expire or become unexercisable for any reason without having been exercised 
in full, the unpurchased Shares which were subject thereto shall, unless the

4.   ADMINISTRATION OF THE PLAN.

     (a)  PROCEDURE.  The Plan shall be administered by the Board of 
Directors. The Board of Directors may appoint a Committee consisting of not 
less than two members of the Board of Directors to administer the Plan on 
behalf of the Board of Directors, subject to such terms and conditions as the 
Board of Directors may prescribe.  Once appointed, the Committee shall 
continue to serve until otherwise directed by the Board of Directors.  From 
time to time the Board of Directors may increase the size of the Committee 
and appoint additional members thereof, remove members (with or without 
cause), and appoint new members in substitution therefor, fill vacancies 
however caused and remove all members of the Committee, and thereafter 
directly administer the Plan.  Notwithstanding anything in this Section 4 to 
the contrary, at any time the Board of Directors or the Committee may 
delegate to a committee of one or more members of the Board of Directors the 
authority to grant Options to all Employees and Consultants or any portion or 
class thereof.

     (b)  POWERS OF THE BOARD.  Subject to the provisions of the Plan, the 
Board shall have such authority with regard to the Plan and the options as 
determined by the Board of Directors, including the authority, in its 
discretion: (i) to grant options under the Plan, provided, however, that only 
nonstatutory options may be granted under the Plan; (ii) to determine, upon 
review of relevant information and in accordance with Section 8(c) of the 
Plan, the Fair Market Value of the Common Stock; (iii) to determine the 
exercise price per share of Options to be granted, which exercise price shall 
be determined in accordance with Section 8(a) of the Plan; (iv) to determine 
the Employees or Consultants to whom, and the time or times at which, Options 
shall be granted and the number of Shares to be represented by each Option, 
provided that no Options may be granted to persons who are neither Employees 
nor Consultants; (v) to interpret the Plan; (vi) to prescribe, amend and 
rescind rules and regulations relating to the Plan; (vii) to determine the 
terms and provisions of each Option granted (which need not be identical) in 
accordance with the Plan, and, with the consent of the holder thereof with 
respect to any adverse change, modify or amend each Option; (viii) to 
accelerate or defer (the latter with the consent of the Optionee) the 
exercise date and vesting of any Option; (ix) to authorize any person to 
execute on behalf of the Company any instrument required to effectuate the 
grant of an Option previously granted by the Board; and (x) to make all other 
determinations deemed necessary or advisable for the administration of the 
Plan.

                                      3


     (c)  EFFECT OF BOARD'S DECISION.  All decisions, determinations and 
interpretations of the Board shall be final and binding on all Optionees and 
any other holders of any Options granted under the Plan.

5.   ELIGIBILITY.

     Options may be granted only to Employees or Consultants as defined in 
Section 2 hereof.  An Employee or Consultant who has been granted an Option 
may, if he or she is otherwise eligible, be granted an additional Option or 
Options. Notwithstanding the foregoing, no Employee who is an Officer of the 
Company or who is a member of the Board of Directors shall be entitled to 
receive the grant of an Option under the Plan.  

     The Plan shall not confer upon any Optionee any right with respect to 
continuation of employment or consulting with the Company, nor shall it 
interfere in any way with the Optionee's right or the Company's right to 
terminate the Optionee's employment at any time or the Optionee's consulting 
for the Company pursuant to the terms of the Consultant's agreement with the 
Company.

6.   TERM OF THE PLAN.  

     The Plan shall become effective upon its adoption by the Board of 
Directors.  It shall continue in effect until terminated under Section 13 of 
the Plan.  

7.   TERM OF OPTION.  

     The term of each Option shall be ten (10) years from the date of grant 
thereof or such shorter term as may be provided in the Option Agreement.

8.   EXERCISE PRICE, CONSIDERATION AND VESTING.

     (a)  EXERCISE PRICE.  The per Share exercise price for the Shares to be 
issued pursuant to exercise of an Option shall be no less than 85% of the 
Fair Market Value per Share on the date of grant.  Notwithstanding the 
foregoing, an Option may be granted with an exercise price lower than that 
set forth in the preceding sentence if such Option is granted pursuant to an 
assumption or substitution for another option in a manner satisfying the 
provisions of Section 424(a) of the Code.

     (b)  CONSIDERATION.  The consideration to be paid for the Shares to be 
issued upon exercise of an Option, including the method of payment, shall be 
determined by the Board and may consist entirely of (i) cash or check; (ii) 
other shares of the Common Stock of the Company having a Fair Market Value on 
the date of surrender equal to the aggregate exercise price of the Shares as 
to which the Option shall be exercised, including by delivering to the 
Company an attestation of ownership of owned and unencumbered shares of the 
Common Stock of the Company in a form approved by the Company; (iii) payment 
pursuant to a program developed under Regulation T as promulgated by the 
Federal Reserve Board which, prior to the issuance of Common Stock, results 
in either the receipt of cash (or check) by the Company or the receipt of 

                                      4


irrevocable instructions to pay the aggregate exercise price to the Company 
from the sales proceeds; (iv) any combination of such methods of payment; or 
(v) such other consideration and method of payment for the issuance of Shares 
to the extent permitted under applicable law.  In making its determination as 
to the type of consideration to accept, the Board shall consider if 
acceptance of such consideration may be reasonably expected to benefit the 
Company.

     (c)  VESTING.  The total number of Shares subject to an Option may, but 
need not, be allotted in periodic installments (which may, but need not, be 
equal).  The Option Agreement may provide that, from time to time during each 
of such installment periods, the Option may become exercisable ("vest") with 
respect to some or all of the Shares allotted to that period, and may be 
exercised with respect to some or all of the Shares allotted to such period 
and/or any prior period as to which the Option became vested but was not 
fully exercised.  The Option may be subject to such other terms and 
conditions on the time or times when it may be exercised (which may be based 
on performance or other criteria) as the Board may deem appropriate.  The 
provisions of this Section 8(c) are subject to any Option provisions 
governing the minimum number of Shares as to which an Option may be 
exercised. 

9.   EXERCISE OF OPTION.

     (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER.  Any Option 
granted hereunder shall be exercisable at such times and under such 
conditions as determined by the Board, including performance criteria with 
respect to the Company and/or the Optionee, and as shall be permissible under 
the terms of the Plan.

          An Option shall be deemed to be exercised when written notice of 
such exercise has been given to the Company in accordance with the terms of 
the Option by the person entitled to exercise the Option and full payment for 
the Shares with respect to which the Option is exercised has been received by 
the Company.  Full payment may, as authorized by the Board, consist of any 
consideration and method of payment allowable under Section 8(c) of the Plan. 
Until the issuance (as evidenced by the appropriate entry on the books of the 
Company or of a duly authorized transfer agent of the Company) of the stock 
certificate evidencing such Shares, no right to vote or receive dividends or 
any other rights as a stockholder shall exist with respect to the Optioned 
Stock, notwithstanding the exercise of the Option.  No adjustment will be 
made for a dividend or other right for which the record date is prior to the 
date the stock certificate is issued, except as provided in Section 11 of the 
Plan.  An Option may not be exercised for a fraction of a Share.

          Exercise of an Option in any manner shall result in a decrease in 
the number of Shares which thereafter may be available, both for purposes of 
the Plan and for sale under the Option, by the number of Shares as to which 
the Option is exercised.

          The Option may, but need not, include a provision whereby the 
Optionee may elect at any time while an Employee or Consultant (or while an 
officer or director of the Company) to exercise the Option as to any part or 
all of the shares subject to the Option, subject to a repurchase right in 
favor of the Company on such terms as the Board shall establish.

                                      5


     (b)  TERMINATION OF SERVICE AS AN EMPLOYEE OR CONSULTANT.  If an 
Optionee's Continuous Service as an Employee or Consultant ceases for any 
reason other than death or disability, the Optionee may, but only within 
three (3) months (or such other period of time as is determined by the Board) 
after the date the Optionee's Continuous Service as an Employee or Consultant 
ceases, exercise the Option to the extent that the Optionee was entitled to 
exercise it at the date of such termination.  To the extent that the Optionee 
was not entitled to exercise the Option at the date of such termination, or 
if the Optionee does not exercise such Option (which the Optionee was 
entitled to exercise) within the time specified herein, the Option shall 
terminate.

     (c)  DEATH OF OPTIONEE.  In the event of the death during the term of 
the Option of an Optionee who is at the time of his or her death an Employee 
or Consultant and who shall have been in Continuous Service as an Employee or 
Consultant since the date of grant of the Option, or in the event of the 
death of an Optionee within three (3) months following the termination of the 
Optionee's Continuous Service as an Employee or Consultant for any other 
reason, the Option may be exercised at any time within eighteen (18) months 
(or such other period of time as is determined by the Board) following the 
date of death by the Optionee's estate or by a person who acquired the right 
to exercise the Option by bequest or inheritance, to the extent that the 
Optionee was entitled to exercise it at the date of such termination.  To the 
extent that the Optionee was not entitled to exercise the Option at the date 
of such termination, or if the Option is not exercised (to the extent the 
Optionee was entitled to exercise) within the time specified herein, the 
Option shall terminate.

     (d)  DISABILITY OF OPTIONEE.  In the event of the disability during the 
term of the Option of an Optionee who is at the time of his or her disability 
an Employee or Consultant and who shall have been in Continuous Service as an 
Employee or Consultant since the date of grant of the Option, the Optionee 
may, but only within twelve (12) months (or such other period of time as is 
determined by the Board) after the date the Optionee ceases to be an Employee 
or Consultant on account of such disability, exercise the Option to the 
extent that the Optionee was entitled to exercise it at the date of such 
termination.  To the extent that the Optionee was not entitled to exercise 
the Option at the date of such termination, or if the Optionee does not 
exercise such Option (which the Optionee was entitled to exercise) within the 
time specified herein, the Option shall terminate.

     (e)  WITHHOLDING.  To the extent provided by the terms of the Option 
Agreement, the Optionee may satisfy any federal, state or local tax 
withholding obligation relating to the exercise of such Option by any of the 
following means ( in addition to the Company's right to withhold from any 
compensation paid to Optionee by the Company)or by a combination of such 
means:  (i) tendering a cash payment; (ii) authorizing the Company to 
withhold Shares from the Shares otherwise issuable to the Optionee as a 
result of the exercise of the Option; or (iii) delivering to the Company 
owned and unencumbered shares of the Common Stock of the Company.

10.  TRANSFERABILITY OF OPTIONS.  

                                      6


     Except as otherwise expressly provided in the terms of the Option 
Agreement, the Option may not be sold, pledged, assigned, hypothecated, 
transferred, or disposed of in any manner other than by will or by the laws 
of descent or distribution and may be exercised, during the lifetime of the 
Optionee, only by the Optionee.  Notwithstanding the foregoing, the Optionee 
may, by delivering written notice to the Company, in a form satisfactory to 
the Company, designate a third party who, in the event of the death of the 
Optionee, shall thereafter be entitled to exercise the Option.

11.  ADJUSTMENTS UPON CHANGES IN STOCK.

     (a)  If any change is made in the stock subject to the Plan, or subject 
to any Option, without the receipt of consideration by the Company (through 
merger, consolidation, reorganization, recapitalization, reincorporation, 
stock dividend, dividend in property other than cash, stock split, 
liquidating dividend, combination of shares, exchange of shares, change in 
corporate structure or other transaction not involving the receipt of 
consideration by the Company), the Plan and the outstanding Options will be 
appropriately adjusted in the class(es) and number of securities and price 
per share of stock subject to such outstanding Options.  Such adjustments 
shall be made by the Board, the determination of which shall be final, 
binding and conclusive.  (The conversion of convertible securities, cashless 
exercise of options and net exercise of warrants shall not be treated as 
transactions "without receipt of consideration" by the Company.)

     (b)  In the event of:  (1) a dissolution or liquidation of the Company; 
(2) a merger or consolidation in which the Company is not the surviving 
corporation; or (3) a reverse merger in which the Company is the surviving 
corporation but the shares of the Company's common stock outstanding 
immediately preceding the merger are converted by virtue of the merger into 
other property, whether in the form of securities, cash or otherwise, then, 
subject to paragraph (c) of this Section 11, at the sole discretion of the 
Board and to the extent permitted by applicable law:  (i) any surviving 
corporation shall assume any Options outstanding under the Plan or shall 
substitute similar Options for those outstanding under the Plan, (ii) such 
Stock Awards shall continue in full force and effect, or (iii) the time 
during which such Stock Awards become vested or may be exercised shall be 
accelerated and any outstanding unexercised rights under any Stock Awards 
terminated if not exercised prior to such event. In the event any surviving 
corporation or acquiring corporation refuses to assume such Options or to 
substitute similar Options for those outstanding under the Plan, then with 
respect to Options held by Optionees whose Continuous Service has not 
terminated, the vesting shall be accelerated in full, and the Options shall 
terminate if not exercised at or prior to such event.  With respect to any 
other Options outstanding under the Plan, such Options shall terminate if not 
exercised prior to such event.

     (c)  In the event of either (i) the acquisition by any person, entity or 
group within the meaning of Section 13(d) or 14(d) of the Exchange Act or any 
comparable successor provisions (excluding any employee benefit plan, or 
related trust, sponsored or maintained by the Company or an Affiliate of the 
Company) of the beneficial ownership (within the meaning of Rule 13d-3 
promulgated under the Exchange Act, or comparable successor rule) of 
securities of the Company representing at least fifty percent (50%) of the 
combined voting power entitled to vote

                                      7


in the election of directors, which acquisition has not been approved by 
resolution of the Company's Board of Directors, or (ii) a change in a 
majority of the membership of the Company's Board of Directors within a 
twenty-four (24) month period where the selection of such majority either (A) 
was not approved by a majority of the members of the Board of Directors at 
the beginning of such twenty-four (24) month period or (B) occurred as the 
result of an actual or threatened "Election Contest" (as described in Rule 
14a-11 promulgated under the Exchange Act) or other actual or threatened 
solicitation of proxies or consents by or on behalf of any person other than 
the Board (a "Proxy Contest"), including by reason of any agreement intended 
to avoid or settle any Election Contest or Proxy Contest, then to the extent 
not prohibited by applicable law, the time during which options outstanding 
under the Plan may be exercised shall be accelerated prior to such event, but 
only to the extent that such options would have become exercisable within 
thirty (30) months of the date of such event, and the options terminated if 
not exercised after such acceleration and at or prior to such event.

12.    TIME OF GRANTING OPTIONS.  

       The date of grant of an Option shall, for all purposes, be the date on 
which the Board makes the determination granting such Option.  Notice of the 
determination shall be given to each Employee or Consultant to whom an Option 
is so granted within a reasonable time after the date of such grant.

13.    AMENDMENT AND TERMINATION OF THE PLAN.

       (a)  AMENDMENT AND TERMINATION.  The Board may amend or terminate the 
Plan from time to time in such respects as the Board may deem advisable. 

       (b)  EFFECT OF AMENDMENT OR TERMINATION. Options granted before 
amendment of the Plan shall not be impaired any amendment unless mutually 
agreed otherwise between the Optionee and the Company, which agreement must 
be in writing and signed by the Optionee and the Company.

14.    SECURITIES LAW COMPLIANCE.  

       Notwithstanding any provisions relating to vesting contained herein or 
in an Option, no Option granted hereunder may be exercised unless the shares 
issuable upon exercise of such option are then registered under the 
Securities Act of 1933, as amended.

15.    RESERVATION OF SHARES.  

       The Company, during the term of this Plan, will at all times reserve 
and keep available such number of Shares as shall be sufficient to satisfy 
the requirements of the Plan.

       Inability of the Company to obtain authority from any regulatory body 
having jurisdiction, which authority is deemed by the Company's counsel to be 
necessary to the lawful issuance and sale of any Shares hereunder, shall 
relieve the Company of any liability in respect

                                      8


of the failure to issue or sell such Shares as to which such requisite 
authority shall not have been obtained.

16.    OPTION AGREEMENT.  

       Options shall be evidenced by written Option Agreements in such form 
or forms as the Board or the Committee shall approve.

                                      9
