			      STRATUS COMPUTER, INC.
		       STOCK OPTION PLAN (January, 1983)
			    RESTATEMENT NUMBER FIVE                                          

1.    Purpose.   The purpose of this Plan is to advance the interests of
      Stratus Computer, Inc. (the "Company") by providing an opportunity to
      selected key employees of the Company and its subsidiaries to purchase
      stock of the Company through the exercise of options granted under this
      Plan.   By encouraging such stock ownership, the Company seeks to
      attract, retain and motivate employees of training, experience and
      ability.  It is intended that this purpose will be effected by the
      granting of stock options as provided herein.


2.          Amendment and Restatement of Prior Plan.   This plan continues, in
	    amended and restated form, the Incentive Stock Option Plan
	    (January, 1983) (the "Incentive Stock Option Plan"), as previously
	    amended and restated effective October 28, 1986 ("Restatement
	    Number One"), February 7, 1989 ("Restatement Number Two"), October
	    16, 1990 ("Restatement Number Three") and January 28, 1992
	    ( Restatement Number Four ) which Amendment extended the
	    termination date of the Plan until December 31, 2003 and for
	    purposes of Section 422(b)2 of the Internal Revenue Code of 1986,
	    as Amended (the  Code ), constitutes a new plan.   This Stratus
	    Computer, Inc. Stock Option Plan (January, 1983) Restatement
	    Number Five (the "Plan"), effective as of August 1, 1995, reflects
	    further amendments to the Plan adopted by the Board of Directors
	    of the Company (the "Board") on August 1, 1995, the sole purpose
	    of which is to cause the Plan to comply with the requirements of
	    Rule 16b-3 promulgated under Section 16 of the Securities Exchange
	    Act of 1934, as Amended ( Rule 16b-3 ).

3.          Effective Date.  The Plan became effective as of January 1, 1983. 
	    This Restatement Number Five of the Plan became effective on
	    August 1, 1995, the date the last amendment incorporated in this
	    restatement was adopted by the Board.  To the extent at any time
	    that amendments are made to the Plan for which shareholder
	    approval is necessary under applicable tax or securities laws or
	    under the Board action adopting such amendment, options that may
	    be granted only as a  result of such amendments may be granted
	    before such approval, but no such options may be exercised until
	    such approval is obtained and such options will be null and void
	    if such approval is not obtained.

4.          Stock Subject to the Plan.   The shares that may be granted under
	    this Plan shall not exceed in the aggregate 9,380,200 shares of
	    the $.01 par value Common Stock of the Company (the  "Shares"); 
	    provided, however, that such maximum number of Shares shall be
	    reduced by the number of any  Shares that are made subject to
	    options (which have not subsequently expired or been terminated
	    before exercise) pursuant to the Stratus Computer, Inc.  Non-
	    Qualified  Common Stock  Option  Plan.   Any Shares subject to an
	    option under this Plan which for any reason expires or is
	    terminated unexercised as to such Shares may again be the  subject
	    of an option under the Plan.  In addition, any Shares purchased by
	    an optionee upon exercise of an option under this Plan that are
	    subsequently repurchased by the Company pursuant to the terms of
	    such option may again be the  subject of an option under the Plan. 
	     The Shares delivered upon exercise of options under this Plan
	    may, in whole or in part, be either authorized but unissued Shares
	    or issued Shares reacquired by the Company.


5.          Administration.   This Plan shall be administered by a committee
	    (the "Stock Option Committee") consisting of three (3) or more
	    members of the Board who are not employees of the Company, none of
	    whom shall be eligible to participate in the Plan and all of whom
	    shall be  disinterested persons  as defined under Rule 16b-3.  The
	    Stock Option Committee shall be appointed by and shall serve at
	    the pleasure of the Board.  Subject to the provisions of this
	    Plan, said Committee shall have full power to construe and
	    interpret the Plan and to establish, amend and rescind rules and
	    regulations for its administration.


6.          Eligible Employees.   Options may be granted to such key employees
	    of the Company or of any of its subsidiaries, including members of
	    the Board who are also employees of the Company or any of its
	    subsidiaries, as are selected by the Stock Option Committee.


7.          Duration of the Plan.   This Plan shall terminate on December 31,
	    2003, unless terminated earlier pursuant to Paragraph 13
	    hereafter, and no options may be granted thereafter.


8.          Restrictions on Incentive Options.   Incentive options (but not
	    nonqualified options) granted under this Plan shall be subject to
	    the following  restrictions:

	    (a)   Limitation on Number of Shares.   (i)  With respect to
		  incentive options granted  before January 1, 1987, the
		  aggregate fair market value, determined as of the date the
		  incentive option is granted, of the Shares for which an
		  employee may be granted incentive  option in any calendar
		  year shall not exceed $100,000 plus  any "unused  limit 
		  carryovers," as that term is defined under Section 
		  422A(c)(4)  of the Code (as  in  effect immediately prior to
		  its amendment by the Tax Reform Act of 1986),  available in
		  such year;  or  (ii) for incentive options granted after
		  December  31, 1986, the aggregate fair market value,
		  determined as of the date the incentive option is granted,
		  of the Shares with respect to which incentive options are
		  exercisable for the first time by an employee during any
		  calendar year shall not exceed $100,000.   In the event that
		  an employee is eligible to participate in any other
		  incentive stock option plans of the Company or any of its
		  subsidiaries which are also intended to comply with the
		  provisions of Section 422 of the Code, the applicable annual
		  limitation shall apply to the aggregate number of Shares for
		  which incentive stock options may be granted under all such
		  plans.


	  (b)   10% Stockholder.   If any employee to whom an incentive
		  option is granted pursuant to the provisions of the Plan is
		  on the date of grant  the owner of stock (as determined
		  under Section 424(d) of the Code) possessing more than 10%
		  of the total combined voting power of all classes of stock
		  of the Company or any of its subsidiaries, then the
		  following special provisions shall be applicable to the
		  incentive option granted to such individual:

	    (i)   The option price per Share subject to such incentive option
		  shall not be less than 110% of the fair market value of one
		  Share on the date of grant; and The incentive option shall
		  not have a term in excess of five (5) years from the date of
		  grant.

	    (c)   Effect of Other Outstanding Incentive Options.   No
		  incentive option granted before January 1, 1987 hereunder
		  shall be exercisable by any optionee while there is
		  "outstanding," within the meaning of Section 422A(c)(7) of
		  the Code (as in effect immediately prior to its amendment by
		  the Tax Reform Act of 1986), any incentive option or other
		  incentive stock option which was granted to the optionee
		  before the granting of the incentive option under this Plan
		  and which permits the optionee to purchase stock in (i) the
		  Company, (ii) a corporation which (at the time of the 
		  granting of the incentive option under this Plan) is a
		  parent or subsidiary of the Company, or (iii) a predecessor
		  corporation of any of such corporations.

9.          Terms and Conditions of Options.   Options granted under this Plan
	    shall be evidenced by stock option agreements in such form and not
	    inconsistent with the Plan as the Stock Option Committee shall
	    approve from time to time, which agreements shall evidence the
	    following terms and conditions:

	    (a)         Price.   Subject to the condition of subparagraph
		  (b)(i) of Paragraph 8, if applicable, with respect to each
		  incentive option, the purchase price per Share of stock
		  payable upon the exercise of each option granted hereunder
		  shall be not less than 100% of the fair market value of the
		  stock on the day the option is granted.   With respect to
		  each nonqualified option, the purchase price per Share
		  payable upon the exercise of each option granted hereunder
		  shall be determined by the Stock Option Committee at the
		  time the option is granted and shall not be less than 50% of
		  the fair market value of one Share on the date of grant.

	    (b)   Number of Shares.   Each option agreement shall specify the
		  number of Shares to which it pertains.

	    (c)         Exercise of Options.   Subject to the conditions on
		  incentive options of subparagraph (b)(ii) and (c) of
		  Paragraph 8, if applicable, each option shall be exercisable
		  for the full amount or for any part thereof and at such
		  intervals or in such installments as the Stock Option
		  Committee may determine at the time it grants such option; 
		  provided, however, that no option shall be exercisable with
		  respect to any Shares later than ten (10) years after the
		  date of the grant of such option.

	    (d)         Notice of Exercise and Payment.   An option shall be
		  exercisable only by delivery of a written notice to the
		  Stock Option Committee, any member of the Committee, the
		  Company's Treasurer, or any other officer of the Company
		  designated by the Committee to accept such notices on its
		  behalf, specifying the number of Shares for which it is
		  exercised.   If said Shares are not at the time effectively
		  registered under the Securities Act of 1933, as amended, the
		  optionee shall include with such notice a letter, in form
		  and substance satisfactory to the Company, confirming that
		  the Shares are being  purchased for the optionee's own
		  account for investment and not with a view to distribution.  
		  Payment shall be made in full at the time of delivery to the
		  optionee of a certificate or certificates covering the
		  number of Shares for which  the option was exercised. 
		  Payment shall be made (i) by cash or check, (ii) if
		  permitted by the Stock Option Committee, by delivery and
		  assignment to the Company of Shares of Company stock having
		  a fair market value (as determined by the Stock Option
		  Committee) equal to the option price,  (iii) [only with
		  respect to optionees who are officers or directors of the
		  Company (or its affiliates) who, by reason of their
		  relationship to the Company, would be subject to Section 16
		  of the Securities Exchange Act of 1934, as amended in
		  connection with their acquisition or disposition of Common
		  Stock of the Company (a "Section 16 Person")], if permitted
		  by the Stock Option Committee, by promissory note, or (iv)
		  by a combination of (i), (ii) and (iii) (if applicable).  
		  The value of the Company stock for such purpose shall be its
		  fair market value as of the date the option is exercised, as
		  determined in accordance with procedures to be established
		  by the Stock Option  Committee.

	     (e)        Withholding Taxes;  Delivery of Shares.  The Company's
		  obligation to deliver Shares of Common Stock upon exercise
		  of a nonqualified option, in whole or in part, shall be
		  subject to the optionee's satisfaction of all applicable
		  federal, state and local income and employment tax
		  withholding obligations.   The optionee may satisfy the
		  obligation, in whole or in part, by electing to have the
		  Company withhold Shares of Common Stock having a value equal
		  to the amount required to be withheld.   The value of Shares
		  to be withheld shall be based on the fair market value of
		  the Shares on the date the amount of tax to be withheld is
		  to be determined (the "Tax  Date").  The optionee's election
		  to have Shares withheld for this purpose will be subject to
		  the following restrictions:   (1) the election must be made
		  prior to the Tax Date,  (2) the election must be
		  irrevocable,  (3) the election will be subject to the right
		  of the Committee to disapprove the election, and (4) if a
		  participant is a  Section 16 Person, such election must
		  comply in all respects with the requirements of Rule 16b-3.

	    (f)         Non-Transferability.  No option shall be transferable
		  by the optionee otherwise than by will or the laws of
		  descent or distribution, and each option shall be
		  exercisable during his lifetime only by him.

	    (g)         Termination  of Options.  Each option shall terminate
		  and may no longer be exercised if the optionee ceases for
		  any reason to be a employee of the Company, or its parent or
		  a subsidiary, except that:

		  (i)   if the optionee's employment shall have terminated for
			any reason other than cause, disability (as  defined
			below) or death, he may at any time within a period of
			thirty (30) days after such termination of employment
			exercise his option to the extent that the option was
			exercisable by him on the date of termination of his
			employment;

	    (ii)  if the optionee's employment shall have been terminated
		  because of disability within the meaning of Section 22(e)(3)
		  of the Code, with respect to incentive options granted to
		  the  optionee, the optionee  may, at any time within a
		  period of one  (1)  year after such termination of
		  employment, and with respect to nonqualified options granted
		  to the optionee, the optionee may, at any time within a
		  period of one year and one  day after such termination of
		  employment, exercise his option to the extent that the
		  option was exercisable by him on the date of termination of
		  his employment;  and

	    (iii) if the optionee dies at a time when the option was
		  exercisable by him, then his estate, personal representative
		  or beneficiary to whom it has been transferred pursuant to
		  paragraph 9(f) hereof may exercise the option to the extent
		  the optionee might have exercised it at the time of his
		  death; (a) at any time within a period of six (6) months
		  following his death if the optionee was not an employee at
		  the time of his death, or, (b) in the event his employment
		  with the Company is terminated by his death, one (1) year
		  following such termination of employment.  In no case,
		  however, may an option be exercised to any extent by anyone
		  after the date of expiration of the option.

	    (h)         Rights as Shareholder.  The optionee shall have no
		  rights as a shareholder with respect to any Shares covered
		  by his option until the date of issuance of a stock
		  certificate to him for such  Shares.

10.         Stock Dividends; Stock Splits; Stock Combinations;
	    Recapitalizations.   Appropriate adjustment shall be made in the
	    maximum number of Shares of Common Stock subject to the Plan and
	    in the number, kind, and option price of Shares covered by
	    outstanding options granted hereunder to give effect to any stock
	    dividends or other distribution (which exceeds five percent of the
	    total number of Shares of Common Stock outstanding at the close of
	    business on the date fixed for the determination of stockholders
	    entitled to receive such stock  dividend or distribution), stock
	    splits, stock combinations, recapitalizations and other similar
	    changes in the capital structure of the Company after the
	    effective date of the Plan.

11.         Merger; Sale of Assets; Dissolution.  In the event of a change of
	    the Common  Stock resulting from a merger or similar
	    reorganization as to which the Company is the surviving
	    corporation, the number and kind of Shares which thereafter may be
	    optioned and sold under this Plan and the number and kind of
	    Shares then subject to options granted hereunder and the price per
	    share thereof shall be appropriately adjusted in such manner as
	    the Stock Option Committee may deem equitable to prevent
	    substantial dilution or enlargement of the rights available or
	    granted hereunder.   Except as otherwise determined by the Board,
	    a merger or a similar reorganization which the Company does not
	    survive, or a sale of all or substantially all of the assets of
	    the Company, shall cause every option outstanding hereunder to
	    terminate, to the extent not then exercised, unless any surviving
	    entity agrees to assume the obligations hereunder.

12.         Definitions.

	    (a)   The term "key employees" means those executive,
		  administrative, operational or managerial employees who are
		  determined by the Stock Option Committee to be eligible for
		  options under this Plan.

	    (b)   The term "option", unless otherwise indicated, means either
		  an incentive  option or a nonqualified option.   The term
		  "options" refers to both incentive options or nonqualified
		  options.

	    (c)   The term "optionee" means a key employee to whom an option
		  is granted under this Plan.

	    (d)   The term "parent" shall have, for purposes of this Plan, the
		  meaning ascribed to it under Section 424(e) of the Code.

	    (e)   The term "subsidiary  shall, for purposes of this Plan, have
		  the meaning ascribed to it under Section 424(f) of the Code.

13.         Termination or Amendment of Plan.  The Board may at any time
	    terminate this Plan or make such changes in or additions to the
	    Plan as it deems advisable without further action on the part of
	    the shareholders of the Company, provided:

	    (a)   that no such termination or amendment shall adversely affect
		  or impair any then outstanding option without the consent of
		  the optionee holding such option;  and

	    (b)   that any such amendment which:
		  
		  (i)   increases the maximum number of Shares subject to this
			Plan (subject to the provisions of Section 10),

		  (ii)  changes the class of persons eligible to participate
			in this Plan, or

		  (iii) materially increases the benefits accruing to
			participants under this Plan; shall be subject to
			approval by the shareholders of the Company within one
			(1) year from the effective date of such amendment and
			shall be null and void if such approval is not
			obtained.
