     Re:  Amendment of SilverStream Options
          ---------------------------------

Dear [Name2]:

We would like to modify all of the options granted to you by SilverStream on or
prior to today's date (the "Prior Options") to provide that upon a change of
control of SilverStream, one-half of your unvested options will automatically
vest and the balance of your unvested options will vest over a period of time
that is one-half of the vesting period then remaining. Accordingly, subject to
your agreement hereof, all of your Prior Options are hereby amended by adding
the following language to each Prior Option agreement:

     Inthe event of (a) a merger or consolidation of the Company with or into
     another entity, (b) the sale of all or substantially all of the assets of
     the Company, or (c) the acquisition by another entity of at least fifty
     percent (50%) of the Company's then-outstanding voting stock (each an
     "Acquisition Event"), then (x) fifty percent (50%) of the then-unvested
     Shares granted hereunder shall automatically vest and become immediately
     exercisable as of a date (the "Accelerated Vesting Date") prior to the
     effective date of the Acquisition Event as specified by the Board of
     Directors of the Company prior to such effective date and (y) the balance
     of any then-unvested Shares granted hereunder (after giving effect to
     subsection (x) of this paragraph) shall vest, pro rata, over a period of
     time that is 50% of the vesting period then remaining before giving effect
     to the Acquisition Event. At least 10 business days prior to the effective
     date of the Acquisition Event (but in any event not later than the
     Accelerated Vesting Date), the Company shall give the Participant notice of
     such Acquisition Event and advise the Participant of his or her right to
     exercise the Shares accelerated by the occurrence of such Acquisition
     Event.

Except for the foregoing amendment, all other terms of your Prior Options are
unaffected hereby.

Please indicate your agreement with the above amendment by signing a copy of
this letter where indicated below and returning the signed copy to me at your
earliest convenience.

Please contact me if you have any questions.

                           SILVERSTREAM SOFTWARE, INC.

               THE AMENDED AND RESTATED 1997 STOCK INCENTIVE PLAN
               --------------------------------------------------

     This Certificate evidences the grant by SilverStream Software, Inc., a
Delaware corporation (the "Company"), to the person named below (the
"Participant"), of an option to purchase, in whole or in part, shares of common
stock (the "Shares"), $.001 par value per share, of the Company ("Common Stock")
exercisable on the following terms and conditions and those set forth on the
reverse of this Certificate and in the Company's Amended and Restated 1997 Stock
Incentive Plan (the "Plan"). It is intended that the option evidenced by this
Certificate shall not be an incentive stock option as defined in Section 422 of
the Internal Revenue Code of 1986, as amended, and any regulations promulgated
thereunder (the "Code"). Except as otherwise indicated by the context, the term
"Participant," as used in this option, shall be deemed to include any person who
acquires the right to exercise this option validly under its terms.

     Name of Participant:                        Steve Benfield
     Number of Shares:                                   10,000

     The option will become exercisable ("vest") as to 25% of the original
number of Shares on the date that is 180 days after the Grant Date (the "First
Vesting Date") and as to an additional 6.25% of the original number of Shares at
the end of each successive full three-month period following the First Vesting
Date until fully vested. This option shall expire upon, and will not be
exercisable after, the Final Exercise Date. The right of exercise shall be
cumulative so that to the extent the option is not exercised in any period to
the maximum extent permissible it shall continue to be exercisable, in whole or
in part, with respect to all shares for which it is vested until the earlier of
the Final Exercise Date or the termination of this option pursuant to its terms.

     The immediately preceding paragraph to the contrary notwithstanding, in the
event of (a) a merger or consolidation of the Company with or into another
entity, (b) the sale of all or substantially all of the assets of the Company,
or (c) the acquisition by another entity of at least fifty percent (50%) of the
Company's then-outstanding voting stock (each an "Acquisition Event"), then (x)
fifty percent (50%) of the then-unvested Shares granted hereunder shall
automatically vest and become immediately exercisable as of a date (the
"Accelerated Vesting Date") prior to the effective date of the Acquisition Event
as specified by the Board of Directors of the Company prior to such effective
date and (y) the balance of any then-unvested Shares granted hereunder (after
giving effect to subsection (x) of this paragraph) shall vest, pro rata, over a
period of time that is 50% of the vesting period then remaining before giving
effect to the Acquisition Event. At least 10 business days prior to the
effective date of the Acquisition Event (but in any event not later than the
Accelerated Vesting Date), the Company shall give the Participant notice of such
Acquisition Event and advise the Participant of his or her right to exercise the
Shares accelerated by the occurrence of such Acquisition Event.

     By acceptance of this option, the Participant agrees to the terms and
conditions hereof and acknowledges receipt of a copy of the Amended and Restated
1997 Stock Incentive Plan.

                  furniture currently located therein for up to sixty (60) days
                  commencing on the date specified in such notice to Landlord.
                  With MIT's prior written consent, which consent shall not be
                  unreasonably withheld, conditioned or delayed, Akamai may use
                  the Transition Space for more than sixty (60) days in
                  connection with Akamai's move out of the Building 500
                  Premises. Notwithstanding anything to the contrary set forth
                  herein, in no event shall Akamai have the right to use the
                  Transition Space after November 30, 2002. Akamai's right to
                  use the Transition Space is not to be construed as in any way
                  granting to Akamai any interest in the Transition Space. Upon
                  Akamai's written request at any time after April 1, 2002, MIT
                  will inform Akamai whether the Transition Space will be
                  available for Akamai's use pursuant to the terms of this
                  Section 9.

         10.      Notices. Any notice, request or demand ("NOTICE") permitted or
                  required to be given by the terms and provisions of this
                  Agreement, or by any law or governmental regulation, either by
                  MIT or Akamai, shall be in writing and delivered by hand (with
                  evidence of receipt) or by nationally recognized overnight
                  courier (with evidence of receipt), addressed to the other
                  party at the address of the other party first set forth above.
                  A copy of all Notices sent to MIT shall be sent Daniel D.
                  Sullivan, Esquire, Brown Rudnick Berlack Israels LLP, One
                  Financial Center, Boston, MA 02111. Either party hereto may
                  designate a different address for Notices to such party by
                  serving Notice of such change in accordance with this section.

         11.      Miscellaneous. This Agreement shall be deemed to have been
                  executed and delivered within the Commonwealth of
                  Massachusetts, and the rights and obligations of MIT and
                  Akamai hereunder shall be construed and enforced in accordance
                  with, and governed by, the laws of the Commonwealth of
                  Massachusetts without regard to the laws governing conflicts
                  of laws. If any term of this Agreement or the application
                  thereof to any person or circumstances shall be invalid and
                  unenforceable, the remaining provisions of this Agreement, the
                  application or such term to persons or circumstances other
                  than those as to which it is invalid or unenforceable, shall
                  not be affected. This Agreement is binding upon and shall
                  inure to the benefit of MIT and Akamai, their respective
                  agents, employees, representatives, officers, directors,
                  divisions, subsidiaries, affiliates, assigns, heirs,
                  successors-in-interest and shareholders. Each party has
                  cooperated in the drafting and preparation of this Agreement
                  and, therefore, in any construction to be made of this
                  Agreement, the same shall not be construed against either
                  party. Any litigation relating to this Agreement shall be
                  brought in the state or federal courts in the Commonwealth of
                  Massachusetts and each party consents to personal jurisdiction
                  in such courts. In the event of litigation relating to this
                  Agreement, the prevailing party shall be entitled to
                  reimbursement from the other party of its reasonable
                  attorneys' fees and costs. This Agreement constitutes the
                  entire agreement of the parties with respect to the subject
                  matter hereof and supersedes all prior and contemporaneous
                  oral and written agreements and discussions, and may not be
                  amended, waived, discharged or terminated except by a written
                  instrument signed by all the parties hereto. This Agreement
                  may be executed in as many counterparts as may be required,
                  and it shall not be necessary that the signature of each
                  party, or that the signatures of all persons required to bind
                  any party, appear on each counterpart. It shall be sufficient
                  that the signature of each party, or that the signatures of
                  the persons required to bind any party, appear on one or more
                  of such counterparts. All counterparts shall collectively
                  constitute a single agreement.
