                   FIRST AMENDMENT TO ASSIGNMENT AND AGREEMENT

This FIRST AMENDMENT TO ASSIGNMENT AND AGREEMENT (this "First Amendment") is
made and entered into EFFECTIVE as of March 30, 2002, by and between THOMAS H.
HEBERT ("Assignor"), an individual residing in Lutz, Florida; GLOBAL ENERGY &
ENVIRONMENTAL RESEARCH, INC. ("GEER"), a Florida corporation; and GLOBAL ENERGY
GROUP, INC. ("Assignee"), a Delaware corporation.

                              W I T N E S S E T H:

For and in consideration of the mutual promises and covenants herein contained
and the mutual advantages accruing to Assignor and Assignee, and for other good
and valuable consideration the receipt and sufficiency of which are hereby
acknowledged, Assignor and Assignee hereby agree as follows:

1.       BACKGROUND. Assignor and GEER entered into that certain Assignment &
Agreement identified on Exhibit A to this First Amendment (the "Original
Agreement"). For the purposes of this First Amendment, each capitalized term
appearing in this First Amendment shall have the definition applicable to such
term in the First Amendment, unless the context in which such term is used in
this First Amendment clearly indicates otherwise. Assignee has assumed the
operations of GEER, and accordingly the parties have agreed that Assignee should
be substituted for GEER under the Original Agreement. In addition, the parties
have agreed that certain terms of the Original Agreement shall be modified.

2.       ASSIGNMENT, ASSUMPTION AND SUBSTITUTION. GEER does hereby assign to
Assignee all its right, title and interest in, to and under the Original
Agreement, and Assignor does hereby consent and agree to such assignment.
Assignor, Geer and Assignee further agree that (i) Assignee is hereby
substituted for GEER under the Original Agreement, as if Assignor and Assignee
were the original parties to the Original Agreement, (ii) Assignee does hereby
accept, assume and agree to pay and perform, as and when due, and as if Assignee
had been an original party to the Original Agreement, all obligations of GEER
and all obligations of the party designated "Assignee" under the Original
Agreement, (iii) GEER is hereby released from, is no longer a party to, and
shall have no further liability or obligation under or with respect to the
Original Agreement. Geer does hereby grant, bargain, assign and transfer to
Assignee all its right, title and interest in, to and under all Assigned
Products and all Assignor Patent Rights.

3.       ELIMINATION OF INITIAL ROYALTY PAYMENTS. Until April 1, 2004, the
royalty rate under the Original Agreement shall be 0%, and the minimum annual
royalty shall be $0, and no royalty or other payment shall be due or payable
under the Original Agreement until on or after April 1, 2004. All royalty
percentages and minimum annual royalty amounts for periods beginning on or after
April 1 2004 shall be as set forth in the Original Agreement. Notwithstanding
anything to the contrary, however, (i) this Section 3 shall not apply as to any
Assigned Product during any period during which any person or entity not
affiliated with Assignee has the right, by way of a


<PAGE>

license by Assignee to such person or entity, to manufacture, market and sell
such Assigned Product, and (ii) if Assignee sells all or substantially all of
its right, title and interest in, to and under an Assigned Product and the
related Assignor Patent Rights to any person or entity not affiliated with
Assignee, then this Section 3 shall not thereafter apply as to such Assigned
Product.

4.       ADJUSTMENT IN ROYALTY RATES. Every reference in the Original Agreement
to "five percent" or "5%" is amended to read "three percent" or "3%,"
respectively.

5.       DEFINITION OF "GROSS SALES PRICE." The definition in the Original
Agreement of "Gross Sales Price" in Paragraph1.6 of the Original Agreement is
amended by the addition of the following at the end of such definition:

          "When an Assigned Product is included as part of an Assignee Product
         containing, incorporating or including products and materials other
         than Assigned Products, any royalty or other amount payable under this
         Assignment and Agreement shall be payable only with respect to the
         portion of the Gross Sales Price for such Assignee Product allocable to
         the included Assigned Product(s). The Gross Sales Price allocable to
         such included Assigned Product(s) shall be the cost of such Assigned
         Product(s) increased by the markup on the entire Assignee Product.
         Example: ASSIGNEE sells a 10-ton package rooftop unit containing an
         Assigned Product for $5,000. The cost of the entire package is $3,846,
         meaning that the package is sold with a 30% markup. The aggregate cost
         of the Assigned Product(s) included in the system is $540. Accordingly
         the "Gross Sales Price" of such Assigned Product(s) in this example
         would be $702. For the purposes of this paragraph, (i) "Assignee
         Product" means and includes any item, product, system and/or package,
         and/or any collection or aggregation of items, products, systems and/or
         packages, marketed and either licensed or sold by ASSIGNEE, (ii) any
         reference to the "cost" of an Assignee Product or any element,
         component, part or portion of an Assignee Product means the cost
         thereof to ASSIGNEE (or other person selling such Assignee Product) as
         reflected on the books and records of the seller, and (iii) any
         reference to the "markup" on, of or with respect to any Assignee
         Product means the excess, if any, of the gross selling price of such
         Assignee Product over the cost thereof, divided by such cost, expressed
         as a percentage." With respect to any Assigned Product or Assignee
         Product sold by any Licensee, royalties and other amounts are payable
         under this Assignment and Agreement only with respect to the amounts
         actually received by ASSIGNEE and not with respect to the amounts
         received by the Licensee.

Every reference in the Original Agreement to the capitalized term "Gross Selling
Price" is amended to read "Gross Sales Price."

6.       DOCUMENTATION. Each party, at its own expense and without further
consideration, will execute and deliver such other documents, and take such
other action, as may be necessary or appropriate in order to consummate more
effectively the transactions contemplated hereby,


<PAGE>

including in particular as necessary or appropriate to effectuate the transfer
of all Assigned Products and all Assignor Patent Rights to Assignee.

7.       EFFECT OF AMENDMENT; NO OTHER MODIFICATION. This First Amendment
together with the Original Agreement constitute the entire agreement between
Assignor and Assignee as to the subject matter of the Original Agreement and
this First Amendment, and there are no other agreements, understandings,
restrictions, warranties or representations between the parties relating to such
subject matter. To the extent that the Original Agreement is inconsistent with
the terms of this First Amendment, it is superseded and controlled by this First
Amendment. Any provision of the Original Agreement inconsistent with this First
Amendment is hereby amended to be consistent with this First Amendment. Other
than as amended by this First Amendment, the Original Agreement remains in full
force and effect, and, except as modified by this First Amendment, the terms and
provisions of the Original Agreement are hereby ratified and affirmed.

8.       COUNTERPARTS AND FACSIMILE. This First Amendment may be executed in two
counterparts, each of which shall be considered an original, but both of which
together shall constitute one and the same instrument, and shall become
effective when each of the parties has executed at least one of the counterparts
even if both parties have not executed the same counterpart. The parties
expressly acknowledge and agree that the printed product of a facsimile
transmittal shall be deemed to be "written" and a "writing" for all purposes of
the Original Agreement and this First Amendment.

IN WITNESS WHEREOF, the parties hereto have set their hands and seals to
indicate that each of them does fully understand and agree with and to the
foregoing.

         the right to grant licenses to import, make, have made, use and sell
         the Assigned Product throughout the world. ASSIGNEE shall give written
         notice to ASSIGNOR with respect to each license granted by the

<PAGE>

2.3      The assignment of rights hereunder is limited to those rights included
         in Assignor Patent Rights.

                              ARTICLE III - ROYALTY

3.1      In consideration of the Assignment of Paragraph 2.1 of Article II,
         Assignee shall pay Assignor, royalties as set forth in Paragraph 3.2 of
         this Article III.

3.2      ASSIGNEE agrees to pay ASSIGNOR an accrued royalty in the amount of
         five percent (5%) of the Gross Selling Price for each product
         manufactured, distributed, sold, etc. that is covered by/under, or
         becomes covered by a Letters of Patent, derived or accomplished by the
         Patent Application set forth in Paragraph 1.1 of Article I. To the
         extent ASSIGNEE grants a license to a third party under Assignor Patent
         Rights and receives royalties or other remuneration therefor, then
         ASSIGNEE agrees to pay ASSIGNOR five percent (5%) of such royalties

         sold that is covered by/under a Patent Pending Application. Royalties
         will not be paid or disbursed until such time as the actual Patent has
         issued. In the event that a Patent Application is; a) abandoned, b)
         allowed no claims, c) rejected, or d) determined to be without the
         ability to file arguments that would result in Valid Claims, then no
         royalty would be paid, and all royalties accrued would revert to
         ASSIGNEE. In the event a Patent Application results in an issuance of a
         United States Letter of Patents, then all accrued royalties will be
         dispersed in accordance with Paragraphs 6.1 and 6.2 of Article VI.

3.5      Minimum Annual Royalties are as follows:

         Assigned Product.

4.2      ASSIGNEE shall have control of the preparation and prosecution of all
         pending patent applications, in respect to the aforementioned patents
         as covered in the Assigned Product and any pending patent applications,
         in respect to the aforementioned patent application as covered in the
         Assigned Product, included within Assignor Patent Rights.

4.3      ASSIGNEE shall pay for the expenses and costs relating to such
         preparation and prosecution of those applications contemplated by
         Paragraph 4.2 of the Article IV.

4.4      ASSIGNEE shall pay for any taxes, annuities, maintenance fees, renewal
         and extension charges, and other out-of-pocket expenses, and related

         included within the Assignor's Patent Rights.

4.5      Should ASSIGNEE decided, in its sole and absolute discretion, to
         abandon any pending patent application or to stop paying for the
         expenses and costs contemplated by Paragraphs 4.3 and 4.4, ASSIGNEE
         shall so notify ASSIGNOR to allow ASSIGNOR the opportunity to assume
         prosecution of the pending patent application and to begin paying for
         all of the expenses and costs.

                               ARTICLE V - RECORDS

5.1      ASSIGNEE shall submit or cause to be submitted to ASSIGNOR within one
         month following each semi-annual period (six months) a report setting
         forth (1) the number and (2) the Gross Sales Price of the Assigned
         Product, which ASSIGNEE has Commercially Exploited and (3) the amount
         of licensing royalties and remuneration received during that
         semi-annual period and which have not been previously reported.

5.2      ASSIGNEE agrees to keep books and records of account pertaining to
         Paragraph 5.1 of this Article V in such a manner as to permit the
         correctness and accuracy of any of the reports rendered in compliance
         with Paragraph 5.1 of this Article V to be ascertained. ASSIGNEE shall
         permit so much of the books and records thereof as pertain to the
         subject matter of this Assignment and Agreement to be confidentially
         inspected by a certified public accountant or ASSIGNOR'S designate,
         during ordinary business hours, but not more than once each semi-annual
         period, to confirm the correctness and accuracy of the reports rendered
         under Paragraph 5.1 of this Article V.

                     ARTICLE VII - VALIDITY AND INFRINGEMENT

7.1      In the event that a Valid Claim of the patent included in Assignor
         Patent Rights is finally held to be invalid or limited in scope by a
         court of competent jurisdiction from which appeal can no longer be
         taken, ASSIGNEE from the date of entry of the decision of such Court,
         shall be permanently relieved to the extent of such holding of
         invalidity or limitation of scope as to the obligation to pay accrued
         royalties on the Assigned Product in accordance with Paragraph 3.2 of
         Article III, provided that such Assigned Product is not covered by
         another Valid Claim on one or more patents coming with Assignor Patent
         Rights assigned hereunder which have not been held to be invalid or
         limited in scope as provided herein.

7.2      In the event ASSIGNOR and ASSIGNEE agree that a particular Assigned
         Product or the use thereof does not infringe a particular Valid Claim
         of any patent included in Assignor Patent Rights, ASSIGNEE shall
         thereafter be permanently relieved, with respect to any Assigned
         Product or use thereof which is the same as the Assigned Product or use
         thereof, agreed not to be infringed from the Assigned Product, the
         obligation of making further payments to ASSIGNOR which might otherwise
         be due under Paragraph 3.2 of Article III, such relief to be effective
         as of the date of entry, of such date, of such agreement; provided
         however, that the Assigned Product is not covered by another Valid
         Claim of one or more patents within Assignor Patent Rights which have
         not been held or agreed not to be infringed as provided, herein.

7.3      ASSIGNEE may, in its own name, bring or prosecute infringement suits
         against others who are infringing the patents within Assignor Patent
         Rights and shall be entitled to all recovery therefrom. ASSIGNEE shall
         have the full and sole right to control such or other proposed
         litigation and may discontinue any such suit or proposed litigation at
         any time upon giving thirty (30) days written notice of its intent to
         do so, to ASSIGNOR. ASSIGNOR may at their option, thereafter elect to
         continue such suit or other litigation at its own expense as evidenced
         by written notice to ASSIGNEE, and in such event, ASSIGNOR shall be
         entitled to all recovery therefrom, but shall keep ASSIGNEE fully
         advised of the progress of such continued suit or other litigation.


<PAGE>

7.4      It is mutually agreed between the parties nothing herein contained
         shall be construed to require either party to expend money in
         litigation or in the enforcing of Assignor Patent Rights unless it so
         elects and in the event a party proceeds with litigation in the name of
         the other party any cause in which such other party is not voluntarily
         a party, as evidenced by written notice, such party shall and agrees to
         hold harmless the other party from any and all liabilities arising
         thereunder, including, but not limited to, attorneys fees, court costs,
         and damages arising out of counterclaims, cross claims and the like.

7.5      ASSIGNOR represents that he is unaware of any rights of others which
         would be infringed by the Commercial Exploitation of the Assigned
         Product.

                               ARTICLE VIII - TERM

8.1      This Assignment and Agreement shall become effective upon mutual
         execution hereof and shall continue in effect until the expiration of
         the last to expire of the patent in Assignor Patent Rights coming
         hereunder.

8.2      If ASSIGNEE shall have failed in the performance of any of its
         covenants under this Assignment and Agreement, including the payment of
         royalties contemplated by Paragraph 3.2 of Article III, ASSIGNOR may
         terminate this Assignment and Agreement provided (a) ASSIGNOR provides
         ASSIGNEE written notice listing the specific failure of performance,
         (b) ASSIGNEE fails to cure such failure of performance within
         forty-five (45) days following its receipt of such notice, and (c) the
         default is in fact existing. Should a dispute arise over whether the
         default is in fact existing, ASSIGNEE may institute arbitration
