Dear Unitholder:

We have previously sent to you proxy material for the Tri-Annual Meeting of
Unitholders of Suburban Propane Partners, L.P. to be held on October 17, 2006.
YOUR BOARD OF SUPERVISORS RECOMMENDS THAT YOU VOTE "FOR" EACH OF ITS NOMINEES
FOR ELECTED SUPERVISOR, APPROVAL OF THE EXCHANGE PROPOSAL, APPROVAL OF THE THREE
SEPARATE PROPOSALS TO AMEND THE PARTNERSHIP AGREEMENT, APPROVAL OF THE AMENDED
AND RESTATED RESTRICTED UNIT PLAN AND APPROVAL OF THE ADJOURNMENT PROPOSAL.

Because the affirmative vote of the holders of a majority of the outstanding
Common Units is needed to adopt certain of the foregoing Proposals, the failure
to vote your proxy will have the same effect as a vote "AGAINST" the adoption of
those Proposals.

Our records indicate that you have not yet voted your units. YOUR VOTE IS
EXTREMELY IMPORTANT. Please save the partnership the expense of additional
follow-up mailings by voting TODAY by telephone, the Internet or by signing,
dating and returning the enclosed proxy card in the postage prepaid envelope
provided.

Thank you for your cooperation.

Very truly yours,


Paul Abel
General Counsel & Secretary
