the  provisions of the  Securities  Act  applicable  thereto so as to permit the
Prospectus  forming  part  thereof to be current  and useable by  Investors  for
resales of the  Registrable  Securities for a period of three (3) years from the
date on which the  Registration  Statement  is first  declared  effective by the

upon the earlier of there ceasing to be any Registrable  Securities  outstanding
or when all the Registrable  Securities  covered by the  Registration  Statement
have been sold  pursuant  thereto in  accordance  with the plan of  distribution
provided  in  the  Prospectus,  transferred  pursuant  to  Rule  144  under  the
Securities Act or otherwise transferred in a manner that results in the delivery
of new securities not subject to transfer  restrictions under the Securities Act
(the  "Registration  Period") and (ii) take all lawful  action such that each of
(A) the  Registration  Statement  and any  amendment  thereto does not,  when it

request,  (ii) prepare and file in such jurisdictions such amendments (including
post-effective   amendments)   and   supplements  to  such   registrations   and
qualifications as may be necessary to maintain the effectiveness  thereof at all
times during the Registration  Period,  (iii) take all such other lawful actions
as may be necessary to maintain such  registrations and qualifications in effect

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

faith,  as  confidential,  proprietary  or  containing  any  material  nonpublic
information  shall be kept confidential by such Investors and any such attorney,
accountant or agent (pursuant to an appropriate confidentiality agreement in the
case of any such holder or agent),  unless such  disclosure  is made pursuant to
judicial  process in a court  proceeding  (after  first  giving  the  Company an
opportunity  promptly to seek a protective order or otherwise limit the scope of
the information  sought to be disclosed) or is required by law, or such records,
information or documents  become  available to the public generally or through a
third party not in violation of an accompanying  obligation of  confidentiality;
and  provided,  further,  that,  if the  foregoing  inspection  and  information

one firm of counsel  designed  by and on behalf of the  majority  in interest of
Investors and other parties.
          4. Obligations of the Investors
          In connection with the registration of the Registrable Securities, the
Investors shall have the following obligations:
          (a) It  shall  be a  condition  precedent  to the  obligations  of the
Company to complete the registration  pursuant to this Agreement with respect to
the  Registrable  Securities of a particular  Investor that such Investor  shall
furnish to the  Company  such  information  regarding
                                       6
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.  As least seven days prior to the first anticipated  filing
date of the  Registration  Statement,  the Company shall notify each Investor of
the  information  the Company  reasonably  requires from each such Investor (the
"Requested  Information") if such Investor elects to have any of its Registrable
Securities included in the Registration Statement. If at least two business days
prior to the anticipated  filing date the Company has not received the Requested
Information from an Investor (a "Non-Responsive Investor"), then the Company may
file the Registration Statement without including Registrable Securities of such
Non-Responsive  Investor and have no further  obligations to the  Non-Responsive
Investor;
          (b) Each  Investor by its  acceptance  of the  Registrable  Securities
agrees to cooperate  with the Company in  connection  with the  preparation  and
filing  of the  Registration  Statement  hereunder,  unless  such  Investor  has
notified  the  Company  in  writing  of  its  election  to  exclude  all  of its
Registrable Securities from the Registration Statement; and
          (c) Each  Investor  agrees  that,  upon receipt of any notice from the
Company of the  occurrence of any event of the kind described in Section 3(e) or
3(f), it shall immediately discontinue its disposition of Registrable Securities
pursuant to the  Registration  Statement  covering such  Registrable  Securities
until  such  Investor's  receipt of the  copies of the  supplemented  or amended
Prospectus contemplated by Section 3(e) and, if so directed by the Company, such
Investor shall deliver to the Company (at the expense of the Company) or destroy
(and deliver to the Company a  certificate  of  destruction)  all copies in such
Investor's  possession,  of the Prospectus covering such Registrable  Securities
current at the time of receipt of such notice.
          5. Right to Suspend Registration Statement
          The Company shall have the right for up to 120 days in any consecutive
360 period to suspend any  Registration  Statement in the event that the Company
determines,  in good faith,  that it is in the best  interest of the Company for
the Company to proceed with its own offering of equity  securities.  The Company
may so proceed by delivering  written notice of such intention to the Investors.
The Company may  exercise  the right to suspend a  Registration  Statement  only
twice in any 360-day period.
          6. Expenses of Registration
          All expenses,  other than  underwriting  discounts and  commissions or
similar  fees,   incurred  in   connection   with   registrations,   filings  or
qualifications  pursuant to Section 3, but including,  without  limitation,  all
registration,  listing,  and qualifications  fees,  printing and engraving fees,
accounting fees, and the fees and  disbursements of counsel for the Company (but
not of the Investors) shall be borne by the Company.
                                       7
          7. Indemnification and Contribution
          (a) The Company  shall  indemnify  and hold harmless each Investor and
each of their  respective  officers and  directors  and each person who controls
such Investor  within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act (each such person being sometimes hereinafter referred to
as an  "Indemnified  Person")  from and against any losses,  claims,  damages or
liabilities,  joint or  several,  to which  such  Indemnified  Person may become
subject under the Securities Act or otherwise,  insofar as such losses,  claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an  untrue  statement  or  alleged  untrue  statement  of a  material  fact
contained in any  Registration  Statement or an 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 arise out of or are based upon an
untrue statement or alleged untrue statement of a material fact contained in any
Prospectus  or an omission or alleged  omission to state therein a material fact
required to be stated  therein or necessary to make the statements  therein,  in
the light of the circumstances  under which they were made, not misleading;  and
the  Company  hereby  agrees  to  reimburse  such  Indemnified  Person  for  all
reasonable  legal  and  other  expenses  incurred  by  them in  connection  with
investigating  or defending  any such action or claim as and when such  expenses
are  incurred;  provided,  however,  that the Company shall not be liable to any
such  Indemnified  Person in any such  case to the  extent  that any such  loss,
claim,  damage  or  liability  arises  out of or is  based  upon  (i) an  untrue
statement  or  alleged  untrue  statement  made in, or an  omission  or  alleged
omission from, such Registration Statement or Prospectus in reliance upon and in
conformity with written information furnished to the Company by such Indemnified
Person  expressly  for use therein or (ii) in the case of the  occurrence  of an
event of the type specified in Section 3(e), the use by the  Indemnified  Person
of an outdated or  defective  Prospectus  after the Company has provided to such
Indemnified  Person an updated  Prospectus  correcting  the untrue  statement or
alleged  untrue  statement or omission or alleged  omission  giving rise to such
loss, claim, damage or liability.
          (b)  Indemnification  by the  Investors.  Each Investor  agrees,  as a
consequence  of  the  inclusion  of  any  of  its  Registrable  Securities  in a
Registration  Statement,  to (i) indemnify  and hold  harmless the Company,  its
directors  (including  any person who, with his or her consent,  is named in the
Registration  Statement as a director nominee of the Company),  its officers who
sign any  Registration  Statement  and each  person,  if any,  who  controls the
Company within the meaning of either Section 15 of the Securities Act or Section
20 of the Exchange Act,  against any losses,  claims,  damages or liabilities to
which the Company or such other persons may become subject, under the Securities
Act or otherwise,  insofar as such losses,  claims,  damages or liabilities  (or
actions in respect  thereof) arise out of or are based upon an untrue  statement
or alleged untrue  statement of a material fact  contained in such  Registration
Statement  or  Prospectus  or arise out of or are  based  upon the  omission  or
alleged  omission to state therein 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, in the case of the  Prospectus),  not misleading,  in each
case to the  extent,  but only to the  extent,  that such  untrue  statement  or
alleged  untrue  statement or omission or alleged  omission was made in reliance
upon and in conformity with written  information  furnished to the Company by or
on behalf of such holder or  underwriter  expressly  for use therein;  provided,
however,  that absent fraud, no Investor shall be liable under this Section 7(b)
for any amount in excess of the net proceeds paid to such Investor in respect of
                                       8
shares  sold by it,  and  (ii)  reimburse  the  Company  for any  legal or other
expenses  incurred by the Company in connection with  investigating or defending
any such action or claim as such expenses are incurred.
          (c) Notice of Claims,  etc.  Promptly after receipt by a party seeking
indemnification  pursuant to this Section 7 (an "Indemnified  Party") of written
notice of any  investigation,  claim,  proceeding  or other action in respect of
which  indemnification is being sought (each, a "Claim"),  the Indemnified Party
promptly  shall notify the party against whom  indemnification  pursuant to this
Section  7 is  being  sought  (the  "Indemnifying  Party")  of the  commencement
thereof;  but the omission to so notify the Indemnifying Party shall not relieve
it from any  liability  that it  otherwise  may have to the  Indemnified  Party,
except to the extent  that the  Indemnifying  Party is  actually  prejudiced  by
reason  of such  failure.  In  connection  with any  Claim as to which  both the
Indemnifying Party and the Indemnified Party are parties, the Indemnifying Party
shall be entitled to assume the defense thereof.  Notwithstanding the assumption
of the defense of any Claim by the  Indemnifying  Party,  the Indemnified  Party
shall have the right to employ  separate legal counsel and to participate in the
defense of such Claim,  and the  Indemnifying  Party  shall bear the  reasonable
fees,  out-of-pocket  costs and expenses of one such separate  legal counsel for
all  Indemnified  Parties  in  connection  with  any one  action  or  series  of
substantially related actions if (and only if): (x) the Indemnifying Party shall
have  agreed in  writing  to pay such fees,  costs and  expenses,  (y) the named
parties to any such action  (including any impleaded  parties)  include both the
Indemnified  Party and the  Indemnifying  Party and the Indemnified  Party shall
have been advised by such counsel in writing that there may be one or more legal
defenses  available to the Indemnifying party different from or in conflict with
any legal  defenses  which may be available to the  Indemnified  Party (in which
case the  Indemnifying  party  shall not have the right to assume the defense of
such action on behalf of the Indemnified  party, or (z) the  Indemnifying  Party
shall  have  failed to  employ  legal  counsel  reasonably  satisfactory  to the
Indemnified  Party  within a  reasonable  period  of time  after  notice  of the
commencement  of such Claim.  If the  Indemnified  Party employs  separate legal
counsel in  circumstances  other than as  described  in clauses  (x), (y) or (z)
above,  the fees,  costs  and  expenses  of such  legal  counsel  shall be borne
exclusively by the Indemnified Party. Except as provided above, the Indemnifying
Party  shall not,  in  connection  with any Claim in the same  jurisdiction,  be
liable  for the fees and  expenses  of more  than  one firm of  counsel  for the
Indemnified  Party (together with  appropriate  local counsel).  The Indemnified
Party shall not,  without the prior written  consent of the  Indemnifying  Party
(which  consent shall not  unreasonably  be withheld),  settle or compromise any
Claim or  consent  to the  entry  of any  judgment  that  does  not  include  an
unconditional  release  of the  Indemnifying  Party  from all  liabilities  with
respect to such Claim or judgment.
          (d) Contribution.  If the indemnification provided for in this Section
7 is unavailable to or insufficient to hold harmless an Indemnified Person under
subsection  (a) or (b)  above in  respect  of any  losses,  claims,  damages  or
liabilities  (or actions in respect  thereof)  referred  to  therein,  then each
Indemnifying  Party  shall  contribute  to the  amount  paid or  payable by such
Indemnified Party as a result of such losses, claims, damages or liabilities (or
actions in respect  thereof) in such proportion as is appropriate to reflect the
relative fault of the Indemnifying Party and the Indemnified Party in connection
with the statements or omissions
                                       9
which resulted in such losses,  claims,  damages or  liabilities  (or actions in
respect thereof),  as well as any other relevant equitable  considerations.  The
relative  fault  of such  Indemnifying  Party  and  Indemnified  Party  shall be
determined by reference  to, among other  things,  whether the untrue or alleged
untrue  statement of a material fact or omission or alleged  omission to state a
material fact relates to information  supplied by such Indemnifying  Party or by
such Indemnified Party, and the parties' relative intent,  knowledge,  access to
information  and  opportunity  to correct or prevent such statement or omission.
The parties hereto agree that it would not be just and equitable if contribution
pursuant to this Section 7(d) were  determined by pro rata  allocation  (even if
the  Investors  were  treated as one entity  for such  purpose)  or by any other
method of allocation which does not take account of the equitable considerations
referred to in this Section 7(d).  The amount paid or payable by an  Indemnified
Party as a result of the losses,  claims,  damages or liabilities (or actions in
respect thereof) referred to above shall be deemed to include any legal or other
fees or expenses  reasonably  incurred by such  Indemnified  Party in connection
with  investigating  or defending any such action or claim.  No person guilty of
fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f)  of the
Securities  Act) shall be entitled to  contribution  from any person who was not
guilty of such fraudulent misrepresentation.
          (e) Notwithstanding any other provision of this Section 7, in no event
shall any Investor be required to  undertake  liability to any person under this
Section 7 for any amounts in excess of the dollar  amount of the  proceeds to be
received  by  such  Investor  from  the  sale  of  such  Investor's  Registrable
Securities  pursuant to any Registration  Statement under which such Registrable
Securities are to be registered under the Securities Act.
          (f) The  obligations  of the Company  under this Section 7 shall be in
addition  to  any  liability  which  the  Company  may  otherwise  have  to  any
Indemnified  Person and the  obligations  of any  Indemnified  Person under this
Section 7 shall be in addition to any liability  which such  Indemnified  Person
may otherwise have to the Company.  The remedies  provided in this Section 7 are
not exclusive and shall not limit any rights or remedies  which may otherwise be
available to an indemnified party at law or in equity.
          8. Rule 144
          With a view to making  available to the Investors the benefits of Rule
144 under the  Securities  Act or any other  similar rule or  regulation  of the
Commission  that may at any time permit the Investors to sell  securities of the
Company to the public without  registration  ("Rule 144"), the Company agrees to
use its reasonable best efforts to:
          (a) comply with the provisions of paragraph (c) (1) of Rule 144; and
          (b) file with the  Commission in a timely manner all reports and other
documents  required to be filed by the  Company  pursuant to Section 13 or 15(d)
under the  Exchange  Act;  and,  if at any time it is not  required to file such
reports but in the past had been required to or did file such reports,  it will,
upon the request of any Investor,  make available other  information as required
by, and so long as  necessary  to permit  sales of, its  Registrable  Securities
pursuant to Rule 144.
                                       10
          9. Assignment
          The  rights  to  have  the  Company  register  Registrable  Securities
pursuant to this Agreement shall be  automatically  assigned by the Investors to
any permitted  transferee of all or a portion (which portion shall exceed 10% of
the  Registrable  Securities  on an  as-converted  basis)  of  such  Registrable
Securities  (or  all  or a  portion  (which  portion  shall  exceed  10%  of the
Registrable Securities on an as-converted basis) of any Debentures or Warrant of
the Company which is convertible into such securities) only if: (a) the Investor
agrees in writing with the  transferee or assignee to assign such rights,  and a
copy of such  agreement  is furnished  to the Company  within a reasonable  time
after such assignment, (b) the Company is, within ten (10) Business Days of such
transfer  or  assignment,  furnished  with  written  notice  of (i) the name and
address of such  transferee or assignee and (ii) the securities  with respect to
which  such  registration   rights  are  being  transferred  or  assigned,   (c)
immediately following such transfer or assignment, the securities so transferred
or assigned to the transferee or assignee constitute Restricted Securities,  and
(d) at or before the time the Company  receives the written notice  contemplated
by clause (b) of this sentence the transferee or assignee agrees in writing with
the Company to be bound by all of the provisions contained herein.
          10. Amendment and Waiver
          Any  provision  of this  Agreement  may be amended and the  observance
thereof may be waived (either  generally or in a particular  instance and either
retroactively  or  prospectively),  only with the written consent of the Company
and Investors who hold a majority-in-interest of the Registrable Securities. Any
amendment or waiver effected in accordance with this Section 10 shall be binding
upon each Investor and the Company.
          11. Changes in Common Stock
          If, and as often as,  there are any changes in the Common Stock by way
of stock split, stock dividend,  reverse split, combination or reclassification,
or through merger, consolidation,  reorganization or recapitalization, or by any
other means,  appropriate  adjustment shall be made in the provisions hereof, as
may be required, so that the rights and privileges granted hereby shall continue
with respect to the Common Stock as so changed.
          12. Miscellaneous
          (a) A person or entity  shall be deemed to be a holder of  Registrable
Securities  whenever  such  person or entity  owns of  record  such  Registrable
Securities.  If  the  Company  receives  conflicting  instructions,  notices  or
elections  from  two or more  persons  or  entities  with  respect  to the  same
Registrable  Securities,  the Company shall act upon the basis of  instructions,
notice  or  election  received  from the  registered  owner of such  Registrable
Securities.
          (b) If,  after the date hereof and prior to the  Commission  declaring
the Registration  Statement to be filed pursuant to Section 2(a) effective under
the  Securities  Act, the Company grants to any Person any  registration  rights
with respect to any Company  securities  which are more  favorable to such other
Person than those provided in this Agreement,  then the Company
                                       11
forthwith  shall grant (by means of an amendment to this Agreement or otherwise)
identical registration rights to all Investors hereunder.
          (c) Except as may be otherwise  provided  herein,  any notice or other
communication  or delivery  required or permitted  hereunder shall be in writing
and shall be delivered personally or sent by certified mail, postage prepaid, or
by a nationally  recognized overnight courier service, and shall be deemed given
when so delivered  personally or by overnight  courier  service,  or, if mailed,
three days after the date of deposit in the United States mails, as follows:

     shall have provided in writing to the Company.
The  Company,  the Initial  Investor or any  Investor  may change the  foregoing
address by notice given pursuant to this Section 12(c).
          (d)  Failure of any party to exercise  any right or remedy  under this
Agreement or otherwise,  or delay by a party in exercising such right or remedy,
shall not operate as a waiver thereof.
          (e) This Agreement  shall be governed by and interpreted in accordance
with the laws of the  State of New York.  Each of the  parties  consents  to the
jurisdiction  of the federal  courts whose  districts  encompass any part of the
City of New York or the state  courts of the  State of New York  sitting  in the

hereby waives,  to the maximum extent permitted by law, any objection  including
any  objection  based on  forum  non  conveniens,  to the  bringing  of any such
proceeding in such jurisdictions.
          (f) The remedies  provided in this  Agreement are  cumulative  and not
exclusive of any remedies provided by law. If any term,  provision,  covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be
invalid, illegal, void or unenforceable, the remainder of the terms, provisions,
covenants  and  restrictions  set forth  herein  shall  remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto shall use their best efforts to find and employ an  alternative  means to
achieve the same or substantially  the same result as that  contemplated by such
term, provision,  covenant or restriction.  It is hereby stipulated and declared
to be the  intention of the parties that they would have  executed the remaining
terms, provisions, covenants and restrictions without including any of such that
may be hereafter declared invalid, illegal, void or unenforceable.
          (g) The Company shall not enter into any agreement with respect to its

Registrable  Securities  in this  Agreement  or  otherwise  conflicts  with  the
provisions hereof.
          (h) This Agreement,  the Securities Purchase Agreement, the Debentures
and the Warrants  constitute the entire  agreement among the parties hereto with
respect to the  subject  matter  hereof.  There are no  restrictions,  promises,
warranties  or  undertakings,  other than those set forth or referred to herein.
This  Agreement,  the  Securities  Purchase  Agreement,  the  Debentures and the
Warrants  supersede  all prior  agreements  and  undertakings  among the parties
