                                                                    ------------


                     INVESTOR REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement"), dated as of
January 6, 2006, by and among Thomas Pharmaceuticals, Inc., a New Jersey
corporation, with its principal office located at 750 Route 34, Matawan, NJ,
07747 (the "Company"), and iVoice, Inc., a New Jersey corporation, with its
principal office at 750 Route 34, Matawan, NJ, 07747 (the "iVoice").

         WHEREAS:

         A. The Company was formed by the merger (the "Merger") of Thomas
Pharmaceuticals Ltd., a New York corporation ("TPL"), with and into Thomas
Pharmaceuticals, Ltd. (f/k/a iVoice Acquisition Corp.), a New Jersey corporation
("iVoice Acquisition"), pursuant to the terms of that certain Agreement and Plan
of Merger, by and among the iVoice, iVoice Acquisition, TPL and the then
Shareholders of TPL, dated as of the date hereof (the "Merger Agreement"), and
pursuant to the Merger Agreement and the Transaction Documents (as defined
therein), (i) the then Shareholders of TPL (the "Series A Preferred
Shareholders") acquired and now hold one hundred percent (100%) of the
outstanding shares of Series A Preferred Stock of the Company, no par value per
share (the "Series A Preferred Stock"), and (ii) iVoice acquired and will
acquire up to seven hundred and fifty (750) shares of the Series B Preferred
Stock of the Company, no par value per share (the "Series B Preferred Stock"),
and (B) one hundred (100) shares of the Common Stock of the Company, no par
value per share.

         B. (i) Immediately prior to the merger, iVoice Acquisition issued to
iVoice (A) three hundred twenty five (325) shares of the Company's Series B
Preferred Stock, no par value per share (the "Series B Preferred Stock"), (B) a
purchased convertible debenture in the principal amount of Three Hundred Sixty
Thousand Dollars ($360,000) and (C) an convertible debenture issued as payment
for the agreement to provide certain administrative services in the principal
amount of One Hundred Thousand Dollars ($100,000) (together, the "Initial
Convertible Debentures"), each of which were converted into securities of the
Company on the same terms and conditions they were issued by iVoice Acquisition
immediately prior to the merger, and (ii) pursuant to the terms of the Merger
Agreement, iVoice has agreed to purchase (A) additional convertible debentures
in an aggregate principal amount of up to Four Hundred Twenty Five Thousand
Dollars ($425,000) at par (together with the Initial Convertible Debentures, the
"Convertible Debentures"), an (B) four hundred twenty five additional shares of
Series B Preferred Stock (all such securities of the Company being referred to
herein as the "Convertible Securities"), each convertible into shares of the
Company's common stock, no par value per share (the "Common Stock"). Capitalized
terms not defined herein shall have the meaning ascribed to them in the
Convertible Debentures.

         C. To induce the iVoice to purchase or otherwise acquire the
Convertible Securities, iVoice Acquisition agreed, and the Company hereby
agrees, that the Company would provide certain registration rights under the
Securities Act of 1933, as amended, and the rules and

<PAGE>

regulations there under, or any similar successor statute (collectively, the
"Securities Act"), and applicable state securities laws.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants contained herein and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Company, iVoice
and each other Investor (as defined herein), if any, hereby agree as follows:

                  1. DEFINITIONS.

         As used in this Agreement, the following terms shall have the following
meanings:

         (a) "Investor" means iVoice and any transferee or assignee thereof to
whom iVoice or any other Investor assigns its rights under this Agreement and
who agrees to become bound by the provisions of this Agreement in accordance
with Section 9 hereof.

         (b) "Person" means a corporation, a limited liability company, an
association, a partnership, an organization, a business, an individual, a
governmental or political subdivision thereof or a governmental agency.

         (c) "Register," "registered," and "registration" refer to a
registration effected by preparing and filing one or more Registration
Statements (as defined below) in compliance with the Securities Act and pursuant
to Rule 415 under the Securities Act of 1933, as amended (the "Securities Act")
or any successor rule providing for offering securities on a continuous or
delayed basis ("Rule 415"), and the declaration or ordering of effectiveness of
such Registration Statement(s) by the United States Securities and Exchange SEC
(the "SEC").

         (d) "Registrable Securities" means the shares of Common Stock issuable
to Investors upon conversion of the Convertible Securities.

         (e) "Registration Statement" means a registration statement under the
Securities Act which covers the Registrable Securities.

                  2. REGISTRATION.

         (a) Subject to the terms and conditions of this Agreement, the Company
shall prepare and file, no later than thirty (30) days from the date (i) the
Company's Common Stock is registered under Section 12(g) of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and (ii) the Company
becomes a reporting company under the Exchange Act and the Common Stock is
authorized for quotation on The National Association of Securities Dealers, Inc.
OTC Bulletin Board. (the "Scheduled Filing Deadline"), a registration statement
on Form S-1 or SB-2 (or, if the Company is then eligible, on Form S-3) under the
Securities Act (the "Initial Registration Statement") with the SEC for the
registration for the resale by Investors who acquired Convertible Securities of
an aggregate of 1,000,000 shares of Common Stock issuable upon conversion of the
Convertible Securities. The Company shall cause the Registration Statement to
remain effective until all of the Registrable Securities have been sold or
otherwise transferred by the Investors listed on the Registration Statement as
selling stockholders pursuant to the Registration Statement or sale of the
Convertible Securities by such

                                        2
<PAGE>

could be made without limitation under Rule 144 promulgated under the Securities
Act. Prior to the filing of the Initial Registration Statement with the SEC, the
Company shall furnish a copy of the Initial Registration Statement to the
Investors, and their counsel for their review and comment. The Investors and
their counsel shall furnish comments on the Initial Registration Statement to
the Company within seventy-two (72) hours of the receipt thereof from the
Company. The Company shall consider the comments furnished by the Investors and
their counsel, but other than language specifically provided by the Investors
and full indemnification given to the Company with respect to such language in
accordance with Section 6(a) below, the Company shall have no obligation to
revise the Initial Registration Statement under this Section 2(a).

         (b) Effectiveness of the Initial Registration Statement. The Company
shall use its commercially reasonable efforts (i) to have the Initial
Registration Statement declared effective by the SEC no later than ninety (90)
days after the Scheduled Filing Deadline (the "Scheduled Effective Deadline")
and (ii) to insure that the Initial Registration Statement and any subsequent
Registration Statement remains in effect until all of the Registrable Securities
have been sold, subject to the terms and conditions of this Agreement.

         (c) Failure to File or Obtain Effectiveness of the Registration
Statement. In the event the Initial Registration Statement is not filed by the
Scheduled Filing Deadline or is not declared effective by the SEC on or before
the Scheduled Effective Date due to the failure of the Company to use its
commercially reasonable efforts, or if after the Registration Statement has been
declared effective by the SEC, sales cannot be made pursuant to the Registration
Statement (whether because of a failure to keep the Registration Statement
effective, failure to disclose such information as is necessary for sales to be
made pursuant to the Registration Statement, failure to register sufficient
shares of Common Stock or otherwise) then as partial relief for the damages to
the Investors by reason of any such delay in or reduction of their ability to
sell the underlying shares of Common Stock (which remedy shall not be exclusive
of any other remedies at law or in equity), the Company will pay as liquidated
damages (the "Liquidated Damages") to the holder a cash amount within three (3)
business days, after demand therefore, equal to two percent (2%) of (i) the
liquidated value of the Class B Preferred Stock outstanding and (ii) the
principal amount of the Debentures outstanding, as Liquidated Damages for each
thirty (30) day period after the Scheduled Filing Deadline or the Scheduled
Effective Date as the case may be.

         (d) Liquidated Damages. The Company and the Investors hereto
acknowledge and agree that the sums payable under subsection 2(c) above shall
constitute liquidated damages and not penalties. The parties further acknowledge
that (i) the amount of loss or damages likely to be incurred is incapable or is
difficult to precisely estimate, (ii) the amounts specified in such subsections
bear a reasonable relationship to, and are not plainly or grossly
disproportionate to the probable loss likely to be incurred in connection with
any failure by the Company to obtain or maintain the effectiveness of a
Registration Statement, (iii) one of the reasons for the Company and the
Investor reaching an agreement as to such amounts was the uncertainty and cost
of litigation regarding the question of actual damages, and (iv) the Company and
the Investor are sophisticated business parties.

                  3. RELATED OBLIGATIONS.

         (a) The Company shall keep the Registration Statement effective
pursuant to Rule 415 at all times until the date on which the Investors shall
have sold all the Registrable Securities covered by such Registration Statement
or otherwise transferred by the Investors listed on the Registration Statement
as selling stockholders pursuant to the Registration Statement or sale of the
Convertible Securities by such could be made without limitation under Rule 144
promulgated under the Securities Act (the "Registration Period"), which
Registration Statement (including any amendments or supplements thereto and
prospectuses contained therein) shall not (to the best of the Company's
knowledge, with respect to information regarding the Investors and the
Investor's plan of distribution, if any) contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein, or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading.

         (b) The Company shall prepare and file with the SEC such amendments
(including post-effective amendments) and supplements to the Registration
Statement and the prospectus used in connection with such Registration
Statement, which prospectus is to be filed pursuant to Rule 424 promulgated
under the Securities Act, as may be necessary to keep such Registration
Statement effective at all times during the Registration Period, and, during
such period, comply with the provisions of the Securities Act with respect to
the disposition of all Registrable Securities of the Company covered by such
Registration Statement until such time as all of such Registrable Securities
shall have been disposed of in accordance with the intended methods of
disposition by the seller or sellers thereof as set forth in such Registration
Statement. In the case of amendments and supplements to a Registration Statement
which are required to be filed pursuant to this Agreement (including pursuant to
this Section 3(b)) by reason of the Company's filing a report on Form 10-KSB,
Form 10-QSB or Form 8-K or any analogous report under the Securities Exchange
Act of 1934, as amended (the "Securities Exchange Act"), the Company shall
incorporate such report by reference into the Registration Statement, if
applicable, or shall file such amendments or supplements with the SEC on the
same day on which the Securities Exchange Act report is filed which created the
requirement for the Company to amend or supplement the Registration Statement.

         (c) The Company shall furnish to each Investor whose Registrable
Securities are included in any Registration Statement, without charge, (i) at
least one (1) copy of such Registration Statement as declared effective by the
SEC and any amendment(s) thereto, including financial statements and schedules,
all documents incorporated therein by reference, all exhibits and each
preliminary prospectus, (ii) ten (10) copies of the final prospectus included in
such Registration Statement and all amendments and supplements thereto (or such
other number of copies as such Investor may reasonably request) and (iii) such
other documents as such Investor may reasonably request from time to time in
order to facilitate the disposition of the Registrable Securities owned by such
Investor.

         (d) The Company shall use its best efforts to (i) register and qualify
the Registrable Securities covered by a Registration Statement under such other
securities or "blue sky" laws of such jurisdictions in the United States as any
Investor reasonably requests, (ii) prepare and file in those jurisdictions, such
amendments (including post-effective amendments) and supplements to such
registrations and qualifications as may be necessary to

                                        4
<PAGE>

maintain the effectiveness thereof during the Registration Period, (iii) take
such other actions as may be necessary to maintain such registrations and
qualifications in effect at all times during the Registration Period, and (iv)
take all other actions reasonably necessary or advisable to qualify the
Registrable Securities for sale in such jurisdictions; provided, however, that
the Company shall not be required in connection therewith or as a condition
thereto to (w) make any change to its certificate of incorporation or by-laws,
(x) qualify to do business in any jurisdiction where it would not otherwise be
required to qualify but for this Section 3(d), (y) subject itself to general
taxation in any such jurisdiction, or (z) file a general consent to service of
process in any such jurisdiction. The Company shall promptly notify each
Investor who holds Registrable Securities of the receipt by the Company of any
notification with respect to the suspension of the registration or qualification
of any of the Registrable Securities for sale under the securities or "blue sky"
laws of any jurisdiction in the United States or its receipt of actual notice of
the initiation or threat of any proceeding for such purpose.

         (e) As promptly as practicable after becoming aware of such event or
development, the Company shall notify each Investor in writing of the happening
of any event as a result of which the prospectus included in a Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omission to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading (provided that in no event shall such notice contain any
material, nonpublic information), and promptly prepare a supplement or amendment
to such Registration Statement to correct such untrue statement or omission, and
deliver ten (10) copies of such supplement or amendment to each Investor. The
Company shall also promptly notify each Investor in writing (i) when a
prospectus or any prospectus supplement or post-effective amendment has been
filed, and when a Registration Statement or any post-effective amendment has
become effective (notification of such effectiveness shall be delivered to each
Investor by facsimile on the same day of such effectiveness), (ii) of any
request by the SEC for amendments or supplements to a Registration Statement or
related prospectus or related information, and (iii) of the Company's reasonable
determination that a post-effective amendment to a Registration Statement would
be appropriate.

         (f) The Company shall use its best efforts to prevent the issuance of
any stop order or other suspension of effectiveness of a Registration Statement,
or the suspension of the qualification of any of the Registrable Securities for
sale in any jurisdiction within the United States of America and, if such an
order or suspension is issued, to obtain the withdrawal of such order or
suspension at the earliest possible moment and to notify each Investor who holds
Registrable Securities being sold of the issuance of such order and the
resolution thereof or its receipt of actual notice of the initiation or threat
of any proceeding for such purpose.

         (g) At the reasonable request of any Investor, the Company shall
furnish to such Investor, on the date of the effectiveness of the Registration
Statement and thereafter from time to time on such dates as an Investor may
reasonably request, in each case as of the date of the most recent prospectus or
supplement thereto, (i) a letter, dated such date, from the Company's
independent certified public accountants in form and substance as is customarily
given by independent certified public accountants to underwriters in an
underwritten public offering, and (ii) an opinion, dated as of such date, of
counsel representing the Company for

                                        5
<PAGE>

purposes of such Registration Statement, in form, scope and substance as is
customarily given in an underwritten public offering, addressed to the
Investors.

         (h) The Company shall make available for inspection by (i) any Investor
and (ii) one (1) firm of accountants or other agents retained by the Investors
as a group (collectively, the "Inspectors"), all pertinent financial and other
records, and pertinent corporate documents and properties of the Company
(collectively, the "Records"), as shall be reasonably deemed necessary by each
Inspector, and cause the Company's officers, directors and employees to supply
all information which any Inspector may reasonably request in order for the
Investors to verify the information contained in the Registration Statement
complies with the requirements of the Securities Act; provided, however, that
each Inspector shall agree, and each Investor hereby agrees, to hold in strict
confidence and shall not make any disclosure (except to an Investor) or use any
Record or other information which the Company determines in good faith to be
confidential, and of which determination the Inspectors are so notified, unless
(a) the disclosure of such Records is necessary to avoid or correct a
misstatement or omission in any Registration Statement or is otherwise required
under the Securities Act, (b) the release of such Records is ordered pursuant to
a final, non-appealable subpoena or order from a court or government body of
competent jurisdiction, or (c) the information in such Records has been made
generally available to the public other than by disclosure in violation of this
or any other agreement of which the Inspector and the Investor has knowledge.
Each Investor agrees that it shall, upon learning that disclosure of such
Records is sought in or by a court or governmental body of competent
jurisdiction or through other means, give prompt notice to the Company and allow
the Company, at its expense, to undertake appropriate action to prevent
disclosure of, or to obtain a protective order for, the Records deemed
confidential.

         (i) The Company shall hold in confidence and not make any disclosure of
information concerning an Investor provided to the Company unless (i) disclosure
of such information is necessary to comply with federal or state securities
laws, (ii) the disclosure of such information is necessary to avoid or correct a
misstatement or omission in any Registration Statement, (iii) the release of
such information is ordered pursuant to a subpoena or other final,
non-appealable order from a court or governmental body of competent
jurisdiction, or (iv) such information has been made generally available to the
public other than by disclosure in violation of this Agreement or any other
agreement. The Company agrees that it shall, upon learning that disclosure of
such information concerning an Investor is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt
written notice to such Investor and allow such Investor, at the Investor's
expense, to undertake appropriate action to prevent disclosure of, or to obtain
a protective order for, such information.

         (j) The Company shall use its best efforts either to cause all the
Registrable Securities covered by a Registration Statement (i) to be listed on
each securities exchange on which securities of the same class or series issued
by the Company are then listed, if any, if the listing of such Registrable
Securities is then permitted under the rules of such exchange or (ii) the
inclusion for quotation on the National Association of Securities Dealers, Inc.
OTC Bulletin Board for such Registrable Securities. The Company shall pay all
fees and expenses in connection with satisfying its obligation under this
Section 3(j).

                                       6
<PAGE>

         (k) The Company shall cooperate with the Investors who hold Convertible
Securities and/or Registrable Securities being offered and, to the extent
applicable, to facilitate the timely preparation and delivery of certificates
(not bearing any restrictive legend) representing the Registrable Securities to
being offered pursuant to an effective Registration Statement and enable such
certificates to be in such denominations or amounts, as the case may be, as the
Investors may reasonably request and registered in such names as the Investors
may request.

         (l) The Company shall make generally available to its security holders
as soon as practical, but not later than ninety (90) days after the close of the
period covered thereby, an earnings statement (in form complying with the
provisions of Rule 158 under the Securities Act) covering a twelve (12) month
period beginning not later than the first day of the Company's fiscal quarter
next following the effective date of the Registration Statement.

         (m) The Company shall otherwise use its best efforts to comply with all
applicable rules and regulations of the SEC in connection with any registration
hereunder.

         (n) Within two (2) business days after a Registration Statement which
covers Registrable Securities is declared effective by the SEC, the Company
shall deliver, and shall cause legal counsel for the Company to deliver, to the
transfer agent for such Registrable Securities (with copies to the Investors
whose Registrable Securities are included in such Registration Statement)
confirmation that such Registration Statement has been declared effective by the
SEC in the form attached hereto as Exhibit A.

         (o) The Company shall take all other reasonable actions necessary to
expedite and facilitate disposition by the Investors of Registrable Securities
pursuant to a Registration Statement.

                  4. OBLIGATIONS OF THE INVESTORS.

         (a) Each Investor agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in Section 3(f) or
the first sentence of 3(e), such Investor will immediately discontinue
disposition of Registrable Securities pursuant to any Registration Statement(s)
covering such Registrable Securities until such Investor's receipt of the copies
of the supplemented or amended prospectus contemplated by Section 3(e) or
receipt of notice that no supplement or amendment is required. Notwithstanding
anything to the contrary, the Company shall cause its transfer agent to deliver
unlegended certificates for shares of Common Stock to a transferee of an
Investor in accordance with the terms of the Securities Purchase Agreement in
connection with any sale of Registrable Securities with respect to which an
Investor has entered into a contract for sale prior to the Investor's receipt of
a notice from the Company of the happening of any event of the kind described in
Section 3(f) or the first sentence of 3(e) and for which the Investor has not
yet settled.

         (b) It shall be a condition precedent to the obligation of the Company
to take any action pursuant to this Agreement in respect of the securities which
are to be registered at the request of the Investors that the Investors shall
furnish to the Company such information regarding the securities held by the
Investors and the intended method of disposition thereof as

                                        7
<PAGE>

the Company shall reasonably request and as shall be required for the Company to
comply with the requirements of the Securities Act in connection with the
Registration Statement as it relates to the Investors.

                  5. EXPENSES OF REGISTRATION.

         All expenses incurred in connection with registrations, filings or
qualifications pursuant to Sections 2 and 3, including, without limitation, all
registration, listing and qualifications fees, printers, mailing expenses, legal
and accounting fees, shall be paid by the Company.

                  6. INDEMNIFICATION.

         With respect to Registrable Securities which are included in a
Registration Statement under this Agreement:

         (a) To the fullest extent permitted by law, the Company will, and
hereby does, indemnify, hold harmless and defend each Investor, the directors,
officers, partners, employees, agents, representatives of, and each Person, if
any, who controls any Investor within the meaning of the Securities Act or the
Securities Exchange Act (each, an "Indemnified Person"), against any losses,
claims, damages, liabilities, judgments, fines, penalties, charges, costs,
reasonable attorneys' fees, amounts paid in settlement or expenses, joint or
several (collectively, "Claims") incurred in investigating, preparing or
defending any action, claim, suit, inquiry, proceeding, investigation or appeal
taken from the foregoing by or before any court or governmental, administrative
or other regulatory agency, body or the SEC, whether pending or threatened,
whether or not an indemnified party is or may be a party thereto ("Indemnified
Damages"), to which any of them may become subject insofar as such Claims (or
actions or proceedings, whether commenced or threatened, in respect thereof)
arise out of or are based upon: (i) any untrue statement or alleged untrue
statement of a material fact in a Registration Statement or any post-effective
amendment thereto or in any filing made in connection with the qualification of
the offering under the securities or other "blue sky" laws of any jurisdiction
in which Registrable Securities are offered ("Blue Sky Filing"), or the omission
or alleged omission to state a material fact required to be stated therein or
necessary to make the statements therein not misleading; (ii) any untrue
statement or alleged untrue statement of a material fact contained in any final
prospectus (as amended or supplemented, if the Company files any amendment
thereof or supplement thereto with the SEC) or the omission or alleged omission
to state therein any material fact necessary to make the statements made
therein, in light of the circumstances under which the statements therein were
made, not misleading; or (iii) any violation or alleged violation by the Company
of the Securities Act, the Securities Exchange Act, any other law, including,
without limitation, any state securities law, or any rule or regulation there
under relating to the offer or sale of the Registrable Securities pursuant to a
Registration Statement (the matters in the foregoing clauses (i) through (iii)
being, collectively, "Violations"). The Company shall reimburse the Investors
and each such controlling person promptly as such expenses are incurred and are
due and payable, for any legal fees or disbursements or other reasonable
expenses incurred by them in connection with investigating or defending any such
Claim. Notwithstanding anything to the contrary contained herein, the
indemnification agreement contained in this Section 6(a): (x) shall not apply to
a Claim by an Indemnified Person arising out of or based upon a Violation which
occurs in reliance upon and in conformity with

                                        8
<PAGE>

information furnished in writing to the Company by such Indemnified Person
expressly for use in connection with the preparation of the Registration
Statement or any such amendment thereof or supplement thereto; (y) shall not be
available to the extent such Claim is based on a failure of the Investor to
deliver or to cause to be delivered the prospectus made available by the
Company, if such prospectus was timely made available by the Company pursuant to
Section 3(c); and (z) shall not apply to amounts paid in settlement of any Claim
if such settlement is effected without the prior written consent of the Company,
which consent shall not be unreasonably withheld. Such indemnity shall remain in
full force and effect regardless of any investigation made by or on behalf of
the Indemnified Person and shall survive the transfer of the Registrable
Securities by the Investors pursuant to Section 9 hereof. Notwithstanding
anything to the contrary contained herein, the indemnification agreement
contained in this Section 6(a) with respect to any prospectus shall not inure to
the benefit of any Indemnified Person if the untrue statement or omission of
material fact contained in the prospectus was corrected and such new prospectus
was delivered to each Investor prior to such Investor's use of the prospectus to
which the Claim relates.

         (b) In connection with a Registration Statement, each Investor agrees
to severally and not jointly indemnify, hold harmless and defend, to the same
extent and in the same manner as is set forth in Section 6(a), the Company, each
of its directors, each of its officers, employees, representatives, or agents
and each Person, if any, who controls the Company within the meaning of the
Securities Act or the Securities Exchange Act (each an "Indemnified Party"),
against any Claim or Indemnified Damages to which any of them may become
subject, under the Securities Act, the Securities Exchange Act or otherwise,
insofar as such Claim or Indemnified Damages arise out of or is based upon any
Violation, in each case to the extent, and only to the extent, that such
Violation occurs in reliance upon and in conformity with written information
furnished to the Company by such Investor expressly for use in connection with
such Registration Statement, including each amendment thereof or supplement
thereto; and, subject to Section 6(d), such Investor will reimburse any legal or
other expenses reasonably incurred by them in connection with investigating or
defending any such Claim; provided, however, that the indemnity agreement
contained in this Section 6(b) and the agreement with respect to contribution
contained in Section 7 shall not apply to amounts paid in settlement of any
Claim if such settlement is effected without the prior written consent of such
Investor, which consent shall not be unreasonably withheld; provided, further,
however, that the Investor shall be liable under this Section 6(b) for only that
amount of a Claim or Indemnified Damages as does not exceed the net proceeds to
such Investor as a result of the sale of Registrable Securities pursuant to such
Registration Statement. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such Indemnified Party
and shall survive the transfer of the Registrable Securities by the Investors
pursuant to Section 9.

         (c) Promptly after receipt by an Indemnified Person or Indemnified
Party under this Section 6 of notice of the commencement of any action or
proceeding (including any governmental action or proceeding) involving a Claim,
such Indemnified Person or Indemnified Party shall, if a Claim in respect
thereof is to be made against any indemnifying party under this Section 6,
deliver to the indemnifying party a written notice of the commencement thereof,
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly noticed, to assume control of

                                        9
<PAGE>

the defense thereof with counsel mutually satisfactory to the indemnifying party
and the Indemnified Person or the Indemnified Party, as the case may be;
provided, however, that an Indemnified Person or Indemnified Party shall have
the right to retain its own counsel with the fees and expenses of not more than
one (1) counsel for such Indemnified Person or Indemnified Party to be paid by
the indemnifying party, if, in the reasonable opinion of counsel retained by the
indemnifying party, the representation by such counsel of the Indemnified Person
or Indemnified Party and the indemnifying party would be inappropriate due to
actual or potential differing interests between such Indemnified Person or
Indemnified Party and any other party represented by such counsel in such
proceeding. The Indemnified Party or Indemnified Person shall cooperate fully
with the indemnifying party in connection with any negotiation or defense of any
such action or claim by the indemnifying party and shall furnish to the
indemnifying party all information reasonably available to the Indemnified Party
or Indemnified Person which relates to such action or claim. The indemnifying
party shall keep the Indemnified Party or Indemnified Person fully apprised at
all times as to the status of the defense or any settlement negotiations with
respect thereto. No indemnifying party shall be liable for any settlement of any
action, claim or proceeding effected without its prior written consent;
provided, however, that the indemnifying party shall not unreasonably withhold,
delay or condition its consent. No indemnifying party shall, without the prior
written consent of the Indemnified Party or Indemnified Person, consent to entry
of any judgment or enter into any settlement or other compromise which does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party or Indemnified Person of a release from all liability
in respect to such claim or litigation. Following indemnification as provided
for hereunder, the indemnifying party shall be subrogated to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms
or corporations relating to the matter for which indemnification has been made.
The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall not relieve such
indemnifying party of any liability to the Indemnified Person or Indemnified
Party under this Section 6, except to the extent that the indemnifying party is
prejudiced in its ability to defend such action.

         (d) The indemnification required by this Section 6 shall be made by
periodic payments of the amount thereof during the course of the investigation
or defense, as and when bills are received or Indemnified Damages are incurred.

         (e) The indemnity agreements contained herein shall be in addition to
(i) any cause of action or similar right of the Indemnified Party or Indemnified
Person against the indemnifying party or others, and (ii) any liabilities the
indemnifying party may be subject to pursuant to the law.

                  7. CONTRIBUTION.

         To the extent any indemnification by an indemnifying party is
prohibited or limited by law, the indemnifying party agrees to make the maximum
contribution with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no seller of Registrable Securities guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any seller of Registrable Securities or the Company who or
which was not

                                       10
<PAGE>

guilty of fraudulent misrepresentation; and (ii) contribution by any seller of
Registrable Securities shall be limited in amount to the net amount of proceeds
received by such seller from the sale of such Registrable Securities.

                  8. REPORTS UNDER THE SECURITIES EXCHANGE ACT.

         With a view to making available to the Investors the benefits of Rule
144 promulgated under the Securities Act or any similar rule or regulation of
the SEC that may at any time permit the Investors to sell securities of the
Company to the public without registration ("Rule 144"), the Company agrees to:

         (a) make and keep public information available, as those terms are
understood and defined in Rule 144;

         (b) file with the SEC in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act
so long as the Company remains subject to such requirements and the filing of
such reports and other documents as are required by the applicable provisions of
Rule 144; and

         (c) furnish to each Investor so long as such Investor owns Registrable
Securities, promptly upon request, (i) a written statement by the Company that
it has complied with the reporting requirements of Rule 144, the Securities Act
and the Securities Exchange Act, (ii) 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 (iii) such other information as may be reasonably requested to
permit the Investors to sell such securities pursuant to Rule 144 without
registration.

                  9. ASSIGNMENT OF REGISTRATION RIGHTS.

         The rights under this Agreement shall be automatically assignable by
the Investors to any transferee of all or any portion of Registrable Securities
if: (i) the Investor agrees in writing with the transferee or assignee to assign
such rights, and a copy of such agreement is furnished to the Company within a
reasonable time after such assignment; (ii) the Company is, within a reasonable
time after such transfer or assignment, furnished with written notice of (a) the
name and address of such transferee or assignee, and (b) the securities with
respect to which such registration rights are being transferred or assigned; and
(iii) at or before the time the Company receives the written notice contemplated
by clause (ii) of this sentence the transferee or assignee agrees in writing
with the Company to be bound by all of the provisions contained herein as an
Investor.

                  10. AMENDMENT OF REGISTRATION RIGHTS.

         Provisions of this Agreement may be amended and the observance thereof
may be waived (either generally or in a particular instance and either
retroactively or prospectively), only with the written consent of the Company
and Investors who then hold at least two-thirds (2/3) of the Registrable
Securities, on an as converted basis. Any amendment or waiver effected in
accordance with this Section 10 shall be binding upon each Investor and the
Company. No such amendment shall be effective to the extent that it applies to
fewer than all of the holders of the Registrable Securities. No consideration
shall be offered or paid to any Investor to amend or

                                       11
<PAGE>

consent to a waiver or modification of any provision of any of this Agreement
unless the same consideration also is offered to all of the Investors who are
party to this Agreement.

                  11. MISCELLANEOUS.

         (a) A Person is deemed to be a holder of Registrable Securities
whenever such Person owns or is deemed to own of record such Registrable
Securities. If the Company receives conflicting instructions, notices or
elections from two (2) or more Persons with respect to the same Registrable
Securities, the Company shall act upon the basis of instructions, notice or
election received from the registered owner of such Registrable Securities.

         (b) All notices or other communications required or permitted to be
given pursuant to this Agreement shall be in writing and shall be considered as
duly given on: (a) the date of delivery, if delivered in person against written
receipt therefor, or by nationally recognized overnight delivery service or (b)
five (5) days after mailing if mailed from within the continental United States
by postage pre-paid certified mail, return receipt requested to the party
entitled to receive the same:

Investors attached hereto, with copies to such Investor's representatives as set
forth on the Schedule of Investors or to such other address and/or facsimile
number and/or to the attention of such other person as the recipient party has
specified by written notice given to each other party five (5) days prior to the
effectiveness of such change. Written confirmation of receipt (A) given by the

with clause (i), (ii) or (iii) above, respectively.

         (c) Failure of any party to exercise any right or remedy under this
Agreement or otherwise, or delay by a party in exercising such right or remedy,
shall not operate as a waiver thereof.

         (d) The laws of the State of New Jersey shall govern all issues
concerning the relative rights of the Company and the Investors as its
stockholders. All other questions concerning the construction, validity,
enforcement and interpretation of this Agreement shall be governed by the
internal laws of the State of New Jersey, without giving effect to any choice of
law or conflict of law provision or rule (whether of the State of New Jersey or
any other jurisdiction) that would cause the application of the laws of any
jurisdiction other than the State of New Jersey. Each party hereby irrevocably
submits to the non-exclusive jurisdiction of the Superior Courts of the State of
New Jersey, sitting in Hudson County, New Jersey and federal courts for the
District of New Jersey sitting in Newark, New Jersey, for the adjudication of
any dispute hereunder or in connection herewith or with any transaction
contemplated hereby or discussed herein, and hereby irrevocably waives, and
agrees not to assert in any suit, action or proceeding, any claim that it is not
personally subject to the jurisdiction of any such court, that such suit, action
or proceeding is brought in an inconvenient forum or that the venue of such
suit, action or proceeding is improper. Each party hereby irrevocably waives
personal service of process and consents to process being served in any such
suit, action or proceeding by mailing a copy thereof to such party at the
address for such notices to it under this Agreement and agrees that such service
shall constitute good and sufficient service of process and notice thereof.
Nothing contained herein shall be deemed to limit in any way any right to serve
process in any manner permitted by law. If any provision of this Agreement shall
be invalid or unenforceable in any jurisdiction, such invalidity or
unenforceability shall not affect the validity or enforceability of the
remainder of this Agreement in that jurisdiction or the validity or
enforceability of any provision of this Agreement in any other jurisdiction.
EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO
REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN
CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION
CONTEMPLATED HEREBY.

         (e) This Agreement, together with that certain Agreement and Plan of
Merger entered into as of the date hereof, by an among the Company, iVoice, and
each of the

                                       13
<PAGE>

other parties named therein (the "Merger Agreement"), each Transaction Document
(as defined in the Merger Agreement), the Convertible Debentures, Security
Agreement and related documents including that certain Escrow Agreement dated
the date hereof by and among the Company and certain of its shareholders (the
"Escrow Agreement") constitute the entire agreement among the parties hereto
with respect to the subject matter hereof and thereof. There are no
restrictions, promises, warranties or undertakings, other than those set forth
or referred to herein and therein. This Agreement, the Merger Agreement, the
Transaction Documents and the Convertible Debentures and related documents
including the Escrow Agreement supersede all prior agreements and understandings
among the parties hereto with respect to the subject matter hereof and thereof.

         (f) This Agreement shall inure to the benefit of and be binding upon
the permitted successors and assigns of each of the parties hereto.

         (g) The headings in this Agreement are for convenience of reference
only and shall not limit or otherwise affect the meaning hereof.

         (h) This Agreement may be executed in identical counterparts, each of
which shall be deemed an original but all of which shall constitute one and the
same agreement. This Agreement, once executed by a party, may be delivered to
the other party hereto by facsimile transmission of a copy of this Agreement
bearing the signature of the party so delivering this Agreement.

         (i) Each party shall do and perform, or cause to be done and performed,
all such further acts and things, and shall execute and deliver all such other
agreements, certificates, instruments and documents, as the other party may
reasonably request in order to carry out the intent and accomplish the purposes
of this Agreement and the consummation of the transactions contemplated hereby.

         (j) The language used in this Agreement will be deemed to be the
language chosen by the parties to express their mutual intent and no rules of
strict construction will be applied against any party.

         (k) If any term or other provision of this Agreement is invalid,
illegal or incapable of being enforced by any rule of law or public policy, all
other conditions and provisions of this Agreement shall nevertheless remain in
full force and effect so long as the economic or legal substance of the
transactions contemplated hereby is not affected in any manner adverse to any
party. Upon a determination that any term or other provision is invalid, illegal
or incapable of being enforced, the parties hereto shall negotiate in good faith
to modify this Agreement so as to effect the original intent of the parties as
closely as possible in an acceptable manner to the end that the transactions
contemplated hereby are fulfilled to the extent possible.

         (l) This Agreement is intended for the benefit of the parties hereto
and their respective permitted successors and assigns, and is not for the
benefit of, nor may any provision hereof be enforced by, any other Person.
