of Rule 144.

        2.    Registration.    Unless otherwise objected to by the Commission,

review (the "Existing Registration Statement") covering the resale of all of the
Registrable Securities for an offering to be made on a continuous basis pursuant
to Rule 415. If the Commission objects to such inclusion, the Company agrees to
use commercially reasonable efforts to prepare and file with the Commission a
"Shelf" Registration Statement covering the resale of all Registrable Securities
within 5 days of the effective date of the Existing Registration Statement for
an offering to be made on a continuous basis pursuant to Rule 415. The
Registration Statement shall be on Form S-3 (unless the Company is not then
eligible to register for resale the Registrable Securities on Form S-3, in which
case such registration shall be on another appropriate form in accordance
herewith). Subject to the terms of this Agreement, the Company agrees to use
commercially reasonable efforts to cause the Registration Statement to be
declared effective under the Securities Act as promptly as reasonably
practicable after the filing thereof, and shall use commercially reasonable
efforts to keep such Registration Statement continuously effective under the
Securities Act until the date which is two years after the date that such
Registration Statement is declared effective by the Commission or such earlier
date when all Registrable Securities covered by such Registration Statement have
been sold or may be sold without volume restrictions pursuant to Rule 144(k) as
determined by the counsel to the Company pursuant to a written opinion letter to
such effect, addressed and acceptable to the Company's transfer agent (the
"Effectiveness Period").

        3.    Registration Procedures.    In connection with the Company's
registration obligations hereunder, the Company agrees to:

        (a)  Not less than three business days prior to the filing of the
Registration Statement or any related Prospectus or any amendment or supplement
thereto (excluding any document that would be incorporated or deemed to be
incorporated therein by reference and excluding in any case any information for
which an order granting confidential treatment thereof is in effect or has been
requested), furnish to each Holder copies of all such documents proposed to be
filed (other than those incorporated or deemed to be incorporated by reference
and excluding in any case any information for which an order granting
confidential treatment thereof is in effected has been requested), for review by
each Holder. The Company shall not file the Registration Statement or any such
Prospectus or any amendments or supplements thereto to which the Holders of a
majority of the Registrable Securities shall reasonably and in good faith
object, provided, the

2

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

Company is notified of such objection in writing no later than 2 business days
after the Holders have been so furnished copies of such documents.

        (b)  (i) Prepare and file with the Commission such amendments, including
post-effective amendments, to the Registration Statement and the Prospectus used
in connection therewith as may be necessary to keep the Registration Statement
continuously effective as to the applicable Registrable Securities for the
Effectiveness Period; (ii) cause the related Prospectus to be amended or
supplemented by any required Prospectus supplement (subject to the terms of this
Agreement), and as so supplemented or amended to be filed pursuant to Rule 424;
and (iii) respond as promptly as reasonably possible to any comments received
from the Commission with respect to the Registration Statement or any amendment
thereto and as promptly as reasonably possible provide the Holders true and
complete copies of all correspondence from and to the Commission relating to the
Holders.

        (c)  Notify the Holders of Registrable Securities to be sold (which
notice shall, pursuant to clauses (ii) through (vi) hereof shall be accompanied
by an instruction to suspend the use of the Prospectus until the requisite
changes have been made) as promptly as reasonably possible and (if requested by
any such Person) confirm such notice in writing as promptly as reasonably
possible following the day (i)(A) when a Prospectus or any Prospectus supplement
or post-effective amendment to the Registration Statement is proposed to be
filed; (B) when the Commission notifies the Company whether there will be a
"review" of such Registration Statement and whenever the Commission comments in
writing on such Registration Statement (the Company shall provide true and
complete copies thereof and all written responses thereto to each of the
Holders); and (C), with respect to the Registration Statement or any
post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus;
(iii) of the issuance by the Commission of any stop order suspending the
effectiveness of the Registration Statement covering any or all of the
Registrable Securities or the initiation of any Proceedings for that purpose;
(iv) of the receipt by the Company of any notification with respect to the
suspension of the qualification or exemption from qualification of any of the
Registrable Securities for sale in any jurisdiction, or the initiation or
threatening of any Proceeding for such purpose; (v) of the occurrence of any
event or passage of time that makes the financial statements included in the
Registration Statement ineligible for inclusion therein or any statement made in
the Registration Statement or Prospectus or any document incorporated or deemed
to be incorporated therein by reference untrue in any material respect or that
requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any 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, in light of the circumstances under which they were
made, not misleading; and (vi) the occurrence or existence of any pending
corporate development with respect to the Company that the Company believes may
be material and that, in the determination of the Company, makes it not in the
best interest of the Company to allow continued availability of the Registration
Statement or Prospectus.

        (d)  As promptly as reasonably practicable deliver to each Holder as
many copies of the Prospectus or Prospectuses (including each form of
prospectus) and each amendment or supplement thereto as such Persons may
reasonably request. Subject to the terms of this Agreement, the Company hereby
consents to the use of such Prospectus and each amendment or supplement thereto
by each of the selling Holders in connection with the offering and sale of the
Registrable Securities covered by such Prospectus and any amendment or
supplement thereto.

        (e)  Cooperate with the Holders to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be delivered to
a transferee pursuant to the Registration

3

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

Statement, which certificates, subject to the U.S. securities laws, shall be
free of all restrictive legends, and to enable such Registrable Securities to be
in such denominations and registered in such names as any such Holders may
request.

        (f)    Upon the occurrence of any event contemplated this Section 3, as
promptly as reasonably possible under the circumstances taking into account the
Company's good faith assessment of any adverse consequences to the Company and
its stockholders of the premature disclosure of such event, prepare a supplement
or amendment, including a post-effective amendment, to the Registration
Statement or a supplement to the related Prospectus or any document incorporated
or deemed to be incorporated therein by reference, and file any other required
document so that, as thereafter delivered, neither the Registration Statement
nor such Prospectus will contain an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading. If the Company notifies the Holders in accordance with clauses
(ii) through (v) of Section 3(d) above to suspend the use of the use of any
Prospectus until the requisite changes to such Prospectus have been made, or the
Company otherwise notifies the Holders of its election to suspend the
availability of the Registration Statement and Prospectus pursuant to
clause (vi) of Section 3(d), then the Holders shall suspend use of such
Prospectus. The Company will use commercially reasonable efforts to ensure that
the use of the Prospectus may be resumed as promptly as is practicable, except
that in the case of suspension of the availability of the Registration Statement
and Prospectus pursuant to clause (vi) of Section 3(d), the Company shall not be
required to take such action until such time as it shall determine that the
continued availability of the Registration Statement and Prospectus is no longer
not in the best interests of the Company.

        (g)  The Company may require, at any time prior to the third business
day prior to the date the Company files the Registration Statement or any
amendment or supplement thereto, each Holder to furnish to the Company a
statement as to the number of shares of Common Stock beneficially owned by such
Holder and the controlling person thereof and any other information reasonably
necessary for purposes of preparing and filing a Registration Statement, within
three business days of the Company's request.

        4.    Registration Expenses.    All fees and expenses incident to the
performance of or compliance with this Agreement by the Company shall be borne
by the Company whether or not any Registrable Securities are sold pursuant to
the Registration Statement. The fees and expenses referred to in the foregoing
sentence shall include, without limitation, (i) all registration and filing fees
(including, without limitation, fees and expenses (A) with respect to filings
required to be made with the Principal Market on which the Common Stock is then
listed for trading, and (B) in compliance with applicable state securities or
Blue Sky laws (including, without limitation, fees and disbursements of counsel
for the Company in connection with Blue Sky qualifications or exemptions of the
Registrable Securities and determination of the eligibility of the Registrable
Securities for investment under the laws of such jurisdictions as requested by
the Holders), (ii) printing expenses (including, without limitation, expenses of
printing certificates for Registrable Securities and of printing prospectuses
requested by the Holders), (iii) messenger, telephone and delivery expenses,
(iv) fees and disbursements of counsel for the Company and (v) fees and expenses
of all other Persons retained by the Company in connection with the consummation
of the transactions contemplated by this Agreement. Notwithstanding the
foregoing, in no event shall the Company be responsible for any broker or
similar commissions or, except to the extent provided for in the Transaction
Documents, any legal fees or other costs of the Holders.

4

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

        5.    Indemnification.    

        (a)    Indemnification by the Company.    The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, agents, brokers (including brokers who
offer and sell Registrable Securities as principal as a result of a pledge or
any failure to perform under a margin call of Common Stock), investment advisors
and employees of each of them, each Person who controls any such Holder (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange
Act) and the officers, directors, agents and employees of each such controlling
Person, to the fullest extent permitted by applicable law, from and against any
and all losses, claims, damages, liabilities, costs (including, without
limitation, costs of preparation and reasonable attorneys' fees) and expenses
(collectively, "Losses"), as incurred, arising out of or relating to any untrue
or alleged untrue statement of a material fact contained in the Registration
Statement, any Prospectus or any form of prospectus or in any amendment or
supplement thereto or in any preliminary prospectus, or arising out of or
relating to any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein (in the case of any
Prospectus or form of prospectus or supplement thereto, in light of the
circumstances under which they were made) not misleading, except to the extent,
but only to the extent, that (1) such untrue statements or omissions or alleged
untrue statements or omissions are based upon information regarding such Holder
furnished in writing to the Company by such Holder expressly for use therein, or
to the extent that such information relates to such Holder or such Holder's
proposed method of distribution of Registrable Securities and was reviewed and
expressly approved in writing by such Holder expressly for use in the
Registration Statement, such Prospectus or such form of Prospectus or in any
amendment or supplement thereto or (2) in the case of an occurrence of an event
of the type specified in Section 3(d)(ii)-(vi), the use by such Holder of an
outdated or defective Prospectus after the Company has notified such Holder in
writing that the Prospectus is outdated or defective and prior to the receipt by
such Holder of the Advice contemplated in Section 6(e). The Company shall notify
the Holders promptly of the institution, threat or assertion of any Proceeding
arising from or in connection with the transactions contemplated by this
Agreement of which the Company is aware.

        (b)    Indemnification by Holders.    Each Holder shall, severally and
not jointly, indemnify and hold harmless the Company, its directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses (as
determined by a court of competent jurisdiction in a final judgment not subject
to appeal or review) arising out of or based upon any untrue statement of a
material fact contained in any Registration Statement, any Prospectus, or any
form of prospectus, or in any amendment or supplement thereto, or arising out of
or based upon: (i) such Holder's failure to comply with the prospectus delivery
requirements of the Securities Act or (ii) any omission of a material fact
required to be stated therein or necessary to make the statements therein not
misleading to the extent, but only to the extent, that such untrue statement or
omission is contained in any information so furnished in writing by such Holder
to the Company specifically for inclusion in such Registration Statement or such
Prospectus or to the extent that (1) such untrue statements or omissions are
based upon information regarding such Holder furnished in writing to the Company
by such Holder expressly for use therein, or to the extent that such information
relates to such Holder or such Holder's proposed method of distribution of
Registrable Securities and was reviewed and expressly approved in writing by
such Holder expressly for use in the Registration Statement, such Prospectus or
such form of Prospectus or in any amendment or supplement thereto or (2) in the
case of an occurrence of an event of the type specified in
Section 3(d)(ii)-(vi), the use by such Holder of an outdated or defective
Prospectus after the Company has notified such Holder in writing that the

5

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

Prospectus is outdated or defective and prior to the receipt by such Holder of
the Advice contemplated in Section 6(e). In no event shall the liability of any
selling Holder hereunder be greater in amount than the dollar amount of the net
proceeds received by such Holder upon the sale of the Registrable Securities
giving rise to such indemnification obligation.

        (c)    Conduct of Indemnification Proceedings.    If any Proceeding
shall be brought or asserted against any Person entitled to indemnity hereunder
(an "Indemnified Party"), such Indemnified Party shall promptly notify the
Person from whom indemnity is sought (the " Indemnifying Party") in writing, and
the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all fees and expenses incurred in connection with defense thereof;
provided, that the failure of any Indemnified Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant to
this Agreement, except (and only) to the extent that such failure shall have
prejudiced the Indemnifying Party.

        An Indemnified Party shall have the right to employ separate counsel in
any such Proceeding and to participate in the defense thereof, but the fees and
expenses of such counsel shall be at the expense of such Indemnified Party or
Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a material conflict of interest is
likely to exist if the same counsel were to represent such Indemnified Party and
the Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and the expense of one such counsel for each
Holder shall be at the expense of the Indemnifying Party). The Indemnifying
Party shall not be liable for any settlement of any such Proceeding effected
without its written consent, which consent shall not be unreasonably withheld.
No Indemnifying Party shall, without the prior written consent of the
Indemnified Party, effect any settlement of any pending Proceeding in respect of
which any Indemnified Party is a party, unless such settlement includes an
unconditional release of such Indemnified Party from all liability on claims
that are the subject matter of such Proceeding.

        Subject to the terms of this Agreement, all fees and expenses of the
Indemnified Party (including reasonable fees and expenses to the extent incurred
in connection with investigating or preparing to defend such Proceeding in a
manner not inconsistent with this Section) shall be paid to the Indemnified
Party, as incurred, within ten business days of written notice thereof to the
Indemnifying Party (regardless of whether it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder; provided, that
the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such Indemnified Party is not entitled to indemnification
hereunder).

        (d)    Contribution.    If a claim for indemnification under
Section 5(a) or 5(b) is unavailable to an Indemnified Party (by reason of public
policy or otherwise), then each Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Losses, in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions, statements or omissions that
resulted in such Losses 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 any action in question,
including any untrue or alleged untrue statement of a material fact or omission
or alleged omission of a material

6

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

fact, has been taken or made by, or relates to information supplied by, such
Indemnifying Party or Indemnified Party, and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
action, statement or omission. The amount paid or payable by a party as a result
of any Losses shall be deemed to include, subject to the limitations set forth
in Section 5(c), any reasonable attorneys' or other reasonable fees or expenses
incurred by such party in connection with any Proceeding to the extent such
party would have been indemnified for such fees or expenses if the
indemnification provided for in this Section was available to such party in
accordance with its terms.

        The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 5(d), no Holder shall be required
to contribute, in the aggregate, any amount in excess of the amount by which the
proceeds actually received by such Holder from the sale of the Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission.

        The indemnity and contribution agreements contained in this Section are
in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

        6.    Miscellaneous.    

        (a)    Amendments and Waivers.    The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and the Holders of at least 50% of the then outstanding Registrable Securities.
Notwithstanding the foregoing, a waiver or consent to depart from the provisions
hereof with respect to a matter that relates exclusively to the rights of
Holders and that does not directly or indirectly affect the rights of other
Holders may be given by Holders of at least 50% of the Registrable Securities to
which such waiver or consent relates; provided, however, that the provisions of
this sentence may not be amended, modified, or supplemented except in accordance
with the provisions of the immediately preceding sentence.

        (b)    Compliance.    Each Holder covenants and agrees that it will
comply with the prospectus delivery requirements of the Securities Act as
applicable to it in connection with sales of Registrable Securities pursuant to
the Registration Statement.

        (c)    Discontinued Disposition.    Each Holder agrees by its
acquisition of such Registrable Securities that, upon receipt of a notice from
the Company of the occurrence of any event of the kind described in Sections
3(c), such Holder will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until such Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(f), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement. The Company may provide appropriate stop orders to
enforce the provisions of this paragraph.

        (d)    Notices.    Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be delivered as
set forth in the Purchase Agreements.

        (e)    Successors and Assigns.    This Agreement and the rights,
benefits and obligations hereunder shall not be transferred or assigned without
the written consent of the Company

7

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

        (f)    Counterparts.    This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original
and, all of which taken together shall constitute one and the same Agreement. In
the event that any signature is delivered by facsimile transmission, such
signature shall create a valid binding obligation of the party executing (or on
whose behalf such signature is executed) the same with the same force and effect
as if such facsimile signature were the original thereof.

        (g)    Governing Law.    All questions concerning the construction,
validity, enforcement and interpretation of this Agreement shall be governed by
and construed and enforced in accordance with the internal laws of the State of
California, without regard to the principles of conflicts of law thereof. Each
party hereby irrevocably submits to the exclusive jurisdiction of the state and
federal courts sitting in the County of San Diego, California, for the
adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably
waives, and agrees not to assert in any suit, action or proceeding, any claim
that it is not personally subject to the jurisdiction of any such court, that
such suit, action or proceeding is improper. Each party hereby irrevocably
waives personal service of process and consents to process being served in any
such suit, action or proceeding by mailing a copy thereof to such party at the
address in effect for notices to it under this Agreement and agrees that such
service shall constitute good and sufficient service of process and notice
thereof. Nothing contained herein shall be deemed to limit in any way any right
to serve process in any manner permitted by law. Each party hereto hereby
irrevocably waives, to the fullest extent permitted by applicable law, any and
all right to trial by jury in any legal proceeding arising out of or relating to
this Agreement or the transactions contemplated hereby. If either party shall
commence a Proceeding to enforce any provisions of this Agreement, then the
prevailing party in such Proceeding shall be reimbursed by the other party for
its attorneys fees and other costs and expenses incurred with the investigation,
preparation and prosecution of such Proceeding.

        (h)    Cumulative Remedies.    The remedies provided herein are
cumulative and not exclusive of any remedies provided by law.

        (i)    Severability.    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 reasonable 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.

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

        (k)    Independent Nature of Purchasers' Obligations and Rights.    The
obligations of each Purchaser hereunder is several and not joint with the
obligations of any other Purchaser hereunder, and no Purchaser shall be
responsible in any way for the performance of the obligations of any other
Purchaser hereunder. Nothing contained herein or in any other agreement or
document delivered at any closing, and no action taken by any Purchaser pursuant
hereto or thereto, shall be deemed to constitute the Purchasers as a
partnership, an association, a joint venture or any other kind of entity, or
create a presumption that the Purchasers are in any way acting in concert with
respect to such obligations or the transactions contemplated by this Agreement.
Each Purchaser shall be entitled to protect and enforce its rights, including
without limitation the rights arising out of this Agreement, and it shall not be
necessary for any other Purchaser to be joined as an additional party in any
proceeding for such purpose.
