         THIS STOCK PLEDGE AGREEMENT (this "Agreement"), dated as of February
15, 1999, by and between KENNETH H. SMITH, an individual resident of the State
of Georgia (the "Pledgor"), and U.S. TECHNOLOGIES INC., a Delaware corporation
("Pledgee").

                                   WITNESSETH:

         WHEREAS, pursuant to that certain promissory note, dated as of the date
hereof, executed by Pledgor in favor of Pledgee in the principal amount of
$1,234,832 (the "Note"), Pledgee has agreed to extend certain financial
obligations to Pledgor; and

         WHEREAS, Pledgor is the owner of 3,000,000 shares of the common stock,
$.02 par value, of the Pledgee; and

         WHEREAS, as a condition to Pledgee's willingness to extend the
financial accommodations to Pledgor evidenced by the Note, Pledgee has required
that Pledgor execute this Agreement in order to further secure the obligations
under the Note and under the agreements and personal guaranties provided by
Pledgor herein;

         NOW, THEREFORE, in consideration of the premises and the covenants set
forth herein the parties hereto agree as follows:

25.      Security for Obligations. This Agreement is given to Pledgee as
         security for the full, prompt and complete performance and satisfaction
         of the agreements and personal guaranties provided by Pledgor herein
         and for the full, prompt and complete payment and performance in full
         when due of the indebtedness under the Note (the obligations of Pledgor
         hereunder and under the Note being referred to, collectively, as the
         "Obligations").

26.      Guaranties. The Pledgor hereby personally, primarily, fully and
         unconditionally guarantees the full, prompt and complete performance
         and satisfaction by Technology Manufacturing & Design, Inc., a Texas
         corporation ("TMD") (51% of the voting stock of which is owned by GWP,
         Inc., a Georgia corporation, which, as of the date hereof, is
         wholly-owned by Pledgor) and by GWP, Inc. of the following:

         (a)      The full, prompt and complete satisfaction and performance by
                  TMD of all of its obligations under and pursuant to the Loan
                  and Security Agreement between TMD and Fidelity Funding, Inc.,
                  dated as of November 30, 1998;

         (b)      The full, prompt and complete satisfaction and performance by
                  TMD of all of its obligations pursuant to Section 8.2 of the
                  Amended and Restated Stock Purchase Agreement between TMD and
                  GWP, Inc., dated as of October 5, 1998;




   2



         (c)      The maintenance by GWP, Inc., at all times during which the
                  Obligations remain outstanding or unsatisfied, of the
                  ownership and control of at least 51% of the voting shares and
                  voting control of TMD; provided that this provision shall be
                  deemed satisfied if Pledgee retains collateral under that
                  certain Stock Pledge and Guaranty Agreement between GWP, Inc.
                  and Pledgee, dated as of the date hereof (the "GWP Pledge
                  Agreement"), which, at all times, is equal to at least 51% of
                  the voting shares and voting control of TMD;

         (d)      The full, prompt and complete satisfaction and performance by
                  GWP, Inc., of all of its obligations and guaranties under and
                  pursuant to the GWP Pledge Agreement; and

         (c)      The full, prompt and complete satisfaction and performance by
                  TMD of all of its obligations under and pursuant to that
                  certain Agreement of Non-Dilution between TMD and Pledgee,
                  dated as of the date hereof (the "TMD Non-Dilution
                  Agreement").

Any failure of TMD or GWP, Inc. to fully, promptly and completely perform and
satisfy the obligations and performance guaranteed by the Pledgor hereby shall
be deemed a breach of the guaranties and agreements herein, and thereby, a
breach of the Obligations.

27.      Pledge of Collateral. Pledgor hereby pledges, assigns, grants a
         security interest in, transfers and delivers unto Pledgee a continuing
         security interest in each of the following (collectively, the

                  Agreement.

         (c)      Pledgor will defend the title to the Collateral and the lien

                  Lien so long as this Agreement shall remain in effect.

         (b)      any representation, warranty or statement made by Pledgor in
                  connection with this Agreement shall have been false or

         (c)      any failure by Pledgor to observe or perform any covenant or
                  agreement set forth in this Agreement.

32.      Remedies.

         (a)      Upon the occurrence of an Event of Default, or at any time
                  during the term of this Agreement at which such Event of
                  Default is continuing, Pledgee is hereby authorized and
                  empowered, at its election and in addition to those rights and
                  remedies provided it in Section 5 of this Agreement, to
                  transfer and register in its or its nominee's name the whole
                  or any part of the Collateral, in which case Pledgee shall be
                  credited with a payment towards the Obligations in an amount
                  equal to the value of the Collateral so transferred.

         (b)      Pledgor agrees that Pledgor will not interfere with any right,
                  power and remedy of Pledgee provided for in this Agreement or
                  now or hereafter existing at law or in equity or by statute or
                  otherwise, or the exercise or beginning of the exercise by
                  Pledgee of any one or more such rights, powers or remedies. No
                  failure or delay on the part of Pledgee to


                                      -26-

   5



                  exercise any such right, power or remedy, and no notice or
                  demand which may be given to or made upon Pledgor by Pledgee
                  with respect to any such remedies, shall operate as a waiver
                  thereof, or limit or impair Pledgee's right to take any action
                  or to exercise any power or remedy hereunder without notice or
                  demand, or prejudice Pledgee's rights as against Pledgor in
                  any respect.

         (c)      The rights and remedies of Pledgee hereunder and under the
                  Note are cumulative and concurrent and may be pursued
                  separately, successively or together at the sole discretion of
                  Pledgee and may be exercised as often as the occasion thereof
                  shall arise. The failure to exercise any such right or remedy
                  shall in no event be construed as a waiver or release thereof.

33.      Miscellaneous.

         (a)      This Agreement shall be binding upon Pledgor and Pledgor's
                  successors and assigns, and shall inure to the benefit of, and

                  assigns. None of the terms or provisions of this Agreement may

         and assigns, is hereby appointed the attorney-in-fact, with full power
         of substitution, of Pledgor for the purpose of carrying out the
         provisions of this Agreement and taking any action and executing any
         instruments which such attorney-in-fact may deem necessary or advisable
         to accomplish the purposes hereof, which appointment as
         attorney-in-fact is irrevocable while the Obligations remain
         outstanding and coupled with an interest.

35.      No Waiver. No failure on the part of Pledgee to exercise, and no delay
         on the part of Pledgee in exercising, any right, power or remedy
         hereunder shall operate as a waiver thereof; nor shall any single or
         partial exercise by Pledgee of any right, power or remedy hereunder

38.      Severability. Any provision of this Agreement which is prohibited or
         unenforceable in any jurisdiction shall not invalidate the remaining
         provisions hereof, and any such prohibition or



                                      -27-
   6



         unenforceability in any jurisdiction shall not invalidate or render
         unenforceable such provision in any other jurisdiction.

         or the enforcement of any provision of this Agreement is brought
         against any party hereto, the prevailing party shall be entitled to
         recover reasonable attorney's fees, costs and disbursements (in
         addition to any other relief to which the prevailing party may be
