(f)     “Change in Control” means a Corporate Change in which (i) individuals who were directors of
Employer immediately prior to a Control Transaction shall cease, within two years of such Control Transaction to constitute a majority of the Board of Directors of Employer (or of the Board of Directors of any successor to Employer or to a company
which has acquired all or substantially all its assets) other than by reason of an increase in the size of the membership of the applicable Board or the appointment of any successors to any departing directors that is approved by at least a majority
of the individuals who were directors of Employer immediately prior to such Control Transaction or (ii) any entity, person or Group acquires shares of Employer in a transaction or series of transactions that results in such entity, person or
Group directly or indirectly owning beneficially 50% or more of the outstanding shares of Common Stock.

 (h)     “Committee” means
the Compensation Committee of the Board of Directors. 
 (i)     “Corporate Change” means (i) the
dissolution or liquidation of Employer; (ii) a reorganization, merger or consolidation of Employer with one or more corporations (other than a merger or consolidation effecting a reincorporation of Employer in another state or any other merger
or consolidation in which the stockholders of the surviving corporation and their proportionate interests therein immediately after the merger or consolidation are substantially identical to the stockholders of Employer and their proportionate
interests therein immediately prior to the merger or consolidation) (collectively, a “Corporate Change Merger”); (iii) the sale of all or substantially all of the assets of the Company; or (iv) the occurrence of a Change in
Control.

 2 









 (m)     “Employment Termination Date” means the effective
date of termination of Executive’s employment pursuant to Employer policies and applicable law. 
 (n)    
“Executive” means an individual employed by the Employer in the position of Vice President or higher, who has been designated by the Committee to be eligible to participate in the Plan, or who has accepted a written offer of employment
which includes eligibility for participation in this Plan, and who commences employment in such position and capacity as a full-time employee of the Employer. A list of all individuals designated as Executives at any given time shall be appended as
Appendix A to the Plan. Once designated on Appendix A as an Executive under the Plan, such Executive shall remain so designated and shall continue to be an Executive hereunder until the earliest to occur of (i) the date on which such Executive
is removed from Appendix A by action of the Committee or by the Board, (ii) such Executive’s termination of employment for any reason, or (iii) the death of the Executive. 

(o)     “Good Reason” means any of the following actions if taken without Executive’s prior written
consent: (i) following the designation of an Executive by the Compensation Committee on Appendix A to the Plan, any reduction of the multiple or percentage applicable to an Executive, or removal of Executive, through a subsequent amendment to
Appendix A to the Plan, (ii) a material diminution in Executive’s job responsibilities, (iii) a material diminution in Executive’s base compensation; or (iv) any permanent relocation of Executive’s place of business to
a location 50 miles or more from the then-current location, provided such relocation is a material change in geographic location at which Executive must provide substantial services for purposes of Section 409A. Neither a transfer of employment
among Employer and any of its Affiliates, a change in the co-employment relationship, nor a mere change in job title constitutes “Good Reason.” To exercise the right hereunder to terminate for Good Reason, Executive must provide Notice of
Termination to Employer of his belief that Good Reason exists within 60 days of the initial existence of the Good Reason condition, and that notice shall describe the condition(s) believed to constitute Good Reason. Employer shall have 30 days to
remedy the Good Reason condition(s). If not remedied within that 30-day period, Executive may submit a Notice of Termination; provided, however, that the Notice of Termination invoking Executive’s right to terminate his employment for Good
Reason must be given no later than 100 days after the date the Good Reason condition first arose and Executive must actually separate from service no later than 30 days following the date the Notice of Termination is given to the Employer;
otherwise, Executive is deemed to have accepted the condition(s), or the Employer’s correction of such condition(s), that may have given rise to the existence of Good Reason. 

(p)     “Group” means persons who act “in concert” as described in Sections 13(d)(3) and/or
14(d)(2) of the Securities Exchange Act of 1934, as amended. 
 (q)     “Inability to Perform” means
and shall be deemed to have occurred if Executive has been determined under Employer’s long-term disability plan to be eligible for long-term disability benefits. In the absence of Executive’s participation in, application for benefits
under, or existence of such a plan, “Inability to Perform” means a finding by the Committee in its sole discretion that Executive is, despite any reasonable accommodation required by law, unable to perform the essential functions of
Executive’s position because of an illness or injury for (i) 60% or more of the normal working days during six consecutive calendar months or (ii) 40% or more of the normal working days during twelve consecutive calendar months. 

  
 3 









 (r)     “Notice of Termination” means a written notice that
shall (i) indicate the specific termination provision in this Plan relied upon; (ii) in the case of a termination for Inability to Perform, Cause, or Good Reason, set forth in reasonable detail the facts and circumstances claimed to
provide a basis for termination of Executive’s employment under the provision invoked; and (iii) if the termination is by Executive for Good Reason, or by Employer for any reason, specify the Employment Termination Date. The failure by
Employer or Executive to set forth in the Notice of Termination any fact or circumstance that contributes to a showing of Cause or Good Reason shall not waive any right of Employer or Executive or preclude either of them from asserting such fact or
circumstance in connection with a claim or appeal for benefits under this Plan. 
 (s)     “Section
409A” means Section 409A of the Code and the regulations promulgated thereunder, and any other applicable Treasury guidance, as in effect at the time any payment or other action is to be taken under this Plan. 

(t)     “Separation Agreement” means a general release agreement in a form acceptable to Employer which
is not revoked by Eligible Executive prior to the date it becomes effective. 
 ARTICLE II 

EMPLOYMENT. 
 Executives
under this Plan shall be employed on an at-will basis, to the maximum extent permitted by applicable law. This Plan shall not, and shall not be construed or interpreted as, creating a contract of employment with any person. 

ARTICLE III 

COMPENSATION UPON TERMINATION OF EMPLOYMENT 

(a)     Termination of Employment for Any Reason. If Executive’s employment is terminated, Employer shall pay
to Executive (or in the case of death of Executive, to such person as Executive shall designate in a written notice to Employer or, if no such person is designated, to Executive’s estate) any unpaid portion of Executive’s Base Salary
through the Employment Termination Date, any earned but unused vacation according to Employer’s policies then in effect, and any unreimbursed business expenses, at the time and in the manner required by applicable law, but in no event later
than March 15 of the year following the year of the Executive’s death or termination of employment. 
 (b)    
Termination Following Corporate Change. 
 (1)     If, within the two-year period following a
Corporate Change, Executive’s employment with Employer or an Affiliate or successor of Employer is terminated due to a Covered Termination, Executive will be paid the payments described in Section (a) of Article III of this Plan. In
addition, if, within 21 or 45 days after the Employment Termination Date, as applicable, Executive has signed a Separation Agreement and Executive does not revoke such Separation Agreement, in lieu of any payments under


  
 4 









 
Section (b) of Article III of the Rosetta Resources Inc. Executive Severance Plan, Eligible Executive shall be entitled to receive the following amounts: 

(A)     The designated percentage or multiple, as set forth in Appendix A to the Plan as
of the Employment Termination Date of such Executive, multiplied times the Eligible Executive’s Base Salary in effect on the Employment Termination Date; 

(B)     The designated percentage or multiple, as set forth in Appendix A to the Plan as
of the Employment Termination Date of such Executive, multiplied times the Executive’s target performance bonus percentage for one year, utilizing the greater of (i) the target performance bonus percentage for the performance period in
effect on the Employment Termination Date, or (ii) the target performance bonus percentage for the performance period in effect on the day preceding the date of the Corporate Change; 

(C)     Full and immediate vesting of all Employer stock options and restricted stock
awards held by Eligible Executive as of the Employment Termination Date; 
 (D)    
With respect to Employer stock options that are vested as of the Employment Termination Date, Executive may exercise those options according to the terms of the Rosetta Resources Inc. 2005 Long-Term Incentive Plan. 

(2)     The additional payments provided for in Sections (a) and (b) of this Article III shall
be paid in a single lump-sum payment no later than 60 days after the Employment Termination Date, but in no event shall such single lump sum payment be paid later than the March 15 of the year following the year in which the Executive’s
Termination of Employment occurs. 
 (3)     To the extent that any amount payable under Section
(b) of this Article III would be subject to excise taxes under Code Section 4999 by reason of such amount being treated as an excess parachute payment, as defined in Code Section 280G, the Executive shall receive under Section
(b) of Article III either: (i) an amount under Section (b) of Article III, reduced by to the extent necessary so that no payments to the Executive shall be treated as an “excess parachute payment” as such term is defined by
Code Section 280G(b), or (ii) the amount payable under Section (b) of this Article III without regard to the reduction described in subclause (i), immediately above, whichever payment results in the Executive retaining, net after all
applicable income, wage and excise taxes, the greatest benefit. For purposes of clarity and by way of explanation, the provisions set forth in this Subsection (b)(3) of this Article III are intended to reduce the payments otherwise provided for in
this Section (b) only if such reduction in payment results in a greater economic benefit to the Executive as compared to the benefit to the Executive of payment in full of all amounts payable hereunder, after payment of the excise tax
due under Code Section 4999. The determination of the amount to be paid under Section (b)(3) of this Article III will be made at the expense of Employer by Employer’s regular independent accounting firm, which shall provide detailed
supporting calculations to both Employer and Executive. 

  
 5 









 (c)     COBRA Reimbursement. In addition, if Executive’s
employment with Employer or an Affiliate or successor of Employer is terminated or ends under the circumstances set forth in Section (b) of this Article III, and if Executive has signed a Separation Agreement and does not revoke such Separation
Agreement as provided therein, Executive will receive, in addition to any other payments due under this Plan, the following benefit: if, at the time of the Employment Termination Date, Executive participates in one or more group health plans offered
or made available by Employer and Executive is eligible for and elects to receive continued coverage under such plans in accordance with the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) or any successor law,
Employer will reimburse Executive during the 12-month period following the Employment Termination Date, for the difference between the total amount of the monthly COBRA premiums for the same coverage as in effect on the Employment Termination Date,
that are actually paid by Executive for such continued health plan benefits and the total monthly amount of the same premiums charged to active senior executives of Employer for health insurance coverage. Such reimbursement shall be made within the
90-day period following Executive’s payment of each monthly COBRA premium. Provided, however, that Employer’s reimbursement obligation under this Section (c) shall terminate upon the earlier of (i) the expiration of the time
period described above or (ii) the date Executive becomes eligible for health insurance coverage under a subsequent employer’s group health plan without being subject to any preexisting-condition exclusion under that plan, which occurrence
Executive shall promptly report to Employer. Provided further, however, the amount of COBRA reimbursement during a calendar year may not affect the COBRA expenses eligible for reimbursement in any other calendar year. Provided, however, that the
COBRA reimbursement under this Section (c) shall not be made if and to the extent the Employer reasonably determines that such payment may be discriminatory under Code Section 105(h) and the regulations thereunder, or under the Patient
Protection and Affordable Care Act of 2010, as amended, and regulations thereunder. 
 (d)     Exclusive Compensation
and Benefits. The compensation and benefits described in this Article, along with the associated terms for payment, constitute all of Employer’s obligations to Executive with respect to the termination of Executive’s employment with
Employer and/or its Affiliates. However, nothing in this Plan is intended to limit any earned, vested benefits that Executive may have under the applicable provisions of any benefit plan of Employer in which Executive is participating at the time of
the termination of employment. 
 (e)     Compliance with Section 409A. It is the intent of this Plan to
comply with the requirements of Section 409A so that none of the payments and benefits to be provided hereunder will be subject to the income recognition, additional tax and interest imposed under Section 409A, and any ambiguities herein
will be interpreted to so comply. Employer shall not be liable to Executive for any adverse tax consequences imposed upon Executive as a result of Section 409A. Payments under the Plan shall be made only on the date or dates provided herein,
and no acceleration or deferral of any such payments shall be made either by the Employer or at the request of the Executive. Each aforementioned payment is a separate “payment” within the meaning of Treasury Regulation section
1.409A-2(b)(2)(iii). 

  
 6 









 (f)     Specified Employee Determination and Payment. If Employer
determines that Section 409A applies to payments to an Executive under this Plan, and such Executive is a “specified employee” on the date of Executive’s “separation from service,” as those terms are defined in and
pursuant to Section 409A, then, notwithstanding any provision of this Plan to the contrary, no payment of compensation under this Plan which has been determined to be a payment of “deferred compensation” within the meaning of
Section 409A shall be made to Executive during the period lasting six months from the date of Executive’s separation from service unless Employer determines that there is no reasonable basis for believing that making such payment would
cause Executive to suffer adverse tax consequences pursuant to Section 409A. If any payment to Executive is delayed pursuant to the foregoing sentence, such payment instead shall be paid, without interest, on the first business day following
the expiration of the six-month period referred to in the prior sentence. 
 (g)     Payment after Executive’s
Death. In the event of Executive’s death after Executive becomes entitled to a payment or payments pursuant to this Article III, any remaining unpaid amounts shall be paid, at the time and in the manner such payments otherwise would have
been paid to Executive, to such person as Executive shall designate in a written notice to Employer (or, if no such person is designated, to Executive’s estate). Notwithstanding anything herein to the contrary, an Executive who has been
determined to be a “specified employee” who dies following such Executive’s “separation from service”, as provided in Section 409A, but prior to the six (6) month anniversary of the date of Executive’s
“separation from service,” then any amounts payable under this Plan which are determined by the Employer to be subject to Section 409A, payment of which is delayed in accordance with this Article III, will be payable in a lump sum as
soon as administratively practicable after the date of Executive’s death and all other amounts payable under this Plan will be payable in accordance with the payment schedule applicable to each payment or benefit. 

(h)     Offset. To the maximum extent permitted by applicable law, Employer may set off against, and Executive
authorizes Employer to deduct from, any payments due to the Executive, or to Executive’s heirs, legal representatives, or successors, as a result of the termination of the Executive’s employment any amounts which may be due and owing to
Employer or any of its Affiliates by the Executive, whether arising under this Plan or otherwise; provided, however, that any such set off and deduction shall be made only from amounts that are not treated as “deferred compensation”
subject to the requirements of Section 409A, and only in such a manner that complies with applicable laws. 
 ARTICLE IV 

NO OBLIGATION TO PAY. 

With regard to any payment due to Executive under this Plan, to the maximum extent permitted by applicable law, it shall not be a breach of
any provision of this Plan for Employer to fail to make such payment to Executive if (i) Employer is legally prohibited from making the payment; (ii) Employer would be legally obligated to recover the payment if it was made; or
(iii) Executive would be legally obligated to repay the payment if it was made. 

  
 7 









 ARTICLE V 

DEDUCTIONS AND WITHHOLDINGS. 

With respect to any payment to be made to the Executive, Employer shall deduct, where applicable, any amounts authorized by Employee, and
shall withhold and report all amounts required to be withheld and reported by applicable law. 
 ARTICLE VI 

NOTICES. 

(a)     All notices, requests, demands, and other communications required or permitted to be given or made by either party
shall be in writing and shall be deemed to have been duly given or made (1) when delivered personally, or (2) when deposited in the United States mail, first class registered or certified mail, postage prepaid, return receipt requested, to

ARTICLE VII 

MITIGATION.

shall not be required to mitigate the amount of any payment provided for in this Plan by seeking other employment or otherwise, nor shall the amount of any payment provided for in this Plan be reduced by any compensation earned by Executive as the
result of employment by another employer after the date of termination of Executive’s employment with Employer, or otherwise. 

ARTICLE VIII 
 BENEFITS
UNASSIGNABLE. 
 Executive shall not have any right to pledge, hypothecate, anticipate, or in any way create a lien upon any payments or
other benefits provided under this Plan; and no benefits payable under this Plan shall be assignable in anticipation of payment either by voluntary or involuntary acts, or by operation of law, except by will or pursuant to the laws of descent and
distribution. 

  
 8 









 ARTICLE IX 

AMENDMENT AND TERMINATION. 

The Employer may amend or terminate this Plan at any time by action of the Board, subject to the rights of any Eligible Executive who has
incurred a Covered Termination as of the date of such amendment or termination. Provided, however, that the Board may delegate to an appropriate subcommittee of the Board or to a specified officer of the Corporation the authority to amend the Plan
for the purpose of conforming the Plan to the requirements of Section 409A as interpreted in Treasury Regulations or other guidance. 

ARTICLE X 
 GOVERNING
LAW; VENUE. 
 This Plan shall be governed by the laws of the State of Texas except for its laws with respect to conflict of laws, and
except to the extent preempted by any federal law. The exclusive forum for any lawsuit arising from or related to Executive’s employment or this Plan shall be a state or federal court in Harris County, Texas. To the extent this Plan is governed
