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


                           HAEMONETICS CORPORATION

                           1998 STOCK OPTION PLAN

                         FOR NON-EMPLOYEE DIRECTORS

      1.  PURPOSE
          -------

      The purpose of this Haemonetics Corporation 1998 Stock Option Plan for 
Non-Employee Directors (the "Plan") is to attract and retain the services of 
experienced and knowledgeable independent directors who are not employees 
(sometimes referred to herein collectively as "Participants") of Haemonetics 
Corporation ("Haemonetics" or the "Company") or its subsidiaries for the 
benefit of Haemonetics and its stockholders and to provide additional 
incentive for such Participants to continue to work in the best interests of 
Haemonetics and its stockholders through continuing ownership of its common 
stock.

      2.  SHARES SUBJECT TO THE PLAN
          --------------------------

      The total number of shares of common stock, par value $.01 per share 
of Haemonetics ("Common Stock") available for stock options granted under 
this Plan shall not exceed 500,000  shares in the aggregate, subject to 
adjustment in accordance with Section 12 hereof.  Shares issued under the 
Plan may be authorized but unissued shares of Common Stock or shares of 
Common Stock held in treasury.  Options granted pursuant to the Plan shall 
be authorized by action of the Board of Directors.  Stock issuable upon the 
exercise of an option granted under the Plan may be subject to such 
restrictions on transfer, repurchase rights or other restrictions as shall 
be determined by the Board of Directors.

      3.  ADMINISTRATION OF THE PLAN
          --------------------------

      The Plan shall be administered by the Board of Directors.  The Board 
shall, subject to the provisions of this Plan, have the power to construe 
this Plan, to determine all questions of interpretation and application of 
the Plan and to adopt and amend such rules and regulations for the 
administration of the Plan as the Board may deem desirable.  No member of 
the Board shall be liable for any action or determination made in good faith 
with respect to this Plan or any option granted under it.

      4.  ELIGIBILITY
          -----------

      Members of the Board of Directors of Haemonetics who are not employees 
of Haemonetics or its subsidiaries are eligible to be granted options under 
the Plan.

      5.  OPTION AGREEMENT
          ----------------

      Each option granted under the Plan shall be evidenced by an option 
agreement (the "Agreement") duly executed on behalf of Haemonetics and by 
the director to whom such option is granted, which Agreements shall (i) 
comply with and be subject to the terms and conditions of the Plan and (ii) 
provide that the optionee agrees to continue to serve as a director of 
Haemonetics, during the term for which he or she was elected.

      6.  OPTION EXERCISE PRICE
          ---------------------

      Subject to the provisions of Section 10 hereof, the option exercise 
price for an option granted under the Plan shall be the fair market value of 
the shares of the Common Stock of Haemonetics covered by the option on the 
date of grant of the option.  For the purposes hereof and Section 7, the 
fair market value of the Common Stock of Haemonetics shall be the mean 
between the high and low sales prices of the Common Stock of Haemonetics on 
the New York Stock Exchange ("NYSE") on the date of grant, or (if the Common 
Stock of Haemonetics did not trade on such date) on the most recent date 
prior to the date of grant on which such trading occurred.

      7.  TIME AND MANNER OF EXERCISE OF OPTIONS
          --------------------------------------

      Each option granted under the Plan shall, subject to Section 8 and 
Section 10 hereof, be exercisable at such time or times and during such 
period as is determined by the Board of Directors and set forth in the 
Agreement; provided, however, that no option granted under the Plan shall 
have a term in excess of ten (10) years from the date of grant.  To the 
extent that the right to exercise an option has accrued and is in effect, 
the option may be exercised in full at one time or in part from time to time 
by giving written notice, signed by the person or persons exercising the 
option, to Haemonetics, stating the number of shares with respect to which 
the option is being exercised, accompanied by payment in full for such 
shares, which payment may be in cash or in whole or in part in shares of the 
Common Stock of Haemonetics already owned for a period of at least six 
months by the person or persons exercising the option, valued at fair market 
value, as determined under Section 6 hereof, on the date of exercise.  Upon 
such exercise, delivery of a certificate for paid-up non-assessable shares 
shall be made as promptly as practicable at the principal office of 
Haemonetics to the person or persons exercising the option.

      8.  TERM OF OPTIONS
          ---------------

      (a)  Each option shall expire ten (10) years from the date of the 
granting thereof, but shall be subject to earlier termination as herein 
provided.

      (b)  In the event of the death of an optionee, the option granted to 
such optionee may be exercised, to the extent the optionee was entitled to 
do so on the date of such optionee's death, by the estate of such optionee 
or by any person or persons who acquired the right to exercise such option 
by bequest or inheritance or otherwise by reason of the death of such 
optionee.  Such option may be exercised at any time within one (1) year 
after the date of death of such optionee, at which time the option shall 
terminate, or prior to the date on which the option otherwise expires by its 
terms, whichever is earlier.

      (c)  In the event that an optionee ceases to be a director of 
Haemonetics, the option granted to such optionee may be exercised by him or 
her, but only to the extent that under Section 7 hereof the right to 
exercise the option has accrued and is in effect.  Such option may be 
exercised at any time within three (3) months after the date such optionee 
ceases to be a director of Haemonetics, at which time the option shall 
terminate, but in any event prior to the date on which the option expires by 
its terms, whichever is earlier, unless termination as a director, (a) was 
by Haemonetics for cause, in which case the option shall terminate 
immediately at the time the optionee ceases to be a director of Haemonetics, 
(b) was because the optionee has become disabled (within the meaning of 
Section 22(e)(3) of the Code), or (c) was by reason of the death of the 
optionee.  In the case of death, see Section 8(b) above.  In the case of 
disability, the option may be exercised, to the extent then exercisable 
under Section 7 hereof, at any time within one (1) year after the date of 
termination of the optionee's directorship with Haemonetics, at which time 
the option shall terminate, but in any event prior to the date on which the 
option otherwise expires by its terms, whichever is earlier.

      9.  OPTIONS NOT TRANSFERABLE
          ------------------------

      The right of any optionee to exercise an option granted to him or her 
under the Plan shall not be assignable or transferable by such optionee 
otherwise than by will or the laws of descent and distribution, or pursuant 
to a qualified domestic relations order as defined by the Code or Title I of 
the Employee Retirement Income Security Act, or the rules thereunder.  Any 
option granted under the Plan shall be exercisable during the lifetime of 
such optionee only by him or her.  Any option granted under the Plan shall 
be null and void and without effect upon any attempted assignment or 
transfer, except as herein provided, including without limitation any 
purported assignment, whether voluntary or by operation of law, pledge, 
hypothecation or other disposition, attachment, trustee process or similar 
process, whether legal or equitable, upon such option.

      10.  RECAPITALIZATIONS, REORGANIZATIONS AND THE LIKE
           -----------------------------------------------

      (a)  In the event that the outstanding shares of the Common Stock of 
the Company are changed into or exchanged for a different number or kind of 
shares or other securities of the Company or of another corporation by 
reason of any reorganization, merger, consolidation, recapitalization, 
reclassification, stock split-up, combination of shares, or dividends 
payable in capital stock, appropriate adjustment shall be made in the number 
and kind of shares as to which options may be granted under the Plan and as 
to which outstanding options or portions thereof then unexercised shall be 
exercisable, to the end that the proportionate interest of the optionee 
shall be maintained as before the occurrence of such event; such adjustment 
in outstanding options shall be made without change in the total price 
applicable to the unexercised portion of such options and with a 
corresponding adjustment in the option price per share.

      (b)  In addition, unless otherwise determined by the Board in its sole 
discretion, in the case of any (i) sale or conveyance to another entity of 
all or substantially all of the property and assets of the Company or (ii) 
Change in Control (as hereinafter defined) of the Company, the purchaser(s) 
of the Company's assets or stock may, in his, her or its discretion, deliver 
to the optionee the same kind of consideration that is delivered to the 
shareholders of the Company as a result of such sale, conveyance or Change 
in Control, or the Board may cancel all outstanding options in exchange for 
consideration in cash or in kind which consideration in both cases shall be 
equal in value to the value of those shares of stock or other securities the 
optionee would have received had the option been exercised (to the extent 
then exercisable) and no disposition of the shares acquired upon such 
exercise been made prior to such sale, conveyance or Change in Control, less 
the option price therefor.  Upon receipt of such consideration by the 
optionee, his or her option shall immediately terminate and be of no further 
force and effect.  The value of the stock or other securities the optionee 
would have received if the option had been exercised shall be determined in 
good faith by the Board, and in the case of shares of the Common Stock of 
the Company, in accordance with the provisions of Section 6 hereof.  The 
Board shall also have the power and right to accelerate the exercisability 
of any options, notwithstanding any limitations in this Plan or in the 
Agreement upon such a sale, conveyance or Change in Control.  A "Change in 
Control" shall be deemed to have occurred if any person, or any two or more 
persons acting as a group, and all affiliates of such person or persons, who 
prior to such time owned less than thirty five percent (35%) of the then 
outstanding Common Stock of the Company, shall acquire such additional 
shares of the Company's Common Stock in one or more transactions, or series 
of transactions, such that following such transaction or transactions, such 
person or group and affiliates beneficially own thirty five percent (35%) or 
more of the Company's Common Stock outstanding.

      (c)  Upon dissolution or liquidation of the Company, all options 
granted under this Plan shall terminate, but each optionee (if at such time 
associated with the Company or any of its subsidiaries) shall have the 
right, immediately prior to such dissolution or liquidation, to exercise his 
or her option to the extent then exercisable.

      (d)  No fraction of a share shall be purchasable or deliverable upon 
the exercise of any option, but in the event any adjustment hereunder of the 
number of shares covered by the option shall cause such number to include a 
fraction of a share, such number shall be adjusted to the nearest smaller 
whole number of shares.

      11.  RESTRICTIONS ON ISSUE OF SHARES
           -------------------------------

      Notwithstanding the provisions of Section 7 hereof, Haemonetics may 
delay the issuance of shares covered by the exercise of any option and the 
delivery of a certificate for such shares until one of the following 
conditions shall be satisfied:

      (i)  the shares with respect to which an option has been exercised are 
at the time of the issue of such shares effectively registered under 
applicable Federal and state securities acts now in force or hereafter 
amended; or

      (ii)  counsel for Haemonetics shall have given an opinion, which 
opinion shall not be unreasonably conditioned or withheld, that such shares 
are exempt from registration under applicable Federal and state securities 
acts now in force or hereafter amended.

      It is intended that all exercises of options shall be effective.  
Accordingly, Haemonetics shall use its best efforts to bring about 
compliance with the above conditions within a reasonable time, except that 
Haemonetics shall be under no obligation to cause a registration statement 
or a post-effective amendment to any registration statement to be prepared 
at its expense solely for the purpose of covering the issue of shares in 
respect of which any option may be exercised, except as otherwise agreed to 
by Haemonetics in writing.

      12.  RIGHTS OF HOLDER ON PURCHASE FOR INVESTMENT; SUBSEQUENT REGISTRATION
           --------------------------------------------------------------------

      Unless the shares to be issued upon exercise of an option granted 
under the Plan have been effectively registered under the Securities Act of 
1933, as now in force or hereafter amended, Haemonetics shall be under no 
obligation to issue any shares covered by any option unless the person who 
exercises such option, in whole or in part, shall give a written 
representation and undertaking to Haemonetics which is satisfactory in form 
and scope to counsel to Haemonetics and upon which, in the opinion of such 
counsel, Haemonetics may reasonably rely, that he or she is acquiring the 
shares issued pursuant to such exercise of the option for his or her own 
account as an investment and not with a view to, or for sale in connection 
with, the distribution of any such shares, and that he or she will make no 
transfer of the same except in compliance with any rules and regulations in 
force at the time of such transfer under the Securities Act of 1933, or any 
other applicable law, and that if shares are issued without such 
registration a legend to this effect may be endorsed upon the securities so 
issued.  In the event that Haemonetics shall, nevertheless, deem it 
necessary or desirable to register under the Securities Act of 1933 or other 
applicable statutes any shares with respect to which an option shall have 
been exercised, or to qualify any such shares for exemption from the 
Securities Act of 1933 or other applicable statutes, then Haemonetics shall 
take such action at its own expense and may require from each optionee such 
information in writing for use in any registration statement, prospectus, 
preliminary prospectus or offering circular as is reasonably necessary for 
such purpose and may require reasonable indemnity to Haemonetics and its 
officers and directors from such holder against all losses, claims, damages 
and liabilities arising from such use of the information so furnished and 
caused by any untrue statement of any material fact therein or caused by the 
omission to state a material fact required to be stated therein or necessary 
to make the statements therein not misleading in light of the circumstances 
under which they were made.

      13.  APPROVAL OF STOCKHOLDERS
           ------------------------

      The Plan shall be subject to approval by the vote of stockholders 
holding at least a majority of the voting stock of Haemonetics voting in 
person or by proxy at a duly held stockholders' meeting, or by written 
consent of all of the stockholders, and shall take effect immediately as of 
its date of adoption upon such approval.

      14.  EXPENSES OF THE PLAN
           --------------------

      All costs and expenses of the adoption and administration of the Plan 
shall be borne by Haemonetics, and none of such expenses shall be charged to 
any optionee.

      15.  TERMINATION AND AMENDMENT OF PLAN
           ---------------------------------

      Unless sooner terminated as herein provided, the Plan shall terminate 
ten (10) years from the date upon which the Plan was duly approved by the 
Board.  The Board may at any time terminate this Plan or make such 
modification or amendment thereof as it deems advisable. 

      16.  LIMITATION OF RIGHTS IN THE OPTION SHARES
           -----------------------------------------

      An optionee shall not be deemed for any purpose to be a stockholder of 
Haemonetics with respect to any of the options except to the extent that the 
option shall have been exercised with respect thereto and, in addition, a 
certificate shall have been issued theretofore and delivered to the 
optionee.

      17.  NOTICES
           -------

      Any communication or notice required or permitted to be given under 
the Plan shall be in writing, and mailed by registered or certified mail or 
delivered by hand, if to Haemonetics, to its principal place of business, 
attention:  General Counsel, and, if to an optionee, to the address as 
appearing on the records of Haemonetics.
