      (B) All capitalized terms used and not defined herein have the respective

      2. Registration

      (A) Filing and Effectiveness of Registration Statement. The Company shall
prepare and file with the Commission as soon as practicable a Registration
Statement relating to the offer and sale of the Registrable Securities (and up
to 105,000 additional shares of common stock) and shall use its best efforts to
cause the Commission to declare such Registration Statement effective under the
Securities Act as promptly as practicable but in no event later than the
Deadline (as defined in the Debenture). The Company shall promptly (and, in any
event, no more than 24 hours after it receives comments from the Commission),
notify the Buyer when and if it receives any comments from the Commission on the
Registration Statement and promptly forward a copy of such comments, if they are
in writing, to the Buyer. At such time after the filing of the Registration
Statement pursuant to this Section 2(A) as the Commission indicates, either
orally or in writing, that it has no further comments with respect to such
Registration Statement or that it is willing to entertain appropriate requests
for acceleration of effectiveness of such Registration Statement, the Company
shall promptly, and in no event later than two (2) business days after receipt
of such indication from the Commission, request that the effectiveness of such
Registration Statement be accelerated within forty-eight (48) hours of the
Commission's receipt of such request. The Company shall notify the Initial
Investor by written notice that such Registration Statement has been declared
effective by the Commission within 24 hours of such declaration by the
Commission.

      (B) Eligibility for Use of Form S-3. The Company agrees that at such time
as it meets all the requirements for the use of Securities Act Registration
Statement on Form S-3 and it shall file all reports and information required to
be filed by it with the Commission in a timely manner and take all such other
action so as to maintain such eligibility for the use of such form.

      (C) Additional Registration Statement. In the event the Current Market
Price declines to a price per share the result of which is that the Company
cannot satisfy its conversion obligations to Initial Investor hereunder, the
Company shall, to the extent required by the Securities Act (because the
additional shares were not covered by the Registration Statement filed pursuant
to Section 2(a)), as reasonably determined by the Initial Investor, file an
additional Registration Statement with the Commission for such additional number
of Registrable Securities as would be issuable upon conversion of the Debenture
(the "Additional Registrable Securities") in addition to those previously
registered. The Company shall, to the extent required by the Securities Act, as
reasonably determined by the Initial Investor, prepare and file with the
Commission not later than the 30th day thereafter, a Registration Statement
relating to the offer and sale of such Additional Registrable Securities and
shall use its best efforts to cause the Commission to declare such Registration
Statement effective under the Securities Act as promptly as practicable but not
later than the Deadline. The Company shall not include any other securities in
the Registration Statement relating to the offer and sale of such Additional
Registrable Securities.

      (D) (i) If the Company proposes to register any of its warrants, Common
Stock or any other shares of common stock of the Company under the Securities
Act

                                       3

<PAGE>

(other than a registration (A) on Form S-8 or S-4 or any successor or similar
forms, (B) relating to Common Stock or any other shares of common stock of the
Company issuable upon exercise of employee share options or in connection with
any employee benefit or similar plan of the Company or (C) in connection with a
direct or indirect acquisition by the Company of another Person or any
transaction with respect to which Rule 145 (or any successor provision) under
the Securities Act applies), whether or not for sale for its own account, it
will each such time, give prompt written notice at least 20 days prior to the
anticipated filing date of the registration statement relating to such
registration to each Investor, which notice shall set forth such Investor's
rights under this Section 2(D) and shall offer such Investor the opportunity to
include in such registration statement such number of Registrable Securities as
such Investor may request. Upon the written request of any Investor made within
10 days after the receipt of notice from the Company (which request shall
specify the number of Registrable Securities intended to be disposed of by such
Investor), the Company will use its best efforts to effect the registration
under the Securities Act of all Registrable Securities that the Company has been
so requested to register by each Investor, to the extent requisite to permit the
disposition of the Registrable Securities so to be registered; provided,
however, that (A) if such registration involves a Public Offering, each Investor
must sell its Registrable Securities to any underwriters selected by the Company
with the consent of such Investor on the same terms and conditions as apply to
the Company and (B) if, at any time after giving written notice of its intention
to register any Registrable Securities pursuant to this Section 2 and prior to
the effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason not to register such
Registrable Securities, the Company shall give written notice to each Investor
and, thereupon, shall be relieved of its obligation to register any Registrable
Securities in connection with such registration. The Company's obligations under
this Section 2(D) shall terminate on the date that the registration statement to
be filed in accordance with Section 2(A) is declared effective by the
Commission.

            (ii) If a registration pursuant to this Section 2(D) involves a
Public Offering and the managing underwriter thereof advises the Company that,
in its view, the number of shares of Common Stock that the Company and the
Investors intend to include in such registration exceeds the largest number of
shares of Common Stock that can be sold without having an adverse effect on such
Public Offering (the "Maximum Offering Size"), the Company will include in such
registration only such number of shares of Common Stock as does not exceed the
Maximum Offering Size, and the number of shares in the Maximum Offering Size
shall be allocated among the Company, the Investors and any other sellers of
Common Stock in such Public Offering ("Third-Party Sellers"), first, pro rata
among the Investors until all the shares of Common Stock originally proposed to
be offered for sale by the Investors have been allocated, and second, pro rata
among the Company and any Third-Party Sellers, in each case on the basis of the
relative number of shares of Common Stock originally proposed to be offered for
sale under such registration by each of the Investors, the Company and the
Third-Party Sellers, as the case may be. If as a result of the proration
provisions of this Section 2(D)(ii), any Investor is not entitled to include all
such Registrable Securities in such registration, such Investor may elect to
withdraw its request to include any Registrable Securities in such registration.
With respect to registrations pursuant to this Section 2(D), the number of
securities required to satisfy any underwriters' over-allotment option shall be
allocated among the Company, the Investors and any Third Party Seller pro rata
on the basis of the relative number of securities offered for sale under such
registration by each of the Investors, the Company and any such Third Party
Sellers before the exercise of such over-allotment option.

thereof to be current and useable by Investors for resales of the Registrable
Securities for a period of five (5) years from the date on which the

Registrable Securities covered by the Registration Statement have been sold
pursuant thereto in accordance with the plan of distribution provided in the

otherwise transferred in a manner that results in the delivery of new securities
not subject to transfer restrictions under the Securities Act (the "Registration
Period") and (ii) take all lawful action such that each of (A) the Registration
Statement and any amendment thereto does not, when it becomes effective, contain
an untrue statement of a material fact or omit to state a material fact required

and (B) the Prospectus forming part of the Registration Statement, and any
amendment or supplement thereto, does not at any time during the Registration

misleading;

      (B) During the Registration Period, comply with the provisions of the

copies of the Prospectus and all amendments and supplements thereto and such
other documents, as such Investor may reasonably request in order to facilitate
the disposition of the Registrable Securities owned by such Investor;

      (D) (i) Register or qualify the Registrable Securities covered by the

Registration Period, (iii) take all such other lawful actions as may be
necessary to maintain such registrations and qualifications in effect at all
times during the Registration Period and (iv) take all such other lawful actions
reasonably necessary or advisable to qualify the Registrable Securities for sale

comfort letter to be so addressed), in customary form and covering matters of
the type customarily covered in "cold comfort" letters in connection with
secondary underwritten offerings;

shall be an "Affiliate" (as defined in Rule 2729(b)(1) of the rules and
regulations of the National Association of Securities Dealers, Inc. (the "NASD
Rules") (or any successor provision thereto)) of the Company or has a "conflict
of interest" (as defined in Rule 2720(b)(7) of the NASD Rules (or any successor
provision thereto)) and such broker-dealer shall underwrite, participate as a
member of an underwriting syndicate or selling group or assist in the
distribution of any Registrable Securities covered by the Registration

qualifications fees, printing and engraving fees, accounting fees, and the fees
and disbursements of counsel for the Company, and the reasonable fees of one
firm of counsel to the holders of a majority in interest of the Registrable
Securities shall be borne by the Company.

      6. Indemnification and Contribution

      (A) Indemnification by the Company. The Company shall indemnify and hold
harmless each Investor and each underwriter, if any, which facilitates the
disposition of Registrable Securities, and each of their respective officers and
directors and each person who controls such Investor or underwriter within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act
(each such person being sometimes hereinafter referred to as an "Indemnified
Person") from and against any losses, claims, damages or liabilities, joint or
several, to which such Indemnified Person may become subject under the
Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon an
untrue statement of a material fact contained in any Registration Statement or
an omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein, not misleading, or
arise out of or are based upon an untrue statement of a material fact contained
in any Prospectus or an omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading;
and the Company hereby agrees to reimburse such Indemnified Person for all
reasonable legal and other expenses incurred by them in connection with
investigating or defending any such action or claim as and when such expenses
are incurred; provided, however, that the Company shall not be liable to any
such Indemnified Person in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon (i) an untrue
statement or alleged untrue statement made in, or an omission or alleged
omission from, such

<PAGE>

Registration Statement or Prospectus in reliance upon and in conformity with
written information furnished to the Company by such Indemnified Person
expressly for use therein or (ii) in the case of the occurrence of an event of
the type specified in Section 3(E), the use by the Indemnified Person of an
outdated or defective Prospectus after the Company has provided to such
Indemnified Person an updated Prospectus correcting the untrue statement or
alleged untrue statement or omission or alleged omission giving rise to such
loss, claim, damage or liability.

      (B) Indemnification by Investors. Each Investor, severally and not jointly
with any other Investor, shall indemnify and hold harmless the Company, each of
its directors, each of its officers who have signed the Registration Statement,
each Person, if any, who controls the Company within the meaning of the
Securities Act, any underwriter and any other Investor selling securities under
such Registration Statement or any of such other Investor's partners, directors
or officers or any Person who controls such Investor within the meaning of the
Securities Act, against any losses, claims, damages or liabilities (joint or
several) to which the Company or any such director, officer, controlling person,
underwriter or other such Investor, partner, officer, director, member, employee
or agent or controlling person of such other Investor may become subject, in
each case to the extent (and only to the extent) that such loss results from
reliance upon written information furnished by such Investor expressly for use
in connection with such Registration Statement.

      (C) Notice of Claims, etc. Promptly after receipt by a party seeking
indemnification pursuant to this Section 6 (an "Indemnified Party") of written
notice of any investigation, claim, proceeding or other action in respect of
which indemnification is being sought (each, a "Claim"), the Indemnified Party
promptly shall notify the party against whom indemnification pursuant to this
Section 6 is being sought (the "Indemnifying Party") of the commencement
thereof; but the omission to so notify the Indemnifying Party shall not relieve
it from any liability that it otherwise may have to the Indemnified Party,
except to the extent that the Indemnifying Party is materially prejudiced and
forfeits substantive rights and defenses by reason of such failure. In
connection with any Claim as to which both the Indemnifying Party and the
Indemnified Party are parties, the Indemnifying Party shall be entitled to
assume the defense thereof. Notwithstanding the assumption of the defense of any
Claim by the Indemnifying Party, the Indemnified Party shall have the right to
employ separate legal counsel and to participate in the defense of such Claim,
and the Indemnifying Party shall bear the reasonable fees, out-of-pocket costs
and expenses of such separate legal counsel to the Indemnified Party if (and
only if): (x) the Indemnifying Party shall have agreed to pay such fees, costs
and expenses, (y) the Indemnified Party and the Indemnifying Party shall
reasonably have concluded that representation of the Indemnified Party by the
Indemnifying Party by the same legal counsel would not be appropriate due to
actual or, as reasonably determined by legal counsel to the Indemnified Party,
potentially differing interests between such parties in the conduct of the
defense of such Claim, or if there may be legal defenses available to the
Indemnified Party that are in addition to or disparate from those available to
the Indemnifying Party or (z) the Indemnifying Party shall have failed to employ
legal counsel reasonably satisfactory to the Indemnified Party within a
reasonable period of time after notice of the commencement of such Claim. If the
Indemnified Party employs separate legal counsel in circumstances other than as
described in clauses (x), (y) or (z) above, the fees, costs and expenses of such
legal counsel shall be borne exclusively by the Indemnified Party. Except as
provided above, the Indemnifying Party shall not, in connection with any Claim
in the same jurisdiction, be liable for the fees and expenses of more than one
firm of counsel for the

                                       10

<PAGE>

Indemnified Party (together with appropriate local counsel). The Indemnified
Party shall not, without the prior written consent of the Indemnifying Party
(which consent shall not unreasonably be withheld), settle or compromise any
Claim or consent to the entry of any judgment that does not include an
unconditional release of the Indemnifying Party from all liabilities with
respect to such Claim or judgment.

      (D) Contribution. If the indemnification provided for in this Section 6 is
unavailable to or insufficient to hold harmless an Indemnified Person under
subsection (A) above in respect of any losses, claims, damages or liabilities
(or actions in respect thereof) referred to therein, then each Indemnifying
Party shall contribute to the amount paid or payable by such Indemnified Party
as a result of such losses, claims, damages or liabilities (or actions in
respect thereof) in such proportion as is appropriate to reflect the relative
fault of the Indemnifying Party and the Indemnified Party in connection with the
statements or omissions which resulted in such losses, claims, damages or
liabilities (or actions in respect thereof), as well as any other relevant
equitable considerations. The relative fault of such Indemnifying Party and
Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by
such Indemnifying Party or by such Indemnified Party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission. The parties hereto agree that it would not be just
and equitable if contribution pursuant to this Section 6(D) were determined by
pro rata allocation (even if the Investors or any underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in this Section 6(D).
The amount paid or payable by an Indemnified Party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
shall be deemed to include any legal or other fees or expenses reasonably
incurred by such Indemnified Party in connection with investigating or defending
any such action or claim. No person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The obligations of the Investors and any underwriters in this
Section 6(D) to contribute shall be several in proportion to the percentage of
Registrable Securities registered or underwritten, as the case may be, by them
and not joint.

      (E) Notwithstanding any other provision of this Section 6, in no event
shall any (i) Investor be required to undertake liability to any person under
this Section 6 for any amounts in excess of the dollar amount of the proceeds to
be received by such Investor from the sale of such Investor's Registrable
Securities (after deducting any fees, discounts and commissions applicable
thereto) pursuant to any Registration Statement under which such Registrable
Securities are to be registered under the Securities Act and (ii) underwriter be
required to undertake liability to any Person hereunder for any amounts in
excess of the aggregate discount, commission or other compensation payable to
such underwriter with respect to the Registrable Securities underwritten by it
and distributed pursuant to the Registration Statement.

      (F) The obligations of the Company under this Section 6 shall be in
addition to any liability which the Company may otherwise have to any
Indemnified Person and the obligations of any Indemnified Person under this
Section 6 shall be in addition to any liability which such Indemnified Person
may otherwise have to the Company. The remedies provided in

                                       11

<PAGE>

this Section 6 are not exclusive and shall not limit any rights or remedies
which may otherwise be available to an indemnified party at law or in equity.

      7. Rule 144

      With a view to making available to the Investors the benefits of Rule 144
under the Securities Act or any other similar rule or regulation of the
Commission that may at any time permit the Investors to sell securities of the
Company to the public without registration ("Rule 144"), the Company agrees to
use its best efforts to:

      (1) comply with the provisions of paragraph (c) (1) of Rule 144 and

      (2) file with the Commission in a timely manner all reports and other
documents required to be filed by the Company pursuant to Section 13 or 15(d)
under the Exchange Act; and, if at any time it is not required to file such
reports but in the past had been required to or did file such reports, it will,
upon the request of any Investor, make available other information as required
by, and so long as necessary to permit sales of, its Registrable Securities
pursuant to Rule 144.

      8. Assignment

      The rights to have the Company register Registrable Securities pursuant to
this Agreement shall be automatically assigned by the Investors to any permitted
transferee of all or any portion of such Registrable Securities (or all or any
portion of the Debenture or Warrant of the Company which is convertible into
such securities) only if (a) the Investor agrees in writing with the transferee
or assignee to assign such rights, and a copy of such agreement is furnished to
the Company within a reasonable time after such assignment, (b) the Company is,
within a reasonable time after such transfer or assignment, furnished with
written notice of (i) the name and address of such transferee or assignee and
(ii) the securities with respect to which such registration rights are being
transferred or assigned, (c) immediately following such transfer or assignment,
the securities so transferred or assigned to the transferee or assignee
constitute Restricted Securities and (d) at or before the time the Company
received the written notice contemplated by clause (b) of this sentence the
transferee or assignee agrees in writing with the Company to be bound by all of
the provisions contained herein.

      9. Amendment and Waiver

      Any provision of this Agreement may be amended and the observance thereof
may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the Company
and Investors who hold a majority-in-interest of the Registrable Securities. Any
amendment or waiver effected in accordance with this Section 9 shall be binding
upon each Investor and the Company.

      10. Changes in Common Stock

      If, and as often as, there are any changes in the Common Stock by way of
stock split, stock dividend, reverse split, combination or reclassification, or
through merger, consolidation, reorganization or recapitalization, or by any
other means, appropriate adjustment

shall be made in the provisions hereof, as may be required, so that the rights
and privileges granted hereby shall continue with respect to the Common Stock as
so changed.

      11. Miscellaneous

      (A) A person or entity shall be deemed to be a holder of Registrable
Securities whenever such person or entity owns of record such Registrable
Securities. If the Company receives conflicting instructions, notices or
elections from two or more persons or entities with respect to the same
Registrable Securities, the Company shall act upon the basis of instructions,
notice or election received from the registered owner of such Registrable
Securities.

      (B) If, after the date hereof and prior to the Commission declaring the
Registration Statement to be filed pursuant to Section 2(a) effective under the
Securities Act, the Company grants to any Person any registration rights with
respect to any Company securities which are more favorable to such other Person
than those provided in this Agreement, then the Company forthwith shall grant
(by means of an amendment to this Agreement or otherwise) identical registration
rights to all Investors hereunder.

      (C) Except as may be otherwise provided herein, any notice or other
communication or delivery required or permitted hereunder shall be in writing
and shall be delivered personally, or sent by telecopier machine or by a
nationally recognized overnight courier service, and shall be deemed given when
so delivered personally, or by telecopier machine or overnight courier service
as follows:

      (3) if to any other Investor, at such address as such Investor shall have
provided in writing to the Company.

The Company, the Initial Investor or any Investor may change the foregoing
address by notice given pursuant to this Section 11(C).

      (D) Failure of any party to exercise any right or remedy under this
Agreement or otherwise, or delay by a party in exercising such right or remedy,
shall not operate as a waiver thereof.

      (E) This Agreement shall be governed by and interpreted in accordance with
the laws of the State of California. Each of the parties consents to the
jurisdiction of the federal courts whose districts encompass any part of the
City of San Diego or the state courts of the State of California sitting in the
City of San Diego in connection with any dispute arising under this Agreement
and hereby waives, to the maximum extent permitted by law, any objection
including any objection based on forum non conveniens, to the bringing of any
such proceeding in such jurisdictions.

      (F) Should any party hereto employ an attorney for the purpose of
enforcing or construing this Agreement, or any judgment based on this Agreement,
in any legal proceeding whatsoever, including insolvency, bankruptcy,
arbitration, declaratory relief or other litigation, the prevailing party shall
be entitled to receive from the other party or parties thereto reimbursement for
all reasonable attorneys' fees and all reasonable costs, including but not
limited to service of process, filing fees, court and court reporter costs,
investigative costs, expert witness fees, and the cost of any bonds, whether
taxable or not, and that such reimbursement shall be included in any judgment or
final order issued in that proceeding. The "prevailing party" means the party
determined by the court to most nearly prevail and not necessarily the one in
whose favor a judgment is rendered.

      (G) The remedies provided in this Agreement are cumulative and not
exclusive of any remedies provided by law. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants and restrictions set forth herein shall remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an alternative means to
achieve the same or substantially the same result as that contemplated by such
term, provision, covenant or restriction. It is hereby stipulated and declared
to be the intention of the parties that they would have executed the remaining
terms, provisions, covenants and restrictions without including any of such that
may be hereafter declared invalid, illegal, void or unenforceable.

      (H) The Company shall not enter into any agreement with respect to its
securities that is inconsistent with the rights granted to the holders of
Registrable Securities in this Agreement or otherwise conflicts with the
provisions hereof. Except as disclosed pursuant to the Securities Purchase
Agreement, the Company is not currently a party to any agreement granting any
registration rights with respect to any of its securities to any person which
conflicts with the Company's obligations hereunder or gives any other party the
right to include any securities in any Registration Statement filed pursuant
hereto, except for such rights and conflicts as have been irrevocably waived.
Without limiting the generality of the foregoing, without the written consent of
the holders of a majority in interest of the Registrable Securities, the Company
shall not grant to any person the right to request it to register any of its
securities under the Securities Act unless the rights so granted are subject in
all respect to the prior rights of the holders of Registrable Securities set
forth herein, and are not otherwise in conflict or inconsistent with the
provisions of this Agreement. The restrictions on the Company's rights to grant

registration rights under this paragraph shall terminate on the date the
Registration Statement to be filed pursuant to Section 2(A) is declared
effective by the Commission.

      (I) This Agreement, the Securities Purchase Agreement, the Debenture and
the Conversion Warrants Agreement, of even date herewith among the Company and
the Initial Investor constitute the entire agreement among the parties hereto
with respect to the subject matter hereof. There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein.
These Agreements supersede all prior agreements and undertakings among the
parties hereto with respect to the subject matter hereof.

      (J) Subject to the requirements of Section 8 hereof, this Agreement shall
inure to the benefit of and be binding upon the successors and assigns of each
of the parties hereto.

      (K) All pronouns and any variations thereof refer to the masculine,
feminine or neuter, singular or plural, as the context may require.

      (L) The headings in this Agreement are for convenience of reference only
and shall not limit or otherwise affect the meaning thereof.

      (M) The Company acknowledges that any failure by the Company to perform
its obligations under Section 3, or any delay in such performance, could result
in direct damages to the Investors and the Company agrees that, in addition to
any other liability the Company may have by reason of any such failure or delay,
the Company shall be liable for all direct damages caused by such failure or
delay.

      (N) This Agreement may be executed in counterparts, each of which shall be
deemed an original but both of which shall constitute one and the same
agreement. A facsimile transmission of this signed Agreement shall be legal and
binding on the parties hereto.

      IN WITNESS WHEREOF, the parties hereto have duly caused this Agreement to
be executed and delivered on the date first above written.

      SECTION 3.1 Conversion; Conversion Price; Valuation Event. (a) At the
option of the Holder, this Debenture may be converted, either in whole or in
part, up to the full Principal Amount hereof (in increments of $1,000 in
Principal Amount) into Common Shares (calculated as to each such conversion to
the nearest 1/100th of a share), at any time and from time to time on any
Business Day, subject to compliance with Section 3.2. The number of Common
Shares into which this Debenture may be converted is equal to (i) the Principal
Amount of the Debenture being converted at the Conversion Date (plus, if
mutually agreed by the parties, any accrued and unpaid interest on the Debenture
being converted through the Conversion Date) divided by (ii) the Conversion
Price. In addition, the Company shall pay to the Holder on the Conversion Date,
in cash, any accrued and unpaid interest on the Debenture being converted not
included in clause (i) of the immediately preceding sentence. The "Conversion
Price" shall be equal to the lesser of (i) $0.20, or (ii) eighty percent (80%)
of the average of the 5 lowest daily VWAPs during the twenty (20) Trading Days
prior to Holder's election to convert (a "Discount Multiplier"); provided, that
in the event the Registration Statement has not been declared effective by the
SEC by the Deadline or, if the Registration Statement has theretofore been
declared effective but is not thereafter effective, then the applicable Discount
Multiplier shall decrease by one and one-half percentage points (1.5%) for each
month or partial month occurring after the Deadline that the Registration
Statement is not effective. Such reduction of the Discount Multiplier shall be
rescinded 60 days after the Registration Statement is declared effective.

If the Holder elects to convert a portion of the Debenture and, on the day that
the election is made, the Conversion Price is below $0.025, the Company shall
have the right to prepay that portion of the Debenture that Holder elected to
convert, plus any accrued and unpaid interest, at 110% of such amount. In the
event that the Company elects to prepay that portion of the Debenture, Holder
shall have right to withdraw its Conversion Notice.

Beginning in the first full calendar month after the Registration Statement is
declared effective, Holder shall convert at least 5% of the face value of the
Debenture per calendar month into Common Shares of the Company, provided that
the Common Shares are available, registered and freely tradable. In the event
Holder breaches this provision, Holder shall not be entitled to collect interest
on the Debenture for that month. In the event the Holder breaches this provision
more than once in any twelve month period, at the option of the Company, this
Agreement, the Registration Rights Agreement, the Securities Purchase Agreement
and the associated warrants shall terminate, and the outstanding principal of
this Debenture, together with accrued but unpaid

Deadline or, if the Registration Statement has theretofore been declared
effective but is not thereafter effective, the following will apply in lieu of
any damages incurred by the Holder as a result thereof:

                  (i) The Holder may demand repayment of one hundred and

Company's Registration Statement being declared effective by the SEC or during
the period that the Company's Registration Statement is not effective, such
repayment to be made within three (3) business days of such demand. In the event
that the Debenture is so accelerated, in addition to the repayment of one
hundred and twenty-five percent (125%) of the Principal Amount together with
accrued interest as aforesaid, the Company shall immediately issue and pay, as
the case may be, to the Holder 50,000 Shares of Common Stock for each thirty
(30) day period, or portion thereof, during which the Principal Amount,
including interest thereon, remains unpaid, with the monthly payment amount to
increase to 65,000 Shares of Common Stock for each thirty (30) day period, or

thereof remains unconverted), shall cease and the Person and Persons in whose

liability thereon (except if and to the extent that any Principal Amount thereof
remains unconverted). No cash payment aggregating less than $1.00 shall be
required to be given unless specifically requested by the Holder.

            (b) If, at any time after the date of this Debenture, (i) the

transfer or otherwise dispose of all or substantially all its property, assets
or business to another Person, or effectuate a transaction or series of related

equal to the amount outstanding under this Debenture immediately prior to such
Fundamental Corporate Change. For purposes hereof, "common stock of the
successor or acquiring corporation" shall include stock of such corporation of
any class which is not preferred as to dividends or assets over any other class
of stock of such corporation and which is not subject to prepayment and shall

and the Company shall not have the obligation, to convert any portion of this
Debenture as shall cause such Holder to be deemed the beneficial owner of more
than 4.99% of the then Outstanding shares of Common Stock. If any court of
competent jurisdiction shall determine that the foregoing limitation is
ineffective to prevent a Holder from being deemed the beneficial owner of more
than 4.99% of the then Outstanding shares of Common Stock, then the Company
shall prepay such portion of this Debenture as shall cause such Holder not to be
deemed the beneficial owner of more than 4.99% of the then Outstanding shares of
Common

Stock. Upon such determination by a court of competent jurisdiction, the Holder
shall have no interest in or rights under such portion of the Debenture. Any and
all interest paid on or prior to the date of such determination shall be deemed
interest paid on the remaining portion of this Debenture held by the Holder.
Such prepayment shall be for cash at a prepayment price of one hundred and ten
percent (110%) of the Principal Amount thereof, together with all accrued and
unpaid interest thereon to the date of prepayment.

      SECTION 3.6 Surrender of Debentures. Upon any redemption of this Debenture
pursuant to Sections 3.2, 3.5 or 6.2, or upon maturity pursuant to Section 2.4,

principal executive offices or surrender the same to the Company at such address
by nationally recognized overnight courier. Payment of the redemption price or
the amount due on maturity specified in Section 2.4, shall be made by the
Company to the Holder against receipt of this Debenture (as provided in this
Section 3.5) by wire transfer of immediately available funds to such account(s)
as the Holder shall specify by written notice to the Company. If payment of such
redemption price is not made in full by the redemption date, or the amount due
on maturity is not paid in full by the Maturity Date, the Holder shall again
have the right to convert this Debenture as provided in Article 3 hereof or to
declare an Event of Default.
