Shelf Registration.

The Company shall:
as promptly as practicable, but not later than 30 days after the earliest date
of original issuance of any of the Notes and Warrants (the "Shelf Filing
Deadline"), cause to be filed with the Commission a registration statement on
Form S-3 pursuant to Rule 415 under the Securities Act (the "Shelf Registration
Statement"), which Shelf Registration Statement shall provide for the offer and
sale of all Registrable Shares held by Holders that have provided the
information required pursuant to the terms of Section 2(b) hereof;
use its best efforts to cause the Shelf Registration Statement to be declared
effective by the Commission as promptly as practicable, but not later than 90
days after the earliest date of original issuance of any of the Notes and
Warrants or, in the event of a review by the Commission, 120 days (either the
"Effectiveness Target Date"); and

use its best efforts to keep the Shelf Registration Statement continuously
effective, supplemented and amended as required by the provisions of Section
4(b) hereof (subject to the right of the Company to suspend the use of the Shelf
Registration Statement by delivery of a Suspension Notice in accordance with
Section 4(b)(i) hereof) to the extent necessary to ensure that it (A) is
available for resales of Registrable Shares by the Holders of such Registrable
Shares entitled, subject to Section 2(b), to the benefit of this Agreement and
(B) conforms with the requirements of this Agreement and the Securities Act and
the rules and regulations of the Commission promulgated thereunder as announced
from time to time, for a period (the "Effectiveness Period") ending on the date
there are no longer any Registrable Shares.

No Holder of Registrable Shares may include any of its Registrable Shares in the
Shelf Registration Statement pursuant to this Agreement unless such Holder
furnishes to the Company in writing, prior to or on the 10th Business Day after
such Holder's receipt from the Company of the Holder Questionnaire (or, in the
case of a Holder that is a transferee of Registrable Shares, prior to or on the
earlier of (i) the 20th Business Day after the completion of such transfer to
the transferee and (ii) 9:00 a.m., California time, on the second Business Day
before the effectiveness of the Shelf Registration Statement) (such applicable
deadline, the "Questionnaire Deadline"), such information regarding the Holder
and the distribution of Registrable Shares as the Company may reasonably request
for use in connection with the Shelf Registration Statement or Prospectus or
preliminary Prospectus included therein and in any application to be filed with
or under state securities laws (the form of which request is attached as
Appendix A hereto regarding the sale of the Notes and Warrants to the Purchasers
- ----------
and is referred to herein as the "Holder Questionnaire"). In connection with all
requests for information from Holders of Registrable Shares with respect to
inclusion of Registrable Shares in the Shelf Registration Statement, the Company
shall notify such Holders of the requirements set forth in the preceding
sentence. The Company agrees and undertakes that (i) it shall distribute a
Holder Questionnaire


                                                                               3

no later than 25 Business Days prior to the initial effectiveness of the Shelf
Registration Statement to each Holder at its Registered Address and (ii) upon
the request of any Holder made prior to 9:00 a.m., California time, on the
second Business Day before the initial effectiveness of the Shelf Registration
Statement, the Company shall also distribute a Holder Questionnaire to such
Holder at the address set forth in any request by such Holder. Holders that do
not complete the Holder Questionnaire and timely deliver it to the Company shall
not be named as selling securityholders in the Prospectus or preliminary
Prospectus included in the Shelf Registration Statement and therefore shall not
be permitted to sell any Registrable Shares pursuant to the Shelf Registration
Statement. Notwithstanding the foregoing, upon request from a Holder that did
not return a Holder Questionnaire on a timely basis because it was a subsequent
transferee of Registrable Shares after the company distributed the Holder
Questionnaire, (i) the Company shall distribute a Holder Questionnaire to such
Holder at the address set forth in the request and (ii) upon receipt of a
properly completed Holder Questionnaire from such Holder, the Company shall use
its reasonable efforts to name such Holder as a selling securityholder by means
of a pre-effective amendment or, if permitted by the Commission, by means of a
Prospectus supplement to the Shelf Registration Statement; provided, however,
                                                           --------  -------
that the Company shall have no obligation to pay Liquidated Damages to such
Holder for its failure to file a pre-effective amendment or Prospectus
supplement. Each Holder as to which the Shelf Registration Statement is being
effected agrees to furnish promptly to the Company all information required to
be disclosed in order to make information previously furnished to the Company by
such Holder not materially misleading.

Liquidated Damages.
If:
the Shelf Registration Statement is not filed with the Commission prior to or on
the Shelf Filing Deadline;
the Shelf Registration Statement has not been declared effective by the
Commission prior to or on the Effectiveness Target Date;
except as provided in Section 4(b)(i) hereof, the Shelf Registration Statement
is filed and declared effective but, during the Effectiveness Period, shall
thereafter cease to be effective or usable or the Prospectus ceases to be
usable, in either case, in connection with resales of Registrable Shares without
being succeeded within five Business Days by a post-effective amendment to the
Shelf Registration Statement, a supplement to the Prospectus or a report filed
with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the
Exchange Act that cures such failure and, in the case of a post-effective
amendment, is itself immediately declared effective; or
prior to or on the 30th day, as the case may be, of any Suspension Period, such
suspension has not been terminated or the Suspension Periods exceed an aggregate
of 30 days in any 360-day period,

(each such event referred to in the foregoing clauses (i) through (iv), a
"Registration Default"), the Company hereby agrees to pay damages, ("Liquidated
Damages"), with respect to the Registrable Shares from and including the day
following the Registration Default to, but excluding, the earlier of (1) the day
on which the Registration Default has been cured and (2) the date the Shelf
Registration Statement is no longer required to be kept effective, accruing:


                                                                               4

in respect of Notes that are convertible into Registrable Shares, to each Holder
of such Notes at a rate equal to 1.5% per month (pro rated for partial months)
of the principal amount of the Notes; in respect of Warrants, that are
exercisable for Registrable Shares, to each Holder of such Warrants at a rate
equal to 1.5% per month (pro rated for partial months) of the principal amount
of the Notes, issued in connection with such Warrant; and in respect of any
shares of Common Stock that have been issued upon conversion of the Notes or
exercise of Warrants and that are Registrable Shares, to each Holder of such
Registrable Shares at a rate equal to 1.5% per month (pro rated for partial
months) of the principal amount of the Notes (i) upon conversion of which such
Registrable Shares were issued or (ii) relating to the Warrants upon exercise of
which such Registrable Shares were issued, as the case may be; provided,
however, that the Liquidated Damages set forth in clauses (A), (B) and (C) above
shall not be cumulative and no Holder shall accrue Liquidated Damages at a rate
in excess of 1.5% per month of the principal amount of the Notes.

All accrued Liquidated Damages shall be paid in arrears by the Company on each
Liquidated Damages Payment Date in the same manner as the payment of interest on
the Notes to each Holder that held securities with respect to which Liquidated
Damages accrued pursuant to Section 3(a).  Upon the earlier of the cure of all
Registration Defaults or the termination of the Company's obligation to keep the
Shelf Registration Statement effective, the accrual of Liquidated Damages
pursuant to this Section 3 will cease.  The Company agrees to deliver any
notices, certificates and other documents contemplated by the Notes and Warrants
in connection with the payment of Liquidated Damages.

Notwithstanding any other provision of this Agreement, no Liquidated Damages
shall accrue as to any Registrable Shares that are issuable upon conversion of
any Notes or upon exercise of any Warrants, as the case may be, or any
outstanding Registrable Shares from and after the earlier of (i) the date such
security no longer is convertible into or exercisable for Registrable Shares or
no longer is a Registrable Share (without regard to any limitation on
conversions or exercises), as the case may be, and (ii) the date of expiration
of the Effectiveness Period.  All obligations of the Company set forth in this
Section 3 that are outstanding with respect to any Registrable Shares that are
issuable upon conversion of any Notes or upon exercise of any Warrants, as the
case may be, any outstanding Registrable Shares or any Registrable Share at the
time such security ceases to be a Registrable Share shall survive until such
time as all such obligations with respect thereto shall have been satisfied in
full.

The parties hereto agree that the Holders of Registrable Shares (including
Holders of Notes or Warrants convertible into or exercisable for Registrable
Shares) will suffer damages, and that it would not be feasible to ascertain the
extent of such damages with precision, if a Registration Default were to occur.
The parties hereto further agree that the Liquidated Damages provided for in
this Section 3 constitute a reasonable estimate of the damages that may be
incurred by Holders of Registrable Shares (including holders of Notes or
Warrants convertible into or exercisable for Registrable Shares) by reason of a
Registration Default.  Therefore, the parties hereto agree that the sole damages
payable for a violation of the terms of this Agreement with respect to which
Liquidated Damages is expressly provided for (including any non-compliance with
a covenant that results, directly or indirectly, in a Registration Default)
shall be such Liquidated Damages; provided, however, that the Holders of
                                  --------  -------
Registrable Shares may seek other non-monetary remedies, including a decree of
specific performance or other injunctive relief.  In the event of any conflict
of the provisions this Agreement and Section 6 of the Notes, Section 6 of the
Notes shall control.

Registration Procedures.


                                                                               5

In connection with the Shelf Registration Statement, the Company shall comply
with all the provisions of Section 4(b) hereof and shall use its best efforts to
effect such registration to permit the sale of the Registrable Shares, and
pursuant thereto, shall prepare and file with the Commission a Shelf
Registration Statement relating to the registration of the Registrable Shares on
Form S-3.  The Company represents and warrants that it currently meets the
requirements for use of Form S-3 for registration of the resale of the
Registrable Shares, and has no actual knowledge of any facts which would
reasonably cause the Company to fail to meet such requirements.   In the event
that Form S-3 is not available for the registration of the resale of Registrable
Shares hereunder, the Company shall (i) register the resale of the Registrable
Shares on another appropriate form, reasonably acceptable to a Majority of
Holders and (ii) undertake to register the Registrable Shares on Form S-3 as
soon as such form is available, provided that the Company shall use its best
efforts to maintain the effectiveness of the Registration Statement then in
effect until such time as a Registration Statement on Form S-3 covering the
Registrable Shares has been declared effective by the SEC.

     The Majority of Holders shall have the right to select one legal counsel to
review and oversee any offering pursuant to this Section 4 ("Legal Counsel"),
which shall be Katten Muchin Zavis Rosenman or such other counsel thereafter as
designated by a Majority of Holders. The Company shall reasonably cooperate with
Legal Counsel in performing the Company's obligations under this Agreement.

     In connection with the Shelf Registration Statement and any Prospectus
required by this Agreement to permit the sale or resale of Registrable Shares,
the Company shall:


                                                                               6

Subject to any notice by the Company in accordance with this Section 4(b) of the
existence of any fact or event of the kind described in Section 4(b)(iii)(D) and
the Company's right to invoke a Suspension Period in the manner described in
this Section 4(b)(i), use commercially reasonable efforts to keep the Shelf
Registration Statement continuously effective during the Effectiveness Period;
upon the occurrence of any event that would cause the Shelf Registration
Statement or the Prospectus contained therein to (A) contain a material
misstatement or omission or (B) not be effective and usable for resale of
Registrable Shares during the Effectiveness Period, unless a Suspension Period
is then in effect, the Company shall file promptly an appropriate amendment to
the Shelf Registration Statement, a supplement to the Prospectus or a report
filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the
Exchange Act, in the case of clause (A), correcting any such misstatement or
omission, and, in the case of either clause (A) or (B), use commercially
reasonable efforts to cause such amendment to be declared effective and the
Shelf Registration Statement and the related Prospectus to become usable for
their intended purposes as soon as practicable thereafter.  Notwithstanding the
foregoing, the Company may suspend the effectiveness of the Shelf Registration
Statement by written notice to the Holders for a period, together with any
period during which the effectiveness of the Shelf Registration Statement is
suspended by a stop order issued by the Commission, not to exceed an aggregate
of 30 days in any 360-day period (each such period, a "Suspension Period");
provided that no Suspension Period shall occur during the 10 Trading Days (as
defined in the Notes) following any (x) Interest Payment Date (as defined in the
Noes) as to which the Company has elected to pay interest on the Notes by
delivery of shares of Common Stock, or (y) Automatic Mandatory Exercise Date (as
defined in the Warrants); and provided further that the Company shall promptly
notify each Holder in writing of the date on which the Suspension Period will
begin and the date on which the Suspension Period ends, and shall not be
obligated to pay Liquidated Damages in such Suspension Period if:
                    (x) an event occurs and is continuing as a result of which
                    the Shelf Registration Statement, the Prospectus, any
                    amendment or supplement thereto, or any document
                    incorporated by reference therein would, in the Company's
                    reasonable judgment, 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 not misleading; and
                    (y) the Company reasonably determines in good faith that the
                    disclosure of such event at such time would have a material
                    adverse effect on the Company and its subsidiaries taken as
                    a whole;

          The Company shall permit Legal Counsel to review and comment upon a
     Shelf Registration Statement and all amendments and supplements thereto at
     least five business days prior to their filing with the Comission, and not
     file any document in a form to which Legal Counsel reasonably objects in a
     timely manner. The Company shall not submit a request for acceleration of
     the effectiveness of a Shelf Registration Statement or any amendment or
     supplement thereto without the prior approval of Legal Counsel, which
     consent shall not be unreasonably withheld. The Company shall furnish to
     Legal Counsel without charge (i) any correspondence from the Commission or
     the staff of the Commission to the Company or its representatives relating
     to any Shelf Registration Statement, (ii) promptly after the same is
     prepared and filed with the Commission, one copy of any Shelf Registration
     Statement and any amendment(s) thereto, including financial statements and
     schedules, all documents incorporated therein by reference and


                                                                               7

     all exhibits and (iii) upon the effectiveness of any Shelf Registration
     Statement, one copy of the prospectus included in such Shelf Registration
     Statement and all amendments and supplements thereto.

          In the event that the number of shares available under (i) the Shelf
     Registration Statement together with (ii) any registration statements filed
     pursuant to this Section 4(a) is insufficient to cover the resale of 100%
     of the Registrable Shares , the Company shall amend any such Registration
     Statement, or file a new Registration Statement (on the short form
     available therefor, if applicable), or both, so as to cover at least 100%
     of the Registrable Shares calculated as of the trading day immediately
     preceding the date of the filing of such amendment or new Registration
     Statement), in each case, as soon as practicable, but in any event not
     later than 15 Business Days after the necessity therefor arises. The
     Company shall use its best efforts to cause such amendment and/or new
     Registration Statement to become effective as soon as practicable following
     the filing thereof.

Prepare and file with the Commission such amendments and post-effective
amendments to the Shelf Registration Statement as may be necessary to keep the
Shelf Registration Statement effective during the Effectiveness Period; cause
the Prospectus to be supplemented by any required Prospectus supplement, and as
so supplemented to be filed pursuant to Rule 424 (it being understood that the
Company shall not be required to file a Prospectus supplement pursuant to Rule
424(b) with respect to any Holder that failed to submit their Holder
Questionnaire by the Questionnaire Deadline) under the Securities Act, and to
comply fully with the applicable provisions of Rules 424 and 430A under the
Securities Act in a timely manner; and comply with the provisions of the
Securities Act with respect to the disposition of all Registrable Shares covered
by the Shelf Registration Statement during the applicable period in accordance
with the intended method or methods of distribution by the sellers thereof set
forth in the Shelf Registration Statement or a supplement to the Prospectus.
Advise in writing the underwriter(s), if any, and each of the selling Holders
(which writing shall not contain any material non-public information) promptly
at its Registered Address of each of the following:
when the Prospectus or any Prospectus supplement or any post-effective amendment
to the Shelf Registration Statement has been filed, and, with respect to the
Shelf Registration Statement or any post-effective amendment thereto, when the
same has become effective, any request by the Commission for amendments to the
Shelf Registration Statement or amendments or supplements to the Prospectus or
for additional information relating thereto, the issuance by the Commission of
any stop order suspending the effectiveness of the Shelf Registration Statement
under the Securities Act or of the suspension by any state securities commission
of the qualification of the Registrable Shares for offering or sale in any
jurisdiction, or the initiation of any proceeding for any of the preceding
purposes, or the existence of any fact or the happening of any event, during the
Effectiveness Period (but not as to the substance of any such fact or event),
that makes any statement of a material fact made in the Shelf Registration
Statement, the Prospectus, any amendment or supplement thereto, or any document
incorporated by reference therein untrue, or that requires the making of any
additions to or changes in the Shelf Registration Statement or the Prospectus in
order to make the statements therein not misleading (provided, however, that no
                                                     --------  -------
notice by the Company shall be required pursuant to this clause (D) in the event
that the Company either contemporaneously files a prospectus supplement to
update the Prospectus or a Form 8-K or other appropriate Exchange


                                                                               8

Act report that is incorporated by reference into the Shelf Registration
Statement, which, in either case, contains the requisite information with
respect to such material event that results in such Shelf Registration Statement
no longer containing any such untrue or misleading statements).
          If at any time the Commission shall issue any stop order suspending
          the effectiveness of the Shelf Registration Statement, or any state
          securities commission or other regulatory authority shall issue an
          order suspending the qualification or exemption from qualification of
          the Registrable Shares under state securities or Blue Sky laws, the
          Company shall use its best efforts to promptly obtain the withdrawal
          or lifting of such order and will provide to each Holder at its
          Registered Address who is named in the Shelf Registration Statement
          prompt notice (which notice shall not contain any material non-public
          information) of the withdrawal of any such order. Within five (5)
          Business Days after the Shelf Registration Statement which includes
          the Registrable Shares is ordered effective by the Commission, the
          Company shall cause legal counsel for the Company to deliver to the
          transfer agent for such Registrable Shares (with copies to the
          Investors whose Registrable Shares are included in such Shelf
          Registration Statement) confirmation that the Shelf Registration
          Statement has been declared effective by the Commission in the form
          attached as hereto as Exhibit A.
                                ---------
If requested by any selling Holders or the underwriter(s), if any, incorporate
in the Shelf Registration Statement or Prospectus, pursuant to an amendment
prior to effectiveness if necessary, such information as such selling Holders
and underwriter(s), if any, may reasonably request to have included therein,
including, without limitation information relating to the "Plan of Distribution"
of the Registrable Shares as specified by such Holder in such Holder
Questionnaire to be delivered prior to the Questionnaire Deadline.
Furnish to each selling Holder at its Registered Address and each of the
underwriter(s), if any, upon their request, without charge, at least one copy of
the Shelf Registration Statement, as first filed with the Commission, and of
each amendment thereto (and any documents incorporated by reference therein or
exhibits thereto (or exhibits incorporated in such exhibits by reference) as
such Person may request).
Deliver to each selling Holder at its Registered Address and each of the
underwriter(s), if any, without charge, as many copies of the Prospectus
(including each preliminary Prospectus) and any amendment or supplement thereto
as such Persons reasonably may request; subject to any notice by the Company in
accordance with this Section 4(b) of the existence of any fact or event of the
kind described in Section 4(b)(iii)(D), the Company hereby consents to the use
of the Prospectus and any amendment or supplement thereto by each of the selling
Holders in connection with the offering and the sale of the Registrable Shares
covered by the Prospectus or any amendment or supplement thereto.
In connection with an Underwritten Offering, the Company shall: upon request,
furnish to each underwriter, if any, in such substance and scope as they may
reasonably request and as are customarily made by issuers to underwriters in
primary underwritten offerings for selling security holders, upon the date of
closing of any sale of Registrable Shares in an Underwritten Registration:

a certificate, dated the date of such closing, signed by the Chief Financial
Officer of the Company confirming, as of the date thereof, the matters
customarily covered in an officer's certificate to underwriters in connection
with underwritten offerings of securities;

opinions, each dated the date of such closing, of counsel to the Company
covering such of the matters as are customarily covered in legal opinions to
underwriters in connection with underwritten offerings of securities; and


                                                                               9

customary comfort letters, dated the date of such closing, from the Company's
independent accountants (and from any other accountants whose report is
contained or incorporated by reference in the Shelf Registration Statement) in
the customary form of and covering matters of the type customarily covered in
comfort letters to underwriters in connection with underwritten offerings of
securities; and


                                                                              10

deliver such other documents and certificates as may be reasonably requested by
such parties to evidence compliance with clause (A) above and with any customary
conditions contained in the underwriting agreement or other agreement entered
into by the selling Holders pursuant to this clause (vii).
Before any public offering of Registrable Shares, cooperate with the selling
Holders, the underwriter(s), if any, and their counsel in connection with the
registration and qualification of the Registrable Shares under the securities or
Blue Sky laws of such jurisdictions in the United States as the selling Holders
or underwriter(s), if any, may reasonably request and do any and all other acts
or things necessary or advisable to enable the disposition in such jurisdictions
of the Registrable Shares covered by the Shelf Registration Statement; provided,
                                                                       --------
however, that the Company shall not be required (A) to register or qualify as a
- -------
foreign corporation or a dealer of securities where it is not now so qualified
or to take any action that would subject it to service of process in any
jurisdiction where it is not now so subject or (B) to subject itself to taxation
in any such jurisdiction if it is not now so subject.
Cooperate with the selling Holders and underwriter(s), if any, to facilitate the
timely preparation and delivery of certificates representing Registrable Shares
to be sold and not bearing any restrictive legends (unless required by
applicable securities laws); and enable such Registrable Shares to be in such
denominations and registered in such names as the Holders may request at least 2
Business Days before any sale of Registrable Shares.
Use commercially reasonable efforts to cause the Registrable Shares covered by
the Shelf Registration Statement to be registered with or approved by such other
U.S. governmental agencies or authorities as may be necessary to enable the
seller or sellers thereof to consummate the disposition of such Registrable
Shares.
Subject to Section 4(b)(i) hereof, if any fact or event contemplated by Section
4(b)(iii)(D) hereof shall exist or have occurred, use its best efforts to
prepare a supplement or post-effective amendment to the Shelf Registration
Statement or related Prospectus or any document incorporated therein by
reference or file any other required document so that, as thereafter delivered
to the purchasers of Registrable Shares, the 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, in light of
the circumstances under which they are made, not misleading.
Cooperate and assist in any filings required to be made with the NASD and in the
performance of any due diligence investigation by any underwriter that is
required to be retained in accordance with the rules and regulations of the
NASD.
Otherwise use commercially reasonable efforts to comply with all applicable
rules and regulations of the Commission and all reporting requirements under the
rules and regulations of the Exchange Act and to file all reports required to be
filed by the Company with the Commission so as to maintain the Company's
eligibility for the use of Form S-3 for registration of Registrable Shares.
Cause all Common Stock covered by the Shelf Registration Statement to be listed
or quoted, as the case may be, on each securities exchange or automated
quotation system on which Common Stock is then listed or quoted.
Respond promptly to any and all comments made by the staff of the Commission to
the Shelf Registration Statement required by Section 2(a), and shall submit to
the Commission, before the close of business on the Business Day immediately
following the Business Day on which the Company learns (either by telephone or
in writing) that the staff of the Commission has no


                                                                              11

further comments on such Shelf Registration Statement, as the case may be, a
request for acceleration of the effectiveness of such Shelf Registration
Statement to a time and date as soon as practicable.


Each Holder agrees by acquisition of any Note, Warrant or share of Common Stock
issued upon conversion or exercise thereof, as applicable, that, upon receipt of
any notice (a "Suspension Notice") from the Company of the existence of any fact
of the kind described in Section 4(b)(iii)(D) hereof, such Holder will, and will
use commercially reasonable efforts to cause any underwriter(s) in an
Underwritten Offering to, forthwith discontinue disposition of Registrable
Shares pursuant to the Shelf Registration Statement and any use of the
associated Prospectus until:
such Holder has received copies of the supplemented or amended Prospectus
contemplated by Section 4(b)(xi) hereof; or
such Holder is advised in writing by the Company that the use of the Prospectus
may be resumed, and has received copies of any additional or supplemental
filings that are part of or incorporated by reference in the Prospectus.

Each Holder agrees to keep the receipt of a Suspension Notice and its contents
confidential.  If so directed by the Company, each Holder will deliver to the
Company (at the Company's expense) all copies, other than permanent file copies
then in such Holder's possession, of the Prospectus covering such Registrable
Shares that was current at the time of receipt of such Suspension Notice.

Registration Expenses.  All expenses incident to the Company's performance of or
compliance with this Agreement shall be borne by the Company regardless of
whether a Shelf Registration Statement becomes effective, including, without
limitation:
all registration and filing fees and expenses (including filings made with the
NASD);
all fees and expenses of compliance with federal securities and state Blue Sky
or securities laws;
all expenses of printing (including printing of Prospectuses and certificates
for the Common Stock to be issued upon conversion of the Notes and exercise of
the Warrants) and the Company's expenses for messenger and delivery services and
telephone;
all fees and disbursements of counsel to the Company and all transfer agent
fees;
all application and filing fees in connection with listing (or authorizing for
quotation) the Common Stock on a national securities exchange or automated
quotation system pursuant to the requirements hereof; and
all fees and disbursements of independent certified public accountants of the
Company.

The Company shall bear its internal expenses (including, without limitation, all
salaries and expenses of its officers and employees performing legal, accounting
or other duties), the expenses of any annual audit and the fees and expenses of
any Person, including special experts, retained by the Company.  Notwithstanding
the foregoing, the Holders of the Registrable Shares being registered shall pay
all agency fees and commissions and underwriting discounts and commissions
attributable to the sale of such Registrable Shares and the fees and
disbursements of any counsel or other advisors or experts retained by such
Holders (severally and jointly), other than the counsel and experts that
represent the Company specifically referred to above.


                                                                              12

Reports Under the Exchange Act.  With a view to making available to the Holders
the benefits of Rule 144 promulgated under the Securities Act or any other
similar rule or regulation of the Commission that may at any time permit the
Purchasers to sell securities of the Company to the public without registration
("RULE 144"), the Company agrees to:
          (a) make and keep public information available, as those terms are
understood and defined in Rule 144;
          (b) file with the Commission in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act
so long as the Company remains subject to such requirements (it being understood
that nothing herein shall limit the Company's obligations under Section 4(c) of
the Securities Purchase Agreement) and the filing of such reports and other
documents as required for the applicable provisions of Rule 144; and

          (c) furnish to each Holder so long as such Holder owns Registrable
Shares, promptly upon request, (i) a written statement by the Company that it
has complied with the reporting requirements of Rule 144, the Securities Act and
the Exchange Act, (ii) a copy of the most recent annual or quarterly report of
the Company and such other reports and documents so filed by the Company, and
(iii) such other information as may be reasonably requested to permit the
investors to sell such securities pursuant to Rule 144 without registration.

Indemnification and Contribution.

The Company shall indemnify and hold harmless each Holder, such Holder's
officers, directors, agents, advisors, investment managers, attorneys and
employees and each person, if any, who controls such Holder within the meaning
of the Securities Act (each, an "Indemnified Holder"), from and against any
loss, claim, damage or liability, joint or several, or any action in respect
thereof (including, but not limited to, any loss, claim, damage, liability or
action relating to resales of the Registrable Shares), to which such Indemnified
Holder may become subject, insofar as any such loss, claim, damage, liability or
action arises out of, or is based upon:
any untrue statement or alleged untrue statement of a material fact contained in
(A) the Shelf Registration Statement or Prospectus or any amendment or
supplement thereto or (B) any blue sky application or other document or any
amendment or supplement thereto prepared or executed by the Company (or based
upon written information furnished by or on behalf of the Company expressly for
use in such blue sky application or other document or amendment on supplement)
filed in any jurisdiction specifically for the purpose of qualifying any or all
of the Registrable Shares under the securities law of any state or other
jurisdiction (such application or document being hereinafter called a "Blue Sky
Application"); or
the omission or alleged omission to state therein any material fact required to
be stated therein or necessary to make the statements therein (in the case of a
Prospectus or any amendment or supplement thereto, in the light of the
circumstances under which they were made) not misleading,

and shall reimburse each Indemnified Holder promptly upon demand for any legal
or other expenses reasonably incurred by such Indemnified Holder in connection
with investigating or defending or preparing to defend against any such loss,
claim, damage, liability or action as such expenses are incurred; provided,
                                                                  --------
however, that the Company shall not be liable in any such case to the extent
- -------
that any such loss, claim, damage, liability or action arises out of, or is
based upon, any untrue statement or


                                                                              13

alleged untrue statement or omission or alleged omission made in the Shelf
Registration Statement or Prospectus or amendment or supplement thereto or Blue
Sky Application in reliance upon and in conformity with the Holder Questionnaire
furnished to the Company by or on behalf of such Holder (or its related
Indemnified Holder); provided, further, that the Company shall not be liable to
                     --------  -------
any Indemnified Holder under the indemnity agreement in this subsection (a) with
respect to any preliminary Prospectus to the extent that any such loss, claim,
damage or liability of such Indemnified Holder results from the fact that such
Indemnified Holder sold Registrable Shares to a Person as to whom it shall be
established that there was not sent or given, at or prior to the written
confirmation of such sale, a copy of the final Prospectus in any case where such
delivery is required by the Securities Act if the Company had previously
furnished copies thereof in sufficient quantities to such Indemnified Holder and
the loss, claim, damage or liability of such Indemnified Holder results from an
untrue statement or omission of a material fact contained in the preliminary
Prospectus which was (i) identified to such Indemnified Holder at or prior to
the earlier of the filing with the Commission or the furnishing to such
Indemnified Holder of the corrected Prospectus and (ii) corrected in the final
Prospectus. The foregoing indemnity agreement is in addition to any liability
which the Company may otherwise have to any Indemnified Holder. Such indemnity
shall remain in full force and effect regardless of any investigation made by or
on behalf of the Indemnified Person and shall survive the transfer of the
Registrable Shares by the Purchasers.

Each Holder, severally and not jointly, shall indemnify and hold harmless the
Company, its officers, directors and employees and each person, if any, who
controls the Company within the meaning of the Securities Act, from and against
any loss, claim, damage or liability, joint or several, or any action in respect
thereof, to which the Company or any such officer, employee or controlling
person may become subject, insofar as any such loss, claim, damage or liability
or action arises out of, or is based upon:
any untrue statement or alleged untrue statement of any material fact contained
in the Shelf Registration Statement or Prospectus or any amendment or supplement
thereto or any Blue Sky Application; or
the omission or the alleged omission to state therein 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,

but in each case only to the extent that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with the Holder Questionnaire furnished to the Company by or on
behalf of such Holder (or its related Indemnified Holder) specifically for use
therein, and shall reimburse the Company and any such officer, employee or
controlling person promptly upon demand for any legal or other expenses
reasonably incurred by the Company or any such officer, employee or controlling
person in connection with investigating or defending or preparing to defend
against any such loss, claim, damage, liability or action as such expenses are
incurred.  The foregoing indemnity agreement is in addition to any liability
which any Holder may otherwise have to the Company and any such officer,
employee or controlling person.  The liability of any such Holder under this
Subsection 6(b) shall be limited to the net proceeds received by the Holder from
the sale of the Registrable Shares pursuant to the Shelf Registration Statement.

Promptly after receipt by an indemnified party under this Section 7 of notice of
any claim or the commencement of any action, the indemnified party shall, if a
claim in respect thereof is to be made against the indemnifying party under this
Section 7, notify the indemnifying party in writing of the claim or the
commencement of that action; provided, however, that the failure to notify the
                             --------  -------
indemnifying party shall not relieve it from any liability which it may have
under this Section 7 except to the extent it has been materially prejudiced by
such failure and, provided,
                  --------


                                                                              14

further, that the failure to notify the indemnifying
- -------
party shall not relieve it from any liability which it may have to an
indemnified party otherwise than under this Section 7.  If any such claim or
action shall be brought against an indemnified party, and it shall notify the
indemnifying party thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it wishes, jointly with any other
similarly notified indemnifying party, to assume the defense thereof with
counsel satisfactory to the indemnified party.  After notice from the
indemnifying party to the indemnified party of its election to assume the
defense of such claim or action, the indemnifying party shall not be liable to
the indemnified party under this Section 7 for any legal or other expenses
subsequently incurred by the indemnified party in connection with the defense
thereof other than reasonable costs of investigation; provided, however, that
                                                      --------  -------
the Holders shall have the right to employ a single counsel to represent jointly
the Holders and their officers, employees and controlling persons who may be
subject to liability arising out of any claim in respect of which indemnity may
be sought by the Holders against the Company under this Section 7 if the Holders
seeking indemnification shall have been advised by legal counsel that there may
be one or more legal defenses available to such Holders and their respective
officers, employees and controlling persons that are different from or
additional to those available to the Company, and in that event the fees and
expenses of such separate counsel shall be paid by the Company.  No indemnifying
party shall:
without the prior written consent of the indemnified parties (which consent
shall not be unreasonably withheld) settle or compromise or consent to the entry
of any judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding, or
be liable for any settlement of any such action effected without its written
consent (which consent shall not be unreasonably withheld), but if settled with
its written consent or if there be a final judgment for the plaintiff in any
such action, the indemnifying party agrees to indemnify and hold harmless any
indemnified party from and against any loss of liability by reason of such
settlement or judgment.

If the indemnification provided for in this Section 7 shall for any reason be
unavailable or insufficient to hold harmless an indemnified party under Section
7(a) or 7(b) in respect of any loss, claim, damage or liability (or action in
respect thereof) referred to therein, each indemnifying party shall, in lieu of
indemnifying such indemnified party, contribute to the amount paid or payable by
such indemnified party as a result of such loss, claim, damage or liability (or
action in respect thereof):


                                                                              15

in such proportion as is appropriate to reflect the relative benefits received
by the Company from the offering and sale of the Notes and Warrants on the one
hand and a Holder with respect to the sale by such Holder of the Registrable
Shares on the other, or
if the allocation provided by clause (6)(d)(i) is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative
benefits referred to in clause 6(d)(i) but also the relative fault of the
Company on the one hand and the Holders on the other in connection with the
statements or omissions or alleged statements or alleged omissions that resulted
in such loss, claim, damage or liability (or action in respect thereof), as well
as any other relevant equitable considerations.

The relative benefits received by the Company on the one hand and a Holder on
the other with respect to such offering and such sale shall be deemed to be in
the same proportion as the total net proceeds from the offering of the Notes and
Warrants purchased under the Purchase Agreement (before deducting expenses)
received by the Company, on the one hand, bear to the total proceeds received by
such Holder with respect to its sale of Registrable Shares on the other.  The
relative fault of the parties shall be determined by reference to whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
on the one hand or the Holders on the other, the intent of the parties and their
relative knowledge, access to information and opportunity to correct or prevent
such statement or omission.  The Company and each Holder agree that it would not
be just and equitable if the amount of contribution pursuant to this Section
7(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
first sentence of this paragraph (d).  The amount paid or payable by an
indemnified party as a result of the loss, claim, damage or liability, or action
in respect thereof, referred to above in this Section 7 shall be deemed to
include, for purposes of this Section 7, any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
or preparing to defend any such action or claim.  Notwithstanding the provisions
of this Section 7, no Holder shall be required to contribute any amount in
excess of the net proceeds it received from the sale Registrable Shares pursuant
to the Shelf Registration Statement.  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 Holders' obligations to contribute as
provided in this Section 7(d) are several and not joint.

Underwritten Registrations.  The Holders of Registrable Shares covered by the
Shelf Registration Statement who desire to do so may sell such Registrable
Shares in an Underwritten Offering if approved by the Company in its sole
discretion; provided, however that no such Holder may participate in any
            --------  -------
Underwritten Registration hereunder unless such Holder: agrees to sell such
Holder's Registrable Shares on the basis provided in any underwriting
arrangements approved by the Persons entitled hereunder to approve such
arrangements; and completes and executes all reasonable questionnaires, powers
of attorney, indemnities, underwriting agreements, lock-up letters and other
documents required under the terms of such underwriting arrangements.

In any such Underwritten Offering, the investment banker or investment bankers
and manager or managers that will administer the offering will be selected by a
Majority of Holders whose Registrable Shares are included in such offering;
provided, that such investment bankers and managers must be reasonably
satisfactory to the Company. If requested by the underwriter(s), if any, the
Company agrees to make appropriate officers of the Company available to the
underwriters for meetings with prospective purchasers of the Registrable Shares
and prepare and present to potential investors customary "road


                                                                              16

show" or marketing materials in a manner consistent with other new issuances of
other securities similar to the Registrable Shares.

Miscellaneous.

Actions Affecting Registrable Shares.  The Company shall not, directly or
indirectly, take any action with respect to the Registrable Shares as a class
that would adversely affect the ability of the Holders of Registrable Shares to
include such Registrable Shares in a registration undertaken pursuant to this
Agreement.

No Inconsistent Agreements.  The Company will not, on or after the date of this
Agreement, enter into any agreement with respect to its securities that is
inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof.  In addition, the Company shall
not grant to any of its security holders (other than the Holders of Registrable
Shares in such capacity) the right to include any of its securities in the Shelf
Registration Statement provided for in this Agreement other than the Registrable
Shares.  The Company has not previously entered into any agreement (which has
not expired or been terminated) granting any registration rights with respect to
its securities to any Person which rights conflict with the provisions hereof.

Amendments and Waivers.  This Agreement may not be amended, modified or
supplemented, and waivers or consents to or departures from the provisions
hereof may not be given, unless the Company has obtained the written consent of
a Majority of Holders.

Notices.  Any notices, consents, waivers or other communications required or
permitted to be given under the terms of this Agreement must be in writing and
will be deemed to have been delivered: (i) upon receipt, when delivered
personally; (ii) upon receipt, when sent by facsimile, provided that such notice
is also delivered via regular mail; or (iii) 1 Business Day after deposit with a
nationally recognized overnight delivery service, in each case properly
addressed to the party to receive the same.  The addresses and facsimile numbers
for such communications shall be:

Successors and Assigns.  This Agreement shall inure to the benefit of and be
binding upon the successors and assigns of each of the parties, including
without limitation and without the need for an express assignment, subsequent
Holders of Registrable Shares; provided, however, that (i) this Agreement shall
                               --------  -------
not inure to the benefit of or be binding upon a successor or assign of a Holder
unless and to the extent such successor or assign acquired Registrable Shares
from such Holder and (ii) nothing contained herein shall be deemed to permit any
assignment, transfer or other disposition of Registrable Shares in violation of
the terms of the Purchase Agreement, the Notes or the Warrants.  If any
transferee of any Holder shall acquire Registrable Shares, in any manner,
whether by operation of law or otherwise, such Registrable Shares shall be held

Securities Held by the Company or Their Affiliates. Whenever the consent or
approval of Holders of a specified percentage of Registrable Shares is required
hereunder, Registrable Shares held by the Company or its "affiliates" (as such
term is defined in Rule 405 under the Securities


                                                                              18

Act) shall not be counted in determining whether such consent or approval was
given by the Holders of such required percentage.

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

Governing Law.  This Agreement shall be governed by, and construed in accordance
with, the law of the State of New York.

Severability.  If any one or more of the provisions contained herein, or the
application thereof in any circumstance, is held invalid, illegal or
unenforceable, the validity, legality and enforceability of any such provision
in every other respect and of the remaining provisions contained herein shall
not be affected or impaired thereby.

Entire Agreement. This Agreement is intended by the parties as a final
expression of their agreement and intended to be a complete and exclusive
statement of the agreement and understanding of the parties hereto in respect of
the subject matter contained herein. There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein
with respect to the registration rights granted by the Company with respect to
the Registrable Shares. This Agreement supersedes all prior agreements and
understandings between the parties with respect to such subject matter.

Remedies.  The remedies provided in this Agreement shall be cumulative and in
addition to all other remedies available under this Agreement, the Notes, the
Securities Purchase Agreement,  and the Warrants, at law or in equity (including
a decree of specific performance and/or other injunctive relief), and nothing
herein shall limit the Holder's right to pursue actual damages for any failure
by the Company to comply with the terms of this Agreement.  Amounts set forth or
provided for herein with respect to payments, conversion and the like (and the
computation thereof) shall be the amounts to be received by the Holder and shall
not, except as expressly provided herein, be subject to any other obligation of
the Company (or the performance thereof).  The Company acknowledges that a
breach by it of its obligations hereunder will cause irreparable harm to the
Holder and that the remedy at law for any such breach may be inadequate.  The
Company therefore agrees that, in the event of any such breach or threatened
breach, the Holder shall be entitled, in addition to all other available
remedies, to an injunction restraining any breach, without the necessity of
showing economic loss and without any bond or other security being required.


                                                                              19

In Witness Whereof, the parties have executed this Agreement as of the date
first written above.

             FORM OF SELLING SECURITYHOLDER NOTICE AND QUESTIONNAIRE

     The undersigned beneficial holder of shares of common stock, no par value
per share (the "Common Stock"), of Genus, Inc. ("Genus" or "Registrant"), issued
or issuable upon conversion of Genus' 7% Convertible Subordinated Notes due 2005
(the "Notes") or exercise of warrants to purchase Common Stock, (collectively
such shares are the "Registrable Shares") understands that the Registrant has
filed or intends to file with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (the "Shelf Registration
Statement") for the registration and resale under Rule 415 of the Securities Act
of 1933, as amended (the "Securities Act" ), of the Registrable Shares, in
accordance with the terms of the Registration Rights Agreement, dated as of
August 14, 2002 (the "Registration Rights Agreement"), between Genus and the
purchasers named therein.  A copy of the Registration Rights Agreement is
available from Genus upon request at the address set forth below.
Each capitalized term not otherwise defined herein shall have the meaning
ascribed thereto in the Registration Rights Agreement.  Each beneficial owner of
Registrable Shares is entitled to the benefits of the Registration Rights
Agreement.  In order to sell or otherwise dispose of any Registrable Shares
pursuant to the Shelf Registration Statement, a beneficial owner of Registrable
Shares generally will be required to be named as a selling securityholder in the
related prospectus, deliver a prospectus to purchasers of Registrable Shares and
be bound by those provisions of the Registration Rights Agreement applicable to
such beneficial owner (including certain indemnification provisions, as
described below).  Beneficial owners that do not complete this Notice and
Questionnaire and deliver it to Genus within 10 Business Days of the date of
this Notice and Questionnaire as provided below will not be named as selling
securityholders in the prospectus and therefore will not be permitted to sell
any Registrable Shares pursuant to the Shelf Registration Statement.
Notwithstanding the foregoing, transferees of all or any portion of the
Registrable Shares may complete this Notice and Questionnaire and deliver it to
Genus on or prior to the 20th business day after the date of completion of the
transfer to such transferee.  Beneficial owners are encouraged to complete and
deliver this Notice and Questionnaire prior to the effectiveness of the Shelf
Registration Statement so that such beneficial owners may be named as selling
securityholders in the related prospectus at the time of effectiveness.
BENEFICIAL OWNERS THAT DO NOT COMPLETE THIS NOTICE AND QUESTIONNAIRE AND TIMELY
DELIVER IT TO GENUS SHALL NOT BE NAMED AS SELLING SECURITYHOLDERS IN THE
PROSPECTUS INCLUDED IN THE SHELF REGISTRATION STATEMENT AND THEREFORE SHALL NOT
BE PERMITTED TO SELL ANY REGISTRABLE SHARES PURSUANT TO THE SHELF REGISTRATION
STATEMENT.  Genus has agreed to pay liquidated damages pursuant to the
Registration Rights Agreement under certain circumstances as set forth therein.

     Certain legal consequences arise from being named as a selling
securityholder in the Shelf Registration Statement and the related prospectus.
Accordingly, holders and beneficial owners of Registrable Shares are advised to
consult their own securities law



counsel regarding the consequences of being named or not being named as a
selling securityholder in the Shelf Registration Statement and the related
prospectus.
