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 Micorgy shares for securities of the Company. Mr.
          Kast 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 Kast 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 adjsuted 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 members
and the three resulting vacancies will be filled by designees


                                                                   Page 4 of 8

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, the
Mr. Kast 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. Kast may be deemed to own beneficially 2,728,978 shares of Common
Stock as of July 23, 2001, consisting of 2,009,318 shares of Common Stock issued
under the Exchange Agreement and 719,996 shares of Common Stock issuable upon
conversion of EPC Preferred Stock issued under the Exchange Agreement.

     The shares beneficially owned by Mr. Kast represent 13.9% 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 719,966 shares of Common Stock Mr. Kast will
receive upon conversion of his EPC Preferred Shares .

     Mr. Kast 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. Kast denies the existence of such a group and disclaims beneficial
ownership of the securities held by any other person.


                                                                   Page 6 of 8

     As of the date hereof, to the best knowledge of Mr. Kast, the table below
identifies all of the parties to the Stockholders' Agreement, in addition to Mr.
Kast, 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 Series B Preferred Shares
    may be deemed to be the beneficial owners of the underlying Common Shares.


(2) Pursuant to Section 13, any shares of Common Stock not outstanding which are
    issuable upon exercise of warrants or conversion of EPC Preferred Stock held
    by a person have been deemed to be outstanding for the purpose of computing
    the percentage of outstanding securities of the class owned by such person
    but have not been deemed to be outstanding for the purpose of computing the
    percentage of the class by any other person.

(3) 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, 2001, plus the 5,521,549 shares of Common Stock issued on July 23, 2001
    as described in Item 4, plus the number of Common Stock this holder will
    receive upon exercise of warrants or conversion of his EPC Preferred Stock
    (as described in Column 4 of the above table).

(4) This includes 277,480 shares of Common Stock which is issuable upon the
    exercise of the Warrant that Mr. Eastman received in connection with the
    Exchange Agreement.

(5) This includes 9,938.24 shares of EPC Preferred Stock which is issuable upon
    the exercise of the Warrant that Mr. Eastman received in connection with the
