              Cambridge Technology Partners (Massachusetts), Inc.

                             Terms And Conditions
1. Plan Incorporated by Reference.  This Option is issued pursuant to the terms
   -------------------------------                                             
   of the Cambridge Technology Partners (Massachusetts), Inc. 1991 Stock Option

   regarding the operation of the Plan are final and binding. Copies of the Plan

   -------------                                                            
   upon exercise of the whole or any part of this Option is the Option Price set
   forth on the face of this certificate.
3. Vesting Schedule.  No portion of this Option may be exercised until the date
   -----------------                                                           
   on which such portion shall have vested. Except as set forth herein, and
   subject to the determination of the Company in its sole discretion to
   accelerate the vesting schedule hereunder due to other circumstances and
   subject to a reduction in the percentage of Option Shares vesting each month
   in the event that the Optionee becomes employed on less than a full-time
   basis (such new percentage shall be determined by the Company at the time the
   Optionee becomes employed on less than a full time basis and shall be set
   forth in a replacement option agreement to be executed at that time), this
   Option shall be vested and exercisable with respect to the percentage of the
   total number of Option Shares as listed on the vesting and exercise schedule
   attached to this certificate.
4. Exercise of Option.
   ---------------------
   (a) Optionee may exercise only vested portions of this Option and only in the
       following manner. From time to time prior to the earlier to occur of (i)
       the termination hereof in accordance with the provisions of this Option,
       or (ii) the Expiration Date (as set forth in Paragraph 5 herein) with
       respect to a given portion of this Option, the Optionee may give written
       notice to the Company of his or her election to purchase some or all of
       the Option Shares for which this Option may be exercised at the time of
       such notice. Said notice shall specify the number of Option Shares to be
       purchased and shall be accompanied (i) by payment therefor in cash and
       (ii) by such agreement, statement or other evidence as the Company may
       require in order to satisfy itself that the issuance of the Option Shares
       being purchased pursuant to such exercise and any subsequent resale
       thereof will be in compliance with applicable laws and regulations,
       including without limitation all applicable federal and state securities
       laws and regulations. This Option shall not be exercisable for any
       fractional share.
<PAGE>
 
  a    Certificates for the Option Shares so purchased will be issued to the
       Optionee upon compliance to the satisfaction of the Company with all
       requirements under applicable laws or regulations in connection with such
       issuance, including without limitation, if said Option Shares have not
       been registered under the Securities Act of 1933, as amended (the "Act"),
       receipt of a representation from the Optionee upon each exercise of this
       Option that the Optionee is purchasing the Option Shares for his or her
       own account and not with a view to any resale or distribution thereof,
       the legending of any certificate representing said Option Shares, and the
       imposition of a stop transfer order with respect thereto, to prevent a
       resale or distribution in violation of federal or state securities laws.
       Until the Optionee shall have complied with the requirements hereof and
       of the Plan, the Company shall be under no obligation to issue the Option
       Shares subject to this Option, and the determination of the MRC (as
       defined in the Plan) as to such compliance shall be final and binding on
       the Optionee. The Optionee shall not be deemed for any purpose to be the
       owner of any Option Shares subject to this Option until such Option
       Shares shall have been issued in accordance with the foregoing
       provisions.

  b    Notwithstanding any other provision hereof or of the Plan, no portion of
       this Option shall be exercisable (i) after its termination in accordance
       with the provisions hereof, (ii) after the Expiration Date applicable
       thereto (as set forth in Paragraph 5 herein), or (iii) at any time unless
       all necessary regulatory or other approvals have been received.

  c    To the extent that this Option is not exercised in full, it will be
       deemed to have been exercised first for any remaining Option Shares in
       the Installment (as defined in Paragraph 5 herein) which would otherwise
       expire on the next succeeding Expiration Date, then for any remaining
       Option Shares in the Installment which would otherwise expire on the
       second succeeding Expiration Date and so on, thereby reducing the number
       of Option Shares with respect to which this Option will expire on such
       Expiration Dates.

5.   Expiration Date of Option and Underlying Option Shares. This Option will
     ------------------------------------------------------                  
     expire and terminate in equal Installments (each, an "Installment") on the
     following dates (each, an "Expiration Date"): (a) the date which is the
     fifth anniversary of the Vesting Start Date with respect to the portion of
     this Option which vests one year after the Vesting Start Date; (b) the date
     which is the sixth anniversary of the Vesting Start Date with respect to
     the portion of this Option which vests during the period beginning 13
     months after the Vesting Start Date and ending 24 months after the Vesting
     Start Date; (c) the date which is the seventh anniversary of the Vesting
     Start Date with respect to the portion of this Option which vests during
     the period beginning 25 months after the Vesting Start Date and ending 36
     months after the Vesting Start Date; and (d) the date which is the eighth
     anniversary of the Vesting Start Date with respect to the portion of this
     Option which vests during the period beginning 37 months after the Vesting
     Start Date and ending 48 months after the Vesting Start Date.

6.   Termination of Employment.  This Option, as to any unexercised portion
     --------------------------                                            
     hereof, shall terminate on the date three (3) months after the date on
     which the Optionee is no longer employed by the Company or a subsidiary as
     defined in the Code (and, except as set forth in clauses (a) and (b) below,
     this Option shall not vest with respect to any additional Option Shares
     following the date on which the Optionee is no longer employed by the
     Company or a subsidiary as defined in the Code); provided, however, that
     (a) if such termination of employment results from the Optionee's permanent
     and total disability as defined in Section 22(e)(3) of the Code, this
     Option may be exercised, whether or not exercisable at the time of 
<PAGE>
 
     such termination, until the date twelve (12) months after such termination,
     or until the applicable Expiration Date with respect to any particular
     portion of this Option (as set forth in Paragraph 5 herein), whichever
     first occurs, and (b) if such termination of employment results from the
     Optionee's death, this Option may be exercised, whether or not exercisable
     at the time of such termination, by the Optionee's executors or
     administrators within twenty-four (24) months thereafter, or until the
     applicable Expiration Date with respect to any particular portion of this
     Option (as set forth in Paragraph 5 herein), whichever first occurs. No
     Option will confer upon the Optionee any right to continued employment by
     the Company or any subsidiary of the Company, nor will it interfere in any
     way with the Optionee's right or the Company's or any such subsidiary's
     right to terminate, or otherwise modify the terms of, the Optionee's
     employment at any time.

7.   Transferability.  Except as otherwise permitted by the Plan, each of this
     ----------------                                                         
     certificate and this Option is personal to the Optionee, is non-
     assignable and is not transferable in any manner, by operation of law or
     otherwise, other than by will or by the laws of descent and distribution,
     and is exercisable, during the Optionee's lifetime, only by the Optionee.

8.   Effect of Certain Transactions. If (i) the Company is to be merged into
     -------------------------------                                        
     another entity, or if one or more entities is to be merged into the Company
     or if there is to be a consolidation of the Company and one or more
     entities and, in any such case, the shares of Common Stock are to be
     converted into cash, securities or other property other than shares of
     Common Stock (an "Acquisition"), or (ii) if the Company is to be
     liquidated, or is to sell or otherwise dispose of substantially all of its
     assets to another entity while unexercised Options remain outstanding under
     the Plan (a "Sale"), then: (a) the time for exercise of any unexercised and
     unexpired portion of this Option, including the then unvested portion of
     this Option, shall be accelerated to immediately prior to the consummation
     of such Acquisition or Sale, and (b) this Option shall terminate
     immediately after the effective date of such Acquisition or Sale; provided,
     however, that the foregoing clauses (a) and (b) shall not apply to any
     transaction in which the former stockholders of the Company immediately
     after such transaction hold or receive by reason of their prior ownership
     of shares of capital stock of the Company shares of capital stock of the
     resulting or surviving corporation constituting a majority of the voting
     power of all outstanding stock of such resulting or successor corporation.

9.   Tax Withholding.  The Optionee shall, not later than the date as of which
     ----------------                                                         
     the exercise of this Option or disposition of Option Shares becomes a
     taxable event for Federal income tax purposes, pay to the Company or make
     arrangements satisfactory to the MRC for payment of any Federal, state, and
     local taxes required by law to be withheld.

10.  Notice to Company of Disqualifying Disposition. If this Option is intended
     ------------------------------------------------                          
     to be an incentive stock option under the Plan set forth on the face of
     this certificate, by acceptance hereof, the Optionee agrees to notify the
     Company in writing immediately after he or she makes a Disqualifying
     Disposition (as described in Sections 421, 422 and 424 of the Code and
     regulations thereunder) of any stock acquired pursuant to the exercise of
     incentive stock options under the Plan. A Disqualifying Disposition is
     generally any disposition occurring within two years of the date the
     incentive stock option was granted or within one year of the date the
     incentive stock option was exercised, whichever period ends later. Such
     notice shall be mailed or delivered to the Company at its principal place
     of business.

11. Representations.  By acceptance of this Option, the Optionee agrees,
    ----------------                                                    
 acknowledges and understands that a purchase of shares under this Option will
 not be made with a view to their distribution, as that term is used in the Act
 unless, in the opinion of counsel to the Company such distribution is in
 compliance with or exempt from the registration and prospectus requirements of
 the Act, and the Optionee agrees to sign a certificate to such effect at the
 time of exercising this option and agrees that the certificate for the shares
 so purchased may be inscribed with a legend to ensure compliance with the Act.
