number of shares  of Common  Stock  equal to no less than the sum of (A) 200% of
the  maximum  number of shares of Common  Stock  which  would be  issuable  upon

shares of Common Stock which would be issuable upon exercise of the Warrants (in
each  case,  without  regard  to any  limitations  on  conversions  or  exercise
thereof),  assuming such conversion and exercise occurred on the Initial Closing
Date or the  Filing  Date,  whichever  date  would  produce a greater  number of

allocated  among the Holders pro rata based on the total  number of  Registrable
Securities issued or issuable as of each date that a Registration  Statement, as
amended,  relating  to the  resale of the  Registrable  Securities  is  declared
effective by the Commission.  Notwithstanding  anything herein  contained to the
contrary,  if the  actual  number  of  shares  of  Common  Stock  issuable  upon

exceeds  the sum of (A) 200% of the  maximum  number of  shares of Common  Stock

         2.       Shelf Registration.

                  (a) On or prior to the Filing Date the Company  shall  prepare
and file with the  Commission  a "shelf"  Registration  Statement  covering  all
Registrable Securities for an offering to be made on a continuous basis pursuant
to Rule 415. The Registration  Statement shall be on Form SB-2 (and converted to
Form S-3 as soon as the Company  becomes  eligible  to  register  for resale the
Registrable  Securities  on Form  S-3).  The  Company  shall (i) not  permit any
securities  other  than  the  Registrable  Securities  to  be  included  in  the
Registration  Statement and (ii) use its best efforts to cause the  Registration
Statement  to be  declared  effective  under the  Securities  Act as promptly as
possible after the filing thereof,  but in any event prior to the  Effectiveness
Date, and to keep such Registration  Statement  continuously effective under the
Securities  Act  until  such  date as is the  earlier  of (x) the date  when all
Registrable  Securities covered by such Registration Statement have been sold or
(y) the  date on  which  the  Registrable  Securities  may be sold  without  any
restriction  pursuant to Rule 144(k) as determined by the counsel to the Company
pursuant to a written opinion letter,  addressed to the Company's transfer agent
to such effect (the "Effectiveness Period").

                  (b) The initial number of Registrable  Securities  included in
any  Registration  Statement  and each  increase  in the  number of  Registrable
Securities  included  therein shall be allocated  pro rata among the  Purchasers
based on the number of Registrable Securities held by each Purchaser at the time
the  Registration   Statement   covering  such  initial  number  of  Registrable
Securities or increase thereof is declared  effective by the Commission.  In the
event that a Purchaser  sells or  otherwise  transfers  any of such  Purchaser's
Registrable Securities, each transferee shall be allocated a pro rata portion of
the  then  remaining   number  of  Registrable   Securities   included  in  such
Registration Statement for such transferor.  Any shares of Common Stock included
in a  Registration  Statement  and which  remain  allocated  to any Person which
ceases to hold any Registrable Securities covered by such Registration Statement
shall be allocated to the remaining Purchasers,  pro rata based on the number of
Registrable  Securities then held by such  Purchasers  which are covered by such
Registration Statement.

                  (c) In the  event  the  number  of  shares  available  under a
Registration  Statement  filed pursuant to Section 2(a) is insufficient to cover
all of the Registrable  Securities which such Registration Statement is required
to  cover or a  Purchaser's  allocated  portion  of the  Registrable  Securities
pursuant to Section 2(b), the Company shall amend the Registration Statement, or
file a new  Registration  Statement (on the short form  available  therefor,  if
applicable),  or both,  so as to cover at least that  number of shares of Common
Stock  equal  to the sum of (x) the  product  of (i) 2 and (ii)  the  number  of
Underlying  Shares  issuable  upon  conversion  of  the  Convertible  Securities
(without  regard to any  limitations on  conversion) as of the date  immediately
preceding the date such  amendment or new  Registration  Statement is filed with
the Commission,  plus (y) the number of Warrant Shares issuable upon exercise of
the  Warrants  (without  regard to any  limitations  on exercise) as of the date
immediately  preceding the date such amendment or new Registration  Statement is
filed with the Commission,  plus (z) the number of Underlying Shares



                                      -4-


and Warrant Shares held by the Purchasers as of the date  immediately  preceding
the date on which such amendment or new Registration Statement is filed with the
Commission,  in each case,  as soon as  practicable,  but in any event not later
than fifteen (15) business days after the necessity therefor arises. The Company
shall cause such amendment and/or new Registration Statement to become effective
as soon as practicable  following the filing thereof, but in no event later than
60 days after  filing.  For purposes of the foregoing  provision,  the number of
shares available under a Registration Statement shall be deemed "insufficient to
cover all of the Registrable Securities" if the number of Registrable Securities
issued or issuable upon conversion of the Convertible Securities and exercise of
the Warrants covered by such  Registration  Statement is greater than the sum of
(a) the quotient determined by dividing (i) the number of shares of Common Stock
available for resale under the Registration  Statement to cover shares issued or
issuable upon conversion of the  Convertible  Securities by (ii) 1.5 and (b) the
number of shares of Common Stock  available  for resale  under the  Registration
Statement to cover shares issued or issuable upon exercise of the Warrants.  For
purposes  of  the  calculation  set  forth  in  the  foregoing   sentence,   any
restrictions on the convertibility of the Convertible  Securities or exercise of
the Warrants shall be  disregarded  and such  calculation  shall assume that the
Convertible  Securities  are then  convertible  into,  and the Warrants are then
exercisable for, shares of Common Stock at the then prevailing  Conversion Ratio
(as defined in the Debentures or the Amended Articles, as applicable) or Warrant
Price (as defined in the Warrants), respectively.

                  (d) The  Company  shall use its best  efforts to  qualify  for
registration  on Form S-3 or any comparable or successor  form or forms.  In the
event  that Form S-3 is not  available  for the  registration  of the  resale of
Registrable  Securities hereunder,  the Company shall (i) register the resale of
the  Registrable  Securities on another  appropriate  form and (ii) undertake to
register the resale of the  Registrable  Securities  on Form S-3 as soon as such
form is available, provided that the Company shall maintain the effectiveness of
the  Registration  Statement  then in effect  until such time as a  Registration
Statement on Form S-3  covering the  Registrable  Securities  has been  declared
effective by the Commission.

         3.       Registration Procedures.

                  In  connection  with the  Company's  registration  obligations
hereunder, the Company shall:

                  (a)Prepare  and file  with the  Commission  on or prior to the
Filing Date, a  Registration  Statement on Form SB-2  (converted  to Form S-3 as
soon as the Company  becomes  eligible to  register  for resale the  Registrable
Securities on Form S-3),  which shall be  "evergreened,"  in accordance with the
method or methods of distribution thereof as specified by the Holders (except if
otherwise  directed by the  Holders),  and cause the  Registration  Statement to
become  effective and remain effective as provided  herein;  provided,  however,
that  not  less  than  ten  (10)  Business  Days  prior  to  the  filing  of the
Registration  Statement or any related Prospectus or any amendment or supplement
thereto   (including  any  document  that  would  be  incorporated   therein  by
reference),  the  Company  shall (i)  furnish  to the  Holders  and any  Special
Counsel,  copies of all such  documents  proposed to be filed,  which  documents
(other than those  incorporated  by reference)  will be subject to the review of
such  Holders  and  such  Special



                                      -5-


Counsel,  and (ii) cause its officers  and  directors,  counsel and  independent
certified public accountants to respond to such inquiries as shall be necessary,
in the  reasonable  opinion of counsel to such Holders,  to conduct a reasonable
investigation  within the meaning of the  Securities  Act. The Company shall not
file the  Registration  Statement or any such  Prospectus  or any  amendments or
supplements  thereto  to which the  Holders  of a  majority  of the  Registrable
Securities or any Special  Counsel,  shall  reasonably  object in writing within
three (3) Business Days of their receipt thereof.

                  (b) (i) Prepare and file with the Commission such  amendments,
including  post-effective  amendments,  to the Registration  Statement as may be
necessary to keep the Registration  Statement  continuously  effective as to the

register for resale under the Securities Act all of the Registrable  Securities;
(ii) cause the related  Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule  424 (or any  similar  provisions  then in  force)  promulgated  under  the
Securities  Act; (iii) respond as promptly as possible to any comments  received
from the Commission with respect to the Registration  Statement or any amendment
thereto and as promptly as possible provide the Holders true and complete copies
of all  correspondence  from and to the Commission  relating to the Registration
Statement;  and (iv) comply in all material  respects with the provisions of the
Securities  Act and the  Exchange  Act with  respect to the  disposition  of all
Registrable   Securities  covered  by  the  Registration  Statement  during  the
applicable  period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

                  (c) Notify the Holders of  Registrable  Securities  to be sold
and any Special  Counsel as promptly  as  possible  (and,  in the case of (i)(A)
below,  not less than five (5) days prior to such  filing) and (if  requested by
any such  Person)  confirm such notice in writing no later than one (1) Business
Day following the day (i)(A) when a Prospectus or any  Prospectus  supplement or
post-effective  amendment to the Registration Statement is proposed to be filed;
(B) when the Commission notifies the Company whether there will be a "review" of
such Registration  Statement and whenever the Commission  comments in writing on
such Registration  Statement and (C) with respect to the Registration  Statement
or any post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state  governmental  authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional  information;  (iii) of the  issuance by the  Commission  of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable  Securities or the initiation of any Proceedings for that
purpose;  (iv) if at any time any of the  representations  and warranties of the
Company  contained in any  agreement  contemplated  hereby ceases to be true and
correct in all  material  respects;  (v) of the  receipt  by the  Company of any
notification  with respect to the suspension of the  qualification  or exemption
from  qualification  of  any of  the  Registrable  Securities  for  sale  in any
jurisdiction,  or the  initiation  or  threatening  of any  Proceeding  for such
purpose;  and (vi) of the  occurrence of any event that makes any statement made
in the  Registration  Statement or  Prospectus or any document  incorporated  or
deemed to be incorporated therein by reference untrue in any material respect or

                                      -6-


that requires any revisions to the Registration  Statement,  Prospectus or other
documents so that, in the case of the Registration  Statement or the Prospectus,
as the case may be, it will not contain any untrue  statement of a material fact
or omit to state any 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.

                  (d) Use its best  efforts  to avoid the  issuance  of,  or, if
issued,  obtain the withdrawal of, (i) any order suspending the effectiveness of
the  Registration  Statement or (ii) any  suspension  of the  qualification  (or
exemption from  qualification) of any of the Registrable  Securities for sale in
any jurisdiction, at the earliest practicable moment.

                  (e) If  requested  by the Holders of a majority in interest of
the Registrable Securities,  (i) promptly incorporate in a Prospectus supplement
or  post-effective  amendment to the Registration  Statement such information as
the  Company  reasonably  agrees  should be  included  therein and (ii) make all
required filings of such Prospectus supplement or such post-effective  amendment
as soon as  practicable  after the  Company  has  received  notification  of the
matters to be  incorporated  in such  Prospectus  supplement  or  post-effective
amendment.

                  (f) Furnish to each Holder and any  Special  Counsel,  without
charge,  at least one  conformed  copy of each  Registration  Statement and each
amendment thereto,  including financial statements and schedules,  all documents
incorporated  or deemed to be incorporated  therein by reference,  to the extent
requested by such Person and all exhibits to the extent requested by such Person
(including  those  previously  furnished or incorporated by reference)  promptly
after the filing of such documents with the Commission.

                  (g) Promptly  deliver to each Holder and any Special  Counsel,
without charge, as many copies of the Prospectus or Prospectuses (including each
form of prospectus) and each amendment or supplement thereto as such Persons may
reasonably  request;  and  the  Company  hereby  consents  to the  use  of  such
Prospectus  and each  amendment  or  supplement  thereto by each of the  selling
Holders in connection with the offering and sale of the  Registrable  Securities
covered by such Prospectus and any amendment or supplement thereto.

                  (h) Prior to any public  offering of  Registrable  Securities,
use its best  efforts  to  register  or qualify or  cooperate  with the  selling
Holders,  and any  Special  Counsel  in  connection  with  the  registration  or
qualification  (or exemption from such  registration or  qualification)  of such
Registrable  Securities for offer and sale under the securities or Blue Sky laws
of such  jurisdictions  within  the  United  States as any  Holder  requests  in
writing,   to  keep  each  such  registration  or  qualification  (or  exemption
therefrom) effective during the Effectiveness Period and to do any and all other
acts or  things  necessary  or  advisable  to  enable  the  disposition  in such
jurisdictions of the Registrable Securities covered by a Registration Statement;
provided,  however,  that the Company shall not be required to qualify generally
to do business in any jurisdiction  where it is not then so qualified or to take
any  action  that would  subject  it to  general  service of process in any such
jurisdiction  where it is not then so  subject  or  subject  the  Company to any
material tax in any such jurisdiction where it is not then so subject.

                                      -7-


                  (i)  Cooperate  with the  Holders  to  facilitate  the  timely
preparation and delivery of certificates  representing Registrable Securities to
be sold pursuant to a Registration  Statement,  which certificates shall be free
of all restrictive legends,  and to enable such Registrable  Securities to be in
such  denominations  and  registered in such names as any Holders may request at
least two (2) Business Days prior to any sale of Registrable Securities.

                  (j) Upon the occurrence of any event  contemplated  by Section
3(c)(vi), as promptly as possible, prepare a supplement or amendment,  including
a post-effective amendment, to the Registration Statement or a supplement to the
related  Prospectus or any document  incorporated  or deemed to be  incorporated
therein  by  reference,  and file  any  other  required  document  so  that,  as
thereafter  delivered,  neither the  Registration  Statement nor such Prospectus
will contain 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,
in the light of the circumstances under which they were made, not misleading.

                  (k) Use its best efforts to cause all  Registrable  Securities
relating to such  Registration  Statement  to be eligible  for  quotation on the
National Association of Securities Dealers,  Inc.'s OTC Bulletin Board (the "OTC
Bulletin Board") and any other securities exchange,  quotation system, market or
over-the-counter  bulletin board, if any, on which similar  securities issued by
the  Company  are then  listed as and when  required  pursuant  to the  Purchase
Agreement.

                   (l) Comply in all material respects with all applicable rules
and  regulations of the Commission and make generally  available to its security
holders  earning  statements  satisfying  the provisions of Section 11(a) of the
Securities Act and Rule 158 not later than 45 days after the end of any 12-month
period  (or 90 days  after the end of any  12-month  period if such  period is a
fiscal  year)  commencing  on the first day of the first  fiscal  quarter of the
Company after the effective date of the Registration Statement,  which statement
shall conform to the requirements of Rule 158.

                  (m) The Company may require each selling  Holder to furnish to
the  Company  information  regarding  such Holder and the  distribution  of such
Registrable Securities as is required by law to be disclosed in the Registration
Statement,  and the Company may exclude from such  registration  the Registrable
Securities of any such Holder who unreasonably fails to furnish such information
within 15 Business Days after receiving such request.

                  If the Registration  Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the  Securities  Act or any similar  federal  statute then in
force)  the  deletion  of the  reference  to such  Holder  in any  amendment  or
supplement to the  Registration  Statement  filed or prepared  subsequent to the
time that such reference ceases to be required.

                  Each Holder covenants and agrees that (i) it will not sell any
Registrable  Securities under the  Registration  Statement until it has received
copies of the  Prospectus as then


                                      -8-


amended or  supplemented  as  contemplated  in Section  3(g) and notice from the
Company  that such  Registration  Statement  and any  post-effective  amendments
thereto have become  effective as  contemplated  by Section 3(c) and (ii) it and
its officers,  directors or Affiliates,  if any, will comply with the prospectus
delivery  requirements of the Securities Act as applicable to them in connection
with sales of Registrable Securities pursuant to the Registration Statement.

                  Each  Holder  agrees by its  acquisition  of such  Registrable
Securities  that, upon receipt of a notice from the Company of the occurrence of
any  event of the kind  described  in  Section  3(c)(ii),  3(c)(iii),  3(c)(iv),
3(c)(v) or 3(c)(vi),  such Holder will forthwith discontinue disposition of such
Registrable  Securities  under the  Registration  Statement  until such Holder's
receipt of the copies of the supplemented Prospectus and/or amended Registration
Statement  contemplated  by Section 3(j), or until it is advised in writing (the
"Advice")  by the  Company  that  the use of the  applicable  Prospectus  may be
resumed,  and,  in  either  case,  has  received  copies  of any  additional  or
supplemental  filings  that are  incorporated  or deemed to be  incorporated  by
reference in such Prospectus or Registration Statement.

                  (n) If (i) there is material non-public  information regarding
the Company which the  Company's  Board of Directors  (the  "Board")  reasonably
determines  not to be in the  Company's  best interest to disclose and which the
Company is not  otherwise  required to disclose,  or (ii) there is a significant
business  opportunity  (including,  but  not  limited  to,  the  acquisition  or
disposition  of assets  (other than in the  ordinary  course of business) or any
merger,  consolidation,  tender offer or other similar transaction) available to
the Company  which the Board  reasonably  determines  not to be in the Company's
best  interest to disclose,  then the Company may postpone or suspend  filing or
effectiveness  of a  registration  statement  for a  period  not  to  exceed  15
consecutive  days,  provided  that the Company  may not  postpone or suspend its
obligation under this Section 3(n) for more than 30 days in the aggregate during
any 365-day period;  provided,  however, that no such postponement or suspension
shall be permitted for  consecutive 15 day periods,  arising out of the same set
of facts, circumstances or transactions.

                  (o) At its sole  discretion,  add the  Underlying  Shares  and
Warrant Shares to any currently filed registration  statement as an amendment to
said  registration  statement  in  order  to save  filing  and  legal  costs  in
connection with the procurement of the Registration Statement, provided that the
Company has a reasonable  belief that the registration  statement will be deemed
effective in the appropriate time period,  and further that it is not in any way
violating  any  covenants   with  other   investors  in  connection   with  such
registration statement by adding the Purchasers to said registration statement.

         4.       Registration Expenses.

                  All  fees  and  expenses  incident  to the  performance  of or
compliance  with this  Agreement  by the  Company  shall be borne by the Company
whether or not the  Registration  Statement  is filed or becomes  effective  and
whether or not any Registrable  Securities are sold pursuant to the Registration
Statement.  The fees and expenses  referred to in the foregoing  sentence  shall
include,  without  limitation,  (i) all registration and filing fees (including,
without limitation, fees and expenses (A) with respect to filings required to be
made with the National


                                      -9-


Association of Securities Dealers,  Inc. and the NASD Regulation,  Inc., and (B)
in  compliance  with  state  securities  or Blue  Sky laws  (including,  without
limitation, fees and disbursements of counsel for the Holders in connection with
Blue Sky  qualifications of the Registrable  Securities and determination of the
eligibility of the Registrable  Securities for investment under the laws of such
jurisdictions  as the  Holders  of a  majority  of  Registrable  Securities  may
designate)), (ii) printing expenses (including, without limitation,  expenses of
printing  certificates for Registrable  Securities and of printing  prospectuses
(which  may be camera  ready  copies of such  prospectuses)),  (iii)  messenger,
telephone and delivery expenses,  (iv) fees and disbursements of counsel for the
Company and Special Counsel for the Holders, in the case of the Special Counsel,
to a maximum amount of $25,000, (v) Securities Act liability  insurance,  if the
Company so  desires  such  insurance,  and (vi) fees and  expenses  of all other
Persons  retained  by the Company in  connection  with the  consummation  of the
transactions contemplated by this Agreement,  including, without limitation, the
Company's independent public accountants  (including the expenses of any comfort
letters or costs associated with the delivery by independent  public accountants
of a comfort  letter or comfort  letters).  In  addition,  the Company  shall be
responsible  for all of its internal  expenses  incurred in connection  with the
consummation  of the  transactions  contemplated  by this Agreement  (including,
without  limitation,  all salaries  and  expenses of its officers and  employees
performing  legal or accounting  duties),  the expense of any annual audit,  the
fees and expenses  incurred in  connection  with the listing of the  Registrable
Securities on any securities exchange as required hereunder.

         5.       Indemnification.

                  (a)  Indemnification  by  the  Company.   The  Company  shall,
notwithstanding  any termination of this Agreement,  indemnify and hold harmless
each Holder,  the officers,  directors,  agents,  brokers (including brokers who
offer and sell  Registrable  Securities  as principal as a result of a pledge or
any failure to perform under a margin call of Common Stock), investment advisors
and employees of each of them,  each Person who controls any such Holder (within
the meaning of Section 15 of the  Securities  Act or Section 20 of the  Exchange
Act) and the officers,  directors, agents and employees of each such controlling
Person,  to the fullest extent permitted by applicable law, from and against any
and  all  losses,  claims,  damages,  liabilities,   costs  (including,  without
limitation,   costs  of   preparation   and   attorneys'   fees)  and   expenses
(collectively,  "Losses"), as incurred, arising out of or relating to any untrue
or alleged  untrue  statement of a material fact  contained in the  Registration
Statement,  any  Prospectus  or any form of  prospectus  or in any  amendment or
supplement  thereto  or in any  preliminary  prospectus,  or  arising  out of or
relating to any omission or alleged  omission of a material  fact required to be
stated therein or necessary to make the  statements  therein (in the case of any
Prospectus  or form of prospectus  or  supplement  thereto,  in the light of the
circumstances  under which they were made) not misleading,  or arising out of or
relating to any violation by the Company or its agents of the  Securities Act or
any rule or regulation  promulgated  under the  Securities Act applicable to the
Company or its agents and relating to action or inaction required of the Company
in connection  with a registration  of Registrable  Securities  pursuant to this
Agreement,  except to the  extent,  but only to the  extent,  that  such  untrue
statements or omissions are based solely upon information  regarding such Holder
furnished  in writing to the Company by such Holder  expressly  for use therein,
which  information was reasonably relied on by the Company for use


                                      -10-


therein or to the extent  that such  information  relates to such Holder or such
Holder's  proposed  method of  distribution  of  Registrable  Securities and was
reviewed and expressly  approved in writing by such Holder  expressly for use in
the Registration Statement, such Prospectus or such form of Prospectus or in any
amendment or supplement  thereto.  The Company shall notify the Holders promptly
of the  institution,  threat or assertion of any Proceeding of which the Company
is aware in connection with the transactions contemplated by this Agreement.

                  (b) Indemnification by Holders.  Each Holder shall,  severally
and not  jointly,  indemnify  and hold  harmless  the  Company,  the  directors,
officers, agents and employees, each Person who controls the Company (within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act),
and the directors, officers, agents or employees of such controlling Persons, to
the fullest extent permitted by applicable law, from and against all Losses,  as
incurred,  arising solely out of or based solely upon any untrue  statement of a
material fact contained in the Registration  Statement,  any Prospectus,  or any
form of  prospectus,  or arising solely out of or based solely upon any omission
of a  material  fact  required  to be stated  therein or  necessary  to make the
statements  therein  (in the case of any  Prospectus  or form of  prospectus  or
supplement  thereto,  in the light of the  circumstances  under  which they were
made) not misleading,  to the extent,  but only to the extent,  that such untrue
statement or omission is contained in any information so furnished in writing by
such  Holder to the  Company  specifically  for  inclusion  in the  Registration
Statement or such  Prospectus and that such  information  was reasonably  relied
upon by the Company for use in the  Registration  Statement,  such Prospectus or
such form of prospectus or to the extent that such  information  relates to such
Holder  or  such  Holder's   proposed  method  of  distribution  of  Registrable
Securities  and was  reviewed and  expressly  approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
Prospectus.

                  (c) Conduct of Indemnification  Proceedings. If any Proceeding
shall be brought or asserted against any Person entitled to indemnity  hereunder
(an  "Indemnified  Party"),  such  Indemnified  Party  promptly shall notify the
Person from whom indemnity is sought (the "Indemnifying  Party) in writing,  and
the  Indemnifying  Party  shall  assume  the  defense  thereof,   including  the
employment of counsel  reasonably  satisfactory to the Indemnified Party and the
payment of all fees and expenses  incurred in connection  with defense  thereof;
provided,  that the failure of any  Indemnified  Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant to
this  Agreement,  except  (and  only) to the  extent  that it  shall be  finally
determined  by a court of competent  jurisdiction  (which  determination  is not
subject to appeal or further  review) that such failure  shall have  proximately
and materially adversely prejudiced the Indemnifying Party.

                  An Indemnified  Party shall have the right to employ  separate
counsel in any such  Proceeding and to participate in the defense  thereof,  but
the  fees  and  expenses  of  such  counsel  shall  be at the  expense  of  such
Indemnified  Party or Parties unless:  (1) the Indemnifying  Party has agreed in
writing to pay such fees and expenses;  or (2) the Indemnifying Party shall have
failed  promptly to assume the defense of such  Proceeding and to employ counsel
reasonably satisfactory to such Indemnified Party in any such Proceeding; or (3)
the named  parties to any such  Proceeding  (including  any  impleaded  parties)
include  both  such  Indemnified  Party  and the


                                      -11-


Indemnifying  Party,  and such  Indemnified  Party  shall  have been  advised by
counsel  that a conflict of interest is likely to exist if the same counsel were
to represent such Indemnified  Party and the Indemnifying  Party (in which case,
if such  Indemnified  Party notifies the  Indemnifying  Party in writing that it
elects to employ separate counsel at the expense of the Indemnifying  Party, the
Indemnifying  Party shall not have the right to assume the  defense  thereof and
such  counsel  shall  be  at  the  expense  of  the  Indemnifying   Party).  The
Indemnifying Party shall not be liable for any settlement of any such Proceeding
effected  without its written  consent,  which consent shall not be unreasonably
withheld.  No Indemnifying Party shall, without the prior written consent of the
Indemnified Party, effect any settlement of any pending Proceeding in respect of
which any  Indemnified  Party is a party,  unless  such  settlement  includes an
unconditional  release of such  Indemnified  Party from all  liability on claims
that are the subject matter of such Proceeding.

                  All fees and  expenses  of the  Indemnified  Party  (including
reasonable  fees  and  expenses  to  the  extent  incurred  in  connection  with
investigating   or  preparing  to  defend  such   Proceeding  in  a  manner  not
inconsistent  with this  Section)  shall be paid to the  Indemnified  Party,  as
incurred,  within  ten (10)  Business  Days of  written  notice  thereof  to the
Indemnifying  Party  (regardless of whether it is ultimately  determined that an
Indemnified Party is not entitled to indemnification  hereunder;  provided, that
the  Indemnifying  Party may require  such  Indemnified  Party to  undertake  to
reimburse  all such fees and  expenses  to the extent it is  finally  judicially
determined  that  such  Indemnified  Party is not  entitled  to  indemnification
hereunder).

                  (d) Contribution. If a claim for indemnification under Section
5(a) or 5(b) is  unavailable  to an  Indemnified  Party  because of a failure or
refusal  of  a  governmental   authority  to  enforce  such  indemnification  in
accordance  with its terms (by reason of public policy or otherwise),  then each
Indemnifying  Party,  in lieu of  indemnifying  such  Indemnified  Party,  shall
contribute to the amount paid or payable by such  Indemnified  Party as a result
of such Losses,  in such  proportion as is  appropriate  to reflect the relative
fault of the  Indemnifying  Party and  Indemnified  Party in connection with the
actions,  statements  or omissions  that  resulted in such Losses 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 any action in question,  including any untrue or alleged untrue
statement of a material fact or omission or alleged omission of a material fact,
has been  taken  or made  by,  or  relates  to  information  supplied  by,  such
Indemnifying  Party or  Indemnified  Party,  and the parties'  relative  intent,
knowledge,  access to  information  and  opportunity  to correct or prevent such
action, statement or omission. The amount paid or payable by a party as a result
of any Losses shall be deemed to include,  subject to the  limitations set forth
in Section 5(c), any reasonable  attorneys' or other reasonable fees or expenses
incurred  by such party in  connection  with any  Proceeding  to the extent such
party   would  have  been   indemnified   for  such  fees  or  expenses  if  the
indemnification  provided  for in this  Section was  available  to such party in
accordance with its terms.

                  The  parties  hereto  agree  that it  would  not be  just  and
equitable if  contribution  pursuant to this Section 5(d) were determined by pro
rata  allocation  or by any other method of  allocation  that does not take into
account the equitable  considerations  referred to in the


                                      -12-


immediately    preceding    paragraph.    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.

                  The indemnity and  contribution  agreements  contained in this
Section are in addition to any liability that the Indemnifying  Parties may have
to the Indemnified Parties.

         6.       Rule 144.

                  As long as any Holder owns Convertible Securities,  Underlying
Shares,  Warrants or Warrant  Shares,  the Company  covenants to timely file (or
obtain  extensions  in respect  thereof  and file  within the  applicable  grace
period)  all reports  required to be filed by the Company  after the date hereof
pursuant to Section  13(a) or 15(d) of the Exchange Act and to promptly  furnish
the Holders with true and complete  copies of all such  filings.  As long as any
Holder  owns  Convertible  Securities,  Underlying  Shares,  Warrants or Warrant
Shares, if the Company is not required to file reports pursuant to Section 13(a)
or 15(d) of the  Exchange  Act,  it will  prepare and furnish to the Holders and
make publicly  available in accordance  with Rule 144(c)  promulgated  under the
Securities  Act annual  and  quarterly  financial  statements,  together  with a
discussion  and  analysis of such  financial  statements  in form and  substance
substantially  similar to those that would  otherwise be required to be included
in reports  required by Section  13(a) or 15(d) of the Exchange  Act, as well as
any other  information  required  thereby,  in the time period that such filings
would have been  required to have been made under the Exchange  Act. The Company
further  covenants  that it will take such  further  action  as any  Holder  may
reasonably request,  all to the extent required from time to time to enable such
Person to sell Underlying Shares and Warrant Shares without  registration  under
the Securities Act within the limitation of the exemptions  provided by Rule 144
promulgated  under the Securities  Act,  including  providing any legal opinions
referred to in the  Purchase  Agreement.  Upon the  request of any  Holder,  the
Company  shall  deliver  to  such  Holder  a  written  certification  of a  duly
authorized officer as to whether it has complied with such requirements.

         7.       Miscellaneous.

                  (a) 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.

                  (b) No Inconsistent Agreements. Neither the Company nor any of
its subsidiaries has, as of the date hereof entered into any agreement currently
in effect,  nor shall the  Company or any of its  subsidiaries,  on or after the
date of this Agreement,  enter into any



                                      -13-


agreement with respect to its securities  that is  inconsistent  with the rights
granted  to the  Holders  in this  Agreement  or  otherwise  conflicts  with the
provisions  hereof.  Except as  disclosed  in  Schedule  2.1(s) of the  Purchase
Agreement,  neither  the  Company  nor any of its  subsidiaries  has  previously
entered into any agreement  currently in effect granting any registration rights
with  respect to any of its  securities  to any  Person.  Without  limiting  the
generality  of the  foregoing,  without the written  consent of the Holders of a
majority of the then outstanding Registrable  Securities,  the Company shall not
grant to any Person the right to request the Company to register any  securities
of the Company under the Securities Act unless the rights so granted are subject
in all respects to the prior rights in full of the Holders set forth herein, and
are not otherwise in conflict with the provisions of this Agreement.

                  (c) No Piggyback on Registrations. Neither the Company nor any
of its security holders (other than the Holders in such capacity pursuant hereto
or as  disclosed  in  Schedule  2.1(s) of the  Purchase  Agreement)  may include
securities of the Company in the Registration  Statement,  and the Company shall
not after the date hereof enter into any agreement  providing  such right to any
of its  securityholders,  unless the right so granted is subject in all respects
to the  prior  rights  in full  of the  Holders  set  forth  herein,  and is not
otherwise in conflict with the provisions of this Agreement.

                  (d) Piggy-Back Registrations. If at any time when there is not
an  effective  Registration  Statement  covering (i)  Underlying  Shares or (ii)
Warrant  Shares,  the  Company  shall  determine  to  prepare  and file with the
Commission a registration  statement relating to an offering for its own account
or the  account  of  others  under  the  Securities  Act  of  any of its  equity
securities,  other than on Form S-4 or Form S-8 (each as  promulgated  under the
Securities Act) or their then  equivalents  relating to equity  securities to be
issued solely in connection  with any  acquisition  of any entity or business or
equity  securities  issuable in connection  with stock option or other  employee
benefit plans,  the Company shall send to each Holder of Registrable  Securities
written  notice of such  determination  and,  if within  thirty  (30) days after
receipt of such  notice,  any such holder  shall so request in  writing,  (which
request shall specify the Registrable  Securities  intended to be disposed of by
the Purchasers),  the Company will cause the  registration  under the Securities
Act of all  Registrable  Securities  which the Company has been so  requested to
register by the Holder, to the extent requisite to permit the disposition of the
Registrable  Securities so to be registered,  provided that if at any time after
giving  written  notice of its intention to register any securities and prior to
the effective date of the  registration  statement filed in connection with such
registration,  the Company shall  determine for any reason not to register or to
delay  registration of such securities,  the Company may, at its election,  give
written notice of such determination to such Holder and,  thereupon,  (i) in the
case of a determination not to register,  shall be relieved of its obligation to
register any Registrable  Securities in connection with such  registration  (but
not from its  obligation to pay expenses in  accordance  with Section 4 hereof),
and (ii) in the case of a determination to delay registering, shall be permitted
to delay  registering any Registrable  Securities being  registered  pursuant to
this  Section  7(d) for the same period as the delay in  registering  such other
securities.  The Company shall include in such registration statement all or any
part of such  Registrable  Securities  such holder  requests  to be  registered;
provided,  however,  that the Company  shall not be  required  to  register  any
Registrable  Securities pursuant to this Section 7(d) that are eligible for sale
pursuant to Rule 144(k) of the


                                      -14-


Securities Act. In the case of an underwritten public offering,  if the managing
underwriter(s)  or  underwriter(s)  should reasonably object to the inclusion of
the Registrable Securities in such registration  statement,  then if the Company
after consultation with the managing  underwriter(s) should reasonably determine
that the inclusion of such Registrable  Securities,  would materially  adversely
affect the offering  contemplated in such registration  statement,  and based on
such determination  recommends inclusion in such registration statement of fewer
or none of the  Registrable  Securities  of the Holders,  then (x) the number of
Registrable  Securities of the Holders included in such  registration  statement
shall  be  reduced  pro-rata  among  such  Holders  (based  upon the  number  of
Registrable  Securities  requested to be included in the  registration),  if the
Company after consultation with the  underwriter(s)  recommends the inclusion of
fewer Registrable  Securities,  or (y) none of the Registrable Securities of the
Holders shall be included in such registration  statement,  if the Company after
consultation  with the  underwriter(s)  recommends the inclusion of none of such
Registrable Securities;  provided, however, that if Securities are being offered
for the  account  of other  persons or  entities  as well as the  Company,  such
reduction  shall not represent a greater  fraction of the number of  Registrable
Securities  intended to be offered by the Holders  than the  fraction of similar
reductions imposed on such other persons or entities (other than the Company).

                  (e)  Failure  to  File  Registration   Statement;   Rights  of
Rescission.  The Company and the  Purchasers  agree that the Holders will suffer
damages  if the  Registration  Statement  is not filed on or prior to the Filing
Date  and  not  declared  effective  by  the  Commission  on  or  prior  to  the
Effectiveness Date and maintained in the manner  contemplated  herein during the
Effectiveness Time or if certain other events occur. The Company and the Holders
further  agree that it would not be  feasible  to  ascertain  the extent of such
damages with precision.  Accordingly,  if (A) the Registration  Statement is not
filed  on or prior to the  Filing  Date,  or is not  declared  effective  by the
Commission on or prior to the Effectiveness  Date (or in the event an additional
Registration  Statement is filed  because the actual  number of shares of Common
Stock into which the Convertible Securities are convertible and the Warrants are
exercisable exceeds the number of shares of Common Stock initially registered is
not filed and declared  effective with the time periods set forth in Section 2),
or (B) the Company fails to file with the Commission a request for  acceleration
in accordance  with Rule 12dl-2  promulgated  under the Exchange Act within five
(5)  Business  Days of the date  that the  Company  is  notified  (orally  or in
writing,  whichever is earlier) by the Commission that a Registration  Statement
will  not  be  "reviewed,"  or  not  subject  to  further  review,  or  (C)  the
Registration  Statement is filed with and declared  effective by the  Commission
but thereafter  ceases to be effective as to all  Registrable  Securities at any
time  prior  to  the  expiration  of the  Effectiveness  Period,  without  being
succeeded  immediately  by a subsequent  Registration  Statement  filed with and
declared  effective by the Commission,  or (D) trading in the Common Stock shall
be suspended or if the Common Stock is delisted from the OTC Bulletin  Board for
any  reason  for more than  three  Business  Days in the  aggregate,  or (E) the
conversion rights of the Holders are suspended for any reason except as a result
of Section  4(a)(ii) of the Debentures or Section 6(a)(ii) of the Certificate of
Designation,  or (F) the Company  breaches in a material respect any covenant or
other  material  term or condition  to this  Agreement,  the Purchase  Agreement
(other than a representation  or warranty  contained  therein),  any Transaction
Document  or any other  agreement,  document,  certificate  or other  instrument
delivered in connection with the transactions  contemplated  hereby


                                      -15-


and thereby, and such breach continues for a period of thirty days after written
notice thereof to the Company,  or (G) the Company fails to convene a meeting of
shareholders  within the time period  specified  in Section 3.13 of the Purchase
Agreement or does so convene a meeting of  shareholders  within such time period
but fails to obtain Shareholder Approval at such meeting, or (H) the Company has
breached  Section  3(n) (any such  failure  or breach  being  referred  to as an
"Event,"  and for  purposes  of clauses (A) and (E) the date on which such Event
occurs,  or for purposes of clause (B) the date on which such five day period is
exceeded,  or for purposes of clause (C) after more than fifteen  Business Days,
or for  purposes of clause (D) the date on which such three  Business Day period
is  exceeded,  or for  clause  (F) the date on which  such  thirty day period is
exceeded,  being referred to as "Event Date"),  the Company shall pay in cash as
liquidated  damages to each Holder an amount equal to 2.0% per calendar month or
portion thereof of the aggregate  principal  amount of Debentures,  or aggregate
stated value of the outstanding  Preferred  Stock,  as applicable,  purchased by
such Holder,  plus the principal  amount or stated value, as applicable,  of any
Convertible  Securities  that  have  been  converted  to the  extent  any of the
Underlying  Shares  issued  upon such  conversion  have not been  sold,  and the
aggregate amount of the exercise price of the Warrants purchased by such Holder,
whether or not  exercised,  commencing on the Event Date,  until the  applicable
Event is cured.  Payments to be made  pursuant to this Section 7(e) shall be due
and payable immediately upon demand in immediately available funds.

                  (f) Amendments and Waivers.  The provisions of this Agreement,
including  the  provisions  of this  sentence,  may not be amended,  modified or
supplemented,  and waivers or consents to departures from the provisions  hereof
may not be given,  unless the same shall be in writing and signed by the Company
and each of the Holders.  Notwithstanding the foregoing,  a waiver or consent to
depart  from  the  provisions  hereof  with  respect  to a matter  that  relates
exclusively  to the rights of Holders and that does not  directly or  indirectly
affect  the  rights  of other  Holders  may be given  by  Holders  of at least a
majority of the Registrable  Securities to which such waiver or consent relates;
provided,  however,  that the  provisions  of this  sentence may not be amended,
modified,  or  supplemented  except in  accordance  with the  provisions  of the
immediately preceding sentence.

delivered by facsimile transmission, such signature shall create a valid binding
obligation  of the  party  executing  (or on  whose  behalf  such  signature  is

were the original thereof.

                  (k)  Governing  Law. This  Agreement  shall be governed by and

restriction  of  this  Agreement  is  held  to  be  invalid,  illegal,  void  or
unenforceable in any respect, 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  reasonable  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.

                  (o) Shares Held by the Company  and its  Affiliates.  Whenever
the  consent or approval of Holders of a  specified  percentage  of  Registrable
Securities is required hereunder,  Registrable Securities held by the Company or
its  Affiliates  (other than any Holder or  transferees or successors or assigns
thereof  if such  Holder is deemed  to be an  Affiliate  solely by reason of its
holdings of such  Registrable  Securities)  shall not be counted in  determining
whether  such  consent or  approval  was given by the  Holders of such  required
percentage.
