Item 3. Source and Amount of Funds or Other Consideration: Not applicable. The
        --------------------------------------------------
        transaction giving rise to the filing of this Amendment was an exchange
        of existing Microgy shares for securities of the Company. Mr. Brunner
        purchased the Microgy securities exchanged with personal funds.

Item 4. Purpose of Transaction.
        ----------------------

        On June 23, 2001 (the "Closing Date"), the Company acquired
approximately 87.7% of the outstanding common stock of Microgy in exchange for
securities of the Company pursuant to a Share Exchange Agreement (the "Exchange
Agreement") dated as of June 20, 2001 among the Company, Microgy and the
Principal Microgy Shareholders, as defined therein. Mr. Brunner is a Principal
Microgy Shareholder.

       The Company issued an aggregate of 5,521,549 shares of the Company's
common stock, $.01 par value ("Common Stock") and 197,760.7 shares of the
Company's newly designated Series B Convertible Preferred Stock, $.01 par value
(the "EPC Preferred Stock"), to the Principal Microgy Shareholders in exchange
for 15,919,147 shares of Microgy common stock. Each share of Preferred Stock,
which votes with the Common Stock on an as converted basis, will automatically
be converted into ten shares of Common Stock upon an increase in the authorized
common stock to an amount sufficient to allow conversion of the Preferred Stock.
The exchange ratio (the "Exchange Ratio") used was 0.3468495 shares of Common
Stock and 0.0124228 shares of Preferred Stock for each share of Microgy common
stock. The Exchange Ratio was determined by negotiations among the Company,
Microgy and the primary Principal Microgy Shareholders. The Exchange Ratio is
based on all of the fully diluted equity of Microgy being exchanged for 45% of
the fully diluted equity of the Company, assuming exercise or conversion of all
derivative securities. Pursuant to Section 2.4 of the Agreement, the Exchange
Ratio may be adjusted to reflect certain issuances of equity by the Company to
generate funds to be available for financing Microgy. However, holders of
approximately 94% of the Microgy common stock exchanged have waived their right
to adjustments in the Exchange Ratio. The Principal Microgy Shareholders
included two Microgy shareholders who executed Joinder Agreements, becoming
parties to the Exchange Agreement. At the closing, one of the Principal Microgy
Shareholders also exchanged a warrant to purchase 800,000 shares of Microgy
common stock for a warrant to purchase securities of the Company based on the
Exchange Ratio.

       The Exchange Agreement provides that, within 30 days of the Closing Date,
the Board of Directors of the Company will be enlarged from five to eight

                                                                     Page 4 of 8


members and the three resulting vacancies will be filled by designees of the
Principal Microgy Shareholders (including replacements or substitutes similarly
designated, the "Microgy Designees").

       Under the Exchange Agreement, the Company agreed to offer (the
"Subsequent Offer") the remaining shareholders of Microgy (who own an aggregate
of 2,230,126 shares of Microgy Common, warrants to purchase 850,000 shares of
Microgy common stock and options to purchase 290,000 shares of Microgy common
stock) to exchange for EPC securities based on the Exchange Ratio.

       In connection with and as a condition to the Exchange Agreement, the
following agreements relating to or bearing upon the securities were executed:

       A. A Stockholders' Agreement as of the Closing Date among the Company,
the Principal Microgy Shareholders, Joseph E. Cresci and Donald A. Livingston
(the "Stockholders' Agreement"). Messrs. Cresci and Livingston (the "Majority
Stockholders") are Directors, officers and principal stockholders of the
Company. The Stockholders' Agreement provides among other things, that:

          1. The Company will arrange for a meeting of stockholders to present a
          proposal to increase the authorized Common Stock from 20 million
          shares to a greater number at least sufficient to permit the
          conversion of the Preferred Stock into Common Stock and the parties
          will vote the shares they own or control in favor thereof;

          2. The parties will take all lawful action, including voting the
          shares they own or control, to cause the proportion of Microgy
          Designees to the existing five Directors (including any replacement or
          substitute designated by the Majority Stockholders, the "Incumbent
          Directors"), to remain approximately 3:5 and for the election of the
          Microgy Designees and the Incumbent Directors;

          3. Each Party who is a director of the Company, in such capacity
          (subject to his fiduciary duties to the Company), unless agreed by a
          majority of the then Incumbent Directors, will retain Messrs. Cresci
          and Livingston as Chairman and Chief Executive Officer and President,
          respectively, and not take any action to alter the respective powers
          and functions of such offices;

          4. Each Principal Microgy Shareholder agreed that, unless such
          Principal Microgy Shareholder has been specifically invited in writing
          by a majority of the then Incumbent Directors (or in the case of
          (a)(i) below, has obtained the consent of a majority of the then
          Incumbent Directors), such Principal Microgy Shareholder will not in
          any manner, directly or indirectly, (a) effect or seek, offer or
          propose (whether publicly or otherwise) to effect, or cause or
          participate in or in any way assist any other person to effect or
          seek, offer or propose (whether publicly or otherwise) to effect or
          participate in, (i) in the case of George A. Kast and Benjamin Brant,
          any acquisition of any securities (or beneficial ownership thereof) or
          assets of the Company, or any of its subsidiaries, except as
          contemplated in the Exchange Agreement; (ii) any tender or exchange
          offer or merger or other business combination involving the Company or
          any of its subsidiaries, (iii) any recapitalization, restructuring,
          liquidation, dissolution or other extraordinary transaction with
          respect to the Company or any of its subsidiaries or (iv) any
          "solicitation" of "proxies" (as such terms are used in the proxy rules
          of the Securities and Exchange Commission) or consents to vote any
          voting securities of the Company, except as contemplated in the
          Stockholders' Agreement, (b) form, join or in any way participate in a
          "group" (as defined under the Securities Exchange Act of 1934, as
          amended), with respect to the securities of the Company, except as
          contemplated in the Stockholders' Agreement, (c) otherwise act, alone
          or in concert with others, to seek to control or influence the
          management, Board or policies of the Company, (other than acting as a
          shareholder or director in the ordinary course), (d) take any action
          which might force the Company to make a public announcement regarding
          any of the types of matters set forth in (a) above, (e) advise, assist
          or encourage any other persons in connection with the foregoing, or
          (f) enter into any discussions or arrangements with any third party
          with respect to any of the foregoing.

          5.  The Stockholders' Agreement terminates on June 30, 2003.


                                                                     Page 5 of 8

     B.  A Registration Rights Agreement as of the Closing Date with the
Principal Microgy Shareholders, the Majority Stockholders and those Microgy
security holders who exchange Microgy securities in the Subsequent Offer and
execute counterpart signature pages thereto (collectively, the "Holders") (the
"Registration Rights Agreement").  Pursuant to the Registration Rights
Agreement, the Company agreed to file, by November 30, 2001, a Registration
Statement on behalf of the Holders allowing holders to resell Common Stock and
granted the Holders piggyback registration rights.

     Except as described in this Item 4 and elsewhere in this Schedule 13D, Mr.
Brunner does not have any plans or proposals (in his capacity as a stockholder
of the Company) which relate to or would result in:  (a) the acquisition by any
person of additional securities of the Company, or the disposition of securities
of the Company; (b) an extraordinary corporate transaction, such as a merger,
reorganization or liquidation, involving the Company or any of its subsidiaries;
(c) a sale or transfer of a material amount of assets of the Company or any of
its subsidiaries; (d) any change in the present Board of Directors or management
of the Company, including any plans or proposals to change the number or term of
directors or to fill any existing vacancies on the Board; (e) any material
change in the present capitalization or dividend policy of the Company; (f) any
other material change in the Company's business or corporate structure; (g)
changes in the Company's charter, by-laws or instruments corresponding thereto
or other actions which may impede the acquisition of control of the Company by
any person; (h) causing a class of securities exchange or cease to be authorized
to be quoted in an interdealer quotation system of a registered national
securities association; (i) a class of equity securities of the Company becoming
eligible for termination of registration pursuant to Section 12(g)(4) of the
Act, as amended; or (j) any action similar to those enumerated above.

Item 5.  Interest in Securities of the Issuer:
         ------------------------------------

         (a) Mr. Brunner may be deemed to own beneficially 529,963 shares of
Common Stock as of July 23, 2001, consisting of 390,206 shares of Common Stock
issued under the Exchange Agreement and 139,757 shares of Common Stock issuable
upon conversion of EPC Preferred Stock issued under the Exchange Agreement.

         The shares beneficially owned by Mr. Brunner represent 3.0% of the
class; based on the 11,406,783 shares of Common Stock reported to be outstanding
as of May 14, 2001 in the Company's Form 10-Q filed for the period ending March
31, 1998, plus the 5,521,549 shares of Common Stock issued on July 23, 2001 as
described in Item 4, plus the 139,757 shares of Common Stock Mr. Brunner will
receive upon conversion of his EPC Preferred Shares .

         Mr. Brunner is a party to the Stockholders' Agreement described in Item
4. Within the meaning of Rule 13(d)(5) under the Securities Exchange Act of
1934, as amended (the "Act"), the terms of the Stockholders' Agreement could be
deemed to provide for an agreement among the parties thereto to act together for
the purpose of voting and disposing of equity securities of the Company.
Accordingly, the parties thereto could be deemed to be members of a "group" and
could be deemed to be beneficial owners of all of the securities held by such
group. Mr. Brunner denies the existence of such a group and disclaims beneficial
ownership of the securities held by any other person.

         As of the date hereof, to the best knowledge of Mr. Brunner , the table
below identifies all of the parties to the Stockholders' Agreement, in addition
to Mr. Brunner, and states their ownership interests in the Company as of July
23, 2001, based solely upon public filings and acquisition of the Company's
securities pursuant to the Exchange Agreement.

1   Section 13 of the Exchange Act deems a person to be the beneficial owner of
    a security, if that person has the right to acquire beneficial ownership of
    such security through the conversion of another security if such other
    security was acquired with the purpose or effect of changing or influencing
    the control of the issuer, or as a participant in any transaction having
    such purpose or effect. Therefore, the holders of EPC Preferred Stock may be
