      Registration.

with  the  Commission  a  Registration  Statement  covering  the  resale  of all
Registrable  Securities  not  already  covered  by  an  existing  and  effective
Registration Statement for an offering to be made on a continuous basis pursuant
to Rule 415.  The  Registration  Statement  shall be on Form S-3  (except if the
Company is not then eligible to register for resale the  Registrable  Securities
on Form S-3,  in which case such  registration  shall be on another  appropriate
form for such purpose) and shall contain (subject to such modification as may be
required  pursuant to written comments received from the staff of the Commission
upon a  review  of such  Registration  Statement)  the  "Plan  of  Distribution"
attached hereto as Annex A. The Company shall use its reasonable best efforts to
cause the Registration  Statement to be declared  effective under the Securities
Act as soon as possible but, in any event, no later than the Effectiveness Date,
and shall use its  reasonable  best efforts to keep the  Registration  Statement
continuously  effective  under the  Securities  Act until the date  which is two
years after the date that the  Registration  Statement is declared  effective by
the Commission or such earlier date when all Registrable  Securities  covered by
the Registration Statement have been sold or may be sold without volume or other
restrictions pursuant to Rule 144(k) as determined by the counsel to the Company
pursuant to a written opinion letter to such effect, addressed and acceptable to
the  Company's  transfer  agent and the  affected  Holders  (the  "Effectiveness
Period"). It is agreed and understood that the Company shall, from time to time,
be  obligated  to  file  an  additional  Registration  Statement  to  cover  any
Registrable  Securities  which  are not  registered  for  resale  pursuant  to a
pre-existing  Registration  Statement (e.g.,  following the receipt of a request
from a Holder,  whose  Registrable  Securities are not so registered for resale,
that the Holder's Registrable Securities be registered for resale).

            If:  (i) a  Registration  Statement  is not filed on or prior to its
Filing Date (if the Company files a Registration Statement without affording the
Holders the opportunity to review and comment on the same as required by Section
3(a) hereof, the Company shall not be deemed to have satisfied this clause (i)),
or (ii) a Registration  Statement is not declared effective by the Commission on
or prior to its required  Effectiveness Date, or (iii) after its Effective Date,
such  Registration  Statement or related  Prospectus ceases for any reason to be
available to the Holders as to all Registrable  Securities the offer and sale of
which  it is  required  to cover at any  time  prior  to the  expiration  of its
Effectiveness Period (whether due to the Registration  Statement ceasing for any
reason to be effective or because use of the  Prospectus  has been suspended for
any reason, including, without limitation,  pursuant to Section 3(j) hereof) for
an  aggregate  of more than 20  consecutive  Trading  Days or an aggregate of 40
Trading  Days (which need not be  consecutive)  in any twelve  month period (any
such  failure or breach  being  referred to as an "Event,"  and for  purposes of
clauses  (i) or (ii) the date on which such Event  occurs,  or for  purposes  of
clause (iii) the date which such 20  consecutive  or 40 Trading  Day-period  (as
applicable) is exceeded,  being referred to as "Event Date"),  then, in addition
to any other rights available to the Holders: (x) on such Event Date the Company
shall pay to each Holder an amount in cash, as  liquidated  damages and not as a
penalty, equal to 1% of the aggregate purchase price paid by such Holder for its
Shares pursuant to the Purchase  Agreement;  and (y) on each monthly anniversary
of each such Event Date  thereof  (if the  applicable  Event shall not have been
cured by such date, subject to pro rata payment pursuant to the last sentence of
this Section 2(b)) until the applicable Event is cured, the Company shall pay to
each Holder an additional  amount in cash,  as  liquidated  damages and not as a
penalty,  equal to 1.5% of the  aggregate  purchase  price  paid by such  Holder
pursuant to the Purchase Agreement,  provided, that all periods shall be tolled,
with  respect to a Holder,  by the number of Trading  Days in excess of ten (10)
during which such Holder fails to provide the Company with information regarding
such  Holder  and the  Registrable  Securities  held by such  Holder  which  was
reasonably  requested by the Company in order to effect the registration of such
Holder's Registrable  Securities  (provided further,  that in the event that the
Commission's  staff takes the  position in written  comments to the Company that
such  failure  precludes  such staff from  declaring  a  Registration  Statement

                                       3


effective,  then such  Holder's  Registrable  Securities  may be excluded by the
Company from such Registration Statement).  It shall be a condition precedent to
the  obligations of the Company to pay any liquidated  damages  pursuant to this
Section 2 with  respect to the  Registrable  Securities  of any Holder that such
Holder shall furnish to the Company such  information  regarding  itself and the
Registrable  Securities  held by it. If the Company fails to pay any  liquidated
damages  pursuant  to this  Section  in full  within  seven  days after the date
payable, the Company will pay interest thereon at a rate of 12% per annum (or if
the maximum  amount that is permitted to be paid by  applicable  law is a lesser
amount,  such lesser  amount) to the Holder,  accruing  daily from the date such
liquidated  damages are due until such amounts,  plus all such interest thereon,
are paid in full.  The  liquidated  damages  pursuant to the terms  hereof shall
apply on a pro rata  basis for any  portion  of a month  prior to the cure of an
Event.  Notwithstanding the foregoing, after such time as the Company shall have
become  obligated  pursuant to this Section 3(b) to any Holder to make  payments
(and  shall  have made  such  payments)  in the  aggregate  (excluding  for such
purposes payments of any interest  thereon) of 5.0% of the aggregate  Investment
Amount paid by such Holder for Shares pursuant to the Purchase  Agreement,  then
the amount of liquidated  damages to be calculated in accordance  with the above
sentences shall thereafter for such Holder be reduced from 1.0% to 0.5% and from
1.5% to 1.0%,  respectively,  with respect to all such liquidated damages (other
than  with  respect  to  interest  thereon)  accruing  in  excess of 5.0% of the
aggregate Investment Amount paid by such Holder for such Shares.

      Registration Procedures

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

                  (i) Not less than five (5) Trading Days prior to the filing of
a  Registration  Statement  or  any  related  Prospectus  or  any  amendment  or
supplement thereto, furnish to the Holders copies of all such documents proposed
to be filed which documents (other than those incorporated by reference) will be
subject to the review of such Holders. The Company shall not file a Registration
Statement or any such  Prospectus or any  amendments or  supplements  thereto to
which the Holders of a majority of the Registrable  Securities  shall reasonably
object  in  writing  in good  faith  unless  and until the  Company  shall  have
reasonably responded to the written comments of such Holders, including, without
limitation, by making such changes to such Registration Statement or any related
Prospectus or any amendment thereto as are necessary to reasonably  address such
objection.

                                       4


                  (ii) (A) Prepare and file with the Commission such amendments,
including  post-effective  amendments,  to each  Registration  Statement and the
Prospectus  used in  connection  therewith  as may be necessary to (x) keep such
Registration  Statement  continuously effective as to the applicable Registrable
Securities  for its  Effectiveness  Period,  and  (y)  include  any  Registrable
Securities  held by any person who becomes a successor  or assign of a Holder (a
"Successor  Holder") in  accordance  with Section 6(e) hereof and Section 6.6 of
the Purchase  Agreement;  such amendment shall be filed promptly after notice of
transfer by a Holder to such  Successor  Holder has been provided to the Company
(provided,  that if the inclusion of Registrable  Securities held by a Successor
Holder may be accomplished by a Prospectus supplement,  the Company may, in lieu
of filing an amendment to the Registration Statement,  promptly prepare and file
pursuant  to Rule  424  such  Prospectus  supplement);  (B)  cause  the  related
Prospectus to be amended or supplemented by any required Prospectus  supplement,
and as so  supplemented or amended to be filed pursuant to Rule 424; (C) respond
as promptly as reasonably possible, and in any event within ten Trading Days, to
any comments  received  from the  Commission  with respect to each  Registration
Statement  or any  amendment  thereto  and, as promptly as  reasonably  possible
provide the Holders true and complete copies of all  correspondence  from and to
the  Commission  relating to such  Registration  Statement  that pertains to the
Holders as Selling  Stockholders  but not any comments  that would result in the
disclosure to the Holders of material and non-public  information concerning the
Company;  (D) prepare and file with the Commission such additional  Registration
Statements in order to register for resale under the  Securities  Act all of the
Registrable  Securities;  and (E)  comply  in all  material  respects  with  the
provisions  of the  Securities  Act and the  Exchange  Act with  respect to each
Registration Statement and the disposition of all Registrable Securities covered
by each Registration Statement.

                  (iii)  Notify the Holders in writing no later than two Trading
Days following the day (A)(x) when the Commission  notifies the Company  whether
there  will be a  "review"  of such  Registration  Statement  and  whenever  the
Commission comments in writing on such Registration Statement (the Company shall
provide to each of the Holders true and complete  copies thereof and all written
responses thereto that pertain to the Holders as Selling  Stockholders or to the
Plan of Distribution,  but not information which the Company reasonably believes
would constitute material and non-public  information);  and (y) with respect to
each Registration Statement or any post-effective  amendment,  when the same has
become  effective;  (B) of any request by the Commission or any other Federal or
state  governmental  authority for  amendments or  supplements to a Registration
Statement or  Prospectus  or for  additional  information  that  pertains to the
Holders as Selling Stockholders or the Plan of Distribution; (C) of the issuance
by  the  Commission  of  any  stop  order  suspending  the  effectiveness  of  a
Registration  Statement covering any or all of the Registrable Securities or the
initiation  of any  Proceedings  for that  purpose;  (D) of the  receipt  by the
Company of any notification  with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Securities for sale in
any  jurisdiction,  or the  initiation or threatening of any Proceeding for such
purpose;  and (E) subject to Section  3(b),  of the  occurrence  of any event or
passage of time that makes the financial  statements  included in a Registration
Statement  ineligible  for  inclusion  therein  or any  statement  made  in such
Registration  Statement or Prospectus or any document  incorporated or deemed to
be  incorporated  therein by reference  untrue in any  material  respect or that
requires  any  revisions to such  Registration  Statement,  Prospectus  or other
documents so that, in the case of such Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue  statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

                                       5


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

                  (v)  Furnish  to each  Holder,  without  charge,  at least one
conformed copy of each Registration Statement and each amendment thereto and all
exhibits to the extent  requested  by such Person  (including  those  previously
furnished  or  incorporated  by  reference)  promptly  after the  filing of such
documents with the Commission.

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

                  (vii) Prior to any public offering of Registrable  Securities,
use its  reasonable  best efforts to register or qualify or  cooperate  with the
selling  Holders  in  connection  with the  registration  or  qualification  (or
exemption  from  such   registration  or   qualification)  of  such  Registrable
Securities  for offer and sale  under the  securities  or Blue Sky laws of those
jurisdictions  within the United  States  identified  by each  Purchaser on such
Purchaser's  signature  page to the Purchase  Agreement,  and thereafter to keep
each such  registration  or  qualification  (or exemption  therefrom)  effective
during  the  Effectiveness  Period,  and to do any and all other  acts or things
necessary or advisable to enable the  disposition in such  jurisdictions  of the
Registrable Securities covered by the Registration  Statements;  provided,  that
the Company shall not be required to qualify  generally to do business or file a
general consent to service of process in any  jurisdiction  where it is not then
so qualified or subject the Company to any material tax in any such jurisdiction
where it is not then so subject .

                  (viii)  Cooperate  with the Holders to  facilitate  the timely
preparation and delivery of certificates  representing Registrable Securities to
be  delivered  to a purchaser  pursuant to the  Registration  Statements,  which
certificates  shall  be free of all  restrictive  legends,  and to  enable  such
Registrable  Securities to be in such denominations and registered in such names
as any such Holders may request.

                  (ix) Upon the occurrence of any event  contemplated by Section
3(a)(iii)(E),  as promptly  as  reasonably  possible,  prepare a  supplement  or
amendment,  including a post-effective  amendment,  to the affected Registration
Statements  or  a  supplement   to  the  related   Prospectus  or  any  document
incorporated  or deemed to be  incorporated  therein by reference,  and file any
other  required  document so that,  as  thereafter  delivered,  no  Registration
Statement nor any Prospectus will contain an untrue statement of a material fact
or omit to state a material fact  required to be stated  therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading.

                                       6

hereunder, the Company may require each selling Holder to furnish to the Company
a certified  statement as to the number of shares of Common  Stock  beneficially

for  such  Holder  which  the  Commission   requires  to  be  disclosed  in  any
Registration Statements. For not more than twenty (20) consecutive days or for a
total of not more than  forty (40) days in any twelve  (12)  month  period,  the
Company  may  suspend the use of any  Prospectus  included  in any  Registration

3(a)(iii)(B)-(E) (an "Allowed Delay"); provided, that the Company shall promptly
(a) notify the Holders in writing of the existence of (but in no event,  without
the prior written consent of a Holder, shall the Company disclose to such Holder
any of the facts or circumstances  regarding)  material  non-public  information
giving rise to an Allowed Delay,  (b) advise the Holders in writing to cease all
sales under the  Registration  Statement  until the end of the Allowed Delay and

practicable.  The periods set forth in Section  2(b) shall not be tolled  during
any Allowed Delay.

necessary  to make the  statements  therein  (in the case of any  Prospectus  or
supplement  thereto,  in light of the circumstances  under which they were made)
not  misleading,  except to the  extent,  but only to the  extent  (1) that such
untrue statements or omissions are based solely upon information  regarding such
Holder  furnished  in writing to the  Company by such Holder  expressly  for use
therein,  or to the extent that such information  relates to such Holder or such
Holder's  proposed  method of  distribution  of  Registrable  Securities and was

Holder  fails to  deliver,  within the time  required by the  Securities  Act, a
Prospectus  that is  amended or  supplemented,  to the  extent,  but only to the
extent, that such Prospectus,  as amended or supplemented,  would have corrected
the untrue  statement or omission or alleged  untrue  statement or omission of a
material fact giving rise to such Loss contained in the Prospectus  delivered by
such Holder,  so long as the Prospectus,  as amended or  supplemented,  has been
delivered  to such  Holder by the  Company  reasonably  prior to such time.  The

assertion of any Proceeding of which the Company is aware in connection with the

or based solely upon:  any untrue  statement of a material fact contained in any
Registration  Statement,  any  Prospectus,  or in any  amendment  or  supplement
thereto,  or  arising  solely  out of or based  solely  upon any  omission  of a
material fact required to be stated  therein or necessary to make the statements
therein (in the case of any  Prospectus or supplement  thereto,  in light of the
circumstances under which they were made) not misleading to the extent, but only
to the extent (1) that such untrue statements or omissions are based solely upon
information  regarding  such Holder  furnished in writing to the Company by such
Holder expressly for use therein, or to the extent that such information relates
to such Holder or such Holder's  proposed  method of distribution of Registrable
Securities  and was  reviewed and  expressly  approved in writing by such Holder
expressly for use in the  Registration  Statement (it being understood that each

                                       8


Holder has approved Annex A hereto for this purpose),  such Prospectus or in any
amendment  or  supplement  thereto,  (2)  arising  from  any  offer  or  sale of
Registrable Securities during a period in which the Company has suspended use of
the Prospectus  pursuant to Section  3(c)(ii)-(v)  and of which  suspension such
Holder has been  provided  notice by the Company prior to such offer or sale, or
(3) if such Holder fails to deliver,  within the time required by the Securities
Act, a Prospectus that is amended or supplemented,  to the extent, but solely to
the  extent,  that such  Prospectus,  as  amended  or  supplemented,  would have
corrected  the untrue  statement  or omission  or alleged  untrue  statement  or
omission of a material fact giving rise to such Loss contained in the Prospectus
delivered by such Holder, so long as the Prospectus, as amended or supplemented,
has been delivered to such Holder by the Company  reasonably prior to such time.
In no event shall the  liability of any selling  Holder  hereunder be greater in
amount than the dollar  amount of the net proceeds  received by such Holder upon
the  sale of the  Registrable  Securities  giving  rise to such  indemnification
obligation.

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

            An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense  thereof,  but the fees
and expenses of such counsel shall be at the expense of such  Indemnified  Party
or Parties unless:  (1) the Indemnifying Party has agreed in writing to pay such
fees and  expenses;  (2) the  Indemnifying  Party shall have failed  promptly to
assume  the  defense  of  such  Proceeding  and  to  employ  counsel  reasonably
satisfactory to such Indemnified Party in any such Proceeding;  or (3) the named
parties to any such Proceeding  (including any impleaded  parties)  include both
such Indemnified  Party and the Indemnifying  Party, and such Indemnified  Party
shall have been  advised by counsel  that a conflict  of  interest  is likely to
exist if the same  counsel  were to  represent  such  Indemnified  Party and the
Indemnifying  Party (in which  case,  if such  Indemnified  Party  notifies  the
Indemnifying  Party in writing that it elects to employ separate  counsel at the
expense of the Indemnifying  Party,  the  Indemnifying  Party shall not have the
right to assume the defense  thereof and such counsel shall be at the expense of
the Indemnifying  Party),  provided,  that the  Indemnifying  Party shall not be
liable for the fees and expenses of more than one separate firm of attorneys (in
addition  to  local  counsel)  at any  time  for all  Indemnified  Parties.  The
Indemnifying Party shall not be liable for any settlement of any such Proceeding
effected  without its written  consent,  which consent shall not be unreasonably
withheld.  No Indemnifying Party shall, without the prior written consent of the
Indemnified Party, effect any settlement of any pending Proceeding in respect of
which  any  Indemnified  Party  is or  could  have  been a  party,  unless  such
settlement includes an unconditional  release of such Indemnified Party from all
liability on claims that are the subject matter of such Proceeding.

                                       9


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

            Contribution.  If a claim for indemnification  under Section 5(a) or
5(b) is  unavailable  to an  Indemnified  Party (by  reason of public  policy or
otherwise),   then  each  Indemnifying  Party,  in  lieu  of  indemnifying  such
Indemnified  Party,  shall  contribute  to the  amount  paid or  payable by such
Indemnified  Party  as a  result  of  such  Losses,  in  such  proportion  as is
appropriate  to  reflect  the  relative  fault  of the  Indemnifying  Party  and
Indemnified  Party in connection with the actions,  statements or omissions that
resulted in such Losses as well as any other relevant equitable  considerations.
The relative fault of such  Indemnifying  Party and  Indemnified  Party shall be
determined by reference to, among other things,  whether any action in question,
including any untrue or alleged untrue  statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to
information  supplied by, such Indemnifying  Party or Indemnified Party, and the
parties'  relative intent,  knowledge,  access to information and opportunity to
correct or prevent such action, statement or omission.

            The parties  hereto agree that it would not be just and equitable if
contribution  pursuant  to  this  Section  5(d)  were  determined  by  pro  rata
allocation or by any other method of allocation  that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 5(d), no Holder shall be required
to contribute, in the aggregate, any amount in excess of the amount by which the
proceeds  actually  received  by such  Holder  from the sale of the  Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has  otherwise  been  required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission.

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

      Miscellaneous

            Remedies. In the event of a breach by the Company or by a Holder, of
any of their  obligations under this Agreement,  each Holder or the Company,  as
the case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled to
specific  performance of its rights under this  Agreement.  The Company and each
Holder agree that monetary damages would not provide  adequate  compensation for
any losses incurred by reason of a breach by it of any of the provisions of this
Agreement  and  hereby  further  agrees  that,  in the event of any  action  for
specific  performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

                                       10


            No  Piggyback on  Registrations.  Neither the Company nor any of its
security  holders (other than the Purchasers in such capacity  pursuant  hereto)
may include  securities of the Company in the Registration  Statement other than
the Registrable Securities,  and the Company shall not after the date hereof and
until the Registration Statement is declared effective, enter into any agreement
providing any such right to any of its security holders. Except pursuant to that
certain  Registration Rights Agreement dated September 29, 2004 by and among the
Company  and the other  signatories  thereto,  the  Company  has not  previously
entered into any agreement granting any registration  rights with respect to any
of its securities to any Person which have not been fully satisfied.

            Purchasers'  Piggy-Back  Registrations.  If at any  time  after  the
Filing Date and prior to the expiration of the Effectiveness Period there is not
an effective  Registration  Statement covering all of the Registrable Securities
and the Company  shall  determine  to prepare and file,  or has filed,  with the
Commission a registration  statement relating to an offering for its own account
or the  account  of  others  under  the  Securities  Act  of  any of its  equity
securities,  other than (i) on Form S-4 or Form S-8 (each as  promulgated  under
the Securities Act) or their then equivalents  relating to equity  securities to
be issued solely in connection with any acquisition of any entity or business or
equity  securities  issuable in connection  with stock option or other  employee
benefit plans or (ii) on Form S-3 (as  promulgated  under the Securities Act) or
its then  equivalent  relating  to  equity  securities  to be  issued  solely in
connection  with the Company's  dividend  reinvestment  and stock purchase plan,
then the Company shall send to each Holder written notice of such  determination
and, if within fifteen days after receipt of such notice,  any such Holder shall
so request in writing, the Company shall include in such registration  statement
all or any  part of such  Registrable  Securities  such  Holder  requests  to be
registered,  subject to customary underwriter cutbacks applicable to all holders
of registration rights.

            Amendments and Waivers. No provision of this Agreement may be waived
or amended except in a written  instrument  signed by the Company and the Holder
or Holders (as  applicable)  of no less than a majority of the then  outstanding
Registrable Securities.  No waiver of any default with respect to any provision,
condition or requirement  of this  Agreement  shall be deemed to be a continuing
waiver in the  future or a waiver of any  subsequent  default or a waiver of any
other  provision,  condition  or  requirement  hereof,  nor  shall  any delay or
omission of either  party to exercise any right  hereunder in any manner  impair
the exercise of any such right.

            Notices.  Any and all notices or other  communications or deliveries
required or permitted to be provided  hereunder shall be in writing and shall be
deemed given and effective on the earliest of (i) the date of  transmission,  if
such notice or  communication is delivered via facsimile at the facsimile number
specified in this Section  prior to 5:00 p.m.  (New York time) on a Business Day
and  confirmation of such delivery is received,  (ii) the Business Day after the
date of transmission, if such notice or communication is delivered via facsimile
at the facsimile  telephone  number  specified in this Agreement later than 5:00
p.m.  (New  York  time) on the date of  transmission  and  confirmation  of such
delivery is received, (iii) the Business Day following the date of transmission,
if sent by nationally  recognized overnight courier service, or (iv) upon actual
receipt by the party to whom such notice is  required  to be given.  The address
for such notices and communications shall be as follows:

      If to any other Person who is then the registered Holder:

                              stock transfer books of the Company

or such other  address as may be designated  in writing  hereafter,  in the same
manner, by such Person.

            Successors and Assigns. This Agreement shall inure to the benefit of
and be binding upon the successors and permitted  assigns of each of the parties
and shall  inure to the benefit of each  Holder.  The Company may not assign its
rights or  obligations  hereunder  without  the prior  written  consent  of each
Holder,  except to any surviving or successor  corporation in connection  with a
merger or  consolidation of the Company with another  corporation,  after notice
duly given by the  Company  in writing to each  Holder at least 20 days prior to
the  consummation  of such  transaction.  Each Holder may assign  such  Holder's
rights  hereunder  in the  manner  and to the  Persons  as  permitted  under the
Purchase Agreement

            Execution and  Counterparts.  This  Agreement may be executed in any
number of counterparts,  each of which when so executed shall be deemed to be an
original  and, all of which taken  together  shall  constitute  one and the same
Agreement.   In  the  event  that  any   signature  is  delivered  by  facsimile
transmission,  such  signature  shall create a valid  binding  obligation of the
party  executing  (or on whose behalf such  signature is executed) the same with
the same  force and  effect as if such  facsimile  signature  were the  original
thereof.

            Governing Law. All questions concerning the construction,  validity,
enforcement  and  interpretation  of this  Agreement  shall be  governed  by and
construed and enforced in accordance  with the internal laws of the State of New
York,  without regard to the principles of conflicts of law thereof.  Each party
agrees that all  Proceedings  concerning  the  interpretation,  enforcement  and
defense of the  transactions  contemplated  by this Agreement  (whether  brought
against a party hereto or its respective Affiliates, employees or agents) may be
commenced in the state and federal  courts sitting in the State of New York (the

                                       12


"New  York  Courts").  Each  party  hereto  hereby  irrevocably  submits  to the
non-exclusive  jurisdiction  of the New York Courts for the  adjudication of any
dispute hereunder or in connection herewith or with any transaction contemplated
hereby or discussed herein,  and hereby  irrevocably  waives,  and agrees not to
assert in any  Proceeding,  any claim that it is not  personally  subject to the
jurisdiction  of any New York Court,  or that such Proceeding has been commenced
in an improper or  inconvenient  forum.  Each party  hereto  hereby  irrevocably
waives  personal  service of process and consents to process being served in any
such  Proceeding by mailing a copy thereof via  registered or certified  mail or
overnight  delivery  (with evidence of delivery) to such party at the address in
effect for notices to it under this Agreement and agrees that such service shall
constitute good and sufficient  service of process and notice  thereof.  Nothing
contained  herein shall be deemed to limit in any way any right to serve process
in any manner permitted by law. Each party hereto hereby irrevocably  waives, to
the fullest  extent  permitted by applicable  law, any and all right to trial by
jury in any  Proceeding  arising  out of or relating  to this  Agreement  or the
transactions contemplated hereby. If either party shall commence a Proceeding to
enforce any  provisions of this  Agreement,  then the  prevailing  party in such
Proceeding  shall be reimbursed by the other party for its  attorney's  fees and
other  costs and  expenses  incurred  with the  investigation,  preparation  and
prosecution of such Proceeding.

            Cumulative Remedies. The remedies provided herein are cumulative and
not exclusive of any remedies provided by law.

            Severability.  If any term,  provision,  covenant or  restriction of
this  Agreement  is held by a court of  competent  jurisdiction  to be  invalid,
illegal,  void  or  unenforceable,  the  remainder  of  the  terms,  provisions,
covenants  and  restrictions  set forth  herein  shall  remain in full force and
effect and shall in no way be affected, impaired or invalidated, and the parties
hereto  shall use their  reasonable  efforts to find and  employ an  alternative
means to achieve the same or substantially  the same result as that contemplated
by such term,  provision,  covenant or restriction.  It is hereby stipulated and
declared to be the  intention of the parties  that they would have  executed the
remaining terms, provisions, covenants and restrictions without including any of
such that may be hereafter declared invalid, illegal, void or unenforceable.

            Headings.  The headings in this  Agreement  are for  convenience  of
reference only and shall not limit or otherwise affect the meaning hereof.

            Independent   Nature  of  Holders'   Obligations  and  Rights.   The
obligations  of each  Holder  hereunder  is  several  and  not  joint  with  the
obligations of any other Holder hereunder, and no Holder shall be responsible in
any way for the  performance of the  obligations of any other Holder  hereunder.
Nothing contained herein or in any other agreement or document  delivered at any
closing, and no action taken by any Holder pursuant hereto or thereto,  shall be
deemed to  constitute  the Holders as a  partnership,  an  association,  a joint
venture or any other kind of entity,  or create a  presumption  that the Holders
are in any way  acting  in  concert  with  respect  to such  obligations  or the
transactions  contemplated by this Agreement.  Each Holder  acknowledges that no
other  Holder  has  acted  as agent  for  such  Holder  in  connection  with the
investment contemplated by the Purchase Agreement and this Agreement and that no
Holder will be acting as agent of such Holder in connection  with monitoring its
investment  in  the  Shares  or  enforcing  its  rights  under  the  Transaction
Documents.  Each  Holder  shall be  entitled  to protect and enforce its rights,
including  without  limitation the rights arising out of this Agreement,  and it
shall not be necessary for any other Holder to be joined as an additional  party
in any proceeding for such purpose.

                              PLAN OF DISTRIBUTION

      The Selling Stockholders and any of their pledgees,  donees, assignees and
successors-in-interest  may, from time to time,  sell any or all of their shares
of common stock on any stock exchange,  market or trading  facility on which the
shares  are traded or in private  transactions.  These  sales may be at fixed or
negotiated  prices.  The  Selling  Stockholders  may  use any one or more of the
following methods when selling shares:

o     ordinary   brokerage   transactions   and   transactions   in  which   the
      broker-dealer solicits purchasers;

o     block trades in which the broker-dealer will attempt to sell the shares as
      agent but may  position  and resell a portion of the block as principal to
      facilitate the transaction;

o     purchases by a broker-dealer as principal and resale by the  broker-dealer
      for its account;

o     an exchange  distribution  in accordance  with the rules of the applicable
      exchange;

o     privately negotiated transactions;

o     short sales;

o     sales  by  broker-dealers  pursuant  to  an  agreement  with  the  Selling
      Stockholders  to sell a specified  number of such  shares at a  stipulated
      price per share;

o     a combination of any such methods of sale; and

o     any other method permitted pursuant to applicable law.

      The Selling  Stockholders  may also sell  shares  under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

      Broker-dealers  engaged by the Selling  Stockholders may arrange for other
brokers-dealers to participate in sales.  Broker-dealers may receive commissions
or discounts from the Selling  Stockholders  (or, if any  broker-dealer  acts as
agent  for the  purchaser  of  shares,  from the  purchaser)  in  amounts  to be
negotiated.  The  Selling  Stockholders  do not  expect  these  commissions  and
discounts to exceed what is customary in the types of transactions involved.

      The Selling  Stockholders may from time to time pledge or grant a security
interest in some or all of the shares of Common Stock owned by them and, if they
default in the performance of their secured obligations, the pledgees or secured
parties may offer and sell  shares of Common  Stock from time to time under this
prospectus,  or under an amendment or supplement to this prospectus amending the
list of  Selling  Stockholders  to  include  the  pledgee,  transferee  or other
successors in interest as Selling Stockholders under this prospectus.


      Upon the Company being notified in writing by a Selling  Stockholder  that
any material arrangement has been entered into with a broker-dealer for the sale
of shares of common stock  through a block  trade,  special  offering,  exchange
distribution  or  secondary  distribution  or purchase by a broker or dealer,  a
supplement to this  prospectus  will be filed,  if required,  disclosing (i) the
name of each such Selling Stockholder and of the participating broker-dealer(s),
(ii) the number of shares  involved,  (iii) the price at which  such  shares are
sold,  (iv) the  commissions  paid or discounts or  concessions  allowed to such
broker-dealer(s),  where  applicable,  (v) that  such  broker-dealer(s)  did not
conduct any  investigation  to verify the information set out or incorporated by
reference in this prospectus,  and (vi) other facts material to the transaction.
In addition, upon the Company being notified in writing by a Selling Stockholder
that a donee or pledge  intends to sell more than 500 shares of common stock,  a
supplement to this  prospectus will be filed if then required in accordance with
applicable securities law.

      The Selling  Stockholders  also may transfer the shares of common stock in
other circumstances, in which case the transferees, pledgees or other successors
in  interest  will  be the  selling  beneficial  owners  for  purposes  of  this
prospectus.

      The  Selling  Stockholders  and any  broker-dealers  or  agents  that  are
involved  in selling  the shares may be deemed to be  "underwriters"  within the
meaning of the Securities Act in connection with such sales. In such event,  any
commissions  received  by such  broker-dealers  or agents  and any profit on the
resale  of the  shares  purchased  by  them  may be  deemed  to be  underwriting
commissions or discounts under the Securities Act. Each Selling  Stockholder has
represented  and warranted to the Company that it does not have any agreement or
understanding,  directly or indirectly, with any person to distribute the shares
of common stock.

      The Company has advised the Selling Stockholders that they are required to
comply with Regulation M promulgated  under the Exchange Act during such time as
they may be engaged in a  distribution  of the shares.  The foregoing may affect
the marketability of the common stock.

      The  Company is  required  to pay all fees and  expenses  incident  to the
registration  of the shares.  The Company  has agreed to  indemnify  the Selling
Stockholders against certain losses, claims, damages and liabilities,  including
liabilities under the Securities Act.
