         2.       MANDATORY REGISTRATION.

                  (i)      The   Company   shall   prepare  and  file  with  the
Securities and Exchange  Commission (the  "Commission")  not later than the 90th
day (the  "FILING  DATE")  after the  effective  date of the first  merger  (the
"MERGER")  of the Company with a company  required to file  reports  pursuant to
Section  13(a) or 15(d) of the  Securities  Exchange Act of 1934 (the  "EXCHANGE
ACT.) a Registration Statement or Registration Statements (as necessary) on Form
SB-2  covering  the resale of all of the  Registrable  Securities,  in an amount

the  "Effective  Date");  PROVIDED  THAT, if the  Registration  Statement is not
declared  effective  by the  Effective  Date then the Company  shall pay to each
Purchaser an amount equal to one percent (1%) per 30-day  period of the purchase
price paid for the Notes purchased by such Purchaser.  Thereafter,  for every 30
days that pass during which the Registration Statement has

                                       2


not  been  declared  effective,  the  Company  shall  pay to each  Purchaser  an
additional  amount equal to one percent (1%) of the purchase  price paid for the
Notes  purchased by such  Purchaser.  Each such payment shall be due within five
days of the end of each 30-day period.

                  (ii)     The Company  shall use its best  efforts to keep each
Registration  Statement  effective  pursuant to Rule 415 at all times until such
date  as is  the  earlier  of (i)  the  date  on  which  all of the  Registrable
Securities have been sold and (ii) the date on which the Registrable  Securities
(in the opinion of counsel to each Purchaser and acceptable to legal counsel for
the Company) may be  immediately  sold without  restriction  (including  without
limitation  as  to  volume   restrictions  by  each  holder   thereof)   without
registration under the Securities Act (the "REGISTRATION PERIOD").

                  (iii)    If any offering pursuant to a Registration Statement,
pursuant to Section 2 hereof,  involves an underwritten offering (which may only
be with the  consent of the  Company),  each  Purchaser  shall have the right to
select legal counsel and an investment banker or bankers and manager or managers
to administer to the offering,  which investment banker or bankers or manager or
managers shall be reasonably satisfactory to the Company.

Statements,  as may be necessary to keep the Registration effective at all times
during the Registration  Period, and, during the Registration  Period, to comply
with the provisions of the Securities Act with respect to the disposition of all
of the  Registrable  Securities  until  such  time  as all of  such  Registrable
Securities  have been  disposed of in  accordance  with the intended  methods of
disposition  by the seller or sellers  thereof as set forth in the  Registration
Statements;

                  (b)      If  the  Registrable  Securities  are  included  in a

disseminated and distributed and received by the Company,  to each Purchaser and
its  legal  counsel,  a copy of the  Registration  Statement,  each  preliminary
prospectus,  each final prospectus,  and all amendments and supplements  thereto
and such other  documents as each Purchaser may  reasonably  request in order to
facilitate the disposition of its Registrable Securities;

such other  actions as may be  necessary  to  maintain  such  registrations  and
qualifications  in effect at all times during the  Registration  Period and (iv)
take all other  actions  necessary  or  advisable  to  qualify  the  Registrable
Securities for sale in such jurisdictions, except that the Company shall not for
any such  purpose be required to qualify  generally  to do business as a foreign
corporation in any jurisdiction wherein it would not

                                       3

other securities exchanges;

for that purpose,  (iv) of the receipt by the Company of any  notification  with
respect to the suspension of the  qualification  of the  Registrable  Shares for
sale in any  jurisdiction or the initiation or threatening of any proceeding for
such  purpose,  and (v) of 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;

                  (g)      If any fact  contemplated  by clause (v) of paragraph
(f), above, shall exist, prepare a supplement or post-effective amendment to the
Registration  Statement or the related  prospectus or any document  incorporated

necessary to make the statements therein not misleading;

                  (h)      If  the  Company  has  consented  to an  underwritten

Purchasers, each of the investment advisor and sub-advisor of each Purchaser and
their officers, directors, members, partners and shareholders,  and each person,
if any, who controls any Purchasers  within the meaning of the Securities Act or
the Exchange Act (each, an "INDEMNIFIED  PERSON"),  against any losses,  claims,
damages,  liabilities  or expenses  (joint or several)  incurred  (collectively,
"CLAIMS") to which any of them may become subject under the Securities  Act, the
Exchange Act or  otherwise,  insofar as such Claims (or actions or  proceedings,
whether  commenced or threatened,  in respect thereof) arise out of or are based

subject to the  provisions  of Section  6(b) below,  reimburse  each  Purchaser,
promptly  as such  expenses  are  incurred  and are  due  and  payable,  for any
reasonable  legal and other  reasonable  costs,  expenses and  disbursements  in
giving testimony or furnishing documents in response to a subpoena or otherwise,
including without limitation, the costs, expenses and disbursements, as and when
incurred,  of  investigating,  preparing  or defending  any such  action,  suit,
proceeding or  investigation  (whether or not in connection  with  litigation in
which  such  Purchaser  is a  party),  incurred  by it in  connection  with  the
investigation  or defense of any such  Claim.  Notwithstanding  anything  to the
contrary  contained  herein,  the  indemnification  agreement  contained in this
Section  6(a)  shall not (i) apply to any Claim  arising  out of or based upon a
modification  which occurs in reliance upon and in conformity  with  information
furnished  in writing to the Company by or on behalf of any  Indemnified  Person
expressly  for  use in  connection  with  the  preparation  of the  Registration
Statement or any such amendment thereof or

                                       6


supplement  thereto;  (ii) be  available  to the extent that such Claim is based
upon a failure  of any  Purchaser  to deliver  or to cause to be  delivered  the
prospectus  made  available by the Company,  if such  prospectus was timely made
available  by the Company  pursuant to Section  3(b)  hereof;  or (iii) apply to
amounts paid in settlement of any Claim if such  settlement is effected  without
the  prior  written  consent  of  the  Company,   which  consent  shall  not  be
unreasonably  withheld.  Such  indemnity  shall  remain in full force and effect
regardless of any investigation  made by or on behalf of the Indemnified  Person
and shall  survive the transfer of the  Registrable  Securities by any Purchaser
pursuant  to  Section  9.  Notwithstanding  anything  to the  contrary  in  this
Agreement or the Purchase Agreement, the aggregate payments for indemnification,
including the reasonable fees and expenses of legal counsel, made by the Company
to each Purchaser or each of its officers, directors, and shareholders, and each
person,  if any, who controls the Purchaser within the meaning of the Securities
Act or the Exchange Act, pursuant to this Section 6 with respect to a Violation,
Claim,  or series of Violations  or Claims,  shall not exceed an amount equal to
the Purchase Price.

                  (b)      The  Purchaser  will  indemnify  the  Company and its
officers  and  directors  against  any  Claims  arising  out of or based  upon a
Violation  which  occurs in reliance  upon and in  conformity  with  information
furnished in writing to the Company, by or on behalf of the Purchaser, expressly
for  use in  connection  with  the  preparation  of the  Registration  Statement
(including any  modifications,  amendments or supplements  thereto),  subject to
such  limitations  and  conditions  as are  applicable  to  the  indemnification
provided by the Company in this Section 6; provided,  however,  that in no event
shall any indemnity by such Purchaser  under this Section 6 exceed the amount of
the net  proceeds  received by such  Purchaser in  connection  with the offering
effected through such Registration Statement.

                  (c)      Promptly after receipt by an Indemnified Person under
this  Section 6 of notice  of the  commencement  of any  action  (including  any
governmental  action),  such  Indemnified  Person  shall,  if a Claim in respect
thereof is to be made  against  any  indemnifying  party  under this  Section 6,
deliver to the indemnifying party a written notice of the commencement  thereof,
and the  indemnifying  party shall have the right to participate  in, and to the
extent  that  the  indemnifying  party  so  desires,   jointly  with  any  other
indemnifying party similarly notified,  to assume control of the defense thereof
with counsel mutually satisfactory to the indemnifying party and the Indemnified
Person,  provided,  however,  that an Indemnified Person shall have the right to
retain its own counsel with the  reasonable  fees and expenses to be paid by the
indemnifying  party,  if, in the reasonable  opinion of counsel  retained by the
indemnifying party, the representation by such counsel of the Indemnified Person
and the  indemnifying  party would be  inappropriate  due to actual or potential
differing  interests  between  such  Indemnified  Person  and  any  other  party
represented by such counsel in such proceeding. In such event, the Company shall
pay for only one  separate  legal  counsel  for the  Purchaser,  and such  legal
counsel  shall be selected  by the  Purchaser.  The  failure to deliver  written
notice to an indemnifying  party within a reasonable time after the commencement
of any such action shall not relieve such indemnifying party of any liability to
the  Indemnified  Person  under this  Section 6,  except to the extent  that the
indemnifying  party is materially  prejudiced in its ability to such action. The
indemnification required by this Section 6 shall be made by periodic payments of
the amount thereof during the course of the  investigation  or defense,  as such
expense, loss, damage or liability is incurred and is due and payable.

                  (d)      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 Person of an unconditional and irrevocable  release from all
liability in respect of such claim or litigation.

                                       7


                  (e)      Notwithstanding the foregoing, to the extent that any
provisions  relating  to  indemnification  or  contribution   contained  in  the
underwriting agreements entered into among the Company, the underwriters and the
Purchaser in connection  with the  underwritten  public offering are in conflict
with the foregoing  provisions,  the provisions in such underwriting  agreements
shall be controlling  as to the  Registrable  Securities  included in the public
offering;  PROVIDED,  HOWEVER,  that if, as a result of this Section  6(e),  the
Purchaser,  or the investment advisor or sub-investment advisor of the Purchaser
or each of its  officers,  directors,  members,  partners,  shareholders  or any
person controlling the Purchaser is or are held liable with respect to any Claim
for which they  would be  entitled  to  indemnification  hereunder  but for this
Section 6(e) in an amount which exceeds the aggregate  proceeds received by such
Purchaser  from the sale of  Registrable  Securities  included in a registration
pursuant to such underwriting  agreement (the "EXCESS  LIABILITY"),  the Company
shall reimburse the Purchaser for such Excess Liability.

         7.       CONTRIBUTION.   To  the  extent  any   indemnification  by  an
indemnifying   party  is  prohibited  or  limited  under   applicable  law,  the
indemnifying  party agrees to  contribute  to the amount paid or payable by such
indemnified party as a result of such loss, claim, damage,  liability or expense
in such  proportion  as is  appropriate  to reflect  the  relative  fault of the
indemnifying  party on the one hand and the Indemnified Person on the other hand
in connection  with the statements or omissions which resulted in such Claim, as
well as any other relevant equitable  considerations.  The relative fault of the
indemnifying  party and the Indemnified  Person shall be determined by reference
to, among other things,  whether the untrue  statement of a material fact or the
omission  to state a  material  fact on which  such  Claim is based  relates  to
information supplied by the indemnifying party or by the Indemnified Person, and
the parties' relative intent,  knowledge,  access to information and opportunity
to correct or prevent such statement or omission.  Notwithstanding the forgoing,
(a) no contribution shall be made under  circumstances where the payor would not
have been  liable for  indemnification  under the fault  standards  set forth in
Section  6,  (b) no  seller  of  Registrable  Securities  guilty  of  fraudulent
misrepresentation  (within the meaning of Section 11(f) of the  Securities  Act)
shall be entitled to contribution from any seller of Registrable  Securities who
was not guilty of such fraudulent  misrepresentation and (c) contribution by any
seller of Registrable  Securities shall be limited in amount to the net proceeds
received  by such  seller  from the  sale of such  Registrable  Securities.  The
Company  and the  Purchaser  agree  that it would not be just and  equitable  if
contribution  pursuant to this Section 7 were  determined by PRO RATA allocation
(even if any  Purchaser  and any other party were treated as one entity for such
purpose) or by any other method of allocation  that does not take account of the
equitable considerations referred to in this Section.

         8.       REPORTS UNDER EXCHANGE ACT. With a view to making available to
the Purchasers the benefits of Rule 144 promulgated  under the Securities Act or
any other  similar rule or  regulation  of the  Commission  that may at any time
permit the  Purchasers to sell  securities of the Company to the public  without
registration  ("RULE 144"),  after the Merger,  the Company  agrees to cause its
successor in interest by merger to:

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

                           (ii)     file with the  Commission in a timely manner
all reports and other documents required of the Company under the Securities Act
and the Exchange Act; and

                           (iii)    furnish  to any  Purchaser  so  long as such
Purchaser owns Shares or Notes promptly upon request, (i) a written statement by
the  Company  that  it has  complied  with  the  reporting  requirements  of the
Securities  Act and the Exchange  Act,  (ii) a copy of the most recent annual or
periodic  report of the Company and such other reports and documents so filed by
the Company and (iii) such other  information as may be reasonably  requested to
permit  the  Purchaser  to sell such  securities  pursuant  to Rule 144  without
registration.

                                       8


         9.       ASSIGNMENT OF THE REGISTRATION  RIGHTS. The rights to have the
Company  register  Registrable  Securities  pursuant to this Agreement  shall be
automatically assigned by any Purchaser to any transferee of the Shares or Notes
held by such  Purchaser  if:  (a) such  Purchaser  agrees  in  writing  with the
transferee  or assignee to assign such rights,  and a copy of such  agreement is
furnished to the Company within a reasonable time after such assignment; (b) the
Company is, at the time of such  transfer  within five  business days after such
transfer or assignment, furnished with written notice of the name and address of
such transferee or assignee;  (c) at or before the time the Company receives the
written notice  contemplated  by clause (b) of this sentence,  the transferee or
assignee agrees in writing with the Company to be bound by all of the provisions
contained herein;  and (d) the transfer of the relevant Shares complies with the
restrictions set forth in Section 4 of the Purchase Agreement.

         10.      AMENDMENT  OF  REGISTRATION  RIGHTS.  Any  provision  of  this
Agreement  may be  amended  and the  observance  thereof  may be waived  (either
generally   or  in  a   particular   instance   and  either   retroactively   or
prospectively),  only with the  written  consent  of the  Company  and each such
Purchaser.  Any amendment or waiver  effected in accordance with this Section 10
shall be binding upon such Purchaser and the Company.

         11.      MISCELLANEOUS.

                  (a)      A person  or  entity  is  deemed  to be a  holder  of
Registrable  Securities  whenever  such  person  or entity  owns of record  such
Registrable Securities or Notes convertible into such Registrable Securities. If
the Company receives conflicting instructions,  notices or elections from two or
more persons or entities with respect to the same  Registrable  Securities,  the
Company  shall  act  upon the  basis of the  instructions,  notice  or  election
received from the registered owner of such Registrable Securities or Notes.

                  (b)      Any notice  required or permitted  hereunder shall be
given in writing (unless otherwise specified herein) and shall be effective upon
personal  delivery,  via facsimile  (upon receipt of  confirmation of error-free
transmission)  or two  business  days  following  deposit of such notice with an
internationally  recognized courier service,  with postage prepaid and addressed
to each of the other parties thereunto entitled at (i) if to the Company, to the
address set forth below in this Section 11(b), or (ii) if to a Purchaser, to the
address set forth below such  Purchaser's  name on the signature page below,  or
(iii) at such other  addresses as a party may designate by ten (10) days advance
written notice to each of the other parties hereto.

                  (c)      Failure of any party to exercise  any right or remedy
under this Agreement or otherwise,  or delay by a party in exercising such right
or remedy, shall not operate as a waiver thereof.

                  (d)      This Agreement  shall be governed by and  interpreted
in accordance  with the laws of the State of New York,  without giving effect to
conflicts of laws issues.  Each of the parties agrees to the jurisdiction of the
federal courts whose districts encompass any part of the City of New York or the
state  courts  of the  State  of New  York  sitting  in the  City of New York in
connection with any dispute  arising under this Agreement and hereby waives,  to
the maximum  extent  permitted by law, any  objection,  including  any objection
based on FORUM NON  CONVENIENS,  to the bringing of any such  proceeding in such
jurisdictions. This Agreement may be signed in two or more counterparts, each of
which  shall be deemed an  original.  The  headings  of this  Agreement  are for
convenience   of   reference   and  shall  not  form  part  of,  or  affect  the
interpretation  of, this Agreement.  If any provision of this Agreement shall be
invalid or unenforceable in any jurisdiction,  such validity or unenforceability
shall not  affect  the  validity  or  enforceability  of the  remainder  of this
Agreement  or the  validity or  enforceability  of this  Agreement  in any other
jurisdiction. Subject to the provisions of Section 10 hereof, this Agreement may
be amended only by an  instrument  in writing  signed by the party to be charged
with enforcement.

                  (e)      This Agreement,  together with the other  Transaction
Documents,  constitutes  the entire  agreement  among the  parties  hereto  with
respect to the  subject  matter  hereof.  This  Agreement  supersedes  all prior
agreements  and  understandings  among the parties  hereto  with  respect to the
subject matter hereof.

                  (f)      Subject to the requirements of Section 9 hereof, this
Agreement  shall inure for the benefit of and be binding upon the successors and
assigns of each of the parties hereto.

                  (g)      All pronouns and any variations  thereof refer to the
masculine, feminine or neuter, singular or plural, as the context may require.

                  (h)      The  Company  acknowledges  that any  failure  by the
Company  to  perform  its  obligations  under  Section  2, or any  delay in such
performance  could result in direct and indirect damages to the Purchasers,  and
the Company agrees that,  after notice and time to cure in addition to any other
liability  the  Company  may have by reason of any such  failure  or delay,  the
Company shall be liable for all direct and  consequential  damages caused by any
such  failure or delay.  Nothing  herein shall limit each  Purchaser's  right to
pursue any claim seeking such direct or consequential damages.

                                       11


         IN WITNESS WHEREOF,  the parties have caused this  Registration  Rights
Agreement to be executed as of the date first written above.
