judgment or for any mistake of fact or law; provided, that the Secured Party

designee's act, error or mistake constituted gross negligence or willful
misconduct. This power of attorney being coupled with an interest is irrevocable
while any Obligations shall remain unpaid.

Section shall survive the termination of this Agreement and the discharge of the
Debtor's other obligations hereunder.

         (a) The Debtor agrees to indemnify, reimburse and hold the Secured
Party and its successors, assigns, employees, officers, directors, agents,

any and all liabilities, obligations, damages, injuries, penalties, claims,
demands, actions, suits, judgments and any and all reasonable costs and expenses
(including, without limitation, reasonable attorneys' fees and expenses) of
whatsoever kind and nature imposed on, asserted against, or incurred by any of
the Indemnitees, in any way
<PAGE>

any of the terms hereof, or the preservation of any rights hereunder, or in any
way relating to or arising out of the manufacture, processing, ownership,
ordering, purchase, delivery, testing, control, lease, possession, operation or
other disposition or use of the Collateral by the Indemnitees (including,
without limitation, latent or other defects, whether or not discoverable);
provided, that the Debtor shall have no obligation to an Indemnitee hereunder to
the extent that such indemnified liabilities arise from the gross negligence or
willful misconduct of such Indemnitee. Upon written notice by any Indemnitee of
the assertion of such a liability, obligation, damage, injury, penalty, claim,
demand, action, judgment or suit, Debtor shall assume full responsibility for
the defense thereof. If any action, suit or proceeding arising from any of the
foregoing is brought against any Indemnitee, Debtor shall, if requested by such
Indemnitee, defend such action, suit or proceeding. Each Indemnitee shall,
unless any other Indemnitee has made the request described in the preceding
sentence and such request has been complied with, have the right to employ its
own counsel (or internal counsel) to investigate and control the defense of any
matter covered by the indemnity set forth in this Section, and the fees and
expenses of such counsel shall be paid by the Debtor; provided that, only to the
extent no conflict exists between and among the Indemnitees as reasonably

agrees to make the maximum
<PAGE>

contribution to the payment and satisfaction of such obligations that is
permissible under applicable law.

         (c) Survival. The obligations of the Debtor contained in this Section
shall survive the termination of this Agreement and the discharge of the
Debtor's other obligations hereunder. 10. Waivers. No act, omission or delay by
the Secured Party or course of dealing between the Secured Party and the Debtor
shall constitute a waiver of the rights and remedies of the Secured Party
hereunder. No single or partial waiver by the Secured Party of any Event of
Default or right or remedy which it may have shall operate as a waiver of any
other Event of Default, right or remedy or of the same Event of Default, right
or remedy on a future occasion. The Debtor hereby waives presentment, notice of
dishonor and protest of all instruments included in or evidencing any
Obligations or Collateral, and all other notices and demands whatsoever (except
as expressly provided herein).

"A" attached hereto and incorporated herein by reference, on the terms and
conditions set forth herein;

         NOW THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

1. Grant of Security Interest. As collateral security for the payment,
performance and observance of the Notes (the "Obligations"), the Debtor hereby
grants to the Secured Parties a security interest in; (a) any monies due the
Debtor arising out of an exempt offering by the Debtor of up to 92 units
consisting of convertible debentures and warrants offered to accredited
investors through the investment bank of J.P. Turner & Company and/or any other

trademarks), and (c) all of the Debtor's account receivables, inventory and

any and all additions thereto and replacements and proceeds thereof
(collectively, the "Collateral").

2. Representations, Warranties and Covenants. The Debtor represents, warrants
and covenants as follows:

         (a) The Debtor has full corporate power, authority and legal right to
grant a security interest in all of the Collateral pursuant to this Agreement,
and this Agreement constitutes the
<PAGE>

legal, valid and binding obligation of the Debtor, enforceable against it in
accordance with the terms.

         (b) No consent of any other party (including, without limitation,
stockholders or creditors of any of the Debtor) and no consent, authorization,
approval, or other action by, and no notice to or filing with, any governmental
authority or regulatory body is required and has not been obtained either (i)
for the grant of the security interest in the Collateral pursuant to this
Agreement, or (ii) for the execution, delivery or performance of this Agreement.

         (c) All filings, registrations and recordings necessary, appropriate or
reasonably requested by the Secured Parties to create, preserve, protect and
perfect the security interest granted by the Debtor to the Secured Parties
hereby in respect of the Collateral and required to be made on or before the
date hereof have been accomplished. The security interest granted to the Secured
Parties pursuant to this Agreement in and to the Collateral constitutes and
hereafter will constitute a perfected security interest therein (assuming fully
executed UCC-1 Financing Statements are properly filed with the Secretary of
State of the State of New York, County of New York, superior and prior to the
rights of all other persons therein, and subject to no other Liens (as such term
is defined below)).

         (d) The Debtor is, as of the date hereof, and, as to Collateral
acquired by it from time to time after the date hereof, will be, the owner of
the Collateral free from any Lien, except Permitted Liens (as such term is
defined below) or other right, title or interest of any persons other than the
Secured Parties, and the Debtor shall defend its ownership of the Collateral
against all claims and demands of all persons at any time claiming any interest
therein adverse to the Secured Parties.
<PAGE>

         (e) There is no financing statement or assignment on file in any
jurisdiction (or similar statement, notice of assignment or instrument of
registration under the law of any jurisdiction or the U.S. Patent and Trademark
Office) covering or purporting to cover any interest of any kind in the
Collateral, and the Debtor shall not execute or authorize to be filed in any
public office any financing statement (or similar statement, notice of
assignment or instrument of registration under the law of any jurisdiction)
relating to its ownership of the Collateral, except financing statements filed
or to be filed in respect of, and covering the security interests granted hereby
by the Debtor or granted by the Debtor to such holders.

         (f) The chief executive office of Debtor is located at 250 West 57th
Street, New York, New York. The Debtor shall not move its chief executive
offices until, (i) it has given to the Secured Party not less than fifteen (15)
days' prior written notice of its intention so to do (or, if move is within New
York County, such prior notice up to fifteen (15) days as can be reasonably
given), setting forth the new location (which shall be in the continental United
States of America) and such other information in connection therewith as the
Secured Party may reasonably request, and (ii) with respect to such new
location, the Debtor shall have taken all action reasonably satisfactory to the
Secured Parties to maintain the perfection and proof of the security interest of
the Secured Parties in the Collateral intended to be granted hereby, including,
without limitation, obtaining waivers of landlord's or warehouseman's liens with
respect to such new location.

         (g) The Debtor shall not change its corporate name until (i) it shall
have given to the Secured Parties not less than fifteen (15) days' prior written
notice of its intention so to do, clearly describing such new name and providing
such other information in connection therewith as the Secured Parties may
request, and (ii) with respect to such new name, the Debtor shall have
<PAGE>

taken all action reasonably satisfactory to the Secured Parties to maintain the
perfection and proof of the security interest of the Secured Parties in the
Collateral intended to be granted hereby.

         (h) All of the Collateral held on the date hereof and provided for
herein by the Debtor is located at (i) the Debtor's chief executive offices at
250 West 57th Street, New York, New York, 10019, (ii) the Debtor's sales office
located at 11601 Wilshire Boulevard, Los Angeles, (iii) the Debtor's co-location
facility located at 580 Winter Street, Waltham Massachusetts and the Connecticut
offices of Energenic, LLC, a software development company working exclusively
for the Company (collectively the "Collateral Location"). All Collateral now
held or subsequently acquired shall be kept at the Collateral Location or such
new location as the Debtor may establish, provided, however, that before
establishing such new location, (i) the Debtor shall have given the Secured
Parties no less than fifteen (15) days' prior notice thereof (or, if move is
within New York County, such prior notice up to fifteen (15) days as can be
reasonably given), clearly describing such new location (which shall be in the
continental United States of America) and shall have provided such other
information in connection therewith as the Secured Party may reasonably request,
and (ii) with respect to such new location, the Debtor shall have taken all
action reasonably satisfactory to the Secured Parties to maintain the perfection
and proof of the security interest in the Collateral intended to be granted
hereby, including, without limitation, obtaining waivers of landlord's or
warehouseman's liens with respect to such new location.

         (i) The Debtor will not assign, transfer, sell, lease or otherwise
dispose of any of the Collateral except in the ordinary course of business.
<PAGE>

         (j) The Debtor will use its ownership of the Collateral for lawful
purposes only, and in conformity with all applicable laws, ordinances and
regulations.

         (k) The Collateral is now and shall remain personal property, and the

without prior written notice to and consent of the Secured Parties and without
first making all arrangements, and delivering, or causing to be delivered, to
the Secured Parties all instruments and documents, including, without
limitation, waivers and subordination agreements by any landlords or mortgagees,
reasonably requested by and reasonably satisfactory in form and substance to the
Secured Parties to preserve and protect the security interest granted herein,
and to effectuate or maintain the priority thereof, against all persons.

         (l) The Debtor will maintain at its chief executive office proper books
of account and records in accordance with generally accepted accounting
principles applied on a consistent basis, and will deliver to the Secured
Parties the following:

concurrently:

         (a) Any of the Secured Parties may, at any time and from time to time,

<PAGE>

Collateral at the place of sale or other disposition, for cash and/or credit,

may resell such Collateral in accordance with the terms set forth above. The
Secured Parties may buy any Collateral at any public sale and, if any Collateral
is of a type customarily sold in a recognized market or is of the type which is

         (b) The Secured Parties may apply the cash proceeds actually received
from any sale or other disposition of Collateral to the reasonable expenses of

reasonable attorneys' fees and all reasonable legal, travel and other expenses

imposed by law to the holder of any subordinate security interest in the
Collateral known to the Secured Parties.

payment of the Obligations, any Collateral in or coming into the possession of
the Secured Parties or its agents, without notice to the Debtor and in such
manner as the Secured Parties may, in its reasonable discretion, determine
without regard to the existence or sufficiency of other collateral therefore.

         (d) Any of the Secured Parties, acting as permitted above, shall be
acting on behalf of itself as well as the other Secured Parties and shall hold

their agents as attorneys-in-fact of the Debtor, irrevocably and with power of
substitution, each with authority to:

         (a) endorse the name of the Debtor on any notes, acceptances, checks,
drafts, money orders, instruments or other evidences of Collateral that may come

and

         (g) do all other acts and things necessary or advisable in the sole
discretion of the Secured Parties to carry out and enforce this Agreement or the
Obligations. All acts done under the foregoing authorization are hereby ratified
and approved and neither the Secured Parties nor any designee or an agent
thereof shall be liable for any acts of commission or omission, for any error of
judgment or for any mistake of fact or law; provided, that the Secured Parties
shall not be relieved of liability to the extent its or its agent's or
designee's act, error or mistake constituted gross negligence or willful
misconduct. This power of attorney being coupled with an interest is irrevocable
while any Obligations shall remain unpaid.

7. Care of Collateral. Each of the Secured Parties shall have the duty to
exercise reasonable care in the custody and preservation of any Collateral in
their respective possession, which duty shall be fully satisfied if each such
Secured Party accord such Collateral treatment substantially the same as that
which they accord similar property owned by them, and, with respect to each such
Secured Party's custody and preservation of any of the Collateral in their
possession, the Debtor releases each such Secured Party from, and agree to
indemnify, defend, and hold harmless such Secured Parties with respect to, any
third party claims, causes of actions, and demands at any time arising out of or
with respect to each such Secured Party's custody and/or preservation of the
Collateral at any time in such Secured Party's possession, except that such
release and indemnity shall not be applicable to the extent that any such
claims, causes of actions, or demands have resulted from the respective Secured
Party's gross negligence or willful
<PAGE>

misconduct. Each such Secured Party's prior recourse to any Collateral shall not
constitute a condition of any demand, suit or proceeding for payment or
collection of the Obligations.

8. Expenses. So long as an Event of Default has occurred and is continuing, upon
demand, the Debtor will pay to the Secured Parties the amount of any and all
reasonable expenses, including the fees and expenses of its counsel and the fees

connection with (i) the collection of the Obligations, (ii) the administration
of this Agreement, (iii) the custody or preservation of, or the sale of,
collection from, or other realization upon, any of the Collateral, (iv) the
exercise or enforcement of any of the rights of the Secured Parties hereunder,
or (v) the failure of the Debtor to perform or observe any of the provisions
hereof. All amounts payable by the Debtor under this Section shall be due upon
demand and shall be part of the Obligations. The Debtor's obligations under this
Section shall survive the termination of this Agreement and the discharge of the
Debtor's other obligations hereunder.

9. Indemnification.

         (a) The Debtor agrees to indemnify, reimburse and hold each Secured
Party and its successors, assigns, employees, officers, directors, agents,
attorneys and servants (collectively, "Indemnities") harmless from and against
any and all liabilities, obligations, damages, injuries, penalties, claims,
demands, actions, suits, judgments and any and all reasonable costs and expenses
(including, without limitation, reasonable attorneys' fees and expenses) of
whatsoever kind and nature imposed on, asserted against, or incurred by any of
the Indemnitees, in any way relating to or arising out of this Agreement or in
any other way connected with the administration of the transactions contemplated
hereby or the enforcement of any of the terms hereof, or the preservation of any
rights hereunder, or in any way relating to or arising out of the manufacture,
<PAGE>

possession, operation or other disposition or use of the Collateral by the
Indemnitees (including, without limitation, latent or other defects, whether or
not discoverable); provided, that the Debtor shall have no obligation to an
Indemnitee hereunder to the extent that such indemnified liabilities arise from
the gross negligence or willful misconduct of such Indemnitee. Upon written
notice by any Indemnitee of the assertion of such a liability, obligation,
damage, injury, penalty, claim, demand, action, judgment or suit, Debtor shall
assume full responsibility for the defense thereof. If any action, suit or
proceeding arising from any of the foregoing is brought against any Indemnitee,
Debtor shall, if requested by such Indemnitee, defend such action, suit or
proceeding. Each Indemnitee shall, unless any other Indemnitee has made the
request described in the preceding sentence and such request has been complied
with, have the right to employ its own counsel (or internal counsel) to
investigate and control the defense of any matter covered by the indemnity set
forth in this Section, and the fees and expenses of such counsel shall be paid
by the Debtor; provided that, only to the extent no conflict exists between and
among the Indemnitees as reasonably determined by the Indemnitees, the Debtor
shall not be obligated to pay the fees and expenses or more than one counsel for
all Indemnitees as a group with respect to any such matter, action, suit or
proceeding.

         (b) Contribution. If and to the extent that the obligations of the
Debtor under this Section are unenforceable for any reason, the Debtor hereby
agrees to make the maximum contribution to the payment and satisfaction of such
obligations that is permissible under applicable law.

         (c) Survival. The obligations of the Debtor contained in this Section
shall survive the termination of this Agreement and the discharge of the
Debtor's other obligations hereunder.
<PAGE>

10. Waivers. No act, omission or delay by the Secured Parties or course of
dealing between the Secured Parties and the Debtor shall constitute a waiver of
the rights and remedies of the Secured Parties hereunder. No single or partial
waiver by the Secured Parties of any Event of Default or right or remedy which
it may have shall operate as a waiver of any other Event of Default, right or
remedy or of the same Event of Default, right or remedy on a future occasion.

instruments included in or evidencing any Obligations or Collateral, and all
