Transaction  Documents (whether brought against a party hereto or its respective
affiliates,  directors,  officers,  shareholders,  employees or agents) shall be
commenced  in the  state and  federal  courts  sitting  in the City of New York,
Borough  of  Manhattan  (the  "New  York  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 suit,  action or proceeding,  any claim
that it is not personally subject to the jurisdiction of any such court, or such
New York Courts are improper or  inconvenient  venue for such  proceeding.  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 via registered or certified mail or overnight delivery (with evidence of
delivery)  to such party at the  address in effect for  notices to it under this
Debenture  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.
Each party hereto hereby irrevocably  waives, to the fullest extent permitted by
applicable  law,  any and all  right to trial  by jury in any  legal  proceeding
arising out of or relating to this  Debenture or the  transactions  contemplated
hereby.  If either party shall  commence an action or  proceeding to enforce any
provisions  of this  Debenture,  then the  prevailing  party in such  action  or
proceeding shall be reimbursed by the other party for its reasonable  attorneys'
fees and other costs and expenses incurred with the  investigation,  preparation
and prosecution of such action or proceeding.

            (f)  Waiver.  Any waiver by the Company or the Holder of a breach of
any  provision  of this  Debenture  shall not operate as or be construed to be a
waiver  of any  other  breach of such  provision  or of any  breach of any other
provision of this Debenture.  The failure of the Company or the Holder to insist
upon strict  adherence to any term of this  Debenture  on one or more  occasions
shall not be  considered a waiver or deprive that party of the right  thereafter
to  insist  upon  strict  adherence  to  that  term  or any  other  term of this
Debenture. Any waiver must be in writing.

            (g)  Severability.  If any  provision of this  Debenture is invalid,
illegal or unenforceable,  the balance of this Debenture shall remain in effect,
and if any provision is  inapplicable  to any person or  circumstance,  it shall
nevertheless  remain  applicable to all other persons and  circumstances.  If it
shall be found that any interest or other amount  deemed  interest due hereunder
violates  applicable laws governing  usury,  the applicable rate of interest due
hereunder shall  automatically be lowered to equal the maximum permitted rate of
interest.  The Company covenants (to the extent that it may lawfully do so) that
it shall not at any time insist upon,  plead, or in any manner  whatsoever claim
or take the benefit or advantage  of, any stay,  extension or usury law or other
law which would  prohibit or forgive the Company  from paying all or any portion
of the  principal  of or  interest on this  Debenture  as  contemplated  herein,
wherever enacted, now or at any time hereafter in force, or which may affect the
covenants or the performance of this  indenture,  and the Company (to the extent
it may lawfully do so) hereby  expressly waives all benefits or advantage of any
such law,  and  covenants  that it will not, by resort to any such law,  hinder,
delay or impeded the  execution of any power herein  granted to the Holder,  but
will  suffer and permit  the  execution  of every such as though no such law has
been enacted.

            (h) Next  Business  Day.  Whenever  any payment or other  obligation
hereunder shall be due on a day other than a Business Day, such payment shall be
made on the next succeeding Business Day.

            (i)  Headings.  The headings  contained  herein are for  convenience
only,  do not  constitute  a part of this  Debenture  and shall not be deemed to
limit or affect any of the provisions hereof.

            (j) Usury.  To the extent it may lawfully do so, the Company  hereby
agrees not to insist upon or plead or in any manner  whatsoever  claim, and will
resist any and all efforts to be compelled to take the benefit or advantage  of,
usury  laws  wherever  enacted,  now or at  any  time  hereafter  in  force,  in
connection  with any  claim,  action or  proceeding  that may be  brought by any
Purchaser  in  order to  enforce  any  right or  remedy  under  any  Transaction
Document.  Notwithstanding  any  provision  to  the  contrary  contained  in any
Transaction  Document,  it is  expressly  agreed  and  provided  that the  total
liability of the Company  under the  Transaction  Documents  for payments in the
nature of interest shall not exceed the Maximum Rate, and,  without limiting the
foregoing,  in no event shall any rate of interest or default interest,  or both
of them,  when aggregated with any other sums in the nature of interest that the
Company may be  obligated  to pay under the  Transaction  Documents  exceed such
Maximum Rate. It is agreed that if the maximum contract rate of interest allowed
by law and applicable to the Transaction  Documents is increased or decreased by
statute or any official  governmental  action subsequent to the date hereof, the
new maximum  contract  rate of interest  allowed by law will be the Maximum Rate
applicable to the Transaction Documents from the effective date of such increase
or decrease forward,  unless such application is precluded by applicable law. If
under any  circumstances  whatsoever,  interest in excess of the Maximum Rate is
paid by the  Company to any  Purchaser  with  respect to  indebtedness,  if any,
evidenced  by the  Transaction  Documents,  such excess shall be applied by such
Purchaser  to the  unpaid  principal  balance  of any  such  indebtedness  or be
refunded  to the  Company,  the  manner of  handling  such  excess to be at such
Purchaser's election in the event any principal amount remains outstanding.

            (k) Assumption.  Any successor to the Company or surviving entity in
a Fundamental  Transaction or any merger or consolidation of the Company with or
into  another  Person  ("Merger")  shall  (i)  assume  in  writing  all  of  the
obligations  of the  Company  under  this  Debenture  and the other  Transaction
Documents pursuant to written  agreements in form and substance  satisfactory to
the Holder (such approval not to be  unreasonably  withheld or delayed) prior to
such  Fundamental  Transaction  or Merger  and (ii) to issue to the Holder a new
debenture  of  such  successor   entity   evidenced  by  a  written   instrument
substantially  similar  in form  and  substance  to this  Debenture,  including,
without  limitation,  having a principal  amount and interest  rate equal to the
principal  amounts and the interest rates of the  Debentures  held by the Holder
and having similar  ranking to this  Debenture,  and  satisfactory to the Holder
(any such approval not to be unreasonably  withheld or delayed).  The provisions
of this Section 7(k) shall apply similarly and equally to successive Fundamental
Transactions or Merger and shall be applied without regard to any limitations of
this Debenture.

            (l) Waivers and Amendments.  With the written consent of the holders
of at least 75% of the principal  amount of all  outstanding  Debentures  (which
holders must include all Qualified  Purchasers),  the obligations of the Company
and the  rights of the  Holder  under  this  Debenture  may be amended or waived
(either  generally  or  in  a  particular  instance,   either  retroactively  or
prospectively, and either for a specified period of time or indefinitely).

      IN WITNESS  WHEREOF,  the  Company has caused  this  Debenture  to be duly
executed by a duly authorized officer as of the date first above indicated.

covered by such registration  statement (provided that nothing in this Agreement
shall be deemed to  preclude  the  Company  from  withdrawing  any  registration
statement at any time, before it has been declared  effective by the SEC) as may

applicable  Registrable  Securities for the Effectiveness Period and prepare and
file with the SEC such additional  registration  statements in order to register
for resale under the Securities Act all of the Registrable  Securities;  respond
as promptly as  reasonably  possible to any comments  received from the SEC with

registration  statement during the applicable  period in accordance  (subject to
the terms of this  Agreement)  with the intended  methods of  disposition by the
Holders  thereof set forth in such  Registration  Statement  as so amended or in
such Prospectus as so supplemented.

            (b) Furnish,  without charge,  to the Holders such numbers of copies
of a prospectus,  including each preliminary prospectus,  in conformity with the
requirements  of the  Securities  Act,  and  such  other  documents  as they may
reasonably  request  in order  to  facilitate  the  disposition  of  Registrable
Securities  owned by them.  The Holders shall not be entitled to use any selling
materials other than a prospectus and such other materials as may be approved by
the Company, which approval shall not be unreasonably withheld.

            (c) Use its commercially  reasonable efforts to register and qualify
the  securities  covered  by  such  registration   statement  under  such  other
securities  or Blue  Sky  laws of such  jurisdictions  as  shall  be  reasonably

registration  statement  at any  time  when a  prospectus  relating  thereto  is
required to be delivered  under the Securities Act or the happening of any event
as a result of which the prospectus included in such 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  not  misleading  in the  light  of the  circumstances  then
existing.

reasonable manner, financial and other records,  documents and properties of the
Company that are  pertinent  to the conduct of due  diligence  customary  for an
underwritten  offering,  and cause the officers,  directors and employees of the
Company   to  supply  all   information   reasonably   requested   by  any  such

registration  statement,  a customary "10b-5" opinion of independent counsel (an

statement and the closing of any sale of Registrable Securities covered thereby,
the  representations and warranties of the Company contained in any underwriting
agreement, securities sales agreement or other similar agreement, including this
Agreement,  relating to disclosure  cease to be true and correct in all material
respects  or if the  Company  receives  any  notification  with  respect  to the
suspension of the  qualification  of the Registrable  Securities for sale in any
jurisdiction  or the initiation of any  proceeding for such purpose,  (E) of the
happening of any event during the period the registration statement is effective

untrue  statement of a material  fact or omits to state a material fact required
to be stated therein or necessary to make statements  therein not misleading (in
the case of a prospectus,  in light of circumstances under which they were made)
and (F) of any  determination by the Company that a post-effective  amendment to
the  registration  statement would be  appropriate.  The Holders hereby agree to
suspend, and to cause any managing underwriter to suspend, use of the prospectus
contained in a  registration  statement upon receipt of such notice under clause
(C),  (E) or (F) above  until,  in the case of clause  (C),  such stop  order is
removed or  rescinded  or, in the case of clauses  (E) and (F),  the Company has
amended or supplemented such prospectus to correct such misstatement or omission
or otherwise.

the Company shall  promptly  prepare and furnish to each selling Holder and each
underwriter,  if any, a reasonable number of copies of a prospectus supplemented
or  amended  so  that,  as  thereafter  delivered  to  the  purchasers  of  such
Registrable Securities, such prospectus shall not include an 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 not misleading.

                        (ix)  make   reasonably   available  its  employees  and
personnel and otherwise provide reasonable assistance to the underwriters in the
marketing of Registrable Securities in any underwritten offering;

<PAGE>

                        (x) cooperate with the sellers of Registrable Securities
and the managing  underwriter,  if any, to facilitate the timely preparation and
delivery of certificates  not bearing any restrictive  legends  representing the
Registrable  Securities to be sold, and cause such Registrable  Securities to be
issued in such denominations and registered in such names in accordance with the
underwriting  agreement  prior  to any  sale of  Registrable  Securities  to the
underwriters  or,  if not an  underwritten  offering,  in  accordance  with  the
instructions  of the sellers of  Registrable  Securities at least three business
days prior to any sale of Registrable Securities;

                        (xi) If NASDR Rule 2710  requires any  broker-dealer  to

an Issuer Filing with the NASDR, Inc. Corporate Financing Department pursuant to
NASDR Rule  2710(b)(10)(A)(i),  (ii)  respond  within five  Trading  Days to any

            1.5 Indemnification.

                  (a) The  Company  will  indemnify  and  hold  harmless  to the
fullest extent  permitted by law each Holder of Registrable  Securities and each
of its  officers,  directors  and  partners,  and each person  controlling  such
Holder, with respect to which such registration, qualification or compliance has
been effected pursuant to this Agreement, and each underwriter, if any, and each
person who controls any  underwriter of the  Registrable  Securities  held by or
issuable  to such  Holder,  against all claims,  losses,  expenses,  damages and
liabilities (or actions in respect  thereto)  arising out of or based on (i) any
untrue  statement (or alleged untrue  statement) of a material fact contained in
any registration statement under which such securities were registered under the
Securities  Act or 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;  (ii) any untrue  statement (or alleged untrue  statement) of a
material fact contained in any preliminary or final prospectus,  or based on any
omission (or alleged  omission) to state  therein a material fact required to be
stated  therein or  necessary  to make the  statement  therein,  in light of the
circumstances  under  which  they were  made,  or not  misleading,  or (iii) any
violation  or alleged  violation  by the  Company  of the  Securities  Act,  the
Exchange Act or any state  securities  law applicable to the Company or any rule
or regulation promulgated under the Securities Act, the Exchange Act or any such
state  law and  relating  to action  or  inaction  required  of the  Company  in
connection with any such  registration,  qualification  of compliance,  and will
reimburse each such Holder,  each of its officers,  directors and partners,  and
each person  controlling such Holder,  each such underwriter and each person who
controls any such  underwriter,  within five days from the date incurred for any
reasonable   legal  and  any  other   expenses   incurred  in  connection   with
investigating,  defending or settling any such claim, loss, damage, liability or
action;  provided,  however,  that the  indemnity  agreement  contained  in this
subsection  1.5(a)  shall not apply to amounts  paid in  settlement  of any such
claim, loss, damage, liability, or action if such settlement is effected without
the consent of the Company (which consent shall not be  unreasonably  withheld);
and  provided  further,  that the Company will not be liable in any such case to
the extent that any such claim,  loss,  damage or liability  arises out of or is
based on any  untrue  statement  or  omission  based  upon  written  information
furnished to the Company in writing by such Holder or  underwriter  specifically
for use therein;  and provided  further,  however,  that the Company will not be
liable in any such  case to the  extent  that any such  claim,  loss,  damage or
liability  arises directly out of or is based primarily upon an untrue statement
or  omission  made in any  preliminary  or final  prospectus  if (i) such Holder
failed  to  send  or  deliver  a copy  of the  final  prospectus  or  prospectus
supplement with or prior to the delivery of written  confirmation of the sale of
the  Registrable   Securities  and  (ii)  the  final  prospectus  or  prospectus
supplement would have corrected such untrue statement or omission, provided that
the Company had  previously  notified such Holder in writing that the prospectus
is outdated or defective.  The Company shall notify the Holders  promptly of the
institution, threat or assertion of any Proceeding arising from or in connection
with the  transactions  contemplated  by this  Agreement of which the Company is
aware.

                  (b) Each Holder will,  if  Registrable  Securities  held by or
issuable  to such  Holder  are  included  in the  securities  as to  which  such
registration,  qualification or compliance is being effected,  severally and not
jointly,  indemnify and hold harmless to the fullest extent permitted by law the
Company,  each of its directors and officers,  each underwriter,  if any, of the
Company's securities covered by such a registration  statement,  each person who
controls the Company  within the meaning of the  Securities  Act, and each other
such  Holder,  each of its  officers,  directors  and  partners  and each person
controlling  such  Holder,  against all claims,  losses,  expenses,  damages and
liabilities  (or  actions in  respect  thereof)  arising  out of or based on any
untrue  statement (or alleged untrue  statement) of a material fact contained in
any such registration  statement or final  prospectus,  or based on any omission
(or alleged  omission) to state  therein a material  fact  required to be stated
therein or necessary to make the statements  therein 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) is made in such registration
statement or  prospectus in reliance  upon and in  conformity  with  information
furnished to the Company in writing by such Holder specifically for use therein,
and  will  reimburse  the  Company,  such  Holders,  such  directors,  officers,
partners, persons or underwriters for any reasonable legal or any other expenses
incurred in connection with investigating, defending or settling any such claim,
loss,  damage,  liability or action, in each case to the extent, but only to the
extent, that such untrue statement (or alleged untrue statement) or omission (or
alleged  omission)  is made in such  registration  statement  or  prospectus  in
reliance upon and in  conformity  with  information  furnished to the Company by
such Holder specifically for use therein; provided,  however, that the indemnity
agreement contained in this subsection 1.5(b) shall not apply to amounts paid in
settlement  of any  such  claim,  loss,  damage,  liability  or  action  if such
settlement is effected  without the consent of the Holder  (which  consent shall
not be unreasonably  withheld);  and provided further, that the total amount for
which any Holder shall be liable under this  subsection  1.5(b) shall not in any
event  exceed  the  net  proceeds  received  by such  Holder  from  the  sale of
Registrable  Securities held by such Holder in such registration  giving rise to
such indemnification obligation; and provided further, that a Holder will not be
liable in any such  case to the  extent  that any such  claim,  loss,  damage or
liability  arises out of or is based on any untrue  statement or omission  based
upon written  information  furnished to the Holder by the Company or underwriter
specifically for use therein.

<PAGE>

                  (c)  Each  party  entitled  to   indemnification   under  this
subsection 1.5 (the "Indemnified Party") shall give notice to the party required
to  provide  indemnification  (the  "Indemnifying  Party")  promptly  after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought,  and shall  permit the  Indemnifying  Party to assume the defense of any
such claim or any litigation resulting therefrom;  provided that counsel for the
Indemnifying  Party,  who shall conduct the defense of such claim or litigation,
shall  be  approved  by the  Indemnified  Party  (whose  approval  shall  not be
unreasonably  withheld),  and the  Indemnified  Party  may  participate  in such
defense at such party's expense;  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  such
failure resulted in material  prejudice to the Indemnifying  Party; and provided
further,  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.  No Indemnifying  Party, in the
defense of any such claim or litigation,  shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement
which  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 to such claim or litigation.

                  (d) If for any reason the foregoing  indemnity is  unavailable
or is insufficient to hold harmless an indemnified  party under  subsection 1.5,
then each  Indemnifying  Party shall contribute to the amount paid or payable by
such  Indemnified  Party  as a result  of any  claim  in such  proportion  as is
appropriate to reflect the relative fault of the Indemnifying  Party, on the one
hand,  and the  Indemnified  Party,  on the other  hand,  with  respect  to such
offering of securities.  The relative fault shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the  omission or alleged  omission to state a material  fact  relates to
information  supplied by the Indemnifying Party or the Indemnified Party and the
parties'  relative intent,  knowledge,  access to information and opportunity to
correct  or  prevent  such  untrue  statement  or  omission.  If,  however,  the
allocation  provided  in the  second  preceding  sentence  is not  permitted  by
applicable law, then each Indemnifying Party shall contribute to the amount paid
or payable by such  Indemnified  Party in such  proportion as is  appropriate to
reflect not only such relative  faults,  but also any other  relevant  equitable
considerations. The parties hereto agree that it would not be just and equitable
if contributions pursuant to this subsection 1.5(d) were to be determined by pro
rata  allocation or by any other method of  allocation  which does not take into
account the equitable  considerations  referred to in the preceding sentences of
this subsection 1.5(d). The amount paid or payable in respect of any claim shall
be deemed to include  any legal or other  expenses  reasonably  incurred by such
Indemnified Party in connection with  investigating or defending any such 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.  Notwithstanding
anything in this subsection 1.5 to the contrary,  no  Indemnifying  Party (other
than the  Company)  shall be  required  pursuant  to this  subsection  1.5(d) to
contribute  any  amount  in  excess  of  the  net  proceeds   received  by  such
Indemnifying  Party from the sale of  Registrable  Securities in the offering to
which the losses,  claims,  damages or  liabilities of the  Indemnified  Parties
relate,  less  the  amount  of any  indemnification  payment  made  pursuant  to
subsection 1.5.

<PAGE>

                  (e) The indemnity and contribution agreements contained herein
shall be in  addition to any other  rights to  indemnification  or  contribution
which any  Indemnified  Party may have  pursuant  to law or  contract  and shall
remain  operative and in full force and effect  regardless of any  investigation
made or omitted by, or on behalf of, any Indemnified Party and shall survive the
transfer of the Registrable Securities by any such party.

                  (f) Notwithstanding  any provision herein to the contrary,  no
party shall be entitled to  indemnification  or contribution with respect to any
claims, losses, expenses, damages or liabilities (or actions in respect thereto)
caused by such party's willful misconduct or gross negligence.

            1.6  Information  by Holder.  The Company may require  each  selling
Holder to  furnish  to the  Company a  certified  statement  as to the number of
shares of Common Stock beneficially owned by such Holder and, if required by the
SEC, the person thereof that has voting and dispositive control over the Shares.

            1.7 Rule 144 Reporting.  With a view to making  available to Holders
the benefits of certain  rules and  regulations  of the SEC which may permit the
sale of the  Registrable  Securities  to the public  without  registration,  the
Company agrees at all times to:

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

                  (b) file with the SEC in a timely manner all reports and other
documents  required of the Company under the Securities Act and the Exchange Act
(at any time after it has become subject to such reporting requirements); and

                  (c) so long as a Holder owns any  Registrable  Securities,  to
furnish to such Holder  forthwith  upon  receipt of a written  request a written
statement by the Company as to its compliance with the reporting requirements of
said Rule 144 and of the Securities Act and the Exchange Act, a copy of the most
recent  annual or quarterly  report of the Company,  and such other  reports and
documents  so filed by the  Company  as the  Holder  may  reasonably  request in
complying with any rule or regulation of the SEC allowing the Holder to sell any
such securities without registration.

            1.8 Transfer of  Registration  Rights.  Each Holder may assign their
respective  rights hereunder in the manner and to the Persons as permitted under
the Purchase Agreement

            1.9 [RESERVED].

            1.10 Delay of Registration.  No Holder shall have any rights to take
any actions to restrain,  enjoin,  or otherwise  delay any  registration  as the
result of any controversy that might arise with respect to the interpretation or
implementation of this Section 1.

            1.11 Termination of Registration Rights. No Holder shall be entitled
to  exercise  any right  provided  for in this  Section  1 at any time,  and the
obligations of the Company to a Holder under this Section 1 shall terminate with
respect  to  such  Holder,  when  all  Registrable  Securities  covered  by such
Registration Statement have been sold or may be sold without volume restrictions
pursuant to Rule 144(k) as determined by the counsel to the Company  pursuant to
a written  opinion  letter  to such  effect,  addressed  and  acceptable  to the
Company's transfer agent and the affected Holders (the "Effectiveness Period").

      2. General.

            2.1 Waivers and  Amendments.  With the written consent of the record
holders of at least a 30% of the Registrable Securities,  the obligations of the
Company and the rights of the parties under this Agreement may be waived (either
generally or in a particular  instance,  either  retroactively or prospectively,
and either for a specified  period of time or  indefinitely),  and with the same
consent the Company,  when  authorized  by resolution of its Board of Directors,
may  enter  into a  supplementary  agreement  for  the  purpose  of  adding  any
provisions to or changing in any manner or eliminating  any of the provisions of
this  Agreement;  provided,  however,  that no such  modification,  amendment or
waiver shall reduce the aforesaid  percentage of Registrable  Securities without
the  consent  of all of the  Holders  of the  Registrable  Securities.  Upon the
effectuation   of  each  such  waiver,   consent,   agreement  of  amendment  or
modification,  the Company  shall  promptly give written  notice  thereof to the
record holders of the Registrable  Securities who have not previously  consented
thereto in  writing.  This  Agreement  or any  provision  hereof may be changed,
waived,  discharged or terminated  only by a statement in writing  signed by the
party against which enforcement of the change, waiver,  discharge or termination
is sought,  except to the extent  provided in this  subsection 2.1. In the event
the Company  enters  into a  Subsequent  Financing,  and upon the request of the
Company,  each Purchaser shall execute the registration rights agreement entered
into by the investors in such  Subsequent  Financing (on a pari passu basis with
such investors) and this Agreement shall be terminated.

            2.2 Governing Law/Consent to Jurisdiction.  All questions concerning
the construction,  validity,  enforcement,  interpretation of, and venue for any
dispute  under this  Agreement  shall be determined  with the  provisions of the
Purchase Agreement.

            2.3 Successors and Assigns.  Except as otherwise  expressly provided
herein,  the  provisions  hereof  shall  inure to the benefit of, and be binding
upon,  the  successors,  assigns,  heirs,  executors and  administrators  of the
parties hereto.

            2.4 Entire Agreement.  Except as set forth below, this Agreement and
the other documents  delivered  pursuant  hereto  constitute the full and entire
understanding  and  agreement  between the parties  with regard to the  subjects
hereof and thereof,  and this  Agreement  shall  supersede  and cancel all prior
agreements between the parties hereto with regard to the subject matter hereof.

            2.5  Notices,  etc. Any and all notices or other  communications  or
deliveries  required or permitted to be provided hereunder shall be delivered as
set forth in the Purchase Agreement

            2.6  Severability.  In case any provision of this Agreement shall be
invalid, illegal, or unenforceable, the validity, legality and enforceability of
the  remaining  provisions  of this  Agreement  or any  provision  of the  other
Agreement s shall not in any way be affected or impaired thereby.

                                       11
<PAGE>

            2.7 Titles and Subtitles. The titles of the sections and subsections
of this  Agreement  are for  convenience  of  reference  only  and are not to be
considered in construing this Agreement.

            2.8  Counterparts.  This  Agreement may be executed in any number of
counterparts,  each of which  shall be an  original,  but all of which  together
shall constitute one instrument. In the event that any signature is delivered by
facsimile  transmission,  such signature shall create a valid binding obligation
of the party  executing (or on whose behalf such signature is executed) the same
with the same force and effect as if such facsimile  signature were the original
thereof.

            2.9  Independent  Nature of Holders'  Obligations  and  Rights.  The
obligations  of each  Holder  hereunder  are  several  and not  joint  with  the
obligations of any other Holder hereunder, and no Holder shall be responsible in
any way for the  performance of the  obligations of any other Holder  hereunder.
Nothing contained herein or in any other agreement or document  delivered at any
closing, and no action taken by any Holder pursuant hereto or thereto,  shall be
deemed to  constitute  the Holders as a  partnership,  an  association,  a joint
venture or any other kind of entity,  or create a  presumption  that the Holders
are in any way  acting  in  concert  with  respect  to such  obligations  or the
transactions  contemplated by this  Agreement.  Each Holder shall be entitled to
protect and enforce its rights,  including without limitation the rights arising
out of this Agreement,  and it shall not be necessary for any other Holder to be
joined as an additional party in any proceeding for such purpose.

            2.10 No Inconsistent Agreements.  Neither the Company nor any of its
subsidiaries has entered, as of the date hereof, nor shall the Company or any of
its  subsidiaries,  on or  after  the  date of this  Agreement,  enter  into any
agreement  with  respect  to its  securities,  that  would  have the  effect  of
impairing  the rights  granted to the  Holders in this  Agreement  or  otherwise
conflicts  with the  provisions  hereof.  Except as set forth on Schedule  2.10,
neither the Company nor any of its subsidiaries has previously  entered into any
agreement granting any registration rights with respect to any of its securities
to any Person that have not been  satisfied in full.  No Person has any right to
cause the Company to effect the  registration  under the  Securities  Act of any
securities  of the Company.  The Company  shall not file any other  registration
statements until a registration statement covering the resale of the Registrable
Securities is declared effective by the SEC.

            2.11  Remedies.  In the  event of a breach  by the  Company  or by a
Holder,  of any of their  obligations  under this Agreement,  each Holder or the
Company,  as the case may be, in  addition to being  entitled  to  exercise  all
rights granted by law and under this Agreement,  including  recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and each Holder agree that monetary  damages would not provide  adequate
compensation  for any losses  incurred by reason of a breach by it of any of the
provisions of this Agreement and hereby further agrees that, in the event of any
action for specific  performance  in respect of such breach,  it shall waive the
defense that a remedy at law would be adequate.

                              Plan of Distribution

      Each Selling Stockholder (the "Selling  Stockholders") of the common stock
("Common Stock") of [_______,  a [______  corporation (the "Company") and any of
their  pledgees,  assignees and  successors-in-interest  may, from time to time,
sell any or all of their  shares of Common  Stock on the  Trading  Market or any
other stock exchange,  market or trading facility on which the shares are traded
or in private transactions.  These sales may be at fixed or negotiated prices. A
Selling  Stockholder  may use any one or  more  of the  following  methods  when
selling shares:

      o     ordinary  brokerage  transactions  and  transactions  in  which  the
            broker-dealer solicits purchasers;

      o     block  trades in which the  broker-dealer  will  attempt to sell the
            shares as agent but may  position  and resell a portion of the block
            as principal to facilitate the transaction;

      o     purchases  by  a  broker-dealer  as  principal  and  resale  by  the
            broker-dealer for its account;

      o     an  exchange  distribution  in  accordance  with  the  rules  of the
            applicable exchange;

      o     privately negotiated transactions;

      o     settlement of short sales  entered into after the effective  date of
            the registration statement of which this prospectus is a part;

      o     broker-dealers  may agree with the  Selling  Stockholders  to sell a
            specified number of such shares at a stipulated price per share;

      o     a combination of any such methods of sale;

      o     through  the  writing or  settlement  of  options  or other  hedging
            transactions, whether through an options exchange or otherwise; or

      o     any other method permitted pursuant to applicable law.

      The Selling  Stockholders  may also sell  shares  under Rule 144 under the
Securities Act of 1933, as amended (the "Securities Act"), if available,  rather
than under this prospectus.

      Broker-dealers  engaged by the Selling  Stockholders may arrange for other
brokers-dealers to participate in sales.  Broker-dealers may receive commissions
or discounts from the Selling  Stockholders  (or, if any  broker-dealer  acts as
agent  for the  purchaser  of  shares,  from the  purchaser)  in  amounts  to be
negotiated,  but, except as set forth in a supplement to this Prospectus, in the
case of an agency transaction not in excess of a customary brokerage  commission
in compliance with NASDR Rule 2440; and in the case of a principal transaction a
markup or markdown in compliance with NASDR IM-2440.

                                      A-1
<PAGE>

      In connection with the sale of the Common Stock or interests therein,  the
Selling  Stockholders may enter into hedging transactions with broker-dealers or
other  financial  institutions,  which may in turn  engage in short sales of the
Common Stock in the course of hedging the  positions  they  assume.  The Selling
Stockholders  may also sell shares of the Common  Stock short and deliver  these
securities  to close out their  short  positions,  or loan or pledge  the Common
Stock to  broker-dealers  that in turn may sell these  securities.  The  Selling
Stockholders   may  also  enter   into   option  or  other   transactions   with
broker-dealers  or other  financial  institutions or the creation of one or more
derivative  securities which require the delivery to such broker-dealer or other
financial  institution of shares offered by this  prospectus,  which shares such
broker-dealer  or  other  financial  institution  may  resell  pursuant  to this
prospectus (as supplemented or amended to reflect such transaction).

      The  Selling  Stockholders  and any  broker~dealers  or  agents  that  are
involved  in selling  the shares may be deemed to be  "underwriters"  within the
meaning of the Securities Act in connection with such sales. In such event,  any
commissions  received  by such  broker~dealers  or agents  and any profit on the
resale  of the  shares  purchased  by  them  may be  deemed  to be  underwriting
commissions or discounts under the Securities Act. Each Selling  Stockholder has
informed  the  Company  that it does not have any written or oral  agreement  or
understanding,  directly or indirectly, with any person to distribute the Common
Stock. In no event shall any broker-dealer receive fees, commissions and markups
which, in the aggregate, would exceed eight percent (8%).

      The Company is required to pay certain fees and  expenses  incurred by the
Company  incident to the  registration of the shares.  The Company has agreed to
indemnify the Selling Stockholders against certain losses,  claims,  damages and
liabilities, including liabilities under the Securities Act.

      Because Selling Stockholders may be deemed to be "underwriters" within the
meaning of the Securities  Act, they will be subject to the prospectus  delivery
requirements of the Securities Act. In addition,  any securities covered by this
prospectus  which qualify for sale pursuant to Rule 144 under the Securities Act
may be sold under Rule 144 rather  than  under  this  prospectus.  Each  Selling
Stockholder  has advised us that they have not entered  into any written or oral
agreements, understandings or arrangements with any underwriter or broker-dealer
regarding the sale of the resale shares. There is no underwriter or coordinating
broker acting in  connection  with the proposed sale of the resale shares by the
Selling Stockholders.

      We agreed to keep this  prospectus  effective until the earlier of (i) the
date on which  the  shares  may be resold by the  Selling  Stockholders  without
registration  and  without  regard to any volume  limitations  by reason of Rule
144(e) under the  Securities Act or any other rule of similar effect or (ii) all
of the shares have been sold  pursuant to the  prospectus  or Rule 144 under the
Securities  Act or any other rule of similar  effect.  The resale shares will be
sold only through  registered or licensed  brokers or dealers if required  under
applicable  state securities  laws. In addition,  in certain states,  the resale
shares may not be sold unless they have been registered or qualified for sale in
the applicable  state or an exemption  from the  registration  or  qualification
requirement is available and is complied with.

      Under applicable rules and regulations  under the Exchange Act, any person
engaged in the distribution of the resale shares may not  simultaneously  engage
in market making  activities with respect to the Common Stock for the applicable
restricted  period, as defined in Regulation M, prior to the commencement of the
distribution.   In  addition,  the  Selling  Stockholders  will  be  subject  to
applicable  provisions  of the  Exchange  Act  and  the  rules  and  regulations
thereunder,  including Regulation M, which may limit the timing of purchases and
sales of shares of the Common  Stock by the  Selling  Stockholders  or any other
person.  We  will  make  copies  of this  prospectus  available  to the  Selling
Stockholders  and  have  informed  them of the  need to  deliver  a copy of this
prospectus to each purchaser at or prior to the time of the sale.
