                    EMPLOYMENT AND NONCOMPETITION AGREEMENT
                    ---------------------------------------

     This agreement is made effective October 21, 1998, between American Dental
Partners, Inc., a Delaware corporation (the "Company"), and Lee S. Feldman (the
"Employee"), who hereby agree as follows:

     (S)1. Employment. Upon the terms and subject to the conditions described in
           ----------       
this agreement, the Company hereby employs the Employee and the Employee hereby
accepts employment by the Company.

     (S)2. Term.  The Employee's employment with the Company pursuant to this
           ----                                                              
agreement shall be for the period beginning on November 16, 1998 (the
"Commencement Date") and ending on the third anniversary of the Commencement
Date (the "Initial Term"), unless sooner terminated pursuant to 8 of this
agreement.  This agreement may be extended or renewed after the expiration of
the Initial Term, but only by mutual written agreement of the Parties.  When
permitted by the context, any reference in this agreement to the "term of this
agreement" shall include the Initial Term and the period of any such extensions
or renewals.

     (S)3. Services. The Employee shall serve as Vice President, General Counsel
           --------     
of the Company, shall report directly to the Chief Executive Officer of the
Company (the "CEO), and shall devote his full business and professional time,
attention, energy, loyalty, and skill to the Company's business, performing such
executive or administrative tasks and having such responsibilities as may be
assigned to him from time to time by the CEO or the Board of Directors of the
Company (the "Board").

     (S)4. Compensation.  As compensation for his services under this agreement,
           ------------                                                         
the Company shall pay the Employee a base salary at the annual rate of $130,000
(the "Base Salary"), payable in bi-weekly installments, in arrears, and in
accordance with the Company's general policies and procedures for payment of
salaries to its executive personnel.  The Employee's performance shall be
reviewed not less often than annually for the purpose, among others, of
considering potential increases in the Base Salary, but the Company shall not be
obligated to make any such increases.

     In addition, the Employee may earn an annual bonus for each calendar year
during the term of this agreement, beginning with calendar year 1999, in an
amount up to 25% of the Base Salary (as in effect from time to time), which
bonus shall be based upon and tied to the achievement of various objectives to
be prepared annually by the CEO.  For the first full calendar year of the
Initial Term, the Employee shall in fact be paid a bonus equal to 25% of his
Base Salary so long as the Employee remains employed for such full year and has
not received written notice of a Performance Failure as set forth in 8(i)(B) of
this agreement.  Any such annual bonuses earned shall be paid in cash.

the Employee shall also be entitled to the following fringe benefits and

           (c)  Participation in such stock option plans of the Company as may

     to all terms and conditions of such plans; and

           (d)  Such other benefits and perquisites as may be offered generally
     to the Company's executive personnel from time to time pursuant to such
     terms, conditions, and policies as may be approved by the Board.

     (S)6. Initial Stock Option.  As additional consideration for the Employee's

     Company"), or interfere or attempt to interfere with any relationship of
     any Affiliated Company with any Restricted Company;

          (c)  Induce or encourage any employee, officer, director, agent,

     which would tend to disparage or diminish the reputation of any Affiliated

     For purposes of this agreement:

     month period immediately preceding the Termination Date.

     The Employee acknowledges that (1) the provisions of this section are
fundamental and essential for the protection of the Company's legitimate
business and proprietary interests, (2) such provisions are reasonable and
appropriate in all respects, and (3) in the event of any violation by the
Employee of any of such provisions, the Company would suffer irreparable harm
and its remedies at law would be inadequate.  In the event of any violation or
attempted violation of such provisions by the Employee, the Company shall be
entitled to a temporary restraining order, temporary and permanent injunctions,
specific performance, and other equitable relief, without any showing of
irreparable harm or damage or the posting of any bond, in addition to any other
rights or remedies which may then be available to the Company.

     (S)8. Termination.  The Employee's employment with the Company shall
           -----------

     (b)   At any time when the Employee is under a Long-Term Disability

     (c)   At any time without Cause; provided that if the Company terminates
the Employee's employment pursuant to this clause (c) and no other basis for
termination exists under this agreement, then the Employee shall be entitled to
severance payments in an aggregate amount equal to the Base Salary for a period
of one year. Any such severance payments shall be payable periodically in the
same manner as the Base Salary is payable under 4 of this agreement, and,
notwithstanding any other provisions of this agreement to the contrary, such
severance payments shall be payable only so long as the Employee is in full
compliance with the provisions of 7 of this agreement.

such Performance Failure promptly following written notice from the Company to
do so; or

            (C)  having corrected (or the Company having waived the correction
of) a Performance Failure, the occurrence of any subsequent Performance Failure;
and

mental incapacity, it is more likely than not that the Employee will be unable,
within 180 days after such incapacity commenced, to perform the essential
functions of his position with the Company, with or without reasonable
accommodation. In the event of any disagreement about whether or when the
Employee is under a Long-Term Disability, the question shall be determined: (A)
by a physician selected by agreement between the Employee and the Company if
such a physician is selected within 10 days after either of them requests the
other so to agree; or, if not, (B) by two physicians, the first of whom shall be
selected by the Employee and the second of whom shall be selected by the Company
or, if the Employee fails to make a selection within 10 days after being
requested to do so by the Company, the second physician shall be selected by the
first physician; or, if the two physicians fail to agree, (C) by a third
physician selected by the first two physicians. The Employee shall submit to all
reasonable examinations requested by any such physicians.

     (S)9.  Capacity.  The Employee represents and warrants to the Company that

may be available to that Party from time to time, whether under any other
agreement, at law, or in equity.

Company (for any reason) shall not relieve either Party of any of that Party's
obligations under this agreement existing at, arising as a result of, or
relating to acts or omissions occurring prior to, such termination.  Without
limiting the generality of the preceding sentence, in no event shall the
termination of such employment modify or affect any obligations of the Employee
or rights of the Company under 7 of this agreement, all of which shall survive
the termination of such employment.

     (S)12. Notices.  All notices and other communications under this agreement
           -------          
to either Party shall be in writing and shall be deemed given when delivered
