To Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees:

     This letter relates to the offer by Sysco Food Services of New Jersey
("Purchaser"), a Delaware corporation and a wholly owned subsidiary of Sysco
Corporation, a Delaware corporation ("SYSCO"), to exchange shares of SYSCO
common stock, par value $1.00 per share (the "SYSCO Common Shares"), for each
outstanding share of common stock, no par value, including the associated
preferred stock purchase rights (the "Guest Supply Shares"), of Guest Supply,
Inc., a New Jersey corporation ("Guest Supply"), upon the terms and subject to
the conditions set forth in the preliminary Prospectus dated February 5, 2001
(the "Prospectus") and in the related Letter of Transmittal enclosed herewith
(which, together with any amendments or supplements thereto, constitute the
"Offer"). The Offer is being made in connection with the Merger Agreement and
Plan of Reorganization, dated as of January 22, 2001 (the "Merger Agreement"),
by and among SYSCO, Purchaser and Guest Supply. The Merger Agreement provides,
among other things, that following completion of the Offer, Purchaser will be
merged with and into Guest Supply (the "Merger"), with Guest Supply surviving
the Merger as a wholly owned subsidiary of SYSCO. Please furnish copies of the
enclosed materials to those of your clients for whose accounts you hold Guest
Supply Shares registered in your name or in the name of your nominee. Under the
terms of the Offer, the SYSCO average closing trading price is equal to the
average price of SYSCO Common Shares on the NYSE over the fifteen consecutive
trading days ending on the trading day that is five trading days prior to the
expiration date of the Offer.

     The Offer is subject to several conditions set forth in the Prospectus,
which you should review in detail.

     For your information and for forwarding to your clients for whom you hold
Guest Supply Shares registered in your name or in the name of your nominee, we
are enclosing the following documents:

     tendering Guest Supply Shares and for the information of your clients.
     Facsimile copies of the Letter of Transmittal with manual signatures may be
     used to tender Guest Supply Shares;

          3. The Notice of Guaranteed Delivery to be used to accept the Offer if
     certificates evidencing Guest Supply shares are not immediately available
     or if such certificates and all other required documents cannot be
     delivered to EquiServe Trust Company, N.A. (the "Exchange Agent") on or

     prior to the expiration date of the offer (as defined in the Prospectus) or
     if the procedures for book-entry transfer cannot be completed by the
     expiration date of the offer;

          4. A printed form of letter which may be sent to your clients for
     whose accounts you hold Guest Supply Shares registered in your name or in
     the name of your nominee, with space provided for obtaining such clients'
     instructions with regard to the Offer;

          5. Guidelines for Certification of Taxpayer Identification Number on
     Substitute Form W-9. Stockholders who fail to complete and sign the
     Substitute Form W-9 may be subject to a required federal backup withholding
     tax of 31% of the cash payable to such stockholder or other payee for
     fractional shares pursuant to the Offer;

          6. A return envelope addressed to the Exchange Agent for your use
     only.

     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), Purchaser will accept for exchange Guest Supply Shares which are
validly tendered prior to the expiration date of the offer and not theretofore
properly withdrawn when, as and if Purchaser gives oral or written notice to the
Exchange Agent of Purchaser's acceptance of such Guest Supply Shares for
exchange pursuant to the Offer. Issuance of SYSCO Common Shares and payment of
cash in lieu of a fractional interest, if any, will in all cases be made only
after timely receipt by the Exchange Agent of (i) certificates for such Guest
Supply Shares, or timely confirmation of a book-entry transfer of such Guest
Supply Shares into the Exchange Agent's account at The Depository Trust Company,
pursuant to the procedures described in "The Offer -- Procedure for Tendering"
of the Prospectus, (ii) a properly completed and duly executed Letter of
Transmittal (or a properly completed and manually signed facsimile thereof) or
an agent's message (as defined in the Prospectus) in connection with a
book-entry transfer and (iii) all other documents required by the Letter of
Transmittal.

     Neither SYSCO nor Purchaser nor any officer, director, stockholder, agent
or other representative of SYSCO or Purchaser will pay any fees or commissions
to any broker or dealer or other person (other than the Information Agent and
the Exchange Agent as described in the Prospectus) in connection with soliciting
tenders of Guest Supply Shares pursuant to the Offer.

     Purchaser will, however, upon request, reimburse brokers, dealers,
commercial banks and trust companies for customary mailing and handling costs
incurred by them in forwarding the enclosed materials to their customers.

Guest Supply Shares should be delivered or such Guest Supply Shares should be
tendered by book-entry transfer, all in accordance with the Instructions set
forth in the Letter of Transmittal and in the Prospectus.

     If holders of Guest Supply Shares wish to tender, but it is impracticable
for them to forward their certificates or other required documents or to
