Plan pursuant to the Corporations Bylaws and Nevada Corporate Law.  The
effective date of the Plan shall be March 24, 1998 (the "Effective Date"),
provided that the Plan receives shareholder approval.


IV.  ADMINISTRATION

     The Plan shall be administered by the Board in compliance with Rule 16b-3,
or by a Committee appointed by the Board, which Committee shall be constituted
to permit the Plan to comply with Rule 16b-3, and which shall consist of not
less than two members.  The Board shall appoint one of the members of the
Committee, if there be one, as Chairman of the Committee.  If a Committee has
been appointed, the Committee shall hold meetings at such times and places as it
may determine.  Acts of a majority of the Committee at which a quorum is
present, or acts reduced to or approved in writing by a majority of the members
of the Committee, shall be the valid acts of the Committee.  The Board, or the
Committee if there be one, shall from time to time at its discretion select the

number of Shares to be applicable to such Award, and designate any Options as
Incentive Stock Options or Nonstatutory Stock Options, except that no Incentive
Stock Option may be granted to a non-employee director or a non-employee
consultant.  A member of the Board or a Committee member shall in no event
participate in any determination relating to Awards held by or to be granted to
such Board or Committee member; however, a member of the Board or a Committee
member shall be entitled to receive Awards which are duly approved in accordance
with the provisions of Rule 16b-3.  The interpretation and construction by the
Board, or by the Committee if there be one, of any provision of the Plan or of
any Award granted thereunder shall be final.  No member of the Board or of the
Committee shall be liable for any action or determination made in good faith
with respect to the Plan or any Award granted thereunder.  In addition to any
right of indemnification provided by the Articles of Incorporation or Bylaws of
the Corporation, such person shall be indemnified and held harmless by the
Corporation from any loss, cost, liability or expense that may be imposed upon
or reasonably incurred by him in connection with any claim, suit, action or
proceeding to which he may be a party by reason of any action or omission under
the Plan.


V.   PARTICIPATION

     5.1  Eligibility.  Subject to the terms and conditions of Section 5.2
below, the Participants shall be such persons as the shareholders may approve or
as the Board or the Committee may select from among the following classes of
persons:   (i) Employees of the Corporation or of a Subsidiary (who may be
officers, whether or not they are directors); and (ii) Consultants, vendors,
customers, and others expected to provide significant services to the
Corporation or a Subsidiary.

     For purposes of this Plan, a Participant who is a director or a consultant,
vendor, customer, or other provider of significant services to the Corporation
or a Subsidiary shall be deemed to be an Eligible Employee, and service as a
director, consultant, vendor, customer, or other provider of significant
services to the Corporation or a Subsidiary shall be deemed to be employment,
except that no Incentive Stock Option may be granted to a non-employee director
or non-employee consultant, vendor, customer, or other provider of significant
services to the Corporation or a Subsidiary, and except that no Nonstatutory
Stock Option may be granted to a non-employee director or non-employee
consultant, vendor, customer, or other provider of significant services to the
Corporation or a Subsidiary other than upon a vote of a majority of
disinterested directors finding that the value of the services rendered or to be
rendered to the Corporation or a Subsidiary by such non-employee director or
non-employee consultant, vendor, customer, or other provider of services is at
least equal to the value of the Awards granted.

     5.2  Ten-Percent Shareholders.  An Eligible Employee who owns more than 10%
of the total combined voting power of all classes of outstanding stock of the
Corporation, its parent or any of its Subsidiaries shall not be eligible to
receive an Award for an Incentive Stock Option unless (i) the Exercise Price of
the Shares subject to such Award is at least 110% of the Fair Market Value of
such Shares on the date of grant; and (ii) such Award by its terms is not
exercisable after the expiration of 5 years from the date of grant.

     5.3  Stock Ownership.  For purposes of Section 5.2 above, in determining
stock ownership an Eligible Employee shall be considered as owning the stock
owned, directly or indirectly, by or for his brothers, sisters, spouses,
ancestors, and lineal descendants.  Stock owned, directly or indirectly, by or
for a corporation, partnership, estate, or trust shall be considered as being
owned proportionately by or for its shareholders, partners, or beneficiaries.
Stock with respect to which such Eligible Employee holds an Award shall not be
counted.


                                       3


     5.4  Outstanding Stock.  For purposes of Section 5.2 above, "outstanding
stock" shall include all stock actually issued and outstanding immediately after
the grant of the Award to the Participant.  "Outstanding stock" shall not
include shares authorized for issue under outstanding Options or Purchase Rights
held by the Participant or by any other person.


VI.  STOCK SUBJECT TO THE PLAN

     The stock subject to Awards granted under the Plan shall be Shares of the
Corporation's authorized but unissued or reacquired Common  Stock.  The
aggregate number of Shares which may be issued as Awards or upon exercise of
Awards under the Plan shall not exceed 2,500,000 shares.  The number of Shares
subject to unexercised Options (plus the number of Shares previously issued
under the Plan) shall not at any time exceed the number of Shares available for
issuance under the Plan.  In the event that any unexercised Option, or any
portion thereof, for any reason expires or is terminated, the unexercised or
unvested Shares allocable to such Option may again be made subject to any Award.
Any Shares withheld by the Corporation pursuant to Section 9.3 shall not be
deemed to be issued.  The number of withheld Shares shall be deducted from the
applicable Award and shall not entitle the Participant to receive additional
Shares.  The limitations established by this Article VI shall be subject to
adjustment in the manner provided in Section 8.5 hereof upon the occurrence of
an event specified therein.


VII. OPTIONS

     7.1  Stock Option Agreements.  Options shall be evidenced by written Stock
Option Agreements in such form as the Board or the Committee shall from time to
time determine.  Such agreements shall comply with and be subject to the terms
and conditions set forth below.

     7.2  Type and Number of Shares.  Each Option shall state the type of Award
and the number of Shares to which it pertains and shall provide for the
adjustment thereof in accordance with the provisions of Section 8.5 hereof.

     7.3  Exercise Price.  Each Option shall state the Exercise Price thereof.
The Exercise Price in the case of any Incentive Stock Option shall not be less
than the Fair Market Value on the date of grant and, in the case of any Option
granted to an Optionee described in Section 5.2 hereof, shall not be less than
110% of the Fair Market Value on the date of grant.  The Exercise Price in the
case of any Nonstatutory Stock Option shall not be less than 85% of the Fair
Market Value on the date of grant.

     7.4  Medium and Time of Payment.  The Purchase Price shall be payable in
full in United States dollars upon the exercise of the Option; provided,
however, that if the applicable Stock Option Agreement so provides the Purchase
Price may be paid (i) by the surrender of Shares in good form for transfer,
owned by the Participant and having a Fair Market Value on the date of exercise
equal to the Purchase Price, or in any combination of cash and Shares, as long
as the sum of the cash so paid and the Fair Market Value of the Shares so
surrendered equal the Purchase Price, (ii) by cancellation of indebtedness owed
by the Corporation to the Participant, (iii) with a full recourse promissory
note executed by the Participant, or (iv) any combination of the foregoing.  The
interest rate and other terms and conditions of such note shall be determined by
the Board of Directors.  The Board of Directors may require that the Participant
pledge his or her Shares to the Corporation for the purpose of securing the
payment of such note.  In no event shall the stock certificate(s) representing
such Shares be released to the Participant until such note is paid in full.

     7.5  Term and Nontransferability of Options.  Each Option shall state the
time or times which all or part thereof becomes exercisable.  No Option shall be
exercisable after the expiration of 10 years from the date it was granted, and
no Option granted to a Participant described in Section 5.2 hereof shall be
exercisable after the expiration of five years from the date it was granted.
During the lifetime of the Participant, the Option shall be exercisable only by
the Participant and shall not be assignable or transferable.  In the event of
the Participant's death, the Option shall not be transferable by the Participant
other than by will or the laws of descent and distribution.

     7.6  Modification, Extension, and Renewal of Option.  Within the
limitations of the Plan, the Board of Directors may modify, extend or renew
outstanding Options or accept the cancellation of outstanding Options (to the
extent not previously exercised) for the granting of new Options in substitution
therefor.  The foregoing notwithstanding, no modification of an Option shall,
without the consent of the Participant, alter or impair any rights or
obligations under any Option previously granted.

     7.7  Limitation on Grant of Incentive Stock Options.  In the case of
Incentive Stock Options granted hereunder, the aggregate Fair Market Value
(determined as of the date of the grant thereof) of the Shares with respect to
which Incentive Stock Options become exercisable by any Participant for the
first time during any calendar year (under this Plan and all other Plans
maintained by the Corporation, its parent, or its Subsidiaries) shall not exceed
$100,000.  The Board or Committee may, however, with the Participant's consent
authorize an amendment to the Incentive Stock Option which renders it a
Nonstatutory Stock Option.

     7.8  Other Provisions.  The Stock Option Agreements authorized under the
Plan may contain such other provisions not inconsistent with the terms of the
Plan (including, without limitation, restrictions upon the exercise of the
Option) as the Board of Directors shall deem advisable.


                                       4


     7.9  Specific Awards Approved by the Shareholders.  Subject to shareholder
approval and pursuant to the Board of Director's approval on March 24, 1998, the
individuals whose names are set forth in Exhibit "A," a copy of which is
attached hereto and incorporated herein by this reference, shall be deemed
granted Nonstatutory Stock Options as of the Effective Date, in the amounts and
for the exercise price specified by the Board of Directors, all in accordance
with the provisions set forth in this Article VII of the Plan.  The provisions
of this Section 7.9 shall not be amended more than once every six months, other
than to comply with changes in the Internal Revenue Code, the Employee
Retirement Income Security Act, or the rules thereunder, and are intended to be
construed in accordance with the provisions pertaining to "formula awards" under
Paragraph (c)(2)(ii) of Rule 16b-3.


XIII.     RIGHTS OF ELIGIBLE EMPLOYEES, PARTICIPANTS, AND BENEFICIARIES

     8.1   Employee Status.  Status as an Eligible Employee shall not be
construed as a commitment that any Award will be made under the Plan to an
Eligible Employee or to Eligible Employees generally.

     8.2  No Employment Contract.  Nothing contained in the Plan (or in the
Award Agreements or in any other documents related to the Plan or to Awards)
shall confer upon any Eligible Employee or any Participant any right to continue
in the employ of the Corporation or constitute any contract or agreement of
employment, or interfere in any way with the right of the Corporation to reduce
such person's compensation or to terminate the employment of such Eligible
Employee or Participant, with or without cause, but nothing contained in the
Plan or any document  related thereto shall affect any other contractual right
of any Eligible Employee or Participant.  Nothing contained in the Plan (or in
the Award Agreements or in any other documents related to the Plan or the
Awards) shall confer upon any director of the Corporation any right to continue
as a director of the Corporation.

     8.3  No Transferability.  Awards may be exercised only by, and amounts 
payable or shares issuable pursuant to an Award shall be paid only to or 
registered only in the name of, the Participant or, in the event of the 
Participant's death, to the Participant's Beneficiary or, in the event of the 
Participant's Disability, to the Participant's Personal Representative or, if 
there is none, to the Participant.  Other than by will or the laws of descent 
and distribution, no right or benefit under the Plan or any Award, including, 
without limitation, any Option or share of Restricted Stock that has not 
vested, shall be subject in any manner to anticipation, alienation, sale, 
transfer, assignment, pledge, encumbrance, or charge and any such attempted 
action shall be void and no such right or benefit shall be, in any manner, 
liable for, or subject to, debts, contract, liabilities, engagements, or 
torts of any Eligible Employee, Participant, or Beneficiary, in any case 
except as may otherwise be expressly required by applicable law.  The Board 
or the Committee shall disregard any attempt at transfer, assignment, or 
other alienation prohibited by the preceding sentence and shall pay or 
deliver such cash or shares of Common Stock in accordance with the provisions 
of the Plan.  Notwithstanding the foregoing, the Board or the Committee may 
authorize exercise by or transfers or payments to a third party in a specific 
case or more generally; provided, however, with respect to any option or 
similar right (including any Stock Appreciation Right), such discretion may 
only be exercised to the extent that applicable rules under Section 16 of the 
Exchange Act would so permit without disqualifying the Plan from certain 
benefits thereunder.

     8.4  Plan Not Funded.  No Participant, Beneficiary, or other person 
shall have any right, title, or interest in any fund or in any specific asset 
(including shares of Common  Stock) of the Corporation by reason of any Award 
granted hereunder.  There shall be no funding of any benefits which may 
become payable hereunder.  Neither the provisions of the Plan (or of any 
documents related hereto), nor the creation or adoption of the Plan, nor any 
action taken pursuant to the provisions of the Plan shall create, or be 
construed to create, a trust of any kind or a fiduciary relationship between 
the Corporation and any Participant, Beneficiary, or other person.  To the 
extent that a Participant, a Beneficiary, or other person acquires a right to 
receive an Award hereunder, such right shall be no greater than the right of 
any unsecured general creditor of the Corporation.  Awards payable under the 
Plan shall be paid in shares of Common  Stock or from the general assets of 
the Corporation, and no special or separate fund or deposit shall be 
established and no segregation of assets or shares shall be made to assure 
payment of such Awards.

     8.5  Adjustment Upon Recapitalizations and Corporate Changes.  If the 
outstanding shares of Common  Stock are changed into or exchanged for cash or 
a different number or kind of shares or securities of the Corporation, or if 
the outstanding shares of the Common  Stock are increased, decreased, 
exchanged for, or otherwise changed, or if additional shares or new or 
different shares or securities are distributed with respect to the 
outstanding shares of the Common Stock, through a reorganization or merger in 
which the Corporation is the surviving entity or through a combination, 
consolidation, recapitalization, reclassification, stock split, stock 
dividend, reverse stock split, stock consolidation, or other capital change 
or adjustment, an appropriate adjustment shall be made in the number and kind 
of shares of other consideration that is subject to or may be delivered under 
the Plan and pursuant to outstanding Awards.  A corresponding adjustment to 
the consideration payable with respect to Awards granted prior to any such 
change and to the price, if any, to be paid in connection with Restricted 
Stock Awards shall also be made as appropriate. Corresponding adjustments 
shall be made with respect to Stock Appreciation Rights related to Options to 
which they are related.  In addition, the Board or the Committee may grant 
such additional rights in the foregoing circumstances as the Board or the 
Committee deems to be in the best interest of any Participant and the 
Corporation in order to preserve for the Participant the benefits of an Award.

     8.6  Termination of Employment, Except by Death, Disability, or 
Retirement. If a Participant ceases to be an Employee for any reason other 
than his or her death, Disability or Retirement, such Participant shall have 
the right, subject to the restrictions of Section 8.3 above, to exercise any 
Award at any time within three months after termination of employment, but 
only to the extent that, at the date of termination of employment, the 
Participant's right to exercise such 


                                       5


Award had accrued pursuant to the terms of the applicable agreement and had 
not previously been exercised; provided, however, that if the Participant was 
terminated for cause (as defined in the applicable agreement), any Award not 
exercised in full prior to such termination shall be canceled. For this 
purpose, the employment relationship shall be treated as continuing intact 
while the Participant is on military leave, sick leave, or other bona fide 
leave of absence (to be determined in the sole discretion of the Board or the 
Committee).  The foregoing notwithstanding, in the case of an Incentive Stock 
Option, employment shall not be deemed to continue beyond the 90th day after 
the Participant's reemployment rights are guaranteed by statute or by 
contract.

     8.7  Death of Participant.  If a Participant dies while an Employee, or
after ceasing to be an Employee but during the period while he or she could have
exercised the Award under this Section 8.7, and has not fully exercised the
Award, then the Award may be exercised in full at any time within 12 months
after the Participant's death (but not later than the date of termination fixed
in the applicable agreement), by the executors or administrators of his or her
estate or by any person or persons who have acquired the Award directly from the
Participant by bequest or inheritance, but only to the extent that, at the date
of death, the Participant's right to exercise such Award had accrued and had not
been forfeited pursuant to the terms of the applicable agreement and had not
previously been exercised.

     8.8  Disability of Participant.  If a Participant ceases to be an Employee
by reason of Disability, such Participant shall have the right to exercise the
Award at any time within 12 months after termination of employment (but not
later than the termination date fixed in the applicable Agreement), but only to
the extent that, at the date of termination of employment, the Participant's
right to exercise such Award had accrued pursuant to the terms of the applicable
Award Agreement and had not previously been exercised.

     8.9  Retirement of Participant.  If a Participant ceases to be an Employee
by reason of Retirement, such Participant shall have the right to exercise the
Award at any time within three  months after termination of employment (but not
later than the termination date fixed in the applicable Award Agreement), but
only to the extent that, at the date of termination of employment, the
Participant's right to exercise such Award had accrued pursuant to the terms of
the applicable Award Agreement and had not previously been exercised.

     8.10 Rights as a Stockholder.  A Participant, or a transferee of a
Participant, shall have no rights as a stockholder with respect to any Shares
covered by his or her Award until the date of the issuance of a stock
certificate for such Shares.  No adjustment shall be made for dividends
(ordinary or extraordinary, whether in cash, securities, or other property),
distributions or other rights for which the record date is prior to the date
such stock certificate is issued, except as provided in Section 8.5 hereof.

     8.11 Deferral of Payments.  The Board or the Committee may approve the
deferral of any payments that may become due under the Plan.  Such deferrals
shall be subject to any conditions, restrictions, or requirements as the Board
or the Committee may determine.

     8.12 Acceleration of Awards.  Immediately prior to the occurrence of an 
Event, (i) each Option and Stock Appreciation Right under the Plan shall 
become exercisable in full; (ii) Restricted Stock delivered under the Plan 
shall immediately vest free of restrictions; and (iii) each other Award 
outstanding under the Plan shall be fully vested or exercisable, unless, 
prior to the Event, the Board or the Committee otherwise determines that 
there shall be no such acceleration or vesting of an Award or otherwise 
determines those Awards which shall be accelerated or vested and to the 
extent to which they shall be accelerated or vested, or that an Award shall 
terminate, or unless in connection with such Event the Board provides (A) for 
the assumption of such Awards theretofore granted; or (B) for the 
substitution for such Awards of new awards covering securities or obligations 
(or any combination thereof) of a successor corporation, or a parent or 
subsidiary thereof, with appropriate adjustments as to number and kind of 
shares and prices; or (C) for the payment of the fair market value of the 
then outstanding Awards.  In addition, the Board or the Committee may grant 
such additional rights in the foregoing circumstances as the Board or the 
Committee deems to be in the best interest of the Participant and the 
Corporation in order to preserve for the Participant the benefits of an 
Award.  For purposes of this Section 8.12 only, Board shall mean the Board of 
Directors of the Corporation as constituted immediately prior to the Event.  
In addition, the Board may in its sole discretion accelerate the 
exercisability or vesting of any or all Awards outstanding under the Plan in 
circumstances under which the Board or the Committee determines such 
acceleration appropriate.

IX.  MISCELLANEOUS

     9.1  Termination, Suspension, and Amendment.  The Board or the Committee
may, at any time, suspend, amend, modify, or terminate the Plan (or any part
thereof) and may, with the consent of a Participant, authorize such
modifications of the terms and conditions of such Participant's Award as it
shall deem advisable; provided that, except as permitted under the provisions of
Section 8.5 hereof, no amendment or modification of the Plan may be adopted
without approval by a majority of the outstanding shares of Common Stock
pursuant to a shareholder's action taken without a meeting or by a majority of
the shares of the Common  Stock represented (in person or by proxy) at a meeting
of stockholders at which a quorum is present and entitled to vote thereat, if
such amendment or modification would:


                                       6


               (i)  materially increase the benefits accruing to Participants
under the Plan or materially increase the aggregate number of shares which may
be delivered pursuant to Awards granted under the Plan if such action would
require of the Company's shareholders pursuant  to Rule 16b-3 under the Exchange
Act or any successor provision; or

               (ii) materially modify the requirements of eligibility for
participation in the Plan.

Neither adoption of the Plan nor the provisions hereof shall limit the authority
of the Board to adopt other Plans or to authorize other payments of compensation
and benefits under applicable law.  No Awards under the Plan may be granted or
amended during any suspension of the Plan or after its termination.  The
amendment, suspension or termination of the Plan shall not, without the consent
of the Participant, alter or impair any rights or obligations pertaining to any
Awards granted under the Plan prior to such amendment, suspension, or
termination.

     9.2  No Fractional Shares.  No Award or installment thereof shall be
exercisable except in respect of whole shares, and fractional share interests
shall be disregarded.

     9.3  Tax Withholding.  As required by law, federal, state, or local 
taxes that are subject to the withholding of tax at the source shall be 
withheld by the Corporation as necessary to satisfy such requirements.  The 
Corporation is entitled to require deduction from other compensation payable 
to each Participant or, in the alternative:  (i) the Corporation may require 
the Participant to advance such sums; or (ii) if a Participant elects, the 
Corporation may withhold (or require the return of) Shares having the Fair 
Market Value equal to the sums required to be withheld.  If the Participant 
elects to advance such sums directly, written notice of that election shall 
be delivered prior to such exercise and, whether pursuant to such election or 
pursuant to a requirement imposed by the Corporation, payment in cash or by 
check of such sums for taxes shall be delivered within 10 days after the 
exercise date.  If the Participant elects to have the Corporation withhold 
Shares (or be entitled to the return of Shares) having a Fair Market Value 
equal to the sums required to be withheld, the value of the Shares to be 
withheld (or returned) will be equal to the Fair Market Value on the date the 
amount of tax to be withheld (or subject to return) is to be determined (the 
"Tax Date").

     9.4  Restrictions on Elections Made by Participants.  Elections by 
Participants to have Shares withheld (or subject to return) for this purpose 
will be subject to the following restrictions:  (i) the election must be made 
prior to the Tax Date; (ii) the election must be irrevocable; (iii) the 
election will be subject to the Board's disapproval; and (iv) if the 
Participant is an "officer" within the meaning of Section 16 of the Exchange 
Act, the election shall be subject to such additional restrictions as the 
Board or the Committee may impose in an effort to secure the benefits of any 
regulations thereunder.

     9.5  Limitations on the Corporation's Obligations.  The Corporation 
shall not be obligated to issue shares and/or distribute cash to the 
Participant upon any Award exercise until such payment has been received or 
Shares have been withheld, unless withholding (or offset against a cash 
payment) as of or prior to the exercise date is sufficient to cover all such 
sums due or which may be due with respect to such exercise.  In addition, the 
Board or the Committee may grant to a Participant a cash bonus  in any amount 
required by federal, state, or local tax law to be withheld with respect to 
an Award.

     9.6  Compliance with Laws.  The Plan, the granting of Awards under the 
Plan, the Stock Option Agreements and Stock Purchase Agreements and the 
delivery of Options, Shares, and Awards (and/or the payment of money or 
Common  Stock) pursuant thereto and the extension of any loans hereunder are 
subject to such additional requirements as the Board or the Committee may 
impose to assure or facilitate compliance with all applicable federal and 
state laws, rules and regulations (including, without limitation, securities 
laws and margin requirements) and to such approvals by any regulatory or 
governmental agency which may be necessary or advisable in connection 
therewith.  In connection with the administration of the Plan or the grant of 
any Award, the Board or the Committee may impose such further limitations or 
conditions as in its opinion may be required or advisable to satisfy, or 
secure the benefits of, applicable regulatory requirements (including those 
rules promulgated under Section 16 of the Exchange Act or those rules that 
facilitate exemption from or compliance with the Securities Act or the 
Exchange Act), the requirements of any stock exchange upon which such shares 
or shares of the same class are then listed, and any blue sky or other 
securities laws applicable to such shares.

     9.7       Governing Laws.  The Plan and all Awards granted under the 
Plan and the documents evidencing Awards shall be governed by, and construed 
in accordance with, the laws of the State of Nevada as the  Corporation's 
principle place of business.

     9.8  Securities Law Requirements.

          (a)  Legality of Issuance.  The issuance of any Shares upon the
exercise of any Option and the grant of any Option shall be contingent upon the
following:

               (i)  the Corporation and the Participant shall have taken all
actions required to register the Shares under the Securities Act of 1933, as
amended (the "Securities Act"), and to qualify the Option and the Shares under
any and all applicable state securities or "blue sky" laws or regulations, or to
perfect an exemption from the respective registration and qualification
requirements thereof;


                                       7


               (ii) any applicable listing requirement of any stock exchange on
which the Common  Stock is listed shall have been satisfied; and

               (iii)     any other applicable provision of state or Federal law
shall have been satisfied.

          (b)  Restrictions on Transfer.  Regardless of whether the offering and
sale of Shares under the Plan has been registered under the Securities Act or
has been registered or qualified under the securities laws of any state, the
Corporation may impose restrictions on the sale, pledge, or other transfer of
such Shares (including the placement of appropriate legends on stock
certificates) if, in the judgment of the Corporation and its counsel, such
restrictions are necessary or desirable in order to achieve compliance with the
provisions of the Securities Act, the securities laws of any state, or any other
law. In the event that the sale of Shares under the Plan is not registered under
the Securities Act but an exemption is available which required an investment
representation or other representation, each Participant shall be required to
represent that such Shares are being acquired for investment, and not with a
view to the sale or distribution thereof, and to make such other representations
as are deemed necessary or appropriate by the Corporation and its counsel.  Any
determination by the Corporation and its counsel in connection with any of the
matters set forth in this Section 9.6(b) shall be conclusive and binding on all
persons.  Stock certificates evidencing Shares acquired under the Plan pursuant
to an unregistered transaction shall bear the following restrictive legend and
such other restrictive legends as are required or deemed advisable under the
provisions of any applicable law:

     THESE SHARES OF COMMON STOCK REPRESENTED HEREBY HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1993, AS AMENDED (THE "ACT"),
     OR APPLICABLE STATE SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE
     UPON EXEMPTIONS FROM SUCH REGISTRATION REQUIREMENTS.  THESE SHARES OR
     ANY INTEREST HEREIN MAY NOT, BE OFFERED, SOLD OR TRANSFERRED UNLESS
     REGISTERED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS OR AN
     EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE ACT AND APPLICABLE
     STATE SECURITIES LAWS IS AVAILABLE.

          (c)  Registration or Qualification of Securities.  The Corporation
may, but shall not be obligated to register or qualify the issuance of Awards
and/or the sale of Shares under the Securities Act or any other applicable law.
The Corporation shall not be obligated to take any affirmative action in order
to cause the issuance of Awards or the sale of Shares under the Plan to comply
with any law.

          (d)  Exchange of Certificates.  If, in the opinion of the Corporation
and its counsel, any legend placed on a stock certificate representing shares
issued under the Plan is no longer required, the holder of such certificate
shall be entitled to exchange such certificate for a certificate representing
the same number of Shares but lacking such legend.

     9.9  Execution.  To record the adoption of the Plan in the form set forth
above by the Board effective as of March 24, 1998, the Corporation has caused
this Plan to be executed in the name and on behalf of the Corporation where
provided below by an officer of the Corporation thereunto duly authorized.

                      WRITTEN CONSENT OF THE SHAREHOLDERS OF

                               PENNACO ENERGY, INC.

     The undersigned, being the holders of in excess of the majority of the
outstanding shares of common stock of PENNACO ENERGY, INC., a Nevada corporation
(the "Company"), by this writing do hereby approve and adopt the following
resolutions and consent to  this shareholders' action without a shareholders
meeting, pursuant to the Bylaws of the Company and  Section 78.320 of the Nevada
Revised Statutes as of June 29, 1998:

     RESOLVED, that the 1998 STOCK OPTION AND INCENTIVE PLAN (the "Plan")
     be amended as follows:

     Article VI shall be amended in its entirety to read as follows:

          VI.  STOCK SUBJECT TO THE PLAN The stock subject to Awards
          granted under the Plan shall be Shares of the Corporation's
          authorized but unissued or reacquired Common  Stock.  The
          aggregate number of Shares which may be issued as Awards or
          upon exercise of Awards under the Plan shall not exceed
          4,500,000 shares.  The number of Shares subject to
          unexercised Options (plus the number of Shares previously
          issued under the Plan) shall not at any time exceed the
          number of Shares available for issuance under the Plan.  In
          the event that any unexercised Option, or any portion
          thereof, for any reason expires or is terminated, the
          unexercised or unvested Shares allocable to such Option may
          again be made subject to any Award.  Any Shares withheld by
          the Corporation pursuant to Section 9.3 shall not be deemed
          to be issued.  The number of withheld Shares shall be
          deducted from the applicable Award and shall not entitle the
          Participant to receive additional Shares.  The limitations
          established by this Article VI shall be subject to
          adjustment in the manner provided in Section 8.5 hereof upon
          the occurrence of an event specified therein.

     Article VII Section 7.9 shall be amended in its entirety to read as
     follows:

          7.9  Specific Awards Approved by the Shareholders.  Subject
          to shareholder approval and pursuant to the Board of
          Directors approval, the individuals whose names are set
          forth in Exhibit "A," a copy of which is attached hereto and
          incorporated herein by this reference, shall be deemed
          granted Nonstatutory Stock Options as of the Effective Date,
          in the amounts and for the exercise price specified by the
          Board of Directors, and subject to shareholder approval, the
          individuals whose names are set forth in Exhibit "A-1," a
          copy of which is attached hereto and incorporated herein by
          this reference, shall be deemed granted Nonstatutory Stock
          Options, in the amounts, effective date, and for the
          exercise price specified by the Board of Directors, all in
          accordance with the provisions set forth in this Article VII
          of the Plan.  The provisions of this Section 7.9 with
          respect to the  grant of "formula awards" shall not be
          amended more than once every six months, other than to
          comply with changes in the Internal Revenue Code, the
          Employee Retirement Income Security Act, or the rules
          thereunder, and are intended to be construed in accordance
          with the provisions pertaining to "formula awards" under
          Paragraph (c)(2)(ii) of Rule 16b-3.

     RESOLVED FURTHER, that the foregoing amendments to the Plan be and
     they hereby are approved, adopted, and ratified in all respects;

     FURTHER RESOLVED, that the specific awards, as set forth in all
     exhibits attached to and incorporated by reference into the Plan and
     attached hereto, made apart hereof, and designated as Exhibit "X," be
     and they hereby are approved, adopted, and ratified in all respects;
     and

     FURTHER RESOLVED, that all the actions taken by the Board of Directors
     and the officers of the Company with respect to awarding options and
     the signing of individual option agreements pursuant  to the Plan be
     and they hereby are approved, adopted, and ratified in all respects.
