Company fulfilling their obligations or exercising their rights under the
Transaction Documents, including, without limitation, the Company's issuance of
the Securities and the Purchasers' ownership of the Securities.  The Company has
not adopted a stockholder rights plan or similar arrangement relating to

18

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

 

(g)           Certain Trading Activities.  Other than with respect to the
transactions contemplated herein, since the earlier to occur of (1) the time
that such Purchaser was first contacted by the Company, the Placement Agent or
any other Person regarding the transactions contemplated hereby and (2) the
tenth (10th) day prior to the date of this Agreement, neither the Purchaser nor

Person acting on behalf of or pursuant to any understanding with such Purchaser
or Trading Affiliate, effected or agreed to effect any transactions in the
securities of the Company (including, without limitation, any Short Sales
involving the Company’s securities). Notwithstanding the foregoing, in the case
of a Purchaser and/or Trading Affiliate that is, individually or collectively, a
multi-managed investment vehicle whereby separate portfolio managers manage
separate portions of such Purchaser’s or Trading Affiliate’s assets and the
portfolio managers have no direct knowledge of the investment decisions made by
the portfolio managers managing other portions of such Purchaser’s or Trading
Affiliate’s assets, the representation set forth above shall apply only with
respect to the portion of assets managed by the portfolio manager that have
knowledge about the financing transaction contemplated by this Agreement.  Other
than to other Persons party to this Agreement, such Purchaser has maintained the
confidentiality of all disclosures made to it in connection with this
transaction (including the existence and terms of this transaction).
Notwithstanding the foregoing, no Purchaser makes any representation, warranty
or covenant hereby that it will not engage in Short Sales in the securities of
the Company after the time that the transactions contemplated by this Agreement
are first publicly announced as described in Section 5.7, subject to the
restrictions set forth in Section 5.10.

upon the Company or any Purchaser for any commission, fee or other compensation
pursuant to any agreement, arrangement or understanding entered into by or on
behalf of the Purchaser.
 
(i)           Limited Ownership.  The purchase by such Purchaser of the
Securities issuable to it at the Closing will not result in such Purchaser
(individually or together with other Person with whom such Purchaser has
identified, or will have identified, itself as part of a “group” in a public
filing made with the Commission involving the Company’s securities) acquiring,
or obtaining the right to acquire, in excess of 19.99% of the outstanding shares
of Common Stock or the voting power of the Company on a post transaction basis
that assumes that the Closing shall have occurred. Such Purchaser does not
presently intend to, alone or together with others, make a public filing with
the Commission to disclose that it has (or that it together with such other
Persons have) acquired, or obtained the right to acquire, as a result of the
Closing (when added to any other securities of the Company that it or they then
own or have the right to acquire), in excess of 19.99% of the outstanding shares
of Common Stock or the voting power of the Company on a post transaction basis
that assumes that the Closing shall have occurred.

other materials presented by or on behalf of the Company to the Purchaser in
connection with the purchase of the Securities constitutes legal, tax or
investment advice.  Such Purchaser has consulted such legal, tax and investment

to the Company that no filing is required by the Company with any governmental
authority in such Purchaser’s jurisdiction in connection with the transactions

payment for, and its continued ownership of the Securities, will not violate any
applicable securities or other laws of his, her or its jurisdiction.

ARTICLE IV.
REGISTRATION RIGHTS
 
4.1          Registration; Definitions.
 
(a)           No later than thirty (30) days following the Closing Date (the
“Registration Due Date”), the Company shall prepare and file with the Commission
a registration statement covering the resale of all of the Registrable
Securities (the “Registration Statement”); provided, however, that if the
Registration Due Date falls on a Saturday, Sunday or other day on which the
Commission is not open for business, then the Registration Due Date shall be
extended to the next day on which the Commission is open for business. The
Registration Statement required hereunder shall be on Form S-3 (or Form S-1 or
any other applicable form, at the sole discretion of the Company, if Form S-3 is
not available to the Company). Subject to the terms of this Agreement, the
Company shall use its commercially reasonable efforts to cause the Registration
Statement to be declared effective under the Securities Act as promptly as
possible after the filing thereof, and shall use its commercially reasonable
efforts to keep the Registration Statement continuously effective under the
Securities Act until the date when all Registrable Securities covered by the
Registration Statement have been sold or may be sold without volume restrictions
pursuant to Rule 144, as determined by the counsel to the Holder (as defined
below) pursuant to a written opinion letter to such effect, addressed and
acceptable to the Company’s counsel, the Company’s transfer agent and the
affected Holders (the “Effectiveness Period”).  By 9:30 a.m. EDT on the Business
Day following the date that the Registration Statement is declared effective by
the Commission, the Company shall file with the Commission in accordance with
Rule 424 under the Securities Act the final prospectus to be used in connection
with sales pursuant to such Registration Statement.
 
(b)           In the event the Company fails to file the Registration Statement
with the Commission on or before Registration Due Date, the Company shall pay to
each Purchaser, as liquidated damages and not as a penalty, an amount, for each
month (or portion of a month) in which such delay shall occur, equal to one
percent (1%) of the aggregate Purchase Price paid by each such Purchaser, until
the point in time when the Company has filed the Registration Statement with the
Commission or the expiration of the Effectiveness Period, whichever occurs
first.
 
 
21

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

 

(c)           The term “Registrable Securities” shall mean (i) all Shares sold
in the Offering, (ii) the Warrant Shares issuable upon exercise of all Warrants
sold in the Offering, and (iii) any shares of Common Stock issued or issuable
upon any stock split, dividend or other distribution, recapitalization or
similar event with respect to the foregoing; provided, however, that securities
shall only be treated as Registrable Securities if and only for so long as they
(i) have not been sold (A) pursuant to a registration statement; (B) to or
through a broker, dealer or underwriter in a public distribution or a public
securities transaction; and/or (C) in a transaction exempt from the registration
and prospectus delivery requirements of the Securities Act under Section 4(1)
thereof so that all transfer restrictions and restrictive legends with respect
thereto, if any, are removed upon the consummation of such sale; (ii) are held
by a Holder (as defined below) or a permitted transferee; and (iii) are not
eligible for sale without volume limitations pursuant to Rule 144 (or any
successor thereto) under the Securities Act.
 
(d)           The term “Holder” shall mean any person owning or having the right
to acquire Registrable Securities or any permitted transferee of a Holder.
 
4.2          Registration Procedures; Company. In connection with the Company’s
registration obligations set forth in Section 4.1 above, the Company shall:
 
(a)           Not less than five (5) business days prior to the filing of the
Registration Statement or any related prospectus or any amendment or supplement
thereto (i) furnish to the Holders copies of all such documents proposed to be
filed (other than those documents incorporated or deemed incorporated by
reference to the extent requested by such Person) which documents will be
subject to the review of such Holders and (ii) cause its officers, directors,
counsel and independent certified public accountants to respond to such
inquiries as shall be necessary, in the reasonable opinion of respective
counsel, to conduct a reasonable investigation within the meaning of the
Securities Act. The Company shall not file the Registration Statement or any
such prospectus or any amendments or supplements thereto to which the Holders of
a majority of the Registrable Securities shall reasonably object in good faith,
provided that the Company is notified of such objection in writing no later than
three (3) business days after the Holders have been so furnished copies of such
documents.
 
(b)           Prepare and file with the Commission such amendments, including
post-effective amendments, to the Registration Statement and the prospectus used
in connection therewith as may be necessary to keep the Registration Statement
continuously effective as to the applicable Registrable Securities for the
Effectiveness Period and prepare and file with the Commission such additional
Registration Statements in order to register for resale under the Securities Act
all of the Registrable Securities.
 
(c)           Use commercially reasonable efforts to avoid the issuance of, or,
if issued, obtain the withdrawal of (i) any order suspending the effectiveness
of the Registration Statement or (ii) any suspension of the qualification (or
exemption from qualification) of any of the Registrable Securities for sale in
any jurisdiction, at the earliest practicable moment.
 
(d)           Comply with all applicable rules and regulations of the
Commission.
 
(e)           Furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) 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 (ii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the Commission which permits
the selling of any such securities without registration or pursuant to such
form.
 
 
22

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

 
 
4.3           Registration Procedures; Purchaser. In connection with the
Company’s registration obligations set forth in Section 4.1 above:
 
(a)           The Purchaser shall cooperate with the Company, as requested by
the Company, in connection with the preparation and filing of any Registration
Statement hereunder. The Purchaser shall provide the Company with a completed
Selling Stockholder Questionnaire (in the form attached hereto as Exhibit B-3)
and such other information that the Company may reasonably require the Purchaser
to promptly furnish in writing to the Company as may be required in connection
with such registration including, without limitation, all such information as
may be requested by the Commission or FINRA or any state securities commission
and all such information regarding the Purchaser, the Registrable Securities
held by the Purchaser and the intended method of disposition of the Registrable
Securities. The Purchaser agrees to provide such information requested in
connection with such registration within five (5) business days after receiving
such written request. The Company shall not be responsible for any delays in
filing or obtaining or maintaining the effectiveness of the Registration
Statement caused by any Purchaser’s failure to timely provide a completed
Selling Stockholder Questionnaire or such other information requested by the
Company.
 
(b)           If, in the good faith judgment of the Company, it would be
detrimental to the Company or its stockholders for the Registration Statement to
be filed or for resales of Registrable Securities to be made pursuant to the
Registration Statement due to (i) the existence of a material development or
potential material development involving the Company that the Company would be
obligated to disclose in the Registration Statement, which disclosure would be
premature or otherwise inadvisable at such time or would have a material adverse
effect on the Company or its stockholders or (ii) a proposed filing of or use of
an existing registration statement in connection with a Company-initiated
registration of any class of its equity securities, which, in the good faith
judgment of the Company, would adversely effect or require premature disclosure
of the filing or use of such Company-initiated registration (notice thereof, a
“Blackout Notice”), upon receipt of a Blackout Notice from the Company, the
Purchaser shall immediately discontinue disposition of Registrable Securities
pursuant to the Registration Statement (the period during which such disposition
is discontinued, the “Blackout Period”) covering such Registrable Securities
until (i) the Company advises the Purchaser that the Blackout Period has
terminated and (ii) the Purchaser receives copies of a supplemented or amended
prospectus, if necessary; provided, however, that (x) no Blackout Period shall
exceed thirty (30) consecutive days, (y) during any three hundred sixty five
(365) day period such Blackout Periods shall not exceed an aggregate of sixty
(60) days, and (z) the first day of any Blackout Period must be at least five
(5) Trading Days  after the last day of any prior Blackout Period. If so
directed by the Company, the Purchaser will deliver to the Company (at the
expense of the Company) or destroy (and deliver to the Company a certificate of
destruction) all copies in the Purchaser’s possession (other than a limited
number of file copies) of the prospectus covering such Registrable Securities
that is current at the time of receipt of such notice.
 
(c)           If the Purchaser determines to engage an underwriter (other than
the Purchaser) in connection with the offering of any Registrable Securities (an
“Underwritten Offering”), the Purchaser will enter into and perform its
obligations under an underwriting agreement, in usual and customary form,
including, without limitation, customary indemnification and contribution
obligations, with the managing underwriter of such offering, and will take such
other actions as are reasonably required in order to expedite or facilitate the
disposition of the Registrable Securities. The Purchaser shall consult with the
Company prior to any Underwritten Offering and shall defer such Underwritten
Offering for a reasonable period upon the request of the Company.
 
 
23

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

 
 
(d)           The Purchaser shall not take any action with respect to any
distribution deemed to be made pursuant to the Registration Statement, which
would constitute a violation of Regulation M under the Exchange Act or any other
applicable rule, regulation or law.
 
4.4          Registration Expenses. All fees and expenses of the Company
incident to the performance of or compliance with Section 4.1 and Section 4.2
hereof by the Company shall be borne by the Company. In addition, the Company
shall reimburse the Holders, on a one-time basis, for the reasonable fees and
expenses of counsel to the Holders of up to $5,000 in the aggregate with respect
to the review of any registration statement filed pursuant to Section 4.1
hereof, as directed by the then Holders of a majority of the Registrable
Securities.
 
4.5          Indemnification. In the event that any Registrable Securities are
included in a Registration Statement under this ARTICLE IV:
 
(a)           To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, any underwriter (as defined in the Securities Act)
for such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Securities Act or the Exchange Act, against any
losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the Securities Act, or the Exchange Act, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereof) arise
out of or are based upon any of the following statements, omissions or
violations (collectively a “Violation”): (i) any untrue statement or alleged
untrue statement of a material fact contained in such registration statement,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Securities Act, the Exchange Act, or any rule or
regulation promulgated under the Securities Act, or the Exchange Act, and the
Company will pay to each such Holder, underwriter or controlling person, as
incurred, any legal or other expenses reasonably incurred by them in connection
with investigating or defending any such loss, claim, damage, liability, or
action; provided, however, that the indemnity agreement contained in this
Section 4.5(a) shall not apply to amounts paid in settlement of any such loss,
claim, damage, liability, or action if such settlement is effected without the
consent of the Company (which consent shall not be unreasonably withheld), nor
shall the Company be liable in any such case for any such loss, claim, damage,
liability, or action to the extent that it arises out of or is based upon a
Violation that occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by
any such Holder, underwriter or controlling person.
 
 
24

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

 

(b)           To the extent permitted by law, each Holder will indemnify and
hold harmless the Company, each of its directors, each of its officers, each
person, if any, who controls the Company within the meaning of the Securities
Act, any underwriter, any other Holder selling securities in such registration
statement and any controlling person of any such underwriter or other Holder,
against any losses, claims, damages, or liabilities (joint or several) to which
any of the foregoing persons may become subject, under the Securities Act, or
the Exchange Act, insofar as such losses, claims, damages, or liabilities (or
actions in respect thereto) 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 or omitted by
such Holder for use in connection with such registration; and each such Holder
will pay, as incurred, any legal or other expenses incurred by any person
intended to be indemnified pursuant to this Section 4.5(b), in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this Section 4.5(b)
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability or action if such settlement is effected without the consent of the
Holder, which consent shall not be unreasonably withheld; provided, further,
that, in no event shall any indemnity under this Section 4.5(b) exceed the
greater of the cash value of the (i) gross proceeds from the offering received
by such Holder or (ii) such Holder’s investment pursuant to this Agreement as
set forth on the signature page attached hereto.
 
(c)           Promptly after receipt by an indemnified party under this
Section 4.5 of notice of the commencement of any action (including any
governmental action), such indemnified party shall, if a claim in respect
thereof is to be made against any indemnifying party under this Section 4.5,
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 notified, to assume the defense thereof with counsel selected by
the indemnifying party and approved by the indemnified party (whose approval
shall not be unreasonably withheld); provided, however, that an indemnified
party (together with all other indemnified parties which may be represented
without conflict by one counsel) shall have the right to retain one separate
counsel, with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this
Section 4.5, but the omission so to deliver written notice to the indemnifying
party will not relieve it of any liability that it may have to any indemnified
party otherwise than under this Section 4.5.
 
(d)           If the indemnification provided for in this Section 4.5 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the alleged omission to state a material
fact relates to information supplied by the indemnifying party or by the
indemnified party and the parties’ relative intent, knowledge, access to
information, and opportunity to correct or prevent such statement or omission.
 
 
25

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

 
 
(e)           The obligations of the Company and Holders under this Section 4.5
shall survive the completion of any offering of Registrable Securities in a
Registration Statement under this ARTICLE IV, and otherwise.
 
4.6           Cutback. In connection with filing the Registration Statement
pursuant to Section 4.1 hereof, the obligations of the Company set forth in this
ARTICLE IV are subject to any limitations on the Company’s ability to register
the full complement of such shares in accordance with Rule 415 under the
Securities Act or other regulatory limitations. To the extent the number of such
shares that can be registered is limited, the Company shall file a subsequent
registration agreement that will provide, among other things, that the Company
will use its commercially reasonable efforts to register additional tranches of
Registrable Securities as soon as permissible thereafter under applicable laws,
rules and regulations so that all of such Registrable Securities are registered
as soon as reasonably practicable.
 
4.7           Sales by Purchasers. The Purchaser shall sell any and all
Registrable Securities (as defined below) purchased hereby in compliance with
applicable prospectus delivery requirements, if any, or otherwise in compliance
with the requirements for an exemption from registration under the Securities
Act and the rules and regulations promulgated thereunder. The Purchaser will not
make any sale, transfer or other disposition of the Securities in violation of
federal or state securities or “blue sky” laws and regulations.
 
4.8           Piggy-Back Registrations. If at any time during the Effectiveness
Period there is not an effective Registration Statement covering all of the
Registrable Securities and the Company shall determine to prepare and file with
the Commission a registration statement relating to an offering for its own
account or the account of others under the Securities Act of any of its equity
securities, other than on Form S-4 or Form S-8 (each as promulgated under the
Securities Act) or their then equivalents relating to equity securities to be
issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with the stock option or other employee
benefit plans, then the Company shall send to each Holder a written notice of
such determination and, if within 15 days after the date of such notice, any
such Holder shall so request in writing, the Company shall include in such
registration statement all or any part of such Registrable Securities such
Holder requests to be registered, subject to customary underwriter cutbacks
applicable to all holders of registration rights and any limitations imposed by
applicable law.
 
4.9           Waivers. With the written consent of the Company and the Holders
holding at least a majority of the Registrable Securities that are then
outstanding, any provision of this ARTICLE IV may be waived (either generally or
in a particular instance, either retroactively or prospectively and either for a
specified period of time or indefinitely) or amended, which waiver shall be
applicable to all Holders, and shall be deemed to have been consented to by all
Holders. Upon the effectuation of each such waiver or amendment, the Company
shall promptly give written notice thereof to the Holders, if any, who have not
previously received notice thereof or consented thereto in writing.

 
26

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

 
 
ARTICLE V.
OTHER AGREEMENTS OF THE PARTIES
 
5.1          Transfers; Certificates.

 
(a)           Compliance with Laws.  Notwithstanding any other provision of this
Agreement, each Purchaser covenants that the securities may be disposed of only
pursuant to an effective registration statement under, and in compliance with
the requirements of, the Securities Act, or pursuant to an available exemption
from, or in a transaction not subject to, the registration requirements of the
Securities Act, and in compliance with any applicable state and federal
securities laws.  In connection with any transfer of the Securities other than
(i) pursuant to an effective registration statement, (ii) to the Company, (iii)
to an Affiliate of a Purchaser, (iv) pursuant to Rule 144 (provided that the
Purchaser provides the Company with reasonable assurances (in the form of seller
and broker representation letters or an opinion of counsel, as appropriate,)
that the securities may be sold pursuant to such rule) or Rule 144A, or (v) in
connection with a bona fide pledge as contemplated in Section 5.1(b), except as
otherwise provided herein, the Company may require the transferor thereof to
provide to the Company an opinion of counsel selected by the transferor and
reasonably acceptable to the Company, the form and substance of which opinion
shall be reasonably satisfactory to the Company, to the effect that such
transfer does not require registration of such transferred Securities under the
Securities Act.  As a condition of transfer, any such transferee shall agree in
writing to be bound by the terms of this Agreement and shall have the rights of
a Purchaser under this Agreement, including ARTICLE IV hereof.
 
(b)           Legends.  Certificates evidencing the Securities shall bear any
legend as required by the “blue sky” laws of any applicable state and a
restrictive legend in substantially the following form, until such time as they
are not required under Section 5.1(c):
 
[NEITHER THESE SECURITIES NOR THE SECURITIES ISSUABLE UPON EXERCISE OF THESE
SECURITIES HAVE BEEN REGISTERED] [THESE SECURITIES HAVE NOT BEEN REGISTERED]
WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY
STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT
OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED
OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE
SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION
NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN
ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS AS EVIDENCED
BY A LEGAL OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY.
 
 
27

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

 

           The Company acknowledges and agrees that a Purchaser may from time to
time pledge, and/or grant a security interest in, some or all of the legended
Securities in connection with applicable securities laws, pursuant to a bona
fide margin agreement in compliance with a bona fide margin loan.  Such a pledge
would not be subject to approval or consent of the Company and no legal opinion
of legal counsel to the pledgee, secured party or pledgor shall be required in
connection with the pledge, but such legal opinion shall be required in
connection with a subsequent transfer or foreclosure following default by the
Purchaser's transferee of the pledge.  No notice shall be required of such
pledge, but Purchaser’s transferee shall promptly notify the Company of any such
subsequent transfer or foreclosure.  Each Purchaser acknowledges that the
Company shall not be responsible for any pledges relating to, or the grant of
any security interest in, any of the Securities or for any agreement,
understanding or arrangement between any Purchaser and its pledgee or secured
party.  At the appropriate Purchaser’s expense, the Company will execute and
deliver such reasonable documentation as a pledgee or secured party of Shares
may reasonably request in connection with a pledge or transfer of the Shares,
including the preparation and filing of any required prospectus supplement under
Rule 424(b)(3) of the Securities Act or other applicable provision of the
Securities Act to appropriately amend the list of Selling Stockholders
thereunder.  Each Purchaser acknowledges and agrees that, except as otherwise
provided in Section 5.1(c), any Shares subject to a pledge or security interest
as contemplated by this Section 5.1(b) shall continue to bear the legend set
forth in this Section 5.1(b) and be subject to the restrictions on transfer set
forth in Section 5.1(a).
 
(c)           Removal of Legends.  The legend set forth in Section 5.1(b) above
shall be removed and the Company shall issue a certificate without such legend
to the holder of the Securities upon which it is stamped or issue to such holder
by electronic delivery at the applicable balance account at The Depository Trust
Company (“DTC”), if (i) such Securities are registered for resale under the
Securities Act, (ii) such Securities are sold or transferred pursuant to Rule
144 (assuming the transferor is not an Affiliate of the Company) or Rule 144A,
or (iii) such Securities are eligible for sale under Rule 144 without
application of the requirements of paragraph (c)(i) thereof.  The Company shall
cause its counsel to issue the legal opinion referred to in the Irrevocable
Transfer Agent Instructions to the Company’s transfer agent on the Effective
Date.  Any fees (with respect to the Transfer Agent, counsel to the Company or
otherwise) associated with the issuance of such opinion or the removal of such
legend shall be borne by the Company.  If any portion of the Warrant is
exercised at a time when there is an effective registration statement to cover
the resale of the Warrant Shares, or if such Warrant Shares may be sold under
Rule 144 without application of the requirements of paragraph (c)(i) thereof,
then such Warrant Shares shall be issued free of all legends.  Following the
Effective Date, or at such earlier time as a legend is no longer required for
certain Securities, the Company will no later than three (3) Trading Days
following the delivery by a Purchaser to the Company or the Transfer Agent (with
notice to the Company) of (i) a legended certificate representing such Shares or
Warrant Shares (endorsed or with stock powers attached, signatures guaranteed,
and otherwise in form necessary to affect the reissuance and/or transfer) or
(ii) an Exercise Notice in the manner stated in the Warrants to effect the
exercise of such Warrant in accordance with its terms and an opinion of counsel
to the extent required by Section 5.1(a), deliver or cause to be delivered to
such Purchaser a certificate representing such Securities that is free from all
restrictive and other legends.  The Company may not make any notation on its
records or give instructions to the Transfer Agent that enlarge the restrictions
on transfer set forth in this Section.
 
(d)           Irrevocable Transfer Agent Instructions. The Company shall issue
irrevocable instructions to its transfer agent, and any subsequent transfer
agent, to issue certificates or credit shares to the applicable balance accounts
at DTC, registered in the name of each Purchaser or its respective nominee(s),
for the Shares and the Warrant Shares in such amounts as specified from time to
time by each Purchaser to the Company in the form of Exhibit E attached hereto
(the “Irrevocable Transfer Agent Instructions”).
 
 
28

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

 

(e)           Acknowledgement.  Each Purchaser hereunder acknowledges its
primary responsibilities under the Securities Act and accordingly will not sell
any of the Securities or any interest therein without complying with the
requirements of the Securities Act.  While a Registration Statement remains
effective, each Purchaser hereunder may sell the shares in accordance with the
plan of distribution contained in such Registration Statement and if it does so
it will comply therewith and with the related prospectus delivery requirements
unless an exemption therefrom is available.  Each Purchaser, severally and not
jointly with the other Purchasers, agrees that if it is notified by the Company
at any time after the date any legend is removed pursuant to Section 5.1(c)
hereof that no Registration Statement is effective or that the prospectus
included in any such Registration Statement no longer complies with the
requirements of Section 10 of the Securities Act, the Purchaser will refrain
from selling such Shares and Warrant Shares until such time as the Purchaser is
notified by the Company that a Registration Statement is effective or such
prospectus is compliant with Section 10 of the Exchange Act, unless such
Purchaser is able to, and does, sell such Shares or Warrant Shares pursuant to
an available exemption from the registration requirements of Section 5 of the
Securities Act.  Each Purchaser, severally and not jointly with the other
Purchasers, agrees to indemnify the Company and Company Counsel for any damages
or losses resulting to the Company from the Purchaser’s breach of its covenants
set forth in the preceding sentence.
 
5.2           Reservation of Common Stock.  The Company shall take all action
necessary to at all times have authorized, and reserved for the purpose of
issuance from and after the Closing Date, no less than 100% of the number of
shares of Common Stock issuable upon exercise of the Warrants issued at the
Closing (without taking into account any limitations on exercise of the Warrants
set forth in the Warrants).
 
5.3           Furnishing of Information.  In order to enable the Purchasers to
sell the Securities under Rule 144 of the Securities Act, for a period of one
year from the Closing, the Company shall use its commercially reasonable efforts
to timely file (or obtain extensions in respect thereof and file within the
applicable grace period) all reports required to be filed by the Company after
the date hereof pursuant to the Exchange Act.  During such one year period, if
the Company is not required to file reports pursuant to such laws, it will
prepare and furnish to the Purchasers and make publicly available in accordance
with Rule 144(c) such information as is required for the Purchasers to sell the
Shares and Warrant Shares under Rule 144. The Company further covenants that it
will take such further action as any holder of Securities may reasonably

sell the Shares and Warrant Shares without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144.
 
5.4           Reporting Status.  During the one year period from and after the
Closing, the Company shall not terminate its status as an issuer required to

respect to the sale of the Shares and Warrants as required under Regulation D
and to provide a copy thereof to the Placement Agent promptly after such
filing.  The Company, on or before the Closing Date, shall take such action as
the Company shall reasonably determine is necessary in order to obtain an
exemption for or to qualify the Securities for sale to the Purchasers at the
Closing pursuant to this Agreement under applicable securities or “Blue Sky”
laws of the states of the United States (or to obtain an exemption from such
qualification), and shall provide evidence of any such action so taken to the
Placement Agent on or prior to the Closing Date.  The Company shall make all
filings and reports relating to the offer and sale of the Securities required
under applicable securities or “Blue Sky” laws of the states of the United
States following the Closing Date.

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

 
 
5.6           No Integration.  The Company shall not, and shall use its best
efforts to ensure that no Affiliate of the Company shall, sell, offer for sale
or solicit offers to buy or otherwise negotiate in respect of any security (as
defined in Section 2 of the Securities Act) that will be integrated with the
offer or sale of the Securities in a manner that would require the registration
under the Securities Act of the sale of the Securities to the Purchasers, or
that will be integrated with the offer or sale of the Securities for purposes of
the rules and regulations of any Trading Market such that it would require
shareholder approval prior to the closing of such other transaction unless
shareholder approval is obtained before the closing of such subsequent
transaction.
 
5.7           Securities Laws Disclosure; Publicity.    By 9:00 a.m. (New York
City time) on the Trading Day immediately following the execution of this
Agreement, the Company shall issue a press release (the “Press Release”)
reasonably acceptable to the Placement Agent disclosing all material terms of
the transactions contemplated hereby.  On or prior to the fourth (4th) Business
Day following the date of this Agreement, the Company will file a Current Report
on Form 8-K with the Commission describing the terms of the Transaction
Documents (and including as exhibits to such Current Report on Form 8-K the
material Transaction Documents (including, without limitation, this Agreement
and the form of Warrant)). Each Purchaser, severally and not jointly with the
other Purchasers, covenants that until such time as the transactions
contemplated by this Agreement are publicly disclosed by the Company as
described in this Section 5.7, such Purchaser will maintain the confidentiality
of all disclosures made to it in connection with this transaction (including the
existence and terms of this transaction).
 
5.8           Listing of Securities.  Promptly following the date hereof, the
Company shall take all necessary action to cause the Shares, the Warrant Shares
and the shares of Common Stock issuable upon exercise of the Placement Agent’s
Warrant to be listed upon the Principal Trading Market, if any, upon which
shares of Common Stock are then listed (subject to official notice of issuance)
and shall maintain, so long as any other shares of Common Stock shall be so
listed, such listing.  Further, if the Company applies to have its Common Stock
or other securities listed on any other Trading Market, it shall include in such
application the Shares and the Warrant Shares (including the shares of Common
Stock issuable upon exercise of the warrants issued to the Placement Agent) and
will take such other action as is necessary to cause the Shares, and the Warrant
Shares (including the shares of Common Stock issuable upon exercise of the
warrants issued to the Placement Agent) to be listed on such other Trading
Market as promptly as practicable.
 
5.9           Use of Proceeds.  The Company intends to use the net proceeds
resulting from the sale of the Securities for general corporate purposes, which
may include working capital, capital expenditures, research and development
expenditures, pre-clinical and clinical trial expenditures, acquisitions of new
technologies or businesses that are complementary to our current technologies or
business focus, and investments. As of the date of this Agreement, the Company
cannot specify with certainty all of the particular uses of the net proceeds
from the sale of the Securities. As a result, Purchasers acknowledge that the
Company’s management will retain broad discretion in the allocation and use of
such proceeds.
 
 
30

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

 

5.10            Sales and Confidentiality After the Date Hereof.  Such Purchaser
shall not, and shall cause its Trading Affiliates not to, engage, directly or
indirectly, in any transactions in the securities of the Company (including,
without limitation, any Short Sales) during the period from the date hereof
until such time as (i) the transactions contemplated by this Agreement are first
publicly announced as described in Section 5.7 or (ii) this Agreement is
terminated in full pursuant to Section 7.16.  Notwithstanding the foregoing, in
the case of a Purchaser that is a multi-managed investment vehicle whereby
separate portfolio managers manage separate portions of such Purchaser's assets
and the portfolio managers have no direct knowledge of the investment decisions
made by the portfolio managers managing other portions of such Purchaser's
assets, the representation set forth above shall apply only with respect to the
portion of assets managed by the portfolio manager that have knowledge about the
financing transaction contemplated by this Agreement.  Each Purchaser
understands and acknowledges, severally and not jointly with any other
Purchaser, that the Commission currently takes the position that covering a
short position established prior to effectiveness of a resale registration
statement with shares included in such registration statement would be a
violation of Section 5 of the Securities Act, as set forth in Item 65, Section 5
under Section A, of the Manual of Publicly Available Telephone Interpretations,
dated July 1997, compiled by the Office of Chief Counsel, Division of
Corporation Finance.
 
5.11           Equal Treatment of Purchasers.  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 the Transaction Documents unless the same consideration is
also offered to all of the parties to the Transaction Documents.  For
clarification purposes, this provision constitutes a separate right granted to
each Purchaser by the Company and negotiated separately by each Purchaser, and
is intended for the Company to treat the Purchasers as a class and shall not in
any way be construed as the Purchasers acting in concert or as a group with
respect to the purchase, disposition or voting of Shares or otherwise.
 
5.12           Indemnification.  Subject to the provisions of this Section 5.12,
the Company will indemnify and hold each Purchaser and its directors, officers,
shareholders, members, partners, employees and agents (and any other Persons
with a functionally equivalent role of a Person holding such titles
notwithstanding a lack of such title or any other title), each Person who
controls such Purchaser (within the meaning of Section 15 of the Securities Act
and Section 20 of the Exchange Act), and the directors, officers, shareholders,
agents, members, partners or employees (and any other Persons with a
functionally equivalent role of a Person holding such titles notwithstanding a
lack of such title or any other title) of such controlling persons (each, a
“Purchaser Party”) harmless from any and all losses, liabilities, obligations,
claims, contingencies, damages, costs and expenses, including all judgments,
amounts paid in settlements, court costs and reasonable attorneys’ fees and
costs of investigation that any such Purchaser Party may suffer or incur as a
result of or relating to (a) any breach of any of the representations,
warranties, covenants or agreements made by the Company in this Agreement or in
the other Transaction Documents or (b) any action instituted against a
Purchaser, or any of them or their respective Affiliates, by any stockholder of
the Company who is not an Affiliate of such Purchaser, with respect to any of
the transactions contemplated by the Transaction Documents (unless such action
is based upon a breach of such Purchaser’s representations, warranties or
covenants under the Transaction Documents or any agreements or understandings
such Purchaser may have with any such stockholder or any violations by the
Purchaser of state or federal securities laws or any conduct by such Purchaser
which constitutes fraud, gross negligence, willful misconduct or
malfeasance).  If any action shall be brought against any Purchaser Party in
respect of which indemnity may be sought pursuant to this Agreement, such
Purchaser Party shall promptly notify the Company in writing, and the Company
shall have the right to assume the defense thereof with counsel of its own
choosing reasonably acceptable to the Purchaser Party.  Any Purchaser Party
shall have the right to employ separate counsel in any such action and
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of such Purchaser Party except to the extent that
(i) the employment thereof has been specifically authorized by the Company in
writing, (ii) the Company has failed after a reasonable period of time to assume
such defense and to employ counsel or (iii) in such action there is, in the
reasonable opinion of such separate counsel, a material conflict on any material
issue between the position of the Company and the position of such Purchaser
Party, in which case the Company shall be responsible for the reasonable fees
and expenses of no more than one such separate counsel.  The Company will not be
liable to any Purchaser Party under this Agreement (i) for any settlement by a
Purchaser Party effected without the Company’s prior written consent, which
shall not be unreasonably withheld or delayed; or (ii) to the extent, but only
to the extent that a loss, claim, damage or liability is attributable to (A) any
Purchaser Party’s breach of any of the representations, warranties, covenants or
agreements made by such Purchaser Party in this Agreement or in the other
Transaction Documents, (B) any violations by the Purchaser of state or federal
securities laws or (C) any conduct by such Purchaser which constitutes fraud,
gross negligence, willful misconduct or malfeasance.

Courts.  Each party hereto hereby irrevocably submits to the exclusive
jurisdiction of the New York Courts for the adjudication of any dispute
hereunder or in connection herewith or with any transaction contemplated hereby
or discussed herein (including with respect to the enforcement of any of the
Transaction Documents), and hereby irrevocably waives, and agrees not to assert
in any Action, any claim that it is not personally subject to the jurisdiction

parties need not sign the same counterpart.  In the event that any signature is
delivered by facsimile transmission, or by e-mail delivery of a “.pdf” format
data file, such signature shall create a valid and binding obligation of the
party executing (or on whose behalf such signature is executed) with the same
force and effect as if such facsimile signature page were an original thereof.
 
7.11         Severability.  If any provision of this Agreement is held to be
invalid or unenforceable in any respect, the validity and enforceability of the
remaining terms and provisions of this Agreement shall not in any way be
affected or impaired thereby and the parties will attempt to agree upon a valid
and enforceable provision that is a reasonable substitute therefor, and upon so
agreeing, shall incorporate such substitute provision in this Agreement.
 
 
36

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

 
 
7.12         Rescission and Withdrawal Right.  Notwithstanding anything to the
contrary contained in (and without limiting any similar provisions of) the
Transaction Documents, whenever any Purchaser exercises a right, election,
demand or option under a Transaction Document and the Company does not timely
perform its related obligations within the periods therein provided, then such
Purchaser may rescind or withdraw, in its sole discretion from time to time upon
written notice to the Company, any relevant notice, demand or election in whole
or in part without prejudice to its future actions and rights.
 
7.13         Replacement of Securities.  If any certificate or instrument
evidencing any Securities is mutilated, lost, stolen or destroyed, the Company
shall issue or cause to be issued in exchange and substitution for and upon
cancellation thereof, or in lieu of and substitution therefor, a new certificate
or instrument, but only upon receipt of evidence reasonably satisfactory to the
Company and the Transfer Agent of such loss, theft or destruction and the
execution by the holder thereof of a customary lost certificate affidavit of
that fact and an agreement to indemnify and hold harmless the Company and the
Transfer Agent for any losses in connection therewith or, if required by the
Transfer Agent, a bond in such form and amount as is reasonably required by the
Transfer Agent.  The applicants for a new certificate or instrument under such
circumstances shall also pay any reasonable third-party costs associated with
the issuance of such replacement Securities.  If a replacement certificate or
instrument evidencing any Securities is requested due to a mutilation thereof,
the Company may require delivery of such mutilated certificate or instrument as
a condition precedent to any issuance of a replacement.
 
7.14         Adjustments in Share Numbers and Prices. In the event of any stock
split, subdivision, dividend or distribution payable in shares of Common Stock
(or other securities or rights convertible into, or entitling the holder thereof
to receive directly or indirectly shares of Common Stock), combination or other
similar recapitalization or event occurring after the date hereof, each
reference in any Transaction Document to a number of shares or a price per share
shall be deemed to be amended to appropriately account for such event.
 
7.15         Independent Nature of Purchasers’ Obligations and Rights.  The
obligations of each Purchaser under any Transaction Document are several and not
joint with the obligations of any other Purchaser, and no Purchaser shall be
responsible in any way for the performance of the obligations of any other
Purchaser under any Transaction Document.  The decision of each Purchaser to
purchase Securities pursuant to the Transaction Documents has been made by such
Purchaser independently of any other Purchaser and independently of any
information, materials, statements or opinions as to the business, affairs,
operations, assets, properties, liabilities, results of operations, condition
(financial or otherwise) or prospects of the Company which may have been made or
given by any other Purchaser or by any agent or employee of any other Purchaser,
and no Purchaser and any of its agents or employees shall have any liability to
any other Purchaser (or any other Person) relating to or arising from any such
information, materials, statement or opinions.  Nothing contained herein or in
any Transaction Document, and no action taken by any Purchaser pursuant thereto,
shall be deemed to constitute the Purchasers as a partnership, an association, a
joint venture or any other kind of entity, or create a presumption that the
Purchasers are in any way acting in concert or as a group with respect to such
obligations or the transactions contemplated by the Transaction Documents.  Each
Purchaser acknowledges that no other Purchaser has acted as agent for such
Purchaser in connection with making its investment hereunder and that no
Purchaser will be acting as agent of such Purchaser in connection with
monitoring its investment in the Securities or enforcing its rights under the
Transaction Documents.  Each Purchaser shall be entitled to independently
protect and enforce its rights, including without limitation the rights arising
out of this Agreement or out of the other Transaction Documents, and it shall
not be necessary for any other Purchaser to be joined as an additional party in
any proceeding for such purpose.  The Company acknowledges that each of the
Purchasers has been provided with the same Transaction Documents for the purpose
of closing a transaction with multiple Purchasers and not because it was
required or requested to do so by any Purchaser. The Company’s obligations to
each Purchaser under this Agreement are identical to its obligations to each
other Purchaser other than such differences resulting solely from the number of
Securities purchased by such Purchaser, but regardless of whether such
obligations are memorialized herein or in another agreement between the Company
and a Purchaser.
 
 
37

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

 
 
7.16         Termination. This Agreement may be terminated and the sale and
purchase of the Shares and the Warrants abandoned at any time prior to the
Closing by either the Company or any Purchaser (with respect to itself only)
upon written notice to the other, if the Closing has not been consummated on or
prior to 5:00 p.m. (New York City time) on the Outside Date; provided, however,
that the right to terminate this Agreement under this Section 6.16 shall not be
available to any Person whose failure to comply with its obligations under this
Agreement has been the cause of or resulted in the failure of the Closing to
occur on or before such time.  Nothing in this Section 7.16 shall be deemed to
release any party from any liability for any breach by such party of the terms
and provisions of this Agreement or the other Transaction Documents or to impair
the right of any party to compel specific performance by any other party of its
obligations under this Agreement or the other Transaction Documents.  In the
event of a termination pursuant to this Section, the Company shall promptly
notify all non-terminating Purchasers.  Upon a termination in accordance with
this Section, the Company and the terminating Purchaser(s) shall not have any
further obligation or liability (including arising from such termination) to the
other, and no Purchaser will have any liability to any other Purchaser under the
Transaction Documents as a result therefrom.
