2.             Registration.


 


a.             Mandatory Registration.  The Company shall prepare, and, as soon as practicable but in no
event later than 30 days after the Closing Date (as defined in the Securities
Purchase Agreement) (the “Filing Deadline”), file with the SEC a
Registration Statement on Form S-3 covering the resale of all of the
Registrable Securities.  In the event
that Form S-3 is unavailable for such a registration, the Company shall use
such other form as is available for such a registration, subject to the
provisions of Section 2(d).  The
Registration Statement prepared pursuant hereto shall register for resale at
least that number of shares of Common Stock equal to the product of (x) 1.3 and
(y) the number of Registrable Securities as of the trading day immediately
preceding the date the Registration Statement is initially filed with the SEC,
subject to adjustment as provided in Section 2(e).  The Company shall use its best efforts to have the Registration
Statement declared effective by the SEC as soon as practicable, but in no event
later than the date which is (i) in the event that the Registration Statement
is not subject to a full review by the SEC, 90 days after the Closing Date or
(ii) in the event that the Registration Statement is subject to a full
review  by the SEC, 120 days after the
Closing Date (the “Effectiveness Deadline”).


 


2

















 


b.             Allocation of Registrable Securities.  The initial number of Registrable Securities
included in any Registration Statement and each increase in the number of
Registrable Securities included therein shall be allocated pro rata among the
Investors based on the number of Registrable Securities held by each Investor
at the time the Registration Statement covering such initial number of
Registrable Securities or increase thereof is declared effective by the SEC.  In the event that an Investor sells or
otherwise transfers any of such Investor’s Registrable Securities, each
transferee shall be allocated a pro rata portion of the then remaining number
of Registrable Securities included in such Registration Statement for such
transferor.  Any shares of Common Stock
included in a Registration Statement and which remain allocated to any Person
which ceases to hold any Registrable Securities covered by such Registration
Statement shall be allocated to the remaining Investors, pro rata based on the
number of Registrable Securities then held by such Investors which are covered
by such Registration Statement.  In no
event shall the Company include any securities other than Registrable Securities
on any Registration Statement without the prior written consent of Buyers
holding at least a majority of the Registrable Securities.


 


c.             Legal Counsel. 
Subject to Section 5 hereof, the Buyers holding at least a majority of
the Registrable Securities shall have the right to select one legal counsel to
review and oversee any registration pursuant to this Section 2 (“Legal
Counsel”), which shall be Schulte Roth & Zabel LLP or such other
counsel as thereafter designated by the holders of at least a majority of the
Registrable Securities.  The Company and
Legal Counsel shall reasonably cooperate with each other in performing the
Company’s obligations under this Agreement.


 


d.             Ineligibility for Form S-3.  In the event that Form S-3 is not available
for the registration of the resale of Registrable Securities hereunder, the
Company shall (i) register the resale of the Registrable Securities on another
appropriate form reasonably acceptable to the holders of at least a majority of
the Registrable Securities and (ii) undertake to register the Registrable
Securities on Form S-3 as soon as such form is available, provided that the
Company shall maintain the effectiveness of the Registration Statement then in
effect until such time as a Registration Statement on Form S-3 covering the
Registrable Securities has been declared effective by the SEC.


 


e.             Sufficient Number of Shares Registered.  In the event the number of shares available
under a Registration Statement filed pursuant to Section 2(a) is insufficient
to cover all of the Registrable Securities required to be covered by such
Registration Statement or an Investor’s allocated portion of the Registrable
Securities pursuant to Section 2(b), the Company shall amend the applicable
Registration Statement, or file a new Registration Statement (on the short form
available therefor, if applicable), or both, so as to cover at least 130% of
the number of such Registrable Securities 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 fifteen (15) days after the Company becomes aware of the necessity
therefor.  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.  For purposes of the foregoing provision, the
number of shares available under a Registration Statement shall be deemed
“insufficient to cover all of the Registrable Securities” if at any time the
number of shares of Common Stock available for resale under such Registration


 


3

















 


Statement is less than
the product of (i) the number of Registrable Securities issued or issuable upon
conversion of the Notes and upon exercise of the Warrants, if any, covered by
such Registration Statement and (ii) 1.1. 
The calculation set forth in the foregoing sentence shall be made
without regard to any limitations on the conversion of the Notes or the
exercise of the Warrants and such calculation shall assume that the Notes and
the Warrants are then convertible into shares of Common Stock and the maximum
number of Interest Shares under the Notes, assuming the applicable portions of
the initial outstanding principal amount of the Notes remains outstanding
through the applicable scheduled maturity dates and assuming no conversions or
redemptions of the Notes prior to the scheduled maturity date, are issuable at
the then prevailing Interest Conversion Price (as defined in the Notes), Conversion
Rate (as defined in the Notes) or Warrant Exercise Price (as defined in the
Warrants), as applicable.


 


f.              Effect of Failure to File and Obtain and Maintain
Effectiveness of Registration Statement. 
If (i) a Registration Statement covering all the Registrable Securities
required to be covered thereby and required to be filed by the Company pursuant
to this Agreement is (A) not filed with the SEC on or before the Filing
Deadline (a “Filing Failure”) or (B) not declared effective by the SEC on
or before the Effectiveness Deadline (an “Effectiveness Failure”) or (ii) on any day
after such Registration Statement has been declared effective by the SEC sales
of all the Registrable Securities required to be included on such Registration
Statement cannot be made (other than during an Allowable Grace Period (as
defined in Section 3(r)) pursuant to such Registration Statement (including,
without limitation, because of a failure to keep such Registration Statement
effective, to disclose such information as is necessary for sales to be made
pursuant to such Registration Statement or to register sufficient shares of
Common Stock)(a “Maintenance Failure”), then, as partial relief for the
damages to any holder by reason of any such delay in or reduction of its
ability to sell the underlying shares of Common Stock (which remedy shall not
be exclusive of any other remedies available at law or in equity), the Company
shall pay to each holder of Notes relating to such Registration Statement: (I)
on each of the day of a Filing Failure, an Effectiveness Failure and the
initial day of a Maintenance Failure, an amount in cash equal to the product of
(i) the aggregate Principal (as such term is defined in the Notes) of such
Investor’s Notes convertible into Conversion Shares included in such
Registration Statement multiplied by (ii) 0.01, and (II) on the earlier of last
day of each 30 day period after a Filing Failure, an Effectiveness Failure and
the initial day of a Maintenance Failure, as the case may be, or on the third
Business Day after any such Filing Failure, Effectiveness Failure or
Maintenance Failure is cured, an amount in cash equal to the product of (i) the
aggregate Principal of such Investor’s Notes convertible into Conversion Shares
included in such Registration Statement multiplied by (ii) 0.02.  In the event the Company fails to make any
payments pursuant to this Section 2(f) in a timely manner, such payments shall
bear interest at the rate of 1.5% per month (prorated for partial months) until
paid in full.


 


3.             Related Obligations.


 


At such time as the
Company is obligated to file a Registration Statement with the SEC pursuant to
Section 2(a), 2(d) or 2(e), the Company will use its best efforts to effect the
registration of the Registrable Securities in accordance with the intended
method of disposition thereof and, pursuant thereto, the Company shall have the
following obligations:


 


4

















 


a.             The Company shall submit to the SEC, within two (2)
Business Days after the Company learns that no review of a particular
Registration Statement will be made by the staff of the SEC or that the staff
of the SEC has no further comments on a particular Registration Statement, as
the case may be, a request for acceleration of effectiveness of such
Registration Statement to a time and date not later than 48 hours after the
submission of such request.  The Company
shall keep each Registration Statement effective pursuant to Rule 415 at all
times until the earlier of (i) the date as of which the Investors may sell all
of the Registrable Securities covered by such Registration Statement without
restriction pursuant to Rule 144(k) (or successor thereto) promulgated under
the 1933 Act or (ii) the date on which the Investors shall have sold all the Registrable
Securities covered by such Registration Statement (the “Registration Period”).  The Company shall ensure that each
Registration Statement (including any amendments or supplements thereto and
prospectuses contained therein) shall not contain any 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 the case of prospectuses, in
the light of the circumstances in which they were made) not misleading.


 


b.             The Company shall prepare and file with the SEC such
amendments (including post-effective amendments) and supplements to a
Registration Statement and the prospectus used in connection with such
Registration Statement, which prospectus is to be filed pursuant to Rule 424
promulgated under the 1933 Act, as may be necessary to keep such Registration
Statement effective at all times during the Registration Period, and, during
such period, comply with the provisions of the 1933 Act with respect to the
disposition of all Registrable Securities of the Company covered by such
Registration Statement until such time as all of such Registrable Securities
shall have been disposed of in accordance with the intended methods of
disposition by the seller or sellers thereof as set forth in such Registration
Statement.  In the case of amendments
and supplements to a Registration Statement which are required to be filed
pursuant to this Agreement (including pursuant to this Section 3(b)) by reason
of the Company filing a report on Form 10-K, Form 10-Q or Form 8-K or any
analogous report under the Securities Exchange Act of 1934, as amended (the “1934 Act”),
the Company shall have incorporated such report by reference into such
Registration Statement, if applicable, or shall file such amendments or
supplements with the SEC on the same day on which the 1934 Act report is filed
which created the requirement for the Company to amend or supplement such
Registration Statement.


 


c.             The Company shall (A) permit Legal Counsel to review and
comment upon (i) a Registration Statement at least five (5) Business Days prior
to its filing with the SEC and (ii) all amendments and supplements to all
Registration Statements (except for Annual Reports on Form 10-K, Quarterly
Reports on Form 10-Q and Current Reports on Form 8-K and any similar or
successor reports) within a reasonable number of days prior to their filing
with the SEC, and (B) not file any Registration Statement or amendment or
supplement thereto in a form to which Legal Counsel reasonably objects.  The Company shall not submit a request for
acceleration of the effectiveness of a 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) copies
of any correspondence from the SEC or the staff of the SEC to the Company or
its representatives relating to any Registration Statement, (ii) promptly after
the same is prepared


 


5

















 


and filed with the SEC,
one copy of any Registration Statement and any amendment(s) thereto, including
financial statements and schedules, all documents incorporated therein by
reference, if requested by an Investor and not otherwise available on the EDGAR
system, and all exhibits and (iii) upon the effectiveness of any Registration
Statement, one copy of the prospectus included in such Registration Statement
and all amendments and supplements thereto. 
The Company shall reasonably cooperate with Legal Counsel in performing
the Company’s obligations pursuant to this Section 3.


 


d.             The Company shall furnish to each Investor whose
Registrable Securities are included in any Registration Statement, without
charge,  (i) promptly after the same is
prepared and filed with the SEC, at least one copy of such Registration
Statement and any amendment(s) thereto, including financial statements and
schedules, all documents incorporated therein by reference, if requested by an
Investor and not otherwise available on the EDGAR system, all exhibits and each
preliminary prospectus, (ii) upon the effectiveness of any Registration
Statement, ten (10) copies of the prospectus included in such Registration
Statement and all amendments and supplements thereto (or such other number of
copies as such Investor may reasonably request) and (iii) such other documents,
including copies of any preliminary or final prospectus, as such Investor may
reasonably request from time to time in order to facilitate the disposition of
the Registrable Securities owned by such Investor.


 


e.             The Company shall use its best efforts to (i) register
and qualify, unless an exemption from registration and qualification applies,
the resale by Investors of the Registrable Securities covered by a Registration
Statement under such other securities or “blue sky” laws of all applicable
jurisdictions in the United States, (ii) prepare and file in those
jurisdictions such amendments (including post-effective amendments) and supplements
to such registrations and qualifications as may be necessary to maintain the
effectiveness thereof during the Registration Period, (iii) take such other
actions as may be necessary to maintain such registrations and qualifications
in effect at all times during the Registration Period, and (iv) take all other
actions reasonably necessary or advisable to qualify the Registrable Securities
for sale in such jurisdictions; provided, however, that the Company shall not
be required in connection therewith or as a condition thereto to (x) qualify to
do business in any jurisdiction where it would not otherwise be required to
qualify but for this Section 3(e), (y) subject itself to general taxation in
any such jurisdiction, or (z) file a general consent to service of process in
any such jurisdiction.  The Company
shall promptly notify Legal Counsel and each Investor who holds Registrable
Securities of the receipt by the Company of any notification with respect to
the suspension of the registration or qualification of any of the Registrable
Securities for sale under the securities or “blue sky” laws of any jurisdiction
in the United States or its receipt of actual notice of the initiation or
threatening of any proceeding for such purpose.


 


f.              The Company shall notify Legal Counsel and each
Investor in writing of the happening of any event, as promptly as practicable
after becoming aware of such event, as a result of which the prospectus
included in a Registration Statement, as then in effect, includes an untrue statement
of a material fact or omission 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 (provided that in no
event shall such notice contain any material, nonpublic information), and,
subject to Section 3(r), promptly prepare a supplement or


 


6

















 


amendment to such
Registration Statement to correct such untrue statement or omission, and deliver
ten (10) copies of such supplement or amendment to Legal Counsel and each
Investor (or such other number of copies as Legal Counsel or such Investor may
reasonably request).  The Company shall
also promptly notify Legal Counsel and each Investor in writing (i) when a
prospectus or any prospectus supplement or post-effective amendment has been
filed, and when a Registration Statement or any post-effective amendment has
become effective (notification of such effectiveness shall be delivered to
Legal Counsel and each Investor by facsimile on the same day of such
effectiveness and by overnight mail), (ii) of any request by the SEC for
amendments or supplements to a Registration Statement or related prospectus or
related information, and (iii) of the Company’s reasonable determination that a
post-effective amendment to a Registration Statement would be appropriate.


 


g.             The Company shall use its best efforts to prevent the
issuance of any stop order or other suspension of effectiveness of a
Registration Statement, or the suspension of the qualification of any of the
Registrable Securities for sale in any jurisdiction and, if such an order or
suspension is issued, to obtain the withdrawal of such order or suspension at
the earliest possible moment and to notify Legal Counsel and each Investor who
holds Registrable Securities being sold of the issuance of such order and the
resolution thereof or its receipt of actual notice of the initiation or threat
of any proceeding for such purpose.


 


h.             If any Investor is required under applicable securities
law to be described in the Registration Statement as an underwriter, at the
reasonable request of such Investor, the Company shall furnish to such
Investor, on the date of the effectiveness of the Registration Statement and
thereafter from time to time on such dates as an Investor may reasonably
request (i) a letter, dated such date, from the Company’s independent certified
public accountants in form and substance as is customarily given by independent
certified public accountants to underwriters in an underwritten public
offering, addressed to the Investors, and (ii) an opinion, dated as of such
date, of counsel representing the Company for purposes of such Registration
Statement, in form, scope and substance as is customarily given in an
underwritten public offering, addressed to the Investors.


 


i.              Notwithstanding the provisions of Section 4(i) of the
Securities Purchase Agreement, upon the written request of any Investor in
connection with any Investor’s due diligence requirements, if any, the Company
shall make available for inspection by (i) any Investor, (ii) Legal Counsel and
(iii) one firm of accountants or other agents retained by the Investors
(collectively, the “Inspectors”), all pertinent financial and
other records, and pertinent corporate documents and properties of the Company
(collectively, the “Records”), as shall be reasonably deemed
necessary by each Inspector, and cause the Company’s officers, directors and
employees to supply all information which any Inspector may reasonably request;
provided, however, that each Inspector shall agree in writing to hold in strict
confidence and shall not make any disclosure (except to an Investor) or use of
any Record or other information which the Company determines in good faith to
be confidential, and of which determination the Inspectors are so notified,
unless (a) the disclosure of such Records is necessary to avoid or correct a
misstatement or omission in any Registration Statement or is otherwise required
under the 1933 Act, (b) the release of such Records is ordered pursuant to a
final, non-appealable subpoena or order from a court or government body of
competent jurisdiction, or (c) the information in such


 


7

















 


Records has been made
generally available to the public other than by disclosure in violation of this
or any other agreement of which the Inspector has knowledge.  Each Investor agrees that it shall, upon
learning that disclosure of such Records is required or is sought in or by a
court or governmental body of competent jurisdiction or through other means,
give prompt notice to the Company and allow the Company, at its expense, to
undertake appropriate action to prevent disclosure of, or to obtain a
protective order for, the Records deemed confidential.  Nothing herein (or in any other
confidentiality agreement between the Company and any Investor) shall be deemed
to limit the Investors’ ability to sell Registrable Securities in a manner
which is otherwise consistent with applicable laws and regulations.


 


j.              The Company shall hold in confidence and not make any
disclosure of information concerning an Investor provided to the Company unless
(i) disclosure of such information is necessary to comply with federal or state
securities laws, (ii) the disclosure of such information is necessary to avoid
or correct a misstatement or omission in any Registration Statement, (iii) the
release of such information is ordered pursuant to a subpoena or other final,
non-appealable order from a court or governmental body of competent
jurisdiction, or (iv) such information has been made generally available to the
public other than by disclosure in violation of this Agreement or any other
agreement.  The Company agrees that it
shall, upon learning that disclosure of such information concerning an Investor
is sought in or by a court or governmental body of competent jurisdiction or
through other means, give prompt written notice to such Investor and allow such
Investor, at the Investor’s expense, to undertake appropriate action to prevent
disclosure of, or to obtain a protective order for, such information.


 


k.             The Company shall use its best efforts either to (i)
cause all the Registrable Securities covered by a Registration Statement to be
listed on each securities exchange on which securities of the same class or
series issued by the Company are then listed, if any, if the listing of such
Registrable Securities is then permitted under the rules of such exchange, or
(ii) secure designation and quotation of all the Registrable Securities covered
by a Registration Statement on the 
NASDAQ National Market, or (iii) if, despite the Company’s best efforts
to satisfy the preceding clause (i) or (ii), the Company is unsuccessful in
satisfying the preceding clause (i) or (ii), to secure the inclusion for
quotation on The  NASDAQ SmallCap Market
for such Registrable Securities and, without limiting the generality of the
foregoing, to use its best efforts to arrange for at least two market makers to
register with the National Association of Securities Dealers, Inc. (“NASD”)
as such with respect to such Registrable Securities.  The Company shall pay all fees and expenses in connection with
satisfying its obligation under this Section 3(k).


 


l.              The Company shall cooperate with the Investors who hold
Registrable Securities being offered and, to the extent applicable, facilitate
the timely preparation and delivery of certificates (not bearing any
restrictive legend) representing the Registrable Securities to be offered
pursuant to a Registration Statement and enable such certificates to be in such
denominations or amounts, as the case may be, as the Investors may reasonably
request and registered in such names as the Investors may request.


 


m.            If requested by an Investor, the Company shall (i) as
soon as practicable incorporate in a prospectus supplement or post-effective
amendment such


 


8

















 


information as an
Investor reasonably requests to be included therein relating to the sale and
distribution of Registrable Securities, including, without limitation,
information with respect to the number of Registrable Securities being offered
or sold, the purchase price being paid therefor and any other terms of the
offering of the Registrable Securities to be sold in such offering; (ii) as
soon as practicable make all required filings of such prospectus supplement or
post-effective amendment after being notified of the matters to be incorporated
in such prospectus supplement or post-effective amendment; and (iii) as soon as
practicable, supplement or make amendments to any Registration Statement if
reasonably requested by an Investor holding any Registrable Securities.


 


n.             The Company shall use its best efforts to cause the Registrable
Securities covered by a Registration Statement to be registered with or
approved by such other governmental agencies or authorities as may be necessary
to consummate the disposition of such Registrable Securities.


 


o.             The Company shall make generally available to its
security holders as soon as practical, but not later than ninety (90) days
after the close of the period covered thereby, an earnings statement (in form
complying with, and in the manner provided by, the provisions of Rule 158 under
the 1933 Act) covering a twelve-month period beginning not later than the first
day of the Company’s fiscal quarter next following the effective date of a
Registration Statement.


 


p.             The Company shall otherwise use its best efforts to
comply with all applicable rules and regulations of the SEC in connection with
any registration hereunder.


 


q.             Within two (2) Business Days after a Registration
Statement which covers Registrable Securities is ordered effective by the SEC,
the Company shall deliver, and shall cause legal counsel for the Company to
deliver, to the transfer agent for such Registrable Securities (with copies to
the Investors whose Registrable Securities are included in such Registration
Statement) confirmation that such Registration Statement has been declared
effective by the SEC in the form attached hereto as Exhibit A.


 


r.              Notwithstanding anything to the contrary herein, at any
time after the Registration Statement has been declared effective by the SEC,
the Company may delay the disclosure of material non-public information
concerning the Company the disclosure of which at the time is not, in the good
faith opinion of the Board of Directors of the Company and its counsel, in the
best interest of the Company and, in the opinion of counsel to the Company,
otherwise required (a “Grace Period”); provided, that the Company
shall promptly (i) notify the Investors in writing of the existence of a Grace
Period in conformity with the provisions of this Section 3(r)(provided that in
each notice the Company will not disclose the content of such material
non-public information to the Investors) and the date on which the Grace Period
will begin, and (ii) notify the Investors in writing of the date on which the
Grace Period ends; and, provided further, that no Grace Period shall exceed ten
(10) consecutive days and during any three hundred sixty five (365) day period
such Grace Periods shall not exceed an aggregate of thirty (30) days and the
first day of any Grace Period must be at least two (2) trading days after the
last day of any prior Grace Period (each, an “Allowable Grace Period”).  For purposes of


 


9

















 


determining the length of
a Grace Period above, the Grace Period shall begin on and include the date the
Investors receive the notice referred to in clause (i) and shall end on and
include the later of the date the Investors receive the notice referred to in
clause (ii) and the date referred to in such notice.  The provisions of Section 3(g) hereof shall not be applicable
during the period of any Allowable Grace Period.  Upon expiration of the Grace Period, the Company shall again be
bound by the first sentence of Section 3(f) with respect to the information
giving rise thereto unless such material non-public information is no longer
applicable.  Notwithstanding anything to
the contrary, the Company shall cause its transfer agent to deliver unlegended
shares of Common Stock to a transferee of an Investor in accordance with the
terms of the Securities Purchase Agreement in connection with any sale of
Registrable Securities with respect to which an Investor has entered into a
contract for sale, and delivered a copy of the prospectus included as part of
the applicable Registration Statement, prior to the Investor’s receipt of the
notice of a Grace Period and for which the Investor has not yet settled.


 


4.             Obligations Of The Investors.


 


a.             At least seven (7) Business Days prior to the first
anticipated filing date of a Registration Statement, the Company shall notify
each Investor in writing of the information the Company requires from each such
Investor if such Investor elects to have any of such Investor’s Registrable
Securities included in such Registration Statement.  It shall be a condition precedent to the obligations of the
Company to complete the registration pursuant to this Agreement with respect to
the Registrable Securities of a particular Investor that such Investor shall
furnish to the Company such information regarding itself, the Registrable
Securities held by it and the intended method of disposition of the Registrable
Securities held by it as shall be reasonably required to effect the
effectiveness of the registration of such Registrable Securities and shall
execute such documents in connection with such registration as the Company may
reasonably request.


 


b.             Each Investor, by such Investor’s acceptance of the
Registrable Securities, agrees to cooperate with the Company as reasonably
requested by the Company in connection with the preparation and filing of any
Registration Statement hereunder, unless such Investor has notified the Company
in writing of such Investor’s election to exclude all of such Investor’s
Registrable Securities from such Registration Statement.


 


c.             Each Investor agrees that, upon receipt of any notice
from the Company of the happening of any event of the kind described in Section
3(g) or the first sentence of 3(f), such Investor will immediately discontinue
disposition of Registrable Securities pursuant to any Registration Statement(s)
covering such Registrable Securities until such Investor’s receipt of the
copies of the supplemented or amended prospectus contemplated by Section 3(g)
or the first sentence of 3(f) or receipt of notice that no supplement or
amendment is required.  Notwithstanding
anything to the contrary, the Company shall cause its transfer agent to deliver
unlegended shares of Common Stock to a transferee of an Investor in accordance
with the terms of the Securities Purchase Agreement in connection with any sale
of Registrable Securities with respect to which an Investor has entered into a
contract for sale prior to the Investor’s receipt of a notice from the Company
of the happening of any event of the kind described in Section 3(g) or the
first sentence of 3(f) and for which the Investor has not yet settled.


 


10

















 


d.             Each Investor covenants and agrees that it will comply
with the prospectus delivery requirements of the 1933 Act as applicable to it
in connection with sales of Registrable Securities pursuant to a Registration
Statement.


 


5.             Expenses of Registration.


 


All reasonable expenses,
other than underwriting discounts and commissions, incurred in connection with
registrations, filings or qualifications pursuant to Sections 2 and 3,
including, without limitation, all registration, listing and qualifications
fees, printers and accounting fees, and fees and disbursements of counsel for
the Company shall be paid by the Company. 
All underwriting discounts and selling commissions applicable to the
sale of the Registrable Securities shall be paid by the Investors, provided,
however, that the Company shall reimburse the Investors for the fees and
disbursements of Legal Counsel in connection with registration, filing or
qualification pursuant to Sections 2 and 3 of this Agreement, which amount
shall be limited to $5,000.


 


6.             Indemnification.


 


In the event any
Registrable Securities are included in a Registration Statement under this
Agreement:


 


a.             To the fullest extent permitted by law, the Company
will, and hereby does, indemnify, hold harmless and defend each Investor, the
directors, officers, partners, employees, agents, representatives of, and each
Person, if any, who controls any Investor within the meaning of the 1933 Act or
the 1934 Act (each, an “Indemnified Person”), against any losses,
claims, damages, liabilities, judgments, fines, penalties, charges, costs,
reasonable attorneys’ fees, amounts paid in settlement or expenses, joint or
several (collectively, “Claims”), incurred in investigating,
preparing or defending any action, claim, suit, inquiry, proceeding,
investigation or appeal taken from the foregoing by or before any court or
governmental, administrative or other regulatory agency, body or the SEC,
whether pending or threatened, whether or not an indemnified party is or may be
a party thereto (“Indemnified Damages”), to which any of them
may become subject insofar as such Claims (or actions or proceedings, whether
commenced or threatened, in respect thereof) arise out of or are based
upon:  (i) any untrue statement or
alleged untrue statement of a material fact in a Registration Statement or any
post-effective amendment thereto or in any filing made in connection with the
qualification of the offering under the securities or other “blue sky” laws of
any jurisdiction in which Registrable Securities are offered (“Blue Sky
Filing”), or the omission or alleged omission to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading, (ii) any untrue statement or alleged untrue statement of a
material fact contained in any preliminary prospectus if used prior to the
effective date of such Registration Statement, or contained in the final
prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement thereto with the SEC) or the omission or alleged omission
to state therein any material fact necessary to make the statements made
therein, in the light of the circumstances under which the statements therein
were made, not misleading, (iii) any violation or alleged violation by the
Company of the 1933 Act, the 1934 Act, any other law, including, without
limitation, any state securities law, or any rule or regulation thereunder
relating to the offer or


 


11

















 


sale of the Registrable
Securities pursuant to a Registration Statement or (iv) any material violation
of this Agreement (the matters in the foregoing clauses (i) through (iv) being,
collectively, “Violations”).  Subject
to Section 6(c), the Company shall reimburse the Indemnified Persons, promptly
as such expenses are incurred and are due and payable, for any legal fees or
other reasonable expenses incurred by them in connection with investigating or
defending any such Claim. 
Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 6(a):  (i) shall not apply to a Claim by an
Indemnified Person arising out of or based upon a Violation which occurs in
reliance upon and in conformity with information furnished in writing to the
Company by such Indemnified Person for such Indemnified Person expressly for
use in connection with the preparation of the Registration Statement or any
such amendment thereof or supplement thereto, if such prospectus was timely
made available by the Company pursuant to Section 3(d); (ii) with respect to
any preliminary prospectus, shall not inure to the benefit of any such Person
from whom the Person asserting any such Claim purchased the Registrable
Securities that are the subject thereof (or to the benefit of any Person
controlling such Person) if the untrue statement or omission of material fact
contained in the preliminary prospectus was corrected in the prospectus, as
then amended or supplemented, if such prospectus was timely made available by
the Company pursuant to Section 3(d), and the Indemnified Person was promptly
advised in writing not to use the incorrect prospectus prior to the use giving
rise to a violation and such Indemnified Person, notwithstanding such advice,
used it or failed to deliver the correct prospectus as required by the 1933 Act
and such correct prospectus was timely made available pursuant to Section 3(d);
(iii) shall not be available to the extent such Claim is based on a failure of
the Investor to deliver or to cause to be delivered the prospectus made
available by the Company, including a corrected prospectus, if such prospectus
or corrected prospectus was timely made available by the Company pursuant to
Section 3(d); and (iv) shall not apply to amounts paid in settlement of any
Claim if such settlement is effected without the prior written consent of the
Company, which consent shall not be unreasonably withheld or delayed.  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 Securities
by the Investors pursuant to Section 9.


 


b.             In connection with any Registration Statement in which
an Investor is participating, each such Investor agrees to severally and not
jointly indemnify, hold harmless and defend, to the same extent and in the same
manner as is set forth in Section 6(a), the Company, each of its directors, each
of its officers who signs the Registration Statement and each Person, if any,
who controls the Company within the meaning of the 1933 Act or the 1934 Act
(each, an “Indemnified Party”), against any Claim or Indemnified Damages
to which any of them may become subject, under the 1933 Act, the 1934 Act or
otherwise, insofar as such Claim or Indemnified Damages arise out of or are
based upon any Violation, in each case to the extent, and only to the extent,
that such Violation occurs in reliance upon and in conformity with written
information furnished to the Company by such Investor expressly for use in
connection with such Registration Statement; and, subject to Section 6(c), such
Investor will reimburse any legal or other expenses reasonably incurred by an Indemnified
Party in connection with investigating or defending any such Claim; provided,
however, that the indemnity agreement contained in this Section 6(b) and the
agreement with respect to contribution contained in Section 7 shall not apply
to amounts paid in settlement of any Claim if such settlement is effected
without the prior written consent of such Investor, which consent shall not be
unreasonably withheld or delayed;


 


12

















 


provided, further,
however, that an Investor shall be liable under this Section 6(b) for only that
amount of a Claim or Indemnified Damages as does not exceed the net proceeds to
such Investor as a result of the sale of Registrable Securities pursuant to
such Registration Statement.  Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such Indemnified Party and shall survive the transfer
of the Registrable Securities by the Investors pursuant to Section 9.  Notwithstanding anything to the contrary
contained herein, the indemnification agreement contained in this Section 6(b)
with respect to any preliminary prospectus shall not inure to the benefit of
any Indemnified Party if the untrue statement or omission of material fact contained
in the preliminary prospectus was corrected on a timely basis in the
prospectus, as then amended or supplemented.


 


c.             Promptly after receipt by an Indemnified Person or
Indemnified Party under this Section 6 of notice of the commencement of any
action or proceeding (including any governmental action or proceeding)
involving a Claim, such Indemnified Person or Indemnified Party shall, if a
Claim in respect thereof is to be made against any indemnifying party under
this Section 6, deliver to the indemnifying party a written notice of the
commencement thereof, and the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party so desires, jointly
with any other indemnifying party similarly noticed, to assume control of the
defense thereof with counsel mutually satisfactory to the indemnifying party
and the Indemnified Person or the Indemnified Party, as the case may be;
provided, however, that an Indemnified Person or Indemnified Party shall have
the right to retain its own counsel with the fees and expenses of not more than
one counsel for such Indemnified Person or Indemnified Party to be paid by the
indemnifying party, if, in the reasonable opinion of the Indemnified Person or
the Indemnified Party, as the case may be, the representation by such counsel
of the Indemnified Person or Indemnified Party and the indemnifying party would
be inappropriate due to actual or potential differing interests between such
Indemnified Person or Indemnified Party and any other party represented by such
counsel in such proceeding.  In the case
of an Indemnified Person, legal counsel referred to in the immediately
preceding sentence shall be selected by the Investors holding at least a
majority in interest of the Registrable Securities included in the Registration
Statement to which the Claim relates. 
The Indemnified Party or Indemnified Person shall cooperate fully with
the indemnifying party in connection with any negotiation or defense of any
such action or Claim by the indemnifying party and shall furnish to the
indemnifying party all information reasonably available to the Indemnified
Party or Indemnified Person which relates to such action or Claim.  The indemnifying party shall keep the Indemnified
Party or Indemnified Person fully apprized at all times as to the status of the
defense or any settlement negotiations with respect thereto.  No indemnifying party shall be liable for
any settlement of any action, claim or proceeding effected without its prior
written consent, provided, however, that the indemnifying party shall not
unreasonably withhold, delay or condition its consent.  No indemnifying party shall, without the
prior written consent of the Indemnified Party or Indemnified Person, consent
to entry of any judgment or enter into any settlement or other compromise which
does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such Indemnified Party or Indemnified Person of a release from all
liability in respect to such Claim or litigation.  Following indemnification as provided for hereunder, the
indemnifying party shall be subrogated to all rights of the Indemnified Party
or Indemnified Person with respect to all third parties, firms or corporations
relating to the matter for which indemnification has been made.  The failure to deliver written notice to the



 


13

















 


indemnifying party within
a reasonable time of the commencement of any such action shall not relieve such
indemnifying party of any liability to the Indemnified Person or Indemnified
Party under this Section 6, except to the extent that the indemnifying party is
prejudiced in its ability to defend such action.


 


d.             The indemnification required by this Section 6 shall be
made by periodic payments of the amount thereof during the course of the
investigation or defense, as and when bills are received or Indemnified Damages
are incurred.


 


e.             The indemnity agreements contained herein shall be in
addition to  (i) any cause of action or
similar right of the Indemnified Party or Indemnified Person against the
indemnifying party or others, and (ii) any liabilities the indemnifying party
may be subject to pursuant to the law.


 


7.             Contribution.


 


To the extent any indemnification by an indemnifying party
is prohibited or limited by law, the indemnifying party agrees to make the
maximum contribution with respect to any amounts for which it would otherwise
be liable under Section 6 to the fullest extent permitted by law; provided,
however, that:  (i) no Person involved
in the sale of Registrable Securities which Person is guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the 1933 Act) in
connection with such sale shall be entitled to contribution from any Person
involved in such sale of Registrable Securities who was not guilty of
fraudulent misrepresentation; and (ii) contribution by any seller of
Registrable Securities shall be limited in amount to the net amount of proceeds
received by such seller from the sale of such Registrable Securities pursuant
to such Registration Statement.


 


8.             Reports Under The 1934 Act.


 


With a view to making
available to the Investors the benefits of Rule 144 promulgated under the 1933
Act or any other similar rule or regulation of the SEC 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:


 


a.             make and keep public information available, as those
terms are understood and defined in Rule 144;


 


b.             file with the SEC in a timely manner all reports and
other documents required of the Company under the 1933 Act and the 1934 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 is required for the applicable provisions of Rule 144; and


 


c.             furnish to each Investor so long as such Investor owns
Registrable Securities, promptly upon request, (i) a written statement by the
Company, if true, that it has complied with the reporting requirements of Rule
144, the 1933 Act and the 1934 Act, (ii) a copy


 


14

















 


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.


 


9.             Assignment of Registration Rights.


 


The rights under this
Agreement shall be automatically assignable by the Investors to any transferee
of all or any portion of such Investor’s Registrable Securities if:  (i) 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; (ii)
the Company is, within a reasonable time after such transfer or assignment,
furnished with written notice of (a) the name and address of such transferee or
assignee, and (b) the securities with respect to which such registration rights
are being transferred or assigned; (iii) immediately following such transfer or
assignment the further disposition of such securities by the transferee or
assignee is restricted under the 1933 Act and applicable state securities laws;
(iv) at or before the time the Company receives the written notice contemplated
by clause (ii) of this sentence the transferee or assignee agrees in writing
with the Company to be bound by all of the provisions contained herein; and (v)
such transfer shall have been made in accordance with the applicable
requirements of the Securities Purchase Agreement.


 


10.           Amendment of Registration Rights.


 


Provisions 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
then hold at least a majority of the Registrable Securities.  Any amendment or waiver effected in
accordance with this Section 10 shall be binding upon each Investor and the
Company.  No such amendment shall be
effective to the extent that it applies to less than all of the holders of the
Registrable Securities.  No
consideration shall be offered or paid to any Person to amend or consent to a
waiver or modification of any provision of any of this Agreement unless the
same consideration also is offered to all of the parties to this Agreement.


 


11.           Miscellaneous.


 


a.             A Person is deemed to be a holder of Registrable
Securities whenever such Person owns or is deemed to own of record such
Registrable Securities.  If the Company
receives conflicting instructions, notices or elections from two or more
Persons with respect to the same Registrable Securities, the Company shall act
upon the basis of instructions, notice or election received from the such
record owner of such Registrable Securities.


 


b.             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 confirmation of transmission is mechanically or
electronically generated and kept on file by the sending party); or (iii) one
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:

d.             All questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be governed by the
internal laws of the State of New York, without giving effect to any choice of
law or conflict of law provision or rule (whether of


 


16

















 


the State of New York or
any other jurisdictions) that would cause the application of the laws of any
jurisdictions other than the State of New York.  Each party hereby irrevocably submits to the non- exclusive
jurisdiction of the state and federal courts sitting The City of New York,
Borough of Manhattan, 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,

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 for such 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.  If any provision of
this Agreement shall be invalid or unenforceable in any jurisdiction, such
invalidity or unenforceability shall not affect the validity or enforceability
of the remainder of this Agreement in that jurisdiction or the validity or
enforceability of any provision of this Agreement in any other
jurisdiction.  EACH PARTY HEREBY
IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY
TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION HEREWITH
OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.


 


e.             This Agreement, the other Transaction Documents (as
defined in the Securities Purchase Agreement) and the instruments referenced
herein and therein constitute the entire agreement among the parties hereto
with respect to the subject matter hereof and thereof.  There are no restrictions, promises,
warranties or undertakings, other than those set forth or referred to herein
and therein.  This Agreement, the other
Transaction Documents and the instruments referenced herein and therein
supersede all prior agreements and understandings among the parties hereto with
respect to the subject matter hereof and thereof.


 


f.              Subject to the requirements of Section 9, this
Agreement shall inure to the benefit of and be binding upon the permitted
successors and assigns of each of the parties hereto.


 


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


 


h.             This Agreement may be executed in identical
counterparts, each of which shall be deemed an original but all of which shall
constitute one and the same agreement. 
This Agreement, once executed by a party, may be delivered to the other
party hereto by facsimile transmission of a copy of this Agreement bearing the
signature of the party so delivering this Agreement.


 


i.              Each party shall do and perform, or cause to be done

other party may reasonably request


 


17

















 


in order to carry out the
intent and accomplish the purposes of this Agreement and the consummation of
the transactions contemplated hereby.


 


j.              All consents and other determinations required to be
made by the Investors pursuant to this Agreement shall be made, unless
otherwise specified in this Agreement, by Investors holding at least a majority
of the Registrable Securities, determined as if all of the Notes held by
Investors then outstanding have been converted into Registrable Securities and
all Warrants then outstanding have been exercised for Registrable Securities without
regard to any limitations on conversion of the Notes or on exercises of the
Warrants.


 


k.             The language used in this Agreement will be deemed to be
the language chosen by the parties to express their mutual intent and no rules
of strict construction will be applied against any party.

FORM OF NOTICE OF
EFFECTIVENESS


OF REGISTRATION
STATEMENT


 


[Transfer Agent]


Attn:


 


Re:          SuperGen, Inc.


 


Ladies and Gentlemen:


 


We are counsel to
SuperGen, Inc., a Delaware corporation (the “Company”), and have represented
the Company in connection with that certain Securities Purchase Agreement,
dated as of February 10, 2003 (the “Purchase Agreement”), entered into by and
among the Company and the buyers named therein (collectively, the “Holders”)
pursuant to which the Company issued to the Holders its convertible notes (the
“Notes”), convertible into shares of the Company’s common Stock, par value
$.001 per share (the “Common Stock”) and warrants exercisable for shares of
Company Common Stock (the “Warrants”). 
Pursuant to the Purchase Agreement, the Company also has entered into a
Registration Rights Agreement with the Holders (the “Registration Rights
Agreement”) pursuant to which the Company agreed, among other things, to
register the resale of the Registrable Securities (as defined in the
Registration Rights Agreement), including the shares of Company Common Stock
issuable upon conversion of the Notes, the Interest Shares issued or issuable
under the Notes and the shares of Company Common Stock issuable upon exercise
of the Warrants under the Securities Act of 1933, as amended (the “1933
Act”).  In connection with the Company’s
obligations under the Registration Rights Agreement, on
                           ,
200 , the Company filed a Registration Statement on Form S-3 (File No.
333-                          )
(the “Registration Statement”) with the Securities and Exchange Commission (the
“SEC”) relating to the Registrable Securities which names each of the Holders
as a selling stockholder thereunder.


 


In connection with the
foregoing, we advise you that a member of the SEC’s staff has advised us by
telephone that the SEC has entered an order declaring the Registration
Statement effective under the 1933 Act at [ENTER TIME OF EFFECTIVENESS]
on [ENTER
DATE OF EFFECTIVENESS] and we have no knowledge, after
telephonic inquiry of a member of the SEC’s staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.


 


	
   

  	
  Very truly yours,

  
	
   

  	
   

  
	
   

  	
  [ISSUER’S COUNSEL]

  
	
   

  	
   

  
	
   

  	
  By:
