                          REGISTRATION RIGHTS AGREEMENT


         THIS REGISTRATION RIGHTS AGREEMENT,  dated the 31st day of March, 1997,
between the person listed on the signature  page hereto (the  "Subscriber")  and
C-PHONE  CORPORATION,  a New York  corporation  having  its  principal  place of
business at 6714 Netherlands Drive, Wilmington, NC 28405 (the "Company").

         WHEREAS,  the  Company  is  a  party  to  certain  Securities  Purchase
Agreements dated the date hereof (the "Purchase Agreements"),  pursuant to which
it has agreed to issue and sell an aggregate of not less than three million four
hundred  thousand  dollars  ($3,400,000)  nor more  than  five  million  dollars
($5,000,000)  of its shares (the  "Shares") of common stock,  $.01 par value per
share ("Common Stock"), and accompanying  contingent value rights (the "Rights",
and collectively with the Shares the "Securities"); and

         WHEREAS,  the  Company  has agreed to grant to the  Subscriber  and the
other subscriber  parties to the various Purchase  Agreements  (each, a "Holder"
and collectively,  the "Holders") certain  registration  rights set forth herein
with respect to the Securities; and

         WHEREAS,  Daniel Flohr,  President and Chief  Executive  Officer of the
Company ("Flohr") has delivered to Josephthal Lyon & Ross  Incorporated  ("JLR")
250,000 shares of his Common Stock (the "Escrowed Shares") to be used to satisfy
certain obligations to the Holders.

         NOW, THEREFORE, the parties hereto mutually agree as follows:

         Section  1.   REGISTRABLE   SECURITIES.   As  used  herein,   the  term
"Registrable  Security" means the Shares and the shares of Common Stock issuable
upon exercise of the Rights (the "Right Shares");  provided,  however, that with
respect to any particular Registrable Security,  such security shall cease to be
a Registrable  Security when, as of the date of  determination,  (i) it has been
effectively  registered  under the Securities Act of 1933, as amended (the "1933
Act") and disposed of pursuant thereto,  (ii) registration under the 1933 Act is
no longer required for the immediate public distribution of such Common Stock as
a result of the  provisions  of Rule 144,  or (iii)  with  respect  to any Right
Shares,  they  have  not yet  been  issued  and the  Rights  have  ceased  to be
outstanding.  The term  "Registrable  Securities"  means any  and/or  all of the
shares of Common Stock falling within the foregoing  definition of a Registrable
Security.   In  the  event  of  any   merger,   reorganization,   consolidation,
recapitalization  or other change in corporate  structure  affecting  the Common
Stock,  such adjustment shall be made in the definition of Registrable  Security
as is  appropriate in order to prevent any dilution or enlargement of the rights
granted pursuant to this Section 1.

         Section  2.  RESTRICTIONS  ON  TRANSFER.  The Holder  acknowledges  and
understands  that prior to the  registration  of the  Registrable  Securities as
provided herein,  the Securities are "restricted  securities" as defined in Rule
144 promulgated  under the 1933 Act. The Holder  understands that no disposition
or transfer of the Securities may be made by the Holder in the absence of (i) an
opinion of counsel reasonably satisfactory to the Company that such transfer may
be made,  or (ii) a  registration  statement  under  the  1933  Act  then  being
effective with respect thereto.

         Section 3.   REGISTRATION RIGHTS.

         (a) At any time commencing fifteen (15) days after the date hereof, the
Holders owning at least thirty-three  percent (33%) of the Shares shall have the
right (if not previously exercised by any other Holder or Holders),  exercisable
by written notice to the Company (the "Demand  Registration  Request"),  to have
the Company  prepare and file with the Securities and Exchange  Commission  (the
"SEC") within five


(5) days  after  receipt  of the  Demand  Registration  Request  a  registration
statement on Form S-3 (the "Registration  Statement"),  on one occasion,  at the
sole  expense of the Company  (except as provided in Section  3(c)  hereof),  in
respect of all Holders of  Registrable  Securities,  each of whom shall have the
right to include their Registrable  Securities  therein if they have provided to
the Company,  within five (5) days after receipt thereof,  a properly  completed
questionnaire  of the type  commonly  used for  offerings of this kind, so as to
permit a public offering and sale of the Registrable  Securities  under the 1933
Act.

         (b) The Company  will use its  reasonable  best efforts to maintain any
Registration  Statement or  post-effective  amendment filed under this Section 3
hereof  current under the 1933 Act until the earlier of (i) the date that all of
the Registrable Securities have been sold pursuant to the Registration Statement
and  (ii)  the  first  anniversary  of the  effective  date of the  Registration
Statement.

         (c) All  fees,  disbursements  and  out-of-pocket  expenses  and  costs
incurred by the Company in  connection  with the  preparation  and filing of any
Registration   Statement  under  Section  3(a)  hereof  and  in  complying  with
applicable  securities and Blue Sky laws  (including,  without  limitation,  all
attorneys'  fees) shall be borne by the Company.  The Holder shall bear the cost
of underwriting discounts and commissions, if any, applicable to the Registrable
Securities  being  registered  and the fees and  expenses  of its  counsel.  The
Company at its expense  will supply the Holder with copies of such  Registration
Statement and the  prospectus or offering  circular  included  therein and other
related  documents  in such  quantities  as  reasonably  may be requested by the
Holder.

         (d) The Company  shall not be  required by this  Section 3 to include a
Holder's  Registrable  Securities in any  Registration  Statement which is to be
filed if, in the  opinion of counsel  for both the Holder and the  Company  (or,
should  they not  agree,  in the  opinion  of  another  counsel  experienced  in
securities law matters  reasonably  acceptable to counsel for the Holder and the
Company) the proposed  offering or other transfer as to which such  registration
is requested is exempt from  applicable  federal and state  securities  laws and
would result in all purchasers or transferees thereof obtaining securities which
are not "restricted securities", as defined in Rule 144 under the 1933 Act.

         (e) (i) In the event that the Registration Statement to be filed by the
Company  pursuant to Section  3(a) hereof is not  declared  effective by the SEC
within  ninety  five  (95) days  after  receipt  by the  Company  of the  Demand
Registration  Request,  then JLR shall cause to be  delivered  from the Escrowed
Shares to each Holder,  as a penalty,  for each day thereafter until the earlier
of (A) the date that the  Registration  Statement  is  declared  effective  (the
"Effective  Date") and (B) the 185th day after the receipt by the Company of the
Demand Registration Request, all rights with respect to such number of shares of
Common  Stock as shall equal the  product of (x) 1,000 and (y) a  fraction,  the
numerator of which is the purchase  price paid for the  Securities by the Holder
and the  denominator  of  which is the  aggregate  purchase  price  paid for the
Securities by all of the Holders.

              (ii) In the event that the Registration  Statement is not declared
effective by the SEC within one hundred  eighty five (185) days after receipt by
the  Company  of the Demand  Registration  Request,  then JLR shall  cause to be
delivered from the Escrowed Shares to each Holder, as a penalty, all rights with
respect to such  number of shares of Common  Stock as shall equal the product of
(A) 160,000 and (B) a fraction,  the  numerator of which is the  purchase  price
paid  for the  Securities  by the  Holder  and the  denominator  of which is the
aggregate purchase price paid for the Securities by all of the Holders.

         (f) No  provision  contained  herein  shall  preclude  the Company from
selling  securities  pursuant  to any  Registration  Statement  in  which  it is
required to include Registrable Securities pursuant to this Section 3.

         Section 4. APPROVAL OF ISSUANCE OF EXCESS RIGHTS.  Notwithstanding  the
obligation  of the Company  hereunder to register the Right  Shares,  the Holder
acknowledges that,  pursuant to the listing  requirements of The Nasdaq National
Market ("NNM"), the Company will be required to seek the approval (the "Rights

                                        2


Proposal") of its shareholders  prior to the issuance of any Excess Right Shares
(as defined below). For purposes of this Agreement,  "Excess Right Shares" shall
mean any  Right  Shares  in excess of the  difference  between  870,000  and the
aggregate number of Shares sold pursuant to the Purchase Agreements. The Company
agrees  (i) to  include  the  Rights  Proposal  in its proxy  materials  for the
Company's  regularly scheduled 1997 Annual Meeting of Shareholders to be held no
later  than  August 30,  1997,  (ii) to use its best  efforts  to obtain  timely
clearance  from  the SEC of such  proxy  materials,  (iii)  to mail  such  proxy
materials  in a timely  manner  and (iv) to use its best  efforts  to cause  the
Company's  board of  directors  to  recommend  (and not  subsequently  withdraw)
approval of the Rights Proposal to shareholders.

         Section 5.  COOPERATION  WITH THE COMPANY.  The Holders will reasonably
cooperate  with the Company in all respects in connection  with this  Agreement,
including,  timely supplying all information reasonably requested by the Company
and executing and  returning  all documents  reasonably  requested in connection
with the registration and sale of the Registrable Securities.

         Section 6.  REGISTRATION  PROCEDURES.  If and  whenever  the Company is
required by any of the provisions of this  Agreement to effect the  registration
of any of the  Registrable  Securities  under the 1933 Act,  the  Company  shall
(except as otherwise provided in this Agreement), expeditiously:

         (a)  prepare  and file  with the SEC and the  National  Association  of
Securities Dealers, Inc., if applicable,  such amendments and supplements to the
Registration Statement and the prospectus used in connection therewith as may be
necessary to keep the  Registration  Statement  effective and to comply with the
provisions of the 1933 Act with respect to the sale or other  disposition of all
Registrable Securities covered by the Registration Statement whenever the Holder
or Holders of such  Registrable  Securities  shall  desire to sell or  otherwise
dispose of the same (including prospectus  supplements with respect to the sales
of securities  from time to time in  connection  with a  Registration  Statement
pursuant to Rule 415 under the 1933 Act);

         (b)  furnish  to each  Holder  such  numbers  of  copies  of a  summary
prospectus  or other  prospectus,  including  a  preliminary  prospectus  or any
amendment or supplement to any prospectus,  in conformity with the  requirements
of the 1933 Act, and such other documents, as such Holder may reasonably request
in order to facilitate the public sale or other  disposition of the  Registrable
Securities owned by such Holder;

         (c) use its  reasonable  best  efforts  to  register  and  qualify  the
Registrable  Securities  covered by the Registration  Statement under such other
securities  or  blue  sky  laws  of  such  jurisdictions  as the  Holders  shall
reasonably  request,  and do any and all  other  acts and  things  which  may be
necessary or advisable  to enable each Holder to  consummate  the public sale or
other disposition in such jurisdictions of such Registrable  Securities owned by
such Holder,  except that the Company shall not for any such purpose be required
to qualify to do business as a foreign  corporation in any jurisdiction  wherein
it is not so  qualified  or to file  therein any  general  consent to service of
process;

         (d) use its best efforts to list the Registrable  Securities on the NNM
or any  securities  exchange on which the Common  Stock is then  listed,  if the
listing of such Registrable  Securities is then permitted under the rules of the
NNM or such exchange;

         (e)  enter  into and  perform  its  obligations  under an  underwriting
agreement,  if the offering is an underwritten  offering, in usual and customary
form,  with  the  managing  underwriter  or  underwriters  of such  underwritten
offering;

         (f)  notify  each  Holder  of  Registrable  Securities  covered  by the
Registration  Statement,  at any time when a prospectus relating thereto covered
by the Registration Statement is required to be delivered under the 1933 Act, of
the  happening  of any event of which it has  knowledge as a result of which the
prospectus included in the Registration  Statement,  as then in effect, includes
an untrue statement of a

                                        3


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.

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

         Section 8.  ASSIGNMENT OF REGISTRATION  RIGHTS.  The rights granted the
Holders under this  Agreement may not be assigned  except to a transferee of all
or a portion of the Registrable Securities.

         Section 9.  TERMINATION  OF  REGISTRATION  RIGHTS.  The rights  granted
pursuant to this  Agreement  shall  terminate  as to each Holder (and  permitted
transferee under Section 8 hereof) upon the occurrence of any of the following:

         (a) all such Holder's Registrable  Securities subject to this Agreement
have been sold; or

         (b) such Holder's Registrable  Securities subject to this Agreement may
be sold without such  registration  pursuant to Rule 144  promulgated by the SEC
pursuant to the 1933 Act.

         Section 10.  INDEMNIFICATION.

         (a) In the  event of the  filing  of any  Registration  Statement  with
respect to  Registrable  Securities  pursuant  to Section 3 hereof,  the Company
agrees to indemnify  and hold  harmless the Holder and each person,  if any, who
controls the Holder within the meaning of the 1933 Act ("Distributing  Holders")
against any losses,  claims,  damages or  liabilities,  joint or several  (which
shall, for all purposes of this Agreement,  include,  but not be limited to, all
costs of defense and  investigation  and all attorneys'  fees and expenses),  to
which  the  Distributing  Holders  may  become  subject,  under  the 1933 Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect  thereof) arise out of or are based upon any untrue statement or alleged
untrue  statement  of any  material  fact  contained  in any  such  Registration
Statement,  or any related preliminary  prospectus,  final prospectus,  offering
circular,  notification or amendment or supplement  thereto,  or arise out of or
are based upon the omission or alleged omission to state therein a material fact
required to be stated  therein or necessary to make the  statements  therein not
misleading;  provided,  however, that the Company will not be liable in any such
case to the extent that any such loss, claim,  damage or liability arises out of
or is based upon an untrue  statement or alleged untrue statement or omission or
alleged omission made in such Registration  Statement,  preliminary  prospectus,
final  prospectus,  offering  circular,  notification or amendment or supplement
thereto in reliance upon, and in conformity with, written information  furnished
to  the  Company  by  the  Distributing  Holders,  specifically  for  use in the
preparation  thereof.  This  indemnity  agreement  will  be in  addition  to any
liability which the Company may otherwise have.

         (b) Each  Distributing  Holder  agrees that it will  indemnify and hold
harmless the Company,  and each officer,  director of the Company or person,  if
any, who controls  the Company  within the meaning of the 1933 Act,  against any
losses,  claims,  damages or liabilities  (which shall, for all purposes of this
Agreement,   include,   but  not  be  limited  to,  all  costs  of  defense  and
investigation  and all attorneys' fees and expenses) to which the Company or any
such officer,  director or controlling  person may become subject under the 1933
Act or otherwise,  insofar as such losses  claims,  damages or  liabilities  (or
actions in respect thereof); arise out of or are based upon any untrue statement
or alleged  untrue  statement of any material fact  contained in a  Registration
Statement,  or any related preliminary  prospectus,  final prospectus,  offering
circular,  notification or amendment or supplement  thereto,  or arise out of or
are based upon the omission or the alleged  omission to state therein a material
fact required to be stated therein or necessary to make the  statements  therein
not misleading,  but in each case only to the extent that such untrue  statement
or alleged

                                        4


untrue statement or omission or alleged  omission was made in such  Registration
Statement,   preliminary  prospectus,   final  prospectus,   offering  circular,
notification  or  amendment  or  supplement  thereto in  reliance  upon,  and in
conformity  with,  written   information   furnished  to  the  Company  by  such
Distributing  Holder,  specifically  for  use in the  preparation  thereof  and,
provided further,  that the indemnity  agreement contained in this Section 10(b)
shall not  inure to the  benefit  of the  Company  with  respect  to any  person
asserting such loss,  claim,  damage or liability who purchased the  Registrable
Securities  which are the subject thereof if the Company was responsible for the
failure  to send  or  give  (in  violation  of the  1933  Act or the  rules  and
regulations  promulgated  thereunder) a copy of the prospectus contained in such
Registration Statement to such person at or prior to the written confirmation to
such person of the sale of such  Registrable  Securities,  where the Company was
obligated to do so under the 1933 Act or the rules and  regulations  promulgated
thereunder.  This indemnity agreement will be in addition to any liability which
the Distributing Holders may otherwise have.

         (c) Promptly after receipt by an  indemnified  party under this Section
of notice of the commencement of any action,  such indemnified  party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section,  notify the  indemnifying  party of the commencement  thereof;  but the
omission so to notify the  indemnifying  party will not relieve the indemnifying
party from any liability  which it may have to any  indemnified  party otherwise
than as to the particular item as to which  indemnification is then being sought
solely pursuant to this Section.  In case any such action is brought against any
indemnified  party, and it notifies the  indemnifying  party of the commencement
thereof,  the indemnifying party will be entitled to participate in, and, to the
extent that it may wish,  jointly with any other  indemnifying  party  similarly
notified,  assume the defense thereof,  subject to the provisions  herein stated
and after notice from the indemnifying  party to such  indemnified  party of its
election so to assume the defense thereof,  the  indemnifying  party will not be
liable to such  indemnified  party  under  this  Section  for any legal or other
expenses  subsequently incurred by such indemnified party in connection with the
defense  thereof  other  than  reasonable  costs of  investigation,  unless  the
indemnifying party shall not pursue the action to its final conclusion, in which
event,  such legal or other  expenses  shall  become the  responsibility  of the
indemnifying  party from and after it relinquishes  its role of so pursuing such
action. The indemnified party shall have the right to employ separate counsel in
any such  action and to  participate  in the defense  thereof,  but the fees and
expenses of such counsel shall not be at the expense of the  indemnifying  party
if the  indemnifying  party has assumed  the defense of the action with  counsel
reasonably   satisfactory  to  the  indemnified  party;  provided  that  if  the
indemnified  party is the  Distributing  Holder,  the fees and  expenses of such
counsel shall be at the expense of the indemnifying  party if (i) the employment
of such counsel has been specifically  authorized in writing by the indemnifying
party,  or (ii) the named  parties to any such action  (including  any impleaded
parties) include both the Distributing Holder and the indemnifying party and the
Distributing  Holder  shall have been  advised by such counsel that there may be
one or more legal defenses available to the indemnifying party different from or
in conflict with any legal defenses  which may be available to the  Distributing
Holder (in which case the indemnifying  party shall not have the right to assume
the  defense  of such  action  on behalf of the  Distributing  Holder,  it being
understood,  however,  that the indemnifying party shall, in connection with any
one such action or separate but substantially  similar or related actions in the
same jurisdiction  arising out of the same general allegations or circumstances,
be liable only for the  reasonable  fees and  expenses of one  separate  firm of
attorneys  for all  Distributing  Holders,  which  firm shall be  designated  in
writing by the  Distributing  Holders).  No settlement of any action  against an
indemnified  party  shall be made  without  the  prior  written  consent  of the
indemnified party, which consent shall not be unreasonably withheld.

         Section 11.  CONTRIBUTION.  In order to provide for just and  equitable
contribution under the 1933 Act in any case in which (i) the Distributing Holder
makes  a  claim  for  indemnification  pursuant  to  Section  10  hereof  but is
judicially  determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding  the fact  that the  express  provisions  of  Section  10 hereof
provide for  indemnification  in such case, or (ii) contribution  under the 1933
Act may be required on the part of any Distributing Holder, then the Company and
the applicable  Distributing  Holder shall  contribute to the aggregate  losses,
claims, damages or liabilities to which they may be subject (which

                                        5



shall, for all purposes of this Agreement,  include,  but not be limited to, all
costs of defense and  investigation  and all attorneys'  fees and expenses),  in
either such case (after contribution from others) on the basis of relative fault
as well as any other relevant equitable considerations. The relative fault 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 the Company on the one hand
or the  applicable  Distributing  Holder,  on the other hand,  and the  parties'
relative intent, knowledge,  access to information and opportunity to correct or
prevent  such  statement or omission.  The Company and the  Distributing  Holder
agree that it would not be just and equitable if  contribution  pursuant to this
Section  were  determined  by pro rata  allocation  or by any  other  method  of
allocation which does not take account of the equitable  considerations referred
to in this  Section.  The amount  paid or payable by an  indemnified  party as a
result of the  losses,  claims,  damages or  liabilities  (or actions in respect
thereof)  referred to above in this Section shall be deemed to include any legal
or other expenses  reasonably  incurred by such indemnified  party in connection
with  investigating  or defending any such action or claim.  No person guilty of
fraudulent  misrepresentation  (within the meaning of Section  11(f) of the 1933
Act) shall be  entitled  to  contribution  from any person who was not guilty of
such  fraudulent  misrepresentation.  Notwithstanding  the  provisions  of  this
Section 11, the Holder shall not be required to contribute  any amount in excess
of the Purchase Price.

         Section  12.  NOTICES.  Any notice  pursuant to this  Agreement  by the
Company  or by the Holder  shall be in writing  and shall be deemed to have been
duly given if  delivered  by (i) hand,  (ii) by  facsimile  and followed by mail
delivery,  or (iii) if mailed  by  certified  mail,  return  receipt  requested,
postage prepaid, addressed as follows:

         Section 13.  ASSIGNMENT.  This  Agreement is binding upon and inures to
the benefit of the parties  hereto and their  respective  heirs,  successors and
permitted assigns. This Agreement cannot be assigned, amended or modified by the
parties hereto,  except by written agreement  executed by the parties hereto. If
requested  by the  Company,  the Holder  shall have  furnished to the Company an
opinion of counsel reasonably satisfactory to the Company to such effect.

         Section  14.   COUNTERPARTS.   This   Agreement   may  be  executed  in
counterparts,  each of  which  shall be  deemed  an  original,  but all of which
together shall constitute one and the same instrument.

York, with regard to conflicts of law principles.

         Section 17. SEVERABILITY.  If any provision of this Agreement shall for
any reason be held invalid or unenforceable,  such invalidity or unenforceablity
shall  not  affect  any  other  provision  hereof  and this  Agreement  shall be
