and sale of the securities  contemplated by the Purchase Agreement (the "Closing
Date") but no later than thirty (30) days after the  Closing  Date (the  "Filing
Deadline"),  the Company  shall  prepare and file with the SEC one  Registration

on  such  form of  registration  statement  as is then  available  to  effect  a
registration for resale of the Registrable  Securities,  subject to the Required
Investors'  consent),  covering the resale of the  Registrable  Securities in an
amount at least equal to the Shares and the Warrant  Shares.  Subject to any SEC

to 1.5% of the aggregate amount invested by such Investor for each 30-day period
or pro rata for any portion  thereof  following the Filing Deadline for which no
Registration Statement is filed with respect to the Registrable Securities. Such
payments  shall  constitute the Investors'  exclusive  monetary  remedy for such
events,  but shall not  affect  the right of the  Investors  to seek  injunctive
relief. Such payments shall be made to each Investor in cash.


                                      -2-


                           (ii) S-3  QUALIFICATION.  Promptly following the date
(the  "Qualification  Date")  upon which the Company  becomes  eligible to use a
registration  statement on Form S-3 to register the  Registrable  Securities for
resale,  but in no event more than thirty (30) days after the Qualification Date
(the "Qualification  Deadline"), the Company shall file a registration statement
on Form S-3 covering the Registrable  Securities (or a post-effective  amendment

paid by such Investor pursuant to the Purchase  Agreement  attributable to those

pro  rata for any  portion  thereof  following  the  date by  which  such  Shelf
Registration   Statement  should  have  been  filed  for  which  no  such  Shelf
Registration Statement is filed with respect to the Registrable Securities. Such
payments  shall  constitute the Investors'  exclusive  monetary  remedy for such
events,  but shall not  affect  the right of the  Investors  to seek  injunctive
relief. Such payments shall be made to each Investor in cash.

                           (b)  EXPENSES.  The  Company  will  pay all  expenses
associated  with each  registration,  including  filing and printing  fees,  the
Company's  counsel and  accounting  fees and  expenses,  costs  associated  with
clearing the Registrable  Securities for sale under  applicable state securities
laws,  listing fees,  fees and expenses of one counsel to the Investors  (not to

registration,  but  excluding  discounts,  commissions,  fees  of  underwriters,
selling brokers,  dealer managers or similar securities  industry  professionals
with respect to the Registrable Securities being sold.

                           (c)      EFFECTIVENESS.

                           (i) The  Company  shall use  commercially  reasonable
efforts  to  have  the  Registration  Statement  declared  effective  as soon as

promptly as practicable, and in any event, prior to 9:00 a.m., New York time, on
the day after any Registration Statement is declared effective,  shall file with
the SEC under Rule 424 a final Prospectus as promptly as practicable, and in any
event,  prior to 9:00  a.m.,  New York time,  on the day after any  Registration
Statement is declared effective,  and shall advise the Investors in writing that


                                      -3-



either  (i) it has  complied  with  the  requirements  of Rule 172 or (ii) it is
unable to satisfy the  conditions  of Rule 172 and, as a result,  Investors  are
required to deliver a copy of the  Prospectus  in  connection  with any sales of
Registrable  Securities  (in  which  case,  the  Company  shall  deliver  to the
Investors a copy of the  Prospectus  to be used in  connection  with the sale or
other disposition of the securities  covered thereby).  If (A)(x) a Registration
Statement  covering the Registrable  Securities is not declared effective by the
SEC prior to the earlier of (i) five (5) Business  Days after the SEC shall have
informed the Company that no review of the  Registration  Statement will be made
or that the SEC has no further  comments on the  Registration  Statement or (ii)
the 90th day after the Closing Date (the 120th day after the Closing Date if the
SEC  comments  on  the  Registration  Statement)  or  (y) a  Shelf  Registration
Statement is not declared effective by the SEC within ninety (90) days after the
Qualification  Deadline  (120 days after the  Qualification  Deadline if the SEC
comments  on the Shelf  Registration  Statement),  or (B)  after a  Registration
Statement has been declared  effective by the SEC, sales cannot be made pursuant
to such Registration  Statement for any reason (including  without limitation by
reason of a stop  order,  or the  Company's  failure to update the  Registration
Statement),  but excluding the inability of any Investor to sell the Registrable
Securities  covered  thereby  due to market  conditions  and  except as  excused
pursuant  to  subparagraph  (ii)  below,  then the  Company  will  make pro rata
payments to each  Investor,  as liquidated  damages and not as a penalty,  in an
amount equal to 1.5% of the aggregate  amount invested by such Investor for each
30-day  period or pro rata for any portion  thereof  following the date by which
such Registration  Statement should have been effective (the "Blackout Period").
Such payments shall constitute the Investors' exclusive monetary remedy for such
events,  but shall not  affect  the right of the  Investors  to seek  injunctive
relief.  The amounts  payable as liquidated  damages  pursuant to this paragraph
shall be paid monthly  within  three (3)  Business  Days of the last day of each
month following the commencement of the Blackout Period until the termination of
the Blackout Period. Such payments shall be made to each Investor in cash.

                           (ii)   For not more than twenty (20) consecutive days
or for a total of not more than  forty-five  (45) days in any twelve  (12) month
period, the Company may delay the disclosure of material non-public  information
concerning the Company,  by suspending the use of any Prospectus included in any
registration  contemplated  by this Section  containing  such  information,  the
disclosure  of which  at the  time is not,  in the  good  faith  opinion  of the
Company,  in the best interests of the Company (an "Allowed  Delay");  provided,
that the  Company  shall  promptly  (a) notify the  Investors  in writing of the
existence of (but in no event, without the prior written consent of an Investor,
shall the Company  disclose to such  Investor any of the facts or  circumstances
regarding) material non-public  information giving rise to an Allowed Delay, (b)
advise  the  Investors  in  writing  to cease all sales  under the  Registration
Statement until the end of the Allowed Delay and (c) use commercially reasonable
efforts to terminate an Allowed Delay as promptly as practicable.

                           (d) LIMITATION ON LIQUIDATED DAMAGES. Notwithstanding
the other  provisions of this Section 2, in no event shall the Company be liable
for liquidated  damages in excess of an aggregate of 24% of the aggregate amount
invested by the Investors pursuant to the Purchase Agreement.

                                      -4-

alleged  omission to state therein a material fact required to be stated therein
or necessary to make the statements  therein not misleading;  (iv) any violation
by the  Company or its agents of any rule or  regulation  promulgated  under the
1933 Act  applicable  to the  Company or its agents  and  relating  to action or
inaction  required of the Company in connection with such  registration;  or (v)
any failure to register or qualify the  Registrable  Securities  included in any
such Registration in any state where the Company or its agents has affirmatively
undertaken  or  agreed  in  writing  that  the  Company  will   undertake   such
registration or  qualification  on an Investor's  behalf and will reimburse such
Investor,  and each such officer,  director or member and each such  controlling
person for 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 Company will not be liable in any such case
if and to the extent that any such loss,  claim,  damage or liability arises out
of or is based upon an untrue  statement or alleged untrue statement or omission
or alleged  omission so made in conformity  with  information  furnished by such
Investor or any such controlling person in writing  specifically for use in such
Registration Statement or Prospectus.

                           (b)  INDEMNIFICATION BY THE INVESTORS.  Each Investor
agrees,  severally  but not jointly,  to  indemnify  and hold  harmless,  to the
fullest  extent  permitted  by  law,  the  Company,  its  directors,   officers,
employees,  stockholders  and each person who controls  the Company  (within the
meaning of the 1933 Act) against any losses,  claims,  damages,  liabilities and
expense (including reasonable attorney fees) resulting from any untrue statement
of a material  fact or any omission of a material  fact required to be stated in
the Registration  Statement or Prospectus or preliminary Prospectus or amendment
or  supplement   thereto  or  necessary  to  make  the  statements  therein  not
misleading,  to the extent, but only to the extent that such untrue statement or
omission is contained in any  information  furnished in writing by such Investor
to the Company  specifically  for  inclusion in such  Registration  Statement or
Prospectus or amendment or supplement  thereto.  In no event shall the liability
of an Investor be greater in amount than the dollar  amount of the proceeds (net
of all expense paid by such  Investor in connection  with any claim  relating to
this Section 6 and the amount of any damages such  Investor has  otherwise  been
required to pay by reason of such untrue statement or omission) received by such
Investor  upon  the  sale  of  the  Registrable   Securities   included  in  the
Registration Statement giving rise to such indemnification obligation.

                           (c)  CONDUCT  OF  INDEMNIFICATION   PROCEEDINGS.  Any
person entitled to indemnification hereunder shall (i) give prompt notice to the
indemnifying  party of any claim with respect to which it seeks  indemnification
and (ii) permit such indemnifying party to assume the defense of such claim with
counsel  reasonably  satisfactory  to the indemnified  party;  PROVIDED that any
person  entitled  to  indemnification  hereunder  shall have the right to employ
separate  counsel and to participate in the defense of such claim,  but the fees
and expenses of such counsel  shall be at the expense of such person  unless (a)
the  indemnifying  party has  agreed to pay such  fees or  expenses,  or (b) the
indemnifying  party  shall have  failed to assume the  defense of such claim and
employ counsel  reasonably  satisfactory to such person or (c) in the reasonable
judgment  of any such  person,  based  upon  written  advice of its  counsel,  a
conflict of interest exists between such person and the indemnifying  party with
respect to such claims (in which case, if the person  notifies the  indemnifying
party in  writing  that such  person  elects to employ  separate  counsel at the
expense of the indemnifying  party,  the  indemnifying  party shall not have the
right to  assume  the  defense  of such  claim on behalf  of such  person);  and
PROVIDED,  FURTHER,  that the failure of any indemnified party to give notice as
provided  herein  shall not relieve the  indemnifying  party of its  obligations
hereunder,  except  to the  extent  that  such  failure  to  give  notice  shall
materially  adversely affect the  indemnifying  party in the defense of any such
claim or litigation.  It is understood that the indemnifying party shall not, in
connection with any proceeding in the same  jurisdiction,  be liable for fees or
expenses of more than one  separate  firm of  attorneys at any time for all such
indemnified  parties. No indemnifying party will, except with the consent of the
indemnified party, consent to entry of any judgment or enter into any settlement
that  does not  include  as an  unconditional  term  thereof  the  giving by the
claimant or plaintiff to such indemnified  party of a release from all liability
in respect of such claim or litigation.

                           (d)    CONTRIBUTION.    If   for   any   reason   the
indemnification  provided  for  in  the  preceding  paragraphs  (a)  and  (b) is
unavailable to an indemnified  party or insufficient to hold it harmless,  other
than  as  expressly  specified  therein,   then  the  indemnifying  party  shall
contribute to the amount paid or payable by the indemnified party as a result of
such loss,  claim,  damage or liability in such  proportion as is appropriate to
reflect the relative fault of the indemnified party and the indemnifying  party,
as well as any other  relevant  equitable  considerations.  No person  guilty of
fraudulent misrepresentation within the meaning of Section 11(f) of the 1933 Act
shall be entitled to contribution  from any person not guilty of such fraudulent
misrepresentation.  In no event shall the contribution obligation of a holder of
Registrable  Securities  be  greater  in amount  than the  dollar  amount of the
proceeds (net of all expenses  paid by such holder in connection  with any claim
relating  to this  Section  6 and the  amount of any  damages  such  holder  has
otherwise  been  required  to pay by reason of such  untrue  or  alleged  untrue
statement or omission or alleged  omission)  received by it upon the sale of the
Registrable Securities giving rise to such contribution obligation.

amended only by a writing signed by the Company and the Required Investors.  The
Company may take any action herein prohibited, or omit to perform any act herein
required to be  performed  by it, only if the Company  shall have  obtained  the

                           (c)  ASSIGNMENTS  AND  TRANSFERS  BY  INVESTORS.  The
provisions of this  Agreement  shall be binding upon and inure to the benefit of
the  Investors  and their  respective  successors  and assigns.  An Investor may
transfer  or  assign,  in  whole or from  time to time in  part,  to one or more
persons its rights  hereunder in  connection  with the  transfer of  Registrable
Securities by such Investor to such person, provided that such Investor complies
with all laws  applicable  thereto and provides  written notice of assignment to
the Company promptly after such assignment is effected.

                           (d)  ASSIGNMENTS  AND TRANSFERS BY THE COMPANY.  This
Agreement  may not be assigned by the Company  (whether by  operation  of law or
otherwise)  without  the  prior  written  consent  of  the  Required  Investors,
provided,  however,  that the  Company  may assign its rights and  delegate  its
duties hereunder to any surviving or successor  corporation in connection with a
merger or  consolidation  of the Company  with another  corporation,  or a sale,
transfer  or other  disposition  of all or  substantially  all of the  Company's
assets to another corporation, without the prior written consent of the Required
Investors, after notice duly given by the Company to each Investor.

                           (e)  BENEFITS  OF  THE   AGREEMENT.   The  terms  and
conditions of this  Agreement  shall inure to the benefit of and be binding upon
the respective permitted successors and assigns of the parties.  Nothing in this
Agreement,  express or implied,  is intended to confer upon any party other than
the  parties  hereto or their  respective  successors  and  assigns  any rights,
remedies,  obligations,  or  liabilities  under or by reason of this  Agreement,
except as expressly provided in this Agreement.

                           (f)  COUNTERPARTS;   FAXES.  This  Agreement  may  be
executed in two or more counterparts, each of which shall be deemed an original,
but all of which together shall  constitute  one and the same  instrument.  This
Agreement may also be executed via facsimile, which shall be deemed an original.

                           (g) TITLES AND  SUBTITLES.  The titles and  subtitles
used  in  this  Agreement  are  used  for  convenience  only  and  are not to be
considered in construing or interpreting this Agreement.

                           (h)  SEVERABILITY.  Any  provision of this  Agreement
that is  prohibited  or  unenforceable  in any  jurisdiction  shall,  as to such
jurisdiction,   be   ineffective   to  the   extent  of  such   prohibition   or
unenforceability  without invalidating the remaining provisions hereof but shall
be  interpreted  as if it were  written so as to be  enforceable  to the maximum
extent permitted by applicable law, and any such prohibition or unenforceability
in any jurisdiction shall not invalidate or render  unenforceable such provision
in any other  jurisdiction.  To the extent  permitted  by  applicable  law,  the
parties  hereby waive any provision of law which renders any  provisions  hereof
prohibited or unenforceable in any respect.

                           (i) FURTHER ASSURANCES. The parties shall execute and
deliver  all such  further  instruments  and  documents  and take all such other
actions as may reasonably be required to carry out the transactions contemplated
hereby and to evidence the fulfillment of the agreements herein contained.

                           (j) ENTIRE  AGREEMENT.  This Agreement is intended by
the  parties as a final  expression  of their  agreement  and  intended  to be a
complete and  exclusive  statement of the  agreement  and  understanding  of the
parties hereto in respect of the subject matter contained herein. This Agreement
supersedes  all prior  agreements  and  understandings  between the parties with
respect to such subject matter.

                           (k) GOVERNING LAW; CONSENT TO JURISDICTION; WAIVER OF
JURY TRIAL.  This  Agreement  shall be governed by, and  construed in accordance
with, the internal laws of the State of New York without regard to the choice of
law principles  thereof.  Each of the parties hereto irrevocably  submits to the
exclusive  jurisdiction  of the  courts of the State of New York  located in New
York County and the United States  District  Court for the Southern  District of
New York for the purpose of any suit, action, proceeding or judgment relating to
or arising  out of this  Agreement  and the  transactions  contemplated  hereby.
Service of process in connection with any such suit, action or proceeding may be
served on each party  hereto  anywhere  in the world by the same  methods as are
specified  for the giving of notices under this  Agreement.  Each of the parties
hereto  irrevocably  consents to the  jurisdiction of any such court in any such
suit,  action or proceeding and to the laying of venue in such court. Each party
hereto irrevocably waives any objection to the laying of venue of any such suit,
action or  proceeding  brought in such courts and  irrevocably  waives any claim
that any such  suit,  action or  proceeding  brought  in any such court has been
brought in an inconvenient forum. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT TO
REQUEST A TRIAL BY JURY IN ANY  LITIGATION  WITH RESPECT TO THIS  AGREEMENT  AND
REPRESENTS THAT COUNSEL HAS BEEN CONSULTED SPECIFICALLY AS TO THIS WAIVER.
