Nevada Company ("Company") and PETROHAWK ENERGY, LLC, a Delaware limited liability company ("Petrohawk"). 

RECITALS  

        WHEREAS, pursuant to that certain Securities Purchase Agreement by and between Company and Petrohawk executed on December 12, 2003 (the "Purchase
Agreement"), Petrohawk will receive the number of shares of Common Stock, Note and Warrants as set forth on Schedule 1. 

        WHEREAS,
as a condition to the Purchase Agreement, Company has agreed to grant to the Stockholders (defined hereafter) certain registration rights with respect to its Registrable
Securities (defined hereafter). 

        WHEREAS,
all the terms used but not defined in this Agreement shall have the meaning ascribed to them in the Purchase Agreement. 

        NOW,
THEREFORE, in consideration of the mutual promises contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows: 

        Section 1.    Definitions.    

        For
purposes of this Agreement, the following terms shall have the respective meanings assigned to them in this Section 1 or in the recitals above or the subsections referred to
below. 

        "Registrable
Securities" shall mean (i) the shares of Common Stock issued to the Stockholder(s) pursuant to the Purchase Agreement (which, for purposes hereof, shall mean the
Common Stock Shares, the Warrant Shares and the Conversion Shares as defined in the Purchase Agreement) and (ii) any securities issued or issuable with respect to the shares described in
clause (i) above by way of a stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or other reorganization provided, however, that
as to any particular Registrable Securities, such security shall cease to be Registrable Securities when (i) a registration statement with respect to the sale of such security shall have become
effective under the Act and such security shall have been disposed of in accordance with such registration statement or (ii) such securities shall have been sold to the public pursuant to
Rule 144 (or any successor provision) under the Act. 

        "Stockholders(s)"
shall mean Petrohawk and all Affiliates of Petrohawk that become holders of Registrable Securities. 

        Section 2.    Independent Registration Rights.    

        2.1   The
Company hereby grants to Stockholders separate rights to require the Company to use its best efforts to cause registration and sale in a public offering of all or a
portion of Stockholders' Registrable Securities in accordance with this Section 2; provided, however, the Company shall not have any obligation to effect more than a total of two
(2) effective registrations pursuant to this Section 2 or effect more than one (1) in any twelve (12) month period. If the Company shall have received a written request
submitted by Stockholder(s) owning at least a majority of the Registrable Securities outstanding at the time of such request (the "Requisite Holders") that such Stockholder(s) desires/desire to sell
Registrable Securities and specifying the number of Registrable Securities 

D-1

 

proposed
to be sold (for the purposes of this Section 2, "Shares" and which shall in no event be less than 500,000 Shares) and the proposed plan for distribution of the Shares, Company will
thereafter: 

        2.1.1 Give
prompt (but in any event within fifteen (15) days after the receipt of the Requisite Holder(s)' notice) notice to all other Stockholders of such notice and
of such other Stockholders' rights to have their Registrable Securities included in such registration. 

        2.1.2 Upon
the request of any such Stockholder made within fifteen (15) days after the receipt by such Stockholder of any such notice given pursuant to subsection
2.1.1 (which request shall specify the Registrable Securities intended to be disposed of by such Stockholder and the intended method or methods of disposition thereof), the Company will use its best
efforts to effect the registration of all Shares which the Company has been so requested to register pursuant to this subsection 2.1. 

        2.1.3 Prepare
and file as soon as practicable, but in no event later than thirty (30) days from Company's receipt of the last Stockholder's request to have such
Stockholder's Registrable Securities included in such registration within the time period specified in Section 2.1.2, a registration statement under the Securities Act of 1933, as amended (the
"Securities Act") ("Registration Statement") with the Securities Exchange Commission ("Commission") on Form S-1 (or Form S-2 or Form S-3, if
Company is entitled to use such forms, or similar forms available for use by small business issuers) and use its best efforts to cause such Registration Statement to become effective in order that the
Stockholders may sell the Shares in accordance with the proposed plan of distribution. 

        2.1.4 Prepare
and file with the Commission such amendment and supplements to such Registration Statement and prospectus used in connection therewith including any
preliminary prospectus or supplemental or amended prospectus (the "Prospectus") as may be necessary to keep such Registration Statement continuously effective and to comply with the provisions of the
Securities Act with respect to the offer of the Shares during the period required for distribution of the Shares, which period shall not be in excess of the earlier of (i) nine months from the
effective date of such Registration Statement, and (ii) the distribution of all Shares covered by such Registration Statement. 

        2.1.5 Furnish
to each Stockholder such number of copies of the Prospectus (including any preliminary prospectus or supplemental or amended prospectus) as such Stockholder
may reasonably request in order to facilitate the sale and distribution of the Shares. 

        2.1.6 Notwithstanding
the foregoing, if the Company shall furnish to the each Stockholder a certificate signed by the President of the Company stating that, in the good
faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its stockholders for such registration statement to be filed and it is therefore essential
to defer the filing of such registration statement, the Company shall have the right to defer such filing for a period of not more than sixty (60) days after receipt of the request of the
Stockholder; provided, however, that the Company may not utilize this right with respect to a request
under Section 2 more than once in any twelve (12) month period. 

        2.2   The
right of each Stockholder to register Shares pursuant to the provisions of this Section 2 shall be subject to the condition that if a request for registration
is made within sixty (60) days prior to the conclusion of Company's then current fiscal year, Company shall have the right to delay the filing of the Registration Statement for such period of
time until Company files its audited financial statements for such fiscal year. 

        2.3   If
the Requisite Holder(s) intend/intends to distribute the Registrable Securities covered by the notice pursuant to section 2.1 by means of an underwriting, the
Requisite Holder(s) shall so advise the Company as a part of the notice made pursuant to section 2.1 and provide the name of the 

D-2

 

managing
underwriter or underwriters that the Requisite Holder(s) proposes/propose to employ in connection with the public offering proposed to be made pursuant to the registration requested. If the
managing underwriter of such underwritten offering shall inform the Company and the Stockholders requesting that their Shares be registered pursuant to this Section 2 by letter of its belief
that the amount of Shares requested to be included in such registration exceeds the amount which can be sold in (or during the time of) such offering within a price range acceptable to the Requisite
Holders, then the Company will include in such registration such amount of Shares which the Company is so advised can be sold in (or during the time of) such offering pro
rata on the basis of the amount of such Shares so proposed to be sold and so requested to be included by such parties. 

        2.4   A
registration shall not be deemed to have been effected (i) unless it has become effective and remained effective for the period specified in subsection 2.1.4,
(ii) if, after it has become effective, such registration is terminated by a stop order, injunction or other order of the Commission or other governmental agency or court, or (iii) if
the conditions to closing specified in any purchase agreement or underwriting agreement entered into in connection with such registration are not satisfied for any reason, other than as a result of
the voluntary termination of such offering by the Requisite Holders or any failure by the Requisite Holders to satisfy or perform the conditions or covenants on their part to be satisfied or
performed. 

        Section 3.    Piggy-Back Registration Rights.    

        3.1   If
Company proposes to file, on its behalf, a Registration Statement under the Securities Act on Form S-1, S-2 or S-3 or
similar forms available for use by small business issuers, other than pursuant to Section 2 of this Agreement or in connection with a dividend reinvestment, employee stock purchase, option or
similar plan or in connection with a merger, consolidation or reorganization, Company shall give written notice to Stockholder at least ten (10) days before the filing with the Commission of
such Registration Statement. Such notice shall offer to include in such filing all or a portion of the Registrable Securities owned by Stockholder. If Stockholder desires to include all or a portion
of its Registrable Securities in such Registration Statement, it shall give written notice to Company within three (3) days after the date of mailing of such offer specifying the amount of
Registrable Securities to be registered (for the purpose of this Section 3, "Shares"). Company shall thereupon include in such filing the Shares, subject to priorities in registration set forth
in this Agreement, and subject to its right to withdraw such filing, and shall use its best efforts to affect registration under the Securities Act of the Shares. 

        3.2   The
right of Stockholder to have the Shares included in any Registration Statement in accordance with the provisions of this Section 3 shall be subject to the
following conditions: 

        3.2.1 Company
shall have the right to require that Stockholder agree to refrain from offering or selling any shares of Common Stock that it owns which are not included in
any such Registration Statement in accordance with this Section 3 for any reasonable time period specified, not to exceed ninety (90) days, by any managing underwriter of the offering to
which such Registration Statement relates. 

        3.2.2 If
(i) a registration pursuant to this Section 3 involves an underwritten offering of the securities being registered to be distributed (on a firm
commitment basis) by or through one or more underwriters of recognized standing under underwriting terms appropriate for such a transaction and (ii) the managing underwriter of such
underwritten offering shall inform the Company and Stockholder who has requested that its Shares be registered pursuant to this Section 3 by letter of its belief that the amount of Shares
requested to be included in such registration exceeds the amount which can be sold in (or during the time of) such offering within a price range acceptable to the Company or a majority of such
requesting holders, then the Company will include in such registration such amount of securities which the Company is so advised can be sold in (or during the time of) such offering as follows:  first,
the securities being 

D-3

 

offered
by the Company for its own account; and second such Shares of the Stockholders which are requested to be included in such registration  pro rata on the
basis of the amount of such Shares so proposed to be sold and so requested to be included by such Stockholders. 

        3.2.3 Company
shall furnish Stockholder with such number of copies of the Prospectus as Stockholder may reasonably request in order to facilitate the sale and distribution
of its shares. 

        3.3   Notwithstanding
the foregoing, Company in its sole discretion may determine not to file the Registration Statement or proceed with the offering as to which the notice
specified herein is given without liability to Stockholder. 

        Section 4.    Participation in Underwritten Registrations.    Stockholder may not participate in any
registration hereunder which relates to an underwritten offering unless Stockholder (a) agrees to sell such holder's securities on the basis provided in any underwriting arrangements approved
by the holders of at least a majority of the Registrable Securities to be included in such registration, or by a Person appointed by such holders to act on their behalf to approve such arrangements,
and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting
arrangements. 

        Section 5.    Exclusive Registration Rights and Transfer.    

        The
rights of Stockholder under this Agreement may upon notice to the Company be transferred to its respective Affiliates in combination with a transfer of shares to such Affiliates.
However, the rights of Stockholder under this Agreement may not be assigned or transferred to a non-Affiliate without the Company's written consent. Except as provided in this
Section 5, the rights granted under this Agreement are granted specifically to and for the benefit of Stockholder and shall not pass to any transferee of Registrable Securities. From and after
the date of this Agreement, the Company will not, without the prior written consent of Stockholders holding at least a majority of the Registrable Securities then outstanding, enter into any agreement
with respect to its securities which is inconsistent with or violates the rights granted to the Stockholders in this Agreement. The foregoing shall not restrict or prevent the Company from entering
into any other agreement with any party pertaining to the registration by the Company of such party's Common Stock. Except as set forth in Schedule 2 attached hereto, the Company represents and
warrants to Stockholders that, as of the date hereof, the Company is not a party to any agreement, other than this Agreement, pertaining to the registration by the Company of Common Stock. 

        Section 6.    Expenses.    Company will bear all the expenses in connection with any Registration Statement
under this Agreement, other than transfer taxes payable on the sale of such shares, the fees and expenses of counsel to Stockholder and fees and commissions of brokers, dealers and underwriters. 

        Section 7.    Recall of Prospectuses, etc.    With respect to a Registration Statement or amendment thereto
filed pursuant to this Agreement, if, at any time, Company notifies Stockholder that an amendment or supplement to such Registration Statement or amendment to the Prospectus included therein is
necessary or appropriate, Stockholder will forthwith cease selling and distributing shares thereunder and will forthwith redeliver to Company all copies of such Registration Statement and Prospectuses
then in its possession or under its control. Company will use its best efforts to cause any such amendment or supplement to become effective as soon as practicable and will furnish Stockholder with a
reasonable number of copies of such amended or supplemented prospectus (and the period during which Company is required to use its best efforts to maintain such Registration Statement in effect
pursuant to this Agreement will be increased by the period from the date on which Stockholder ceased selling and distributing shares thereunder to the date on which such amendment or supplement
becomes effective). 

        Section 8.    Cooperation with Existing Stockholders.    Company shall be entitled to require Stockholder to
cooperate with Company in connection with a registration of Registrable Securities 

D-4

 

pursuant
to this Agreement and furnish (i) such information as may be required by Company or the Commission in connection therewith and (ii) such representations, undertakings and
agreements as may be required by the Commission in connection therewith. 

        Section 9.    Registration Procedures.    Upon the receipt of a request for registration of any Registrable
Securities pursuant to Section 2 or Section 3 of this Agreement, Company will use its best efforts to
effect the registration of the Registrable Securities in accordance with the intended method of disposition thereof, and pursuant thereto Company will as expeditiously as possible: 

        9.1.1 Prepare
and file with the Commission a registration statement on an appropriate form under the Securities Act and use its best efforts to cause such registration
statement to become effective; provided, that before filing a registration statement or prospectus or any amendments or supplements thereto, including documents incorporated by reference after the
initial filing of any registration statement, Company will promptly furnish to the holders of Registrable Securities to be registered and sold pursuant to this Agreement (the "Registered Holders") and
the underwriters, if any, copies of all such documents proposed to be filed, which documents will be subject to the review of the Registered Holders and the underwriters, and Company will not file any
registration statement or amendment thereto, or any prospectus or any supplement thereto (including such documents incorporated by reference) to which the Registered Holders or the underwriters, if
any, shall reasonably object in light of the requirements of the Securities Act and any other applicable laws and regulations. 

        9.1.2 Prepare
and file with the Commission such amendments and post-effective amendments to a registration statement as may be necessary to keep such

prospectus to be supplemented by any required prospectus supplement and, as so supplemented, to be filed pursuant to Rule 424(b) (or any successor provision) under the Securities Act; and

methods of disposition set forth in such registration statement or supplement to such prospectus. 

        9.1.3 Notify
the Registered Holders and the managing underwriters, if any, promptly, and (if requested by any such person) confirm such advice in writing, (i) when a
prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to a registration statement or any post-effective amendment, when the same
has become effective, (ii) of any request by the Commission for amendments or supplements to a registration statement or related prospectus or for additional information, (iii) of the
issuance by the Commission of any stop order suspending the effectiveness of a registration statement or the initiation of any proceeding for that purpose, (iv) if at any time the

qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation of any proceeding for such purpose, (vi) of the happening of any event which requires the
making of any changes in a registration statement or related prospectus so that such documents will not contain any untrue statement of a material fact or omit to state any material fact required to
be stated therein or necessary to make the statements therein not misleading and (vii) of Company's reasonable determination that a post-effective amendment to a registration
statement would be appropriate or that there exist circumstances not yet disclosed to the public which make further sales under such registration statement inadvisable pending such disclosures and
post-effective amendment. 

D-5

 

        9.1.4 Make
reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of a registration statement, or the lifting of any suspension of the

underwriters and with respect to any other terms of the underwritten (or best efforts underwritten) offering of the Registrable Securities to be sold in such offering; make all required filings of
such prospectus supplement or post-effective amendment as soon as notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and
supplement or make amendments to any registration statement if requested by the Registered Holders or any underwriter of such Registrable Securities. 

        9.1.6 Furnish

the underwriters, if any, in connection with the offer and sale of the Registrable Securities covered by such prospectus or any amendment or supplement thereto. 

        9.1.8 Prior
to any public offering of Registrable Securities, register or qualify or cooperate with the Registered Holders, the underwriters, if any, and respective counsel
in connection with the registration or qualification of such Registrable Securities for offer and sale under the securities or Blue Sky laws of such jurisdictions as the Registered Holders or an
underwriter reasonably requests in writing; keep each such registration or qualification effective during the period such registration statement is required to be kept effective and do any and all
other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Registrable Securities covered by the applicable registration statement;  provided, however, that
Company will not be required in connection therewith or as a condition thereto to qualify generally to do business or subject

        9.1.9 Upon
the occurrence of any event contemplated by subsection 9.1.3 (ii)—(vii) above, prepare, to the extent required, a supplement or
post-effective amendment to the
applicable registration statement or related prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchaser of the

misleading.

        9.1.11 Make

attorney or accountant retained by the Registered Holders or such underwriter, all financial and other records, pertinent corporate documents and properties of Company, and cause Company's officers,
directors and employees to supply all information reasonably requested by any such representative, underwriter, attorney or accountant in connection with such registration; provided that any records,

such settlement is effected without prior written consent of the indemnifying Stockholder, or its representative; but in all cases only if, and to the extent that any such loss, claim, damage,
liability or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission therein made in reliance upon and in conformity with written
information furnished to Company by the indemnifying Stockholder, or its affiliates or representatives specifically for use in the preparation thereof. Notwithstanding the foregoing, the 

D-8

 

amount
of the indemnity provided by Stockholder pursuant to this Section 10 shall not exceed the net proceeds received by Stockholder in such related registration and sale. 

        10.3 Promptly
after receipt by a party entitled to indemnification under subsection 10.1 or 10.2 hereof of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party under either of such subsections, notify the indemnifying party in writing of the commencement thereof. In case any
such action is brought against the indemnified party and it shall so notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the
extent that it so chooses, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party that it so chooses, such
indemnifying party shall not be liable for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof, provided, however, that if the
indemnifying party fails to take reasonable steps necessary to diligently defend such claim within twenty (20) days after receiving notice from the indemnified party that the indemnified party
believes the indemnifying party has failed to take such steps, the indemnified party may assume its own defense and the indemnifying party shall be liable for any expenses therefore. The indemnity
agreements in this Section 10 shall be in addition to any liabilities which the indemnifying parties may have pursuant to law. 

        10.4 If
the indemnification provided for in this Section 10 from the indemnifying party is unavailable to an indemnified party hereunder in respect of any losses,
claims, damages, liabilities or expenses referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified
parties in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of such
indemnifying party and indemnified parties shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or indemnified parties, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred
to above shall be deemed to include, subject to the limitations set forth in Section 10 hereof, any legal or other fees or expenses reasonably incurred by such party in connection with any
investigation or proceeding. 

        The
parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 10 were determined by pro rata allocation or by any other method of
allocation which does not take into account the equitable considerations referred to in the immediately preceding paragraph. No Person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 

        Section 11.    Sales under Rule 144.    With a view to making available to Stockholder the benefits of
Rule 144 promulgated under the Securities Act and any other similar rule or regulation of the Commission that may at any time permit Stockholder to sell the Registrable Securities without
registration, Company agrees to: 

        (a)   make
and keep public information available, as those terms are understood and defined in Rule 144 (or any successor provision); 

        (b)   file
with the Commission in a timely manner all reports and other documents required of Company under the Securities Act and the Exchange Act; 

D-9

 

        (c)   furnish
to Stockholder forthwith upon request (i) a written statement by Company that it has complied with the reporting requirements of Rule 144 (or any
successor provision), the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of Company and such other reports and documents so filed by Company
under the Securities Act and the Exchange Act and
(iii) such other information as may be reasonably requested by Stockholder in availing itself of any rule or regulation of the Commission which permits the selling of any such securities
without registration; and 

        (d)   after
any sale of Registrable Securities pursuant to Rule 144, to the extent allowed by law, to cause any restrictive legends to be removed and any transfer
restrictions to be rescinded with respect to such Registrable Securities. 

        Section 12.    Removal of Legend.    The Company agrees, to the extent allowed by law, to remove any legends on
certificates representing Registrable Securities describing transfer restrictions applicable to such securities upon the sale of such securities (i) pursuant to an effective Registration
Statement under the Securities Act or (ii) in accordance with the provisions of Rule 144 under the Securities Act. 

        Section 13.    Notices.    Any notice to be given by any party hereunder to any other shall be in writing,
mailed by certified or registered mail, return receipt requested, or via overnight delivery service and shall be addressed to the other parties at the addresses listed on the signature pages hereof.
Notice shall be deemed effective upon receipt or refusal. 

        Section 14.    Modification.    Notwithstanding anything to the contrary in this Agreement or otherwise, no
modification, amendment or waiver of any of the provisions of this Agreement shall be effective unless in writing and signed by the Company and the Stockholders holding not less than 75% of the
Registrable Securities then outstanding. Any such modification, amendment shall be binding on all holders of Registrable Securities and all persons who may thereafter acquire any Registrable
Securities. 

        Section 15.    Non-Waiver.    The failure to enforce at any time any of the provisions of this
Agreement, or to require at any time performance by any other party of any of the provisions hereof, shall in no way be construed to be a waiver of such provisions. 

        Section 16.    Partial Invalidity.    If any clause, sentence, paragraph, section or part of this Agreement
shall be deemed invalid, unenforceable or against public policy, the part which is invalid, unenforceable or contrary to public policy shall not affect, impair, invalidate or nullify the remainder of
this Agreement, but the invalidity, unenforceability or contrariness to public policy shall be confined only to the clause, sentence, paragraph, section or part of this Agreement so invalidated,
unenforceable or against public policy. 

        Section.
17.    Termination of Registration Right.    No Stockholder shall be entitled to exercise any right provided
for in this Agreement after the fifth anniversary of the Closing of the transactions contemplated by the Purchase Agreement (the "Termination Date"). Notwithstanding any other provision of this
Agreement to the contrary, the registration rights granted hereunder will terminate prior to the Termination Date as to any Stockholder upon the first day the Stockholder is able to sell
all of the Registrable Securities owned by such Holder under Rule 144 within any given three-month period. 

        Section 18.    Construction.    The language in all parts of this Agreement shall in all cases be construed
simply, according to its fair meaning, and shall not be construed strictly for or against either of the parties hereto. 

        Section 19.    Governing Law.    This Agreement shall be governed and construed according to the laws of the
State of Oklahoma, without regard to its conflicts of law principles.

        Section 20.    Counterparts.    This Agreement may be executed in one or more counterparts, each of which shall
constitute an original and all of which together shall constitute but one and the same instrument. 

        Section 21.    Successors and Assigns.    This Agreement shall be binding upon and inure to the benefit of and
be enforceable by the parties hereto and their respective successors and permitted assigns. 

        Section 22.    Specific Performance.    The parties agree that, to the extent permitted by law, (i) the
obligations imposed on them in this Agreement are special, unique and of an extraordinary character, and that in the event of a breach by any such party damages would not be an adequate remedy and
(ii) the other party shall be entitled to specific performance and injunctive and equitable relief in addition to any other remedy to which it may be entitled at law or in equity.
