2.  STOCK SUBJECT TO THE PLAN

     Subject to the provisions of Section 9 hereof (relating to adjustments upon
changes in the Stock) and Section 11 hereof (relating to amendments of the
Plan), the Stock which may be sold pursuant to Options granted under the Plan
shall not exceed in the aggregate 100,000 shares, and may be unissued shares or
treasury shares or shares bought on the market for purposes of the Plan.

3.  GRANT OF OPTIONS

     (a) General Statement. The Company shall offer Options under the Plan to
all Eligible Employees in successive six-month Offering Periods commencing on
July 1, 1993 and continuing until the earlier of (i) the date when the number of
shares of Stock available under the Plan have been sold or (ii) the date when
the Plan is terminated. Dates of Grant shall include January 1 and July 1 of
each Plan Year and such other date or dates as the Committee may from time to
time determine.  Each Option shall expire on the Date of Exercise immediately
after the automatic exercise of the Option pursuant to Section 4(a) hereof.  The
number of shares of Stock subject to each Option shall equal the payroll
deductions authorized by each Participant in accordance with subsection (b)
hereof for the Option Period, divided by the Option Price, except as provided in
Section 4(a).

                                       2

 
     (b) Election to Participate; Payroll Deduction Authorization. Except as
provided in subsection (d) hereof, an Eligible Employee shall participate in the
Plan only by means of payroll deduction.  Each Eligible Employee who elects to
participate in the Plan shall deliver to the Company during the calendar month
preceding a Date of Grant no later than five (5) working days before such Date
of Grant, a completed and executed written payroll deduction authorization in a
form prepared by the Company (the "Authorization"). An Eligible Employee's
Authorization shall give notice of such Eligible Employee's election to
participate in the Plan for the next following Offering Period and subsequent
Offering Periods and shall designate a stated whole percentage of Eligible
Compensation to be withheld on each Payday. The amount withheld shall not be
less than $10.00 each Payday and the stated percentage shall not exceed 10% of
Eligible Compensation. The cash compensation payable to a Participant for an
Offering Period shall be reduced each Payday through a payroll deduction in an
amount equal to the stated percentage of Eligible Compensation specified in the
Authorization payable on such Payday, and such amount shall be credited to the
Participant's account under the Plan. Any Authorization shall remain in effect
until the Eligible Employee amends the same pursuant to this subsection,
withdraws pursuant to Section 5 or ceases to be an Eligible Employee pursuant to
Section 6.

     (c) $25,000 Limitation. No Eligible Employee shall be granted an Option
under the Plan which permits his rights to purchase stock under the Plan and
under all other employee stock purchase plans of the Company, any Parent
Corporation or any Subsidiary Corporation subject to the Section 423 to accrue
at a rate which exceeds $25,000 of fair market value of such stock (determined
at the time the Option is granted) for each calendar year in which the Option is
outstanding at any time.  For purpose of the limitation imposed by this
subsection, the right to purchase stock under an Option accrues when the Option
(or any portion thereof) first becomes exercisable during the calendar year, the
right to purchase stock under an Option accrues at the rate provided in the
Option, but in no case may such rate exceed $25,000 of the fair market value of
such stock (determined at the time such Option is granted) for any one calendar
year, and a right to purchase stock which has accrued under an Option may not be
carried over to any other Option.

     (d) Leaves of Absence. During a leave of absence meeting the requirements
of Treasury Regulation Section 1.421-7(h)(2), a Participant may continue to
participate in the Plan by making cash payments to the Company on each Payday
equal to the amount of the Participant's payroll deductions under the Plan for
the Payday immediately preceding the first day of such Participant's leave of
absence.

4.  EXERCISE OF OPTIONS; OPTION PRICE

     (a) General Statement.  Each Participant automatically and without any act
on such Participant's part shall be deemed to have exercised such Participant's
Option on the Date of Exercise to the extent that the balance then in the
Participant's account under the Plan is sufficient to purchase at the Option
Price whole shares of the Stock subject to the Option.  No fractional shares of
Stock shall be purchased upon the exercise of an Option and any excess balance
in a Participant's account remaining after the purchase of whole shares of Stock
upon the exercise of an Option shall be paid to the Participant by the Company
in cash in one lump sum within sixty (60) days after the Date of Exercise,
without any interest thereon.

     (b) Option Price Defined. The option price per share of Stock (the "Option
Price") to be paid by a Participant upon the exercise of the Participant's
Option shall be equal to 85% of the lesser of the fair market value of a share
of Stock on the Date of Exercise or the fair market value of a share of Stock on
the Date of Grant.  The fair market value of a share of Stock as of a given date
shall be: (i) the average of the closing prices of a share of Stock on the
principal exchange on which the Stock is then trading, if any, on the three
trading days immediately preceding such date; (ii) if the Stock is not traded on
an exchange but is quoted on NASDAQ or a successor quotation system, (1) the
average of the last sales price (if the Stock is then listed as a National
Market Issue under the NASD National Market System) or (2) the average of the
mean between the closing representative bid and asked prices (in all other
cases) for a share of the Stock for the three trading days immediately preceding
such date as reported by NASDAQ or such successor quotation system; (iii) if the
Stock is not publicly traded on an exchange and not quoted on NASDAQ or a
successor quotation system, the average of the mean between the closing bid and
asked prices for a share of Stock for the three trading days immediately
preceding such date as determined in good faith by the Committee; or (iv) if the
Stock is not publicly traded, the fair market value of a share of Stock

                                       3

 
established by the Committee acting in good faith.

     (c) Delivery of Share Certificates. As soon as practicable after each Date
of Exercise, the Company shall deliver to each Participant a certificate issued
in the Participant's name for the number of shares of Stock with respect to
which the Participant's Option was exercised.  In the event the Company is
required to obtain authority from any commission or agency to issue any such
certificate, the Company shall seek to obtain such authority.  The inability of
the Company to obtain authority from any such commission or agency which the
Committee in its absolute discretion, deems necessary for the lawful issuance of
any such certificate shall relieve the Company from liability to any Participant
except to pay to the Participant the amount of the balance in the Participant's
account in cash in one lump sum without any interest thereon.

     (d) Pro Rata Allocations. If the total number of shares of Stock for which
Options are to be exercised on any date exceeds the number of shares remaining
unsold under the Plan (after deduction of all shares for which Options have
theretofore been exercised), the Committee shall make a pro rata allocation of
the available remaining shares in as nearly a uniform manner as shall be
practicable and any balance of payroll deductions credited to the accounts of
Participants which have not been applied to the purchase of shares of Stock
shall be paid to such Participants in cash in one lump sum within sixty (60)
days after the Date of Exercise, without any interest thereon.

5.  WITHDRAWAL FROM THE PLAN

     (a) General Statement. Any Participant may withdraw from participation
under the Plan at any time except that no Participant may withdraw during the
last ten (10) days of any Offering Period.  A Participant who wishes to withdraw
from the Plan must deliver to the Company a notice of withdrawal in a form
prepared by the Company (the "Withdrawal Election") not later than ten (10) days
prior to the Date of Exercise during any Offering Period.  Upon receipt of a
Participant's Withdrawal Election, the Company shall pay to the Participant the
amount of the balance in the Participant's account under the Plan in cash in one
lump sum within sixty (60) days, without any interest thereon.  Upon receipt of
a Participant's Withdrawal Election by the Company, the Participant shall cease
to participate in the Plan and the Participant's Option shall terminate.

     (b) Eligibility Following Withdrawal.  A Participant who withdraws from the
Plan and who is still an Eligible Employee shall be eligible to participate
again in the Plan as of any subsequent Date of Grant by delivering to the
Company an Authorization pursuant to Section 3(b) hereof.

6.  TERMINATION OF EMPLOYMENT

     (a) Termination of Employment Other than by Death.  If the employment of a
Participant terminates other than by death, the Participant's participation in
the Plan automatically and without any act on the Participant's part shall
terminate as of the date of the termination of the Participant's employment.  As
soon as practicable after such a termination of employment, the Company will pay
to the Participant the amount of the balance in the Participant's account under
the Plan without any interest thereon.  Upon a Participant's termination of
employment covered by this Section 6(a), the Participant's Authorization,
interest in the Plan and Option under the Plan shall terminate.

     (b) Termination By Death. If the employment of a participant is terminated
by the Participant's death, the executor of the Participant's will or the
administrator of the Participant's estate by written notice to the Company may
request payment of the balance in the Participant's account under the Plan, in
which event the Company shall make such payment without any interest thereon as
soon as practicable after receiving such notice; upon receipt of such notice the
Participant's Authorization, interest in the Plan and Option under the Plan
shall terminate.  If the Company does not receive such notice prior to the next
Date of Exercise, the Participant's Option shall be deemed to have been
exercised on such Date of Exercise.

                                       4

 
7.  RESTRICTION UPON ASSIGNMENT

     An Option granted under the Plan shall not be transferable other than by
will or the laws of descent and distribution, and is exercisable during the
Participant's lifetime only by the Participant.  Except as provided in Section
6(c) hereof, an Option may not be exercised to any extent except by the
Participant.  The Company shall not recognize and shall be under no duty to
recognize any assignment or alienation of the Participant's interest in the
Plan, the Participant's Option or any rights under the Participant's Option.

8.  NO RIGHTS OF STOCKHOLDERS UNTIL CERTIFICATE ISSUED

     With respect to shares of Stock subject to an Option, a Participant shall
not be deemed to be a stockholder of the Company, and the Participant shall not
have any of the rights or privileges of a stockholder, until a certificate for
such shares has been issued to the Participant following exercise of the
Participant's Option.  No adjustments shall be made for dividends (ordinary or
extraordinary, whether in cash securities, or other property) or distribution or
other rights for which the record date occurs prior to the date such certificate
is issued, except as otherwise expressly provided herein.

9.  CHANGES IN THE STOCK; ADJUSTMENTS OF AN OPTION

     Whenever any change is made in the Stock or to Options outstanding under
the Plan, by reason of a stock split, stock dividend, recapitalization or other
subdivision, combination, or reclassification of shares, appropriate action
shall be taken by the Committee to adjust accordingly the number of shares of
Stock subject to the Plan and the number and the Option Price of shares of Stock
subject to the Options outstanding under the Plan to preserve, but not increase,
the rights of Participants hereunder.

10.  USE OF FUNDS; NO INTEREST PAID

     All funds received or held by the Company under the Plan shall be included
in the general funds of the Company free of any trust or other restriction and
may be used for any corporate purpose.  No interest will be paid to any
Participant or credited to any Participant's account under the Plan with respect
to such funds.

11.  AMENDMENT OF THE PLAN

     The Board of Directors may amend, suspend, or terminate the Plan at any
time and from time to time, provided that approval by a vote of the holders of
more than 50% of the outstanding shares of the Company's capital stock entitled
to vote shall be required to amend the Plan (i) to change the number of shares
of Stock reserved for sale pursuant to Options under the Plan, (ii) to decrease
the Option Price below a price computed in the manner stated in Section 4(b)
hereof, (iii) to alter the requirements for eligibility to participate in the
Plan or (iv) in any manner that would cause the Plan to no longer be an
"employee stock purchase plan" within the meaning of Section 423(b) of the Code.

12.  ADMINISTRATION BY COMMITTEE; RULES AND REGULATIONS

     (a) Appointment of Committee.  The Plan shall be administered by the
Committee, which shall be composed of not less than two members of the Board of
Directors, none of whom shall be eligible to serve on the Committee unless such
member is then a "disinterested person" within the meaning of paragraph (d)(3)

under the Securities Exchange Act of 1934, as amended, if and as such rule is
then in effect.  Each member of the Committee shall serve for a term commencing

revoke any such rules.  In its absolute discretion, the Board may at any time
and from time to time exercise any and all rights and duties of the Committee
under the Plan.

     (c) Majority Rule. The Committee shall act by a majority of its members in
office.  The Committee may act either by vote at a meeting or by a memorandum or
other written instrument signed by a majority of the Committee.

     (d) Compensation; Professional Assistance; Good Faith Actions. All expenses
and liabilities incurred by members of the Committee in connection with the
administration of the Plan shall be borne by the Company.  The Committee may,
with the approval of the Board, employ attorneys, consultants, accountants,
appraisers, brokers or other persons.  The Committee, the Company and its
officers and directors shall be entitled to rely upon the advice, opinions or
valuations of any such persons.  All actions taken and all interpretations and
determinations made by the Committee in good faith shall be final and binding
upon all Participants, the Company and all other interested persons.  No member
of the Committee shall be personally liable for any action, determination or
interpretation made in good faith with respect to the Plan or the Options, and
all members of the Committee shall be fully protected by the Company in respect
to any such action, determination, or interpretation.

13.  NO RIGHTS AS AN EMPLOYEE

     Nothing in the Plan shall be construed to give any person (including any

of the Company, the Date of Exercise with respect to outstanding Options shall
be the business day immediately preceding the effective date of such merger,
consolidation, acquisition, liquidation, dissolution, or reorganization unless
the Committee shall, in its sole discretion, provide for the assumption or
substitution of such Options in a manner complying with Section 424(a) of the
Code.

15.  TERM; APPROVAL BY STOCKHOLDERS

     No Option may be granted during any period of suspension of the Plan or
after termination of the Plan. The Plan shall be submitted for the approval of
the Company's stockholders within 12 months after the date of the Board of
Directors' adoption of the Plan.  Options may be granted prior to such
stockholder approval; provided, however, that such Options shall not be
exercisable prior to the time when the Plan is approved by the stockholders; and
provided, further, that if such approval has not been obtained by the end of
said 12-month period, all Options previously granted under the Plan shall
thereupon expire.

16.  EFFECT UPON OTHER PLANS

     The adoption of the Plan shall not affect any other compensation or
incentive plans in effect for the Company, any Parent Corporation or any
Subsidiary Corporation.  Nothing in this Plan shall be construed to limit the
right of the Company, any Parent Corporation or any Subsidiary Corporation (a)
to establish any other forms of incentives or compensation for employees of the
Company, any Parent Corporation or any Subsidiary Corporation or (b) to grant or
assume options otherwise than under this Plan in connection with any proper
