ENZO BIOCHEM, INC.

                             1994 STOCK OPTION PLAN


1.        PURPOSE.

          The purpose of this plan (the "Plan") is to secure for Enzo Biochem,
Inc. (the "Company") and its shareholders the benefits arising from capital
stock ownership by employees, officers and directors of, and consultants or
advisors to, the Company and its subsidiary corporations who are expected to
contribute to the Company's future growth and success.  Those provisions of the
Plan which make express reference to Section 422 shall apply only to Incentive
Stock Options (as that term is defined in the Plan).

2.        TYPE OF OPTIONS AND ADMINISTRATION.

          (a)  TYPES OF OPTIONS.  Options granted pursuant to the Plan shall be
authorized by action of the Board of Directors of the Company (or a Committee
designated by the Board of Directors) and may be either incentive stock options
("Incentive Stock Options") meeting the requirements of Section 422 of the
Internal Revenue Code of 1986, as amended or replaced from time to time (the
"Code") or non-statutory options which are not intended to meet the requirements
of Section 422 of the Code.

          (b)  ADMINISTRATION.  The Plan will be administered by a committee
(the "Committee") appointed by the Board of Directors of the Company, whose
construction and interpretation of the terms and provisions of the Plan shall be
final and conclusive.  The delegation of powers to the Committee shall be
consistent with applicable laws or regulations (including, without limitation,
applicable state law and Rule 16b-3 promulgated under the Securities Exchange
Act of 1934 (the "Exchange Act"), or any successor rule ("Rule 16b-3")).  The
Committee may in its sole discretion grant options to purchase shares of the
Company's Common Stock, $.01 par value per share ("Common Stock") and issue
shares upon exercise of such options as provided in the Plan.  The Committee
shall have authority, subject to the express provisions of the Plan, to construe
the respective option agreements and the Plan, to prescribe, amend and rescind
rules and regulations relating to the Plan, to determine the terms and
provisions of the respective option agreements, which need not be identical, and
to make all other determinations in the judgment of the Committee necessary or
desirable for the administration of the Plan.  The Committee may correct any
defect or supply any omission or reconcile any inconsistency in the Plan or in
any option agreement in the manner and to the extent it shall deem expedient to
carry the Plan into effect and it shall be the sole and final judge of such
expediency.  No director or person acting pursuant to authority delegated by the
Board of Directors shall be liable for any action or determination under the
Plan made in good faith.  Subject to adjustment as provided in Section 15 below,
the aggregate number of shares of Common Stock that may be subject to options
granted to any person in a calendar year shall not exceed 20% of the maximum


number of shares which may be issued and sold under the Plan, as set forth in
Section 4 hereof, as such section may be amended from time to time.

          (c)  APPLICABILITY OF RULE 16B-3.  Those provisions of the Plan which
make express reference to Rule 16b-3 shall apply to the Company only at such
time as the Company's Common Stock is registered under the Exchange Act, subject
to the last sentence of Section 3(b), and then only to such persons as are
required to file reports under Section 16(a) of the Exchange Act (a "Reporting
Person").

3.        ELIGIBILITY.

          (a)  GENERAL.  Options may be granted to persons who are, at the time
of grant, employees, officers or directors of, or consultants or advisors to,
the Company or any subsidiaries of the Company as defined in Sections 424(e) and
424(f) of the Code ("Participants") PROVIDED, that Incentive Stock Options may
only be granted to individuals who are employees of the Company (within the
meaning of Section 3401(c) of the Code).  A person who has been granted an
option may, if he or she is otherwise eligible, be granted additional options if
the Committee shall so determine.

          (b)  GRANT OF OPTIONS TO REPORTING PERSONS.  The selection of a
director or an officer who is a Reporting Person (as the terms "director" and
"officer" are defined for purposes of Rule 16b-3) as a recipient of an option,
the timing of the option grant, the exercise price of the option and the number
of shares subject to the option shall be determined either (i) by the Board of
Directors, of which all members shall be "disinterested persons" (as hereinafter
defined), (ii) by a committee consisting of two or more directors having full
authority to act in the matter, each of whom shall be a "disinterested person"
or (iii) pursuant to provisions for automatic grants set forth in Section 3(c)
below.  For the purposes of the Plan, a director shall be deemed to be a
"disinterested person" only if such person qualifies as a "disinterested person"
within the meaning of Rule 16b-3, as such term is interpreted from time to time.
If at least two of the members of the Board of Directors do not qualify as a
"disinterested person" within the meaning of Rule 16b-3, as such term is
interpreted from time to time, then the granting of options to officers and
directors who are Reporting Persons under the Plan shall not be determined in
accordance with this Section 3(b) but shall be determined in accordance with the
other provisions of the Plan.

          (c)  DIRECTORS' OPTIONS.  Commencing on June 30, 1995, directors of
the Company who are not employees or principal stockholders of the Company
("Eligible Directors") will receive an option ("Director Option") to purchase
7,500 shares of Common Stock.  Commencing July 19, 1995, future Eligible
Directors of the Company will be granted a Director Option to purchase 15,000
shares of Common Stock on the date that such person is first elected or
appointed a director ("Initial Director Option").  Commencing on the day
immediately following the date of the annual meeting of stockholders for the
Company's fiscal year ending July 31, 1995, each Eligible Director will receive
an automatic grant


                                       -2-


("Automatic Grant") of a Director Option to purchase 7,500 shares of Common
Stock, other than Eligible Directors who received an Initial Director Option
since the most recent Automatic Grant, on the day immediately following the date
of each annual meeting of stockholders, as long as such director is a member of
the Board of Directors.  The exercise price for each share subject to a Director
Option shall be equal to the fair market value of the Common Stock on the date
of grant.  Director Options shall become exercisable in four equal annual
installments commencing one year from the date the option is granted and will
expire the earlier of 10 years after the date of grant or 90 days after the
termination of the director's service on the Board unless such Director Option
is an Incentive Stock Option in which case such Director Option shall be subject
to the additional terms and conditions set forth in Section 11.

4.        STOCK SUBJECT TO PLAN.

          The stock subject to options granted under the Plan shall be shares of
authorized but unissued or reacquired Common Stock.  Subject to adjustment as
provided in Section 15 below, the maximum number of shares of Common Stock of
the Company which may be issued and sold under the Plan is 950,000 shares.  If
an option granted under the Plan shall expire, terminate or is cancelled for any
reason without having been exercised in full, the unpurchased shares subject to
such option shall again be available for subsequent option grants under the
Plan.

5.        FORMS OF OPTION AGREEMENTS.

          As a condition to the grant of an option under the Plan, each
recipient of an option shall execute an option agreement in such form not
inconsistent with the Plan as may be approved by the Board of Directors.  Such
option agreements may differ among recipients.

6.        PURCHASE PRICE.

          (a)  GENERAL.  The purchase price per share of stock deliverable upon
the exercise of an option shall be determined by the Board of Directors at the
time of grant of such option; PROVIDED, HOWEVER, that in the case of an
Incentive Stock Option, the exercise price shall not be less than 100% of the
Fair Market Value (as hereinafter defined) of such stock, at the time of grant
of such option, or less than 110% of such Fair Market Value in the case of
options described in Section 11(b).  "Fair Market Value" of a share of Common
Stock of the Company as of a specified date for the purposes of the Plan shall
mean the closing price of a share of the Common Stock on the principal
securities exchange (including the Nasdaq National Market) on which such shares
are traded on the day immediately preceding the date as of which Fair Market
Value is being determined, or on the next preceding date on which such shares
are traded if no shares were traded on such immediately preceding day, or if the
shares are not traded on a securities exchange, Fair Market Value


                                       -3-


shall be deemed to be the average of the high bid and low asked prices of the
shares in the over-the-counter market on the day immediately preceding the date
as of which Fair Market Value is being determined or on the next preceding date
on which such high bid and low asked prices were recorded.  If the shares are
not publicly traded, Fair Market Value of a share of Common Stock (including, in
the case of any repurchase of shares, any distributions with respect thereto
which would be repurchased with the shares) shall be determined in good faith by
the Board of Directors.  In no case shall Fair Market Value be determined with
regard to restrictions other than restrictions which, by their terms, will never
lapse.

          (b)  PAYMENT OF PURCHASE PRICE.  Options granted under the Plan may
provide for the payment of the exercise price by delivery of cash or a check to
the order of the Company in an amount equal to the exercise price of such
options, or by any other means which the Board of Directors determines are
consistent with the purpose of the Plan and with applicable laws and regulations
(including, without limitation, the provisions of Rule 16b-3 and Regulation T
promulgated by the Federal Reserve Board).

7.        OPTION PERIOD.

          Subject to earlier termination as provided in the Plan, each option
and all rights thereunder shall expire on such date as determined by the Board
of Directors and set forth in the applicable option agreement, PROVIDED, that
such date shall not be later than (10) ten years after the date on which the
option is granted.

8.        EXERCISE OF OPTIONS.

          Each option granted under the Plan shall be exercisable either in full
or in installments at such time or times and during such period as shall be set
forth in the option agreement evidencing such option, subject to the provisions
of the Plan.  No option granted to a Reporting Person for purposes of the
Exchange Act, however, shall be exercisable during the first six months after
the date of grant.  Subject to the requirements in the immediately preceding
sentence, if an option is not at the time of grant immediately exercisable, the
Board of Directors may (i) in the agreement evidencing such option, provide for
the acceleration of the exercise date or dates of the subject option upon the
occurrence of specified events, and/or (ii) at any time prior to the complete
termination of an option, accelerate the exercise date or dates of such option.

9.        NONTRANSFERABILITY OF OPTIONS.

          No option granted under this Plan shall be assignable or otherwise
transferable by the optionee except by will or by the laws of descent and
distribution or pursuant to a qualified domestic relations order as defined in
the Code or Title I of the Employee Retirement Income Security Act, or the rules
thereunder.  An option may be exercised during the lifetime of the optionee only
by the optionee.  In the event an optionee dies during


                                       -4-


his employment by the Company or any of its subsidiaries, or during the
three-month period following the date of termination of such employment, his
option shall thereafter be exercisable, during the period specified in the
option agreement, by his executors or administrators to the full extent to which
such option was exercisable by the optionee at the time of his death during the
periods set forth in Section 10 or 11(d).

10.       EFFECT OF TERMINATION OF EMPLOYMENT OR OTHER RELATIONSHIP.

          Except as provided in Section 11(d) with respect to Incentive Stock
Options and except as otherwise determined by the Committee at the date of grant
of an option, and subject to the provisions of the Plan, an optionee may
exercise an option at any time within three (3) months following the termination
of the optionee's employment or other relationship with the Company or within
three (3) months if such termination was due to the death or disability of the
optionee or within one (1) year if such termination was due to the disability of
the optionee but, except in the case of the optionee's death, in no event later
than the expiration date of the option.  If the termination of the optionee's
employment is for cause or is otherwise attributable to a breach by the optionee
of an employment or confidentiality or non-disclosure agreement, the option
shall expire immediately upon such termination.  The Board of Directors shall
have the power to determine what constitutes a termination for cause or a breach
of an employment or confidentiality or non-disclosure agreement, whether an
optionee has been terminated for cause or has breached such an agreement, and
the date upon which such termination for cause or breach occurs.  Any such
determinations shall be final and conclusive and binding upon the optionee.

11.       INCENTIVE STOCK OPTIONS.

          Options granted under the Plan which are intended to be Incentive
Stock Options shall be subject to the following additional terms and conditions:

          (a)  EXPRESS DESIGNATION.  All Incentive Stock Options granted under
the Plan shall, at the time of grant, be specifically designated as such in the
option agreement covering such Incentive Stock Options.

          (b)  10% SHAREHOLDER.  If any employee to whom an Incentive Stock
Option is to be granted under the Plan is, at the time of the grant of such
option, the owner of stock possessing more than 10% of the total combined voting
power of all classes of stock of the Company (after taking into account the
attribution of stock ownership rules of Section 424(d) of the Code), then the
following special provisions shall be applicable to the Incentive Stock Option
granted to such individual:

               (i)   The purchase price per share of the Common Stock subject to
          such Incentive Stock Option shall not be less than 110% of the Fair
          Market Value of one share of Common Stock at the time of grant; and


                                       -5-


               (ii)  the option exercise period shall not exceed five years from
          the date of grant.

          (c)  DOLLAR LIMITATION.  For so long as the Code shall so provide,
options granted to any employee under the Plan (and any other incentive stock
option plans of the Company) which are intended to constitute Incentive Stock
Options shall not constitute Incentive Stock Options to the extent that such
options, in the aggregate, become exercisable for the first time in any one
calendar year for shares of Common Stock with an aggregate Fair Market Value, as
of the respective date or dates of grant, of more than $100,000.

          (d)  TERMINATION OF EMPLOYMENT, DEATH OR DISABILITY.  No Incentive
Stock Option may be exercised unless, at the time of such exercise, the optionee
is, and has been continuously since the date of grant of his or her option,
employed by the Company, except that:

               (i)   an Incentive Stock Option may be exercised within the
          period of ninety (90) days after the date the optionee ceases to be an
          employee of the Company (or within such lesser period as may be
          specified in the applicable option agreement), PROVIDED, that the
          agreement with respect to such option may designate a longer exercise
          period and that the exercise after such ninety  (90) day period shall
          be treated as the exercise of a non-statutory option under the Plan;

               (ii)  if the optionee dies while in the employ of the Company, or
          within three months after the optionee ceases to be such an employee,
          the Incentive Stock Option may be exercised by the person to whom it
          is transferred by will or the laws of descent and distribution within
          the period of three (3) months after the date of death (or within such
          lesser period as may be specified in the applicable option agreement);
          and

               (iii)  if the optionee becomes disabled (within the meaning of
          Section 22(e)(3) of the Code or any successor provisions thereto)
          while in the employ of the Company, the Incentive Stock Option may be
          exercised within the period of one (1) year after the date the
          optionee ceases to be such an employee because of such disability (or
          within such lesser period as may be specified in the applicable option
          agreement).

For all purposes of the Plan and any option granted hereunder, "employment"
shall be defined in accordance with the provisions of Section 1.421-7(h) of the
Income Tax Regulations (or any successor regulations).  Notwithstanding the
foregoing provisions, no Incentive Stock Option may be exercised after its
expiration date.


                                       -6-


12.       ADDITIONAL PROVISIONS.

          (a)  ADDITIONAL OPTION PROVISIONS.  The Board of Directors may, in its
sole discretion, include additional provisions in option agreements covering
options granted under the Plan, including without limitation restrictions on
transfer, repurchase rights, rights of first refusal, commitments to pay cash
bonuses, to make, arrange for or guaranty loans or to transfer other property to
optionees upon exercise of options, or such other provisions as shall be
determined by the Board of Directors; PROVIDED, that such additional provisions
shall not be inconsistent with any other term or condition of the Plan and such
additional provisions shall not cause any Incentive Stock Option granted under
the Plan to fail to qualify as an Incentive Stock Option within the meaning of
Section 422 of the Code.

          (b)  ACCELERATION, EXTENSION, ETC.  The Board of Directors may, in its
sole discretion, (i) accelerate the date or dates on which all or any particular
option or options granted under the Plan may be exercised or (ii) extend the
dates during which all, or any particular, option or options granted under the
Plan may be exercised; PROVIDED, HOWEVER, that no such extension shall be
permitted if it would cause the Plan to fail to comply with Section 422 of the
Code or with Rule 16b-3 (if applicable).

13.       GENERAL RESTRICTIONS.

          (a)  INVESTMENT REPRESENTATIONS.  The Company may require any person
to whom an option is granted, as a condition of exercising such option, to give
written assurances in substance and form satisfactory to the Company to the
effect that such person is acquiring the Common Stock subject to the option, for
his or her own account for investment and not with any present intention of
selling or otherwise distributing the same, and to such other effects as the
Company deems necessary or appropriate in order to comply with federal and
applicable state securities laws, or with covenants or representations made by
the Company in connection with any public offering of its Common Stock,
including any "lock-up" or other restriction on transferability.

          (b)  COMPLIANCE WITH SECURITIES LAW.  Each option shall be subject to
the requirement that if, at any time, counsel to the Company shall determine
that the listing, registration or qualification of the shares subject to such
option upon any securities exchange or automated quotation system or under any
state or federal law, or the consent or approval of any governmental or
regulatory body, or that the disclosure of non-public information or the
satisfaction of any other condition is necessary as a condition of, or in
connection with the issuance or purchase of shares thereunder, such option may
not be exercised, in whole or in part, unless such listing, registration,
qualification, consent or approval, or satisfaction of such condition shall have
been effected or obtained on conditions acceptable to the Board of Directors.
Nothing herein shall be deemed to require the Company to apply for or to obtain
such listing, registration or qualification, or to satisfy such condition.


                                       -7-


14.       RIGHTS AS A SHAREHOLDER.

          The holder of an option shall have no rights as a shareholder with
respect to any shares covered by the option (including, without limitation, any
rights to receive dividends or non-cash distributions with respect to such
shares) until the date of issue of a stock certificate to him or her for such
shares.  No adjustment shall be made for dividends or other rights for which the
record date is prior to the date such stock certificate is issued.

15.       ADJUSTMENT PROVISIONS FOR RECAPITALIZATIONS, REORGANIZATIONS AND
          RELATED TRANSACTIONS.

          (a)  RECAPITALIZATIONS AND RELATED TRANSACTIONS.  If, through or as a
result of any recapitalization, reclassification, stock dividend, stock split,
reverse stock split or other similar transaction, (i) the outstanding shares of
Common Stock are increased, decreased or exchanged for a different number or
kind of shares or other securities of the Company, or (ii) additional shares or
new or different shares or other non-cash assets are distributed with respect to
such shares of Common Stock or other securities, an appropriate and
proportionate adjustment shall be made in (x) the maximum number and kind of
shares reserved for issuance under or otherwise referred to in the Plan, (y) the
number and kind of shares or other securities subject to any then outstanding
options under the Plan, and (z) the price for each share subject to any then
outstanding options under the Plan, without changing the aggregate purchase
price as to which such options remain exercisable.  Notwithstanding the
foregoing, no adjustment shall be made pursuant to this Section 15 if such
adjustment (i) would cause the Plan to fail to comply with Section 422 of the
Code or with Rule 16b-3 or (ii) would be considered as the adoption of a new
plan requiring stockholder approval.

          (b)  REORGANIZATION, MERGER AND RELATED TRANSACTIONS.  All outstanding
options under the Plan shall become fully exercisable for a period of sixty (60)
days following the occurrence of any Trigger Event, whether or not such options
are then exercisable under the provisions of the applicable agreements relating
thereto.  For purposes of the Plan, a "Trigger Event" is any one of the
following events:

               (i)    the date on which shares  of Common Stock are first
     purchased pursuant to a tender offer or exchange offer (other than such an
     offer by the Company, any Subsidiary, any employee benefit plan of the
     Company or of any Subsidiary or any entity holding shares or other
     securities of the Company for or pursuant to the terms of such plan),
     whether or not such offer is approved or opposed by the Company and
     regardless of the number of shares purchased pursuant to such offer;

               (ii)   the date the Company acquires knowledge that any person or
     group deemed a person under Section 13(d)-3 of the Exchange Act (other than
     the Company, any Subsidiary, any employee benefit plan of the Company or of
     any


                                       -8-


     Subsidiary or any entity holding shares  of Common Stock or other
     securities of the Company for or pursuant to the terms of any such plan or
     any individual or entity or group or affiliate thereof which acquired its
     beneficial ownership interest prior to the date the Plan was adopted by the
     Board), in a transaction or series of transactions, has become the
     beneficial owner, directly or indirectly (with beneficial ownership
     determined as provided in Rule 13d-3, or any successor rule, under the
     Exchange Act), of securities of the Company entitling the person or group
     to 30% or more of all votes (without consideration of the rights of any
     class or stock to elect directors by a separate class vote) to which all
     shareholders of the Company would be entitled in the election of the Board
     of Directors were an election held on such date;

               (iii)  the date, during any period of two consecutive years, when
     individuals who at the beginning of such period constitute the Board of
     Directors of the Company cease for any reason to constitute at least a
     majority thereof, unless the election, or the nomination for election by
     the shareholders of the Company, of each new director was approved by a
     vote of at least two-thirds of the directors then still in office who were
     directors at the beginning of such period; and

               (iv)   the date of approval by the shareholders of the Company of
     an agreement (a "reorganization agreement") providing for:

                    (A)  The merger or consolidation of the Company with another
          corporation where the shareholders of the Company, immediately prior
          to the merger or consolidation, do not beneficially own, immediately
          after the merger or consolidation, shares of the corporation issuing
          cash or securities in the merger or consolidation entitling such
          shareholders to 80% or more of all votes (without consideration of the
          rights of any class of stock to elect directors by a separate class
          vote) to which all shareholders of such corporation would be entitled
          in the election of directors or where the members of the Board of
          Directors of the Company, immediately prior to the merger or
          consolidation, do not, immediately after the merger or consolidation,
          constitute a majority of the Board of Directors of the corporation
          issuing cash or securities in the merger or consolidation; or

                    (B)  The sale or other disposition of all or substantially
          all the assets of the Company.

          (c)  BOARD AUTHORITY TO MAKE ADJUSTMENTS.  Any adjustments under this
Section 15 will be made by the Board of Directors, whose determination as to
what adjustments, if any, will be made and the extent thereof will be final,
binding and conclusive.  No fractional shares will be issued under the Plan on
account of any such adjustments.


                                       -9-


16.       MERGER, CONSOLIDATION, ASSET SALE, LIQUIDATION, ETC.

          (a)  GENERAL.  In the event of any sale, merger, transfer or
acquisition of the Company or substantially all of the assets of the Company in
which the Company is not the surviving corporation, and provided that after the
Company shall have requested the acquiring or succeeding corporation (or an
affiliate thereof), that equivalent options shall be substituted and such
successor corporation shall have refused or failed to assume all options
outstanding under the Plan or issue substantially equivalent options, then any
or all outstanding options under the Plan shall accelerate and become
exercisable in full immediately prior to such event.  The Committee will notify
holders of options under the Plan that any such options shall be fully
exercisable for a period of fifteen (15) days from the date of such notice, and
the options will terminate upon expiration of such notice.

          (b)  SUBSTITUTE OPTIONS.  The Company may grant options under the Plan
in substitution for options held by employees of another corporation who become
employees of the Company, or a subsidiary of the Company, as the result of a
merger or consolidation of the employing corporation with the Company or a
subsidiary of the Company, or as a result of the acquisition by the Company, or
one of its subsidiaries, of property or stock of the employing corporation.  The
Company may direct that substitute options be granted on such terms and
conditions as the Board of Directors considers appropriate in the circumstances.

17.       NO SPECIAL EMPLOYMENT RIGHTS.

          Nothing contained in the Plan or in any option shall confer upon any
optionee any right with respect to the continuation of his or her employment by
the Company or interfere in any way with the right of the Company at any time to
terminate such employment or to increase or decrease the compensation of the
optionee.

18.       OTHER EMPLOYEE BENEFITS.

          Except as to plans which by their terms include such amounts as
compensation, the amount of any compensation deemed to be received by an
employee as a result of the exercise of an option or the sale of shares received
upon such exercise will not constitute compensation with respect to which any
other employee benefits of such employee are determined, including, without
limitation, benefits under any bonus, pension, profit-sharing, life insurance or
salary continuation plan, except as otherwise specifically determined by the
Board of Directors.

19.       AMENDMENT OF THE PLAN.

          (a)  The Board of Directors may at any time, and from time to time,
modify or amend the Plan in any respect; provided, however, that if at any time
the approval of the shareholders of the Company is required under Section 422 of
the Code or any


                                      -10-


successor provision with respect to Incentive Stock Options, or under
Rule 16b-3, the Board of Directors may not effect such modification or amendment
without such approval; and provided, further, that the provisions of
Section 3(c) hereof shall not be amended more than once every six months, other
than to comport with changes in the Code, the Employer Retirement Income
Security Act of 1974, as amended, or the rules thereunder.

          (b)  The modification or amendment of the Plan shall not, without the
consent of an optionee, affect his or her rights under an option previously
granted to him or her.  With the consent of the optionee affected, the Board of
Directors may amend outstanding option agreements in a manner not inconsistent
with the Plan.  The Board of Directors shall have the right to amend or modify
(i) the terms and provisions of the Plan and of any outstanding Incentive Stock
Options granted under the Plan to the extent necessary to qualify any or all
such options for such favorable federal income tax treatment (including deferral
of taxation upon exercise) as may be afforded incentive stock options under
Section 422 of the Code and (ii) the terms and provisions of the Plan and of any
outstanding option to the extent necessary to ensure the qualification of the
Plan under Rule 16b-3.

20.       WITHHOLDING.

          (a)  The Company shall have the right to deduct from payments of any
kind otherwise due to the optionee any federal, state or local taxes of any kind
required by law to be withheld with respect to any shares issued upon exercise
of options under the Plan.  Subject to the prior approval of the Company, which
may be withheld by the Company in its sole discretion, the optionee may elect to
satisfy such obligations, in whole or in part, (i) by causing the Company to
withhold shares of Common Stock otherwise issuable pursuant to the exercise of
an option or (ii) by delivering to the Company shares of Common Stock already
owned by the optionee.  The shares so delivered or withheld shall have a Fair
Market Value equal to such withholding obligation as of the date that the amount
of tax to be withheld is to be determined.  An optionee who has made an election
pursuant to this Section 20(a) may only satisfy his or her withholding
obligation with shares of Common Stock which are not subject to any repurchase,
forfeiture, unfulfilled vesting or other similar requirements.

          (b)  The acceptance of shares of Common Stock upon exercise of an
Incentive Stock Option shall constitute an agreement by the optionee (i) to
notify the Company if any or all of such shares are disposed of by the optionee
within two years from the date the option was granted or within one year from
the date the shares were issued to the optionee pursuant to the exercise of the
option, and (ii) if required by law, to remit to the Company, at the time of and
in the case of any such disposition, an amount sufficient to satisfy the
Company's federal, state and local withholding tax obligations with respect to
such disposition, whether or not, as to both (i) and (ii), the optionee is in
the employ of the Company at the time of such disposition.


                                      -11-


          (c)  Notwithstanding the foregoing, in the case of a Reporting Person
whose options have been granted in accordance with the provisions of
Section 3(b) herein, no election to use shares for the payment of withholding
taxes shall be effective unless made in compliance with any applicable
requirements of Rule 16b-3.

21.       CANCELLATION AND NEW GRANT OF OPTIONS, ETC.

          The Board of Directors shall have the authority to effect, at any time
and from time to time, with the consent of the affected optionees, (i) the
cancellation of any or all outstanding options under the Plan and the grant in
substitution therefor of new options under the Plan covering the same or
different numbers of shares of Common Stock and having an option exercise price
per share which may be lower or higher than the exercise price per share of the
cancelled options or (ii) the amendment of the terms of any and all outstanding
options under the Plan to provide an option exercise price per share which is
higher or lower than the then-current exercise price per share of such
outstanding options.

22.       EFFECTIVE DATE AND DURATION OF THE PLAN.

          (a)  EFFECTIVE DATE.  The Plan shall become effective when adopted by
the Board of Directors, but no Incentive Stock Option granted under the Plan
shall become exercisable unless and until the Plan shall have been approved by
the Company's shareholders.  If such shareholder approval is not obtained within
twelve months after the date of the Board's adoption of the Plan, no options
previously granted under the Plan shall be deemed to be Incentive Stock Options
and no Incentive Stock Options shall be granted thereafter.  Amendments to the
Plan not requiring shareholder approval shall become effective when adopted by
the Board of Directors; amendments requiring shareholder approval (as provided
in Section 21) shall become effective when adopted by the Board of Directors,
but no Incentive Stock Option granted after the date of such amendment shall
become exercisable (to the extent that such amendment to the Plan was required
to enable the Company to grant such Incentive Stock Option to a particular
optionee) unless and until such amendment shall have been approved by the
Company's shareholders.  If such shareholder approval is not obtained within
twelve months of the Board's adoption of such amendment, any Incentive Stock
Options granted on or after the date of such amendment shall terminate to the
extent that such amendment to the Plan was required to enable the Company to
grant such option to a particular optionee.  Subject to this limitation, options
may be granted under the Plan at any time after the effective date and before
the date fixed for termination of the Plan.

          (b)  TERMINATION.  Unless sooner terminated in accordance with
Section 16, the Plan shall terminate upon the earlier of (i) the close of
business on the day next preceding the tenth anniversary of the date of its
adoption by the Board of Directors, or (ii) the date on which all shares
available for issuance under the Plan shall have been issued pursuant to the
exercise or cancellation of options granted under the Plan.  If the date of
termination is


                                      -12-


determined under (i) above, then options outstanding on such date shall continue
to have force and effect in accordance with the provisions of the instruments
evidencing such options.

23.       PROVISION FOR FOREIGN PARTICIPANTS.

          The Board of Directors may, without amending the Plan, modify awards
or options granted to participants who are foreign nationals or employed outside
the United States to recognize differences in laws, rules, regulations or
customs of such foreign jurisdictions with respect to tax, securities, currency,
employee benefit or other matters.

24.       GOVERNING LAW.

          The provisions of this Plan shall be governed and construed in
accordance with the laws of the State of New York without regard to the
principles of conflicts of laws.

                    Adopted by the Board of Directors on November 8, 1994
