Exhibit 4.5


                             MEMORANDUM OF AGREEMENT


AGREEMENT, dated as of December 31, 2000 (the "Effective Date"), between the
"Parties":

          A.       ENTERPRISES SOLUTIONS, INC. ("ESI").

          B.       WALTRAG A.G.  ( "WALTRAG").

Antecedents:

         On April 2, 2000, ESI executed a Deed Poll under the laws of
         Switzerland (the "Deed Poll") in favor of the holders of $5,000,000
         principal amount of 10% Convertible Notes due April 2, 2001, issued
         pursuant to the Deed Poll (the "Notes"), WALTRAG being the initial
         holder of the Notes, in exchange for the payment to ESI of $5,000,000,
         the purchase price for the Notes. The Notes are convertible into Common
         Stock, par value $.001 per share, of ESI ("Common Stock") at a
         conversion price of 90% of the 22 day moving average price of the
         Company's Common Stock, immediately prior to the conversion request. In
         connection with the issuance of the Notes, WALTRAG was also issued an
         additional Note (the "Additional Note") in the principal amount of
         $250,000, having the same terms and conditions as the $5,000,000
         principal amount of Notes issued under the Deed Poll and warrants to
         purchase 550,000 shares of Common Stock of ESI on or before April 4,
         2003, at an exercise price of $10.00 per share (the "Warrants").

         The Parties wish to restructure the loan to ESI represented by the
         Notes issued pursuant to the Deed Poll and the Additional Note and the
         Warrants to convert into ESI Common Stock the Notes and the Additional
         Notes, and all interest accrued thereunder to the Effective Date of
         this Agreement; to restructure the Warrants; to provide for
         representation on ESI's Board of Directors for a designee of WALTRAG;
         and for the execution of Definitive Agreements (as defined below) to
         evidence the agreements set forth herein.

         NOW, THEREFORE, in furtherance of the antecedents, the Parties have
agreed upon the following matters:

I.       Agreements of the Parties:

         A.        The Parties agree to restructure the loan evidenced by the
                   $5,000,000 principal amount of Notes issued under the Deed
                   Poll in the following manner:

                   o   As of the Effective Date, the holder(s) of the entire
                       $5,000,000 principal amount of the Notes issued under the
                       Deed Poll shall convert said principal amount of Notes
                       into 1,635,000 shares of ESI Common Stock, and interest
                       accrued on



                                       1


                       the Notes through December 31, 2000, shall be converted
                       into an additional 120,000 shares of ESI Common Stock.

                   o   No later than the tenth (10th) business day after the
                       Common Stock of ESI recommences trading on the OTC
                       Bulletin Board or on another recognized securities
                       exchange (the "Exercise Date"), clients of WALTRAG shall
                       exercise 600,000 additional warrants to purchase 600,000
                       shares of ESI Common Stock, at a purchase price of $1.00
                       per share. If the said 600,000 warrants are not exercised
                       on or prior to the Exercise Date, said warrants shall
                       expire, notwithstanding any terms to the contrary set
                       forth in the Warrant Agreement relating to the said
                       warrants. The warrants subject to this agreement shall be
                       designated in agreements executed at the closing of the
                       transactions under the Definitive Agreements, and the
                       holders thereof shall execute appropriate agreements at
                       the closing reflecting the terms agreed to in this
                       paragraph.

                   o   The Additional Note and the Warrants shall be cancelled
                       in exchange for the issuance by ESI of 260,000 shares of
                       its Common Stock. Issuance of said shares of ESI Common
                       Stock shall represent payment for cancellation of the
                       Warrant and payment in full of the principal amount of
                       and all interest accrued through December 31, 2000 on the
                       Additional Note.

                   o   Additional three-year warrants, expiring December 31,
                       2003, to purchase 320,000 shares of ESI Common Stock,
                       exercisable at a price of $1.00 per share, shall be
                       issued to WALTRAG's nominee or nominees at the closing of
                       these transactions under the Definitive Agreements, to
                       incentivize an expeditious closing thereof.

         B.        ESI agrees, effective with the execution of the Definitive
                   Agreements referred to below, to nominate WALTRAG's designee
                   to be an advisory member of ESI's Board of Directors, or
                   alternatively, as WALTRAG may specify, a non-director member
                   of a Planning and Operations Committee to be established by
                   ESI's Board of Directors for this purpose. As such advisory
                   or non-director committee member of ESI's Board of Directors,
                   WALTRAG's designee shall be provided with at least
                   forty-eight (48) hours notice of and an agenda for each and
                   every meeting of ESI's Board of Directors and of its Planning
                   and Operations Committee (if applicable), and shall have the
                   opportunity of participating in each such meeting, whether in
                   person or by conference telephone. ESI further agrees to
                   include WALTRAG's designee as a management nominee for ESI's
                   Board of Directors in ESI's proxy material to be filed with
                   the U.S. Securities and Exchange Commission in February or
                   March, 2001, and to vote, at ESI's Annual Meeting of
                   Stockholders to be held in May or June, 2001, all proxies
                   received by management in favor of such designee's election
                   as a director, unless specified to the contrary on the proxy.

         C.        The transactions agreed to herein shall be detailed in
                   appropriate definitive agreements and financing documents,
                   including any


                                       2


                   amendments to the Deed Poll required to reflect
                   the agreements set forth herein (the "Definitive
                   Agreements"). The Parties intend that the Definitive
                   Agreements shall be executed at a closing to take place as
                   soon as practicable following approval of the transactions
                   set forth herein by ESI Board of Directors. The Definitive
                   Agreements shall be effective as of the Effective Date set
                   forth above.

II.      Dispute Resolution:

         All disputes between the Parties arising from the interpretation of
         this Agreement shall be settled in accordance with the procedures
         applicable to disputes arising under the Deed Poll.

III.     Confidentiality:

         The Parties agree that all information exchanged in the course of the
         discussions relative to the Agreement outlined herein shall be held as
         confidential by the Parties, except as may be required to be disclosed
         pursuant to the Securities Act of 1933, as amended, and the Securities
         Exchange Act of 1934, as amended, and the rules and regulations of the
         U.S. Securities and Exchange Commission promulgated thereunder.
