                             STOCKHOLDERS AGREEMENT

   
                  STOCKHOLDERS AGREEMENT, dated as of July 31, 1997, among
SunSource Inc., a Delaware corporation (the "Corporation"), Lehman Brothers (as
hereinafter defined), Donald T. Marshall ("Marshall"), John P. McDonnell
("McDonnell"), Norman V. Edmonson ("Edmonson"), Harold J. Cornelius
("Cornelius"), Max W. Hillman ("Hillman"), Joseph M. Corvino ("Corvino") and the
respective S-corporations of Marshall, McDonnell, Edmonson, Cornelius, Hillman
and Corvino listed on the signature page hereto (Marshall, McDonnell, Edmonson,
Cornelius, Hillman and Corvino and their respective S-corporations being
collectively referred to herein as the "Senior Executives").
    

                                   BACKGROUND

   
                  The Corporation has been formed to accomplish the conversion
(the "Conversion") of SunSource L.P. (the "Partnership") to corporate form. In
the Conversion, Lehman/SDI, Inc., which is the general partner of SDI Partners
I, L.P., the general partner of the Partnership (the "General Partner"), and the
Senior Executives, who are the limited partners of the General Partner, will
receive Common Stock of the Corporation (the "Common Stock") in exchange for
their interests in the General Partner. In addition, affiliates of Lehman
Brothers and the Senior Executives presently own Class B limited partnership
interests in the Partnership which will be converted in the Conversion into
Common Stock. For purposes of this Agreement, "Lehman Brothers" shall mean
Lehman Brothers Holdings Inc., Lehman/SDI, Inc., Lehman Ltd. I, Inc., Lehman
Brothers Capital Partners I, L.P. (or upon dissolution of Lehman Brothers
Capital Partners I, LB I Group, Inc., its general partner) and any other person
affiliated with the foregoing entities to which they distribute shares of Common
Stock received by them in the Conversion.
    

                  The purpose of this Agreement is to provide for certain
restrictions on the sale of Common Stock by the parties after the Conversion,
certain corporate governance matters with respect to the voting of shares of
Common Stock and certain bylaw provisions.

                  NOW, THEREFORE, in consideration of the consideration to be
received by Lehman Brothers and the Senior Executives in the Conversion and the
mutual promises contained herein, the parties agree as follows:

                  Section 1. Sale of Shares of Common Stock. Lehman Brothers and
the Senior Executives each agree that they and their respective affiliates will
not sell any shares of Common Stock which they beneficially own, in a single
transaction or series of related transactions, to any third person or persons
which to the knowledge of Lehman Brothers and the Senior Executives after
reasonable inquiry, would beneficially own after such transactions more than 10%
of the then outstanding Common Stock (or more than 15% of the then outstanding
Common Stock if such person or persons are eligible to report the acquisition of
such shares on Schedule 13G

   



pursuant to Rule 13d-1(b)(1) under the Securities Exchange Act of 1934, as such
rule is currently in effect).

                  Section 2. Voting of Shares. On matters submitted to a vote of
stockholders, Lehman Brothers and the Senior Executives each agree to vote (or
cause to be voted), in the same proportion as the shares of outstanding Common
Stock not owned by them ("Unaffiliated Shares") that are voted on any such
matter, that percentage of Excess Voting Shares held by them at such time that
equals the percentage of outstanding Unaffiliated Shares that are voted on such
matter. "Excess Voting Shares" means the shares of Common Stock beneficially
owned by Lehman Brothers or the Senior Executives, as the case may be (and their
respective affiliates), at any time, that represents voting power in excess of
their respective voting powers immediately prior to the Conversion that they
would have had in a vote of the holders of the Class A Interests and the Class B
Interests voting together as a single class. On matters that are the subject of
action by written consent of stockholders in lieu of meeting, Lehman Brothers
and the Senior Executives each agree to deliver (or cause to be delivered)
written consents with respect to a number of shares of Common Stock equal to the
percentage of outstanding Unaffiliated Shares that have delivered written
consents in such matter times the number of Excess Voting Shares held by each of
them.

                  Section 3. Board of Directors. The Board of Directors of the
Corporation shall consist of nine directors, of whom three directors may be
nominated by management, four will be Independent Directors (as defined in the
provision of the Bylaws of the Corporation attached as Exhibit 1) and two
directors may be nominated by Lehman Brothers if Lehman Brothers holds more than
20% of the outstanding shares of Common Stock or one director may be nominated
by Lehman Brothers if Lehman Brothers holds between 10% and 20% of the
outstanding shares of Common Stock. Lehman Brothers and the Senior Executives
each agree to vote the shares of Common Stock owned by them to carry out the
provisions of this section, subject to the provisions of Section 2.

                  Section 4. Bylaw Provision. The bylaws of the Corporation
shall include the provision set forth in Exhibit 1 hereto. Lehman Brothers and
the Senior Executives agree to vote the shares of Common Stock owned by them to
carry out the provisions of the Bylaws, subject to the provisions of Section 2.

   
                  Section 5. Ownership of Interests. Each party hereto
represents and warrants that it is the owner of record and beneficially of the
general or a limited partnership interest in the General Partner described
opposite its name on Exhibit A hereto and that the information in such exhibit
relating to the ulitmate beneficial ownership of such interests is true and
correct.

                  Section 6. Governing Law. This Agreement shall be governed in
all respects, including validity, interpretation and effect, by the laws of the
State of Delaware applicable to contracts made and to be performed in that
State.

                  Section 7. Further Assurances. From and after the date of this
Agreement, the parties hereto shall execute and deliver such instruments,
documents and other writings and take such actions as may be reasonably
necessary to effectuate fully the intent and purpose of this Agreement.
