    d.           "Registrable Securities" means

    2.           REGISTRATION.

    


    a.           Mandatory
Registration.  The Company shall within thirty (30) Business
Days from the date hereof file with the SEC the Registration
Statement.  The Registration Statement shall register the Registrable
Securities and 194,596 other shares of the Company subject to prior registration
rights.  The Investor and its counsel shall have a reasonable
opportunity to review and comment upon such registration statement or amendment
to such registration statement and any related prospectus prior to its filing
with the SEC.  Investor shall furnish all information reasonably
requested by the Company for inclusion therein.  The Company shall use
its best efforts to have the Registration Statement or amendment declared
effective by the SEC at the earliest possible date.  The Company shall
use reasonable best efforts to keep the Registration Statement effective
pursuant to Rule 415 promulgated under the 1933 Act and available for sales of
all of the Registrable Securities at all times until the earlier of (i) the date
as of which the Investor may sell all of the Registrable Securities without
restriction pursuant to Rule 144(k) promulgated under the 1933 Act (or successor
thereto) or (ii) the date on which (A) the Investor shall have sold all the
Registrable Securities and no Available Amount remains under the Purchase
Agreement (the "Registration
Period").  The 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 light of the
circumstances in which they were made, not misleading.

    


    b.           Rule 424
Prospectus.  The Company shall, as required by applicable
securities regulations, from time to time file with the SEC, pursuant to Rule
424 promulgated under the 1933 Act, the prospectus and prospectus supplements,
if any, to be used in connection with sales of the Registrable Securities under
the Registration Statement.  The Investor and its counsel shall have a
reasonable opportunity to review and comment upon such prospectus prior to its
filing with the SEC. The Investor shall use its reasonable best efforts to
comment upon such prospectus within one (1) Business Day from the date the
Investor receives the final version of such prospectus.

    


    c.           Sufficient Number of Shares
Registered.  In the event the number of shares available under
the Registration Statement is insufficient to cover all of the Registrable
Securities, the Company shall amend the Registration Statement or file a new
registration statement (a ”New
Registration Statement”), so as to cover all of such Registrable
Securities as soon as practicable, but in any event not later than ten (10)
Business Days after the necessity therefor arises.  The Company shall
use it reasonable best efforts to cause such amendment and/or New Registration
Statement to become effective as soon as practicable following the filing
thereof.

    


    
      
         

      

      
        -29-

        
          

        

      

      
         

      

    

    3.           RELATED
OBLIGATIONS.

    


    With
respect to the Registration Statement and whenever any Registrable Securities
are to be registered pursuant to Section 2(b) including on any New Registration
Statement, the Company shall use its reasonable 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:

    


    a.           The
Company shall prepare and file with the SEC such amendments (including
post-effective amendments) and supplements to any 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 the Registration Statement or any New 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 the Registration Statement
or any New 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.

    


    b.           The
Company shall permit the Investor to review and comment upon the Registration
Statement or any New Registration Statement and all amendments and supplements
thereto at least two (2) Business Days prior to their filing with the SEC, and
not file any document in a form to which Investor reasonably
objects.  The Investor shall use its reasonable best efforts to
comment upon the Registration Statement or any New Registration Statement and
any amendments or supplements thereto within two (2) Business Days from the date
the Investor receives the final version thereof.  The Company shall
furnish to the Investor, without charge any correspondence from the SEC or the
staff of the SEC to the Company or its representatives relating to the
Registration Statement or any New Registration Statement.

    


    c.           Upon
request of the Investor, the Company shall furnish to the Investor, (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 and
all exhibits, (ii) upon the effectiveness of any registration statement, a copy
of the prospectus included in such registration statement and all amendments and
supplements thereto (or such other number of copies as the Investor may
reasonably request) and (iii) such other documents, including copies of any
preliminary or final prospectus, as the Investor may reasonably request from
time to time in order to facilitate the disposition of the Registrable
Securities owned by the Investor.

    


    d.           The
Company shall use reasonable best efforts to (i) register and qualify the
Registrable Securities covered by a registration statement under such other
securities or "blue sky" laws of such jurisdictions in the United States as the
Investor reasonably requests, (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(d), (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 the 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.

    


    
      
         

      

      
        -30-

        
          

        

      

      
         

      

    

    e.           As
promptly as practicable after becoming aware of such event or facts, the Company
shall notify the Investor in writing of the happening of any event or existence
of such facts as a result of which the prospectus included in any registration
statement, as then in effect, includes an untrue statement of a material fact or
omits 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, and promptly prepare a supplement or amendment to such
registration statement to correct such untrue statement or omission, and deliver
a copy of such supplement or amendment to the Investor (or such other number of
copies as the Investor may reasonably request).  The Company shall
also promptly notify the 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 the 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 any 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.

    


    f.           The
Company shall use its reasonable best efforts to prevent the issuance of any
stop order or other suspension of effectiveness of any registration statement,
or the suspension of the qualification of any 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 the Investor 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.

    


    g.           The
Company shall (i) cause all the Registrable Securities 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 on the Principal
Market. The Company shall pay all fees and expenses in connection with
satisfying its obligation under this Section.

    


    h.           The
Company shall cooperate with the Investor to facilitate the timely preparation
and delivery of certificates (not bearing any restrictive legend) representing
the Registrable Securities to be offered pursuant to any registration statement
and enable such certificates to be in such denominations or amounts as the
Investor may reasonably request and registered in such names as the Investor may
request.

    


    i.           The
Company shall at all times provide a transfer agent and registrar with respect
to its Common Stock.

    


    j.           If
reasonably requested by the Investor, the Company shall (i) immediately
incorporate in a prospectus supplement or post-effective amendment such
information as the Investor believes should 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 sold, the
purchase price being paid therefor and any other terms of the offering of the
Registrable Securities; (ii) make all required filings of such prospectus
supplement or post-effective amendment as soon as notified of the matters to be
incorporated in such prospectus supplement or post-effective amendment; and
(iii) supplement or make amendments to any registration statement.

    


    
      
         

      

      
        -31-

        
          

        

      

      
         

      

    

    k.           The
Company shall use its reasonable best efforts to cause the Registrable
Securities covered by the any 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.

    


    l.           Within
one (1) Business Day after any registration statement which includes the
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 Investor)
confirmation that such registration statement has been declared effective by the
SEC in the form attached hereto as Exhibit
A.  Thereafter, if requested by the Buyer at any time, the
Company shall require its counsel to deliver to the Buyer a written confirmation
whether or not the effectiveness of such registration statement has lapsed at
any time for any reason (including, without limitation, the issuance of a stop
order) and whether or not the registration statement is current and available to
the Buyer for sale of all of the Registrable Securities.

    


    m.           The
Company shall take all other reasonable actions necessary to expedite and
facilitate disposition by the Investor of Registrable Securities pursuant to any
registration statement.

    


    4.           OBLIGATIONS OF THE
INVESTOR.

    


    a.           The
Company shall notify the Investor in writing of the information the Company
reasonably requires from the Investor in connection with any registration
statement hereunder.  The 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 registration of such Registrable Securities
and shall execute such documents in connection with such registration as the
Company may reasonably request.

    


    b.           The
Investor agrees to cooperate with the Company as reasonably requested by the
Company in connection with the preparation and filing of any registration
statement hereunder.

    


    c.           The
Investor agrees that, upon receipt of any notice from the Company of the
happening of any event or existence of facts of the kind described in Section
3(f) or the first sentence of 3(e), the Investor will immediately discontinue
disposition of Registrable Securities pursuant to any registration statement(s)
covering such Registrable Securities until the Investor's receipt of the copies
of the supplemented or amended prospectus contemplated by Section 3(f) or the
first sentence of 3(e). Notwithstanding anything to the contrary, the Company
shall cause its transfer agent to promptly deliver shares of Common Stock
without any restrictive legend in accordance with the terms of the 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(f) or the first sentence of 3(e) and for which the
Investor has not yet settled.

    


    
      
         

      

      
        -32-

        
          

        

      

      
         

      

    

    5.           EXPENSES OF
REGISTRATION.

    


    All
reasonable expenses, other than sales or brokerage 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.

    


    6.           INDEMNIFICATION.

    


    a.           To
the fullest extent permitted by law, the Company will, and hereby does,
indemnify, hold harmless and defend the Investor, each Person, if any, who
controls the Investor, the members, the directors, officers, partners,
employees, agents, representatives of the Investor and each Person, if any, who
controls the Investor within the meaning of the 1933 Act or the Securities
Exchange Act of 1934, as amended (the "1934 Act") (each, an "Indemnified Person"), against
any losses, claims, damages, liabilities, judgments, fines, penalties, charges,
costs, 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 the Registration Statement, any New 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 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 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 sale of the Registrable Securities pursuant to the Registration Statement or
any New Registration Statement  or (iv) any material violation by the
Company of this Agreement (the matters in the foregoing clauses (i) through (iv)
being, collectively, "Violations").  The
Company shall reimburse each Indemnified Person 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 expressly for use in connection with
the preparation of the Registration Statement, any New Registration Statement or
any such amendment thereof or supplement thereto, if such prospectus was timely
made available by the Company pursuant to Section 3(c) or Section 3(e); (ii)
with respect to any superceded 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 superceded prospectus was corrected in the revised
prospectus, as then amended or supplemented, if such revised prospectus was
timely made available by the Company pursuant to Section 3(c) or Section 3(e),
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; (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, if such prospectus was timely made available by the Company pursuant to
Section 3(c) or Section 3(e); 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.  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 Investor
pursuant to Section 9.

    


    
      
         

      

      
        -33-

        
          

        

      

      
         

      

    

    b.           In
connection with the Registration Statement or any New Registration Statement,
the 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 or any New Registration Statement, each Person, if any,
who controls the Company within the meaning of the 1933 Act or the 1934 Act
(collectively and together with an Indemnified Person, 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 about the Investor set forth on Exhibit B attached
hereto and furnished to the Company by the Investor expressly for use in
connection with such registration statement; and, subject to Section 6(d), the
Investor will reimburse any legal or other expenses reasonably incurred by them
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 the Investor, which consent shall not be unreasonably
withheld; provided, further, however, that the 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 the 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 Investor pursuant to Section 9.

    


    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 to be
paid by the indemnifying party, if, in the reasonable opinion of counsel
retained by the indemnifying party, 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. 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 apprised 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 written consent, provided, however, that the indemnifying
party shall not unreasonably withhold, delay or condition its
consent.  No indemnifying party shall, without the 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
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.

    


    
      
         

      

      
        -34-

        
          

        

      

      
         

      

    

    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 seller of
Registrable Securities guilty of fraudulent misrepresentation (within the

    8.           REPORTS AND DISCLOSURE UNDER
THE SECURITIES ACTS.

    


    With a
view to making available to the Investor 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 Investor to sell securities of the Company to the public
without registration ("Rule
144"), the Company agrees, at the Company’s sole expense,
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 and the filing of such reports and other documents
is required for the applicable provisions of Rule 144; and

    


    
      
         

      

      
        -35-

        
          

        

      

      
         

      

    

    c.           furnish
to the Investor so long as the Investor owns Registrable Securities, promptly
upon request, (i) a written statement by the Company that it has complied with
the reporting and or disclosure provisions of Rule 144, the 1933 Act and the
1934 Act, (ii) a copy of the most recent annual or quarterly report of the
Company and such other reports and documents so filed by the Company, and (iii)
such other information as may be reasonably requested to permit the Investor to
sell such securities pursuant to Rule 144 without registration.

    


    d.           take
such additional action as is requested by the Investor to enable the Investor to
sell the Registrable Securities pursuant to Rule 144, including, without
limitation, delivering all such legal opinions, consents, certificates,
resolutions and instructions to the Company’s Transfer Agent as may be requested
from time to time by the Investor and otherwise fully cooperate with Investor
and Investor’s broker to effect such sale of securities pursuant to Rule
144.

    


    The Company agrees that damages may be
an inadequate remedy for any breach of the terms and provisions of this Section
8 and that Investor shall, whether or not it is pursuing any remedies at law, be
entitled to equitable relief in the form of a preliminary or permanent
injunction, without having to post any bond or other security, upon any breach
or threatened breach of any such terms or provisions.

or with any transaction contemplated hereby or discussed herein, and hereby
irrevocably waives, and agrees not to assert in any suit, action or proceeding,

or that the venue of such suit, action or proceeding is
improper.  Each party hereby irrevocably waives personal service of
process and consents to process being served in any such suit, action or
proceeding by mailing a copy thereof to such party at the address 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.
