option will perform, services in advising or 


                                     - 3 -



consulting with respect to the management, operation and development of the 
Company or any Subsidiary, and significantly contributed, are significantly 
contributing or are expected to significantly contribute to the achievement

time one or more Options, as may be determined by the Committee in its sole 
discretion.  The number, type, terms and conditions of the Options granted to 
various Eligible Participants need not be uniform, consistent or in 
accordance with any plan, regardless of whether such Eligible Participants 
are similarly situated.  Upon determination by the Committee that an Option 
is to be granted to an Eligible Participant, written notice shall be given 
such person, specifying the terms, conditions, rights and duties related 
thereto.  Each Eligible Participant to whom an Option is to be granted shall 
enter into an agreement with the company, in such form as the Committee shall 
determine and which is consistent with the provisions of the Plan, specifying 
such terms, conditions, rights and duties.  Options shall be deemed to be 
granted as of the date specified in the grant resolution of the Committee, 
and the related option agreements shall be dated as of such date.

                             III.  Administration

     A.   COMMITTEE.  The Committee, if appointed by the Board, will 
administer this Plan.  If the Board, in its discretion, does not appoint such 
a committee, the Board itself will administer this Plan and take such other 
actions as the Committee is authorized to take hereunder; provided that the 
Board may take such actions hereunder in the same manner as the Board may 
take other actions under the Company's articles of incorporation and by-laws 
generally.

     A majority of the Committee shall constitute a quorum.  Action of such 
Committee may be taken without a meeting if unanimous written consent is 
given. Such committee shall act by majority approval of the members, shall 
keep minutes of its meetings and written action, and shall provide copies of 
such minutes to the Board.  Copies of the minutes and written action shall be 
kept with the written records of the Company.

     From and after the date on which the Company first registers a class of 
its equity securities under Section 12 of the 1934 Act, the Plan shall be 
administered by the Board, all of whom shall be "disinterested persons" 
within the meaning of Rule 16b-3 under the 1934 Act, or a committee 
consisting solely of not fewer than two members of the Board who are such 
"disinterested persons."

     B.   AUTHORITY AND DISCRETION OF COMMITTEE.  The Committee will have 
full and final authority in its discretion, at any time 


                                     - 4 -



and from time to time, subject only to the express terms, conditions and 
other provisions of the Company's articles of incorporation, by-laws and this 
Plan, and the specific limitations on such discretion set forth herein:

     1.   to select and approve the persons who will be granted Options under
     this Plan from among the Eligible Participants, and to grant to any person
     so selected one or more Options to purchase such number of shares of Option
     Stock as the Committee may determine;

     2.   to determine the period or periods of time during which Options may be
     exercised, the Option Price and the duration of such Options, and other
     matters to be determined by the Committee in connection with specific
     Option grants and Option Agreements as specified under this Plan;

     3.   to interpret this Plan, to prescribe, amend and rescind rules and
     regulations relating to this Plan, and to make all other determinations
     necessary or advisable for the operation and administration of this Plan;
     and

     4.   to delegate all or a portion of its authority under subsections 1, 2
     and 3 of this Section III to one or more directors of the Company who are
     executive officers of the Company, but only in connection with Options
     granted to Eligible Participants who are not subject to the reporting and
     liability provisions of Section 16 of the 1934 Act, and the rules and
     regulations thereunder, and subject to such restrictions and limitations
     (such as the aggregate number of shares of Option Stock called for by such
     Options that may be granted) as the Committee may decide to impose on such
     delegate directors.

     C.   LIMITATION ON AUTHORITY.  Notwithstanding the foregoing, or any 
other provision of this Plan, the Committee will have no authority:

     1.   to grant Options to any of its members, whether or not approved by the
     Board; and

     2.   to determine any matters, or exercise any discretion, in connection
     with the Options, to the extent that the power to make such determinations
     or to exercise such discretion would cause one or more members of the
     Committee no longer to be "disinterested persons" within the meaning of
     Section III.A. above.


                                     - 5 -



     D.   DESIGNATION OF OPTIONS.  Except as otherwise provided herein, the 
Committee will designate any Option granted hereunder as an NSO.

     E.   OPTION AGREEMENTS.  Options will be deemed granted hereunder only 
upon the execution and delivery of an Option Agreement by the Optionee and a 
duly authorized executive officer of the Company.  Options will not be deemed 
granted hereunder merely upon the authorization of such grant by the 
Committee.


                       IV.  Shares Reserved for Options

     A.   OPTION POOL.  The aggregate number of shares of Option Stock that 
may be issued pursuant to the exercise of Options granted under this Plan 
shall be Seven Hundred Fifty Thousand (750,000) (the "Option Pool"), provided 
that such number will be increased by the number of shares of Option Stock 
that the Company subsequently may reacquire through repurchase or otherwise.  
Shares of Option Stock that would have been issuable pursuant to Options, but 
that are no longer issuable because all or part of those Options have 
terminated or expired, will be deemed not to have been issued for purposes of 
computing the number of shares of Option Stock remaining in the Option Pool 
and available for issuance.

     The maximum number of shares authorized may also be increased from time 
to time by approval of the Board and, if required pursuant to Rule 16b-3 
under the 1934 Act, Section 422 of the Code, or the applicable rules of any 
securities exchange or NASDAQ and/or NASD, the shareholders of the Company.

     B.   ADJUSTMENTS UPON CHANGES IN STOCK.  In the event of any change in 
the outstanding Stock of the Company as a result of a stock split, reverse 
stock split, stock dividend, recapitalization, combination or 
reclassification, reorganization, merger, consolidation, liquidation, rights 
offering, extraordinary dividend or divesture (including a spin-off) or any 
other change in the corporate structure or shares of the Company, appropriate 
proportionate adjustments will be made (in order to prevent dilution or 
enlargement of Eligible Participants) in:  (1) the aggregate number of shares 
of Option Stock in the Option Pool that may be issued pursuant to the 
exercise of Options granted hereunder; (2) the Option Price and the number of 
shares of Option Stock called for in each outstanding Option granted 
hereunder; and (3) other rights and matters determined on a per share basis 
under this Plan or any Option Agreement hereunder.  Any such adjustments will 
be made only by the Board (or, if the Company is not the surviving 
corporation in any such transaction, the board of directors of the surviving 
corporation), and when so made will be effective, conclusive and binding for 
all purposes with respect to 


                                     - 6 -



this Plan and all options then outstanding.  No such adjustments will be 
required by reason of the issuance or sale by the Company for cash or other 
consideration of additional shares of its Stock or securities convertible 
into or exchangeable for shares of its Stock.

                    V.  Terms of Stock Option Agreements

     Each Option granted pursuant to this Plan will be evidenced by an 
agreement (an "Option Agreement") between the Company and the person to whom 
such Option is granted, in form and substance satisfactory to the Committee 
in its sole discretion, consistent with this Plan.  Without limiting the 
foregoing, each Option Agreement (unless otherwise stated therein) will be 
deemed to include the following terms and conditions:

     A.   COVENANTS OF OPTIONEE.  At the discretion of the Committee, the 
person to whom an Option is granted hereunder, as a condition to the granting 
of the Option, must execute and deliver to the Company a confidential 
information agreement approved by the Committee.  Nothing contained in this 
Plan, any Option Agreement or in any other agreement executed in connection 
with the granting of an Option under this Plan will confer upon any Optionee 
any right with respect to the continuation of his or her status as an 
employee of, officer of, or director of, the Company or its subsidiaries.

     B.   VESTING.  An Option shall become exercisable at such times and in 
such installments (which may be cumulative) as shall be determined by the 
Committee in its sole discretion at the time the Option is granted.  Upon the 
completion of its exercise period, an Option, to the extent not then 
exercised, shall expire.

     C.   EXERCISE OF THE OPTION.

     1.   MECHANICS AND NOTICE.  An Option may be exercised to the extent
     exercisable (a) by giving written notice of exercise to the Company,
     specifying the number of full shares of Option Stock to be purchased and
     accompanied by full payment of the Option Price thereof and the amount of
     withholding taxes pursuant to subsection V.C.2 below; and (b) by giving
     assurances satisfactory to the Company that the shares of Option Stock to
     be purchased upon such exercise are being purchased for investment and not
     with a view to resale in connection with any distribution of such shares in
     violation of the 1933 Act; provided, however, that in the event the Option
     Stock called for under the Option is registered under the 1933 Act, or in
     the event resale of such Option Stock 


                                     - 7 -




     without such registration would otherwise be permissible, this second 
     condition will be inoperative if, in the opinion of counsel for the 
     Company, such condition is not required under the 1933 Act, or any other 
     applicable law, regulation or rule of any governmental agency.

     2.   WITHHOLDING TAXES.  As a condition to the issuance of the shares of
     Option Stock upon full or partial exercise of an Option granted under this
     Plan, the Optionee will pay to the Company in cash, or in such other form
     as the Committee may determine in its discretion, the amount of the
     Company's tax withholding liability required in connection with such
     exercise.  For purposes of this subsection V.C.2, "tax withholding
     liability" will mean all federal and state income taxes, social security
     tax, and any other taxes applicable to the compensation income arising from
     the transaction required by applicable law to be withheld by the Company.

     3.   PAYMENT OF OPTION PRICE.  Each Option Agreement will specify the
     Option Price with respect to the exercise of Option Stock thereunder, to be
     fixed by the Committee in its discretion, but in no event will the Option
     Price for an NSO granted hereunder be less than eighty-five (85%) percent
     of Fair Market Value.  The Option Price will be payable to the Company in
     United States dollars in cash or by check or, such other form of
     consideration as may be approved by the Committee, in its discretion.

     In determining whether or upon what terms and conditions an Eligible
     Participant will be permitted to pay the purchase price of an Option in a
     form other than cash, the Committee may consider all relevant facts and
     circumstances, including, without limitation, the tax and securities law
     consequences to the Company.  In the event the Eligible Participant is
     permitted to pay the purchase price of an Option in whole or in part with
     Previously Acquired Shares and/or the surrender of Options, the value of
     such Previously Acquired Shares and/or the shares covered by such Options
     shall be equal to their Fair Market Value on the date of exercise of the
     Option.

     D.   TERMINATION OF THE OPTION.  Except as otherwise provided herein, 
each Option Agreement will specify the period of time, to be fixed by the 
Committee in its discretion, during which the Option granted therein will be 
exercisable, not to exceed ten years from the date of grant in the case of an 
NSO (the "Option Period"). To the extent not previously exercised, each 
Option will terminate upon the expiration of the Option Period specified in 
the Option Agreement; provided, however, that each such Option will 
terminate, if earlier: (i) ninety days after the date that the Optionee 
ceases 


                                     - 8 -




to be an Eligible Participant for any reason, other than by reason of death 
or disability; (ii) twelve months after the date that the Optionee ceases to 
be an Eligible Participant by reason of such person's death or disability; or 
(iii) twelve months after the date that the Optionee ceases to be an Eligible 
Participant by reason of such person termination of service as a advisor or 
consultant.  In the event of a sale or all or substantially all of the assets 
of the Company, or a merger or consolidation or other reorganization in which 
the Company is not the surviving corporation, or in which the Company becomes 
a subsidiary of another corporation (any of the foregoing events, a 
"Corporate Transaction") , then notwithstanding anything else herein, the 
successor corporation must agree to assume the outstanding Options or 
substitute therefor comparable options of such successor corporation or a 
parent or subsidiary of such successor corporation.

     Unless the committee shall otherwise determine in its sole discretion, 
an Eligible Participant's service shall, for purposes of the Plan, be deemed 
to have terminated on the date such Eligible Participant ceases to perform 
services for the Company and all Subsidiaries, as determined in good faith by 
the Committee.

     E.   OPTIONS NONTRANSFERABLE.  No Option will be transferable by the 
Optionee otherwise than by (i) will or the laws of descent and distribution, 
(ii) pursuant to a qualified domestic relations order (as defined by the 
Code), or (iii) if the Optionee is a corporation, limited liability company, 
or partnership, distribution to the shareholders or partners thereof.  During 
the lifetime of the Optionee, the Option will be exercisable only by 
him/her/it, or the transferee if it was transferred pursuant to this subpart.

     F.   QUALIFICATION OF STOCK.  The right to exercise an Option will be 
further subject to the requirement that if at any time the Board determines, 
in its discretion, that the listing, registration or qualification of the 
shares of Option Stock called for thereunder upon any securities exchange or 
under any state or federal law, or the consent or approval of any 
governmental regulatory authority, is necessary or desirable as a condition 
of or in connection with the granting of such Option or the purchase of 
shares of Option Stock thereunder, the Option may not be exercised, in whole 
or in part, unless and until such listing, registration, qualification, 
consent or approval is effected or obtained free of any conditions not 
acceptable to the Board, in its discretion.

     G.   ADDITIONAL RESTRICTIONS ON TRANSFER.  By accepting Options and/or 
Option Stock under this Plan, the Optionee will be deemed to represent, 
warrant and agree as follows:


                                     - 9 -




     1.   SECURITIES ACT OF 1933.  The Optionee understands that the shares of
     Option Stock have not been registered under the 1933 Act, and that such
     shares are not freely tradeable and must be held indefinitely unless such
     shares are either registered under the 1933 Act or an exemption from such
     registration is available.  The Optionee understands that the Company is
     under no obligation to register the shares of Option Stock.

     2.   OTHER APPLICABLE LAWS.  The Optionee further understands that Transfer
     of the Option Stock requires full compliance with the provisions of all
     applicable law.

     3.   INVESTMENT INTENT.  Unless a registration statement is in effect with
     respect to the sale of Option Stock obtained through exercise of Options
     granted hereunder: (a) Upon exercise of any Option, the Optionee will
     purchase the Option Stock for his/her/its own account and not with a view
     to distribution within the meaning of the 1933 Act, other than as may be
     effected in compliance with the 1933 Act and the rules and regulations
     promulgated thereunder; (b) no one else will have any beneficial interest
     in the Option Stock; and (c) he/ she/it has no present intention of
     disposing of the Option Stock at any particular time.

     H.   COMPLIANCE WITH LAW.  Notwithstanding any other provision of this 
Plan, Options may be granted pursuant to this Plan, and Option Stock may be 
issued pursuant to the exercise thereof by an Optionee, only after there has 
been compliance with all applicable federal and state securities laws, and 
all of the same will be subject to this overriding condition.  The Company 
will not be required to register or qualify Option Stock with the Securities 
and Exchange Commission or any State agency, except that the Company will 
register with, or as required by local law, file for and secure an exemption 
from such registration requirements from, the applicable securities 
administrator and other officials of each jurisdiction in which an Eligible 
Participant would be granted an Option hereunder prior to such grant.

     I.   STOCK CERTIFICATES.  Certificates representing the Option Stock 
issued pursuant to the exercise of Options will bear all legends required by 
law and necessary to effectuate this Plan's provisions.  The Company may 
place a "stop transfer" order against shares of the Option Stock until all 
restrictions and conditions set forth in this Plan have been complied with.

     Unless a registration statement under the 1933 Act and applicable state 
securities laws is in effect with respect to the issuance or transfer of the 
shares of Stock under the Plan, each 

                                    - 10 -




certificate representing any such shares shall be endorsed with a legend in 
substantially the following form, unless counsel for the Company is of the 
opinion as to any such certificate that such legend is unnecessary:

     THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER
     THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR UNDER APPLICABLE
     STATE SECURITIES LAWS.  THESE SECURITIES HAVE ACQUIRED FOR INVESTMENT AND
     MAY NOT BE OFFERED FOR SALE, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, OR
     ENCUMBERED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE
     REGISTRATION STATEMENT UNDER THE ACT AND SUCH STATE LAWS OR PURSUANT TO AN
     EXEMPTION FROM REGISTRATION UNDER THE ACT AND SUCH STATE LAWS, THE
     AVAILABILITY OF WHICH IS TO BE ESTABLISHED TO THE SATISFACTION OF THE
     COMPANY.

     J.   NOTICES.  Any notice to be given to the Company under the terms of 
an Option Agreement will be addressed to the Company at its principal 
executive office, Attention: Corporate Secretary, or at such other address as 
the Company may designate in writing.  Any notice to be given to an Optionee 
will be addressed to the Optionee at the address provided to the Company by 
the Optionee.  Any such notice will be deemed to have been duly given if and 
when enclosed in a properly sealed envelope, addressed as aforesaid, 
registered and deposited, postage and registry fee prepaid, in a post office 
or branch post office regularly maintained by the United States Government.

     K.   OTHER PROVISIONS.  The Option Agreement may contain such other 
terms, provisions and conditions, including such special forfeiture 
conditions, rights of repurchase, rights of first refusal and other 
restrictions on Transfer of Option Stock issued upon exercise of any Options 
granted hereunder, not inconsistent with this Plan, as may be determined by 
the Committee in its sole discretion.

     L.   RIGHTS AS A SHAREHOLDER.  The Eligible Participant shall have no 
rights as a shareholder with respect to any shares of Company Common Stock 
covered by an Option until the Optionee shall have become the holder of 
record of such shares.

     M.   EMPLOYMENT OF SERVICE.  Nothing in this Plan shall interfere with 
or limit in any way the right of the Company or any Subsidiary to terminate 
the service of any Eligible Participant at any time, nor confer upon any 
Eligible Participant any right to continue in the service of the Company or 
any Subsidiary.

     N.   NON-EXCLUSIVITY OF THE PLAN.  Nothing contained in the Plan is
intended to amend, modify or rescind any previously approved compensation plans
or programs entered into by the 


                                    - 11 -




Company.  The Plan will be construed to be in addition to any and all other 
plans or programs.  Neither the adoption of the plan nor the submission of 
the Plan to the shareholders of the Company for approval will be construed as 
creating any limitations on the power or authority of the Board to adopt such 
additional or other compensation arrangements as the Board may deem necessary 
or desirable.

                      VI.  Proceeds from Sale of Stock

     Cash proceeds from the sale of shares of Option Stock issued from time 
to time upon the exercise of Options granted pursuant to this Plan will be 
added to the general funds of the Company and as such will be used from time 
to time for general corporate purposes.

             VII.  Modification, Extension and Renewal of Options
