the Registrable Securities  beneficially owned by it, which notice shall specify
the intended  method or methods of disposition of such  Registrable  Securities,
the Company shall use its best efforts to effect the registration as promptly as
practicable  and  without  restriction  as  to  subsequent  trading,  under  the
Securities Act, of such  Registrable  Securities for  disposition  stated in the
request  for  registration  received  from  the  Holder : The  Company  shall be
obligated to register the Registrable Securities pursuant to this


                                      2





Section 2.1 on two (2) occasions  only with respect to notices  delivered by the

            Section 3.  Piggyback Registration.

            3.1 Notice and Registration. If the Company proposes to register any
of its  voting  securities  ("Other  Securities")  for  public  sale  under  the
Securities  Act, on a form and in a manner  which would permit  registration  of
Registrable  Securities for sale to the public under the Securities Act, it will
give prompt written notice to the Holder of its intention to do so, and upon the
written request of the Holder,  delivered to the Company within 10 business days
after the giving of any such notice (which request shall specify the Registrable
Securities  intended to be disposed of by the Holder, and the intended method of
disposition  thereof),  the  Company  will use its best  efforts to  effect,  in
connection with the registration of the Other Securities, 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  required  to permit the
disposition  (in  accordance  with the  intended  method or  methods  thereof as
aforesaid) of the Registrable Securities so to be registered, provided that:

                  (a) if, at any time after  giving such  written  notice of its
            intention  to  register  any  Other  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  the Other  Securities,  the  Company  may,  at its
            election,  give written notice of such  determination to the Holder,
            and thereupon the Company  shall be relieved of its  obligations  to
            register  such   Registrable   Securities  in  connection  with  the
            registration  of such Other  Securities (but not from its obligation
            to pay  Registration  Expenses to the extent  incurred in connection
            therewith as provided in Section 3.2), without  prejudice,  however,
            to the rights,  if any, of the Holder  immediately  to request  that
            such registration be effected as a registration under Section 2;

                  (b)  the   Company   will  not  be   required  to  effect  any
            registration of Registrable  Securities under this Section 3 if, and
            to the extent that, the underwriters  (or any managing  underwriter)
            shall  advise  the  Company  in writing  that,  in their  reasonable
            opinion,   inclusion  of  such  number  of  shares  of   Registrable
            Securities  will adversely  affect the price or  distribution of the
            securities to be offered solely for the


                                      3





            account of the Company.  Such advice shall include a statement as to
            the underwriters' (or any managing  underwriter's) opinion as to the
            number of shares which may be included without  adversely  affecting
            the price or distribution  of the securities  solely for the account
            of the Company (such total number of shares which such advice states
            may  be  so  included   being  the  "Total   Number  of   Includible
            Securities").  The Company shall promptly furnish each Holder with a
            copy of such written advice,  and in such event the number of shares
            as to which the  underwriter  believes  may be sold  shall  first be
            allocated  to the Company and the  remaining  number of shares shall
            then be allocated to the Holder.

                  (c)  The   Company   shall  not  be  required  to  effect  any
            registration  of  Registrable   Securities   under  this  Section  3
            incidental  to  the   registration  of  any  of  its  securities  in
            connection with mergers,  acquisitions,  exchange  offers,  dividend
            reinvestment plans or stock option or other employee benefit plans.

No  registration of Registrable  Securities  effected under this Section 3 shall
relieve the Company of its  obligation,  if any, to effect the  registration  of
Registrable Securities pursuant to Section 2.

            3.2 Registration  Expenses.  The Company  will pay all  Registration
Expenses  in  connection  with any  registration  pursuant  to this  Section  3;
provided that with respect to any such  registration,  the Holder shall bear any
transfer taxes applicable to its Registrable  Securities registered  thereunder,
its pro rata share of all  underwriting  fees,  commissions,  discounts or other
compensation in respect of such Registrable Securities;  and provided,  further,
that in no event shall the Holder be required to pay any  internal  costs of the
Company.

            Section 4.  Registration Procedures.

            4.1 Registration and Qualification.

            (a) If and  whenever the Company is required to use its best efforts
to effect the  registration of any Registrable  Securities  under the Securities
Act  as  provided  in  Sections  2  and  3,  the  Company  will  promptly  as is
practicable:

                  (i) prepare,  file and use its best efforts to cause to become
            effective  a  registration   statement   under  the  Securities  Act
            regarding the Registrable Securities to be offered;


                  (ii) prepare and file with the Commission  such amendments and
            supplements to such registration statement and the prospectus


                                      4





            used in  connection  therewith  as may be  necessary  to  keep  such
            registration  statement  effective and to comply with the provisions
            of  the  Securities  Act  with  respect  to the  disposition  of all
            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  Holder,  as  set  forth  in  such
            registration statement;

                  (iii)  furnish to the Holder  and to any  underwriter  of such
            Registrable  Securities  such  number  of  conformed  copies of such
            registration  statement and of each such  amendment  and  supplement
            thereto  (in the case of the  Holder  or any  managing  underwriter,
            including  all  exhibits),  such number of copies of the  prospectus
            included in such registration  statement (including each preliminary
            prospectus and any summary prospectus) or filed under the Securities
            Act, in conformity with the requirements of the Securities Act, such
            documents as may be incorporated  by reference in such  registration
            statement, or prospectus, and such other documents, as the Holder or
            such underwriter may reasonably request;

                  (iv)  use  its  best   efforts  to  register  or  qualify  all
            Registrable  Securities covered by such registration statement under
            such other securities or blue sky laws of such  jurisdictions as the
            Holder  or any  underwriter  of such  Registrable  Securities  shall
            reasonably  request,  and do any and all other acts and things which
            may  be   necessary  or  advisable  to  enable  the  Holder  or  any
            underwriter to consummate the disposition in such  jurisdictions  of
            its Registrable  Securities covered by such registration  statement,
            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 is not so qualified, or to subject itself to
            taxation in any such jurisdiction,  or to consent to general service
            of process in any such jurisdiction;

                  (v) in the case of any underwritten  offering,  furnish to the
            Holder and the  underwriters,  addressed to them,  (A) an opinion of
            counsel for the  Company,  dated the date of the  closing  under the
            underwriting  agreement  relating to any underwritten  offering,  in
            form and substance  satisfactory  to the Holder,  to the effect that
            (a) a registration statement covering the Registrable Securities has
            been filed with the Commission under the Securities Act and has been
            made  effective by order of the  Commission,  (b) such  registration
            statement  and  the  prospectus  contained  therein  comply  in  all
            material  respects with the  requirements of the Securities Act, and
            nothing has come to said counsel's attention which would cause it to
            believe that


                                      5





            either such  registration  statement or the prospectus  contains any
            untrue  statement  of a  material  fact or omits to state a material
            fact  required  to be  stated  therein  or  necessary  to  make  the
            statements  therein in light of the  circumstances  under which they
            were made not misleading,  (c) a prospectus meeting the requirements
            of the Securities  Act is available for delivery,  (d) no stop order
            has been issued by the Commission  suspending the  effectiveness  of
            such registration statement and, to the best of counsel's knowledge,
            no proceedings  for the issuance of such a stop order are threatened
            or  contemplated,  and  (e)  there  has  been  compliance  with  the
            applicable  provisions  of the  securities  or blue sky laws of each
            jurisdiction  in which the  Company  shall be  required  pursuant to
            clause (iv) of this sentence to register or qualify such Registrable
            Securities,   assuming  the  accuracy   and   completeness   of  the
            information  furnished  to such  counsel with respect to each filing
            relating  to such  laws,  and (B) a  comfort  letter  signed  by the
            independent  public  accountants  who have  certified  the Company's
            financial statements included in such registration  statement,  with
            respect  to  events   subsequent  to  the  date  of  such  financial
            statement,  as are  customarily  covered  in  accountants'  letters,
            delivered  to  underwriters  in  underwritten  public  offerings  of
            securities  and such other  matters as the  Holders  may  reasonably
            request;

                  (vi) at the  expense  of the  Holder,  give  the  Holder,  any
            underwriter(s),   and  one  counsel  or  firm  of  counsel  and  one
            accountant  or firm  of  accountants  representing  the  Holder  the
            opportunity to participate in the  preparation of such  registration
            statement,  each prospectus  included therein or filed with the SEC,
            and each amendment thereof or supplement thereto; and

                  (vii)  immediately  notify  the  Holder  at  any  time  when a
            prospectus relating to a registration  pursuant to Section 2 or 3 is
            or was required to be  delivered  under the  Securities  Act, of the
            happening of any event as a result of which the prospectus  included
            in such  registration  statement,  as then in  effect,  includes  or
            included an untrue  statement of a material fact or omits or omitted
            to  state  any  material  fact  required  to be  stated  therein  or
            necessary,  in the light of the circumstances then existing, to make
            the  statements  therein not  misleading,  and at the request of the
            Holder  prepare  and  furnish to the Holder a  reasonable  number of
            copies of a supplement of or an amendment of such  prospectus as may
            be necessary so that, as thereafter  delivered to the  purchasers of
            such  Registrable  Securities,  such prospectus shall not include an
            untrue statement of a material


                                      6





            fact or omit to state a material fact required to be stated  therein
            or necessary,  in light of the circumstances then existing,  to make
            the statements therein not misleading; and

                  (viii) use reasonable efforts to do any and all other acts the
            Holder  may  reasonably  request  and  which  are  customary  for  a
            registration of equity securities.

The Company may require the Holder to furnish such  information  regarding  such
Holder and the  distribution  of such securities as the Company may from time to
time  reasonably  request in writing  and as shall be  required by law or by the
Commission in connection with any registration.

            (b) The Holder  agrees  that,  upon  receipt of any notice  from the
Company  of the  happening  of  any  event  of the  kind  described  in  Section
4.1(a)(vi)  hereof,  the  Holder  shall  use its  best  efforts  to  discontinue
forthwith  disposition of Registrable  Securities  pursuant to the  registration
statement covering such Registrable Securities until the Holder's receipt of the
copies  of the  supplemented  or  amended  prospectus  contemplated  by  Section
4.1(a)(vi) hereof.

            4.2 Underwriting.

            (a) If requested by the managing  underwriter  for any  underwritten
offering  of  Registrable   Securities  pursuant  to  a  registration  requested
hereunder,  the  Company  will enter  into an  underwriting  agreement  with the
underwriters for such offering,  such agreement to contain such  representations
and  warranties  by the  Company  and such  other  terms and  provisions  as are
customarily  contained  in  underwriting  agreements  with  respect to secondary
distributions,  including,  without limitation,  indemnities and contribution to
the effect provided in Section 6 hereof and the provision of opinions of counsel
and  accountants'  letters to the effect provided in Section  4.1(a)(v)  hereof.
Each Holder participating in the registration, as appropriate,  shall be a party
to any such underwriting  agreement and the  representations  and warranties by,
and the other  agreements  on the part of, the Company to and for the benefit of
such underwriters, shall also be made to and for the benefit of such Holders.

            (b) In the event that any  registration  pursuant to Section 3 shall
involve, in whole or in part, an underwritten  offering, the Company may require
the Registrable  Securities  requested to be registered pursuant to Section 3 by
any Holder to be included in such  underwriting on the same terms and conditions
as shall be applicable to the Other Securities  being sold through  underwriters
under such registration. In any such case, the Holder shall be party to any such
underwriting  agreement.  Such  agreements  shall contain such  representations,
warranties and covenants by the Holder, as appropriate, and such other terms and
provisions as are customarily contained in underwriting  agreements with respect
to secondary  distributions,  including,  without  limitation,  indemnities  and
contribution to the effect provided in Section 6 hereof. The representations and
warranties in such  underwriting  agreement by, and the other  agreements on the
part of, the Company to and for the benefit of such underwriters,  shall also be
made for the benefit of the Holder.

            Section 5. Preparation: Reasonable Investigation. In connection with
the  preparation  and  filing  of  each   registration   statement   registering
Registrable  Securities  under the  Securities  Act,  the Company  will give the
Holder participating in the registration and the underwriters, if any, and their
respective  counsel  and  accountants  (collectively,  the  "Inspectors"),  such
reasonable  and  customary  access to its books and records  (collectively,  the
"Records")  and such  opportunities  to discuss the business of the Company with
its officers and the  independent  public  accountants  who have  certified  its
financial  statements  as shall be  necessary,  in the opinion of the Holder and
such  underwriters  or  their  respective   counsel,  to  conduct  a  reasonable
investigation  within  the  meaning of the  Securities  Act.  Records  which the
Company  reasonably  determines  to be  confidential  and which it notifies  the
Inspectors in writing are confidential  shall not be disclosed by the Inspectors
unless (i) the  disclosure of such Records is necessary or  appropriate to avoid
or correct a misstatement or omission in the  registration  statement,  (ii) the
portion of the Records to be disclosed  has  otherwise  become  publicly  known,
(iii) the  information  in such  Records  is to be used in  connection  with any
litigation or governmental investigation or hearing relating to any registration
statement or (iv) the release of such Records is ordered  pursuant to a subpoena
or other order.  Each Holder agrees that it will,  upon learning that disclosure
of such Records is sought in a court of competent  jurisdiction,  give notice to
the Company.

            Section 6.  Indemnification and Contribution.

                  (a)  Indemnification  By the  Company.  The Company  agrees to
indemnify and hold harmless each Person who participates as an underwriter,  the
Holder participating in a registration pursuant to this Agreement, each of their
respective officers and directors and each Person, if any, who controls any such
underwriter  or such Holder  within the meaning of Section 15 of the  Securities
Act as follows:

                  (i)  against  any and all  loss,  claim,  damage  and  expense
            whatsoever,  as  incurred,  arising  out of or caused by any  untrue
            statement or alleged  untrue  statement of a material fact contained
            in any registration statement (or any amendment thereto) pursuant to
            which  Registrable  Securities were registered  under the Securities
            Act, including all documents  incorporated therein by reference,  or
            the  omission  or alleged  omission  therefrom  of a  material  fact
            required to be stated  therein or necessary  to make the  statements
            therein not  misleading  or arising out of any untrue  statement  or
            alleged  untrue  statement  of a  material  fact  contained  in  any
            preliminary  or final  prospectus  (or any  amendment or  supplement
            thereto) or the omission or alleged omission therefrom of a material
            fact necessary in order to make the statements therein, in the light
            of the circumstances under which they were made, not misleading;

                  (ii) against any and all loss,  liability,  claim,  damage and
            expense whatsoever, as incurred, to the extent of the aggregate


                                      8





            amount paid in settlement of any  litigation,  or  investigation  or
            proceeding by any Governmental  Body commenced or threatened,  or of
            any  claim  whatsoever  based  upon any  such  untrue  statement  or
            omission, if such settlement is effected with the written consent of
            the Company; and

                  (iii)  against  any and all  expense  whatsoever,  as incurred
            (including fees and  disbursements  of counsel chosen by the Holders
            or any underwriter), reasonably incurred in investigating, preparing
            or defending against any litigation,  or investigation or proceeding
            by any  Governmental  Body,  commenced or  threatened,  or any claim
            whatsoever based upon any such untrue statement or omission,  or any
            such alleged  untrue  statement or omission,  to the extent that any
            such expense is not paid under clause (i) or (ii) above;

provided,  however,  that this  indemnity  agreement does not apply to any loss,
liability,  claim,  damage or expense to the extent  arising out of or caused by
any untrue statement or omission or alleged untrue statement or omission made in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company by the  Holder for use in a  registration  statement  (or any  amendment
thereto) or any prospectus (or any amendment or supplement thereto); and further
provided that this indemnity  agreement  does not apply to any loss,  liability,
claim,  damage or expense  arising  out of or caused by the  Holder's  continued
circulation,  subsequent  to the  Holder's  receipt of the notice  described  in
Section 4.1(a)(v)  hereof,  of a prospectus  including the untrue statement of a
material  fact or  omission  of a  material  fact as to which  such  notice  was
provided.

            (b) Indemnification by the Holder. The Holder agrees with respect to
each registration pursuant to this Agreement in which the Holder participates to
indemnify and hold harmless the Company and any  underwriter,  and each of their
respective  directors  and officers  (including  each officer of the Company who
signed the registration  statement),  and each Person,  if any, who controls the
Company or any  underwriter  within the meaning of Section 15 of the  Securities
Act and the  Holder,  against  any and all loss,  liability,  claim,  damage and
expense  described  in the  indemnity  contained  in  Section  6(a)  hereof,  as
incurred,  with respect to untrue  statements  or omissions,  or alleged  untrue
statements or omissions,  made in the  registration  statement (or any amendment
thereto) or any preliminary or final  prospectus (or any amendment or supplement
thereto) in reliance upon and in conformity with written  information  furnished
to the Company by the Holder expressly for use in the registration  statement or
such prospectus (or any amendment or supplement thereto); provided, however that
the Holder shall be liable under this  paragraph for only that amount of losses,
claims,  damages,  and liabilities as does not exceed the proceeds to the Holder
as  a  result  of  the  sale  of  Registerable   Securities   pursuant  to  such
registration.


            (c)  Promptly  after  receipt  by an  indemnified  party  under this
Section  6  of  notice  of  the  commencement  of  any  action   (including  any
governmental action), such indemnified party


                                      9





will, 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 the  indemnifying  party so desires,  jointly
with any other  indemnifying  party  similarly  noticed,  to assume the  defense
thereof with counsel mutually  satisfactory to the parties;  provided,  however,
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.  The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of
any such action,  if  prejudicial  to its ability to defend such  action,  shall
relieve such indemnifying  party of any liability to the indemnified party under
this  Section  6,  but  the  omission  so  to  deliver  written  notice  to  the
indemnifying  party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 6.

            (d) If the indemnification provided for in this Section 6 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss,  liability,  claim, damage, or expense referred to therein,
then the  indemnifying  party, in lieu of indemnifying  such  indemnified  party
hereunder,  shall  contribute to the amount paid or payable by such  indemnified
party as a result of such loss,  liability,  claim,  damage,  or expense in such
proportion as is appropriate  to reflect the relative fault of the  indemnifying
party on the one hand and of the  indemnified  party on the other in  connection
with the statements or omissions that resulted in such loss,  liability,  claim,
damage, or expense as well as any other relevant equitable  considerations.  The
relative fault of the indemnifying  party and of the indemnified  party shall be
determined by reference  to, among other  things,  whether the untrue or alleged
untrue  statement of a material  fact or the  omission to state a material  fact
relates to information  supplied by the indemnifying party or by the indemnified
party and the parties' relative intent,  knowledge,  access to information,  and
opportunity to correct or prevent such statement or omission.

            (e) Notwithstanding the foregoing, to the extent that the provisions
on  indemnification  and contribution  contained in the  underwriting  agreement
entered into in connection with the underwritten public offering are in conflict
with the foregoing  provisions,  the  provisions in the  underwriting  agreement
shall control.

            (f) The  obligations of the Company and Holders under this Section 6
shall survive the  completion of any offering of  Registrable  Securities by the
Holder and otherwise.





            Section 7.  Transferability of Shares.


                                      10





            (a)  The  shares  of any  Common  Stock  distributed  to the  Holder
pursuant to the Investment Agreement shall not be sold, assigned, transferred or
pledged except upon the conditions specified in this Section 7, which conditions
are intended to ensure  compliance  with the provisions of the  Securities  Act.
Each certificate  representing  Registrable  Securities held by the Holder shall
(unless  otherwise  permitted by the  provisions  of Section 7(b)) be stamped or
otherwise  imprinted  with a legend  in  substantially  the  following  form (in
addition to any legend required under applicable state securities laws):

            THE SHARES  REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
            UNDER THE SECURITIES ACT OF 1933 (THE "ACT).  SUCH SHARES MAY NOT BE
            SOLD OR  TRANSFERRED  EXCEPT  IN  COMPLIANCE  WITH THE  REGISTRATION
            REQUIREMENTS  OF THE ACT,  OR  PURSUANT  TO AN  EXEMPTION  FROM SUCH
            REGISTRATION REQUIREMENTS.

            (b) The Holder  understands  that, so long as the legend is required
to be  imprinted  on a  certificate  representing  Registrable  Securities,  the
Company may maintain  appropriate  "stop  transfer"  orders with respect to such
Registrable  Securities  on its books and  records and with those to whom it may
designate registrar and transfer functions.

            (c) The Holder agrees to comply in all respects with the  provisions
of this Section 7(c). Prior to any proposed sale, assignment, transfer or pledge
(a  "Transfer"),  of any  Registrable  Securities,  unless  there is in effect a
Registration  Statement  covering the proposed  Transfer,  the Holder shall give
written  notice to the Company of its  intention to effect such Transfer and the
name of the proposed transferee.  Each such notice shall describe the manner and
circumstances of the proposed Transfer in sufficient  detail,  and, if requested
by the Company, shall be accompanied,  at the Holder's expense, by either (i) an
unqualified  written  opinion of legal  counsel  who shall be,  and whose  legal
opinion  shall be,  reasonably  satisfactory  to the  Company  addressed  to the
Company, to the effect that the proposed Transfer of the Registrable  Securities
may be effected without  registration under the Securities Act; provided however
that if the proposed  Transfer  would,  in the opinion of such counsel,  require
that the Company take action and/or execute and file with the Commission  and/or
deliver  to the  Holder or any other  person  any form or  document  in order to
establish  the  entitlement  of the Holder to take  advantage  of such method of
disposition,  the Company agrees promptly to take any such action and/or execute
and file and/or deliver any such form or document,  or (ii) a "no action" letter
from the Commission to the effect that the Transfer of such  securities  without
registration  will not result in a recommendation by the staff of the Commission
that  action  be taken  with  respect  thereto,  whereupon  the  Holder  of such
Registrable  Securities  shall be  entitled  to  effectuate  a Transfer  of such
Registrable  Securities in accordance with the terms of the notice  delivered by
the Holder to the Company.  Notwithstanding the foregoing, it is agreed that the
Company  will not request an opinion of counsel  for the Holder with  respect to
Transfers  made in reliance on Rule 144 under the Act , the  existence  of which
shall be  determined  in good faith by the Board of  Directors  of the  Company;
however, the Holder shall deliver to the Company (i) copies of


                                      11





all forms  customarily  delivered or deliverable to brokers in connection with a
Transfer  of  securities,  and (ii) a  certificate  of the  Holder  desiring  to
Transfer  such  Registrable   Securities  containing  such  representations  and
warranties to the Company as are customarily given to brokers in connection with
the Transfer of securities.

            (d) Each  certificate  evidencing  the  Restricted  Securities  with
respect to which a Transfer  as provided  in this  Section 7 has been  effected,
shall bear,  except if such Transfer is made pursuant to Rule 144 under the Act,
the appropriate restrictive legend set forth above, except that such certificate
shall not bear such  restrictive  legend if in the  opinion of  counsel  for the
Holder  and the  Company  such  legend  is not  required  in order to  establish
compliance with any provision of the Act.

            (e) At any  time  when  the  Holder  desires  to make  sales  of any
Registrable  Securities in reliance on Rule 144 promulgated under the Securities
Act,  the  Company  covenants  and agrees that  either  there will be  available
adequate  current public  information with respect to the Company as required by
paragraph  (c) of said Rule 144 or the Company will use its best efforts to make
such information  available  without delay if such information is not available.
Without limiting the foregoing, the Company will timely file with the Commission
all reports  required to be filed under  Section 13 and 15(d) of the  Securities
Exchange  Act of 1934,  as  amended,  and will  promptly  furnish  to  Holder so
requesting  a written  statement  that the  Company has  complied  with all such
reporting requirements.

            (f) The Holder may assign its rights  hereunder in  connection  with
any sale, assignment, transfer or pledge of Registrable Securities provided that
such assignee shall have agreed in writing,  satisfactory  in form and substance
to the  Company and its  counsel,  to be bound  hereby.  From and after any such
assignment  pursuant to this  Section 7,  references  herein to the Holder shall
include such permitted assignee or assignees.

      8.    Rights Which May Be Granted to Subsequent Investors.

            (a) Within the limitations  prescribed by this Section 8(a), but not
otherwise,  the Company may grant to subsequent  investors in the Company rights
of piggyback  registration  (such as those  provided in Section 3 hereof).  Such
rights may only pertain to shares of Common  Stock,  including  shares of Common
Stock into  which any other  securities  may be  converted.  Such  rights may be
granted  with  respect to (i)  registrations  actually  requested  by the Holder
pursuant  to Section 2 hereof,  but only in respect of that  portion of any such
registration as remains after inclusion of all Registrable  Securities requested
by Holder and (ii) registrations  initiated by the Company,  but only in respect
of that portion of such  registration  as is available under the limitations set
forth in Section  3.1(b) hereof (which  limitations  shall apply pro rata to the
Holders and all other persons participating in the registration) and such rights
shall be limited in all cases to sharing  pro rata in the  available  portion of
the registration in question with Holder, such sharing to be based on the number
of shares of Common  Stock held by the Holder and held by such other  investors,
plus the number of shares of Common  Stock into which other  securities  held by
such other investors are convertible,


                                      12





which are entitled to registration  rights.  With respect to registrations which
are for underwritten public offerings,  "available portion" means the portion of
the underwritten  shares which is available as specified in clauses (i) and (ii)
of the  third  sentence  of this  Section  8(a).  Shares  not  included  in such
underwriting shall not be registered.

            (b) The Company may not grant to subsequent investors in the Company
rights of registration upon request (such as those provided in Section 2 hereof)
unless (i) such  rights  are  limited  to shares of Common  Stock  issued by the
Company to such  investors or to shares of Common Stock  issuable by the Company
upon the conversion of other securities issued by the Company to such investors,
(ii) such rights shall not become  effective in the period  commencing  with the
effective  date  and for  thirty  (30)  days  after  the  effective  date of the
registration  pursuant  to Section 2 hereof and (iii) such  rights  shall not be
more favorable than those granted to the Holder.

            Section 9.  Miscellaneous.

            9.1  Severability.  If any term, provision,  covenant,  restriction,
part or portion of this  Agreement is held by a court of competent  jurisdiction
to be invalid,  void or  unenforceable,  or is otherwise  legally  impossible to
perform, the remainder of the terms, provisions, covenants,  restrictions, parts
and portions of this Agreement shall remain in full force and effect.

            9.2  Specific Enforcement.  The parties hereto acknowledge and agree
that  irreparable  damage would occur in the event that any of the provisions of
this  Agreement  were not performed in accordance  with their  specific terms or
were  otherwise  breached.  It is  accordingly  agreed that the parties shall be
entitled  to  specific  performance  of any  covenant  in this  Agreement  or an
injunction or  injunctions to prevent or cure breaches of the provisions of this
Agreement,  this  being in  addition  to any other  remedy to which  they may be
entitled by law or equity.

            9.3  Entire   Agreement.   This   Agreement   contains   the  entire
understanding of the parties with respect to the matters covered hereby and this
Agreement may be amended only by an agreement in writing executed by the parties
hereto.

            9.4  Counterparts.  This Agreement may be executed in by the parties
hereto in  counterparts,  each of which shall be deemed an original,  but all of

herein  (including,  without  limitation,  any  waivers or  consents  under this
Agreement) shall be given or made by telecopy,  telegraph, cable or otherwise in
writing  (each  communication  given by any of such means to be deemed to be "in

mailed or  delivered  to the  intended  recipient  at the  address  for  notices
specified  below  or,  as to any  party,  at such  other  address  as  shall  be
designated by such party in a notice to the other.  Except as otherwise provided
in this  Agreement,  all such  communications  shall be deemed to have been duly
given  (i) when  delivered  to the  telegraph  or  cable  office  or  personally
delivered or, (ii) in the case of


                                      13





transmission by telecopy,  when telecopied (with  confirmation) and mailed (with
same day post-mark)  certified  mail,  return receipt  requested or (iii) in the
case of a mailed  notice,  upon  receipt,  in each case  given or  addressed  as
