JOSEPHTHAL LYON & ROSS INCORPORATED,  (hereinafter  referred to variously as the

                                   WITNESSETH

         WHEREAS,  the Company proposes to issue to the Placement Agent warrants
("Warrants")  to purchase up to an aggregate of 150,000  shares of common stock,
$.01 par value, of the Company (the "Common Stock"); and

         WHEREAS, the Placement Agent has agreed pursuant to the placement agent
agreement (the "Placement Agent  Agreement")  dated as of the date hereof by and
between the  Placement  Agent and the Company to act as the  Placement  Agent in
connection with the Company's proposed offering of its shares of Common Stock in
an aggregate  offering of not less than $3,400,000 nor more than $5,000,000 (the
"Offering"); and

         WHEREAS,  the Warrants to be issued  pursuant to this Agreement will be
issued on the  Closing  Date (as such term is  defined  in the  Placement  Agent
Agreement) by the Company to the Placement  Agent in  consideration  for, and as
part of the Placement  Agent's  compensation  in connection  with, the Placement
Agent acting as the Placement Agent pursuant to the Placement Agent Agreement;

         NOW,  THEREFORE,  in  consideration of the mutual premises made herein,
the payment by the Placement Agent to the Company of an aggregate of ten dollars
($10.00),   the  agreements  herein  set  forth  and  other  good  and  valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

         1. GRANT.  The Holder is hereby  granted the right to purchase,  at any
time from  March 31,  1997  until  5:30  P.M.,  New York  time,  on the 90th day
following the date on which the Company's  registration statement filed with the
Securities and Exchange  Commission  ("SEC") which includes the shares of Common
Stock  issuable  upon exercise of the Warrants  (the  "Warrant  Securities")  is
declared  effective by the SEC (the  "Expiration  Date"),  up to an aggregate of
150,000  shares  of  Common  Stock at an  initial  exercise  price  (subject  to
adjustment  as provided in Section 8 hereof) of $9.60 per share of Common  Stock
subject to the terms and conditions of this Agreement.

         2.  WARRANT  CERTIFICATES.   The  warrant  certificates  (the  "Warrant
Certificates") delivered and to be delivered pursuant to this Agreement shall be
in the form set forth in Exhibit A attached hereto and made a part hereof,  with
such appropriate insertions,  omissions,  substitutions, and other variations as
required or permitted by this Agreement.

         3. EXERCISE OF WARRANT.  The Warrants  initially are  exercisable at an
exercise price (subject to adjustment as provided in Section 8 hereof) per share
of Common Stock set forth


in Section 6 hereof  payable by  certified  or  official  bank check in New York
Clearing House funds.  Upon surrender of a Warrant  Certificate with the annexed
Form of  Election  to  Purchase  duly  executed,  together  with  payment of the
Exercise Price (as hereinafter defined) for the shares of Common Stock purchased
at the Company's  principal offices presently located at 6714 Netherlands Drive,
Wilmington,  North Carolina 28405 the registered holder of a Warrant Certificate
("Holder"  or  "Holders")   shall  be  entitled  to  receive  a  certificate  or
certificates  for the shares of Common Stock so purchased.  The purchase  rights
represented  by each Warrant  Certificate  are  exercisable at the option of the
Holder  thereof,  in whole or in part  (but not as to  fractional  shares of the
Common Stock underlying the Warrants).  In the case of the purchase of less than
all the shares of Common Stock  purchasable under any Warrant  Certificate,  the
Company shall cancel said Warrant  Certificate  upon the  surrender  thereof and
shall  execute  and  deliver a new  Warrant  Certificate  of like  tenor for the
balance of the shares of Common Stock purchasable thereunder.

         4. ISSUANCE OF  CERTIFICATES.  Upon the exercise of the  Warrants,  the
issuance  of  certificates  for  shares  of  Common  Stock or other  securities,
properties or rights  underlying such Warrants,  shall be made forthwith (and in
any event within  three (3)  business  days  thereafter)  without  charge to the
Holder thereof including,  without  limitation,  any tax which may be payable in
respect of the issuance  thereof,  and such  certificates  shall (subject to the
provisions  of  Sections  5 and 7  hereof)  be issued in the name of, or in such
names as may be directed by, the Holder  thereof;  provided,  however,  that the
Company  shall not be required to pay any tax which may be payable in respect of
any transfer involved in the issuance and delivery of any such certificates in a
name  other than that of the Holder and the  Company  shall not be  required  to
issue or  deliver  such  certificates  unless  or until the  person  or  persons
requesting  the  issuance  thereof  shall have paid to the Company the amount of
such tax or shall have  established to the satisfaction of the Company that such
tax has been paid.

         The Warrant  Certificates and the certificates  representing the Common
Stock (and/or other securities, property or rights issuable upon the exercise of
the  Warrants)  shall be  executed  on behalf of the  Company  by the  manual or
facsimile  signature of the then present  Chairman or Vice Chairman of the Board
of Directors or President or Vice  President of the Company  under its corporate
seal reproduced thereon, attested to by the manual or facsimile signature of the
then  present  Secretary  or  Assistant   Secretary  of  the  Company.   Warrant
Certificates  shall be dated the date of  execution  by the Company upon initial
issuance, division, exchange, substitution or transfer.

         5.  RESTRICTION  ON  TRANSFER  OF  WARRANTS.  The  Holder  of a Warrant
Certificate,  by its acceptance thereof,  covenants and agrees that the Warrants
are being  acquired  as an  investment  and not with a view to the  distribution
thereof;  and  that  the  Warrants  may  not  be  sold,  transferred,  assigned,
hypothecated or otherwise  disposed of, in whole or in part, for a period of one
(1) year from the date hereof, except to officers of the Representative.

                                        2



         6. EXERCISE PRICE.

         6.1 INITIAL AND ADJUSTED EXERCISE PRICE.  Except as otherwise  provided
in Section 8 hereof,  the initial  exercise price of each Warrant shall be $9.60
per share of Common Stock. The adjusted  exercise price shall be the price which
shall  result  from time to time  from any and all  adjustments  of the  initial
exercise price in accordance with the provisions of Section 8 hereof.

         6.2 EXERCISE  PRICE.  The term  "Exercise  Price" herein shall mean the
initial  exercise  price or the  adjusted  exercise  price,  depending  upon the
context.

         7.  REGISTRATION RIGHTS.

         The Warrant Securities shall be included in the registration  statement
to be prepared  and filed by the Company  with the SEC  pursuant to the terms of
that certain  Registration  Rights  Agreement of even date herewith by and among
the  Company,  the  investors  in the  Offering  and the  Placement  Agent.  The
Registration  Rights  Agreement is  incorporated  herein by reference and made a
part hereof,  and it is expressly agreed that the Warrant  Securities shall have
all of the rights and  privileges  of the shares of Common  Stock  which are the
subject of the Registration  Rights Agreement,  and that the Holders of Warrants
are third party beneficiaries of the Registration Rights Agreement.

         8.  ADJUSTMENTS TO EXERCISE PRICE AND NUMBER OF SECURITIES.

         8.1 SUBDIVISION AND COMBINATION.  In case the Company shall at any time
subdivide or combine the outstanding  shares of Common Stock, the Exercise Price
shall  forthwith  be  proportionately  decreased in the case of  subdivision  or
increased in the case of combination.

         8.2 STOCK DIVIDENDS AND DISTRIBUTIONS.  In case the Company shall pay a
dividend  in,  or make a  distribution  of,  shares  of  Common  Stock or of the
Company's  capital stock convertible into Common Stock, the Exercise Price shall
forthwith be  proportionately  decreased.  An  adjustment  made pursuant to this
Section 8.2 shall be made as of the record date for the subject  stock  dividend
or distribution.

         8.3  ADJUSTMENT IN NUMBER OF  SECURITIES.  Upon each  adjustment of the
Exercise  Price  pursuant  to the  provisions  of this  Section 8, the number of
Securities  issuable  upon the exercise at the adjusted  exercise  price of each
Warrant  shall be adjusted to the nearest  full amount by  multiplying  a number
equal to the Exercise Price in effect  immediately  prior to such  adjustment by
the number of Warrant Shares issuable upon exercise of the Warrants  immediately
prior to such  adjustment  and  dividing the product so obtained by the adjusted
Exercise Price.

                                        3

         8.4 DEFINITION OF COMMON STOCK. For the purpose of this Agreement,  the
term "Common Stock" shall mean (i) the class of stock designated as Common Stock
in the Certificate of  Incorporation  of the Company as may be amended as of the
date hereof, or (ii) any other class of stock resulting from successive  changes
or  reclassifications  of such Common Stock consisting  solely of changes in par
value, or from par value to no par value, or from no par value to par value.

         8.5  MERGER  OR  CONSOLIDATION.  In  case of any  consolidation  of the
Company  with,  or merger of the Company  with,  or merger of the Company  into,
another  corporation (other than a consolidation or merger which does not result
in  any  reclassification  or  change  of the  outstanding  Common  Stock),  the
corporation  formed by such consolidation or merger shall execute and deliver to
the Holder a supplemental  warrant  agreement  providing that the holder of each
Warrant then  outstanding or to be outstanding  shall have the right  thereafter
(until the  expiration  of such  Warrant)  to  receive,  upon  exercise  of such
warrant,  the kind and  amount  of shares  of stock  and  other  securities  and
property receivable upon such consolidation or merger, by a holder of the number
of shares of Common Stock of the Company for which such warrant  might have been
exercised  immediately prior to such  consolidation,  merger,  sale or transfer.
Such supplemental warrant agreement shall provide for adjustments which shall be
identical to the adjustments  provided in Section 8. The above provision of this
subsection shall similarly apply to successive consolidations or mergers.

         8.6 NO ADJUSTMENT OF EXERCISE PRICE IN CERTAIN CASES.  No adjustment of
the Exercise Price shall be made:

             (a) Upon the  issuance  or sale of the  Warrants  or the  shares of
Common Stock issuable upon the exercise of the Warrants; or

             (b) If the amount of said  adjustment  shall be less than two cents
(2(cent)) per Warrant Share, provided, however, that in such case any adjustment
that would  otherwise be required  then to be made shall be carried  forward and
shall be made at the time of and together  with the next  subsequent  adjustment
which, together with any adjustment so carried forward, shall amount to at least
two cents (2(cent)) per Warrant Share.

         9.  EXCHANGE  AND  REPLACEMENT  OF WARRANT  CERTIFICATES.  Each Warrant
Certificate is exchangeable  without expense,  upon the surrender thereof by the
registered  Holder at the principal  executive office of the Company,  for a new
Warrant  Certificate  of like tenor and date  representing  in the aggregate the
right to purchase  the same number of Warrant  Shares in such  denominations  as
shall be designated by the Holder thereof at the time of such surrender.

         Upon receipt by the Company of evidence  reasonably  satisfactory to it
of the loss, theft,  destruction or mutilation of any Warrant Certificate,  and,
in case of loss,  theft or  destruction,  of  indemnity  or security  reasonably
satisfactory to it, and reimbursement to the Company of all reasonable  expenses
incidental thereto, and upon surrender and cancellation

                                        4



of the Warrants,  if mutilated,  the Company will make and deliver a new Warrant
Certificate of like tenor, in lieu thereof.

         10.  ELIMINATION  OF  FRACTIONAL  INTERESTS.  The Company  shall not be
required to issue certificates  representing fractions of shares of Common Stock
upon the  exercise of the  Warrants,  nor shall it be required to issue scrip or
pay cash in lieu of  fractional  interests,  it being the intent of the  parties
that all fractional interests shall be eliminated by rounding any fraction up to
the  nearest  whole  number  of  shares  of  Common  Stock or other  securities,
properties or rights.

         11.  RESERVATION  AND LISTING OF  SECURITIES.  The Company shall at all
times reserve and keep available out of its  authorized  shares of Common Stock,
solely for the  purpose of issuance  upon the  exercise  of the  Warrants,  such
number of shares of Common Stock or other  securities,  properties  or rights as
shall be issuable upon the exercise  thereof.  The Company  covenants and agrees
that,  upon exercise of the Warrants and payment of the Exercise Price therefor,
all shares of Common  Stock and other  securities  issuable  upon such  exercise
shall be duly and validly issued, fully paid,  non-assessable and not subject to
the  preemptive  rights of any  stockholder.  As long as the  Warrants  shall be
outstanding,  the  Company  shall use its best  efforts  to cause all  shares of
Common Stock issuable upon the exercise of the Warrants to be listed (subject to
official  notice of  issuance) on all  securities  exchanges on which the Common
Stock  issued to the public in  connection  herewith  may then be listed  and/or
quoted on The Nasdaq Stock Market, Inc.

         12.  NOTICES TO WARRANT  HOLDERS.  Nothing  contained in this Agreement
shall be  construed  as  conferring  upon the  Holders  the  right to vote or to
consent or to receive  notice as a  stockholder  in respect of any  meetings  of
stockholders for the election of directors or any other matter, or as having any
rights  whatsoever as a stockholder  of the Company.  If,  however,  at any time
prior to the expiration of the Warrants and their exercise, any of the following
events shall occur:

              (a) the  Company  shall take a record of the holders of its shares
of Common  Stock for the  purpose of  entitling  them to  receive a dividend  or
distribution  payable otherwise than in cash, or a cash dividend or distribution
payable otherwise than out of current or retained earnings,  as indicated by the
accounting  treatment  of such  dividend  or  distribution  on the  books of the
Company; or

              (b) the Company shall offer to all the holders of its Common Stock
any additional shares of capital stock of the Company or securities  convertible
into or exchangeable for shares of capital stock of the Company,  or any option,
right or warrant to subscribe therefor; or

              (c) a dissolution, liquidation or winding up of the Company (other
than  in  connection  with  a  consolidation  or  merger)  or a  sale  of all or
substantially  all of its property,  assets and business as an entirety shall be
proposed; then, in any one or more of said events,

                                        5



the Company  shall give written  notice of such event at least fifteen (15) days
prior to the date  fixed as a record  date or the date of closing  the  transfer
books for the  determination  of the  stockholders  entitled  to such  dividend,
distribution,  convertible or exchangeable securities or subscription rights, or
entitled to vote on such proposed dissolution,  liquidation, winding up or sale.
Such notice  shall  specify such record date or the date of closing the transfer
books,  as the case may be.  Failure to give such  notice or any defect  therein
shall not  affect  the  validity  of any  action  taken in  connection  with the
declaration or payment of any such dividend,  or the issuance of any convertible
or exchangeable securities,  or subscription rights, options or warrants, or any
proposed dissolution, liquidation, winding up or sale.

         13. NOTICES. All notices,  requests,  consents and other communications
hereunder  shall be in  writing  and  shall be deemed to have been duly made and
sent when delivered,  or mailed by registered or certified mail,  return receipt
requested:

              (a) If to the registered Holder of the Warrants, to the address of
such Holder as shown on the books of the Company; or

              (b) If to the  Company,  to the  address  set  forth in  Section 3
hereof or to such other  address as the Company may  designate  by notice to the

any other provisions in regard to matters or questions  arising  hereunder which
the Company and the  Placement  Agent may deem  necessary or desirable and which
the  Company  and the  Placement  Agent  deem  shall not  adversely  affect  the
interests of the Holders of Warrant Certificates.

business  on the  earlier  to  occur of (i) the day the  last  Warrant  Security
issuable hereunder is issued, and (ii) the Expiration Date.

         17. GOVERNING LAW: Submission to Jurisdiction.  This Agreement and each
Warrant Certificate issued hereunder shall be deemed to be a contract made under
the laws of the State of New York and for all  purposes  shall be  construed  in
accordance  with the laws of said  State  without  giving  effect  to its  rules
governing the conflicts of laws.

enforced  in the  courts  of the  State of New York or of the  United  States of
America for the Southern  District of New York, and  irrevocably  submit to such
jurisdiction,  which  jurisdiction  shall  be  exclusive.  The  Company  and the
Placement  Agent  hereby  irrevocably  waive  any  objection  to such  exclusive
jurisdiction  or  inconvenient  forum.  Any such process or summons to be served
upon the  Company or the  Placement  Agent (at the option of the party  bringing
such action,  proceeding or claim) may be served by transmitting a copy thereof,
by registered or certified  mail,  return receipt  requested,  postage  prepaid,

Agent agree that the  prevailing  party(ies)  in any such  action or  proceeding
shall  be  entitled  to  recover  from the  other  party(ies)  all of  its/their

affect any other provision of this Agreement.

         20.  CAPTIONS.  The caption  headings of the Sections of this Agreement

This Warrant Certificate  certifies that --------, or registered assigns, is the
registered  holder of 150,000  Warrants,  each Warrant  entitling  the holder to
purchase  initially,  at any time from March 31,  1997 until 5:30 p.m.  New York
time on the 90th day  following  the date on which  the  Company's  registration
statement  filed with the  Securities  and  Exchange  Commission  ("SEC")  which

upon the exercise hereof is declared  effective by the SEC ("Expiration  Date"),
one fully-paid and non-assessable  share of Common Stock of C-Phone Corporation,
a New York corporation (the "Company"),  at the initial exercise price,  subject
to adjustment in certain  events (the "Exercise  Price"),  of $9.60 per share of
Common  Stock upon  surrender  of this  Warrant  Certificate  and payment of the
Exercise  Price at an  office  or  agency of the  Company,  but  subject  to the
conditions set forth herein and in the warrant  agreement  dated as of March 31,
1997 by and between the Company and  Josephthal  Lyon & Ross  Incorporated  (the
"Warrant  Agreement").  Payment of the Exercise Price shall be made by certified
or official bank check in New York Clearing  House funds payable to the order of
the Company or by surrender of this Warrant Certificate.

                                        9



         No Warrant  may be  exercised  after 5:30 p.m.,  New York time,  on the
Expiration Date, at which time all Warrants  evidenced hereby,  unless exercised
prior thereto, hereby shall thereafter be void.

         The Warrants  evidenced by this Warrant  Certificate are part of a duly
authorized  issue of Warrants  issued pursuant to the Warrant  Agreement,  which
Warrant Agreement is hereby incorporated by reference in and made a part of this
instrument and is hereby referred to for a description of the rights, limitation
of rights, obligations,  duties and immunities thereunder of the Company and the
holders  (the words  "holders"  or "holder"  meaning the  registered  holders or
registered holder) of the Warrants.

         The Warrant  Agreement  provides  that upon the  occurrence  of certain
events the Exercise Price and the type and/or number of the Company's securities
issuable  thereupon may,  subject to certain  conditions,  be adjusted.  In such
event,  the Company  will,  at the  request of the  holder,  issue a new Warrant
Certificate  evidencing  the  adjustment  in the  Exercise  Price and the number
and/or type of securities issuable upon the exercise of the Warrants;  provided,
however,  that the failure of the Company to issue such new Warrant Certificates
shall not in any way  change,  alter,  or  otherwise  impair,  the rights of the
holder as set forth in the Warrant Agreement.

         Upon due  presentment  for  registration  of transfer  of this  Warrant
Certificate at an office or agency of the Company, a new Warrant  Certificate or
Warrant Certificates of like tenor and evidencing in the aggregate a like number
of Warrants  shall be issued to the  transferee(s)  in exchange for this Warrant
Certificate,  subject to the  limitations  provided  herein  and in the  Warrant
Agreement,  without any charge except for any tax or other  governmental  charge
imposed in connection with such transfer.

         Upon the  exercise of less than all of the  Warrants  evidenced by this
Certificate,  the  Company  shall  forthwith  issue to the  holder  hereof a new
Warrant Certificate representing such number of unexercised Warrants.

         The Company may deem and treat the registered  holder(s)  hereof as the
absolute owner(s) of this Warrant Certificate  (notwithstanding  any notation of
ownership  or other  writing  hereon  made by  anyone),  for the  purpose of any
exercise hereof,  and of any distribution to the holder(s)  hereof,  and for all
