                 MERGERS PROPOSED--YOUR VOTE IS VERY IMPORTANT
 
The Boards of Directors of Gentle Dental Service Corporation and Dental Care
Alliance, Inc., have agreed on a combination of Gentle Dental Service
Corporation and Dental Care Alliance, Inc. This proposed transaction will create
one of the largest dental practice management companies in the nation. The new
company will be an effective competitor on many fronts, with affiliated dental
practices in California, Florida, Georgia, Hawaii, Idaho, Indiana, Michigan,
Oregon and Washington. We believe that this proposed combination will position
us to grow and improve our prospects as the dental practice management business
evolves and continues to consolidate.
 
In the proposed combination, Gentle Dental and Dental Care Alliance will each
become a wholly-owned subsidiary of a new corporation to be headquartered in El
Segundo, California and named "Wisdom Holdings, Inc." The new company is a
Delaware corporation. Each share of Gentle Dental common stock that you hold
will be converted automatically into the right to receive one share of common
stock of the new company. Each share of Gentle Dental preferred stock will be
converted into the right to receive one share of preferred stock of the new
company with the same rights, preferences and privileges as to the new company
as the shares of preferred stock had as to Gentle Dental. Each share of Dental
Care Alliance common stock that you hold will be converted into the right to
receive 1.67 shares of common stock of the new company. The new company will not
issue fractional shares but will pay cash instead based on the fair market value
of Gentle Dental common stock prior to the combination.
 
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 Agreement and Plan of Reorganization and Merger. 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 Agreement and Plan of
Reorganization and Merger.
 
See "Risk Factors" beginning on page 14 for a discussion of certain factors
which stockholders of Gentle Dental and Dental Care Alliance should consider in
connection with their vote.
 
The dates, times and places of the meetings are as follows:

of the Agreement and Plan of Reorganization and Merger.

OUR REASONS FOR THE MERGERS (PAGES 32 AND 33)
 
Our companies are proposing to combine because we believe that together we can
create a larger and more stable company that will provide significant benefits
to our stockholders. For instance, the larger size of the newly combined company
should help us to reduce duplicate costs. We also believe that the new company
can do a better job of increasing our revenues than we could if we did not
merge. We believe that 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 our businesses and the advice of our financial and legal
advisors and of our independent public accountants. To review our reasons for
the combination between Gentle Dental and Dental Care Alliance and the factors
we considered in greater detail, as well as how we came to agree on the
combination, please see pages   through   .

RISK FACTORS (PAGE 14)
 
In deciding whether to vote for the approval of the Agreement and Plan of

provided in the section entitled "Risk Factors" in addition to the other
information described in this Joint Proxy Statement-Prospectus.
 
THE MERGERS (PAGE 30)
 
WE HAVE ATTACHED THE AGREEMENT AND PLAN OF REORGANIZATION AND MERGER TO THIS
DOCUMENT AS APPENDIX A WHICH DESCRIBES THE COMBINATION BETWEEN OUR COMPANIES.
PLEASE READ THE 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 wholly-owned acquisition 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 the end of 1998.
 
EXCHANGE OF SHARES (PAGE 45)
 
GENTLE DENTAL SHAREHOLDERS.  As a Gentle Dental shareholder, 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.
Following the mergers, you will be entitled to exchange your shares of Gentle
Dental common stock and preferred stock for shares of the new company's common
stock or preferred stock, as the case may be, by sending your Gentle Dental
common stock and preferred stock share certificates and a form that we will send
to you to               , which will then exchange them for shares of the new
company's common stock and preferred stock, as the case may be. For more
information on how this exchange procedure works, see "Exchange of Certificates;
Fractional Shares" on page 47 of this document. For example, if you owned ten
shares of Gentle Dental common stock, after the mergers you will send in the
letter of transmittal and your old Gentle Dental certificates and in exchange
you will receive ten shares of the new company's common stock.
 
DENTAL CARE ALLIANCE STOCKHOLDERS.  As a Dental Care Alliance stockholder, 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. Following
the mergers, you will be entitled to exchange your shares of Dental Care
Alliance common stock for shares of the new company's common stock by sending
your Dental Care Alliance common stock share certificates and a form that we
will send to you to               , which will then exchange them for 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 47 of
this document. For example, if you owned ten shares of Dental Care Alliance
common stock, after the mergers you will send in the letter of transmittal and
your old Dental Care Alliance certificates and in exchange you will receive 16
shares of the new company's common stock and a check for the market value of
seven-tenths of a share of Gentle Dental common stock.
 
Shares of Gentle Dental common stock are quoted on the Nasdaq Small Cap Market.
Shares of Dental Care Alliance common stock are quoted on the Nasdaq National
Market. On October 15, 1998, the last trading day before we announced the
execution of the Agreement and Plan of Reorganization and Merger, the average of
the closing bid and ask prices of Gentle Dental common stock on the Nasdaq Small
Cap Market was $5.6875 per share and the average of the closing bid and ask
prices of Dental Care Alliance common stock on the Nasdaq National Market was
$9.6250 per

share. On            , 1998, the average of the closing bid and ask prices of
Gentle Dental common stock on the Nasdaq Small Cap Market was $     per share
and the average of the closing bid and ask prices of Dental Care Alliance common
stock on the Nasdaq National Market was $     per share.
 
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 stock broker, in major newspapers such as THE
WALL STREET JOURNAL and on the Internet.
 
In addition, each share of Gentle Dental preferred stock that is outstanding
immediately prior to the completion of the mergers will become one share of
preferred stock of the new company having the same terms.

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
 
                                       4
<PAGE>
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. For example, we believe that the combination will allow us
to eliminate certain duplicate expenses. We also expect to recognize a one-time
charge to earnings related to expenses and costs of integrating our two
companies in the year in which we complete the mergers.
 
WHAT WE NEED TO DO TO COMPLETE THE MERGERS (PAGE 51)
 
The completion of the mergers depends on a number of conditions being met. In
addition to our compliance with the Agreement and Plan of Reorganization and
Merger, these include:
 
- - Approval of the Agreement and Plan of Reorganization and Merger by both the
  Gentle Dental shareholders and the Dental Care Alliance stockholders.
 
- - Approval of certain federal and state regulatory authorities as to certain
  transactions contemplated by the Agreement and Plan of Reorganization and
  Merger and expiration of all applicable statutory waiting periods.
 
- - Receipt by each of Gentle Dental and Dental Care Alliance of a legal opinion
  that, for United States federal income tax purposes, Gentle Dental
  shareholders and Dental Care Alliance stockholders who exchange their shares
  for shares of the new company's common or preferred stock, as applicable, will
  not recognize any gain or loss as a result of the mergers, except in
  connection with the payment of cash instead of fractional shares. These
  opinions will be subject to various limitations and we recommend that you read
  a fuller description of tax consequences provided in this document on page
     .
 
- - Receipt of letters from our independent accountants that the mergers will
  qualify for "pooling of interests" accounting treatment. While our companies'
  receipt of such letters are a condition to completion of the mergers, there is
  no assurance that the Securities and Exchange Commission will not come to a
  different conclusion which would require the new company to account for the
  mergers under the purchase method of accounting.
 
- - Approval by the Nasdaq National Market of the listing of shares of the new
  company's common stock to be issued as a result of each merger.
 
- - The absence of any injunction or legal restraint blocking either merger or
  government proceedings trying to block either merger.
 
- - Entering into employment agreements with certain officers and certain other
  agreements.
 
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 AGREEMENT; EXPENSES (PAGE 56)
 
We can agree at any time to terminate the Agreement and Plan of Reorganization
and Merger 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 Agreement and Plan of Reorganization and Merger
if:
 
- - Any government agency denies an approval we need to compete the mergers, and
  that denial has become final and nonappealable, or if any governmental entity
  issues a final, non-appealable order blocking the mergers.
 
- - The mergers have not been completed by March 31, 1999, unless the failure to
  complete the mergers by that time is due to a knowing action or inaction in
  violation of the Agreement and Plan of Reorganization and Merger to the
  detriment of the other party by the party that wants to terminate the
  agreement.
 
- - The other party breaches our agreement (and does not correct the breach
  properly) in a way that would entitle the party that wants to terminate the
  agreement to not complete the mergers, as long as the party looking to
  terminate the
 
                                       5
<PAGE>
  agreement has not materially breached the agreement.
 
- - Our stockholders do not approve the mergers.
 
- - One party accepts an acquisition proposal from a third party, fails to
  recommend the mergers to its stockholders or withdraws or modifies a
  recommendation in a manner adverse to the other party.
 
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 Agreement and Plan of Reorganization and Merger 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. However, if either of our board 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.
 
STOCKHOLDERS' AGREEMENT (PAGE 60)
 
Certain officers, directors and significant shareholders of Gentle Dental and
certain officers and directors of Dental Care Alliance have entered into a
Stockholders' Agreement in which they have agreed to vote "FOR" adoption and
approval of the Agreement and Plan of Reorganization and Merger. 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.
 
WAIVER AND AMENDMENT (PAGE 57)
 
We can agree to amend the Agreement and Plan of Reorganization and Merger, and
each of us can waive our right to require the other party to adhere to the terms
and conditions of the 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.
 
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.
 
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.

<PAGE>
INTERESTS OF DIRECTORS AND OFFICERS IN THE MERGER THAT ARE DIFFERENT FROM YOUR
INTERESTS (PAGE 58)
 
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 agreement 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 Merger--Interests of Certain Persons in the Merger"
at page    of this document. The members of our boards knew about these
additional interests, and considered them, when they approved the Agreement and
Plan of Reorganization and Merger.
 
APPRAISAL RIGHTS (PAGE 113)
 
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 and NOT VOTING YOUR SHARES IN FAVOR OF THE MERGERS. 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.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES (PAGE 54)
 
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.
 
Our obligation to complete the mergers depends on our receipt of 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 SHOULD CONSULT
YOUR OWN TAX ADVISOR FOR A FULL UNDERSTANDING OF THE TAX CONSEQUENCES OF THE
MERGERS.
 
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 Care Alliance Restated Certificate of Incorporation
and the Dental Care Alliance By-laws. Upon our completing the combination of our
companies, 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.

                 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.
 
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 that we have presented in our prior Securities and Exchange
Commission filings, which is included elsewhere in this Joint Proxy
Statement-Prospectus.

          SUMMARY CONSOLIDATED PRO FORMA FINANCIAL AND OPERATING DATA
                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
    The following consolidated 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
consolidated 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 consolidated pro forma 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 pooling
of interests mergers between Gentle Dental Service Corporation and Dental Care
Alliance, Inc. as if they had merged on January 1, 1995. The pro forma financial
data for the years ended December 31, 1997 and the six months ended June 30,
1998 include the results of all practices acquired (from an accounting point of
view) or expected to be acquired by the companies as if they 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
consolidated pro forma 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,
nor are the statements necessarily indicative of the 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 Proxy Statement-Prospectus,
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.
 
ABILITY TO INTEGRATE THE OPERATIONS OF GENTLE DENTAL AND DENTAL CARE ALLIANCE;
  RAPID GROWTH
 
    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. In addition, there
is no assurance that we will be able to successfully integrate the
administrative operations of Gentle Dental and Dental Care Alliance or that such
operating efficiencies or successful integration will be realized in the time
frame currently anticipated.
 
    Gentle Dental and Dental Care Alliance each are experiencing a period of
rapid growth with a substantial increase in the number of dental practices we
manage. Our strategy will call for future growth, partly through affiliations
with additional dental practices. These affiliations will place strains on the
new company's management, operations and systems. Our ability to manage our
growth and compete effectively will depend upon our ability to hire, train and
assimilate additional management and other employees and to expand, improve and
effectively utilize our operating, management, marketing, information and
financial systems to accommodate expanded operations. Any failure by our
management to anticipate, implement and manage effectively the changes required
to sustain growth, may have a material adverse effect on the new company's
business, financial condition and results of operations.
 
    Our expansion into new markets will require us to maintain and establish
payor and customer relationships and to convert the patient tracking and
financial reporting systems of new dental practices to our systems. Significant
delays or expenses with regard to this process could have a material adverse
effect on the integration of additional dental practices and on the new
company's business, financial condition and results of operations. There can be
no assurance that we will be able to maintain or establish payor and customer
relationships, convert management information systems or integrate new practices
into our combined network.
 
    The integration of additional dental practices typically requires the
implementation and centralization of purchasing, accounting, human resources,
management information systems, cash management and other systems, which may be
difficult, costly and time-consuming. Our operating results in fiscal quarters
immediately following a new dental practice affiliation may be adversely
affected while we attempt to complete the integration process. We may encounter
significant unanticipated costs or other problems associated with the
integration of future affiliations into our combined network of affiliated
dental practices. There can be no assurance that future affiliations will not
have a material adverse effect on the new company's business, financial
condition and results of operations, particularly during the period immediately
following completion of such affiliations.
 
                                       14
<PAGE>
EXPANSION PROGRAM
 
    One of our primary business strategies will be to increase revenue and
expand the markets we serve by acquiring certain operating assets and entering
into long-term management service agreements with additional dental practices.
Our strategy will include growth through affiliation with dental practices in
areas where Gentle Dental and Dental Care Alliance currently operate and in new
markets. The success of our affiliation strategy will depend on a number of
factors, including (i) regulatory requirements, (ii) the availability of
financing to fund the affiliation strategy on acceptable terms, (iii) the
ability to successfully integrate additional dentists and dental practices or
offices, (iv) the ability to affiliate with dentists to open new dental sites
and the ability to obtain locations in suitable markets, and (v) the ability to
identify and affiliate with suitable existing dental practices on favorable
terms. Competition for such affiliations has increased significantly in recent
years and may increase further in the future due to ongoing consolidation in the
dental practice management services industry. As a result of such competition,
there may be fewer attractive affiliation opportunities than we have encountered
in the past, or the price of affiliations may increase significantly. In
implementing our affiliation strategy, we will compete with other dental
practice management companies, some of which may have greater financial
resources. No assurances can be given that we will be able to complete the
affiliations necessary for our expansion plans, that such affiliations will be
on favorable terms, or that we will be able to successfully integrate newly
affiliated dental practices. Failure to complete future affiliations or to
successfully integrate dental practices could have a material adverse effect on
the new company's business, financial condition and results of operations.
 
    We may in the future enter new markets in which we will have limited or no
previous presence or experience. Our past experience reflects initial periods in
which certain dental practices within new geographic markets contribute
minimally to operating results. Initial profitability, if any, at the regional
level may be low because of the time and capital required to develop a network
of offices and practitioners.
 
    We will devote substantial time and resources to identifying potential
affiliation targets, negotiating terms of affiliations and integrating dental
practices into our combined network, all of which may distract management
resources from the day-to-day operations of the new company. Delays in
completing affiliations could cause fluctuations in quarterly earnings and
corresponding fluctuations in the market price of the new company's common
stock. Further, the financial results and the market value of the new company's
common stock in the fiscal quarters immediately following an affiliation may be
adversely affected during the period in which we are implementing our operating
model at newly affiliated dental practices. We intend to use the new company's
common stock as part of the consideration for affiliations with additional
dental practices. There can be no assurance that fluctuations in the market
price of the new company's common stock will not adversely affect our ability to
use common stock for affiliations. In addition, the issuance of common stock as
part of the purchase price for new affiliations will result in dilution of the
beneficial ownership interests and voting power of the holders of the new
company's common stock prior to the completion of such affiliations.
 
RISKS ASSOCIATED WITH EXPANSION WITHIN EXISTING MARKETS
 
    We will also seek to increase revenue and profitability in existing markets
by expanding the operations of existing affiliated dental practices by adding
more general dentists, specialists and hygienists, by establishing new dental
offices and by improving the efficiency of the existing affiliated dental
practices. We will be subject to risks associated with this growth strategy,
including the risk that we will be unable to successfully expand the operations
of the affiliated dental practices, establish new dental offices or increase
efficiency through management of existing affiliated dental practices. In
addition, establishing new dental offices will require significant capital
expenditures to furnish the new offices with appropriate equipment, materials
and supplies and such offices may be staffed with one or more dentists who have
no existing patient base and, as a result, may require us to make significant
advertising and marketing expenditures to attract patients on behalf of such
offices.
 
                                       15
<PAGE>
ADDITIONAL MANAGEMENT AND STAFFING OF DENTAL PRACTICES
 
    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.
 
AVAILABILITY OF 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.
These requirements may cause us to incur long-term and short-term indebtedness
or result in the public or private issuance, from time to time, of additional
equity or debt securities. 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. In addition, offerings of equity securities other than common
stock could be required to the extent that the new company's common stock fails
to maintain a market value sufficient to warrant its use for future financing
needs. 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.
 
DEPENDENCE ON 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 practices of our affiliated
dentists. Our profitability will be dependent on the revenue and expenses of the
affiliated dental practices and, therefore, the performance of these dental
practices will be essential to the new company's success. Revenue and expenses
of the affiliated dental practices are affected by a number of factors,
including the ability to attract and retain high quality dental practitioners
and other personnel, marketing, pricing, patient visits, compensation expenses
and other expenses of these dental practices. From time to time, we enter into
or amend management agreements and the affiliated dental practices enter into or
amend employment agreements, which have a material impact on certain of these
factors. 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 1.9% of the
new company's pro forma revenues for the year ended December 31, 1997, and 1.7%
of its pro forma revenues for the six months ended June 30, 1998, terminate
between 1998 and 2005. Any material loss of revenue or increase in the expenses
of the affiliated dental practices or the expiration and termination of
management agreements could have a material adverse effect on the new company.
 
                                       16

RISKS ASSOCIATED WITH NOTES, ADVANCES AND MANAGEMENT FEE RECEIVABLES FROM
  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 dental practices under management. These loans are evidenced by notes
and secured by the dental assets of such dental practices under management, some
of which are intangible and not readily convertible into cash, and are
personally guaranteed by the dentists who own the affiliated dental practices.
Such loans are recorded on Dental Care Alliance's balance sheet as "Notes
Receivable from PAs" until repaid. At December 31, 1997 and June 30, 1998, Notes
Receivable from PAs were $914,026 and $3,104,027, respectively. 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, in the event that the percentage of
revenue retained by any affiliated dental practices after payment of management
fees to the new company is not sufficient to pay its expenses, as is often the
case with newly integrated dental practices under management and occurs from
time to time with other dental practices under management, the new company may
elect to advance funds to cover such expenses. Such advances are recorded on
Dental Care Alliance's balance sheet as "Advances to PAs" until repaid. At
December 31, 1997 and June 30, 1998, Advances to PAs were $483,421 and
$1,361,517, respectively. 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 results of operations and financial condition. Further, any decision
by the new company to continue to make loans or advances to affiliated dental
practices or the sustained inability of affiliated dental practices to collect
patient receivables with the result that the relevant affiliated dental practice
is unable to pay its 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
which events could have a material adverse effect on the new company's 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 herein.
 
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.
 
    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.
 
    Although we believe that the Gentle Dental and Dental Care Alliance
operations comply in all material respects with the above-described laws to
which they are subject, there can be no assurance that a
 
                                       17
<PAGE>
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. 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.  Federal law prohibits the offer, payment, solicitation or receipt of any
form of remuneration in return for or in order to induce (i) the referral of a
person for services; (ii) the furnishing or arranging for the furnishing of
items or services; or (iii) 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.
 
    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.
 
    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
 
                                       18
<PAGE>
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 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"). 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., a wholly owned subsidiary of Gentle
Dental, and Capitol Dental Care, Inc., a pending Gentle Dental acquisition,
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, and generate periodic financial reports
for submission to the Office of Medical Assistance Programs. They are also
required to establish and maintain restricted reserve funds and maintain net
worth in contractually specified amounts. Failure to maintain adequate financial
solvency or otherwise comply with contractual terms 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 10.7% of its pro forma revenues for the six
months ended June 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
 
                                       19
<PAGE>
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 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.
 
DEPENDENCE ON THIRD-PARTY PAYORS; RISKS ASSOCIATED WITH MANAGED CARE
 
    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 payments 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 of these agreements could materially and
adversely affect the new company's business, financial condition and results of
operations.
 
    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
("HMOs"), 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, which 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, and 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.
 
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.
 
                                       20
<PAGE>
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. We believe that cost, location,
hours of operation and quality of dental services are the principal factors
affecting competition for patients. We expect that the ability to meet the needs
of managed care payors will increasingly be a factor in competing for patients
covered by managed care reimbursement arrangements. 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
materially adversely affect the new company's business, financial condition and
results of operations.
 
DEPENDENCE UPON 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.
 
AVAILABILITY OF DENTAL PROFESSIONALS
 
    Our business is dependent on the recruitment and retention of general
dentists, specialists, hygienists and dental assistants to join the affiliated
dental practices. While Gentle Dental and Dental Care Alliance have been
successful in assisting their affiliated dental practices with recruiting and
retaining such professionals, no assurances can be given that we will be able to
continue to do so on terms similar to current arrangements. Substantially all
dentists practicing within the Gentle Dental and Dental Care Alliance networks
of affiliated dental practices have entered into employment or similar
agreements or independent contractor agreements with their affiliated dental
practices. Such agreements typically contain noncompetition agreements following
termination of the employment agreement within a specified geographic area,
usually a specified number of miles from the offices of the relevant affiliated
dental practices. Although Wisdom Holdings, in conjunction with the affiliated
dental practices, endeavors to maintain and renew agreements with affiliated
dentists, in the event that a significant number of such dentists terminate or
do not renew such agreements, or in the event the non-competition agreements are
determined to be unenforceable or more limited in scope than their terms, the
new company's business, financial condition and results of operations could be
materially and adversely affected.
 
RISKS 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 June 30, 1998, on a pro forma basis,
the new company would have had approximately $159.0 million of total assets (of
which approximately $93.7 million were intangible assets) and approximately
$68.1 million in total stockholders' equity. We expect such amounts 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 value
of the management agreements will be realized. When factors indicate that the
amount allocable to one or 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 reduction is recognized.
 
                                       21
<PAGE>
    The new company will own all or substantially all of the operating assets
used by the affiliated dental practices it manages but, except as permitted by
law, will not employ or contract with dentists, or control the provision of
dental care. Therefore, effective and continued performance of dentists
providing services for affiliated dental practices is essential to the new
company's long-term success. Because we derive our revenues through management
agreements, any material decline in revenue by one or more affiliated dental
practices could have a material adverse effect on the new company's business,
financial condition and results of operations, and any management agreement
termination by one of the affiliated dental practices could have such a material
adverse effect on the new company's business, financial condition and results of
operations. In the event of a breach of a management agreement by any affiliated
dental practice, there can be no assurance that the legal remedies available to
the new company will be adequate to compensate it or cover its damages resulting
from such breach.
 
POTENTIAL LIABILITY AND INSURANCE
 
    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 medical
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.
 
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
 
    Sales of substantial amounts of the new company's common stock in the public
market following the mergers could adversely affect the price of its common
stock. 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.
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. 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.
 
                                       22
<PAGE>
COMMON STOCK PUT RIGHTS
 
    A total of 180,712 shares of the new company's common stock that is expected
to be issued in the mergers (as well as 100,000 shares of the new company's
common stock that will be subject to a warrant granted to ServiceMaster Venture
Fund, L.L.C. in 1995 by Gentle Dental and which will be assumed by the new
company in the merger) will be subject to certain "put" rights described below
to be assumed by the new company in the mergers. Of these, put rights issued to
dentists in connection with Gentle Dental affiliations cover a total of 80,712
shares. These put rights will give the holders the right to require the new
company to repurchase shares of the new company's common stock at prices ranging
from $13.38 to $19.62 per share. One such holder will have assumed put rights
with respect to 11,820 shares that can be exercised in varying amounts in 1999
and 2000. All other dentist put rights to be assumed will become exercisable
between January 2000 and January 2003 and will expire if not exercised within 60
days of the exercise date. The dentist put rights with respect to all but 20,000
shares will terminate if the new company completes a public offering of its
common stock at a price greater than $20.00 per share. Pursuant to the terms of
these dentist put rights, the new company could be required to repurchase 2,754
shares of the new company's common stock at an aggregate purchase price of
approximately $50,000 in 1999, 40,849 shares of its common stock at an aggregate
purchase price of approximately $576,000 in 2000, 29,681 shares of its common
stock at an aggregate purchase price of approximately $438,000 in the year 2001,
and 3,714 shares of its common stock at an aggregate purchase price of
approximately $51,000 in each of 2002 and 2003. The new company will also assume
a put right granted to ServiceMaster which will allow ServiceMaster to require
Wisdom Holdings to repurchase 100,000 shares currently held by Service Master
and an additional 100,000 shares ServiceMaster may acquire upon exercise of a
warrant, if by June 21, 2001, the new company has not made a public offering of
its common stock with a per share price of at least $22.00 and net proceeds to
the new company of at least $10 million. This put right may not be exercised
before June 21, 2001, and will expire upon the earlier of the completion of a
public offering meeting the requirements previously described or June 21, 2003.
The per share price applicable to ServiceMaster's put right is 20 times the new
company's average adjusted net income per share on a pro forma basis, giving
effect to the mergers, for the two most recent fiscal years preceding
ServiceMaster's exercise of the right.
 
    Shares subject to put rights are classified as "redeemable common stock" on
the new company's pro forma balance sheet. If holders of the new company's
common stock subject to put rights elect to exercise those rights, the new
company will have to pay those holders the applicable repurchase price in cash
in exchange for the delivery of the holders' shares, and such an election could
have a material adverse effect on the new company's business, financial
condition and operating results. There can be no assurance that the new company
will have sufficient capital resources to honor the outstanding put rights and
the new company's use of cash to honor outstanding put rights would also reduce
funds otherwise available to it for operations or future dental practice
affiliations.
 
NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
 
    Prior to the mergers, there has been no public market for the new company's
common stock and 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 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
 
                                       23
<PAGE>
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 Delaware 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 Wisdom
Holdings.
 
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 the dental practice management
business is dependent on computer applications, such as management information
systems and financial and accounting systems. Based upon confirmations received
from significant management information systems and financial and accounting
systems software licensors, certain of our significant systems are currently
Year 2000 compliant or are expected to be Year 2000 compliant by April 1999. We
are in the process of verifying that our other management information systems
and financial and accounting systems will be Year 2000 compliant. We expect that
we may have to incur internal staff costs as well as consulting and other
expenses related to Year 2000 system preparations. As part of these
preparations, we have contacted or intend to contact vendors, third-party and
governmental payors and other third parties upon whose services we rely to
ensure Year 2000 compliance. We have contacted certain of our significant
vendors who 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 or of our management information systems or financial or accounting
systems 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.

1998, and is accompanied by the notice of the Special Meeting of Shareholders of
Gentle Dental (the "Gentle Dental Special Meeting") and a form of proxy that is
solicited by the Board of Directors of Gentle Dental (the "Gentle Dental Board")
for use at the Gentle Dental Special Meeting to be held on            , 1998, at
  a.m., local time,           , Los Angeles, California, and at any adjournments

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 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

additional votes to approve the 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

therein. If nothing is specified, the proxies will be voted in favor of the
approval of the Agreement and the transactions contemplated thereby. The Gentle
Dental Board 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 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.
 
                                       25

RECORD DATE AND VOTING RIGHTS
 
    Pursuant to the provisions of the Washington Business Corporation Act (the
"Washington Law"), and the rules of the Nasdaq Small Cap Market,            ,
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 (the "Gentle Dental Record Date"). 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 and Gentle Dental Series C Preferred at the Gentle
Dental Record Date will be entitled to notice of and to vote at the Gentle
Dental Special Meeting regarding the 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 held by
one holder of record, 100 shares of Gentle Dental Series C Preferred held by one
holder of record and       shares of Gentle Dental Series D Preferred 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 Captial 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 voted in matters where discretionary voting by the broker is
not allowed ("broker non-votes").
 
    The affirmative vote of a majority of the outstanding shares of Gentle
Dental Common Stock and Gentle Dental Series D Preferred entitled to vote,
voting together as single class, is required to approve the 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, Gentle
Dental Series C Preferred and Gentle Dental Series D Preferred entitled to vote,
voting as separate classes, is required to approve the Agreement and the
transactions contemplated thereby. Each share of Gentle Dental Capital Stock is
entitled to one vote regarding the Agreement and the transactions contemplated
thereby.
 
    ABSTENTIONS AND BROKER NON-VOTES WILL HAVE THE SAME EFFECT AS VOTES AGAINST
APPROVAL OF THE AGREEMENT. ACCORDINGLY, THE GENTLE DENTAL BOARD 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, representing all of the Series A preferred
stock entitled to vote, 100 shares of Gentle Dental Series C Preferred,
representing all of the Gentle Dental Series C Preferred entitled to vote, and
      shares of Gentle Dental Series D Preferred, representing approximately
   % of the Gentle Dental Series D Preferred 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.

    This section of the Joint Proxy Statement-Prospectus describes certain
aspects of the Mergers, including the material provisions of the Agreement.
Certain capitalized terms used herein without definition shall have the meanings
ascribed to them in the Agreement.
 
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 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 believed
that Dental Care Alliance's planned expansion of its business could be enhanced
significantly through strategic
 
                                       30
<PAGE>
combinations with appropriate existing dental practice management companies. The
Dental Care Alliance Board 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 the respective companies 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 problems and
differences in business philosophy. No discussions are ongoing at this time.
 
    On July 15, 1998, Mr. Fiore, Dr. Matzkin and certain members of the Gentle
Dental Board and the Dental Care Alliance Board 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
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 for each of Gentle Dental and Dental Care
Alliance 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 retained Salomon Smith Barney Inc. as its financial
advisor, and Dental Care Alliance retained Raymond James & Associates, Inc. as
its financial advisor.
    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 each of Gentle
Dental and Dental Care Alliance 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
 
                                       31
<PAGE>
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 Donaldson, Lufkin and Jenrette Securities Corporation
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 their findings to
their 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 other of the company. On October 13, 1998, the Board of Directors
of Dental Care Alliance met to discuss and review the terms of the proposed
business combination of the two companies and the various transactions
contemplated as a result of the combination. The Dental Care Alliance Board 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 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
reviewed in detail the terms of the proposed combination and the fairness
opinion provided by Salomon Smith Barney Inc. regarding the fairness of the
Gentle Dental Exchange Ratio to the shareholders of Gentle Dental as
contemplated by the Agreement. After a discussion and review of the terms of the
Agreement and the related documents previously presented to the Gentle Dental
Board, the Gentle Dental Board approved and authorized the execution of the
Agreement and the related agreements and transactions contemplated thereby.
 
    On October 15, 1998, the Dental Care Alliance Board 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 also
reviewed the fairness opinion provided to Dental Care Alliance by Raymond James
& Associates, Inc. regarding the fairness of the Dental Care Alliance Exchange
Ratio to the stockholders of Dental Care Alliance as contemplated by the
Agreement. After further discussion and review of the terms of the Agreement and
the related documents previously presented to the Dental Care Alliance Board,
the Dental Care Alliance Board authorized and approved the execution of the
Agreement and the related agreements and transactions contemplated thereby.
 
    During the evening of October 15, 1998, the parties executed the Agreement
and the parties announced the proposed business combination on the morning of
October 16, 1998.
 
RECOMMENDATION OF THE GENTLE DENTAL BOARD AND REASONS FOR THE MERGER
 
    The Gentle Dental Board believes that the Gentle Dental Merger is fair to,
and in the best interests of, Gentle Dental and the Gentle Dental shareholders.
Accordingly, the Gentle Dental Board has approved the Agreement, and recommends
that the Gentle Dental shareholders vote for the approval and adoption of the
Agreement, the Gentle Dental Merger and the agreements and transactions
contemplated thereby.
 
    The Gentle Dental Board believes that the consummation of the Gentle Dental
Merger 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 Agreement, the Gentle Dental Merger
and the agreements and transactions contemplated thereby, the Gentle Dental
Board consulted with Gentle Dental's management, as well as with its financial
and legal advisors and considered a variety of factors, including the following:
 
    - The Gentle Dental Board's 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 Gentle Dental Board
      took into account the results of Gentle Dental's due diligence review of
      Dental Care Alliance's business.
 
    - 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 and
      elimination of duplicative corporate expenses, increased access to capital
      and increased attractiveness to dental practices which are affiliation
      candidates.
 
    - The structure of the combination and the terms of the Agreement and the
      Stockholders' Agreements, which were reciprocal in nature, including the
      fact that the fixed Gentle Dental Exchange Ratio 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 the
      Gentle Dental Merger is intended to qualify as either a reorganization
      under Section 368(a) of the Internal Revenue Code of 1986, as amended (the
      "Code"), 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-
      Chairman, President and Chief Dental Officer of the combined company after
      the Mergers. See "Management and Operations after the Merger."
 
    - The written opinion of Salomon Smith Barney Inc. that, as of October 15,
      1998, the Gentle Dental Exchange Ratio was fair from a financial point of
      view to the shareholders of Gentle Dental. See "--Opinion of Gentle
      Dental's Financial Advisors."
 
    - The belief of Gentle Dental's senior management and the Gentle Dental
      Board that Gentle Dental and Dental Care Alliance share a compatible
      business culture and that their respective managements possess
      complementary skills and expertise.
 
    The foregoing discussion of the information and factors considered by the
Gentle Dental Board is not intended to be exhaustive but includes all material
factors considered by the Gentle Dental Board. In reaching its determination to
approve and recommend the Mergers, the Gentle Dental Board 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
recommends that Gentle Dental shareholders vote for approval and adoption of the
Agreement.
 
RECOMMENDATION OF THE DENTAL CARE ALLIANCE BOARD AND REASONS FOR THE MERGER
 
    The Dental Care Alliance Board has approved and adopted the Agreement and
believes that the Dental Care Alliance Merger is fair to and in the best
interests of Dental Care Alliance and its stockholders. Accordingly, the Dental
Care Alliance Board has unanimously approved the Agreement and
 
                                       33
<PAGE>
unanimously recommends that the stockholders vote for the approval of the
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 Dental Care Alliance Merger, including the Dental Care
Alliance Exchange Ratio, are the result of arm's length negotiations between
representatives of Gentle Dental and Dental Care Alliance. In reaching its
decision to approve the Agreement, the Dental Care Alliance Board, 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 Dental Care Alliance Exchange Ratio. The Dental Care Alliance
Board concluded that the Dental Care Alliance Merger is 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 Agreement and to recommend
to its stockholders the adoption of the Agreement, the Dental Care Alliance
Board considered a number of factors, both from a short-term and long-term
perspective, including, without limitation, those set forth in "Background of
the Merger," "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 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 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 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 Dental Care Alliance Exchange Ratio was fair to
      the stockholders of Dental Care Alliance from a financial point of view.
      See "--Opinion of Dental Care Alliance's Financial Advisor."
 
                                       34
<PAGE>
    - The Dental Care Alliance Board's belief that the analyses of Raymond James
      & Associates, Inc. supported the Dental Care Alliance Board's conclusion
      that the Dental Care Alliance Merger is 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 Dental Care Alliance Board that the receipt of the new
      company's common stock in the Dental Care Alliance Merger 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").
 
    In view of the variety of factors considered by the Dental Care Alliance
Board in connection with its evaluation of the Dental Care Alliance Merger, the
Dental Care Alliance Board 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 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 instructed Salomon Smith Barney Inc. to
evaluate the fairness, from a financial point of view, of the Gentle Dental
Exchange Ratio. At the October 14, 1998 meeting of the Gentle Dental Board,
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
Gentle Dental Exchange Ratio was fair, from a financial point of view to Gentle
Dental's shareholders.
 
    THE FULL TEXT OF SALOMON SMITH BARNEY INC.'S WRITTEN OPINION DATED OCTOBER
15, 1998 IS ATTACHED AS APPENDIX B TO THIS JOINT PROXY STATEMENT-PROSPECTUS 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 JOINT PROXY STATEMENT-PROSPECTUS 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, of the Gentle Dental Exchange Ratio 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 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
Gentle Dental Merger and participated in discussions concerning the
determination of the Gentle Dental Exchange Ratio, Salomon Smith Barney Inc. was
not asked to and did not recommend the Gentle Dental 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: (i) reviewed the Agreement; (ii) 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; (iii) examined certain publicly available business and
financial information relating to Gentle
 
                                       35
<PAGE>
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 Gentle Dental Merger; (iv) reviewed the financial terms of
the Gentle Dental Merger as set forth in the 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; (v) 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; (vi) evaluated the potential
pro forma financial impact of the Mergers on Gentle Dental; and (vii) conducted
such other studies, analyses, inquiries and investigations as Salomon Smith
Barney Inc. 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, 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
of 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 as to the fairness, from a financial point of view, of the Gentle
Dental Exchange Ratio. As described above, certain
 
                                       36
<PAGE>
of the analyses performed by Salomon Smith Barney Inc. relied on estimates of
future financial performance provided by the managements of Gentle Dental and
Dental Care Alliance. Analyses based on forecasts of future results are not
necessarily indicative of actual future results, and may be significantly more
or less favorable than suggested by such analyses. 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 their accuracy.
 
    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 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. (the "Selected Companies").
Salomon Smith Barney Inc. compared market values (as of October 10, 1998) as a
multiple of estimated calendar years 1998 and 1999 earnings per share ("EPS"),
and enterprise value (market value, plus total debt, less cash) as a multiple of
last 12 months ("LTM") earnings before interest, taxes, depreciation and
amortization ("EBITDA"), last quarter annualized ("LQA") EBITDA, and 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 were obtained from reports published by the First Call Corporation.
 
    Applying the foregoing high and low range of multiples for the Selected
Companies to corresponding financial data for Dental Care Alliance of (i)
estimated calendar 1998 EPS of 15.3x to 20.7x resulted in an equity reference
range for Dental Care Alliance of approximately $7.96 to $10.76 per share, (ii)
estimated calendar 1999 EPS of 10.5x to14.3x resulted in an equity reference
range for Dental Care Alliance of approximately $7.59 to $10.27 per share, (iii)
LTM EBITDA of 8.5x to 11.5x resulted in an equity reference range for Dental
Care Alliance of approximately $4.56 to $5.82 per share, (iv) LQA EBITDA of 7.1x
to 9.5x resulted in an equity reference range for Dental Care Alliance of
approximately $6.82 to $8.88 per share, and (v) pro forma LQA EBITDA of 7.1x to
9.5x resulted in an equity reference range for Dental Care Alliance of
approximately $8.47 to $11.11 per share.
 
    Salomon Smith Barney Inc. noted that none of the Selected Companies was
identical to Dental Care Alliance and that, accordingly, any analysis of the
Selected Companies necessarily involved complex considerations and judgments
concerning differences in financial and operating characteristics and other
factors that would necessarily affect the public trading values of the Selected
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 dental practice management industry since November 1996 (the
"Selected Transactions"). The 12 transactions included in the Selected
Acquisitions were: (i) the acquisition of Valley Forge Dental Associates. Inc.
by Monarch Dental Corporation; (ii) the acquisition of MedCath Incorporated by
KKR 1996 Fund, L.P. and Welsh, Carson, Anderson & Stowe VII, L.P.; (iii) the
acquisition of First Physician Care, Inc. by PhyCor, Inc.; (iv) the acquisition
of Spectrum Emergency Care, Inc. by Laidlaw Inc.; (v) the acquisition of Talbert
Medical Management Holdings Corporation by MedPartners, Inc.; (vi) the
acquisition of Health Partners, Inc. by FPA Medical Management, Inc.; (vii) the
acquisition of EmCare Holdings Inc. by Laidlaw Inc.; (viii) the acquisition of
OccuSystems, Inc. by CRA Managed Care, Inc.; (ix) the acquisition of InPhyNet
Medical Management Inc. by MedPartners, Inc.; (x) the
 
                                       37
<PAGE>
acquisition of American Ophthalmic Incorporated by Physicians Resource Group,
Inc.; (xi) the acquisition of AHI Healthcare Systems, Inc. by FPA Medical
Management, Inc. and (xii) the acquisition of STAT Healthcare, Inc. by American
Medical Response, Inc.
 
    Salomon Smith Barney Inc. compared purchase prices in the 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 Selected Transactions were based on information
available at the time of announcement of the 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). Applying the foregoing
high and low range of multiples for the Selected Transactions to corresponding
financial data for Dental Care Alliance of (i) LTM net income of 30.4x to 41.2x
resulted in an equity reference range for Dental Care Alliance of $8.16 to
$11.04 per share, (ii) LTM EBIT of 17.7x to 23.9x resulted in an equity
reference range for Dental Care Alliance of $7.15 to $9.33 per share, (iii) LTM
EBITDA of 11.7x to 15.9x resulted in an equity reference range for Dental Care
Alliance of $5.92 to $7.67 per share, (iv) LQA EBITDA of 12.6x to 17.0x resulted
in an equity reference range for Dental Care Alliance of $11.39 to $15.07 per
share and (v) estimated calendar year 1998 EPS of 21.1x to 28.5x resulted in an
equity reference range for Dental Care Alliance of $10.96 to $14.83 per share.
 
    Salomon Smith Barney Inc. noted that none of the Selected Transactions was
identical to the transactions contemplated by the Agreement and that,
accordingly, and analysis of the Selected Transactions necessarily involved
complex considerations and judgments concerning differences in the financial and
operating characteristics and other factors that would necessarily affect the
value of Dental 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 (the
"Acquisition Scenario") and the other assuming that such acquisitions were not
consummated (the "Base Scenario").
 
    For the Base Scenario, this analysis indicated (i) 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%, (ii) 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 (iii) 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%. For the Acquisition
Scenario, this analysis indicated (i) 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%, (ii) 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 (iii) 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 (i) 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 (ii) 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 Gentle Dental Exchange Ratio,
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
banking firm and was engaged as financial advisor to Gentle Dental in connection
with the Mergers because of its experience and expertise and its familiarity
with Gentle Dental. As part of its investment banking business, Salomon Smith
Barney Inc. is regularly engaged in the valuation of businesses and their
securities in connection with the mergers and acquisitions, negotiated
underwritings, competitive biddings, secondary distributions of listed and

other purposes.
 
    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 of the Mergers. The fee payable to
Salomon Smith Barney Inc. is currently estimated to be approximately $1.0

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 Salomon Smith Barney Inc. and related persons
against certain liabilities, including liabilities under the federal securities
laws, arising out of Salomon Smith Barney Inc.'s engagement. Salomon Smith
Barney Inc. and its affiliates may actively trade or hold the securities of
Gentle Dental and Dental Care Alliance for their own account or for the account
of customers and, accordingly, may at any time hold a long or short position in
such securities.
 
    Salomon Smith Barney Inc. has in the past provided investment banking
services to Gentle Dental unrelated to the Mergers, for which services Salomon
Smith Barney Inc. has received compensation. In addition, Salomon Smith Barney
Inc. and its affiliates (including Citigroup Inc. and its affiliates) may
maintain relationships with Gentle Dental or Dental Care Alliance.
 
OPINION OF DENTAL CARE ALLIANCE'S FINANCIAL ADVISORS
 
    Pursuant to an engagement letter dated August 22, 1998, Dental Care Alliance

whether the Dental Care Alliance Exchange Ratio, as of the date of such opinion,

    THE FULL TEXT OF THE WRITTEN OPINION OF RAYMOND JAMES & ASSOCIATES, INC.,
DATED OCTOBER 15, 1998, WHICH SETS FORTH ASSUMPTIONS MADE, MATTERS CONSIDERED
AND LIMITS ON THE SCOPE OF REVIEW UNDERTAKEN, IS ATTACHED AS APPENDIX C TO THIS
PROXY STATEMENT. DENTAL CARE ALLIANCE STOCKHOLDERS ARE URGED TO READ THIS
OPINION IN ITS ENTIRETY. RAYMOND JAMES & ASSOCIATES, INC.'S OPINION, WHICH IS
ADDRESSED TO THE DENTAL CARE ALLIANCE BOARD, IS DIRECTED ONLY TO THE FAIRNESS OF
THE DENTAL CARE ALLIANCE EXCHANGE RATIO 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 PROXY STATEMENT. THE SUMMARY OF THE OPINION OF RAYMOND JAMES &
ASSOCIATES, INC. SET FORTH IN THIS PROXY STATEMENT 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 Dental Care Alliance Exchange Ratio to Dental
Care Alliance stockholders from a financial point of view and were provided to
the Dental Care Alliance Board. 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 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's 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 or Dental Care Alliance management would
have been willing to agree to a different Dental Care Alliance 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, 1998 and August 14, 1998, and other publicly available financial
information of Dental Care Alliance; 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 Dental; reviewed

Alliance, including financial statements, financial projections, and other
financial and operating data concerning Dental Care Alliance; reviewed certain
non-public information prepared by the management of Gentle Dental, including

data concerning Gentle Dental; discussed the past and current operations and
financial condition and the prospects of
 
                                       40
<PAGE>
Dental Care Alliance and Gentle Dental with senior executives of Dental Care
Alliance and Gentle Dental, respectively; reviewed publicly available financial
and stock market data with respect 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; compared the financial terms of the Mergers with the
financial terms of certain other mergers which are generally comparable to the
Mergers; reviewed a draft of the Agreement; and conducted other financial
analyses, studies, and investigations, and considered other information as
Raymond James & Associates, Inc. deemed necessary or appropriate.
 
    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
discussed with Raymond James & Associates, Inc. became inaccurate or was
required to be updated during the period of the review. In addition, Raymond
James & Associates, Inc. has assumed, with the consent of Dental Care Alliance
and Gentle Dental, that the Mergers will be accounted for as
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 the Mergers.
 
    HISTORICAL STOCK PERFORMANCE ANALYSIS.  Raymond James & Associates, Inc.
described for the Dental Care Alliance Board the relative range of implied
Dental Care Alliance 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. These implied Dental Care
Alliance Exchange Ratios were calculated by dividing the price per share for
Dental Care Alliance Common Stock by the price per share for Gentle Dental
Common Stock. During the time period used for the analysis, the implied Dental
Care Alliance Exchange Ratio 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 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
 
                                       41
<PAGE>
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 earnings before interest, taxes, depreciation
and amortization ("EBITDA"); target company enterprise value to target company
earnings before interest and taxes ("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 Dental Care Alliance Merger. 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 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 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, and 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.
 
                                       42
<PAGE>
    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 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 Dental Care Alliance Exchange Ratio of 1.67 in the
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 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
 
                                       43
<PAGE>
Care Alliance Board 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 Mergers (the "Synergies") 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 Synergies estimate in its
analysis and has not undertaken any independent verification of the Synergies
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 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 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 in the
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.
 
    OPINION OF RAYMOND JAMES & ASSOCIATES, INC.  At the October 13 and 15, 1998
meetings of the Dental Care Alliance Board, Raymond James & Associates, Inc.
gave its oral and written opinion that, as of such date and based upon and

Common Stock might trade subsequent to the Mergers.

EXCHANGE OF STOCK; TREATMENT OF OPTIONS AND OTHER RIGHTS TO ACQUIRE GENTLE
  DENTAL CAPITAL STOCK
 
    THE GENTLE DENTAL EXCHANGE.  At the Effective Time, each share of Gentle

dissenters' rights shall have been properly
 
                                       45
<PAGE>
demanded in accordance with Chapter 23B.13 of the Washington Law ("Dissenting
Shares") will be exchangeable into one share of Wisdom Holdings Common Stock.
 
    Notwithstanding any other provision of the Agreement, Dissenting Shares will
not be exchanged for Gentle Dental Common Stock. Holders of Dissenting Shares
("Dissenting Shareholders") 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 Law, provided that if any Dissenting Shareholder subsequently
delivers a written withdrawal of such holders' demand for appraisal of such
shares, or if any holder fails to establish such holders' entitlement to
dissenters' rights as provided in Chapter 23B.13 of the Washington Law, 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 Holdings Common Stock on the terms provided in the
Agreement. See "Dissenters' Appraisal Rights."
 
    Each stock option or other right to acquire Gentle Dental Common Stock
granted under Gentle Dental's option plans (the "Gentle Dental Option Plans") or
other such rights that are outstanding and unexercised immediately prior to the
Effective Time 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, 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 Gentle Dental Exchange Ratio.
 
    Each share of Gentle Dental Series A preferred stock issued and outstanding
prior to the Effective Time ("Gentle Dental Series A Preferred") shall be
converted into and exchanged for one share of Wisdom Holdings Series A preferred
stock ("Wisdom Holdings Series A Preferred"). The terms of the Wisdom Holdings
Series A Preferred will be substantially the same as the terms of the Gentle
Dental Series A Preferred. Each share of Gentle Dental Series B preferred stock
issued and outstanding prior to the Effective Time ("Gentle Dental Series B
Preferred") shall be converted into and exchanged for one share of Wisdom
Holdings Series B preferred stock ("Wisdom Holdings Series B Preferred"). The
terms of the Wisdom Holdings Series B Preferred will be substantially the same
as the terms of the Gentle Dental Series B Preferred. Each share of Gentle
Dental Series C preferred stock issued and outstanding prior to the Effective
Time ("Gentle Dental Series C Preferred") shall be converted into and exchanged
for one share of Wisdom Holdings Series C preferred stock ("Wisdom Holdings
Series C Preferred"). The terms of the Wisdom Holdings Series C Preferred will
be substantially the same as the terms of the Gentle Dental Series C Preferred.
Each share of Gentle Dental Series D preferred stock issued and outstanding
prior to the Effective Time ("Gentle Dental Series D Preferred") shall be
converted into and exchanged for one share of Wisdom Holdings Series D preferred
stock ("Wisdom Holdings Series D Preferred"). The terms of the Wisdom Holdings
Series D Preferred will be substantially the same as the terms of the Gentle
Dental Series D Preferred. 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, each share of
Dental Care Alliance common stock outstanding will be converted into and
exchanged for the right to receive a number of
 
                                       46
<PAGE>
shares of Wisdom Holdings Common Stock equal to the Exchange Ratio (1.67),
subject to customary antidilution adjustments as provided in the 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) 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.
 
    Each stock option and warrant to acquire Dental Care Alliance common stock
granted under Dental Care Alliance's option plans (the "Dental Care Alliance
Option Plans") or otherwise, outstanding and unexercised immediately prior to
the Effective Time 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 Dental Care Alliance
Option Plans. The Dental Care Alliance Option Plans will be assumed by Wisdom
Holdings. In each case, (i) 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
(ii) 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, 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, 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 Dental Care Alliance Exchange
Ratio.
 
EXCHANGE OF CERTIFICATES; FRACTIONAL SHARES
 
    At or prior to the Effective Time, Wisdom Holdings will deposit, or cause to
be deposited, with               , or another bank or trust company reasonably
acceptable to each of Gentle Dental and Dental Care Alliance (the "Exchange
Agent"), for the benefit of the holders of certificates of Gentle Dental Common
Stock, certificates representing the shares of Wisdom Holdings Capital Stock
(the "Exchange Fund") to be issued pursuant to the Agreement in exchange for
outstanding shares of Gentle Dental Capital Stock.
 
    As soon as is practicable after the Effective Time, a form of transmittal
letter will be mailed by the Exchange Agent to the 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.

    NEITHER GENTLE DENTAL CAPITAL STOCK NOR DENTAL CARE ALLIANCE COMMON STOCK
SHOULD BE RETURNED WITH THE ENCLOSED PROXY OR FORWARDED TO THE EXCHANGE AGENT
UNLESS AND UNTIL THE GENTLE DENTAL SHAREHOLDER OR THE DENTAL CARE ALLIANCE
STOCKHOLDER RECEIVES A FORM OF TRANSMITTAL LETTER FOLLOWING THE EFFECTIVE TIME.
 
    Until the certificates representing Gentle Dental Capital Stock and Dental
Care Alliance Common Stock, as the case may be, are surrendered for exchange
after the Effective Time, dividends or other distributions declared after the
Effective Time 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, 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. 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. 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 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 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"). The
Closing Date will occur on a date to be specified by the parties, which date
shall be 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 Agreement. Gentle Dental and
Dental Care Alliance each anticipate that the Mergers will be consummated during
the fiscal quarter ending December 31, 1998. However, the consummation of the
Mergers could be delayed if there is a delay in obtaining the Requisite
Regulatory Approvals (as defined therein). 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 Agreement may
be terminated by either Gentle Dental or Dental Care Alliance,
 
                                       48

unless the failure to effect the Mergers by such date is due to the failure of
the party seeking to terminate the 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."

                                       52

    Agreement shall be true and correct as of the date of the Agreement and
    (except to the extent such representations and warranties speak as of an

    provided that for purposes of this condition, such representations and
    warranties will be deemed to be true and correct unless the failure or

or waived by the party permitted to do so. If the Mergers are not effected on or
before March 31, 1999, the Agreement may be terminated by either Gentle Dental
or Dental Care Alliance, unless the failure to effect the Mergers by such date

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 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 Joint Proxy Statement-Prospectus 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
 
                                       53
<PAGE>
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 Code, 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 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, 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.
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:
 
        (i) 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 Holding Acquisition Corp. I,
    Dental Care Alliance and Wisdom Holding Acquisition Corp. II will each be a
    party to the reorganization within the meaning of Section 368(b) of the Code
    or (B) transfers to a controlled corporation qualifying under Section 351 of
    the Code, and
 
        (ii) 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 in exchange for shares of Gentle Dental Common Stock or Gentle
    Dental Series D Preferred 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 (the "IRS") or the courts, and the
parties do not intend to request a ruling from the IRS with respect to the
Mergers. Accordingly, there can be no assurance that the IRS 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 IRS,
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
 
                                       54
<PAGE>
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.
 
    The adjusted tax basis of the Wisdom Holdings Common Stock or Series D
Preferred 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 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 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 Preferred 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. 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 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 may be subject to backup withholding at a rate of 31% with respect to
dividends, unless the stockholder (i) is a corporation or comes within certain
other exempt categories and, when required, demonstrates that fact or (ii)
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
IRS. A Wisdom Holdings stockholder who does not 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 IRS. The information reporting rules will apply to dividends on Wisdom
Common Stock and Wisdom Holdings Series D Preferred unless the stockholder is a
corporation or is otherwise exempt from those rules.
 
ACCOUNTING TREATMENT
 
    The parties anticipate that the Mergers will be accounted for as "pooling of
interests" transactions under GAAP. 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 for (in the case of Dental Care Alliance stockholders), 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 Mergers will be accounted for as a "pooling
of interests." See "--Conditions to Consummation of the Mergers."

    The unaudited pro forma financial information contained in this Joint Proxy
Statement-Prospectus has been prepared assuming that the transaction will
qualify as a "pooling of interests" accounting method to account for the
Mergers. See "Summary--Unaudited Comparative Per Share Data" and "Unaudited Pro
Forma Condensed Combined Financial Information."
 
TERMINATION OF THE MERGER AGREEMENT
 
    The 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:
 
        (i) 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;
 
        (ii) by either the Gentle Dental Board or Dental Care Alliance Board
    (provided that the terminating party is not then in material breach of any
    representation, warranty, covenant or other agreement contained in the
    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 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;
 
       (iii) by either the Gentle Dental Board or Dental Care Alliance Board 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;
 
        (iv) by either the Gentle Dental Board or Dental Care Alliance Board 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 Agreement;
 
        (v) 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
 
        (vi) by written notice of Gentle Dental or Dental Care Alliance if
    either receives an Acquisition Proposal, as defined in the Agreement, and
    outside counsel advises that to proceed with the Mergers would violate
    either the Gentle Dental Board's or the Dental Care Alliance Board's
    fiduciary duty 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
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 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 AGREEMENT
 
    WAIVER AND AMENDMENT.  At any time prior to the Effective Time, any
provision of the Agreement may be (i) waived by the party benefited by the
provision or (ii) amended or modified by an agreement in writing between the
parties to the Agreement except, following the meetings of the respective
stockholders of Gentle Dental and Dental Care Alliance, the Agreement may not be
amended if such amendment would violate either Washington Law or Delaware 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 (i) 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 in accordance with the
policies of Wisdom Holdings with respect to such stock option plan, and (ii)
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 Gentle Dental Option Plans and in Dental Care Alliance
Option Plans a notice setting forth such participant's rights pursuant thereto
and the grants pursuant to the Gentle Dental Option Plans and the Dental Care
Alliance 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 the Gentle Dental Option Plan and the Dental Care Alliance
Option Plan to ensure that Gentle Dental stock options and Dental Care Alliance
stock options which 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 Agreement. As soon as practicable
after the Effective Time, Wisdom Holdings will file a registration statement
with respect to the shares of Gentle Dental Common Stock or Dental Care Alliance
Common Stock subject to such options (if any) 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.
 
                                       57
<PAGE>
STOCK EXCHANGE LISTING
 
    Wisdom Holdings has agreed to cause the shares of Wisdom Holdings Common
Stock and Wisdom Holdings Preferred 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 and
Wisdom Holdings Preferred Stock be authorized for listing on Nasdaq, subject to
official notice of issuance.
 
EXPENSES
 
    The 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 MERGER
 
    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. 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 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. Fiore,
Van Eerden, Tse, 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 agreement with Wisdom Holdings for Dr. Matzkin
will have certain modifications from the previous employment agreement with
Dental Care Alliance. 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. 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.
 
    STOCK-BASED RIGHTS.  The Agreement provides that, at the Effective Time,
each outstanding stock option to acquire shares of Gentle Dental Common Stock
granted under the Gentle Dental Stock Plans or Dental Care Alliance Common Stock
under Dental Care Alliance Stock 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 Wisdom Holdings Common
Stock. Any existing plans 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 Common Stock held by them
following the Effective Time and all 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
 
                                       58
<PAGE>
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 Agreement 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. A 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 they will vote or direct the vote of all such
outstanding shares of Dental Care Alliance Common Stock over which they have
voting control in favor of the approval and adoption of the 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 112,755 of Mr Fiore's shares and 16,691 of Mr.
Sadler's shares are now subject to the repurchase option. 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.
 
RESTRICTIONS ON RESALES BY AFFILIATES
 
    The issuance of shares of Wisdom Holdings Capital Stock to holders of Gentle
Dental Capital Stock and the issuance of shares of Wisdom Holdings Common Stock
to holders of Dental Care Alliance Common Stock in the Mergers have been
registered under the Securities Act of 1933, as amended (the "Securities Act").
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, 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 will, under existing law, require either (i) the
further registration under the Securities Act of the shares of Gentle Dental or
Dental Care Alliance Capital Stock to be transferred, (ii) compliance with Rule
145 promulgated under the Securities Act (permitting limited sales under certain
circumstances) or (iii) 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 the Gentle Dental Common 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 the transfer agent with respect to the Wisdom
Holdings stock to be received by persons subject to the restrictions described
above, and the certificates for such stock will be appropriately legended.
 
    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. Commission
guidelines indicate 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.
 
                                       59
<PAGE>
    Each of Gentle Dental and Dental Care Alliance has agreed in the 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 Merger 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 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 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 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 the record date, each have agreed, as a condition to Gentle Dental
and Dental Care Alliance entering into the 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 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 Merger (except for certain provisions which will survive the
completion of the Mergers) and the date on which the 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 shareholders. 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
or Dental Care Alliance, as the case may be, when they decided to approve
Mergers. In addition, such stockholders/directors will continue to be free to
exercise their fiduciary duties as Gentle Dental and Dental Care Alliance
directors with respect to any decisions they may take in connection with the
Mergers or otherwise. In addition, such stockholders are not prohibited from
voting their shares in favor of other acquisition proposals, should any such
proposals be brought to such stockholders for a vote.

                  OPERATIONS AND MANAGEMENT OF WISDOM HOLDINGS
                                AFTER THE MERGER
 
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. 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
Joint Proxy Statement/Prospectus.
 
RESULTS OF OPERATIONS
 
    To provide a more meaningful comparison, the following discussion generally
compares (i) expenses to (ii) the total of dental practice net patient service
revenue of consolidated and unconsolidated affiliated dental practices. 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 (the "EITF") of the Financial Accounting Standards Board. In those
instances where such consolidation requirements are not met, Gentle Dental (i)
reports net management fees revenue and (ii) 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 EITF consolidation requirements 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 EITF consolidation requirements. The remaining dental practice, acquired
effective April 1, 1997, that had not met the EITF consolidation requirements.
 
YEAR ENDED DECEMBER 31, 1997 STATEMENT OF OPERATIONS COMPARED TO YEAR ENDED
  DECEMBER 31, 1996 STATEMENT OF OPERATIONS
 
    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 directly attributable to five affiliations completed in 1996 and
six affiliations completed in 1997, representing 23 clinical locations. These
affiliations have management agreements that meet the EITF 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.
 
    If all affiliated dental practices met the EITF consolidation requirements,
total dental practice net patient revenue reported would have been $25.1 million
for the year ended December 31, 1996 and $56.0 million for the year ended
December 31, 1997, representing a 121% increase.
 
                                       67
<PAGE>
    CLINICAL SALARIES AND BENEFITS.  Clinical salaries and benefits costs
include all patient service provider staff compensation (including dentists,
hygienists and assistants) and related payroll costs at the consolidated
affiliated dental practices. Clinical salaries and benefits costs 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 costs as a
percentage of dental practice net patient revenue for the years ended December
31, 1996 and 1997 were 40.3% and 47.4%, respectively. The addition of affiliated
dental practices with Gentle Dental in 1996 and 1997 contributed to such
increase.
 
    PRACTICE NONCLINICAL SALARIES AND BENEFITS.  Practice nonclinical salaries
and benefits costs include all staff compensation (other than dentists,
hygienists and dental assistants) and related payroll costs at the dental
facilities. Total nonclinical salary costs increased 91.1% 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 attributable to the addition of costs from
affiliations completed during 1996 and 1997. If all Gentle Dental revenue had
been reported at the dental practice net patient revenue level, practice
clinical salaries and benefits costs as a percentage of total revenue for the
years ended December 31, 1996 and 1997 would have been 17.0% and 14.6%,
respectively.
 
    DENTAL SUPPLIES AND LAB COSTS.  Total 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. If all Gentle Dental revenue had
been recorded at the dental group net patient service revenue level, dental
supplies and lab costs as a percentage of total revenue for the year ended
December 31, 1996 and 1997 would have been 11.3% and 11.2%, respectively.
 
    PRACTICE OCCUPANCY.  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 in occupancy expenses was primarily
attributable to the addition of costs from affiliations completed during 1996
and 1997. If all Gentle Dental revenue had been recorded at the dental practice
net patient service revenue level, practice occupancy cost as a percentage of
total revenue for the years ended December 31, 1996 and 1997 would have been
6.2% and 6.3%, respectively. The slight increase in comparable costs was due to
higher rent, as a percentage of revenue, at new affiliated dental practices.
 
    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
clinical office level. 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. If all Gentle Dental revenue had
been recorded at the dental group net patient service revenue level, practice
selling, general and administrative expenses as a percentage of total revenue
for the years ended December 31, 1996 and 1997 would have been 7.2% and 8.8%,
respectively. The addition of affiliated dental practices in 1996 and 1997
contributed to such increase.
 
    CORPORATE SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Total 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. If all Gentle Dental revenue had been recorded at the dental practice
net patient service revenue level, corporate selling, general and administrative
expenses as a percentage of total revenue for the years ended December 31, 1996
and 1997 would have been 11.9% and 10.2%, respectively. 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.  Total depreciation and amortization expense
for the years ended December 31, 1996 and 1997 were $1.0 million and $1.8
million, respectively. This increase was primarily due to the addition of
affiliated dental practices in 1996 and 1997.
 
                                       68
<PAGE>
    INTEREST EXPENSE.  Total interest expense decreased 12.9% 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 partly
offset by additional debt incurred to complete additional dental practice
affiliations in 1997.
 
    PROVISION (BENEFIT) FOR INCOME TAXES.  For the years ended December 31, 1996
and 1997, Gentle Dental recognized a tax benefit resulting from its taxable
losses for those years. The effective tax rate for the tax benefit was lower
than the statutory rate due to the tax-free merger structure for certain dental
practice affiliations. As a result, the amortization of certain intangible
assets reduced earnings, but was not deductible for tax purposes.
 
SIX MONTHS ENDED JUNE 30, 1997 STATEMENT OF OPERATIONS COMPARED TO SIX MONTHS
  ENDED JUNE 30, 1998 STATEMENT OF OPERATIONS
 
    DENTAL PRACTICE NET PATIENT SERVICE REVENUE.  If all the affiliated dental
practices were accounted for on a consolidated basis, total dental practice net
patient revenue reported would have been $23.6 million for the six months ended
June 30, 1997 and $40.3 million for the six months ended June 30, 1998,
representing a 70.7% increase. This increase is directly attributed to nine
affiliations completed during the year ended December 31, 1997 and four
affiliations completed during the six months ended June 30, 1998, representing
27 clinical locations.
 
    CLINICAL SALARIES AND BENEFITS.  If all affiliated dental practices were
accounted for on a consolidated basis, clinical salaries and benefits costs
would have been $11.3 million for the six months ended June 30, 1997 and $18.5
million for the six months ended June 30, 1998. Practice clinical salaries and
benefits costs as a percentage of dental practice net patient revenue for the
six months ended June 30, 1997 and 1998 were 47.9% and 46.0%, respectively. This
decrease was the result of the new management service agreements entered into as
of January 1, 1998 with certain affiliations located in Oregon and Washington.
Also, the addition of affiliated dental practices with Gentle Dental in 1997 and
the six months ended June 30, 1998 contributed to such decrease.
 
    PRACTICE NONCLINICAL SALARIES AND BENEFITS.  Total nonclinical salary costs
increased 70.9% from $3.4 million for the six months ended June 30, 1997 to $5.9
million for the six months ended June 30, 1998. This increase was primarily
attributable to the addition of costs from affiliations completed during 1997
and the six months ended June 30, 1998. If all Gentle Dental revenue had been
reported at the dental practice net patient revenue level, practice nonclinical
salaries and benefits costs as a percentage of total revenue for the six months
ended June 30, 1997 and 1998 would have been 14.6% for both periods.
 
    DENTAL SUPPLIES AND LAB COSTS.  Total dental supplies and lab costs
increased 69.2% from $2.7 million for the six months ended June 30, 1997 to $4.5
million for the six months ended June 30, 1998. The addition of affiliated
dental practices in 1997 and 1998 contributed to such increase. If all Gentle
Dental revenue had been recorded at the dental group net patient service revenue
level, dental supplies and lab costs as a percentage of total revenue for the
six months ended June 30, 1997 and 1998 would have been 11.4% and 11.3%,
respectively.
 
    PRACTICE OCCUPANCY.  Practice occupancy expenses increased 52.6% from $1.5
million for the six months ended June 30, 1997 to $2.3 million for the six
months ended June 30, 1998. This increase was primarily attributable to the
addition of costs from affiliations completed during 1997 and the six months
ended June 30, 1998. If all Gentle Dental revenue had been recorded at the
dental practice net patient service revenue level, practice occupancy cost as a
percentage of total revenue for the six months ended June 30, 1997 and 1998
would have been 6.3% and 5.6%, respectively. The expense mix of affiliated
dental practices affiliating with Gentle Dental in 1997 and 1998 contributed to
the decrease in this percentage.
 
                                       69
<PAGE>
    PRACTICE SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Practice selling,
general and administrative expenses increased 87.7% from $2.0 million for the
six months ended June 30, 1997 to $3.8 million for the six months ended June 30,
1998. If all Gentle Dental revenue had been recorded at the dental group net
patient service revenue level, practice selling, general and administrative
expenses as a percentage of total revenue for the six months ended June 30, 1997
and 1998 would have been 11.5% and 9.7%, respectively. The expense mix of
affiliated dental practices affiliating with Gentle Dental in 1997 and 1998
contributed to such decrease.
 
    CORPORATE SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Total corporate
selling, general and administrative expenses increased 24.2% from $2.2 million
for the six months ended June 30, 1997 to $2.8 million for the six months ended
June 30, 1998. If all Gentle Dental revenue had been recorded at the dental
practice net patient service revenue level, corporate selling, general and
administrative expenses as a percentage of total revenue for the six months
ended June 30, 1997 and 1998 would have been 9.4% and 6.9%, respectively. The
increase in total expense is a result of Gentle Dental implementing
infrastructure required to accommodate expected future growth.
 
    DEPRECIATION AND AMORTIZATION.  Total depreciation and amortization expense
for the six months ended June 30, 1997 and 1998 was $816,000 and $1.6 million,
respectively. The increase was primarily due to the addition of affiliated
dental practices in 1997 and 1998.
 
    INTEREST EXPENSE.  Total interest expense increased from $193,000 for the
six months ended June 30, 1997 to $1.0 million for the six months ended June 30,
1998. This increase in interest expense was due to additional debt incurred to
complete certain dental practice affiliations in 1997 and 1998.
 
    INCOME TAX (BENEFIT) EXPENSE.  For the six months ended June 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 six months
ended June 30, 1998, Gentle Dental recognized a tax benefit resulting from its
taxable loss as management believe that Gentle Dental would be able to utilize
available tax loss carryforwards. The effective tax rate for the tax benefit was
lower than the statutory rate due to Gentle Dental's tax-free merger structure
for certain dental practice affiliations, resulting in amortization of certain
intangible assets which are not deductible for tax purposes.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    At June 30, 1998, Gentle Dental's cash and cash equivalents were $16.2
million and working capital was $10.8 million. The increase in cash equivalents
and working capital at December 31, 1997 was the result of a $45 million private
placement of debt and Gentle Dental Preferred Stock during the six months ended
June 30, 1998.
 
    Net cash used in operations was $842,000 and $1.8 million for the six-month
periods ended June 30, 1997 and 1998, respectively. Net cash used in investing
activities, principally dental practice affiliations, was $3.1 million and $15.5
million for the six-month periods ending June 30, 1997 and 1998, respectively.
Net cash provided from financing activities was $2.5 million and $33.3 million
for the six-month periods ended June 30, 1997 and 1998, respectively.
 
    On January 1, 1998, Gentle Dental and certain affiliations in Washington and
Oregon entered into asset purchase and management service agreements. Under the
terms of such management service 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 an aggregate of $575,000 in cash in
18 monthly installments. The new management service agreements meet the EITF
consolidation requirements.
 
                                       70
<PAGE>
    During the six months ended June 30, 1998, Gentle Dental completed six
dental practice affiliation transactions. These affiliations represent the
purchased assets of 21 clinical locations for $13.8 million in cash, 378,987
shares of Gentle Dental Common Stock valued at $2.8 million, liabilities
incurred or assumed of $11.2 million (of which $6.5 million was paid in July
1998) and additional future consideration based upon financial performance
targets. Such affiliations were accounted for using the purchase method of
accounting.
 
    On July 28, 1998, Gentle Dental completed the affiliation of a dental
practice located in Northern California, representing one clinical office
location. The purchase price for this affiliation totaled $1.5 million in cash.
This affiliation was accounted for using the purchase method of accounting.
 
    On July 31, 1998, Gentle Dental completed the acquisition of all the stock
of Dedicated Dental Systems, Inc., a Bakersfield, California company which owns
and operates eleven staff model dental offices pursuant to a license granted
under the Knox-Keene Act. Also, pursuant to the terms of three asset purchase
agreements, Gentle Dental completed the acquisition of the non-professional
assets of related dental practices operating at four locations in southern
California. The aggregate purchase price for these affiliations consisted of
$16.4 million in cash and 705,101 shares of Gentle Dental Common Stock valued at
$5.8 million.
 
RECENT DEVELOPMENTS
 
    On October 30, 1998, Gentle Dental acquired all of the issued and
outstanding shares of stock of Capitol Dental Care, Inc., an Oregon corporation,
and purchased substantially all 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 $800,000.00, 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, $1.7
million pursuant to a promissory note payable in equal quarterly installments of
principal and interest over a three year term and bearing interest at the annual
rate of 8%. Dental Management of Oregon, P.C., can earn additional cash
consideration if its earnings increase over a two-year period pursuant to a
formula described in the acquisition agreements.
    Capitol Dental Care, Inc. provides capitated dental services under the
Oregon Health Plan pursuant to 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 June
30, 1998, Gentle Dental had accrued $1.4 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
 
                                       71

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 during 1998.
 
    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
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 at a rate of one share of Gentle Dental
Series B Preferred 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 and Gentle Dental Series C
Preferred, 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, all of which

    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 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.
 
    YEAR 2000 COMPLIANCE.  Gentle Dental has purchased software that runs on its
computer network which it believes is Year 2000 compliant. Gentle Dental is
currently evaluating its key suppliers to determine whether they are Year 2000
compliant and to determine the impact, if any, on the financial position and
results of operations. Currently, the Year 2000 issues are not expected to
materially impact the financial position and results of operations of Gentle
Dental.
 
CERTAIN TRANSACTIONS REGARDING GENTLE DENTAL
 
    The outstanding capital stock of certain professional corporations located
in Oregon and Washington (the "Oregon and Washington Professional Corporations")
is owned in whole or in part by Dany Y. Tse and Gerald R. Aaron. Gentle Dental
is a party to certain management agreements with each of the Oregon and
Washington 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 the
Oregon and Washington 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: (i)
approximately $1.8 million in cash offset by approximately $1.8 million of
Gentle Dental receivables due from such Oregon and Washington Professional
Corporations; (ii) 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 (iii) 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 (the "Modification"). 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 common stock at an aggregate exercise
price of $150,000. On the same date,
 
                                       73
<PAGE>
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 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 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 common stock for $88,868. The purchase price was paid in part in the form of
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 converted into 395,541 shares of 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. 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 these employment
agreements, the annual base salaries of Messrs. Fiore, Tse and Van Eerden are
$250,000, $243,000, 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
 
                                       74
<PAGE>
cause. The employment agreement for Dr. Tse provides for an initial term through
June 30, 2003, subject to a renewal term through June 30, 2008, and further
provides 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.
 
    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." If Dr. Tse voluntarily terminates
his employment for "good reason" prior to July 1, 2001, Dr. Tse will be entitled
to enter into a 12-month consulting agreement at his base salary; upon
termination of the 12-month consulting agreement, Dr. Tse will be entitled to
severance payments for 24 months based on his base salary. If Dr. Tse
voluntarily terminates his employment for "good reason" after July 1, 2001, Dr.
Tse will be entitled to enter into a 12-month consulting agreement at his base
salary; upon termination of the 12-month consulting agreement, Dr. Tse will be
entitled to severance payments for 12 months based on his base salary. If Gentle
Dental terminates Dr. Tse's employment without "cause" after April 30, 2002, Dr.
Tse will be entitled to receive severance payments based on his base salary for
the period through June 30, 2003. For purposes of each of the employment
agreements, "cause" means (i) 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; (ii) any breach by employee of certain sections of the
employment agreement relating to covenants of non-solicitation, non-competition
and confidentiality; (iii) 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 (iv) 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. Employee shall
not be considered to have been terminated for "cause" if terminated by Gentle
Dental solely (a) as a result of employee's bad judgment or negligence, (b)
because of any act or omission believed by employee in good faith to have been
in or not opposed to the best interests of 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, (c) 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 (d)
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 (i) 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, (ii) a demotion in position from
the employee's positions with Gentle Dental as of the date the employment
agreement was executed, or (iii) 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.
 
    The above-described transactions with related parties were on terms the
Gentle Dental Board 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. The policy provides that any transaction between Gentle
Dental and (i) an officer, director, or principal shareholder of Gentle Dental
or (ii) 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 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.

<PAGE>
    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, and will entitle Mr. Fiore to severance
payments based on his base salary for a period 36 months, if he is terminated
during the initial year of the agreement's term, and for a period 24 months if
he is terminated at any time during the remainder of its term.

                     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
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 ("Managed Dental
Centers") operated by 38 professional corporations and associations ("PAs").
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 PAs 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 PAs are responsible for compliance with state and local
regulations of the practice of dentistry and with licensing and certification
requirements, and each PA is responsible for acquiring and maintaining
professional liability insurance.
 
    Almost all of its management agreements provide that Dental Care Alliance
(i) 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, (ii) provide, maintain and repair all
offices, equipment and furnishings, (iii) employ all non-professional personnel
necessary for the operation of the managed dental centers, (iv) provide payroll
services, (v) implement standard business systems and procedures and provide or
facilitate systems and efficiencies training, (vi) order all general business
inventory and supplies required by the managed dental centers and handle
accounts payable, (vii) establish and maintain information systems and provide
accounting and bookkeeping services, (viii) monitor compliance with rules and
regulations applicable to the managed dental centers' business, (ix) provide
marketing assistance and (x) provide assistance in billing and collections, all
to the extent permitted by law.
 
    These management agreements also provide that the PAs are responsible for,
among other things, (i) employing and supervising all dentists and dental
hygienists, (ii) complying with all laws, rules and regulations relating to
dentists and dental hygienists, (iii) participating in quality
assurance/utilization
 
                                       82
<PAGE>
review programs, (iv) maintaining proper dental patient records, (v) 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
(vi) any other requirements to carry out the practice of dentistry.
 
    As compensation for its management services under the Standard Management
Agreements (as herein defined), the PAs pay Dental Care Alliance a management
fee equal to 67%-74% of the net collected revenues earned by the PA. Dental Care
Alliance pays all of the operating and nonoperating expenses incurred by the PAs
except for (i) salaries and benefits to the dentists and dental hygienists, (ii)
licensing fees paid to Dental Care Alliance, (iii) debt and asset carrying costs
related to the acquisition of the dental practice and (iv) any other direct cost
to the PA 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 (each, a
"Dental Director"). The primary purpose of the 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 PAs in their region with hiring, training
and supervision of dental professionals. Dental Care Alliance believes that
close relationships among the Dental Directors, the PAs 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 PA
    to a percentage of net patient revenues from each PA. 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 PA's financial statements. See "Dental Care Alliance Management's
    Discussion and Analysis of Financial Condition and Results of Operations."

DENTAL CARE ALLIANCE'S MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
  CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    With respect to management services it provides to dental practices, Dental
Care Alliance enters into management agreements with PAs 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 management
agreements
 
                                       85
<PAGE>
to manage five practices in Michigan and 12 in Florida. As of June 30, 1998,
Dental Care Alliance provided management and licensing services to 49 managed
dental centers, 32 of which are located in Florida, nine of which are located in
Michigan and eight of which are located in Georgia. In addition, Dental Care
Alliance provides only licensing services to three dental centers in Florida as
of June 30, 1998.
 
    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, as
defined in the management agreements, 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 ("Net Collected Revenues") and
Dental Care Alliance would assume responsibility for the payment of the
non-professional expenses of the Managed Dental Centers (the "Standard
Management Agreements"). 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 Standard Management Agreements, except that management fees
have ranged from 67% to 74% of 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 PA provides for a management fee based
upon net profits or net patient revenue. In the "net profits" type of management
agreement, both the PA 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 PA located in Port Charlotte, Florida
contributed approximately 18% and 9% to Dental Care Alliance's revenues in 1996
and 1997. The Flint Management Agreement has a term of 25 years and provides for
a management fee equal to 74% of the Net Collected Revenues earned by the
associated PA. The Port Charlotte Management Agreement expires in 2003 and
provides for a management fee of 55% of the net profits of the associated PA. In
addition, the Port Charlotte management agreement provides that the PA 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 PA has indicated that it may
seek to terminate the agreement, but has not definitively notified Dental Care
Alliance that it will do so. Dental Care Alliance earned fees of $121,900 for
the year ended December 31, 1997 and $83,500 for the six months ended June 30,
1998.
 
    All patient revenues are billed to patients and providers under the
authority and identification numbers of the individual PAs. Patient revenues and
receivables are recorded on the accounts of the PAs. Funds are dispersed
initially to pay all the professional costs of the PAs. Thereafter, funds are
disbursed to Dental Care Alliance under the terms of the management agreements.
Any remaining funds are retained by the PA. If funds are insufficient to pay
Dental Care Alliance under the terms of the relevant
 
                                       86
<PAGE>
management agreement, a payable from the PA 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
PA 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 PA or
has assisted the PA 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 PAs acquire the dental assets of such
Managed Dental Centers. In addition, due to changing market conditions, Dental
Care Alliance has begun compensating PAs for the execution of management
agreements.
 
    Dental Care Alliance from time to time has made loans to newly formed PAs
with which it has entered into management agreements to purchase the dental
assets of the related dental practices. In return the PAs execute promissory
notes to Dental Care Alliance in the amount of such loans. At June 30, 1998, the
total outstanding balance of such loans was $793,444. 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 PAs 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 PAs, although it is not obligated contractually or otherwise to make
such advances. The extension of loans and advances to the PAs 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 PAs
are guaranteed by the relevant PA 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 June 30, 1998, the total outstanding balance of such advances was
$1,361,517. There have been no revisions to the terms of any such loans or
advances. The PAs are current in the payment of their loans or advances and
Dental Care Alliance believes that the financial condition of the PAs 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 PA and the estimated fair market value of the assets to be owned or
owned by such PA. 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 PAs' 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 PA 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 PAs. Dental Care
Alliance also analyzes any historical trends of the PAs relating to bad debts or
the inability of the PAs to generate collectible patient receivables. Dental
Care Alliance assesses the guaranty of its PA 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 PA owner in the
business community and the length and quality of the PAs' relationship with
Dental Care Alliance are examined by Dental Care Alliance to assess the PA
owners as guarantors of
 
                                       87
<PAGE>
the loans and advances. Dental Care Alliance may modify the terms of management
agreements prospectively if the PA does not perform at a level sufficient to
repay the advances.
 
    None of the PA owners are officers, directors or employees of Dental Care
Alliance. Dr. Dennis A. Corona, the owner of PAs operating a majority of the
Managed Dental Centers, owns 1% of Dental Care Alliance Common Stock. In
addition, five Managed Dental Centers in Michigan are owned by PAs commonly
controlled by Dr. Ross Johnson.
 
    The PAs are primarily liable for repayment of the notes and advances to
Dental Care Alliance with the PA owners being secondarily liable for repayment
under the notes and advances. The PAs and PA 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 PAs or PA owners are insufficient to pay the
outstanding balances under the notes or advances upon any default.
 
    The PAs 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 PAs,
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 $62,000 as of June 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 PAs that have acquisition loans from Dental
Care Alliance and for most PAs with working capital advances provide that the
PAs 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 PA at a price equal to 60% of the annualized
gross revenues of such PA owner over the previous 24 months, minus any
liabilities, including outstanding indebtedness, if any, to Dental Care Alliance
of the PA at the date of purchase. In such event, Dental Care Alliance would
evaluate whether, at its option, to have another PA owner or other licensed
dentist assume control of the practice and continue to generate management fees
or to liquidate the assets of such PA.
 
    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 PAs, not Dental Care Alliance. Dental Care Alliance has recorded
goodwill and other intangible assets in cases where Dental Care Alliance has
paid a PA 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
 
                                       88
<PAGE>
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. ("Marketplace") pursuant to the merger
of Marketplace 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. All shares of Marketplace common stock were converted into the
right to receive, in the aggregate, eighty thousand (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 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 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 (i) $2,400,000 in cash; (ii) 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 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
 
SIX MONTHS ENDED JUNE 30, 1998 COMPARED TO THE SIX MONTHS ENDED JUNE 30, 1997
 
    MANAGEMENT FEES.  Management fees increased 377.5% from $2.5 million for the
six months ended June 30, 1997 to $11.8 million for the six months ended June
30, 1998. Revenues at existing practices grew nine percent to approximately $2.7
million, while the balance of the increase relates to the addition of 37 Managed
Dental Centers since January 1, 1997.
 
                                       89
<PAGE>
    CONSULTING AND LICENSING FEES.  Consulting and licensing fees increased
81.7% from $161,885 for the six months ended June 30, 1997 to $294,133 for the
six months ended June 30, 1998. The increase is attributable to the addition of
37 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 $2.0 million for the six months ended June 30, 1997 to $8.0 million for the
six months ended June 30, 1998. As a percentage of net patient revenue at
Managed Dental Centers, Managed Dental Center expenses decreased from 57% to
48%. The decrease is due to economies in purchasing of dental supplies and
laboratories (3%), reduced marketing expenditures (3%) in new affiliations with
established reputations and other general and administrative expenses (3%).
 
    SALARIES AND BENEFITS.  Salaries and benefits increased 110.8% from $373,016
for the six months ended June 30, 1997 to $786,414 for the six months ended June
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 37 Managed Dental Centers. As a percentage of net
patient revenue, salaries and benefits decreased from 11% to 5%.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
503.2% from $135,970 for the six months ended June 30, 1997 to $820,226 for the
six months ended June 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 37 Managed Dental Centers. As a
percentage of the net patient revenue, general and administrative increased from
4% to 5%.
 
    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization expense
increased 837.4% from $41,578 for the six months ended June 30, 1997 to $389,751
for the six months ended June 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 37 additional Managed
Dental Centers. As a percentage of net patient revenue, depreciation and
amortization increased from 1% to 2%.
    INTEREST INCOME, NET.  Interest income, net increased from $36,464 for the
six months ended June 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.

    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 PAs. 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
 
                                       90

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

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.

    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

    GENERAL AND ADMINISTRATIVE.  General and administrative expense increased
11.1% from $234,577 in 1995 to $260,558 in 1996. This increase was attributable

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 six months ended June 30, 1998 was $75,873, $270,121
$557,767 and $203,133, respectively. Net cash provided by operating activities
for the years ended December 31, 1995, 1996 and 1997 and the six months ended
June 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 six months ended June 30, 1998 was ($5,649), ($487,858),
($2.0 million) and ($11.8 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 six
months ended June 30, 1998, the investing activities included $8,667,063 related
primarily to the purchase of management agreements, $1,811,857 related to the
purchase of non-dental assets, $920,000 related to satisfaction of outstanding
obligations on acquisitions and affiliations and $450,000 related to an increase
in notes receivable to PAs.
 
    Cash (used in) provided by financing activities for the and the years ended
December 31, 1995, 1996 and 1997 and the six months ended June 30, 1998 was
($69,926), $1,428,803, $20,572,424 and $257,044, 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 PAs and
 
                                       93
<PAGE>
$167,945 in net repayment of debt. For the six months ended June 30, 1998 Dental
Care Alliance had $1,216,062 in net proceeds on long-term debt offset by
$878,096 in working capital advances to PAs.
 
    In August 1997, Dental Care Alliance entered into a revolving line of credit
(the "Credit Agreement") which provides for an aggregate of $1.2 million. Under
the terms of the Credit Agreement, Dental Care Alliance may use up to $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 June 30, 1998, Dental Care Alliance had no outstanding
balances against the Revolving Note.
 
    Dental Care Alliance previously has made loans to various PAs in connection
with the PAs' acquisition of assets of dental practices and has made working
capital advances to various PAs 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 PA 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 PAs 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.

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 Named
Executive Officers 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 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
 
                                       98
<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 (i) hold the offices of Co-Chairman, President and
Chief Dental Officer of Wisdom Holdings, (ii) 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, (iii) receive an automobile allowance of $1,000 per month and
(iv) be subject to covenants prohibiting disclosure of confidential information
of Wisdom Holdings and competition with, or solicitation of employees of, Wisdom
Holdings.
 
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 PA 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 ("EMS").
Certain Managed Dental Centers have entered into capitalized equipment leases
with EMS. Amounts paid by such Managed Dental Centers to EMS 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
 
                                       99
<PAGE>
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 (the "Dental Care Alliance
Stockholders' Agreement") among Dental Care Alliance and Dr. Matzkin, Mr. Smith,
Mr. Raucci, the SRM 1993 Children's Trust and Crescent International Holdings,
Inc. (collectively, the "Stockholders") initially entered into in connection
with the sale of Dental Care Alliance's Series A Preferred Stock in October
1996, each stockholder received (i) "piggyback" registration rights, (ii) a
right of first refusal with respect to a greater than 50% share transfer by a
stockholder prior to a Qualified Initial Public Offering (as defined in the
Dental Care Alliance Stockholders' Agreement), (iii) co-sale rights to
participate on a pro rata basis in certain resales of Dental Care Alliance
Common Stock by other Stockholders (other than in connection with a Qualified
Initial Public Offering) and (iv) participation rights with respect to certain
issuances of securities by Dental Care Alliance made prior to a Qualified
Initial Public Offering. In addition, Stockholders 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 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 (collectively, "Registrable
Shares"), (i) "piggyback" registration rights, and (ii) 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 "Dental Care Alliance's Management and Additional
Information--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.

be authorized, and the rights, preferences and privileges of such shares will be
substantially identical to the rights, preferences and privileges of the Gentle
Dental Series A Preferred, Gentle Dental Series B Preferred, Gentle Dental
Series C Preferred and Gentle Dental Series D Preferred, as the case may be. The
rights, preferences and privileges of the outstanding series of each Gentle
Dental Preferred Stock is described below. See "Description of Gentle Dental
Preferred Stock--Gentle Dental Preferred Stock."

                   DESCRIPTION OF GENTLE DENTAL CAPITAL STOCK
 
    The following description contains a summary of material features of the
capital stock of Gentle Dental but does not purport to be complete and is
subject in all respects to the applicable provisions of the Washington Business
Corporation Act ("Washington Law"), and is qualified in its entirety by
reference to the Gentle Dental's Restated Articles of Incorporation, as amended
(the "Gentle Dental Articles").
 
GENTLE DENTAL COMMON STOCK
 
    Each holder of Gentle Dental Common Stock is entitled to one vote for each
share held on all matters voted upon by shareholders. Shareholders are not
permitted to cumulate their votes for the election of directors. Because Gentle
Dental's Board of Directors is classified into three classes, shareholders elect
only the members of the Board of Directors whose class term is expiring at the
annual meeting and any members of the Board of Directors appointed to one of the
other classes during the term of such other class.
 
    In the event of the liquidation, dissolution or distribution of assets of
Gentle Dental, holders of Gentle Dental Common Stock will be entitled to share
ratably in any remaining assets of Gentle Dental legally available for
distribution to the shareholders after payment of all liabilities and amounts
owed to shareholders of Gentle Dental Preferred Stock. Holders of Gentle Dental
Common Stock are not entitled to preemptive or redemption rights.
 
    At September 30, 1998, Gentle Dental had 8,973,727 shares of Gentle Dental
Common Stock outstanding. In addition, options to purchase 1,292,304 shares of
Gentle Dental Common Stock had been granted under Gentle Dental's 1993 Stock
Incentive Plan (including certain option grants assumed in the merger with GMS
Dental Group, Inc.), but not exercised or terminated, leaving 690,390 shares
available for further grants under such plans.
 
GENTLE DENTAL PREFERRED STOCK
 
    Under the Gentle Dental Articles, the Gentle Dental Board of Directors is
authorized without further shareholder action to provide for the issuance of up
to 30 million shares of Gentle Dental Preferred in one or more series and to fix
the designations, number of shares, dividends, redemption rights, sinking fund
requirements, liquidation preferences and other rights, qualifications,
limitations or restrictions of any such series of preferred stock.
 
    As of September 30, 1998, Gentle Dental has designated the following series
of Gentle Dental Preferred: 100 shares of Gentle Dental Series A Preferred, all
of which are issued and outstanding; 70,000 shares of Gentle Dental Series B
Preferred, none of which are presently outstanding, but which will be issued
under certain circumstances that would cause an automatic conversion with
outstanding convertible notes of Gentle Dental into shares of Gentle Dental
Series B Preferred; 100 shares of Gentle Dental Series C Preferred, all of which
are issued and outstanding; and 2,000,000 shares of Gentle Dental Series D
Preferred, of which 1,628,664 shares are issued and outstanding.
 
    GENTLE DENTAL SERIES A PREFERRED.  The Gentle Dental Series A Preferred
ranks senior to the Gentle Dental Common Stock regarding liquidation, is equal
in preference with the Gentle Dental Series C Preferred but junior to all other
series of Gentle Dental Preferred. 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 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, 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. The shares of
Gentle Dental Series A Preferred have no conversion rights but may be redeemed
at the option of Gentle Dental under certain circumstances and must be redeemed
by Gentle
 
                                      103
<PAGE>
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 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 will be entitled to elect one additional individual to the Gentle
Dental Board of Directors.
 
    GENTLE DENTAL SERIES B PREFERRED.  Although there presently are no shares of
Gentle Dental Series B Preferred outstanding, if certain events of default on
Gentle Dental's 7% Convertible Subordinated Notes (the "Convertible Notes")
occur, the Convertible Notes then outstanding will automatically convert into
shares of Gentle Dental Series B Preferred at a rate of one share of Gentle
Dental Series B Preferred for each $1,000 in principal and accrued but unpaid
interest on such Convertible Notes, subject to adjustment for any
recapitalization, subdivision or recombination. The Gentle Dental Series B
Preferred 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 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 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 of $1,000, plus an additional amount, which amount
varies depending upon, among other things, (i) whether there exists an event of
default under the securities purchase agreement between Gentle Dental and the
holders of Gentle Dental Series B Preferred and (ii) the interest rate
applicable to the convertible subordinated notes of Gentle Dental, 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 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 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. 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 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 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
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 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 Washington Law, holders of
 
                                      104
<PAGE>
Gentle Dental Series B Preferred 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
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 into shares of Gentle Dental Common Stock.
 
    GENTLE DENTAL SERIES C PREFERRED.  The Gentle Dental Series C Preferred
ranks senior to the Gentle Dental Common Stock, equal to the Gentle Dental
Series A Preferred 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 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, an amount equal to $1.00 per share of such Gentle
Dental Series C Preferred, subject to adjustment in the event of any change in
the number and kind of shares of Gentle Dental Series C Preferred for any
recapitalization, subdivision or recombination. There is no dividend preference
for the holders of Gentle Dental Series C Preferred. The shares of series
preferred stock have no conversion rights. Upon the occurrence of certain
events, the holders of outstanding shares of Gentle Dental Series C Preferred
shall be entitled to elect one member of the Gentle Dental Board of Directors.
The holders of the Gentle Dental Series C Preferred generally are not entitled
to a shareholder's vote, except for a vote required under Washington Law or
under the Gentle Dental Articles. The holders of Gentle Dental Series C
Preferred are entitled to a separate vote on the Agreement and Mergers. The
shares of Gentle Dental Series C Preferred 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.  The Gentle Dental Series D Preferred
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 Gentle Dental Series C Preferred, but ranks junior to the
Gentle Dental Series B Preferred, 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 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.
 
    The holders of Gentle Dental Series D Preferred shall be entitled to
receive, when, as and if declared by the Gentle Dental Board, a cumulative
dividend of $.64 each dividend period, commencing February 17, 1999. In
addition, holders of Gentle Dental Series D Preferred 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 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. The redemption price per share is $9.21, plus
accumulated but unpaid 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 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.
 
                                      105
<PAGE>
    Each holder of a share of Gentle Dental Series D Preferred 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 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 Washington Law, the holders of Gentle Dental Series D
Preferred 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 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 into shares of Gentle Dental Common Stock.
 
    7% CONVERTIBLE SUBORDINATED NOTES.  On May 18, 1998 Gentle Dental issued
$25,500,000 of Convertible Notes and on June 3, 1998, Gentle Dental issued an
additional $4,500,000 of Convertible Notes. The Convertible 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 Notes. If certain
events of default occur, the Convertible Notes then outstanding will
automatically convert into shares of Gentle Dental Series B Preferred at a rate
of one share of Gentle Dental Series B Preferred for each $1,000 in principal
of, and accrued but unpaid interest on the Convertible Notes, subject to
adjustment for any recapitalization, subdivision or recombination. Under the
securities purchase agreement between Gentle Dental and the holders of the
Convertible Notes, the consent of the holders of a majority of the Gentle Dental
Common Stock equivalents issuable upon conversion of the Convertible Notes, is
required for approval of the Agreement and Mergers. In addition, Chase Venture
Capital Associates, one of the holders of the Convertible Notes, or its
successors or assigns, must consent to the Agreement and Mergers.

                     CERTAIN DIFFERENCES BETWEEN WASHINGTON
                          AND DELAWARE CORPORATE LAWS
 
    Washington Law governs the rights of Gentle Dental shareholders and Delaware
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.
Washington Law and Delaware 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 Law, 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, 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, is specified by the Board of Directors
as a condition to its recommendation of such amendment or is called for by a
provision of Washington Law. Under Washington Law and the Gentle Dental
Articles, each separate class or series of capital stock is entitled to a class
vote on certain extraordinary transactions, such as the Mergers and related
transactions described in the Agreement. See "--Class Voting" below.
 
    Under Delaware Law, amendments to the Dental Care Alliance and Wisdom
Holdings Certificate 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 Delaware 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 Delaware Law.
Amendments to the Articles of Dental Care Alliance 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 will
require the affirmative vote of at least a majority of the outstanding Wisdom
Holdings Capital Stock to approve an amendment. Also, under Delaware Law and the
Wisdom Holdings Certificate, 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 SHAREHOLDERS
 
    Washington Law 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,
Washington Law 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 Delaware Law, a special meeting of shareholders 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. Dental Care Alliance's Certificate provides that
special meetings may be called 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, only the Wisdom Holdings Board of Directors,
an authorized committee of members of the Board of Directors or
 
                                      107
<PAGE>
any other persons specified in any amendments to or designations under the
Wisdom Holdings' Certificate may call special meetings of the stockholders.
 
INDEMNIFICATION OF OFFICERS, DIRECTORS AND EMPLOYEES
 
    Under Washington Law, 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 Washington Law 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 authorize the corporation to indemnify any of its directors to
the fullest extent permitted by its By-laws (the "Gentle Dental By-Laws") and
Washington Law, including an advance of expenses. Generally, the Gentle Dental
By-Laws provide that Gentle Dental shall indemnify its directors, officers and
employees to the fullest extent permitted by Washington Law, 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 Delaware 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 Certificate and Dental Care Alliance Certificate each provide for the
indemnification of directors and officers to the fullest extent authorized by
Delaware Law.
 
PROVISIONS AFFECTING CONTROL SHARE ACQUISITIONS AND BUSINESS COMBINATIONS
 
    Washington Law 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 (an "Acquiring Person") 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 Washington State 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 domestic
corporations with their principal executive offices in Washington and either a
majority or over 1,000 of their employees residing in the State of Washington.
Gentle Dental does not believe that it
 
                                      108
<PAGE>
currently meets these standards or that it is subject to the statute. A
corporation may not "opt out" of this statute.
 
    Section 203 of Delaware 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;
 
                                      109
<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 Washington Law, 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 provide
for the affirmative vote of shareholders holding a majority of the outstanding
voting shares to approve such a transaction.
 
    Washington Law 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 provide for the
affirmative vote of shareholders holding a majority of the outstanding voting
shares to approve such a transaction.
 
    Under Delaware 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. The Dental Care Alliance Certificate does
      not contain a provision requiring a higher percentage of stockholder votes
      to approve such a transaction. The Wisdom Holdings Certificate of
      Incorporation does not require a higher percentage, except as described
      under "--Comparison of Rights of Gentle Dental Shareholders" and "Wisdom
      Holdings Stockholders--Interested Shareholders" above.
 
ACTION WITHOUT A MEETING
 
    Under Washington Law, 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
 
                                      110
<PAGE>
shareholders entitled to vote thereon. The Gentle Dental By-Laws provide for
shareholder action without a meeting and by written consent.
 
    Under the Delaware 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 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 Washington Law, 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 authorize the issuance of
future series of Gentle Dental Preferred Stock. Generally, each series is vested
with class voting rights regarding (i) the issuance or authorization of any
additional class of equity stock ranking prior to the series affected and (ii)
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, one hundred shares of Gentle Dental
Series C Preferred and 1,628,633 shares of Gentle Dental Series D Preferred are
presently issued and outstanding and each series is entitled to such class vote
to approve the Agreement and Mergers.
 
    Delaware 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, Wisdom
Holdings Series C Preferred and Wisdom Holdings Series D Preferred that will be
deemed outstanding at the Effective Time will each be entitled to a class vote
regarding (i) 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 (ii) 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
 
    Washington Law 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: (i) it is approved by
a majority of qualified directors (but no fewer than two); (ii) it is approved
by the affirmative vote of the majority of all qualified shares after notice and
disclosure to the shareholders; or (iii) 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 Delaware 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,
 
                                      111
<PAGE>
are met. Under Delaware 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).
 
DISSENTERS' OR APPRAISAL RIGHTS
 
    Under Washington Law, 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 Delaware 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 Washington Law, 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, (i) the corporation would not
be able to pay its debts as they become due in the usual course of business or
(ii) 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.
 
    Delaware 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, Delaware 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' APPRAISAL RIGHTS
 
    The Agreement constitutes a plan of merger for which shareholder approval is
required under Washington Law. Pursuant to Section 23B.3.010 through 23B.13.310
of Washington Law, any shareholder of Gentle Dental who gives proper notice and
who does not vote in favor of the Merger will, upon proper demand, have the
right under Washington Law 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 Agreement. As provided
in Section 23B.13.030 of Washington Law, 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 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 AGREEMENT WILL CONSTITUTE A WAIVER OF
DISSENTERS' RIGHTS. A VOTE AGAINST THE 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 of Washington Law 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 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 Agreement. The
notice will provide, among other things:
 
    -  (i) the form of payment demand (including the date of the first
       announcement to the shareholders of the terms of the Mergers),
 
    -  (ii) where the payment demand must be delivered,
 
    -  (iii) when and where the certificated shares must be deposited, and
 
    -  (iv) 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 Washington Law 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 defined 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
 
                                      113
<PAGE>
estimates to be the fair value of their shares of Gentle Dental Common Stock,
together with any interest 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 as the date of the first
shareholders Gentle Dental ("Gentle Dental After-Acquired Shares"), Wisdom
Holdings may elect to withhold the payment described in the preceding paragraph
and to offer to pay fair value for the 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 Washington Law, a copy of which is
attached to this Joint Proxy Statement-Prospectus as Appendix D.
 
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.

           UNAUDITED PRO FORMA COMBINED FINANCIAL AND OPERATING DATA
 
    The Unaudited Pro Forma Combined Balance Sheet and Pro Forma Combined
Statement 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 six month period ended June 30, 1998 and the
financial statements of the entities involved in affiliations completed during
1997 and 1998, and the Pending Affiliations. The Pro Forma Consolidated
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
Consolidated Financial Data for the year ended December 31, 1997 and the six
month period ended June 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 Consolidated Statement of Operations Data for the year ended
December 31, 1997 and the six month period ended June 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 affiliations and the Pending Affiliations (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
Consolidated 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 CONSOLIDATED FINANCIAL DATA
 
    The accompanying pro forma consolidated financial data presents the pro
forma financial position of Wisdom as of June 30, 1998 and the pro forma results
of operations for the years ended December 31, 1995, 1996, and 1997 and the six
month period ended June 30, 1998.
 
    The pro forma consolidated 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 October 22, 1998, Gentle Dental acquired 20
dental practices in acquisitions accounted for as purchases and had additional
acquisitions pending. The accompanying Pro Forma Consolidated Balance Sheet as
of June 30, 1998 includes the effect of the 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 and the Pending Affiliations, as if they
had been completed at June 30, 1998. The accompanying Pro Forma Consolidated
Statements of Operations for the six months ended June 30, 1998 and the year
ended December 31, 1997 include the affects of the acquisitions, including their
results of operations, amortization of intangible assets acquired and the impact
of financing the acquisitions, as if they had been completed on January 1, 1997.
 
    From January 1, 1997 through October 22, 1998, Dental Care Alliance acquired
2 dental practice management companies in acquisitions accounted for as
purchases.
 
    The pro forma adjustments reflected in the Condensed Pro Forma Consolidated
Balance Sheet and Pro forma Consolidated Statements of Operations are as
follows:
 
a)  Reflects certain balance sheet and statement of operations items associated
    with acquired (from an accounting point of view) dental practices or
    acquired dental practice management companies for completed transactions
    during the period from January 1, 1997 to October 29, 1998. The balance
    sheet reflects the pro forma effect of the acquisitions assuming that such
    transactions which closed subsequent to June 30, 1998 were consummated on
    June 30, 1998. The statements of operations reflect the pro forma effect of
    the acquisitions assuming that such transactions had occurred on January 1,
    1997.
 
b)  Reflects the statement of operations impact of the issuance of convertible
    debt and convertible preferred stock in May and June of 1998 as if such debt
    and preferred stock had been issued on January 1, 1997. Also, reflects the
    balance sheet and related statement of operations impact of adjustments
    necessary to reflect the acquisition costs and intangible assets associated
    with the completed acquisitions. These costs include interest expense
    associated with the cost of the transaction, amortization associated with
    intangible assets and the tax effect thereof. Intangible assets include the
    value assigned to management agreements and other acquired intangible
    assets.
 
c)  Reflects certain balance sheet and related statement of operations items
    associated with the pending dental practice acquisitions.
 
d)  Reflects the balance sheet and related statement of operations impact of
    adjustments necessary to reflect the acquisition costs and intangible assets
    associated with the pending dental practice acquisitions. Acquisition costs
    include interest expense associated with the cost of the transaction,
    amortization associated with intangible assets and the tax effect thereof.
    Intangible assets include the value assigned to management agreement and
    other acquired intangible assets.
e)  Reflects adjustments necessary to show the impact of consolidating the
    results of operations of certain previously unconsolidated dental practices.
    Also reflects the reduction of clinical salaries and benefits
 
                                      F-8
<PAGE>
    associated with the amendments made to the underlying management agreements
    with these dental practices assuming that such transactions had occurred on
    January 1, 1997.
 
f)  Reflects the changes in compensation paid to former dentist owners of dental
    practices acquired.
 
g)  Reflects the impact of reducing or changing certain expenses of acquired
    dental practices that are expected to be nonrecurring.
 
h)  Reflects changes in depreciation and amortization expenses associated with
    conforming the accounting policies and methodologies of the completed and
    pending dental practice acquisitions with those of the Company, based upon
    the fair value of assets acquired for acquisitions accounted for as
    purchases and historical cost for the merger of Gentle Dental and Dental
    Care Alliance.
 
i)  Reflects the change in income tax expense assuming a 40% income tax rate on
    income before income taxes.
 
j)  Reflects the elimination of dividends on shares of redeemable preferred
    stock assuming that such redeemable preferred stock was converted into
    common stock on January 1, 1997.
 
k)  Reflects shares issued in connection with acquisitions.
 
l)  Reflects dilutive shares as a result of pro forma adjustments resulting in
    income and dilutive effect of preferred stock and convertible debt.
 
m) Reflects additional shares issued based upon exchange ratio of 1.67 shares
    per share of DCA common stock.
 
n)  Includes patient service revenue for affiliated dental practices, including
    consolidated and unconsolidated practices. Practices which have affiliated
    with DCA, but are not accounted for as acquisitions, had patient revenue of
    $25 million for the year ended December 31, 1997 and $4 million for the six
    months ended June 30, 1998, prior to the date of affiliation with DCA. Such
    amounts are not included in the patient level revenue as reported.

                          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.

(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)

(2) BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    SUPPLIES
 
    Supplies consist primarily of disposable dental supplies and instruments
stored at the clinics. Supplies are stated at the lower of cost (first-in,
first-out basis) or market (net realizable value).
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost net of accumulated depreciation
and amortization. Expenditures for maintenance and repairs are charged to
expense as incurred and expenditures for additions and betterments are
capitalized. Equipment held under capital leases is stated at the present value
of minimum lease payments at the inception of the lease. Depreciation of
property and equipment is recorded using the straight-line method over the
shorter of the related lease term or the estimated useful lives which generally
range from 3 to 15 years.
 
    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.
 
    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.

(2) BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities,
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

    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

(6) DEBT
 
    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 1997 at a
purchase price of $.225 per share 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.

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.
 
(2) SIGNIFICANT ACCOUNTING POLICIES
 
    (A) BASIS OF PRESENTATION
 
       The accompanying financial statements have been prepared on the accrual
       basis of accounting and include the combined accounts of DMO and CDC
       (collectively referred to as the Company).
 
    (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.
 
    (C) CASH AND CASH EQUIVALENTS AND INVESTMENTS
 
       The Company considers all highly liquid investments in debt instruments
       with an original maturity of three months or less to be cash equivalents.
 
       Investments primarily represent certificates of deposit at various
       financial institutions. Cash and investment balances in excess of amounts
       insured by the Federal Deposit Insurance Corporation approximate $2,748
       at December 31, 1997.
 
    (D) ACCOUNTS RECEIVABLE
 
       Accounts receivable represent amounts due from patients and other third
       party payors for dental services provided by the dental groups. Amounts
       are recorded net of contractual allowances.
 
    (E) EQUIPMENT AND LEASEHOLD IMPROVEMENTS
 
       Equipment and leasehold improvements are stated at cost. Expenditures for
       maintenance and repairs are charged to expense as incurred and
       expenditures for additions and betterments are capitalized. Depreciation
       of equipment is recorded using the straight-line method over five to ten
       years, the estimated useful lives of the assets. Leasehold improvements
       are amortized on the straight-line method over the shorter of the lease

    (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 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.

(2) SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    (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,
       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) 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 groups which might have a material impact on the
    Company's financial position or results or operations.
 
(4) COMMITMENTS AND CONTINGENCIES
 
    (A) LEASE COMMITMENTS
 
       The Company has entered into operating leases of commercial property.
       Commercial properties under operating leases mostly include space
       required to perform dental services and space for administrative
       facilities. Lease expense for office space for the years ended December
       31, 1997 and 1996 was $309 and $222, respectively.

                AGREEMENT AND PLAN OF REORGANIZATION AND MERGER
 
    THIS AGREEMENT AND PLAN OF REORGANIZATION AND MERGER, dated as of October
15, 1998 (this "AGREEMENT"), by and among Wisdom Holdings, Inc., a Delaware
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.
 
    B.  DCA is a Delaware corporation, having its principal place of business in
Sarasota, Florida. DCA provides dental practice management and related services
to dental practices in the States of Florida, Georgia, Indiana and Michigan.
 
    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

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:

Subsidiaries are or may become required to be issued (other than to it or its
wholly-owned Subsidiaries) by reason of any Right or otherwise, (iv) there are
no contracts, commitments, understandings or arrangements by which any of such
Subsidiaries is or may be bound to sell or otherwise transfer any equity
securities of any such Subsidiaries (other than to it or its wholly-owned
Subsidiaries), (v) there are no contracts, commitments, understandings, or
arrangements relating to its rights to vote or to dispose of such securities,
and (vi) all the equity securities of each Subsidiary held by GDSC or its

Subsidiaries free and clear of any Liens.
 
    (b) GDSC does not own beneficially, directly or indirectly, any equity
securities or similar interests of any Person, or any interest in a partnership
or joint venture of any kind, other than its Subsidiaries.
 
    (c) Each of GDSC's Subsidiaries has been duly organized and is validly
existing in good standing under the laws of the jurisdiction of its
organization, and is duly qualified to do business and in good standing in the
jurisdictions where its ownership or leasing of property or the conduct of its
business requires it to be so qualified.

    orders or decrees applicable thereto or to the employees conducting such
    businesses;

       (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

    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

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,

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

two-digit or four-digit dates and date-related input in a way that resolves any

are unambiguous as to the year 2000; and (iv) suitably interact with other
software and related hardware in a way which does not compromise its year 2000
compliance capability.

applicable Environmental Laws; (i) no real property (including buildings or
other structures) currently or formerly owned, leased or operated by GDSC or any

polychlorinated biphenyls, prior manufacturing operations, dry-cleaning, or
automotive services) involving GDSC or any of its Subsidiaries, any currently or

Subsidiaries or result in any restrictions on the ownership, use, or transfer of
any property pursuant to any Environmental Law; and (vi) GDSC has delivered to
DCA copies of all environmental reports, studies, sampling data, correspondence,

<PAGE>
    (b) As used herein, the term "ENVIRONMENTAL LAW" means any federal, state or
local law, regulation, order, decree, permit, authorization, opinion, common law

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

Subsidiaries are not in material default thereunder; and all claims thereunder
have been filed in due and timely fashion.

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),
 
                                      A-14
<PAGE>
and each such contract is in full force and effect. The Assets of GDSC and its
Subsidiaries include all assets required to operate the business of GDSC and its
Subsidiaries as presently conducted.
 
    4.22.  STATEMENTS TRUE AND CORRECT.  None of the information supplied or to
be supplied by GDSC 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
GDSC or any of its Subsidiaries for inclusion in the Proxy Statement to be
mailed to GDSC's or DCA's stockholders in connection with the GDSC Meeting or

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 GDSC Meeting or the DCA 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 GDSC Meeting or the DCA Meeting. All documents
that GDSC 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.
 
    4.23.  ACCOUNTING, TAX AND REGULATORY.  Neither GDSC 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 hereby, including the Merger, from qualifying for
pooling-of-interests accounting treatment or as (i) 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 4.6(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.
 
    4.24.  NO UNDISCLOSED LIABILITIES.  Except as set forth in the financial
statements filed in connection with the GDSC SEC Reports or Previously
Disclosed, GDSC does not have any material liability or obligation accrued,
contingent or otherwise.

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

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:
 
    5.1.  ORGANIZATION, STANDING AND AUTHORITY.  DCA is a corporation duly

leasing of property or assets or the conduct of its business requires it to be
so qualified. The DCA Board has received the written opinion of Raymond James &
Associates, Inc. to the effect that as of the date hereof the DCA Exchange Ratio
is fair to the holders of DCA Common Stock from a financial point of view.

Subsidiaries is or may be bound to sell or otherwise transfer any equity

securities or similar interests of any Person, or any interest in a partnership
or joint venture of any kind, other than its Subsidiaries.
 
    (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
organization, and is duly qualified to do business and in good standing in the
jurisdictions where its ownership or leasing of property or the conduct of its
business requires it to be so qualified.
 
    5.3.  DCA COMMON STOCK.  As of the date hereof, the authorized capital stock
of DCA consists solely of 50,000,000 shares of DCA Common Stock of which
7,031,066 are issued and outstanding and 5,000,000 shares of DCA Preferred Stock
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
outstanding, fully paid and nonassessable, subject to no preemptive rights and
were not issued in violation of any preemptive rights. As of the date hereof,
there are 613,014 shares of DCA Common Stock authorized and reserved for

                                      A-16
<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
own all its properties and assets; and DCA has the corporate power and authority
to execute, deliver and perform its obligations under this Agreement and to
consummate the transactions contemplated hereby.
 
    5.5.  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 DCA Common Stock
entitled to vote thereon (which is the only stockholder vote required thereon),
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,
reorganization, moratorium, fraudulent transfer and similar laws of general
applicability relating to or affecting creditors' rights or by general equity
principles).
 
    5.6.  CONSENTS AND APPROVALS; NO DEFAULTS.
 
    (a) No consents or approvals of, or filings or registrations with, any
Governmental Authority or with any third party are required to be made or
obtained by DCA or any of its Subsidiaries in connection with the execution,
delivery or performance by DCA of this Agreement or to consummate the Merger
except for (i) filings of applications, registrations, statements, reports or
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
Delaware Secretary pursuant to the DGCL. As of the date hereof, DCA is not aware
of any reason why the approvals set forth in SECTION 11.1(d) will not be
received without the imposition of a condition, restriction or requirement of
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 DCA or of any of its Subsidiaries or to
which DCA or any of its Subsidiaries or properties is subject or bound, (ii)
constitute a breach or violation of, or a default under, the DCA Certificate of
Incorporation or the DCA Bylaws, or (iii) require any consent or approval under

as of June 30, 1998, and the related unaudited statements of income, cash flows
and changes in financial position of DCA for quarters ended March 31, 1998, and

    (b) DCA has timely filed all reports, registrations and statements, together
with any amendments required to be made with respect thereto, that they were
required to file since November 4, 1997, the date of DCA's initial public

December 31, 1996, including, without limitation, any report or statement
required to be filed pursuant to the laws of the United States or the State of
Delaware, and has paid all fees and assessments due and payable in connection
therewith. As
 
                                      A-17
<PAGE>
of their respective dates, such reports, registrations and statements complied
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
superseded by a filing prior to the date of this Agreement, then on the date of
such filing) contain any untrue statement of a material fact or omit to state a
material fact required to be stated in such DCA SEC Reports or necessary in
order to make the statements in such DCA SEC Reports, in light of the

Subsidiaries is required to file any forms, reports or other documents with the

Authority.
 
    (b) Neither DCA nor any of its Subsidiaries has been advised by any
Governmental Authority that such Governmental Authority is contemplating issuing
or requesting (or is considering the appropriateness of issuing or requesting)
any such order, decree, agreement, memorandum of understanding, commitment
letter or similar action.
 
    5.10.  COMPLIANCE WITH LAWS.
 
    (a) DCA 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 DCA'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 DCA 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 DCA's knowledge, do any grounds for any of the
    foregoing exist).
 
    (b) The terms and conditions set forth in the management agreements between
DCA or its Subsidiaries and the dental practices managed by such entities comply
in all material respects with
 
                                      A-18
<PAGE>
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.
 
    5.11.  MATERIAL CONTRACTS; DEFAULTS.  Neither DCA 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 DCA
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.
 
    5.12.  NO BROKERS.  Except for commissions, fees and other like payments due
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
commission, finder's fee or other like payment with respect to the transactions
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
liability thereunder.
 
    (g) The consummation of the transactions contemplated by this Agreement will
not (x) entitle any employees of DCA or any of its Subsidiaries to severance
pay, (y) 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 DCA Benefit Plans or (z) result in
any breach or violation of, or a default under, any of the DCA Benefit Plans.
Without limiting the foregoing, as a result of the consummation of the
transactions contemplated by this Agreement, neither DCA 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 whether such payment is
reasonable compensation for personal services performed or to be performed in
the future.
 
    5.14.  LABOR MATTERS.  Neither DCA 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 DCA 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 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
Subsidiaries pending or, to DCA's knowledge, threatened, nor is DCA 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.
 
    5.15.  YEAR 2000 COMPLIANCE.  Except as Previously Disclosed, (i) the
computer software and related hardware of DCA and its Subsidiaries (the "DCA
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 DCA,
all of the suppliers, customers and third party providers of DCA are, or will be
prior to year 2000, Year 2000 Compliant; and (iii) DCA is taking or has taken,
all commercially reasonable and appropriate action to address and remedy any
deficiencies in the DCA Computer System which would keep it from becoming Year
2000 Compliant.
 
                                      A-20
<PAGE>
    5.16.  ENVIRONMENTAL MATTERS.
 
    (a) DCA and each of its Subsidiaries has complied at all times with
applicable Environmental Laws; (i) no real property (including buildings or
other structures) currently or formerly owned, leased or operated by DCA or any
of its Subsidiaries, has been contaminated with, or has had any release of, any
Hazardous Substance; (ii) neither DCA nor any of its Subsidiaries is subject to
liability for any Hazardous Substance disposal or contamination on any third
party property; (iii) neither DCA nor any of its Subsidiaries has received any
notice, demand letter, claim or request for information alleging any violation
of, or liability under, any Environmental Law; (iv) neither DCA nor any of its
Subsidiaries is subject to any order, decree, injunction or other agreement with
any Governmental Authority or any third party relating to any Environmental Law;
(v) to the best of DCA's knowledge, there are no circumstances or conditions
(including the presence of asbestos, underground storage tanks, lead products,
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
currently or formerly owned, leased or operated property.
 
    5.17.  TAX MATTERS.
 
    (a)(i)All Tax Returns that are required to be filed (taking into account any
extensions of time within which to file) by or with respect to DCA and its
Subsidiaries have been duly filed, (ii) all Taxes due have been paid in full,
(iii) all deficiencies asserted or assessments made as a result of such
examinations have been paid in full, (iv) no issues that have been raised by the
relevant taxing authority in connection with the examination of any of the Tax
Returns referred to in clause (i) are currently pending, and (v) no waivers of
statutes of limitation have been given by or requested with respect to any Taxes
of DCA or its Subsidiaries. DCA has made available to GDSC true and correct
copies of the United States federal income Tax Returns filed by DCA and its
Subsidiaries for each of the three most recent fiscal years ended on or before
December 31, 1997. Neither DCA nor any of its Subsidiaries has any liability
with respect to income, franchise or similar Taxes that accrued on or before the
end of the most recent period covered by DCA's Regulatory Documents filed prior
to the date hereof in excess of the amounts accrued with respect thereto that
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
an affiliated group filing consolidated or combined Tax returns (other than a
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,
free and clear of all Liens, to all of their respective Assets. All tangible
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

    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

    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>

    Effect on the other party or ParentCo.

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

    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.

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.

    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,

                        FORM OF STOCKHOLDERS' AGREEMENT
                    ----------------------------------------

dated as of the date hereof (the "MERGER AGREEMENT"), providing for the business
combination transactions (the "MERGER") contemplated therein.
 
    B.  Stockholder owns the shares of [     ] Capital Stock identified on ANNEX
I hereto (such shares, together with all shares of [     ] Capital Stock
subsequently acquired by the Stockholder during the term of this Agreement,
being referred to as the "SHARES"); and
 
    C.  In order to induce ParentCo, GDSC, GDSC Acquisition Corp., DCA and DCA

    1.  AGREEMENT TO VOTE SHARES.  Stockholder shall vote or cause to be voted,

favor of adoption and approval of the principal terms of the Merger Agreement
and all transactions contemplated thereby at every meeting of the Stockholders
of [     ] at which such matters are considered and presented for vote, if any,
and at every adjournment thereof and in connection with every proposal to take
action by written consent with respect thereto. This Agreement is intended to
bind Stockholder only with respect to the specific matters set forth herein, and
shall not prohibit Stockholder from acting in accordance with his fiduciary
duties as an officer or director of [     ]. Stockholder will retain at all
times the right to vote the Shares, in Stockholder's sole discretion, on all
matters other than those set forth in this Section 1 including, without
limitation, any other merger or transaction involving [     ], which are at any
time or from time to time presented to [     's] Stockholders generally.
 
    2.  NO VOTING TRUSTS.  Stockholder agrees that Stockholder will not, nor
will Stockholder permit any entity under Stockholder's control to, deposit any
Shares in a voting trust or subject the Shares to any agreement, arrangement or
understanding with respect to the voting of the Shares inconsistent with this
Agreement.
 
    3.  LIMITATION ON SALES.  Stockholder agrees not to sell shares of [     ]
Capital Stock, or ParentCo Capital Stock once received, for a period beginning
thirty (30) days prior to consummation of the Merger and ending on the date that

                                      D-1
<PAGE>
results of operations are published. Stockholder hereby consents to having
appropriate legends placed in the certificates representing such shares of
ParentCo Capital Stock issued in the Merger relating to such restriction or
transfer.
 
    4.  REPRESENTATIONS AND WARRANTIES OF STOCKHOLDER.  Stockholder represents
and warrants to and further agrees as follows:
 
        (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
personally, upon receipt of a transmission confirmation if sent by telecopy or

required by RCW 23B.13.200 through 23B.13.280.
 
(3) "Fair value," with respect to a dissenter's shares, means the value of the
shares immediately before the effective date of the corporate action to which
the dissenter objects, excluding any appreciation or depreciation in
anticipation of the corporate action unless exclusion would be inequitable.
 
(4) "Interest" means interest from the effective date of the corporate action
until the date of payment, at the average rate currently paid by the corporation
on its principal bank loans or, if none, at a rate that is fair and equitable
under all the circumstances.
 
(5) "Record shareholder" means the person in whose name shares are registered in
the records of a corporation or the beneficial owner of shares to the extent of
the rights granted by a nominee certificate on file with a corporation.
 
(6) "Beneficial shareholder" means the person who is a beneficial owner of
shares held in a voting trust or by a nominee as the record shareholder.
 
(7) "Shareholder" means the record shareholder or the beneficial shareholder.
 
23B.13.020. RIGHT TO DISSENT
 
(1) A shareholder is entitled to dissent from, and obtain payment of the fair
value of the shareholder's shares in the event of, any of the following
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;
 
    (b) Consummation of a plan of share exchange to which the corporation is a
party as the corporation whose shares will be acquired, if the shareholder is
entitled to vote on the plan;
 
    (c) Consummation of a sale or exchange of all, or substantially all, of the
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,
including a sale in dissolution, but not including a sale pursuant to court
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
year after the date of sale;
 
                                      E-1
<PAGE>
    (d) An amendment of the articles of incorporation that materially reduces
the number of shares owned by the shareholder to a fraction of a share if the
fractional share so created is to be acquired for cash under RCW 23B.06.040; or
 
    (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.
 
(3) The right of a dissenting shareholder to obtain payment of the fair value of
the shareholder's shares shall terminate upon the occurrence of any one of the
following events:
 
    (a) The proposed corporate action is abandoned or rescinded;
 
    (b) A court having jurisdiction permanently enjoins or sets aside the
corporate action; or
 
    (c) The shareholder's demand for payment is withdrawn with the written
consent of the corporation.
 
23B.13.030. DISSENT BY NOMINEES AND BENEFICIAL OWNERS
 
(1) A record shareholder may assert dissenters' rights as to fewer than all the
shares registered in the shareholder's name only if the shareholder dissents
with respect to all shares beneficially owned by any one person and notifies the
corporation in writing of the name and address of each person on whose behalf
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.
 
(2) A beneficial shareholder may assert dissenters' rights as to shares held on
the beneficial shareholder's behalf only if:
 
    (a) The beneficial shareholder submits to the corporation the record
shareholder's written consent to the dissent not later than the time the
beneficial shareholder asserts dissenters' rights; and
 
    (b) The beneficial shareholder does so with respect to all shares of which
such shareholder is the beneficial shareholder or over which such shareholder
has power to direct the vote.
 
23B.13.200. NOTICE OF DISSENTERS' RIGHTS

<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),
 
                                      II-7
<PAGE>
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.

                   CERTIFICATE OF AMENDMENT OF CERTIFICATE
                      OF INCORPORATION BEFORE PAYMENT OF
                           ANY PART OF THE CAPITAL
                                      OF
                            WISDOM HOLDINGS, INC.


     WISDOM HOLDINGS, INC. (hereinafter called the "Corporation"), a 
corporation organized and existing under and by virtue of the General 
Corporation Law of the State of Delaware, does hereby certify:

     1.   The name of the corporation is WISDOM HOLDINGS, INC.
     
     2.   The corporation has not received any payment for any of its stock.
     
     3.   The Certificate of Incorporation of the Corporation is hereby 
amended by adding the following new Article XIV:

          A.   The Corporation shall, to the broadest and maximum extent
     permitted by Delaware law, as the same exists from time to time indemnify
     each person who was or is a party or is threatened to be made a party to
     any threatened, pending or completed action, suit or proceeding, whether
     civil, criminal, administrative or investigative by reason of the fact that
     he or she is or was a director or officer of the Corporation, or is or was
     serving at the request of the Corporation as a director, officer, employee
     or agent of another corporation, partnership, joint venture, trust or other
     enterprise, against expenses (including attorneys' fees), judgments, fines
     and amount paid in settlement actually and reasonably incurred by him or
     her in connection with such action or proceeding. 

          B.   In addition, the Corporation shall, to the broadest and maximum
     extent permitted by Delaware law, as the same may exist from time to time
     pay to such person any and all expenses (including attorneys' fees)
     incurred in defending or settling any such action, suit or proceeding in
     advance of the final disposition of such action, suit or proceeding upon
     receipt of an undertaking by or on behalf of the director or officer to
     repay such amount if it shall ultimately be determined by a final judgment
     or other final adjudication that he or she is not entitled to be
     indemnified by the Corporation as authorized in this Article XIV. 

          C.   Subsections (A) and (B) of this Article XIV to the contrary
     notwithstanding, the Corporation shall not indemnify any such person with
     respect to any of the following matters:  (i) remuneration paid to such
     person if it shall be determined by a final judgment or other final
     adjudication that such remuneration was in violation of law; or (ii) any
     accounting of profits made from the purchase or sale by such person of the
     Corporation's securities within the meaning of Section 16(b) of the
     Securities Exchange Act of 1934 and amendments thereto or similar
     provisions of any federal, state or local statutory law, or (iii) actions
     brought about or contributed to by the dishonesty of such person, if a
     final judgment or other final adjudication adverse to such person
     establishes that acts of active and deliberate dishonesty were committed or
     attempted by such person with actual dishonest purpose and intent and were
     material to the adjudication; or (iv) actions based on or attributable to
     such person having gained any personal profit or advantage to which he or
     she was not entitled, in the event that a final judgment or other final
     adjudication 

                                       -1-

<PAGE>

     adverse to such person establishes that such person in fact gained such 
     personal profit or other advantage to which he or she was not entitled; or
     (v) any matter in respect of which a final decision by a court with 
     competent jurisdiction shall determine that indemnification is unlawful. 

          D.   The rights to indemnification and to the advancement of expenses
     conferred in this Article XIV shall not be exclusive of any other right
     which any person may have or hereafter acquire under any statute, the
     Certificate of Incorporation, this amendment of the Certificate of
     Incorporation, the Bylaws of the Corporation, by agreement, vote of
     stockholders, or disinterested directors or otherwise. 

     4.   The amendment of the Certificate of Incorporation of the Corporation
herein certified was duly adopted, pursuant to the provisions of Section 241 of
the General Corporation Law of the State of Delaware, by the sole incorporator,
no directors having been named in the Certificate of Incorporation and no
directors having been elected.  

Executed on this 14th day of October, 1998.

     Section 5.     NOTICE OF SPECIAL MEETINGS.  As soon as reasonably 
practicable after receipt of a request as provided in Section 4 of this 
Article II, written notice of a special meeting, stating the place, date 
(which shall be not less than ten (10) nor more than sixty (60) days from the 
date of the notice) and hour of the special meeting and the purpose or 
purposes for which the special meeting is called, shall be given to each 
stockholder entitled to vote at such special meeting.

     Section 6.     SCOPE OF BUSINESS AT SPECIAL MEETING.  Business 
transacted at any special meeting of stockholders shall be limited to the 
purposes stated in the notice.

     Section 7.     QUORUM.  The holders of a majority of the stock issued 
and outstanding and entitled to vote thereat, present in person or 
represented by proxy, shall constitute a quorum at all meetings of the 
stockholders for the transaction of business, except as otherwise provided by 
statute or by the Certificate of Incorporation.  If, however, such quorum 
shall not be present or represented at any meeting of the stockholders, the 
chairman of the meeting or the stockholders entitled to vote thereat, present 
in person or represented by proxy, shall have power to adjourn the meeting 
from time to time, without notice other than announcement at the meeting, 
until a quorum shall be present or represented.  At such adjourned meeting at 
which a quorum shall be present or represented, any business may be 
transacted which might have been transacted at the meeting as originally 
notified.  If the adjournment is for more than thirty (30) days, or if after 
the adjournment a new record date is fixed for the adjourned meeting, a 
notice of the adjourned meeting shall be given to each stockholder of record 
entitled to vote at the meeting as provided in Section 5 of this Article II.

     Section 8.     QUALIFICATIONS TO VOTE.  The stockholders of record on 
the books of the corporation at the close of business on the record date as 
determined by the Board of Directors and only such stockholders shall be 
entitled to vote at any meeting of stockholders or any adjournment thereof.

     Section 9.     RECORD DATE.  The Board of Directors may fix a record 
date for the determination of the stockholders entitled to notice of or to 
vote at any stockholders' meeting and at any adjournment thereof, and to fix 
a record date for any other purpose.  The record date shall not be more than 
sixty (60) nor less than ten (10) days before the date of such meeting.  If 
no record date is fixed by the Board of Directors, the record date for 
determining stockholders entitled to notice of or to vote at a meeting of 
stockholders shall be at the close of business on the day next preceding the 
day on which notice is given, or if notice is waived, at the close of 
business on the day next preceding the day on which the meeting is held.  A 
determination of stockholders of record entitled to notice of or to vote at a 
meeting of stockholders shall apply to any adjournment of the meeting; 
provided, however, that the Board of Directors may fix a new record date for 
the adjourned meeting.

     Section 10.    ACTION AT MEETINGS.  When a quorum is present at any 
meeting, the vote of the holders of a majority of the stock having voting 
power present in person or represented by proxy shall decide any question 
brought before such meeting, unless the question is one upon which by express 
provision of applicable law or of the Certificate of Incorporation, a 
different vote is required, in which case such express provision shall govern 
and control the decision of such question. 

     Section 11.    VOTING AND PROXIES.  Unless otherwise provided in the 
Certificate of Incorporation, each stockholder shall at every meeting of the 
stockholders be entitled to one (1) vote in person or by proxy for each share 
of the capital stock having voting power held by such stockholder, but no 
proxy shall be voted on after three (3) years from its date, unless the proxy 
provides for a longer period.  Each proxy shall be revocable unless expressly 
provided therein to be irrevocable and unless it is coupled with an interest 
sufficient in law to support an irrevocable power

                                  INDEMNIFICATION

     Section 1.     SCOPE.  The corporation shall, to the fullest extent
permitted by Section 145 of the Delaware General Corporation Law, as that
Section may be amended and supplemented from time to time, indemnify any
director, officer, employee or agent of the corporation, against expenses
(including attorneys' fees), judgments, fines, amounts paid in settlement and/or
other matters referred to in or covered by that Section, by reason of the fact
that he is or was a director, officer, employee or agent of the corporation, or
is or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise.

     Section 2.     ADVANCING EXPENSES.  Expenses incurred by a director of 
the corporation in defending a civil or criminal action, suit or proceeding

agent of the corporation (or is or was serving at the request of the 
corporation as a director, officer, employee or agent of another corporation, 
partnership, joint venture, trust or other enterprise) shall be paid by the 
corporation in advance of the final disposition of such action, suit or 
proceeding upon receipt of an undertaking by or on behalf of such director to 
repay such amount if it shall ultimately be determined that he is not 
entitled to be indemnified by the corporation as authorized by relevant 
provisions of the Delaware General Corporation Law; provided, however, the 
corporation shall not be required to advance such expenses to a director (i) 
who commences any action, suit or proceeding as a plaintiff unless such 
advance is specifically approved by a majority of the Board of Directors, or 
(ii) who is a party to an action, suit or proceeding brought by the 
corporation and approved by a majority of

or any other willful and deliberate breach in bad faith of such director's 
duty to the corporation or its stockholders.

     Section 3.     LIABILITY OFFSET.  The corporation's obligation to provide
indemnification under this Article VIII shall be offset to the extent the
indemnified party is indemnified by any other source including, but not limited
to, any applicable insurance coverage under a policy maintained by the
corporation, the indemnified party or any other person.

     Section 4.     CONTINUING OBLIGATION.  The provisions of this Article VIII
shall be deemed to be a contract between the corporation and each director of
the corporation who serves in such capacity at any time while this bylaw is in
effect, and any repeal or modification thereof shall not affect any rights or
obligations then existing with respect to any state of facts then or theretofore
existing or any action, suit or proceeding theretofore or thereafter brought
based in whole or in part upon any such state of facts.

     Section 5.     NONEXCLUSIVE.  The indemnification and advancement of
expenses provided for in this Article VIII shall (i) not be deemed exclusive of
any other rights to which those indemnified may be entitled under any by-law,
agreement or vote of stockholders or disinterested directors or otherwise, both
as to action in their official capacities and as to action in another capacity
while holding such office, (ii) continue as to a person who has ceased to be a
director and (iii) inure to the benefit of the heirs, executors and
administrators of such a person.

     Section 6.     OTHER PERSONS.  In addition to the indemnification rights of
directors, officers, employees, or agents of the corporation, the Board of
Directors in its discretion shall have the power on behalf of the corporation to
indemnify any other person made a party to any action, suit or proceeding who
the corporation may indemnify under Section 145 of the Delaware General
Corporation Law.

     Section 7.     DEFINITIONS.  The phrases and terms set forth in this
Article VIII shall be given the same meaning as the identical terms and phrases
are given in Section 145 of the Delaware General Corporation Law, as that
Section may be amended and supplemented from time to time.

                                     ARTICLE IX 
                                          
                                     AMENDMENTS

     Except as otherwise provided in the Certificate of Incorporation, these
Bylaws may be altered, amended or repealed, or new Bylaws may be adopted, by the
holders of a majority of the outstanding voting shares or by the Board of
Directors, when such power is conferred upon the Board of Directors by the
Certificate of Incorporation, at any regular meeting of the stockholders or of
the Board of Directors or at any special meeting of the stockholders or of the
Board of Directors if notice of such alteration, amendment, repeal or adoption
of new Bylaws be contained in the notice of such special meeting.  If the power
to adopt, amend or repeal Bylaws is conferred upon the Board of Directors by the
Certificate of Incorporation, it shall not divest or limit the power of the
stockholders to adopt, amend or repeal Bylaws.

               corporation ("Dental Management"); Dental Service and Dental
               Management, each a "Borrower" and collectively, the "Borrowers"),
               the Guarantors named herein and signatories hereto, the financial
               institutions from time to time party hereto, initially consisting
               of those financial institutions listed on Schedule 2.01(a)

     The Borrowers have applied to the Lenders for Revolving Credit Loans (such

Expenditures, as well as for other capital improvements. The proceeds of the
Revolving Credit Loans shall also be used for general working capital purposes.
The Grantors will provide Collateral in accordance with the provisions of this

jointly, willing to extend such Loans to the Borrowers subject to the terms and
conditions hereinafter set forth. Accordingly, the Borrowers, the Guarantors,

all capital expenditures (other than De Novo Capital Expenditures) incurred (or
expected to be incurred) by such person within the first six months of any
dental practice becoming an Affiliated Dental Practice, including, without
limitation, expenditures related to management information system requirements
and expenditures to upgrade the image of such Affiliated Dental Practice to the
Borrowers' standards.

<PAGE>


     "Adjusted EBITDA" shall mean, with respect to any person as of the last day
of any fiscal quarter, the sum of (i) with respect to De Novo Dental Practices
which have been operating for more than six months prior to such date of
determination, the product of (x) EBITDA of such De Novo Dental Practice for
such fiscal quarter (or, if shorter than a full fiscal quarter, the period
commencing with the six-month anniversary of such De Novo Dental Practice and
ending on the last day of such fiscal quarter) and (y) 4 plus (ii) with respect
to dental practices (other than De Novo Dental Practices) that have been
Affiliated Dental Practices for at least one full fiscal quarter (inclusive of
the fiscal quarter then ended), the product of (x) EBITDA of such Affiliated
Dental Practice for the fiscal quarter then ended and (y) 4 plus (iii) with
respect to dental practices (other than De Novo Dental Practices ) that have
been Affiliated Dental Practices for less than one full fiscal quarter prior to
such date of determination, Pro Forma EBITDA for such Affiliated Dental Practice
for the four fiscal quarter period ending on the last day of fiscal quarter
immediately preceding the date such dental practice became an Affiliated Dental
Practice plus (iv) with respect to the fiscal quarter ended September 30, 1998,
the product of (x) the aggregate amount of dividends paid by Dedicated Dental to
Dental Service during September 1998 and (y) 12, or, in the case of each fiscal
quarter thereafter, the product of (x) the aggregate amount of dividends paid by
Dedicated Dental to Dental Service during such fiscal quarter and (y) 4 plus (v)
with respect to any subsidiary that is in the Dental Insurance Business and is
not a Guarantor, the product of (x) the aggregate amount of dividends paid by
such person to a Borrower or Guarantor during the fiscal quarter then ended and
(y) 4; provided, however, that for the purposes of calculating the foregoing,
the aggregate amount of such dividends shall not exceed the applicable person's
EBITDA for the applicable period plus (vi) without duplication of amounts
determined above, the product of (x) EBITDA of the Borrowers and the Guarantors
(on a Consolidated basis) for the fiscal quarter then ended and (y) 4 minus
(vii) the product of (x) the aggregate corporate "selling, general and
administrative" expenses of the Borrowers and the Guarantors (on a Consolidated
basis) for the fiscal quarter then ended and other expenses not included in the
calculation of EBITDA of the Borrowers and the Guarantors and (y) 4 plus (viii)

Dental Insurance Business and is not a Guarantor for the fiscal quarter then
ended and (y) 4.

     "Adjusted LIBO Rate" shall mean, with respect to any Eurodollar Loan for
any Interest Period, an interest rate per annum (rounded upwards, if necessary,
to the next 1/16 of 1%) equal to the product of (i) the LIBO Rate in effect for
such Interest Period and (ii) Statutory Reserves. For purposes hereof,
"Statutory Reserves" shall mean a fraction (expressed as a decimal), the
numerator of which is the number one and the denominator of which is the number
one minus the aggregate of the maximum reserve percentages (including, without
limitation, any marginal, special, emergency, or supplemental reserves)
expressed as a decimal established by the Board with respect to Eurocurrency
Liabilities (as defined in Regulation D). Such reserve percentages shall
include, without limitation, those imposed under Regulation D. Eurodollar Loans


                                       2
<PAGE>


shall be deemed to constitute Eurocurrency Liabilities and as such shall be
deemed to be subject to such reserve requirements without benefit of or credit
for proration, exemptions or offsets which may be available from time to time to
any Lender under Regulation D. Statutory Reserves shall be adjusted
automatically on and as of the effective date of any change in any reserve
percentage.

     "Adjusted Senior Debt" shall mean, with respect to any person as of any
date of determination, the total Funded Debt of such person as of such date
minus the Subordinated Indebtedness of such person, and shall include earn-outs
which would be payable in cash based upon such person's operating performance as
at such date of determination. Earn-out liabilities with respect to the current
12-month period being measured shall be calculated by annualizing year-to-date
EBITDA (or, if not determined by reference to EBITDA, a similar performance
methodology) performance assuming EBITDA ( or similar performance methodology)
performance for the remaining months of the twelve month period being measured
will be identical to the EBITDA (or similar performance methodology) performance
of the most recently ended fiscal quarter (e.g., if there are four months
remaining in the 12-month period and the EBITDA performance was $300,000 in the
most recently ended quarter, the estimated EBITDA for the remaining four months
would be $400,000). Earn-out liabilities with respect to subsequent 12-month
periods shall be calculated by multiplying the EBITDA (or similar performance
methodology) performance of the most recently ended fiscal quarter by 4, and
discounting such payments by a factor of 8% in order to determine the present
value thereof.

     "Adjusted Total Funded Debt" shall mean, with respect to any person as of
any date of determination, the total Funded Debt of such person as of such date
and shall include earn-outs which would be payable in cash in connection with
completed Permitted Acquisitions based upon such person's operating performance
as at such date of determination; provided, however, that for purposes of
determining the Leverage Ratio, the Interest Leverage Ratio and Pro Forma
Adjusted Total Funded Debt, "Adjusted Total Funded Debt" shall not include the
Convertible Subordinated Notes. Earn-out liabilities with respect to the current
12-month period being measured shall be calculated by annualizing year-to-date
EBITDA (or, if not determined by reference to EBITDA, a similar performance
methodology) performance assuming EBITDA (or similar performance methodology)
performance for the remaining months of the twelve month period being measured
will be identical to the EBITDA (or similar performance methodology) performance
of the most recently ended fiscal quarter (e.g., if there are four months
remaining in the 12-month period and the EBITDA performance was $300,000 in the
most recently ended quarter, the estimated EBITDA for the remaining four months
would be $400,000). Earn-out liabilities with respect to subsequent 12-month
periods shall be calculated by multiplying the EBITDA (or similar performance
methodology) performance of the most recently ended fiscal quarter by 4, 


                                       3

and discounting such payments by a factor of 8% in order to determine the
present value thereof.

indirectly, controls or is controlled by or is under common control with such

and "under common control with"), as used with respect to any person, means the
possession, directly or indirectly, of the power to direct or cause the
direction of the management and policies of such person, whether through the
ownership of voting securities or by contract or otherwise.

     "Affiliated Dental Practice" shall mean a dental practice which has entered
into a Management Agreement and Shares Acquisition Agreement with any of the
Borrowers.

     "Agents" shall have the meaning assigned to such term in Article IX to this
Agreement.

     "Alternate Base Loan" shall mean a Loan based on the Alternate Base Rate in
accordance with Article II hereof.

     "Alternate Base Rate" shall mean, for any day, a rate per annum (rounded
upwards, if necessary, to the next 1/16 of 1%) equal to the greatest of (a) the
Prime Rate in effect on such day, (b) the Base CD Rate in effect on such day
plus 1%, and (c) the Federal Funds Effective Rate in effect on such day plus 1/2
of 1%. "Prime Rate" shall mean the rate of interest per annum publicly announced
from time to time by The Chase Manhattan Bank at its principal office in New
York City as its prime rate in effect at such time. "Base CD Rate" shall mean

of deposit reported as being in effect on such day (or, if such day shall not be
a Business Day, the next preceding Business Day) by the Board through the public
information telephone line of the Federal Reserve Bank of New York (which rate
will, under the current practices of the Board, be published in Federal Reserve
Statistical Release H.15(519) during the week following such day), or, if such


                                       4
<PAGE>


rate shall not be so reported on such day or such next preceding Business Day,

deposit of major money center banks in New York City received at approximately

Business Day, on the next preceding Business Day) by the Administrative Agent
from three New York City negotiable certificate of deposit dealers of recognized
standing selected by it. "Statutory Reserves" shall mean a fraction (expressed
as a decimal), the numerator of which is the number one and the denominator of

Administrative Agent is subject for new negotiable nonpersonal time deposits in
dollars of over $100,000 with maturities approximately equal to three months.
Statutory Reserves shall be adjusted automatically on and as of the effective
date of any change in any reserve percentage. "Assessment Rate" shall mean, for
any day, the annual assessment rate (net of refunds and rounded upwards, if
necessary, to the next 1/16 of 1%) estimated by the Administrative Agent (in
good faith, but in no event in excess of statutory or regulatory maximums) to be
payable by the Administrative Agent to the Federal Deposit Insurance Corporation
(or any successor) for insurance by such Corporation (or such successor) of time
deposits made in dollars at the Administrative Agent's domestic offices during
the current calendar year. "Federal Funds Effective Rate" shall mean, for any
day, the weighted average of the rates on overnight Federal funds transactions
with members of the Federal Reserve System arranged by Federal funds brokers, as

York, or, if such rate is not so published for any day which is a Business Day,
the average of the quotations for the day of such transactions received by the
Administrative Agent from three Federal funds brokers of recognized standing
selected by it. If for any reason the Administrative Agent shall have determined
(which determination shall be conclusive absent manifest error) that it is
unable to ascertain the Base CD Rate or the Federal Funds Effective Rate, or
both, for any reason, including, the inability or failure of the Administrative
Agent to obtain sufficient quotations in accordance with the terms hereof, the
Alternate Base Rate shall be determined without regard to clause (b) or (c), or
both, of the first sentence of this definition, as appropriate, until the
circumstances giving rise to such inability no longer exist. Any change in the
Alternate Base Rate due to a change in the Prime Rate, the Base CD Rate or the
Federal Funds Effective Rate shall be effective on the effective date of such
change in the Prime Rate, the Base CD Rate or the Federal Funds Effective Rate,
respectively.

     "Applicable Lending Office" shall mean, with respect to each Lender, such
Lender's Domestic Lending Office in the case of an Alternate Base Loan and such
Lender's Eurodollar Lending Office in the case of a Eurodollar Loan.

II.  THE LOANS

          SECTION II.1. Revolving Credit Commitments and Term Loan. (a) Subject
to the terms and conditions and relying upon the representations and warranties
herein set forth, each Lender, severally and not jointly, agrees to make
Revolving Credit Loans to the Borrowers, at any time and from time to time from
the date hereof to the earlier of (i) the Revolving Credit Termination Date and
(ii) the Conversion Date, in an aggregate principal amount at any time
outstanding not to exceed the amount of such Lender's Revolving Credit
Commitment set forth opposite its name in Schedule 2.01(a) annexed hereto, as
such Revolving Credit Commitment may be reduced from time to time in accordance
with the provisions of this Agreement. Notwithstanding the foregoing, the
aggregate principal amount of Revolving Credit Loans outstanding at any time to
the Borrowers shall not exceed the Total Revolving Credit Commitment (as such
amount may be reduced pursuant to this Agreement including, without limitation,
Section 2.07 hereof) minus the Letter of Credit Usage at such time (such Letter
of Credit Usage not to exceed $1,000,000 at any time).

          Subject to the foregoing and within the foregoing limits, the
Borrowers may borrow, repay (or, subject to the provisions of Section 2.09
hereof, prepay) and reborrow Revolving Credit Loans, on and after the date
hereof and prior to the earlier of (i) the Revolving Credit Termination Date and
(ii) the Conversion Date, subject to the terms, provisions and limitations set
forth herein, including, without limitation, the requirement that no Revolving
Credit Loan shall be made hereunder after giving effect thereto the sum of the
aggregate principal amount of the Revolving Credit Loans outstanding hereunder
plus the Letter of Credit Usage would exceed the Total Revolving Credit
Commitment (as such amount may be reduced pursuant to the provisions of this
Agreement).

<PAGE>

          (b  Subject to the terms and conditions of this Agreement, including,
without limitation, that no Default or Event of Default shall then exist, on
September 30, 2001 (the "Conversion Date"), then the unpaid principal amount of
Revolving Credit Loans shall be converted into a Term Loan (the "Term Loan")
from the Lenders.

          SECTION II.2.  Loans. (a) The Revolving Credit Loans made by the
Lenders on any date shall be in integral multiples of $100,000 (except that the
foregoing limitation shall not be applicable to the extent that the proceeds of
such Loans are requested to be disbursed to the Borrowers' controlled
disbursement account maintained with the Administrative Agent); provided,
however, that the Eurodollar Loans made on any date shall be in a minimum
aggregate principal amount equal to the product of $500,000 times the number of
Lenders on such date.

          (b  Loans shall be made ratably by the Lenders in accordance with
their respective Revolving Credit Commitments; provided, however, that the
failure of any Lender to make any Loan shall not in itself relieve any other
Lender of its obligation to lend hereunder. The initial Revolving Credit Loans
shall be made by the Lenders against delivery of Revolving Credit Notes, payable
to the order of the Lenders, as referred to in Section 2.04 hereof. On the
Conversion Date, the Term Loans to be made by the Lenders shall be made against
delivery of Term Notes payable to the order of the Lenders, as referred to in
Section 2.04 hereof.

          (c  Each Loan shall be either an Alternate Base Loan or a Eurodollar
Loan as the Borrowers may request pursuant to Section 2.03 hereof. Each Lender
may fulfill its obligations under this Agreement by causing its Applicable
Lending Office to make such Loan; provided, however, that the exercise of such
option shall not affect the obligation of the Borrowers to repay such Loan in
accordance with the terms of the applicable Note. Not more than five (5)
Eurodollar Loans may be outstanding at any one time.

          (d  Subject to the provisions of paragraph (e) below, each Lender
shall make its Revolving Credit Loans on the proposed dates thereof by paying
the amount required to the Administrative Agent in Walnut Creek, California in
immediately available funds not later than 12:00 noon, Los Angeles, California
time, and the Administrative Agent shall as soon as practicable, but in no event
later than 3:00 P.M., Los Angeles, California time, credit the amounts so
received to the general deposit account of the Borrowers with the Administrative
Agent in immediately available funds or, if Loans are not to be made on such
date because any condition precedent to a borrowing herein specified is not met,
return the amounts so received to the respective Lenders.

          (e  The Borrowers shall have the right at any time upon prior
irrevocable written, telex or facsimile notice (promptly confirmed in writing)
to the Administrative Agent given in the manner and at the times specified in
Section 2.03 with

          Loans comprising the conversion or continuation, and in the case of a
          conversion or continuation of fewer than all the Loans, the aggregate
          principal amount of Loans converted or continued shall not be less
          than $100,000 in the case of Alternate Base Loans (except that the
          foregoing limitation shall not be applicable to the extent that the
          proceeds of such Loans are requested to the disbursed to the
          Borrowers' controlled disbursement account maintained with the
          Administrative Agent) or $500,000 times the number of Lenders on such
          date in the case of Eurodollar Loans, and, in any event shall be an
          integral multiple of $100,000;

               (ii  accrued interest on a Eurodollar Loan (or portion thereof)
          being converted shall be paid by the Borrowers at the time of
          conversion;

               (iii  if any Eurodollar Loan is converted at any time other than
          the end of an Interest Period applicable thereto, the Borrowers shall
          make such payments associated therewith as are required pursuant to
          Section 2.12;

               (iv  any portion of a Revolving Credit Eurodollar Loan which is
          subject to an Interest Period ending on a date that is less than one
          (1) month prior to the Revolving Credit Termination Date may not be
          converted into, or continued as, a Eurodollar Loan and shall be
          automatically converted at the end of such Interest Period into an
          Alternate Base Loan;

               (v  any portion of a Term Eurodollar Loan required to be paid on
          any Repayment Date occurring less than one (1) month after the end of
          the then current Interest Period applicable to such Loan, may not be
          converted into, or continued as, a Term Eurodollar Loan and shall be
          automatically converted at the end of such Interest Period into a Term
          Alternate Base Loan; and

          continuing.

          The Interest Period applicable to any Eurodollar Loan resulting from a
conversion shall be specified by the Borrowers in the irrevocable notice of
conversion delivered pursuant to this Section; provided, however, that if no
such Interest Period shall be specified, the Borrowers shall be deemed to have
selected an Interest Period of one (1) months' duration; and, provided, further,
that no such Interest Period may be for more than one (1) month for the period
commencing on the Closing Date and earlier to occur of (x) the 120th day
following the Closing Date and (y) the completion to the satisfaction of the
Syndication Agent of the syndication of the Total Revolving Credit Commitment
and the Loans and other Credits thereunder. If the Borrowers shall not have
given timely notice to continue any Eurodollar Loan into a subsequent Interest
Period (and shall not otherwise have given notice to convert such Loan), such
Loan (unless repaid or required to be repaid pursuant to the terms hereof) shall
automatically be converted into an Alternate Base Loan. The Administrative Agent
shall promptly advise the Lenders of any notice given pursuant to this Section
and of each Lender's portion of the continuation or conversion hereunder.

          SECTION II.3.  Notice of Loans. The Borrowers shall, through a
Responsible Officer of any of the Borrowers, give the Administrative Agent
irrevocable written, telex or facsimile notice (promptly confirmed in writing)
of each borrowing (including, without limitation, a conversion as permitted by
Section 2.02(e) hereof) not later than 11:00 A.M., Los Angeles, California time,
(i) three (3) Business Days before a proposed Eurodollar Loan borrowing or
conversion and (ii) one Business Day before an Alternate Base Loan borrowing or
conversion (except that no such confirmation will be required, unless requested
by the Administrative Agent, to the extent that the proceeds of such borrowing
are requested to be disbursed to Borrowers' controlled disbursement account
maintained with the Administrative Agent). Such notice shall specify (w) whether
the Loans then being requested are to be Alternate Base Loans or Eurodollar
Loans, it being agreed that all Loans made on the Closing Date shall be
Alternate Base Loans, (x) the date of such borrowing (which shall be a Business
Day) and amount thereof and (y) if such Loans are to be Eurodollar Loans, the
Interest Period with respect thereto. If no election as to the type of Loan is
specified in any such notice, all such Loans shall be Alternate Base Loans. If
no Interest Period with respect to any Eurodollar Loan is specified in any such
notice, then an Interest Period of one (1) month's duration shall be deemed to
have been selected; provided, however, that no such Interest Period may be for
more than one (1) month for the period commencing on the Closing Date and ending
on the earlier to occur of (x) the 120th day following the Closing Date and (y)
the completion to the satisfaction of the Syndication Agent of the syndication
of the Total Revolving Credit Commitment and the Loans and other Credits
thereunder. The Administrative Agent shall promptly advise the Lenders

                                       30
<PAGE>

of any notice given pursuant to this Section 2.03 and of each Lender's portion
of the requested borrowing.

          SECTION II.4.  Notes; Repayment of Loans. (a) All Revolving Credit
Loans made by a Lender to the Borrowers shall be evidenced by a single Revolving
Credit Note, duly executed on behalf of the Borrowers, dated the Closing Date,
in substantially the form of Exhibit B annexed hereto, delivered and payable to
such Lender in a principal amount equal to its Revolving Credit Commitment on
such date. The outstanding balance of each Revolving Credit Loan, as evidenced
by any such Revolving Credit Note, shall mature and be due and payable on the
Revolving Credit Termination Date if such date occurs earlier than the
Conversion Date or, subject to the terms and conditions of this Agreement,
including, without limitation, that no Default or Event of Default shall then
exist, shall be converted to a Term Loan on the Conversion Date. The Term Loan
made by a Lender on the Conversion Date shall be evidenced by a single Term
Note, duly executed on behalf of the Borrowers, dated the Conversion Date, in
substantially the form of Exhibit A annexed hereto, delivered and payable to
such Lender in a principal amount equal to its pro rata share (based on its
Revolving Credit Commitment) of the Revolving Credit Loans being converted on
such date; provided, however, that the failure of the Borrowers to deliver Term
Notes pursuant to the provisions of this Section shall not affect the liability
of the Borrowers to repay the amount of Revolving Credit Loans being converted.

          (b  Each Revolving Credit Note shall bear interest from its date on
the outstanding principal balance thereof, as provided in Section 2.05 hereof.

          (c  The aggregate principal amount of the Term Loan, as evidenced by
the Term Notes, shall be payable in sixteen (16) consecutive quarterly
installments on the first Business Day of each October, January, April and July
of each year (the date of each such installment, a "Repayment Date"), commencing
with the first Business Day of the first full fiscal quarter succeeding the
Conversion Date, in the amount set forth in the next sentence, and such payments
shall be distributed ratably among the Lenders in accordance with their pro rata
share of such Term Loan. Payments of principal on each Repayment Date shall be
in equal amounts calculated on an amortization schedule which assumes a maturity
date ending four (4) years subsequent to the Conversion Date and which will be
confirmed in writing to the Borrowers by the Administrative Agent; provided,
however, that the final installment under such Term Note shall be in the amount
of the unpaid principal balance of such Term Note and shall be payable on the
Final Maturity Date.

          To the extent not previously paid, the Term Loan shall be due and
payable on the Final Maturity Date. Each Term Note shall bear interest from its
date on the outstanding principal balance thereof, as provided in Section 2.05.
All principal payments in respect of the Term Loan shall be accompanied by
accrued interest on the principal amount being repaid to the date of payment. No
scheduled payment of

                                       31
<PAGE>

principal in respect of the Term Loan shall be made to the extent that a lesser
principal payment would result in the payment in full of the outstanding amount
of the Term Loan, and such lesser amount is paid.

          (d  Each Lender, or the Administrative Agent on its behalf, shall, and
is hereby authorized by the Borrowers to, endorse on the schedule attached to
the Term Note or Revolving Credit Note, as applicable, of such Lender (or on a
continuation of such schedule attached to such Note and made a part thereof) an
appropriate notation evidencing the date and amount of each Loan to the
Borrowers from such Lender, as well as the date and amount of each payment and
prepayment with respect thereto; provided, however, that the failure of any
person to make such a notation on a Note shall not affect any obligations of the
Borrowers under such Note. Any such notation shall be conclusive and binding as
to the date and amount of such Loan or portion thereof, or payment or prepayment
of principal or interest thereon, absent manifest error.

          (e Each of the Borrowers shall be jointly and severally liable with
the other Borrower(s) for the Obligations, and each of the Obligations shall be
secured by all of the Collateral. Each of the Borrowers acknowledges that it is
a co-borrower hereunder and is jointly and severally liable under this Agreement
and the other Loan Documents. All Credits extended to any of the Borrowers or
requested by any of the Borrowers shall be deemed to be Credits extended for
each of the Borrowers, and each of the Borrowers hereby authorizes each other of
the Borrowers to effectuate Credits on its behalf. Notwithstanding anything to
the contrary contained in this Agreement or any of the other Loan Documents, the
Agents and the Lenders shall be entitled to rely upon any request, notice or
other communication received by them from any of the Borrowers on behalf of all
Borrowers, and shall be entitled to treat their giving of any notice hereunder
to any of the Borrowers as notice to each and all Borrowers.

          Each of the Borrowers agrees that the joint and several liability of
the Borrowers provided for in this subsection (e) shall not be impaired or
affected by any modification, supplement, extension or amendment or any contract
or agreement to which the other Borrower(s) may hereafter agree (other than an
agreement signed by the Administrative Agent and the Lenders specifically
releasing such liability), nor by any delay, extension of time, renewal,
compromise or other indulgence granted by the Administrative Agent or any Lender
with respect to any of the Obligations, nor by any other agreements or
arrangements whatsoever with the other Borrower(s) or with any other person,
each of the Borrowers hereby waiving all notice of such delay, extension,
release, substitution, renewal, compromise or other indulgence, and hereby
consenting to be bound thereby as fully and effectually as if it had expressly
agreed thereto in advance. The liability of each of the Borrowers is direct and
unconditional as to all of the Obligations, and may be enforced without
requiring the Administrative Agent or any Lender first to resort to any other
right, remedy or security. Each of the Borrowers hereby expressly waives
promptness, diligence, notice of acceptance and any other

                                       32
<PAGE>

notice with respect to any of the Obligations, the Notes, this Agreement or any
other Loan Document and any requirement that the Administrative Agent or any
Lender protect, secure, perfect or insure any Lien or any property subject
thereto or exhaust any right or take any action against any of the Borrowers or
any other person or any collateral.

          Each of the Borrowers hereby irrevocably waives and releases each
other of the Borrowers from all "claims" (as defined in Section 101(5) of the
Bankruptcy Code) to which such Borrowers are or would be entitled by virtue of
the provisions of the first paragraph of this subsection (e) or the performance
of such Borrower's obligations thereunder including, without limitation, any
right of subrogation (whether contractual, under Section 509 of the Bankruptcy
Code or otherwise), reimbursement, contribution, exoneration or similar right,
or indemnity, or any right of recourse to security for any of the Obligations.

          SECTION II.5. Interest on Loans. (a) Subject to the provisions of
Section 2.05(c) and Section 2.08 hereof, each Alternate Base Loan shall bear
interest at a rate per annum equal to the Alternate Base Rate plus the
applicable Interest Margin.

          (b  Subject to the provisions of Section 2.05(c) and Section 2.08
hereof, each Eurodollar Loan shall bear interest at a rate per annum equal to
the Adjusted LIBO Rate plus the applicable Interest Margin.

          (c  Interest on each Loan shall be payable in arrears on each
applicable Interest Payment Date, the Conversion Date, the Revolving Credit
Termination Date and on the Final Maturity Date, as applicable. Interest on each
Alternate Base Loan and Eurodollar Loan shall be computed based on the number of
days elapsed in a year of 360 days. The Administrative Agent shall determine
each interest rate applicable to the Loans and shall promptly advise the
Borrowers and the Lenders of the interest rate so determined.

          SECTION II.6. Fees. The Borrowers shall pay each Lender, through the
Administrative Agent, (i) on the first Business Day of each October, January,
April and July, commencing October 1, 1998, (ii) on the date of any reduction of
the Revolving Credit Commitments pursuant to this Agreement including, without
limitation, Section 2.07 hereof and (iii) on the earlier to occur of (x) the
Revolving Credit Termination Date and (y) the Conversion Date, in immediately
available funds, a commitment fee (the "Revolving Credit Commitment Fee") equal
to the Commitment Fee Percentage on the average daily unused (treating Letter of
Credit Usage as usage) amount of the Revolving Credit Commitment of such Lender,
during the quarter (or shorter period commencing with the date hereof or ending
with the Revolving Credit Termination Date) ending on such date. The Revolving
Credit Commitment Fee due to each Lender under this Section 2.06 shall commence
to accrue on the date hereof and

                                       33
<PAGE>

cease to accrue on the earliest of (i) the Revolving Credit Termination Date,
(ii) the termination of the Revolving Credit Commitment of such Lender pursuant
to this Agreement including, without limitation, pursuant to Section 2.07 hereof
and (iii) the Conversion Date. The Revolving Credit Commitment Fee shall be
calculated on the basis of the actual number of days elapsed in a year of 360
days.

          SECTION II.7.  Termination and Reduction of Revolving Credit
Commitments. (a) Upon at least two (2) Business Days' prior irrevocable written
notice (or facsimile notice promptly confirmed in writing) to the Administrative
Agent, the Borrowers may at any time in whole permanently terminate, or from
time to time in part permanently reduce, the Total Revolving Credit Commitment,
ratably among the Lenders in accordance with the amounts of their Revolving
Credit Commitments; provided, however, that the Total Revolving Credit
Commitment shall not be reduced at any time to an amount less than the Revolving
Credit Loans outstanding under the Revolving Credit Commitments and the Letter
of Credit Usage at such time. Each partial reduction of the Total Revolving
Credit Commitment shall be in a minimum of $100,000 or an integral multiple of
$100,000.

          (b  Simultaneously with any termination or reduction of the Total
Revolving Credit Commitment pursuant to paragraph (a) of this Section 2.07, the
Borrowers shall pay to each Lender, through the Administrative Agent, the
Revolving Credit Commitment Fee due and owing through and including the date of
such termination or reduction on the amount of the Revolving Credit Commitment
of such Lender so terminated or reduced.

          (c  The Revolving Credit Commitment of each Lender shall automatically
and permanently terminate on the earlier of (i) the Revolving Credit Termination
Date and (ii) the Conversion Date, and all Revolving Credit Loans still
outstanding on such date shall be due and payable in full together with accrued
interest thereon on the Revolving Credit Termination Date, if such date occurs
earlier than the Conversion Date, or, subject to the terms and conditions of
this Agreement, including, without limitation, that no Default or Event of
Default shall then exist, shall be converted to a Term Loan on the Conversion
Date.

          SECTION II.8.  Interest on Overdue Amounts; Alternate Rate of
Interest. (a) If the Borrowers shall default in the payment of the principal of
or interest on any Loan or any other amount becoming due hereunder, by
acceleration or otherwise, the Borrowers shall on demand from time to time pay
interest, to the extent permitted by law, on all Obligations outstanding up to
the date of actual payment of such defaulted amount (after as well as before
judgment) at a rate per annum equal to two percent (2%) in excess of the rates
otherwise applicable thereto.

          (b  In the event, and on each occasion, that on the day two (2)
Business Days prior to the commencement of any Interest Period for a Eurodollar

                                       34
<PAGE>

Loan the Administrative Agent shall have determined that dollar deposits in the
amount of each Eurodollar Loan are not generally available in the London
interbank market, or that the rate at which dollar deposits are being offered
will not reflect adequately and fairly the cost to any Lender of making or
maintaining such Eurodollar Loan during such Interest Period, or that reasonable
means do not exist for ascertaining the Adjusted LIBO Rate, the Administrative
Agent shall as soon as practicable thereafter give written notice (or facsimile
notice promptly confirmed in writing) of such determination to the Borrowers and
the Lenders, and any request by the Borrowers for the making of a Eurodollar
Loan pursuant to Section 2.03 hereof or conversion or continuation of any Loan
into a Eurodollar Loan pursuant to Section 2.02 hereof shall, until the
circumstances giving rise to such notice no longer exist, be deemed to be a
request for an Alternate Base Loan. Each determination by the Administrative
Agent made hereunder shall be conclusive absent manifest error.

          SECTION II.9. Prepayment of Loans. (a) Subject to the terms and
conditions contained in this Section 2.09 and elsewhere in this Agreement, the
Borrowers shall have the right to prepay any Loan at any time in whole or from
time to time in part without penalty (except as otherwise provided for herein);
provided, however, that each such partial prepayment of a Loan shall be in an
integral multiple of $100,000.

          (b  On the date of any termination or reduction of the Total Revolving
Credit Commitment pursuant to Section 2.07(a) hereof or elsewhere in this
Agreement, the Borrowers shall pay or prepay so much of the Revolving Credit
Loans as shall be necessary in order that the aggregate principal amount of the
Revolving Credit Loans plus the Letter of Credit Usage outstanding will not
exceed the Total Revolving Credit Commitment following such termination or
reduction. Any prepayments required by this paragraph (b) shall be applied to
outstanding Revolving Credit Alternate Base Loans up to the full amount thereof
before they are applied to outstanding Revolving Credit Eurodollar Loans;
provided, however, that the Borrowers shall not be required to make any
prepayment of any Eurodollar Loan pursuant to this Section until the last day of
the Interest Period with respect thereto so long as an amount equal to such
prepayment is deposited by the Borrowers in a cash collateral account with the
Administrative Agent to be held in such account on terms satisfactory to the
Administrative Agent.

          (c  The Borrowers shall make prepayments of the Revolving Credit Loans
from time to time such that the outstanding principal balance of such Revolving
Credit Loans plus the Letter of Credit Usage does not exceed the Total Revolving
Credit Commitment. Any prepayments required by this paragraph (c) shall be
applied to outstanding Revolving Credit Alternate Base Loans up to the full
amount thereof before they are applied to outstanding Revolving Credit
Eurodollar Loans; provided, however, that the Borrowers shall not be required to
make any prepayment of any Eurodollar Loan pursuant to this Section until the
last day of the Interest Period with respect thereto so long as an amount equal
to such prepayment is deposited by the

                                       35
<PAGE>

Borrowers in a cash collateral account with the Administrative Agent to be held
in such account on terms satisfactory to the Administrative Agent.

          (d  Within three (3) Business Days of (i) the sale or other
disposition of any assets of any Loan Party (excluding (x) sales of assets in
the ordinary course of business, and (y) subject to Section 6.02 hereof, sales
of worn-out or obsolete assets but only to the extent that the net proceeds
realized are applied within three (3) Business Days of any sale or other
disposition to purchase other assets and pending such application or prepayment
all such net proceeds shall be maintained in a cash collateral account with the
Administrative Agent on terms and conditions acceptable to the Administrative
Agent) or of the capital stock of any of the Borrowers (subject to Section 7.05
hereof), or (ii) the consummation of the issuance of any debt securities of any
of the Loan Parties, the Borrowers shall make a mandatory prepayment of the
Loans in an amount equal to 100% of the proceeds received (net of taxes due and
any reasonable expenses of sale), which proceeds shall be applied as set forth
in paragraph (g) below. Nothing contained in this paragraph (d) shall be or be
deemed to be a consent to the sale of any assets or stock or the issuance of any
stock or debt securities.

          (e  Within 105 days of the end of each Fiscal Year of the Borrowers,
commencing with the Fiscal Year ending December 31, 2001, the Borrowers shall
make a mandatory prepayment of the Loans in an amount equal to the Mandatory
Prepayment, if any, of the Borrowers and their subsidiaries for the Fiscal Year
then ended, such prepayment to be applied as set forth in paragraph (g) below.

          (f(i  Except as provided in clause (ii) below, promptly and in any
event not more than three (3) Business Days following the receipt by the
Administrative Agent or any of the Borrowers or any subsidiary of any of the
Borrowers of any net proceeds of (x) any casualty insurance required to be
maintained pursuant to Section 6.03 hereof on account of each separate loss,
damage or injury (each, a "Casualty Event") in excess of $200,000 (or, if there
shall be continuing a Default or an Event of Default, of the full amount of net
proceeds) to any asset of such Borrowers or such subsidiary (including, without
limitation, any Collateral), or (y) any business interruption insurance required
to be maintained pursuant to Section 6.03 hereof on account of any business
interruption event (each, a "BI Event") in excess of $200,000 (or, if there
shall be continuing a Default or Event of Default, of the full amount of net
proceeds), such Borrowers or subsidiary shall notify the Administrative Agent of
such receipt in writing or by telephone promptly confirmed in writing, and not
later than three (3) Business Days following receipt by the Administrative Agent
or such Borrowers or subsidiary of any such proceeds, there shall become due and
payable a prepayment of the Loans in an amount equal to 100% of such proceeds.
Prepayments from such net proceeds shall be applied as set forth in paragraph
(g) below.

                                       36
<PAGE>

          (ii   In the case of the receipt of net proceeds described in clause
(i) above with respect to a Casualty Event or BI Event, the Borrowers may elect,
by written notice delivered to the Administrative Agent not later than the day
on which a prepayment would otherwise be required under clause (i), (x) in the
case of proceeds received with respect to a BI Event, to use such proceeds in
the ordinary course of such Borrower's business and (y) in the case of proceeds
received with respect to any Casualty Event, to apply all or a portion of such
net proceeds for the purpose of replacing, repairing, restoring or rebuilding
(referred to herein as a "Rebuilding") the relevant tangible property, and, in
any such event, any required prepayment under clause (i) above shall be reduced
dollar for dollar by the amount of such election under clause (x) or clause (y)
of this sentence. An election under this clause (ii) shall not be effective
unless: (x) at the time of such election there is continuing no Default or Event
of Default; (y) the Borrowers shall have certified to the Administrative Agent
that: (i) the net proceeds of the insurance adjustment with respect to a
Casualty Event, together with other funds available to the Borrowers shall be
sufficient to complete such Rebuilding in accordance with all applicable laws,
regulations and ordinances; and (ii) no Default or Event of Default has arisen
or will arise as a result of such BI Event, Casualty Event or Rebuilding; and
(z) if the amount of net proceeds in question exceeds $1,000,000, the Borrowers
shall have obtained the written consent of the Required Lenders to such
election.

          (iii  In the event of an election under clause (ii) above, pending
application of the net proceeds to business operations with respect to a BI
Event or to Rebuilding with respect to a Casualty Event, the Borrowers shall not
later than the time at which prepayment would have been, in the absence of such
election, required under clause (i) above, apply such net proceeds to the
prepayment of the outstanding principal balance, if any, of the Revolving Credit
Loans (not in permanent reduction of the Revolving Credit Commitment), and
deposit (the "Special Deposit") with the Administrative Agent, the balance, if
any, of such net proceeds remaining after such application, pursuant to
agreements in form, scope and substance reasonably satisfactory to the
Administrative Agent. The Special Deposit, together with all earnings on such
Special Deposit, shall be available to the Borrowers solely for the applicable
Rebuilding or ordinary course business operations, as the case may be; provided,
however, that at such time as a Default or Event of Default shall occur, the
balance of the Special Deposit and earnings thereon may be applied by the
Administrative Agent to repay the Obligations in such order as the
Administrative Agent shall elect. The Administrative Agent shall be entitled to
require proof, as a condition to the making of any withdrawal from the Special
Deposit, that the proceeds of such withdrawal are being applied for the purposes
permitted hereunder.

          (iv  Notwithstanding anything to the contrary contained in this
paragraph (f), on the date three (3) Business Days following the receipt by the
Administrative Agent or any Borrower of any net proceeds of any insurance
referred to

                                       37
<PAGE>

in Section 6.16 hereof, there shall become due and payable a prepayment of
principal in respect of the Obligations in an amount equal to 100% of such net
proceeds. All prepayments made pursuant to this clause (iv) shall be applied in
the manner set forth in paragraph (g) below.

          (g  When making a prepayment, whether mandatory or otherwise, pursuant
to paragraph (a), (b), (c), (d), (e) or (f) above, the Borrowers shall furnish
to the Administrative Agent, not later than 11:00 A.M. (Los Angeles, California
time) (i) three (3) Business Days prior to the date of such prepayment of
Alternate Base Loans and (ii) five (5) Business Days prior to the date of such
prepayment of Eurodollar Loans, written, telex or facsimile notice (promptly
confirmed in writing) of prepayment which shall specify the prepayment date and
the principal amount of each Loan (or portion thereof) to be prepaid, which
notice shall be irrevocable and shall commit the Borrowers to prepay such Loan
by the amount stated therein on the date stated therein. All prepayments shall
be accompanied by accrued interest on the principal amount being prepaid to the
date of prepayment. Prepayments made pursuant to paragraph (d), (e) or (f) above
shall be applied as follows: (A) prior to the Conversion Date, to outstanding
Revolving Credit Alternate Base Loans up to the full amount thereof and then to
Revolving Credit Eurodollar Loans up to the full amount thereof, and (B)
following the Conversion Date, with respect to the Term Loan, to outstanding
Term Alternate Base Loans pro rata over the remaining Repayment Dates up to the
full amount thereof and then to outstanding Term Eurodollar Loans pro rata over
the remaining Repayment Dates up to the full amount thereof; provided, however,
that if at the time of the making of any prepayment in accordance with clause
(A), there are undrawn Letters of Credit outstanding, then in the discretion of
the Administrative Agent, all or any portion of any such prepayment (not to
exceed an amount equal to the aggregate undrawn amount of all such outstanding
Letters of Credit) remaining after payment in full of the Revolving Credit Loans
shall be deposited by the Borrowers in a cash collateral account to be held by
the Administrative Agent for its own benefit and for the benefit of the Lenders
for application by the Administrative Agent to the payment of any drawing made
under any such Letters of Credit; provided, however, that the Borrowers shall
not be required to make any prepayment of any Term or Revolving Credit
Eurodollar Loan required pursuant to this Section 2.09(g) until the last day of
the Interest Period with respect thereto so long as an amount equal to such
prepayment is deposited by the Borrowers into a cash collateral account with the
Administrative Agent to be held in such account pursuant to terms satisfactory
to the Administrative Agent.

          (h  All prepayments under this Section 2.09 shall be subject to
Section 2.12 hereof.

          (i  Except as otherwise expressly provided in this Section 2.09,
payments with respect to any paragraph of this Section 2.09 are in addition to
payments made or required to be made under any other paragraph of this Section
2.09.

<PAGE>

          (j  All prepayments of the Term Loan under this Section 2.09 shall be
applied pro rata over the remaining Repayment Dates. The amount of the Term Loan
prepaid may not be reborrowed.

          SECTION II.10.  Reserve Requirements; Change in Circumstances. (a
Notwithstanding any other provision herein, if after the date of this Agreement
(or in the case of any assignee of any Lender, the date of assignment) any
change in applicable law or regulation or in the interpretation or
administration thereof by any governmental authority charged with the
interpretation or administration thereof (whether or not having the force of
law), or any change in GAAP or regulatory accounting principles applicable to
the Administrative Agent or any Lender, shall: (i) subject the Administrative
Agent or any Lender (which shall for the purpose of this Section 2.10 include
any assignee or lending office of the Administrative Agent or any Lender) to any
charge, fee, deduction or withholding of any kind or to any tax with respect to
any amount paid or to be paid to either the Administrative Agent or any Lender
with respect to any Eurodollar Loans made by such Lender to the Borrowers or
with respect to the obligations of any Lender under Sections 2.17 through 2.20
hereof or under any Letter of Credit (other than (x) taxes imposed on the
overall net income of the Administrative Agent or such Lender and (y) franchise
taxes imposed on the Administrative Agent or such Lender, in either case by the
jurisdiction in which such Lender or the Administrative Agent has its principal
office or its lending office with respect to such Eurodollar Loan or any
political subdivision or taxing authority of either thereof); (ii) change the
basis of taxation of payments to any Lender or the Administrative Agent of the
principal of or interest on any Eurodollar Loan or any other fees or amounts
payable with respect to any Letter of Credit or otherwise hereunder (other than
taxes imposed on the overall net income of such Lender or the Administrative
Agent by the jurisdiction in which such Lender or the Administrative Agent has
its principal office or by any political subdivision or taxing authority
therein); (iii) impose, modify or deem applicable any reserve, special deposit
or similar requirement against assets of, deposits with or for the account of,
or loans or loan commitments extended by, or Letters of Credit issued and
maintained by such Lender; or (iv) impose on any Lender or, with respect to
Eurodollar Loans, the London interbank market, any other condition affecting
this Agreement, Letters of Credit issued and maintained by or Eurodollar Loans
made by such Lender; and the result of any of the foregoing shall be to increase
the cost to any such Lender of making or maintaining any Eurodollar Loan or
Letter of Credit, or to reduce the amount of any payment (whether of principal,
interest, fee, compensation or otherwise) receivable by such Lender or to
require such Lender to make any payment in respect of any Eurodollar Loan or
Letter of Credit, then the Borrowers shall pay to such Lender or the
Administrative Agent, as the case may be, upon such Lender's or the
Administrative Agent's demand, such additional amount or amounts as will
compensate such Lender or the Administrative Agent for such additional costs or
reduction. The Administrative Agent and each Lender agree to give notice to the
Borrowers of any such change in law, regulation,

                                       39

interpretation or administration with reasonable promptness after becoming
actually aware thereof and of the applicability thereof to the Transactions.
Notwithstanding anything contained herein to the contrary, nothing in clause (i)
or (ii) of this Section 2.10(a) shall be deemed to (x) permit the Administrative
Agent or any Lender to recover any amount thereunder which would not be
recoverable under Section 2.16 hereof or (y) require the Borrowers to make any
payment of any amount to the extent that such payment would duplicate any
payment made by the Borrowers pursuant to Section 2.16 hereof.

          (b  If at any time and from time to time after the date of this
Agreement, any Lender shall determine that the adoption of any applicable law,
rule, regulation or guideline regarding capital adequacy, or any change in any
applicable law, rule, regulation or guideline regarding capital adequacy,
including, without limitation, the July 1988 report of the Basle Committee on
Banking Regulations and Supervisory Practices entitled "International
Convergence of Capital Measurement and Capital Standards", or any change in the
interpretation or administration of any thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by such Lender (or its lending office)
with any request or directive regarding capital adequacy (whether or not having
the force of law) of any such authority, central bank or comparable agency, has
or will have the effect of reducing the rate of return on such Lender's capital
or on the capital of such Lender's holding company, if any, as a consequence of
its obligations hereunder to a level below that which such Lender could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's policies and the policies of such Lender's holding company with
respect to capital adequacy), then from time to time the Borrowers shall pay to
such Lender such additional amount or amounts as will compensate such Lender for
such reduction. Each Lender agrees to give notice to the Borrowers of any
adoption of, change in, or change in interpretation or administration of, any
such law, rule, regulation or guideline with reasonable promptness after
becoming actually aware thereof and of the applicability thereof to the
Transactions.

          (c  A statement of any Lender or the Administrative Agent setting
forth such amount or amounts, supported by calculations in reasonable detail, as
shall be necessary to compensate such Lender (or the Administrative Agent) as
specified in paragraphs (a) and (b) above shall be delivered to the Borrowers
and shall be conclusive absent manifest error. The Borrowers shall pay such
Lender or the Administrative Agent, as the case may be, the amount shown as due
on any such statement within ten (10) days after its receipt of the same.

          (d  Failure on the part of any Lender or the Administrative Agent to
demand compensation for any increased costs, reduction in amounts received or
receivable with respect to any Interest Period or any Letter of Credit or
reduction in the rate of return earned on such Lender's capital, shall not
constitute a waiver of such

                                       40
<PAGE>

Lender's or the Administrative Agent's rights to demand compensation for any
increased costs or reduction in amounts received or receivable or reduction in
rate of return in such Interest Period or in any other Interest Period or with
respect to such Letter of Credit. The protection under this Section 2.10 shall
be available to each Lender and the Administrative Agent regardless of any
possible contention of the invalidity or inapplicability of any law, regulation
or other condition which shall give rise to any demand by such Lender or the
Administrative Agent for compensation.

          (e  Any Lender claiming any additional amounts payable pursuant to
this Section 2.10 agrees to use reasonable efforts (consistent with legal and
regulatory restrictions) to designate a different Applicable Lending Office if
the making of such a designation would avoid the need for, or reduce the amount
of, any such additional amounts and would not, in the reasonable judgment of
such Lender, be otherwise disadvantageous to such Lender.

          SECTION II.11. Change in Legality. (a) Notwithstanding anything to the
contrary herein contained, if any change in any law or regulation or in the
interpretation thereof by any governmental authority charged with the
administration or interpretation thereof shall make it unlawful for any Lender
to make or maintain any Eurodollar Loan or to give effect to its obligations to
make Eurodollar Loans as contemplated hereby, then, by written notice to
Borrowers and to the Administrative Agent, such Lender may:

               (i  declare that Eurodollar Loans will not thereafter be made by
          such Lender hereunder, whereupon the Borrowers shall be prohibited
          from requesting Eurodollar Loans from such Lender hereunder unless
          such declaration is subsequently withdrawn; and

               (ii  require that all outstanding Eurodollar Loans, made by such
          Lender be converted to Alternate Base Loans, in which event (A) all
          such Eurodollar Loans shall be automatically converted to Alternate
          Base Loans as of the effective date of such notice as provided in
          paragraph (b) below and (B) all payments of principal which would
          otherwise have been applied to repay the converted Eurodollar Loans
          shall instead be applied to repay the Alternate Base Loans resulting
          from the conversion of such Eurodollar Loans.

          (b  For purposes of Section 2.11(a) hereof, a notice to the Borrowers
by any Lender shall be effective, if lawful, on the last day of the then current
Interest Period or, if there are then two or more current Interest Periods, on
the last day of each such Interest Period, respectively; otherwise, such notice
shall be effective with respect to the Borrowers on the date of receipt by the
Borrowers.

                                       41
<PAGE>

          SECTION II.12. Indemnity. The Borrowers shall indemnify the
Administrative Agent and each Lender against any loss or reasonable expense
(including, but not limited to, any loss or reasonable expense sustained or
incurred or to be sustained or incurred by reason of or in connection with the
execution and delivery or assignment of, or payment under, any Letter of Credit,
or in liquidating or employing deposits from third parties acquired to affect or
maintain any Loan or part thereof as a Eurodollar Loan) which the Administrative
Agent or such Lender may sustain or incur as a consequence of the following
events (regardless of whether such events occur as a result of the occurrence of
a Default or an Event of Default or the exercise of any right or remedy of the
Administrative Agent or the Lenders under this Agreement or any other agreement,
or at law): any failure of the Borrowers to fulfill on the date of any Credit
Event the applicable conditions set forth in Article V hereof applicable to it;
any failure of the Borrowers to borrow hereunder after irrevocable notice of
borrowing pursuant to Section 2.03 hereof has been given; any payment,
prepayment or conversion of a Eurodollar Loan on a date other than the last day
of the relevant Interest Period; any default in payment or prepayment of the
principal amount of any Loan or any part thereof or interest accrued thereon, or
with respect to any Letter of Credit, in each case, as and when due and payable
(at the due date thereof, by irrevocable notice of prepayment or otherwise); or
the occurrence of an Event of Default. Without limiting the foregoing, the
Borrowers further agree to indemnify and hold harmless the Administrative Agent,
each Lender as well as their respective officers and directors, each person who
controls the Administrative Agent or Lender within the meaning of Section 15 of
the Securities Act of 1933 or any applicable state securities law and their
respective successors, from and against any and all claims, damages, losses,
liabilities, costs or expenses, joint or several, to which they or any of them
may become subject under any Federal or state securities law, rule or
regulation, at common law or otherwise, insofar as such claims, damages, losses,
liabilities, costs or expenses arise out of or are based upon the execution and
delivery by the Administrative Agent or any Lender of any Letter of Credit or
the execution and delivery of any other document in connection therewith. Such
loss or reasonable expense shall include, without limitation, an amount equal to
the excess, if any, of (i) the amount of interest which would have accrued on
the principal or other amount so paid, prepaid or converted or not borrowed for
the period from the date of such payment, prepayment or conversion or failure to
borrow to, in the case of a Loan, the last day of the Interest Period for such
Loan (or, in the case of a failure to borrow, the Interest Period for such Loan
which would have commenced on the date of such failure to borrow), at the
applicable rate of interest for such Loan provided for herein over (ii) the
amount of interest (as reasonably determined by such Lender) that would be
realized by such Lender in reemploying the funds so paid, prepaid or converted
or not borrowed for such period or Interest Period, as the case may be. Any such
Lender shall provide to the Borrowers a statement, signed by an officer of such
Lender, explaining any loss or expense and setting forth, if applicable, the
computation pursuant to the preceding sentence, and such statement shall be
conclusive absent manifest error. The

                                       42
<PAGE>

Borrowers shall pay such Lender the amount shown as due on any such statement
within ten (10) days after the receipt of the same. The indemnities contained
herein shall survive the expiration or termination of this Agreement and of the
Letters of Credit.

          SECTION II.13.  Pro Rata Treatment; Assumption by and Delegation of
Authority to the Administrative Agent. (a) Except as permitted under Sections
2.10, 2.11 and 2.16 hereof or as described in subsection (d) below, each
borrowing, each payment or prepayment of principal of the Notes, each payment of
interest on the Notes, each payment of any fee or other amount payable hereunder
and each reduction of the Total Revolving Credit Commitment shall be made pro
rata among the Lenders in the proportions that their Revolving Credit
Commitments bear to the Total Revolving Credit Commitment or that the aggregate
principal amount of such Lender's Term Loan bears to the aggregate principal
amount of the Term Loans made by all of the Lenders, as the case may be.

          (b)  Notwithstanding the occurrence or continuance of a Default or
Event of Default or other failure of any condition to the making of Loans or
occurrence of other Credit Events hereunder subsequent to the Credit Events on
the Closing Date, unless the Administrative Agent shall have been notified in
writing by any Lender in accordance with the provisions of paragraph (c) below
prior to the date of a proposed Credit Event that such Lender will not make the
amount that would constitute its pro rata share of the applicable Credits on
such date available to the Administrative Agent, the Administrative Agent may
assume that such Lender has made such amount available to the Administrative
Agent on such date, and the Administrative Agent may, in reliance upon such
assumption, make available to the Borrowers a corresponding amount. If such
amount is made available to the Administrative Agent on a date after such Credit
Event date, such Lender shall pay to the Administrative Agent on demand an
amount equal to the product of (i) the daily average Federal funds rate during
such period as quoted by the Administrative Agent, times (ii) the amount of such
Lender's pro rata share of such Credits, times (iii) a fraction the numerator of
which is the number of days that elapse from and including such Credit Event
date to the date on which such Lender's pro rata share of such Credits shall
have become immediately available to the Administrative Agent and the
denominator of which is 360. A certificate of the Administrative Agent submitted
to any Lender with respect to any amounts owing under this subsection shall be
conclusive in the absence of manifest error. If such Lender's pro rata share of
such Credits is not in fact made available to the Administrative Agent by such
Lender within three Business Days of such Credit Event date, the Administrative
Agent shall be entitled to recover such amount with interest thereon at the rate
per annum applicable to the Loans hereunder, on demand, from the Borrowers.

          (c)  Unless and until the Administrative Agent shall have received
notice from the Required Lenders as to the existence of a Default, an Event of
Default or some other circumstance which would relieve the Lenders of their
respective obligations to extend Credits hereunder, which notice shall be in
writing and shall be

                                       43
<PAGE>

signed by the Required Lenders and shall expressly state that the Required
Lenders do not intend to make available to the Administrative Agent such
Lenders' ratable share of Credits extended after the effective date of such
notice, the Administrative Agent shall be entitled to continue to make the
assumptions described in Section 2.13(b) above. After receipt of the notice
described in the preceding sentence, which shall become effective on the third
Business Day after receipt of such notice by the Administrative Agent (unless
otherwise agreed by the Administrative Agent), the Administrative Agent shall be
entitled to make the assumptions described in Section 2.13(b) above as to any
Credits as to which it has not received a written notice to the contrary prior
to 11:00 A.M. (Los Angeles, California time) on the Business Day next preceding
the day on which such Credits are to be extended. The Administrative Agent shall
not be required to extend any Credits as to which it shall have received notice
by a Lender of such Lender's intention not to make its ratable portion of such
Credits available to the Administrative Agent. Any withdrawal of authorization
as described under this Section 2.13(c) shall not affect the validity of any
Credits extended prior to the effectiveness thereof.

          (d)  In the event that any Lender fails to fund its ratable portion
(based on its Revolving Credit Commitment) of any Revolving Credit Loan which
such Lender is obligated to fund under the terms of this Agreement (the funded
portion of such borrowing being hereinafter referred to as a "Non Pro Rata
Loan"), until the earlier of such Lender's cure of such failure or the
termination of the Total Revolving Credit Commitment, in the Administrative
Agent's sole discretion, the proceeds of all amounts thereafter repaid to the
Administrative Agent for the benefit of the Lenders by the Borrowers and
otherwise required to be applied to such Lender's share of any other Obligation
pursuant to the terms of this Agreement, may be advanced to the Borrowers by the
Administrative Agent on behalf of such Lender to cure, in full or in part, such
failure by such Lender, but shall nevertheless be deemed to have been paid to
such Lender in satisfaction of such other Obligation. Notwithstanding anything
in this Agreement to the contrary:

               (i) the foregoing provisions to this subsection (d) shall apply
          only with respect to the proceeds of payments of Obligations and shall
          not affect the conversion or continuation of Loans pursuant to Section
          2.02;

               (ii) any such Lender shall be deemed to have cured its failure to
          fund at such time as an amount equal to such Lender's ratable portion
          (based on its Revolving Credit Commitment) of the requested principal
          portion of such Revolving Credit Loan is fully funded to the Borrowers
          whether made by such Lender itself or by operation of the terms of
          this subsection (d) and whether or not the Non Pro Rata Loan with
          respect thereto has been converted or continued;

               (iii) amounts advanced to the Borrowers to cure, in full or in
          part, any such Lender's failure to fund its Revolving Credit Loans
          ("Cure

                                       44
<PAGE>

          Loans") shall bear interest at the rate applicable to Alternate Base
          Loans under Section 2.05 in effect from time to time, and for all
          other purposes of this Agreement shall be treated as if they were
          Alternate Base Loans;

               (iv) regardless of whether or not an Event of Default has
          occurred and is continuing, and notwithstanding the instructions of
          the Borrowers as to their desired application, all repayments of
          principal which would be applied to the outstanding Revolving Credit
          Alternate Base Loans shall be applied first, ratably to Revolving
          Credit Alternate Base Loans constituting Non Pro Rata Loans, second,
          ratably to Revolving Credit Alternate Base Loans other than those
          constituting Non Pro Rata Loans or Cure Loans and, third, ratably to
          Revolving Credit Alternate Base Loans constituting Cure Loans;

               (v) for so long as, and until the earlier of any such Lender's
          cure of the failure to fund its ratable portion (based on its
          Revolving Credit Commitment) of any Revolving Credit Loan and the
          termination of the Total Revolving Credit Commitment, the term
          "Required Lenders" for all purposes of this Agreement shall exclude
          all Lenders whose failure to fund their ratable portion (based on
          their respective Revolving Credit Commitments) of any Revolving Credit
          Loan have not been cured; and

               (vi) for so long as and until any such Lender's failure to fund
          its ratable portion (based on its Revolving Credit Commitment) of any
          Revolving Credit Loan is cured in accordance with this subsection (d),
          such Lender shall not be entitled to any Revolving Credit Commitment
          Fee with respect to its Revolving Credit Commitment.

          SECTION II.14. Sharing of Setoffs. Each Lender agrees that if it
shall, through the exercise of a right of banker's lien, setoff or counterclaim
against the Borrowers, including, but not limited to, a secured claim under
Section 506 of Title 11 of the United States Code or other security or interest
arising from, or in lieu of, such secured claim, received by such Lender under
any applicable bankruptcy, insolvency or other similar law or otherwise, obtain
payment (voluntary or involuntary) in respect of a Note or exposure under the
Letter of Credit Usage held by it as a result of which the unpaid principal
portion of the Notes or exposure under the Letter of Credit Usage held by it
shall be proportionately less than the unpaid principal portion of the Notes or
exposure under the Letter of Credit Usage held by any other Lender, it shall be
deemed to have simultaneously purchased from such other Lender a participation
in the Notes and exposure under the Letter of Credit Usage held by such other
Lender, so that the aggregate unpaid principal

                                       45
<PAGE>

amount of the Notes and exposure under the Letter of Credit Usage and
participations in Notes and exposure under the Letter of Credit Usage held by it
shall be in the same proportion to the aggregate unpaid principal amount of all
Notes and exposure under the Letter of Credit Usage then outstanding as the
principal amount of the Notes and exposure under the Letter of Credit Usage held
by it prior to such exercise of banker's lien, setoff or counterclaim was to the
principal amount of all Notes and exposure under the Letter of Credit Usage
outstanding prior to such exercise of banker's lien, setoff or counterclaim;
provided, however, that if any such purchase or purchases or adjustments shall
be made pursuant to this Section 2.14 and the payment giving rise thereto shall
thereafter be recovered, such purchase or purchases or adjustments shall be
rescinded to the extent of such recovery and the purchase price or prices or
adjustments restored without interest. The Borrowers expressly consent to the
foregoing arrangements and agree that any Lender holding a participation in a
Note and exposure under the Letter of Credit Usage deemed to have been so
purchased may exercise any and all rights of banker's lien, setoff or
counterclaim with respect to any and all moneys owing by the Borrowers to such
Lender as fully as if such Lender held a Note and exposure under the Letter of
Credit Usage in the amount of such participation.

          SECTION II.15. Payments and Computations. (a) The Borrowers shall make
each payment hereunder and under any instrument delivered hereunder not later
than 12:00 noon (Los Angeles, California time) on the day when due in lawful
money of the United States (in freely transferable dollars) to the
Administrative Agent at its offices at 100 Pringle Avenue, Suite 650, Walnut
Creek, California 94596 for the account of the Lenders, in immediately available
funds, without set-off or counterclaim. Any amounts received after such time on
any date may, in the discretion of the Administrative Agent, be deemed to have
been received on the next succeeding Business Day for purposes of calculating
interest thereon. The Administrative Agent shall distribute any such payments
received by it for the account of any other person to the appropriate recipient
promptly following receipt thereof. The Administrative Agent may charge, when
due and payable, the Borrowers' account with the Administrative Agent for all
interest, principal and Revolving Credit Commitment Fees or other fees owing to
the Administrative Agent or the Lenders on or with respect to this Agreement
and/or the Loans and other Loan Documents. If at any time there is not
sufficient availability to cover any of the payments referred to in the prior
sentence, and in any event upon the occurrence of any Default, the Borrowers
shall make any such payments upon demand.

          (b) If the Administrative Agent pays an amount to a Lender under this
Agreement in the belief or expectation that a related payment has been or will
be received by the Administrative Agent from Borrower and such related payment
is not received by the Administrative Agent, then the Administrative Agent will
be entitled to recover such amount from such Lender without setoff, counterclaim
or deduction of any kind. If the Administrative Agent determines at any time
that any amount received by the Administrative Agent under this Agreement must
be returned to Borrowers or paid to any other person pursuant to any solvency
law or otherwise, then, notwithstanding any other term or condition of this
Agreement, the Administrative Agent will not be

                                       46
<PAGE>

required to distribute any portion thereof to any Lender. In addition, each
Lender will repay to the Administrative Agent on demand any portion of such
amount that Agent has distributed to such Lender, together with interest at such
rate, if any, as the Administrative Agent is required to pay to Borrowers or
such other person, without setoff, counterclaim or deduction of any kind.

          SECTION II.16. Taxes. (a) Any and all payments by the Borrowers
hereunder shall be made, in accordance with Section 2.15 hereof, free and clear
of and without deduction for any and all present or future taxes, levies,
imposts, deductions, charges or withholdings in any such case imposed by the
United States or any political subdivision thereof, excluding:

               (i) in the case of the Administrative Agent and each Lender,
          taxes imposed or based on its net income, and franchise or capital
          taxes imposed on it, (A) if the Administrative Agent or such Lender is
          organized under the laws of the United States or any political
          subdivision thereof and (B) if the Administrative Agent or such Lender
          is not organized under the laws of the United States or any political
          subdivision thereof, and its principal office or Applicable Lending
          Office is located in the United States, and in the case of both (A)
          and (B), withholding taxes payable with respect to payments to the
          Administrative Agent or such Lender at its principal office or
          Applicable Lending Office under laws (including, without limitation,
          any treaty, ruling, determination or regulation) in effect on the date
          hereof, but not any increase in withholding tax resulting from any
          subsequent change in such laws (other than withholding with respect to
          taxes imposed or based on its net income or with respect to franchise
          or capital taxes), and

               (ii) taxes (including withholding taxes) imposed by reason of the
          failure of the Administrative Agent or any Lender, in either case that
          is organized outside the United States, to comply with Section 2.16(f)
          hereof (or the inaccuracy at any time of the certificates, documents
          and other evidence delivered thereunder)

(all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings
and liabilities being hereinafter referred to as "Taxes"). If the Borrowers
shall be required by law to deduct any Taxes from or in respect of any sum
payable hereunder to the Lenders or the Administrative Agent, (x) the sum
payable shall be increased by the amount necessary so that after making all
required deductions (including without limitation deductions applicable to
additional sums payable under this Section 2.16) such Lender or the
Administrative Agent (as the case may be) receives an amount equal to the sum it
would have received had no such deductions been made, (y) the Borrowers shall
make such deductions and (z) the Borrowers shall pay the full amount

                                       47
<PAGE>

deducted to the relevant tax authority or other authority in accordance with
applicable law.

          (b) In addition, the Borrowers agree to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies which arise from any payment made hereunder or from the
execution, delivery or registration of, or otherwise with respect to, this
Agreement (hereinafter referred to as "Other Taxes").

          (c) The Borrowers will indemnify each Lender and the Administrative
Agent for the full amount of Taxes or Other Taxes (including, without
limitation, any Taxes or Other Taxes imposed by any jurisdiction (except as
specified in clauses (a)(i) and (ii)) on amounts payable under this Section
2.16) paid by such Lender or the Administrative Agent (as the case may be) and
any liability (including penalties, interest and expenses) arising therefrom or
with respect thereto. This indemnification shall be made within 30 days from the
date such Lender or the Administrative Agent (as the case may be) makes written
demand therefor. If any Lender receives a refund in respect of any Taxes or
Other Taxes for which such Lender has received payment from the Borrowers
hereunder, such Lender shall promptly notify the Borrowers of such refund and
such Lender shall, within 30 days of receipt of a request by the Borrowers,
repay such refund to the Borrowers, provided that the Borrowers, upon the
request of such Lender, agrees to return such refund (plus any penalties,
interest or other charges) to such Lender in the event such Lender is required
to repay such refund.

          (d) Within 30 days after the date of any payment of Taxes or Other
Taxes withheld by the Borrowers in respect of any payment to any Lender, the
Borrowers will furnish to the Administrative Agent, at its address referred to
in Section 11.01 hereof, such certificates, receipts and other documents as may
be reasonably required to evidence payment thereof.

          (e) Without prejudice to the survival of any other agreement
hereunder, the agreements and obligations contained in this Section 2.16 shall
survive the payment in full of principal and interest hereunder.

          (f) Each Lender that is organized outside of the United States shall
deliver to the Borrowers on the date hereof (or, in the case of an assignee, on
the date of the assignment) and from time to time as required for renewal under
applicable law duly completed copies of United States Internal Revenue Service
Form 1001 or 4224 (or any successor or additional forms), as appropriate,
indicating in each case that such Lender is entitled to receive payments under
this Agreement without any deduction or withholding of any United States federal
income taxes. The Administrative Agent (if the Administrative Agent is an entity
organized outside the United States) and each Lender that is organized outside
the United States shall promptly notify the Borrowers and the Administrative
Agent of any change in its Applicable Lending Office and upon written

                                       48
<PAGE>

request of the Borrowers such Lender shall, prior to the immediately following
due date of any payment by the Borrowers or any Guarantor hereunder or under any
other Loan Document, deliver to the Borrowers or such Guarantor, as the case may
be (with copies to the Administrative Agent), such certificates, documents or
other evidence, as required by the Code or Treasury Regulations issued pursuant
thereto, including without limitation Internal Revenue Service Form 4224, Form
1001 and any other certificate or statement of exemption required by Treasury
Regulation Section 1.1441-4(a) or Section 1.1441-6(c) or any subsequent version
thereof, properly completed and duly executed by such Lender establishing that
such payment is (i) not subject to withholding under the Code because such
payment is effectively connected with the conduct by such Lender of a trade or
business in the United States or (ii) totally exempt from United States tax
under a provision of an applicable tax treaty. The Borrowers shall be entitled
to rely on such forms in their possession until receipt of any revised or
successor form pursuant to this Section 2.16(f). If the Administrative Agent or
a Lender fails to provide a certificate, document or other evidence required
pursuant to this Section 2.16(f), then (i) the Borrowers shall be entitled to
deduct or withhold on payments to the Administrative Agent or such Lender as a
result of such failure, as required by law, and (ii) the Borrowers shall not be
required to make payments of additional amounts with respect to such withheld
Taxes pursuant to clause (x) of Section 2.16(a) to the extent such withholding
is required solely by reason of the failure of the Administrative Agent or such
Lender to provide the necessary certificate, document or other evidence.

          (g) Each Lender and the Administrative Agent shall use reasonable
efforts to avoid or minimize any amounts which might otherwise be payable
pursuant to this subsection 2.16 (including seeking refunds of any amounts that
are reasonably believed not to have been correctly or legally asserted);
provided, however, that such efforts shall not include the taking of any actions
by such Lender or the Administrative Agent that would result in any tax, costs
or other expense to such Lender or the Administrative Agent (other than a tax,
cost or other expense for which such Lender or the Administrative Agent shall
have been reimbursed or indemnified by the Borrowers pursuant to this Agreement
or otherwise) or any action which would or might in the reasonable opinion of
such Lender or the Administrative Agent have an adverse effect upon its
business, operations or financial condition or otherwise be disadvantageous to
such Lender or the Administrative Agent.

          SECTION II.17. Issuance of Letters of Credit. Upon the request of the
Borrowers, and subject to the conditions set forth in Article V hereof and such
other conditions to the opening of Letters of Credit as the Administrative Agent
requires of its customers generally, the Administrative Agent shall from time to
time open standby letters of credit (each, a "Letter of Credit") for the account
of the Borrowers, the aggregate undrawn amount of all outstanding Letters of
Credit not at any time to exceed $1,000,000; provided, however, that the
Borrowers may not request the Administrative Agent to open a Letter of Credit if
after giving effect thereto (measured

                                       49
<PAGE>

by the face amount of such Letter of Credit) the sum of the aggregate principal
amount of the Revolving Credit Loans outstanding hereunder plus the Letter of
Credit Usage would exceed the Total Revolving Credit Commitment. The issuance of
each Letter of Credit shall be made on at least three (3) Business Days' prior
written notice from the Borrowers to the Administrative Agent, at its Domestic
Lending Office, which written notice shall be an application for a Letter of
Credit on the Administrative Agent's customary form completed to the
satisfaction of the Administrative Agent, together with the proposed form of the
Letter of Credit (which shall be satisfactory to the Administrative Agent) and
such other certificates, documents and other papers and information as the
Administrative Agent may reasonably request. The Administrative Agent shall not
at any time be obligated to issue any Letter of Credit if such issuance would
conflict with, or cause the Administrative Agent or any Lender to exceed any
limits imposed by, any applicable requirements of law. The expiration date of
any standby Letter of Credit shall not be later than 365 days from the date of
issuance thereof, and, in any event, no Letter of Credit shall have an
expiration date later than the Conversion Date. The Letters of Credit shall be
issued with respect of transactions occurring in the ordinary course of business
of the Borrowers.

          SECTION II.18. Payment of Letters of Credit; Reimbursement. Upon the
issuance of any Letter of Credit, the Administrative Agent shall notify each
Lender of the principal amount, the number, and the expiration date thereof and
the amount of such Lender's participation therein. By the issuance of a Letter
of Credit hereunder and without further action on the part of the Administrative
Agent or the Lenders, each Lender hereby accepts from the Administrative Agent a
participation (which participation shall be nonrecourse to the Administrative
Agent) in such Letter of Credit equal to such Lender's pro rata (based on its
Revolving Credit Commitment) share of such Letter of Credit, effective upon the
issuance of such Letter of Credit. Each Lender hereby absolutely and
unconditionally assumes, as primary obligor and not as a surety, and agrees to
pay and discharge, and to indemnify and hold the Administrative Agent harmless
from liability in respect of, such Lender's pro rata share of the amount of any
drawing under a Letter of Credit. Each Lender acknowledges and agrees that its
obligation to acquire participations in each Letter of Credit issued by the
Administrative Agent and its obligation to make the payments specified herein,
and the right of the Administrative Agent to receive the same, in the manner
specified herein, are absolute and unconditional and shall not be affected by
any circumstance whatsoever, including, without limitation, the occurrence and
continuance of a Default or an Event of Default hereunder, and that each such
payment shall be made without any offset, abatement, withholding or reduction
whatsoever. The Administrative Agent shall review, on behalf of the Lenders,
each draft and any accompanying documents presented under a Letter of Credit and
shall notify each Lender of any such presentment. Promptly after it shall have
ascertained that any draft and any accompanying documents presented under such
Letter of Credit appear on their face to be in substantial conformity with the
terms and conditions of the Letter of Credit, the Administrative Agent shall
give telephonic or

                                       50
<PAGE>

facsimile notice to the Lenders and the Borrowers of the receipt and amount of
such draft and the date on which payment thereon will be made, and the Lenders
shall, by 11:00 A.M., Los Angeles, California time on the date such payment is
to be made, pay the amounts required to the Administrative Agent in Walnut
Creek, California in immediately available funds, and the Administrative Agent,
not later than 3:00 P.M. Los Angeles, California time on such day, shall make
the appropriate payment to the beneficiary of such Letter of Credit. If in
accordance with the prior sentence the Lenders shall pay any draft presented
under a Letter of Credit, then the Administrative Agent, on behalf of the
Lenders, shall charge the general deposit account of the Borrowers with the
Administrative Agent for the amount thereof, together with the Administrative
Agent's customary overdraft fee in the event the funds available in such account
shall not be sufficient to reimburse the Lenders for such payment and the
Borrowers shall not otherwise have discharged such reimbursement obligation by
11:00 A.M., Los Angeles, California time, on the date of such payment. If the
Lenders have not been reimbursed with respect to such drawing as provided above,
the Borrowers shall pay to the Administrative Agent, for the account of the
Lenders, the amount of the drawing together with interest on such amount at a
rate per annum (computed on the basis of the actual number of days elapsed over
a year of 360 days) equal to the rate applicable to Alternate Base Loans
hereunder plus two percent (2%), payable on demand. The obligations of the
Borrowers under this Section 2.18 to reimburse the Lenders and the
Administrative Agent for all drawings under Letters of Credit shall be joint and
several, absolute, unconditional and irrevocable and shall be satisfied strictly
in accordance with their terms, irrespective of:

          (a) any lack of validity or enforceability of any Letter of Credit;

          (b) the existence of any claim, setoff, defense or other right which
     the Borrowers or any other person may at any time have against the
     beneficiary under any Letter of Credit, the Administrative Agent or any
     Lender (other than the defense of payment in accordance with the terms of
     this Agreement or a defense based on the gross negligence or willful
     misconduct of the Administrative Agent or any Lender) or any other person
     in connection with this Agreement or any other transaction;

          (c) any draft or other document presented under any Letter of Credit
     proving to be forged, fraudulent, invalid or insufficient in any respect or
     any statement therein being untrue or inaccurate in any respect;

          (d) payment by the Administrative Agent or any Lender under any Letter
     of Credit against presentation of a draft or other document which does not
     comply with the terms of such Letter of Credit; and

          (e) any other circumstance or event whatsoever, whether or not similar
     to any of the foregoing.

                                       51
<PAGE>

          It is understood that in making any payment under any Letter of Credit
(x) the Administrative Agent's and any Lender's exclusive reliance on the
documents presented to it under such Letter of Credit as to any and all matters
set forth therein, including, without limitation, reliance on the amount of any
draft presented under such Letter of Credit, whether or not the amount due to
the beneficiary equals the amount of such draft and whether or not any document
presented pursuant to such Letter of Credit proves to be insufficient in any
respect, if such document on its face appears to be in order, and whether or not
any other statement or any other document presented pursuant to such Letter of
Credit proves to be forged or invalid or any statement therein proves to be
inaccurate or untrue in any respect whatsoever and (y) any noncompliance in any
immaterial respect of the documents presented under such Letter of Credit with
the terms thereof shall, in each case, not be deemed willful misconduct or gross
negligence of the Administrative Agent or any Lender.

          SECTION II.19. Administrative Agent's Actions with respect to Letters
of Credit. Any Letter of Credit may, in the discretion of the Administrative
Agent or its correspondents, be interpreted by them (to the extent not
inconsistent with such Letter of Credit) in accordance with the Uniform Customs
and Practice for Documentary Credits of the International Chamber of Commerce,
as adopted or amended from time to time, or any other rules, regulations and
customs prevailing at the place where any Letter of Credit is available or the
drafts are drawn or negotiated. The Administrative Agent and its correspondents
may accept and act upon the name, signature, or act of any party purporting to
be the executor, administrator, receiver, trustee in bankruptcy, or other legal
representative of any party designated in any Letter of Credit in the place of
the name, signature, or act of such party.

          SECTION II.20. Letter of Credit Fees. The Borrowers agree to pay (i)
to the Administrative Agent for the account of each Lender a participation fee
with respect to its participations in Letters of Credit, which shall accrue at a
rate per annum equal to the margin over the Adjusted LIBO Rate applicable to
interest on Eurodollar Loans on the average daily amount of such Lender's pro
rata share of the Letter of Credit Usage (excluding any portion attributable to
unreimbursed drawings) during the period from and including the Closing Date to
but excluding the later of the date on which such Lender's Revolving Credit
Commitment terminates and the date on which such Lender ceases to have any share
of the Letter of Credit Usage, and (ii) an issuance fee and other related fees
charged by the Administrative Agent for transactions of this nature as set forth
on Schedule 2.20 hereto (as such Schedule may be amended from time to time)
payable to the Administrative Agent for its own account at its Domestic Lending
Office in immediately available funds. Participation fees and other fees accrued
through and including the last day of September, December, March and June of
each year shall be payable on the first Business Day following each such period,
commencing October 1, 1998; provided that all such fees shall be payable on the
date on which the Revolving Credit Commitment terminates and any such fees

                                       52
<PAGE>

accruing after the date on which the Revolving Credit Commitment terminates
shall be payable on demand. Any other fees payable to the Administrative Agent
pursuant to this paragraph shall be payable within 10 days after demand. All
participation fees and fronting fees shall be computed on the basis of a year of
360 days and shall be payable for the actual number of days elapsed (including
the first day but excluding the last day).


III. COLLATERAL SECURITY

          SECTION III.1. Security Documents. The Obligations shall be secured by
the Collateral described in the Security Documents and are entitled to the
benefits thereof. The Borrowers shall duly execute and deliver the Security
Documents, all consents of third parties necessary to permit the effective
granting of the Liens created in such agreements, financing statements pursuant
to the Uniform Commercial Code and other documents, all in form and substance
satisfactory to the Administrative Agent, as may be reasonably required by the
Administrative Agent to grant to the Lenders a valid, perfected and enforceable
first priority Lien on and security interest in (subject only to the Liens
permitted under Section 7.01 hereof) the Collateral.

          SECTION III.2. Filing and Recording. The Borrowers shall, at their
sole cost and expense, cause all instruments and documents given as evidence of
security pursuant to this Agreement to be duly recorded and/or filed or
otherwise perfected in all places necessary, in the opinion of the
Administrative Agent, and take such other actions as the Administrative Agent
may reasonably request, in order to perfect and protect the Liens of the
Administrative Agent and Lenders in the Collateral. The Borrowers, to the extent
permitted by law, hereby authorize the Administrative Agent to file any
financing statement in respect of any Lien created pursuant to the Security
Documents which may at any time be required or which, in the opinion of the
Administrative Agent, may at any time be desirable although the same may have
been executed only by the Administrative Agent or, at the option of the
Administrative Agent, to sign such financing statement on behalf of the
Borrowers and file the same, and the Borrowers hereby irrevocably designate the
Administrative Agent, its agents, representatives and designees as its agent and
attorney-in-fact for this purpose. In the event that any re-recording or
refiling thereof (or the filing of any statements of continuation or assignment
of any financing statement) is required to protect and preserve such Lien, the
Borrowers shall, at the Borrowers' cost and expense, cause the same to be
recorded and/or refiled at the time and in the manner requested by the
Administrative Agent.

IV.  REPRESENTATIONS AND WARRANTIES

                                       53
<PAGE>

          Each of the Borrowers and each of the Guarantors jointly and severally
represents and warrants to each of the Lenders and each of the Agents that both
before and after giving effect to the consummation of the Transactions:

          SECTION IV.1. Organization, Legal Existence. Each Loan Party is a
legal entity duly organized, validly existing and in good standing under the
laws of the jurisdiction of its organization, has the requisite power and
authority to own its property and assets and to carry on its business as now
conducted and as currently proposed to be conducted and is qualified to do
business in every jurisdiction where such qualification is required, except
where the failure to so qualify would not have a Material Adverse Effect (all
such jurisdictions being listed in Schedule 4.01 annexed hereto). Each Loan
Party has the corporate power to execute, deliver and perform its obligations
under this Agreement and the other Loan Documents to which it is a party, and to
borrow hereunder and to execute and deliver the Notes.

          SECTION IV.2. Authorization. The execution, delivery and performance
by each of the Loan Parties of this Agreement and each of the other Loan
Documents to which it is a party, the borrowings hereunder by the Borrowers, the
execution and delivery by the Borrowers of the Notes and the grant of security
interests in the Collateral created by the Security Documents (collectively, the
"Transactions") (a) have been duly authorized by all requisite corporate and, if
required, stockholder action and (b) will not (i) violate (A) any provision of
law, statute, rule or regulation or the certificate or articles of incorporation
or other applicable constitutive documents or the by-laws of any Loan Party, or
their respective subsidiaries, as the case may be, (B) any order of any court,
or any rule, regulation or order of any other agency of government binding upon
any Loan Party, or (C) any provisions of any material indenture, agreement or
other instrument to which any Loan Party, or their respective subsidiaries, or
any of their respective properties or assets are or may be bound, (ii) be in
conflict with, result in a breach of or constitute (alone or with notice or
lapse of time or both) a default under any material indenture, agreement or
other instrument referred to in (b)(i)(C) above or (iii) result in the creation
or imposition of any Lien of any nature whatsoever (other than in favor of the
Administrative Agent, for its own benefit and for the benefit of the Lenders, as
contemplated by this Agreement and the Security Documents) upon any property or
assets of any Loan Party.

          SECTION IV.3. Governmental Approvals. No registration or filing (other
than the filings necessary to perfect the Liens created by the Security
Documents) with consent or approval of, or other action by, any Federal, state
or other governmental agency, authority or regulatory body is or will be
required in connection with the Transactions, other than any which have been
made or obtained.

          SECTION IV.4. Binding Effect. This Agreement and each of the other
Loan Documents executed and delivered by any of the Loan Parties constitutes a
legal, valid and binding obligation of such person, and is enforceable in
accordance with its 

                                       54
<PAGE>

terms. Each of the Notes, when duly executed and delivered by the Borrowers,
will constitute a legal, valid and binding obligation of the Borrowers
enforceable in accordance with its terms.

          SECTION IV.5. Material Adverse Change. Except as set forth in Schedule
4.05 annexed hereto, there has been no material adverse change in the business,
assets, operations or financial condition of any of the Borrowers or any of
their subsidiaries since December 31, 1997. 

          SECTION IV.6. Litigation; Compliance with Laws; etc. (a) Except as set
forth in Schedule 4.06(a) annexed hereto, there are not any actions, suits or
proceedings at law or in equity or by or before any governmental instrumentality
or other agency or regulatory authority now pending or, to the knowledge of any
Responsible Officer of any Loan Party, threatened against or affecting any of
the Loan Parties or the businesses, assets or rights of any of the Loan Parties
(i) which involve any of the Transactions or (ii) as to which it is probable
(within the meaning of Statement of Financial Accounting Standards No. 5) that
there will be an adverse determination and which, if adversely determined,
would, individually or in the aggregate, materially impair the ability of any of
the Loan Parties to conduct business substantially as now conducted, or have a
Material Adverse Effect.

          (b) Except as set forth in Schedule 4.06(b) annexed hereto, no Loan
Party is in violation of any law, or in default with respect to any judgment,
writ, injunction, decree, rule or regulation of any court or governmental agency
or instrumentality, except where such violation or default would not have a
Material Adverse Effect. 

          SECTION IV.7. Financial Statements. (a) The Borrowers have 
heretofore furnished to the Administrative Agent the financial statements of 
the Borrowers for the six month period ended June 30, 1998. Such financial 
statements present fairly the Consolidated financial condition and results of 
operations of the Borrowers and their subsidiaries as of the dates and for 
the periods indicated, and such balance sheets and the notes thereto disclose 
all material liabilities, direct or contingent, of the Borrowers and their 
subsidiaries, as of the dates thereof.

          (b) The Borrowers have heretofore furnished to the Administrative
Agent updated quarterly, through December 31, 1998, and annual, thereafter
through the December 31, 2000, projected income statements, balance sheets and
cash flows of the Borrowers on a Consolidated basis together with a schedule
confirming the ability of the Borrowers to consummate the Transactions and
demonstrating prospective compliance with all financial covenants contained in
this Agreement, such projections disclosing all assumptions made by Borrowers in
formulating such projections and giving effect to the Transactions. The
projections are based upon reasonable estimates and assumptions, all of which
are reasonable in light of the conditions which existed at the time the
projections were made, have been prepared on the basis of the 

                                       55
<PAGE>

assumptions stated therein, and reflect as of the Closing Date the reasonable
estimate of the Borrowers of the results of operations and other information
projected therein.

          (c) The Borrowers have heretofore furnished to the Administrative
Agent a Consolidated pro forma balance sheet of the Borrowers and which sets
forth information before and after giving effect to the Transactions.

          (d) The financial statements referred to in this Section 4.07 have
been prepared in accordance with GAAP, in each case subject to normal year-end
audit adjustments and, in the case of the financial statements delivered
pursuant to clauses (b) and (c) above, subject to the absence of footnotes.

          SECTION IV.8. Federal Reserve Regulations. (a) No Loan Party is
engaged principally, or as one of its important activities, in the business of
extending credit for the purpose of purchasing or carrying Margin Stock.

          (b) No part of the proceeds of the Loans will be used, whether
directly or indirectly, and whether immediately, incidentally or ultimately, (i)
to purchase or carry Margin Stock or to extend credit to others for the purpose
of purchasing or carrying Margin Stock or to refund indebtedness originally
incurred for such purpose, or (ii) for any purpose which entails a violation of,
or which is inconsistent with, the provisions of the Regulations of the Board,
including, without limitation, Regulation T, U or X thereof. If requested by any
Lender, the Borrowers or any subsidiary thereof shall furnish to such Lender a
statement on Federal Reserve Form U-1 referred to in said Regulation U.

          SECTION IV.9. Taxes. Each Loan Party has filed or caused to be filed
all Federal, state, local and foreign tax returns which are required to be filed
by it, on or prior to the date hereof, other than tax returns in respect of
taxes that (x) are not franchise, capital or income taxes, (y) in the aggregate
are not material and (z) would not, if unpaid, result in the imposition of any
material Lien on any property or assets of any Loan Party. Each Loan Party has
paid or caused to be paid all taxes shown to be due and payable on such filed
returns or on any assessments received by it, other than (i) any taxes or
assessments the validity of which such Loan Party is contesting in good faith by
appropriate proceedings, and with respect to which such Loan Party shall, to the
extent required by GAAP have set aside on its books adequate reserves and (ii)
taxes other than income, capital or franchise taxes that in the aggregate are
not material and which would not, if unpaid, result in the imposition of any
material Lien on any property or assets of any Loan Party. No Federal income tax
returns of any Loan Party have been audited by the United States Internal
Revenue Service and no Loan Party has as of the date hereof requested or been
granted any extension of time to file any Federal, state, local or foreign tax
return. No Loan Party is party to or has any obligation under any tax sharing
agreement.

                                       56
<PAGE>

          SECTION IV.10. Employee Benefit Plans. With respect to the provisions
of ERISA, except as set forth on Schedule 4.10 hereto:

          (i) No Reportable Event has occurred or is continuing with respect to
any Pension Plan.

          (ii) No prohibited transaction (within the meaning of Section 406 of
ERISA or Section 4975 of the Code) has occurred with respect to any Plan subject
to Part 4 of Subtitle B of Title I of ERISA.

          (iii) None of the Borrowers or any ERISA Affiliate is now, or has been
during the preceding five years, obligated to contribute to a Pension Plan or a
Multiemployer Plan. None of the Borrowers or any ERISA Affiliate has (A) ceased
operations at a facility so as to become subject to the provisions of Section
4062(e) of ERISA, (B) withdrawn as a substantial employer so as to become
subject to the provisions of Section 4063 of ERISA, (C) ceased making
contributions to any Pension Plan subject to the provisions of Section 4064(a)
of ERISA to which the Borrowers, any subsidiary or any ERISA Affiliate made
contributions, (D) incurred or caused to occur a "complete withdrawal" (within
the meaning of Section 4203 of ERISA) or a "partial withdrawal" (within the
meaning of Section 4205 of ERISA) from a Multiemployer Plan that is a Pension
Plan so as to incur withdrawal liability under Section 4201 of ERISA (without
regard to subsequent reduction or waiver of such liability under Section 4207 or
4208 of ERISA), or (E) been a party to any transaction or agreement under which
the provisions of Section 4204 of ERISA were applicable.

          (iv) No notice of intent to terminate a Pension Plan has been filed,
nor has any Plan been terminated pursuant to the provisions of Section 4041(e)
of ERISA.

          (v) The PBGC has not instituted proceedings to terminate (or appoint a
trustee to administer) a Pension Plan and no event has occurred or condition
exists which might constitute grounds under the provisions of Section 4042 of
ERISA for the termination of (or the appointment of a trustee to administer) any
such Plan.

          (vi) With respect to each Pension Plan that is subject to the
provisions of Title I, Subtitle B, Part 3 of ERISA, the funding method used in
connection with such Plan is acceptable under ERISA, and the actuarial
assumptions and methods used in connection with funding such Pension Plan
satisfy the requirements of Section 302 of ERISA. The assets of each such
Pension Plan (other than the Multiemployer Plans) are at least equal to the
present value of the greater of (i) accrued benefits (both vested and
non-vested) under such Plan, or (ii) "benefit liabilities" (within the meaning
of Section 4001(a)(16) of ERISA) under such Plan, in each case as of the latest
actuarial valuation date for such Plan (determined in accordance with the same
actuarial assumptions and methods as those used by the Plan's actuary in its
valuation of such 

                                       57
<PAGE>

Plan as of such valuation date). No such Pension Plan has incurred any
"accumulated funding deficiency" (as defined in Section 412 of the Code),
whether or not waived.

          (vii) There are no actions, suits or claims pending (other than
routine claims for benefits) or, to the knowledge of the Responsible Officers of
any Loan Party, which could reasonably be expected to be asserted, against any
Plan or the assets of any such Plan. No civil or criminal action brought
pursuant to the provisions of Title I, Subtitle B, Part 5 of ERISA is pending
or, to the knowledge of the Responsible Officers of any Loan Party threatened
against any fiduciary or any Plan. None of the Plans or any fiduciary thereof
(in its capacity as such) has been the direct or indirect subject of any audit,
investigation or examination by any governmental or quasi-governmental agency.

          (viii) All of the Plans comply currently, and have complied in the
past, both as to form and operation, with their terms and with the provisions of
ERISA and the Code, and all other applicable laws, rules and regulations; all
necessary governmental approvals for the Plans have been obtained and a
favorable determination as to the qualification under Section 401(a) of the Code
of each of the Plans which is an employee pension benefit plan (within the
meaning of Section 3(2) of ERISA) has been made by the Internal Revenue Service
and a recognition of exemption from federal income taxation under Section 501(c)
of the Code of each of the funded employee welfare benefit plans (within the
meaning of Section 3(1) of ERISA) has been made by the Internal Revenue Service,
and nothing has occurred since the date of each such determination or
recognition letter that would adversely affect such qualification.

          SECTION IV.11. No Material Misstatements. No information, report,
financial statement, exhibit or schedule prepared or furnished by or on behalf
of any Loan Party to the Administrative Agent or any Lender in connection with
any of the Transactions or this Agreement, the Security Documents, the Notes or
any other Loan Documents or included therein contained or contains any material
misstatement of fact or omitted or omits to state any material fact necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

          SECTION IV.12. Investment Company Act; Public Utility Holding Company
Act. No Loan Party is an "investment company" as defined in, or is otherwise
subject to regulation under, the Investment Company Act of 1940. No Loan Party
is a "holding company" as that term is defined in or is otherwise subject to
regulation under, the Public Utility Holding Company Act of 1935.

          SECTION IV.13. Security Interest. Each of the Security Documents
creates and grants to the Administrative Agent, for its own benefit and for the
benefit of the Lenders, a legal, valid and perfected first (except as permitted
pursuant to Section 7.01 hereof) priority security interest in the collateral
identified therein. Such 

                                       58
<PAGE>

collateral or property is not subject to any other Liens whatsoever, except
Liens permitted by Section 7.01 hereof.

          SECTION IV.14. Use of Proceeds. All proceeds of each borrowing under
the Revolving Credit Commitment on the Closing Date, if any, shall be used to
partially refinance existing Indebtedness of the Borrowers. All proceeds of each
subsequent borrowing under the Total Revolving Credit Commitment after the
Closing Date shall be used to finance the consideration required for Permitted
Acquisitions and to finance Permitted De Novo Capital Expenditures as well as
other capital improvements and to provide for working capital requirements and
for general corporate purposes of the Borrowers.

          SECTION IV.15. Subsidiaries. As of the Closing Date, Schedule 4.15
annexed hereto sets forth each subsidiary of each Borrower, its jurisdiction of
incorporation, its capitalization and ownership of capital stock of each
subsidiary.

          SECTION IV.16. Title to Properties; Possession Under Leases;
Trademarks. (a) Each Borrower and each of their subsidiaries has good and
marketable title to, or valid leasehold interest in, all of its respective
properties and assets shown on the most recent balance sheet referred to in
Section 4.07(a) hereof and all assets and properties acquired since the date of
such balance sheet, except for such properties as are no longer used or useful
in the conduct of its business or as have been disposed of in the ordinary
course of business, and except for minor defects in title that do not materially
interfere with the ability of any of the Borrowers or any subsidiary thereof to
conduct its business as now conducted. All such assets and properties are free
and clear of all Liens other than those permitted by Section 7.01 hereof.

          (b) Each Borrower and each of their subsidiaries has complied with all
obligations under all leases to which it is a party and under which it is in
occupancy, except where the failure to so comply would not have a Material
Adverse Effect, and all such leases are in full force and effect and each
Borrower and each of their subsidiaries enjoys peaceful and undisturbed
possession under all such leases.

          (c) Each Borrower and each of their subsidiaries owns or controls all
material trademarks, trademark rights, trade names, trade name rights,
copyrights, patents, patent rights and licenses which are necessary for the
conduct of the business of such Borrowers and such subsidiary. No Borrower or
subsidiary thereof is infringing upon or otherwise acting adversely to any of
such trademarks, trademark rights, trade names, trade name rights, copyrights,
patent rights or licenses owned by any other person or persons. There is no
claim or action by any such other person pending, or to the knowledge of any
Responsible Officer of any Borrower or any subsidiary thereof, threatened,
against any Borrowers or any subsidiary thereof with respect to any of the
rights or property referred to in this Section 4.16(c).

          SECTION IV.17. Solvency. (a) The fair salable value of the assets of
each Borrower and its Consolidated subsidiaries is not less than the amount that
will be required to be paid on or in respect of the probable liability on the
existing debts and other liabilities (including contingent liabilities) of such
Borrower and its Consolidated subsidiaries, as they become absolute and mature.
For the purposes hereof, the "fair saleable value" of assets shall mean the
price a buyer is willing to pay for such assets in an arm's-length transaction.

          (b) The assets of each Borrower and its Consolidated subsidiaries do
not constitute unreasonably small capital for such Borrowers and their
Consolidated subsidiaries to carry out their business as now conducted and as
proposed to be conducted including the capital needs of such Borrower and its
Consolidated subsidiaries, taking into account the particular capital
requirements of the business conducted by such Borrower and its Consolidated
subsidiaries and projected capital requirements and capital availability
thereof.

          (c) No Borrower or any subsidiary thereof intends to incur debts
beyond its ability to pay such debts as they mature (taking into account the
timing and amounts of cash to be received by such Borrower and such subsidiary,
and of amounts to be payable on or in respect of debt of such Borrowers and such
subsidiary). The cash flow of each Borrower and its Consolidated subsidiaries,
after taking into account all anticipated uses of the cash of such Borrower and
its Consolidated subsidiaries, will at all times be sufficient to pay all such
amounts on or in respect of debt of such Borrower and its Consolidated
subsidiaries when such amounts are required to be paid.

          (d) No Borrower or any subsidiary thereof believes that final
judgments against it in actions for money damages presently pending will be
rendered at a time when, or in an amount such that, it will be unable to satisfy
any such judgments promptly in accordance with their terms (taking into account
the maximum reasonable amount of such judgments in any such actions and the
earliest reasonable time at which such judgments might be rendered). The cash
flow of such Borrower and its Consolidated subsidiaries, after taking into
account all other anticipated uses of the cash of such Borrower and its
Consolidated subsidiaries (including the payments on or in respect of debt
referred to in paragraph (c) of this Section), will at all times be sufficient
to pay all such judgments promptly in accordance with their terms.

          SECTION IV.18. Permits, etc. Each Loan Party possesses all licenses,
permits, approvals and consents, including, without limitation, all
environmental, health and safety licenses, permits, approvals and consents
(collectively, "Permits") of all Federal, state and local governmental
authorities as required to conduct properly its business, each such Permit is
and will be in full force and effect, each Loan Party is in compliance in all
material respects with all such Permits, and no event (including, without
limitation, any violation of any law, rule or 

                                       60

Parties, any predecessor of any Loan Party has filed any notice under any
Environmental Law indicating past or present treatment, storage, or disposal of
a Hazardous Material or reporting a spill or Release of a Contaminant into the
environment; (v) to the best of the knowledge of the Responsible Officers of the
Loan Parties, no Loan Party has any contingent liability in connection with any
Release of any Contaminant into the environment; (vi) none of the operations of
the Loan Parties involve the generation, transportation, treatment or disposal
of Hazardous Materials, except for Hazardous Materials used in the ordinary
course of business of the Loan Parties in accordance in all material respects
with Environmental Laws; (vii) no Loan Party has disposed of any Contaminant by
placing it in or on the ground or waters of any premises owned, leased or used
by any of them and to the knowledge of the Loan Parties neither has any lessee,
prior owner, or other person; (viii) no underground storage tanks or surface
impoundments are on any property of the Loan Parties; and (ix) no Lien in favor
of any governmental authority for (A) any liability under any Environmental Law
or regulations, or (B) damages arising from or costs incurred by such
governmental authority in response to a Release of a Contaminant into the
environment, has been filed or attached to the property of the Loan Parties.

          SECTION IV.20. No Change in Credit Criteria or Collection Policies.
There has been no material change in credit criteria or collection policies
concerning account receivables of any of the Borrowers since December 31, 1997.
All account receivables are valid, binding and enforceable obligations of
account debtors, except to the extent reserves are taken in accordance with GAAP
with respect to contractual adjustments for account receivables.

          SECTION IV.21. Employee Matters. Except as disclosed in Schedule 4.21
hereto, (a) no Loan Party nor any of such person's employees are subject to any
collective bargaining agreement, (b) to the knowledge on the date hereof 

                                       61

of the Borrowers, the cost to the Borrowers of reprogramming and testing of the
Borrowers' and their subsidiaries' computer systems and related equipment to
permit proper functioning in and following the year 2000 (including, without
limitation, reprogramming errors) will not reasonably be expected to result in a
Material Adverse Effect.

liabilities of the Borrowers accrued hereunder shall automatically become due
and payable, both as to principal and interest, without presentment, demand,
protest or other notice of any kind, all of which are hereby expressly waived by
the Borrowers, anything contained herein or in the Notes to the contrary
notwithstanding.


IX.      AGENTS

                  In order to expedite the transactions contemplated by this
Agreement, Union Bank of California, N.A. is hereby appointed to act as
Administrative Agent on behalf of the Lenders. Each of the Lenders and each
subsequent holder of any Note or issuer of any Letter of Credit by its
acceptance thereof, irrevocably authorizes the Administrative Agent to take such
action on its behalf and to exercise such actions and powers hereunder and under
the Security Documents and other Loan Documents as are specifically delegated to
or required of the Administrative Agent by the terms hereof and the terms
thereof together with such actions and powers as are reasonably 


                                       89
<PAGE>


incidental thereto. Neither the Administrative Agent nor any of its directors,
officers, employees or agents shall be liable as such for any action taken or
omitted to be taken by it or them hereunder or under any of the Security
Documents and other Loan Documents or in connection herewith or therewith (a) at
the request or with the approval of the Required Lenders (or, if otherwise
specifically required hereunder or thereunder, the consent of all the Lenders)
or (b) in the absence of its or their own gross negligence or willful
misconduct. Notwithstanding any provisions to the contrary elsewhere herein or
in the other Loan Documents, the Administrative Agent shall not have any duties
or responsibilities except those expressly set forth herein or in the other Loan
Documents, and no implied covenants, functions, responsibilities, duties,
obligations or liabilities shall be read into the Credit Agreement or in the
other Loan Documents or otherwise exist against the Administrative Agent.

     The Administrative Agent is hereby expressly authorized on behalf of the
Lenders, without hereby limiting any implied authority, (a) to receive on behalf
of each of the Lenders any payment of principal of or interest on the Notes
outstanding hereunder and all other amounts accrued hereunder which are paid to
the Administrative Agent, and promptly to distribute to each Lender its proper
share of all payments so received, (b) to distribute to each Lender copies of
all notices, agreements and other material as provided for in this Agreement or
in the Security Documents and other Loan Documents as received by the
Administrative Agent (c) to maintain, in accordance with its customary business
practices, ledgers and records reflecting the status of the Loans, the
Collateral and related matters, (d) to open and maintain bank accounts and lock
boxes as the Administrative Agent deems necessary and appropriate in accordance
with the Loan Documents with respect to the Collateral, (e) to take all actions
with respect to this Agreement and the Security Documents and other Loan
Documents as are specifically delegated to the Administrative Agent, and (f) to
incur and pay such expenses as the Administrative Agent may deem necessary or
appropriate in connection with the foregoing.

     In the event that (a) any Borrowers fail to pay when due the principal of
or interest on any Note, any amount payable under any Letter of Credit, or any
fee payable hereunder or (b) the Administrative Agent receives written notice of
the occurrence of a Default or an Event of Default (the Administrative Agent
being deemed not to have knowledge of any Default or Event of Default unless and
until written notice thereof is given to the Administrative Agent by any
Borrower or a Lender), the Administrative Agent within a reasonable time shall
give written notice thereof to the Lenders, and shall take such action with
respect to such Event of Default or other condition or event as it shall be
directed to take by the Required Lenders; provided, however, that, unless and
until the Administrative Agent shall have received such directions, the
Administrative Agent may take such action or refrain from taking such action
hereunder or under the Security Documents or other Loan Documents with 


                                       90
<PAGE>


respect to a Default or Event of Default as it shall deem advisable in the best
interests of the Lenders.

     Neither the Administrative Agent nor the Syndication Agent (collectively,
the "Agents") shall be responsible in any manner to any of the Lenders for the
effectiveness, enforceability, perfection, value, genuineness, validity or due
execution of this Agreement, the Notes or any of the other Loan Documents or
Collateral or any other agreements or certificates, requests, financial
statements, notices or opinions of counsel or for any recitals, statements,
warranties or representations contained herein or in any such instrument or be
under any obligation to ascertain or inquire as to the performance or observance
of any of the terms, provisions, covenants, conditions, agreements or
obligations of this Agreement or any of the other Loan Documents or any other
agreements on the part of the Borrowers and, without limiting the generality of
the foregoing, the Agents shall, in the absence of knowledge to the contrary, be
entitled to accept any certificate furnished pursuant to this Agreement or any
of the other Loan Documents as conclusive evidence of the facts stated therein
and shall be entitled to rely on any note, notice, consent, certificate,
affidavit, letter, telegram, teletype message, statement, order or other
document which it believes in good faith to be genuine and correct and to have
been signed or sent by the proper person or persons. It is understood and agreed
that each of the Agents may exercise its rights and powers under other
agreements and instruments to which it is or may be a party, and engage in other
transactions with the Borrowers, as though it were not one of the Agents
hereunder.

     The Administrative Agent shall promptly give notice to the Lenders of the
receipt or sending of any material notice, schedule, report, projection,
financial statement or other document or information pursuant to this Agreement
or any of the other Loan Documents and shall promptly forward a copy thereof to
each Lender.

     Neither of the Agents nor any of their respective directors, officers,
employees or agents shall have any responsibility to the Borrowers on account of
the failure or delay in performance or breach by any Lender other than such
Agents of any of its obligations hereunder or to any Lender on account of the
failure of or delay in performance or breach by any other Lender or the
Borrowers of any of their respective obligations hereunder or in connection
herewith.

     Each of the Agents may consult with legal counsel selected by it in
connection with matters arising under this Agreement or any of the other Loan
Documents and any action taken or suffered in good faith by it in accordance
with the opinion of such counsel shall be full justification and protection to
it. Each of the Agents may exercise any of its powers and rights and perform any
duty under this Agreement or any of the other Loan Documents through agents or
attorneys.


                                       91
<PAGE>


     The Administrative Agent and the Borrowers may deem and treat the payee of
any Note as the holder thereof until written notice of transfer shall have been
delivered as provided herein by such payee to the Administrative Agent and the
Borrowers.

     With respect to the Loans made hereunder, the Notes issued to it and any
other Credit Event applicable to it, the Administrative Agent in its individual
capacity and not as an Administrative Agent shall have the same rights, powers
and duties hereunder and under any other agreement executed in connection
herewith as any other Lender and may exercise the same as though it were not the
Administrative Agent, and the Administrative Agent and its affiliates may accept
deposits from, lend money to and generally engage in any kind of business with
the Borrowers or other affiliate thereof as if it were not the Administrative
Agent. Each of the Lenders hereby acknowledges that each of the Agents and/or
one or more Affiliates of such Agents may at any time and from time to time be a
holder of equity interests in a Loan Party.

     Each Lender agrees (i) to reimburse each of the Agents in the amount of
such Lender's pro rata share (based on its Revolving Credit Commitment
hereunder) of any expenses incurred for its own benefit and/or for the benefit
of the Lenders by the Agents, including counsel fees and compensation of agents
and employees paid for services rendered on behalf of the Lenders, not
reimbursed by the Borrowers and (ii) to indemnify and hold harmless each of the
Agents and any of their respective directors, officers, employees or agents, on
demand, in the amount of its pro rata share, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind or nature whatsoever which may be
imposed on, incurred by or asserted against it in its capacity as the
Administrative Agent or any of them in any way relating to or arising out of
this Agreement or any of the other Loan Documents or any action taken or omitted
by it or any of them under this Agreement or any of the other Loan Documents, to
the extent not reimbursed by the Borrowers; provided, however, that no Lender
shall be liable to any of the Agents for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgment, suits, costs,
expenses or disbursements resulting from the gross negligence or willful
misconduct of such Agents or any of their respective directors, officers,
employees or agents. The foregoing agreement shall survive the repayment of all
Obligations and the termination of this Agreement.

     With respect to the release of Collateral, Lenders hereby irrevocably
authorize the Administrative Agent, at its option and in its discretion, to
release any Lien granted to or held by the Administrative Agent upon any
property covered by this Agreement or the other Loan Documents (i) upon
termination of the Total Revolving Credit Commitment and payment and
satisfaction of all Obligations; (ii) constituting property being sold or
disposed of in compliance with the provisions of this Agreement (and the
Administrative Agent may rely in good faith conclusively on any certificate to
such effect, without further inquiry); or (iii) constituting property leased to
any of the 


                                       92
<PAGE>


Borrowers or any of their subsidiaries under a lease which has expired or been
terminated in a transaction permitted under this Agreement or is about to expire
and which has not been, and is not intended by such Borrower or such subsidiary
to be, renewed or extended; provided, however, that (x) the Administrative Agent
shall not be required to execute any release on terms which, in the
Administrative Agent's opinion, would expose the Administrative Agent to
liability or create any obligation or entail any consequence other than the
release of such Liens without recourse or warranty, and (y) such release shall
not in any manner discharge, affect or impair the Obligations or any Liens upon
(or obligations of any Loan Party, in respect of), all interests retained by any
Loan Party, including (without limitation) the proceeds of any sale, all of
which shall continue to constitute part of the property covered by this
Agreement or the Loan Documents.

     With respect to perfecting Lenders' security interest in Collateral which,
in accordance with Article 9 of the Uniform Commercial Code in any applicable
jurisdiction, can be perfected only by possession, each Lender hereby appoints
each other Lender for the purpose of perfecting such interest. Should any Lender
(other than the Administrative Agent) obtain possession of any such Collateral,
such Lender shall notify the Administrative Agent, and, promptly upon the
Administrative Agent's request, shall deliver such Collateral to the
Administrative Agent or in accordance with the Administrative Agent's
instructions. Each Lender agrees that it will not have any right individually to
enforce or seek to enforce this Agreement or any Loan Document or to realize
upon any Collateral for the Loans, it being understood and agreed that such
rights and remedies may be exercised only by the Administrative Agent.

     In the event that a petition seeking relief under Title 11 of the United
States Code or any other Federal, state or foreign bankruptcy, insolvency,
liquidation or similar law is filed by or against any Loan Party, the
Administrative Agent is authorized to file a proof of claim on behalf of itself
and the Lenders in such proceeding for the total amount of Obligations owed by
such Loan Party. With respect to any such proof of claim which the
Administrative Agent may file, each Lender acknowledges that without reliance on
such proof of claim, such Lender shall make its own evaluation as to whether an
individual proof of claim must be filed in respect of such Obligations owed to
such Lender and, if so, take the steps necessary to prepare and timely file such
individual claim.

     Each Lender acknowledges that it has, independently and without reliance
upon the Agents or any other Lender and based on such documents and information
as it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement and any other Loan Document to which such Lender is party.
Each Lender also acknowledges that it will, independently and without reliance
upon the Agents or any other Lender and based on such documents and information
as it shall deem appropriate at the time, continue to make its own decisions in
taking or not 


                                       93
<PAGE>


taking action under or based upon this Agreement, any other Loan Document, any
related agreement or any document furnished hereunder.

     Subject to the appointment and acceptance of a successor Administrative
Agent as provided below, the Administrative Agent may resign at any time by
notifying the Lenders and the Borrowers. Upon any such resignation, the Lenders
shall have the right to appoint a successor Administrative Agent. If no
successor Administrative Agent shall have been so appointed by such Lenders and
shall have accepted such appointment within 30 days after the retiring
Administrative Agent gives notice of its resignation, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent which shall be a bank organized under the laws of the
United States, or any State thereof, having a combined capital and surplus of at
least $500,000,000. Upon the acceptance of any appointment as Administrative
Agent hereunder by a successor bank, such successor shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Administrative Agent and the retiring Administrative Agent shall be
discharged from its duties and obligations hereunder and under each of the other
Loan Documents. After any Administrative Agent's resignation hereunder, the
provisions of this Article shall continue in effect for its benefit in respect
of any actions taken or omitted to be taken by it while it was acting as
Administrative Agent.

     The Lenders hereby acknowledge that the Administrative Agent shall be under
no duty to take any discretionary action permitted to be taken by the
Administrative Agent pursuant to the provisions of this Agreement or any of the
other Loan Documents unless it shall be requested in writing to do so by the
Required Lenders. The Lenders further hereby acknowledge that neither of the
Agents is acting as the fiduciary of, or the trustee for, any of the Lenders and
except as expressly set forth herein, neither of the Agents shall have any duty
to disclose, and shall not be liable for the failure to disclose, any
information communicated to such Agents by or relating to the Borrowers or any
of their respective subsidiaries.


X.       COLLECTION OF RECEIVABLES

     The Borrowers and the Guarantors will, at the request of the Administrative
Agent, at their own cost and expense upon the occurrence of an Event of Default,
(i) arrange for remittances on Receivables owned by the Borrowers and the
Guarantors to be made directly to lockboxes designated by the Administrative
Agent or in such other manner as the Administrative Agent may direct, and (ii)
promptly deposit all payments received by the Borrowers and the Guarantors on
account of Receivables, whether in the form of cash, checks, notes, drafts,
bills of exchange, money orders or otherwise, in one or more accounts designated
by the Administrative Agent in precisely the form received (but with any
endorsements of the Borrowers necessary for deposit or collection), subject to
withdrawal by the Administrative Agent only, as hereinafter 


                                       94
<PAGE>


provided, and until such payments are deposited, such payments shall be deemed
to be held in trust by the Borrowers or the Guarantors, as the case may be, for
and as the Lenders' property and shall not be commingled with the Borrowers' or
the Guarantors', as the case may be, other funds.

     Upon the occurrence and continuance of an Event of Default, the
Administrative Agent may send a notice of assignment and/or notice of the
Administrative Agent's security interest to any and all Customers or any third
party holding or otherwise concerned with any of the Collateral, and thereafter
the Administrative Agent shall have the sole right to collect the Receivables
and/or take possession of the Collateral and the books and records relating
thereto. Neither the Borrowers nor the Guarantors shall, without the
Administrative Agent's prior written consent, grant any extension of the time of
payment of any Receivable, compromise or settle any Receivable for less than the
full amount thereof, release, in whole or in part, any person or property liable
for the payment thereof, or allow any credit or discount whatsoever thereon
except, prior to the occurrence and continuance of an Event of Default, as may
be customary in the Borrowers' or the Guarantors', as the case may be, business.

the Loans owing to, each Lender from time to time (the "Register"). The entries
in the Register shall be conclusive, in the absence of manifest error, and the
Borrowers, the Administrative Agent and the Lenders may treat each person whose

such assignee in an amount equal to its portion of the Revolving Credit
Commitment or of the Term Loan, assumed by it pursuant to such Assignment and
Acceptance and, if the assigning Lender has retained any Revolving Credit
Commitment or Term Loan hereunder, a new Note or Notes to the order of the
assigning Lender in an amount equal to the Revolving Credit Commitment or Term
Loan retained by it hereunder. Such new Note or Notes shall be in an aggregate
principal amount equal to the aggregate principal amount of such surrendered
Note or Notes, or, with respect to the Term Notes, the principal amount of the
Term Notes, outstanding at such time as evidenced by the Term Note or Notes,
shall be dated the effective date of such Assignment and Acceptance and shall
otherwise be in substantially the form of Exhibit A or Exhibit B, as the case
may be. Notes surrendered to the Borrowers shall be canceled by the Borrowers.

     (g) Notwithstanding any other provision herein, any Lender may, in
connection with any assignment or participation or proposed assignment or

assignee or participant, any information, including, without limitation, any
Information, relating to the Borrowers furnished to such Lender by or on behalf

the preparation of this Agreement and the other Loan Documents or with any

connection with this Agreement or any of the other Loan Documents or with the

disbursements of counsel for the Agents and ongoing field examination expenses
and charges, and, in connection with such enforcement or protection, the
reasonable fees and disbursements of counsel for the Lenders. Each of the
Borrowers further indemnifies the Lenders from and agrees to hold them harmless
against any documentary taxes, assessments or charges made by any governmental
authority by reason of the execution and delivery of this Agreement or the
Notes.

     (b) Each of the Borrowers indemnifies the Agents and each Lender and their
respective directors, officers, employees and agents against, and agrees to hold
the Agents, each Lender and each such person harmless from, any and all losses,
claims, damages, liabilities and related expenses, including reasonable counsel

related expenses to the extent that they result from the gross negligence or
willful misconduct of any Agent or any Lender.

     (c) Each of the Borrowers indemnifies, and agrees to defend and hold
harmless the Administrative Agent and the Lenders and their respective officers,


                                      100

<PAGE>



directors, shareholders, agents and employees (collectively, the
"Indemnitees") from and against any loss, cost, damage, liability, lien,
deficiency, fine, penalty or expense (including, without limitation, reasonable
attorneys' fees and reasonable expenses for investigation, removal, cleanup and
remedial costs and modification costs incurred to permit, continue or resume
normal operations of any property or assets or business of the Borrowers or any
subsidiary thereof) arising from a violation of, or failure to comply with any
Environmental Law and to remove any Lien arising therefrom except to the extent
caused by the gross negligence or willful misconduct of any Indemnitee, which
any of the Indemnitees may incur or which may be claimed or recorded against any
of the Indemnitees by any person.

     (d) The provisions of this Section 11.04 shall remain operative and in full
force and effect regardless of the expiration of the term of this Agreement, the
consummation of the transactions contemplated hereby, the repayment of any of
the Loans, the invalidity or unenforceability of any term or provision of this
Agreement or the Notes, or any investigation made by or on behalf of the Agents
or any Lender. All amounts due under this Section 11.04 shall be payable on
written demand therefor.


     SECTION XI.5. Applicable Law. THIS AGREEMENT AND THE NOTES SHALL BE
CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF CALIFORNIA
(OTHER THAN THE CONFLICTS OF LAWS PRINCIPLES THEREOF).


     SECTION XI.6. Right of Setoff. If an Event of Default shall have occurred
and be continuing, upon the request of the Required Lenders each Lender shall
and is hereby authorized at any time and from time to time, to the fullest
extent permitted by law, to set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by such Lender to or for the credit or the
account of any of the Borrowers against any and all of the obligations of the
Borrowers now or hereafter existing under this Agreement and the Notes held by
such Lender, irrespective of whether or not such Lender shall have made any
demand under this Agreement or the Notes and although such obligations may be
unmatured. Each Lender agrees to notify promptly the Administrative Agent and
the Borrowers after any such setoff and application made by such Lender, but the
failure to give such notice shall not affect the validity of such setoff and
application. The rights of each Lender under this Section are in addition to
other rights and remedies (including, without limitation, other rights of
setoff) which may be available to such Lender.

     SECTION XI.7. Payments on Business Days. (a) Should the principal of or
interest on the Notes or any fee or other amount payable hereunder become due
and payable on other than a Business Day, payment in respect thereof may be made
on the next succeeding Business Day (except as otherwise specified in 


                                      101
<PAGE>


the definition of "Interest Period"), and such extension of time shall in such
case be included in computing interest, if any, in connection with such payment.


     (b) All payments by any of the Borrowers hereunder and all Loans made by
the Lenders hereunder shall be made in lawful money of the United States of
America in immediately available funds at the office of the Administrative Agent
set forth in Section 11.01 hereof.

     SECTION XI.8. Waivers; Amendments. (a) No failure or delay of any Lender in
exercising any power or right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such right or power, preclude
any other or further exercise thereof or the exercise of any other right or
power. The rights and remedies of the Lenders hereunder are cumulative and not
exclusive of any rights or remedies which they may otherwise have. No waiver of
any provision of this Agreement or the Notes nor consent to any departure by any
of the Borrowers therefrom shall in any event be effective unless the same shall
be authorized as provided in paragraph (b) below, and then such waiver or
consent shall be effective only in the specific instance and for the purpose for
which given. No notice to or demand on any of the Borrowers in any case shall
entitle it to any other or further notice or demand in similar or other
circumstances. Each holder of any of the Notes shall be bound by any amendment,
modification, waiver or consent authorized as provided herein, whether or not
such Note shall have been marked to indicate such amendment, modification,
waiver or consent.

     (b) Neither this Agreement nor any provision hereof may be waived, amended
or modified except pursuant to an agreement or agreements in writing entered
into by the Borrowers and the Required Lenders; provided, however, that no such
agreement shall (i) change the principal amount of, or extend or advance the
maturity of or the dates for the payment of principal of or interest on, any
Note or reduce the rate of interest on any Note, (ii) change the Revolving
Credit Commitment of any Lender or amend or modify the provisions of this
Section, Section 2.06, Section 2.13, Section 4.14 or Section 11.04 hereof or the
definition of "Required Lenders," or (iii) release any material portion of
Collateral, in each case without the prior written consent of each Lender
affected thereby, and provided, further, however, that no such agreement shall
amend, modify or otherwise affect the rights or duties of the Agents under this
Agreement or the other Loan Documents without the written consent of the Agents.
Each Lender and holder of any Note shall be bound by any modification or
amendment authorized by this Section regardless of whether its Notes shall be
marked to make reference thereto, and any consent by any Lender or holder of a
Note pursuant to this Section shall bind any person subsequently acquiring a
Note from it, whether or not such Note shall be so marked.


                                      102
<PAGE>


     (c) In the event that the Borrowers request, with respect to this Agreement
or any other Loan Document, an amendment, modification or waiver and such
amendment, modification or waiver would require the unanimous consent of all of
the Lenders in accordance with Section 11.08(b) above, and such amendment,
modification or waiver is agreed to in writing by the Borrowers and the Required
Lenders but not by all of the Lenders, then notwithstanding anything to the
contrary in Section 11.08(b) above, with the written consent of the Borrowers
and such Required Lenders, the Borrowers and Required Lenders may, but shall not
be obligated to, amend this Agreement without the consent of the Lender or
Lenders who did not agree to the proposed amendment, modification or waiver (the
"Minority Lenders") solely to provide for (i) the termination of the Revolving
Credit Commitment of each Minority Lender, (ii) the assignment in accordance
with Section 11.03 hereof to one or more persons of each Minority Lender's
interests, rights and obligations under this Agreement (including, without
limitation, all of such Minority Lender's Revolving Credit Commitment as well as
its portion of all outstanding Loans and the Note or Notes held by such Minority
Lender) and the other Loan Documents and/or an increase in the Revolving Credit
Commitment of one or more Required Lenders, in each case so that after giving
effect thereto the Total Revolving Credit Commitment shall be in the same
amounts as prior to the events described in this paragraph, (iii) the repayment
to the Minority Lenders in full of all Loans outstanding and accrued interest
thereon at the time of the assignment and/or increase in Commitments described
in clause (ii) above with the proceeds of Loans made by such persons who are to
become Lenders by assignment or with the proceeds of Loans made by Required
Lenders who have agreed to increase their Revolving Credit Commitment, (iv) the
payment to the Minority Lenders by the Borrowers of all fees and other
compensation due and owing such Minority Lenders under the terms of this
Agreement and the other Loan Documents and (v) such other modifications as the
Required Lenders and Borrowers shall deem necessary in order to effect the
changes specified in clauses (i) through (iv) hereof.

     SECTION XI.9. Severability. In the event any one or more of the provisions
contained in this Agreement or in the Notes should be held invalid, illegal or
unenforceable in any respect, the validity, legality and enforceability of the
remaining provisions contained herein or therein shall not in any way be
affected or impaired thereby.


     SECTION XI.10. Entire Agreement; Waiver of Jury Trial, etc. (a) This
Agreement, the Notes and the other Loan Documents constitute the entire contract
between the parties hereto relative to the subject matter hereof. Any previous
agreement among the parties hereto with respect to the Transactions is
superseded by this Agreement, the Notes and the other Loan Documents. Except as
expressly provided herein or in the Notes or the Loan Documents (other than this
Agreement), nothing in this Agreement, the Notes or in the other Loan Documents,
expressed or implied, is intended to confer upon any party, other than the
parties hereto, any rights, 


                                      103
<PAGE>


remedies, obligations or liabilities under or by reason of this Agreement, the
Notes or the other Loan Documents.

     (b) Except as prohibited by law, each party hereto hereby waives any right
it may have to a trial by jury in respect of any litigation directly or
indirectly arising out of, under or in connection with this Agreement, the
Notes, any of the other Loan Documents or the Transactions.

     (c) Except as prohibited by law, each party hereto hereby waives any right
it may have to claim or recover in any litigation referred to in paragraph (b)
of this Section 11.10 any special, exemplary, punitive or consequential damages
or any damages other than, or in addition to, actual damages.

     (d) Each party hereto (i) certifies that no representative, agent or
attorney of any Lender has represented, expressly or otherwise, that such Lender
would not, in the event of litigation, seek to enforce the foregoing waivers and
(ii) acknowledges that it has been induced to enter into this Agreement, the
Notes or the other Loan Documents, as applicable, by, among other things, the
mutual waivers and certifications herein.

     SECTION XI.11. Confidentiality. The Agents and the Lenders agree to keep
confidential (and to cause their respective officers, directors, employees,
agents and representatives to keep confidential) all information, materials and
documents furnished to the Agents or any Lender (the "Information").
Notwithstanding the foregoing, the Agents and each Lender shall be permitted to
disclose Information (i) to such of its officers, directors, employees, agents
and representatives as need to know such Information in connection with its
participation in any of the Transactions or the administration of this Agreement
or the other Loan Documents; (ii) to the extent required by applicable laws and
regulations or by any subpoena or similar legal process, or requested by any
governmental agency or authority; (iii) to the extent such Information (A)

subsidiaries; (iv) to the extent any Loan Party or any of its subsidiaries shall
have consented to such disclosure in writing; (v) in connection with the sale of
any Collateral pursuant to the provisions of any of the other Loan Documents; or
(vi) pursuant to Section 11.03(g) hereof.

     SECTION XI.12. Submission to Jurisdiction. (a) Any legal action or
proceeding with respect to this Agreement or the Notes or any other Loan
Document may be brought in the courts of the State of California or of the
United States of America for the Northern District of California, and, by
execution and delivery of this 


                                      104

Agreement, each Loan Party hereby accepts for itself and in respect of its
property, generally and unconditionally, the jurisdiction of the aforesaid
courts.

     (b) Each Loan Party hereby irrevocably waives, in connection with any such
action or proceeding, any objection, including, without limitation, any
objection to the laying of venue or based on the grounds of forum non

action or proceeding in such jurisdictions.

XII.     GUARANTEES

     Each Guarantor unconditionally guarantees, as a primary obligor and not
merely as a surety, jointly and severally with each other Guarantor, the due and
punctual payment of the principal of and interest on each of the Notes, when and
as due, whether at maturity, by acceleration, by notice of prepayment or
otherwise, and the due and punctual performance of all other Obligations. Each
Guarantor further agrees that the Obligations may be extended and renewed, in
whole or in part, without notice to or further assent from it, and that it will
remain bound upon its guarantee notwithstanding any extension or renewal of any
Obligations.

                  Each Guarantor waives presentment to, demand of payment from
and protest to the Borrowers of any of the Obligations, and also waives notice
of 


                                      105
<PAGE>


acceptance of its guarantee and notice of protest for nonpayment. The
obligations of a Guarantor hereunder shall not be affected by (a) the failure of
any Lender or the Administrative Agent to assert any claim or demand or to
enforce any right or remedy against the Borrowers or any other Guarantor under
the provisions of this Agreement, the Notes or any of the other Loan Documents
or otherwise; (b) any rescission, waiver, amendment or modification of any of
the terms or provisions of this Agreement, the Notes, any of the other Loan
Documents, any guarantee or any other agreement; (c) the release of any security
held by the Administrative Agent for the Obligations or any of them; or (d) the
failure of any Lender to exercise any right or remedy against any other
Guarantor of the Obligations.

     Each Guarantor further agrees that its guarantee constitutes a guarantee of
payment when due and not of collection, and waives any right to require that any
resort be had by any Lender to any security (including, without limitation, any
Collateral) held for payment of the Obligations or to any balance of any deposit
account or credit on the books of any Lender in favor of any of the Borrowers or
any other person.

     The obligations of each Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including,
without limitation, any claim of waiver, release, surrender, alteration or
compromise, and shall not be subject to any defense or setoff, counterclaim,
recoupment or termination whatsoever by reason of the invalidity, illegality or
unenforceability of the Obligations or otherwise. Without limiting the
generality of the foregoing, the obligations of each Guarantor hereunder shall
not be discharged or impaired or otherwise affected by the failure of the
Administrative Agent or any Lender to assert any claim or demand or to enforce
any remedy under this Agreement, the Notes or under any other Loan Document, any
guarantee or any other agreement, by any waiver or modification of any provision
thereof, by any default, failure or delay, willful or otherwise, in the
performance of the Obligations, or by any other act or omission which may or
might in any manner or to any extent vary the risk of such Guarantor or
otherwise operate as a discharge of such Guarantor as a matter of law or equity.

     Each Guarantor further agrees that its guarantee shall continue to be
effective or be reinstated, as the case may be, if at any time payment, or any
part thereof, of principal of or interest on any Obligation is rescinded or must
otherwise be returned by the Administrative Agent or any Lender upon the
bankruptcy or reorganization of any of the Borrowers or otherwise.

                  Each of the Guarantors irrevocably waives acceptance hereof,
presentment, demand, notices of nonperformance, protests, notices of protest,
notices of dishonor, and notices of acceptance of this guarantee and of the
existence, creation, or incurring of new or additional Obligations and any
notice not provided for herein, as well as any requirement that at any time any
action be taken by any person against the Borrowers or any other person or any
collateral. Each of the Guarantors waives any 


                                      106
<PAGE>


defense arising by reason of any disability or other defense of the Borrowers,
or the cessation from any cause whatsoever of the liability of the Borrowers, or
any claim that the obligations of such Guarantor exceed or are more burdensome
than those of the Borrowers. Each of the Guarantors waives any rights and
defenses that are or may become available to such Guarantor by reason of
Sections 2787 to 2855, inclusive, of the California Civil Code. Each of the
Guarantors waives all rights and defenses that such Guarantor may have because
any of the Obligations is secured by real property. This means, among other
things: (i) the Administrative Agent or any Lender may collect from any of the
Guarantors without first foreclosing on any real or personal property collateral
pledged by the Borrowers; and (ii) if the Administrative Agent forecloses on any
real property collateral pledged by the Borrowers: (1) the amount of the
Obligations may be reduced only by the price for which that collateral is sold
at the foreclosure sale, even if the collateral is worth more than the sale
price, and (2) the Administrative Agent may collect from each or any of the
Guarantors even if the Administrative Agent, by foreclosing on the real property
collateral, has destroyed any right such Guarantor may have to collect from the
Borrowers. This is an unconditional and irrevocable waiver of any rights and
defenses each of the Guarantors may have because any of the Obligations is
secured by real property. These rights and defenses include, but are not limited
to, any rights or defenses based upon Section 580a, 580b, 580d, or 726 of the
California Code of Civil Procedure. Each of the Guarantors waives any right or
defense it may have at law or equity, including California Code of Civil
Procedure Section 580a, to a fair market value hearing or action to determine a
deficiency judgment after a foreclosure. No provision or waiver herein shall be
construed as limiting the generality of any other waiver contained herein.

     Each of the Guarantors authorizes the Administrative Agent or any Lender,
without notice or demand and without affecting the liability of each of the
Guarantors hereunder, from time to time, either before or after revocation
hereof, to (a) receive and hold security for the payment of this guarantee or
any of the Obligations, and exchange, enforce, waive, release, fail to perfect,
sell, or otherwise dispose of any such security; (b) apply such security and
direct the order or manner of sale thereof as the Administrative Agent or any
Lender in its discretion may determine; and (c) release or substitute any one or
more of the endorsers or guarantors.

     Notwithstanding any payment made by or for the account of any of the
Guarantors pursuant hereto, no Guarantor shall be subrogated to any right of the
Administrative Agent or any Lender until such time as the Administrative Agent
shall have received final payment of the full amount of all Obligations. Until
the Obligations shall have been paid in full, even though the Obligations are in
excess of the liability of any Guarantor hereunder, such Guarantor waives (a)
any right of subrogation, reimbursement, indemnification, and contribution
(contractual, statutory, or otherwise) including, without limitation, any claim
or right of subrogation under the Bankruptcy Code (Title 11, United States Code)
or any successor statute, arising from the existence or performance hereof, 


                                      107
<PAGE>


(b) any right to enforce any remedy which the Administrative Agent or any Lender
now has or may hereafter have against the Borrowers, and (c) any benefit of, and
any right to participate in, any security now or hereafter held by the
Administrative Agent or any Lender. Each of the Guarantors understands and
acknowledges that if the Administrative Agent forecloses, either by judicial
foreclosure or by exercise of power of sale, any deed of trust securing the
Obligations, that foreclosure could impair or destroy any ability that such
Guarantor may have to seek reimbursement, contribution, or indemnification from
the Borrowers or others based on any right such Guarantor may have of
subrogation, reimbursement, contribution, or indemnification for any amounts
paid by such Guarantor under this guarantee. Each of the Guarantors further
understands and acknowledges that in the absence of this paragraph, such
potential impairment or destruction of such Guarantor's rights, if any, may
entitle such Guarantor to assert a defense to this guarantee based on Section
580d of the California Code of Civil Procedure as interpreted in Union Bank v.
Gradsky, 265 Cal. App. 2d. 40 (1968). By executing this agreement, each of the
Guarantors freely, irrevocably, and unconditionally: (i) waives and relinquishes
that defense and agrees that such Guarantor will be fully liable hereunder even
though the Administrative Agent may foreclose, either by judicial foreclosure or
by exercise of power of sale, any deed of trust securing the Obligations; (ii)
agrees that such Guarantor will not assert that defense in any action or
proceeding which the Administrative Agent or any Lender may commence to enforce
this agreement; (iii) acknowledges and agrees that the rights and defenses
waived by such Guarantor herein include any right or defense that such Guarantor
may have or be entitled to assert based upon or arising out of any one or more
of Sections 580a, 580b, 580d, or 726 of the California Code of Civil Procedure
or Section 2848 of the California Civil Code; and (iv) acknowledges and agrees
that the Administrative Agent and each Lender is relying on this waiver in
creating the Obligations, and that this waiver is a material part of the
consideration which the Administrative Agent and each Lender is receiving for
creating the Obligations.

     Each of the Guarantors acknowledges and agrees that it shall have the sole
responsibility for obtaining from the Borrowers such information concerning the
Borrowers's financial conditions or business operations as such Guarantor may
require, and that neither the Administrative Agent nor any Lender has any duty
at any time to disclose to such Guarantor any information relating to the
business operations or financial conditions of the Borrowers.
