SUBURBAN PROPANE, L.P. SEVERANCE PROTECTION PLAN



 Exhibit 10.4 
 SUBURBAN PROPANE, L.P. 
 SEVERANCE PROTECTION PLAN 

As Adopted in September 1996 and Amended in January 2008, January 2009 and November 2009 

The Board of Supervisors of Suburban Propane Partners, L.P. (the “Partnership”), Suburban Propane, L.P. (“Suburban”),
and all direct or indirect subsidiaries of Suburban, has adopted a program (referred to herein as the “Severance Protection Plan” or the “Plan”) designed to protect certain key employees from the effects of an actual or possible
Change in Control (as defined below), and thereby to enable Suburban to obtain the continued availability of such key employees’ services, managerial skills and business experience upon the threat or actual occurrence of a Change in Control.

 An employee of Suburban or any of its subsidiaries who (a) received an unvested 2003 Long Term Incentive Plan (together
with any successor plan thereto, the “LTIP”) award during the fiscal year in which the Change in Control occurred, or (b), alternatively, if the Change in Control occurs on the first day of Suburban’s fiscal year, received an unvested
LTIP award during the fiscal year immediately preceding the fiscal year in which the Change in Control occurred, or (c) Suburban agreed in writing would receive an unvested LTIP award at the commencement of the Suburban fiscal year immediately
following the Change in Control, or (d), alternatively, if the Change in Control occurs on the first day of Suburban’s fiscal year, Suburban agreed in writing would receive an unvested LTIP award at the commencement of the Suburban fiscal year
in which the Change in Control occurred is eligible for benefits under this Severance Protection Plan unless otherwise provided by written agreement between such employee and Suburban. 

An employee who is eligible for benefits under this Plan will become entitled to benefits under the Plan if there is a loss of his or her
employment within one year following a Change in Control. In such event, the employee will be entitled to receive (in lieu of any other severance benefits to which he or she may be entitled) the following in accordance with his or her title on the
date on which the Change in Control occurred: 
 Employees that have attained the title of vice president, chief financial
officer, general counsel and higher: 
 a lump-sum benefit equal to the product of seventy-eight (78) times 1/52 of the sum
of the employee’s base annual salary and Target Cash Bonus, defined as the percentage (established by Suburban as of the later of the start of the fiscal year or commencement of employment) of the employee’s annual base salary that would
be paid as a cash bonus to the employee if, for that fiscal year, actual EBITDA equals the Partnership’s budgeted EBITDA, without regard to whether the Target Cash Bonus was earned or paid, as of the date of the Change in Control (but not lower
than the highest sum of such amounts at any time during the period beginning one year prior to the Change in Control and ending on the employee’s termination date). The benefit shall be paid within 30 days following the employee’s
termination of employment. 
 All other eligible employees: 

a lump-sum benefit equal to the product of sixty-five (65) times 1/52 of the sum of the employee’s base annual salary and Target
Cash Bonus, defined as the percentage (established by Suburban as of the later of the start of the fiscal year or commencement of employment) of the employee’s annual base salary that would be paid as a cash bonus to the employee if, for that
fiscal year, actual EBITDA equals the Partnership’s budgeted EBITDA, without regard to whether the Target Cash Bonus was earned or paid, as of the date of the Change in Control (but not lower than the highest sum of such amounts at any time
during the period beginning one year prior to the Change in Control and ending on the employee’s termination date). The benefit shall be paid within 30 days following the employee’s termination of employment. 







 Each employee who becomes entitled to receive benefits under this Plan shall also receive
payment for (a) all annual incentive bonus awards earned but unpaid for all fiscal years completed prior to the Change in Control and for all fiscal years completed prior to the employee’s termination of employment, plus (b) for any
partially completed fiscal year during which the employee’s termination of employment occurred, a payment equal to his or her then current Target Cash Bonus, multiplied by a factor equal to a numerator representing the number of full and
partial months of service during the partially completed fiscal year and a denominator of twelve. Any amounts payable under this paragraph shall be paid within 30 days following the employee’s termination of employment. 

For purposes of this Plan, an employee shall be deemed to have lost his or her employment if (a) the employee’s employment is
terminated by Suburban or its successor (unless such termination is due to willful malfeasance in office as that term is defined below), or (b) the employee’s employment is terminated by the employee subsequent to one of the following
events (each a “Good Reason”): (i) a material diminution of the employee’s authority, duties, responsibilities or status; (ii) a material diminution in the authority, duties, responsibilities or status of the supervisor to
whom the employee is required to report, including, but not limited to, a requirement that the employee report to a company officer (or subordinate employee) instead of directly to the Board of Supervisors; (iii) a reduction of 5% or greater in
the employee’s base annual salary, or a failure to provide the employee with the opportunity to participate, on terms no less favorable than those existing immediately prior to the Change in Control, in any incentive bonus, savings, pension or
other employee benefit plan of Suburban in effect immediately prior to the Change in Control (or successor plans and benefits which are, in the aggregate, no less favorable to the employee than those plans and benefits available to the employee
immediately prior to the Change in Control); or (iv) a requirement, without the employee’s consent, that the employee be based more than 35 miles from his or her present office location if, and only if, the new location is farther from the
employee’s place of residence than the office in which the employee performed services for Suburban or its affiliates prior to the Change in Control. The term “willful malfeasance in office” shall require a finding with respect to the
circumstances under consideration that the employee did not act in a manner he or she reasonably believed to be in, or not opposed to, the best interests of Suburban. 
 Prior to voluntary termination of employment for any of the four Good Reasons listed in subsection (b) of the preceding paragraph, and within 90 days of first becoming aware that one or more
such Good Reasons has occurred, the employee must notify the Vice President or other highest ranking individual in charge of Human Resources, by certified mail, of such event, informing him or her that Suburban or, if applicable, a successor entity
has 30 business days (the “Cure Period”) from the date on which the notification was mailed to remedy such Good Reason. 
 If, for any reason, the twelve month anniversary of the Change in Control event occurs on, or within 30 days following, the date the foregoing notification was mailed to the Vice President or other
highest ranking individual in charge of Human Resources, then the twelve-month severance protection period provided under this Plan shall be extended until the expiration of ten business days beyond the conclusion of the Cure Period. 

“Change of Control” shall mean: 
 (a) the date (which must be a date subsequent to the Effective Date) on which any Person (including the Partnership’s general partner) or More than One Person Acting as a Group (other than the
Partnership and/or its Subsidiaries) acquires, during the 12 month period ending on the date of the most recent acquisition, Common Units or other voting equity interests eligible to vote for the election of Supervisors (or of any entity,
including the Partnership’s general partner, that has the same authority as the Board to manage the affairs of the Partnership) (“Voting Securities”) representing thirty percent 30% or more of the combined voting power of the
Partnership’s then outstanding Voting Securities; provided, however, that in determining whether a Change of Control has occurred, Voting Securities which have been acquired in a “Non-Control Acquisition” shall be excluded from
the numerator. A “Non-Control Acquisition” shall mean an acquisition of Voting Securities (x) by the Partnership, any of its Subsidiaries and/or an employee benefit plan (or a trust forming a part thereof) maintained by any one or
more of them, or (y) in connection with a “Non-Control Transaction”; or 







 (b) the date of approval by the limited partners of the Partnership, of (w) a
merger, consolidation or reorganization involving the Partnership, unless (A) the holders of the Voting Securities of the Partnership immediately before such merger, consolidation or reorganization own, directly or indirectly, immediately
following such merger, consolidation or reorganization, at least fifty percent (50%) of the combined voting power of the outstanding Voting Securities of the entity resulting from such merger, consolidation or reorganization (the
“Surviving Entity”) in substantially the same proportion as their ownership of the Voting Securities of the Partnership immediately before such merger, consolidation or reorganization, and (B) no person or entity (other than the
Partnership, any Subsidiary, any employee benefit plan (or any trust forming a part thereof) maintained by the Partnership, any Subsidiary, the Surviving Entity, or any Person who, immediately prior to such merger, consolidation or reorganization,
had Beneficial Ownership of more than twenty five percent (25%) of then outstanding Voting Securities of the Partnership), has Beneficial Ownership of more than twenty five percent (25%) of the combined voting power of the Surviving
Entity’s then outstanding Voting Securities; (x) a complete liquidation or dissolution of the Partnership; or (y) the sale or other disposition of forty percent (40%) of the total gross fair market value of all the assets of the
Partnership to any Person or More than One Person Acting as a Group (other than a transfer to a Subsidiary). For this purpose, gross fair market value means the value of the assets of the Partnership, or the value of the assets being disposed of,
determined without regard to any liability associated with such assets. A transaction described in clause (A) or (B) of subsection (w) hereof shall be referred to as a “Non-Control Transaction;” or 

(c) the date a majority of the members of the Board is replaced during any twelve-month period by the action of the Board taken when
a majority of the Supervisors who are then members of the Board are not Continuing Supervisors (for purposes of this section, the term “Continuing Supervisor” means a Supervisor who was either (A) first elected or appointed as a
Supervisor prior to the Effective Date; or (B) subsequently elected or appointed as a Supervisor if such Supervisor was nominated or appointed by at least a majority of the then Continuing Supervisors); 

Notwithstanding the foregoing, a Change of Control shall not be deemed to occur solely because any Person (the “Subject Person”) acquired
Beneficial Ownership of more than the permitted amount of the outstanding Voting Securities as a result of the acquisition of Voting Securities by the Partnership which, by reducing the number of Voting Securities outstanding, increases the
proportional number of Voting Securities Beneficially Owned by the Subject Person, provided that if a Change of Control would occur (but for the operation of this sentence) as a result of the acquisition of Voting Securities by the Partnership, and
after such acquisition of Voting Securities by the Partnership, the Subject Person becomes the Beneficial Owner of any additional Voting Securities which increases the percentage of the then outstanding Voting Securities Beneficially Owned by the
Subject Person, then a Change of Control shall occur. 
 For purposes of the foregoing definition of Change in Control, “Person” and
“Beneficial Ownership” have the meanings used for purposes of Section 13(d) or 14(d) of the Securities Exchange Act of 1934, as amended, and “More than one Person Acting as a Group” has the same meaning as set forth in
Treasury Regulation 1.409A-3(i)(5)(v)(B). 
 Suburban shall also pay all legal fees and expenses incurred by an employee or
former employee, as the case may be, as a result of such employee’s or former employee’s enforcement of any right or benefit under this Plan, unless a court or arbitrator finds that such employee’s or former employee’s challenge
was frivolous, in which case, Suburban and such employee or former employee shall each bear their respective costs and expenses. 
 The administrator of this Plan shall be the Compensation Committee (the “Committee”) of the Board of Supervisors of the Partnership. The Committee shall have absolute discretionary authority to
determine eligibility for benefits under the Plan and to otherwise construe the terms of the Plan. All benefits under the Plan shall be paid out of the general assets of Suburban, and no eligible employee shall have any interest in any specific
asset of Suburban as a result of participation in the Plan. The receipt of a benefit hereunder shall not cause an eligible employee to be treated as an employee of the Company for any purpose beyond the date of the eligible employee’s actual
termination of employment. 
 This Plan may be amended, modified or terminated by the Committee, except that any termination and
any amendment or modification of this Plan adverse to the interests of employees eligible for benefits hereunder shall not be effective for a period of one year after written notice thereof has been circulated generally to the participants in the
Plan at the time of such termination or amendment. If Suburban shall merge with or consolidate with another entity, or transfer, sell or lease all or substantially all of its assets to another entity, Suburban will require that such successor entity
assume the obligations of Suburban hereunder, and this Plan shall be binding upon such entity whether or not expressly assumed by such entity.
