will perform, services in 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 of corporate
objectives. Eligible Participants may be granted from

                                        4


time to 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 l6b-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 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,

                                        5


         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.

         D. DESIGNATION OF OPTIONS. Except as otherwise provided herein, the
Committee will designate any Option granted hereunder either as an ISO or as an
NSO. To the extent that the Fair Market Value (determined at the time the Option
is granted) of Stock with respect to which all ISOs are exercisable for the
first time by any individual during any calendar year (pursuant to this Plan and
all other plans of the Company and/or its Subsidiaries) exceeds $100,000, such
option will be treated as an NSO. Notwithstanding the general eligibility
provisions of Section II hereof, the Committee may grant ISOs only to persons
who are employees of the Company and/or its Subsidiaries.

                                        6


         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 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.

                                        7


                       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 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

                                        8


         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 ISO granted hereunder be less than
         one hundred (100%) percent of the Fair Market Value (or, in case the
         Optionee is a 10% Stockholder, one hundred ten (110%) percent of such
         Fair Market Value) of the Option Stock at the time such ISO is granted,
         and 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 ISO (the
"Option Period") ; provided that the Option Period will not exceed five years
from the date of grant in the case of an ISO granted to a 10% Stockholder. 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 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) immediately as of the date that the
Optionee ceases to be an Eligible Participant by reason of a Just Cause
Termination. In the event of a sale or all

                                        9


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 right to exercise all then outstanding Options will vest immediately
prior to such Corporate Transaction and will terminate immediately after such
Corporate Transaction; provided, however, that if the Board, in its sole
discretion, determines that such immediate vesting of the right to exercise
outstanding Options is not in the best interests of the Company, then 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 employment or other 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 will or the laws of descent and distribution, or in
the case of an NSO, pursuant to a qualified domestic relations order (as defined
by the Code). During the lifetime of the Optionee, the Option will be
exercisable only by him or her, or the transferee of an NSO if it was
transferred pursuant to a qualified domestic relations order.

         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:

                  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

                                       10


         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 laws.

                  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 or her own account
         and not with a view to distribution within the meaning of the 193 3
         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 or she 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 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

                                       11


         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
employment or service of any Eligible Participant at any time, nor confer upon
any Eligible Participant any right to continue in the employ or 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 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.

Plan, the Committee may modify, extend or renew outstanding Options granted

from time to time; provided that no action of the Board will cause ISOs granted
under this Plan not to comply with Section 422 of the Code unless the Board
specifically declares such action to be made for that purpose and provided
further that no such action may, without the approval of the stockholders of the
Company, materially increase (other than by reason of an adjustment pursuant to
Section IV.B hereof) the maximum aggregate number of shares of Option Stock in
the Option Pool that may be issued under Options granted pursuant to this Plan
or materially increase the benefits accruing to Plan participants or materially
modify eligibility requirements for the participants. Moreover, no such action
may alter or impair any Option previously granted under this Plan without the
consent of the holder of such Option.

                       IX. FLAN COMPLIANCE WITH RULE 16B-3
