(1)      Includes $14,100 and $12,900, which represents the dollar value of the
         benefit of premiums paid by the Company under split dollar life
         insurance arrangements for Dr. Terek Diasti and Dr. Adam Diasti,
         respectively, based on the amount of the premium attributable to the
         term insurance portion of the policies, and $26,349 and $40,078, which
         represents the present value to Dr. Terek Diasti and Dr. Adam Diasti,
         respectively, of premiums paid by the Company under such arrangements
         based on the amount of the premium attributable to the whole life
         insurance portion of the policies. The present value was calculated as
         an interest free loan of the whole life portion of the premium based on
         their respective life expectancies.
(2)      Dr. Adam Diasti, because of his obligations to the Coast P.A., agreed
         to devote such time and attention as was reasonably necessary to
         fulfill his contractual obligations to the Company. During 1998,
         Dr. Diasti devoted the majority of his time and attention to the Coast
         P.A. and as such, the Company incurred only a percentage of his
         contractual compensation. However, in 1999, Dr. Diasti devoted the
         majority of his time and attention to the Company, and therefore, both
         parties agreed Dr. Diasti's contractual compensation would be incurred
         solely by the Company.
(3)      Mr. Kelly's employment by the Company was terminated as of April 13,
         2001.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         The information set forth herein briefly describes certain
relationships and related transactions since the beginning of the Company's last
fiscal year between the Company and its Directors, officers and stockholders
owning 5% or more of the Company's Common Stock. These relationships and
transactions have been and will continue to be approved by a majority of the
Company's independent Directors of the Audit Committee and will be on terms no
less favorable to the Company than those that could be obtained from
unaffiliated parties.

AGREEMENT WITH COAST P.A.

         The Company has agreements to provide dental management, services and
support to each Coast P.A. ("Services and Support Agreements"). Dr. Adam Diasti,
a Director and the President of the Company, is the sole owner of the Coast P.A.
Payments made by the Coast P.A. to the Company for management services were
approximately $45.8 million for the year ended December 31, 2000. The service
and support fees paid to the Company by the Coast P.A. have historically ranged
from 65% to 76% of the gross revenue, net of refunds and discounts, of the
dental offices managed by the Company pursuant to the Services and Support
Agreements (the "Dental Centers"). The services and support fees between the
parties may be revised from time to time based upon negotiations between the
Audit Committee and the Coast P.A. The Company pays, out of the services and
support fee, all of the operating and non-operating expenses incurred by the
Coast P.A. at the Dental Centers, except for the salaries and benefits of the
Coast P.A.


                                       7

<PAGE>   10

dentists and dental hygienists. The Audit Committee approved an adjustment to
the services and support fees in January 2001 to 67%, which was staged in
throughout the year. The service and support fees are expected to average
between 66% and 72% over the next several years.

         In addition, the fair value of stock options granted by the Company to
affiliated dental professionals employed by a Coast P.A. are charged to the
Coast P.A. and reimbursed to the Company from the Coast P.A. Upon the departure
or termination of a dental professional from a Coast P.A., any options
previously granted that are forfeited by the dental professional pursuant to the
terms of the affiliated professional benefit plan, revert to the Coast P.A. for
reissuance to new dental professionals. As a result of such forfeitures, the
Coast P.A. currently holds options to purchase 177,635 shares of the Company's
common stock at exercise prices ranging from $1.75 to $29.75.

AGREEMENT WITH DR. ADAM DIASTI

         The Company has an agreement with Dr. Adam Diasti, pursuant to which
Dr. Diasti has agreed to sell all of his shares of Coast P.A. stock to a
licensed dentist designated by the Company if certain events occur. Dr. Diasti
is a Director and President of the Company. The purchase price under the
agreement, if the certain event should occur, will be the fair market value of
Dr. Diasti's shares of the Coast P.A.'s stock.

NOTE AND ACCOUNTS RECEIVABLE FROM COAST P.A.

         The Company periodically advances funds to/from the Coast P.A. These
advances to and from the Coast P.A. are reflected on the Company's balance sheet
as a note receivable from Coast P.A. for approximately $229,000 at December 31,
2000. The receivable is non-interest bearing and is due upon demand.

         The Coast P.A. is indebted to the Company in the aggregate amount as of
December 31, 2000 of approximately $10.5 million which represents services and
support fees payable to the Company in accordance with the Services and Support
Agreements.

EDENTALDIRECT.COM AGREEMENT

         The Company entered into a Supply Agreement dated September 27, 2000
with edentaldirect.com, Inc. Tim Diasti, an affiliate of the Company, is an
officer, director and shareholder of edentaldirect.com, Inc. and brother of
Terek and Adam Diasti. The Company's officers and directors, Terek Diasti and
Adam Diasti, and its directors, Donald Millard and John Kang are also
shareholders of edentaldirect.com, Inc. Under the Supply Agreement, the Company
purchased dental products and supplies from edentaldirect.com, Inc. During 2000,
the Company paid edentaldirect.com, Inc. approximately $89,000 for dental
products and supplies. The Company believes the terms of the Supply Agreement
are at least as favorable as it could obtain from unrelated parties.

EXTRAORDINARY TRANSACTION

         During the latter part of 2000, there were discussions, negotiations
and significant professional services and fees pertaining to the possible
redemption of shares by the Company at a substantial premium to the market price
of the shares which would have resulted in a privatization of the Company with
100% ownership by an entity controlled by Dr. Terek Diasti and Dr. Adam Diasti.
The Company's interests in the matter were represented by an independent
committee of the Board of Directors made up of disinterested Directors. In late
March 2001, this transaction was abandoned due to difficulties in obtaining
financing to consummate the transaction. In connection with the discussions and
negotiations of the possible

transaction, the Company incurred approximately $800,000 of expenses, of which a
portion represented reimbursements of expenses by the proposed acquiring entity.
