                    its Common Stock,  other than (i) pursuant to a Registration

                    Warrant Shares,  which shall offer such holders the right to
                    request  inclusion  of  any  Registrable  Securities  in the
                    proposed Registration.

               (b)  Each  holder of Shares or Warrant  Shares  shall have thirty
                    (30) days or such longer period as shall be set forth in the
                    notice  from the  receipt  of such  notice to deliver to the
                    Company a written request specifying the number of shares of
                    Registrable  Securities  such holder intends to sell and the

               (c)  The  Company  shall have the  exclusive  right to select all

                    securities of the Company,  including all Shares and Warrant
                    Shares.  In the event that the proposed  Registration by the
                    Company  is,  in whole or in part,  an  underwritten  public
                    offering of  securities  of the Company,  any request  under
                    Section 2.3(b) shall contain the holder's agreement that the
                    Registrable  Securities will be included in the underwriting
                    on the same  terms and  conditions  as the  shares of Common
                    Stock,  if any,  otherwise  being sold through  underwriters
                    under such Registration.

               (d)  Upon  receipt  of a  written  request  pursuant  to  Section
                    2.3(b),  the Company shall  promptly use its best efforts to
                    cause all such Registrable  Securities to be Registered,  to
                    the extent  required  to permit sale or  disposition  as set
                    forth in the written request.


               (e)  Notwithstanding the foregoing,  if the managing  underwriter
                    of an underwritten public offering determines and advises in
                    writing  that the  inclusion of all  Registrable  Securities
                    proposed to be included in the underwritten public offering,
                    together with any shares  proposed to be sold by the Company
                    for its own  account  and any other  issued and  outstanding
                    shares of Common  Stock  proposed to be included  therein by
                    holders  other than the  holders of  Registrable  Securities
                    (such  other  holders'   shares   hereinafter   collectively
                    referred to as the "Other Shares"), would interfere with the
                    successful  marketing  of  the  securities  proposed  to  be
                    included in the underwritten public offering,  including the
                    price at which such  securities can be sold, then the number
                    of such  shares  of  persons  other  than the  Company  that
                    otherwise  would be  included  in such  underwritten  public
                    offering  shall be excluded  from such  underwritten  public
                    offering  in a  number  deemed  necessary  by such  managing
                    underwriter,  first by excluding,  to the extent  necessary,
                    Other  Shares  held  by  persons  who  have  not   exercised
                    contractual  rights to include  such Shares in the  offering
                    pursuant to the Prior  Registration  Rights  Agreements  (as
                    hereinafter defined), and then, to the extent necessary,  by
                    excluding  Registrable  Securities   participating  in  such
                    underwritten public offering,  pro rata, based on the number
                    of shares of Registrable  Securities each holder proposes to
                    include; and, then, excluding to the extent necessary, Other
                    Shares  proposed  to be  included  by the  holders  of Other
                    Shares who have  exercised  registration  rights  granted to
                    them under registration  rights agreements of the Company in
                    effect on the date hereof or any other  registration  rights
                    in  effect  on the date  hereof  (collectively,  the  "Prior
                    Registration Rights Agreements").

               (f)  The registration rights provided by this Agreement shall not
                    be in force with respect to any Registrable  Security if (i)
                    a  Registration  Statement  that  includes  the  Registrable
                    Security  is  effective;  (ii) the  Registrable  Security is
                    eligible  for resale  under Rule 144  without  regard to the
                    volume  limitations  thereof;  and (iii) five years form the
                    date hereof have elapsed.

          2.4  Preparation  and Filing.  If and whenever the Company is under an
               obligation  pursuant to the  provisions  of this Section 2 to use
               its best efforts to effect,  the  Registration of any Registrable
               Securities, the Company shall, as expeditiously as practicable:

               (a)  prepare  and  file  with  the   Commission  a   Registration
                    Statement with respect to such Registrable Securities, using
                    such  form  of  available   Registration   Statement  as  is
                    reasonably   selected  by  the  Company  (unless   otherwise
                    specified  herein),  and use its best  efforts to cause such
                    Registration  Statement  to  become  and  remain  effective,


                    keeping   each  Selling   Shareholder   advised  as  to  the
                    initiation, progress and completion of the Registration;

               (b)  prepare and file with the  Commission  such  amendments  and
                    supplements   to  such   Registration   Statements  and  the
                    prospectus used in connection  therewith as may be necessary
                    to keep such  Registration  Statement  effective for, in the
                    case of a  Required  Registration  under  Section  2.2,  the
                    period set forth in  Section  2.2(b)  and,  in the case of a
                    Piggyback Registration under Section 2.3, six months, and to
                    comply  with  the  provisions  of the  Securities  Act  with
                    respect to the sale or other  disposition of all Registrable
                    Securities covered by such Registration Statement;

               (c)  furnish to each Selling Shareholder such number of copies of
                    any  summary  prospectus  or other  prospectus,  including a
                    preliminary prospectus,  in conformity with the requirements
                    of the  Securities  Act,  and such other  documents  as such
                    Selling  Shareholder  may  reasonably  request  in  order to
                    facilitate  the  public  sale or other  disposition  of such
                    Registrable  Securities;  provided,  however,  that  no such
                    prospectus  need be  furnished  more than,  in the case of a
                    Required  Registration  under  Section 2.2, six months after
                    the  conclusion  of the period  set forth in Section  2.2(b)
                    and, in the case of a Piggyback  Registration  under Section
                    2.3, six months after the effective date of the Registration
                    Statement related thereto;

               (d)  use its best efforts to register or qualify the  Registrable
                    Securities covered by such Registration  Statement under the
                    securities  or blue sky laws of such  jurisdictions  as each
                    Selling  Shareholder shall reasonably request and do any and
                    all other acts or things which may be  reasonably  necessary
                    or advisable to enable such holder to consummate  the public
                    sale or  other  disposition  in such  jurisdictions  of such
                    Registrable Securities;  provided, however, that the Company
                    shall not be  required  to  consent  to  general  service of
                    process,  qualify to do  business  as a foreign  corporation
                    where it would  not be  otherwise  required  to  qualify  or
                    submit to liability for state or local taxes where it is not
                    liable for such taxes; and

               (e)  at any time when a prospectus  covered by such  Registration
                    Statement is required to be delivered  under the  Securities
                    Act  within  the  appropriate  period  mentioned  in Section
                    2.2(b) or Section 2.3(b) hereof,  as the case may be, notify
                    each Selling  Shareholder 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  and,  at the  request of such
                    seller,   prepare,   file  and  furnish  to  such  seller  a
                    reasonable  number  of  copies  of a  supplement  to  or  an
                    amendment of


                    such  prospectus  as may be necessary so that, as thereafter
                    delivered to the purchasers of such shares,  such prospectus
                    shall not include an untrue  statement of a material fact or
                    omit to state a material fact required to be stated  therein
                    or necessary to make the statement therein not misleading in
                    the light of the  circumstances  then existing.  The Company
                    may delay  amending or  supplementing  the  prospectus for a
                    period not to exceed 45 days if the Company is then  engaged
                    in negotiations  regarding a material  transaction  that has
                    not  otherwise  been  publicly  disclosed,  and the  Selling
                    Shareholders  shall  suspend  their sale of Shares  until an
                    appropriate  supplement or prospectus  has been forwarded to
                    them or the proposed transaction is abandoned.

                    Notwithstanding the foregoing,  with respect to the proposed
                    Registration of Registrable  Securities  pursuant to Section
                    2.3 hereof,  the Company  may  withdraw or cease  proceeding
                    with any proposed Registration of Registrable  Securities if
                    it has  withdrawn  or ceased  proceeding  with the  proposed
                    Registration  of Common  Stock of the Company with which the
                    Registration  of  such  Registrable  Securities  was  to  be
                    included.

          2.5  Expenses.   The  Company  shall  pay  all  Registration  Expenses
               incurred by the Company in complying with this Section 2.

          2.6  Information  Furnished  by  Purchaser.  It shall  be a  condition
               precedent to the Company's obligations under this Agreement as to
               any Selling  Shareholder that each Selling Shareholder furnish to
               the Company in writing such  information  regarding  such Selling
               Shareholder  and  the  distribution   proposed  by  such  Selling
               Shareholder as the Company may reasonably request.

          2.7  Indemnification.

               2.7.1    Company's  Indemnification  of  Purchasers.  The Company
                        shall  indemnify each Selling  Shareholder,  each of its
                        officers,  directors and constituent partners,  and each
                        person controlling (within the meaning of the Securities
                        Act)  such  Selling  Shareholder,  against  all  claims,
                        losses,  damages or  liabilities  (or actions in respect
                        thereof)  suffered or  incurred  by any of them,  to the
                        extent such claims, losses, damages or liabilities arise
                        out  of or are  based  upon  any  untrue  statement  (or
                        alleged  untrue  statement) of a material fact contained
                        in any prospectus or any related Registration  Statement
                        incident to any such  Registration,  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,  or any violation by
                        the Company of any rule or regulation  promulgated under
                        the   Securities  Act  applicable  to  the  Company  and
                        relating to actions or inaction  required of the Company
                        in  connection  with  any  such  Registration;  and  the
                        Company will  reimburse  each such Selling  Shareholder,
                        each of its officers, directors and constituent partners
                        and  each   person  who   controls   any  such   Selling
                        Shareholder,  for any


                        reasonable, documented legal and other expenses incurred
                        in connection with  investigating  or defending any such
                        claim,  loss,  damage,  liability  or action;  provided,
                        however,  that the  indemnity  contained in this Section
                        2.7.1 shall not apply to amounts paid in  settlement  of
                        any such claim,  loss,  damage,  liability  or action if
                        settlement  is  effected  without  the  consent  of  the
                        Company  (which  consent  shall  not   unreasonably   be
                        withheld); and provided,  further, 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 upon any untrue (or  alleged  untrue)
                        statement  or omission  based upon  written  information
                        furnished  to the Company by such  Selling  Shareholder,
                        underwriter,  controlling  person  or other  indemnified
                        person and stated to be for use in  connection  with the
                        offering of securities of the Company.

                  2.7.2 Selling  Shareholder's  Indemnification of Company. Each
                        Selling Shareholder shall indemnify the Company, each of
                        its directors and officers, each underwriter, if any, of
                        the  Company's  securities  covered  by  a  Registration
                        Statement,  each person who controls the Company or such
                        underwriter  within the meaning of the  Securities  Act,
                        and  each  other  Selling   Shareholder,   each  of  its
                        officers,  directors and  constituent  partners and each
                        person  controlling  such  other  Selling   Shareholder,
                        against all claims,  losses, damages and liabilities (or
                        actions in respect thereof)  suffered or incurred by any
                        of them  and  arising  out of or based  upon any  untrue
                        statement  (or alleged  untrue  statement) of a material
                        fact contained in such Registration Statement or related
                        prospectus,  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, or any violation by such Selling Shareholder
                        of  any  rule  or  regulation   promulgated   under  the
                        Securities  Act  applicable to such Selling  Shareholder
                        and  relating  to actions or  inaction  required of such
                        Selling  Shareholder in connection with the Registration
                        of  the   Registrable   Securities   pursuant   to  such
                        Registration Statement;  and will reimburse the Company,
                        such  other  Selling   Shareholders,   such   directors,
                        officers,    partners,    persons,    underwriters   and
                        controlling persons for any reasonable, documented legal
                        and  other   expenses   incurred  in   connection   with
                        investigating or defending any such claim, loss, damage,
                        liability  or  action;  provided,   however,  that  such
                        indemnification   and  reimbursement  shall  be  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
                        or prospectus  in reliance  upon and in conformity  with
                        written  information  furnished  to the  Company by such
                        Selling   Shareholder  and  stated  to  be  for  use  in
                        connection with the offering of Registrable Securities.



                  2.7.3 Indemnification Procedure.  Promptly after receipt by an
                        indemnified  party  under this  Section 2.7 of notice of
                        the  commencement of any action which may give rise to a
                        claim for  indemnification  hereunder,  such indemnified
                        party will, if a claim in respect  thereof is to be made
                        against an  indemnifying  party under this  Section 2.7,
                        notify  the   indemnifying   party  in  writing  of  the
                        commencement   thereof  and  generally   summarize  such
                        action.  The indemnifying  party shall have the right to
                        participate  in and to assume the defense of such claim,
                        and shall be entitled to select  counsel for the defense
                        of such claim with the approval of any parties  entitled
                        to   indemnification,   which   approval  shall  not  be
                        unreasonably  withheld.  Notwithstanding  the foregoing,
                        the parties entitled to  indemnification  shall have the
                        right   to   employ   separate    counsel    (reasonably
                        satisfactory to the  indemnifying  party) to participate
                        in the  defense  thereof,  but the fees and  expenses of
                        such  separate  counsel  shall be at the expense of such
                        indemnified  parties  unless  the named  parties to such
                        action  or  proceedings  include  both the  indemnifying
                        party and the indemnified  parties and the  indemnifying
                        party  or  such  indemnified  parties  shall  have  been
                        advised  by  counsel  that  there are one or more  legal
                        defenses available to the indemnified  parties which are
                        different  from or additional to those  available to the
                        indemnifying  party (in which case,  if the  indemnified
                        parties  notify the  indemnifying  party in writing that
                        they elect to employ separate  counsel at the reasonable
                        expense  of the  indemnifying  party,  the  indemnifying
                        party  shall not have the right to assume the defense of
                        such action or proceeding  on behalf of the  indemnified
                        parties,   it  being  understood,   however,   that  the
                        indemnifying  party  shall not, in  connection  with any
                        such action or proceeding  or separate or  substantially
                        similar  or  related  action or  proceeding  in the same
                        jurisdiction arising out of the same general allegations
                        or   circumstances,   be  liable  for  the   reasonable,
                        documented  fees and  expenses of more than one separate
                        counsel at any time for all indemnified  parties,  which
                        counsel shall be designated in writing by the Purchasers
                        of a majority of the Registrable Securities).

                  2.7.4 Contribution.  If the  indemnification  provided  for in
                        this   Section  2.7  from  an   indemnifying   party  is
                        unavailable to an indemnified party hereunder in respect
                        to any losses, claims, damages,  liabilities or expenses
                        referred to herein, then the 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, claims, damages, liabilities
                        or  expenses in such  proportion  as is  appropriate  to
                        reflect the relative fault of the indemnifying party and
                        indemnified  party in connection  with the statements or
                        omissions which result in such losses, claims,  damages,
                        liabilities  or expenses,  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
                        the untrue or  alleged  untrue  statement  of a material
                        fact or the  omission  or


                        alleged  omission  to state a material  fact  relates to
                        information  supplied  by  such  indemnifying  party  or
                        indemnified  party  and the  parties'  relative  intent,
                        knowledge,   access  to  information  supplied  by  such
                        indemnifying  party or indemnified party and opportunity
                        to correct or prevent such  statement  or omission.  The
                        amount  paid or  payable  by a party as a result  of the
                        losses,  claims,   damages,   liabilities  and  expenses
                        referred  to  above  shall  be  deemed  to  include  any
                        documented  legal or other fees or  expenses  reasonably
                        incurred by such party in connection with  investigating
                        or defending any action,  suit,  proceeding or claim, or
                        in collecting such indemnity or  reimbursement  from the
                        indemnifying party.

3. Covenants of the Company.

          The Company agrees to:

          (a)  Notify  the  holders  of  Registrable  Securities  included  in a
               Registration  Statement of (i) the issuance by the  Commission of
               any stop order suspending the  effectiveness of such Registration
               Statement  and  (ii)  upon  learning  of  the  initiation  of any
               proceedings for the purpose of suspending such effectiveness, the
               existence  of such  proceedings.  The  Company  will  make  every
               reasonable  effort to prevent the issuance of any stop order and,
               if any stop order is issued, to obtain the lifting thereof at the
               earliest possible time.

          (b)  If the  Common  Stock is then  listed  on a  national  securities
               exchange,   use  its  best  efforts  to  cause  the   Registrable
               Securities to be listed on such exchange.  If the Common Stock is
               not then listed on a national securities  exchange,  use its best
               efforts to facilitate the reporting of the Registrable Securities
               on NASDAQ.

          (c)  Take all other  reasonable  actions  necessary  to  expedite  and
               facilitate  disposition  of  the  Registrable  Securities  by the
               holders thereof pursuant to the Registration Statement.

          (d)  With a view to making  available  to the  holders of  Registrable
               Securities  the  benefits  of  Rule  144  promulgated  under  the
               Securities Act and any other rule or regulation of the Commission
               that may at any time permit the Purchasers to sell  securities of
               the  Company  to the public  without  registration,  the  Company
               agrees to:

               (i)  make and  keep  adequate  current  public  information  with
                    respect  to  the  Company  available,  as  those  terms  are
                    understood  and  defined in Rule 144,  at all times after 90
                    days  after the  effective  date of the  first  Registration
                    Statement  filed  by the  Company  for the  offering  of its
                    securities to the general public;

               (ii) file with the  Commission in a timely manner all reports and
                    other documents required of the Company under the Securities
                    Act and the  Securities  Exchange  Act of  1934  (the  "1934
                    Act"); and



               (iii)furnish to each holder of Shares,  so long as such holder of
                    Shares owns any Shares, forthwith upon written request (a) a
                    written  statement  by  the  Company  as to  whether  it has
                    complied  with the reporting  requirements  of Rule 144, the
                    Securities  Act and the  1934  Act,  (b) a copy of the  most
                    recent  annual or  quarterly  report of the Company and such
                    other  reports and documents so filed by the Company and (c)
                    such other information as may be reasonably requested and as
                    is publicly  available  in availing the holders of Shares of
                    any rule or regulation of the  Commission  which permits the
                    selling of any such securities without registration.

          (e)  Prior to the filing of a Registration  Statement or any amendment
               thereto (whether  pre-effective or post-effective),  and prior to
               the filing of any  prospectus  or prospectus  supplement  related
               thereto,  the Company will provide each Selling  Shareholder with
               copies of all pages thereto, if any, which reference such Selling
               Shareholder.

4.  Miscellaneous.

          (a)  This Agreement  shall be governed by and construed under the laws
               of the  State of  Connecticut  without  regard  to any  otherwise

          (b)  The terms and  conditions  of this  Agreement  shall inure to the
               benefit  of and be binding  upon the  respective  successors  and
               assigns of the Purchaser (including  transferees of any shares of
               the Series C Stock or any Common Stock of the Corporation  issued
               upon  conversion  thereof).  Notwithstanding  the  foregoing,  no
               registration  rights  shall be  exercisable  with  respect to any
               share after such share has been sold  pursuant to a  Registration
               Statement declared effective under the Securities Act. Nothing in
               this  Agreement,  express or implied,  is intended to confer upon
               any party  other  than the  parties  hereto  or their  respective
               successors  and  assigns any rights,  remedies,  obligations,  or
               liabilities  under or by  reason  of this  Agreement,  except  as
               expressly provided in this Agreement.

          (c)  This Agreement and the other documents  delivered pursuant hereto
               constitute the full and entire  understanding and agreement among
               the parties with regard to the subjects hereof and no party shall
               be  liable  or bound to any  other  party  in any  manner  by any
               representations,  warranties,  covenants or agreements  except as
               specifically  set  forth  herein  or  therein.  Nothing  in  this
               Agreement,  express or  implied,  is  intended to confer upon any
               party,  other  than  the  parties  hereto  and  their  respective
               successors   and  permitted   assigns,   any  rights,   remedies,
               obligations, or liabilities under or by reason of this Agreement,
               except as expressly provided herein.

          (d)  In the  event  that  any  provision  of this  Agreement  shall be
               invalid,  illegal  or  unenforceable,  it  shall,  to the  extent
               practicable,  be  modified  so as to make  it  valid,  legal  and
               enforceable  and to retain as nearly as practicable the intent of
               the parties, and the validity legality, and enforceability of the


               remaining provisions shall not in any way be affected or impaired
               thereby.  To the extent  permitted by law, the parties  waive the
               benefit of any provision of law that renders any provision of the
               Agreement invalid or unenforceable in any respect.

          (e)  Except as otherwise  provided herein,  any term of this Agreement
               may be amended,  and the observance of any term of this Agreement
               may be waived  (either  generally  or in a  particular  instance,
               either retroactively or prospectively, and either for a specified
               period of time or indefinitely),  with the written consent of the
               Company and the Purchaser.

          (f)  All  notices  and  other  communications  required  or  permitted
               hereunder  shall be in  writing  and shall be deemed  effectively
               given upon personal delivery, on the first business day following
               mailing  by  overnight  courier,  or on the fifth  day  following
               mailing  by  registered  or  certified   mail,   return   receipt
               requested,  postage  prepaid,  addressed  to the  Company  at its
               address  as  set  forth  in  the  Purchase  Agreement  and to the
               Purchaser at its address as shown on the books of the Company.

          (g)  The titles of the paragraphs and  subparagraphs of this Agreement
               are  for  convenience  of  reference  only  and  are  not  to  be
               considered in construing this Agreement.

          (h)  This  Agreement  may be executed  in any number of  counterparts,
               each of  which  shall be  deemed  an  original,  but all of which
               together shall constitute one instrument.

          (i)  No  waiver  by any  party  to this  Agreement  of any one or more
               defaults by any other party or parties in the  performance of any
               of the  provisions  hereof  shall  operate or be  construed  as a
               waiver of any future  default or  defaults,  whether of a like or
               different nature. Except as expressly provided herein, no failure
               or delay on the part of any party in exercising any right,  power
               or remedy hereunder shall operate as a waiver thereof,  nor shall
               any single or partial exercise of any such right, power or remedy
               preclude any other or further exercise thereof or the exercise of
               any other right, power or remedy.
