         2. Registration.

         2.1 The  Holders  collectively  shall  have the  right to  request  one
registration of Holders' Registrable  Securities for an offering to be made on a
continuous basis pursuant to Rule 415 under the Securities Act. Any such request
shall be made in writing by the Holder or Holders of at least a majority  of the
Registrable  Securities  and  shall  state the  number of shares of  Registrable
Securities  to be disposed of and the intended  methods of  disposition  of such
shares by such Holder or Holders.  Notwithstanding  the  foregoing,  the Company
shall not be obligated to effect any such  registration if the Holder or Holders
requesting such registration propose to sell less than 25% of the Shares. If the
Company is requested in effect a  registration  in accordance  with this Section
2.1,  the  Company  shall   promptly  give  written  notice  of  such  requested
registration  to all Holders (the "Company  Notice"),  who shall be permitted to
join in such requested registration upon written notice (which notice shall also
state the number of shares of  Registrable  Securities to be disposed of and the
intended methods of distribution) to the Company delivered within 10 days of the
date of the Company Notice.

         2.2 The  registrations  provided  for in this  Section  2 shall  not be
underwritten.

         3. Obligations of the Company.

         Whenever  requested  under Section 2.1 of this  Agreement to effect the
registration of any Registrable Securities,  the Company shall, as expeditiously
as reasonably possible:

         3.1 Prepare and file with the Commission a registration  statement with
respect to such  Registrable  Securities and use its reasonable  best efforts to
cause  such  registration   statement  to  become   effective,   and  keep  such
registration statement continuously effective under the Securities Act until the
earlier  of  the  expiration  of 90  days  after  the  date  of  declaration  of
effectiveness of such registration  statement by the Commission (the "Expiration
Date") or the date on which this  Agreement has  terminated  with respect to all
Holders of Registrable Securities. The Company's obligations hereunder to file a
registration  statement  and  to  keep  a  registration  statement  continuously
effective  under the Securities Act shall be suspended if (i) the fulfillment of
such  obligations  would require the Company to make a disclosure that would, in
the reasonable  judgment of the Company's Board of Directors,  be detrimental to
the Company and premature, (ii) the Company has filed or proposes to file within
thirty (30) days after receipt of a request for registration pursuant to Section
2.1 a  registration  statement  with  respect  to any of  its  securities  to be
distributed in an underwritten  public offering and it is advised by its lead or
managing  underwriter  that an  offering  by a Holder or Holders of  Registrable
Shares would materially adversely affect the distribution of such securities, or
(iii) the fulfillment of such  obligations  would require the Company to prepare
financial  statements not required to be prepared for the Company to comply with
its obligations under the Exchange Act. Such obligations shall be reinstated (x)
in the case of clause  (i)  above,  upon the  making of such  disclosure  by the
Company  (or,  if  earlier,  when  such  disclosure  would  either  no longer be
necessary for the fulfillment of such  obligations or no longer be detrimental),
(y) in the case of clause (ii) above,  upon the  conclusion of any period during
which  the  Company  would  not,  pursuant  to the  terms  of  its  underwriting
arrangements,  be permitted to sell  Registrable  Securities for its own account
and (z) in the case of  clause  (iii)  above,  as soon as it would no  longer be
necessary to prepare such  financial  statements  to comply with the  Securities
Act.  The  Expiration  Date shall be tolled for the  duration of any  suspension
pursuant to this  Section 3.1 and for the  duration of any period  described  in
clauses  (i) - (iv) of  Section  4.2  below.  In the  event  that the  Company's
obligations  are  suspended  as  provided  above,  the Company  shall  deliver a
certificate  in  writing,  signed by an officer of the  Company,  to each Holder
participating  in such  registration,  which  shall  state that its  obligations
hereunder have been suspended in accordance  with this Section 3.1 and the basis
for such suspension.

         3.2  Prepare  and  file  with  the  Commission   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.

         3.3 Furnish to the Holders covered by such registration  statement such
numbers  of copies of a  prospectus,  including  a  preliminary  prospectus,  in
conformity with the requirements of the Securities Act, and such other documents
as they may reasonably  request in order to facilitate  the  disposition of such
Registrable Securities.

          3.4 Use its  reasonable  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  thereof,  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.

          4. Obligations of the Holders.

          4.1 It  shall  be a  condition  precedent  to the  obligations  of the
Company to take any action  pursuant to this Agreement that the selling  Holders
shall  furnish  to  the  Company  such  information  regarding  themselves,  the
Registrable  Securities  held by them, and the intended method of disposition of
such  securities  as  shall  be  required  to  effect  the  registration  of the
Registrable Securities.

         4.2 Upon the  receipt by a Holder of any notice from the Company of (i)
the existence of any fact or the happening of any event as a result of which the
prospectus included in a registration  statement filed pursuant to Section 2, as
such registration statement is 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, (ii) the existence of any facts or events resulting
in the  suspension of the  Company's  obligations  to file and keep  effective a
registration  statement as provided in Section 3.1 above,  (iii) the issuance by
the SEC of any stop order or  injunction  suspending or enjoining the use or the
effectiveness  of  such   registration   statement  or  the  initiation  of  any
proceedings  for that  purpose,  or the  taking  of any  similar  action  by the
securities regulators of any state or other jurisdiction, or (iv) the request by
the Commission or any other federal or state governmental  agency for amendments
or  supplements  to such  registration  statement or related  prospectus  or for
additional  information related thereto, such Holder shall forthwith discontinue
disposition of such Holder's Registrable Securities covered by such registration
or  prospectus  (other  than  in  transactions   exempt  from  the  registration
requirements  under the  Securities  Act)  until  such  Holder's  receipt of the
supplemented or amended prospectus or until such Holder is advised in writing by
the Company that the use of the applicable  prospectus may be resumed or, in the
case of a notice pursuant to clause (ii) above, until the Company's  obligations
referred to therein are no longer suspended;  provided, however, that, except in
the  circumstances  described in clause (ii) above,  the Company shall take such
reasonable  actions  as are  necessary  to permit  the  Holders  to  resume  the
disposition of their Registrable Securities at the earliest practicable time.

         5. Expenses.

         The Company shall bear and pay all expenses  incurred by the Company in
connection  with  any  registration,  filing  or  qualification  of  Registrable
Securities  with  respect to any  registration  pursuant to Section 2 hereof for
each Holder thereof, including (without limitation) all registration, filing and
qualification  fees,  printers' and  accounting  fees relating or  apportionable
thereto,  fees and  disbursements of counsel for the Company,  blue sky fees and
expenses,  including fees and  disbursements  of counsel related to all blue sky
matters,  but  excluding the fees and  disbursements  of counsel for the selling
Holders,  stock transfer taxes that may be payable by the selling  Holders,  and
all brokerage or similar commissions relating to Registrable  Securities,  which
shall be borne by the selling Holders.

         6. Indemnification.

         In the event any Registrable  Securities are included in a registration
statement under this Agreement:

         6.1 To the extent permitted by law, the Company will indemnify and hold
harmless each Holder of such Registrable Securities and each person, if any, who
controls  such Holder within the meaning of the  Securities  Act or the Exchange
Act, against any losses,  claims,  damages or liabilities  (joint or several) to
which they may become  subject  under the  Securities  Act,  the Exchange 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  such  registration  statement,  including  any  preliminary
prospectus  or  final  prospectus   contained   therein  or  any  amendments  or
supplements  thereto,  (ii) the omission or alleged  omission to state therein a
material fact required to be stated therein, or necessary to make the statements
therein not  misleading,  or (iii) any  violation  or alleged  violation  by the
Company of the Securities Act, the Exchange Act, any state securities law or any
rule or regulation promulgated under the Securities Act, the Exchange Act or any
state  securities  law;  and the  Company  will  reimburse  each such  Holder or
controlling person for any legal or other expenses  reasonably  incurred by them
in connection  with  investigating  or defending any such 1088,  claim,  damage,
liability or action;  provided,  however, that the indemnity agreement contained
in this  Section 6.1 shall not apply to amounts paid in  settlement  of any such
1088, 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  1088,  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  written
information  furnished expressly for use in connection with such registration by
any such Holder or controlling person.

          6.2 To the extent permitted by law, each selling Holder will indemnify
and hold harmless the Company,  each of its directors,  each of its officers who
have signed the registration  statement,  each person,  if any, who controls the
Company within the meaning of the  Securities  Act, and any other Holder selling
securities in such registration statement or any of its directors or officers or
any person who controls  such  Holder,  against any losses,  claims,  damages or
liabilities  (joint or  several)  to which  the  Company  or Any such  director,
officer or  controlling  person,  or other such Holder or  director,  officer or
controlling  person may become  subject,  under the Securities Act, the Exchange
Act or other federal or state law,  insofar as such losses,  claims,  damages or
liabilities  (or actions in respect  thereto) arise out of or are based upon any
Violation,  in each  case to the  extent  (and  only to the  extent)  that  such
Violation  occurs in reliance  upon and in conformity  with written  information
furnished by such Holder expressly for use in connection with such registration;
and each such  Holder  will  reimburse  any legal or other  expenses  reasonably
incurred  by the  Company or any such  director,  officer,  controlling  person,
underwriter  or  controlling  person,  other  Holders  officer,   director,   or
controlling  person in connection with investigating or defending any such loss,
claim,  damage,  liability,  or action;  provided,  however,  that the indemnity
agreement  contained  in this  Section  6.2 shall not apply to  amounts  paid in
settlement  of any  such  1088,  claim,  damage,  liability  or  nation  if such
settlement  is effected  without the consent of the Holder,  which consent shall
not be  unreasonably  withheld;  provided,  that in no event shall any indemnity
under this  Section 6.2 exceed the gross  proceeds  received by such Holder from
the sale of Registrable Securities as contemplated hereunder.

         6.3 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 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 80
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  retrain  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  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 Ouch
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.

         6.4 The  obligations  of the Company and Holders  under this  Section 6
shall  survive the  completion  of any offering of  Registrable  Securities in a
registration statement under this Agreement, and otherwise.

         7. Termination of Registration Rights.

          The Company's  obligations  pursuant to this Agreement shall terminate
as to any Holder of  Registrable  Securities on the earlier of (i) the date when
the Holder can sell all of such Holder's  shares  pursuant to Rule 144 under the
Securities Act during any 90-day period or (ii) on the second anniversary of the
date hereof.

         8. Representations and Warranties of the Company.

         The Company hereby represents and warrants to Yochim and Keenan that:

         8.1 When  issued in  accordance  with the terms and  conditions  of the
Exchange  Agreement,   the  Shares  will  be  validly  issued,  fully  paid  and
non-assessable.

         8.2 The  Company is current in making all filings  with the  Commission
required by law, and in the last 12 months, on a timely basis, has made all such
filings,  and as of the date hereof is  eligible  to register  the resale of the
Shares by the Holders on Form S-3.
