     A. The Company and  Purchasers  have entered  into the Purchase  Agreement,
pursuant to which the  Purchasers  are  purchasing  that number of shares of the
Series A Preferred  Stock of the Company  ("Series A  Preferred")  specified  in
Section 1.1 of the Purchase  Agreement,  subject to the terms  provided  therein
(the "Investment Securities").

     B. As a  condition  to the  consummation  of the  Purchase  Agreement,  the
Purchase  Agreement  provides  that the  Purchasers  of Series A  Preferred  may
convert such Series A Preferred into Common Stock,  and shall be granted certain

     NOW,  THEREFORE,  in  consideration  of the  agreements  set  forth  in the
Purchase  Agreement and of the mutual  agreements and covenants  hereinafter and
therein contained, the parties hereto agree as follows:

                                    AGREEMENT

     1. REGISTRATION RIGHTS.

          1.1 Definitions. For purposes of this Section 1:

               (a)  Registration.   The  terms  "register,"   "registered,"  and
"registration"  refer to a  registration  effected  by  preparing  and  filing a
registration statement in compliance with the Securities Act of 1933, as amended
(the "Securities Act"), and the declaration or ordering of effectiveness of such
registration statement.

               (b) Registrable  Securities.  The term  "Registrable  Securities"
means: any shares of Common Stock of the Company issued as (or issuable upon the
conversion or exercise of any warrant,  right or other  security which is issued
as) a dividend  or other  distribution  with  respect  to, or in  conversion  or
exchange for, or in replacement  of Series A Preferred;  excluding in all cases,
however,  any Registrable  Securities sold by a person in a transaction in


                                                                          Page 1


which  rights  under this  Section 1 are not  assigned in  accordance  with this
Agreement or any Registrable  Securities sold or eligible for sale to the public
or sold,  or  eligible  for sale,  pursuant  to Rule 144  promulgated  under the
Securities Act.

               (c) SEC. The term "SEC or "Commission" means the U.S.  Securities
and Exchange Commission.

               (d) Closing  Date.  The term  "Closing  Date" shall have the same
meaning that is given to such term in the Purchase Agreement.

          1.2 Demand Registration.

               (a) Request by the Purchasers.  At any time after sixty (60) days
after  the  Closing  Date if the  Company  shall  receive  at any time a written
request  ("Request")  from  New  Century  requesting  that  the  Company  file a
registration  statement  under the Securities Act covering the  registration  of
Registrable  Securities  pursuant to this  Section 1.2,  then the Company  shall
effect the registration  under the Securities Act of all Registrable  Securities
within ninety (90) days of such request.

               (b)  Underwriting.  The  Registrable  Securities  covered  by the
Request may be offered by means of an  underwriting if a majority of the holders
of the Series A Preferred so request and the Company so consents,  which consent
will not be unreasonably withheld, and a majority of the holders of the Series A
Preferred  shall  so  advise  the  Company  as a  part  of  its  Request.  If an
underwriting is requested by a majority of the holders of the Series A Preferred
in their  Request,  then  such  holders  and the  Company  shall  enter  into an
underwriting  agreement  in  customary  form with the  managing  underwriter  or
underwriters  selected  for such  underwriting  by the mutual  agreement  of the
Company and such  holders;  provided,  that neither the Company nor such holders
shall  unreasonably  refuse to agree to a managing  underwriter  selected by the
other,  but shall in good faith attempt to select  mutually  agreeable  managing
underwriters.  Notwithstanding  any other  provision of this Section 1.2, if the
underwriters  advise the Company in writing  that  marketing  factors  require a
limitation  of the number of  securities  to be  underwritten,  then the Company
shall so advise such holders, and the number of Registrable  Securities that may
be  included  in  the   underwriting   shall  be  reduced  as  required  by  the
underwriters;  provided,  that the number of shares of Registrable Securities to
be included in such underwriting and registration shall be reduced on a pro rata
basis with all other  securities of the Company and any other  selling  security
holder. Any Registrable Securities excluded and withdrawn from such underwriting
shall be withdrawn from the registration.

               (c)  Maximum  Number  of Demand  Registrations.  The  Company  is
obligated to effect only two (2) such registration pursuant to this Section 1.2.

               (d) Expenses.  The Company shall bear all direct costs related to
the  registration,  including,  without  limitation,  all federal and "blue sky"
registration  and  qualification  fees,  printers' and accounting fees, fees and
disbursements of counsel for the Company.  The selling  stockholders  shall bear
all underwriting  discounts and commission


                                                                          Page 2


payable in connection with their sale of shares hereunder.

               (e)  Rights  of  the  Company.  Notwithstanding  anything  to the
contrary in this Section 1.2 or otherwise in this  Agreement,  the Company shall
not be obligated to take any action to effect any such registration  pursuant to
this Section 1.2 as follows:

                    (i) In any  particular  jurisdiction  in which  the  Company
would be  required  to  execute a general  consent  to  service  of  process  in
effecting such registration  unless the Company is already subject to service in
such jurisdiction and except as may be required by the Securities Act;

                    (ii) If the Company,  within ten (10) days of the receipt of
a registration Request under Section 1.2, gives written notice to the holders of
all  Series A  Preferred  of the  Company's  bona fide  intention  to effect the
filing,   within  forty-five  (45)  days  of  receipt  of  such  Request,  of  a
registration  statement  with the  Commission  for the sale of securities by the
Company (other than with respect to a registration  statement relating to a Rule
145 transaction, an offering solely to employees or any other registration which
is not appropriate for the  registration  of Registrable  Securities),  in which
event,  (x) the holders of all Series A Preferred  shall be entitled to exercise
their  piggyback  registration  rights under  Section 1.3 hereof with respect to
such registration, (y) the Company shall be required in good faith to employ all
reasonable  efforts to cause its registration  statement to become effective and
to give prompt  written  notice to the holders of all Series A Preferred  if the
Company  abandons  its effort to file or causes its  registration  statement  to
become  effective,  and (z) in the event the  Company  gives  notice that it has
abandoned its registration  statement efforts,  the Company shall promptly renew
its best efforts to register the Registrable Securities that were the subject of
the Series A Preferred demand registration Request if so requested in writing by
the holders of all Series A within ten (10) days after the holders of all Series
A Preferred's  receipt of notice that the Company has abandoned its registration
efforts;

                    (iii)  During  the  period  starting  with the filing of and
ending on the date ninety (90) days immediately  following the effective date of
any registration statement pertaining to securities of the Company (other than a
registration  of  securities  in a Rule 145  transaction  or with  respect to an
employee benefit plan),  provided that the Company is actively employing in good
faith all  reasonable  efforts to cause such  registration  statement  to become
effective;

                    (iv) If the Company shall furnish to the holders of Series A
Preferred a certificate  signed by the President of the Company  stating that in
the good faith  judgment  of the Board of  Directors  of the Company it would be
seriously detrimental,  for the specific reasons stated in such certificate,  to
the Company or its shareholders for a registration


                                                                          Page 3


statement to be filed in the near future,  then the Company's  obligation to use
its best  efforts to register  under this  Section  1.2 shall be deferred  for a
period not to exceed one hundred and twenty  (120) days from the date of receipt
of the written Request from the holders of Series A Preferred; or

                    (v) Unless at least one hundred and eighty  (180) days shall
have expired from the  effectiveness  of a previous  registration of Registrable
Securities pursuant to this Section 1.2, or pursuant to a previous  registration
under  Section  1.3 below in which the  holders of shares of Series A  Preferred
were given the  opportunity to include in such  registration at least the lesser
of (i)  twenty-five  percent  (25%) of the  Registrable  Securities  held by the
holders of Series A Preferred,  or (ii) all Registrable Securities then owned by
the holders of Preferred shares.

Subject to the foregoing clauses (i) through (v), the Company shall file a
registration statement covering the Registrable Securities so requested to be
registered as soon as practicable after receipt of the request or requests of
the holders of Series A Preferred.

          1.3 Piggyback  Registrations.  The Company shall notify the holders of
Series A  Preferred  in  writing at least  twenty  (20) days prior to filing any
registration  statement  under the  Securities  Act for  purposes of effecting a
public  offering of  securities of the Company  (including,  but not limited to,
registration  statements  relating to secondary  offerings of  securities of the
Company,   but  excluding   registration   statements  relating  solely  to  any
registration under Section 1.2 of this Agreement or any employee benefit plan or
a Rule 145  transaction)  and will  afford the  holders  of Series A  Preferred,
subject to the terms and conditions set forth herein,  an opportunity to include
in such  registration  statement all or any part of the  Registrable  Securities
then  held by the  holders  of  shares  of  Series  A. The  holders  of Series A
Preferred   shall,   within  five  (5)  business   days  after  receipt  of  the
above-described  notice from the Company, so notify the Company in writing,  and
in such notice shall inform the Company of the number of Registrable  Securities
the  holders  of Series A  Preferred  wishes  to  include  in such  registration
statement.  If the  holders of Series A  Preferred  decide not to include all of
their Registrable  Securities in any registration  statement thereafter filed by
the Company,  the holders of Series A Preferred shall  nevertheless  continue to
have the right to  include  any  Registrable  Securities  not  included  in such
registration statement in any subsequent  registration statement or registration
statements  as may be filed by the  Company  with  respect to  offerings  of its
securities,  all upon the terms and conditions set forth herein.  If the holders
of Series A Preferred are given the  opportunity to include in any  registration
statement  filed under this  Section 1.3 at least the lesser of (i)  twenty-five
percent (25%) of the  Registrable  Securities  issued to the holders of Series A
Preferred  pursuant to the Agreement,  or (ii) all  Registrable  Securities then
owned by the  holders  of  Series A  Preferred,  then the  holders  of  Series A
Preferred shall not make a request for registration under Section 1.2 hereof for
at least one hundred and eighty (180) days after the earlier of the  termination
of such offering or the effectiveness of such registration statement.

               (a)  Underwriting.  If a registration  statement  under which the
Company  gives notice under this  Section 1.3 is for an  underwritten  offering,
then the  Company  shall so


                                                                          Page 4


advise the holders of Series A Preferred. In such event, the holders of Series A
Preferred's right to include Registrable  Securities in a registration  pursuant
to this  Section  1.3 shall be  conditioned  upon the  holders  of the  Series A
Preferred s  participation  in the extent  provided  herein.  The holders of the
Series A Preferred shall enter into an underwriting  agreement in customary form
with the managing  underwriter or underwriters  selected by the Company for such
underwriting. Notwithstanding any other provision of this Purchase Agreement, if
the managing underwriter determines in good faith that marketing factors require
a  limitation  of the  number of shares to be  underwritten,  then the  managing
underwriters  may exclude shares  (including  Registrable  Securities)  from the
registration and the underwriting, and the number of shares that may be included
in the  registration  and the  underwriting  shall be allocated,  first,  to the
Company, and second to the holders of the Series A Preferred;  provided however,
that the right of the  underwriters  to exclude  shares  (including  Registrable
Securities)  from the  registration and underwriting as described above shall be
restricted so that: (i) all shares that are not  Registrable  Securities and are
held by other  shareholders  of the Company,  (except  those  shareholders  with
registration  rights that, as of the Effective  Date of the Purchase  Agreement,
are senior to or on a pari passu basis with those of the holders of the Series A
Preferred  and are  disclosed  to the holders of the Series A  Preferred  in the
Purchase  Agreement  or any  disclosure  letter  delivered to the holders of the
Series A Preferred  pursuant to the Purchase  Agreement),  shall be reduced on a
pro rata basis with all other  securities  of the Company and any other  selling
security holder; and (ii) the number of Registrable  Securities  included in any
such  registration  is not  reduced  below  twenty  percent  (20%) of the shares
included in the  registration,  except if such lesser number of shares is caused
because of the pro rata reduction of (i) above.  If a majority of the holders of
the Series A Preferred  disapprove  of the terms of any such  underwriting,  the
Series A Preferred  may elect to  withdraw  therefrom  by written  notice to the
Company and the managing underwriter,  delivered at least ten (10) business days
prior to the  effective  date of the  registration  statement.  Any  Registrable
Securities  excluded or withdrawn from such  underwriting  shall be excluded and
withdrawn from the registration.

               (b)  Expenses.  The holders of Series A Preferred  shall bear all
discounts,  commissions or other amounts payable to underwriters or brokers with
respect to the sale of  Registrable  Securities  by the  holders of the Series A
Preferred  in any  offering  registered  under  this  Section  1.3 and  fees and
disbursements of counsel for the holders of the Series A Preferred in connection
with such offering.  Other expenses  incurred in connection  with a registration
pursuant to this  Section 1.3,  including,  without  limitation  all federal and
"blue sky"  registration and qualification  fees,  printers and accounting fees,
and fees and  disbursements  of counsel  for the  Company  shall be borne by the
Company.


                                                                          Page 5


          1.4.  Obligations  of the  Company.  Whenever  required  to effect the
registration of any Registrable  Securities under this Agreement,  and except as
otherwise  provided in this Section or otherwise in this Agreement,  the Company
shall, as expeditiously as reasonably possible:

               (a)  Prepare  promptly  and  file  with  the  SEC a  registration
statement with respect to such  Registrable  Securities and use its best efforts
to cause  such  registration  statement  to  become  effective,  and,  keep such
registration statement effective for ninety (90) days (or until the earlier sale
of the Registrable  Securities covered thereby),  which  registration  statement
(including  any  amendments or supplements  thereto and  prospectuses  contained
therein)  shall not contain any 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 light of the circumstances in which they were made, not
misleading.

               (b) Prepare  promptly and file with the SEC such  amendments  and
supplements to such registration statement and the prospectus used in connection
with  such  registration  statement  as may be  necessary  to  comply  with  the
provisions  of  the  Securities  Act  with  respect  to the  disposition  of all
securities covered by such registration statement.

               (c) Furnish to the Series A Preferred shareholders such number of
copies of a prospectus,  including a preliminary prospectus,  in conformity with
the  requirements  of the  Securities  Act,  and such other  documents as it may
reasonably  request in order to facilitate the  disposition  of the  Registrable
Securities owned by it that are included in such registration.

               (d) Use its best efforts to register  and qualify the  securities
covered by such  registration  statement under such other securities or Blue Sky
laws of such  jurisdictions  as shall be reasonably  requested by the holders of
Series A  Preferred,  provided,  that  the  Company  shall  not be  required  in
connection  therewith or as a condition  thereto to qualify to do business or to
file  a  general   consent  to  service  of  process  in  any  such   states  or
jurisdictions.

               (e) In the event of any underwritten public offering,  enter into
and  perform  its  obligations  under an  underwriting  agreement,  in usual and
customary form, with the managing underwriters of such offering.

               (f) Notify the Series A Preferred shareholders at any time when a
prospectus  relating to the  Registrable  Securities is 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
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)   Furnish,   at  the   request  of  the  Series  A  Preferred
shareholders,  on the date that such Registrable Securities are delivered to the
underwriters  for sale, if such securities are being sold through  underwriters,
or, if such securities are not being sold through underwriters, on the date that
the registration  statement with respect to such securities  becomes


                                                                          Page 6


effective,  (i) an opinion,  dated as of such date, of the counsel  representing
the Company for the purposes of such  registration,  in form and substance as is
customarily  given  to  underwriters  in an  underwritten  public  offering  and
reasonably satisfactory to the Series A Preferred shareholders, addressed to the
underwriters,  if any,  and to the Series A Preferred  shareholders,  and (ii) a
"comfort"  letter dated as of such date, from the independent  certified  public
accountants  of the Company,  in form and substance as is  customarily  given by
independent  certified  public  accountants to  underwriters  in an underwritten
public  offering  and  reasonably  satisfactory  to a  the  Series  A  Preferred

Preferred shareholders.

               (h) Make generally  available to its security  holders as soon as
practical,  but not later  than  ninety  (90) days after the close of the period

beginning  not later than the first day of the  Company's  fiscal  quarter  next
following   the   effective   date  of  any   registration   statement  and  any
post-effective amendment thereto.

               (i)  Cooperate  with the  Series A  Preferred  shareholders,  any
underwriter   participating   in  any   underwritten   offering  of  Registrable
Securities, and any attorney, accountant or other agent retained by the Series A
Preferred  shareholders  or any such  underwriter  by providing any  information
reasonably  requested by any such persons in connection with their due diligence
investigation  relating to the filing of the registration  statement relating to
the Registrable Securities.

               (j) Use its best efforts to cause all the Registrable  Securities
covered by any  registration  statement  to be listed on a  national  securities
exchange,  if the Common Stock is then listed on a national  securities exchange
and the listing of such Registrable Securities is then permitted under the rules
of such exchange.

               (k) Provide a transfer agent and registrar, which may be a single
entity, for the Registrable  Securities not later than the effective date of any
registration statement.

               (l) Cooperate  with the Series A Preferred  shareholders  and the
managing  underwriter  or  underwriters  of any offering  involving  Registrable
Securities,  if any,  to  facilitate  the timely  preparation  and  delivery  of

Securities to be sold pursuant to a  registration  effected  hereto,  and enable
such certificates to be in such denominations or amounts as the case may be, and

facilitate  the  disposition  of  the  Registrable  Securities  pursuant  to the
registration statement.

          1.5  Furnish  Information.  It shall be a condition  precedent  to the
obligations  of


                                                                          Page 7


the Company to take any action pursuant to Sections 1.2, or1.3 that the Series A
Preferred  shareholders shall furnish to the Company such information  regarding
it,  the  Registrable  Securities  held  by  it,  and  the  intended  method  of
disposition  of such  securities  as shall be  required  to  timely  effect  the
registration of its Registrable Securities.

          1.6  Indemnification.  In the event  any  Registrable  Securities  are
included in a registration statement under 1.2 or 1.3:

               (a) By the Company.  To the extent  permitted by law, the Company
will indemnify and hold harmless the Series A Preferred  shareholders,  officers
and  directors  of the Series A  Preferred  shareholders,  any  underwriter  (as
defined in the Securities Act) for the Series A Preferred  shareholders and each
person,  if any,  who  controls  the  Series A  Preferred  shareholders  or such
underwriter within the meaning of the Securities Act or the Securities  Exchange
Act of 1934, as amended (the "1934 Act"), against any losses,  claims,  damages,
or  liabilities  (joint or several) to which they may become  subject  under the
Securities  Act,  the 1934 Act or other  federal or state  law,  insofar as such
losses,  claims,  damages,  or liabilities (or actions in respect thereof) arise
out  of or  are  based  upon  any  of the  following  statements,  omissions  or
violations (collectively a "Violation"):

          (i) any untrue  statement  or alleged  untrue  statement of a material
fact  contained in a  registration  statement  filed pursuant to this Section 1,
including any preliminary prospectus or final prospectus contained therein or in
any amendments or supplements thereto;

          (ii) the  omission  or  alleged  omission  to state in a  registration
statement filed pursuant to this Section 1 (including any preliminary prospectus
or final  prospectus  contained  therein  or in any  amendments  or  supplements
thereto),  a material fact required to be stated  therein,  or necessary to make
the statements therein not misleading; or

          (iii)  any  violation  or  alleged  violation  by the  Company  of the
Securities Act, the 1934 Act, any federal or state securities law or any rule or
regulation  promulgated under the Securities Act, the 1934 Act or any federal or
state   securities  law  in  connection  with  the  offering   covered  by  such
registration statement;

and the Company will reimburse each of the Series A Preferred shareholders, such
officer or director,  underwriter or  controlling  person for any legal or other
expenses  reasonably   incurred  by  them,  as  incurred,   in  connection  with
investigating or defending any such loss,  claim,  damage,  liability or action,
provided  however,  that the indemnity  agreement  contained in this  subsection
1.6(a) shall not apply to amounts paid in  settlement  of any such loss,  claim,
damage,  liability or action if such settlement is effected  without the consent
of the Company (which consent shall not be unreasonably withheld), nor shall the
Company be liable in any such case for any such loss, claim,  damage,  liability
or action to the extent that it arises out of or is based upon a Violation which
occurs in reliance upon and in conformity with information  furnished  expressly
for  use in  connection  with  such  registration  by  the  Series  A  Preferred
shareholders, or by such, officer, director,  underwriter or controlling person,
or other authorized agents, of the Series A Preferred shareholders.


                                                                          Page 8


               (b)  By the  Series  A  Preferred  Shareholders.  To  the  extent
permitted by law, the Series A Preferred  shareholders  will  indemnify and hold
harmless the Company, each of its directors,  each of its officers, each person,

several) to which the Company or any such director, officer,  controlling person
or  underwriter  may become  subject under the  Securities  Act, the 1934 Act or
other  federal  or  state  law,  insofar  as such  losses,  claims,  damages  or
liabilities (or actions in respect thereto) (1) arise out of or are based upon a
Violation,  in each  case to the  extent  (and  only to the  extent)  that  such
Violation occurs in reliance upon and in conformity with  information  furnished
by the Series A Preferred shareholders expressly for use in connection with such
registration,  or (ii)  any  violation  or  alleged  violation  by the  Series A
Preferred shareholders of the Securities Act, the 1934 Act, any federal or state
securities law or any rule or regulation  promulgated  under the Securities Act,
the 1934 Act or any  federal  or state  securities  law in  connection  with the
offering  covered by such  registration  statement;  and the Series A  Preferred
shareholders will reimburse any legal or other expenses  reasonably  incurred by
the Company or any such director,  officer,  controlling person,  underwriter in
connection  with  investigating  or  defending  any such  loss,  claim,  damage,
liability or action; provided however, that the indemnity agreement contained in
this subsection 1.6(b) shall not apply to amounts paid in settlement of any such
loss, claim, damage,  liability or action if such settlement is effected without
the consent of the Series A Preferred  shareholders,  which consent shall not be
unreasonably  withheld;  and provided further, that the total amounts payable in
indemnity by the Series A Preferred  shareholders  under this Section  1.6(b) in
respect  of any  Violation  shall not exceed the net  proceeds  received  by the
Series A Preferred  shareholders  in the  registered  offering out of which such
Violation arises.

               (c) Notice.  Promptly after receipt by an indemnified party under
this  Section 1.6 of notice of the  commencement  of any action  (including  any
governmental   action),   such   indemnified   party   will,   if  a  claim  for
indemnification  in respect thereof is to be made against any indemnifying party
under this Section 1.6,  deliver to the  indemnifying  party a written notice of
the  commencement  of such an action 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  shall  have the right to  retain  its own
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 conflict of
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
1.6, 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 1.6.

               (d)  Defect  Eliminated  in  Final   Prospectus.   The  foregoing
indemnity  agreements  of the Company and Series A  Preferred  shareholders  are
subject to the condition that,


                                                                          Page 9


insofar as they relate to any  Violation  made in a preliminary  prospectus  but
eliminated  or remedied in the  amended  prospectus  on file with the SEC at the
time the registration  statement in question becomes effective or in the amended
prospectus  filed  with  the  SEC  pursuant  to  SEC  Rule  424(b)  (the  "Final
Prospectus"),  such indemnity  agreements  shall not inure to the benefit of any
person if a copy of the Final Prospectus was furnished to the indemnified  party
and was not  furnished to the person  asserting  the loss,  liability,  claim or
damage at or prior to the time such action is required by the Securities Act.

               (e)  Contribution.  In order to  provide  for just and  equitable
contribution  to joint  liability  under the Securities Act in any case in which
either  (i) the Series A  Preferred  shareholders  or the  Company  (and/or  any
officer,  director,  underwriter  or  controlling  person who may be indemnified
under  Section  1.6(a) or  Section  1.6(b)),  makes a claim for  indemnification
pursuant to this Section 1.6 but it is judicially  determined (by the entry of a
final judgment or decree by a court of competent jurisdiction and the expiration
of time to  appeal  or the  denial  of the  last  right  of  appeal)  that  such
indemnification  may not be enforced in such case  notwithstanding the fact that
this Section 1.6 provides for indemnification in such case, or (ii) contribution
under the  Securities  Act may be required on the part of the Series A Preferred
shareholders  or the  Company  (and/or any  officer,  director,  underwriter  or
controlling  person who may be  indemnified  under Section  1.6(a) or 1.6(b)) in
circumstances  for which  indemnification  is provided  under this  Section 1.6;
then, and in each such case, the Company and the Series A Preferred shareholders
(and/or such other  person) will  contribute to the  aggregate  losses,  claims,
damages or  liabilities to which they may be subject  (after  contribution  from
others)  in  proportion  to their  relative  fault as  determined  by a court of
competent jurisdiction; provided, however, that in no event (i) shall the Series
A Preferred shareholders be responsible for more than the portion represented by
the  percentage  that the public  offering price of the  Registrable  Securities
offered and sold by the Series A Preferred  shareholders  under the registration
statement bears to the public offering price of all securities  offered and sold
under  such  registration  statement  and (ii)  shall  the  Series  A  Preferred
shareholders  be  required  to  contribute  any  amount in excess of the  public
offering price of all such Registrable Securities offered and sold by the Series
A Preferred  shareholders  pursuant to such registration  statement,  and in any
event,  no person or entity 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.


               (f)  Survival.  The  obligations  of the Company and the Series A
Preferred  shareholders  under this Section 1.6 shall survive the  completion of
any  offering  of  Registrable  Securities  in  a  registration  statement,  and
otherwise.

          1.7 Rule 144 Reporting.  With a view to making  available the benefits
of certain rules and regulations of the Commission  which may at any time permit
the sale of the Registrable  Securities to the public without registration,  for
so long as the Series A Preferred shareholders owns any Registrable  Securities,
the Company agrees to:

               (a) Make and keep public  information  available,  as those terms
are


                                                                         Page 10


understood and defined in Rule 144 under the Securities Act, at all times;

               (b) File with the  Commission  in a timely manner all reports and
other documents required of the Company under the 1934 Act; and

               (c) So  long  as the  Series  A  Preferred  shareholders  own any
Registrable  Securities,  to  furnish  to the  Series A  Preferred  shareholders
forthwith  upon request a written  statement by the Company as to its compliance
with the  reporting  requirements  of said Rule 144,  a copy of the most  recent
annual or quarterly report of the Company,  and such other reports and documents
of the Company as the Series A Preferred  shareholders may reasonably request in
availing  itself of any rule or regulation of the  Commission  allowing any such
shareholder to sell any such securities without registration.

          1.8 Termination of the Company's  Obligations.  The Company shall have
no obligations to register Registrable Securities held by the Series A Preferred
shareholders  (i) if all  Registrable  Securities  have been registered and sold
pursuant to registrations  effected  pursuant to this Agreement;  or (ii) to the
extent such Registrable  Securities are eligible for resale pursuant to Rule 144
under the Securities Act.

          1.9 Limitations on Subsequent  Registration Rights. From and after the
date of this Agreement, the Company shall not, without the prior written consent
of the holders of a majority  the Series A Preferred,  enter into any  agreement
with any holder or  prospective  holder of any  securities  of the Company which
would allow such holder or prospective  holder (a) to include such securities in
any registration filed under Section 1.2 or1.3 hereof, unless under the terms of
such agreement, such holder or prospective holder may include such securities in
any such  registration  only to the extent that the inclusion of his  securities
will not  reduce  the  amount  of the  Registrable  Securities  of the  Series A
Preferred  shareholders which is included,  or (b) to make a demand registration
which could result in such registration  statement being declared  effective (i)
during the  effectiveness of any  registration  statement  effected  pursuant to
Section 1.2, or (ii) within one hundred  twenty (120) days of the effective date
of any registration effected pursuant to Section 1.2.

     2. ASSIGNMENT.

          2.1 Assignment.  Notwithstanding  anything herein to the contrary, the
registration  rights of the  Series A  Preferred  shareholders  under  Section 1
hereof may be assigned only to (a) any family member or trust for the benefit of
a Series A  Preferred  shareholder,  (b) any party  who  acquires  ownership  or
control of any Series A Preferred  shareholder through a merger,  consolidation,
sale of assets or similar business combination, (c) any transferree who acquires
not less than 2,500,000 shares of Registrable  Securities,  or (d) any affiliate

assigned any of the foregoing  rights until the Company is given written  notice
by the  assigning  party at the  time of such  assignment  stating  the name and
address of the  assignee and  identifying  the  securities  of the Company as to
which the rights in question are being assigned;  and provided further, that any
such assignee  shall
