TO:      Greenfield Capital Partners LLC
         90 Grove Street
         Ridgefield, CT 06877

         In connection with your engagement pursuant to our letter agreement of
even date herewith (the "engagement"), the Company agrees to indemnify and hold
harmless Greenfield Capital Partners LLC ("Greenfield" or "you") and its
affiliates, the respective directors, officers, partners, agents and employees
of Greenfield and its affiliates, and each other person, if any, controlling
Greenfield or any of its affiliates (collectively, "INDEMNIFIED PERSONS"), from
and against, and we agree that no Indemnified Person shall have any liability to
us or our owners, parents, affiliates, security holders or creditors for, any
losses, claims, damages or liabilities (including actions or proceedings in
respect thereof) (collectively "LOSSES") (A) related to or arising out of (i)
our actions or failures to act (including statements or omissions made, or
information provided in writing, by us or our agents) or (ii) actions or
failures to act by an Indemnified Person with our consent or in reliance on our
actions or failures to act, or (B) otherwise related to or arising out of the
Engagement or your performance thereof, except that this clause (B) shall not
apply to any Losses that are finally judicially determined to have resulted
primarily from your bad faith or gross negligence or breach of the letter
agreement. If such indemnification is for any reason not available or
insufficient to hold you harmless, we agree to contribute to the Losses involved
in such proportion as is appropriate to reflect the relative benefits received
(or anticipated to be received) by us and by you with respect to the Engagement
or, if such allocation is judicially determined unavailable, in such proportion
as is appropriate to reflect other equitable considerations such as the relative
fault of us on the one hand and of you on the other hand; PROVIDED, HOWEVER,
that, in no event shall the amount to be contributed by you exceed the fees
actually received by you under the Engagement.

         We will reimburse each Indemnified Person for all expenses (including
reasonable fees and disbursements of counsel) as they are incurred by such
Indemnified Person in connection with investigating, preparing for or defending
any action, claim, investigation, inquiry, arbitration or other proceeding
("ACTION") referred to above (or enforcing this agreement or any related
engagement agreement), whether or not in connection with pending or threatened
litigation in which any Indemnified Person is a party, and whether or not such
Action is initiated or brought by you. We further agree that we will not settle
or compromise or consent to the entry of any judgment in any pending or
threatened Action in respect of which indemnification may be sought hereunder
(whether or not an Indemnified Person is a party therein) unless we have given
you reasonable prior written notice thereof and used all reasonable efforts,
after consultation with you, to obtain an unconditional release of each
Indemnified Person from all liability arising therefrom. In the event we are
considering entering into one or a series of transactions involving a merger or
other business combination or a dissolution or liquidation of all or a
significant portion of our assets, we shall promptly notify you in writing, If
requested by Greenfield, we shall then establish alternative means of providing
for our obligations set forth herein on terms and conditions reasonably
satisfactory to Greenfield.

         If multiple claims are brought against you in any Action with respect
to at least one of which indemnification is permitted under applicable law and
provided for under this agreement, we agree that any judgment, arbitration award
or other monetary award shall be conclusively deemed to be based on claims as to
which indemnification is permitted and provided for. In the event that you are
called or subpoenaed to give testimony in a court of law, we agree to pay your
expenses related thereto. Our obligations hereunder shall be in addition to any
rights that any Indemnified Person may have at common law or otherwise. Solely
for the purpose of enforcing this agreement, we hereby consent to personal
jurisdiction and to service and venue in any court in which any claim which is
subject to this agreement is brought by or against any Indemnified Person. We
acknowledge that in connection with the Engagement you are acting as an
independent contractor with duties owing solely to us. YOU HEREBY AGREE, AND WE
HEREBY AGREE ON OUR OWN BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW,
ON BEHALF OF OUR SECURITY HOLDERS, TO WAIVE ANY RIGHT TO TRIAL BY JURY WITH
RESPECT TO ANY CLAIM, COUNTER-CLAIM OR ACTION ARISING OUT OF THE, ENGAGEMENT,
YOUR PERFORMANCE THEREOF OR THIS AGREEMENT.

         The provisions of this agreement shall apply to the Engagement
(including related activities prior to the date hereof) and any modification
thereof and shall remain in full force and effect regardless of the completion
or termination of the Engagement. This agreement and any other agreements

      The Company is entitled, at its option, to convert, at any time and from

herein.  The date upon which the conversion shall be effective (the
"Conversion Date") shall be deemed to be the date set forth in the Conversion
Notice.  The Conversion Shares shall be delivered to the Holder at the address
indicated herein.

      Section 1.03  Reservation of Common Stock.  The Company shall reserve
and keep available out of its authorized but unissued shares of Common Stock,
solely for the purpose of effecting the conversion of this Debenture, such
number of shares of Common Stock as shall from time to time be sufficient to
effect such conversion, based on the Conversion Price.  If at any time the
Company does not have a sufficient number of Conversion Shares authorized and
available, then the Company shall call and hold a special meeting of its
stockholders within sixty (60) days of that time for the sole purpose of
increasing the number of authorized shares of Common Stock.

      Section 1.04   Registration Rights.  The Company is obligated to
register the resale of the Conversion Shares under the Securities Act of 1933,
as amended, or provide Holder with an appropriate exemption from registration.

      Section 1.05   Interest Payments.  The interest so payable will be paid
at the time of maturity or conversion to the person in whose name this
Debenture is registered.  At the time such interest is payable, the Company,
in its sole discretion, may elect to pay

                                2

interest in cash or in the form of Common Stock.  If paid in Common Stock, the
amount of stock to be issued shall be calculated in accordance with the
formula and procedure set forth in Section 1.02 above.

      Section 1.06   Right of Redemption.  The Company shall have the right to
redeem, with thirty (30) business days advance notice to the Holder, any or
all outstanding Debentures remaining in its sole discretion ("Right of
Redemption").  The redemption price shall be equal to 100% of the face amount
of the Debenture redeemed plus all accrued interest ("Redemption Price").

      Section 1.07   Subordinated Nature of Debenture.  This Debenture and all
payments hereon, including principal or interest, shall be subordinated and
junior in right of payment to all accounts payable of the Company incurred in
the ordinary course of business and/or bank debt of the Company not to exceed
$30,000.

                           ARTICLE II.

      Section 2.01   Amendments and Waiver of Default.  The Debenture may be
amended with the consent of Holder.  Without the consent of Holder, the
Debenture may be amended to cure any ambiguity, defect or inconsistency, to
provide assumption of the Company obligations to the Holder or to make any
change that does not adversely affect the rights of the Holder.

                           ARTICLE III.

      Section 3.01   Events of Default.  An Event of Default is defined as
follows: (a) failure by the Company to pay amounts due hereunder within
fifteen (15) days of the date of maturity of this Debenture; (b) failure by
the Company for thirty (30) days after notice to it to comply with any of its
other agreements in the Debenture; (c) events of bankruptcy or insolvency; (d)
a breach by the Company of its obligations under the Registration Rights
Agreement which is not cured by the Company within ten (10) days after receipt
of written notice thereof.  The Holder may not enforce the Debenture except as
provided herein.

      Section 3.02   Failure to Issue Unrestricted Common Stock. As indicated
above, a breach by the Company under its obligation under the Registration
Rights Agreement shall be deemed an Event of Default, which if not cured with
ten (10) days, shall entitle the Holder accelerated full payment of all
debentures outstanding.  The Company acknowledges that failure to honor a
Notice of Conversion shall cause hardship to the Holder.

                           ARTICLE IV.

      Section 4.01   Anti-dilution.  In the event that the Company shall at
any time subdivide the outstanding shares of Common Stock, or shall issue a
stock dividend on the outstanding Common Stock, the Conversion Price in effect
immediately prior to such

                                3

subdivision of the issuance of such dividend shall be proportionately
decreased and, in the event that the Company shall at any time combine the
outstanding shares of Common stock, the Conversion price in effect immediately
prior to such combination shall be proportionally increased, effective at the
close of business on the date of such subdivision, dividend or combination as
the case may be.
