formerly known as GeoMet Resources, Inc. (the “Company”), and             , (the “Optionee”), in connection with the grant of an Incentive Option
(hereinafter defined) under the GeoMet, Inc. 2005 Stock Option Plan (the “Plan”). 
  
 W I T N E S S E T H : 
  
 WHEREAS, the Optionee is an employee of the Company or an Affiliate (hereinafter defined) and the Company wishes to encourage the Optionee to own Common Stock (hereinafter defined); and 
  
 WHEREAS, the Optionee formerly held option(s) (the “GeoMet
Option”) to purchase common stock of GeoMet, Inc., an Alabama corporation (“GeoMet”); and 
  
 WHEREAS, GeoMet was merged with and into the Company (the “Merger”); and 
  
 WHEREAS, in connection with the Merger, the Board of Directors of GeoMet took such action to cause the GeoMet Option to be
converted at the effective time of the Merger into an option to purchase Common Stock of the Company pursuant to the formula set forth in the Agreement and Plan of Merger between GeoMet Resources, Inc. and GeoMet, Inc. dated as of March 31,
2005; and 
  
 WHEREAS, as a result of the Merger, the GeoMet
Option automatically became fully vested; and 
  
 WHEREAS, the
Company and the Optionee desire to enter into a new option agreement to reflect the vested nature of the Option and the conversion of the GeoMet Option into the Option (as defined herein). 
  
 NOW, THEREFORE, the Company and Optionee hereby agree as follows: 

 
 1. Definitions. As used in this Agreement, the following terms
shall have the following meanings, respectively: 
  
 (a) “Affiliate” shall have the meaning set forth in Section 2(a) of the Plan and shall include any party now or hereafter coming within that definition. 
  
 (b) “Board” shall mean the Board of Directors of the Company. 

 (c) “Code” shall mean the Internal Revenue Code of 1986, as amended.

  
 (d) “Committee” shall have the
meaning set forth in Section 2(d) of the Plan. 
  
 (e) “Common Stock” shall have the meaning set forth in Section 2(e) of the Plan. 
  
 (f) “Fair Market Value” shall have the meaning set forth in Section 2(h) of the Plan. 
  
 (g) “Incentive Option” shall mean the stock option
granted pursuant to Section 2 of this Agreement that is intended to be or is denominated as an incentive stock option (within the meaning of Section 422 of the Code). 
  
 2. Grant of Incentive Option. Subject to the provisions of this Agreement, and, in particular, the vesting provisions
set forth in Section 4 hereof, the Company hereby grants to Optionee the option to purchase             shares of the Common Stock of the Company at a price of
$            per share (the “Option”), during a period commencing on the Effective Date and terminating on the first to occur of (i) the expiration of seven years from
the date of this Agreement or (ii) when the employment of Optionee by the Company or any of its Affiliates terminates for any reason; provided, however, that if said employment terminates less than seven years from the date hereof other than by
reason of death or disability, then Optionee may exercise this Option, to the extent he was entitled to do so at the date of termination of employment, at any time within three months after such termination but not after the expiration of the
seven-year period; provided further that if said employment terminates less than seven years from the date hereof by reason of Optionee’s becoming permanently and totally disabled (within the meaning of Section 22(e)(3) of the Code), then
Optionee (or Optionee’s legal representative, if Optionee is legally incompetent) may exercise this Option, to the extent he was entitled to do so at the date of such termination, at any time within one year after such termination but not after
the expiration of the seven-year period; and provided further that if said employment terminates less than seven years from the date hereof by reason of Optionee’s death, then the executor or administrator of Optionee’s estate or anyone
who shall have acquired this Option by will or pursuant to the laws of descent and distribution may exercise this Option, to the extent Optionee was entitled to do so on the date of his death, at any time within one year after such death but not
after the expiration of the seven-year period. Anything to the contrary herein notwithstanding, the Option granted hereunder shall terminate immediately upon the termination of Optionee’s employment with the Company or an Affiliate on account
of fraud, dishonesty or the performance of other acts detrimental to the Company or an Affiliate, as determined by the Board in its sole discretion, or for “cause” as defined in any employment agreement that may exist between Optionee and
the Company or an Affiliate, as determined by the Board in its sole discretion. A transfer of employment without interruption of service between or among the Company and any of its Affiliates shall not be considered a termination of employment for
purposes of this Agreement. 
  
 3. Exercise During
Employment. Except as provided in Section 2 hereof, this Option may not be exercised unless Optionee (i) shall have been in the continuous employ of the Company or an Affiliate from the Effective Date to the date of exercise of the
Option and (ii) 

  

 2 

 
agrees to be bound by the terms and conditions of any shareholders agreement in effect among the Company and its shareholders, or any permitted assigns
thereof under such agreement, at the time Optionee first exercises the Option (the “Stockholders’ Agreement”) by executing a counterpart of such agreement. Any shares of Common Stock purchased upon the exercise of this Option
shall be subject to the terms and conditions of the Stockholders’ Agreement. 
  
 4. Vesting. The Option shall be fully vested and exercisable as of the Effective Date by virtue of the fact that the GeoMet Option converted into the Option was fully vested as a result of the Merger.

  
 5. Manner of Exercise. This Option may be exercised by
written notice signed by the person entitled to exercise the same and delivered to the Secretary of the Company or sent by United States registered mail addressed to the Company (for the attention of the Secretary) at its corporate office in
Bessemer, Alabama. Such notice shall state the number of shares of Common Stock as to which this Option is exercised and shall be accompanied by the full amount of the purchase price of such shares, plus the amount of any federal, state or local
taxes required by law to be paid or withheld in connection with such exercise. 
  
 6. Payment. The purchase price for the shares of Common Stock purchased upon exercise of this Option plus the amount of any federal, state or local taxes referred to in Section 5 hereof shall be paid in
cash in United States dollars or otherwise as contemplated by the Plan. 
  
 7. Delivery of Shares. Delivery of the certificates representing the shares of Common Stock purchased upon exercise of this Option shall be made promptly after receipt of notice of exercise and payment. If the Company so elects, its
obligation to deliver shares of Common Stock upon the exercise of this Option shall be conditioned upon its receipt from the person exercising this Option of an executed investment letter, in form and content satisfactory to the Company and its
legal counsel, evidencing the investment intent of such person and such other matters as the Company may reasonably require. If the Company so elects, the certificate or certificates representing the shares of Common Stock issued upon exercise of
this Option shall bear a legend in substantially the following form: 
  
 THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR APPLICABLE STATE SECURITIES LAWS AND MAY NOT BE SOLD OR OTHERWISE 

  

 3 

 
TRANSFERRED UNLESS SUCH SHARES ARE FIRST REGISTERED THEREUNDER OR UNLESS THE COMPANY RECEIVES A WRITTEN OPINION OF COUNSEL, WHICH OPINION AND COUNSEL ARE
ACCEPTABLE TO THE COMPANY, TO THE EFFECT THAT REGISTRATION THEREUNDER IS NOT REQUIRED. 
  
 8. Adjustments. In the event that, before delivery by the Company of all the shares of Common Stock with respect to which this Option is granted, the Company shall have effected a Common Stock split or dividend
payable in Common Stock, or the outstanding Common Stock of the Company shall have been combined into a smaller number of shares, the shares of Common Stock still subject to this Option shall be increased or decreased to reflect proportionately the
increase or decrease in the number of shares outstanding resulting from any such event, and the purchase price per share shall be decreased or increased to make the aggregate purchase price for all the shares then subject to this Option the same as
immediately prior to such stock split, stock dividend or combination. In the event of a reclassification of the shares of Common Stock not covered by the foregoing, or in the event of a liquidation or reorganization (including a merger,
consolidation, spinoff or sale of assets) of the Company or an Affiliate, the Committee shall make such adjustments, if any, as it may deem appropriate in the number, purchase price and kind of shares still subject to this Option. 
  
 9. Committee Authority. Any questions concerning the interpretation of
this Agreement and any controversy which may arise under this Agreement shall be determined by the Committee in its sole discretion. 
  
 10. Transferability. This Option is not transferable otherwise than by will and the laws of descent and distribution and during the lifetime of
Optionee is exercisable only by Optionee or, if Optionee is legally incompetent, by Optionee’s legal representative. 
  
 11. Employment. Nothing in this Agreement confers upon Optionee any right to continue in the employ of the Company or any Affiliate, nor shall this
Agreement interfere in any manner with the right of the Company or any Affiliate to terminate the employment of Optionee with or without cause at any time. 
  
 12. Option Subject to Plan. By execution of this Agreement, Optionee agrees that this Option and the shares of Common Stock to be received upon
exercise hereof shall be governed by and subject to all applicable provisions of the Plan, which provisions are incorporated by reference herein. 
  
 13. Construction. This Agreement is governed by, and shall be construed and enforced in accordance with, the internal laws of the State of
Delaware, without regard to principles of conflicts of law. Words of any gender used in this Agreement shall be construed to include any other gender, unless the context requires otherwise. The headings of the various sections of this Agreement are
intended for convenience of reference only and shall not be used in construing the terms hereof.

 14. Investment Representations. In connection with the grant of the Option to Optionee and at each
time Optionee exercises all or any part of the Option, such Optionee makes or is deemed to make the following representations, warranties, covenants and agreements with the Company: 
  
 (i) Such Optionee is, by virtue of his key position with the Company or an Affiliate and his involvement in
investment matters from time to time, a sophisticated investor and has such knowledge and experience in financial and business matters that such Optionee is capable of evaluating, and has evaluated, the merits and risks of an investment in the
Option or the shares of Common Stock issuable thereunder, as the case may be. 
  
 (ii) Such Optionee has received all of the financial and other information pertaining to the Company or its Affiliates that such Optionee considers necessary to his investment in the Option or the shares of Common
Stock issuable thereunder, as the case may be. 
  
 (iii) Such Optionee is acquiring the Option or the shares of Common Stock issuable thereunder, as the case may be, delivered pursuant to this Agreement for investment purposes and not with a view to making a distribution, sale, transfer,
assignment or other disposition of all or any part thereof, and such Optionee agrees that the Option or the shares of Common Stock issuable thereunder, as the case may be, will not be sold, transferred, assigned or otherwise disposed of by such
Optionee in violation of the Securities Act of 1933, as amended, or any applicable state securities laws. 
  
 (iv) Such Optionee understands and agrees that his right to transfer all or any portion of the Option or the shares of Common Stock
issuable thereunder, as the case may be, is restricted by the terms and provisions of this Agreement and the Stockholders’ Agreement and that he therefore must be prepared to bear the economic risks of his investment for an indefinite period of
time.

 6Federal Tax Allocation Agreement

 EXHIBIT 10.4 
  
 TAX ALLOCATION AGREEMENT 
 AMONG THE MEMBERS OF THE GEOMET RESOURCES, INC. 
 CONSOLIDATED GROUP 
  
  
 THIS AGREEMENT is made as of the 1st day of
January 2001, by and among GeoMet Resources, Inc., a Delaware corporation, and the undersigned corporations. 
  
 RECITALS: 
  
 WHEREAS, GeoMet Resources, Inc. is the common parent of an affiliated group of corporations within the meaning of section 1504(a) of the Internal Revenue Code of 1986, as amended from time to time (the “Code”), and the undersigned
are members of such affiliated group (the “Group”); and 
  
 WHEREAS, the Group files and will file consolidated federal income tax returns (“Federal Returns”) as well as certain consolidated, combined, or unitary state franchise or income tax returns where allowed by law (“State
Returns”); and 
  
 WHEREAS, the parties desire to agree upon
the method for allocating the consolidated United States income tax liability and the unitary, combined, or consolidated state tax liabilities among them and to fairly preserve the economic rights and privileges that would have accrued to each of
them from the filing of separate returns, including benefit of losses and credits utilized in the Federal Returns and the State Returns; 
  
 NOW, THEREFORE, for and in consideration of the mutual covenants hereinafter contained, the parties hereto agree as follows: 
  
 Article 1 - Method of Allocating Consolidated Federal Tax Liability

  
 1.1    If GeoMet Resources, Inc., or
its successor as the common parent within the meaning of section 1504(a) of the Code (the “Common Parent”), files a consolidated United States Corporation Income Tax Return, the total consolidated United States income tax liability after
all credits allowed in arriving at such tax liability (the “Consolidated Federal Tax Liability”) shall be allocated to each member of the Group in accordance with paragraph 1.2. The amount of liability so allocated to any member shall be
an obligation of each such member due and owing in accordance with Article 3. To the extent it is determined that a tax benefit is properly allocable to any member in accordance with the allocation prescribed in paragraph 1.2, the amount of benefit
so allocated shall be an obligation due and owing to each such member in accordance with Article 3. 

 1.2    The members of the Group shall determine and allocate the Consolidated Federal
Tax Liability among themselves in the following manner: 
  
 Step 1: Each member shall be allocated a portion of the Consolidated Federal Tax Liability equal to the Consolidated Federal Tax Liability multiplied by a fraction, the numerator of which is the taxable income of such member and the
denominator of which is the sum of the taxable incomes of all the members. A member’s taxable income shall be the separate taxable income of the member determined under Treasury regulation section 1.1502-12, adjusted for the following items
pursuant to Treasury regulation section 1.1552-1(a)(1)(ii): 
  
 (a)    the portion of the consolidated net operating loss deduction, the consolidated charitable contributions deduction, the consolidated dividends received deduction, the consolidated section 247
deduction, the consolidated section 582(c) net loss, and the consolidated section 922 deduction attributable to such member; 
  
 (b)    such member’s net capital loss and section 1231 net loss, reduced by the portion of the consolidated net
capital loss attributable to such member; and 
  
 (c)    the portion of any consolidated net capital loss carryover attributable to such member that is absorbed in the taxable year. 
  

Step 2: Pursuant to Treasury regulation section 1.1502-33(d)(3), an additional amount shall be allocated to each member equal to 100% of the
excess, if any, of (i) the “separate return tax liability” of such member for the taxable year, over (ii) the amount allocated in Step 1 of this paragraph 1.2. As provided more fully in Treasury regulation section
1.1552-1(a)(2)(ii), a member’s separate return tax liability shall equal the member’s tax liability computed as if it had filed a separate return for the year except that: 
  
 (a)    gain or loss on intercompany transactions shall be taken into account as provided
in Treasury regulation section 1.1502-13 as if a consolidated return had been filed for the year; 
  
 (b)    gain or loss relating to inventory adjustments shall be taken into account as provided in Treasury regulation
section 1.1502-18 as if a consolidated return had been filed for the year; 
  
 (c)    transactions with respect to stock, bonds or other obligations of members shall be reflected as provided in Treasury regulation section 1.1502-13(f) and (g) as if a consolidated return
had been filed for the year; 
  
 (d)    excess losses shall be included in income as provided in Treasury regulation section 1.1502-19 as if a consolidated return had been filed for the year; 
  

 –2– 

 (e)    in the computation of the deduction under section 167,
property shall not lose its character as new property as a result of a transfer from one member to another member during the year; 
  
 (f)    a dividend distributed by one member to another member shall not be taken into account in computing the
deductions under sections 243(a)(1), 244(a), 245, or 247 (relating to deductions with respect to dividends received and dividends paid); 
  
 (g)    basis shall be determined under Treasury regulation sections 1.1502-31 and 1.1502-32, and earnings and profits
shall be determined under Treasury regulation section 1.1502-33 as if a consolidated return had been filed for the year; and 
  
 (h)    subparagraph (2) of Treasury regulation section 1.1502-3(f) shall apply as if a consolidated return had
been filed for the year. 
  
 Step 3: The additional amount
allocated to members pursuant to Step 2 of this paragraph 1.2 shall be paid by such members to the Common Parent on behalf of those other members that had items of income, deductions, net operating losses, or tax credits to which such total is
attributable pursuant to a consistent method that reasonably reflects such items of income, deductions, net operating losses, or tax credits, such consistency and reasonableness to be determined by the Chief Financial Officer of the Common Parent
(the “Chief Financial Officer”). In general, the amounts paid to members will be deemed to be consistent and reasonable if paid on a basis equal to the applicable federal corporate income tax rate of net operating losses used and 100% of
tax credits used unless such an allocation would be inequitable. 
  
 The method of allocation described in this paragraph 1.2 is intended to be consistent with Treasury regulation sections 1.1552-1(a)(1) and 1.1502-33(d)(3) as they currently exist and may hereinafter be amended. 
  
 Article 2 - Method of Allocating Consolidated or Combined State Tax
Liability 
  
 2        In the event the Common Parent files State Returns with any of its subsidiaries, the total state tax liability (“Consolidated State Tax Liability”) shall be allocated in a manner
consistent with the allocation provided in Article 1 of this Agreement for Consolidated Federal Tax Liability as if such State Returns were Federal Returns. 
  
 Article 3 - Authority to Administer Agreement 
  
 3        To effectuate the stated intent of the parties hereto as contained in this Agreement, the Chief Financial
Officer shall be authorized to: 
  
 (a)    determine the Consolidated Federal Tax Liability and the Consolidated State Tax Liability of the Group for each taxable period for which the Common Parent files a 

  

 –3– 

 
Federal Return or a State Return by making the necessary elections and selecting the tax accounting methods that provide the maximum tax benefit for the
Group; 
  
 (b)    determine
and allocate to each member of the Group the appropriate liability or refund, if any, of the Consolidated Federal Tax Liability or the Consolidated State Tax Liability in accordance with paragraph 1.2; 
  
 (c)    prescribe any tax elections or tax
provisions that shall apply to each member of the Group; 
  
 (d)    prescribe the computer software, methods and procedures each member shall use to maintain such member’s tax records and to prepare its tax returns; and 
  
 (e)    do all other things necessary and
proper to effectuate the stated intent of the parties and the purposes of this Agreement. 
  
 Article 4 - Settlement of Allocations 
  
 4        The rights and obligations between and among the various members of the Group accruing under the provisions of this Agreement shall arise and be settled as follows:

  
 (a)    Each member shall
pay the Common Parent its allocated share of Consolidated Federal Tax Liability and Consolidated State Tax Liability, if applicable, under Step 1 of paragraph 1.2 promptly upon request by the Common Parent, and in no event later than 30 days after
the Common Parent files a Federal Return or State Return for any taxable period. 
  
 (b)    Each member benefitting from net operating losses, tax credits, or other tax attributes shall pay to the Common
Parent its additional allocation determined under Step 2 of paragraph 1.2 promptly upon request by the Common Parent, and in no event later than 30 days after the Common Parent files a Federal Return or State Return for any taxable period.

  
 (c)    The Common Parent
shall pay to each member with a net operating loss, tax credits, or other tax attributes during the taxable year, its allocable share of the total of the additional amounts due from other members as determined under Step 3 of paragraph 1.2 promptly
after receipt thereof, and in no event later than 30 days after the Common Parent files a Federal Return or State Return for any taxable period. 
  
 (d)    Notwithstanding any other provisions of this Article 4 to the contrary, the Common Parent may, solely at its
discretion, require each member to pay its allocated share of Consolidated Federal Tax Liability or Consolidated State Tax Liability pursuant to paragraph 4(a) and any additional allocation pursuant to paragraph 4(b) within 30 days after the end of
a taxable period, except that each member’s allocated share and any additional allocation shall be based on the Hypothetical Consolidated Federal Tax Liability or 

  

 –4– 

 
Hypothetical Consolidated State Tax Liability. The Hypothetical Consolidated Federal Tax Liability and Hypothetical Consolidated State Tax Liability shall be
based on a reasonable estimate of the Group’s consolidated tax liability as determined by the Chief Financial Officer. The Common Parent may, solely in its discretion, pay each member with a net operating loss, tax credits, or other tax
attributes during the taxable period, its allocated share of amounts due from other members as soon as is practicable after the end of the taxable period or within 45 days after the end of the taxable period. The parties shall adjust the payments
under paragraphs 4(a), (b) and (c) to take into account payments made under this paragraph 4(d). 
  
 Article 5 - Adjustments 
  
 5    In the event the Consolidated Federal Tax Liability or Consolidated State Tax Liability is subsequently changed or otherwise adjusted by reason of an amended return, a claim for refund, a
final “determination” as that term is defined in section 1313(a) of the Code, or any of the events specified in section 6213(b) or (d) of the Code, or otherwise, the Chief Financial Officer shall adjust the allocations accordingly.
The amounts of any such adjustment shall become due and owing in accordance with Article 4 promptly upon request by the Common Parent, and in no event later than the 30th day following the date giving rise to the recomputation. In the case of any
refund, the Common Parent shall pay each member its share of the refund, determined in the same manner as in paragraph 1.2, promptly after receiving the refund and in no event later than 30 days thereafter, and in the case of an increase in tax
liability, each member shall pay the Common Parent its allocable share of such increased tax liability promptly after receiving notice of such liability from the Common Parent and in no event later than 30 days thereafter. If any interest is to be
paid or received as a result of a consolidated tax deficiency or refund, such interest will be allocated to the parties in the ratio each member’s change in tax liability bears to the total change in tax liability. Any penalty shall be
allocated upon such basis as the Chief Financial Officer deems just and proper in view of all applicable circumstances. 
  
 Article 6 - Miscellaneous Provisions 
  
 6.1    This Agreement supersedes all previous tax allocation agreements among GeoMet Resources, Inc. and the members of the Group and
other federal income tax allocation agreements or arrangements among the parties to this Agreement. 
  
 6.2    It is understood and acknowledged that, in accordance with Treasury regulation section 1.1502-77, the Common Parent will be the
agent for all members of the Group with respect to all matters referred to therein and the Common Parent has the power, without the consent of any member, to exercise the authority with respect to the matters set forth therein, including without
limitation, making or revoking any elections. The Common Parent will also be the agent for the Group with respect to State Returns if applicable state law so provides. 
 6.3    The parties hereto recognize that from time to time other companies may become members of the Group and hereby agree that such new members will become parties to this Agreement by the
signature of an officer of such new member on a document in the form attached 

  

 –5– 

 
hereto as Annex A and it shall not be necessary that the existing members reexecute this Agreement or join with such new member in signing a counterpart of
Annex A. 
  
 6.4    This Agreement shall be
effective for all taxable years beginning on or after January 1, 2001, unless notice of termination of this Agreement is made by any party thereto to the Common Parent within the first 30 days of a taxable year or unless the Common Parent
otherwise agrees to the termination of the rights and obligations of any party hereunder under such terms and conditions as are mutually agreed upon by the Common Parent and the terminating party, which terms and conditions shall not inure to the
detriment of any other party hereto. Allocations to members of the Group that, at the time the allocation is made, have left the Group due to sale, merger, liquidation or otherwise shall be made to the member of the Group that received the proceeds
of sale or the assets of the former member unless another method of allocation is agreed to prior to the member leaving the Group. 
  
 6.5    The Common Parent shall have authority to amend this Agreement through a collateral agreement with any member to take into
account any special facts and circumstances of such member. The collateral agreement shall be effective upon execution by all affected parties and need not be executed by members whose rights and liabilities under this Agreement are not affected by
the collateral agreement. Any such amendment shall be consistent with the principles of this Agreement. 
  
 6.6    This Agreement may be unilaterally amended by the Common Parent in response to legislative or regulatory changes in the tax
law; provided that any such amendment shall be consistent with the principles of this Agreement. 
  
 6.7    Failure of one or more parties to qualify as a member of the Group shall not operate to terminate this Agreement with respect
to the other parties so long as two or more parties continue to so qualify. 
  
 6.8    This Agreement shall bind and inure to the benefit of the respective successors and assigns of the parties; but no assignment shall relieve any party’s obligations hereunder without the
written consent of the other parties except as otherwise provided in paragraph 6.4 
  
 6.9    This Agreement shall be governed by the laws of the State of Texas and the United States of America. 
  

6.10  Any matter not specifically covered by this Agreement shall be handled in the manner determined by the Common Parent in a manner
consistent with the principles of this Agreement. The Chief Financial Officer is authorized to interpret and apply the terms of this Agreement in any reasonable manner. 
  
 6.11  This Agreement contains the entire understanding of the parties with respect to the subject matter contained
herein. No alteration, amendment or modification of any of the terms of this Agreement shall be valid unless made by an authorized officer of each member of the Group that is a party hereto except as otherwise provided in paragraphs 6.5 and 6.6.

  

 –6– 

 6.12  This Agreement may be executed simultaneously in two or more counterparts, each of which
shall be deemed an original, but all of which together shall constitute one and the same instrument.
