                            LENDER JOINDER AGREEMENT

     THIS LENDER JOINDER AGREEMENT (this "Joinder"), dated as of May 22, 2003,
is executed by COMMERCEBANK, N.A. (the "Additional Lender") in favor of HUGHES
SUPPLY, INC., a Florida corporation (the "Borrower"), and SUNTRUST BANK, a
Georgia banking corporation, as administrative agent (the "Administrative
Agent") for the lenders (the "Lenders") from time to time party to the Revolving
Credit Agreement, dated as of March 26, 2003, among the Borrower, the Lenders
and the Administrative Agent (as amended, restated, supplemented or otherwise
modified from time to time, the "Credit Agreement"; capitalized terms used
herein and not otherwise defined shall have the meanings assigned to such terms
in the Credit Agreement).

                                    RECITALS

     A. Pursuant to Section 2.4(a) of the Credit Agreement, the Borrower has
elected to increase the Aggregate Revolving Commitment Amount from $252,500,000
to an amount not to exceed $300,000,000, and the Lenders party to the Credit
Agreement on the Closing Date have declined to increase their Revolving
Commitments.

     B. The Additional Lender has agreed to provide a Revolving Commitment to
the Borrower in the amount of $15,000,000 (the "Additional Lender Commitment
Amount") in accordance with the terms of Section 2.4 of the Credit Agreement.

     NOW, THEREFORE, the Additional Lender agrees as follows:

     SECTION 1. Joinder. By its signature below, the Additional Lender hereby
joins the Credit Agreement as a Lender, and establishes a Revolving Commitment
to the Borrower in the amount of the Additional Lender Commitment Amount. The
Additional Lender shall be a party to, and bound by, the Credit Agreement with
the same force and effect as if the Additional Lender had become a Lender on the
Closing Date.

     SECTION 2. Representations and Warranties. The Additional Lender represents
and warrants to the Administrative Agent and the Borrower that this Joinder has
been duly authorized, executed and delivered by it and that the Credit
Agreement, as modified by this Joinder, constitutes the legal, valid and binding
obligation of the Additional Lender, enforceable against it in accordance with
its terms.

     SECTION 3. Effectiveness; Automatic Increase. This Joinder shall become
effective (i) when it shall have been accepted by the Borrower and the
Administrative Agent and (ii) upon receipt by the Additional Lender of an
upfront fee in the amount of $22,500, at which time this Joinder shall be deemed
to be a part of and shall be subject to all the terms and conditions of the
Credit Agreement. Upon the acceptance of this Joinder by the Administrative
Agent, the Aggregate Revolving Commitment Amount shall automatically be
increased by an amount equal to the Additional Lender Commitment Amount and
Annex I of the Credit Agreement shall automatically be

deemed amended to reflect the Revolving Commitment of the Additional Lender
committed hereunder.

     SECTION 4. Lack of Reliance on the Administrative Agent. The Additional
Lender acknowledges that it has, independently and without reliance upon the
Administrative Agent or any other Lender and based on such documents and
information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Joinder and become a Lender under the Credit
Agreement. The Additional Lender acknowledges that it will, independently and
without reliance upon the Administrative Agent or any other Lender and based on
such documents and information as it has deemed appropriate, continue to make
its own decisions in taking or not taking any action under or based on this
Joinder, any related agreement or any document furnished hereunder or
thereunder.

     SECTION 5. Foreign Lenders. To the extent that the Additional Lender is a
Foreign Lender, it certifies that it has delivered all applicable forms and
performed all other actions required under Section 2.21(e) of the Credit
Agreement.

     SECTION 6. Governing Law. THIS JOINDER AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE
LAW (WITHOUT GIVING EFFECT TO THE CONFLICT OF LAW PRINCIPLES THEREOF) OF THE
STATE OF GEORGIA.

     SECTION 7. Execution in Counterparts. This Joinder may be executed in any
number of counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.

     SECTION 8. Notices to Additional Lender. All communications and notices to
the Additional Lender shall be given to it at the address set forth under its
signature below.
