BBN INTERNET SERVICES CORPORATION

                                  EXHIBIT 10.3
                            1994 STOCK OPTION PLAN

     1.    PURPOSE
           _______

          The purpose of this 1994 Stock Option Plan (the "Plan") is to
     advance the interests of BBN Internet Services Corporation (the
     "Company") by enhancing the ability of the Company and its parent and
     subsidiaries to attract and retain able employees, consultants or
     advisors to the Company; to reward such individuals for their
     contributions; and to encourage such individuals to take into account
     the long-term interests of the Company through interests in shares of
     the Company's common stock, $.01 par value (the "Stock").  Any
     employee, consultant, or advisor selected to receive an award under
     the Plan is referred to as a "participant".

          Options granted pursuant to the Plan may be incentive stock
     options as defined in section 422 of the Internal Revenue Code of 1986
     (as from time to time amended, the "Code") (any option that is
     intended so to qualify as an incentive stock option being referred to
     herein as an "incentive option"), or options that are not incentive
     options, or both.  Except as otherwise expressly provided with respect
     to an option grant, no option granted pursuant to the Plan shall be an
     incentive option.

     2.    ADMINISTRATION
           ______________

          The Plan shall be administered by the Board of Directors (the
     "Board") of the Company.  The Board shall have authority, not
     inconsistent with the express provisions of the Plan: (a) to grant
     awards consisting of options or stock appreciation rights ("SARs"), or
     both, to such participants as the Board may select; (b) to determine
     the time or times when awards shall be granted and the number of
     shares of Stock subject to each award; (c) to determine which options
     are, and which options are not, intended to be incentive options; (d)
     to determine the terms and conditions of each award; (e) to prescribe
     the form or forms of any instruments evidencing awards and any other
     instruments required under the Plan and to change such forms from time
     to time; (f) to adopt, amend, and rescind rules and regulations for
     the administration of the Plan; and (g) to interpret the Plan and to
     decide any questions and settle all controversies and disputes that
     may arise in connection with the Plan.  Such determinations of the
     Board shall be conclusive and shall bind all parties.  Subject to
     Section 8, the Board shall also have the authority, both generally and
     in particular instances, to waive compliance by a participant with any
     obligation to be performed by the participant under an award, to waive
     any condition or provision of an award, and to amend or cancel any
     award (and if an award is cancelled, to grant a new award on such
     terms as the Board shall specify) except that the Board may not take
     any action with respect to an outstanding award that would adversely
     affect the rights of the participant under such award without such
     participant's consent.  Nothing in the preceding sentence shall be
     construed as limiting the power of the Board to make adjustments
     required by Section 4(c) and Section 6(j).

          The Board may, in its discretion, delegate some or all of its
     powers with respect to the Plan to a committee (the "Committee"), in
     which event all references (as appropriate) to the Board hereunder

     shall be deemed to refer to the Committee.  The Committee, if one is
     appointed, shall consist of at least two directors.  A majority of the
     members of the Committee shall constitute a quorum, and all
     determinations of the Committee shall be made by a majority of its
     members.  Any determination of the Committee under the Plan may be
     made without notice or meeting of the Committee by a writing signed by
     a majority of the Committee members.  On and after registration of the
     Stock under the Securities Exchange Act of 1934 (the "1934 Act"), the
     Board shall delegate the power to select directors and officers to
     receive awards under the Plan and the timing, pricing, and amount of
     such awards to a Committee, all members of which shall be
     disinterested persons within the meaning of Rule 16b-3 under the 1934
     Act and "outside directors" within the meaning of section
     162(m)(4)(c)(i) of the Code.



     3.    EFFECTIVE DATE AND TERM OF PLAN
           _______________________________

          The Plan shall become effective on the date on which it is
     approved by the shareholders of the Company.  Grants of awards under
     the Plan may be made prior to that date (but after Board adoption of
     the Plan), subject to approval of the Plan by the shareholders.

          No awards shall be granted under the Plan after the completion of
     ten years from the date on which the Plan was adopted by the Board,
     but awards previously granted may extend beyond that date.

     4.   SHARES SUBJECT TO THE PLAN
          __________________________

          (a)   NUMBER OF SHARES.  Subject to adjustment as provided in
     Section 4(c), the aggregate number of shares of Stock that may be
     delivered upon the exercise of award granted under the Plan shall be
     1,200,000.  If any award granted under the Plan terminates without
     having been exercised in full, or upon exercise is satisfied other
     than by delivery of Stock, the number of shares of Stock as to which
     such award was not exercised shall be available for future grants
     within the limits set forth in this Section 4(a).

          (b)   SHARES TO BE DELIVERED.  Shares delivered under the Plan
     shall be authorized but unissued Stock or, if the Board so decides in
     its sole discretion, previously issued Stock acquired by the Company
     and held in its treasury.  No fractional shares of Stock shall be
     delivered under the Plan.

          (c)   CHANGES IN STOCK.  In the event of a stock dividend, stock
     split, or combination of shares, recapitalization, or other change in
     the Company's capital stock, the number and kind of shares of stock or
     securities of the Company subject to awards then outstanding or
     subsequently granted under the Plan, the exercise price of such
     awards, the maximum number of shares or securities that may be
     delivered under the Plan, and other relevant provisions shall be
     appropriately adjusted by the Board, whose determination shall be
     binding on all persons.

          The Board may also adjust the number of shares subject to
     outstanding awards, the exercise price of outstanding awards, and the
     terms of outstanding awards, to take into consideration material
     changes in accounting practices or principles, extraordinary
     dividends, consolidations or mergers (except as described in Section
     6(j)), acquisitions or dispositions of stock or property, or any other

     event if it is determined by the Board that such adjustment is
     appropriate to avoid distortion in the operation of the Plan, provided
     that no such adjustment shall be made in the case of an incentive
     option, without the consent of the participant, if it would constitute
     a modification, extension, or renewal of the option within the meaning
     of section 424(h) of the Code.

     5.    ELIGIBILITY FOR AWARDS
           ______________________

          Persons eligible to receive awards under the Plan shall be those
     employees of the Company, its parent, or subsidiaries, or consultants,
     or advisors to any of them, who in the opinion of the Board are in a
     position to make a contribution to the Company.  Participants shall be
     selected by the Board.  A parent for purposes of the Plan shall be a
     corporation which owns, directly or indirectly, 50% or more of the
     total combined voting power of all classes of the Company's stock.  A
     subsidiary for purposes of the Plan shall be (i) a corporation in
     which the Company owns, directly or indirectly, stock possessing 50%
     or more of the total combined voting power of all classes of stock, or
     (ii) a corporation in which the Company's parent owns, directly or
     indirectly, stock possessing 50% or more of the total combined voting
     power of all classes of stock.  The Board may grant awards covering up
     to the entire number of shares available for issuance under the Plan
     (as determined under Section 4(a)) to any one participant or to
     several participants, in the sole discretion of the Board.

          Incentive options shall be granted only to "employees" as defined
     in the provisions of the Code or regulations thereunder applicable to
     incentive stock options.

     6.    TERMS AND CONDITIONS OF OPTIONS AND SARs
           ________________________________________

          (a)   EXERCISE PRICE OF OPTIONS.  The exercise price of each
     option shall be determined by the Board but in the case of an
     incentive option shall not be less than 100% (110%, in the case of an
     incentive option granted to a ten-percent shareholder) of the fair
     market value of the Stock at the time the option is granted; nor shall
     the exercise price be less, in the case of an original issue of
     authorized stock, than par value.  For this purpose, "fair market
     value" in the case of incentive options shall have the same meaning as
     it does in the provisions of the Code and the regulations thereunder
     applicable to incentive options; and "ten-percent shareholder" shall
     mean any participant who at the time of grant owns directly, or by
     reason of the attribution rules set forth in section 424(d) of the
     Code is deemed to own, stock possessing more than 10% of the total
     combined voting power of all classes of stock of the Company or of any
     of its parent or subsidiary corporations.

          (b)   DURATION OF OPTIONS.  An option shall be exercisable during
     such period or periods as the Board may specify.  The latest date on
     which an option may be exercised (the "Final Exercise Date") shall be
     the date which is ten years (five years, in the case of an incentive
     option granted to a "ten-percent shareholder" as defined in (a) above)
     from the date the option was granted or such earlier date as may be
     specified by the Board at the time the option is granted.

          (c)   EXERCISE OF OPTIONS.

     (1)   An option shall become exercisable at such time or times and
     upon such conditions as the Board shall specify.  In the case of an
     option not immediately exercisable in full, the Board may at any time

     accelerate the time at which all or any part of the option may be
     exercised.

     (2)   Any exercise of an option shall be in writing, signed by the
     proper person and furnished to the Company, accompanied by (i) such
     documents, representations, agreements, and certifications as may be
     required by the Board and (ii) payment in full as specified below in
     Section 6(d) for the number of shares for which the option is
     exercised.

     (3)   In the case of an option that is not an incentive option, the
     Board shall have the right to require that the participant exercising
     the option remit to the Company an amount sufficient to satisfy any
     federal, state, or local withholding tax requirements (or make other
     arrangements satisfactory to the Company with regard to such taxes)
     prior to the delivery of any Stock pursuant to the exercise of the
     option.  If permitted by the Board either at the time of the grant of
     the option or the time of exercise, the participant may elect, at such
     time and in such manner as the Board may prescribe, to satisfy such
     withholding obligation by (i) delivering to the Company Stock owned by
     such individual having a fair market value equal to such withholding
     obligation, or (ii) requesting that the Company withhold from the
     shares of Stock to be delivered upon the exercise a number of shares
     of Stock having a fair market value equal to such withholding
     obligation.

           In the case of an incentive option, the Board may require as a
     condition of exercise that the participant exercising the option agree
     to inform the Company promptly of any disposition (within the meaning
     of section 424(c) of the Code and the regulations thereunder) of Stock
     received upon exercise.  In addition, if at the time the option is
     exercised the Board determines that under applicable law and
     regulations the Company could be liable for the withholding of any
     federal or state tax with respect to a disposition of the Stock
     received upon exercise, the Board may require as a condition of
     exercise that the participant exercising the option agree to give such
     security as the Board deems adequate to meet the potential liability
     of the Company for the withholding of tax, and to augment such
     security from time to time in any amount reasonably deemed necessary
     by the Board to preserve the adequacy of such security.

     (4)   If an option is exercised by the executor or administrator of a
     deceased participant, or by the person or persons to whom the option
     has been transferred by the participant's will or the applicable laws
     of descent and distribution, the Company shall be under no obligation
     to deliver Stock pursuant to such exercise until the Company is
     satisfied as to the authority of the person or persons exercising the
     option.

          (d)   PAYMENT FOR STOCK.  Stock purchased upon exercise of an
     option under the Plan shall be paid for as follows:  (i) in cash,
     check acceptable to the Company (determined in accordance with such
     guidelines as the Board may prescribe), or money order payable to the
     order of the Company, or (ii) if so permitted by the Board (which, in
     the case of an incentive option, shall specify such method of payment
     at the time of grant), (A) through the delivery of shares of Stock
     (which, in the case of Stock acquired from the Company, shall have
     been held for at least six months unless the Board specifies a shorter
     period) having a fair market value on the date of exercise equal to
     the purchase price, or (B) by delivery of a promissory note of the
     participant to the Company, such note to be payable on such terms as
     are specified by the Board, or (C) by delivery of an unconditional and
     irrevocable undertaking by a broker to deliver promptly to the Company

     sufficient funds to pay the exercise price, or (D) by any combination
     of the permissible forms of payment; provided, that if the Stock
     delivered upon exercise of the option is an original issue of
     authorized Stock, at least so much of the exercise price as represents
     the par value of such Stock shall be paid other than with a personal
     check or promissory note of the person exercising the option.

          (e)   STOCK APPRECIATION RIGHTS.  The Board in its discretion may
     grant SARs either in tandem with or independent of options awarded
     under the Plan.  Except as hereinafter provided, each SAR will entitle
     the participant to receive upon exercise, with respect to each share
     of Stock to which the SAR relates, the excess of (i) the share's value
     on the date of exercise, over (ii) the share's fair market value on
     the date it was granted.  For purposes of clause (i), "value" shall
     mean fair market value; provided, that the Board may adjust such value
     to take into account dividends on the Stock and may also grant SARs
     that provide, in such limited circumstances following a change in
     control of the Company (as determined by the Board) as the Board may
     specify, that "value" for purposes of clause (i) is to be determined
     by reference to an average value for the Stock during a period
     immediately preceding the change in control, all as determined by the
     Board.  The amount payable to a participant upon exercise of an SAR
     shall be paid either in cash or in shares of Stock, as the Board
     determines.  Each SAR shall be exercisable during such period or
     periods and on such terms as the Board may specify.  No SAR shall be
     exercisable after the date which is ten years from the date of grant.

          (f)   DELIVERY OF STOCK.  A participant shall not have the rights
     of a shareholder with regard to awards under the Plan except as to
     Stock actually received by such participant under the Plan.

          The Company shall not be obligated to deliver any shares of Stock
     (i) until, in the opinion of the Company's counsel, all applicable
     federal and state laws and regulations have been complied with, (ii)
     if the outstanding Stock is at the time listed on any stock exchange,
     until the shares to be delivered have been listed or authorized to be
     listed on such exchange upon official notice of issuance, and (iii)
     until all other legal matters in connection with the issuance and
     delivery of such shares have been approved by the Company's counsel.
     If the sale of Stock has not been registered under the Securities Act
     of 1933, as amended, the Company may require, as a condition to
     exercise of the award, such representations or agreements as counsel
     for the Company may consider appropriate to avoid violation of such
     Act and may require that the certificates evidencing such Stock bear
     an appropriate legend restricting transfer.

          (g)   NONTRANSFERABILITY OF AWARDS.  No award may be transferred
     other than by will or by the laws of descent and distribution, and
     during a participant's lifetime an award may be exercised only by him
     or her.

          (h)   DEATH.  Except as otherwise provided in an award, if a
     participant dies, each award held by the participant immediately prior
     to death may be exercised, to the extent it was exercisable
     immediately prior to death, by his executor or administrator, or by
     the person or persons to whom the award is transferred by will or the
     applicable laws of descent and distribution, at any time within the
     period ending (i) 180 days after the participant's death (in the event
     the participant's employment or other service relationship with the
     Company shall terminate by reason of death), or (ii) 120 days after
     the participant's death (in the event the participant dies within the
     60-day period following termination of the participant's employment or
     other service relationship with the Company), or such longer period as

     the Committee may determine.  In no event shall an award be exercised
     beyond the Final Exercise Date.  Except as otherwise provided in an
     award, all awards held by a participant immediately prior to death
     that are not then exercisable shall terminate on the date of death.

          (i)   OTHER TERMINATION OF SERVICE.  Except as otherwise provided
     in an award, if a participant's employment or other service
     relationship with the Company terminates for any reason other than
     death, all awards held by the participant shall terminate to the
     extent not exercisable immediately prior to such event.  To the extent
     exercisable immediately prior to termination of employment or other
     service relationship, the award shall continue to be exercisable
     thereafter for a period of 60 days (or such longer period as the Board
     may determine, but in no event beyond the Final Exercise Date), unless
     the participant's employment or other service relationship is
     terminated for "cause" as a result of the participant's misconduct
     which, in the judgment of the Board, casts discredit on him or her, or
     is otherwise harmful to the business, interests, or reputation of the
     Company, its parent, or a subsidiary, in which case all awards shall
     terminate immediately.  The Board may in any award provide for post-
     termination exercise provisions different from those expressly set
     forth in the preceding two sentences or in (h) above, including
     without limitation terms allowing a later exercise by a former
     employee, consultant, or advisor (or, in the case of a former
     employee, consultant, or advisor who is deceased, the person or
     persons to whom the award is transferred by will or the laws of
     descent and distribution) as to all or any portion of the award not
     exercisable immediately prior to termination or employment or other
     service relationship, but in no case may an award be exercised after
     the Final Exercise Date.  Except as otherwise provided in an award,
     after completion of that 60-day or longer period, such awards shall
     terminate to the extent not previously exercised, expired, or
     terminated.  For purposes of this Plan, the service relationship shall
     not be considered terminated (i) in the case of sick leave or other
     bona fide leave of absence approved for purposes of the Plan by the
     Board, so long as the participant's right to reemployment or continued
     service is guaranteed either by statute or by contract, or (ii) in the
     case of a transfer of employment or service relationship between the
     Company and a subsidiary or parent, or between subsidiaries of the
     Company or parent (provided the participant's direct or indirect
     service to the Company continues), or to the service of a corporation
     (or a parent or subsidiary corporation of such corporation) issuing or
     assuming an award in a transaction to which section 424(a) of the Code
     applies.

          (j)   MERGERS, ETC.  In the event of any merger, consolidation,
     dissolution, or liquidation of the Company, the Board in its sole
     discretion may, as to any outstanding awards, make such substitution
     or adjustment in the aggregate number of shares reserved for issuance
     under the Plan and in the number and purchase price (if any) of shares
     subject to such awards as it may determine, or accelerate, amend, or
     terminate such awards upon such terms and conditions as it shall
     provide (which, in the case of the termination of the vested portion
     of any award, shall require payment or other consideration which the
     Board deems equitable in the circumstances).

          The Board may grant awards under the Plan in substitution for
     awards held by employees, consultants, or advisors of another
     corporation who concurrently become employees, consultants, or
     advisors of the Company, its parent, or a subsidiary as the result of
     a merger or consolidation of that corporation with the Company, its
     parent, or a subsidiary, or as the result of the acquisition by the
     Company, its parent, or a subsidiary of property or stock of that

     corporation.  The Company may direct that substitute awards be granted
     on such terms and conditions as the Board considers appropriate in the
     circumstances.

          (k)   CANCELLATION OF AWARDS.  The Board may provide in any award
     that the award shall be cancelled or rescinded and any associated
     shares forfeited, and the participant shall be obligated to pay to the
     Company any gain received upon exercise, in the event that the
     participant competes with the Company, discloses confidential
     information of the Company, or otherwise is not in compliance with
     applicable provisions of any award, in each case on such terms and
     conditions as the Board considers appropriate in the circumstances.

     7.     EMPLOYMENT RIGHTS
            _________________

          Neither the adoption of the Plan nor the grant of awards shall
     confer upon any participant any right to continue as an employee of,
     or consultant or advisor to, the Company, its parent, or any
     subsidiary of either or affect in any way the right of the Company,
     its parent, or a subsidiary of either to terminate the participant's
     relationship at any time.  Except as specifically provided by the
     Board in any particular case, the loss of existing or potential profit
     in awards granted under this Plan shall not constitute an element of
     damages in the event of termination of the relationship of a
     participant even if the termination is in violation of an obligation
     of the Company, its parent, or a subsidiary of either to the
     participant by contract or otherwise.


     8.     EFFECT, DISCONTINUANCE, CANCELLATION, AMENDMENT, AND TERMINATION
            ________________________________________________________________

          Neither adoption of the Plan nor the grant of awards to a
     participant shall affect the Company's right to make awards to such
     participant that are not subject to the Plan, to issue to such
     participant Stock as a bonus or otherwise, or to adopt other plans or
     arrangements under which Stock may be issued, and shall in no way
     affect the Company's right to operate its business at its sole
     discretion.

          The exercise of certain awards granted under the Plan may be made
     contingent upon the closing of an initial public offering of the
     Company's Stock.  The grant of such awards under the Plan shall in no
     way obligate the Company to consummate or consider a public offering
     of Stock, and the failure of the Company to close a public offering of
     Stock shall not entitle a participant granted such an award to any
     substitute award or other benefit, or to any damages.

          The Board may at any time discontinue granting awards under the
     Plan.  With the consent of the participant, the Board may at any time
     cancel an existing award in whole or in part and grant another award
     for such number of shares as the Board specifies.  The Board may at
     any time or times amend the Plan or any outstanding award for the
     purpose of satisfying the requirements of section 422 of the Code or
     of any changes in applicable laws or regulations or for any other
     purpose that may at the time be permitted by law, or may at any time
     terminate the Plan as to any further grants of awards; except that no
     such amendment shall adversely affect the rights of any participant
     (without his or her consent) under any award previously granted.
