     SECTION 1. THE SECURITY INTERESTS. In order (i) to secure the due and

the performance of all the obligations of Debtor contained herein (all of the
foregoing are hereinafter called the "Obligations"), which Obligations shall not
exceed in the aggregate the sum of $4,500,000, Debtor hereby grants to Secured

<PAGE>
     The security interests granted pursuant to this Section 1 (the "Security
Interests") are granted as security only and shall not subject Secured Party to,
or transfer to Secured Party, or in any way affect or modify, any obligation or
liability of Debtor under any of the Collateral or any transaction which gave
rise thereto.

     For avoidance of doubt it is expressly understood and agreed that the
Collateral does not include, inter alia, patents, applications for patents,
trademarks, trade names, service marks, registrations of trademarks and service
marks, copyrights, blueprints, designs, engineering drawings and contracts,
proprietary information, product lines, research and development, or any other
form of intellectual property.

     SECTION 2. FILING; FURTHER ASSURANCES. Debtor hereby agrees to do all acts
that the Secured Party deems necessary or desirable to protect the Security
Interests or to otherwise carry out the provisions of this Security Agreement,
including, but not limited to, the execution of financing, continuation and
amendment statements and similar instruments that describe or indicate the
Collateral and which contain any other information required by Part 5 of Article
9 of the UCC for the sufficiency or filing office acceptance of any financing
statement, continuation statement or amendment. The Debtor appoints Secured
Party as the Debtor's attorney irrevocable to do all acts that the Debtor may be
required to do under this Security Agreement. Debtor shall be liable for the
payment of all charges, fees and expenses, including any documentary stamp taxes
that may be due, in connection with this Security Agreement, the filing of the
aforementioned financing, continuation and amendment statements, and the payment
of the Obligations. In the event documentary stamp taxes are not initially paid
hereunder and such taxes are later required to be paid in order to enforce the
Security Interests granted hereunder, any Secured Party may pay such taxes and
accrued interest and penalties and Debtor shall indemnify such Secured Party
from and against such taxes, interest and penalties. Further, in any future
action in which any Secured Party seeks enforcement of the Security Interests,
Debtor expressly waives any rights it may have to assert such nonpayment of the
documentary stamp taxes as an affirmative defense against such enforcement.
Debtor shall, during normal business hours and from time to time, allow the
Secured Party, by or through any of its officers or employees to examine or
inspect the Collateral and make extracts from Debtor's books and records.

     SECTION 3. REPRESENTATIONS, WARRANTIES AND COVENANTS.

         (a) Chief Executive Office/Location of Records/Change of Name/Change of
State of Incorporation. Debtor's chief executive office is located at the
address set forth in Section 8 below and records relating to Debtor's accounts
are kept at such address. Debtor has no other place of business except as set
forth on Schedule I. Debtor agrees to provide Secured Party with sixty (60) days
prior written notice of any change in the name of Debtor or the location of
Debtor's chief executive office. Debtor further agrees to provide Secured Party
with sixty (60) days prior written notice of any change in the state of Debtor's
incorporation.

         (b) Location of Collateral. All Collateral is located at the Debtor's
principal place of business set forth in Section 8 and in such other locations,
if any, set forth on Schedule I. None of the Collateral shall be removed from
such locations except in connection with sales in the ordinary course of
business.

                                     - 2 -
<PAGE>
         (c) Absence of Liens, Disposition of Collateral. To the best of
Debtor's knowledge, Debtor is the owner of the Collateral free from all
encumbrances. Except as otherwise provided herein, Debtor will not pledge,
mortgage or create or suffer to exist a lien, security interest or other
encumbrance in the Collateral in favor of any person. Further, Debtor will not
sell or transfer the Collateral or any interest therein without the prior
written consent of the Secured Party, except in the ordinary course of business.

         (d) Maintenance of Collateral. The Debtor covenants and agrees to
preserve the Collateral for the benefit of Secured Party and the Debtor agrees
that it will not sell, lease or otherwise dispose of any item of the Collateral
except for the sale of inventory in the ordinary course of business or the
replacement of collateral in the ordinary course of business.

         (e) Insurance. Debtor shall maintain insurance covering the Collateral
against such risks, with such insurers, in such form, and in such amounts as
shall from time to time be reasonably required by Secured Party and, in any
event, against such risks and with such limits as is consistent with industry
practice. All insurance policies shall be written so as to be payable in the
event of loss to Secured Party and shall provide for thirty (30) days' written
notice to Secured Party of cancellation or modification. At the request of
Secured Party and after an Event of Default (as defined below), all insurance
policies shall be furnished to and held by Secured Party. Prior to default,
Debtor shall furnish to Secured Party certificates of insurance reasonably
satisfactory to Secured Party. Debtor hereby conditionally assigns to Secured
Party return premiums, dividends and other amounts which may be or become due
upon cancellation of any such policies for any reason whatsoever and directs the
insurers to pay Secured Party any sums so due following an Event of Default.
Following an Event of Default, the Secured Party is hereby irrevocably appointed
as attorney in fact to collect return premiums, dividends and other amounts due
on any insurance policy and the proceeds of such insurance, to settle any claims
with the insurers in the event of loss or damage, to endorse settlement drafts
and to cancel, assign or surrender any insurance policies.

         (f) Obligations. Debtor hereby warrants and represents that as of the
date of this Security Agreement, the Obligations owed collectively to the
Secured Parties do not exceed $4,500,000.

     SECTION 4. EVENTS OF DEFAULT. Debtor shall be in default under this
Security Agreement upon the occurrence of any one of the following events (each
such event is herein referred to as an "Event of Default"):

         (a) default by Debtor in the due observance or performance of the
covenants contained in Section 3 of or elsewhere in this Security Agreement; or

         (b) any representation or warranty or statement of fact made to
Secured Party at any time by Debtor is false or misleading in any material
respect; or

         (c) the occurrence of a default or event of default under any of the
Settlement Agreements.

     SECTION 5.  REMEDIES UPON EVENT OF DEFAULT.

         (a) If any Event of Default shall have occurred, any Secured Party may
declare its portion of the Obligations to be immediately due and payable and
exercise all the rights and remedies of a secured party under the UCC (whether
or not the UCC is in effect in the jurisdiction where such rights and remedies
are exercised) and, in addition, any Secured Party may, without being required
to give any notice, except as herein provided or as may be required by mandatory
provisions of law, sell the Collateral, or any part thereof, at public or
private sale for cash, upon credit or for future delivery, and at such price or
prices as such Secured Party may deem satisfactory.

         (b) Any Secured Party may require Debtor to assemble all or any part of
the Collateral and make it available to such Secured Party at a place to be
designated by such Secured Party which is reasonably convenient. Any holder of
an Obligation may be the purchaser of any or all of the Collateral so sold at
any public sale (and, if the Collateral is of a type customarily sold in a
recognized market or is of a type which is the subject of widely distributed
standard price quotations, at any private sale) and thereafter hold the same
absolutely, free from any right or claim of whatsoever kind. Upon any such sale
such Secured Party shall have the right to deliver, assign and transfer to the
purchaser thereof the Collateral so sold. Each purchaser at any such sale shall
hold the Collateral so sold absolutely, free from any claim or right of
whatsoever kind, including any equity or right of redemption of Debtor.

         (c) A Secured Party shall give Debtor at least twenty (20) days' prior
written notice of its intention to make any such public or private sale. Secured
Parties and Debtor agree that such notice constitutes "reasonable notification"
within the meaning of the UCC. Such notice, in case of a public sale, shall
state the time and place fixed for such sale. Such notice, in case of a private
sale or disposition, shall state the time after which any private sale or other
intended disposition is to be made. All notices shall otherwise comply with the
terms of the UCC.

         (d) Any such public sale shall be held at such time or times within
ordinary business hours and at public or private place or places as a Secured
Party may fix in the notice of such sale. At any public or private sale, the
Collateral may be sold in one lot as an entirety or in separate parcels, as such
Secured Party may determine. Such Secured Party shall not be obligated to make
such sale pursuant to any such notice. Such Secured Party may, without notice or
publication, adjourn any public or private sale or cause the same to be
adjourned from time to time by announcement at the time and place fixed for the
sale, and such sale may be made at any time or place to which the same may be
adjourned. In case of any sale of all or any part of the Collateral on credit or
for future delivery, the Collateral so sold may be retained by such Secured
Party until the selling price is paid by the purchaser thereof, but such Secured
Party shall not incur any liability in case of the failure of such purchaser to
take up and pay for the Collateral so sold and, in case of any such failure,
such Collateral may again be sold upon like notice.

         (e) Any Secured Party, instead of exercising the power of sale herein
conferred upon it, may proceed by a suit or suits at law or in equity to
foreclose the Security Interests and sell the Collateral, or any portion
thereof, under a judgment or decree of a court or courts of competent
jurisdiction.

                                     - 4 -
<PAGE>
         (f) Secured Party may take any other action that Secured Party deems
necessary or desirable to protect the Collateral or the Security Interests.

         (g) All rights and remedies contained herein shall be separate and
cumulative and in addition to all other rights and remedies available to a
secured party under applicable law, and the exercise of one shall not in any way
limit or prejudice the exercise of any other such rights or remedies.

     SECTION 6.  APPLICATION OF PROCEEDS.  The proceeds of any sale of, or other
realization upon, all or any part of the Collateral shall be applied in the
following order of priorities:

         (a) first, to pay the expenses of such sale or other realization,
including out-of-pocket expenses of Secured Party and reasonable fees and
expenses of its agents and counsel, and all expenses, liabilities and advances
incurred or made by Secured Party in connection therewith;

         (b) second, to the payment of the Obligations owed to each of the
Secured Parties in proportion to the amount of the outstanding Obligations owed
to each of the Secured Parties at the time of such payment; and

         (c) finally, unless applicable law otherwise provides, to pay to
Debtor, or its successors or assigns, or as a court of competent jurisdiction
may direct, any surplus then remaining from such proceeds.

     SECTION 7. TERMINATION OF SECURITY INTERESTS; RELEASE OF COLLATERAL. Upon
the repayment and performance in full of all the Obligations, the Security
Interests shall terminate and all rights to the Collateral shall revert to
Debtor. Upon any such termination of the Security Interests or release of
Collateral, Secured Party will, at Debtor's expense to the extent permitted by
law, execute and deliver to Debtor such documents as Debtor shall reasonably
request to evidence the termination of the Security Interests or the release of
such Collateral, as the case may be.

     SECTION 8. NOTICES. All notices and correspondence, hereunder shall be in
writing and sent by certified or registered mail, return receipt request, or by

         THIS SUBSCRIPTION AGREEMENT (this "AGREEMENT") is made as of the date

                              W I T N E S S E T H:

         WHEREAS, the Company is engaged in a private offering (the "OFFERING")
of the Company's common stock, par value $.001 per share (the "COMMON STOCK");
and

         WHEREAS, the Company desires to issue up to 2,200,000 shares of Common

         WHEREAS, the Subscriber desires to purchase that number of shares of

         NOW, THEREFORE, in consideration of the premises and the mutual

hereby agree as follows:

1.       SUBSCRIPTION FOR COMMON STOCK AND REPRESENTATIONS BY SUBSCRIBER.

Subscriber may not be able to liquidate its investment; (iv) the Subscriber
could sustain the loss of its entire investment; and (v) the Company has not
paid any dividends on its Common Stock since inception and does not anticipate

"accredited investor" as such term is defined in Rule 501 of Regulation D
promulgated under the Securities Act of 1933, as amended (the "ACT"), as

and all attachments to it and has received or obtained via EDGAR the Company's
Annual Report on Form 10-K for the year ended December 31, 2000, and the

and hereby represents that the Subscriber has been furnished by the Company
during the course of this transaction with all information regarding the Company
that the Subscriber, its investment advisor, attorney and/or accountant has
requested, has been afforded the opportunity to ask questions of and receive
answers from duly authorized officers or other representatives of the Company
concerning the terms and conditions of the Offering, and has received any
additional information regarding the Company or the securities offered in the
Offering that the Subscriber has requested.

         1.6      (a) The Subscriber has relied solely upon the information
provided by the Company in this Agreement and the Company's filings with the
Commission under Section 13(a) of the Securities Exchange Act of 1934, as
amended (the "EXCHANGE ACT") in making the decision to invest in the Common
Stock. To the extent necessary, the Subscriber has retained, at its sole

any "material nonpublic information" to any Subscriber, as such is defined under
applicable law, rule and regulation.

                  (b) The Subscriber represents that no Common Stock has been
offered or sold to it by means of any form of general solicitation or general
advertising, and in connection with the Offering the Subscriber did not: (i)

         1.7      The Subscriber hereby acknowledges that the offering of the
Common Stock has not been reviewed by the United States Securities and Exchange
Commission (the "SEC" or the "COMMISSION") or any state securities regulatory
authority, since the Offering is intended to be exempt from the registration
requirements of Section 5 of the Act pursuant to Regulation D promulgated under
the Act.

         1.8      The Subscriber understands that the Common Stock has not been
registered under the Act by reason of a claimed exemption under the provisions
of the Act that depends, in part, upon the Subscriber's investment intention. In
this regard, the Subscriber hereby represents that the Subscriber is purchasing
the Common Stock for the Subscriber's own account for investment and has no
current arrangements or understandings for the resale or distribution to others
and will only resell the Common Stock pursuant to an effective registration
statement or exemption therefrom. The Subscriber, if an entity, also represents
that it was not formed for the purpose of purchasing the Common Stock.

         1.9      The Subscriber understands that, although there currently is a
public market for the Common Stock, the securities are "restricted securities"
within the meaning of Rule 144 promulgated under the Act ("RULE 144") and,
therefore, the Subscriber shall not sell or otherwise transfer the shares of
Common Stock unless they are registered under the Act or unless an exemption
from such registration is available. The Subscriber understands and hereby
acknowledges that the Company is under no obligation to register the Common
Stock under the Act or any state securities or "blue sky" laws other than as set
forth in Article 5.

         1.10     The Subscriber consents to the placement of a legend on any
certificate or other document evidencing the Common Stock, to the effect that
such Common Stock has not been registered under the Act or any state securities
or "blue sky" laws and setting forth or referring to the restrictions on
transferability and sale thereof contained in this Agreement or otherwise
mandated by law. The Subscriber is aware that the Company will make a notation
in its records with respect to the restrictions on the transferability of the
Common Stock.

         1.11     The Subscriber understands that the Company reserves the
unrestricted right, without further documentation or agreement on the part of
the Subscriber, to reject or limit any subscription, to accept subscriptions for
fractional shares and, subject to Section 3.1, to close the Offering to the
Subscriber at any time.

         1.12     The Subscriber hereby represents that the address of the
Subscriber furnished by Subscriber on the signature page hereof is the
Subscriber's principal residence if Subscriber is an individual or its principal
business address if it is a corporation or other entity.

         1.13     The Subscriber represents that the Subscriber has full power,
authority (corporate, statutory and otherwise) and capacity to execute and
deliver this Agreement and to purchase the Common Stock. This Agreement
constitutes the legal, valid and binding obligation of the Subscriber,
enforceable against the Subscriber in accordance with its terms, subject to laws
of general application relating to bankruptcy, insolvency and the relief of
debtors and rules of law governing specific performance, injunctive relief or
other equitable remedies and to limitations of public policy.

         1.14     If the Subscriber is a corporation, partnership, limited
liability company, trust, employee benefit plan, individual retirement account,
Keogh Plan, or other entity (i) it is authorized and qualified to become an
investor in the Company and the person signing this Agreement on behalf of such
entity has been duly authorized by such entity to do so and (ii) it is duly
organized, validly existing and, if a corporation, in good standing under the
laws of the jurisdiction of its organization.

         1.15     The Subscriber acknowledges that if he or she is a Registered
Representative of an NASD (as defined in Section 2.6) member firm, he or she
must give such firm the notice required by the NASD Rules of Fair Practice,
receipt of which must be acknowledged by such firm in Section 7.4 below.

         1.16     The Company acknowledges and agrees that to its knowledge each
of the Subscribers is acting solely in the capacity of an arm's length purchaser
with respect to this Agreement and the transactions contemplated hereby and that

<PAGE>
                  (a) cause such registration, and any necessary qualification,
exemption or compliance under all applicable state securities laws, to remain

therein (in the case of the prospectus, in the light of the circumstances under
which they were made) not misleading;

                  (c) make every commercially reasonable effort to obtain the
withdrawal of any order suspending the effectiveness of any Registration
Statement at the earliest possible time;

                  (d) furnish to each Holder, without charge, at least one copy

                  (f) during the Registration Period, deliver to each Holder,
without charge, (i) as soon as practicable one copy of the following documents:
(A) its annual report to its stockholders, if any (which annual report shall
contain financial statements audited in accordance with generally accepted
accounting principles in the United States of America by a firm of certified
public accountants of recognized standing); (B) if not included in substance in
its annual report to stockholders, its annual report on Form 10-K (or similar
form); (C) each of its quarterly reports to its stockholders, and, if not
included in substance in its quarterly reports to stockholders, its quarterly
report on Form 10-Q (or similar form); and (D) a copy of the full Registration
Statement (the foregoing, in each case, excluding exhibits); and (ii) upon
request, all exhibits excluded by the parenthetical to the immediately preceding
clause (D), and all other communications from the Company to its stockholders
generally;

                  (g) prior to any sale of Registrable Securities by a Holder
pursuant to the Registration Statement, register or qualify or obtain an
exemption for offer and sale under the securities or blue sky laws of such
jurisdictions as any such Holders reasonably request in writing, and do any and
all other acts or things reasonably necessary or advisable to enable the offer
and sale in such jurisdictions of the Registrable Securities covered by such
Registration Statement, provided that the Company shall not for any such purpose
be required to (i) qualify generally to transact business as a foreign
corporation in any jurisdiction where it is not so qualified, (ii) subject
itself to taxation in any such jurisdiction, or (iii) consent to general service
of process in any such jurisdiction;

                  (h) upon the occurrence of any event contemplated by Section
5.4(b)(v) above, the Company shall promptly prepare a post-effective amendment
to the Registration Statement or a supplement to the related prospectus, so
that, as thereafter delivered to purchasers of the Registrable Securities
included therein, the prospectus will not include any untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading; and

                  (i) use its best efforts to comply with all applicable rules
and regulations of the Commission.

         5.5      (a) Each Holder agrees that, upon receipt of any notice from
the Company of the happening of any event requiring the preparation of a
supplement or amendment to a prospectus relating to Registrable Securities so
that, as thereafter delivered to the Holders with such supplement or amendment,
such prospectus shall not contain an untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein not misleading, each Holder will forthwith discontinue
the offer or disposition of Registrable Securities pursuant to the registration
statement contemplated by Section 5.2 until its receipt of copies of the
supplemented or amended prospectus from the Company (which the Company covenants
to deliver promptly to the Holder), or until advised in writing by the Company
that the current prospectus may be used, and, if so directed by the Company,
each Holder shall deliver to the Company all copies, other than permanent file
copies then in such Holder's possession, of the prospectus covering such
Registrable Securities current

                                      -15-

<PAGE>
at the time of receipt of such notice. Subject to Section 5.5(b) below, the
Company shall prepare and deliver to each Holder as promptly as reasonably
practicable, but no later than thirty (30) days after delivery of such notice by
the Company, an amended or supplemented prospectus, which, as so amended or
supplemented, shall no longer contain any untrue statement of a material fact or
omits to state any material fact required to be stated therein or necessary to
make the statements therein not misleading.

                  (b) Each Holder shall suspend, upon request of the Company,
any disposition of Registrable Securities pursuant to the Registration Statement
and prospectus contemplated by Section 5.2, for a period not to exceed 30 days
and for no more than two such 30 day periods (which may be consecutive) in the
aggregate within any one 12-month period, in the event the Company determines in
good faith that offers and sales pursuant thereto should not be made by reason
of the presence of material undisclosed circumstances or developments with
respect to which the disclosure that would be required in such a prospectus is
premature, would have an adverse effect on the Company, might interfere with any
significant primary underwritten offering of equity securities being
contemplated by the Company, or is otherwise inadvisable.

                  (c) As a condition to the inclusion of its Registrable
Securities, each Holder shall furnish to the Company a completed copy of the
Registration Statement Questionnaire included herein as APPENDIX II hereto and
such other information regarding such Holder and the distribution proposed by
such Holder as the Company may reasonably request in writing and which shall be
required in connection with any registration, qualification or compliance
referred to in this Article 5.

                  (d) Each Holder hereby covenants with the Company not to make
any sale of the Registrable Securities unless they are registered under the Act
(and the Holder complies with the prospectus delivery requirements of the Act)
or unless an exemption from such registration is available with regard to such
sale, and the Holder supplies an opinion of counsel in form and substance
reasonably satisfactory to the Company (other than in cases where the exemption
is clearly available, such as under Rule 144 of the Act).

                  (e) Each Holder acknowledges and agrees that the Registrable
Securities sold pursuant to the Registration Statement described in this Section
are not transferable on the books of the Company unless the stock certificate
submitted to the transfer agent evidencing such Registrable Securities is
accompanied by a certificate, in the form attached hereto as APPENDIX III, to
the effect that (i) the Registrable Securities have been sold in accordance with
such Registration Statement or pursuant to Rule 144 of the Act, and (ii) such
sale complies with the requirement of delivering a current prospectus pursuant
to the Act.

                  (f) Each Holder agrees not to take any action with respect to
any distribution deemed to be made pursuant to such registration statement which
would constitute a violation of Regulation M under the Act and the Exchange Act
or any other applicable rule, regulation or law.

                  (g) At the end of the Registration Period, the Holders of
Registrable Securities included in the Registration Statement shall discontinue
sales of shares pursuant to such Registration Statement upon receipt of notice
from the Company of its intention to remove from

                                      -16-
<PAGE>
registration the shares covered by such Registration Statement which remain
unsold, and such Holders shall notify the Company of the number of shares
registered which remain unsold promptly upon receipt of such notice from the
Company.

         5.6      With a view to making available to the Holders the benefits of
certain rules and regulations of the Commission which at any time permit the
sale of the Registrable Securities to the public without registration, the
Company shall use its best efforts to: (a) make and keep available adequate
public information available, as required under paragraph (c) of Rule 144 under
the Act, at all times;

                  (b) file with the Commission in a timely manner all reports
and other documents required of the Company under Section 13, 14 and 15(d) of
the Exchange Act; and

                  (c) so long as a Holder owns any unregistered Registrable
Securities, furnish to such Holder, upon any reasonable request, a written
statement by the Company as to its compliance with the current public
information requirements of paragraph (c) of Rule 144 under the Act, and of the
Exchange Act, a copy of the most recent annual or quarterly report of the
Company, and such other reports and documents of the Company as such Holder may
reasonably request in availing itself of any rule or regulation of the
Commission allowing a Holder to sell any such securities without registration.

         5.7      In the event that the Registration Statement is not declared
effective within 90 days after the date of filing of the Registration Statement,
the Company shall pay to each Subscriber liquidated damages in an amount equal
to 0.25% of the number of shares of Common Stock purchased by such Subscriber
pursuant to this Agreement for each week after such date that the Registration
Statement is not declared effective. Such liquidated damages shall be the
Subscriber's sole and exclusive remedy in the event that the Registration
Statement is not declared effective within 90 days after the filing date of the
Registration Statement and shall be paid through the issuance of additional
Common Stock at such time as the Registration Statement is declared effective. A
Registration Statement with respect to such additional Common Stock shall also
be filed within 30 days of issuance under the terms and conditions set forth in
this Article 5.

         5.8      The rights to cause the Company to register Registrable
Securities granted to the Holders by the Company under Section 5.2 may be
assigned in full by a Holder in connection with a transfer by such Holder of its
Registrable Securities, provided, however, that (i) such transfer may otherwise
be effected in accordance with applicable securities laws; (ii) such Holder
gives written notice thereof to the Company within a reasonable time after such
assignment; (iii) such transferee agrees to comply with the terms and provisions
of this Agreement; and (iv) such transfer is otherwise in compliance with this
Agreement. Except as specifically permitted hereby, the rights of a Holder with
respect to Registrable Securities as set out herein shall not be transferable to
any other Person, and any attempted transfer shall be void.

6.       INDEMNIFICATION.

         6.1      BY THE COMPANY.

                                      -17-
<PAGE>

                  (a) To the extent permitted by law, the Company shall
indemnify each Holder of the Registrable Securities and each person controlling
such Holder within the meaning of Section 15 of the Act against all claims,
losses, damages and liabilities (or action in respect thereof), including any of
the foregoing incurred in settlement of any litigation, commenced or threatened
(subject to Section 6.3), arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any registration
statement or prospectus, or any amendment or supplement thereof, in connection
with the sale of Common Stock by such Holder, or based on any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and will reimburse
each Holder and each person controlling such Holder for reasonable legal and
other expenses reasonably incurred in connection with investigating or defending
any such claim, loss, damage, liability or action as incurred; PROVIDED that the
Company will not be liable in any such case to the extent that the claim, loss,
damage or liability arises out of or is based upon (i) any untrue statement or
omission or allegation thereof made in reliance upon and in conformity with
written information furnished to the Company by or on behalf of such Holder
specifically for use in preparation of such registration statement, prospectus
or offering circular, and (ii) the failure of the Holder to comply with the
covenants and agreements contained in this Agreement respecting sales of
Registrable Securities; PROVIDED FURTHER that the foregoing indemnity agreement
of the Company is subject to the condition that, insofar as it relates to any
such untrue statement or alleged untrue statement or omission or alleged
omission made in a preliminary prospectus but eliminated or remedied in (i) the
amended prospectus on file with the Commission at the time the registration
statement is ordered effective, or (ii) in the amended prospectus filed with the
Commission pursuant to Rule 424(b) (each a "FINAL PROSPECTUS"), such indemnity
agreement shall not inure to the benefit of any such Holder or any such
controlling person, if a copy of the Final Prospectus was furnished by the
Company to the Holder for delivery, but not furnished by the Holder to the
person or entity asserting the loss, liability, claim or damage at or prior to
the time such furnishing is required by the Act and the Final Prospectus would
have cured the defect giving rise to such loss, liability, claim or damage.

                  (b) The Company agrees to hold the Subscriber and its
directors, officers, employees, controlling persons and agents and their
respective heirs, representatives, successors and assigns harmless and to
indemnify them against all claims, losses, damages, liabilities, actions, costs
and expenses incurred by them that relate to any inaccuracy in the
representations and warranties of the Company contained in this Agreement, or
any failure of the Company to perform its obligations under this Agreement or
under law in connection herewith.

         6.2      BY THE SUBSCRIBER/HOLDERS.

                  (a) Each Holder will severally and not jointly indemnify the
Company, each of its directors and officers and each person who controls the
Company within the meaning of Section 15 of the Act, against all claims, losses,
damages and liabilities (or actions in respect thereof), including any of the
foregoing incurred in settlement of any litigation, commenced or threatened
(subject to Section 6.3), arising out of or based on any untrue statement (or
alleged untrue statement) of a material fact contained in any registration
statement or prospectus, or any amendment or supplement thereof in connection
with the sale of Common Stock by such Holder or based on any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and will reimburse
the

                                      -18-

<PAGE>
Company, such directors and officers and each person controlling the Company for
reasonable legal and any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability or action as
incurred, in each case to the extent, but only to the extent, that such untrue
statement or omission or allegation thereof is made in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
the Holder specifically for use in preparation of such registration statement,
prospectus or offering circular; PROVIDED that the indemnity shall not apply to
the extent that such claim, loss, damage or liability results from (i) the fact
that a current copy of the prospectus was not made available to the Holder and
such current copy of the prospectus would have cured the defect giving rise to
such loss, claim, damage or liability, or (ii) the Holder has delivered to the
Company in writing a correction to such untrue statement or alleged untrue
statement or omission or alleged omission before the occurrence of the event
from which such loss was incurred. Notwithstanding the foregoing, in no event
shall a Holder be liable for any such claims, losses, damages, liabilities or
expenses in excess of the proceeds received by such Holder from sales incident
to such registration or qualification, except in the event of fraud by such
Holder.

                  (b) The Subscriber agrees to hold the Company and its
directors, officers, employees, controlling persons and agents and their
respective heirs, representatives, successors and assigns harmless and to
indemnify them against all liabilities, costs and expenses incurred by them as a
result of any misrepresentation made by the Subscriber contained in this
Agreement (including the Investor Questionnaire contained in Article 8 herein).

         6.3      INDEMNIFICATION PROCEDURE. Each party entitled to
indemnification under this Article 6 (the "INDEMNIFIED PARTY") shall give notice
to the party required to provide indemnification (the "INDEMNIFYING PARTY")
promptly after such Indemnified Party has actual knowledge of any claim as to
which indemnity may be sought, and shall permit the Indemnifying Party to assume
the defense of any such claim or any litigation resulting therefrom, provided
that counsel for the Indemnifying Party, who shall conduct the defense of such
claim or litigation, shall be approved by the Indemnified Party (whose approval
shall not unreasonably be withheld, delayed or conditioned), and the Indemnified
Party may participate in such defense at such Indemnified Party's expense, and
provided further that the failure of any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations
under this Agreement, unless such failure is materially prejudicial to the
Indemnifying Party in defending such claim or litigation. An Indemnifying Party
shall not be liable for any settlement of an action or claim effected without
its written consent (which consent will not be unreasonably withheld, delayed or
conditioned).

         6.4      CONTRIBUTION. If the indemnification provided for in this
Article 6 is held by a court of competent jurisdiction to be applicable by its
terms but is unavailable to an Indemnified Party with respect to any loss,
liability, claim, damage or expense referred to therein, then the Indemnifying
Party, in lieu of indemnifying such Indemnified Party thereunder, shall
contribute to the amount paid or payable by such Indemnified Party as a result
of such loss, liability, claim, damage or expense, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Indemnifying Party
on the one hand and by the Indemnified Party on the other hand from the
placement of the Common Stock, or (ii) if the allocation provided by clause (i)
is not permitted by applicable law, in such proportion as is appropriate to
reflect not only the

                                      -19-

<PAGE>
relative benefits referred to in clause (i), but also the relative fault of the
Indemnifying Party on the one hand and of the Indemnified Party on the other in
connection with the statements or omissions which resulted in such loss,
liability, claim, damage or expense, as well as any other relevant equitable
considerations. The respective relative benefits received by the indemnifying
Party and the Indemnified Party shall be deemed to be in the same proportion as
the amount paid by the Subscriber to the Company pursuant to this Agreement for
the Common Stock purchased by such Subscriber that was sold pursuant to the
Registration Statement bears to the difference (the "DIFFERENCE") between the
amount such Subscriber paid for such Common Stock that was sold pursuant to the
Registration Statement and the amount received from such sale. The relative
fault of the Indemnifying Party and of the Indemnified Party shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Indemnifying Party or by
the Indemnified Party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
Notwithstanding the provisions of this Section 6.4, no Holder shall be required
to contribute any amount in excess of the amount by which the Difference exceeds
the amount of any damages that such Holder has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning

7.       MISCELLANEOUS.

         7.1      Notwithstanding any investigation made by any party to this

this Agreement, the delivery of the Subscriber of the Common Stock being
purchased and the payment therefor.

         7.2      Any notice or other communication given hereunder shall be
deemed sufficient if in writing and sent by registered or certified mail, return
receipt requested, or delivered by hand against written receipt therefore,
addressed to Genta Incorporated, Two Connell Drive, Berkeley Heights, New Jersey

         7.4      Subject to the provisions of Section 5.7 and 7.12, this
Agreement shall be binding upon and inure to the benefit of the parties hereto
and to their respective heirs, legal representatives, successors and assigns.
This Agreement sets forth the entire agreement and understanding between the
parties as to the subject matter hereof and merges and supersedes all prior
discussions, agreements and understandings of any and every nature among them.

         7.5      NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED
BY ANY OF THE PARTIES HERETO, THE PARTIES EXPRESSLY AGREE THAT ALL THE TERMS AND
PROVISIONS HEREOF SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS
OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. IN
THE EVENT THAT A JUDICIAL PROCEEDING IS NECESSARY, THE EXCLUSIVE FORUMS FOR
RESOLVING DISPUTES ARISING OUT OF OR RELATING TO THIS AGREEMENT ARE EITHER THE
STATE OR FEDERAL COURTS LOCATED IN THE STATE OF NEW YORK, AND ALL RELATED
APPELLATE COURTS, THE PARTIES HEREBY IRREVOCABLY CONSENT TO THE JURISDICTION OF
SUCH COURTS AND AGREE TO SAID VENUE.

         7.6      In order to discourage frivolous claims, the parties agree
that unless a claimant in any proceeding arising out of this Agreement succeeds
in establishing his claim and recovering a judgment against another party as
determined in a court of competent jurisdiction in a final, non-appealable order
(regardless of whether such claimant succeeds against one of the other parties
to the action), then the other party shall be entitled to recover from such
claimant all of its reasonable legal costs and expenses relating to such
proceeding and/or incurred in preparation therefore.

         7.7      The holding of any provision of this Agreement to be invalid
or unenforceable by a court of competent jurisdiction shall not affect any other
provision of this Agreement, which shall remain in full force and effect. If any
provision of this Agreement shall be declared by a court of competent
jurisdiction to be invalid, illegal or incapable of being enforced in whole or
in part, such provision shall be interpreted so as to remain enforceable to the
maximum extent permissible consistent with applicable law and the remaining
conditions and provisions or portions thereof shall nevertheless remain in full
force and effect and enforceable to the extent they are valid, legal and
enforceable, and no provisions shall be deemed dependent upon any other covenant
or provision unless so expressed herein.

         7.8      It is agreed that a 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 by that same party.

         7.9      The parties agree to execute and deliver all such further
documents, agreements and instruments and take such other and further action as
may be necessary or appropriate to carry out the purposes and intent of this
Agreement.

         7.10     This Agreement may be executed in two or more counterparts
each of which shall be deemed an original, but all of which shall together
constitute one and the same instrument.

                                      -21-

8.       INVESTOR QUESTIONNAIRE.

         8.1      The Subscriber represents and warrants that he, she or it is
an accredited investor within the meaning of Rule 501(a) under the Act, because
the Subscriber satisfies the criteria set forth in one or more categories marked
below, and that for any category marked, he, she or it has truthfully set forth,
where applicable, the factual basis or reason the Subscriber comes within that
category. The undersigned agrees to furnish any additional information which the
Company deems necessary in order to verify the answers set forth below.

Category A _____           The undersigned is an individual (not a partnership,
                           corporation or other entity.) whose individual net
                           worth, or joint net worth with his or her spouse,
                           presently exceeds $1,000,000.

                           EXPLANATION. In calculating net worth you may include

                           investments, stock and securities. Equity in personal
                           property and real estate should be based on the fair
                           market value of such property less debt secured by
                           such property.

                           corporation or other entity) who had an income in

                           years, or joint income with his or her spouse in
                           excess of $300,000 in each of those years (in each
                           case including foreign income, tax exempt income and
                           full amount of capital gains and losses but excluding
                           any income of other family members and any unrealized
                           capital appreciation) and has a reasonable
                           expectation of reaching the same income level in the
                           current year.

                           within the meaning of Title 1 of ERISA and (a) the
                           investment decision is made by a plan fiduciary which
                           is either a bank, savings and loan association,
                           insurance company or registered investment advisor,
                           or (b) the plan has total assets in excess of
                           $5,000,000 or (c) is a self directed plan with

                           of the Internal Revenue Code, in each case not formed
                           for the specific purpose of acquiring the Common
                           Stock and with total assets in excess of $5,000,000
                           (describe entity).

                           -----------------------------------------------------
                           -----------------------------------------------------

Category G _____           The undersigned is a trust with total assets in
                           excess of $5,000,000, not formed for the specific
                           purpose of acquiring the Common Stock, where the
                           purchase is directed by a "sophisticated investor" as
                           defined in Regulation 506(b)(2)(ii) under the Act.

Category H _____           The undersigned is an entity (other than a trust) in

                           investors" within one or more of the above
                           categories. If relying upon this Category alone, each
                           equity owner must complete a separate copy of this

Category I _____           The undersigned is not within any of the categories
                           above and is therefore not an accredited investor.

warranties in this Agreement shall cease to be true, accurate and complete.
