PROSPECTUS
                           OMEGA ORTHODONTICS, Inc.
                      1,800,000 Shares of Common Stock and
              1,800,000 Redeemable Common Stock Purchase Warrants

     This Prospectus relates to the offering (the "Offering") of 1,800,000
shares (the "Shares") of common stock, $.01 par value per share (the "Common
Stock"), and 1,800,000 Redeemable Common Stock Purchase Warrants (the
"Warrants") of Omega Orthodontics, Inc., a Delaware corporation (the "Company").
The Shares and Warrants are sometimes hereinafter collectively referred to as
the "Securities." Until the completion of this Offering, the Shares and the
Warrants may only be purchased together on the basis of one Share and one
Warrant, but will be transferable separately immediately following completion of
this Offering. Each Warrant entitles the registered holder thereof to purchase
one share of Common Stock at an initial exercise price of $     per share [110%
of the initial public offering price per share of Common Stock], at any time
during the period commencing       , 1997 [six months after the date of this
Prospectus] and terminating         , 2002 [five (5) years from the date of this
Prospectus.] The Warrant exercise price is subject to adjustment under certain
circumstances. Commencing     , 1998 [eighteen (18) months after the date of
this Prospectus], the Company may redeem the Warrants, in whole but not in part,
at $.10 per Warrant on thirty (30) days' prior written notice to the
warrantholders, provided that the average closing bid price of the Common Stock
as reported on the Nasdaq SmallCap Market ("Nasdaq") equals or exceeds $     per
share [200% of the initial public offering price per share of the Common Stock]
for any twenty (20) trading days within a period of thirty (30) consecutive
trading days ending on the fifth trading day prior to the date of the notice of
redemption. See "Description Securities."

     Prior to this Offering, there has been no public market for the Common
Stock or the Warrants, and there can be no assurance that such a market will
develop after the completion of this Offering or, if developed, that it will be
sustained. It is currently anticipated that the initial public offering prices
of the Common Stock and the Warrants will be $6.00 per share and $.10 per
Warrant, respectively. For information regarding the factors considered in
determining the initial public offering prices of the Securities and the terms
of the Warrants, see "Risk Factors" and "Underwriting." It is anticipated that
upon consummation of the Offering the Shares and the Warrants will be included
for quotation on Nasdaq and listing on the Boston Stock Exchange (the "BSE") and
will trade separately immediately after the Offering under the symbols "OMGA"
and "OMGAW," respectively, with respect to Nasdaq and "OMA" and "OMAW," 
respectively, with respect to the BSE.

                              PROSPECTUS SUMMARY

     The following summary is qualified in its entirety by the more detailed
information and financial statements, including the notes thereto, appearing
elsewhere in this Prospectus. Upon consummation of this Offering, Omega
Orthodontics, Inc. will acquire (the "Acquisitions") the equity interests in the
management services organizations that hold certain assets of and are associated
with seven orthodontic practices (except in the case of one sole proprietorship
where it will acquire certain assets of such proprietorship) (such practices are
referred to collectively as the "Initial Orthodontic Affiliates" and such
management services organizations are referred to collectively as the "Initial
MSOs"). Unless otherwise indicated, all references herein to "Omega" shall mean
Omega Orthodontics, Inc. prior to the consummation of the Acquisitions, and
references herein to the "Company" shall mean Omega after consummation of the
Acquisitions. Except as otherwise indicated, the information in this Prospectus
assumes that (i) the Over-allotment Option is not exercised and (ii) the
Warrants and the warrants to purchase 180,000 shares of Common Stock and/or
180,000 Warrants issued to the Representative in connection with this Offering
(the "Representative's Warrants") are not exercised. See "Underwriting."

     This Prospectus contains forward-looking statements which involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in those forward-looking statements as a result of certain factors,
including those set forth under "Risk Factors" and elsewhere in this Prospectus.
 

                                  The Company

     The Company provides management and marketing services to orthodontic
practices in the United States. Since its inception in August 1996, Omega has
provided these services on a fee for services basis to 10 orthodontic practices,
including four of the Initial Orthodontic Affiliates. Following this Offering,
the Company intends to offer its services primarily under an affiliate
relationship whereby it purchases the equity interests in the management
services organization (individually, an "MSO" and collectively with the Initial
MSOs, the "MSOs") that holds certain assets of and is associated with an
orthodontic practice and enters into a long term management services agreement
(the "Management Services Agreement") with the practice (individually, an
"Orthodontic Affiliate" and collectively with the Initial Orthodontic
Affiliates, the "Orthodontic Affiliates") of the selling orthodontist (the
"Affiliated Orthodontist"). The Company has signed affiliation agreements (the
"Affiliation Agreement") with the seven Initial Orthodontic Affiliates and
letters of intent with four additional practices.

     Upon consummation of the Acquisitions, the Company will enter into
Management Services Agreements with the Initial Orthodontic Affiliates. Pursuant
to these Management Services Agreements, the Company will provide facilities,
support staff and supplies to the Initial Orthodontic Affiliates and will
institute a program of systems, methods and procedures the Company refers to as
the Omega Exceptional Practice Model (the "Model"). The Model is designed to
increase the Orthodontic Affiliate's profitability by focusing on and improving
customer service while simultaneously reducing costs and increasing operating
efficiency.

     Omega seeks to affiliate with established orthodontic practices that Omega
believes have the potential for significant growth utilizing the Model. Omega
considers financial and operational factors that include the practice's gross
income, cost structure, existing treatment contracts, fee schedules, referral
rates and sources, health maintenance organization relationships, case starts,
appointments per day and average treatment times. Omega also evaluates
demographic factors that include the practice's location with respect to the
average income levels and concentrations of families with children in the area.

     The annual market for orthodontic treatment and services is estimated at
$3.6 billion. Based on U.S. census data that indicates that the number of
children between the ages of five and 19 will increase by approximately 10.4
million by the year 2000, the Company expects that the growth in this population
group will result in increased demand for orthodontic services. The orthodontic
marketplace is highly fragmented and consists of approximately 9,000 practicing
orthodontists, a significant majority of whom are sole practitioners. Omega
believes that many orthodontists in practice today have excess patient capacity
and lack the training and resources in management and marketing techniques to
fill that capacity effectively. It is Omega's belief that less than two percent
of the orthodontic practices in the United States are presently managed by
independent, professional management services organizations and that an
opportunity exists for the Company to market and sell its services to the
orthodontic practices that are not currently managed by such organizations.

                                       3

<PAGE>


     The Company's strategy is to (i) enter into Affiliation Agreements and
Management Services Agreements with established orthodontic practices that meet
the Company's criteria and (ii) achieve operating efficiencies and increased
profitability at each such practice through the implementation of the Model. The
Model is designed to permit the practice to meet or exceed patient expectations
by (a) offering flexible payment plans, (b) scheduling convenient appointment
times, (c) ensuring that treatment is delivered on time, (d) updating patients
and their referring dentists regularly on treatment programs and (e) training
staff to anticipate and address patient needs.

     The Company will focus its initial marketing efforts on the practices of
the approximately 4,500 orthodontists over the age of 47 who the Company
believes are planning their transition to retirement. The Company believes it
can generally place a higher value on a mature practice than other potential
buyers, many of whom are recent orthodontic graduates. The Company believes that
this higher valuation, combined with consideration in the form of a combination
of cash, notes and the Company's Common Stock and the opportunity to delegate
managerial and marketing responsibilities to an experienced management team,
generally makes the Company an attractive alternative for orthodontists planning
their transition to retirement. The Company will also target younger
orthodontists who may want to merge their practices with the practice of an
orthodontist in transition or take over such a practice.

                                 The Offering

Securities Offered   ...............  1,800,000 shares of Common Stock and

                                      immediately following completion of this

                                 RISK FACTORS

     An investment in the Securities offered hereby involves a high degree of
risk. In addition to the other information contained in this Prospectus, the
following risk factors should be considered carefully in evaluating the Company
and its business before purchasing the Securities offered hereby. Prospective
investors should be in a position to risk the loss of their entire investment.
This Prospectus contains forward-looking statements which involve risks and
uncertainties. The Company's actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain factors,
including those set forth in the following risk factors and elsewhere in this
Prospectus.

     Limited Operating History; Early Stage Company; History of Losses; No
Assurance of Profitability. Omega was incorporated in August 1996 and has a
limited operating history upon which prospective investors can judge its
performance and prospects. Omega is at an early stage and is subject to all of
the business risks associated with a new enterprise, including constraints on
its financial and personnel resources, lack of established business
relationships and uncertainties regarding affiliations and future revenues.
Omega has generated limited revenues to date, and will not generate any
meaningful revenues until after it consummates a significant number of
affiliations with orthodontic practices. At December 31, 1996, Omega had an
accumulated deficit since inception of $232,112 and a working capital deficiency
of $368,032. The Company anticipates that it will incur operating losses in the
six month period ending June 30, 1997 in connection with a non-recurring charge
for compensation paid to certain consultants and may incur operating losses for
the foreseeable future thereafter. There can be no assurances as to whether the
Company will ever be profitable. See "--Expected Operating Loss in Six Month
Period Ending June 30, 1997" and "Management's Plan of Operation."

     Expected Operating Loss in Six Month Period Ending June 30, 1997. The
Company expects to show a significant loss from operations for the six month
period ending June 30, 1997 due primarily to compensation paid to two
consultants. On April 28, 1997, each of Dr. Glovsky, the Chairman of the Board
of the Company, and The Mayflower Group, Ltd., a private banking firm
("Mayflower," and together with Dr. Glovsky, the "Consultants"), received
225,000 shares of Common Stock for consulting services to Omega and will receive
approximately $421,000 of cash payments over three years beginning in January
1998. See "Certain Transactions." The Company will recognize a non-recurring
compensation expense reflecting delivery of such shares and these payment
obligations in April 1997 of approximately $2.2 million. This expense is
comprised of approximately $1.4 million attributable to the Common Stock and an
aggregate of approximately $842,000 attributable to the payment obligation. See
"Management's Plan of Operation--Plan of Operation."

     Going Concern Report. Omega's independent auditors have stated in their
report on Omega's financial statements as of December 31, 1996 that Omega's
accumulated deficit and working capital deficiency raise substantial doubt,
absent successful completion of this Offering, about Omega's ability to continue
as a going concern. See "Management's Plan of Operation" and "Financial
Statements."

     Risks Associated with Expansion. Omega has signed Affiliation Agreements
with the seven Initial Orthodontic Affiliates and expects to consummate the
Acquisitions concurrently with the closing of this Offering. Omega has also
executed non-binding letters of intent to affiliate with four additional
orthodontic practices. At the end of the 12 months following this Offering, the
Company intends to manage approximately 31 Orthodontic Affiliates. The success
of the Company's expansion strategy will depend on a number of factors,
including (i) the Company's ability to attract orthodontists to affiliate with
the Company, the availability of suitable markets and the Company's ability to
obtain good locations within those markets; (ii) the Company's ability to locate
existing practices for affiliation, affiliate with such practices on favorable
terms and successfully integrate the affiliated operations into the Company's
existing operations; (iii) the availability of adequate financing to affiliate
with orthodontic practices; and (iv) regulatory constraints. A shortage of
available orthodontists with the skills and experience required by the Company
would have a material adverse effect on the Company's expansion plans. There can
be no assurance that the Company's expansion strategy will be successful, that
modifications to the Company's strategy will not be required or that the Company
will be able to manage effectively and enhance the profitability of its
Orthodontic Affiliates. See "Business--Business Strategy."

     Possible Need for Additional Financing. The Company's expansion strategy
will require substantial capital resources. Although the Company believes that
the net proceeds of this Offering, together with cash from operations, will be
sufficient to satisfy its cash requirements for at least 12 months following the
date of this Prospectus, there can be no assurance that additional funds will
not be needed. The Company expects that its capital needs over the

                                       6

<PAGE>

next several years will substantially exceed capital generated from operations
and the net proceeds of this Offering. To finance its future capital needs, the
Company plans to issue, from time to time, additional debt or equity securities,
including notes and Common Stock in connection with its planned affiliations.
There can be no assurance that the Company will be able to raise additional
funds when needed on satisfactory terms to the Company or at all. If additional
funds are raised through the issuance of equity securities, dilution to the
Company's stockholders may result, and if additional funds are raised through
the incurrence of debt, the Company likely would become subject to financial
covenants and restrictions on its operations and finances. If adequate financing
is not available when needed or on terms acceptable to the Company, the
Company's expansion strategy may be materially adversely affected. See
"Management's Plan of Operation."

     Additional Debt to Finance Affiliations. In connection with the
Acquisitions, the Company expects to issue five year, 8.5% notes aggregating
approximately $794,000 to five Affiliated Orthodontists. During the 12 months
following the consummation of the Acquisitions, the Company intends to affiliate
with and manage an additional 24 Orthodontic Affiliates. In connection with such
additional affiliations, the Company expects that it may issue notes aggregating
approximately $4.8 million to new Affiliated Orthodontists. The Company believes
that it will be able to issue these notes on substantially similar terms to the
terms of the notes to be issued in connection with the Acquisitions. There can
be no assurance, however, that the Company will be able to issue notes in
connection with future affiliations in amounts and on terms acceptable to the
Company. If the Company is unable to issue notes in connection with future
affiliations in amounts and on terms acceptable to the Company, the Company's
expansion strategy may be materially adversely affected. See "Management's Plan
of Operation."

     Dependence on Orthodontic Affiliates. The Company will receive fees for
management services provided to Orthodontic Affiliates under Management Services
Agreements, but will not employ orthodontists or control the practices of its
Orthodontic Affiliates. The Company's revenue is dependent on revenue generated
by the Company's Orthodontic Affiliates and, therefore, the performance and
professional reputation of Affiliated Orthodontists and Orthodontic Affiliates
are essential to the Company's success. The Management Services Agreements with
the Orthodontic Affiliates are for terms of 20 years and are renewable at the
election of the Company for two additional 10 year periods. The Management
Services Agreements may only be terminated by either party for "cause," which
includes a material default by or bankruptcy of the other party. Any material
loss of revenue by the Orthodontic Affiliates would have a material adverse
effect on the Company. See "Business--Agreements with Affiliated Orthodontists."
 

     Professional Liability. The Orthodontic Affiliates provide orthodontic
services to the public and are exposed to the risk of professional liability and
other claims. The Company does not control the practice of orthodontics by its
Orthodontic Affiliates or the compliance with regulatory and other requirements
directly applicable to the orthodontists and their practices. The Company might
nevertheless be held liable for negligence on their part.

     The Management Services Agreements will require the Orthodontic Affiliates
to maintain, at their expense, professional liability insurance for themselves
and each orthodontist employed by or otherwise providing orthodontic services
for the Orthodontic Affiliate in the minimum amount of $500,000 per occurrence
and $1,000,000 in the aggregate. In addition, each Orthodontic Affiliate will
undertake to comply with all applicable regulations and requirements, and the
Company will be indemnified under the Management Services Agreements for claims
against the Company arising in connection with actions by the Orthodontic
Affiliates. The Company has applied for general liability insurance for itself
and will require that it be named as an additional insured party on the
professional liability insurance policies of the Orthodontic Affiliates pursuant
to the Management Services Agreement. The Company does not maintain professional
liability insurance for itself.

     There can be no assurance that the Company, its employees, the Orthodontic
Affiliates or the licensed orthodontists employed by or associated with the
Orthodontic Affiliate will not be subject to claims in amounts that exceed the
coverage limits or that such coverage will be available when needed. Further,
there can be no assurance that professional liability or other insurance will
continue to be available to the Orthodontic Affiliates in the future at adequate
levels or at an acceptable cost. A successful claim against the Company or an
Orthodontic Affiliate in excess of the relevant insurance coverage could have a
material adverse effect upon the Company. Claims against the Company, regardless
of the merits or eventual outcomes, may also have a material adverse effect on
the Company.

     Government Regulation. Federal and state laws extensively regulate the
relationships among providers of health care services, physicians and other
clinicians. These laws include federal fraud and abuse provisions that

                                       7

<PAGE>

prohibit the solicitation, receipt, payment, or offering of any direct or
indirect remuneration for the referral of patients for which reimbursement is
made under any federal or state funded health care program or for the
recommending, leasing, arranging, ordering or providing of services covered by
such programs. States have similar laws that apply to patients covered by
private and government programs. Federal fraud and abuse laws also impose
restrictions on physicians' referrals for designated health services covered
under a federal or state funded health care program to entities with which they
have financial relationships. Various states have adopted similar laws that
cover patients in private programs as well as government programs. There can be
no assurance that the federal and state governments will not consider additional
prohibitions on physician ownership, directly or indirectly, of facilities to
which they refer patients, which could adversely affect the Company. Violations
of these laws may result in substantial civil or criminal penalties for
individuals or entities, including large civil money penalties and exclusion
from participation in federal or state health care programs. See
"Business--Government Regulation."

     Moreover, the laws of many states prohibit physicians from sharing
professional fees, or "splitting fees," with anyone other than a member of the
same profession. These laws and their interpretations vary from state to state
and are enforced by the courts and by regulatory authorities with broad
discretion. Expansion of the operations of the Company to certain jurisdictions
may require structural and organizational modifications of the Company's form of
relationship with Orthodontic Affiliates, which could have an adverse effect on
the Company. Although the Company believes its operations as currently expected
to be conducted are in material compliance with existing applicable laws, there
can be no assurance that review of the Company's business by courts or
regulatory authorities will not result in a determination that could adversely
affect the operations of the Company or that the health care regulatory
environment will not change so as to restrict the Company's existing operations
or its expansion.

     State Laws Regarding Prohibition of Corporate Practice of Orthodontics. The
Orthodontic Affiliates are expected to be formed as professional corporations
owned by one or more orthodontists licensed to practice dentistry under
applicable state law in states that prohibit the corporate practice of
dentistry. Corporations such as the Company are not permitted under certain
state laws to practice dentistry or exercise control over the dental judgments
or decisions of practitioners. Corporate practice of dentistry laws and their
interpretations vary from state to state and are enforced by the courts and by
regulatory authorities with broad discretion. The Company anticipates that it
will perform only non-orthodontic administrative services, will not represent to
the public that it offers orthodontic services and will not exercise influence
or control over the practice of orthodontics by the practitioners with whom it
contracts. Expansion of the operations of the Company to certain jurisdictions
may require structural and organizational modifications of the Company's form of
relationship with Orthodontic Affiliates in order to comply with the dental
practice laws, which could have an adverse effect on the Company. Although the
Company believes its operations as currently expected to be conducted will be in
material compliance with existing applicable laws, there can be no assurance
that the Company's structure will not be challenged as constituting the
unlicensed practice of dentistry or that the enforceability of the agreements
underlying this structure will not be limited. If such a challenge were made
successfully in any state, the Company could be subject to civil and criminal
penalties under such state's laws and could be required to restructure its
contractual arrangements in that state. Such results or the inability to
restructure its contractual arrangements could have a material adverse effect
upon the Company.

     Dependence on Key Personnel. The success of the Company is dependent upon
the continued services of the Company's senior management, particularly upon its
Chief Executive Officer and President, Mr. Robert J. Schulhof, and its Director
of Affiliate Programs, Dr. Dean C. Bellavia. Both Mr. Schulhof and Dr. Bellavia
have entered into three year employment agreements with the Company, but there
can be no assurance that either of them will continue in the employ of the
Company for the full term of his employment agreement. The Company has a
"key-man" life insurance policy on the life of Mr. Schulhof providing benefits
to the Company of $1 million upon the death of Mr. Schulhof. The loss of the
services of Mr. Schulhof or Dr. Bellavia, or the inability to attract other
qualified employees, could have a material adverse effect on the Company. See
"Management--Employment Agreements."

     Competition. The business of providing orthodontic services is highly
competitive in each market in which the Company intends to operate. Each of the
Orthodontic Affiliates faces competition from other orthodontists or general
dentists in the communities served, many of whom may have more established
practices in the market or greater financial and other resources than the
Orthodontic Affiliate. At this time, the Company believes there are several
other companies actively involved in consolidating and managing orthodontic
practices throughout the United States. These companies have greater financial,
marketing and other resources than the Company. In addition, there are companies
pursuing similar strategies with respect to dental specialties, including
orthodontics, and

                                       8

<PAGE>

additional companies with similar objectives may enter the Company's markets and
compete with the Company. Many of the Company's competitors may have
substantially greater financial and other resources than the Company. There can
no be assurance that the Company will be able to compete effectively. See
"Business--Competition."

     Health Care Reform. Although Congress failed to pass comprehensive health
care reform legislation in 1996, the Company anticipates that Congress and state
legislatures will continue to review and assess alternative health care delivery
and payment systems and may in the future propose and adopt legislation
effecting fundamental changes in the health care delivery system. The Company
cannot predict the ultimate timing, scope or effect of any legislation
concerning health care reform. Any proposed federal legislation, if adopted,
could result in significant changes in the availability, delivery, pricing and
payment for health care services and products. Various states agencies also have
undertaken or are considering significant health care reform initiatives.
Although it is not possible to predict whether any health care reform
legislation will be adopted or, if adopted, the exact manner and the extent to
which the Company will be affected, it is likely that the Company will be
affected in some fashion, and there can be no assurance that any health care
reform legislature, if and when adopted, will not have a material adverse effect
on the Company.

     Dependence on Third Party Reimbursement. A significant portion of the
revenue of the Orthodontic Affiliates on which the Company's revenue will depend
comes from commercial dental insurance and preferred provider plans. These
providers and programs are regulated at the state or federal level. There are
increasing and significant public sector pressures to contain health care costs
and to restrict reimbursement rates for dental services. Changes in the level of
support by federal and state governments of health care services, the methods by
which such services may be delivered, and the prices of such services may all
have a material impact on revenue of the Orthodontic Affiliates, which in turn
could have a material adverse effect on the Company.

     Certain Anti-takeover Provisions; Preferred Stock. Certain provisions of
the Company's Certificate of Incorporation, as amended (the "Certificate of
Incorporation"), and By-Laws and Delaware law could have the effect of delaying
or preventing a change in the control of the Company, even if a change in
control were in the stockholders' interest. The Company's Certificate of
Incorporation allows the Board to determine the terms of the preferred stock
which may be issued by the Company without approval of the holders of the Common
Stock. Such preferred stock could have voting and conversion rights that
adversely affect the voting power of the holders of Common Stock, or could
result in one or more classes of outstanding securities that would have
dividend, liquidation or other rights superior to those of the Common Stock.
Issuance of such preferred stock may have an adverse effect on the then
prevailing market price of the Common Stock and Warrants and could enable the
Board to prevent changes in the management and control of the Company.
Additionally, the Company is subject to the anti-takeover provisions of Section
203 of the Delaware General Corporation Law which prohibits the Company from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved in
a prescribed manner. Section 203 could have the effect of delaying or preventing
a change of control of the Company. See "Description of
Securities--Anti-takeover Provisions."

     Shares Eligible for Future Sale. Of the 3,800,655 shares of Common Stock
and 1,800,000 Warrants to be outstanding upon completion of this Offering, the
1,800,000 shares of Common Stock and the 1,800,000 Warrants (2,070,000 shares of
Common Stock and 2,070,000 Warrants if the Over-allotment Option is exercised in
full) will be immediately freely tradeable without restriction under the
Securities Act of 1933, as amended (the "Securities Act"), except for any
securities purchased by an "affiliate" of the Company (as that term is defined
in the Securities Act), which securities will be subject to the resale
limitations of Rule 144 under the Securities Act. All of the remaining 2,000,655
shares of Common Stock outstanding are "restricted securities," as that term is
defined in Rule 144 under the Securities Act and may, under certain
circumstances, be sold without registration under the Securities Act. The sale,
or availability for sale, of substantial amounts of Common Stock in the public
market subsequent to this Offering pursuant to Rule 144 or otherwise could
materially adversely affect the market price of the Common Stock and could
impair the Company's ability to raise additional capital through the sale of its
equity securities or debt financing.

     Notwithstanding the foregoing, each officer and director of Omega and all
holders of the shares of Common Stock and options to acquire shares of Common
Stock have agreed not to, directly or indirectly, offer, sell, transfer, pledge,
assign, hypothecate or otherwise encumber or dispose of any of the Company's
securities, whether or not presently owned, for a period of 24 months after the
date of this Prospectus without the prior written consent of

                                       9

<PAGE>

the Company and the Representative. After such 24 month period, all 2,000,655 of
such shares of Common Stock may be sold in accordance with Rule 144.

     Concentration of Ownership. Upon consummation of this Offering, directors
and executive officers of the Company will own beneficially in the aggregate
approximately 35.8% of the outstanding shares of Common Stock. Accordingly, the
Company's executive officers and directors will have the ability to elect a
majority of the Company's directors and otherwise control the Company. See
"Principal Stockholders."

     Immediate Substantial Dilution; Disparity of Consideration. The purchasers
of the shares of Common Stock in this Offering will experience immediate and
substantial dilution in the net tangible book value of the shares of Common
Stock from the initial public offering price in the amount of $4.83 per share,
or approximately 81% per share. Additional dilution to future net tangible book
value per share may occur upon the exercise of the Warrants, the
Representative's Warrants and options that are outstanding or to be issued under
the Company's Incentive Stock Plan. The current stockholders of Omega, including
the directors and persons or entities affiliated with them, acquired their
shares of Common Stock for nominal consideration. As a result, new investors
will bear substantially all of the risks inherent in an investment in the
Company. See "Capitalization," "Dilution" and "Certain Transactions."

     Absence of Dividends. Omega has never declared or paid dividends on its
Common Stock and does not anticipate paying any dividends in the foreseeable
future. The Company expects that future earnings, if any, will be retained for
the growth and development of the Company's business and, accordingly, the
Company does not anticipate that any dividends will be declared or paid on the
Common Stock for the foreseeable future. See "Dividend Policy."

     No Prior Public Market for the Securities; Arbitrary Determination of
Offering Price; Price Volatility. Prior to this Offering, there has been no
public market for the Securities, and there can be no assurance that an active
trading market for any of the Securities will develop or, if developed, be
sustained after the Offering. See "Underwriting." The initial public offering
prices of the Securities and the exercise price and terms of the Warrants have
been determined arbitrarily by negotiations between Omega and the
Representative. Factors considered in such negotiations, in addition to
prevailing market conditions, included the history of and prospects for the
industry in which Omega competes, an assessment of Omega's management, the
prospects of the Company, its capital structure and certain other factors as
were deemed relevant. Therefore, the public offering prices of the Securities
and the exercise prices and terms of the Warrants do not necessarily bear any
relationship to Omega's assets, book value, results of operations or any other
established valuation criteria and may not be indicative of prices that may
prevail at any time or from time to time in the public market for the
Securities. See "Underwriting." The securities markets have from time to time
experienced significant price and volume fluctuations that may be unrelated to
the operating performance of particular companies. In addition, the market
prices of the common stock of many publicly traded health care companies have in
the past been, and can in the future be expected to be, especially volatile.
Announcements of regulatory developments on both the federal and state level and
economic and other external factors, as well as period-to-period fluctuations in
the Company's financial results, may have a significant impact on the market
prices of the Securities.

     Portion of Offering Proceeds Benefiting Management. Net proceeds to the
Company from the sale of the Securities offered hereby will be used to repay
$30,000, $50,000 and $25,000 of the Company's Bridge Notes held by Dr. Glovsky,
the Chairman of the Board of the Company, Dr. Bellavia, a director of the
Company, and Dr. Grove, a director of the Company, respectively, and to pay
approximately $333,600 to Dr. Grove, as partial consideration for acquiring
certain assets of his practice in connection with the Acquisitions. In addition,
a portion of the net proceeds from the sale of Securities may be used to make 
certain cash payments to Dr. Glovsky and Mayflower, a principal stockholder of
the Company, in connection with consulting services rendered by them to Omega.
See "Use of Proceeds" and "Certain Transactions."

     Potential Adverse Effect of Representative's Warrants. At the consummation
of the Offering, the Company will sell to the Representative and/or its
designees, for nominal consideration, warrants to purchase up to 180,000 shares
of Common Stock and/or 180,000 Warrants (the "Representative's Warrants"). The
Representative's Warrants will be exercisable for a period of four years
commencing one year after the effective date of this Offering, at an exercise
price of $         per share [120% of the public offering price of the Common
Stock] and $       per Warrant [120% of the public offering price of the
Warrants]. The Warrants obtained upon exercise of the Representative's Warrants
will be exercisable for a period of four years commencing one year after the
effective date of this Offering, at an exercise price of $     per share [110%
of the initial public offering price of the Common Stock]. For the term of the
Representative's Warrants, the holders thereof will have, at nominal cost, the
opportunity to profit from a rise in the market price of the Securities without
assuming the risk of ownership, with a resulting

                                       10

<PAGE>

dilution in the interest of other security holders. As long as the
Representative's Warrants remain unexercised, the Company's ability to obtain
additional capital might be adversely affected. Moreover, the Representative may
be expected to exercise the Representative's Warrants at a time when the Company
would, in all likelihood, be able to obtain any needed capital through a new
offering of its securities on terms more favorable than those provided by the
Representative's Warrants. See "Underwriting."

     Speculative Nature of the Warrants. The Warrants do not confer any rights
of Common Stock ownership on their holders, such as voting rights or the right
to receive dividends, but rather merely represent the right to acquire shares of
Common Stock at a fixed price for a limited period of time. Specifically,
commencing           , 1997 [six months after the date of this Prospectus],
holders of the Warrants may exercise their right to acquire Common Stock and pay
an exercise price of $      per share [110% of the initial public offering price
per share of Common Stock], subject to adjustment upon the occurrence of certain
dilutive events, until        , 2002 [five years after the date of this
Prospectus], after which date any unexercised Warrants will expire and have no
further value. Moreover, following the completion of this Offering, the market
value of the Warrants will be uncertain and there can be no assurance that the
market value of the Warrants will equal or exceed their initial public offering
price. There can be no assurance that the market price of the Common Stock will
ever equal or exceed the exercise price of the Warrants and, consequently,
whether it will ever be profitable for holders of the Warrants to exercise the
Warrants.

     Potential Adverse Effect of Redemption of Warrants. Commencing          ,
1998 [18 months after the date of this Prospectus], the Warrants are subject to
redemption by the Company at $0.10 per Warrant on thirty days' prior written
notice to the warrantholders if the average closing bid price of the Common
Stock as reported on Nasdaq equals or exceeds $      per share [200% of the
initial public offering price of the Common Stock] of Common Stock for any 20
trading days within a period of thirty (30) consecutive trading days ending on
the fifth trading day prior to the date of the notice of redemption. If the
Warrants are redeemed, holders of the Warrants will lose their rights to
exercise the Warrants after the expiration of the 30-day notice of redemption
period. Upon receipt of a notice of redemption, holders would be required to:
(i) exercise the Warrants and pay the exercise price at a time when it may be
disadvantageous for them to do so, (ii) sell the Warrants at the current market
price, if any, when they might otherwise wish to hold the Warrants or (iii)
accept the redemption price which is likely to be substantially less than the
market value of the Warrants at the time of redemption. See "Description of
Securities--Warrants."

     Potential Adverse Effect of Substantial Shares of Common Stock Reserved.
The Company has reserved a total of 2,693,333 shares of Common Stock for
issuance as follows: (i) 1,800,000 shares for issuance upon exercise of the
1,800,000 Warrants; (ii) 180,000 shares for issuance upon exercise of the
Representative's Warrants; (iii) 180,000 shares for issuance upon exercise of
the Warrants issuable upon exercise of the Representative's Warrants; (iv)
83,333 shares (assuming an initial public offering price per share of $6.00) for
issuance upon exercise of options to be granted upon consummation of the
Acquisitions to an Affiliated Orthodontist; (v) 350,000 shares for issuance upon
exercise of options granted to three officers of the Company pursuant to the
Stock Option Plan; and (vi) 100,000 shares for issuance pursuant to grants that
may be made under the Stock Option Plan. The existence of the Warrants, the
Representative's Warrants and any other options or warrants may adversely affect
the Company's ability to consummate future equity financings. Further, the
holders of such warrants and options may exercise them at a time when the
Company would otherwise be able to obtain additional equity capital on terms
more favorable to the Company. See "Shares Eligible for Future Sale."

     Legal Restrictions on Sales of Shares Underlying the Warrants. The Warrants
are not exercisable unless, at the time of the exercise, the Company has a
current prospectus covering the shares of Common Stock issuable upon exercise of
the Warrants, and such shares have been registered, qualified or deemed to be
exempt under the securities laws of the state of residence of the exercising
holder of the Warrants. Although the Company has agreed to use its best efforts
to keep a registration statement covering the shares of Common Stock issuable
upon the exercise of the Warrants effective for the term of the Warrants, if it
fails to do so for any reason, the Warrants may be deprived of value.

     The Shares and Warrants are separately transferable immediately upon
issuance. Purchasers may buy Warrants in the aftermarket in, or may move to,
jurisdictions in which the shares underlying the Warrants are not so registered
or qualified during the period that the Warrants are exercisable. In this event,
the Company would be unable to issue shares to those persons desiring to
exercise their Warrants, and holders of Warrants would have no choice but to
attempt to sell the Warrants in a jurisdiction where such sale is permissible or
allow them to expire unexercised. See "Description of Securities."

     Limitations on Liability and Indemnification Matters. As permitted by the
Delaware General Corporation Law, the Company has included in its Certificate of
Incorporation a provision to eliminate the personal liability

                                       11

<PAGE>

of its directors for monetary damages for breach or alleged breach of their
fiduciary duties as directors, subject to certain exceptions. In addition, the
By-Laws of the Company provide that the Company is required to indemnify its
officers and directors under certain circumstances, including those
circumstances in which indemnification would otherwise be discretionary and the
Company is required to advance expenses to its officers and directors as
incurred in connection with proceedings against them for which they may be
indemnified. See "Description of Securities--Limitations on Liability of
Officers and Directors."

     Representative's Potential Influence on the Market. A significant amount of
the Securities offered hereby may be sold to customers of the Representative.
Such customers subsequently may engage in transactions for the sale or purchase
of such Securities through or with the Representative. If it participates in the
market, as a market maker or otherwise, the Representative may exert a
dominating influence on the market, if one develops, for the Securities
described in this Prospectus. Such market making activity may be discontinued at
any time. The price and liquidity of the Common Stock and the Warrants may be
significantly affected by the degree, if any, of the Representative's
participation in such market. See "Underwriting."

     No Assurance of Nasdaq Listing; Risk of Low-Priced Securities; Risk of
Application of Penny Stock Rules. The Board of Governors of the National
Association of Securities Dealers, Inc. has established certain standards for
the initial listing and continued listing of a security on Nasdaq. The standards
for initial listing require, among other things, than an issuer have total
assets of $4,000,000 and capital and surplus of at least $2,000,000; that the
minimum bid price for the listed securities be $3.00 per share; that the minimum
market value of the public float (the shares held by non-insiders) be at least
$2,000,000; and that there be at least two market makers for the issuer's
securities. The maintenance standards require, among other things, that an
issuer have total assets of at least $2,000,000 and capital and surplus of at
least $1,000,000; that the minimum bid price for the listed securities be $1.00
per share; that the minimum market value of the "public float" be at least
$1,000,000; and that there be at least two market makers for the issuer's
securities. A deficiency in either the market value of the public float or the
bid price maintenance standard will be deemed to exist if the issuer fails the
individual stated requirement for ten consecutive trading days. If an issuer
falls below the bid price maintenance standard, it may remain on Nasdaq if the
market value of the public float is at least $1,000,000 and the issuer has
$2,000,000 in equity. Nasdaq has recently proposed new maintenance criteria
which, if implemented, would eliminate the exception to the $1.00 per share
minimum bid price and require, among other things, $2,000,000 net tangible
assets, $1,000,000 market value of the public float and adherence to certain
corporate governance provisions There can be no assurance that the Company will
continue to satisfy the requirements for maintaining a Nasdaq listing. If the
Company's securities were to be excluded from Nasdaq, it would adversely affect
the prices of such securities and the ability of holders to sell them, and the
Company would be required to comply with the initial listing requirements to be
relisted on Nasdaq.

     If the Company is unable to satisfy maintenance requirements and the price
per share were to drop below $5.00, then unless the Company satisfied certain
net asset tests, the Company's securities would become subject to certain penny
stock rules promulgated by the Securities and Exchange Commission (the
"Commission"). The penny stock rules require a broker-dealer, prior to a
transaction in a penny stock not otherwise exempt from the rules, to deliver a
standardized risk disclosure document prepared by the Commission that provides
information about penny stocks and the nature and level of risks in the penny
stock market. The broker-dealer also must provide the customer with current bid
and offer quotations for the penny stock, the compensation of the broker-dealer
and its salesperson in the transaction and monthly account statements showing
the market value of each penny stock held in the customer's account. In
addition, the penny stock rules require that prior to a transaction in a penny
stock not otherwise exempt from such rules, the broker-dealer must make a
special written determination that the penny stock is a suitable investment for
the purchaser and receive the purchaser's written agreement to the transaction.
These disclosure requirements may have the effect of reducing the level of
trading activity in the secondary market for a stock that becomes subject to the
penny stock. If the Common Stock becomes subject to the penny stock rules,
investors in the Offering may find it more difficult to sell their shares.

     Risks Associated with Forward-Looking Statements Included in this
Prospectus. This Prospectus contains certain forward-looking statements,
including, without limitation, the unaudited pro forma financial statements of
Omega, regarding the plans and objectives of management for future operations
including plans and objectives relating to the development of the Orthodontic
Affiliates. The forward-looking statements included herein are based on current
expectations that involve numerous risks and uncertainties. The Company's plans
and objectives are based on a successful execution of the Company's expansion
strategy and assumptions that the Orthodontic Affiliates will be profitable,
that the orthodontic industry will not change materially or adversely, and that
there

                                       12

<PAGE>

will be no unanticipated material adverse change in the Company's operations or
business. Assumptions relating to the foregoing involve judgments with respect
to, among other things, future economic, competitive and market conditions and
future business decisions, all of which are difficult or impossible to predict
accurately and many of which are beyond the control of the Company. Although the
Company believes that its assumptions underlying the forward-looking statements
are reasonable, any of the assumptions could prove inaccurate and, therefore,
there can be no assurance that the forward-looking statements included in this
Prospectus will prove to be accurate. In light of the significant uncertainties
inherent in the forward-looking statements included herein, particularly in view
of the Company's early stage of operations, the inclusion of such information
should not be regarded as a representation by the Company or any other person
that the objectives and plans of the Company will be achieved.

(1) The amount set forth with respect to each purpose represents the Company's
    current estimate of the approximate amount of the net proceeds that will be
    used for such purpose. The Company reserves the right, however, to change
    the amount of such net proceeds that will be used for any purpose to the
    extent that management determines that such change is advisable.
    Consequently, management of the Company will have broad discretion in
    determining the manner in which the net proceeds of this Offering are
    applied.

(2) The Bridge Notes are in the aggregate principal amount of $875,000 as of
    April 30, 1997, bear interest at the rate of 15% per annum and are payable
    upon the earlier of the closing of this Offering or September 30, 1997. The
    net proceeds from the sale of the Bridge Notes were used for certain
    expenses of this Offering and for working capital and general corporate
    purposes. See "Management's Plan of Operation--Liquidity and Capital
    Resources." Dr. Glovsky, Dr. Bellavia and Dr. Grove, each a director of the
    Company, will receive an aggregate of $105,000 in payment of the Bridge
    Notes that they purchased from the Company. See "Certain Transactions."

(3) The Company plans to consummate the Acquisitions concurrently with the
    closing of this Offering. In connection with the Acquisitions, the Company
    will acquire the equity interests in the Initial MSOs associated with the
    seven Initial Orthodontic Affiliates (except in the case of one sole
    proprietorship where it will acquire certain assets of such proprietorship).
    The costs of the Acquisitions will be paid through a combination of (i) cash
    aggregating approximately $2,098,000, (ii) five year 8.5% notes aggregating
    approximately $794,000, (iii) 315,655 shares of Common Stock of the Company
    (assuming an initial public offering price per share of $6.00) and (iv) an
    option to acquire 83,333 shares of Common Stock (assuming an initial public
    offering price per share of $6.00) at an exercise price equal to the initial
    public offering price per share. See "Management's Plan of Operation." Dr.
    Grove, one of the Company's directors, has agreed to sell certain assets of
    his practice to the Company concurrently with the closing of this Offering
    and, in partial consideration therefor, will receive approximately $333,600
    of the net proceeds of this Offering, a five year 8.5% note in the amount of
    approximately $333,600 and 55,595 shares of Common Stock of the Company
    (assuming an initial public offering price per share of $6.00). See "Certain
    Transactions."

(4) The Company plans to enter into Affiliation Agreements and Management
    Service Agreements with up to an additional 24 Orthodontic Affiliates during
    the 12 months following the closing of this Offering. The Company intends to
    finance these transactions through a combination of cash payments and
    issuances of notes and shares of Common Stock of the Company. The Company
    estimates that on average it will need approximately $200,000 of cash to
    complete each such transaction. See "Management's Plan of Operation."


                                       15

(5)  The Company plans to develop or acquire certain software for use by
     Orthodontic Affiliates in implementing the Model and estimates that
     development or acquisition costs will be approximately $200,000.

(6)  The remaining portion of the net proceeds will be allocated to working
     capital and will be used by the Company to fund operations as required,
     including amounts required to pay officers' salaries, consultant and
     professional fees (including approximately $270,000 which reflects the
     first two cash payments to be made to Dr. Glovsky and Mayflower over three
     years beginning in January 1998), office-related expenses and other
     corporate expenses, including the leasing of office space in Massachusetts
     where the Company intends to locate its financial operations and staff. See
     "Management's Plan of Operation--Plan of Operation" and
     "Business--Facilities." The additional net proceeds received from the
     exercise of the Over-allotment Option, if any, will be used for working
     capital and general corporate purposes.

     The Company anticipates, based on current plans and assumptions relating to
its operations, that the net proceeds of this Offering, together with net cash
from operations, should be sufficient to satisfy the Company's cash requirements
for at least the 12 months after the date of this Prospectus. The Company's
future liquidity and capital funding requirements will depend on numerous
factors, including the availability of orthodontic practices meeting the
Company's affiliation criteria, the extent to which the Orthodontic Affiliates
gain market acceptance, marketing activities and competition. There can be no
assurance that additional capital, if needed, will be available on terms
acceptable to the Company, or at all. Furthermore, any additional equity
financing may be dilutive to stockholders, and debt financing, if available,
will likely include restrictive covenants and provide for security interests in
the Company's assets. The failure of the Company to raise capital on acceptable
terms when needed could have a material adverse effect on the Company. See "Risk
Factors--Possible Need for Additional Financing" and "Risk Factors--Risks
Associated with Expansion." Pending the aforementioned uses, the net proceeds of
this Offering will be invested in interest-bearing government securities or
short-term, investment grade securities.

                                DIVIDEND POLICY

     The Company has never declared or paid dividends on its Common Stock. The
Company expects that future earnings, if any, will be retained for the growth
and development of the Company's business and, accordingly, the Company does not
anticipate that any dividends will be declared or paid on the Common Stock for
the foreseeable future. The declaration, payment and amount of future dividends,
if any, will depend upon the future earnings, results of operations, financial
position and capital requirements of the Company, among other factors.

                                   DILUTION

     At December 31, 1996, after giving effect to (a) the issuance of 10,000
shares of Common Stock as compensation for past services to LMG, (b) the
issuance of Bridge Notes in the aggregate principal amount of $300,000, and
60,000 shares of Common Stock issued in connection therewith, since December 31,
1996, (c) a non-recurring compensation expense of approximately $2.2 million
paid to two consultants, which expense is comprised of approximately $1.4
million attributable to the release of 450,000 shares of Common Stock and an
aggregate of approximately $842,000 in cash payments to be paid over three years
beginning in January 1998 and (d) the assumed consummation of the Acquisitions,
the pro forma negative net tangible book value of the Company was ($4,110,205),
or $(2.05) per share. "Pro forma net tangible book value per share" is
determined by dividing the Company's pro forma net tangible book value (total
pro forma tangible assets less total pro forma liabilities) by the pro forma
number of shares of Common Stock outstanding. After giving effect to the sale by
the Company of the Securities offered hereby and the initial application of the
net proceeds therefrom, the adjusted pro forma net tangible book value of the
Company at December 31, 1996 would have been $4,442,395, or $1.17 per share.
This represents an immediate increase in pro forma net tangible book value of
$3.22 per share to existing stockholders and an immediate dilution in pro forma
net tangible book value of $4.83 per share (or approximately 81%) to new
investors purchasing the shares of Common Stock in this Offering. The following
table illustrates this per share dilution:

Assumed initial public offering price..................................  $6.00
Pro forma negative net tangible book value prior to this
 Offering ................................................  $(2.05)
Increase attributable to new investors   .................    3.22
                                                            ------
Pro forma net tangible book value after this Offering   ...............   1.17
                                                                         ------
Dilution in pro forma net tangible book value to new investors   ......  $4.83
                                                                         ======


     In the event the Over-allotment Option is exercised in full, the pro forma
net tangible book value as of December 31, 1996 would be $5,875,285, or $1.44
per share of Common stock, which would result in immediate dilution in net
tangible book value to new investors of approximately $4.56 per share.

     The following table sets forth, at December 31, 1996, after giving pro
forma effect to the issuance of shares to the Affiliated Orthodontists as
partial consideration for the consummation of the Acquisitions at the assumed
initial public offering price of the Common Stock, the total consideration paid
and the average price paid per share of Common Stock by existing stockholders,
new investors in this Offering and the Affiliated Orthodontists:

     This Prospectus contains forward-looking statements which involve risks and
uncertainties. See "Risk Factors--Risks Associated with Forward-Looking
Statements Included in this Prospectus." Actual events or results may differ
materially from those discussed in forward-looking statements as a result of
various factors, including, but not limited to, those discussed in "Risk
Factors."

General

     Omega was incorporated in Delaware in August 1996. It was founded by the
principals of OMEGA, LLC, a California-based orthodontic practice management and
consulting firm. Following this Offering, the Company intends to offer its
services primarily under an affiliate relationship whereby it will purchase the
equity interests in the orthodontic practice's MSO pursuant to an Affiliation
Agreement and enter into a long term Management Services Agreement with the
Affiliated Orthodontist's Orthodontic Affiliate. Pursuant to the Management
Services Agreement, the Company will receive a monthly management fee for
providing all of the Orthodontic Affiliate's practice needs, including
facilities, support staff and supplies, as well as a program of systems, methods
and procedures designed to enhance the growth, efficiency and profitability of
the Orthodontic Affiliate.

     Pursuant to the Affiliation Agreement, the Affiliated Orthodontist will
typically convert his existing professional corporation into a general
corporation that will function as the MSO and create a new professional
corporation (the Orthodontic Affiliate) through which the Affiliated
Orthodontist will continue to provide orthodontic care. The MSO will retain
certain assets and liabilities which will typically include the lease for the
Orthodontic Affiliate's office space, clinical supplies and equipment and office
furniture, supplies and equipment. The Company will generally acquire all of the
equity interests of the MSO from the Affiliated Orthodontist, the purchase price
for which is determined through an assessment of immediate and future return on
investment. The MSO typically is acquired for a combination of cash, five year
notes and unregistered Common Stock or stock options. The average MSO purchase
price is expected to be approximately $600,000, of which the cash portion is
expected to be approximately $200,000.

     The Management Services Agreement provides that the Orthodontic Affiliate
will utilize the facility and the Company's services for a period of 20 years,
with two ten year extensions. While each Management Services Agreement will be
negotiated based on specific circumstances, the management fees charged will
typically be 65% to 75% of the Orthodontic Affiliate's gross income, which is
expected to be sufficient to pay all of the MSO's expenses and provide a return
on the Company's investment. A portion of the profits, if any, exceeding an
agreed upon profit target will generally be shared with the Orthodontic
Affiliate. At the retirement, disability or death of the Affiliated
Orthodontist, the Company will locate a replacement Affiliated Orthodontist to
purchase the Orthodontic Affiliate and assume the Management Services Agreement.
 

Plan of Operation

     Omega's financial results for the period from August 30, 1996 (inception)
to December 31, 1996 relate to its initial organization and establishment of
infrastructure. During this period, Omega provided management consulting
services to 10 orthodontic practices on a fee for services basis. The revenue
and expenses are associated with the management consulting services provided by
Omega during that period.

     Omega has executed Affiliation Agreements with the seven Initial
Orthodontic Affiliates. Pursuant to those agreements, Omega will acquire the
equity interests in the MSOs of the seven Initial Orthodontic Affiliates (except
in the case of one sole proprietorship where it will acquire certain assets of
such proprietorship) concurrently with the closing of this Offering. Each of the
Initial Orthodontic Affiliates is operated with one orthodontist, who is
typically supported by a staff of three dental assistants and three office
personnel. The seven Initial Orthodontic Affiliates generated gross revenues for
the year ended December 31, 1996 of approximately $4.6 million. Gross revenues
for each Initial Orthodontic Affiliate for that year ranged from a low of
approximately $390,000 to a high of approximately $975,000.

     In consideration for acquiring the Initial MSOs, the Company will pay the
aggregate of approximately $2.1 million in cash, issue an aggregate of
approximately $794,000 in notes bearing interest at 8.5%, issue an aggregate of
315,655 shares of Common Stock valued at the initial public offering price per
share and grant an option to acquire 83,333 shares of Common Stock (assuming an
initial public offering price per share of $6.00) at an exercise price equal to
the initial public offering price per share.

                                       20

<PAGE>


     The Company expects to show a significant loss from operations for the six
month period ending June 30, 1997 due primarily to compensation paid to two
consultants. On April 28, 1997, each of Dr. Glovsky, the Chairman of the Board
of the Company, and Mayflower, a private banking firm, received 225,000 shares
of Common Stock for consulting services to Omega and will receive approximately
$421,000 of cash payments over three years beginning in January 1998. See
"Certain Transactions." The Company will recognize a non-recurring compensation
expense reflecting delivery of such shares and these payment obligations in
April 1997 of approximately $2.2 million. This expense is comprised of
approximately $1.4 million attributable to the Common Stock and an aggregate of
approximately $842,000 attributable to the payment obligation.

     At the end of the 12 months following this Offering, the Company intends to
be affiliated with approximately 31 Orthodontic Affiliates. In addition to the
Affiliation Agreements with the seven Initial Orthodontic Affiliates, Omega has
executed non-binding letters of intent to affiliate with four other orthodontic
practices. The ability of the Company to achieve its expansion plans will depend
upon a number of factors, including (i) the Company's ability to attract
orthodontists to affiliate with the Company, the availability of suitable
markets and the Company's ability to obtain suitable locations within those
markets; (ii) the Company's ability to locate existing practices for
affiliation, affiliate with such practices on favorable terms and successfully
integrate the affiliated operations into the Company's existing operations; and
(iii) the availability of adequate financing to affiliate with orthodontic
practices. A shortage of available orthodontists with the skills and experience
required by the Company would have a material adverse effect on the Company's
expansion plans. There can be no assurance that the Company's expansion strategy
will be successful, that modifications to the Company's strategy will not be
required or that the Company will be able to manage effectively and enhance the
profitability of its Orthodontic Affiliates. The accompanying pro forma
financial statements do not include costs anticipated to be incurred in
connection with this expansion strategy.

     The acquisition of the equity interests in the Initial MSOs (and certain
assets of the sole proprietorship) will be accounted for by the Company using
the purchase method of accounting, which records as goodwill the excess of
purchase price over the fair market value of the net assets of the acquired
businesses. As of December 31, 1996, the Company's total pro forma assets were
approximately $6.7 million, of which approximately $4.8 million, or 71%, was
goodwill. Goodwill will be amortized on a straight-line basis over a 40 year
period.

     Substantially all of the goodwill on the Company's pro forma adjusted
balance sheet as of December 31, 1996 is related to acquiring the Initial MSOs.
The Company evaluates each acquisition and establishes an appropriate
amortization period based on the underlying facts and circumstances. Currently,
the Company uses 40 years consistent with the extended terms of the Management
Services Agreements. Subsequent to each acquisition, the Company will reevaluate
such facts and circumstances to determine if the related goodwill continues to
be realizable and if the amortization period continues to be appropriate.

     Amortization of the goodwill on the Company's pro forma adjusted balance
sheet as of December 31, 1996 will produce an annual amortization expense of
approximately $121,485. Affiliations with additional Orthodontic Affiliates
which result in the recognition of additional goodwill would cause amortization
expense to increase further. Although the net unamortized balance of goodwill on
the Company's unaudited pro forma balance sheet as of December 31, 1996 was not
considered to be impaired, any future determination that a significant
impairment has occurred would require the write-off of the impaired portion of
unamortized goodwill, which would have a material adverse effect on the
Company's business, financial condition and results of operations.

Unaudited Pro Forma Results of Operations

     The following discussion of the unaudited pro forma results of operations
of the Company and of the combined results of operations of the Initial
Orthodontic Affiliates should be read in conjunction with the Unaudited Pro
Forma Financial Statements and Notes thereto and the financial statements of
Omega and each of the Initial Orthodontic Affiliates included elsewhere in this
Prospectus.

     Practice Revenue. The pro forma revenue of the Company consists almost
exclusively of amounts to be earned under the Management Services Agreement. The
revenue included in the pro forma financial statements is that which would have
been earned based on the operating results of the Initial Orthodontic Affiliates
for the year ended December 31, 1996, assuming the Affiliation Agreements and
Management Service Agreements had been entered into on January 1, 1996. The pro
forma revenue of $4.6 million for the year ended December 31, 1996 is based on
the accrued gross revenue of the Initial Orthodontic Affiliates for the year
ended December 31, 1996.

                                       21

<PAGE>


     Orthodontists' Compensation. Pursuant to the Management Services
Agreements, the Orthodontic Affiliates retain the difference between the patient
revenue of the Orthodontic Affiliate and the management fee payable to the
Company. The Orthodontic Affiliates are responsible for paying certain expenses
directly, including salaries and benefits of the Affiliated Orthodontist and any
other practice providers, physician licensing fees, board certification fees,
professional liability insurance, certain professional education and legal and
professional fees. In addition, the Orthodontic Affiliate is entitled to a
portion of the profits, if any, exceeding an agreed upon profit target.

     Direct Practice Expenses.  The pro forma direct practice expenses for the
year ended December 31, 1996 reflect the direct practice expenses of the Initial
Orthodontic Affiliates which would have been payable by the Company under the
Management Services Agreement. The Company expects that direct practice expenses
will increase as the Company affiliates with additional Orthodontic Affiliates
but that direct practice expenses as a percentage of practice revenue will
decrease as the Company implements the Model at additional Orthodontic
Affiliates. Direct practice expenses include:

        Employee Costs. Includes all salaries, payroll taxes and fringe benefits
        of the dental assistants and office staff.

        Other Direct Costs. Includes dental and office supplies, laboratory
        costs, facilities and equipment.

        General and Administrative. All other operating expenses including
        advertising, repairs and maintenance, computer support, telephone,
        utilities, taxes and licenses.

        Bad Debt Expense. Reflects an allowance for possible uncollectible
        practice revenue.

        Depreciation and Amortization. Includes depreciation of leasehold
        improvements and equipment.

     Management Expenses. The pro forma management expenses for the year ended
December 31, 1996 reflect an estimate of a complete year of expenses that may be
incurred with the management of the seven Initial Orthodontic Affiliates and the
provision of limited management consulting services to non-affiliated
orthodontic practices. The pro forma expenses include certain costs associated
with operating as a publicly-traded company following this Offering. Pro forma
management expenses do not include the non-recurring compensation expense of
$2.2 million that the Company will recognize in April 1997. See "--Plan of
Operation." Also, pro forma management expenses do not include any costs for
travel, consulting or professional fees associated with the identification,
evaluation and integration of additional Orthodontic Affiliates which the
Company will incur in connection with the planned affiliation with up to 24
additional Orthodontic Affiliates. These costs may be substantial and may cause
the Company to incur operating losses. Moreover, pro forma management expenses
do not include the anticipated incremental costs of managing such additional
Orthodontic Affiliates as the related management fees are not included in the
pro forma revenues. Such costs may also be substantial and may vary according to
the operations of each new Orthodontic Affiliate. Management expenses include
the following:

        Employee and Consulting Costs. Includes the salaries of the President,
        the part-time Chief Financial Officer, and the part-time administrative
        assistant, fees for a full time practice consultant and the travel and
        incremental costs associated with the ongoing support of the seven
        Initial Orthodontic Affiliates.

        General and Administrative. Includes legal, auditing, insurance, rent,
        telephones and marketing costs.

     Income Taxes. Pro forma income taxes assume that the Company had operated
as a tax paying entity, subject to an effective combined statutory tax rate for
federal and state income taxes of 40%, increased by the non-deductible portion
of goodwill amortization.

Liquidity and Capital Resources

     Omega has experienced net losses, negative cash flow, a deficit in working
capital and an accumulated deficit since its inception. For the period from
August 30, 1996 (inception) to December 31, 1996, Omega incurred a net loss of
$232,112. Omega has generated limited revenues to date, and will not generate
sufficient revenues to cover expenses without consummation of this Offering and
the Acquisitions. The Company expects to show a significant loss from operations
for the six month period ending June 30, 1997 due primarily to compensation
earned by two consultants in April 1997. See "--Plan of Operation." At December
31, 1996, the Company had an accumulated deficit since inception of $232,112 and
a working capital deficit of $368,032.

                                       22

<PAGE>


     Omega has financed its operations to date from the sale of the Bridge
Notes. The Bridge Notes, which bear interest at the rate of 15% per annum
payable currently, are payable on the earliest of the closing of this Offering
or September 30, 1997. Omega sold the Bridge Notes in a private offering to a
limited number of persons meeting the definition of "accredited investor" under
the Securities Act. The Bridge Notes were offered in principal amounts of
$50,000 (subject to reduction at the discretion of Omega) and included a right
to receive, without additional consideration, 10,000 shares of Common Stock
(subject to a corresponding reduction) upon issuance of the Bridge Notes. During
September, October and November 1996 and February and April 1997, Omega sold
Bridge Notes in the aggregate principal amount of $875,000 and issued 175,000
shares of Common Stock in connection therewith. The Company plans to repay the
entire amount of principal and interest outstanding on the Bridge Notes with a
portion of the net proceeds of this Offering. See "Use of Proceeds."

     In connection with the Affiliation Agreements, the Company has committed,
contingent upon this Offering, to acquire the Initial MSOs. The Company will pay
approximately $2.1 million in cash, issue an aggregate of approximately $794,000
in notes bearing interest at 8.5% with interest only payable the first year and
the principal to be amortized over the next four years, issue an aggregate of
315,655 shares of Common Stock valued at the initial public offering price per
share and grant an option to acquire 83,333 shares of Common Stock (assuming an
initial public offering price per share of $6.00) at an exercise price equal to
the initial public offering price per share.

     The Company intends to affiliate with up to an additional 24 Orthodontic
Affiliates during the 12 months following the closing of this Offering. The
purchase price of each MSO is anticipated to average $600,000, with the cash
portion of the purchase price expected to average approximately $200,000. The
Company expects to finance this expansion through the use of approximately $5.0
million of the net proceeds from this Offering. See "Use of Proceeds."

     The Company will typically purchase the equity interests in the MSO that
holds certain assets of and is associated with an Orthodontic Affiliate with a
combination of cash, notes payable and Common Stock of the Company. The purchase
price and terms are determined by the Company on a case by case basis after due
diligence has been performed.

     The Company anticipates that capital expenditures during 1997 will relate
primarily to affiliations with additional Orthodontic Affiliates. It is
anticipated that funding for these purposes will be derived from the proceeds of
this Offering and cash flow from operations. Management believes that such
sources will be sufficient to fund the Company's cash requirements for at least
12 months following completion of this Offering. In the future, the Company will
seek to raise additional funds through borrowings or the issuance of debt or
equity securities. There can be no assurance that sufficient funds will be
available on terms acceptable to the Company, if at all.

                                       23

<PAGE>


                                   BUSINESS

     The Company provides management and marketing services to orthodontic
practices in the United States. Since its inception in August 1996, Omega has
provided these services on a fee for services basis to 10 orthodontic practices,
including four of the Initial Orthodontic Affiliates. Following this Offering,
the Company intends to offer its services primarily under an affiliate
relationship whereby it purchases the equity interests in the MSO that holds
certain assets of and is associated with an Orthodontic Affiliate and enters
into a long term Management Services Agreement with the Orthodontic Affiliate.
The Company has signed Affiliation Agreements with the seven Initial Orthodontic
Affiliates and letters of intent with four additional practices.

     Upon consummation of the Acquisitions, the Company will enter into
Management Services Agreements with the Initial Orthodontic Affiliates. Pursuant
to these Management Services Agreements, the Company will provide facilities,
support staff and supplies to the Initial Orthodontic Affiliates and will
institute a program of systems, methods and procedures the Company refers to as
the Omega Exceptional Practice Model. The Model is designed to increase the
Orthodontic Affiliate's profitability by focusing on and improving customer
service while simultaneously reducing costs and increasing operating efficiency.
 

     Omega seeks to affiliate with established orthodontic practices that Omega
believes have the potential for significant growth utilizing the Model. Omega
considers financial and operational factors that include the practice's gross
income, cost structure, existing treatment contracts, fee schedules, referral
rates and sources, health maintenance organization relationships, case starts,
appointments per day and average treatment times. Omega also evaluates
demographic factors that include the practice's location with respect to and the
average income levels and concentrations of families with children in the area.

     The Company's strategy is to (i) enter into Affiliation Agreements and
Management Services Agreements with established orthodontic practices that meet
the Company's criteria and (ii) achieve operating efficiencies and increased
profitability for each such practice through the implementation of the Model.
The Model is designed to permit the practice to meet or exceed patient
expectations (a) offering flexible payment plans, (b) scheduling convenient
appointment times, (c) ensuring that treatment is delivered on time, (d)
updating patients and their referring dentists regularly on treatment programs
and (e) training staff to anticipate and address patient needs.

     The Company will focus its initial marketing efforts on the practices of
the approximately 4,500 orthodontists over the age of 47 who the Company
believes are planning their transition to retirement. The Company believes it
can generally place a higher value on a mature practice than other potential
buyers, many of whom are recent orthodontic graduates. The Company believes that
this higher valuation, combined with consideration in the form of a combination
of cash, notes and the Company's Common Stock and the opportunity to delegate
managerial and marketing responsibilities to an experienced management team,
generally makes the Company an attractive alternative for orthodontists planning
their transition to retirement. The Company will also target younger
orthodontists who may want to merge their practices with the practice of an
orthodontist in transition or take over such a practice.

The Orthodontic Industry

     General. The annual market for orthodontic treatment and services is
estimated at $3.6 billion. Based on U.S. census data that indicates that the
number of children between the ages of five and 19 will increase by
approximately 10.4 million by the year 2000, the Company expects that the growth
in this population group will result in increased demand for orthodontic
services. The orthodontic marketplace is highly fragmented and consists of
approximately 9,000 practicing orthodontists, a significant majority of whom are
sole practitioners. Omega believes that many of the orthodontists in practice
today have excess patient capacity and lack the training and resources in
management and marketing techniques to fill that capacity effectively. It is
Omega's belief that less than two percent of the orthodontic practices in the
United States are presently managed by independent, professional management
service organizations and that an opportunity exists for the Company to market
and sell its services to the orthodontic practices that are not currently
managed by such organizations.

     The projected growth of the orthodontics market derives from several
demographic and economic factors. The number of patients of prime orthodontic
treatment age (12 years old) is projected to remain at a level that is 20%
higher in the ten years ending in 2002 than in the prior ten year period. Also,
although orthodontic treatment has been historically viewed as an expensive
elective, advances in practice methods and technologies have made it relatively
more affordable. As a result, orthodontic treatment is being sought by a
broadening segment of American society.

                                       24

<PAGE>


     Orthodontic Practice Dynamics.  Although there exists a large and growing
demand for orthodontic services in the United States, the Company believes that
the orthodontic industry is presently ill-prepared to meet that demand.
Orthodontists, the vast majority of whom are sole practitioners, are often
highly skilled clinicians but generally are not trained in marketing themselves
as professional service providers. Most rely on referrals from other dentists
and from current or past patients. Accordingly, the Company believes that
achieving sustainable growth through referrals requires both clinical excellence
and a patient focus that emphasizes value, flexibility and efficiency.

     In order to increase profitability, the Company believes that orthodontists
must improve their management and marketing techniques. Unlike many other
medical and dental specialties, orthodontics involves treatment delivered over a
period of two to three years for a fixed fee. Much of the treatment can be
provided efficiently by the orthodontist delegating certain clinical and
communications tasks to trained assistants. The Company believes that creative
management and effective delegation would allow the orthodontist to reduce
treatment costs per patient. In addition, the Company believes that the well
managed orthodontic practice would also be able to handle a larger patient base,
and, with a patient centered emphasis on the quality and efficiency of the
services it offers, should be able to build that base through professional and
patient referrals. As a result, the Company believes that an orthodontic
practice with a qualified and capable orthodontist operating under a
well-designed efficient schedule and utilizing professional management and
marketing practices is capable of enhancing its profitability.

     Market for Orthodontic Practices.  The value of orthodontic practices in
the United States has fallen for the past several years. The number of potential
sellers, generally orthodontists approaching retirement age, is relatively large
compared to the potential purchasers. This downward pressure on prices for
orthodontic practices results primarily from the fact that approximately 4,500,
or 50%, of the practicing orthodontists in the United States are over the age of
47. The Company believes that many are looking to make a transition out of
active practice while realizing as much value as possible from the goodwill they
have built up over their years in practice.

     State laws governing the practice of dentistry and its specialties and the
shrinking number of orthodontic graduates intending to practice in the United
States have combined to limit the number of potential purchasers of orthodontic
practices. State dental practice statutes and professional codes generally
provide that only orthodontists may own, operate or control an orthodontic
practice. These restrictions have functioned to depress the market for
orthodontic practices and have inhibited the development of professional
management in the industry.

     Another major factor in limiting the value of orthodontic practices is the
historic oversupply of orthodontists in the United States which has reduced the
number of recent orthodontic graduates. In addition, many of the more recent
graduates are foreign students who plan to return to their own countries. The
orthodontic graduates who seek to buy a practice generally have student loans
and limited financial resources. As a result, the average purchase price for an
orthodontic practice has fallen from roughly one year's gross revenues to
approximately 70% of that number. In addition, the selling orthodontists often
must finance the purchase by accepting a note for a significant part of the
purchase price and, in order to ensure that the practice performs well enough to
service the debt, often must stay involved in the management and marketing of
the practice.

Business Strategy

     The Company's strategy has two principal components. First, the Company
identifies established orthodontic practices that it believes have potential for
significant growth utilizing the Model and offers to affiliate with and manage
those practices. Second, once an affiliate relationship is established, the
Company and the Affiliated Orthodontist (who may or may not be the selling
orthodontist) and the orthodontist's staff implement the Model in order to
achieve operating efficiencies and increase profitability for the practice.

     Identifying Potential Affiliations.  The Company's success will largely
depend upon the quality and quantity of orthodontic practices that it can
attract to affiliate with the Company. The Company selects practices to consider
affiliating with which are operated by orthodontists who are qualified members
of the American Association of Orthodontists. Management believes that the
Company has the resources to identify a significant number of potential
affiliates that meet the Company's criteria for affiliation. Although the
Company has been in operation for less than a year, the members of the senior
management team responsible for operations, Messrs. Schulhof, Bellavia and
Elliott, each has been involved in the orthodontic industry for 12 or more
years. Through their extensive presentations at orthodontic seminars and active
consulting practices to the orthodontic industry, the Company's senior
management team has relationships with practicing orthodontists throughout the
country. The Company has

                                       25

also established a program of regular trade journal advertising, and Mr.
Schulhof, in conjunction with Messrs. Bellavia and Elliott, has written a series
of articles for orthodontic trade journals that outline the Model and its
benefits for the practicing orthodontist.

     Once the Company identifies a potential affiliate, the Company conducts a
comprehensive analysis of the practice, including a thorough financial and
operational review and evaluation of staff, facilities, equipment and systems.
Initially, an estimate of the current value of the practice is calculated based
on the practice's gross income, net profit and new treatment contracts written
during the prior twelve months. The Company evaluates the practice's capacity
for improvement under the Model by analyzing (i) the number of new patient
exams, treatment starts, patients in active treatment and patients seen per day,
(ii) the fees charged for different treatments, (iii) the costs incurred by the
practice for employees, facilities, supplies and laboratory work and (iv) the
number of treatment chairs and dental and clinical assistants and the square
footage of office space employed by the practice. Also, current staff are
interviewed to determine their suitability for and commitment to the practice,
and facilities and equipment are reviewed to ensure that they will support a
larger and growing practice without significant additional cost. Finally, the
practice's current systems for starting new patients, reviewing treatment
programs, scheduling, communicating with patients and referral sources,
marketing and controlling expenses, and the cost of upgrading or replacing the
systems, are analyzed.

     The Company seeks practices that have the capacity to increase their
profitability initially through improved performance on existing patient bases
rather than through immediately increasing new patient exams. The Company
generally requires that practices demonstrate the potential to grow
approximately 40% with a relatively small increase in new patient exams.
Practices that have developed strong professional referral relationships and
have attractive locations and facilities are preferred over those that rely on
mass marketing techniques and health maintenance organization relationships to
grow.

     The Company also evaluates demographic factors affecting the practice.
Practices located where there are significant concentrations of families with
young children are attractive, particularly when the families have higher
incomes than the national average and these populations are stable or growing.
To date, the Company has focused its efforts on locating practices in the South
or far West of the United States. The seven Initial Orthodontic Affiliates
maintain an aggregate of eight offices, and such offices are situated in the
following locales: Goodyear and Bullhead City, Arizona; Huntington Beach and
Woodland Hills, California; Colorado Springs, Colorado; Champaign, Illinois;
Elko, Nevada and Austin, Texas.

     If the practice satisfies the Company's criteria for an affiliation, an
offer is made for the practice to affiliate with the Company. The Company
outlines proposed financial terms of the affiliation, including the Company's
valuation of the practice and the amount of cash, notes and shares of the
Company's Common Stock that the Company proposes to pay to acquire the equity
interests in the MSO associated with the practice. Once the basic business terms
of the affiliation are agreed to, the parties proceed to execute an Affiliation
Agreement and the related Management Services Agreement. The Company will pay,
on average for each of the Initial Orthodontic Affiliates, a combination of
approximately $300,000 in cash and $115,000 in five year notes bearing interest
at 8.5% and issue approximately 45,000 shares of the Common Stock if valued at
the initial public offering price per share of the Common Stock. The Company
plans to enter into Affiliation Agreements and Management Services Agreements
with up to an additional 24 Orthodontic Affiliates during the 12 months
following the closing of this Offering.

     Implementing the Omega Exceptional Practice Model.  The Model is patient
centered and designed to promote customer service and increase the
orthodontist's productivity while permitting the orthodontist to deliver quality
orthodontic treatment. The Model focuses the orthodontic team on understanding
patient expectations and provides the orthodontic team with the training,
systems and other tools necessary to meet or exceed those expectations. The
Model will generally be implemented in a practice over a period of 12 months and
involve the active participation of the Company's professional staff, the
Affiliated Orthodontist and his or her staff and a practice facilitator assigned
by the Company to oversee the entire installation, monitor its progress and
provide follow-up support.

     Customer service permeates all aspects of the Model. The Company intends to
provide a scheduling system that offers patients a wide choice of appointment
times, including night and weekend appointments. The system will also carefully
plan the Affiliated Orthodontist's time so that the patient is seen on schedule
and the work performed within the allotted appointment time. The Company intends
to offer flexible payment plans that meet

                                       26

<PAGE>

the varying financial situations of the patients and plans to review insurance
benefits and credit issues with the patient in advance so that patients coming
to a first exam will have sufficient information at the end of that exam to
commit to the proposed plan of treatment.

     The Company believes that good communication between patients and the
orthodontic team is essential to building successful relationships and
developing customer satisfaction. The Company will train the Affiliated
Orthodontist and his or her staff in interpersonal skills and communication
techniques and will carefully plan and script patient interactions so that the
orthodontic team is attuned to patient needs and can handle their questions
accurately and efficiently. The staff will be instructed to make courtesy calls
to patients after long or particularly difficult appointments to inquire about
patient comfort and answer questions. In addition, the Company will use
computerized analysis and video imaging to provide the patient with a clear
understanding of the proposed treatment, including all planned tooth and jaw
movements, and its intended results.

     In order to enhance the total dental care the patient receives and to
improve the Orthodontic Affiliate's professional referral sources, the Model
also encourages frequent communication between the orthodontic team and the
referring dentist. Automated diagnostic letters that include a treatment status
report and video images of the patient will be periodically delivered to the
referring dentist. Brief seminars on current orthodontic developments are
planned from time to time at the Orthodontic Affiliate's office in order to keep
referring dentists and their staffs informed and to promote opportunities for
professional and staff interaction. By encouraging the close integration of
orthodontic and general dental services, the Model promotes improved overall
dental care for the patient and fosters strong relationships with the general
dentists for future referrals.

     The Company believes that a more productive practice also serves the
interest of the orthodontic patients. In order to increase the Orthodontic
Affiliate's productivity, the Model requires the orthodontic team to establish
operational goals, such as increasing the number of treatment starts, percentage
of patients seen on time and the dollars generated per minute of chair time and
reducing the chair time required to treat different types of cases. The
orthodontic team also sets financial and quality goals for the practice. In
order to assist the orthodontic team in accomplishing these goals, the Company
will produce written policies and procedures for the orthodontic team to adopt
and follow and will either upgrade the practice's present systems or install a
new, computerized operational and financial reporting system so that progress
can be measured regularly.

     The Company believes that implementation of the Model generally should be
accomplished over a 12 month period. The program will be overseen by one of the
Company's experienced practice facilitators who coordinates the efforts of the
orthodontic team and the Company. The practice facilitator will visit the
Orthodontic Affiliate monthly during this period to train the orthodontic team,
install systems and programs and audit and debug their performance. By the end
of the first 12 months, the Orthodontic Affiliate generally will have completed
the following tasks: (i) established a new staff organizational structure; (ii)
installed a communication and marketing system; (iii) installed a sophisticated
scheduling system to increase treatment productivity; (iv) instituted a new,
flexible fee and payment program; (v) installed a new or upgraded financial and
operational reporting system; (vi) conducted staff relationship training; (vii)
conducted initial and final patient surveys; and (viii) installed a patient
communication and treatment completion review program.

Agreements with Affiliated Orthodontists

     The Company plans to affiliate with orthodontic practices through a series
of contractual arrangements. Initially, the Company and an Affiliated
Orthodontist will enter into an Affiliation Agreement through which the Company
will acquire the equity interests in the MSO associated with the Affiliated
Orthodontist's practice. (The Company may cause a wholly-owned subsidiary to
acquire the equity interests in the MSO to reduce adverse tax consequences in
certain cases.) The Affiliated Orthodontist, who generally practices through and
holds the practice assets in a professional corporation, will convert that
entity into a general corporation (the MSO) and create a new professional
corporation through which the Affiliated Orthodontist will continue to provide
orthodontic care (the Orthodontic Affiliate). The Company acquires the equity
interests in the MSO, and the Affiliated Orthodontist causes the Orthodontic
Affiliate to enter into a long-term Management Services Agreement with the
Company.

     Through the Management Services Agreement, the Company provides practice
management and marketing services, facilities and non-professional personnel to
the Orthodontic Affiliate for a monthly fee. In order to provide for an orderly
transition in the event that the Management Services Agreement is terminated or
expires or the Affiliated Orthodontist ceases practice with the Orthodontic
Affiliate, the parties enter into a Stock Put/Call Option

                                       27

<PAGE>

and Successor Designation Agreement (the "Put/Call Agreement"). This agreement
creates for the Affiliated Orthodontist certain rights and obligations to
repurchase the practice assets held by the Company in the event that the
Management Services Agreement is terminated and grants the Company certain
rights to designate a successor orthodontist to purchase the stock of the
Orthodontic Affiliate when the Affiliated Orthodontist ceases practice through
retirement, death, disability or in other enumerated cases.

     Affiliation Agreement.  The Affiliation Agreement is the mechanism through
which the Company acquires the equity interests in the MSO of the Orthodontic
Affiliate, typically in exchange for a combination of cash, a promissory note
and shares of Common Stock of the Company. The completion of the acquisition
under the Affiliation Agreement is subject to certain conditions, including,
without limitation, that there has been no material adverse change to the
Orthodontic Affiliate between the time the Affiliation Agreement is signed and
the transaction is closed and that the Orthodontic Affiliate and the Company
have entered into the Management Services Agreement and the Put/Call Agreement.
The closing of the Acquisitions is further conditioned on the completion of this
Offering.

     Management Services Agreement.  Pursuant to the Management Services
Agreement, the Company provides the Orthodontic Affiliate comprehensive
management, financial and marketing services and facilities, equipment and
support personnel required by the Orthodontic Affiliate to operate its clinical
orthodontic practice. The Company is appointed the sole and exclusive business
manager of the Orthodontic Affiliate. In addition to providing facilities,
equipment and support services, the Company undertakes all purchasing, payment,
billing, collection and payroll functions for the Orthodontic Affiliate and
facilitates the implementation of the Model.

     The Orthodontic Affiliate is solely responsible for and has complete
control and supervision over the professional aspects of its practice, as well
as the provision of all professional services, including, without limitation,
the selection of course of treatment for a patient, procedures or materials to
be used as part of such treatment and the manner in which such treatment is
carried out. The Orthodontic Affiliate has sole authority to direct the
business, professional and ethical aspects of its practice. It makes all
professional hiring decisions, renders patient care, and keeps all patient
dental records. The Orthodontic Affiliate is also responsible for entering into
an employment agreement, including non-competition provisions, with each
orthodontist engaged by it, including the Affiliated Orthodontist, and paying
all salaries for dental professionals, professional licensure and board
certification fees and professional liability insurance premiums.

     The Management Services Agreement has an initial term of twenty (20) years
and is renewable for two, successive ten (10) year periods. During the initial
term and any renewal term, the Management Services Agreement may be terminated
by the Company or the Orthodontic Affiliate only for "cause," which includes the
bankruptcy of or a material default by the other party. In exchange for the
performance of its duties and obligations under the Management Services
Agreement, the Company receives a monthly management fee. The fee, which varies
somewhat from practice to practice, is generally 65% to 75% of the Orthodontic
Affiliate's gross collections for the period. From the monthly fee, the Company
pays all of its expenses in providing services to the Orthodontic Affiliate,
including, without limitation, the salaries and benefits of the Company's
employees, the costs of any consultants, corporate overhead, lease obligations
and taxes.

     Put/Call Agreement.  The Put/Call Agreement governs the dissolution of the
affiliation between the Orthodontic Affiliate and the Company, whether caused by
a termination or expiration of the Management Services Agreement or as a result
of the cessation of practice by the Affiliated Orthodontist. In the case of a
termination or expiration of the Management Services Agreement, the Orthodontic
Affiliate may be required to repurchase certain assets of the Company (when the
termination is initiated by the Company) or may have the right to repurchase
such assets (when the termination is initiated by the Orthodontic Affiliate).
When the Affiliated Orthodontist ceases practicing with the Orthodontic
Affiliate, whether as a result of retirement, death, disability or other reason,
the Company typically has the option to designate a successor orthodontist to
purchase the Orthodontic Affiliate from the Affiliated Orthodontist in order to
ensure that the Orthodontic Affiliate continues to operate and to perform its
obligations under the Management Services Agreement. The Company may choose not
to exercise this option where the Affiliated Orthodontist proposes to sell the
Orthodontic Affiliate to another orthodontist previously approved by the Company
to be the Affiliated Orthodontist's successor in the ownership of the
Orthodontic Affiliate.

                                       28

Competition

     The business of providing orthodontic services is highly competitive in
each of the markets in which the Company operates. Each of the Company's
Orthodontic Affiliates faces competition from orthodontists who maintain single
offices or operate a single satellite office, as well as from orthodontists that
maintain group practices or operate in multiple offices. The Orthodontic
Affiliates also compete with dentists who provide certain orthodontic services.
The provision of orthodontic services by such dentists has increased in recent
years.

     At this time, the Company believes that there is one publicly-traded
company, Orthodontic Centers of America, Inc. ("OCA"), actively competing in the
orthodontic practice management market and that there are several other
companies participating in the market. OCA and the other companies are
significantly larger and have greater financial, marketing and other resources
than the Company. The Company will compete with OCA and these other companies
both for expansion into new affiliate practices and for patients. Management,
however, believes the Company appeals to a different segment of the orthodontic
services market than OCA and the other companies.

     In addition, there are several companies pursuing strategies similar to the
Company in other segments of the health care industry and additional companies
with similar objectives may enter the Company's markets and compete with the
Company. If a great number of competitors enter the orthodontic practice
management market, it could drive up the purchase price of orthodontic practices
adversely and affect the Company's expansion strategy. There can be no assurance
that the Company will be able to compete effectively.

Government Regulation

     The field of orthodontics is highly regulated, and there can be no
assurance that the regulatory environment in which the Company operates will not
change significantly in the future. In general, regulation of health care
companies is increasing.

     Every state imposes licensing requirements on orthodontists and on
facilities and services operated by orthodontists. In addition, federal and
state laws regulate health maintenance organizations and other managed care
organizations for which orthodontists may be providers. In connection with the
entry into new markets, the Company and its Affiliated Orthodontists may become
subject to compliance with additional regulations.

     The operations of Orthodontic Affiliates must meet federal, state and local
regulatory standards in the areas of safety and health. Based on its familiarity
with the operations of the Initial Orthodontic Affiliates and the activities of
the Affiliated Orthodontists, management believes that the Initial Orthodontic
Affiliates are in compliance in all material respects with all applicable
federal, state and local laws and regulations.

     The laws of many states prohibit orthodontists from splitting fees with
non-orthodontists and prohibit non-orthodontic entities (such as the Company)
from practicing dentistry, including orthodontics, and from employing
orthodontists or, in certain circumstances, orthodontic assistants. The laws of
some states prohibit advertising of orthodontic services under a trade or
corporate name and require that all advertising be in the name of the
orthodontist. A number of states also regulate the content of advertisement of
orthodontic services and the use of promotional gift items. A number of states
limit the ability of a non-licensed dentist or non-orthodontist to own equipment
or offices used in an orthodontic practice. Some of these states allow leasing
of equipment and office space to an orthodontic practice, under a bona-fide
lease, if the equipment and office remain in the complete care and custody of
the orthodontist. Management believes, based on its familiarity with the
operations of the Orthodontic Affiliates, the activities of the Company's
Affiliated Orthodontists and applicable regulations, that the Company's current
and planned activities do not constitute the prohibited practices contemplated
by these statutes and regulations. There can be no assurance, however, that
future interpretations of such laws, or the enactment of more stringent laws,
will not require structural and organizational modifications of the Company's
existing relationships with its Affiliated Orthodontists or the operation of the
Orthodontic Affiliates. In addition, statutes in some states could restrict
expansion of Company operations in those jurisdictions.

     The Company regularly monitors developments in laws and regulations
relating to dentistry. The Company may be required to modify its agreements,
operations and marketing from time to time in response to changes in the
business and regulatory environment. The Company plans to structure all of its
agreements, operations and marketing in accordance with applicable law, although
there can be no assurance that its arrangements will not be successfully
challenged or that required changes may not affect operations or profitability.

Employees

     At March 31, 1997, the Company had five employees and utilized ten
independent contractors to assist with certain corporate functions and to
provide consulting services to orthodontic practices. After consummation of the
Acquisitions, the Company expects to employ approximately 45 employees,
approximately evenly split between clinical and clerical employees. None of the
Company's employees are represented by a collective bargaining agreement. The
Company considers its relationship with its employees to be satisfactory.

Facilities

     The Company does not hold any leases for corporate facilities. In
connection with consummating the Acquisitions, the Company expects to lease an
average of 1,800 square feet of office space for each of the seven Initial
Orthodontic Affiliates. The Company expects that the typical lease for office
space will be for a term of approximately five years and generally provides for
renewal options for additional years.

     Following completion of this Offering, the Company intends to establish and
staff an office in Massachusetts for its financial operations. The Company
expects to lease office space and maintain its financial records in
Massachusetts.

Insurance

     The provision of orthodontic services entails an inherent risk of
professional malpractice and other similar claims. Although the Company does not
influence or control the practice of dentistry by the Affiliated Orthodontists
or have responsibility for compliance with certain regulatory and other
requirements directly applicable to Orthodontic Affiliates, the contractual
relationship between the Company and the Orthodontic Affiliates may subject the
Company to medical malpractice actions. There can be no assurance that claims,
suits or complaints relating to services and products provided by Orthodontic
Affiliates will not be asserted against the Company in the future. The
availability and cost of professional liability insurance has been affected by
various factors, many of which are beyond the control of the Company. The cost
of such insurance to the Orthodontic Affiliates may have an adverse effect on
the Company's operations.

     The Management Services Agreements will require the Orthodontic Affiliates
to maintain, at their expense, professional liability insurance for themselves
and each orthodontist employed by or otherwise providing orthodontic services
for the Orthodontic Affiliate in the minimum amount of $500,000 per occurrence
and $1,000,000 in the aggregate. In addition, each Orthodontic Affiliate will
undertake to comply with all applicable regulations and requirements, and the
Company will be indemnified under the Management Services Agreements for claims
against the Company arising in connection with actions by the Orthodontic
Affiliates. The Company has applied for general liability insurance for itself
and will require that it be named as an additional insured party on the
professional liability insurance policies of the Orthodontic Affiliates pursuant
to the Management Services Agreement. The Company does not maintain professional
liability insurance for itself.

     The Company maintains other insurance coverages including property,
workers' compensation and directors and officers liability insurance which
Management considers to be adequate for the size of the Company and the nature
of its business.

Litigation

     The Company does not have pending any litigation that, separately or in the
aggregate, if adversely determined, would have a material adverse effect on the
Company. The Company and its Orthodontic Affiliates may, from time to time, be
party to litigation or administrative proceedings which arise in the normal
course of business.

Affiliates and negotiating and closing Affiliation Agreements with such
practices. He will be paid monthly according to the following fee schedule: a
one time fee of $2,500 for each orthodontic practice that becomes an Orthodontic
Affiliate (other than the Initial Orthodontic Affiliates) in that month and,
beginning in the first month after the Company has an aggregate of 15
Orthodontic Affiliates (including

                                       32

<PAGE>

the Initial Orthodontic Affiliates), $5,000 per month, up to a maximum fee of
$60,000 in the first 12 months after the agreement becomes effective. At the end
of the first 12 months, the Company will review the workload of Dr. Glovsky
under the agreement and propose a revised fee schedule for the remainder of the
term of the agreement. If the parties cannot agree on a revised fee schedule,
Dr. Glovsky shall continue to receive fees based upon the initial fee schedule.

     Omega has also entered into a consulting agreement with LMG which became
effective on May 1, 1997 and provides that LMG shall render accounting and
financial consulting services to the Company and shall make Mr. Mulherin, a

Financial Officer. The initial term of the agreement is three years, and such
term will be extended automatically on May 1, 2000 and on each May 1 thereafter
for an additional year, unless either party gives notice of termination prior to
such extension. LMG will be paid a monthly fee of $5,000 until the later of
November 1, 1997 or the first month after the Company has an aggregate of 15
Orthodontic Affiliates (including the Initial Orthodontic Affiliates) and a
monthly fee of $10,000 thereafter for the term of the agreement. In addition,

Plan to acquire 150,000 shares of the Company's Common Stock at an exercise
price equal to the initial public offering price per share of the Common Stock.
The Company has also agreed to indemnify LMG against certain liabilities that
may arise in connection with the services to be rendered by LMG under the
agreement.

Executive Compensation

     No officer or director salary and bonus exceeded $100,000 during the period
from August 30, 1996 (inception) to December 31, 1996. The Company did not grant
any restricted stock awards, options or stock appreciation rights or make any
long-term incentive plan payouts during such period, nor did any of the
executive officers own options or stock appreciation rights during the period.
The Company has no defined benefit or actuarial plans covering employees of the
Company.

     The Company has obtained key man life insurance providing coverage for the
Company on the life of Mr. Schulhof in the amount of $1.0 million.

Employment Agreements

     Omega has entered into employment agreements (individually, an "Employment
Agreement" and collectively, the "Employment Agreements") with each of Mr.
Schulhof, Dr. Bellavia and Mr. Elliott (collectively, the "Executives"). Mr.
Schulhof's Employment Agreement became effective January 1, 1997 and provides
that he is employed as the President and Chief Executive Officer of the Company.
The initial term of Mr. Schulhof's Employment Agreement is three years, and such
term will be extended automatically on January 1, 2000 and on each January 1
thereafter for an additional year, unless Mr. Schulhof receives notice of
termination prior to such extension. Mr. Schulhof is paid an annual base salary
of $120,000, which amount is subject to annual review, and bonuses, the amounts
of which are determined by the Compensation Committee. Mr. Schulhof also has the
use of a company car or, at his election, will be paid an automobile allowance
of $700 per month.

     Dr. Bellavia's Employment Agreement will become effective upon the closing
of this Offering and provides that he will be employed as the Director of
Affiliate Programs of the Company. The initial term of Dr. Bellavia's Employment
Agreement is three years, and such term will be extended automatically on the
third anniversary date of the effectiveness and on each anniversary date
thereafter for an additional year, unless either party receives notice of
termination prior to such extension. Dr. Bellavia initially will be paid monthly
according to the following fee schedule: (i) a one time fee of $7,500 for each
Orthodontic Affiliate (other than the Initial Orthodontic Affiliates) in which
he initiates the implementation of the Model in that month and (ii) a fee of
$208.33 for each Orthodontic Affiliate operating under the Model in that month.
He will receive a monthly advance against these fees of $10,000, which advance
will be reviewed quarterly by the Company and, to the extent it exceeds the fees
earned for that quarter, the advance amount for the next quarter will be reduced
by an equal amount. Beginning in the first month after the Company has 15
Orthodontic Affiliates (including the Initial Orthodontic Affiliates), the
Company shall cease paying Dr. Bellavia according to this fee schedule.
Thereafter, Dr. Bellavia's Employment Agreement provides for a base salary of
$10,000 per month, which amount is subject to annual review, and bonuses, the
amounts of which are determined by the Compensation Committee.

     Mr. Elliott's Employment Agreement will become effective upon the closing
of this Offering and provides that he will be employed as the Director of
Professional Relations and Staff Development of the Company. The initial term of
Mr. Elliott's Employment Agreement is three years, and such term will be
extended automatically on the third anniversary date of the effectiveness and on
each anniversary date thereafter for an additional year, unless either party
receives notice of termination prior to such extension. Mr. Elliott initially
will be paid monthly according to the following fee schedule: (i) a one time fee
of $2,500 for each orthodontic practice that becomes an Orthodontic Affiliate
(other than the Initial Orthodontic Affiliates) in that month, (ii) a fee of
$1,250 per day per seminar conducted by Mr. Elliott for an Orthodontic Affiliate
in that month and (iii) a fee of $300 for each Orthodontic Affiliate to which
Mr. Elliott provides consulting services in that month. He will receive a
monthly advance against these fees of $10,000, which advance will be reviewed
quarterly by the Company and, to the extent it exceeds the fees earned for that
quarter, the advance amount for the next quarter will be reduced by an equal
amount. Beginning in the first month after the Company has an aggregate of 15
Orthodontic Affiliates (including the Initial Orthodontic Affiliates), the
Company shall cease paying Mr. Elliott according to this fee schedule.
Thereafter, Mr. Elliott's Employment Agreement provides for a base salary of
$10,000 per month, which amount is subject to annual review, and bonuses, the
amounts of which are determined by the Compensation Committee.

     The Employment Agreements may be terminated by the Company or the
respective Executives without cause with 90 days' prior written notice. Pursuant
to the terms of the Employment Agreements, each of the Executives has agreed not
to disclose the Company's confidential information and not to compete against
the Company during the term of his Employment Agreement and for a period of one
year thereafter, with certain exceptions.

     If the Executive suffers a "termination other than for cause" (as defined
in the Employment Agreements), including such a termination within 24 months
after a "change in control" (as defined in the Employment Agreements), the
Executive is entitled to receive his accrued salary, earned bonus compensation,
vested deferred compensation (other than plan benefits which will be payable in
accordance with the applicable plan) and other benefits through the date of
termination and severance payments of salary (at the rate payable at the time of
such termination) for the longer of 12 months or the remaining term of the
Employment Agreement. Each of the Executives may elect to receive from the
Company a lump sum severance payment equal to the present value of the flow of
cash from the severance payments of salary. In addition, each Executive is
entitled to an accelerated vesting of any awards granted to the Executive under
the Stock Option Plan. Notwithstanding the foregoing, the Company is not
required to pay any amount which is not deductible for federal income tax
purposes.

     If the Executive is terminated for "cause" (as defined in the Employment
Agreements), he is entitled to receive his accrued salary, earned bonus
compensation, vested deferred compensation (other than plan benefits which will
be payable in accordance with the applicable plan) and other benefits through
the date of termination, but shall receive no other severance benefits. Each of
the Executives may also be terminated if he dies or becomes disabled for a
period of 12 consecutive months. In the event of termination due to death or
disability, the Executive (or his estate) shall receive the same payments, but
no additional severance, except that, if the Executive becomes disabled, the
Company will maintain his insurance benefits for the remaining term of his
Employment Agreement.

Incentive Stock Plan

     Effective as of January 31, 1997, the Company adopted the Omega
Orthodontics Incentive Stock Plan (the "Stock Option Plan"). The Company had
reserved 300,000 of the authorized shares of Common Stock for issuance under the
Stock Option Plan. On April 28, 1997, the Stock Option Plan was amended to
increase the number of shares of Common Stock authorized for issuance under the
Stock Option Plan to 450,000. Unless terminated earlier, the Stock Option Plan
will terminate on January 30, 2007.

     Plan Administration; Eligibility. The Stock Option Plan is administered by
a committee consisting solely of two or more non-employee Directors (the
"Committee").

     The Committee has full power to select from among the persons eligible for
awards the individuals to whom awards will be granted, to make any combination
of awards to participants and to determine the specific terms of each award,
subject to the provisions of the Stock Option Plan. Persons eligible to
participate in the Stock Option Plan generally will be those employees and
directors of the Company and consultants to the Company who are responsible for
or contribute to the management, growth or profitability of the Company, as
selected from time to time by the Committee.

                                       34

<PAGE>


     Stock Options Granted to Employees. The Stock Option Plan permits the
granting of both incentive stock options ("Incentive Options") and non-qualified
stock options ("Non-Qualified Options") to Company employees. The exercise price
of each option shall be determined by the Committee but shall not be less than
100% of the fair market value for the shares on the date of grant. The term of
each option shall be fixed by the Committee and may not exceed 10 years from the
date of grant. The Committee shall determine at what time or times each option
may be exercised and, subject to the provisions of the Stock Option Plan, the
period of time, if any, after death, disability or termination of employment
during which options may be exercised. Options may also be made exercisable in
installments. Upon exercise of options, the option exercise price must be paid
in full (i) in cash or by certified or bank check or postal or express money
order, (ii) by delivery of shares of Common Stock valued at their fair market
value on the exercise date or (iii) partially in cash and partially in stock. To
qualify as Incentive Options, options must meet additional Federal tax
requirements, including limits on the value of shares subject to Incentive
Options which first become exercisable in any one year, and a shorter term and
higher minimum exercise price in the case of certain large stockholders.

     Stock Options Granted to Non-Employee Directors and Consultants. The Stock
Option Plan permits the granting of Non-Qualified Options to non-employee
Directors of the Company and to consultants to the Company. The exercise price
of such Non-Qualified Options shall be determined by the Committee and shall not
be less than the fair market value of the Common Stock on the date of grant. The
term of each option shall be fixed by the Committee and may not exceed 10 years
from the date of grant. The Committee shall determine at what time or times each
option may be exercised and, subject to the provisions of the Stock Option Plan,
the period of time, if any, after death, disability or termination of employment
during which options may be exercised. Options may also be made exercisable in
installments. Upon exercise of options, the option exercise price must be paid
in full (i) in cash or by certified or bank check or postal or express money
order, (ii) by delivery of shares of Common Stock valued at their fair market
value on the exercise date or (iii) partially in cash and partially in stock.

     Option Reloads. At the discretion of the Committee, options granted under
the Stock Option Plan to employees, directors or consultants may include a
so-called "reload" feature pursuant to which a participant exercising an option
by delivery of shares of Common Stock may be automatically granted an additional
option to purchase that number of shares equal to the number delivered to
exercise the original option.

     Stock Appreciation Rights. At the discretion of the Committee, options
granted under the Stock Option Plan to employees, directors or consultants may
include stock appreciation rights. Such stock appreciation rights are only
exercisable with their related stock options. Upon exercise of a stock
appreciation right a grantee shall be entitled to receive in cash or stock the
difference between the current fair market value of Common Stock and the
original exercise price of the underlying stock option. Stock appreciation
rights not exercised with the exercise of the underlying option will
automatically terminate.

     Restricted Stock and Unrestricted Stock. The Committee may also award
shares of Common Stock subject to such conditions and restrictions as the
Committee may determine ("Restricted Stock"). The purchase price, if any, of
shares of Restricted Stock shall be determined by the Committee. Recipients of
Restricted Stock must enter into a Restricted Stock award agreement with the
Company, in such form as the Committee determines, setting forth the
restrictions to which the shares are subject and the date on which the
restrictions will lapse and the shares become vested. The Committee may at any
time waive such restrictions or accelerate such dates. If a participant who
holds shares of Restricted Stock terminates the relationship with the Company
for any reason (including death) prior to the vesting of such Restricted Stock,
the Company shall have the right to require the forfeiture of such Restricted
Stock in exchange for the amount, if any, which the participant paid for them.
Prior to the vesting of Restricted Stock, the participant will have all rights
of a stockholder with respect to the shares, including voting and dividend
rights, subject only to the conditions and restrictions set forth in the Stock
Option Plan or in the Restricted Stock award agreement.

     The Committee may also grant shares (at no cost or for a purchase price
determined by the Committee) which are free from any restrictions under the
Stock Option Plan ("Unrestricted Stock"). Unrestricted Stock may be issued in
recognition of past services or other valid consideration.

     Performance Share Awards. The Committee may also grant awards ("Performance
Shares") entitling the recipient to receive shares of Common Stock upon the
achievement of individual or Company performance goals and such other conditions
as the Committee shall determine. A recipient of a Performance Share award must
enter

                                       35

<PAGE>

into an agreement setting forth the applicable conditions, as determined by the
Committee. Performance Shares may be awarded independently or in connection with
stock options or other awards under the Stock Option Plan.

     Adjustments for Stock Dividends, Mergers, Etc. The Committee shall make
appropriate adjustments in connection with outstanding awards to reflect stock
dividends, stock splits and similar events. In the event of a merger,
liquidation or similar event, the Committee in its discretion may provide for
substitution or adjustments.

     Amendments and Termination. The Board of Directors may at any time amend or
discontinue the Stock Option Plan. Moreover, no such amendment, unless approved
by the stockholders of the Company, shall be effective if it would cause the
Stock Option Plan to fail to satisfy any then applicable incentive stock option
rules under Federal tax law or applicable requirements of Rule 16b-3 under the
Securities and Exchange Act of 1934, as amended. Currently, the incentive stock
option regulations would require stockholder approval for an increase in the
maximum number of shares issuable pursuant to Incentive Options under the Stock
Option Plan, a modification in eligibility requirements under the Stock Option
Plan, a material increase in the benefits accruing to participants under the
Stock Option Plan or a material modification of the eligibility requirements
under the Stock Option Plan.

     At April 28, 1997, options with respect to 350,000 shares of Common Stock
have been granted to Dr. Bellavia, Mr. Elliott and LMG in the amounts of 50,000,
150,000 and 150,000 shares, respectively, at an exercise price equal to the
intial public offering price for the shares and 100,000 shares of Common Stock
were reserved for issuance pursuant to future grants under the Stock Option
Plan. The options granted to Mr. Elliott and LMG vest in three equal
installments on each of the first three anniversaries of the date of grant, and
the options granted to Dr. Bellavia vest fully on the first anniversary of the
date of grant.

                             CERTAIN TRANSACTIONS

     On August 31, 1996, Omega acquired OMEGA, LLC's orthodontic practice
management business and certain related assets, management contracts and
practice affiliation agreements in exchange for 1,050,000 shares of Omega's
Common Stock. Messrs. Schulhof, Glovsky, Grove and Bellavia, all of the then
directors of Omega, held 330 (27.7%), 75 (6.3%), 150 (12.6%) and 100 (8.4%) of
the membership points of OMEGA, LLC, respectively, at the time of the
transaction, and Mr. Schulhof was the sole manager of OMEGA, LLC.

     In connection with the acquisition by Omega of OMEGA, LLC's orthodontic
practice management business, Omega assumed OMEGA, LLC's rights and obligations
under an agreement with Dr. Glovsky, the Chairman of the Board of the Company,
and Mayflower, a private banking firm, whereby Dr. Glovsky and Mayflower (the
Consultants) agreed to provide certain consulting services to Omega. Under the
terms of the agreement, as amended and restated, 225,000 shares of Omega's
Common Stock were issued to each of the Consultants to be held in escrow pending
fulfillment of their consulting obligations to Omega. All of such shares were
released from the escrow on April 28, 1997 and delivered to the Consultants. In
addition, Omega agreed to make cash payments to the Consultants aggregating
$842,000 over three years beginning in January 1998. The Company is obligated 
to make quarterly payments to each of Dr. Glovsky and Mayflower on January 1,
April 1, June 1 and September 1, 1998, 1999 and 2000 of $67,500, $27,000 and
$10,800, respectively. Mayflower is a stockholder of the Company and holds 75
membership points of OMEGA, LLC, the Company's principal stockholder. See
"Principal Stockholders."

     During September 1996, Drs. Glovsky and Bellavia, both directors of the
Company and more than 5% owners of OMEGA, LLC, the Company's principal
stockholder, purchased $25,000 and $50,000, respectively, of the Bridge Notes
and received 5,000 and 10,000 shares, respectively, of the Company's Common
Stock in connection therewith. In April, 1997, Dr. Glovsky and Dr. Grove, also a
director of the Company, purchased an additional $5,000 and $25,000 of Bridge
Notes, respectively, and received an additional 1,000 and 5,000 shares of the
Common Stock, respectively, in connection therewith. The Company expects to
repay all of its Bridge Notes from the net proceeds of this Offering, including
the Bridge Notes held by Drs. Glovsky, Bellavia and Grove. See "Use of
Proceeds."

     The Company has entered into an Affiliation Agreement with Dr. Grove which
the Company expects to close concurrently with the closing of this Offering.
Pursuant to its agreement with Dr. Grove, a director of the Company, the Company
will acquire certain assets of Dr. Grove's orthodontic practice in exchange for
a cash payment of $333,567, a five year note in the original principal amount of
$333,567 bearing interest at 8.5% per year and amortizing over the last four
years of the term and 55,595 shares of the Company's Common Stock.

                           DESCRIPTION OF SECURITIES

General

     The Company is authorized to issue 9,500,000 shares of Common Stock, $.01
par value per share, and 500,000 shares of preferred stock, $.01 par value per
share (the "Preferred Stock"). As of April 30, 1997, 1,685,000 shares of Common
Stock were issued and outstanding and no shares of Preferred Stock were
outstanding. Upon consummation of this Offering, an aggregate of 3,800,655
shares of Common Stock will be outstanding and no shares of Preferred Stock will
be outstanding.

Common Stock

     Holders of Common Stock are entitled to one vote per share on all matters
submitted to a vote of stockholders. Stockholders have no right to cumulate
their votes in the election of directors. Accordingly, holders of a majority of
the shares of Common Stock entitled to vote in any election of directors may
elect all of the directors standing for election. Holders of Common Stock are
entitled to receive dividends and other distributions when, as and if declared
from time to time by the Board of Directors out of funds legally available
therefor. In the event of a voluntary or involuntary liquidation, dissolution or
winding up of the Company, the holders of Common Stock are entitled to share
ratably in all assets remaining after payment of liabilities, including all
distributions to holders of Preferred Stock having a liquidation preference over
the Common Stock.

Preferred Stock

     The Board of Directors has the authority, without any further vote or
action of the stockholders of the Company, to issue shares of the Preferred
Stock in one or more series and to determine the relative rights and preferences
of any such shares, including dividend rights, conversion rights, voting rights,
terms of redemption, liquidation preferences, sinking fund terms and the number
of shares constituting any series or the designation of such series without any
further vote or action by the stockholders. The issuance of Preferred Stock
could adversely affect the voting power of holders of Common Stock and the
likelihood that such holders will receive dividend payments and payments upon
liquidation and could have the effect of delaying, deferring or preventing a
change in control of the Company. The Company has no present plan to issue any
shares of Preferred Stock.

Warrants

     The following is a brief summary of certain provisions of the Warrants, but
such summary does not purport to be complete and is qualified in all respects by
reference to the actual text of the Warrant Agreement between the Company and
Continental Stock Transfer & Trust Company (the "Warrant Agent"), a copy of
which has been filed as an exhibit to the Registration Statement of which this
Prospectus is a part. See "Additional Information."

     Exercise Price and Terms.  Each Warrant entitles the registered holder
thereof to purchase, at any time commencing                , 1997 [six (6)
months after the date of this Prospectus] until          , 2002 [five years
after the date of this Prospectus], one share of Common Stock at a price of
$         per share [110% of the initial public offering price per share of
Common Stock], subject to adjustment in accordance with the anti-
dilution and other provisions referred to below. The holder of any Warrant may
exercise such Warrant by surrendering the certificate representing the Warrant
to the Warrant Agent, with the subscription form thereon properly completed and
executed, together with payment of the exercise price. No fractional shares will
be issued upon the exercise of the Warrants. The exercise price of the Warrants
bears no relationship to any objective criteria of value and should in no event
be regarded as an indication of any future market price of the Securities
offered hereby.

     Adjustments.  The exercise price and the number of shares of Common Stock
purchasable upon the exercise of the Warrants are subject to adjustment upon the
occurrence of certain events, including stock dividends, stock splits,
combinations or reclassifications of the Common Stock or the sale by the Company
of its Common Stock or other securities convertible into Common Stock at a price
below the exercise price of the Warrants. Additionally, an adjustment would be
made in the case of a reclassification or exchange of Common Stock,
consolidation or merger of the Company with or into another corporation (other
than a consolidation or merger in which the Company is the surviving
corporation) or sale of all or substantially all of the assets of the Company,
in order to enable warrantholders to acquire the kind and number of shares of
stock or other securities or property receivable in such

                                       40

<PAGE>

event by a holder of the number of shares of Common Stock that might otherwise
have been purchased upon the exercise of the Warrant.

     Redemption Provisions.  Commencing              , 1998 [eighteen (18)
months after the date of this Prospectus], the Warrants are subject to
redemption by the Company, in whole but not in part, at $.10 per Warrant on
thirty (30) days' prior written notice to the warrantholders, if the average
closing bid price of the Common Stock as reported on Nasdaq equals or exceeds
$         per share [200% of the initial public offering price per share of
Common Stock] for any twenty (20) trading days within a period of thirty (30)
consecutive trading days ending on the fifth trading day prior to the date of
the notice of redemption. In the event the Company exercises the right to redeem
the Warrants, such Warrants will be exercisable until the close of business on
the business day immediately preceding the date for redemption fixed in such
notice. If any Warrant called for redemption is not exercised by such time, it
will cease to be exercisable and the holder will be entitled only to the
redemption price.

     Transfer, Exchange and Exercise.  The Warrants are in registered form and
may be presented to the Warrant Agent for transfer, exchange or exercise at any
time on or prior to their expiration date five (5) years from the date of this
Prospectus, at which time the Warrants will become wholly void and of no value.
If a market for the Warrants develops, the holder may sell the Warrants instead
of exercising them. There can be no assurance, however, that a market for the
Warrants will develop or continue.

     Warrantholder Not a Stockholder.  The Warrants do not confer upon holders
thereof any voting, dividend, or other rights as stockholders of the Company.

     Modification of Warrants.  The Company and the Warrant Agent may make such
modifications to the Warrants as they deem necessary and desirable that do not
adversely affect the interests of the warrantholders. The Company may, in its
sole discretion, lower the exercise price of the Warrants for a period of not
less than thirty (30) days on not less than thirty (30) days' prior written
notice to the warrantholders and the Representative. Modification of the number
of securities purchasable upon the exercise of any Warrant, the exercise price
(other than as provided in the preceding sentence) and the expiration date with
respect to any Warrant requires the consent of two-thirds of the warrantholders.
 

     The Warrants are not exercisable unless, at the time of the exercise, the
Company has a current prospectus covering the shares of Common Stock issuable
upon exercise of the Warrants, and such shares have been registered, qualified
or deemed to be exempt under the securities or "blue sky" laws of the state of
residence of the exercising holder of the Warrants. Although the Company has
undertaken to use its best efforts to have all of the shares of Common Stock
issuable upon exercise of the Warrants registered or qualified on or before the
exercise date and to maintain a current prospectus relating thereto until the
expiration of the Warrants, there can be no assurance that it will be able to do
so.

     The Warrants are separately transferable immediately upon issuance.
Although the Securities will not be knowingly be sold to purchasers in
jurisdictions in which the Securities are not registered or otherwise qualified
for sale, investors in such jurisdictions may purchase Warrants in the secondary
market or investors may move to jurisdictions in which the shares underlying the
Warrants are not so registered or qualified during the period that the Warrants
are exercisable. In such event, the Company would be unable to issue shares to
those persons desiring to exercise their Warrants, and holders of Warrants would
have no choice but to attempt to sell the Warrants in a jurisdiction where such
sale is permissible or allow them to expire unexercised.

Limitations on Liability of Officers and Directors

     The Company's Certificate of Incorporation provides for indemnification of
the officers and directors of the Company to the fullest extent permitted by
Delaware law, including some instances in which indemnification is otherwise
discretionary under Delaware law. The Certificate of Incorporation contains
provisions that eliminate the personal liability of the Company's directors for
monetary damages resulting from breaches of their fiduciary duty (other than
liability for breaches of the director's duty of loyalty to the Company or its
stockholders), for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, violations under Section
174 of the Delaware General Corporation Law, or for any transaction from which
the director derived an improper personal benefit. The Company believes that
these provisions are essential to attracting and retaining qualified persons as
officers and directors.

                                       41

<PAGE>


     Presently there is no pending litigation or proceeding involving a director
or officer of the Company as to which indemnification is being sought, nor is
the Company aware of any threatened litigation that may result in claims for
indemnification by any officer or director.

Registration Rights

     The holders of the 175,000 shares of Common Stock issued in connection with
the sale of the Bridge Notes are entitled to certain rights with respect to the
registration of such shares under the Securities Act. In the event that the
Company proposes to register any of its securities under the Securities Act,
except in connection with this Offering or pursuant to a registration statement
on Forms S-4 or S-8, or similar or successor forms, such holders are entitled to
include such shares of Common Stock in such registration, subject to the right
of the underwriters of any such offering to limit the number of shares included
in such registration. The holders of at least 25% of such shares have the
additional right to require the Company to prepare and file a registration
statement under the Securities Act on Form S-3, or any successor form relating
to secondary offerings, at any time after the Company becomes eligible to file a
registration statement on Form S-3. The Company is not currently eligible to
file a registration statement on Form S-3 and will not be so eligible until it
has a security registered under Section 12 of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and has timely filed all reports and
proxy material required to be filed pursuant to Sections 13, 14 and 15(d) of the
Exchange Act for at least the 12 calendar months preceding the filing of such
registration statement on Form S-3. The Company is required to use its best
efforts to effect the registrations described above and is generally required to
bear the expenses of all such registrations.

Anti-takeover Provisions

     Section 203 of the Delaware General Corporation Law prevents an "interested
stockholder" (defined in Section 203, generally, as a person owning 15% or more
of a corporation's outstanding voting stock) from engaging in a "business
combination" (as defined in Section 203) with a publicly-held Delaware
corporation for three years following the date such person became an interested
stockholder unless (i) before such person became an interested stockholder, the
board of directors of the corporation approved the transaction in which the
interested stockholder became an interested stockholder or approved the business
combination; (ii) upon consummation of the transaction that resulted in the
interested stockholder's becoming an interested stockholder, the interested
stockholder owns at last 85% of the voting stock of the corporation outstanding
at the time the transaction commenced (excluding stock held by directors who are
also officers of the corporation and by employee stock plans that do not provide
employees with the right to determine confidentially whether shares held subject
to the plan will be tendered in a tender or exchange offer); or (iii) following
the transaction in which such person became an interested stockholder, the
business combination is approved by the board of directors of the corporation
and authorized at a meeting of stockholders by the affirmative vote of the
holders of 66 2/3% of the outstanding voting stock of the corporation not owned
by the interested stockholder.

Transfer Agent and Registrar

     The transfer agent and registrar for the Company's Common Stock and the
Warrant Agent for the Warrants is Continental Stock Transfer & Trust Company.

                        SHARES ELIGIBLE FOR FUTURE SALE


     Prior to the Offering, there has been no market for the Common Stock or the
Warrants of the Company, and no prediction can be made of the effect, if any,
that market sales of shares or the availability of shares for sale will have on
the market price prevailing from time to time. Nevertheless, sales of
substantial amounts of the Common Stock and the Warrants of the Company in the
public market could adversely affect prevailing market prices for the Common
Stock and the Warrants and the ability of the Company to raise equity capital in
the future.

     Upon completion of this Offering, the Company will have outstanding
3,800,655 shares of Common Stock and 1,800,000 Warrants. Of these securities,
the 1,800,000 Shares and 1,800,000 Warrants sold in this Offering will be
available for immediate sale in the public market without restriction under the
Securities Act, unless purchased by "affiliates" of the Company as that term is
defined in Rule 144 under the Securities Act.

     The remaining 2,000,655 shares held by existing stockholders will be
restricted securities as that term is defined in Rule 144 under the Securities
Act ("Restricted Shares"). Restricted Shares may be sold in the public market
only if registered under the Securities Act or if they qualify for an exemption
from registration under Rules 144 or 701 promulgated under the Securities Act.
Sales of the Restricted Shares in the public market, or the availability of such
shares for sale, could adversely affect the market prices of the Common Stock
and Warrants.

     All officers and directors of the Company have agreed not to, directly or
indirectly, offer, agree or offer to sell, sell, transfer, pledge, assign,
encumber, grant an option for the purchase or sale of, hypothecate or otherwise
dispose of any beneficial interest in such securities for a period of 24 months
following the effective date of the Registration Statement without the prior
written consent of the Company and the Representative.

     As a result of these contractual restrictions, shares subject to lock-up
agreements will not be saleable until the agreements expire. Upon expiration of
the lock-up period, no shares of Common Stock will be eligible for sale pursuant
to Rule 701 and 2,000,655 shares will be eligible for sale under Rule 144.

     In general, under Rule 144 a person (or persons whose shares are
aggregated) who has beneficially owned Restricted Shares for at least one year
(including the holding period of any prior owner except an affiliate) would be
entitled to sell within any three-month period a number of shares that does not
exceed the greater of (i) one percent of the number of shares of Common Stock
then outstanding (approximately 38,000 shares immediately after this Offering),
or (ii) the average weekly trading volume of the Common Stock during the four
calendar weeks preceding the filing of a Form 144 with respect to such sale.
Sales under Rule 144 are also subject to certain manner of sale provisions and
notice requirements and to the availability of current public information about
the Company. Under Rule 144(k), a person who is not deemed to have been an
affiliate of the Company at any time during the 90 days preceding a sale, and
who has beneficially owned the shares proposed to be sold for at least two years
(including the holding period of any prior owner except an affiliate), is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144.

                                 UNDERWRITING

     The Underwriters named below (the "Underwriters"), for whom National
Securities Corporation is acting as representative (in such capacity, the
"Representative"), have severally agreed, subject to the terms and conditions of
the Underwriting Agreement (the "Underwriting Agreement") to purchase from the
Company and the Company has agreed to sell to the Underwriters on a firm
commitment basis, the respective number of Shares and Warrants set forth
opposite their names:

<TABLE>
<CAPTION>
             Underwriter                    Number of Shares      Number of Warrants
             -----------                    ----------------      ------------------
<S>                                         <C>                   <C>
National Securities Corporation   ......

  Total   ..............................    1,800,000             1,800,000

</TABLE>


     The Underwriters are committed to purchase all the Shares of Common Stock
and Warrants offered hereby, if any of such securities are purchased. The
Underwriting Agreement provides that the obligations of the several Underwriters
are subject to conditions precedent specified therein.

     The Company has been advised by the Representative that the Underwriters
propose initially to offer the Securities to the public at the initial public
offering prices set forth on the cover page of this Prospectus and to certain
dealers at such prices less concessions not in excess of $      per Share and
$   per Warrant. Such dealers may reallow a concession not in excess of $
per Share and $       per Warrant to certain other dealers. After the
commencement of the Offering, the public offering prices, concession and
reallowance may be changed by the Representative.

     The Representative has informed the Company that it does not expect sales
to discretionary accounts by the Underwriters to exceed five percent of the
Securities offered hereby.

     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that the Underwriters may be required to make. The Company has also
agreed to pay to the Representative a non-accountable expense allowance equal to
3% of the gross proceeds derived from the sale of the Securities underwritten,
of which $50,000 has been paid to date.

     The Company has granted to the Underwriters an over-allotment option,
exercisable during the forty-five (45) day period from the date of this
Prospectus, to purchase up to an additional 270,000 shares of Common Stock
and/or 270,000 Warrants at the initial public offering price per Share and
Warrant, respectively, offered hereby, less underwriting discounts and the
non-accountable expense allowance. Such option may be exercised only for the
purpose of covering over-allotments, if any, incurred in the sale of the
Securities offered hereby. To the extent such option is exercised in whole or in
part, each Underwriter will have a firm commitment, subject to certain
conditions, to purchase the number of the additional Securities proportionate to
its initial commitment.

     In connection with this Offering, the Company has agreed to sell to the
Representative, for nominal consideration, warrants to purchase from the Company
up to 180,000 shares of Common Stock and/or 180,000 Warrants (the
"Representative's Warrants"). The Representative's Warrants are initially
exercisable at a price of $     per share of Common Stock [120% of the initial
public offering price per share of Common Stock] and $      per Warrant [120% of
the initial public offering price per Warrant] for a period of four (4) years,
commencing at the beginning of the second year after their issuance and sale and
are restricted from sale, transfer, assignment or hypothecation for a period of
twelve (12) months from the date hereof, except to officers of the
Representative. The Representative's Warrants provide for adjustment in the
number of shares of Common Stock and Warrants issuable upon the exercise thereof
and in the exercise price of the Representative's Warrants as a result of
certain events, including subdivisions and combinations of the Common Stock. The
Representative's Warrants grant to the holders thereof certain rights of
registration for the securities issuable upon exercise thereof.

     The Underwriting Agreement further provides that the Representative may
designate for election one person to the Company's Board of Directors for a
period of one (1) year from the effective date of the Registration Statement. In
the event the Representative elects not to exercise this right, the
Representative may designate one person to attend meetings of the company's
Board of Directors. Such designee will be entitled to attend all meetings of the
Company's Board of Directors and to receive all notices and other correspondence
and communications sent by the Company to members of its Board of Directors. The
Company will reimburse the designee of the

                                       44

<PAGE>

Representative for his out-of-pocket expenses incurred in connection with
attendance at meetings of the Company's Board of Directors.

     All officers and directors and stockholders of the Company have agreed not
to, directly or indirectly, offer, agree or offer to sell, sell, transfer,
pledge, assign, encumber, grant an option for the purchase or sale of,
hypothecate or otherwise dispose of any beneficial interest in such securities
for a period of 24 months following the effective date of the Registration
Statement without the prior written consent of the Company and the
Representative. An appropriate legend will be marked on the face of certificates
representing all such securities.

     In connection with this Offering, certain Underwriters and selling group
members and their respective affiliates may engage in transactions that
stabilize, maintain or otherwise affect the market prices of the Securities.
Such transactions may include stabilization transactions effected in accordance
with Rule 104 of Regulation M, pursuant to which such persons may bid for or
purchase the Common Stock and/or Warrants for the purpose of stabilizing their
respective market prices. The Underwriters also may create a short position for
the account of the Underwriters by selling more Securities in connection with
the Offering than they are committed to purchase from the Company, and in such
case may purchase Securities in the open market following completion of the
Offering to cover all or a portion of such short position. The Underwriters may
also cover all or a portion of such short position, up to 270,000 shares of
Common Stock and/or 270,000 Warrants, by exercising the over-allotment option
referred to above. In addition, the Representative may impose "penalty bids"
under contractual arrangements with the Underwriters whereby it may reclaim from
an Underwriter (or dealer participating in the Offering) for the account of
other Underwriters, the selling concession with respect to the Securities that
are distributed in the Offering but subsequently purchased for the account of
the Underwriters in the open market. Any of the transactions described in this
paragraph may result in the maintenance of the prices of the Securities at a
level above which might otherwise prevail in the open market. None of the
transactions described in this paragraph is required, and, if they are
undertaken, they may be discontinued at any time.

     Prior to this Offering, there has been no public market for the Common
Stock or the Warrants. Consequently, the initial public offering prices of the
Securities have been determined by negotiation between the Company and the
Representative and do not necessarily bear any relationship to the Company's
asset value, net worth, or other established criteria of value. The factors
considered in such negotiations, in addition to prevailing market conditions,
included the history of and prospects for the industry in which the Company
competes, an assessment of the Company's management, the prospects of the
Company, its capital structure, the market for initial public offerings and
certain other factors as were deemed relevant.

     Upon the exercise of any Warrants more than one year after the date of this
Prospectus, which exercise was solicited by the Representative, and to the
extent not inconsistent with the guidelines of the National Association of
Securities Dealers, Inc. and the Rules and Regulations of the Commission, the
Company has agreed to pay the Representative a commission of 5% of the aggregate
exercise price of such Warrants. However, no compensation will be paid to the
Representative in connection with the exercise of the Warrants if (a) the market
price of the Common Stock is lower than the exercise price, (b) the Warrants are
held in a discretionary account, or (c) the Warrants are exercised in an
unsolicited transaction where the holder of the Warrant has not stated in
writing that the transaction was solicited and has not designated in writing the
Representative as soliciting agent. Unless granted an exemption by the
Commission from its Rule 101 under Regulation M promulgated under the Securities
Act, the Representative and any soliciting broker-dealers will be prohibited
from engaging in any market-making activities or solicited brokerage activities
with regard to the Company's securities for the period from five business days
(or such applicable periods as Rule 101 under Regulation M may provide) prior to
any solicitation of the exercise of the Warrants until the later of the
termination of such solicitation activity or the termination (by waiver or
otherwise) of any right the Representative may have to receive a fee for the
exercise of the Warrants following such solicitation. As a result, the
Representative and any soliciting broker-dealers may be unable to continue to
provide a market for the Common Stock or Warrants during certain periods while
the Warrants are exercisable. If the Representative has engaged in any of the
activities prohibited by Rule 101 under Regulation M during the periods
described above, the Representative has undertaken to waive unconditionally its
rights to receive a commission on the exercise of such Warrants.

     The foregoing is a summary of the principal terms of the agreements
described above and does not purport to be complete. Reference is made to a copy
of each such agreement which are filed as exhibits to the Registration Statement
of which this Prospectus is a part for a more complete description thereof. See
"Additional Information."

                    UNAUDITED PRO FORMA FINANCIAL STATEMENTS
                                        
                             BASIS OF PRESENTATION

     The following unaudited pro forma financial statements (i) give effect to
the Acquisitions pursuant to which the Company will acquire substantially all of
the equity interests of the Initial MSOs that hold certain assets of and are
associated with the seven Initial Orthodontic Affiliates (except in the case of
one sole proprietorship where it will acquire certain assets of such
proprietorship) in exchange for 315,655 shares of the Company's Common Stock,
cash, notes payable, stock options and the assumption of certain liabilities and
(ii) reflect the effects of the provisions of the Affiliation Agreements and
Management Services Agreements between the Company and each of the Initial
Orthodontic Affiliates. For purposes of developing the unaudited pro forma
balance sheet, the value of the Company's Common Stock is based upon the assumed
initial public offering price of $6.00 per share. The estimated aggregate
amounts to be allocated to the net assets acquired consist of:

 Common stock                                 $1,893,930
 Cash                                          2,098,464
 Notes payable                                   794,434
                                              -----------
                                              $4,786,828

     The allocation is based upon preliminary estimates in accordance with
generally accepted accounting principles. The actual allocation will be based on
the estimated fair market value of the tangible and intangible assets and
liabilities of such Initial MSOs (and the proprietorship) as of the date of the
Acquisitions. For purposes of the pro forma financial statements, such
allocation has been estimated as follows:

 Current assets                             $    795,033
 Intangible assets                             4,804,199
 Property, equipment and improvements            342,723
 Liabilities                                  (1,155,127)
                                             ------------
                                            $  4,786,828
                                             ============


     The unaudited pro forma financial statements have been prepared by the
Company based upon the historical financial statements of Omega and the Initial
Orthodontic Affiliates included elsewhere in this Prospectus and certain
preliminary estimates and assumptions deemed appropriate by management of the
Company. The pro forma balance sheet as of December 31, 1996 gives effect to the
Acquisitions as if such transactions had occurred on December 31, 1996 and
reflects certain transactions occurring subsequent to December 31, 1996
including (i) the issuance of $300,000, of additional notes payable and related
60,000 shares of Common Stock for no additional consideration, (ii) the issuance
of 10,000 shares of Common Stock under a previous agreement with the Chief
Financial Officer and (iii) the release from escrow of 450,000 shares of Common
Stock previously issued to the Chairman of the Board of Directors and a private
bank upon completion of certain financial advisory services and the additional
obligation of approximately $842,000 for such services to be paid over three
years beginning January 1, 1998. The pro forma statement of operations for the
year ended December 31, 1996 assumes the Acquisitions were completed on January
1, 1996. These pro forma financial statements may not be indicative of actual
results as if the transactions had occurred on the dates indicated or which may
be realized in the future. Neither expected benefits nor cost efficiencies
anticipated by the Company following consummation of the Acquisitions have been
reflected in such pro forma financial statements; however, cost reductions as
contractually agreed per the Management Services Agreements have been reflected
in the pro forma financial statements. Moreover, the pro forma financial
statements do not include the non-recurring compensation expense of $2.2 million
that the Company will recognize during the quarter ending June 30, 1997. Also
the pro forma financial statements do not include any costs for travel,
consulting or professional fees associated with the identification, evaluation
and integration of additional Orthodontic Affiliates, which costs include
substantially all of the compensation of two executives of the Company. These
costs may be substantial and may cause the Company to incur operating losses.
Moreover, pro forma management expenses do not include the anticipated
incremental costs of managing such additional Orthodontic Affiliates as the
related management fees are not included in the pro forma revenues. Such costs
may also be substantial and may vary according to the operations of each new
Orthodontic Affiliate.

     The pro forma financial statements should be read in conjunction with the
historical financial statements of Omega and each of the Initial Orthodontic
Affiliates, including the related notes thereto, and "Management's Plan of
Operation" that appear elsewhere in this Prospectus.

                          Notes to Unaudited Pro Forma
                              Financial Statements


     The accompanying unaudited pro forma financial statements present the pro
forma financial position of the Company as of December 31, 1996 and the pro
forma results of its operations for the year ended December 31, 1996. The
Company was incorporated in August 1996.

     The unaudited pro forma financial statements also include the historical
financial position at December 31, 1996 and results of operations for the year
ended December 31, 1996 of all of the following entities which comprise the
Initial Orthodontic Affiliates:

   Michael G. Churosh, D.D.S., M.S., Ltd.
   Dr. Scott E. Feldman, D.D.S., M.S.
   Theodore G. Saydyk, Jr., D.D.S., M.S., P.C.

   Clark E. Schneekluth, D.D.S., M.D., Inc.
   Jeff S. Zapalac, D.D.S., M.S., Inc.
   David T. Grove, D.M.D.

Unaudited Pro Forma Balance Sheet Adjustments:

1. Historical assets and liabilities of the Initial Orthodontic Affiliates are
    included in the pro forma balance sheet pursuant to the terms and conditions
    of the underlying Affiliation Agreements. The pro forma balance sheet
    reflects excluded assets and liabilities that are not to be acquired or
    assumed as part of the Affiliation Agreements, including all cash and cash
    equivalents, notes receivable and payable to the Initial Orthodontic
    Affiliates and any amounts owed by the Initial Orthodontic Affiliates which
    are unrelated to the assets acquired.

2. Represents the adjustment of gross patient receivables and deferred revenue
    (patient prepayments) to reflect the portion of practice revenue retained by
    the Affiliated Orthodontists.

3. Represents the allocation of the purchase price to the assets and liabilities
    at their estimated fair market values at the date of consummation of the
    Acquisitions. Upon consummation of this Offering, the Company will pay the
    $2,098,464 included in the unaudited pro forma balance sheet as due to
    Orthodontic Affiliates and issue Common Stock and stock options as outlined
    in the Affiliation Agreements.

4. Represents the elimination of historical owners' equity (deficit) of the
    Initial Orthodontic Affiliates.

                                                                                
5. To reflect certain transactions occurring subsequent to December 31, 1996
    including (a) the issuance of 10,000 shares of Common Stock for past
    services to the Chief Financial Officer, (b) the issuance of Bridge Notes
    in the aggregate principal amount of $300,000, and 60,000 shares of Common
    Stock issued in connection therewith, (c) a non-recurring consulting
    expense of approximately $2,200,000 comprised of approximately $1,400,000
    attributable to the release from escrow of 450,000 shares of Common Stock
    and the obligation for approximately $842,000 of cash payments beginning in
    January 1998.


Unaudited Pro Forma Statement of Operations Adjustments:

1. To adjust the Affiliated Orthodontists' compensation to agree with the
    Management Services Agreements. The Initial Orthodontic Affiliates retain
    the difference between practice revenue and the management fee earned by the
    Company. The Initial Orthodontic Affiliates typically earn 25% to 35% of
    practice revenue. In addition, a portion of the profits, if any, exceeding
    an agreed upon profit target will generally be shared with the Orthodontic
    Affiliate.

2. To adjust direct practice expenses of the Initial Orthodontic Affiliates to
    reflect the expenses that would have been payable under the Management
    Services Agreements. Excluded expenses represent those costs that the
    Initial Orthodontic Affiliates are responsible for paying directly,
    including salaries and benefits of the Affiliated

                        Financial Statements (Continued)

 

   Orthodontist and any other practice providers, physician licensing fees,
    board certification fees, professional liability insurance premiums,
    certain professional education expenses and legal and professional fees.

3. To adjust bad debt expense to reflect only the portion related to the
    Company's net management revenue and related patient receivables.

4. To adjust depreciation and amortization expense to reflect the exclusion of
    certain fixed assets from the historical assets purchased in accordance with
    the Affiliation Agreements.

5. To increase management expenses to reflect an estimate of a full year of
    operations and management of only the seven Initial Orthodontic Affiliates
    but does not include the non-recurring compensation expense of $2,200,000
    that the Company will recognize in April 1997 for payments made to two 
    consultants for past services rendered. Moreover, costs that will be 
    incurred related to identifying, evaluating and integrating additional 
    Orthodontic Affiliates have not been included. Such costs could be 
    substantial and may cause the Company to incur operating losses.

6. Represents the amortization of intangible assets over 40 years.

7. Represents elimination of interest expense associated with the liabilities
    excluded from the historical liabilities assumed in accordance with the
    Affiliation Agreements. Also represents the elimination of interest income
    earned on cash excluded from the historical assets purchased in accordance
    with the Affiliation Agreements.

8. Represents the elimination of interest expense incurred in connection with
    the Bridge Notes (loans payable) that is assumed to be paid off from the
    proceeds of this Offering.

9. To adjust interest expense to reflect the amount incurred in connection with
    the issuance of debt in connection with the Acquisitions.

10. To increase other consulting fees to reflect a full year of consulting fees
    earned from non-affiliated orthodontic practices. The historical statement
    of operations of Omega represents operating results from August 30, 1996.

11. To reflect federal and state income taxes assuming a 40% statutory income
    tax rate, increased by the non-deductible portion of goodwill amortization.

12. Based upon the historical shares used to compute net income per share
    increased by (i) the issuance of 60,000 shares of Common Stock in
    connection with additional Bridge Notes issued subsequent to December 31,
    1996, (ii) the assumed issuance of 145,833 shares of Common Stock to repay
    $875,000 of outstanding Bridge Notes and (iii) the issuance of 315,655
    shares of Common Stock at the assumed initial public offering price of
    $6.00 per share in connection with the assumed affiliation with the seven
    Initial Orthodontic Affiliates.

                         Report of Independent Auditors


To the Board of Directors and Stockholders
Omega Orthodontics, Inc.


We have audited the accompanying balance sheet of Omega Orthodontics, Inc. (the
Company) as of December 31, 1996 and the related statements of operations,
stockholders' deficit, and cash flows for the period from August 30, 1996 
(inception) to December 31, 1996. These financial statements are the 
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Omega Orthodontics, Inc. as of
December 31, 1996, and the results of its operations and its cash flows for the
initial period then ended in conformity with generally accepted accounting
principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1, the Company
has an accumulated deficit of $232,112, and a working capital deficiency of
$368,032 at December 31, 1996. These conditions raise substantial doubt about
the Company's ability to continue as a going concern. Management's plans in
regard to these matters are also described in Note 1. The financial statements
do not include any adjustments to reflect the possible future effects on the
recoverability and classification of assets or the amounts and classification of
liabilities that may result from the outcome of this uncertainty.

                          Notes to Financial Statements

                                December 31, 1996



1. Summary of Significant Accounting Policies

The Company

Omega Orthodontics, Inc., (the Company) was incorporated in Delaware in August
1996 and subsequently acquired the assets and certain consulting contracts held
by The Orthodontic Management Effectiveness Group of America, LLC (Omega, LLC),
a California-based orthodontic practice management and consulting firm, in
exchange for 1,050,000 shares of the Company's common stock.

The Company will provide management and marketing services to orthodontic
practices in the United States. The Company offers its services primarily under
an "affiliate" relationship whereby it purchases the equity interests of the
management services organization that holds certain assets of and is associated
with an orthodontic practice and enters into a long term management services
agreement with the practice of the selling orthodontist. Pursuant to that
agreement, the Company receives a monthly management fee for providing all of
the orthodontist's practice needs, including facility, staff and supplies, as
well as a program of systems, methods and procedures designed to enhance the
growth, efficiency and profitability of the practice.

Going Concern

The Company has no significant operating history and has an accumulated deficit
of $232,112, and a working capital deficiency of $368,032 at December 31, 1996.
In order to continue operations, the Company is seeking to raise capital through
the initial public offering as contemplated in this Prospectus. If such offering
is not successful, the Company would need to scale back operations, seek
alternative financing sources which are not now available, or both.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statement and the
reported amount of revenues and expenses during the reported period. Actual
results could differ from those estimates.

                    Notes to Financial Statements (Continued)

1.  Summary of Significant Accounting Policies (continued)

Cash and Cash Equivalents

For purposes of its cash flow statement, the Company considers all highly liquid
investments with original maturities of three month or less when purchased to be
cash and cash equivalents.

Equipment

Equipment is stated at cost. Depreciation expense is provided using the
straight-line method over the estimated useful lives of the assets, which is
five years. Equipment cost amounted to $11,212 and accumulated depreciation
amounted to $1,116 at December 31, 1996.

Intangible assets

Intangible assets, consisting primarily of goodwill and organizational costs,
are amortized on a straight line basis over useful lives of five to forty years.

Revenue Recognition

The Company provides management consulting services to orthodontic practices
under consulting agreements. Revenue is recognized as the services are provided.

Income Taxes

The Company provides for income taxes under the liability method prescribed by
Statement of Financial Accounting, Standards (SFAS) No. 109, "Accounting for
Income Taxes." Under this method, deferred tax liabilities and assets are
determined based on the difference between the financial statement and tax basis
of assets and liabilities using enacted tax rates in effect for the year in
which the differences are expected to reverse. SFAS No. 109 requires that the
Company record a valuation allowance when it is more likely than not that some
portion or all of the deferred tax assets will not be realized. Due to the
uncertainty of the Company's ability to realize the benefit of the deferred tax
assets, a full valuation allowance has been applied against the deferred tax
assets at December 31, 1996. The Company prepares its tax return on the cash
basis.

                    Notes to Financial Statements (Continued)


1.  Summary of Significant Accounting Policies (continued)

Net Loss Per Share

Net loss per share is computed using the weighted average number of outstanding
shares of common stock and common stock equivalents, and the exercise of stock
options (using the treasury stock method). Common stock equivalent shares are
excluded from the computation if their effect is anti-dilutive; however,
pursuant to the requirements of the Securities and Exchange Commission, common
shares and common equivalent shares relating to stock options (using the
treasury stock method and the initial public offering price) issued during the
twelve months prior to the filing of an initial public offering are considered
outstanding for all periods presented whether or not they are anti-dilutive.

2. Other Assets

Other assets are comprised of the following at December 31, 1996:

Deferred offering costs                                   $101,228
Debt financing costs                                        38,844
Intangible assets                                            8,216
                                                      ---------------
                                                           148,288
Less accumulated amortization                               10,814
                                                      ---------------

Other assets, net                                         $137,474
                                                      ===============

Deferred offering costs include all expenses incurred in connection with the
preparation of the initial public offering as contemplated in this Prospectus,
but does not include any costs contingent upon consummation of the offering (see
Note 4). Debt financing costs incurred in connection with the issuance of
$575,000 of notes payable are being amortized over the term of the debt (see
Note 3).

3.  Notes Payable

During 1996, the Company issued a series of notes in the aggregate principal
amount of $575,000. The notes bear interest at 15% per annum and are due on the
earlier of September 30, 1997 or upon consummation of an initial public offering
as contemplated in this Prospectus. In consideration for the purchase of the
notes, the Company issued to the noteholders 115,000 shares of common stock for
no additional payment (see Note 8).

                    Notes to Financial Statements (Continued)


4.  Stockholders' Deficit

The Board of Directors voted to amend the Certificate of Incorporation and
revise the number of authorized shares of common stock to 9,500,000 and
authorize 500,000 shares of preferred stock, $.01 par value, effective February
12, 1997. The preferred stock shares will be issuable in one or more series,
each such series to have such rights and preferences, including voting rights,
dividend rights, conversion rights, redemption privileges and liquidation
preferences, as shall be determined by the Board of Directors.

The Company adopted a Stock Incentive Plan (the Plan) effective January 31,
1997. Plan awards in the form of stock options, stock appreciation rights,
restricted stock, and stock grants may be issued to employees, consultants and
advisers of the Company at prices to be determined by the Board of Directors.
The Plan will terminate on January 30, 2007. A total of 300,000 shares of common
stock were initially reserved for issuance under the Plan and no grants were
made as of December 31, 1996 (see Note 8 for subsequent revisions).

The Company has an agreement with a private bank and the Chairman of the Board
of Directors (the Advisers), whereby the Advisers have agreed to provide certain
consulting and financial advisory services to the Company. As consideration for
such services, the Company contingently issued 450,000 shares of common stock to
the Advisers at no additional cost and simultaneously placed such shares in
escrow. As of December 31, 1996, the 450,000 shares are included in outstanding
common stock at their nominal fair value at the date of issuance with a
corresponding deferred charge. These shares were subsequently released from
escrow upon completion of such services (see Note 8).

The Company has agreed to issue 10,000 shares of common stock for nominal
consideration to the chief financial officer of the Company in return for
assistance in the preparation of financial information and performance of the
related duties. These shares were subsequently issued upon completion of
services (see Note 8).

                    Notes to Financial Statements (Continued)


5.  Income Taxes

Since the Company has incurred only losses since inception, and due to the
degree of uncertainty related to the use of the loss carryforwards, the Company
has fully reserved this benefit. At December 31, 1996, the Company had tax net
operating loss carryforwards of approximately $232,112 available to offset
federal and state taxable income which expire in 2011. In accordance with
Section 382 of the Internal Revenue Code, the use of the above carryforwards may
be subject to annual limitations based upon ownership changes of the Company's
stock which have occurred.

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax assets as of December 31, 1996 are as follows:

Net operating loss carryforwards                              $ 92,845
Valuation allowance                                            (92,845)
                                                          --------------

Net deferred tax asset                                        $      0
                                                          ==============


6.  Related Party Transactions

Two Directors of the Company purchased an aggregate of $75,000 of the notes
payable and received 15,000 shares of the Company's common stock in connection
therewith. (See Note 8 for subsequent issuances). In addition, three Directors
performed consulting services for the Company for which they were compensated an
aggregate of approximately $90,000 in 1996.

7.  Commitments and Contingencies

Since its inception in August 1996, the Company has undertaken to enter into
certain affiliate agreements with seven orthodontic practices (affiliate
orthodontists) in the United States. In the event of a successful public
offering of the Company's common stock, these agreements provide for the
purchase by the Company of the equity interests in a management services
organization (MSO) to be formed by the selling orthodontist for consideration
ranging from $342,000 to $1,082,000 for each such MSO. The estimated aggregate
purchase price of the seven practices under agreement, $4,787,000, will be paid
through a combination of cash of approximately $2,098,000, five-year term notes
totaling $794,000 and shares of common stock of the Company with a fair value at
the date of issue of approximately $1,894,000.

Concurrent with the acquisition of the MSO, the Company and the MSO enter into a
20-year management services agreement, renewable for an additional 20 years,
with each affiliate orthodontist. The agreement will stipulate that the MSO
provide practice management and marketing services, facilities and non-clinical
personnel to the affiliate orthodontic for a monthly fee, generally equal to 65%
to 75% of the affiliate orthodontist's gross patient fee collections.
Conversely, the affiliate orthodontist will have sole authority to direct the
business, professional and ethical aspects of the practice, make all
professional hiring decisions, render patient care, and keep all patient dental
records. The affiliate orthodontist will also be responsible for entering into
an employment agreement, including non-competition provisions, with each
orthodontist employed and paying all salaries for dental professionals,
professional licensure and board certification fees and professional liability
insurance premiums.

The affiliate orthodontist will have certain rights and obligations to
repurchase, and the MSO will have the right to require the affiliate
orthodontist to repurchase, the non-clinical practice assets held by the MSO in
the event that the management services agreement is terminated. Such purchases
will generally require payment of the book value of the net assets of the MSO.
The MSO will also have certain rights to designate a successor orthodontist to
acquire the practice of the affiliate orthodontist when the orthodontist ceases
practice.

The acquisitions are anticipated to result in substantial goodwill which will be
amortized over the term of the management services agreement. All acquisitions
and related management services agreements are contingent upon the consummation
of the initial public offering as contemplated in this Prospectus.

8.  Subsequent Events

On April 28, 1997 and May 12, 1997, the Board of Directors took the following
actions: (i) voted to increase the number of shares of common stock authorized
for issuance under the Stock Incentive Plan (the Plan) to 450,000 shares (see
Note 4), which increase was approved by the stockholders, (ii) authorized the
issuance of additional notes payable in the aggregate principal amount of
$300,000, (iii) authorized the Company to enter into various employment and
consulting agreements, which included the granting of stock options under the
Company's Plan for an aggregate of 350,000 shares of common stock, vesting
ratably over periods of one to three years, at an exercise price equal to the
initial public offering price of the Company's common stock and, (iv) authorized
the release from escrow of 450,000 shares of common stock previously issued to
the Chairman of the Board of Directors and a private bank upon completion of
certain financial advisory services (see Note 4) and agreed to additional
consideration of approximately $842,000 for such services to be paid over three
years beginning January 1, 1998.


In consideration for the purchase of the notes, the Company issued to the
noteholders 60,000 shares of common stock for no additional payment (see Note
3). Included in the $300,000 notes payable and 60,000 shares of common stock
were $30,000 and 6,000 shares, respectively, issued to directors of the Company
(see Note 6). The issuance of the 450,000 shares and related consideration of
$842,000 will result in a charge to operating results of the Company of
approximately $2,200,000 in the second quarter of 1997.

                          Audited Financial Statements

                         Report of Independent Auditors



To the Board of Directors
Omega Orthodontics, Inc.


We have audited the accompanying balance sheets of Michael G. Churosh, D.D.S.,
M.S., Ltd. (the Company) as of December 31, 1996 and 1995, and the related
statements of income and accumulated deficit, and cash flows for the years then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Michael G. Churosh, D.D.S.,
M.S., Ltd. as of December 31, 1996 and 1995, and the results of its operations
and its cash flows for the years then ended in conformity with generally
accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1, the Company
has a stockholder's deficit of $174,512, and a working capital deficit of
$264,982 at December 31, 1996. These conditions raise substantial doubt about
the Company's ability to continue as a going concern. Management's plans in
regard to these matters are also described in Note 1. The financial statements
do not include any adjustments to reflect the possible future effects on the
recoverability and classification of assets or the amounts and classification of
liabilities that may result from the outcome of this uncertainty.

1.   Summary of Significant Accounting Policies

Nature of Business

The dental practice of Michael G. Churosh, D.D.S., M.S., Ltd. (the Company) is a
professional corporation which was incorporated August 31, 1970 in Phoenix,
Arizona for the primary purpose of practicing dentistry. The Company currently
maintains offices in Goodyear and Bullhead City, Arizona.

Basis of Presentation

The Company's financial statements have been presented on a going concern basis
which contemplates the realization of assets and the satisfaction of liabilities
in the normal course of business. At December 31, 1996, the Company has a
stockholder's deficit of $174,512 and a working capital deficit of $264,982.
Included in total assets is amounts due from stockholder of $109,746 at December
31, 1996.

These conditions indicate that the Company's ability to continue as a going
concern will be dependent upon its ability to generate sufficient cash flow to
meet its liabilities as they become due, including obtaining financing from
outside sources. Management expects to obtain adequate capital from its
contemplated transaction with Omega Orthodontics, Inc. (Omega) (see Note 9).
Should the transaction with Omega not be consummated, management will seek
financing through other sources, however, there can be no assurance that such
sources of capital will be available, on terms and conditions acceptable to the
Company, and that the pending transaction with Omega will be completed. The
financial statements do not include any adjustments to reflect the possibility
of future effects on the classification and recoverability of assets or the
liabilities that might result if the Company were not able to continue as a
going concern in its present form.

Equipment and Improvements

Equipment and improvements are stated at cost. Depreciation expense is provided
using the straight-line method over the estimated useful lives of the assets,
which range from five to seven years. Amortization of leasehold improvements is
provided over the term of the lease or their estimated useful life, whichever is
shorter.

Orthodontic Supplies and Materials

Orthodontic supplies and materials are expensed as incurred.

1.   Summary of Significant Accounting Policies (continued)

Revenue Recognition

Revenue is recognized in accordance with the proportional performance method of
accounting for service contracts. Under this method, revenue is recognized as
services are performed and the costs associated therewith are incurred, under
the terms of contractual agreements with each patient. A significant portion,
approximately 25%, of the services are performed in the initial month of the
contract. Billings under each contract, which vary in duration from 12 to 24
months, are made throughout the term of the contract. Provisions are made
currently for all known or anticipated losses from patient receivables and for
loss contracts. Such deductions totaled $24,000 and $22,000 in 1996 and 1995,
respectively. Patient prepayments represent collections from patients or their
insurance companies which are received in advance of the performance of the
related services.

Risks and Uncertainties

Concentration of Credit Risk
- ----------------------------

Financial instruments which subject the Company to credit risk consist
primarily of patient receivables. The risk with respect to patient receivables
is minimized due to the fact that patients remit a substantial portion of their
contract fee in advance. The Company generally does not require collateral, and
credit losses consistently have been within management's expectations.

Use of Estimates
- ----------------

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statement and the
reported amount of revenues and expenses during the reported period. Actual
results could differ from those estimates.

Impairment of Long-Lived Assets

In 1996, the Company adopted Statement of Financial Accounting Standards (SFAS)
No. 121 "Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed
of". SFAS No. 121 requires recognition of impairment losses on long-lived assets
when indicators of impairment losses on long-lived assets are present and future
undiscounted cash flows are insufficient to support the assets' recovery.
Adoption of SFAS No. 121 had no material impact on the Company's financial
statements.

1.   Summary of Significant Accounting Policies (continued)

Income Taxes

The Company provides for income taxes under the liability method prescribed by
Statement of Financial Accounting, Standards (SFAS) No. 109, "Accounting for
Income Taxes". Under this method, deferred tax liabilities and assets are
determined based on the difference between the financial statement and tax basis
of assets and liabilities using enacted tax rates in effect for the year in
which the differences are expected to reverse. SFAS No. 109 requires that the
Company record a valuation allowance when it is more likely than not that some
portion or all of the deferred tax assets will not be realized. Due to the
uncertainty of the Company's ability to realize the benefit of the deferred tax
assets, a full valuation allowance has been applied against the net deferred tax
assets in 1996 and 1995. The Company prepares its tax returns on the cash basis.

Intangible Assets

Intangible assets consist of goodwill and a five-year covenant not to compete
associated with the purchase of the Bullhead City office. These costs are being
amortized on a straight-line basis over a five-year period.

Professional Liability Insurance

The Company has obtained professional liability coverage through commercial
insurance carriers on a claims-made basis. Management believes that there are no
claims that may result in a loss in excess of amounts covered by its existing
insurance.

5.   Related-Party Transactions

The note receivable from the sole stockholder accrues interest at 8% per annum
and is due on demand. The sole stockholder received approximately $146,000 and
$110,000 of compensation from the Company in 1996 and 1995, respectively, which
is included in employee costs. In addition, the stockholder is the principal
owner of the building in which the Company leases its Goodyear office space. No
rent was charged to the Company for the Goodyear facility prior to April 1996.

6.  Leases

The Company's Bullhead City office space is rented under an operating lease
which expires in April 1998. The Goodyear office space is rented under a tenant
at will agreement ($2,500 per month). In addition, the Company leases certain
equipment under lease agreements which have been accounted for as operating
leases. The lease agreements expire at various times through 1998. The future
minimum annual rental commitments under these long-term noncancellable leases
are as follow:

7.  Profit-Sharing Plan

Employees of the Company who have completed twelve months of service and who
have reached the age of 21 are eligible to participate in the Company's

contributions. The only source of contributions to the Plan is the annual
employer contributions which are made at the discretion of the board of
directors, and may not exceed 25% of an employee's annual compensation. There
were no employer contributions in 1996 or 1995.

9.   Contingent Practice Acquisition

The Company has entered into an agreement with Omega, a company recently
organized to provide management and marketing services to orthodontic practices
in the United States. In the event of a successful public offering of Omega's
common stock, this agreement provides for the purchase by Omega of the equity
interests in a management services organization (MSO) to be formed by the
Company's sole stockholder converting the Company into a general corporation
which will hold certain assets of the Company. The agreement provides for the
payment by Omega of $1,082,058, consisting of cash of $530,208 and shares of
common stock of Omega with a fair value at the date of issue of $551,850.

Concurrent with the acquisition of the equity interests in the MSO, the sole
stockholder of the Company will organize a new company (the orthodontic
practice) that will enter into a 20-year management services agreement with
Omega (or a wholly-owned subsidiary of Omega) renewable for an additional 20
years. The agreement will stipulate that Omega (or a wholly-owned subsidiary of
Omega) provide practice management and marketing services, facilities and
non-clinical personnel to the orthodontic practice for a monthly fee equal to
70% of the orthodontic practice's gross patient fee collections.

The acquisition and related management services agreement are entirely
contingent upon the consummation of an initial public offering by Omega.

                         Report of Independent Auditors


To the Board of Directors
Omega Orthodontics, Inc.


We have audited the accompanying balance sheets of the practice of Dr. Scott E.
Feldman, D.D.S., M.S. (a Proprietorship) as of December 31, 1996 and 1995 and
the related statements of income and proprietor's capital and cash flows for the
years then ended. These financial statements are the responsibility of the
Proprietorship's management. Our responsibility is to express an opinion on
these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the practice of Dr. Scott E.
Feldman, D.D.S., M.S. as of December 31, 1996 and 1995, and the results of its
operations and its cash flows for the years then ended in conformity with
generally accepted accounting principles.

                          Notes to Financial Statements

                                December 31, 1996


1.  Summary of Significant Accounting Policies

Nature of Business

The dental practice of Dr. Scott E. Feldman, D.D.S., M.S., was established as a
sole proprietorship (the Proprietorship) in Woodland Hills, California for the
primary purpose of practicing dentistry.

Revenue Recognition

Revenue is recognized in accordance with the proportional performance method of
accounting for service contracts. Under this method, revenue is recognized as
services are performed and the costs associated therewith are incurred, under
the terms of contractual agreements with each patient. A significant portion,
approximately 25%, of the services are performed in the initial month of the
contract. Billings under each contract, which vary in duration from 12 to 24
months, are made throughout the term of the contract. Provisions are made
currently for all known or anticipated losses from patient receivables and for
loss contracts. Such deductions totaled $4,300 and $4,500 in 1996 and 1995,
respectively. Patient prepayments represent collections from patients or their
insurance companies which are received in advance of the performance of the
related services.

Risks and Uncertainties

Concentration of Credit Risk
- ----------------------------

Financial instruments which subject the Proprietorship to credit risk consists
primarily of patient receivables. The risk with respect to patient receivables
is minimized due to the fact that patients remit a substantial portion of their
contract fee in advance. The Proprietorship does not require collateral, and
credit losses consistently have been within management's expectations.

1.  Summary of Significant Accounting Policies (continued)

Use of Estimates
- ----------------

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statement and the
reported amount of revenues and expenses during the reported period. Actual
results could differ from those estimates.

Orthodontic Supplies and Materials

Orthodontic supplies and materials are expensed as incurred.

Equipment and Improvements

Equipment and improvements are stated at cost. Depreciation expense is provided
using the straight-line method over the estimated useful lives of the assets,
which range from five to seven years. Amortization of leasehold improvements is
provided over the term of the lease or their estimated useful life, whichever is
shorter.

Income Taxes

Income from the Proprietorship is reported in the proprietor's federal and state
income tax return. Accordingly, no income taxes have been recorded in the
Proprietorship's financial statements.

Impairment of Long-Lived Assets

In 1996, the Proprietorship adopted Statement of Financial Accounting Standards
("SFAS") No. 121 "Impairment of Long-Lived Assets and Long-Lived Assets to be
Disposed of". SFAS No. 121 requires recognition of impairment losses on
long-lived assets when indicators of impairment losses on long-lived assets are
present and future undiscounted cash flows are insufficient to support the
assets' recovery. Adoption of SFAS No. 121 had no material impact on the
Proprietorship's financial statements.

3.  Operating Leases

The Proprietorship's office space is rented under a tenant at will agreement.
Rent expense amounted to $28,783 and $27,754 in 1996 and 1995 respectively.

4.    Related Party Transactions

As a sole proprietorship, the accompanying statements of income and proprietor's
capital do not include any compensation for services rendered by the sole
proprietor. Proprietor's withdrawals amounted to $250,914 and $142,853 in 1996
and 1995, respectively.

5.  Contingent Practice Acquisition

The Proprietorship has entered into an agreement with Omega Orthodontics, Inc.
(Omega), a company recently organized to provide management and marketing
services to orthodontic practices in the United States. In the event of a
successful public offering of Omega's common stock, this agreement provides for
the purchase by Omega of the equity interests in a management services
organization (MSO) to be formed by the Proprietor which will hold certain assets
of the Proprietorship. The agreement provides for the payment by Omega of
$527,743, consisting of cash of $175,915, a five-year term 8.5% annual interest
bearing note totaling $82,680 and shares of common stock of Omega with a fair
value at the date of issue of $269,148.

Concurrent with the acquisition of the equity interests in the MSO, the
Proprietor will organize a new company (the orthodontic practice) that will
enter into a 20-year management services agreement with Omega (or a wholly-owned
subsidiary of Omega) renewable for an additional 20 years. The agreement will
stipulate that Omega (or a wholly-owned subsidiary of Omega) provide practice
management and marketing services, facilities and non-clinical personnel to the
orthodontic practice for a monthly fee equal to 65% of the orthodontic
practice's gross patient fee collections.

The acquisition and related management services agreement are entirely
contingent upon the consummation of an initial public offering by Omega.

                         Report of Independent Auditors


To the Board of Directors
Omega Orthodontics, Inc.


We have audited the accompanying balance sheets of the practice of David T.
Grove, D.M.D. (a Proprietorship) as of December 31, 1996 and 1995 and the
related statements of income, proprietor's capital, and cash flows for the years
then ended. These financial statements are the responsibility of the
Proprietorship's management. Our responsibility is to express an opinion on
these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of the practice of David T. Grove,
D.M.D. as of December 31, 1996 and 1995, and the results of its operations and
its cash flows for the years then ended in conformity with generally accepted
accounting principles.

1.  Summary of Significant Accounting Policies

Nature of Business

The dental practice of Dr. David T. Grove (the Proprietorship) was established
in 1986 as a sole proprietorship in Elko, Nevada for the primary purpose of
practicing dentistry.

Revenue Recognition

Revenue is recognized in accordance with the proportional performance method of
accounting for service contracts. Under this method, revenue is recognized as
services are performed and the costs associated therewith are incurred, under
the terms of contractual agreements with each patient. A significant portion,
approximately 25%, of the services are performed in the initial month of the
contract. Billings under each contract, which vary in duration from 12 to 24
months, are made throughout the term of the contract. Provisions are made
currently for all known or anticipated losses from patient receivables and for
loss contracts. Such deductions totaled $8,300 and $7,000 in 1996 and 1995,
respectively. Patient prepayments represent collections from patients or their
insurance companies which are received in advance of the performance of the
related services.

Orthodontic Supplies and Materials

Orthodontic supplies and materials are expensed as incurred.

Cash and Cash Equivalents

The Proprietorship considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents.

Income Taxes

The Proprietorship is organized as a sole proprietorship. Income from the
Proprietorship is reported in the proprietor's federal income tax return.
Accordingly, no income taxes have been recorded in the Proprietorship's
financial statements.

Risks and Uncertainties

Concentration of Credit Risk
- ----------------------------

Financial instruments which subject the Proprietorship to credit risk consist
primarily of accounts receivable. The risk with respect to accounts receivable
is minimized due to the fact that patients remit a substantial portion of their
contract fee in advance. The Proprietorship generally does not require
collateral, and credit losses consistently have been within management's
expectations.

Use of Estimates
- ----------------

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported revenues and expenses during the reporting period. Actual results
could differ from those estimates.

Property, Equipment and Improvements

Property, equipment and improvements are stated at cost. Depreciation expense is
provided using the straight-line method over the estimates useful lives of the
assets, which range from five to forty years. Amortization of assets under
capital lease is provided over the term of the lease or their estimated useful
life, whichever is shorter, and is included with depreciation expense.


Impairment of Long-Lived Assets

In 1996, the Proprietorship adopted Statement of Financial Accounting Standards
(SFAS) No. 121, "Impairment of Long-Lived Assets and Long-Lived Assets to be
Disposed of". SFAS No. 121 requires recognition of impairment losses on
long-lived assets when indicators of impairment losses are present and future
undiscounted cash flows are insufficient to support the assets' recovery.
Adoption of SFAS No. 121 had no material impact on the Proprietorship's
financial statements.

Professional Liability Insurance

The Proprietorship has obtained professional liability coverage through
commercial insurance carriers on a claims-made basis. Management believes that
there are no claims that may result in a loss in excess of amounts covered by
its existing insurance.

2.  Property, Equipment and Improvements

Property, equipment and improvements consisted of the following at December 31:

4.  Capital Leases

The Proprietorship leases its computer system under a capital lease expiring in
1999. The economic substance of the lease, which contains a bargain purchase
option at the end of the lease term, is that the Proprietorship is financing the
acquisition of the assets through the lease and, accordingly, it is recorded in
the Proprietorship's assets and liabilities.

Assets and related accumulated amortization recorded under capital leases
included in the furniture and fixtures category of property, equipment and
improvements are as follows at December 31:

5.  Contingent Practice Acquisition

The Proprietorship has entered into an agreement with Omega Orthodontics, Inc.
(Omega), a company recently organized to provide management and marketing
services to orthodontic practices in the United States. In the event of a
successful public offering of Omega's common stock, this agreement provides for
the purchase by Omega (or a wholly-owned subsidiary of Omega) of certain assets
of the Proprietorship for $1,000,704, consisting of cash of $333,567, a
five-year term 8.5% annual interest bearing note totaling $333,567 and shares of
common stock of Omega with a fair value at the date of issue of $333,570.

Concurrent with the acquisition of certain or the Proprietorship's assets, the
Proprietor will organize a new company (the orthodontic practice) to enter into
a 20-year management services agreement with Omega (or a wholly-owned subsidiary
of Omega), renewable for an additional 20 years. The agreement will stipulate
that Omega (or a wholly-owned subsidiary of Omega) provide practice management
and marketing services, facilities and non-clinical personnel to the orthodontic
practice for a monthly fee equal to 75% of the orthodontic practice's gross
patient fee collections.

The acquisition and related management services agreement are entirely
contingent upon the consummation of an initial public offering by Omega.

                                December 31, 1996


1.  Summary of Significant Accounting Policies

Nature of Business

The dental practice of Theodore G. Saydyk, Jr. D.D.S., M.S., P.C. (the Company)
was incorporated December 1, 1987 in Colorado for the primary purpose of
practicing dentistry.

Revenue Recognition

Revenue is recognized in accordance with the proportional performance method of
accounting for service contracts. Under this method, revenue is recognized as
services are performed and the costs associated therewith are incurred, under
the terms of contractual agreements with each patient. A significant portion,
approximately 25%, of the services are performed in the initial month of the
contract. Billings under each contract, which vary in duration from 12 to 24
months, are made throughout the term of the contract. Provisions are made
currently for all known or anticipated losses from patient receivables and for
loss contracts. Such deductions totaled $10,000 and $16,000 in 1996 and 1995,
respectively. Patient prepayments represent collections from patients or their
insurance companies which are received in advance of the performance of the
related services.

Risks and Uncertainties

Concentration of Credit Risk
- ----------------------------

Financial instruments which subject the Company to credit risk consist primarily
of patient receivables. The risk with respect to patient receivables is
minimized due to the fact that patients remit a substantial portion of their
contract fee in advance. The Company generally does not require collateral, and
credit losses consistently have been within management's expectations.

Use of Estimates
- ----------------

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statement and the
reported amount of revenues and expenses during the reported period. Actual
results could differ from those estimates.

                    Notes to Financial Statements (continued)


1.  Summary of Significant Accounting Policies (continued)

Orthodontic Supplies and Materials

Orthodontic supplies and materials are expensed as incurred.

Equipment and Improvements

Equipment and improvements are stated at cost. Depreciation expense is provided
using the straight-line method over the estimated useful lives of the assets,
which range from five to eleven years. Amortization of leasehold improvements is
provided over the term of the lease or their estimated useful life, whichever is
shorter.

Income Taxes

The Company provides for income taxes under the liability method prescribed by
Statement of Financial Accounting, Standards (SFAS) No. 109, "Accounting for
Income Taxes". Under this method, deferred tax liabilities and assets are
determined based on the difference between the financial statement and tax basis
of assets and liabilities using enacted tax rates in effect for the year in
which the differences are expected to reverse. SFAS No. 109 requires that the
Company record a valuation allowance when it is more likely than not that some
portion or all of the deferred tax assets will not be realized. The Company did
not require a valuation allowance in 1996 or 1995.
The Company prepares its tax returns on the cash basis.

Impairment of Long-Lived Assets

In 1996, the Company adopted Statement of Financial Accounting Standards (SFAS)
No. 121, `Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed
of ". SFAS No. 121 requires recognition of impairment losses on long-lived
assets when indicators of impairment are present and future undiscounted cash
flows are insufficient to support the assets' recovery. Adoption of SFAS No. 121
had no material impact on the Company's financial statements.

Professional Liability Insurance

The Company has obtained professional liability coverage through commercial
insurance carriers on a claims made basis. Management believes that there are no
claims that may result in a loss in excess of amounts covered by its existing
insurance.

7.  Employee Benefit Plan

The Company has a money purchase plan and a profit sharing plan (collectively,
the Plans). All employees who have reached the age of 21 and have completed two
years of service are eligible for the Plans. The Company makes annual
contributions to the money purchase plan based on 5% of employees' eligible
compensation. The Company makes discretionary contributions to the profit
sharing plan which are allocated to the employees based on their percentage of
compensation to the total of all employees' compensation. Plan expense for the
years ended December 31, 1996 and 1995 was $7,374 and $5,011, respectively.

8.  Contingent Practice Acquisition

The Company has entered into an agreement with Omega Orthodontics Inc. (Omega),
a company recently organized to provide management and marketing services to
orthodontic practices in the United States. In the event of a successful public
offering of Omega's common stock, this agreement provides for the purchase by
Omega of the equity interests in a management services organization (MSO) to be
formed by the Company's sole stockholder converting the Company into a general
corporation which will hold certain assets of the Company. The agreement
provides for the payment by Omega of $680,151, consisting of cash of $226,716, a
five-year term 8.5% annual interest bearing note totaling $106,557 and shares of
common stock of Omega with a fair value at the date of issue of $346,878.

Concurrent with the acquisition of the equity interests in the MSO, the sole
stockholder of the Company will organize a new company (the orthodontic
practice) that will enter into a 20-year management services agreement with
Omega (or a wholly-owned subsidiary of Omega) renewable for an additional 20
years. The agreement will stipulate that Omega (or a wholly-owned subsidiary of
Omega) provide practice management and marketing services, facilities and
non-clinical personnel to the orthodontic practice for a monthly fee equal to
75% of the orthodontic practice's gross patient fee collections.

The acquisition and related management services agreement are entirely
contingent upon the consummation of an initial public offering by Omega.

In addition to the above transaction, the Company paid Omega consulting fees in
the amount of $6,000 for the year ended December 31, 1996.

                         Report of Independent Auditors


To the Board of Directors
Omega Orthodontics, Inc.


We have audited the accompanying balance sheets of Robert R. Schmisseur, D.D.S.,
P.C. (the Company) as of December 31, 1996 and 1995 and the related statements
of income and accumulated deficit and cash flows for the years then ended. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Robert R. Schmisseur, D.D.S.,
P.C. as of December 31, 1996 and 1995, and the results of its operations and its
cash flows for the years then ended in conformity with generally accepted
accounting principles.

The accompanying financial statements have been prepared assuming that the
company will continue as a going concern. As discussed in Note 1, the Company a
stockholder's deficit of $152,967, and a working capital deficit of $241,848 at
December 31, 1996. These conditions raise substantial doubt about the Company's
ability to continue as a going concern. Management's plans in regard to these
matters are also described in Note 1. The financial statements do not include
any adjustments to reflect the possible future effects on the recoverability and
classification of assets or the amounts and classification of liabilities that
may result from the outcome of this uncertainty.

1.  Summary of Significant Accounting Policies

Nature of Business

The dental practice of Robert R. Schmisseur, D.D.S., P.C. (the Company) is a
professional corporation which was incorporated February 14, 1985 in Champaign,
Illinois for the primary purpose of practicing dentistry.

Basis of Presentation

The Company's financial statements have been presented on a going concern basis
which contemplates the realization of assets and the satisfaction of liabilities
in the normal course of business. At December 31, 1996, the Company had a
stockholder's deficit of $152,967 and a working capital deficit of $241,848.
Included in total assets is amounts due from stockholder of $64,703 at December
31, 1996.

These conditions indicate that the Company's ability to continue as a going
concern will be dependent upon its ability to generate sufficient cash flow to
meet its liabilities as they become due, including obtaining financing from
outside sources. Management expects to obtain adequate capital from its
contemplated transaction with Omega Orthodontics, Inc. (Omega) (see Note 8).
Should the transaction with Omega not be consummated, management will seek
financing through other sources, however, there can be no assurance that such
sources of capital will be available, on terms and conditions acceptable to the
Company, and that the pending transaction with Omega will be completed. The
financial statements do not include any adjustments to reflect the possibility
of future effects on the classification and recoverability of assets or the
liabilities that might result if the Company were not able to continue as a
going concern in its present form.

                    Notes to Financial Statements (continued)


1.  Summary of Significant Accounting Policies (continued)

Revenue Recognition

Revenue is recognized in accordance with the proportional performance method of
accounting for service contracts. Under this method, revenue is recognized as
services are performed and the costs associated therewith are incurred, under
the terms of contractual agreements with each patient. A significant portion,
approximately 25%, of the services are performed in the initial month of the
contract. Billings under each contract, which vary in duration from 12 to 24
months, are made throughout the term of the contract. Provisions are made
currently for all known or anticipated losses from patient receivables and for
loss contracts. Such deductions totaled $5,900 and $5,400 in 1996 and 1995,
respectively. Patient prepayments represent collections from patients or their
insurance companies which are received in advance of the performance of the
related services.

Risks and Uncertainties

Concentration of Credit Risk
- ----------------------------

Financial instruments which subject the Company to credit risk consists
primarily of patient receivables. The risk with respect to patient receivable is
minimized due to the fact that patients remit a substantial portion of their
contract fee in advance. The Company generally does not require collateral, and
credit losses consistently have been within management's expectations.

Use of Estimates
- ----------------

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statement and the
reported amount of revenues and expenses during the reported period. Actual
results could differ from those estimates.

1.  Summary of Significant Accounting Policies (continued)

Orthodontic Supplies and Materials

Orthodontic supplies and materials are expensed as incurred.

Equipment and Improvements

Equipment and improvements are stated at cost. Depreciation expense is provided
using the straight-line method over the estimated useful lives of the assets,
which range from five to seven years. Amortization of leasehold improvements is
provided over the term of the lease or their estimated useful life, whichever is
shorter.

Income Taxes

The Company provides for income taxes under the liability method prescribed by
Statement of Financial Accounting, Standards (SFAS) No. 109, "Accounting for
Income Taxes". Under this method, deferred tax liabilities and assets are
determined based on the difference between the financial statement and tax basis
of assets and liabilities using enacted tax rates in effect for the year in
which the differences are expected to reverse. SFAS No. 109 requires that the
Company record a valuation allowance when it is more likely than not that some
portion or all of the deferred tax assets will not be realized. Due to the
uncertainty of the Company's ability to realize the benefit of the deferred tax
assets, a full valuation allowance has been applied against the net deferred tax
assets in 1996 and 1995. The Company prepares its tax returns on the cash basis.

Impairment of Long-Lived Assets

In 1996, the Company adopted Statement of Financial Accounting Standards (SFAS)
No. 121 "Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed
Of". SFAS No. 121 requires recognition of impairment losses on long-lived assets
when indicators of impairment losses on long-lived assets are present and future
undiscounted cash flows are insufficient to support the assets' recovery.
Adoption of SFAS No. 121 had no material impact on the Company's financial
statements.

The effective tax rate for 1996 and 1995 (0%) differed from the statutory tax
rate (34%) due to the decrease in the valuation allowance. The Company had net
operating loss carryforwards of approximately $37,500 at December 31, 1996,
which expire in the year 1999.

6.  Leases

The Company's office space is rented under a three year operating lease which
expires on February 28, 1997. The lease contains a renewal option which allows
the Company to renew the lease three times, each for a period of three years,
resulting in a maximum expiration date of February 2006. On February 7, 1997,
the Company exercised its renewal option effective March 1, 1997 extending the
lease through February 28, 2000.

Total rent expense for the years ended December 31, 1996 and 1995 amounted to
$27,556 and $25,472, respectively. Future minimum lease payments are as follows:

Year ending December 31:
   1997                                         $28,290

7.  Defined Contribution Plan

The Company's defined contribution plan (the Plan) covers employees that meet
the Plan's eligibility requirements. The Plan provides for employee
contributions. The Company may also make contributions to the Plan at the
discretion of the Board of Directors. The Company made matching contributions of
$21,314 in 1995. Effective January 1, 1996, the Plan was terminated. Although
the Company has filed for termination of the Plan with the appropriate
regulatory agencies, no formal termination approval has been received.

8.  Contingent Practice Acquisition

The Company has entered into an agreement with Omega, a company recently
organized to provide management and marketing services to orthodontic practices
in the United States. In the event of a successful public offering of Omega's
common stock, this agreement provides for the purchase by Omega of the equity
interests in a management services organization (MSO) to be formed by the
Company's sole stockholder converting the Company into a general corporation
which will hold certain assets of the Company. The agreement provides for the
payment by Omega of $654,124, consisting of cash of $218,042, a five-year term
8.5% annual interest bearing note totaling $218,042 and shares of common stock
of Omega with a fair value at the date of issue of $218,040.

Concurrent with the acquisition of the equity interests in the MSO, the sole
stockholder of the Company will organize a new company (the orthodontic
practice) that will enter into a 20-year management services agreement with
Omega (or a wholly-owned subsidiary of Omega), renewable for an additional 20
years. The agreement will stipulate that Omega (or a wholly-owned subsidiary of
Omega) provide practice management and marketing services, facilities and
non-clinical personnel to the orthodontic practice for a monthly fee equal to
75% of the orthodontic practice's gross patient fee collections.

The acquisition and related management services agreement are entirely
contingent upon the consummation of an initial public offering by Omega.

                         Report of Independent Auditors


To the Board of Directors
Omega Orthodontics, Inc..


We have audited the accompanying balance sheets of Clark E. Schneekluth, D.D.S.,
M.D., Inc. (the Company) as of December 31, 1996 and 1995 and the related
statements of operations and accumulated deficit and cash flows for the years
then ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Clark E. Schneekluth, D.D.S.,
M.D., Inc. as of December 31, 1996 and 1995, and the results of its operations
and its cash flows for the years then ended in conformity with generally
accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1, the Company
had a net loss of $5,452 for the year ended December 31, 1996, a stockholder's
deficit of $91,143, and a working capital deficit of $91,062 at December 31,
1996. These conditions raise substantial doubt about the Company's ability to
continue as a going concern. Management's plans in regard to these matters are
also described in Note 1. The financial statements do not include any
adjustments to reflect the possible future effects on the recoverability and
classification of assets or the amounts and classification of liabilities that
may result from the outcome of this uncertainty.

                          Notes to Financial Statements

                                December 31, 1996


1.  Summary of Significant Accounting Policies

Nature of Business

The dental practice of Clark E. Schneekluth D.D.S., M.D., Inc. (the Company) is
a professional corporation which was incorporated October 15, 1985 in the state
of California for the primary purpose of practicing dentistry.

Basis of Presentation

The Company's financial statements have been presented on a going concern basis
which contemplates the realization of assets and the satisfaction of liabilities
in the normal course of business. For the year ended December 31, 1996 the
Company incurred a net loss of $5,452. At December 31, 1996, the Company had a
stockholder's deficit of $91,143 and a working capital deficit of $91,062.

These conditions indicate that the Company's ability to continue as a going
concern will be dependent upon its ability to generate sufficient cash flow to
meet its liabilities as they become due, including obtaining financing from
outside sources. Management expects to obtain adequate capital from its
contemplated transaction with Omega Orthodontics, Inc. (Omega) (see Note 6).
Should the transaction with Omega not be consummated, management will seek
financing through other sources, however, there can be no assurance that such
sources of capital will be available, on terms and conditions acceptable to the
Company, and that the pending transaction with Omega will be completed. The
financial statements do not include any adjustments to reflect the possibility
of future effects on the classification and recoverability of assets or the
liabilities that might result if the Company were not able to continue as a
going concern in its present form.

1.  Summary of Significant Accounting Policies (continued)

Revenue Recognition

Revenue is recognized in accordance with the proportional performance method of
accounting for service contracts. Under this method, revenue is recognized as
services are performed and the costs associated therewith are incurred, under
the terms of contractual agreements with each patient. A significant portion,
approximately 25%, of the services are performed in the initial month of the
contract. Billings under each contract, which vary in duration from 12 to 24
months, are made throughout the term of the contract. Provisions are made
currently for all known or anticipated losses from patient receivables and for
loss contracts. Such deductions totaled $29,556 and $32,774 in 1996 and 1995,
respectively. Patient prepayments represent collections from patients or their
insurance companies which are received in advance of the performance of the
related services.

Risks and Uncertainties

Concentration of Credit Risk
- ----------------------------

Financial instruments which subject the Company to credit risk consist primarily
of patients receivable. The risk with respect to patients receivable is
minimized due to the fact that patients remit a substantial portion of their
contract fee in advance. The Company generally does not require collateral, and
credit losses consistently have been within management's expectations.

Use of Estimates
- ----------------

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statement and the
reported amount of revenues and expenses during the reported period. Actual
results could differ from those estimates.

Orthodontic Supplies and Materials

Orthodontic supplies and materials are expensed as incurred.

1.  Summary of Significant Accounting Policies (continued)

Equipment and Improvements

Equipment and improvements are stated at cost. Depreciation expense is provided
using the straight-line method over the estimated useful lives of the assets,
which range from five to seven years. Amortization of leasehold improvements is
provided over the term of the lease or their estimated useful life, whichever is
shorter.

Income Taxes

The Company has elected to be taxed under the provision of Subchapter S of the
Internal Revenue Code. Under those provisions, the Company does not pay federal
corporate income taxes on its taxable income. Instead, the stockholder is liable
for individual federal income taxes on the corporate income. Accordingly, no
provision has been made for federal income tax in the accompanying financial
statements. The Company prepares its tax returns on the cash basis.

Impairment of Long-Lived Assets

In 1996, the Company adopted Statement of Financial Accounting Standards (SFAS)
No. 121, "Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed
of". SFAS No. 121 requires recognition of impairment losses on long-lived assets
when indicators of impairment are present and future undiscounted cash flows are
insufficient to support the assets' recovery. Adoption of SFAS No. 121 had no
material impact on the Company's financial statements.

Professional Liability Insurance

The Company has obtained professional liability coverage through commercial
insurance carriers on a claims-made basis. Management believes that there are no
claims that may result in a loss in excess of amounts covered by its existing
insurance.

3.  Related Party Transaction

The sole stockholder received approximately $39,000 and $40,000 of compensation
from the Company in 1996 and 1995, respectively, which is included in employee
costs. Stockholder's distribution amounted to $47,470 and $39,486 in 1996 and
1995, respectively. Additionally, the Company has a non-interest bearing note
payable, due on demand, amounting to $15,000 and $10,000 at December 31, 1996
and 1995, respectively, with PRO Inc., a related party.

In January and February, 1997, the Company incurred additional borrowings
totaling $10,950 from PRO Inc. Borrowings bear interest at 10% per annum and are
due within 180 days from date of issuance.

6. Contingent Practice Acquisition

The Company has entered into an agreement with Omega, a company recently
organized to provide management and marketing services to orthodontic practices
in the United States. In the event of a successful public offering of Omega's
common stock, this agreement provides for the purchase by Omega of the equity
interests in a management services organization (MSO) to be formed by the
Company's sole stockholder converting the Company into a general corporation
which will hold certain assets of the Company. The agreement provides for the
payment by Omega of $342,048, consisting of cash of $114,016, a five-year term
8.5% annual interest bearing note totaling $53,588 and shares of common stock of
Omega with a fair value at the date of issue of $174,444.

Concurrent with the acquisition of the equity interests in the MSO, the sole
stockholder of the Company will organize a new company (the orthodontic
practice) that will enter into a 20-year management services agreement with
Omega (or a wholly-owned subsidiary of Omega) renewable for an additional 20
years. The agreement will stipulate that Omega (or a wholly-owned subsidiary of
Omega) provide practice management and marketing services, facilities and
non-clinical personnel to the orthodontic practice for a monthly fee equal to
75% of the orthodontic practice's gross patient fee collections.

The acquisition and related management services agreement are entirely
contingent upon the consummation of an initial public offering by Omega.

1.  Summary of Significant Accounting Policies

Nature of Business

The dental practice of Jeff S. Zapalac, D.D.S., M.S., Inc. (the Company) is a
professional corporation which was incorporated September 9, 1981 in Austin,
Texas for the primary purpose of practicing dentistry.

Revenue Recognition

Revenue is recognized in accordance with the proportional performance method of
accounting for service contracts. Under this method, revenue is recognized as
services are performed and the costs associated therewith are incurred, under
the terms of contractual agreements with each patient. A significant portion,
approximately 25%, of the services are performed in the initial month of the
contract. Billings under each contract, which vary in duration from 12 to 24
months, are made throughout the term of the contract. Provisions are made
currently for all known or anticipated losses from patient receivables and for
loss contracts. Such deductions totaled $10,000 and $3,000 in 1996 and 1995,
respectively. Patient prepayments represent collections from patients or their
insurance companies which are received in advance of the performance of the
related services.

Risks and Uncertainties

Concentration of Credit Risk
- ----------------------------

Financial instruments which subject the Company to credit risk consists
primarily of patient receivables. The risk with respect to patient receivables
is minimized due to the fact that patients remit a substantial portion of their
contract fee in advance. The Company performs periodic credit evaluations of its
patients' financial condition and generally does not require collateral. Credit
losses consistently have been within management's expectations.

1.  Summary of Significant Accounting Policies (continued)

Use of Estimates
- ----------------

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statement and the
reported amount of revenues and expenses during the reported period. Actual
results could differ from those estimates.

Orthodontic Supplies and Materials

Orthodontic supplies and materials are expensed as incurred.

Equipment and Improvements

Equipment and improvements are stated at cost. Depreciation expense is provided
using the straight-line method over the estimated useful lives of the assets.
Amortization of leasehold improvements is provided over the term of the lease or
their estimated useful life, whichever is shorter.

Professional Liability Insurance

The Company has obtained professional liability coverage through commercial
insurance carriers on an occurrence basis. Management believes that there are no
claims that may result in a loss in excess of amounts covered by its existing
insurance.

Income Taxes

The Company provides for income taxes under the liability method prescribed by
Statement of Financial Accounting, Standards (SFAS) No. 109, "Accounting for
Income Taxes". Under this method, deferred tax liabilities and assets are
determined based on the difference between the financial statement and tax basis
of assets and liabilities using enacted tax rates in effect for the year in
which the differences are expected to reverse. SFAS No. 109 requires that the
Company record a valuation allowance when it is more likely than not that some
portion or all of the deferred tax assets will not be realized. Due to the
uncertainty of the Company's ability to realize the benefit of the deferred tax
assets, a full valuation allowance has been applied against the net deferred tax
assets in 1996 and 1995. The Company prepares its tax returns on the cash basis.

Impairment of Long-Lived Assets

In 1996, the Company adopted Statement of Financial Accounting Standards
("SFAS") No. 121 "Impairment of Long-Lived Assets and Long-Lived Assets to be

long-lived assets when indicators of impairment losses on long-lived assets are

rate differs from the statutory tax rate due to the timing of cash receipts and
disbursements.

7.   Profit Sharing Plan

The Company has a profit sharing plan (the Plan) that covers all employees
meeting defined eligibility requirements. Contributions are at the discretion of
management. Total contributions to the Plan charged to operations were
approximately $27,000 and $26,000 in 1996 and 1995, respectively.

8.  Contingent Practice Acquisition

The Company has entered into an agreement with Omega Orthodontics, Inc. (Omega),
a company recently organized to provide management and marketing services to
orthodontic practices in the United States. In the event of a successful public
offering of Omega's common stock, this agreement provides for the purchase of by
Omega of the equity interests in a management services organization (MSO) to be
formed by the Company's sole stockholder converting the Company into a general
corporation which will hold certain assets of the Company. The agreement
provides for the payment by Omega of $500,000 which will be paid in cash. In
addition, the sole stockholder of the Company will receive an option to purchase
$500,000 of shares of common stock of Omega at the fair value at the date of
issuance.

8.  Contingent Practice Acquisition (continued)

Concurrent with the acquisition of the equity interests in the MSO, the sole
stockholder of the Company will organize a new company (the orthodontic
practice) that will enter into a 20-year management services agreement with
Omega (or a wholly-owned subsidiary of Omega) renewable for an additional 20
years. The agreement will stipulate that Omega (or a wholly-owned subsidiary of
Omega) provide practice management and marketing services, facilities and
non-clinical personnel to the orthodontic practice for a monthly fee equal to
75% of the orthodontic practice's gross patient fee collections.

The acquisition and related management services agreement are entirely
contingent upon the consummation of an initial public offering by Omega.

                                    PART II

                    INFORMATION NOT REQUIRED IN PROSPECTUS

Item 24. Indemnification of Directors and Officers

     The Company is a Delaware corporation. Reference is made to Section 145 of
the Delaware General Corporation Law, as amended, which provides that a
corporation may indemnify any person who was or is a party to or is threatened
to be made a party to any threatened, pending or completed action, suit or
proceeding whether civil, criminal, administrative or investigative (other than
an action by or in the right of the corporation) by reason of the fact that such
person is or was a director, officer, employee or agent of the corporation, or
is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against expenses (including attorneys' fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with such action, suit or proceeding if such person acted in good
faith and in a manner such person reasonably believed to be in or not opposed to
the best interests of the corporation and, with respect to any criminal action
or proceedings, had no reasonable cause to believe such person's conduct was
unlawful. Section 145 further provides that a corporation similarly may
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that such
person is or was a director, officer, employee or agent of the corporation, or
is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, against expenses (including attorneys' fees) actually and
reasonably incurred by such person in connection with the defense or settlement
of such action or suit if such person acted in good faith and in a manner such
person reasonably believed to be in or not opposed to the best interests of the
corporation and except that no indemnification shall be made in respect to any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Delaware Court
of Chancery or the court in which such action or suit was brought shall
determine upon application that, despite an adjudication of liability, but in
view of all the circumstances of the case, such person is fairly and reasonably
entitled to indemnity for such expenses which the Court of Chancery or such
other court shall deem proper.

     Article Sixth of the Company's Certificate of Incorporation, as amended,
eliminates the personal liability of directors to the Company or its
stockholders for monetary damages for breach of fiduciary duty to the full
extent permitted by Delaware law. Article VII of the Company's By-Laws provides
that the Company shall indemnify its officers and directors to the full extent
permitted by the Delaware General Corporation Law. Under the Company's By-Laws,
a director or officer will not receive indemnification if such director or
officer is found not to have acted in good faith and in a manner such director
or officer reasonably believed to be in or not opposed to the best interests of
the Company.

     The Company maintains an indemnification insurance policy covering all
directors and officers of the Company and its subsidiaries.

Item 26. Recent Sales of Unregistered Securities

     The securities issued in the following transactions were not registered
under the Securities Act in reliance upon the exemptions from registration set
forth in Section 3(b) and/or 4(2) of the Securities Act and the rules and
regulation promulgated thereunder.

     On August 31, 1996, Omega issued, in a private transaction, 1,050,000
shares of its Common Stock to The Orthodontic Management Effectiveness Group of
America, LLC ("OMEGA, LLC") in exchange for OMEGA, LLC's orthodontic practice
management business and certain related assets and agreements. Messrs. Schulhof,
Glovsky, Grove and Bellavia, all of the then directors of Omega, held in the
aggregate, at the time of the issuance, in excess of 50% of the membership
points of OMEGA, LLC. Omega relied on Section 4(2) of the Securities Act and the
rules and regulations promulgated thereunder in issuing these securities without
registration under the Securities Act.

     Pursuant to an agreement among Omega, Dr. Glovsky, the Chairman of the
Board, and The Mayflower Group, Ltd., a private banking firm and a holder of in
excess of five percent of the membership points of OMEGA, LLC ("Mayflower"), as
amended and restated, Omega issued 225,000 shares of its Common Stock to each of
Dr. Glovsky and Mayflower in consideration of certain consulting services
rendered by Dr. Glovsky and Mayflower to Omega. Omega relied on Section 4(2) of
the Securities Act and the rules and regulations promulgated thereunder in
issuing these securities without registration under the Securities Act.

     During September, October and November 1996 and February and April 1997,
Omega privately placed $875,000 of its 15% Senior Notes due September 30, 1997
(the "Bridge Notes") along with 175,000 shares of its Common Stock with a group
of "accredited investors," as that term is defined in Rule 501 promulgated under
the Securities Act. The total consideration received by Omega for these
securities was $875,000. Omega relied on Section 4(2) of the Securities Act and
the rules and regulations promulgated thereunder in issuing these securities
without registration under the Securities Act.

     In April 1997, Omega issued 10,000 shares of its Common Stock to Leonard,
Mulherin & Greene, P.C., a public accounting firm ("LMG"), in partial
consideration for consulting services provided by LMG to Omega. Omega's Chief
Financial Officer is a principal stockholder of LMG. Omega relied on Section
4(2) of the Securities Act and the rules and regulations promulgated thereunder
in issuing these securities without registration under the Securities Act.

Item 28. Undertakings

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the small business issuer pursuant to the foregoing provisions, or
otherwise, the small business issuer has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the small business issuer of expenses incurred or paid by a director, officer or
controlling person of the small business issuer in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the small business
issuer will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

     The small business issuer will:

     (1) For determining any liability under the Securities Act, treat the
information omitted from the form of prospectus filed as part of this
registration statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the small business issuer under Rule 424(b)(1), or (4), or
497(h) under the Securities Act as part of this registration statement as of the
time the Commission declared it effective.

     (2) For determining any liability under the Securities Act, treat each
post-effective amendment that contains a form of prospectus as a new
registration statement for the securities offered in the registration statement,
and that the offering of the securities at that time as the initial bona fide
offering of those securities.

     The small business issuer will provide to the underwriter at the closing
specified in the underwriting agreement, certificates in such denominations and
registered in such names as required by the underwriter to permit prompt
delivery to each purchaser.

     The small business issuer will:

     (1) File, during any period in which it offers or sells securities, a
post-effective amendment to this registration statement to:

       (i) Include any prospectus required by Section 10(a)(3) of the Securities
   Act;

       (ii) Reflect in the prospectus any fact or events which, individually or
   together, represent a fundamental change in the information in the
   registration statement. Notwithstanding the foregoing, any increase or
   decrease in volume of securities offered (if the total dollar value of
   securities offered would not exceed that which was registered) and any
   deviation from the low or high end of the estimated maximum offering range
   may be reflected in the form of prospectus filed with the Commission pursuant
   to Rule 424(b) if, in the aggregate, the changes in volume and price
   represent no more than a 20 percent change in the maximum aggregate offering
   price set forth in the "Calculation of Registration Fee" table in the
   effective registration statement.

       (iii) Include any additional or changed material information on the plan
   of distribution.

     (2) For determining liability under the Securities Act, treat each
post-effective amendment as a new registration statement of the securities
offered, and the offering of the securities at that time to be the initial bona
fide offering.

     (3) File a post-effective amendment to remove from registration any of the
securities that remain unsold at the end of the offering.

NATIONAL SECURITIES CORPORATION
  As Representative of the
  Several Underwriters listed on Schedule A hereto
1001 Fourth Avenue
Suite 2200
Seattle, Washington  98154

Ladies and Gentlemen:

        Omega Orthodontics, Inc., a Delaware corporation (the "Company"),
confirms its agreement with National Securities Corporation ("National") and
each of the underwriters named in Schedule A hereto (collectively, the
"Underwriters," which term shall also include any underwriter substituted as
hereinafter provided in Section 11), for whom National is acting as
representative (in such capacity, National shall hereinafter be referred to as
"you" or the "Representative"), with respect to the sale by the Company and the
purchase by the Underwriters, acting severally and not jointly, of the
respective numbers of shares ("Shares") of the Company's common stock, $.01 par
value per share ("Common Stock"), and redeemable common stock purchase warrants
(the "Redeemable Warrants"), each to purchase one share of Common Stock, set
forth in Schedule A hereto. The aggregate 1,800,000 Shares and 1,800,000
Redeemable Warrants will be separately tradeable upon issuance and are
hereinafter referred to as the "Firm Securities." Each Redeemable Warrant is
exercisable commencing on ____________, 1998 [12 months from the date of this
Agreement] until ____________, 2002 [60 months from the date of this Agreement],
unless


<PAGE>


previously redeemed by the Company, at an initial exercise price of $_______
[110% of the initial public offering price] per share of Common Stock. The
Redeemable Warrants may be redeemed by the Company at a redemption price of $.10
per Redeemable Warrant at any time after _____________, 1998 [18 months from the
date of this Agreement] on thirty (30) days' prior written notice, provided that
the closing bid price of the Common Stock equals or exceeds $_______________
[200% of the initial public offering price of Common Stock] per share, for any
twenty (20) trading days within a period of thirty (30) consecutive trading days
ending on the fifth trading day prior to the notice of redemption, all in
accordance with the terms and conditions of the Warrant Agreement (herein
defined).

        Upon your request, as provided in Section 2(b) of this Agreement, the
Company shall also issue and sell to the Underwriters, acting severally and not
jointly, up to an additional 270,000 shares of Common Stock and/or 270,000
Redeemable Warrants for the purpose of covering over-allotments, if any. Such
270,000 shares of Common Stock and 270,000 Redeemable Warrants are hereinafter
collectively to as the "Option Securities." The Company also proposes to issue
and sell to you warrants (the "Representative's Warrants") pursuant to the
Representative's Warrant Agreement (the "Representative's Warrant Agreement")
for the purchase of an additional 180,000 shares of Common Stock and/or 180,000
Redeemable Warrants. The shares of Common Stock and Redeemable Warrants issuable
upon exercise of the Representative's Warrants are hereinafter referred to as
the "Representative's Securities." The Firm Securities, the Option Securities,
the Representative's Warrants and the Representative's Securities (collectively,
hereinafter referred to as the "Securities") are more fully described in the
Registration Statement and the Prospectus referred to below.

        1. Representations and Warranties of the Company. The Company represents
and warrants to, and agrees with, each of the Underwriters as of the date
hereof, and as of the Closing Date (as hereinafter defined) and each Option
Closing Date (as hereinafter defined), if any, as follows:

              (a) The Company has prepared and filed with the Securities and
Exchange Commission (the "Commission") a registration statement, and an
amendment or amendments thereto, on Form SB-2 (No. 333-_________), including any
related preliminary prospectus ("Preliminary Prospectus"), for the registration
of the Firm Securities, the Option Securities and the Representative's
Securities under the Securities Act of 1933, as amended (the "Act"), which
registration statement and amendment or amendments have been prepared by the
Company in conformity with the requirements of the Act, and the rules and
regulations (the "Regulations") of the Commission under the Act. The Company
will promptly file a further amendment to said registration statement in the
form heretofore delivered to the Underwriters and will not file any other
amendment thereto to which the Underwriters shall have objected in writing after
having been furnished with a copy thereof. Except as the context may otherwise
require, such registration statement, as amended, on file with the Commission at
the time the registration statement becomes effective (including the prospectus,
financial statements, schedules, exhibits and all other documents filed as a
part thereof or incorporated therein (including, but not limited to those
documents or information incorporated by reference therein) and all information
deemed to be a part thereof as of such time pursuant to paragraph (b) of Rule
430(A) of the Regulations), is hereinafter called the "Registration Statement",
and the form of prospectus in the form first filed

<PAGE>


with the Commission pursuant to Rule 424(b) of the Regulations, is hereinafter
called the "Prospectus." For purposes hereof, "Rules and Regulations" mean the
rules and regulations adopted by the Commission under either the Act or the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), as applicable.

              (b) Neither the Commission nor any state regulatory authority has
issued any order preventing or suspending the use of any Preliminary Prospectus,
the Registration Statement or Prospectus or any part of any thereof and no
proceedings for a stop order suspending the effectiveness of the Registration
Statement or any of the Company's securities have been instituted or are pending
or threatened. Each of the Preliminary Prospectus, the Registration Statement
and Prospectus at the time of filing thereof conformed with the requirements of
the Act and the Rules and Regulations, and none of the Preliminary Prospectus,
the Registration Statement or Prospectus at the time of filing thereof contained
an untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading, except
that this representation and warranty does not apply to statements made in
reliance upon and in conformity with written information furnished to the
Company with respect to the Underwriters by or on behalf of the Underwriters
expressly for use in such Preliminary Prospectus, Registration Statement or
Prospectus or any amendment thereof or supplement thereto.

              (c) When the Registration Statement becomes effective and at all
times subsequent thereto up to the Closing Date (as defined herein) and each
Option Closing Date (as defined herein), if any, and during such longer period
as the Prospectus may be required to be delivered in connection with sales by
the Underwriters or a dealer, the Registration Statement and the Prospectus will
contain all statements which are required to be stated therein in accordance
with the Act and the Rules and Regulations, and will conform to the requirements
of the Act and the Rules and Regulations; neither the Registration Statement nor
the Prospectus, nor any amendment or supplement thereto, will contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, provided, however,
that this representation and warranty does not apply to statements made or
statements omitted in reliance upon and in strict conformity with information
furnished to the Company in writing by or on behalf of any Underwriter expressly
for use in the Preliminary Prospectus, Registration Statement or Prospectus or
any amendment thereof or supplement thereto.

              (d) Each of the Company and Michael G. Churash, D.D.S., M.S., Ltd.
("Churash"), Theodore G. Saydyk, Jr. D.D.S., M.S., P.C. ("Saydyk"), Robert G.
Schmisseur, D.D.S., M.S., P.C. ("Schmisseur"), Clark E. Schneekluth, D.D.S.,
M.D., Inc. ("Schneekluth"), Jeff S. Zapalac, D.D.S., M.S., Inc. ("Zapalac") and
Marshall D. Spoto, D.D.S., P.A. ("Spoto") has been duly organized and is validly
existing as a corporation in good standing under the laws of the state of its
incorporation. Churash, Saydyk, Schmisseur, Schneekluth, Zapalac, Spoto and the
orthodontic practices of Dr. Scott E. Feldman, D.D.S., M.S. ("Feldman") and
David T. Grove, D.M.D. ("Grove") are hereinafter referred to individually as a
"Subsidiary" and collectively as the "Subsidiaries." Churash, Saydyk,
Schmisseur, Schneekluth, Zapalac and Spoto are hereinafter referred to
collectively as the "Corporate Practices." Except as set forth in the
Prospectus, none of the Company nor the Subsidiaries owns an interest in any
corporation, partnership, trust, joint

                                       3

<PAGE>


venture or other business entity. Each of the Company and the Corporate
Practices is duly qualified and licensed and in good standing as a foreign
corporation in each jurisdiction in which its ownership or leasing of any
properties or the character of its operations requires such qualification or
licensing. Each of the Company and the Subsidiaries has all requisite power and
authority (corporate and other), and has obtained any and all necessary
authorizations, approvals, orders, licenses, certificates, franchises and
permits of and from all governmental or regulatory officials and bodies
(including, without limitation, those having jurisdiction over environmental or
similar matters), to own or lease its properties and conduct its business as
described in the Prospectus; each of the Company and the Subsidiaries is and has
been doing business in compliance with all such authorizations, approvals,
orders, licenses, certificates, franchises and permits and all applicable
federal, state, local and foreign laws, rules and regulations; and none of the
Company nor the Subsidiaries has received any notice of proceedings relating to
the revocation or modification of any such authorization, approval, order,
license, certificate, franchise, or permit which, singly or in the aggregate, if
the subject of an unfavorable decision, ruling or finding, would materially and
adversely affect the condition, financial or otherwise, or the earnings,
position, prospects, value, operation, properties, business or results of
operations of the Company or the Subsidiaries. The disclosures in the
Registration Statement concerning the effects of federal, state, local, and
foreign laws, rules and regulations on the Company's and the Subsidiaries'
businesses as currently conducted and as contemplated are correct in all
material respects and do not omit to state a material fact required to be stated
therein or necessary to make the statements contained therein not misleading in
light of the circumstances under which they were made.

              (e) The Company has a duly authorized, issued and outstanding
capitalization as set forth in the Prospectus under "Capitalization" and
"Description of Securities" and will have the adjusted capitalization set forth
therein on the Closing Date and each Option Closing Date, if any, based upon the
assumptions set forth therein, and the Company is not a party to or bound by any
instrument, agreement or other arrangement providing for it to issue any capital
stock, rights, warrants, options or other securities, except for this Agreement,
the Warrant Agreement, the Representative's Warrant Agreement and as described
in the Prospectus. The Securities and all other securities issued or issuable by
the Company conform or, when issued and paid for, will conform, in all respects
to all statements with respect thereto contained in the Registration Statement
and the Prospectus. All issued and outstanding securities of the Company have
been duly authorized and validly issued and are fully paid and non-assessable
and the holders thereof have no rights of rescission with respect thereto, and
are not subject to personal liability by reason of being such holders; and none
of such securities were issued in violation of the preemptive rights of any
holders of any security of the Company or similar contractual rights granted by
the Company. The Securities are not and will not be subject to any preemptive or
other similar rights of any stockholder, have been duly authorized and, when
issued, paid for and delivered in accordance with the terms hereof, will be
validly issued, fully paid and non-assessable and will conform to the
description thereof contained in the Prospectus; the holders thereof will not be
subject to any liability solely as such holders; all corporate action required
to be taken for the authorization, issue and sale of the Securities has been
duly and validly taken; and the certificates representing the Securities will be
in due and proper form. Upon the issuance and delivery pursuant to the terms
hereof of the Securities to be sold by the Company hereunder, the Underwriters
or the Representative, as the case may be, will acquire good and marketable
title to


                                       4
<PAGE>


such Securities free and clear of any lien, charge, claim, encumbrance, pledge,
security interest, defect or other restriction or equity of any kind whatsoever.

              (f) The financial statements of the Company and the Subsidiaries,
together with the related notes and schedules thereto, included in the
Registration Statement, each Preliminary Prospectus and the Prospectus fairly
present the financial position, income, changes in cash flow, changes in
stockholders' equity and the results of operations of the Company and the
Subsidiaries at the respective dates and for the respective periods to which
they apply and such financial statements have been prepared in conformity with
generally accepted accounting principles and the Rules and Regulations,
consistently applied throughout the periods involved and such financial
statements as are audited have been examined by Ernst & Young, LLP, who are
independent certified public accountants within the meaning of the Act and the
Rules and Regulations, as indicated in their reports filed therewith. There has
been no adverse change or development involving a prospective adverse change in
the condition, financial or otherwise, or in the earnings, position, prospects,
value, operation, properties, business, or results of operations of the Company
and each of the Subsidiaries, whether or not arising in the ordinary course of
business, since the date of the financial statements included in the
Registration Statement and the Prospectus and the outstanding debt, the
property, both tangible and intangible, and the business of the Company and the
Subsidiaries, conform in all material respects to the descriptions thereof
contained in the Registration Statement and the Prospectus. Financial
information set forth in the Prospectus under the headings "Summary Financial
Data," "Selected Consolidated Financial Data," "Capitalization," and
"Management's Plan of Operation," fairly present, on the basis stated in the
Prospectus, the information set forth therein, and have been derived from or
compiled on a basis consistent with that of the audited financial statements
included in the Prospectus. The pro forma financial statements of the Company
and the Subsidiaries, and the related notes thereto, set forth in the
Registration Statement and the Prospectus, have been prepared in conformity with
the requirements of the Act and the Rules and Regulations and present fairly the
information shown therein; and the pro forma adjustments on such pro forma
financial statements have been properly applied on the basis described in the
related notes thereto. The pro forma financial data set forth in the Prospectus
have been prepared on a basis consistent with the pro forma financial statements
of the Company and the Subsidiaries. The amounts shown as accrued for current
and deferred income and other taxes in such financial statements are sufficient
for the payment of all accrued and unpaid federal, state, local and foreign
income taxes, interest, penalties, assessments or deficiencies applicable to the
Company and the Subsidiaries, whether disputed or not, for the applicable period
then ended and periods prior thereto; adequate allowance for doubtful accounts
has been provided for unindemnified losses due to the operations of the Company
and the Subsidiaries; and the statements of income do not contain any items of
special or nonrecurring income not earned in the ordinary course of business,
except as specified in the notes thereto.

              (g) Each of the Company and the Subsidiaries (i) has paid all
federal, state, local, and foreign taxes for which it is liable, including, but
not limited to, withholding taxes and amounts payable under Chapters 21 through
24 of the Internal Revenue Code of 1986, as amended (the "Code"), and has
furnished all information returns it is required to furnish pursuant to the
Code, (ii) has established adequate reserves for such taxes which are not due
and payable, and (iii) does not have any tax deficiency or claims outstanding,
proposed or assessed against it.


                                       5
<PAGE>


              (h) No transfer tax, stamp duty or other similar tax is payable by
or on behalf of the Underwriters in connection with (i) the issuance by the
Company of the Securities, (ii) the purchase by the Underwriters of the Firm
Securities and the Option Securities from the Company and the purchase by the
Representative of the Representative's Warrants from the Company, (iii) the
consummation by the Company of any of its obligations under this Agreement, or
(iv) resales of the Firm Securities and the Option Securities in connection with
the distribution contemplated hereby.

              (i) Each of the Company and the Subsidiaries maintains insurance
policies, including, but not limited to, general liability, malpractice and
property insurance, which insures each of the Company, the Subsidiaries and
their respective employees, against such losses and risks generally insured
against by comparable businesses. None of the Company nor the Subsidiaries (A)
has failed to give notice or present any insurance claim with respect to any
matter, including but not limited to the Company's business, property or
employees, under any insurance policy or surety bond in a due and timely manner,
(B) has any disputes or claims against any underwriter of such insurance
policies or surety bonds or has failed to pay any premiums due and payable
thereunder, or (C) has failed to comply with all conditions contained in such
insurance policies and surety bonds. There are no facts or circumstances under
any such insurance policy or surety bond which would relieve any insurer of its
obligation to satisfy in full any valid claim of the Company or any Subsidiary.

              (j) There is no action, suit, proceeding, inquiry, arbitration,
investigation, litigation or governmental proceeding (including, without
limitation, those having jurisdiction over environmental or similar matters),
domestic or foreign, pending or threatened against (or circumstances that may
give rise to the same), or involving the properties or business of, the Company
or the Subsidiaries which (i) questions the validity of the capital stock of the
Company, this Agreement, the Warrant Agreement, the Affiliation Agreements (as
defined herein) or the Representative's Warrant Agreement, or of any action

having jurisdiction over any of the Company or the Subsidiaries or any of its or
their respective activities or properties.

              (l) No consent, approval, authorization or order of, and no filing

              (n) Subsequent to the respective dates as of which information is
set forth in the Registration Statement and Prospectus, and except as may
otherwise be indicated or contemplated herein or therein, none of the Company
nor the Subsidiaries has (i) issued any securities or incurred any liability or
obligation, direct or contingent, for borrowed money, (ii) entered into any
transaction other than in the ordinary course of business, or (iii) declared or
paid any dividend or made any other distribution on or in respect of its capital
stock of any class, and there has not been any change in the capital stock, or
any change in the debt (long or short term) or liabilities or material adverse
change in or affecting the general affairs, management, financial operations,
stockholders' equity or results of operations of any of the Company or the
Subsidiaries.

              (o) No default exists in the due performance and observance of any
term, covenant or condition of any license, contract, collective bargaining
agreement, indenture, mortgage, installment sale agreement, lease, deed of
trust, voting trust agreement, stockholders agreement, partnership agreement,
note, loan or credit agreement, purchase order, or any other agreement or
instrument evidencing an obligation for borrowed money, or any other material
agreement or instrument to which any of the Company or the Subsidiaries is a
party or by which any of the Company or the Subsidiaries may be bound or to
which the property or assets (tangible or intangible) of any of the Company or
the Subsidiaries is subject or affected.

              (p) Each of the Company and the Subsidiaries has generally enjoyed
a satisfactory employer-employee relationship with its employees and is in
compliance with all federal, state, local, and foreign laws and regulations
respecting employment and employment practices, terms and conditions of
employment and wages and hours. There are no pending investigations involving
any of the Company or the Subsidiaries by the U.S. Department of Labor, or any
other governmental agency responsible for the enforcement of such federal,
state, local, or foreign laws and regulations. There is no unfair labor practice
charge or complaint against any of the Company or the Subsidiaries pending
before the National Labor Relations Board or any lockout, strike, picketing,
boycott, dispute, slowdown or stoppage pending or threatened against or
involving any of the Company or the Subsidiaries, or any predecessor entity, and
none has ever occurred. No representation question exists respecting the
employees of any of the Company or the Subsidiaries, and no collective
bargaining agreement or modification thereof is currently being negotiated by
any of the Company or the Subsidiaries. No grievance or arbitration proceeding
is pending under any expired or existing collective bargaining agreements of any
of the Company or the Subsidiaries. No labor dispute with the employees of any
of the Company or the Subsidiaries exists, or, is imminent.

              (q) None of the Company nor any of the Subsidiaries maintains,
sponsors or contributes to any program or arrangement that is an "employee
pension benefit plan," an "employee welfare benefit plan," or a "multiemployer
plan" as such terms are defined in Sections 3(2), 3(1) and 3(37), respectively,
of the Employee Retirement Income Security Act of 1974, as amended ("ERISA")
("ERISA Plans"). None of the Company nor the Subsidiaries maintains or
contributes, now or at any time previously, to a defined benefit plan, as
defined in Section 3(35) of ERISA. No ERISA Plan (or any trust created
thereunder) has engaged in a "prohibited transaction" within the meaning of
Section 406 of ERISA or Section 4975 of the Code, which could subject the
Company or the Subsidiaries to any tax penalty on prohibited transactions and
which has not adequately been corrected. Each ERISA Plan is in compliance with
all reporting, disclosure and


                                       8
<PAGE>


other requirements of the Code and ERISA as they relate to any such ERISA Plan.
Determination letters have been received from the Internal Revenue Service with
respect to each ERISA Plan which is intended to comply with Code Section 401(a),
stating that such ERISA Plan and the attendant trust are qualified thereunder.
None of the Company nor the Subsidiaries has ever completely or partially
withdrawn from a "multiemployer plan."

              (r) None of the Company, the Subsidiaries, nor any of its or their
respective employees, directors, stockholders, partners, or affiliates (within
the meaning of the Rules and Regulations) of any of the foregoing has taken or
will take, directly or indirectly, any action designed to or which has
constituted or which might be expected to cause or result in, under the Exchange
Act, or otherwise, stabilization or manipulation of the price of any security of
the Company to facilitate the sale or resale of the Securities or otherwise.

              (s) Each of the Company and the Subsidiaries has good and
marketable title to, or valid and enforceable leasehold estates in, all items of
real and personal property stated in the Prospectus to be owned or leased by it,
free and clear of all liens, charges, claims, encumbrances, pledges, security
interests, defects, or other restrictions or equities of any kind whatsoever,
other than those referred to in the Prospectus and liens for taxes not yet due
and payable.

              (t) Ernst & Young, LLP, whose report is filed with the Commission
as a part of the Registration Statement, are independent certified public
accountants as required by the Act and the Rules and Regulations.

              (u) The Company has caused to be duly executed legally binding and
enforceable agreements pursuant to which each of the Company's officers,
directors, stockholders and holders of securities exchangeable or exercisable
for or convertible into shares of Common Stock has agreed (i) not to, directly
or indirectly, issue, offer, offer to sell, sell, grant any option for the sale
or purchase of, assign, transfer, pledge, hypothecate or otherwise encumber or
dispose of any shares of Common Stock or securities convertible into,
exercisable or exchangeable for or evidencing any right to purchase or subscribe
for any shares of Common Stock (either pursuant to Rule 144 of the Rules and
Regulations or otherwise) or dispose of any beneficial interest therein for a
period of not less than twenty-four (24) months following the effective date of
the Registration Statement without the prior written consent of the
Representative and the Company and (ii) to waive all rights to request or demand
the registration pursuant to the Act of any securities of the Company which are
registered in the name of or beneficially owned by any such holder. During the
24 month period commencing on the effective date of the Registration Statement,
the Company shall not, without the prior written consent of the Representative,
sell, contract or offer to sell, issue, transfer, assign, pledge, distribute, or
otherwise dispose of, directly or indirectly, any shares of Common Stock or any
options, rights or warrants with respect to any shares of Common Stock. The
Company will cause the Transfer Agent (as hereinafter defined) to mark an
appropriate legend on the face of stock certificates representing all of such
securities and to place "stop transfer" orders on the Company's stock ledgers.

              (v) There are no claims, payments, issuances, arrangements or
understandings, whether oral or written, for services in the nature of a
finder's or origination fee with respect to the sale of the Securities hereunder
or any other arrangements, agreements, understandings, payments or


                                       9

issuance with respect to the Company, the Subsidiaries, or any of its or their
respective officers, directors, stockholders, partners, employees or affiliates,
that may affect the Underwriters' compensation, as determined by the National
Association of Securities Dealers, Inc. ("NASD").

              (w) The Common Stock has been approved for quotation on the Nasdaq
Small Cap Market ("Nasdaq").

              (x) None of the Company, the Subsidiaries, nor any of its or their
respective officers, employees, agents or any other person acting on behalf of
any of the Company or the Subsidiaries has, directly or indirectly, given or
agreed to give any money, gift or similar benefit (other than legal price
concessions to customers in the ordinary course of business) to any customer,
supplier, employee or agent of a customer or supplier, or official or employee
of any governmental agency (domestic or foreign) or instrumentality of any
government (domestic or foreign) or any political party or candidate for office
(domestic or foreign) or other person who was, is, or may be in a position to
help or hinder the business of any of the Company or the Subsidiaries (or assist
any of the Company or the Subsidiaries in connection with any actual or proposed
transaction) which (a) might subject any of the Company or the Subsidiaries, or
any other such person to any damage or penalty in any civil, criminal or
governmental litigation or proceeding (domestic or foreign), (b) if not given in
the past, might have had a material adverse effect on the assets, business or
operations of any of the Company or the Subsidiaries, or (c) if not continued in
the future, might adversely affect the assets, business, condition, financial or
otherwise, earnings, position, properties, value, operations or prospects of any
of the Company or the Subsidiaries. The Company's and each Subsidiary's internal
accounting controls are sufficient to cause each of the Company and the
Subsidiaries to comply with the Foreign Corrupt Practices Act of 1977, as
amended.

              (y) Except as set forth in the Prospectus, no officer, director,
stockholder or partner of the Company or of any Subsidiary, or any "affiliate"
or "associate" (as these terms are defined in Rule 405 promulgated under the
Rules and Regulations) of any of the foregoing persons or entities has or has
had, either directly or indirectly, (i) an interest in any person or entity
which (A) furnishes or sells services or products which are furnished or sold or
are proposed to be furnished or sold by any of the Company or the Subsidiaries,
or (B) purchases from or sells or furnishes to any of the Company or the
Subsidiaries any goods or services, or (ii) a beneficiary interest in any
contract or agreement to which the Company or any Subsidiary is a party or by
which it may be bound or affected. Except as set forth in the Prospectus under
"Certain Transactions," there are no existing agreements, arrangements,
understandings or transactions, or proposed agreements, arrangements,
understandings or transactions, between or among the Company or any Subsidiary,
and any officer, director, or 5% or greater securityholder of the Company or any
Subsidiary, or any partner, affiliate or associate of any of the foregoing
persons or entities.

              (z) Any certificate signed by any officer of the Company or any
Subsidiary, and delivered to the Underwriters or to Underwriters' Counsel (as
defined herein) shall be deemed a representation and warranty by the Company to
the Underwriters as to the matters covered thereby.

              (aa) The minute books of each of the Company and the Corporate
Practices have been made available to the Underwriters and contain a complete
summary of all meetings and actions of the directors (including committees
thereof) and stockholders of each of the Company and the Corporate Practices,
since the time of its incorporation, and reflect all transactions referred to in
such minutes accurately in all material respects.

              (ab) Except and to the extent described in the Prospectus, no
holders of any securities of the Company or of any options, warrants or other
convertible or exchangeable securities of the Company have the right to include
any securities issued by the Company in the Registration Statement or any
registration statement to be filed by the Company or to require the Company to
file a registration statement under the Act and no person or entity holds any
anti-dilution rights with respect to any securities of the Company.

              (ac) The Company has as of the effective date of the Registration

Schulhof and Dr. Dean C. Bellavia in the form filed as Exhibit ______ and

date hereof that it is in compliance with all provisions of Section 1 of Laws of
Florida, Chapter 92-198, An Act Relating to Disclosure of Doing Business with
Cuba, and each of the Company and the Subsidiaries further agrees that if it or
any affiliate commences engaging in business with the government of Cuba or with
any person or affiliate located in Cuba after the date the Registration
Statement becomes or has become effective with the Commission or with the
Florida Department of Banking and Finance (the "Department"), whichever date is
later, or if the information reported or incorporated by reference in the
Prospectus, if any, concerning the Company's, any Subsidiary's or any
affiliate's, business with Cuba or with any person or affiliate located in Cuba
changes in any material way, the Company will provide the Department notice of
such business or change, as appropriate, in a form acceptable to the Department.

              (ae) The Company is not, and upon the issuance and sale of the
Securities as herein contemplated and the application of the net proceeds
therefrom as described in the Prospectus under the caption "Use of Proceeds"
will not be, an "investment company" or an entity "controlled" by an "investment
company" as such terms are defined in the Investment Company Act of 1940, as
amended (the "1940 Act").

              (af) Each of the Company and the Subsidiaries maintain a system of
internal accounting controls sufficient to provide reasonable assurance that (i)
transactions are executed in accordance with management's general or specific
authorizations; (ii) transactions are recorded as necessary to permit
preparations of financial statements in conformity with generally accepted
accounting principles and to maintain accountability for assets; (iii) access to
assets is permitted only in accordance with management's general or specific
authorizations; and (iv) the recorded accountability for assets is compared with
the existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

              (ag) The Company has entered into a warrant agreement
substantially in the form filed as Exhibit ____ to the Registration Statement

              (ah) Prior to the date hereof, the Company has entered into
Affiliation Agreements with each of the Subsidiaries in the form filed as
Exhibit __ to the Registration Statement (the "Affiliation Agreements"). Each of
the Affiliation Agreements has been duly and validly authorized, executed and

set forth in Schedule A opposite the name of such Underwriter, subject to such
adjustment as the Representative in its sole discretion shall make to eliminate
any sales or purchases of fractional shares, plus any additional number of Firm
Securities which such Underwriter may become obligated to purchase pursuant to
the provisions of Section 11 hereof.

              (b) In addition, on the basis of the representations, warranties,
covenants and agreements herein contained, but subject to the terms and
conditions herein set forth, the Company hereby grants an option to the
Underwriters, severally and not jointly, to purchase all or any part of an
additional 270,000 shares of Common Stock at a price of $ ____ [90% of the
public offering price] per share of Common Stock and/or an additional 270,000
Redeemable Warrants at a price of $______ [90% of the public offering price] per

after (i) the date the Registration Statement becomes effective, if the Company
has elected not to rely on Rule 430A under the Rules and Regulations, or (ii)
the date of this Agreement if the Company has elected to rely upon Rule 430A

in connection with the offering and distribution of the Firm Securities upon
notice by the Representative to the Company setting forth the number of Option
Securities as to which the several Underwriters are then exercising the 


                                       12
<PAGE>


option and the time and date of payment and delivery for any such Option
Securities. Any such time and date of delivery (an "Option Closing Date") shall
be determined by the Representative, but shall not be later than three (3) full
business days after the exercise of said option, nor in any event prior to the
Closing Date, as hereinafter defined, unless otherwise agreed upon by the
Representative and the Company. Nothing herein contained shall obligate the
Underwriters to make any over-allotments. No Option Securities shall be
delivered unless the Firm Securities shall be simultaneously delivered or shall
theretofore have been delivered as herein provided.

              (c) Payment of the purchase price for, and delivery of
certificates for, the Firm Securities shall be made at the offices of the
Representative at 1001 Fourth Avenue, Suite 2200, Seattle, Washington 98154, or
at such other place as shall be agreed upon by the Representative and the

of certificates for, such Option Securities shall be made at the above-mentioned
office of the Representative or at such other place as shall be agreed upon by
the Representative and the Company on each Option Closing Date as specified in
the notice from the Representative to the Company. Delivery of the certificates
for the Firm Securities and the Option Securities, if any, shall be made to the
Underwriters against payment by the Underwriters, severally and not jointly, of
the purchase price for the Firm Securities and the Option Securities, if any, to
the order of the Company for the Firm Securities and the Option Securities, if
any, by New York Clearing House funds. In the event such option is exercised,
each of the Underwriters, acting severally and not jointly, shall purchase that
proportion of the total number of Option Securities then being purchased which
the number of Firm Securities set forth in Schedule A hereto opposite the name
of such Underwriter bears to the total number of Firm Securities, subject in
each case to such adjustments as the Representative in its discretion shall make
to eliminate any sales or purchases of fractional shares. Certificates for the
Firm Securities and the Option Securities, if any, shall be in definitive, fully
registered form, shall bear no restrictive legends and shall be in such
denominations and registered in such names as the Underwriters may request in
writing at least two (2) business days prior to the Closing Date or the relevant
Option Closing Date, as the case may be. The certificates for the Firm
Securities and the Option Securities, if any, shall be made available to the
Representative at such office or such other place as the Representative may
designate for inspection, checking and packaging no later than 9:30 a.m. on the
last business day prior to the Closing Date or the relevant Option Closing Date,
as the case may be.

              (d) On the Closing Date, the Company shall issue and sell to the
Representative Representative's Warrants at a purchase price of $.0001 per
warrant, which Representative's Warrants shall entitle the holders thereof to
purchase an aggregate of 180,000 shares of Common Stock and/or 180,000
Redeemable Warrants. The Representative's Warrants shall be exercisable for a
period of four (4) years commencing one (1) year from the effective date of the
Registration Statement at a price equaling one hundred twenty percent (120%) of
the respective initial public offering price of the Shares and the Redeemable
Warrants. The Representative's Warrant Agreement and form of Warrant Certificate
shall be substantially in the form filed as Exhibit [___] 


                                       13

be made on the Closing Date.

        3. Public Offering of the Shares and Redeemable Warrants. As soon after

Redeemable Warrants (other than to residents of or in any jurisdiction in which
qualification of the Shares and Redeemable Warrants is required and has not
become effective) at the price and upon the other terms set forth in the
Prospectus. The Representative may from time to time increase or decrease the
respective public offering price after distribution of the Shares and Redeemable
Warrants has been completed to such extent as the Representative, in its sole
discretion deems advisable. The Underwriters may enter into one of more
agreements as the Underwriters, in each of their sole discretion, deem advisable
with one or more broker-dealers who shall act as dealers in connection with such
public offering.

        4. Covenants and Agreements of the Company. The Company covenants and
agrees with each of the Underwriters as follows:

              (a) The Company shall use its best efforts to cause the
Registration Statement and any amendments thereto to become effective as

Registration Statement or supplement to the Prospectus or file any document
under the Act or Exchange Act before termination of the offering of the Shares
and Redeemable Warrants by the Underwriters of which the Representative shall
not previously have been advised and furnished with a copy, or to which the
Representative shall have objected or which is not in compliance with the Act,
the Exchange Act or the Rules and Regulations.

              (b) As soon as the Company is advised or obtains knowledge
thereof, the Company will advise the Representative and confirm the notice in
writing (i) when the Registration Statement, as amended, becomes effective, if
the provisions of Rule 430A promulgated under the Act will be relied upon, when
the Prospectus has been filed in accordance with said Rule 430A and when any
post-effective amendment to the Registration Statement becomes effective; (ii)
of the issuance by the Commission of any stop order or of the initiation, or the
threatening, of any proceeding suspending the effectiveness of the Registration
Statement or any order preventing or suspending the use of the Preliminary

institution of proceedings for that purpose; (iii) of the issuance by the
Commission or by any state securities commission of any proceedings for the
suspension of the qualification of any of the Securities for offering or sale in
any jurisdiction or of the initiation, or the threatening, of any proceeding for
that purpose; (iv) of the receipt of any comments from the Commission; and (v)
of any request by the Commission for any amendment to the Registration Statement
or any amendment or supplement to the Prospectus or for additional information.
If the Commission or any state securities commission shall enter a stop order or
suspend such qualification at any time, the Company will make every effort to
obtain promptly the lifting of such order.

              (c) The Company shall file the Prospectus (in form and substance
satisfactory to the Representative) or transmit the Prospectus by a means

Prospectus (including any revised prospectus which the Company proposes for use
by the Underwriters in connection with the offering of the Securities which
differs from the corresponding prospectus on file at the Commission at the time
the Registration Statement becomes effective, whether or not such revised
prospectus is required to be filed pursuant to Rule 424(b) of the Rules and
Regulations), and will furnish the Representative with copies of any such
amendment or supplement a reasonable amount of time prior to such proposed
filing or use, as the case may be, and will not file any such prospectus to
which the Representative or Orrick, Herrington & Sutcliffe LLP ("Underwriters'
Counsel") shall object.

              (e) The Company shall endeavor in good faith, in cooperation with
the Representative, at or prior to the time the Registration Statement becomes
effective, to qualify the Securities for offering and sale under the securities
laws of such jurisdictions as the Representative may designate to permit the
continuance of sales and dealings therein for as long as may be necessary to
complete the distribution, and shall make such applications, file such documents
and furnish such information as may be required for such purpose; provided,
however, the Company shall not be required to qualify as a foreign corporation
or file a general or limited consent to service of process in any such
jurisdiction. In each jurisdiction where such qualification shall be effected,
the Company will, unless the Representative agrees that such action is not at
the time necessary or advisable, use all reasonable efforts to file and make
such statements or reports at such times as are or may reasonably be required by
the laws of such jurisdiction to continue such qualification.

              (f) During the time when a prospectus is required to be delivered
under the Act, the Company shall use all reasonable efforts to comply with all
requirements imposed upon it by the Act and the Exchange Act, as now and
hereafter amended and by the Rules and Regulations, as from time to time in
force, so far as necessary to permit the continuance of sales of or dealings in
the Securities in accordance with the provisions hereof and the Prospectus, or
any amendments or supplements thereto. If at any time when a prospectus relating
to the Securities is required to be delivered under the Act, any event shall
have occurred as a result of which, in the opinion of counsel for the Company or
Underwriters' Counsel, the Prospectus, as then amended or supplemented, includes
an untrue statement of a material fact or omits to state any material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading, or if
it is necessary at any time to amend the Prospectus to comply with the Act, the
Company will notify the Representative promptly and prepare and file with the
Commission an appropriate amendment or supplement in accordance with Section 10
of the Act, each such amendment or supplement to be satisfactory to
Underwriters' Counsel, and the Company will furnish to the Underwriters copies
of such amendment or supplement as soon as available and in such quantities as
the Underwriters may request.

              (g) As soon as practicable, but in any event not later than
forty-five (45) days after the end of the 12-month period beginning on the day
after the end of the fiscal quarter of the Company during which the effective
date of the Registration Statement occurs (ninety (90) days in the event that
the end of such fiscal quarter is the end of the Company's fiscal year), the
Company shall make generally available to its security holders, in the manner
specified in Rule 158(b) of the Rules and Regulations, and to the
Representative, an earnings statement which will be in the detail required by,
and will otherwise comply with, the provisions of Section 11(a) of the Act and
Rule 158(a) of the Rules and Regulations, which statement need not be audited
unless required by the Act, covering a period of at least twelve (12)
consecutive months after the effective date of the Registration Statement.

              (h) During a period of seven (7) years after the date hereof, the
Company will furnish to its stockholders, as soon as practicable, annual reports
(including financial statements audited by independent public accountants) and
unaudited quarterly reports of earnings, and will deliver to the Representative:

              i. concurrently with furnishing such quarterly reports to its
       stockholders, statements of income of the Company for each quarter in the
       form furnished to the Company's stockholders and certified by the
       Company's principal financial or accounting officer;

              ii. concurrently with furnishing such annual reports to its
       stockholders, a balance sheet of the Company as at the end of the
       preceding fiscal year, together with statements of operations,
       stockholders' equity, and cash flows of the Company for such fiscal year,
       accompanied by a copy of the certificate thereon of independent certified
       public accountants;

              iii. as soon as they are available, copies of all reports
       (financial or other) mailed to stockholders;

              iv. as soon as they are available, copies of all reports and
       financial statements furnished to or filed with the Commission, the NASD
       or any securities exchange;

              v. every press release and every material news item or article of
       interest to the financial community in respect of the Company, or its
       affairs, which was released or prepared by or on behalf of the Company;
       and

              vi. any additional information of a public nature concerning the
       Company (and any future subsidiary) or its businesses which the
       Representative may request.

        During such seven-year period, if the Company has an active subsidiary,
the foregoing financial statements will be on a consolidated basis to the extent
that the accounts of the Company and its subsidiary(ies) are consolidated, and
will be accompanied by similar financial statements for any significant
subsidiary which is not so consolidated.

              (i) The Company will maintain a transfer agent and warrant agent
("Transfer Agent") and, if necessary under the jurisdiction of incorporation of
the Company, a Registrar (which may be the same entity as the Transfer Agent)
for its Common Stock and Redeemable Warrants.

be signed and will include all financial statements and exhibits), the
Prospectus, and all amendments and supplements thereto, including any prospectus
prepared after the effective date of the Registration Statement, in each case as
soon as available and in such quantities as the Representative may request.

              (k) On or before the effective date of the Registration Statement,
the Company shall provide the Representative with true original copies of duly
executed, legally binding and enforceable agreements pursuant to which, for a
period of twenty-four (24) months from the effective date of the Registration
Statement, each of the Company's stockholders and holders of securities
exchangeable or exercisable for or convertible into shares of Common Stock
agrees that it or he or she (i) will not, directly or indirectly, issue, offer
to sell, sell, grant an option for the sale or purchase of, assign, transfer,
pledge, hypothecate or otherwise encumber or dispose of any shares of Common
Stock or securities convertible into, exercisable or exchangeable for or
evidencing any right to purchase or subscribe for any shares of Common Stock
(either pursuant to Rule 144 of the Rules and Regulations or otherwise) or
dispose of any beneficial interest therein without the prior consent of the
Representative (collectively, the "Lock-up Agreements") and (ii) waives, during
such 24 month period, any and all rights to request or demand the registration
pursuant to the Act, of any securities of the Company which are registered in
the name of or beneficially owned by it or he or she, respectively. During the
24 month period commencing on the effective date of the Registration Statement,
the Company shall not, without the prior written consent of the Representative,
sell, contract or offer to sell, issue, transfer, assign, pledge, distribute, or
otherwise dispose of, directly or indirectly, any shares of Common Stock or any
options, rights or warrants with respect to any shares of Common Stock. On or
before the Closing Date, the Company shall deliver instructions to the Transfer
Agent authorizing it to place appropriate legends on the certificates
representing the securities subject to the Lock-up Agreements and to place
appropriate stop transfer orders on the Company's ledgers.

              (l) None of the Company, the Subsidiaries, nor any of its or their
respective officers, directors, stockholders, nor any of its or their respective
affiliates (within the meaning of the Rules and Regulations) will take, directly
or indirectly, any action designed to, or which might in the future reasonably
be expected to cause or result in, stabilization or manipulation of the price of
any securities of the Company.

              (m) The Company shall apply the net proceeds from the sale of the
Securities in the manner, and subject to the conditions, set forth under "Use of
Proceeds" in the Prospectus. No portion of the net proceeds will be used,
directly or indirectly, to acquire any securities issued by the Company.

              (n) The Company shall timely file all such reports, forms or other
documents as may be required (including, but not limited to, a Form SR as may be
required pursuant to Rule 463 under the Act) from time to time, under the Act,
the Exchange Act, and the Rules and Regulations, and all such reports, forms and
documents filed will comply as to form and substance with the applicable
requirements under the Act, the Exchange Act, and the Rules and Regulations.

              (r) As soon as practicable, (i) but in no event more than five (5)
business days before the effective date of the Registration Statement, file a
Form 8-A with the Commission providing for the registration under the Exchange
Act of the Securities and (ii) but in no event more than thirty (30) days after
the effective date of the Registration Statement, take all necessary and
appropriate actions to be included in Standard and Poor's Corporation
Descriptions and Moody's OTC Manual and to continue such inclusion for a period
of not less than seven (7) years.

              (s) The Company hereby agrees that it will not, for a period of
twelve (12) months from the effective date of the Registration Statement, adopt,
propose to adopt or otherwise permit to exist any employee, officer, director,
consultant or compensation plan or similar arrangement permitting (i) the grant,
issue, sale or entry into any agreement to grant, issue or sell any option,
warrant or other contract right (x) at an exercise price that is less than the

              (t) Until the completion of the distribution of the Securities,
the Company shall not, without the prior written consent of the Representative
and Underwriters' Counsel, issue, directly or indirectly, any press release or
other communication or hold any press conference with respect to the Company or
its activities or the offering contemplated hereby, other than trade releases


                                       18
<PAGE>


issued in the ordinary course of the Company's business consistent with past
practices with respect to the Company's operations.

              (u) For a period equal to the lesser of (i) seven (7) years from
the date hereof, and (ii) the sale to the public of the Representative's
Securities, the Company will not take any action or actions which may prevent or
disqualify the Company's use of Form SB-2 (or other appropriate form) for the
registration under the Act of the Representative's Securities. The Company
further agrees to use its best efforts to file such post-effective amendments to
the Registration Statement, as may be necessary, in order to maintain its
effectiveness and to keep such Registration Statement effective while any of the
Redeemable Warrants or Representative's Warrants remain outstanding.

              (v) Commencing one year and one day from the date hereof, if the
Company engages the Representative as a warrant solicitation agent under the
terms of the Warrant Agreement, the Company shall pay the Representative a
commission equal to five percent (5%) of the exercise price of the Redeemable

the Warrant Agreement; provided, however, the Representative shall be entitled
to receive the commission contemplated by this Section 4(v) only if: (i) the
Representative has provided actual services in connection with the solicitation
of the exercise of a Redeemable Warrant by a Warrantholder and (ii) the
Warrantholder exercising a Redeemable Warrant affirmatively designates in
writing on the exercise form on the reverse side of the Redeemable Warrant
Certificate that the exercise of such Warrantholder's Redeemable Warrant was
solicited by the Representative.

              (w) For a period of one (1) year after the effective date of the
Registration Statement, the Company shall cause one (1) individual selected by
the Representative to be elected to the board of directors of the Company, if
requested by the Representative. In the event that the Representative shall not
have designated such individual at the time of any meeting of the Company's
board of directors or in the event that such individual has not been elected or
is unavailable to serve, the Company shall notify the Representative of each
meeting of its board of directors and, in such event, an individual selected by
the Representative shall be permitted to attend all meetings of the Company's
board of directors as a non-voting advisor and to receive all notices and other
correspondence and communications sent by the Company to the members of its
board of directors. Such board member or non-voting advisor shall receive no
more or less compensation than is paid to other non-officer directors of the
Company for attendance at meetings of the Company's board of directors and such
board member or non-voting advisor shall be entitled to receive reimbursement
for all reasonable costs incurred in attending such meetings, including, but not
limited to, food, lodging and transportation. The Company hereby agrees to
indemnify and hold such director or non-voting advisor harmless, to the maximum
extent permitted by law, against any and all actions, suits, proceedings,
inquiries, arbitrations, investigations, litigation, governmental or other
proceedings, domestic or foreign, and awards and judgments arising out of such
individual's service as a director or non-voting advisor and, in the event that
the Company maintains a liability insurance policy affording coverage for the
acts of its officers and directors, and/or in the event that the Company has
entered into an indemnification agreement with any of its officers or directors,
the Company agrees to include such director or non-voting advisor as an insured
under such insurance policy and/or to enter into an indemnification agreement
with such director or non-voting advisor which is at least as favorable 


                                       19
<PAGE>


to such individual as any indemnification agreement that the Company has entered
into with any of its officers or directors. The rights and benefits of such
indemnification and the benefits of such insurance shall, to the maximum extent
possible, extend to the Representative insofar as it may be or may be alleged to
be responsible for such director or non-voting advisor. The Company agrees to
provide its outside directors with compensation as deemed appropriate and
customary for similar companies.

        5. Payment of Expenses.

              (a) The Company hereby agrees to pay on each of the Closing Date
and the Option Closing Date (to the extent not paid at the Closing Date) all

and disbursements of Underwriters' Counsel, less any amounts already paid

        6. Conditions of the Underwriters' Obligations. The obligations of the
Underwriters hereunder shall be subject to the continuing accuracy of the
representations and warranties of the Company herein as of the date hereof and
as of the Closing Date and each Option Closing Date, if any, as if they had been

issued and no proceedings for that purpose shall have been instituted or shall
be pending or contemplated by the Commission and any request on the part of the

transmitted to the Commission for filing pursuant to Rule 424(b) of the Rules
and Regulations within the prescribed time period and, prior to the Closing

accordance with the requirements of Rule 430A of the Rules and Regulations.

              (b) The Representative shall not have advised the Company that the
Registration Statement, or any amendment thereto, contains an untrue statement
of fact which, in the Representative's opinion, is material, or omits to state a
fact which, in the Representative's opinion, is material and is required to be
stated therein or is necessary to make the statements therein not misleading, or
that the Prospectus, or any supplement thereto, contains an untrue statement of
fact which, in the Representative's opinion, is material, or omits to state a
fact which, 


                                       21
<PAGE>


in the Representative's opinion, is material and is required to be stated
therein or is necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

              (c) On or prior to each of the Closing Date and each Option
Closing Date, if any, the Representative shall have received from Underwriters'
Counsel, such opinion or opinions with respect to the organization of the
Company, the validity of the Securities, the Registration Statement, the
Prospectus and other related matters as the Representative may request and
Underwriters' Counsel shall have received such papers and information as they
request to enable them to pass upon such matters.

              (d) At the Closing Date, the Underwriters shall have received the
favorable opinion of Robinson & Cole, counsel to the Company, dated the Closing
Date, addressed to the Underwriters and in form and substance satisfactory to
Underwriters' Counsel, to the effect that:

              i. each of the Company and the Corporate Practices (A) has been
       duly organized and is validly existing as a corporation in good standing
       under the laws of its jurisdiction, (B) is duly qualified and licensed
       and in good standing as a foreign corporation in each jurisdiction in
       which its ownership or leasing of any properties or the character of its
       operations requires such qualification or licensing, and (C) has all
       requisite corporate power and authority; each of the Company and the
       Subsidiaries has obtained any and all necessary authorizations,
       approvals, orders, licenses, certificates, franchises and permits of and
       from all governmental or regulatory officials and bodies (including,
       without limitation, those having jurisdiction over environmental or
       similar matters), to own or lease its properties and conduct its business
       as described in the Prospectus; each of the Company and the Subsidiaries
       is and has been doing business in compliance with all such
       authorizations, approvals, orders, licenses, certificates, franchises and
       permits and all federal, state and local laws, rules and regulations;
       and, none of the Company nor the Subsidiaries has received any notice of
       proceedings relating to the revocation or modification of any such
       authorization, approval, order, license, certificate, franchise, or
       permit which, singly or in the aggregate, if the subject of an
       unfavorable decision, ruling or finding, would materially adversely
       affect the business, operations, condition, financial or otherwise, or
       the earnings, business affairs, position, prospects, value, operation,
       properties, business or results of operations of the Company and the
       Subsidiaries taken as whole. The disclosures in the Registration
       Statement concerning the effects of federal, state and local laws, rules
       and regulations on each of the Company's and the Subsidiaries' businesses
       as currently conducted and as contemplated are correct in all material
       respects and do not omit to state a fact required to be stated therein or
       necessary to make the statements contained therein not misleading in
       light of the circumstances in which they were made.

              ii. except as described in the Prospectus, none of the Company nor
       the Subsidiaries owns an interest in any other corporation, partnership,
       joint venture, trust or other business entity;

              iii. the Company has a duly authorized, issued and outstanding
       capitalization as set forth in the Prospectus, and any amendment or
       supplement thereto, under 


                                       22
<PAGE>


       "CAPITALIZATION", and the Company is not a party to or bound by any
       instrument, agreement or other arrangement providing for it to issue,
       sell, transfer, purchase or redeem any capital stock, rights, warrants,
       options or other securities, except for this Agreement, the Warrant
       Agreement and the Representative's Warrant Agreement and as described in
       the Prospectus. The Securities and all other securities issued or
       issuable by the Company conform in all material respects to all
       statements with respect thereto contained in the Registration Statement
       and the Prospectus. All issued and outstanding securities of the Company
       have been duly authorized and validly issued and are fully paid and
       non-assessable; the holders thereof have no rights of rescission with
       respect thereto, and are not subject to personal liability by reason of
       being such holders; and none of such securities were issued in violation
       of the preemptive rights of any holders of any security of the Company or
       any similar rights granted by the Company. The Securities to be sold by
       the Company hereunder and under the Warrant Agreement and the
       Representative's Warrant Agreement are not and will not be subject to any
       preemptive or other similar rights of any stockholder, have been duly
       authorized and, when issued, paid for and delivered in accordance with
       the terms hereof, will be validly issued, fully paid and non-assessable
       and conform to the description thereof contained in the Prospectus; the
       holders thereof will not be subject to any liability solely as such
       holders; all corporate action required to be taken for the authorization,
       issue and sale of the Securities has been duly and validly taken; and the
       certificates representing the Securities are in due and proper form. The
       Representative's Warrants and the Redeemable Warrants constitute valid
       and binding obligations of the Company to issue and sell, upon exercise
       thereof and payment therefor, the number and type of securities of the
       Company called for thereby. Upon the issuance and delivery pursuant to
       this Agreement of the Firm Securities and the Option Securities and the
       Representative's Warrants to be sold by the Company, the Underwriters and

                                       30
<PAGE>


        Statement and Prospectus does not comply as to form in all material
        respects with the applicable accounting requirements of the Act and the
        Rules and Regulations or is not fairly presented in conformity with
        generally accepted accounting principles applied on a basis consistent
        with that of the audited financial statements of the Company and the
        Subsidiaries or the unaudited pro forma financial information included
        in the Registration Statement, (B) the unaudited financial statements
        and supporting schedules of the Company and the Subsidiaries included in
        the Registration Statement do not comply as to form in all material
        respects with the applicable accounting requirements of the Act and the
        Rules and Regulations or are not fairly presented in conformity with
        generally accepted accounting principles applied on a basis
        substantially consistent with that of the audited financial statements
        of the Company and the Subsidiaries included in the Registration
        Statement, or (C) at a specified date not more than five (5) days prior
        to the effective date of the Registration Statement, there has been any
        change in the capital stock or long-term debt of any of the Company or
        the Subsidiaries, or any decrease in the stockholders' equity or net
        current assets or net assets of any of the Company or the Subsidiaries
        as compared with amounts shown in the March 31, 1997 balance sheet
        included in the Registration Statement, other than as set forth in or
        contemplated by the Registration Statement, or, if there was any change
        or decrease, setting forth the amount of such change or decrease, and
        (D) during the period from March 31, 1997 to a specified date not more
        than five (5) days prior to the effective date of the Registration
        Statement, there was any decrease in net revenues, net earnings or
        increase in net earnings per common share of any of the Company or the
        Subsidiaries, in each case as compared with the corresponding period
        beginning March 31, 1996, other than as set forth in or contemplated by
        the Registration Statement, or, if there was any such decrease, setting
        forth the amount of such decrease;

              iv. setting forth, at a date not later than five (5) days prior to
        the date of the Registration Statement, the amount of liabilities of the
        Company and the Subsidiaries taken as a whole (including a break-down of
        commercial paper and notes payable to banks);

              v. stating that they have compared specific dollar amounts,
        numbers of shares, percentages of revenues and earnings, statements and
        other financial information pertaining to the Company and the
        Subsidiaries set forth in the Prospectus in each case to the extent that
        such amounts, numbers, percentages, statements and information may be
        derived from the general accounting records, including work sheets, of
        the Company and the Subsidiaries and excluding any questions requiring
        an interpretation by legal counsel, with the results obtained from the
        application of specified readings, inquiries and other appropriate
        procedures (which procedures do not constitute an examination in
        accordance with generally accepted auditing standards) set forth in the
        letter and found them to be in agreement;

              vi. statements as to such other matters incident to the
        transaction contemplated hereby as the Representative may request.

              (l) At the Closing Date and each Option Closing Date, if any, the
Underwriters shall have received from Ernst & Young, LLP a letter, dated as of
the Closing Date or the Option Closing Date, as the case may be, to the effect
that they reaffirm that statements made in the letter furnished pursuant to
subsection (k) of this Section, except that the specified date referred to shall


                                       31
<PAGE>


be a date not more than five (5) days prior to the Closing Date or the Option
Closing Date, as the case may be, and, if the Company has elected to rely on
Rule 430A of the Rules and Regulations, to the further effect that they have
carried out procedures as specified in clause (v) of subsection (k) of this
Section with respect to certain amounts, percentages and financial information
as specified by the Representative and deemed to be a part of the Registration
Statement pursuant to Rule 430A(b) and have found such amounts, percentages and
financial information to be in agreement with the records specified in such
clause (v).

              (m) On each of the Closing Date and each Option Closing Date, if
any, there shall have been duly tendered to the Representative for the several
Underwriters' accounts the appropriate number of Securities.

              (n) No order suspending the sale of the Securities in any
jurisdiction designated by the Representative pursuant to subsection (e) of
Section 4 hereof shall have been issued on either the Closing Date or the Option
Closing Date, if any, and no proceedings for that purpose shall have been
instituted or shall be contemplated.

              (o) On or before the Closing Date, the Company shall have executed
and delivered to the Representative, (i) the Representative's Warrant Agreement
substantially in the form filed as Exhibit [___] to the Registration Statement,
in final form and substance satisfactory to the Representative, and (ii) the
Representative's Warrants in such denominations and to such designees as shall
have been provided to the Company.

              (p) On or before the Closing Date, the Firm Securities and Option

and delivered to the Representative and the Transfer Agent the Warrant Agreement
substantially in the form filed as Exhibit [___] to the Registration Statement,
in final form and substance satisfactory to the Representative.

        If any condition to the Underwriters' obligations hereunder to be
fulfilled prior to or at the Closing Date or the relevant Option Closing Date,
as the case may be, is not so fulfilled, the Representative may terminate this
Agreement or, if the Representative so elects, it may waive any such conditions
which have not been fulfilled or extend the time for their fulfillment.

        7. Indemnification.

              (a) The Company agrees to indemnify and hold harmless each of the
Underwriters (for purposes of this Section 7 "Underwriter" shall include the
officers, directors, partners, employees, agents and counsel of the Underwriter,
including specifically each person who may be substituted for an Underwriter as
provided in Section 11 hereof), and each person, if any, who controls the


                                       32
<PAGE>


Underwriter ("controlling person") within the meaning of Section 15 of the Act
or Section 20(a) of the Exchange Act, from and against any and all losses,
claims, damages, expenses or liabilities, joint or several (and actions,
proceedings, investigations, inquiries, suits and litigation in respect
thereof), whatsoever (including but not limited to any and all expenses
whatsoever reasonably incurred in investigating, preparing or defending against
any such claim, action, proceeding, investigation, inquiry, suit or litigation,
commenced or threatened, or any claim whatsoever), as such are incurred, to
which the Underwriter or such controlling person may become subject under the
Act, the Exchange Act or any other statute or at common law or otherwise or
under the laws of foreign countries, arising out of or based upon (A) any untrue
statement or alleged untrue statement of a material fact contained (i) in any
Preliminary Prospectus, the Registration Statement or the Prospectus (as from
time to time amended and supplemented); (ii) in any post-effective amendment or
amendments or any new registration statement and prospectus in which is included
securities of the Company issued or issuable upon exercise of the Securities; or
(iii) in any application or other document or written communication (in this
Section 7 collectively called "application") executed by the Company or based
upon written information furnished by the Company in any jurisdiction in order
to qualify the Securities under the securities laws thereof or filed with the
Commission, any state securities commission or agency, Nasdaq or any other
securities exchange; (B) the omission or alleged omission therefrom of a
material fact required to be stated therein or necessary to make the statements
therein not misleading (in the case of the Prospectus, in the light of the
circumstances under which they were made), or (C) any breach of any
representation, warranty, covenant or agreement of the Company contained herein
or in any certificate by or on behalf of the Company or any of its officers
delivered pursuant hereto, unless, in the case of clause (A) or (B) above, such
statement or omission was made in reliance upon and in strict conformity with
written information furnished to the Company with respect to any Underwriter by
or on behalf of such Underwriter expressly for use in any Preliminary
Prospectus, the Registration Statement or Prospectus, or any amendment thereof
or supplement thereto, or in any application, as the case may be.

        The indemnity agreement in this subsection (a) shall be in addition to
any liability which the Company may have at common law or otherwise.

              (b) Each of the Underwriters agrees severally, but not jointly, to
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the Registration Statement, and each other person, if
any, who controls the Company within the meaning of the Act, to the same extent
as the foregoing indemnity from the Company to the Underwriters but only with
respect to statements or omissions, if any, made in any Preliminary Prospectus,
the Registration Statement or Prospectus or any amendment thereof or supplement
thereto or in any application made in reliance upon, and in strict conformity
with, written information furnished to the Company with respect to any
Underwriter by such Underwriter expressly for use in such Preliminary
Prospectus, the Registration Statement or Prospectus or any amendment thereof or
supplement thereto or in any such application, provided that such written
information or omissions only pertain to disclosures in the Preliminary
Prospectus, the Registration Statement or Prospectus directly relating to the
transactions effected by the Underwriters in connection with this Offering. The
Company acknowledges that the statements with respect to the public offering of
the Firm Securities and the Option Securities set forth under the heading
"Underwriting" and the stabilization legend in the Prospectus have been
furnished by the Underwriters expressly for use 


                                       33
<PAGE>


therein and constitute the only information furnished in writing by or on behalf
of the Underwriters for inclusion in the Prospectus.

              (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any claim, action, suit,
investigation, inquiry, proceeding or litigation, such indemnified party shall,
if a claim in respect thereof is to be made against one or more indemnifying
parties under this Section 7, notify each party against whom indemnification is
to be sought in writing of the commencement thereof (but the failure so to
notify an indemnifying party shall not relieve it from any liability which it
may have under this Section 7 except to the extent that it has been prejudiced
in any material respect by such failure or from any liability which it may have
otherwise). In case any such claim, action, suit, investigation, inquiry,
proceeding or litigation is brought against any indemnified party, and it
notifies an indemnifying party or parties of the commencement thereof, the
indemnifying party or parties will be entitled to participate therein, and to
the extent it may elect by written notice delivered to the indemnified party
promptly after receiving the aforesaid notice from such indemnified party, to
assume the defense thereof with counsel reasonably satisfactory to such
indemnified party. Notwithstanding the foregoing, the indemnified party or
parties shall have the right to employ its or their own counsel in any such case
but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties unless (i) the employment of such counsel shall
have been authorized in writing by the indemnifying parties in connection with
the defense of thereof at the expense of the indemnifying party, (ii) the
indemnifying parties shall not have employed counsel reasonably satisfactory to
such indemnified party to have charge of the defense thereof within a reasonable
time after notice of commencement thereof, or (iii) such indemnified party or
parties shall have reasonably concluded that there may be defenses available to
it or them which are different from or additional to those available to one or
all of the indemnifying parties (in which case the indemnifying parties shall
not have the right to direct the defense thereof on behalf of the indemnified
party or parties), in any of which events such fees and expenses of one
additional counsel shall be borne by the indemnifying parties. In no event shall
the indemnifying parties be liable for fees and expenses of more than one
counsel (in addition to any local counsel) separate from their own counsel for
all indemnified parties in connection with any one claim, action, suit,
investigation, inquiry, proceeding or litigation or separate but similar or
related claims, actions, suits, investigations, inquiries, proceedings or
litigation in the same jurisdiction arising out of the same general allegations
or circumstances. Anything in this Section 7 to the contrary notwithstanding, an
indemnifying party shall not be liable for any settlement of any claim, action,
suit, investigation, inquiry, proceeding or litigation effected without its
written consent; provided, however, that such consent was not unreasonably
withheld. An indemnifying party will not, without the prior written consent of
the indemnified parties, settle, compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit,
investigation, inquiry, proceeding or litigation in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim, action, suit,
investigation, inquiry, proceeding or litigation), unless such settlement,
compromise or consent (i) includes an unconditional release of each indemnified
party from all liability arising out of such claim, action, suit, investigation,
inquiry, proceeding or litigation and (ii) does not include a statement as to or
an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.


                                       34
<PAGE>


              (d) In order to provide for just and equitable contribution in any
case in which (i) an indemnified party makes claim for indemnification pursuant
to this Section 7, but it is judicially determined (by the entry of a final
judgment or decree by a court of competent jurisdiction and the expiration of
time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case notwithstanding the fact that
the express provisions of this Section 7 provide for indemnification in such
case, or (ii) contribution under the Act may be required on the part of any
indemnified party, then each indemnifying party shall contribute to the amount
paid as a result of such losses, claims, damages, expenses or liabilities (or
actions in respect thereof) (A) in such proportion as is appropriate to reflect
the relative benefits received by each of the contributing parties, on the one
hand, and the party to be indemnified on the other hand, from the offering of
the Firm Securities and the Option Securities or (B) if the allocation provided
by clause (A) above is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of each of the contributing parties, on the
one hand, and the party to be indemnified on the other hand in connection with
the statements or omissions that resulted in such losses, claims, damages,
expenses or liabilities, as well as any other relevant equitable considerations.
In any case where the Company is the contributing party and the Underwriters are
the indemnified party, the relative benefits received by the Company on the one
hand, and the Underwriters, on the other, shall be deemed to be in the same
proportion as the total net proceeds from the offering of the Firm Securities
and the Option Securities (before deducting expenses) bear to the total
underwriting discounts received by the Underwriters hereunder, in each case as
set forth in the table on the Cover Page of the Prospectus. Relative fault shall
be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company, or by the
Underwriters, and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such untrue statement or omission. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, expenses or liabilities (or actions in respect thereof)
referred to above in this subsection (d) shall be deemed to include any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (d), the Underwriters shall not be required to
contribute any amount in excess of the underwriting discount applicable to the
Firm Securities and the Option Securities purchased by the Underwriters
hereunder. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. For purposes of this
Section 7, each person, if any, who controls the Company or the Underwriter
within the meaning of the Act, each officer of the Company who has signed the
Registration Statement, and each director of the Company shall have the same
rights to contribution as the Company or the Underwriter, as the case may be,
subject in each case to this subsection (d). Any party entitled to contribution
will, promptly after receipt of notice of commencement of any action, suit or
proceeding against such party in respect to which a claim for contribution may
be made against another party or parties under this subsection (d), notify such
party or parties from whom contribution may be sought, but the omission so to
notify such party or parties shall not relieve the party or parties from whom
contribution may be sought from any obligation it or they may have hereunder or
otherwise than under this subsection (d), or to the extent that such party or
parties were not adversely affected by such omission. The 


                                       35
<PAGE>


contribution agreement set forth above shall be in addition to any liabilities
which any indemnifying party may have at common law or otherwise.

        8. Representations and Agreements to Survive Delivery. All
representations, warranties and agreements contained in this Agreement or
contained in certificates of officers of the Company submitted pursuant hereto,
shall be deemed to be representations, warranties and agreements at the Closing
Date and the Option Closing Date, as the case may be, and such representations,
warranties and agreements of the Company and the indemnity agreements contained
in Section 7 hereof, shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of any Underwriter, the
Company, any controlling person of any Underwriter or the Company, and shall
survive termination of this Agreement or the issuance and delivery of the
Securities to the Underwriters and the Representative, as the case may be.

        9. Effective Date. This Agreement shall become effective at 10:00 a.m.,
New York City time, on the next full business day following the date hereof, or
at such earlier time after the Registration Statement becomes effective as the
Representative, in its discretion, shall release the Securities for sale to the
public; provided, however, that the provisions of Sections 5, 7 and 10 of this
Agreement shall at all times be effective. For purposes of this Section 9, the
Securities to be purchased hereunder shall be deemed to have been so released
upon the earlier of dispatch by the Representative of telegrams to securities
dealers releasing such securities for offering or the release by the
Representative for publication of the first newspaper advertisement which is
subsequently published relating to the Securities.

        10. Termination.

              (a) Subject to subsection (b) of this Section 10, the
Representative shall have the right to terminate this Agreement, (i) if any
domestic or international event or act or occurrence has materially adversely
disrupted, or in the Representative's opinion will in the immediate future
materially adversely disrupt, the financial markets; or (ii) if any material
adverse change in the financial markets shall have occurred; or (iii) if trading
generally shall have been suspended or materially limited on or by, as the case
may be, any of the New York Stock Exchange, the American Stock Exchange, Nasdaq,
the NASD, the Boston Stock Exchange, the Commission or any governmental
authority having jurisdiction over such matters; or (iv) if trading of any of
the securities of the Company shall have been suspended, or any of the
securities of the Company shall have been delisted, on any exchange or in any
over-the-counter market; (v) if the United States shall have become involved in
a war or major hostilities, or if there shall have been an escalation in an
existing war or major hostilities or a national emergency shall have been
declared in the United States; or (vi) if a banking moratorium has been declared
by a state or federal authority; or (vii) if a moratorium in foreign exchange
trading has been declared; or (viii) if the Company shall have sustained a loss
material or substantial to the Company by fire, flood, accident, hurricane,
earthquake, theft, sabotage or other calamity or malicious act which, whether or
not such loss shall have been insured, will, in the Representative's opinion,
make it inadvisable to proceed with the offering, sale and/or delivery of the
Securities; or (ix) if there shall have been such a material adverse change in
the conditions or prospects of the Company, or such material adverse change in
the general market, political or economic conditions, in the United States or
elsewhere, that, in each case, in the Representative's judgment, would make it
inadvisable to 


                                       36
<PAGE>


proceed with the offering, sale and/or delivery of the Securities or (x) if
Robert Schulhof shall no longer serve the Company in his present capacity.

              (b) If this Agreement is terminated by the Representative in
accordance with the provisions of Section 10(a) the Company shall promptly
reimburse and indemnify the Representative for all of its actual out-of-pocket
expenses, including the fees and disbursements of counsel for the Underwriters
(less amounts previously paid pursuant to Section 5(c) above). Notwithstanding
any contrary provision contained in this Agreement, if this Agreement shall not
be carried out within the time specified herein, or any extension thereof
granted to the Representative, by reason of any failure on the part of the
Company to perform any undertaking or satisfy any condition of this Agreement by
it to be performed or satisfied (including, without limitation, pursuant to
Section 6 or Section 12) then, the Company shall promptly reimburse and
indemnify the Representative for all of its actual out-of-pocket expenses,
including the fees and disbursements of counsel for the Underwriters (less
amounts previously paid pursuant to Section 5(c) above). In addition, the
Company shall remain liable for all Blue Sky counsel fees and disbursements,
expenses and filing fees. Notwithstanding any contrary provision contained in
this Agreement, any election hereunder or any termination of this Agreement
(including, without limitation, pursuant to Sections 6, 10, 11 and 12 hereof),
and whether or not this Agreement is otherwise carried out, the provisions of
Section 5 and Section 7 shall not be in any way affected by such election or
termination or failure to carry out the terms of this Agreement or any part
hereof.

        11. Substitution of the Underwriters. If one or more of the Underwriters
shall fail (otherwise than for a reason sufficient to justify the termination of
this Agreement under the provisions of Section 6, Section 10 or Section 12
hereof) to purchase the Securities which it or they are obligated to purchase on
such date under this Agreement (the "Defaulted Securities"), the Representative
shall have the right, within 24 hours thereafter, to make arrangement for one or
more of the non-defaulting Underwriters, or any other underwriters, to purchase
all, but not less than all, of the Defaulted Securities in such amounts as may
be agreed upon and upon the terms herein set forth; if, however, the
Representative shall not have completed such arrangements within such 24-hour
period, then:

              (a) if the number of Defaulted Securities does not exceed 10% of
        the total number of Firm Securities to be purchased on such date, the
        non-defaulting Underwriters shall be obligated to purchase the full
        amount thereof in the proportions that their respective underwriting
        obligations hereunder bear to the underwriting obligations of all
        non-defaulting Underwriters, or

              (b) if the number of Defaulted Securities exceeds 10% of the total
        number of Firm Securities, this Agreement shall terminate without
        liability on the part of any non-defaulting Underwriters (or, if such
        default shall occur with respect to any Option Securities to be
        purchased on an Option Closing Date, the Underwriters may at the
        Representative's option, by notice from the Representative to the
        Company, terminate the Underwriters' obligation to purchase Option
        Securities from the Company on such date).


                                       37
<PAGE>


        No action taken pursuant to this Section 11 shall relieve any defaulting
Underwriter from liability in respect of any default by such Underwriter under
this Agreement.

        In the event of any such default which does not result in a termination
of this Agreement, the Representative shall have the right to postpone the
Closing Date for a period not exceeding seven (7) days in order to effect any
required changes in the Registration Statement or Prospectus or in any other
documents or arrangements.

        12. Default by the Company. If the Company shall fail at the Closing
Date or at any Option Closing Date, as applicable, to sell and deliver the
number of Securities which it is obligated to sell hereunder on such date, then
this Agreement shall terminate (or, if such default shall occur with respect to
any Option Securities to be purchased on an Option Closing Date, the
Underwriters may at the Representative's option, by notice from the
Representative to the Company, terminate the Underwriters' obligation to
purchase Option Securities from the Company on such date) without any liability
on the part of any non-defaulting party other than pursuant to Section 5,
Section 7 and Section 10 hereof. No action taken pursuant to this Section 12
shall relieve the Company from liability, if any, in respect of such default.

        13. Notices. All notices and communications hereunder, except as herein
otherwise specifically provided, shall be in writing and shall be deemed to have
been duly given if mailed or transmitted by any standard form of
telecommunication. Notices to the Underwriters shall be directed to the

        14. Parties. This Agreement shall inure solely to the benefit of and
shall be binding upon, the Underwriters, the Company and the controlling
persons, directors and officers referred to in Section 7 hereof, and their
respective successors, legal representatives and assigns, and no other person
shall have or be construed to have any legal or equitable right, remedy or claim
under or in respect of or by virtue of this Agreement or any provisions herein
contained. No purchaser of Securities from any Underwriter shall be deemed to be
a successor by reason merely of such purchase.

        15. Construction. This Agreement shall be governed by and construed and
enforced in accordance with the laws of the State of New York without giving
effect to the choice of law or conflict of laws principles.

        16. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, and all of which
taken together shall be deemed to be one and the same instrument.

        17. Entire Agreement; Amendments. This Agreement, the Warrant Agreement
and the Representative's Warrant Agreement constitute the entire agreement of
the parties hereto and supersede all prior written or oral agreements,
understandings and negotiations with respect to the subject matter hereof. This
Agreement may not be amended except in a writing, signed by the Representative
and the Company.

        If the foregoing correctly sets forth the understanding between the
Underwriters and the Company, please so indicate in the space provided below for

     WHEREAS, subject to the foregoing, the Seller desires to sell and the Buyer
desires to purchase the Purchased Assets, in accordance with the terms,
conditions, and agreements hereinafter contained.

     NOW, THEREFORE, in consideration of the mutual premises and the covenants
and promises hereinafter contained, and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties
hereto, intending to be legally bound hereby, agree as follows:

     1.2 Excluded Assets. Any provisions of this Agreement to the contrary
notwithstanding, there shall be excluded from the purchase and sale contemplated

under the contracts, agreements and commitments of the Seller which are
specifically identified in Schedule 1.4 (the "Contracts") and are assigned to
the Buyer on the Effective Date, if and to the extent assignable, but only to
the extent any such obligations arise and accrue after the Effective Date and
then only in respect of events and time periods occurring after the Effective
Date (collectively, the "Assumed Obligations").

     1.5 Excluded Obligations. The Buyer is not assuming, and the Seller shall
remain fully responsible for, all past, present and future indebtedness,
liabilities, obligations, contracts and commitments of the Seller and any
predecessors in interest of the Business, known or unknown, fixed or contingent,

<PAGE>


hereof, the Buyer from and against, any and all such indebtedness, obligations
and liabilities.

"Shares") of the common stock, par value $.01 per share, of the Buyer (the
"Common Stock").

Section 3. Representations and Warranties.

     3.1 Seller. The Seller hereby represents and warrants to the Buyer, all of
which representations and warranties are true, complete, and correct in all
respects as of the date hereof, as follows:

     (a) Organization and Qualification. The Seller is a limited liability
company duly organized, validly existing and in good standing under the laws of
the state of California. The Seller has all requisite power and authority to own
those properties and conduct those businesses presently owned or conducted by
it. The copies of the Articles of Organization and the Operating Agreement of
the Seller, which have been delivered to the Buyer, are complete and correct and
are in full force and effect at the date hereof.

     (b) Authorization; No Restrictions, Consents or Approvals. The Seller has
full power and authority to enter into and perform this Agreement and the
Ancillary Agreements (as defined below) and all corporate and member action
necessary to authorize the execution and delivery of this Agreement and the
Ancillary Agreements and the performance hereunder and thereunder has been duly
taken. This Agreement and the Ancillary Agreements have been duly executed by
the Seller and constitute the legal, valid, binding and enforceable obligations
of the Seller, enforceable against the Seller in accordance with their terms.
The execution and delivery of this Agreement and the Ancillary Agreements, the
sale of the Purchased Assets and the consummation by the Seller of the
transactions contemplated herein and therein, do not (i) conflict with or
violate any of the terms of the Articles of Organization or the Operating
Agreement of the Seller or any applicable law, (ii) conflict with, or result in
a breach of any of the terms of any Contract or constitute a default thereunder,
(iii) result in the creation or imposition of any Lien on any of the Purchased
Assets, (iv) constitute an event permitting termination of any Contract pursuant
to the terms of such Contract, or (v) conflict with, or result in or constitute
a default under or breach or violation of or grounds for termination of, any
license, permit or other governmental authorization to which the Seller is a
party or by which the Seller may be bound, or result in the violation by the
Seller of any law, statute, rule, regulation, judgment, writ, injunction, decree
or order to which the Seller or any assets of the Seller may be subject, which
would materially adversely affect the transactions contemplated herein. No
authorization, consent or approval of, notice to, or filing with, any public
body or governmental authority or any other person is necessary in connection
with the execution and delivery by the Seller of this Agreement and the


                                       3
<PAGE>


Ancillary Agreements or the performance by the Seller of its obligations
hereunder or thereunder.

     (c) Title to Properties. The Seller has good and marketable title to all of
the Purchased Assets, free and clear of any Lien.

     (d) Contracts and Other Documents. Schedule 1.4 sets forth a complete and
accurate listing or description of all Contracts to which the Seller is a party
in connection with the Business. Each of the Contracts is valid, binding and
enforceable in accordance with its terms, and is in full force and effect; there
are no existing defaults on the part of the Seller or, to the best of the
Seller's knowledge, any other party, under any Contract, and no event of default
under any such Contract has occurred and is continuing which (whether with or
without the giving of notice, lapse of time or both, or the happening of any
other event) would constitute a default under such Contract; each such Contract
will continue to be in full force and effect on the same terms and conditions
immediately after the Effective Date without the need for any action on the part
of the Buyer, except for the Buyer's performance of the Assumed Obligations; to
the best of the Seller's knowledge, each such Contract reflects the complete
understanding among the parties thereto; and accurate and complete copies of
each such Contract including all amendments thereto, have been delivered to the
Buyer at or prior to the date hereof. The Seller's interest in each of the
Contracts is free and clear of all Liens or other encumbrances (other than any
created by the Buyer). Neither the Seller nor any other party is in default
under any Contract.

     (e) Compliance With Law. The Seller has at all times operated in all
respects and is presently in compliance with all applicable federal, state,
local, foreign or other laws, rules, regulations, guidelines, orders,
injunctions, building and other codes, ordinances, permits, licenses,
authorizations, judgments, decrees of federal, state, local, foreign or other
authorities, and all orders, writs, decrees and consents of any governmental or
political subdivision or agency thereof, or any court or similar person
established by any such governmental or political subdivision or agency thereof,
including but not limited to all applicable domestic and foreign laws, rules and
regulations relating to the safe conduct of business, employment discrimination,
wages and hours, employment of illegal aliens, collective bargaining, the
payment of withholding and social security taxes, product labeling, antitrust,
consumer protection, occupational safety and health, consumer product safety,
the importation of goods, product liability, currency exchange, securities and
trading with the enemy matters, and to the best of the Seller's knowledge no
event has occurred which would constitute reasonable grounds for a claim that
non-compliance has occurred or is occurring.

     (f) Intellectual Property. The Seller owns or possesses valid and binding
licenses or other rights to use, whether or not registered, all intellectual
property and intangible assets used or useful in the Business (the "Intellectual
Property"). Schedule 3.1(f) sets forth a complete and accurate list of all such
Intellectual Property (identifying those owned and those licensed), including
all United States, state and



                                       4
<PAGE>


foreign registrations or applications for registration thereof and all
agreements (including, without limitation, agreements pursuant to which the
Seller has granted licenses to third parties to use any Intellectual Property)
relating thereto. All actions necessary to maintain the registered Intellectual
Property have been taken by the Seller. The Seller is not required to pay any
royalty, license fee or similar compensation with respect to the Intellectual
Property in connection with the current or prior conduct of the Business. The
use by the Seller of any of the Intellectual Property does not violate the
proprietary rights of any other person and no claims have been asserted by any
person with respect to the use of the Intellectual Property by the Seller. To
the best of the Seller's knowledge, no person is infringing upon the
Intellectual Property. The Seller has taken reasonable security measures to
protect the secrecy, confidentiality and value of the Intellectual Property. No
person, other than the Seller, owns or has any proprietary, financial or other
interest, direct or indirect, in whole or in part, in any Intellectual Property.

     (g) Investment Representations. The Seller (i) was not organized for the
specific purpose of acquiring the Shares; (ii) has sufficient knowledge and
experience in investing in companies similar to the Buyer so as to be able to

financially to bear the risks thereof; (iii) has had a full and adequate
opportunity to discuss the Buyer's business, management and financial affairs
with the Buyer's management; (iv) is acquiring the Shares for its own account
for the purpose of investment and not with view to or for sale in connection

reason of the issuance of the Shares in a transaction exempt from the
registration requirements of the Act pursuant to Section 4(2) thereof or Rule
505 or 506 promulgated under the Act, (x) the Shares must be held indefinitely
unless a subsequent disposition thereof is registered under the Act or is exempt
from such registration, (y) the Shares will bear a legend to such effect and (z)
the Buyer will make a notation on its transfer books to such effect.

which representations and warranties are true, complete, and correct in all

corporation  formed under the laws of the State of Delaware (the "Buyer"),  does
hereby grant,  sell,  convey,  transfer,  assign and deliver to Buyer, and Buyer
does hereby  purchase from Seller all of Seller's  right,  title and interest in

     Specifically  excluded  from the  Purchased  Assets being sold and assigned
hereunder are the "Excluded Assets" which are all the assets of Seller which are
not described on Schedule 1.1.

     Anything herein to the contrary notwithstanding,  no Purchased Assets shall
be deemed  transferred or assigned  pursuant to this instrument if any attempted
transfer or  assignment  of the same  without the consent or approval of another
person or entity would in any way adversely affect the rights of Seller or Buyer
in the Purchased  Assets.  Seller covenants and agrees that in any such case the
beneficial  interest  in or to the  Purchased  Assets  shall in any  event  pass
hereunder as of the date hereof to Buyer; and Seller covenants and agrees to use
its best efforts to obtain and secure any and all such  consents  and  approvals
and take all actions  necessary to put Buyer in actual possession and control of
the Purchased Assets purchased by Buyer.

     Seller is lawfully  seized of all the Purchased  Assets and has clear title
to and good and lawful  authority to convey the Purchased  Assets to Buyer.  The

benefit of Seller and at the expense of Seller (i) to  institute  and  prosecute

enforce  any  claim,  right or title of any kind in or to the  Purchased  Assets

actions,  suits or proceedings in respect of any of the Purchased  Assets hereby
sold,  transferred  or  assigned  and  (iii) to take all such  further  acts and
actions in relation thereto as Buyer shall deem advisable.  Seller covenants and

delivery  hereof,  Seller  will,  upon the request of Buyer and at its  expense,
execute, acknowledge and deliver, or will cause to be executed, acknowledged and

of attorney or  assurances  and shall take or cause to be taken all such further

aiding and assisting in the  collection of or reducing to possession by Buyer of
any of the Purchased Assets hereby sold, transferred or assigned to Buyer.

     This  instrument  and the covenants and  agreements  herein set forth shall
inure to the  benefit  of Buyer  and its  successors  and  assigns  and shall be
binding upon Seller and its successors and assigns.

     Seller will warrant and defend the sale of Purchased Assets against all and
every person or persons  whomsoever  claiming or to claim  against any or all of
the same.

     This  instrument  shall be governed by and construed in accordance with the
laws of the State of  Delaware,  without  giving  effect to the  conflict of law
principles thereof.

     IN WITNESS WHEREOF, Seller, intending to be legally bound, has executed and
delivered, or caused to be duly executed and delivered on its behalf by its duly
authorized  representative,  this General Bill of Sale and  Assignment as of the
day and date first above set forth.

             AFFILIATION AGREEMENT AND AGREEMENT AND PLAN OF MERGER

     THIS AFFILIATION AGREEMENT AND AGREEMENT AND PLAN OF MERGER is entered into
as of the 10th day of March 1997, by and among Omega Orthodontics, Inc., a
Delaware corporation ("OMEGA"); Robert R. Schmisseur, D.D.S. ("Dr. Schmisseur"),
who is duly licensed to practice orthodontics in the state of Illinois (the
"State"); Robert R. Schmisseur, D.D.S., P.C., an Illinois professional
corporation (the "Orthodontic Entity"); and Omega Orthodontics of Champaign,
Inc., a Delaware corporation to be formed and to become a wholly owned
subsidiary of OMEGA ("Acquisition" and sometimes referred to herein as the
"Surviving Entity") (and which shall have joined herein by subsequently
executing this Agreement).

                                    RECITALS

     A. OMEGA provides professional management and marketing services to
orthodontic practices in the United States, which services include providing
practice management systems, office space, equipment, furnishings and active
administrative personnel necessary for the operation of orthodontic practices,
and which services are provided directly or indirectly through management
service organizations.

     B. The Orthodontic Entity owns and operates an orthodontic practice with
offices located at 1701 South Prospect, Champaign, Illinois 61820 (the
"Orthodontic Offices") and furnishes orthodontic care to the general public
through the services of Dr. Schmisseur affiliated with the Orthodontic Entity.

     C. Dr. Schmisseur presently holds 100% of the issued and outstanding
capital stock of the Orthodontic Entity (the issued and outstanding capital
stock is hereafter referred to herein as the "Interests").

     D. Dr. Schmisseur owns all of the Interests, and desires to convert the
status of the Orthodontic Entity from a professional entity to a general purpose
entity and to form a new professional corporation or entity to continue his
orthodontic practice at the Orthodontic Offices.

     E. OMEGA has conducted a review of the Orthodontic Entity, and has reviewed
the Orthodontic Entity's unaudited financial and operations statement provided
by Dr. Schmisseur (the "Financial Statement"), a copy of which is attached
hereto as Exhibit A . Based on its review of the Orthodontic Entity and the
Financial Statement, OMEGA has issued the report (the "Report"), a copy of which
has been furnished to the Orthodontic Entity. The Orthodontic Entity and Dr.
Schmisseur have reviewed the Report and OMEGA's literature, and agree with the
Report and the concepts of OMEGA's Exceptional Practice.

     F. Subject to the terms and conditions of this Agreement, OMEGA and Dr.
Schmisseur have determined that it is in the best interests of each to effect a
merger of the Orthodontic Entity with and into Acquisition (the "Merger") as
provided in Section 2.1 hereof.


<PAGE>

     NOW, THEREFORE, in consideration of the foregoing recitals and the mutual
promises contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged to the full
satisfaction of the parties hereto, the parties hereto agree as follows:


                   ARTICLE I. ENTITY FORMATION AND CONVERSION

     1.1 At the Closing (as defined in Section 2.3 hereof), Dr. Schmisseur shall
cause the Orthodontic Entity's charter ("Charter") to be amended to convert the
Orthodontic Entity into a general purpose entity under the laws of the State.

     1.2 Dr. Schmisseur shall form a new professional entity (the "New PC")
under the laws of the State and, in accordance with the terms of this Agreement,
commence the practice of orthodontics through the New PC.

     1.3 OMEGA shall form Acquisition and shall cause Acquisition to join in
this Agreement by subsequently executing this Agreement where indicated below.


                               ARTICLE II. MERGER

     2.1 Merger; Consideration and Payment.

     (a) At the Effective Time (as hereinafter defined) and subject to the terms
and conditions hereinafter set forth, the parties hereto agree to cause the
Merger to be consummated by filing with the Delaware Secretary of State and the
State Secretary of State (if required) a Certificate of Merger (the "Certificate
of Merger") in the form required by applicable law, duly executed and
acknowledged by the Surviving Entity, and taking all such further actions as may
be required by law to make the Merger effective. The Merger shall become
effective upon the filing of the Certificate of Merger with the Delaware
Secretary of State and the State Secretary of State (if required) (the
"Effective Time"), and Acquisition will be the surviving entity.

     (b) At the Effective Time, the Interests of Orthodontic Entity outstanding
immediately prior to the Effective Time shall, on such date, by virtue of the
Merger and upon surrender to OMEGA of the certificates therefor, duly endorsed
and transferable, free and clear of any liens, encumbrances, restrictions or
claims of any kind (other than those liens, encumbrances, restrictions and
claims expressly disclosed to OMEGA and affirmatively accepted by OMEGA prior to
the Effective Time), without any further action on the part of any holder
thereof, be converted into the right to receive an aggregate consideration (the
"Consideration") of:

               (ii) Two Hundred Eighteen Thousand, Forty Two Dollars
          ($218,042.00) to be represented by a promissory note (the "Purchase

          attached hereto as Exhibit B; and

               (iii) Two Hundred Eighteen Thousand, Forty Dollars ($218,040.00)

          of the IPO Price (as defined below in Section 2.3) (the "Stock
          Component"), which shall thereupon be issued to Dr. Schmisseur, fully
          paid and nonassessable.

     (c) At the Effective Time, each share of stock of Acquisition outstanding
immediately prior to the Effective Time shall, on such date, by virtue of the
Merger and without any action on the part of any holder thereof, continue and
shall be held by OMEGA.

     2.2 Adjustment and Audit.

     (a) The Consideration is based on the value of the Interests as determined
by OMEGA from the information set forth in the Financial Statement. At OMEGA's

to confirm the accuracy and completeness of the information in the Financial
Statement.

payroll taxes and related employment obligations; (iii) any accounts payable of
the Orthodontic Entity which have accrued prior to the Effective Time and which
remain unpaid as of such time (the "Accounts Payable") in excess of an amount
equal to one-half (1/2) of one "Average" month of gross income from the
Orthodontic Entity; (iv) and any other material adverse changes in the financial
condition or prospects of the Orthodontic Entity from the information provided
in the Financial Statement. As used herein, Average shall mean an average of the
Accounts Payable of the Orthodontic Entity using the last twelve months prior to
the end of the month immediately preceding the Effective Time.

     (c) The adjustments to the Consideration, if any, shall be applied in the
following order of priority; first to the Cash Component, second, to the Note
Component, and the balance, if any, to the Stock Component.

     2.3 Time and Place of Closing. The closing of the transactions contemplated
hereby (herein called the "Closing") shall be held immediately before the
Effective Time at the offices

                          ARTICLE IX. INDEMNIFICATION.

     9.1 Indemnification By Dr. Schmisseur. Subject to the limitations set forth
in Section 9.3, Dr. Schmisseur agrees to defend, indemnify and hold each of
OMEGA and Acquisition harmless from and against any damages, liabilities, losses
and expenses (including reasonable counsel fees) of any kind or nature
whatsoever which may be sustained or suffered by OMEGA or Acquisition based upon
a breach of any representation, warranty or covenant made by the Orthodontic
Entity or Dr. Schmisseur in this Agreement or in any exhibit, certificate,
schedule or financial statement delivered hereunder, or by reason of any claim,
action or proceeding asserted or instituted growing out of any matter or thing
covered by such representations, warranties or 




                                      -8-
<PAGE>

covenants. OMEGA and Acquisition may at their option recover such
indemnification claims by OMEGA or Acquisition by set-off against amounts of
principal and interest due under the Purchase Note, but shall not be required to
recover said claims in such manner and may proceed against Dr. Schmisseur and
his transferees in liquidation at any time or times for recovery of
indemnification claims.

     9.2 Indemnification By OMEGA and Acquisition. Subject to the limitations
set forth in Section 9.3, OMEGA and Acquisition, jointly and severally, each
agrees to defend, indemnify and hold Dr. Schmisseur harmless from and against
any damages, liabilities, losses and expenses (including reasonable counsel
fees) of any kind or nature whatsoever which may be sustained or suffered by Dr.
Schmisseur based upon a breach of any representation, warranty or covenant made
by OMEGA or Acquisition in this Agreement or in any exhibit, certificate,
schedule or financial statement delivered hereunder, or by reason of any claim,
action or proceeding asserted or instituted growing out of any matter or thing
covered by such representations, warranties or covenants.

     9.3 Exclusions. Notwithstanding Sections 9.1 and 9.2:

          (a) no indemnification shall be payable to the extent any claim is
covered by insurance; and

          (b) no indemnification shall be payable with respect to claims
asserted more than five (5) years after the Closing.

     9.4 Notice: Defense of Claims. Prompt written notice of each claim for
indemnification hereunder shall be given to the other party, specifying the
amount and nature of the claim, and of any matter which in the opinion of the
claimant is likely to give rise to an indemnification claim. The indemnifying
party shall have the right to participate at its own expense in the defense of
any such matter or its settlement. If, in the opinion of the indemnified party,
its financial condition or business would not be impaired thereby, such party
may authorize the indemnifying party to take over the defense of such matter so
long as such defense is expeditious. Failure to give notice of a matter which
may give rise to an indemnification claim shall not affect the rights of any
party to collect such claim from the other party or its transferees in
liquidation.

     9.5 Payment of Claims; Alternative Dispute Resolution. Indemnification
claims by OMEGA or Acquisition may be paid or otherwise satisfied as an offset
against the Purchase Note as set forth under Section 9.1, and, in the
alternative or after any such offset, the indemnification claims (or any balance
thereof) shall be paid or otherwise satisfied by Dr. Schmisseur, or Dr.
Schmisseur's transferees in liquidation, within 30 days after notice thereof is
given by OMEGA or Acquisition. In the event an indemnification claim is made by
any party and the indemnifying party disputes the nature or amount of the claim,
such dispute shall be referred to the American Arbitration Association to be
settled by alternative dispute resolution in accordance with the commercial
alternative dispute resolution rules of said Association, with the fees and
expenses thereof to be borne 50% by Acquisition and 50% by the New PC and Dr.
Schmisseur. If the 



                                      -9-
<PAGE>

indemnifying party is New PC or Dr. Schmisseur, the arbitration shall be held in
Boston, Massachusetts, and if the indemnifying party is OMEGA or Acquisition,
the arbitration shall be held in Chicago, Illinois.

                                   ----------

                        Representations and Warranties of
         Dr. Schmisseur and Orthodontic Entity to OMEGA and Acquisition

     Each of the Orthodontic Entity and Dr. Schmisseur hereby represents and
warrants to OMEGA and Acquisition as follows:

     1. Organization and Qualification of the Orthodontic Entity. The
Orthodontic Entity is a duly formed and organized professional corporation under
the laws of the State. The Orthodontic Entity is a legally existing professional
corporation under the State Professional Corporation Act (the "Act") and no
event has occurred which alone or after the passage of time would result in the
dissolution of the Orthodontic Entity. The Orthodontic Entity has the full power
to conduct business as currently conducted by the Orthodontic Entity and to own
and lease the property it purports to own. The copies of any articles of
organization or incorporation and by-laws, as defined in the Act, of the
Orthodontic Entity which are currently in effect, and all amendments thereto
(collectively, the "Charter and By-Laws"), certified by Dr. Schmisseur, attached
hereto as Exhibit D are complete and correct.

     2. Authorization of Transaction. All necessary action, company or
otherwise, has been taken by the Orthodontic Entity to authorize the execution
of the Agreement by Dr. Schmisseur, and the delivery and performance of this
Agreement and the transactions contemplated hereby, and the Agreement is the
valid and binding obligation of the Orthodontic Entity and Dr. Schmisseur,
enforceable against the Orthodontic Entity and Dr. Schmisseur in accordance with
its terms.

     3. Present Compliance with Obligations and Laws. Except as disclosed on
Exhibit X attached to this Schedule, there is not: (a) any violation of the
Charter or By-Laws; (b) a default in the performance of any obligation,
agreement or condition of any debt instrument from Dr. Schmisseur or the
Orthodontic Entity which (with or without the passage of time or the giving of
notice) affords to any person the right to accelerate any material indebtedness
or terminate any right; (c) a default of or breach of (with or without the
passage of time or the giving of notice) any other contract to which Dr.
Schmisseur or the Orthodontic Entity is a party or by which their assets are
bound; or (d) any violation of any law, regulation, administrative order or
judicial order applicable to Dr. Schmisseur or the Orthodontic Entity, or their
business or assets.

     4. No Conflict of Transaction With Obligations and Laws.

     (a) Neither the execution, delivery and performance of this Agreement, nor
the performance of the transactions contemplated hereby, will: (i) constitute a
breach or violation of Orthodontic Entity's Charter or By-Laws; (ii) conflict
with or constitute (with or without the passage of time or the giving of notice)
a breach of, or default under, any debt instrument to which Dr. Schmisseur or
the Orthodontic Entity is a party, or give any person the right to accelerate
any indebtedness or terminate any right; (iii) constitute (with or without the
passage of 



                                      -20-
<PAGE>

time or giving of notice) a default under or breach of any other agreement,
instrument or obligation to which the Orthodontic Entity or Dr. Schmisseur is a
party or by which their assets are bound; or (iv) result in a violation of any
law, regulation, administrative order or judicial order applicable to the
Orthodontic Entity, Dr. Schmisseur, their business or assets.

     (b) Except as disclosed on the attached Exhibit X to this Schedule, the
execution, delivery and performance of this Agreement and the transactions
contemplated hereby by the Orthodontic Entity do not require the consent,
waiver, approval, authorization, exemption of or giving of notice to any
governmental authority.

     5. Investigations and Licenses.

     (a) The Orthodontic Entity and Dr. Schmisseur have all necessary licenses
to practice orthodontics in the State.

     (b) Neither the Orthodontic Entity nor Dr. Schmisseur is subject to any
investigation, whether threatened, current or pending, under which the
Orthodontic Entity or Dr. Schmisseur may be required to forfeit or suffer the
revocation, suspension or limitation of Dr. Schmisseur's or the Orthodontic
Entity's license to practice orthodontics and neither the Orthodontic Entity nor
Dr. Schmisseur is subject to any investigation, whether threatened, current or
pending by a commercial third-party payor.

     6. Financial Statement. Attached as Exhibit A to the Agreement is the
Financial Statement of the Orthodontic Entity. To the best knowledge of Dr.
Schmisseur, the Financial Statement is complete and correct and fairly presents
in all material respects the financial position of the Orthodontic Entity as at
the date of such statement and the results of its operations for the period then
ended, in accordance with generally accepted accounting principles consistently
applied throughout the periods covered thereby for the periods covered thereby.

     7. Capitalization and the Interests. The authorized capital of the
Orthodontic Entity consists of the Interests. All of the Interests have been
validly issued and are fully paid and non-assessable. There are no options,
warrants, rights or other agreements or commitments obligating the Orthodontic
Entity or Dr. Schmisseur to issue or sell the Interests and there are no
pre-emptive rights with respect to any Interests. Dr. Schmisseur is the
beneficial and record owner of the Interests. Dr. Schmisseur has good title to
the Interests, free and clear of any liens, encumbrances or restrictions of any
kind. The Interests are not subject to any voting or similar agreement.

     8. Property; Liens; Condition.

     (a) Except as set forth on Exhibit X to this Schedule, the Orthodontic
Entity has good and marketable title in fee simple to all of its owned real and
personal property, including without limitation, all machinery and equipment
used or owned by the Orthodontic Entity (the "Equipment") free of liens and
encumbrances (the "Property"). All the Property owned or leased 




                                      -21-
<PAGE>

by the Orthodontic Entity is in good repair, has been well maintained,
substantially conforms with all applicable ordinances, regulations and zoning or
other laws. The Equipment is in good working order.

     (b) No other entity or person owns any of the assets necessary for the
operation of the Orthodontic Entity. The Orthodontic Entity does not operate any
of its practice through any other entities or persons.

     9. Payment of Taxes. The Orthodontic Entity has filed all federal, state
and local income, excise or franchise tax returns, real estate and personal
property tax returns, sales and use tax returns and other tax returns required
to be filed and has paid all taxes owing except taxes which have not yet accrued
or otherwise become due for which adequate provision has been made in the
Financial Statement. All transfer, excise or other taxes payable by reason of
the Merger pursuant to the Agreement shall be paid or provided for by the
Orthodontic Entity after the Closing out of the Consideration to be received
upon consummation of the Merger.

     10. Absence of Undisclosed Liabilities and Changes.

     (a) As of the date of the Financial Statement, the Orthodontic Entity had
no liabilities of any nature, whether accrued, absolute, contingent or otherwise
(including without limitation liabilities as guarantor or otherwise with respect
to obligations of others, or liabilities for taxes due or then accrued or to
become due), except (i) liabilities stated or adequately reserved against on the
Financial Statement, (ii) liabilities not in excess of $5,000 arising in the
ordinary course of business since the date of the Financial Statement, and (iii)
liabilities disclosed in Exhibit X to this Schedule. There is no fact which
materially adversely affects, or may in the future (so far as can now be
reasonably foreseen) materially adversely affect, the business, properties,
operations or condition of the Orthodontic Entity which has not been
specifically disclosed herein or in Exhibit X to this Schedule.

     (b) Except as disclosed in Exhibit X to this Schedule, since the date of
the Financial Statement there has not been:

          (i) any change in the financial condition, properties, assets,
liabilities, business or operations of the Orthodontic Entity, which change by
itself or in conjunction with all other such changes, whether or not arising in
the ordinary course of business, has been materially adverse with respect to the
Orthodontic Entity;

          (ii) any mortgage, encumbrance or lien placed on any of the Interests
or the Property, or the property subject to any lease, or which remains in
existence on the date hereof or at the time of Closing; or

          (iii) any obligation or liability incurred by the Orthodontic Entity
other than obligations and liabilities incurred in the ordinary course of
business and disclosed on Exhibit X attached to this Schedule.

knowledge of the Orthodontic Entity or Dr. Schmisseur, threatened against the
Orthodontic Entity or Dr. Schmisseur, at law or in equity, or before or by any
Federal, state, municipal or other governmental department, commission, board,
bureau, agency or instrumentality or governmental inquiry pending or, to the
knowledge of the Orthodontic Entity or Dr. Schmisseur, threatened against or

Section 9.3, Dr. Saydyk agrees to defend, indemnify and hold OMEGA harmless from
and against any damages, liabilities, losses and expenses (including reasonable
counsel fees) of any kind or nature whatsoever which may be sustained or
suffered by OMEGA based upon a breach of any representation, warranty or
covenant made by the Orthodontic Entity or Dr. Saydyk in this Agreement or in
any exhibit, certificate, schedule or financial statement delivered hereunder,
or by reason of any claim, action or proceeding asserted or instituted growing
out of any matter or 


                                      -8-
<PAGE>


thing covered by such representations, warranties or covenants. OMEGA may at
their option recover such indemnification claims by OMEGA by set off against
amounts of principal and interest due under the Purchase Note, but shall not be
required to recover said claims in such manner and may proceed against Dr.
Saydyk and his transferee in liquidation at any time or times for recovery of
indemnification claims.

     9.2 Indemnification By OMEGA. Subject to the limitations set forth in
Section 9.3, OMEGA agrees to defend, indemnify and hold Dr. Saydyk harmless from
and against any damages, liabilities, losses and expenses (including reasonable
counsel fees) of any kind or nature whatsoever which may be sustained or
suffered by Dr. Saydyk based upon a breach of any representation, warranty or
covenant made by OMEGA in this Agreement or in any exhibit, certificate,
schedule or financial statement delivered hereunder, or by reason of any claim,
action or proceeding asserted or instituted growing out of any matter or thing
covered by such representations, warranties or covenants.

     (a) no indemnification shall be payable to the extent any claim is covered
by insurance; and

indemnification hereunder shall be given to the other party, specifying the
amount and nature of the claim, and of any matter which in the opinion of the
claimant is likely to give rise to an indemnification claim. The indemnifying
party shall have the right to participate at its own expense in the defense of
any such matter or its settlement. If, in the opinion of the indemnified party,
its financial condition or business would not be impaired thereby, such party
may authorize the indemnifying party to take over the defense of such matter so
long as such defense is expeditious. Failure to give notice of a matter which
may give rise to an indemnification claim shall not affect the rights of any
party to collect such claim from the other party or its transferees in
liquidation.

      9.5 Payment of Claims; Alternative Dispute Resolution. (a) Indemnification
claims by OMEGA may be paid or otherwise satisfied as an offset against the
Purchase Note as set forth under Section 9.1, and, in the alternative or after
any such offset, indemnification claims by OMEGA shall be paid or otherwise
satisfied by Dr. Saydyk, or Dr. Saydyk's transferees in liquidation, within 30
days after notice thereof is given by OMEGA. In the event Dr. Saydyk indicates
in a writing delivered to OMEGA that he disputes the nature or amount of the
claim, in which event the dispute upon the election of any party hereto after
said 30-day period shall be settled in accordance with Section 9.5(b).

The parties will meet and attempt in good faith to resolve any controversy or

     10.5 Entire Agreement. This Agreement (including all exhibits or schedules
appended to this Agreement and all documents delivered pursuant to the
provisions of this Agreement, all of which are hereby incorporated herein by
reference) together with the Management Services Agreement and the Stock
Put/Call Option and Successor Designation Agreement (including all exhibits and
schedules thereto), taken together, constitute the entire agreement between the
parties, and all promises, representations, understandings, warranties and
agreements with reference to the subject matter hereof and inducements to the
making of this Agreement relied upon by my party hereto, have been expressed

     10.6 Binding Agreement, Successors. This Agreement shall be binding upon,
and shall be enforceable by and inure to the benefit of, the parties named
herein and their respective successors and assigns; provided, however, that this
Agreement may not be assigned by any of the parties without the prior written
consent of all the other parties.

     10.7 Confidentiality. As used herein, "Confidential Information" means any
information or data that a party has acquired from another party that is
confidential or not otherwise available to the public, whether oral or written,
including without limitation any analyses, computations, studies or other
documents prepared from such information or data by or for the directors,
officers, employees, agents or representatives of such party (collectively, the
"Representatives"), but excluding information or data which (i) became available
to the public other than as a result of such party's violation of this
Agreement, (ii) became available to such party from a source other than the
other party if that source was not bound by a confidentiality agreement with
such other party and such source lawfully obtained such information or data, or
(iii) is required to be disclosed by applicable law, provided that promptly
after being compelled to disclose any such information or data, the party being
so compelled shall provide prompt notice thereof to the other party so that such
other party may seek a protective order or other appropriate remedy. Each party
covenants and agrees that it and its Representatives shall keep confidential and
shall not disclose all Confidential Information, except to its Representatives
and lenders who need to know such


                                      -11-

for any breach of this provision by its Representatives. In the event that the
Closing does not occur, each party will promptly return to the other all copies
of such other party's Confidential Information.

      10.8 Governing Law; Severability. This Agreement shall be deemed a
contract made under the laws of the State of Delaware and, together with the
rights and obligations of the parties hereunder, shall be construed under and
governed by the laws of such state. The invalidity or unenforceability of any
provision of this Agreement shall not affect the validity or enforceability of
any other provision hereof.

payment to the other party or any affiliate of the other party of any cash or
other remuneration whether directly or indirectly, overtly or covertly,
specifically for patient referrals or for recommending or arranging the
purchase, lease or order of any item or service. The Consideration to be

Orthodontic Entity and is not in any way related to or dependent upon referrals
by and between OMEGA, Acquisition and Dr. Saydyk.

     10.10 Further Assurances. Following the execution of this Agreement, Dr.
Saydyk, the Orthodontic Entity and OMEGA each agrees:

constitute a material breach of any of the representations, warranties or
covenants of such party contained herein; and

     (c) to provide the other (or its counsel) promptly with copies of all
filings made by such party with any state or federal governmental entity in
connection with this Agreement or the transactions contemplated hereby.

                                    Exhibit F

                         Alternative Dispute Resolution

A. Method of Invoking ADR Procedures

     1. These procedures may be invoked by any party to an agreement which
incorporates these procedures by giving written notice to the other of the
dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties, each acting through its representative, shall meet at a
mutually acceptable time and place within five business days after the
non-disputing party designates its representative to the other. At that meeting,
the parties shall attempt in good faith to negotiate a resolution of the
dispute, or failing that, to agree on a method for resolving the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer period of time as the parties may mutually agree, the parties have not
succeeded in negotiating a resolution of the claim or dispute or agreeing on a
dispute resolution mechanism, they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

     4. The parties will jointly appoint a mutually acceptable mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above, then the parties shall select a neutral third party from
the Center for Public Resources, New York, New York ("CPR") Panels of Neutrals,
with the assistance of CPR, unless the parties agree otherwise in finding a
mutually acceptable mediator.

     5. The New PC and the MSO shall each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR.

     6. The parties agree to participate in good faith in the mediation and
negotiations related thereto for a period of thirty (30) days from appointment
of a mediator by any of the parties or the CPR.


B. Mediation procedures

     1. The mediator shall be neutral and impartial.

     2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.


                                      -19-
<PAGE>


      (a)   The mediator is free to meet and communicate separately with each
            party.

      (b)   The mediator will decide when to hold joint meetings with the
            parties and when to hold separate meetings. There shall be no
            stenographic record of any meeting. Formal rules of evidence will
            not apply.

      (c)   The mediator may request that there be no direct communication
            between the parties or between their attorneys without the
            concurrence of the mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its officers and an attorney. Each party will have a representative fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator will not transmit information received from any party to
another party or any third person unless authorized to do so by the party
transmitting the information.

     6. The entire process is confidential. The parties and the mediator will
not disclose information regarding the process, including settlement terms, to
third persons, unless the parties otherwise agree. The process shall be treated
as a compromise negotiation for purposes of the Federal Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing administrative and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

      (a)   The mediator will be disqualified as a witness, consultant or expert
            in any pending or future investigation, action or proceeding
            relating to the subject matter of the mediation (including any
            investigation, action or proceeding which involves persons not party
            to this mediation); and

      (b)   The mediator and any documents and information in the mediator's
            possession will not be subpoenaed in any such investigation, action
            or proceeding, and all parties will oppose any effort to have the
            mediator and documents subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.


                                      -20-
<PAGE>


     10. The mediator, if a lawyer, may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons, (ii) if the mediator believes that a party
is not acting in good faith, or (iii) if the mediator concludes that further
mediation efforts would not be useful.

C. Binding Arbitration If the parties do not resolve the dispute through
mediation within the period provided in Part A above, the parties shall submit
the matter to binding arbitration in Boston, Massachusetts before a qualified
sole arbitrator in accordance with the then current CPR Rules for
Non-Administered Arbitration of Business Disputes. If the party initially
raising the dispute to be resolved is New PC or Dr. Saydyk, the arbitration
shall be held in Boston, Massachusetts, and if the party initially raising the
dispute to be resolved is the MSO or OMEGA, the arbitration shall be held in
Denver, Colorado. The sole arbitrator shall be agreed upon by the parties within
twenty (20) days after either party elects to submit any issue to arbitration
or, failing that, shall be selected by CPR. A qualified arbitrator is one who is
familiar with the principal subject matter of the issues to be arbitrated such
as by way of example, healthcare services industry matters, management
consulting services generally or business law/corporate matters generally.
Judgment upon the award rendered by the arbitrator may be entered in any court
having jurisdiction. The arbitrator shall not have the authority to award
multiple, punitive or consequential damages under any circumstances.

and lease the property it purports to own. The copies of any articles of
organization or incorporation and by-laws, as defined in the Act, of the

Exhibit X attached to this Schedule, there is not: (a) any violation of the
Charter or By-Laws; (b) a default in the performance of any obligation,

Entity which (with or without the passage of time or the giving of notice)
affords to any person the right to accelerate any material indebtedness or
terminate any right; (c) a default of or breach of (with or without the passage
of time or the giving of notice) any other contract to which Dr. Saydyk or the

applicable to Dr. Saydyk or the Orthodontic Entity, or their business or assets.

     4. No Conflict of Transaction With Obligations and Laws.

     (a) Neither the execution, delivery and performance of this Agreement, nor
the performance of the transactions contemplated hereby, will: (i) constitute a
breach or violation of Orthodontic Entity's Charter or By-Laws; (ii) conflict
with or constitute (with or without the passage of time or the giving of notice)
a breach of, or default under, any debt instrument to which Dr. Saydyk or the
Orthodontic Entity is a party, or give any person the right to accelerate any
indebtedness or terminate any right; (iii) constitute (with or without the
passage of time or giving of notice) a default under or breach of any other

assets.

      (b) Except as disclosed on the attached Exhibit X to this Schedule, the

     5. Investigations and Licenses.

     (a) The Orthodontic Entity and Dr. Saydyk have all necessary licenses to
practice orthodontics in the State.

     (b) Neither the Orthodontic Entity nor Dr. Saydyk is subject to any

license to practice orthodontics and neither the Orthodontic Entity nor Dr.
Saydyk is subject to any investigation, whether threatened, current or pending

Orthodontic Entity after the Closing out of the Consideration to be received
upon consummation of the Merger.

     by itself or in conjunction with all other such changes, whether or not
     arising in the ordinary course of business, has been materially adverse
     with respect to the Orthodontic Entity;

          (ii) any mortgage, encumbrance or lien placed on any of the Interests
     or the Property, or the property subject to any lease, or which remains in
     existence on the date hereof or at the time of Closing; or

          (iii) any obligation or liability incurred by the Orthodontic Entity
     other than obligations and liabilities incurred in the ordinary course of
     business and disclosed on Exhibit X attached to this Schedule.

      11. Litigation. Except for matters described on Exhibit X to this
Schedule, there is no action, suit, claim, proceeding or investigation pending

("Dr. Feldman"), who is duly licensed to practice orthodontics in the state of

stock of the Orthodontic Entity (the issued and outstanding capital stock is

any exhibit, certificate, schedule or financial statement delivered hereunder,
or by reason of any claim, action or proceeding asserted or instituted growing
out of any matter or thing covered by such representations, warranties or
covenants. OMEGA may at their option recover such indemnification claims by

Section 9.3, OMEGA agrees to defend, indemnify and hold Dr. Feldman harmless
from and against any damages, liabilities, losses and expenses (including
reasonable counsel fees) of any kind or nature whatsoever which may be sustained
or suffered by Dr. Feldman based upon a breach of any representation, warranty
or covenant made by OMEGA in this Agreement or in any exhibit, certificate,
schedule or financial statement delivered hereunder, or by reason of any claim,
action or proceeding asserted or instituted growing out of any matter or thing
covered by such representations, warranties or covenants.

amount and nature of the claim, and of any matter which in the opinion of the

party shall have the right to participate at its own expense in the defense of
any such matter or its settlement. If, in the opinion of the indemnified party,
its financial condition or business would not be impaired thereby, such party
may authorize the indemnifying party to take over the defense of such matter so
long as such defense is expeditious. Failure to give notice of a matter which
may give rise to an indemnification claim shall not affect the rights of any
party to collect such claim from the other party or its transferees in
liquidation.

     9.5 Payment of Claims; Alternative Dispute Resolution. (a) Indemnification
claims by OMEGA may be paid or otherwise satisfied as an offset against the

liquidation, within 30 days after notice thereof is given by OMEGA. In the event
Dr. Feldman indicates in a writing delivered to OMEGA that he disputes the
nature or amount of the claim, in which event the dispute upon the election of
any party hereto after said 30-day period shall be settled in accordance with
Section 9.5(b).

     (b) If a dispute arises under this Agreement that cannot be resolved
informally by the parties, any party may invoke the procedures set forth in
Exhibit E hereto and the parties agree to use these procedures, except paragraph
(c) of this Section 9.5, prior to any party pursuing other available remedies.
The parties will meet and attempt in good faith to resolve any controversy or
claim arising out of or relating to this Agreement.

     (c) Notwithstanding anything in this Section 9.5 to the contrary,nothing
shall preclude any party from seeking a preliminary injunction or other
provisional relief, either prior to or during the proceeding provided for in
this section, if in its judgment such action is necessary to avoid irreparable
damage or to



                                      -9-

preserve the status quo.

confidential or not otherwise available to the public, whether oral or written,
including without limitation any analyses, computations, studies or other
documents prepared from such information or data by or for the directors,
officers, employees, agents or representatives of such party (collectively, the
"Representatives"), but excluding information or data which (i) became available
to the public other than as a result of such party's violation of this

so compelled shall provide prompt notice thereof to the other party so that such
other party may seek a protective order or other appropriate remedy. Each party

<PAGE>

under the laws of the State of Delaware and, together with the rights and
obligations of the parties hereunder, shall be construed under and governed by
the laws of such state. The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other

constitute a material breach of any of the representations, warranties or
covenants of such party contained herein; and

     (c) to provide the other (or its counsel) promptly with copies of all
filings made by such party with any state or federal governmental entity in

                                    EXHIBIT F

A.   Method of Invoking ADR Procedures

     1. These procedures may be invoked by any party to an agreement which
incorporates these procedures by giving written notice to the other of the
dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties, each acting through its representative, shall meet at a
mutually acceptable time and place within five business days after the
non-disputing party designates its representative to the other. At that meeting,
the parties shall attempt in good faith to negotiate a resolution of the
dispute, or failing that, to agree on a method for resolving the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer period of time as the parties may mutually agree, the parties have not
succeeded in negotiating a resolution of the claim or dispute or agreeing on a
dispute resolution mechanism, they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

     4. The parties will jointly appoint a mutually acceptable mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above, then the parties shall select a neutral third party from
the Center for Public Resources, New York, New York ("CPR") Panels of Neutrals
or the American Arbitration Association ("AAA"), with the assistance of CPR/AAA,
unless the parties agree otherwise in finding a mutually acceptable mediator.

     5. The New PC and the MSO shall each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR/AAA.

     6. The parties agree to participate in good faith in the mediation and
negotiations related thereto for a period of thirty (30) days from appointment
of a mediator by any of the parties or the CPR/AAA.

B.   Mediation procedures

     1. The mediator shall be neutral and impartial.

     2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.


                                      -19-
<PAGE>


          (a)  The mediator is free to meet and communicate separately with each
               party.

          (b)  The mediator will decide when to hold joint meetings with the
               parties and when to hold separate meetings. There shall be no
               stenographic record of any meeting. Formal rules of evidence will
               not apply.

          (c)  The mediator may request that there be no direct communication
               between the parties or between their attorneys without the
               concurrence of the mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its officers and an attorney. Each party will have a representative fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator will not transmit information received from any party to
another party or any third person unless authorized to do so by the party
transmitting the information.

     6. The entire process is confidential. The parties and the mediator will
not disclose information regarding the process, including settlement terms, to
third persons, unless the parties otherwise agree. The process shall be treated
as a compromise negotiation for purposes of the Federal Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing administrative and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

          (a)  The mediator will be disqualified as a witness, consultant or
               expert in any pending or future investigation, action or
               proceeding relating to the subject matter of the mediation
               (including any investigation, action or proceeding which involves
               persons not party to this mediation); and

          (b)  The mediator and any documents and information in the mediator's
               possession will not be subpoenaed in any such investigation,
               action or proceeding, and all parties will oppose any effort to
               have the mediator and documents subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.

     10. The mediator, if a lawyer, may freely express views to the parties on
the legal 


                                      -20-
<PAGE>

     issues of the dispute.

     11. The mediator shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons, (ii) if the mediator believes that a party
is not acting in good faith, or (iii) if the mediator concludes that further
mediation efforts would not be useful.

     C.   Binding Arbitration

     If the parties do not resolve the dispute through mediation within the
period provided in Part A above, the parties shall submit the matter to binding
arbitration in Boston, Massachusetts before a qualified sole arbitrator in
accordance with the then current CPR Rules for Non-Administered Arbitration of
Business Disputes or comparable AAA rules. The arbitration shall be held in
Woodland Hills, California. The sole arbitrator shall be agreed upon by the
parties within twenty (20) days after either party elects to submit any issue to
arbitration or, failing that, shall be selected by CPR/AAA. A qualified
arbitrator is one who is familiar with the principal subject matter of the
issues to be arbitrated such as by way of example, healthcare services industry
matters, management consulting services generally or business law/corporate
matters generally. Judgment upon the award rendered by the arbitrator may be
entered in any court having jurisdiction. The arbitrator shall not have the
authority to award multiple, punitive or consequential damages under any
circumstances.

the performance of the transactions contemplated hereby, will: (i) constitute a
breach or violation of Orthodontic Entity's Charter or By-Laws; (ii) conflict

             AFFILIATION AGREEMENT AND AGREEMENT AND PLAN OF MERGER

      THIS AFFILIATION AGREEMENT AND AGREEMENT AND PLAN OF MERGER is entered
into as of the 29th day of March 1997, by and among Omega Orthodontics, Inc., a
Delaware corporation ("OMEGA"); Jeff S. Zapalac, D.D.S. ("Dr. Zapalac"), who is
duly licensed to practice orthodontics in the state of Texas (the "State"); Jeff
S. Zapalac, D.D.S., M.S., Inc., a Texas professional corporation (the
"Orthodontic Entity"); and Omega Orthodontics of Austin, Inc., a Delaware
corporation to be formed and to become a wholly owned subsidiary of OMEGA
("Acquisition" and sometimes referred to herein as the "Surviving Entity") (and
which shall have joined herein by subsequently executing this Agreement).

                                    RECITALS

      A. OMEGA provides professional management and marketing services to
orthodontic practices in the United States, which services include providing
practice management systems, office space, equipment, furnishings and active
administrative personnel necessary for the operation of orthodontic practices,
and which services are provided directly or indirectly through management
service organizations.

      B. The Orthodontic Entity owns and operates an orthodontic practice with
offices located at 8430 Spicewood Springs Road, Austin, Texas 78759 (the
"Orthodontic Offices") and furnishes orthodontic care to the general public
through the services of Dr. Zapalac affiliated with the Orthodontic Entity.

      C.    Dr. Zapalac presently holds 100% of the issued and outstanding
capital stock of the Orthodontic Entity (the issued and outstanding capital
stock is hereafter referred to herein as the "Interests").

      D.    Dr. Zapalac owns all of the Interests, and desires to convert the
status of the Orthodontic Entity from a professional entity to a general
purpose entity and to form a new professional corporation or entity to
continue his orthodontic practice at the Orthodontic Offices.

      E. OMEGA has conducted a review of the Orthodontic Entity, and has
reviewed the Orthodontic Entity's unaudited financial and operations statement
provided by Dr. Zapalac (the "Financial Statement"), a copy of which is attached
hereto as Exhibit A . Based on its review of the Orthodontic Entity and the
Financial Statement, OMEGA has issued the report (the "Report"), a copy of which
has been furnished to the Orthodontic Entity. The Orthodontic Entity and Dr.
Zapalac have reviewed the Report and OMEGA's literature, and agree with the
Report and the concepts of OMEGA's Exceptional Practice.

      F. Subject to the terms and conditions of this Agreement, OMEGA and Dr.
Zapalac have determined that it is in the best interests of each to effect a
merger of the Orthodontic Entity

with and into Acquisition (the "Merger") as provided in Section 2.1 hereof.

      NOW, THEREFORE, in consideration of the foregoing recitals and the mutual
promises contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged to the full
satisfaction of the parties hereto, the parties hereto agree as follows:


                  ARTICLE I. ENTITY FORMATION AND CONVERSION

      1.1 At the Closing (as defined in Section 2.3 hereof), Dr. Zapalac shall
cause the Orthodontic Entity's charter ("Charter") to be amended to convert the
Orthodontic Entity into a general purpose entity under the laws of the State.

      1.2 Dr. Zapalac shall form a new professional entity (the "New PC") under
the laws of the State and, in accordance with the terms of this Agreement,
commence the practice of orthodontics through the New PC.

      1.3 OMEGA shall form Acquisition and shall cause Acquisition to join in
this Agreement by subsequently executing this Agreement where indicated below.


                               ARTICLE II. MERGER

      2.1  Merger; Consideration and Payment.

      (a) At the Effective Time (as hereinafter defined) and subject to the
terms and conditions hereinafter set forth, the parties hereto agree to cause
the Merger to be consummated by filing with the Delaware Secretary of State and
the State Secretary of State (if required) a Certificate of Merger (the
"Certificate of Merger") in the form required by applicable law, duly executed
and acknowledged by the Surviving Entity, and taking all such further actions as
may be required by law to make the Merger effective. The Merger shall become
effective upon the filing of the Certificate of Merger with the Delaware
Secretary of State and the State Secretary of State (if required) (the
"Effective Time"), and Acquisition will be the surviving entity.

      (b) At the Effective Time, the Interests of Orthodontic Entity outstanding
immediately prior to the Effective Time shall, on such date, by virtue of the
Merger and upon surrender to OMEGA of the certificates therefor, duly endorsed
and transferable, free and clear of any liens, encumbrances, restrictions or
claims of any kind (other than those liens, encumbrances, restrictions and
claims expressly disclosed to OMEGA and affirmatively accepted by OMEGA prior to
the Effective Time), without any further action on the part of any holder
thereof, be converted into the right to receive an aggregate consideration (the
"Consideration") of:

            (i) Five Hundred Thousand Dollars ($500,000.00) in cash (the "Cash
      Component"); and

            (iii) Five Hundred Thousand Dollars ($500,000.00) to be represented
      by issuance to Dr. Zapalac of an option to purchase shares of OMEGA common
      stock ("OMEGA Stock") at any time within five years of the IPO Closing (as
      defined below in Section 2.3), based on a value per share equal to 100% of
      the IPO Price (as defined below in Section 2.3) (the "Option Component"),
      if the option is exercised, the OMEGA Stock shall thereupon be issued to
      Dr. Zapalac, fully paid and nonassessable.

      (c) At the Effective Time, each share of stock of Acquisition outstanding
immediately prior to the Effective Time shall, on such date, by virtue of the
Merger and without any action on the part of any holder thereof, continue and
shall be held by OMEGA.

      2.2   Adjustment and Audit.

      (a) The Consideration is based on the value of the Interests as determined
by OMEGA from the information set forth in the Financial Statement. At OMEGA's
option, OMEGA will cause an audit (the "Audit") of the Financial Statement and
the books and records of the Orthodontic Entity to be completed prior to Closing
to confirm the accuracy and completeness of the information in the Financial
Statement.

      (b) The Consideration shall be subject to adjustments at Closing for: (i)
prepaid and underpaid rent and other lease obligations, if the leases are to be
continued after Closing, as well as for other agreed normal and customary
prepaid and underpaid expenses; (ii) any accrued but unpaid salaries, bonuses
and other compensation, fringe and health insurance benefits, employment or
payroll taxes and related employment obligations and (iii) any accounts payable
of the Orthodontic Entity which have accrued prior to the Effective Time and
which remain unpaid as of such time (the "Accounts Payable") in excess of an
amount equal to one-half (1/2) of one "Average" month of gross income from the
Orthodontic Entity. As used herein, Average shall mean an average of the
Accounts Payable of the Orthodontic Entity using the last twelve months prior to
the end of the month immediately preceding the Effective Time.

      (c) The adjustments to the Consideration, if any, shall be applied in the
following order of priority; first to the Cash Component, and the balance, if
any, to the Option Component.

      2.3 Time and Place of Closing. The closing of the transactions
contemplated hereby (herein called the "Closing") shall be held immediately
before the Effective Time at the offices of Robinson & Cole, One Boston Place,
Boston, Massachusetts 02108 on the date of the closing of OMEGA's initial public
offering of its securities (the "IPO Closing") pursuant to an effective
registration statement under the Securities Act of 1933, as amended (the
"Securities Act") ("IPO"), or at such other place, date or time as may be fixed
by mutual agreement of the parties; provided, however, that in no event shall
the Closing date be extended beyond June 30, 1997. On or before the IPO Closing,
OMEGA will notify the Orthodontic Entity of the projected IPO Closing Date
determined by OMEGA, in its sole discretion. As used herein "IPO Price" shall
mean the initial offering price to the public of OMEGA Stock as reflected on the
cover page of its Prospectus under the Securities Act for the IPO.

<PAGE>



      9.2 Indemnification By OMEGA and Acquisition. Subject to the limitations
set forth in Section 9.3, OMEGA and Acquisition, jointly and severally, each
agrees to defend, indemnify and hold Dr. Zapalac harmless from and against any
damages, liabilities, losses and expenses (including reasonable counsel fees) of
any kind or nature whatsoever which may be sustained or suffered by Dr. Zapalac
based upon a breach of any representation, warranty or covenant made by OMEGA or
Acquisition in this Agreement or in any exhibit, certificate, schedule or
financial statement delivered hereunder, or by reason of any claim, action or
proceeding asserted or instituted growing out of any matter or thing covered by
such representations, warranties or covenants.

      9.3 Exclusions. Notwithstanding Sections 9.1 and 9.2:

      (a) no indemnification shall be payable to the extent any claim is covered
by insurance; and

      (b) no indemnification shall be payable with respect to claims asserted
more than five (5) years after the Closing.

      9.4 Notice: Defense of Claims. Prompt written notice of each claim for
indemnification hereunder shall be given to the other party, specifying the
amount and nature of the claim, and of any matter which in the opinion of the
claimant is likely to give rise to an indemnification claim. The indemnifying
party shall have the right to participate at its own expense in the defense of
any such matter or its settlement. If, in the opinion of the indemnified party,
its financial condition or business would not be impaired thereby, such party
may authorize the indemnifying party to take over the defense of such matter so
long as such defense is expeditious. Failure to give notice of a matter which
may give rise to an indemnification claim shall not affect the rights of any
party to collect such claim from the other party or its transferees in
liquidation.

      9.5 Payment of Claims; Alternative Dispute Resolution. (a) Any
indemnification claims shall be paid or otherwise satisfied by Dr. Zapalac, or
Dr. Zapalac's transferees in liquidation, within 30 days after notice thereof is
given by OMEGA or Acquisition. In the event Dr. Zapalac indicates in a writing
delivered to OMEGA and Acquisition that he disputes the nature or amount of the
claim, in which event the dispute upon the election of any party hereto after
said 30-day period shall be handled in accordance with this Section.

      (b) If a dispute arises under this Agreement which cannot be resolved
informally by the parties, any party may invoke the procedures set forth in
Exhibit D hereto and the parties agree to use these procedures, except paragraph
(c) of this Section 9.5, prior to any party pursuing other available remedies.
The parties will meet and attempt in good faith to resolve any controversy or
claim arising out of or relating to this Agreement.

      (c) Notwithstanding anything in this Section 9.5 to the contrary, nothing
in this Section 9.5 shall preclude any party from seeking a preliminary
injunction or other provisional relief, either prior to or during the proceeding
provided for in this section, if in its judgment such



                                      -9-
<PAGE>



action is necessary to avoid irreparable damage or to preserve the status quo.

appended to this Agreement and all documents delivered pursuant to the
provisions of this Agreement, all of which are hereby incorporated herein by
reference) together with the Management Services Agreement and the Stock
Put/Call Option and Successor Designation Agreement (including all exhibits and
schedules thereto), taken together, constitute the entire agreement between the
parties, and all promises, representations, understandings, warranties and
agreements with reference to the subject matter hereof and inducements to the
making of this Agreement relied upon by my party hereto, have been expressed

      10.6 Binding Agreement, Successors. This Agreement shall be binding upon,
and shall be enforceable by and inure to the benefit of, the parties named
herein and their respective successors and assigns; provided, however, that this
Agreement may not be assigned by any of the parties without the prior written
consent of all the other parties.

      10.7 Confidentiality. As used herein, "Confidential Information" means any
information or data that a party has acquired from another party that is
confidential or not otherwise available to the public, whether oral or written,
including without limitation any analyses, computations, studies or other
documents prepared from such information or data by or for the directors,
officers, employees, agents or representatives of such party (collectively, the
"Representatives"), but excluding information or data which (i) became available
to the public other than as a result of such party's violation of this
Agreement, (ii) became available to such party from a source other than the
other party if that source was not bound by a confidentiality agreement with
such other party and such source lawfully obtained such information or data, or
(iii) is required to be disclosed by applicable law, provided that promptly
after being compelled to disclose any such information or data, the party being
so compelled shall provide prompt notice thereof to the other party so that such
other party may seek a protective order or other appropriate remedy. Each party
covenants and agrees that it and its Representatives shall keep confidential and

state. The invalidity or unenforceability of any provision of this Agreement
shall not affect the validity or enforceability of any other provision hereof.

                                    Exhibit E

ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A. Method of Invoking ADR Procedures

      1. These procedures may be invoked by any party to an agreement which
incorporates these procedures by giving written notice to the other of the
dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

      2. The parties, each acting through its representative, shall meet at a
mutually acceptable time and place within five business days after the
non-disputing party designates its representative to the other. At that meeting,
the parties shall attempt in good faith to negotiate a resolution of the
dispute, or failing that, to agree on a method for resolving the claim or
dispute.

      3. If, within ten (10) business days after the first meeting or within
such longer period of time as the parties may mutually agree, the parties have
not succeeded in negotiating a resolution of the claim or dispute or agreeing on
a dispute resolution mechanism, they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

      4. The parties will jointly appoint a mutually acceptable mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above, then the parties shall select a neutral third party from
either the Center for Public Resources, New York, New York ("CPR") Panels of
Neutrals, the American Arbitration Association ("AAA") or the Association of
Attorney Neutrals ("AAN"), with the assistance of such organization, unless the
parties agree otherwise in finding a mutually acceptable mediator.

      5. Acquisition shall bear 50% and the New PC and Dr. Zapalac shall bear
50% of the fees and costs of the mediator and any fees and costs of CPR, AAA or
AAN.

      6. The parties agree to participate in good faith in the mediation and
negotiations related thereto for a period of thirty (30) days from appointment
of a mediator by any of the parties or the CPR, AAA or AAN.


B.    Mediation procedures

      1. The mediator shall be neutral and impartial.



                                      -18-
<PAGE>



      2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.


      (a)   The mediator is free to meet and communicate separately with each
            party.

      (b)   The mediator will decide when to hold joint meetings with the
            parties and when to hold separate meetings. There shall be no
            stenographic record of any meeting. Formal rules of evidence will
            not apply.

      (c)   The mediator may request that there be no direct communication
            between the parties or between their attorneys without the
            concurrence of the mediator.

      3. Each party may be represented by more than one person, e.g., one or
more of its officers and an attorney. Each party will have a representative
fully authorized to negotiate a settlement of the dispute present.

      4. The process will be conducted expeditiously.

      5. The mediator will not transmit information received from any party to
another party or any third person unless authorized to do so by the party
transmitting the information.

      6. The entire process is confidential. The parties and the mediator will
not disclose information regarding the process, including settlement terms, to
third persons, unless the parties otherwise agree. The process shall be treated
as a compromise negotiation for purposes of the Federal Rules of Evidence and
state rules of evidence.

      7. The parties will refrain from pursuing administrative and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

      8. Unless all parties and the mediator otherwise agree in writing,

      (a)   The mediator will be disqualified as a witness, consultant or expert
            in any pending or future investigation, action or proceeding
            relating to the subject matter of the mediation (including any
            investigation, action or proceeding which involves persons not party
            to this mediation); and

      (b)   The mediator and any documents and information in the mediator's
            possession will not be subpoenaed in any such investigation, action
            or proceeding, and all parties will oppose any effort to have the
            mediator and documents subpoenaed.

      9. If the dispute goes into arbitration, the mediator shall not serve as
an arbitrator,

                                      -19-
<PAGE>


unless the parties and the mediator otherwise agree in writing.

      10. The mediator, if a lawyer, may freely express views to the parties on
the legal issues of the dispute.

      11. The mediator shall not be liable for any act or omission in connection
with the mediation.

      12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons, (ii) if the mediator believes that a party
is not acting in good faith, or (iii) if the mediator concludes that further
mediation efforts would not be useful.

C.    Binding Arbitration

      If the parties do not resolve the dispute through mediation within the
period provided in Part A above, the parties shall submit the matter to binding
arbitration before AAA, AAN or CPR, to a qualified sole arbitrator in accordance
with the then current CPR Rules for Non-Administered Arbitration of Business
Disputes or comparable AAA or AAN rules. The sole arbitrator shall be agreed
upon by the parties within twenty (20) days after either party elects to submit
any issue to arbitration or, failing that, shall be selected by the organization
to whom the parties selected for arbitration. A qualified arbitrator is one who
is familiar with the principal subject matter of the issues to be arbitrated
such as by way of example, healthcare services industry matters, management
consulting services generally or business law/corporate matters generally.
Judgment upon the award rendered by the arbitrator may be entered in any court
having jurisdiction. The arbitrator shall not have the authority to award
multiple, punitive or consequential damages under any circumstances. If the
party initially raising the dispute to be resolved is New PC or Dr. Zapalac, the
arbitration shall be held in Boston, Massachusetts, and if the party initially
raising the dispute to be resolved is the MSO or OMEGA, the arbitration shall be
held in Austin, Texas.

applicable to Dr. Zapalac or the Orthodontic Entity, or their business or
assets.

      4.  No Conflict of Transaction With Obligations and Laws.

the performance of the transactions contemplated hereby, will: (i) constitute a
breach or violation of Orthodontic Entity's Charter or By-Laws; (ii) conflict
with or constitute (with or without the passage of time or the giving of notice)
a breach of, or default under, any debt instrument to which Dr. Zapalac or the
Orthodontic Entity is a party, or give any person the right to accelerate any
indebtedness or terminate any right; (iii) constitute (with or without the
passage of time or giving of notice) a default under or breach of any other

Entity's license to practice orthodontics and neither the Orthodontic Entity nor
Dr. Zapalac is subject to any investigation, whether threatened, current or
pending by a commercial third-party payor.

into as of the 25th day of February, 1997, by and among Omega Orthodontics,
Inc., a Delaware corporation ("OMEGA"); David T. Grove, D.M.D., M.S. ("Dr.
Grove"), who is duly licensed to practice orthodontics in the state of Nevada

"Orthodontic Entity"); and Omega Orthodontics of Elko, Inc., a Delaware
corporation to be formed and to become a wholly owned subsidiary of OMEGA
("Acquisition" and sometimes referred to herein as the "Surviving Entity") (and
which shall have joined herein by subsequently executing this Agreement).

                                    RECITALS

      A. OMEGA provides professional management and marketing services to

and which services are provided directly or indirectly through management
service organizations.

      B. The Orthodontic Entity owns and operates an orthodontic practice with
offices located at 581 12th Street, Elko, Nevada (the "Orthodontic Offices") and
furnishes orthodontic care to the general public through the services of Dr.
Grove affiliated with the Orthodontic Entity.

      C.    Dr. Grove presently holds 100% of the membership interests of
the Orthodontic Entity (the issued and outstanding interests is hereafter
referred to herein as the "Interests").

      D.    Dr. Grove owns all of the Interests, and desires to convert the
Orthodontice Entity to a general purpose entity under the laws of the State
and to form a new professional corporation or entity to continue his
orthodontic practice at the Orthodontic Offices.

      E. OMEGA has conducted a review of the Orthodontic Entity, and has
reviewed the Orthodontic Entity's unaudited financial and operations statement
provided by Dr. Grove (the "Financial Statement"), a copy of which is attached
hereto as Exhibit A . Based on its review of the Orthodontic Entity and the
Financial Statement, OMEGA has issued the report (the "Report"), a copy of which
has been furnished to the Orthodontic Entity. The Orthodontic Entity and Dr.
Grove have reviewed the Report and OMEGA's literature, and agree with the Report
and the concepts of OMEGA's Exceptional Practice.

      F. Subject to the terms and conditions of this Agreement, OMEGA and Dr.
Grove have determined that it is in the best interests of each to effect a
merger of the Orthodontic Entity with and into Acquisition (the "Merger") as
provided in Section 2.1 hereof.

<PAGE>


and against any damages, liabilities, losses and expenses (including reasonable
counsel fees) of any kind or nature whatsoever which may be sustained or
suffered by OMEGA or Acquisition based upon a breach of any representation,
warranty or covenant made by the Orthodontic Entity or Dr. Grove in this
Agreement or in any exhibit, certificate, schedule or financial statement
delivered hereunder, or by reason of any claim, action or proceeding asserted or
instituted growing out o any matter or thing covered by such representations,
warranties or covenants. OMEGA and Acquisition may at their option recover such
indemnification claims by OMEGA or Acquisition by set-off against amounts of
principal and interest due under the Purchase Note, but shall not be required to
recover said claims in such manner and may proceed against Dr. Grove and his
transferees in liquidation at any time or times for recovery of indemnification
claims.

      9.2 Indemnification By OMEGA and Acquisition. Subject to the limitations
set forth in Section 9.3, OMEGA and Acquisition, jointly and severally, each
agrees to defend, indemnify and hold Dr. Grove harmless from and against any
damages, liabilities, losses and expenses (including reasonable counsel fees) of
any kind or nature whatsoever which may be sustained or suffered by Dr. Grove
based upon a breach of any representation, warranty or covenant made by OMEGA or

proceeding asserted or instituted growing out of any matter or thing covered by

amount and nature of the claim, and of any matter which in the opinion of the
claimant is likely to give rise to an indemnification claim. The indemnifying
party shall have the right to participate at its own expense in the defense of
any such matter or its settlement. If, in the opinion of the indemnified party,
its financial condition or business would not be impaired thereby, such party
may authorize the indemnifying party to take over the defense of such matter so
long as such defense is expeditious. Failure to give notice of a matter which
may give rise to an indemnification claim shall not affect the rights of any
party to collect such claim from the other party or its transferees in
liquidation.

      9.5 Payment of Claims; Alternative Dispute Resolution. Indemnification
claims by OMEGA or Acquisition may be paid or otherwise satisfied as an offset

to the public other than as a result of such party's violation of this
Agreement, (ii) became available to such party from a source other than the
other party if that source was not bound by a confidentiality agreement with

                                      -8-
<PAGE>

Churosh is likely to result in the restraint or prohibition of the consummation

     9.1 Indemnification By Dr. Churosh. Subject to the limitations set forth in
Section 9.3, Dr. Churosh agrees to defend, indemnify and hold OMEGA harmless
from and against any damages, liabilities, losses and expenses (including
reasonable counsel fees) of any kind or nature whatsoever which may be sustained
or suffered by OMEGA based upon a breach of any representation, warranty or
covenant made by the Orthodontic Entity or Dr. Churosh in this Agreement or in
any exhibit, certificate, schedule or financial statement delivered hereunder,
or by reason of any claim, action or proceeding asserted or instituted growing
out of any matter or thing covered by such representations, warranties or
covenants. OMEGA may at their option recover such indemnification claims by
OMEGA by set-off against amounts of principal and interest due under the
Purchase Note, but shall not be required to recover said claims in such manner
and may proceed against Dr. Churosh and his transferees in liquidation at any
time or times for recovery of indemnification claims.

     9.2 Indemnification By OMEGA. Subject to the limitations set forth in
Section 9.3, OMEGA agrees to defend, indemnify and hold Dr. Churosh harmless
from and against any damages, liabilities, losses and expenses (including
reasonable counsel fees) of any kind or nature whatsoever which may be sustained
or suffered by Dr. Churosh based upon a breach of any representation, warranty
or covenant made by OMEGA in this Agreement or in any exhibit, certificate,
schedule or financial statement delivered hereunder, or by reason of any claim,
action or proceeding asserted or instituted growing out of any matter or thing
covered by such representations, warranties or covenants.

     9.3 Exclusions. Notwithstanding Sections 9.1 and 9.2:



                                      -9-
<PAGE>

     (a) no indemnification shall be payable to the extent any claim is covered
by insurance; and

     (b) no indemnification shall be payable with respect to claims asserted
more than five (5) years after the Closing.

     9.4 Notice: Defense of Claims. Prompt written notice of each claim for
indemnification hereunder shall be given to the other party, specifying the
amount and nature of the claim, and of any matter which in the opinion of the
claimant is likely to give rise to an indemnification claim. The indemnifying
party shall have the right to participate at its own expense in the defense of
any such matter or its settlement. If, in the opinion of the indemnified party,
its financial condition or business would not be impaired thereby, such party
may authorize the indemnifying party to take over the defense of such matter so
long as such defense is expeditious. Failure to give notice of a matter which
may give rise to an indemnification claim shall not affect the rights of any
party to collect such claim from the other party or its transferees in
liquidation.

     9.5 Payment of Claims; Alternative Dispute Resolution. (a) Indemnification
claims by OMEGA (or any balance thereof)] shall be paid or otherwise satisfied
Dr. Churosh, or Dr. Churosh's transferees in liquidation, within 30 days after
notice thereof is given by OMEGA. In the event Dr. Churosh indicates in a
writing delivered to OMEGA that he disputes the nature or amount of the claim,
in which event the dispute upon the election of any party hereto after said
30-day period shall be settled in accordance with Section 9.5(b).

     (b) If a dispute arises under this Agreement that cannot be resolved
informally by the parties, any party may invoke the procedures set forth in
Exhibit B hereto and the parties agree to use these procedures, except paragraph
(c) of this Section 9.5, prior to any party pursuing other available remedies.
The parties will meet and attempt in good faith to resolve any controversy or
claim arising out of or relating to this Agreement.


     (c) Notwithstanding anything in this Section 9.5 to the contrary, nothing
shall preclude any party from seeking a preliminary injunction or other
provisional relief, either prior to or during the proceeding provided for in
this section, if in its judgment such action is necessary to avoid irreparable
damage or to preserve the status quo.

                            ARTICLE X. MISCELLANEOUS.

     10.1 Termination.

      (a) At any time prior to the Closing, this Agreement may be terminated (i)
by mutual consent of the parties with the approval of their respective board of
directors or members, (ii) by either if there has been a material
misrepresentation, breach of warranty or breach of covenant by the other party
in its representations, warranties and covenants set forth herein, (iii) by
OMEGA if the conditions stated in Article VI have not been satisfied at or prior
to the Closing, or (iv) by Dr. Churosh if the conditions stated in Article VII

hereunder shall terminate without any further liability of either party to the
other, except that each party shall remain obligated in respect of the
provisions of Section 10.3 and 10.7 which shall survive any such termination.

     10.2 Survival of Warranties and Other Obligations. All representations,
warranties, agreements, covenants and obligations herein or in any schedule,
exhibit, certificate or financial statement delivered by either party to the
other party incident to the transactions contemplated hereby are material, shall
be deemed to have been relied upon by the other party and shall survive the
Closing regardless of any investigation and shall not merge in the performance
of any obligation by either party hereto.

     10.3 Fees and Expenses. Each of the parties will bear its or his own
expenses in connection with the negotiation and the consummation of the
transactions contemplated by this Agreement.

     10.4 Notices. Any notice or other communication in connection with this

     10.5 Entire Agreement. This Agreement (including all exhibits or schedules
appended to this Agreement and all documents delivered pursuant to the
provisions of this Agreement, all of which are hereby incorporated herein by
reference) together with the Management Services Agreement and the Stock
Put/Call Option and Successor Designation Agreement (including all exhibits and
schedules thereto), taken together, constitute the entire agreement between the
parties, and all promises, representations, understandings, warranties and
agreements with reference to the subject matter hereof and inducements to the
making of this Agreement relied upon by my party hereto, have been expressed
herein or therein.

     10.6 Binding Agreement, Successors. This Agreement shall be binding upon,
and shall be enforceable by and inure to the benefit of, the parties named
herein and their respective successors and assigns; provided, however, that this
Agreement may not be assigned by any of the parties without the prior written
consent of all the other parties.

     10.7 Confidentiality. As used herein, "Confidential Information" means any
information or data that a party has acquired from another party that is
confidential or not otherwise available to the public, whether oral or written,
including without limitation any analyses, computations, studies or other
documents prepared from such information or data by or for the directors,
officers, employees, agents or representatives of such party (collectively, the
"Representatives"), but excluding information or data which (i) became available
to the public other than as a result of such party's violation of this
Agreement, (ii) became available to such party from a source other than the
other party if that source was not bound by a confidentiality agreement with
such other party and such source lawfully obtained such information or data, or
(iii) is required to be disclosed by applicable law, provided that promptly
after being compelled to disclose any such information or data, the party being
so compelled shall provide prompt notice thereof to the other party so that such
other party may seek a protective order or other appropriate remedy. Each party
covenants and agrees that it and its Representatives shall keep confidential and
shall not disclose all Confidential Information, except to its Representatives
and lenders who need to know such information and agree to keep it confidential.
Each party shall be responsible for any breach of this provision by its
Representatives. In the event that the Closing does not occur, each party will
promptly return to the other all copies of such other party's Confidential
Information.

     10.8 Governing Law; Severability. This Agreement shall be deemed a contract
made under the laws of the State of Delaware and, together with the rights and
obligations of the parties hereunder, shall be construed under and governed by
the laws of such state. The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision hereof.

payment to the other party or any affiliate of the other party of any cash or
other remuneration whether directly or indirectly, overtly or covertly,
specifically for patient referrals or for recommending or arranging the
purchase, lease or order of any item or service. The Consideration to be

dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties, each acting through its representative, shall meet at a
mutually acceptable time and place within five business days after the
non-disputing party designates its representative to the other. At that meeting,
the parties shall attempt in good faith to negotiate a resolution of the
dispute, or failing that, to agree on a method for resolving the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer period of time as the parties may mutually agree, the parties have not
succeeded in negotiating a resolution of the claim or dispute or agreeing on a
dispute resolution mechanism, they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

     4. The parties will jointly appoint a mutually acceptable mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above, then the parties shall select a neutral third party from
the Center for Public Resources, New York, New York ("CPR") Panels of Neutrals,
with the assistance of CPR, unless the parties agree otherwise in finding a
mutually acceptable mediator.

     5. The New PC and the MSO shall each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR.

     6. The parties agree to participate in good faith in the mediation and
negotiations related thereto for a period of thirty (30) days from appointment
of a mediator by any of the parties or the CPR.


B.   Mediation procedures

     1. The mediator shall be neutral and impartial.

     2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.

          (a)  The mediator is free to meet and communicate separately with each
               party.

          (b)  The mediator will decide when to hold joint meetings with the
               parties and when to hold separate meetings. There shall be no
               stenographic record of any meeting. Formal rules of evidence will
               not apply.

          (c)  The mediator may request that there be no direct communication
               between the parties or between their attorneys without the
               concurrence of the mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its officers and an attorney. Each party will have a representative fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator will not transmit information received from any party to
another party or any third person unless authorized to do so by the party
transmitting the information.

     6. The entire process is confidential. The parties and the mediator will
not disclose information regarding the process, including settlement terms, to
third persons, unless the parties otherwise agree. The process shall be treated
as a compromise negotiation for purposes of the Federal Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing administrative and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

          (a)  The mediator will be disqualified as a witness, consultant or
               expert in any pending or future investigation, action or
               proceeding relating to the subject matter of the mediation
               (including any investigation, action or proceeding which involves
               persons not party to this mediation); and

          (b)  The mediator and any documents and information in the mediator's
               possession will not be subpoenaed in any such investigation,
               action or proceeding, and all parties will oppose any effort to
               have the mediator and documents subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.

     10. The mediator, if a lawyer, may freely express views to the parties on
the legal issues of the dispute.


                                      -17-

     11. The mediator shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons, (ii) if the mediator believes that a party
is not acting in good faith, or (iii) if the mediator concludes that further
mediation efforts would not be useful.

C.   Binding Arbitration

     If the parties do not resolve the dispute through mediation within the
period provided in Part A above, the parties shall submit the matter to binding
arbitration in Boston, Massachusetts before a qualified sole arbitrator in
accordance with the then current CPR Rules for Non-Administered Arbitration of
Business Disputes. If the party initially raising the dispute to be resolved is
New PC or Dr. Churosh, the arbitration shall be held in Boston, Massachusetts,
and if the party initially raising the dispute to be resolved is the MSO or
OMEGA, the arbitration shall be held in Goodyear, Arizona. The sole arbitrator
shall be agreed upon by the parties within twenty (20) days after either party
elects to submit any issue to arbitration or, failing that, shall be selected by
CPR. A qualified arbitrator is one who is familiar with the principal subject
matter of the issues to be arbitrated such as by way of example, healthcare
services industry matters, management consulting services generally or business
law/corporate matters generally. Judgment upon the award rendered by the
arbitrator may be entered in any court having jurisdiction. The arbitrator shall
not have the authority to award multiple, punitive or consequential damages
under any circumstances.

     THIS AFFILIATION AGREEMENT AND AGREEMENT AND PLAN OF MERGER is entered into
as of the ___ day of ___________ 1997, by and among Omega Orthodontics, Inc., a
Delaware corporation ("OMEGA" or "Surviving Entity"); Clark E. Schneekluth,

state of California (the "State"); and Clark E. Schneekluth, D.D.S., P.C., a
California professional corporation (the "Orthodontic Entity").

                                    RECITALS

     A. OMEGA provides professional management and marketing services to
orthodontic practices in the United States, which services include providing

public through the services of Dr. Schneekluth affiliated with the Orthodontic
Entity.

     C. Dr. Schneekluth presently holds 100% of the issued and outstanding
capital stock of the Orthodontic Entity (the issued and outstanding capital

hereto as Exhibit A . Based on its review of the Orthodontic Entity and the
Financial Statement, OMEGA has issued the report (the "Report"), a copy of which

Report and the concepts of OMEGA's Exceptional Practice.

and which incurred since the date of the Financial Statement in the ordinary
course of business.

     6.8 Due Diligence. OMEGA, acting in good faith and in its sole discretion,
shall be reasonably satisfied with the results of its "Due Diligence" on Dr.

business of the Orthodontic Entity from the information provided prior to the

consummation of any material transaction contemplated hereby.

                    ARTICLE VIII. OBLIGATIONS AFTER CLOSING.

     8.1 OMEGA Exceptional Practice and the Report Suggestions. On and after the

     8.2 Books and Records. OMEGA shall permit Dr. Schneekluth, his accountants

license.

                          ARTICLE IX. INDEMNIFICATION.

     9.1 Indemnification By Dr. Schneekluth. Subject to the limitations set
forth in Section 9.3, Dr. Schneekluth agrees to defend, indemnify and hold OMEGA
harmless from and against any damages, liabilities, losses and expenses
(including reasonable counsel fees) of any kind or nature whatsoever which may
be sustained or suffered by OMEGA based upon a breach of any representation,
warranty or covenant made by the Orthodontic Entity or Dr. Schneekluth in this
Agreement or in any exhibit, certificate, schedule or financial statement
delivered hereunder, or by reason of any claim, action or proceeding asserted or
instituted growing out of any matter or thing covered by such representations,
warranties or covenants. OMEGA may at their option recover such indemnification
claims by OMEGA by set-off against amounts of principal and interest due under
the Purchase Note, but shall not be required to recover said claims in such
manner and may proceed against Dr. Schneekluth and his transferees in
liquidation at any time or times for recovery of indemnification claims.


                                      -8-
<PAGE>

     9.2 Indemnification By OMEGA. Subject to the limitations set forth in
Section 9.3, OMEGA agrees to defend, indemnify and hold Dr. Schneekluth harmless
from and against any damages, liabilities, losses and expenses (including
reasonable counsel fees) of any kind or nature whatsoever which may be sustained
or suffered by Dr. Schneekluth based upon a breach of any representation,
warranty or covenant made by OMEGA in this Agreement or in any exhibit,
certificate, schedule or financial statement delivered hereunder, or by reason
of any claim, action or proceeding asserted or instituted growing out of any
matter or thing covered by such representations, warranties or covenants.

     9.3 Exclusions. Notwithstanding Sections 9.1 and 9.2:

     (a) no indemnification shall be payable to the extent any claim is covered
by insurance; and

     (b) no indemnification shall be payable with respect to claims asserted
more than five (5) years after the Closing.

     9.4 Notice: Defense of Claims. Prompt written notice of each claim for
indemnification hereunder shall be given to the other party, specifying the
amount and nature of the claim, and of any matter which in the opinion of the
claimant is likely to give rise to an indemnification claim. The indemnifying
party shall have the right to participate at its own expense in the defense of
any such matter or its settlement. If, in the opinion of the indemnified party,
its financial condition or business would not be impaired thereby, such party
may authorize the indemnifying party to take over the defense of such matter so
long as such defense is expeditious. Failure to give notice of a matter which
may give rise to an indemnification claim shall not affect the rights of any
party to collect such claim from the other party or its transferees in
liquidation.

     9.5 Payment of Claims; Alternative Dispute Resolution. (a) Indemnification
claims by OMEGA may be paid or otherwise satisfied as an offset against the
Purchase Note as set forth under Section 9.1, and, in the alternative or after
any such offset, the indemnification claims (or any balance thereof) shall be
paid or otherwise satisfied Dr. Schneekluth, or Dr. Schneekluth's transferees in
liquidation, within 30 days after notice thereof is given by OMEGA. In the event
Dr. Schneekluth indicates in a writing delivered to OMEGA that he disputes the
nature or amount of the claim, in which event the dispute upon the election of
any party hereto after said 30-day period shall be settled in accordance with
Section 9.5(b).

     (b) If a dispute arises under this Agreement that cannot be resolved
informally by the parties, any party may invoke the procedures set forth in
Exhibit F hereto and the parties agree to use these procedures, except paragraph
(c) of this Section 9.5, prior to any party pursuing other available remedies.
The parties will meet and attempt in good faith to resolve any controversy or
claim arising out of or relating to this Agreement.



                                      -9-
<PAGE>

     (c) Notwithstanding anything in this Section 9.5 to the contrary, nothing
shall preclude any party from seeking a preliminary injunction or other
provisional relief, either prior to or during the proceeding provided for in
this section, if in its judgment such action is necessary to avoid irreparable
damage or to preserve the status quo.


                            ARTICLE X. MISCELLANEOUS.

     10.1 Termination.

     (a) At any time prior to the Closing, this Agreement may be terminated (i)

Agreement, this Agreement may be terminated by OMEGA or Dr. Schneekluth upon

to the other, except that each party shall remain obligated in respect of the
provisions of Section 10.3 and 10.7 which shall survive any such termination.

         10.2 Survival of Warranties and Other Obligations. All representations,
warranties, agreements, covenants and obligations herein or in any schedule,
exhibit, certificate or financial statement delivered by either party to the
other party incident to the transactions contemplated hereby are material, shall
be deemed to have been relied upon by the other party and shall survive the
Closing regardless of any investigation and shall not merge in the performance
of any obligation by either party hereto.

         10.3 Fees and Expenses. Each of the parties will bear its or his own
expenses in connection with the negotiation and the consummation of the
transactions contemplated by this Agreement.

Agreement shall be deemed to be delivered if in writing (or in the form of a

delivery thereof.

     10.5 Entire Agreement. This Agreement (including all exhibits or schedules
appended to this Agreement and all documents delivered pursuant to the
provisions of this Agreement, all of which are hereby incorporated herein by
reference) together with the Management Services Agreement and the Stock
Put/Call Option and Successor Designation Agreement (including all exhibits and
schedules thereto), taken together, constitute the entire agreement between the
parties, and all promises, representations, understandings, warranties and
agreements with reference to the subject matter hereof and inducements to the
making of this Agreement relied upon by my party hereto, have been expressed
herein or therein.

     10.6 Binding Agreement, Successors. This Agreement shall be binding upon,
and shall be enforceable by and inure to the benefit of, the parties named
herein and their respective successors and assigns; provided, however, that this
Agreement may not be assigned by any of the parties without the prior written
consent of all the other parties.

     10.7 Confidentiality. As used herein, "Confidential Information" means any
information or data that a party has acquired from another party that is
confidential or not otherwise available to the public, whether oral or written,
including without limitation any analyses, computations, studies or other
documents prepared from such information or data by or for the directors,
officers, employees, agents or representatives of such party (collectively, the
"Representatives"), but excluding information or data which (i) became available
to the public other than as a result of such party's violation of this
Agreement, (ii) became available to such party from a source other than the
other party if that source was not bound by a confidentiality agreement with
such other party and such source lawfully obtained such information or data, or
(iii) is required to be disclosed by applicable law, provided that promptly
after being compelled to disclose any such information or data, the party being
so compelled shall provide prompt notice thereof to the other party so that such
other party may seek a protective order or other appropriate remedy. Each party
covenants and agrees that it and its Representatives shall keep confidential and
shall not disclose all Confidential Information, except to its Representatives
and lenders who need to know such information and agree to keep it confidential.
Each party shall be responsible for any breach of this provision by its
Representatives. In the event that the Closing does not occur, each party 




                                      -11-
<PAGE>

will promptly return to the other all copies of such other party's Confidential

     10.8 Governing Law; Severability. This Agreement shall be deemed a contract
made under the laws of the State of Delaware and, together with the rights and
obligations of the parties hereunder, shall be construed under and governed by
the laws of such state. The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision hereof.

     10.9 Referrals. Nothing in this Agreement shall be construed as an offer or
payment to the other party or any affiliate of the other party of any cash or
other remuneration whether directly or indirectly, overtly or covertly,
specifically for patient referrals or for recommending or arranging the
purchase, lease or order of any item or service. The Consideration to be
received upon consummation of the Merger represents the fair market value of the
Orthodontic Entity and is not in any way related to or dependent upon referrals
by and between OMEGA, Acquisition and Dr. Schneekluth.

     10.10 Further Assurances. Following the execution of this Agreement, Dr.
Schneekluth, the Orthodontic Entity and OMEGA each agrees:

Agreement, and the transactions contemplated herein;

     (b) to confer on a regular basis with the other, report on material
operational matters and promptly advise the other orally or in writing of any
change or event resulting in or which, insofar as can reasonably be foreseen
could result in, a material adverse effect on such party or which would cause or
constitute a material breach of any of the representations, warranties or
covenants of such party contained herein; and

     (c) to provide the other (or its counsel) promptly with copies of all
filings made by such party with any state or federal governmental entity in
connection with this Agreement or the transactions contemplated hereby.

                                    ---------

                   ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A.   Method of Invoking ADR Procedures

     1. These procedures may be invoked by any party to an agreement which
incorporates these procedures by giving written notice to the other of the
dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties, each acting through its representative, shall meet at a
mutually acceptable time and place within five business days after the
non-disputing party designates its representative to the other. At that meeting,
the parties shall attempt in good faith to negotiate a resolution of the
dispute, or failing that, to agree on a method for resolving the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer period of time as the parties may mutually agree, the parties have not
succeeded in negotiating a resolution of the claim or dispute or agreeing on a
dispute resolution mechanism, they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

     4. The parties will jointly appoint a mutually acceptable mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above, then the parties shall select a neutral third party from
the Center for Public Resources, New York, New York ("CPR") Panels of Neutrals,
with the assistance of CPR, unless the parties agree otherwise in finding a
mutually acceptable mediator.

     5. The New PC and the MSO shall each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR.

     6. The parties agree to participate in good faith in the mediation and
negotiations related thereto for a period of thirty (30) days from appointment
of a mediator by any of the parties or the CPR.


B.   Mediation procedures

     1. The mediator shall be neutral and impartial.



                                      -19-
<PAGE>

     2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.


     (a)  The mediator is free to meet and communicate separately with each
          party.

     (b)  The mediator will decide when to hold joint meetings with the parties
          and when to hold separate meetings. There shall be no stenographic
          record of any meeting. Formal rules of evidence will not apply.

     (c)  The mediator may request that there be no direct communication between
          the parties or between their attorneys without the concurrence of the
          mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its officers and an attorney. Each party will have a representative fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator will not transmit information received from any party to
another party or any third person unless authorized to do so by the party
transmitting the information.

     6. The entire process is confidential. The parties and the mediator will
not disclose information regarding the process, including settlement terms, to
third persons, unless the parties otherwise agree. The process shall be treated
as a compromise negotiation for purposes of the Federal Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing administrative and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

     (a)  The mediator will be disqualified as a witness, consultant or expert
          in any pending or future investigation, action or proceeding relating
          to the subject matter of the mediation (including any investigation,
          action or proceeding which involves persons not party to this
          mediation); and

     (b)  The mediator and any documents and information in the mediator's
          possession will not be subpoenaed in any such investigation, action or
          proceeding, and all parties will oppose any effort to have the
          mediator and documents subpoenaed.

                                      -20-

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.

     10. The mediator, if a lawyer, may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons, (ii) if the mediator believes that a party
is not acting in good faith, or (iii) if the mediator concludes that further
mediation efforts would not be useful.

C.   Binding Arbitration

     If the parties do not resolve the dispute through mediation within the
period provided in Part A above, the parties shall submit the matter to binding
arbitration in Boston, Massachusetts before a qualified sole arbitrator in
accordance with the then current CPR Rules for Non-Administered Arbitration of
Business Disputes. If the party initially raising the dispute to be resolved is
New PC or Dr. Schneekluth, the arbitration shall be held in Boston,
Massachusetts, and if the party initially raising the dispute to be resolved is
OMEGA, the arbitration shall be held in Huntington Beach, California. The sole
arbitrator shall be agreed upon by the parties within twenty (20) days after
either party elects to submit any issue to arbitration or, failing that, shall
be selected by CPR. A qualified arbitrator is one who is familiar with the
principal subject matter of the issues to be arbitrated such as by way of
example, healthcare services industry matters, management consulting services
generally or business law/corporate matters generally. Judgment upon the award
rendered by the arbitrator may be entered in any court having jurisdiction. The
arbitrator shall not have the authority to award multiple, punitive or
consequential damages under any circumstances.

      and, if redeemable, the price, terms and manner of redemption;

            (d) the preferences,  if any, and the special and relative rights of

      operation  of a  sinking  or  purchase  fund  and,  if so,  the  terms and
      provisions of such fund;

            (f)  whether or not the shares of such series  shall be  convertible
      into shares of any other  class or of any other  series of the same or any
      other class of stock of the Corporation  and, if so, the conversion  price
      or ratio and other conversion rights;

            (g) the conditions  under which the shares of such series shall have

      SIXTH:  No director shall be personally  liable to the  Corporation or its
stockholders  for monetary  damages for breach of fiduciary  duty as a director,
provided  that this  provision  shall not limit or eliminate  the liability of a
director (i) for any breach of the director's duty of loyalty to the Corporation
or its  stockholders,  (ii) for  acts or  omissions  not in good  faith or which

intentional misconduct or a knowing violation of law, (iii) under Section 174 of
the  General  Corporation  Law of  the  State  of  Delaware,  or  (iv)  for  any
transaction from which the director  derived an improper  personal  benefit.  If
there is any  amendment or revocation  of this  provision,  the liability of any
director for any action taken prior to the amendment or  revocation  will not be
affected  thereby.  If the General  Corporation  Law of the State of Delaware is
hereafter  amended to authorize  the further  elimination  or  limitation of the
liability of a director,  then the  liability  of a director of the  Corporation
shall be  eliminated or limited to the fullest  extent  permitted by the General
Corporation Law of the State of Delaware, as so amended.

      TWELFTH:  Whenever a compromise or  arrangement  is proposed  between this
Corporation  and  its  creditors  or any  class  of  them  and/or  between  this
Corporation  and its  stockholders  or any class of them, any court of equitable
jurisdiction  within the State of Delaware may, on the  application in a summary
way of this  Corporation  or of any  creditor or  stockholder  thereof or on the
application of any receiver or receivers  appointed for this  Corporation  under
the  provisions  of Section 291 of the General  Corporation  Law of the State of
Delaware or on the  application of trustees in dissolution or of any receiver or
receivers  appointed for this Corporation under the provisions of Section 279 of
the  General  Corporation  Law of the State of  Delaware  order a meeting of the
creditors  or  class  of  creditors,  and/or  of the  stockholders  or  class of
stockholders  of the  Corporation,  as the case may be, to be  summoned  in such
manner  as  the  said  court  directs.  If a  majority  in  number  representing
three-fourths in value of the creditors,  and/or of the stockholders or class of
stockholders of this Corporation, as the case may be, agree to any compromise or
arrangement and to any reorganization of this Corporation as consequence of such
compromise  or  arrangement,  the said  compromise or  arrangement  and the said
reorganization  shall, if sanctioned by the court to which the said  application
has been made, be binding on all the creditors or class of creditors,  and/or on
all of the stockholders or class of stockholders,  of this  Corporation,  as the
case may be, and also on this Corporation.

hereafter in effect,  indemnify any and all persons whom it shall have the power
to indemnify  under said  Section from and against any and all of the  expenses,
liabilities or other matters referred to in or covered by said Section,  and the
indemnification  provided for herein shall not be deemed  exclusive of any other
rights  to  which a  person  indemnified  may be  entitled  under  any  by-laws,
agreement, vote of stockholders or disinterested directors or otherwise, both as
to action in his or her official  capacity and as to action in another  capacity
while holding such office,  and shall  continue as to a person who has ceased to
be a director,  officer, employee or agent and shall inure to the benefit of the
heirs,  executors and administrators of such a person. No amendment or repeal of
this provisions shall preclude the Corporation  from providing  indemnity to any
person on account of any acts or omissions  occurring prior to such amendment or
repeal.

     Section 2. Any of or all the signatures on a certificate may be facsimile.
In case any officer, transfer agent or registrar who has signed or whose
facsimile signature has been placed upon a certificate shall have ceased to be
such officer, transfer agent or registrar before such certificate is issued, it
may be issued by the corporation with the same effect as if such officer,
transfer agent or registrar were such officer, transfer agent or registrar at
the date of issue.

                                LOST CERTIFICATES

     Section 3. The board of directors may direct a new certificate or
certificates or uncertificated shares to be issued in place of any certificate
or certificates theretofore issued by the corporation alleged to have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming the certificate of stock to be lost, stolen or destroyed. When
authorizing such issue of a new certificate or certificates or uncertificated
shares, the board of directors may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed certificate or certificates, or such owner's legal representative, to
advertise the same in such manner as it shall require and/or to give the
corporation a bond in such sum as it may direct as indemnity against any claim
that may be made against the corporation with respect to the certificate alleged
to have been lost, stolen or destroyed.

                                TRANSFER OF STOCK

     Section 4. Upon surrender to the corporation or the transfer agent of the
corporation of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignation or authority to transfer, it shall be the
duty of the corporation to issue a new certificate to the person entitled
thereto, cancel the old certificate and record the transaction upon its books.
Upon receipt of proper transfer instructions from the registered owner of
uncertificated shares such uncertificated shares shall be canceled and issuance
of new equivalent uncertificated shares or certificated shares shall be made to
the person entitled thereto and the transaction shall be recorded upon the books
of the corporation.

                               FIXING RECORD DATE

     Section 5. In order that the corporation may determine the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or


                                       9
<PAGE>


other distribution or allotment of any rights, or entitled to exercise any
rights in respect of any change, conversion or exchange of stock or for the
purpose of any other lawful action, the board of directors may fix, in advance,
a record date, which shall not be more than sixty nor less than ten days before
the date of such meeting, nor more than sixty days prior to any other action. A
determination of stockholders of record entitled to notice of or to vote at a
meeting of stockholders shall apply to any adjournment of the meeting: provided,
however, that the board of directors may fix a new record date for the adjourned
meeting.

                             REGISTERED STOCKHOLDERS

     Section 6. The corporation shall be entitled to recognize the exclusive
right of a person registered on its books as the owner of shares to receive
dividends, and to vote as such owner, and to hold liable for calls and
assessments a person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such
share or shares on the part of any other person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

to, each Covered Person who is, was or is threatened to be made a party or is
otherwise involved in any Proceeding, as provided in this Article and to the
fullest extent permitted by applicable law in effect on the date hereof and to
such greater extent as applicable law may hereafter from time to time permit.

     The indemnification provisions in this Article shall be deemed to be a
contract between the corporation and each Covered Person who serves in any
Corporate Status at any time while these provisions as well as the relevant
provisions of the Delaware General Corporation Law are in effect, and any repeal
or modification thereof shall not affect any right or obligation then existing
with respect to any state of facts then or previously existing or any Proceeding

any such state of facts. Such a contract right may not be modified retroactively
without the consent of such Covered Person.

     (b) Employees, Consultants and Agents. The corporation may, to the extent

Section 9 if, by reason of such Covered Person's Corporate Status, such Covered
Person is, or is threatened to be made, a party to or is otherwise involved in
any Proceeding brought by or in the right of the corporation to procure a
judgment in its favor. Such Covered Person shall be indemnified against
Expenses, judgments, penalties, fines and amounts paid in settlement, actually
and reasonably incurred by such Covered Person or on such Covered Person's
behalf in connection with such Proceeding or any claim, issue or matter therein,
if such Covered Person acted in Good Faith. Notwithstanding 


                                       13
<PAGE>


the foregoing, no such indemnification shall be made in respect of any claim,
issue or matter in such Proceeding as to which such Covered Person shall have
been adjudged to be liable to the corporation if applicable law prohibits such
indemnification; provided, however, that, if applicable law so permits,
indemnification shall nevertheless be made by the corporation in such event if
and only to the extent that the Court which is considering the matter shall so
determine.

     Section 10. Indemnification of a Party Who is Wholly or Partly Successful.
Notwithstanding any other provision of this Article, to the extent that a
Covered Person is, by reason of such Covered Person's Corporate Status, a party
to or is otherwise involved in and is successful, on the merits or otherwise, in
any Proceeding, such Covered Person shall be indemnified to the maximum extent
permitted by law, against all Expenses, judgments, penalties, fines, and amounts
paid in settlement, actually and reasonably incurred by such Covered Person or
on such Covered Person's behalf in connection therewith. If such Covered Person
is not wholly successful in such Proceeding but is successful, on the merits or
otherwise, as to one or more but less than all claims, issues or matters in such
Proceeding, the corporation shall indemnify such Covered Person to the maximum
extent permitted by law, against all Expenses, judgments, penalties, fines, and
amounts paid in settlement, actually and reasonably incurred by such Covered
Person or on such Covered Person's behalf in connection with each successfully
resolved claim, issue or matter. For purposes of this Section 10 and without
limitation, the termination of any claim, issue or matter in such a Proceeding
by dismissal, with or without prejudice, shall be deemed to be a successful
result as to such claim, issue or matter.

     Section 11. Indemnification for Expenses of a Witness. Notwithstanding any
other provision of this Article, to the extent that a Covered Person is, by
reason of such Covered Person's Corporate Status, a witness in any Proceeding,
such Covered Person shall be indemnified against all Expenses actually and
reasonably incurred by such Covered Person or on such Covered Person's behalf in
connection therewith.

     Section 12. Advancement of Expenses. Notwithstanding any provision to the
contrary in this Article, the corporation shall advance all reasonable Expenses
which, by reason of a Covered Person's Corporate Status, were incurred by or on
behalf of such Covered Person in connection with any Proceeding, within twenty
(20) days after the receipt by the corporation of a statement or statements from
such Covered Person requesting such advance or advances, whether prior to or
after final disposition of such Proceeding. Such statement or statements shall
reasonably evidence the Expenses incurred by the Covered Person and shall
include or be preceded or accompanied by an undertaking by or on behalf of the
Covered Person to repay any Expenses if such Covered Person shall be adjudged to
be not entitled to be indemnified against such Expenses. Any advance and
undertakings to repay made pursuant to this Section 12 shall be unsecured and
interest-free. Advancement of Expenses pursuant to this Section 12 shall not
require approval of the board of directors or the stockholders of the
corporation, or of any other person or body. The secretary of the corporation
shall promptly advise the Board in writing of the request for advancement of
Expenses, of the amount and other details of the advance and of the undertaking
to make repayment provided pursuant to this Section 12.

     Section 13. Notification and Defense of Claim. Promptly after receipt by a
Covered


                                       14
<PAGE>


Person of notice of the commencement of any Proceeding, such Covered Person
shall, if a claim is to be made against the corporation under this Article,
notify the corporation of the commencement of the Proceeding. The omission of
such notice will not relieve the corporation from any liability which it may
have to such Covered Person otherwise than under this Article. With respect to
any such Proceedings of which such Covered Person has provided notice to the
corporation:

     (a) The corporation will be entitled to participate in the defense at its
own expense.

     (b) Except as otherwise provided below, the corporation (jointly with any
other indemnifying party similarly notified) will be entitled to assume the
defense with counsel reasonably satisfactory to the Covered Person. After notice
from the corporation to the Covered Person of its election to assume the defense
of a suit, the corporation will not be liable to the Covered Person under this
Article for any legal or other expenses subsequently incurred by the Covered
Person in connection with the defense of the Proceeding other than reasonable
costs of investigation or as otherwise provided below.

     The Covered Person shall have the right to employ his own counsel in such
Proceeding but the fees and expenses of such counsel incurred after notice from
the corporation of its assumption of the defense shall be at the expense of the
Covered Person except as follows. The fees and expenses of counsel shall be at
the expense of the corporation if (i) the employment of counsel by the Covered
Person has been authorized by the corporation, (ii) the Covered Person shall
have concluded reasonably that there may be a conflict of interest between the
corporation and the Covered Person in the conduct of the defense of such action
and such conclusion is confirmed in writing by the corporation's outside counsel
regularly employed by it in connection with corporate matters, or (iii) the
corporation shall not in fact have employed counsel to assume the defense of
such Proceeding. The corporation shall be entitled to participate in, but shall
not be entitled to assume the defense of, any Proceeding brought by or in the
right of the corporation or as to which the Covered Person shall have made the
conclusion provided for in (ii) above and such conclusion shall have been so
confirmed by the corporation's said outside counsel.

        (c) Notwithstanding any provision of this Article to the contrary, the
corporation shall not be liable to indemnify the Covered Person under this
Article for any amounts paid in settlement of any Proceeding effected without
its written consent. The corporation shall not settle any Proceeding or claim in
any manner which would impose any penalty, limitation or disqualification of the
Covered Person for any purpose without such Covered Person's written consent.
Neither the corporation nor the Covered Person will unreasonably withhold their
consent to any proposed settlement.

     (d) If it is determined that the Covered Person is entitled to
indemnification other than as afforded under subparagraph (b) above, payment to
the Covered Person of the additional amounts for which the Covered Person is to
be indemnified shall be made within ten (l0) days after such determination.

     Section 14. Procedures.

                                       15
<PAGE>


     (a) Method of Determination. A determination (as provided for by this
Article or if required by applicable law in the specific case) with respect to a
Covered Person's entitlement to indemnification shall be made either (a) by the
board of directors by a majority vote of a quorum consisting of Disinterested
directors, or (b) in the event that a quorum of the board of directors
consisting of Disinterested directors is not obtainable or, even if obtainable,
such quorum of Disinterested directors so directs, by Independent Counsel in a
written determination to the board of directors, a copy of which shall be
delivered to the Covered Person seeking indemnification, or (c) by the vote of
the holders of a majority of the corporation's capital stock outstanding at the
time entitled to vote thereon.

     (b) Initiating Request. A Covered Person who seeks indemnification under
this Article shall submit a Request for Indemnification, including such
documentation and information as is reasonably available to such Covered Person
and is reasonably necessary to determine whether and to what extent such Covered
Person is entitled to indemnification.

     (c) Presumptions. In making a determination with respect to entitlement to
indemnification hereunder, the person or persons or entity making such
determination shall presume that the Covered Person is entitled to
indemnification under this Article.

     (d) Burden of Proof. The person or entity opposing a Covered Person's claim
for indemnification shall have the burden of proof to overcome the presumption
described by Section 14(c) above in connection with the making by any person,
persons or entity of any determination contrary to that presumption.

     (e) Effect of Other Proceedings. The termination of any proceeding or of
any claim, issue or matter therein, by judgment, order, settlement of
conviction, or upon a plea of guilty or of nolo contendere or its equivalent,
shall not (except as otherwise expressly provided in this Article) of itself
adversely affect the right of a Covered Person to indemnification or create a
presumption that a Covered Person did not act in Good Faith.

     Section 15. Action by the Corporation. Any action, payment, advance
determination other than a determination made pursuant to Section 14,
authorization, requirement, grant of indemnification or other action taken by
the corporation pursuant to this Article shall be effected exclusively through
any Disinterested person so authorized by the board of directors of the
corporation, including the president or any vice president of the corporation.

     Section l6. Non-Exclusivity. The rights to indemnification and to receive
advancement of Expenses as provided by this Article shall not be deemed
exclusive of any other rights to which a Covered Person may at any time be
entitled under applicable law, the certificate of incorporation, these by-laws,
any agreement, a vote of stockholders, a resolution of the board of directors,
or otherwise. No amendment, alteration, rescission or replacement of this
Article or any provision hereof shall be effective as to a Covered Person with
respect to any action taken or omitted by such Covered Person in such Covered
Person's Corporate Status or with respect to any state of facts then or
previously existing or any Proceeding previously or thereafter brought or
threatened based in whole or to the extent based in part upon any such state of
facts existing


                                       16
<PAGE>


prior to such amendment, alteration, rescission or replacement.

     Section l7. Insurance. The corporation may maintain, at its expense, an
insurance policy or policies to protect itself and any Covered Person, officer,
employee or agent of the corporation or another enterprise against liability
arising out of this Article or otherwise, whether or not the corporation would
have the power to indemnify any such person against such liability under the
Delaware General Corporation Law.

     Section l8. No Duplicative Payment. The corporation shall not be liable
under this Article to make any payment of amounts otherwise indemnifiable
hereunder if and to the extent that a Covered Person has otherwise actually
received such payment under any insurance policy, contract, agreement or
otherwise.

     Section 19. Expenses of Adjudication. In the event that any Covered Person
seeks a judicial adjudication, or an award in arbitration, to enforce such
Covered Person's rights under, or to recover damages for breach of, this
Article, the Covered Person shall be entitled to recover from the corporation,
and shall be indemnified by the corporation against, any and all expenses (of
the types described in the definition of Expenses in Section 6 actually and
reasonably incurred by such Covered Person in seeking such adjudication or
arbitration, but only if such Covered Person prevails therein. If it shall be
determined in such adjudication or arbitration that the Covered Person is
entitled to receive part but not all of the indemnification of expenses sought,
the expenses incurred by such Covered Person in connection with such
adjudication or arbitration shall be appropriately prorated.

     Section 20. Severability. If any provision or provisions of this Article
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:

     (a) the validity, legality and enforceability of the remaining provisions
of this Article (including without limitation, each portion of any Section of
this Article containing any such provision held to be invalid, illegal or
unenforceable, that is not itself invalid, illegal or unenforceable) shall not
in any way be affected or impaired thereby; and

     (b) to the fullest extent possible, the provisions of this Article
(including, without limitation, each portion of any Section of this Article
containing any such provision held to be invalid, illegal or unenforceable, that
is not itself held to be invalid, illegal or unenforceable) shall be construed
so as to give effect to the intent manifested by the provision held invalid, is
conferred upon the board of directors by the certificate of incorporation it

B.   Sale or Transfer of Shares; Legend

     (a) The Shares and the Registerable Shares and shares issued in respect of
the Shares or the Registrable Shares shall not be sold or transferred unless
either (i) they first shall have been registered under the Securities Act, or

counsel, reasonably satisfactory to the Company, to the effect that such sale or
transfer is exempt from the registration requirements of the Securities Act.

     (b) Each certificate representing the Shares and the Registrable Shares,
and shares issued in respect of the Shares and the Registrable Shares, shall

     "The shares represented by this certificate have not been registered under
     the Securities Act of 1933, as amended, and may not be offered, sold or

     registered under such Act or an opinion of counsel reasonably satisfactory
     to the Company is obtained to the effect that such registration is not
     required."

     The foregoing legend shall be removed from the certificates representing
any Registrable Shares, at the request of the holder thereof, at such time as
they become eligible for resale pursuant to Rule 144(k) under the Securities
Act.

C.   Registration Rights

     1. Incidental Registration Rights. (a) If the Company at any time proposes
for any reason to register any of its securities under the Act (other than in
connection with its Initial Public Offering or pursuant to a registration
statement on Forms S-4, S-8 or similar or successor or another form which is not
available for registering Registrable Securities for sale to the public), it
shall each such time promptly give written notice to all Holders of Registrable
Securities of its intention so to do, and, upon the written request, given
within 10 days after receipt of any such notice, of such Holder to register any
Registrable Securities, which request shall specify the number of Registrable
Securities intended to be sold or disposed of by such Holders and shall state
the intended method of disposition of such Registrable Securities by such
Holders, the Company shall use its best efforts to cause all such Registrable
Securities to 



<PAGE>

be registered under the Act as required to permit the sale or other disposition
(in accordance with the intended methods thereof, as aforesaid) by such Holders.
Notwithstanding the foregoing, the Company shall have the right to withdraw such
registration statement, if so required by prudent business judgment, provided it
shall reimburse the persons who indicated their intention to include Registrable
Securities therein for the out-of-pocket expenses reasonably incurred by such
persons in connection therewith. "Registrable Securities", for purposes of this
Section 6(c), means (i) the Shares and (ii) any shares of Common Stock issued as
(or issuable upon the conversion or exercise of any warrant, right or other
security which is issued as) a dividend or other distribution with respect to,
or in exchange for, or in replacement of, any of such Shares.

     (b) In the event that the proposed registration by the Company is, in whole
or in part, an underwritten public offering of securities of the Company (other
than the Initial Public Offering as to which the Holder shall have no
registration rights under this Section 6(c)), any request pursuant to this
Section 6 to register may specify that the Registrable Securities are to be
included in the underwriting (i) on the same terms and conditions as the shares
of Common Stock, if any, otherwise being sold through underwriters under such
registration or (ii) on terms and conditions comparable to those normally
applicable to offerings of common stock in reasonably similar circumstances in
the event that no shares of Common Stock other than Registrable Securities are
being sold through underwriters under such registration; provided, however, that
if the managing underwriter determines and advises in writing that the inclusion
of all Registrable Securities proposed to be included in the underwritten public
offering and other issued and outstanding shares of Common Stock proposed to be
included therein by persons other than holders of Registrable Securities (the
"Other Shares") would interfere with the successful marketing of such
securities, then the number of Registrable Securities and Other Shares shall be
reduced pro rata among the holders of Registrable Securities and Other Shares,
as necessary.

     2. Demand Registration. At any time after the Company becomes eligible to
file a Registration Statement on Form S-3 (or any successor form relating to
secondary offerings), a Holder holding in the aggregate at least 25% of the
Registrable Shares may request the Company, in writing, to effect the
registration on Form S-3 (or such successor form). Upon receipt of any such
request, the Company shall promptly give written notice of such proposed
registration to all Holders. Such Holders shall have the right by giving written
notice to the Company within 30 days after the Company provides its notice, to
elect to have included in such registration such of their Registrable Shares as
such Holders may request in such notice of Election. Thereupon, the Company
shall, as expeditiously as possible, use its best efforts to effect the
registration on Form S-3, or such successor form, of all Registrable Shares
which the Company has been requested to register.

     3. Preparation and Filing. If and whenever the Company is under an
obligation pursuant to the provisions of this Section 6(c) to use its best
efforts to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as practicable:

     (a) prepare and file with the SEC a registration statement with respect to
such securities and use its best efforts to cause such registration statement to
become and remain effective;


<PAGE>

     (b) prepare and file with the SEC such amendments and supplements to such
registration statements and the prospectus used in connection therewith as may
be necessary to keep such registration statement effective for at least nine
months and to comply with the provisions of the Securities Act with respect to
the sale or other disposition of all Registrable Securities covered by such
registration statement;

     (c) furnish to each seller such number of copies of a summary prospectus or
other prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as such seller may
reasonably request in order to facilitate the public sale or other disposition
of such Registrable Securities;

     (d) use its best efforts to register or qualify the Registrable Securities
covered by such registration statement under the securities or blue sky laws of
such jurisdictions as each such seller shall reasonably request (provided,
however, that the Company shall not be required to consent to general service of
process for all purposes or qualify to do business in any jurisdiction where it
is not then qualified) and do any and all other acts or things which may be
reasonably necessary or advisable to enable such seller to consummate the public
sale or other disposition in such jurisdictions of such securities; and

     (e) notify each seller of Registerable Securities covered by such
registration statement at any time when a prospectus relating thereto covered by
such registration statement is required to be delivered under the Securities Act
within the appropriate period mentioned in clause (b) of this ss.8.3, of the
happening of any event as a result of which the prospectus included in such
registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the
circumstances then existing, and at the request of such seller, prepare and
furnish to such seller a reasonable number of copies of a supplement to or an
amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such securities, such prospectus shall not
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances then existing.

     4. Registration Expenses. All Registration Expenses incurred in complying
with this Section 6(c) shall be paid for by the Company.

     5. Indemnification. In the event of any registration of Registrable
Securities under the Securities Act pursuant to this Section 6(c) or other
registration or qualification thereof pursuant to Section 6(c)(3)(d) hereof, the
Company shall enter into an indemnity agreement with the sellers of Registrable
Securities in customary form relating thereto.

     6. Assignment. The rights to cause the Company to register Registrable
Securities pursuant to this Section 6 may be assigned by a Holder to any
transferee or assignee of Registrable Securities upon the transfer or assignment
of all Registrable Securities held by such Holder or a minimum of 20% of shares
of such Registrable Securities; provided that the Company is notified in writing
of such transfer, the proposed transferee or assignee agrees to be bound by the
provisions of this Subscription Agreement.

LENDER:
ADDRESS:


BORROWER:        OMEGA ORTHODONTICS, INC.

DATE:            September   , 1996

PRINCIPAL AMOUNT:$50,000.00

INTEREST RATE:   15% per annum, fixed

PAYMENT TERMS:   Principal - On the Maturity Date, subject to earlier prepayment

MATURITY DATE:   September 30, 1997

COMMON STOCK
 TO BE ISSUED:   10,000 SHARES


This is one of a  series  of  notes  of like  tenor  and  term in the  aggregate
principal  amount of up to FIVE  HUNDRED  THOUSAND  ($500,000.00)  DOLLARS  (the
"Notes")  issued and purchased in  accordance  with or as  contemplated  by that
certain Confidential  Private Placement  Memorandum - OMEGA Orthodontics,  Inc.,
dated as of September 4, 1996, as the same may be amended or  supplemented  from
time to time  (collectively,  the "Placement  Memorandum")  and the Subscription
Agreement for this Note. All capitalized  terms not specifically  defined herein
shall have the same effect as in the Memorandum or the  Subscription  Agreement,
as applicable.

The undersigned Borrower promises to pay to lender whose name and address is set
forth above (hereinafter  "Lender",  which term shall include its successors and
assigns) or order,  in lawful money of the United  States,  at the office of the
Borrower set forth in the  Memorandum  or at such other address the Lender shall
designate in written  notice to the  Borrower,  the  Principal  Amount set forth
above with  interest  thereon or on such part thereof as may have been from time
to time  advanced  and  remain  outstanding  at the  Interest  Rate  hereinabove
specified.  The entire unpaid  Principal  balance with interest then outstanding
shall be due and payable in full on September  30, 1997 (the  "Maturity  Date").
Interest  hereunder  shall  accrue in arrears,  shall be payable  monthly on the
first day of each month commencing  November 1, 1996, and shall be computed on a
360 day 

<PAGE>


basis (i.e.,  interest for each day during which any of the principal balance is
outstanding shall be computed at the Interest Rate hereinabove specified divided
by 360).  Payments  shall be applied,  in order,  to costs of  collection,  late
charges, interest and then Principal.

1. Mandatory Prepayment. The Borrower intends to use the proceeds of the sale of
the Notes to pay for the legal,  accounting  and printing  expenses the Borrower
expects  to incur in  preparing  and  consummating  an initial  public  offering
("IPO") of Common  Stock and  Redeemable  Common  Stock  Purchase  Warrants,  as
reflected in the Memorandum.  Within five days after consummation of the IPO, if
it is consummated, the Borrower shall prepay the entire Principal Amount of this
Note (and the other  Notes),  together  with any  accrued  but  unpaid  interest
thereon.

2.  Acceleration/Events  of Default.  At the option of Lender, the entire unpaid
Principal   balance  hereunder  with  interest  then  outstanding  shall  become
immediately  due and payable upon the occurrence of any of the following  events
of default  (hereinafter  "Events of Default") which are not cured in accordance
with the  provisions of Section 3: (i) failure to pay principal when due on this
Note;  (ii)  failure to pay any  interest on this Note 30 days after  payment is
due;  (iii)  failure to perform any other  covenant of the  Borrower  under this
Note, and such failure continues for 60 days after written notice by the holder;
and (iv) the  making  of an  assignment  for the  benefit  of  creditors,  trust
mortgage or composition  with  creditors or other  arrangement of similar import
by, or the  commencement of any  proceedings  under any bankruptcy or insolvency
Law, now or hereafter enacted by or against Borrower, or any endorser.

      If an Event of Default shall occur and be continuing,  other than an event
of bankruptcy  or insolvency of the Company,  the holders of at least 50% of the
principal amount of the outstanding  Notes may accelerate  maturity of all Notes
upon 10  business  days after  notice of such  acceleration  is  received by the
Company.  If an  Event of  Default  shall  occur  and be  continuing  which is a
bankruptcy  or  insolvency  of the  Company,  the  maturity  of all Notes  shall
immediately  accelerate  without  any  act on the  part  of  any  holder.  After
acceleration upon the Event of Default, but before a judgment or decree based on
acceleration,  the holders of more than 50% in an aggregate  principal amount of
outstanding Notes may rescind and annul such declaration if, among other things,
all Events of Default, other than the non-payment of accelerated principal, have
been cured or waived as provided in the Notes.

      No holder of any Note will have any right to institute any proceeding with
respect to such holder's Note or any remedy thereunder, unless the holders of at
least 50% in an aggregate  principal amount of the outstanding  Notes shall have
made written demand upon the Company for payment for the same continuing  Events
of Default.

3. Borrower's Right to Cure.  Notwithstanding  the foregoing,  Borrower shall at
minimum have the right:  (1) to cure  monetary  defaults  hereunder or under any
instrument, document or undertaking given or entered into in connection herewith
within 15 calendar days after the event of default;  and (2) to cure nonmonetary
defaults hereunder or under any such instrument,  document or undertaking within
30 calendar days after the event of default,  in which event,  this Note and the

<PAGE>



loan evidenced hereby shall be reinstated.  The time periods provided herein for
cure shall be  concurrent  with and not  consecutive  to any other grace periods
which may be provided in or with respect to any obligation having the benefit of
this provision.

4.  Voluntary  Prepayment.  Borrower may prepay this Note in whole or in part at
any time without penalty or premium, upon written notice to Lender.

5. Common Stock Rights.  As and for  additional  consideration  to the Lender in
connection  with the  issuance and  purchase of this Note,  the Borrower  hereby
grants to the Lender the right to receive,  for no  additional  payment,  10,000
shares (the  "Shares")  of the Common  Stock,  par value $.01 per share,  of the
Borrower.  Certificates  for the  Shares  shall  be  issued  in the  name of and
delivered to the Holder upon the execution and delivery of this Note. The Shares
shall be held subject to the  provisions  of, and the Holder of the Shares shall
be entitled to the benefits under, the Subscription Agreement for this Note.

6. Expenses. Borrower agrees to pay all expenses including reasonable attorney's
fees, which Lender may incur in effecting  collection of this Note, upon default
or at maturity.

7. Delays.  Lender shall not, by any act, delay, omission or otherwise be deemed
to have waived any of its rights or remedies  hereunder unless such waiver be in
writing and signed by Lender. A delay,  omission or waiver on one occasion shall
not be deemed a waiver or bar on any  future  occasion  of the same or any other
right.

8. Certain  Waivers.  Borrower hereby (1) waives  presentment,  demand,  notice,
protest  and all other  demands  and notices in  connection  with the  delivery,
acceptance,  performance,  default  or  enforcement  of  this  Note,  except  as
specifically provided herein with respect to notices of nonmonetary default; (2)
waives all suretyship defenses; and (3) assents to any extension or postponement
of the  time of  payment  or any  other  indulgence  or  forbearance  and to the
addition or release of any other party primarily or secondarily liable.

9. Remedies.  Borrower hereby  acknowledges  and agrees that no remedy of Lender
under this Note is intended to be  exclusive of any other  remedy,  and each and
every remedy given  hereunder or now  hereafter  existing at law or in equity by

                  SECTION 3. Form and Execution of Warrant Certificates.

                      (a) The Warrant Certificates shall be substantially in the
form annexed hereto as Exhibit A (the provisions of which are hereby
incorporated herein) and may have such letters, numbers or other marks of
identification or designation and such legends, summaries or endorsements
printed, lithographed or engraved thereon as the Company may deem appropriate
and as are not inconsistent with the provisions of this Agreement, or as may be
required to comply with any law or with any rule or regulation made pursuant
thereto or with any rule or regulation of any stock exchange on which the
Warrants may be listed, or to conform to usage. The Warrant Certificates shall
be dated the date of issuance thereof (whether upon initial issuance, transfer,
exchange or in lieu of mutilated, lost, stolen or destroyed Warrant
Certificates) and issued in registered form. Warrants shall be numbered serially
with the letter W on the Warrants.

                      (b) Warrant Certificates shall be executed on behalf of
the Company by its Chairman of the Board, Chief Executive Officer, President or
any Vice President and by its Treasurer or an Assistant Treasurer or its
Secretary or an Assistant Secretary, by manual signatures or by facsimile
signatures printed thereon, and shall have imprinted thereon a facsimile of the
Company's seal. Warrant Certificates shall be manually countersigned by the
Warrant Agent and shall not be valid for any purpose unless so countersigned. In
case any officer of the Company who shall have signed any of the Warrant
Certificates shall cease to be such officer of the Company before the date of
issuance of the Warrant Certificates or before countersignature by the Warrant
Agent and issue and delivery thereof, such Warrant Certificates, nevertheless,
may be countersigned by the Warrant Agent, issued and delivered with the same
force and effect as though the person who signed such Warrant Certificates had
not ceased to be such officer of the Company. After countersignature by the
Warrant Agent, Warrant Certificates shall be delivered 


                                       6
<PAGE>


by the Warrant Agent to the Registered Holder promptly and without further
action by the Company, except as otherwise provided by Section 4(a) hereof.

                  SECTION 4. Exercise.

                      (a) Warrants in denominations of one or whole number
multiples thereof may be exercised by the Registered Holder thereof commencing
at any time on or after the Initial Warrant Exercise Date, but not after the
Warrant Expiration Date, upon the terms and subject to the conditions set forth
herein and in the applicable Warrant Certificate. A Warrant shall be deemed to
have been exercised immediately prior to the close of business on the Exercise
Date and the person entitled to receive the securities deliverable upon such
exercise shall be treated for all purposes as the holder, upon exercise thereof,
as of the close of business on the Exercise Date. If Warrants in denominations
other than whole number multiples thereof shall be exercised at one time by the
same Registered Holder, the number of full shares of Common Stock which shall be
issuable upon exercise thereof shall be computed on the basis of the aggregate
number of full shares of Common Stock issuable upon such exercise. As soon as
practicable on or after the Exercise Date and in any event within five business
days after such date, if one or more Warrants have been exercised, the Warrant
Agent on behalf of the Company shall cause to be issued to the person or persons
entitled to receive the same a Common Stock certificate or certificates for the
shares of Common Stock deliverable upon such exercise, and the Warrant Agent
shall deliver the same to the person or persons entitled thereto. Upon the
exercise of any one or more Warrants, the Warrant Agent shall promptly notify
the Company in writing of such fact and of the number of securities delivered
upon such exercise and, subject to subsection (b) below, shall cause all
payments of an amount in cash or by check made payable to the order of the
Company, equal to the Purchase Price, to be deposited promptly in the Company's
bank account.

<PAGE>


                      (b) At any time upon the exercise of any Warrants after
one year and one day from the date hereof, the Warrant Agent shall, on a daily
basis, within two business days after such exercise, notify National of the
exercise of any such Warrants and shall, on a weekly basis (subject to
collection of funds constituting the tendered Purchase Price, but in no event
later than five business days after the last day of the calendar week in which
such funds were tendered), remit to National an amount equal to five percent
(5%) of the Purchase Price of such Warrants then being exercised unless National
shall have notified the Warrant Agent that the payment of such amount with
respect to such Warrant is violative of the General Rules and Regulations
promulgated under the Exchange Act, or the rules and regulations of the NASD or
applicable state securities or "blue sky" laws, or the Warrants are those
underlying the Representative's Warrants in which event, the Warrant Agent shall
have to pay such amount to the Company; provided, that the Warrant Agent shall
not be obligated to pay any amounts pursuant to this Section 4(b) during any
week that such amounts payable are less than $1,000 and the Warrant Agent's
obligation to make such payments shall be suspended until the amount payable
aggregates $1,000, and provided further, that, in any event, any such payment
(regardless of amount) shall be made not less frequently than monthly.
Notwithstanding the foregoing, National shall be entitled to receive the
commission contemplated by this Section 4(b) as Warrant solicitation agent only
if: (i) National has provided actual services in connection with the
solicitation of the exercise of a Warrant by a Registered Holder and (ii) the
Registered Holder exercising a Warrant affirmatively designates in writing on
the exercise form on the reverse side of the Warrant Certificate that the
exercise of such Registered Holder's Warrant was solicited by National.

                      (c) The Company shall not be required to issue fractional
shares on the exercise of Warrants. Warrants may only be exercised in such
multiples as are required to permit 


                                       8
<PAGE>


the issuance by the Company of one or more whole shares. If one or more Warrants
shall be presented for exercise in full at the same time by the same Registered
Holder, the number of whole shares which shall be issuable upon such exercise
thereof shall be computed on the basis of the aggregate number of shares
purchasable on exercise of the Warrants so presented. If any fraction of a share
would, except for the provisions provided herein, be issuable on the exercise of
any Warrant (or specified portion thereof), the Company shall pay an amount in
cash equal to such fraction multiplied by the then current market value of a
share of Common Stock, determined as follows:

                   (1) If the Common Stock is listed, or admitted to unlisted
trading privileges on a national securities exchange, or is traded on Nasdaq,
the current market value of a share of Common Stock shall be the closing sale
price of the Common Stock at the end of the regular trading session on the last
business day prior to the date of exercise of the Warrants on whichever of such
exchanges or Nasdaq had the highest average daily trading volume for the Common
Stock on such day; or

                  (2) If the Common Stock is not listed or admitted to unlisted
trading privileges on any national securities exchange, or listed, quoted or
reported for trading on Nasdaq, but is traded in the over-the-counter market,
the current market value of a share of Common Stock shall be the average of the
last reported bid and asked prices of the Common Stock reported by the National
Quotation Bureau, Inc. on the last business day prior to the date of exercise of
the Warrants; or

                  (3) If the Common Stock is not listed, admitted to unlisted
trading privileges on any national securities exchange, or listed, quoted or
reported for trading on Nasdaq, and bid and asked prices of the Common Stock are
not reported by the National Quotation Bureau, Inc., 


                                       9
<PAGE>


the current market value of a share of Common Stock shall be an amount, not less
than the book value thereof as of the end of the most recently completed fiscal
quarter of the Company ending prior to the date of exercise, determined by the
members of the Board of Directors of the Company exercising good faith and using
customary valuation methods.

                  SECTION 5. Reservation of Shares; Listing; Payment of Taxes;
etc.

                      (a) The Company covenants that it will at all times
reserve and keep available out of its authorized Common Stock, solely for the
purpose of issue upon exercise of Warrants, such number of shares of Common
Stock as shall then be issuable upon the exercise of all outstanding Warrants.
The Company covenants that all shares of Common Stock which shall be issuable
upon exercise of the Warrants shall, at the time of delivery thereof, be duly
and validly issued and fully paid and nonassessable and free from all preemptive
or similar rights, taxes, liens and charges with respect to the issue thereof,
and that upon issuance such shares shall be listed on each securities exchange,
if any, on which the other shares of outstanding Common Stock of the Company are
then listed. 

                      (b) The Company covenants that if any securities to be
reserved for the purpose of exercise of Warrants hereunder require registration
with, or approval of, any governmental authority under any federal securities
law before such securities may be validly issued or delivered upon such
exercise, then the Company will file a registration statement under the federal
securities laws or a post-effective amendment, use its best efforts to cause the
same to become effective and to keep such registration statement current while
any of the Warrants are outstanding and deliver a prospectus which complies with
Section 10(a)(3) of the Act, to the Registered Holder exercising the Warrant
(except, if in the opinion of counsel to the Company, such registration is not
required under the federal securities law or if the Company receives a letter


                                       10
<PAGE>


from the staff of the Commission stating that it would not take any enforcement
action if such registration is not effected). The Company will use its best
efforts to obtain appropriate approvals or registrations under state "blue sky"
securities laws with respect to any such securities. However, Warrants may not
be exercised by, or shares of Common Stock issued to, any Registered Holder in
any state in which such exercise would be unlawful.

                      (c) The Company shall pay all documentary, stamp or
similar taxes and other governmental charges that may be imposed with respect to
the issuance of Warrants, or the issuance or delivery of any shares of Common
Stock upon exercise of the Warrants; provided, however, that if shares of Common
Stock are to be delivered in a name other than the name of the Registered Holder
of the Warrant Certificate representing any Warrant being exercised, then no
such delivery shall be made unless the person requesting the same has paid to
the Warrant Agent the amount of transfer taxes or charges incident thereto, if
any.

                      (d) The Warrant Agent is hereby irrevocably authorized as
the Transfer Agent to requisition from time to time certificates representing
shares of Common Stock or other securities required upon exercise of the
Warrants, and the Company will comply with all such requisitions.

                  SECTION 6.  Exchange and Registration of Transfer.

                      (a) Warrant Certificates may be exchanged for other
Warrant Certificates representing an equal aggregate number of Warrants of the
same class or may be transferred in whole or in part. Warrant Certificates to be
exchanged shall be surrendered to the Warrant Agent at its Corporate Office,
and, upon satisfaction of the terms and provisions hereof, the Company shall
execute and the Warrant Agent shall countersign, issue and deliver in exchange
therefor the 


                                       11
<PAGE>


Warrant Certificate or Certificates which the Registered Holder making the
exchange shall be entitled to receive.

                      (b) The Warrant Agent shall keep, at its office, books in
which, subject to such reasonable regulations as it may prescribe, it shall
register Warrant Certificates and the transfer thereof in accordance with
customary practice. Upon due presentment for registration of transfer of any
Warrant Certificate at such office, the Company shall execute and the Warrant
Agent shall issue and deliver to the transferee or transferees a new Warrant
Certificate or Certificates representing an equal aggregate number of Warrants
of the same class.

                      (c) With respect to all Warrant Certificates presented for
registration of transfer, or for exchange or exercise, the subscription or
exercise form, as the case may be, on the reverse thereof shall be duly endorsed
or be accompanied by a written instrument or instruments of transfer and
subscription, in form satisfactory to the Company and the Warrant Agent, duly
executed by the Registered Holder thereof or his attorney-in-fact duly
authorized in writing.

                      (d) A service charge may be imposed by the Warrant Agent
for any exchange or registration of transfer of Warrant Certificates. In
addition, the Company may require payment by such Holder of a sum sufficient to
cover any tax or other governmental charge that may be imposed in connection
therewith.

                      (e) All Warrant Certificates surrendered for exercise or
for exchange in case of mutilated Warrant Certificates shall be promptly
canceled by the Warrant Agent and thereafter retained by the Warrant Agent until
termination of this Agreement.

                      (f) Prior to due presentment for registration of transfer
thereof, the Company and the Warrant Agent may deem and treat the Registered
Holder of any Warrant 


                                       12
<PAGE>


Certificate as the absolute owner thereof and of each Warrant represented
thereby (notwithstanding any notations of ownership or writing thereon made by
anyone other than a duly authorized officer of the Company or the Warrant Agent)
for all purposes and shall not be affected by any notice to the contrary.

                  SECTION 7. Loss or Mutilation. Upon receipt by the Company and
the Warrant Agent of evidence satisfactory to them of the ownership of and the
loss, theft, destruction or mutilation of any Warrant Certificate and (in the
case of loss, theft or destruction) of indemnity satisfactory to them, and (in
case of mutilation) upon surrender and cancellation thereof, the Company shall
execute and the Warrant Agent shall (in the absence of notice to the Company
and/or the Warrant Agent that a new Warrant Certificate has been acquired by a
bona fide purchaser) countersign and deliver to the Registered Holder in lieu
thereof a new Warrant Certificate of like tenor representing an equal aggregate
number of Warrants. Applicants for a substitute Warrant Certificate shall also
comply with such other reasonable regulations and pay such other reasonable
charges as the Warrant Agent may prescribe.

                  SECTION 8. Adjustment of Purchase Price and Number of Shares 
of Common Stock Deliverable.

                      (a) Except as hereinafter provided, in the event the
Company shall, at any time or from time to time after the date hereof and prior
to the Warrant Expiration Date, issue or sell any shares of Common Stock for a
consideration per share less than the Purchase Price or issue any shares of
Common Stock as a stock dividend to the holders of Common Stock, or subdivide or
combine the outstanding shares of Common Stock into a greater or lesser number
of shares (any such issuance, subdivision or combination being herein called a
"Change of Shares"), then, and thereafter upon each further Change of Shares,
the Purchase Price for the Warrants 


                                       13
<PAGE>


(whether or not the same shall be issued and outstanding) in effect immediately
prior to such Change of Shares shall be changed to a price (including any
applicable fraction of a cent to the nearest cent) determined by dividing (i)
the sum of (a) the total number of shares of Common Stock outstanding
immediately prior to such Change of Shares, multiplied by the Purchase Price in
effect immediately prior to such Change of Shares and (b) the consideration, if
any, received by the Company upon such sale, issuance, subdivision or
combination, by (ii) the total number of shares of Common Stock outstanding
immediately after such Change of Shares; provided, however, that in no event
shall the Purchase Price be adjusted pursuant to this computation to an amount
in excess of the Purchase Price in effect immediately prior to such computation,
except in the case of a combination of outstanding shares of Common Stock.

                  For the purposes of any adjustment to be made in accordance
with this Section 8(a), the following provisions shall be applicable:

                           (A) In case of the issuance or sale of shares of
Common Stock (or of other securities deemed hereunder to involve the issuance or
sale of shares of Common Stock) for a consideration part or all of which shall
be cash, the amount of the cash portion of the consideration therefor deemed to
have been received by the Company shall be (i) the subscription price, if shares
of Common Stock are offered by the Company for subscription, or (ii) the public
offering price (before deducting therefrom any compensation paid or discount
allowed in the sale, underwriting or purchase thereof by underwriters or dealers
or others performing similar services, or any expenses incurred in connection
therewith), if such securities are sold to underwriters or dealers for public
offering without a subscription offering, or (iii) the gross amount of cash
actually received by the Company for such securities, in any other case.


                                       14
<PAGE>


                           (B) In case of the issuance or sale (otherwise than
as a dividend or other distribution on any stock of the Company, and otherwise
than on the exercise of options, rights or warrants or the conversion or
exchange of convertible or exchangeable securities) of shares of Common Stock
(or of other securities deemed hereunder to involve the issuance or sale of
shares of Common Stock) for a consideration part or all of which shall be other
than cash, the amount of the consideration therefor other than cash deemed to
have been received by the Company shall be the value of such consideration as
determined in good faith by the Board of Directors of the Company, using
customary valuation methods and on the basis of prevailing market values for
similar property or services.

                           (C) Shares of Common Stock issuable by way of
dividend or other distribution on any stock of the Company shall be deemed to
have been issued immediately after the opening of business on the day following
the record date for the determination of shareholders entitled to receive such
dividend or other distribution and shall be deemed to have been issued without
consideration.

                           (D) The reclassification of securities of the Company
other than shares of Common Stock into securities including shares of Common
Stock shall be deemed to involve the issuance of such shares of Common Stock for
a consideration other than cash immediately prior to the close of business on
the date fixed for the determination of security holders entitled to receive
such shares, and the value of the consideration allocable to such shares of
Common Stock shall be determined as provided in subsection (B) of this Section
8(a).

                           (E) The number of shares of Common Stock at any one
time outstanding shall be deemed to include the aggregate maximum number of
shares issuable (subject to 


                                       15
<PAGE>


readjustment upon the actual issuance thereof) upon the exercise of options,
rights or warrants and upon the conversion or exchange of convertible or
exchangeable securities.

                      (b) Upon each adjustment of the Purchase Price pursuant to
this Section 8, the number of shares of Common Stock purchasable upon the
exercise of each Warrant shall be the number derived by multiplying the number
of shares of Common Stock purchasable immediately prior to such adjustment by
the Purchase Price in effect prior to such adjustment and dividing the product
so obtained by the applicable adjusted Purchase Price.

                      (c) In case the Company shall at any time after the date
hereof issue options, rights or warrants to subscribe for shares of Common
Stock, or issue any securities convertible into or exchangeable for shares of
Common Stock, for a consideration per share (determined as provided in Sections
8(a) and 8(b) and as provided below) less than the Purchase Price in effect
immediately prior to the issuance of such options, rights or warrants, or such
convertible or exchangeable securities, or without consideration (including the
issuance of any such securities by way of dividend or other distribution), the
Purchase Price for the Warrants (whether or not the same shall be issued and
outstanding) in effect immediately prior to the issuance of such options, rights
or warrants, or such convertible or exchangeable securities, as the case may be,
shall be reduced to a price determined by making the computation in accordance
with the provisions of Sections 8(a) and 8(b) hereof, provided that:

                           (A) The aggregate maximum number of shares of Common
Stock, as the case may be, issuable or that may become issuable under such
options, rights or warrants (assuming exercise in full even if not then
currently exercisable or currently exercisable in full) shall be deemed to be
issued and outstanding at the time such options, rights or warrants were issued,
for a consideration equal to the minimum purchase price per share provided for
in such 


                                       16
<PAGE>


options, rights or warrants at the time of issuance, plus the consideration, if
any, received by the Company for such options, rights or warrants; provided,
however, that upon the expiration or other termination of such options, rights
or warrants, if any thereof shall not have been exercised, the number of shares
of Common Stock deemed to be issued and outstanding pursuant to this subsection
(A) (and for the purposes of subsection (E) of Section 8(a) hereof) shall be
reduced by the number of shares as to which options, warrants and/or rights
shall have expired, and such number of shares shall no longer be deemed to be
issued and outstanding, and the Purchase Price then in effect shall forthwith be
readjusted and thereafter be the price that it would have been had adjustment
been made on the basis of the issuance only of the shares actually issued plus
the shares remaining issuable upon the exercise of those options, rights or
warrants as to which the exercise rights shall not have expired or terminated
unexercised.

                           (B) The aggregate maximum number of shares of Common
Stock issuable or that may become issuable upon conversion or exchange of any
convertible or exchangeable securities (assuming conversion or exchange in full
even if not then currently convertible or exchangeable in full) shall be deemed
to be issued and outstanding at the time of issuance of such securities, for a
consideration equal to the consideration received by the Company for such
securities, plus the minimum consideration, if any, receivable by the Company
upon the conversion or exchange thereof; provided, however, that upon the
termination of the right to convert or exchange such convertible or exchangeable
securities (whether by reason of redemption or otherwise), the number of shares
of Common Stock deemed to be issued and outstanding pursuant to this subsection
(B) (and for the purposes of subsection (E) of Section 8(a) hereof) shall be
reduced by the number of shares as to which the conversion or exchange rights
shall have expired or terminated unexercised, and such number of shares shall no
longer be deemed to be


                                       17
<PAGE>


issued and outstanding, and the Purchase Price then in effect shall forthwith be
readjusted and thereafter be the price that it would have been had adjustment
been made on the basis of the issuance only of the shares actually issued plus
the shares remaining issuable upon conversion or exchange of those convertible
or exchangeable securities as to which the conversion or exchange rights shall
not have expired or terminated unexercised.

                           (C) If any change shall occur in the price per share
provided for in any of the options, rights or warrants referred to in subsection
(A) of this Section 8(c), or in the price per share or ratio at which the
securities referred to in subsection (B) of this Section 8(c) are convertible or
exchangeable, such options, rights or warrants or conversion or exchange rights,
as the case may be, to the extent not theretofore exercised, shall be deemed to
have expired or terminated on the date when such price change became effective
in respect of shares not theretofore issued pursuant to the exercise or
conversion or exchange thereof, and the Company shall be deemed to have issued
upon such date new options, rights or warrants or convertible or exchangeable
securities.

                      (d) In case of any reclassification or change of
outstanding shares of Common Stock issuable upon exercise of the Warrants (other
than a change in par value, or from par value to no par value, or from no par
value to par value or as a result of a subdivision or combination), or in case
of any consolidation or merger of the Company with or into another corporation
(other than a merger with a subsidiary of the Company in which merger the
Company is the continuing corporation) and which does not result in any
reclassification or change of the then outstanding shares of Common Stock or
other capital stock issuable upon exercise of the Warrants (other than a change
in par value, or from par value to no par value, or from no par value to par
value or as a result of subdivision or combination) or in case of any sale or


                                       18
<PAGE>


conveyance to another corporation of the property of the Company as an entirety
or substantially as an entirety, then, as a condition of such reclassification,
change, consolidation, merger, sale or conveyance, the Company, or such
successor or purchasing corporation, as the case may be, shall make lawful and
adequate provision whereby the Registered Holder of each Warrant then
outstanding shall have the right thereafter to receive on exercise of such
Warrant the kind and amount of securities and property receivable upon such
reclassification, change, consolidation, merger, sale or conveyance by a holder
of the number of securities issuable upon exercise of such Warrant immediately
prior to such reclassification, change, consolidation, merger, sale or
conveyance and shall forthwith file at the Corporate Office of the Warrant Agent
a statement signed by its Chief Executive Officer, President or a Vice President
and by its Treasurer or an Assistant Treasurer or its Secretary or an Assistant
Secretary evidencing such provision. Such provisions shall include provision for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in Sections 8(a), (b) and (c). The above provisions of
this Section 8(d) shall similarly apply to successive reclassifications and
changes of shares of Common Stock and to successive consolidations, mergers,
sales or conveyances.

                      (e) Irrespective of any adjustments or changes in the
Purchase Price or the number of shares of Common Stock purchasable upon exercise
of the Warrants, the Warrant Certificates theretofore and thereafter issued
shall, unless the Company shall exercise its option to issue new Warrant
Certificates pursuant to Section 2(e) hereof, continue to express the Purchase
Price per share and the number of shares purchasable thereunder as the Purchase
Price per share and the number of shares purchasable thereunder were expressed
in the Warrant Certificates when the same were originally issued.


                                       19
<PAGE>


                      (f) After each adjustment of the Purchase Price pursuant
to this Section 8, the Company will promptly prepare a certificate signed by the
Chairman, Chief Executive Officer or President, and by the Treasurer or an
Assistant Treasurer or the Secretary or an Assistant Secretary, of the Company
setting forth: (i) the Purchase Price as so adjusted, (ii) the number of shares
of Common Stock purchasable upon exercise of each Warrant, after such
adjustment, and (iii) a brief statement of the facts accounting for such
adjustment. The Company will promptly file such certificate with the Warrant
Agent and cause a brief summary thereof to be sent by ordinary first class mail
to each Registered Holder at his last address as it shall appear on the registry
books of the Warrant Agent. No failure to mail such notice nor any defect
therein or in the mailing thereof shall affect the validity thereof except as to
the holder to whom the Company failed to mail such notice, or except as to the
holder whose notice was defective. The affidavit of an officer of the Warrant
Agent or the Secretary or an Assistant Secretary of the Company that such notice
has been mailed shall, in the absence of fraud, be prima facie evidence of the
facts stated therein.

                      (g) No adjustment of the Purchase Price shall be made as a
result of or in connection with (A) the issuance or sale of shares of Common
Stock pursuant to options, warrants, stock purchase agreements and convertible
or exchangeable securities outstanding or in effect on the date hereof and on
the terms described in the final prospectus relating to the public offering
contemplated by the Underwriting Agreement; or (B) the issuance or sale of
shares of Common Stock if the amount of said adjustment shall be less than $.10,
provided, however, that in such case, any adjustment that would otherwise be
required then to be made shall be carried forward and shall be made at the time
of and together with the next subsequent adjustment that shall amount, together
with any adjustment so carried forward, to at least $.10. In addition,
Registered 


                                       20
<PAGE>


Holders shall not be entitled to cash dividends paid by the Company prior to the
exercise of any Warrant or Warrants held by them.

                  SECTION 9. Redemption.

                      (a) Commencing on the Initial Warrant Redemption Date, the
Company may, on 30 days' prior written notice, redeem all the Warrants at ten
cents ($.10) per Warrant, provided, however, that before any such call for
redemption of Warrants can take place, the average closing bid price for the
Common Stock as reported by the Nasdaq SmallCap Market, if the Common Stock is
then traded on Nasdaq SmallCap Market, (or the closing sale price, if the Common
Stock is then traded on a national securities exchange) shall have equalled or
exceeded $______ [200% of the initial public offering price per share of Common
Stock] per share for any twenty (20) trading days within a period of thirty (30)
consecutive trading days ending on the fifth trading day prior to the date on
which the notice contemplated by (b) and (c) below is given (subject to
adjustment in the event of any stock splits or other similar events as provided
in Section 8 hereof).

                      (b) In case the Company shall exercise its right to redeem
all of the Warrants, it shall give or cause to be given notice to the Registered
Holders of the Warrants, by mailing to such Registered Holders a notice of
redemption, first class, postage prepaid, at their last address as shall appear
on the records of the Warrant Agent. Any notice mailed in the manner provided
herein shall be conclusively presumed to have been duly given whether or not the
Registered Holder receives such notice. Not less than five (5) business days
prior to the mailing to the Registered Holders of the Warrants of the notice of
redemption, the Company shall deliver or cause to be delivered to National a
similar notice telephonically and confirmed in writing 


                                       21
<PAGE>


together with a list of the Registered Holders (including their respective
addresses and number of Warrants beneficially owned) to whom such notice of
redemption has been or will be given.

                      (c) The notice of redemption shall specify (i) the
redemption price, (ii) the Redemption Date, which shall in no event be less than
thirty (30) days after the date of mailing of such notice, (iii) the place where
the Warrant Certificate shall be delivered and the redemption price shall be
paid, (iv) if National is engaged as a Warrant solicitation agent, that National
shall receive the commission contemplated by Section 4(b) hereof, and (v) that
the right to exercise the Warrant shall terminate at 5:30 p.m. (New York time)
on the business day immediately preceding the date fixed for redemption. No
failure to mail such notice nor any defect therein or in the mailing thereof
shall affect the validity of the proceedings for such redemption except as to a
holder (a) to whom notice was not mailed or (b) whose notice was defective. An
affidavit of the Warrant Agent or the Secretary or Assistant Secretary of the
Company that notice of redemption has been mailed shall, in the absence of
fraud, be prima facie evidence of the facts stated therein.

                      (d) Any right to exercise a Warrant shall terminate at
5:30 p.m. (New York time) on the business day immediately preceding the
Redemption Date. The redemption price payable to the Registered Holders shall be
mailed to such persons at their addresses of record.

                      (e) The Company shall indemnify National and each person,
if any, who controls National within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act against all loss, claim, damage, expense or
liability (including all expenses reasonably incurred in investigating,
preparing or defending against any claim whatsoever) to which any of them may
become subject under the Act, the Exchange Act or otherwise, arising from the
registration statement or prospectus referred to in Section 5(b) hereof to the
same extent and with 


                                       22
<PAGE>


the same effect (including the provisions regarding contribution) as the
provisions pursuant to which the Company has agreed to indemnify National
contained in Section 7 of the Underwriting Agreement.

                      (f) Five business days prior to the Redemption Date, the
Company shall furnish to National (i) an opinion of counsel to the Company,
dated such date and addressed to National, and (ii) a "cold comfort" letter
dated such date addressed to National, signed by the independent public
accountants who have issued a report on the Company's financial statements
included in such registration statement, in each case covering substantially the
same matters with respect to such registration statement (and the prospectus
included therein) and, in the case of such accountants' letter, with respect to
events subsequent to the date of such financial statements, as are customarily
covered in opinions of issuer's counsel and in accountants' letters delivered to
underwriters in underwritten public offerings of securities.

                  SECTION 10.  Concerning the Warrant Agent.

                      (a) The Warrant Agent acts hereunder as agent and in a
ministerial capacity for the Company and National, and its duties shall be
determined solely by the provisions hereof. The Warrant Agent shall not, by
issuing and delivering Warrant Certificates or by any other act hereunder, be
deemed to make any representations as to the validity or value or authorization
of the Warrant Certificates or the Warrants represented thereby or of any
securities or other property delivered upon exercise of any Warrant or whether
any stock issued upon exercise of any Warrant is fully paid and nonassessable.

                      (b) The Warrant Agent shall not at any time be under any
duty or responsibility to any holder of Warrant Certificates to make or cause to
be made any adjustment of the Purchase Price or the Redemption Price provided in
this Agreement, or to determine 


                                       23
<PAGE>


whether any fact exists which may require any such adjustments, or with respect
to the nature or extent of any such adjustments, when made, or with respect to
the method employed in making the same. It shall not (i) be liable for any
recital or statement of fact contained herein or for any action taken, suffered
or omitted by it in reliance on any Warrant Certificate or other document or
instrument believed by it in good faith to be genuine and to have been signed or
presented by the proper party or parties, (ii) be responsible for any failure on
the part of the Company to comply with any of its covenants and obligations
contained in this Agreement or in any Warrant Certificate, or (iii) be liable
for any act or omission in connection with this Agreement except for its own
negligence, bad faith or willful misconduct.

                      (c) The Warrant Agent may at any time consult with counsel
satisfactory to it (who may be counsel for the Company or for National) and
shall incur no liability or responsibility for any action taken, suffered or
omitted by it in good faith in accordance with the opinion or advice of such
counsel.

                      (d) Any notice, statement, instruction, request,
direction, order or demand of the Company shall be sufficiently evidenced by an
instrument signed by the Chairman of the Board of Directors, Chief Executive
Officer, President or any Vice President (unless other evidence in respect
thereof is herein specifically prescribed). The Warrant Agent shall not be
liable for any action taken, suffered or omitted by it in accordance with such
notice, statement, instruction, request, direction, order or demand reasonably
believed by it to be genuine.

                      (e) The Company agrees to pay the Warrant Agent reasonable
compensation for its services hereunder and to reimburse it for its reasonable
expenses hereunder; the Company further agrees to indemnify the Warrant Agent
and save it harmless from and against any and all losses, expenses and
liabilities, including judgments, costs and counsel fees, for anything done or


                                       24
<PAGE>


omitted by the Warrant Agent in the execution of its duties and powers hereunder
except losses, expenses and liabilities arising as a result of the Warrant
Agent's negligence, bad faith or willful misconduct.

                      (f) The Warrant Agent may resign its duties and be
discharged from all further duties and liabilities hereunder (except liabilities
arising as a result of the Warrant Agent's own gross negligence or willful
misconduct), after giving 30 days' prior written notice to the Company. At least
15 days prior to the date such resignation is to become effective, the Warrant
Agent shall cause a copy of such notice of resignation to be mailed to the
Registered Holder of each Warrant Certificate at the Company's expense. Upon
such resignation, or any inability of the Warrant Agent to act as such
hereunder, the Company shall appoint in writing a new warrant agent. If the
Company shall fail to make such appointment within a period of 15 days after it
has been notified in writing of such resignation by the resigning Warrant Agent,
then the Registered Holder of any Warrant Certificate may apply to any court of
competent jurisdiction for the appointment of a new warrant agent. Any new
warrant agent, whether appointed by the Company or by such a court, shall be a
bank or trust company having a capital and surplus, as shown by its last
published report to its stockholders, of not less than $10,000,000 or a stock
transfer company. After acceptance in writing of such appointment by the new
warrant agent is received by the Company, such new warrant agent shall be vested
with the same powers, rights, duties and responsibilities as if it had been
originally named herein as the Warrant Agent, without any further assurance,
conveyance, act or deed; but if for any reason it shall be necessary or
expedient to execute and deliver any further assurance, conveyance, act or deed,
the same shall be done at the expense of the Company and shall be legally and
validly executed and delivered by the resigning Warrant Agent. Not later than
the effective date of any such appointment the Company shall file 


                                       25
<PAGE>


notice thereof with the resigning Warrant Agent and shall forthwith cause a copy
of such notice to be mailed to the Registered Holder of each Warrant
Certificate.

                      (g) Any corporation into which the Warrant Agent or any
new warrant agent may be converted or merged, any corporation resulting from any
consolidation to which the Warrant Agent or any new warrant agent shall be a
party, or any corporation succeeding to the corporate trust business of the
Warrant Agent or any new warrant agent shall be a successor warrant agent under
this Agreement without any further act, provided that such corporation is
eligible for appointment as successor to the Warrant Agent under the provisions
of the preceding paragraph. Any such successor warrant agent shall promptly
cause notice of its succession as warrant agent to be mailed to the Company and
to the Registered Holders of each Warrant Certificate.

                      (h) The Warrant Agent, its subsidiaries and affiliates,
and any of its or their officers or directors, may buy and hold or sell Warrants
or other securities of the Company and otherwise deal with the Company in the
same manner and to the same extent and with like effect as though it were not
Warrant Agent. Nothing herein shall preclude the Warrant Agent from acting in
any other capacity for the Company or for any other legal entity.

                      (i) The Warrant Agent shall retain for a period of two
years from the date of exercise any Warrant Certificate received by it upon such
exercise.

                  SECTION 11.  Modification of Agreement.

                  The Warrant Agent and the Company may by supplemental
agreement make any changes or corrections in this Agreement (i) that they shall
deem appropriate to cure any ambiguity or to correct any defective or
inconsistent provision or manifest mistake or error herein contained; or (ii)
that they may deem necessary or desirable and which shall not adversely affect
the interests 


                                       26
<PAGE>


of the holders of Warrant Certificates; provided, however, that this Agreement
shall not otherwise be modified, supplemented or altered in any respect except
with the consent in writing of the Registered Holders representing not less than
66-2/3% of the Warrants then outstanding; provided, further, that no change in
the number or nature of the securities purchasable upon the exercise of any
Warrant, or to increase the Purchase Price therefor or to accelerate the Warrant
Expiration Date, shall be made without the consent in writing of the Registered
Holder of the Warrant Certificate representing such Warrant, other than such
changes as are presently specifically prescribed by this Agreement as originally
executed. In addition, this Agreement may not be modified, amended or
supplemented without the prior written consent of National, other than to cure
any ambiguity or to correct any provision which is inconsistent with any other
provision of this Agreement or to make any such change that is necessary or
desirable and which shall not adversely affect the interests of National and
except as may be required by law.

                  SECTION 12.  Notices.

                  All notices, requests, consents and other communications
hereunder shall be in writing and shall be deemed to have been made when

                  SECTION 13.  Governing Law.

                  This Agreement shall be governed by and construed in
accordance with the laws of the State of New York without giving effect to
conflicts of laws.

                  SECTION 14.  Binding Effect.

                  This Agreement shall be binding upon and inure to the benefit
of the Company, National, the Warrant Agent and their respective successors and
assigns and the holders from time to time of Warrant Certificates or any of
them. Nothing in this Agreement is intended or shall be construed to confer upon
any other person any right, remedy or claim, in equity or at law, or to impose
upon any other person any duty, liability or obligation.

                  SECTION 15.  Termination.

                  This Agreement shall terminate at the close of business on the
Expiration Date of all of the Warrants or such earlier date upon which all
Warrants have been exercised or redeemed, except that the Warrant Agent shall
account to the Company for cash held by it and the provisions of Section 10
hereof shall survive such termination.

                  SECTION 16.  Counterparts.

                  This Agreement may be executed in several counterparts, which
taken together shall constitute a single document.

THIS CERTIFIES THAT, FOR VALUE RECEIVED

or registered assigns (the "Registered Holder") is the owner of the number of
Redeemable Warrants (the "Warrants") specified above. Each Warrant initially
entitles the Registered Holder to purchase, subject to the terms and conditions

defined), one fully paid and nonassessable share of Common Stock, $.01 par
value, of Omega Orthodontics, Inc., a Delaware corporation (the "Company"), at

this Warrant Certificate with the Subscription Form on the reverse hereof duly
executed, at the corporate office of Continental Stock Transfer and Trust

Stock] subject to adjustment (the "Purchase Price"), in lawful money of the
United States of America in cash or by check made payable to the Warrant Agent
for the account of the Company.

                This Warrant Certificate and each Warrant represented hereby are
issued pursuant to and are subject in all respects to the terms and conditions
set forth in the Warrant Agreement (the "Warrant Agreement"), dated , 1997 [date

                The term "Expiration Date" shall mean 5:30 p.m. (New York time)
on the date which is fifty-four (54) months after the Initial Warrant Exercise
Date. If each such date shall in the State of New York be a holiday or a day on

securities is effective or an exemption thereunder is available. The Company has
covenanted and agreed that it will file a registration statement under the
Federal securities laws, use its best efforts to cause the same to become
effective, use its best efforts to keep such registration statement current, if
required under the Act, while any of the Warrants are outstanding, and deliver a
prospectus which complies with Section 10(a)(3) of the Act to the Registered
Holder exercising this Warrant. This Warrant shall not be exercisable by a
Registered Holder in any state where such exercise would be unlawful.

                This Warrant Certificate is exchangeable, upon the surrender
hereof by the Registered Holder at the corporate office of the Warrant Agent,
for a new Warrant Certificate or Warrant Certificates of like tenor representing
an equal aggregate number of Warrants, each of such new Warrant Certificates to
represent such number of Warrants as shall be designated by such Registered
Holder at the time of such surrender. Upon due presentment and payment of any
tax or other charge imposed in connection therewith or incident thereto, for
registration of transfer of this Warrant Certificate at such office, a new
Warrant Certificate or Warrant Certificates representing an equal aggregate
number of Warrants will be issued to the transferee in exchange therefor,
subject to the limitations provided in the Warrant Agreement.

Registered Holder shall not be entitled to any rights of a stockholder of the
Company, including, without limitation, the right to vote or to receive
dividends or other distributions, and shall not be entitled to receive any
notice of any proceedings of the Company, except as provided in the Warrant
Agreement.

                Subject to the provisions of the Warrant Agreement, this Warrant
may be redeemed at the option of the Company, at a redemption price of $0.10 per
Warrant, at any time commencing after ______________, 1998 [18 months after the
effective date of the Registration Statement], provided that the average closing
bid price for the Common Stock as reported by the Nasdaq SmallCap Market (or the
closing sale price, if the Common Stock is then traded on a national securities
exchange), shall have equalled or exceeded $_________ [200% of the initial
public offering price per share of Common Stock] per share for any twenty (20)
trading days within a period of thirty (30) consecutive trading days ending on
the fifth trading day prior to the Notice of Redemption, as defined below
(subject to adjustment in the event of any stock splits or other similar
events). Notice of redemption (the "Notice of Redemption") shall be given not
later than the thirtieth day before the date fixed for redemption, all as
provided in the Warrant Agreement. On and after the date fixed for redemption,
the Registered Holder shall have no rights with respect to the Warrants except
to receive the $.01 per Warrant upon surrender of this Warrant Certificate.

                  WHEREAS, the Representative has agreed pursuant to the
underwriting agreement (the "Underwriting Agreement") dated as of the date
hereof between the Company and the several Underwriters listed therein to act as

<PAGE>


                  NOW, THEREFORE, in consideration of the premises, the payment
by the Representative to the Company of an aggregate eighteen dollars ($18.00),
the agreements herein set forth and other good and valuable consideration,
hereby acknowledged, the parties hereto agree as follows:

                  1. Grant. The Representative (or its designees) is hereby
granted the right to purchase, at any time from _______, 1998 [one year from the
effective date of the Registration Statement], until 5:30 P.M., New York time,
on _______, 2002 [five years from the effective date of the Registration
Statement], up to an aggregate of 180,000 shares of Common Stock and/or 180,000
Redeemable Warrants at an initial exercise price (subject to adjustment as

                                      - 2 -

<PAGE>


                  2. Warrant Certificates. The warrant certificates (the
"Warrant Certificates") delivered and to be delivered pursuant to this Agreement
shall be in the form set forth in Exhibit A, attached hereto and made a part
hereof, with such appropriate insertions, omissions, substitutions, and other
variations as required or permitted by this Agreement.

                  3.  Exercise of Warrant.

                  3.1 Method of Exercise. The Warrants initially are exercisable
at an aggregate initial exercise price (subject to adjustment as provided in
Section 8 hereof) per share of Common Stock and Redeemable Warrant set forth in
Section 6 hereof payable by certified or official bank check in New York
Clearing House funds, subject to adjustment as provided in Section 8 hereof.
Upon surrender of a Warrant Certificate with the annexed Form of Election to
Purchase duly executed, together with payment of the Exercise Price (as
hereinafter defined) for the shares of Common Stock and/or Redeemable Warrants
purchased at the Company's principal executive offices in New York (presently
located at 3621 Silver Spur Lane, Acton, California 93510) the registered holder
of a Warrant Certificate ("Holder" or "Holders") shall be entitled to receive a
certificate or certificates for the shares of Common Stock so purchased and a
certificate or certificates for the Redeemable Warrants so purchased. The
purchase rights represented by each Warrant Certificate are exercisable at the
option of the Holder thereof, in whole or in part (but not as to fractional
shares of the Common Stock and Redeemable Warrants underlying the Warrants). In
the event the Company redeems all of the Public Warrants (other than the
Redeemable Warrants underlying the Warrants), then the Warrants may only be
exercised if such exercise is accompanied by the simultaneous exercise of the
Redeemable Warrant(s) underlying the Warrants being so exercised. Warrants may
be exercised to purchase all or part of the shares of Common Stock together with
an equal or unequal number of the Redeemable Warrants represented thereby. 


                                      -3-
<PAGE>


In the case of the purchase of less than all the shares of Common Stock and/or
Redeemable Warrants purchasable under any Warrant Certificate, the Company shall
cancel said Warrant Certificate upon the surrender thereof and shall execute and
deliver a new Warrant Certificate of like tenor for the balance of the shares of
Common Stock and/or Redeemable Warrants purchasable thereunder.

                  3.2 Exercise by Surrender of Warrant. In addition to the
method of payment set forth in Section 3.1 and in lieu of any cash payment
required thereunder, the Holder(s) of the Warrants shall have the right at any
time and from time to time to exercise the Warrants in full or in part by
surrendering the Warrant Certificate in the manner specified in Section 3.1
hereof. The number of shares of Common Stock to be issued pursuant to this
Section 3.2 shall be equal to the difference between (a) the number of shares of
Common Stock in respect of which the Warrants are exercised and (b) a fraction,
the numerator of which shall be number of shares of Common Stock in respect of
which the Warrants are exercised multiplied by the Exercise Price and the
denominator of which shall be the Market Price (as defined in Section 3.3
hereof) of the Common Stock. The number of Redeemable Warrants to be issued
pursuant to this Section 3.2 shall be equal to the difference between (a) the
number of Redeemable Warrants in respect of which the Warrants are exercised and
(b) a fraction, the numerator of which shall be the number of Redeemable
Warrants in respect of which the Warrants are exercised multiplied by the
Exercise Price and the denominator of which shall be the Market Price (as
defined in Section 3.3 hereof) of the Redeemable Warrants. Solely for the
purposes of this paragraph, Market Price shall be calculated either (i) on the
date on which the form of election attached hereto is deemed to have been sent
to the Company pursuant to Section 14 hereof ("Notice Date") or (ii) as the
average of 


                                      -4-
<PAGE>


the Market Prices for each of the five trading days preceding the Notice Date,
whichever of (i) or (ii) is greater.

                  3.3 Definition of Market Price. As used herein, the phrase
"Market Price" at any date shall be deemed to be (i) when referring to the
Common Stock, the last reported sale price, or, in case no such reported sale
takes place on such day, the average of the last reported sale prices for the
last three (3) trading days, in either case as officially reported by the
principal securities exchange on which the Common Stock is listed or admitted to
trading or by the National Association of Securities Dealers Automated Quotation
System ("Nasdaq"), or, if the Common Stock is not listed or admitted to trading
on any national securities exchange or quoted by Nasdaq, the average closing bid
price as furnished by the National Association of Securities Dealers, Inc.
("NASD") through Nasdaq or similar organization if Nasdaq is no longer reporting
such information, or if the Common Stock is not quoted on Nasdaq, as determined
in good faith (using customary valuation methods) by resolution of the members
of the Board of Directors of the Company, based on the best information
available to it or (ii) when referring to a Redeemable Warrant, the last
reported sales price, or, in the case no such reported sale takes place on such
day, the average of the last reported sale prices for the last three (3) trading
days, in either case as officially reported by the principal securities exchange
on which the Redeemable Warrants are listed or admitted to trading or by Nasdaq,
or, if the Redeemable Warrants are not listed or admitted to trading on any
national securities exchange or quoted by Nasdaq, the average closing bid price
as furnished by the NASD through Nasdaq or similar organization if Nasdaq is no
longer reporting such information, or if the Redeemable Warrants are not quoted
on Nasdaq or are no longer outstanding, the Market Price of a Redeemable Warrant
shall equal the difference between the Market Price of the Common Stock and the
Exercise Price of the Redeemable Warrant.

                  4. Issuance of Certificates. Upon the exercise of the
Warrants, the issuance of certificates for shares of Common Stock and/or
Redeemable Warrants and/or other securities, properties or rights underlying
such Warrants and, upon the exercise of the Redeemable Warrants, the issuance of
certificates for shares of Common Stock and/or other securities, properties or
rights underlying such Redeemable Warrants shall be made forthwith (and in any
event within five (5) business days thereafter) without charge to the Holder
thereof including, without limitation, any tax which may be payable in respect
of the issuance thereof, and such certificates shall (subject to the provisions
of Sections 5 and 7 hereof) be issued in the name of, or in such names as may be
directed by, the Holder thereof; provided, however, that the Company shall not
be required to pay any tax which may be payable in respect of any transfer
involved in the issuance and delivery of any such certificates in a name other
than that of the Holder, and the Company shall not be required to issue or
deliver such certificates unless or until the person or persons requesting the
issuance thereof shall have paid to the Company the amount of such tax or shall
have established to the satisfaction of the Company that such tax has been paid.

                  The Warrant Certificates and the certificates representing the
shares of Common Stock and the Redeemable Warrants underlying the Warrants and
the shares of Common Stock underlying the Redeemable Warrants (and/or other
securities, property or rights issuable upon the exercise of the Warrants or the
Redeemable Warrants) shall be executed on behalf of the Company by the manual or
facsimile signature of the then Chairman or Vice Chairman of the Board of
Directors or President or Vice President of the Company. Warrant Certificates
shall be dated the date of execution by the Company upon initial issuance,
division, exchange, substitution or transfer. Certificates representing the
shares of Common Stock and Redeemable Warrants, and the shares of Common Stock
underlying each Redeemable Warrant (and/or other securities, 


                                      -6-
<PAGE>


property or rights issuable upon exercise of the Warrants) shall be dated as of
the Notice Date (regardless of when executed or delivered) and dividend bearing
securities so issued shall accrue dividends from the Notice Date.

                  5. Restriction On Transfer of Warrants. The Holder of a
Warrant Certificate, by its acceptance thereof, covenants and agrees that the
Warrants are being acquired as an investment and not with a view to the
distribution thereof; that the Warrants may not be sold, transferred, assigned,
hypothecated or otherwise disposed of, in whole or in part, for a period of one
(1) year from the date hereof, except to officers of the Representative.

                  6. Exercise Price.

                  6.1 Initial and Adjusted Exercise Price. Except as otherwise
provided in Section 8 hereof, the initial exercise price of each Warrant shall
be $____ [120% of the initial public offering price] per share of Common Stock

and $_____ per Redeemable Warrant [120% of the initial public offering price per
Public Warrant]. The adjusted exercise price shall be the price which shall
result from time to time from any and all adjustments of the initial exercise
price in accordance with the provisions of Section 8 hereof. Any transfer of a
Warrant shall constitute an automatic transfer and assignment of the
registration rights set forth in Section 7 hereof with respect to the Securities
or other securities, properties or rights underlying the Warrants. 

                  6.2 Exercise Price. The term "Exercise Price" herein shall
mean the initial exercise price or the adjusted exercise price, depending upon
the context or unless otherwise specified.

                  7. Registration Rights.

                  7.1 Registration Under the Securities Act of 1933. The
Warrants, the shares of Common Stock and Redeemable Warrants or other securities
issuable upon exercise of the Warrants, and the shares of Common Stock or other
securities issuable upon exercise of the Redeemable Warrants have been
registered under the Securities Act of 1933, as amended (the "Act") pursuant to
the Company's Registration Statement on Form SB-2 (Registration No. 333-
_______) (the "Registration Statement"). All of the representatives and
warranties of the Company contained in the Underwriting Agreement relating to
the Registration Statement, the Preliminary Prospectus and Prospectus (as such
terms are defined in the Underwriting Agreement) and made as of the dates
provided therein, are incorporated by reference herein. The Company agrees and
covenants promptly to file post-effective amendments to such Registration
Statement as may be necessary in order to maintain its effectiveness and
otherwise to take such action as may be necessary to maintain the effectiveness
of the Registration Statement as long as any Warrants are outstanding. In the
event that, for any reason, whatsoever, the Company shall fail to maintain the
effectiveness of the Registration Statement, the certificates representing the
Warrant Securities shall bear the following legend:

                  The securities represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended
                  ("Act"), and may not be offered or sold except pursuant to (i)
                  an effective registration statement under the Act, (ii) to the
                  extent applicable, Rule 144 under the Act (or any similar rule
                  under such Act relating to the disposition of securities), or
                  (iii) an opinion of counsel, if such opinion shall be
                  reasonably satisfactory to counsel to the issuer, that an
                  exemption from registration under such Act is available.

                  7.2 Piggyback Registration. If, at any time commencing after
the date hereof and expiring seven (7) years thereafter, the Company proposes to
register any of its securities


                                      -8-
<PAGE>


under the Act (other than pursuant to Form S-4, Form S-8 or a comparable
registration statement) it will give written notice by registered mail, at least
thirty (30) days prior to the filing of each such registration statement, to the
Representative and to all other Holders of the Warrants and/or the Warrant
Securities of its intention to do so. If the Representative or other Holders of
the Warrants and/or Warrant Securities notify the Company within twenty (20)
business days after receipt of any such notice of its or their desire to include
any such securities in such proposed registration statement, the Company shall
afford the Representative and such Holders of the Warrants and/or Warrant
Securities the opportunity to have any such Warrant Securities registered under
such registration statement.

                  Notwithstanding the provisions of this Section 7.2, the
Company shall have the right at any time after it shall have given written
notice pursuant to this Section 7.2 (irrespective of whether a written request
for inclusion of any such securities shall have been made) to elect not to file
any such proposed registration statement, or to withdraw the same after the
filing but prior to the effective date thereof.

                  7.3 Demand Registration.

                  (a) At any time commencing after the date hereof and expiring
five (5) years thereafter, the Holders of the Warrants and/or Warrant Securities
representing a "Majority" (as hereinafter defined) of such securities (assuming
the exercise of all of the Warrants) shall have the right (which right is in
addition to the registration rights under Section 7.2 hereof), exercisable by
written notice to the Company, to have the Company prepare and file with the
Securities and Exchange Commission (the "Commission"), on one occasion, a
registration statement and such other documents, including a prospectus, as may
be necessary in the opinion of both counsel for the Company and counsel for the
Representative and Holders, in order to


                                      -9-
<PAGE>


comply with the provisions of the Act, so as to permit a public offering and
sale of their respective Warrant Securities for nine (9) consecutive months by
such Holders and any other Holders of the Warrants and/or Warrant Securities who
notify the Company within ten (10) days after receiving notice from the Company
of such request.

                  (b) The Company covenants and agrees to give written notice of
any registration request under this Section 7.3 by any Holder or Holders to all
other registered Holders of the Warrants and the Warrant Securities within ten
(10) days from the date of the receipt of any such registration request.

                  (c) In addition to the registration rights under Section 7.2
and subsection (a) of this Section 7.3, at any time commencing after the date
hereof and expiring five (5) years thereafter, any Holder of Warrants and/or
Warrant Securities shall have the right, exercisable by written request to the
Company, to have the Company prepare and file, on one occasion, with the
Commission a registration statement so as to permit a public offering and sale
for nine (9) consecutive months by any such Holder of its Warrant Securities
provided, however, that the provisions of Section 7.4(b) hereof shall not apply
to any such registration request and registration and all costs incident thereto
shall be at the expense of the Holder or Holders making such request.

                  (d) Notwithstanding anything to the contrary contained herein,
if the Company shall not have filed a registration statement for the Warrant
Securities within the time period specified in Section 7.4(a) hereof pursuant to
the written notice specified in Section 7.3(a) of a Majority of the Holders of
the Warrants and/or Warrant Securities, the Company may, at its option, upon the
written notice of election of a Majority of the Holders of the Warrants and/or
Warrant Securities requesting such registration, repurchase (i) any and all
Warrant Securities of


                                      -10-
<PAGE>


such Holders at the higher of the Market Price per share of Common Stock and per
Redeemable Warrant on (x) the date of the notice sent pursuant to Section 7.3(a)
or (y) the expiration of the period specified in Section 7.4(a) and (ii) any and
all Warrants of such Holders at such Market Price less the Exercise Price of
such Warrant. Such repurchase shall be in immediately available funds and shall
close within two (2) days after the later of (i) the expiration of the period
specified in Section 7.4(a) or (ii) the delivery of the written notice of
election specified in this Section 7.3(d).

                  7.4 Covenants of the Company With Respect to Registration. In
connection with any registration under Section 7.2 or 7.3 hereof, the Company
covenants and agrees as follows:

                  (a) The Company shall use its best efforts to file a
registration statement within thirty (30) days of receipt of any demand
therefor, shall use its best efforts to have any registration statements
declared effective at the earliest possible time, and shall furnish each Holder
desiring to sell Warrant Securities such number of prospectuses as shall
reasonably be requested.

                  (b) The Company shall pay all costs (excluding fees and
expenses of Holder(s)' counsel and any underwriting or selling commissions),
fees and expenses in connection with all registration statements filed pursuant
to Sections 7.2 and 7.3(a) hereof including, without limitation, the Company's
legal and accounting fees, printing expenses, blue sky fees and expenses. The
Holder(s) whose Warrant Securities are the subject of such registration
statement will pay all costs, fees and expenses in connection with any
registration statement filed pursuant to Section 7.3(c).

                  (c) The Company will take all necessary action which may be
required in qualifying or registering the Warrant Securities included in a
registration statement for offering 


                                      -11-
<PAGE>


and sale under the securities or blue sky laws of such states as reasonably are
requested by the Holder(s), provided that the Company shall not be obligated to
execute or file any general consent to service of process or to qualify as a
foreign corporation to do business under the laws of any such jurisdiction.

                  (d) The Company shall indemnify the Holder(s) of the Warrant
Securities to be sold pursuant to any registration statement and each person, if
any, who controls such Holders within the meaning of Section 15 of the Act or
Section 20(a) of the Securities Exchange Act of 1934, as amended ("Exchange
Act"), against all loss, claim, damage, expense or liability (including all
expenses reasonably incurred in investigating, preparing or defending against
any claim whatsoever) to which any of them may become subject under the Act, the
Exchange Act or otherwise, arising from such registration statement but only to
the same extent and with the same effect as the provisions pursuant to which the
Company has agreed to indemnify each of the Underwriters contained in Section 7
of the Underwriting Agreement.

                  (e) The Holder(s) of the Warrant Securities to be sold
pursuant to a registration statement, and their successors and assigns, shall
severally, and not jointly, indemnify the Company, its officers and directors
and each person, if any, who controls the Company within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act, against all loss, claim,
damage, expense or liability (including all expenses reasonably incurred in
investigating, preparing or defending against any claim whatsoever) to which
they may become subject under the Act, the Exchange Act or otherwise, arising
from information furnished by or on behalf of such Holders, or their successors
or assigns, for specific inclusion in such registration statement to the same
extent and with the same effect as the provisions contained in Section 7 of the


                                      -12-
<PAGE>


Underwriting Agreement pursuant to which the Underwriters have agreed to
indemnify the Company.

                  (f) Nothing contained in this Agreement shall be construed as
requiring the Holder(s) to exercise their Warrants prior to the initial filing
of any registration statement or the effectiveness thereof.

                  (g) The Company shall not permit the inclusion of any
securities other than the Warrant Securities to be included in any registration
statement filed pursuant to Section 7.3 hereof, or permit any other registration
statement to be or remain effective during the effectiveness of a registration
statement filed pursuant to Section 7.3 hereof, without the prior written
consent of the Holders of the Warrants and Warrant Securities representing a
Majority of such securities.

                  (h) The Company shall furnish to each Holder participating in
the offering and to each underwriter, if any, a signed counterpart, addressed to
such Holder or underwriter, of (i) an opinion of counsel to the Company, dated
the effective date of such registration statement (and, if such registration
includes an underwritten public offering, an opinion dated the date of the
closing under the underwriting agreement), and (ii) a "cold comfort" letter
dated the effective date of such registration statement (and, if such
registration includes an underwritten public offering, a letter dated the date
of the closing under the underwriting agreement) signed by the independent
public accountants who have issued a report on the Company's financial
statements included in such registration statement, in each case covering
substantially the same matters with respect to such registration statement (and
the prospectus included therein) and, in the case of such accountants' letter,
with respect to events subsequent to the date of such financial


                                      -13-
<PAGE>


statements, as are customarily covered in opinions of issuer's counsel and in
accountants' letters delivered to underwriters in underwritten public offerings
of securities.

                  (i) The Company shall as soon as practicable after the
effective date of the registration statement, and in any event within 15 months
thereafter, make "generally available to its security holders" (within the
meaning of Rule 158 under the Act) an earnings statement (which need not be
audited) complying with Section 11(a) of the Act and covering a period of at
least 12 consecutive months beginning after the effective date of the
registration statement.

                  (j) The Company shall deliver promptly to each Holder
participating in the offering requesting the correspondence and memoranda
described below and to the managing underwriters, copies of all correspondence
between the Commission and the Company, its counsel or auditors and all
memoranda relating to discussions with the Commission or its staff with respect
to the registration statement and permit each Holder and underwriter to do such
investigation, upon reasonable advance notice, with respect to information
contained in or omitted from the registration statement as it deems reasonably
necessary to comply with applicable securities laws or rules of the NASD. Such
investigation shall include access to books, records and properties and
opportunities to discuss the business of the Company with its officers and
independent auditors, all to such reasonable extent and at such reasonable times
and as often as any such Holder or underwriter shall reasonably request.

                  (k) The Company shall enter into an underwriting agreement
with the managing underwriters selected for such underwriting by Holders holding
a Majority of the Warrant Securities requested to be included in such
underwriting, which may be the Representative. Such agreement shall be
satisfactory in form and substance to the Company, each Holder and such managing
underwriter(s), and shall contain such representations, warranties and covenants
by


                                      -14-
<PAGE>


the Company and such other terms as are customarily contained in agreements of
that type used by the managing underwriter(s). The Holders shall be parties to
any underwriting agreement relating to an underwritten sale of their Warrant
Securities and may, at their option, require that any or all of the
representations, warranties and covenants of the Company to or for the benefit
of such underwriter(s) shall also be made to and for the benefit of such
Holders. Such Holders shall not be required to make any representations or
warranties to or agreements with the Company or the underwriter(s) except as
they may relate to such Holders and their intended methods of distribution.

                  (l) In addition to the Warrant Securities, upon the written
request therefor by any Holder(s), the Company shall include in the registration
statement any other securities of the Company held by such Holder(s) as of the
date of filing of such registration statement, including without limitation
restricted shares of Common Stock, options, warrants or any other securities
convertible into shares of Common Stock.

                  (m) For purposes of this Agreement, the term "Majority" in
reference to the Holders of Warrants or Warrant Securities, shall mean in excess
of fifty percent (50%) of the then outstanding Warrants or Warrant Securities
that (i) are not held by the Company, an affiliate, officer, creditor, employee
or agent thereof or any of their respective affiliates, members of their family,
persons acting as nominees or in conjunction therewith and (ii) have not been
resold to the public pursuant to a registration statement filed with the
Commission under the Act.

                  8. Adjustments to Exercise Price and Number of Securities.

                  8.1 Subdivision and Combination. In case the Company shall at
any time subdivide or combine the outstanding shares of Common Stock, the
Exercise Price shall


                                      -15-
<PAGE>


forthwith be proportionately decreased in the case of subdivision or increased
in the case of combination.

                  8.2 Stock Dividends and Distributions. In case the Company
shall pay a dividend in, or make a distribution of, shares of Common Stock or of
the Company's capital stock convertible into Common Stock, the Exercise Price
shall forthwith be proportionately decreased. An adjustment made pursuant to
this Section 8.2 shall be made as of the record date for the subject stock
dividend or distribution.

                  8.3 Adjustment in Number of Securities. Upon each adjustment
of the Exercise Price pursuant to the provisions of this Section 8, the number
of Warrant Securities issuable upon the exercise at the adjusted exercise price
of each Warrant shall be adjusted to the nearest full amount by multiplying a
number equal to the Exercise Price in effect immediately prior to such
adjustment by the number of Warrant Securities issuable upon exercise of the
Warrants immediately prior to such adjustment and dividing the product so
obtained by the adjusted Exercise Price.

                  8.4 Definition of Common Stock. For the purpose of this
Agreement, the term "Common Stock" shall mean (i) the class of stock designated
as Common Stock in the Certificate of Incorporation of the Company as may be
amended as of the date hereof, or (ii) any other class of stock resulting from
successive changes or reclassifications of such Common Stock consisting solely
of changes in par value, or from par value to no par value, or from no par value
to par value. In the event that the Company shall after the date hereof issue
securities with greater or superior voting rights than the shares of Common
Stock outstanding as of the date hereof, the Holder, at its option, may receive
upon exercise of any Warrant either the Warrant Securities or a like number of
such securities with greater or superior voting rights.


                                      -16-
<PAGE>


                  8.5 Merger or Consolidation. In case of any consolidation of
the Company with, or merger of the Company with, or merger of the Company into,
another corporation (other than a consolidation or merger which does not result
in any reclassification or change of the outstanding Common Stock), the
corporation formed by such consolidation or merger shall execute and deliver to
the Holder a supplemental warrant agreement providing that the holder of each
Warrant then outstanding or to be outstanding shall have the right thereafter
(until the expiration of such Warrant) to receive, upon exercise of such
Warrant, the kind and amount of shares of stock and other securities and
property receivable upon such consolidation or merger, by a holder of the number
of securities of the Company for which such Warrant might have been exercised
immediately prior to such consolidation, merger, sale or transfer. Such
supplemental warrant agreement shall provide for adjustments which shall be
identical to the adjustments provided in Section 8. The above provision of this
subsection shall similarly apply to successive consolidations or mergers.

                  8.6 No Adjustment of Exercise Price in Certain Cases. No
adjustment of the Exercise Price shall be made:

                      (a) Upon the issuance or sale of the Warrants or the 
                  Warrant Securities issuable upon the exercise of the Warrants;

                      (b) If the amount of said adjustment shall be less than
                  two cents (2(cent)) per Warrant Security, provided, however,
                  that in such case any adjustment that would otherwise be
                  required then to be made shall be carried forward and shall
                  be made at the time of and together with the next subsequent
                  adjustment which, together with any adjustment so carried
                  forward, shall amount to at least two cents (2(cent)) per
                  Warrant Security.


                                      -17-
<PAGE>


                  9. Exchange and Replacement of Warrant Certificates. Each
Warrant Certificate is exchangeable without expense, upon the surrender thereof
by the registered Holder at the principal executive office of the Company, for a
new Warrant Certificate of like tenor and date representing in the aggregate the
right to purchase the same number of Warrant Securities in such denominations as
shall be designated by the Holder thereof at the time of such surrender.

                  Upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of any Warrant
Certificate, and, in case of loss, theft or destruction, of indemnity or
security reasonably satisfactory to it, and reimbursement to the Company of all
reasonable expenses incidental thereto, and upon surrender and cancellation of
the Warrants, if mutilated, the Company will make and deliver a new Warrant
Certificate of like tenor, in lieu thereof.

                  10. Elimination of Fractional Interests. The Company shall not
be required to issue certificates representing fractions of shares of Common
Stock or Redeemable Warrants upon the exercise of the Warrants, nor shall it be
required to issue scrip or pay cash in lieu of fractional interests, it being
the intent of the parties that all fractional interests shall be eliminated by
rounding any fraction up to the nearest whole number of shares of Common Stock
or Redeemable Warrants or other securities, properties or rights.

                  11. Reservation and Listing of Securities. The Company shall
at all times reserve and keep available out of its authorized shares of Common
Stock, solely for the purpose of issuance upon the exercise of the Warrants and
the Redeemable Warrants, such number of shares of Common Stock or other
securities, properties or rights as shall be issuable upon the exercise thereof.
The Company covenants and agrees that, upon exercise of the Warrants and payment
of the Exercise Price therefor, all shares of Common Stock, Redeemable Warrants
and other


                                      -18-

securities issuable upon such exercise shall be duly and validly issued, fully
paid, non-assessable and not subject to the preemptive rights of any
stockholder. The Company further covenants and agrees that upon exercise of the
Redeemable Warrants underlying the Warrants and payment of the respective
Redeemable Warrant exercise price therefor, all shares of Common Stock and other
securities issuable upon such exercises shall be duly and validly issued, fully
paid, non-assessable and not subject to the preemptive rights of any
stockholder. As long as the Warrants shall be outstanding, the Company shall use
its best efforts to cause all shares of Common Stock issuable upon the exercise
of the Warrants and Redeemable Warrants and all Redeemable Warrants underlying
the Warrants to be listed (subject to official notice of issuance) on all
securities exchanges on which the Common Stock or the Public Warrants issued to
the public in connection herewith may then be listed and/or quoted on the Amex
or Nasdaq.

                  12. Notices to Warrant Holders. Nothing contained in this
Agreement shall be construed as conferring upon the Holders the right to vote or
to consent or to receive notice as a stockholder in respect of any meetings of
stockholders for the election of directors or any other matter, or as having any
rights whatsoever as a stockholder of the Company. If, however, at any time
prior to the expiration of the Warrants and their exercise, any of the following
events shall occur:

                      (a) the Company shall take a record of the holders of its
                  shares of Common Stock for the purpose of entitling them to
                  receive a dividend or distribution payable otherwise than in
                  cash, or a cash dividend or distribution payable otherwise 
                  than out of current or retained earnings or capital surplus 
                  (in accordance with applicable law), as indicated by the 
                  accounting treatment of such dividend or distribution on the

                           (b) the Company shall offer to all the holders of its
                  Common Stock any additional shares of capital stock of the
                  Company or securities convertible into or exchangeable for
                  shares of capital stock of the Company, or any option, right
                  or warrant to subscribe therefor; or

                           (c) a dissolution, liquidation or winding up of the
                  Company (other than in connection with a consolidation or
                  merger) or a sale of all or substantially all of its property,
                  assets and business as an entirety shall be proposed;

then, in any one or more of said events, the Company shall give written notice
of such event at least thirty (30) days prior to the date fixed as a record date
or the date of closing the transfer books for the determination of the
stockholders entitled to such dividend, distribution, convertible or
exchangeable securities or subscription rights, or entitled to vote on such
proposed dissolution, liquidation, winding up or sale. Such notice shall specify
such record date or the date of closing the transfer books, as the case may be.
Failure to give such notice or any defect therein shall not affect the validity
of any action taken in connection with the declaration or payment of any such
dividend, or the issuance of any convertible or exchangeable securities, or
subscription rights, options or warrants, or any proposed dissolution,
liquidation, winding up or sale.

                  13. Redeemable Warrants.

                  The form of the certificate representing Redeemable Warrants
(and the form of election to purchase shares of Common Stock upon the exercise
of Redeemable Warrants and the form of assignment printed on the reverse
thereof) shall be substantially as set forth in Exhibit "A" to the Warrant
Agreement dated as of the date hereof by and between the Company and Continental

<PAGE>


Redeemable Warrant issuable upon exercise of the Warrants shall evidence the
right to initially purchase a fully paid and non-assessable share of Common
Stock at an initial purchase price of $______ [110% of the initial public
offering price per share] from ______ 1997 [six months from the effective date
of the Registration Statement] until 5:30 p.m. New York time on _________ 2002
[5 years from the effective date of the Registration Statement] at which time
the Redeemable Warrants, unless the exercise period has been extended, shall
expire. The exercise price of the Redeemable Warrants and the number of shares
of Common Stock issuable upon the exercise of the Redeemable Warrants are
subject to adjustment, whether or not the Warrants have been exercised and the
Redeemable Warrants have been issued, in the manner and upon the occurrence of
the events set forth in Section 8 of the Redeemable Warrant Agreement, which is
hereby incorporated herein by reference and made a part hereof as if set forth
in its entirety herein. Subject to the provisions of this Agreement and upon
issuance of the Redeemable Warrants underlying the Warrants, each registered
holder of such Redeemable Warrant shall have the right to purchase from the
Company (and the Company shall issue to such registered holders) up to the
number of fully paid and non-assessable shares of Common Stock (subject to
adjustment as provided herein and in the Redeemable Warrant Agreement), free and
clear of all preemptive rights of stockholders, provided that such registered
holder complies with the terms governing exercise of the Redeemable Warrant set
forth in the Redeemable Warrant Agreement, and pays the applicable exercise
price, determined in accordance with the terms of the Redeemable Warrant
Agreement. Upon exercise of the Redeemable Warrants, the Company shall forthwith
issue to the registered holder of any such Redeemable Warrant in his name or in
such name as may be directed by him, certificates for the number of shares of
Common Stock so purchased. Except as otherwise provided in this Agreement, the
Redeemable Warrants 


                                      -21-
<PAGE>


underlying the Warrants shall be governed in all respects by the terms of the
Redeemable Warrant Agreement. The Redeemable Warrants shall be transferable in
the manner provided in the Redeemable Warrant Agreement, and upon any such
transfer, a new Redeemable Warrant Certificate shall be issued promptly to the
transferee. The Company covenants to, and agrees with, the Holder(s) that
without the prior written consent of the Holder(s), which will not be
unreasonably withheld, the Redeemable Warrant Agreement will not be modified,
amended, canceled, altered or superseded, and that the Company will send to each
Holder, irrespective of whether or not the Warrants have been exercised, any and
all notices required by the Redeemable Warrant Agreement to be sent to holders
of Redeemable Warrants.

                  14. Notices.

                  All notices, requests, consents and other communications
hereunder shall be in writing and shall be deemed to have been duly made and
sent when delivered, or mailed by registered or certified mail, return receipt
requested:

                      (a) If to the registered Holder of the Warrants, to the
                  address of such Holder as shown on the books of the Company;
                  or

                      (b) If to the Company, to the address set forth in 
                  Section 3 hereof or to such other address as the Company may
                  designate by notice to the Holders.

                  15. Supplements and Amendments. The Company and the
Representative may from time to time supplement or amend this Agreement without
the approval of any Holders of Warrant Certificates (other than the
Representative) in order to cure any ambiguity, to correct or supplement any
provision contained herein which may be defective or inconsistent with any
provisions herein, or to make any other provisions in regard to matters or
questions arising hereunder which the Company and the Representative may deem
necessary or desirable and 


                                      -22-

which the Company and the Representative deem shall not adversely affect the
interests of the Holders of Warrant Certificates.

                  16. Successors. All the covenants and provisions of this
Agreement shall be binding upon and inure to the benefit of the Company, the
Holders and their respective successors and assigns hereunder.

                  17. Termination. This Agreement shall terminate at the close
of business on _______, 2004. Notwithstanding the foregoing, the indemnification
provisions of Section 7 shall survive such termination until the close of
business on _______, 2010.

                  18. Governing Law; Submission to Jurisdiction. This Agreement
and each Warrant Certificate issued hereunder shall be deemed to be a contract
made under the laws of the State of New York and for all purposes shall be
construed in accordance with the laws of said State without giving effect to the
rules of said State governing the conflicts of laws.

                  The Company, the Representative and the Holders hereby agree
that any action, proceeding or claim against it arising out of, or relating in
any way to, this Agreement shall be brought and enforced in the courts of the
State of New York or of the United States of America for the Southern District
of New York, and irrevocably submits to such jurisdiction, which jurisdiction
shall be exclusive. The Company, the Representative and the Holders hereby
irrevocably waive any objection to such exclusive jurisdiction or inconvenient
forum. Any such process or summons to be served upon any of the Company, the
Representative and the Holders (at the option of the party bringing such action,
proceeding or claim) may be served by transmitting a copy thereof, by registered
or certified mail, return receipt requested, postage prepaid, addressed to it at
the address set forth in Section 14 hereof. Such mailing shall be deemed
personal service and shall be legal and binding upon the party so served in any
action, 


                                      -23-

proceeding or claim. The Company, the Representative and the Holders agree that
the prevailing party(ies) in any such action or proceeding shall be entitled to
recover from the other party(ies) all of its/their reasonable legal costs and
expenses relating to such action or proceeding and/or incurred in connection
with the preparation therefor.

                  19. Entire Agreement; Modification. This Agreement (including
the Underwriting Agreement and the Redeemable Warrant Agreement to the extent
portions thereof are referred to herein) contains the entire understanding
between the parties hereto with respect to the subject matter hereof and may not
be modified or amended except by a writing duly signed by the party against whom
enforcement of the modification or amendment is sought.

                  20. Severability. If any provision of this Agreement shall be
held to be invalid or unenforceable, such invalidity or unenforceability shall
not affect any other provision of this Agreement.

                  21. Captions. The caption headings of the Sections of this
Agreement are for convenience of reference only and are not intended, nor should
they be construed as, a part of this Agreement and shall be given no substantive
effect.

                  22. Benefits of this Agreement. Nothing in this Agreement
shall be construed to give to any person or corporation other than the Company
and the Representative and any other registered Holder(s) of the Warrant
Certificates or Warrant Securities any legal or equitable right, remedy or claim
under this Agreement; and this Agreement shall be for the sole benefit of the
Company and the Representative and any other registered Holders of Warrant
Certificates or Warrant Securities.

                               WARRANT CERTIFICATE

                This Warrant Certificate certifies that , or registered
assigns, is the registered holder of ________ Warrants to purchase initially, at
any time from __________, 1998 [one year from the effective date of the

                                       A-1
<PAGE>


Agreement"). Payment of the Exercise Price shall be made by certified or
official bank check in New York Clearing House funds payable to the order of the
Company or by surrender of this Warrant Certificate.

                No Warrant may be exercised after 5:30 p.m., New York time, on
the Expiration Date, at which time all Warrants evidenced hereby, unless
exercised prior thereto, hereby shall thereafter be void.

                The Warrants evidenced by this Warrant Certificate are part of a
duly authorized issue of Warrants issued pursuant to the Warrant Agreement,
which Warrant Agreement is hereby incorporated by reference in and made a part
of this instrument and is hereby referred to for a description of the rights,
limitation of rights, obligations, duties and immunities thereunder of the
Company and the holders (the words "holders" or "holder" meaning the registered
holders or registered holder) of the Warrants.

                The Warrant Agreement provides that upon the occurrence of
certain events the Exercise Price and the type and/or number of the Company's
securities issuable thereupon may, subject to certain conditions, be adjusted.
In such event, the Company will, at the request of the holder, issue a new
Warrant Certificate evidencing the adjustment in the Exercise Price and the
number and/or type of securities issuable upon the exercise of the Warrants;
provided, however, that the failure of the Company to issue such new Warrant
Certificates shall not in any way change, alter, or otherwise impair, the rights
of the holder as set forth in the Warrant Agreement.

                Upon due presentment for registration of transfer of this
Warrant Certificate at an office or agency of the Company, a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the
aggregate a like number of Warrants shall be issued to the transferee(s) in
exchange for this Warrant Certificate, subject to the limitations provided
herein and in the Warrant Agreement, without any charge except for any tax or
other governmental charge imposed in connection with such transfer.

                Upon the exercise of less than all of the Warrants evidenced by
this Certificate, the Company shall forthwith issue to the holder hereof a new
Warrant Certificate representing such number of unexercised Warrants.

                The Company may deem and treat the registered holder(s) hereof
as the absolute owner(s) of this Warrant Certificate (notwithstanding any
notation of ownership or other writing hereon made by anyone), for the purpose
of any exercise hereof, and of any distribution to the holder(s) hereof, and for
all other purposes, and the Company shall not be affected by any notice to the
contrary.

                All terms used in this Warrant Certificate which are defined in
the Warrant Agreement shall have the meanings assigned to them in the Warrant
Agreement.

"Orthodontists");

      WHEREAS, the MSO was formed and acquired to provide equipment,  facilities
and personnel to, and to manage the non-orthodontic business affairs of, the New

      WHEREAS,  the New PC wishes to retain the MSO to perform the functions and
to provide the  services  described  in this  Agreement  to assist the New PC to

      2.1 General. The MSO shall provide the New PC with comprehensive  practice
management,  financial and marketing services,  and such facilities,  equipment,
and support  personnel as are  reasonably  required by the New PC to operate its
orthodontic  practice at the  Orthodontic  Offices,  as determined by the MSO in
consultation with the New PC. The New PC hereby appoints the MSO as the sole and
exclusive  business manager of the New PC and agrees that the MSO shall have all
power and authority reasonably necessary to manage the non-orthodontic  business
affairs  of the New PC and carry out the MSO's  orthodontic  duties  under  this
Agreement, subject to the requirements of the applicable provisions of State law
relating to the practice of orthodontics. The MSO may perform some or all of its

from time to time. The MSO shall be responsible for all repairs, maintenance and
replacement of the Orthodontic  Offices  including such leasehold  improvements,
fixtures, furniture,  furnishings and equipment, except for repairs, maintenance
and replacement  necessitated by the negligence of the New PC, its employees and
agents (not including the MSO or its employees or agents).  The MSO shall, on an
ongoing  basis,  evaluate and consult with the New PC on the equipment  needs of
and the  efficiency  and  adequacy  of the  Orthodontic  Offices.  The MSO shall
provide   telephone,   facsimile   transmission,   printing,   duplicating   and
transcribing services as needed, as well as all laundry, linen and uniforms.

Practice  Providers  including  orthodontic  assistants and hygienists  shall be
under the direct supervision of the New PC. The New PC shall have sole authority
to employ and terminate the employment of all Practice Providers.  All personnel
placed in the Orthodontic Offices by the MSO shall be subject to the approval of
the New PC, which approval shall not be  unreasonably  withheld,  and the New PC

personnel for any lawful reason.  The MSO shall be responsible for all personnel
wages,

orthodontic,  hygienic or other assistance or services to patients of the New PC
or otherwise  required by applicable "Laws" (as defined in Section 2.6 below) to
be employees of the New PC to provide  services to patients of the  Practice.  A
list of all Practice Providers and their relationship to the New PC is set forth
as Exhibit B attached  hereto and  incorporated  herein by  reference.  Prior to
making any changes in the list of Practice  Providers,  the New PC shall use its
best efforts to consult with the MSO. The New PC also shall use its best efforts
to  consult  with the MSO with  regard to the terms of  contracts  entered  into
between the New PC and the Practice  Providers  and the terms and  conditions of
their employment or engagement as independent contractors.

      2.4 Business  Systems,  Procedures and Forms. In consultation with the New
PC, the MSO shall establish standardized business systems and procedures for the
New PC, including,  but not limited to, patient  scheduling  systems,  treatment
records  system,  financial  reporting and process  control  systems and patient
communication  management systems (the "OMEGA Patient  Scheduling  System") that
are designed to improve the New PC operating  efficiency.  The MSO shall analyze
such  information  on an ongoing  basis in order to advise the New PC on ways of
improving operating efficiencies. The MSO shall provide training to the staff of
the New PC in the  implementation  and operation of such  standardized  business
systems and procedures.  The MSO shall additionally  provide the New PC with and
train the New PC's staff in the use of standardized  clinical forms,  including,
without  limitation,  forms for patient evaluations and treatment plans. The New
PC expressly  acknowledges  and agrees that it shall have no property  rights in
the OMEGA Patient Scheduling System and the other foregoing systems,  procedures

Section 3.8 hereof and be subject to the restrictions on the use, appropriation,
and reproduction of such Confidential Information provided for in Section 3.8.

shall be responsible for and shall establish and maintain systems for the
handling and processing of all purchasing and payment activities and for the
performance of all payroll and payroll accounting functions of the New PC. The

be rendered to the New PC such business, legal and regulatory management
consultation and advice as may be reasonably required or requested by the New PC
and directly related to the operations of the New PC or its compliance with
Federal, state or local laws, rules, regulations or interpretations governing or
applicable to the New PC (collectively, "Laws"); provided, however, that the MSO
shall not be responsible for any services related to malpractice or other
professional service claims or matters not directly related to the operation of
the New PC or its compliance with Laws, or for any legal or tax advice or
services or personal financial services to Dr.

Schmisseur  and the  Orthodontists  (if any) or any employee or agent of the New
PC.

      2.7 Billing, Collection. The MSO shall be responsible for: (i) billing and
collecting payments for all orthodontic and other professional services rendered
by the New PC and the Practice  Providers,  with all such billing and collecting
to be done in the name of the New PC; (ii)  receiving  payments  from  patients,

accounts  receivable  to a  collection  agency or the bringing of a legal action
against a patient  or a payor on the New PC's  behalf.  In seeking  payments  on
behalf  of the New PC  hereunder,  the MSO  shall  act as the New PC's  agent in
billing and collecting professional fees, charges and other accounts owed to the
New PC and shall only bill under the New PC's provider  number.  In this regard,
the New PC appoints the MSO for the Term of this  Agreement in  accordance  with
the provisions of Article 11 hereof as its true and lawful  attorney-in-fact for
the purposes  set forth above in this Section 2.7 and in Section 2.8 below.  The
MSO does not guarantee collection and is not responsible for any loss to the New
PC as a result of any inability to collect fees and charges.

      2.8 Disbursement of Funds.

      (a) All monies collected for the New PC by the MSO pursuant to Section 2.7
above shall be deposited  into an account (the "the New PC Account") with a bank
whose deposits are insured with the Federal  Deposit  Insurance  Corporation and
which  bank is  acceptable  to the MSO and the New PC (the  "Bank").  The New PC
Account  shall  contain  the  name of the New PC,  but the MSO  shall  make  all
disbursements  therefrom. The MSO shall account for all monies so disbursed from
the New PC Account.

      (b)  From  the  funds  collected  and  deposited  by the MSO in the New PC
Account,  the MSO  shall  make  for and on  behalf  of the New PC the  following
disbursements promptly, when payable:

            (1)  Compensation,  including  salaries,  benefits  and other direct

      with the employment of such personnel; and

            (2) All  compensation  payable  to the MSO  pursuant  to  Article  6
      hereof.

      (c) In the  event  the funds in the New PC  Account  will,  at any time be
insufficient  to cover  the  current  portion  of the  foregoing  expenses  when
payable,  the  MSO may  advance  to the New PC the  necessary  funds  to pay the
current  portion of such expenses for the benefit of the New PC, which  advances
will be deemed to be loans to the New PC to be repaid without  interest from the
New PC Account at such times as there are  adequate  funds  therein or upon such
other  terms and at such  times as  agreed  to by the New PC and the MSO,  which
indebtedness shall not be deemed an MSO Expense for purposes of Section 2.9.

complaints,  grievances  and  disputes  involving  the New PC and  the  Practice
Providers  and any  patients or third  parties.  However,  the MSO shall have no
control  over the New  PC's  patients.  All  decisions  concerning  the New PC's
patients shall be made by the New PC and the Practice Providers.

      2.14 Practice Laws.  Notwithstanding any provision in this Agreement,  the
MSO shall not take any action in  connection  with the  services  to be rendered
hereunder that violates any Law, including,  without limitation, the performance
of any  task or the  taking  of any  action  which  violates  the  Business  and
Professions  Code  of  the  State  as it  relates  to  professional  orthodontic
practices.

      2.15 Monthly  Meetings.  The MSO shall  initiate  monthly or more frequent
meetings with the New PC regarding the policies and procedures for the operation
of the New PC.

      2.16  Maintenance  and  Cleaning  Services.  The  MSO  shall  arrange  for
security,  maintenance  and cleaning of the Orthodontic  Offices,  including the
furniture, fixtures and equipment therein.

appropriate  orthodontist  and  other  professionals  (collectively,   "Practice
Associates") for the purposes of accommodating practice growth,  reducing doctor
work schedule,  or planned retirement.  Such search shall include use by the MSO
of a national  journal  advertising  program and networking in the profession to
locate  appropriate  Practice  Associates.  The MSO estimates that it could take
approximately two years for such a search.

The  MSO  will  provide  screening  of all  applicants  and  will  then  present
appropriate  applicants  for final  selection by the New PC. The New PC shall be
responsible for interviewing and selecting each Practice Associate.

After the Practice  Associate(s)  is (are)  selected by the New PC, the MSO will
assist  the New PC with a trial  plan of  approximately  six  months for the new
Practice  Associate(s).  It is understood  that at the end of this period either
the New PC or the new Practice  Associate may terminate  the  relationship.  All
such Practice  Associates  recruited by the MSO as may be accepted by the New PC
shall be employees of the Practice (if so employed)  and not of the MSO. The MSO
will confer with the New PC on an appropriate salary/work-in arrangement for the
new Practice Associate and the final arrangements shall be determined by the New
PC.

                              DUTIES OF THE NEW PC

      3.1 General.  The New PC shall be  responsible  for the  management of its
practice and the Orthodontic  Office, in accordance with the requirements of the
Laws of the State.

      3.2 Employment of the Orthodontists and Rendering of Patient Care. The New
PC shall be responsible for the employment and  professional  supervision of Dr.
Schmisseur  and all  Orthodontists  and the  other  Practice  Providers  and all
orthodontic  care rendered to patients  shall be rendered by Dr.  Schmisseur and
such  Orthodontists.  Additionally,  the New PC  shall  be  responsible  for the
professional  supervision of all other Practice  Providers in their rendering of
patient care.

      3.3 Professional Services. The New PC shall use and occupy the Orthodontic
Offices  designated  on  Schedule  2 hereof  exclusively  for the  practice  and
rendering of orthodontic services, and shall comply with all applicable Laws and
all standards of orthodontic  care. It is expressly  acknowledged by the parties
that the  orthodontic  practice  conducted at the  Orthodontic  Offices shall be
conducted solely by Dr.  Schmisseur and the Orthodontists and the other Practice
Providers  acting under the  supervision  and control of Dr.  Schmisseur and the
Orthodontists (if any), and no other  orthodontist  shall be permitted to use or
occupy the Orthodontic Offices.  The New PC shall provide professional  services
to patients hereunder in compliance at all times with ethical standards and Laws
applying  to the  orthodontic  profession.  The New PC  shall  ensure  that  Dr.
Schmisseur and each Orthodontist who provides  orthodontic  services to patients
is  licensed  by  the  State.  In  the  event  that  any  disciplinary,  medical
malpractice  or other  actions  are  initiated  against  Dr.  Schmisseur  or any
Orthodontist or other Practice Provider, the New PC shall immediately inform the
MSO of such action and the underlying  facts and  circumstances  subject to such
confidentiality  agreement  or  arrangements  as the New PC and  the  MSO  shall
mutually determine at or prior to the time of such disclosure. The New PC agrees
to  cooperate  with and  participate  in  quality  assurance/utilization  review
programs  established  by the MSO or mandated  by  accreditation  and  licensure
standards applicable to the practice of orthodontics. Deficiencies discovered in
the  performance  of any  personnel or in the quality of  professional  services
shall be reported  immediately to the MSO, and appropriate  steps shall be taken
by the New PC at once to remedy such deficiencies.

      3.4 Records.  The New PC will keep or cause to be kept accurate,  complete
and timely  dental and other  records of all  patients.  The  management  of all
dental and patient  files and records  shall  comply  with all  applicable  Laws
regarding their confidentiality and retention and all files and records shall be
located so that they are readily  accessible for patient care,  consistent  with
ordinary records management practices. Such

                                       8
<PAGE>

records  shall be  sufficient  to  enable  the MSO,  on behalf of the New PC, to
obtain  payments for services and related charges and to facilitate the delivery
of quality patient care by the New PC.  Notwithstanding  the foregoing,  patient
dental  records  shall be and remain the property of the New PC and the contents
thereof shall be solely the responsibility of the New PC.

      3.5 Professional  Expenses. The New PC shall be solely responsible for the
cost of professional  licensure fees and board certification fees, membership in
professional associations and continuing professional education incurred by each
Orthodontist  and other  Practice  Provider  employed  by the New PC. The New PC
shall ensure that Dr. Schmisseur and all the  Orthodontists  employed by the New
PC participate in such continuing  education as is necessary for Dr.  Schmisseur
and such the Orthodontists to remain current.

      3.6 Professional Liability Insurance. The New PC shall provide, or arrange
for the  provision  of,  and  maintain  throughout  the Term of this  Agreement,
professional  liability  insurance coverage in accordance with the provisions of
Article 9 hereof. The New PC shall also cooperate in any programs recommended by
the MSO to assure  that each of its  Orthodontists  is  insurable,  and that Dr.
Schmisseur and each  Orthodontist  participates  in an on-going risk  management
program.

      3.7 Employment  Agreement.  The parties  recognize that the services to be
provided  by the  MSO  are  feasible  only  if the  New PC  operates  an  active
orthodontic   practice  to  which  it,  Dr.  Schmisseur  and  each  Orthodontist
associated  with the New PC devote their full time and  attention,  unless other
specific  provisions are made in writing and mutually agreed upon by the MSO and
New PC. The New PC will cause Dr.  Schmisseur and each  individual  Orthodontist
who now is or  hereafter  becomes  affiliated  with the New PC to  enter  into a
written employment agreement (the "Employment  Agreement")  satisfactory in form
and substance to the MSO,  pursuant to which Dr.  Schmisseur or the Orthodontist
shall agree not to establish, operate or provide orthodontic or dental services,
without the prior written  consent of both the New PC and the MSO, at any office
or facility other than the  Orthodontic  Office.  In addition,  such  Employment
Agreement shall provide by its own terms or by a separate  agreement that if Dr.
Schmisseur's or such  Orthodontist's  employment  shall terminate for any reason
during  the  Term of  this  Agreement,  for a  period  of 24  months  after  the
termination of Dr. Schmisseur's or such Orthodontist's Employment Agreement with
the New PC, Dr.  Schmisseur or such  Orthodontist  shall agree not to establish,
operate or provide  orthodontic  or dental  services,  without the prior written
consent  of both the New PC and the MSO,  at any  office  practice  or  facility
whatsoever  providing  services  similar to those  provided by the New PC at any
orthodontic office within a fifteen (15) mile radius. Such Employment  Agreement
(or separate  agreement)  shall also provide,  among other  things,  that in the
event of a breach of Dr.  Schmisseur's  or the  Orthodontist's  agreement not to
compete with the New PC provided for in such  Employment  Agreement (or separate
agreement),  the MSO shall be entitled to receive, in addition to other remedies
and not by way of an election  of  remedies,  liquidated  damages  equaling  the
greater of: (a) Dr. Schmisseur's or such Orthodontist's  income, as shown on the
W-2 form  prepared  by the New PC, for the most  recent  calendar  year;  or (b)
$300,000.  Such  payment  shall  be made  to the  MSO by the New PC  immediately
following   receipt  of  the  payment  from  Dr.  Schmisseur  or  the  breaching
Orthodontist  by the New PC. Each of the MSO and OMEGA shall be expressly  named
as a  third-party  beneficiary  to such  agreements  between  the New PC and Dr.
Schmisseur  and each  Orthodontist  and the rights and  remedies  of the MSO and
OMEGA thereunder or otherwise in respect of the restrictive  covenants set forth
in such agreements shall survive termination of this Agreement.

                                       9

      3.8 Confidentiality. The New PC agrees and acknowledges that all materials
provided by the MSO to the New PC constitute "Confidential  Information" and are
disclosed in confidence and with the understanding that it constitutes  valuable
business information  developed by the MSO with the assistance of OMEGA at great
expenditures of time,  effort and money. The New PC further agrees that it shall
not,  directly or indirectly,  without the express prior written  consent of the
MSO, use or disclose such Confidential Information for any purpose other than in
connection  with the  services  to be  rendered  hereunder.  The New PC  further
agrees:  (i) to keep strictly  confidential  and hold in trust all  Confidential
Information and not disclose such  Confidential  Information to any third party,
including its shareholders, directors, officers, affiliates, partners, employees
and  independent  contractors  without the express prior written  consent of the
MSO; and (ii) to impose this obligation of  confidentiality on its shareholders,
directors,   officers,   affiliates,   partners,   employees   and   independent
contractors.  The  New PC  acknowledges  that  the  disclosure  of  Confidential
Information  to it by the MSO is done in reliance upon its  representations  and
covenants in this Agreement. Upon expiration or termination of this Agreement by
either party for any reason whatsoever,  the New PC shall immediately return and
shall  cause  its  shareholders,   directors,  officers,  affiliates,  partners,
shareholders  and independent  contractors to immediately  return to the MSO all
Confidential  Information,  and  the  New  PC  will  not,  and  will  cause  its
affiliates,  partners,  employees and independent contractors not to, thereafter
use, appropriate, or reproduce such Confidential Information. The New PC further
expressly   acknowledges  and  agrees  that  any  such  use,   appropriation  or
reproduction of any such Confidential  Information by any of the foregoing after
the  expiration or  termination  of this  Agreement  will result in  irreparable
injury to the MSO and OMEGA,  that the remedy at law for the foregoing  would be
inadequate,  and  that  in  the  event  of  any  such  use,  appropriation,   or
reproduction  of any such  Confidential  Information  after the  termination  or
expiration  of this  Agreement,  the MSO and  OMEGA,  in  addition  to any other
remedies or damages  available  to either or both of them,  shall be entitled to
injunctive or other  equitable  relief  without the necessity of proving  actual
damages  but such  rights to relief  shall not  preclude  the MSO and OMEGA from
other remedies which may be available to either or both of them hereunder.

                                    ARTICLE 4
                 PROFESSIONAL SERVICES, CONTROL OF SOLICITATION,
              APPROVAL OF ADVERTISING MATERIAL AND NO RECIPROCATION

      4.1 A  fundamental  understanding  between the parties  hereto is that the
rendering of  orthodontic  services shall be separate and  independent  from the
provision of  administrative,  management and support services by the MSO. Thus,
the  New PC  shall  have  sole  and  absolute  control  of the  delivery  of all
professional  services  and  treatment  rendered to patients at the  Orthodontic
Offices.

      4.2 No employee or other representative of the MSO shall be engaged in, or
allowed to solicit patients on behalf of, the New PC, nor shall the MSO have any
control over the New PC's patients.

      4.3 No  advertising or promotional  materials,  or other  materials of any
nature,   including   billing  and  collection   forms,   reports,   agreements,
correspondence,  or similar materials,  used in connection with the New PC shall
be used or distributed without having first been approved by the New PC.

      4.4 The parties hereby  acknowledge and agree that the benefits  conferred
upon each of them hereunder  neither  require nor are in any way contingent upon
the  admission,  recommendation,  referral,  or any  other  arrangement  for the
provision  of any item or service  offered by the MSO to any patients of the New
PC or its shareholders,  officers, directors, employees,  contractors or agents,
nor are such benefits in any way contingent upon the recommendation, referral or
any other  arrangement  for the provision of any item or service  offered by the
New PC or any of its Practice Providers, employees, contractors or agents.

improvements and fixtures, furniture and equipment at the Orthodontic Offices as
listed from time to time on Schedule 2 attached hereto and  incorporated  herein
by this reference, under the following terms and conditions:

      (a) The MSO is the  lessee by  assignment  under  lease  for the  premises
occupied by the New PC  (collectively,  the  "Master  Lease") a copy of which is
attached hereto as Exhibit A and incorporated herein by this reference.  The New
PC hereby  acknowledges  that the premises  described under the Master Lease are
suitable for the New PC's  orthodontic  practice.  Based and contingent upon the
New PC's  promise to timely pay all  amounts due under this  Agreement,  the MSO
hereby  agrees to sublease the leased  premises to the New PC upon the following
terms and conditions:

            (i) This  sublease  between  the MSO and the New PC of the  premises
      shall be subject to all of the terms and  conditions  of the Master Lease.
      In the event of the  termination of the MSO's interest as lessee under the
      Master  Lease for any  reason,  then the  sublease  created  hereby  shall
      simultaneously terminate,  unless the New PC assumes the obligations under
      the Master Lease in question and the Lessor consents thereto.

            (ii) All of the terms and  conditions  contained in the Master Lease
      are incorporated herein as terms and conditions of the sublease (with each
      reference  therein to "Lessor" and  "Lessee," to be deemed to refer to the
      MSO and the New PC,  respectively)  and, along with the provisions of this
      Section 5.1(b) and Exhibit "A," shall be the complete terms and conditions
      of the sublease created hereby.

            (iii) Notwithstanding the foregoing,  as between the MSO and the New
      PC, the MSO shall  remain  responsible  for  meeting  the  obligations  of
      "Lessee" under the sections  entitled Rent,  Additional  Rent  Adjustment,
      Insurance  on Fixtures,  Liability  Insurance,  Repairs,  and Taxes of the
      Master Lease,  all of which  obligations  shall be considered MSO Expenses
      hereunder and the New PC shall have no monetary obligation in that regard.
      In  addition,  as between the MSO and the New PC, the MSO shall retain the
      right to exercise any options to purchase the  premises,  or other similar
      rights of ownership or  possession,  which may be granted under the Master
      Lease, and the New PC shall have no rights in that regard.

            (iv) In the event this  Agreement  is  terminated  according  to its
      terms, this sublease shall also terminate automatically.

            (v) If the  Master  Lease  contains  an  option  to renew  the terms
      thereof,  the MSO shall  notify  the New PC, at least 30 days prior to the
      expiration of the time for exercising such option, of

                                       12
<PAGE>

      the  MSO's  intention  to  renew  or not to renew  such  term.  If the MSO
      determines  not to renew such term,  the MSO shall  provide or arrange for
      the  provision of  comparable  office space (the  "Substitute  Orthodontic
      Office")  within a radius  of 15 miles of the  Orthodontic  Office,  which
      Substitute  Orthodontic Office shall be subject to the approval of the New
      PC (which  approval shall not be  unreasonably  withheld or delayed).  The
      lease or sublease for such Substitute  Orthodontic  Office, as applicable,
      shall be substituted  for the lease  described on Exhibit A hereto and all
      references  to the "Master  Lease" shall  thereafter  be applicable to the
      lease or sublease for the  Substitute  Orthodontic  Office for purposes of
      this Agreement, ab initio.

            (vi) The  Alternative  Dispute  Resolution  provisions  set forth in
      Article 14 of this Agreement shall not apply to any issues  concerning the
      Sub-Lease,  the New PC's  tenancy  or the MSO's  rights  and  remedies  as
      Sub-Lessor.

      5.2 The MSO  shall  provide  the New PC at the  Orthodontic  Offices  such
additional  leasehold  improvements,   fixtures,   furniture,   furnishings  and
equipment as may be mutually  agreed to with the New PC and reflected  from time
to time on a  supplement  to  Schedule  2  hereto.  The use by the New PC of all
leasehold improvements,  fixtures, furniture, furnishings and equipment provided
hereunder shall be subject to the following conditions:

      (a)  Title  to all such  leasehold  improvements,  fixtures,  furnishings,
furniture and  equipment  shall remain in the MSO and upon  termination  of this
Agreement,  the New PC shall immediately return and surrender all such leasehold
improvements,  fixtures,  furniture,  furnishings and equipment to the MSO in as
good condition as when received, normal wear and tear excepted.

      (b) The MSO shall be fully and  entirely  responsible  for all repairs and
maintenance of all such leasehold improvements, fixtures, furniture, furnishings
and equipment;  provided,  however,  that the New PC agrees that it will use its
best  efforts to prevent  damage,  excessive  wear,  and  breakdown  of all such
leasehold  improvements,  fixtures,  furniture,  furnishings and equipment,  and
shall advise the MSO of any and all needed repairs and equipment failures.

      (c) The  obligation  of the MSO to  provide  the  leasehold  improvements,
fixtures, furniture, furnishings and equipment stated herein shall be concurrent
and co-extensive with the Term of this Agreement.

      5.3. No Warranty.

      (a)  THE  NEW  PC  ACKNOWLEDGES  THAT  THE  MSO  MAKES  NO  WARRANTIES  OR
REPRESENTATIONS,  EXPRESS OR IMPLIED,  AS TO THE  SUITABILITY OR ADEQUACY OF ANY
LEASEHOLD IMPROVEMENTS,  FIXTURES, FURNITURE, FURNISHINGS,  EQUIPMENT, INVENTORY
OR SUPPLIES  PROVIDED OR LEASED OR SUBLEASED  PURSUANT TO THIS AGREEMENT FOR THE
CONDUCT OF AN ORTHODONTICS PRACTICE OR FOR ANY OTHER PARTICULAR PURPOSE.

                                       13
<PAGE>

      (b) Nothing in this Agreement shall be construed to affect or limit in any
way the  professional  discretion  of the  Practice  Providers to select and use
fixtures, furniture, furnishings and equipment, inventory and supplies purchased
or provided  by the MSO in  accordance  with the  provisions  of this  Agreement
insofar as such selection or use constitutes or might constitute the practice of
dentistry or orthodontistry.

                                  COMPENSATION

      As consideration  for the performance of all of its duties and obligations
as  provided  in this  Agreement,  including  but not  limited to, the costs and
expenses  associated  with  furnishing  the  services,  personnel,   facilities,
leasehold improvements, fixtures, furniture, furnishings, equipment, inventories
and supplies provided for herein, the MSO shall receive compensation in the form
of monthly  management fees (the  "Management  Fees") based upon a predetermined
percentage of the "Practice  Revenues",  as defined and determined in accordance
with the  provisions  set forth in Schedule 3 attached  hereto and  incorporated
herein by this reference,  as such Schedule may be amended by the New PC and the
MSO from time to time. It is acknowledged by and between the parties hereto that
the MSO and/or its  affiliates  has (have)  incurred  substantial  expenses  and
future  obligations  in  acquiring  the capital  stock of the MSO,  acquiring or
otherwise  establishing  the  Orthodontic  Offices,  establishing  its  systems,
including fees for consultants and other professionals,  interest expense, lease
obligations,  and costs of furnishing or refurbishing  the premises at which the
Orthodontic   Offices  are  located.   The  MSO  has  also  assumed  substantial
obligations associated with the continuing operation of the Orthodontic Offices,
including  those of  lessee,  obligor  and  guarantor  and  obligor  on loans to
establish and operate the Orthodontic  Offices. The parties,  therefore,  having
considered various  compensation  formulae,  acknowledge and agree that in order
for the MSO to  receive  a fair  and  reasonable  return  for its  expenses  and
obligations,  and a fair return for the lease of the premises and  equipment and
for providing the services contemplated hereunder,  that the agreed compensation
is not excessive.  The New PC acknowledges that the compensation  arrangement is
reasonable  under the  circumstances  noted herein and has executed an Affidavit
attesting  to this fact  which is  attached  hereto and  incorporated  herein as
Exhibit C. In consideration of the foregoing, the parties agree that the monthly
Management Fees payable to the MSO by the New PC for services  rendered pursuant
to this  Agreement  shall be reviewed and subject to  adjustment at the close of
each  year of the  Term of this  Agreement  based  upon  industry  standards  of
practice and the MSO's costs in performing the required services. If the parties
cannot agree within  thirty (30) days prior to the close of any such year on the
terms of any adjustment to the Management  Fees for the following year, then the
then existing  Management  Fees shall remain in effect.  The New PC specifically
agrees  that the MSO may defer  actual  receipt of its  Management  Fees  and/or
advance  monies for purposes of managing the New PC's cash flow, and the MSO may
repay itself such  advances or pay said deferred  Management  Fees when it deems
appropriate.

                                SECURITY INTEREST

MSO pursuant to this Agreement and any funds advanced by the MSO to or on behalf
of the New PC  pursuant  to this  Agreement  and for  the  faithful  and  timely
performance  of all the covenants  and  conditions to be performed by the New PC
under this Agreement, the New PC hereby pledges,  grants, bargains,  assigns and
transfers  to the MSO a security  interest,  pursuant to the Uniform  Commercial
Code of the State,  in and to all Practice  Revenue and accounts  receivable  of
patients of the New PC, together with all proceeds  thereof  (collectively,  the
"Collateral"),  and further agrees not to pledge, assign, transfer or convey any
of the Collateral or any proceeds  therefrom,  without the prior written consent
of the MSO,  except to affiliates of the MSO.  Concurrent  with the execution of
this Agreement,  the New PC shall execute a Security Agreement,  similar in form
and content as that attached hereto as Exhibit D and incorporated herein by this
reference in order that the MSO may perfect its interest in the Collateral.  The
New PC expressly agrees to execute any appropriate UCC-1 Financing Statement and
UCC-1 Fixture filings, if so requested in writing by the MSO.

                                    COVENANTS

      8.1 New PC's Covenants. As further consideration for the MSO's performance

quality of orthodontic care provided.

      (c) During the Term of this Agreement,  the New PC shall not,  directly or

by the MSO,  within a radius  of 15 miles of the  Orthodontic  Office or of such
other orthodontic practice, without the MSO's prior written consent.

      (d) The New PC recognizes the proprietary  interest of OMEGA in and to its
OMEGA  Patient  Scheduling  System and the MSO in its systems for  managing  the
delivery of orthodontic care and all policies,  procedures,  operating  manuals,
forms,  contracts and other information  (collectively,  the "MSO  Information")
regarding such system.  The New PC acknowledges  and agrees that all information
relating  to the  OMEGA  Patient  Scheduling  System  and  the  MSO  Information
constitutes  trade secrets of OMEGA and/or the MSO. The New PC hereby waives any
and all right,  title and  interest  in and to such trade  secrets and agrees to
return all copies of such trade secrets and information relating thereto, at its
expense, upon termination of this Agreement.

      (e) The New PC acknowledges and agrees that OMEGA and the MSO are entitled
to prevent their  respective  competitors  from  obtaining  and utilizing  their
respective trade secrets.  The New PC agrees to hold OMEGA'S and the MSO's trade
secrets in  strictest  confidence  and not to disclose  them or allow them to be
disclosed  directly or indirectly to any person or entity other than persons who
are engaged by the New PC to perform  duties in  connection  with the New PC and
who have a need to know such trade  secrets in the  performance  of their duties
for the New PC, without OMEGA's or the MSO's prior written consent,  as the case
may be. The New PC acknowledges  its fiduciary  obligations to OMEGA and the MSO
and the  confidentiality  of its relationships with OMEGA and the MSO and of any
information  relating to the services and business  methods of OMEGA and the MSO
which it may  obtain  during the term of this  Agreement.  The New PC shall not,
either during the term of this  Agreement or at any time after the expiration or
sooner  termination  hereof,   disclose  to  anyone,  other  than  employees  or
independent  contractors  of OMEGA  and the MSO who use  OMEGA's  and the  MSO's
system in the course of the  performance of their duties,  any  confidential  or
proprietary information or trade secrets obtained by the New PC. The New PC also
agrees to place  any  persons  to whom said  information  is  disclosed  for the
purpose of  performance  under legal  obligation  to treat such  information  as
strictly confidential.

      8.2 MSO's Covenants. As further consideration for the New PC's performance
of the terms and conditions of this Agreement, the MSO covenants, represents and
warrants  (which  covenants,  representations  and warranties  shall survive the
execution of this  Agreement)  that during the Term of this  Agreement,  the MSO
agrees not to  establish,  develop or open any  offices in  affiliation  with an
orthodontist  for the provision of orthodontic  services within a 15 mile radius
of the Orthodontic Offices, without the express written consent of the New PC.

                             INSURANCE AND INDEMNITY

      9.1 Insurance to be Maintained by the New PC.  Throughout the Term of this
Agreement,  the New PC shall  maintain  in full force and  effect  comprehensive

occurrence and $1,000,000  annual  aggregate per Dr.  Schmisseur and each of the
Orthodontists providing services for the New PC and a separate limit for the New
PC. The New PC shall be responsible for all liabilities  within  deductibles and
for all liabilities in excess of the limits of such policies.  The MSO agrees to
negotiate for and cause premiums to be paid on behalf of the New PC with respect
to such insurance.  Premiums and deductibles with respect to such policies shall
not be MSO  Expenses.  The  New PC also  agrees  to name  the MSO and  OMEGA  as
co-insureds.  The New PC agrees to deliver to the MSO and OMEGA a certificate of
insurance indicating such coverage.

      9.2  Insurance to be Maintained  by the MSO.  Throughout  the Term of this
Agreement, the MSO will use reasonable efforts to provide and maintain, as a MSO
Expense, (a) comprehensive professional liability insurance for all professional
employees of the MSO with limits as  determined  reasonable  by the MSO; and (b)
comprehensive  general liability and property insurance covering the Orthodontic
Office premises and operations.

      9.3 Tail Insurance Coverage. The New PC will cause Dr. Schmisseur and each

PC that upon termination of Dr.

<PAGE>

Schmisseur's  or such  Orthodontist's  relationship  with  the  New PC,  for any
reason,  tail  insurance  coverage  will be purchased by Dr.  Schmisseur or such
Orthodontist.  Such  provisions  may be  contained in an  employment  agreement,
restrictive covenant agreement or other agreement entered into by the New PC and
Dr. Schmisseur or the Orthodontist, and the New PC hereby covenants with the MSO
to enforce such provisions relating to the tail insurance coverage or to provide
such  coverage  at the  expense  of the New PC or Dr.  Schmisseur  or each  such
Orthodontist.

      9.4  Additional  Insureds.  The  New PC and  the MSO  agree  to use  their
reasonable  efforts to have each  other  named as an  additional  insured on the
other's respective liability insurance policies.

      9.5 Indemnification.  The New PC shall indemnify, hold harmless and defend
the MSO and  OMEGA  and  their  respective  officers,  directors,  shareholders,
employees and representatives,  from and against any and all liability,  losses,
damages, claims, causes of action, expenses judgments, settlements, lawsuits and
obligations  (including  reasonable  attorneys' fees), whether or not covered by
insurance, caused or asserted to have been caused, directly or indirectly, by or
as a result of the performance of orthodontic services or the performance of any
intentional  acts,  negligent  acts  or  omissions  by  the  New PC  and/or  its
affiliates,  its  shareholders,   agents,  the  Practice  Providers,  its  other
employees and/or its subcontractors (other than the MSO) during the Term hereof.

attorneys'  fees),  caused  or  asserted  to  have  been  caused,   directly  or
indirectly,  by or as a  result  of the  performance  of any  intentional  acts,
negligent  acts  or  omissions  by the  MSO  and/or  its  shareholders,  agents,
employees and/or subcontractors (other than the New PC) during the Term hereof.

Agreement  (the "Stock  Put/Call  Option and Successor  Designation  Agreement")
dated as of even date herewith,  by and among the New PC, Dr. Schmisseur and the
Orthodontists (if any), OMEGA and the MSO.

      10.2 Termination by MSO. MSO may terminate this Agreement as follows:

preceding calendar year and such default shall continue for a period of ten (10)
days after written  notice  thereof has been given to the New PC by the MSO, the
MSO may terminate this Agreement.

      (c) In the event the New PC shall materially default in the performance of
any other duty or obligation imposed upon it by this Agreement, and such default
shall  continue for a period of sixty (60) days after written notice thereof has

the  Management  Fees  collected to the effective  date of such  termination  or
expiration,  the  amounts of any loans or  advances  (including  any accrued but
unpaid  interest  thereon) and all other sums accrued or related to  occurrences
arising at or prior to the date of termination.

                                   ARTICLE 11
                     AUTHORIZED AGENT AND POWERS OF ATTORNEY

      The New PC hereby  designates  the MSO (and its  designees) its authorized
agent and lawful  attorney-in-fact for purposes of depositing  payments,  paying
accounts  payables,  signing  checks,  negotiating  and  signing  contracts  for
services or goods,  securing loans or incurring obligations on behalf of the New
PC;

                                       18
<PAGE>

provided,  however, that all contracts or fees set for services on behalf of the
New PC  will  be  subject  to  final  approval  and  acceptance  by the  New PC.
Additionally, the New PC hereby irrevocably appoints the MSO (and its designees)
its  authorized  agent and  lawful  attorney-in-fact  to  collect  all bills and
accounts  receivable  for  professional  fees,  charges  and other  amounts  and
authorizes the MSO through its designees to take possession of all checks, money
orders  and  similar  instruments  received  as  payment  of  receivables  to be
deposited into the New PC Account.  The New PC hereby  irrevocably  appoints the
MSO as the New PC's attorney-in-fact, with full power and authority in the place
and stead of the New PC, in the MSO's discretion,  to endorse in the name of the
New PC any checks,  payments,  notes,  insurance  payments and money orders,  to
withdraw  funds for payments of expenses,  including  Management  Fees and other
sums  payable to the MSO,  to open and close the New PC  Account  and other bank
accounts,  to take any action and to execute any other  instrument which the MSO
may deem necessary or advisable to accomplish the purposes hereof. The powers of
attorney granted herein are coupled with an interest and are irrevocable.  Third
parties and entities and persons not a party to this  Agreement  are entitled to
rely on the  foregoing  attorneys-in-fact  and an affidavit of the MSO attesting
thereto.  The acceptance of this appointment by the MSO shall not obligate it to
perform any duty or covenant  required to be performed by the New PC under or by
virtue of this Agreement.  Notwithstanding the foregoing powers of attorney, the
New PC shall at any time, on the request of the MSO, sign financing  statements,
security agreements or other agreements necessary or advisable to accomplish the
purpose of this  Agreement.  Upon the New PC's  failure  to sign said  financing
statements,  security  agreements or other agreements,  the MSO is authorized as
the agent of the New PC to sign any such instruments.  The New PC may review all
deposits and expenses upon request.

                                   ARTICLE 12
                       INDEPENDENT CONTRACTOR RELATIONSHIP

      Neither  the New PC nor its  employees  shall  have any claim  under  this
Agreement or otherwise against the MSO for worker's  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 the New PC. Since  neither the New PC nor its  employees  are
employees  of the MSO,  the MSO  shall  not  withhold  on  behalf  of the New PC
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 the New PC.

                                   ARTICLE 13
                                  MISCELLANEOUS

      13.1 Access to Records.  From and after any termination,  each party shall
provide the other party with  reasonable  access to books and records then owned
by it to permit  such  requesting  party to satisfy  reporting  and  contractual
obligations which may be required of it.

      13.2 Patient Records. Upon termination of this Agreement, the New PC shall
retain all patient  dental  records  maintained  by the New PC or the MSO in the
name of the New PC. During the term of this Agreement,  and thereafter,  the New
PC or its designee shall have reasonable access during normal business

                                       19
<PAGE>

hours to the New PC's and the MSO's  records,  including,  but not  limited  to,
records  of  collections,  expenses  and  disbursements  as  kept  by the MSO in
performing the MSO's obligations  under this Agreement,  and the New PC may copy
any or all such records.

      13.3 The New PC's Control Over the Orthodontic  Practice.  Notwithstanding
the authority  granted to the MSO herein,  the MSO and the New PC agree that the
New PC,  personally or through Dr.  Schmisseur or any of its  Orthodontists  (if
any) and other Practice  Providers,  shall have complete control and supervision
over the professional aspects of the New PC's practice, as well as the provision
of all professional services,  including, without limitation, the selection of a
course of treatment for a patient,  the  procedures or materials to be used as a
part of such  course  of  treatment,  and the  manner  in which  such  course of
treatment is carried out by the New PC. The New PC shall have sole  authority to
direct the business,  professional,  and ethical  aspects of the New PC. The MSO
shall have no  authority,  directly or  indirectly,  to  perform,  and shall not
perform, any orthodontic  function,  or to influence or otherwise interfere with
the exercise of the New PC's professional judgment. The MSO may, however, advise
the  New  PC as to the  relationship  between  its  performance  of  orthodontic
functions and the overall administrative and business functioning of the New PC.

                         ALTERNATIVE DISPUTE RESOLUTION

      14.1 Alternative Dispute Resolution.

      (a) If a dispute  arises  under this  Agreement  which  cannot be resolved
informally  by the  parties,  any party may invoke the  procedures  set forth in
Exhibit E hereto and the parties agree to use these procedures, except paragraph
(b) of this Section 14.1, prior to any party pursuing other available  remedies.
The parties  will meet and attempt in good faith to resolve any  controversy  or
claim arising out of or relating to this Agreement.

      (b) Notwithstanding anything in this Section 14.1 to the contrary:

            (i)  Nothing  in this  Section  14.1 shall  preclude  any party from
      seeking a preliminary injunction or other provisional relief, either prior
      to or  during  the  proceeding  provided  for in this  section,  if in its
      judgment  such  action  is  necessary  to avoid  irreparable  damage or to
      preserve the status quo.

            (ii) The  parties  shall  accept  as  correct,  final,  binding  and
      conclusive the  determination by the outside  accountants then employed by
      the MSO as to the  calculation of any and all Management  Fees owed by the
      New PC to the MSO hereunder,  and such determination  shall not be subject
      to the  provisions  of  this  Section  14.1.  Disputes  as to  the  proper
      interpretation  of the  provisions of this  Agreement  which  describe how
      those  amounts  are to be  calculated,  however,  shall be  subject to the
      provisions of this Section 14.1.

            (iii) Any  determination by either party not to renew this Agreement
      in accordance with the terms and provisions of this Agreement shall not be
      subject to the provisions for dispute resolution in this Section 14.1.

      14.2  Waiver of Jury.  With  respect to any  dispute  arising  under or in
connection  with this  Agreement  or any  related  agreement,  as to which legal
action  nevertheless  occurs, each party hereby irrevocably waives all rights it
may have to demand a jury trial.  This waiver is  knowingly,  intentionally  and
voluntarily  made by the  parties  and each  party  acknowledges  that no person
acting  on behalf of the  other  party  has made any  representation  of fact to
induce this  waiver of trial by jury or in any way  modified  or  nullified  its
effect.  The parties each further  acknowledge  that it has been represented (or
has had the  opportunity to be represented) in the signing of this Agreement and
in the making of this waiver by independent  legal counsel,  selected of its own
free will,  and that it has had the  opportunity  to discuss  this  waiver  with
counsel.  Each party further  acknowledges  that it has read and understands the
meaning and ramifications of this waiver provision.

                                   ARTICLE 15
                               GENERAL PROVISIONS

      15.1 Notices.  Any notice to be given pursuant to this Agreement  shall be
deemed  effective if given  personally,  or by  telephone,  telegram,  telecopy,
facsimile  or other  electronic  transmission,  or by  letter to an  officer  or
administrator  of OMEGA,  the MSO or the New PC,  as the case may be.  Notice in
person,  or by telephone,  telegram or electronic  transmission  shall be deemed
effective when given. Notice by mail shall be deemed effective  seventy-two (72)
hours after  deposit in the United  States mails,  and properly  addressed  with

      Attn: Robert R. Schmisseur, D.D.S.


or such other  address as may be furnished by the New PC to the MSO from time to
time in writing.

      Attn: Robert Schulhof


or other such  addresses  as may be furnished by the MSO to the New PC from time
to time in writing.

      15.2 Confidentiality.  No party hereto shall disseminate or release to any
third party any information  regarding any provision of this  Agreement,  or any
financial information regarding the other parties (past, present or future) that
was obtained in the course of the negotiation of this Agreement or in the course
of

                                       21
<PAGE>

the performance of this Agreement, without the other party's or parties' (as the
case may be) written approval;  provided, however, the foregoing shall not apply
to information  which is required to be disclosed by Law,  including  federal or
state securities laws, or pursuant to court order.

      15.3 Contract Modifications for Prospective Legal Events. In the event any
state or  federal  Laws,  now  existing  or  enacted  or  promulgated  after the
effective  date of this  Agreement,  are  interpreted  by judicial  decision,  a
regulatory  agency  or legal  counsel  for both  parties  in such a manner as to
indicate that the structure of this  Agreement may be in violation of such Laws,
the New PC and the MSO shall amend this  Agreement as necessary.  To the maximum
extent possible,  any such amendment shall preserve the underlying  economic and
financial arrangements between the New PC and the MSO.

      15.4  Remedies  Cumulative.  No  remedy  set  forth in this  Agreement  or
otherwise conferred upon or reserved to any party shall be considered  exclusive
of any other  remedy  available  to any party,  but the same shall be  distinct,
separate  and  cumulative  and may be  exercised  from  time to time as often as
occasion may arise or as may be deemed expedient.

      15.5 No Obligation to Third Parties. None of the obligations and duties of
the MSO or the New PC under this Agreement  shall in any way or in any manner be
deemed to create  any  obligation  of the MSO or of the New PC to, or any rights
in, any person or entity not a party to this  Agreement  other than OMEGA  which
shall be deemed a party for limited purposes as set forth in this Agreement.

      15.6 Entire Agreement. This Agreement including the Schedules and Exhibits
hereto,  together  with the Stock  Put/Call  Option  and  Successor  Designation
Agreement of even date herewith and the Employment  Agreement(s)  (including the
related  non-competition  agreements  or  covenants),   constitutes  the  entire
agreement between the parties concerning this subject matter, and supersedes all
prior and contemporaneous agreements,  representations and understandings of the
parties  concerning  the  contents  hereof.  No  supplement,   modification,  or
amendment to this Agreement  shall be binding unless  executed in writing by all
of the parties hereto,  except as otherwise provided herein. No waiver of any of
the provisions of this  Agreement  shall be deemed to constitute a waiver of any
other provision, whether similar or not similar, nor shall any waiver constitute
a continuing  waiver.  No waiver shall be binding unless  executed in writing by
the party making the waiver.

      15.7  Assignment.  The  rights and the  duties of the  parties  under this
Agreement may not be assigned or transferred  without the prior written  consent
of the non-assigning  party,  which consent shall not be unreasonably  withheld;
provided,  however,  that the MSO shall be  permitted  to assign  its rights and
obligations  hereunder without the consent of the New PC to any person,  firm or
corporation  controlled by the MSO,  controlling the MSO or under common control
with the MSO.

      15.8  Attorneys'  Fees.  If any  mediation or  arbitration  or other legal
action or  proceeding  is  brought  to enforce  this  Agreement,  because of any
alleged  breach  hereof,  or for a  declaration  of any rights  and  obligations
hereunder,  the  prevailing  party in such mediation or  arbitration,  action or
proceeding  shall be entitled to recover its costs incurred  therein,  including
reasonable  attorneys'  fees, in addition to any other relief to which it may be
entitled,  all as determined  and awarded by the parties in such mediation or by
the arbitrator or court as

                                       22
<PAGE>

part of its judgment or decision therein, as the case may be.

      15.9 Governing  Law. This Agreement  shall be governed by and construed in
accordance with the laws of the State.  The parties  acknowledge that the MSO is
not  authorized or qualified to engage in any activity which may be construed or
deemed to constitute  the practice of dentistry or  orthodontics.  To the extent
any act or service  required of the MSO in this Agreement should be construed or
deemed,  by any  governmental  authority,  agency  or  court to  constitute  the
practice of dentistry or orthodontics, the performance of said act or service by
the MSO shall be deemed waived and forever  unenforceable  and the provisions of
Section 15.14 shall be applicable.

      15.10 Events  Excusing  Performance.  Neither party shall be liable to the
other party for failure to perform any of the  services  required  herein in the
event of strikes, lock-outs, calamities, acts of God, unavailability of supplies
or other  events over which that party has no control for so long as such events
continue, and for a reasonable period of time thereafter.

      15.11  Compliance with Applicable Laws. Both parties shall comply with all
applicable  Laws and  restrictions  imposed  thereunder  in the conduct of their
obligations under this Agreement.

      15.12 Language  Construction.  The parties acknowledge that each party and
its counsel have reviewed and revised this Agreement and that the normal rule of
construction to the effect that any  ambiguities are to be resolved  against the
drafting party shall not be employed in the interpretation of this Agreement.

      15.13  Amendments.  This  Agreement  may be  amended  only by the  written
consent of both parties.

      15.14  Severability.  In the event any provision of this Agreement is held
by a court of competent  jurisdiction  to be illegal or  unenforceable,  (i) the
parties  shall  amend  this  Agreement  in  order to carry  out the  intent  and
essential  business  purposes of this Agreement as closely  possible  within the
requirements of applicable  provisions of Law as determined by such a court, and
(ii) the remaining provisions of this Agreement shall continue in full force and
effect.

      15.15 No Waiver.  The waiver by either party to this  Agreement of any one
or more defaults, if any, on the part of the other party, shall not be construed
to operate as a waiver of the other or future defaults under this Agreement.

      15.16  Captions.  Captions to paragraphs in this Agreement are for ease of
reference, and shall not be considered an interpretation of the paragraph.

      15.17 Counterparts.  This Agreement may be executed  simultaneously in one
or more counterparts, each of which shall be deemed an original.

                                   SCHEDULE 3

                         COMPENSATION - MANAGEMENT FEES


      The MSO shall receive,  as compensation  for the performance of all of its
obligations and duties contained in the Agreement, monthly Management Fees in an
amount equal to Seventy Five Percent (75%) of the Practice Revenues, and the New
PC shall be entitled to Twenty Five  Percent  (25%) of such  Practice  Revenues,
except as the parties may otherwise  agree from time to time in writing.  At the
end of each twelve (12) month period  during the Term the MSO shall  provide the
New PC with an unaudited  internal  accounting of the MSO Expenses,  prepared in
accordance  with the  accrual  method  of  accounting.  If the MSO  Expenses  as
reflected in such  accounting as having been paid by the MSO are less than sixty
(60%) percent of the Practice Revenues for such twelve month period, fifty (50%)
percent  of such  difference  shall  be  returned  by the MSO to the New PC as a
profit incentive rebate (the "Rebate").  If the Agreement to which this Schedule
3 is attached is terminated or expires,  the foregoing  Management Fees shall be
payable to the MSO based on all  Practice  Revenue  collected  as of the date of
termination or expiration.

      Payment  to the MSO  shall be made in  monthly  installments  based on the
Practice Revenues realized by the MSO for services rendered  hereunder.  The MSO
shall  distribute the proceeds from the New PC Account and allocate the proceeds
between the MSO and the New PC as described  above, on or before the 15th day of
the succeeding  month.  In the event the 15th day falls on a weekend or holiday,
then said  distribution  shall be made on the next  business  day.  The  parties
hereto may agree to handle such matters in a different manner.

      For  purposes  of this  Agreement,  "Practice  Revenues"  shall mean gross
collections  of all  revenues  generated  by or on behalf of the New PC (whether
through subsidiaries or affiliates), including, but not limited to, all fees and
charges collected as a result of professional  orthodontic services furnished to
patients by the New PC and for any other  goods or services  sold or provided to
such patients.

AFFIDAVIT


      I, Robert R. Schmisseur, D.D.S., declare:

      I am an  orthodontist,  duly  licensed  in the  State  of  Illinois  and I
practice through a professional  corporation under the name  ______________ (the
"New PC").

      I have had substantial  experience in the practice of the Orthodontics and
in managing and operating an orthodontic office.

      In  the  course  of  operating   orthodontic   offices,  I  have  acquired
significant  knowledge as to the  overhead  costs  incurred  and gross  receipts
generated by similar types of orthodontic offices.  Further, I am fully aware of
the non-orthodontic, operational, accounting, billing, financing, management and
personnel requirements of an orthodontic office and the cost factors involved in
providing  such  management,   personnel,  accounting,  billing,  financing  and
operation.

      I  have  thoroughly   reviewed  the  Management  Services  Agreement  (the
"Agreement"),  which is effective as of ________________,  1997, between the New
PC and Omega Orthodontics of Champaign,  Inc. (the "MSO") concerning the duties,
responsibilities and obligations undertaken by the MSO in managing and operating
all  non-orthodontic  aspects of the  Orthodontic  Office as contemplated by the
Agreement.

      I  have  reviewed  the  prior  operating   financial   statements  of  the
orthodontic office located at 1701 South Prospect, Champaign, Illinois 61820 and
an operating budget and estimated income of the orthodontic office, which, in my
opinion, can reasonably be expected from the operation of said office.

      In my opinion,  based upon my experience,  the Management  Fees of Seventy
Five  Percent  (75%)  of  "Practice  Revenues"  to be  charged  by  the  MSO  as
contemplated  by the  Agreement,  will afford it a reasonable  but not excessive
return for its services rendered and obligations incurred. In addition,  the New
PC Twenty Five Percent (25%) of "Practice Revenues" retained by the New PC, will
provide reasonable earnings for the performance of orthodontic services.

      I declare under  penalty of perjury that the  foregoing  statement is true
and correct to the best of my knowledge and belief.

      Executed at      , ________ this     day of        , 1997.


                                                   ____________________________

                               SECURITY AGREEMENT


      THIS  SECURITY  AGREEMENT  is  effective as of the ______ day of _________
1997, by _____________________,  PC, an Illinois corporation (the "New PC"), and
Robert R. Schmisseur, D.D.S. ("Dr. Schmisseur") who is duly licensed to practice
orthodontics in the State and Omega Orthodontics of Champaign,  Inc., a Delaware
corporation (the "MSO") with reference to the following facts:

      WHEREAS,  pursuant to a Management  Services  Agreement (the "Agreement"),
dated as of the date hereof,  between the New PC and the MSO, as  assurance  and
collateral  security for the payment of the monthly  Management Fees owed to the
MSO pursuant to the Agreement and any funds  advanced by the MSO to or on behalf
of the  New PC  pursuant  to the  Agreement  and  for the  faithful  and  timely
performance  of all the covenants  and  conditions to be performed by the New PC
under  the  Agreement  (collectively,  the  "Obligations")  the New PC agreed to
pledge,  grant,  bargain,  assign and  transfer to the MSO a security  interest,
pursuant to the Uniform  Commercial  Code of the State,  in and to all  Practice
Revenue and the accounts receivable of patients of the New PC, together with all
proceeds thereof (collectively, the "Collateral");

      WHEREAS,  the New PC is obligated as a condition to the MSO's  performance
under the Agreement to execute and deliver this Security Agreement;

      NOW, THEREFORE, in consideration of the foregoing and of the covenants and
agreements hereinafter set forth, the parties hereto agree as follows:

      1. Grant of Security Interest.  As and for collateral security for payment
by the New PC of the  Obligations  and any and all  amounts  payable  under this
Security Agreement (collectively,  the "Secured Obligations"), the New PC hereby
pledges, grants,  bargains,  assigns and transfers to the MSO, and grants to the
MSO a security  interest in, the Collateral.  Dr. Schmisseur shall cause the New
PC to perform fully and on a timely basis all of the New PC's obligations  under
this Security  Agreement.  The MSO may at its option file a financing  statement
(Form UCC-1) in order to perfect its security interest hereunder.

      2. Representations and Warranties.  The New PC represents and warrants all
of the accounts  receivable  constituting a portion of the Collateral of the New
PC pledged to the MSO are and will be validly created obligations of each of the
obligors who incurred same for services actually rendered in the ordinary course
of business of the New PC. Further,  the New PC represents and warrants that the
Collateral is not subject to any lien, pledge,  charge,  encumbrance or security
interest or right or option on the part of any third person.

      3. Release of Security Interest. Upon the termination of the Agreement and
payment in full of the accrued  Management Fees thereunder and any and all other
Secured Obligations,  the MSO shall release its security interest hereunder, and
will deliver to the New PC any property forming part of the Collateral delivered
to the MSO and then held by the MSO hereunder.

      4.  Realization  of  Collateral.  The MSO shall have,  with respect to the
Collateral, the rights and

                                       35
<PAGE>

obligations of a secured party under the Uniform  Commercial  Code as adopted in
the  state of  Illinois  (the  "State").  Such  rights  shall  include,  without
limitation, the following:

            A. The right,  upon  default,  to have the  Collateral,  or any part
      thereof, transferred to its own name or to the name of its nominee;

            B. The right,  upon default,  to sell,  assign or deliver as much of
      the  Collateral  as  is  reasonably   necessary  to  repay  the  defaulted
      indebtedness   (together  with  expenses  attendant  upon  such  sale  and
      repayment),  at public or private sale,  as the MSO may elect,  either for
      cash or on  credit,  without  assumption  of any credit  risk and  without
      demand or advertisement (unless otherwise required by law).

            C. The New PC hereby irrevocably authorizes the MSO to sign and file
      financing  statements  naming  the New PC as the debtor and the MSO as the
      secured  party,  at any time with respect to any  Collateral,  without the
      signature of the New PC. The New PC hereby irrevocably appoints the MSO as
      the New PC's attorney-in-fact,  with full authority in the place and stead
      of the New PC and in the  name of the  New  PC,  from  time to time in the
      MSO's  discretion,  to take any action and to execute any instrument which
      the MSO may deem necessary or advisable to accomplish the purposes hereof.
      The  attorney-in-fact  granted  herein is coupled  with an interest and is
      irrevocable.  Third  parties and  entities and persons not a party to this
      Security  Agreement are entitled to rely on this  attorney-in-fact  and an
      affidavit of the MSO attesting thereto. The acceptance of this appointment
      by the MSO shall not obligate it to perform any duty or covenant  required
      to be  performed  by the New PC  under  or by  virtue  of the  Collateral.
      Notwithstanding  the foregoing power of attorney,  the New PC shall at any
      time on the  request  of the  MSO,  sign  Financing  Statements,  security
      agreements or other  agreements with respect to any  Collateral.  Upon the
      New PC's failure to sign said Financing Statements, security agreements or
      other agreements, the MSO is authorized as the agent of the New PC to sign
      any such  instruments.  Upon the request of the MSO,  the New PC agrees to
      pay all filing fees and to  reimburse  the MSO on demand for all costs and
      expenses of any kind (including,  without limitation, legal fees) incurred
      in any way in connection with the Collateral.

      5.  Purchase  of  Collateral.  At any such  private or public  sale of the
Collateral  or  part  thereof,  the  MSO may  purchase  and pay for the  same by
cancellation of such portion of the Obligations, equal to the purchase price and
free of any  right  of  redemption  on the part of the New PC.  the MSO  agrees,
however,  that the New PC shall  have all  rights,  including  rights of notice,
provided by the  Uniform  Commercial  Code as adopted in the State.  In any case
where notice is required,  five days' notice shall be deemed reasonable  notice.
In the event of any sale  hereunder,  the MSO shall  apply the  proceeds  in the
order set forth  below in  Paragraph  6 hereof.  the MSO may have  resort to the
Collateral or any portion thereof with no requirements on the part of the MSO to
proceed first against any other person or property.

      6. Application of Collateral.  Proceeds from the sale of the Collateral or
any part thereof shall be applied by the MSO in the following order:

            A. To the payment of the costs and expenses of  collection  incurred
      by the MSO, including,  without limitation,  attorneys' fees and all other
      reasonable  expenses,  liabilities  and  costs  incurred  by  the  MSO  in
      connection therewith;

                                       36
<PAGE>

            B. To the  payment  of the whole  amount  then  owing and unpaid for
      advances and/or Management Fees;

            C. To the  payment  in full of all other  Obligations  of the New PC
      under the Agreement; and

            D. To the payment to the New PC of any surplus then  remaining  from
      such proceeds.

      7. Extension of Agreement.  No renewal or extension of the  Agreement,  no
release  or  surrender  of  any  Collateral  given  as  security  in  connection
therewith,  and no delay in  enforcement  thereof or in exercising  any right or
power with respect  thereto or hereunder shall affect the rights of the MSO with
respect to the Collateral or any part thereof.

      8. Notices.  Any notice to be given  pursuant to this  Agreement  shall be
deemed  effective  the same day when  such  notice  is given  personally,  or by

                                    EXHIBIT E


                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A. Method of Invoking ADR Procedures

      1. These  procedures  may be invoked  by any party to an  agreement  which
incorporates  these  procedures  by  giving  written  notice to the other of the
dispute  and   designating  a  person  with   decision-making   authority   (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required  to respond to the  disputing  party's  notice
within five (5) business days by designating in writing its own  representative.
A party may choose  more than one person to  represent  it. If a party  appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

      2. The parties,  each acting through its  representative,  shall meet at a
mutually  acceptable  time  and  place  within  five  business  days  after  the
non-disputing party designates its representative to the other. At that meeting,
the  parties  shall  attempt  in good faith to  negotiate  a  resolution  of the
dispute,  or  failing  that,  to agree on a method  for  resolving  the claim or
dispute.

      3. If,  within ten (10)  business  days after the first  meeting or within
such longer period of time as the parties may mutually  agree,  the parties have
not succeeded in negotiating a resolution of the claim or dispute or agreeing on
a dispute  resolution  mechanism,  they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

      4. The parties  will  jointly  appoint a mutually  acceptable  mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above,  then the parties  shall select a neutral third party from
the Center for Public Resources,  New York, New York ("CPR") Panels of Neutrals,
with the  assistance  of CPR,  unless the parties  agree  otherwise in finding a
mutually acceptable mediator.

      5. The New PC and the MSO shall each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR.

      6. The parties  agree to  participate  in good faith in the  mediation and
negotiations  related thereto for a period of thirty (30) days from  appointment
of a mediator by any of the parties or the CPR.


B. Mediation procedures

      1. The mediator shall be neutral and impartial.

                                       40
<PAGE>

      2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.

            (a) The  mediator is free to meet and  communicate  separately  with
      each party.

            (b) The mediator  will decide when to hold joint  meetings  with the
      parties and when to hold separate meetings. There shall be no stenographic
      record of any meeting. Formal rules of evidence will not apply.

            (c) The mediator  may request that there be no direct  communication
      between the parties or between their attorneys  without the concurrence of
      the mediator.

      3. Each party may be  represented  by more than one person,  e.g.,  one or
more of its  officers  and an  attorney.  Each party will have a  representative
fully authorized to negotiate a settlement of the dispute present.

      4. The process will be conducted expeditiously.

      5. The mediator will not transmit  information  received from any party to
another  party or any  third  person  unless  authorized  to do so by the  party
transmitting the information.

      6. The entire process is  confidential.  The parties and the mediator will
not disclose information  regarding the process,  including settlement terms, to
third persons,  unless the parties otherwise agree. The process shall be treated
as a compromise  negotiation  for purposes of the Federal  Rules of Evidence and
state rules of evidence.

      7. The parties will refrain from pursuing  administrative  and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

      8. Unless all parties and the mediator otherwise agree in writing,

            (a) The mediator will be  disqualified  as a witness,  consultant or
      expert in any  pending  or  future  investigation,  action  or  proceeding
      relating  to  the  subject   matter  of  the  mediation   (including   any
      investigation,  action or proceeding  which involves  persons not party to
      this mediation); and

            (b) The mediator and any documents and information in the mediator's
      possession  will not be  subpoenaed in any such  investigation,  action or
      proceeding,  and all parties  will oppose any effort to have the  mediator
      and documents subpoenaed.

      9. If the dispute goes into  arbitration,  the mediator shall not serve as
an arbitrator, unless the

                                       41
<PAGE>

parties and the mediator otherwise agree in writing.

      10. The mediator,  if a lawyer, may freely express views to the parties on
the legal issues of the dispute.

      11. The mediator shall not be liable for any act or omission in connection
with the mediation.

      12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons,  (ii) if the mediator believes that a party
is not acting in good faith,  or (iii) if the  mediator  concludes  that further
mediation efforts would not be useful.

C. Binding Arbitration

      If the parties do not resolve the  dispute  through  mediation  within the
period provided in Part A above,  the parties shall submit the matter to binding
arbitration  in Boston,  Massachusetts  before a qualified  sole  arbitrator  in
accordance with the then current CPR Rules for  Non-Administered  Arbitration of
Business  Disputes.  The sole  arbitrator  shall be agreed  upon by the  parties
within  twenty  (20) days  after  either  party  elects  to submit  any issue to
arbitration or, failing that,  shall be selected by CPR. A qualified  arbitrator
is one who is familiar  with the  principal  subject  matter of the issues to be
arbitrated  such as by way of example,  healthcare  services  industry  matters,
management  consulting  services  generally  or business  law/corporate  matters
generally.  Judgment upon the award rendered by the arbitrator may be entered in
any court having  jurisdiction.  The arbitrator  shall not have the authority to
award multiple, punitive or consequential damages under any circumstances.

                          MANAGEMENT SERVICES AGREEMENT

      THIS  AGREEMENT  is made  effective  as of this _____ day of  ___________,
1997, by and between ____________________, Inc., a professional corporation (the
"New PC")  incorporated  under the laws of the State of Colorado (the  "State"),
and OMEGA  Orthodontics of Colorado Springs,  Inc., a Delaware  corporation (the
"MSO"), and OMEGA ORTHODONTICS, INC., a Delaware corporation ("OMEGA").

      WHEREAS, OMEGA provides professional  management and marketing services to
orthodontic  practices in the United States,  which services  include  providing
practice management  systems,  office space,  equipment,  furnishings and active
administrative  personnel  necessary for the operation of orthodontic  practices
and are provided directly or indirectly through management service organizations
such as the MSO;

      WHEREAS,  OMEGA and Theodore G. Saydyk,  Jr., D.D.S. ("Dr. Saydyk") who is
duly  licensed  to practice  orthodontics  in the State have  entered  into that
certain Affiliation Agreement and Agreement and Plan of Merger (the "Affiliation
Agreement")  dated as of ________,  1997,  pursuant to which Theodore G. Saydyk,
Jr., D.D.S., P.C., a Colorado  professional  corporation owned by Dr. Saydyk was
merged into and with the MSO, a wholly-owned  subsidiary of OMEGA,  with the MSO
being the surviving corporation;

      WHEREAS, the New PC owns and operates an orthodontic practice with offices
located in the facilities  identified in Exhibit A (the  "Orthodontic  Offices")
and furnishes orthodontic care to the general public through the services of Dr.
Saydyk and any and all other orthodontists who are or become affiliated with the
New PC as of or following the date and who are or become  subsequently  named on
Schedule  1  hereto  (individually,  an  "Orthodontist"  and  collectively,  the
"Orthodontists");

      WHEREAS, the MSO was formed and acquired to provide equipment,  facilities
and personnel to, and to manage the non-orthodontic business affairs of, the New
PC;

      WHEREAS,  the MSO's  services are designed to improve the  efficiency  and
profitability  of the New PC while  enhancing  the ability of Dr. Saydyk and the
Orthodontists (if any) to render quality orthodontic care to the patients of the
New PC;

      WHEREAS,  the New PC wishes to retain the MSO to perform the functions and
to provide the  services  described  in this  Agreement  to assist the New PC to
achieve the above goals.

      NOW,  THEREFORE,  IT IS AGREED that the MSO shall perform  managerial  and
administrative  services for the New PC and provide office space and orthodontic
facilities  appropriate  for  rendering  general  orthodontic  treatment  at the
Orthodontic Offices upon the following terms and conditions:


                                    ARTICLE 1
                                      TERM



                                    
<PAGE>

      1.1 The initial term of this  Agreement  shall  commence on the date first
above  written  and  continue  for a period of twenty  (20) years (the  "Initial
Term"),  subject,  however, to earlier termination in accordance with Article 10
hereof.  This Agreement  shall continue for two separate and successive ten year
periods  (each a "Renewal  Term" and  collectively  with the Initial  Term,  the
"Term")  unless the MSO otherwise  elects upon six months  written notice to the
New PC prior to  expiration  of the Initial Term or any then  effective  Renewal
Term.

                                    ARTICLE 2
                                DUTIES OF THE MSO

      2.1 General. The MSO shall provide the New PC with comprehensive  practice
management,  financial and marketing services,  and such facilities,  equipment,
and support  personnel as are  reasonably  required by the New PC to operate its
orthodontic  practice at the  Orthodontic  Offices,  as determined by the MSO in
consultation with the New PC. The New PC hereby appoints the MSO as the sole and
exclusive  business manager of the New PC and agrees that the MSO shall have all
power and authority reasonably necessary to manage the non-orthodontic  business
affairs  of the New PC and carry out the MSO's  orthodontic  duties  under  this
Agreement, subject to the requirements of the applicable provisions of State law
relating to the practice of orthodontics. The MSO may perform some or all of its
services at a location other than at the Orthodontic Offices.

      2.2 Orthodontic Office Services.  The MSO shall provide or arrange for the
provision of the office space and related  leasehold  improvements to constitute
the Orthodontic Offices and related fixtures, furniture, furnishings,  equipment
and related services (collectively, the "Orthodontic Office Services") described
in Schedule 2 hereto,  as such Schedule may be amended by the New PC and the MSO
from time to time. The MSO shall be responsible for all repairs, maintenance and
replacement of the Orthodontic  Offices  including such leasehold  improvements,
fixtures, furniture,  furnishings and equipment, except for repairs, maintenance
and replacement  necessitated by the negligence of the New PC, its employees and
agents (not including the MSO or its employees or agents).  The MSO shall, on an
ongoing  basis,  evaluate and consult with the New PC on the equipment  needs of
and the  efficiency  and  adequacy  of the  Orthodontic  Offices.  The MSO shall
provide   telephone,   facsimile   transmission,   printing,   duplicating   and
transcribing services as needed, as well as all laundry, linen and uniforms.

      2.3 Administrative Services.

      (a)  The MSO  shall  supply  secretarial,  reception,  maintenance,  front
office,  skilled assistants and other personnel,  except duly licensed "Practice
Providers," during normal office hours as reasonably requested by the New PC, to
enable the New PC to perform effectively orthodontic and treatment services. The
MSO shall be  responsible  for staff  scheduling,  provided,  however,  that all
Practice  Providers  including  orthodontic  assistants and hygienists  shall be
under the direct supervision of the New PC. The New PC shall have sole authority
to employ and terminate the employment of all Practice Providers.  All personnel
placed in the Orthodontic Offices by the MSO shall be subject to the approval of
the New PC, which approval shall not be  unreasonably  withheld,  and the New PC
shall have the authority to instruct the MSO to terminate the employment of such
personnel for any lawful reason.  The MSO shall be responsible for all personnel
wages,

                                       2

<PAGE>

withholding,  fringe benefits,  bonuses and workers'  compensation  insurance in
connection  with its employees;  provided,  however,  that the New PC is in full
compliance with the compensation provisions of this Agreement.

      (b) "Practice  Providers" shall mean the individuals who are duly licensed
to practice dentistry and/or orthodontics in the State including Dr. Saydyk, the
Orthodontists (if any), any Temporary Orthodontist (as defined in (c) below) and
other  individuals  who are employees of the New PC or otherwise  under contract
with the New PC to provide dental or orthodontic,  hygienic or other  assistance
or services to patients of the New PC or otherwise required by applicable "Laws"
(as  defined in  Section  2.6  below) to be  employees  of the New PC to provide
services to patients of the Practice. A list of all Practice Providers and their
relationship  to the New PC is set  forth  as  Exhibit  B  attached  hereto  and
incorporated  herein by  reference.  Prior to making any  changes in the list of
Practice  Providers,  the New PC shall use its best  efforts to consult with the
MSO.  The New PC also shall use its best  efforts  to consult  with the MSO with
regard  to the  terms  of  contracts  entered  into  between  the New PC and the
Practice  Providers  and  the  terms  and  conditions  of  their  employment  or
engagement as independent contractors.

      (c)  "Temporary  Orthodontist"  shall  mean any one or more  Orthodontists
hired by the New PC to  substitute  for Dr.  Saydyk on a short-term or long-term
temporary  basis  due  to  Dr.   Saydyk's   Pre-Existing   Medical   Conditions.
"Pre-Existing  Medical Conditions" shall mean either or both of Dr. Saydyk's two
pre-existing  medical conditions  previously  disclosed to OMEGA. The New PC and
the MSO recognize that Dr. Saydyk's  Pre-Existing Medical Conditions may require
that a Temporary  Orthodontist be hired by the New PC on short notice,  and that
in such event, the MSO may not have prior notice of the Temporary Orthodontist's
hiring.  In an  effort  to  minimize  the  lack  of  notice  to the  MSO and the
disruption  to the New PC's  business,  the New PC and the MSO agree that on and
after the date of this  Agreement,  each shall use their best  efforts to locate
one or more orthodontists to be the Temporary Orthodontist,  if the need arises,
and the New PC agrees to contract with such Temporary Orthodontist. In the event
that Dr. Saydyk's  Pre-Existing Medical Conditions reoccur, and provided neither
the New PC nor Dr. Saydyk are  otherwise in default under this  Agreement or the
related agreements,  neither Dr. Saydyk nor the New PC shall be in default under
this  Agreement or related  agreements  provided that: (1) the New PC's business
for that  fiscal  year is not  materially  adversely  affected  by Dr.  Saydyk's
absence due to his Pre-Existing Medical Conditions; (2) beginning one week after
the  first  day  of  Dr.  Saydyk's  absence  due  to  the  Pre-Existing  Medical
Conditions,  at least ninety percent of his "Average  Weekly Hours",  as defined
below,  are covered by one or more Temporary  Orthodontists;  and (3) the New PC
and Dr.  Saydyk  each use their  best  efforts  to  locate  and hire one or more
Temporary Orthodontists to cover all of Dr. Saydyk's Average Weekly Hours during
the expected time of absence.  Notwithstanding  the foregoing  sentence,  if the
Pre-Existing  Medical  Conditions,  for a continuous period of three hundred and
sixty five (365) days,  or for more than a total of five hundred (500) days over
the period of two  calendar  years,  (i)  prevent  Dr.  Saydyk  from  practicing
orthodontics  for the New PC for the  Average  Weekly  Hours each week;  or (ii)
substantially   impair  the  New  PC's  or  Dr.  Saydyk's  ability  to  practice
orthodontics,  then the MSO shall be  entitled  to  exercise  its  rights  under
Section 5 of the Stock Put/Call  Option and Successor  Designation  Agreement by
and  between  the New PC,  Dr.  Saydyk,  OMEGA  and the MSO  dated of even  date
herewith. As used in this Agreement, "Average Weekly Hours" means a number which
is equal to: (a) the total  number of hours Dr.  Saydyk  practiced  orthodontics
over the  immediately  preceding one hundred  fifty-six  (156) weeks,  excluding
therefrom  those  weeks  where Dr.  Saydyk  was  absent  from the office for any
portion of the week for any reason other than vacations and holidays, divided by
the number of weeks Dr.  Saydyk  practiced  orthodontics  and was not absent for
such reasons.

                                       3

<PAGE>

      2.4 Business  Systems,  Procedures and Forms. In consultation with the New
PC, the MSO shall establish standardized business systems and procedures for the
New PC, including,  but not limited to, patient  scheduling  systems,  treatment
records  system,  financial  reporting and process  control  systems and patient
communication  management systems (the "OMEGA Patient  Scheduling  System") that
are designed to improve the New PC operating  efficiency.  The MSO shall analyze
such  information  on an ongoing  basis in order to advise the New PC on ways of
improving operating efficiencies. The MSO shall provide training to the staff of
the New PC in the  implementation  and operation of such  standardized  business
systems and procedures.  The MSO shall additionally  provide the New PC with and
train the New PC's staff in the use of standardized  clinical forms,  including,
without  limitation,  forms for patient evaluations and treatment plans. The New
PC expressly  acknowledges  and agrees that it shall have no property  rights in
the OMEGA Patient Scheduling System and the other foregoing systems,  procedures
and clinical forms, and further agrees that such systems,  procedures, and forms
shall be deemed to  constitute  Confidential  Information  within the meaning of
Section 3.8 hereof and be subject to the restrictions on the use, appropriation,
and reproduction of such Confidential Information provided for in Section 3.8.

      2.5 Purchasing,  Accounts Payable, Supplies and Inventory Control. The MSO
shall be  responsible  for and shall  establish  and  maintain  systems  for the
handling and  processing of all  purchasing  and payment  activities and for the
performance of all payroll and payroll  accounting  functions of the New PC. The
MSO shall order and purchase and maintain all inventory and orthodontic supplies
as reasonably  required by the New PC to enable the New PC to render orthodontic
care to its patients including,  without limitation,  all orthodontic appliances
and other supplies, laboratory supplies and sanitation supplies.

      2.6 Regulatory Compliance Services.  The MSO shall arrange for or cause to
be  rendered  to the New PC  such  business,  legal  and  regulatory  management
consultation and advice as may be reasonably required or requested by the New PC
and directly  related to the  operations  of the New PC or its  compliance  with
Federal, state or local laws, rules, regulations or interpretations governing or
applicable to the New PC (collectively, "Laws"); provided, however, that the MSO
shall not be  responsible  for any  services  related  to  malpractice  or other
professional  service claims or matters not directly related to the operation of
the New PC or its  compliance  with  Laws,  or for any  legal or tax  advice  or
services or personal  financial services to Dr. Saydyk and the Orthodontists (if
any) or any employee or agent of the New PC.

      2.7 Billing, Collection. The MSO shall be responsible for: (i) billing and
collecting payments for all orthodontic and other professional services rendered
by the New PC and the Practice  Providers,  with all such billing and collecting
to be done in the name of the New PC; (ii)  receiving  payments  from  patients,
insurance companies and all other third party payors; (iii) taking possession of
and  endorsing  in the  name  of the New PC any  notes,  checks,  money  orders,
insurance payments and other instruments  received in payment for services or of
accounts receivable; and (iv) settling and compromising claims and, where deemed
appropriate by the MSO and consented to (which consent shall not be unreasonably
withheld  or  delayed)  by the  Practice  Provider  rendering  the  professional
services which resulted in the applicable  accounts  receivable,  assigning such
accounts  receivable  to a  collection  agency or the bringing of a legal action
against a patient  or a payor on the New PC's  behalf.  In seeking  payments  on
behalf  of the New PC  hereunder,  the MSO  shall  act as the New PC's  agent in
billing and collecting professional fees, charges and other accounts owed to the
New PC and shall only bill 



                                       4
<PAGE>

under the New PC's provider number. In this regard,  the New PC appoints the MSO
for the Term of this  Agreement in accordance  with the provisions of Article 11
hereof as its true and lawful  attorney-in-fact for the purposes set forth above
in this  Section  2.7 and in  Section  2.8  below.  The MSO does  not  guarantee
collection and is not  responsible for any loss to the New PC as a result of any
inability to collect fees and charges.

      2.8 Disbursement of Funds.

      (a) All monies collected for the New PC by the MSO pursuant to Section 2.7
above shall be deposited  into an account (the "the New PC Account") with a bank
whose deposits are insured with the Federal  Deposit  Insurance  Corporation and
which  bank is  acceptable  to the MSO and the New PC (the  "Bank").  The New PC
Account  shall  contain  the  name of the New PC,  but the MSO  shall  make  all
disbursements  therefrom. The MSO shall account for all monies so disbursed from
the New PC Account.

      (b)  From  the  funds  collected  and  deposited  by the MSO in the New PC
Account,  the MSO  shall  make  for and on  behalf  of the New PC the  following
disbursements promptly, when payable:

            (1)  Compensation,  including  salaries,  benefits  and other direct
      costs payable to Dr. Saydyk and the  Orthodontists  (if any) and the other
      Practice   Providers  of  the  New  PC,  and  all  withholding  taxes  and
      assessments payable to Federal,  state and local governments in connection
      with the employment of such personnel; and

            (2) All  compensation  payable  to the MSO  pursuant  to  Article  6
      hereof.

      (c) In the  event  the funds in the New PC  Account  will,  at any time be
insufficient  to cover  the  current  portion  of the  foregoing  expenses  when
payable,  the  MSO may  advance  to the New PC the  necessary  funds  to pay the
current  portion of such expenses for the benefit of the New PC, which  advances
will be deemed to be loans to the New PC to be repaid without  interest from the
New PC Account at such times as there are  adequate  funds  therein or upon such
other  terms and at such  times as  agreed  to by the New PC and the MSO,  which
indebtedness shall not be deemed an MSO Expense for purposes of Section 2.9.

      2.9 MSO Expenses.  The MSO shall be responsible for the payment of all MSO
Expenses,   as  defined  below,  during  the  term  of  this  Agreement  without
reimbursement by the New PC, unless otherwise agreed to by the parties hereto.

      (a) "MSO  Expenses"  shall mean all operating and  non-operating  expenses
incurred in the operation of the New PC, including, without limitation:

            (1)  Salaries,  benefits and other direct costs of all  employees of
      the MSO  providing  services to the New PC hereunder  (but  excluding  Dr.
      Saydyk and all the Orthodontists (if any) and other Practice Providers);

            (2) Direct  costs of all  employees  or  consultants  of the MSO who
      provide services at the Orthodontic  Offices or in connection with the New
      PC required  for improved  clinic  performance,  



                                       5
<PAGE>

representative,  the MSO shall obtain on behalf of the New PC  information  with
regard to the ability of patients to pay for the  services to be rendered by the
New PC. The MSO shall collect all information and determine,  to the best of its
ability,  whether or not patients  can pay for services  rendered by the New PC,
either in cash or by  insurance.  Such  determination  shall be  subject  to the
reasonable  approval by the New PC, and as between  the New PC and the MSO,  the
New PC shall  bear the risk of claims by  potential  patients  who may be denied
credit.

the financial management of the New PC.

      2.12  Marketing.  The MSO shall  design and  execute a  marketing  plan to

with such marketing plan, the MSO shall advise Dr. Saydyk and the  Orthodontists
(if any) on  establishing  and  maintaining  a plan for  patients'  payments for

advertising by the orthodontic profession.

      2.13  Complaints.  The  MSO  shall  assist  the  New  PC in  handling  all
complaints,  grievances  and  disputes  involving  the New PC and  the  Practice

      2.14 Practice Laws.  Notwithstanding any provision in this Agreement,  the

<PAGE>

limitation,  the  performance  of any task or the  taking  of any  action  which

responsibility of the New PC).

      2.19  Practice  Transition  and  Associate  Selection.  Dr. Saydyk and the
Orthodontists  (if any) shall keep the MSO  informed of  retirement  goals on an
ongoing basis.  Upon request of the New PC, the MSO will conduct a search for an
appropriate  orthodontist  and  other  professionals  (collectively,   "Practice
Associates") for the purposes of accommodating practice growth,  reducing doctor
work schedule,  or planned retirement.  Such search shall include use by the MSO
of a national  journal  advertising  program and networking in the profession to
locate  appropriate  Practice  Associates.  The MSO estimates that it could take
approximately two years for such a search.

The  MSO  will  provide  screening  of all  applicants  and  will  then  present
appropriate  applicants  for final  selection by the New PC. The New PC shall be
responsible for interviewing and selecting each Practice Associate.

After the Practice  Associate(s)  is (are)  selected by the New PC, the MSO will
assist  the New PC with a trial  plan of  approximately  six  months for the new
Practice  Associate(s).  It is understood  that at the end of this period either
the New PC or the new Practice  Associate may terminate  the  relationship.  All
such Practice  Associates  recruited by the MSO as may be accepted by the New PC
shall be employees of the Practice (if so employed)  and not of the MSO. The MSO
will confer with the New PC on an appropriate salary/work-in arrangement for the
new Practice Associate and the final arrangements shall be determined by the New
PC.

                              DUTIES OF THE NEW PC


      3.1  General The New PC shall be  responsible  for the  management  of its
practice and 



                                       8
<PAGE>

the Orthodontic  Office,  in accordance with the requirements of the Laws of the
State.

      3.2 Employment of the Orthodontists and Rendering of Patient Care. The New
PC shall be responsible for the employment and  professional  supervision of Dr.
Saydyk  and  all  Orthodontists  and  the  other  Practice   Providers  and  all
orthodontic  care rendered to patients  shall be rendered by Dr. Saydyk and such
Orthodontists.   Additionally,   the  New  PC  shall  be  responsible   for  the
professional  supervision of all other Practice  Providers in their rendering of
patient care.

      3.3 Professional Services. The New PC shall use and occupy the Orthodontic
Offices  designated  on  Schedule  2 hereof  exclusively  for the  practice  and
rendering of orthodontic services, and shall comply with all applicable Laws and
all standards of orthodontic  care. It is expressly  acknowledged by the parties
that the  orthodontic  practice  conducted at the  Orthodontic  Offices shall be
conducted  solely by Dr.  Saydyk and the  Orthodontists  and the other  Practice
Providers  acting  under the  supervision  and  control  of Dr.  Saydyk  and the
Orthodontists (if any), and no other  orthodontist  shall be permitted to use or
occupy the Orthodontic Offices.  The New PC shall provide professional  services
to patients hereunder in compliance at all times with ethical standards and Laws
applying to the orthodontic profession.  The New PC shall ensure that Dr. Saydyk
and each Orthodontist who provides  orthodontic services to patients is licensed
by the State. In the event that any disciplinary,  medical  malpractice or other
actions are initiated  against Dr. Saydyk or any  Orthodontist or other Practice
Provider,  the New PC shall  immediately  inform the MSO of such  action and the
underlying facts and circumstances subject to such confidentiality  agreement or
arrangements  as the New PC and the MSO shall mutually  determine at or prior to
the time of such disclosure. The New PC agrees to cooperate with and participate
in  quality  assurance/utilization  review  programs  established  by the MSO or
mandated by accreditation and licensure standards  applicable to the practice of
orthodontics.  Deficiencies discovered in the performance of any personnel or in
the quality of professional  services shall be reported  immediately to the MSO,
and  appropriate  steps  shall  be taken  by the New PC at once to  remedy  such
deficiencies.

      3.4 Records.  The New PC will keep or cause to be kept accurate,  complete
and timely  dental and other  records of all  patients.  The  management  of all
dental and patient  files and records  shall  comply  with all  applicable  Laws
regarding their confidentiality and retention and all files and records shall be
located so that they are readily  accessible for patient care,  consistent  with
ordinary  records  management  practices.  Such records  shall be  sufficient to
enable the MSO, on behalf of the New PC, to obtain  payments  for  services  and
related  charges and to facilitate  the delivery of quality  patient care by the
New PC.  Notwithstanding  the  foregoing,  patient  dental  records shall be and
remain the property of the New PC and the contents  thereof  shall be solely the
responsibility of the New PC.

      3.5 Professional  Expenses. The New PC shall be solely responsible for the
cost of professional  licensure fees and board certification fees, membership in
professional associations and continuing professional education incurred by each
Orthodontist  and other  Practice  Provider  employed  by the New PC. The New PC
shall ensure that Dr.  Saydyk and all the  Orthodontists  employed by the New PC
participate in such continuing education as is necessary for Dr. Saydyk and such
the Orthodontists to remain current.

      3.6 Professional Liability Insurance. The New PC shall provide, or arrange
for the  provision  of,  and  maintain  throughout  the Term of this  Agreement,
professional  liability  insurance coverage in 



                                       9
<PAGE>

accordance  with the  provisions  of  Article  9 hereof.  The New PC shall  also
cooperate  in any  programs  recommended  by the MSO to assure  that each of its
Orthodontists  is  insurable,   and  that  Dr.  Saydyk  and  each   Orthodontist
participates in an on-going risk management program.

      3.7 Employment  Agreement.  The parties  recognize that the services to be
provided  by the  MSO  are  feasible  only  if the  New PC  operates  an  active
orthodontic  practice to which it, Dr. Saydyk and each  Orthodontist  associated
with the New PC devote  their full time and  attention,  unless  other  specific
provisions  are made in writing and mutually  agreed upon by the MSO and New PC.
The New PC will cause Dr. Saydyk and each individual Orthodontist,  other than a
Temporary Orthodontist,  who now is or hereafter becomes affiliated with the New
PC to enter into a written  employment  agreement (the  "Employment  Agreement")
satisfactory  in form and substance to the MSO,  pursuant to which Dr. Saydyk or
the Orthodontist shall agree not to establish, operate or provide orthodontic or
dental  services,  without the prior written  consent of both the New PC and the
MSO, at any office or facility other than the Orthodontic  Office.  In addition,
such  Employment  Agreement  shall  provide  by its own  terms or by a  separate
agreement that if Dr. Saydyk's or such Orthodontist's employment shall terminate
for any  reason  during  the Term of this  Agreement,  for a period of 24 months
after  the  termination  of  Dr.  Saydyk's  or  such  Orthodontist's  Employment
Agreement  with the New PC, Dr. Saydyk or such  Orthodontist  shall agree not to
establish,  operate or provide orthodontic or dental services, without the prior
written  consent  of both  the New PC and the MSO,  at any  office  practice  or
facility  whatsoever  providing services similar to those provided by the New PC
at any  orthodontic  office within a fifteen (15) mile radius.  Such  Employment
Agreement (or separate  agreement) shall also provide,  among other things, that
in the event of a breach of Dr. Saydyk's or the Orthodontist's  agreement not to
compete with the New PC provided for in such  Employment  Agreement (or separate
agreement),  the MSO shall be entitled to receive, in addition to other remedies
and not by way of an election  of  remedies,  liquidated  damages  equaling  the
greater of: (a) Dr. Saydyk's or such Orthodontist's  income, as shown on the W-2
form prepared by the New PC, for the most recent calendar year; or (b) $300,000.
Such  payment  shall  be made to the  MSO by the  New PC  immediately  following
receipt of the payment from Dr. Saydyk or the breaching  Orthodontist by the New
PC.  Each of the  MSO and  OMEGA  shall  be  expressly  named  as a  third-party
beneficiary  to such  agreements  between  the New PC and Dr.  Saydyk  and  each
Orthodontist  and the rights and  remedies  of the MSO and OMEGA  thereunder  or
otherwise in respect of the  restrictive  covenants set forth in such agreements
shall survive termination of this Agreement.

      3.8 Confidentiality. The New PC agrees and acknowledges that all materials
provided by the MSO to the New PC constitute "Confidential  Information" and are
disclosed in confidence and with the understanding that it constitutes  valuable
business information  developed by the MSO with the assistance of OMEGA at great
expenditures of time,  effort and money. The New PC further agrees that it shall
not,  directly or indirectly,  without the express prior written  consent of the
MSO, use or disclose such Confidential Information for any purpose other than in
connection  with the  services  to be  rendered  hereunder.  The New PC  further
agrees:  (i) to keep strictly  confidential  and hold in trust all  Confidential
Information and not disclose such  Confidential  Information to any third party,
including its shareholders, directors, officers, affiliates, partners, employees
and  independent  contractors  without the express prior written  consent of the
MSO; and (ii) to impose this obligation of  confidentiality on its shareholders,
directors,   officers,   affiliates,   partners,   employees   and   independent
contractors.  The  New PC  acknowledges  that  the  disclosure  of  Confidential
Information  to it by the MSO is done in reliance upon its  representations  and
covenants in this Agreement. Upon expiration or termination of this Agreement by
either party for any reason whatsoever,  the New PC shall immediately return and
shall  cause  its  



                                       10
<PAGE>

shareholders,   directors,  officers,  affiliates,  partners,  shareholders  and
independent  contractors  to  immediately  return  to the MSO  all  Confidential
Information,  and the New PC will not, and will cause its affiliates,  partners,
employees and independent  contractors not to, thereafter use,  appropriate,  or
reproduce  such   Confidential   Information.   The  New  PC  further  expressly
acknowledges and agrees that any such use,  appropriation or reproduction of any
such  Confidential  Information by any of the foregoing  after the expiration or
termination of this  Agreement will result in irreparable  injury to the MSO and
OMEGA, that the remedy at law for the foregoing would be inadequate, and that in
the  event  of  any  such  use,  appropriation,  or  reproduction  of  any  such
Confidential  Information after the termination or expiration of this Agreement,
the MSO and OMEGA,  in addition to any other  remedies or damages  available  to
either or both of them,  shall be  entitled  to  injunctive  or other  equitable
relief without the necessity of proving actual damages but such rights to relief
shall not preclude the MSO and OMEGA from other  remedies which may be available
to either or both of them hereunder.


                                    ARTICLE 4
                 PROFESSIONAL SERVICES, CONTROL OF SOLICITATION,
              APPROVAL OF ADVERTISING MATERIAL AND NO RECIPROCATION


      4.1 A  fundamental  understanding  between the parties  hereto is that the
rendering of  orthodontic  services shall be separate and  independent  from the
provision of  administrative,  management and support services by the MSO. Thus,
the  New PC  shall  have  sole  and  absolute  control  of the  delivery  of all
professional  services  and  treatment  rendered to patients at the  Orthodontic
Offices.

      4.2 No employee or other representative of the MSO shall be engaged in, or
allowed to solicit patients on behalf of, the New PC, nor shall the MSO have any
control over the New PC's patients.

      4.3 No  advertising or promotional  materials,  or other  materials of any
nature,   including   billing  and  collection   forms,   reports,   agreements,
correspondence,  or similar materials,  used in connection with the New PC shall
be used or distributed without having first been approved by the New PC.

      4.4 The parties hereby  acknowledge and agree that the benefits  conferred
upon each of them hereunder  neither  require nor are in any way contingent upon
the  admission,  recommendation,  referral,  or any  other  arrangement  for the
provision  of any item or service  offered by the MSO to any patients of the New
PC or its shareholders,  officers, directors, employees,  contractors or agents,
nor are such benefits in any way contingent upon the recommendation, referral or
any other  arrangement  for the provision of any item or service  offered by the
New PC or any of its Practice Providers, employees, contractors or agents.

the following terms and conditions:

      (a) The MSO is the  lessee by  assignment  under  lease  for the  premises
occupied by the New PC  (collectively,  the  "Master  Lease") a copy of which is
attached hereto as Exhibit A and incorporated herein by this reference.  The New
PC hereby  acknowledges  that the premises  described under the Master Lease are
suitable for the New PC's  orthodontic  practice.  Based and contingent upon the
New PC's  promise to timely pay all  amounts due under this  Agreement,  the MSO
hereby  agrees to sublease the leased  premises to the New PC upon the following
terms and conditions:

            (i) This  sublease  between  the MSO and the New PC of the  premises
      shall be subject to all of the terms and  conditions  of the Master Lease.
      In the event of the  termination of the MSO's interest as lessee under the
      Master  Lease for any  reason,  then the  sublease  created  hereby  shall
      simultaneously terminate,  unless the New PC assumes the obligations under
      the Master Lease in question and the Lessor consents thereto.

            (ii) All of the terms and  conditions  contained in the Master Lease
      are incorporated herein as terms and conditions of the sublease (with each
      reference  therein to "Lessor" and  "Lessee," to be deemed to refer to the
      MSO and the New PC,  respectively)  and, along with the provisions of this
      Section 5.1(b) and Exhibit "A," shall be the complete terms and conditions
      of the sublease created hereby.

            (iii) Notwithstanding the foregoing,  as between the MSO and the New
      PC, the MSO shall  remain  responsible  for  meeting  the  obligations  of
      "Lessee" under the sections  entitled Rent,  Additional  Rent  Adjustment,
      Insurance  on Fixtures,  Liability  Insurance,  Repairs,  and Taxes of the
      Master Lease,  all of which  obligations  shall be considered MSO Expenses
      hereunder and the New PC shall have no monetary obligation in that regard.
      In  addition,  as between the MSO and the New PC, the MSO shall retain the
      right to exercise any options to purchase the  premises,  or other similar
      rights of ownership or  possession,  which may be granted under the Master
      Lease, and the New PC shall have no rights in that regard.

            (iv) In the event this  Agreement  is  terminated  according  to its
      terms, this sublease shall also terminate automatically.

            (v) If the  Master  Lease  contains  an  option  to renew  the terms
      thereof,  the MSO shall  notify  the New PC, at least 30 days prior to the
      expiration of the time for exercising such option,  of the MSO's intention
      to renew or not to renew such  term.  If the MSO  determines  not to renew
      such  term,  the  MSO  shall  provide  or  arrange  for the  provision  of
      comparable  office space (the  "Substitute  Orthodontic  Office") within a
      radius of 15 miles of the Orthodontic Office, which Substitute Orthodontic
      Office  shall be subject  to the  approval  of the New PC (which  approval
      shall not be unreasonably withheld or delayed).  The lease or sublease for
      such Substitute  Orthodontic  Office, as applicable,  shall be substituted
      for the lease  described  on  Exhibit A hereto and all  references  to the
      "Master Lease" shall 



                                       12

      thereafter  be  applicable  to the lease or  sublease  for the  Substitute
      Orthodontic Office for purposes of this Agreement, ab initio.

            (vi) The  Alternative  Dispute  Resolution  provisions  set forth in
      Article 14 of this Agreement shall not apply to any issues  concerning the
      Sub-Lease,  the New PC's  tenancy  or the MSO's  rights  and  remedies  as
      Sub-Lessor.

      5.2 The MSO  shall  provide  the New PC at the  Orthodontic  Offices  such
additional  leasehold  improvements,   fixtures,   furniture,   furnishings  and
equipment as may be mutually  agreed to with the New PC and reflected  from time

leasehold improvements,  fixtures, furniture, furnishings and equipment provided
hereunder shall be subject to the following conditions:

      (a)  Title  to all such  leasehold  improvements,  fixtures,  furnishings,

good condition as when received, normal wear and tear excepted.

      (b) The MSO shall be fully and  entirely  responsible  for all repairs and
maintenance of all such leasehold improvements, fixtures, furniture, furnishings
and equipment;  provided,  however,  that the New PC agrees that it will use its
best  efforts to prevent  damage,  excessive  wear,  and  breakdown  of all such
leasehold  improvements,  fixtures,  furniture,  furnishings and equipment,  and
shall advise the MSO of any and all needed repairs and equipment failures.

      (c) The  obligation  of the MSO to  provide  the  leasehold  improvements,
fixtures, furniture, furnishings and equipment stated herein shall be concurrent
and co-extensive with the Term of this Agreement.

OR SUPPLIES  PROVIDED OR LEASED OR SUBLEASED  PURSUANT TO THIS AGREEMENT FOR THE
CONDUCT OF AN ORTHODONTICS PRACTICE OR FOR ANY OTHER PARTICULAR PURPOSE.

                                    COMPENSATION


      As consideration  for the performance of all of its duties and obligations
as  provided  in this  Agreement,  including  but not  limited to, the costs and
expenses  associated  with  furnishing  the  services,  personnel,   facilities,
leasehold improvements, fixtures, furniture, furnishings, equipment, inventories
and supplies provided for herein, the MSO shall receive compensation in the form
of monthly  management fees (the  "Management  Fees") based upon a predetermined
percentage of the "Practice  Revenues",  as defined and determined in accordance
with the  provisions  set forth in Schedule 3 attached  hereto and  incorporated
herein by this reference,  as such Schedule may be amended by the New PC and the
MSO from time to time. It is acknowledged by and between the parties hereto that
the MSO and/or its  affiliates  has (have)  incurred  substantial  expenses  and
future  obligations  in  acquiring  the capital  stock of the MSO,  acquiring or
otherwise  establishing  the  Orthodontic  Offices,  establishing  its  systems,
including fees for consultants and other professionals,  interest expense, lease
obligations,  and costs of furnishing or refurbishing  the premises at which the
Orthodontic   Offices  are  located.   The  MSO  has  also  assumed  substantial
obligations associated with the continuing operation of the Orthodontic Offices,
including  those of  lessee,  obligor  and  guarantor  and  obligor  on loans to
establish and operate the Orthodontic  Offices. The parties,  therefore,  having
considered various  compensation  formulae,  acknowledge and agree that in order
for the MSO to  receive  a fair  and  reasonable  return  for its  expenses  and
obligations,  and a fair return for the lease of the premises and  equipment and
for providing the services contemplated hereunder,  that the agreed compensation
is not excessive.  The New PC acknowledges that the compensation  arrangement is
reasonable  under the  circumstances  noted herein and has executed an Affidavit
attesting  to this fact  which is  attached  hereto and  incorporated  herein as
Exhibit C. In consideration of the foregoing, the parties agree that the monthly
Management Fees payable to the MSO by the New PC for services  rendered pursuant
to this  Agreement  shall be reviewed and subject to  adjustment at the close of
each  year of the  Term of this  Agreement  based  upon  industry  standards  of
practice and the MSO's costs in performing the required services. If the parties
cannot agree within  thirty (30) days prior to the close of any such year on the
terms of any adjustment to the Management  Fees for the following year, then the
then existing  Management  Fees shall remain in effect.  The New PC specifically
agrees  that the MSO may defer  actual  receipt of its  Management  Fees  and/or
advance  monies for purposes of managing the New PC's cash flow, and the MSO may
repay itself such  advances or pay said deferred  Management  Fees when it deems
appropriate.

for the faithful and timely  performance  of all the covenants and conditions to
be  performed  by the New PC under this  Agreement,  the New PC hereby  pledges,
grants, bargains, assigns and transfers to the MSO a security interest, pursuant
to the Uniform  Commercial Code of the State, in and to all Practice Revenue and

MSO may perfect its interest in the Collateral.  The New PC expressly  agrees to

                     AUTHORIZED AGENT AND POWERS OF ATTORNEY

      The New PC hereby  designates  the MSO (and its  designees) its authorized
agent and lawful  attorney-in-fact for purposes of depositing  payments,  paying
accounts  payables,  signing  checks,  negotiating  and  signing  contracts  for
services or goods,  securing loans or incurring obligations on behalf of the New
PC; provided,  however, that all contracts or fees set for services on behalf of

Additionally, the New PC hereby irrevocably appoints the MSO (and its designees)
its  authorized  agent and  lawful  attorney-in-fact  to  collect  all bills and

statements,  security  agreements or other agreements,  the MSO is authorized as
the agent of the New PC to sign any such instruments.  The New PC may review all
deposits and expenses upon request.

Agreement or otherwise against the MSO for worker's  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 the New PC. Since  neither the New PC nor its  employees  are

requirement of any  governmental  agency,  and all such  withholding,  if any is
required, shall be the sole responsibility of the New PC.

      13.1 Access to Records.  From and after any termination,  each party shall
provide the other party with  reasonable  access to books and records then owned
by it to permit  such  requesting  party to satisfy  reporting  and  contractual
obligations which may be required of it.

      13.2 Patient Records. Upon termination of this Agreement, the New PC shall
retain all patient  dental  records  maintained  by the New PC or the MSO in the

PC,  personally or through Dr. Saydyk or any of its  Orthodontists  (if any) and
other Practice  Providers,  shall have complete control and supervision over the
professional  aspects of the New PC's practice,  as well as the provision of all
professional services,  including, without limitation, the selection of a course
of treatment for a patient,  the procedures or materials to be used as a part of
such course of  treatment,  and the manner in which such course of  treatment is
carried  out by the New PC. The New PC shall have sole  authority  to direct the
business, professional, and ethical aspects of the New PC. The MSO shall have no
authority,  directly or  indirectly,  to  perform,  and shall not  perform,  any
orthodontic  function,  or to influence or otherwise interfere with the exercise
of the New PC's professional judgment.  The MSO may, however,  advise the New PC

informally  by the  



                                       20
<PAGE>

parties,  any party may invoke the  procedures set forth in Exhibit E hereto and
the parties agree to use these procedures,  except paragraph (b) of this Section
14.1,  prior to any party pursuing other  available  remedies.  The parties will
meet and attempt in good faith to resolve any  controversy  or claim arising out
of or relating to this Agreement.

      (b) Notwithstanding anything in this Section 14.1 to the contrary:

            (i)  Nothing  in this  Section  14.1 shall  preclude  any party from
      seeking a preliminary injunction or other provisional relief, either prior
      to or  during  the  proceeding  provided  for in this  section,  if in its
      judgment  such  action  is  necessary  to avoid  irreparable  damage or to
      preserve the status quo.

            (ii) The  parties  shall  accept  as  correct,  final,  binding  and
      conclusive the  determination by the outside  accountants then employed by
      the MSO as to the  calculation of any and all Management  Fees owed by the
      New PC to the MSO hereunder,  and such determination  shall not be subject
      to the  provisions  of  this  Section  14.1.  Disputes  as to  the  proper
      interpretation  of the  provisions of this  Agreement  which  describe how
      those  amounts  are to be  calculated,  however,  shall be  subject to the
      provisions of this Section 14.1.

            (iii) Any  determination by either party not to renew this Agreement
      in accordance with the terms and provisions of this Agreement shall not be
      subject to the provisions for dispute resolution in this Section 14.1.

      14.2  Waiver of Jury.  With  respect to any  dispute  arising  under or in
connection  with this  Agreement  or any  related  agreement,  as to which legal
action  nevertheless  occurs, each party hereby irrevocably waives all rights it
may have to demand a jury trial.  This waiver is  knowingly,  intentionally  and
voluntarily  made by the  parties  and each  party  acknowledges  that no person
acting  on behalf of the  other  party  has made any  representation  of fact to
induce this  waiver of trial by jury or in any way  modified  or  nullified  its
effect.  The parties each further  acknowledge  that it has been represented (or
has had the  opportunity to be represented) in the signing of this Agreement and
in the making of this waiver by independent  legal counsel,  selected of its own
free will,  and that it has had the  opportunity  to discuss  this  waiver  with
counsel.  Each party further  acknowledges  that it has read and understands the
meaning and ramifications of this waiver provision.

the case may be) written approval;  provided,  however,  the foregoing shall not
apply to information which is required to be disclosed by Law, including federal
or state securities laws, or pursuant to court order.

      15.3 Contract Modifications for Prospective Legal Events. In the event any
state or  federal  Laws,  now  existing  or  enacted  or  promulgated  after the
effective  date of this  Agreement,  are  interpreted  by judicial  decision,  a
regulatory  agency  or legal  counsel  for both  parties  in such a manner as to
indicate that the structure of this  Agreement may be in violation of such Laws,
the New PC and the MSO shall amend this  Agreement as necessary.  To the maximum
extent possible,  any such amendment shall preserve the underlying  economic and
financial arrangements between the New PC and the MSO.

      15.4  Remedies  Cumulative.  No  remedy  set  forth in this  Agreement  or
otherwise conferred upon or reserved to any party shall be considered  exclusive
of any other  remedy  available  to any party,  but the same shall be  distinct,
separate  and  cumulative  and may be  exercised  from  time to time as often as
occasion may arise or as may be deemed expedient.

      15.5 No Obligation to Third Parties. None of the obligations and duties of
the MSO or the New PC under this Agreement  shall in any way or in any manner be
deemed to create  any  obligation  of the MSO or of the New PC to, or any rights
in, any person or entity not a party to this  Agreement  other than OMEGA  which
shall be deemed a party for limited purposes as set forth in this Agreement.

      15.6 Entire Agreement. This Agreement including the Schedules and Exhibits

between the parties concerning this subject matter, and supersedes all prior and
contemporaneous  agreements,  representations  and understandings of the parties
concerning the contents  hereof.  No supplement,  modification,  or amendment to
this Agreement shall be binding unless executed in writing by all of the parties
hereto,  except as otherwise provided herein. No waiver of any of the provisions
of this Agreement shall be deemed to constitute a waiver of any other provision,
whether  similar or not  similar,  nor shall any waiver  constitute a continuing
waiver.  No waiver  shall be  binding  unless  executed  in writing by the party
making the waiver.

      15.7  Assignment.  The  rights and the  duties of the  parties  under this
Agreement may not be assigned or transferred  without the prior written  consent
of the non-assigning  party,  which consent shall not be unreasonably  withheld;
provided,  however,  that the MSO shall be  permitted  to assign  its rights and
obligations  hereunder without the consent of the New PC to any person,  firm or
corporation  controlled by the MSO,  controlling the MSO or under common control
with the MSO.

      15.8  Attorneys'  Fees.  If any  mediation or  arbitration  or other legal
action or  proceeding  is  brought  to enforce  this  Agreement,  because of any
alleged  breach  hereof,  or for a  declaration  of any rights  and  obligations
hereunder,  the  prevailing  party in such mediation or  arbitration,  action or
proceeding  shall be entitled to recover its costs incurred  therein,  including
reasonable  attorneys'  fees, in addition to any other relief to which it may be
entitled,  all as determined  and awarded by the parties in such mediation or by
the arbitrator or court as part of its judgment or decision therein, as the case
may be.

      15.9 Governing  Law. This Agreement  shall be governed by and construed in
accordance with the laws of the State.  The parties  acknowledge that the MSO is
not  authorized or qualified to engage in any activity which may be construed or
deemed to constitute  the practice of dentistry or  orthodontics.  To the extent
any act or service  required of the MSO in this Agreement should be construed or
deemed,  by any  governmental  authority,  agency  or  court to  constitute  the
practice of dentistry or orthodontics, the performance of said act or service by
the MSO shall be deemed waived and forever  unenforceable  and the provisions of
Section 15.14 shall be applicable.

      15.10 Events  Excusing  Performance.  Neither party shall be liable to the
other party for failure to perform any of the  services  required  herein in the
event of strikes, lock-outs, calamities, acts of God, unavailability of supplies
or other  events over which that party has no control for so long as such events
continue, and for a reasonable period of time thereafter.

      15.11  Compliance with Applicable Laws. Both parties shall comply with all
applicable  Laws and  restrictions  imposed  thereunder  in the conduct of their
obligations under this Agreement.

      15.12 Language  Construction.  The parties acknowledge that each party and

      15.13  Amendments.  This  Agreement  may be  amended  only by the  written
consent of both parties.

      15.14  Severability.  In the event any provision of this Agreement is held
by a court of competent  jurisdiction  to be illegal or  unenforceable,  (i) the
parties  shall  amend  this  Agreement  in  order to carry  out the  intent  and
essential  business  purposes of this Agreement as closely  possible  within the
requirements of applicable  provisions of Law as determined by such a court, and
(ii) the remaining provisions of this Agreement shall continue in full force and
effect.

      15.15 No Waiver.  The waiver by either party to this  Agreement of any one
or more defaults, if any, on the part of the other party, shall not be construed
to operate as a waiver of the other or future defaults under this Agreement.

      15.16  Captions.  Captions to paragraphs in this Agreement are for ease of
reference, and shall not be considered an interpretation of the paragraph.

      15.17 Counterparts.  This Agreement may be executed  simultaneously in one

                                   SCHEDULE 3

                         COMPENSATION - MANAGEMENT FEES


      The MSO shall receive,  as compensation  for the performance of all of its
obligations and duties contained in the Agreement, monthly Management Fees in an
amount equal to Seventy-Five Percent (75%) of the Practice Revenues, and the New
PC shall be entitled to  Twenty-Five  Percent (25%) of such  Practice  Revenues,
except as the parties may otherwise  agree from time to time in writing.  At the
end of each twelve (12) month period  during the Term the MSO shall  provide the
New PC with an unaudited  internal  accounting of the MSO Expenses,  prepared in
accordance  with the  accrual  method  of  accounting.  If the MSO  Expenses  as
reflected in such  accounting as having been paid by the MSO are less than sixty
(60%) percent of the Practice Revenues for such twelve month period, fifty (50%)
percent  of such  difference  shall  be  returned  by the MSO to the New PC as a
profit incentive rebate (the "Rebate").  If the Agreement to which this Schedule
3 is attached is terminated or expires,  the foregoing  Management Fees shall be
payable to the MSO based on all  Practice  Revenue  collected  as of the date of
termination or expiration.

      Payment  to the MSO  shall be made in  monthly  installments  based on the
Practice Revenues realized by the MSO for services rendered  hereunder.  The MSO
shall  distribute the proceeds from the New PC Account and allocate the proceeds
between the MSO and the New PC as described  above, on or before the 15th day of
the succeeding  month.  In the event the 15th day falls on a weekend or holiday,
then said  distribution  shall be made on the next  business  day.  The  parties
hereto may agree to handle such matters in a different manner.

      For  purposes  of this  Agreement,  "Practice  Revenues"  shall mean gross
collections  of all  revenues  generated  by or on behalf of the New PC (whether
through subsidiaries or affiliates), including, but not limited to, all fees and
charges collected as a result of professional  orthodontic services furnished to
patients by the New PC and for any other  goods or services  sold or provided to
such patients.

AFFIDAVIT


      I, Theodore G. Saydyk, Jr., D.D.S., declare:

      I am an  orthodontist,  duly  licensed  in the  State  of  Colorado  and I
practice through a professional  corporation under the name  ______________ (the
"New PC").

      I have had substantial  experience in the practice of the Orthodontics and
in managing and operating an orthodontic office.

      In  the  course  of  operating   orthodontic   offices,  I  have  acquired
significant  knowledge as to the  overhead  costs  incurred  and gross  receipts
generated by similar types of orthodontic offices.  Further, I am fully aware of
the non-orthodontic, operational, accounting, billing, financing, management and
personnel requirements of an orthodontic office and the cost factors involved in
providing  such  management,   personnel,  accounting,  billing,  financing  and
operation.

      I  have  thoroughly   reviewed  the  Management  Services  Agreement  (the
"Agreement"),  which is effective as of ________________,  1997, between the New
PC and Omega  Orthodontics of Colorado Springs,  Inc. (the "MSO") concerning the
duties,  responsibilities and obligations  undertaken by the MSO in managing and
operating all non-orthodontic  aspects of the Orthodontic Office as contemplated
by the Agreement.

      I  have  reviewed  the  prior  operating   financial   statements  of  the
orthodontic office located at 1317 North Academy Boulevard,  Suite 203, Colorado
Springs,  Colorado  80909 and an operating  budget and  estimated  income of the
orthodontic  office,  which, in my opinion,  can reasonably be expected from the
operation of said office.

      In my  opinion,  based upon my  experience,  the  Management  Fees of ____
Percent (___%) of "Practice  Revenues" to be charged by the MSO as  contemplated
by the Agreement,  will afford it a reasonable but not excessive  return for its
services rendered and obligations incurred. In addition, the New PC ____ Percent
( %) of  "Practice  Revenues"  retained by the New PC, will  provide  reasonable
earnings for the performance of orthodontic services.

      I declare under  penalty of perjury that the  foregoing  statement is true
and correct to the best of my knowledge and belief.

      Executed at                          , ________ this day of       , 1997.




                                                 ______________________________

                               SECURITY AGREEMENT


      THIS  SECURITY  AGREEMENT  is  effective as of the ______ day of _________
1997, by  _____________________,  PC, a Colorado corporation (the "New PC"), and
Theodore G. Saydyk,  Jr., D.D.S. ("Dr. Saydyk") who is duly licensed to practice
orthodontics in the State and Omega  Orthodontics of Colorado  Springs,  Inc., a
Delaware corporation (the "MSO") with reference to the following facts:

      WHEREAS,  pursuant to a Management  Services  Agreement (the "Agreement"),
dated as of the date hereof,  between the New PC and the MSO, as  assurance  and
collateral  security for the payment of the monthly  Management Fees owed to the
MSO pursuant to the Agreement and any funds  advanced by the MSO to or on behalf
of the  New PC  pursuant  to the  Agreement  and  for the  faithful  and  timely
performance  of all the covenants  and  conditions to be performed by the New PC
under  the  Agreement  (collectively,  the  "Obligations")  the New PC agreed to
pledge,  grant,  bargain,  assign and  transfer to the MSO a security  interest,
pursuant to the Uniform  Commercial  Code of the State,  in and to all  Practice
Revenue and the accounts receivable of patients of the New PC, together with all
proceeds thereof (collectively, the "Collateral");

      WHEREAS,  the New PC is obligated as a condition to the MSO's  performance
under the Agreement to execute and deliver this Security Agreement;

      NOW, THEREFORE, in consideration of the foregoing and of the covenants and
agreements hereinafter set forth, the parties hereto agree as follows:

      1. Grant of Security Interest.  As and for collateral security for payment
by the New PC of the  Obligations  and any and all  amounts  payable  under this
Security Agreement (collectively,  the "Secured Obligations"), the New PC hereby
pledges, grants,  bargains,  assigns and transfers to the MSO, and grants to the
MSO a security interest in, the Collateral. Dr. Saydyk shall cause the New PC to
perform fully and on a timely basis all of the New PC's  obligations  under this
Security Agreement.  Notwithstanding the foregoing sentence, Dr. Saydyk shall be
released from the obligation to cause the New PC to perform the  obligations set
forth  in  the  preceding   sentence,   upon  the  execution  of  an  agreement,
satisfactory to the MSO, by an Designated  Successor to assume such obligations.
The MSO may at its option file a financing  statement  (Form  UCC-1) in order to
perfect its security interest hereunder.

      2. Representations and Warranties.  The New PC represents and warrants all
of the accounts  receivable  constituting a portion of the Collateral of the New
PC pledged to the MSO are and will be validly created obligations of each of the
obligors who incurred same for services actually rendered in the ordinary course
of business of the New PC. Further,  the New PC represents and warrants that the
Collateral is not subject to any lien, pledge,  charge,  encumbrance or security
interest or right or option on the part of any third person.

      3. Release of Security Interest. Upon the termination of the Agreement and
payment in full of the accrued  Management Fees thereunder and any and all other
Secured Obligations,  the MSO shall release its security interest hereunder, and
will deliver to the New PC any property forming part of the Collateral delivered



                                       35
<PAGE>

to the MSO and then held by the MSO hereunder.

      4.  Realization  of  Collateral.  The MSO shall have,  with respect to the
Collateral,  the rights and  obligations  of a secured  party  under the Uniform
Commercial  Code as adopted in the state of Colorado (the "State").  Such rights
shall include, without limitation, the following:

      A. The right, upon default,  to have the Collateral,  or any part thereof,
transferred to its own name or to the name of its nominee;

      B. The  right,  upon  default,  to sell,  assign or deliver as much of the
Collateral  as is  reasonably  necessary  to repay  the  defaulted  indebtedness
(together with expenses  attendant upon such sale and  repayment),  at public or
private  sale,  as the MSO may  elect,  either  for cash or on  credit,  without
assumption  of any  credit  risk and  without  demand or  advertisement  (unless
otherwise required by law).

      C.  The New PC  hereby  irrevocably  authorizes  the MSO to sign  and file
financing  statements naming the New PC as the debtor and the MSO as the secured
party, at any time with respect to any Collateral,  without the signature of the
New  PC.  The  New PC  hereby  irrevocably  appoints  the  MSO as the  New  PC's
attorney-in-fact,  with full  authority in the place and stead of the New PC and
in the name of the New PC,  from time to time in the MSO's  discretion,  to take
any action and to execute any  instrument  which the MSO may deem  necessary  or
advisable to accomplish the purposes hereof. The attorney-in-fact granted herein
is coupled with an interest and is  irrevocable.  Third parties and entities and
persons  not a party to this  Security  Agreement  are  entitled to rely on this
attorney-in-fact  and an affidavit of the MSO attesting thereto.  The acceptance
of this  appointment  by the MSO shall not  obligate  it to perform  any duty or
covenant  required  to be  performed  by the New PC  under or by  virtue  of the
Collateral. Notwithstanding the foregoing power of attorney, the New PC shall at
any  time  on the  request  of the  MSO,  sign  Financing  Statements,  security
agreements or other agreements with respect to any Collateral. Upon the New PC's
failure  to  sign  said  Financing  Statements,  security  agreements  or  other
agreements,  the MSO is  authorized  as the agent of the New PC to sign any such
instruments.  Upon the  request of the MSO,  the New PC agrees to pay all filing
fees and to  reimburse  the MSO on demand for all costs and expenses of any kind
(including,  without  limitation,  legal fees) incurred in any way in connection
with the Collateral.

      5.  Purchase  of  Collateral.  At any such  private or public  sale of the
Collateral  or  part  thereof,  the  MSO may  purchase  and pay for the  same by
cancellation of such portion of the Obligations, equal to the purchase price and
free of any  right  of  redemption  on the part of the New PC.  the MSO  agrees,
however,  that the New PC shall  have all  rights,  including  rights of notice,
provided by the  Uniform  Commercial  Code as adopted in the State.  In any case
where notice is required,  five days' notice shall be deemed reasonable  notice.
In the event of any sale  hereunder,  the MSO shall  apply the  proceeds  in the
order set forth  below in  Paragraph  6 hereof.  the MSO may have  resort to the
Collateral or any portion thereof with no requirements on the part of the MSO to
proceed first against any other person or property.

      6. Application of Collateral.  Proceeds from the sale of the Collateral or
any part thereof shall be applied by the MSO in the following order:



                                       36

and/or Management Fees;

      C. To the payment in full of all other Obligations of the New PC under the
Agreement; and

      D. To the payment to the New PC of any surplus  then  remaining  from such
proceeds.

      7. Extension of Agreement.  No renewal or extension of the  Agreement,  no
release  or  surrender  of  any  Collateral  given  as  security  in  connection
therewith,  and no delay in  enforcement  thereof or in exercising  any right or
power with respect  thereto or hereunder shall affect the rights of the MSO with
respect to the Collateral or any part thereof.

      8. Notices.  Any notice to be given  pursuant to this  Agreement  shall be
deemed  effective  the same day when  such  notice  is given  personally,  or by
telegram,  or  electronic  transmission  to the  President  of the party to whom

                                    EXHIBIT E


                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES

A.    Method of Invoking ADR Procedures


      1. These  procedures  may be invoked  by any party to an  agreement  which
incorporates  these  procedures  by  giving  written  notice to the other of the
dispute  and   designating  a  person  with   decision-making   authority   (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required  to respond to the  disputing  party's  notice
within five (5) business days by designating in writing its own  representative.
A party may choose  more than one person to  represent  it. If a party  appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

      2. The parties,  each acting through its  representative,  shall meet at a
mutually  acceptable  time  and  place  within  five  business  days  after  the
non-disputing party designates its representative to the other. At that meeting,
the  parties  shall  attempt  in good faith to  negotiate  a  resolution  of the
dispute,  or  failing  that,  to agree on a method  for  resolving  the claim or
dispute.

      3. If,  within ten (10)  business  days after the first  meeting or within
such longer period of time as the parties may mutually  agree,  the parties have
not succeeded in negotiating a resolution of the claim or dispute or agreeing on
a dispute  resolution  mechanism,  they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

      4. The parties  will  jointly  appoint a mutually  acceptable  mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above,  then the parties  shall select a neutral third party from
the Center for Public Resources,  New York, New York ("CPR") Panels of Neutrals,
with the  assistance  of CPR,  unless the parties  agree  otherwise in finding a
mutually acceptable mediator.

      5. The New PC and the MSO shall each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR.

      6. The parties  agree to  participate  in good faith in the  mediation and
negotiations  related thereto for a period of thirty (30) days from  appointment
of a mediator by any of the parties or the CPR.


B.    Mediation procedures

      1. The mediator shall be neutral and impartial.



                                       40
<PAGE>

      2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.

      (a)   The mediator is free to meet and  communicate  separately  with each
            party.

      (b)   The  mediator  will  decide  when to hold  joint  meetings  with the
            parties  and  when to hold  separate  meetings.  There  shall  be no
            stenographic  record of any meeting.  Formal rules of evidence  will
            not apply.

      (c)   The  mediator  may  request  that  there be no direct  communication
            between  the  parties  or  between  their   attorneys   without  the
            concurrence of the mediator.

      3. Each party may be  represented  by more than one person,  e.g.,  one or
more of its  officers  and an  attorney.  Each party will have a  representative
fully authorized to negotiate a settlement of the dispute present.

      4. The process will be conducted expeditiously.

      5. The mediator will not transmit  information  received from any party to
another  party or any  third  person  unless  authorized  to do so by the  party
transmitting the information.

      6. The entire process is  confidential.  The parties and the mediator will
not disclose information  regarding the process,  including settlement terms, to
third persons,  unless the parties otherwise agree. The process shall be treated
as a compromise  negotiation  for purposes of the Federal  Rules of Evidence and
state rules of evidence.

      7. The parties will refrain from pursuing  administrative  and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

      8. Unless all parties and the mediator otherwise agree in writing,

      (a)   The mediator will be disqualified as a witness, consultant or expert
            in  any  pending  or  future  investigation,  action  or  proceeding
            relating  to the  subject  matter of the  mediation  (including  any
            investigation, action or proceeding which involves persons not party
            to this mediation); and

      (b)   The mediator and any documents  and  information  in the  mediator's
            possession will not be subpoenaed in any such investigation,  action
            or  proceeding,  and all parties  will oppose any effort to have the
            mediator and documents subpoenaed.

      9. If the dispute goes into  arbitration,  the mediator shall not serve as
an arbitrator, unless the 


                                       41
<PAGE>

parties and the mediator otherwise agree in writing.

      10. The mediator,  if a lawyer, may freely express views to the parties on
the legal issues of the dispute.

      11. The mediator shall not be liable for any act or omission in connection
with the mediation.

      12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons,  (ii) if the mediator believes that a party
is not acting in good faith,  or (iii) if the  mediator  concludes  that further
mediation efforts would not be useful.


      C. Binding  Arbitration If the parties do not resolve the dispute  through
mediation  within the period provided in Part A above,  the parties shall submit
the  matter  to  binding  arbitration  before a  qualified  sole  arbitrator  in
accordance with the then current CPR Rules for  Non-Administered  Arbitration of
Business Disputes.  If the party initially raising the dispute to be resolved is
New PC or Dr. Saydyk,  the arbitration  shall be held in Boston,  Massachusetts,
and if the party  initially  raising  the  dispute to be  resolved is the MSO or
OMEGA, the arbitration  shall be held in Denver,  Colorado.  The sole arbitrator
shall be agreed upon by the parties  within  twenty (20) days after either party
elects to submit any issue to arbitration or, failing that, shall be selected by
CPR. A qualified  arbitrator is one who is familiar  with the principal  subject
matter of the  issues to be  arbitrated  such as by way of  example,  healthcare
services industry matters,  management consulting services generally or business
law/corporate  matters  generally.  Judgment  upon  the  award  rendered  by the
arbitrator may be entered in any court having jurisdiction. The arbitrator shall
not have the  authority to award  multiple,  punitive or  consequential  damages
under any circumstances.

     WHEREAS,  the New PC owns and operates an orthodontic practice with offices
located in the facilities  identified in Exhibit A (the  "Orthodontic  Offices")
and furnishes orthodontic care to the general public through the services of Dr.

     WHEREAS,  the MSO was formed and acquired to provide equipment,  facilities

Term.

                                    ARTICLE 2

consultation with the New PC. The New PC hereby appoints the MSO as the sole and
exclusive  business manager of the New PC and agrees that the MSO shall have all
power and authority reasonably necessary to manage the non-orthodontic  business
affairs  of the New PC and carry out the MSO's  orthodontic  duties  under  this
Agreement, subject to the requirements of the applicable provisions of State law
relating to the practice of orthodontics. The MSO may perform some or all of its

agents (not including the MSO or its employees or agents).  The MSO shall, on an
ongoing  basis,  evaluate and consult with the New PC on the equipment  needs of
and the  efficiency  and  adequacy  of the  Orthodontic  Offices.  The MSO shall

under the direct supervision of the New PC. The New PC shall have sole authority
to employ and terminate the employment of all Practice Providers.  All personnel
placed in the Orthodontic Offices by the MSO shall be subject to the approval of
the New PC, which approval shall not be  unreasonably  withheld,  and the New PC

compliance with the compensation provisions of this Agreement.

     (b) "Practice  Providers"  shall mean the individuals who are duly licensed
to practice dentistry and/or orthodontics in the State including Dr. Feldman and

hygienic or other  assistance or services to patients of the New PC or otherwise
required by applicable  "Laws" (as defined in Section 2.6 below) to be employees
of the New PC to provide  services to patients  of the  Practice.  A list of all
Practice  Providers and their relationship to the New PC is set forth as Exhibit
B attached  hereto and  incorporated  herein by  reference.  Prior to making any
changes in the list of Practice Providers, the New PC shall use its best efforts
to consult  with the MSO.  The New PC also shall use its best efforts to consult
with the MSO with regard to the terms of contracts  entered into between the New
PC and the Practice  Providers and the terms and conditions of their  employment
or engagement as independent contractors.

     2.4 Business  Systems,  Procedures and Forms. In consultation  with the New
PC, the MSO shall establish standardized business systems and procedures for the
New PC, including,  but not limited to, patient  scheduling  systems,  treatment
records  system,  financial  reporting and process  control  systems and patient
communication  management systems (the "OMEGA Patient  Scheduling  System") that
are designed to improve the New PC operating  efficiency.  The MSO shall analyze
such  information  on an ongoing  basis in order to advise the New PC on ways of
improving operating efficiencies. The MSO shall provide training to the staff of
the New PC in the  implementation  and operation of such  standardized  business
systems and procedures.  The MSO shall additionally  provide the New PC with and
train the New PC's staff in the use of standardized  clinical forms,  including,
without  limitation,  forms for patient evaluations and treatment plans. The New
PC expressly  acknowledges  and agrees that it shall have no property  rights in
the OMEGA Patient Scheduling System and the other foregoing systems,  procedures
and clinical forms, and further agrees that such systems,  procedures, and forms

Section 3.8 hereof and be subject to the restrictions on the use, appropriation,
and reproduction of such Confidential Information provided for in Section 3.8.

     2.5 Purchasing,  Accounts Payable,  Supplies and Inventory Control. The MSO

     2.6 Regulatory  Compliance Services.  The MSO shall arrange for or cause to
be  rendered  to the New PC  such  business,  legal  and  regulatory  management

Federal, state or local laws, rules, regulations or interpretations governing or
applicable to the New PC (collectively, "Laws"); provided, however, that the MSO
shall not be  responsible  for any  services  related  to  malpractice  or other
professional  service claims or matters not directly related to the operation of
the New PC or its  compliance  with  Laws,  or for any  legal or tax  advice  or
services or personal financial services to Dr. Feldman 



                                       3
<PAGE>



and the Orthodontists (if any) or any employee or agent of the New PC.

     2.7 Billing,  Collection. The MSO shall be responsible for: (i) billing and
collecting payments for all orthodontic and other professional services rendered
by the New PC and the Practice  Providers,  with all such billing and collecting

services which resulted in the applicable  accounts  receivable,  assigning such
accounts  receivable  to a  collection  agency or the bringing of a legal action
against a patient  or a payor on the New PC's  behalf.  In seeking  payments  on
behalf  of the New PC  hereunder,  the MSO  shall  act as the New PC's  agent in
billing and collecting professional fees, charges and other accounts owed to the
New PC and shall only bill under the New PC's provider  number.  In this regard,
the New PC appoints the MSO for the Term of this  Agreement in  accordance  with
the provisions of Article 11 hereof as its true and lawful  attorney-in-fact for
the purposes  set forth above in this Section 2.7 and in Section 2.8 below.  The
MSO does not guarantee collection and is not responsible for any loss to the New
PC as a result of any inability to collect fees and charges.

     2.8 Disbursement of Funds.

     (a) All monies  collected for the New PC by the MSO pursuant to Section 2.7
above shall be deposited  into an account (the "the New PC Account") with a bank
whose deposits are insured with the Federal  Deposit  Insurance  Corporation and
which  bank is  acceptable  to the MSO and the New PC (the  "Bank").  The New PC
Account  shall  contain  the  name of the New PC,  but the MSO  shall  make  all
disbursements  therefrom. The MSO shall account for all monies so disbursed from
the New PC Account.

     (b)  From  the  funds  collected  and  deposited  by the  MSO in the New PC
Account,  the MSO  shall  make  for and on  behalf  of the New PC the  following
disbursements promptly, when payable:

          (1) Compensation,  including salaries, benefits and other direct costs
     payable  to Dr.  Feldman  and the  Orthodontists  (if  any)  and the  other
     Practice Providers of the New PC, and all withholding taxes and assessments
     payable to Federal,  state and local  governments  in  connection  with the
     employment of such personnel; and

          (2) All compensation payable to the MSO pursuant to Article 6 hereof.

     (c) In the  event  the  funds in the New PC  Account  will,  at any time be
insufficient  to cover  the  current  portion  of the  foregoing  expenses  when
payable,  the  MSO may  advance  to the New PC the  necessary  funds  to pay the
current  portion of such expenses for the benefit of the New PC, which  advances
will be deemed to be loans to the New PC to be repaid without  interest from the
New PC Account at such times as there are  adequate  funds  therein or upon such
other  terms and at such  times as  agreed  to by the New PC and the MSO,  which
indebtedness shall not be deemed an MSO Expense for purposes of Section 2.9.

representative,  the MSO shall obtain on behalf of the New PC  information  with
regard to the ability of patients to pay for the  services to be rendered by the
New PC. The MSO shall collect all information and determine,  to the best of its
ability,  whether or not patients  can pay for services  rendered by the New PC,
either in cash or by  insurance.  Such  determination  shall be  subject  to the
reasonable  approval by the New PC, and as between  the New PC and the MSO,  the

the MSO. At the end of each fiscal year of the New PC, the MSO shall arrange for
a  financial  statement  with  respect to the New PC to be prepared by the MSO's
accountant.  At the New PC's request,  the MSO shall prepare reports  indicating
the gross revenues,  number of patients,  type of patients, and the activity and
the  productivity  of the New PC. The MSO shall  assist and advise the New PC in
the financial management of the New PC.

     2.12  Marketing.  The MSO shall  design  and  execute a  marketing  plan to

the New PC all brochures,  contracts,  and other materials reasonably related to
the  carrying  out  of the  business  purposes  of the  New  PC,  including  all
stationery,  printing and postage costs in connection  therewith.  In connection
with such marketing plan, the MSO shall advise Dr. Feldman and the Orthodontists
(if any) on  establishing  and  maintaining  a plan for  patients'  payments for

patients shall be made by the New PC and the Practice Providers.

     2.14 Practice Laws.  Notwithstanding  any provision in this Agreement,  the
MSO shall not take any action in  connection  with the  services  to be rendered
hereunder that violates any Law, including,  without limitation, the performance

Professions  Code  of  the  State  as it  relates  to  professional  orthodontic
practices.

     2.15 Monthly  Meetings.  The MSO shall  initiate  monthly or more  frequent

with workers' compensation,  unemployment  insurance,  social security and other
similar Laws with respect to the MSO's employees.

     2.18 Insurance. The MSO shall provide and pay for customary office property
damage and liability,  including business interruption insurance,  not including
professional  liability  insurance (which shall be and remain the responsibility
of the New PC).

     2.19 Practice  Transition  and  Associate  Selection.  Dr.  Feldman and the
Orthodontists  (if 



                                       7
<PAGE>



any) shall keep the MSO informed of retirement  goals on an ongoing basis.  Upon
request  of the New  PC,  the MSO  will  conduct  a  search  for an  appropriate
orthodontist and other professionals  (collectively,  "Practice Associates") for
the purposes of accommodating practice growth, reducing doctor work schedule, or
planned  retirement.  Such  search  shall  include  use by the MSO of a national
journal   advertising  program  and  networking  in  the  profession  to  locate
appropriate  Practice   Associates.   The  MSO  estimates  that  it  could  take
approximately two years for such a search.

The  MSO  will  provide  screening  of all  applicants  and  will  then  present
appropriate  applicants  for final  selection by the New PC. The New PC shall be
responsible for interviewing and selecting each Practice Associate.

After the Practice  Associate(s)  is (are)  selected by the New PC, the MSO will
assist  the New PC with a trial  plan of  approximately  six  months for the new
Practice  Associate(s).  It is understood  that at the end of this period either
the New PC or the new Practice  Associate may terminate  the  relationship.  All
such Practice  Associates  recruited by the MSO as may be accepted by the New PC
shall be employees of the Practice (if so employed)  and not of the MSO. The MSO
will confer with the New PC on an appropriate salary/work-in arrangement for the
new Practice Associate and the final arrangements shall be determined by the New
PC.

                              DUTIES OF THE NEW PC


     3.1 General.  The New PC shall be  responsible  for the  management  of its
practice and the Orthodontic  Office, in accordance with the requirements of the
Laws of the State.

     3.2 Employment of the  Orthodontists and Rendering of Patient Care. The New
PC shall be responsible for the employment and  professional  supervision of Dr.
Feldman  and  all  Orthodontists  and  the  other  Practice  Providers  and  all
orthodontic  care rendered to patients shall be rendered by Dr. Feldman and such
Orthodontists.   Additionally,   the  New  PC  shall  be  responsible   for  the
professional  supervision of all other Practice  Providers in their rendering of
patient care.

     3.3 Professional  Services. The New PC shall use and occupy the Orthodontic
Offices  designated  on  Schedule  2 hereof  exclusively  for the  practice  and
rendering of orthodontic services, and shall comply with all applicable Laws and
all standards of orthodontic  care. It is expressly  acknowledged by the parties
that the  orthodontic  practice  conducted at the  Orthodontic  Offices shall be
conducted  solely by Dr.  Feldman and the  Orthodontists  and the other Practice
Providers  acting  under the  supervision  and  control of Dr.  Feldman  and the
Orthodontists (if any), and no other  orthodontist  shall be permitted to use or
occupy the Orthodontic Offices.  The New PC shall provide professional  services
to patients hereunder in compliance at all times with ethical standards and Laws
applying to the orthodontic profession. The New PC shall ensure that Dr. Feldman
and each Orthodontist who provides  orthodontic services to patients is licensed
by the State. In the event that any disciplinary,  medical  malpractice or other
actions are initiated  against Dr. Feldman or any Orthodontist or other Practice
Provider,  the New PC shall  immediately  inform the MSO of such  action and the
underlying facts and circumstances subject to such confidentiality  agreement or
arrangements  as the New PC and 



                                       8
<PAGE>



the MSO shall mutually determine at or prior to the time of such disclosure. The
New PC agrees to cooperate with and participate in quality assurance/utilization
review  programs  established  by  the  MSO or  mandated  by  accreditation  and
licensure  standards  applicable to the practice of  orthodontics.  Deficiencies
discovered in the performance of any personnel or in the quality of professional
services shall be reported  immediately to the MSO, and appropriate  steps shall
be taken by the New PC at once to remedy such deficiencies.

     3.4 Records.  The New PC will keep or cause to be kept  accurate,  complete
and timely  dental and other  records of all  patients.  The  management  of all
dental and patient  files and records  shall  comply  with all  applicable  Laws
regarding their confidentiality and retention and all files and records shall be
located so that they are readily  accessible for patient care,  consistent  with
ordinary  records  management  practices.  Such records  shall be  sufficient to
enable the MSO, on behalf of the New PC, to obtain  payments  for  services  and
related  charges and to facilitate  the delivery of quality  patient care by the
New PC.  Notwithstanding  the  foregoing,  patient  dental  records shall be and
remain the property of the New PC and the contents  thereof  shall be solely the
responsibility of the New PC.

     3.5 Professional  Expenses.  The New PC shall be solely responsible for the
cost of professional  licensure fees and board certification fees, membership in
professional associations and continuing professional education incurred by each
Orthodontist and other Practice  Provider  employed by the New PC. The MSO shall
reimburse the New PC for such expenses in accordance  with the Approved  Budget.
The New PC shall ensure that Dr. Feldman and all the  Orthodontists  employed by
the New PC  participate  in such  continuing  education as is necessary  for Dr.
Feldman and such the Orthodontists to remain current.

     3.6 Professional Liability Insurance.  The New PC shall provide, or arrange
for the  provision  of,  and  maintain  throughout  the Term of this  Agreement,
professional  liability  insurance coverage in accordance with the provisions of
Article 9 hereof. The New PC shall also cooperate in any programs recommended by
the MSO to assure  that each of its  Orthodontists  is  insurable,  and that Dr.
Feldman  and each  Orthodontist  participates  in an  on-going  risk  management
program.

     3.7  Employment  Agreement.  The parties  recognize that the services to be
provided  by the  MSO  are  feasible  only  if the  New PC  operates  an  active
orthodontic  practice to which it, Dr. Feldman and each Orthodontist  associated
with the New PC devote  their full time and  attention,  unless  other  specific
provisions  are made in writing and mutually  agreed upon by the MSO and New PC.
The New PC will cause Dr. Feldman and each individual Orthodontist who now is or
hereafter becomes  affiliated with the New PC to enter into a written employment
agreement (the "Employment Agreement") satisfactory in form and substance to the
MSO,  pursuant  to which Dr.  Feldman  or the  Orthodontist  shall  agree not to
establish,  operate or provide orthodontic or dental services, without the prior
written  consent of both the New PC and the MSO, at any office or facility other
than the  Orthodontic  Office.  In addition,  such  Employment  Agreement  shall
provide by its own terms or by a separate  agreement  that if Dr.  Feldman's  or
such Orthodontist's employment shall terminate for any reason during the Term of
this Agreement, for a period of 24 months after the termination of Dr. Feldman's
or such Orthodontist's Employment Agreement with the New PC, Dr. Feldman or such
Orthodontist  shall agree not to establish,  operate or provide  orthodontic  or
dental  services,  without the prior written  consent of both the New PC and the
MSO, at any office practice or facility whatsoever providing services similar to
those  provided by the New PC at any  orthodontic  office  within a fifteen (15)
mile  radius.  Such  Employment  Agreement  (or separate  



                                       9
<PAGE>



agreement) shall also provide, among other things, that in the event of a breach
of Dr. Feldman's or the Orthodontist's  agreement not to compete with the New PC
provided for in such Employment Agreement (or separate agreement), the MSO shall
be  entitled to receive,  in  addition  to other  remedies  and not by way of an
election  of  remedies,  liquidated  damages  equaling  the  greater of: (a) Dr.
Feldman's or such  Orthodontist's  income,  as shown on the W-2 form prepared by
the New PC, for the most recent  calendar  year; or (b)  $300,000.  Such payment
shall  be made to the MSO by the New PC  immediately  following  receipt  of the
payment from Dr.  Feldman or the breaching  Orthodontist  by the New PC. Each of
the MSO and OMEGA shall be expressly named as a third-party  beneficiary to such
agreements  between  the New PC and Dr.  Feldman and each  Orthodontist  and the
rights and remedies of the MSO and OMEGA  thereunder  or otherwise in respect of
the restrictive covenants set forth in such agreements shall survive termination
of this Agreement.

     3.8 Confidentiality.  The New PC agrees and acknowledges that all materials
provided by the MSO to the New PC constitute "Confidential  Information" and are
disclosed in confidence and with the understanding that it constitutes  valuable
business information  developed by the MSO with the assistance of OMEGA at great
expenditures of time,  effort and money. The New PC further agrees that it shall
not,  directly or indirectly,  without the express prior written  consent of the
MSO, use or disclose such Confidential Information for any purpose other than in
connection  with the  services  to be  rendered  hereunder.  The New PC  further
agrees:  (i) to keep strictly  confidential  and hold in trust all  Confidential
Information and not disclose such  Confidential  Information to any third party,
including its shareholders, directors, officers, affiliates, partners, employees
and  independent  contractors  without the express prior written  consent of the
MSO; and (ii) to impose this obligation of  confidentiality on its shareholders,
directors,   officers,   affiliates,   partners,   employees   and   independent
contractors.  The  New PC  acknowledges  that  the  disclosure  of  Confidential
Information  to it by the MSO is done in reliance upon its  representations  and
covenants in this Agreement. Upon expiration or termination of this Agreement by
either party for any reason whatsoever,  the New PC shall immediately return and
shall  cause  its  shareholders,   directors,  officers,  affiliates,  partners,
shareholders  and independent  contractors to immediately  return to the MSO all
Confidential  Information,  and  the  New  PC  will  not,  and  will  cause  its
affiliates,  partners,  employees and independent contractors not to, thereafter
use, appropriate, or reproduce such Confidential Information. The New PC further
expressly   acknowledges  and  agrees  that  any  such  use,   appropriation  or
reproduction of any such Confidential  Information by any of the foregoing after
the  expiration or  termination  of this  Agreement  will result in  irreparable
injury to the MSO and OMEGA,  that the remedy at law for the foregoing  would be
inadequate,  and  that  in  the  event  of  any  such  use,  appropriation,   or
reproduction  of any such  Confidential  Information  after the  termination  or
expiration  of this  Agreement,  the MSO and  OMEGA,  in  addition  to any other
remedies or damages  available  to either or both of them,  shall be entitled to
injunctive or other  equitable  relief  without the necessity of proving  actual
damages  but such  rights to relief  shall not  preclude  the MSO and OMEGA from
other remedies which may be available to either or both of them hereunder.


                                    ARTICLE 4
                 PROFESSIONAL SERVICES, CONTROL OF SOLICITATION,
              APPROVAL OF ADVERTISING MATERIAL AND NO RECIPROCATION


     4.1 A  fundamental  understanding  between the  parties  hereto is that the
rendering of  



                                       10
<PAGE>



orthodontic  services  shall be separate and  independent  from the provision of
administrative,  management  and support  services by the MSO.  Thus, the New PC
shall  have  sole and  absolute  control  of the  delivery  of all  professional
services and treatment rendered to patients at the Orthodontic Offices.

     4.2 No employee or other  representative of the MSO shall be engaged in, or
allowed to solicit patients on behalf of, the New PC, nor shall the MSO have any
control over the New PC's patients.

     4.3 No  advertising  or promotional  materials,  or other  materials of any
nature,   including   billing  and  collection   forms,   reports,   agreements,
correspondence,  or similar materials,  used in connection with the New PC shall
be used or distributed without having first been approved by the New PC.

     4.4 The parties hereby  acknowledge  and agree that the benefits  conferred
upon each of them hereunder  neither  require nor are in any way contingent upon
the  admission,  recommendation,  referral,  or any  other  arrangement  for the
provision  of any item or service  offered by the MSO to any patients of the New
PC or its shareholders,  officers, directors, employees,  contractors or agents,
nor are such benefits in any way contingent upon the recommendation, referral or
any other  arrangement  for the provision of any item or service  offered by the
New PC or any of its Practice Providers, employees, contractors or agents.

                                    ARTICLE 5
                    LEASE OF OFFICE FACILITIES AND EQUIPMENT

     5.1 In  consideration  of the sums to be paid to the MSO under the terms of
this Agreement, the MSO hereby leases or sub-leases,  as applicable,  to the New
PC during the Term of this Agreement the Orthodontic  Offices, and the leasehold
improvements and fixtures, furniture and equipment at the Orthodontic Offices as
listed from time to time on Schedule 2 attached hereto and  incorporated  herein
by this reference, under the following terms and conditions:

     (a) The MSO is the  lessee  by  assignment  under  lease  for the  premises
occupied by the New PC  (collectively,  the  "Master  Lease") a copy of which is
attached hereto as Exhibit A and incorporated herein by this reference.  The New
PC hereby  acknowledges  that the premises  described under the Master Lease are
suitable for the New PC's  orthodontic  practice.  Based and contingent upon the
New PC's  promise to timely pay all  amounts due under this  Agreement,  the MSO
hereby  agrees to sublease the leased  premises to the New PC upon the following
terms and conditions:

          (i) This sublease between the MSO and the New PC of the premises shall
     be subject to all of the terms and  conditions of the Master Lease.  In the
     event of the  termination  of the MSO's interest as lessee under the Master
     Lease for any reason, then the sublease created hereby shall simultaneously
     terminate, unless the New PC assumes the obligations under the Master Lease
     in question and the Lessor consents thereto.

          (ii) All of the terms and conditions contained in the Master Lease are
     incorporated  herein as terms and  conditions  of the  sublease  (with each
     reference  therein to "Lessor"  and  "Lessee," to be deemed to refer to the
     MSO and the New PC,  respectively)  and,  along with the provisions 



                                       11
<PAGE>



     of this Section  5.1(b) and Exhibit  "A," shall be the  complete  terms and
     conditions of the sublease created hereby.

          (iii)  Notwithstanding  the foregoing,  as between the MSO and the New
     PC,  the MSO shall  remain  responsible  for  meeting  the  obligations  of
     "Lessee" under the sections  entitled  Rent,  Additional  Rent  Adjustment,
     Insurance  on  Fixtures,  Liability  Insurance,  Repairs,  and Taxes of the
     Master Lease,  all of which  obligations  shall be considered  MSO Expenses
     hereunder and the New PC shall have no monetary  obligation in that regard.
     In  addition,  as between the MSO and the New PC, the MSO shall  retain the
     right to exercise any options to purchase the  premises,  or other  similar
     rights of ownership or  possession,  which may be granted  under the Master
     Lease, and the New PC shall have no rights in that regard.

          (iv) In the event this Agreement is terminated according to its terms,
     this sublease shall also terminate automatically.

          (v) If the Master Lease contains an option to renew the terms thereof,
     the MSO shall  notify the New PC, at least 30 days prior to the  expiration
     of the time for exercising such option,  of the MSO's intention to renew or

good condition as when received, normal wear and tear excepted.

                                  COMPENSATION


     As  consideration  for the performance of all of its duties and obligations
as  provided  in this  Agreement,  including  but not  limited to, the costs and
expenses  associated  with  furnishing  the  services,  personnel,   facilities,
leasehold improvements, fixtures, furniture, furnishings, equipment, inventories
and supplies provided for herein, the MSO shall receive compensation in the form
of monthly  management fees (the  "Management  Fees") based upon a predetermined
percentage of the "Practice  Revenues",  as defined and determined in accordance
with the  provisions  set forth in Schedule 3 attached  hereto and  incorporated
herein by this reference,  as such Schedule may be amended by the New PC and the
MSO from time to time. It is acknowledged by and between the parties hereto that
the MSO and/or its  affiliates  has (have)  incurred  substantial  expenses  and
future  obligations  in  acquiring  the capital  stock of the MSO,  acquiring or
otherwise  establishing  the  Orthodontic  Offices,  establishing  its  systems,
including fees for consultants and other professionals,  interest expense, lease
obligations,  and costs of furnishing or refurbishing  the premises at which the
Orthodontic   Offices  are  located.   The  MSO  has  also  assumed  substantial
obligations associated with the continuing operation of the Orthodontic Offices,
including  those of  lessee,  obligor  and  guarantor  and  obligor  on loans to
establish and operate the Orthodontic  Offices. The parties,  therefore,  having
considered various  compensation  formulae,  acknowledge and agree that in order

obligations,  and a fair return for the lease of the premises and  equipment and
for providing the services 



                                       13

contemplated hereunder,  that the agreed compensation is not excessive.  The New
PC  acknowledges  that the  compensation  arrangement  is  reasonable  under the
circumstances  noted herein and has executed an Affidavit attesting to this fact
which is attached hereto and incorporated  herein as Exhibit C. In consideration
of the foregoing,  the parties agree that the monthly Management Fees payable to
the MSO by the New PC for services  rendered pursuant to this Agreement shall be
reviewed and subject to adjustment at the close of each year of the Term of this
Agreement  based upon  industry  standards  of  practice  and the MSO's costs in
performing the required services. If the parties cannot agree within thirty (30)
days prior to the close of any such year on the terms of any  adjustment  to the
Management Fees for the following  year, then the then existing  Management Fees
shall remain in effect.  The New PC  specifically  agrees that the MSO may defer
actual  receipt of its  Management  Fees and/or  advance  monies for purposes of
managing the New PC's cash flow,  and the MSO may repay itself such  advances or
pay said deferred Management Fees when it deems appropriate.

Affiliation  Agreement),  OMEGA hereby pledges,  grants,  bargains,  assigns and

shall at any  time,  on the  request  of the  MSO,  sign  financing  statements,
security agreements or other agreements necessary or advisable to accomplish the
purpose of this  Agreement.  Upon the New PC's  failure  to sign said  financing

required, shall be the sole responsibility of the New PC.

obligations which may be required of it.

     13.2 Patient Records. Upon termination of this Agreement,  the New PC shall
retain all patient  dental  records  maintained  by the New PC or the MSO in the

the professional  aspects of the New PC's practice,  as well as the provision of
all professional  services,  including,  without limitation,  the selection of a
course of treatment for a patient,  the  procedures or materials to be used as a
part of such  course  of  treatment,  and the  manner  in which  such  course of
treatment is carried out by the New PC. The New PC shall have sole  authority to
direct the business,  professional,  and ethical  aspects of the New PC. The MSO
shall have no  authority,  directly or  indirectly,  to  perform,  and shall not
perform, any orthodontic  function,  or to influence or otherwise interfere with

performance of orthodontic functions and the overall administrative and business
functioning of the New PC.

(b) of this Section 14.1, prior to any party pursuing other available  remedies.
The parties  will meet and attempt in good faith to resolve any  controversy  or
claim arising out of or relating to this Agreement.

     (b) Notwithstanding anything in this Section 14.1 to the contrary:

          (i) Nothing in this Section 14.1 shall preclude any party from seeking
     a preliminary  injunction or other provisional  relief,  either prior to or
     during the proceeding provided for in this section, if in its judgment such
     action is necessary to avoid  irreparable  damage or to preserve the status
     quo.

          (ii)  The  parties  shall  accept  as  correct,   final,  binding  and
     conclusive the  determination  by the outside  accountants then employed by
     the MSO as to the  calculation of any and all  Management  Fees owed by the
     New PC to the MSO hereunder, and such determination shall not be subject to
     the   provisions  of  this  Section   14.1.   Disputes  as  to  the  proper
     interpretation of the provisions of this Agreement which describe how those
     amounts are to be calculated,  however,  shall be subject to the provisions
     of this Section 14.1.

          (iii) Any determination by either party not to renew this Agreement in
     accordance  with the terms and  provisions of this  Agreement  shall not be
     subject to the provisions for dispute resolution in this Section 14.1.

     14.2  Waiver of Jury.  With  respect  to any  dispute  arising  under or in
connection  with this  Agreement  or any  related  agreement,  as to which legal
action  nevertheless  occurs, each party hereby irrevocably waives all rights it
may have to demand a jury trial.  This waiver is  knowingly,  intentionally  and
voluntarily  made by the  parties  and each  party  acknowledges  that no person
acting  on behalf of the  other  party  has made any  representation  of fact to
induce this  waiver of trial by jury or in any way  modified  or  nullified  its
effect.  The parties each further  acknowledge  that it has been represented (or
has had the  opportunity to be represented) in the signing of this Agreement and
in the making of this waiver by independent  legal counsel,  selected of its own
free will,  and that it has had the  opportunity  to discuss  this  waiver  with
counsel.  Each party further  acknowledges  that it has read and understands the
meaning and ramifications of this waiver provision.

     15.3 Contract  Modifications for Prospective Legal Events. In the event any
state or  federal  Laws,  now  existing  or  enacted  or  promulgated  after the
effective  date of this  Agreement,  are  interpreted  by judicial  decision,  a

                                       21
<PAGE>



but the same shall be  distinct,  separate and  cumulative  and may be exercised
from time to time as often as occasion may arise or as may be deemed expedient.

     15.5 No Obligation to Third Parties.  None of the obligations and duties of
the MSO or the New PC under this Agreement  shall in any way or in any manner be

shall be deemed a party for limited purposes as set forth in this Agreement.

     15.6 Entire Agreement.  This Agreement including the Schedules and Exhibits
hereto,  together  with the Stock  Put/Call  Option  and  Successor  Designation
Agreement of even date herewith and the Employment  Agreement(s)  (including the
related  non-competition  agreements  or  covenants),   constitutes  the  entire
agreement between the parties concerning this subject matter, and supersedes all
prior and contemporaneous agreements,  representations and understandings of the
parties  concerning  the  contents  hereof.  No  supplement,   modification,  or
amendment to this Agreement  shall be binding unless  executed in writing by all
of the parties hereto,  except as otherwise provided herein. No waiver of any of
the provisions of this  Agreement  shall be deemed to constitute a waiver of any
other provision, whether similar or not similar, nor shall any waiver constitute
a continuing  waiver.  No waiver shall be binding unless  executed in writing by
the party making the waiver.

     15.7  Assignment.  The  rights  and the  duties of the  parties  under this
Agreement may not be assigned or transferred  without the prior written  consent
of the non-assigning  party,  which consent shall not be unreasonably  withheld;
provided,  however,  that the MSO shall be  permitted  to assign  its rights and
obligations  hereunder without the consent of the New PC to any person,  firm or
corporation  controlled by the MSO,  controlling the MSO or under common control
with the MSO.

     15.8 Attorneys' Fees. If any mediation or arbitration or other legal action
or  proceeding  is brought to enforce  this  Agreement,  because of any  alleged
breach hereof, or for a declaration of any rights and obligations hereunder, the
prevailing party in such mediation or arbitration, action or proceeding shall be
entitled to recover its costs incurred therein,  including reasonable attorneys'
fees,  in  addition  to any  other  relief to which it may be  entitled,  all as
determined  and awarded by the parties in such mediation or by the arbitrator or
court as part of its judgment or decision therein, as the case may be.

     15.9 Governing  Law. This  Agreement  shall be governed by and construed in
accordance with the laws of the State.  The parties  acknowledge that the MSO is
not  authorized or qualified to engage in any activity which may be construed or
deemed to constitute  the practice of dentistry or  orthodontics.  To the extent
any act or service  required of the MSO in this Agreement should be construed or
deemed,  by any  governmental  authority,  agency  or  court to  constitute  the
practice of dentistry or orthodontics, the performance of said act or service by
the MSO shall be deemed waived and forever  unenforceable  and the provisions of
Section 15.14 shall be applicable.

     15.10 Events  Excusing  Performance.  Neither  party shall be liable to the
other party for failure to perform any of the  services  required  herein in the
event of strikes, lock-outs, calamities, acts of God, unavailability of supplies
or other  events over which that party has no control for so long as such events
continue, 



                                       22

applicable  Laws and  restrictions  imposed  thereunder  in the conduct of their
obligations under this Agreement.

     15.12 Language  Construction.  The parties  acknowledge that each party and
its counsel have reviewed and revised this Agreement and that the normal rule of
construction to the effect that any  ambiguities are to be resolved  against the
drafting party shall not be employed in the interpretation of this Agreement.

     15.13 Amendments. This Agreement may be amended only by the written consent
of both parties.

     15.14 Severability. In the event any provision of this Agreement is held by
a court of  competent  jurisdiction  to be  illegal  or  unenforceable,  (i) the
parties  shall  amend  this  Agreement  in  order to carry  out the  intent  and
essential  business  purposes of this Agreement as closely  possible  within the
requirements of applicable  provisions of Law as determined by such a court, and
(ii) the remaining provisions of this Agreement shall continue in full force and
effect.

     15.15 No Waiver. The waiver by either party to this Agreement of any one or
more defaults, if any, on the part of the other party, shall not be construed to
operate as a waiver of the other or future defaults under this Agreement.

     15.16  Captions.  Captions to paragraphs in this  Agreement are for ease of
reference, and shall not be considered an interpretation of the paragraph.

     15.17 Counterparts. This Agreement may be executed simultaneously in one or
more counterparts, each of which shall be deemed an original.

                                   SCHEDULE 3

                         COMPENSATION - MANAGEMENT FEES


     The MSO shall receive,  as  compensation  for the performance of all of its
obligations and duties contained in the Agreement, monthly Management Fees in an
amount equal to Sixty-Five Percent (65%) of the Practice  Revenues,  and the New
PC shall be entitled to  Thirty-Five  Percent (35%) of such  Practice  Revenues,
except as the parties may otherwise  agree from time to time in writing.  At the
end of each twelve (12) month period  during the Term the MSO shall  provide the
New PC with an unaudited  internal  accounting of the MSO Expenses,  prepared in
accordance  with the  accrual  method  of  accounting.  If the MSO  Expenses  as
reflected in such  accounting as having been paid by the MSO are less than fifty
(50%) percent of the Practice Revenues for such twelve month period, fifty (50%)
percent  of such  difference  shall  be  returned  by the MSO to the New PC as a
profit incentive rebate (the "Rebate").  If the Agreement to which this Schedule
3 is attached is terminated or expires,  the foregoing  Management Fees shall be
payable to the MSO based on all  Practice  Revenue  collected  as of the date of
termination or expiration.

     Payment  to the MSO  shall  be made in  monthly  installments  based on the
Practice Revenues realized by the MSO for services rendered  hereunder.  The MSO
shall  distribute the proceeds from the New PC Account and allocate the proceeds
between the MSO and the New PC as described  above, on or before the 15th day of
the succeeding  month.  In the event the 15th day falls on a weekend or holiday,
then said  distribution  shall be made on the next  business  day.  The  parties
hereto may agree to handle such matters in a different manner.

     For  purposes  of this  Agreement,  "Practice  Revenues"  shall  mean gross
collections  of all  revenues  generated  by or on behalf of the New PC (whether
through subsidiaries or affiliates), including, but not limited to, all fees and
charges collected as a result of professional  orthodontic services furnished to
patients by the New PC and for any other  goods or services  sold or provided to
such patients.

                                    AFFIDAVIT

     I, Scott E. Feldman, D.D.S., declare:

     I am an  orthodontist,  duly  licensed  in the  State of  California  and I
practice through a professional  corporation under the name  ______________ (the
"New PC").

     I have had substantial  experience in the practice of the  Orthodontics and
in managing and operating an orthodontic office.

     In the course of operating orthodontic offices, I have acquired significant
knowledge as to the overhead  costs  incurred  and gross  receipts  generated by
similar  types  of  orthodontic  offices.  Further,  I am  fully  aware  of  the
non-orthodontic,  operational,  accounting,  billing, financing,  management and
personnel requirements of an orthodontic office and the cost factors involved in
providing  such  management,   personnel,  accounting,  billing,  financing  and
operation.

     I  have  thoroughly   reviewed  the  Management   Services  Agreement  (the
"Agreement"),  which is effective as of ________________,  1997, between the New
PC and Omega  Orthodontics  of Woodland Hills,  Inc. (the "MSO")  concerning the
duties,  responsibilities and obligations  undertaken by the MSO in managing and
operating all non-orthodontic  aspects of the Orthodontic Office as contemplated
by the Agreement.

     I have reviewed the prior operating financial statements of the orthodontic
office  located at 6325  Topanga  Canyon  Boulevard,  No. 424,  Woodland  Hills,
California 91367 and an operating budget and estimated income of the orthodontic
office,  which, in my opinion,  can reasonably be expected from the operation of
said office.

     In my opinion, based upon my experience,  the Management Fees of Sixty Five
Percent (65%) of "Practice Revenues" to be charged by the MSO as contemplated by
the  Agreement,  will afford it a reasonable  but not  excessive  return for its
services rendered and obligations incurred. In addition,  the New PC Thirty Five
Percent  (35%) of  "Practice  Revenues"  retained  by the New PC,  will  provide
reasonable earnings for the performance of orthodontic services.

     I declare under penalty of perjury that the foregoing statement is true and
correct to the best of my knowledge and belief.

     Executed at  ___________,  ________  this ____ day of  ___________________,
1997.

                               SECURITY AGREEMENT


     THIS  SECURITY  AGREEMENT  is  effective  as of the ______ day of _________
1997, by _____________________, PC, a California corporation (the "New PC"), and
Scott E.  Feldman,  D.D.S.  ("Dr.  Feldman")  who is duly  licensed  to practice
orthodontics  in the State and Omega  Orthodontics  of Woodland  Hills,  Inc., a
Delaware corporation (the "MSO") with reference to the following facts:

     WHEREAS,  pursuant to a Management  Services  Agreement (the  "Agreement"),
dated as of the date hereof,  between the New PC and the MSO, as  assurance  and
collateral  security for the payment of the monthly  Management Fees owed to the
MSO pursuant to the Agreement and any funds  advanced by the MSO to or on behalf
of the  New PC  pursuant  to the  Agreement  and  for the  faithful  and  timely
performance  of all the covenants  and  conditions to be performed by the New PC
under  the  Agreement  (collectively,  the  "Obligations")  the New PC agreed to
pledge,  grant,  bargain,  assign and  transfer to the MSO a security  interest,
pursuant to the Uniform  Commercial  Code of the State,  in and to all  Practice
Revenue and the accounts receivable of patients of the New PC, together with all
proceeds thereof (collectively, the "Collateral");

     WHEREAS,  the New PC is obligated  as a condition to the MSO's  performance
under the Agreement to execute and deliver this Security Agreement;

     NOW, THEREFORE,  in consideration of the foregoing and of the covenants and
agreements hereinafter set forth, the parties hereto agree as follows:

     1. Grant of Security Interest.  As and for collateral  security for payment
by the New PC of the  Obligations  and any and all  amounts  payable  under this
Security Agreement (collectively,  the "Secured Obligations"), the New PC hereby
pledges, grants,  bargains,  assigns and transfers to the MSO, and grants to the
MSO a security  interest in, the Collateral.  Dr. Feldman shall cause the New PC
to perform  fully and on a timely  basis all of the New PC's  obligations  under
this Security  Agreement.  The MSO may at its option file a financing  statement
(Form UCC-1) in order to perfect its security interest hereunder.

     2.  Representations and Warranties.  The New PC represents and warrants all
of the accounts  receivable  constituting a portion of the Collateral of the New
PC pledged to the MSO are and will be validly created obligations of each of the
obligors who incurred same for services actually rendered in the ordinary course
of business of the New PC. Further,  the New PC represents and warrants that the
Collateral is not subject to any lien, pledge,  charge,  encumbrance or security
interest or right or option on the part of any third person.

     3. Release of Security Interest.  Upon the termination of the Agreement and
payment in full of the accrued  Management Fees thereunder and any and all other
Secured Obligations,  the MSO shall release its security interest hereunder, and
will deliver to the New PC any property forming part of the Collateral delivered
to the MSO and then held by the MSO hereunder.

     4.  Realization  of  Collateral.  The MSO shall have,  with  respect to the
Collateral,  the rights and  



                                       34
<PAGE>



obligations of a secured party under the Uniform  Commercial  Code as adopted in
the state of  California  (the  "State").  Such rights  shall  include,  without
limitation, the following:

     A. The right,  upon default,  to have the Collateral,  or any part thereof,
transferred to its own name or to the name of its nominee;

     B. The  right,  upon  default,  to sell,  assign or  deliver as much of the
Collateral  as is  reasonably  necessary  to repay  the  defaulted  indebtedness
(together with expenses  attendant upon such sale and  repayment),  at public or
private  sale,  as the MSO may  elect,  either  for cash or on  credit,  without
assumption  of any  credit  risk and  without  demand or  advertisement  (unless
otherwise required by law).

     C.  The New PC  hereby  irrevocably  authorizes  the MSO to sign  and  file
financing  statements naming the New PC as the debtor and the MSO as the secured
party, at any time with respect to any Collateral,  without the signature of the
New  PC.  The  New PC  hereby  irrevocably  appoints  the  MSO as the  New  PC's
attorney-in-fact,  with full  authority in the place and stead of the New PC and
in the name of the New PC,  from time to time in the MSO's  discretion,  to take
any action and to execute any  instrument  which the MSO may deem  necessary  or
advisable to accomplish the purposes hereof. The attorney-in-fact granted herein
is coupled with an interest and is  irrevocable.  Third parties and entities and
persons  not a party to this  Security  Agreement  are  entitled to rely on this
attorney-in-fact  and an affidavit of the MSO attesting thereto.  The acceptance
of this  appointment  by the MSO shall not  obligate  it to perform  any duty or
covenant  required  to be  performed  by the New PC  under or by  virtue  of the
Collateral. Notwithstanding the foregoing power of attorney, the New PC shall at
any  time  on the  request  of the  MSO,  sign  Financing  Statements,  security
agreements or other agreements with respect to any Collateral. Upon the New PC's
failure  to  sign  said  Financing  Statements,  security  agreements  or  other
agreements,  the MSO is  authorized  as the agent of the New PC to sign any such
instruments.  Upon the  request of the MSO,  the New PC agrees to pay all filing
fees and to  reimburse  the MSO on demand for all costs and expenses of any kind
(including,  without  limitation,  legal fees) incurred in any way in connection
with the Collateral.

     5.  Purchase  of  Collateral.  At any such  private  or public  sale of the
Collateral  or  part  thereof,  the  MSO may  purchase  and pay for the  same by
cancellation of such portion of the Obligations, equal to the purchase price and
free of any  right  of  redemption  on the part of the New PC.  the MSO  agrees,

     THIS  SECURITY  AGREEMENT  is  effective  as of the ______ day of _________

Feldman, D.D.S. ("Dr. Feldman") who is duly licensed to practice orthodontics in
the State, with reference to the following facts:

     WHEREAS, pursuant to an Affiliation Agreement (the "Affiliation Agreement")
dated  ________ __, 1997 by and between Dr. Scott E. Feldman  D.D.S.,  M.S. (the
"Orthodontic  Entity") and Dr. Feldman,  and the Management  Services  Agreement
(the "Agreement"),  dated as of the date hereof, between the New PC and the MSO,
OMEGA, as assurance and collateral  security for the payment of the monies owned
to  Dr.  Feldman  under  the  Purchase  Note  (as  defined  in  the  Affiliation
Agreement), (the "Obligations"),  OMEGA agreed to pledge, grant, bargain, assign
and  transfer  to Dr.  Feldman a  security  interest,  pursuant  to the  Uniform
Commercial  Code of the State, in and to all leasehold  improvements,  fixtures,
furnishings, furniture and equipment now or hereafter located at the Orthodontic
Offices (collectively, the "Office Collateral");

     WHEREAS,  OMEGA is obligated as a condition  to Dr.  Feldman's  performance
under the  Affilation  and the  Agreement to execute and deliver  this  Security
Agreement;

     NOW, THEREFORE,  in consideration of the foregoing and of the covenants and
agreements hereinafter set forth, the parties hereto agree as follows:

     1. Grant of Security Interest.  As and for collateral  security for payment
by OMEGA of the  Obligations and any and all amounts payable under this Security
Agreement  (collectively,  the "Secured  Obligations"),  OMEGA  hereby  pledges,
grants,  bargains,  assigns and  transfers to Dr.  Feldman a security  interest,
pursuant to the Uniform  Commercial  Code of the State,  in and to all leasehold
improvements,  fixtures,  furnishings,  furniture and equipment now or hereafter
located  at the  Orthodontic  Offices.  Dr.  Feldman  may at his  option  file a
financing  statement  (Form  UCC-1) in order to perfect  his  security  interest
hereunder.

     2.  Representations and Warranties.  OMEGA represents and warrants that the
Collateral is not subject to any lien, pledge,  charge,  encumbrance or security
interest or right or option on the part of any third person, other than right to
transfer the Collateral to the MSO.

     3. Release of Security Interest.  Upon the termination of the Agreement and
payment in full of the amounts due under the Purchase  Note,  Dr.  Feldman shall
release his security interest hereunder, and will deliver to OMEGA a release.

     4.  Realization of Collateral.  Dr. Feldman shall have, with respect to the
Collateral,  the rights and  obligations  of a secured  party  under the Uniform
Commercial Code as adopted in the state of California (the "State"). Such rights

transferred to its own name or to the name of its nominee;

<PAGE>



     B. The  right,  upon  default,  to sell,  assign or  deliver as much of the
Collateral  as is  reasonably  necessary  to repay  the  defaulted  indebtedness
(together with expenses  attendant upon such sale and  repayment),  at public or
private sale, as Dr.  Feldman may elect,  either for cash or on credit,  without
assumption  of any  credit  risk and  without  demand or  advertisement  (unless
otherwise required by law).

     C. OMEGA shall at any time on the request of Dr.  Feldman,  sign  Financing
Statements,  security  agreements  or  other  agreements  with  respect  to  any
Collateral.  Upon OMEGA's  failure to sign said Financing  Statements,  security
agreements or other  agreements,  Dr.  Feldman is authorized as the agent of the
OMEGA to sign any such  instruments.  Upon the  request  of Dr.  Feldman,  OMEGA
agrees to pay all filing  fees and to  reimburse  Dr.  Feldman on demand for all
costs and  expenses  of any kind  (including,  without  limitation,  legal fees)
incurred in any way in connection with the Collateral.

     5.  Purchase  of  Collateral.  At any such  private  or public  sale of the
Collateral or part thereof, the Dr. Feldman may purchase and pay for the same by
cancellation of such portion of the Obligations, equal to the purchase price and
free of any  right of  redemption  on the part of  OMEGA.  Dr.  Feldman  agrees,
however,  that the OMEGA  shall  have all  rights,  including  rights of notice,
provided by the  Uniform  Commercial  Code as adopted in the State.  In any case
where notice is required,  five days' notice shall be deemed reasonable  notice.
In the event of any sale hereunder,  Dr. Feldman shall apply the proceeds in the
order set forth below in Paragraph 6 hereof.  Dr. Feldman may have resort to the
Collateral  or any  portion  thereof  with no  requirements  on the  part of Dr.
Feldman to proceed first against any other person or property.

     6.  Application of Collateral.  Proceeds from the sale of the Collateral or
any part thereof shall be applied by Dr. Feldman in the following order:

     A. To the payment of the costs and expenses of  collection  incurred by Dr.
Feldman, including, without limitation, attorneys' fees and all other reasonable
expenses,  liabilities  and costs  incurred  by the Dr.f  Feldman in  connection
therewith;

     B. To the  payment of the whole  amount  then  owing and  unpaid  under the
Purchase Note;

     C. To the  payment  to  OMEGA  of any  surplus  then  remaining  from  such
proceeds.

     7.  Extension of Agreement.  No renewal or extension of the  Agreement,  no
release  or  surrender  of  any  Collateral  given  as  security  in  connection
therewith,  and no delay in  enforcement  thereof or in exercising  any right or
power with respect  thereto or hereunder  shall affect the rights of Dr. Feldman
with respect to the Collateral or any part thereof.

     8.  Notices.  Any notice to be given  pursuant to this  Agreement  shall be

EXHIBIT E


ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A.Method of Invoking ADR Procedures

1. These procedures may be invoked by any party to an agreement which
incorporates these procedures by giving written notice to the other of the
dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

2. The parties, each acting through its representative, shall meet at a
mutually acceptable time and place within five business days after the
non-disputing party designates its representative to the other. At that meeting,
the parties shall attempt in good faith to negotiate a resolution of the
dispute, or failing that, to agree on a method for resolving the claim or
dispute.

3. If, within ten (10) business days after the first meeting or within such
longer period of time as the parties may mutually agree, the parties have not
succeeded in negotiating a resolution of the claim or dispute or agreeing on a
dispute resolution mechanism, they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

4. The parties will jointly appoint a mutually acceptable mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above, then the parties shall select a neutral third party from
the Center for Public Resources, New York, New York ("CPR") Panels of Neutrals
or the American Arbitration Association ("AAA"), with the assistance of CPR or
AAA, unless the parties agree otherwise in finding a mutually acceptable
mediator.

5. The New PC and the MSO shall each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR or AAA.

6. The parties agree to participate in good faith in the mediation and
negotiations related thereto for a period of thirty (30) days from appointment
of a mediator by any of the parties or the CPR or AAA.


B. Mediation procedures



                                       44
<PAGE>



     1. The mediator shall be neutral and impartial.

     2. The mediator shall control the procedural aspects of the mediation.  The
parties will cooperate fully with the mediator.


          (a) The mediator is free to meet and communicate  separately with each
     party.

          (b) The  mediator  will  decide when to hold joint  meetings  with the
     parties and when to hold separate meetings.  There shall be no stenographic
     record of any meeting. Formal rules of evidence will not apply.

          (c) The  mediator  may request  that there be no direct  communication
     between the parties or between their  attorneys  without the concurrence of
     the mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its  officers and an attorney.  Each party will have a  representative  fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator  will not transmit  information  received from any party to
another  party or any  third  person  unless  authorized  to do so by the  party
transmitting the information.

     6. The entire  process is  confidential.  The parties and the mediator will
not disclose information  regarding the process,  including settlement terms, to
third persons,  unless the parties otherwise agree. The process shall be treated
as a compromise  negotiation  for purposes of the Federal  Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing  administrative  and/or  judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

          (a) The mediator  will be  disqualified  as a witness,  consultant  or
     expert  in any  pending  or  future  investigation,  action  or  proceeding
     relating  to  the  subject   matter  of  the   mediation   (including   any
     investigation,  action or proceeding  which  involves  persons not party to
     this mediation); and

          (b) The mediator and any documents and  information  in the mediator's
     possession  will not be  subpoenaed  in any such  investigation,  action or
     proceeding, and all parties will oppose any effort to have the mediator and
     documents subpoenaed.



                                       45
<PAGE>



     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.

     10. The mediator,  if a lawyer,  may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator  shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written  notice to the parties
(i) for overriding personal reasons,  (ii) if the mediator believes that a party
is not acting in good faith,  or (iii) if the  mediator  concludes  that further
mediation efforts would not be useful.

C. Binding Arbitration

     If the  parties do not resolve the  dispute  through  mediation  within the
period provided in Part A above,  the parties shall submit the matter to binding
arbitration  in Boston,  Massachusetts  before a qualified  sole  arbitrator  in
accordance with the then current CPR Rules for  Non-Administered  Arbitration of
Business  Disputes or comparable  AAA rules.  The  arbitration  shall be held in
Woodland  Hills,  California.  The sole  arbitrator  shall be agreed upon by the
parties within twenty (20) days after either party elects to submit any issue to
arbitration  or,  failing  that,  shall be  selected  by CPR or AAA. A qualified
arbitrator  is one who is  familiar  with the  principal  subject  matter of the
issues to be arbitrated such as by way of example,  healthcare services industry
matters,  management  consulting  services  generally or business  law/corporate
matters  generally.  Judgment upon the award  rendered by the  arbitrator may be
entered in any court  having  jurisdiction.  The  arbitrator  shall not have the
authority  to award  multiple,  punitive  or  consequential  damages  under  any
circumstances.

payable,  the  MSO may  advance  to the New PC the  necessary  funds  to pay the
current  portion of such expenses for the benefit of the New PC, which  advances
will be deemed to be loans to the New PC to be repaid without  interest from the
New PC Account at such times as there are  adequate  funds  therein or upon such
other  terms and at such  times as  agreed  to by the New PC and the MSO,  which

appropriate  orthodontist  and  other  professionals  (collectively,   "Practice
Associates") for the purposes of accommodating practice growth,  reducing doctor
work schedule,  or planned retirement.  Such search shall include use by the MSO
of a national  journal  advertising  program and networking in the profession to

responsible for interviewing and selecting each Practice Associate.

After the Practice  Associate(s)  is (are)  selected by the New PC, the MSO will
assist  the New PC with a trial  plan of  approximately  six  months for the new
Practice  Associate(s).  It is understood  that at the end of this period either
the New PC or the new Practice  Associate may terminate  the  relationship.  All
such Practice  Associates  recruited by the MSO as may be accepted by the New PC
shall be employees of the Practice (if so employed)  and not of the MSO. The MSO
will confer with the New PC on an appropriate salary/work-in arrangement for the
new Practice Associate and the final arrangements shall be determined by the New

final selection by the New PC;

     (c) The New PC shall be  responsible  for  interviewing  and selecting each
candidate to replace Dr. Zapalac from the  candidates  presented by the MSO and,
once a candidate is selected,  Dr. Zapalac shall use all  reasonable  efforts to
see that such candidate successfully completes a six month trial period with the
New PC; and

<PAGE>

     (d) It is understood  that at the end of this trial period,  either the New
PC or the candidate to replace Dr.  Zapalac may terminate the  relationship.  If
the  relationship  is  terminated,  the search  process  outlined in clauses (a)
through (d) of this Section 2.19 shall begin again. Any candidate to replace Dr.
Zapalac who is accepted by the New PC shall be an employee of the  Practice  (if
so  employed)  and not of the  MSO.  The MSO will  confer  with the New PC on an
appropriate   salary/work-in  arrangement  for  such  candidate  and  the  final
arrangements  shall be determined by the New PC and the  Orthodontists  (if any)
shall  keep the MSO  informed  of  retirement  goals on an ongoing  basis.  Upon
request  of the New  PC,  the MSO  will  conduct  a  search  for an  appropriate
orthodontist and other professionals  (collectively,  "Practice Associates") for
the purposes of accommodating practice growth, reducing doctor work schedule, or
planned  retirement.  Such  search  shall  include  use by the MSO of a national
journal   advertising  program  and  networking  in  the  profession  to  locate
appropriate  Practice   Associates.   The  MSO  estimates  that  it  could  take
approximately two years for such a search.

The  MSO  will  provide  screening  of all  applicants  and  will  then  present
appropriate  applicants  for final  selection by the New PC. The New PC shall be
responsible for interviewing and selecting each Practice Associate.

After the Practice  Associate(s)  is (are)  selected by the New PC, the MSO will
assist  the New PC with a trial  plan of  approximately  six  months for the new
Practice  Associate(s).  It is understood  that at the end of this period either
the New PC or the new Practice  Associate may terminate  the  relationship.  All
such Practice  Associates  recruited by the MSO as may be accepted by the New PC
shall be employees of the Practice (if so employed)  and not of the MSO. The MSO
will confer with the New PC on an appropriate salary/work-in arrangement for the

Zapalac  and the  Orthodontists  (if any),  and no other  orthodontist  shall be
permitted to use or occupy the  Orthodontic  Offices.  The New PC shall  provide
professional  services to patients  hereunder  in  compliance  at all times with
ethical  standards and Laws applying to the orthodontic  profession.  The New PC
shall ensure that Dr.  Zapalac and each  Orthodontist  who provides  orthodontic
services  to  patients  is  licensed  by  the  State.  In  the  event  that  any
disciplinary,  medical  malpractice  or other actions are initiated  against Dr.
Zapalac  or any  Orthodontist  or  other  Practice  Provider,  the New PC  shall
immediately  inform  the  MSO of  such  action  and  the  underlying  facts  and
circumstances  subject to such confidentiality  agreement or arrangements as the
New PC and the MSO  shall  mutually  determine  at or  prior to the time of such
disclosure.  The New PC agrees to  cooperate  with and  participate  in  quality
assurance/utilization  review  programs  established  by the MSO or  mandated by
accreditation   and   licensure   standards   applicable   to  the  practice  of
orthodontics.  Deficiencies discovered in the performance of any personnel or in
the quality of professional  services shall be reported  immediately to the MSO,
and  appropriate  steps  shall  be taken  by the New PC at once to  remedy  such
deficiencies.

     3.4 Records.  The New PC will keep or cause to be kept  accurate,  complete
and timely  dental and other  records of all  patients.  The  management  of all
dental and patient  files and records  shall  comply  with all  applicable  Laws
regarding their confidentiality and retention and all files and records shall be
located so that they are readily  accessible for patient care,  consistent  with
ordinary  records  management  practices.  Such records  shall be  sufficient to
enable the MSO, on behalf of the New PC, to obtain  payments  for  services  and
related  charges and to facilitate  the delivery of quality  patient care by the
New PC.  Notwithstanding  the  foregoing,  patient  dental  records shall be and
remain the property of the New PC and the contents  thereof  shall be solely the
responsibility of the New PC.

     3.5 Professional  Expenses.  The New PC shall be solely responsible for the
cost of professional  licensure fees and board certification fees, membership in
professional associations and continuing professional education incurred by each
Orthodontist  and other  Practice  Provider  employed  by the New PC. The New PC

for the  provision  of,  and  maintain  throughout  the Term of this  Agreement,
professional  liability  insurance coverage in accordance with the provisions of
Article 9 hereof. The New PC shall also cooperate in any programs recommended by
the MSO to assure  that each of its  Orthodontists  is  insurable,  and that Dr.
Zapalac  and each  Orthodontist  participates  in an  on-going  risk  management
program.

     3.7  Employment  Agreement.  The parties  recognize that the services to be
provided  by the  MSO  are  feasible  only  if the  New PC  operates  an  active
orthodontic  practice to which it, Dr. Zapalac and each Orthodontist  associated
with the New PC devote  their full time and  attention,  unless  other  specific
provisions  are made in writing and mutually  agreed upon by the MSO and New PC.
The New PC will cause Dr. Zapalac and each individual Orthodontist who now is or
hereafter becomes  affiliated with the New PC to enter into a written employment
agreement (the "Employment Agreement") satisfactory in form and substance to the
MSO and Dr.  Zapalac,  pursuant to which Dr. Zapalac or the  Orthodontist  shall
agree not to  establish,  operate or  provide  orthodontic  or dental  services,
without the prior written  consent of both the New PC and the MSO, at any office
or facility other than the  Orthodontic  Office.  In addition,  such  Employment
Agreement shall provide by its own

                                       10
<PAGE>

terms or by a separate  agreement that if Dr.  Zapalac's or such  Orthodontist's
employment  shall  terminate for any reason  during the Term of this  Agreement,
including  without  limitation  termination  upon the sale of the New PC,  for a
period  of  24  months  after  the   termination   of  Dr.   Zapalac's  or  such
Orthodontist's  Employment  Agreement  with  the New  PC,  Dr.  Zapalac  or such
Orthodontist  shall agree not to establish,  operate or provide  orthodontic  or
dental  services,  without the prior written  consent of both the New PC and the
MSO, at any office practice or facility whatsoever providing services similar to
those  provided by the New PC at any  orthodontic  office within a ten (10) mile
radius.  Such Employment  Agreement (or separate  agreement) shall also provide,
among  other  things,  that in the  event of a breach  of Dr.  Zapalac's  or the
Orthodontist's  agreement  not to compete  with the New PC provided  for in such
Employment  Agreement  (or  separate  agreement),  the MSO shall be  entitled to
receive,  in  addition  to  other  remedies  and  not by way of an  election  of
remedies,  liquidated damages equaling the greater of: (a) Dr. Zapalac's or such
Orthodontist's  income, as shown on the W-2 form prepared by the New PC, for the
most recent  calendar  year; or (b) $300,000.  Such payment shall be made to the
MSO by the New PC immediately  following receipt of the payment from Dr. Zapalac
or the breaching  Orthodontist by the New PC. Each of the MSO and OMEGA shall be
expressly named as a third-party  beneficiary to such agreements between the New
PC and Dr. Zapalac and each  Orthodontist and the rights and remedies of the MSO
and OMEGA  thereunder or otherwise in respect of the  restrictive  covenants set
forth in such agreements shall survive termination of this Agreement.

     3.8  Confidentiality.  (a) The New PC  agrees  and  acknowledges  that  all
materials   provided  by  the  MSO  to  the  New  PC  constitute   "Confidential
Information" and are disclosed in confidence and with the understanding  that it
constitutes  valuable  business  information  developed  by  the  MSO  with  the
assistance of OMEGA at great  expenditures of time, effort and money. The New PC
further agrees that it shall not,  directly or  indirectly,  without the express
prior written consent of the MSO, use or disclose such Confidential  Information
for any  purpose  other than in  connection  with the  services  to be  rendered
hereunder. The New PC further agrees: (i) to keep strictly confidential and hold
in  trust  all  Confidential  Information  and not  disclose  such  Confidential
Information to any third party, including its shareholders, directors, officers,
affiliates,  partners, employees and independent contractors without the express
prior  written  consent  of the  MSO;  and (ii) to  impose  this  obligation  of
confidentiality on its shareholders,  directors, officers, affiliates, partners,
employees  and  independent  contractors.  The  New  PC  acknowledges  that  the
disclosure of Confidential Information to it by the MSO is done in reliance upon
its  representations  and  covenants  in  this  Agreement.  Upon  expiration  or
termination of this Agreement by either party for any reason whatsoever, the New
PC shall  immediately  return  and  shall  cause  its  shareholders,  directors,
officers,  affiliates,  partners,  shareholders  and independent  contractors to
immediately return to the MSO all Confidential Information,  and the New PC will
not,  and  will  cause  its  affiliates,  partners,  employees  and  independent
contractors not to, thereafter use, appropriate,  or reproduce such Confidential
Information.  The New PC further expressly acknowledges and agrees that any such
use,  appropriation or reproduction of any such Confidential  Information by any
of the foregoing  after the  expiration or  termination  of this  Agreement will
result in  irreparable  injury to the MSO and OMEGA,  that the remedy at law for
the  foregoing  would  be  inadequate,  and that in the  event of any such  use,
appropriation,  or reproduction of any such  Confidential  Information after the
termination or expiration of this  Agreement,  the MSO and OMEGA, in addition to
any other  remedies  or damages  available  to either or both of them,  shall be
entitled to  injunctive  or other  equitable  relief  without the  necessity  of
proving  actual damages but such rights to relief shall not preclude the MSO and
OMEGA  from  other  remedies  which may be  available  to either or both of them
hereunder.

                                       11

     (b) The MSO agrees and acknowledges that all materials  provided by the New
PC constitute  "Confidential  Information"  and are disclosed in confidence  and
with the understanding that, except for "Required Disclosure" (as defined below)
it constitutes  valuable business  information  developed by the New PC at great
expenditures  of time,  effort and money.  The MSO further  agrees that it shall
not,  directly or indirectly,  without the express prior written  consent of the
New PC, or as required by Required Disclosure, use or disclose such Confidential
Information  for any purpose  other than in  connection  with the services to be
rendered  hereunder.  The MSO further agrees that except as required by Required
Disclosure  it  shall:  (i) keep  strictly  confidential  and hold in trust  all
Confidential  Information and not disclose such Confidential  Information to any
third  party,  including  its  shareholders,  directors,  officers,  affiliates,
partners,  employees  and  independent  contractors  without the  express  prior
written   consent  of  the  New  PC;  and  (ii)   impose  this   obligation   of
confidentiality on its shareholders,  directors, officers, affiliates, partners,
employees and independent contractors.  The MSO acknowledges that the disclosure
of  Confidential  Information  to it by the New PC is done in reliance  upon its
representations and covenants in this Agreement.  Upon expiration or termination
of this  Agreement  by either  party for any  reason  whatsoever,  the MSO shall
immediately  return  and shall  cause  its  shareholders,  directors,  officers,
affiliates,  partners,  shareholders and independent  contractors to immediately
return to the New PC all  Confidential  Information,  and the MSO will not,  and
will cause its affiliates,  partners,  employees and independent contractors not
to, thereafter use, appropriate, or reproduce such Confidential Information. The
MSO further expressly  acknowledges and agrees that any such use,  appropriation
or  reproduction  of any such  Confidential  Information by any of the foregoing
after the expiration or termination of this Agreement will result in irreparable
injury  to the  New PC and  Dr.  Zapalac  and  that  the  remedy  at law for the
foregoing  would  be  inadequate,  and  that  in  the  event  of any  such  use,
appropriation,  or reproduction of any such  Confidential  Information after the
termination  or expiration of this  Agreement,  the New PC and Dr.  Zapalac,  in
addition to any other  remedies or damages  available to either or both of them,
shall be entitled to injunctive or other equitable  relief without the necessity
of proving  actual  damages but such rights to relief shall not preclude the New
PC and Dr.  Zapalac from other remedies which may be available to either or both
of them  hereunder.  Notwithstanding  anything to the  contrary in this  Section
3.8(b),  the  MSO and  OMEGA  shall  be  permitted  to and  shall  disclose  any
information,  including  Confidential  Information,  provided  by the New PC, as
required  by  Required  Disclosure.   As  used  in  this  Agreement,   "Required
Disclosure" means any disclosures  required be made under Law, including federal
or state  securities  laws, or pursuant to court order,  and any  disclosures to
preserve  the rights of the MSO and OMEGA  under the Stock  Put/Call  Option and
Successor Designation Agreement.

                 PROFESSIONAL SERVICES, CONTROL OF SOLICITATION,
              APPROVAL OF ADVERTISING MATERIAL AND NO RECIPROCATION


     4.1 A  fundamental  understanding  between the  parties  hereto is that the
rendering of  orthodontic  services shall be separate and  independent  from the
provision of  administrative,  management and support services by the MSO. Thus,
the  New PC  shall  have  sole  and  absolute  control  of the  delivery  of all
professional  services  and  treatment  rendered to patients at the  Orthodontic
Offices.

     4.2 No employee or other  representative of the MSO shall be engaged in, or
allowed to

                                       12
<PAGE>

solicit  patients  on behalf of, the New PC, nor shall the MSO have any  control
over the New PC's patients.

     4.3 No  advertising  or promotional  materials,  or other  materials of any
nature,   including   billing  and  collection   forms,   reports,   agreements,
correspondence,  or similar materials,  used in connection with the New PC shall
be used or distributed without having first been approved by the New PC.

     4.4 The parties hereby  acknowledge  and agree that the benefits  conferred
upon each of them hereunder  neither  require nor are in any way contingent upon
the  admission,  recommendation,  referral,  or any  other  arrangement  for the
provision  of any item or service  offered by the MSO to any patients of the New
PC or its shareholders,  officers, directors, employees,  contractors or agents,
nor are such benefits in any way contingent upon the recommendation, referral or
any other  arrangement  for the provision of any item or service  offered by the
New PC or any of its Practice Providers, employees, contractors or agents.

     5.1 In  consideration  of the sums to be paid to the MSO under the terms of
this Agreement, the MSO hereby leases or sub-leases,  as applicable,  to the New
PC during the Term of this Agreement the Orthodontic  Offices, and the leasehold
improvements and fixtures, furniture and equipment at the Orthodontic Offices as
listed from time to time on Schedule 2 attached hereto and  incorporated  herein
by this reference, under the following terms and conditions:

     (a) The MSO is the  lessee  by  assignment  under  lease  for the  premises
occupied by the New PC  (collectively,  the  "Master  Lease") a copy of which is
attached hereto as Exhibit A and incorporated herein by this reference.  The New
PC hereby  acknowledges  that the premises  described under the Master Lease are
suitable for the New PC's  orthodontic  practice.  Based and contingent upon the
New PC's  promise to timely pay all  amounts due under this  Agreement,  the MSO
hereby  agrees to sublease the leased  premises to the New PC upon the following
terms and conditions:

          (i) This sublease between the MSO and the New PC of the premises shall
     be subject to all of the terms and  conditions of the Master Lease.  In the
     event of the  termination  of the MSO's interest as lessee under the Master
     Lease for any reason, then the sublease created hereby shall simultaneously
     terminate, unless the New PC assumes the obligations under the Master Lease
     in question and the Lessor consents thereto.

          (ii) All of the terms and conditions contained in the Master Lease are
     incorporated  herein as terms and  conditions  of the  sublease  (with each
     reference  therein to "Lessor"  and  "Lessee," to be deemed to refer to the
     MSO and the New PC,  respectively)  and,  along with the provisions of this
     Section  5.1(b) and Exhibit "A," shall be the complete terms and conditions
     of the sublease created hereby.

          (iii)  Notwithstanding  the foregoing,  as between the MSO and the New
     PC,  the MSO shall  remain  responsible  for  meeting  the  obligations  of
     "Lessee" under the sections  entitled  Rent,  Additional  Rent  Adjustment,
     Insurance  on  Fixtures,  Liability  Insurance,  Repairs,  and Taxes of the
     Master Lease,  all of which  obligations  shall be considered  MSO Expenses
     hereunder and the New PC shall have no monetary  obligation in that regard.
     In  addition,  as between the MSO and the New PC, the MSO shall  retain the
     right to exercise any options to purchase the  premises,  or other  similar
     rights of ownership or  possession,  which may be granted  under the Master
     Lease, and the New PC shall have no rights in that regard.

          (iv) In the event this Agreement is terminated according to its terms,
     this sublease shall also terminate automatically.

          (v) If the Master Lease contains an option to renew the terms thereof,
     the MSO shall  notify the New PC, at least 30 days prior to the  expiration
     of the time for exercising such option,  of

                                       14
<PAGE>

     the  MSO's  intention  to  renew  or not to  renew  such  term.  If the MSO
     determines not to renew such term, the MSO shall provide or arrange for the
     provision of comparable office space (the "Substitute  Orthodontic Office")
     within a radius of fifteen  (15)  miles of the  Orthodontic  Office,  which
     Substitute  Orthodontic  Office shall be subject to the approval of the New
     PC (which  approval  shall not be  unreasonably  withheld or delayed).  The
     lease or sublease for such Substitute  Orthodontic  Office,  as applicable,
     shall be  substituted  for the lease  described on Exhibit A hereto and all
     references  to the "Master  Lease" shall  thereafter  be  applicable to the
     lease or sublease  for the  Substitute  Orthodontic  Office for purposes of
     this Agreement, ab initio.

          (vi)  The  Alternative  Dispute  Resolution  provisions  set  forth in
     Article 14 of this Agreement  shall not apply to any issues  concerning the
     Sub-Lease,  the New PC's  tenancy  or the  MSO's  rights  and  remedies  as
     Sub-Lessor.

     5.2 The  MSO  shall  provide  the New PC at the  Orthodontic  Offices  such
additional  leasehold  improvements,   fixtures,   furniture,   furnishings  and
equipment as may be mutually  agreed to with the New PC and reflected  from time
to time on a  supplement  to  Schedule  2  hereto.  The use by the New PC of all
leasehold improvements,  fixtures, furniture, furnishings and equipment provided
hereunder shall be subject to the following conditions:

     (a)  Title  to all  such  leasehold  improvements,  fixtures,  furnishings,
furniture and  equipment  shall remain in the MSO and upon  termination  of this
Agreement,  the New PC shall immediately return and surrender all such leasehold
improvements,  fixtures,  furniture,  furnishings and equipment to the MSO in as
good condition as when received, normal wear and tear excepted.

     (b) The MSO shall be fully and  entirely  responsible  for all  repairs and
maintenance of all such leasehold improvements, fixtures, furniture, furnishings
and equipment;  provided,  however,  that the New PC agrees that it will use its
best  efforts to prevent  damage,  excessive  wear,  and  breakdown  of all such
leasehold  improvements,  fixtures,  furniture,  furnishings and equipment,  and
shall advise the MSO of any and all needed repairs and equipment failures.

     (c)  The  obligation  of the MSO to  provide  the  leasehold  improvements,
fixtures, furniture, furnishings and equipment stated herein shall be concurrent
and co-extensive with the Term of this Agreement.

     5.3. No Warranty.

     (a)  THE  NEW  PC  ACKNOWLEDGES   THAT  THE  MSO  MAKES  NO  WARRANTIES  OR
REPRESENTATIONS,  EXPRESS OR IMPLIED,  AS TO THE  SUITABILITY OR ADEQUACY OF ANY
LEASEHOLD IMPROVEMENTS,  FIXTURES, FURNITURE, FURNISHINGS,  EQUIPMENT, INVENTORY
OR SUPPLIES  PROVIDED OR LEASED OR SUBLEASED  PURSUANT TO THIS AGREEMENT FOR THE
CONDUCT OF AN ORTHODONTICS PRACTICE OR FOR ANY OTHER PARTICULAR PURPOSE.

                                       15
<PAGE>

     (b) Nothing in this Agreement  shall be construed to affect or limit in any
way the  professional  discretion  of the  Practice  Providers to select and use
fixtures, furniture, furnishings and equipment, inventory and supplies purchased
or provided  by the MSO in  accordance  with the  provisions  of this  Agreement
insofar as such selection or use constitutes or might constitute the practice of
dentistry or orthodontics.

                                  COMPENSATION


     As  consideration  for the performance of all of its duties and obligations
as  provided  in this  Agreement,  including  but not  limited to, the costs and
expenses  associated  with  furnishing  the  services,  personnel,   facilities,
leasehold improvements, fixtures, furniture, furnishings, equipment, inventories
and supplies provided for herein, the MSO shall receive compensation in the form
of monthly  management fees (the  "Management  Fees") based upon a predetermined
percentage of the "Practice  Revenues",  as defined and determined in accordance
with the  provisions  set forth in Schedule 3 attached  hereto and  incorporated
herein by this reference,  as such Schedule may be amended by the New PC and the
MSO from time to time. It is acknowledged by and between the parties hereto that
the MSO and/or its  affiliates  has (have)  incurred  substantial  expenses  and
future  obligations  in  acquiring  the capital  stock of the MSO,  acquiring or
otherwise  establishing  the  Orthodontic  Offices,  establishing  its  systems,
including fees for consultants and other professionals,  interest expense, lease
obligations,  and costs of furnishing or refurbishing  the premises at which the
Orthodontic   Offices  are  located.   The  MSO  has  also  assumed  substantial
obligations associated with the continuing operation of the Orthodontic Offices,
including  those of  lessee,  obligor  and  guarantor  and  obligor  on loans to
establish and operate the Orthodontic  Offices. The parties,  therefore,  having
considered various  compensation  formulae,  acknowledge and agree that in order
for the MSO to  receive  a fair  and  reasonable  return  for its  expenses  and
obligations,  and a fair return for the lease of the premises and  equipment and
for providing the services contemplated hereunder,  that the agreed compensation
is not excessive. In consideration of the foregoing,  the parties agree that the
monthly  Management Fees payable to the MSO by the New PC for services  rendered
pursuant to this  Agreement  shall be reviewed and subject to  adjustment at the
close of each year of the Term of this Agreement  based upon industry  standards
of practice  and the MSO's costs in  performing  the required  services.  If the
parties cannot agree within thirty (30) days prior to the close of any such year
on the terms of any  adjustment to the Management  Fees for the following  year,
then the then  existing  Management  Fees  shall  remain in  effect.  The New PC
specifically agrees that the MSO may defer actual receipt of its Management Fees
and/or  advance  monies for purposes of managing the New PC's cash flow, and the
MSO may repay itself such advances or pay said deferred  Management Fees when it
deems appropriate.

                                SECURITY INTEREST


     As  assurance  and  collateral  security  for the  payment  of the  monthly
Management  Fees  owed  to the MSO  pursuant  to this  Agreement  and any  funds
advanced by the MSO to or on behalf of the New PC pursuant to this Agreement and
for the faithful and timely  performance  of all the covenants and conditions to
be  performed

assigns and  transfers to the MSO a security  interest,  pursuant to the Uniform
Commercial Code of the State, in and to five hundred thousand dollars ($500,000)
of Practice Revenue and accounts  receivable of patients of the New PC, together
with all proceeds thereof (collectively,  the "Collateral"),  and further agrees
not to pledge, assign,  transfer or convey any of the Collateral or any proceeds
therefrom, without the prior written consent of the MSO, except to affiliates of
the MSO.  Concurrent  with the  execution  of this  Agreement,  the New PC shall
execute a  Security  Agreement,  similar in form and  content  as that  attached
hereto as Exhibit D and incorporated  herein by this reference in order that the
MSO may perfect its interest in the Collateral.  The New PC expressly  agrees to
execute any appropriate UCC-1 Financing  Statement and UCC-1 Fixture filings, if
so requested in writing by the MSO.

                                    ARTICLE 8
                                    COVENANTS


     8.1 New PC's Covenants.  As further consideration for the MSO's performance

by the MSO,  within a radius of ten (10) miles of the  Orthodontic  Office or of
such other  orthodontic  practice,  without  the MSO's  prior  written  consent.
Teaching  and/or  consulting  by Dr.  Zapalac shall not be considered to violate
this Section 8.1(c).

     (d) The New PC recognizes the  proprietary  interest of OMEGA in and to its
OMEGA  Patient  Scheduling  System and the MSO in its systems for  managing  the
delivery of orthodontic care and all policies,  procedures,  operating  manuals,
forms,  contracts and other information  (collectively,  the "MSO  Information")
regarding such system.  The New PC acknowledges  and agrees that all information
relating  to the  OMEGA  Patient  Scheduling  System  and  the  MSO  Information
constitutes  trade secrets of OMEGA and/or the MSO. The New PC hereby waives any
and all right,  title and  interest  in and to such trade  secrets and agrees to
return all copies of such trade secrets and information relating thereto, at its
expense, upon termination of this Agreement.

     (e) The New PC acknowledges  and agrees that OMEGA and the MSO are entitled
to

                                       17
<PAGE>

prevent  their  respective   competitors  from  obtaining  and  utilizing  their
respective trade secrets.  The New PC agrees to hold OMEGA'S and the MSO's trade
secrets in  strictest  confidence  and not to disclose  them or allow them to be
disclosed  directly or indirectly to any person or entity other than persons who
are engaged by the New PC to perform  duties in  connection  with the New PC and
who have a need to know such trade  secrets in the  performance  of their duties
for the New PC, without OMEGA's or the MSO's prior written consent,  as the case
may be. The New PC acknowledges  its fiduciary  obligations to OMEGA and the MSO
and the  confidentiality  of its relationships with OMEGA and the MSO and of any
information  relating to the services and business  methods of OMEGA and the MSO
which it may  obtain  during the term of this  Agreement.  The New PC shall not,
either during the term of this  Agreement or at any time after the expiration or
sooner  termination  hereof,   disclose  to  anyone,  other  than  employees  or
independent  contractors  of OMEGA  and the MSO who use  OMEGA's  and the  MSO's
system in the course of the  performance of their duties,  any  confidential  or
proprietary information or trade secrets obtained by the New PC. The New PC also
agrees to place  any  persons  to whom said  information  is  disclosed  for the
purpose of  performance  under legal  obligation  to treat such  information  as
strictly confidential.

     8.2 MSO's Covenants.  As further consideration for the New PC's performance
of the terms and conditions of this Agreement, the MSO covenants, represents and
warrants  (which  covenants,  representations  and warranties  shall survive the
execution of this  Agreement)  that during the Term of this  Agreement,  the MSO
agrees not to  establish,  develop or open any  offices in  affiliation  with an
orthodontist  for the provision of orthodontic  services  within a ten (10) mile
radius of the  Orthodontic  Offices,  without the express written consent of the
New PC.

                             INSURANCE AND INDEMNITY

     9.1 Insurance to be Maintained by the New PC.  Throughout  the Term of this
Agreement,  the New PC shall  maintain  in full force and  effect  comprehensive
professional  liability  insurance  with  limits of not less than  $500,000  per
occurrence  and  $1,000,000  annual  aggregate  per Dr.  Zapalac and each of the
Orthodontists providing services for the New PC and a separate limit for the New
PC. The New PC shall be responsible for all liabilities  within  deductibles and
for all liabilities in excess of the limits of such policies.  The MSO agrees to
negotiate for and cause premiums to be paid on behalf of the New PC with respect
to such insurance.  Premiums and deductibles with respect to such policies shall
not be MSO  Expenses.  The  New PC also  agrees  to name  the MSO and  OMEGA  as
co-insureds.  The New PC agrees to deliver to the MSO and OMEGA a certificate of
insurance indicating such coverage.

     9.2  Insurance to be  Maintained  by the MSO.  Throughout  the Term of this
Agreement, the MSO will use reasonable efforts to provide and maintain, as a MSO
Expense, (a) comprehensive professional liability insurance for all professional
employees of the MSO with limits as  determined  reasonable  by the MSO; and (b)
comprehensive  general liability and property insurance covering the Orthodontic
Office premises and operations.

     9.3 Tail  Insurance  Coverage.  The New PC will cause Dr.  Zapalac and each
Orthodontist (if any) providing services to enter into an agreement with the New
PC that upon  termination of Dr. Zapalac's or such  Orthodontist's  relationship
with the New PC, for any reason,  tail  insurance  coverage will be purchased by


                                       18
<PAGE>

Dr.  Zapalac  or such  Orthodontist.  Such  provisions  may be  contained  in an
employment agreement,  restrictive covenant agreement or other agreement entered
into by the New PC and Dr.  Zapalac or the  Orthodontist,  and the New PC hereby
covenants with the MSO to enforce such provisions relating to the tail insurance
coverage or to provide such coverage at the expense of the New PC or Dr. Zapalac
or each such Orthodontist.

     9.4  Additional  Insureds.  The  New PC and  the  MSO  agree  to use  their
reasonable  efforts to have each  other  named as an  additional  insured on the
other's respective liability insurance policies.

     9.5 Indemnification.  The New PC shall indemnify,  hold harmless and defend
the MSO and  OMEGA  and  their  respective  officers,  directors,  shareholders,
employees and representatives,  from and against any and all liability,  losses,
damages, claims, causes of action, expenses judgments, settlements, lawsuits and
obligations  (including  reasonable  attorneys' fees), whether or not covered by
insurance, caused or asserted to have been caused, directly or indirectly, by or
as a result of the performance of orthodontic services or the performance of any
intentional  acts,  negligent  acts  or  omissions  by  the  New PC  and/or  its
affiliates,  its  shareholders,   agents,  the  Practice  Providers,  its  other
employees and/or its subcontractors (other than the MSO) during the Term hereof.
The MSO shall  indemnify,  hold  harmless  and defend the New PC, its  officers,
directors,  shareholders and employees,  from and against any and all liability,

attorneys'  fees),  caused  or  asserted  to  have  been  caused,   directly  or
indirectly,  by or as a  result  of the  performance  of any  intentional  acts,
negligent  acts  or  omissions  by the  MSO  and/or  its  shareholders,  agents,
employees and/or subcontractors (other than the New PC) during the Term hereof.

                                   ARTICLE 11
                     AUTHORIZED AGENT AND POWERS OF ATTORNEY

     Unless and until there is an effective  termination of this Agreement,  the
New PC hereby  designates the MSO (and its  designees) its authorized  agent and
lawful  attorney-in-fact  for purposes of depositing  payments,  paying accounts
payables,  signing  checks,  negotiating  and signing  contracts for services or
goods,  securing  loans  or  incurring  obligations  on  behalf  of the  New PC;
provided,  however, that all contracts or fees set for services on behalf of the
New PC will be subject to final  approval and  acceptance  by the New PC. Unless
and until there is an effective termination of this Agreement, the New PC hereby
appoints  the  MSO  (and  its  designees)   its  authorized   agent  and  lawful
attorney-in-fact  to collect all bills and accounts  receivable for professional
fees,  charges and other amounts and authorizes the MSO through its designees to
take possession of all checks,  money orders and similar instruments received as
payment of receivables to be deposited into the New PC Account. Unless and until
there is an effective termination of this Agreement,  the New PC hereby appoints
the MSO as the New PC's  attorney-in-fact,  with full power and authority in the
place and stead of the New PC, in the MSO's  discretion,  to endorse in the name
of the New PC any checks, payments,  notes, insurance payments and money orders,
to withdraw funds for payments of expenses,  including Management Fees and other
sums  payable to the MSO,  to open and close the New PC  Account  and other bank
accounts,  to take any action and to execute any other  instrument which the MSO
may deem necessary or advisable to accomplish the purposes hereof. The powers of
attorney granted herein are coupled with an interest and are revocable only upon
an  effective  termination  of this  Agreement.  Third  parties and entities and
persons not a party to this  Agreement  are  entitled  to rely on the  foregoing
attorneys-in-fact  and an affidavit of the MSO attesting thereto. The acceptance
of this  appointment  by the MSO shall not  obligate  it to perform  any duty or
covenant  required  to be  performed  by the New PC under or by  virtue  of this
Agreement. Notwithstanding the foregoing powers of attorney, the New PC shall at
any  time,  on the  request  of the MSO,  sign  financing  statements,  security
agreements or other agreements  necessary or advisable to accomplish the purpose
of this Agreement.  Upon the New PC's failure to sign said financing statements,
security  agreements or other agreements,  the MSO is authorized as the agent of
the New PC to sign any such instruments.  The New PC may review all deposits and
expenses upon request.

                                   ARTICLE 12
                       INDEPENDENT CONTRACTOR RELATIONSHIP


     Neither  the New PC nor its  employees  shall  have any  claim  under  this
Agreement or otherwise against the MSO for worker's  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 the New PC. Since  neither the New PC nor its  employees  are
employees  of the MSO,  the MSO  shall  not  withhold  on  behalf  of the New PC
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 the New PC.

                                   ARTICLE 13
                                  MISCELLANEOUS

                                       21
<PAGE>

     13.1 Access to Records.  From and after any  termination,  each party shall
provide the other party with  reasonable  access to books and records then owned
by it to permit  such  requesting  party to satisfy  reporting  and  contractual
obligations which may be required of it.

     13.2 Patient Records. Upon termination of this Agreement,  the New PC shall
retain all patient  dental  records  maintained  by the New PC or the MSO in the
name of the New PC. During the term of this Agreement,  and thereafter,  the New
PC or its designee shall have reasonable  access during normal business hours to
the New PC's and the MSO's  records,  including,  but not limited to, records of
collections,  expenses and  disbursements  as kept by the MSO in performing  the
MSO's obligations under this Agreement,  and the New PC may copy any or all such
records.

     13.3 The New PC's Control Over the  Orthodontic  Practice.  Notwithstanding
the authority  granted to the MSO herein,  the MSO and the New PC agree that the
New PC,  personally or through Dr. Zapalac or any of its  Orthodontists (if any)
and other Practice  Providers,  shall have complete control and supervision over
the professional  aspects of the New PC's practice,  as well as the provision of
all professional  services,  including,  without limitation,  the selection of a
course of treatment for a patient,  the  procedures or materials to be used as a
part of such  course  of  treatment,  and the  manner  in which  such  course of
treatment is carried out by the New PC. The New PC shall have sole  authority to
direct the business,  professional,  and ethical  aspects of the New PC. The MSO
shall have no  authority,  directly or  indirectly,  to  perform,  and shall not
perform, any orthodontic  function,  or to influence or otherwise interfere with
the exercise of the New PC's professional judgment. The MSO may, however, advise
the  New  PC as to the  relationship  between  its  performance  of  orthodontic
functions and the overall administrative and business functioning of the New PC.

                         ALTERNATIVE DISPUTE RESOLUTION

     14.1 Alternative Dispute Resolution.

     (a) If a dispute  arises  under this  Agreement  which  cannot be  resolved
informally  by the  parties,  any party may invoke the  procedures  set forth in
Exhibit E hereto and the parties agree to use these procedures, except paragraph
(b) of this Section 14.1, prior to any party pursuing other available  remedies.
The parties  will meet and attempt in good faith to resolve any  controversy  or
claim arising out of or relating to this Agreement.

     (b) Notwithstanding anything in this Section 14.1 to the contrary:

          (i) Nothing in this Section 14.1 shall preclude any party from seeking
     a preliminary  injunction or other provisional  relief,  either prior to or
     during the proceeding provided for in this section, if in its judgment such
     action is necessary to avoid  irreparable  damage or to preserve the status
     quo.

          (ii)  The  parties  shall  accept  as  correct,   final,  binding  and
     conclusive the  determination  by the outside  accountants then employed by
     the MSO as to the  calculation of any and all  Management  Fees

                                       22
<PAGE>

     owed by the New PC to the MSO hereunder,  and such determination  shall not
     be subject to the  provisions  of this  Section  14.1.  Disputes  as to the
     proper  interpretation  of the provisions of this Agreement  which describe
     how those amounts are to be  calculated,  however,  shall be subject to the
     provisions of this Section 14.1.

          (iii) Any determination by either party not to renew this Agreement in
     accordance  with the terms and  provisions of this  Agreement  shall not be
     subject to the provisions for dispute resolution in this Section 14.1.


                                   ARTICLE 15
                               GENERAL PROVISIONS

     15.1 Notices.  Any notice to be given pursuant to this  Agreement  shall be
deemed  effective if given  personally,  or by  telephone,  telegram,  telecopy,
facsimile  or other  electronic  transmission,  or by  letter to an  officer  or
administrator  of OMEGA,  the MSO or the New PC,  as the case may be.  Notice in
person,  or by telephone,  telegram or electronic  transmission  shall be deemed
effective when given. Notice by mail shall be deemed effective  seventy-two (72)
hours after  deposit in the United  States mails,  and properly  addressed  with
postage prepaid.

     Notices to the New PC shall be given as follows:

     Austin, Texas 78759
     Attn: Jeff S. Zapalac, D.D.S.


or such other  address as may be furnished by the New PC to the MSO from time to
time in writing.

     Attn: Robert Schulhof


or other such  addresses  as may be furnished by the MSO to the New PC from time
to time in writing.

     15.2  Confidentiality.  No party hereto shall disseminate or release to any
third party any information  regarding any provision of this  Agreement,  or any
financial information regarding the other parties (past, present or future) that
was obtained in the course of the negotiation of this Agreement or in the course
of the performance of this Agreement,  without the other party's or parties' (as
the case may be) written approval;

                                       23
<PAGE>

provided,  however,  the  foregoing  shall  not  apply to  information  which is
required to be disclosed by Law,  including federal or state securities laws, or
pursuant to court order.

     15.3 Contract  Modifications for Prospective Legal Events. In the event any
state or  federal  Laws,  now  existing  or  enacted  or  promulgated  after the
effective  date of this  Agreement,  are  interpreted  by judicial  decision,  a
regulatory  agency  or legal  counsel  for both  parties  in such a manner as to
indicate that the structure of this  Agreement may be in violation of such Laws,
the New PC and the MSO shall amend this  Agreement as necessary.  To the maximum
extent possible,  any such amendment shall preserve the underlying  economic and
financial arrangements between the New PC and the MSO.

     15.4  Remedies  Cumulative.  No  remedy  set  forth  in this  Agreement  or
otherwise conferred upon or reserved to any party shall be considered  exclusive
of any other  remedy  available  to any party,  but the same shall be  distinct,
separate  and  cumulative  and may be  exercised  from  time to time as often as
occasion may arise or as may be deemed expedient.

     15.5 No Obligation to Third Parties.  None of the obligations and duties of
the MSO or the New PC under this Agreement  shall in any way or in any manner be
deemed to create  any  obligation  of the MSO or of the New PC to, or any rights
in, any person or entity not a party to this  Agreement  other than OMEGA  which
shall be deemed a party for limited purposes as set forth in this Agreement.

     15.6 Entire Agreement.  This Agreement including the Schedules and Exhibits
hereto,  together  with the Stock  Put/Call  Option  and  Successor  Designation
Agreement of even date herewith and the Employment  Agreement(s)  (including the
related  non-competition  agreements  or  covenants),   constitutes  the  entire
agreement between the parties concerning this subject matter, and supersedes all
prior and contemporaneous agreements,  representations and understandings of the
parties  concerning  the  contents  hereof.  No  supplement,   modification,  or
amendment to this Agreement  shall be binding unless  executed in writing by all
of the parties hereto,  except as otherwise provided herein. No waiver of any of
the provisions of this  Agreement  shall be deemed to constitute a waiver of any
other provision, whether similar or not similar, nor shall any waiver constitute
a continuing  waiver.  No waiver shall be binding unless  executed in writing by
the party making the waiver.

     15.7  Assignment.  The  rights  and the  duties of the  parties  under this
Agreement may not be assigned or transferred  without the prior written  consent
of the non-assigning  party,  which consent shall not be unreasonably  withheld;
provided,  however,  that the MSO shall be  permitted  to assign  its rights and
obligations  hereunder without the consent of the New PC to any person,  firm or
corporation  controlled by the MSO,  controlling the MSO or under common control
with the MSO.

     15.8  Attorneys'  Fees.  If  any  arbitration  or  other  legal  action  or
proceeding is brought to enforce this  Agreement,  because of any alleged breach
hereof,  or for a  declaration  of any rights  and  obligations  hereunder,  the
prevailing party in such arbitration,  action or proceeding shall be entitled to
recover its costs incurred  therein,  including  reasonable  attorneys' fees, in
addition to any other relief to which it may be entitled,  all as determined and
awarded by the arbitrator or court as part of its judgment or decision  therein,
as the  case  may be.  If the  parties  agree to take  any  dispute  under  this
Agreement to mediation, the costs of the mediator and the

                                       24
<PAGE>

mediation shall be borne equally by the parties hereto.

     15.9 Governing  Law. This  Agreement  shall be governed by and construed in
accordance with the laws of the State.  The parties  acknowledge that the MSO is
not  authorized or qualified to engage in any activity which may be construed or
deemed to constitute  the practice of dentistry or  orthodontics.  To the extent
any act or service  required of the MSO in this Agreement should be construed or
deemed,  by any  governmental  authority,  agency  or  court to  constitute  the
practice of dentistry or orthodontics, the performance of said act or service by
the MSO shall be deemed waived and forever  unenforceable  and the provisions of
Section 15.14 shall be applicable.

     15.10 Events  Excusing  Performance.  Neither  party shall be liable to the
other party for failure to perform any of the  services  required  herein in the
event of strikes, lock-outs, calamities, acts of God, unavailability of supplies
or other  events over which that party has no control for so long as such events
continue, and for a reasonable period of time thereafter.

     15.11  Compliance with Applicable  Laws. Both parties shall comply with all
applicable  Laws and  restrictions  imposed  thereunder  in the conduct of their
obligations under this Agreement.

     15.12 Language  Construction.  The parties  acknowledge that each party and
its counsel have reviewed and revised this Agreement and that the normal rule of
construction to the effect that any  ambiguities are to be resolved  against the
drafting party shall not be employed in the interpretation of this Agreement.

     15.13 Amendments. This Agreement may be amended only by the written consent
of both parties.

     15.14 Severability. In the event any provision of this Agreement is held by
a court of  competent  jurisdiction  to be  illegal  or  unenforceable,  (i) the
parties  shall  amend  this  Agreement  in  order to carry  out the  intent  and
essential  business  purposes of this Agreement as closely  possible  within the
requirements of applicable  provisions of Law as determined by such a court, and
(ii) the remaining provisions of this Agreement shall continue in full force and
effect.

     15.15 No Waiver. The waiver by either party to this Agreement of any one or
more defaults, if any, on the part of the other party, shall not be construed to
operate as a waiver of the other or future defaults under this Agreement.

     15.16  Captions.  Captions to paragraphs in this  Agreement are for ease of
reference, and shall not be considered an interpretation of the paragraph.

     15.17 Counterparts. This Agreement may be executed simultaneously in one or
more counterparts, each of which shall be deemed an original.

                                   SCHEDULE 3

                         COMPENSATION - MANAGEMENT FEES


     The MSO shall receive,  as  compensation  for the performance of all of its
obligations and duties contained in the Agreement, monthly Management Fees in an
amount equal to Seventy-Five Percent (75%) of the Practice Revenues, and the New
PC shall be entitled to  Twenty-Five  Percent (25%) of such  Practice  Revenues,
except as the parties may otherwise  agree from time to time in writing.  At the
end of each twelve (12) month period  during the Term the MSO shall  provide the
New PC with an unaudited  internal  accounting of the MSO Expenses,  prepared in
accordance  with the  accrual  method  of  accounting.  If the MSO  Expenses  as
reflected in such  accounting as having been paid by the MSO are less than sixty
(60%) percent of the Practice Revenues for such twelve month period, fifty (50%)
percent  of such  difference  shall  be  returned  by the MSO to the New PC as a
profit incentive rebate (the "Rebate").  If the Agreement to which this Schedule
3 is attached is terminated or expires,  the foregoing  Management Fees shall be
payable to the MSO based on all  Practice  Revenue  collected  as of the date of
termination or expiration.

     Payment  to the MSO  shall  be made in  monthly  installments  based on the
Practice Revenues realized by the MSO for services rendered  hereunder.  The MSO
shall  distribute the proceeds from the New PC Account and allocate the proceeds
between the MSO and the New PC as described  above, on or before the 15th day of
the succeeding  month.  In the event the 15th day falls on a weekend or holiday,
then said  distribution  shall be made on the next  business  day.  The  parties
hereto may agree to handle such matters in a different manner.

     For  purposes  of this  Agreement,  "Practice  Revenues"  shall  mean gross
collections  of all  revenues  generated  by or on behalf of the New PC (whether
through subsidiaries or affiliates), including, but not limited to, all fees and
charges collected as a result of professional  orthodontic services furnished to
patients by the New PC and for any other  goods or services  sold or provided to
such patients.

                               SECURITY AGREEMENT


     THIS  SECURITY  AGREEMENT  is  effective  as of the ______ day of _________
1997, by _____________________, PC, a Texas corporation (the "New PC"), and Jeff
S. Zapalac, D.D.S. ("Dr. Zapalac") who is duly licensed to practice orthodontics
in the State and Omega Orthodontics of Austin, Inc., a Delaware corporation (the
"MSO") with reference to the following facts:

     WHEREAS,  pursuant to a Management  Services  Agreement (the  "Agreement"),
dated as of the date hereof,  between the New PC and the MSO, as  assurance  and
collateral  security for the payment of the monthly  Management Fees owed to the
MSO pursuant to the Agreement and any funds  advanced by the MSO to or on behalf
of the  New PC  pursuant  to the  Agreement  and  for the  faithful  and  timely
performance  of all the covenants  and  conditions to be performed by the New PC
under  the  Agreement  (collectively,  the  "Obligations")  the New PC agreed to
pledge,  grant,  bargain,  assign and  transfer to the MSO a security  interest,
pursuant to the Uniform  Commercial  Code of the State,  in and to Five  Hundred
Thousand  ($500,000) dollars in Practice Revenue and the accounts  receivable of
patients of the New PC, together with all proceeds  thereof  (collectively,  the
"Collateral");

     WHEREAS,  the New PC is obligated  as a condition to the MSO's  performance
under the Agreement to execute and deliver this Security Agreement;

     NOW, THEREFORE,  in consideration of the foregoing and of the covenants and
agreements hereinafter set forth, the parties hereto agree as follows:

     1. Grant of Security Interest.  As and for collateral  security for payment
by the New PC of the  Obligations  and any and all  amounts  payable  under this
Security Agreement (collectively,  the "Secured Obligations"), the New PC hereby
pledges, grants,  bargains,  assigns and transfers to the MSO, and grants to the
MSO a security  interest in, the Collateral.  Dr. Zapalac shall cause the New PC
to perform  fully and on a timely  basis all of the New PC's  obligations  under
this Security  Agreement.  The MSO may at its option file a financing  statement
(Form UCC-1) in order to perfect its security interest hereunder.

     2.  Representations and Warranties.  The New PC represents and warrants all
of the accounts  receivable  constituting a portion of the Collateral of the New
PC pledged to the MSO are and will be validly created obligations of each of the
obligors who incurred same for services actually rendered in the ordinary course
of business of the New PC. Further,  the New PC represents and warrants that the
Collateral is not subject to any lien, pledge,  charge,  encumbrance or security
interest or right or option on the part of any third person.

     3. Release of Security Interest.  Upon the termination of the Agreement and
payment in full of the accrued  Management Fees thereunder and any and all other
Secured Obligations,  the MSO shall release its security interest hereunder, and
will deliver to the New PC any property forming part of the Collateral delivered
to the MSO and then held by the MSO hereunder.

     4.  Realization  of  Collateral.  The MSO shall have,  with  respect to the
Collateral,  the rights and

                                       34
<PAGE>

obligations of a secured party under the Uniform  Commercial  Code as adopted in
the state of Texas (the "State"). Such rights shall include, without limitation,
the following:

     A. The right,  upon default,  to have the Collateral,  or any part thereof,
transferred to its own name or to the name of its nominee;

     B. The  right,  upon  default,  to sell,  assign or  deliver as much of the
Collateral  as is  reasonably  necessary  to repay  the  defaulted  indebtedness
(together with expenses  attendant upon such sale and  repayment),  at public or
private  sale,  as the MSO may  elect,  either  for cash or on  credit,  without
assumption  of any  credit  risk and  without  demand or  advertisement  (unless
otherwise required by law).

     C.  The New PC  hereby  irrevocably  authorizes  the MSO to sign  and  file
financing  statements naming the New PC as the debtor and the MSO as the secured
party, at any time with respect to any Collateral,  without the signature of the
New  PC.  The  New PC  hereby  irrevocably  appoints  the  MSO as the  New  PC's
attorney-in-fact,  with full  authority in the place and stead of the New PC and
in the name of the New PC,  from time to time in the MSO's  discretion,  to take
any action and to execute any  instrument  which the MSO may deem  necessary  or
advisable to accomplish the purposes hereof. The attorney-in-fact granted herein
is coupled with an interest and is  irrevocable.  Third parties and entities and
persons  not a party to this  Security  Agreement  are  entitled to rely on this
attorney-in-fact  and an affidavit of the MSO attesting thereto.  The acceptance
of this  appointment  by the MSO shall not  obligate  it to perform  any duty or
covenant  required  to be  performed  by the New PC  under or by  virtue  of the
Collateral. Notwithstanding the foregoing power of attorney, the New PC shall at
any  time  on the  request  of the  MSO,  sign  Financing  Statements,  security
agreements or other agreements with respect to any Collateral. Upon the New PC's
failure  to  sign  said  Financing  Statements,  security  agreements  or  other
agreements,  the MSO is  authorized  as the agent of the New PC to sign any such
instruments.  Upon the  request of the MSO,  the New PC agrees to pay all filing
fees and to  reimburse  the MSO on demand for all costs and expenses of any kind
(including,  without  limitation,  legal fees) incurred in any way in connection
with the Collateral.

     5.  Purchase  of  Collateral.  At any such  private  or public  sale of the
Collateral  or  part  thereof,  the  MSO may  purchase  and pay for the  same by
cancellation of such portion of the Obligations, equal to the purchase price and
free of any  right  of  redemption  on the part of the New PC.  the MSO  agrees,
however,  that the New PC shall  have all  rights,  including  rights of notice,
provided by the  Uniform  Commercial  Code as adopted in the State.  In any case
where notice is required,  five days' notice shall be deemed reasonable  notice.
In the event of any sale  hereunder,  the MSO shall  apply the  proceeds  in the
order set forth  below in  Paragraph  6 hereof.  the MSO may have  resort to the
Collateral or any portion thereof with no requirements on the part of the MSO to
proceed first against any other person or property.

     6.  Application of Collateral.  Proceeds from the sale of the Collateral or
any part thereof shall be applied by the MSO in the following order:

     A. To the payment of the costs and expenses of  collection  incurred by the
MSO,  including,  without  limitation,  attorneys' fees and all other reasonable
expenses, liabilities and costs incurred by the MSO in connection therewith;

                                       35
<PAGE>

     B. To the payment of the whole  amount  then owing and unpaid for  advances
and/or Management Fees;

     C. To the payment in full of all other  Obligations of the New PC under the
Agreement; and

     D. To the payment to the New PC of any  surplus  then  remaining  from such
proceeds.

     7.  Extension of Agreement.  No renewal or extension of the  Agreement,  no
release  or  surrender  of  any  Collateral  given  as  security  in  connection
therewith,  and no delay in  enforcement  thereof or in exercising  any right or
power with respect  thereto or hereunder shall affect the rights of the MSO with
respect to the Collateral or any part thereof.

     8.  Notices.  Any notice to be given  pursuant to this  Agreement  shall be
deemed  effective  the same day when  such  notice  is given  personally,  or by
telegram,  or  electronic  transmission  to the  President  of the party to whom
notice is being given. Notice by mail shall be deemed effective three days after
deposit in the United States mail, and properly addressed with postage prepaid.

                                    EXHIBIT E


                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A. Method of Invoking ADR Procedures


     A. Method of Invoking ADR Procedures

     1.  These  procedures  may be invoked  by any party to an  agreement  which
incorporates  these  procedures  by  giving  written  notice to the other of the
dispute  and   designating  a  person  with   decision-making   authority   (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required  to respond to the  disputing  party's  notice
within five (5) business days by designating in writing its own  representative.
A party may choose  more than one person to  represent  it. If a party  appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties,  each acting  through its  representative,  shall meet at a
mutually  acceptable  time  and  place  within  five  business  days  after  the
non-disputing party designates its representative to the other. At that meeting,
the  parties  shall  attempt  in good faith to  negotiate  a  resolution  of the
dispute,  or  failing  that,  to agree on a method  for  resolving  the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer  period of time as the parties may mutually  agree,  the parties have not
succeeded in  negotiating  a resolution of the claim or dispute or agreeing on a
dispute  resolution  mechanism,  they shall  submit the dispute to  mediation in
accordance with the procedures set forth herein.

     4. The  parties  will  jointly  appoint a mutually  acceptable  mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above,  then the parties  shall select a neutral third party from
either the Center for Public  Resources,  New York,  New York ("CPR")  Panels of
Neutrals,  the American  Arbitration  Association  ("AAA") or the Association of
Attorney Neutrals ("AAN"), with the assistance of such organization,  unless the
parties agree otherwise in finding a mutually acceptable mediator.

     5. Acquisition shall bear 50% and the New PC and Dr. Zapalac shall bear

                                       39
<PAGE>

50% of the fees and costs of the  mediator and any fees and costs of CPR, AAA or
AAN.

     6. The parties  agree to  participate  in good faith in the  mediation  and
negotiations  related thereto for a period of thirty (30) days from  appointment
of a mediator by any of the parties or the CPR, AAA or AAN.


B. Mediation procedures

     1. The mediator shall be neutral and impartial.

     2. The mediator shall control the procedural aspects of the mediation.  The
parties will cooperate fully with the mediator.


          (a)  The mediator is free to meet and communicate separately with each
               party.

          (b)  The  mediator  will decide when to hold joint  meetings  with the
               parties  and when to hold  separate  meetings.  There shall be no
               stenographic record of any meeting. Formal rules of evidence will
               not apply.

          (c)  The mediator  may request  that there be no direct  communication
               between  the  parties  or between  their  attorneys  without  the
               concurrence of the mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its  officers and an attorney.  Each party will have a  representative  fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator  will not transmit  information  received from any party to
another  party or any  third  person  unless  authorized  to do so by the  party
transmitting the information.

     6. The entire  process is  confidential.  The parties and the mediator will
not disclose information  regarding the process,  including settlement terms, to
third persons,  unless the parties otherwise agree. The process shall be treated
as a compromise  negotiation  for purposes of the Federal  Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing  administrative  and/or  judicial


                                       40
<PAGE>

remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

     (a)  The mediator will be disqualified  as a witness,  consultant or expert
          in any pending or future investigation,  action or proceeding relating
          to the subject matter of the mediation  (including any  investigation,
          action  or  proceeding  which  involves  persons  not  party  to  this
          mediation); and

     (b)  The mediator  and any  documents  and  information  in the  mediator's
          possession will not be subpoenaed in any such investigation, action or
          proceeding,  and all  parties  will  oppose  any  effort  to have  the
          mediator and documents subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.

     10. The mediator,  if a lawyer,  may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator  shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written  notice to the parties
(i) for overriding personal reasons,  (ii) if the mediator believes that a party
is not acting in good faith,  or (iii) if the  mediator  concludes  that further
mediation efforts would not be useful.

                                       41
<PAGE>

C. Binding Arbitration

     If the  parties do not resolve the  dispute  through  mediation  within the
period provided in Part A above,  the parties shall submit the matter to binding
arbitration before AAA, AAN or CPR, to a qualified sole arbitrator in accordance
with the then  current CPR Rules for  Non-Administered  Arbitration  of Business
Disputes or comparable  AAA or AAN rules.  The sole  arbitrator  shall be agreed
upon by the parties  within twenty (20) days after either party elects to submit
any issue to arbitration or, failing that, shall be selected by the organization
to whom the parties selected for arbitration.  A qualified arbitrator is one who
is familiar  with the  principal  subject  matter of the issues to be arbitrated
such as by way of example,  healthcare  services  industry  matters,  management
consulting  services  generally  or business  law/corporate  matters  generally.
Judgment upon the award  rendered by the  arbitrator may be entered in any court
having  jurisdiction.  The  arbitrator  shall  not have the  authority  to award
multiple,  punitive or  consequential  damages under any  circumstances.  If the
party initially raising the dispute to be resolved is New PC or Dr. Zapalac, the
arbitration shall be held in Boston,  Massachusetts,  and if the party initially
raising the dispute to be resolved is the MSO or OMEGA, the arbitration shall be
held in Austin, Texas.

above shall be deposited  into an account (the "the New PC Account") with a bank

     of such personnel; and

     (c) In the  event  the  funds in the New PC  Account  will,  at any time be
insufficient  to cover  the  current  portion  of the  foregoing  expenses  when
payable,  the  MSO may  advance  to the New PC the  necessary  funds  to pay the
current  portion of such expenses for the benefit of the New PC, which  advances
will be deemed to be loans to the New PC to be repaid without  interest from the
New PC Account at such times as there are  adequate  funds  therein or upon such
other  terms and at such  times as  agreed  to by the New PC and the MSO,  which
indebtedness shall not be deemed an MSO Expense for purposes of Section 2.9.

ability,  whether or not patients  can pay for services  rendered by the New PC,
either in cash or by  insurance.  Such  determination  shall be  subject  to the

Professions  Code  of  the  State  as it  relates  to  professional  orthodontic
practices.

ongoing basis.  Upon request of the New PC, the MSO will conduct a search for an
appropriate  orthodontist  and  other  professionals  (collectively,   "Practice
Associates") for the purposes of accommodating practice growth,  reducing doctor
work schedule,  or planned retirement.  Such search shall include use by the MSO
of a national  journal  advertising  program and networking in the profession to

responsible for interviewing and selecting each Practice Associate.

After the Practice  Associate(s)  is (are)  selected by the New PC, the MSO will
assist  the New PC with a trial  plan of  approximately  six  months for the new
Practice  Associate(s).  It is understood  that at the end of this period either
the New PC or the new Practice  Associate may terminate  the  relationship.  All
such Practice  Associates  recruited by the MSO as may be accepted by the New PC
shall be employees of the Practice (if so employed)  and not of the MSO. The MSO
will confer with the New PC on an appropriate salary/work-in arrangement for the
new Practice Associate and the final arrangements shall be determined by the New
PC.

     Notwithstanding the foregoing  provisions of this Section 2.19, the parties
agree that,  with respect to the  retirement of Dr.  Grove,  notice of which the
parties agree is hereby given, the following provisions shall apply:

     (a) Dr.  Grove and the MSO shall  begin  promptly  upon  execution  of this
Agreement to search for a qualified  Practice Associate to replace Dr. Grove and
each shall use all  reasonable  efforts in good faith to locate  candidates  for
such position;

     (b) The MSO will screen all candidates, whether located by Dr. Grove or the
MSO,  will not  unreasonably  withhold its approval of any  qualified  candidate
located by Dr. Grove and will present appropriate qualified candidates for final
selection by the New PC;

     (c) The New PC shall be  responsible  for  interviewing  and selecting each
candidate  to replace Dr.  Grove from the  candidates  presented by the MSO and,
once a candidate is selected,  Dr. Grove shall use all reasonable efforts to see
that such candidate successfully completes a six month trial period with the New
PC; and

     (d) It is understood  that at the end of this trial period,  either the New
PC or the candidate to replace Dr. Grove may terminate the relationship.  If the
relationship is terminated,  the search process  outlined in clauses (a) through
(d) of this Section 2.19 shall begin again.  Any  candidate to replace Dr. Grove
who is  accepted  by the New PC  shall be an  employee  of the  Practice  (if so
employed)  and  not of the  MSO.  The  MSO  will  confer  with  the New PC on an
appropriate   salary/work-in  arrangement  for  such  candidate  and  the  final
arrangements shall be determined by the New PC.

                              DUTIES OF THE NEW PC


     3.1 General.  The New PC shall be  responsible  for the  management  of its
practice and the Orthodontic  Office, in accordance with the requirements of the
Laws of the State.

     3.2 Employment of the  Orthodontists and Rendering of Patient Care. The New
PC shall be responsible for the employment and  professional  supervision of Dr.
Grove and all Orthodontists and the other Practice Providers and all orthodontic
care rendered to patients shall be rendered by Dr. Grove and such Orthodontists.
Additionally,  the New PC shall be responsible for the professional  supervision
of all other



                                       8
<PAGE>

Practice  Providers in their rendering of patient care.

     3.3 Professional  Services. The New PC shall use and occupy the Orthodontic
Offices  designated  on  Schedule  2 hereof  exclusively  for the  practice  and
rendering of orthodontic services, and shall comply with all applicable Laws and
all standards of orthodontic  care. It is expressly  acknowledged by the parties
that the  orthodontic  practice  conducted at the  Orthodontic  Offices shall be
conducted  solely by Dr.  Grove  and the  Orthodontists  and the other  Practice
Providers  acting  under  the  supervision  and  control  of the Dr.  Grove  and
Orthodontists (if any), and no other  orthodontist  shall be permitted to use or
occupy the Orthodontic Offices.  The New PC shall provide professional  services
to patients hereunder in compliance at all times with ethical standards and Laws
applying to the orthodontic  profession.  The New PC shall ensure that Dr. Grove
and each Orthodontist who provides  orthodontic services to patients is licensed
by the State. In the event that any disciplinary,  medical  malpractice or other
actions are initiated  against Dr. Grove or any  Orthodontist  or other Practice
Provider,  the New PC shall  immediately  inform the MSO of such  action and the
underlying facts and circumstances subject to such confidentiality  agreement or
arrangements  as the New PC and the MSO shall mutually  determine at or prior to
the time of such disclosure. The New PC agrees to cooperate with and participate
in  quality  assurance/utilization  review  programs  established  by the MSO or
mandated by accreditation and licensure standards  applicable to the practice of
orthodontics.  Deficiencies discovered in the performance of any personnel or in
the quality of professional  services shall be reported  immediately to the MSO,
and  appropriate  steps  shall  be taken  by the New PC at once to  remedy  such
deficiencies.

     3.4 Records.  The New PC will keep or cause to be kept  accurate,  complete
and timely  dental and other  records of all  patients.  The  management  of all
dental and patient  files and records  shall  comply  with all  applicable  Laws
regarding their confidentiality and retention and all files and records shall be
located so that they are readily  accessible for patient care,  consistent  with
ordinary  records  management  practices.  Such records  shall be  sufficient to
enable the MSO, on behalf of the New PC, to obtain  payments  for  services  and
related  charges and to facilitate  the delivery of quality  patient care by the
New PC.  Notwithstanding  the  foregoing,  patient  dental  records shall be and
remain the property of the New PC and the contents  thereof  shall be solely the
responsibility of the New PC.

     3.5 Professional  Expenses.  The New PC shall be solely responsible for the
cost of professional  licensure fees and board certification fees, membership in
professional associations and continuing professional education incurred by each
Orthodontist  and other  Practice  Provider  employed  by the New PC. The New PC
shall  ensure that Dr.  Grove and all the  Orthodontists  employed by the New PC
participate in such continuing  education as is necessary for Dr. Grove and such
the Orthodontists to remain current.

     3.6 Professional Liability Insurance.  The New PC shall provide, or arrange
for the  provision  of,  and  maintain  throughout  the Term of this  Agreement,
professional  liability  insurance coverage in accordance with the provisions of
Article 9 hereof. The New PC shall also cooperate in any programs recommended by
the MSO to assure  that each of its  Orthodontists  is  insurable,  and that Dr.
Grove and each participates in an on-going risk management program.

     3.7  Employment  Agreement.  The parties  recognize that the services to be
provided  by the  MSO  are  feasible  only  if the  New PC  operates  an  active
orthodontic practice to which it, Dr. Grove and each


                                       9
<PAGE>

Orthodontist  associated  with the New PC devote their full time and  attention,
unless other specific provisions are made in writing and mutually agreed upon by
the MSO  and  New PC.  The New PC will  cause  Dr.  Grove  and  each  individual
Orthodontist who now is or hereafter becomes affiliated with the New PC to enter
into a written employment agreement (the "Employment Agreement") satisfactory in
form and substance to the MSO,  pursuant to which Dr. Grove or the  Orthodontist
shall agree not to establish, operate or provide orthodontic or dental services,
without the prior written  consent of both the New PC and the MSO, at any office
or facility other than the  Orthodontic  Office.  In addition,  such  Employment
Agreement shall provide by its own terms or by a separate  agreement that if Dr.
Grove's or such Orthodontist's  employment shall terminate for any reason during
the Term of this  Agreement,  for a period of 24 months after the termination of
Dr.  Grove's or such  Orthodontist's  Employment  Agreement with the New PC, Dr.
Grove or such  Orthodontist  shall  agree not to  establish,  operate or provide
orthodontic or dental  services,  without the prior written  consent of both the
New PC and the MSO,  at any office  practice or  facility  whatsoever  providing
services similar to those provided by the New PC at any Dr. Grove or orthodontic
office within a fifteen (15) mile radius. Such Employment Agreement (or separate
agreement) shall also provide, among other things, that in the event of a breach
of Dr.  Grove's or the  Orthodontist's  agreement not to compete with the New PC
provided for in such Employment Agreement (or separate agreement), the MSO shall
be  entitled to receive,  in  addition  to other  remedies  and not by way of an
election  of  remedies,  liquidated  damages  equaling  the  greater of: (a) Dr.
Grove's or such Orthodontist's  income, as shown on the W-2 form prepared by the
New PC, for the most recent  calendar year; or (b) $300,000.  Such payment shall
be made to the MSO by the New PC  immediately  following  receipt of the payment
from Dr. Grove or the breaching  Orthodontist by the New PC. Each of the MSO and
OMEGA shall be expressly  named as a third-party  beneficiary to such agreements
between  the New PC and Dr.  Grove  and each  Orthodontist  and the  rights  and
remedies  of the MSO  and  OMEGA  thereunder  or  otherwise  in  respect  of the
restrictive  covenants set forth in such agreements shall survive termination of
this Agreement.

     3.8 Confidentiality.  The New PC agrees and acknowledges that all materials
provided by the MSO to the New PC constitute "Confidential  Information" and are
disclosed in confidence and with the understanding that it constitutes  valuable
business information  developed by the MSO with the assistance of OMEGA at great
expenditures of time,  effort and money. The New PC further agrees that it shall
not,  directly or indirectly,  without the express prior written  consent of the
MSO, use or disclose such Confidential Information for any purpose other than in
connection  with the  services  to be  rendered  hereunder.  The New PC  further
agrees:  (i) to keep strictly  confidential  and hold in trust all  Confidential
Information and not disclose such  Confidential  Information to any third party,
including its shareholders, directors, officers, affiliates, partners, employees
and  independent  contractors  without the express prior written  consent of the
MSO; and (ii) to impose this obligation of  confidentiality on its shareholders,
directors,   officers,   affiliates,   partners,   employees   and   independent
contractors.  The  New PC  acknowledges  that  the  disclosure  of  Confidential
Information  to it by the MSO is done in reliance upon its  representations  and
covenants in this Agreement. Upon expiration or termination of this Agreement by
either party for any reason whatsoever,  the New PC shall immediately return and
shall  cause  its  shareholders,   directors,  officers,  affiliates,  partners,
shareholders  and independent  contractors to immediately  return to the MSO all
Confidential  Information,  and  the  New  PC  will  not,  and  will  cause  its
affiliates,  partners,  employees and independent contractors not to, thereafter
use, appropriate, or reproduce such Confidential Information. The New PC further
expressly   acknowledges  and  agrees  that  any  such  use,   appropriation  or
reproduction of any such Confidential  Information by any of the foregoing after
the  expiration or  termination  of this  Agreement  will result in  irreparable
injury to the MSO and OMEGA,  that the remedy at law for the foregoing



                                       10
<PAGE>

would be inadequate,  and that in the event of any such use,  appropriation,  or
reproduction  of any such  Confidential  Information  after the  termination  or
expiration  of this  Agreement,  the MSO and  OMEGA,  in  addition  to any other
remedies or damages  available  to either or both of them,  shall be entitled to
injunctive or other  equitable  relief  without the necessity of proving  actual
damages  but such  rights to relief  shall not  preclude  the MSO and OMEGA from
other remedies which may be available to either or both of them hereunder.

                 PROFESSIONAL SERVICES, CONTROL OF SOLICITATION,
              APPROVAL OF ADVERTISING MATERIAL AND NO RECIPROCATION


     4.1 A  fundamental  understanding  between the  parties  hereto is that the
rendering of  orthodontic  services shall be separate and  independent  from the
provision of  administrative,  management and support services by the MSO. Thus,
the  New PC  shall  have  sole  and  absolute  control  of the  delivery  of all
professional  services  and  treatment  rendered to patients at the  Orthodontic
Offices.

     4.2 No employee or other  representative of the MSO shall be engaged in, or
allowed to solicit patients on behalf of, the New PC, nor shall the MSO have any
control over the New PC's patients.

     4.3 No  advertising  or promotional  materials,  or other  materials of any
nature,   including   billing  and  collection   forms,   reports,   agreements,
correspondence,  or similar materials,  used in connection with the New PC shall
be used or distributed without having first been approved by the New PC.

     4.4 The parties hereby  acknowledge  and agree that the benefits  conferred
upon each of them hereunder  neither  require nor are in any way contingent upon
the  admission,  recommendation,  referral,  or any  other  arrangement  for the
provision  of any item or service  offered by the MSO to any patients of the New
PC or its shareholders,  officers, directors, employees,  contractors or agents,
nor are such benefits in any way contingent upon the recommendation, referral or
any other  arrangement  for the provision of any item or service  offered by the
New PC or any of its Practice Providers, employees, contractors or agents.

     5.1 In  consideration  of the sums to be paid to the MSO under the terms of
this Agreement, the MSO hereby leases or sub-leases,  as applicable,  to the New
PC during the Term of this Agreement the Orthodontic  Offices, and the leasehold
improvements and fixtures, furniture and equipment at the Orthodontic Offices as
listed from time to time on Schedule 2 attached hereto and  incorporated  herein
by this reference, under the following terms and conditions:

     (a) The MSO is the  lessee  by  assignment  under  lease  for the  premises
occupied by the New PC  (collectively,  the  "Master  Lease") a copy of which is
attached hereto as Exhibit A and incorporated herein by this reference.  The New
PC hereby  acknowledges  that the premises  described under the Master Lease are
suitable for the New PC's  orthodontic  practice.  Based and contingent upon the
New PC's  promise to timely pay all  amounts due under this  Agreement,  the MSO
hereby  agrees to sublease the leased  premises to the New PC upon the following
terms and conditions:

          (i) This sublease between the MSO and the New PC of the premises shall
     be subject to all of the terms and  conditions of the Master Lease.  In the
     event of the  termination  of the MSO's interest as lessee under the Master
     Lease for any reason, then the sublease created hereby shall simultaneously
     terminate, unless the New PC assumes the obligations under the Master Lease
     in question and the Lessor consents thereto.

          (ii) All of the terms and conditions contained in the Master Lease are
     incorporated  herein as terms and  conditions  of the  sublease  (with each
     reference  therein to "Lessor"  and  "Lessee," to be deemed to refer to the
     MSO and the New PC,  respectively)  and,  along with the provisions of this
     Section  5.1(b) and Exhibit "A," shall be the complete terms and conditions
     of the sublease created hereby.

          (iii)  Notwithstanding  the foregoing,  as between the MSO and the New
     PC,  the MSO shall  remain  responsible  for  meeting  the  obligations  of
     "Lessee" under the sections  entitled  Rent,  Additional  Rent  Adjustment,
     Insurance  on  Fixtures,  Liability  Insurance,  Repairs,  and Taxes of the
     Master Lease,  all of which  obligations  shall be considered  MSO Expenses
     hereunder and the New PC shall have no monetary  obligation in that regard.
     In  addition,  as between the MSO and the New PC, the MSO shall  retain the
     right to exercise any options to purchase the  premises,  or other  similar
     rights of ownership or  possession,  which may be granted  under the Master
     Lease, and the New PC shall have no rights in that regard.

          (iv) In the event this Agreement is terminated according to its terms,
     this sublease shall also terminate automatically.

          (v) If the Master Lease contains an option to renew the terms thereof,
     the MSO shall  notify the New PC, at least 30 days prior to the  expiration
     of the time for exercising such option,  of




                                       12
<PAGE>

     the  MSO's  intention  to  renew  or not to  renew  such  term.  If the MSO
     determines not to renew such term, the MSO shall provide or arrange for the
     provision of comparable office space (the "Substitute  Orthodontic Office")
     within a radius of 15 miles of the  Orthodontic  Office,  which  Substitute
     Orthodontic  Office  shall be subject to the  approval of the New PC (which
     approval  shall not be  unreasonably  withheld  or  delayed).  The lease or
     sublease for such Substitute  Orthodontic  Office, as applicable,  shall be
     substituted  for the lease described on Exhibit A hereto and all references
     to the  "Master  Lease"  shall  thereafter  be  applicable  to the lease or
     sublease  for  the  Substitute  Orthodontic  Office  for  purposes  of this
     Agreement, ab initio.

          (vi)  The  Alternative  Dispute  Resolution  provisions  set  forth in
     Article 14 of this Agreement  shall not apply to any issues  concerning the
     Sub-Lease,  the New PC's  tenancy  or the  MSO's  rights  and  remedies  as
     Sub-Lessor.

     5.2 The  MSO  shall  provide  the New PC at the  Orthodontic  Offices  such
additional  leasehold  improvements,   fixtures,   furniture,   furnishings  and
equipment as may be mutually  agreed to with the New PC and reflected  from time
to time on a  supplement  to  Schedule  2  hereto.  The use by the New PC of all
leasehold improvements,  fixtures, furniture, furnishings and equipment provided
hereunder shall be subject to the following conditions:

     (a)  Title  to all  such  leasehold  improvements,  fixtures,  furnishings,
furniture and  equipment  shall remain in the MSO and upon  termination  of this
Agreement,  the New PC shall immediately return and surrender all such leasehold
improvements,  fixtures,  furniture,  furnishings and equipment to the MSO in as
good condition as when received, normal wear and tear excepted.

     (b) The MSO shall be fully and  entirely  responsible  for all  repairs and
maintenance of all such leasehold improvements, fixtures, furniture, furnishings
and equipment;  provided,  however,  that the New PC agrees that it will use its
best  efforts to prevent  damage,  excessive  wear,  and  breakdown  of all such
leasehold  improvements,  fixtures,  furniture,  furnishings and equipment,  and
shall advise the MSO of any and all needed repairs and equipment failures.

     (c)  The  obligation  of the MSO to  provide  the  leasehold  improvements,
fixtures, furniture, furnishings and equipment stated herein shall be concurrent
and co-extensive with the Term of this Agreement.

     5.3. No Warranty.

     (a)  THE  NEW  PC  ACKNOWLEDGES   THAT  THE  MSO  MAKES  NO  WARRANTIES  OR
REPRESENTATIONS,  EXPRESS OR IMPLIED,  AS TO THE  SUITABILITY OR ADEQUACY OF ANY
LEASEHOLD IMPROVEMENTS,  FIXTURES, FURNITURE, FURNISHINGS,  EQUIPMENT, INVENTORY
OR SUPPLIES  PROVIDED OR LEASED OR SUBLEASED  PURSUANT TO THIS AGREEMENT FOR THE
CONDUCT OF AN ORTHODONTICS PRACTICE OR FOR ANY OTHER PARTICULAR PURPOSE.

     (b) Nothing in this Agreement  shall be construed to affect or limit in any
way the  professional  discretion  of the  Practice  Providers to select and use
fixtures, furniture, furnishings and equipment, inventory and supplies purchased
or provided  by the MSO in  accordance  with the  provisions  of this  Agreement
insofar as such selection or use constitutes or might constitute the practice of
dentistry or orthodontistry.

                                  COMPENSATION

     As  consideration  for the performance of all of its duties and obligations
as  provided  in this  Agreement,  including  but not  limited to, the costs and
expenses  associated  with  furnishing  the  services,  personnel,   facilities,
leasehold improvements, fixtures, furniture, furnishings, equipment, inventories
and supplies provided for herein, the MSO shall receive compensation in the form
of monthly  management fees (the  "Management  Fees") based upon a predetermined
percentage of the "Practice  Revenues",  as defined and determined in accordance
with the  provisions  set forth in Schedule 3 attached  hereto and  incorporated
herein by this reference,  as such Schedule may be amended by the New PC and the
MSO from time to time. It is acknowledged by and between the parties hereto that
the MSO and/or its  affiliates  has (have)  incurred  substantial  expenses  and
future  obligations  in  acquiring  the capital  stock of the MSO,  acquiring or
otherwise  establishing  the  Orthodontic  Offices,  establishing  its  systems,
including fees for consultants and other professionals,  interest expense, lease
obligations,  and costs of furnishing or refurbishing  the premises at which the
Orthodontic   Offices  are  located.   The  MSO  has  also  assumed  substantial
obligations associated with the continuing operation of the Orthodontic Offices,
including  those of  lessee,  obligor  and  guarantor  and  obligor  on loans to
establish and operate the Orthodontic  Offices. The parties,  therefore,  having
considered various  compensation  formulae,  acknowledge and agree that in order
for the MSO to  receive  a fair  and  reasonable  return  for its  expenses  and
obligations,  and a fair return for the lease of the premises and  equipment and
for providing the services contemplated hereunder,  that the agreed compensation
is not excessive.  The New PC acknowledges that the compensation  arrangement is
reasonable  under the  circumstances  noted herein and has executed an Affidavit
attesting  to this fact  which is  attached  hereto and  incorporated  herein as
Exhibit C. In consideration of the foregoing, the parties agree that the monthly
Management Fees payable to the MSO by the New PC for services  rendered pursuant
to this  Agreement  shall be reviewed and subject to  adjustment at the close of
each  year of the  Term of this  Agreement  based  upon  industry  standards  of
practice and the MSO's costs in performing the required services. If the parties
cannot agree within  thirty (30) days prior to the close of any such year on the
terms of any adjustment to the Management  Fees for the following year, then the
then existing  Management  Fees shall remain in effect.  The New PC specifically
agrees  that the MSO may defer  actual  receipt of its  Management  Fees  and/or
advance  monies for purposes of managing the New PC's cash flow, and the MSO may
repay itself such  advances or pay said deferred  Management  Fees when it deems
appropriate.

                                SECURITY INTEREST


     As  assurance  and  collateral  security  for the  payment  of the  monthly
Management  Fees  owed  to the

MSO pursuant to this Agreement and any funds advanced by the MSO to or on behalf
of the New PC  pursuant  to this  Agreement  and for  the  faithful  and  timely
performance  of all the covenants  and  conditions to be performed by the New PC
under this Agreement, the New PC hereby pledges,  grants, bargains,  assigns and
transfers  to the MSO a security  interest,  pursuant to the Uniform  Commercial
Code of the State,  in and to all Practice  Revenue and accounts  receivable  of
patients of the New PC, together with all proceeds  thereof  (collectively,  the
"Collateral"),  and further agrees not to pledge, assign, transfer or convey any
of the Collateral or any proceeds  therefrom,  without the prior written consent
of the MSO,  except to affiliates of the MSO.  Concurrent  with the execution of
this Agreement,  the New PC shall execute a Security Agreement,  similar in form
and content as that attached hereto as Exhibit D and incorporated herein by this
reference in order that the MSO may perfect its interest in the Collateral.  The
New PC expressly agrees to execute any appropriate UCC-1 Financing Statement and
UCC-1 Fixture filings, if so requested in writing by the MSO.

                                    COVENANTS


     8.1 New PC's Covenants.  As further consideration for the MSO's performance
of the terms and conditions of this Agreement, the New PC covenants,  represents

orthodontic care provided.

     (c) During the Term of this  Agreement,  the New PC shall not,  directly or
indirectly,  own an interest in, operate,  join,  control,  participate in or be
connected in any manner with any corporation, partnership, proprietorship, firm,
association, person or entity providing orthodontic care in competition with the
practice at the Orthodontic  Offices, or any other orthodontic  practice managed
by the MSO,  within a radius  of 15 miles of the  Orthodontic  Office or of such
other orthodontic practice, without the MSO's prior written consent.

     (d) The New PC recognizes the  proprietary  interest of OMEGA in and to its
OMEGA  Patient  Scheduling  System and the MSO in its systems for  managing  the
delivery of orthodontic care and all policies,  procedures,  operating  manuals,
forms,  contracts and other information  (collectively,  the "MSO  Information")
regarding such system.  The New PC acknowledges  and agrees that all information
relating  to the  OMEGA  Patient  Scheduling  System  and  the  MSO  Information
constitutes  trade secrets of OMEGA and/or the MSO. The New PC hereby waives any
and all right,  title and  interest  in and to such trade  secrets and agrees to
return all copies of such trade secrets and information relating thereto, at its
expense, upon termination of this Agreement.



                                       15
<PAGE>

     (e) The New PC acknowledges  and agrees that OMEGA and the MSO are entitled
to prevent their  respective  competitors  from  obtaining  and utilizing  their
respective trade secrets.  The New PC agrees to hold OMEGA'S and the MSO's trade
secrets in  strictest  confidence  and not to disclose  them or allow them to be
disclosed  directly or indirectly to any person or entity other than persons who
are engaged by the New PC to perform  duties in  connection  with the New PC and
who have a need to know such trade  secrets in the  performance  of their duties
for the New PC, without OMEGA's or the MSO's prior written consent,  as the case
may be. The New PC acknowledges  its fiduciary  obligations to OMEGA and the MSO
and the  confidentiality  of its relationships with OMEGA and the MSO and of any
information  relating to the services and business  methods of OMEGA and the MSO
which it may  obtain  during the term of this  Agreement.  The New PC shall not,
either during the term of this  Agreement or at any time after the expiration or
sooner  termination  hereof,   disclose  to  anyone,  other  than  employees  or
independent  contractors  of OMEGA  and the MSO who use  OMEGA's  and the  MSO's
system in the course of the  performance of their duties,  any  confidential  or
proprietary information or trade secrets obtained by the New PC. The New PC also
agrees to place  any  persons  to whom said  information  is  disclosed  for the
purpose of  performance  under legal  obligation  to treat such  information  as
strictly confidential.

     8.2 MSO's Covenants.  As further consideration for the New PC's performance
of the terms and conditions of this Agreement, the MSO covenants, represents and
warrants  (which  covenants,  representations  and warranties  shall survive the
execution of this  Agreement)  that during the Term of this  Agreement,  the MSO
agrees not to  establish,  develop or open any  offices in  affiliation  with an
orthodontist  for the provision of orthodontic  services within a 15 mile radius
of the Orthodontic Offices, without the express written consent of the New PC.

                             INSURANCE AND INDEMNITY

     9.1 Insurance to be Maintained by the New PC.  Throughout  the Term of this
Agreement,  the New PC shall  maintain  in full force and  effect  comprehensive
professional  liability  insurance  with  limits of not less than  $500,000  per
occurrence  and  $1,000,000  annual  aggregate  per Dr.  Grove  and  each of the
Orthodontist  providing services for the New PC and a separate limit for the New
PC. The New PC shall be responsible for all liabilities  within  deductibles and
for all liabilities in excess of the limits of such policies.  The MSO agrees to
negotiate for and cause premiums to be paid on behalf of the New PC with respect
to such insurance.  Premiums and deductibles with respect to such policies shall
not be MSO  Expenses.  The  New PC also  agrees  to name  the MSO and  OMEGA  as
co-insureds.  The New PC agrees to deliver to the MSO and OMEGA a certificate of
insurance indicating such coverage.

     9.2  Insurance to be  Maintained  by the MSO.  Throughout  the Term of this
Agreement, the MSO will use reasonable efforts to provide and maintain, as a MSO
Expense, (a) comprehensive professional liability insurance for all professional
employees of the MSO with limits as  determined  reasonable  by the MSO; and (b)
comprehensive  general liability and property insurance covering the Orthodontic
Office premises and operations.

     9.3 Tail  Insurance  Coverage.  The New PC will  cause  Dr.  Grove and each

PC that upon termination of Dr. Grove's or


                                       16
<PAGE>

such Orthodontist's relationship with the New PC, for any reason, tail insurance
coverage will be purchased by Dr. Grove or such  Orthodontist.  Such  provisions
may be contained in an employment  agreement,  restrictive covenant agreement or
other  agreement  entered into by the New PC and Dr. Grove or the  Orthodontist,
and the New PC hereby covenants with the MSO to enforce such provisions relating
to the tail insurance coverage or to provide such coverage at the expense of the
New PC or Dr. Grove or each such Orthodontist.

     9.4  Additional  Insureds.  The  New PC and  the  MSO  agree  to use  their
reasonable  efforts to have each  other  named as an  additional  insured on the
other's respective liability insurance policies.

     9.5 Indemnification.  The New PC shall indemnify,  hold harmless and defend
the MSO and  OMEGA  and  their  respective  officers,  directors,  shareholders,
employees and representatives,  from and against any and all liability,  losses,
damages, claims, causes of action, expenses judgments, settlements, lawsuits and
obligations  (including  reasonable  attorneys' fees), whether or not covered by
insurance, caused or asserted to have been caused, directly or indirectly, by or
as a result of the performance of orthodontic services or the performance of any
intentional  acts,  negligent  acts  or  omissions  by  the  New PC  and/or  its
affiliates,  its  shareholders,   agents,  the  Practice  Providers,  its  other
employees and/or its subcontractors (other than the MSO) during the Term hereof.
The MSO shall  indemnify,  hold  harmless  and defend the New PC, its  officers,
directors,  shareholders and employees,  from and against any and all liability,
loss,  damage,  claim,  causes of action,  and  expenses  (including  reasonable
attorneys'  fees),  caused  or  asserted  to  have  been  caused,   directly  or
indirectly,  by or as a  result  of the  performance  of any  intentional  acts,
negligent  acts  or  omissions  by the  MSO  and/or  its  shareholders,  agents,
employees and/or subcontractors (other than the New PC) during the Term hereof.

the  Management  Fees  collected to the effective  date of such  termination  or

unpaid  interest  thereon) and all other sums accrued or related to  occurrences
arising at or prior to the date of termination.


                                   ARTICLE 11
                     AUTHORIZED AGENT AND POWERS OF ATTORNEY

     The New PC hereby  designates  the MSO (and its  designees)  its authorized
agent and lawful  attorney-in-fact for purposes of depositing  payments,  paying
accounts  payables,  signing  checks,  negotiating  and  signing  contracts  for
services or goods,  securing loans or incurring obligations on behalf of the New
PC; provided,  however, that all contracts or fees set for services on behalf of
the New PC will be  subject  to final


                                       18
<PAGE>

approval  and  acceptance  by the  New  PC.  Additionally,  the  New  PC  hereby
irrevocably appoints the MSO (and its designees) its authorized agent and lawful
attorney-in-fact  to collect all bills and accounts  receivable for professional
fees,  charges and other amounts and authorizes the MSO through its designees to
take possession of all checks,  money orders and similar instruments received as
payment of  receivables  to be  deposited  into the New PC  Account.  The New PC
hereby irrevocably appoints the MSO as the New PC's attorney-in-fact,  with full
power  and  authority  in the  place  and  stead  of the  New PC,  in the  MSO's
discretion,  to endorse in the name of the New PC any checks,  payments,  notes,
insurance payments and money orders, to withdraw funds for payments of expenses,
including  Management  Fees and other sums payable to the MSO, to open and close
the New PC Account  and other bank  accounts,  to take any action and to execute
any other instrument which the MSO may deem necessary or advisable to accomplish
the purposes  hereof.  The powers of attorney granted herein are coupled with an
interest and are irrevocable. Third parties and entities and persons not a party
to this Agreement are entitled to rely on the foregoing attorneys-in-fact and an
affidavit of the MSO attesting  thereto.  The acceptance of this  appointment by
the MSO shall not  obligate it to perform  any duty or  covenant  required to be
performed  by the New PC under or by virtue of this  Agreement.  Notwithstanding
the foregoing  powers of attorney,  the New PC shall at any time, on the request
of the MSO, sign financing  statements,  security agreements or other agreements
necessary or advisable to accomplish the purpose of this Agreement. Upon the New
PC's failure to sign said  financing  statements,  security  agreements or other
agreements,  the MSO is  authorized  as the agent of the New PC to sign any such
instruments. The New PC may review all deposits and expenses upon request.

                                   ARTICLE 12
                       INDEPENDENT CONTRACTOR RELATIONSHIP


     Neither  the New PC nor its  employees  shall  have any  claim  under  this
Agreement or otherwise against the MSO for worker's  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 the New PC. Since  neither the New PC nor its  employees  are
employees  of the MSO,  the MSO  shall  not  withhold  on  behalf  of the New PC
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 the New PC.

                                   ARTICLE 13
                                 MISCELLANEOUS


     13.1 Access to Records.  From and after any  termination,  each party shall
provide the other party with  reasonable  access to books and records then owned
by it to permit  such  requesting  party to satisfy  reporting  and  contractual
obligations which may be required of it.

     13.2 Patient Records. Upon termination of this Agreement,  the New PC shall
retain all patient  dental  records  maintained  by the New PC or the MSO in the
name of the New PC. During the term of this Agreement,  and thereafter,  the New
PC or its designee shall have reasonable  access during normal business hours to
the New PC's and the MSO's  records,  including,  but not limited to, records of
collections,  expenses and 


                                       19
<PAGE>

disbursements as kept by the MSO in performing the MSO's  obligations under this
Agreement, and the New PC may copy any or all such records.

     13.3 The New PC's Control Over the  Orthodontic  Practice.  Notwithstanding
the authority  granted to the MSO herein,  the MSO and the New PC agree that the
New PC, personally or through Dr. Grove or any of its Orthodontists (if any) and
other Practice  Providers,  shall have complete control and supervision over the
professional  aspects of the New PC's practice,  as well as the provision of all
professional services,  including, without limitation, the selection of a course
of treatment for a patient,  the procedures or materials to be used as a part of
such course of  treatment,  and the manner in which such course of  treatment is
carried  out by the New PC. The New PC shall have sole  authority  to direct the
business, professional, and ethical aspects of the New PC. The MSO shall have no
authority,  directly or  indirectly,  to  perform,  and shall not  perform,  any
orthodontic  function,  or to influence or otherwise interfere with the exercise
of the New PC's professional judgment.  The MSO may, however,  advise the New PC
as to the relationship between its performance of orthodontic  functions and the
overall administrative and business functioning of the New PC.

                         ALTERNATIVE DISPUTE RESOLUTION

     14.1 Alternative Dispute Resolution

     (a) If a dispute  arises  under this  Agreement  which  cannot be  resolved
informally  by the  parties,  any party may invoke the  procedures  set forth in
Exhibit E hereto and the parties agree to use these procedures, except paragraph
(b) of this Section 14.1, prior to any party pursuing other available  remedies.
The parties  will meet and attempt in good faith to resolve any  controversy  or
claim arising out of or relating to this Agreement.

     (b) Notwithstanding anything in this Section 14.1 to the contrary:

          (i) Nothing in this Section 14.1 shall preclude any party from seeking
     a preliminary  injunction or other provisional  relief,  either prior to or
     during the proceeding provided for in this section, if in its judgment such
     action is necessary to avoid  irreparable  damage or to preserve the status
     quo.

          (ii)  The  parties  shall  accept  as  correct,   final,  binding  and
     conclusive the  determination  by the outside  accountants then employed by
     the MSO as to the  calculation of any and all  Management  Fees owed by the
     New PC to the MSO hereunder, and such determination shall not be subject to
     the   provisions  of  this  Section   14.1.   Disputes  as  to  the  proper
     interpretation of the provisions of this Agreement which describe how those
     amounts are to be calculated,  however,  shall be subject to the provisions
     of this Section 14.1.

          (iii) Any determination by either party not to renew this Agreement in
     accordance  with the terms and  provisions of this  Agreement  shall not be
     subject to the provisions for dispute resolution in this Section 14.1.

     14.2  Waiver of Jury.  With  respect  to any  dispute  arising  under or in
connection  with this  Agreement  or any  related  agreement,  as to which legal
action  nevertheless  occurs, each party hereby irrevocably waives all rights it
may have to demand a jury trial.  This waiver is  knowingly,  intentionally  and
voluntarily  made by the  parties  and each  party  acknowledges  that no person
acting  on behalf of the  other  party  has made any  representation  of fact to
induce this  waiver of trial by jury or in any way  modified  or  nullified  its
effect.  The parties each further  acknowledge  that it has been represented (or
has had the  opportunity to be represented) in the signing of this Agreement and
in the making of this waiver by independent  legal counsel,  selected of its own
free will,  and that it has had the  opportunity  to discuss  this  waiver  with
counsel.  Each party further  acknowledges  that it has read and understands the
meaning and ramifications of this waiver provision.

                                   ARTICLE 15
                               GENERAL PROVISIONS

     15.1 Notices.  Any notice to be given pursuant to this  Agreement  shall be
deemed  effective if given  personally,  or by  telephone,  telegram,  telecopy,
facsimile  or other  electronic  transmission,  or by  letter to an  officer  or
administrator  of OMEGA,  the MSO or the New PC,  as the case may be.  Notice in
person,  or by telephone,  telegram or electronic  transmission  shall be deemed

hours after  deposit in the United  States mails,  and properly  addressed  with

or such other  address as may be furnished by the New PC to the MSO from time to
time in writing.

         Notices to OMEGA and/or the MSO shall be given as follows:

         Attn: Robert Schulhof


or other such  addresses  as may be furnished by the MSO to the New PC from time
to time in writing.

     15.2  Confidentiality.  No party hereto shall disseminate or release to any
third party any information  regarding any provision of this  Agreement,  or any
financial information regarding the other parties (past, present or future) that
was obtained in the course of the negotiation of this Agreement or in the course
of




                                       21
<PAGE>

the performance of this Agreement, without the other party's or parties' (as the
case may be) written approval;  provided, however, the foregoing shall not apply
to information  which is required to be disclosed by Law,  including  federal or
state securities laws, or pursuant to court order.

     15.3 Contract  Modifications for Prospective Legal Events. In the event any
state or  federal  Laws,  now  existing  or  enacted  or  promulgated  after the
effective  date of this  Agreement,  are  interpreted  by judicial  decision,  a
regulatory  agency  or legal  counsel  for both  parties  in such a manner as to
indicate that the structure of this  Agreement may be in violation of such Laws,
the New PC and the MSO shall amend this  Agreement as necessary.  To the maximum
extent possible,  any such amendment shall preserve the underlying  economic and
financial arrangements between the New PC and the MSO.

     15.4  Remedies  Cumulative.  No  remedy  set  forth  in this  Agreement  or
otherwise conferred upon or reserved to any party shall be considered  exclusive
of any other  remedy  available  to any party,  but the same shall be  distinct,
separate  and  cumulative  and may be  exercised  from  time to time as often as
occasion may arise or as may be deemed expedient.

     15.5 No Obligation to Third Parties.  None of the obligations and duties of
the MSO or the New PC under this Agreement  shall in any way or in any manner be
deemed to create  any  obligation  of the MSO or of the New PC to, or any rights
in, any person or entity not a party to this  Agreement  other than OMEGA  which
shall be deemed a party for limited purposes as set forth in this Agreement.

     15.6 Entire Agreement.  This Agreement including the Schedules and Exhibits
hereto,  together  with the Stock  Put/Call  Option  and  Successor  Designation
Agreement of even date herewith and the Employment  Agreement(s)  (including the
related  non-competition  agreements  or  covenants),   constitutes  the  entire
agreement between the parties concerning this subject matter, and supersedes all
prior and contemporaneous agreements,  representations and understandings of the
parties  concerning  the  contents  hereof.  No  supplement,   modification,  or
amendment to this Agreement  shall be binding unless  executed in writing by all
of the parties hereto,  except as otherwise provided herein. No waiver of any of
the provisions of this  Agreement  shall be deemed to constitute a waiver of any
other provision, whether similar or not similar, nor shall any waiver constitute
a continuing  waiver.  No waiver shall be binding unless  executed in writing by
the party making the waiver.

     15.7  Assignment.  The  rights  and the  duties of the  parties  under this
Agreement may not be assigned or transferred  without the prior written  consent
of the non-assigning  party,  which consent shall not be unreasonably  withheld;
provided,  however,  that the MSO shall be  permitted  to assign  its rights and
obligations  hereunder without the consent of the New PC to any person,  firm or
corporation  controlled by the MSO,  controlling the MSO or under common control
with the MSO.

     15.8 Attorneys' Fees. If any mediation or arbitration or other legal action
or  proceeding  is brought to enforce  this  Agreement,  because of any  alleged
breach hereof, or for a declaration of any rights and obligations hereunder, the
prevailing party in such mediation or arbitration, action or proceeding shall be
entitled to recover its costs incurred therein,  including reasonable attorneys'
fees,  in  addition  to any  other  relief to which it may be  entitled,  all as
determined  and awarded by the parties in such mediation or by the arbitrator or
court as




                                       22
<PAGE>

part of its judgment or decision therein, as the case may be.

     15.9 Governing  Law. This  Agreement  shall be governed by and construed in
accordance with the laws of the State.  The parties  acknowledge that the MSO is
not  authorized or qualified to engage in any activity which may be construed or
deemed to constitute  the practice of dentistry or  orthodontics.  To the extent
any act or service  required of the MSO in this Agreement should be construed or
deemed,  by any  governmental  authority,  agency  or  court to  constitute  the
practice of dentistry or orthodontics, the performance of said act or service by
the MSO shall be deemed waived and forever  unenforceable  and the provisions of
Section 15.14 shall be applicable.

     15.10 Events  Excusing  Performance.  Neither  party shall be liable to the
other party for failure to perform any of the  services  required  herein in the
event of strikes, lock-outs, calamities, acts of God, unavailability of supplies
or other  events over which that party has no control for so long as such events
continue, and for a reasonable period of time thereafter.

     15.11  Compliance with Applicable  Laws. Both parties shall comply with all
applicable  Laws and  restrictions  imposed  thereunder  in the conduct of their
obligations under this Agreement.

     15.12 Language  Construction.  The parties  acknowledge that each party and
its counsel have reviewed and revised this Agreement and that the normal rule of
construction to the effect that any  ambiguities are to be resolved  against the
drafting party shall not be employed in the interpretation of this Agreement.

     15.13 Amendments. This Agreement may be amended only by the written consent
of both parties.

     15.14 Severability. In the event any provision of this Agreement is held by
a court of  competent  jurisdiction  to be  illegal  or  unenforceable,  (i) the
parties  shall  amend  this  Agreement  in  order to carry  out the  intent  and
essential  business  purposes of this Agreement as closely  possible  within the
requirements of applicable  provisions of Law as determined by such a court, and
(ii) the remaining provisions of this Agreement shall continue in full force and
effect.

     15.15 No Waiver. The waiver by either party to this Agreement of any one or
more defaults, if any, on the part of the other party, shall not be construed to
operate as a waiver of the other or future defaults under this Agreement.

     15.16  Captions.  Captions to paragraphs in this  Agreement are for ease of
reference, and shall not be considered an interpretation of the paragraph.

     15.17 Counterparts. This Agreement may be executed simultaneously in one or
more counterparts, each of which shall be deemed an original.

     IN WITNESS  WHEREOF,  the parties hereto have executed this agreement as of
the day and year first above written.

                         COMPENSATION - MANAGEMENT FEES


     The MSO shall receive,  as  compensation  for the performance of all of its
obligations and duties contained in the Agreement, monthly Management Fees in an
amount equal to ___ Percent ( %) of the Practice Revenues,  and the New PC shall
be entitled to ___ Percent ( %) of such Practice Revenues, except as the parties
may otherwise agree from time to time in writing. At the end of each twelve (12)
month period  during the Term the MSO shall provide the New PC with an unaudited
internal accounting of the MSO Expenses, prepared in accordance with the accrual
method of  accounting.  If the MSO Expenses as reflected in such  accounting  as
having  been paid by the MSO are less than sixty (60%)  percent of the  Practice
Revenues for such twelve month period,  fifty (50%)  percent of such  difference
shall be  returned  by the MSO to the New PC as a profit  incentive  rebate (the
"Rebate").  If the  Agreement to which this Schedule 3 is attached is terminated
or expires,  the foregoing  Management Fees shall be payable to the MSO based on
all Practice Revenue collected as of the date of termination or expiration.

     Payment  to the MSO  shall  be made in  monthly  installments  based on the
Practice Revenues realized by the MSO for services rendered  hereunder.  The MSO
shall  distribute the proceeds from the New PC Account and allocate the proceeds
between the MSO and the New PC as described  above, on or before the 15th day of
the succeeding  month.  In the event the 15th day falls on a weekend or holiday,
then said  distribution  shall be made on the next  business  day.  The  parties
hereto may agree to handle such matters in a different manner.

     For  purposes  of this  Agreement,  "Practice  Revenues"  shall  mean gross
collections  of all  revenues  generated  by or on behalf of the New PC (whether
through subsidiaries or affiliates), including, but not limited to, all fees and
charges collected as a result of professional  orthodontic services furnished to
patients by the New PC and for any other  goods or services  sold or provided to
such patients.

AFFIDAVIT


     I, David T. Grove, D.M.D., M.S., declare:

     I am an  orthodontist,  duly licensed in the State of Nevada and I practice
through a professional corporation under the name ______________ (the "New PC").

     I have had substantial  experience in the practice of the  Orthodontics and
in managing and operating an orthodontic office.

     In the course of operating orthodontic offices, I have acquired significant
knowledge as to the overhead  costs  incurred  and gross  receipts  generated by
similar  types  of  orthodontic  offices.  Further,  I am  fully  aware  of  the
non-orthodontic,  operational,  accounting,  billing, financing,  management and
personnel requirements of an orthodontic office and the cost factors involved in
providing  such  management,   personnel,  accounting,  billing,  financing  and
operation.

     I  have  thoroughly   reviewed  the  Management   Services  Agreement  (the
"Agreement"), which is effective as of ________________,  199__, between the New
PC and Omega  Orthodontics  of Elko,  Inc.  (the "MSO")  concerning  the duties,
responsibilities and obligations undertaken by the MSO in managing and operating
all  non-orthodontic  aspects of the  Orthodontic  Office as contemplated by the
Agreement.

     I have reviewed the prior operating financial statements of the orthodontic
office located at 581 12th Street,  Elko,  Nevada 89801, and an operating budget
and  estimated  income of the  orthodontic  office,  which,  in my opinion,  can
reasonably be expected from the operation of said office.

     In my  opinion,  based  upon my  experience,  the  Management  Fees of ____
Percent (___%) of "Practice  Revenues" to be charged by the MSO as  contemplated
by the Agreement,  will afford it a reasonable but not excessive  return for its
services rendered and obligations incurred. In addition, the New PC ____ Percent
( %) of  "Practice  Revenues"  retained by the New PC, will  provide  reasonable
earnings for the performance of orthodontic services.

     I declare under penalty of perjury that the foregoing statement is true and
correct to the best of my knowledge and belief.

     Executed at ________________, ________ this day of                 , 199__.

                               SECURITY AGREEMENT


     THIS  SECURITY  AGREEMENT  is  effective  as of the ______ day of _________
199____, by _____________________,  PC, a Nevada corporation (the "New PC"), and
David T. Grove,  D.M.D.,  M.S.  ("Dr.  Grove") who is duly  licensed to practice
orthodontics  in the State and Omega  Orthodontics  of Elko,  Inc.,  a  Delaware
corporation (the "MSO") with reference to the following facts:

     WHEREAS,  pursuant to a Management  Services  Agreement (the  "Agreement"),
dated as of the date hereof,  between the New PC and the MSO, as  assurance  and
collateral  security for the payment of the monthly  Management Fees owed to the
MSO pursuant to the Agreement and any funds  advanced by the MSO to or on behalf
of the  New PC  pursuant  to the  Agreement  and  for the  faithful  and  timely
performance  of all the covenants  and  conditions to be performed by the New PC
under  the  Agreement  (collectively,  the  "Obligations")  the New PC agreed to
pledge,  grant,  bargain,  assign and  transfer to the MSO a security  interest,
pursuant to the Uniform  Commercial  Code of the State,  in and to all  Practice
Revenue and the accounts receivable of patients of the New PC, together with all
proceeds thereof (collectively, the "Collateral");

     WHEREAS,  the New PC is obligated  as a condition to the MSO's  performance
under the Agreement to execute and deliver this Security Agreement;

     NOW, THEREFORE,  in consideration of the foregoing and of the covenants and
agreements hereinafter set forth, the parties hereto agree as follows:

     1. Grant of Security Interest.  As and for collateral  security for payment
by the New PC of the  Obligations  and any and all  amounts  payable  under this
Security Agreement (collectively,  the "Secured Obligations"), the New PC hereby
pledges, grants,  bargains,  assigns and transfers to the MSO, and grants to the
MSO a security interest in, the Collateral.  Dr. Grove shall cause the New PC to
perform fully and on a timely basis all of the New PC's  obligations  under this
Security  Agreement.  The MSO may at its option file a financing statement (Form
UCC-1) in order to perfect its security interest hereunder.

     2.  Representations and Warranties.  The New PC represents and warrants all
of the accounts  receivable  constituting a portion of the Collateral of the New
PC pledged to the MSO are and will be validly created obligations of each of the
obligors who incurred same for services actually rendered in the ordinary course
of business of the New PC. Further,  the New PC represents and warrants that the
Collateral is not subject to any lien, pledge,  charge,  encumbrance or security
interest or right or option on the part of any third person.

     3. Release of Security Interest.  Upon the termination of the Agreement and
payment in full of the accrued  Management Fees thereunder and any and all other
Secured Obligations,  the MSO shall release its security interest hereunder, and
will deliver to the New PC any property forming part of the Collateral delivered
to the MSO and then held by the MSO hereunder.

     4.  Realization  of  Collateral.  The MSO shall have,  with  respect to the
Collateral,  the rights and




                                       35
<PAGE>

obligations of a secured party under the Uniform  Commercial  Code as adopted in
the  state  of  Nevada  (the  "State").  Such  rights  shall  include,   without
limitation, the following:

     A. The right,  upon default,  to have the Collateral,  or any part thereof,
transferred to its own name or to the name of its nominee;

     B. The  right,  upon  default,  to sell,  assign or  deliver as much of the
Collateral  as is  reasonably  necessary  to repay  the  defaulted  indebtedness
(together with expenses  attendant upon such sale and  repayment),  at public or
private  sale,  as the MSO may  elect,  either  for cash or on  credit,  without
assumption  of any  credit  risk and  without  demand or  advertisement  (unless
otherwise required by law).

     C.  The New PC  hereby  irrevocably  authorizes  the MSO to sign  and  file
financing  statements naming the New PC as the debtor and the MSO as the secured
party, at any time with respect to any Collateral,  without the signature of the
New  PC.  The  New PC  hereby  irrevocably  appoints  the  MSO as the  New  PC's
attorney-in-fact,  with full  authority in the place and stead of the New PC and
in the name of the New PC,  from time to time in the MSO's  discretion,  to take
any action and to execute any  instrument  which the MSO may deem  necessary  or
advisable to accomplish the purposes hereof. The attorney-in-fact granted herein
is coupled with an interest and is  irrevocable.  Third parties and entities and
persons  not a party to this  Security  Agreement  are  entitled to rely on this
attorney-in-fact  and an affidavit of the MSO attesting thereto.  The acceptance
of this  appointment  by the MSO shall not  obligate  it to perform  any duty or
covenant  required  to be  performed  by the New PC  under or by  virtue  of the
Collateral. Notwithstanding the foregoing power of attorney, the New PC shall at
any  time  on the  request  of the  MSO,  sign  Financing  Statements,  security
agreements or other agreements with respect to any Collateral. Upon the New PC's
failure  to  sign  said  Financing  Statements,  security  agreements  or  other
agreements,  the MSO is  authorized  as the agent of the New PC to sign any such
instruments.  Upon the  request of the MSO,  the New PC agrees to pay all filing
fees and to  reimburse  the MSO on demand for all costs and expenses of any kind
(including,  without  limitation,  legal fees) incurred in any way in connection
with the Collateral.

     5.  Purchase  of  Collateral.  At any such  private  or public  sale of the
Collateral  or  part  thereof,  the  MSO may  purchase  and pay for the  same by
cancellation of such portion of the Obligations, equal to the purchase price and
free of any  right  of  redemption  on the part of the New PC.  the MSO  agrees,
however,  that the New PC shall  have all  rights,  including  rights of notice,
provided by the  Uniform  Commercial  Code as adopted in the State.  In any case
where notice is required,  five days' notice shall be deemed reasonable  notice.
In the event of any sale  hereunder,  the MSO shall  apply the  proceeds  in the
order set forth  below in  Paragraph  6 hereof.  the MSO may have  resort to the
Collateral or any portion thereof with no requirements on the part of the MSO to
proceed first against any other person or property.

     6.  Application of Collateral.  Proceeds from the sale of the Collateral or
any part thereof shall be applied by the MSO in the following order:

     A. To the payment of the costs and expenses of  collection  incurred by the
MSO,  including,  without  limitation,  attorneys' fees and all other reasonable
expenses, liabilities and costs incurred by

                                       36

the MSO in connection therewith;

     B. To the payment of the whole  amount  then owing and unpaid for  advances
and/or Management Fees;

     C. To the payment in full of all other  Obligations of the New PC under the
Agreement; and

     D. To the payment to the New PC of any  surplus  then  remaining  from such
proceeds.

     7.  Extension of Agreement.  No renewal or extension of the  Agreement,  no
release  or  surrender  of  any  Collateral  given  as  security  in  connection
therewith,  and no delay in  enforcement  thereof or in exercising  any right or
power with respect  thereto or hereunder shall affect the rights of the MSO with
respect to the Collateral or any part thereof.

     8.  Notices.  Any notice to be given  pursuant to this  Agreement  shall be
deemed  effective  the same day when  such  notice  is given  personally,  or by
telegram,  or  electronic  transmission  to the  President  of the party to whom
notice is being given. Notice by mail shall be deemed effective three days after

                                   EXHIBIT E


                   ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A.Method of Invoking ADR Procedures

     1.  These  procedures  may be invoked  by any party to an  agreement  which
incorporates  these  procedures  by  giving  written  notice to the other of the
dispute  and   designating  a  person  with   decision-making   authority   (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required  to respond to the  disputing  party's  notice
within five (5) business days by designating in writing its own  representative.
A party may choose  more than one person to  represent  it. If a party  appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties,  each acting  through its  representative,  shall meet at a
mutually  acceptable  time  and  place  within  five  business  days  after  the
non-disputing party designates its representative to the other. At that meeting,
the  parties  shall  attempt  in good faith to  negotiate  a  resolution  of the
dispute,  or  failing  that,  to agree on a method  for  resolving  the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer  period of time as the parties may mutually  agree,  the parties have not
succeeded in  negotiating  a resolution of the claim or dispute or agreeing on a
dispute  resolution  mechanism,  they shall  submit the dispute to  mediation in
accordance with the procedures set forth herein.

     4. The  parties  will  jointly  appoint a mutually  acceptable  mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above,  then the parties  shall select a neutral third party from
the Center for Public Resources,  New York, New York ("CPR") Panels of Neutrals,
with the  assistance  of CPR,  unless the parties  agree  otherwise in finding a
mutually acceptable mediator.

     5. The New PC and the MSO shall  each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR.

     6. The parties  agree to  participate  in good faith in the  mediation  and
negotiations  related thereto for a period of thirty (30) days from  appointment
of a mediator by any of the parties or the CPR.


B.    Mediation procedures

     1. The mediator shall be neutral and impartial.


                                       39
<PAGE>

     2. The mediator shall control the procedural aspects of the mediation.  The
parties will cooperate fully with the mediator.


     (a) The  mediator  is free to meet and  communicate  separately  with  each
party.

     (b) The mediator  will decide when to hold joint  meetings with the parties
and when to hold separate meetings. There shall be no stenographic record of any
meeting. Formal rules of evidence will not apply.

     (c) The mediator may request that there be no direct communication  between
the parties or between their attorneys without the concurrence of the mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its  officers and an attorney.  Each party will have a  representative  fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator  will not transmit  information  received from any party to
another  party or any  third  person  unless  authorized  to do so by the  party
transmitting the information.

     6. The entire  process is  confidential.  The parties and the mediator will
not disclose information  regarding the process,  including settlement terms, to
third persons,  unless the parties otherwise agree. The process shall be treated
as a compromise  negotiation  for purposes of the Federal  Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing  administrative  and/or  judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

     (a)  The mediator will be disqualified  as a witness,  consultant or expert
          in any pending or future investigation,  action or proceeding relating
          to the subject matter of the mediation  (including any  investigation,
          action  or  proceeding  which  involves  persons  not  party  to  this
          mediation); and

     (b)  The mediator  and any  documents  and  information  in the  mediator's
          possession will not be subpoenaed in any such investigation, action or
          proceeding,  and all  parties  will  oppose  any  effort  to have  the
          mediator and documents subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the




                                       40
<PAGE>

parties and the mediator otherwise agree in writing.

     10. The mediator,  if a lawyer,  may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator  shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written  notice to the parties
(i) for overriding personal reasons,  (ii) if the mediator believes that a party
is not acting in good faith,  or (iii) if the  mediator  concludes  that further
mediation efforts would not be useful.

C.   Binding Arbitration

     If the  parties do not resolve the  dispute  through  mediation  within the
period provided in Part A above,  the parties shall submit the matter to binding
arbitration  in Boston,  Massachusetts  before a qualified  sole  arbitrator  in
accordance with the then current CPR Rules for  Non-Administered  Arbitration of
Business  Disputes.  The sole  arbitrator  shall be agreed  upon by the  parties
within  twenty  (20) days  after  either  party  elects  to submit  any issue to
arbitration or, failing that,  shall be selected by CPR. A qualified  arbitrator
is one who is familiar  with the  principal  subject  matter of the issues to be
arbitrated  such as by way of example,  healthcare  services  industry  matters,
management  consulting  services  generally  or business  law/corporate  matters
generally.  Judgment upon the award rendered by the arbitrator may be entered in
any court having  jurisdiction.  The arbitrator  shall not have the authority to

or engagement as independent contractors.

such  information  on an ongoing  basis in order to advise the New PC on ways of
improving operating efficiencies. The MSO shall provide training to the staff of
the New PC in the  implementation  and operation of such  standardized  business
systems and procedures.  The MSO shall additionally  provide the New PC with and
train the New PC's staff in the use of standardized  clinical forms,  including,

professional  service claims or matters not directly related to the operation of
the New PC or its  compliance  with  Laws,  or for any  legal or tax  advice  or
services or personal financial services to Dr. Churosh

and the Orthodontists (if any) or any employee or agent of the New PC.

     2.7 Billing,  Collection. The MSO shall be responsible for: (i) billing and

above shall be deposited  into an account (the "the New PC Account") with a bank

     employment of such personnel; and

          (2) All compensation payable to the MSO pursuant to Article 6 hereof.

     (c) In the  event  the  funds in the New PC  Account  will,  at any time be
insufficient  to cover  the  current  portion  of the  foregoing  expenses  when
payable,  the  MSO may  advance  to the New PC the  necessary  funds  to pay the
current  portion of such expenses for the benefit of the New PC, which  advances
will be deemed to be loans to the New PC to be repaid without  interest from the
New PC Account at such times as there are  adequate  funds  therein or upon such
other  terms and at such  times as  agreed  to by the New PC and the MSO,  which
indebtedness shall not be deemed an MSO Expense for purposes of Section 2.9.

licensure and  certifications of the Practice  Providers.  The MSO shall prepare
and file all  reports,  forms and  returns  required by Law in  connection  with
workers' compensation, unemployment insurance, social security and other similar
Laws with respect to the MSO's employees.

     2.18 Insurance. The MSO shall provide and pay for customary office property
damage and liability,  including business interruption insurance,  not including
professional  liability  insurance (which shall be and remain the responsibility
of the New PC).

     2.19  Practice  Transition  and Associate  Selection . Dr.  Churosh and the
Orthodontists  (if any) shall keep the MSO  informed of  retirement  goals on an
ongoing basis.  Upon request of the New PC, the MSO will conduct a search for an
appropriate  orthodontist  and  other  professionals  (collectively,   "Practice
Associates") for the purposes of accommodating practice growth,  reducing doctor
work schedule,  or planned retirement.  Such search shall include use by the MSO
of a national  journal  advertising  program and networking in the profession to
locate  appropriate  Practice  Associates.  The MSO estimates that it could take
approximately two years for such a search.

The  MSO  will  provide  screening  of all  applicants  and  will  then  present
appropriate  applicants  for final  selection by the New PC. The New PC shall be
responsible for interviewing and selecting each Practice Associate.

After the Practice  Associate(s)  is (are)  selected by the New PC, the MSO will
assist  the New PC with a trial  plan of  approximately  six  months for the new
Practice  Associate(s).  It is understood  that at the end of this period either
the New PC or the new Practice  Associate may terminate  the  relationship.  All
such Practice  Associates  recruited by the MSO as may be accepted by the New PC
shall be employees of the Practice (if so employed)  and not of the MSO. The MSO
will confer with the New PC on an appropriate salary/work-in arrangement for the
new Practice Associate and the final arrangements shall be determined by the New
PC.

                              DUTIES OF THE NEW PC


     3.1  General  The New PC shall be  responsible  for the  management  of its
practice and the Orthodontic  Office, in accordance with the requirements of the
Laws of the State.

     3.2 Employment of the  Orthodontists and Rendering of Patient Care. The New
PC shall be responsible for the employment and  professional  supervision of Dr.
Churosh  and  all  Orthodontists  and  the  other  Practice  Providers  and  all
orthodontic  care rendered to patients shall be rendered by Dr. Churosh and such
Orthodontists.   Additionally,   the  New  PC  shall  be  responsible   for  the
professional  supervision of all other Practice  Providers in their rendering of
patient care.

     3.3 Professional  Services. The New PC shall use and occupy the Orthodontic
Offices  designated  on  Schedule  2 hereof  exclusively  for the  practice  and
rendering of orthodontic services, and shall comply with all applicable Laws and
all standards of orthodontic  care. It is expressly  acknowledged by the parties
that the  orthodontic  practice  conducted at the  Orthodontic  Offices shall be
conducted  solely by Dr.  Churosh and the  Orthodontists  and the other Practice
Providers  acting  under the  supervision  and  control of Dr.  Churosh  and the
Orthodontists (if any), and no other  orthodontist  shall be permitted to use or
occupy the Orthodontic Offices.  The New PC shall provide professional  services
to patients hereunder in compliance at all times with ethical standards and Laws
applying to the orthodontic profession. The New PC shall ensure that Dr. Churosh
and each Orthodontist who provides  orthodontic services to patients is licensed
by the State. In the event that any disciplinary,  medical  malpractice or other
actions are initiated  against Dr. Churosh or any Orthodontist or other Practice
Provider,  the New PC shall  immediately  inform the MSO of such  action and the
underlying facts and circumstances subject to such confidentiality  agreement or
arrangements  as the New PC and the MSO shall mutually  determine at or prior to
the time of such disclosure. The New PC agrees to cooperate with and participate
in  quality  assurance/utilization  review  programs  established  by the MSO or
mandated by accreditation and licensure standards  applicable to the practice of
orthodontics.  Deficiencies discovered in the performance of any personnel or in
the quality of professional  services shall be reported  immediately to the MSO,
and  appropriate  steps  shall  be taken  by the New PC at once to  remedy  such
deficiencies.

     3.4 Records.  The New PC will keep or cause to be kept  accurate,  complete
and timely  dental and other  records of all  patients.  The  management  of all
dental and patient  files and records  shall  comply  with all  applicable  Laws
regarding their confidentiality and retention and all files and records shall be
located so that they are readily  accessible for patient care,  consistent  with
ordinary  records  management  practices.  Such


                                       8
<PAGE>


records  shall be  sufficient  to  enable  the MSO,  on behalf of the New PC, to
obtain  payments for services and related charges and to facilitate the delivery
of quality patient care by the New PC.  Notwithstanding  the foregoing,  patient
dental  records  shall be and remain the property of the New PC and the contents
thereof shall be solely the responsibility of the New PC.

     3.5 Professional  Expenses.  The New PC shall be solely responsible for the
cost of professional  licensure fees and board certification fees, membership in
professional associations and continuing professional education incurred by each
Orthodontist  and other  Practice  Provider  employed  by the New PC. The New PC
shall ensure that Dr. Churosh and all the  Orthodontists  employed by the New PC
participate  in such  continuing  education as is necessary for Dr.  Churosh and
such the Orthodontists to remain current.

     3.6 Professional Liability Insurance.  The New PC shall provide, or arrange
for the  provision  of,  and  maintain  throughout  the Term of this  Agreement,
professional  liability  insurance coverage in accordance with the provisions of
Article 9 hereof. The New PC shall also cooperate in any programs recommended by
the MSO to assure  that each of its  Orthodontists  is  insurable,  and that Dr.
Churosh  and each  Orthodontist  participates  in an  on-going  risk  management
program.

     3.7  Employment  Agreement.  The parties  recognize that the services to be
provided  by the  MSO  are  feasible  only  if the  New PC  operates  an  active
orthodontic  practice to which it, Dr. Churosh and each Orthodontist  associated
with the New PC devote  their full time and  attention,  unless  other  specific
provisions  are made in writing and mutually  agreed upon by the MSO and New PC.
The New PC will cause Dr. Churosh and each individual Orthodontist who now is or
hereafter becomes  affiliated with the New PC to enter into a written employment
agreement (the "Employment Agreement") satisfactory in form and substance to the
MSO,  pursuant  to which Dr.  Churosh  or the  Orthodontist  shall  agree not to
establish,  operate or provide orthodontic or dental services, without the prior
written  consent of both the New PC and the MSO, at any office or facility other
than the  Orthodontic  Office.  In addition,  such  Employment  Agreement  shall
provide by its own terms or by a separate  agreement  that if Dr.  Churosh's  or
such Orthodontist's employment shall terminate for any reason during the Term of
this Agreement, for a period of 24 months after the termination of Dr. Churosh's
or such Orthodontist's Employment Agreement with the New PC, Dr. Churosh or such
Orthodontist  shall agree not to establish,  operate or provide  orthodontic  or
dental  services,  without the prior written  consent of both the New PC and the
MSO, at any office practice or facility whatsoever providing services similar to
those  provided by the New PC at any  orthodontic  office  within a fifteen (15)
mile  radius.  Such  Employment  Agreement  (or separate  agreement)  shall also
provide,  among other things,  that in the event of a breach of Dr. Churosh's or
the Orthodontist's agreement not to compete with the New PC provided for in such
Employment  Agreement  (or  separate  agreement),  the MSO shall be  entitled to
receive,  in  addition  to  other  remedies  and  not by way of an  election  of
remedies,  liquidated damages equaling the greater of: (a) Dr. Churosh's or such
Orthodontist's  income, as shown on the W-2 form prepared by the New PC, for the
most recent  calendar  year; or (b) $300,000.  Such payment shall be made to the
MSO by the New PC immediately  following receipt of the payment from Dr. Churosh
or the breaching  Orthodontist by the New PC. Each of the MSO and OMEGA shall be
expressly named as a third-party  beneficiary to such agreements between the New
PC and Dr. Churosh and each  Orthodontist and the rights and remedies of the MSO
and OMEGA  thereunder or otherwise in respect of the  restrictive  covenants set
forth in such agreements shall survive termination of this Agreement.

     3.8 Confidentiality.  The New PC agrees and acknowledges that all materials
provided by the MSO to the New PC constitute "Confidential  Information" and are
disclosed in confidence and with the understanding that it constitutes  valuable
business information  developed by the MSO with the assistance of OMEGA at great
expenditures of time,  effort and money. The New PC further agrees that it shall
not,  directly or indirectly,  without the express prior written  consent of the
MSO, use or disclose such Confidential Information for any purpose other than in
connection  with the  services  to be  rendered  hereunder.  The New PC  further
agrees:  (i) to keep strictly  confidential  and hold in trust all  Confidential
Information and not disclose such  Confidential  Information to any third party,
including its shareholders, directors, officers, affiliates, partners, employees
and  independent  contractors  without the express prior written  consent of the
MSO; and (ii) to impose this obligation of  confidentiality on its shareholders,
directors,   officers,   affiliates,   partners,   employees   and   independent
contractors.  The  New PC  acknowledges  that  the  disclosure  of  Confidential
Information  to it by the MSO is done in reliance upon its  representations  and
covenants in this Agreement. Upon expiration or termination of this Agreement by
either party for any reason whatsoever,  the New PC shall immediately return and
shall  cause  its  shareholders,   directors,  officers,  affiliates,  partners,
shareholders  and independent  contractors to immediately  return to the MSO all
Confidential  Information,  and  the  New  PC  will  not,  and  will  cause  its
affiliates,  partners,  employees and independent contractors not to, thereafter
use, appropriate, or reproduce such Confidential Information. The New PC further
expressly   acknowledges  and  agrees  that  any  such  use,   appropriation  or
reproduction of any such Confidential  Information by any of the foregoing after
the  expiration or  termination  of this  Agreement  will result in  irreparable
injury to the MSO and OMEGA,  that the remedy at law for the foregoing  would be
inadequate,  and  that  in  the  event  of  any  such  use,  appropriation,   or
reproduction  of any such  Confidential  Information  after the  termination  or
expiration  of this  Agreement,  the MSO and  OMEGA,  in  addition  to any other
remedies or damages  available  to either or both of them,  shall be entitled to
injunctive or other  equitable  relief  without the necessity of proving  actual
damages  but such  rights to relief  shall not  preclude  the MSO and OMEGA from
other remedies which may be available to either or both of them hereunder.

                 PROFESSIONAL SERVICES, CONTROL OF SOLICITATION,
              APPROVAL OF ADVERTISING MATERIAL AND NO RECIPROCATION


     4.1 A  fundamental  understanding  between the  parties  hereto is that the
rendering of  orthodontic  services shall be separate and  independent  from the
provision of  administrative,  management and support services by the MSO. Thus,
the  New PC  shall  have  sole  and  absolute  control  of the  delivery  of all
professional  services  and  treatment  rendered to patients at the  Orthodontic
Offices.

     4.2 No employee or other  representative of the MSO shall be engaged in, or
allowed to solicit patients on behalf of, the New PC, nor shall the MSO have any
control over the New PC's patients.

     4.3 No  advertising  or promotional  materials,  or other  materials of any
nature,   including   billing  and  collection   forms,   reports,   agreements,
correspondence,  or similar materials,  used in connection with the New PC shall
be used or distributed without having first been approved by the New PC.

     4.4 The parties hereby  acknowledge  and agree that the benefits  conferred
upon each of them hereunder  neither  require nor are in any way contingent upon
the  admission,  recommendation,  referral,  or any  other  arrangement  for the
provision  of any item or service  offered by the MSO to any patients of the New
PC or its shareholders,  officers, directors, employees,  contractors or agents,
nor are such benefits in any way contingent upon the recommendation, referral or
any other  arrangement  for the provision of any item or service  offered by the
New PC or any of its Practice Providers, employees, contractors or agents.

     5.1 In  consideration  of the sums to be paid to the MSO under the terms of
this Agreement, the MSO hereby leases or sub-leases,  as applicable,  to the New
PC during the Term of this Agreement the Orthodontic  Offices, and the leasehold
improvements and fixtures, furniture and equipment at the Orthodontic Offices as
listed from time to time on Schedule 2 attached hereto and  incorporated  herein
by this reference, under the following terms and conditions:

     (a) The MSO is the  lessee  by  assignment  under  lease  for the  premises
occupied by the New PC  (collectively,  the  "Master  Lease") a copy of which is
attached hereto as Exhibit A and incorporated herein by this reference.  The New
PC hereby  acknowledges  that the premises  described under the Master Lease are
suitable for the New PC's  orthodontic  practice.  Based and contingent upon the
New PC's  promise to timely pay all  amounts due under this  Agreement,  the MSO
hereby  agrees to sublease the leased  premises to the New PC upon the following
terms and conditions:

          (i) This sublease between the MSO and the New PC of the premises shall
     be subject to all of the terms and  conditions of the Master Lease.  In the
     event of the  termination  of the MSO's interest as lessee under the Master
     Lease for any reason, then the sublease created hereby shall simultaneously
     terminate, unless the New PC assumes the obligations under the Master Lease
     in question and the Lessor consents thereto.

          (ii) All of the terms and conditions contained in the Master Lease are
     incorporated  herein as terms and  conditions  of the  sublease  (with each
     reference  therein to "Lessor"  and  "Lessee," to be deemed to refer to the
     MSO and the New PC,  respectively)  and,  along with the provisions of this
     Section  5.1(b) and Exhibit "A," shall be the complete terms and conditions
     of the sublease created hereby.

          (iii)  Notwithstanding  the foregoing,  as between the MSO and the New
     PC,  the MSO shall  remain  responsible  for  meeting  the  obligations  of
     "Lessee" under the sections  entitled  Rent,  Additional  Rent  Adjustment,
     Insurance  on  Fixtures,  Liability  Insurance,  Repairs,  and Taxes of the
     Master Lease,  all of which  obligations  shall be considered  MSO Expenses
     hereunder and the New PC shall have no monetary  obligation in that regard.
     In  addition,  as between the MSO and the New PC, the MSO shall  retain the
     right to exercise any options to purchase the  premises,  or other  similar
     rights of ownership or  possession,  which may be granted  under the Master
     Lease, and the New PC shall have no rights in that regard.

<PAGE>


          (iv) In the event this Agreement is terminated according to its terms,
     this sublease shall also terminate automatically.

          (v) If the Master Lease contains an option to renew the terms thereof,
     the MSO shall  notify the New PC, at least 30 days prior to the  expiration
     of the time for exercising such option,  of the MSO's intention to renew or
     not to renew such term. If the MSO  determines  not to renew such term, the
     MSO shall provide or arrange for the  provision of comparable  office space
     (the  "Substitute  Orthodontic  Office") within a radius of 15 miles of the
     Orthodontic Office, which Substitute Orthodontic Office shall be subject to
     the  approval  of the New PC  (which  approval  shall  not be  unreasonably
     withheld or delayed). The lease or sublease for such Substitute Orthodontic
     Office,  as  applicable,  shall be substituted  for the lease  described on
     Exhibit A hereto and all references to the "Master Lease" shall  thereafter
     be  applicable  to the lease or  sublease  for the  Substitute  Orthodontic
     Office for purposes of this Agreement, ab initio.

          (vi)  The  Alternative  Dispute  Resolution  provisions  set  forth in
     Article 14 of this Agreement  shall not apply to any issues  concerning the
     Sub-Lease,  the New PC's  tenancy  or the  MSO's  rights  and  remedies  as
     Sub-Lessor.

     5.2 The  MSO  shall  provide  the New PC at the  Orthodontic  Offices  such
additional  leasehold  improvements,   fixtures,   furniture,   furnishings  and
equipment as may be mutually  agreed to with the New PC and reflected  from time
to time on a  supplement  to  Schedule  2  hereto.  The use by the New PC of all
leasehold improvements,  fixtures, furniture, furnishings and equipment provided
hereunder shall be subject to the following conditions:

     (a)  Title  to all  such  leasehold  improvements,  fixtures,  furnishings,
furniture and  equipment  shall remain in the MSO and upon  termination  of this
Agreement,  the New PC shall immediately return and surrender all such leasehold
improvements,  fixtures,  furniture,  furnishings and equipment to the MSO in as
good condition as when received, normal wear and tear excepted.

     (b) The MSO shall be fully and  entirely  responsible  for all  repairs and
maintenance of all such leasehold improvements, fixtures, furniture, furnishings
and equipment;  provided,  however,  that the New PC agrees that it will use its
best  efforts to prevent  damage,  excessive  wear,  and  breakdown  of all such
leasehold  improvements,  fixtures,  furniture,  furnishings and equipment,  and
shall advise the MSO of any and all needed repairs and equipment failures.

     (c)  The  obligation  of the MSO to  provide  the  leasehold  improvements,
fixtures, furniture, furnishings and equipment stated herein shall be concurrent
and co-extensive with the Term of this Agreement.

     5.3. No Warranty.

     (a)  THE  NEW  PC  ACKNOWLEDGES   THAT  THE  MSO  MAKES  NO  WARRANTIES


                                       12

OR REPRESENTATIONS, EXPRESS OR IMPLIED, AS TO THE SUITABILITY OR ADEQUACY OF ANY
LEASEHOLD IMPROVEMENTS,  FIXTURES, FURNITURE, FURNISHINGS,  EQUIPMENT, INVENTORY
OR SUPPLIES  PROVIDED OR LEASED OR SUBLEASED  PURSUANT TO THIS AGREEMENT FOR THE
CONDUCT OF AN ORTHODONTICS PRACTICE OR FOR ANY OTHER PARTICULAR PURPOSE.

     (b) Nothing in this Agreement  shall be construed to affect or limit in any
way the  professional  discretion  of the  Practice  Providers to select and use
fixtures, furniture, furnishings and equipment, inventory and supplies purchased
or provided  by the MSO in  accordance  with the  provisions  of this  Agreement
insofar as such selection or use constitutes or might constitute the practice of
dentistry or orthodontics.

                                    ARTICLE 6
                                  COMPENSATION


     As  consideration  for the performance of all of its duties and obligations
as  provided  in this  Agreement,  including  but not  limited to, the costs and
expenses  associated  with  furnishing  the  services,  personnel,   facilities,
leasehold improvements, fixtures, furniture, furnishings, equipment, inventories
and supplies provided for herein, the MSO shall receive compensation in the form
of monthly  management fees (the  "Management  Fees") based upon a predetermined
percentage of the "Practice  Revenues",  as defined and determined in accordance
with the  provisions  set forth in Schedule 3 attached  hereto and  incorporated
herein by this reference,  as such Schedule may be amended by the New PC and the
MSO from time to time. It is acknowledged by and between the parties hereto that
the MSO and/or its  affiliates  has (have)  incurred  substantial  expenses  and
future  obligations  in  acquiring  the capital  stock of the MSO,  acquiring or
otherwise  establishing  the  Orthodontic  Offices,  establishing  its  systems,
including fees for consultants and other professionals,  interest expense, lease
obligations,  and costs of furnishing or refurbishing  the premises at which the
Orthodontic   Offices  are  located.   The  MSO  has  also  assumed  substantial
obligations associated with the continuing operation of the Orthodontic Offices,
including  those of  lessee,  obligor  and  guarantor  and  obligor  on loans to
establish and operate the Orthodontic  Offices. The parties,  therefore,  having
considered various  compensation  formulae,  acknowledge and agree that in order
for the MSO to  receive  a fair  and  reasonable  return  for its  expenses  and
obligations,  and a fair return for the lease of the premises and  equipment and
for providing the services contemplated hereunder,  that the agreed compensation
is not excessive.  The New PC acknowledges that the compensation  arrangement is
reasonable  under the  circumstances  noted herein and has executed an Affidavit
attesting  to this fact  which is  attached  hereto and  incorporated  herein as
Exhibit C. In consideration of the foregoing, the parties agree that the monthly
Management Fees payable to the MSO by the New PC for services  rendered pursuant
to this  Agreement  shall be reviewed and subject to  adjustment at the close of
each  year of the  Term of this  Agreement  based  upon  industry  standards  of
practice and the MSO's costs in performing the required services. If the parties
cannot agree within  thirty (30) days prior to the close of any such year on the
terms of any adjustment to the Management  Fees for the following year, then the
then existing  Management  Fees shall remain in effect.  The New PC specifically
agrees  that the MSO may defer  actual  receipt of its  Management  Fees  and/or
advance  monies for purposes of managing the New PC's cash flow, and the MSO may
repay itself such  advances or pay said deferred  Management  Fees when it deems
appropriate.

                                SECURITY INTEREST


     As  assurance  and  collateral  security  for the  payment  of the  monthly
Management  Fees  owed  to the MSO  pursuant  to this  Agreement  and any  funds
advanced by the MSO to or on behalf of the New PC pursuant to this Agreement and
for the faithful and timely  performance  of all the covenants and conditions to
be  performed  by the New PC under this  Agreement,  the New PC hereby  pledges,
grants, bargains, assigns and transfers to the MSO a security interest, pursuant
to the Uniform  Commercial Code of the State, in and to all Practice Revenue and
accounts  receivable  of  patients  of the New PC,  together  with all  proceeds
thereof  (collectively,  the  "Collateral"),  and further  agrees not to pledge,
assign,  transfer or convey any of the  Collateral  or any  proceeds  therefrom,
without the prior written  consent of the MSO,  except to affiliates of the MSO.
Concurrent  with the  execution of this  Agreement,  the New PC shall  execute a
Security  Agreement,  similar  in form and  content as that  attached  hereto as
Exhibit D and  incorporated  herein by this  reference in order that the MSO may
perfect its interest in the Collateral.  The New PC expressly  agrees to execute
any  appropriate  UCC-1  Financing  Statement and UCC-1 Fixture  filings,  if so
requested in writing by the MSO.

                                    COVENANTS


     8.1 New PC's Covenants.  As further consideration for the MSO's performance

practice at the Orthodontic  Offices, or any other orthodontic  practice managed
by the MSO,  within a radius  of 15 miles of the  Orthodontic  Office or of such
other orthodontic practice, without the MSO's prior written consent.

     (d) The New PC recognizes the  proprietary  interest of OMEGA in and to its
OMEGA  Patient  Scheduling  System and the MSO in its systems for  managing  the
delivery of orthodontic care and all policies,  procedures,  operating  manuals,

Information") regarding such system. The New PC acknowledges and agrees that all
information  relating  to the  OMEGA  Patient  Scheduling  System  and  the  MSO
Information constitutes trade secrets of OMEGA and/or the MSO. The New PC hereby
waives any and all right,  title and  interest in and to such trade  secrets and
agrees to return all  copies of such  trade  secrets  and  information  relating
thereto, at its expense, upon termination of this Agreement.

     (e) The New PC acknowledges  and agrees that OMEGA and the MSO are entitled
to prevent their  respective  competitors  from  obtaining  and utilizing  their
respective trade secrets.  The New PC agrees to hold OMEGA'S and the MSO's trade

disclosed  directly or indirectly to any person or entity other than persons who
are engaged by the New PC to perform  duties in  connection  with the New PC and
who have a need to know such trade  secrets in the  performance  of their duties
for the New PC, without OMEGA's or the MSO's prior written consent,  as the case
may be. The New PC acknowledges  its fiduciary  obligations to OMEGA and the MSO
and the  confidentiality  of its relationships with OMEGA and the MSO and of any
information  relating to the services and business  methods of OMEGA and the MSO
which it may  obtain  during the term of this  Agreement.  The New PC shall not,
either during the term of this  Agreement or at any time after the expiration or
sooner  termination  hereof,   disclose  to  anyone,  other  than  employees  or
independent  contractors  of OMEGA  and the MSO who use  OMEGA's  and the  MSO's
system in the course of the  performance of their duties,  any  confidential  or
proprietary information or trade secrets obtained by the New PC. The New PC also
agrees to place  any  persons  to whom said  information  is  disclosed  for the
purpose of  performance  under legal  obligation  to treat such  information  as
strictly confidential.

     8.2 MSO's Covenants.  As further consideration for the New PC's performance
of the terms and conditions of this Agreement, the MSO covenants, represents and
warrants  (which  covenants,  representations  and warranties  shall survive the
execution of this  Agreement)  that during the Term of this  Agreement,  the MSO
agrees not to  establish,  develop or open any  offices in  affiliation  with an
orthodontist  for the provision of orthodontic  services within a 15 mile radius
of the Orthodontic Offices, without the express written consent of the New PC.

                             INSURANCE AND INDEMNITY

     9.1 Insurance to be Maintained by the New PC.  Throughout  the Term of this
Agreement,  the New PC shall  maintain  in full force and  effect  comprehensive
professional  liability  insurance  with  limits of not less than  $500,000  per
occurrence  and  $1,000,000  annual  aggregate  per Dr.  Churosh and each of the
Orthodontists providing services for the New PC and a separate limit for the New
PC. The New PC shall be responsible for all liabilities  within  deductibles and
for all liabilities in excess of the limits of such policies.  The MSO agrees to
negotiate for and cause premiums to be paid on behalf of the New PC with respect
to such insurance.  Premiums and deductibles with respect to such policies shall
not be MSO  Expenses.  The  New PC also  agrees  to name  the MSO and  OMEGA  as
co-insureds.  The New PC agrees to deliver to the MSO and OMEGA a certificate of
insurance indicating such coverage.

     9.2  Insurance to be  Maintained  by the MSO.  Throughout  the Term of this
Agreement, the MSO will use reasonable efforts to provide and maintain, as a MSO

liability  insurance  for all  professional  employees of the MSO with limits as
determined  reasonable by the MSO; and (b)  comprehensive  general liability and
property insurance covering the Orthodontic Office premises and operations.

     9.3 Tail  Insurance  Coverage.  The New PC will cause Dr.  Churosh and each
Orthodontist (if any) providing services to enter into an agreement with the New
PC that upon  termination of Dr. Churosh's or such  Orthodontist's  relationship
with the New PC, for any reason,  tail  insurance  coverage will be purchased by
Dr.  Churosh  or such  Orthodontist.  Such  provisions  may be  contained  in an
employment agreement,  restrictive covenant agreement or other agreement entered
into by the New PC and Dr.  Churosh or the  Orthodontist,  and the New PC hereby
covenants with the MSO to enforce such provisions relating to the tail insurance
coverage or to provide such coverage at the expense of the New PC or Dr. Churosh
or each such Orthodontist.

     9.4  Additional  Insureds.  The  New PC and  the  MSO  agree  to use  their
reasonable  efforts to have each  other  named as an  additional  insured on the
other's respective liability insurance policies.

     9.5 Indemnification.  The New PC shall indemnify,  hold harmless and defend
the MSO and  OMEGA  and  their  respective  officers,  directors,  shareholders,
employees and representatives,  from and against any and all liability,  losses,
damages, claims, causes of action, expenses judgments, settlements, lawsuits and
obligations  (including  reasonable  attorneys' fees), whether or not covered by
insurance, caused or asserted to have been caused, directly or indirectly, by or
as a result of the performance of orthodontic services or the performance of any
intentional  acts,  negligent  acts  or  omissions  by  the  New PC  and/or  its
affiliates,  its  shareholders,   agents,  the  Practice  Providers,  its  other
employees and/or its subcontractors (other than the MSO) during the Term hereof.
The MSO shall  indemnify,  hold  harmless  and defend the New PC, its  officers,

attorneys'  fees),  caused  or  asserted  to  have  been  caused,   directly  or
indirectly,  by or as a  result  of the  performance  of any  intentional  acts,
negligent  acts  or  omissions  by the  MSO  and/or  its  shareholders,  agents,
employees and/or subcontractors (other than the New PC) during the Term hereof.

                     AUTHORIZED AGENT AND POWERS OF ATTORNEY

     The New PC hereby  designates  the MSO (and its  designees)  its authorized
agent and lawful  attorney-in-fact for purposes of depositing  payments,  paying
accounts  payables,  signing  checks,  negotiating  and  signing  contracts  for
services or goods,  securing loans or incurring obligations on behalf of the New
PC; provided,  however, that all contracts or fees set for services on behalf of
the New PC will be  subject  to final  approval  and  acceptance  by the New PC.
Additionally, the New PC hereby irrevocably appoints the MSO (and its designees)
its  authorized  agent and  lawful  attorney-in-fact  to  collect  all bills and
accounts  receivable  for  professional  fees,  charges  and other  amounts  and
authorizes the MSO through its designees to take possession of all checks, money
orders  and  similar  instruments  received  as  payment  of  receivables  to be
deposited into the New PC Account.  The New PC hereby  irrevocably  appoints the
MSO as the New PC's attorney-in-fact, with full power and authority in the place
and stead of the New PC, in the MSO's discretion,  to endorse in the name of the
New PC any checks,  payments,  notes,  insurance  payments and money orders,  to
withdraw  funds for payments of expenses,  including  Management  Fees and other
sums  payable to the MSO,  to open and close the New PC  Account  and other bank
accounts,  to take any action and to execute any other  instrument which the MSO
may deem necessary or advisable to accomplish the purposes hereof. The powers of
attorney granted herein are coupled with an interest and are irrevocable.  Third
parties and entities and persons not a party to this  Agreement  are entitled to
rely on the  foregoing  attorneys-in-fact  and an affidavit of the MSO attesting
thereto.  The acceptance of this appointment by the MSO shall not obligate it to
perform any duty or covenant  required to be performed by the New PC under or by
virtue of this Agreement.  Notwithstanding the foregoing powers of attorney, the
New PC shall at any time, on the request of the MSO, sign financing  statements,
security agreements or other agreements necessary or advisable to accomplish the
purpose of this  Agreement.  Upon the New PC's  failure  to sign said  financing
statements,  security  agreements or other agreements,  the MSO is authorized as
the agent of the New PC to sign any such instruments.  The New PC may review all
deposits and expenses upon request.

                                   ARTICLE 12
                       INDEPENDENT CONTRACTOR RELATIONSHIP


     Neither  the New PC nor its  employees  shall  have any  claim  under  this
Agreement or otherwise against the MSO for worker's  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 the New PC. Since  neither the New PC nor its  employees  are
employees  of the MSO,  the MSO  shall  not  withhold  on  behalf  of the New PC
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 the New PC.

                                   ARTICLE 13
                                  MISCELLANEOUS

     13.1 Access to Records.  From and after any  termination,  each party shall
provide the


                                       18
<PAGE>


other  party with  reasonable  access to books and  records  then owned by it to
permit such requesting  party to satisfy  reporting and contractual  obligations
which may be required of it.

     13.2 Patient Records. Upon termination of this Agreement,  the New PC shall
retain all patient  dental  records  maintained  by the New PC or the MSO in the
name of the New PC. During the term of this Agreement,  and thereafter,  the New
PC or its designee shall have reasonable  access during normal business hours to
the New PC's and the MSO's  records,  including,  but not limited to, records of
collections,  expenses and  disbursements  as kept by the MSO in performing  the
MSO's obligations under this Agreement,  and the New PC may copy any or all such
records.

     13.3 The New PC's Control Over the  Orthodontic  Practice.  Notwithstanding
the authority  granted to the MSO herein,  the MSO and the New PC agree that the
New PC,  personally or through Dr. Churosh or any of its  Orthodontists (if any)
and other Practice  Providers,  shall have complete control and supervision over
the professional  aspects of the New PC's practice,  as well as the provision of
all professional  services,  including,  without limitation,  the selection of a
course of treatment for a patient,  the  procedures or materials to be used as a
part of such  course  of  treatment,  and the  manner  in which  such  course of
treatment is carried out by the New PC. The New PC shall have sole  authority to
direct the business,  professional,  and ethical  aspects of the New PC. The MSO
shall have no  authority,  directly or  indirectly,  to  perform,  and shall not
perform, any orthodontic  function,  or to influence or otherwise interfere with
the exercise of the New PC's professional judgment. The MSO may, however, advise
the  New  PC as to the  relationship  between  its  performance  of  orthodontic
functions and the overall administrative and business functioning of the New PC.

                         ALTERNATIVE DISPUTE RESOLUTION

     14.1 Alternative Dispute Resolution.

     (a) If a dispute  arises  under this  Agreement  which  cannot be  resolved
informally  by the  parties,  any party may invoke the  procedures  set forth in
Exhibit E hereto and the parties agree to use these procedures, except paragraph
(b) of this Section 14.1, prior to any party pursuing other available  remedies.
The parties  will meet and attempt in good faith to resolve any  controversy  or
claim arising out of or relating to this Agreement.

     (b) Notwithstanding anything in this Section 14.1 to the contrary:

          (i) Nothing in this Section 14.1 shall preclude any party from seeking
     a preliminary  injunction or other provisional  relief,  either prior to or
     during the proceeding provided for in this section, if in its judgment such
     action is necessary to avoid  irreparable  damage or to preserve the status
     quo.

          (ii)  The  parties  shall  accept  as  correct,   final,  binding  and
     conclusive the  determination  by the outside  accountants then employed by
     the MSO as to the  calculation of any and all  Management  Fees owed by the
     New PC to the MSO hereunder, and such determination shall not be subject to
     the   provisions  of  this  Section   14.1.   Disputes  as  to  the  proper
     interpretation of the provisions of this Agreement which


                                       19
<PAGE>


     describe how those amounts are to be calculated,  however, shall be subject
     to the provisions of this Section 14.1.

          (iii) Any determination by either party not to renew this Agreement in
     accordance  with the terms and  provisions of this  Agreement  shall not be
     subject to the provisions for dispute resolution in this Section 14.1.

     14.2  Waiver of Jury.  With  respect  to any  dispute  arising  under or in
connection  with this  Agreement  or any  related  agreement,  as to which legal
action  nevertheless  occurs, each party hereby irrevocably waives all rights it
may have to demand a jury trial.  This waiver is  knowingly,  intentionally  and
voluntarily  made by the  parties  and each  party  acknowledges  that no person
acting  on behalf of the  other  party  has made any  representation  of fact to
induce this  waiver of trial by jury or in any way  modified  or  nullified  its
effect.  The parties each further  acknowledge  that it has been represented (or
has had the  opportunity to be represented) in the signing of this Agreement and
in the making of this waiver by independent  legal counsel,  selected of its own
free will,  and that it has had the  opportunity  to discuss  this  waiver  with
counsel.  Each party further  acknowledges  that it has read and understands the
meaning and ramifications of this waiver provision.

                                   ARTICLE 15
                               GENERAL PROVISIONS

     15.1 Notices.  Any notice to be given pursuant to this  Agreement  shall be
deemed  effective if given  personally,  or by  telephone,  telegram,  telecopy,
facsimile  or other  electronic  transmission,  or by  letter to an  officer  or
administrator  of OMEGA,  the MSO or the New PC,  as the case may be.  Notice in
person,  or by telephone,  telegram or electronic  transmission  shall be deemed

hours after  deposit in the United  States mails,  and properly  addressed  with
postage prepaid.

     Notices to the New PC shall be given as follows:

time in writing.

<PAGE>


or other such  addresses  as may be furnished by the MSO to the New PC from time
to time in writing.

     15.2  Confidentiality.  No party hereto shall disseminate or release to any
third party any information  regarding any provision of this  Agreement,  or any
financial information regarding the other parties (past, present or future) that
was obtained in the course of the negotiation of this Agreement or in the course
of the performance of this Agreement,  without the other party's or parties' (as
the case may be) written approval;  provided,  however,  the foregoing shall not
apply to information which is required to be disclosed by Law, including federal
or state securities laws, or pursuant to court order.

     15.3 Contract  Modifications for Prospective Legal Events. In the event any
state or  federal  Laws,  now  existing  or  enacted  or  promulgated  after the
effective  date of this  Agreement,  are  interpreted  by judicial  decision,  a
regulatory  agency  or legal  counsel  for both  parties  in such a manner as to
indicate that the structure of this  Agreement may be in violation of such Laws,
the New PC and the MSO shall amend this  Agreement as necessary.  To the maximum
extent possible,  any such amendment shall preserve the underlying  economic and
financial arrangements between the New PC and the MSO.

     15.4  Remedies  Cumulative.  No  remedy  set  forth  in this  Agreement  or
otherwise conferred upon or reserved to any party shall be considered  exclusive
of any other  remedy  available  to any party,  but the same shall be  distinct,
separate  and  cumulative  and may be  exercised  from  time to time as often as
occasion may arise or as may be deemed expedient.

     15.5 No Obligation to Third Parties.  None of the obligations and duties of
the MSO or the New PC under this Agreement  shall in any way or in any manner be
deemed to create  any  obligation  of the MSO or of the New PC to, or any rights
in, any person or entity not a party to this  Agreement  other than OMEGA  which
shall be deemed a party for limited purposes as set forth in this Agreement.

     15.6 Entire Agreement.  This Agreement including the Schedules and Exhibits
hereto,  together  with the Stock  Put/Call  Option  and  Successor  Designation
Agreement of even date herewith and the Employment  Agreement(s)  (including the
related  non-competition  agreements  or  covenants),   constitutes  the  entire
agreement between the parties concerning this subject matter, and supersedes all
prior and contemporaneous agreements,  representations and understandings of the
parties  concerning  the  contents  hereof.  No  supplement,   modification,  or
amendment to this Agreement  shall be binding unless  executed in writing by all
of the parties hereto,  except as otherwise provided herein. No waiver of any of
the provisions of this  Agreement  shall be deemed to constitute a waiver of any
other provision, whether similar or not similar, nor shall any waiver constitute
a continuing  waiver.  No waiver shall be binding unless  executed in writing by
the party making the waiver.

     15.7  Assignment.  The  rights  and the  duties of the  parties  under this
Agreement may not be assigned or transferred  without the prior written  consent
of the non-assigning  party,  which consent shall not be unreasonably  withheld;
provided,  however,  that the MSO shall be  permitted  to assign  its rights and
obligations  hereunder without the consent of the New PC to any person,  firm or
corporation  controlled by the MSO,  controlling the MSO or under common control
with the MSO.

     15.8 Attorneys' Fees. If any mediation or arbitration or other legal action
or  proceeding  is brought to enforce  this  Agreement,  because of any  alleged
breach hereof, or for a declaration of any rights and obligations hereunder, the
prevailing party in such mediation or arbitration, action or proceeding shall be
entitled to recover its costs incurred therein,  including reasonable attorneys'
fees,  in  addition  to any  other  relief to which it may be  entitled,  all as
determined  and awarded by the parties in such mediation or by the arbitrator or
court as part of its judgment or decision therein, as the case may be.

     15.9 Governing  Law. This  Agreement  shall be governed by and construed in
accordance with the laws of the State.  The parties  acknowledge that the MSO is
not  authorized or qualified to engage in any activity which may be construed or
deemed to constitute  the practice of dentistry or  orthodontics.  To the extent
any act or service  required of the MSO in this Agreement should be construed or
deemed,  by any  governmental  authority,  agency  or  court to  constitute  the
practice of dentistry or orthodontics, the performance of said act or service by
the MSO shall be deemed waived and forever  unenforceable  and the provisions of
Section 15.14 shall be applicable.

     15.10 Events  Excusing  Performance.  Neither  party shall be liable to the
other party for failure to perform any of the  services  required  herein in the
event of strikes, lock-outs, calamities, acts of God, unavailability of supplies
or other  events over which that party has no control for so long as such events
continue, and for a reasonable period of time thereafter.

     15.11  Compliance with Applicable  Laws. Both parties shall comply with all
applicable  Laws and  restrictions  imposed  thereunder  in the conduct of their
obligations under this Agreement.

     15.12 Language  Construction.  The parties  acknowledge that each party and
its counsel have reviewed and revised this Agreement and that the normal rule of
construction to the effect that any  ambiguities are to be resolved  against the
drafting party shall not be employed in the interpretation of this Agreement.

     15.13 Amendments. This Agreement may be amended only by the written consent
of both parties.

     15.14 Severability. In the event any provision of this Agreement is held by
a court of  competent  jurisdiction  to be  illegal  or  unenforceable,  (i) the
parties  shall  amend  this  Agreement  in  order to carry  out the  intent  and
essential  business  purposes of this Agreement as closely  possible  within the
requirements of applicable  provisions of Law as determined by such a court, and
(ii) the remaining provisions of this Agreement shall continue in full force and
effect.

     15.15 No Waiver. The waiver by either party to this Agreement of any one or
more defaults, if any, on the part of the other party, shall not be construed to
operate as a waiver of the other or future defaults under this Agreement.

     15.16  Captions.  Captions to paragraphs in this  Agreement are for ease of
reference, and shall not be considered an interpretation of the paragraph.

which this  Schedule 3 is  attached is  terminated  or  expires,  the  foregoing
Management  Fees  shall be  payable  to the MSO  based on all  Practice  Revenue

business day. The parties hereto may agree to handle such matters in a different
manner.

     For  purposes  of this  Agreement,  "Practice  Revenues"  shall  mean gross
collections  of all  revenues  generated  by or on behalf of the New PC (whether
through subsidiaries or affiliates), including, but not limited to, all fees and
charges collected as a result of professional  orthodontic services furnished to

                                    AFFIDAVIT

     I, Michael G. Churosh, D.D.S., declare:

     I am an orthodontist,  duly licensed in the State of Arizona and I practice
through a professional corporation under the name ______________ (the "New PC").

     I have had substantial  experience in the practice of the  Orthodontics and
in managing and operating an orthodontic office.

     In the course of operating orthodontic offices, I have acquired significant
knowledge as to the overhead  costs  incurred  and gross  receipts  generated by
similar  types  of  orthodontic  offices.  Further,  I am  fully  aware  of  the
non-orthodontic,  operational,  accounting,  billing, financing,  management and
personnel requirements of an orthodontic office and the cost factors involved in
providing  such  management,   personnel,  accounting,  billing,  financing  and
operation.

     I  have  thoroughly   reviewed  the  Management   Services  Agreement  (the
"Agreement"),  which is effective as of ________________,  1997, between the New
PC and Omega  Orthodontics of Goodyear,  Inc. (the "MSO") concerning the duties,
responsibilities and obligations undertaken by the MSO in managing and operating
all  non-orthodontic  aspects of the  Orthodontic  Office as contemplated by the
Agreement.

     I have reviewed the prior operating financial statements of the orthodontic
office located at 1105 North  Litchfield  Road,  Goodyear,  Arizona 85338 and an
operating  budget and estimated income of the orthodontic  office,  which, in my
opinion, can reasonably be expected from the operation of said office.

     In my  opinion,  based  upon my  experience,  the  Management  Fees of ____
Percent (___%) of "Practice  Revenues" to be charged by the MSO as  contemplated
by the Agreement,  will afford it a reasonable but not excessive  return for its
services rendered and obligations incurred. In addition, the New PC ____ Percent
( %) of  "Practice  Revenues"  retained by the New PC, will  provide  reasonable
earnings for the performance of orthodontic services.

     I declare under penalty of perjury that the foregoing statement is true and
correct to the best of my knowledge and belief.

     Executed at                , ________ this    day of           , 1997.

                                                   ____________________________
                                                   Michael G. Churosh, D.D.S.

                               SECURITY AGREEMENT


     THIS  SECURITY  AGREEMENT  is  effective  as of the ______ day of _________

corporation (the "MSO") with reference to the following facts:

     WHEREAS,  pursuant to a Management  Services  Agreement (the  "Agreement"),
dated as of the date hereof,  between the New PC and the MSO, as  assurance  and
collateral  security for the payment of the monthly  Management Fees owed to the
MSO pursuant to the Agreement and any funds  advanced by the MSO to or on behalf
of the  New PC  pursuant  to the  Agreement  and  for the  faithful  and  timely
performance  of all the covenants  and  conditions to be performed by the New PC
under  the  Agreement  (collectively,  the  "Obligations")  the New PC agreed to
pledge,  grant,  bargain,  assign and  transfer to the MSO a security  interest,
pursuant to the Uniform  Commercial  Code of the State,  in and to all  Practice
Revenue and the accounts receivable of patients of the New PC, together with all
proceeds thereof (collectively, the "Collateral");

     WHEREAS,  the New PC is obligated  as a condition to the MSO's  performance
under the Agreement to execute and deliver this Security Agreement;

     NOW, THEREFORE,  in consideration of the foregoing and of the covenants and
agreements hereinafter set forth, the parties hereto agree as follows:

     1. Grant of Security Interest.  As and for collateral  security for payment
by the New PC of the  Obligations  and any and all  amounts  payable  under this
Security Agreement (collectively,  the "Secured Obligations"), the New PC hereby
pledges, grants,  bargains,  assigns and transfers to the MSO, and grants to the
MSO a security  interest in, the Collateral.  Dr. Churosh shall cause the New PC
to perform  fully and on a timely  basis all of the New PC's  obligations  under
this Security  Agreement.  The MSO may at its option file a financing  statement
(Form UCC-1) in order to perfect its security interest hereunder.

     2.  Representations and Warranties.  The New PC represents and warrants all
of the accounts  receivable  constituting a portion of the Collateral of the New
PC pledged to the MSO are and will be validly created obligations of each of the
obligors who incurred same for services actually rendered in the ordinary course
of business of the New PC. Further,  the New PC represents and warrants that the
Collateral is not subject to any lien, pledge,  charge,  encumbrance or security
interest or right or option on the part of any third person.

     3. Release of Security Interest.  Upon the termination of the Agreement and
payment in full of the accrued  Management Fees thereunder and any and all other
Secured Obligations,  the MSO shall release its security interest hereunder, and
will deliver to the New PC any property forming part of the Collateral delivered
to the MSO and then held by the MSO hereunder.

     4.  Realization  of  Collateral.  The MSO shall have,  with  respect to the
Collateral,  the rights and


                                       34
<PAGE>


obligations of a secured party under the Uniform  Commercial  Code as adopted in
the  state  of  Arizona  (the  "State").  Such  rights  shall  include,  without
limitation, the following:

     A. The right,  upon default,  to have the Collateral,  or any part thereof,
transferred to its own name or to the name of its nominee;

     B. The  right,  upon  default,  to sell,  assign or  deliver as much of the
Collateral  as is  reasonably  necessary  to repay  the  defaulted  indebtedness
(together with expenses  attendant upon such sale and  repayment),  at public or
private  sale,  as the MSO may  elect,  either  for cash or on  credit,  without
assumption  of any  credit  risk and  without  demand or  advertisement  (unless
otherwise required by law).

     C.  The New PC  hereby  irrevocably  authorizes  the MSO to sign  and  file
financing  statements naming the New PC as the debtor and the MSO as the secured
party, at any time with respect to any Collateral,  without the signature of the
New  PC.  The  New PC  hereby  irrevocably  appoints  the  MSO as the  New  PC's
attorney-in-fact,  with full  authority in the place and stead of the New PC and
in the name of the New PC,  from time to time in the MSO's  discretion,  to take
any action and to execute any  instrument  which the MSO may deem  necessary  or
advisable to accomplish the purposes hereof. The attorney-in-fact granted herein
is coupled with an interest and is  irrevocable.  Third parties and entities and
persons  not a party to this  Security  Agreement  are  entitled to rely on this
attorney-in-fact  and an affidavit of the MSO attesting thereto.  The acceptance
of this  appointment  by the MSO shall not  obligate  it to perform  any duty or
covenant  required  to be  performed  by the New PC  under or by  virtue  of the
Collateral. Notwithstanding the foregoing power of attorney, the New PC shall at
any  time  on the  request  of the  MSO,  sign  Financing  Statements,  security
agreements or other agreements with respect to any Collateral. Upon the New PC's
failure  to  sign  said  Financing  Statements,  security  agreements  or  other
agreements,  the MSO is  authorized  as the agent of the New PC to sign any such
instruments.  Upon the  request of the MSO,  the New PC agrees to pay all filing
fees and to  reimburse  the MSO on demand for all costs and expenses of any kind
(including,  without  limitation,  legal fees) incurred in any way in connection
with the Collateral.

     5.  Purchase  of  Collateral.  At any such  private  or public  sale of the
Collateral  or  part  thereof,  the  MSO may  purchase  and pay for the  same by
cancellation of such portion of the Obligations, equal to the purchase price and
free of any  right  of  redemption  on the part of the New PC.  the MSO  agrees,
however,  that the New PC shall  have all  rights,  including  rights of notice,
provided by the  Uniform  Commercial  Code as adopted in the State.  In any case
where notice is required,  five days' notice shall be deemed reasonable  notice.
In the event of any sale  hereunder,  the MSO shall  apply the  proceeds  in the
order set forth  below in  Paragraph  6 hereof.  the MSO may have  resort to the
Collateral or any portion thereof with no requirements on the part of the MSO to
proceed first against any other person or property.

     6.  Application of Collateral.  Proceeds from the sale of the Collateral or
any part thereof shall be applied by the MSO in the following order:

     A. To the payment of the costs and expenses of  collection  incurred by the
MSO,  including,  without  limitation,  attorneys' fees and all other reasonable
expenses, liabilities and costs incurred by the MSO in connection therewith;


                                       35

     C. To the payment in full of all other  Obligations of the New PC under the
Agreement; and

     D. To the payment to the New PC of any  surplus  then  remaining  from such
proceeds.

     7.  Extension of Agreement.  No renewal or extension of the  Agreement,  no
release  or  surrender  of  any  Collateral  given  as  security  in  connection
therewith,  and no delay in  enforcement  thereof or in exercising  any right or
power with respect  thereto or hereunder shall affect the rights of the MSO with
respect to the Collateral or any part thereof.

     8.  Notices.  Any notice to be given  pursuant to this  Agreement  shall be
deemed  effective  the same day when  such  notice  is given  personally,  or by
telegram,  or  electronic  transmission  to the  President  of the party to whom
notice is being given. Notice by mail shall be deemed effective three days after
deposit in the United States mail, and properly addressed with postage prepaid.

                                    EXHIBIT E


                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A.Method of Invoking ADR Procedures

     1. These procedures may be invoked by any party to an agreement which
incorporates these procedures by giving written notice to the other of the
dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties, each acting through its representative, shall meet at a
mutually acceptable time and place within five business days after the
non-disputing party designates its representative to the other. At that meeting,
the parties shall attempt in good faith to negotiate a resolution of the
dispute, or failing that, to agree on a method for resolving the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer period of time as the parties may mutually agree, the parties have not
succeeded in negotiating a resolution of the claim or dispute or agreeing on a
dispute resolution mechanism, they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

     4. The parties will jointly appoint a mutually acceptable mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above, then the parties shall select a neutral third party from
the Center for Public Resources, New York, New York ("CPR") Panels of Neutrals,
with the assistance of CPR, unless the parties agree otherwise in finding a
mutually acceptable mediator.

     5. The New PC and the MSO shall each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR.

     6. The parties agree to participate in good faith in the mediation and
negotiations related thereto for a period of thirty (30) days from appointment
of a mediator by any of the parties or the CPR.


B. Mediation procedures

     1. The mediator shall be neutral and impartial.


                                       39
<PAGE>


     2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.


     (a)  The mediator is free to meet and communicate separately with each
          party.

     (b)  The mediator will decide when to hold joint meetings with the parties
          and when to hold separate meetings. There shall be no stenographic
          record of any meeting. Formal rules of evidence will not apply.

     (c)  The mediator may request that there be no direct communication between
          the parties or between their attorneys without the concurrence of the
          mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its officers and an attorney. Each party will have a representative fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator will not transmit information received from any party to
another party or any third person unless authorized to do so by the party
transmitting the information.

     6. The entire process is confidential. The parties and the mediator will
not disclose information regarding the process, including settlement terms, to
third persons, unless the parties otherwise agree. The process shall be treated
as a compromise negotiation for purposes of the Federal Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing administrative and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

     (a)  The mediator will be disqualified as a witness, consultant or expert
          in any pending or future investigation, action or proceeding relating
          to the subject matter of the mediation (including any investigation,
          action or proceeding which involves persons not party to this
          mediation); and

     (b)  The mediator and any documents and information in the mediator's
          possession will not be subpoenaed in any such investigation, action or
          proceeding, and all parties will oppose any effort to have the
          mediator and documents subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the


                                       40
<PAGE>


parties and the mediator otherwise agree in writing.

     10. The mediator, if a lawyer, may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons, (ii) if the mediator believes that a party
is not acting in good faith, or (iii) if the mediator concludes that further
mediation efforts would not be useful.

C. Binding Arbitration If the parties do not resolve the dispute through
mediation within the period provided in Part A above, the parties shall submit
the matter to binding arbitration in Boston, Massachusetts before a qualified
sole arbitrator in accordance with the then current CPR Rules for
Non-Administered Arbitration of Business Disputes. If the party initially
raising the dispute to be resolved is New PC or Dr. Churosh, the arbitration
shall be held in Boston, Massachusetts, and if the party initially raising the
dispute to be resolved is the MSO or OMEGA, the arbitration shall be held in
Goodyear, Arizona. The sole arbitrator shall be agreed upon by the parties
within twenty (20) days after either party elects to submit any issue to
arbitration or, failing that, shall be selected by CPR. A qualified arbitrator
is one who is familiar with the principal subject matter of the issues to be
arbitrated such as by way of example, healthcare services industry matters,
management consulting services generally or business law/corporate matters
generally. Judgment upon the award rendered by the arbitrator may be entered in
any court having jurisdiction. The arbitrator shall not have the authority to
award multiple, punitive or consequential damages under any circumstances.

      WHEREAS, OMEGA provides professional  management and marketing services to

practice management  systems,  office space,  equipment,  furnishings and active
administrative  personnel  necessary for the operation of orthodontic  practices
and are provided directly or indirectly through management service organizations
such as the MSO;

      WHEREAS, OMEGA and Clark E. Schneekluth, D.D.S. ("Dr. Schneekluth") who is

      WHEREAS, the MSO was formed and acquired to provide equipment,  facilities
and personnel to, and to manage the non-orthodontic business affairs of, the New

      WHEREAS,  the New PC wishes to retain the MSO to perform the functions and
to provide the  services  described  in this  Agreement  to assist the New PC to

                                      TERM



<PAGE>

      1.1 The initial term of this  Agreement  shall  commence on the date first
above  written  and  continue  for a period of twenty  (20) years (the  "Initial

New PC prior to  expiration  of the Initial Term or any then  effective  Renewal
Term.

                                    ARTICLE 2

      2.1 General. The MSO shall provide the New PC with comprehensive  practice
management,  financial and marketing services,  and such facilities,  equipment,
and support  personnel as are  reasonably  required by the New PC to operate its
orthodontic  practice at the  Orthodontic  Offices,  as determined by the MSO in
consultation with the New PC. The New PC hereby appoints the MSO as the sole and
exclusive  business manager of the New PC and agrees that the MSO shall have all
power and authority reasonably necessary to manage the non-orthodontic  business
affairs  of the New PC and carry out the MSO's  orthodontic  duties  under  this
Agreement, subject to the requirements of the applicable provisions of State law
relating to the practice of orthodontics. The MSO may perform some or all of its
services at a location other than at the Orthodontic Offices.

      2.2 Orthodontic Office Services.  The MSO shall provide or arrange for the
provision of the office space and related  leasehold  improvements to constitute
the Orthodontic Offices and related fixtures, furniture, furnishings,  equipment

from time to time. The MSO shall be responsible for all repairs, maintenance and
replacement of the Orthodontic  Offices  including such leasehold  improvements,
fixtures, furniture,  furnishings and equipment, except for repairs, maintenance
and replacement  necessitated by the negligence of the New PC, its employees and
agents (not including the MSO or its employees or agents).  The MSO shall, on an
ongoing  basis,  evaluate and consult with the New PC on the equipment  needs of
and the  efficiency  and  adequacy  of the  Orthodontic  Offices.  The MSO shall
provide   telephone,   facsimile   transmission,   printing,   duplicating   and
transcribing services as needed, as well as all laundry, linen and uniforms.

      2.3 Administrative Services.

      (a)  The MSO  shall  supply  secretarial,  reception,  maintenance,  front

MSO shall be  responsible  for staff  scheduling,  provided,  however,  that all
Practice  Providers  including  orthodontic  assistants and hygienists  shall be
under the direct supervision of the New PC. The New PC shall have sole authority
to employ and terminate the employment of all Practice Providers.  All personnel
placed in the Orthodontic Offices by the MSO shall be subject to the approval of
the New PC, which approval shall not be  unreasonably  withheld,  and the New PC
shall have the authority to instruct the MSO to terminate the employment of such
personnel for any lawful reason.  The MSO shall be responsible for all personnel
wages,

compliance with the compensation provisions of this Agreement.

to practice dentistry and/or orthodontics in the State including Dr. Schneekluth

New PC or  otherwise  under  contract  with  the  New PC to  provide  dental  or
orthodontic,  hygienic or other assistance or services to patients of the New PC
or otherwise  required by applicable "Laws" (as defined in Section 2.6 below) to
be employees of the New PC to provide  services to patients of the  Practice.  A
list of all Practice Providers and their relationship to the New PC is set forth
as Exhibit B attached  hereto and  incorporated  herein by  reference.  Prior to
making any changes in the list of Practice  Providers,  the New PC shall use its
best efforts to consult with the MSO. The New PC also shall use its best efforts
to  consult  with the MSO with  regard to the terms of  contracts  entered  into
between the New PC and the Practice  Providers  and the terms and  conditions of
their employment or engagement as independent contractors.

      2.4 Business  Systems,  Procedures and Forms. In consultation with the New
PC, the MSO shall establish standardized business systems and procedures for the
New PC, including,  but not limited to, patient  scheduling  systems,  treatment
records  system,  financial  reporting and process  control  systems and patient
communication  management systems (the "OMEGA Patient  Scheduling  System") that
are designed to improve the New PC operating  efficiency.  The MSO shall analyze
such  information  on an ongoing  basis in order to advise the New PC on ways of
improving operating efficiencies. The MSO shall provide training to the staff of
the New PC in the  implementation  and operation of such  standardized  business
systems and procedures.  The MSO shall additionally  provide the New PC with and
train the New PC's staff in the use of standardized  clinical forms,  including,
without  limitation,  forms for patient evaluations and treatment plans. The New
PC expressly  acknowledges  and agrees that it shall have no property  rights in
the OMEGA Patient Scheduling System and the other foregoing systems,  procedures
and clinical forms, and further agrees that such systems,  procedures, and forms
shall be deemed to  constitute  Confidential  Information  within the meaning of
Section 3.8 hereof and be subject to the restrictions on the use, appropriation,
and reproduction of such Confidential Information provided for in Section 3.8.

      2.5 Purchasing,  Accounts Payable, Supplies and Inventory Control. The MSO
shall be  responsible  for and shall  establish  and  maintain  systems  for the
handling and  processing of all  purchasing  and payment  activities and for the
performance of all payroll and payroll  accounting  functions of the New PC. The

as reasonably  required by the New PC to enable the New PC to render orthodontic
care to its patients including,  without limitation,  all orthodontic appliances

      2.6 Regulatory Compliance Services.  The MSO shall arrange for or cause to
be  rendered  to the New PC  such  business,  legal  and  regulatory  management

and directly  related to the  operations  of the New PC or its  compliance  with
Federal, state or local laws, rules, regulations or interpretations governing or
applicable to the New PC (collectively, "Laws"); provided, however, that the MSO
shall not be  responsible  for any  services  related  to  malpractice  or other
professional  service claims or matters not directly related to the operation of
the New PC or its  compliance  with  Laws,  or for any  legal or tax  advice  or
services or personal financial services to Dr.

Schneekluth and the  Orthodontists  (if any) or any employee or agent of the New
PC.

      2.7 Billing, Collection. The MSO shall be responsible for: (i) billing and
collecting payments for all orthodontic and other professional services rendered
by the New PC and the Practice  Providers,  with all such billing and collecting
to be done in the name of the New PC; (ii)  receiving  payments  from  patients,
insurance companies and all other third party payors; (iii) taking possession of
and  endorsing  in the  name  of the New PC any  notes,  checks,  money  orders,

accounts receivable; and (iv) settling and compromising claims and, where deemed
appropriate by the MSO and consented to (which consent shall not be unreasonably
withheld  or  delayed)  by the  Practice  Provider  rendering  the  professional
services which resulted in the applicable  accounts  receivable,  assigning such
accounts  receivable  to a  collection  agency or the bringing of a legal action
against a patient  or a payor on the New PC's  behalf.  In seeking  payments  on
behalf  of the New PC  hereunder,  the MSO  shall  act as the New PC's  agent in
billing and collecting professional fees, charges and other accounts owed to the
New PC and shall only bill under the New PC's provider  number.  In this regard,
the New PC appoints the MSO for the Term of this  Agreement in  accordance  with
the provisions of Article 11 hereof as its true and lawful  attorney-in-fact for
the purposes  set forth above in this Section 2.7 and in Section 2.8 below.  The
MSO does not guarantee collection and is not responsible for any loss to the New
PC as a result of any inability to collect fees and charges.

      2.8 Disbursement of Funds.

      (a) All monies collected for the New PC by the MSO pursuant to Section 2.7
above shall be deposited  into an account (the "the New PC Account") with a bank
whose deposits are insured with the Federal  Deposit  Insurance  Corporation and
which  bank is  acceptable  to the MSO and the New PC (the  "Bank").  The New PC
Account  shall  contain  the  name of the New PC,  but the MSO  shall  make  all
disbursements  therefrom. The MSO shall account for all monies so disbursed from
the New PC Account.

      (b)  From  the  funds  collected  and  deposited  by the MSO in the New PC
Account,  the MSO  shall  make  for and on  behalf  of the New PC the  following
disbursements promptly, when payable:

            (1)  Compensation,  including  salaries,  benefits  and other direct
      costs payable to Dr.  Schneekluth and the  Orthodontists  (if any) and the
      other  Practice  Providers  of the New PC, and all  withholding  taxes and
      assessments payable to Federal,  state and local governments in connection
      with the employment of such personnel; and

            (2) All  compensation  payable  to the MSO  pursuant  to  Article  6
      hereof.

      (c) In the  event  the funds in the New PC  Account  will,  at any time be
insufficient  to cover  the  current  portion  of the  foregoing  expenses  when
payable,  the MSO  will  advance  to the New PC the  necessary  funds to pay the
current  portion of such expenses for the benefit of the New PC, which  advances
will be deemed to be loans to the New PC to be repaid without  interest from the
New PC Account at such times as there are  adequate  funds  therein or upon such
other  terms and at such  times as  agreed  to by the New PC and the MSO,  which
indebtedness shall not be deemed an MSO Expense for purposes of Section 2.9.

New PC. The MSO shall collect all information and determine,  to the best of its

of the New PC, all prepared by or with the assistance of an accountant chosen by
the MSO. At the end of each fiscal year of the New PC, the MSO shall arrange for
a  financial  statement  with  respect to the New PC to be prepared by the MSO's
accountant.  At the New PC's request,  the MSO shall prepare reports  indicating
the gross revenues,  number of patients,  type of patients, and the activity and
the  productivity  of the New PC. The MSO 


                                       6
<PAGE>

shall assist and advise the New PC in the financial management of the New PC.

      2.12  Marketing.  The MSO shall  design and  execute a  marketing  plan to
promote the New PC's professional services. The MSO shall also make available to
the New PC all brochures,  contracts,  and other materials reasonably related to

stationery,  printing and postage costs in connection  therewith.  In connection
with  such  marketing  plan,  the  MSO  shall  advise  Dr.  Schneekluth  and the
Orthodontists  (if any) on  establishing  and  maintaining  a plan for patients'
payments for orthodontic  services on an installment  plan basis.  All marketing
activities  hereunder  shall be conducted in compliance with all applicable Laws
governing advertising by the orthodontic profession.

      2.13  Complaints.  The  MSO  shall  assist  the  New  PC in  handling  all
complaints,  grievances  and  disputes  involving  the New PC and  the  Practice
Providers  and any  patients or third  parties.  However,  the MSO shall have no
control  over the New  PC's  patients.  All  decisions  concerning  the New PC's
patients shall be made by the New PC and the Practice Providers.

      2.14 Practice Laws.  Notwithstanding any provision in this Agreement,  the
MSO shall not take any action in  connection  with the  services  to be rendered
hereunder that violates any Law, including,  without limitation, the performance

Professions  Code  of  the  State  as it  relates  to  professional  orthodontic
practices.

      2.15 Monthly  Meetings.  The MSO shall  initiate  monthly or more frequent

Orthodontists  (if any) shall keep the MSO  informed of  retirement  goals on an
ongoing basis.  Upon request of the New PC, the MSO will conduct a search for an
appropriate  orthodontist  and  other  professionals  (collectively,   "Practice
Associates") for the purposes of accommodating practice growth,  reducing doctor
work schedule,  or planned retirement.  Such search shall include use by the MSO
of a national  journal  advertising  program and networking in the profession to
locate  appropriate  Practice  Associates.  The MSO estimates that it could take
approximately two years for such a search.

assist  the New PC with a trial  plan of  approximately  six  months for the new
Practice  Associate(s).  It is understood  that at the end of this period either
the New PC or the new Practice  Associate may terminate  the  relationship.  All
such Practice  Associates  recruited by the MSO as may be accepted by the New PC
shall be employees of the Practice (if so employed)  and not of the MSO. The MSO
will confer with the New PC on an appropriate salary/work-in arrangement for the
new Practice Associate and the final arrangements shall be determined by the New
PC.

                              DUTIES OF THE NEW PC

      3.1 General.  The New PC shall be  responsible  for the  management of its
practice and the Orthodontic  Office, in accordance with the requirements of the
Laws of the State.

      3.2 Employment of the Orthodontists and Rendering of Patient Care. The New
PC shall be responsible for the employment and  professional  supervision of Dr.
Schneekluth  and all  Orthodontists  and the other  Practice  Providers  and all
orthodontic  care rendered to patients shall be rendered by Dr.  Schneekluth and
such  Orthodontists.  Additionally,  the New PC  shall  be  responsible  for the
professional  supervision of all other Practice  Providers in their rendering of
patient care.

      3.3 Professional Services. The New PC shall use and occupy the Orthodontic
Offices  designated  on  Schedule  2 hereof  exclusively  for the  practice  and
rendering of orthodontic services, and shall comply with all applicable Laws and
all standards of orthodontic  care. It is expressly  acknowledged by the parties
that the  orthodontic  practice  conducted at the  Orthodontic  Offices shall be
conducted solely by Dr. Schneekluth and the Orthodontists and the other Practice
Providers  acting under the supervision  and control of Dr.  Schneekluth and the
Orthodontists (if any), and no other  orthodontist  shall be permitted to use or
occupy the Orthodontic Offices.  The New PC shall provide professional  services
to patients hereunder in compliance at all times with ethical standards and Laws
applying  to the  orthodontic  profession.  The New PC  shall  ensure  that  Dr.
Schneekluth and each Orthodontist who provides  orthodontic services to patients
is  licensed  by  the  State.  In  the  event  that  any  disciplinary,  medical
malpractice  or other  actions  are  initiated  against Dr.  Schneekluth  or any
Orthodontist or other Practice Provider, the New PC shall immediately inform the
MSO of such action and the underlying  facts and  circumstances  subject to such
confidentiality  agreement  or  arrangements  as the New PC and  the  MSO  shall
mutually determine at or prior to the time of such disclosure. The New PC agrees
to  cooperate  with and  participate  in  quality  assurance/utilization  review
programs  established  by the MSO or mandated  by  accreditation  and  licensure
standards applicable to the practice of orthodontics. Deficiencies discovered in
the  performance  of any  personnel or in the quality of  professional  services
shall be reported  immediately to the MSO, and appropriate  steps shall be taken
by the New PC at once to remedy such deficiencies.



                                       8
<PAGE>

      3.4 Records.  The New PC will keep or cause to be kept accurate,  complete
and timely  dental and other  records of all  patients.  The  management  of all
dental and patient  files and records  shall  comply  with all  applicable  Laws
regarding their confidentiality and retention and all files and records shall be
located so that they are readily  accessible for patient care,  consistent  with
ordinary  records  management  practices.  Such records  shall be  sufficient to
enable the MSO, on behalf of the New PC, to obtain  payments  for  services  and
related  charges and to facilitate  the delivery of quality  patient care by the
New PC.  Notwithstanding  the  foregoing,  patient  dental  records shall be and
remain the property of the New PC and the contents  thereof  shall be solely the
responsibility of the New PC.

      3.5 Professional  Expenses. The New PC shall be solely responsible for the
cost of professional  licensure fees and board certification fees, membership in
professional associations and continuing professional education incurred by each
Orthodontist  and other  Practice  Provider  employed  by the New PC. The New PC
shall ensure that Dr. Schneekluth and all the Orthodontists  employed by the New
PC participate in such continuing  education as is necessary for Dr. Schneekluth
and such the Orthodontists to remain current.

      3.6 Professional Liability Insurance. The New PC shall provide, or arrange
for the  provision  of,  and  maintain  throughout  the Term of this  Agreement,
professional  liability  insurance coverage in accordance with the provisions of
Article 9 hereof. The New PC shall also cooperate in any programs recommended by
the MSO to assure  that each of its  Orthodontists  is  insurable,  and that Dr.
Schneekluth  and each  Orthodontist  participates in an on-going risk management
program.

      3.7 Employment  Agreement.  The parties  recognize that the services to be
provided  by the  MSO  are  feasible  only  if the  New PC  operates  an  active
orthodontic  practice  to  which  it,  Dr.  Schneekluth  and  each  Orthodontist
associated  with the New PC devote their full time and  attention,  unless other
specific  provisions are made in writing and mutually agreed upon by the MSO and
New PC. The New PC will cause Dr.  Schneekluth and each individual  Orthodontist
who now is or  hereafter  becomes  affiliated  with the New PC to  enter  into a
written employment agreement (the "Employment  Agreement")  satisfactory in form
and substance to the MSO, pursuant to which Dr.  Schneekluth or the Orthodontist
shall agree not to establish, operate or provide orthodontic or dental services,
without the prior written  consent of both the New PC and the MSO, at any office
or facility other than the  Orthodontic  Office.  In addition,  such  Employment
Agreement shall provide by its own terms or by a separate  agreement that if Dr.
Schneekluth's or such  Orthodontist's  employment shall terminate for any reason
during  the  Term of  this  Agreement,  for a  period  of 24  months  after  the
termination of Dr.  Schneekluth's or such  Orthodontist's  Employment  Agreement
with  the New PC,  Dr.  Schneekluth  or such  Orthodontist  shall  agree  not to
establish,  operate or provide orthodontic or dental services, without the prior
written  consent  of both  the New PC and the MSO,  at any  office  practice  or
facility  whatsoever  providing services similar to those provided by the New PC
at any  orthodontic  office within a fifteen (15) mile radius.  Such  Employment
Agreement (or separate  agreement) shall also provide,  among other things, that
in the event of a breach of Dr.  Schneekluth's or the  Orthodontist's  agreement
not to compete with the New PC provided  for in such  Employment  Agreement  (or
separate agreement),  the MSO shall be entitled to receive, in addition to other
remedies and not by way of an election of remedies,  liquidated damages equaling
the greater of: (a) Dr. Schneekluth's or such Orthodontist's income, as shown on
the W-2 form prepared by the New PC, for the most recent  calendar  year; or (b)
$300,000.  Such  payment  shall  be made  to the  MSO by the New PC  immediately
following  receipt  of  the  payment  from  Dr.  Schneekluth  or  the  breaching
Orthodontist  by the New PC. Each of 


                                       9
<PAGE>

the MSO and OMEGA shall be expressly named as a third-party  beneficiary to such
agreements  between the New PC and Dr. Schneekluth and each Orthodontist and the
rights and remedies of the MSO and OMEGA  thereunder  or otherwise in respect of
the restrictive covenants set forth in such agreements shall survive termination
of this Agreement.

      3.8 Confidentiality. The New PC agrees and acknowledges that all materials
provided by the MSO to the New PC constitute "Confidential  Information" and are
disclosed in confidence and with the understanding that it constitutes  valuable
business information  developed by the MSO with the assistance of OMEGA at great
expenditures of time,  effort and money. The New PC further agrees that it shall
not,  directly or indirectly,  without the express prior written  consent of the
MSO, use or disclose such Confidential Information for any purpose other than in
connection  with the  services  to be  rendered  hereunder.  The New PC  further
agrees:  (i) to keep strictly  confidential  and hold in trust all  Confidential
Information and not disclose such  Confidential  Information to any third party,
including its shareholders, directors, officers, affiliates, partners, employees
and  independent  contractors  without the express prior written  consent of the
MSO; and (ii) to impose this obligation of  confidentiality on its shareholders,
directors,   officers,   affiliates,   partners,   employees   and   independent
contractors.  The  New PC  acknowledges  that  the  disclosure  of  Confidential
Information  to it by the MSO is done in reliance upon its  representations  and
covenants in this Agreement. Upon expiration or termination of this Agreement by
either party for any reason whatsoever,  the New PC shall immediately return and
shall  cause  its  shareholders,   directors,  officers,  affiliates,  partners,
shareholders  and independent  contractors to immediately  return to the MSO all
Confidential  Information,  and  the  New  PC  will  not,  and  will  cause  its
affiliates,  partners,  employees and independent contractors not to, thereafter
use, appropriate, or reproduce such Confidential Information. The New PC further
expressly   acknowledges  and  agrees  that  any  such  use,   appropriation  or
reproduction of any such Confidential  Information by any of the foregoing after
the  expiration or  termination  of this  Agreement  will result in  irreparable
injury to the MSO and OMEGA,  that the remedy at law for the foregoing  would be
inadequate,  and  that  in  the  event  of  any  such  use,  appropriation,   or
reproduction  of any such  Confidential  Information  after the  termination  or
expiration  of this  Agreement,  the MSO and  OMEGA,  in  addition  to any other
remedies or damages  available  to either or both of them,  shall be entitled to
injunctive or other  equitable  relief  without the necessity of proving  actual
damages  but such  rights to relief  shall not  preclude  the MSO and OMEGA from
other remedies which may be available to either or both of them hereunder.

                 PROFESSIONAL SERVICES, CONTROL OF SOLICITATION,
              APPROVAL OF ADVERTISING MATERIAL AND NO RECIPROCATION


      4.1 A  fundamental  understanding  between the parties  hereto is that the
rendering of  orthodontic  services shall be separate and  independent  from the
provision of  administrative,  management and support services by the MSO. Thus,
the  New PC  shall  have  sole  and  absolute  control  of the  delivery  of all
professional  services  and  treatment  rendered to patients at the  Orthodontic
Offices.

      4.2 No employee or other representative of the MSO shall be engaged in, or
allowed to solicit patients on behalf of, the New PC, nor shall the MSO have any
control over the New PC's patients.

      4.3 No  advertising or promotional  materials,  or other  materials of any
nature,   including   billing  and  collection   forms,   reports,   agreements,
correspondence,  or similar materials,  used in connection with the New PC shall
be used or distributed without having first been approved by the New PC.

      4.4 The parties hereby  acknowledge and agree that the benefits  conferred
upon each of them hereunder  neither  require nor are in any way contingent upon
the  admission,  recommendation,  referral,  or any  other  arrangement  for the
provision  of any item or service  offered by the MSO to any patients of the New
PC or its shareholders,  officers, directors, employees,  contractors or agents,
nor are such benefits in any way contingent upon the recommendation, referral or
any other  arrangement  for the provision of any item or service  offered by the
New PC or any of its Practice Providers, employees, contractors or agents.

      5.1 In  consideration of the sums to be paid to the MSO under the terms of
this Agreement, the MSO hereby leases or sub-leases,  as applicable,  to the New
PC during the Term of this Agreement the Orthodontic  Offices, and the leasehold
improvements and fixtures, furniture and equipment at the Orthodontic Offices as
listed from time to time on Schedule 2 attached hereto and  incorporated  herein
by this reference, under the following terms and conditions:

      (a) The MSO is the  lessee by  assignment  under  lease  for the  premises
occupied by the New PC  (collectively,  the  "Master  Lease") a copy of which is
attached hereto as Exhibit A and incorporated herein by this reference.  The New
PC hereby  acknowledges  that the premises  described under the Master Lease are
suitable for the New PC's  orthodontic  practice.  Based and contingent upon the
New PC's  promise to timely pay all  amounts due under this  Agreement,  the MSO
hereby  agrees to sublease the leased  premises to the New PC upon the following
terms and conditions:

            (i) This  sublease  between  the MSO and the New PC of the  premises
      shall be subject to all of the terms and  conditions  of the Master Lease.
      In the event of the  termination of the MSO's interest as lessee under the
      Master  Lease for any  reason,  then the  sublease  created  hereby  shall
      simultaneously terminate,  unless the New PC assumes the obligations under
      the Master Lease in question and the Lessor consents thereto.

            (ii) All of the terms and  conditions  contained in the Master Lease
      are incorporated herein as terms and conditions of the sublease (with each
      reference  therein to "Lessor" and  "Lessee," to be deemed to refer to the
      MSO and the New PC,  respectively)  and, along with the provisions of this
      Section 5.1(b) and Exhibit "A," shall be the complete terms and conditions
      of the sublease created hereby.

            (iii) Notwithstanding the foregoing,  as between the MSO and the New
      PC, the MSO shall  remain  responsible  for  meeting  the  obligations  of
      "Lessee" under the sections  entitled Rent,  Additional  Rent  Adjustment,
      Insurance  on Fixtures,  Liability  Insurance,  Repairs,  and Taxes of the
      Master Lease,  all of which  obligations  shall be considered MSO Expenses
      hereunder and the New PC shall have no monetary obligation in that regard.
      In  addition,  as between the MSO and the New PC, the MSO shall retain the
      right to exercise any options to purchase the  premises,  or other similar
      rights of ownership or  possession,  which may be granted under the Master
      Lease, and the New PC shall have no rights in that regard.

            (iv) In the event this  Agreement  is  terminated  according  to its
      terms, this sublease shall also terminate automatically.

            (v) If the  Master  Lease  contains  an  option  to renew  the terms
      thereof,  the MSO shall  notify  the New PC, at least 30 days prior to the
      expiration of the time for exercising such option,  of 



                                       12
<PAGE>

      the  MSO's  intention  to  renew  or not to renew  such  term.  If the MSO
      determines  not to renew such term,  the MSO shall  provide or arrange for
      the  provision of  comparable  office space (the  "Substitute  Orthodontic
      Office")  within a radius  of 15 miles of the  Orthodontic  Office,  which
      Substitute  Orthodontic Office shall be subject to the approval of the New
      PC (which  approval shall not be  unreasonably  withheld or delayed).  The
      lease or sublease for such Substitute  Orthodontic  Office, as applicable,
      shall be substituted  for the lease  described on Exhibit A hereto and all
      references  to the "Master  Lease" shall  thereafter  be applicable to the
      lease or sublease for the  Substitute  Orthodontic  Office for purposes of
      this Agreement, ab initio.

            (vi) The  Alternative  Dispute  Resolution  provisions  set forth in
      Article 14 of this Agreement shall not apply to any issues  concerning the
      Sub-Lease,  the New PC's  tenancy  or the MSO's  rights  and  remedies  as
      Sub-Lessor.

      5.2 The MSO  shall  provide  the New PC at the  Orthodontic  Offices  such
additional  leasehold  improvements,   fixtures,   furniture,   furnishings  and
equipment as may be mutually  agreed to with the New PC and reflected  from time
to time on a  supplement  to  Schedule  2  hereto.  The use by the New PC of all
leasehold improvements,  fixtures, furniture, furnishings and equipment provided
hereunder shall be subject to the following conditions:

      (a)  Title  to all such  leasehold  improvements,  fixtures,  furnishings,
furniture and  equipment  shall remain in the MSO and upon  termination  of this
Agreement,  the New PC shall immediately return and surrender all such leasehold
improvements,  fixtures,  furniture,  furnishings and equipment to the MSO in as
good condition as when received, normal wear and tear excepted.

      (b) The MSO shall be fully and  entirely  responsible  for all repairs and
maintenance of all such leasehold improvements, fixtures, furniture, furnishings
and equipment;  provided,  however,  that the New PC agrees that it will use its
best  efforts to prevent  damage,  excessive  wear,  and  breakdown  of all such
leasehold  improvements,  fixtures,  furniture,  furnishings and equipment,  and
shall advise the MSO of any and all needed repairs and equipment failures.

      (c) The  obligation  of the MSO to  provide  the  leasehold  improvements,
fixtures, furniture, furnishings and equipment stated herein shall be concurrent
and co-extensive with the Term of this Agreement.

      5.3. No Warranty.

      (a)  THE  NEW  PC  ACKNOWLEDGES  THAT  THE  MSO  MAKES  NO  WARRANTIES  OR
REPRESENTATIONS,  EXPRESS OR IMPLIED,  AS TO THE  SUITABILITY OR ADEQUACY OF ANY
LEASEHOLD IMPROVEMENTS,  FIXTURES, FURNITURE, FURNISHINGS,  EQUIPMENT, INVENTORY
OR SUPPLIES  PROVIDED OR LEASED OR SUBLEASED  PURSUANT TO THIS AGREEMENT FOR THE
CONDUCT OF AN ORTHODONTICS PRACTICE OR FOR ANY OTHER PARTICULAR PURPOSE.

      (b) Nothing in this Agreement shall be construed to affect or limit in any
way the  professional  discretion  of the  Practice  Providers to select and use
fixtures, furniture, furnishings and equipment, inventory and supplies purchased
or provided  by the MSO in  accordance  with the  provisions  of this  Agreement
insofar as such selection or use constitutes or might constitute the practice of
dentistry or orthodontics.

                                    COMPENSATION


      As consideration  for the performance of all of its duties and obligations
as  provided  in this  Agreement,  including  but not  limited to, the costs and
expenses  associated  with  furnishing  the  services,  personnel,   facilities,
leasehold improvements, fixtures, furniture, furnishings, equipment, inventories
and supplies provided for herein, the MSO shall receive compensation in the form
of monthly  management fees (the  "Management  Fees") based upon a predetermined
percentage of the "Practice  Revenues",  as defined and determined in accordance
with the  provisions  set forth in Schedule 3 attached  hereto and  incorporated
herein by this reference,  as such Schedule may be amended by the New PC and the
MSO from time to time. It is acknowledged by and between the parties hereto that
the MSO and/or its  affiliates  has (have)  incurred  substantial  expenses  and
future  obligations  in  acquiring  the capital  stock of the MSO,  acquiring or
otherwise  establishing  the  Orthodontic  Offices,  establishing  its  systems,
including fees for consultants and other professionals,  interest expense, lease
obligations,  and costs of furnishing or refurbishing  the premises at which the
Orthodontic   Offices  are  located.   The  MSO  has  also  assumed  substantial
obligations associated with the continuing operation of the Orthodontic Offices,
including  those of  lessee,  obligor  and  guarantor  and  obligor  on loans to
establish and operate the Orthodontic  Offices. The parties,  therefore,  having
considered various  compensation  formulae,  acknowledge and agree that in order
for the MSO to  receive  a fair  and  reasonable  return  for its  expenses  and
obligations,  and a fair return for the lease of the premises and  equipment and
for providing the services contemplated hereunder,  that the agreed compensation
is not excessive.  The New PC acknowledges that the compensation  arrangement is
reasonable  under the  circumstances  noted herein and has executed an Affidavit
attesting  to this fact  which is  attached  hereto and  incorporated  herein as
Exhibit C. In consideration of the foregoing, the parties agree that the monthly
Management Fees payable to the MSO by the New PC for services  rendered pursuant
to this  Agreement  shall be reviewed and subject to  adjustment at the close of
each  year of the  Term of this  Agreement  based  upon  industry  standards  of
practice and the MSO's costs in performing the required services. If the parties
cannot agree within  thirty (30) days prior to the close of any such year on the
terms of any adjustment to the Management  Fees for the following year, then the
then existing  Management  Fees shall remain in effect.  The New PC specifically
agrees  that the MSO may defer  actual  receipt of its  Management  Fees  and/or
advance  monies for purposes of managing the New PC's cash flow, and the MSO may
repay itself such  advances or pay said deferred  Management  Fees when it deems
appropriate.

                                SECURITY INTEREST

MSO pursuant to this Agreement and any funds advanced by the MSO to or on behalf
of the New PC  pursuant  to this  Agreement  and for  the  faithful  and  timely
performance  of all the covenants  and  conditions to be performed by the New PC
under this Agreement, the New PC hereby pledges,  grants, bargains,  assigns and
transfers  to the MSO a security  interest,  pursuant to the Uniform  Commercial
Code of the State,  in and to all Practice  Revenue and accounts  receivable  of
patients of the New PC, together with all proceeds  thereof  (collectively,  the
"Collateral"),  and further agrees not to pledge, assign, transfer or convey any
of the Collateral or any proceeds  therefrom,  without the prior written consent
of the MSO,  except to affiliates of the MSO.  Concurrent  with the execution of
this Agreement,  the New PC shall execute a Security Agreement,  similar in form
and content as that attached hereto as Exhibit D and incorporated herein by this
reference in order that the MSO may perfect its interest in the Collateral.  The
New PC expressly agrees to execute any appropriate UCC-1 Financing Statement and

information  relating to the services and business  methods of OMEGA and the MSO
which it may  obtain  during the term of this  Agreement.  The New PC shall not,
either during the term of this  Agreement or at any time after the expiration or
sooner  termination  hereof,   disclose  to  anyone,  other  than  employees  or
independent  contractors  of OMEGA  and the MSO who use  OMEGA's  and the  MSO's
system in the course of the  performance of their duties,  any  confidential  or
proprietary information or trade secrets obtained by the New PC. The New PC also
agrees to place  any  persons  to whom said  information  is  disclosed  for the
purpose of  performance  under legal  obligation  to treat such  information  as
strictly confidential.

agrees not to  establish,  develop or open any  offices in  affiliation  with an
orthodontist  for the provision of orthodontic  services within a 15 mile radius
of the Orthodontic Offices, without the express written consent of the New PC.

                                    ARTICLE 9

for all liabilities in excess of the limits of such policies.  The MSO agrees to
negotiate for and cause premiums to be paid on behalf of the New PC with respect
to such insurance.  Premiums and deductibles with respect to such policies shall
not be MSO  Expenses.  The  New PC also  agrees  to name  the MSO and  OMEGA  as

as a result of the performance of orthodontic services or the performance of any
intentional  acts,  negligent  acts  or  omissions  by  the  New PC  and/or  its

                     AUTHORIZED AGENT AND POWERS OF ATTORNEY

      The New PC hereby  designates  the MSO (and its  designees) its authorized
agent and lawful  attorney-in-fact for purposes of depositing  payments,  paying
accounts  payables,  signing  checks,  negotiating  and  signing  contracts  for
services or goods,  securing loans or incurring obligations on behalf of the New
PC; 


                                       18
<PAGE>

provided,  however, that all contracts or fees set for services on behalf of the
New PC  will  be  subject  to  final  approval  and  acceptance  by the  New PC.
Additionally, the New PC hereby irrevocably appoints the MSO (and its designees)
its  authorized  agent and  lawful  attorney-in-fact  to  collect  all bills and
accounts  receivable  for  professional  fees,  charges  and other  amounts  and
authorizes the MSO through its designees to take possession of all checks, money
orders  and  similar  instruments  received  as  payment  of  receivables  to be
deposited into the New PC Account.  The New PC hereby  irrevocably  appoints the
MSO as the New PC's attorney-in-fact, with full power and authority in the place
and stead of the New PC, in the MSO's discretion,  to endorse in the name of the
New PC any checks,  payments,  notes,  insurance  payments and money orders,  to
withdraw  funds for payments of expenses,  including  Management  Fees and other
sums  payable to the MSO,  to open and close the New PC  Account  and other bank
accounts,  to take any action and to execute any other  instrument which the MSO
may deem necessary or advisable to accomplish the purposes hereof. The powers of
attorney granted herein are coupled with an interest and are irrevocable.  Third
parties and entities and persons not a party to this  Agreement  are entitled to
rely on the  foregoing  attorneys-in-fact  and an affidavit of the MSO attesting
thereto.  The acceptance of this appointment by the MSO shall not obligate it to
perform any duty or covenant  required to be performed by the New PC under or by
virtue of this Agreement.  Notwithstanding the foregoing powers of attorney, the
New PC shall at any time, on the request of the MSO, sign financing  statements,
security agreements or other agreements necessary or advisable to accomplish the
purpose of this  Agreement.  Upon the New PC's  failure  to sign said  financing
statements,  security  agreements or other agreements,  the MSO is authorized as
the agent of the New PC to sign any such instruments.  The New PC may review all
deposits and expenses upon request.

                                   ARTICLE 12
                       INDEPENDENT CONTRACTOR RELATIONSHIP

      Neither  the New PC nor its  employees  shall  have any claim  under  this
Agreement or otherwise against the MSO for worker's  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 the New PC. Since  neither the New PC nor its  employees  are
employees  of the MSO,  the MSO  shall  not  withhold  on  behalf  of the New PC
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 the New PC.

                                     ARTICLE  13
                                    MISCELLANEOUS

      13.1 Access to Records.  From and after any termination,  each party shall
provide the other party with  reasonable  access to books and records then owned
by it to permit  such  requesting  party to satisfy  reporting  and  contractual
obligations which may be required of it.

      13.2 Patient Records. Upon termination of this Agreement, the New PC shall
retain all patient  dental  records  maintained  by the New PC or the MSO in the
name of the New PC. During the term of this Agreement,  and thereafter,  the New
PC or its designee shall have reasonable  access during normal business 


                                       19
<PAGE>

hours to the New PC's and the MSO's  records,  including,  but not  limited  to,
records  of  collections,  expenses  and  disbursements  as  kept  by the MSO in
performing the MSO's obligations  under this Agreement,  and the New PC may copy
any or all such records.

      13.3 The New PC's Control Over the Orthodontic  Practice.  Notwithstanding
the authority  granted to the MSO herein,  the MSO and the New PC agree that the
New PC,  personally or through Dr.  Schneekluth or any of its  Orthodontists (if
any) and other Practice  Providers,  shall have complete control and supervision
over the professional aspects of the New PC's practice, as well as the provision
of all professional services,  including, without limitation, the selection of a
course of treatment for a patient,  the  procedures or materials to be used as a
part of such  course  of  treatment,  and the  manner  in which  such  course of
treatment is carried out by the New PC. The New PC shall have sole  authority to
direct the business,  professional,  and ethical  aspects of the New PC. The MSO
shall have no  authority,  directly or  indirectly,  to  perform,  and shall not
perform, any orthodontic  function,  or to influence or otherwise interfere with
the exercise of the New PC's professional judgment. The MSO may, however, advise
the  New  PC as to the  relationship  between  its  performance  of  orthodontic
functions and the overall administrative and business functioning of the New PC.

                           ALTERNATIVE DISPUTE RESOLUTION

      14.1 Alternative Dispute Resolution.

      (a) If a dispute  arises  under this  Agreement  which  cannot be resolved
informally  by the  parties,  any party may invoke the  procedures  set forth in
Exhibit E hereto and the parties agree to use these procedures, except paragraph
(b) of this Section 14.1, prior to any party pursuing other available  remedies.
The parties  will meet and attempt in good faith to resolve any  controversy  or
claim arising out of or relating to this Agreement.

      (b) Notwithstanding anything in this Section 14.1 to the contrary:

            (i)  Nothing  in this  Section  14.1 shall  preclude  any party from
      seeking a preliminary injunction or other provisional relief, either prior
      to or  during  the  proceeding  provided  for in this  section,  if in its
      judgment  such  action  is  necessary  to avoid  irreparable  damage or to
      preserve the status quo.

            (ii) The  parties  shall  accept  as  correct,  final,  binding  and
      conclusive the  determination by the outside  accountants then employed by
      the MSO as to the  calculation of any and all Management  Fees owed by the
      New PC to the MSO hereunder,  and such determination  shall not be subject
      to the  provisions  of  this  Section  14.1.  Disputes  as to  the  proper
      interpretation  of the  provisions of this  Agreement  which  describe how
      those  amounts  are to be  calculated,  however,  shall be  subject to the
      provisions of this Section 14.1.

            (iii) Any  determination by either party not to renew this Agreement
      in accordance with the terms and provisions of this Agreement shall not be
      subject to the provisions for dispute resolution in this Section 14.1.

      14.2  Waiver of Jury.  With  respect to any  dispute  arising  under or in
connection  with this  Agreement  or any  related  agreement,  as to which legal
action  nevertheless  occurs, each party hereby irrevocably waives all rights it
may have to demand a jury trial.  This waiver is  knowingly,  intentionally  and
voluntarily  made by the  parties  and each  party  acknowledges  that no person
acting  on behalf of the  other  party  has made any  representation  of fact to
induce this  waiver of trial by jury or in any way  modified  or  nullified  its
effect.  The parties each further  acknowledge  that it has been represented (or
has had the  opportunity to be represented) in the signing of this Agreement and
in the making of this waiver by independent  legal counsel,  selected of its own
free will,  and that it has had the  opportunity  to discuss  this  waiver  with
counsel.  Each party further  acknowledges  that it has read and understands the
meaning and ramifications of this waiver provision.

                                   ARTICLE 15
                               GENERAL PROVISIONS

      15.1 Notices.  Any notice to be given pursuant to this Agreement  shall be
deemed  effective if given  personally,  or by  telephone,  telegram,  telecopy,
facsimile  or other  electronic  transmission,  or by  letter to an  officer  or
administrator  of OMEGA,  the MSO or the New PC,  as the case may be.  Notice in
person,  or by telephone,  telegram or electronic  transmission  shall be deemed

time in writing.

      Attn: Robert Schulhof


or other such  addresses  as may be furnished by the MSO to the New PC from time
to time in writing.

      15.2 Confidentiality.  No party hereto shall disseminate or release to any
third party any information  regarding any provision of this  Agreement,  or any
financial information regarding the other parties (past, present or future) that
was obtained in the course of the negotiation of this Agreement or in the course
of


                                       21
<PAGE>

the performance of this Agreement, without the other party's or parties' (as the
case may be) written approval;  provided, however, the foregoing shall not apply
to information  which is required to be disclosed by Law,  including  federal or
state securities laws, or pursuant to court order.

      15.3 Contract Modifications for Prospective Legal Events. In the event any
state or  federal  Laws,  now  existing  or  enacted  or  promulgated  after the
effective  date of this  Agreement,  are  interpreted  by judicial  decision,  a
regulatory  agency  or legal  counsel  for both  parties  in such a manner as to
indicate that the structure of this  Agreement may be in violation of such Laws,
the New PC and the MSO shall amend this  Agreement as necessary.  To the maximum
extent possible,  any such amendment shall preserve the underlying  economic and
financial arrangements between the New PC and the MSO.

      15.4  Remedies  Cumulative.  No  remedy  set  forth in this  Agreement  or
otherwise conferred upon or reserved to any party shall be considered  exclusive
of any other  remedy  available  to any party,  but the same shall be  distinct,
separate  and  cumulative  and may be  exercised  from  time to time as often as
occasion may arise or as may be deemed expedient.

      15.5 No Obligation to Third Parties. None of the obligations and duties of
the MSO or the New PC under this Agreement  shall in any way or in any manner be
deemed to create  any  obligation  of the MSO or of the New PC to, or any rights
in, any person or entity not a party to this  Agreement  other than OMEGA  which
shall be deemed a party for limited purposes as set forth in this Agreement.

      15.6 Entire Agreement. This Agreement including the Schedules and Exhibits
hereto,  together  with the Stock  Put/Call  Option  and  Successor  Designation
Agreement of even date herewith and the Employment  Agreement(s)  (including the
related  non-competition  agreements  or  covenants),   constitutes  the  entire
agreement between the parties concerning this subject matter, and supersedes all
prior and contemporaneous agreements,  representations and understandings of the
parties  concerning  the  contents  hereof.  No  supplement,   modification,  or
amendment to this Agreement  shall be binding unless  executed in writing by all
of the parties hereto,  except as otherwise provided herein. No waiver of any of
the provisions of this  Agreement  shall be deemed to constitute a waiver of any
other provision, whether similar or not similar, nor shall any waiver constitute
a continuing  waiver.  No waiver shall be binding unless  executed in writing by
the party making the waiver.

      15.7  Assignment.  The  rights and the  duties of the  parties  under this
Agreement may not be assigned or transferred  without the prior written  consent
of the non-assigning  party,  which consent shall not be unreasonably  withheld;
provided,  however,  that the MSO shall be  permitted  to assign  its rights and
obligations  hereunder without the consent of the New PC to any person,  firm or
corporation  controlled by the MSO,  controlling the MSO or under common control
with the MSO.

      15.8  Attorneys'  Fees.  If any  mediation or  arbitration  or other legal
action or  proceeding  is  brought  to enforce  this  Agreement,  because of any
alleged  breach  hereof,  or for a  declaration  of any rights  and  obligations
hereunder,  the  prevailing  party in such mediation or  arbitration,  action or
proceeding  shall be entitled to recover its costs incurred  therein,  including
reasonable  attorneys'  fees, in addition to any other relief to which it may be
entitled,  all as determined  and awarded by the parties in such mediation or by
the arbitrator or court as 


                                       22
<PAGE>

part of its judgment or decision therein, as the case may be.

      15.9 Governing  Law. This Agreement  shall be governed by and construed in
accordance with the laws of the State.  The parties  acknowledge that the MSO is
not  authorized or qualified to engage in any activity which may be construed or
deemed to constitute  the practice of dentistry or  orthodontics.  To the extent
any act or service  required of the MSO in this Agreement should be construed or
deemed,  by any  governmental  authority,  agency  or  court to  constitute  the
practice of dentistry or orthodontics, the performance of said act or service by

                                   SCHEDULE 3

                         COMPENSATION - MANAGEMENT FEES

      The MSO and the New PC have  agreed  that  upon  receipt  of the  Practice
Revenues each month, the compensation shall be paid to the MSO and the New PC as
follows:

      1. First, the MSO Expenses shall be paid, until paid in full.

      2. Second, to the extent that there are Practice Revenues  remaining after
payment of the MSO Expenses, a monthly management fee of $3,333.33 shall be paid
to the MSO. Any portion of the management fee which is not paid shall accrue.

      3. The  balance,  if any, of  Practice  Revenues  received  for the month,
remaining  after  payment  of  items 1 and 2 shall  be  considered  profit,  and
distributed as follows:

            (a)  First to the New PC,  up to a monthly  maximum  of  twenty-five
      percent (25%) of Practice Revenue collected for such month.

            (b) Any balance  remaining after the payment of 3(a),  shall be paid
      to the MSO,  up to an monthly  maximum  amount of the  difference  between
      fifteen  percent (15%) of Practice  Revenue  collected for such month less
      $3,333.33.

      At the end of each twelve (12) month period  during the Term the MSO shall
provide the New PC with an unaudited  internal  accounting  of the MSO Expenses,
prepared in accordance with the accrual method of accounting If the MSO Expenses
as  reflected  in such  accounting  as having been paid by the MSO are less than
sixty (60%) percent of the Practice Revenues for such twelve month period, fifty
(50%) percent of such difference shall be returned by the MSO to the New PC as a
profit incentive rebate (the "Rebate").  If the Agreement to which this Schedule
3 is attached is terminated or expires,  the foregoing  Management Fees shall be
payable to the MSO based on all  Practice  Revenue  collected  as of the date of
termination or expiration.

      Payment  to the MSO  shall be made in  monthly  installments  based on the
Practice Revenues realized by the MSO for services rendered  hereunder.  The MSO
shall  distribute the proceeds from the New PC Account and allocate the proceeds
between the MSO and the New PC as described  above, on or before the 15th day of
the succeeding  month.  In the event the 15th day falls on a weekend or holiday,
then said  distribution  shall be made on the next  business  day.  The  parties
hereto may agree to handle such matters in a different manner.

      For  purposes  of this  Agreement,  "Practice  Revenues"  shall mean gross
collections  of all  revenues  generated  by or on behalf of the New PC (whether
through subsidiaries or affiliates), including, but not limited to, all fees and
charges collected as a result of professional  orthodontic services furnished to
patients by the New PC and for any other  goods or services  sold or provided to
such patients.



                                       27
<PAGE>

      Notwithstanding  3(a) above, each month during the term of this Agreement,
the New PC shall be entitled  to a draw of the  greater of the  amounts  payable
under 3(a), or $7,500.  If the Practice Revenues are insufficient to support the
draw amount,  the  difference  shall be paid by the MSO. The draw amount and the
actual  compensation due the New PC under this Schedule 3 shall be reconciled at
the end of each year.

AFFIDAVIT


      I, Clark E. Schneekluth, D.D.S., declare:

      I am an  orthodontist,  duly  licensed  in the State of  California  and I
practice through a professional  corporation under the name  ______________ (the
"New PC").

      I have had substantial  experience in the practice of the Orthodontics and
in managing and operating an orthodontic office.

      In  the  course  of  operating   orthodontic   offices,  I  have  acquired
significant  knowledge as to the  overhead  costs  incurred  and gross  receipts
generated by similar types of orthodontic offices.  Further, I am fully aware of
the non-orthodontic, operational, accounting, billing, financing, management and
personnel requirements of an orthodontic office and the cost factors involved in
providing  such  management,   personnel,  accounting,  billing,  financing  and
operation.

      I  have  thoroughly   reviewed  the  Management  Services  Agreement  (the
"Agreement"),  which is effective as of ________________,  1997, between the New
PC and Omega  Orthodontics of Huntington  Beach, Inc. (the "MSO") concerning the
duties,  responsibilities and obligations  undertaken by the MSO in managing and
operating all non-orthodontic  aspects of the Orthodontic Office as contemplated
by the Agreement.

      I  have  reviewed  the  prior  operating   financial   statements  of  the
orthodontic office located at 5112 Warner Avenue,  Suite 104,  Huntington Beach,
California 92649 and an operating budget and estimated income of the orthodontic
office,  which, in my opinion,  can reasonably be expected from the operation of
said office.

      In my  opinion,  based upon my  experience,  the  Management  Fees of ____
Percent (___%) of "Practice  Revenues" to be charged by the MSO as  contemplated
by the Agreement,  will afford it a reasonable but not excessive  return for its
services rendered and obligations incurred. In addition, the New PC ____ Percent
( %) of  "Practice  Revenues"  retained by the New PC, will  provide  reasonable
earnings for the performance of orthodontic services.

      I declare under  penalty of perjury that the  foregoing  statement is true
and correct to the best of my knowledge and belief.

      Executed at                               , ________ this day of , 1997.

collateral  security for the payment of the monthly  Management Fees owed to the
MSO pursuant to the Agreement and any funds  advanced by the MSO to or on behalf
of the  New PC  pursuant  to the  Agreement  and  for the  faithful  and  timely
performance  of all the covenants  and  conditions to be performed by the New PC
under  the  Agreement  (collectively,  the  "Obligations")  the New PC agreed to
pledge,  grant,  bargain,  assign and  transfer to the MSO a security  interest,
pursuant to the Uniform  Commercial  Code of the State,  in and to all  Practice
Revenue and the accounts receivable of patients of the New PC, together with all
proceeds thereof (collectively, the "Collateral");

      WHEREAS,  the New PC is obligated as a condition to the MSO's  performance
under the Agreement to execute and deliver this Security Agreement;

      NOW, THEREFORE, in consideration of the foregoing and of the covenants and
agreements hereinafter set forth, the parties hereto agree as follows:

      1. Grant of Security Interest.  As and for collateral security for payment
by the New PC of the  Obligations  and any and all  amounts  payable  under this
Security Agreement (collectively,  the "Secured Obligations"), the New PC hereby
pledges, grants,  bargains,  assigns and transfers to the MSO, and grants to the
MSO a security interest in, the Collateral.  Dr. Schneekluth shall cause the New
PC to perform fully and on a timely basis all of the New PC's obligations  under
this Security  Agreement.  The MSO may at its option file a financing  statement
(Form UCC-1) in order to perfect its security interest hereunder.

      2. Representations and Warranties.  The New PC represents and warrants all
of the accounts  receivable  constituting a portion of the Collateral of the New
PC pledged to the MSO are and will be validly created obligations of each of the
obligors who incurred same for services actually rendered in the ordinary course
of business of the New PC. Further,  the New PC represents and warrants that the
Collateral is not subject to any lien, pledge,  charge,  encumbrance or security
interest or right or option on the part of any third person.

      3. Release of Security Interest. Upon the termination of the Agreement and
payment in full of the accrued  Management Fees thereunder and any and all other
Secured Obligations,  the MSO shall release its security interest hereunder, and
will deliver to the New PC any property forming part of the Collateral delivered
to the MSO and then held by the MSO hereunder.

      4.  Realization  of  Collateral.  The MSO shall have,  with respect to the
Collateral,  the rights and  


                                       35
<PAGE>

obligations of a secured party under the Uniform  Commercial  Code as adopted in
the state of  California  (the  "State").  Such rights  shall  include,  without
limitation, the following:

     A. The right,  upon default,  to have the Collateral,  or any part thereof,
transferred to its own name or to the name of its nominee;

     B. The  right,  upon  default,  to sell,  assign or  deliver as much of the
Collateral  as is  reasonably  necessary  to repay  the  defaulted  indebtedness
(together with expenses  attendant upon such sale and  repayment),  at public or
private  sale,  as the MSO may  elect,  either  for cash or on  credit,  without
assumption  of any  credit  risk and  without  demand or  advertisement  (unless
otherwise required by law).

     C.  The New PC  hereby  irrevocably  authorizes  the MSO to sign  and  file
financing  statements naming the New PC as the debtor and the MSO as the secured
party, at any time with respect to any Collateral,  without the signature of the
New  PC.  The  New PC  hereby  irrevocably  appoints  the  MSO as the  New  PC's
attorney-in-fact,  with full  authority in the place and stead of the New PC and
in the name of the New PC,  from time to time in the MSO's  discretion,  to take
any action and to execute any  instrument  which the MSO may deem  necessary  or
advisable to accomplish the purposes hereof. The attorney-in-fact granted herein
is coupled with an interest and is  irrevocable.  Third parties and entities and
persons  not a party to this  Security  Agreement  are  entitled to rely on this
attorney-in-fact  and an affidavit of the MSO attesting thereto.  The acceptance
of this  appointment  by the MSO shall not  obligate  it to perform  any duty or
covenant  required  to be  performed  by the New PC  under or by  virtue  of the
Collateral. Notwithstanding the foregoing power of attorney, the New PC shall at
any  time  on the  request  of the  MSO,  sign  Financing  Statements,  security
agreements or other agreements with respect to any Collateral. Upon the New PC's
failure  to  sign  said  Financing  Statements,  security  agreements  or  other
agreements,  the MSO is  authorized  as the agent of the New PC to sign any such
instruments.  Upon the  request of the MSO,  the New PC agrees to pay all filing
fees and to  reimburse  the MSO on demand for all costs and expenses of any kind
(including,  without  limitation,  legal fees) incurred in any way in connection
with the Collateral.

      5.  Purchase  of  Collateral.  At any such  private or public  sale of the
Collateral  or  part  thereof,  the  MSO may  purchase  and pay for the  same by
cancellation of such portion of the Obligations, equal to the purchase price and
free of any  right  of  redemption  on the part of the New PC.  the MSO  agrees,
however,  that the New PC shall  have all  rights,  including  rights of notice,
provided by the  Uniform  Commercial  Code as adopted in the State.  In any case
where notice is required,  five days' notice shall be deemed reasonable  notice.
In the event of any sale  hereunder,  the MSO shall  apply the  proceeds  in the
order set forth  below in  Paragraph  6 hereof.  the MSO may have  resort to the
Collateral or any portion thereof with no requirements on the part of the MSO to
proceed first against any other person or property.

      6. Application of Collateral.  Proceeds from the sale of the Collateral or
any part thereof shall be applied by the MSO in the following order:

     A. To the payment of the costs and expenses of  collection  incurred by the

expenses, liabilities and costs incurred by the MSO in connection therewith;

                                       36

     B. To the payment of the whole  amount  then owing and unpaid for  advances
and/or Management Fees;

     C. To the payment in full of all other  Obligations of the New PC under the
Agreement; and

     D. To the payment to the New PC of any  surplus  then  remaining  from such
proceeds.

      7. Extension of Agreement.  No renewal or extension of the  Agreement,  no
release  or  surrender  of  any  Collateral  given  as  security  in  connection
therewith,  and no delay in  enforcement  thereof or in exercising  any right or
power with respect  thereto or hereunder shall affect the rights of the MSO with
respect to the Collateral or any part thereof.

      8. Notices.  Any notice to be given  pursuant to this  Agreement  shall be
deemed  effective  the same day when  such  notice  is given  personally,  or by
telegram,  or  electronic  transmission  to the  President  of the party to whom
notice is being given. Notice by mail shall be deemed effective three days after

                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A.    Method of Invoking ADR Procedures

      1. These procedures may be invoked by any party to an agreement which
incorporates these procedures by giving written notice to the other of the
dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such

an arbitrator, unless the


                                       41

parties and the mediator otherwise agree in writing.

      10. The mediator, if a lawyer, may freely express views to the parties on

mediation within the period provided in Part A above, the parties shall submit
the matter to binding arbitration in Boston, Massachusetts before a qualified
sole arbitrator in accordance with the then current CPR Rules for
Non-Administered Arbitration of Business Disputes. If the party initially
raising the dispute to be resolved is New PC or Dr. Schneekluth, the arbitration
shall be held in Boston, Massachusetts, and if the party initially raising the

Huntington Beach, California. The sole arbitrator shall be agreed upon by the
parties within twenty (20) days after either party elects to submit any issue to
arbitration or, failing that, shall be selected by CPR. A qualified arbitrator
is one who is familiar with the principal subject matter of the issues to be
arbitrated such as by way of example, healthcare services industry matters,
management consulting services generally or business law/corporate matters
generally. Judgment upon the award rendered by the arbitrator may be entered in
any court having jurisdiction. The arbitrator shall not have the authority to
award multiple, punitive or consequential damages under any circumstances.

impairs the New PC's or Dr. Schmisseur's ability to practice orthodontics.

     (c) For purposes hereof,  "Retirement" of Dr. Schmisseur shall occur on the
date when Dr. Schmisseur voluntarily withdraws from the practice of orthodontics
at whatever age or for  whatever  reason and notifies the New PC that he desires

MSO's approval of a qualified successor  orthodontist  reasonably  acceptable to

     6. Successor  Designation  Option  Exercise.  Except as otherwise  provided

<PAGE>

qualifications and suitability of the Designated Successor to conduct or perform
professional  services on behalf of the New PC.  Upon the MSO's  exercise of the
Successor  Designation  Option,  Dr.  Schmisseur shall execute a Non-Competition
Agreement in the form attached hereto as Exhibit C.

     8. Right of First Refusal and Sale of Stock. If Dr.  Schmisseur  desires to
sell any of the Capital Stock to another orthodontist (a "Purchaser"),  he shall
first give notice to the MSO of his intent to sell such Capital  Stock  ("Notice
of Sale"),  giving to the MSO such information as shall be reasonably  requested
by it to  ascertain  the  qualifications  and  suitability  of the  Purchaser to
conduct  or to  perform  professional  services  on behalf of the New PC and the
terms and  conditions of such proposed  sale to the  Purchaser.  Upon receipt of
such Notice, the Successor  Designation Option of the MSO with respect to all of
the Capital  Stock shall  become  exercisable  for a period of three (3) months,
provided however, that the exercise price per share and terms of purchase of the
Capital Stock shall be no less favorable to Dr.  Schmisseur than those set forth
in the  Notice of Sale.  In the event the  Successor  Designation  Option is not
exercised  during  such  three (3) month  period,  Dr.  Schmisseur  may sell the
Capital Stock to the Purchaser, with the consent of the MSO, which consent shall
not be  unreasonably  withheld,  upon the terms and  conditions set forth in the
Notice of Sale, provided however, that such sale shall be conditioned:  (i) upon
the  Purchaser  joining  in this  Agreement  and  entering  into  an  employment
agreement  with  the  New PC on  such  terms  and  conditions  as may be no more
favorable to the Purchaser  than those  applicable to Dr.  Schmisseur,  and (ii)
upon Dr. Schmisseur  executing a Non-Competition  Agreement in the form attached
hereto as Exhibit C.

     9. Assignment of the Successor Designation Option The Successor Designation
Option may be  assigned  by the MSO or any  assignee of the MSO to OMEGA or to a
duly licensed orthodontist,  by a written assignment, signed by both the MSO and
the  assignee.  When the context so requires in this  Agreement,  the term "MSO"
shall be deemed to refer to an assignee  holding an  assignment of the Successor
Designation Option with respect to such Capital Stock, and the terms "party" and
"parties" shall be deemed to include that assignee.

     10. Purchase Price of the Capital Stock.  (a) The purchase price ("Purchase
Price")  due and  payable  by the  Designated  Successor  upon  exercise  of the
Successor  Designation Option shall be an amount equal to the product of (a) the
aggregate net amount received by the New PC pursuant to Article 6 and Schedule 3
of the  Management  Services  Agreement  for the  twelve  (12)  calendar  months
immediately  preceding  the month in which the  Successor  Designation  Exercise
Notice is  delivered to Dr.  Schmisseur  (or his  successor  or  representative)
multiplied by (b) a fraction,  the numerator of which is the number of shares of
the Capital  Stock to be  purchased  and the  denominator  of which is the total
number of shares of the Capital Stock outstanding at the time of such purchase.

     (b) Payment of Purchase  Price.  The  Purchase  Price upon  exercise of the
Successor Designation Option shall be paid by the Designated Successor executing
a full recourse, negotiable promissory note, secured by the Capital Stock of Dr.
Schmisseur.  The note shall be for a term of five years,  with interest  payable
quarterly in arrears at the mid-term Applicable Federal Rate

                                      -6-

with monthly compounding  published by the Internal Revenue Service from time to
time in accordance with Section 1274(d) of the Internal Revenue Code of 1986, as
amended (the "Code") or any successor  provision of the Code,  provided however,
that the  Designated  Successor  shall be  permitted  to prepay such note at any
time.  Principal shall be payable in five equal annual  installments  commencing
six months after the closing date.

     (c) Purchase From Dr. Schmisseur's Estate.

          (i) Notwithstanding any other provision of this or any other Agreement
     between the parties, a Designated  Successor shall be obligated to purchase
     all of Dr. Schmisseur's Capital Stock upon his death. Upon the death of Dr.
     Schmisseur  and  receipt  of notice  of a  Successor  Designation  Exercise
     Notice, Dr. Schmisseur's personal representative shall apply for and obtain
     any  necessary   court  approval  or   confirmation  of  the  sale  of  Dr.
     Schmisseur's  shares of  Capital  Stock  pursuant  to this  Agreement.  The
     representative of the estate of Dr. Schmisseur and the Designated Successor
     shall  complete  such sale as soon after the date of death as  practicable,
     but no later than 180 days after such event.

          (ii) The  death  of Dr.  Schmisseur's  spouse,  if any,  shall  not be
     considered the death of Dr. Schmisseur for purposes of this Agreement.

          (iii) The estate of Dr.  Schmisseur  shall  bear,  and hold the New PC
     harmless from, all costs and expenses  incurred as a result of securing any
     court orders, court decrees,  court approvals or inheritance tax clearances
     required  to  enable  the  estate  of Dr.  Schmisseur  to  transfer  to the
     Designated Successor full legal and equitable tax-free title to the Capital
     Stock of Dr. Schmisseur.

     (d) Other Purchases. Except for purchases of Capital Stock upon exercise of
the Successor  Designation  Option pursuant to Section 5(a)(i) hereof, all other
purchases of Capital Stock  pursuant to such Option shall close thirty (30) days
after the date of any Successor Designation Exercise Notice ("Closing"),  unless
extended by the parties.

     11. Insurance.

     (a) In order to  insure  the  MSO's  interest  in the  Management  Services
Agreement  and under this  Agreement,  Dr.  Schmisseur  hereby  consents  to the
acquisition and maintenance in force of a disability insurance policy and a life
insurance policy on Dr. Schmisseur  ("Insurance  Policies").  The life insurance
policy may be in an aggregate face amount of up to three times Dr.  Schmisseur's
income,  as  shown on the W-2 Form  prepared  by the New PC for the most  recent
calendar  year.  Dr.  Schmisseur  agrees,  at the  election  of the MSO, to take
whatever  actions  are  necessary  to  facilitate  the  acquisition  of any such
Insurance Policy by the MSO.

     (b)  The  Insurance  Policies  shall  name  the New PC as  sole  owner  and
beneficiary of such policies.

     (c) As long as the Insurance Policies provided for herein are in full force
and effect,  the MSO shall pay all  premiums  falling  due on all such  policies
issued to it subject to this Agreement.

     (d) No insurance company that has issued or shall issue an Insurance Policy

                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A. Method of Invoking ADR Procedures

     1. These procedures may be invoked by any party to an agreement which
incorporates these procedures by giving written notice to the other of the
dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties, each acting through its representative, shall meet at a
mutually acceptable time and place within five business days after the
non-disputing party designates its representative to the other. At that meeting,
the parties shall attempt in good faith to negotiate a resolution of the
dispute, or failing that, to agree on a method for resolving the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer period of time as the parties may mutually agree, the parties have not
succeeded in negotiating a resolution of the claim or dispute or agreeing on a
dispute resolution mechanism, they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

     4. The parties will jointly appoint a mutually acceptable mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above, then the parties shall select a neutral third party from
the Center for Public Resources, New York, New York ("CPR") Panels of Neutrals,
with the assistance of CPR, unless the parties agree otherwise in finding a
mutually acceptable mediator.

     5. The New PC and the MSO shall each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR.

     6. The parties agree to participate in good faith in the mediation and
negotiations related thereto for a period of thirty (30) days from appointment
of a mediator by any of the parties or the CPR.


B. Mediation procedures

<PAGE>


     1. The mediator shall be neutral and impartial.

     2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.

          party.

     (b)  The mediator will decide when to hold joint meetings with the parties
          and when to hold separate meetings. There shall be no stenographic
          record of any meeting. Formal rules of evidence will not apply.

     (c)  The mediator may request that there be no direct communication between
          the parties or between their attorneys without the concurrence of the
          mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its officers and an attorney. Each party will have a representative fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator will not transmit information received from any party to
another party or any third person unless authorized to do so by the party
transmitting the information.

     6. The entire process is confidential. The parties and the mediator will
not disclose information regarding the process, including settlement terms, to
third persons, unless the parties otherwise agree. The process shall be treated
as a compromise negotiation for purposes of the Federal Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing administrative and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

     (a)  The mediator will be disqualified as a witness, consultant or expert
          in any pending or future investigation, action or proceeding relating
          to the subject matter of the mediation (including any investigation,
          action or proceeding which involves persons not party to this
          mediation); and

     (b)  The mediator and any documents and information in the mediator's
          possession will not be subpoenaed in any such investigation, action or


                                      -19-
<PAGE>


          proceeding, and all parties will oppose any effort to have the
          mediator and documents subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.

     10. The mediator, if a lawyer, may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons, (ii) if the mediator believes that a party
is not acting in good faith, or (iii) if the mediator concludes that further
mediation efforts would not be useful.

C. Binding Arbitration

     If the parties do not resolve the dispute through mediation within the
period provided in Part A above, the parties shall submit the matter to binding
arbitration before a qualified sole arbitrator in accordance with the then
current CPR Rules for Non-Administered Arbitration of Business Disputes. The
sole arbitrator shall be agreed upon by the parties within twenty (20) days
after either party elects to submit any issue to arbitration or, failing that,
shall be selected by CPR. A qualified arbitrator is one who is familiar with the
principal subject matter of the issues to be arbitrated such as by way of
example, healthcare services industry matters, management consulting services
generally or business law/corporate matters generally. Judgment upon the award
rendered by the arbitrator may be entered in any court having jurisdiction. The
arbitrator shall not have the authority to award multiple, punitive or
consequential damages under any circumstances. If the party initially raising
the dispute to be resolved is New PC or Dr. Schmisseur, the arbitration shall be
held in Boston, Massachusetts, and if the party initially raising the dispute to
be resolved is the MSO or OMEGA, the arbitration shall be held in Chicago,
Illinois. be held in Chicago, Illinois.

     applicable  Employment  Agreement with Dr. Saydyk contemplated  thereunder,
     and any  goodwill  and other  intangible  assets  set forth on the  Balance
     Sheet,   reflecting   amortization   or  depreciation  of  the  restrictive
     covenants, and any goodwill and other intangible assets; and

          (c) Assume all debt and all  contracts,  payables and leases which are
     obligations  of the MSO and which relate solely to the  performance  of its
     obligations  under the  Management  Services  Agreement  or the  properties
     subleased in respect of the Orthodontic Offices.

If the MSO desires to exercise its Put Option, the MSO shall give written notice
of such election to the New PC and Dr. Saydyk at least twenty (20) calendar days
prior to the date  specified  in such  notice as the date for the closing of the
Put  Option.  Any  exercise  of the Put  Option  by the MSO  shall be made by an

 thereof, to:


          (a) Sell to the New PC all of the  leasehold  improvements,  fixtures,
     furniture,   furnishings  and  equipment   comprising  or  located  at  the
     Orthodontic Offices,  including all replacements and additions thereto made
     by the  MSO  pursuant  to the  performance  of its  obligations  under  the
     Management Services Agreement and all other assets, including inventory and
     supplies  and  intangibles,  set  forth on the  Balance  Sheet  to  reflect
     operations  of the MSO in respect  of the  Orthodontic  Offices,  including
     depreciation,  amortization  and other  adjustments of such assets shown on
     such Balance Sheet; and

          (b)  Assign  to,  or  grant a  waiver  in favor  of,  the New PC,  the
     restrictive  covenants  provided  for in  Section  3.7  of  the  Management
     Services  Agreement and in the  applicable  Employment  Agreement  with Dr.
     Saydyk  contemplated  thereunder,  and any  goodwill  and other  intangible
     assets  set  forth  on  the  Balance  Sheet,   reflecting  amortization  or
     depreciation  of the  restrictive  covenants,  and any  goodwill  and other
     intangible assets; and

          (c)  Assign  to the New PC (which  it shall  assume)  all debt and all

     relate solely to the  performance of its  obligations  under the Management
     Services   Agreement  or  the  properties   subleased  in  respect  of  the
     Orthodontic Offices.

If the New PC desires to exercise its Call Option, the New PC shall give written
notice of such  election to the MSO at least twenty (20)  calendar days prior to
the date  specified  in such  notice  as the date  for the  closing  of the Call
Option.  Any  exercise  of the  Call  Option  by the New PC  shall be made by an
aggregate  payment to the MSO of an amount equal to the sum of (x) the amount of
cash paid to Dr. Saydyk under Section  2.1(b)(i) of the  Affiliation  Agreement,
plus (y) the original principal amount of the Purchase Note issued to Dr. Saydyk
under Section  2.1(b)(ii) of the  Affiliation  Agreement,  plus (z) the value of
that number of shares of Omega Common Stock issued to Dr.  Saydyk under  Section
2.1(b)(ii)  of  the  Affiliation  Agreement,  such  value  to be  determined  by
multiplying  such number of shares by the average of the last sales (or closing)
price for Omega's Common Stock on Nasdaq (or a national securities exchange) for
each of the sixty (60)  trading  days  immediately  preceding  the date the Call
Option Notice is delivered to the MSO (collectively, the "Call Price").

     4. Closing and Delivery. The closing ("Closing") of the exercise by the MSO
of the Put Option  under  Section 2 or of the exercise by the New PC of the Call
Option under  Section 3, as the case may be, shall be at the offices of Robinson
& Cole, One Boston Place, Boston,  Massachusetts 02108 on the date specified for
such  Closing in the written  notice of election to exercise  such Put Option or
Call  Option,  as the case may be,  or on such  other  date as the  parties  may
mutually  determine.  At the  Closing,  the New PC shall pay cash,  or, with the
consent of Dr. Saydyk, a combination of cash,  forgiveness of amounts due to Dr.
Saydyk under the  Purchase  Note and/or and return of the shares of Omega Common

                                      -3-
<PAGE>

hereof, pursuant to exercise by the New PC of the Call Option, as the case may
be. The New PC shall execute such documents as may be required by the MSO to
assume the liabilities set forth in Section 2(c) or 3(c), as the case may be,
and shall use their respective best efforts to remove the MSO from any liability
with respect to such repurchased assets and with respect to any property leased
or subleased by the MSO. From and after any such Closing, each party shall
provide to the other parties reasonable access to books and records then owned
by it to permit such requesting party to satisfy reporting and contractual
obligations which may be required of it. In addition, following any such
Closing, the MSO or its designee shall have reasonable access during normal
business hours to the New PCs records, including patient records regarding
records of collections, expenses and disbursements as kept by the MSO in
performing its obligations under the Management Services Agreement, and the MSO
may copy any or all such records.

     5. Successor Designation Option.

     (a) Upon termination of the Management  Services Agreement by the MSO under
Section 10.2 thereof or upon  expiration of the Term of the Management  Services
Agreement  or upon the  happening of any of the  following  events (each of such
termination,  expiration or event being  hereinafter  referred to as a "Transfer
Event"),  the MSO shall have the option (the "Designated  Successor  Option") to

     this Section 5 below;

          (iii) if Dr. Saydyk  voluntarily  terminates  his  employment  without
     first  proposing and obtaining the MSO's  approval of a proposed  qualified
     successor  orthodontist  reasonably  acceptable to the MSO on behalf of the
     New PC;

          (iv) if Dr.  Saydyk acts in a criminally or grossly  negligent  manner
     with  respect  to the  performance  of  professional  orthodontic  services
     rendered or to be rendered on behalf of the New PC;

          (v) if Dr. Saydyk becomes hospitalized for alcohol or drug abuse;

     transferred voluntarily

                                      -4-
<PAGE>


     or by operation of law to any person who is a "disqualified person," as
     defined in the professional corporation statute of the Laws of the State;

          (ix) if Dr. Saydyk  voluntarily  files a petition under any bankruptcy

     the benefit of creditors;

          (x) if Dr.  Saydyk is  subjected  involuntarily  to such a petition or
     assignment, or any creditor or other persons obtains an attachment or other
     legal or  equitable  interest  in any  shares of the  Capital  Stock of Dr.
     Saydyk and such  involuntary  petition,  assignment  or  attachment  is not
     discharged within sixty (60) days after creation;

          (xi) if Dr. Saydyk is required to transfer any shares of Capital Stock

          (xii) if Dr.  Saydyk  retires  within the meaning of Paragraph  (c) of
     this Section 5; or

          (xiii) if Dr.  Saydyk  desires  to sell any of his  shares of  Capital
     Stock to another orthodontist as contemplated under Section 6 hereof.

     (b) For  purposes  hereof,  "permanent  disability"  means  either  (1) any
illness,  injury,  disease or condition  other than the "  Pre-Existing  Medical
Condition"  (as  defined  below),  whether  mental  or  physical,  which,  for a
continuous  period of thirty (30) days, (i) prevents Dr. Saydyk from  performing
his duties  competently  and  adequately,  as determined in accordance  with the
alternative dispute resolution  procedures in Section 18 and Schedule D, or (ii)
substantially  impairs  the  New  PC's  or  Dr.  Saydyk's  ability  to  practice
orthodontics; or (2) either or both of the Pre-Existing Medical Condition, which
for a continuous  period of three hundred and sixty five (365) days or more than
a total of five hundred  (500) days over the period of two calendar  years,  (i)
prevent Dr. Saydyk from practicing  orthodontics for the New PC for the "Average
Weekly Hours" (as defined below), or (ii) substantially  impairs the New PC's or
Dr.  Saydyk's  ability  to  practice  orthodontics.  As used in this  Agreement,
"Pre-Existing  Medical  Condition"  means  either  or both of Dr.  Saydyk's  two
pre-existing  medical  conditions  previously  disclosed to OMEGA,  and "Average
Weekly  Hours"  means a number  which is equal to: (a) the total number of hours
Dr. Saydyk  practiced  orthodontics  over the immediately  preceding one hundred
fifty-six  (156) weeks,  excluding  therefrom  those weeks where Dr.  Saydyk was
absent  from the  office for any  portion of the week for any reason  other than
vacations  and  holidays,  divided by the number of weeks Dr.  Saydyk  practiced
orthodontics and was not absent for such reasons.

     (c) For purposes hereof, "Retirement" of Dr. Saydyk shall occur on the date
when Dr.  Saydyk  voluntarily  withdraws  from the practice of  orthodontics  at
whatever age or for  whatever  reason and notifies the New PC that he desires to
be regarded as "Retired" and fails to have first proposed and obtained the MSO's
approval of a qualified successor orthodontist reasonably acceptable to the MSO.

     (d) For purposes hereof,  "Voluntary Termination" of Dr. Saydyk shall occur
on the  date  when  Dr.  Saydyk  voluntarily  withdraws  from  the  practice  of
orthodontics for whatever reason and


                                      -5-
<PAGE>


notifies the New PC that he desires to be regarded as  "Voluntarily  Terminated"
and fails to have first  proposed and obtained the MSO's approval of a qualified
successor orthodontist reasonably acceptable to the MSO.

     6. Successor  Designation Option Exercise.  Except as otherwise provided in
(b) below and  otherwise  herein,  upon  exercise of the  Successor  Designation
Option,  the  Designated  Successor  may purchase all or any part of the Capital
Stock. The failure of the MSO to exercise this Successor  Designation  Option as
to all of the  Capital  Stock at any one time shall not limit the MSO's right to
exercise the Successor  Designation Option with respect to any remaining Capital
Stock at any time during the term of this Agreement.  The Successor  Designation
Option shall also be exercisable by the MSO as provided in Section 8 below.

     (b) In the  event  that  the MSO is  entitled  to  exercise  the  Successor
Designation  Option solely due to the Section 5(b)(2),  in that the Pre-Existing
Medical  Condition  has for a continuous  period of three hundred and sixty five
(365)  days or more than a total of five  hundred  days  over the  period of two
calendar  years,   either  prevented  Dr.  Saydyk  from  performing  his  duties
competently and adequately as determined by the MSO, or  substantially  impaired
the New PC's or Dr.  Saydyk's  ability to  practice  orthodontics,  then in such
case, the  Designated  Successor may purchase fifty percent (50%) of the Capital
Stock.

     7. Exercise Notice. Any exercise of the Successor  Designation Option shall
be accompanied by a written notice (the "Successor Designation Exercise Notice")
to Dr. Saydyk (or his successor or representative), specifying the name, address
and  information  showing the  qualifications  and suitability of the Designated
Successor  to conduct or perform  professional  services on behalf of the New PC
and number of shares of Capital  Stock of Dr.  Saydyk as to which the  Successor
Designation Option is being exercised.  Upon the MSO's exercise of the Successor
Designation Option in respect of any event described in Section 5(a)(iii) or (x)
as to all of the shares of Capital Stock of Dr. Saydyk, Dr. Saydyk shall execute
a  Non-Competition  Agreement in the form attached  hereto as Exhibit C. The MSO
may, at any time,  cancel any Successor  Designation  Exercise Notice sent by it
hereunder.

     8. Right of First Refusal and Sale of Stock.  If Dr. Saydyk desires to sell
any of the Capital Stock to another orthodontist (a "Purchaser"), he shall first
give  notice to the MSO of his intent to sell such  Capital  Stock  ("Notice  of
Sale"),  giving to the MSO such information as shall be reasonably  requested by
it to ascertain the  qualifications  and suitability of the Purchaser to conduct
or to perform  professional  services  on behalf of the New PC and the terms and
conditions of such proposed sale to the Purchaser.  Upon receipt of such Notice,
the  Successor  Designation  Option of the MSO shall  become  exercisable  for a
period of three (3) months,  provided however, that the exercise price and terms
of purchase of the Capital  Stock shall be no less  favorable to Dr. Saydyk than
those set forth in the Notice of Sale.  In the event the  Successor  Designation
Option is not exercised during such three (3) month period,  Dr. Saydyk may sell
the Capital Stock to the  Purchaser,  with the consent of the MSO, which consent
shall not be unreasonably  withheld,  upon the terms and conditions set forth in
the Notice of Sale, provided however,  that such sale shall be conditioned:  (i)
upon the  Purchaser  joining in this  Agreement  and entering into an employment


                                      -6-
<PAGE>


agreement with the New PC on such terms and conditions as may be approved by the
MSO, and (ii) upon Dr. Saydyk executing a Non-Competition  Agreement in the form
attached hereto as Exhibit C.

     9. Assignment of the Successor Designation Option The Successor Designation
Option may be  assigned  by the MSO or any  assignee of the MSO to OMEGA or to a
duly licensed orthodontist,  by a written assignment, signed by both the MSO and
the assignee. When the context so
requires  in this  Agreement,  the term  "MSO"  shall be  deemed  to refer to an
assignee holding an assignment of the Successor  Designation Option with respect
to such Capital  Stock,  and the terms "party" and "parties"  shall be deemed to
include that assignee.

     10. Purchase Price of the Capital Stock.  (a) The purchase price ("Purchase
Price")  due and  payable  by the  Designated  Successor  upon  exercise  of the
Successor  Designation Option shall be an amount equal to the product of (a) the
aggregate net amount received by the New PC pursuant to Article 6 and Schedule 3
of the  Management  Services  Agreement  for the  twelve  (12)  calendar  months
immediately  preceding  the month in which the  Successor  Designation  Exercise
Notice  is  delivered  to  Dr.  Saydyk  (or  his  successor  or  representative)
multiplied by (b) a fraction,  the numerator of which is the number of shares of
the Capital  Stock to be  purchased  and the  denominator  of which is the total
number of shares of the Capital Stock outstanding at the time of such purchase.

     (b) Payment of Purchase  Price.  The  Purchase  Price upon  exercise of the
Successor Designation Option shall be paid by the Designated Successor executing
a nonrecourse,  negotiable  promissory note, secured by the Capital Stock of Dr.
Saydyk.  The  note  shall be for a term of five  years,  with  interest  payable
quarterly  in arrears  at the  mid-term  Applicable  Federal  Rate with  monthly
compounding  published  by the  Internal  Revenue  Service  from time to time in
accordance with Section 1274(d) of the Internal Revenue Code of 1986, as amended
(the "Code") or any successor provision of the Code, provided however,  that the
Designated  Successor  shall be  permitted  to  prepay  such  note at any  time.
Principal  shall be payable in five equal  annual  installments  commencing  six
months after the closing date.

     (c) Purchase From Dr. Saydyk's Estate.

          (i) Upon the death of Dr.  Saydyk and receipt of notice of a Successor
     Designation  Exercise Notice,  Dr. Saydyk's personal  representative  shall
     apply for and obtain any necessary  court approval or  confirmation  of the
     sale of Dr.  Saydyk's  shares of Capital Stock pursuant to this  Agreement.
     The representative of the estate of Dr. Saydyk and the Designated Successor
     shall  complete  such sale as soon after the date of death as  practicable,
     but no later than 180 days after such event.

          (ii) The death of Dr. Saydyk's spouse, if any, shall not be considered
     the death of Dr. Saydyk for purposes of this Agreement.

          (iii)  The  estate  of Dr.  Saydyk  shall  bear,  and  hold the New PC
     harmless 


                                      -7-
<PAGE>


     from, all costs and expenses incurred as a result of securing any court
     orders, court decrees, court approvals or inheritance tax clearances
     required to enable the estate of Dr. Saydyk to transfer to the Designated
     Successor full legal and equitable tax-free title to the Capital Stock of
     Dr. Saydyk.

     (b) Other Purchases. Except for purchases of Capital Stock upon exercise of
the Successor  Designation  Option pursuant to Section 5(a)(i) hereof, all other
purchases of Capital Stock  pursuant to such Option shall close thirty (30) days
after the date of any Successor Designation Exercise Notice ("Closing"),  unless
extended by the parties.

     11. Insurance.

     (a) In order to  insure  the  MSO's  interest  in the  Management  Services
Agreement  and  under  this  Agreement,   Dr.  Saydyk  hereby  consents  to  the
acquisition and maintenance in force of a disability insurance policy and a life
insurance policy on Dr. Saydyk ("Insurance Policies"). The life insurance policy
may be in an aggregate face amount of up to three times Dr. Saydyk's income,  as
shown on the W-2 Form prepared by the New PC for the most recent  calendar year.
Dr.  Saydyk  agrees,  at the election of the MSO, to take  whatever  actions are
necessary to facilitate the acquisition of any such Insurance Policy by the MSO.

     (b)  The  Insurance  Policies  shall  name  the New PC as  sole  owner  and
beneficiary of such policies.

     (c) As long as the Insurance Policies provided for herein are in full force
and effect,  the MSO shall pay all  premiums  falling  due on all such  policies
issued to it subject to this Agreement.

     (d) No insurance company that has issued or shall issue an Insurance Policy
or  Policies to the MSO as  permitted  under this  Agreement  shall be under any
obligation  with respect to the  performance of the terms and conditions of this
Agreement.  Any such company  shall be bound only by the terms of the  Insurance
Policy or Policies which it has issued or shall  hereafter  issue and shall have
no liability except as set forth in its policies.

     12.  Representations.  The New PC and Dr. Saydyk each represent and warrant
to the MSO and OMEGA that as of the day and year first above  written and during
the term of this  Agreement,  Exhibit A is a true and  complete  listing  of the
Capital Stock, as revised from time to time pursuant to this Agreement.

     13. Restriction on Transfer.

     (a) Except to the extent and in the manner  provided in this  Agreement  or
with the  express  prior  written  consent  of the MSO which may be  granted  or
withheld  in its  absolute  discretion,  Dr.  Saydyk  shall  not  sell,  assign,
transfer, pledge or otherwise dispose (including by gift or otherwise) of any of
his shares of the Capital Stock.

     (b)  Issuance of Stock;  Change in  Ownership;  Mergers and  Consolidation.
Without the prior  written  consent of the MSO, Dr.  Saydyk shall not permit the
New PC to, and the New PC shall not,  during the term of this  Agreement,  issue

the foregoing without the prior written consent of the MSO.

     14. Delivery of Stock Power.  Upon execution of this Agreement,  Dr. Saydyk
shall  execute  and  deliver  to the MSO,  a  sufficient  number of  assignments
separate  from  certificates,  endorsed  in blank to cover all of the Stock (the
"Stock  Power")  held of  record  or  beneficially  owned  by Dr.  Saydyk.  Upon
execution  of  this  Agreement,   Dr.  Saydyk  shall  deliver  to  the  MSO  all
certificates  heretofore issued  representing all of the shares of Capital Stock
held of record or beneficially owned by Dr. Saydyk.  Each such certificate shall
have affixed to the back of the certificate a legend substantially as follows:

     "The  rights  of any  holder of any share  evidenced  by this  certificate,
     including  the  right to  dispose  of the  securities  represented  by this
     certificate  or any interest  therein,  are subject to and  restricted by a
     certain Stock Put/Call Option and Successor Designation Agreement,  dated ,
     1997, among the New PC, the holder hereof and the MSO and OMEGA (as defined
     therein). The New PC will mail without charge to any holder of these shares
     a copy of such agreement within five (5) days of receipt by the New PC of a
     written request therefor."

     Upon any exercise of the Successor  Designation  Option by the MSO, the MSO
(and/or the  Designated  Successor)  shall be  authorized  to complete the Stock
Powers,  attach  them to the  certificates  and tender the same to the  transfer
agent for the New PC for  reissuance  in the name of the  Designated  Successor.
Upon  any  termination  of this  Agreement  without  exercise  of the  Successor
Designation Option, the MSO shall return all such Stock Powers to Dr. Saydyk.

     15.  Confidentiality.  The parties shall use all good faith efforts to keep
the  contents  of this  Agreement  and all  other  aspects  of the  negotiations
preceding execution of this Agreement confidential.  Unless required by law, the
New PC, Dr.  Saydyk,  and the MSO and OMEGA shall not  disclose  the contents of
this  Agreement or the  negotiations  leading to this Agreement to third parties
without the prior  written  consent of the other  parties.  The MSO shall ensure
that  all  of  the   assignees   likewise   comply  with  the   obligations   of
confidentiality  imposed by this Section,  except that the MSO and the assignees
may disclose the contents of such to the extent  required by law or otherwise to
their  respective  agents,  representatives,  contractors,  and employees to the
extent necessary to exercise their respective rights or perform their respective
obligations hereunder.

     16. Term. The term of this Agreement  shall commence as of the day and year
first above written and shall  terminate upon the  termination of the Management
Services Agreement or the exercise (and consummation of the transaction provided

     18.1 General.  (a) If a dispute arises under this Agreement which cannot be
resolved  informally  by the parties,  any party may invoke the  procedures  set
forth in Exhibit D hereto and the parties agree to use these procedures,  except

                                    EXHIBIT D

                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A. Method of Invoking ADR Procedures

     1.  These  procedures  may be invoked  by any party to an  agreement  which
incorporates  these  procedures  by  giving  written  notice to the other of the
dispute  and   designating  a  person  with   decision-making   authority   (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required  to respond to the  disputing  party's  notice
within five (5) business days by designating in writing its own  representative.
A party may choose  more than one person to  represent  it. If a party  appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties,  each acting  through its  representative,  shall meet at a
mutually  acceptable  time and place  within  five (5)  business  days after the
non-disputing party designates its representative to the other. At that meeting,
the  parties  shall  attempt  in good faith to  negotiate  a  resolution  of the
dispute,  or  failing  that,  to agree on a method  for  resolving  the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer  period of time as the parties may mutually  agree,  the parties have not
succeeded in  negotiating  a resolution of the claim or dispute or agreeing on a
dispute  resolution  mechanism,  they shall  submit the dispute to  mediation in
accordance with the procedures set forth herein.

     4. The  parties  will  jointly  appoint a mutually  acceptable  mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above,  then the parties  shall select a neutral third party from
the Center for Public Resources,  New York, New York ("CPR") Panels of Neutrals,
with the  assistance  of CPR,  unless the parties  agree  otherwise in finding a
mutually acceptable mediator.

     5. The New PC and the MSO shall  each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR.

     6. The parties  agree to  participate  in good faith in the  mediation  and
negotiations  related thereto for a period of thirty (30) days from  appointment
of a mediator by any of the parties or the CPR.

     7. Notwithstanding anything to the contrary in this Exhibit D, if a dispute
arises  concerning  Dr.  Saydyk  ability to perform his duties  competently  and
adequately, the parties agree to  


                                      -18-
<PAGE>


utilize the  procedures  set forth in this  Exhibit D to resolve such dispute by
mediation  within  thirty (30) days after the day written  notice is given under
number one above that such a dispute  exists.  In order to meet the thirty  (30)
day deadline,  the parties agree that the timeframes in numbers 1, 2 and 4 above
shall be reduced to two (2) days,  the timeframe in number 3 shall be reduced to
five (5) days,  and that the  timeframe  in number 6 above  shall be  reduced to
twelve (12) days.

B. Mediation procedures

     1. The mediator shall be neutral and impartial.

     2. The mediator shall control the procedural aspects of the mediation.  The
parties will cooperate fully with the mediator.

     (a)  The  mediator  is free to meet and  communicate  separately  with each
          party.

     (b)  The mediator will decide when to hold joint  meetings with the parties
          and when to hold  separate  meetings.  There shall be no  stenographic
          record of any meeting. Formal rules of evidence will not apply.

     (c)  The mediator may request that there be no direct communication between
          the parties or between their attorneys  without the concurrence of the
          mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its  officers and an attorney.  Each party will have a  representative  fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator  will not transmit  information  received from any party to
another  party or any  third  person  unless  authorized  to do so by the  party
transmitting the information.

     6. The entire  process is  confidential.  The parties and the mediator will
not disclose information  regarding the process,  including settlement terms, to
third persons,  unless the parties otherwise agree. The process shall be treated
as a compromise  negotiation  for purposes of the Federal  Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing  administrative  and/or  judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,


                                      -19-
<PAGE>

     (a)  The mediator will be disqualified  as a witness,  consultant or expert
          in any pending or future investigation,  action or proceeding relating
          to the subject matter of the mediation  (including any  investigation,
          action  or  proceeding  which  involves  persons  not  party  to  this
          mediation); and

     (b)  The mediator  and any  documents  and  information  in the  mediator's
          possession will not be subpoenaed in any such investigation, action or
          proceeding,  and all  parties  will  oppose  any  effort  to have  the
          mediator and documents subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.

     10. The mediator,  if a lawyer,  may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator  shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written  notice to the parties
(i) for overriding personal reasons,  (ii) if the mediator believes that a party
is not acting in good faith,  or (iii) if the  mediator  concludes  that further
mediation efforts would not be useful.

C. Binding Arbitration

     If the  parties do not resolve the  dispute  through  mediation  within the
period provided in Part A above,  the parties shall submit the matter to binding
arbitration  in Boston,  Massachusetts  before a qualified  sole  arbitrator  in
accordance with the then current CPR Rules for  Non-Administered  Arbitration of
Business Disputes.  If the party initially raising the dispute to be resolved is
New PC or Dr. Saydyk,  the arbitration  shall be held in Boston,  Massachusetts,
and if the party  initially  raising  the  dispute to be  resolved is the MSO or
OMEGA, the arbitration  shall be held in Denver,  Colorado.  The sole arbitrator
shall be agreed upon by the parties  within  twenty (20) days after either party
elects to submit any issue to arbitration or, failing that, shall be selected by
CPR. A qualified  arbitrator is one who is familiar  with the principal  subject
matter of the  issues to be  arbitrated  such as by way of  example,  healthcare
services industry matters,  management consulting services generally or business
law/corporate  matters  generally.  Judgment  upon  the  award  rendered  by the
arbitrator may be entered in any court having jurisdiction. The arbitrator shall
not have the  authority to award  multiple,  punitive or  consequential  damages
under any circumstances.


                                      -20-

<PAGE>

     Notwithstanding anything to the contrary in this Section C of Exhibit D, if
a  dispute  arises  concerning  Dr.  Saydyk's  ability  to  perform  his  duties
competently and  adequately,  and the parties are unable to resolve such dispute
by  mediation,  the parties  agree to utilize the  procedures  set forth in this
Section C of Exhibit D to resolve such dispute by  arbitration,  and to agree to
the sole arbitrator within ten (10) days after the end of thirty (30) day period
provided in Number 7 of Part A above,  and to proceed  with the  arbitration  as
quickly as possible so that a judgment may be awarded within  seventy-five  (75)
days of the date  written  notice  of the  dispute  is given  under  number 1 of
Section A.

                                                                   Exhibit 10.10

days prior to the date  specified  in such notice as the date for the closing of

Feldman Section 2.1(b)(ii) of the Affiliation  Agreement,  plus (z) the value of
that number of shares of Omega Common Stock issued to Dr.  Feldman under Section

each of the sixty (60)  trading  days  immediately  preceding  the date the Call
Option Notice is delivered to the MSO (collectively, the "Call Price").

Robinson  & Cole,  One Boston  Place,  Boston,  Massachusetts  02108 on the date
specified  for such Closing in the written  notice of election to exercise  such
Put  Option or Call  Option,  as the case may be, or on such  other  date as the
parties may mutually  determine.  At the Closing,  the New PC, at its  election,
shall pay  cash,  or a  combination  of cash and  return of the  shares of Omega
Common Stock received by Dr. Feldman under Section 2.1(b)(ii) of the Affiliation
Agreement,  such  shares  to be  valued  as  provided  for in  Section 3 hereof,
pursuant to exercise by the New PC of the Call  Option,  as the case may be. The
New PC and Dr. Feldman shall

execute such  documents as may be required by the MSO to assume the  liabilities
set  forth in  Section  2(c) or 3(c),  as the case may be,  and  shall use their
respective  best  efforts to remove the MSO from any  liability  with respect to
such repurchased  assets and with respect to any property leased or subleased by
the MSO. From and after any such Closing,  each party shall provide to the other
parties  reasonable  access to books and records then owned by it to permit such
requesting party to satisfy  reporting and contractual  obligations which may be
required of it. In addition, following any such Closing, the MSO or its designee
shall  have  reasonable  access  during  normal  business  hours  to the New PCs
records,  including patient records  regarding records of collections,  expenses
and  disbursements  as kept by the MSO in performing its  obligations  under the

     rendered or to be rendered on behalf of the New PC;

          (v) if Dr. Feldman becomes hospitalized for alcohol or drug abuse;

          (vi) if Dr. Feldman is convicted of a felony;

          (x) if Dr.  Feldman is subjected  involuntarily  to such a petition or
     assignment, or any creditor or other persons obtains an attachment or other
     legal or  equitable  interest  in any  shares of the  Capital  Stock of Dr.
     Feldman and such  involuntary  petition,  assignment  or  attachment is not
     discharged within sixty (60) days after creation;

          (xi) if Dr.  Feldman is  required  to  transfer  any shares of Capital

approval of a qualified successor orthodontist reasonably acceptable to the MSO.

     6. Successor  Designation  Option  Exercise.  Except as otherwise  provided
herein,  upon  exercise of the  Successor  Designation  Option,  the  Designated
Successor may purchase all or any part of the Capital Stock.  The failure of the
MSO to exercise this Successor Designation Option as to all of the Capital Stock
at any one time  shall  not  limit the MSO's  right to  exercise  the  Successor
Designation  Option  with  respect to any  remaining  Capital  Stock at any time
during the term of this Agreement.  The Successor  Designation Option shall also
be exercisable by the MSO as provided in Section 8 below.

     7. Exercise Notice. Any exercise of the Successor  Designation Option shall
be accompanied by a written notice (the "Successor Designation Exercise Notice")
to Dr.  Feldman  (or his  successor  or  representative),  specifying  the name,
address  and  information  showing the  qualifications  and  suitability  of the
Designated  Successor to conduct or perform  professional  services on behalf of
the New PC and number of shares of Capital Stock of Dr.  Feldman as to which the
Successor Designation Option is being exercised. Upon the MSO's exercise of the

                                      -5-
<PAGE>


Successor  Designation  Option in  respect  of any event  described  in  Section
5(a)(iii)  or (x) as to all of the  shares  of  Capital  Stock  of Dr.  Feldman,

notice to the MSO of his intent to sell such Capital  Stock  ("Notice of Sale"),
giving to the MSO such  information  as shall be  reasonably  requested by it to
ascertain the  qualifications  and suitability of the Purchaser to conduct or to
perform  professional  services  on  behalf  of the  New PC and  the  terms  and
conditions of such proposed sale to the Purchaser.  Upon receipt of such Notice,
the  Successor  Designation  Option of the MSO shall  become  exercisable  for a
period of three (3) months,  provided however, that the exercise price and terms
of purchase of the Capital Stock shall be no less  favorable to Dr. Feldman than
those set forth in the Notice of Sale.  In the event the  Successor  Designation
Option is not exercised during such three (3) month period, Dr. Feldman may sell
the Capital Stock to the  Purchaser,  with the consent of the MSO, which consent
shall not be unreasonably  withheld,  upon the terms and conditions set forth in
the Notice of Sale, provided however,  that such sale shall be conditioned:  (i)
upon the  Purchaser  joining in this  Agreement  and entering into an employment
agreement with the New PC on such terms and conditions as may be approved by the
MSO, and (ii) upon Dr. Feldman executing a Non-Competition Agreement in the form
attached hereto as Exhibit C.

     9. Assignment of the Successor Designation Option The Successor Designation
Option may be  assigned  by the MSO or any  assignee of the MSO to OMEGA or to a
duly licensed orthodontist,  by a written assignment, signed by both the MSO and
the  assignee.  When the context so requires in this  Agreement,  the term "MSO"
shall be deemed to refer to an assignee  holding an  assignment of the Successor
Designation Option with respect to such Capital Stock, and the terms "party" and
"parties" shall be deemed to include

the twelve (12)  calendar  months  immediately  preceding the month in which the
Successor  Designation  Exercise  Notice is  delivered  to Dr.  Feldman  (or his
successor or  representative)  multiplied  by (b) a fraction,  the  numerator of
which is the  number of  shares of the  Capital  Stock to be  purchased  and the
denominator  of which  is the  total  number  of  shares  of the  Capital  Stock
outstanding at the time of such purchase.

     (b) Payment of Purchase  Price.  The  Purchase  Price upon  exercise of the
Successor Designation Option shall be paid by the Designated Successor executing

provision of the Code, provided however,  that the Designated Successor shall be
permitted  to prepay such note at any time.  Principal  shall be payable in five
equal annual installments commencing six months after the closing date.

     (c) Purchase From Dr. Feldman's Estate.

          (i) Upon the death of Dr. Feldman and receipt of notice of a Successor
     Designation  Exercise Notice, Dr. Feldman's personal  representative  shall
     apply for and obtain any necessary  court approval or  confirmation  of the
     sale of Dr.  Feldman's  shares of Capital Stock pursuant to this Agreement.
     The  representative  of  the  estate  of Dr.  Feldman  and  the  Designated
     Successor  shall  complete  such  sale as soon  after  the date of death as
     practicable, but no later than 180 days after such event.

          (ii)  The  death  of  Dr.  Feldman's  spouse,  if  any,  shall  not be
     considered the death of Dr. Feldman for purposes of this Agreement.

          (iii)  The  estate  of Dr.  Feldman  shall  bear,  and hold the New PC
     harmless from, all costs and expenses  incurred as a result of securing any
     court orders, court decrees,  court approvals or inheritance tax clearances
     required to enable the estate of Dr.  Feldman to transfer to the Designated
     Successor  full legal and equitable  tax-free title to the Capital Stock of
     Dr. Feldman.

Agreement  and  under  this  Agreement,  Dr.  Feldman  hereby  consents  to  the

policy may be in an  aggregate  face amount of up to three  times Dr.  Feldman's
income,  as  shown on the W-2 Form  prepared  by the New PC for the most  recent
calendar year. Dr. Feldman agrees,  at the election of the MSO, to take whatever
actions are necessary to facilitate the acquisition of any such Insurance Policy
by the MSO.

     (b)  The  Insurance  Policies  shall  name  the New PC as  sole  owner  and
beneficiary of such policies.

                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A.Method of Invoking ADR Procedures

     1. These procedures may be invoked by any party to an agreement which
incorporates these procedures by giving written notice to the other of the
dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties, each acting through its representative, shall meet at a
mutually acceptable time and place within five business days after the
non-disputing party designates its representative to the other. At that meeting,
the parties shall attempt in good faith to negotiate a resolution of the
dispute, or failing that, to agree on a method for resolving the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer period of time as the parties may mutually agree, the parties have not
succeeded in negotiating a resolution of the claim or dispute or agreeing on a
dispute resolution mechanism, they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

     4. The parties will jointly appoint a mutually acceptable mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above, then the parties shall select a neutral third party from
the Center for Public Resources, New York, New York ("CPR") Panels of Neutrals
or the American Arbitration Association ("AAA"), with the assistance of CPR or
AAA, unless the parties agree otherwise in finding a mutually acceptable
mediator.

     5. The New PC and the MSO shall each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR or AAA.

     6. The parties agree to participate in good faith in the mediation and
negotiations related thereto for a period of thirty (30) days from appointment
of a mediator by any of the parties or the CPR or AAA.


B. Mediation procedures


                                      -17-
<PAGE>


     1. The mediator shall be neutral and impartial.

     2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.


     (a)  The  mediator  is free to meet and  communicate  separately  with each
          party.

     (b)  The mediator will decide when to hold joint meetings with the parties
          and when to hold separate meetings. There shall be no stenographic
          record of any meeting. Formal rules of evidence will not apply.

     (c)  The mediator may request that there be no direct communication between
          the parties or between their attorneys without the concurrence of the
          mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its officers and an attorney. Each party will have a representative fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator will not transmit information received from any party to
another party or any third person unless authorized to do so by the party
transmitting the information.

     6. The entire process is confidential. The parties and the mediator will
not disclose information regarding the process, including settlement terms, to
third persons, unless the parties otherwise agree. The process shall be treated
as a compromise negotiation for purposes of the Federal Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing administrative and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

     (a)  The mediator will be disqualified as a witness, consultant or expert
          in any pending or future investigation, action or proceeding relating
          to the subject matter of the mediation (including any investigation,
          action or proceeding which involves persons not party to this
          mediation); and

     (b)  The mediator and any documents and information in the mediator's
          possession will not be subpoenaed in any such investigation, action or

                                      -18-
<PAGE>


          proceeding,  and all  parties  will  oppose  any  effort  to have  the
          mediator and documents subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.

     10. The mediator, if a lawyer, may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons, (ii) if the mediator believes that a party
is not acting in good faith, or (iii) if the mediator concludes that further
mediation efforts would not be useful.

C. Binding Arbitration

     If the parties do not resolve the dispute through mediation within the
period provided in Part A above, the parties shall submit the matter to binding
arbitration in Boston, Massachusetts before a qualified sole arbitrator in
accordance with the then current CPR Rules for Non-Administered Arbitration of
Business Disputes or comparable AAA rules. The arbitration shall be held in
Woodland Hills, California. The sole arbitrator shall be agreed upon by the
parties within twenty (20) days after either party elects to submit any issue to
arbitration or, failing that, shall be selected by CPR or AAA A qualified
arbitrator is one who is familiar with the principal subject matter of the
issues to be arbitrated such as by way of example, healthcare services industry
matters, management consulting services generally or business law/corporate
matters generally. Judgment upon the award rendered by the arbitrator may be
entered in any court having jurisdiction. The arbitrator shall not have the
authority to award multiple, punitive or consequential damages under any
circumstances.

          (b) Purchase,  by obtaining an assignment from the MSO, at book value,

If the MSO desires to exercise its Put Option, the MSO shall give written notice
of such  election to the New PC and Dr.  Zapalac at least  twenty (20)  calendar
days prior to the date  specified  in such notice as the date for the closing of
the Put  Option.  Any  exercise of the Put Option by the MSO shall be made by an

Section 2 (collectively, the "Put Price").

     Employment  Agreement with Dr.  Zapalac  contemplated  thereunder,  and any

     Services   Agreement  or  the  properties   subleased  in  respect  of  the
     Orthodontic Offices.

If the New PC desires to exercise its Call Option, the New PC shall give written
notice of such  election to the MSO at least twenty (20)  calendar days prior to
the date  specified  in such  notice  as the date  for the  closing  of the Call
Option.  Any  exercise  of the  Call  Option  by the New PC  shall be made by an
aggregate  payment to the MSO of an amount equal to the sum of (x) the amount of

plus (y) an amount equal to the value of the option granted to Dr. Zapalac under
Section 2.1(b)(ii) of the Affiliation Agreement (the "Option"). The Option shall
be value at an amount  equal to the  difference,  if any,  between  the  Average
Market  Value Price (as defined  below in this Section 3) of OMEGA Stock and IPO
Price (as defined in Section 2.1(b)(i) of the Affiliation Agreement), multiplied
by the number of shares of Omega Common Stock granted in the Option. The Average
Market Value Price shall be  determined by averaging the last sales (or closing)
price for Omega's Common Stock on Nasdaq (or a national securities exchange) for
each of the sixty (60)  trading  days  immediately  preceding  the date the Call
Option Notice is delivered to the MSO (collectively, the "Call Price").

     4. Closing and Delivery. The closing ("Closing") of the exercise by the MSO

& Cole, One Boston Place, Boston,  Massachusetts 02108 on the date specified for
such  Closing in the written  notice of election to exercise  such Put Option or
Call  Option,  as the case may be,  or on such  other  date as the  parties  may
mutually determine.  At the Closing, the New PC, at its election shall pay cash,
or a combination  of cash and a  cancellation  of the Option,  such Option to be
valued as provided for in Section 3 hereof, for the repurchased assets,  whether
the Put Price pursuant to exercise by the MSO

                                      -3-

of the Put Option or the Call Price  pursuant  to  exercise by the New PC of the
Call Option,  as the case may be. The New PC and Dr.  Zapalac shall execute such
documents as may be required by the MSO to assume the  liabilities  set forth in
Section 2(c) or 3(c),  as the case may be, and shall use their  respective  best
efforts to remove the MSO from any  liability  with respect to such  repurchased
assets and with respect to any property leased or subleased by the MSO. From and
after any such Closing, each party shall provide to the other parties reasonable
access to books and records then owned by it to permit such requesting  party to
satisfy  reporting and contractual  obligations  which may be required of it. In
addition,  following  any  such  Closing,  the MSO or its  designee  shall  have
reasonable access during normal business hours to the New PCs records, including
patient records regarding records of collections,  expenses and disbursements as
kept by the MSO in performing  its  obligations  under the  Management  Services
Agreement, and the MSO may copy any or all such records.

     5. Successor Designation Option.

     (a) Upon termination of the Management  Services Agreement by the MSO under
Section 10.2 thereof or upon  expiration of the Term of the Management  Services
Agreement  or upon the  happening of any of the  following  events (each of such
termination,  expiration or event being  hereinafter  referred to as a "Transfer
Event"),  the MSO shall have the option (the "Successor  Designation Option") to
designate a successor orthodontist or successor  orthodontists,  which person or
persons must be duly licensed  orthodontists in the State or otherwise permitted
by law to be a  shareholder  in a  professional  corporation  in the  State,  to

then held by Dr. Zapalac:

          (i) the death of Dr. Zapalac;

          (iii) if Dr. Zapalac  voluntarily  terminates  his employment  without
     first  proposing and obtaining the MSO's  approval of a proposed  qualified
     successor  orthodontist  reasonably  acceptable to the MSO on behalf of the
     New PC;

          (iv) if Dr. Zapalac acts in a criminally or grossly  negligent  manner
     with  respect  to the  performance  of  professional  orthodontic  services
     rendered or to be rendered on behalf of the New PC;

          (v) if Dr. Zapalac becomes hospitalized for alcohol or drug abuse;

          (vi) if Dr. Zapalac is convicted of a felony;

          (vii) if Dr.  Zapalac loses his license or is otherwise  determined to

     by the applicable dental or other

                                      -4-
<PAGE>

     comparable regulatory board of the State;

          (viii)  if Dr.  Zapalac's  shares  of  Capital  Stock are or are to be
     transferred  voluntarily  or by  operation  of law to any  person  who is a
     "disqualified  person," as defined in the professional  corporation statute
     of the Laws of the State;

          (ix) if Dr. Zapalac  voluntarily files a petition under any bankruptcy
     or insolvency law or a petition for the appointment of a receiver, or makes
     an assignment for the benefit of creditors;

          (x) if Dr.  Zapalac is subjected  involuntarily  to such a petition or
     assignment, or any creditor or other persons obtains an attachment or other
     legal or  equitable  interest  in any  shares of the  Capital  Stock of Dr.
     Zapalac and such  involuntary  petition,  assignment  or  attachment is not
     discharged within sixty (60) days after creation;

          (xi) if Dr.  Zapalac is  required  to  transfer  any shares of Capital

     law;

          (xii) if Dr.  Zapalac  retires  within the meaning of Paragraph (c) of

     Stock to another orthodontist as contemplated under Section 6 hereof.

     (b) For purposes hereof,  "permanent disability" means any illness, injury,
disease or condition, whether mental or physical, which, for a continuous period
of thirty  (30) days,  (i)  prevents  Dr.  Zapalac  from  performing  his duties
competently  and  adequately  as  determined  by the MSO, or (ii)  substantially
impairs the New PC's or Dr. Zapalac's ability to practice orthodontics.

     (c) For purposes  hereof,  "Retirement"  of Dr.  Zapalac shall occur on the
date when Dr. Zapalac voluntarily withdraws from the practice of orthodontics at
whatever age or for  whatever  reason and notifies the New PC that he desires to
be regarded as "Retired" and fails to have first proposed and obtained the MSO's
approval of a qualified successor orthodontist reasonably acceptable to the MSO.

     6. Successor  Designation  Option  Exercise.  Except as otherwise  provided
herein,  upon  exercise of the  Successor  Designation  Option,  the  Designated
Successor may purchase all or any part of the Capital Stock.  The failure of the
MSO to exercise this Successor Designation Option as to all of the Capital Stock
at any one time  shall  not  limit the MSO's  right to  exercise  the  Successor
Designation  Option  with  respect to any  remaining  Capital  Stock at any time
during the term of this Agreement.  The Successor  Designation Option shall also
be exercisable by the MSO as provided in Section 8 below.

     7. Exercise Notice. Any exercise of the Successor  Designation Option shall
be accompanied by a written notice (the "Successor Designation Exercise Notice")
to Dr. Zapalac (or

                                      -5-
<PAGE>

his successor or  representative),  specifying the name, address and information
showing the  qualifications  and  suitability  of the  Designated  Successor  to
conduct or perform  professional  services on behalf of the New PC and number of
shares of Capital  Stock of Dr.  Zapalac as to which the  Successor  Designation
Option is being exercised.  Upon the MSO's exercise of the Successor Designation
Option in respect of any event  described in Section  5(a)(iii) or (x) as to all
of the shares of Capital  Stock of Dr.  Zapalac,  Dr.  Zapalac  shall  execute a
Non-Competition Agreement in the form attached hereto as Exhibit C. The MSO may,
at any  time,  cancel  any  Successor  Designation  Exercise  Notice  sent by it
hereunder.

     8. Right of First Refusal and Sale of Stock. If Dr. Zapalac desires to sell
any of the Capital Stock to another orthodontist (a "Purchaser"), he shall first
give  notice to the MSO of his intent to sell such  Capital  Stock  ("Notice  of
Sale"),  giving to the MSO such information as shall be reasonably  requested by
it to ascertain the  qualifications  and suitability of the Purchaser to conduct
or to perform  professional  services  on behalf of the New PC and the terms and
conditions of such proposed sale to the Purchaser.  Upon receipt of such Notice,
the  Successor  Designation  Option of the MSO shall  become  exercisable  for a
period of three (3) months,  provided however, that the exercise price and terms
of purchase of the Capital Stock shall be no less  favorable to Dr. Zapalac than
those set forth in the Notice of Sale.  In the event the  Successor  Designation
Option is not exercised during such three (3) month period, Dr. Zapalac may sell
the Capital Stock to the  Purchaser,  with the consent of the MSO, which consent
shall not be unreasonably  withheld,  upon the terms and conditions set forth in
the Notice of Sale, provided however,  that such sale shall be conditioned:  (i)
upon the  Purchaser  joining in this  Agreement  and entering into an employment
agreement with the New PC on such terms and conditions as may be approved by the
MSO, and (ii) upon Dr. Zapalac executing a Non-Competition Agreement in the form
attached hereto as Exhibit C.

     9. Assignment of the Successor Designation Option The Successor Designation
Option may be  assigned  by the MSO or any  assignee of the MSO to OMEGA or to a
duly licensed orthodontist,  by a written assignment, signed by both the MSO and
the  assignee.  When the context so requires in this  Agreement,  the term "MSO"
shall be deemed to refer to an assignee  holding an  assignment of the Successor
Designation Option with respect to such Capital Stock, and the terms "party" and
"parties" shall be deemed to include that assignee.

     10. Purchase Price of the Capital Stock.  (a) The purchase price ("Purchase
Price")  due and  payable  by the  Designated  Successor  upon  exercise  of the
Successor  Designation Option shall be an amount equal to the product of (a) the
aggregate net amount received by the New PC pursuant to Article 6 and Schedule 3
of the  Management  Services  Agreement  for the  twelve  (12)  calendar  months
immediately  preceding  the month in which the  Successor  Designation  Exercise
Notice  is  delivered  to Dr.  Zapalac  (or  his  successor  or  representative)
multiplied by (b) a fraction,  the numerator of which is the number of shares of
the Capital  Stock to be  purchased  and the  denominator  of which is the total
number of shares of the Capital Stock outstanding at the time of such purchase.

     (b) Payment of Purchase  Price.  The  Purchase  Price upon  exercise of the


                                      -6-
<PAGE>

Successor Designation Option shall be paid by the Designated Successor executing
a nonrecourse,  negotiable  promissory note, secured by the Capital Stock of Dr.
Zapalac.  The note  shall be for a term of five  years,  with  interest  payable
quarterly  in arrears  at the  mid-term  Applicable  Federal  Rate with  monthly
compounding  published  by the  Internal  Revenue  Service  from time to time in
accordance with Section 1274(d) of the Internal Revenue Code of 1986, as amended

Principal  shall be payable in five equal  annual  installments  commencing  six
months after the closing date.

     (c) Purchase From Dr. Zapalac's Estate.

     The  representative  of the  estate  of Dr.  Zapalac  shall  make  complete
     application for court approval on the date which is the later of forty-five
     days  after  Dr.  Zapalac's  death or twenty  days  after  such  Designated
     Successor is found.  The  representative  of the estate and the  Designated
     Successor shall diligently pursue completion of such sale as soon after the
     date of death as practicable.

          (ii)  The  death  of  Dr.  Zapalac's  spouse,  if  any,  shall  not be

     Successor full legal and equitable title, free of all inheritance and other
     transfer taxes, to the Capital Stock of Dr. Zapalac.

Agreement  and  under  this  Agreement,  Dr.  Zapalac  hereby  consents  to  the
acquisition and maintenance in force of a disability insurance policy and a life
insurance  policy on Dr.  Zapalac  ("Insurance  Policies").  The life  insurance
policy may be in an  aggregate  face amount of up to three  times Dr.  Zapalac's
income,  as  shown on the W-2 Form  prepared  by the New PC for the most  recent
calendar year. Dr. Zapalac agrees,  at the election of the MSO, to take whatever
actions are necessary to facilitate the acquisition of any such Insurance Policy
by the MSO.

or  Policies to the MSO as  permitted  under this  Agreement  shall be under any
obligation  with respect to the  performance of the terms and conditions of this
Agreement.  Any such company  shall be bound only by the terms of the  Insurance
Policy or Policies which it has issued or shall  hereafter  issue and shall have
no liability except as set forth in its policies.

     12. Representations.  The New PC and Dr. Zapalac each represent and warrant
to the MSO and OMEGA that as of the day and year first above  written and during
the term of this  Agreement,  Exhibit A is a true and  complete  listing  of the
Capital Stock, as revised from time to time pursuant to this Agreement.

     13. Restriction on Transfer.

or otherwise reorganize with or into any other corporation,  partnership, trade,
business,  or the like;  amend or otherwise modify its articles of incorporation
or bylaws;  dissolve;  or enter into any agreement  with any person to do any of
the foregoing without the prior written consent of the MSO.

Zapalac shall execute and deliver to the MSO, a sufficient number of assignments
separate from certificates,  endorsed in blank to cover all of the Capital Stock
(the "Stock Power") held of record or beneficially  owned by Dr.  Zapalac.  Upon
execution  of  this  Agreement,  Dr.  Zapalac  shall  deliver  to  the  MSO  all
certificates  heretofore issued  representing all of the shares of Capital Stock
held of record or beneficially owned by Dr. Zapalac. Each such certificate shall
have affixed to the back of the certificate a legend substantially as follows:

     "The  rights  of any  holder of any share  evidenced  by this  certificate,
     including  the  right to  dispose  of the  securities  represented  by this
     certificate or any interest therein, are subject to

                                      -8-

     and restricted by a certain Stock Put/Call Option and Successor Designation
     Agreement, dated, 1997, among the New PC, the holder hereof and the MSO and
     OMEGA (as  defined  therein).  The New PC will mail  without  charge to any
     holder of these  shares a copy of such  agreement  within  five (5) days of
     receipt by the New PC of a written request therefor."

     Upon any exercise of the Successor  Designation  Option by the MSO, the MSO
(and/or the  Designated  Successor)  shall be  authorized  to complete the Stock
Powers,  attach  them to the  certificates  and tender the same to the  transfer
agent for the New PC for  reissuance  in the name of the  Designated  Successor.
Upon  any  termination  of this  Agreement  without  exercise  of the  Successor
Designation Option, the MSO shall return all such Stock Powers to Dr. Zapalac.

     15.  Confidentiality.  The parties shall use all good faith efforts to keep
the  contents  of this  Agreement  and all  other  aspects  of the  negotiations
preceding execution of this Agreement confidential.  Unless required by law, the
New PC, Dr.  Zapalac,  and the MSO and OMEGA shall not  disclose the contents of
this  Agreement or the  negotiations  leading to this Agreement to third parties
without the prior  written  consent of the other  parties.  The MSO shall ensure
that  all  of  the   assignees   likewise   comply  with  the   obligations   of
confidentiality  imposed by this Section,  except that the MSO and the assignees
may disclose the contents of such to the extent  required by law or otherwise to
their  respective  agents,  representatives,  contractors,  and employees to the
extent necessary to exercise their respective rights or perform their respective
obligations hereunder.

     16. Term. The term of this Agreement  shall commence as of the day and year
first above written and shall  terminate upon the  termination of the Management
Services Agreement or the exercise (and consummation of the transaction provided
for upon such  exercise)  of the Put Option,  the Call  Option or the  Successor
Designation  Option  as to all of the  Capital  Stock,  as the  case may be (the
"Term").

MSO) on the other hand are acting in the  capacity of the grantor and grantee of

neither  this  Agreement  nor the  rights and  duties of this  Agreement  may be

                                    EXHIBIT D


                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A.   Method of Invoking ADR Procedures

     1. These procedures may be invoked by any party to an agreement which
incorporates these procedures by giving written notice to the other of the
dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties, each acting through its representative, shall meet at a
mutually acceptable time and place within five business days after the
non-disputing party designates its representative to the other. At that meeting,
the parties shall attempt in good faith to negotiate a resolution of the
dispute, or failing that, to agree on a method for resolving the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer period of time as the parties may mutually agree, the parties have not
succeeded in negotiating a resolution of the claim or dispute or agreeing on a
dispute resolution mechanism, they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

     4. The parties will jointly appoint a mutually acceptable mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above, then the parties shall select a neutral third party from
either the Center for Public Resources, New York, New York ("CPR") Panels of
Neutrals, the American Arbitration Association ("AAA") or the Association of
Attorney Neutrals ("AAN"), with the assistance of such organization, unless the
parties agree otherwise in finding a mutually acceptable mediator.

     5. Acquisition shall bear 50% and the New PC and Dr. Zapalac shall bear 50%
of the fees and costs of the mediator and any fees and costs of CPR, AAA or AAN.

     6. The parties agree to participate in good faith in the mediation and
negotiations related thereto for a period of thirty (30) days from appointment
of a mediator by any of the parties or the CPR, AAA or AAN.


                                      -17-
<PAGE>

B.   Mediation procedures

     1. The mediator shall be neutral and impartial.

     2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.


     (a)  The mediator is free to meet and communicate separately with each
          party.

     (b)  The mediator will decide when to hold joint meetings with the parties
          and when to hold separate meetings. There shall be no stenographic
          record of any meeting. Formal rules of evidence will not apply.

     (c)  The mediator may request that there be no direct communication between
          the parties or between their attorneys without the concurrence of the
          mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its officers and an attorney. Each party will have a representative fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator will not transmit information received from any party to
another party or any third person unless authorized to do so by the party
transmitting the information.

     6. The entire process is confidential. The parties and the mediator will
not disclose information regarding the process, including settlement terms, to
third persons, unless the parties otherwise agree. The process shall be treated
as a compromise negotiation for purposes of the Federal Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing administrative and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

     (a)  The mediator will be disqualified as a witness, consultant or expert
          in any pending or future investigation, action or proceeding relating
          to the subject matter of the mediation (including any investigation,
          action or proceeding which involves persons not party to this
          mediation); and

     (b)  The mediator and any documents and information in the mediator's


                                      -18-
<PAGE>

          possession will not be subpoenaed in any such investigation, action or
          proceeding, and all parties will oppose any effort to have the
          mediator and documents subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.

     10. The mediator, if a lawyer, may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons, (ii) if the mediator believes that a party
is not acting in good faith, or (iii) if the mediator concludes that further
mediation efforts would not be useful.

C.   Binding Arbitration

     If the parties do not resolve the dispute through mediation within the
period provided in Part A above, the parties shall submit the matter to binding
arbitration before AAA, AAN or CPR, to a qualified sole arbitrator in accordance
with the then current CPR Rules for Non-Administered Arbitration of Business
Disputes or comparable AAA or AAN rules. The sole arbitrator shall be agreed
upon by the parties within twenty (20) days after either party elects to submit
any issue to arbitration or, failing that, shall be selected by the organization
to whom the parties selected for arbitration. A qualified arbitrator is one who
is familiar with the principal subject matter of the issues to be arbitrated
such as by way of example, healthcare services industry matters, management
consulting services generally or business law/corporate matters generally.
Judgment upon the award rendered by the arbitrator may be entered in any court
having jurisdiction. The arbitrator shall not have the authority to award
multiple, punitive or consequential damages under any circumstances. If the
party initially raising the dispute to be resolved is New PC or Dr. Zapalac, the
arbitration shall be held in Boston, Massachusetts, and if the party initially
raising the dispute to be resolved is the MSO or OMEGA, the arbitration shall be

approval of a qualified successor orthodontist reasonably acceptable to the MSO.

     6. Stock Designation Option Exercise.  Except as otherwise provided herein,
upon exercise of the Stock  Designation  Option,  the  Designated  Successor may
purchase  all or any  part  of the  Capital  Stock.  The  failure  of the MSO to
exercise this Stock Designation Option as to all of the Capital Stock at any one
time shall not limit the MSO's right to exercise  the Stock  Designation  Option
with respect to any remaining  Capital Stock at any time during the term of this
Agreement.  The Stock Designation Option shall also be exercisable by the MSO as
provided in Section 8 below.

     7. Exercise Notice.  Any exercise of the Stock Designation  Option shall be
accompanied by a written notice (the "Stock Designation Exercise Notice") to Dr.
Grove (or his successor or  representative),  specifying  the name,  address and
information  showing  the  qualifications  and  suitability  of  the  Designated
Successor  to conduct or perform  professional  services on behalf of the New PC
and  number  of  shares  of  Capital  Stock of Dr.  Grove as to which  the Stock
Designation  Option is being  exercised.  Upon the MSO's  exercise  of the Stock
Designation Option in respect of any event described in Section 5(a)(iii) or (x)
as to all of the shares


                                      -5-
<PAGE>

of  Capital  Stock of Dr.  Grove,  Dr.  Grove  shall  execute a  Non-Competition
Agreement  in the form  attached  hereto as Exhibit C. The MSO may, at any time,
cancel any Stock Designation Exercise Notice sent by it hereunder.

     8. Right of First  Refusal and Sale of Stock.  If Dr. Grove desires to sell
any of the Capital Stock to another orthodontist (a "Purchaser"), he shall first
give  notice to the MSO of his intent to sell such  Capital  Stock  ("Notice  of
Sale"),  giving to the MSO such information as shall be reasonably  requested by
it to ascertain the  qualifications  and suitability of the Purchaser to conduct
or to perform  professional  services  on behalf of the New PC and the terms and
conditions of such proposed sale to the Purchaser.  Upon receipt of such Notice,
the Stock Designation Option of the MSO shall become exercisable for a period of
three  (3)  months,  provided  however,  that the  exercise  price  and terms of
purchase of the Capital Stock shall be no less favorable to Dr. Grove than those
set forth in the Notice of Sale.  In the event the Stock  Designation  Option is
not exercised  during such three (3) month period,  Dr. Grove may sell the Stock
to the  Purchaser,  with the  consent  of the MSO,  which  consent  shall not be
unreasonably withheld,  upon the terms and conditions set forth in the Notice of
Sale,  provided  however,  that such  sale  shall be  conditioned:  (i) upon the
Purchaser  joining in this  Agreement and entering into an employment  agreement
with the New PC on such terms and  conditions as may be approved by the MSO, and
(ii) upon Dr. Grove executing a  Non-Competition  Agreement in the form attached
hereto as Exhibit C.

     9. Assignment of the Stock Designation  Option The Stock Designation Option
may be  assigned  by the MSO or any  assignee  of the MSO to  OMEGA or to a duly
licensed orthodontist,  by a written assignment,  signed by both the MSO and the
assignee.  When the context so requires in this Agreement,  the term "MSO" shall
be deemed to refer to an assignee holding an assignment of the Stock Designation
Option with respect to such Capital  Stock,  and the terms "party" and "parties"
shall be deemed to include that assignee.

     10. Purchase Price of the Capital Stock.

     (a) The purchase price ("Purchase Price") due and payable by the Designated
Successor upon exercise of the Stock Designation Option shall be as follows:

          (i) Upon the  occurrence  of any event  described in Sections 5(i) and
     (ii), an amount equal to the Appraised Value of the Capital Stock;

          (ii) Upon the occurrence of any event described in Sections 5(a)(iii),
     (iv), (v), (vi), (vii),  (viii),  (ix), (x), (xi) or (xii), an amount equal
     to ___% of the Appraised Value of the Stock.

     (b) Determination of Appraised Value of Stock.


                                      -6-
<PAGE>

          (i) For purposes of this Agreement,  the Appraised Value of a share of
     Capital Stock of the New PC shall be the Net Value of the New PC divided by
     the total number of  outstanding  shares of Capital  Stock of the New PC on
     the Valuation Date.

          (ii) The Net Value of the New PC shall be determined by appraisal. The
     MSO and Dr. Grove (or his successor or representative) shall each select an
     independent appraiser, who is experienced in valuing businesses such as the
     New PC.  Each  party  shall bear the costs of their own  appraisal.  If the
     difference  between the appraised  value set by the two  appraisers is less
     than or equal to ten percent of the greater  appraised value,  then the Net
     Value of the New PC  shall be the  average  of the two  appraisals.  If the
     difference between the appraised value set by the two appraisers is greater
     than ten percent, the appraisers shall select a third appraiser and the Net
     Value  of the New PC  shall  be the  appraised  value  as set by the  third
     appraiser.  The costs of the third  appraisal shall be borne equally by the
     buying and the selling party.

          (iii)  the  "Valuation  Date"  shall  be the  last  day  of the  month
     preceding the date on which any Stock Designation Exercise Notice is given.

     (b) Payment of Purchase  Price.  The  Purchase  Price upon  exercise of the
Stock Designation Option shall be paid by the Designated  Successor  executing a
nonrecourse,  negotiable  promissory  note,  secured by the Capital Stock of Dr.
Grove.  The  note  shall  be for a term of five  years,  with  interest  payable
quarterly  in arrears  at the  mid-term  Applicable  Federal  Rate with  monthly
compounding  published  by the  Internal  Revenue  Service  from time to time in
accordance with Section 1274(d) of the Internal Revenue Code of 1986, as amended
(the "Code") or any successor provision of the Code, provided however,  that the
Designated  Successor  shall be  permitted  to  prepay  such  note at any  time.
Principal  shall be payable in five equal  annual  installments  commencing  six
months after the closing date.

     (c) Purchase From Dr. Grove's Estate.

          (i) Upon the  death of Dr.  Grove  and  receipt  of  notice of a Stock
     Designation  Exercise  Notice,  Dr. Grove's personal  representative  shall
     apply for and obtain any necessary  court approval or  confirmation  of the
     sale of Dr. Grove's shares of Capital Stock pursuant to this Agreement. The
     representative  of the  estate of Dr.  Grove and the  Designated  Successor
     shall  complete  such sale as soon after the date of death as  practicable,
     but no later than 180 days after such event.

          (ii) The death of Dr. Grove's spouse,  if any, shall not be considered
     the death of Dr. Grove for purposes of this Agreement.

          (iii) The estate of Dr. Grove shall bear, and hold the New PC harmless
     from,  all costs and  expenses  incurred as a result of securing  any court
     orders,  court  decrees,  court  approvals or  inheritance  tax  clearances
     required to enable the estate of Dr.  Grove to  transfer to the  Designated
     Successor  full legal and equitable  tax-free title to the Capital Stock of
     Dr. Grove.


                                      -7-

     (b) Other Purchases. Except for purchases of Capital Stock upon exercise of
the Stock  Designation  Option  pursuant to Section  5(a)(i)  hereof,  all other
purchases of Capital Stock  pursuant to such Option shall close thirty (30) days
after the date of any Stock  Designation  Exercise  Notice  ("Closing"),  unless
extended by the parties.

     11. Insurance.

     (a) In order to  insure  the  MSO's  interest  in the  Management  Services
Agreement and under this Agreement, Dr. Grove hereby consents to the acquisition
and maintenance in force of a disability  insurance  policy and a life insurance
policy on Dr. Grove ("Insurance Policies").  The life insurance policy may be in

facilitate the acquisition of any such Insurance Policy by the MSO.

     (b)  The  Insurance  Policies  shall  name  the New PC as  sole  owner  and
beneficiary of such policies.

     (c) As long as the Insurance Policies provided for herein are in full force
and effect,  the MSO shall pay all  premiums  falling  due on all such  policies
issued to it subject to this Agreement.

     (d) No insurance company that has issued or shall issue an Insurance Policy
or  Policies to the MSO as  permitted  under this  Agreement  shall be under any
obligation  with respect to the  performance of the terms and conditions of this
Agreement.  Any such company  shall be bound only by the terms of the  Insurance
Policy or Policies which it has issued or shall  hereafter  issue and shall have
no liability except as set forth in its policies.

     12. Representations. The New PC and Dr. Grove each represent and warrant to
the MSO and OMEGA that as of the day and year first above written and during the
term of this Agreement,  Exhibit A is a true and complete listing of the Capital
Stock, as revised from time to time pursuant to this Agreement.

     13. Restriction on Transfer.

     (a) Except to the extent and in the manner  provided in this  Agreement  or
with the  express  prior  written  consent  of the MSO which may be  granted  or
withheld in its absolute discretion, Dr. Grove shall not sell, assign, transfer,
pledge or  otherwise  dispose  (including  by gift or  otherwise)  of any of his
shares of the Capital Stock.

     (b)  Issuance of Stock;  Change in  Ownership;  Mergers and  Consolidation.

of  this  Agreement,  Dr.  Grove  shall  deliver  to the  MSO  all  certificates
heretofore issued representing all of the shares of Capital Stock held of record
or beneficially  owned by Dr. Grove. Each such certificate shall have affixed to
the back of the certificate a legend substantially as follows:

     including  the  right to  dispose  of the  securities  represented  by this
     certificate  or any interest  therein,  are subject to and  restricted by a
     certain Stock Put/Call Option and Successor Designation Agreement,  dated ,
     199___,  among  the New PC,  the  holder  hereof  and the MSO and OMEGA (as
     defined  therein).  The New PC will mail  without  charge to any  holder of

(and/or the  Designated  Successor)  shall be  authorized  to complete the Stock
Powers,  attach  them to the  certificates  and tender the same to the  transfer
agent for the New PC for  reissuance  in the name of the  Designated  Successor.

     18. Alternative Dispute Resolution.

     (a) If a dispute  arises  under this  Agreement  which  cannot be  resolved
informally  by the  parties,  any party may invoke the  procedures  set forth in
Exhibit D hereto and the parties agree to use these procedures, except paragraph
(b) of this Section 17, prior to any party  pursuing other  available  remedies.
The parties  will meet and attempt in good faith to resolve any  controversy  or
claim arising out of or relating to this Agreement.

     (b) Notwithstanding anything in this Section 17 to the contrary:

          (i) Nothing in this Section 17 shall preclude any party from seeking a
     preliminary  injunction  or other  provisional  relief,  either prior to or
     during the proceeding provided for in this section, if in its judgment such
     action is necessary to avoid  irreparable  damage or to preserve the status
     quo.

          (ii)  The  parties  shall  accept  as  correct,   final,  binding  and
     conclusive the determination of the Net Value of the New PC as set forth in
     Section  10(b),  and  such  determination  shall  not  be  subject  to  the
     provisions of this Section 17. Disputes as to the proper  interpretation of
     the provisions of this Agreement which describe how those amounts are to be
     calculated, however, shall be subject to the provisions of this Section 17.

connection  with this  Agreement  or any  related  agreement,  as to which legal
action  nevertheless  occurs, each party hereby irrevocably waives all rights it
may have to demand a jury trial.  This waiver is  knowingly,  intentionally  and
voluntarily  made by the  parties  and each  party  acknowledges  that no person
acting  on behalf of the  other  party  has made any  representation  of fact to
induce this  waiver of trial by jury or in any way  modified  or  nullified  its
effect.  The parties each further  acknowledge  that it has been represented (or
has had the  opportunity to be represented) in the signing of this Agreement and
in the making of this waiver by independent  legal counsel,  selected of its own
free will,  and that it has had the  opportunity  to discuss  this  waiver  with
counsel.  Each party further  acknowledges  that it has read and understands the
meaning and ramifications of this waiver provision.

                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A. Method of Invoking ADR Procedures

     1.  These  procedures  may be invoked  by any party to an  agreement  which
incorporates  these  procedures  by  giving  written  notice to the other of the
dispute  and   designating  a  person  with   decision-making   authority   (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required  to respond to the  disputing  party's  notice
within five (5) business days by designating in writing its own  representative.
A party may choose  more than one person to  represent  it. If a party  appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties,  each acting  through its  representative,  shall meet at a
mutually  acceptable  time  and  place  within  five  business  days  after  the
non-disputing party designates its representative to the other. At that meeting,
the  parties  shall  attempt  in good faith to  negotiate  a  resolution  of the
dispute,  or  failing  that,  to agree on a method  for  resolving  the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer  period of time as the parties may mutually  agree,  the parties have not
succeeded in  negotiating  a resolution of the claim or dispute or agreeing on a
dispute  resolution  mechanism,  they shall  submit the dispute to  mediation in
accordance with the procedures set forth herein.

     4. The  parties  will  jointly  appoint a mutually  acceptable  mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above,  then the parties  shall select a neutral third party from
the Center for Public Resources,  New York, New York ("CPR") Panels of Neutrals,
with the  assistance  of CPR,  unless the parties  agree  otherwise in finding a
mutually acceptable mediator.

     5. The New PC and the MSO shall  each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR.

     6. The parties  agree to  participate  in good faith in the  mediation  and
negotiations  related thereto for a period of thirty (30) days from  appointment
of a mediator by any of the parties or the CPR.


                                      -18-
<PAGE>

B.   Mediation procedures

     1. The mediator shall be neutral and impartial.

     2. The mediator shall control the procedural aspects of the mediation.  The
parties will cooperate fully with the mediator.

     (a)  The  mediator  is free to meet and  communicate  separately  with each
          party.

     (b)  The mediator will decide when to hold joint  meetings with the parties
          and when to hold  separate  meetings.  There shall be no  stenographic
          record of any meeting. Formal rules of evidence will not apply.

     (c)  The mediator may request that there be no direct communication between
          the parties or between their attorneys  without the concurrence of the
          mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its  officers and an attorney.  Each party will have a  representative  fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator  will not transmit  information  received from any party to
another  party or any  third  person  unless  authorized  to do so by the  party
transmitting the information.

     6. The entire  process is  confidential.  The parties and the mediator will
not disclose information  regarding the process,  including settlement terms, to
third persons,  unless the parties otherwise agree. The process shall be treated
as a compromise  negotiation  for purposes of the Federal  Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing  administrative  and/or  judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

     (a)  The mediator will be disqualified  as a witness,  consultant or expert
          in any pending or future investigation,  action or proceeding relating
          to the subject matter of the mediation  (including any  investigation,
          action  or  proceeding  which  involves  persons  not  party  to  this
          mediation); and


                                      -19-
<PAGE>

     (b)  The mediator  and any  documents  and  information  in the  mediator's
          possession will not be subpoenaed in any such investigation, action or
          proceeding,  and all  parties  will  oppose  any  effort  to have  the
          mediator and documents subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.

     10. The mediator,  if a lawyer,  may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator  shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written  notice to the parties
(i) for overriding personal reasons,  (ii) if the mediator believes that a party
is not acting in good faith,  or (iii) if the  mediator  concludes  that further
mediation efforts would not be useful.

C.   Binding Arbitration

     If the  parties do not resolve the  dispute  through  mediation  within the
period provided in Part A above,  the parties shall submit the matter to binding
arbitration  in Boston,  Massachusetts  before a qualified  sole  arbitrator  in
accordance with the then current CPR Rules for  Non-Administered  Arbitration of
Business  Disputes.  The sole  arbitrator  shall be agreed  upon by the  parties
within  twenty  (20) days  after  either  party  elects  to submit  any issue to
arbitration or, failing that,  shall be selected by CPR. A qualified  arbitrator
is one who is familiar  with the  principal  subject  matter of the issues to be
arbitrated  such as by way of example,  healthcare  services  industry  matters,
management  consulting  services  generally  or business  law/corporate  matters
generally.  Judgment upon the award rendered by the arbitrator may be entered in
any court having  jurisdiction.  The arbitrator  shall not have the authority to
award multiple, punitive or consequential damages under any circumstances.

If the MSO desires to exercise its Put Option, the MSO shall give written notice
of such election to the New PC and Dr. Churosh at least twenty (20) calendar
days prior to the date specified in such notice as the date for the closing of
the Put Option. Any exercise of the Put Option by the MSO shall be made by an
aggregate payment of the amounts computed under Clauses (a) and (b) of this
Section 2 (collectively, the "Put Price").

require the MSO, upon termination of the Management Services Agreement by the
New PC under Section 10.1 thereof, to:



                                      -2-
<PAGE>

          (a) Sell to the New PC all of the leasehold improvements, fixtures,
     furniture, furnishings and equipment comprising or located at the
     Orthodontic Offices, including all replacements and additions thereto made
     by the MSO pursuant to the performance of its obligations under the
     Management Services Agreement and all other assets, including inventory and
     supplies and intangibles, set forth on the Balance Sheet to reflect
     operations of the MSO in respect of the Orthodontic Offices, including
     depreciation, amortization and other adjustments of such assets shown on
     such Balance Sheet; and

          (b) Assign to, or grant a waiver in favor of, the New PC, the
     restrictive covenants provided for in Section 3.7 of the Management
     Services Agreement and in the applicable Employment Agreement with Dr.
     Churosh contemplated thereunder, and any goodwill and other intangible
     assets set forth on the Balance Sheet, reflecting amortization or
     depreciation of the restrictive covenants, and any goodwill and other
     intangible assets; and

          (c) Assign to the New PC (which it shall assume) all debt and all
     contracts, payables and leases which are obligations of the MSO and which
     relate solely to the performance of its obligations under the Management
     Services Agreement or the properties subleased in respect of the
     Orthodontic Offices.

If the New PC desires to exercise its Call Option, the New PC shall give written
notice of such election to the MSO at least twenty (20) calendar days prior to
the date specified in such notice as the date for the closing of the Call
Option. Any exercise of the Call Option by the New PC shall be made by an
aggregate payment to the MSO of an amount equal to the sum of (x) the amount of
cash paid to Dr. Churosh under Section 2.1(b)(i) of the Affiliation Agreement,
plus (y) the value of that number of shares of Omega Common Stock issued to Dr.
Churosh under Section 2.1(b)(ii) of the Affiliation Agreement, such value to be
determined by multiplying such number of shares by the average of the last sales
(or closing) price for Omega's Common Stock on Nasdaq (or a national securities
exchange) for each of the sixty (60) trading days immediately preceding the date
the Call Option Notice is delivered to the MSO (collectively, the "Call Price").

     4. Closing and Delivery. The closing ("Closing") of the exercise by the MSO
of the Put Option under Section 2 or of the exercise by the New PC of the Call
Option under Section 3, as the case may be, shall be at the offices of Robinson
& Cole, One Boston Place, Boston, Massachusetts 02108 on the date specified for
such Closing in the written notice of election to exercise such Put Option or
Call Option, as the case may be, or on such other date as the parties may
mutually determine. At the Closing, the New PC, at its election, shall pay cash,
or a combination of cash and return of the shares of Omega Common Stock received
by Dr. Churosh under Section 2.1(b)(ii) of the Affiliation Agreement, such
shares to be valued as provided for in Section 3 hereof, pursuant to exercise by
the New PC of the Call Option, as the case may be. The New PC and Dr. Churosh
shall execute such documents as may be required by the MSO to assume the
liabilities set forth in Section 2(c) or 3(c), as the case may be, and shall use
their respective best efforts to remove the MSO from any liability with respect
to such repurchased assets and with respect to any property leased or subleased
by the MSO. 




                                      -3-

From and after any such Closing, each party shall provide to the other parties
reasonable access to books and records then owned by it to permit such
requesting party to satisfy reporting and contractual obligations which may be
required of it. In addition, following any such Closing, the MSO or its designee
shall have reasonable access during normal business hours to the New PCs
records, including patient records regarding records of collections, expenses
and disbursements as kept by the MSO in performing its obligations under the
Management Services Agreement, and the MSO may copy any or all such records.

Section 10.2 thereof or upon expiration of the Term of the Management Services
Agreement or upon the happening of any of the following events (each of such
termination, expiration or event being hereinafter referred to as a "Transfer
Event"), the MSO shall have the option (the "Successor Designation Option") to
designate a successor orthodontist or successor orthodontists, which person or
persons must be duly licensed orthodontists in the State or otherwise permitted

          (ii) if Dr. Churosh is determined to be permanently disabled so as to
     be unable to render any professional services on behalf of the New PC, as
     determined in accordance with paragraph (b) of this Section 5 below;

          (iii) if Dr. Churosh voluntarily terminates his employment without
     first proposing and obtaining the MSO's approval of a proposed qualified
     successor orthodontist reasonably acceptable to the MSO on behalf of the
     New PC;

          (iv) if Dr. Churosh acts in a criminally or grossly negligent manner
     with respect to the performance of professional orthodontic services
     rendered or to be rendered on behalf of the New PC;

          (v) if Dr. Churosh becomes hospitalized for alcohol or drug abuse;

          (vi) if Dr. Churosh is convicted of a felony;

          (vii) if Dr. Churosh loses his license or is otherwise determined to
     be disqualified from rendering services as an orthodontist for the New PC
     by the applicable dental or other comparable regulatory board of the State;

          (viii) if Dr. Churosh's shares of Capital Stock are or are to be
     transferred voluntarily or by operation of law to any person who is a
     "disqualified person," as defined in the professional 




                                      -4-
<PAGE>

     corporation statute of the Laws of the State;

          (ix) if Dr. Churosh voluntarily files a petition under any bankruptcy
     or insolvency law or a petition for the appointment of a receiver, or makes
     an assignment for the benefit of creditors;

          (x) if Dr. Churosh is subjected involuntarily to such a petition or
     assignment, or any creditor or other persons obtains an attachment or other
     legal or equitable interest in any shares of the Capital Stock of Dr.
     Churosh and such involuntary petition, assignment or attachment is not
     discharged within sixty (60) days after creation;

          (xi) if Dr. Churosh is required to transfer any shares of Capital
     Stock by reason of a judgment, court order or decree or by operation of
     law;

          (xii) if Dr. Churosh retires within the meaning of Paragraph (c) of
     this Section 5; or

          (xiii) if Dr. Churosh desires to sell any of his shares of Capital
     Stock to another orthodontist as contemplated under Section 6 hereof.

     (b) For purposes hereof, "permanent disability" means any illness, injury,
disease or condition, whether mental or physical, which, for a continuous period
of thirty (30) days, (i) prevents Dr. Churosh from performing his duties
competently and adequately as determined by the MSO, or (ii) substantially
impairs the New PC's or Dr. Churosh's ability to practice orthodontics.

     (c) For purposes hereof, "Retirement" of Dr. Churosh shall occur on the
date when Dr. Churosh voluntarily withdraws from the practice of orthodontics at
whatever age or for whatever reason and notifies the New PC that he desires to
be regarded as "Retired" and fails to have first proposed and obtained the MSO's
approval of a qualified successor orthodontist reasonably acceptable to the MSO.

     6. Successor Designation Option Exercise. Except as otherwise herein, upon
exercise of the Successor Designation Option, the Designated Successor may
purchase all or any part of the Capital Stock. The failure of the MSO to
exercise this Successor Designation Option as to all of the Capital Stock at any
one time shall not limit the MSO's right to exercise the Successor Designation
Option with respect to any remaining Capital Stock at any time during the term
of this Agreement. The Successor Designation Option shall also be exercisable by
the MSO as provided in Section 8 below.

         7. Exercise Notice. Any exercise of the Successor Designation Option
shall be accompanied by a written notice (the "Successor Designation Exercise
Notice") to Dr. Churosh(or his successor or representative), specifying the
name, address and information showing the qualifications and suitability of the
Designated Successor to conduct or perform professional services on behalf of
the New PC and number of shares of Capital Stock of Dr. Churosh as to which the
Successor Designation Option is being exercised. Upon the MSO's exercise of the
Successor Designation Option in respect of 




                                      -5-
<PAGE>

any event described in Section 5(a)(iii) or (x) as to all of the shares of
Capital Stock of Dr. Churosh, Dr. Churosh shall execute a Non-Competition
Agreement in the form attached hereto as Exhibit C. The MSO may, at any time,
cancel any Successor Designation Exercise Notice sent by it hereunder.

     8. Right of First Refusal and Sale of Stock. If Dr. Churosh desires to sell
any of the Capital Stock to another orthodontist (a "Purchaser"), he shall first
give notice to the MSO of his intent to sell such Capital Stock ("Notice of
Sale"), giving to the MSO such information as shall be reasonably requested by
it to ascertain the qualifications and suitability of the Purchaser to conduct
or to perform professional services on behalf of the New PC and the terms and
conditions of such proposed sale to the Purchaser. Upon receipt of such Notice,
the Successor Designation Option of the MSO shall become exercisable for a
period of three (3) months, provided however, that the exercise price and terms
of purchase of the Capital Stock shall be no less favorable to Dr. Churosh than
those set forth in the Notice of Sale. In the event the Successor Designation
Option is not exercised during such three (3) month period, Dr. Churoshmay sell
the Capital Stock to the Purchaser, with the consent of the MSO, which consent
shall not be unreasonably withheld, upon the terms and conditions set forth in
the Notice of Sale, provided however, that such sale shall be conditioned: (i)
upon the Purchaser joining in this Agreement and entering into an employment
agreement with the New PC on such terms and conditions as may be approved by the
MSO, and (ii) upon Dr. Churosh executing a Non-Competition Agreement in the form
attached hereto as Exhibit C.

     9. Assignment of the Successor Designation Option The Successor Designation
Option may be assigned by the MSO or any assignee of the MSO to OMEGA or to a
duly licensed orthodontist, by a written assignment, signed by both the MSO and
the assignee. When the context so requires in this Agreement, the term "MSO"
shall be deemed to refer to an assignee holding an assignment of the Successor
Designation Option with respect to such Capital Stock, and the terms "party" and
"parties" shall be deemed to include that assignee.


     10. Purchase Price of the Capital Stock. (a) Purchase Price. The purchase
price ("Purchase Price") due and payable by the Designated Successor upon
exercise of the Successor Designation Option shall be an amount equal to the
product of (a) the aggregate net amount received by the New PC pursuant to
Article 6 and Schedule 3 of the Management Services Agreement for the twelve
(12) calendar months immediately preceding the month in which the Successor
Designation Exercise Notice is delivered to Dr. Churosh (or his successor or
representative) multiplied by (b) a fraction, the numerator of which is the
number of shares of the Capital Stock to be purchased and the denominator of
which is the total number of shares of the Capital Stock outstanding at the time
of such purchase.

     (b) Payment of Purchase Price. The Purchase Price upon exercise of the
Successor Designation Option shall be paid by the Designated Successor executing
a nonrecourse, negotiable promissory note, secured by the Capital Stock of Dr.
Churosh. The note shall be for a term of five years, with interest payable
quarterly in arrears at the mid-term Applicable Federal Rate with monthly
compounding published by the Internal Revenue Service from time to time in
accordance with 




                                      -6-
<PAGE>

Section 1274(d) of the Internal Revenue Code of 1986, as amended (the "Code") or
any successor provision of the Code, provided however, that the Designated
Successor shall be permitted to prepay such note at any time. Principal shall be
payable in five equal annual installments commencing six months after the
closing date.

     (c) Purchase From Dr. Churosh's Estate.

          (i) Upon the death of Dr. Churosh and receipt of notice of a Stock
     Designation Exercise Notice, Dr. Churosh's personal representative shall
     apply for and obtain any necessary court approval or confirmation of the
     sale of Dr. Churosh's shares of Capital Stock pursuant to this Agreement.
     The representative of the estate of Dr. Churosh and the Designated
     Successor shall complete such sale as soon after the date of death as
     practicable, but no later than 180 days after such event.

          (ii) The death of Dr. Churosh's spouse, if any, shall not be
     considered the death of Dr. Churosh for purposes of this Agreement.

          (iii) The estate of Dr. Churosh shall bear, and hold the New PC
     harmless from, all costs and expenses incurred as a result of securing any
     court orders, court decrees, court approvals or inheritance tax clearances
     required to enable the estate of Dr. Churosh to transfer to the Designated
     Successor full legal and equitable tax-free title to the Capital Stock of
     Dr. Churosh.

     (b) Other Purchases. Except for purchases of Capital Stock upon exercise of
the Stock Designation Option pursuant to Section 5(a)(i) hereof, all other
purchases of Capital Stock pursuant to such Option shall close thirty (30) days
after the date of any Stock Designation Exercise Notice ("Closing"), unless
extended by the parties.

     11. Insurance.

     (a) In order to insure the MSO's interest in the Management Services
Agreement and under this Agreement, Dr. Churosh hereby consents to the
acquisition and maintenance in force of a disability insurance policy and a life
insurance policy on Dr. Churosh ("Insurance Policies"). The life insurance

calendar year. Dr. Churosh agrees, at the election of the MSO, to take whatever
actions are necessary to facilitate the acquisition of any such Insurance Policy
by the MSO.

beneficiary of such policies.

                                      -7-
<PAGE>

     (d) No insurance company that has issued or shall issue an Insurance Policy
or Policies to the MSO as permitted under this Agreement shall be under any
obligation with respect to the performance of the terms and conditions of this

Policy or Policies which it has issued or shall hereafter issue and shall have
no liability except as set forth in its policies.

     12. Representations. The New PC and Dr. Churosh each represent and warrant
to the MSO and OMEGA that as of the day and year first above written and during

shall execute and deliver to the MSO, a sufficient number of assignments
separate from certificates, endorsed in blank to cover all of the Stock (the
"Stock Power") held of record or beneficially owned by Dr. Churosh. Upon
execution of this Agreement, Dr. Churosh shall deliver to the MSO all
certificates heretofore issued representing all of the shares of Capital Stock
held of record or beneficially owned by Dr. Churosh. Each such certificate shall
have affixed to the back of the certificate a legend substantially as follows:

     including the right to dispose of the securities represented by this
     certificate or any interest therein, are subject to and restricted by a
     certain Stock Put/Call Option and Successor Designation Agreement, dated ,
     1997, among the New PC, the holder hereof and the MSO and OMEGA (as defined
     therein). The New PC will mail without charge to any holder of these shares
     a copy of such agreement within five (5) days of receipt by the New PC of a
     written request therefor."

     Upon any exercise of the Stock Designation Option by the MSO, the MSO
(and/or the Designated Successor) shall be authorized to complete the Stock
Powers, attach them to 



                                      -8-

     termination of this Agreement without exercise of the Stock Designation
     Option, the MSO shall return all such Stock Powers to Dr. Churosh.

     15. Confidentiality. The parties shall use all good faith efforts to keep
the contents of this Agreement and all other aspects of the negotiations
preceding execution of this Agreement confidential. Unless required by law, the
New PC, Dr. Churosh, and the MSO and OMEGA shall not disclose the contents of

                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A.   Method of Invoking ADR Procedures

     1. These procedures may be invoked by any party to an agreement which
incorporates these procedures by giving written notice to the other of the
dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties, each acting through its representative, shall meet at a
mutually acceptable time and place within five business days after the
non-disputing party designates its representative to the other. At that meeting,
the parties shall attempt in good faith to negotiate a resolution of the
dispute, or failing that, to agree on a method for resolving the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer period of time as the parties may mutually agree, the parties have not
succeeded in negotiating a resolution of the claim or dispute or agreeing on a
dispute resolution mechanism, they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

     4. The parties will jointly appoint a mutually acceptable mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above, then the parties shall select a neutral third party from
the Center for Public Resources, New York, New York ("CPR") Panels of Neutrals,
with the assistance of CPR, unless the parties agree otherwise in finding a
mutually acceptable mediator.

     5. The New PC and the MSO shall each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR.

     6. The parties agree to participate in good faith in the mediation and
negotiations related thereto for a period of thirty (30) days from appointment
of a mediator by any of the parties or the CPR.


                                      -17-

B.   Mediation procedures

     1. The mediator shall be neutral and impartial.

     2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.


          (a) The mediator is free to meet and communicate separately with each
     party.

          (b) The mediator will decide when to hold joint meetings with the
     parties and when to hold separate meetings. There shall be no stenographic
     record of any meeting. Formal rules of evidence will not apply.

          (c) The mediator may request that there be no direct communication
     between the parties or between their attorneys without the concurrence of
     the mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its officers and an attorney. Each party will have a representative fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator will not transmit information received from any party to
another party or any third person unless authorized to do so by the party
transmitting the information.

     6. The entire process is confidential. The parties and the mediator will
not disclose information regarding the process, including settlement terms, to
third persons, unless the parties otherwise agree. The process shall be treated
as a compromise negotiation for purposes of the Federal Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing administrative and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

          (a) The mediator will be disqualified as a witness, consultant or
     expert in any pending or future investigation, action or proceeding
     relating to the subject matter of the mediation (including any
     investigation, action or proceeding which involves persons not party to
     this mediation); and

          (b) The mediator and any documents and information in the mediator's
     possession 





                                      -18-
<PAGE>

     will not be subpoenaed in any such investigation, action or proceeding, and
     all parties will oppose any effort to have the mediator and documents
     subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.

     10. The mediator, if a lawyer, may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons, (ii) if the mediator believes that a party
is not acting in good faith, or (iii) if the mediator concludes that further
mediation efforts would not be useful.

     C. Binding Arbitration If the parties do not resolve the dispute through
     mediation within the period provided in Part A above, the parties shall
     submit the matter to binding arbitration in Boston, Massachusetts before a
     qualified sole arbitrator in accordance with the then current CPR Rules for
     Non-Administered Arbitration of Business Disputes. If the party initially
     raising the dispute to be resolved is New PC or Dr. Churosh, the
     arbitration shall be held in Boston, Massachusetts, and if the party
     initially raising the dispute to be resolved is the MSO or OMEGA, the
     arbitration shall be held in Goodyear, Arizona. The sole arbitrator shall
     be agreed upon by the parties within twenty (20) days after either party
     elects to submit any issue to arbitration or, failing that, shall be
     selected by CPR. A qualified arbitrator is one who is familiar with the
     principal subject matter of the issues to be arbitrated such as by way of
     example, healthcare services industry matters, management consulting
     services generally or business law/corporate matters generally. Judgment
     upon the award rendered by the arbitrator may be entered in any court
     having jurisdiction. The arbitrator shall not have the authority to award
     multiple, punitive or consequential damages under any circumstances.

Agreement, plus (y) the original principal amount of the Purchase Note issued to
Dr. Schneekluth under Section 2.1(b)(ii) of the Affiliation Agreement,  plus (z)
the  value  of that  number  of  shares  of Omega  Common  Stock  issued  to Dr.
Schneekluth under Section 2.1(b)(iii) of the Affiliation  Agreement,  such value

documents as may be required by the MSO to assume the  liabilities  set forth in
Section 2(c) or 3(c),  as the case may be, and shall use their  respective  best
efforts to remove the MSO from any  liability  with respect to such  repurchased
assets and with respect to any property leased or subleased by the MSO. From and
after any such Closing, each party shall provide to the other parties reasonable
access to books and records then owned by it to permit such requesting  party to
satisfy  reporting and contractual  obligations  which may be required of it. In
addition,  following  any  such  Closing,  the MSO or its  designee  shall  have
reasonable access during normal business hours to the New PCs records, including
patient records regarding records of collections,  expenses and disbursements as
kept by the MSO in performing  its  obligations  under the  Management  Services
Agreement, and the MSO may copy any or all such records.

Section 10.2 thereof or upon  expiration of the Term of the Management  Services

Event"),  the MSO  have  the  option  (the  "Designated  Successor  Option")  to

     New PC;

          (iv) if Dr.  Schneekluth  acts in a  criminally  or grossly  negligent
     manner with respect to the performance of professional orthodontic services
     rendered or to be rendered on behalf of the New PC;

          (v) if Dr. Schneekluth becomes hospitalized for alcohol or drug abuse;

          (vi) if Dr.  Schneekluth  is convicted of a felony,  as defined  under
     California or federal law;

          (vii) if Dr. Schneekluth loses his license or is otherwise  determined

                                      -4-
<PAGE>

     dental or other comparable regulatory board of the State;

          (viii) if Dr.  Schneekluth's  shares of Capital Stock are or are to be

     "disqualified  person," as defined in the professional  corporation statute
     of the Laws of the State;

          (ix)  if Dr.  Schneekluth  voluntarily  files  a  petition  under  any
     bankruptcy  or  insolvency  law or a  petition  for  the  appointment  of a
     receiver, or makes an assignment for the benefit of creditors;

          (x) if Dr.  Schneekluth is subjected  involuntarily to such a petition
     or  assignment,  or any creditor or other persons  obtains an attachment or
     other legal or equitable interest in any shares of the Capital Stock of Dr.
     Schneekluth and such involuntary petition,  assignment or attachment is not

orthodontics at whatever age or for whatever reason and notifies the New PC that
he desires to be  regarded as  "Retired"  and fails to have first  proposed  and
obtained the MSO's  approval of a qualified  successor  orthodontist  reasonably
acceptable to the MSO.

     5. Successor Designation Option Exercise.  Except as otherwise herein, upon
exercise of the  Successor  Designation  Option,  the  Designated  Successor may
purchase  all or any  part  of the  Capital  Stock.  The  failure  of the MSO to
exercise this Successor Designation Option as to all of the Capital Stock at any
one time shall not limit the MSO's right to exercise the  Successor  Designation
Option with respect to any  remaining  Capital Stock at any time during the term
of this Agreement. The Successor Designation Option shall also be exercisable by
the MSO as provided in Section 8 below.

                                      -5-
<PAGE>

     6. Exercise Notice. Any exercise of the Successor  Designation Option shall
be accompanied by a written notice (the "Successor Designation Exercise Notice")
to Dr.  Schneekluth(or  his successor or  representative),  specifying the name,
address  and  information  showing the  qualifications  and  suitability  of the
Designated  Successor to conduct or perform  professional  services on behalf of
the New PC and number of shares of Capital Stock of Dr.  Schneekluth as to which
the Successor Designation Option is being exercised.  Upon the MSO's exercise of
the Successor  Designation  Option in respect of any event  described in Section
5(a)(iii)  or (x) as to all of the shares of Capital  Stock of Dr.  Schneekluth,
Dr.  Schneekluth shall execute a Non-Competition  Agreement in the form attached
hereto as Exhibit C. The MSO may, at any time, cancel any Successor  Designation
Exercise Notice sent by it hereunder.

     7. Right of First Refusal and Sale of Stock. If Dr. Schneekluth  desires to
sell any of the Capital Stock to another orthodontist (a "Purchaser"),  he shall
first give notice to the MSO of his intent to sell such Capital  Stock  ("Notice
of Sale"),  giving to the MSO such information as shall be reasonably  requested
by it to  ascertain  the  qualifications  and  suitability  of the  Purchaser to
conduct  or to  perform  professional  services  on behalf of the New PC and the
terms and  conditions of such proposed  sale to the  Purchaser.  Upon receipt of
such  Notice,  the  Successor   Designation  Option  of  the  MSO  shall  become
exercisable  for a period  of  three  (3)  months,  provided  however,  that the
exercise  price and terms of  purchase  of the  Capital  Stock  shall be no less
favorable to Dr.  Schneekluth than those set forth in the Notice of Sale. In the
event the Successor  Designation  Option is not exercised  during such three (3)
month period, Dr. Schneekluth may sell the Capital Stock to the Purchaser,  with
the consent of the MSO, which consent shall not be unreasonably  withheld,  upon
the terms and conditions set forth in the Notice of Sale, provided however, that
such sale shall be conditioned: (i) upon the Purchaser joining in this Agreement
and  entering  into an  employment  agreement  with the New PC on such terms and
conditions  as may be  approved  by the  MSO,  and  (ii)  upon  Dr.  Schneekluth

     8. Assignment of the Successor Designation Option The Successor Designation
Option may be  assigned  by the MSO or any  assignee of the MSO to OMEGA or to a
duly licensed orthodontist,  by a written assignment, signed by both the MSO and
the  assignee.  When the context so requires in this  Agreement,  the term "MSO"
shall be deemed to refer to an assignee  holding an  assignment of the Successor
Designation Option with respect to such Capital Stock, and the terms "party" and
"parties" shall be deemed to include that assignee.

     9. Purchase Price of the Capital Stock.

     (a) The purchase price ("Purchase Price") due and payable by the Designated
Successor upon exercise of the Successor  Designation  Option shall be an amount
equal to the  product of (a) the  aggregate  net amount  received  by the New PC
pursuant to Article 6 and Schedule 3 of the  Management  Services  Agreement for
the twelve (12)  calendar  months  immediately  preceding the month in which the
Successor  Designation  Exercise Notice is delivered to Dr.  Schneekluth (or his
successor or  representative)  multiplied  by (b) a fraction,  the  numerator of
which is the  number of  shares of the  Capital  Stock to be  purchased  and the
denominator  of which  is the

                                      -6-
<PAGE>

total  number of shares of the  Capital  Stock  outstanding  at the time of such
purchase.

     (b) Payment of Purchase  Price.  The  Purchase  Price upon  exercise of the
Stock Designation Option shall be paid by the Designated  Successor  executing a
nonrecourse,  negotiable  promissory  note,  secured by the Capital Stock of Dr.
Schneekluth.  The note shall be for a term of five years,  with interest payable
quarterly  in arrears  at the  mid-term  Applicable  Federal  Rate with  monthly
compounding  published  by the  Internal  Revenue  Service  from time to time in
accordance with Section 1274(d) of the Internal Revenue Code of 1986, as amended
(the "Code") or any successor provision of the Code, provided however,  that the
Designated  Successor  shall be  permitted  to  prepay  such  note at any  time.
Principal  shall be payable in five equal  annual  installments  commencing  six
months after the closing date.

     (c) Purchase From Dr. Schneekluth's Estate.

     shall apply for and obtain any necessary  court approval or confirmation of
     the sale of Dr.  Schneekluth's  shares of Capital  Stock  pursuant  to this
     Agreement.  The  representative  of the estate of Dr.  Schneekluth  and the
     Designated  Successor  shall  complete  such sale as soon after the date of
     death as practicable, but no later than 180 days after such event.

          (ii) The  death of Dr.  Schneekluth's  spouse,  if any,  shall  not be
     considered the death of Dr. Schneekluth for purposes of this Agreement.

          (iii) The estate of Dr.  Schneekluth  shall bear,  and hold the New PC
     harmless from, all costs and expenses  incurred as a result of securing any
     court orders, court decrees,  court approvals or inheritance tax clearances
     required  to  enable  the  estate of Dr.  Schneekluth  to  transfer  to the
     Designated Successor full legal and equitable tax-free title to the Capital
     Stock of Dr. Schneekluth.

     (d) Other Purchases. Except for purchases of Capital Stock upon exercise of
the Stock  Designation  Option  pursuant to Section  5(a)(i)  hereof,  all other
purchases of Capital Stock  pursuant to such Option shall close thirty (30) days
after the date of any Stock  Designation  Exercise  Notice  ("Closing"),  unless
extended by the parties.

     10. Insurance.

     (a) In order to  insure  the  MSO's  interest  in the  Management  Services
Agreement  and under this  Agreement,  Dr.  Schneekluth  hereby  consents to the
acquisition and maintenance in force of a disability insurance policy and a life
insurance policy on Dr. Schneekluth ("Insurance  Policies").  The life insurance
policy may be in an aggregate face amount of up to three times Dr. Schneekluth's
income,  as  shown on the W-2 Form  prepared  by the New PC for the most  recent
calendar  year.  Dr.  Schneekluth  agrees,  at the  election of the MSO, to take
whatever  actions  are  necessary  to  facilitate  the  acquisition  of any such
Insurance Policy by the MSO.

                                      -7-
<PAGE>

     (b)  The  Insurance  Policies  shall  name  the New PC as  sole  owner  and
beneficiary of such policies. The New PC shall be entitled to the cash surrender
value of the policy.

     (c) As long as the Insurance Policies provided for herein are in full force
and effect,  the MSO shall pay all  premiums  falling  due on all such  policies
issued to it subject to this Agreement.

     (d) No insurance company that has issued or shall issue an Insurance Policy
or  Policies to the MSO as  permitted  under this  Agreement  shall be under any
obligation  with respect to the  performance of the terms and conditions of this
Agreement.  Any such company  shall be bound only by the terms of the  Insurance
Policy or Policies which it has issued or shall  hereafter  issue and shall have
no liability except as set forth in its policies.

     11.  Representations.  The New PC and Dr.  Schneekluth  each  represent and
warrant to the MSO and OMEGA that as of the day and year first above written and
during the term of this Agreement,  Exhibit A is a true and complete  listing of
the Capital Stock, as revised from time to time pursuant to this Agreement.

     12. Restriction on Transfer.

with the  express  prior  written  consent  of the MSO which may be  granted  or

transfer, pledge or otherwise dispose (including by gift or otherwise) of any of
his shares of the Capital Stock.

     (b)  Issuance of Stock;  Change in  Ownership;  Mergers and  Consolidation.
Without the prior written consent of the MSO, Dr.  Schneekluth  shall not permit
the New PC to,  and the New PC shall  not,  during  the term of this  Agreement,
issue any stock,  other equity,  or debt of the New PC; permit any change in the
composition or respective percentage ownership of the New PC; merge, consolidate
or otherwise reorganize with or into any other corporation,  partnership, trade,
business,  or the like;  amend or otherwise modify its articles of incorporation
or bylaws;  dissolve;  or enter into any agreement  with any person to do any of
the foregoing without the prior written consent of the MSO.

     13.  Delivery  of  Stock  Power.  Upon  execution  of this  Agreement,  Dr.
Schneekluth  shall  execute  and  deliver  to the MSO,  a  sufficient  number of
assignments  separate from  certificates,  endorsed in blank to cover all of the
Stock  (the  "Stock  Power")  held  of  record  or  beneficially  owned  by  Dr.
Schneekluth.  Upon execution of this Agreement, Dr. Schneekluth shall deliver to
the MSO all  certificates  heretofore  issued  representing all of the shares of
Capital Stock held of record or beneficially owned by Dr. Schneekluth. Each such
certificate  shall  have  affixed  to the  back  of  the  certificate  a  legend
substantially as follows:

                                      -8-

     "The  rights  of any  holder of any share  evidenced  by this  certificate,
     including  the  right to  dispose  of the  securities  represented  by this
     certificate  or any interest  therein,  are subject to and  restricted by a
     certain Stock Put/Call Option and Successor  Designation  Agreement,  dated

     (as defined therein).  The New PC will mail without charge to any holder of
     these  shares a copy of such  agreement  within five (5) days of receipt by
     the New PC of a written request therefor."

     Upon any  exercise  of the Stock  Designation  Option  by the MSO,  the MSO
(and/or the  Designated  Successor)  shall be  authorized  to complete the Stock
Powers,  attach  them to the  certificates  and tender the same to the  transfer
agent for the New PC for  reissuance  in the name of the  Designated  Successor.
Upon any termination of this Agreement without exercise of the Stock Designation
Option, the MSO shall return all such Stock Powers to Dr. Schneekluth.

     14.  Confidentiality.  The parties shall use all good faith efforts to keep
the  contents  of this  Agreement  and all  other  aspects  of the  negotiations
preceding execution of this Agreement confidential.  Unless required by law, the
New PC, Dr.  Schneekluth,  and the MSO and OMEGA shall not disclose the contents
of this Agreement or the negotiations leading to this Agreement to third parties
without the prior  written  consent of the other  parties.  The MSO shall ensure
that  all  of  the   assignees   likewise   comply  with  the   obligations   of
confidentiality  imposed by this Section,  except that the MSO and the assignees
may disclose the contents of such to the extent  required by law or otherwise to
their  respective  agents,  representatives,  contractors,  and employees to the
extent necessary to exercise their respective rights or perform their respective
obligations hereunder.

     16. Term. The term of this Agreement  shall commence as of the day and year

Services Agreement or the exercise (and consummation of the transaction provided
for upon  such  exercise)  of the Put  Option,  the  Call  Option  or the  Stock
Designation  Option  as to all of the  Capital  Stock,  as the  case may be (the

irrevocably waives all rights it may have to demand a jury trial. This waiver is
knowingly,  intentionally  and  voluntarily  made by the  parties and each party

                                    EXHIBIT D


                    ALTERNATIVE DISPUTE RESOLUTION PROCEDURES


A.   Method of Invoking ADR Procedures

     1. These procedures may be invoked by any party to an agreement which
incorporates these procedures by giving written notice to the other of the
dispute and designating a person with decision-making authority (the
"representative") to act on behalf of the disputing party regarding the dispute.
The other party shall be required to respond to the disputing party's notice
within five (5) business days by designating in writing its own representative.
A party may choose more than one person to represent it. If a party appoints
only one representative, one or more of its officers may nonetheless attend such
meetings.

     2. The parties, each acting through its representative, shall meet at a
mutually acceptable time and place within five business days after the
non-disputing party designates its representative to the other. At that meeting,
the parties shall attempt in good faith to negotiate a resolution of the
dispute, or failing that, to agree on a method for resolving the claim or
dispute.

     3. If, within ten (10) business days after the first meeting or within such
longer period of time as the parties may mutually agree, the parties have not
succeeded in negotiating a resolution of the claim or dispute or agreeing on a
dispute resolution mechanism, they shall submit the dispute to mediation in
accordance with the procedures set forth herein.

     4. The parties will jointly appoint a mutually acceptable mediator to
mediate the dispute. If the parties are unable to agree on a mutually acceptable
mediator within five (5) days after the conclusion of the negotiations described
in paragraph 3 above, then the parties shall select a neutral third party from
the Center for Public Resources, New York, New York ("CPR") Panels of Neutrals,
with the assistance of CPR, unless the parties agree otherwise in finding a
mutually acceptable mediator.

     5. The New PC and the MSO shall each bear 50% of the fees and costs of the
mediator and any fees and costs of CPR.

     6. The parties agree to participate in good faith in the mediation and
negotiations related thereto for a period of thirty (30) days from appointment
of a mediator by any of the parties or the CPR.


B.   Mediation procedures



                                      -18-
<PAGE>


     1. The mediator shall be neutral and impartial.

     2. The mediator shall control the procedural aspects of the mediation. The
parties will cooperate fully with the mediator.


     (a)  The mediator is free to meet and communicate separately with each
          party.

     (b)  The mediator will decide when to hold joint meetings with the parties
          and when to hold separate meetings. There shall be no stenographic
          record of any meeting. Formal rules of evidence will not apply.

     (c)  The mediator may request that there be no direct communication between
          the parties or between their attorneys without the concurrence of the
          mediator.

     3. Each party may be represented by more than one person, e.g., one or more
of its officers and an attorney. Each party will have a representative fully
authorized to negotiate a settlement of the dispute present.

     4. The process will be conducted expeditiously.

     5. The mediator will not transmit information received from any party to
another party or any third person unless authorized to do so by the party
transmitting the information.

     6. The entire process is confidential. The parties and the mediator will
not disclose information regarding the process, including settlement terms, to
third persons, unless the parties otherwise agree. The process shall be treated
as a compromise negotiation for purposes of the Federal Rules of Evidence and
state rules of evidence.

     7. The parties will refrain from pursuing administrative and/or judicial
remedies during the mediation process, except as otherwise expressly provided in
the agreement which incorporates these procedures.

     8. Unless all parties and the mediator otherwise agree in writing,

     (a)  The mediator will be disqualified as a witness, consultant or expert
          in any pending or future investigation, action or proceeding relating
          to the subject matter of the mediation (including any investigation,
          action or proceeding which involves persons not party to this
          mediation); and

     (b)  The mediator and any documents and information in the mediator's
          possession will not be subpoenaed in any such investigation, action or
        

                                      -19-
<PAGE>

          proceeding,  and all  parties  will  oppose  any  effort  to have  the
          mediator and documents subpoenaed.

     9. If the dispute goes into arbitration, the mediator shall not serve as an
arbitrator, unless the parties and the mediator otherwise agree in writing.

     10. The mediator, if a lawyer, may freely express views to the parties on
the legal issues of the dispute.

     11. The mediator shall not be liable for any act or omission in connection
with the mediation.

     12. The mediator may withdraw at any time by written notice to the parties
(i) for overriding personal reasons, (ii) if the mediator believes that a party
is not acting in good faith, or (iii) if the mediator concludes that further
mediation efforts would not be useful.

C. Binding Arbitration. If the parties do not resolve the dispute through
mediation within the period provided in Part A above, the parties shall submit
the matter to binding arbitration in Boston, Massachusetts before a qualified
sole arbitrator in accordance with the then current CPR Rules for
Non-Administered Arbitration of Business Disputes. If the party initially
raising the dispute to be resolved is New PC or Dr. Schneekluth, the arbitration
shall be held in Boston, Massachusetts, and if the party initially raising the
dispute to be resolved is the MSO or OMEGA, the arbitration shall be held in
Huntington Beach, California. The sole arbitrator shall be agreed upon by the
parties within twenty (20) days after either party elects to submit any issue to
arbitration or, failing that, shall be selected by CPR. A qualified arbitrator
is one who is familiar with the principal subject matter of the issues to be
arbitrated such as by way of example, healthcare services industry matters,
management consulting services generally or business law/corporate matters
generally. Judgment upon the award rendered by the arbitrator may be entered in
any court having jurisdiction. The arbitrator shall not have the authority to

Section 5 upon giving  ninety (90) days'  written  notice to the Company of such

     5.8. Limitation on Termination  Benefits.  No payments by the Company to or
for the benefit of the Employee under this  Agreement or any other  agreement or
plan  pursuant to which he is entitled to receive  payments or benefit  shall be
non-deductible  to the Company by reason of the operation of Section 280G of the
Internal  Revenue  Code of 1986,  as  amended,  (the  "Code")  or any  successor
provision relating to parachute payments.  Accordingly,  and notwithstanding any
other provision of this Agreement or any such agreement or plan, if by reason of
the  operation of said Section 280G,  any such payments  exceed the amount which
can be deducted by the Company,  such  payments  shall be reduced to the maximum
amount  which can be  deducted  by the  Company.  To the  extent  that  payments
exceeding such maximum deductible amount have been made to or for the benefit of
the  Employee,  such excess  payments  shall be  refunded  to the  Company  with
interest thereon at the applicable Federal Rate determined under Section 1274(d)
of the Code,  compounded  annually,  or at such other rate as may be required in
order that no such payments shall be  non-deductible to the Company by reason of
the  operation of said Section  280G.  To the extent that there is more than one
method of reducing  the  payments to bring them within the  limitations  of said
Section  280G,  the  Employee  shall  determine  which method shall be followed,
provided that if the Employee fails to make such determination within forty-five
(45) days after the  Company  has sent him  written  notice of the need for such
reduction,  the Company may determine the method for such  reduction in its sole
discretion.

     5.9  Determination  of  Termination  Benefits.  If any dispute  between the
Company and the  Employee as to any of the amounts to be  determined  under this
Section 5, or the method of calculating such amounts,  cannot be resolved by the
Company and the  Employee,  either  party after  giving  three (3) days  written
notice to the other,  may refer the dispute to a partner in the Boston office of
a firm of  independent  certified  public  accountants  selected  jointly by the
Company and the Employee.  The determination of such partner as to the amount to
be determined  under this Section 5 and the method of  calculating  such amounts
shall be final and  binding on both the Company  and the  Employee.  The Company
shall bear the costs of any such determination.

     6. Severance Compensation.

     6.1.  Termination  Upon  Change in  Control or  Termination  Other Than For
Cause.  In the event the  Employee's  employment  is terminated in a Termination
Upon a Change in Control or a  Termination  Other Than For Cause,  the  Employee
shall be paid as severance  compensation the Base Salary (at the rate payable at
the time of such  termination)  for the longer of (a) twelve  (12) months or (b)
the remaining term of this Agreement, on the dates specified in Subsection 4.1.

     Notwithstanding  any provision in this Subsection 6.1 to the contrary,  the
Employee may, in the Employee's sole discretion,  by delivery of a notice to the
Company  within  thirty  (30)  days  following  a  Termination  Upon a Change in
Control,  elect to receive from the Company a lump sum severance payment by bank
cashier's  check equal to the present  value of the flow of cash  payments  that
would  otherwise be paid to the Employee  pursuant to this  Subsection 6.1. Such
present  value shall be  determined  as of the date of delivery of the notice of
election  by the  Employee  and shall be based on a  discount  rate equal to the
interest rate on 90-day United States  Treasury  bills,  as reported in the Wall
Street Journal, or similar publication,  on the date of delivery of the election
notice.  If the Employee  elects to receive a lump sum  severance  payment,  the
Company shall make such payment to the Employee  within ten (10) days  following
the date on which the Employee notifies the Company of the Employee's election.

     In addition to the severance payment payable under this Subsection 6.1, the
Employee  shall be entitled to an  accelerated  vesting of any awards granted to
the Employee under the Company's Incentive Stock Plan.

     6.2.  Termination  Upon  Any  Other  Event.  In the  event  of a  Voluntary
Termination,  Termination  For Cause,  termination  by reason of the  Employee's
disability pursuant to Subsection 5.5 or termination by reason of the Employee's
death  pursuant to Subsection  5.6, the Employee or his estate shall not be paid
any severance compensation.


     7. Obligations Contingent on Performance.

     The  obligations  of  the  Company  under  this  Agreement,  including  its
obligation to pay the compensation provided for herein, shall be contingent upon
the Employee's performance of his obligations under this Agreement.

     8. Confidentiality.

     The Employee agrees to hold in strict confidence all information concerning
any matters  affecting  or relating to the  business of the  Company,  including
without limiting the generality of the foregoing its manner of operation, plans,
protocols,  processes,  computer programs, tenant lists, client lists, marketing
information  and analysis,  or other data,  without regard to whether all of the
foregoing matters will be deemed  confidential or material.  The Employee agrees
that he will not,  directly  or  indirectly,  use any such  information  for the
benefit  of others  than the 


                                       7
<PAGE>


Company  or  disclose  or  communicate  any of such  information  in any  manner
whatsoever  other  than  to  the  directors,  officers,  employees,  agents  and
representatives  of the Company who need to know such information,  who shall be
informed by the  Employee of the  confidential  nature of such  information  and
directed by the  Employee  to treat such  information  confidentially.  Upon the
Company's  request,  the Employee shall return all information  furnished to him
related to the business of the Company.

     The above  limitations on use and disclosure shall not apply to information
which the Employee can demonstrate: (a) was known to the Employee before joining
the  Company and was not  contributed  to the  Company by the  Employee;  (b) is
learned by the  Employee  from a third party  entitled  to  disclose  it; or (c)
becomes  known  publicly  other than through the  Employee.  The parties  hereto
stipulate  that all such  information is material and  confidential  and gravely
affects the effective and successful  conduct of the business of the Company and
the  Company's  good will,  and that any  breach of the terms of this  Section 8
shall be a material breach of this Agreement.  The terms of this Section 8 shall
remain in effect  during the term of this  Agreement and for a period of two (2)
years thereafter.

     9. Use of Proprietary Information.

     The Employee  recognizes that the Company possesses a proprietary  interest
in all of the information described in Section 8 and has the exclusive right and
privilege to use,  protect by  copyright,  patent or trademark,  manufacture  or
otherwise  exploit the processes,  ideas and concepts  described  therein to the
exclusion of the Employee,  except as otherwise  agreed  between the Company and
the  Employee in  writing.  The  Employee  expressly  agrees that any  products,
inventions,  discoveries  or  improvements  made by the Employee,  his agents or
affiliates,  during the term of this  Agreement,  based on or arising out of the
information  described  in Section 8 shall be the  property  of and inure to the
exclusive  benefit of the Company.  The Employee further agrees that any and all
products,  inventions,  discoveries  or  improvements  developed by the Employee
(whether or not able to be protected by copyright,  patent or trademark)  during
the  course of his  employment,  or  involving  the use of the  Company's  time,
materials  or other  resources,  shall be promptly  disclosed to the Company and
shall become the exclusive property of the Company.

     10. Non-Competition Agreement.

      10.1.  Non-Competition.  The Employee agrees that, during the term of this
Agreement and for a period of one (1) year thereafter, he shall not, without the
prior  written  consent of the Company,  directly or  indirectly,  own,  manage,
operate, control, be connected with as an officer, employee, partner, consultant
or otherwise,  or otherwise  engage or participate  in, except as an employee of
the Company,  or any  corporation  directly or indirectly  controlled by it, any
corporation or other business entity engaged in providing management services to
the  orthodontic  industry;  provided,  however,  that the  Employee may own and
operate his own consulting  business that provides management and other services
to the  orthodontic  industry and provided  further  that, in the event that the
Employee  is  receiving  severance   compensation  under  Section  6.1  of  this
Agreement,  his  obligation  not to compete with the Company  under this Section
10.1 shall cease when such payments cease (or would have ceased absent a request
by the


                                       8
<PAGE>


Employee for a lump sum payment).  Notwithstanding the foregoing,  the ownership
by the  Employee of less than two percent  (2%) of any class of the  outstanding
capital  stock of any  corporation  conducting a business  competitive  with the
Company  which is  regularly  traded on a  national  securities  exchange  or an
over-the-counter market shall not be a violation of the foregoing covenant.

     The Employee hereby  acknowledges  and agrees that the provisions set forth
in this Subsection  10.1  constitute a reasonable  restriction on his ability to
compete with the Company.

     10.2. Non-Solicitation.  During the term of this Agreement and for a period
of one (1) year thereafter,  the Employee shall not contact or solicit, directly
or  indirectly,  any customer,  client,  affiliate  orthodontist  or orthodontic
entity,   tenant  or  account  whose  identity  the  Employee  obtained  through
association with the Company,  regardless of the  geographical  location of such
customer,  client,  affiliate  orthodontist  or  orthodontic  entity,  tenant or
account,  nor shall the Employee,  directly or indirectly,  entice or induce, or
attempt to entice or induce,  any  Employee of the Company to leave such employ,
nor shall the Employee  employ any such person in any business  similar to or in
competition with that of the Company during the term of this Agreement and for a
period of one (1) year thereafter.  The Employee hereby  acknowledges and agrees
that the provisions set forth in this  Subsection  10.2  constitute a reasonable
restriction on his ability to compete with the Company.

     10.3.  Savings  Provision.  The parties  hereto agree that,  in the event a
court  of  competent  jurisdiction  shall  determine  that the  geographical  or
durational elements of this covenant are unenforceable, such determination shall
not render the entire covenant  unenforceable.  Rather, the excessive aspects of
the covenant  shall be reduced to the threshold  which is  enforceable,  and the
remaining aspects shall not be affected thereby.

     10.4.  Equitable  Relief.  The  Employee  acknowledges  that the  extent of
damages to the Company  from a breach of Sections 8, 9 and 10 of this  Agreement
would not be readily quantifiable or ascertainable,  that monetary damages would
be inadequate to make the Company whole in case of such a breach, and that there
is not and would not be an adequate remedy at law for such a breach.  Therefore,
the Employee  specifically  agrees that the Company is entitled to injunctive or
other equitable  relief from a breach of Sections 8, 9 and 10 of this Agreement,
and hereby waives and  covenants not to assert  against a prayer for such relief
that there exists an adequate remedy at law, in monetary damages or otherwise.

     11. Entire Agreement.

     This Agreement  contains the complete  agreement  concerning the employment
arrangement  between the parties and shall, as of the effective date,  supersede
all other  agreements  or  arrangements  between the parties  with regard to the
subject matter hereof.


     12. Binding Agreement.


                                       9

parties hereto and their respective heirs, legal representatives, successors and
assigns.  The  obligations  of the  Company  under this  Agreement  shall not be
terminated by reason of any liquidation,  dissolution,  bankruptcy, cessation of
business or similar event relating to the Company.  This Agreement  shall not be

Company,  but shall be binding upon and inure to the benefit of the surviving or
resulting entity.

this Agreement,  or the rights or obligations of the parties thereunder,  unless
such waiver or modification is in writing, duly executed as aforesaid.

     14. Severability.

     All agreements  and covenants  contained  herein are severable,  and in the
event any of them shall be held to be invalid or  unenforceable  by any court of

                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT, dated as of May 1, 1997, between DR. DEAN C. BELLAVIA,
of Buffalo, New York (the "Employee") and OMEGA ORTHODONTICS, INC., a Delaware

                                   WITNESSETH:

         WHEREAS, the Employee desires to be employed by the Company, and the
Company desires to employ the Employee, on the terms, covenants and conditions
hereinafter set forth in this Agreement.

         NOW, THEREFORE, for the reasons set forth above, and in consideration
of the mutual promises and agreements hereinafter set forth, the Company and the
Employee agree as follows:

         1.       Employment and Duties.

         1.1 Employment. Subject to the terms and conditions set forth in this
Agreement, the Company hereby employs and engages the Employee to hold the title
of Director of Affiliate Programs and perform the duties of such position as
designated by the board of directors of the Company (the "Board of Directors").
The Employee hereby accepts such employment and agrees to serve the Company in
such capacity for the period of this Agreement.

         1.2 Duties. The Employee's duties shall include: all design, scheduling
the installation and following up on the effectiveness of all the managerial
systems used by the Company's affiliated orthodontic practices as outlined in
the Affiliate Optimization Program, as revised from time to time; management of
the effectiveness and productivity of the consultants used to optimize and
maintain the affiliate practices' programs; and additional duties that the
Employee and the Company agree upon.

         2.       Term of Employment.

         The term of this Agreement shall be for a period of three (3) years
commencing on the closing of the initial public offering of the Company's common
stock (the "Effective Date") and expiring at midnight on the day immediately
preceding the third anniversary of the Effective Date, unless terminated prior
to that date as provided in Section 7 of this Agreement. Commencing on the third
anniversary of the Effective Date, and on each anniversary thereafter, the term
of this Agreement shall be automatically extended for an additional year, unless
either party gives notice of termination as provided in Subsection 5.7 of this
Agreement.

         3.       Devotion to Duties.

         The Employee agrees that during the period that he is employed
hereunder he shall devote the time necessary to complete his duties hereunder
and shall use his best efforts to promote 




<PAGE>

the interests of the Company. The parties acknowledge and agree that,
notwithstanding the foregoing, the Employee may continue his orthodontic
consulting business and may continue to pursue his academic and writing
endeavors; provided, however, that such endeavors shall neither materially
adversely affect or impair his ability to meet his obligations hereunder.


         4.       Compensation of Employee.

         4.1. Affiliate Payments and Base Salary.During the term of this
Agreement, the Company shall pay to the Employee as compensation for the
services to be performed by the Employee hereunder as follows:

                  (a) Beginning on the Effective Date, the Company shall pay the
         Employee $10,000 per month as an advance (the "Advance Amount") for
         compensation earned according to the following schedule: (i) one-time
         payments of Seven Thousand Five Hundred Dollars ($7,500) for each
         orthodontic practice affiliated with the Company in which the Employee
         initiates the optimization of the Omega Exceptional Practice Model (the
         "Model") (the "New Affiliate Payments"); and (ii) Two Hundred Eight and
         333/1000 Dollars ($208.333) per month for each orthodontic practice
         affiliated with the Company in which the optimization of the Model was
         previously initiated by the Employee (the "Existing Affiliate Payments"
         and, collectively, with the New Affiliate Payments, the "Affiliate
         Payments"). At the end of each three full calendar months following the
         month in which the Effective Date occurs (a "Quarter"), the Company
         shall review the Advance Amount and the Affiliate Payments for such
         Quarter. If the Advance Amount exceeds the Affiliate Payments, the
         Advance Amount for the next Quarter shall be reduced by the amount of
         such excess.

                  (b) Beginning with the first month after the Company has
         completed affiliations with an aggregate of fifteen orthodontic
         practices, the Company shall pay the Employee at the rate of $10,000
         per month (the "Base Salary") for that month and each month thereafter
         during the remainder of the term of this Agreement.

                 (c) The Affiliate Payments and the Base Salary shall be payable
         in semi-monthly installments in accordance with the Company's normal

information, who shall be informed by the Employee of the confidential nature of
such information and directed by the Employee to treat such information

Section 8 shall be a material breach of this Agreement. The terms of this
Section 8 shall remain in effect during the term of this Agreement and for a
period of two (2) years thereafter.

Company and shall be used exclusively by the Company.

forms, systems and concepts used to develop certain of the Company's manuals,
forms, systems and concepts are copyrighted property of the Employee and The
Bio-Engineering Co., of Buffalo, NY (the "Employee Proprietary Information"),
and that the Employee and The Bio-Engineering Co. retain the legal rights to the
Employee Proprietary Information and may continue to use, publish and do
whatever the Employee and The Bio-Engineering Co. deem appropriate with the
Employee Proprietary Information. The Company acknowledges and agrees that the
Company may only use the Employee Proprietary Information for the betterment of
its affiliated orthodontic practices and may not publish, sell or in any way use
the Employee Proprietary Information 




                                       9
<PAGE>

for any other purpose or transfer to any other entity that the Company wishes
to, without the prior written consent of the Employee and The Bio-Engineering
Co.

         10.      Non-Competition Agreement.

         10.1. Non-Competition. The Employee agrees that, during the term of
this Agreement and for a period of one (1) year thereafter, he shall not,
without the prior written consent of the Company, directly or indirectly, own,
manage, operate, control, be connected with as an officer, employee, partner,
consultant or otherwise, or otherwise engage or participate in, except as an
employee of the Company, or any corporation directly or indirectly controlled by
it, any corporation or other business entity engaged in providing management
services to the orthodontic industry, except his orthodontic consulting business
referred to in Section 3 hereof. Notwithstanding the foregoing, the ownership by
the Employee of less than two percent (2%) of any class of the outstanding
capital stock of any corporation conducting a business competitive with the
Company which is regularly traded on a national securities exchange or an
over-the-counter market shall not be a violation of the foregoing covenant.

         The Employee hereby acknowledges and agrees that the provisions set
forth in this Subsection 10.1 constitute a reasonable restriction on his ability
to compete with the Company.

         10.2. Non-Solicitation. Without the prior written consent of the
Company, during the term of this Agreement and for a period of one (1) year
thereafter, the Employee shall not contact or solicit, directly or indirectly,

Company, regardless of the geographical location of such customer, client,
affiliate orthodontist or orthodontic entity, tenant or account, nor shall the
Employee, directly or indirectly, entice or induce, or attempt to entice or
induce, any other employee of the Company to leave such employ, nor shall the
Employee employ any such person in any business similar to or in competition
with that of the Company during the term of this Agreement and for a period of
one (1) year thereafter. The Employee hereby acknowledges and agrees that the
provisions set forth in this Subsection 10.2 constitute a reasonable restriction
on his ability to compete with the Company.

         10.3. Savings Provision. The parties hereto agree that, in the event a
court of competent jurisdiction shall determine that the geographical or
durational elements of this covenant are unenforceable, such determination shall
not render the entire covenant unenforceable. Rather, the excessive aspects of
the covenant shall be reduced to the threshold which is enforceable, and the
remaining aspects shall not be affected thereby.

         10.4. Equitable Relief. The Employee acknowledges that the extent of
damages to the Company from a breach of Sections 8, 9 and 10 of this Agreement
would not be readily quantifiable or ascertainable, that monetary damages would
be inadequate to make the Company whole in case of such a breach, and that there
is not and would not be an adequate remedy at law for such a breach. Therefore,
the Employee specifically agrees that the Company is entitled to injunctive or
other equitable relief from a breach of Sections 8, 9 and 10 of this Agreement,
and 




                                       10

hereby waives and covenants not to assert against a prayer for such relief that
there exists an adequate remedy at law, in monetary damages or otherwise.

employment arrangement between the parties and shall, as of the effective date,

Company, but shall be binding upon and inure to the benefit of the surviving or
resulting entity.

competent jurisdiction, this Agreement shall be interpreted as if such invalid

     WHEREAS,  the  Employee  desires to be  employed  by the  Company,  and the
Company desires to employ the Employee,  on the terms,  covenants and conditions
hereinafter set forth in this Agreement.

     NOW,  THEREFORE,  for the reasons set forth above,  and in consideration of
the mutual promises and agreements  hereinafter  set forth,  the Company and the
Employee agree as follows:

     1.   Employment.

     Subject  to the  terms and  conditions  set  forth in this  Agreement,  the
Company hereby employs and engages the Employee to hold the title of Director of
Professional  Relations  and Staff  Development  and  perform the duties of such
position  designated  by the board of  directors  of the Company  (the "Board of
Directors"),  which duties shall include,  without limitation,  (a) managing the
Company's affiliate enrollment program through advertising,  seminars,  personal
communication  and  other  appropriate  means  and (b)  training  the  Company's
personnel  and  affiliates  and their  personnel  in  communication  skills  and
interpersonal  relationships.  In such  capacity,  and  subject to review by the
Board  of   Directors,   the  Employee   shall  also  perform  such  duties  and
responsibilities  as may be  assigned  to him from  time to time by the Board of
Directors.  The Employee  hereby accepts such employment and agrees to serve the
Company in such capacity for the period of this Agreement.

     2.   Term of Employment.

     The  term of this  Agreement  shall  be for a period  of  three  (3)  years
commencing on the closing of the initial public offering of the Company's common
stock (the  "Effective  Date") and  expiring at midnight on the day  immediately
preceding the third  anniversary of the Effective Date,  unless terminated prior
to that date as provided in Section 7 of this Agreement. Commencing on the third
anniversary of the Effective Date, and on each anniversary thereafter,  the term
of this Agreement shall be automatically extended for an additional year, unless
either party gives notice of  termination  as provided in Subsection 5.7 of this
Agreement.

     3.   Devotion to Duties.

     The Employee agrees that during the period that he is employed hereunder he
shall devote  substantially  all his business time and attention to the business
and  affairs  of the  Company  and shall use his best  efforts  to  promote  the
interests   of  the   Company.   The   parties   acknowledge   and


<PAGE>


agree that, notwithstanding the foregoing, the Employee may continue his
orthodontic consulting and seminar business; provided, however, that such
business does not materially adversely affect or impair his ability to meet his
obligations hereunder.



     4.   Compensation of Employee.

     4.1.  Affiliate Payments and Base Salary.During the term of this Agreement,
the Company  shall pay to the  Employee as  compensation  for the services to be
performed by the Employee hereunder as follows:

          (a)  Beginning  on the  Effective  Date,  the  Company  shall  pay the
     Employee  $10,000  per  month as an  advance  (the  "Advance  Amount")  for
     compensation  earned  according  to the  following  schedule:  (i) one time
     payments of $2,500 for each  orthodontic  practice that affiliates with the
     Company  following the Effective Date in the month, (ii) $1,250 per day per
     seminar conducted in the offices of an affiliated  orthodontic  practice in
     the month,  and (iii) $300 per affiliated  orthodontic  practice coached in
     the month (the  payments  referred  to in  clauses  (i)  through  (iii) are
     referred to collectively as the "Affiliate  Payments").  At the end of each
     three full calendar months  following the month in which the Effective Date
     occurs (a  "Quarter"),  the Company shall review the Advance Amount and the
     Affiliate  Payments for such  Quarter.  If the Advance  Amount  exceeds the
     Affiliate  Payments,  the  Advance  Amount  for the next  Quarter  shall be
     reduced by the amount of such excess.

          (b)  Beginning  with the first month  after the Company has  completed
     affiliations  with an  aggregate  of  fifteen  orthodontic  practices,  the
     Company  shall pay the Employee at the rate of $10,000 per month (the "Base
     Salary") for that month and each month  thereafter  during the remainder of
     the term of this Agreement.

          (c) The  Affiliate  Payments  and  Base  Salary  shall be  payable  in
     installments  in accordance  with the Company's  normal  payroll  practice.
     Commencing  on the  third  anniversary  of the  Effective  Date and on each
     anniversary  thereafter,   or  as  soon  as  practicable  thereafter,   the
     Compensation  Committee  of  the  Board  of  Directors  (the  "Compensation
     Committee"), or the Board of Directors if the Compensation Committee is not
     then appointed,  shall review the Affiliate Payments or the Base Salary, as
     the case may be, and shall  authorize,  in its  discretion,  an appropriate
     increase thereto.

     4.2.  Bonus.  In addition to the  compensation  set forth elsewhere in this
Section 4, for each year or portion  thereof  during the term of this  Agreement
and any extensions thereof, the Employee shall be eligible to receive a bonus in
an  amount  to be  determined  by the  Compensation  Committee,  or the Board of
Directors  if  the  Compensation  Committee  is  not  then  appointed,   in  its
discretion,  based upon its evaluation of the Employee's performance during such
year or portion thereof.

bonus  compensation  for finding  orthodontic  practices that affiliate with the
Company,  if such a program is adopted by the  Company.  Such  bonuses,  if any,

term he is employed  hereunder,  in all regular  employee  benefit and  deferred

secretarial  assistance as needed for the performance of his duties,  subject to
reimbursement  by the Company as provided in Subsection 4.5 hereof for providing
such office and secretarial assistance.

     4.5. Reimbursement of Expenses.The Company shall provide for the payment or
reimbursement of all reasonable and necessary  expenses incurred by the Employee
in  connection  with the  performance  of his  duties  under this  Agreement  in
accordance with the Company's expense  reimbursement  policy, as such may change
from time to time.

     4.6 Incentive Stock Options. The Company shall grant to the Employee,  upon
the execution of this  Agreement,  an incentive stock option under the Company's
Incentive  Stock Plan to acquire  150,000 shares of the Company's  Common Stock,
par value $.01 per share,  at an  exercise  price  equal to the  initial  public
offering price for the Company's  Common Stock.  Such option shall vest in equal
installments on each of the first three  anniversaries  of the date of execution
of this Agreement.

     5.   Termination of Employment.

     5.1.  Termination  For  Cause.  "Termination  For  Cause,"  as  hereinafter
defined,  may be  effected  by the  Company at any time  during the term of this

Section 5 upon giving  ninety (90) days'  written  notice to the Company of such
termination.

     5.8. Limitation on Termination  Benefits.  No payments by the Company to or
for the benefit of the Employee under this  Agreement or any other  agreement or
plan  pursuant to which he is entitled to receive  payments or benefit  shall be
non-deductible  to the Company by reason of the operation of Section 280G of the
Internal  Revenue  Code of 1986,  as  amended,  (the  "Code")  or any  successor
provision relating to parachute payments.  Accordingly,  and notwithstanding any
other provision of this Agreement or any such agreement or plan, if by reason of
the  operation of said Section 280G,  any such payments  exceed the amount which
can be deducted by the Company,  such  payments  shall be reduced to the maximum
amount  which can be  deducted  by the  Company.  To the  extent  that  payments
exceeding such maximum deductible amount have been made to or for the benefit of
the  Employee,  such excess  payments  shall be  refunded  to the  Company  with
interest thereon at the applicable Federal Rate determined under Section 1274(d)
of the Code,  compounded  annually,  or at such other rate as may be required in
order that no such payments shall be  non-deductible to the Company by reason of
the  operation of said Section  280G.  To the extent that there is more than one
method of reducing  the  payments to bring them within the  limitations  of said
Section  280G,  the  Employee  shall  determine  which method shall be followed,
provided that if the Employee fails to make such determination within forty-five
(45) days after the  Company  has sent him  written  notice of the need for such
reduction,  the Company may determine the method for such  reduction in its sole
discretion.

     5.9  Determination  of  Termination  Benefits.  If any dispute  between the
Company and the  Employee as to any of the amounts to be  determined  under this
Section 5, or the method of calculating such amounts,  cannot be resolved by the
Company and the  Employee,  either  party after  giving  three (3) days  written
notice to the other,  may refer the dispute to a partner in the Boston office of
a firm of  independent  certified  public  accountants  selected  jointly by the
Company and the Employee.  The determination of such partner as to the amount to
be determined  under this Section 5 and the method of  calculating  such amounts
shall be final and  binding on both the Company  and the  Employee.  The Company
shall bear the costs of any such determination.

     6.   Severance Compensation.

      6.1.  Termination  Upon  Change in Control or  Termination  Other Than For
Cause.  In the event the  Employee's  employment  is terminated in a Termination
Upon a Change in Control or a  Termination  Other Than For Cause,  the  Employee
shall be paid as severance  compensation the Base Salary (at the rate payable at
the time of such termination) for


                                       7
<PAGE>


the  longer  of (a)  twelve  (12)  months  or (b)  the  remaining  term  of this
Agreement, on the dates specified in Subsection 4.1.

      Notwithstanding any provision in this Subsection 6.1 to the contrary,  the
Employee may, in the Employee's sole discretion,  by delivery of a notice to the
Company  within  thirty  (30)  days  following  a  Termination  Upon a Change in
Control,  elect to receive from the Company a lump sum severance payment by bank
cashier's  check equal to the present  value of the flow of cash  payments  that
would  otherwise be paid to the Employee  pursuant to this  Subsection 6.1. Such
present  value shall be  determined  as of the date of delivery of the notice of
election  by the  Employee  and shall be based on a  discount  rate equal to the
interest rate on 90-day United States  Treasury  bills,  as reported in the Wall
Street Journal, or similar publication,  on the date of delivery of the election
notice.  If the Employee  elects to receive a lump sum  severance  payment,  the
Company shall make such payment to the Employee  within ten (10) days  following

that he will not,  directly  or  indirectly,  use any such  information  for the
benefit  of others  than the  Company or  disclose  or  communicate  any of such
information  in any manner  whatsoever  other than to the  directors,  officers,
employees,  agents  and  representatives  of the  Company  who need to know such
information, who shall be informed by the Employee of the confidential nature of
such  information  and  directed  by the  Employee  to  treat  such  information
confidentially.  Upon the  Company's  request,  the  Employee  shall  return all
information furnished to him related to the business of the Company.


                                       8
<PAGE>


      The above limitations on use and disclosure shall not apply to information
which the Employee can demonstrate: (a) was known to the Employee before joining
the  Company and was not  contributed  to the  Company by the  Employee;  (b) is
learned by the  Employee  from a third party  entitled  to  disclose  it; or (c)
becomes  known  publicly  other than through the  Employee.  The parties  hereto
stipulate  that all such  information is material and  confidential  and gravely
affects the effective and successful  conduct of the business of the Company and
the  Company's  good will,  and that any  breach of the terms of this  Section 8
shall be a material breach of this Agreement.  The terms of this Section 8 shall
remain in effect  during the term of this  Agreement and for a period of two (2)
years thereafter.

     9.   Use of Proprietary Information.

     The Employee  recognizes that the Company possesses a proprietary  interest
in all of the information described in Section 8 and has the exclusive right and
privilege to use,  protect by  copyright,  patent or trademark,  manufacture  or
otherwise  exploit the processes,  ideas and concepts  described  therein to the
exclusion of the Employee,  except as otherwise  agreed  between the Company and
the  Employee in  writing.  The  Employee  expressly  agrees that any  products,
inventions,  discoveries  or  improvements  made by the Employee,  his agents or
affiliates,  during the term of this  Agreement,  based on or arising out of the
information  described  in Section 8 shall be the  property  of and inure to the
exclusive  benefit of the Company.  The Employee further agrees that any and all
products,  inventions,  discoveries  or  improvements  developed by the Employee
(whether or not able to be protected by copyright,  patent or trademark)  during
the  course of his  employment,  or  involving  the use of the  Company's  time,
materials  or other  resources,  shall be promptly  disclosed to the Company and
shall become the exclusive property of the Company.

     10.  Non-Competition Agreement.

     10.1.  Non-Competition.  The Employee agrees that,  during the term of this
Agreement and for a period of one (1) year thereafter, he shall not, without the
prior  written  consent of the Company,  directly or  indirectly,  own,  manage,
operate, control, be connected with as an officer, employee, partner, consultant
or otherwise,  or otherwise  engage or participate  in, except as an employee of
the Company,  or any  corporation  directly or indirectly  controlled by it, any
corporation or other business entity engaged in providing management services to
the orthodontic industry, except his orthodontic consulting and seminar business
referred to in Section 3 hereof. Notwithstanding the foregoing, the ownership by
the  Employee  of less than two  percent  (2%) of any  class of the  outstanding
capital  stock of any  corporation  conducting a business  competitive  with the
Company  which is  regularly  traded on a  national  securities  exchange  or an
over-the-counter market shall not be a violation of the foregoing covenant.

     The Employee hereby  acknowledges  and agrees that the provisions set forth
in this Subsection  10.1  constitute a reasonable  restriction on his ability to
compete with the Company.

      10.2. Non-Solicitation. During the term of this Agreement and for a period
of one (1) year thereafter,  the Employee shall not contact or solicit, directly
or  indirectly,  any customer,  client,  affiliate  orthodontist  or orthodontic
entity, tenant or account whose identity the Employee


                                       9
<PAGE>


obtained through  association  with the Company,  regardless of the geographical
location of such customer, client, affiliate orthodontist or orthodontic entity,
tenant or account,  nor shall the Employee,  directly or  indirectly,  entice or
induce,  or attempt to entice or induce,  any  Employee  of the Company to leave
such  employ,  nor shall the  Employee  employ any such  person in any  business
similar to or in  competition  with that of the Company  during the term of this
Agreement  and for a period  of one (1) year  thereafter.  The  Employee  hereby
acknowledges  and agrees that the provisions set forth in this  Subsection  10.2
constitute a reasonable restriction on his ability to compete with the Company.

     10.3.  Savings  Provision.  The parties  hereto agree that,  in the event a
court  of  competent  jurisdiction  shall  determine  that the  geographical  or
durational elements of this covenant are unenforceable, such determination shall
not render the entire covenant  unenforceable.  Rather, the excessive aspects of
the covenant  shall be reduced to the threshold  which is  enforceable,  and the
remaining aspects shall not be affected thereby.

     10.4.  Equitable  Relief.  The  Employee  acknowledges  that the  extent of
damages to the Company  from a breach of Sections 8, 9 and 10 of this  Agreement
would not be readily quantifiable or ascertainable,  that monetary damages would
be inadequate to make the Company whole in case of such a breach, and that there
is not and would not be an adequate remedy at law for such a breach.  Therefore,
the Employee  specifically  agrees that the Company is entitled to injunctive or
other equitable  relief from a breach of Sections 8, 9 and 10 of this Agreement,
and hereby waives and  covenants not to assert  against a prayer for such relief
that there exists an adequate remedy at law, in monetary damages or otherwise.

     11.  Entire Agreement.

     This Agreement  contains the complete  agreement  concerning the employment
arrangement  between the parties and shall, as of the effective date,  supersede
all other  agreements  or  arrangements  between the parties  with regard to the
subject matter hereof.

     12.  Binding Agreement.

     This  Agreement  shall be  binding  upon and  inure to the  benefit  of the
parties hereto and their respective heirs, legal representatives, successors and
assigns.  The  obligations  of the  Company  under this  Agreement  shall not be
terminated by reason of any liquidation,  dissolution,  bankruptcy, cessation of
business or similar event relating to the Company.  This Agreement  shall not be
terminated  by reason of any  merger,  consolidation  or  reorganization  of the
Company,  but shall be binding upon and inure to the benefit of the surviving or
resulting entity.

     13.  Modification.

     No waiver or modification  of this Agreement or of any covenant,  condition
or  limitation  herein  contained  shall be valid  unless  in  writing  and duly
executed by the party to be charged  therewith  and no evidence of any waiver or
modification  shall be  offered  or  received  in  evidence  of any  proceeding,
arbitration or litigation between the parties hereto arising out of or affecting


                                       10
<PAGE>


this Agreement,  or the rights or obligations of the parties thereunder,  unless
such waiver or modification is in writing, duly executed as aforesaid.

     14.  Severability.

     All agreements  and covenants  contained  herein are severable,  and in the
event any of them shall be held to be invalid or  unenforceable  by any court of

1.   Granting of Incentive Stock Options.

Incentive Stock Options under the Plan. Directors and Consultants of the
Corporation who are not also Employees shall not be eligible to receive
Incentive Stock Options.

     (b) The purchase price of each share of Stock subject to an Incentive Stock
Option shall not be less than 100% of the Fair Market Value of a share of the
Stock on the date the Incentive Stock Option is granted; provided, however, that
the purchase price of each share of Stock subject to an Incentive Stock Option
granted to a Ten Percent Shareholder shall not be less than 110% of the Fair
Market Value of a share of the Stock on the date the Incentive Stock Option is
granted.

     (c) No Incentive Stock Option shall be exercisable more than ten years from
the date the Incentive Stock Option was granted; provided, however, that an
Incentive Stock Option granted to a Ten Percent Shareholder shall not be
exercisable more than five years from the date the Incentive Stock Option was

                                       3
<PAGE>


     (d) The Committee shall determine and designate from time to time those
Employees who are to be granted Incentive Stock Options and specify the number
of shares subject to each Incentive Stock Option.

     (e) The Committee, in its sole discretion, shall determine whether any
particular Incentive Stock Option shall become exercisable in one or more
installments, specify the installment dates, and, within the limitations herein
provided, determine the total period during which the Incentive Stock Option is
exercisable. Further, the Committee may make such other provisions as may appear
generally acceptable or desirable to the Committee or necessary to qualify its
grants under the provisions of Section 422 of the Code.

     (f) The Committee may grant at any time new Incentive Stock Options to an
Employee who has previously received Incentive Stock Options or other options
whether such prior Incentive Stock Options or other options are still
outstanding, have previously been exercised in whole or in part, or are canceled
in connection with the issuance of new Incentive Stock Options. The purchase
price of the new Incentive Stock Options may be established by the Committee
without regard to the existing Incentive Stock Options or other options.

     (g) Notwithstanding any other provisions hereof, the aggregate fair market
value (determined at the time the option is granted) of the Stock with respect
to which Incentive Stock Options are exercisable for the first time by the
Employee during any calendar year (under all such plans of the Grantee's
employer corporation and its parent and subsidiary corporation) shall not exceed
$100,000.

2. Exercise of Incentive Stock Options. The option price of an Incentive Stock
Option shall be payable on exercise of the option (i) in cash or by check, bank
draft or postal or express money order, (ii) by the surrender of Stock then
owned by the Grantee, or (iii) partially in accordance with clause (i) and
partially in accordance with clause (ii) of this Paragraph. Shares of Stock so
surrendered in accordance with clause (ii) or (iii) shall be valued at the Fair
Market Value thereof on the date of exercise, surrender of such Stock to be
evidenced by delivery of the certificate(s) representing such shares in such
manner, and endorsed in such form, or accompanied by stock powers endorsed in
such form, as the Committee may determine.

3.   Termination of Employment.

     (a) If a Grantee's employment with the Corporation is terminated other than
by Disability or death the terms of any then outstanding Incentive Stock Option
held by the Grantee shall extend for a period ending on the earlier of the date
on which such Stock Option would otherwise expire or three months after such
termination of employment, and such Stock Option shall be exercisable to the
extent it was exercisable as of such last date of employment.

     (b) If a Grantee's employment with the Corporation is terminated by reason
of Disability, the term of any then outstanding Incentive Stock Option held by
the Grantee shall extend for a period ending on the earlier of the date on which
such Stock Option would otherwise expire or twelve months after such termination
of employment, and such Stock Option shall be exercisable to the extent it was
exercisable as of such last date of employment.


                                       4
<PAGE>


     (c) If a Grantee's employment with the Corporation is terminated by reason
of death, the representative of his estate or beneficiaries thereof to whom the
Stock Option has been transferred shall have the right during the period ending
on the earlier of the date on which such Stock Option would otherwise expire or
twelve months after such date of death, to exercise any then outstanding
Incentive Stock Options in whole or in part. If a Grantee dies without having
fully exercised any then outstanding Incentive Stock Options, the representative
of his estate or beneficiaries thereof to whom the Stock Option has been
transferred shall have the right to exercise such Stock Options in whole or in
part.

4.   Stock Appreciation Rights

     (a) Grant. Stock Appreciation Rights related to all or any portion of an
Incentive Stock Option may be granted by the Committee to any Grantee in
connection with the grant of an Incentive Stock Option or unexercised portion
thereof held by the Grantee at any time and from time to time during the term
thereof. Each Stock Appreciation Right shall be subject to such terms and
conditions not inconsistent with the provisions of this Part II as shall be
determined by the Committee and included in the agreement relating to such Stock
Appreciation Right, subject in any event, however, to the following terms and
conditions of this Section 4. Each Stock Appreciation Right may include
limitations as to the time when such Stock Appreciation Right becomes
exercisable and when it ceases to be exercisable that are more restrictive than
the limitations on the exercise of the Incentive Stock Option to which it
relates.

     (b) Exercise. No Stock Appreciation Right shall be exercisable with respect
to such related Incentive Stock Option or portion thereof unless such Incentive
Stock Option or portion shall itself be exercisable at that time. A Stock
Appreciation Right shall be exercised only upon surrender of the related
Incentive Stock Option or portion thereof in respect of which the Stock
Appreciation Right is then being exercised.

     (c) Amount of Payment. On exercise of a Stock Appreciation Right, a Grantee
shall be entitled to receive an amount equal to the product of (i) the amount by
which the Fair Market Value of a share of Stock on the date of exercise of the
Stock Appreciation Right exceeds the option price per share specified in the
related Incentive Stock Option and (ii) the number of shares of Stock in respect
of which the Stock Appreciation Right shall have been exercised.

     (d) Form of Payment. The Committee shall have the sole discretion either
(i) to determine the form in which payment in settlement of a Stock Appreciation
Right will be made (i.e., cash, Stock or any combination thereof), or (ii) to
consent to or disapprove the election by the Grantee to receive cash in full or
partial settlement of the Stock Appreciation Right, such consent or disapproval
to be given at any time after the election to which it relates. If settlement of
a Stock Appreciation Right, or portion thereof, is to be made in the form of
Stock, the number of shares of Stock to be distributed shall be the largest
whole number obtained by dividing the cash sum otherwise distributable in
respect of such settlement by the Fair Market Value of a share of Stock on the
date of exercise of the Stock Appreciation Right. The value of fractional shares
of Stock shall be paid in cash.

     (e) Effect of Exercise of Right or Related Option. If the related Incentive
Stock Option is exercised in whole or in part, then the Stock Appreciation Right
with respect to the 


                                       5
<PAGE>


Stock purchased pursuant to such exercise (but not with respect to any
unpurchased Stock) shall be terminated as of the date of exercise if such Stock
Appreciation Right is not exercised on such date.

     (f) Non-transferability. A Stock Appreciation Right shall not be
transferable or assignable by the Grantee other than by will or the laws of
descent and distribution, and shall be exercisable during the Grantee's lifetime
only by the Grantee.

     (g) Termination of Employment. If the Grantee ceases to be an Employee of
the Corporation for any reason, each outstanding Stock Appreciation Right shall
be exercisable for such period and to such extent as the related Incentive Stock
Option or portion thereof.

connection with the grant of a Non-Qualified Stock Option or unexercised portion
thereof held by the Grantee at any time and from time to time during the term
thereof. Each Stock Appreciation Right shall be subject to such terms and
conditions not inconsistent with the provisions of this Part III as shall be
determined by the Committee and included in the agreement relating to such Stock
Appreciation Right, subject in any event, however, to the following terms and
conditions of this Section 4. Each Stock Appreciation Right may include
limitations as to the time when such Stock Appreciation Right becomes
exercisable and when it ceases to be exercisable that are more


                                        7
<PAGE>


restrictive than the limitations on the exercise of the Non-Qualified Stock
Option to which it relates.

     (b) Exercise. No Stock Appreciation Right shall be exercisable with respect
to such related Non-Qualified Stock Option or portion thereof unless such
Non-Qualified Stock Option or portion shall itself be exercisable at that time.
A Stock Appreciation Right shall be exercised only upon surrender of the related
Non-Qualified Stock Option or portion thereof in respect of which the Stock
Appreciation Right is then being exercised.

     (c) Amount of Payment. On exercise of a Stock Appreciation Right, a Grantee
shall be entitled to receive an amount equal to the product of (i) the amount by
which the Fair Market Value of a share of Stock on the date of exercise of the
Stock Appreciation Right exceeds the option price per share specified in the
related Non-Qualified Stock Option and (ii) the number of shares of Stock in
respect of which the Stock Appreciation Right shall have been exercised.

     (d) Form of Payment. The Committee shall have the sole discretion either
(i) to determine the form in which payment in settlement of a Stock Appreciation
Right will be made (i.e., cash, Stock or any combination thereof), or (ii) to
consent to or disapprove the election by the Grantee to receive cash in full or
partial settlement of the Stock Appreciation Right, such consent or disapproval
to be given at any time after the election to which it relates. If settlement of
a Stock Appreciation Right, or portion thereof, is to be made in the form of
Stock, the number of shares of Stock to be distributed shall be the largest
whole number obtained by dividing the cash sum otherwise distributable in
respect of such settlement by the Fair Market Value of a share of Stock on the
date of exercise of the Stock Appreciation Right. The value of fractional shares
shall be paid in cash.

     (e) Effect of Exercise of Right or Related Option. If the related
Non-Qualified Stock Option is exercised in whole or in part, then the Stock
Appreciation Right with respect to the Stock purchased pursuant to such exercise
(but not with respect to any unpurchased Stock) shall be terminated as of the
date of exercise if such Stock Appreciation Right is not exercised on such date.

     (f) Non-transferability. A Stock Appreciation Right shall not be
transferable or assignable by the Grantee other than by will or the laws of
descent and distribution, and shall be exercisable during the Grantee's lifetime
only by the Grantee.

     (g) Termination of Employment. If the Grantee ceases to be an Employee,
Director or Consultant of the Corporation for any reason, each outstanding Stock
Appreciation Right shall be exercisable for such period and to such extent as
the related Non-Qualified Stock Option or portion thereof.

2. Adjustment Provisions.

     (a) In the event that a dividend shall be declared upon the Stock payable
in shares of the Corporation's common stock, the number of shares of Stock then
subject to any Stock Option or Stock Award outstanding under the Plan and the
number of shares reserved for the grant of Stock Options or Stock Awards
pursuant to the Plan shall be adjusted by adding to each such share the number
of shares which would be distributable in respect thereof if such shares had
been outstanding on the date fixed for determining the shareholders of the
Corporation entitled to receive such share dividend.

     (b) If the shares of Stock outstanding are changed into or exchanged for a
different number or class or other securities of the Corporation or of another
corporation, whether through split-up, merger, consolidation, reorganization,
reclassification or recapitalization then there shall be substituted for each
share of Stock subject to any such Stock Option or Stock Award and for each
share of Stock reserved for the grant of Stock Options or Stock Awards pursuant

in this Section 2, in the number or kind of outstanding shares of Stock or of
any shares or other securities into which such shares shall have been changed or
for which they shall have been exchanged, then if the Board shall, in its sole
discretion, determine that such change equitably requires an adjustment in the
number or kind of shares theretofore reserved for the grant of Stock Options or
Stock Awards pursuant to the Plan and of the shares then subject to Stock
Options or Stock Awards, such adjustment shall be made by the Board and shall be
effective and binding for all purposes of the Plan and of each Stock Option and

pursuant to this Section 2 and the number of outstanding Stock Appreciation
Rights, shall be adjusted, changed or exchanged in the same manner as related
Stock Options.

this Section 2, the option price set forth in each outstanding Stock Option for
each share covered thereby prior to such substitution or adjustment will be the
option price for all shares or other securities which shall have been
substituted for such share or to which such share shall have been adjusted
pursuant to this Section 2, and the price per share shall be adjusted
accordingly.

     (f) No adjustment or substitution provided for in this Section 2 shall
require the Corporation to sell a fractional share, and the total substitution
or adjustment with respect to each outstanding Stock Option shall be limited

     absolute discretion upon the advice of counsel, deem necessary or
     advisable; and

subject to any applicable tax, community property, or other statutes or
regulations of the United States or of any state having jurisdiction thereof.
The Grantee may be required to pay to the Corporation the amount of any
withholding taxes which the Corporation is required to withhold with respect to
a Stock Option or its exercise or a Stock Award. In the event that such payment
is not made when due, the Corporation shall have the right to deduct, to the
extent permitted by law, from any payment of any kind otherwise due to such
person all or part of the amount required to be withheld.

     (g) In the case of a grant of a Stock Option or Stock Award to any Employee
of a subsidiary of the Corporation, the Corporation may, if the Committee so
directs, issue or transfer 


                                       13

the shares, if any, covered by the Stock Option or Stock Award to the
subsidiary, for such lawful consideration as the Committee may specify, upon the
condition or understanding that the subsidiary will transfer the shares to the
Employee in accordance with the terms of the Stock Option or Stock Award
specified by the Committee pursuant to the provisions of the Plan. For purposes
of this Section, a subsidiary shall mean any subsidiary corporation of the
Corporation as defined in Section 424 of the Code.

Option or grant of a Stock Award shall not be deemed for any purpose to be, or
have rights as, a shareholder of the Corporation by virtue of such exercise,
except to the extent a stock certificate is issued therefor and then only from
the date such certificate is issued. No adjustments shall be made for dividends
or distributions or other rights for which the record date is prior to the date
such stock certificate is issued. The Corporation shall issue any stock
certificates required to be issued in connection with the exercise of a Stock
Option with reasonable promptness after such exercise.

     (i) The grant or exercise of Stock Options granted under the Plan or the
grant of a Stock Award under the Plan shall be subject to, and shall in all
respects comply with, applicable law relating to such grant or exercise, or to
the number of shares of Stock which may be beneficially owned or held by any
Grantee.

seeking  indemnification  hereunder were acting within the  reasonable  scope of

faith. The representations and warranties contained herein shall be binding upon
the Purchaser's heirs,  executors,  administrators,  trustees,  successors,  and

B. Sale or Transfer of Shares; Legend

     (a) The Shares and the Registerable  Shares and shares issued in respect of

either (i) they first shall have been  registered  under the Securities  Act, or
(ii) the  Company  first  shall  have been  furnished  with an  opinion of legal
counsel, reasonably satisfactory to the Company, to the effect that such sale or
transfer is exempt from the registration requirements of the Securities Act.

     (b) Each certificate  representing  the Shares and the Registrable  Shares,
and shares  issued in respect of the Shares and the  Registrable  Shares,  shall
bear a legend substantially in the following form:

          "The shares  represented by this  certificate have not been registered
          under the Securities Act of 1933, as amended,  and may not be offered,
          sold or otherwise  transferred or pledged unless and until such shares
          are  registered  under such Act or an  opinion  of counsel  reasonably
          satisfactory  to the  Company  is  obtained  to the  effect  that such
          registration is not required."

     The foregoing  legend shall be removed from the  certificates  representing
any Registrable  Shares,  at the request of the holder thereof,  at such time as
they become  eligible for resale  pursuant to Rule 144(k)  under the  Securities
Act.

C. Registration Rights

     1. Incidental  Registration Rights. (a) If the Company at any time proposes
for any reason to register  any of its  securities  under the Act (other than in
connection  with its Initial  Public  Offering  or  pursuant  to a  registration
statement on Forms S-4, S-8 or similar or successor or another form which is not
available for  registering  Registrable  Securities for sale to the public),  it
shall each such time promptly give written  notice to all Holders of Registrable
Securities  of its  intention  so to do, and,  upon the written  request,  given
within 10 days after receipt of any such notice,  of such Holder to register any
Registrable  Securities,  which request shall specify the number of  Registrable
Securities  intended to be sold or  disposed of by such  Holders and shall state
the  intended  method of  disposition  of such  Registrable  Securities  by such
Holders,  the Company  shall use its best efforts to cause all such  Registrable
Securities  to be  registered  under the Act as  required  to permit the sale or
other  disposition  (in  accordance  with  the  intended  methods  thereof,   as
aforesaid) by such Holders.  Notwithstanding  the  foregoing,  the Company shall
have the right to  withdraw  such  registration  statement,  if so  required  by
prudent business judgment, provided it shall reimburse the persons who indicated
their intention to include Registrable  Securities therein for the out-of-pocket
expenses   reasonably   incurred  by  such  persons  in  connection   therewith.
"Registrable  Securities",  for  purposes of this  Section  6(c),  means (i) the
Shares  and (ii) any  shares of Common  Stock  issued as (or  issuable  upon the
conversion or exercise of any warrant,  right or other  security which is issued
as) a dividend or other  distribution with respect to, or in exchange for, or in
replacement of, any of such Shares.


<PAGE>


     (b) In the event that the proposed registration by the Company is, in whole
or in part, an underwritten  public offering of securities of the Company (other
than  the  Initial  Public  Offering  as to  which  the  Holder  shall  have  no
registration  rights  under this  Section  6(c)),  any request  pursuant to this
Section 6 to register  may specify  that the  Registrable  Securities  are to be
included in the  underwriting (i) on the same terms and conditions as the shares
of Common Stock, if any,  otherwise being sold through  underwriters  under such
registration  or (ii) on terms  and  conditions  comparable  to  those  normally
applicable to offerings of common stock in reasonably  similar  circumstances in
the event that no shares of Common Stock other than  Registrable  Securities are
being sold through underwriters under such registration; provided, however, that
if the managing underwriter determines and advises in writing that the inclusion
of all Registrable Securities proposed to be included in the underwritten public
offering and other issued and outstanding  shares of Common Stock proposed to be
included  therein by persons other than holders of Registrable  Securities  (the
"Other  Shares")  would   interfere  with  the  successful   marketing  of  such
securities,  then the number of Registrable Securities and Other Shares shall be
reduced pro rata among the holders of  Registrable  Securities and Other Shares,
as necessary.

     2. Demand  Registration.  At any time after the Company becomes eligible to
file a  Registration  Statement on Form S-3 (or any  successor  form relating to
secondary  offerings),  a Holder  holding in the  aggregate  at least 25% of the
Registrable  Shares  may  request  the  Company,   in  writing,  to  effect  the
registration  on Form S-3 (or such  successor  form).  Upon  receipt of any such
request,  the  Company  shall  promptly  give  written  notice of such  proposed
registration to all Holders. Such Holders shall have the right by giving written
notice to the Company within 30 days after the Company  provides its notice,  to
elect to have included in such registration such of their Registrable  Shares as
such  Holders  may request in such notice of  Election.  Thereupon,  the Company
shall,  as  expeditiously  as  possible,  use its best  efforts  to  effect  the
registration  on Form S-3, or such  successor  form, of all  Registrable  Shares
which the Company has been requested to register.

     3.  Preparation  and  Filing.  If and  whenever  the  Company  is  under an
obligation  pursuant  to the  provisions  of this  Section  6(c) to use its best
efforts to effect the  registration of any Registrable  Securities,  the Company
shall, as expeditiously as practicable:

     (a) prepare and file with the SEC a registration  statement with respect to
such securities and use its best efforts to cause such registration statement to
become and remain effective;

     (b) prepare and file with the SEC such  amendments and  supplements to such
registration  statements and the prospectus used in connection  therewith as may
be necessary to keep such  registration  statement  effective  for at least nine
months and to comply with the  provisions of the  Securities Act with respect to
the sale or other  disposition  of all  Registrable  Securities  covered by such
registration statement;

     (c) furnish to each seller such number of copies of a summary prospectus or
other  prospectus,  including a preliminary  prospectus,  in conformity with the
requirements  of the Securities Act, and such other documents as such seller may
reasonably  request in order to facilitate the public sale or other  disposition
of such Registrable Securities;

     (d) use its best efforts to register or qualify the Registrable  Securities
covered by such registration  statement under the securities or blue sky laws of
such jurisdictions as each


<PAGE>


such seller shall reasonably request (provided,  however, that the Company shall
not be  required to consent to general  service of process  for all  purposes or
qualify to do business in any  jurisdiction  where it is not then qualified) and
do any and all  other  acts or  things  which  may be  reasonably  necessary  or
advisable  to  enable  such  seller  to  consummate  the  public  sale or  other
disposition in such jurisdictions of such securities; and

     (e)  notify  each  seller  of  Registerable   Securities  covered  by  such
registration statement at any time when a prospectus relating thereto covered by
such registration statement is required to be delivered under the Securities Act
within the  appropriate  period  mentioned in clause (b) of this ss.8.3,  of the
happening  of any  event as a result of which the  prospectus  included  in such
registration  statement,  as then in effect,  includes an untrue  statement of a
material fact or omits to state a material fact required to be stated therein or
necessary  to make the  statements  therein not  misleading  in the light of the
circumstances  then  existing,  and at the request of such  seller,  prepare and
furnish to such seller a reasonable  number of copies of a  supplement  to or an
amendment  of  such  prospectus  as may be  necessary  so  that,  as  thereafter
delivered  to the  purchasers  of such  securities,  such  prospectus  shall not
include an untrue  statement of a material fact or omit to state a material fact
required to be stated  therein or necessary to make the  statements  therein not
misleading in the light of the circumstances then existing.

     4. Registration  Expenses.  All Registration Expenses incurred in complying
with this Section 6(c) shall be paid for by the Company.

     5.  Indemnification.  In the  event  of  any  registration  of  Registrable
Securities  under the  Securities  Act  pursuant to this  Section  6(c) or other
registration or qualification thereof pursuant to Section 6(c)(3)(d) hereof, the
Company shall enter into an indemnity  agreement with the sellers of Registrable
Securities in customary form relating thereto.

     6.  Assignment.  The rights to cause the  Company to  register  Registrable
Securities  pursuant  to this  Section  6 may be  assigned  by a  Holder  to any
transferee or assignee of Registrable Securities upon the transfer or assignment
of all Registrable  Securities held by such Holder or a minimum of 20% of shares
of such Registrable Securities; provided that the Company is notified in writing
of such transfer,  the proposed transferee or assignee agrees to be bound by the
provisions of this Subscription Agreement.

7. ENTIRE AGREEMENT

     This Agreement contains the entire understanding between the parties hereto
and supersedes any prior  understanding  and agreements  between them respecting
the subject matter of this Agreement.

8. GOVERNING LAW

respects,  in  accordance  with the  internal  laws of the  State of  California
applicable to contracts made and to be performed  wholly therein,  except to the
extent  that by its terms the General  Corporation  Law of the State of Delaware

2. ACKNOWLEDGEMENT

capitalized  term used herein will have the meaning for purposes hereof assigned
to such term in the Memorandum or the Notes.

3. ACCEPTANCE

     The Purchaser  understands that this Agreement  represents one of a limited
number  of  subscriptions  for the  Notes  of the  Company  being  presented  to

Regulation D ("Regulation D") promulgated  under the Securities Act of 1933 (the

that this  Agreement  may be  accepted or rejected by the Company in whole or in
part, in the sole and absolute discretion of the Company,  and if accepted,  the

such representations and warranties.

4. REPRESENTATIONS AND WARRANTIES

The Purchaser hereby represents and warrants to the Company as follows:

     (a) The Purchaser is relying  solely upon the  Memorandum,  the  Appendices
thereto,  and independent  investigations  made by him or his representatives in
making his decision to purchase the Notes  described  herein.  The Purchaser has
not been  furnished any sales  literature or offering  other than the Memorandum
and the information referred to therein.

     (b) The  Purchaser  understands  that the  Notes and  Shares  have not been
registered under the Securities Act or any state securities acts, in reliance on
exemptions for private offerings under the Securities Act and such state acts.


<PAGE>


     (c) The Notes for which the Purchaser  hereby  subscribes and the Shares to
be issued to the Purchaser are being  acquired  solely for his own account,  for
investment,  and  are not  being  purchased  with a view  to or for the  resale,
distribution,  subdivision or fractionalization thereof; he has no present plans
to enter into any such contract, undertaking, agreement or arrangement. In order
to induce the Company to issue and sell the Notes  subscribed  for hereby to the
Purchaser,  it is agreed that the Company will have no  obligation  to recognize
the ownership,  beneficial or otherwise,  of such Notes and Shares by anyone but
the Purchaser.

     (d) The Purchaser  has received,  completed and returned to the Company the
Investor  Questionnaire  relating to his general ability to bear the risks of an
investment  in the  Company  and his  suitability  as an  investor  in a private
offering,  and the Purchaser  hereby  affirms the  correctness of his answers in
such Questionnaire.

     (e) The  Purchaser  acknowledges  and is aware that the Company has minimal
assets and operating history and that the Notes are speculative investments.

     (f) The  Purchaser  acknowledges  and is aware that  there are  substantial
restrictions  on the  transferability  of the  Notes and  Shares;  the Notes and
Shares will not be, and  investors in the Company have no rights  (other than to
the  limited  extent set forth  below) to require  that the Notes and Shares be,
registered  under the  Securities  Act;  there will be no public  market for the
Notes  and  Shares;  the  Purchaser  will  not be able to avail  himself  of the
provisions of Rule 144 adopted by the Securities and Exchange  Commission  under
the  Securities  Act with respect to the resale of the Notes and will be able to
avail  himself of the  provisions of such Rule 144 with respect to the resale of
the Shares only under the circumstances  set forth thereunder;  and accordingly,
that he may have to hold the Notes and Shares  indefinitely  and that it may not
be possible for him to liquidate his investment in the Company.

     (g) The Purchaser (i) has adequate means of providing for his current needs
and possible  personal  contingencies,  and he has no need for  liquidity of his
investment in the Company;  (ii) has a net worth  sufficient to bear the risk of
losing his entire  investment;  (iii) can bear the  economic  risk of losing his
entire  investment  herein;  and (iv)  does not have an  overall  commitment  to
non-readily  marketable  investments which is  disproportionate to his net worth
and the investment  subscribed for herein will not cause such overall commitment
to become excessive.

     (h)  If the  Purchaser  is an  individual,  he  warrants  that  he is  over
twenty-one  (21) years of age; and if the Purchaser is a  corporation,  trust or
partnership  the Purchaser  warrants that it is  authorized  and otherwise  duly
qualified to hold investments in the Company.

B. Sale or Transfer of Shares; Legend

     (a) The Shares and the Registerable  Shares and shares issued in respect of
the Shares or the  Registrable  Shares shall not be sold or  transferred  unless
either (i) they first shall have been  registered  under the Securities  Act, or
(ii) the  Company  first  shall  have been  furnished  with an  opinion of legal
counsel, reasonably satisfactory to the Company, to the effect that such sale or
transfer is exempt from the registration requirements of the Securities Act.

     (b) Each certificate  representing  the Shares and the Registrable  Shares,
and shares  issued in respect of the Shares and the  Registrable  Shares,  shall
bear a legend substantially in the following form:

     "The shares  represented by this certificate have not been registered under
     the  Securities  Act of 1933, as amended,  and may not be offered,  sold or
     otherwise   transferred  or  pledged  unless  and  until  such  shares  are
     registered under such Act or an opinion of counsel reasonably  satisfactory
     to the  Company is obtained  to the effect  that such  registration  is not
     required."

     The foregoing  legend shall be removed from the  certificates  representing
any Registrable  Shares,  at the request of the holder thereof,  at such time as
they become  eligible for resale  pursuant to Rule 144(k)  under the  Securities
Act.

C. Registration Rights

     1. Incidental  Registration Rights. (a) If the Company at any time proposes
for any reason to register  any of its  securities  under the Act (other than in
connection  with its Initial  Public  Offering  or  pursuant  to a  registration
statement on Forms S-4, S-8 or similar or successor or another form which is not
available for  registering  Registrable  Securities for sale to the public),  it
shall each such time promptly give written  notice to all Holders of Registrable
Securities  of its  intention  so to do, and,  upon the written  request,  given
within 10 days after receipt of any such notice,  of such Holder to register any
Registrable  Securities,  which request shall specify the number of  Registrable
Securities  intended to be sold or  disposed of by such  Holders and shall state
the  intended  method of  disposition  of such  Registrable  Securities  by such
Holders,  the Company  shall use its best efforts to cause all such  Registrable
Securities  to be  registered  under the Act as  required  to permit the sale or
other  disposition  (in  accordance  with  the  intended  methods  thereof,   as
aforesaid) by such Holders.  Notwithstanding  the  foregoing,  the Company shall
have the right to  withdraw  such  registration  statement,  if so  required  by
prudent business judgment, provided it shall reimburse the persons who indicated
their intention to include Registrable  Securities therein for the out-of-pocket
expenses   reasonably   incurred  by  such  persons  in  connection   therewith.
"Registrable  Securities",  for  purposes of this  Section  6(c),  means (i) the
Shares  and (ii) any  shares of Common  Stock  issued as (or  issuable  upon the
conversion or exercise of any warrant,  right or other  security which is issued
as) a dividend or other  distribution with respect to, or in exchange for, or in
replacement of, any of such Shares.


<PAGE>


     (b) In the event that the proposed registration by the Company is, in whole
or in part, an underwritten  public offering of securities of the Company (other
than  the  Initial  Public  Offering  as to  which  the  Holder  shall  have  no
registration  rights  under this  Section  6(c)),  any request  pursuant to this
Section 6 to register  may specify  that the  Registrable  Securities  are to be
included in the  underwriting (i) on the same terms and conditions as the shares
of Common Stock, if any,  otherwise being sold through  underwriters  under such
registration  or (ii) on terms  and  conditions  comparable  to  those  normally
applicable to offerings of common stock in reasonably  similar  circumstances in
the event that no shares of Common Stock other than  Registrable  Securities are
being sold through underwriters under such registration; provided, however, that
if the managing underwriter determines and advises in writing that the inclusion
of all Registrable Securities proposed to be included in the underwritten public
offering and other issued and outstanding  shares of Common Stock proposed to be
included  therein by persons other than holders of Registrable  Securities  (the
"Other  Shares")  would   interfere  with  the  successful   marketing  of  such
securities,  then the number of Registrable Securities and Other Shares shall be
reduced pro rata among the holders of  Registrable  Securities and Other Shares,
as necessary.

     2. Demand  Registration.  At any time after the Company becomes eligible to
file a  Registration  Statement on Form S-3 (or any  successor  form relating to
secondary  offerings),  a Holder  holding in the  aggregate  at least 25% of the
Registrable  Shares  may  request  the  Company,   in  writing,  to  effect  the
registration  on Form S-3 (or such  successor  form).  Upon  receipt of any such
request,  the  Company  shall  promptly  give  written  notice of such  proposed
registration to all Holders. Such Holders shall have the right by giving written
notice to the Company within 30 days after the Company  provides its notice,  to
elect to have included in such registration such of their Registrable  Shares as
such  Holders  may request in such notice of  Election.  Thereupon,  the Company
shall,  as  expeditiously  as  possible,  use its best  efforts  to  effect  the
registration  on Form S-3, or such  successor  form, of all  Registrable  Shares
which the Company has been requested to register.

     3.  Preparation  and  Filing.  If and  whenever  the  Company  is  under an
obligation  pursuant  to the  provisions  of this  Section  6(c) to use its best
efforts to effect the  registration of any Registrable  Securities,  the Company
shall, as expeditiously as practicable:

     (a) prepare and file with the SEC a registration  statement with respect to
such securities and use its best efforts to cause such registration statement to
become and remain effective;

     (b) prepare and file with the SEC such  amendments and  supplements to such
registration  statements and the prospectus used in connection  therewith as may
be necessary to keep such  registration  statement  effective  for at least nine
months and to comply with the  provisions of the  Securities Act with respect to
the sale or other  disposition  of all  Registrable  Securities  covered by such
registration statement;

     (c) furnish to each seller such number of copies of a summary prospectus or
other  prospectus,  including a preliminary  prospectus,  in conformity with the
requirements  of the Securities Act, and such other documents as such seller may
reasonably  request in order to facilitate the public sale or other  disposition
of such Registrable Securities;

     (d) use its best efforts to register or qualify the Registrable  Securities
covered by such registration  statement under the securities or blue sky laws of
such jurisdictions as each


<PAGE>


such seller shall reasonably request (provided,  however, that the Company shall
not be  required to consent to general  service of process  for all  purposes or
qualify to do business in any  jurisdiction  where it is not then qualified) and
do any and all  other  acts or  things  which  may be  reasonably  necessary  or
advisable  to  enable  such  seller  to  consummate  the  public  sale or  other
disposition in such jurisdictions of such securities; and

     (e)  notify  each  seller  of  Registerable   Securities  covered  by  such
registration statement at any time when a prospectus relating thereto covered by
such registration statement is required to be delivered under the Securities Act
within the  appropriate  period  mentioned in clause (b) of this ss.8.3,  of the
happening  of any  event as a result of which the  prospectus  included  in such
registration  statement,  as then in effect,  includes an untrue  statement of a
material fact or omits to state a material fact required to be stated therein or
necessary  to make the  statements  therein not  misleading  in the light of the
circumstances  then  existing,  and at the request of such  seller,  prepare and
furnish to such seller a reasonable  number of copies of a  supplement  to or an
amendment  of  such  prospectus  as may be  necessary  so  that,  as  thereafter
delivered  to the  purchasers  of such  securities,  such  prospectus  shall not
include an untrue  statement of a material fact or omit to state a material fact
required to be stated  therein or necessary to make the  statements  therein not
misleading in the light of the circumstances then existing.

     4. Registration  Expenses.  All Registration Expenses incurred in complying
with this Section 6(c) shall be paid for by the Company.

     5.  Indemnification.  In the  event  of  any  registration  of  Registrable
Securities  under the  Securities  Act  pursuant to this  Section  6(c) or other
registration or qualification thereof pursuant to Section 6(c)(3)(d) hereof, the
Company shall enter into an indemnity  agreement with the sellers of Registrable
Securities in customary form relating thereto.

     6.  Assignment.  The rights to cause the  Company to  register  Registrable
Securities  pursuant  to this  Section  6 may be  assigned  by a  Holder  to any
transferee or assignee of Registrable Securities upon the transfer or assignment
of all Registrable  Securities held by such Holder or a minimum of 20% of shares
of such Registrable Securities; provided that the Company is notified in writing
of such transfer,  the proposed transferee or assignee agrees to be bound by the
provisions of this Subscription Agreement.

7. ENTIRE AGREEMENT

     This Agreement contains the entire understanding between the parties hereto
and supersedes any prior  understanding  and agreements  between them respecting
the subject matter of this Agreement.

8. GOVERNING LAW

respects,  in  accordance  with the  internal  laws of the  State of  California
applicable to contracts made and to be performed  wholly therein,  except to the
extent  that by its terms the General  Corporation  Law of the State of Delaware

2. ACKNOWLEDGEMENT

         The Purchaser hereby acknowledges receipt of a copy of the Confidential

concerning the Company and offering of the Notes. Unless otherwise stated, every
capitalized term used herein will have the meaning for purposes hereof assigned
to such term in the Memorandum or the Notes.

3. ACCEPTANCE

         The Purchaser understands that this Agreement represents one of a
limited number of subscriptions for the Notes of the Company being presented to

Purchaser acknowledges that the Company is relying upon the representations and
warranties of the Purchaser set forth herein and in the accompanying Investor

of any circumstance or event which could affect the accuracy or completeness of
such representations and warranties.

4. REPRESENTATIONS AND WARRANTIES

The Purchaser hereby represents and warrants to the Company as follows:

         (a) The Purchaser is relying solely upon the Memorandum, the Appendices
thereto, and independent investigations made by him or his representatives in
making his decision to purchase the Notes described herein. The Purchaser has
not been furnished any sales literature or offering other than the Memorandum
and the information referred to therein.

<PAGE>

         (b) The Purchaser understands that the Notes and Shares have not been
registered under the Securities Act or any state securities acts, in reliance on
exemptions for private offerings under the Securities Act and such state acts.

         (c) The Notes for which the Purchaser hereby subscribes and the Shares
to be issued to the Purchaser are being acquired solely for his own account, for
investment, and are not being purchased with a view to or for the resale,
distribution, subdivision or fractionalization thereof; he has no present plans
to enter into any such contract, undertaking, agreement or arrangement. In order
to induce the Company to issue and sell the Notes subscribed for hereby to the
Purchaser, it is agreed that the Company will have no obligation to recognize
the ownership, beneficial or otherwise, of such Notes and Shares by anyone but
the Purchaser.

         (d) The Purchaser has received, completed and returned to the Company
the Investor Questionnaire relating to his general ability to bear the risks of
an investment in the Company and his suitability as an investor in a private
offering, and the Purchaser hereby affirms the correctness of his answers in
such Questionnaire.

         (e) The Purchaser acknowledges and is aware that the Company has
minimal assets and operating history and that the Notes are speculative
investments.

         (f) The Purchaser acknowledges and is aware that there are substantial
restrictions on the transferability of the Notes and Shares; the Notes and
Shares will not be, and investors in the Company have no rights (other than to
the limited extent set forth below) to require that the Notes and Shares be,
registered under the Securities Act; there will be no public market for the
Notes and Shares; the Purchaser will not be able to avail himself of the
provisions of Rule 144 adopted by the Securities and Exchange Commission under
the Securities Act with respect to the resale of the Notes and will be able to
avail himself of the provisions of such Rule 144 with respect to the resale of
the Shares only under the circumstances set forth thereunder; and accordingly,
that he may have to hold the Notes and Shares indefinitely and that it may not
be possible for him to liquidate his investment in the Company.

         (g) The Purchaser (i) has adequate means of providing for his current
needs and possible personal contingencies, and he has no need for liquidity of
his investment in the Company; (ii) has a net worth sufficient to bear the risk
of losing his entire investment; (iii) can bear the economic risk of losing his
entire investment herein; and (iv) does not have an overall commitment to
non-readily marketable investments which is disproportionate to his net worth
and the investment subscribed for herein will not cause such overall commitment
to become excessive.

         (h) If the Purchaser is an individual, he warrants that he is over
twenty-one (21) years of age; and if the Purchaser is a corporation, trust or
partnership the Purchaser warrants that it is authorized and otherwise duly
qualified to hold investments in the Company.

5. INDEMNIFICATION

         The Purchaser hereby indemnifies the Company and the Members of the
Board of Directors and the officers of the Company and all of their affiliates,
agents and controlling persons, and each of them, and agrees to hold them, and
each of them, harmless from and against any and all loss, damage, claim,
liability or expense (including reasonable attorneys' fees and expenses and

reason of, or in connection with any misrepresentation or breach of any
warranty, agreement or covenant made or undertaken in this Agreement, any
Investor Questionnaire or otherwise in connection with the sale or distribution
by the Purchaser of the Notes and Shares purchased by, or otherwise issued to,

the Purchaser hereunder. Such Shares shall be subject to the terms and
conditions set forth in this Section 6.

B.       Sale or Transfer of Shares; Legend

         (a) The Shares and the Registerable Shares and shares issued in respect
of the Shares or the Registrable Shares shall not be sold or transferred unless
either (i) they first shall have been registered under the Securities Act, or
(ii) the Company first shall have been furnished with an opinion of legal
counsel, reasonably satisfactory to the Company, to the effect that such sale or
transfer is exempt from the registration requirements of the Securities Act.

         (b) Each certificate representing the Shares and the Registrable
Shares, and shares issued in respect of the Shares and the Registrable Shares,
shall bear a legend substantially in the following form:

         "The shares represented by this certificate have not been registered
         under the Securities Act of 1933, as amended, and may not be offered,
         sold or otherwise transferred or pledged unless and until such shares
         are registered under such Act or an opinion of counsel reasonably
         satisfactory to the Company is obtained to the effect that such
         registration is not required."

         The foregoing legend shall be removed from the certificates
representing any Registrable Shares, at the request of the holder thereof, at
such time as they become eligible for resale pursuant to Rule 144(k) under the
Securities Act.

C.       Registration Rights

         1. Incidental Registration Rights. (a) If the Company at any time
proposes for any reason to register any of its securities under the Act (other
than in connection with its Initial Public Offering or pursuant to a
registration statement on Forms S-4, S-8 or similar or successor or another form
which is not available for registering Registrable Securities for sale to the
public), it shall each such time promptly give written notice to all Holders of
Registrable Securities of its intention so to do, and, upon the written request,
given within 10 days after receipt of any such notice, of such Holder to
register any Registrable Securities, which request shall specify the number of
Registrable Securities intended to be sold or disposed of by such Holders and
shall state the intended method of disposition of such Registrable Securities by
such Holders, the Company shall use its best efforts to cause all such
Registrable Securities to be registered under the Act as required to permit the
sale or other disposition (in accordance with the intended methods thereof, as
aforesaid) by such Holders. Notwithstanding the foregoing, the Company shall
have the right to withdraw such registration statement, if so required by
prudent business judgment, provided it shall reimburse the persons who indicated
their intention to include Registrable Securities therein for the out-of-pocket
expenses reasonably incurred by such persons in connection therewith.
"Registrable Securities", for purposes of this Section 6(c), means (i) the
Shares and (ii) any shares of Common Stock issued as (or issuable upon the
conversion or exercise of any warrant, right or other security which is issued
as) a dividend or other distribution with respect to, or in exchange for, or in
replacement of, any of such Shares.

<PAGE>

         (b) In the event that the proposed registration by the Company is, in
whole or in part, an underwritten public offering of securities of the Company
(other than the Initial Public Offering as to which the Holder shall have no
registration rights under this Section 6(c)), any request pursuant to this
Section 6 to register may specify that the Registrable Securities are to be
included in the underwriting (i) on the same terms and conditions as the shares
of Common Stock, if any, otherwise being sold through underwriters under such
registration or (ii) on terms and conditions comparable to those normally
applicable to offerings of common stock in reasonably similar circumstances in
the event that no shares of Common Stock other than Registrable Securities are
being sold through underwriters under such registration; provided, however, that
if the managing underwriter determines and advises in writing that the inclusion
of all Registrable Securities proposed to be included in the underwritten public
offering and other issued and outstanding shares of Common Stock proposed to be
included therein by persons other than holders of Registrable Securities (the
"Other Shares") would interfere with the successful marketing of such
securities, then the number of Registrable Securities and Other Shares shall be
reduced pro rata among the holders of Registrable Securities and Other Shares,
as necessary.

         2. Demand Registration. At any time after the Company becomes eligible
to file a Registration Statement on Form S-3 (or any successor form relating to
secondary offerings), a Holder holding in the aggregate at least 25% of the
Registrable Shares may request the Company, in writing, to effect the
registration on Form S-3 (or such successor form). Upon receipt of any such
request, the Company shall promptly give written notice of such proposed
registration to all Holders. Such Holders shall have the right by giving written
notice to the Company within 30 days after the Company provides its notice, to
elect to have included in such registration such of their Registrable Shares as
such Holders may request in such notice of Election. Thereupon, the Company
shall, as expeditiously as possible, use its best efforts to effect the
registration on Form S-3, or such successor form, of all Registrable Shares
which the Company has been requested to register.

         3. Preparation and Filing. If and whenever the Company is under an
obligation pursuant to the provisions of this Section 6(c) to use its best
efforts to effect the registration of any Registrable Securities, the Company
shall, as expeditiously as practicable:

                  (a) prepare and file with the SEC a registration statement
with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective;

                  (b) prepare and file with the SEC such amendments and
supplements to such registration statements and the prospectus used in
connection therewith as may be necessary to keep such registration statement
effective for at least nine months and to comply with the provisions of the
Securities Act with respect to the sale or other disposition of all Registrable
Securities covered by such registration statement;

                  (c) furnish to each seller such number of copies of a summary
prospectus or other prospectus, including a preliminary prospectus, in
conformity with the requirements of the Securities Act, and such other documents
as such seller may reasonably request in order to facilitate the public sale or
other disposition of such Registrable Securities;

                  (d) use its best efforts to register or qualify the
Registrable Securities covered by such registration statement under the
securities or blue sky laws of such jurisdictions as each such seller shall
reasonably request (provided, however, that the Company shall not be required to
consent to general service of process for all purposes or qualify to do business
in any 



<PAGE>

jurisdiction where it is not then qualified) and do any and all other acts or 
things which may be reasonably necessary or advisable to enable such seller to
consummate the public sale or other disposition in such jurisdictions of such 
securities; and

                  (e) notify each seller of Registerable Securities covered by
such registration statement at any time when a prospectus relating thereto
covered by such registration statement is required to be delivered under the
Securities Act within the appropriate period mentioned in clause (b) of this
ss.8.3, of the happening of any event as a result of which the prospectus
included in such registration statement, as then in effect, includes an untrue
statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements therein not misleading in the
light of the circumstances then existing, and at the request of such seller,
prepare and furnish to such seller a reasonable number of copies of a supplement
to or an amendment of such prospectus as may be necessary so that, as thereafter
delivered to the purchasers of such securities, such prospectus shall not
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances then existing.

         4. Registration Expenses. All Registration Expenses incurred in
complying with this Section 6(c) shall be paid for by the Company.

         5. Indemnification. In the event of any registration of Registrable
Securities under the Securities Act pursuant to this Section 6(c) or other
registration or qualification thereof pursuant to Section 6(c)(3)(d) hereof, the
Company shall enter into an indemnity agreement with the sellers of Registrable
Securities in customary form relating thereto.

         6. Assignment. The rights to cause the Company to register Registrable
Securities pursuant to this Section 6 may be assigned by a Holder to any
transferee or assignee of Registrable Securities upon the transfer or assignment
of all Registrable Securities held by such Holder or a minimum of 20% of shares
of such Registrable Securities; provided that the Company is notified in writing
of such transfer, the proposed transferee or assignee agrees to be bound by the
provisions of this Subscription Agreement.

     WHEREAS, pursuant to the Agreement, Omega issued 225,000 shares of Common
Stock to each of Glovsky and Mayflower (individually, the "Glovsky Shares" or
the "Mayflower Shares," as the case may be, and collectively, the "Shares") and
placed the Shares in escrow (the "Escrow") pending completion of the services
required by the Agreement;

     WHEREAS, Omega and the Consultants desire to amend and restate the
Agreement in order to reflect more accurately the services required to be
rendered by each of Glovsky and Mayflower thereunder and to clarify the
conditions to the release of the Shares from the Escrow and to enter into this
Amended and Restated Consulting Agreement amending and restating the Agreement
in its entirety as provided herein.

     NOW, THEREFORE, in consideration of the premises, the mutual covenants and
agreements hereinafter set forth and for other good and valuable consideration,
the receipt, adequacy and sufficiency of which are hereby acknowledged, the
parties hereto covenant and agree as follows:

     1. GLOVSKY SERVICES. During the term of this Amended and Restated

whatsoever;  (ii) have any authority to make any agreement or commitment for any
other party or to incur  liability or obligation in any other party's name or on
his or its behalf;  or (iii) represent to third parties that any of them has any
right so to bind any other party hereto.

     7.  CONFIDENTIALITY.  Neither Consultant shall, either during the period of
his  consultancy  with Omega or  thereafter,  reveal or  disclose  to any person
outside  Omega  or use to his own  benefit,  any  proprietary  and  confidential

orthodontic  entity list of Omega or any patient list thereof or any proprietary
and confidential mailing or supplier list, whether or not made, developed and/or
conceived  by such  Consultant  or by  others in the  employ of Omega.  Upon the
termination  of such  Consultant's  consultancy in any manner or for any reason,
the  Consultant  shall  promptly  surrender  to Omega  all  copies of any of the
foregoing,  together with any other documents, 


                                       2
<PAGE>

materials,  data,  information and equipment belonging to or relating to Omega's
business and in his possession,  custody or control,  and such Consultant  shall
not  thereafter  retain or deliver to any other person,  any of the foregoing or
any summary or memorandum thereof.

      8. FURTHER  ASSURANCES.  If compliance with securities or other federal or
state  laws,  rules or  regulations,  or the rules and  regulations  of any self
regulatory  organization or other agency or organization  with jurisdiction over
one or more of the parties,  requires the  modification of all or any portion of

Mr. Robert Schulhof, President
Omega Orthodontics, Inc.

Acton, CA 93520

Dear Bob:

We are pleased to confirm our understanding of the nature and limitations of the
services we are to provide for Omega Orthodontics, Inc.

Edward M. Mulherin, CPA, Esquire will act as controller and interim chief
financial officer for the corporation until January 31, 1996 or otherwise agreed
upon. The range of services we are to provide include:

o    Review financial information for potential acquisition targets, convert to
     accrual based GAAP financials, as required. Prepare workpapers and
     supporting documentation for audit firm.

o    Participate in drafting IPO prospectus, resolve SEC issues and act as
     liaison between corporation and accounting firm.

o    Participate in drafting of projections and forecasts for public offering.

o    Review tax issues, prepare federal and state tax returns.

o    Document and implement corporate accounting software, as needed.

o    Assist with hiring of full-time CFO/controller.

We will not express an opinion on Omega Orthodontics, Inc.'s financial
statements or any elements, accounts or items thereof.



<PAGE>

We would discount our standard hourly rates as follows:

                        Standard Rate             Discount Fee
Partner (EMM)             $ 125                       $ 100
Manager                   $  80                       $  70
Staff                     $  60                       $  50

We would be willing to make the same investment in Omega Orthodontics, Inc. as
the Company's recently issued "bridge" financing. Based on initial discussions I
estimate that the time and billing required to perform the above services by
myself and my staff will be at least $50,000. We would be willing to defer
payment of this amount until the Company's initial public offering. In exchange,
we would receive a 15% return on the investment and stock options for 10,000
shares of the Company's stock. Any out-of-pocket costs for travel, etc. would be
aid as incurred. In addition, any billing over $50,000 would be paid as
incurred.

We appreciate the opportunity to assist you and believe this letter accurately
summarizes the significant terms of our engagement. If you have any questions,
please let us know. If you agree with the terms of our engagement as described
in this letter, please sign the enclosed copy and return it to us. If the need
for additional services arises, our agreement with you will be revised. It is
customary for us to enumerate these revisions in an addendum to this letter.

Very truly yours,

                                    EXHIBIT A


     Section 1. Definitions. For purposes of this Exhibit A, the following terms
shall have the meanings indicated:

     "Court" means the Court of Chancery of the State of Delaware, the court in
which the Proceeding in respect of which indemnification is sought by the
Consultant shall have been brought or is pending, or another court having
subject matter jurisdiction and personal jurisdiction over the parties.

     "Disinterested" describes any individual, whether or not that individual is
a director, officer, employee or agent of the corporation who is not and was not
and is not threatened to be made a party to the Proceeding in respect of which
indemnification, advancement of expenses or other action, is sought by the
Consultant.

     "Expenses" shall include, without limitation, all reasonable attorneys'
fees, retainers, court costs, transcript costs, fees of experts, witness fees,
travel expenses, duplicating costs, printing and binding costs, telephone
charges, postage, delivery service fees, and all other disbursements or expenses
of the types customarily incurred in connection with prosecuting, defending,
preparing to prosecute or defend, investigating or being or preparing to be a
witness in a Proceeding.

     "Good Faith" shall mean the Consultant having acted in good faith and in a
manner the Consultant reasonably believed to be in or not opposed to the best
interests of the corporation and, with respect to any Proceeding which is
criminal in nature, having had no reasonable cause to believe the Consultant's
conduct was unlawful.

     "Independent Counsel" means a law firm, or a member of a law firm, that is
experienced in matters of corporation law and may include law firms or members
thereof that are regularly retained by the corporation but not by any other
party to the Proceeding giving rise to a claim for indemnification hereunder.
Notwithstanding the foregoing, the term "Independent Counsel" shall not include
any person who, under the standards of professional conduct then prevailing and
applicable to such counsel, would have a conflict of interest in representing
either the corporation or the Consultant in an action to determine the
Consultant's rights under this Exhibit A.

     "Proceeding" includes any actual, threatened or completed action, suit,
arbitration, alternative dispute resolution mechanism, investigation (including
any internal corporate investigation), administrative hearing or any other
proceeding, whether civil, criminal, administrative or investigative, other than
one initiated by the Consultant, but including one initiated by the Consultant
for the purpose of enforcing the Consultant's rights under this Exhibit A to the
extent provided in Section 15 of this Exhibit A. "Proceeding" shall not include
any counterclaim brought by the Consultant other than one arising out of the
same transaction or occurrence that is the subject matter of the underlying
claim.

                                       7
<PAGE>

     Section 2. Right to Indemnification in General. The corporation shall
indemnify, and advance Expenses to the Consultant when the Consultant is, was or
is threatened to be made a party or is otherwise involved in any Proceeding, as
provided in this Exhibit A and to the fullest extent permitted by applicable law
in effect on the date hereof and to such greater extent as applicable law may
hereafter from time to time permit.

     The indemnification provisions in this Exhibit A shall be deemed to be a
contract between the corporation and the Consultant at any time while these
provisions as well as the relevant provisions of the Delaware General
Corporation Law are in effect, and any repeal or modification thereof shall not
affect any right or obligation then existing with respect to any state of facts
then or previously existing or any Proceeding previously or thereafter brought
or threatened based in whole or in part upon any such state of facts. Such a
contract right may not be modified retroactively without the consent of the
Consultant.

     Section 3. Proceedings Other Than Proceedings by or in the Right of the
Corporation. The Consultant shall be entitled to the rights of indemnification
provided in this Section 3 if, by reason of providing consulting services to the
corporation, the Consultant is, or is threatened to be made, a party to or is
otherwise involved in any Proceeding, other than a Proceeding by or in the right
of the corporation. The Consultant shall be indemnified against Expenses,
judgments, penalties, fines and amounts paid in settlement, actually and
reasonably incurred by or on behalf of the Consultant in connection with such
Proceeding or any claim, issue or matter therein, if the Consultant acted in
Good Faith.

     Section 4. Proceedings by or in the Right of the Corporation. The
Consultant shall be entitled to the rights of indemnification provided in this
Section 4 if, by reason of providing consulting services to the corporation, the
Consultant is, or is threatened to be made, a party to or is otherwise involved
in any Proceeding brought by or in the right of the corporation to procure a
judgment in its favor. The Consultant shall be indemnified against Expenses,
judgments, penalties, fines and amounts paid in settlement, actually and
reasonably incurred by such or on behalf of the Consultant in connection with
such Proceeding or any claim, issue or matter therein, if the Consultant acted
in Good Faith. Notwithstanding the foregoing, no such indemnification shall be
made in respect of any claim, issue or matter in such Proceeding as to which the
Consultant shall have been adjudged to be liable to the corporation if
applicable law prohibits such indemnification; provided, however, that, if
applicable law so permits, indemnification shall nevertheless be made by the
corporation in such event if and only to the extent that the Court which is
considering the matter shall so determine.

      Section 5. Indemnification of a Party Who is Wholly or Partly Successful.
Notwithstanding any other provision of this Exhibit A, to the extent that the
Consultant is, by reason of providing consulting services to the corporation, a
party to or is otherwise involved in and is successful, on the merits or
otherwise, in any Proceeding, the Consultant shall be indemnified to the maximum
extent permitted by law, against all Expenses, judgments, penalties, fines, and
amounts paid in settlement, actually and reasonably incurred by or on behalf of
the Consultant in connection therewith. If the Consultant is not wholly
successful in such Proceeding but is successful, on the merits or otherwise, as
to one or more but less than all claims, issues or matters in such Proceeding,
the corporation shall indemnify the Consultant to


                                       8
<PAGE>


the maximum extent permitted by law, against all Expenses, judgments, penalties,
fines, and amounts paid in settlement, actually and reasonably incurred by or on
behalf of the Consultant in connection with each successfully resolved claim,
issue or matter. For purposes of this Section 5 and without limitation, the
termination of any claim, issue or matter in such a Proceeding by dismissal,
with or without prejudice, shall be deemed to be a successful result as to such
claim, issue or matter.

     Section 6. Indemnification for Expenses of a Witness. Notwithstanding any
other provision of this Exhibit A, to the extent that the Consultant is, by
reason of providing consulting services to the corporation, a witness in any
Proceeding, the Consultant shall be indemnified against all Expenses actually
and reasonably incurred by or on behalf of the Consultant in connection
therewith.

     Section 7. Advancement of Expenses. Notwithstanding any provision to the
contrary in this Exhibit A, the corporation shall advance all reasonable
Expenses which, by reason of the Consultant providing consulting services to the
corporation, were incurred by or on behalf of the Consultant in connection with
any Proceeding, within twenty (20) days after the receipt by the corporation of
a statement or statements from the Consultant requesting such advance or
advances, whether prior to or after final disposition of such Proceeding. Such
statement or statements shall reasonably evidence the Expenses incurred by the
Consultant and shall include or be preceded or accompanied by an undertaking by
or on behalf of the Consultant to repay any Expenses if the Consultant shall be
adjudged to be not entitled to be indemnified against such Expenses. Any advance
and undertakings to repay made pursuant to this Section 7 shall be unsecured and
interest-free. Advancement of Expenses pursuant to this Section 7 shall not
require approval of the board of directors or the stockholders of the
corporation, or of any other person or body. The secretary of the corporation
shall promptly advise the Board in writing of the request for advancement of
Expenses, of the amount and other details of the advance and of the undertaking
to make repayment provided pursuant to this Section 7.

     Section 8. Notification and Defense of Claim. Promptly after receipt by the
Consultant of notice of the commencement of any Proceeding, the Consultant
shall, if a claim is to be made against the corporation under this Exhibit A,
notify the corporation of the commencement of the Proceeding. The omission of
such notice will not relieve the corporation from any liability which it may
have to the Consultant otherwise than under this Exhibit A. With respect to any
such Proceedings of which the Consultant has provided notice to the corporation:

     (a) The corporation will be entitled to participate in the defense at its
own expense.

     (b) Except as otherwise provided below, the corporation (jointly with any
other indemnifying party similarly notified) will be entitled to assume the
defense with counsel reasonably satisfactory to the Consultant. After notice
from the corporation to the Consultant of its election to assume the defense of
a suit, the corporation will not be liable to the Consultant under this Exhibit
A for any legal or other expenses subsequently incurred by the Consultant in
connection with the defense of the Proceeding other than reasonable costs of
investigation or as otherwise provided below.


                                       9
<PAGE>


     The Consultant shall have the right to employ its own counsel in such
Proceeding but the fees and expenses of such counsel incurred after notice from
the corporation of its assumption of the defense shall be at the expense of the
Consultant except as follows. The fees and expenses of counsel shall be at the
expense of the corporation if (i) the employment of counsel by the Consultant
has been authorized by the corporation, (ii) the Consultant shall have concluded
reasonably that there may be a conflict of interest between the corporation and
the Consultant in the conduct of the defense of such action and such conclusion
is confirmed in writing by the corporation's outside counsel regularly employed
by it in connection with corporate matters, or (iii) the corporation shall not
in fact have employed counsel to assume the defense of such Proceeding. The
corporation shall be entitled to participate in, but shall not be entitled to
assume the defense of, any Proceeding brought by or in the right of the
corporation or as to which the Consultant shall have made the conclusion
provided for in (ii) above and such conclusion shall have been so confirmed by
the corporation's said outside counsel.

     (c) Notwithstanding any provision of this Exhibit A to the contrary, the
corporation shall not be liable to indemnify the Consultant under this Exhibit A
for any amounts paid in settlement of any Proceeding effected without its
written consent. The corporation shall not settle any Proceeding or claim in any
manner which would impose any penalty, limitation or disqualification of the
Consultant for any purpose without the Consultant's written consent. Neither the
corporation nor the Consultant will unreasonably withhold their consent to any
proposed settlement.

     (d) If it is determined that the Consultant is entitled to indemnification
other than as afforded under subparagraph (b) above, payment to the Consultant
of the additional amounts for which the Consultant is to be indemnified shall be
made within ten (l0) days after such determination.

     Section 9. Procedures.

     (a) Method of Determination. A determination (as provided for by this
Exhibit A or if required by applicable law in the specific case) with respect to
the Consultant's entitlement to indemnification shall be made either (a) by the
board of directors by a majority vote of a quorum consisting of Disinterested
directors, or (b) in the event that a quorum of the board of directors
consisting of Disinterested directors is not obtainable or, even if obtainable,
such quorum of Disinterested directors so directs, by Independent Counsel in a
written determination to the board of directors, a copy of which shall be
delivered to the Consultant seeking indemnification, or (c) by the vote of the
holders of a majority of the corporation's capital stock outstanding at the time
entitled to vote thereon.

     (b) Initiating Request. The Consultant seeking indemnification under this
Exhibit A shall submit a Request for Indemnification, including such
documentation and information as is reasonably available to the Consultant and
is reasonably necessary to determine whether and to what extent the Consultant
is entitled to indemnification.


                                       10
<PAGE>


     (c) Presumptions. In making a determination with respect to entitlement to
indemnification hereunder, the person or persons or entity making such
determination shall presume that the Consultant is entitled to indemnification
under this Exhibit A.

     (d) Burden of Proof. The person or entity opposing the Consultant's claim
for indemnification shall have the burden of proof to overcome the presumption
described by Section 9(c) above in connection with the making by any person,
persons or entity of any determination contrary to that presumption.

     (e) Effect of Other Proceedings. The termination of any proceeding or of
any claim, issue or matter therein, by judgment, order, settlement of
conviction, or upon a plea of guilty or of nolo contendere or its equivalent,
shall not (except as otherwise expressly provided in this Exhibit A) of itself
adversely affect the right of the Consultant to indemnification or create a
presumption that the Consultant did not act in Good Faith.

     Section 10. Action by the Corporation. Any action, payment, advance
determination other than a determination made pursuant to Section 9,
authorization, requirement, grant of indemnification or other action taken by
the corporation pursuant to this Exhibit A shall be effected exclusively through
any Disinterested person so authorized by the board of directors of the
corporation, including the president or any vice president of the corporation.

     Section 11. Exclusivity. The rights to indemnification and to receive
advancement of Expenses as provided by this Exhibit A shall be and be deemed to
be the sole rights to which the Consultant shall be entitled for indemnification
and advancement of Expenses for providing consulting services to the
corporation. No amendment, alteration, rescission or replacement of this Exhibit
A or any provision hereof shall be effective as to the Consultant with respect
to any action taken or omitted by the Consultant in providing consulting
services to the corporation or with respect to any state of facts then or
previously existing or any Proceeding previously or thereafter brought or
threatened based in whole or to the extent based in part upon any such state of
facts existing prior to such amendment, alteration, rescission or replacement.

     Section l2. Insurance. The corporation may maintain, at its expense, an
insurance policy or policies to protect itself and the Consultant against
liability arising out of this Exhibit A or otherwise, whether or not the
corporation would have the power to indemnify any such person against such
liability under the Delaware General Corporation Law.

     Section l3. No Duplicative Payment. The corporation shall not be liable
under this Exhibit A to make any payment of amounts otherwise indemnifiable
hereunder if and to the extent that the Consultant has otherwise actually
received such payment under any insurance policy, contract, agreement or
otherwise.

     Section 14. Expenses of Adjudication. In the event that the Consultant
seeks a judicial adjudication, or an award in arbitration, to enforce the
Consultant's rights under, or to recover damages for breach of, this Exhibit A,
the Consultant shall be entitled to recover from the corporation, and shall be
indemnified by the corporation against, any and all expenses (of the types
described in the definition of Expenses in Section 1 actually and reasonably
incurred by the


                                       11
<PAGE>


Consultant in seeking such adjudication or arbitration, but only if the
Consultant prevails therein. If it shall be determined in such adjudication or
arbitration that the Consultant is entitled to receive part but not all of the
indemnification of expenses sought, the expenses incurred by the Consultant in
connection with such adjudication or arbitration shall be appropriately
prorated.

     Section 15. Severability. If any provision or provisions of this Exhibit A
shall be held to be invalid, illegal or unenforceable for any reason whatsoever:

     (a) the validity, legality and enforceability of the remaining provisions
of this Exhibit A (including without limitation, each portion of any Section of
this Exhibit A containing any such provision held to be invalid, illegal or
unenforceable, that is not itself invalid, illegal or unenforceable) shall not
in any way be affected or impaired thereby; and

     (b) to the fullest extent possible, the provisions of this Exhibit A
(including, without limitation, each portion of any Section of this Exhibit A
containing any such provision held to be invalid, illegal or unenforceable, that
is not itself held to be invalid, illegal or unenforceable) shall be construed
so as to give effect to the intent manifested by the provision held invalid.

such Questionnaire.

     (e) The  Purchaser  acknowledges  and is aware that the Company has minimal
assets and operating history and that the Notes are speculative investments.

     (f) The  Purchaser  acknowledges  and is aware that  there are  substantial

losing his entire  investment;  (iii) can bear the  economic  risk of losing his
entire  investment  herein;  and (iv)  does not have an  overall  commitment  to

twenty-one  (21) years of age; and if the Purchaser is a  corporation,  trust or

hereto  whether or not in violation of the  Securities  Act or other  applicable
Federal or state law, provided,  however,  that such party or parties who may be
seeking  indemnification  hereunder were acting within the  reasonable  scope of

     "The shares  represented by this certificate have not been registered under
     the  Securities  Act of 1933, as amended,  and may not be offered,  sold or

     registered under such Act or an opinion of counsel reasonably  satisfactory
     to the  Company is obtained  to the effect  that such  registration  is not
     required."

     The foregoing  legend shall be removed from the  certificates  representing
any Registrable  Shares,  at the request of the holder thereof,  at such time as
they become  eligible for resale  pursuant to Rule 144(k)  under the  Securities
Act.

C. Registration Rights

      1. Incidental Registration Rights. (a) If the Company at any time proposes
for any reason to register  any of its  securities  under the Act (other than in
connection  with its Initial  Public  Offering  or  pursuant  to a  registration
statement on Forms S-4, S-8 or similar or successor or another form which is not
available for  registering  Registrable  Securities for sale to the public),  it
shall each such time promptly give written  notice to all Holders of Registrable
Securities  of its  intention  so to do, and,  upon the written  request,  given
within 10 days after receipt of any such notice,  of such Holder to register any
Registrable  Securities,  which request shall specify the number of  Registrable
Securities  intended to be sold or  disposed of by such  Holders and shall state
the  intended  method of  disposition  of such  Registrable  Securities  by such
Holders,  the Company  shall use its best efforts to cause all such  Registrable
Securities  to be  registered  under the Act as  required  to permit the sale or
other  disposition  (in  accordance  with  the  intended  methods  thereof,   as
aforesaid) by such Holders.  Notwithstanding  the  foregoing,  the Company shall
have the right to  withdraw  such  registration  statement,  if so  required  by
prudent business judgment, provided it shall reimburse the persons who indicated
their intention to include Registrable  Securities therein for the out-of-pocket
expenses   reasonably   incurred  by  such  persons  in  connection   therewith.
"Registrable  Securities",  for  purposes of this  Section  6(c),  means (i) the
Shares  and (ii) any  shares of Common  Stock  issued as (or  issuable  upon the
conversion or exercise of any warrant,  right or other  security which is issued
as) a dividend or other  distribution with respect to, or in exchange for, or in
replacement of, any of such Shares.


<PAGE>


     (b) In the event that the proposed registration by the Company is, in whole
or in part, an underwritten  public offering of securities of the Company (other
than  the  Initial  Public  Offering  as to  which  the  Holder  shall  have  no
registration  rights  under this  Section  6(c)),  any request  pursuant to this
Section 6 to register  may specify  that the  Registrable  Securities  are to be
included in the  underwriting (i) on the same terms and conditions as the shares
of Common Stock, if any,  otherwise being sold through  underwriters  under such
registration  or (ii) on terms  and  conditions  comparable  to  those  normally
applicable to offerings of common stock in reasonably  similar  circumstances in
the event that no shares of Common Stock other than  Registrable  Securities are
being sold through underwriters under such registration; provided, however, that
if the managing underwriter determines and advises in writing that the inclusion
of all Registrable Securities proposed to be included in the underwritten public
offering and other issued and outstanding  shares of Common Stock proposed to be
included  therein by persons other than holders of Registrable  Securities  (the
"Other  Shares")  would   interfere  with  the  successful   marketing  of  such
securities,  then the number of Registrable Securities and Other Shares shall be
reduced pro rata among the holders of  Registrable  Securities and Other Shares,
as necessary.

     2. Demand  Registration.  At any time after the Company becomes eligible to
file a  Registration  Statement on Form S-3 (or any  successor  form relating to
secondary  offerings),  a Holder  holding in the  aggregate  at least 25% of the
Registrable  Shares  may  request  the  Company,   in  writing,  to  effect  the
registration  on Form S-3 (or such  successor  form).  Upon  receipt of any such
request,  the  Company  shall  promptly  give  written  notice of such  proposed
registration to all Holders. Such Holders shall have the right by giving written
notice to the Company within 30 days after the Company  provides its notice,  to
elect to have included in such registration such of their Registrable  Shares as
such  Holders  may request in such notice of  Election.  Thereupon,  the Company
shall,  as  expeditiously  as  possible,  use its best  efforts  to  effect  the
registration  on Form S-3, or such  successor  form, of all  Registrable  Shares
which the Company has been requested to register.

     3. Preparation  and  Filing.  If and  whenever  the  Company  is  under an
obligation  pursuant  to the  provisions  of this  Section  6(c) to use its best
efforts to effect the  registration of any Registrable  Securities,  the Company
shall, as expeditiously as practicable:

     (a) prepare and file with the SEC a registration  statement with respect to
such securities and use its best efforts to cause such registration statement to
become and remain effective;

     (b) prepare and file with the SEC such  amendments and  supplements to such
registration  statements and the prospectus used in connection  therewith as may
be necessary to keep such  registration  statement  effective  for at least nine
months and to comply with the  provisions of the  Securities Act with respect to
the sale or other  disposition  of all  Registrable  Securities  covered by such
registration statement;

      (c) furnish to each  seller such number of copies of a summary  prospectus
or other prospectus,  including a preliminary prospectus, in conformity with the
requirements  of the Securities Act, and such other documents as such seller may
reasonably  request in order to facilitate the public sale or other  disposition
of such Registrable Securities;

      (d) use its best efforts to register or qualify the Registrable Securities
covered by such registration  statement under the securities or blue sky laws of
such jurisdictions as each


<PAGE>


such seller shall reasonably request (provided,  however, that the Company shall
not be  required to consent to general  service of process  for all  purposes or
qualify to do business in any  jurisdiction  where it is not then qualified) and
do any and all  other  acts or  things  which  may be  reasonably  necessary  or
advisable  to  enable  such  seller  to  consummate  the  public  sale or  other
disposition in such jurisdictions of such securities; and

     (e)  notify  each  seller  of  Registerable   Securities  covered  by  such
registration statement at any time when a prospectus relating thereto covered by
such registration statement is required to be delivered under the Securities Act
within the  appropriate  period  mentioned in clause (b) of this ss.8.3,  of the
happening  of any  event as a result of which the  prospectus  included  in such
registration  statement,  as then in effect,  includes an untrue  statement of a
material fact or omits to state a material fact required to be stated therein or
necessary  to make the  statements  therein not  misleading  in the light of the
circumstances  then  existing,  and at the request of such  seller,  prepare and
furnish to such seller a reasonable  number of copies of a  supplement  to or an
amendment  of  such  prospectus  as may be  necessary  so  that,  as  thereafter
delivered  to the  purchasers  of such  securities,  such  prospectus  shall not
include an untrue  statement of a material fact or omit to state a material fact
required to be stated  therein or necessary to make the  statements  therein not
misleading in the light of the circumstances then existing.

     4. Registration  Expenses.  All Registration Expenses incurred in complying
with this Section 6(c) shall be paid for by the Company.

     5.  Indemnification.  In the  event  of  any  registration  of  Registrable
Securities  under the  Securities  Act  pursuant to this  Section  6(c) or other
registration or qualification thereof pursuant to Section 6(c)(3)(d) hereof, the
Company shall enter into an indemnity  agreement with the sellers of Registrable
Securities in customary form relating thereto.

     6.  Assignment.  The rights to cause the  Company to  register  Registrable
Securities  pursuant  to this  Section  6 may be  assigned  by a  Holder  to any
transferee or assignee of Registrable Securities upon the transfer or assignment
of all Registrable  Securities held by such Holder or a minimum of 20% of shares
of such Registrable Securities; provided that the Company is notified in writing
of such transfer,  the proposed transferee or assignee agrees to be bound by the
provisions of this Subscription Agreement.

7. ENTIRE AGREEMENT

     This Agreement contains the entire understanding between the parties hereto
and supersedes any prior  understanding  and agreements  between them respecting
the subject matter of this Agreement.

8. GOVERNING LAW

      This  Agreement  shall be  governed,  construed,  and  interpreted  in all
respects,  in  accordance  with the  internal  laws of the  State of  California
applicable to contracts made and to be performed  wholly therein,  except to the
extent  that by its terms the General  Corporation  Law of the State of Delaware
