the Company (the "Collateral") in order to secure prompt payment of the
principal sum and interest evidenced by the Notes, and the performance by the
Company of each of its obligations under this Agreement and the Notes. Such
security interest shall automatically terminate upon the earlier of (i) the
payment of principal and interest on the Notes and (ii) such time as the Notes
are no longer outstanding (the "Security Interest Termination Date").

         3.2. Designation of Secured Party as Agent. Purchasers, by their
acceptance of the benefits of this Agreement and the Securities, hereby
irrevocably designate the Secured Party to act as Secured Party on their behalf.
Each Purchaser hereby irrevocably authorizes, and each holder of any Securities,
by such holder's acceptance of such Securities, shall be deemed irrevocably to
authorize, the Secured Party to take such action on their behalf under the
provisions of this Agreement and any other instruments and agreements referred
to herein or therein and to exercise such powers and to perform such duties
hereunder and thereunder as are



                                      -2-


specifically delegated to, or required of, the Secured Party by the terms hereof
or thereof and such other powers as are reasonably incidental thereto. Each
Purchaser, on behalf of itself and future holders of the Securities issued to
such Purchaser, hereby authorizes and directs the Secured Party, from time to
time in the Secured Party's discretion, to take any action and promptly to
execute and deliver on such Purchaser's behalf any document or instrument that
the Company may reasonably request to effect, confirm or evidence the provisions
of this Article 3, the occurrence of the Security Interest Termination Date, any
subordination agreement, or otherwise. Pursuant to Section 9-509(d) of the
Uniform Commercial Code as in effect on the date hereof in the State of New
York, the Secured Party hereby authorizes the Company to file a termination
statement upon the occurrence of the Security Interest Termination Date; the
Secured Party agrees to provide any further authorizations of such filing if
requested by the Company.

         3.3. Delivery of Additional Documentation Required. The Company shall
from time to time execute and deliver to Secured Party, at the request of
Secured Party and within 30 days of such request, all financing statements and
other documents that Secured Party may reasonably request to perfect and
continue perfected Secured Party's security interests in the Collateral, it
being understood and agreed by the Purchasers and the Secured Party that the
Company need not deliver possession or control of any Collateral to the Secured
Party or take any action to perfect the security interest granted hereby other
than the filing of financing statements under the Uniform Commercial Code.

         4. Representations and Warranties of Purchasers. Purchasers hereby
severally represent and warrant to the Company as follows:

         4.1. Investment Intent. Each Purchaser recognizes that the purchase of
the Securities involves a high degree of risk including, but not limited to, the
following: (i) the Company remains a development stage business with limited
operating history and requires substantial funds in addition to the proceeds of
the Offering; (ii) an investment in the Company is highly speculative, and only
investors who can afford the loss of their entire investment should consider
investing in the Company, the Notes, the Warrants, or the shares of
Securities-Underlying Common Stock, (iii) such Purchaser may not be able to
liquidate his investment; (iv) transferability of the Notes, the Warrants and
the Securities-Underlying Common Stock is extremely limited; (v) in the event of
a disposition of the Notes, the Warrants and the Securities-Underlying Common
Stock, such Purchaser could sustain the loss of its entire investment and (vi)
the Company has not paid any dividends since inception and does not anticipate
the payment of dividends on the Common Stock in the foreseeable future.

         4.2. Lack of Liquidity. Each Purchaser confirms that it is able (i) to
bear the economic risk of this investment, (ii) to hold the Notes, the Warrants
and any shares of Securities-Underlying Common Stock for an indefinite period of
time, and (iii) presently to afford a complete loss of its investment; and
represents that it has sufficient liquid assets so that the illiquidity
associated with this investment will not cause any undue financial difficulties
or affect such Purchaser's ability to provide for his or its current needs and
possible financial contingencies, and that his or its commitment to all
speculative investments is reasonable in relation to his or its net worth and
annual income.

                                      -3-


         4.3. Knowledge and Experience. Each Purchaser hereby acknowledges and
represents that such Purchaser has prior investment experience, including
investment in securities that are non-listed, unregistered and are not traded on
the Nasdaq National or SmallCap Market, nor on the National Association of
Securities Dealers, Inc.'s (the "NASD") automated quotation system.

         4.4. Purchaser Capacity. Each Purchaser hereby represents that such
Purchaser has the capacity to protect such Purchaser's own interests in
connection with the transaction contemplated hereby.

         4.5. Receipt of Information. Each Purchaser hereby acknowledges that
such Purchaser has carefully reviewed this Agreement and all attachments to it,
and hereby represents that such Purchaser has been furnished by the Company with
all information regarding the Company which such Purchaser has requested or
desired to know, has been afforded the opportunity to ask questions of, and to
receive answers from, duly authorized officers or other representatives of the
Company concerning the terms and conditions of the Offering, the Notes, the
Warrants and the Securities-Underlying Common Stock and the affairs of the
Company and has received any additional information which such Purchaser or its
representative has requested.

         4.6. Reliance on Information. Each Purchaser has relied solely upon the
information provided by the Company in this Agreement in making the decision to
invest in the Securities. To the extent necessary, each Purchaser has retained,
at the sole expense of such Purchaser, and relied upon, appropriate professional
advice regarding the investment, tax and legal merits and consequences of this
Agreement and its purchase of the Securities, and the conversion of the Notes
into, or exercise of the Warrants for, Securities-Underlying Common Stock.

         4.7. No Solicitation. Each Purchaser represents that (i) such Purchaser
was contacted regarding the sale of the Securities by the Company (or an
authorized agent or representative thereof) with whom such Purchaser had a prior
substantial pre-existing relationship and (ii) no Securities were offered or
sold to such Purchaser by means of any form of general solicitation or general
advertising, and in connection therewith no Purchaser (A) received or reviewed
any advertisement, article, notice or other communication published in a
newspaper or magazine or similar media or broadcast over television or radio
whether closed circuit, or generally available; or (B) attended any seminar

general solicitation or general advertising.

         4.8. Registration. Each Purchaser hereby acknowledges that the Offering

available.

         4.9. Purchase for own Account. Each Purchaser understands that neither

depends, in part, upon such Purchaser's investment intention. In this
connection, each Purchaser hereby represents that such Purchaser is purchasing
Securities for such Purchaser's own account for investment and not with a view
toward the resale or distribution to others or for resale in connection with,
any distribution or public offering (within the meaning of the Securities Act),
nor with any present intention of distributing or selling the same and such
Purchaser has no present or contemplated agreement, undertaking, arrangement,
obligation or commitment providing for the disposition thereof. No Purchaser, if
an entity, was formed for the purpose of purchasing the Securities.

         4.10. Holding Period. Each Purchaser understands that there is no
public market for the Securities or the Securities-Underlying Common Stock and
that no market may ever develop for any such Securities or the
Securities-Underlying Common Stock. Each Purchaser understands and hereby
acknowledges that the Company is under no obligation to register any of the
Securities under the Securities Act or any applicable non-United States, state
securities or "blue sky" laws. Each Purchaser shall hold the Company and its
directors, officers, employees, controlling persons and agents and their
respective heirs, representatives, successors and assigns harmless from, and
shall indemnify them against, all liabilities, costs and expenses incurred by
them as a result of (i) any misrepresentation made by such Purchaser contained
in this Agreement (including in Article 10 hereof), (ii) any sale or
distribution by such Purchaser in violation of the Securities Act or any

         (m) "Selling Expenses" shall mean all underwriting discounts and
selling commissions applicable to the sale of Registrable Securities and all
fees and expenses of legal counsel for any Holder.

         8.2. (a) Demand Registration. On one occasion at any time after six
months after the Registration Date, if Holders of a majority of the Registrable
Securities shall, in writing, state that such Holders desire to sell Registrable
Shares in the public securities markets and request the Company to effect the
registration under the Securities Act of Registrable Securities, the Company
shall promptly use its reasonable best efforts to effect the registration under
the Securities Act of the Registrable Securities which the Company has been so
requested to register; provided, however, that if the managing underwriter
advises the Company that the inclusion of all the securities requested to be
included in such registration would interfere with the successful marketing
(including pricing) of the Registrable Securities proposed to be registered by
the Company, then the number of Primary Shares, Registrable Securities and Other
Shares proposed to be included in such registration shall be included in the
following order:

                  (i) First, the Registrable Securities requested by the Holders
                  to be included in such registration (or, if necessary, such
                  Registrable Securities pro rata among the holders thereof
                  based upon the number of Registrable Securities requested to
                  be registered by each such holders); and

                  (ii)  second, the Other Shares held by the parties
                  requesting inclusion in such registration; and

                  (ii)  third, the Primary Shares.

            (b)   Piggyback Registration

            If the Company at any time after the Registration Date proposes for
any reason to register Primary Shares or Other Shares under the Securities Act
(other than on Form S-4 or Form S-8 promulgated under the Securities Act or any
successor forms thereto), it shall give written notice to the Holders of its
intention to so register such Primary Shares or Other Shares at least 30 days
before the initial filing of such registration statement and, upon the written
request, delivered to the Company within 20 days after delivery of any such
notice by the Company, of the Holders to include in such registration
Registrable Securities (which request shall specify the number of Registrable
Securities proposed to be included in such registration and shall state that
such Holders desire to sell such Registrable Securities in the public securities
markets), the Company shall use its reasonable best efforts to cause all such
Registrable Securities to be included in such registration on the same terms and
conditions as the securities otherwise being sold in such registration;
provided, however, that if the managing underwriter advises the Company that the
inclusion of all the securities requested to be included in such registration
would interfere with the successful marketing (including pricing) of the Primary
Shares or Other Shares proposed to be registered by the Company, then the number
of Primary Shares, Registrable Securities and Other Shares proposed to be
included in such registration shall be included in the following order:

                  (i)   if the Company has initiated the registration:

                                      -11-



                       (A) first, the Primary Shares; and

                  (B) second, the Registrable Securities requested by the
                  Holders to be included in such registration and the Other
                  Shares held by the parties requesting inclusion in such
                  registration (or, if necessary, such Registrable Securities
                  and Other Shares pro rata among the holders thereof based upon
                  the number of Registrable Securities and Other Shares
                  requested to be registered by each such holder).

                  (ii)  if the holders of Other Shares have initiated the
                  registration by exercising a registration demand right;

                  (A)   first, the Other Shares held by such initiating
                  holders ("Other Demand Holders");

                  (B) second, the Other Shares held by persons entitled to
                  registration rights as set forth in the Existing Registration
                  Rights Agreement (the "Existing Holders");

                  (C) third, the Registrable Securities requested by the Holders
                  to be included in such registration and any Other Shares held
                  by parties requesting inclusion in such registration other
                  than the Other Demand Holders and the Existing Holders ("Other
                  Piggy-Back Holders") (or, if necessary, such Registrable
                  Securities and Other Shares held by other Piggy-Back Holders
                  pro rata among the holders thereof based upon the number of
                  Registrable Securities and Other Shares requested to be
                  registered by each such holder); and

                  (D) fourth, the Primary Shares.

         Notwithstanding the foregoing Subsections 8.2(a) and 8.2(b), the
Company shall not be obligated to enter into an underwriting agreement for the
sale of the Registrable Securities.

         8.3. All Registration Expenses incurred in connection with any
registration, qualification or compliance pursuant to Section 8.2 shall be borne
by the Company. All Selling Expenses relating to the sale of securities
registered by or on behalf of Holders shall be borne by such Holders pro rata on
the basis of the number of securities so registered; provided that if a Holder
uses its own legal counsel in addition to one counsel for all of the Holders of
securities registered on behalf of the Holders, such Holder shall bear the cost
of such counsel.

         8.4. In the case of the registration, qualification or compliance
effected by the Company pursuant to this Agreement, the Company shall, upon
reasonable request, inform each Holder as to the status of such registration,
qualification and compliance. At its expense the Company shall:

         (a) use its reasonable best efforts to keep such registration, and any
qualification, exemption or compliance under state securities laws which the
Company



                                      -12-


determines to obtain, continuously effective until the earlier of (i) such time
as the Holders have completed the distribution described in the Registration
Statement relating thereto and (ii) 90 days from the date of initial
effectiveness of such registration. The period of time during which the Company
is required hereunder to keep the Registration Statement effective is referred
to herein as the "Registration Period." Notwithstanding the foregoing, at the
Company's election, the Company may cease to keep such registration,
qualification or compliance effective with respect to any Registrable
Securities, and the registration rights of a Holder shall expire, at such time
as the Holder may sell under Rule 144 under the Securities Act (or other
exemption from registration acceptable to the Company) in a three-month period
all Registrable Securities then desired to be sold by such Holder; and

         (b) advise the Holders:

         (i) when the Registration Statement or any amendment thereto has been
filed with the Securities and Exchange Commission and when the Registration
Statement or any post-effective amendment thereto has become effective;

         (ii) of any request by the Securities and Exchange Commission for
amendments or supplements to the Registration Statement or the prospectus
included therein or for additional information;

         (iii) of the issuance by the Securities and Exchange Commission of any
stop order suspending the effectiveness of the Registration Statement or the
initiation of any proceedings for such purpose;

         (iv) of the receipt by the Company of any notification with respect to
the suspension of the qualification of the Registrable Securities included
therein for sale in any jurisdiction or the initiation or threatening of any
proceeding for such purpose; and

         (v) of the happening of any event that requires the making of any
changes in the Registration Statement or the prospectus included therein so
that, as of such date, the statements therein are not misleading and do not omit
to state a material fact required to be stated therein or necessary to make the
statements therein (in the case of the prospectus, in the light of the
circumstances under which they were made) not misleading;

         (vi) make every reasonable effort to obtain the withdrawal of any order
suspending the effectiveness of any Registration Statement;

         (vii) furnish to each Holder, without charge, at least one copy of such
Registration Statement and any post-effective amendment thereto, including
financial statements and schedules, and, if the Holder so requests in writing,
all exhibits (including those incorporated by reference) in the form filed with
the Securities and Exchange Commission;

         (viii) during the Registration Period, deliver to each Holder, without
charge, as many copies of the prospectus included in such Registration Statement
and any amendment or supplement thereto as such Holder may reasonably request;
and the Company consents to the use, consistent with the provisions hereof, of
the prospectus or any amendment or supplement thereto by each of the selling
Holders of Registrable Securities in connection with the offering



                                      -13-


and sale of the Registrable Securities covered by the prospectus and any
amendment or supplement thereto;

         (ix) subject to the execution of confidentiality agreements in form and
substance satisfactory to the Company, make available upon reasonable notice and
during normal business hours, for inspection by the holders of Registrable
Securities, any underwriter participating in any disposition pursuant to
Registration Statement and any attorney, accountant or other agent retained by
the Holders or underwriter (collectively, the "Inspectors"), all pertinent
financial and other records, pertinent corporate documents and properties of the
Company (collectively, the "Records"), as shall be reasonably necessary to
enable them to exercise their due diligence responsibility, and cause the
Company's officers, directors and employees to supply all information (together
with the Records, the "Information") reasonably requested by any such Inspector
in connection with a Registration Statement. Any of the Information which the
Company determines in good faith to be confidential, and of which determination
the Inspectors are so notified, shall not be disclosed by the Inspectors unless
(i) the disclosure of such Information is necessary to avoid or correct a
misstatement or omission in a Registration Statement, (ii) the release of such
Information is ordered pursuant to a subpoena or other order from a court of
competent jurisdiction or (iii) such Information has been made generally
available to the public; the Investors agree that they will, upon learning that
disclosure of such Information is sought in a court of competent jurisdiction,
give notice to the Company and allow the Company, at the Company's expense, to
undertake appropriate action to prevent disclosure of the Information deemed
confidential;

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

         (xi) upon the occurrence of any event contemplated by Section 8.4(b)(v)
above, the Company shall promptly prepare a post-effective amendment to the
Registration Statement or a supplement to the related prospectus, or file any
other required document 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

         (xii) use its reasonable best efforts to comply with all applicable
rules and regulations of the Securities and Exchange Commission, and will make
generally available to the Holders not later than 45 days (or 90 days if the
fiscal quarter is the fourth fiscal quarter) after the end of its fiscal quarter
in which the first anniversary date of the effective date of the Registration
Statement occurs, an earnings statement satisfying the provisions of Section
11(a) of the Securities Act.

                                      -14-


         8.5. Material Development Condition. With respect to any Registration
Statement, if the Company determines that, in its good faith judgment, it would
(because of the existence of, or in anticipation of, any acquisition or
corporate reorganization or other transaction, financing activity, stock
repurchase or development involving the Company or any subsidiary, or the
unavailability for reasons substantially beyond the Company's control of any
required financial statements, or because 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 or is otherwise inadvisable or any other event or
condition of similar significance to the Company or any subsidiary) be
disadvantageous (a "Material Development Condition") to the Company or any
subsidiary or its stockholders for such a Registration Statement to become
effective or to be maintained effective or for sales of Registrable Securities
to continue pursuant to the Registration Statement, the Company shall,
notwithstanding any other provisions of this Agreement, be entitled, upon the
giving of a written notice to such effect to any Holder of Registrable
Securities included or to be included in such Registration Statement, (i) to
cause sales of Registrable Securities by such Holder pursuant to such
Registration Statement to cease, (ii) to cause such Registration Statement to be
withdrawn and the effectiveness of such Registration Statement terminated, or
(iii) in the event no such Registration Statement has yet been filed, to delay
filing any such Registration Statement, until the Company determines that, in
its good faith judgment, such Material Development Condition no longer exists
(notice of which the Company shall promptly deliver to any Holder of Registrable
Securities with respect to which any such Registration Statement has been
filed). In the event the Company elects not to withdraw or terminate the
effectiveness of any such Registration Statement but to cause a Holder or
Holders to refrain from selling Registrable Securities for any period during the
registration period, the Registration Period with respect to such Holders shall
be extended by the number of days during the Registration Period that such
Holders are required to refrain from selling Registrable Securities.


         8.6. The Holders shall have no right to take any action to restrain,
enjoin or otherwise delay any registration pursuant to Section 8.2 hereof as a
result of any controversy that may arise with respect to the interpretation or
implementation of this Agreement.

         8.7. To the extent permitted by law, the Company shall indemnify each
Holder, each underwriter of the Registrable Securities and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
with respect to which any registration, qualification or compliance has been
effected pursuant to this Agreement, 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
Subsection 8.7(c) below), arising out of or based on any untrue statement of a
material fact contained in any registration statement, prospectus or offering
circular, or any amendment or supplement thereof, incident to any such
registration, qualification or compliance, or based on any omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, in light of the circumstances in which they
were made, and shall reimburse each Holder, each underwriter of the Registrable
Securities and each person controlling such Holder, for 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
shall not be liable in any such case to the extent that any untrue statement or
omission is made in reliance



                                      -15-


upon and in conformity with information furnished to the Company by or on behalf
of such Holder and stated to be specifically for use in preparation of such
registration statement, prospectus or offering circular; provided that the
Company shall not be liable in any such case where the claim, loss, damage or
liability arises out of or is related to the failure of the Holder to comply
with the covenants and agreements contained in this Agreement respecting sales
of Registrable Securities, and except that the foregoing indemnity agreement is
subject to the condition that, insofar as it relates to any such untrue
statement or omission made in the preliminary prospectus but eliminated or
remedied in the amended prospectus on file with the Securities and Exchange
Commission at the time the registration statement becomes effective or in the
amended prospectus filed with the Securities and Exchange Commission pursuant to
Rule 424(b) of the Securities Act or in the prospectus subject to completion and
term sheet under Rule 434 of the Securities Act, which together meet the
requirements of Section 10(a) of the Securities Act (the "Final Prospectus"),
such indemnity agreement shall not inure to the benefit of any such Holder, any
such underwriter or any such controlling person, if a copy of the Final
Prospectus furnished by the Company to the Holder for delivery was not furnished
to the person or entity asserting the loss, liability, claim or damage at or
prior to the time such furnishing is required by the Securities Act and the
Final Prospectus would have cured the defect giving rise to such loss,
liability, claim or damage.

         (a) Each Holder will severally, if Registrable Securities held by such
Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify the Company, each of
its directors and officers, each underwriter of the Registrable Securities and
each person who controls the Company within the meaning of Section 15 of the
Securities 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 Subsection 8.7(c) below),
arising out of or based on any untrue statement of a material fact contained in
any registration statement, prospectus or offering circular, or any amendment or
supplement thereof, incident to any such registration, qualification or
compliance, or based on any omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
in light of the circumstances in which they were made, and will reimburse the
Company, such directors and officers, each underwriter of the Registrable
Securities 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 is
made in reliance upon and in conformity with written information furnished to
the Company by or on behalf of the Holder and stated to be 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 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. Notwithstanding the foregoing, in no event shall a Holder be liable
for any such claims, losses, damages or liabilities in excess of the proceeds
received by such Holder in the offering, except in the event of fraud by such
Holder.

         (b) Each party entitled to indemnification under this Section 8.7 (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



                                      -16-


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 or delayed), 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.

         8.8. If the indemnification provided for in this Section 8 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, claim, damage, liability or action referred to herein, then
the Indemnifying Party, in lieu of indemnifying such Indemnified Party
hereunder, shall contribute to the amounts paid or payable by such Indemnified
Party as a result of such loss, claim, damage, liability or action in such
proportion as is appropriate to reflect 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, claim, damage,
liability or action as well as any other relevant equitable considerations. The
relative fault of the Indemnifying Party and of the Indemnified Party shall be
determined by reference to, among other things, whether the untrue statement of
a material fact or the 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. No person guilty of fraudulent
misrepresentation shall be entitled to contribution from any person.

         8.9. 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, such prospectus will 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 disposition of Registrable Securities pursuant
to the registration statement contemplated by Section 8.2 until its receipt of
copies of the supplemented or amended prospectus from the Company 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 at the time of receipt
of such notice.

         (a) As a condition to the inclusion of its Registrable Securities, each
Holder shall furnish to the Company such information regarding such Holder and
the distribution proposed by such Holder as the Company may request in writing
or as shall be required in connection with any registration, qualification or
compliance referred to in this Article 8.

         (b) Each Holder hereby covenants with the Company (i) not to make any
sale of the Registrable Securities without effectively causing the prospectus
delivery requirements under the Securities Act to be satisfied, and (ii) if such
Registrable Securities are to be sold by any method or in any transaction other
than on a national securities exchange, the Nasdaq



                                      -17-


National Market, Nasdaq SmallCap Market or in the over-the-counter market, in
privately negotiated transactions, or in a combination of such methods, to
notify the Company at least five (5) business days prior to the date on which
the Holder first offers to sell any such Registrable Securities.

         (c) Each Holder acknowledges and agrees that the Registrable Securities
sold pursuant to the Registration Statement described in this Article 8 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 reasonably satisfactory to the Company to the effect that (i) the
Registrable Securities have been sold in accordance with such Registration
Statement and (ii) the requirement of delivering a current prospectus has been
satisfied.

         (d) Each Holder shall not 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 Securities Exchange Act
of 1934, as amended (the "Exchange Act") or any other applicable rule,
regulation or law.

         (e) At the end of the period during which the Company is obligated to
keep the Registration Statement current and effective as described above, 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 registration
the shares covered by such Registration Statement which remain unsold such
Holders shall notify the Company of the number of shares registered which remain
unsold immediately upon receipt of such notice from the Company.

         8.10. With a view to making available to the Holders the benefits of
certain rules and regulations of the Securities and Exchange Commission which at
any time permit the sale of the Registrable Securities to the public without
registration, the Company shall use its reasonable best efforts following the
initial public offering of securities of the Company pursuant to an effective
Registration Statement:

         (a) to make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act, at all times;

         (b) to file with the Securities and Exchange Commission in a timely
manner all reports and other documents required of the Company under the
Exchange Act; and

         8.11. The rights to cause the Company to register Registrable
Securities granted to the Holders by the Company under Section 8.2 may be
assigned in full by a Holder in connection with a transfer by such Holder of its
Registrable Securities, provided that (i) such transfer may otherwise be
effected in accordance with applicable securities laws; (ii) such transfer
involves not fewer than the fewer than a majority of the Registrable Securities
held by such Holder, (iii) such Holder gives prior written notice to the
Company; and (iv) such transferee agrees to comply with the terms and provisions
of this Agreement, and such transfer is otherwise in compliance with this
Agreement. Except as specifically permitted by this Section 8.10, the rights of
a Holder with respect to Registrable Securities as set out herein shall not be
transferable



                                      -18-


to any other Person, and any attempted transfer shall cause all rights of such
Holder therein to be forfeited.

         8.12. Lock-Up Period. If the Company shall effect a primary or a
secondary public offering of its securities or if at any time, the Company shall
register its shares of Common Stock under the Securities Act for sale to the
public on a registration statement under which the Holders are given the
opportunity to have their Registrable Securities registered (including any such
registration in accordance with this Agreement), the Holders shall not sell
publicly, make any short sale of, grant any option for the purchase of, or
otherwise dispose publicly of, any Registrable Securities (other than those
shares of Common Stock included in such registration in accordance with this
Agreement) without the prior written consent of the Company, during the period
beginning ten (10) days prior to the effectiveness of the registration statement
pursuant to which such public offering shall be made and ending on the date 180
days after the effective date of such registration statement.

         9. Miscellaneous.

         9.1. Amendments and Waivers. This Agreement and all exhibits and
schedules hereto set forth the entire agreement and understanding among 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.
This Agreement may be amended only by mutual written agreement of the Company
and the Purchaser or Purchasers holding a majority of the Securities-Underlying
Common Stock on a fully-diluted basis (the "Purchaser Majority"), and the
Company may take any action herein prohibited or omit to take any action herein
required to be performed by it, and any breach of any covenant, agreement,
warranty or representation may be waived, only if the Company has obtained the
written consent or waiver of the Purchaser Majority.

         (a) After an amendment or waiver becomes effective it shall bind every
holder of Securities regardless of whether such holder held such Securities at
the time such amendment or waiver became effective, or subsequently acquired
such Securities.

         9.2. Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the Company and its successors and assigns and
Purchasers and their successors and registered assigns.

         9.3. Notices. All notices, demands and other communications to be given
or delivered under or by reason of the provisions of this Agreement shall be in
writing and shall be deemed to have been given personally or when mailed by
certified or registered mail, return receipt requested and postage prepaid, or
by a nationally recognized overnight courier service and addressed to the
addresses of the respective parties set forth below or to such changed addresses
as such parties may have fixed by notice; provided, however, that any notice of
change of address shall be effective only upon receipt:

                                  Note due 2003

$1,500,000
                                                      August 5, 2002

            Nephros,  Inc.,  a  Delaware  Company,  (the  "Company"),  for value
received,  hereby promises to pay to Lancer  Offshore,  Inc. (the "Holder"),  or
registered  assigns,  the principal sum set forth above, with accrued but unpaid
interest  thereon  at a rate  equal to eight  percent  (8%)  per  annum,  on the
Maturity Date.  Payment shall be made at such place as designated by the Company
upon  surrender  of this Note (as defined  below),  and shall be in such coin or
currency  of the United  States of  America  as at the time of payment  shall be
legal tender for the payment of public and private debts.  This Note is one of a
duly authorized issue of Nephros, Inc. Notes due 2003 (individually a "Note" and
collectively the "Notes") issued pursuant to the Subscription Agreement. Certain
capitalized  terms used herein are defined in Section 8. Capitalized  terms used
herein without definition have the respective meanings specified therefor in the
Subscription Agreement.  The Notes are secured by the Collateral pursuant to the
Subscription Agreement.



SECTION 1.  Interest.

            The Company will pay interest in arrears on the Maturity Date.
Interest on this Note will accrue from the date of its issuance set forth above.

SECTION 2.  Prepayment.

            Upon 30 days prior written notice to the Holder, this Note
(including interest accrued on the principal hereof) may be prepaid by the
Company, at any time, in whole or in part, without penalty or premium.

SECTION 3.  Conversion

            (a) Conversion. The Holder may elect, at any time prior to the
Maturity Date, to convert this Note and all accrued interest hereon into a
number of shares of Common Stock equal to the principal amount of Note being
converted divided by the then current Conversion Price.

            (b) Conversion Procedures. (i) Any Holder of a Note desiring to
convert such Note into Common Stock shall surrender such Note at the Company's
principal executive office, accompanied by proper instruments of transfer to the
Company or in blank, accompanied by irrevocable written notice to the Company
that the Holder elects so to convert such Note (the "Notice of Conversion") and
specifying the name or names (with address) in which a certificate or
certificates evidencing shares of Common Stock are to be issued; provided,
however, in the event that the Holder or Holders submit a Notice of Conversion
with respect to a principal amount outstanding of Notes equal to all the
then-outstanding principal amount of Notes, the Company shall not be required to
honor such Notice of Conversion unless the Secured Party shall have provided the
Company with any authorizations requested by the Company to file a termination
statement with respect to the Secured Party's security interest in the
Collateral, as set forth in subsection 2.2 of the Subscription Agreement.

                (ii) The Company need not deem a Notice of Conversion to be
received unless the Holder complies with all the provisions hereof. The Company
will make a notation of the date that a Notice of Conversion is received, which
date of receipt shall be deemed to be the date of receipt for purposes hereof.

                (iii) The Company shall, as soon as practicable after such
deposit of any Note accompanied by a Notice of Conversion and compliance with
any other conditions herein contained, deliver to the person for whose account
such Note was so surrendered certificates evidencing the number of full shares
of Common Stock to which such person shall be entitled as aforesaid, subject to
Section 4.

                (iv) Subject to the following provisions of this paragraph
3(b)(iv), such conversion shall be deemed to have been made as of the date of
such surrender of the Note to be converted, and the person or persons entitled
to receive the Common Stock deliverable upon conversion of such Note shall be
treated for all purposes as the record holder or holders of such Common Stock on
such date and the Note shall no longer be deemed outstanding and all rights
whatsoever in respect thereof (including the right to receive interest thereon)
shall terminate except the right to receive the number of full shares of Common
Stock to which such person

                                      -2-


shall be entitled hereunder; provided, however, that the Company shall not be
required to convert any Note while the stock transfer books of the Company are
closed for any purpose, but the surrender of a Note for conversion during any
period while such books are so closed shall become effective for conversion
immediately upon the reopening of such books as if the surrender had been made
on the date of such reopening, and the conversion shall be at the Conversion
Rate in effect on such date applied to the principal amount of Note to be
converted.

            (c) Adjustments to Conversion Price. (i) In case the Company shall
hereafter (A) pay a dividend or make a distribution on its Common Stock in
shares of Common Stock, (B) subdivide its outstanding shares of Common Stock
into a greater number of shares or (C) combine its outstanding shares of Common
Stock into a smaller number of shares (each of (A) through (C) an "Action"), the
Conversion Price shall be adjusted to equal the product of the Conversion Price
in effect immediately prior to such Action multiplied by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such Action and the denominator of which shall be the
number of shares of Common Stock outstanding immediately following such Action.
An adjustment made pursuant to this subsection 3(c) shall become effective
immediately after the record date in the case of a dividend or distribution and
shall become effective immediately after the effective date in the case of a
subdivision, combination or reclassification.

                (ii) In case the Company shall hereafter issue by
reclassification of its Common Stock any shares of capital stock of the Company
(a "Reclassification"), provision shall be made so that, immediately following
such Reclassification, the Notes shall be convertible into the kind and quantity
of securities to which the Holders of such Notes would have been entitled
pursuant to such Reclassification, had such Holders converted such Notes
immediately prior to such Reclassification.

                (iii) In case the Company shall hereafter issue any shares of
Common Stock other than Excluded Stock without consideration or for a
consideration per share less than the Conversion Price in effect immediately
prior to the issuance of such Common Stock, then such Conversion Price, as in
effect immediately prior to each such issuance, shall forthwith be lowered to a
price equal to the quotient obtained by dividing:

                       (A) an amount equal to the sum of (x) the total number of
              shares of Common Stock outstanding on a fully-diluted basis
              immediately prior to such issuance, multiplied by the Conversion
              Price in effect immediately prior to such issuance, and (y) the
              consideration received by the Company upon such issuance; by

                       (B) the total number of shares of Common Stock
              outstanding on a fully-diluted basis immediately after the
              issuance of such Common Stock.

                (iv) For the purposes of any adjustment of a Conversion Price
pursuant to clause 3(c)(iii) above, the following provisions shall be
applicable:

                       (A) In the case of the issuance of Common Stock for cash
              in a public offering or private placement, the consideration shall
              be deemed to be the amount of cash paid therefor after deducting
              therefrom any discounts,

                                      -3-


              commissions or placement fees payable by the Company to any
              underwriter or placement agent in connection with the issuance and
              sale thereof.

                       (B) In the case of the issuance of Common Stock for a
              consideration in whole or in part other than cash, the
              consideration other than cash shall be deemed to be the fair
              market value thereof as determined in good faith by the Board of
              Directors of the Company, irrespective of any accounting
              treatment.

                       (C) In the case of the issuance of options to purchase or
              rights to subscribe for Common Stock, securities by their terms
              convertible into or exchangeable for Common Stock, or options to
              purchase or rights to subscribe for such convertible or
              exchangeable securities except for options to acquire Excluded
              Stock:

                            (1) the aggregate maximum number of shares of Common
                  Stock deliverable upon exercise of such options to purchase or
                  rights to subscribe for Common Stock shall be deemed to have
                  been issued at the time such options or rights were issued and
                  for a consideration equal to the consideration (determined in
                  the manner provided in subdivisions (A) and (B) above), if
                  any, received by the Company upon the issuance of such options
                  or rights plus the minimum purchase price provided in such
                  options or rights for the Common Stock covered thereby;

                            (2) the aggregate maximum number of shares of Common
                  Stock deliverable upon conversion of or in exchange for any
                  such convertible or exchangeable securities or upon the
                  exercise of options to purchase or rights to subscribe for
                  such convertible or exchangeable securities and subsequent
                  conversion or exchange thereof shall be deemed to have been
                  issued at the time such securities, options, or rights were
                  issued and for a consideration equal to the consideration
                  received by the Company for any such securities and related
                  options or rights (excluding any cash received on account of
                  accrued interest or accrued dividends), plus the additional
                  consideration, if any, to be received by the Company upon the
                  conversion or exchange of such securities or the exercise of
                  any related options or rights (the consideration in each case
                  to be determined in the manner provided in subdivisions (A)
                  and (B) above);

                            (3) on any change in the number of shares or
                  exercise price of Common Stock deliverable upon exercise of
                  any such options or rights or conversions of or exchanges for
                  such securities, other than a change resulting from the
                  antidilution provisions thereof, the Conversion Price shall
                  forthwith be readjusted to such Conversion Price as would have
                  been obtained had the adjustment made upon the issuance of
                  such options, rights or securities not converted prior to such
                  change, or options or rights related to such securities not
                  converted prior to such change, been made upon the basis of
                  such change;

                                      -4-


                            (4) on the expiration of any such options or rights,
                  the termination of any such rights to convert or exchange or
                  the expiration of any options or rights related to such
                  convertible or exchangeable securities, the Conversion Price
                  shall forthwith be readjusted to such Conversion Price as
                  would have been obtained had the adjustment made upon the
                  issuance of such options, rights, securities or options or
                  rights related to such securities been made upon the basis of
                  the issuance of only the number of shares of Common Stock
                  actually issued upon the exercise of such options or rights,
                  upon the conversion or exchange of such securities, or upon
                  the exercise of the options or rights related to such
                  securities and subsequent conversion or exchange thereof; and

                            (5) No further adjustment of the Conversion Price
                  adjusted upon the issuance of any such options, rights,
                  convertible securities or exchangeable securities shall be
                  made as a result of the actual issuance of Common Stock on the
                  exercise of any such rights or options or any conversion or
                  exchange of any such securities.


                  (v) No adjustment in any Conversion Price shall be required
unless such adjustment would require an increase or decrease of at least $0.01
in such Conversion Price; provided, that any adjustments not required to be made
by virtue of this sentence shall be carried forward and taken into account in
any subsequent adjustment. All calculations under this paragraph 3(c)(v) shall
be made to the nearest one hundredth (1/100) of a cent or the nearest one tenth
(1/10) of a share, as the case may be.

                  (vi) In any case in which the provisions of this subsection
3(c) shall require that an adjustment shall become effective immediately after a
record date of an event, the Company may defer until the occurrence of such
event (1) issuing to the Holder of any Notes converted after such record date
and before the occurrence of such event the shares of capital stock issuable
upon such conversion by reason of the adjustment required by such event in
addition to the shares of capital stock issuable upon such conversion before
giving effect to such adjustments, and (2) paying to such Holder any amount in
cash in lieu of a fractional share of capital stock pursuant to Section 4 below;
provided, however, that the Company shall deliver to such Holder an appropriate
instrument evidencing such Holder's right to receive such additional shares and
such cash.

                  (vii) Whenever a Conversion Price shall be adjusted as
provided in subsection 3(c), the Company shall make available for inspection
during regular business hours, at its principal executive offices or at such
other place as may be designated by the Company, a statement, signed by its
chief executive officer, showing in reasonable detail the facts requiring such
adjustment and the Conversion Price that shall be in effect after such
adjustment. The Company shall also cause a copy of such statement to be sent by
first class certified mail, return receipt requested and postage prepaid, to
each Holder of Notes at such Holder's address appearing on the Company's
records. Where appropriate, such copy may be given in advance and may be
included as part of any notice required to be mailed under the provisions of
paragraph (viii) below.

                                      -5-


                  (viii) If the Company shall propose to take any action of the
types described in paragraphs 3(c)(i) and 3(c)(ii), the Company shall give
notice to each Holder, in the manner set forth in paragraph (vii) above, which
notice shall specify the record date, if any, with respect to any such action
and the date on which such action is to take place. Such notice shall also set
forth such facts with respect thereto as shall be reasonably necessary to
indicate the effect of such action (to the extent such effect may be known at
the date of such notice) on the Conversion Price and the number, kind or class
of shares or other securities or property which shall be deliverable or
purchasable upon the occurrence of such action or deliverable upon conversion of
such Holder's Note. In the case of any action which would require the fixing of
a record date, such notice shall be given at least 20 days prior to the date so
fixed, and in case of all other action, such notice shall be given at least 30
days prior to the taking of such proposed action. Failure to give such notice,
or any defect therein, shall not affect the legality or validity of any such
action.

             (d) Reservation of Shares; Transfer Taxes; Etc. The Company shall
at all times reserve and keep available, out of its authorized and unissued
shares of Common Stock, solely for the purpose of effecting the conversion of
the Notes, such number of shares of its Common Stock free of preemptive rights
as shall be sufficient to effect the conversion of all Notes from time to time
outstanding. The Company shall use its best efforts from time to time, in
accordance with the laws of the State of Delaware, to increase the authorized
number of shares of Common Stock if at any time the number of shares of Common
Stock not outstanding shall not be sufficient to permit the conversion of all
the then-outstanding Notes.

             The Company shall pay any and all issue or other taxes (other than
income taxes) that may be payable in respect of any issue or delivery of shares
of Common Stock on conversion of the Notes. The Company shall not, however, be
required to pay any tax which may be payable in respect of any transfer involved
in the issue or delivery of Common Stock (or other securities or assets) in a
name other than that in which the Notes so converted were registered, and no
such issue or delivery shall be made unless and until the person requesting such
issue has paid to the Company the amount of such tax or has established, to the
satisfaction of the Company, that such tax has been paid.

             (e) Automatic Conversion. This Note shall automatically convert
into shares of Common Stock at the then-current Conversion Rate upon the
occurrence of a Qualified IPO.

             (f) Other Changes in Conversion Rate. The Company from time to time
may increase the Conversion Rate by any amount for any period of time if the
period is at least 20 days and if the increase is irrevocable during the period.
Whenever the Conversion Rate is so increased, the Company shall mail to the
Holder of record of this Note a notice of the increase at least 15 days before
the date the increased Conversion Rate takes effect, and such notice shall state
the increased Conversion Rate and the period it will be in effect.

             The Company may make such increases in the Conversion Rate, in
addition to those required or allowed by this Section 3, as shall be determined
by it, as evidenced by a resolution of the Board of Directors of the Company, to
be advisable in order to avoid or diminish any income tax to holders of Common
Stock resulting from any dividend or distribution of stock or issuance of rights
or warrants to purchase or subscribe for stock or from any event treated as such
for income tax purposes.

                                      -6-


SECTION 4.  Fractional Shares.

            No fractional shares or scrip representing fractional shares of
Common Stock shall be issued upon conversion of this Note. If more than one
certificate evidencing Notes shall be surrendered for conversion at one time by
the same Holder, the number of full shares issuable upon conversion thereof
shall be computed on the basis of the aggregate principal amount of the Notes so
surrendered. Instead of any fractional share of Common Stock which would
otherwise be issuable upon conversion of this Note (or of such aggregate number
of Notes), the Company may elect, in its sole discretion, independently for each
Holder, whether such number of shares of Common Stock will be rounded to the
nearest whole share (with a .5 of a share rounded upward) or whether such Holder
will be given cash, in lieu of any fractional share, in an amount equal to the
same fraction of the Conversion Price as of the close of business on the day of
conversion.

SECTION 5.  Events of Default Defined.

            The following shall each constitute an "Event of Default" hereunder:

Noteholders"), by notice to the Company, may declare the unpaid principal of and
accrued interest on all the Notes then outstanding to be due and payable (an
"Acceleration"). Upon any such declaration, such principal and accrued interest
shall be due and payable immediately. Majority Noteholders may rescind an
Acceleration and its consequences; provided, however, that no such rescission
shall effect any subsequent Default or impair any right consequent thereto.

            (b) Majority Noteholders may waive an existing Default or Event of
Default and its consequences. Upon any such waiver, such Default shall cease to
exist and any Event of Default arising therefrom shall be deemed to have been
cured for every purpose of this Note; but no such waiver shall extend to any
subsequent or other Default or impair any right consequent thereon.

            (c) In addition to any rights the Holders may have as set forth in
the Subscription Agreement, if the Company defaults in a payment of interest on
the Notes, then, during the continuance of such default, in lieu of this Note's
ordinary 8% interest, the Company shall pay defaulted interest at a rate equal
to the lesser of 18% or the maximum rate allowed by applicable law.

            (d) Upon the occurrence and during the continuance of an Event of
Default, Majority Noteholders may, at their election, without notice of its

exercise of any rights accorded a secured creditor under the Uniform Commercial
Code as in effect in New York.

            (e) To the extent permitted by law, the remedies provided herein
shall be exclusive of any other remedies now or hereafter existing at law or in
equity or by statute or otherwise.

            (f) In any suit for the enforcement of any right or remedy under
this Note or the Subscription Agreement, a court in its discretion may require
the filing by any party litigant in the suit of an undertaking to pay the costs
of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys' fees, against any party litigant in the suit,
having due regard to the merits and good faith of the claims or defenses made by
the party litigant.

reasonably satisfactory to it of the loss, theft, destruction or mutilation of

                                [Form of Warrant]


THE TERMS OF THIS WARRANT ARE SUBJECT TO THE TERMS OF A SUBSCRIPTION AGREEMENT,
COPIES OF WHICH ARE AVAILABLE FROM NEPHROS, INC. NEITHER THIS WARRANT NOR THE
SECURITIES FOR WHICH IT IS EXERCISABLE HAVE BEEN REGISTERED UNDER THE UNITED
STATES SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY
APPLICABLE STATE SECURITIES LAWS, AND MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED

APPLICABLE JURISDICTIONS.

THE SALE, TRANSFER, ASSIGNMENT, PLEDGE, OR ENCUMBRANCE OF THE SECURITIES

                                NEPHROS, INC.


                Class A Warrant for the Purchase of Shares of
                                  Common Stock


No. A-1                                                         August 5, 2002


            FOR VALUE RECEIVED, NEPHROS, INC., a Delaware corporation (the
"Company"), hereby certifies that Lancer Offshore, Inc. or its registered
assigns (the "Holder") is entitled to purchase from the Company, subject to the
provisions of this Warrant (the "Warrant"), at any time on or after the date
hereof (the "Initial Exercise Date"), and prior to 12:01 A.M., New York City
time, on December 1, 2007 (the "Termination Date"), 120,000 fully paid and
non-assessable shares of the Common Stock, $.001 par value, of the Company
("Common Stock"), at an exercise price of $2.50 per share of Common Stock for an
aggregate exercise price of three hundred thousand dollars ($300,000) (the
aggregate purchase price payable for the Warrant Shares hereunder is hereinafter
sometimes referred to as the "Aggregate Exercise Price"). The number of shares
of Common Stock to be received upon exercise of this Warrant and the price to be
paid for each share of Common Stock are subject to possible adjustment from time
to time as hereinafter set forth. The shares of Common Stock or other



securities or property deliverable upon such exercise as adjusted from time to
time is hereinafter sometimes referred to as the "Warrant Shares." The exercise
price of a share of Common Stock in effect at any time and as adjusted from time
to time is hereinafter sometimes referred to as the "Per Share Exercise Price."
The Per Share Exercise Price is subject to adjustment as hereinafter provided;
in the event of any such adjustment, the number of Warrant Shares shall also be
adjusted, by dividing the Aggregate Exercise Price by the Per Share Exercise
Price in effect immediately after such adjustment. The Aggregate Exercise Price
is not subject to adjustment except to the extent of any partial exercise of
this Warrant. This Warrant constitutes one in a series of warrants (the "Class A
Warrants") which includes this Warrant and any other Class A Warrants issued
pursuant to Section 1 and/or Section 2.2 of the Subscription Agreement dated as
of even date herewith (the "Subscription Agreement") by and among the Company
and the Purchasers (as defined in the Subscription Agreement).

            1.    Exercise of Warrant.

            (a) This Warrant may be exercised in whole or in part, at any time
by its holder commencing on the Initial Exercise Date and prior to the
Termination Date by presentation and surrender of this Warrant, together with
the duly executed subscription form attached at the end hereof, at the address
set forth in Subsection 8(a) hereof, together with payment, by certified or
official bank check or wire transfer payable to the order of the Company, of the
Aggregate Exercise Price or the proportionate part thereof if exercised in part.

            (b) If this Warrant is exercised in part only, the Company shall,
upon presentation of this Warrant upon such exercise, execute and deliver (along
with the certificate for the Warrant Shares purchased) a new Warrant evidencing
the rights of the Holder hereof to purchase the balance of the Warrant Shares
purchasable hereunder upon the same terms and conditions as herein set forth.
Upon proper exercise of this Warrant, the Company promptly shall deliver
certificates for the Warrant Shares to the Holder duly legended as authorized by
the subscription form. No fractional shares or scrip representing fractional
shares shall be issued upon exercise of this Warrant; provided that the Company
shall pay to the Holder of the Warrant cash in lieu of such fractional shares.

            2. Reservation of Warrant Shares; Fully Paid Shares; Taxes. The
Company hereby represents that it has, and until expiration of this Warrant
agrees that it shall, reserve for issuance or delivery upon exercise of this
Warrant, such number of shares of the Common Stock as shall be required for
issuance and/or delivery upon exercise of this Warrant in full, and agrees that
all Warrant Shares so issued and/or delivered will be validly issued, fully paid
and non-assessable, and further agrees to pay all taxes (other than income
taxes) and charges that may be imposed upon such issuance and/or delivery. The
Company shall not, however, be required to pay any tax which may be payable in
respect of any transfer involved in the issue or delivery of Common Stock (or
other securities or assets) in a name other than that in which the Warrants so
exercised were registered, and no such issue or delivery shall be made unless
and until the person requesting such issue has paid to the Company the amount of
such tax or has established, to the satisfaction of the Company, that such tax
has been paid.


                                      -2-


            3.    Protection Against Dilution.

            (a) In case the Company shall hereafter (i) pay a dividend or make a
distribution on its capital stock in shares of Common Stock, (ii) subdivide its
outstanding shares of Common Stock into a greater number of shares, (iii)
combine its outstanding shares of Common Stock into a smaller number of shares
or (iv) issue by reclassification of its Common Stock any shares of capital
stock of the Company (each of (i) through (iv) an "Action"), the Per Share
Exercise Price shall be adjusted to be equal to a fraction, the numerator of
which shall be the Aggregate Exercise Price and the denominator of which shall
be the number of shares of Common Stock or other capital stock of the Company
that the Holder would have held (solely as a result of the exercise of this
Warrant and the operation of such Action) immediately following such Action if
this Warrant had been exercised immediately prior to such Action. An adjustment
made pursuant to this Subsection 3(b) shall become effective immediately after
the record date in the case of a dividend or distribution and shall become
effective immediately after the effective date in the case of a subdivision,
combination or reclassification.

            (b) In the event of any capital reorganization or reclassification,
or any consolidation or merger to which the Company is a party other than a
merger or consolidation in which the Company is the continuing corporation, or
in case of any sale or conveyance to another entity of the property of the
Company as an entirety or substantially as an entirety, or in the case of any
statutory exchange of securities with another corporation (including any
exchange effected in connection with a merger of a third corporation into the
Company), the Holder of this Warrant shall have the right thereafter to receive
on the exercise of this Warrant the kind and amount of securities, cash or other
property which the Holder would have owned or have been entitled to receive
immediately after such reorganization, reclassification, consolidation, merger,
statutory exchange, sale or conveyance had this Warrant been exercised
immediately prior to the effective date of such reorganization,
reclassification, consolidation, merger, statutory exchange, sale or conveyance
and in any such case, if necessary, appropriate adjustment shall be made in the
application of the provisions set forth in this Section 3 with respect to the
rights and interests thereafter of the Holder of this Warrant to the end that
the provisions set forth in this Section 3 shall thereafter correspondingly be
made applicable, as nearly as may reasonably be, in relation to any shares of
stock or other securities or property thereafter deliverable on the exercise of
this Warrant. The above provisions of this Subsection 3(b) shall similarly apply
to successive reorganizations, reclassifications, consolidations, mergers,
statutory exchanges, sales or conveyances.

            (c) Whenever the Per Share Exercise Price payable upon exercise of
this Warrant is adjusted pursuant to this Section 3, the number of shares of
Common Stock underlying this Warrant shall simultaneously be adjusted to equal
the number obtained by dividing the Aggregate Exercise Price (as the same shall
be reduced to the extent of any partial exercise of this Warrant) by the
adjusted Per Share Exercise Price.

            (d) If, as a result of an adjustment made pursuant to this Section
3, the Holder shall become entitled to receive, upon exercise of the Warrant,
shares of two or more classes of capital stock or shares of Common Stock and
other capital stock of the Company, the Board of Directors (whose determination
shall be conclusive) shall determine the allocation of the


                                      -3-


adjusted Per Share Exercise Price between or among shares or such classes of
capital stock or shares of Common Stock and other capital stock.

            4. Limited Transferability. This Warrant may not be sold,
transferred, assigned or hypothecated by the Holder except in compliance with
the provisions of the Act and the applicable state securities "blue sky" laws,
and is so transferable only upon the books of the Company which it shall cause
to be maintained for such purpose. The Company may treat the registered Holder
of this Warrant as he or it appears on the Company's books at any time as the
Holder for all purposes.

            5. Loss, etc., of Warrant. Upon receipt of evidence satisfactory to
the Company of the loss, theft, destruction or mutilation of this Warrant, and
of indemnity reasonably satisfactory to the Company (which may include a bond),
if lost, stolen or destroyed, and upon surrender and cancellation of this
Warrant, if mutilated, the Company shall execute and deliver to the Holder a new
Warrant of like date, tenor and denomination.

            6.    Investment Intent.

            (a) The Holder represents, by accepting this Warrant, that it
understands that this Warrant and any securities obtainable upon exercise of
this Warrant have not been registered for sale under Federal or state securities
laws and are being offered and sold to the Holder pursuant to one or more
exemptions from the registration requirements of such securities laws. The
Holder is an "accredited investor" within the meaning of Regulation D under the
Securities Act of 1933, as amended (the "Act"). In the absence of an effective
registration of such securities or an exemption therefrom, any certificates for
such securities shall bear the legend set forth on the first page hereof. The
Holder understands that it must bear the economic risk of its investment in this
Warrant and any securities obtainable upon exercise of this Warrant for an
indefinite period of time, as this Warrant and such securities have not been
registered under Federal or state securities laws and therefore cannot be sold
unless subsequently registered under such laws, unless as exemption from such
registration is available.

            (b) The Holder, by its acceptance of its Warrant, represents to the
Company that it is acquiring this Warrant and will acquire any securities
obtainable upon exercise of this Warrant for its own account for investment and
not with a view to, or for sale in connection with, any distribution thereof in
violation of the Act. The Holder agrees that this Warrant and any such
securities will not be sold or otherwise transferred unless (i) a registration
statement with respect to such transfer is effective under the Act and any
applicable state securities laws or (ii) such sale or transfer is made pursuant
to one or more exemptions from the Act.

            7. Status of Holder. This Warrant does not confer upon the Holder
any right to vote or to consent to or receive notice as a stockholder of the
Company, as such, in respect of any matters whatsoever, or any other rights or
liabilities as a stockholder, prior to the exercise hereof.

            8. Notices. No notice or other communication under this Warrant
shall be effective unless, but any notice or other communication shall be
effective and shall be deemed to have been given if, the same is in writing and
is mailed by first-class mail, postage prepaid, addressed to:


                                      -4-


            (a)   the Company  c/o Audubon  Business  and  Technology  Center,
      Columbia-Presbyterian  Medical  Center,  3960 Broadway,  4th Floor,  New
      York,  NY 10032,  Attention:  President,  or such  other  address as the
      Company has designated in writing to the Holder; or

            (b)   the  Holder  at  Kaya  Flamboyan  9,  Curacao,  Netherlands,
      Antilles,  Attention:  Investment  Manager, or such other address as the
      Holder has designated in writing to the Company.

            9.    Headings.  The headings of this  Warrant have been  inserted
as a matter of convenience and shall not affect the construction hereof.

            10.   Applicable  Law.  This  Warrant  shall  be  governed  by and
construed in accordance  with the law of the State of New York without  giving
effect to principles of conflicts of law thereof.

            11. Amendments. This Warrant may be amended only by mutual written
agreement of the Company and the holder or holders holding Class A Warrants
exercisable for a majority of the shares of Common Stock issuable upon exercise
of all then-outstanding Class A Warrants (the "Majority Holders"), and the
Company may take any action herein prohibited or omit to take any action herein
required to be performed by it, and any breach of any covenant, agreement,
warranty or representation may be waived, only if the Company has obtained the
written consent or waiver of the Majority Holders.
