 AMENDMENT TO 
 PATINA OIL & GAS CORPORATION 
 1996 EMPLOYEE STOCK OPTION PLAN 
  
 This Amendment (the “Amendment”) to the Patina Oil & Gas Corporation 1996 Employee Stock Option Plan (the “Plan”) is adopted as of
September 14, 2004 by the Board of Directors (the “Board”) of Patina Oil & Gas Corporation (the “Company”). 
  
 RECITALS 
  
 WHEREAS, the Board has determined that it is desirable and in the best interests of the Company to amend the Plan to provide that the gain from the
exercise of stock options granted under the Plan may be deferred by the optionee subject to the terms of the Amended & Restated Patina Oil & Gas Corporation Deferred Compensation Plan for Select Employees (the “DCP”); and

  
 WHEREAS, Section 9 of the Plan provides that the Plan may be
amended by the Board. 
  
 NOW, THEREFORE, BE IT RESOLVED, that the
Plan is amended as follows: 
  
 1. A new section 6.13 is hereby
added to the Plan to read as follows: 
  
 6.13
Deferrals. Notwithstanding any other provision of the Plan to the contrary, the Committee may permit or require a Holder to defer such Holder’s receipt of the shares of Stock that would otherwise be due to such Holder by virtue of the
exercise of an Option. If any such deferral election is permitted or required, the Committee shall, in its sole discretion, establish rules and procedures for such payment deferrals. Such deferral may be accomplished under the Company’s Amended
and Restated Deferred Compensation Plan for Select Employees or pursuant to terms and conditions contained in the relevant Option Agreement. The Company may, but is not obligated to, contribute the shares of Stock that would otherwise be issuable
pursuant to the exercise of the Option to a rabbi trust. Shares issued to a rabbi trust pursuant to this Section 6.13 may ultimately be issued to the Holder in accordance with the terms of the DCP or the Option Agreement. In addition, Shares that
would otherwise be issued to the Holder at the time the Option is exercised but for a proper deferral under this Section 6.13 and are distributed from the DCP to the Holder shall be charged against the total number of shares of Stock reserved under
Section 2.1 of the Plan. 
  
 2. All capitalized terms used herein
shall have the meanings assigned to them in the Plan. 

 3. Except as expressly amended hereby, the Plan remains in full force and effect.

undersigned, a duly authorized officer of the Company, as of September 14, 2004.

the Eligible Employee of his or her stock options pursuant to an Employer-sponsored stock option program, into contributions (a “Stock Options Gains Contribution”) to the Eligible Employee’s Account. The value of the Stock Option
Gains Contribution to be credited to the Eligible Employee’s Account shall be the value of the Stock Option Gains. “Stock Option Gains” means the difference in the dollar value, determined as of the date of exercise of the stock
option, between the exercise price of the stock option and the fair market value of the underlying shares of Stock. Any such deferral shall be entered by the Plan Administrator as credited the Patina Stock Subaccount for that Participant.

 Exhibit 10.4 
  
 PATINA OIL & GAS CORPORATION 
 [DIRECTOR][OFFICER] INDEMNIFICATION 
 AGREEMENT 
  
 INDEMNIFICATION AGREEMENT (“Agreement”) dated as of
            , 200     between PATINA OIL & GAS CORPORATION, a Delaware corporation (the “Company”), and [name of director or officer]
(“Indemnitee”). 
  
 Preliminary Statements

  
 Competent and experienced persons are becoming more reluctant to serve
as directors or officers of corporations unless they are provided with adequate protection against claims and actions against them for their activities on behalf or at the request of such corporations, generally through insurance and
indemnification. 
  
 Uncertainties in the interpretations of the statutes and
regulations, laws and public policies relating to indemnification of corporate directors and officers are such as to make adequate, reliable assessment of the risks to which directors and officers of such corporations may be exposed difficult,
particularly in light of the proliferation of lawsuits against directors and officers generally. 
  
 The Board of Directors of the Company, based upon its business experience, has concluded that the continuation of present trends in litigation against corporate directors and officers will inevitably make it more
difficult for the Company to attract and retain directors and officers of the highest degree of competence committed to the active and effective direction and supervision of the business and affairs of the Company and its subsidiaries and affiliates
and the operation of its and their facilities, and the Board deems such consequences to be so detrimental to the best interests of the Company that it has concluded that the Company should act to provide its directors and officers with enhanced
protection against inordinate risks attendant on their positions in order to assure that the most capable persons otherwise available will be attracted to, or will remain in, such positions and, in such connection, such directors have further
concluded that it is not only reasonable and prudent but necessary for the Company to obligate itself contractually to indemnify to the fullest extent permitted by applicable law its directors and certain of its officers and certain persons serving
other entities on behalf or at the request of the Company and to assume, to the maximum extent permitted by applicable law, financial responsibility for expenses and liabilities which might be incurred by such individuals in connection with claims
lodged against them for their decisions and actions in such capacities. 
  
 Section 145 of the General Corporation Law of the State of Delaware, under which law the Company is organized, empowers a corporation organized in Delaware to indemnify persons who serve as directors, officers, employees or agents of the
corporation or persons who serve at the request of the corporation as directors, officers, employees or agents of another corporation, partnership, joint venture, employee benefit plan, trust or other enterprise, and further specifies that the
indemnification provided by such section “shall not be deemed exclusive of any other rights to which those seeking indemnification may be entitled under any by-law, agreement, vote of stockholders or disinterested directors or otherwise,”
and further empowers a corporation to “purchase and maintain insurance” on behalf of such persons “against any liability asserted against Indemnitee or incurred by Indemnitee in any such capacity, or arising out of 

 Indemnitee’s status as such, whether or not the corporation would have the power to indemnify Indemnitee against
such liability under the provisions of said laws. The Certificate of Incorporation, as amended, and By-laws of the Company permit indemnification in accordance with the fullest extent permitted by applicable law. 
  
 The Company has (i) reviewed the type of insurance available to insure the directors and
officers of the Company and of its affiliates against costs, expenses (including attorneys’ fees and disbursements), judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred by them in connection with any
action, suit or proceeding to which they are, or are threatened to be made, a party by reason of their status or decisions or actions in such positions, (ii) studied the nature and extent of the coverage provided by such insurance and the cost
thereof to the Company, (iii) concluded to obtain such insurance and (iv) concluded, in part based upon Company’s decision to obtain such insurance with certain exclusions and limitations, that it would be in the best interests of the Company
and its stockholders for the Company to enter into agreements to indemnify certain of such persons in the form of this Agreement. 
  
 The Company desires to have Indemnitee serve or continue to serve as a director or officer of the Company, or as a director, officer, employee, partner, trustee, agent or
fiduciary of such other corporations, partnerships, joint ventures, employee benefit plans, trusts or other enterprises (each a “Company Affiliate”) of which Indemnitee has been or is serving or will serve on behalf or at the request of or
for the convenience of or to represent the interests of the Company, free from undue concern for unpredictable, inappropriate or unreasonable claims for damages by reason of Indemnitee being, or having been, a director or officer of the Company or a
director, officer employee, partner, trustee, agent or fiduciary of a Company Affiliate or by reason of Indemnitee’s decisions or actions on their behalf. 
  

Indemnitee is willing to serve, or to continue to serve, or to take on additional service for, the Company or the Company’s Affiliates in such aforesaid
capacities on the condition that Indemnitee be indemnified as provided for herein. 
  
 Accordingly, in consideration of the premises and the covenants contained herein, the Company and Indemnitee do hereby covenant and agree as follows: 
  

1. Services to the Company. Indemnitee will serve or continue to serve as a director or officer of the Company (in the case of a Company
officer, at the will of the Company or under separate contract, if any such contract exists or shall hereafter exist) or as a director, officer, employee, partner, trustee, agent or fiduciary of a Company Affiliate faithfully and to the best of
Indemnitee’s ability so long as Indemnitee is duly elected and qualified in accordance with the provisions of the By-laws or other applicable constitutive documents thereof; provided, however, that (i) Indemnitee may at any time and for
any reason resign from such position (subject to any contractual obligations which Indemnitee shall have assumed apart from this Agreement) and (ii) neither the Company nor any Company Affiliate shall have any obligation under this Agreement to
continue the Indemnitee in any such position. 
  
 2. Right to
Indemnification. The Company shall, to the fullest extent permitted by applicable law as then in effect, indemnify any Indemnitee who is or was involved in any manner (including, without limitation, as a party or a witness) or is threatened to
be made so involved in any threatened, pending or completed investigation, claim, action, suit or proceeding, whether civil, criminal, administrative or investigative (including, without limitation, any action, suit or 
  

 2 

 proceeding by or in the right of the Company to procure a judgment in its favor) (a “Proceeding”) by
reason of the fact that such person is or was a director, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, officer, employee or agent of any Company Affiliate against all expenses
(including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such Proceeding; provided, however, that, except as provided in Section 3(d), the foregoing
shall not apply to a director or officer of the Company with respect to a Proceeding that was commenced by such director or officer. Such indemnification shall include the right to receive payment in advance of any expenses incurred by Indemnitee in
connection with such Proceeding, consistent with the provisions of applicable law as then in effect. 
  
 3. Advancement of Expenses; Procedures; Presumptions and Effect of Certain Proceedings; Remedies; Definitions. In furtherance, but not in
limitation, of the foregoing provisions, the following procedures, presumptions and remedies shall apply with respect to advancement of expenses and the right to indemnification hereunder: 
  
 (a) Advancement of Expenses. All reasonable expenses incurred by or
on behalf of the Indemnitee in connection with any Proceeding shall be advanced to the Indemnitee by the Company within 20 calendar days after the receipt by the Company of a statement or statements from the Indemnitee requesting such advance or
advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the expenses incurred by the Indemnitee and, if required by law at the time of such advance, shall
include or be accompanied by an undertaking by or on behalf of the Indemnitee to repay the amounts advanced if it should ultimately be determined that the Indemnitee is not entitled to be indemnified against such expenses pursuant to this Article.

  
 (b) Procedure for Determination of Entitlement to
Indemnification. (i) To obtain indemnification under this Article, an Indemnitee shall submit to the Secretary of the Company a written request, including such documentation and information as is reasonably available to the Indemnitee and
reasonably necessary to determine whether and to what extent the Indemnitee is entitled to indemnification (the “Supporting Documentation”). The determination of the Indemnitee’s entitlement to indemnification shall be made not
later than 60 calendar days after receipt by the Company of the written request for indemnification together with the Supporting Documentation. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise
the Board in writing that the Indemnitee has requested indemnification. 
  
 (ii) The Indemnitee’s entitlement to indemnification hereunder shall be determined in one of the following ways (each of which shall give effect to the presumptions set forth in Section 3(c)): (A) by a majority
vote of the Disinterested Directors (as hereinafter defined), if they constitute a quorum of the Board; (B) by a written opinion of Independent Counsel (as hereinafter defined) if a quorum of the Board consisting of Disinterested Directors is not
obtainable or, even if obtainable, a majority of such Disinterested Directors so directs; (C) by the stockholders of the Company (but only if a majority of the Disinterested Directors, if they constitute a quorum of the Board, presents the issue of
entitlement to indemnification to the stockholders for their determination) or (D) as provided in Section 3(c). 
  
 (iii) If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 3(b)(ii), a majority of the
Disinterested Directors, if 
  

 3 

 any, shall select the Independent Counsel, but only an Independent Counsel to which the Indemnitee does not reasonably
object. If there shall be no Disinterested Directors, such Independent Counsel shall be selected by a majority of the Directors, but only an Independent Counsel to which the Indemnitee does not reasonably object. 
  
 (c) Presumptions and Effect of Certain Proceedings. Except as
otherwise expressly provided herein, the Indemnitee shall be presumed to be entitled to indemnification hereunder upon submission of a request for indemnification together with the Supporting Documentation in accordance with Section 3(b)(i), and
thereafter the Company shall have the burden of proof to overcome that presumption in reaching a contrary determination. In any event, if the person or persons empowered under Section 3(b) to determine entitlement to indemnification shall not have
been appointed or shall not have made a determination within 60 calendar days after receipt by the Corporation of the request therefor together with the Supporting Documentation, the Indemnitee shall be deemed to be entitled to indemnification and
the Indemnitee shall be entitled to such indemnification unless the Company establishes as provided in the final sentence of Section 3(d)(ii) or by written opinion of Independent Counsel that (A) the Indemnitee misrepresented or failed to disclose a
material fact in making the request for indemnification or in the Supporting Documentation or (B) such indemnification is prohibited by law. The termination of any Proceeding described in Section 2, or of any claim, issue or matter therein, by
judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, adversely affect the right of the Indemnitee to indemnification or create a presumption that the Indemnitee did not
act in good faith and in a manner which the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that the Indemnitee had reasonable cause to believe that
Indemnitee’s conduct was unlawful. 
  
 (d) Remedies of
Indemnitee. (i) In the event that a determination is made pursuant to Section 3(b) that the Indemnitee is not entitled to indemnification hereunder, (A) the Indemnitee shall be entitled to seek an adjudication of Indemnitee’s entitlement to
such indemnification either, at the Indemnitee’s sole option, in (x) an appropriate court of the State of Delaware or any other court of competent jurisdiction or (y) an arbitration to be conducted by a single arbitrator, selected by mutual
agreement of the Company and Indemnitee (or, failing such agreement, by the then sitting Chief Judge of the United States District Court for the District of Colorado), pursuant to the rules of the American Arbitration Association; (B) any such
judicial proceeding or arbitration shall be de novo and the Indemnitee shall not be prejudiced by reason of such adverse determination and (C) in any such judicial proceeding or arbitration the Company shall have the burden of proving that
the Indemnitee is not entitled to indemnification under this Article. If any such determination is made, the Indemnitee shall be entitled, on five days written notice to the Secretary of the Company, to receive the written report of the persons
making such determination, which report shall include the reasons and factual findings, if any, upon which such determination was based. 
  
 (ii) If a determination shall have been made or deemed to have been made, pursuant to Section 3(b) or (c), that the Indemnitee is entitled to
indemnification, the Company shall be obligated to pay the amounts constituting such indemnification within five days after such determination has been made or deemed to have been made and shall be conclusively bound by such determination unless the
Company establishes as provided in the final sentence of this paragraph that (A) the Indemnitee misrepresented or failed to disclose a material fact in 
  

 4 

 making the request for indemnification or in the Supporting Documentation or (B) such indemnification is prohibited by
law. If (x) advancement of expenses is not timely made pursuant to Section 3(a) or (y) payment of indemnification is not made within five calendar days after a determination of entitlement to indemnification has been made or deemed to have been made
pursuant to Section 3(b) or (c), the Indemnitee shall be entitled to seek judicial enforcement of the Company’s obligation to pay to the Indemnitee such advancement of expenses or indemnification. Notwithstanding the foregoing, the Company may
bring an action, in an appropriate court in the State of Delaware or any other court of competent jurisdiction, contesting the right of the Indemnitee to receive indemnification hereunder due to the occurrence of an event described in subclause (A)
or (B) of this clause (ii) (a “Disqualifying Event”); provided, however, that in any such action the Company shall have the burden of proving the occurrence of such Disqualifying Event.  
  
 (iii) The Company shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section 3(d) that the procedures and presumptions of this Section 3 are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is
bound by all the provisions of this Agreement. 
  
 (iv) If the
Indemnitee, pursuant to this Section 3(d), seeks a judicial adjudication of or an award in arbitration to enforce Indemnitee’s rights under, or to recover damages for breach of, this Agreement, the Indemnitee shall be entitled to recover from
the Company, and shall be indemnified by the Company against, any expenses actually and reasonably incurred by the Indemnitee if the Indemnitee prevails in such judicial adjudication or arbitration. If it shall be determined in such judicial
adjudication or arbitration that the Indemnitee is entitled to receive part but not all of the indemnification or advancement of expenses sought, the expenses incurred by the Indemnitee in connection with such judicial adjudication or arbitration
shall be prorated accordingly. 
  
 (e) Definitions. For
purposes of this Section 3: 
  
 “Disinterested
Director” means a director of the Company who is not or was not a party to the Proceeding in respect of which indemnification is sought by the Indemnitee. 
  
 “Independent Counsel” means a law firm or a member of a law firm that neither presently is, nor in the past
five years has been, retained to represent (a) the Company or the Indemnitee in any matter material to either such party or (b) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing,
the term “Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing under the law of the State of Delaware, would have a conflict of interest in representing either the
Company or the Indemnitee in an action to determine the Indemnitee’s rights hereunder. 
  
 4. Other Rights to Indemnification. The indemnification and advancement of costs and expenses (including attorneys’ fees and disbursements) provided by this Agreement shall not be deemed exclusive of any
other rights to which Indemnitee may now or in the future be entitled under any provision of applicable law, the Certificate of Incorporation or any By-law of the Company or any other agreement or any vote of directors or stockholders or otherwise,
whether as to action in Indemnitee’s official capacity or in another capacity while occupying any of the positions or having any of the relationships referred to in Section 1 of this Agreement. 
  

 5 

 5. Duration of Agreement. (a) This Agreement shall be effective from and after the effective date
of the Agreement, and shall continue until and terminate upon the later of (i) the tenth anniversary after Indemnitee has ceased to occupy any of the positions or have any of the relationships described in Section 1 of this Agreement or (ii) (A) the
final termination or resolution of all Proceedings with respect to Indemnitee commenced during such 10-year period and (B) either (x) receipt by Indemnitee of the indemnification to which Indemnitee is entitled hereunder with respect thereto or (y)
a final adjudication or binding arbitration that Indemnitee is not entitled to any further indemnification with respect thereto, as the case may be. 
  
 (b) This Agreement shall be binding upon the Company and its successors and assigns and shall inure to the benefit of Indemnitee and Indemnitee’s
heirs, devisees, executors, administrators or other legal representatives. 
  
 6. Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable under any particular circumstances or for any reason whatsoever (a) the validity, legality
and enforceability of the remaining provisions of this Agreement (including, without limitation, all other portions of any Section, paragraph or clause of this Agreement that contains any provision that has been found to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable), or the validity, legality or enforceability under any other circumstances shall not in any way be affected or impaired thereby and (b) to the fullest extent possible
consistent with applicable law, the provisions of this Agreement (including, without limitation, all other portions of any Section, paragraph or clause of this Agreement that contains any such provision that has been found to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall be deemed revised, and shall be construed so as to give effect to the intent manifested by this Agreement (including the provision held invalid, illegal or
unenforceable). 
  
 7. Identical Counterparts. This
Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an original but all of which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against whom
enforceability is sought needs to be produced to evidence the existence of this Agreement. 
  
 8. Headings. The headings of the paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute part of this Agreement or to affect the construction thereof. 
  
 9. Modifications and Waiver. No supplement, modification or amendment
of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar)
nor shall such waiver constitute a continuing waiver. 
  
 10.
Notifications and Defense of Claim. Indemnitee agrees to notify the Company promptly in writing upon being served with any summons, citation, subpoena, complaint, 
  

 6 

 indictment, information or other document relating to any matter which may be subject to indemnification hereunder,
whether civil, criminal or investigative; provided, however, that the failure of Indemnitee to give such notice to the Company shall not adversely affect Indemnitee’s rights under this Agreement except to the extent the Company shall
have been materially prejudiced as a direct result of such failure. Nothing in this Agreement shall constitute a waiver of the Company’s right to seek participation at its own expense in any Proceeding which may give rise to indemnification
hereunder. 
  
 11. Notices. All notices, requests, demands
and other communications hereunder shall be in writing and shall be deemed to have been duly given if (i) delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed or (ii) mailed by
certified or registered mail with postage prepaid, on the third business day after the date on which it is so mailed, in either case: 
  
 (a) if to Indemnitee:

 or to such other address as may have been furnished to either party by the other party.
