                             PARACHUTE TAX AGREEMENT



         This Agreement is made by and between _________________ ("Executive")
and Pennaco Energy, Inc., a Delaware corporation (the "Company"), effective for
all purposes as of November 15, 2000.

         WHEREAS, Executive is a key member of the Company's management; and

         WHEREAS, the Company recognizes that the possibility of a "change in
control" of the Company, within the meaning of Section 280G of the Internal
Revenue Code of 1986, as amended (the "Code"), may arise (hereafter a "Change of
Control"); and

         WHEREAS, such a possibility presents uncertainty for key members of
management that may result in departures or distraction of management to the
detriment of the Company; and

         WHEREAS, as an additional inducement to Executive to continue his
employment with the Company, the Company desires to provide Executive with the
benefits of this Agreement in the event of a Change of Control and Executive
desires to receive such benefits;

         NOW, THEREFORE, the parties hereto agree as follows:

         1.       TAX GROSS-UP BENEFIT.

                  (a) In the event it shall be determined that, as a consequence
         of any Change of Control of the Company, any payment or benefit made or
         provided by the Company or any other person to or for the benefit of
         Executive (a "Payment") would be subject to the excise tax imposed by
         Section 4999 of the Code or any interest or penalties are incurred by
         Executive with respect to such excise tax (such excise tax, together
         with any such interest and penalties, are hereinafter collectively
         referred to as the "Excise Tax"), then Executive shall be entitled to
         receive an additional payment (a "Gross-Up Payment") from the Company
         in an amount such that after payment by Executive of all taxes
         (including any interest or penalties imposed with respect to such
         taxes), including, without limitation, any taxes (and any interest and
         penalties imposed with respect thereto) and Excise Tax imposed upon the
         Gross-Up Payment, Executive retains an amount of the Gross-Up Payment
         equal to the Excise Tax imposed upon the Payment.

                  (b) Subject to the provisions of Paragraph (c) below, all
         determinations required to be made under this Agreement, including
         whether and when a Gross-Up Payment is required and the amount of such
         Gross-Up Payment and the assumptions to be utilized in arriving at such
         determination, shall be made by such nationally recognized certified
         public accounting firm as may be designated by Executive (the
         "Accounting Firm"), which shall provide detailed supporting
         calculations both to the Company and Executive within fifteen business
         days of the receipt of notice from Executive that there has been a
         Payment, or such earlier time as is requested by the Company. In the
         event that the Accounting Firm is serving as accountant or auditor for
         the person effecting the Change of Control, Executive shall appoint
         another nationally recognized accounting




   2

         firm to make the determinations required hereunder (which accounting
         firm shall then be referred to as the Accounting Firm hereunder). All
         fees and expenses of the Accounting Firm shall be borne solely by the
         Company. Any Gross-Up Payment, as determined pursuant to this
         Agreement, shall be paid by the Company to Executive within five days
         of the receipt of the Accounting Firm's determination. Any
         determination by the Accounting Firm shall be binding upon the Company
         and Executive. As a result of the uncertainty in the application of
         Section 4999 of the Code at the time of the initial determination by
         the Accounting Firm hereunder, it is possible that Gross-Up Payments
         which will not have been made by the Company should have been made (an
         "Underpayment"), consistent with the calculations required to be made
         hereunder. In the event that the Company exhausts its remedies pursuant
         to Paragraph (c) below and Executive hereafter is required to make a
         payment of any Excise Tax, the Accounting Firm shall determine the
         amount of the Underpayment that has occurred and any such Underpayment
         shall be paid by the Company to or for the benefit of Executive within
         five days of the Company's receipt of notice of such Underpayment.

                  (c) Executive shall notify the Company in writing of any claim
         by the Internal Revenue Service that, if successful, would require the
         payment by the Company of the Gross-Up Payment. Such notification shall
         be given as soon as practicable but no later than ten business days
         after Executive is informed in writing of such claim and shall apprise
         the Company of the nature of such claim and the date on which such
         claim is requested to be paid. Executive shall not pay such claim prior
         to the expiration of the thirty-day period following the date on which
         it gives such notice to the Company (or such shorter period ending on
         the date that any payment of taxes with respect to such claim is due).
         If the Company notifies Executive in writing prior to the expiration of
         such period that it desires to contest such claim, Executive shall:

                           (i) give the Company any information reasonably
                  requested by the Company relating to such claim;

                           (ii) take such action in connection with contesting
                  such claim as the Company shall reasonably request in writing
                  from time to time, including, without limitation, accepting
                  legal representation with respect to such claim by an attorney
                  reasonably selected by the Company;

                           (iii) cooperate with the Company in good faith in
                  order effectively to contest such claim; and

                           (iv) permit the Company to participate in any
                  proceedings relating to such claim; provided, however, that
                  the Company shall bear and pay directly all costs and expenses
                  (including additional interest and penalties) incurred in
                  connection with such contest and shall indemnify and hold
                  Executive harmless, on an after-tax basis, for any Excise Tax
                  and other taxes (including interest and penalties with respect
                  thereto) imposed as a result of such representation and
                  payment of costs and expenses. Without limitation on the
                  foregoing provisions of this Paragraph (c), the Company shall
                  control all proceedings taken in connection with such contest
                  and, at its sole option, may pursue or forgo any and all



   3

                  administrative appeals, proceedings, hearings and conferences
                  with the taxing authority in respect of such claim and may, at
                  its sole option, either direct Executive or pay the tax
                  claimed and sue for a refund or contest the claim in a
                  permissible manner, and Executive agrees to prosecute such
                  contest to a determination before any administrative tribunal,
                  in a court of initial jurisdiction and in one or more
                  appellate courts as the Company shall determine; provided,
                  however, that if the Company directs Executive to pay such
                  claim and sue for a refund, the Company shall advance the
                  amount of such payment to Executive on an interest-free basis
                  and shall indemnify and hold Executive harmless, on an
                  after-tax basis, from any Excise Tax and other taxes
                  (including interest or penalties with respect thereto) imposed
                  with respect to such advance or with respect to any imputed
                  income with respect to such advance and further provided that
                  an extension of the statute of limitations relating to payment
                  of taxes for the taxable year of Executive with respect to
                  which such contested amount is claimed to be due is limited
                  solely to such contested amount. Furthermore, the Company's
                  control of the contest shall be limited to issues with respect
                  to which a Gross-Up Payment would be payable hereunder and
                  Executive shall be entitled to settle or contest, as the case
                  may be, any other issue raised by the Internal Revenue Service
                  or any other taxing authority.

                  (d) If, after the receipt by Executive of an amount advanced
         by the Company pursuant to Paragraph (c), Executive becomes entitled to
         receive any refund with respect to such claim, Executive shall (subject
         to the Company's complying with the requirements of Paragraph (c))
         promptly pay to the Company the amount of such refund (together with
         any interest paid or credited thereon after taxes applicable thereto).
         If, after the receipt of Executive of an amount advanced by the Company
         pursuant to Paragraph 3, a determination is made that Executive shall
         not be entitled to any refund with respect to such claim and the
         Company does not notify Executive in writing of its intent to contest
         such denial of refund prior to the expiration of thirty days after such
         determination, then such advance shall be forgiven and shall not be
         required to be repaid and the amount of such advance shall offset, to
         the extent thereof, the amount of Gross-Up Payment required to be paid.

         2. SUCCESSOR AGREEMENT. The Company will require any successor (whether
direct or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform if no succession had taken
place.

         3. ARBITRATION. The parties agree to resolve any claim or controversy
arising out of or relating to this Agreement by binding arbitration under the
Federal Arbitration Act before one arbitrator in Denver, Colorado, administered
by the American Arbitration Association under its Commercial Arbitration Rules,
and judgment on the award rendered by the arbitrator may be entered in any court
having jurisdiction thereof. The Company shall pay all fees and expenses of the
arbitrator and all the costs and expenses (including, without limitation,
attorneys' fees) of Executive incurred in asserting any claims or rights under
this Agreement.

                  REGARD TO CONFLICTS OF LAW PRINCIPLES.

                  (b) EACH PARTY HERETO HEREBY IRREVOCABLY SUBMITS TO THE
                  EXCLUSIVE JURISDICTION OF THE STATE AND FEDERAL COURTS IN
                  DENVER COUNTY, COLORADO, FOR THE PURPOSES OF ANY PROCEEDING
                  ARISING OUT OF THIS AGREEMENT.

         5. ENTIRE AGREEMENT. This Agreement is an integration of the parties'
agreement and no agreement or representatives, oral or otherwise, express or
implied, with respect to the subject matter hereof have been made by either
party which are not set forth expressly in this Agreement.

Executive's employment, whether before, on or after a Change of Control.

         IN WITNESS WHEREOF, the parties have executed this Agreement effective
for all purposes as of the date first provided above.
