                  would permit or facilitate the sale and distribution of all or
                  such portion of such  Registrable  Securities as are specified
                  in such  request,  together  with all or such  portion  of the

                  within thirty (30) days after  receipt of such written  notice
                  from the  Company;  provided,  that the  Company  shall not be
                  obligated to effect, or to take any action to effect, any such
                  registration pursuant to this Section 2:

                                    (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, qualification or compliance, unless the
                           Company  is  already   subject  to  service  in  such
                           jurisdiction  and  except as may be  required  by the
                           Securities  Act or  applicable  rules or  regulations
                           thereunder;

                           after the  effective  date of any other  registration
                           declared   or   ordered   effective   other   than  a
                           registration on Form S-3 or Form S-8;

                                    (iii) if,  while a  registration  request is
                           pending  pursuant  to this  Section  2,  the  Company
                           determines,  in the good faith  judgment of the Board
                           of  Directors  of the  Company,  with the  advice  of
                           counsel, that the filing of a registration  statement
                           would require the  disclosure of non-public  material
                           information  the  disclosure  of which  would  have a
                           material  adverse  effect  on the  Company  or  would
                           otherwise  materially  adversely  affect a financing,
                           acquisition, disposition, merger or other significant

                                       3


                           transaction  involving the Company, the Company shall
                           deliver a  certificate  to such effect  signed by its
                           President  to the  proposed  selling  Holders and the
                           Company   shall   not  be   required   to   effect  a
                           registration  pursuant  to this  Section  2 until the
                           earlier  of (A)  three  (3) days  after the date upon
                           which such material  information  is disclosed to the
                           public or ceases to be  material or (B) 90 days after
                           the  Company  makes  such good  faith  determination;
                           provided, however, that the Company shall not utilize
                           this right more than once in any twelve month period;
                           or

                                    (iv)  except  as set forth in  Section  2.5,
                           after the second such  registration  pursuant to this
                           Section 2.1 has been declared or ordered effective.

         Subject to the foregoing clauses (i), (ii), (iii) and (iv), 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 Initiating Holders.

                  2.2  ADDITIONAL  SHARES  TO  BE  INCLUDED.   The  registration
statement filed pursuant to the request of the Initiating  Holders may,  subject
to the provisions of Sections 2.4 and 3.3 below, include (a) other securities of
the  Company  (the  "Additional  Shares")  which  are  held by (i)  officers  or
directors of the Company  who, by virtue of  agreements  with the  Company,  are
entitled to include  their  securities  in any such  registration  or (ii) other
persons who, by virtue of  agreements  with the Company,  including the Existing
Rights  Agreements,  are  entitled  to  include  their  securities  in any  such
registration (the "Other Stockholders"), and (b) securities of the Company being
sold for the account of the Company.

                  2.3 UNDERWRITING.

                           (a) If the  Initiating  Holders  intend to distribute
                  the Registrable  Securities  covered by their request by means
                  of an underwriting, they shall so advise the Company as a part
                  of their  request  made  pursuant  to this  Section  2 and the
                  Company shall include such  information  in the written notice
                  to other Holders  referred to in Section 2.1 above.  The right
                  of any Holder to registration pursuant to this Section 2 shall
                  be  conditioned  upon  such  Holder's  participation  in  such
                  underwriting  and the inclusion of such  Holder's  Registrable
                  Securities in the  underwriting  to the extent provided herein
                  and subject to the limitations  provided  herein. A Holder may
                  elect to  include  in such  underwriting  all or a part of the
                  Registrable Securities he holds.

                           (b) The Company  shall  (together  with all  Holders,
                  officers,   directors  and  Other  Stockholders  proposing  to
                  distribute   their  securities   through  such   underwriting)
                  negotiate  and  enter  into  an   underwriting   agreement  in
                  customary form with the  representative  of the underwriter or
                  underwriters  selected for such  underwriting by a majority in
                  interest of the Initiating Holders, which underwriter(s) shall
                  be reasonably acceptable to the Company.

                                       4


                  2.4 LIMITATIONS ON SHARES TO BE INCLUDED.  Notwithstanding any
other  provision of this Section 2, if the  representative  of the  underwriters
advises the  Initiating  Holders in writing  that  marketing  factors  require a
limitation on the number of shares to be  underwritten,  the number of shares of
securities that are entitled to be included in the registration and underwriting
shall be allocated in the following order of priority: first, among the Holders,
in  proportion,  as  nearly  as  practicable,   to  the  respective  amounts  of
Registrable  Securities  which  they  had  requested  to  be  included  in  such
registration;  second,  among the Other Stockholders that offer securities being
sold pursuant to the Existing  Rights  Agreements,  in proportion,  as nearly as
practicable,  to the  respective  amounts of  Additional  Shares  which they had
requested to be included in such  registration  pursuant to the Existing  Rights
Agreements or such other  proportion  among the Other  Stockholders as otherwise
provided in the Existing Rights Agreements; third, to the Company for securities
being sold for its own account; and thereafter, the number of shares that may be
included in the registration statement and underwriting shall be allocated among
all  officers or  directors or  remaining  Other  Stockholders,  in each case in
proportion,  as nearly as practicable,  to the respective  amounts of Additional
Shares which they had requested to be included in such  registration at the time
of filing the  registration  statement.  If the Company or any Holder,  officer,
director or Other  Stockholder who has requested  inclusion in such registration
as provided above disapproves of the terms of any such underwriting, such Person
may elect to withdraw such Person's Registrable  Securities or Additional Shares
therefrom  by  written  notice  to the  Company  and  the  underwriter  and  the
Initiating Holders.  Any Registrable  Securities or other securities excluded or
withdrawn from such underwriting shall also be withdrawn from such registration.
No Registrable  Securities or Additional  Shares excluded from such registration
by reason of such underwriters'  marketing  limitation shall be included in such
registration.  To facilitate  the  allocation of shares in accordance  with this
Section 2.4, the Company or  underwriter  or  underwriters  selected as provided
above may round the number of Registrable  Securities of any Holder which may be
included  in  such  registration  to the  nearest  100  shares.  Notwithstanding
anything  contained in this  Agreement to the  contrary,  the Holders shall have
priority over all other Persons with respect to the inclusion of any  securities
in any registration requested pursuant to this Section 2.

                  2.5  ADDITIONAL  DEMAND  REGISTRATION.  If with respect to the
last  registration  permitted  to be  exercised  by the  Holders of  Registrable
Securities  under  Section  2.1, the Holders are unable to register all of their
Registrable  Securities  because of the  operation  of Section 2.4 hereof,  such
Holders  shall be  entitled  to require  the  Company  to effect one  additional
registration  to  afford  the  Holders  an  opportunity  to  register  all  such
Registrable  Securities.  Such additional registration shall again be subject to
the provisions of this Section 2, including this Section 2.5.

         3. COMPANY REGISTRATION.

                  3.1 At any time after  March 1,  2006,  if the  Company  shall
determine to register under the  Securities Act any of its equity  securities or
securities  convertible into equity securities either for its own account or the
account  of a  security  holder or holders  exercising  any demand  registration
rights, other than a registration  relating solely to employee benefit plans, or
a  registration  relating  solely to a  Commission  Rule 145  transaction,  or a
registration on Form S-4 or S-8, or the Registration Statement of the Company on
Form SB-2 filed on or about June 29, 2004, (or any successor forms thereto), the
Company will:

                                       5


                           (a)  promptly  give to  each  Holder  written  notice
                  thereof  (which shall include a list of the  jurisdictions  in
                  which  the  Company   intends  to  attempt  to  qualify   such
                  securities  under  the  applicable  blue  sky or  other  state
                  securities laws); and

                           (b)  include in such  registration  (and,  subject to
                  Section 2.1(b)(i),  any related  qualification  under blue sky
                  laws or other  compliance),  and in any underwriting  involved
                  therein, all the Registrable Securities specified in a written
                  request or request, made by any Holder within thirty (30) days
                  after receipt of the written notice from the Company described
                  in clause (a) above, except as set forth in Section 3.3 below.
                  Such  written  request may specify all or a part of a Holder's
                  Registrable Securities.

                  3.2  UNDERWRITING.  If the  registration  of which the Company
gives  notice  pursuant  to  Section  3.1 is for a  registered  public  offering
involving an underwriting,  the Company shall so advise the Holders as a part of
the written notice given pursuant to Section 3.1(a).  The right of any Holder to
registration  pursuant to this Section 3 shall be conditioned upon such Holder's
participation   in  such   underwriting  and  the  inclusion  of  such  Holder's
Registrable  Securities in the underwriting to the extent provided  herein.  All
Holders proposing to distribute their securities through such underwriting shall
(together  with the Company and any  officers,  directors or Other  Stockholders
distributing  their  securities   through  such  underwriting)   enter  into  an
underwriting  agreement  in  customary  form  with  the  representative  of  the
underwriter  or  underwriters  selected  by the  Company.  A Holder may elect to
include in such  underwriting  all or a part of the  Registrable  Securities  he
holds.

                  3.3 LIMITATIONS ON SHARES TO BE INCLUDED.  Notwithstanding any
other provision of this Section 3, if the  representative of the underwriters of
an  offering  described  in Section  3.2  advises  the  Company in writing  that
marketing factors require a limitation or elimination on the number of shares to
be underwritten,  the representative may (subject to the allocation priority set
forth below) limit the number of or eliminate the  Registrable  Securities to be
included in the registration  and  underwriting  pursuant to this Section 3. The
Company shall so advise all holders of  securities  requesting  registration  in
such  offering,  and the number of shares of securities  that are entitled to be
included  in such  registration  and  underwriting  shall  be  allocated  in the
following  order of priority:  first, if such  underwritten  offering shall have
been initiated by the Company for the sale of securities for its own account, to
the Company for  securities  being sold for its own account;  second,  among the
Other  Stockholders  that offer  securities  being sold pursuant to the Existing
Rights Agreements,  in proportion,  as nearly as practicable,  to the respective
amounts of such  Additional  Shares  which they had  requested to be included in
such  registration  pursuant to the  Existing  Rights  Agreements  or such other
proportion  among the Other  Stockholders as otherwise  provided in the Existing
Rights  Agreements;  third,  among  the  Holders  in  proportion,  as  nearly as
practicable,  to the respective amounts of Registrable Securities which they had
requested to be included in such registration;  and fourth, if such registration
shall not have been  initiated  by the  Company,  to the Company for  securities
being sold for its own account; and thereafter, the number of shares that may be
included in the registration statement and underwriting shall be allocated among
all  officers or  directors or  remaining  Other  Stockholders,  in each case in
proportion,  as nearly as practicable,  to the respective  amounts of Additional
Shares which they had requested to be included in such

                                       6


registration at the time of filing the registration  statement. If any Holder of
Registrable Securities or any officer, director or Other Stockholder disapproves
of the terms of any such  underwriting,  he may elect to withdraw  therefrom  by
written notice to the Company and the underwriter. Any Registrable Securities or
other  securities  excluded or withdrawn  from such  underwriting  shall also be
withdrawn from such registration.  The Company shall have the right to terminate
or withdraw any  registration  initiated by it under this Section 3 prior to the
effectiveness  of such  registration  whether or not any  Holder has  elected to
include securities in such registration.

         4. EXPENSES OF  REGISTRATION.  All  Registration  Expenses  incurred in
connection  with any  registration,  qualification  or  compliance  pursuant  to

                                       9


                  5.2 It shall be a condition  precedent to the  obligations  of
the  Company to take any action  pursuant  to this  Agreement  that the  Holders
proposing to register  Registrable  Securities shall furnish to the Company such
information regarding themselves,  the Registrable  Securities held by them, and
their intended  method of  distribution  of such  Registrable  Securities as the
Company shall reasonably request and as shall be required in connection with the
action to be taken by the Company.

                  5.3 In  connection  with the  preparation  and  filing of each

Securities Act.

         6. INDEMNIFICATION.

                  6.1 INDEMNIFICATION BY THE COMPANY. The Company will indemnify
each Holder,  each of its  officers,  directors  and  partners,  and each person
controlling such Holder,  with respect to which  registration,  qualification or
compliance has been effected  pursuant to this Agreement,  and each underwriter,
if any,  and each  Person who  controls  any  underwriter,  against  all claims,
losses,  damages and  liabilities  (or actions,  proceedings  or  settlements in
respect  thereof)  arising out of or based on any untrue  statement  (or alleged
untrue  statement)  of a material  fact  contained in any  prospectus,  offering
circular  or other  document  (including  any  related  registration  statement,
notification or the like) incident to any such  registration,  qualification  or
compliance,  or based on any 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 any violation by the Company of the Securities Act or
any rule or  regulation  thereunder  applicable  to the Company and  relating to
action  or  inaction  required  of the  Company  in  connection  with  any  such
registration,  qualification or compliance, and will reimburse each such Holder,
each of its officers,  directors and partners,  and each Person controlling such
Holder, each such underwriter and each Person who controls any such underwriter,
for any legal and any other  expenses  reasonably  incurred in  connection  with
investigating and defending or settling any such claim, loss, damage,  liability
or action,  provided that the Company will not be liable in any such case to the
extent that any such claim, loss, damage,  liability or expense arises out of or
is based on any untrue  statement  or omission  made in reliance  upon and based
upon written information  furnished to the Company by such Holder or underwriter
and stated to be specifically for use therein.

                  6.2  INDEMNIFICATION  BY THE  HOLDERS.  Each Holder  will,  if
Registrable  Securities  held by him are included in the  securities as to which
such registration,  qualification or compliance is being effected, indemnify the
Company, each of its directors and officers and each underwriter, if any, of the
Company's securities covered by such a registration  statement,  each person who
controls  the Company  (other than such Holder) or such  underwriter  within the

                                       10


meaning of the Securities  Act and the rules and  regulations  thereunder,  each
other such Holder and each of their officers,  directors and partners,  and each
Person controlling such Holder or other stockholder, against all claims, losses,
damages, expenses and liabilities (or actions in respect thereof) arising out of
or based on any untrue  statement  (or alleged  untrue  statement) of a material
fact contained in any such registration statement, prospectus, offering circular
or other  document,  or any  omission (or alleged  omission) to state  therein a
material fact required to be stated  therein or necessary to make the statements
therein not  misleading,  and will reimburse the Company,  each of its directors
and officers,  each underwriter or control Person, each other Holder and each of
their officers,  directors and partners and each Person  controlling such Holder
or other stockholder for any legal or any other expenses  reasonably incurred in
connection  with  investigating  or  defending  any such  claim,  loss,  damage,
liability or action,  in each case to the extent,  but only to the extent,  that
such untrue  statement  (or alleged  untrue  statement)  or omission (or alleged
omission) is made in such registration statement,  prospectus, offering circular
or other  document in reliance upon and in conformity  with written  information
furnished  to the Company by such Holder and stated to be  specifically  for use
therein.

                  6.3 NOTICES OF CLAIMS, PROCEDURES, ETC. Each party entitled to
indemnification under this Section 6 (the "Indemnified Party") shall give notice
to the party  required to provide  indemnification  (the  "Indemnifying  Party")
promptly after such  Indemnified  Party has actual  knowledge of any claim as to
which indemnity may be sought, and shall permit the Indemnifying Party to assume
the defense of any such claim or any litigation  resulting  therefrom,  provided
that counsel for the  Indemnifying  Party, who shall conduct the defense of such
claim  or  any  litigation  resulting  therefrom,   shall  be  approved  by  the
Indemnified Party (whose approval shall not be unreasonably  withheld),  and the
Indemnified  Party may  participate in such defense at the  Indemnified  Party's
sole expense,  and provided further that the failure of any Indemnified Party to
give notice as provided herein shall not relieve the  Indemnifying  Party of its
obligations  under this  Section 7 unless  such  failure is  prejudicial  to the
ability of  Indemnifying  Party to defend such claim or action.  Notwithstanding
the  foregoing,  such  Indemnified  Party shall have the right to employ its own
counsel in any such litigation, proceeding or other action if (i) the employment
of such counsel has been authorized by the  Indemnifying  Party, in its sole and
absolute discretion, or (ii) the named parties in any such claims (including any
impleaded  parties) include any such Indemnified Party and the Indemnified Party
and the  Indemnifying  Party  shall have been  advised in writing  (in  suitable
detail) by counsel to the Indemnified  Party either (A) that there may be one or
more legal defenses available to such Indemnified Party which are different from
or additional to those available to the Indemnifying Party, or (B) that there is
a conflict of interest by virtue of the Indemnified  Party and the  Indemnifying
Parties  having  common  counsel,  in any of which  events,  the legal  fees and
expenses of a single  counsel for all  Indemnified  Parties with respect to each
such  claim,  defense  thereof,  or  counterclaims  thereto  shall  be  borne by
Indemnifying  Party. No Indemnifying  Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement  which does not include as an
unconditional  term  thereof  the giving by the  claimant or  plaintiff  to such
Indemnified  Party of a release  from all  liability in respect to such claim or
litigation.  Each  Indemnified  Party shall  cooperate to the extent  reasonably
required and furnish such information  regarding itself or the claim in question
as an  Indemnifying  Party may  reasonably  request in  writing  and as shall be
reasonably  required in  connection  with  defense of such claim and  litigation
resulting therefrom.

                                       11


         7. INFORMATION BY HOLDER.  Each Holder of Registrable  Securities shall
furnish  to  the  Company  such  information   regarding  such  Holder  and  the
distribution  proposed by such Holder as the Company may  reasonably  request in
writing and as shall be reasonably required in connection with any registration,
qualification or compliance referred to in this Agreement.

         8. TRANSFER OR ASSIGNMENT OF REGISTRATION  RIGHTS.  The rights to cause
the Company to register  securities  granted by the Company under this Agreement
may be  transferred  or assigned by a Holder to a transferee  or assignee of any
Registrable Securities;  provided that the Company is given written notice at or
prior to the time of said transfer or  assignment,  stating the name and address
of said  transferee or assignee and  identifying  the securities with respect to
which such registration  rights are being transferred or assigned;  and provided
further that the  transferee  or assignee of such rights  assumes in writing the
obligations of a Holder under this Agreement to the Company and other Holders in
effect at the time of transfer under all effective agreements.

         9. EXCHANGE ACT  COMPLIANCE.  So long as the Company remains subject to
the  reporting  requirements  of the Exchange  Act,  the Company  shall file the
reports required to be filed by it under the Securities Act and the Exchange Act
and the rules and  regulations  adopted by the Commission  thereunder,  and will
take  all  actions  reasonably   necessary  to  enable  holders  of  Registrable
Securities to sell such securities without registration under the Securities Act
within the  limitation of the  provisions  of (a) Rule 144 under the  Securities
Act,  as such Rule may be  amended  from time to time,  (b) Rule 144A  under the
Securities  Act, as such Rule may be amended from time to time, if applicable or
(c) any similar rules or regulations  hereunder adopted by the Commission.  Upon
the request of any Holder of Registrable Securities, the Company will deliver to
such  Holder a  written  statement  as to  whether  it has  complied  with  such
requirements.

         10. NO CONFLICT OF RIGHTS.  The Company will not  hereafter  enter into
any agreement  with respect to its  securities  which is  inconsistent  with the
rights granted to the Holders in this Agreement. Without limiting the generality
of the foregoing,  the Company will not hereafter  enter into any agreement with
respect to its securities  which grants or modifies any existing  agreement with
respect to its securities to grant to the holder of its securities in connection
with an incidental  registration of such securities  equal or higher priority to
the rights granted to the Holders under Sections 2 and 3 of this Agreement.

         11. BENEFITS OF AGREEMENT; SUCCESSORS AND ASSIGNS. This Agreement shall
be binding  upon and inure to the benefit of the  parties  and their  respective
successors  and  permitted  assigns,   legal  representatives  and  heirs.  This
