                                   SECTION 4

accordance with the provisions of the Plan.

                                   SECTION 5

         (a) SHARES AVAILABLE FOR AWARDS.  Subject to adjustment as provided 
in Section 5(b):

                                     -3-



              (i)  CALCULATION OF NUMBER OF SHARES AVAILABLE.   The number of 
    Shares with respect to which Awards may be granted under the Plan shall 
    be such number of Shares as results from the application of the award 
    formulas set forth in Sections 6 and 7.  If, after the effective date of 
    the Plan, an Award granted under the Plan expires or is exercised, 
    forfeited, canceled or terminated without the delivery of Shares, then 
    the Shares covered by such Award or to which such Award relates, or the 
    number of Shares otherwise counted against the aggregate number of 
    Shares with respect to which Awards may be granted, to the extent of any 
    such expiration, exercise, forfeiture, cancellation or termination, 
    shall not thereafter be available for grants or Awards under the Plan.

              (ii)  SOURCES OF SHARES DELIVERABLE UNDER AWARDS.  Any Shares
    delivered pursuant to an Award may consist of authorized and unissued Shares
    or of treasury Shares, including Shares held by the Company or a Subsidiary 
    and acquired in the open market or otherwise obtained by the Company or a
    Subsidiary.

              (iii)  INDIVIDUAL LIMIT.  Any provision of the Plan to the 
    contrary notwithstanding, no individual may receive in any year Awards under
    the Plan, whether payable in cash or Shares, that relate to more than 
    200,000 Shares.

         (b) ADJUSTMENTS.  In the event that the Committee determines that 
any dividend or other distribution (whether in the form of cash, Shares, 
Subsidiary securities, other securities or other property), recapitalization, 
stock split, reverse stock split, reorganization, merger, consolidation, 
split-up, spin-off, combination, repurchase or exchange of Shares or other 
securities of the Company, issuance of warrants or other rights to purchase 
Shares or other securities of the Company, or other similar corporate 
transaction or event affects the Shares such that an adjustment is determined 
by the Committee to be appropriate to prevent dilution or enlargement of the 
benefits or potential benefits intended to be made available under the Plan, 
then the Committee may, in its sole discretion and in such manner as it may 
deem equitable, adjust any or all of (i) the number and type of Shares (or 
other securities or property) with respect to which Awards may be granted, 
(ii) the number and type of Shares (or other securities or property) subject 
to outstanding Awards, and (iii) the grant or exercise price with respect to 
any Award or, if deemed appropriate, make provision for a cash payment to the 
holder of an outstanding Award; PROVIDED, that the number of Shares subject 
to any Award denominated in Shares shall always be a whole number.

                                 SECTION 6

         (a) STOCK OPTIONS.  Immediately prior to the Distribution, each 
holder of an FTX Award shall receive an Option to purchase such number of 
Shares (disregarding any fractional Share) as such holder would be eligible 
to receive in the Distribution with respect to the number of shares of FTX 
common stock subject to such FTX Award if such holder were the owner of 
record of such FTX shares on the record date for the Distribution.  Except as 
set forth in Sections 6(b) and 6(c), each such Option shall have the same 
remaining term and other terms and conditions (whether such terms and 
conditions are contained in the related FTX Award agreement or in the plan 
under which such FTX Award was made) and shall be immediately exercisable in 
full, as were the FTX 

                                     -4-



Awards from which they were derived as a result of the change of control of 
FTX, with such changes and modifications as are necessary to substitute the 
Company for FTX as the issuer of the Option.

         (b) EXERCISE PRICE.  The per Share exercise price of each Option 
granted pursuant to Section 6(a) shall be the per share exercise price or 
grant price of the FTX Award from which such Option was derived multiplied by 
a fraction, the numerator of which is the "Company Distribution Value," as 
defined below, and the denominator of which is the "FTX Distribution Value," 
as defined below.  For purposes of this Section 6(b), the "Company 
Distribution Value" shall be the weighted average per Share price of the 
Shares on the New York Stock Exchange on the first day that Shares are traded 
on the New York Stock Exchange after the effective date of the Merger, and 
the FTX Distribution Value shall be the weighted average per share price of 
the FTX common stock on the New York Stock Exchange on the last day that 
shares of FTX common stock are traded on the New York Stock Exchange before 
the effective date of the Merger.

         (c) TAX-OFFSET RIGHT ADJUSTMENT.  Notwithstanding the foregoing, if 
the FTX Option from which the Option granted under this Section 6 derives 
contained a right to receive a cash payment upon exercise of such FTX Option 
related to and intended to defray the income tax liability associated 
therewith, the number of Shares to be subject to the Option, determined 
according to the provisions of Section 6(a) (without disregarding fractional 
Shares), shall be multiplied by 1.6556 and any fractional Share resulting 
from such adjustment shall be disregarded.  Such adjustment shall not affect 
the calculation of the per Share exercise price of the Option as set forth in 
Section 6(b).

         (d) PAYMENT.  No Shares shall be delivered pursuant to any exercise 
of an Option until payment in full of the option price therefor is received 
by the Company. Such payment may be made in cash, or its equivalent, or, if 
and to the extent permitted by the Committee, by applying cash amounts 
payable by the Company upon the exercise of such Option or other Awards by 
the holder thereof or by exchanging whole Shares owned by such holder (which 
are not the subject of any pledge or other security interest), or by a 
combination of the foregoing, provided that the combined value of all cash, 
cash equivalents, cash amounts so payable by the Company upon exercises of 
Awards and the fair market value of any such whole Shares so tendered to the 
Company, valued (in accordance with procedures established by the Committee) 
as of the effective date of such exercise, is at least equal to such option 
price.

                                 SECTION 7

         (a) LIMITED RIGHTS.  Each holder of an FTX Award shall receive, at 
the same time as and in tandem with each Option granted to such holder under 
Section 6, Limited Rights equal in number to the number of Shares subject to 
such Option with which such Limited Rights are in tandem.  Such Limited 
Rights shall have a grant price equal to the exercise price of the Option 
under Section 6 with which it is in tandem, and shall in all other respects 
contain the same terms and conditions as the agreement pertaining to the FTX 
Award from which they derived.

         (b) A Limited Right shall entitle the holder thereof to receive an 
amount equal to the excess, if any, of the Offer Price on the date of 
exercise of the Limited Right over the grant price.  

                                     -5-



Any Limited Right may be settled in cash, Shares or a combination of cash and 
Shares, as determined by the Committee or the Board at the time of exercise, 
and shall only be exercisable during a period beginning not earlier than one 
day and ending not more than ninety days after the expiration date of an 
Offer.

                                  SECTION 8

         (a) AMENDMENTS TO THE PLAN.  The Board may amend, suspend or 
terminate the Plan or any portion thereof at any time, provided that no 
amendment shall be made without stockholder approval if such approval is 
necessary to comply with any tax or regulatory requirement, including for 
these purposes any approval necessary to qualify Awards as "performance 
based" compensation under Section 162(m) or any successor provision if such 
qualification is deemed necessary or desirable by the Committee.   
Notwithstanding anything to the contrary contained herein, (i) the Committee 
may amend the Plan in such manner as may be necessary for the Plan to conform 
with local rules and regulations in any jurisdiction outside the United 
States and (ii) any amendment, suspension or termination made in accordance 
with this Section 8(a) that would adversely affect a holder's rights under an 
Award made under the Plan may not be made without such holder's consent.

         (b) AMENDMENTS TO AWARDS.  The Committee may amend, modify or 
terminate any outstanding Award with the holder's consent at any time prior 
to payment or exercise in any manner not inconsistent with the terms of the 
Plan, including without limitation, a change in the date or dates as of which 
an Award becomes exercisable.

         (c) ADJUSTMENT OF AWARDS UPON THE OCCURRENCE OF CERTAIN UNUSUAL OR 
NONRECURRING EVENTS.  The Committee is hereby authorized to make adjustments 
in the terms and conditions of, and the criteria included in, Awards in 
recognition of unusual or nonrecurring events (including, without limitation, 
the events described in Section 5(b) hereof) affecting the Company, or the 
financial statements of the Company or any Subsidiary, or of changes in 
applicable laws, regulations, or accounting principles, whenever the 
Committee determines that such adjustments are appropriate to prevent 
dilution or enlargement of the benefits or potential benefits intended to be 
made available under the Plan.

         (d) CANCELLATION.  Any provision of this Plan or any Award Agreement 
to the contrary notwithstanding, the Committee may cause any Award granted 
hereunder to be canceled in consideration of a cash payment or alternative 
Award made to the holder of such canceled Award equal in value to such 
canceled Award.  The determinations of value under this subsection shall be 
made by the Committee in its sole discretion.

                                 SECTION 9

         (a) AWARD AGREEMENTS.  Each Award hereunder shall be evidenced by a 
writing delivered to the Participant that shall specify the terms and 
conditions thereof and any rules applicable thereto and that shall, in 
accordance with the provisions of the Plan, replicate as closely 

                                     -6-



as possible the terms, conditions and other contractual attributes of the FTX 
Award from which the Award is derived, as in effect on the Distribution Date.

         (b) WITHHOLDING.   (i)  A Participant may be required to pay to the 
Company, and the Company shall have the right to deduct from all amounts paid 
to a Participant (whether under the Plan or otherwise), any taxes required by 
law to be paid or withheld in respect of Awards hereunder to such 
Participant. 

              (ii)  At any time that a Participant is required to pay to the 
Company an amount required to be withheld under the applicable tax laws in 
connection with the issuance of Shares under the Plan, the Participant may, 
if permitted by the Committee, satisfy this obligation in whole or in part by 
electing (the "Election") that the Company withhold from the issuance Shares 
having a value equal to the amount required to be withheld.  The value of the 
Shares withheld shall be based on the fair market value of the Shares on the 
date that the amount of tax to be withheld shall be determined in accordance 
with applicable tax laws (the "Tax Date").

              (iii)  Each Election must be made prior to the Tax Date.  The 
Committee may suspend or terminate the right to make Elections at any time.

              (iv)  A Participant may also satisfy his total tax liability 
related to the Award by delivering Shares owned by the Participant.  The 
value of the Shares delivered shall be based on the fair market value of the 
Shares on the Tax Date. 

         (c) TRANSFERABILITY.  No Awards granted hereunder may be 
transferred, pledged, assigned or otherwise encumbered by a Participant 
except: (i) by will; (ii) by the laws of descent and distribution; (iii) 
pursuant to a domestic relations order, as defined in the Code, if permitted 
by the Committee and so provided in the Award Agreement or an amendment 
thereto; or (iv) if permitted by the Committee and so provided in the Award 
Agreement or an amendment thereto, (a) to Immediate Family Members, (b) to a 
partnership in which Immediate Family Members, or entities in which Immediate 
Family Members are the owners, members or beneficiaries, as appropriate, are 
the partners, (c) to a limited liability company in which Immediate Family 
Members, or entities in which Immediate Family Members are the owners, 
members or beneficiaries, as appropriate, are the members, or (d) to a trust 
for the benefit of Immediate Family Members; provided, however, that no more 
than a DE MINIMUS beneficial interest in a partnership, limited liability 
company or trust described in (b), (c) or (d) above may be owned by a person 
who is not an Immediate Family Member or by an entity that is not 
beneficially owned solely by Immediate Family Members. "Immediate Family 
Members" shall be defined as the spouse and natural or adopted children or 
grandchildren of the Participant and their spouses.  Any attempted 
assignment, transfer, pledge, hypothecation or other disposition of Awards, 
or levy of attachment or similar process upon Awards not specifically 
permitted herein, shall be null and void and without effect.  The designation 
of a Designated Beneficiary shall not be a violation of this Section 9(c).

         (d) SHARE CERTIFICATES.  All certificates for Shares or other 
securities delivered under the Plan pursuant to any Award or the exercise 
thereof shall be subject to such stop transfer orders and other restrictions 
as the Committee may deem advisable under the Plan or the rules, regulations, 

                                     -7-



and other requirements of the SEC, any stock exchange upon which such Shares 
or other securities are then listed, and any applicable federal or state 
laws, and the Committee may cause a legend or legends to be put on any such 
certificates to make appropriate reference to such restrictions.

         (e) NO LIMIT ON OTHER COMPENSATION ARRANGEMENTS.   Nothing contained 
in the Plan shall prevent the Company from adopting or continuing in effect 
other compensation arrangements, which may, but need not, provide for the 
grant of options and other types of Awards provided for hereunder (subject to 
stockholder approval of any such arrangement if approval is required), and 
such arrangements may be either generally applicable or applicable only in 
specific cases.

         (f) NO RIGHT TO EMPLOYMENT.  The grant of an Award shall not be 
construed as giving a Participant the right to be engaged or employed by or 
retained in the employ of FTX, the Company or any Subsidiary.  FTX, the 
Company or any Subsidiary may at any time dismiss a Participant from 
engagement or employment, free from any liability or any claim under the 
Plan, unless otherwise expressly provided in the Plan or in any Award 
Agreement or any agreement relating to the engagement or employment of the 
Participant by FTX, the Company or any Subsidiary.

         (g) GOVERNING LAW.  The validity, construction, and effect of the 
Plan, any rules and regulations relating to the Plan and any Award Agreement 
shall be determined in accordance with the laws of the State of Delaware.

         (h) SEVERABILITY.  If any provision of the Plan or any Award is or 
becomes or is deemed to be invalid, illegal, or unenforceable in any 
jurisdiction or as to any Person or Award, or would disqualify the Plan or 
any Award under any law deemed applicable by the Committee, such provision 
shall be construed or deemed amended to conform to applicable laws, or if it 
cannot be construed or deemed amended without, in the determination of the 
Committee, materially altering the intent of the Plan or the Award, such 
provision shall be stricken as to such jurisdiction, Person or Award and the 
remainder of the Plan and any such Award shall remain in full force and 
effect.

         (i) NO TRUST OR FUND CREATED.  Neither the Plan nor any Award shall 
create or be construed to create a trust or separate fund of any kind or a 
fiduciary relationship between the Company and a Participant or any other 
Person.  To the extent that any Person acquires a right to receive payments 
from the Company pursuant to an Award, such right shall be no greater than 
the right of any unsecured general creditor of the Company.

         (j) NO FRACTIONAL SHARES.  No fractional Shares shall be issued or 
delivered pursuant to the Plan or any Award, and the Committee shall 
determine, in accordance with the terms of the Plan, as applicable, whether 
cash, other securities or other property shall be paid or transferred in lieu 
of any fractional Shares or whether such fractional Shares or any rights 
thereto shall be canceled, terminated, or otherwise eliminated.

         (k) HEADINGS.  Headings are given to the subsections of the Plan 
solely as a convenience to facilitate reference.  Such headings shall not be 
deemed in any way material or relevant to the construction or interpretation 
of the Plan or any provision thereof.

                                     -8-



                                   SECTION 10

         EFFECTIVE DATE OF THE PLAN.  The Plan shall be effective as of the 
date of its approval by the stockholder of the Company.

                                   SECTION 11

         TERM OF THE PLAN.  Subject to Section 5(b), no Award shall be 
granted under the Plan except the Awards provided for in Sections 6 and 7.  
Awards granted hereunder shall continue until their respective expiration 
dates, and the authority of the Committee to administer, interpret, amend, 
alter, adjust, suspend, discontinue, or terminate, in accordance with the 
provisions of the Plan, any such Award or to waive any conditions or rights 
under any such Award shall extend until the latest such date.



                                     -9-
