                             --------------------

          This Employment Agreement ("Agreement"), made this 31st day of
December, 1996, is entered into by and between Renaissance Solutions, Inc., a
Delaware corporation with its principal place of business at Lincoln North, 55
Old Bedford Road, Lincoln, MA 01773 (the "Company"), and O. Bruce Gupton,
residing at 16 Hurlingham Drive, Conyers Farm, Greenwich, CT 06831 (the
"Employee").

          Whereas, on December 31, 1996, the Company, Artist Acquisition Corp.,
a Connecticut corporation and a wholly-owned subsidiary of the Company (the
"Transitory Subsidiary"), International Systems Services Corporation, a
Connecticut corporation ("ISS"), and the Employee as the sole stockholder of
ISS, entered into an Agreement and Plan of Merger (the "Merger Agreement"),
pursuant to which the Transitory Subsidiary will merge with and into ISS, with
ISS surviving such merger; and

          Whereas, in connection with the consummation of the transactions
contemplated by the Merger Agreement, the Company desires to employ the
Employee, and the Employee desires to be employed by the Company.

          Now, therefore, in consideration of the mutual covenants and promises
contained herein, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged by the parties hereto, the parties
agree as follows:

          1.  Term of Employment.  The Company hereby agrees to employ the
              ------------------                                          
Employee, and the Employee hereby accepts employment with the Company, upon the
terms set forth in this Agreement, for the period commencing on the Closing
Date, as such term is defined in the Merger Agreement (the "Commencement Date"),
and ending on the fourth anniversary of the Commencement Date, unless sooner
terminated in accordance with the provisions of Section 4 (such period, as it
may be extended, the "Employment Period").

Date, determine, or in such other position as the Company or its Board of
Directors (the "Board") may from time to time determine.  The Employee shall be
subject to the supervision of, and shall have such authority as is delegated to
him by, the Board or such officer or officers of the Company designated by the
Board.

the duties and responsibilities inherent in such position and such other duties
and responsibilities as the Board or its designee shall from time to time
reasonably assign to him.  The Employee agrees to devote his entire business
time, attention and energies to the business and interests of the Company during
the Employment Period; provided, however, that the Employee shall be free to

practices and policies of the Company and any changes therein which may be

          3.4  Reimbursement of Expenses.  The Company shall reimburse the
               -------------------------

     4.   Employment Termination.  The employment of the Employee by the
               ----------------------                                        
Company pursuant to this Agreement shall terminate upon the occurrence of any of
the following:

          4.1  Expiration of the Employment Period in accordance with Section 1;

          4.2  At the election of the Company, for cause, immediately upon
written notice by the Company to the Employee.  For the purposes of this Section
4.2, cause for termination shall be deemed to exist upon (a) a good faith
finding by the Company of continual failure of the Employee to perform his
assigned duties for the Company, or dishonesty, gross negligence or willful
misconduct related to the performance of the Employee's duties for the Company;
(b) the conviction of the Employee of, or the entry of a pleading of guilty or
nolo contendere by the Employee to, any crime involving moral turpitude or any
felony; (c) Employee's habitual drunkenness, or the use, possession,
distribution or being under the influence of alcohol or illegal substances or
drugs in the workplace or in a manner otherwise affecting the Employee's
performance of his duties for the Company (the only exception is that the
Employee may consume alcohol reasonably and responsibly, if he so chooses, at
legitimate business events and functions where alcohol is legally available); or
(d) the material breach by the Employee of any terms of this Agreement, which
breach continues for 30 days subsequent to written notice from the Company to
the Employee of the breach (unless such breach is not susceptible to cure, in
which case termination shall be deemed to be immediate);

          4.3  Upon the death or disability of the Employee.  As used in this
Agreement, the term "disability" shall mean the inability of the Employee, due
to a physical or mental disability, for a period of 120 days, whether or not
consecutive, during any 360-day period to perform the services contemplated
under this Agreement.  A determination of disability shall be made by a
physician satisfactory to both the Employee and the Company; provided that if
                                                             -------- ----   
the Employee and the Company do not agree on a physician, the Employee and the
Company shall each select a physician and such physicians together shall select
a third physician, whose determination as to disability shall be binding on all
parties; or

          4.4  At the election of the Company or the Employee, upon not less
than 30 days' prior written notice of termination.

     5.   Effect of Termination.
          --------------------- 

          5.1  Termination for Cause or Voluntary Termination.  In the event the
               ----------------------------------------------                   
Employee's employment is terminated by the Company for cause pursuant to Section
4.2, or by the Employee pursuant to Section 4.4, the Company shall pay to the

                                      -3-
<PAGE>
 
Employee the compensation and benefits which would otherwise be payable to him
through the last day of his actual employment by the Company.

          5.2  Termination for Death or Disability.  If the Employee's
               -----------------------------------                    
employment is terminated by death or because of disability pursuant to Section
4.3, the Company shall pay to the estate of the Employee or to the Employee, as
the case may be, the compensation and benefits which would otherwise be payable
to the Employee through the date of his termination of employment because of
death or disability.

          5.3  Termination Without Cause.  If the Employee's employment is
               -------------------------                                  
terminated at the election of the Company pursuant to Section 4.4, the Company
shall pay to the Employee the base salary and benefits payable to him under
Section 3, at the times provided in Section 3, including the pro rata portion of
any bonuses earned under Section 3.2 during the then current one-year period of
the Employment Period, through the day immediately prior to the one-year
anniversary of the date of his termination of employment.

          5.4  Survival. The provisions of Sections 5 and 6 shall survive the
               --------
termination of this Agreement.

     6.   Non-competition and Non-Solicitation
          ------------------------------------

          6.1  Non-competition.  During the Non-Competition Period (as defined
               ---------------                                                
below) the Employee will not directly or indirectly:

               (A)  as an individual proprietor, partner, stockholder, officer,
          employee, director, joint venturer, investor, lender, consultant, or
          in any other capacity whatsoever (other than as the holder of not more
          than one percent of the combined voting power of the outstanding stock
          of a publicly held company), develop, design, produce, market, sell or
          render (or assist any other person in developing, designing,
          producing, marketing, selling or rendering) products or services
          competitive with those developed, designed, produced, marketed, sold
          or rendered by the Company or any subsidiary of the Company (whether
          existing now or hereafter acquired or established) (a "Subsidiary")
          while the Employee was employed by the Company; provided, however,
                                                          --------  -------
          that nothing herein shall prohibit the Employee from holding up to 3%
          of the publicly-traded securities of any corporation; or

               (B) solicit, divert or take away, or attempt to divert or to take
          away, the business or patronage of any of the clients, customers or
          accounts, or prospective clients, customers or accounts, of the
          Company 

                                      -4-
<PAGE>
 
          or any of its Subsidiaries which were contracted, solicited or served
          by the Employee while employed by the Company.

          The term Non-Competition Period means the period of time commencing on
the Commencement Date and ending on (a) the first anniversary of the termination
or cessation of the Employee's employment, if such termination or cessation
occurs under Sections 4.1 or 4.3 or under Section 4.4 at the election of the
Company, and (b) the later of (i) the fourth anniversary of the Commencement
Date, and (ii) the first anniversary of the termination or cessation of the
Employee's employment, if such termination or cessation occurs under Section 4.2
or under Section 4.4 at the election of the Employee.

          6.2  Non-solicitation.  While the Employee is employed by the Company
               ----------------                                                
and for a period of one year after the termination or cessation of such
employment for any reason, the Employee will not directly or indirectly recruit,
solicit or hire or otherwise retain the services of any employee of the Company
or of any of its Subsidiaries, or induce or attempt to induce any employee of
the Company or any of its Subsidiaries to terminate his/her employment with, or
otherwise cease his/her relationship with, the Company or such Subsidiary.

          6.3  Interpretation.  If any restriction set forth in Sections 6.1 or
               --------------                                                  
6.2 is found by any court of competent jurisdiction to be unenforceable because
it extends for too long a period of time or over too great a range of activities
or in too broad a geographic area, it shall be interpreted to extend only over
the maximum period of time, range of activities or geographic area as to which
it may be enforceable.

          6.4  Equitable Remedies.  The restrictions contained in this Section 6
               ------------------                                               
are necessary for the protection of the business and goodwill of the Company and
are considered by the Employee to be reasonable for such purpose.  The Employee
agrees that any breach of this Section 6 is likely to cause the Company
substantial and irrevocable damage and therefore, in the event of any such
breach, the Employee agrees that the Company, in addition to such other remedies
which may be available, shall be entitled to specific performance and other
injunctive relief.

     7.   Proprietary Information and Developments.  Concurrently with the
          ----------------------------------------

disclosure Agreement, a copy of which is attached hereto as Exhibit B (the "Non-

provision of this Agreement.

    15.   Miscellaneous.
          -------------

under this Agreement shall operate as a waiver of that or any other right.  A

                                                                       ---------

                     INVENTION AND NON-DISCLOSURE AGREEMENT
                     --------------------------------------


     This Agreement is made between BUYER, a Delaware corporation (hereinafter
referred to collectively with its subsidiaries as the "Company"), and O. Bruce
Gupton (the "Employee").

     In consideration of the employment or the continued employment of the
Employee by the Company, the Company and the Employee agree as follows:

1.   Proprietary Information.
     ----------------------- 

     (a)  The Employee agrees that all information, whether or not in writing,
of a private, secret or confidential nature concerning the Company's business,
business relationships or financial affairs (collectively, "Proprietary
Information") is and shall be the exclusive property of the Company. By way of
illustration, but not limitation, Proprietary Information may include
inventions, products, processes, methods, techniques, formulas, compositions,
compounds, projects, developments, plans, research data, clinical data,
financial data, personnel data, computer programs, customer and supplier lists,
and contacts at or knowledge of customers or prospective customers of the
Company. The Employee will not disclose any Proprietary Information to any
person or entity other than employees of the Company or use the same for any
purposes (other than in the performance of his duties as an employee of the
Company) without written approval by an officer of the Company, either during or
after his employment with the Company, unless and until such Proprietary
Information has become public knowledge without fault by the Employee.

     (b)  The Employee agrees that all files, letters, memoranda, reports,
records, data, sketches, drawings, laboratory notebooks, program listings, or
other written, photographic, or other tangible material containing Proprietary
Information, whether created by the Employee or others, which shall come into
his custody or possession, shall be and are the exclusive property of the
Company to be used by the Employee only in the performance of his duties for the
Company. All such materials or copies thereof and all tangible property of the
Company in the custody or possession of the Employee shall be delivered to the
Company, upon the earlier of (i) a request by the Company or (ii) termination of
his employment. After such delivery, the Employee shall not retain any such
materials or copies thereof or any such tangible property.


     (c)  The Employee agrees that his obligation not to disclose or to use
information and materials of the types set forth in paragraphs (a) and (b)
above, and 

                                      -1-
<PAGE>
 
his obligation to return materials and tangible property, set forth in paragraph
(b) above, also extends to such types of information, materials and tangible
property of customers of the Company or suppliers to the Company or other third
parties who may have disclosed or entrusted the same to the Company or to the
Employee.

2.   Developments.
     ------------ 

     (a)  The Employee will make full and prompt disclosure to the Company
of all inventions, improvements, discoveries, methods, developments, software,
and works of authorship, whether patentable or not, which are created, made,
conceived or reduced to practice by him or under his direction or jointly with
others during his employment by the Company, whether or not during normal
working hours or on the premises of the Company (all of which are collectively
referred to in this Agreement as "Developments").

     (b)  The Employee agrees to assign and does hereby assign to the Company
(or any person or entity designated by the Company) all his right, title and
interest in and to all Developments and all related patents, patent
applications, copyrights and copyright applications. However, this paragraph
2(b) shall not apply to Developments which do not relate to the present or
planned business or research and development of the Company and which are made
and conceived by the Employee not during normal working hours, not on the
Company's premises and not using the Company's tools, devices, equipment or
Proprietary Information. The Employee understands that, to the extent this
Agreement shall be construed in accordance with the laws of any state which

agencies thereof, which impose obligations or restrictions on the Company
regarding inventions made during the course of work under such agreements or
regarding the confidential nature of such work. The Employee agrees to be bound
by all such obligations and restrictions which are made known to the Employee
and to take all action necessary to discharge the obligations of the Company
under such agreements.

other occasion.

this Agreement for the benefit of the Company or any subsidiary or affiliate
