of the Warrant, upon the request of the holder hereof acknowledge in writing its
continuing  obligation  to afford to such holder any rights to which such holder
shall  continue  to be  entitled  after such  exercise  in  accordance  with the

for the  account of the  Company  or such  successor  person as may be  entitled
thereto, all amounts otherwise payable to the Company or such successor,  as the
case may be, on exercise of this Warrant pursuant to this Section 1.

     2. Procedure for Exercise.

     2.1 Delivery of Stock Certificates,  Etc., on Exercise.  The Company agrees
that the shares of Common Stock purchased upon exercise of this Warrant shall be
deemed to be issued to the Holder as the record  owner of such  shares as of the
close of business on the date on which this Warrant shall have been  surrendered
and payment made for such shares in accordance herewith.  As soon as practicable
after the exercise of this  Warrant in full or in part,  and in any event within
three (3) business days  thereafter,  the Company at its expense  (including the
payment by it of any applicable issue taxes) will cause to be issued in the name
of and  delivered to the Holder,  or as such Holder (upon payment by such Holder
of any  applicable  transfer  taxes) may direct in  compliance  with  applicable
securities  laws,  a  certificate  or  certificates  for the  number of duly and
validly issued,  fully paid and  nonassessable  shares of Common Stock (or Other
Securities)  to which such Holder shall be entitled on such  exercise,  plus, in
lieu of any fractional  share to which such holder would  otherwise be entitled,
cash equal to such fraction multiplied by the then Fair Market Value of one full
share, together with any other stock or other securities and property (including
cash,  where  applicable)  to which such Holder is entitled  upon such  exercise
pursuant to Section 1 or otherwise.

     2.2  Exercise.  Payment may be made either (i) in cash or by  certified  or
official bank check payable to the order of the Company equal to the  applicable
aggregate  Exercise Price, (ii) by delivery of the Warrant,  or shares of Common
Stock and/or Common Stock  receivable upon exercise of the Warrant in accordance
with  Section  (b)  below,  or (iii) by a  combination  of any of the  foregoing
methods,  for the number of Common Shares  specified in such Exercise Notice (as
such  exercise  number shall be adjusted to reflect any  adjustment in the total
number of shares of Common  Stock  issuable  to the Holder per the terms of this
Warrant)  and the Holder  shall  thereupon  be entitled to receive the number of
duly authorized,  validly issued, fully-paid and non-assessable shares of Common
Stock (or Other Securities)  determined as provided herein.  Notwithstanding any
provisions  herein to the  contrary,  if the Fair  Market  Value of one share of
Common Stock is greater than the Exercise  Price (at the date of  calculation as
set forth below),  in lieu of exercising  this Warrant for cash,  the Holder may
elect to receive shares equal to the value (as determined below) of this Warrant
(or the portion  thereof  being  exercised)  by surrender of this Warrant at the
principal  office of the Company  together with the properly  endorsed  Exercise
Notice in which event the  Company  shall issue to the Holder a number of shares
of Common Stock computed using the following formula:

                                       3
<PAGE>

 X=Y            (A-B)
               ---------
                  A

 Where X =   the number of shares of Common Stock to be issued to the Holder

 Y =         the number of shares of Common Stock purchasable
             under the Warrant or, if only a portion of the
             Warrant is being exercised, the portion of the
             Warrant being exercised (at the date of such
             calculation)

 A =         the Fair Market  Value of one share of the Company's Common Stock
             (at the date of such calculation)

 B =         Exercise Price (as adjusted to the date of such calculation)

     3. Effect of Reorganization, Etc.; Adjustment of Exercise Price.

     3.1 Reorganization, Consolidation, Merger, Etc. In case at any time or from
time to time,  the Company shall (a) effect a  reorganization,  (b)  consolidate
with or merge into any other person, or (c) transfer all or substantially all of
its  properties  or  assets to any other  person  under any plan or  arrangement
contemplating  the  dissolution  of the Company,  then,  in each such case, as a
condition  to the  consummation  of  such a  transaction,  proper  and  adequate
provision  shall be made by the Company  whereby the Holder of this Warrant,  on
the exercise hereof as provided in Section 1 at any time after the  consummation
of such  reorganization,  consolidation  or merger or the effective date of such
dissolution,  as the case may be, shall receive, in lieu of the Common Stock (or
Other  Securities)  issuable on such exercise prior to such consummation or such
effective date, the stock and other securities and property  (including cash) to
which  such  Holder  would  have  been  entitled  upon such  consummation  or in
connection  with such  dissolution,  as the case may be, if such  Holder  had so
exercised  this  Warrant,  immediately  prior  thereto,  all  subject to further
adjustment thereafter as provided in Section 4.

     3.2 Dissolution.  In the event of any dissolution of the Company  following
the  transfer  of all or  substantially  all of its  properties  or assets,  the
Company,  concurrently  with any  distributions  made to  holders  of its Common
Stock,  shall at its expense  deliver or cause to be delivered to the Holder the
stock and other  securities  and property  (including  cash,  where  applicable)
receivable  by the Holder of the  Warrant  pursuant to Section  3.1,  or, if the
Holder shall so instruct the Company,  to a bank or trust  company  specified by
the Holder and having its  principal  office in New York,  NY as trustee for the
Holder of the Warrant (the "Trustee").

     3.3 Continuation of Terms. Upon any reorganization,  consolidation,  merger
or transfer (and any  dissolution  following  any transfer)  referred to in this
Section 3, this  Warrant  shall  continue in full force and effect and the terms
hereof  shall be  applicable  to the  shares of stock and other  securities  and
property  receivable on the exercise of this Warrant after the  consummation  of
such   reorganization,   consolidation  or  merger  or  the  effective  date  of

                                       4
<PAGE>

dissolution  following  any such  transfer,  as the case  may be,  and  shall be
binding upon the issuer of any such stock or other securities, including, in the
case of any such transfer,  the person acquiring all or substantially all of the
properties  or assets of the  Company,  whether  or not such  person  shall have
expressly  assumed  the terms of this  Warrant as  provided in Section 4. In the
event  this  Warrant  does not  continue  in full  force  and  effect  after the
consummation of the transactions described in this Section 3, then the Company's
securities and property  (including  cash, where  applicable)  receivable by the
Holders  of  the  Warrant  will  be  delivered  to  Holder  or  the  Trustee  as
contemplated by Section 3.2.

     4.  Extraordinary  Events  Regarding  Common  Stock.  In the event that the
Company shall (a) issue  additional  shares of the Common Stock as a dividend or
other  distribution on outstanding  Common Stock,  (b) subdivide its outstanding
shares of Common  Stock,  or (c)  combine its  outstanding  shares of the Common
Stock into a smaller  number of shares of the Common  Stock,  then, in each such
event,  the Exercise  Price  shall,  simultaneously  with the  happening of such
event,  be adjusted by multiplying  the then Exercise  Price by a fraction,  the
numerator  of which  shall be the number of shares of Common  Stock  outstanding
immediately prior to such event and the denominator of which shall be the number
of shares of Common  Stock  outstanding  immediately  after such event,  and the
product so obtained shall  thereafter be the Exercise Price then in effect.  The
Exercise Price, as so adjusted,  shall be readjusted in the same manner upon the
happening of any successive  event or events described herein in this Section 4.
The  number of shares of Common  Stock  that the  holder of this  Warrant  shall
thereafter,  on the  exercise  hereof as  provided  in Section 1, be entitled to
receive shall be increased to a number  determined by multiplying  the number of
shares of Common  Stock that would  otherwise  (but for the  provisions  of this
Section 4) be issuable on such exercise by a fraction of which (a) the numerator
is the  Exercise  Price that would  otherwise  (but for the  provisions  of this
Section 4) be in effect, and (b) the denominator is the Exercise Price in effect
on the date of such exercise.

     5.  Certificate  as to  Adjustments.  In  each  case of any  adjustment  or
readjustment in the shares of Common Stock (or Other Securities) issuable on the
exercise of the  Warrant,  the Company at its expense  will  promptly  cause its
Chief Financial Officer or other appropriate designee to compute such adjustment
or  readjustment  in  accordance  with the terms of the  Warrant  and  prepare a
certificate  setting forth such adjustment or readjustment and showing in detail
the facts upon which such  adjustment  or  readjustment  is based,  including  a

additional shares of Common Stock (or Other Securities) issued or sold or deemed
to have been issued or sold,  (b) the number of shares of Common Stock (or Other
Securities) outstanding or deemed to be outstanding,  and (c) the Exercise Price
and the number of shares of Common  Stock to be received  upon  exercise of this
Warrant,  in effect  immediately prior to such adjustment or readjustment and as
adjusted or readjusted as provided in this Warrant.  The Company will  forthwith
mail a copy of each  such  certificate  to the  holder  of the  Warrant  and any
Warrant agent of the Company (appointed pursuant to Section 11 hereof).

will at all times on and after  August  28,  2004  reserve  and keep  available,
solely for  issuance  and  delivery on the  exercise of the  Warrant,  shares of

the Warrant.

endorsement  in  the  form  of  Exhibit  B  attached  hereto  (the   "Transferor
Endorsement  Form") and together with evidence  reasonably  satisfactory  to the
Company  demonstrating  compliance with applicable  securities laws, which shall

from the  registration  requirements  of applicable  securities  laws,  and with
payment by the  Transferor  of any  applicable  transfer  taxes)  will issue and

delivery of an indemnity agreement or security  reasonably  satisfactory in form

Warrant on an exercise date, in connection  with that number of shares of Common
Stock  which would be in excess of the sum of (i) the number of shares of Common
Stock  beneficially  owned by the Holder and its affiliates on an exercise date,
and (ii) the number of shares of Common Stock issuable upon the exercise of this
Warrant with respect to which the determination of this proviso is being made on
an exercise date,  which would result in beneficial  ownership by the Holder and
its affiliates of more than 4.99% of the  outstanding  shares of Common Stock of
the Company on such date.  For the  purposes  of the proviso to the  immediately
preceding sentence,  beneficial ownership shall be determined in accordance with

the  Holder  of this  Warrant  shall be  mailed  by first  class  registered  or
certified mail,  postage prepaid,  at such address as may have been furnished to
the Company in writing by such Holder or, until any such Holder furnishes to the
Company an  address,  then to, and at the  address  of, the last  Holder of this
Warrant who has so furnished an address to the Company.

     14. Voluntary Adjustment by the Company. The Company may at any time during
the term of this Warrant  reduce the then current  Exercise  Price to any amount

Company.

     15. Miscellaneous. This Warrant and any term hereof may be changed, waived,
discharged  or terminated  only by an instrument in writing  signed by the party
against which  enforcement of such change,  waiver,  discharge or termination is
sought.  This Warrant shall be governed by and construed in accordance  with the
laws of State of New York without regard to principles of conflicts of laws. Any
action brought concerning the transactions contemplated by this Warrant shall be
brought only in the state courts of New York or in the federal courts located in
the state of New York;  provided,  however,  that the Holder may choose to waive
this  provision  and  bring  an  action  outside  the  state  of New  York.  The
individuals  executing  this Warrant on behalf of the Company agree to submit to
the  jurisdiction  of such courts and waive trial by jury. The prevailing  party
shall be entitled to recover from the other party its reasonable attorney's fees
and  costs.  In the event  that any  provision  of this  Warrant  is  invalid or
unenforceable  under any applicable  statute or rule of law, then such provision
shall be deemed  inoperative  to the extent that it may conflict  therewith  and
shall be deemed  modified to conform  with such statute or rule of law. Any such
provision  which  may prove  invalid  or  unenforceable  under any law shall not
affect the validity or  enforceability  of any other  provision of this Warrant.
The headings in this Warrant are for purposes of reference  only,  and shall not
limit  or  otherwise  affect  any  of  the  terms  hereof.   The  invalidity  or
unenforceability  of any provision hereof shall in no way affect the validity or
enforceability  of any other provision  hereof.  The Company  acknowledges  that
legal counsel  participated in the  preparation of this Warrant and,  therefore,
stipulates  that the rule of  construction  that  ambiguities are to be resolved
against the drafting  party shall not be applied in the  interpretation  of this
Warrant to favor any party against the other party.

the Documents or any documents, instruments or agreements referred to therein or
otherwise, and in connection with any other indebtedness, obligations or
liabilities of any Assignor to Laurus, whether now existing or hereafter
arising, direct or indirect, liquidated or unliquidated, absolute or contingent,

guaranty, instrument or otherwise, in each case, irrespective of the
genuineness, validity, regularity or enforceability of such Obligations, or of
any instrument evidencing any of the Obligations or of any collateral therefor
or of the existence or extent of such collateral, and irrespective of the
allowability, allowance or disallowance of any or all of the Obligations in any
case commenced by or against any Assignor under Title 11, United States Code,
including, without limitation, obligations or indebtedness of each Assignor for

Assignor and the policies delivered to Laurus. If any such Assignor fails to do
so, Laurus may procure such insurance and the cost thereof shall be promptly
reimbursed by the Assignors, jointly and severally, and shall constitute
Obligations;

     (i) it will at all reasonable times allow Laurus or Laurus' representatives
free access to and the right of inspection of the Collateral;

     (j) such Assignor (jointly and severally with each other Assignor) hereby
indemnifies and saves Laurus harmless from all loss, costs, damage, liability
and/or expense, including reasonable attorneys' fees, that Laurus may sustain or
incur to enforce payment, performance or fulfillment of any of the Obligations
and/or in the enforcement of this Master Security Agreement or in the
prosecution or defense of any action or proceeding either against Laurus or any
Assignor concerning any matter growing out of or in connection with this Master
Security Agreement, and/or any of the Obligations and/or any of the Collateral
except to the extent caused by Laurus' own gross negligence or willful
misconduct (as determined by a court of competent jurisdiction in a final and
nonappealable decision).

                                       3

     4. The occurrence of any of the following events or conditions shall
constitute an "Event of Default" under this Master Security Agreement:

     (a) Breach of any covenant, warranty, representation or statement made or

misleading in any material respect when made or furnished, and if subject to
cure, shall not be cured for a period of fifteen (15) days;

     (b) the loss, theft, substantial damage, destruction, sale or encumbrance

     (i) such loss is covered by insurance proceeds which are used to replace
the item or repay Laurus; or

     (ii) said levy, seizure or attachment does not secure indebtedness in
excess of $100,000 and such levy, seizure or attachment has not been removed or
otherwise released within ten (10) days of the creation or the assertion
thereof;

     (b) any Assignor shall become insolvent, cease operations, dissolve,
terminate our business existence, make an assignment for the benefit of
creditors, suffer the appointment of a receiver, trustee, liquidator or
custodian of all or any part of Assignors' property;

     (c) any proceedings under any bankruptcy or insolvency law shall be
commenced by or against any Assignor and if commenced against any Assignor shall

     (d) the Company shall repudiate, purport to revoke or fail to perform any
or all of its obligations under any Note (after passage of applicable cure
period, if any); or

     (e) an Event of Default shall have occurred under and as defined in any
Document.

     5. Upon the occurrence of any Event of Default and at any time thereafter,
Laurus may declare all Obligations immediately due and payable and Laurus shall
have the remedies of a secured party provided in the Uniform Commercial Code as
in effect in the State of New York, this Agreement and other applicable law.
Upon the occurrence of any Event of Default and at any time thereafter, Laurus
will have the right to take possession of the Collateral and to maintain such
possession on our premises or to remove the Collateral or any part thereof to
such other premises as Laurus may desire. Upon Laurus' request, each of the
Assignors shall assemble or cause the Collateral to be assembled and make it
available to Laurus at a place designated by Laurus. If any notification of
intended disposition of any Collateral is required by law, such notification, if
mailed, shall be deemed properly and reasonably given if mailed at least ten
(10) days before such disposition, postage prepaid, addressed to any Assignor
either at such Assignor's address shown herein or at any address appearing on
Laurus' records for such Assignor. Any proceeds of any disposition of any of the

                                       4
<PAGE>

Collateral shall be applied by Laurus to the payment of all expenses in
connection with the sale of the Collateral, including reasonable attorneys' fees
and other legal expenses and disbursements and the reasonable expense of
retaking, holding, preparing for sale, selling, and the like, and any balance of
such proceeds may be applied by Laurus toward the payment of the Obligations in
such order of application as Laurus may elect, and each Assignor shall be liable
for any deficiency. For the avoidance of doubt, following the occurrence and
during the continuance of an Event of Default, Laurus shall have the immediate
right to withdraw any and all monies contained in the Restricted Account and
apply same to the repayment of the Obligations (in such order of application as
Laurus may elect).

     6. If any Assignor defaults in the performance or fulfillment of any of the
terms, conditions, promises, covenants, provisions or warranties on such
Assignor's part to be performed or fulfilled under or pursuant to this Master
Security Agreement, Laurus may, at its option without waiving its right to
enforce this Master Security Agreement according to its terms, immediately or at
any time thereafter and without notice to any Assignor, perform or fulfill the
same or cause the performance or fulfillment of the same for each Assignor's
joint and several account and at each Assignor's joint and several cost and
expense, and the cost and expense thereof (including reasonable attorneys' fees)
shall be added to the Obligations and shall be payable on demand with interest
thereon at the highest rate permitted by law, or, at Laurus' option, debited by
Laurus from the Restricted Account referred to in the Restricted Account
Agreement.

     7. Each Assignor appoints Laurus, any of Laurus' officers, employees or any
other person or entity whom Laurus may designate as our attorney, with power to
execute such documents in each of our behalf and to supply any omitted
information and correct patent errors in any documents executed by any Assignor
or on any Assignor's behalf; to file financing statements against us covering
the Collateral (and, in connection with the filing of any such financing
statements, describe the Collateral as "all assets and all personal property,
whether now owned and/or hereafter acquired" (or any substantially similar
variation thereof)); to sign our name on public records; and to do all other
things Laurus deem necessary to carry out this Master Security Agreement. Each
Assignor hereby ratifies and approves all acts of the attorney and neither
Laurus nor the attorney will be liable for any acts of commission or omission,
nor for any error of judgment or mistake of fact or law other than gross
negligence or willful misconduct (as determined by a court of competent
jurisdiction in a final and non-appealable decision). This power being coupled
with an interest, is irrevocable so long as any Obligations remains unpaid.

     8. No delay or failure on Laurus' part in exercising any right, privilege
or option hereunder shall operate as a waiver of such or of any other right,
privilege, remedy or option, and no waiver whatever shall be valid unless in
writing, signed by Laurus and then only to the extent therein set forth, and no
waiver by Laurus of any default shall operate as a waiver of any other default
or of the same default on a future occasion. Laurus' books and records
containing entries with respect to the Obligations shall be admissible in
evidence in any action or proceeding, shall be binding upon each Assignor for
the purpose of establishing the items therein set forth and shall constitute
prima facie proof thereof. Laurus shall have the right to enforce any one or
more of the remedies available to Laurus, successively, alternately or
concurrently. Each Assignor agrees to join with Laurus in executing financing
statements or other instruments to the extent required by the Uniform Commercial
Code in form satisfactory to Laurus and in executing such other documents or
instruments as may be required or deemed necessary by Laurus for purposes of
affecting or continuing Laurus' security interest in the Collateral.

                                       5

     9. This Master Security Agreement shall be governed by and construed in

orally. All of the rights, remedies, options, privileges and elections given to
Laurus hereunder shall inure to the benefit of Laurus' successors and assigns.
The term "Laurus" as herein used shall include Laurus, any parent of Laurus',
any of Laurus' subsidiaries and any co-subsidiaries of Laurus' parent, whether
now existing or hereafter created or acquired, and all of the terms, conditions,
promises, covenants, provisions and warranties of this Agreement shall inure to
the benefit of and shall bind the representatives, successors and assigns of
each Assignor and each of the foregoing. Laurus and each Assignor hereby (a)
waive any and all right to trial by jury in litigation relating to this
Agreement and the transactions contemplated hereby and each Assignor agrees not
to assert any counterclaim in such litigation, (b) submit to the nonexclusive
