                                    PURPOSE

      The purpose of this Employee Stock Purchase Plan is to provide a greater
community of interest between RTW, Inc. shareholders and its employees, and to
facilitate purchase by employees of additional shares of stock in the Company.
It is believed the Plan will encourage employees to remain in the employ of the
Company and will also permit the Company to compete with other corporations
offering similar plans in obtaining and retaining the services of competent
employees.  It is intended that options issued pursuant to this Plan shall
constitute options issued pursuant to an "Employee Stock Purchase Plan" within
the meaning of Section 423 of the Internal Revenue Code of 1986, as amended.

                                   SECTION 2

      (b) "Code" means the Internal Revenue Code of 1986, as amended.

      (c) "Company" means RTW, Inc., and any of its subsidiaries (as that term
is defined by Section 425(f) of the Code) to which RTW, Inc. and such respective
subsidiaries by action of their Boards of Directors shall make this Plan
applicable.

      (d) "Employee" means any person, including an officer, who is customarily

for participation in the Plan in accordance with Section 4.

      (f) "Participant" means an Eligible Employee who has elected to
participate in the Plan in accordance with Section 5.

      (g) "Committee" means the committee provided for in Section 11.

      (h) The "Commencement Date" of the Plan means the date the Company's

special remuneration.

      (j) "Termination Date" with respect to any Phase shall mean (i) the date
designated by the Company's Board of Directors for a Phase to end, or (ii) the

                                   SECTION 3

                          TERM AND PHASES OF THE PLAN

      (a) The Plan will commence on the Commencement Date and will terminate ten

increase in the number of shares issuable under the Plan. Foregoing, this Plan

after the termination of the preceding Phase. The commencement of each Phase
shall be determined by the Committee, provided that the commencement of the
first Phase shall be within twelve (12) months before or after the date of
approval of the Plan by the shareholders of the Company. In the event all of the
stock reserved for grant of options hereunder is issued pursuant to the terms
hereof prior to the commencement of one or more Phases scheduled by the

      shares possessing five percent (5%) or more of the total combined voting
      power or value of all classes of shares of the Company or a parent or a
      subsidiary of the Company. For purposes of determining share ownership,
      the rules of Section 425(d) of the Code shall apply, and shares which the
      Employee may purchase under outstanding options shall be treated as shares
      owned by the Employee; or

            2. Which permits the Employee to purchase shares under such plans of
      the Company or a parent or a subsidiary of the Company to accrue at a rate
      which exceeds $25,000 of the fair market value-of such shares (determined
      at the time such option is granted) for each calendar year in which such
      option is outstanding at any time.

Phase, subject to the limitations of Section 10. The maximum number of shares

      (e) The fair market value of the shares shall be determined by the
Committee for each valuation date in a manner consistent with Section 423 of
the Code.

                               EXERCISE OF OPTION

      (a) Unless a Participant gives written notice to the Company as provided
in Section 9, an option for the purchase of shares will be exercised
automatically as of the Termination Date of the Phase for the purchase of the
number of full shares which the accumulated payroll deductions in the
Participant's account at that time will purchase at the applicable option price,
but in no event shall the number of full shares be greater than the number of
full shares which the Participant is eligible to purchase under Section 7,
paragraph (b).

      (b) By written notice to the Company within one week prior to the
Termination Date of the Phase a Participant may elect, effective at the
Termination Date, to:

            1. withdraw all the accumulated payroll deductions in the
      Participant's account at the time, without interest;

            2. exercise his option for a specified number of full shares less

      his account will purchase at the applicable option price, and withdraw the
      balance in the Participant's account without interest, but in no event
      shall the number of full shares be greater than the number of full shares
      to which a Participant is eligible to purchase under Section 7, paragraph
      (b).

                                   SECTION 9

Company within sixty (60) days of the death of the Participant, but in no event
later than the end of the period specified in Section 8, paragraph (b), electing
to purchase the number of full shares which the accumulated payroll deductions
in the account of such deceased Participant will purchase at the option price
specified in paragraph (c) of Section 7 and have the balance in the account

the Plan for any reason other than the death of the Participant, the payroll
deductions credited to his account without interest shall be returned to such
Participant promptly.

      (c) A Participant may withdraw all or any part of the payroll deductions
credited to his account under the Plan at any time by giving written notice to

the number of shares then available under the Plan (after deduction of all
shares for which options have been exercised or are then outstanding), the
Committee shall make a pro rata allocation of the shares remaining available in
as nearly a uniform manner as shall be practicable and as it shall determine to
be equitable. In such event, payroll deductions to be made shall be reduced
accordingly and the Committee shall give written notice of such reduction to
each Participant affected thereby.

      (b) As promptly as practicable after the Termination Date of a Phase, the
Company shall deliver to each Participant the full shares purchased under

who shall be appointed by the Board of Directors of the Company. Each member of
such Committee shall be either a director, an officer or an employee of the
Company. Unless the Board of Directors limits the authority delegated to the
Committee in its appointment, the Committee shall be vested with full authority
to make, administer, and interpret such rules and regulations as it deems
necessary to administer the Plan, and any such determination, decision or action
of such Committee with respect to any action in connection with the
construction, interpretation administration or application of the Plan shall be
final, conclusive and binding on all Participants and any and all other persons
claiming under or through any Participant. It is provided, however, that the
provisions of the Plan shall be construed so as to extend and limit

                               NONTRANSFERABILITY

      Neither payroll deductions credited to a Participant's account nor any
rights with regard to the exercise of an option or to receive shares under the
Plan may be assigned, transferred, pledged or otherwise disposed of in any way
by the Participant and any such attempted assignment, transfer, pledge or other
disposition shall be null and void and without effect, but the Company may treat
such act as an election to withdraw funds in accordance with Section 9.

                                   SECTION 14

                                  USE OF FUNDS

                    CHANGES IN CAPITALIZATION, MERGER, ETC.

      (a) Subject to any required action by the shareholders, the number of
shares covered by each outstanding option, and the price per share thereof in
each such option, shall be proportionately adjusted for any increase or decrease
in the number of issued shares of the Company resulting from a subdivision or
consolidation of shares or the payment of a share dividend (but only on the
shares) or any other increase or decrease in the number of such shares effected
without receipt of consideration by the Company.

      (b) Subject to any required action by the shareholders, if the Company
shall be involved in any merger or consolidation, in which it is the surviving
corporation, each outstanding option shall pertain to and apply to the
securities to which a holder of the number of shares subject to the option would
have been entitled. A dissolution or liquidation of the Company shall cause each
outstanding option to terminate, provided in such event that, immediately prior
to such dissolution or liquidation, each Participant shall be repaid the payroll
deductions credited to his account without interest.

      (c) In the event of a change in the shares of the Company as presently
constituted, which is limited to a change of all its authorized shares with par
value into the same number of shares with a different par value or without par

                             ADJUSTMENTS TO SHARES

      (a) To the extent that the foregoing adjustments relate to shares or
securities of the Company, such adjustments shall be made by the Committee, and
its determination in that respect shall be final, binding and conclusive,
provided that each option granted pursuant to this Plan shall not be adjusted in
a manner that causes the option to fail to continue to qualify as an option
issued pursuant to an "employee stock purchase plan" within the meaning of
Section 423 of the Code.

      (b) Except as hereinbefore expressly provided in Sections 16 and 17, the
optionee shall have no right by reason of any subdivision or consolidation of
shares of any class or the payment of any stock dividend or any other increase
or decrease in the number of shares of any class or by reason of any
dissolution, liquidation, merger, or consolidation or spin-off of assets or
stock of another corporation, and any issue by the Company of shares of any
class, or securities convertible into shares of any class, shall not affect, and
no adjustment by reason thereof shall be made with respect to, the number or
price of shares subject to the option.

way the right or power of the Company to make adjustments, reclassifications,
reorganizations or changes of its capital or business structure or to merge or
to consolidate or to dissolve, liquidate or sell, or transfer all or any part of
its business or assets.

                                   SECTION 18

                            BENEFICIARY DESIGNATION

      A Participant may file a written designation of a beneficiary who may
elect to purchase shares or receive cash to the Participant's credit under the
Plan in the event of such Participant's death prior to delivery to him of such
shares and cash. Such designation of beneficiary may be changed by the
Participant at any time by written notice delivered to the Company. Upon the
death of a Participant and upon receipt by the Company of proof deemed adequate
by it of the identity and existence at the Participant's death of a beneficiary
validly designated by him under the Plan, the Company shall deliver such shares
and cash to such beneficiary in accordance with paragraph (a) of Section 9. If
upon the death of a Participant there is no surviving beneficiary duly
designated as above provided, the Company shall deliver accumulated payroll
deductions to the executor or administrator of the estate of the Participant, or
if no such executor or administrator has been appointed (to the knowledge of
the Company) within sixty (60) days following the Participant's death, the
Company shall deliver such accumulated payroll deductions to the surviving
spouse, if any, as though named as the designated beneficiary hereunder, or if
there is no such surviving spouse or child, then to such relatives of the
Participant as would be entitled to such amounts, under the laws of intestacy in
the deceased Participant's domicile as though named as the designated
beneficiary hereunder. The Company shall not be liable for any distribution made
of shares or cash pursuant to any will or other testamentary disposition made by
such Participant, or because of the provisions of law concerning intestacy, or
otherwise. No designated beneficiary shall, prior to the death of the
Participant by whom he has been designated, acquire any interest in the shares
or cash credited to the Participant under the Plan.

                                   SECTION 19

                    REGISTRATION AND QUALIFICATION OF SHARES

      The offering of the shares hereunder shall be subject to the effecting by
the Company of any registration or qualification of the shares under any federal
or state law or the obtaining of the consent or approval of any governmental
regulatory body which the Company shall determine, in its sole discretion, is
necessary or desirable as a condition to or in connection with, the offering or
the issue or purchase of the shares covered thereby. The Company shall make
every reasonable effort to effect such registration or qualification or to
obtain such consent or approval.

                                   SECTION 20

                               PLAN PRECONDITIONS

      The Plan is expressly made subject to (i) the approval by shareholders of
the Company, and (ii) at its election, the receipt by the Company from the
Internal Revenue Service of a determination letter or ruling, in scope and
content satisfactory to counsel, respecting the qualification of the Plan within
the meaning of Section 423 of the Code. If the Plan is not so approved by the
shareholders and if, at the election of the Company, the aforesaid determination
letter or ruling from the Internal Revenue Service is not received on or before
one year after this Plan's adoption by the Board of Directors, this Plan shall
not come into effect. In such case, the accumulated payroll deductions credited
to the account of each Participant shall forthwith be repaid to him without
interest.
