- - Dental Care Alliance, Inc., a Delaware corporation.
    
 
   
The Mergers--
    
 
   
- - The Boards of Directors of Gentle Dental and Dental Care Alliance have agreed
  on a combination that will create one of the largest dental practice
  management companies in the nation.
    
 
   
- - Gentle Dental and Dental Care Alliance will each become a wholly-owned
  subsidiary of a new Delaware company named "Wisdom Holdings, Inc."
    
 
   
- - Gentle Dental shareholders will receive one share of the new company's common
  stock for each share of Gentle Dental common stock they own immediately prior
  to the mergers and one share of preferred stock with the same designations for
  each share of Gentle Dental preferred stock they own.
    
 
   
- - Dental Care Alliance stockholders will receive 1.67 shares of the new
  company's common stock for each share of Dental Care Alliance common stock
  they own immediately prior to the mergers.
    
 
   
- - The new company will have affiliated dental practices in California, Florida,
  Georgia, Hawaii, Idaho, Michigan, Oregon, Pennsylvania and Washington.
    
 
   
We cannot complete the combination unless the stockholders of both of our
companies approve it. Gentle Dental and Dental Care Alliance will each hold a
meeting of its stockholders to vote on the Agreement and Plan of Reorganization
and Merger. Your vote is very important. Whether or not you plan to attend your
stockholder meeting, please take the time to vote by completing and mailing the
enclosed proxy card to us. If you sign, date and mail your proxy card without
indicating how you want to vote, your proxy will be counted as a vote in favor
of the merger agreement. Not returning your card or not instructing your broker
how to vote any shares held for you in "street name" will have the same effect
as a vote against the merger agreement.

THE MERGERS (PAGE 26)
    
 
   
WE HAVE ATTACHED THE MERGER AGREEMENT TO THIS DOCUMENT AS APPENDIX A WHICH
AGREEMENT IS INCORPORATED HEREIN BY THIS REFERENCE AND WHICH DESCRIBES THE
COMBINATION BETWEEN OUR COMPANIES. PLEASE READ THE MERGER AGREEMENT. IT IS THE
LEGAL DOCUMENT THAT GOVERNS THE MERGERS.
    
 
   
GENERAL
    
 
   
We propose a combination in which Gentle Dental and Dental Care Alliance will
each merge with a separate wholly-owned subsidiary of Wisdom Holdings, Inc., a
newly-formed Delaware corporation. As a result of these mergers, each of our
companies will become wholly-owned subsidiaries of Wisdom Holdings, Inc. We hope
to complete the mergers by February 28, 1999.
    
 
   
OUR REASONS FOR THE MERGERS (PAGES 29 AND 30)
    
 
   
Our companies are proposing to combine because we believe for example, that
    
 
   
- - together we can create a larger and more stable company that will provide
  significant benefits to our stockholders
    
 
   
- - the larger size of the new company should help us to reduce duplicate costs
    
 
                                       1
<PAGE>
   
- - the new company can do a better job of increasing our revenues than we could
  if we did not merge
    
 
   
- - the combination between Gentle Dental and Dental Care Alliance will strengthen
  our position as a competitor in the dental practice management industry, which
  is evolving, consolidating and growing more competitive.
    
 
   
In reaching these beliefs and arriving at our decisions to recommend the mergers
to our stockholders, we considered a number of factors. For example, we
considered
    
 
   
- - our familiarity with our businesses, operations, financial conditions,
  earnings and prospects
    
 
   
- - our ability to successfully combine and integrate our operations
    
 
   
- - our perception of the value of the consideration in the mergers to our
  stockholders
    
 
   
- - our due diligence investigations of the other's businesses
    
 
   
- - the advice of our financial and legal advisors and of our independent
  auditors.
    
 
   
EXCHANGE OF SHARES (PAGE 44)
    
 
   
GENTLE DENTAL SHAREHOLDERS.  Following the mergers, each of your shares of
Gentle Dental common stock will automatically become exchangeable for one share
of the new company's common stock and each share of Gentle Dental preferred
stock will automatically become exchangeable for one share of the new company's
preferred stock, with the same rights, preferences and privileges as to the new
company as each share of preferred stock had as to Gentle Dental. For example,
if you owned ten shares of Gentle Dental common stock, after the mergers you
will exchange your old Gentle Dental certificates for ten shares of the new
company's common stock.
    
 
   
For more information on how this exchange procedure works, see "Exchange of
Certificates; Fractional Shares" on page 46 of this document.
    
 
   
DENTAL CARE ALLIANCE STOCKHOLDERS.  Following the mergers, each of your shares
of Dental Care Alliance common stock will automatically become exchangeable for
1.67 shares of the new company's common stock. The total number of shares you
receive will therefore be equal to 1.67 times the number of shares of Dental
Care Alliance common stock you own. The new company will not issue fractional
shares. Instead, you will receive the value of any fractional share in cash,
based on the market value of Gentle Dental's common stock. For example, if you
owned ten shares of Dental Care Alliance common stock, after the mergers you
will exchange your old Dental Care Alliance certificates for 16 shares of the
new company's common stock and a check for seven-tenths multiplied by the
average of the closing sale prices of Gentle Dental common stock for the five
consecutive trading days prior to the Gentle Dental merger.
    
 
   
For more information on how this exchange procedure works, see "Exchange of
Certificates; Fractional Shares" on page 46 of this document.
    
 
   
Prior to completion of the mergers, there has been no public market for the new
company's common stock. As a result, the value of the consideration received by
the stockholders of Gentle Dental and Dental Care Alliance is based upon the
trading value of Gentle Dental's common stock. See "Price Range of Common Stock
and Dividends" at page 11.
    
 
   
Based on the exchange ratio in the merger for Dental Care Alliance shares, which
is 1.67, the market value of the consideration that Dental Care Alliance
stockholders will receive in the merger for each share of Dental Care Alliance
common stock would be $9.50, based on the average of the closing bid and ask
prices for Gentle Dental's common stock on October 15, 1998 and           based
on the average of the closing bid and ask prices for Gentle Dental's common
stock on           , 1998. Of course, the market price of Gentle Dental and
Dental Care Alliance common stock will fluctuate prior to the mergers, while the
exchange ratio is fixed.
    
 
   
You should obtain current stock price quotations for Gentle Dental common stock
and Dental Care Alliance common stock. These quotations are available from your
stockbroker, in major newspapers such as THE WALL STREET JOURNAL and on the

recommends that you vote "FOR" the proposal to approve the merger agreement.
    
 
   
DENTAL CARE ALLIANCE STOCKHOLDERS.  The Board of Directors of Dental Care
Alliance believes that the merger agreement is fair to you and in your best

RECORD DATE AND VOTING RIGHTS (PAGE 24)
    
   
GENTLE DENTAL SHAREHOLDERS.  You can vote on the merger agreement at the meeting
of Gentle Dental shareholders if you owned Gentle Dental common stock or Gentle
Dental preferred stock at the close of business on December 7, 1998. You can
cast one vote regarding the Agreement and Plan of Reorganization and Merger for
each share of Gentle Dental common stock and one vote for each share of Gentle
Dental preferred stock that you owned at that time.
    
 
   
DENTAL CARE ALLIANCE STOCKHOLDERS.  You can vote on the Agreement and Plan of
Reorganization and Merger at the meeting of Dental Care Alliance stockholders if
you owned Dental Care Alliance common stock at the close of business on December
8, 1998. You can cast one vote for each share of Dental Care Alliance common
stock that you owned at that time.
    
 
   
APPRAISAL RIGHTS (PAGE 116)
    
 
   
GENTLE DENTAL SHAREHOLDERS.  Washington law permits you to dissent from the
merger and have the fair value of your stock appraised by a court and paid to
you in cash. In order to do this, you must follow certain procedures, including
filing certain notices. Also, you must not vote your shares in favor of the
mergers if you wish to receive a cash payment for your shares.
    
 
   
You will not receive any stock in the new company if you dissent and follow all
of the required procedures. Instead, you will only receive the value of your
stock in cash. The value of your stock will be the fair value of your stock
immediately prior to the mergers, without giving effect to the anticipated
combination. The relevant sections of Washington law governing this process are
attached to this document as Appendix E.
    
 
   
DENTAL CARE ALLIANCE STOCKHOLDERS. Delaware law does not provide you with
dissenters' appraisal rights in the mergers.

agreement. As of             , 1998, the Gentle Dental officers, directors and
significant shareholders who have executed the Stockholders' Agreement represent
approximately     % of the total voting power of Gentle Dental common stock and
approximately    %,    % and     % of the total voting power of Gentle Dental
Series A, Series C and Series D preferred stock.
    
 
   
As of             , 1998, the Dental Care Alliance officers and directors who
have executed a Stockholders' Agreement represent approximately     % of the
total voting power of Dental Care Alliance common stock. We have attached a copy
of the form of the Stockholders' Agreement to this document as Appendix D.
    
 
   
INTERESTS OF DIRECTORS AND OFFICERS IN THE MERGERS THAT ARE DIFFERENT FROM YOUR
INTERESTS (PAGE 57)
    
 
   
Some of our directors and officers have interests in the mergers that are
different from, or in addition to, their interests as stockholders in our
companies. These interests exist because of agreements with Gentle Dental or
Dental Care Alliance, including provisions in employment agreements and rights
that certain officers have under retention, incentive or benefit and
compensation plans maintained by Gentle Dental or Dental Care Alliance.
    
 
   
Wisdom Holdings, Inc. has agreed to assume responsibility for these agreements
and plans. Some of these agreements and plans will provide the officers with
severance benefits if their employment with Wisdom Holdings, Inc. is terminated
after the merger. See "The Mergers--Interests of Certain Persons in the Mergers"
at page    of this document. The members of our boards knew about these
additional interests, and considered them, when they approved the merger
agreement.
    
 
   
MANAGEMENT AND OPERATIONS AFTER THE MERGERS (PAGE 61)
    
 
   
The present management teams of our companies will share the responsibility of
managing Wisdom Holdings, Inc. The Board of Directors of Wisdom Holdings, Inc.
will initially be composed of eight directors. Five will come from Gentle Dental
and three will come from Dental Care Alliance. The Gentle Dental directors will
include:
    
 
   
- - Michael T. Fiore, Co-Chairman, President and Chief Executive Officer of Gentle
  Dental;
    
 
   
- - Robert Finzi;
    
 
   
- - Eric Green;
    
 
   
- - Wayne Posey; and
    
 
   
- - Paul H. Keckley.
    
 
   
The Dental Care Alliance directors will include:
    
 
   
- - Dr. Steven R. Matzkin, Chairman, President and Chief Executive Officer of
  Dental Care Alliance;
    
 
   
- - Robert F. Raucci; and
    
 
   
- - Curtis Lee Smith, Jr.
    
 
   
Mr. Fiore will be Co-Chairman of the Board of Directors and Chief Executive
Officer. Dr. Matzkin will be Co-Chairman of the Board of Directors and President
and Chief Dental Officer.
    
 
   
While no assurances can be made, we expect to achieve cost savings and
additional revenue opportunities that should have a beneficial effect on our
earnings per share. We also expect to recognize charges to earnings related to
expenses and costs of integrating our two companies in both 1998 and 1999.
    
 
   
CERTAIN DIFFERENCES IN THE RIGHTS OF STOCKHOLDERS (PAGE 107)
    
 
   
The rights of Gentle Dental shareholders are currently governed by the
Washington Business Corporation Act, the Amended and Restated Articles of
Incorporation of Gentle Dental and the Gentle Dental By-laws. The rights of
Dental Care Alliance stockholders are currently governed by the Delaware General
Corporation Law, the Dental
    
 
                                       4
<PAGE>
   
Care Alliance Restated Certificate of Incorporation and the Dental Care Alliance
By-laws. Upon our completion of the mergers, you will become stockholders of the
new company, and your rights will be governed by the Delaware General
Corporation Law and by the new company's certificate of incorporation and
by-laws.
    
 
   
WHAT WE NEED TO DO TO COMPLETE THE MERGERS (PAGE 51)
    
 
   
The completion of the mergers depends on a number of conditions being met.
    
 
   
Where law permits, Gentle Dental or Dental Care Alliance could decide to
complete the mergers even though one or more of these conditions have not been
met. We cannot be certain when (or if) the conditions to the mergers will be
satisfied or waived, or that the mergers will be completed.
    
 
   
TERMINATION OF THE MERGER AGREEMENT; EXPENSES (PAGE 55)
    
 
   
We can agree at any time to terminate the merger agreement without completing
the mergers, even if the stockholders of both companies have approved it. Also,
either of us can decide, without the consent of the other, to terminate the
merger agreement under certain circumstances.
    
 
   
In the event the mergers are not completed, each party will pay its own
expenses, except that we will evenly divide registration fees that we will have
to pay to the Securities and Exchange Commission. Also, in the event the mergers
are not completed because the merger agreement is terminated under its terms for
a breach, the breaching party will be liable to the non-breaching party for an
amount up to the actual out-of-pocket costs and expenses of the non-breaching
party. However, in the event that:
    
 
   
- - either of our boards of directors fails to recommend the mergers or withdraws
  or modifies a recommendation in a manner adverse to the other party, other
  than a failure to recommend following a termination permitted by the
  agreement; or
    
 
   
- - either of our companies accepts an acquisition proposal from a third party
    
 
   
the party that fails to recommend, withdraws or modifies a recommendation or the
party that accepts a third party acquisition proposal will pay the other party a
termination fee equal to $1.5 million.
    
 
   
WAIVER AND AMENDMENT (PAGE 56)
    
 
   
We can agree to amend the merger agreement and each of us can waive our right to
require the other party to adhere to the terms and conditions of the merger
agreement, where the law allows. However, we may not do so after our
stockholders approve the mergers, if the amendment or waiver reduces the
consideration that will be received by Gentle Dental shareholders or Dental Care
Alliance stockholders, unless the affected stockholders approve the amendment or
waiver.
    
 
   
ACCOUNTING TREATMENT (PAGE 55)
    
 
   
We expect the combination of our companies through the mergers to qualify as a
"pooling of interests." This means that, for accounting and financial reporting
purposes, we will treat our companies as if they had always been one company.
    
 
   
While the parties expect to account for the mergers as a pooling-of-interests,
the Securities and Exchange Commission could take a different view and require
the new company to use purchase accounting.
    
 
   
REGULATORY APPROVALS (PAGE 53)
    
 
   
Notification of the combination is being given to the U.S. Department of Justice
and the Federal Trade Commission. The mergers cannot be completed until a
waiting period has expired or is earlier terminated without objection to the
mergers by these governmental entities.
    
 
   
In addition, certain state and other regulatory authorities will need to approve
or be notified of the mergers before we can complete them.
    
 
   
We have filed, or soon will file, all of the required applications or notices
with these regulatory agencies.
    
 
                                       5
<PAGE>
   
As of the date of this document, we have not yet received the required
approvals. While we do not know of any reason why we would not be able to obtain
the necessary approvals in a timely manner, we cannot be certain when or if we
will get them.
    
 
   
CERTAIN FEDERAL INCOME TAX CONSEQUENCES (PAGE 53)
    
 
   
GENTLE DENTAL SHAREHOLDERS.  We expect that your exchange or conversion of
shares of Gentle Dental common or Series D preferred stock for shares of common
or Series D preferred stock of the new company generally will not cause you to
recognize any gain or loss for purposes of United States federal income tax.
    
   
DENTAL CARE STOCKHOLDERS.  We expect that your exchange of shares of Dental Care
Alliance common stock for shares of common stock of the new company generally
will not cause you to recognize any gain or loss for purposes of United States
federal income tax. You will, however, have to recognize gain in connection with
any cash received instead of fractional shares.
    
 
   
While we will receive legal opinions about the federal income tax treatment of
our stockholders, these opinions will not bind the Internal Revenue Service,
which could take a different view.
    
 
   
THIS TAX TREATMENT MAY NOT APPLY TO CERTAIN GENTLE DENTAL SHAREHOLDERS AND
CERTAIN DENTAL CARE ALLIANCE STOCKHOLDERS, INCLUDING THE GENTLE DENTAL
SHAREHOLDERS WHO DISSENT FROM THE MERGERS. DETERMINING THE ACTUAL TAX
CONSEQUENCES OF THE MERGERS TO YOU CAN BE COMPLICATED. THEY WILL DEPEND ON YOUR
SPECIFIC SITUATION AND ON VARIABLES NOT WITHIN OUR CONTROL. YOU MAY WISH TO
CONSULT YOUR OWN TAX ADVISOR FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES OF
THE MERGERS.
    
 
   
RISK FACTORS (PAGE 12)
    
 
   
In deciding whether to vote for the approval of the merger agreement, you should
carefully evaluate the information provided in the section entitled "Risk
Factors" in addition to the other information described in this document.

                 SELECTED UNAUDITED COMPARATIVE PER SHARE DATA
 
   
The following table shows information about our income per share and book value
per share, and similar information reflecting the mergers (which we refer to as
"pro forma" information). In presenting the comparative pro forma information
for certain time periods, we assumed that we had been merged throughout these
periods. The information below does not include the pro forma impact of other
acquisitions which are included in the pro forma financial information beginning
on page 8.
    
 
We also assumed that we will treat our companies as if they had always been
combined for accounting and financial reporting purposes (a method known as
"pooling of interests" accounting). We expect that we will incur reorganization
and restructuring expenses as a result of combining our companies. We also
anticipate that the mergers will provide the new company with financial benefits
that include reduced operating expenses and the opportunity to earn more
revenue. The pro forma information, while helpful in illustrating the financial
characteristics of the new company under one set of assumptions, does not
attempt to predict or suggest future results.
   
The information in the following table is based on the historical financial
information which is included elsewhere in this document or incorporated by
reference to information that we have presented in our prior Securities and
Exchange Commission filings.

                   SUMMARY PRO FORMA COMBINED FINANCIAL DATA
                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
    
 
   
    The following pro forma financial data presents the combined results of
Gentle Dental and Dental Care Alliance, which are expected to combine in a
transaction expected to be accounted for as a pooling of interests. The pro
forma financial data has been derived from the consolidated financial statements
of the companies and should be read in conjunction with such statements, the
notes related thereto and each of the companies' "Management's Discussion and
Analysis of Financial Condition and Results of Operations" appearing elsewhere
herein.
    
 
   
    The following summary pro forma combined financial data presented below are
unaudited and were prepared by management of the companies on the same basis as
the audited financial statements included elsewhere herein and, in the opinion
of management of the companies, include all adjustments necessary to present
fairly the information set forth herein and give effect to the mergers between
Gentle Dental Service Corporation and Dental Care Alliance, Inc. as if they had
occurred on September 30, 1998 using the pooling-of-interests method of
accounting. The pro forma financial data for the years ended December 31, 1997
and the nine months ended September 30, 1998 include the results of all
practices acquired (from an accounting point of view) as if the acquisitions had
occurred on January 1, 1997. Additionally, such results reflect the impact of
Gentle Dental's private placement that occurred in May and June of 1998 as if
the private placement occurred on January 1, 1997 and the effect of the amended
management agreements with certain professional corporations. The summary pro
forma combined financial and operating data is not necessarily indicative of the
actual results of operations or financial position that would have been achieved
had such transactions been completed at the dates specified above, nor are the
statements necessarily indicative of the new company's future results of
operations or financial position.

                                  RISK FACTORS
 
    IN ADDITION TO THE INFORMATION CONTAINED ELSEWHERE IN THIS JOINT PROXY
STATEMENT-PROSPECTUS OR INCORPORATED HEREIN BY REFERENCE, GENTLE DENTAL
SHAREHOLDERS AND DENTAL CARE ALLIANCE STOCKHOLDERS CONSIDERING THIS PROPOSAL TO
APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION AND MERGER SHOULD CAREFULLY
CONSIDER THE FOLLOWING FACTORS, AMONG OTHERS, BEFORE MAKING ANY FINAL DECISION.
 
FORWARD-LOOKING STATEMENTS MAY NOT PROVE ACCURATE
 
   
    When used or incorporated by reference in this document, the words
"anticipate," "estimate," "expect," "project," "believe" and similar words or
expressions are intended to identify forward-looking statements. Such statements
are subject to certain risks, uncertainties and assumptions, including those set
forth below. Should one or more of these risks or uncertainties materialize, or
should underlying assumptions prove incorrect, actual results may vary
materially from those anticipated, estimated, expected or projected. Several key
factors that have a direct bearing on our ability to attain our goals are
discussed below.
    
 
   
WE MAY NOT BE ABLE TO SUCCESSFULLY INTEGRATE OUR OPERATIONS
    
 
   
    Because of inherent uncertainties associated with integrating combining
companies, there can be no assurance that the new company will be able to
realize fully the operating efficiencies Gentle Dental and Dental Care Alliance
currently expect to realize as a result of the combination. Each of Gentle
Dental and Dental Care Alliance conducts business and maintains separate
administrative operations in different regions of the United States and there
can be no assurance that we will be able to successfully integrate such
operations or that such operating efficiencies or successful integration will be
realized in the time frame currently anticipated.
    
 
   
WE MAY NOT BE ABLE TO SUCCESSFULLY MANAGE AND MAINTAIN OUR GROWTH
    
 
   
    Gentle Dental and Dental Care Alliance each are experiencing growth in
existing and new markets through affiliations with additional dental practices
and through expanding operations of existing affiliated dental practices. Our
ability to manage and maintain our growth will depend on many factors, including
our ability to successfully:
    
 
   
    - identify, attract and retain desirable affiliation targets;
    
 
   
    - negotiate favorable affiliation terms;
    
 
   
    - obtain acceptable financing to fund our growth;
    
 
   
    - complete affiliations in a timely manner;
    
 
   
    - integrate newly affiliated dental practices;
    
 
   
    - hire and train personnel to accommodate expanded operations;
    
 
   
    - establish, maintain and expand new and existing payor and customer
      relationships; and
    
 
   
    - manage initial periods of negative or limited contributions to our
      operating results that often occur when we enter new markets.
    
 
   
    There can be no assurance that we will be able to accomplish these
objectives. Failure to meet one or more of these objectives could have a
material adverse effect on our business, financial condition and results of
operations.
    
 
   
WE DEPEND UPON THE OPERATIONS OF OUR AFFILIATED DENTAL PRACTICES
    
 
   
    We receive fees for services provided to affiliated dental practices under
management agreements and, except as permitted by applicable law we do not
generally directly employ dentists or control the
    
 
                                       12
<PAGE>
   
professional dental aspects of the practices which require a license to practice
dentistry. Our profitability is dependent on the revenue and expenses of the
affiliated dental practices. Any material loss of revenue or increase in the
expenses of the affiliated dental practices could have a material adverse effect
on the new company.
    
 
   
    From time to time, we enter into or amend management agreements and the
affiliated dental practices enter into or amend employment agreements with
dentists, which may have a material impact on the revenue and expenses of the
affiliated dental practices. Gentle Dental's management agreements with the
affiliated dental practices generally have terms of 40 years and Dental Care
Alliance's management agreements generally have terms of 25 years. However,
certain of Dental Care Alliance's management agreements, which account for
approximately 2.3% of the new company's pro forma revenues for the year ended
December 31, 1997, and 3.7% of its pro forma revenues for the nine months ended
September 30, 1998, terminate between 1998 and 2005. Any breach, expiration or
termination of management agreements could have a material adverse effect on the
new company.
    
 
   
WE MAY NOT BE ABLE TO OBTAIN ACCEPTABLE FINANCING
    
 
   
    Our expansion strategy will require substantial funding. Moreover, the
operation of our combined network of affiliated dental practices will require
ongoing working capital and capital expenditures for renovation, expansion and
the addition of dental equipment and technology used to provide dental services.
We expect that capital requirements over the next several years will
substantially exceed cash flow generated from operations and borrowings
available under current credit facilities of Gentle Dental and Dental Care
Alliance. There can be no assurance that we will be able to obtain additional
required capital on satisfactory terms, if at all. The failure to raise the
funds necessary to finance future cash requirements could materially adversely
affect our ability to pursue our expansion strategy and the new company's
business, financial condition and results of operations for future periods. If
additional funds are raised through the issuance of equity securities, dilution
to stockholders may result. If additional funds are raised through the
incurrence of debt, such debt instruments will likely contain restrictive
financial, maintenance and security covenants.
    
 
   
WE MAY NOT BE ABLE TO ATTRACT AND RETAIN PROFESSIONALS, MANAGEMENT OR STAFF
    
 
    A key component of our operating strategy will be to increase profitability
by maximizing patient's use of our affiliated dental practices through extended
hours of operation and the addition of general dentists, specialists, hygienists
and dental assistants. Accordingly, our financial success will be dependent, in
part, upon our ability to attract and retain a sufficient number of qualified
dentists, specialists, hygienists and dental assistants. No assurance can be
given that we will be able to attract qualified dentists, specialists and
clinical staff at acceptable compensation levels, or at all. Failure to
appropriately staff affiliated dental practices could have an adverse effect on
the new company's business, financial condition and results of operations. We
believe that our future success also will depend in part upon our ability to
attract and retain qualified management personnel. Competition for such
personnel is intense and we will compete with numerous other employers, some of
which may have greater financial and other resources. There can be no assurance
that we will be successful in attracting and retaining such personnel.
 
   
COMPETITION
    
 
   
    We compete with other dental practice management companies seeking to
affiliate with dental practices in the highly competitive dental practice
management industry. We are aware of a number of competitors specializing in the
business of providing comprehensive management services to dental practices and
there are other companies with substantial resources that may decide to enter
the industry. There can be no assurance that we will be able to successfully
identify, attract and retain dental practices and an inability to do so, would
have a material adverse effect on the new company's business, financial
condition and results of operations.
    
 
                                       13
<PAGE>
   
    Additionally, the market for general and specialty dental services is highly
fragmented and is characterized by large numbers of individual practitioners and
small group practices competing for individual patients. Competition for the
provision of dental services is highly competitive in the markets in which our
combined network of affiliated dental practices operate and often includes
practitioners who have established practices and reputations. There can be no
assurance that our combined network of affiliated dental practices will be able
to compete effectively in the markets they serve, and an inability to do so
would have a material adverse effect on the new company's business, financial
condition and results of operations.
    
 
   
WE DEPEND UPON THIRD PARTY PAYORS
    
 
   
    A significant portion of the payment for services rendered by our affiliated
dental practices is paid by private insurance programs. There is, and has been
in recent years, an ongoing effort by third-party and government payors to
contain and reduce health care and dental care costs, and impose lower
reimbursement rates on health care providers. Such initiatives may result in a
reduction in per-patient and per-procedure revenue from historic levels. In the
event that third-party payors are successful in obtaining lower rates for
specified services, the new company's business, financial condition and results
of operations may be materially adversely affected. Additionally, contracts
between third-party and governmental payors and our affiliated dental practices
typically are short-term arrangements, having terms of one year or less.
Substantially all of these agreements also allow the third-party or governmental
payor to cancel the agreement prior to expiration of its term. Cancellation or
failure to renew or extend one or more material payor agreements could
materially and adversely affect the new company's business, financial condition
and results of operations.
    
 
   
WE ARE SUBJECT TO RISKS OF MANAGED CARE AND CAPITATED MANAGED DENTAL CARE
  CONTRACTS
    
 
   
    Managed care arrangements typically shift some of the economic risk of
providing patient care from the person who pays for the care to the provider of
the care by capping fees, requiring reduced fees, or paying a set fee per
patient irrespective of the amount of care delivered. There can be no assurance
that managed care arrangements will not become more prevalent in the dental care
field in the future, that the downward pressures on fees associated with managed
care will not increase, or that we will not be adversely affected by growth in
managed dental care.
    
 
   
    Under capitated managed dental care contracts, the dentist is typically paid
a predetermined monthly capitation payment amount per patient from the payor in
exchange for providing all necessary covered services to the patients covered
under the arrangement. This arrangement shifts the risks of utilization of such
services to our affiliated dental practices that provide the dental services.
These types of contracts pass most of the financial risk of providing dental
care, including the risk of over-utilization, from the payor to the dentist. Our
success, in part, will be dependent upon our ability to negotiate contracts on
behalf of the affiliated dental practices with health maintenance organizations,
employer groups and other third-party payors, pursuant to which services will be
provided on a risk-sharing or capitated basis by some or all of the affiliated
dental practices. There can be no assurance that the affiliated dental practices
will be able to negotiate satisfactory arrangements on a capitated or other
risk-sharing basis. In addition, to the extent that patients or enrollees
covered by such arrangements require more frequent or extensive care than is
anticipated, we would incur unanticipated costs not offset by additional
revenue. This would reduce operating margins. Health care reforms being
considered at the federal and state levels could result in a mandate that
managed care patients receive certain benefits. No assurance can be given that
the affiliated dental practices will be successful in negotiating adjustments to
capitation rates that will adequately compensate the affiliated dental practices
for performing such procedures. Any such reduction or elimination of earnings
could have a material adverse effect on the new company's business, financial
condition and results of operations.
    
 
                                       14
<PAGE>
   
WE DEPEND UPON CERTAIN KEY PERSONNEL
    
 
   
    The success of the new company will be dependent upon the continued services
of certain of its senior management team, including the Co-Chairman of the Board
and Chief Executive Officer, Michael T. Fiore, and the Co-Chairman of the Board,
President and Chief Dental Officer, Dr. Steven R. Matzkin. The loss of services
of one or both of these individuals could have a material adverse effect on the
new company's business, financial condition and results of operations. There can
be no assurance that these individuals will remain with the new company or that
it will be able to attract and retain other key management personnel.
    
 
   
WE ARE SUBJECT TO DEFAULT RISKS ASSOCIATED WITH NOTES FROM AND ADVANCES TO
  AFFILIATED PROFESSIONAL ASSOCIATIONS
    
 
   
    Dental Care Alliance has made, and the new company intends to continue to
make, loans to affiliated dental practices to finance the purchase of the dental
assets of affiliated dental practices. These loans are evidenced by notes that
are secured by the dental assets of such affiliated dental practices. They are
personally guaranteed by the dentists who own such affiliated dental practices.
The loans are recorded on Dental Care Alliance's balance sheet as "Notes
Receivable from PAs" until repaid. At December 31, 1997 and September 30, 1998,
Notes Receivable from PAs were $397,462 and $762,430, respectively. "Management
fee receivable from PAs" consist of amounts owed to Dental Care Alliance related
to revenue recorded in accordance with management agreements and is recorded
based upon the net realizable value of patient accounts receivable of the
principal associations. The failure of any of the affiliated dental practices to
repay such notes or advances could have a material adverse effect on the new
company's business, results of operations and financial condition.
    
 
   
    Management believes that the total dollar amount outstanding under these
loans will increase in the future as the new company expands its network of
dental practices under management. In addition, the company may advance funds to
affiliated dental practices to cover their expenses in the event that the
revenue retained by any affiliated dental practice after paying management fees
to the new company is not sufficient to pay its expenses. This is often the case
with newly integrated dental practices and occurs from time to time with other
affiliated dental practices. Such advances are recorded on Dental Care
Alliance's balance sheet as "Advances to PAs" until repaid. At December 31, 1997
and September 30, 1998, Advances to PAs were $483,421 and $3,015,900,
respectively. Any decision by the new company to continue to make loans,
receivables or advances to affiliated dental practices or the sustained
inability of affiliated dental practices to pay their expenses could necessitate
adjustments to the management agreements with such affiliated dental practices
or could cause the new company to record additional reserves with respect to
such loans or advances. Either of these events could have a material adverse
effect on the new company's business, results of operations and financial
condition. To date there have been no such downward adjustments to any of the
management agreements, nor do the management agreements provide for any form of
retroactive downward adjustment. The risks disclosed in the risk factor
captioned "Government Regulation" apply to the notes and advances described in
this risk factor.
    
 
   
WE ARE SUBJECT TO AN ADVERSE EARNINGS IMPACT ASSOCIATED WITH MANAGEMENT
  AGREEMENTS AND OTHER INTANGIBLE ASSETS
    
 
   
    A substantial portion of the new company's assets will consist of management
agreements and other intangible assets. At September 30, 1998, on a pro forma
basis, the new company would have had approximately $148.1 million of total
assets (of which approximately $94.4 million were intangible assets) and
approximately $70.3 million in total stockholders' equity. We expect the amount
of intangible assets to increase further in the future in connection with
additional dental practice affiliations. This increase will have an adverse
impact on earnings as the intangible assets are amortized. In the event of any
sale or liquidation of the new company or a portion of its assets, there can be
no assurance that the recorded value of the management agreements will be
realized. When factors indicate that the amount allocable to one or
    
 
                                       15
<PAGE>
   
more of the management agreements or other intangible assets should be evaluated
for possible impairment, we may be required to reduce the carrying value of such
management agreements or other intangible assets, which could have a material
adverse effect on the results of operations of the new company during the
periods in which such reductions are recognized.
    
 
   
GOVERNMENT REGULATION
    
 
   
    The dental industry is regulated extensively at both the state and federal
levels. Regulatory oversight includes, but is not limited to, considerations of
fee-splitting, corporate practice of dentistry, anti-kickback and anti-referral
legislation and state insurance regulation. Although we believe that the
operations of Gentle Dental and Dental Care Alliance comply in all material
respects with the laws to which they are subject, there can be no assurance that
a review of our business relationships by courts or other regulatory authorities
would not result in determinations that could prohibit or otherwise adversely
affect operations or that the regulatory environment will not change, requiring
us to reorganize, change our methods of reporting revenues and other financial
results or restrict existing or future operations. Any such change could have a
material adverse effect on the new company's business, financial condition and
results of operations.
    
 
    CORPORATE PRACTICE OF DENTISTRY; FEE SPLITTING.  The laws of many states
prohibit dentists from splitting fees with non-dentists and prohibit non-dental
entities from engaging in the practice of dentistry or employing dentists to
practice dentistry. The specific restrictions against the corporate practice of
dentistry as well as the interpretations of those restrictions by state
regulatory authorities vary from state to state. The restrictions are generally
designed to prohibit a non-dental entity from controlling the professional
practice of a dentist, employing dentists to practice dentistry (or, in certain
states, employing dental hygienists or dental assistants), controlling the
content of a dentist's advertising or sharing professional fees. A number of
states limit the ability of a person other than a licensed dentist to own
equipment or offices used in a dental practice. Some of these states allow
leasing of equipment and office space to a dental practice under a bona fide
lease. Some states also limit the number of offices that may be operated by a
single dentist or dental practice. Federal law and the laws of many states also
prohibit dental practitioners from paying any portion of fees received from
dental services in consideration for the referral of a patient. In addition,
many states impose limits on the tasks that may be delegated by dentists to
dental hygienists or other assistants.
 
   
    The laws regarding fee-splitting and the corporate practice of dentistry and
their interpretation vary from state to state and are enforced by regulatory
authorities with broad discretion. There can be no assurance that the legality
of the Gentle Dental or Dental Care Alliance business or their respective
relationships with affiliated dental practices, or the dentists owning or
employed by such practices, will not be successfully challenged or that the
enforceability of the provisions of any management agreement will not be
limited.
    
 
   
    STATE AND FEDERAL FRAUD AND ABUSE, ANTI-KICKBACK AND ANTI-REFERRAL
LAWS.  The applicability of federal and state laws relating to fraud and abuse,
kickbacks and referrals to transactions or arrangements in the health care
industry, such as those to which Gentle Dental or Dental Care Alliance is or may
be a party, has been the subject of limited judicial interpretation. There can
be no assurance that judicial or administrative authorities will not find that
such laws prohibit the manner in which Gentle Dental and Dental Care Alliance
currently operate, which could have a material adverse effect on the new
company's business, financial condition or results of operations. In particular,
there can be no assurance that federal or state laws relating to kickbacks,
referrals or fee-splitting will not be construed as prohibiting the compensation
of a dental practice manager based on a percentage of a managed practice's
income or revenues.
    
 
                                       16

    Federal law prohibits the offer, payment, solicitation or receipt of any
form of remuneration in return for or in order to induce:
    
 
   
    - the referral of a person for services;
    
 
   
    - the furnishing or arranging for the furnishing of items or services; or
    
 
    - the purchase, lease or order or arranging or recommending purchasing,
      leasing or ordering of any item, reimbursable or otherwise covered under
      Medicare, Medicaid or other federal and state health care programs.
 
These provisions apply to dental services covered under the Medicaid program in
which Gentle Dental and Dental Care Alliance participate. The federal government
has increased scrutiny of joint ventures and other transactions among health
care providers in an effort to reduce potential fraud and abuse related to
Medicare and Medicaid costs. Many states have similar anti-kickback laws, and in
many cases these laws apply to services or items provided to all types of
patients, not just Medicare and Medicaid beneficiaries.
 
   
    Under current federal law, a physician or dentist is prohibited from
referring Medicare or Medicaid patients for the provision of "designated health
services" by any entity in which the physician or dentist has an ownership or
investment interest, including the physician's or dentist's own group practice,
unless an applicable exception is available. The designated health services
include the provision of:
    
 
   
    - clinical laboratory services, radiology and other diagnostic services
      (including ultrasound services);
    
 
   
    - radiation therapy services;
    
 
   
    - physical and occupational therapy services;
    
 
   
    - durable medical equipment;
    
 
   
    - parenteral and enteral nutrients, equipment and supplies;
    
 
   
    - prosthetics, orthotics and prosthetic devices;
    
 
   
    - outpatient prescription drugs;
    
 
   
    - home health services; and
    
 
    - inpatient and outpatient hospital services.
 
    A number of states also have similar laws that prohibit referrals by
physicians, dentists or other health care providers for a broad range of
services (including x-rays) to all patients (not just patients covered by
Medicare, Medicaid or other governmentally sponsored health care plans) if the
dentist, physician or other health care provider has certain enumerated
financial relationships with the entity receiving the referral, unless an
exception applies. Such prohibitions could restrict our ability to integrate
affiliated dental practices and carry out the development of our combined
network of affiliated dental practices.
 
    Noncompliance with, or violation of, either the anti-kickback provisions or
restrictions on referrals can result in exclusion from the Medicare and Medicaid
programs as well as civil and criminal penalties. Similar penalties apply for
violations of state law. We make every effort to comply with the anti-kickback
and anti-referral laws. However, if such laws were construed in a manner that
prohibits the operations of Gentle Dental or Dental Care Alliance or the
affiliated practices, the new company's business, financial condition and
results of operations could be materially adversely affected.
 
    STATE INSURANCE LAWS AND REGULATIONS.  There are certain regulatory risks
associated with negotiating and administering managed care and capitation
contracts. The application of state insurance laws to reimbursement arrangements
is an unsettled area of law and is subject to interpretation by regulators with
broad discretion. As Gentle Dental or Dental Care Alliance or the affiliated
dental practices contract with third-party payors for certain
non-fee-for-service arrangements, we may become subject to state insurance laws.
In the event that we are determined to be engaged in the business of insurance,
we could be required
 
                                       17
<PAGE>
either to seek licensure as an insurance company or to change the form of our
relationships with third-party payors and may become subject to regulatory
enforcement actions. In such event, the new company's business, financial
condition and results of operations may be materially adversely affected.
 
   
    Dedicated Dental Systems, Inc., a wholly-owned subsidiary of Gentle Dental,
operates under a license issued by the California Department of Corporations
under the California Knox-Keene Act Health Care Service Plan Act of 1975. The
Knox-Keene Act and the regulations promulgated thereunder subject entities which
are licensed as healthcare service plans in California to substantial regulation
by the California Department of Corporations. In addition, licensees under the
Knox-Keene Act are required to:
    
 
   
    - file periodic financial data and other information (which generally become
      available to the public);
    
 
   
    - maintain substantial tangible net equity on their balance sheets; and
    
 
    - maintain adequate levels of medical, financial and operating personnel
      dedicated to fulfilling the licensee's statutory and regulatory
      requirements.
 
    The California Department of Corporations is empowered by law to take
enforcement actions against licensees that fail to comply with such
requirements. Any material non-compliance with the Knox-Keene Act and the
regulations promulgated thereunder, could have a material adverse effect on the
new company's business, financial condition and results of operations.
 
   
    Managed Dental Care of Oregon, Inc., and Capitol Dental Care, Inc., each a
wholly owned subsidiary of Gentle Dental, provide capitated dental services
under the Oregon Health Plan pursuant to contracts with the State of Oregon
Office of Medical Assistance Programs. Both Managed Dental Care and Capitol
Dental Care are subject to substantial regulation by the Office of Medical
Assistance Programs with respect to all aspects of their operations. By
regulation, and pursuant to their contracts with the Office of Medical
Assistance Programs, Managed Dental Care and Capitol Dental Care are required
to:
    
 
   
    - maintain sound financial management procedures;
    
 
   
    - maintain protections against insolvency;
    
 
   
    - generate periodic financial reports for submission to the Office of
      Medical Assistance Programs;
    
 
   
    - establish and maintain restricted reserve funds; and
    
 
    - maintain net worth in contractually specified amounts.
 
   
    Failure to meet these requirements is grounds for termination of a contract.
The contracts may also be terminated if funding for the Oregon Health Plan from
federal, state or other sources is not obtained, or is withdrawn, reduced or
limited. Each contract has a one-year term, and there is no guarantee that it
will be renewed or extended. Further, the combined annual revenue generated by
Managed Dental Care and Capitol Dental Care account for approximately 12.3% of
the new company's pro forma revenues for the year ended December 31, 1997 and
approximately 10.4% of its pro forma revenues for the nine months ended
September 30, 1998. Default under either Managed Dental Care's or Capitol Dental
Care's contract with the Office of Medical Assistance Programs, a reduction or
elimination of federal, state or other funding or a refusal to renew or extend
one or both of the contracts could have a material adverse effect on the new
company's business, financial condition and results of operations.
    
 
    REFORM INITIATIVES.  The United States Congress and state legislatures have
considered various types of health care reform, including comprehensive
revisions to the current health care system. It is uncertain what legislative
proposals will be adopted in the future, if any, or what actions federal or
state legislatures or third-party payors may take in anticipation of or in
response to any health care reform proposals or legislation. Health care reform
legislation adopted by Congress or the legislatures of states in which we do
business, downward pressure on reimbursement amounts paid by governmental
payors, dependence on the appropriations process for payment by such payors, as
well as changes in federal and state regulations could have a material adverse
effect on our operations. Changes in the health care industry, such as the
 
                                       18
<PAGE>
growth of managed care organizations and provider networks, may result in lower
payment levels for the services of dentists and lower profitability for our
affiliated dental practices which could have a material adverse effect on the
new company's business, financial condition and results of operations.
 
   
WE ARE SUBJECT TO THE RISK OF LAWSUITS RELATED TO OUR AFFILIATIONS WITH DENTAL
  PRACTICES
    
 
   
    In recent years, dentists have become subject to an increasing number of
lawsuits alleging malpractice and related legal theories. Due to the nature of
our business, we may from time to time become involved as a defendant in
malpractice lawsuits brought against affiliated dental practices or dentists
employed by affiliated dental practices. In addition, we could be involved in
litigation in which it is alleged that we have been negligent in performing our
duties under our management agreements. Gentle Dental and Dental Care Alliance
maintain professional and general liability insurance in amounts deemed
appropriate based upon assessment of historical claims and the nature and risks
of our business. There can be no assurance, however, that an existing or future
claim or claims will not exceed the limits of available insurance coverage, that
any insurer will remain solvent and able to meet its obligations to provide
coverage for any such claim or claims, or that such coverage will continue to be
available or available with sufficient limits and at a reasonable cost to insure
adequately and economically our operations in the future. A judgment against us
that exceeds our insurance coverage could have a material adverse effect on the
new company's business, financial condition and results of operations.
    
 
   
WE ARE SUBJECT TO RISKS RELATED TO OUR GEOGRAPHIC CONCENTRATION
    
 
    Our growth strategy contemplates affiliation with or development of dental
practices in selected geographic markets. This strategy of focused expansion
within selected markets increases the risk that adverse economic or regulatory
developments in one or more of these markets may have a material adverse effect
on the new company's business, financial condition and results of operations. In
addition, we are subject to a broad range of antitrust laws that prohibit
anti-competitive conduct, including price fixing, concerted refusals to deal and
divisions of markets. Among other things, these laws may limit our ability to
enter into management agreements with separate practice groups that compete with
one another in the same geographic market. These laws may also prevent
affiliations of dental practices if such affiliations substantially lessen
competition or tend to create a monopoly.
 
   
SHARES ELIGIBLE FOR FUTURE SALE COULD ADVERSELY AFFECT OUR STOCK PRICE AND
  ABILITY TO RAISE CAPITAL
    
 
   
    Sales of substantial amounts of the new company's common stock in the public
market, or the availability of such shares for future sale, could adversely
affect the market price of the new company's common stock and could impair its
ability to raise additional capital by offering its equity securities. Of the
20,715,607 shares of its common stock that we expect to be outstanding following
the mergers, 11,088,339 shares will be "restricted securities" as defined in
Rule 144 under the Securities Act of 1933, as amended, or will be restricted
under Rule 145 of such Act. All other shares are or will be freely tradable
under federal securities laws. Holders of         shares of the new company's
common stock, including shares underlying certain options that can be converted
into or exercised for its common stock, are entitled to certain rights with
respect to the registration of such shares under the Securities Act of 1933, as
amended. Following the mergers, the new company also expects to register an
aggregate of 2,417,500 shares reserved for past or future option grants under
the Securities Act of 1933, as amended.
    
 
   
NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
    
 
   
    Although the common stock of Gentle Dental and Dental Care Alliance are
currently publicly traded on the Nasdaq SmallCap Market-Registered Trademark-
and the Nasdaq National Market, respectively, there is currently no public
market for the new company's common stock. In connection with the mergers, the
new company has applied to the Nasdaq National Market-Registered Trademark- for
listing of its common stock. However, there can be no assurance that an active
public market for the common stock will develop after the mergers are complete
or, if a trading market does develop, that it will continue or that stockholders
will be able to resell their shares, if at all, without considerable delay or
impact on the sales price. The market price of the new
    
 
                                       19
<PAGE>
company's common stock could be subject to significant fluctuations in response
to variations in financial results or announcements of material events by the
new company or its competitors. Quarterly operating results of the new company,
changes in general conditions in the economy or the dental services industry, or
other developments affecting the new company or its competitors, could cause the
market price of its common stock to fluctuate substantially. In addition, the
equity markets have, on occasion, experienced significant price and volume
fluctuations that have affected the market prices for many companies' securities
and that have often been unrelated to the operating performance of these
companies. Concern about the potential effects of health care reform measures
has contributed to the volatility of stock prices of companies in health care
and related industries and may similarly affect the price of the new company's
common stock following the mergers.
 
CERTAIN ANTI-TAKEOVER PROVISIONS
 
   
    Several provisions of the Delaware General Corporation Law, as well as the
new company's Certificate of Incorporation and By-Laws may make a change in
control more difficult to effect, even if in the stockholders' interest. The new
company's By-Laws will provide for a classified board and its Certificate of
Incorporation will allow its Board of Directors to determine the terms of
preferred stock which may be issued by the new company without approval of the
holders of its common stock, and thereby enables the Board of Directors to
inhibit the ability of the holders of the new company's common stock to effect a
change of control of the new company.
    
 
YEAR 2000 RISKS AND PREPAREDNESS
   
    Many existing computer programs use only two digits to identify a year in a
data field. These programs were designed and developed without considering the
impact of the upcoming change in the century. If not corrected, many computer
applications could fail or create erroneous results by or at the Year 2000 or
earlier. The Year 2000 issue affects us in that our business is dependent on
information technology, such as management information systems, financial and
accounting systems, and other equipment systems that may have Y2K related
problems. Based upon confirmations received from significant management
information systems, financial and accounting systems software licensors, and
other equipment systems that may have Y2K related problems are currently Year
2000 compliant or are expected to be Year 2000 compliant by June 1999. We are in
the process of verifying that our other information technology systems will be
Year 2000 compliant. We expect that we will incur internal staff costs as well
as consulting and other expenses related to Year 2000 system preparations. The
failure of our information technology systems to be Year 2000 compliant could
have a material adverse effect on the new company's business, financial
condition or results of operations.
    
 
   
    We also have certain material relationships with vendors and third-party and
governmental payors who also are dependent on information technology systems. We
have contacted or intend to contact these vendors, third-party and governmental
payors and other third parties with whom we have material relationships to
ensure Year 2000 compliance. Certain of our significant vendors have confirmed
to us that they are or expect to be Year 2000 compliant. However, we anticipate
that many third-party and governmental payors and our smaller vendors may not be
Year 2000 compliant. While we do not expect the noncompliance of our smaller
vendors will have a material adverse effect on Wisdom Holdings' business,
financial condition or results of operations, the noncompliance of any of our
significant vendors, third-party or governmental payors could have a material
adverse effect on Wisdom Holdings' business, financial condition or results of
operations.
    
 
   
    Although we believe that the steps we are taking will be adequate to ensure
that we will not be materially affected by the Year 2000 problem, there can be
no assurance that these actions will protect us from the risks associated with
the Year 2000 problem. The analysis of, and preparation for, the Year 2000 and
related problems necessarily rely on a variety of assumptions about future
events, and there can be no assurance that we will accurately predict which
future events or that any remedial and contingency plans that may be adopted
will adequately address such future events. See "Information About Gentle
Dental-- Year 2000 Compliance" and "Information About Dental Care Alliance--Year
2000 Compliance."

                                  THE MEETINGS
                         GENTLE DENTAL SPECIAL MEETING
 
GENERAL
 
   
    This document is first being mailed by Gentle Dental to the holders of its
common stock and preferred stock on or about            , 1999, and is
accompanied by the notice of the special meeting of shareholders of Gentle
Dental and a form of proxy that is solicited by the Board of Directors of Gentle
Dental for use at the Gentle Dental special meeting to be held on            ,
1999, at   a.m., local time,           , El Segundo, California, and at any
adjournments or postponements thereof.
    
 
MATTERS TO BE CONSIDERED
 
   
    At the Gentle Dental special meeting, Gentle Dental shareholders will be
asked to consider and vote on the proposal to approve an Agreement and Plan of
Reorganization and Merger, dated as of October 15, 1998, as amended, by and
among Wisdom Holdings, Inc., Wisdom Holdings Acquisition Corp. I, Wisdom
Holdings Acquisition Corp. II, Gentle Dental and Dental Care Alliance, and the
transactions contemplated thereby, and any such other matters as may properly be
submitted to a vote at the Gentle Dental special meeting. A copy of the merger
agreement is attached as APPENDIX A. Gentle Dental shareholders may also be
asked to vote upon a proposal to adjourn or postpone the Gentle Dental special
meeting, which adjournment or postponement could be used for the purpose, among
others, of allowing additional time for the soliciting of additional votes to
approve the merger agreement and the transactions contemplated thereby.
    
 
PROXIES
 
   
    The accompanying form of proxy is for use at the Gentle Dental special
meeting if a Gentle Dental shareholder will be unable or does not wish to attend
in person. A Gentle Dental shareholder may revoke his or her proxy and reclaim
his or her right to vote up to and including the date of the meeting. To do so,
submit to the Secretary of Gentle Dental a properly executed proxy of a later
date or written notice revoking the proxy, or attend the Gentle Dental special
meeting and vote in person. Written notices of revocation and other
communications with respect to the revocation of Gentle Dental proxies should be
addressed to Gentle Dental Service Corporation, 222 North Sepulveda Boulevard,
Suite 740, El Segundo, California 90245-4340, Attention: Corporate Secretary.
All shares represented by valid proxies received pursuant to this solicitation,
and not revoked before they are exercised, will be voted in the manner specified
therein. If nothing is specified, the proxies will be voted in favor of the
approval of the merger agreement and the transactions contemplated thereby. The
Gentle Dental Board of Directors is unaware of any other matters that may be
presented for action at the Gentle Dental special meeting. If other matters do
properly come before the Gentle Dental special meeting, however, it is intended
that shares represented by proxies will be voted in the discretion of the
proxyholders, provided that no proxy that has been voted against approval and
adoption of the merger agreement will be voted in favor of any adjournment or
postponement of the Gentle Dental special meeting for the purpose of soliciting
additional proxies.
    
 
SOLICITATION OF PROXIES
 
    The entire cost of soliciting the proxies from the Gentle Dental
shareholders will be borne by Gentle Dental. In addition to the solicitation of
the proxies by mail, Gentle Dental will request banks, brokers and other record
holders to send proxies and proxy material to the beneficial owners of the stock
and secure their voting instructions, if necessary. Gentle Dental will reimburse
such record holders for their reasonable expenses in so doing. If necessary,
Gentle Dental may use several of its regular employees, who will not be
specially compensated, to solicit proxies from shareholders, either personally
or by telephone, telegram, facsimile, or special delivery letter.
 
                                       21
<PAGE>
RECORD DATE AND VOTING RIGHTS
 
   
    Pursuant to the provisions of the Washington Business Corporation Act, and
the rules of the Nasdaq Small Cap Market, December 7, 1998 has been fixed as the
record date for determination of Gentle Dental shareholders entitled to notice
of and to vote at the Gentle Dental special meeting. Holders of shares of Gentle
Dental capital stock of record that are such holders at the close of business on
the Gentle Dental record date will be entitled to notice of and to vote on all
matters at the Gentle Dental special meeting. In addition, holders of Gentle
Dental Series A preferred stock and Gentle Dental Series C preferred stock at
the Gentle Dental record date will be entitled to notice of and to vote at the
Gentle Dental special meeting regarding the merger agreement and the
transactions contemplated thereby. At the close of business on the Gentle Dental
record date, there were      shares of Gentle Dental common stock outstanding
held by approximately       holders of record, 100 shares of Gentle Dental
Series A preferred stock held by one holder of record, 100 shares of Gentle
Dental Series C preferred stock held by one holder of record and       shares of
Gentle Dental Series D preferred stock held by       holders of record. The
presence, in person or by proxy, of shares of Gentle Dental capital stock
representing a majority of such shares considered as a single class, outstanding
and entitled to vote on the Gentle Dental record date is necessary to constitute
a quorum at the Gentle Dental special meeting.
    
 
   
    Shares of Gentle Dental capital stock present in person at the Gentle Dental
special meeting but not voting, and shares of Gentle Dental Capital Stock for
which Gentle Dental has received proxies but with respect to which holders of
such shares have abstained, will be counted as present at the Gentle Dental
special meeting for purposes of determining the presence or absence of a quorum
for the transaction of business. Brokers who hold shares of Gentle Dental common
stock in nominee or "street" name for customers who are the beneficial owners of
such shares are prohibited from giving a proxy to vote shares held for such
customers with respect to the matters to be voted upon at the Gentle Dental
special meeting without specific instructions from such customers. Shares
represented by proxies returned by a broker holding such shares in "street" name
will be counted for purposes of determining whether a quorum exists, even if
such shares are not deemed "broker non-votes" because they are voted in matters
where discretionary voting by the broker is not allowed under applicable laws.
    
 
   
    The affirmative vote of a majority of the outstanding shares of Gentle
Dental common stock and Gentle Dental Series D preferred stock entitled to vote,
voting together as single class, is required to approve the merger agreement and
the transactions contemplated thereby. In addition, the vote of a majority of
the outstanding shares of each of the Gentle Dental Series A preferred stock,
Gentle Dental Series C preferred stock and Gentle Dental Series D preferred
stock entitled to vote, voting as separate classes, is required to approve the
merger agreement and the transactions contemplated thereby. Each share of Gentle
Dental capital stock is entitled to one vote regarding the merger agreement and
the transactions contemplated thereby.
    
 
   
    ABSTENTIONS AND BROKER NON-VOTES WILL HAVE THE SAME EFFECT AS VOTES AGAINST
APPROVAL OF THE MERGER AGREEMENT. ACCORDINGLY, THE GENTLE DENTAL BOARD OF
DIRECTORS URGES GENTLE DENTAL SHAREHOLDERS TO COMPLETE, DATE AND SIGN THE
ACCOMPANYING PROXY AND RETURN IT PROMPTLY IN THE ENCLOSED, POSTAGE-PAID
ENVELOPE.
    
 
   
    As of the Gentle Dental record date, directors and executive officers of
Gentle Dental beneficially owned      shares of Gentle Dental common stock,
representing approximately    % of the common stock entitled to vote, 100 shares
of Gentle Dental Series A preferred stock, representing all of the Series A
preferred stock entitled to vote, 100 shares of Gentle Dental Series C preferred
stock, representing all of the Gentle Dental Series C preferred stock entitled
to vote, and       shares of Gentle Dental Series D preferred stock,
representing approximately    % of the Gentle Dental Series D preferred stock
entitled to vote. It is currently expected that each such director and executive
officer of Gentle Dental will vote the shares of Gentle Dental capital stock
beneficially owned by him or her which such director or officer is entitled to
vote for approval of the Agreement and the transactions contemplated thereby.

Shareholders" on page 77.
    
 
   
RECOMMENDATION OF GENTLE DENTAL BOARD OF DIRECTORS
    
 
   
    The Gentle Dental Board of Directors has approved the merger agreement and
the transactions contemplated thereby. The Gentle Dental Board of Directors
believes that the merger agreement and the transactions contemplated thereby are
in the best interests of Gentle Dental and the Gentle Dental shareholders and
recommends that the Gentle Dental shareholders vote "FOR" approval of the merger
agreement and the transactions contemplated thereby. See "The
Mergers--Recommendation of the Gentle Dental Board and Reasons for the Mergers"

accountants of Gentle Dental, will be present at the Gentle Dental special
meeting to respond to appropriate questions raised at such meeting.
    
 
                      DENTAL CARE ALLIANCE SPECIAL MEETING
 
GENERAL
 
   
    This document is first being mailed by Dental Care Alliance to the holders
of its common stock on or about            , 1999, and is accompanied by the
notice of the Dental Care Alliance special meeting and a form of proxy that is
solicited by the Board of Directors of Dental Care Alliance for use at the
special meeting of Dental Care Alliance stockholders to be held on            ,
           , 1999, at    a.m., local time, at             , Sarasota, Florida,
and at any adjournments or postponements thereof.
    
 
MATTERS TO BE CONSIDERED
 
   
    The purpose of the Dental Care Alliance special meeting is to take action
with respect to the approval of the merger agreement and the transactions
contemplated thereby and any such other matters as may be properly submitted to
a vote at the Dental Care Alliance special meeting. A copy of the merger
agreement is attached as APPENDIX A. Dental Care Alliance stockholders may also
be asked to vote upon a proposal to adjourn or postpone the Dental Care Alliance
special meeting, which adjournment or postponement could be used for the
purpose, among others, of allowing additional time for the solicitation of
additional votes to approve the merger agreement and the transactions
contemplated thereby.
    
 
PROXIES
 
   
    The accompanying form of proxy is for use at the Dental Care Alliance
special meeting if a Dental Care Alliance stockholder will be unable to attend
in person. A Dental Care Alliance stockholder may revoke his or her proxy and
reclaim his or her right to vote up to and including the date of the meeting. To
do so, submit to the Secretary of Dental Care Alliance a properly executed proxy
of a later date or written notice revoking the proxy or attend the Dental Care
Alliance special meeting and vote in person. Written notices of revocation and
other communications with respect to the revocation of Dental Care Alliance
proxies should be addressed to Dental Care Alliance, Inc., 1343 Main Street, 7th
Floor, Sarasota, Florida 34236, Attention: Corporate Secretary. All shares
represented by valid proxies received pursuant to this solicitation, and not
revoked before they are exercised, will be voted in the manner specified
therein. If nothing is specified, the proxies will be voted in favor of approval
of the merger agreement and the transactions contemplated thereby. The Dental
Care Alliance Board of Directors is unaware of any other
    
 
                                       23
<PAGE>
   
matters that may be presented for action at the Dental Care Alliance special
meeting. If other matters do properly come before the Dental Care Alliance
special meeting, however, it is intended that shares represented by proxies will
be voted in the discretion of the proxy holders, provided that no proxy that is
voted against approval and adoption of the merger agreement will be voted in
favor of any adjournment or postponement of the Dental Care Alliance special
meeting for the purpose of soliciting additional proxies.
    
 
SOLICITATION OF PROXIES
 
    The entire cost of soliciting the proxies from the Dental Care Alliance
stockholders will be borne by Dental Care Alliance. In addition to the
solicitation of the proxies by mail, Dental Care Alliance will request banks,
brokers and other record holders to send proxies and proxy material to the
beneficial owners of the stock and secure their voting instructions, if
necessary. Dental Care Alliance will reimburse such record holders for their
reasonable expenses in so doing. If necessary, Dental Care Alliance may use
several of its regular employees, who will not be specially compensated, to
solicit proxies from Dental Care Alliance stockholders, either personally or by
telephone, telegram, facsimile or special delivery letter.
 
RECORD DATE AND VOTING RIGHTS
 
   
    Pursuant to the provisions of the Delaware General Corporation Law, the
Dental Care Alliance By-laws, as amended, and the rules of the Nasdaq National
Market, December 8, 1998 has been fixed as the record date for determination of
Dental Care Alliance stockholders entitled to notice of and to vote at the
Dental Care Alliance special meeting. Accordingly, only Dental Care Alliance
stockholders of record at the close of business on the Dental Care Alliance
record date will be entitled to notice of and to vote at the Dental Care
Alliance special meeting. At the close of business on the Dental Care Alliance
record date, there were 7,031,197 shares of Dental Care Alliance common stock
outstanding held by approximately         holders of record. The presence, in
person or by proxy, of shares of Dental Care Alliance common stock representing
a majority of such shares outstanding and entitled to vote on the Dental Care
Alliance record date is necessary to constitute a quorum at the Dental Care
Alliance special meeting.
    
 
   
    Shares of Dental Care Alliance common stock present in person at the Dental
Care Alliance special meeting but not voting, and shares of Dental Care Alliance
common stock for which Dental Care Alliance has received proxies but with
respect to which holders of such shares have abstained, will be counted as
present at the Dental Care Alliance special meeting for purposes of determining
the presence or absence of a quorum for the transaction of business. Brokers who
hold shares of Dental Care Alliance common stock in nominee or "street" name for
customers who are the beneficial owners of such shares are prohibited from
giving a proxy to vote shares held for such customers with respect to the
matters to be considered and voted upon at the Dental Care Alliance special
meeting without specific instructions from such customers. Broker non-votes will
be counted for purposes of determining whether a quorum exists.
    
 
   
    The affirmative vote of the holders of a majority of the outstanding shares
of Dental Care Alliance common stock entitled to vote is required to approve the
merger agreement and the transactions contemplated thereby. Each share of Dental
Care Alliance common stock is entitled to one vote.
    
 
   
    ABSTENTIONS AND BROKER NON-VOTES WILL HAVE THE SAME EFFECT AS VOTES AGAINST
SUCH APPROVAL AND ADOPTION. ACCORDINGLY, THE DENTAL CARE ALLIANCE BOARD OF
DIRECTORS URGES DENTAL CARE ALLIANCE STOCKHOLDERS TO COMPLETE, DATE AND SIGN THE
ACCOMPANYING PROXY AND RETURN IT PROMPTLY IN THE ENCLOSED POSTAGE-PAID ENVELOPE.
    
 
   
    As of the Dental Care Alliance record date, directors and executive officers
of Dental Care Alliance beneficially owned 2,205,579 shares of Dental Care
Alliance common stock, representing approximately    % of common stock entitled
to vote. It is currently expected that each such director and executive officer
of Dental Care Alliance will vote the shares of Dental Care Alliance common
stock beneficially owned by him or her which such director or officer is
entitled to vote for approval of the merger agreement and the transactions
contemplated thereby.

Dental Care Alliance will become wholly-owned subsidiaries of Wisdom Holdings.
    
 
   
BACKGROUND OF THE MERGERS
    
 
   
    The managements of Gentle Dental and Dental Care Alliance have, from time to
time, considered the possibility of acquisitions and strategic combinations with
other dental practice management companies and their potential strategic fit
with such companies based on the following considerations:
    
 
   
    - the businesses conducted thereby;
    
 
   
    - economic considerations;
    
 
   
    - their management and employee cultures; and
    
 
   
    - the geographic location and breadth of their businesses.
    
   
    Since Dental Care Alliance's initial public offering in November 1997,
Dental Care Alliance has had a number of conversations with companies in the
dental practice management industry to discuss potential business combinations
with prospective strategic partners. The Dental Care Alliance Board of Directors
believed that Dental Care Alliance's planned expansion of its business could be
enhanced significantly through strategic combinations with appropriate existing
dental practice management companies. The Dental Care Alliance Board of
Directors also believed that there would be a trend toward increasing
consolidation within the dental practice management industry. Dental Care
Alliance's acquisition in December 1997 of Marketplace Dental, Inc., a dental
practice management company with six practices under management at the time of
the acquisition, exemplified its beliefs.
    
 
   
    From January to July 1998, and prior to meeting with management of Gentle
Dental, Dental Care Alliance's management and Raymond James & Associates, Inc.
met with management of six dental practice management companies to discuss
potential business combinations. One discussion terminated because no agreement
could be reached as to relative valuations. One discussion terminated because
Dental Care Alliance determined that if it were to enter into a business
combination with this company, it would not be able to pool the operating
results of that company with its own, and that such a transaction would be
dilutive to Dental Care Alliance's earnings. Two transactions were not pursued
as the companies were not profitable and the business combinations would have
been dilutive to Dental Care Alliance's earnings. Discussions with another
company stopped because of potential management integration
    
 
                                       26
<PAGE>
   
problems and differences in business philosophy. Dental Care Alliance's
management suspended discussion with the sixth potential company as a result of
an anticipated acquisition by that company which was expected to result in a
change of management and other changes to the company's operations. No
discussions are ongoing at this time.
    
 
   
    On July 15, 1998, Mr. Fiore, Dr. Matzkin and certain members of the Boards
of Directors of Gentle Dental and Dental Care Alliance met informally to discuss
issues effecting the industry, the companies and their respective businesses,
their perception of consolidation within the industry and the benefits of
strategic combinations. At a board meeting held the same day, Dental Care
Alliance's Board of Directors was advised of preliminary discussions. Mr. Fiore
and Dr. Matzkin met again on July 20, 1998 to further discuss the businesses of
Gentle Dental and Dental Care Alliance and to pursue the possibility of a
strategic alliance between the companies. As a result of these meetings, the
companies preliminarily determined that a combination could be beneficial to
each of them and their respective stockholders in view of the characteristics of
the companies' business and geographic locations, the accelerating trend toward
consolidation in the industry generally and the larger company that would be
created as a result of the combination. In order to facilitate further
discussions between the two companies, Gentle Dental and Dental Care Alliance
entered into a standard form confidentiality agreement on July 24, 1998. To
assist with negotiation and analysis of the proposed combination of the two
companies, Gentle Dental and Dental Care Alliance retained Salomon Smith Barney
Inc. and Raymond James & Associates, Inc. as their financial advisors,
respectively.
    
 
   
    On August 17, 1998, Dr. Matzkin visited Gentle Dental's corporate
headquarters in El Segundo, California, and met with Mr. Fiore to further
discuss the potential combination of the companies. As part of the meetings and
discussions, Dr. Matzkin also visited the offices of four dental practices
managed by Gentle Dental to gain additional understanding of Gentle Dental's
management relationship with its affiliated dental practices. On August 25,
1998, certain directors and members of senior management of the companies and
their respective investment advisors met at Dental Care Alliance's corporate
headquarters in Sarasota, Florida, to discuss issues relating to the potential
business combination of the two companies and began discussions regarding the
terms and structure of a proposed transaction.
    
 
    Over a period of three days in early September 1998, certain members of
senior management of Dental Care Alliance met with certain members of senior
management of Gentle Dental, at Gentle Dental's corporate headquarters, to
conduct due diligence and to visit additional dental offices managed by Gentle
Dental. Over this period, members of Dental Care Alliance's senior management
also reviewed Gentle Dental's material contracts, including material acquisition
agreements. Over an additional three day period later in September 1998, certain
members of Gentle Dental's senior management met with certain members of Dental
Care Alliance's senior management at Dental Care Alliance's corporate
headquarters to conduct due diligence on Dental Care Alliance and to visit
certain dental offices managed by Dental Care Alliance. Over this period,
members of Gentle Dental's senior management also reviewed Dental Care
Alliance's material contracts, including material acquisiton agreements.
 
   
    Following the due diligence investigation and office visits conducted by the
companies, members of senior management of both Gentle Dental and Dental Care
Alliance met with each other and their respective investment advisors on
September 22nd, 23rd and 24th at the New York offices of the Sprout Group to
finalize their discussions regarding the terms and structure of the proposed
combination transaction between the two companies. In addition to all these
meetings, numerous discussions were held telephonically.
    
 
   
    During September 1998, management of the two companies continued business
due diligence and senior management for each company reported its findings to
its Boards of Directors. As the results of this due diligence were favorable,
each company's board of directors decided to pursue negotiations.
    
 
   
    Throughout early October 1998, Mr. Fiore and Dr. Matzkin negotiated terms of
definitive agreements documenting the proposed combination of the two companies
and each routinely briefed members of their boards of directors and senior
management as to the status of the negotiations. During this period, legal
advisors for each of Gentle Dental and Dental Care Alliance conducted legal due
diligence on the other
    
 
                                       27
<PAGE>
   
company. As part of the negotiation process, management and the Board of
Directors of each of Gentle Dental and Dental Care Alliance considered how they
would value each company for purposes of the mergers. Because the common shares
of neither company were consistently traded in significant volume, the parties
believed that the market price of each respective company's common shares was
not an accurate indicator of the company's value. Instead, the parties agreed to
a fixed ratio for exchange of the shares of each company with the new company
based on, among other things, their relative earnings. The parties considered
the potential negative aspects of having a fixed exchange ratio, such as the
exchange ratio would not be adjusted to account for the fact that subsequent
changes in earnings levels or market value. However, management and the Boards
of Directors of Gentle Dental and Dental Care Alliance acknowledged that each
company expected to grow its relative revenues by additional affiliations with
dental practices prior to the consummation of the mergers. The parties believed
that a fixed ratio would be less complicated and more consistent with their view
that future acquisitions should benefit the stockholders of the new company,
rather than only Gentle Dental's or Dental Care Alliance's stockholders.
    
 
   
    On October 13, 1998, the Board of Directors of Dental Care Alliance met to
discuss and review the terms of the proposed business combination and the
various transactions contemplated as a result of the combination. The Dental
Care Alliance Board of Directors did not reach a final decision in its October
13 meeting, and scheduled a meeting to be held on October 15, 1998, to further
review the terms of the proposed combination.
    
 
   
    On October 14, 1998, members of the Gentle Dental Board of Directors met to
review the terms of the proposed business combination and to discuss the various
transactions contemplated by the proposed combination. The Gentle Dental Board
of Directors reviewed in detail the terms of the proposed combination, the due
diligence investigation undertaken by Gentle Dental (with the assistance of
legal counsel and Salomon Smith Barney Inc.) and the fairness opinion provided
by Salomon Smith Barney Inc. regarding the fairness to Gentle Dental of the
ratio of exchange of the common shares of Dental Care Alliance for common shares
of Wisdom Holdings, as contemplated by the merger agreement. The Gentle Dental
Board of Directors also considered certain concerns raised by one of Gentle
Dental's officers who is a director, the "dissenting director," as to, among
other things, the due diligence investigation and information considered by the
Gentle Dental Board of Directors in connection with the mergers, and the
valuation of Dental Care Alliance. After a discussion and review of the terms of
the merger agreement and the related documents previously presented to the
Gentle Dental Board of Directors, the Gentle Dental Board of Directors (with the
dissenting director dissenting) approved and authorized the execution of the
merger agreement and the related agreements and transactions contemplated by the
merger agreement. [Following the October 14 meeting, the dissenting director
informed Gentle Dental that he desired to spend more time with his family and
pursue charitable interests and began discussing modification to his employment
relationship with Gentle Dental. See "Information About Gentle Dental--Gentle
Dental's Management's Discussion and Analysis of Financial Condition and Results
of Operations--Certain Transactions Regarding Gentle Dental" at page 75.]
    
 
   
    On October 15, 1998, the Dental Care Alliance Board of Directors met several
times to keep updated as to the merger negotiations and to discuss and review
the terms of the proposed business combination. The Dental Care Alliance Board
of Directors also reviewed the fairness opinion provided to Dental Care Alliance
by Raymond James & Associates, Inc. regarding the fairness to the stockholders
of Dental Care Alliance of the ratio of exchange of the common shares of Dental
Care Alliance for common shares of Wisdom Holdings, as contemplated by the
merger agreement. After further discussion and review of the terms of the merger
agreement and the related documents previously presented to the Dental Care
Alliance Board of Directors, the Dental Care Alliance Board of Directors
authorized and approved the execution of the merger agreement and the related
agreements and transactions contemplated by the merger agreement.
    
 
   
    During the evening of October 15, 1998, the parties executed the merger
agreement and the parties announced the proposed business combination on the
morning of October 16, 1998.
    
 
                                       28
<PAGE>
   
    The Gentle Dental Board of Directors held a telephonic meeting on November
13, 1998 to review concerns raised subsequent to the October 14, 1998 board
meeting by the dissenting director regarding the mergers, which concerns were
substantially similar to those addressed at the October 14, 1998 board meeting
but included additional concerns regarding operational issues following the
mergers. Following the November 14 meeting, the dissenting director, with the
assistance of Gentle Dental, continued to review matters pertaining to the
mergers that he felt required further consideration. On December 23, 1998, the
dissenting director informed Gentle Dental that he had completed his review,
that his concerns had been satisfactorily addressed and that he now supports the
proposed mergers. Additionally, the dissenting director executed a Stockholders
Agreement in which he agreed to vote his shares "For" adoption and approval of
the merger agreement.
    
 
   
RECOMMENDATION OF THE GENTLE DENTAL BOARD OF DIRECTORS AND REASONS FOR THE
  MERGERS
    
 
   
    The Gentle Dental Board of Directors believes that the merger agreement is
fair to, and in the best interests of, Gentle Dental and the Gentle Dental
shareholders. Accordingly, the Gentle Dental Board of Directors has approved the
merger agreement, and recommends that the Gentle Dental shareholders vote for
the approval and adoption of the merger agreement, the mergers and the
agreements and transactions contemplated by the merger agreement.
    
 
   
    The Gentle Dental Board of Directors believes that the consummation of the
mergers described in the merger agreement presents a unique opportunity to
create one of the largest dental practice management companies in the United
States, with a significant presence on both the East Coast and the West Coast.
    
 
   
    In reaching its decision to approve the merger agreement, the mergers and
the agreements and transactions contemplated by the merger agreement, the Gentle
Dental Board of Directors consulted with Gentle Dental's management, as well as
with its financial and legal advisors and considered a variety of factors,
including the following positive factors:
    
 
   
    - The Board of Directors' familiarity with and review of Gentle Dental's
      business, operations, financial condition, earnings and prospects.
    
 
   
    - The anticipated effectiveness of the mergers in implementing and
      accelerating Gentle Dental's strategy to become one of the largest dental
      practice management companies in the United States, the depth of its
      management team and the ability of the combined company's management team
      to successfully integrate the operations of Gentle Dental and Dental Care
      Alliance.
    
   
    - The business, operations, financial condition, earnings and prospects of
      Dental Care Alliance. In making its determination, the Board of Directors
      took into account the results of Gentle Dental's due diligence review of
      Dental Care Alliance's business as well as the views of the dissenting
      director. See "--Background of the Mergers."
    
 
   
    - The scale, scope and strength of the operations of the combined company
      relative to Gentle Dental on a stand alone basis, in that the combined
      company would provide improved stability of financial and business
      operations as a result of anticipated increased cash flow and earnings,
      increased access to capital and increased attractiveness to dental
      practices which are affiliation candidates.
    
 
   
    - The structure of the combination and the terms of the merger agreement and
      the Stockholders' Agreements, which were reciprocal in nature, including
      the fact that the fixed ratio for the exchange of shares of Gentle Dental
      for shares of Wisdom Holdings provides certainty as to the number of
      shares of Wisdom Holdings' common stock and preferred stock to be issued
      to Gentle Dental's shareholders in the mergers and that as to Gentle
      Dental the mergers intended to qualify as either a reorganization under
      Section 368(a) of the Internal Revenue Code of 1986, as amended, or as a
      transfer to a controlled corporation qualifying under Section 351 of the
      Code, and for "pooling-of-interests" accounting treatment.
    
 
   
    - The proposed arrangements with existing members of senior management of
      Gentle Dental and Dental Care Alliance, including that Mr. Fiore would
      serve as Co-Chairman of the Board and Chief Executive Officer of the
      combined company after the mergers and Dr. Matzkin would serve as Co-
    
 
                                       29
<PAGE>
   
      Chairman, President and Chief Dental Officer of the combined company after
      the mergers. See "Operations and Management of Wisdom Holdings after the
      Merger."
    
 
   
    - The written opinion of Salomon Smith Barney Inc. that, as of October 15,
      1998, the ratio for the exchange of common shares of Dental Care Alliance
      for common shares of Wisdom Holdings was fair from a financial point of
      view to Gentle Dental. See "--Opinion of Gentle Dental's Financial
      Advisor."
    
 
   
    - The belief of Gentle Dental's senior management and the Board of Directors
      that Gentle Dental and Dental Care Alliance share a compatible business
      culture and that their respective managements possess complementary skills
      and expertise.
    
 
   
    Gentle Dental's Board of Directors also considered certain countervailing
factors in evaluating the mergers. Such countervailing factors included the
following:
    
 
   
    - The expenses and operational difficulties of integrating the
      geographically separated businesses of Gentle Dental and Dental Care
      Alliance.
    
 
   
    - The dilution of Gentle Dentals' shareholders that would occur as a result
      of the proposed merger.
    
 
   
    - The potential negative aspects of a fixed exchange ratio.
    
 
   
    - Dental Care Alliances' lack of a sustained record of growth and
      profitability.
    
 
   
    After considering the above and other possible countervailing factors
associated with the mergers, the Gentle Dental Board of Directors determined
that the perceived benefits of the mergers to its shareholders outweighed those
countervailing factors.
    
 
   
    The foregoing discussion of the information and factors considered by the
Gentle Dental Board of Directors is not intended to be exhaustive but includes
all material factors considered by the Gentle Dental Board of Directors. In
reaching its determination to approve and recommend the mergers, the Board of
Directors did not assign any relative or specific weights to the foregoing
factors, and individual directors may have given differing weights to different
factors. The Gentle Dental Board of Directors recommends that Gentle Dental
shareholders vote for approval and adoption of the merger agreement.
    
 
   
RECOMMENDATION OF THE DENTAL CARE ALLIANCE BOARD OF DIRECTORS AND REASONS FOR
  THE MERGERS
    
 
   
    The Dental Care Alliance Board of Directors has approved and adopted the
merger agreement and believes that as to Dental Care Alliance the mergers are
fair to and in the best interests of Dental Care Alliance and its stockholders.
Accordingly, the Dental Care Alliance Board of Directors has unanimously
approved the merger agreement and unanimously recommends that the stockholders
vote for the approval of the merger agreement and the consummation of the
transactions contemplated thereby. See "Background of the Merger" and "Opinion
of Dental Care Alliance's Financial Advisor."
    
 
   
    The terms of the merger agreement, including the ratio for the exchange of
common shares of Dental Care Alliance for common shares of Wisdom Holdings, are
the result of arm's length negotiations between representatives of Gentle Dental
and Dental Care Alliance. In reaching its decision to approve the merger
agreement, the Dental Care Alliance Board of Directors, with the assistance of
Dental Care Alliance's outside financial and legal advisors, considered the
financial, legal and other aspects of the proposed merger and the fairness of
the ratio for the exchange of common shares of Dental Care Alliance for common
shares of Wisdom Holdings. The Board of Directors concluded that the merger
agreement and the mergers contemplated by the merger agreement are fair to and
in the best interests of Dental Care Alliance and its stockholders. In reaching
its decision to authorize Dental Care Alliance to enter into the merger
agreement and to recommend to its stockholders the adoption of the merger
agreement, the Dental Care Alliance Board of Directors considered a number of
factors, both from a short-term and long-term perspective, including, without
limitation, those set forth in "--Background of the Mergers," "-- Opinion of
Dental Care Alliance's Financial Advisor" and the following:
    
 
    - Information concerning and/or familiarity with the business, results of
      operations, financial condition, competitive position and prospects of
      Dental Care Alliance and Gentle Dental, including the recent trading
      price, volume and price to earnings ratio of each of their common stock,
      their
 
                                       30
<PAGE>
      historical financial data, customary statistical measurements of financial
      performance, potential growth and profitability, both as separate and
      combined entities, and the business risks associated therewith, and the
      future prospects for the combined company's capital stock.
 
    - The fact that Dental Care Alliance's stockholders would receive
      approximately 46.5% of the equity on a fully diluted basis in a company
      that it is estimated will have significantly greater annual revenues than
      Dental Care Alliance would have on a stand alone basis, which would make
      it one of the largest companies in the industry, as opposed to Dental Care
      Alliance's annualized revenues of approximately $50 million.
 
    - The current and prospective environment in which Dental Care Alliance
      operates, including national and local economic conditions, the
      competitive environment for dental practice management companies and other
      similar businesses generally and the perceived trend toward increasing
      consolidation in the industry and the competitive effects of such
      increased consolidation on smaller practice management companies such as
      Dental Care Alliance.
 
   
    - The perceived value to be received by holders of Dental Care Alliance
      common stock pursuant to the merger agreement in relation to the
      historical trading prices of Dental Care Alliance common stock.
    
 
   
    - The financial and other significant terms of the proposed mergers, and the
      review by Dental Care Alliance with its legal and financial advisors of
      the provisions of the merger agreement.
    
 
   
    - The similar management philosophies of Dental Care Alliance and Gentle
      Dental and the officers and directors of Gentle Dental who would remain
      with the new company after the mergers, including the synergistic
      capabilities and complimentary areas of expertise of Dental Care
      Alliance's and Gentle Dental's respective Chief Executive Officers.
    
 
    - The extent to which Dental Care Alliance's executive officers would have
      control over dental practice management for the combined company and
      Dental Care Alliance personnel, as well as provide assistance to Gentle
      Dental's managed practices, while benefiting from economies of scale and
      Gentle Dental's administrative expertise.
 
   
    - The written opinion of Raymond James & Associates, Inc. that, as of the
      date of such opinion, the ratio for the exchange of common shares of
      Dental Care Alliance for common shares of Wisdom Holdings was fair to the
      stockholders of Dental Care Alliance from a financial point of view. See
      "--Opinion of Dental Care Alliance's Financial Advisor."
    
   
    - The Dental Care Alliance Board of Directors' belief that the analyses of
      Raymond James & Associates, Inc. supported the Board of Directors'
      conclusion that as to Dental Care Alliance the mergers are fair to the
      Dental Care Alliance stockholders from a financial point of view. See "--
      Opinion of Dental Care Alliance's Financial Advisor."
    
 
    - The geographic concentration and vertical integration of Gentle Dental's
      dental practices under management, as well as the geographic scope of the
      combined company.
 
   
    - The belief of the Board of Directors that the receipt of the new company's
      common stock in the mergers generally will permit holders of common stock
      to defer any federal income tax liability associated with appreciation of
      the value of their stock (see "--Certain Federal Income Tax Consequences")
      and to become stockholders of the combined company.
    
 
   
    - The alternative strategic courses available to Dental Care Alliance,
      including remaining independent and exploring other potential business
      combination transactions and the potential values that could be derived
      therefrom See "Background of the Mergers".
    
 
   
    Dental Care Alliance's Board of Directors also considered certain
countervailing factors in evaluating the mergers. Such countervailing factors
included the following:
    
 
   
    - Gentle Dental's lack of a sustained record of growth and profitability.
    
 
   
    - The dilution of Dental Care Alliance's stockholders that would occur as a
      result of the proposed merger.
    
 
                                       31
<PAGE>
   
    - The shifting of operational control away from Dental Care Alliance's
      current management and the relocation of the new company's corporate
      headquarters and operations from Florida to California.
    
 
   
    - The potential negative aspects of a fixed exchange ratio.
    
 
   
    In the judgment of the Dental Care Alliance Board of Directors, these
countervailing factors, neither individually nor collectively outweighed the
benefits anticipated to be gained for Dental Care Alliance and its stockholders
from proceeding with the merger.
    
 
   
    In view of the variety of factors considered by the Dental Care Alliance
Board of Directors in connection with its evaluation of the mergers, the Dental
Care Alliance Board of Directors did not find it practicable to, and did not,
quantify or otherwise assign relative weights to the factors listed above.
    
 
OPINION OF GENTLE DENTAL'S FINANCIAL ADVISOR
 
   
    On July 24, 1998, the Gentle Dental Board of Directors retained Salomon
Smith Barney Inc. to act as its financial advisor in connection with a possible
business combination transaction with Dental Care Alliance. In connection with
their engagement, the Gentle Dental Board of Directors instructed Salomon Smith
Barney Inc. to evaluate the fairness, from a financial point of view, to Gentle
Dental of the exchange ratio of the common shares of Dental Care Alliance for
common shares of Wisdom Holdings. At the October 14, 1998 meeting of the Gentle
Dental Board of Directors, Salomon Smith Barney Inc. delivered an oral opinion
(which opinion was subsequently confirmed by delivery of a written opinion dated
October 15, 1998) to the Board of Directors to the effect that, as of the date
of such opinion and based upon the various qualifications and assumptions set
forth therein, the exchange ratio of the common shares of Dental Care Alliance
for common shares of Wisdom Holdings was fair, from a financial point of view,
to Gentle Dental.
    
 
   
    THE FULL TEXT OF SALOMON SMITH BARNEY INC.'S WRITTEN OPINION DATED OCTOBER
15, 1998 IS ATTACHED AS APPENDIX B TO THIS DOCUMENT AND IS INCORPORATED HEREIN
BY REFERENCE. GENTLE DENTAL SHAREHOLDERS ARE URGED TO READ THIS OPINION IN ITS
ENTIRETY FOR ASSUMPTIONS MADE, PROCEDURES FOLLOWED, MATTERS CONSIDERED AND
LIMITS OF THE REVIEW BY SALOMON SMITH BARNEY INC. IN ARRIVING AT ITS OPINION.
THE SUMMARY OF THE OPINION OF SALOMON SMITH BARNEY INC. SET FORTH IN THIS
DOCUMENT IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH
OPINION.
    
 
   
    Salomon Smith Barney Inc.'s opinion is directed only to the fairness, from a
financial point of view, to Gentle Dental of the exchange ratio of the common
shares of Dental Care Alliance for common shares of Wisdom Holdings and is not
intended and does not constitute a recommendation to any shareholder of Gentle
Dental as to how such shareholder should vote at the special meeting. No
limitations were imposed by the Gentle Dental Board of Directors upon Salomon
Smith Barney Inc. with respect to the investigations made or procedures followed
by it in rendering its opinion. Although Salomon Smith Barney Inc. evaluated the
financial terms of the mergers and participated in discussions concerning the
determination of the exchange ratio mentioned above, Salomon Smith Barney Inc.
was not asked to and did not recommend such exchange ratio, which was the result
of arm's length negotiations between Gentle Dental and Dental Care Alliance.
    
 
   
    In connection with rendering its opinion, Salomon Smith Barney Inc., among
other things:
    
 
   
    - reviewed the merger agreement;
    
 
   
    - held discussions with certain senior officers and other representatives
      and advisors of Gentle Dental and certain senior officers and other
      representatives and advisors of Dental Care Alliance concerning the
      business, operations and prospects of Gentle Dental and Dental Care
      Alliance;
    
 
   
    - examined certain publicly available business and financial information
      relating to Gentle Dental and Dental Care Alliance as well as certain
      financial forecasts and other data for Gentle Dental and Dental Care
      Alliance, which were provided by the respective managements of Gentle
      Dental and Dental Care Alliance, including information relating to certain
      strategic implications and operational benefits anticipated from the
      mergers;
    
 
                                       32
<PAGE>
   
    - reviewed the financial terms of the mergers as set forth in the merger
      agreement in relation to, among other things: current and historical
      market prices and trading volumes of the Gentle Dental common stock and
      the Dental Care Alliance common stock; the respective companies'
      historical and projected earnings and the capitalization and financial
      condition of Gentle Dental and Dental Care Alliance;
    
 
   
    - reviewed, to the extent publicly available, the financial terms of certain
      other similar recently effected transactions that Salomon Smith Barney
      Inc. considered comparable to the mergers and analyzed certain financial,
      stock market and other publicly available information relating to the
      businesses of other companies whose operations Salomon Smith Barney Inc.
      considered relevant in evaluating those of Gentle Dental and Dental Care
      Alliance; and
    
 
   
    - evaluated the potential pro forma financial impact of the mergers on
      Gentle Dental.
    
 
   
    In addition, Salomon Smith Barney Inc. conducted such other studies,
analyses, inquiries and investigations as it deemed appropriate.
    
 
   
    In rendering its opinion, Salomon Smith Barney Inc. assumed and relied,
without independent verification, upon the accuracy and completeness of all
financial and other information and data publicly available or furnished to or
otherwise reviewed by or discussed with it. With respect to financial forecasts
and other information and data provided to or otherwise reviewed by or discussed
with Salomon Smith Barney Inc., the managements of Gentle Dental and Dental Care
Alliance advised Salomon Smith Barney Inc. that such forecasts and other
information and data were reasonably prepared reflecting the best currently
available estimates and judgments of the respective managements of Gentle Dental
and Dental Care Alliance as to the future financial performance of Gentle Dental
and Dental Care Alliance and the strategic implications and operational benefits
anticipated to result from the mergers. Salomon Smith Barney Inc. assumed, with
the consent of the Gentle Dental Board of Directors, that the mergers will be
treated as a "pooling-of-interests" in accordance with generally accepted
accounting principles and as tax-free reorganizations for federal income tax
purposes.
    
 
   
    The opinion of Salomon Smith Barney Inc., as set forth therein, relates to
the relative values of Gentle Dental and Dental Care Alliance. Salomon Smith
Barney Inc. did not express any opinion as to what the value of the Wisdom
Holdings common stock actually will be when issued to Gentle Dental shareholders
pursuant to the mergers or the price at which the Wisdom Holdings common stock
will trade subsequent to the mergers. Salomon Smith Barney Inc. did not make,
and was not provided with, an independent evaluation or appraisal of the assets
or liabilities (contingent or otherwise) of Gentle Dental or Dental Care
Alliance nor did Salomon Smith Barney Inc. make any physical inspection of the
properties or assets of Gentle Dental or Dental Care Alliance. Salomon Smith
Barney Inc. was not requested to consider, and Salomon Smith Barney Inc.'s
opinion does not address, the relative merits of the mergers as compared to any
alternative business strategies that might exist for Gentle Dental or the effect
of any other transaction in which Gentle Dental might engage.
    
 
   
    In preparing its opinion, Salomon Smith Barney Inc. performed a variety of
financial and comparative analyses. The summary of such analyses set forth below
does not purport to be a complete description of the analyses performed and
factors considered by Salomon Smith Barney Inc. in arriving at its opinion. The
preparation of a fairness opinion is a complex process and is not necessarily
susceptible to partial analyses or summary description. Salomon Smith Barney
Inc. believes that its analyses must be considered as a whole, and that
selecting portions of its analyses or of the summary set forth below, without
considering the analyses as a whole, could create an incomplete view of the
processes underlying Salomon Smith Barney Inc.'s opinion. In arriving at its
fairness determination, Salomon Smith Barney Inc. considered the results of all
such reviews, calculations and analyses. The analyses were prepared solely for
the purpose of Salomon Smith Barney Inc. providing its opinion to the Gentle
Dental Board of Directors as to the fairness, from a financial point of view, to
Gentle Dental of the exchange ratio described above. The analyses performed by
Salomon Smith Barney Inc. are not necessarily indicative of actual values,
trading values or actual future results which might be achieved, all of which
may be significantly more or less favorable than suggested by such analyses. As
described above, certain of the analyses performed by
    
 
                                       33
<PAGE>
   
Salomon Smith Barney Inc. relied on forecasts of future financial performance
provided by the managements of Gentle Dental and Dental Care Alliance. Forecasts
of future financial performance are not necessarily indicative of actual future
results, which may be significantly more or less favorable than suggested by
such forecasts. Accordingly, because such forecasts are inherently subject to
substantial uncertainty, none of Gentle Dental, Dental Care Alliance, Salomon
Smith Barney Inc. or any other person assumes responsibility for the accuracy of
such forecasts.
    
 
    Salomon Smith Barney Inc.'s opinion was necessarily based on the information
made available to it, and financial, stock market and other conditions and
circumstances existing and disclosed to Salomon Smith Barney Inc. as of the date
of its opinion.
 
   
    The following is a summary of the material financial analyses performed by
Salomon Smith Barney Inc. in connection with the preparation of its opinion.
These analyses were presented to the Gentle Dental Board of Directors at its
meeting on October 14, 1998.
    
 
   
    COMPARABLE COMPANY ANALYSIS.  Salomon Smith Barney Inc. reviewed and
compared certain actual and estimated financial, operating and stock market
information of Dental Care Alliance with that of the following group of four
publicly traded companies in the dental practice management industry that
Salomon Smith Barney Inc. believed to be comparable in certain relevant respects
to Dental Care Alliance: Gentle Dental, American Dental Partners, Inc., Coast
Dental Services, Inc. and Monarch Dental Corp. Salomon Smith Barney Inc.
calculated certain financial multiples for Dental Care Alliance and each of the
selected companies, including, among others:
    
 
   
    - market value multiples as of October 10, 1998 based on estimated calendar
      years 1998 and 1999 earnings per share ("EPS");
    
 
   
    - enterprise value (market value, plus total debt, less cash) multiples as
      of October 10, 1998 based on last 12 months ("LTM") earnings before
      interest, taxes, depreciation and amortization;
    
 
   
    - enterprise value multiples as of October 10, 1998 based on last quarter
      annualized ("LQA") EBITDA; and
    
 
   
    - enterprise value multiples as of October 10, 1998 based on pro forma LQA
      EBITDA (giving effect to recent acquisitions).
    
 
   
    Salomon Smith Barney Inc. calculated the average of the foregoing multiples
and then calculated the high and low ranges of such multiples by multiplying
such average by 1.15 (to derive the high end) and .85 (to derive the low end).
EPS estimates for the selected companies mentioned above were obtained from
reports published by the First Call Corporation.
    
 
   
    The results of applying the foregoing high and low range of multiples for
the four publicly traded companies mentioned above to corresponding financial
data for Dental Care Alliance are summarized in the following table:

affect the public trading values of these companies.
    
 
   
    SELECTED GENTLE DENTAL MERGER AND ACQUISITION TRANSACTIONS ANALYSIS.  Using
publicly available information, Salomon Smith Barney Inc. analyzed the purchase
price and implied transaction value multiples paid in 12 selected transactions
involving the acquisition or proposed acquisition of all or part of certain
companies in the practice management industry since November 1996. The 12
transactions selected were:
    
 
   
    - the acquisition of Valley Forge Dental Associates. Inc. by Monarch Dental
      Corporation;
    
 
   
    - the acquisition of MedCath Incorporated by KKR 1996 Fund, L.P. and Welsh,
      Carson, Anderson & Stowe VII, L.P.;
    
 
   
    - the acquisition of First Physician Care, Inc. by PhyCor, Inc.;

      Inc.; and
    
 
   
    - the acquisition of STAT Healthcare, Inc. by American Medical Response,
      Inc.
    
 
   
    Salomon Smith Barney Inc. compared purchase prices in the foregoing selected
transactions as a multiple of, among other things, LTM net income, and
transaction values as multiples of, among other things, LTM earnings before
interest and taxes ("EBIT"), LTM EBITDA, LQA EBITDA and estimated forward years
EPS. All multiples for the foregoing selected transactions were based on
information available at the time of announcement of the selected transaction.
Salomon Smith Barney Inc. calculated the average of the foregoing multiples and
then calculated the high and low ranges of such multiples by multiplying such
average by 1.15 (to derive the high end) and .85 (to derive the low end). The
results of applying the foregoing high and low range of multiples for the
foregoing selected transactions to corresponding financial data for Dental Care
Alliance are summarized in the following table:

Care Alliance versus the acquisition values of the companies to which Dental
Care Alliance was being compared.
 
   
    DISCOUNTED CASH FLOW ANALYSIS.  Salomon Smith Barney Inc. calculated the
estimated free cash flows of Dental Care Alliance for the five fiscal years from
1999 through 2003, based on internal estimates of the management of Dental Care
Alliance. Salomon Smith Barney Inc. then calculated estimated terminal values
(as of December 31, 2003) by applying terminal value multiples of 6.5x, 7.5x and
8.5x to Dental Care Alliance's estimated fiscal year 2003 EBITDA. The sum of the
free cash flows for the covered period and the range of terminal values were
then discounted to present using discount rates of 15.0%, 17.5% and 20.0%. This
analysis was performed using estimated free cash flows and estimated fiscal year
2003 EBITDA under two scenarios, one assuming that the acquisitions contemplated
by Dental Care Alliance's forecasted business plans were consummated and the
other assuming that such acquisitions were not consummated.
    
 
   
    Assuming the above-described acquisitions were not consummated, this
analysis indicated the following results:
    
 
   
    - a present value of Dental Care Alliance's common equity (after subtracting
      net debt) of $9.17, $10.08 and $10.99 on the basis of terminal value
      EBITDA multiples of 6.5x, 7.5x and 8.5x, respectively, using a discount
      rate of 15.0%;
    
 
   
    - a present value of Dental Care Alliance's common equity (after subtracting
      net debt) of $8.43, $9.25 and $10.06 on the basis of terminal value EBITDA
      multiples of 6.5x, 7.5x and 8.5x, respectively, using a discount rate of
      17.5%; and
    
 
   
    - a present value of Dental Care Alliance's common equity (after subtracting
      net debt) of $7.77, $8.51 and $9.25 on the basis of terminal value EBITDA
      multiples of 6.5x, 7.5x and 8.5x, respectively, using a discount rate of
      20.0%.
    
 
   
    Assuming the above-described acquisitions were consummated, this analysis
indicated the following results:
    
 
   
    - a present value of Dental Care Alliance's common equity (after subtracting
      net debt) of $11.50, $12.73 and $13.97 on the basis of terminal value
      EBITDA multiples of 6.5x, 7.5x and 8.5x, respectively, using a discount
      rate of 15.0%;
    
   
    - a present value of Dental Care Alliance's common equity (after subtracting
      net debt) of $10.52, $11.63 and $12.74 on the basis of terminal value
      EBITDA multiples of 6.5x, 7.5x and 8.5x, respectively, using a discount
      rate of 17.5%; and
    
 
   
    - a present value of Dental Care Alliance's common equity (after subtracting
      net debt) of $9.66, $10.66 and $11.65 on the basis of terminal value
      EBITDA multiples of 6.5x, 7.5x and 8.5x, respectively, using a discount
      rate of 20.0%.
    
 
   
    CONTRIBUTION ANALYSIS.  Salomon Smith Barney Inc. analyzed the respective
contributions of Gentle Dental and Dental Care Alliance to, among other things,
the estimated revenues, EBIT, EBITDA and net income of the combined company for
calendar years 1998 and 1999, based on internal estimates of the managements of
Gentle Dental and Dental Care Alliance and assuming that the acquisitions
contemplated by each of Gentle Dental's and Dental Care Alliance's respective
business plans are consummated. This analysis indicated that:
    
 
   
    - in the estimated calendar year 1998, Gentle Dental would have contributed
      approximately 71.6% of revenues, 58.5% of EBITDA, 47.3% of EBIT and 33.8%
      of net income, and Dental Care Alliance would have contributed
      approximately 28.4% of revenues, 41.5% of EBITDA, 52.7% of EBIT and 66.2%
      of net income, of the combined company; and
    
 
                                       36
<PAGE>
    - in the estimated calendar year 1999, Gentle Dental would have contributed
      approximately 74.6% of revenues, 69.0% of EBITDA, 64.8% of EBIT and 50.8%
      of net income, and Dental Care Alliance would have contributed
      approximately 25.4% of revenues, 31.0% of EBITDA, 35.2% of EBIT and 49.2%
      of net income, of the combined company.
 
   
    Based on the exchange ratios applicable to the mergers, current stockholders
of Gentle Dental and Dental Care Alliance would own approximately 53.5% and
46.5%, respectively, of the equity of Wisdom Holdings upon consummation of the
mergers, on a fully diluted basis.
    
 
    OTHER ANALYSES.  Salomon Smith Barney Inc. conducted such other analyses as
it deemed necessary, including reviewing selected investment research reports
on, and earnings estimates for, Gentle Dental and Dental Care Alliance, and
analyzing available information regarding the stock ownership profile of Gentle
Dental and Dental Care Alliance.
 
   
    Salomon Smith Barney Inc. is an internationally recognized investment

    Pursuant to the terms of Salomon Smith Barney Inc.'s engagement, Gentle
Dental has agreed to pay Salomon Smith Barney Inc. for its services in
connection with the mergers an aggregate financial advisory fee based on a
percentage of the aggregate transaction value. The fee payable to Salomon Smith
Barney Inc. is currently estimated to be approximately $1.0 million,
approximately $260,000 of which is due and payable and the balance of which is
contingent upon completion of the mergers. Gentle Dental has also agreed to
reimburse Salomon Smith Barney Inc. for reasonable travel and other
out-of-pocket expenses incurred by Salomon Smith Barney Inc. in performing its
services, including the fees and expenses of its legal counsel, and to indemnify

arms' length relationships with Gentle Dental or Dental Care Alliance.
    
 
   
OPINION OF DENTAL CARE ALLIANCE'S FINANCIAL ADVISOR
    
 
   
    Pursuant to an engagement letter dated August 22, 1998, Dental Care Alliance
retained Raymond James & Associates, Inc. in connection with its consideration
of the mergers because of Raymond James & Associates, Inc.'s qualifications,
expertise and reputation, as well as its prior investment banking relationship
with Dental Care Alliance. In connection with such engagement, Dental Care
Alliance requested Raymond James & Associates, Inc. to render an opinion as to

ENTIRETY. RAYMOND JAMES & ASSOCIATES, INC.'S OPINION, WHICH IS ADDRESSED TO THE
DENTAL CARE ALLIANCE BOARD OF DIRECTORS, IS DIRECTED ONLY TO THE FAIRNESS OF THE
EXCHANGE RATIO APPLICABLE TO SHARES OF DENTAL CARE ALLIANCE COMMON STOCK TO
DENTAL CARE ALLIANCE STOCKHOLDERS FROM A FINANCIAL POINT OF VIEW AND DOES NOT
CONSTITUTE A RECOMMENDATION TO ANY DENTAL CARE ALLIANCE STOCKHOLDER AS TO HOW
SUCH STOCKHOLDER SHOULD VOTE AT THE DENTAL CARE ALLIANCE SPECIAL MEETING AND
DOES NOT ADDRESS ANY OTHER ASPECT OF THE PROPOSED MERGERS OR ANY RELATED
TRANSACTION. RAYMOND JAMES & ASSOCIATES, INC. HAS CONSENTED TO THE SUMMARIZATION
OF ITS OPINION IN, AND ATTACHMENT OF ITS OPINION TO, THIS DOCUMENT. THE SUMMARY
OF THE OPINION OF RAYMOND JAMES & ASSOCIATES, INC. SET FORTH IN THIS DOCUMENT IS
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION.
    
 
    The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to a partial analysis or summary description. Raymond
James & Associates, Inc. believes that its analyses must be considered as a
whole and that selecting portions of its analyses, without considering the
analyses taken as a whole, would create an incomplete view of the process
underlying the analyses set forth in its opinion. In addition, Raymond James &
Associates, Inc. considered the results of all such analyses and did not assign
relative weights to any of the analyses, so the ranges of valuations resulting
from any particular analysis described below should not be taken to be Raymond
James & Associates, Inc.'s view of the actual value of Dental Care Alliance or a
combination of Dental Care Alliance and Gentle Dental.
 
   
    In performing its analyses, Raymond James & Associates, Inc. made numerous
assumptions with respect to industry performance, general business, economic and
regulatory conditions and other matters, many of which are beyond the control of
Dental Care Alliance or Gentle Dental. The analyses performed by Raymond James &
Associates, Inc. are not necessarily indicative of actual values, trading values
or actual future results which might be achieved, all of which may be
significantly more or less favorable than suggested by such analyses. Such
analyses were prepared solely as part of Raymond James & Associates, Inc.'s
analysis of the fairness of the exchange ratio applicable to shares of Dental
Care Alliance to Dental Care Alliance stockholders from a financial point of
view and were provided to the Dental Care Alliance Board of Directors. The
analyses do not purport to be appraisals or to reflect the prices at which a
company might be sold. In addition, as described below, the opinion of Raymond
James & Associates, Inc. was one of many factors taken into consideration by the
Dental Care Alliance Board of Directors in making its determination to approve
the mergers. Consequently, the analyses described below should not be viewed as
determinative of the Dental Care Alliance Board of Directors' or Dental Care
Alliance management's opinion with respect to the value of Dental Care Alliance
or a combination of Dental Care Alliance and Gentle Dental, or of whether the
Dental Care Alliance Board of Directors or Dental Care Alliance management would
have been willing to agree to a different exchange ratio. Dental Care Alliance
placed no limits on the scope of the analysis performed, or opinion expressed,
by Raymond James & Associates, Inc.
    
 
    In connection with rendering its opinion, Raymond James & Associates, Inc.
has, among other things:
 
    - reviewed the annual report to stockholders on Form 10-K filed April 1,
      1998, the quarterly reports to stockholders on Forms 10-Q filed May 14,

      prospects of Dental Care Alliance and Gentle Dental with senior executives
      of Dental Care Alliance and Gentle Dental, respectively;

      to certain other companies in lines of business generally comparable to
      those of Dental Care Alliance and Gentle Dental;
 
   
    - considered the pro forma effects of the mergers on Dental Care Alliance's
      financial statements and reviewed certain estimates of synergies prepared
      by the managements of Dental Care Alliance and Gentle Dental;
    
 
   
    - reviewed the historical market prices of the Dental Care Alliance common
      stock and the Gentle Dental common stock;

    In connection with its review, Raymond James & Associates, Inc. has not
assumed any responsibility for independent verification for any of the
information reviewed by Raymond James & Associates, Inc. for the purpose of the
opinion and has relied on its being complete and accurate in all material
respects. In addition, Raymond James & Associates, Inc. has not made or received
any independent evaluation or appraisal of any of the assets or liabilities
(contingent or otherwise) of Dental Care Alliance and Gentle Dental, nor has
Raymond James & Associates, Inc. been furnished with any such evaluation or
appraisal. With respect to the financial forecasts, estimates, projections, pro
forma effects, calculations of synergies and other information referred to
below, Raymond James & Associates, Inc. has assumed, at the direction of Dental
Care Alliance and Gentle Dental, that they have been reasonably prepared on a
basis reflecting the best currently available estimates and judgments of the
management of Dental Care Alliance and Gentle Dental, and Raymond James &
Associates, Inc. has relied upon each party to advise Raymond James &
Associates, Inc. promptly if any such information previously provided to or

James & Associates, Inc. has assumed, with the consent of Dental Care Alliance
and Gentle Dental, that the mergers will be accounted for as a
"pooling-of-interests" under generally accepted accounting principles and that
the mergers will be considered tax-free reorganizations for tax purposes.
    
 
   
    PRESENTATION BY RAYMOND JAMES & ASSOCIATES, INC.  The following summarizes
the material financial analyses presented by Raymond James & Associates, Inc. to
the Dental Care Alliance Board of Directors at its meetings on October 13 and
15, 1998, which were considered by Raymond James & Associates, Inc. in rendering
the opinion described below. This summary is not a complete description of the
analyses underlying the opinion of Raymond James & Associates, Inc. or of
information presented at meetings between Raymond James & Associates, Inc. and
representatives of Dental Care Alliance held in advance of the consideration by
the Dental Care Alliance Board of Directors of the mergers.
    
 
   
    HISTORICAL STOCK PERFORMANCE ANALYSIS.  Raymond James & Associates, Inc.
described for the Dental Care Alliance Board of Directors the relative range of
implied exchange ratios which would have resulted from the application of
historical share prices for Dental Care Alliance common stock and Gentle Dental
common stock for the time period beginning November 4, 1997, when Dental Care
Alliance common stock began trading in the public market, and ending on October
12, 1998, the day prior to Raymond James & Associates, Inc.'s presentation to
the Dental Care Alliance Board of Directors. These implied Dental Care Alliance
exchange ratios were calculated by dividing the price per share for Dental Care
Alliance common
    
 
                                       39
<PAGE>
   
stock by the price per share for Gentle Dental common stock. During the time
period used for the analysis, the implied exchange ratio applicable to Dental
Care Alliance shares of common stock ranged from 0.83 to 1.81. This range of
implied Dental Care Alliance Exchange Ratios compares to the Dental Care
Alliance Exchange Ratio in the Agreement of 1.67.
    
 
   
    PRECEDENT TRANSACTION ANALYSIS.  Raymond James & Associates, Inc. also
presented to the Dental Care Alliance Board of Directors a summary of a
precedent transaction analysis which compared four key financial ratios for
seven selected precedent healthcare company combinations announced during the
three year period prior to October 13, 1998 to the same four key financial
ratios projected for the mergers. The precedent combinations consisted of:
    
 
    - Monarch Dental Corp. combining with Valley Forge Dental;
 
    - KKR Partners II, L.P. combining with Medcath, Inc.;
 
    - Laidlaw, Inc. combining with Emcare Holdings, Inc.;
 
    - Concentra combining with CRA Managed Care, Inc.;
 
    - MedPartners, Inc. combining with Inphynet Medical Management, Inc.;
 
    - Physicians Resource Group, Inc. combining with Equivision, Inc.; and
 
    - FPA Medical Management, Inc. combining with Sterling Healthcare Group,
      Inc.
 
    Raymond James & Associates, Inc. examined the following four key financial
ratios for these seven selected precedent healthcare company combinations:
 
    - target company enterprise value to target company net sales;
 
   
    - target company enterprise value to target company EBITDA;
    
 
   
    - target company enterprise value to target company EBIT; and
    
 
    - target company equity value to target company net income.
 
Net sales, EBITDA, EBIT and net income were calculated by annualizing the
financial statistics for the last quarter reported prior to the consummation of
the precedent company combinations.
   
    The precedent transaction analysis resulted in a target company enterprise
value to target company net sales ratio range of 0.8 to 2.2 for the seven
precedent combinations. This range compares to a projected enterprise value to
net sales ratio of 2.3 for Dental Care Alliance under the mergers. The precedent
transaction analysis resulted in a target company enterprise value to target
company EBITDA ratio range of 6.9 to 17.5 for the seven precedent combinations.
This range compares to a projected enterprise value to EBITDA ratio of 11.3 for
Dental Care Alliance under the merger of Dental Care Alliance contemplated by
the merger agreement. The precedent transaction analysis resulted in a target
company enterprise value to target company EBIT ratio range of 12.4 to 21.0 for
the seven precedent combinations. This range compares to a projected enterprise
value to EBIT ratio of 13.8 for Dental Care Alliance under the mergers. The
precedent transaction analysis resulted in a target company equity value to
target company net income ratio range of 20.9 to 39.7 for the seven precedent
combinations. This range compares to a projected equity value to company net
income ratio of 21.4 for Dental Care Alliance under the mergers. Net sales,
EBITDA, EBIT and net income for Dental Care Alliance were calculated by
annualizing Dental Care Alliance's reported financial statistics for its second
fiscal quarter of 1998.
    
 
   
    COMPARABLE COMPANIES ANALYSIS.  Raymond James & Associates, Inc. also
presented to the Dental Care Alliance Board of Directors a summary financial
comparison of Dental Care Alliance and Gentle Dental to 31 public practice
management companies, including multi-specialty physician practice management
companies, single specialty physician management companies, and dental and
orthodontic practice
    
 
                                       40
<PAGE>
management companies. For comparative purposes, Raymond James & Associates, Inc.
organized these companies into three groups:
 
    - public dental practice management companies,
 
   
    - public dental and orthodontic practice management companies,
    
 
    - all public practice management companies which include multi-specialty
      physician, single specialty physician, and dental and orthodontic practice
      management companies.
 
   
Raymond James & Associates, Inc. then compared the following four key financial
ratios for these three groupings of comparable companies to the same
corresponding ratios for Dental Care Alliance under the mergers:
    
 
    - enterprise value to sales;
 
    - enterprise value to EBITDA;
 
    - enterprise value to EBIT; and
 
    - equity value to net income.
 
Sales, EBITDA, EBIT and net income were calculated for Dental Care Alliance,
Gentle Dental and the comparable companies by annualizing the latest quarterly
financial statistics that have been publicly reported.
 
   
    The comparable companies analysis using the public dental practice
management company grouping resulted in an enterprise value to sales ratio range
of 0.4 to 1.9, an enterprise value to EBITDA ratio range of 2.6 to 9.4, an
enterprise value to EBIT ratio range of 3.1 to 14.1 and an equity value to net
income ratio range of 6.3 to 24.2. These ranges compare to a projected
enterprise value to sales ratio of 2.3 for Dental Care Alliance under the
mergers, a projected enterprise value to EBITDA ratio of 11.3 for Dental Care
Alliance under the mergers, a projected enterprise value to EBIT ratio of 13.8
for Dental Care Alliance under the mergers and a projected equity value to net
income ratio of 21.4 for Dental Care Alliance under the mergers.
    
 
   
    The comparable companies analysis using the public dental and orthodontic
practice management company grouping resulted in an enterprise value to sales
ratio range of 0.3 to 2.1, an enterprise value to EBITDA ratio range of 2.6 to
9.4, an enterprise value to EBIT ratio range of 3.1 to 14.1, and an equity value
to net income ratio range of 6.3 to 24.2. These ranges compare to a projected
enterprise value to sales ratio of 2.3 for Dental Care Alliance under the
mergers, a projected enterprise value to EBITDA ratio of 11.3 for Dental Care
Alliance under the mergers, a projected enterprise value to EBIT ratio of 13.8
for Dental Care Alliance under the mergers and a projected equity value to net
income ratio of 21.4 for Dental Care Alliance under the mergers.
    
 
   
    The comparable companies analysis for the all public practice management
company grouping resulted in an enterprise value to sales ratio range of 0.3 to
3.4, an enterprise value to EBITDA ratio range of 0.0 to 26.9, an enterprise
value to EBIT ratio range of 0.0 to 14.1, and an equity value to net income
ratio range of 2.9 to 24.2. These ranges compare to a projected enterprise value
to sales ratio of 2.3 for Dental Care Alliance under the proposed mergers, a
projected enterprise value to EBITDA ratio of 11.3 for Dental Care Alliance
under the proposed mergers, a projected enterprise value to EBIT ratio of 13.8
for Dental Care Alliance under the proposed mergers and a projected equity value
to net income ratio of 21.4 for Dental Care Alliance under the proposed mergers.

    DENTAL CARE ALLIANCE DISCOUNTED CASH FLOW ANALYSIS.  Raymond James &
Associates, Inc. presented to the Dental Care Alliance Board of Directors the
results of a discounted cash flow analysis for fiscal years 1999 to 2002 to
estimate the present value of the stand-alone unleveraged free cash flows that
Dental Care Alliance is expected to generate if Dental Care Alliance performs in
accordance with certain internal management forecasts. For purposes of this
analysis, unleveraged free cash flows were defined as unleveraged net income
plus depreciation plus amortization less capital expenditures less investment in
working capital. Raymond James & Associates, Inc. performed its analyses based
on financial forecasts and assumptions provided to it by Dental Care Alliance.
    
 
   
    Raymond James & Associates, Inc. used the year 2002 as the terminal year for
the analysis and calculated terminal values for Dental Care Alliance by applying
a range of multiples of EBITDA to the projected fiscal year 2002 EBITDA for
Dental Care Alliance. These multiples ranged from 4.0 to 8.1. The unleveraged
projected free cash flows and terminal values were then discounted using a range
of discount rates from 11.70% to 15.70%. Based on this analysis, the implied
equity values for Dental Care Alliance ranged from approximately $7.97 to $19.34
per share. This range of per share values compares to the projected price per
share to owners of Dental Care Alliance common stock of $10.12 under the
proposed mergers based on the exchange ratio applicable to shares of Dental Care
Alliance common stock of 1.67 in the merger agreement and the closing price of
Gentle Dental common stock of $5.625 per share on October 12, 1998.
    
 
   
    IMPLIED EQUITY VALUE RATIO ANALYSIS BASED ON DISCOUNTED CASH FLOWS FOR
DENTAL CARE ALLIANCE AND GENTLE DENTAL.  Raymond James & Associates, Inc.
presented to the Dental Care Alliance Board of Directors the summary of an
analysis comparing the ratios of the implied equity values for Dental Care
Alliance derived from the Dental Care Alliance discounted cash flow analysis
described above to the implied equity values for Gentle Dental derived from a
discounted cash flow analysis for Gentle Dental. Raymond James & Associates,
Inc. compared these implied equity value ratios to the projected implied equity
value ratio under the mergers. The implied equity value ratio analysis resulted
in a range of ratios of 42.1% / 57.9% to 52.1% / 47.9% for Dental Care Alliance
and Gentle Dental, respectively. This range of ratios compares to a projected
implied equity value ratio for each company under the mergers of 46.5% / 53.5%
for Dental Care Alliance and Gentle Dental, respectively, assuming conversion of
Gentle Dental's preferred stock and subordinate convertible debt into common
stock and treating all outstanding options, warrants and put rights for Dental
Care Alliance and Gentle Dental using the treasury stock method for the
calculation of common stock equivalents.
    
 
   
    PRO FORMA ACCRETION (DILUTION) ANALYSIS.  Using forecasts and assumptions
for the forecasts provided by Dental Care Alliance and Gentle Dental, Raymond
James & Associates, Inc. presented to the Dental Care Alliance Board of
Directors the summary of an analysis which compared estimated pro forma earnings
per share for the combined company for fiscal year 1999 to the earnings per
share of Dental Care Alliance on a stand alone basis. The analysis assumed
Dental Care Alliance acquired Gentle Dental and included estimated cost savings
from the synergies of the mergers which were estimated by Dental Care Alliance
and Gentle Dental and provided to Raymond James & Associates, Inc. Raymond James
& Associates, Inc. has relied upon this estimate in its analysis and has not
undertaken any independent verification of the cost savings amount. The pro
forma accretion dilution analysis showed that the mergers would lead to
projected fiscal year 1999 combined company pro forma earnings per share greater
than the Dental Care Alliance internally forecasted earnings per share on a
stand alone basis.
    
 
   
    SUMMARY OF RELATIVE FINANCIAL STATISTICS ANALYSIS.  Raymond James &
Associates, Inc. also presented to the Dental Care Alliance Board of Directors a
comparative summary of financial statistics for Dental Care Alliance and Gentle
Dental. This analysis examined annualized projected third quarter 1998 net
revenues, current estimated gross patient revenue run rate, annualized projected
third quarter 1998 EBITDA, current estimated EBITDA run rate, annualized third
quarter 1998 projected EBIT and
    
 
                                       42
<PAGE>
annualized third quarter projected net income. The projected and estimated
financial statistics were provided to Raymond James & Associates, Inc. by Dental
Care Alliance and Gentle Dental.
 
   
    The summary of relative financial statistics analysis provided the following
results. The annualized projected third quarter 1998 net revenues translates to
approximately 21.7% and 78.3% of the total pro forma combined net revenue for
Dental Care Alliance and Gentle Dental, respectively. The current estimated
gross patient revenue run-rate translates to approximately 27.7% and 72.3% of
total pro forma combined gross patient revenue run-rate for Dental Care Alliance
and Gentle Dental, respectively. The annualized projected third quarter 1998
EBITDA translates to approximately 38.8% and 61.2% of the total combined pro
forma annualized projected third quarter EBITDA for Dental Care Alliance and
Gentle Dental, respectively. The current estimated EBITDA run-rate translates to
approximately 36.6% and 63.4% of total pro forma combined EBITDA run-rate for
Dental Care Alliance and Gentle Dental, respectively. The projected annualized
EBIT for the third quarter of fiscal year 1998 translates to approximately 46.7%
and 53.3% of the total pro forma combined EBIT for Dental Care Alliance and
Gentle Dental, respectively. The projected annualized net income for the third
quarter of fiscal year 1998 translates to approximately 56.9% and 43.1% of the
total pro forma combined net income for Dental Care Alliance and Gentle Dental,
respectively. All of the above percentages compare to the ownership percentages
calculated using the Dental Care Alliance exchange ratio of 1.67 described in
the merger agreement of approximately 46.5% and approximately 53.5% for Dental
Care Alliance and Gentle Dental, respectively, assuming conversion of Gentle
Dental's preferred stock and convertible subordinate notes into common stock and
treating all outstanding options, warrants and put rights for Dental Care
Alliance and Gentle Dental using the treasury stock method for the calculation
of common stock equivalents.

EXCHANGE OF STOCK; TREATMENT OF OPTIONS AND OTHER RIGHTS TO ACQUIRE CAPITAL
  STOCK
    
 
   
    THE GENTLE DENTAL EXCHANGE.  At the effective time of the Gentle Dental
merger, each share of Gentle Dental common stock outstanding, other than such
shares in respect of which dissenters' rights, shall have been properly demanded
in accordance with Chapter 23B.13 of the Washington Business Corporation Act
will be exchangeable into one share of Wisdom Holdings common stock.
    
 
   
    Notwithstanding any other provision of the merger agreement, dissenting
shares will not be exchanged for shares of Wisdom Holdings common stock. Holders
of dissenting shares will be entitled to payment of the appraised value of such
dissenting shares in accordance with the provisions of Chapter 23B.13 of the
Washington Business Corporation Act, provided that if any dissenting shareholder
subsequently delivers a written withdrawal of such holder's demand for appraisal
of such shares, or if any holder fails to establish such holder's entitlement to
dissenters' rights as provided in Chapter 23B.13 of the Washington Business
Corporation Act, such holder or holders will forfeit the right to appraisal of
such shares of Gentle Dental common stock and each of such shares will thereupon
be deemed to have been exchanged for Wisdom
    
 
                                       44
<PAGE>
   
Holdings common stock on the terms provided in the merger agreement. See
"Dissenters' Appraisal Rights."
    
 
   
    Each stock option or other right to acquire Gentle Dental common stock
granted under Gentle Dental's option plans or other such rights that are
outstanding and unexercised immediately prior to the effective time of the
Gentle Dental merger will be converted automatically at the effective time into,
and will become, a stock option or other right to purchase Wisdom Holdings
common stock, and will continue, to the extent applicable, to be governed by the
terms of the Gentle Dental option plans or other applicable requirements. The
Gentle Dental option plans will be assumed by Wisdom Holdings. In each case, the
number of shares of Wisdom Holdings common stock subject to the option or other
right will be equal to the number of shares of Gentle Dental common stock
subject to the Gentle Dental option or right and the exercise price per share of
Wisdom Holdings common stock subject to the Wisdom Holdings option or right will
be equal to the exercise price per share of Gentle Dental common stock under the
Gentle Dental option or right. The duration and other terms of each such Wisdom
Holdings option or right will be substantially the same as the prior Gentle
Dental option or right.
    
 
   
    If, prior to the effective time of the Gentle Dental merger, the outstanding
shares of Gentle Dental capital stock are increased, decreased, changed into or
exchanged for a different number or kind of shares or securities as a result of
a reorganization, recapitalization, reclassification, stock dividend, stock
split, reverse stock split or other similar change in capitalization, an
appropriate and proportionate adjustment will be made to the exchange ratio of
shares of Gentle Dental capital stock for shares of Wisdom Holdings capital
stock.
    
 
   
    Each share of Gentle Dental Series A preferred stock issued and outstanding
prior to the effective time of the Gentle Dental merger shall be converted into
and exchanged for one share of Wisdom Holdings Series A preferred stock. The
terms of the Wisdom Holdings Series A preferred stock will be substantially the
same as the terms of the Gentle Dental Series A preferred stock. Each share of
Gentle Dental Series B preferred stock issued and outstanding prior to the
effective time of the Gentle Dental merger shall be converted into and exchanged
for one share of Wisdom Holdings Series B preferred stock. The terms of the
Wisdom Holdings Series B preferred stock will be substantially the same as the
terms of the Gentle Dental Series B preferred stock. Each share of Gentle Dental
Series C preferred stock issued and outstanding prior to the effective time
shall be converted into and exchanged for one share of Wisdom Holdings Series C
preferred stock. The terms of the Wisdom Holdings Series C preferred stock will
be substantially the same as the terms of the Gentle Dental Series C preferred
stock. Each share of Gentle Dental Series D preferred stock issued and
outstanding prior to the effective time of the Gentle Dental merger shall be
converted into and exchanged for one share of Wisdom Holdings Series D preferred
stock. The terms of the Wisdom Holdings Series D preferred stock will be
substantially the same as the terms of the Gentle Dental Series D preferred
stock. See Description of "Wisdom Holdings Capital Stock and Certain Differences
Between Washington and Delaware Laws." See "--Exchange of Certificates;
Fractional Shares."
    
 
   
    THE DENTAL CARE ALLIANCE EXCHANGE.  At the effective time of the Dental Care
Alliance merger, each share of Dental Care Alliance common stock outstanding
will be converted into and exchanged for the right to receive a number of shares
of Wisdom Holdings common stock equal to the exchange ratio (1.67) applicable to
such shares, subject to customary antidilution adjustments as provided in the
merger agreement and described below. Because the exchange ratio is fixed and
because the market price of Dental Care Alliance common stock (prior to the
effective time of the Dental Care Alliance merger) is subject to fluctuation,
the value of the shares of Wisdom Holdings common stock that holders of Dental
Care Alliance common stock will receive in the Dental Care Alliance merger may
increase or decrease prior to and following the Dental Care Alliance merger.

granted under Dental Care Alliance's option plans, or otherwise, outstanding and

time of the Dental Care Alliance merger, will be converted automatically at the
effective time into, and will become, a stock option or warrant to purchase
Wisdom Holdings common stock and will continue to be governed by the terms of
the applicable Dental Care Alliance option plan. The Dental Care Alliance option
plans will be assumed by Wisdom Holdings. In each case, (a) the number of shares
of Wisdom Holdings common stock subject to the Wisdom Holdings option or warrant
will be equal to the product of the number of shares of Dental Care Alliance
common stock multiplied by the Dental Care Alliance exchange ratio, rounded to
the nearest whole share, and (b) the exercise price per share of Wisdom Holdings
common stock subject to the Wisdom Holdings option or warrant will be equal to
the exercise price per share divided by the Dental Care Alliance exchange ratio
applicable to shares of Dental Care Alliance common stock, rounded to the
nearest whole cent. The duration and other terms of each such Wisdom Holdings
option or warrant will be substantially the same as the prior Dental Care
Alliance option, except that pursuant to the Dental Care Alliance option plans,
the exercisability of all options under such plans accelerate.
    
 
   
    If, prior to the effective time of the Dental Care Alliance merger, the
outstanding shares of Dental Care Alliance common stock are increased,
decreased, changed into or exchanged for a different number or kind of shares or
securities as a result of a reorganization, recapitalization, reclassification,
stock dividend, stock split, reverse stock split, or other similar change in
capitalization, an appropriate and proportionate adjustment will be made to the
exchange ratio applicable to shares of Dental Care Alliance common stock.
    
 
EXCHANGE OF CERTIFICATES; FRACTIONAL SHARES
 
   
    At or prior to the effective time of the mergers, Wisdom Holdings will
deposit, or cause to be deposited, with               , or another bank or trust

which shall act as exchange agent for the Gentle Dental merger, for the benefit
of the holders of certificates of Gentle Dental common stock, certificates
representing the shares of Wisdom Holdings capital stock to be issued pursuant
to the merger agreement in exchange for outstanding shares of Gentle Dental
capital stock.
    
 
   
    As soon as is practicable after the effective time of the Gentle Dental

holders of Gentle Dental capital stock. The form of transmittal letter will
contain instructions with respect to the surrender of certificates representing
Gentle Dental capital stock.

shall act as exchange agent for the Dental Care Alliance merger, for the benefit
of the holders of certificates of Dental Care Alliance common stock,
certificates representing the shares of Wisdom Holdings common stock and cash in
lieu of any fractional shares to be issued and delivered pursuant to the merger
agreement in exchange for outstanding shares of Dental Care Alliance common
stock.
    
 
   
    As soon as is practicable after the effective time of the Dental Care
Alliance merger, a form of transmittal letter will be mailed by the exchange
agent to the holders of Dental Care Alliance common stock. The form of
transmittal letter will contain instructions with respect to the surrender of
certificates representing Dental Care Alliance common stock.

AGENT UNLESS AND UNTIL THE GENTLE DENTAL SHAREHOLDER OR THE DENTAL CARE ALLIANCE
STOCKHOLDER RECEIVES A FORM OF TRANSMITTAL LETTER FOLLOWING THE EFFECTIVE TIME
OF THE APPLICABLE MERGER.
    
 
   
    Until the certificates representing Gentle Dental capital stock and Dental
Care Alliance common stock, as the case may be, are surrendered for exchange

                                       46
<PAGE>
   
dividends or other distributions declared after the effective time, if any, will
accrue but not be paid with respect to Wisdom Holdings common stock or Wisdom
Holdings preferred stock, as the case may be, for which their shares have been
exchanged. When such certificates are surrendered, any unpaid dividends or other
distributions will be paid, without interest. After the effective time of the
applicable merger, there will be no transfers on the stock transfer books of
Gentle Dental of shares of Gentle Dental capital stock or of Dental Care
Alliance of shares of Dental Care Alliance common stock issued and outstanding
immediately prior to the effective time of the applicable merger. If
certificates representing shares of Gentle Dental capital stock or Dental Care
Alliance common stock are presented after the effective time, they will be
canceled and exchanged for the relevant certificate representing the applicable
shares of Wisdom Holdings common stock or Wisdom Holdings preferred stock.
    
 
   
    No fractional shares of Wisdom Holdings common stock will be issued to any
holder of Dental Care Alliance common stock upon consummation of the Dental Care
Alliance merger. For each fractional share that would otherwise be issued,
Wisdom Holdings will pay cash in an amount equal to such fraction multiplied by
the average of the closing sale prices of Gentle Dental common stock as reported
on the Nasdaq Small Cap Market for the five consecutive trading days immediately
preceding the date of the effective time of the Gentle Dental merger. No
interest will be paid or accrued on the cash in lieu of fractional shares
payable to holders of such certificates.
    
 
   
    Neither Gentle Dental, Dental Care Alliance, Wisdom Holdings, nor any other
person, will be liable to any former holder of Gentle Dental capital stock or
Dental Care Alliance common stock for any amount properly delivered to a public
official pursuant to applicable abandoned property, escheat or similar laws.
    
 
   
    If a certificate for Gentle Dental capital stock or Dental Care Alliance
common stock has been lost, stolen or destroyed, the exchange agent will issue
the consideration properly payable in accordance with the merger agreement upon
receipt of appropriate evidence as to such loss, theft or destruction,
appropriate evidence as to the ownership of such certificate by the claimant,
and appropriate and customary indemnification.

EFFECTIVE TIME
 
   
    The effective time of the mergers will be as set forth in the certificate of
merger that will be filed with the Secretary of State of the State of Washington
and the certificate of merger that will be filed with the Secretary of State of
the State of Delaware on the closing date of the mergers. The closing date will
occur on a date to be specified by the parties, but no later than five business
days after the satisfaction or waiver (subject to applicable law) of the latest
to occur of the conditions precedent to the mergers set forth in Article IX of
the merger agreement. Gentle Dental and Dental Care Alliance each anticipate
that the mergers will be consummated during the fiscal quarter ending March 31,
1999. However, the consummation of the mergers could be delayed if there is a
delay in obtaining requisite regulatory approvals. There can be no assurances as
to if or when such approvals will be obtained or that the mergers will be
consummated. If the mergers are not effected on or before March 31, 1999, the
merger agreement may be terminated by either Gentle Dental or Dental Care
Alliance, unless the failure to effect the mergers by such date is due to the
failure of the party seeking to terminate the merger agreement to perform or
observe the covenants and agreements of such party set forth therein. See
"--Conditions to Consummation of the Mergers" and "--Regulatory Approvals
Required for the Mergers."

or waived by the party permitted to do so. If the mergers are not effected on or
before March 31, 1999, the merger agreement may be terminated by either Gentle
Dental or Dental Care Alliance, unless the failure to effect the mergers by such
date is due to the failure of the party seeking to terminate the merger
agreement to perform or observe covenants and agreements of such party set forth
therein.

REGULATORY APPROVALS REQUIRED FOR THE MERGERS
 
   
    Gentle Dental and Dental Care Alliance have agreed to use their best efforts
to obtain all regulatory approvals required to consummate the transactions
contemplated by the merger agreement and intend to complete the filing of
applications and notifications to obtain such approvals of any governmental
authority promptly after the date of this document or have completed the filing
of such applications and notifications prior to such date. The mergers cannot
proceed in the absence of the approvals of any government authority. There can
be no assurance as to the date of any such approvals or the absence of any
litigation challenging such approvals. There can likewise be no assurance that
the Federal Trade Commission, United States Department of Justice or any state
attorney general will not attempt to challenge the mergers on antitrust grounds,
or, if such a challenge is made, as to the result thereof.
    
 
   
    Gentle Dental and Dental Care Alliance are not aware of any other material
governmental approvals or actions that are required prior to the parties'
consummation of the mergers other than those described below. It is presently
contemplated that if any such additional governmental approvals or actions are
required, such approvals or actions will be sought. There can be no assurance,
however, that any such additional approvals or actions will be obtained.
    
 
   
    Certain other approvals, notices or consents may be required from certain
regulatory authorities in connection with the changes, as a result of the
mergers, including the Nasdaq National Market, the Nasdaq SmallCap Market,
certain other securities exchanges, the National Association of Securities
Dealers, Inc. and certain other self-regulatory agencies.
    
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
   
    The following is a summary of the material United States federal income tax
consequences of the mergers to Gentle Dental shareholders and Dental Care
Alliance stockholders. The summary is based on the Internal Revenue Code of
1986, as amended, Treasury regulations thereunder, and administrative rulings
and court decisions in effect as of the date hereof, all of which are subject to
change at any time, possibly with retroactive effect. This summary is not a
complete description of all of the consequences of the mergers and, in
particular, may not address United States federal income considerations
applicable to stockholders subject to special treatment under United States
federal income tax law. In addition, no information is provided herein with
respect to the tax consequences of the mergers under applicable foreign, state
or local laws.
    
 
   
    GENTLE DENTAL SHAREHOLDERS AND DENTAL CARE ALLIANCE STOCKHOLDERS ARE URGED
TO CONSULT THEIR TAX ADVISORS REGARDING THE TAX CONSEQUENCES OF THE MERGERS TO
THEM.
    
 
   
    GENERAL.  In connection with the filing of the Registration Statement, of
which this document is a part, each of Gentle Dental and Dental Care Alliance
will receive an opinion of McDermott, Will & Emery, counsel to Gentle Dental and
Dental Care Alliance, dated the date thereof, addressing the United States
federal income tax consequences of the mergers described below. Such opinions
will be rendered on the basis of facts, representations and assumptions set
forth or referred to in such opinions that are consistent with the expected
state of facts existing at the effective time of the mergers. In rendering those
opinions, McDermott, Will & Emery will require and rely upon factual
representations contained in certificates of officers of Wisdom Holdings, Gentle
Dental and Dental Care Alliance and may rely on representations of others. The
opinions are to the effect that, for United States federal income tax purposes:
    
 
   
       - Each of the Gentle Dental merger and the Dental Care Alliance merger
         constitutes (A) a reorganization within the meaning of Section 368(a)
         of the Code and Wisdom Holdings, Gentle Dental, Wisdom Holdings
         Acquisition Corp. I, Dental Care Alliance and Wisdom Holdings
         Acquisition Corp. II will each be a party to the reorganization within
         the meaning of
    
 
                                       53
<PAGE>
   
         Section 368(b) of the Code or (B) transfers to a controlled corporation
         qualifying under Section 351 of the Code, and
    
 
   
       - No gain or loss will be recognized by shareholders of Gentle Dental who
         receive shares of Wisdom Holdings common stock or Wisdom Holdings
         Series D preferred stock in exchange for shares of Gentle Dental common
         stock or Gentle Dental Series D preferred stock or by stockholders of
         Dental Care Alliance who receive shares of Wisdom Holdings common stock
         in exchange for shares of Dental Care Alliance common stock, except
         with respect to cash received in lieu of fractional share interests of
         Wisdom Holdings.
    
 
   
    Neither tax opinion to be delivered in connection with the mergers is
binding on the Internal Revenue Service or the courts, and the parties do not
intend to request a ruling from the Internal Revenue Service with respect to the
mergers. Accordingly, there can be no assurance that the Internal Revenue
Service will not challenge the conclusions reflected in such opinions or that a
court will not sustain such challenge.
    
 
   
    The receipt of a cash payment in respect of dissenting shares by a
dissenting Gentle Dental shareholder will be a taxable event for United States
federal income tax purposes, and any such shareholder should consult his or her
tax advisor with respect to the tax consequences of such a cash payment in his
or her individual situation. Based upon the current ruling position of the
Internal Revenue Service, cash received by a Dental Care Alliance stockholder in
lieu of a fractional share interest in Wisdom Holdings common stock will be
treated as received in redemption of such fractional share interest, and a
Dental Care Alliance stockholder should generally recognize capital gain or loss
for United States federal income tax purposes measured by the difference between
the amount of cash received and the portion of the tax basis of the
stockholder's Dental Care Alliance common stock allocable to such fractional
share interest. Such gain or loss will be a long-term capital gain or loss if
the holding period for such share of Dental Care Alliance common stock is
greater than one year at the effective time of the Dental Care Alliance merger.
    
 
   
    The adjusted tax basis of the Wisdom Holdings common stock or Series D
preferred stock received by a Gentle Dental or Dental Care Alliance stockholder
pursuant to the mergers will be the same as that stockholder's adjusted tax
basis in the Gentle Dental common stock, Gentle Dental Series D preferred stock
or Dental Care Alliance common stock, as the case may be, surrendered in
exchange therefor. The holding period of Wisdom Holdings common stock or Wisdom
Holdings Series D preferred stock received by a Gentle Dental or Dental Care
Alliance stockholder (including a fractional share interest deemed received and
redeemed as described above) will include the holding period of the Gentle
Dental common stock, Gentle Dental Series D preferred stock or Dental Care
Alliance common stock surrendered in exchange therefor, provided that the
surrendered stock was held as a capital asset at the effective time of the
mergers. If a Gentle Dental or Dental Care Alliance stockholder has differing
bases or holding periods in respect of his Gentle Dental or Dental Care Alliance
stock, he should consult his own tax advisor prior to the mergers with regard to
identifying the bases or holding periods of particular shares of Wisdom Holdings
common stock or Wisdom Holdings Series D preferred stock received in the
mergers. None of Wisdom Holdings, Gentle Dental and Dental Care Alliance will
recognize any gain or loss as a result of the mergers.
    
 
   
    BACKUP WITHHOLDING AND INFORMATION REPORTING.  Under the backup withholding
rules, a holder of Wisdom Holdings common stock or Wisdom Holdings Series D
preferred stock may be subject to backup withholding at a rate of 31% with
respect to dividends, unless the stockholder (a) is a corporation or comes
within certain other exempt categories and, when required, demonstrates that
fact or (b) provides a correct taxpayer identification number and certifies as
to no loss of exemption from backup withholding on the substitute Form W-9 that
will be included as part of the transmittal letter and otherwise complies with
the applicable requirements of the backup withholdings rules. Any amount
withheld under those rules will be credited against the stockholder's federal
income tax liability or refunded, provided the appropriate information is
furnished to the Internal Revenue Service. A Wisdom Holdings stockholder who
does not
    
 
                                       54
<PAGE>
   
provide Wisdom Holdings with his or her correct taxpayer identification number
or who otherwise does not establish an exemption, in addition to being subject
to backup withholding at the rate of 31% with respect to dividends, may be
subject to penalties imposed by the Internal Revenue Service. The information
reporting rules will apply to dividends on Wisdom Holdings common stock and
Wisdom Holdings Series D preferred stock unless the stockholder is a corporation
or is otherwise exempt from those rules.
    
 
   
    It is a condition to consummation of the mergers that Gentle Dental and
Dental Care Alliance receive the above-described tax opinion from McDermott,
Will & Emery. We can waive these conditions. In the event that either of these
conditions is waived, the companies will amend this document and resolicit their
stockholders. See "--Conditions to Consummation of the Mergers."
    
 
ACCOUNTING TREATMENT
 
   
    The parties anticipate that the mergers will be accounted for as
"pooling-of-interests" transactions under Generally Accepted Accounting
Principles. Under such method of accounting, Gentle Dental shareholders and
Dental Care Alliance stockholders will be deemed to have combined their existing
voting common stock interests by virtue of the exchange of shares of Gentle
Dental capital stock into (in the case of Gentle Dental shareholders), or the
exchange of the shares of Dental Care Alliance common stock (in the case of
Dental Care Alliance stockholders), for shares of Wisdom Holdings common stock.
Accordingly, the book value of the assets, liabilities and stockholders' equity
of each of Gentle Dental and Dental Care Alliance, as reported on its respective
consolidated balance sheet, will be carried over to the consolidated balance
sheet of Wisdom Holdings and no goodwill will be created. Wisdom Holdings will
be able to include in its consolidated income the consolidated income of both
companies for the entire fiscal year in which the mergers occur; however,
certain expenses incurred to effect the mergers must be treated as current
charges against income rather than adjustments to the balance sheet.
    
 
   
    It is a condition to consummation of the mergers that Gentle Dental and
Dental Care Alliance receive a letter from their respective independent
accountants to the effect that the combining companies qualify, as of the
closing date of the mergers, for use of the pooling-of-interests method of
accounting for the mergers. We can waive this condition. In the event either of
these conditions is waived, the companies will amend this document and resolicit
their stockholders. See "--Conditions to Consummation of the Mergers."
    
 
   
    The unaudited pro forma financial information contained in this document has
been prepared assuming that the transaction will qualify as a
"pooling-of-interests." See "Summary--Selected Unaudited Comparative Per Share
Data" and "Unaudited Pro Forma Condensed Combined Financial Information."
    
 
TERMINATION OF THE MERGER AGREEMENT
 
   
    The merger agreement provides that the mergers may be terminated at any time
prior to the effective time, whether before or after approval by holders of
Gentle Dental common stock and Dental Care Alliance common stock:
    
 
   
    - by mutual consent of Gentle Dental and Dental Care Alliance, if the Board
      of Directors of each so determines by a vote of a majority of the members
      of its entire Board of Directors;
    
 
   
    - by either the Gentle Dental Board of Directors or Dental Care Alliance
      Board of Directors (provided that the terminating party is not then in
      material breach of any representation, warranty, covenant or other
      agreement contained in the merger agreement) if there has been a breach by
      the other party of any of the covenants or agreements or any of the
      representations or warranties set forth in the merger agreement, which
      breach is not cured within 30 days following written notice to the party
      committing such breach provided that such breach would be reasonably
      likely to result in a material adverse effect;
    
 
                                       55
<PAGE>
   
    - by either the Gentle Dental Board of Directors or Dental Care Alliance
      Board of Directors if the mergers are not consummated on or before March
      31, 1999, except by a party to the extent that the failure to be
      consummated arises out of or results from the knowing action or inaction
      of such party to the detriment of the other;
    
 
   
    - by either the Gentle Dental Board of Directors or Dental Care Alliance
      Board of Directors by a vote of a majority of the members of its entire
      Board of Directors if any governmental authority has denied approval of
      the mergers and such denial has become final and non-appealable or any
      governmental authority has issued a final non-appealable order enjoining
      or otherwise prohibiting the consummation of the transactions contemplated
      by the merger agreement;
    
 
   
    - by either Gentle Dental or Dental Care Alliance if any approval of the
      stockholders of Gentle Dental or Dental Care Alliance required for
      consummation of the mergers shall have not been obtained by reason of the
      failure to obtain the required vote at a duly held meeting of stockholders
      or any adjournment or postponement thereof; or
    
 
   
    - by written notice of Gentle Dental or Dental Care Alliance if either
      receives an acquisition proposal that meets certain parameters described
      more fully in the merger agreement and outside counsel advises that to
      proceed with the mergers would violate either the fiduciary duty of the
      Board of Directors of either company to its respective stockholders, and
      Gentle Dental or Dental Care Alliance decides to accept the acquisition
      proposal; provided, however, that notice is received by the
      non-terminating party at least two days prior to the determination to
      accept such proposal.
    
 
   
    In addition, in the event the mergers are not completed because the merger
agreement is terminated under its terms for a breach, the breaching party shall
be liable to the non-breaching party for an amount up to the actual
out-of-pocket costs and expenses of the non-breaching party. If, however, either
the Gentle Dental Board or the Dental Care Alliance Board of Directors fails to
recommend the mergers due to any reason other than a termination as permitted
above or either Gentle Dental or Dental Care Alliance accepts an acquisition
proposal from a third party, the party that fails to recommend under such
circumstances or the party that accepts a third party acquisition proposal shall
pay the other party a termination fee equal to $1.5 million.
    
 
   
    Whether or not the mergers are consummated, all fees and expenses incurred
in connection with the mergers and the transactions contemplated thereby will be
paid by the party incurring such expenses.
    
 
   
WAIVER AND AMENDMENT OF THE MERGER AGREEMENT
    
 
   
    At any time prior to the effective time, any provision of the merger
agreement may be (a) waived by the party benefited by the provision or (b)
amended or modified by an agreement in writing between the parties to the merger
agreement, except, following the meetings of the respective stockholders of
Gentle Dental and Dental Care Alliance, the merger agreement may not be amended
if such amendment would violate either the Washington Business Corporation Act
or the Delaware General Corporation Law or reduce the consideration to be
received by the stockholders of Gentle Dental or Dental Care Alliance.
    
 
EMPLOYEE BENEFITS AND PLANS
 
   
    Wisdom Holdings will:
    
 
   
    - provide former employees of both Gentle Dental and Dental Care Alliance
      who remain as employees of Wisdom Holdings or any of its subsidiaries with
      employee benefit plans no less favorable in the aggregate than those
      provided to similarly situated employees of Wisdom Holdings or its
      subsidiaries, including, but not limited to, allowing such employees to
      participate in Wisdom Holdings' stock option plan or plans in accordance
      with the policies of Wisdom Holdings with respect to such stock option
      plan or plans, and
    
 
                                       56
<PAGE>
   
    - with respect to former employees of Gentle Dental or Dental Care Alliance
      who remain as employees of Wisdom Holdings or any of its subsidiaries,
      cause each employee benefit plan of Wisdom Holdings or its subsidiaries in
      which such employees are eligible to participate to take into account for
      purposes of eligibility and vesting thereunder the service of such
      employees with Gentle Dental or Dental Care Alliance (as applicable) as if
      such service were with Wisdom Holdings or its subsidiaries, to the same
      extent such service was credited under a comparable plan of Gentle Dental
      or Dental Care Alliance (as applicable).
    
 
   
Wisdom Holdings has agreed to pay all accrued bonuses for 1998 to former
employees of Gentle Dental or Dental Care Alliance (as applicable) in accordance
with Gentle Dental's or Dental Care Alliance's past practices. After the
effective time, Gentle Dental's and Dental Care Alliance's benefit plans (as
applicable) will be governed, managed and/or terminated by Wisdom Holdings, all
within Wisdom Holdings' sole discretion.
    
 
   
    Following the effective time, Wisdom Holdings will deliver to the
participants in the option plans of Gentle Dental and Dental Care Alliance a
notice setting forth such participant's rights pursuant thereto. The grants
pursuant to these option plans shall continue in effect on the same terms and
conditions (after giving effect to the mergers), and Wisdom Holdings has agreed
to comply with the terms of each of these plans to ensure that stock options
granted under such plans that qualified as incentive stock options prior to the
effective time continue to qualify as incentive stock options.
    
 
   
    Wisdom Holdings has also agreed to take all corporate action necessary to
reserve for issuance a sufficient number of shares of Wisdom Holdings common
stock for delivery under each Gentle Dental option plan and Dental Care Alliance
option plan assumed in accordance with the merger agreement. As soon as
practicable after the effective time, Wisdom Holdings will file a registration
statement covering such shares and shall use its best efforts to maintain the
effectiveness of such registration statement or registration statements (and
maintain the current status of the prospectus or prospectuses contained therein)
for so long as such options remain outstanding.
    
 
STOCK EXCHANGE LISTING
 
   
    Wisdom Holdings has agreed to cause the shares of Wisdom Holdings common
stock to be issued in the mergers to be approved for listing on the Nasdaq
National Market. It is a condition to the consummation of the mergers that such
shares of Wisdom Holdings common stock be authorized for listing on Nasdaq,
subject to official notice of issuance.
    
 
EXPENSES
 
   
    The merger agreement provides that each of Gentle Dental and Dental Care
Alliance will pay its own expenses in connection with the mergers and the
transactions contemplated thereby.
    
 
   
INTERESTS OF CERTAIN PERSONS IN THE MERGERS
    
 
   
    Due to the benefits received by certain affiliates of Gentle Dental and
Dental Care Alliance in connection with the mergers, as described below, the
interests of these affiliates may be different from the interests of the
stockholders of Gentle Dental and Dental Care Alliance generally. Stockholders
should consider such affiliates' interests in the mergers in connection with
such affiliates' recommendations of the mergers.
    
 
   
    SEVERANCE ARRANGEMENTS.  In anticipation of the consummation of the mergers,
certain executive officers of Gentle Dental and Dental Care Alliance will
execute employment agreements with Wisdom Holdings, each of which becomes
effective at the effective time of the mergers. Each employment agreement with
Wisdom Holdings shall be assumed by Wisdom Holdings and expressly supersedes any
employment agreement between such person and Gentle Dental or Dental Care
Alliance, as the case may
    
 
                                       57
<PAGE>
   
be. In addition, each Gentle Dental or Dental Care Alliance executive officer
will have waived his rights to payments or other benefits which would otherwise
vest at the effective time under any agreement with Gentle Dental or Dental Care
Alliance. The terms and conditions, including severance arrangements, of
employment agreements with Wisdom Holdings for Messrs. Van Eerden, Olan and
Nichols will remain substantially similar to the previous employment agreements
with Gentle Dental and Dental Care Alliance, as the case may be. The employment
agreements with Wisdom Holdings for Mr. Fiore and Dr. Matzkin will have certain
modifications from the previous employment agreement with Gentle Dental and
Dental Care Alliance, respectively. See "Information About Gentle
Dental--Certain Transactions Regarding Gentle Dental" for a summary of the terms
of Mr. Fiore's employment agreement and new agreement with Wisdom Holdings. See
"Information About Dental Care Alliance--Employment Agreements" for a summary of
the terms of Dr. Matzkin's employment agreement and new agreement with Wisdom
Holdings.
    
 
   
    STOCK-BASED RIGHTS.  The merger agreement provides that, at the effective
time, each outstanding stock option to acquire shares of Gentle Dental common
stock granted under the Gentle Dental option plans or Dental Care Alliance
common stock under Dental Care Alliance option plans, each warrant and other
right to acquire Gentle Dental common stock or Dental Care Alliance common
stock, held by certain executive officers and directors, will cease to represent
the right to acquire shares of Gentle Dental common stock or Dental Care
Alliance common stock and will be converted into and become a right with respect
to shares of Wisdom Holdings common stock. Any such option plans existing at the
effective time will be assumed by Wisdom Holdings.
    
 
   
    REGISTRATION RIGHTS.  All of the affiliates of Wisdom Holdings will receive
registration rights as to all shares of Wisdom Holdings common stock held by
them following the effective time and all shares underlying any options,
warrants, convertible securities and other rights to purchase or acquire shares
of Wisdom Holdings common stock.
    
 
   
    STOCKHOLDERS' AGREEMENT.  As of September 30, 1998, directors and executive
officers of Gentle Dental and their affiliates may be deemed to be beneficial
owners of approximately 56.58% of the outstanding shares of Gentle Dental
capital stock. Holders of more than 50% of the Gentle Dental capital stock,
including shares held by certain executive officers and directors, have executed
Stockholders' Agreements whereby they agree to vote or direct the vote of all
such outstanding shares of Gentle Dental capital stock over which they have
voting control in favor of the approval and adoption of the merger agreements
and the transactions contemplated thereby. As of September 30, 1998, directors
and executive officers of Dental Care Alliance and their affiliates may be
deemed to be beneficial owners of approximately 31.3% of the outstanding shares
of Dental Care Alliance common stock. Any holder of more than 50% of the Dental
Care Alliance common stock, including shares held by certain executive officers
and directors, will execute Stockholders' Agreements whereby each will vote or
direct the vote of all such outstanding shares of Dental Care Alliance common
stock over which each has voting control in favor of the approval and adoption
of the merger agreement and the transactions contemplated thereby. See "The
Merger-- Stockholders' Agreement."
    
 
   
    PERFORMANCE SHARES.  Mr. Fiore and Grant M. Sadler have purchased certain
shares of Gentle Dental common stock, subject to the right of Gentle Dental to
repurchase the unvested portion of such shares in the event certain performance
criteria are not achieved in 1997 and 1998. Such performance criteria were not
achieved in 1997 and as a result 16,691 of Mr. Fiore's shares of Gentle Dental
common stock and 112,755 of Mr. Sadler's shares are now subject to the
repurchase option. With respect to 1998, the number of performance shares
subject to the repurchase option for Messrs. Fiore and Sadler, are 16,691 and
112,755, respectively, in the event such performance criteria are not achieved
in 1998.

<PAGE>
RESTRICTIONS ON RESALES BY AFFILIATES
 
   
    The issuance of shares of Wisdom Holdings common stock to holders of Gentle
Dental common stock and Dental Care Alliance common stock in the mergers have
been registered under the Securities Act of 1933, as amended. The shares of
Wisdom Holdings common stock issued in the mergers may be traded freely without
restrictions by those stockholders not deemed to be "affiliates" of Gentle
Dental or Dental Care Alliance as that term is defined under the Securities Act.
An affiliate of Gentle Dental or Dental Care Alliance, as defined by the rules
promulgated pursuant to the Securities Act, is a person who, directly or
indirectly through one or more intermediaries, controls, is controlled by, or is
under common control with, Gentle Dental or Dental Care Alliance. Any subsequent
transfer of such shares of Wisdom Holdings, however, by any person who is an
affiliate of Gentle Dental or Dental Care Alliance at the time the mergers are
submitted for vote of the holders of Gentle Dental capital stock and Dental Care
Alliance common stock, respectively, will, under existing law, require:
    
 
   
    - the further registration under the Securities Act of the shares of Wisdom
      Holdings common stock to be transferred;
    
 
   
    - compliance with Rule 145 promulgated under the Securities Act (permitting
      limited sales under certain circumstances); or
    
 
   
    - the availability of another exemption from registration.
    
 
   
    The foregoing restrictions are expected to apply to the directors and
executive officers of Gentle Dental and Dental Care Alliance and the holders of
10% or more of any class of Gentle Dental capital stock or the Dental Care
Alliance common stock (and to certain relatives or the spouse of any such person
and any trusts, estates, corporations or other entities in which any such person
has a 10% or greater beneficial or equity interest).
    
 
   
    Stock transfer instructions will be given by Wisdom Holdings to its transfer
agent with respect to the Wisdom Holdings common stock to be received by persons
subject to the restrictions described above, and the certificates for such stock
will be appropriately legended.
    
 
   
    The Securities and Exchange Commission guidelines regarding qualifying for
the "pooling-of-interests" method of accounting also limit sales of shares of
the acquiring and acquired company by affiliates of either company in a business
combination. These Securities and Exchange Commission guidelines provide further
that the "pooling-of-interests" method of accounting generally will not be
challenged on the basis of sales by affiliates of the acquiring or acquired
company if such affiliates do not dispose of any of the shares of the
corporation they own or shares of a corporation they receive in connection with
a merger during the period beginning 30 days before the merger and ending when
financial results covering at least 30 days of post-merger operations of the
combined entity have been published.
    
 
   
    Each of Gentle Dental and Dental Care Alliance has agreed in the merger
agreement to use its best efforts to cause each person who is an affiliate (for
purposes of Rule 145 and for purposes of qualifying the mergers for
"pooling-of-interests" accounting treatment) of such party to deliver to the
other party an "affiliate representation letter" intended to ensure compliance
with the Securities Act and preserve the ability to treat the mergers as a
"pooling-of-interests."
    
 
   
    Wisdom Holdings has agreed in the merger agreement to use its best efforts
to publish, not later than 90 days after the end of the first month after the
effective time in which there are at least 30 days of post-merger combined
operations, combined sales and net income figures as contemplated by and in
accordance with the terms of the Securities and Exchange Commission's Accounting
Series Release No. 135.
    
 
THE STOCKHOLDERS' AGREEMENT
 
   
    Gentle Dental and Dental Care Alliance have each entered into a
Stockholders' Agreement with certain significant stockholders and current
directors and or officers. These stockholders, holding in the
    
 
                                       59
<PAGE>
   
aggregate shares representing approximately     % of the total voting power of
Gentle Dental capital stock and     % of the total voting power of Dental Care
Alliance common stock as of their respective record dates, each have agreed, as
a condition to Gentle Dental and Dental Care Alliance entering into the merger
agreement to vote or to cause to be voted, or to execute a written consent with
respect to, all of such stockholder's shares of common stock then held of record
or beneficially owned, directly or indirectly, in favor of adoption and approval
of the merger agreement and the mergers at every meeting of stockholders at
which such matters are considered and at every adjournment thereof and in
connection with every proposal to take action by written consent with respect
thereto.
    
 
   
    Each Stockholders' Agreement also provides that the stockholder will not,
and will not permit any entity under its control to, deposit any of such
stockholder's shares in a voting trust or subject any such shares to any
agreement, arrangement or understanding with respect to the voting of such
shares inconsistent with the Stockholders' Agreement entered into by that
stockholder.
    
 
   
    The Stockholders' Agreements will terminate upon the earlier to occur of the
completion of the mergers (except for certain provisions which will survive the
completion of the mergers) and the date on which the merger agreement is
terminated in accordance with its terms.
    
 
   
    The Stockholders' Agreement binds the action of the signatories thereto only
in their capacity as Gentle Dental and Dental Care Alliance stockholders. Those
directors of Gentle Dental and Dental Care Alliance who signed stockholders'
agreement are not and could not be contractually bound to abrogate their
fiduciary duties as directors of Gentle Dental and Dental Care Alliance.
Accordingly, while such stockholders/directors are, under the stockholders'
agreement executed by them, contractually bound to vote as Gentle Dental and
Dental Care Alliance stockholders in favor of the mergers, their fiduciary
duties as Gentle Dental and Dental Care Alliance directors nevertheless require
them to act in their capacity as directors in the best interest of Gentle Dental

                  OPERATIONS AND MANAGEMENT OF WISDOM HOLDINGS
                               AFTER THE MERGERS
    
 
OPERATIONS
 
   
    From and after the effective time, each of Gentle Dental and Dental Care
Alliance will be a wholly-owned operating subsidiary of Wisdom Holdings. The
primary business operations conducted by each of the companies, including
existing relationships with affiliated dental practices, will continue following
the mergers. These operations will be conducted by Gentle Dental and Dental Care
Alliance as wholly-owned subsidiaries of the new holding company. However,
certain management functions will be centralized at the new holding company.
    
 
   
    In addition, the $30.0 million of Gentle Dental convertible subordinated
debt will be transferred to and become an obligation of the new company. It is
also anticipated that the new company will become a guarantor and obligor of
Gentle Dental's $45.0 million credit facility. For a discussion of the treatment
of outstanding securities of the companies as a result of the mergers, see
"Exchange of Stock; Treatment of Options and Other Rights to Acquire Capital
Stock" at page 44.
    
 
   
    Wisdom Holdings' main corporate offices will be located at the current
offices of Gentle Dental in El Segundo, California. Wisdom Holdings' East Coast
regional office will be located at the current corporate offices of Dental Care
Alliance in Sarasota, Florida. Wisdom Holdings' West Coast regional office will
be located in Vancouver, Washington. Wisdom Holdings expects that decisions as
to the continuing employment of Gentle Dental and Dental Care Alliance
employees, (except for certain rights retained by Dr. Matzkin for a period of
four years from the effective time with respect to the termination of employment
of certain executive officers of Wisdom Holdings who were previously employed by
Dental Care Alliance) and the continuing operation of business at each of its
facilities, will be made on a case-by-case basis after the effective time based
upon its evaluation of the combined operations of the two companies.

GENTLE DENTAL'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
  RESULTS OF OPERATIONS
 
   
    The following discussion of the results of operations and financial
condition of Gentle Dental should be read in conjunction with Gentle Dental's
audited financial statements and the notes thereto included elsewhere in this
document.
    
 
   
RESULTS OF OPERATIONS
    
 
   
    Gentle Dental reports dental practice net patient revenue and associated
clinical salaries and benefits costs in those instances where Gentle Dental
meets certain specific consolidation requirements established by the Emerging
Issues Task Force of the Financial Accounting Standards Board. In those
instances where such consolidation requirements are not met, Gentle Dental
reports net management fees revenue and does not record any associated clinical
salaries and benefits costs. Through December 31, 1997, certain affiliations in
Oregon and Washington (representing a significant portion of overall net patient
revenues) were not included within Gentle Dental's consolidated financial
statements, as the consolidation requirements described above were not met. As
of January 1, 1998, Gentle Dental entered into new management service agreements
with such affiliations. Consequently, all of the dental practices affiliated
with Gentle Dental, except one, are now accounted for under the consolidation
requirements described above. The remaining dental practice, acquired effective
April 1, 1997, has not met the Emerging Issues Task Force consolidation
requirements.
    
 
   
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1997
    
 
   
    DENTAL PRACTICE NET PATIENT SERVICE REVENUE AND NET MANAGEMENT FEES.  Dental
practice net patient revenue increased from $3.7 million for the year ended
December 31, 1996 to $29.3 million for the year ended December 31, 1997. This
692% growth was due to five affiliations completed in 1996 and six affiliations
completed in 1997, representing 23 clinical locations. These affiliations have
management agreements that meet the Emerging Issues Task Force consolidation
requirements.
    
 
   
    Net management fee revenue represents management services to certain
unconsolidated affiliated dental practices. Net management fees revenue
increased 31.4% from $10.7 million for the year ended December 31, 1996 to $14.1
million for the year ended December 31, 1997. This growth was primarily a result
of three affiliations completed in 1997. Also, approximately 15.0% of the
increase in support services revenue was attributable to increases in the
percentages of patient revenue payable under the management agreements with the
Washington and Oregon affiliated dental practices, from 50.0% to 51.0% and 50.0%
to 53.0%, respectively.
    
 
   
    CLINICAL SALARIES AND BENEFITS.  Clinical salaries and benefits costs
include all patient service provider staff compensation and related payroll
costs at the consolidated dental practices, including dentists, hygienists and
dental assistants. Clinical salaries and benefits increased from $1.5 million
for the year ended December 31, 1996 to $13.7 million for the year ended
December 31, 1997. Practice clinical salaries and benefits as a percentage of
dental practice net patient revenue for the years ended December 31, 1996
    
 
                                       67
<PAGE>
   
and 1997 were 40.3% and 46.7%, respectively. The affiliation of dental practices
with Gentle Dental in 1996 and 1997 contributed to these increases.
    
 
   
    PRACTICE NONCLINICAL SALARIES AND BENEFITS.  Practice nonclinical salaries
and benefits costs include all staff compensation and related payroll costs at
the dental facilities other than dentists, hygienists and dental assistants.
Total nonclinical salary costs increased 91% from $4.3 million for the year
ended December 31, 1996 to $8.2 million for the year ended December 31, 1997.
This increase was primarily due to the addition of costs from affiliations
completed during 1996 and 1997.
    
 
   
    DENTAL SUPPLIES AND LAB EXPENSES.  Dental supplies and lab costs increased
122% from $2.8 million for the year ended December 31, 1996 to $6.3 million for
the year ended December 31, 1997. This increase was primarily due to the
addition of costs from affiliations completed during 1996 and 1997.
    
 
   
    PRACTICE OCCUPANCY EXPENSES.  Practice occupancy expenses increased 126%
from $1.6 million for the year ended December 31, 1996 to $3.5 million for the
year ended December 31, 1997. This increase was primarily due to the addition of
costs from affiliations completed during 1996 and 1997.
    
 
   
    PRACTICE SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  These costs include
general office, advertising, professional services (excluding dentistry), travel
and entertainment, local taxes, insurance, and other miscellaneous costs at the
dental facilities. Practice selling, general and administrative expenses
increased 172% from $1.8 million for the year ended December 31, 1996 to $4.9
million for the year ended December 31, 1997. This increase was primarily due to
the addition of costs from affiliations completed during 1996 and 1997.
    
 
   
    CORPORATE SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Corporate selling,
general and administrative expenses increased 90.1% from $3.0 million for the
year ended December 31, 1996 to $5.7 million for the year ended December 31,
1997. The increase in these expenses is the result of putting the infrastructure
in place to accommodate expected future growth, a substantial part of which
occurred in 1997. In addition to such expenses incurred during the year ended
December 31, 1997, Gentle Dental recorded $1.8 million in expenses associated
with the merger of Gentle Dental with GMS Dental Group, Inc. and Gentle Dental's
related restructuring plan.
    
 
   
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense for
the years ended December 31, 1996 and 1997 was $1.0 million $1.8 million,
respectively. This increase was primarily due to the addition of costs from
affiliations completed during 1996 and 1997.
    
 
   
    INTEREST EXPENSE.  Interest expense decreased from 12.8% from $749,000 for
the year ended December 31, 1996 to $653,000 for the year ended December 31,
1997. This decrease resulted from the repayment by Gentle Dental of $4.4 million
in debt with the proceeds from Gentle Dental's initial public offering which was
partly offset by additional debt incurred to complete dental practice
affiliations in 1997.
    
 
   
    PROVISION FOR INCOME TAXES.  For the years ended December 31, 1996 and 1997,
Gentle Dental recognized tax benefits resulting from its taxable losses for
those years. In 1996, the effective tax rate for the tax benefit was lower than
the statutory rate due to the tax-free merger structure of certain dental
practice affiliations. As a result, the amortization of certain intangible
assets reduced earnings, but was not deductible for tax purposes. In 1997, the
tax benefit was reduced primarily by the valuation allowance for the net
operating loss carry-forward.
    
 
   
NINE MONTHS ENDED SEPTEMBER 30, 1997 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
  1998
    
 
   
    DENTAL PRACTICE NET PATIENT SERVICE REVENUE AND NET MANAGEMENT FEES.  Dental
practice net patient revenue increased from $19.8 million for the nine months
ended September 30, 1997 to $67.5 million for the nine months ended September
30, 1998, an increase of 241%. Of this growth, approximately $25.0 million is
due to five affiliations completed during the second half of 1997 and ten
affiliations completed
    
 
                                       68
<PAGE>
   
during the nine months ended September 30, 1998, representing forty-nine current
clinical locations. These affiliations have management services agreements that
meet the Emerging Issues Task Force consolidation requirements. The remaining
growth of $22.7 million is due to consolidating the operating results of certain
Oregon and Washington affiliations during 1998 as a result of their new
management services agreements dated January 1, 1998 meeting the EITF criteria
for consolidation.
    
 
   
    Net management fees decreased from $10.1 million for the nine months ended
September 30, 1997 to $1.4 million for the nine months ended September 30, 1998.
This decrease is directly related to Gentle Dental consolidating the operating
results of the Oregon and Washington affiliations discussed above, thereby
eliminating management fees revenue in the consolidated financial statements.
Currently, there is one remaining affiliation that does not meet the Emerging
Issues Task Force criteria for consolidation.
    
 
   
    CLINICAL SALARIES AND BENEFITS.  Clinical salaries and benefits increased
233% from $9.2 million for nine months ended September 30, 1997 to $30.8 million
for the nine months ended September 30, 1998. Of this growth, approximately
$11.5 million is due to five affiliations completed during the second half of
1997 and ten affiliations completed during the nine months ended September 30,
1998, representing forty-nine current clinical locations. These affiliations
have management services agreements that meet the Emerging Issues Task Force
consolidation requirements. The remaining growth of $10.1 million is due to
consolidating the operating results of certain Oregon and Washington
affiliations during 1998.
    
 
   
    Practice clinical salaries and benefits as a percentage of dental practice
net patient revenue for the nine months ended September 30, 1997 and 1998 were
47.7% and 45.6%, respectively. Consolidating the operating results of the Oregon
and Washington affiliations and the affiliation of dental practices with Gentle
Dental in the second half of 1997 and the nine months ended September 30, 1998
contributed to this percentage decrease.
    
 
   
    PRACTICE NONCLINICAL SALARIES AND BENEFITS.  Practice nonclinical salaries
and benefits costs increased 73.9% from $5.8 million for the nine months ended
September 30, 1997 to $10.0 million for the nine months ended September 30,
1998. This increase was primarily due to the addition of costs from affiliations
completed during the second half of 1997 and during the nine months ended
September 30, 1998.
    
 
   
    DENTAL SUPPLIES AND LAB EXPENSES.  Dental supplies and lab costs increased
76.0% from $4.5 million for nine months ended September 30, 1997 to $8.0 million
for the nine months ended September 30, 1998. This increase was primarily due to
the addition of costs from affiliations completed during the second half of 1997
and the nine months ended September 30, 1998.
    
 
   
    PRACTICE OCCUPANCY EXPENSES.  Practice occupancy expenses increased 59.2%
from $2.4 million for the nine months ended September 30, 1997 to $3.8 million
for the nine months ended September 30, 1998. This increase was primarily due to
the addition of costs from affiliations completed during the second half of 1997
and the nine months ended September 30, 1998.
    
 
   
    PRACTICE SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Practice selling,
general and administrative expenses increased 103% from $3.2 million for the
nine months ended September 30, 1997 to $6.4 million for the nine months ended
September 30, 1998. This increase was primarily due to the addition of costs
from affiliations completed during the second half of 1997 and the nine months
ended September 30, 1998.
    
 
   
    CORPORATE SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Corporate selling,
general and administrative expenses increased 17.1% from $3.9 million for the
nine months ended September 30, 1997 to $4.5 million for the nine months ended
September 30, 1998. The increase in these expenses is the result of putting the
infrastructure in place to accommodate expected future growth.
    
 
   
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense for
the nine months ended September 30, 1997 and 1998 was $1.3 million and $2.9
million, respectively. This increase was primarily
    
 
                                       69
<PAGE>
   
due to the addition of costs from affiliations completed during the second half
of 1997 and the nine months September 30, 1998.
    
 
   
    INTEREST EXPENSE, NET.  Interest expense increased from $362,000 for the
nine months ended September 30, 1997 to $1.8 million for the nine months ended
September 30, 1998. This increase in interest expense was due to additional debt
incurred under Gentle Dental's credit facility and private placement to complete
certain dental practice affiliations.
    
 
   
    PROVISION FOR INCOME TAXES.  For the nine months ended September 30, 1997
Gentle Dental recognized no tax benefit resulting from its taxable loss as the
probable utilization of any loss carryforwards was uncertain. For the nine
months ended September 30, 1998, Gentle Dental did not accrue a provision for
income taxes as management believes that Gentle Dental will be able to utilize
available federal and state tax loss carryforwards. The income tax expense
recorded during the nine months ended September 30, 1998 represents incidental
filing fees for various federal and state income tax returns.
    
 
   
LIQUIDITY AND CAPITAL RESOURCES
    
 
   
    At September 30, 1998, Gentle Dental's cash and cash equivalents were $1.8
million, representing a $1.5 million increase in cash and cash equivalents
available at December 31, 1997 of $302,000. Working capital at September 30,
1998 of $2.2 million represents a decrease of $616,000 from working capital of
$2.8 million at December 31, 1997. The decrease is the result of the use of
working capital for acquisitions.
    
 
   
    Net cash provided by operations was $902,000 and $174,000 for the nine
months ended September 30, 1997 and 1998, respectively. The reduction of net
cash provided by operating activities during the nine months ended September 30,
1998 was directly attributable to the reduction of accounts payable and accrued
liabilities outstanding at December 31, 1997. The significant level of such
liabilities at December 31, 1997 was attributed to merger and restructure plan
related costs between Gentle Dental and GMS Dental Group, Inc. as a result of
the merger effective in November 1997. The remaining liabilities related to the
restructuring amounted to $195,000 at September 30, 1998. Net cash used in
investing activities, principally dental practice affiliations, was $9.0 million
and $42.6 million for the nine months ended September 30, 1997 and 1998,
respectively. Net cash provided from financing activities was $6.0 million and
$44.0 million for the nine months ended September 30, 1997 and 1998,
respectively. The increase in net cash provided by financing activities during
the nine months ended September 30, 1998 was primarily attributed to the $45
million private placement completed during 1998 as further discussed below.
    
 
   
    On January 1, 1998, Gentle Dental and certain Washington and Oregon
affiliated dental practices entered into asset purchase and management service
agreements. Under the terms of such agreements, Gentle Dental acquired all of
the fixed assets and assumed certain liabilities of such affiliated dental
practices. In exchange, Gentle Dental gave consideration of $1.7 million in
addition to the assumption of certain liabilities, which was offset by Gentle
Dental's $1.7 million receivable from such affiliated dental practices. In
addition, Gentle Dental is required to pay $575,000 in cash over 18 monthly
installments.
    
 
   
    During the nine months ended September 30, 1998, Gentle Dental acquired
substantially all of the assets of 27 dental office locations, including cash,
accounts receivable, supplies and fixed assets. Additionally, Gentle Dental
acquired all of the outstanding capital stock of Managed Dental Care of Oregon,
Inc., a dental care entity that contracts with the Oregon Health Plan. Gentle
Dental also acquired all of the outstanding capital stock of Dedicated Dental
Systems, Inc., a Bakersfield, California company which owns and operates eleven
staff model dental offices under a license granted within the California
Knox-Keene Health Care Service Plan Act of 1975. All such affiliations have been
accounted for using the purchase method of accounting.
    
 
   
    Gentle Dental's credit facility provides for a maximum credit line of $45
million. Gentle Dental intends to use the credit facility for working capital
requirements, to purchase non-professional dental practice assets of additional
dental practices that Gentle Dental may seek to affiliate with, and to purchase
    
 
                                       70
<PAGE>
   
operating assets for existing affiliated dental practices. The ability of Gentle
Dental to incur indebtedness under the credit facility is subject to delivery of
customary opinions, certificates and closing documents by Gentle Dental. The
revolving feature of the credit facility expires on September 30, 2001, at which
time it will convert into a four year term loan to be repaid in 16 equal
quarterly installments. Principal amounts owed under the credit facility bear
interest, at Gentle Dental's option at varying margins over LIBOR (1%-1.75%) or
the prime rate (0.5%-1%), at Gentle Dental's option, based on the level of
Gentle Dental's leverage ratio. The credit facility requires Gentle Dental to
pay an unused commitment fee in an amount of ranging from 0.375% to 0.750% per
annum (depending on amounts of unused available credit) on the average daily
amount by which the bank commitment under the credit facility exceeds the
aggregate amount of all loans then outstanding. The credit facility contains
several covenants including (i) restrictions on the ability of Gentle Dental to
incur indebtedness and repurchase, or make dividends with respect to, its
capital stock; and (ii) requirements relating to maintenance of a specified net
worth and compliance with specified financial ratios. In addition, the credit
facility requires Gentle Dental to notify the lenders prior to making any
acquisition and to obtain the consent of the lenders prior to making
acquisitions with purchase prices exceeding $12 million or when cash
consideration exceeds $7.5 million. The credit facility also requires Gentle
Dental to convert to a holding company that owns no assets other than the stock
of its subsidiaries on or before July 31, 1999. Gentle Dental's obligations
under the credit facility are guaranteed by each of its non-dental insurance
business subsidiaries. The obligations of Gentle Dental under the credit
facility and the subsidiaries under the guarantees are secured by a security
interest in the equipment, fixtures, inventory, receivables, subsidiary stock,
certain debt instruments, accounts and general intangibles of each of such
entities.
    
 
   
    On June 3, 1998, Gentle Dental completed a $45 million private placement,
consisting of $30 million of subordinated notes and $15 million of preferred
stock of Gentle Dental. The subordinated notes have eight year terms and are
convertible into shares of Gentle Dental common stock at $9.21 for each share of
common stock issuable upon conversion of outstanding principal and accrued but
unpaid interest on such subordinated notes. If certain events of default occur,
the subordinated notes then outstanding will automatically convert into shares
of Gentle Dental Series B preferred stock at a rate of one share of Gentle
Dental Series B preferred stock for each thousand dollars in outstanding
principal and accrued but unpaid interest on the subordinated notes, subject to
adjustment for stock splits, reverse splits, stock dividends, reorganizations
and the like. The subordinated notes and all outstanding shares of Gentle Dental
preferred stock shall be automatically converted into Gentle Dental common stock
(or, in the case of the Gentle Dental Series A preferred stock and Gentle Dental
Series C preferred stock, redeemed at nominal cost) if the rolling 21-day
average closing market price of the common stock on 20 out of any 30 consecutive
trading days is more than $15.73 on or prior to May 18, 1999, more than $16.85
on or prior to May 18, 2000, or more than $17.98 at any time thereafter.
    
 
   
    The presently authorized series of Gentle Dental preferred stock include the
following series: 100 shares of Gentle Dental Series A preferred stock, all of
which is issued and outstanding; 70,000 shares of Gentle Dental Series B
preferred stock, none of which is presently outstanding but which will be issued
automatically upon conversion of the then outstanding subordinated notes; 100
shares of Gentle Dental Series C preferred stock, all of which is issued and
outstanding; and 2,000,000 shares of Gentle Dental Series D preferred stock of
which 1,628,663 shares are issued and outstanding. The shares of convertible
Gentle Dental Series B preferred stock are convertible into shares of Gentle
Dental common stock at the rate of 108.58 shares of Gentle Dental common stock
for each share of Gentle Dental Series B preferred stock, and the shares of
Gentle Dental Series D preferred stock are convertible into shares of Gentle
Dental common stock on a share for share basis, in each case subject to
adjustment for stock splits, reverse splits, stock dividends, reorganizations
and the like. The Gentle Dental Series A preferred stock and Series C preferred
stock are not convertible.
    
 
   
    Gentle Dental believes that proceeds from its existing credit facility and
cash flow from operations, if any, will be sufficient to fund its operations for
the near future. Gentle Dental also believes that such funds
    
 
                                       71
<PAGE>
   
will be sufficient to complete a number of other future dental practice
affiliations and any possible future consideration from existing affiliations.
However, to execute its long term business strategy, Gentle Dental will require
substantial additional funding through additional long-term or short-term
borrowing arrangements or through the public or private issuance of additional
debt or equity securities to affiliate new practices and to expand and maintain
existing affiliated practices. There can be no assurance that any such financing
will be available to Gentle Dental or will be available on terms acceptable to
Gentle Dental.
    
 
RECENT DEVELOPMENTS
 
   
    On October 30, 1998, Gentle Dental acquired all of the issued and
outstanding shares of capital stock of Capitol Dental Care, Inc., an Oregon
corporation, and purchased substantially all of the assets of Dental Maintenance
of Oregon, P.C., an Oregon professional corporation, and entered into a
management agreement with Dental Maintenance of Oregon, P.C., whereby Gentle
Dental would provide management and administrative service to the dental
practice. As consideration for purchase of the stock of Capitol Dental Care,
Inc., Gentle Dental issued a promissory note in the amount of $800,000, bearing
interest at the annual rate of 8% and payable in equal quarterly installments of
principal and interest. As consideration for purchase of the assets of Dental
Maintenance of Oregon, P.C., Gentle Dental paid $6.0 million in cash, and issued
a $1.7 million promissory note payable in equal quarterly installments of
principal and interest over a three year term with an annual interest rate of
8%. Dental Management of Oregon, P.C., can earn additional cash consideration if
its earnings increase over a two-year period based on a formula described in the
acquisition agreements.
    
 
   
    Capitol Dental Care, Inc. provides capitated dental services under the
Oregon Health Plan governed by a contract with the State of Oregon Office of
Medical Assistance Programs. Dental Maintenance of Oregon, P.C. is a dental
practice with nine offices which provides professional dental care to patients
and which also subcontracts with Capitol Dental Care, Inc. to provide
professional dental services to beneficiaries under the Oregon Health Plan.
    
 
   
    In connection with certain completed affiliation transactions, Gentle Dental
agreed to pay to the sellers possible future consideration in the form of cash
and Gentle Dental capital stock. The amount of future consideration payable by
Gentle Dental under earn-outs is generally computed based upon financial
performance of the affiliated dental practices during certain specified periods.
Gentle Dental accrues for earn-out payments with respect to prior practice
acquisitions when such amounts are probable and reasonably estimable. As of
September 30, 1998, Gentle Dental had accrued $1.8 million for future earn-out
payments, of which $578,000 is included in additional paid-in capital for
anticipated stock issuances while the remaining accrual for anticipated cash
payments is included in other current liabilities. For those acquisitions with
earn-out provisions, Gentle Dental estimates the total maximum earn-out to be
paid, including amounts already accrued, is between $15 and $20 million from
November, 1998 to December, 2002, of which up to $15 million is expected to be
paid in cash.
    
 
   
    A total of 254,901 outstanding shares of Gentle Dental common stock issued
at a price of $.45 per share and 339,246 outstanding shares of Gentle Dental
common stock issued at a price of $.225 per share are subject to, under certain
events, repurchase by Gentle Dental at cost. One-half of these shares are
currently subject to repurchase as a result of Gentle Dental's failure to
achieve certain specified performance targets during 1997 and are expected to be
repurchased in the future.
    
 
   
YEAR 2000 COMPLIANCE
    
 
   
    Many existing computer programs use only two digits to identify a year in a
data field. These programs were designed and developed without considering the
impact of the upcoming change in the century. If not corrected, many computer
applications could fail or create erroneous results by or at the Year 2000 or
earlier. The Year 2000 issue affects us in that the dental practice management
business is dependent on computer applications, such as management information
systems and financial and accounting systems.
    
 
                                       72
<PAGE>
   
    In order to address the Year 2000 issues facing Gentle Dental, management
initiated a program to prepare Gentle Dental's computer systems and applications
for the Year 2000. As to the primary focus of its Year 2000 plans, Gentle Dental
has converted its affiliated dental practices to target systems identified and
believed to be Year 2000 compliant. Gentle Dental has divided its Year 2000 plan
into five phases, and charts its progress in each of the phases, expressed as an
approximate percentage of completion of that phase:

Implementation..........................................................              50%
</TABLE>
    
 
   
    Pursuant to its Year 2000 plan, Gentle Dental expects to substantially
complete validation of its mission critical systems and the computer-related
interactive vendor systems by December 31, 1998 and complete all validation by
June 1999. In addition, Gentle Dental expects to complete all phases of its Year
2000 plan by June 30, 1999.
    
 
   
    Gentle Dental expects to incur internal staff costs as well as consulting
and other expenses related to infrastructure enhancements necessary to prepare
for the Year 2000. Validation and conversion of primary system applications and
hardware is expected to cost approximately $500,000, all of which will be
incurred in fiscal year 1999.
    
 
   
    As part of its Year 2000 plan, Gentle Dental is not only undertaking the
infrastructure and facilities enhancement and testing necessary to ensure that
it adequately prepared for the Year 2000, but is also communicating with its
vendors upon whose services it relies and third-party payors to ensure that such
vendors and third-party payors are taking appropriate steps to address their
Year 2000 issues. Gentle Dental is also preparing contingency plans to try to
minimize the harm to it in the event that it or any or all of the third parties
with which it interacts is unable to attain Year 2000 compliance in certain
applications according to Gentle Dental's Year 2000 plan. The contingency plans
being prepared are system and application specific and are intended to ensure
that in the event that one or more of such systems and/or applications fails by
or at the Year 2000, Gentle Dental will be able to engage in its core business
functions in spite of such failure. Gentle Dental's most likely worst case Year
2000 scenario would be that it experiences significant delays in billing and
collecting professional fees due its affiliated dental practices. This delay
would directly impact the ability of the affiliated dental practices to pay the
management fees due the company. A material delay in receipt of fees due Gentle
Dental would affect its cash flow and could have a material adverse effect on
its business, financial condition or results of operations.
    
 
   
    Although Gentle Dental believes that its Year 2000 plan and other steps
being taken are adequate to ensure that it will not be materially affected by
the Year 2000 problem, there can be no assurance that the Year 2000 plan and
Gentle Dental's other Year 2000 remedial and contingency plans will fully
protect it from the risks associated with the Year 2000 problem. The analysis
of, and preparation for, the Year 2000 and related problems necessarily rely on
a variety of assumptions about future events, and there can be no assurance that
management has accurately predicted such future events or that the remedial and
contingency plans for Gentle Dental will adequately address such future events.
In the event that the business of Gentle Dental or Gentle Dental's vendor or
patients are disrupted as a result of the Year 2000 problem such disruption
could have a material adverse effect on Gentle Dental.
    
 
CERTAIN TRANSACTIONS REGARDING GENTLE DENTAL
 
   
    The outstanding capital stock of certain professional corporations located
in Oregon and Washington is owned in whole or in part by Dany Y. Tse and Gerald
R. Aaron, each of a director and/or executive
    
 
                                       73
<PAGE>
   
officer of Gentle Dental. Gentle Dental is a party to certain management
agreements with each of these professional corporations pursuant to which Gentle
Dental earns a significant portion of its revenues. Effective January 1, 1998,
Gentle Dental entered into agreements to amend these management agreements to
conform them to the existing management agreements of dental practices
historically affiliated with GMS Dental Group, Inc. and to increase Gentle
Dental's control over these professional corporations. As consideration for
entering into the amended management agreements, Gentle Dental agreed to pay to
the Oregon and one of the Washington professional corporations or certain of
their respective designated dental practitioners, in the aggregate, the
following:
    
 
   
    - approximately $1.7 million in cash offset by approximately $1.7 million of
      Gentle Dental receivables due from such professional corporations;
    
 
   
    - the right to receive an aggregate of either $575,000 in cash in 18 equal
      monthly installments or options to acquire 230,000 shares of Gentle Dental
      common stock at an exercise price of $8.375 per share, subject to five
      year vesting, plus options to acquire an aggregate of 110,000 shares of
      Gentle Dental common stock exercisable at $8.375 per share, subject to
      five year vesting; and
    
 
   
    - future cash or options subject to five year vesting in amounts to be
      determined according to a formula based upon the operating revenues of
      such Oregon and Washington professional corporations for fiscal years
      ending December 31, 1998 and 1999.
    
 
   
    On May 31, 1996, Gentle Dental executed a modification of its former loan
and security agreement with Silicon Valley Bank. In connection with the
modification, 14 officers, directors, and shareholders of Gentle Dental
including Dr. Tse, Dr. Wong and Mr. Van Eerden, provided continuing personal
guarantees on $1,000,000 of Gentle Dental's indebtedness to Silicon Valley Bank
in connection with a $1,000,000 increase in availability under such credit
facility. In consideration for the personal guarantees, Gentle Dental issued
warrants to purchase an aggregate total of 115,000 shares of Gentle Dental
common stock at $7.50 per share. Each guarantor received warrants to purchase
1,150 shares of Gentle Dental common stock for each $10,000 of indebtedness
guaranteed. All of these guarantees terminated in February 1997 upon the
repayment of the loan.
    
 
   
    On April 1, 1997, Mr. Fiore was granted stock options by GMS Dental Group,
Inc. exercisable for 750,000 shares of GMS Dental Group, Inc. common stock at an
aggregate exercise price of $150,000. On the same date, Mr. Fiore exercised the
options for all such shares. The exercise price was paid in the form of a
secured promissory note in the principal amount of $150,000 which bears annual
interest at the rate of 6.84% compounded annually. All unpaid principal and
accrued interest becomes due and payable to Gentle Dental on March 31, 2001. In
the merger of GMS Dental Group, Inc. with and into Gentle Dental, the shares
purchased on exercise of Mr. Fiore's options were converted into 333,816 shares
of Gentle Dental common stock. Of these shares, 300,434 shares are subject to a
four year vesting schedule under which 25% of the shares vested on April 1, 1998
and the remaining shares vest in equal amounts over the next 36 months. All
unvested shares are subject to repurchase by Gentle Dental at $0.45 per share
upon termination of Mr. Fiore's service to Gentle Dental for cause. The unvested
shares will become fully vested in the event Mr. Fiore's service to Gentle
Dental is terminated for any reason other than for cause. Of the remaining
33,382 shares of Gentle Dental common stock held by Mr. Fiore, one half are
currently subject to repurchase by Gentle Dental at $0.45 per share because
Gentle Dental's EBITDA (excluding CEO salary and related expense) for 1997 did
not exceed $4,723,500. The second half of the remaining shares are subject to
repurchase by Gentle Dental at the same price if, among other things, Gentle
Dental's EBITDA (excluding CEO salary and related expense) for 1998 does not
exceed $12,683,250, and a portion of the second half will be subject to
repurchase if such EBITDA does not exceed $16,911,000.
    
 
   
    In 1996, Mr. Sadler purchased from GMS Dental Group, Inc. 888,681 shares of
GMS Dental Group, Inc. common stock for $88,868. The purchase price was paid in
part in the form of a secured promissory note in the principal amount of
$87,911, which bears interest at the rate of 6.84%, compounded annually. All
unpaid principal and accrued interest on such promissory note becomes due and
payable on August 31, 2000. In the merger of GMS Dental Group, Inc. with and
into Gentle Dental, the foregoing shares were
    
 
                                       74
<PAGE>
   
converted into 395,541 shares of Gentle Dental common stock. Of these shares,
175,031 shares are subject to a four year vesting schedule under which one
fourth of the shares vested immediately upon issuance, another one fourth vested
on October 11, 1997 and the remaining shares vest in equal amounts over the next
36 months thereafter. All unvested shares are subject to repurchase by Gentle
Dental at $0.225 per share upon termination of Mr. Sadler's service to Gentle
Dental for any reason. In addition, 110,255 shares of common stock held by Mr.
Sadler are currently subject to repurchase by Gentle Dental at $0.225 per share
because Gentle Dental's EBITDA (excluding CEO salary and related expense) for
1997 did not exceed $4,723,500. Another 110,255 shares are subject to repurchase
by Gentle Dental at the same price if, among other things, Gentle Dental's
EBITDA (excluding CEO salary and related expense) for 1998 does not exceed
$12,683,250, and a portion of those shares will be subject to repurchase if such
EBITDA does not exceed $16,911,000.
    
 
    An additional 340,255 shares of common stock held by certain other former
GMS Dental Group, Inc. stockholders (including 42,060 shares held by Sprout
Capital VII and certain related entities) are also subject to repurchase by
Gentle Dental at an average price of $0.37 per share ($.45 per share for Sprout
Capital VII L.P. and certain related entities). One half of the shares are
currently subject to repurchase because Gentle Dental's EBITDA (excluding CEO
salary and related expense) for 1997 did not exceed $4,723,500. The second half
of the shares are subject to repurchase if, among other things, Gentle Dental's
EBITDA (excluding CEO salary and related expense) for 1998 does not exceed
$12,683,250, and a portion of the second half will be subject to repurchase if
such EBITDA does not exceed $16,911,000.
 
   
    Gentle Dental has entered into employment agreements, dated as of June 1,
1998, with Michael T. Fiore, Gentle Dental's President and Chief Executive
Officer, and with L. Theodore Van Eerden, its Executive Vice President and Chief
Development Officer. Under these employment agreements, the annual base salaries
of Messrs. Fiore and Van Eerden are $250,000 and $140,000, respectively. The
executive officers are also entitled to participate in bonus plans maintained or
established by Gentle Dental. The employment agreements for Mr. Fiore and Mr.
Van Eerden are "at-will" in that either the employee or Gentle Dental can
terminate the employee's employment at any time for any reason, with or without
cause. Mr. Fiore and Mr. Van Eerden are each entitled to severance payments
based on their base salaries for 18 months and 12 months, respectively, if their
employment is terminated by Gentle Dental without "cause" or if they voluntarily
terminate their employment for "good reason."
    
 
    For purposes of each of the employment agreements, "cause" means
   
    - the employee's continuous and willful inattention to employee's duties
      after at least one written notice has been given to employee and employee
      has been given an opportunity to correct the problem within thirty days
      after such notice;
    
 
   
    - any breach by employee of certain sections of the employment agreement
      relating to covenants of non-solicitation, non-competition and
      confidentiality;
    
 
   
    - any act committed by employee with respect to the property or the business
      of Gentle Dental which constitutes gross recklessness, willful or gross
      misconduct or fraud; or
    
 
   
    - criminal conduct which has caused material injury to Gentle Dental and
      which could reasonably result in conviction of a felony which involves
      fraud, dishonesty or moral turpitude.
    
 
   
    The employee shall not be considered to have been terminated for "cause" if
terminated by Gentle Dental solely:
    
 
   
    - as a result of employee's bad judgment or negligence;
    
 
   
    - because of any act or omission believed by employee in good faith to have
      been in or not opposed to the best interests of Gentle Dental (without the
      intent of gaining directly or indirectly a profit to which employee was
      not legally entitled) and reasonably believed by employee not to have been
      improper or unlawful;
    
 
                                       75
<PAGE>
   
    - because of an act or omission for which a determination could properly
      have been made by the Board of Directors that employee met the applicable
      standard of conduct prescribed for indemnification or reimbursement under
      the bylaws or charter of Gentle Dental, or the laws of the State of
      Washington, in each case in effect at the time of such acts or omissions;
      or
    
 
   
    - because of any act or omission for which notice of termination is given
      more than twelve months after the earliest date on which a non-employee
      director of Gentle Dental who is not a party to such act or omission knew
      or should have known of such act or omission.
    
 
   
    For purposes of each of the employment agreements, "good reason" shall mean
termination of employee's employment by employee within thirty days following:
    
 
   
    - any relocation of Gentle Dental's executive offices where employee is
      employed at a new location which is in excess of 25 miles from its current
      location;
    
 
   
    - a demotion in position from the employee's positions with Gentle Dental as
      of the date the employment agreement was executed; or
    
 
   
    - the assignment of duties and responsibilities of materially lesser status,
      dignity and character, or a substantial reduction in the nature or status
      of employee's duties and responsibilities.
    
 
   
    Gentle Dental also entered into an employment agreement, dated as of July 1,
1998, with Dany Y. Tse, DMD, Gentle Dental's Co-Chairman of the Board and
President of Clinical Services Council. Under that employment agreement, Dr.
Tse's annual base salary was $243,000. The employment agreement for Dr. Tse
provided for an initial term through June 30, 2003, subject to a renewal term
through June 30, 2008, and further provided that Dr. Tse may not be terminated
without cause prior to April 30, 2002 and that after April 30, 2002, Dr. Tse's
employment will be at-will. Pursuant to his employment agreement, if Dr. Tse
voluntarily terminated his employment for "good reason" prior to July 1, 2001,
he would have been entitled to enter into a 12-month consulting agreement at his
base salary; upon termination of the 12-month consulting agreement, Dr. Tse
would have been entitled to severance payments for 24 months based on his base
salary. If Dr. Tse voluntarily terminated his employment for "good reason" after
July 1, 2001, Dr. Tse would have been entitled to enter into a 12-month
consulting agreement at his base salary; upon termination of the 12-month
consulting agreement, Dr. Tse would have been entitled to severance payments for
12 months based on his base salary. If Gentle Dental terminated Dr. Tse's
employment without "cause" after April 30, 2002, Dr. Tse would have been
entitled to receive severance payments based on his base salary for the period
through June 30, 2003.
    
 
   
    In the event that:
    
 
   
    - Dr. Tse's employment with Gentle Dental is terminated by Gentle Dental for
      any reason other than "cause",
    
 
   
    - Dr. Tse's employment with Gentle Dental is terminated by Employee for
      "good reason",
    
 
   
    - Dr. Tse's employment with Gentle Dental is terminated because of death or
      physical disability within the meaning of Section 22(e)(3) of the Internal
      Revenue Code of 1986, or
    
 
   
    - a "change in control" of Gentle Dental occurs,
    
 
   
all shares of Gentle Dental's common stock subject to outstanding options or
shares subject to restrictions held by Dr. Tse at the time of the event shall be
fully vested as of the date of such event.
    
 
   
    On December 23, 1998, Gentle Dental and Dr. Tse entered into a Separation
Agreement and Mutual Release whereby Dr. Tse resigned as an employee, officer
and director of Gentle Dental effective as of December 31, 1998. The separation
agreement supersedes and replaces all post-termination obligations of either
party under Dr. Tse's employment agreement. Pursuant to the separation
agreement, Dr. Tse will provide consulting services to the new company from
January 1, 1999 through December 31, 2000. Dr. Tse shall be paid aggregated
consulting payments of $257,580 and $273,035 payable in equal monthly
installments less applicable taxes for the years 1999 and 2000, respectively.
Further, from January 1, 2001
    
 
                                       76
<PAGE>
   
through June 30, 2003, Dr. Tse shall be paid aggregated severance payments of
$289,417, $306,782 and $162,594 payable in equal monthly installments less
applicable taxes for the years 2001, 2002 and 2003, respectively. Additionally,
all stock options to purchase Gentle Dental common stock granted to Dr. Tse will
be fully vested and exercisable on December 31, 1998. With respect to the stock
options granted to Dr. Tse prior to 1998, those options will be exercisable
until March 31, 1999. With respect to the stock options granted to Dr. Tse in
1998, those options will be exercisable until March 31, 2001.
    
 
   
    The above-described transactions with related parties were on terms the
Gentle Dental Board of Directors believed to be fair to Gentle Dental and no
less favorable to Gentle Dental than terms that could have been obtained from an
unrelated party. Future transactions between Gentle Dental and affiliated dental
practices controlled by officers, directors, and principal shareholders of
Gentle Dental will be carried out pursuant to a related party transaction policy
adopted by the Gentle Dental Board of Directors. The policy provides that any
transaction between Gentle Dental and (a) an officer, director, or principal
shareholder of Gentle Dental or (b) any entity that is controlled by officers,
directors, or principal shareholders of Gentle Dental must be approved by at
least a majority of the members of the Gentle Dental Board of Directors who do
not have an interest in the transaction. The terms of such transactions must be
no less favorable to Gentle Dental than those that are generally available from
unaffiliated third parties.
    
 
   
    It is anticipated that upon consummation of the mergers, Mr. Fiore will
enter into a three-year employment agreement with the combined company that will
have substantially the same terms and provisions as contained in his existing
employment agreement with Gentle Dental, but will entitle Mr. Fiore to severance
payments based on his base salary for a period 36 months if he is terminated
without cause or if he terminates his employment for good reason.

                     INFORMATION ABOUT DENTAL CARE ALLIANCE
 
GENERAL
 
    Dental Care Alliance, Inc. was formed on October 23, 1996 to effect a
reorganization among Dental Care Alliance, Golden Care Holdings, the predecessor
to Dental Care Alliance which was incorporated in 1993, and Dental Care
Alliance's majority owned subsidiaries. Dental Care Alliance provides management
 
                                       83
<PAGE>
   
and licensing services to dental practices in Florida, Georgia, Michigan and
Indiana. As of September 30, 1998, Dental Care Alliance provided management and
licensing services to a total of 55 managed dental centers operated by 38
professional corporations and associations. Management and administrative
services provided to dental practices include financial, accounting, billing,
assistance in obtaining third-party financing, training and education of dental
professionals, efficiency and productivity enhancement, recruiting, human
resource management, team building, marketing, advertising, purchasing,
collection, assistance with management information services, quality assurance,
patient scheduling and other services, as well as the provision of management
and administrative personnel. Licensing services include marketing, advertising
and purchasing. Dental Care Alliance does not provide dental services. Dental
Care Alliance currently is expanding in Florida, Georgia, Michigan and Indiana
and intends to expand selectively into new markets.
    
 
   
    The professional associations employ and maintain full control over the
general dental and specialty dental practitioners (such as orthodontists,
periodontists, endodontists and oral surgeons), hygienists and other dental
professionals and set standards of care in order to promote the provision of
high quality dental care. The individual professional associations are
responsible for compliance with state and local regulations of the practice of
dentistry and with licensing and certification requirements, and each
professional association is responsible for acquiring and maintaining
professional liability insurance.
    
 
   
    Almost all of its management agreements provide that Dental Care Alliance:
    
 
   
    - assist in the identification of areas in which the performance of the
      managed dental centers and their dental professionals can be improved to
      increase revenues and operating income;
    
 
   
    - provide, maintain and repair all offices, equipment and furnishings;
    
 
   
    - employ all non-professional personnel necessary for the operation of the
      managed dental centers;
    
 
   
    - provide payroll services;
    
 
   
    - implement standard business systems and procedures and provide or
      facilitate systems and efficiencies training;
    
 
   
    - order all general business inventory and supplies required by the managed
      dental centers and handle accounts payable;
    
   
    - establish and maintain information systems and provide accounting and
      bookkeeping services;
    
 
   
    - monitor compliance with rules and regulations applicable to the managed
      dental centers' business;
    
 
   
    - provide marketing assistance; and
    
 
    - provide assistance in billing and collections, all to the extent permitted
      by law.
 
   
    These management agreements also provide that the professional associations
are responsible for, among other things:
    
 
   
    - employing and supervising all dentists and dental hygienists;
    
 
   
    - complying with all laws, rules and regulations relating to dentists and
      dental hygienists;
    
 
   
    - participating in quality assurance/utilization review programs;
    
 
   
    - maintaining proper dental patient records;
    
 
   
    - obtaining and maintaining professional liability insurance with limits of
      not less than $300,000 per claim and aggregate policy limits of not less
      than $1.0 million; and
    
 
    - any other requirements to carry out the practice of dentistry.
 
                                       84
<PAGE>
   
    As compensation for its management services under the standard management
agreements, the professional associations pay Dental Care Alliance a management
fee equal to 67%-74% of the net collected revenues earned by the professional
association. Dental Care Alliance pays all of the operating and nonoperating
expenses incurred by the professional associations except for:
    
 
   
    - salaries and benefits to the dentists and dental hygienists;
    
 
   
    - licensing fees paid to Dental Care Alliance;
    
 
   
    - debt and asset carrying costs related to the acquisition of the dental
      practice; and
    
 
   
    - any other direct cost to the professional association not covered under
      the management agreement.
    
 
   
    Dental Care Alliance divides the geographic areas in which it operates into
regions, each of which is under the supervision of one or more dentists. The
primary purpose of these dental directors is to promote the provision of high
quality dental care and to refine operating efficiencies at the managed dental
centers. Dental directors continually monitor and evaluate the performance of
the dentists and the managed dental centers within their region by identifying
operational inefficiencies and implementing solutions to address these
inefficiencies. Each dental director performs periodic spot checks in which the
performance of each managed dental center is scrutinized in detail. The dental
directors also assist the professional associations in their region with hiring,
training and supervision of dental professionals. Dental Care Alliance believes
that close relationships among the dental directors, the professional
associations they supervise and Dental Care Alliance allow for the
identification of specific inefficiencies, the quick remediation of such
inefficiencies and the realization of the benefits produced by Dental Care
Alliance's management approach.

(1) Effective October 1996, Dental Care Alliance revised the terms of all of its
    12 then existing management agreements such that Dental Care Alliance is
    responsible for the payment of all non-professional expenses of the managed
    dental centers. Ten management agreements were also revised to base Dental
    Care Alliance's management fee from a percentage of net profits at each
    professional association to a percentage of net patient revenues from each
    professional association. Accordingly, prior to these revisions to such 12
    management agreements, all non-professional expenses of the managed dental
    centers and related revenues were reflected in each professional
    associations financial statements. See "Dental Care Alliance's" Management's

that own the practices. Dental Care Alliance commenced operations in November
1993 by providing management and licensing services to five dental practices
located in Sarasota, Palmetto, Largo, Port Charlotte and Venice, Florida. In
1994, Dental Care Alliance entered into its first management agreement for a
newly developed practice located in Englewood, Florida and entered into a
management agreement to manage an additional existing practice in Fort Myers,
Florida. In 1995, Dental Care Alliance entered into four new management
agreements, two of which were with respect to newly developed practices located
in Kissimmee and Bradenton, Florida and the remaining two of which were with
respect to existing practices located in Sarasota and Port Richey, Florida.
Dental Care Alliance entered into four additional management agreements in 1996
to manage practices located in Orlando, Tampa, Ocoee and Clearwater, Florida. In
addition, Dental Care Alliance terminated its management agreements with respect
to the managed dental centers at Palmetto and Venice in 1995 and in Port Richey
in 1996. In 1997, Dental Care Alliance entered into seventeen additional
    
 
                                       87
<PAGE>
   
management agreements to manage five practices in Michigan and 12 in Florida. As
of September 30, 1998, Dental Care Alliance provided management and licensing
services to 55 managed dental centers, 35 of which are located in Florida, nine
of which are located in Michigan, eight of which are located in Georgia, and
three of which are located in Indiana.
    
 
   
    Prior to October 1996, the management fee paid to Dental Care Alliance
pursuant to the management agreements had been equal to a percentage ranging
from 50-90% of the net profits of the individual managed dental centers plus
reimbursement to Dental Care Alliance of its non-professional expenses.
Effective October 1996, Dental Care Alliance revised all of its 12 then existing
management agreements. Ten of these agreements were revised such that Dental
Care Alliance would earn management fees based on 74% of total net patient
revenues and so that payment would be based on cash collected minus any patient
refunds and Dental Care Alliance would assume responsibility for the payment of
the non-professional expenses of the managed dental centers. The remaining two
management agreements continued to have management fee structures based upon
50-55% of the net profit, as defined, of the two managed dental centers. Since
then, virtually all management agreements have been similar in form to the
revised agreements mentioned above, except that management fees have ranged from
67% to 74% of the net collected revenues.
    
 
   
    Dental Care Alliance will seek to cause future management agreements to be
on terms substantially similar to those of the standard management agreements.
The method by which Dental Care Alliance manages the revenue and profitability
of managed dental centers is fundamentally the same, regardless of whether the
management agreement with any particular professional association provides for a
management fee based upon net profits or net patient revenue. In the "net
profits" type of management agreement, both the professional association owner
and Dental Care Alliance share proportionally in the favorable impact of any
initiatives. In the "net patient revenues" type of management agreement, the
cost benefits resulting from such initiatives accrue to the party responsible
for such costs and both parties share proportionally in revenue enhancements.
Period to period comparisons of Dental Care Alliance's results of operations set
forth below should be considered in light of the significant changes in Dental
Care Alliance's growth and in recognition of revenues and expenses resulting
from the revisions to the management agreements in October 1996.
    
 
   
    Dental Care Alliance believes that certain of the management agreements are
material to Dental Care Alliance as a whole. The managed dental center in Flint,
Michigan, contributed approximately 14% of Dental Care Alliance's aggregate
revenue in 1997 and may contribute in excess of 10% of Dental Care Alliance's
aggregate revenue in 1998. Further, the professional association located in Port
Charlotte, Florida contributed approximately 18% and 9% to Dental Care
Alliance's revenues in 1996 and 1997. The management agreement for the managed
dental center in Flint has a term of 25 years and provides for a management fee
equal to 74% of the net collected revenues earned by the associated professional
association. The management agreement for the managed dental center in Port
Charlotte expires in 2003 and provides for a management fee of 55% of the net
profits of the associated professional association. In addition, the Port
Charlotte management agreement provides that the professional association may,
during the period commencing on October 20, 1998 and ending 90 days thereafter,
terminate the agreement by paying Dental Care Alliance an amount equal to
$185,460 less the amount by which the aggregate fees paid to Dental Care
Alliance pursuant to such management agreement during either or both of the
successive one year periods following October 20, 1996 exceeds $100,000, and
satisfying other conditions set forth therein. The professional association has
indicated that it intends to exercise its option to terminate the agreement
effective February 1, 1999. Dental Care Alliance earned fees of $121,900 for the
year ended December 31, 1997 and $95,700 for the nine months ended September 30,
1998.
    
 
   
    All patient revenues are billed to patients and providers under the
authority and identification numbers of the individual professional
associations. Patient revenues and receivables are recorded on the accounts of
the professional associations. Funds are dispersed initially to pay all the
professional costs of the professional associations. Thereafter, funds are
disbursed to Dental Care Alliance under the terms of
    
 
                                       88
<PAGE>
   
the management agreements. Any remaining funds are retained by the professional
association. If funds are insufficient to pay Dental Care Alliance under the
terms of the relevant management agreement, a payable from the professional
association to Dental Care Alliance is recorded on Dental Care Alliance's books.
    
 
   
    Dental Care Alliance also enters into license agreements with each Dental
Center pursuant to which Dental Care Alliance provides licensing and advertising
services to the Dental Centers. In return for such services, Dental Care
Alliance has collected fees generally ranging from $800 to $1,000 per month from
each managed dental center and $600 from each licensed dental center.
    
 
   
    Historically, in connection with the execution of a management agreement, a
professional association has typically acquired both the dental and the
non-dental assets of a managed dental center. Dental Care Alliance has either
made loans to the acquiring professional association or has assisted the
professional association in obtaining third-party financing to purchase such
assets. Recently, Dental Care Alliance has begun acquiring certain of the
non-dental assets of managed dental centers while the professional associations
acquire the dental assets of such managed dental centers. In addition, due to
changing market conditions, Dental Care Alliance has begun compensating
professional associations for the execution of management agreements.
    
 
   
    Dental Care Alliance from time to time has made loans to newly formed
professional associations with which it has entered into management agreements
to purchase the dental assets of the related dental practices. In return the
professional associations execute promissory notes to Dental Care Alliance in
the amount of such loans. At September 30, 1998, the total outstanding balance
of such loans was $762,430. The notes underlying such loans generally have terms
ranging from two to ten years, bear interest at rates ranging between 8.5% and
18.5% and are secured by the assets of the related dental practice. The
professional associations to which such loans are made are newly formed and have
no assets other than the assets of the dental practices being acquired and no
liabilities other than the liabilities relating to the loans. In addition,
Dental Care Alliance from time to time makes working capital advances to
individual professional associations, although it is not obligated contractually
or otherwise to make such advances. The extension of loans and advances to the
professional associations by Dental Care Alliance is not considered upon
entering into management agreements with Dental Care Alliance. Extension of any
such loans or advances is entirely within Dental Care Alliance's discretion.
These advances are due within 12 months of issuance, bear interest at 8.5%,
subject to adjustment based on changes in the rates at which Dental Care
Alliance may borrow from its lenders. All advances made to professional
associations are guaranteed by the relevant professional association owner,
although there is no independent collateral for these working capital advances.
A repayment default under such advances is also a default under the relevant
management agreement which permits Dental Care Alliance, among other things, to
liquidate the assets of the dental practice. At September 30, 1998, the total
outstanding balance of such advances was $3,015,900. There have been no
revisions to the terms of any such loans or advances. The professional
associations are current in the payment of their loans or advances and Dental
Care Alliance believes that the financial condition of the professional
associations to which it has made loans or advances is satisfactory. Prior to
making any loan or advance, Dental Care Alliance analyzes the collectibility of
the receivables resulting from such loans or advances based on the projected
cash flow of the relevant professional association and the estimated fair market
value of the assets to be owned or owned by such professional association.
Dental Care Alliance, through its obligations under the management agreements,
is able to assess on a periodic basis the collectibility of its receivables
since it has access to the billing and collection information relating to the
professional associations' patient receivables and operational cash flow, and
evaluate on a periodic basis outstanding receivables versus accounts payable and
revenue trends. Accordingly, Dental Care Alliance is in a position to quickly
assess the ability of each professional association to meet its obligations
under the notes and advances. As a result, Dental Care Alliance is able to react
quickly in the event that there is a material change in the creditworthiness of
any of the professional associations. Dental Care Alliance also analyzes any
historical trends of the professional
    
 
                                       89
<PAGE>
   
associations relating to bad debts or the inability of the professional
associations to generate collectible patient receivables. Dental Care Alliance
assesses the guaranty of its professional association owners for financial
stability and creditworthiness through periodic reviews which include analysis
of credit reports, bank references, personal and business tax returns and
personal financial statements. In addition, the reputation of each professional
association owner in the business community and the length and quality of the
professional associations' relationship with Dental Care Alliance are examined
by Dental Care Alliance to assess the professional association owners as
guarantors of the loans and advances. Dental Care Alliance may modify the terms
of management agreements prospectively if the professional association does not
perform at a level sufficient to repay the advances.
    
 
   
    None of the professional association owners are officers, directors or
employees of Dental Care Alliance. Dr. Dennis A. Corona and Dr. Morris Socoloff,
the owners of professional associations operating a majority of the managed
dental centers, own collectively approximately one percent of Dental Care
Alliance common stock. In addition, five managed dental centers in Michigan are
owned by professional associations commonly controlled by Dr. Ross Johnson.
    
 
   
    The professional associations are primarily liable for repayment of the
notes and advances to Dental Care Alliance with the professional association
owners being secondarily liable for repayment under the notes and advances. The
professional associations and professional association owners bear the primary
risk under the notes and advances. Dental Care Alliance also bears the risk of
non-payment to the extent that the assets of professional associations or
professional association owners are insufficient to pay the outstanding balances
under the notes or advances upon any default.
    
 
   
    The professional associations take reserves against, and, when appropriate,
write-off bad debts on, patient receivables. To date, there have been no
defaults under, or write-offs in connection with, notes receivable from or
advances to professional associations, although there can be no assurance that
there will be no such defaults or write-offs in the future. Although there has
to date been no default or material delinquency under the notes or advances,
Dental Care Alliance has established a reserve for such defaults in the amount
of $120,000 as of September 30, 1998. Dental Care Alliance will consider
establishing reserves against such defaults should future circumstances
demonstrate the need for such reserves.
    
 
   
    The management agreements for professional associations that have
acquisition loans from Dental Care Alliance and for most professional
associations with working capital advances provide that the professional
associations must meet their repayment obligations under any outstanding
indebtedness, whether owed to Dental Care Alliance or any third party, prior to
paying any management fees. A default under any such obligation is by its terms
a default under the management agreement. In the event of such a default, Dental
Care Alliance or its designee is entitled to purchase the assets and liabilities
or the capital stock of the relevant professional association at a price equal
to 60% of the annualized gross revenues of such professional association owner
over the previous 24 months, minus any liabilities, including outstanding
indebtedness, if any, to Dental Care Alliance of the professional association at
the date of purchase. In such event, Dental Care Alliance would evaluate
whether, at its option, to have another professional association owner or other
licensed dentist assume control of the practice and continue to generate
management fees or to liquidate the assets of such professional association.
    
 
   
    Dental Care Alliance does not consolidate the balance sheets or the
operating results (including revenue and expenses) of the dental practices under
the management agreements since these revenues and expenses are earned and
incurred by the professional associations, not Dental Care Alliance. Dental Care
Alliance has recorded goodwill and other intangible assets in cases where Dental
Care Alliance has paid a professional association in consideration for a
modification to an existing management agreement or entering into new management
agreements. Where Dental Care Alliance acquires the assets of another management
company, such a transaction constitutes a business combination and Dental Care
Alliance recognizes the related goodwill, if any, in accordance with the
purchase method of accounting.

    Prior to October 1996, the majority of Dental Care Alliance's operations
were performed through limited liability companies. Except for the period from
January through September 1994 with respect to one of Dental Care Alliance's
predecessors in interest, Dental Care Alliance's statements of operations prior
to October 1996 do not include a provision for income taxes. Included in Dental
Care Alliance's tax accruals are amounts related to establishing a deferred tax
liability for book/tax differences arising from its reorganization from limited
liability corporation to C corporation status.
 
   
    In October 1997, Dental Care Alliance expanded its management information
system hardware and software in the corporate office. In 1998, Dental Care
Alliance has begun testing of new dental practice management software in several
of its managed dental centers. It is anticipated that all of the dental
practices currently under management will have installed the new software and,
where necessary, upgraded its hardware requirements. Dental Care Alliance
believes that the cost for the hardware and software will not be in excess of
$500,000. The new software installed at several of the managed dental centers
and the corporate offices have addressed the Year 2000 issues for those systems
under Dental Care Alliance's control. Dental Care Alliance has not determined
the level of preparedness of third parties with which it deals nor the
implications that a failure on their part could have on Dental Care Alliance.
Dental Care Alliance is in the process of making that determination. In
analyzing potential new affiliations, Dental Care Alliance will consider the
cost and timing of a practice's ability to meet the Year 2000 issue before
executing an agreement.
    
 
ACQUISITIONS
 
   
    On December 29, 1997, Dental Care Alliance acquired all of the outstanding
capital stock of Marketplace Dental, Inc. pursuant to the merger of Marketplace
Dental with and into Dental Care Alliance of Florida, Inc., a wholly-owned
subsidiary of Dental Care Alliance. This transaction has been recorded under the
purchase method of accounting.
    
 
   
    Pursuant to the merger, Dental Care Alliance acquired all of the assets of
Marketplace Dental. All shares of Marketplace Dental common stock were converted
into the right to receive, in the aggregate, 80,000 shares of common stock of
Dental Care Alliance and an amount in cash of approximately $500,000. In
addition, the merger agreement calls for the issuance of additional common stock
if certain operating results are achieved. Marketplace Dental is a dental
practice management company which manages six dental practices in Palm Beach
County, Florida. The assets consisted primarily of non-dental assets (including
dental equipment) and management agreements.
    
 
   
    The effective date specified in the merger agreement was December 1, 1997,
based upon the assumption of defined net assets per the final November 30, 1997
balance sheet. Since the articles of merger were not executed and accepted by
the State of Florida until December 29, 1997, Dental Care Alliance's statement
of operations excludes the revenue and expenses of Marketplace Dental for the
period from December 1, 1997 until December 29, 1997. Had the effective date
been December 1, 1997 as specified in the merger agreement, Dental Care
Alliance's revenues and managed dental center expenses for the year ended
December 31, 1997 would have been as follows (unaudited):

    On April 1, 1998, Dental Care Alliance acquired all the outstanding capital
stock of Dental One Associates, Inc. pursuant to a stock purchase agreement
effective March 20, 1998. The assets of Dental One Associates, Inc. consisted
primarily of non-dental assets (including dental equipment) and management
agreements.
 
   
    The purchase price was (a) $2,400,000 in cash; (b) a promissory note in the
amount of $1,470,510, bearing an annual interest rate equal to 8.5%, payable in
equal quarterly installments of principal and
    
 
                                       91

interest amortized over a period of five years with a balloon payment for the
remaining principal balance and accrued interest on the third anniversary; and
(c) a promissory note in the amount of $1,200,000, payable in equal monthly
installments over a period of 120 days.
 
RESULTS OF OPERATIONS
 
   
NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO THE NINE MONTHS ENDED SEPTEMBER
  30, 1997
    
 
   
    MANAGEMENT FEES.  Management fees increased 319.5% from $4.7 million for the
nine months ended September 30, 1997 to $19.7 million for the nine months ended
September 30, 1998. Revenues at existing practices grew ten percent to
approximately $2.8 million, while the balance of the increase relates to the
addition of 43 managed dental centers since January 1, 1997.
    
 
   
    CONSULTING AND LICENSING FEES.  Consulting and licensing fees increased 115%
from $216,284 for the nine months ended September 30, 1997 to $465,315 for the
nine months ended September 30, 1998. The increase is attributable to the
addition of 43 managed dental centers, offset by the cessation of approximately
$85,000 on four Michigan practices which were converted effective July 1, 1997
into managed dental centers. Income from consulting fees is now included in
management fees.
    
 
   
    MANAGED DENTAL CENTER EXPENSES.  Managed dental center expenses increased
from $3.8 million for the nine months ended September 30, 1997 to $13.3 million
for the nine months ended September 30, 1998. As a percentage of net patient
revenue at managed dental centers, managed dental center expenses decreased from
56% to 48%. The decrease is due to economies in purchasing of dental supplies
and laboratories (2%), reduced marketing expenditures (1%) in new affiliations
with established reputations and other general and administrative expenses (4%).
    
 
   
    SALARIES AND BENEFITS.  Salaries and benefits increased 119% from $557,528
for the nine months ended September 30, 1997 to $1.2 million for the nine months
ended September 30, 1998. This increase is attributable primarily to the hiring
of additional personnel in Dental Care Alliance's accounting and business
development departments and regional offices in Michigan, Georgia and Palm
Beach, Florida to administer the additional 43 managed dental centers. As a
percentage of net patient revenue, salaries and benefits decreased from 8% to
5%.
    
 
   
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
321% from $313,054 for the nine months ended September 30, 1997 to $1.3 million
for the nine months ended September 30, 1998. This increase is attributable
primarily to opening of regional offices, additional professional costs
associated with the change from a privately-held to publicly-held company and
increased occupancy and travel costs associated with the additional 43 managed
dental centers. As a percentage of the net patient revenue, general and
administrative was 5% for both periods.
    
 
   
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense
increased 703% from $87,062 for the nine months ended September 30, 1997 to
$698,827 for the nine months ended September 30, 1998. This increase is
attributable to the depreciation on the acquired non-dental assets and
amortization on the management agreements obtained in connection with the 43
additional managed dental centers. As a percentage of net patient revenue,
depreciation and amortization increased from 1% to 3%.
    
 
   
    INTEREST INCOME, NET.  Interest income, net increased from $45,809 for the
nine months ended September 30, 1997 to $392,955 for the six months ended June
30, 1998. This increase is attributable primarily to earnings on the higher cash
balance associated with Dental Care Alliance's public offering in November 1997.

<PAGE>
YEAR ENDED DECEMBER 31, 1997 COMPARED TO THE YEAR ENDED DECEMBER 31, 1996
 
   
    MANAGEMENT FEES.  Management fees consist of a percentage of the net
realizable patient-related revenue at the majority of the PAs and a percentage
of the net realizable profits earned by the remaining professional associations.
Management fees increased 488% from $1.3 million for the year ended December 31,
1996, to $7.6 million for the year ended December 31, 1997. Of this increase,
$3.1 million is derived from the addition of seventeen managed dental centers
during the year, while the balance primarily relates to the October 1996
revision to the management agreements. Prior to October 1996, Dental Care
Alliance was not responsible for any managed dental center expenses.
    
 
   
    CONSULTING AND LICENSING FEES.  Consulting and licensing fees consist of
fees earned by Dental Care Alliance for licensing services to all of the dental
centers and consulting services to four managed dental centers in Michigan.
Consulting and licensing fees decreased 16.3% from $347,600 for the year ended
December 31, 1996, to $290,885 for the year ended December 31, 1997. The
decrease is attributable to the cessation of consulting fees on four Michigan
practices which were converted effective July 1, 1997 into managed dental
centers, as income formerly attributable to these consulting fees are now
included in the management fees, offset by the addition of seventeen managed
dental centers in 1997.
    
 
   
    MANAGED DENTAL CENTER EXPENSES.  Managed dental center expenses consist of
non-professional expenses at the managed dental centers. Managed dental center
expenses increased 879% from $603,138 for the year ended December 31, 1996, to
$5.9 million for the year ended December 31, 1997. Of this increase, $2.3
million is derived from the addition of seventeen managed dental centers, while
the balance relates to the October 1996 revision to the management agreements.
Prior to October 1996, Dental Care Alliance was not responsible for any managed
dental center expenses.
    
 
   
    SALARIES AND BENEFITS.  Salaries and benefits consist of costs for salaries
and benefits for employees at Dental Care Alliance's corporate and regional
offices. Salaries and benefits increased 50.8% from $521,683 for the year ended
December 31, 1996, to $786,795 for the year ended December 31, 1997. This
increase was attributable primarily to the hiring of additional personnel in
Dental Care Alliance's accounting and business development departments to
administer the additional seventeen managed dental centers.
    
 
   
    GENERAL AND ADMINISTRATIVE EXPENSE.  General and administrative expenses
consists of expenses related to the operation of Dental Care Alliance's
corporate and regional offices, such as rent, legal, accounting and travel
expenses. General and administrative expense increased 130.5% from $260,558 for
the year ended December 31, 1996, to $600,657 for the year ended December 31,
1997. This increase was primarily attributable to the establishment of a
regional office in Michigan, increased legal, insurance and other costs required
of a public company, and increased costs associated with expanding Dental Care
Alliance's corporate office to administer the additional seventeen managed
dental centers.
    
 
   
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense
consists of the depreciation expense on capital assets owned by Dental Care
Alliance and located at either the corporate offices or at managed dental
centers and amortization expense on management agreements or other intangible
assets. Depreciation and amortization expense increased 491.9% from $27,654 for
the year ended December 31, 1996, to $163,681 for the year ended December 31,
1997. This increase was attributable to the depreciation on the acquired
non-dental assets and amortization on the acquired management agreements related
to the seventeen additional managed dental centers, as well as a full year's
amortization on the management agreements capitalized in October 1996.
    
 
    INTEREST INCOME, NET.  Interest income, net increased 1168.3% from $20,781
income for the year ended December 31, 1996, to $263,568 income for the year
ended December 31, 1997. This increase was attributable primarily to earnings on
cash balances associated with Dental Care Alliance's public offering in November
1997.

<PAGE>
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
    MANAGEMENT FEES.  Management fees increased 151.1% from $513,705 in 1995 to
$1.3 million in 1996. This increase resulted primarily from the October 1996
revision to the management agreements and, to a significantly lesser extent, the
execution of four new management agreements.
 
   
    CONSULTING AND LICENSING FEES.  Consulting and licensing fees increased
32.3% from $262,769 in 1995 to $347,600 in 1996. This increase was attributable
primarily to an increase in the consulting fees earned from the Michigan
practices, additional license fees earned from four new managed dental centers
and a full year of license fees from four managed dental centers acquired in
1995.
    
 
    MANAGED DENTAL CENTER EXPENSES.  Managed dental center expenses increased
from $0 in 1995 to $603,138 in 1996. This increase was attributable to the
revisions to the management agreements in October 1996. Prior to 1996, Dental
Care Alliance was not responsible for any managed dental center expenses.
 
   
    SALARIES AND BENEFITS.  Salaries and benefits increased 30.2% from $400,669
in 1995 to $521,683 in 1996. This increase was attributable primarily to the
hiring of additional staff at four new managed dental centers.
    
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expense increased
11.1% from $234,577 in 1995 to $260,558 in 1996. This increase was attributable
to increased expense associated with the revised management agreements and the
cost of incorporating and recapitalizing Dental Care Alliance.
 
    ADVISORY SERVICES.  Advisory services expense relates to non-cash charges
for warrants issued in consideration of certain advisory services rendered to
Dental Care Alliance by a third party. Advisory services expense decreased from
$127,768 in 1995 to $0 in 1996 as a result of a one time recognition in 1995 of
such expense.
 
   
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense
increased 25.1% from $22,106 in 1995 to $27,654 in 1996. This increase was
attributable to depreciation of additional equipment, amortization of
incorporation costs and amortization of management agreements capitalized in
October 1996 in connection with the revision of the management agreements.
    
   
    INTEREST INCOME, NET.  Interest income, net increased 220.0% from $6,494 in
1995 to $20,781 in 1996. This increase was attributable primarily to earnings on
increased cash balances and earnings on notes receivable from managed dental
centers.
    
 
SEASONALITY
 
   
    Dental Care Alliance historically has experienced seasonal fluctuations in
its quarterly revenue. Specifically, the first and fourth quarters reflect the
highest patient volume, while the third quarter has traditionally had the lowest
patient volume. The managed dental centers in Florida have traditionally
experienced increased patient visits in November through March due to an
increase in the population base during these months, while patient visits
decrease during the summer. Dental Care Alliance began managing additional
managed dental centers in Michigan and Georgia in July 1997 and March 1998,
respectively, and has recently commenced management of additional managed dental
centers in Indiana. Dental Care Alliance expects that the seasonality in Florida
will be offset to some extent by fewer seasonal fluctuations in Michigan,
Georgia and Indiana.

LIQUIDITY AND CAPITAL RESOURCES
    
 
   
    Since its inception and until Dental Care Alliance's public offering on
November 4, 1997, Dental Care Alliance financed its operations primarily through
internal cash flow, the sale of equity securities and commercial bank
borrowings. Net cash provided by operations for the years ended December 31,
1995, 1996 and 1997 and the nine months ended September 30, 1998 was $75,873,
$270,121 $557,767 and $718,050, respectively. Net cash provided by operating
activities for the years ended December 31, 1995, 1996 and 1997 and the nine
months ended September 30, 1998 consisted primarily of net income, adjusted for
non-cash expenses, and increases in accounts payable and accrued liabilities,
offset by increases in consulting and license fee receivables and management
fees receivable.
    
 
   
    Cash used in investing activities for the years ended December 31, 1995,
1996 and 1997 and the nine months ended September 30, 1998 was ($5,649),
($487,858), ($2.0 million) and ($13.1 million), respectively. For the year ended
December 31, 1995, payments on notes receivable offset a $20,000 increase in
other assets. For the year ended December 31, 1996, the investing activities
were primarily related to organizational costs associated with the formation of
Dental Care Alliance in October 1996 through a reorganization of its predecessor
entities. For the year ended December 31, 1997, the investing activities
included $1.0 million related primarily to the purchase of management agreements
for the four Michigan managed dental centers and $613,006 related primarily to
the purchase of non-dental assets for three additional managed dental centers
and certain equipment purchases for the corporate office expansion. For the nine
months ended September 30, 1998, the investing activities included $9.3 million
related primarily to the purchase of management agreements, $2.9 million related
to the purchase of non-dental assets, $468,487 related to satisfaction of
outstanding obligations on acquisitions and affiliations and $450,000 related to
an increase in notes receivable to professional associations.
    
 
   
    Cash (used in) provided by financing activities for the and the years ended
December 31, 1995, 1996 and 1997 and the nine months ended September 30, 1998
was ($69,926), $1,428,803, $20,572,424 and ($352,543), respectively. In the year
ended December 31, 1995, the financing activities included $45,692 in debt
repayments and $40,000 in dividends on Dental Care Alliance's preferred stock.
For the years ended December 31, 1996, the financing activities were primarily
related to net proceeds on Dental Care Alliance's issuance of preferred stock.
For the year ended December 31, 1997, Dental Care Alliance had $21.2 million in
net proceeds on common stock issuances offset by $466,967 in advances to
professional associations and $167,945 in net repayment of debt. For the nine
months ended September 30, 1998 Dental Care Alliance had $2.3 million in net
proceeds on long-term debt offset by $2.5 million in working capital advances to
professional associations.
    
 
   
    In August 1997, Dental Care Alliance entered into a revolving line of credit
which provides for an aggregate of $1.2 million. Under the terms of the credit
agreement, Dental Care Alliance may use up to
    
 
                                       95
<PAGE>
   
$600,000 of the credit line for the purchase of non-dental assets of dental
centers provided that each borrowing is repaid within 45 days of its drawdown.
The remaining $600,000 may be used for general working capital needs. The
revolving line of credit bears interest at 0.75% per annum above the lender's
prime rate and is payable on demand. Interest only is payable monthly. Amounts
borrowed pursuant to the credit agreement are secured by a first security
interest in most of Dental Care Alliance's assets, including receivables and
equipment. Additionally, any outstanding balances under the working capital line
are guaranteed by Dr. Matzkin.
    
 
   
    On May 14, 1998, Dental Care Alliance executed a $15 million revolving note
with NationsBank, N.A. which replaced the credit agreement. The revolving note
is intended to provide funds for the acquisition and affiliation with dental
practices and working capital uses in a revolving line of credit facility. The
note matures in one year, with annual renewals thereafter. Dental Care Alliance,
and its subsidiaries, have pledged substantially all of its assets as
collateral. The note bears interest at 1.75% over LIBOR, payable monthly. Dental
Care Alliance is required to maintain certain financial covenants during the
term of the note. As of September 30, 1998, Dental Care Alliance had $1.0
million outstanding against the revolving note.
    
 
   
    Dental Care Alliance previously has made loans to various professional
associations in connection with the professional associations' acquisition of
assets of dental practices and has made working capital advances to various
professional associations for their operations. The loans, which are evidenced
by interest-bearing notes that are payable upon demand, are being paid in
accordance with their terms. Both the loans and advances are generally
personally guaranteed by the professional association owners or secured by
specific assets.
    
 
   
    Dental Care Alliance intends to enter into additional management agreements
with respect to, as well as purchase the non-dental assets of, additional
practices. In addition, Dental Care Alliance intends to acquire management
agreements or lend money to professional associations to fund the purchase of
the assets of additional dental practices. Dental Care Alliance plans to finance
these activities through a combination of the available cash, cash flow from
operations, bank financing and issuances of Dental Care Alliance common stock.
    
 
   
    On November 4, 1997, Dental Care Alliance completed the public offering of
2,000,000 shares of Dental Care Alliance common stock at $12 per share resulting
in proceeds, net of underwriter commissions and offering costs, of approximately
$21.2 million. Based upon Dental Care Alliance's anticipated needs for
acquisition of non-dental assets of dental practices, working capital and
general corporate purposes, management believes that the combination of existing
cash, cash flow from operations, available credit lines and net proceeds from
its initial public offering will be sufficient to meet its capital requirements
for the next 12 months.
    
 
INFLATION
 
    Inflation has not had a significant impact on Dental Care Alliance in the
past nor is it expected to have a significant impact in the foreseeable future.
 
   
YEAR 2000 COMPLIANCE
    
 
   
    Dental Care Alliance has taken certain measures intended to avoid Year 2000
problems. In evaluating the Year 2000 readiness of its information technology
systems, Dental Care Alliance has taken certain preventive measures. In November
1997, Dental Care Alliance installed a new back-end (corporate office)
information technology system specifically designed to avoid Year 2000 concerns.
Dental Care Alliance continues to update and enhance this system with Year 2000
- -compliant software. The front-end (dental office) information technology
systems vary from office to office, and many of such systems are not Year 2000
compliant. Dental Care Alliance intends to take advantage of Gentle Dental's
in-house
    
 
                                       96
<PAGE>
   
management information systems staff to resolve these front-end deficiencies. In
addition, it is expected that the new company will integrate an entirely new
front-end package to deal with these deficiencies.
    
 
   
    There are also potential Year 2000 problems associated with non-information
technology systems of certain entities with whom Dental Care Alliance conducts
business-related activities: its banks, a co-employer and entities from whom
Dental Care Alliance receives reimbursements, such as insurance companies and
state agencies. The banks and the co-employer have indicated that they have
taken or will take steps to ensure that their systems are Year 2000 compliant.
Dental Care Alliance does not believe that failure of these parties successfully
to rectify Year 2000 problems will materially adversely affect its business,
except to the extent that third party reimbursements are delayed as a result of
Year 2000 problems.
    
 
   
    Dental Care Alliance estimates its cost of Year 2000 compliance will
aggregate approximately $500,000.
    
 
   
    The most reasonably likely worst case scenario for Dental Care Alliance
resulting from Year 2000 issues are as follows: billing and cash collection will
be delayed if Dental Care Alliance is unable to deliver information
technology-based billings to patients and receive information technology-based
reimbursements from third parties. If Year 2000 problems were to effect Dental
Care Alliance's front-end systems, it would be necessary to bill patients based
upon manual calculation, which could delay cash flows for up to several months.
If this problem were to occur, Dental Care Alliance would attempt to collect
payments from patients at the time of service.
    
 
   
    Dental Care Alliance has outlined a contingency plan to deal with potential
Year 2000 problems. First, it has obtained an alternative Year 2000 compliant
front-end system, now being tested, in the event there are unforeseen problems
with installing the front-end system currently utilized by Gentle Dental. In
addition, Dental Care Alliance is maintaining some availability under its loan
agreement in anticipation of any cash flow shortages resulting from Year 2000
problems.

OPTION GRANTS
 
   
    The following table sets forth certain information with respect to options
to purchase shares of Dental Care Alliance common stock granted to the executive
officers identified in the table during 1997 and represents all options granted
by Dental Care Alliance to such executive officers during such period. In
accordance with rules promulgated by the Securities and Exchange Commission, the
table also describes the hypothetical gains that would exist for the respective
options based on assumed rates of annual compound stock appreciation of 5% and
10% from the date of grant to the end of the option term. These hypothetical
gains are based on assumed rates of appreciation and, therefore, the actual
gains, if any, on stock option exercises are dependent on the future performance
of Dental Care Alliance common stock, overall stock market conditions, and the
executive officer's continued employment with Dental Care Alliance. As a result,
the amounts reflected in this table may not necessarily be achieved.

EMPLOYMENT AGREEMENTS
 
    Dental Care Alliance has entered into employment agreements with Dr. Steven
R. Matzkin, Chairman of the Board, Chief Executive Officer and President of
Dental Care Alliance, Mitchell B. Olan, Vice President and Chief Operating
Officer of Dental Care Alliance, and David P. Nichols, Chief Financial Officer
of Dental Care Alliance. The employment agreements of Messrs. Matzkin and Olan
were entered into as of October 25, 1996, and are for terms of five years and
four years, respectively. The employment agreement of Mr. Nichols was entered
into as of January 1997 and is for a term of four years. These agreements
provide for annual base salaries to Messrs. Matzkin, Olan and Nichols of
$200,000, $120,000 and $120,000, respectively, subject to increase at Dental
Care Alliance's discretion. Pursuant to the agreements, Dr. Matzkin and Messrs.
Olan and Nichols are entitled to receive 60%, 25% and 15%, respectively, of an
annual bonus pool which is equal to 50% of Dental Care Alliance's net income in
excess of Dental Care Alliance's budgeted net income for each year. Bonuses paid
to Dr. Matzkin, Mr. Olan and Mr. Nichols in any year may not exceed $200,000,
$100,000, and $50,000, respectively. Dr. Matzkin's, Mr. Olan's and Mr. Nichols'
employment agreements entitle them to participate in any stock option plan of
Dental Care Alliance at a level commensurate with their positions. Mr. Olan's
employment agreement entitled him to warrants to purchase 163,080 shares of
common stock for an aggregate exercise price of $272,768. These warrants were
exercised in February 1997. Upon Dental Care Alliance's constructive discharge
of Dr. Matzkin or termination of the employment of Dr. Matzkin without cause, as
specified in his employment agreement, Dr. Matzkin shall be entitled to receive
his base salary for the period commencing on the effective date of the
termination and ending on the later to occur of (x) the second anniversary of
the date of termination or (y) the end of the five-year term of the employment
agreement. Upon Dental Care Alliance's termination of Mr. Olan without cause, as
specified in his employment agreement, Mr. Olan shall be entitled to receive his
base salary for the period commencing on the date of termination and ending on
the date nine months thereafter. Upon Dental Care Alliance's termination of Mr.
Nichols without cause as specified in his employment agreement, Mr. Nichols
shall be entitled to receive his base salary for the period commencing on the
date of termination and ending on the date six months thereafter. Upon
termination with cause or voluntary termination of either Dr. Matzkin, Mr. Olan
 
                                      101
<PAGE>
or Mr. Nichols, such executive shall be entitled to receive his base salary
through the effective date of such termination.
 
   
    Dr. Matzkin's employment agreement also provides that upon termination of
his employment for any reason, if Dental Care Alliance's securities are then
publicly traded, Dr. Matzkin has the right to request that Dental Care Alliance
register, as expeditiously as possible, any or all of Dental Care Alliance
common stock then owned by Dr. Matzkin, including all shares of Dental Care
Alliance common stock issuable pursuant to any derivative securities of Dental
Care Alliance then held by Dr. Matzkin.
    
 
   
    The parties anticipate that upon consummation of the mergers, Dr. Matzkin
will enter into a three-year employment agreement with Wisdom Holdings, pursuant
to which Dr. Matzkin shall
    
 
   
    - hold the offices of Co-Chairman, President and Chief Dental Officer of
      Wisdom Holdings;
    
 
   
    - receive a base salary of $245,000 per annum and shall be entitled to
      participate in bonus, benefit and stock option plans generally available
      to other senior executive officers of the combined company;
    
 
   
    - receive an automobile allowance of $1,000 per month;
    
 
   
    - be subject to covenants prohibiting disclosure of confidential information
      of Wisdom Holdings and competition with, or solicitation of employees of,
      Wisdom Holdings; and
    
 
   
    - be entitled to severance payments for a period of 36 months if he is
      terminated without cause or if he terminates his employment for good
      reason.
    
 
CERTAIN TRANSACTIONS REGARDING DENTAL CARE ALLIANCE
 
   
    In 1993, Dr. Matzkin sold four dental practices in Michigan to Dr. David
Ross Johnson, a dental director, for a $237,000 note under which payments
commenced in May 1997. In connection with that sale Profit Dental Management,
Inc., a corporation controlled by Dr. Matzkin, agreed to provide consulting
services to these practices for $18,000 per month until May 1997 and $15,000 per
month thereafter through May 2005. In July 1997, Dental Care Alliance purchased
the right to manage these practices for $846,000 and entered into a global
management agreement pursuant to which it will provide management services to
these practices until 2005. Dental Care Alliance subcontracted the day-to-day
management services to an affiliate of Dr. Johnson, but retains most other
management functions for which it retains 20% of net profits of these practices,
after certain adjustments, and Dr. Johnson's affiliate is paid 80% of such net
profits. Dental Care Alliance also receives $800 per month from each practice as
a licensing fee.
    
 
   
    In July 1997, Dental Care Alliance entered into a management agreement with
a professional association in Michigan which was controlled by Dr. Matzkin. As
of September 30, 1997, Dr. Matzkin assigned the ownership of the capital stock
and all rights relating thereto to Dr. David Ross Johnson in consideration for
Dr. Johnson's assumption of all obligations to pay for such capital stock and
all obligations relating to such capital stock.
    
 
   
    Certain of the managed dental centers lease their office facilities from
entities controlled by Dr. Matzkin. Such leases terminate at various times
between 2000 and 2004. Managed dental centers and Dental Care Alliance paid rent
pursuant to the leases in the aggregate amount of $193,900 in 1997 and have paid
$111,000 from January 1, 1998 through September 30, 1998. Dr. Matzkin also owns
certain dental laboratories that perform laboratory services for the managed
dental centers, primarily relating to the making of prostheses. In 1997 the
amount paid by the managed dental centers to such laboratories was $133,448 of
which $60,000 was advanced by Dental Care Alliance in 1996 and remains
outstanding at September 30, 1998, while the amount paid from January 1, 1998
through September 30, 1998 was $120,606. Dr. Matzkin owns 33.3% of the capital
stock of Equipment Management Services, an equipment leasing company. Certain
managed dental centers have entered into capitalized equipment leases with
    
 
                                      102
<PAGE>
   
Equipment Management Services. Amounts paid by such managed dental centers to
Equipment Management Services pursuant to such leases aggregated approximately
$123,000 in 1997 and $20,000 from January 1, 1998 through September 30, 1998.
Dental Care Alliance believes that such arrangements are no less favorable to
such managed dental centers than could have been obtained in arms-length
transactions with unrelated third parties. In addition, Dr. Matzkin has
personally guaranteed an aggregate of approximately $1.6 million of indebtedness
of certain of the managed dental centers. Dental Care Alliance is currently
negotiating with the lenders to whom Dr. Matzkin has given such guarantees to
release Dr. Matzkin from his obligations thereunder and to cause Dental Care
Alliance to guaranty such obligations.
    
 
   
    Pursuant to a Stockholders' Agreement among Dental Care Alliance and Dr.
Matzkin, Mr. Smith, Mr. Raucci, the SRM 1993 Children's Trust and Crescent
International Holdings, Inc. initially entered into in connection with the sale
of Dental Care Alliance's Series A preferred stock in October 1996, each
stockholder a party thereto received each of the following:
    
 
   
    - "piggyback" registration rights;
    
 
   
    - a right of first refusal with respect to a greater than 50% share transfer
      by a stockholder prior to an initial public offering meeting certain
      conditions;
    
 
   
    - co-sale rights to participate on a pro rata basis in certain resales of
      Dental Care Alliance common stock by other stockholders party to the
      agreement (other than in connection with an initial public offering
      meeting certain conditions; and
    
 
   
    - participation rights with respect to certain issuances of securities by
      Dental Care Alliance made prior to an initial public offering meeting
      certain conditions.
    
 
   
In addition, stockholders party to the agreement who are also directors of
Dental Care Alliance, other than Dr. Matzkin, also were granted demand
registration rights under the Stockholders' Agreement. Mitchell B. Olan has been
granted certain "piggyback" registration rights with respect to an aggregate of
163,080 shares of Dental Care Alliance common stock pursuant to an agreement
with Dental Care Alliance. Pursuant to Dr. Matzkin's employment agreement, upon
termination of his employment for any reason, if Dental Care Alliance's
securities are then publicly traded, Dr. Matzkin has the right to request that
Dental Care Alliance register any or all of Dental Care Alliance common stock
then owned by Dr. Matzkin.
    
 
   
    Upon consummation of the mergers, each affiliate of Wisdom Holdings,
including the above-mentioned stockholders, will receive, with respect to the
shares issued to such affiliates pursuant to the mergers and the shares issuable
upon exercise of options and warrants held by such affiliates, (a) "piggyback"
registration rights, and (b) one demand registration right per calendar year.
Wisdom Holdings will, however, be obligated to effect no more than one demand
registration during any calendar year. Upon a request for a demand registration
by any affiliate, all other affiliates will be entitled to participate in such
registration with all other affiliates electing to participate pro rata on the
basis of the number of registrable shares held by each participating affiliate.
Further, the combined company will not be required to cause a registration under
the above-described demand registration rights unless the aggregate offering
price of all registrable shares to be registered pursuant to such demand
registration rights, before deduction of underwriting discounts and commissions
exceeds $5,000,000.
    
 
   
    For information regarding employment agreements with certain executive
officers and directors, see "--Employment Agreements." Dental Care Alliance has
adopted a policy whereby all transactions between Dental Care Alliance and one
or more of its affiliates must be approved in advance by a majority of Dental
Care Alliance's disinterested directors.

preferred stock, all of which are issued and outstanding; and 2,000,000 shares
of Gentle Dental Series D preferred stock, of which 1,628,664 shares are issued
and outstanding.
    
 
   
    GENTLE DENTAL SERIES A PREFERRED STOCK.  The Gentle Dental Series A
preferred stock ranks senior to the Gentle Dental common stock regarding
liquidation, is equal in preference with the Gentle Dental Series C preferred
stock but junior to all other series of Gentle Dental preferred stock. In the
event of any voluntary or involuntary liquidation, dissolution or winding-up of
the affairs of Gentle Dental, holders of Gentle Dental Series A preferred stock
will be entitled to receive, out of assets legally available for distribution to
shareholders before payment to holders of any outstanding stock with a
liquidation

preference junior to the Gentle Dental Series A preferred stock, an amount equal
to $1.00 per share, subject to adjustment for any recapitalization, subdivision
or recombination. There is no dividend preference for the holders of Gentle
Dental Series A preferred stock. The shares of Gentle Dental Series A preferred
stock have no conversion rights but may be redeemed at the option of Gentle
Dental under certain circumstances and must be redeemed by Gentle Dental under
certain other circumstances, provided Gentle Dental has funds legally available
for such redemption. The holders of outstanding shares of Gentle Dental Series A
preferred stock have the right to elect one member of Gentle Dental's Board of
Directors, which member as of September 30, 1998, was Eric Green. Under certain
circumstances, the holders of Gentle Dental Series A preferred stock will be
entitled to elect one additional individual to the Gentle Dental Board of
Directors.
    
 
   
    GENTLE DENTAL SERIES B PREFERRED STOCK.  Although there presently are no
shares of Gentle Dental Series B preferred stock outstanding, if certain events
of default on Gentle Dental's 7% Convertible Subordinated Notes occur, the
convertible subordinated notes then outstanding will automatically convert into
shares of Gentle Dental Series B preferred stock at a rate of one share of
Gentle Dental Series B preferred stock for each $1,000 in principal and accrued
but unpaid interest on such convertible subordinated notes, subject to
adjustment for any recapitalization, subdivision or recombination. The Gentle
Dental Series B preferred stock ranks senior to all other classes and series of
equity securities of the corporation presently existing or created in the
future, with respect to dividend rights, rights of redemption, rights of
conversion and liquidation preferences. In the event of a liquidation, holders
of Gentle Dental Series B preferred stock then outstanding will be entitled to
receive, out of assets legally available therefor, an amount per share equal to
the greater of $1,000 or the amount such holder would receive as a holder of
Gentle Dental common stock upon conversion of such holder's Gentle Dental Series
B Preferred into Gentle Dental common stock. The holders of Gentle Dental Series
B preferred stock shall be entitled to receive, when, as and if declared by the
Gentle Dental Board of Directors, a cumulative dividend, which includes the
original cost of a share of Gentle Dental Series B preferred stock of $1,000,
plus an additional amount, which amount varies depending upon, among other
things, (a) whether there exists an event of default under the securities
purchase agreement between Gentle Dental and the holders of Gentle Dental Series
B preferred stock and (b) the interest rate applicable to the convertible
subordinated notes, as determined under such notes, for the dividend period in
question. Upon the occurrence of certain events, Gentle Dental is required to
redeem the outstanding shares of Gentle Dental Series B preferred stock at an
amount per share equal to the greater of $1,000, subject to adjustment for any
recapitalization, subdivision or recombination, or the fair value of such shares
determined in good faith by Gentle Dental and the holders thereof. The holders
of a majority of the outstanding shares of Gentle Dental Series B preferred
stock may elect to have Gentle Dental redeem all such shares any time on or
after the occurrence of an event of default under the securities purchase
agreement between Gentle Dental and the holders of Gentle Dental Series B
preferred stock. The redemption price per share is $1,000, plus accumulated but
unpaid dividends, provided there has not been a change in control. If there is a
change in control of Gentle Dental, the redemption price is equal to $1,010 per
share, plus accumulated but unpaid dividends. In any case, the redemption price
is subject to adjustment for any recapitalization, subdivision or recombination.
Gentle Dental may elect to redeem all or any portion of any Gentle Dental Series
B preferred stock outstanding at a per share price of $1,000, plus any accrued
but unpaid dividends. The holders of such redeemed shares shall be entitled to
receive a warrant initially exercisable for that number of shares of such Gentle
Dental common stock, including accrued and unpaid dividends thereon, into which
such redeemed shares would have been convertible in the event of an optional
conversion by the holders thereof. In the event of a change in control of Gentle
Dental, the redemption price applicable to a company-elected redemption shall be
increased by $10 per share, subject to adjustment for any recapitalization,
subdivision or recombination.
    
 
   
    Each holder of shares of Gentle Dental Series B preferred stock may, at such
holder's option and at any time, convert any such share, or the accumulated but
unpaid dividends thereon, into 108.58 shares of Gentle Dental common stock,
subject to certain priced-based and other anti-dilution adjustments. In
    
 
                                      107
<PAGE>
   
addition, upon the occurrence of certain events and the giving of notice and the
passage of an applicable time period, all shares of Gentle Dental Series B
preferred stock then outstanding shall be deemed automatically converted into
shares of Gentle Dental common stock; provided, such Gentle Dental common stock
is then listed on a national securities exchange or reported by the Nasdaq
National Market and is either registered under the Securities Act or freely
tradable under Rule 144 of the Securities Act within six months of the date of
issuance. In addition to the rights provided under the Washington Business
Corporation Act, holders of Gentle Dental Series B preferred stock are entitled
to vote on all matters, holders of Gentle Dental common stock are entitled to
vote on, together with the common stockholders as a single class. Each share of
Gentle Dental Series B preferred stock shall entitle its holder to the number of
votes the holder would be entitled to as a holder of Gentle Dental common stock
had such holder converted that share of Gentle Dental Series B preferred stock
into shares of Gentle Dental common stock.
    
 
   
    GENTLE DENTAL SERIES C PREFERRED STOCK.  The Gentle Dental Series C
preferred stock ranks senior to the Gentle Dental common stock, equal to the
Gentle Dental Series A preferred stock and junior to all other classes and
series of equity securities of Gentle Dental presently existing or created in
the future, with respect to rights of redemption and liquidation. In the event
of any voluntary or involuntary liquidation, dissolution or winding-up of the
affairs of Gentle Dental, holders of Gentle Dental Series C preferred stock will
be entitled to receive, out of assets legally available for distribution to
shareholders before payment to holders of any stock with a liquidation
preference junior to the Gentle Dental Series C preferred stock, an amount equal
to $1.00 per share of such Gentle Dental Series C preferred stock, subject to
adjustment in the event of any change in the number and kind of shares of Gentle
Dental Series C preferred stock for any recapitalization, subdivision or
recombination. There is no dividend preference for the holders of Gentle Dental
Series C preferred stock. The shares of Series C preferred stock have no
conversion rights. Upon the occurrence of certain events, the holders of
outstanding shares of Gentle Dental Series C preferred stock shall be entitled
to elect one member of the Gentle Dental Board of Directors. The holders of the
Gentle Dental Series C preferred stock generally are not entitled to a
shareholder's vote, except for a vote required under the Washington Business
Corporation Act or under the Gentle Dental Articles of Incorporation. The
holders of Gentle Dental Series C preferred stock are entitled to a separate
vote on the mergers. The shares of Gentle Dental Series C preferred stock must
be redeemed under certain circumstances at a price per share of $1.00, subject
to adjustment for any recapitalization, subdivision or recombination and subject
to Gentle Dental having funds legally available for such redemption.
    
 
   
    GENTLE DENTAL SERIES D PREFERRED STOCK.  The Gentle Dental Series D
preferred stock ranks senior to all other classes and series of equity
securities of Gentle Dental presently existing or created in the future,
including the Gentle Dental Series A preferred and Series C preferred stocks,
but ranks junior to the Gentle Dental Series B preferred stock, with respect to
dividend rights, rights of redemption, rights of conversion and liquidation
preference. In the event of a liquidation, holders of Gentle Dental Series D
preferred stock then outstanding will be entitled to receive, out of assets
legally available therefore, an amount per share equal to the greater of $9.21
(subject to adjustment for any recapitalization, subdivision or recombination)
or the amount such holder would receive as a holder of Gentle Dental common
stock received by such holder upon conversion of such holder's Gentle Dental
Series D preferred stock.
    
 
   
    The holders of Gentle Dental Series D preferred stock shall be entitled to
receive, when, as and if declared by the Gentle Dental Board of Directors, a
cumulative dividend of $.64 each dividend period, commencing February 17, 1999.
In addition, holders of Gentle Dental Series D preferred stock are also entitled
to participate, on an as converted basis, in any dividends declared and paid on
Gentle Dental common stock. The holders of a majority of the outstanding shares
of Gentle Dental Series D preferred stock may elect to have Gentle Dental redeem
all such shares any time on or after the occurrence of an event of default under
the securities purchase agreement between Gentle Dental and the holders of
Gentle Dental Series D preferred stock. The redemption price per share is $9.21,
plus accumulated but unpaid
    
 
                                      108
<PAGE>
   
dividends, provided there has not been a change in control. If there is a change
in control, the redemption price is equal to $9.30 per share, plus accumulated
but unpaid dividends. In any case, the redemption price is subject to adjustment
for any recapitalization, subdivision or recombination. Gentle Dental may elect
to redeem all or any portion of the Gentle Dental Series D preferred stock
outstanding at a per share price of $9.21, plus accumulated but unpaid
dividends. The holders of such redeemed shares shall be entitled to receive a
warrant initially exercisable for that number of shares of Gentle Dental common
stock into which such redeemed shares would have been converted in the event of
an optional conversion by the holders thereof. In the event of a change in
control of Gentle Dental, the redemption price applicable to a company-elected
redemption shall be increased by $9.30 per share, subject to adjustment for any
recapitalization, subdivision or recombination.
    
 
   
    Each holder of a share of Gentle Dental Series D preferred stock may at any
time and at such holder's option, convert any such share, or the accumulated but
unpaid dividends thereon, into one share of Gentle Dental common stock, subject
to certain price based and other anti-dilution adjustments. In addition, upon
the occurrence of certain events, the giving of notice and the passage of an
applicable time period, all shares of Gentle Dental Series D preferred stock
then outstanding shall be deemed automatically converted into shares of Gentle
Dental common stock; provided, such Gentle Dental common stock is then listed on
a national securities exchange or reported by the Nasdaq National Market and is
either registered under the Securities Act or freely tradable under Rule 144 of
the Securities Act within six months of the date of issuance. In addition to the
rights provided under the Washington Business Corporation Act, the holders of
Gentle Dental Series D preferred stock are entitled to vote on all matters as to
which holders of Gentle Dental common stock are entitled to vote, together with
the common shareholders as a single class. Each share of Gentle Dental Series D
preferred stock shall entitle its holder to the number of votes the holder would
be entitled to as a holder of Gentle Dental common stock had such holder
converted such share of Gentle Dental Series D preferred stock into shares of
Gentle Dental common stock.
    
 
   
    7% CONVERTIBLE SUBORDINATED NOTES.  On May 18, 1998 Gentle Dental issued
$25,500,000 of convertible subordinated notes and on June 3, 1998, Gentle Dental
issued an additional $4,500,000 of convertible subordinated notes. The
convertible subordinated notes have an 8-year term and are convertible into
shares of Gentle Dental common stock at a conversion rate equal to one share of
common stock for each $9.21 of outstanding principal and accrued but unpaid
interest on such convertible subordinated notes. If certain events of default
occur, the convertible subordinated notes then outstanding will automatically
convert into shares of Gentle Dental Series B preferred stock at a rate of one
share of Gentle Dental Series B preferred stock for each $1,000 in principal of,
and accrued but unpaid interest on the convertible subordinated notes, subject
to adjustment for any recapitalization, subdivision or recombination. Under the
securities purchase agreement between Gentle Dental and the holders of the
convertible subordinated notes, the consent of the holders of a majority of the
Gentle Dental common stock equivalents issuable upon conversion of the
convertible subordinated notes, is required for approval of the mergers. In
addition, Chase Venture Capital Associates, one of the holders of the
convertible subordinated notes, or its successors or assigns, must consent to
the mergers.

               DESCRIPTION OF DENTAL CARE ALLIANCE CAPITAL STOCK
    
 
   
DENTAL CARE ALLIANCE COMMON STOCK
    
 
   
    The holders of Dental Care Alliance common stock are entitled to one vote
per share of record on all matters to be voted upon by stockholders and to vote
together as a single class for the election of directors and in respect of other
corporate matters. At a meeting of stockholders at which a quorum is present,
for all matters other than the election of directors, a majority of the votes
cast decides all questions, unless the matter is one upon which a different vote
is required by express provision of law or Dental Care Alliance's Certificate of
Incorporation or By-laws. Directors will be elected by a plurality of the votes
of the shares present at a meeting. There is no cumulative voting with respect
to the election of directors (or any other matter).
    
 
   
    The holders of Dental Care Alliance common stock have no preemptive rights
and have no rights to convert their Dental Care Alliance common stock into any
other securities. Subject to the rights of holders of Dental Care Alliance
preferred stock, if any, in the event of a liquidation, dissolution or winding
up of Dental Care Alliance, holders of Dental Care Alliance common stock are
entitled to participate equally and ratably in all assets remaining after
payment of liabilities and distribution of any preferential amount.
    
 
   
    The holders of Dental Care Alliance common stock are entitled to receive
ratably such dividends as the Dental Care Alliance Board of Directors may
declare out of funds legally available therefor; when and if so declared,
subject to any preference in favor of outstanding shares of preferred stock, if
any. The payment by Dental Care Alliance of dividends, if any, rests within the
discretion of the Board of Directors and will depend upon Dental Care Alliance's
results of operations, financial condition and capital expenditure plans, as
well as other factors considered relevant by the Dental Care Alliance Board of
Directors.
    
 
   
DENTAL CARE ALLIANCE PREFERRED STOCK
    
 
   
    At the effective time of the mergers, no shares of Dental Care Alliance
preferred stock will be outstanding. The Dental Care Alliance Board of
Directors, without further action by the stockholders, is authorized to issue up
to 5 million shares of Dental Care Alliance preferred stock in one or more
series and to fix and determine as to any series all the relative rights and
preferences of shares in such series, including, without limitation, relative
voting, dividend, redemption, liquidation, conversion and other powers,
preferences, rights, qualifications and limitations. The issuance of shares of
Dental Care Alliance preferred stock, or the issuance of rights to purchase such
shares, could be used to discourage an unsolicited acquisition proposal that
some, or a majority, of the Dental Care Alliance stockholders might believe to
be in the best interests of Dental Care Alliance or in which Dental Care
Alliance stockholders might receive a premium for their stock over the then
market price of such stock. In addition, under certain circumstances, the
issuance of Dental Care Alliance preferred stock could adversely affect the
voting power of the holders of Dental Care Alliance common stock.

                     CERTAIN DIFFERENCES BETWEEN WASHINGTON
                          AND DELAWARE CORPORATE LAWS
 
   
    The Washington Business Corporation Act governs the rights of Gentle Dental
shareholders and the Delaware General Corporation Law governs the rights of
Dental Care Alliance stockholders and will govern the rights of Gentle Dental
shareholders and Dental Care Alliance stockholders who will become stockholders
of Wisdom Holdings upon consummation of the merger. The Washington Business
Corporation Act and the Delaware General Corporation Law differ in many
respects, some of which could materially affect the rights of Gentle Dental
shareholders. These differences are discussed below.
    
 
AMENDMENT OF ARTICLES/CERTIFICATES OF INCORPORATION
 
   
    Under the Washington Business Corporation Act, with certain exceptions,
amendments to a corporation's articles of incorporation must be recommended to
the shareholders by the board of directors, unless the board of directors
determines that because a conflict of interest or other special circumstances
exist it should make no recommendation and the board of directors communicates
the reasons for its determination to the shareholders with the amendment.
Amendments to the Gentle Dental Articles of Incorporation, subject to limited
exceptions, must be approved by a majority of the holders of the outstanding
shares of each class or series of capital stock entitled to vote as a separate
voting group, unless another proportion is specified in the Gentle Dental
Articles of Incorporation, is specified by the Board of Directors as a condition
to its recommendation of such amendment or is called for by a provision of the
Washington Business Corporation Act. Under the Washington Business Corporation
Act and the Gentle Dental Articles of Incorporation, each separate class or
series of capital stock is entitled to a class vote on certain extraordinary
transactions, such as the merger and related transactions described in the
merger agreement. See "--Class Voting" below.
    
 
   
    Under the Delaware General Corporation Law, amendments to the Dental Care
Alliance and Wisdom Holdings Certificate of Incorporation require the approval
of stockholders holding a majority of the outstanding shares entitled to vote on
such amendment, and if a class vote on such amendment is required by the
Delaware General Corporation Law, a majority of the outstanding stock of each
such class entitled to vote, unless a greater portion is specified in the
Certificate of Incorporation or by a provision of the Delaware Law. Amendments
to the Dental Care Alliance Certificate of Incorporation governing the number,
term and removal of directors and the calling of special meetings of
stockholders must be approved by at least eighty percent of the holders of the
outstanding shares entitled to vote as a single class. The Wisdom Holdings
Certificate of Incorporation will require the affirmative vote of at least a
majority of the outstanding Wisdom Holdings capital stock to approve an
amendment. Also, under the Delaware General Corporation Law and the Wisdom
Holdings Certificate of Incorporation, each separate class or series of capital
stock will be entitled to a class vote on certain extraordinary transactions.
See "-- Class Voting" below.
    
 
   
RIGHT TO CALL SPECIAL MEETING OF STOCKHOLDERS
    
 
   
    The Washington Business Corporation Act provides that a special meeting of
shareholders of a corporation may be called by its board of directors, by
holders of at least 10 percent of all the shares entitled to vote on any issue
proposed to be considered at the proposed special meeting, or by other persons
authorized to do so by the articles of incorporation or bylaws of the
corporation. However, the Washington Business Corporation Act allows the right
of shareholders to call a special meeting to be limited or denied entirely by
provision of the corporation's articles of incorporation. Gentle Dental's Bylaws
provide that its Board of Directors, Chairman of the Board, President, a
majority of the Board of Directors and any shareholder or shareholders holding
in the aggregate one-tenth of the voting power of all shareholders may call a
special meeting.
    
 
   
    Under the Delaware General Corporation Law, a special meeting of
stockholders may be called by the board of directors or by any other person
authorized to do so in the certificate of incorporation or the bylaws. The
Dental Care Alliance Certificate of Incorporation provides that special meetings
may be called
    
 
                                      111
<PAGE>
   
only by the Chairman of the Board of Directors or the Chief Executive Officer or
by the Board of Directors pursuant to a resolution approved by a majority of the
entire Board of Directors. Pursuant to the Wisdom Holdings' Certificate of
Incorporation, only the Wisdom Holdings Board of Directors, an authorized
committee of members of the Board of Directors or any other persons specified in
any amendments to or designations under the Wisdom Holdings' Certificate of
Incorporation may call special meetings of the stockholders.
    
 
INDEMNIFICATION OF OFFICERS, DIRECTORS AND EMPLOYEES
 
   
    Under the Washington Business Corporation Act, if authorized by its articles
of incorporation, a bylaw adopted or ratified by its shareholders generally, or
a resolution adopted or ratified, before or after the event by its shareholders,
a corporation has the power to indemnify a director, officer or employee made a
party to a proceeding, or advance or reimburse expenses incurred in a
proceeding. However, no such indemnification is allowed for any of the
following:
    
 
    - acts or omissions of a director, officer or employee finally adjudged to
      have engaged in intentional misconduct or a knowing violation of the law;
 
    - conduct of a director, officer or employee finally adjudged to be an
      unlawful distribution; or
 
    - any transaction with respect to which it was finally adjudged that such
      director, officer or employee personally received a benefit in money,
      property or services to which the director, officer or employee was not
      legally entitled.
 
   
    The legislative history of the Washington Business Corporation Act suggests
that a corporation may indemnify its directors, officers and employees for
amounts paid in settlement of derivative actions, provided that the director's,
officer's or employee's conduct does not fall within one of the categories set
forth above. The Gentle Dental Articles of Incorporation authorize the
corporation to indemnify any of its directors to the fullest extent permitted by
its By-laws and the Washington Business Corporation Act, including an advance of
expenses. Generally, Gentle Dental's By-Laws provide that Gentle Dental shall
indemnify its directors, officers and employees to the fullest extent permitted
by the Washington Business Corporation Act, including indemnification of persons
seeking to enforce indemnification rights through a proceeding authorized by the
Gentle Dental Board of Directors and initiated by such person.
    
 
   
    Under the Delaware General Corporation Law, directors and officers as well
as other employees and agents may be indemnified against expenses (including
attorneys' fees), judgments, fines and amounts paid in a settlement regarding
specified actions, suits or proceedings, which do not include derivative
actions. This indemnification is permitted, however, only if the director,
officer or employee reasonably believed his or her actions were in the best
interests of the corporation. If the matter involves a criminal action or
proceeding, this indemnification is permitted only if the director, officer or
employee had no reasonable cause to believe that his or her conduct was
unlawful. Wisdom Holdings' and Dental Care Alliance's Certificates of
Incorporation each provide for the indemnification of directors and officers to
the fullest extent authorized by Delaware General Corporation Law.
    
 
PROVISIONS AFFECTING CONTROL SHARE ACQUISITIONS AND BUSINESS COMBINATIONS
 
   
    The Washington Business Corporation Act generally prohibits a "target
corporation," from engaging in certain "significant business transactions" with
a person or group of persons that beneficially owns 10% or more of the voting
securities of a target corporation for a period of five years after the
acquisition of such securities. This prohibition does not apply if the
transaction or acquisition of shares is approved by a majority of the members of
the target corporation's board of directors prior to the date of the
acquisition. Significant business transactions with an acquiring person
includes, among other things, a merger or consolidation, disposition of assets
or issuance or redemption of stock. A termination of 5% or more of the employees
of the target corporation employed in State of Washington as a result of the
acquiring person's acquisition of 10% or more of the shares allowing the
acquiring person to receive any disproportionate benefit as a shareholder would
also be a significant business transaction. Target corporations include
    
 
                                      112
<PAGE>
   
domestic corporations with their principal executive offices in and either a
majority or over 1,000 of their employees residing in the State of Washington.
Gentle Dental does not believe that it currently meets these standards or that
it is subject to the statute. A corporation may not "opt out" of this statute.
    
 
   
    Section 203 of the Delaware General Corporation Law prohibits a Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for three years following the date that such person becomes an
interested stockholder. Generally, an interested stockholder is a person or
group who owns 15% or more of the corporation's outstanding voting stock
(including any rights to acquire stock pursuant to an option, warrant,
agreement, arrangement or understanding, or upon the exercise or conversion of
exchange rights), or is an affiliate or associate of the corporation and was the
owner of 15% or more of such voting stock at any time within the previous three
years.
    
 
    For purposes of Section 203, the term "business combination" is defined
broadly to include the following:
 
    - mergers with or caused by an interested stockholder;
 
    - sales or other dispositions to an interested stockholder (except pro rata
      with the corporation's other stockholders) of assets of the corporation or
      a subsidiary having 10% or more of the aggregate market value of the
      corporation's consolidation assets or its outstanding stock;
 
    - the issuance of transfer by the corporation or a subsidiary of stock of
      the corporation or such subsidiary to the interested stockholder (except
      for certain transfers in a conversion or exchange or a pro rata
      distribution or certain other transactions, none of which increase the
      interested stockholder's proportionate ownership of any class or series of
      the corporation's or such subsidiary's stock); or
 
    - receipt by the interested stockholder (except proportionately as a
      stockholder), directly or indirectly, of any loans, advances, guarantees,
      pledges or other financial benefits provided by or through the corporation
      or a subsidiary.
 
    The three-year restriction on business combinations under Section 203 does
not apply in the following circumstances:
 
    - prior to the date at which the stockholder becomes an interested
      stockholder the board of directors approves either the business
      combination or the transaction which resulted in the person becoming an
      interested stockholder;
   
    - the interested stockholder owns 85% of the corporation's voting stock upon
      consummation of the transaction which made him or her an interested
      stockholder (excluding from the 85% calculation shares owned by directors
      who are also officers of the target corporation and shares held by
      employee stock plans which do not permit employees to decide
      confidentially whether to accept a tender or exchange offer); or
    
 
   
    - on or after the date such person becomes an interested stockholder, the
      board of directors approves the business combination and it is also
      approved at a shareholder meeting by at least 66 2/3% of the voting stock
      not owned by the interested stockholder.
    
 
    Section 203 does not apply if the business combination is proposed prior to
the consummation or abandonment of the proposed transaction, and after the
earlier to occur of the public announcement of the proposed transaction or the
notice required under Section 203 and the proposed transaction:
 
    - constitutes certain (x) mergers or consolidations, (y) sales or other
      transfers of assets having an aggregate market value equal to 50% or more
      of the aggregate market value of all of the assets of the corporation
      determined on a consolidated basis or the aggregate market value of all
      the outstanding stock of the corporation or (z) proposed tender or
      exchange offers for 50% or more of the corporation's outstanding voting
      stock;
 
                                      113
<PAGE>
   
    - is with or by a person who was either not an interested stockholder during
      the last three years or who became an interested stockholder with the
      approval of the corporation's board of directors; and
    
 
    - is approved or not opposed by a majority of the members of the
      corporation's board of directors elected prior to any person becoming an
      interested stockholder during the previous three years (or their chosen
      successors).
 
    A Delaware corporation may elect to "opt out" of, and not be governed by,
Section 203 through a provision in either its original certificate of
incorporation or its bylaws, or an amendment to its original certificate of
incorporation or bylaws, which amendment must be approved by a majority vote of
the stockholders entitled to vote thereon. With a limited exception, such an
amendment would not become effective until 12 months following its adoption.
Neither Dental Care Alliance nor Wisdom Holdings has opted out of Section 203.
 
   
MERGERS, SALES OF ASSETS AND OTHER TRANSACTIONS
    
 
   
    Under the Washington Business Corporation Act, a merger, share exchange or
dissolution of a corporation must be approved by the affirmative vote of a
majority of directors when a quorum is present, and by each group entitled to
vote separately on the plan by two-thirds of all shares of voting stock for each
group entitled to a separate vote on the plan by that voting group, unless
another proportion is specified in the articles of incorporation. The Gentle
Dental Articles of Incorporation provide for the affirmative vote of
shareholders holding a majority of the outstanding voting shares to approve such
a transaction.
    
 
   
    The Washington Business Corporation Act also generally provides that a
corporation may sell, lease, exchange or otherwise dispose of all, or
substantially all, of its property, other than in the usual and regular course
of business, or dissolve, if the board of directors recommends the proposed
transaction to the shareholders and the shareholders approve the transaction by
the affirmative vote of the holders of at lease two-thirds of shares of each
group entitled to vote separately on such proposed transaction, unless another
proportion is specified in the articles of incorporation. The Gentle Dental
Articles of Incorporation provide for the affirmative vote of shareholders
holding a majority of the outstanding voting shares to approve such a
transaction.
    
 
   
    Under the Delaware General Corporation Law, a merger, consolidation or sale
of all or substantially all of the assets of a corporation must be approved by
the board of directors and by a majority (unless the certificate of
incorporation requires a higher percentage) of outstanding stock of the
corporation entitled to vote. No vote of stockholders of a constituent
corporation surviving a merger is required, unless specifically required by the
certificate of incorporation if:
    
 
    - the merger agreement does not amend the surviving corporation's
      certificate of incorporation,
 
    - each share of stock of the surviving corporation outstanding immediately
      prior to the merger is to be an identical outstanding or treasury share of
      the surviving corporation after the merger, and
 
   
    - the number of shares to be issued by the surviving corporation in the
      merger does not exceed twenty percent of the shares outstanding
      immediately prior to the merger. Neither the Dental Care Alliance
      Certificate of Incorporation nor the Wisdom Holdings Certificate of
      Incorporation contains a provision requiring a higher percentage of
      stockholder votes to approve such a transaction.
    
 
ACTION WITHOUT A MEETING
 
   
    Under the Washington Business Corporation Act, shareholder action that may
be taken at a shareholders' meeting may be taken by a public company without a
meeting if written consents describing such action are signed by all
shareholders entitled to vote thereon. The Gentle Dental By-Laws provide for
shareholder action without a meeting and by written consent.
    
 
   
    Under the Delaware General Corporation Law, unless otherwise provided in a
corporation's certificate of incorporation, any action that may be taken at a
meeting of stockholders may be taken without a
    
 
                                      114
<PAGE>
meeting, without prior notice and without a vote if the holders of outstanding
capital stock, having not less than the minimum number of votes that would be
necessary to authorize such action, consent in writing. The Dental Care Alliance
By-Laws provide that stockholders may not take action by written consent. The
Wisdom Holdings By-Laws provide that its stockholders may take action by written
consent.
 
CLASS VOTING
 
   
    Under the Washington Business Corporation Act, a corporation's articles of
incorporation may authorize one or more classes of stock to have special,
conditional or limited voting rights, including the right to vote on certain
matters as a group. The articles of incorporation may not limit the rights of
holders of a class to vote as a group with respect to certain amendments to the
articles of incorporation and certain extraordinary transactions that adversely
affect the rights of holders of that class. The Gentle Dental Articles of
Incorporation authorize the issuance of future series of Gentle Dental preferred
stock. Generally, each series is vested with class voting rights regarding (a)
the issuance or authorization of any additional class of equity stock ranking
prior to the series affected and (b) any amendment of the Gentle Dental Articles
which would adversely affect the powers, preferences or other rights or
privileges of the series. One hundred shares of Gentle Dental Series A preferred
stock, one hundred shares of Gentle Dental Series C preferred stock and
1,628,633 shares of Gentle Dental Series D preferred stock are presently issued
and outstanding and each series is entitled to such class vote to approve the
mergers.
    
 
   
    The Delaware General Corporation Law generally does not require class
voting, except for amendments to the certificate of incorporation that change
the number of authorized shares or the par value of shares of a specific class
or that adversely affect such class of shares. In addition, the Wisdom Holdings
Series A preferred stock, Wisdom Holdings Series C preferred stock and Wisdom
Holdings Series D preferred stock that will be deemed outstanding at the
effective time of the mergers will each be entitled to a class vote regarding
(a) the authorization or issuance, or increase in the authorized amount, of any
class of stock ranking senior to such series of Wisdom Holdings preferred stock
and (b) the approval of any amendment to the Wisdom Holdings Certificate of
Incorporation that would materially and adversely change the specific terms of
such series of Wisdom Holdings preferred stock.
    
 
TRANSACTIONS WITH OFFICERS OR DIRECTORS
 
   
    The Washington Business Corporation Act sets forth a safe harbor for
transactions between a corporation and one or more of its directors. A
conflicting interest transaction may not be enjoined, set aside or give rise to
damages if: (a) it is approved by a majority of qualified directors (but no
fewer than two); (b) it is approved by the affirmative vote of the majority of
all qualified shares after notice and disclosure to the shareholders; or (c) at
the time of commitment, the transaction is established to have been fair to the
corporation. For purposes of this provision, a "qualified director" is one who
does not have either a conflicting interest respecting the transaction or a
familial, financial, professional or employment relationship with a second
director who does have a conflicting interest respecting the transaction, which
relationship would, under the circumstances, reasonably be expected to exert an
influence on the first director's judgment when voting on the transaction.
"Qualified shares" are generally defined as shares other than those beneficially
owned, or the voting of which is controlled, by a director or an affiliate of
the director, who has a conflicting interest in the transaction.
    
 
   
    Under the Delaware General Corporation Law, certain contracts or
transactions in which one or more of a corporation's directors has an interest
are not void or voidable because of such interest provided that certain
conditions, such as obtaining the required approval and fulfilling the
requirements of good faith and full disclosure, are met. Under the Delaware
General Corporation Law, either the stockholders or the board of directors must
approve any such contract or transaction after full disclosure of the material
facts or the contract or transaction must have been "fair" as to the corporation
at the time it was approved. If board approval is sought, the contract or
transaction must be approved by a majority of disinterested directors (even if
less than a majority of quorum).
    
 
                                      115
<PAGE>
DISSENTERS' OR APPRAISAL RIGHTS
 
   
    Under the Washington Business Corporation Act, a shareholder is entitled to
dissent from and, upon perfection of the shareholder's appraisal right, to
obtain the fair value of his or her shares in the event of certain corporate
actions, including certain mergers, share exchanges, sales of substantially all
assets of the corporation, and certain amendments to the corporation's articles
of incorporation that materially and adversely affect shareholder rights.
However, shareholders generally will not have such dissenters' rights if
shareholder approval is not required to effect the corporate action being taken.
    
 
   
    Under the Delaware General Corporation Law, a stockholder of a corporation
participating in certain major corporate transactions may be entitled, under
varying circumstances, to appraisal rights pursuant to which such shareholder
may receive cash in the amount of the fair market value of his or her shares in
lieu of the consideration he or she would otherwise receive in the transaction.
Unless a corporation's certificate of incorporation provides otherwise, such
appraisal rights are not available in the following circumstances:
    
 
    - with respect to the sale, lease or exchange of all or substantially all of
      the assets of the corporation,
 
    - with respect to a merger or consolidation by a corporation with shares
      either listed on a national securities exchange, the Nasdaq Small Cap
      Market, or the Nasdaq National Market or are held of record by more than
      2,000 holders if such stockholders receive only shares of the surviving
      corporation, or shares of any other corporation with similarly listed
      shares or with shares which are either listed on a national securities
      exchange or on Nasdaq or held of record by more than 2,000 holders, plus
      cash in lieu of fractional shares, or
 
    - to stockholders of the corporation surviving a merger if no vote of the
      stockholders of the surviving corporation is required to approve the
      merger because the merger agreement does not amend the existing
      certificate of incorporation, each share of the surviving corporation
      outstanding prior to the merger is an identical outstanding or treasury
      share after the merger, and the number of shares to be issued in the
      merger does not exceed 20% of the shares of the surviving corporation
      outstanding immediately prior to the merger and if certain other
      conditions are met.
 
DIVIDENDS
 
   
    Under the Washington Business Corporation Act, a corporation may make a
distribution in cash or in property to its shareholders upon the authorization
of its board of directors unless, after giving effect to such distribution, (1)
the corporation would not be able to pay its debts as they become due in the
usual course of business or (2) the corporation's total assets would be less
than the sum of its total liabilities plus, unless the corporation's articles of
incorporation permit otherwise, the amount that would be needed if the
corporation were to be dissolved at the time of the distribution to satisfy the
preferential rights of shareholders whose preferential rights are superior to
those receiving the distribution.
    
 
   
    The Delaware General Corporation Law permits a corporation to declare and
pay dividends out of statutory surplus or, if there is no surplus, out of net
profits for the fiscal year in which the dividend is declared or for the
preceding fiscal year as long as the amount of capital of the corporation
following the declaration and payment of the dividend is not less than the
aggregate amount of the capital represented by the issued and outstanding stock
of all classes having a preference upon the distribution of assets. In addition,
the Delaware General Corporation Law generally provides that a corporation may
redeem or repurchase its shares only if such redemption or repurchase would not
impair the capital of the corporation.

                             ADDITIONAL INFORMATION
 
   
DISSENTERS' OR APPRAISAL RIGHTS
    
 
   
    The merger agreement constitutes a plan of merger for which shareholder
approval is required under the Washington Business Corporation Act. Pursuant to
Section 23B.3.010 through 23B.13.310 of the Washington Business Corporation Act,
any shareholder of Gentle Dental who gives proper notice and who does not vote
in favor of the mergers will, upon proper demand, have the right under the
Washington Business Corporation Act to obtain payment of the fair value of his
or her shares of Wisdom Holdings common stock, without giving effect to the
mergers.
    
 
   
    Any shareholder electing to exercise dissenters' rights must file a written
notice of this intent with Gentle Dental, attention of the Secretary, at 222
North Sepulveda Boulevard, Suite 740, El Segundo, California 90245, prior to the
vote, and must not vote his or her shares in favor of the merger agreement. As
provided in Section 23B.13.030, a shareholder whose shares are held in a
brokerage account or by some other nominee must either have the record holder of
the shares file the dissenters' notice on the shareholder's behalf or obtain the
written consent of the record holder and file the shareholder's dissenters'
notice. These documents must be filed with the Secretary of Wisdom Holdings
prior to the vote on the merger agreement. A beneficial shareholder of Wisdom
Holdings common stock who chooses to exercise dissenters' rights must exercise
such rights with respect to all shares of Wisdom Holdings common stock either
beneficially held by such shareholder or over which such shareholder has power
to direct the vote. A VOTE IN FAVOR OF THE MERGER AGREEMENT WILL CONSTITUTE A
WAIVER OF DISSENTERS' RIGHTS. A VOTE AGAINST THE MERGER AGREEMENT WILL NOT
SATISFY THE REQUIREMENT THAT WRITTEN NOTICE BE FILED WITH WISDOM HOLDINGS IN
ORDER TO ASSERT DISSENTERS' RIGHTS.
    
 
   
    For the purpose of dissenters' rights, the fair value of Gentle Dental
shares will be their value immediately prior to the effectiveness of the
mergers, excluding any appreciation or depreciation in anticipation of the
mergers, if any, unless exclusion would be inequitable. Shareholders considering
exercising their dissenters' rights should recognize that the fair value of
their shares of capital stock as determined under Section 23B.13.010 through
23B.13.310 could be more than, the same as or less than the value of their
shares if they do not exercise their appraisal rights.
    
 
   
    If the merger agreement is approved by the requisite vote of shareholders,
Wisdom Holdings will, within ten days following the effective date of the
mergers, mail a notice to each shareholder who gave Gentle Dental due notice of
his or her intention to demand payment and who did not vote in favor of the
merger agreement. The notice will provide, among other things:
    
 
   
    - the form of payment demand (including the date of the first announcement
      to the shareholders of the terms of the mergers);
    
 
   
    - where the payment demand must be delivered;
    
 
   
    - when and where the certificated shares must be deposited; and
    
 
   
    - the date by which Gentle Dental must receive the payment demand.
    
 
   
A shareholder who fails to make a timely or proper demand for payment (including
the deposit of certificates) in accordance with the notice is not entitled to
payment under the Washington Business Corporation Act for his or her shares. A
shareholder who fails to certify that he or she acquired beneficial ownership of
the shares prior to the date of the first announcement of the terms of the
mergers to the shareholders may not receive immediate payment for his or her
shares, as described below with respect to after acquired shares (as described
below).
    
 
   
    Except with respect to those shareholders who held after-acquired shares,
Wisdom Holdings will remit, within 30 days of the later of the date of
effectiveness of the mergers or the date the payment demand is received, to all
shareholders who made proper demand, an amount that Wisdom Holdings estimates to
be the fair value of their shares of Gentle Dental common stock, together with
any interest
    
 
                                      117
<PAGE>
   
that has accrued from the effective date of the mergers until the date of
payment. The remittance will be accompanied by certain financial information of
Gentle Dental, an explanation of how the fair value of the shares was estimated
and an explanation of how the accrued interest was calculated. If Wisdom
Holdings fails so to remit or if the dissenting shareholder believes the amount
remitted is less than the fair value of his or her shares, the dissenting
shareholder may send Wisdom Holdings his or her own estimate of the fair value
of the shares and amount of accrued interest due and demand payment of the
deficiency. The dissenting shareholder must notify Wisdom Holdings in writing of
his or her estimate with 30 days after the date Wisdom Holdings mails its
remittance, if any. If Wisdom Holdings and the dissenting shareholder are unable
to agree on a fair value within 60 days after the receipt of a demand for
payment of a deficiency, Wisdom Holdings will petition that the fair value of
the shares and interest thereon be determined by an appropriate court.
    
 
   
    If a dissenting shareholder acquired his or her shares of Capital Stock
after the date set forth in the dissenters' notice, Wisdom Holdings may elect to
withhold the payment described in the preceding paragraph and to offer to pay
fair value for said Gentle Dental after-acquired shares subject to such
dissenting shareholder's agreement to accept payment as satisfaction in full of
the dissenting claim. Wisdom Holdings will send with its offer an explanation of
how the fair value of the Gentle Dental after-acquired shares was estimated and
how the accrued interest was calculated.
    
 
   
    If the dissenting shareholder believes that the amount offered is less than
the fair value of his or her Gentle Dental after-acquired shares, the dissenting
shareholder may send Wisdom Holdings his or her own estimate of the fair value
of the Gentle Dental after-acquired shares and amount of accrued interest due.
The dissenting shareholder must notify Wisdom Holdings in writing of his or
estimate within 30 days after the date Wisdom Holdings makes its offer. If
Wisdom Holdings and the dissenting shareholder are unable to agree on a fair
value for the Gentle Dental after-acquired shares within 60 days after the
receipt of the dissenting shareholder's estimate of the fair value of the Gentle
Dental After-Acquired Shares, Wisdom Holdings will petition that the fair value
of the Gentle Dental after-acquired shares and interest thereon be determined by
an appropriate court.
    
 
   
    With respect to a judicial proceeding commenced by Wisdom Holdings to
determine the fair value of the shares and interest thereon with respect to any
shares of capital stock (including Gentle Dental after-acquired shares), the
court will determine the costs of such proceeding and will assess such costs
against Wisdom Holdings, except that the court may assess such costs against one
or more of the dissenting shareholders party to such proceeding, in amounts the
court finds equitable, to the extent that such court finds that the dissenting
shareholder acted arbitrarily, vexatiously or not in good faith in demanding
payment.
    
 
   
    The foregoing summary is not, and does not purport to be, a complete
statement of dissenters' rights and is qualified in its entirety by reference to
Sections 23B.13.010 through 23B.13.310 of the Washington Business Corporation
Act, a copy of which is attached to this Joint Proxy Statement-Prospectus as
Appendix E.
    
 
LEGAL MATTERS
 
   
    The validity of Wisdom Holdings capital stock to be issued in connection
with the mergers will be passed upon by McDermott, Will & Emery, Newport Beach,
California.

                  UNAUDITED PRO FORMA COMBINED FINANCIAL DATA
    
 
   
    The Unaudited Pro Forma Combined Balance Sheet and Pro Forma Combined
Statements of Operations Data have been prepared by Wisdom based on the Gentle
Dental and Dental Care Alliance Consolidated Financial Statements for the year
ended December 31, 1997 and the nine month period ended September 30, 1998 and
the financial statements of the entities involved in acquisitions completed
during 1997 and 1998. The Pro Forma Combined Financial Data is based on certain
assumptions and adjustments described in the notes hereto and should be read in
conjunction therewith and in conjunction with the complete Gentle Dental
Consolidated Financial Statements and the notes thereto and the Dental Care
Alliance Financial Statements and the notes thereto, and "Management's
Discussion and Analysis of Financial Condition and Results of Operations"
included elsewhere in this Prospectus. The following Pro Forma Combined
Financial Data for the year ended December 31, 1997 and the nine month period
ended September 30, 1998 are unaudited and were prepared by management of the
Company on the same basis as the audited financial statements included elsewhere
herein and, in the opinion of management of the Company, include all adjustments
necessary to present fairly the information set forth herein.
    
 
   
    The Pro Forma Combined Statement of Operations Data for the year ended
December 31, 1997 and the nine month period ended September 30, 1998 give effect
to the following, as if each had occurred on January 1, 1997: (i) the mergers
with Gental Dental, Dental Care Alliance and Wisdom; (ii) the May and June
private placement; (iii) completed acquisitions (including the effect of all
cash, common stock and debt issued or expected to be issued in connection
therewith); and (iv) the effect of the amended Management Agreements with the
Oregon and Washington Professional Corporations.
    
 
   
    The Pro Forma Combined Statements of Operations for the years ended December
31, 1995 and 1996 reflect the mergers of Wisdom, Gentle Dental and Dental Care
Alliance, accounted for using the pooling-of-interests method. The Pro Forma
Combined Statements of Operations for the years ended December 31, 1995 and 1996
have been prepared on the basis of the audited financial statements of the
respective companies. Such 1996 financial statements for Gentle Dental and 1995
and 1996 financial statements for Dental Care Alliance are included elsewhere in
this document. The 1995 financial statements for Gentle Dental were previously
filed in its Form 10-K.
    
 
   
    The Pro Forma Combined Financial Data does not purport to be indicative of
the combined results of operations that actually would have occurred if the
transactions described above had been effected at the dates indicated or to
project future results of operations for any period.

                   NOTES TO PRO FORMA COMBINED FINANCIAL DATA
                                  (UNAUDITED)
    
 
   
    The accompanying pro forma combined financial data presents the pro forma
financial position of Wisdom as of September 30, 1998 and the pro forma results
of operations for the years ended December 31, 1995, 1996, and 1997 and the nine
month period ended September 30, 1998.
    
 
   
    The pro forma combined financial statements reflect the combination of
Gentle Dental Service Corporation and Dental Care Alliance into Wisdom in a
merger expected to be accounted for as a pooling of interests. Accordingly, the
historical amounts have been combined, with adjustments to conform the
accounting policies for depreciation and amortization.
    
 
   
    From January 1, 1997 through December 30, 1998, Gentle Dental acquired 20
dental practices in acquisitions accounted for as purchases. The accompanying
Pro Forma Combined Balance Sheet as of September 30, 1998 includes the effect of
the significant acquisitions completed subsequent to that date and the acquired
non-professional dental practice assets and liabilities and payment of cash,
issuance of common stock and borrowings in connection with completed
affiliations by Gentle Dental, as if they had been completed at September 30,

l)  Represents the impact of consolidating the results of operations of acquired
    dental practices in accordance with EITF 97-2. In connection with Gentle
    Dental's acquisition of these dental practices, revised management service
    and other agreements were entered into which required Gentle Dental to
    consolidate the results of operations of these dental practices. When the
    Company affiliates with dental practices, but does not control the
    operations, such managed dental practices are not consolidated and Gentle
    Dental reports only the management fee revenue. When Gentle Dental controls
    the dental practices, such dental practices are consolidated and Gentle
    Dental reports the net patient service revenue and the related clinical
    salaries and benefits. Consequently, when Gentle Dental shows the impact of
    consolidating dental practices, the effect is to increase revenues and also
    clinical salaries and benefits.
    
 
   
    In Gentle Dental's typical affiliation with consolidated dental practices,
    Gentle Dental acquired the operating assets and assumed certain liabilities
    of the dental groups and entered into long-term service agreements with the
    dental groups. Because of corporate practice of medicine laws in the states
    in which Gentle Dental operates, Gentle Dental does not own dental
    practices, but instead enters into exclusive long-term management services
    agreements with the dental groups. Gentle Dental designates a majority
    shareholder or other owner of the dental group as its nominee. Additionally,
    advisory boards are established which govern the activities of the dental
    practices. Gentle Dental appoints a majority of the advisory board members.
    Through the management services agreements and its control of the advisory
    board and nominee shareholders of the dental practices, Gentle Dental has
    exclusive authority over the decision making related to all major ongoing
    operations of the underlying dental groups with the exception of the
    professional aspects of dentistry practice as required by applicable state
    law. Under the management services agreements, Gentle Dental establishes
    annual operating and capital budgets for the dental groups and compensation
    guidelines for the licensed dental professionals. Gentle Dental consolidates
    the operating results and accounts of the dental groups in accordance with
    EITF 97-2 since Gentle Dental has control over the operations of the dental
    practices.
    
 
   
m) Represents reclassification of payroll and related expenses from Corporate
    selling, general and administrative expense to Practice nonclinical salaries
    and benefits. Practice nonclinical salaries and benefits have also been
    partially offset by a decrease of $1,107 for the year ended December 31,
    1997 and $333 for the nine months ended September 30, 1998 in costs related
    to various positions which were eliminated. As part of the acquisition by
    GDSC, it was agreed to either contractually or verbally with the selling
    dentists, that the positions held by these employees would be eliminated.

n)  Represents the impact of consolidating the results of operations of the
    Oregon and Washington Professional Corporations as a result of the amended
    management agreements in accordance with EITF 97-2. See related discussion
    at note l.
    
 
   
o)  Represents contractually negotiated reductions in building lease expenses.
    As part of the acquisition by GDSC, certain building lease agreements were
    renegotiated and new or modified leases were entered into with the selling
    dentists or facility owners at fair market value rates.
    
 
   
p)  Represents reductions in legal, accounting, certain personal expenses of the
    selling dentists and operating lease expenses. As part of the acquisition by
    GDSC, the selling dentists have agreed to directly pay for legal and
    accounting fees related to the personal matters of the selling dentists and
    certain other expenses, such as automobile expenses. Prior to the
    acquisition by GDSC, the selling dentists had the dental practice pay for
    these expenses.
    
 
   
q)  Represents the increase in amortization expense associated with intangible
    assets of acquired dental practices as if the acquisitions had occurred at
    the beginning of the period. The amortization of intangible assets of
    $94,401 on a pro forma combined basis is over the lesser of the life of the
    contract or 25 years, whichever is shorter. The amortization period will be
    reviewed periodically to determine its appropriateness.
    
 
   
r)  Represents the increase in interest expense that would have been incurred if
    the acquisitions and related financing had occurred at the beginning of the
    period.
    
 
   
s)  Represents the increase in income taxes that would have been incurred if all
    acquired dental practices that were taxed as subchapter S corporations and
    partnerships prior to acquisition by GDSC or DCA had been taxed at full
    corporate income tax rates, considering the effect of Gentle Dental's income
    or loss before income taxes and proforma adjustments.
    
 
   
t)  Represents the reduction in depreciation expense resulting from conforming
    the depreciation policies of DCA to those of GDSC. See additional
    information at note i.
    
 
   
u)  Represents the tax effect of the reduction in depreciation expense described
    in note x.
    
 
   
v)  Represents the elimination of interest income associated with cash and
    investments that were not acquired by GDSC. See additional information at
    note b.
    
 
   
w) Represents the elimination of dividends on redeemable convertible preferred
    stock which was converted into common stock in connection with the 1997
    merger of Gentle Dental and GMS Dental Group as if such stock was converted
    into common stock at January 1, 1997, and the related additional shares
    which would have been outstanding.
    
 
   
x)  Represents management fees and related expenses of the acquired management
    agreements, based on the historical statements of operations of the
    underlying dental practices, as if such acquisitions had occurred at the
    beginning of the period.
    
 
   
y)  Represents dilutive shares as a result of the private placement of
    convertible preferred stock as if such shares were outstanding the entire
    period.
    
 
   
z)  Represents the number of additional shares that each DCA stockholder would
    receive upon the exchange of DCA shares for Wisdom shares:

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders
 
Gentle Dental Service Corporation:
 
    We have audited the accompanying consolidated balance sheet of Gentle Dental
Service Corporation and subsidiaries as of December 31, 1997 and the related
consolidated statements of operations and shareholders' equity and cash flows
for the year ended December 31, 1997 (as restated, see note 15). These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Gentle
Dental Service Corporation and subsidiaries as of December 31, 1997 and the
results of their operations and their cash flows for the year ended December 31,
1997, in conformity with generally accepted accounting principles.
 
    We previously audited and reported on the consolidated balance sheet of GMS
Dental Group, Inc. and subsidiaries as of December 31, 1996 and the related
consolidated statements of operations and shareholders' equity and cash flows
for the year ended December 31, 1996, prior to their restatement for the 1997
pooling of interests between Gentle Dental Service Corporation and subsidiaries
and GMS Dental Group, Inc. and subsidiaries. The contribution of GMS Dental
Group, Inc. and subsidiaries to total assets, revenues and net loss represented
50 percent, 26 percent and 42 percent of the respective restated totals.
Separate financial statements of Gentle Dental Service Corporation included in
the 1996 restated consolidated balance sheet and statements of operations and
cash flows were audited and reported on separately by other auditors. We also
audited the combination of the accompanying consolidated balance sheet as of
December 31, 1996 and the related consolidated statements of operations and cash
flows for the year ended December 31, 1996, after restatement for the pooling of
interests; in our opinion, such consolidated statements have been properly
combined on the basis described in note 3 of the notes to the consolidated
financial statements.

To the Shareholders and Board of Directors of

    In our opinion, the balance sheet and the related statements of operations,
of redeemable common stock and nonredeemable shareholders' equity and of cash

December 31, 1996, and the results of its operations and its cash flows for the
year then ended, in conformity with generally accepted accounting principles.
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 of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the

evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management and evaluating the overall financial statement presentation. We
believe that our audit provides a reasonable basis for the opinion expressed
above.
 
    As disclosed in Note 10 to the financial statements, the Company has certain

(1) ORGANIZATION
 
    Gentle Dental Service Corporation ("GDS" or the "Company"), incorporated on
December 14, 1992, is a Washington corporation headquartered in Yorba Linda,
California. The Company, as part of a multi-specialty dental care delivery
network, provides management services to dental practices ("DPs") under
long-term management service agreements. Under the terms of the management
service agreements, the Company, among other things, bills and collects patient
receivables and provides all administrative support services to the DPs.
 
    On February 13, 1997, the Company completed its initial public offering of
1,500,000 shares of no par value common stock (the "Offering"). The price per
share in the Offering was $5.00, resulting in gross offering proceeds of $7,500.
The Company received net proceeds of approximately $6,125 net of underwriters'
discount and offering expenses. Concurrent with the receipt of the net proceeds,
the company utilized $4,426 to repay certain outstanding principal under the
Company's various bank loan arrangements (see note 6).
 
(2) BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
 
    The consolidated financial statements include the accounts of GDS and its
subsidiaries. All significant intercompany transactions and accounts have been
eliminated. As described more fully in Note 3, on November 4, 1997, GMS Dental
Group, Inc. ("GMS") was merged with and into the Company, with former
stockholders of GMS owning 59% of the combined company upon completion of the
merger. These consolidated financial statements have been prepared following the
pooling-of-interests method of accounting and reflect the combined financial
position and operating results of GDS and GMS (and certain affiliated DPs as
discussed below) for all periods presented. GMS commenced operations on October
11, 1996. Accordingly, its results of operations for 1996 included only
approximately 2 2/3 months.
 
    The Emerging Issues Task Force ("EITF") of the Financial Accounting
Standards Board recently evaluated certain matters relating to the physician
practice management industry (EITF issue number 97-2) and reached a consensus on
the accounting for transactions between physician practice management companies
and physician practices and the financial reporting of such entities. For
financial reporting purposes, EITF 97-2 mandates the consolidation of physician
practice activities with the practice management company when certain conditions
have been met, even though the practice management company does not have an
equity investment in the physician practice. The accompanying financial
statements are prepared in conformity with the consensus reached in EITF 97-2.
 
    Corporate practice of medicine laws in the states in which the Company
currently operates prohibit the Company from owning dental practices. In
response to these laws the Company has executed management services agreements
("MSAs") with various DPs. Based upon the terms of MSAs with certain of the DPs,
the Company has met the criteria for consolidation of those DPs with the
Company. In these circumstances, all the accounts of the DPs are included in the
accompanying consolidated financial statements. Accordingly, the consolidated
statements of operations include the net patient revenues and related expenses
of the DPs.
 
    In addition to the MSAs discussed above, the Company has entered into MSAs
with certain DPs where the Company has not met the criteria for consolidation of
the DPs activities. In these circumstances, the Company does not consolidate the
accounts of the DPs. Accordingly, the consolidated statements of operations
exclude the net patient revenues and expenses of the DPs. Rather, the statements
of operations

include only the Company's net management fees revenue generated from those MSAs
and the Company's expenses associated with those MSAs. Subsequent to December
31, 1997, the Company entered into new MSAs with the Oregon and Washington DPs.
Effective January 1, 1998 the criteria has been met for consolidation of these
DPs financial statements with the Company (see note 14).
 
    The Company has a 50% equity investment in Celebration Dental Services
L.L.C., a Florida limited liability company, which is accounted for on the
equity basis of accounting and is included in other expense, net.
 
    NET REVENUES
 
    Revenues consist primarily of DP net patient service revenue (net patient
revenue) and Company net management fees. Net patient revenue represents the
consolidated revenue of the DPs reported at the estimated net realizable amounts
from patients, third party payors and others for services rendered, net of
contractual adjustments. Net management fees represent amounts charged to the
unconsolidated DPs on an agreed-upon percentage of the DPs net patient service
revenue under MSAs, net of provisions for contractual adjustments and doubtful
accounts. The components of net revenues are as follows:

    CASH AND CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents.
 
    ACCOUNTS RECEIVABLE
 
    Accounts receivable principally represent receivables from patients and
insurance carriers for dental services provided by the related DPs and are
recorded net of contractual adjustments and allowance for doubtful accounts.
Contractual allowances represent an estimate of the difference between the
amount billed by the Company and the amount which the patient, third party payor
or other is contractually obligated to pay the Company. An allowance for
doubtful accounts is provided based upon historical collection experience.
 
    RECEIVABLES FROM AFFILIATES
 
    Receivables from affiliates consist primarily of amounts owed to the Company
from unconsolidated DPs to reimburse the Company for payment of the DPs payroll
and other direct costs, net of amounts due to the DPs related to the
acquisitions and the DPs share of revenues (see notes 10 and 14)

    INTANGIBLE ASSETS
 
    Intangible assets result primarily from the excess of cost over the fair
value of net tangible assets purchased. Such intangibles relate primarily to
noncompetition covenants and management services agreements. Intangibles
relating to management service agreements consist of the costs of purchasing the
rights to provide management support services to DPs over the initial
noncancelable 40-year terms of the related agreements. Under these agreements,
the DPs have agreed to provide dental services on an exclusive basis only
through facilities provided by the Company. Pursuant to the terms of the
agreements, the Company is the exclusive administrator of all non-dental aspects
of the acquired DPs, providing facilities, equipment, support staffing,
management and other ancillary services. The agreements are noncancelable except
for performance defaults.
 
    Intangible assets are amortized on the straight-line method over their
estimated useful lives, 5 years for organizational costs, 25 years for
management services agreements and other acquired intangibles, and 40 years for
trademarks.
 
    LONG-LIVED ASSETS
 
    The Company reviews its assets balances for impairment at the end of each
quarter or more frequently when events or changes in circumstances indicate that
the carrying amount of assets may not be recoverable. To perform that review,
the Company estimates the sum of expected future undiscounted net cash flows
from assets. If the estimated net cash flows are less than the carrying amount
of the asset, the Company recognizes an impairment loss in an amount necessary
to write-down the asset to a fair value as determined from expected future
discounted cash flows. No write-down of assets was recorded for the years ended
December 31, 1996 and 1997.

(2) BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    FAIR VALUE OF FINANCIAL ASSETS, LIABILITIES AND REDEEMABLE COMMON STOCK
 
    The Company estimates the fair value of its monetary assets, liabilities and
redeemable common stock based upon the existing interest rates related to such
assets, liabilities and redeemable common stock compared to current market rates
of interest for instruments with a similar nature and degree of risk. The
Company estimates that the carrying value of all of its monetary assets,
liabilities and redeemable common stock approximates fair value as of December
31, 1996 and 1997.
 
    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,
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
    NET LOSS PER SHARE
 
    Net loss per share is computed based on the weighted average number of
shares of common stock and dilutive common stock equivalents outstanding during
the periods. Common stock equivalents consist of the number of shares issuable
upon exercise of the outstanding common stock warrants and common stock options
(using the treasury stock method). Common stock equivalents have been excluded
from the computation of loss per share as their effect is anti-dilutive. The
weighted average common shares utilized for the years ended December 31, 1996
and 1997 were 1,707,095 and 4,559,140 (as restated--see note 15), respectively.
 
    NEW ACCOUNTING PRONOUNCEMENTS
 
    In February 1997, the Financial Accounting Standards Board issued SFAS No.
128 Earnings Per Share. In accordance with this pronouncement, the Company
adopted the new standard for the years ended December 31, 1996 and 1997. The
adoption of this pronouncement did not have an effect on reported loss per share
information.
 
    STOCK-BASED COMPENSATION
 
    In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123 ("SFAS 123"), Accounting for
Stock-Based Compensation. Under SFAS 123, the Company may elect to recognize
stock-based compensation expense based on the fair value of the awards or
continue to account for stock-based compensation under Accounting Principles
Board Opinion No. 25, Accounting for Stock Issued to Employees' and disclose in
the financial statements the effects of SFAS 123 as if the recognition
provisions were adopted. The Company has elected to account for stock-based
compensation under Accounting Principles Board Opinion No. 25 ("APB 25").

(3) BUSINESS COMBINATIONS AND DENTAL PRACTICE ACQUISITIONS
 
    BUSINESS COMBINATIONS
 
    On November 4, 1997, GMS merged into GDS. In connection with the merger
transaction, all of the issued and outstanding shares of GMS common stock were
converted into 4,548,161 shares of common stock of the Company.
 
    The merger has been accounted for using the pooling-of-interests method of
accounting. Accordingly, the historical financial statements for the periods
prior to the completion of the combination have been restated as though the
companies had been combined. The restated financial statements have been
adjusted to conform the lives in computing depreciation of equipment and
amortization of intangible assets. Such adjustments resulted in no change in
amortization expense in 1996 and in a decrease in depreciation expense of $24 in
1996. Additionally, such adjustments resulted in a decrease in the 1996 income
tax benefit of $10.
 
    The results of operations of GMS and GDS for 1997 through the date of the
merger are as follows:

    As a result of the merger, the Company recorded direct merger expenses of
$677. These expenses consist primarily of accounting, legal and other advisory
fees. Also, the Company recorded a restructuring charge of $1,132, or $.25 per
share (as restated, see note 15), in the fourth quarter of 1997. The charge
included $289 for employee related costs, $311 for facility consolidation and
related leasehold and fixed asset write-offs and $532 for the redirection of
certain duplicative operations and programs and other costs. These charges are
scheduled to be substantially completed in 1998. At December 31, 1997, the
Company's remaining obligation related to the restructuring charges was $853 and
is included in other current liabilities in the accompanying financial
statements.
 
    DENTAL PRACTICE ACQUISITIONS
 
    In 1996, the Company acquired substantially all of the assets of 15 dental
office locations, including cash, accounts receivable, supplies and fixed
assets. The total price for the fair value of the assets acquired, including
intangible assets was $12,914. Approximately $8,501 of the purchase price has
been allocated to intangible assets. The total purchase consideration included
$7,268 in cash, $2,725 in redeemable and nonredeemable preferred and common
stock and $2,921 in liabilities issued or assumed.
 
    In 1997, the Company acquired substantially all of the assets of 15 dental
office locations, including cash, accounts receivable, supplies and fixed
assets. The total price for the fair value of the assets acquired, including
intangible assets was $17,459. Approximately $13,213 of the purchase price has
been allocated to intangible assets. The total purchase consideration included
$9,706 in cash, $1,991 in nonredeemable preferred and common stock and warrants
and $5,762 in liabilities issued or assumed.
 
    In connection with the affiliation of certain dental practices, the Company
is obligated to pay additional consideration, depending upon the achievement of
certain financial results, as defined by the

purchase agreements. During 1997, the Company accrued $356 for the portion of
1997 earnouts which the Company expects to pay in common stock. Additional
consideration may be payable in cash or stock depending upon the performance of
certain affiliated practices. The additional consideration to be paid under
these agreements is not presently determinable. However, such additional
consideration, if any, is not expected to have a material impact on the
financial condition or on the results of operations of the Company.
 
    The above asset purchases in 1996 and 1997 have been accounted for using the
purchase method of accounting. The excess of the total purchase price over the
fair value of the net tangible and identifiable intangible assets acquired
representing the estimated future value of the management services agreements
are being amortized over the lesser of the term of the related management
service agreements or 25 years using the straight-line method. The results of
operations for these practices have been included in the consolidated financial
statements of the Company since the dates of their affiliation.
 
    The following unaudited pro forma information presents the condensed
consolidated results of operations as if the 1996 and 1997 affiliations
discussed above had occurred as of January 1, 1996. The pro forma results have
been prepared for comparative purposes only and are not necessarily indicative
of what the actual results of operations would have been had the practices been
affiliated as of that date, nor does it purport to represent future operations

    SHORT-TERM BORROWINGS
 
    At December 31, 1996, the Company had a total of $2,097 outstanding under
two bank operating lines of credit with a bank secured by substantially all
assets of the Company. In February 1997, the entire outstanding amount was fully
repaid from the net proceeds from the Offering (see note 1).
 
    LONG-TERM DEBT
 
    At December 31, 1997, the Company had a credit facility from a bank in the
amount of $10,000 (which was increased to a $25,000 credit facility on January
7, 1998, see note 14). The proceeds of the credit facility are available for
working capital needs and to finance dental practice asset acquisitions.
Principal amounts owed under the credit facility through December 31, 1997 bear
interest up to 1% above the prime rate or up to 3.25% above LIBOR, at the
Company's option, dependent on the Company's leverage ratio. The outstanding
balance on this facility as of December 31, 1997 was $10,000. The obligations
under this credit agreement are secured by substantially all assets of the
Company and its subsidiaries.

(7) SHAREHOLDERS' EQUITY
 
    As of December 31, 1996, the Company had only common stock outstanding and
GMS had two classes of stock outstanding: common stock and preferred stock. GMS
preferred stock outstanding consisted of convertible preferred stock--Series A,
redeemable convertible preferred stock--Series B and convertible preferred
stock--Series C. The redeemable convertible preferred stock--Series B, including
dividends and the convertible preferred stock--Series A and C, were converted
into 7,603,677 shares (3,384,302 shares of GDS common stock) of GMS common stock
on November 4, 1997 prior to the GMS merger. Upon closing of the merger between
GMS and the Company, all 10,218,578 outstanding GMS common shares were converted
into 4,548,161 shares of the Company's common stock.
 
    COMMON STOCK
 
   
    An aggregate of 608,524 shares of common stock were issued in 1996 at a
purchase price of $.225 per share, which equaled the fair market value of the
stock on the date of issuance, to the founders of GMS. 269,278 of these shares
are subject to a four-year vesting schedule whereby one-quarter of the shares
vested upon issuance and one-quarter of the shares vested in October 1997. The
remaining shares vest on a monthly basis during the remaining thirty-six months.
    
 
    An aggregate of 254,901 shares issued to certain other shareholders, which
were issued at a price of $.45 per share, and 339,246 shares out of the 608,524
shares issued to GMS founders, are subject to, in certain events, a right of
repurchase by the Company, at cost. One half of the shares are currently subject
to repurchase because the Company's EBITDA (excluding CEO salary and related
expenses) for 1997 did not exceed $4,724. The second half of the shares will be
subject to repurchase if, among other things, the Company's EBITDA (excluding
CEO salary and related expenses) for 1998 does not exceed $12,683, and a portion
of the second half will be subject to repurchase if such EBITDA does not exceed
$16,911.
 
    PREFERRED STOCK
 
    Preferred stock may be issued by the Board of Directors with preferences to
be determined at the time of issuance. Through December 31, 1997, none of the
30,000,000 authorized shares of the Company's preferred stock has been issued or
is outstanding.

    STOCK WARRANTS ISSUED IN CONJUNCTION WITH DEBT ISSUANCE AND ACQUISITIONS
 
    In May 1996 the Company issued warrants to purchase 4,333 shares of the
Company's common stock at $7.50 per share to a lender in connection with a line
of credit agreement. The stock warrants were valued at $9 and have been recorded
as debt issuance costs and additional paid-in capital. The estimated fair value
of the stock warrants was amortized over the six-month term of the line of
credit. Such amortization expense has been included in interest expense in the
statement of operations. The stock warrants expire on May 31, 2001 and carry
certain piggyback registration rights. The stock warrants have not been
exercised to date.
 
    In addition, in May 1996, the Company issued to certain directors, officers
and shareholders of the Company warrants to purchase 115,000 shares of the
Company's common stock at $7.50 per share in consideration for guaranteeing a
total of $1,000 of a line-of-credit which is no longer available and has been
fully repaid. The fair value of the stock warrants of $233 was amortized over
the six-month term of the line of credit. Such amortization expense has been
included in interest expense in the statement of operations. All stock warrants
expire in May 2001 and no such stock warrants have been exercised to date.
 
    In connection with the Company's $10 million credit facility, warrants were
issued in 1996 entitling the bank to purchase up to 81,942 shares of the
Company's common stock at a price of $3.93 per share. The warrants were recorded
at their estimated fair market value of $1 which is included in interest expense
in the accompanying financial statements. These warrants expire in October 2001.
 
    In connection with the Company's initial public offering, warrants were
issued in 1997 entitling representatives of the underwriters to purchase up to
150,000 shares of the Company's common stock at a price of $6.00 per share.
These warrants were recorded at their estimated fair value of $1.
 
    In connection with the acquisition of the net assets of dental practices in
1997, the Company issued warrants to purchase approximately 189,160 shares of
common stock at $7.86 per share. The warrants expire in 2004; no such stock
warrants have been exercised to date. Warrants for 22,254 shares become
exercisable only if certain performance conditions are met by the acquired
dental practices. The estimated fair value of $4 was recorded as part of the
consideration for the acquisition.

    REDEEMABLE COMMON STOCK
 
    In connection with certain acquisitions, the Company granted put rights to
certain shareholders that may require the Company to redeem up to 96,545 shares
of its common stock, at a redemption price ranging from $13.38 to $19.62 per
share. If all shareholders with such put rights exercise their options, the
Company would be required to repurchase the above shares of common stock for
$1,409. The redemption periods began April 1, 1996 and continue through January
4, 2003. If the shareholder does not place a redemption request during the
redemption period, the put right will expire on the stated expiration date. Put
rights for all but 20,000 shares terminate in the event of the Company
successfully completing a public offering at a price of at least $20.00 per
share. The Company redeemed 6,243 shares of redeemable common stock for $90
during 1996 and 6,616 shares for $103 during 1997.
 
    The shares of common stock subject to the put rights are reported on the
balance sheet as redeemable common stock. Such shares have been recorded at
their fair value as of date of acquisition, inclusive of accretion during each
of the two years in the period ended December 31, 1997. The Company records
accretion on a ratable basis over the redemption period of the respective stock.
Such accretion for the years ended December 31, 1996 and 1997 was $91 and $34,
respectively.

    PRIVATE PLACEMENT OF REDEEMABLE COMMON STOCK AND WARRANTS
 
    In June 1996, the Company completed a private placement offering (the
"Placement Offering") of 100,000 shares Company's redeemable common stock which
include warrants to purchase 100,000 additional shares of the Company's common
stock at an exercise price of $7.50 per share. Total proceeds from the Placement
Offering (net of Placement Offering costs of $43) were $957. The net proceeds
allocated to common stock aggregated $732. The stock warrants were recorded at
their estimated fair value of $225 and are entitled to certain piggyback
registration rights. The stock warrants expire on December 14, 2001; no stock
warrants have been exercised to date.
 
    In connection with the private placement, the shareholder received certain
put rights which are exercisable after June 21, 2001 but not later than June 21,
2003 if the Company has not completed a public offering of its common stock by
June 21, 2001 at a price of at least $22.00 per share and with net proceeds to
the Company of at least $10,000. The per share price applicable to the put
rights is 20 times the Company's average adjusted net income per share for the
two most recent fiscal years preceding the exercise of the rights. As of
December 31, 1997, the Company has not recorded any accretion related to the
above put rights.
 
(9) STOCK OPTIONS
 
    The Company has adopted a Stock Incentive Plan (the "Plan"). The Plan
provides for issuance of up to 1,000,000 shares of common stock in connection
with various stock grants, awards and sales granted under such plan to employees
and non-employees (primarily key dental group personnel). The Plan authorizes
the grant of incentive stock options, non-statutory stock options, stock
appreciation rights or bonus rights; award of stock bonuses; and/or sale of
restricted stock. The exercise price for incentive stock options may not be less
than fair market value of the underlying shares on the date of grant. The Plan
is administered by the Company's Board of Directors. The Board has the authority
to determine the persons to whom awards will be made, the amounts, and other
terms and conditions of the awards. Shares issued under the Plan are generally
subject to a five- year vesting schedule from the date of grant and expire ten
years from the original grant date.

(9) STOCK OPTIONS (CONTINUED)
    On February 13, 1997 (the offering date), the Company repriced all employee
stock options than outstanding to the offering price of $5.00 per share (except
for certain stock options held by a principal shareholder, which were repriced
at 110% of the offering price). All other terms with respect to such options
were maintained. The Company did not recognize compensation expense related to
the repricing of the employee stock options as the adjusted exercise price was
not below the fair value of the common stock as of the repricing date.
 
    Prior to the merger, GMS had two stock-based option plans ("Former Plans")
which offered essentially the same awards and stock option terms as the Plan.
Upon consummation of the merger of GMS with the Company, the Former Plans were
frozen to allow no additional option grants under those plans. The number of
options and option price for the options granted under the Former Plans were
converted to the Company share and share price equivalent utilizing the same
conversion ratio of GMS common stock to Company common stock.
 
    Stock options issued to non-employees have been recorded at their estimated
fair market value and are being expensed over their respective vesting lives of
up to five years. Total compensation expense recorded for the years ended
December 31, 1996 and 1997 was $52 and $56, respectively.
 
    STATEMENT OF FINANCIAL ACCOUNTING STANDARDS NO. 123 ("SFAS 123")
 
    The Financial Accounting Standards Board has issued SFAS 123, Accounting for
Stock Based Compensation, which defines a fair value based method of accounting
for employee stock option or similar compensation plans. However, it also allows
an entity to continue to measure compensation cost related to stock options
issued to employees under these plans using the method of accounting prescribed
by the Accounting Principles Board Opinion No. 25 ("APB 25"), Accounting for
Stock Issued to Employees. Entities electing to remain with the accounting in
APB 25 must make pro forma disclosures of net income and earnings per share, as
if the fair value based method of accounting defined in this Statement had been
applied.
 
    The Company has elected to account for its stock-based compensation plans
under APB 25; however, the Company has computed for pro forma disclosure
purposes the value of all options granted during the years ended December 31,
1996 and 1997. The 1996 options were valued using the minimum value pricing
model as prescribed by SFAS 123 for nonpublic companies. The options issued
subsequent to the Company's 1997 initial public offering have been valued using
the Black-Scholes pricing model as prescribed by SFAS 123. The following
weighted average assumptions have been used for grants of stock options:

(9) STOCK OPTIONS (CONTINUED)
    Options were assumed to be exercised over the five-year expected life for
the purpose of this valuation. Adjustments are made for options forfeited prior
to vesting. The total value of options granted was computed as the following
approximate amounts, which would be amortized on the straight-line basis over
the vesting period of the options:

    If the Company had accounted for stock options issued to employees in
accordance with SFAS 123, the Company's net loss attributable to common stock
and pro forma net loss per share would have been reported as follows:

    The effects of applying SFAS 123 for providing pro forma disclosures for
1996 and 1997 are not likely to be representative of the effects on reported net
loss and net loss per common equivalent share for future years, because options
vest over several years and additional awards generally are made each year.

    LITIGATION
 
    The Company is subject to various claims and legal actions which arise in
the ordinary course of business. In the opinion of management, the ultimate
resolution of such matters will not have a material adverse effect on the
Company's financial position or results of operations
 
(14) SUBSEQUENT EVENTS
 
    On January 7, 1998, the Company amended its $10 million credit facility (the
"Credit Facility") to provide for a maximum credit line of $25 million, which
may be increased at the option of the Company to $30 million following
completion of an equity offering by the Company in which the Company receives at
least $20 million in net cash proceeds. The Company intends to use the Credit
Facility for working capital requirements, to purchase non-professional dental
practice assets of additional dental practices that the Company may seek to
affiliate with, and to purchase operating assets for existing affiliated dental
practices. The Credit Facility provides that the aggregate amount borrowed under
the Credit Facility for working capital purposes and letter of credit
obligations may not exceed $4 million, and that remaining amounts available
under the Credit Facility may be used by the Company for permitted acquisitions
and capital expenditures. The revolving feature of the Credit Facility expires
on September 30, 1999, at which time it will convert into a three year term loan
to be repaid in 12 equal quarterly installments. Principal

amounts owed under the Credit Facility bear interest, at the Company's option
and dependent upon the Company's leverage ratio, of (i) up to 1.0% over prime or
(ii) up to 3.25% above LIBOR. The Credit Facility requires the Company to pay an
unused commitment fee based upon a range from .375-.50% of the amount by which
the bank commitment under the Credit Facility exceeds the aggregate amount of
all loans then outstanding. The Credit Facility contains several covenants
including (i) restrictions on the ability of the Company to incur indebtedness
and repurchase, or pay dividends with respect to, its capital stock; and (ii)
requirements relating to maintenance of a specific net worth and specified
ratios of current assets to current liabilities, debt to cash flow and EBITDAR
(earnings before interest expense, taxes, depreciation, amortization and
operating lease rental expense) to fixed charges. In addition, the Credit
Facility requires the Company to notify the lenders prior to making any
acquisition and to obtain the consent of the lenders prior to making (i) certain
acquisitions with purchase price exceeding $3 million, (ii) all acquisitions
with purchase prices exceeding $5 million and (iii) capital expenditures
exceeding $5 million in any fiscal year. The Credit Facility also requires the
Company to convert to a holding company that owns no assets other than the stock
of its operating subsidiaries on or before May 31, 1998. If the Company does not
attain holding company status on or before May 31, 1998, the interest rate
applicable to amounts borrowed under the Credit Facility will be increased by
0.5% and if holding company status is not obtained on or before July 31, 1998 an
event of default will exist under the terms of the Credit Facility. The
Company's obligations under the Credit Facility are guaranteed by each of the
subsidiaries of the Company. The obligations of the Company under the Credit
Facility and the subsidiaries under the guarantees are secured by a security
interest in the equipment, fixtures, inventory, receivables, subsidiary stock,
certain debt instruments, accounts and general intangibles of each of such
entities.
 
    The Company and its related Washington and Oregon DPs entered into asset
purchase and management service agreements (collectively, the Agreements) on
January 1, 1998. The new management service agreements meet the criteria for
consolidation of the DP accounts with the Company for financial reporting
purposes as outlined in EITF 97-2.
 
    Under the terms of the Agreements, the Company acquired all of the fixed
assets and assumed certain liabilities of the DPs. In exchange, the Company paid
consideration of $1,674, which was offset by the Company's $1,674 receivable
from the DPs. In addition, the Company issued options to purchase 110,000 shares
of Company common stock at an exercise price of $8.38 per share, subject to a
five-year vesting schedule and will pay $575 in cash over 18 equal monthly
installments. Also, the Company may pay possible minimal future consideration in
cash or options to be determined upon the achievement of certain financial
results, as defined in the Agreements.
 
    In 1998 the Company completed the acquisitions of two DPs located in
northern California and western Oregon, representing ten clinical office
locations. The purchase price for these affiliations totalled $8,410 and
included cash and 43,077 shares of common stock. These affiliations will be
accounted for using the purchase method of accounting.
 
    On February 28, 1998 the Company signed a definitive agreement to acquire
Managed Dental Care of Oregon, Inc. (MDC). MDC is a dental care organization
that contracts with the state of Oregon to provide care under the Oregon Health
Plan. MDC in turn contracts with dental care providers to provide dental care to
Oregon Health Plan participants. The cash purchase price is $950 and the
acquisition is subject to

Oregon state regulatory approval. The acquisition is expected to close during
1998 and will be accounted for using the purchase method of accounting.
 
    During September 1997, the Company entered into definitive agreements to
acquire Dedicated Dental Systems, Inc. (DDS) and the assets of certain related
practices. The acquisition includes 15 dental offices located in and around
Bakersfield, CA. On February 28, 1998 the definitive agreements were amended and
now provide for a purchase price of $16,431 in cash and 705,101 shares of common
stock valued at $5,769 plus potential future amounts based on performance. The
acquisition of DDS is expected to close during 1998 and is subject to California
state regulatory approval. The acquisition will be accounted for using the
purchase method of accounting.
 
    During March 1998, the Company entered into an agreement to lease office
space for a period of sixty months commencing May 1998 at a monthly base rent of
$15.
 
(15) RESTATEMENT OF CONSOLIDATED FINANCIAL STATEMENTS

correction of an error in the weighted average number of shares of common stock
outstanding for the year ended December 31, 1997. As a result of this
correction, the following amounts were restated as of and for the year ended

To the Board of Directors and
Stockholders of Dental Care Alliance, Inc.
 
    In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of stockholders' equity and of cash flows
present fairly, in all material respects, the financial position of Dental Care
Alliance, Inc. (the "Company") successor to Golden Care Holdings, Inc. and its
subsidiaries at December 31, 1997 and 1996, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1997, in conformity with generally accepted accounting principles. 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 of these statements in accordance with
generally accepted auditing standards which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

                           DENTAL CARE ALLIANCE, INC.
                   (SUCCESSOR TO GOLDEN CARE HOLDINGS, L.C.)
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. OPERATIONS AND ORGANIZATION
 
    Dental Care Alliance, Inc. ("DCA" or the "Company") was formed on October
23, 1996 with a nominal capital contribution, to effect a reorganization (the
"Reorganization") among DCA, Golden Care Holdings L.C. ("GCH"), the predecessor
entity, and its majority owned subsidiaries Golden Care Network, L.C. ("GCN"),
and Prophet Management L.C. ("PM"). DCA and GCH completed the Reorganization on
October 25, 1996 by transferring substantially all of the assets, liabilities
and operations of GCH, GCN and PM to DCA. Concurrently, shares of DCA were
issued in exactly the same proportion as the shareholders of GCH. Effective
November 4, 1997, the Company completed an Initial public offering of its stock.
All per share amounts have been adjusted retroactively to reflect the stock
split completed in anticipation of this transaction.
 
    As the shareholders of DCA and GCH, and their related ownership percentages,
were identical at the time of the Reorganization, the Reorganization has been
accounted for in a manner similar to a pooling of interests. The effects of the
Reorganization, resulting in the recording of deferred income taxes upon
conversion to C corporation status, have been reflected in these financial
statements.
 
    GCH was incorporated in 1993 as a Florida Limited Liability Corporation
which held 99% of GCN and 90% of PM. Concurrent with the Reorganization, the 10%
minority shareholder interest of PM transferred his ownership interest in the
assets of PM in exchange for 81,540 shares of the stock of DCA. These shares
were issued to the minority shareholder at fair market value of $1.53 per share
as determined by an independent third party appraisal of the common stock of the
Company as of this date. As a result of this transaction, $125,000 was
capitalized and is reflected as a component of intangible assets in the
underlying financial statements and is being amortized over fifteen years. No
step up in basis for the 1% minority share of GCH has been reflected, as the
stockholders and stockholders' percentages of DCA and GCH were exactly the same
on the date of the Reorganization, and the fair value of the 1% ownership
interest is not material.
 
    The Company and its predecessor provide management, consulting and licensing
services to dental practices in Florida, Michigan and, effective in March 1998,
Georgia. The dental practices are owned by separate Professional Associations
(the "PAs"), and the Company has entered into long-term Administrative Services
Agreements ("Management Agreements") with the P.A.s to provide administrative,
financial and technical support and expertise to the P.A.s in exchange for
management, consulting and licensing fees, as described in Note 3.
 
    Each PA employs and directs the professional dental staff, including the
dentists and hygienists, and provides all of the clinical services to the
patients. The Company employs and directs the administrative staff and manages
in collaboration with the PA owner, all of the remaining administrative,
financial, marketing and professional services of the practice. As of December
31, 1997, the Company provided these management services to 29 Managed Dental
Centers, 24 located in Florida and 5 in Michigan. As of December 31, 1995, 1996
and 1997, of the 9, 12 and 29 Managed Dental Centers, 6, 10 and 16 centers were
owned and controlled by the same individual and resulted in $288,000, $1,022,000
and $4,508,000, for each of the years then ended, of the Company's management
fees, respectively. As further described in Note 3, in 1996, the 10 Management
Agreements were modified concurrent with the Reorganization, in exchange for
81,540 shares of the Company's common stock and assumption of the existing
working capital liabilities of the PAs of $438,300. The fair value of these
shares ($125,000) and the working capital liabilities assumed have been recorded
as an intangible asset and are being amortized over the 25 year life of the
agreements.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1. OPERATIONS AND ORGANIZATION (CONTINUED)
    The Company also provides consulting services to other PAs, under contracts
in which the PA employs the administrative staff. Under such agreements, the
Company reviews and consults on the financial and operational efficiencies of
the practices. These consulting agreements were originally held by an entity
which is approximately 80% controlled by the Company's President and controlling
stockholder. The 20% minority stockholder assigned his interest in these
agreements to the Company on October 25, 1996 in exchange for 40,770 shares of
the Company's common stock which was valued at $1.53 per share, as determined by
an independent third party appraisal. As a result of this transaction, $62,500
was capitalized and is reflected as a component of intangible assets in the
underlying financial statements and is being amortized over the eight year
remaining life of these agreements. As of December 31, 1996, the Company
provided these consulting services to four Managed Dental Centers, all located
in Michigan.
 
    In July 1997, the Company acquired the Management Agreements for these four
Managed Dental Centers for $846,000, including a credit related to outstanding
receivables for consulting services of $300,000 (which is forgiven ratably over
the term of the associated Management Agreements), wherein it provides
management services to the related practices for eight years. The acquired
Management Agreements are executed under the net revenue contract (see Note 3).
Unaudited net practice revenue of the dental practice was approximately $3.4
million for the period ended December 31, 1996. The Company had previously
recognized revenue of $160,000 in 1996 and $53,000 for six months ended June 30,
1997, for consulting and licensing services. The Company has agreed to
subcontract the day to day management of these four practices for eighty percent
of the net profits of the PA, subject to certain adjustments to a Michigan based
company owned by the PA owner resulting, in effect, in the acquisition of a
twenty percent interest. Costs associated with this subcontract are included in
General and Administrative. The Company will continue to receive license fees of
$40,000 per year.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
    BASIS OF PRESENTATION/BASIS OF CONSOLIDATION
 
    The accompanying consolidated financial statements have been prepared on the
accrual basis of accounting and include only those operations which are under
the ownership and financial control of the Company. All intercompany accounts
and transactions have been eliminated in consolidation. The Company's
predecessor subsidiaries were consolidated for the year ended 1995. The Company
does not have any ownership in or exercise control over the dentistry activities
of the PAs and accordingly, the accompanying financial statements do not
consolidate the results of the PAs.
 
    STOCK SPLIT
 
    On October 6, 1997 the Company's Board of Directors authorized a 81.54 to 1
stock split. The increase in authorized shares and the stock split have been
retroactively reflected in these financial statements. The Company also
authorized an increase of its authorized common shares to 50 million.
 
    REVENUE RECOGNITION
 
    The Company records its revenue in accordance with Management Agreements and
other consulting and licensing agreements further described in Note 3.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    ADVERTISING
 
    The costs of advertising, promotion and marketing, aggregating $14,437,
$42,272 and $29,502 for the years ended December 31, 1995, 1996 and 1997,
respectively, are expensed when incurred and are included in general and
administrative expenses.
 
    FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The estimated fair value of amounts reported in the financial statements
have been determined by using available market information and appropriate
valuation methodologies. The carrying value of all current assets and current
liabilities approximates fair value because of their short-term nature. The
carrying value of all non-current financial instruments are considered to
approximate fair value based upon current market rates and instruments with
similar risks and maturities.
 
    CASH AND CASH EQUIVALENTS
 
    The Company considers all highly liquid investments purchased with an
original maturity of three months or less to be cash equivalents.
 
    CONSULTING AND LICENSE FEES RECEIVABLE
 
    Consulting and license fees receivable represents amounts owed to the
Company from various PAs for consulting and license fees provided under
contracts. The Company reviews the collectibility of its receivables related to
consulting and license fees. This review is based upon the cash flow of the PAs
and the fair market value of the collateral of the assets of the PAs.
 
    MANAGEMENT FEE RECEIVABLE FROM PA
 
    Management fee receivable from PA consists of amounts owed to the Company
related to revenue recorded in accordance with Management Agreements and is
recorded based upon the net realizable value of patient accounts receivable of
the PAs. The Company reviews the collectibility of the patient accounts
receivable of the PAs and adjusts its management fee receivable accordingly.
 
    ADVANCES TO PAS
 
    Advances to PAs consist of receivables from PAs in connection with working
capital advances made to affiliated practices. The Company reviews the
collectibility of its receivables related to advances to PAs. This review is
based upon the cash flow of the PAs, and the fair market value of the collateral
of the assets of the PAs. Commencing August 1997, under terms of note agreements
such advances are repayable under terms calling for interest at 8 1/2%, adjusted
for any changes in the Company's borrowing rate, and are due within 12 months of
issuance. All advances and payables between PAs under common ownership have a
right of offset included in the agreement. The Company has established a reserve
for these advances of $86,000 as of December 31, 1997.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    NOTES RECEIVABLE FROM PAS
 
    Notes receivable from PAs relate to financing of capital additions made by
PAs covering certain medical and non-medical assets. Notes receivable from PAs
generally have terms of 2 to 10 years, are interest bearing with rates between
8 1/2% and 18 1/2%, and are secured by the assets of the Managed Dental Center
and personally guaranteed by the PA owners.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost. Expenditures for maintenance and
repairs are charged to expenses as incurred and expenditures for additions and
betterments are capitalized. The cost of assets sold or otherwise disposed of
and the related accumulated depreciation are eliminated from the accounts and
any resulting gain or loss is reflected in the statement of operations.
 
    Depreciation is computed by using the straight-line method over the
estimated useful life of the asset, ranging from 3 to 10 years. Leasehold
improvements are amortized over their estimated useful life or the remaining
lease period, whichever is less.
 
    INTANGIBLE ASSETS
 
    Intangible assets includes certain organizational costs associated with the
incorporation of the Company and costs related to consideration given to
entities in exchange for (i) entering into Management Agreements, (ii) waiver by
minority stockholder of any rights to receive management fees under certain
Management Agreements, (iii) revised terms to existing Management Agreements and
(iv) the purchase of minority stockholder rights in PM. Intangible assets are
being amortized over periods of 5 to 25 years.
 
    STOCK BASED COMPENSATION
 
    In October 1995 the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 123, Accounting for Stock-Based Compensation
("SFAS No. 123"), which is effective for fiscal years beginning after December
15, 1995. Under SFAS No. 123, the Company may elect to recognize stock-based
compensation expense based on the fair value of the awards or continue to
account for stock-based compensation under Accounting Principles Board Opinion
No. 25, Accounting for Stock Issued to Employees ("APB No. 25") and disclose in
the financial statements the effects of SFAS No. 123 as if the recognition
provisions were adopted. The Company has elected to continue to account for its
stock based compensation for employees under APB No. 25 and adopt the disclosure
only requirements of SFAS No. 123. The Company has adopted a stock based
compensation plan for certain non-employees which are accounted for under SFAS
No. 123.
 
    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 amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

    The Company receives fees for services provided to the PAs under Management
Agreements, and Consulting and Licensing Agreements, but does not employ
dentists or control the practices of the dentists employed by the PAs. The
Company's revenue is dependent on revenue generated by the PAs and, therefore,
effective and continued performance of the Managed Dental Centers during the
term of the Management Agreements is essential to the Company's long-term
success.
 
    The Management Agreements are generally for a term of 25 years beginning on
the effective date of each individual agreement and renewing each and every year
on the anniversary date of the subsequent year for a period of generally 25
years and may be terminated by the PA, or the Company, under certain events of
default "with cause" as defined, including a material default by or bankruptcy
of the Company. In the event of a material default by the PA, or its owner, the
PA can sell the practice to a third party mutually agreed to or sell its assets
to the Company for a preset formula price and assign ownership interest to a PA
agreeable to all parties. In the event that the proper notification period is
given to the Company, the PA can terminate the agreement at any time without
cause if it sells the practice and assigns the agreement to another party to be
approved by the Company. The sales price in such event will be determined
through negotiations among the selling PA and the buyer. In no event can the
Company replace the PA at will or for a nominal fee, except in the event of
default. Any material loss of revenue by the PAs would have a material adverse
effect on the Company, including the PAs' ability to repay their indebtedness to
the Company.
 
    IMPAIRMENT OF ASSETS
 
    Statement of Financial Accounting Standards No. 121, Accounting for the
Impairment of Long-lived Assets and for Long-lived Assets to be Disposed of
("SFAS No. 121"), was implemented by the Company in fiscal 1996. SFAS No. 121
states that if the carrying value of a long-lived asset, including associated
intangibles, exceeds the sum of the estimated undiscounted cash flows from the
operation of the asset, an impairment loss should be recognized for the
difference between the asset's estimated fair value and carrying value. The
Company periodically analyzes its financial position with regards to the
provisions of SFAS No. 121. The Company evaluates whether events and
circumstances have occurred that indicate the carrying amount of these
long-lived assets may be impaired, by comparison of undiscounted cash flows from
operations with related carrying value of the assets. At December 31, 1997, the
unamortized balance of these assets are not considered to be impaired.
 
    ADOPTION OF NEW ACCOUNTING STANDARDS
 
    In February, 1997, the Financial Accounting Standards Board issued Statement
No. 128, Earnings Per Share ("SFAS No. 128"), which requires companies to change
in fiscal 1997 the way that they calculate and present earnings per share. In
accordance with those requirements, the Company now presents "basic" earnings
per share, which is net income divided by weighted average shares outstanding
during the period, and "diluted" earnings per share, which considers the impact
of common stock equivalents. The Company's common stock equivalents consist of
employee and director stock options and warrants to purchase common stock.
Earnings per share presented for prior periods have been restated in accordance
with SFAS 128.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    In June 1997, the FASB adopted two standards: SFAS Nos. 130 and 131,
Reporting Comprehensive Income and Disclosures about Segments of an Enterprise
and Related Information, respectively. Both of these new standards relate to the
presentation of financial information and do not impact the computation of net
income of earnings per share. Both will be effective for the Company beginning
with its 1998 annual financial statements. SFAS 130 requires that companies
display "comprehensive income", which in addition to the current definition of
net income includes certain amounts currently recorded directly in equity. SFAS
131 mandates the management approach to identifying business segments. Under the
management approach, segments are defined as the organizational units that have
been established for internal performance evaluation purposes. Management does
not believe that the new standard will impact its current presentation.
 
    INCOME TAXES
 
    Upon its incorporation on October 23, 1996, as described in Note 1, the
Company terminated its predecessor status as a Limited Liability Corporation and
is now subject to federal income taxes. Effective October 25, 1996, the Company
accounted for income taxes under the liability method in accordance with
Statement of Financial Accounting Standards No. 109, Accounting for Income Taxes
("SFAS No. 109").
 
3. REVENUE RECOGNITION
 
    MANAGEMENT FEES
 
    Management fees represent revenue earned from managed dental practices less
amounts retained by the practices for those PAs where the Company provides
management services.
 
    The Company earns management fees from the PAs under two types of contracts:
net revenue and net profits. Under the net revenue contracts, management fees
are equal to 67%-74% of the patient revenues earned by the PA. Such contracts
also stipulate that the Company must pay certain expenses, as defined by the
Management Agreement. Under the net profits contracts, management fees are equal
to between 50% and 55% of the practice's net profits, as defined. Net profit is
calculated by subtracting practice expenses (which constitutes both dental and
non-dental expenses), excluding depreciation and amortization, from net
collected practice revenue. Contractual revenues and related expenses have, for
purposes of the accompanying financial statements, been reflected on an accrual
basis.
 
    The amounts contractually retained by the practices under net revenue
contracts are intended to cover amounts incurred for (1) salary and benefits to
employ the dentists, hygienists and contracted specialists; (2) licensing fees
to be paid to the Company; (3) debt and asset carrying costs on the acquisition
of the practices; and (4) any other direct costs to the PA not covered under the
Management Agreement.
 
    The revised structure of the PA contracts is designed to provide the PA with
the opportunity to achieve profits over the term of the contract, as well as for
incentives for the PA owners and dental professionals to increase productivity
and the number of patient encounters, to improve the documentation of their
services so that appropriate billings can be rendered and to increase the
opportunity for dental professionals other than dentists to provide services.
 
    Effective October 1996, the Company revised the terms of all of its 12 then
existing Management Agreements such that the Company is responsible for the
payment of all non-professional expenses of the

Managed Dental Centers. Ten Management Agreements were also revised to base the
Company's management fee from a percentage of net profits at each PA to a
percentage of net revenue from each PA and two Management Agreements were
modified to assign additional responsibilities to the Company. Accordingly,
prior to the revision of these 12 Management Agreements, all non-professional
expenses of the Managed Dental Centers and related revenues were reflected in
each PAs financial statements. The Company expects to primarily utilize net
revenue contracts in the future.
 
    The PA located in Port Charlotte, Florida, has the right to terminate its
Management Agreement during a 90-day period beginning in October 1998. Such
Managed Dental Center contributed approximately 8% and 18% to the Company's
revenue in 1997 and 1996, respectively. The Management Agreement expires in
2003.
 
    The following table sets forth the gross practice revenue earned and amounts
retained by the PAs, and the management fees earned by the Company for the
periods ended:

11. MANDATORILY REDEEMABLE PREFERRED STOCK AND COMMON STOCK
 
    MANDATORILY REDEEMABLE PREFERERED STOCK
 
    On October 25, 1996, the Company executed a subscription agreement which
provided for the issuance of $1.5 million (15,000 shares at $100/share) in
mandatorily redeemable preferred stock. Under the terms of that agreement,
$500,000 of preferred stock was issued on October 25, 1996 and $1,000,000 was
issued on December 31, 1996. Proceeds of this issuance are reflected net of
$105,000 of related offering costs paid under the Advisory Agreement described
in Note 14.

11. MANDATORILY REDEEMABLE PREFERRED STOCK AND COMMON STOCK (CONTINUED)
 
    The Company had authorized 15,000 shares of Series A Convertible Preferred
Stock with a par value of $0.01 per share. The preferred stock accrued
cumulative dividends at $8/share, had voting and preemptive rights, adjustments
for dilutive effects and liquidation preferences equal to $100/share plus
accrued unpaid dividends. Dividends were payable in cash or, at holders' option,
one-half in cash and one-half in common stock. Upon consummation of the
Company's initial public offering on November 4, 1997, the preferred stock was
converted into common stock.
 
    COMMON STOCK WITH PUT RIGHTS
 
    In January 1994, GCH sold to a third party an owners interest equivalent to
13%. In connection with the sale of this owners interest, the owner became a
director of the Company and the Company attached certain put rights which are
exercisable after January 1, 2001, if the Company had not completed a public
offering of its common stock by that date. The per share price applicable to the
"put rights" is 6 times pre-tax net income for the calendar year immediately
preceding the exercise of the put times the ownership percentage that will be
put back to the Company.
 
    Concurrent with the Reorganization, this ownership interest was converted to
530,010 shares of common stock of the Company with put rights which are
equivalent to those described above. As of December 31, 1996, the redemption
value of these put rights has been reclassified to temporary equity, from
permanent equity on the Company's balance sheet. Upon consummation of the
Company's initial public offering on November 4, 1997, the put rights provisions
were eliminated.
 
12. EMPLOYEE BENEFITS
 
    On January 26, 1994 and October 25, 1996, the Company issued to one of its
officers warrants to purchase 81,540 shares of stock (at each grant date), with
an exercise price at the then fair market value (aggregate value of $147,768 and
$125,000 respectively) of the stock, as determined by an independent third party
appraisal. The warrants became fully vested in January 1997. All such warrants
were exercised in February 1997, and the exercise price was funded by an
interest bearing note from the Company. This interest bearing note has been
offset against additional paid-in capital in stockholders' equity at December
31, 1997.
 
    On January 21, 1997, the Company issued a stock option for 49,576 shares of
stock to another officer of the Company which are exercisable, in whole or in
part, immediately. Exercise price is fair market value on the grant date ($1.53
per share). In no event shall this option be exercisable after January 21, 2002.
 
    In November 1997, the Company adopted the 1997 Executive Incentive
Compensation Plan (the "Incentive Plan") which is designed to attract and retain
employees, officers and directors. The Incentive Plan is administered by the
Stock Option and Compensation Committee of the Board of Directors and 250,000
shares of common stock have been reserved for the Incentive Plan.
 
    Concurrent with the adoption of the Incentive Plan, the Company issued stock
options for 61,500 shares to its employees. The options vest over a period of 3
to 5 years and must be exercised by February 2003. Exercise price is fair market
value on grant debt ($12.00 per share). Currently any shares issued upon
exercise would be unregistered. The Company expects to register the shares
underlying the Incentive Plan before the shares issued in November, 1997 become
exercisable.

    Pro forma information regarding net income and earnings per share is
required by SFAS No. 123, and has been determined as if the Company had
accounted for its employee stock options under the fair value method of SFAS No.
123. The fair value of each option grant is estimated on the date of grant using
the fair value method with the following weighted average assumptions: no
dividend yield, 11% expected volatility, risk-free interest rates ranging from
5.80% and average expected lives of four years.
 
    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options. For purposes of pro
forma disclosures, the estimated fair value of the

    Because the SFAS No. 123 provides for pro forma amounts for options granted
beginning in 1995, the pro forma expense will likely increase in future years as
the new option grants become subject to the pricing model.
 
    For periods prior to the registration of the Company's common stock,
independent valuations were utilized to determine the value of the common stock.
 
13. NON-EMPLOYEE OPTION PLAN AND WARRANTS
 
    In November 1997, the Company adopted the 1997 Non-qualified Stock Option
Plan ("Non-employee Plan") which is designed to provide additional incentives
for the PAs with which the Company has entered into management agreements to
attract and retain qualified dentists, health care specialists and PA owners.
The Non-employee Plan is administered by the Stock Option and Compensation
Committee of the Board of Directors and 425,000 shares of Common Stock have been
reserved for the Non-employee Plan.
 
    Concurrent with the adoption of the Non-employee Plan, the Company issued
stock options for 124,000 shares. The options vest over a period of 3 to 5 years
and must be exercised by February 2003. Exercise price is fair market value on
the grant date ($12.00 per share). Currently any shares issued would be
unregistered. The Company has not yet determined whether the shares underlying
the Non-employee Plan will be registered.
 
    In conjunction with work performed under the Advisory Agreement (Note 14),
the Company also granted warrants to advisors.

    The fair value of each option grant is estimated on the date of grant using
the fair value method with the following weighted average assumptions: no
dividend yield, 11% expected volatility, risk-free interest rates ranging from
5.80% and average expected lives of four years.
 
    The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's non-employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its non-employee stock options. For purposes
of expense recognition, the estimated fair value of the options is amortized to
expense over the options' vesting period.
 
    The Company recorded expense associated with the grant of options and
warrants totaling $15,993, $0, and $39,769, for the years ending December 31,
1995, 1996, and 1997, respectively.

15. EARNINGS PER SHARE (CONTINUED)
    Options to purchase 81,540 shares of Common Stock at $1.81 per share, which
were outstanding since October 1994 were not included in the computation of
diluted earnings per share for 1995 or 1996 because the options' exercise price
was greater than the average market price of the common shares. These options
were exercised in 1997.
 
    PRO FORMA
 
    Upon its incorporation on October 23, 1996, as described in Note 1, the
Company terminated its predecessor status as a limited liability corporation and
became subject to federal and state income taxes. In addition, due to the
conversion of the preferred stock into common stock and the termination of the
common stock put rights concurrent with the closing of the initial public
offering, pro forma net income per share is computed using the pro forma net
income of the Company before deductions for the adjustment in redemption value
of the common and preferred securities and preferred stock dividends. Since the
Company has adopted Financial Accounting Standards Board Statement No. 128
"Earnings per Share" in 1997, pro forma adjustments for income taxes as if the
Company had been treated as a C corporation and the impact of the preferred
stock comversion have not been included in historical earnings per share in the
Statement of Operations. Had the Company not restated prior years' earnings per
share, the pro forma effect would have been as follows:

(1) BUSINESS DESCRIPTION
 
   
    Capitol Dental Care, Inc. (CDC), an Oregon Corporation, is a dental care
    organization that contracts with the State of Oregon Office of Medical
    Assistance Program (OMAP) to provide care under the Oregon Health Plan
    (OHP). The combined companies derived 95% and 93% of their revenues from the
    State of Oregon for the years ended December 31, 1997 and 1996,
    respectively. CDC in turn contracts with dental care providers, including
    Dental Maintenance of Oregon, P.C. (DMO), a subchapter S Corporation
    incorporated in the state of Oregon. DMO has 9 clinics throughout Oregon and
    employs approximately 15 dentists to provide dental care to OHP participants
    and to non-participants in the OHP on a fee-for-service basis. CDC and DMO
    are related through common ownership. Accordingly, the financial statements
    of CDC and DMO are combined.

    (B) CAPITATION AND OTHER REVENUE
 
   
       Capitation and other revenue represents the premiums received from OMAP
       for related OHP participants and revenue from dental services provided
       for commercially insured and private pay patients, reported at estimated
       realizable amounts net of contractual adjustments. Capitation revenue is
       recognized ratably over the period covered. Dental service revenue is
       recognized as earned, as services are rendered. The combined companies
       derived approximately 95% and 93% of their revenues from OMAP for the
       years ended December 31, 1997 and 1996 respectively.

    (F) INTANGIBLE ASSETS AND START-UP COSTS
 
       Intangible assets result primarily from the amount of purchase price for
       dental practices in excess of the fair market value of the net assets
       acquired. The amounts are amortized on the straight-line basis over
       fifteen years. Amortization expense was $1 for the years ended December
       31, 1997 and 1996.
 
       Preoperating and start-up costs incurred in connection with the creation
       of new dental clinics are capitalized until such facilities become
       operational. These costs are then amortized on the straight-line basis
       over a five-year period. Amortization expense was $6 for the years ended
       December 31, 1997 and 1996.
 
       During 1996, the Company adopted Statement of Financial Accounting
       Standards Number 121 "Accounting for the Impairment of Long-lived Assets
       and for Long-lived Assets to be Disposed of." The Company reviews its
       asset balances for impairment at the end of each year or more frequently
       when events or circumstances indicate that the carrying amount of
       long-lived assets may not be recoverable. To perform this review, the
       Company estimates the expected future undiscounted net cash flows to be
       derived from the use of the related asset. If the estimated net cash
       flows are less than the carrying amount of the long-lived asset, the
       Company recognizes an impairment loss in an amount necessary to write
       down the long-lived asset to fair value as

(2) SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
       determined from the expected future discounted cash flows. No write-down
       for impairment loss was recorded for the year ended December 31, 1997.
 
    (G) FAIR VALUE OF FINANCIAL INSTRUMENTS
 
       The Company estimates the fair value of its monetary assets and
       liabilities based upon the existing interest rates related to such assets
       and liabilities compared to current market rates of interest for
       instruments with a similar nature and degree of risk. The Company
       estimates that the carrying value of all its monetary assets and
       liabilities approximates fair value as of December 31, 1997.
 
    (H) 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,
       including incurred but not reported claims, disclosure of contingent
       assets and liabilities at the date of the financial statements and the
       reported amounts of revenues and expenses during the reporting period.
       Actual results could differ from those estimates.
    
 
    (I) RESTRICTED CASH
 
       The Company is contractually required to maintain a minimum of $250 in a
       segregated cash account for use only in the event of insolvency. A
       secondary amount is also required based on the average monthly fee for
       service liability from the prior quarter, which amounted to $280 and $32
       at December 31, 1997 and 1996, respectively.
 
   
    (J) ACCRUED CLAIMS INCURRED BUT NOT REPORTED
    
 
   
       The Company records an estimate for the cost of participant claims based
       on historical experience.
    
 
   
    (K) NEW PRONOUNCEMENTS
    
 
       In April 1998, the Accounting Standards Executive Committee issued
       Statement of Position ("SOP") No. 98-5, "Reporting on the Costs of
       Start-up Activities," which is effective for fiscal years beginning after
       December 15, 1998. The SOP provides guidance on the financial reporting
       of start-up activities and organizational costs. It requires costs of
       start-up activities and organizational costs to be expensed when incurred
       and, upon adoption, the write off as a cumulative effect of a change in
       accounting principle any previously capitalized start-up or
       organizational costs. The Company plans to adopt the provisions of SOP
       98-5 in the first quarter of 1999. The carrying amount of such costs were
       approximately $20 as of December 31, 1997.
 
(3) MALPRACTICE INSURANCE
 
    The Company's dentists are insured with respect to dentistry malpractice
    risks on a claims-made basis. Management is not aware of any claims or
    incidents that may result in the assertion of a claim. However, there may be
    claims from unknown incidents that may be asserted arising from services
    provided to patients. Management is not aware of any claims against the
    Company or its affiliated

    position or results or operations.

corporation ("PARENTCO"), Wisdom Holdings Acquisition Corp. I, a Delaware
corporation and wholly owned subsidiary of ParentCo ("GDSC MERGER SUB"), Wisdom
Holdings Acquisition Corp. II, a Delaware corporation and wholly owned
subsidiary of ParentCo ("DCA MERGER SUB"), Gentle Dental Service Corporation, a
Washington corporation ("GDSC"), and Dental Care Alliance, Inc., a Delaware
corporation ("DCA").
 
                                    RECITALS
 
    A.  GDSC is a Washington corporation, having its principal place of business
in El Segundo, California. GDSC provides dental practice management and related
services to dental practices in the States of California, Florida, Hawaii,
Idaho, Oregon and Washington.

    C.  Each of ParentCo, GDSC Merger Sub and DCA Merger Sub is a newly formed
Delaware corporation created to accomplish the business combinations by and
between GDSC and DCA as described in this Agreement. At the Effective Time of
the Merger (as each of those terms is defined below), the outstanding shares of
capital stock of GDSC and DCA, respectively, shall be converted into the right
to receive shares of capital stock of ParentCo (as provided herein). As a
result, the stockholders of GDSC and DCA, respectively, shall become the
stockholders of ParentCo and both GDSC and DCA shall become and continue to
conduct their respective businesses and operations as wholly owned subsidiaries
of ParentCo. The transactions described in this Agreement are subject to the
approval of the stockholders of GDSC and DCA, respectively, and the satisfaction
of certain other conditions described in this Agreement.
 
    D.  It is the intention of the parties to this Agreement that the business
combinations contemplated hereby be accounted for under the
"pooling-of-interests" accounting method and be treated as (i) "reorganizations"
under Section 368 of the Internal Revenue Code of 1986, as amended (the "CODE")
or (ii) a transfer to a controlled corporation qualifying under Section 351 of
the Code.
 
    E.  The respective Boards of Directors of each of GDSC and DCA have
determined that it is in the best interests of their respective companies and
their stockholders to consummate the strategic business combination transaction
provided for herein.
 
                                   AGREEMENT

                                   ARTICLE II
               MERGER CONSIDERATION; MANNER OF CONVERTING SHARES
 
    2.1.  MERGER CONSIDERATION.  Subject to the provisions of this Agreement, at
the Effective Time, automatically by virtue of the Merger and without any action
on the part of any Person, the shares of the constituent corporations shall be
converted as follows (collectively, "MERGER CONSIDERATION"):
 
    (a) Each share of GDSC Merger Sub Common Stock issued and outstanding at the
Effective Time shall cease to be outstanding and shall be converted into one
share of GDSC Common Stock.
 
    (b) Each share of DCA Merger Sub Common Stock issued and outstanding at the
Effective Time shall cease to be outstanding and shall be converted into one
share of DCA Common Stock.
 
    (c) Each share of GDSC Common Stock (including any and all shares of
restricted GDSC Common Stock, Performance Shares or earnout shares, all of which
are described in the GDSC Disclosure Schedules) issued and outstanding at the
Effective Time shall cease to be outstanding and shall be converted into and
exchanged for one share of ParentCo Common Stock.
 
    (d) Each share of DCA Common Stock issued and outstanding at the Effective
Time shall cease to be outstanding and shall be converted into and exchanged for
1.67 shares of ParentCo Common Stock.
 
    (e) Each share of GDSC Series A Preferred Stock shall cease to be
outstanding and shall be converted into and exchanged for the right to receive
one share of ParentCo Series A Preferred Stock.
 
    (f) Each share of GDSC Series B Preferred Stock shall cease to be

    (g) Each share of GDSC Series C Preferred Stock shall cease to be

Series C Preferred Stock.
 
    (h) Each share of GDSC Series D Preferred Stock shall cease to be
outstanding and shall be converted into and exchanged for one share of ParentCo
Series D Preferred Stock.
 
    2.2.  DISSENTING STOCKHOLDERS.  Any Dissenting Stockholder who shall be
entitled to be paid the "fair value" of his or her Dissenters' Shares shall not
be entitled to the Merger Consideration as set forth in SECTION 2.1 in respect
thereof unless and until such Dissenting Stockholder shall have failed to
perfect or shall have effectively withdrawn or lost such Dissenting
Stockholder's right to dissent from the Merger under the WBCA and shall be
entitled to receive only the payment provided for by Chapter 23B.13 of the WBCA
with respect to such Dissenters' Shares. Upon the payment by the ParentCo of the
"fair value" of any Dissenters' Shares in accordance with Chapter 23B.13 of the
WBCA, such Dissenters' Shares shall be canceled and retired and shall cease to
exist, and no exchange or further payment shall be made with
respect thereto. If any Dissenting Stockholder shall fail to perfect or shall
have effectively withdrawn or lost such right to dissent, the Dissenters' Shares
held by such Dissenting Stockholder shall thereupon be treated as though such
Dissenters' Shares had been converted into the right to receive the Merger
Consideration as set forth in the applicable provision of SECTION 2.1.
 
    2.3.  RIGHTS AS STOCKHOLDERS; STOCK TRANSFERS.  At the Effective Time,
holders of GDSC Common Stock and DCA Common Stock shall cease to be, and shall
have no rights as, stockholders of GSDC or DCA, other than to receive any
dividend or other distribution with respect to such GSDC Common Stock or DCA
Common Stock with a record date occurring prior to the Effective Time and the
consideration provided under this ARTICLE II. After the Effective Time, there
shall be no transfers on the stock transfer books of GDSC, DCA or the Surviving
Corporations of shares of GDSC Common Stock or DCA Common Stock outstanding
prior to the Effective Time.
 
    2.4.  FRACTIONAL SHARES.  Notwithstanding any other provision hereof, no
fractional shares of ParentCo Capital Stock and no certificates or scrip
therefor, or other evidence of ownership thereof, will
 
                                      A-4
<PAGE>
be issued in the Merger; instead, ParentCo shall pay to each holder of either
GDSC Common Stock or DCA Common Stock who would otherwise be entitled to a
fractional share of ParentCo Capital Stock (after taking into account all Old
GDSC Certificates or Old DCA Certificates delivered by such holder) an amount in
cash (without interest) determined by multiplying the fraction of a share by the
average of the closing prices of GDSC reported on Nasdaq for the five
consecutive trading days immediately preceding the date of the Effective Time.
 
    2.5.  ANTI-DILUTION PROVISIONS.  In the event either GDSC or DCA changes (or
establishes a record date for changing) the number of shares of GDSC Common
Stock or DCA Common Stock issued and outstanding prior to the Effective Date as
a result of a stock split, stock dividend, recapitalization or similar
transaction with respect to the outstanding GDSC Common Stock or DCA Common
Stock and the record date therefor shall be prior to the Effective Date, the
number of shares of ParentCo Capital Stock the holders of GDSC Common Stock and
DCA Common Stock or options exercisable for same shall be entitled to receive
under this Agreement shall be proportionately adjusted.
 
    2.6.  CONVERSION OF RIGHTS.
 
    (a) At the Effective Time, each option or other right to purchase shares of
either GDSC Common Stock or DCA Common Stock pursuant to stock options or stock
appreciation rights ("GDSC OPTIONS" or "DCA OPTIONS") granted by GDSC under the
GDSC Stock Plans or DCA under the DCA Stock Plans and outstanding at the
Effective Time, whether or not exercisable, and all other warrants or other
rights to purchase shares of GDSC Common Stock or DCA Common Stock (together
with the GDSC Options or the DCA Options, the "GDSC RIGHTS" or the "DCA
RIGHTS"), shall be converted into and become rights with respect to ParentCo
Common Stock, and ParentCo shall assume each GDSC Right and DCA Right, in
accordance with the terms of the GDSC Stock Plan or the DCA Stock Plan or such
other agreement or arrangement pertaining to such GDSC Rights or DCA Rights (as
applicable), except that from and after the Effective Time, (i) ParentCo and its
Compensation Committee shall be substituted for the GDSC Board and the DCA Board
or the committee of the GDSC Board and the DCA Board administering the GDSC
Stock Plan or the DCA Stock Plan, (ii) each GDSC Right and DCA Right assumed by
ParentCo may be exercised only for shares of ParentCo Common Stock (or cash, in
the case of the stock appreciation rights), (iii) the number of shares of
ParentCo Common Stock subject to GDSC Rights or DCA Rights shall be equal to the
number of shares of GDSC Common Stock or DCA Common Stock subject to the GDSC
Right or the DCA Right immediately prior to the Effective Time multiplied by the
GDSC Exchange Ratio or the DCA Exchange Ratio, as the case may be, and (iv) the
per share exercise price under either the GDSC Right or the DCA Right shall be
adjusted by dividing the per share exercise price under the GDSC Right or the
DCA Right by the GDSC Exchange Ratio or the DCA Exchange Ratio, as the case may
be, and rounding up to the nearest cent. Notwithstanding the provisions of
clause (iii) of the preceding sentence, ParentCo shall not be obligated to issue
any fraction of a share of ParentCo Common Stock upon exercise of a GDSC Right
or a DCA Right. Any fraction of a share of ParentCo Common Stock that otherwise
would be subject to a converted GDSC Right or DCA Right shall represent the
right to receive cash payment upon exercise of such converted GDSC Right or DCA
Right equal to the product of such fraction and the difference between the
market value of one share of ParentCo Common Stock at the time of exercise of
such Right and the per share exercise price of such Right. The term,
exercisability, vesting schedule, status as an "Incentive Stock Option" under
Section 422 of the Code, if applicable, and all other terms and conditions of
the options or warrants, to the extent permitted by law, and otherwise
reasonably practical shall be unchanged; each option which is an Incentive Stock
Option shall be adjusted in accordance with the requirements of Section 424(a)
of the Code so as not to constitute a modification, renewal or extension of the
option within the meaning of Section 424(h) of the Code.
 
    (b) Each of GDSC and DCA agree to take all necessary steps to effectuate the
foregoing provisions of this SECTION 2.6, including using its reasonable efforts
to obtain from each holder of a GDSC Right or DCA Right any consent or agreement
that may be deemed necessary or advisable in order to effectuate
 
                                      A-5
<PAGE>
the transactions contemplated by this SECTION 2.6. Anything in this Agreement to
the contrary notwithstanding, ParentCo shall have the right, in its sole
discretion, not to deliver the consideration provided in this SECTION 2.6 to a
former holder of a GDSC Right or a DCA Right who has not delivered such consent
or agreement.
 
                                  ARTICLE III
                               EXCHANGE OF SHARES
 
    3.1.  EXCHANGE PROCEDURES.
 
    (a) At or prior to the Effective Time, ParentCo shall deposit, or shall
cause to be deposited, with such bank, trust company or transfer agent as
ParentCo shall elect (in such capacity, the "EXCHANGE AGENT"), for the benefit
of the holders of certificates formerly representing shares of either GDSC
Common Stock or GDSC Preferred Stock (collectively, "OLD GDSC CERTIFICATES") or
DCA Common Stock ("OLD DCA CERTIFICATES"), for exchange in accordance with
ARTICLE II, certificates representing the shares of ParentCo Capital Stock ("NEW
CERTIFICATES") and an estimated amount of cash (such cash and New Certificates,
together with any dividends or distributions with a record date occurring after
the Effective Date with respect thereto, without any interest on any such cash,
dividends or distributions, being hereinafter referred to as the "EXCHANGE
FUND") to be paid pursuant to ARTICLE II in exchange for outstanding shares of
GDSC Common Stock, GDSC Preferred Stock or DCA Common Stock.
 
    (b) As soon as practicable after the Effective Date, ParentCo shall send or
cause to be sent to each former holder of record of shares of GDSC Common Stock,
GDSC Preferred Stock or DCA Common Stock immediately prior to the Effective Time
transmittal materials for use in exchanging such stockholder's Old GDSC
Certificates or Old DCA Certificates for the consideration set forth in ARTICLE
II, which transmittal materials both GDSC and DCA shall have had the opportunity
to review prior to the Effective Date. ParentCo shall cause the New Certificates
and any check in respect of any fractional share interests or dividends or
distributions which the holder of such shares shall be entitled to receive upon
delivery to the Exchange Agent of Old GDSC Certificates or Old DCA Certificates
representing such shares (or an affidavit of lost certificate and, if required
by the Exchange Agent, indemnity reasonably satisfactory to ParentCo and the
Exchange Agent, if any of such certificates are lost, stolen or destroyed) owned
by such stockholder. No interest will be paid on any such cash to be paid in
lieu of fractional share interests or in respect of dividends or distributions
which any such person shall be entitled to receive pursuant to ARTICLE II upon
such delivery. In the event of a transfer of ownership of any shares of GDSC
Common Stock, GDSC Preferred Stock or DCA Common Stock not registered in the
transfer records of either GDSC or DCA, the exchange described in this SECTION
2.1(B) may nonetheless be effected and a check for the cash to be paid in lieu
of fractional shares may be issued to the transferee if the Old GDSC Certificate
or Old DCA Certificate is presented to the Exchange Agent, accompanied by
documents sufficient, in the discretion of ParentCo and the Exchange Agent, (i)
to evidence and effect such transfer but for the provisions of SECTION 2.3
hereof and (ii) to evidence that all applicable stock transfer taxes have been
paid.
 
    (c) If either Old GDSC Certificates or Old DCA Certificates are not
surrendered or the consideration therefor is not claimed prior to the date on
which such consideration would otherwise escheat to or become the property of
any governmental unit or agency, the unclaimed consideration shall, to the
extent permitted by abandoned property and any other applicable law, become the
property of the Surviving Corporations (and to the extent not in its possession
shall be paid over to the Surviving Corporations), free and clear of all claims
or interest of any person previously entitled to such claims. Notwithstanding
the foregoing, neither the Exchange Agent nor any party hereto shall be liable
to any former holder of either GDSC Common Stock, GDSC Preferred Stock or DCA
Common Stock for any amount properly delivered to a public official pursuant to
applicable abandoned property, escheat or similar laws.
 
                                      A-6
<PAGE>
    (d) At the election of ParentCo, no dividends or other distributions with
respect to ParentCo Common Stock with a record date occurring after the
Effective Time shall be paid to the holder of any unsurrendered Old GDSC
Certificate or Old DCA Certificate or options for same converted in the Merger
into the right to receive shares of such ParentCo Common Stock until the holder
thereof shall be entitled to receive New Certificates in exchange therefor in
accordance with the procedures set forth in this SECTION 3.1. After becoming so
entitled in accordance with this SECTION 3.1, the record holder thereof also
shall be entitled to receive any such dividends or other distributions, without
any interest thereon, which theretofore had become payable with respect to
shares of ParentCo Capital Stock such holder had the right to receive upon
surrender of the Old GDSC Certificate or Old DCA Certificate.
 
    (e) Any portion of the Exchange Fund that remains unclaimed by the
stockholders of either GDSC or DCA for six months after the Effective Time shall
be returned by the Exchange Agent to ParentCo. Any stockholders of GDSC or DCA
who have not theretofore complied with this ARTICLE III shall thereafter look
only to ParentCo for payment of the shares of ParentCo Capital Stock, cash in
lieu of any fractional shares and unpaid dividends and distributions on ParentCo
Capital Stock deliverable hereunder, in each case, without any interest thereon.
 
                                   ARTICLE IV
                     REPRESENTATIONS AND WARRANTIES OF GDSC
 
    On or prior to the date hereof, GDSC has delivered to DCA schedules ("GDSC
DISCLOSURE SCHEDULES") setting forth, among other things, items the disclosure
of which is necessary or appropriate either in response to an express disclosure
requirement contained in a provision hereof or as an exception to one or more
representations or warranties contained in this ARTICLE IV; provided, that (i)
no such item is required to be set forth in the GDSC Disclosure Schedules as an
exception to a representation or warranty if its absence would not be reasonably
likely to result in the related representation or warranty being deemed untrue
or incorrect under the standard established in the subsequent sentence, and (ii)
the mere inclusion of an item in the GDSC Disclosure Schedules as an exception
to a representation or warranty shall not be deemed an admission by a party that
such item represents a material exception or fact, event or circumstance or that
such item is reasonably likely to result in a Material Adverse Effect. No
representation or warranty of GDSC contained in this ARTICLE IV shall be deemed
untrue or incorrect, and no party hereto shall be deemed to have breached a
representation or warranty, as a consequence of the existence of any fact, event
or circumstance unless such fact, circumstance or event, individually or taken
together with all other facts, events or circumstances inconsistent with any
representation or warranty contained in this ARTICLE IV has had or is reasonably
likely to have a Material Adverse Effect on the party making such representation
or warranty. The numbers set forth on the GDSC Disclosure Schedules correspond
to the particular Section number contained in the Agreement. Information or
disclosure provided with reference to one Section may also be responsive to
information or disclosure responsive to another Section. Therefore, if the
information or disclosure set forth in one Section can be reasonably determined
to apply to information or disclosure in another Section, such information or
disclosure shall constitute disclosure for all applicable Sections. GDSC agrees
that with respect to its representations and warranties, GDSC shall have the
right to supplement and amend the GDSC Disclosure Schedules with respect to any
events occurring after the date of this Agreement and prior to the Effective
Time which such new event or information, when scheduled, shall not constitute a
breach hereof. In the event any such supplement or amendment discloses new
events that are reasonably likely to have a Material Adverse Effect on GDSC or
on ParentCo, DCA shall have the right to terminate the Agreement pursuant to
SECTION 11.1(G).
 
    Subject to the preceding paragraph and except as Previously Disclosed in a
paragraph of the GDSC Disclosure Schedules corresponding to the relevant
paragraph below, GDSC hereby represents and warrants to DCA:

financial point of view.

    As of the date hereof, no shares of GDSC Common Stock were held in treasury
by GDSC or otherwise beneficially owned by GDSC or its Subsidiaries. The
outstanding shares of GDSC Common Stock and GDSC Preferred Stock have been duly

1998, there has been no adjustments of the Conversion Price as set forth in
Article XII, Section 6(c) to the Amendment to the Articles of Incorporation of
GDSC and the representation set forth therein is true and correct as of and on
May 15, 1998.

    4.4.  CORPORATE POWER.  GDSC and each of its Subsidiaries has the corporate
power and authority to carry on its business as it is now being conducted and to
own all its properties and assets; and GDSC has the corporate power and
authority to execute, deliver and perform its obligations under this Agreement
and to consummate the transactions contemplated hereby.
 
    4.5.  CORPORATE AUTHORITY.  Subject in the case of this Agreement to receipt
of the requisite approval of the agreement of merger set forth in this Agreement
by the holders of a majority of the outstanding shares of GDSC Common Stock and
GDSC Preferred Stock entitled to vote thereon, this Agreement and the
transactions contemplated hereby and thereby have been authorized by all
necessary corporate action of GDSC and the GDSC Board on or prior to the date
hereof. This Agreement is a valid and legally binding obligation of GDSC,

affecting creditors' rights or by general equity principles).

Governmental Authority or with any third party are required to be made or

the type described in SECTION 11.1(D).
 
    (b) Subject to receipt of the approvals referred to in the preceding
paragraph, and the expiration of related waiting periods, the execution,
delivery and performance of this Agreement and the consummation of the
transactions contemplated hereby and thereby do not and will not (i) constitute
a breach or violation of, or a default under, or give rise to any Lien, any
acceleration of remedies or any right of termination under, any law, rule or
regulation or any judgment, decree, order, governmental permit or license, or
agreement, indenture or instrument of GDSC or of any of its Subsidiaries or to
which GDSC or any of its Subsidiaries or properties is subject or bound, (ii)
constitute a breach or violation of, or a default under, the GDSC Articles or
the GDSC Bylaws, or (iii) require any consent or approval under any such law,

the applicable Governmental Authority with which they were filed. The GDSC SEC

applicable requirements of the Securities Act and the Exchange Act, as the case
may be, and (ii) did not at the time they were filed (or if amended or

such filing) contain any untrue statement of a material fact or omit to state a
material fact required to be stated in such GDSC SEC Reports or necessary in

    4.10.  COMPLIANCE WITH LAWS.
 
    (a) GDSC and each of its Subsidiaries:
 
        (i) is in material compliance with all applicable federal, state, local
    and foreign statutes, laws, regulations, ordinances, rules, judgments,
    orders or decrees applicable thereto or to the employees conducting such
    businesses;
 
        (ii) has all permits, licenses, authorizations, orders and approvals of,
    and has made all filings, applications and registrations with, all
    Governmental Authorities that are required in order to permit them to own or
    lease their properties and to conduct their businesses as presently
    conducted; all such permits, licenses, certificates of authority, orders and
    approvals are in full force and effect and, to GDSC's knowledge, no
    suspension or cancellation of any of them is threatened; and
 
       (iii) has not received, since December 31, 1997, any notification or
    communication from any Governmental Authority (a) asserting that GDSC or any
    of its Subsidiaries is not in compliance with any of the statutes,
    regulations or ordinances which such Governmental Authority enforces or (b)
    threatening to revoke any license, franchise, permit or governmental
    authorization (nor, to GDSC's knowledge, do any grounds for any of the
    foregoing exist).
 
    (b) The terms and conditions set forth in the management agreements between
GDSC or its Subsidiaries and the dental practices managed by such entities
comply in all material respects with applicable laws, rules, regulations and
other applicable authorities relating to such agreements, including but not
limited to laws, rules, regulations and other applicable authorities relating to
the corporate practice of dentistry, fee-splitting, kickbacks and patient
brokering and those relating to such practices.
 
    4.11.  MATERIAL CONTRACTS; DEFAULTS.  Neither GDSC nor any of its
Subsidiaries is a party to, bound by or subject to any agreement, contract,
arrangement, commitment or understanding (whether written or oral) (i) that is a
"material contract" within the meaning of Item 601(b)(10) of SEC Regulation S-K,
or (ii) that materially restricts the conduct of business by it or any of its
Subsidiaries that has not been filed with or incorporated by reference in
reports filed under either the Securities Act or the Exchange Act. Neither GDSC
nor any of its Subsidiaries is in material default under any material contract,
agreement, commitment, arrangement, lease, insurance policy or other material
instrument to which it is a party, by which its respective assets, business, or
operations may be bound or affected, or under which it or its respective assets,
business, or operations receives benefits, and there has not occurred any event
that, with the lapse of time or the giving of notice or both, would constitute
such a default.
 
    4.12.  NO BROKERS.  Except for commissions, fees and other like payments due
to Salomon Smith Barney, no action has been taken by GDSC that would give rise
to any valid claim against any party hereto for a brokerage commission, finder's
fee or other like payment with respect to the transactions contemplated by this
Agreement.
 
    4.13.  EMPLOYEE BENEFIT PLANS.
 
    (a) All benefit and compensation plans, contracts, policies or arrangements
covering current employees or former employees of GDSC and its Subsidiaries
(collectively, the "GDSC EMPLOYEES") and current or former directors of GDSC,
including, but not limited to, "employee benefit plans" within the meaning of
Section 3(3) of ERISA, and deferred compensation, stock option, stock purchase,
stock appreciation rights, stock based, incentive and bonus plans (collectively,
the "GDSC BENEFIT PLANS"), are Previously Disclosed. True and complete copies of
all GDSC Benefit Plans, including, but not limited to, any trust instruments and
insurance contracts forming a part of any GDSC Benefit Plans, and all amendments
thereto have been provided or made available to the other parties hereto.
 
    (b) All employee benefit plans, other than "multiemployer plans" within the
meaning of Section 3(37) of ERISA, covering GDSC Employees (the "GDSC PLANS"),
have been administered in all material respects in compliance with their terms
and with all applicable laws, [to the extent subject to
 
                                      A-11
<PAGE>
ERISA], including without limitation, ERISA and the Code. GDSC is not a party to
any "employee pension benefit plan" within the meaning of Section 3(2) of ERISA
("GDSC PENSION PLAN") and which is a defined benefit plan as defined in Section
3(35) of ERISA. With respect to the employee benefit plan intended to qualify
under Section 401 of the Code, the Internal Revenue Service has issued a
favorable determination letter, a true and correct copy of which has been
provided to DCA, that such plan is, and each such plan in fact is, qualified and
exempt from federal income taxes. There is no pending or, to the knowledge of
GDSC, threatened litigation relating to any GDSC Plan. There are no audits,
inquiries, reviews, proceedings, claims or demands pending with any governmental
or regulatory agency, and there are no facts which could give rise to any
material liability in the event of any such investigation, claim, action, suit,
audit, review or proceeding. Neither GDSC nor any of its Subsidiaries has
engaged in a transaction with respect to any GDSC Plan that, assuming the
taxable period of such transaction expired as of the date hereof, could subject
GDSC or any of its Subsidiaries to a tax or penalty imposed by either Section
4975 of the Code or Section 502(i) of ERISA.
 
    (c) No liability under Subtitle C or D of Title IV of ERISA has been or is
expected to be incurred by GDSC or any of its Subsidiaries with respect to any
ongoing, frozen or terminated "single-employer plan", within the meaning of
Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them,
or the single-employer plan of any entity which is considered one employer with
GDSC under Section 4001 of ERISA or Section 414 of the Code (a "GDSC ERISA
AFFILIATE"). Neither GDSC, any of its Subsidiaries nor an ERISA Affiliate has
contributed to a "multiemployer plan", within the meaning of Section 3(37) of
ERISA. No notice of a "reportable event", within the meaning of Section 4043 of
ERISA for which the 30-day reporting requirement has not been waived, has been
required to be filed for any GDSC Pension Plan or by any GDSC ERISA Affiliate
within the 12-month period ending on the date hereof or will be required to be
filed in connection with the transactions contemplated by this Agreement.
 
    (d) All contributions required to be made under the terms of any GDSC Plan
have been timely made or have been reflected on the consolidated financial
statements of GDSC included in the Regulatory Documents. Neither any GDSC
Pension Plan nor any single-employer plan of an ERISA Affiliate has an
"accumulated funding deficiency" (whether or not waived) within the meaning of
Section 412 of the Code or Section 302 of ERISA and no ERISA Affiliate has an
outstanding funding waiver. Neither GDSC nor any of its Subsidiaries has
provided, or is required to provide, security to any GDSC Pension Plan or to any
single-employer plan of a GDSC ERISA Affiliate pursuant to Section 401(a)(29) of
the Code.
 
    (e) Under each GDSC Pension Plan which is a single-employer plan, as of the
last day of the most recent plan year ended prior to the date hereof, the
actuarially determined present value of all "benefit liabilities", within the
meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the
actuarial assumptions contained in the GDSC Plan's most recent actuarial
valuation), did not exceed the then current value of the assets of such GDSC
Plan, and there has been no material change in the financial condition of such
GDSC Plan since the last day of the most recent plan year.
 
    (f) Neither GDSC nor any of its Subsidiaries has any obligations for retiree
health and life benefits under any GDSC Benefit Plan. GDSC or its Subsidiaries
may amend or terminate any such GDSC Benefit Plan at any time without incurring
any liability thereunder.
 
    (g) The consummation of the transactions contemplated by this Agreement will
not (i) entitle any employees of GDSC or any of its Subsidiaries to severance
pay, (ii) accelerate the time of payment or vesting or trigger any payment of
compensation or benefits under, increase the amount payable or trigger any other
material obligation pursuant to, any of the GDSC Benefit Plans or (iii) result
in any breach or violation of, or a default under, any of the GDSC Benefit
Plans. Without limiting the foregoing, as a result of the consummation of the
transactions contemplated by this Agreement, neither GDSC nor any of its
Subsidiaries will be obligated to make a payment to an individual that would be
a "parachute payment" to a "disqualified individual" as those terms are defined
in Section 280G of the Code, without regard to
 
                                      A-12
<PAGE>
whether such payment is reasonable compensation for personal services performed
or to be performed in the future.
 
    4.14.  LABOR MATTERS.  Neither GDSC nor any of its Subsidiaries is a party
to or is bound by any collective bargaining agreement, contract or other
agreement or understanding with a labor union or labor organization, nor is GDSC
or any of its Subsidiaries the subject of a proceeding asserting that it or any
such Subsidiary has committed an unfair labor practice (within the meaning of
the National Labor Relations Act) or seeking to compel GDSC or any such
Subsidiary to bargain with any labor organization as to wages or conditions of
employment, nor is there any strike or other labor dispute involving it or any
of its Subsidiaries pending or, to GDSC's knowledge, threatened, nor is GDSC
aware of any activity involving its or any of its Subsidiaries' employees
seeking to certify a collective bargaining unit or engaging in other
organizational activity.
 
    4.15.  YEAR 2000 COMPLIANCE.  Except as Previously Disclosed, (i) the
computer software and related hardware of GDSC and its Subsidiaries (the "GDSC
COMPUTER SYSTEM") used for the storage and processing of data are or will be
prior to the year 2000 Year 2000 Compliant; (ii) to the actual knowledge of
GDSC, all of the suppliers, customers and third party providers of GDSC are, or
will be prior to year 2000, Year 2000 Compliant; and (iii) GDSC is taking or has
taken, all commercially reasonable and appropriate action to address and remedy
any deficiencies in the GDSC Computer System which would keep it from becoming
Year 2000 Compliant. As used herein and in SECTION 5.15, "YEAR 2000 COMPLIANT"

fact, or omit to state any material fact necessary to make the statements
therein not misleading. None of the information supplied or to be supplied by

applicable law.

circumstance that is reasonably likely to (a) prevent the transactions
contemplated hereby, including the Merger, from qualifying for

meaning of Section 368(a) of the Code (in which ParentCo, GDSC Merger Sub, DCA

                     REPRESENTATIONS AND WARRANTIES OF DCA
 
    On or prior to the date hereof, DCA has delivered to GDSC schedules ("DCA
DISCLOSURE SCHEDULES") setting forth, among other things, items the disclosure
of which is necessary or appropriate either in response to an express disclosure
requirement contained in a provision hereof or as an exception to one or more
representations or warranties contained in this ARTICLE V; provided, that (i) no
such item is required to be set forth in the DCA Disclosure Schedules as an
exception to a representation or warranty if its absence would not be reasonably
likely to result in the related representation or warranty being deemed untrue
or incorrect under the standard established in the subsequent sentence, and (ii)
the mere inclusion of an item in the DCA Disclosure Schedules as an exception to
a representation or warranty shall not be deemed an admission by a party that
such item represents a material exception or fact, event or circumstance or that
such item is reasonably likely to result in a Material Adverse Effect. No
representation or warranty of DCA contained in this ARTICLE V shall be deemed
untrue or incorrect, and no party hereto shall be deemed to have breached a
representation or warranty, as a consequence of the existence of any fact, event
or circumstance unless such fact, circumstance or event, individually or taken
together with all other facts, events or circumstances inconsistent with any
representation or warranty contained in this ARTICLE V has had or is reasonably
likely to have a Material Adverse Effect on the party making such representation
or
 
                                      A-15
<PAGE>
warranty. The numbers set forth on the DCA Disclosure Schedules correspond to
the particular Section number contained in the Agreement. Information or
disclosure provided with reference to one Section may also be responsive to
information or disclosure responsive to another Section. Therefore, if the
information or disclosure set forth in one Section can be reasonably determined
to apply to information or disclosure in another Section, such information or
disclosure shall constitute disclosure for all applicable Sections. DCA agrees
that with respect to its representations and warranties, DCA shall have the
right to supplement and amend the DCA Disclosure Schedules with respect to any
events occurring after the date of this Agreement and prior to the Effective
Time which such new event or information, when scheduled, shall not constitute a
breach hereof. In the event any such supplement or amendment discloses new
events that are reasonably likely to have a Material Adverse Effect on DCA or on
ParentCo, GDSC shall have the right to terminate the Agreement pursuant to
SECTION 11.1(g).
 
    Subject to the preceding paragraph and except as Previously Disclosed in a
paragraph of the DCA Disclosure Schedules corresponding to the relevant
paragraph below, DCA hereby represents and warrants to GDSC:

    (c) Each of DCA's Subsidiaries has been duly organized and is validly
existing in good standing under the laws of the jurisdiction of its

of which none are issued and outstanding. As of the date hereof, no shares of
DCA Common Stock were held in treasury by DCA or otherwise beneficially owned by
DCA or its Subsidiaries. The outstanding shares of DCA Common Stock or DCA
Preferred Stock have been duly authorized and are validly issued and

<PAGE>
issued or outstanding with respect to its capital stock, and DCA does not have
any commitment to authorize, issue or sell any other shares of its capital stock
or any other Rights.
 
    5.4.  CORPORATE POWER.  DCA and each of its Subsidiaries has the corporate
power and authority to carry on its business as it is now being conducted and to

this Agreement and the transactions contemplated hereby and thereby have been
authorized by all necessary corporate action of DCA and the DCA Board on or
prior to the date hereof. This Agreement is a valid and legally binding
obligation of DCA, enforceable in accordance with its terms (except as
enforceability may be limited by applicable bankruptcy, insolvency,

applicability relating to or affecting creditors' rights or by general equity
principles).

    (a) No consents or approvals of, or filings or registrations with, any

notices with Regulatory Agencies, (ii) the approval of this Agreement by the
stockholders of DCA, and (iii) the filing of an agreement of merger with the

the type described in SECTION 11.1(d).
 
    (b) Subject to receipt of the approvals referred to in the preceding

in all material respects with all the laws, rules and regulations of the
applicable Governmental Authority with which they were filed. The DCA SEC
Reports (i) at the time filed, complied in all material respects with the
applicable requirements of the Securities Act and the Exchange Act, as the case
may be, and (ii) did not at the time they were filed (or if amended or

or (ii) that materially restricts the conduct of business by it or any of its
Subsidiaries that has not been filed with or incorporated by reference in
reports filed under either the Securities Act or the Exchange Act. Neither DCA
nor any of its Subsidiaries is in material default under any material contract,

to Raymond James & Associates, Inc., no action has been taken by DCA that would
give rise to any valid claim against any party hereto for a brokerage

contemplated by this Agreement.
 
    5.13.  EMPLOYEE BENEFIT PLANS.
 
    (a) All benefit and compensation plans, contracts, policies or arrangements
covering current employees or former employees of DCA and its Subsidiaries
(collectively, the "DCA EMPLOYEES") and current or former directors of DCA,
including, but not limited to, "employee benefit plans" within the meaning of
Section 3(3) of ERISA, and deferred compensation, stock option, stock purchase,
stock appreciation rights, stock based, incentive and bonus plans (collectively,
the "DCA BENEFIT PLANS"), are Previously Disclosed. True and complete copies of
all DCA Benefit Plans, including, but not limited to, any trust instruments and
insurance contracts forming a part of any DCA Benefit Plans, and all amendments
thereto have been provided or made available to the other parties hereto.
 
    (b) All employee benefit plans, other than "multiemployer plans" within the
meaning of Section 3(37) of ERISA, covering DCA Employees (the "DCA PLANS"),
have been administered in all material respects in compliance with their terms
and with all applicable laws, [to the extent subject to ERISA], including
without limitation, ERISA and the Code. DCA is not a party to any "employee
pension benefit plan" within the meaning of Section 3(2) of ERISA ("DCA PENSION
PLAN") and which is a defined benefit plan as defined in Section 3(35) of ERISA.
With respect to the employee benefit plan intended to qualify under Section 401
of the Code, a request for a determination letter from the Internal Revenue
Service will be timely applied for to the effect that such plan is, and each
such plan in fact is, or may be timely amended to be, qualified and exempt from
federal income taxes. There is no pending or, to the knowledge of DCA,
threatened litigation relating to any DCA Plan. There are no audits, inquiries,
reviews, proceedings, claims or demands pending with any governmental or
regulatory agency, and there are no facts which could give rise to any material
liability in the event of any such investigation, claim, action, suit, audit,
review or proceeding. Neither DCA nor any of its Subsidiaries has engaged in a
transaction with respect to any DCA Plan that, assuming the taxable period of
such transaction expired as of the date hereof, could subject DCA or any of its
Subsidiaries to a tax or penalty imposed by either Section 4975 of the Code or
Section 502(i) of ERISA.
 
    (c) No liability under Subtitle C or D of Title IV of ERISA has been or is
expected to be incurred by DCA or any of its Subsidiaries with respect to any
ongoing, frozen or terminated "single-employer plan", within the meaning of
Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them,
or the single-employer plan of any entity which is considered one employer with
DCA under Section 4001 of ERISA or Section 414 of the Code (a "DCA ERISA
AFFILIATE"). Neither DCA, any of its Subsidiaries nor an ERISA Affiliate has
contributed to a "multiemployer plan", within the meaning of Section 3(37) of
 
                                      A-19
<PAGE>
ERISA. No notice of a "reportable event", within the meaning of Section 4043 of
ERISA for which the 30-day reporting requirement has not been waived, has been
required to be filed for any DCA Pension Plan or by any DCA ERISA Affiliate
within the 12-month period ending on the date hereof or will be required to be
filed in connection with the transactions contemplated by this Agreement.
 
    (d) All contributions required to be made under the terms of any DCA Plan
have been timely made or have been reflected on the consolidated financial
statements of DCA included in the Regulatory Documents. Neither any DCA Pension
Plan nor any single-employer plan of an ERISA Affiliate has an "accumulated
funding deficiency" (whether or not waived) within the meaning of Section 412 of
the Code or Section 302 of ERISA and no ERISA Affiliate has an outstanding
funding waiver. Neither DCA nor any of its Subsidiaries has provided, or is
required to provide, security to any DCA Pension Plan or to any single-employer
plan of a DCA ERISA Affiliate pursuant to Section 401(a)(29) of the Code.
 
    (e) Under each DCA Pension Plan which is a single-employer plan, as of the
last day of the most recent plan year ended prior to the date hereof, the
actuarially determined present value of all "benefit liabilities", within the
meaning of Section 4001(a)(16) of ERISA (as determined on the basis of the
actuarial assumptions contained in the DCA Plan's most recent actuarial
valuation), did not exceed the then current value of the assets of such DCA
Plan, and there has been no material change in the financial condition of such
DCA Plan since the last day of the most recent plan year.
 
    (f) Neither DCA nor any of its Subsidiaries has any obligations for retiree
health and life benefits under any DCA Benefit Plan. DCA or its Subsidiaries may
amend or terminate any such DCA Benefit Plan at any time without incurring any

Subsidiary has committed an unfair labor practice (within the meaning of the
National Labor Relations Act) or seeking to compel DCA or any such Subsidiary to
bargain with any labor organization as to wages or conditions of employment, nor
is there any strike or other labor dispute involving it or any of its

polychlorinated biphenyls, prior manufacturing operations, dry-cleaning, or
automotive services) involving DCA or any of its Subsidiaries, any currently or
formerly owned or operated property, that could reasonably be expected to result
in any claims, liability or investigations against DCA or any of its
Subsidiaries or result in any restrictions on the ownership, use, or transfer of
any property pursuant to any Environmental Law; and (vi) DCA has delivered to
GDSC copies of all environmental reports, studies, sampling data,
correspondence, filings and other environmental information in its possession or
reasonably available to it relating to DCA and any Subsidiary of DCA, any

with respect to income, franchise or similar Taxes that accrued on or before the

are reflected in the financial statements included in DCA's Regulatory Documents
filed on or prior to the date hereof. Neither DCA nor any of its Subsidiaries is
a party to any Tax allocation or sharing agreement, is or has been a member of

group the common parent of which is or was DCA) or otherwise has any liability
for the Taxes of any person (other than DCA and its Subsidiaries). As of the
date hereof, neither DCA nor any of its Subsidiaries has any reason to believe
that any conditions exist that might prevent or impede the Merger from
qualifying as reorganizations within the meaning of Section 368 of the Code or
Section 351 of the Code.
 
    (b) No Tax is required to be withheld pursuant to Section 1445 of the Code
as a result of the transfer contemplated by this Agreement.
 
    5.18.  BOOKS AND RECORDS.  The books and records of DCA and its Subsidiaries
have been fully, properly and accurately maintained in all material respects,
and there are no material inaccuracies or discrepancies of any kind contained or
reflected therein, and they fairly present the financial position of DCA and its
Subsidiaries.
 
    5.19.  INSURANCE.  DCA has Previously Disclosed all of the insurance
policies, binders, or bonds maintained by DCA or its Subsidiaries ("INSURANCE
POLICIES"). DCA and its Subsidiaries are insured with reputable insurers against
such risks and in such amounts as the management of DCA reasonably has
determined to be prudent for its business, operations, properties and assets.
All the Insurance Policies are
 
                                      A-21
<PAGE>
in full force and effect; DCA and its Subsidiaries are not in material default
thereunder; and all claims thereunder have been filed in due and timely fashion.
 
    5.20.  ACCOUNTING TREATMENT.  As of the date hereof, DCA is not aware of any
reason why the Merger will fail to qualify for "pooling-of-interests" accounting
treatment.
 
    5.21.  ASSETS.  DCA and its Subsidiaries have good and marketable title,

properties used in the businesses of DCA or its Subsidiaries are in good
condition, reasonable wear and tear excepted, and are usable in the ordinary
course of business consistent with DCA's and its Subsidiaries' past practices.
All Assets which are material to DCA's business on a consolidated basis and held
under leases or subleases by DCA or any of its Subsidiaries are held under valid
contracts enforceable in accordance with their respective terms (except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium, or other laws affecting the enforcement of
creditors' rights generally and except that the availability of the equitable
remedy of specific performance or injunctive relief is subject to the discretion
of the court before which any proceedings may be brought), and each such
contract is in full force and effect. The Assets of DCA and its Subsidiaries
include all assets required to operate the business of DCA and its Subsidiaries
as presently conducted.
 
    5.22.  STATEMENTS TRUE AND CORRECT.  None of the information supplied or to
be supplied by DCA or any of its Subsidiaries for inclusion in the Registration
Statement to be filed by ParentCo with the SEC will, when the Registration
Statement becomes effective, be false or misleading with respect to any material
fact, or omit to state any material fact necessary to make the statements
therein not misleading. None of the information supplied or to be supplied by
DCA or any of its Subsidiaries for inclusion in the Proxy Statement to be mailed
to DCA's or GDSC's stockholders in connection with the DCA Meeting or the GDSC
Meeting and any other Governmental Authority in connection with the transactions
contemplated hereby, will, at the respective time such documents are filed, and
with respect to the Proxy Statement, when first mailed to GDSC's or DCA's
stockholders, be false or misleading with respect to any material fact, or omit
to state any material fact necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading, or, in the case of
the Proxy Statement or any amendment thereof or supplement thereto, at the time
of the DCA Meeting or the GDSC Meeting, be false or misleading with respect to
any material fact, or omit to state any material fact necessary to correct any
statement in any earlier communication with respect to the solicitation of any
proxy for the DCA Meeting or the GDSC Meeting. All documents that DCA or any
Subsidiary thereof is responsible for filing with any Regulatory Authority in
connection with the transactions contemplated hereby will comply as to form in
all material respects with the provisions of applicable law.
 
    5.23.  ACCOUNTING, TAX AND REGULATORY.  Neither DCA nor any of its
Subsidiaries has taken any action or has any knowledge of any fact or
circumstance that is reasonably likely to (a) prevent the transactions
contemplated (i) hereby, including the Merger, from qualifying for
pooling-of-interests accounting treatment or as reorganizations within the
meaning of Section 368(a) of the Code (in which ParentCo, GDSC Merger Sub, DCA
Merger Sub, GDSC and DCA is each a party to the reorganization within the
meaning of Section 368(b) of the Code) or (ii) a transfer to a controlled
corporation qualifying under Section 351 of the Code, or (b) materially impede
or delay receipt of any consents of Governmental Authority referred to in
SECTION 5.6(a) of this Agreement or result in the imposition of a condition or
restriction of the type referred to in the last sentence of such Section.
 
    5.24.  NO UNDISCLOSED LIABILITIES.  Except as set forth in the financial
statements filed in connection with the DCA SEC Reports or Previously Disclosed,
DCA does not have any material liability or obligation accrued, contingent or
otherwise.

                                  TERMINATION
 
    11.1.  TERMINATION.  Notwithstanding any other provisions of this Agreement,
this Agreement may be terminated, and the Merger may be abandoned:
 
        (a)  MUTUAL CONSENT.  At any time prior to the Effective Time, by the
    mutual consent of GDSC and DCA, if the Board of Directors of each so
    determines by vote of a majority of the members of its entire Board.
 
        (b)  BREACH.  At any time prior to the Effective Time, by GDSC or DCA,
    if its Board of Directors so determines by vote of a majority of the members
    of its entire Board, in the event of either: (i) a breach by the other party
    of any representation or warranty contained herein (subject to the standard
    set forth herein), which breach cannot be or has not been cured within 30
    days after the giving of written notice to the breaching party of such
    breach; or (ii) a breach by the other party of any of the covenants or
    agreements contained herein, which breach cannot be or has not been cured
    within 30 days after the giving of written notice to the breaching party of
    such breach, provided that such breach (whether under (i) or (ii)) would be
    reasonably likely, individually or in the aggregate with other breaches, to
    result in a Material Adverse Effect.
 
        (c)  DELAY.  At any time prior to the Effective Time, by either GDSC or
    DCA, if its Board of Directors so determines by vote of a majority of the
    members of its entire Board, in the event that the Merger is not consummated
    by March 31, 1999, except to the extent that the failure of the Merger then
    to be consummated arises out of or results from the knowing action or
    inaction of GDSC to the detriment of DCA or DCA to the detriment of GDSC,
    except as permitted hereunder.
 
        (d)  NO APPROVAL.  By GDSC or DCA, if its Board of Directors so
    determines by a vote of a majority of the members of its entire Board, in
    the event (i) the approval of any Governmental Authority required for
    consummation of the Merger and the other transactions contemplated by this
    Agreement shall have been denied by final nonappealable action of such
    Governmental Authority or any Governmental Authority issues a final
    nonappealable order blocking the Merger or (ii) the stockholder approval
    required by SECTION 11.1(a) herein is not obtained at the GDSC Meeting or
    the DCA Meeting, respectively.
 
        (e)  FAILURE TO RECOMMEND, ETC.  At any time prior to the GDSC Meeting
    or the DCA Meeting, by either GDSC or DCA if the Board of Directors of the
    other shall have failed to make its recommendation referred to in SECTION
    8.2, withdrawn such recommendation or modified or changed such
    recommendation in a manner adverse in any respect to the interests of either
    GDSC or DCA for any reason other than as a result of a termination of the
    Agreement allowed pursuant to SECTIONS 11.1(a)-(d) and 11.1(g).
 
        (f)  ACQUISITION PROPOSAL.  This Agreement may be terminated by either
    GDSC or DCA by written notice to the other if either GDSC or DCA (i)
    receives an Acquisition Proposal, (ii) receives the advice of its outside
    counsel that to proceed with the Merger will violate the fiduciary duties of
    its Board of Directors to its stockholders in light of such Acquisition
    Proposal, and (iii) after receiving such advice, determines to accept such
    proposal; provided, however, that neither party shall be entitled to
    terminate this Agreement pursuant to this SECTION 11.1(f) unless it shall
    have provided the other with written notice of such a possible determination
    (which written notice will inform the other of the material terms and
    conditions of the proposal, including the identity of the proponent) not
    less than two business days prior to such determination.
 
        (g)  DISCLOSURE SCHEDULE AMENDMENT OR SUPPLEMENT.  At any time prior to
    the Effective Time by either GDSC or DCA if its board of Directors so
    determines by vote of a majority of the members of its entire Board, in the
    event the other party amends their Disclosure Schedule pursuant to the
 
                                      A-36
<PAGE>
    introductory paragraphs of Articles IV and V, respectively and discloses
    events that would be reasonably likely to result in a Material Adverse
    Effect on the other party or ParentCo.
 
    11.2.  EFFECT OF TERMINATION AND ABANDONMENT.  In the event of termination
of this Agreement and the abandonment of the Merger pursuant to this ARTICLE XI,
no party to this Agreement shall have any liability or further obligation to any
other party hereunder except (i) as set forth in SECTIONS 11.3and 12.1, and (ii)
that termination under SECTION 11.1(b) will not relieve a breaching party from
liability for any breach of this Agreement giving rise to such termination;
provided, however, in no event shall the breaching party pay to the
non-breaching party for such a breach an amount greater than the actual out-of-
pocket costs and expenses of the non-breaching party in connection with this
Agreement.
 
    11.3.  TERMINATION FEE.  The parties agree and acknowledge that it is
impractical to ascertain the precise amount of damage to either GDSC or DCA as a
result of a failure to consummate the Merger and the other transactions
contemplated hereby due to a termination of this Agreement by either party
pursuant to SECTION 11.1(e) or SECTION 11.1(f) hereof. Accordingly, in the event
of such termination pursuant to SECTION 11.1(e) or SECTION 11.1(f) by either
GDSC or DCA, such non-terminating party (pursuant to SECTION 11.1(e) hereof) or
such terminating party (pursuant to SECTION 11.1(f) hereof) shall pay to such
other party the sum of One Million Five Hundred Thousand Dollars ($1,500,000)
("TERMINATION FEE") which amount shall be payable in same date funds no later
than five business days after the date of either GDSC's or DCA's request. The
Termination Fee shall be the sole and exclusive remedy of GDSC or DCA, as the
case may be, for events of termination pursuant to SECTIONS 11.1(e) and (f).
Notwithstanding the foregoing, nothing contained in this SECTION 11.3 shall
affect either GDSC's or DCA's ability to recover for damages which result from a
termination of this Agreement pursuant to SECTION 11.1(b) and SECTION 11.2.
 
                                  ARTICLE XII
                                 MISCELLANEOUS
 
    12.1.  SURVIVAL.  No representations, warranties, agreements and covenants
contained in this Agreement shall survive the Effective Time (other than
SECTIONS 1.2, 1.6, 8.10, 8.15, 8.16 and this ARTICLE XII which shall survive the
Effective Time) or the termination of this Agreement if this Agreement is
terminated prior to the Effective Time (other than SECTIONS 11.2, 11.3 and this
ARTICLE XII which shall survive such termination).
 
    12.2.  WAIVER; AMENDMENT.  Prior to the Effective Time, any provision of
this Agreement may be (i) waived by the party benefited by the provision, or
(ii) amended or modified at any time, by an agreement in writing between the
parties hereto executed in the same manner as this Agreement, except that after
the GDSC Meeting and the DCA Meeting, this Agreement may not be amended if it
would violate either the WBCA or DGCL or reduce the consideration to be received
by GDSC or DCA stockholders in the Merger.
 
    12.3.  COUNTERPARTS.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed to constitute an original.
 
    12.4.  GOVERNING LAW; WAIVER OF JURY TRIAL.  This Agreement shall be
governed by, and interpreted in accordance with, the laws of the State of
Delaware applicable to contracts made and to be performed entirely within such
State (except to the extent that mandatory provisions of Federal law are
applicable). Each of the parties hereto hereby irrevocably waives any and all
right to trial by jury in any legal proceeding arising out of or related to this
Agreement or the transactions contemplated hereby.
 
    12.5.  EXPENSES.  Each party hereto will bear all expenses incurred by it in
connection with this Agreement and the transactions contemplated hereby.

October 15, 1998
 
Board of Directors
Gentle Dental Service Corporation
222 North Sepulveda Boulevard, Suite 740
El Segundo, California 90245-4340
 
Members of the Board:
 
    You have requested our opinion as to the fairness, from a financial point of
view, of the Exchange Ratio (as defined below) to Gentle Dental Service
Corporation (the "Company"). The Company has entered into an Agreement and Plan
of Reorganization and Merger, dated as of October 15, 1998 (the "Merger
Agreement"), with Wisdom Holdings, Inc. ("Parent"), Wisdom Acquisition Corp. I
("GDSC Merger Sub"), Wisdom Acquisition Corp. II ("DCA Merger Sub") and Dental
Care Alliance, Inc. ("DCA"), pursuant to which, among other things, GDSC Merger
Sub will be merged with and into the Company (the "Company Merger"), with the
Company continuing as the surviving corporation, and DCA Merger Sub will be
merged with and into DCA (the "DCA Merger" and, together with the Company
Merger, the "Merger"), with DCA continuing as the surviving corporation. The
Merger Agreement provides, among other things, that (i) in the Company Merger,
each outstanding share of common stock, no par value, of the Company (the
"Company Common Stock") will be converted into and exchanged for the right to
receive one share of common stock, no par value, of Parent (the "Parent Common
Stock"), and (ii) each outstanding share of common stock, par value $.01 per
share, of DCA (the "DCA Common Stock") will be converted into and exchanged for
the right to receive 1.670 shares of Parent Common Stock (the "Exchange Ratio").
 
    In arriving at our opinion, we reviewed the Merger Agreement and held
discussions with certain senior officers and other representatives and advisors
of the Company and certain senior officers and other representatives and
advisors of DCA concerning the business, operations and prospects of the Company
and DCA. We examined certain publicly available business and financial
information relating to the Company and DCA as well as certain financial
forecasts and other data for the Company and DCA, which were provided to us by
the respective managements of the Company and DCA, including information
relating to certain strategic implications and operational benefits anticipated
from the Merger. We reviewed the financial terms of the Merger as set forth in
the Merger Agreement in relation to, among other things: current and historical
market prices and trading volumes of the Company Common Stock and DCA Common
Stock; the respective companies' historical and projected earnings; and the
capitalization and financial condition of the Company and DCA. We considered, to
the extent publicly available, the financial terms of certain other similar
recently effected transactions that we considered comparable to the Merger and
analyzed certain financial, stock market and other publicly available
information relating to the businesses of other companies whose operations we
considered relevant in evaluating those of the Company and DCA. We also
evaluated the potential pro forma financial impact of the Merger on the Company.
In addition to the foregoing, we conducted such other analyses and examinations
and considered such other financial, economic and market criteria as we deemed
appropriate in arriving at our opinion.
 
    In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information publicly available or furnished to or otherwise reviewed by or
discussed with us. With respect to financial forecasts and other information
provided to or otherwise reviewed by or discussed with us, we have been advised
by the managements of the Company and DCA that such forecasts and other
information were reasonably prepared on bases reflecting the best currently
available estimates and judgments of the respective managements of the

Company and DCA as to the expected future financial performance of the Company
and DCA and the strategic implications and operational benefits anticipated from
the Merger.
 
    We have assumed, with your consent, that the Merger will be treated as a
pooling-of-interests in accordance with generally accepted accounting principles
and as a tax-free reorganization for federal income tax purposes.
 
    Our opinion, as set forth herein, relates to the relative values of the
Company and DCA. We are not expressing any opinion as to what the value of the
Parent Common Stock actually will be when issued to stockholders pursuant to the
Merger or the price at which the Parent Common Stock will trade subsequent to
the Merger. We have not made or been provided with an independent evaluation or
appraisal of the assets or liabilities (contingent or otherwise) of the Company
and DCA nor have we made any physical inspection of the properties or assets of
the Company or DCA. We have not been asked to consider, and our opinion does not
address, the relative merits of the Merger as compared to any alternative
business strategies that might exist for the Company or the effect of any other
transaction in which the Company might engage. Our opinion is necessarily based
upon information available to us, and financial, stock market and other
conditions and circumstances existing and disclosed to us, as of the date
hereof.
 
    Salomon Smith Barney Inc. has been engaged to render financial advisory
services to the Company in connection with the Merger and will receive a fee for
our services, a significant portion of which is contingent upon the consummation
of the Merger. We also will receive a fee upon the delivery of this opinion. In
the ordinary course of our business, we and our affiliates may hold or actively
trade the equity and debt securities of the Company and DCA for our own account
or for the account of our customers and, accordingly, may at any time hold a
long or short position in such securities. In addition, we and our affiliates
(including Citigroup Inc. and its affiliates) may maintain business
relationships with the Company and DCA.
 
    Our advisory services and the opinion expressed herein are provided for the
use of the Board of Directors of the Company in its evaluation of the proposed
Merger, and our opinion is not intended to be and does not constitute a
recommendation to any stockholder as to how such stockholder should vote on the
proposed Merger. Our opinion may not be published or otherwise used or referred
to, nor shall any public reference to Salomon Smith Barney Inc. be made, without
our prior written consent.
 
    Based upon and subject to the foregoing, our experience as investment
bankers, our work as described above and other factors we deemed relevant, we
are of the opinion that, as of the date hereof, the Exchange Ratio is fair, from
a financial point of view, to the Company.
 
                                          Very truly yours,
 
                                          SALOMON SMITH BARNEY INC.

October 15, 1998
 
Board of Directors
Dental Care Alliance, Inc.
1343 Main Street
7th Floor
Sarasota, FL 34236
 
Members of the Board:
 
    We understand that Dental Care Alliance, Inc. ("DCA" or the "Company") is
contemplating a transaction whereby DCA and Gentle Dental Service Corporation
("Gentle") will be merged with and into a new, as yet unnamed holding company
("ParentCo") pursuant to the terms of an Agreement and Plan of Reorganization
and Merger and the exhibits and schedules thereto dated as of October 15, 1998
(the "Merger Agreement"), such that DCA becomes a wholly owned subsidiary of
ParentCo (the "Transaction"). Pursuant to the Transaction, each outstanding
share of DCA, $.01 par value (the "DCA Common Stock"), shall be converted into
shares of ParentCo common stock (the "ParentCo Common Stock"), based on an
exchange ratio (the "Exchange Ratio") as set forth in the Merger Agreement. The
terms and conditions of the Transaction are more fully set forth in the Merger
Agreement.
 
    You have requested our opinion as to whether the Exchange Ratio is fair to
the holders of DCA Common Stock (the "Holders"), from a financial point of view.
 
    In connection with our review of the proposed Transaction and the
preparation of our opinion herein, we have, among other things:
 
    1.  reviewed the annual report to stockholders on Form 10-K filed April 1,
       1998, the quarterly reports to stockholders on Forms 10-Q filed May 14,
       1998 and August 14, 1998, and other publicly available financial
       information of DCA;
 
    2.  reviewed the annual report to stockholders on Form 10-K filed May 29,
       1998 and amended August 3, 1998, the quarterly reports to stockholders on
       Forms 10-Q filed May 15, 1998 and August 14, 1998, and other publicly
       available financial information of Gentle;
 
    3.  reviewed certain non-public information prepared by the management of
       DCA, including financial statements, financial projections, and other
       financial and operating data concerning DCA;
 
    4.  reviewed certain non-public information prepared by the management of
       Gentle, including financial statements, financial projections, and other
       financial and operating data concerning Gentle;
 
    5.  discussed the past and current operations and financial condition and
       the prospects of DCA and Gentle with senior executives of DCA and Gentle,
       respectively;
 
    6.  reviewed publicly available financial and stock market data with respect
       to certain other companies in lines of business we believe to be
       generally comparable to those of DCA and Gentle;
 
    7.  considered the pro forma effects of the Transaction on DCA's financial
       statements and reviewed certain estimates of synergies prepared by the
       managements of DCA and Gentle;
 
    8.  reviewed the historical market prices of the DCA Common Stock and the
       common stock of Gentle;
 
    9.  compared the financial terms of the Transaction with the financial terms
       of certain other transactions which we believe to be generally comparable
       to the Transaction;
 
                                      C-1
<PAGE>
    10. reviewed a draft of the Merger Agreement;
 
    11. conducted other financial analyses, studies, and investigations, and
       considered other information as we deemed necessary or appropriate.
 
    In connection with our review, we have not assumed any responsibility for
independent verification for any of the information reviewed by us for the
purpose of this opinion and have relied on its being complete and accurate in
all material respects. In addition, we have not made or received any independent
evaluation or appraisal of any of the assets or liabilities (contingent or
otherwise) of DCA and Gentle, nor have we been furnished with any such
evaluation or appraisal. With respect to the financial forecasts, estimates,
projections, pro forma effects, calculations of synergies and other information
referred to above, we have assumed, at your direction, that they have been
reasonably prepared on a basis reflecting the best currently available estimates
and judgments of the management of each company, and we have relied upon each
party to advise us promptly if any such information previously provided to or
discussed with us became inaccurate or was required to be updated during the
period of our review. In addition, we have assumed the Transaction will be
consummated substantially in accordance with the terms set forth in the draft of
the Merger Agreement.
 
    In rendering our opinion, we have assumed, with your consent, that the
Transaction will receive pooling-of-interests accounting treatment and will
qualify as a tax-free reorganization. Our opinion is necessarily based on the
economic, market financial and other circumstances and conditions in effect on
October 15, 1998, and any material change in such circumstances or conditions
would require reevaluation of this opinion, which we are under no obligation to
undertake.
 
    We express no opinion as to the underlying business decision to effect the
Transaction, the structure or tax consequences of the Merger Agreement, or the
availability or advisability of any alternatives to the Transaction. This letter
does not express any opinion as to the likely trading range for the ParentCo
Common Stock following the consummation of the Transaction, which may vary
depending on numerous factors that generally impact the price of securities. Our
opinion is limited to the fairness, from a financial point of view, of the
Exchange Ratio to the Holders. We express no opinion with respect to any other
reasons, legal, business, or otherwise, that may support the decision of the
Board of Directors to approve, or in DCA's decision to consummate, the
Transaction.
 
    In conducting our investigation and analyses and in arriving at our opinion
expressed herein, we have taken into account such accepted financial and
investment banking procedures and considerations as we have deemed relevant,
including the review of (i) historical and projected revenues, operating
earnings, net income and capitalization of DCA and Gentle and certain other
publicly held companies in businesses we believe to be comparable to DCA and
Gentle; (ii) the current and projected financial position and results of
operations of DCA and Gentle; (iii) the historical market prices and trading
activity of the DCA Common Stock and the common stock of Gentle; (iv) financial
and operating information concerning selected business combinations which we
deemed comparable in whole or in part; and (v) the general condition of the
securities markets.
 
    Raymond James & Associates ("Raymond James") is actively involved in the
investment banking business and regularly undertakes the valuation of investment
securities in connection with public offerings, private placements, business
combinations and similar transactions. In the past, Raymond James has performed
certain investment banking services for DCA and has received customary fees for
such services. Raymond James has acted as financial advisor to the Board of
Directors of DCA in connection with the Transaction and will receive a fee upon
the consummation thereof, which fee is contingent upon the value of the
Transaction. In the ordinary course of business, Raymond James may trade in the
securities of DCA and Gentle for its own account and for the accounts of our
customers and, accordingly, may at any time hold a long or short position in
such securities.
 
                                      C-2
<PAGE>
    It is understood that our advisory services and opinion expressed herein
were prepared for the use of the Board of Directors of DCA only in evaluating
the proposed Transaction and do not constitute a recommendation to any
shareholder of DCA regarding how such shareholder should vote on the proposed
Transaction, nor is this letter intended to confer rights or remedies upon
ParentCo or Gentle or the shareholders of DCA, Gentle, or ParentCo. Furthermore,
this letter should not be construed as creating any fiduciary duty on the part
of Raymond James to any such party. This opinion is not to be quoted or referred
to, in whole or in part, without the prior written consent of Raymond James,
which will not be unreasonably withheld. We have consented to the inclusion of
this letter in its entirety in the proxy statement to be filed by DCA with the
Securities and Exchange Commission in connection with the Transaction.
 
    In arriving at this opinion, Raymond James did not attribute any particular
weight to any analysis or factor considered by it, but rather made qualitative
judgments as to the significance and relevance of each analysis and factor.
Accordingly, Raymond James believes that its analyses must be considered as a
whole and that selecting portions of its analyses, without considering all
analyses, would create an incomplete view of the process underlying this
opinion.
 
    Based upon and subject to the foregoing, it is our opinion that, as of
October 15, 1998, the Exchange Ratio pursuant to the Merger Agreement is fair,
from a financial point of view, to the Holders.
 
                                          Respectfully submitted,
 
                                          RAYMOND JAMES & ASSOCIATES, INC.

        (a)  CAPACITY.  Stockholder has all requisite capacity and authority to
    enter into and perform his, her or its obligations under this Agreement.
 
        (b)  BINDING AGREEMENT.  This Agreement constitutes the valid and
    legally binding obligation of Stockholder, subject to bankruptcy,
    insolvency, fraudulent transfer, reorganization, moratorium and similar laws
    of general applicability relating to or affecting creditors' rights and to
    general equity principles.
 
        (c)  NON-CONTRAVENTION.  The execution and delivery of this Agreement by
    Stockholder does not, and the performance by Stockholder of his, her or its
    obligations hereunder and the consummation by Stockholder of the
    transactions contemplated hereby will not, violate or conflict with, or
    constitute a default under, any agreement, instrument, contract or other
    obligation or any order, arbitration award, judgment or decree to which
    Stockholder is a party or by which Stockholder is bound, or any statute,
    rule or regulation to which Stockholder is subject or, in the event that
    Stockholder is a corporation, partnership, trust or other entity, any
    charter, bylaw or other organizational document of the Stockholder.
 
        (d)  OWNERSHIP OF SHARES.  Stockholder has good title to all of the
    Shares as of the date hereof, and, except as set forth on ANNEX I hereto,
    the Shares are so owned free and clear of any liens, security interests,
    charges or other encumbrances.
 
    5.  SPECIFIC PERFORMANCE AND REMEDIES.  Stockholder acknowledges that it
will be impossible to measure in money the damage to ParentCo, GDSC, GDSC
Acquisition Corp., and DCA (each are an "OTHER PARTY" and collectively the
"OTHER PARTIES") if Stockholder fails to comply with the obligations imposed by
this Agreement and that, in the event of any such failure, the Other Parties
will not have an adequate remedy at law or in damages. Accordingly, Stockholder
agrees that injunctive relief or other equitable remedy, in addition to remedies
at law or in damages, is the appropriate remedy for any such failure and will
not oppose the granting of such relief on the basis that any Other Party has an
adequate remedy at law. Stockholder agrees that he/she/it will not seek, and
agrees to waive any requirement for, the securing or posting of a bond in
connection with any of the Other Parties seeking or obtaining such equitable
relief. In addition, after discussing the matter with Stockholder any Other
Party shall have the right to inform any third party that such Other Party
reasonably believes to be, or to be contemplating, participating with
Stockholder or receiving from Stockholder assistance in violation of this
Agreement, of the terms of this Agreement and of the rights of the Other Parties
hereunder, and that participation by any such persons with Stockholder in
activities in violation of Stockholder's agreement with the Other Parties set
forth in this Agreement may give rise to claims by the Other Parties against
such third party.
 
    6.  TERM OF AGREEMENT; TERMINATION.
 
        (a) The term of this Agreement shall commence on the date hereof.
 
        (b) This Agreement shall terminate upon the date, if any, of the
    termination of the Merger Agreement prior to the Effective Time in
    accordance with its terms. Upon such termination, no party shall have any
    further obligations or liabilities hereunder; PROVIDED, HOWEVER, such
    termination shall not relieve any party from liability for any breach of
    this Agreement PRIOR to such termination.
 
        (c) If the Merger Agreement is not terminated prior to the Effective
    Time, this Agreement (except for the provisions of Sections 4, 5, 8, 10, and
    11, which shall survive the Effective Time) shall terminate upon the
    Effective Time. Upon termination of this Agreement, no party shall have any
 
                                      D-2
<PAGE>
    further obligations or liabilities under this Agreement: PROVIDED, HOWEVER,
    such termination shall not relieve any party from liability for any breach
    of any Section hereof prior to such termination.
 
    7.  ENTIRE AGREEMENT.  This Agreement supersedes all prior agreements,
written or oral, among the parties hereto with respect to the subject matter
hereof and contains the entire agreement among the parties with respect to the
subject matter hereof. This Agreement may not be amended, supplemented or
modified, and no provisions hereof may be modified or waived, except by an
instrument in writing signed by each party hereto. No waiver of any provisions
hereof by either party shall be deemed a waiver of any other provisions hereof
by any such party, nor shall any such waiver be deemed a continuing waiver of
any provision hereof by such party.
 
    8.  NOTICES.  All notices, requests, claims, demands or other communications
hereunder shall be in writing and shall be deemed given when delivered

on its principal bank loans or, if none, at a rate that is fair and equitable
under all the circumstances.

corporate actions:
 
    (a) Consummation of a plan of merger to which the corporation is a party (i)
if shareholder approval is required for the merger by RCW 23B.11.030,
23B.11.080, or the articles of incorporation and the shareholder is entitled to
vote on the merger, or (ii) if the corporation is a subsidiary that is merged
with its parent under RCW 23B.11.040;

property of the corporation other than in the usual and regular course of
business, if the shareholder is entitled to vote on the sale or exchange,

order or a sale for cash pursuant to a plan by which all or substantially all of
the net proceeds of the sale will be distributed to the shareholders within one

    (e) Any corporate action taken pursuant to a shareholder vote to the extent
the articles of incorporation, bylaws, or a resolution of the board of directors
provides that voting or nonvoting shareholders are entitled to dissent and
obtain payment for their shares.
 
(2) A shareholder entitled to dissent and obtain payment for the shareholder's
shares under this chapter may not challenge the corporate action creating the
shareholder's entitlement unless the action fails to comply with the procedural
requirements imposed by this title, RCW 25.10.900 through 25.10.955, the of
incorporation, or the bylaws, or is fraudulent with respect to the shareholder
or the corporation.

the shareholder's shares shall terminate upon the occurrence of any one of the
following events:

corporate action; or

the shareholder asserts dissenters' rights. The rights of a partial dissenter
under this subsection are determined as if the shares as to which the dissenter
dissents and the dissenter's other shares were registered in the names of
different shareholders.

shareholder's written consent to the dissent not later than the time the

    (b) An explanation of how the corporation estimated the fair value of the
shares;

23B.13.260. FAILURE TO TAKE ACTION
 
(1) If the corporation does not effect the proposed action within sixty days
after the date set for demanding payment and depositing share certificates, the
corporation shall return the deposited certificates and release any transfer
restrictions imposed on uncertificated shares.
 
(2) If after returning deposited certificates and releasing transfer
restrictions, the corporation wishes to undertake the proposed action, it must
send a new dissenters' notice under RCW 23B.13.220 and repeat the payment demand
procedure.
 
23B.13.270. AFTER-ACQUIRED SHARES
 
(1) A corporation may elect to withhold payment required by RCW 23B.13.250 from
a dissenter unless the dissenter was the beneficial owner of the shares before
the date set forth in the dissenters' notice as the date of the first
announcement to news media or to shareholders of the terms of the proposed
corporate action.
 
(2) To the extent the corporation elects to withhold payment under subsection
(1) of this section, after taking the proposed corporate action, it shall
estimate the fair value of the shares, plus accrued interest, and shall pay this
amount to each dissenter who agrees to accept it in full satisfaction of the
dissenter's demand. The corporation shall send with its offer an explanation of
how it estimated the fair value of the shares, an explanation of how the

                                      E-4
<PAGE>
(1) A dissenter may notify the corporation in writing of the dissenter's own
estimate of the fair value of the dissenter's shares and amount of interest due,
and demand payment of the dissenter's estimate, less any payment under RCW
23B.13.250, or reject the corporation's offer under RCW 23B.13.270 and demand
payment of the dissenter's estimate of the fair value of the dissenter's shares
and interest due, if:
 
    (a) The dissenter believes that the amount paid under RCW 23B.13.250 or
offered under RCW 23B.13.270 is less than the fair value of the dissenter's
shares or that the interest due is incorrectly calculated;
 
    (b) The corporation fails to make payment under RCW 23B.13.250 within sixty
days after the date set for demanding payment; or
 
    (c) The corporation does not effect the proposed action and does not return
the deposited certificates or release the transfer restrictions imposed on
uncertificated shares within sixty days after the date set for demanding
payment.
 
(2) A dissenter waives the right to demand payment under this section unless the
dissenter notifies the corporation of the dissenter's demand in writing under
subsection (1) of this section within thirty days after the corporation made or
offered payment for the dissenter's shares.
 
23B.13.300. COURT ACTION
 
(1) If a demand for payment under RCW 23B.13.280 remains unsettled, the
corporation shall commence a proceeding within sixty days after receiving the
payment demand and petition the court to determine the fair value of the shares
and accrued interest. If the corporation does not commence the proceeding within
the sixty-day period, it shall pay each dissenter whose demand remains unsettled
the amount demanded.
 
(2) The corporation shall commence the proceeding in the superior court of the
county where a corporation's principal office, or, if none in this state, its
registered office, is located. If the corporation is a foreign corporation
without a registered office in this state, it shall commence the proceeding in
the county in this state where the registered office of the domestic corporation
merged with or whose shares were acquired by the foreign corporation was
located.
 
(3) The corporation shall make all dissenters, whether or not residents of this
state, whose demands remain unsettled, parties to the proceeding as in an action
against their shares and all parties must be served with a copy of the petition.
Nonresidents may be served by registered or certified mail or by publication as
provided by law.
 
(4) The corporation may join as a party to the proceeding any shareholder who
claims to be a dissenter but who has not, in the opinion of the corporation,
complied with the provisions of this chapter. If the court determines that such
shareholder has not complied with the provisions of this chapter, the
shareholder shall be dismissed as a party.
 
(5) The jurisdiction of the court in which the proceeding is commenced under
subsection (2) of this section is plenary and exclusive. The court may appoint
one or more persons as appraisers to receive evidence and recommend decision on
the question of fair value. The appraisers have the powers described in the
order appointing them, or in any amendment to it. The dissenters are entitled to
the same discovery rights as parties in other civil proceedings.
 
(6) Each dissenter made a party to the proceeding is entitled to judgment (a)
for the amount, if any, by which the court finds the fair value of the
dissenter's shares, plus interest, exceeds the amount paid by the
 
                                      E-5
<PAGE>
corporation, or (b) for the fair value, plus accrued interest, of the
dissenter's after-acquired shares for which the corporation elected to withhold
payment under RCW 23B.13.270.
 
23B.13.310. COURT COSTS AND COUNSEL FEES
 
(1) The court in a proceeding commenced under RCW 23B.13.300 shall determine all
costs of the proceeding, including the reasonable compensation and expenses of
appraisers appointed by the court. The court shall assess the costs against the
corporation, except that the court may assess the costs against all or some of
the dissenters, in amounts the court finds equitable, to the extent the court
finds the dissenters acted arbitrarily, vexatiously, or not in good faith in
demanding payment under RCW 23B.13.280.
 
(2) The court may also assess the fees and expenses of counsel and experts for
the respective parties, in amounts the court finds equitable:
 
    (a) Against the corporation and in favor of any or all dissenters if the
court finds the corporation did not substantially comply with the requirements
of RCW 23B.13.200 through 23B.13.280; or
 
    (b) Against either the corporation or a dissenter, in favor of any other
party, if the court finds that the party against whom the fees and expenses are
assessed acted arbitrarily, vexatiously, or not in good faith with respect to
the rights provided by chapter 23B.13 RCW.
 
    (3) If the court finds that the services of counsel for any dissenter were
of substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the corporation, the court may
award to these counsel reasonable fees to be paid out of the amounts awarded the
dissenters who were benefited.

ITEM 20. INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
    Wisdom Holdings is a Delaware corporation. Section 145 of the General
Corporation Law of the State of Delaware contains detailed provisions on
indemnification of directors and officers of a Delaware corporation against
expenses, judgments, fines and amounts paid in settlement, actually and
reasonably incurred in connection with litigation.
 
    By amendment to its Certificate of Incorporation, Wisdom Holdings has
provided for indemnification of directors and officers. The provision provides
that any person shall, to the fullest extent permitted by the General
Corporation Law of the State of Delaware, be indemnified and reimbursed by
Wisdom Holdings for expenses and liabilities imposed upon the person in
connection with any action, suit or proceeding, civil or criminal, or threat
thereof, in which the person may be involved by reason of the person being or
having been a director, officer, employee or agent of Wisdom Holdings, or of any
corporation or organization which the person served in any capacity at the
request of Wisdom Holdings. Wisdom Holdings' Certificate of Incorporation also
provides that a director of Wisdom Holdings shall not be personally liable to
Wisdom Holdings or its stockholders for monetary damages for breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to Wisdom Holdings or its stockholders, (ii) for acts or
omissions not in good faith or which involve 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
any improper personal benefit. Wisdom Holdings' Certificate of Incorporation
also calls for the liability of its directors to be further limited to the full
extent permitted by Delaware law as it is amended.

ITEM 22. UNDERTAKINGS.
 
    (a) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable, each filing of an employee benefit
plan's annual report pursuant to Section Exchange Act of 1934) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
    (b) The undersigned registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
propsectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
    (c) The registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (c) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial BONA FIDE offering thereof.
 
    (d) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the provisions described under Item 20 above, or
otherwise, the registrant 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
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant 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 registrant 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 Act and will
be governed by the final adjudication of such issue.
 
    (e) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.
 
    (f) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

PERSONAL AND CONFIDENTIAL

Dr. Dany Y. Tse
Co-Chairman, Founder and President
  of Clinical Services Council
Gentle Dental Service Corporation
900 Washington St., Suite 1100
Vancouver, WA 98660

       RE:  SEPARATION AGREEMENT AND MUTUAL RELEASE

Dear Dany:

     This letter, when signed by you, will constitute our Agreement regarding 
your separation from Gentle Dental Service Corporation ("Gentle Dental").  
The parties to this Agreement are you and Gentle Dental.

     1.   TERMINATION OF EMPLOYMENT.  Your employment with Gentle Dental will 
continue through December 31, 1998 (the "Termination Date"), when your 
employment with Gentle Dental will end.  By execution of this Agreement, you 
will resign as an employee, officer and director of Gentle Dental effective 
as of December 31, 1998.  In addition, your Employment Agreement with Gentle 
Dental dated July 1, 1998 (the "Employment Agreement") is hereby terminated 
effective as of December 31, 1998.  Any and all post-termination obligations 
of either party under the Employment Agreement are superseded and replaced by 
this Agreement.  The Proprietary Information Agreement between you and Gentle 
Dental is not terminated.

     2.   CONSULTING AGREEMENT.  During the period from January 1, 1999 to 
December 31, 2000 (the "Consulting Period"), you agree to provide consulting 
services to the Company on a project basis related to your area of expertise 
(i.e. Clinical Services in Dentistry) at mutually agreeable times and 
completion dates.  You understand that the Company will not provide office 
space as part of the consulting arrangement.  You will be paid the following 
annual amounts during the Consulting Period:

           1999:     $257,580 ($243,000 increased by 6%)
           2000:     $273,035 ($257,580 increased by 6%)

The consulting payments shall be made in monthly installments equal to 1/12th 
of the annual amount.  The first monthly consulting payment is due on January 
31, 1999 and subsequent payments are due on the last day of each month during 
the Consulting Period.  All payments will be subject to applicable income tax 
and employment tax withholding.

<PAGE>

     3.   SEVERANCE PAYMENTS.  Gentle Dental will pay you severance payments 
from January 1, 2001 through June 30, 2003 (the "Severance Period").  You 
will be paid the following annual amounts during the Severance Period:

           2001:     $289,417 ($273,035 increased by 6%)
           2002:     $306,782 ($289,417 increased by 6%)
           2003:     $162,594 (1/2 of $306,782 increased by 6%)

The severance payments shall be made in monthly installments equal to 1/12th 
of the annual amount (1/6th of the annual amount in 2003).  The first monthly 
severance payment is due on January 31, 2001 and subsequent payments are due 
on the last day of each month during the Severance Period.  All payments will 
be subject to applicable income tax and employment tax withholding.

     4.   STOCK OPTIONS.  Effective on December 31, 1998, all options you 
hold to purchase Gentle Dental stock will be fully vested and exercisable 
consistent with the terms of the Employment Agreement.  Under the terms of 
the two stock options granted to you in 1998, you will be entitled to 
exercise those options at any time until the expiration of three months after 
the end of the Consulting Period.  Under the terms of the three stock options 
granted to you prior to 1998, you will be entitled to exercise those options 
only until March 31, 1999.

    5.   COMPANY BENEFITS.  Gentle Dental will request its health care 
insurer that you and any dependents currently insured under its health 
benefits plan (the "Plan") be continued as participants during the Consulting 
and Severance Periods.  If that request is allowed, Gentle Dental will pay 
for the benefits or premiums on the same basis that it pays for its 
employees.  If you are entitled to participate in the Plan during the 
Consulting and Severance Periods, to the extent permitted by the Plan, you 
will be entitled to continue your group health coverage through Gentle Dental 
under a federal law called COBRA after the end of the Severance Period.  
Under COBRA, you may elect to purchase continued group health coverage 
through Gentle Dental at the full premium rate plus an administrative fee for 
up to an 18-month period.

     If Gentle Dental's request to allow you and your dependents to remain on 
the Plan is denied, or if the eligibility of you and your dependents to be 
participants in the Plan ends before the end of the Consulting and Severance 
Periods, and you elect COBRA benefits, Gentle Dental shall reimburse you for 
the continuation of benefits for you and your dependents under COBRA until 
the end of the Severance Period in the amount Gentle Dental would have paid 
if you continued to be eligible under the Plan.  If your elibility for COBRA 
benefits ends before the end of the Consulting and Severance Periods, you 
will arrange for your own health insurance coverage and Gentle Dental will 
reimburse you on a monthly basis until the end of the Severance Period an 
amount equal to the amount Gentle Dental would have paid to cover you under 
the Plan if you were eligible.

     Gentle Dental will also request its group life insurer that you be 
continued as a participant in that plan during the Consulting and Severance 
Periods.  If that request is allowed, Gentle Dental will pay the premiums on 
the same basis that it pays for its employees.

     6.   PROFESSIONAL CORPORATIONS.  By execution of this Agreement, you 
will resign effective as of December 31, 1998 any position you hold as an 
officer or director of Dany Tse,

                                           2
<PAGE>

P.C., Tse, Saiget, Watanabe & McClure, Inc., P.S., and Gentle Dental of 
Oregon, P.C. (the "Professional Corporations").  You acknowledge that under 
the terms of the Shares Acquisition Agreements between Gentle Dental, you, 
and each of the Professional Corporations, Gentle Dental intends to exercise 
its right to cause you to transfer your stock in each of the Professional 
Corporations to one or more eligible dentists.  You agree to cooperate fully 
and to sign any documents necessary or appropriate to effectuate those 
transfers.  You also agree to execute a Mutual Release with each of the 
Professional Corporations.

     7.   RESTRICTIVE COVENANTS.

     (a)   NON-SOLICITATION. You agree that during the period from January 1, 
1999 to December 31, 2000, you shall not, directly or indirectly, solicit, 
entice, encourage or induce any person (other than your wife) who at any time 
within one month prior to your termination of employment or at any time 
during the Consulting Period shall have been an employee of Gentle Dental or 
any of its subsidiaries, or who is a dentist who is employed by or performing 
professional services for any dental practice managed by Gentle Dental or one 
of its subsidiaries, to become employed by or associated with any person, 
firm or corporation other than Gentle Dental, and you shall not approach any 
such employee or dentist for such purpose or encourage the taking of such 
actions by any other person, firm or corporation or assist any such person, 
firm or corporation in taking such action; provided, however, that this 
subsection shall not prohibit you from taking any such action with respect to 
any employee or other person whose employment or service relationship was 
terminated by Gentle Dental prior to any such action by you.

     (b)   NON-COMPETE.  You agree that during the period from January 1, 
1999 to December 31, 2000, you shall not, directly or indirectly, within a 50 
mile radius of any location where Gentle Dental or any of its subsidiaries 
owns, manages, develops, or operates any dental practice or assets, engage or 
participate or make any financial investments in, or become employed by, or 
act as an agent or principal of, or render advisory or other services to or 
for, any person, firm or corporation that is engaged, directly or indirectly, 
in any line of business of Gentle Dental (a "Competing Enterprise").  A 
Competing Enterprise shall not include (i) any practice of dentistry with or 
consulting to a group of 10 or fewer dentists or (ii) any practice of 
dentistry with a group of more than 10 dentists or consulting with such a 
group on clinical matters, provided that you do not consult on or participate 
in acquisitions of dental practices or recruitment of dentists.  Similarly, 
nothing herein contained shall restrict you from engaging in the solo 
practice of dentistry.  Nothing herein contained shall restrict you from 
holding investments in not more than three percent of the voting securities 
of any Competing Enterprise whose stock is listed on a national securities 
exchange or is actively traded on the National Association of Securities 
Dealers Automated Quotation System, so long as in connection with such 
investments you do not render services to a Competing Enterprise.

     (c)   NON-DISPARAGEMENT.   You will not disparage Gentle Dental, its 
officers, directors, managers or employees, and you will not assist, support 
or cooperate with any other person or entity in asserting any type of claim 
against Gentle Dental, its officers, directors, managers or employees unless 
compelled to do so by law.  Gentle Dental will not authorize any disparaging 
statements about you, and will not assist, support or cooperate with any 
other person or entity in asserting any type of claim against you unless 
compelled to do so by law.

     (d)   CONSEQUENCES OF BREACH.  You acknowledge that damages at law would 
not be an

                                       3

<PAGE>


adequate remedy for violation of this Section 7 and you therefore agree that 
the provisions of this Section 7 may be specifically enforced against you in 
any court of competent jurisdiction.  Gentle Dental also may seek damages for 
any breach by you of this Section 7, but Gentle Dental agrees that breach of 
this Section 7 by you shall not give Gentle Dental a right to stop making 
consulting and severance payments to you.

     8.   PUBLIC ANNOUNCEMENT.  Gentle Dental will release a statement that 
you have resigned from Gentle Dental and entered into a consulting agreement 
in order to spend more time with your family and to pursue charitable 
interests.  Neither you nor Gentle Dental will make any other public 
announcements regarding the other without the prior review and approval of 
the other, except that Gentle Dental shall not be obligated to obtain your 
approval for any public announcement that Gentle Dental reasonably believes 
it is obligated to make under any law or rule applicable to it.

     9.   TERMINATION OF AFFILIATE STATUS.  For all securities law purposes, 
Gentle Dental will treat you as if you ceased to be an affiliate of Gentle 
Dental as of December 31, 1998, and will instruct its transfer agent 
accordingly in connection with any proposed sale by you of Gentle Dental 
stock or the stock of the new parent holding company resulting from Gentle 
Dental's proposed merger with Dental Care Alliance, Inc.

     10. MUTUAL RELEASE.  Except for the rights and claims created under this 
Agreement or any other agreement entered into concurrently herewith, you 
hereby waive any legal rights and release and forever discharge Gentle 
Dental, and Gentle Dental hereby waives any legal rights and releases and 
forever discharges you from any and all liability, demands, claims, suits, 
actions, charges, damages, judgments, levies or executions, whether known or 
unknown, liquidated, fixed, contingent, direct or indirect, which either 
party has, could have or could raise against the other.

     You and Gentle Dental each acknowledge the full and final waiver and 
release of all claims of every kind, nature or description whatsoever you or 
Gentle Dental has or may have against the other, specifically including but 
not limited to all claims for relief or remedy of any type under any state or 
federal laws, including but not limited to federal and state statutes and 
common law claims based on alleged breach of contract, breach of fiduciary 
duty, breach of statutory duty, misrepresentation, fraud, defamation, 
interference, negligence or tortious conduct of any type whatsoever, or any 
other common law theories. This Mutual Release specifically includes, but is 
not limited to, claims relating to civil rights, employment discrimination 
(based on race, color, age, sex, national origin, marital status, handicap, 
veteran status, religion, workers' compensation and family relationship), 
labor, employment rights or benefits, or relating to employment or 
termination of employment, wage payments, and claims for additional 
compensation, back pay or benefits of any type (except in accordance with the 
terms of the Agreement); and including but not limited to any claim for 
attorneys' fees or costs, for reinstatement or reemployment, or for 
compensatory or punitive damages under any applicable statutes or common law 
theories, except to the extent that waiver or release of future claims is 
specifically prohibited by law.

     This Mutual Release also specifically includes, but is not limited to, 
all potential claims based upon Title VII of the Civil Rights Act of 1964, 
the Post-Civil War Civil Rights Act (42 USC -Section-1981-1988), the Civil 
Rights Act of 1991, the Equal Pay Act, the Age Discrimination in Employment 
Act, the  Older Workers' Benefit Protection Act, the Worker Adjustment and

officers, directors, shareholders and assigns, and any related or successor

     Notwithstanding the foregoing, this Mutual Release shall not apply to 
your right to be paid salary and reimbursed for expenses under the Employment 
Agreement through the end of your employment, and this Mutual Release does 
not affect your rights to indemnity or insurance coverage for claims of third 
parties arising in connection with your service as an officer or director of

     11.   ADDITIONAL ACKNOWLEDGMENTS.  You acknowledge that Gentle Dental 
has no legal obligation to provide you with these separation/transition 
benefits except as part of this Agreement.  These benefits are unique to you 
and your circumstances and are in lieu of any other separation or severance 
benefits to which you might otherwise be entitled under any policy, plan or 
practice of Gentle Dental.

     You further acknowledge that this Agreement contains the entire 
agreement between you and Gentle Dental regarding the terms of your 
separation from employment.  You acknowledge that no representations have 
been made to you by Gentle Dental other than those set forth in this 
Agreement.

     You further acknowledge that you have been given at least 21 days to 
consider this Agreement and to discuss it with financial or legal counsel of

after you receive it in order for you to be entitled to the benefits given 
under it.  However, you may revoke this Agreement by sending me a written 
statement to that effect within 7 days after you have signed it.  Unless you 
revoke it, the Agreement will be effective 7 days after you have signed it; 
Gentle Dental will then provide you with the benefits stated in this 
Agreement.

     You further acknowledge that you have not filed any complaint, 
criticism, claim, charge, grievance, demand or other inquiry or proceeding 
against Gentle Dental (as defined for purposes of Section 10) with any 
governmental agency, arbitration board or association, court, administrative 
or other enforcement or adjudicative body.

     12.   SUCCESSORS AND ASSIGNS.  This Agreement shall be binding on and 
inure to the benefit of the parties hereto and their heirs, executors, legal 
representatives, successors and assigns.  Neither party shall have the right 
to assign its obligations, or all or any portion of their rights or interests 
under this Agreement without the prior written consent of the other party 
hereto, and any attempt to do so will be null and void; provided, however, 
that the rights and obligations of Gentle Dental under this Agreement and the 
Proprietary Information Agreement 

                                      5

company resulting from Gentle Dental's proposed merger with Dental Care
Alliance, Inc. at the effective time of that merger.

     13.   GOVERNING LAW.  This Agreement is made and entered into and is to 
be governed by the internal laws of the State of Washington applicable to 
agreements made and to be performed entirely within such state without regard 
to the conflicts of law principles of such state.


     14.   AGREEMENT TO ARBITRATE ANY DISPUTES.  Any controversy or claim 
arising out of or relating to this Agreement, or the breach thereof, shall be 
settled by arbitration administered by the American Arbitration Association 
in accordance with its Commercial Arbitration Rules, and judgment on the 
award rendered by the arbitrators may be entered in any court having 
jurisdiction thereof.  The arbitration panel shall be composed of three 
persons with corporate business experience in management or legal positions.  
The arbitration proceedings shall be conducted in Vancouver, Washington or 
Portland, Oregon.  The arbitrators shall have the authority to award such 
remedies or relief that a court of the state where the arbitration take place 
could order or grant in an action governed by Washington law.

     To execute this Agreement, please sign the enclosed copy where indicated 
and return the signed copy to me.

                                        Sincerely,

                                        GENTLE DENTAL SERVICE CORPORATION
