                             STOCK OPTION AGREEMENT

     THIS STOCK OPTION AGREEMENT (the "Agreement") is made and entered into as
of the 25th day of January, 2001 by and between Double Eagle Petroleum And
Mining Co., a Wyoming corporation (the "Company"), and Stephen H. Hollis (the
"Optionee").

                                   WITNESSETH:

     WHEREAS, the Company agreed to issue to Optionee an option to purchase
shares of the $.01 par value common stock of the Company ("Common Stock"), said
option to be for the number of shares, at the price per share and on the terms
set forth in this Agreement; and

     WHEREAS, the Optionee desires to receive an option on the terms and
conditions set forth in this Agreement.

     NOW, THEREFORE, the parties agree as follows:

     1. Grant Of Option. The Company hereby grants to the Optionee the right and
option (the "Option") to purchase all or any part of an aggregate of 20,000
shares of the authorized and unissued $.10 par value common stock of the Company
(the "Option Shares") pursuant to the terms and conditions set forth in this
Agreement.

     2. Option Price. At any time when shares are to be purchased pursuant to
the Option, the purchase price for each Option Share shall be $4.531 (the
"Option Price"), subject to adjustment as provided in this Agreement.

     3. Exercise Period. The period for the exercise of the Option shall
commence on the date of this Agreement and shall terminate at 5:00 p.m., Denver,
Colorado time on January 25, 2004 unless terminated earlier as provided in this
Agreement. Notwithstanding the foregoing, to the extent not earlier terminated,
the Option shall terminate three months after the termination of the Optionee's
employment with the Company.

     4. Exercise Of Option.

          (a) The Option may be exercised in whole or in part by delivering to
     the Treasurer of the Company (i) a Notice And Agreement Of Exercise Of
     Option, substantially in the form attached hereto as Exhibit A, specifying
     the number of Option Shares with respect to which the Option is exercised,
     and (ii) full payment of the Option Price for such shares. Payment shall be
     made by certified check or cleared funds. The Option may not be exercised
     in part unless the purchase price for the Option Shares purchased is at
     least $1,000 or unless the entire remaining portion of the Option is being
     exercised.

          (b) Promptly upon receipt of the Notice And Agreement Of Exercise Of
     Option together with the full payment of the Option Price, the Company
     shall deliver to the Optionee a properly executed certificate or
     certificates representing the Option Shares being purchased.

     5. Withholding Taxes. The Company may take such steps as it deems necessary
or appropriate for the withholding of any taxes which the Company is required by
any law or regulation or any governmental authority, whether federal, state or
local, domestic or foreign, to withhold in connection with the Option including,
but not limited to, the withholding of all or any portion of any payment owed by
the Company to the Optionee or the withholding of issuance of Option Shares to
be issued upon the exercise of the Option.

     6. Securities Laws Requirements. No Option Shares shall be issued unless
and until, in the opinion of the Company, there has been full compliance with,
or an exemption from, any applicable registration requirements of the Securities
Act of 1933, as amended (the "1933 Act"), any applicable listing requirements of
any securities exchange on which stock of the same class has been listed, and
any other requirements of law or any regulatory bodies having jurisdiction over
such issuance and delivery, or applicable exemptions are available and have been
complied with. Pursuant to the terms of the Notice And Agreement Of Exercise Of
Option (Exhibit A) that shall be delivered to the Company upon each exercise of
the Option, the Optionee shall acknowledge, represent, warrant and agree as
follows:

          (a) Optionee is acquiring the Option Shares for investment purposes
     only and the Option Shares that Optionee is acquiring will be held by
     Optionee without sale, transfer or other disposition for an indefinite
     period unless the transfer of those securities is subsequently registered
     under the federal securities laws or unless exemptions from registration
     are available;

          (b) Optionee's overall commitment to investments that are not readily
     marketable is not disproportionate to Optionee's net worth and Optionee's
     investment in the Option Shares will not cause such overall commitments to
     become excessive;

          (c) Optionee's financial condition is such that Optionee is under no
     present or contemplated future need to dispose of any portion of the Option
     Shares to satisfy any existing or contemplated undertaking, need or
     indebtedness;

          (d) Optionee has sufficient knowledge and experience in business and
     financial matters to evaluate, and Optionee has evaluated, the merits and
     risks of an investment in the Option Shares;

          (e) The address set forth on the signature page to this Agreement is
     Optionee's true and correct residence, and Optionee has no present
     intention of becoming a resident of any other state or jurisdiction;

          (f) Optionee confirms that all documents, records and books pertaining
     to an investment in the Option and the Option Shares that have been
     requested by Optionee have been made available or delivered to Optionee.
     Without limiting the foregoing, Optionee has received and reviewed the
     Company's periodic reports filed with the Securities And Exchange
     Commission and Optionee has had the opportunity to discuss the acquisition
     of the Option and the Option Shares with the Company, and Optionee has
     obtained or been given access to all information concerning the Company
     that Optionee has requested;

          (g) Optionee has had the opportunity to ask questions of, and receive
     the answers from, the Company concerning the terms of the investment in the
     Option Shares and to receive additional information necessary to verify the
     accuracy of the information delivered to Optionee, to the extent that the
     Company possesses such information or can acquire it without unreasonable
     effort or expense;

          (h) Optionee understands that the Options have not, and the Option
     Shares issuable upon exercise of the Options will not be, registered under
     the 1933 Act or any state securities laws in reliance on an exemption for
     private offerings, and no federal or state agency has made any finding or
     determination as to the fairness of this investment or any recommendation
     or endorsement of the sale of the Option Shares;

                                       2
<PAGE>

          (i) The Option Shares that Optionee is acquiring will be solely for
     Optionee's own account, for investment, and are not being purchased with a
     view to or for the resale, distribution, subdivision or fractionalization
     thereof. Optionee has no agreement or arrangement for any such resale,
     distribution, subdivision or fractionalization thereof;

          (j) Optionee acknowledges and is aware of the following:

               (i) The Company has a history of losses. The Option Shares
          constitute a speculative investment and involve a high degree of risk
          of loss by Optionee of Optionee's total investment in the Option
          Shares.

               (ii) There are substantial restrictions on the transferability of
          the Option Shares. The Option is not transferable except by will or
          the laws of descent and distribution, and any attempt to do so shall
          void the Option. The Option Shares cannot be transferred, pledged,
          hypothecated, sold or otherwise disposed of unless they are registered
          under the 1933 Act or an exemption from such registration is available
          and established to the satisfaction of the Company; investors in the
          Company have no rights to require that the Option Shares be
          registered; there is no right of presentment of the Option Shares and
          there is no obligation by the Company to repurchase any of the Option
          Shares; and, accordingly, Optionee may have to hold the Option Shares
          indefinitely and it may not be possible for Optionee to liquidate
          Optionee's investment in the Company.

               (iii) Unless the issuance of the Option Shares is registered,
          each certificate issued representing the Option Shares shall be
          imprinted with a legend that sets forth a description of the
          restrictions on transferability of those securities, which legend will
          read substantially as follows:

                    "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
               NOT BEEN REGISTERED WITH THE UNITED STATES SECURITIES AND
               EXCHANGE COMMISSION UNDER THE U.S. SECURITIES ACT OF 1933,
               AS AMENDED (THE "1933 ACT"), AND ARE `RESTRICTED SECURITIES'
               AS THAT TERM IS DEFINED IN RULE 144 UNDER THE 1933 ACT. THE
               SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD OR OTHERWISE
               TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION
               STATEMENT UNDER THE 1933 ACT, OR PURSUANT TO AN EXEMPTION
               FROM REGISTRATION UNDER THE 1933 ACT."

          The restrictions described in this Section 6 or notice thereof may be
placed on the certificates representing the Option Shares purchased pursuant to
the Option, and the Company may refuse to issue the certificates or to transfer
the shares on its books unless it is satisfied that no violation of such
restrictions will occur.

     7. Adjustment By Stock Split, Stock Dividend, Etc. If at any time the
Company increases or decreases the number of its outstanding shares of common
stock, or changes in any way the rights and privileges of such shares, by means
of the payment of a stock dividend or the making of any other distribution on
such shares payable in its common stock, or through a stock split or subdivision
of shares, or a consolidation or combination of shares, or through a
reclassification or recapitalization involving its common stock, the numbers,

                                        3
<PAGE>

rights and privileges of the shares of common stock included in the Option shall
be increased, decreased or changed in like manner as if such shares had been
issued and outstanding, fully paid and nonassessable at the time of such
occurrence and the Option Price shall be correspondingly decreased, increased or
otherwise changed. Whenever the number or kind of shares comprising the Option
Shares or the Option Price is adjusted, the Company shall promptly give written
notice and a certificate of the Chief Financial Officer or President of the
Company to each holder of record of the outstanding Options, stating that such
an adjustment has been effected and setting forth the number and kind of shares
purchasable and the amount of the then-current Option Price, and stating in
reasonable detail the facts requiring such adjustment and the calculation of
such adjustment.

     8. Reorganization And Reclassification. In case of any capital
reorganization or any reclassification of the capital stock of the Company while
the Options remain outstanding, the holder of the Options shall thereafter be
entitled to purchase pursuant to the Options (in lieu of the kind and number of
shares of Common Stock comprising Option Shares that such holder would have been
entitled to purchase or acquire immediately before such reorganization or
reclassification) the kind and number of shares of stock of any class or classes
or other securities or property for or into which such shares of Common Stock
would have been exchanged, converted, or reclassified if the Option Shares had
been purchased immediately before such reorganization or reclassification. In
case of any such reorganization or reclassification, appropriate provision (as
determined by resolutions of the Board of Directors of the Company) shall be
made with respect to the rights and interest thereafter of the holder of the
Options, to the end that all the provisions of this Option Agreement (including
adjustment provisions) shall thereafter be applicable, as nearly as reasonably
practicable, in relation to such stock or other securities or property.

     9. Registration Rights. Optionee shall have no registration rights unless
otherwise agreed by the Company.

     10. Common Stock To Be Received Upon Exercise. Optionee understands that
(a) the Company is under no obligation to register the issuance of the Option
Shares, and (b) in the absence of any such registration, the Option Shares
cannot be sold unless they are sold pursuant to an exemption from registration
under the 1933 Act. Optionee also understands that with respect to Rule 144,
routine sales of securities made in reliance upon such Rule can be made only in
limited amounts in accordance with the terms and conditions of the Rule, and
that in cases in which the Rule is inapplicable, compliance with either
Regulation A or another disclosure exemption under the 1933 Act will be
required. Thus, the Option Shares will have to be held indefinitely in the
absence of registration under the 1933 Act or an exemption from registration.

          Furthermore, the Optionee fully understands that issuance of the
Option Shares will not be registered under the 1933 Act and that, because the
issuance of the Option Shares will not be registered, the Option Shares will be
issued in reliance upon an exemption which is available only if Optionee
acquires such shares for investment and not with a view to distribution.
Optionee is familiar with the phrase "acquired for investment and not with a
view to distribution" as it relates to the 1933 Act and the special meaning
given to such term in various releases of the Securities And Exchange
Commission.

     11. Privilege Of Ownership. Optionee shall not have any of the rights of a
stockholder with respect to the shares covered by the Option except to the
extent that one or more certificates for such shares shall be delivered to him
upon exercise of the Option.

     12. Relationship To Employment. Nothing contained in this Agreement (i)
shall confer upon the Optionee any right with respect to continuance of
Optionee's employment by, or affiliation with, or relationship to, the Company,
or (ii) shall interfere in any way with the right of the Company at any time to
terminate the Optionee's employment by, position or affiliation with, or
relationship to, the Company.

                   NOTICE AND AGREEMENT OF EXERCISE OF OPTION

     The undersigned Optionee hereby exercises my Double Eagle Petroleum And
Mining Co. Stock Option dated as of January 25, 2001 as to ________ shares of

in the form of ___________________.

     Enclosed is the payment specified in Paragraph 4 of my Option Agreement.

     The undersigned Optionee understands that no Option Shares will be issued
unless and until, in the opinion of the Company, there has been full compliance
with, or an exemption from, any applicable registration requirements of the
Securities Act of 1933, as amended (the "1933 Act"), any applicable listing
requirements of any securities exchange on which stock of the same class is then
listed, and any other requirements of law or any regulatory bodies having
jurisdiction over such issuance and delivery. The undersigned Optionee hereby
acknowledges, represents, warrants and agrees, to and with the Company as
follows:

     (a) Optionee is acquiring the Option Shares for investment purposes only
and the Option Shares that Optionee is acquiring will be held by Optionee
without sale, transfer or other disposition for an indefinite period unless the
transfer of those securities is subsequently registered under the federal
securities laws or unless exemptions from registration are available;

     (b) Optionee's overall commitment to investments that are not readily
marketable is not disproportionate to Optionee's net worth and Optionee's
investment in the Option Shares will not cause such overall commitments to
become excessive;

     (c) Optionee's financial condition is such that Optionee is under no
present or contemplated future need to dispose of any portion of the Option
Shares to satisfy any existing or contemplated undertaking, need or
indebtedness;

     (d) Optionee has sufficient knowledge and experience in business and
financial matters to evaluate, and Optionee has evaluated, the merits and risks
of an investment in the Option Shares;

     (e) The address set forth on the signature page of this Notice is
Optionee's true and correct residence, and Optionee has no present intention of
becoming a resident of any other state or jurisdiction;

     (f) Optionee confirms that all documents, records and books pertaining to
an investment in the Option Shares that have been requested by Optionee have
been made available or delivered to Optionee. Without limiting the foregoing,
Optionee has received and reviewed the Company's periodic reports filed with the
Securities And Exchange Commission and Optionee has had the opportunity to
discuss the acquisition of the Option and the Option Shares with the Company,
and Optionee has obtained or been given access to all information concerning the
Company that Optionee has requested;

<PAGE>

     (g) Optionee has had the opportunity to ask questions of, and receive the
answers from, the Company concerning the terms of the investment in the Option
Shares and to receive additional information necessary to verify the accuracy of
the information delivered to Optionee, to the extent that the Company possesses
such information or can acquire it without unreasonable effort or expense;

     (h) Optionee understands that the Options have not, and the Option Shares
issuable upon exercise of the Options will not be, registered under the 1933 Act

and no federal or state agency has made any finding or determination as to the
fairness of this investment or any recommendation or endorsement of the sale of
the Option Shares;

     (i) The Option Shares that Optionee is acquiring will be solely for
Optionee's own account, for investment, and are not being purchased with a view
to or for the resale, distribution, subdivision or fractionalization thereof.
Optionee has no agreement or arrangement for any such resale, distribution,
subdivision or fractionalization thereof;

     (j) Optionee acknowledges and is aware of the following:

          (i) The Company has a history of losses. The Option Shares constitute
     a speculative investment and involve a high degree of risk of loss by
     Optionee of Optionee's total investment in the Option Shares.

          (ii) There are substantial restrictions on the transferability of the
     Option Shares. The Option Shares cannot be transferred, pledged,
     hypothecated, sold or otherwise disposed of unless they are registered
     under the 1933 Act or an exemption from such registration is available and
     established to the satisfaction of the Company; investors in the Company
     have no rights to require that the Option Shares be registered; there is no
     right of presentment of the Option Shares and there is no obligation by the
     Company to repurchase any of the Option Shares; and, accordingly, Optionee
     may have to hold the Option Shares indefinitely and it may not be possible
     for Optionee to liquidate Optionee's investment in the Company.

          (iii) Unless the issuance of the Option Shares is registered, each
     certificate issued representing the Option Shares shall be imprinted with a
     legend that sets forth a description of the restrictions on transferability
     of those securities, which legend will read substantially as follows:

          "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED WITH THE UNITED STATES SECURITIES AND EXCHANGE
          COMMISSION UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE
