                              EMPLOYMENT AGREEMENT

         This Employment Agreement ("Agreement") is made as of November 13,
1997 by and between Masters, Inc., (the "Company"), a Maryland corporation and

("GroupMAC"), and Ronald D. Bryant, an individual resident of the State of
Maryland ("Employee").

         1. Employment. The Company hereby agrees to employ the Employee and
the Employee hereby agrees to work for the Company upon the terms and
conditions set forth herein.

         2. Term of Employment. This Agreement shall continue in effect for an
initial term of three (3) years from the date of this Agreement and may

the Company and the Employee, unless terminated in accordance with Section 6.

         3. Scope of Duties; Representations and Warranties.

            (a) The Employee will have such duties as are assigned or delegated
to the Employee by the Board of Directors of the Company and will initially
serve as the President of the Company. The Employee will devote his entire
business time, attention, skills, and energy exclusively to the business of the
Company, and will use his best efforts to promote the success of the Company's
business, and will cooperate fully with the Board of Directors in the
advancement of the best interests of the Company. If the Employee is elected as
a director of the Company or as a director or officer of any of its affiliates,
the Employee will fulfill his duties as such director or officer without
additional compensation.

            (b) The Employee represents and warrants that the execution and
delivery by the Employee of this Agreement do not, and the performance by the
Employee of the Employee's obligations hereunder will not, with or without the
giving of notice or the passage of time, or both: (i) violate any judgment,
writ, injunction, or order of any court, arbitrator, or governmental agency
applicable to the Employee, (ii) conflict with, result in the breach of any
provisions of or the termination of, or constitute a default under, any
agreement to which the Employee is a party or by which the Employee is or may
be bound.

         4. Compensation.

            (a) The Company shall initially pay the Employee an annual base
salary of $150,000, subject to adjustment as provided below, which will be
payable in equal periodic

installments according to the Company's customary payroll practices, but no
less frequently than monthly. Employee's base salary will be reviewed by the
Board of Directors of the Company not less frequently than annually, and may be
adjusted upward or downward in the sole discretion of the Board of Directors of
the Company, but in no event will Employee's base salary be less than $150,000
per year. The Company agrees to provide a vehicle comparable to the Employee's
present vehicle and all reasonable costs associated therewith for maintenance,
gasoline and insurance.

            (b) All payments of salary and other compensation to the Employee
shall be made after deduction of any taxes and other amounts which are required
to be withheld with respect thereto under applicable federal and state laws.

         5. Fringe Benefits; Expenses.

            (a) So long as the Employee is employed by the Company, the
Employee shall participate in all employee benefit plans sponsored by the
Company for its executive employees, including but not limited to vacation
policy, sick leave and disability leave, life insurance, health insurance,
dental insurance, and stock ownership and/or profit sharing plans; provided,
however, that the nature, amount and limitations of such plans shall be
determined from time to time by the Board of Directors of the Company.

            (b) The Company shall pay the Employee for all reasonable business
expenses incurred by the Employee in the scope of his employment; provided,
however, that the Employee must file expense reports with respect to such
expenses in accordance with the Company's policies as are in effect from time
to time.

            (c) The Employee shall be entitled to a minimum of 4 weeks paid
vacation in accordance with the vacation policies of the Company in effect from
time to time. The Employee will also be entitled to the paid holidays and other
paid leave set forth in the Company's policies. Vacation days earned during any
calendar year that are not used by the Employee by the end of the following
calendar year will be forfeited.

         6. Termination. Employee agrees that this Agreement may be terminated
by the Company with or without "Cause" at any time, subject to the terms of
this Section 6. Such termination shall be effective upon delivery of written
notice to Employee of the Company's election to terminate this Agreement under
this Section 6.

            (a) Definition of "Cause". When used in connection with the
termination of employment with the Company, "Cause" shall mean: (i) Employee's
breach of his obligations under this Agreement; (ii) Employee's failure to
adhere to any written Company policy after the Employee has been given a
reasonable opportunity to comply with such policy or cure his failure to
comply; (iii) the conviction of or the entering of a guilty plea or plea of no
contest with respect to, a felony, the equivalent thereof, or any other crime
which results in Employee's imprisonment if such imprisonment effects
Employee's performance hereunder; (iv) the commission by the Employee of an act
of fraud upon the Company or any of its affiliates; (v) the misappropriation
(or attempted

                                      -2-

<PAGE>   3


misappropriation) or any funds or property of the Company or any of its
affiliates by the Employee; (vi) the failure by the Employee to perform duties
assigned to him after reasonable notice and opportunity to cure such
performance; (vii) the engagement by the Employee in any direct, material
conflict of interest with the Company without compliance with the Company's
conflict of interest policy, if any, then in effect; (viii) the engagement by
the Employee, without the written approval of the Board of Directors of the
Company, in any activity which competes with the business of the Company or any
of its affiliates or which would result in a material injury to the Company or
any of its affiliates; (ix) the engagement by the Employee in any activity
which would constitute a material violation of the provisions of the Company's
or GroupMAC's Insider Trading Policy or Business Ethics Policy, if any, then in
effect, or (x) the failure by the Employee to sign any lock-up letters,
standstill agreements, or other similar documentation required by an
underwriter in connection with a public offering of securities by the Company
or GroupMAC or to take other actions reasonably related thereto as requested by
the Board of Directors of the Company.

            (b) Termination for Cause or Resignation. If the Company terminates
Employee's employment for Cause or the Employee voluntarily resigns, the
Company shall pay the Employee's base salary earned through the date of
termination, but all rights to any other compensation or benefits arising
hereunder shall be canceled and terminated in all respects concurrently with
such termination of employment; provided that Employee may elect to continue to
participate, at Employee's own expense, in such health insurance and other
benefits as to which the opportunity for continuing participation is mandated
by applicable laws.

            (c) Termination Without Cause. In the event that the Employee's
employment is terminated by the Company without Cause, the Company shall,
subject to the terms of subsections (d) and (e) of this Section 6 below, and
only if and as long as Employee is not in breach of his obligations under this
Agreement, (i) pay to the Employee an amount equal to 12 months compensation at
his then current base salary payable in a lump sum, (ii) continue to provide
benefits in the kind and amounts provided up to the date of termination for
such 12 month period, including continuation of any Company-paid benefits as
described in Section 5 for Employee and his family.

            (d) Disability; Death. If at any time during the term of this
Agreement, Employee is unable due to physical or mental disability to perform
effectively his duties hereunder, the Company shall continue payment of
compensation as provided in Section 4 during the first 12 months of such
disability to the extent not covered by the Company's disability insurance
policies. Upon the expiration of such 12-month period, the Company, at its sole
option, may continue payment of Employee's salary for such additional periods
as the Company elects, or may terminate this Agreement without further
obligations hereunder. If Employee should die during the term of this
Agreement, Employee's employment and the Company's obligations hereunder shall
terminate as of the end of the month in which Employee's death occurs and there
will be no salary and benefit continuation period.

            (e) Securities Matters. Employee agrees that he will sign any
lock-up letters, standstill agreements, or other similar documentation required
by an underwriter in connection with a public offering of securities by the
Company or GroupMAC, or take other actions reasonably

                                      -3-

<PAGE>   4


related thereto as requested by the Board of Directors of the Company. Failure
to take any such action shall be "Cause" for termination, or if termination has
already occurred, shall cause Employee to forfeit any further rights to the
salary continuation or other payments that would otherwise be payable to
Employee. In addition, Employee agrees that in such event the Company can seek
and obtain specific performance of such covenant, including any injunction
requiring execution of such documents and the taking of such actions, and the
Employee hereby appoints the then current president of the Company to sign any
such documents on his behalf so long as such documents are prepared on the same
basis as other management shareholders generally.

            (f) Waiver and Release. In the event that employment is terminated
by the Company without Cause, Employee agrees to accept, in full settlement of
any and all claims, losses, damages and other demands which Employee may have
arising out of such termination, as liquidated damages and not as a penalty,
the applicable amounts payable to Employee as set forth in this Section 6.
Employee hereby waives any and all rights he may have to bring any cause of
action or proceeding contesting any termination without Cause. Under no
circumstances shall Employee be entitled to any compensation or confirmation of
any benefits under this Agreement for any period of time following his date of
termination if his termination is for Cause.

         7. Covenant Not to Compete.

            (a) During the term of this Agreement, Employee will not compete
with the Company or its affiliates, directly or indirectly, either for himself
or as a member of a partnership or as a stockholder (except as a stockholder of
less than one percent (1%) of the issued and outstanding stock of a
publicly-held company whose gross assets exceed one hundred million dollars),
investor, owner, officer or director of a company or other entity, or as an
employee, agent, associate or consultant of any person, partnership,
corporation or other entity, in any business in competition with that carried
on by the Company or its affiliates.

            (b) Employee further agrees that, for the period from the date
hereof to the later to occur of (i) five (5) years after the date hereof or
(ii) two (2) years from and after the date of termination of Employee's
employment under this Agreement, regardless of the reason for such termination,
he will neither represent any other company nor engage in or carry on (directly
or indirectly, either for himself or as a member of a partnership or as a
stockholder (other than as a stockholder of less than one percent (1%) of the
issued and outstanding stock of a publicly-held company whose gross assets
exceed one hundred million dollars), investor, owner, officer or director of a
company or other entity, or as an employee, agent, associate or consultant of
any person, partnership, corporation or other entity) any business which
engages in the installation, construction or maintenance of heating,
ventilation, air conditioning systems, fire sprinklers or plumbing within a 100
mile radius of Gaithersburg, Maryland. Notwithstanding the foregoing, nothing
herein shall prevent Employee from working in the indoor air quality, heating,
ventilation and air conditioning, plumbing or electrical contracting
industries, provided that such activities are in areas not in direct
competition with any services or products produced, sold, conducted, developed,
or in the process of development by the Company or its affiliates on the date
of termination of Employee's employment.

            (c) Employee agrees that the limitations set forth herein on his
rights to compete with the Company and its affiliates are reasonable and
necessary for the protection of the Company and its affiliates. In this regard,
Employee specifically agrees that the limitations as to period of time and
geographic area, as well as all other restrictions on his activities specified
herein, are reasonable and necessary for the protection of the Company and its
affiliates. Employee agrees that, in the event that the provisions of this
Agreement should ever be deemed to exceed the scope of business, time or
geographic limitations permitted by applicable law, such provisions shall be
and are hereby reformed to the maximum scope of business, time or geographic
limitations permitted by applicable law.

            (d) Employee agrees that the remedy at law for any breach by him of
this Section 7 will be inadequate and that the Company shall also be entitled
to injunctive relief.

         8. Confidential Information and Results of Service. Employee agrees
that during the term of this Agreement, and for five (5) years after his
termination of employment, he will not make use of or disclose, without the
prior consent of the Company, Confidential Information (as hereinafter defined)
relating to the Company, or any of its affiliates, and further agrees that he
will return to the Company at the termination of the Employee's employment or
at any other time at the Company's request all written materials in his
possession embodying such Confidential Information. For purposes of this
Agreement, "Confidential Information" includes information conveyed or assigned
to the Company by Employee or conceived, compiled, created, developed,
discovered or obtained by Employee from and during his employment relationship
with the Company, whether solely by the Employee or jointly with others, which
concerns the affairs of the Company or its affiliates and which the Company
could reasonably be expected to desire be held in confidence, or the disclosure
of which would likely be embarrassing, detrimental or disadvantageous to the
Company or its affiliates and without limiting the generality of the foregoing,
such information includes information relating to inventions, and the trade
secrets, technologies, algorithms, products, services, finances, business
plans, marketing plans, legal affairs, supplier lists, client lists, potential
clients, business prospects, business opportunities, personnel assignments,
contracts and assets of the Company and information made available to the
Company by other parties under a confidential relationship. Confidential
Information, however, shall not include information (i) which is, at the time
in question, in the public domain through no wrongful act of Employee, (ii)
which is later disclosed to Employee by one not under obligations of
confidentiality to the Company or Employee, (iii) which is required by court or
governmental order, law or regulation to be disclosed, or (iv) which the
Company has expressly given Employee the right to disclose pursuant to written
agreement. Employee agrees that the remedy at law for any breach by him of this
Section 8 will be inadequate and that the Company shall also be entitled to
injunctive relief.

         9. Employee Inventions. Each Employee Invention (as defined below)
will belong exclusively to the Company. The Employee acknowledges that all of
the Employee's writing, works of authorship, specially commissioned works, and
other Employee Inventions are works made for hire and the property of the
Company, including any copyrights, patents, or other intellectual property
rights pertaining thereto. If it is determined that any such works are not
works made for hire, the Employee hereby assigns to the Company all of the
Employee's right, title, and interest,

                                      -5-

<PAGE>   6


including all rights of copyright, patent, and other intellectual property
rights, to or in such Employee Inventions. The Employee covenants that he will
promptly:

              (a) disclose to the Company in writing any Employee Invention;

              (b) assign to the Company or to a party designated by the
                  Company, at the Company's request and without additional
                  compensation, all of the Employee's right to the Employee
                  Invention for the United States and all foreign
                  jurisdictions;

              (c) execute and deliver to the Company such applications,
                  assignments, and other documents as the Company may request
                  in order to apply for and obtain patents or other
                  registrations with respect to any Employee Invention in the
                  United States and any foreign jurisdictions;

              (d) sign all other papers necessary to carry out the above
                  obligations; and

              (e) give testimony and render any other assistance but without
                  expense to the Employee in support of the Company's rights to
                  any Employee Invention.

         For purposes of this Agreement, "Employee Invention" means any idea,
invention, technique, modification, process, or improvement (whether patentable
or not), any industrial design (whether registerable or not), any mask work,
however fixed or encoded, that is suitable to be fixed or programmed in a
semiconductor product (whether recordable or not), and any work of authorship
(whether or not copyright protection may be obtained for it) created,
conceived, developed, purchased or acquired by Employee, either solely or in
conjunction with others, during the term of Employee's employment with the
Company that relates in any way to, or is useful in any manner in, the business
then being conducted or proposed to be conducted by the Company, and any such
item created by the Employee, either solely or in conjunction with others,
following termination of the Employee's employment with the Company, that is
based upon or uses Confidential Information.

operations, products or services without Employee's written consent.

termination of the Employee's employment hereunder in accordance with their

             (b) No failure on the part of any party to exercise, and no delay
in exercising, any right or remedy hereunder shall operate as a waiver hereof,
nor shall any single or partial exercise of any such right or remedy by such
party preclude any other or further exercise thereof or the exercise of any
other right or remedy. All rights and remedies hereunder are cumulative and are
in addition to all other rights and remedies provided by law, agreement or
otherwise.

             (c) The Employee's obligations to the Company and the Company's
rights and remedies hereunder are in addition to all other obligations of the
Employee and rights and remedies of the Company created pursuant to any other
agreement.

         17. Construction. Each party to this Agreement has had the opportunity
to review this Agreement with legal counsel. This Agreement shall not be
construed or interpreted against any party on the basis that such party drafted
or authored a particular provision, parts of or the entirety of this Agreement.

         18. Severability. In the event that any provision or provisions of
this Agreement is held to be invalid, illegal or unenforceable by any court of
law or otherwise, the remaining provisions of this Agreement shall nevertheless

unenforceable parts had not been included therein. In addition, in such event
the parties hereto shall negotiate in good faith to modify this Agreement so as
to effect the original intent of the parties as closely as possible with
respect to those provisions which were held to be invalid, illegal or
unenforceable.

Agreement effective as of the date first above written.
