                   6.    TRADE SECRETS.

                         6.1 Employee expressly agrees and understands that the
Company owns and/or controls numerous methods, products, processes, customer
lists, trade secrets and other information applicable to its business and that
it may from time to time acquire, improve or produce additional methods,
products, processes, customer lists, trade secrets and other information
(collectively, the "Confidential Information"). Employee hereby acknowledges
that each element of the Confidential Information constitutes a unique and
valuable asset of the Company, and that certain items of the Confidential
Information have

                                        2

<PAGE>



been acquired from third parties upon the express condition that such items will
not be disclosed other than to the Company in the ordinary course of its
business.

                         6.2 Employee hereby acknowledges that disclosure of the
Confidential Information to and/or use by anyone other than in the Company's
ordinary course of business would result in irreparable and continuing damage to
the Company. Accordingly, the Employee agrees to hold the Confidential
Information in the strictest secrecy, and covenants that, during the Employment
Period or any time thereafter, he will not, without the prior written consent of
the Board of Directors, directly or indirectly, allow any element of the
Confidential Information to be disclosed, published or used, nor permit the
Confidential Information to be discussed, published or used, either by himself
or any third parties, except in effecting the Employee's duties on behalf of the
Company in the ordinary course of business. Notwithstanding anything to the
contrary herein contained, Employee's obligation to maintain the secrecy and
confidentiality of the Confidential Information under this Section 6 shall not
apply to any such Confidential Information which is disclosed through any means
other than as a result of any act by Employee constituting a breach of this
Agreement or which is required to be disclosed under applicable law.

                   7.    EMPLOYEE KNOWLEDGE.

                         7.1 Employee hereby agrees to communicate and make
known to the Company all knowledge possessed by him relating to any methods,
developments, inventions and/or improvements, whether patented, patentable or
unpatentable, which relate to the business of the Company; whether acquired by
him before or during the Employment Period; provided, however, that nothing
herein shall be construed as requiring any such communication where the method,
development, invention and/or improvement is lawfully protected from disclosure
as the trade secret of a third party or by any other lawful bar to such
communications existing prior to the commencement of employment hereunder.

                         7.2 Any methods, developments, inventions and/or
improvements, whether patentable or unpatentable, which Employee may conceive of
or develop in connection with the Company's business (solely or jointly with
another or others), while in its employ, shall be and remain the exclusive
property of the Company. Employee further agrees on request to execute patent
applications, and any other records or memoranda requested by the Company, based
on such methods, developments, inventions and/or improvements, including
instruments deemed necessary by the Company for the prosecution of the patent
application or the acquisition of Letters of Patent of this and any foreign
country or otherwise.

                         7.3 Employee hereby agrees to keep all such records in
connection with the Employee's employment as the Company may from time to time
direct, and all such records shall be the sole and exclusive property of the
Company.

                   8.    RESTRICTIVE COVENANT.

                         8.1 The services of the Employee are unique,
extraordinary and essential to the business of the Company, particularly in view
of the Employee's access to the Confidential Information. Accordingly, the
Employee agrees that if his employment hereunder shall at any time be terminated
for any reason whatsoever, the Employee will not at any time within three (3)
years of such termination, without the prior written approval of the Board of
Directors, directly or indirectly, engage in any business activity competitive
with the business of the Company. Furthermore, the Employee agrees that, during
such three-year period, he shall not solicit, directly or indirectly, any
prospective account of the Company who at the time of such termination was then
actively being solicited by the Company and he shall not in any manner, directly
or indirectly, affect to the Company's detriment any relationship of the Company
with any customer, supplier or employee of the Company or cause any customer or
supplier to refrain from entrusting additional business to the Company. In the
event that any of the provisions of this Section 8.1 shall be adjudicated to
exceed the time, geographic or other limitations permitted by applicable law in
any jurisdiction, then such provision shall be deemed reformed in any such
jurisdiction to the maximum time, geographic or other limitations permitted by
applicable law.

                         8.2 As used in Sections 6, 7 and 8 hereof, the term
"Company" shall mean and include any and all corporations affiliated with
Conserver Corporation of America which either now exist or which may hereafter
be organized.

                   9.    EARLIER TERMINATION.

                         9.1 Employee's employment hereunder shall automatically
be terminated upon the death of the Employee or Employee's voluntarily leaving
the employ of the Company and, in addition, may be terminated, at the sole
discretion of the Company, as follows:

                                      (a) upon thirty (30) days' prior written
                           notice by the Company, in the event of the Employee's
                           disability as set forth in Section 9.2 below; or

                                      (b) upon thirty (30) days' prior written
                           notice by the Company, in the event that the Company
                           terminates the Employee's employment hereunder for
                           cause as set forth in Section 9.3 below.

                         9.2 Employee shall be deemed disabled hereunder if, in
the opinion of the Board of Directors of the Company, as confirmed by competent
medical advice, he shall become physically or mentally unable to perform his
duties for the Company hereunder and such incapacity shall have continued for
any period of six (6) consecutive months.

                         9.3 For purposes hereof, "cause" shall include, but not
be limited to, the following: (a) Employee's willful malfeasance or gross
negligence; (b) any material

                                        4

<PAGE>



misrepresentation or concealment of a material fact made by Employee in
connection with this Agreement; or (c) the material breach of any covenant made
by Employee hereunder.

                         9.4 In the event that this Agreement shall be
terminated due to the Employee's death or disability, then the Company shall pay
to the Employee or his personal representatives, as the case may be, severance
pay in a lump sum amount equal to his compensation for a period of six months as
set forth in Sections 4.1 and 4.2 hereof. If, however, this Agreement shall be
terminated for any other reason whatsoever, then the Company shall not be
obligated to make any severance payments whatsoever to the Employee hereunder,
except for the compensation set forth in Sections 4.1 and 4.2 hereof which shall
have accrued but be unpaid at the effective time of termination.

                   10.   INJUNCTIVE RELIEF.

                         Employee hereby acknowledges and agrees that, in the
event he shall violate any provisions of Sections 6, 7 and 8 hereof, the Company
will be without an adequate remedy at law and, accordingly, will be entitled to
enforce such restrictions by temporary or permanent injunctive or mandatory
relief obtained in any action or proceeding instituted in any court of competent
jurisdiction without the necessity of proving damages and without prejudice to
any other remedies which it may have at law or in equity.

                   11.   SERVICE AS DIRECTOR.

                         During the Employment Period, the Employee shall, if
elected or appointed, serve as a Director of the Company and/or any subsidiary
or affiliate of the Company upon such terms as shall be mutually agreed upon by
the Employee and the Company.

                   12.   ASSIGNMENT.

                         This Agreement, as it relates to the employment of the
Employee, is a personal contract and the rights and interests of the Employee
hereunder may not be sold, transferred, assigned, pledged or hypothecated,
except as set forth in this Section 12 hereof. Except as otherwise herein
expressly provided, this Agreement shall inure to the benefit of and be binding
upon the Company and its successors and assigns, including without limitation,
any corporation or other entity into which the Company is merged or which
acquires all of the outstanding shares of the Company's capital stock, or all or
substantially all of the assets of the Company.


                   13.   RIGHT TO PAYMENTS.

                         Employee shall not under any circumstances have any
option or right to require payments hereunder otherwise than in accordance with
the terms hereof. To the extent permitted by law, the Employee shall not have
any power of anticipation, alienation or assignment of payments contemplated
hereunder, and all rights and benefits of the Employee

                                        5

<PAGE>



shall be for the sole personal benefit of the Employee, and no other person
shall acquire any right, title or interest hereunder by reason of any sale,
assignment, transfer, claim or judgment or bankruptcy proceedings against the
Employee.

                   14.   NOTICES.

                         Any notice required or permitted to be given pursuant

                         This Agreement shall be governed by, and construed and
enforced in accordance with, the laws of the State of New York, without giving
effect to principles of conflicts of law.


                   16.   WAIVER.

                         The waiver by either party of a breach of any provision
of this Agreement shall not operate or be construed as a waiver of any
subsequent breach. If any provision of this Agreement shall be held to be
invalid or unenforceable, such invalidity or unenforceability shall attach only
to such provision and not in any way affect or render invalid or unenforceable
any other provisions of this Agreement, and this Agreement shall be carried out
as if such invalid or unenforceable provision were not embodied therein.

                   17.   ENTIRE AGREEMENT.

                         This Agreement constitutes the entire agreement between
the parties and there are no representations, warranties or commitments except
as set forth herein. This Agreement supersedes all prior and contemporaneous
agreements, understandings, negotiations and discussions, whether written or
oral, of the parties hereto relating to the transactions contemplated by this
Agreement; provided, however, that it is the intention of the parties hereto
that this Agreement shall be interpreted and applied in conjunction with the
terms of any option, warrant or other right now in existence or hereinafter
granted to the Employee to acquire shares of capital stock of the Company. In
the event of any conflict, however, the terms of this Agreement shall govern and
prevail. This Agreement may be amended only in writing executed by the parties
hereto affected by such amendment.

                   IN WITNESS WHEREOF, the undersigned have executed this
Agreement as of the day and year first above written.
