                               REGISTRATION RIGHTS

     2.1 Registration Rights.

        2.2.1 Subject to the terms  hereof,  if: (i) at any time or from time to
time the  Company  shall  determine  to  register  any of its  securities  in an
Underwritten  Public Offering  (except for  registration  statements on Form S-8
relating to employee benefit plans); and (ii) DDI or any Qualified Transferee is
the  beneficial  owner of any  Registrable  Securities;  then the  Company  will
promptly give to the Holders  written  notice thereof no less than ten (10) days
prior  to  the  filing  of any  registration  statement,  and  include  in  such
Underwritten Public Offering (and any related  qualification under blue sky laws
or other compliance),  such Registrable Securities as the Holders may request in
a writing  delivered  to the  Company  within  five (5) days after the  Holders'
receipt of the Company's written notice.

        2.2.2  Notwithstanding  any  other  provision  of this  Section,  if the
managing  underwriter  of such  Underwritten  Public  Offering  concludes in its
reasonable  judgment  that the  number of shares to be  registered  for  selling
shareholders  (including the Holders)  would  materially  adversely  affect such
offering,  subject  to the  terms of any  agreements  which  may  grant to other
persons senior  registration  rights to which the Company is a party, the number
of Registrable  Securities to be registered,  together with the number of shares
of Common Stock or other  securities held by other  shareholders  proposed to be
registered in such  offering,  shall be reduced on a pro rata basis based on the
number of Registrable  Securities proposed to be sold by the Holders as compared
to the number of shares proposed to be sold by all shareholders. The Registrable
Securities so excluded by the managing  underwriter shall be withdrawn from such
registration,  and shall not be  transferred in a public  distribution  prior to
ninety (90) days after the effective date of the registration statement relating
thereto,  or such other shorter period of time as the managing  underwriter  may
require.

        2.2.3 The Company  shall have the right to  terminate  or  withdraw  any
registration  initiated by it under this Section prior to the  effectiveness  of
such registration  whether or not the Holders have elected to include securities
in such registration.

     2.2 Expenses of Registration.  All Registration  Expenses shall be borne by
the Company.  Unless otherwise stated herein,  all Selling Expenses  relating to
securities registered on behalf of the Holders shall be borne by the Holders

     2.3   Registration   Procedures.   In  the   case  of  each   registration,
qualification   or  compliance   effected  by  the  Company   pursuant  to  this
Registration  Rights  Agreement,  the Company  will keep the Holders  advised in
writing as to the initiation of each registration,  qualification and compliance
and as to the completion thereof. At its expense, the Company will:

        2.3.1 Prepare and file with the Commission a registration statement with
respect to such securities and use its commercially  reasonable efforts to cause
such   registration   statement  to  become  and  remain   effective  until  the
distribution described in such registration statement has been completed;

        2.3.2  Furnish to the  Holders  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 the Holders may reasonably  request
in order to  facilitate  the  public  sale of the  shares  by the  Holders,  and
promptly  furnish to the  Holders  notice of any  stop-order  or similar  notice
issued by the  Commission  or any state agency  charged with the  regulation  of
securities.

     2.4 Certain Information. The Holders agree, with respect to any Registrable
Securities  included  in  any  registration,  to  furnish  to the  Company  such
information   regarding  the  Holders,   the  Registrable   Securities  and  the
distribution  proposed by the Holders as the Company may  reasonably  request in
writing  and  as  shall  be  required  in  connection  with  any   registration,
qualification or compliance referred to herein.

     2.5  Assignment.  Neither  this  Agreement,  nor  any  right,  interest  or
obligation hereunder, may be assigned by either of the parties without the prior
written consent of the other party;  provided,  however,  that any assignment by
DDI to any Qualified  Transferee  shall not require the prior written consent of
the other  party.  The Company  shall not be  obligated  to  recognize  any such
assignment by DDI to a Qualified  Transferee  unless and until the Company shall
have received  written  notice from DDI  specifying  the name and address of the
Qualified  Transferee(s) and identifying the Registrable Securities with respect
to which such rights hereunder have been assigned.
