third party shall be entitled to a "windfall" (i.e., a benefit they would not be
entitled to receive in the absence of the indemnification provisions) by virtue
of the indemnification provisions hereof. Nothing contained in this Agreement,
any Ancillary Agreement or the Tax Agreement shall obligate any member of any
Group to seek to collect or recover any Insurance Proceeds.

     5.5.  PROCEDURES FOR INDEMNIFICATION OF THIRD PARTY CLAIMS. (a) If an
Indemnitee shall receive notice or otherwise learn of the assertion by a Person
(including any Governmental Authority) who is not a member of the IDT Group or
the Net2Phone Group of any claim or of the commencement by any such Person of
any Action (collectively, a "Third Party Claim") with respect to which an
Indemnifying

                                       10
<PAGE>

Party may be obligated to provide indemnification to such Indemnitee pursuant to
Section 5.2 or 5.3, or any other Section of this Agreement, any Ancillary
Agreement or the Tax Agreement, such Indemnitee shall give such Indemnifying
Party written notice thereof within 20 days after becoming aware of such Third
Party Claim. Any such notice shall describe the Third Party Claim in reasonable
detail. Notwithstanding the foregoing, the failure of any Indemnitee or other
Person to give notice as provided in this Section 5.5(a) shall not relieve the
related Indemnifying Party of its obligations under this Article V, except to
the extent that such Indemnifying Party is actually prejudiced by such failure
to give notice.

     (b) An Indemnifying Party may elect to defend (and, unless the Indemnifying
Party has specified any reservations or exceptions, to seek to settle or
compromise), at such Indemnifying Party's own expense and by such Indemnifying
Party's own counsel, any Third Party Claim. Within 30 days after the receipt of
notice from an Indemnitee in accordance with Section 5.5(a) (or sooner, if the
nature of such Third Party Claim so requires), the Indemnifying Party shall
notify the Indemnitee of its election whether the Indemnifying Party will assume
responsibility for defending such Third Party Claim, which election shall
specify any reservations or exceptions. After notice from an Indemnifying Party
to an Indemnitee of its election to assume the defense of a Third Party Claim,
such Indemnitee shall have the right to employ separate counsel and to
participate in (but not control) the defense, compromise, or settlement thereof,
but the fees and expenses of such counsel shall be the expense of such
Indemnitee except as set forth in the next sentence. In the event that the
Indemnifying Party has elected to assume the defense of the Third Party Claim
but has specified, and continues to assert, any reservations or exceptions in
such notice, then, in any such case, the reasonable fees and expenses of one
separate counsel for all Indemnitees shall be borne by the Indemnifying Party.

     (c) If an Indemnifying Party elects not to assume responsibility for
defending a Third Party Claim, or fails to notify an Indemnitee of its election
as provided in Section 5.5(b), such Indemnitee may defend such Third Party Claim
at the cost and expense of the Indemnifying Party.

     (d) Unless the Indemnifying Party has failed to assume the defense of the
Third Party Claim in accordance with the terms of this Agreement, no Indemnitee
may settle or compromise any Third Party Claim without the consent of the
Indemnifying Party, which consent shall not be unreasonably withheld.

     (e) No Indemnifying Party shall consent to entry of any judgment or enter
into any settlement of the Third Party Claim without the consent of the
Indemnitee if the effect thereof is to permit any injunction, declaratory
judgment, other order or other nonmonetary relief to be entered, directly or
indirectly, against any Indemnitee.

     (f) The provisions of Section 5.5 and Section 5.6 shall not apply to Taxes
(which are covered by the Tax Agreement).

     5.6.  ADDITIONAL MATTERS. (a) Any claim on account of a Liability which

                                       11
<PAGE>

does not result from a Third Party Claim shall be asserted by written notice
given by the Indemnitee to the related Indemnifying Party. Such Indemnifying
Party shall have a period of 30 days after the receipt of such notice within
which to respond thereto. If such Indemnifying Party does not respond within
such 30-day period, such Indemnifying Party shall be deemed to have refused to
accept responsibility to make payment. If such Indemnifying Party does not
respond within such 30-day period or rejects such claim in whole or in part,
such Indemnitee shall be free to pursue such remedies as may be available to
such party as contemplated by this Agreement, the Ancillary Agreements and the
Tax Agreement.

     (b) In the event of payment by or on behalf of any Indemnifying Party to
any Indemnitee in connection with any Third Party Claim, such Indemnifying Party
shall be subrogated to and shall stand in the place of such Indemnitee as to any
events or circumstances in respect of which such Indemnitee may have any right,
defense or claim relating to such Third Party Claim against any claimant or
plaintiff asserting such Third Party Claim or against any other person. Such
Indemnitee shall cooperate with such Indemnifying Party in a reasonable manner,
and at the cost and expense (including allocated costs of in-house counsel and
other personnel) of such Indemnifying Party, in prosecuting any subrogated
right, defense or claim.

     (c) In the event of an Action in which the Indemnifying Party is not a
named defendant, if the Indemnifying Party shall so request, the parties shall
endeavor to substitute the Indemnifying Party for the named defendant if at all
practicable. If such substitution or addition cannot be achieved for any reason
or is not requested, the named defendant shall allow the Indemnifying Party to
manage the Action as set forth in this Section and the Indemnifying Party shall
fully indemnify the named defendant against all costs of defending the Action
(including court costs, sanctions imposed by a court, attorneys' fees, experts'
fees and all other external expenses), the costs of any judgment or settlement,
and the cost of any interest or penalties relating to any judgment or
settlement.

     5.7.  REMEDIES CUMULATIVE.  The remedies provided in this Article V shall
be cumulative and, subject to the provisions of Article VIII, shall not preclude
assertion by any Indemnitee of any other rights or the seeking of any and all
other remedies against any Indemnifying Party.

     5.8.  SURVIVAL OF INDEMNITIES.  The rights and obligations of each of IDT
and Net2Phone and their respective Indemnitees under this Article V shall
survive the sale or other transfer by any party of any Assets or businesses or
the assignment by it of any Liabilities.

     5.9   UNAVAILABILITY OF INDEMNITY.  If the indemnification provided for in
this Article V is held by a court of competent jurisdiction to be unavailable to
an indemnified party with respect to any Liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party hereunder,
agrees to contribute to the amount paid or payable by such indemnified party as
a result of such Liability in such proportion as is appropriate to reflect the
relative fault of the indemnifying party on one

                                       12
<PAGE>

hand and of the indemnified party on the other in connection with the event that
resulted in such Liability, as well as any other relevant equitable
considerations.

                                   ARTICLE VI
                      OPERATIONS AND CERTAIN OTHER MATTERS

     6.1.  INSURANCE MATTERS. (a)  Net2Phone and IDT contemplate that Net2Phone
shall obtain its own Directors and Officers Insurance Policy in a timely manner
following the sale of equity to new investors.  Each of Net2Phone and IDT agree
that Net2Phone may remain on IDT's insurance policies relating to property,
errors and omissions, professional liability, automobile and general liability
until the earlier of such time as Net2Phone no longer qualifies for coverage on
the respective IDT Insurance Policy or, upon thirty (30) days' prior written
notice to IDT, Net2Phone elects to be removed from the IDT Insurance Policy or
Policies.  For so long as Net2Phone is covered by IDT's Insurance Policies,
Net2Phone will pay to IDT each month (prorated on a daily basis for any partial
month) in respect of the period from the date hereof until the termination of
Net2Phone's coverage on all of IDT's Insurance Policies the amount calculated as
set forth on Exhibit B hereto, such amount to be payable in arrears by the 10th
             ---------                                                        
day of the next succeeding month, in respect of Insurance Policies under which
Net2Phone will continue to have coverage following the date hereof.  IDT and
Net2Phone agree to cooperate in good faith to provide for the treatment of any
Insurance Policies that will remain in effect following the date hereof on a
mutually agreeable basis.  IDT shall provide Net2Phone with prompt notice in the
event that any Insurance Policy shall be terminated or otherwise cease to be in
effect for any reason.  In no event shall IDT, any other member of the IDT Group
or any IDT Indemnitee have liability or obligation whatsoever to any member of
the Net2Phone Group in the event (i) that any Insurance Policy or other contract
or policy of insurance shall be terminated or otherwise cease to be in effect
for any reason, shall be unavailable or inadequate to cover any Liability of any
member of the Net2Phone Group for any reason whatsoever or shall not be renewed
or extended beyond the current expiration date. or (ii) notwithstanding the
provisions of the immediately preceding sentence, that IDT fails to provide
Net2Phone with notice of any such event.

     (b) (i)  Except as otherwise provided in any Ancillary Agreement, the
parties intend by this Agreement that Net2Phone and each other member of the
Net2Phone Group be successors-in-interest to all rights that any member of the
Net2Phone Group may have as of the date hereof as a subsidiary, affiliate,
division or department of IDT prior to the date hereof under any policy of
insurance issued to IDT by any insurance carrier unaffiliated with IDT or under
any agreements related to such policies executed and delivered prior to the date
hereof, including any rights such member of the Net2Phone Group may have, as an
insured or additional named insured, subsidiary, affiliate, division or
department, to avail itself of any such policy of insurance or any such
agreements related to such policies as in effect prior to the date hereof. At
the request of Net2Phone, IDT shall take all reasonable steps, including the
execution and delivery of any instruments, to effect the foregoing; provided,
however that IDT shall not be required to pay any amounts, waive any rights or
incur any Liabilities in connection therewith.

                                       13
<PAGE>

     (ii) Except as otherwise contemplated by any Ancillary Agreement, after the
date hereof, none of IDT or Net2Phone or any member of their respective Groups
shall, without the consent of the other, provide any such insurance carrier with
a release, or amend, modify or waive any rights under any such policy or
agreement, if such release, amendment, modification or waiver would adversely
affect any rights or potential rights of any member of the other Group
thereunder; provided however that the foregoing shall not (A) preclude any
member of any Group from presenting any claim or from exhausting any policy
limit, (B) require any member of any Group to pay any premium or other amount or
to incur any Liability, or (C) require any member of any Group to renew, extend
or continue any policy in force. Each of Net2Phone and IDT will share such
information as is reasonably necessary in order to permit the other to manage
and conduct its insurance matters in an orderly fashion.

     (c) This Agreement shall not be considered as an attempted assignment of
any policy of insurance or as a contract of insurance and shall not be construed
to waive any right or remedy of any member of the IDT Group in respect of any
Insurance Policy or any other contract or policy of insurance.

     (d) Net2Phone does hereby, for itself and each other member of the
Net2Phone Group, agree that no member of the IDT Group or any IDT Indemnitee
shall have any Liability whatsoever as a result of the insurance policies and
practices of IDT and its Affiliates as in effect at any time prior to the date
hereof, including as a result of the level or scope of any such insurance, the
creditworthiness of any insurance carrier, the terms and conditions of any
policy, the adequacy or timeliness of any notice to any insurance carrier with
respect to any claim or potential claim or otherwise.

     (e) Nothing in this Agreement shall be deemed to restrict any member of the
Net2Phone Group from acquiring at its own expense any other insurance policy in
respect of any Liabilities or covering any period.

     6.2.  CERTAIN BUSINESS MATTERS. (a) Except as may be expressly set forth in
Section 6.3 below or in any Ancillary Agreement, no member of any Group shall
have any duty to refrain from (i) engaging in the same or similar activities or
lines of business as any member of any other Group, (ii) doing business with any
potential or actual supplier or customer of any member of any other Group, or
(iii) engaging in, or refraining from, any other activities whatsoever relating
to any of the potential or actual suppliers or customers of any member of any
other Group.

     (b) Each of IDT and Net2Phone is aware that from time to time certain
business opportunities may arise which more than one Group may be financially
able to undertake, and which are, from their nature, in the line of more than
one Group's business and are of practical advantage to more than one Group. In
connection therewith, the parties agree that if, following the date hereof, any
of IDT or Net2Phone acquires knowledge of an opportunity that meets the
foregoing standard with respect to more than one Group, none of the IDT Group or
the Net2Phone Group shall have any duty to communicate or offer such opportunity
to any of the others and may pursue or acquire such opportunity for itself, or
direct such opportunity to any other Person.

                                       14

     6.3.  NON-COMPETITION.

     (a) IDT acknowledges that as the Parent of Net2Phone it and its Affiliates
have become privy to certain confidential information and trade secrets of
Net2Phone and further acknowledges that it will derive substantial benefits from
the separation of IDT and Net2Phone and that purchasers of equity of Net2Phone
will be making substantial investments in reliance upon the agreement contained
in this Section 6.3 that the knowledge and expertise developed by Net2Phone and
available to IDT will be preserved and will not be used in competition with
Net2Phone. IDT hereby agrees that it is reasonable and necessary for the
protection of Net2Phone that it agree, and accordingly IDT hereby does agree
that, for a period of 36 months from the date hereof (the "Noncompetition
Period"), neither IDT nor any member of the IDT Group will directly or
indirectly, alone or in association with any other person, corporation, firm or
business, engage in the Net2Phone Business any where in the world or become a
stockholder, partner or owner of any other person, corporation, firm or business
that is primarily engaged in the Net2Phone Business any where in the world;
provided, however, that subject to Net2Phone's prior approval which shall not be
-----------------                                                              
unreasonably withheld, IDT or a member of the IDT Group may acquire a passive
investment of up to 20% of another entity so long as IDT or such member of the
IDT Group does not assist that entity in developing an Internet telephony
business or otherwise engaging in the Net2Phone Business.

     (b) For a period of 36 months from the date hereof, neither IDT nor
Net2Phone, nor any member of either such party's affiliated group, shall,
whether for its own account or for the account of any other person, corporation,
firm or business (other than Net2Phone or its Affiliates), solicit or endeavor
to entice away from the other party, or otherwise interfere with the
relationship of such other party with, any person who or which is employed on
the date hereof by, or otherwise engaged to perform services for, the other
party (including, but not limited to, any independent contractors or
organizations), except to the extent that such other party agrees to release
such employee or other service provider to the other party or such other party's
affiliated group.  General advertising for employment positions or general
employment searches through a third party recruiter are not covered by this
Section 6.3(b).

     (c) IDT expressly agrees that the covenants contained in Section 6.3(a) and
Section 6.3(b) are reasonable and necessary for the protection of Net2Phone.
The provisions of such Section 6.3(a) and Section 6.3(b) are separate and
distinct commitments independent of each of the other provisions of such
Sections.  The invalidity or non-enforceability of this Section 6.3 in any
respect shall not affect the validity or enforceability of this Section 6.3 in
any other respect or of any other provisions of this Agreement. In the event
that any provision of this Section 6.3 shall be held invalid or unenforceable by
a court of competent jurisdiction by reason of the geographic or business scope
or the duration thereof, such invalidity or unenforceability shall attach only
to the scope or duration of such provision and shall not affect or render
invalid or unenforceable any other provision of this Agreement, and, to the
fullest extent permitted by law, this Agreement shall be construed as if the
geographic or business scope or the duration of such provision had been more
narrowly drafted so as not to be

                                       15
<PAGE>

invalid or unenforceable.

     (d) IDT acknowledges that Net2Phone would suffer irreparable harm if IDT
were to breach the provisions of this Section 6.3 and that Net2Phone's remedy at
law for any such breach is and will be insufficient and inadequate and that
Net2Phone shall be entitled to equitable relief, including by way of temporary
and permanent injunction, in addition to any remedies Net2Phone may have at law.

     6.4.  LATE PAYMENTS.  Except as expressly provided to the contrary in this
Agreement or in any Ancillary Agreement, any amount not paid when due pursuant
to this Agreement, any Ancillary Agreement or the Tax Agreement shall accrue
interest at a rate per annum equal to the Prime Rate plus 2% commencing upon the
later of the (a) due date of such amount and (b) thirtieth day following such
amount being invoiced or otherwise demanded in writing.


                                  ARTICLE VII
                    EXCHANGE OF INFORMATION; CONFIDENTIALITY

     7.1.  AGREEMENT FOR EXCHANGE OF INFORMATION; ARCHIVES. (a) Each of IDT and
Net2Phone, on behalf of its respective Group, agrees to provide, or cause to be
provided, to the other Group, as soon as reasonably practicable after written
request therefor, any Information in the possession or under the control of such
Group which the requesting party reasonably needs (i) to comply with reporting,
disclosure, filing or other requirements imposed on the requesting party
(including under applicable securities or tax laws) by a Governmental Authority
having jurisdiction over the requesting party, (ii) for use in any other
judicial, regulatory, administrative, tax or other proceeding or in order to
satisfy audit, accounting, claims, regulatory, litigation, tax or other similar
requirements, or (iii) to comply with its obligations under this Agreement or
any Ancillary Agreement; provided, however, that in the event that any party
determines that any such provision of Information could be commercially
detrimental, violate any law or agreement, or waive any attorney client
privilege, the parties shall take all reasonable measures to permit the
compliance with such obligations in a manner that avoids any such harm or
consequence.

     (b) Net2Phone shall have access during regular business hours (as in effect
from time to time) to the documents and objects of historic significance that
relate to the business of Net2Phone that are located in the IDT Records to the
extent such documents or objects have been specifically identified and requested
by Net2Phone in advance or, if specific documents or objects have not been
identified, to the extent Net2Phone has provided IDT with proper advance notice
to request such access and the Net2Phone representative designated to receive
such access is accompanied by an IDT representative.  Net2Phone may obtain
copies (but not originals) of documents for bona fide business purposes and may
obtain objects for exhibition purposes for commercially reasonable periods of
time if required for bona fide business purposes, provided that Net2Phone shall
cause any such objects to be returned promptly in the same condition in which
they were delivered to Net2Phone and Net2Phone shall comply with any rules,

                                       16
<PAGE>

procedures or other requirements, and shall be subject to any restrictions
(including prohibitions on removal of specified objects), that are then
applicable to IDT.  Nothing herein shall be deemed to restrict the access of any
member of the IDT Group to any such documents or objects or to impose any
liability on any member of the IDT Group if any such documents or objects are
not maintained or preserved by IDT.

     (c) After the date hereof, (i) Net2Phone shall maintain in effect at its
own cost and expense adequate systems and controls to the extent necessary to
enable the members of the IDT Group to satisfy their respective reporting,
accounting, audit and other obligations, and (ii) Net2Phone shall in a timely
manner provide, or cause to be provided, to IDT in such form as IDT shall
request, at no charge to IDT, all financial and other data and information as
IDT determines necessary or advisable in order to prepare IDT financial
statements and reports or filings with any Governmental Authority.

     7.2.  OWNERSHIP OF INFORMATION.  Any Information owned by one Group that is
provided to a requesting party pursuant to Section 7.1 shall be deemed to remain
the property of the providing party.  Unless specifically set forth herein,
nothing contained in this Agreement shall be construed as granting or conferring
rights of license or otherwise in any such Information.

     7.3.  COMPENSATION FOR PROVIDING INFORMATION.  The party requesting such
Information agrees to reimburse the other party for the reasonable costs, if
any, of creating, gathering and copying such Information, to the extent that
such costs are incurred for the benefit of the requesting party.  Except as may
be otherwise specifically provided elsewhere in this Agreement or in any other
agreement between the parties, such costs shall be computed in accordance with
the providing party's standard methodology and procedures.

     7.4.  RECORD RETENTION. To facilitate the possible exchange of Information
pursuant to this Article VII and other provisions of this Agreement after the
date hereof, the parties agree to use their reasonable best efforts to retain
all Information in their respective possession or control on the date hereof in
accordance with the policies of IDT as in effect on the date hereof.  No party
will destroy, or permit any of its Subsidiaries to destroy, any Information
which the other party may have the right to obtain pursuant to this Agreement
prior to the third anniversary of the date hereof without first using its
reasonable best efforts to notify the other party of the proposed destruction
and giving the other party the opportunity to take possession of such
information prior to such destruction; provided, however, that in the case of
any Information relating to Taxes or to Environmental Liabilities, such period
shall be extended to the expiration of the applicable statute of limitations
(giving effect to any extensions thereof).

     7.5.  LIMITATION OF LIABILITY.  No party shall have any liability to any
other party in the event that any Information exchanged or provided pursuant to
this Agreement which is an estimate or forecast, or which is based on an
estimate or forecast, is found to be inaccurate, in the absence of willful
misconduct by the party providing such Information.  No party shall have any
liability to any other party if any Information is destroyed after reasonable
best efforts by such party to comply with the provisions of

                                       17
<PAGE>

Section 7.4.

     7.6.  OTHER AGREEMENTS PROVIDING FOR EXCHANGE OF INFORMATION. The rights
and obligations granted under this Article VII are subject to any specific
limitations, qualifications or additional provisions on the sharing, exchange or
confidential treatment of Information set forth in any Ancillary Agreement.

     7.7.  PRODUCTION OF WITNESSES; RECORDS; COOPERATION. (a) After the date
hereof, except in the case of an adversarial Action by one party against another
party, each party hereto shall use its reasonable best efforts to make available
to each other party, upon written request, the former, current and future
directors, officers, employees, other personnel and agents of the members of its
respective Group as witnesses and any books, records or other documents within
its control or which it otherwise has the ability to make available, to the
extent that any such person (giving consideration to business demands of such
directors, officers, employees, other personnel and agents) or books, records or
other documents may reasonably be required in connection with any Action in
which the requesting party may from time to time be involved, regardless of
whether such Action is a matter with respect to which indemnification may be
sought hereunder. The requesting party shall bear all costs and expenses in
connection therewith.

     (b) If an Indemnifying Party chooses to defend or to seek to compromise or
settle any Third Party Claim, the other parties shall make available to such
Indemnifying Party or such other party, as the case may be, upon written
request, the former, current and future directors, officers, employees, other
personnel and agents of the members of its respective Group as witnesses and any
books, records or other documents within its control or which it otherwise has
the ability to make available, to the extent that any such person (giving
consideration to business demands of such directors, officers, employees, other
personnel and agents) or books, records or other documents may reasonably be
required in connection with such defense, settlement or compromise, or such
prosecution, evaluation or pursuit, as the case may be, and shall otherwise
cooperate in such defense, settlement or compromise, or such prosecution,
evaluation or pursuit, as the case may be.

     (c) Without limiting the foregoing, the parties shall cooperate and consult
to the extent reasonably necessary with respect to any Actions.

     (d) Without limiting any provision of this Section, each of the parties
agrees to cooperate, and to cause each member of its respective Group to
cooperate, with each other in the defense of any infringement or similar claim
with respect to any intellectual property and shall not claim to acknowledge, or
permit any member of its respective Group to claim to acknowledge, the validity
or infringing use of any intellectual property of a third Person in a manner
that would hamper or undermine the defense of such infringement or similar
claim.

     (e) The obligation of the parties to provide witnesses pursuant to this
Section 7.7 is intended to be interpreted in a manner so as to facilitate
cooperation and shall include the obligation to provide as witnesses inventors
and other officers without regard

                                       18
<PAGE>

to whether the witness or the employer of the witness could assert a possible
business conflict (subject to the exception set forth in the first sentence of
Section 7.7(a)).

     (f) In connection with any matter contemplated by this Section 7.7, the
parties will enter into a mutually acceptable joint defense agreement so as to
maintain to the extent practicable any applicable attorney-client privilege or
work product immunity of any member of any Group.

     7.8.  CONFIDENTIALITY.  (a) Subject to Section 7.9, each of IDT and
Net2Phone, on behalf of itself and each member of its respective Group, agrees
to hold, and to cause its respective directors, officers, employees, agents,
accountants, counsel and other advisors and representatives to hold, in strict
confidence, with at least the same degree of care that applies to IDT's
confidential and proprietary information pursuant to policies in effect as of
the date hereof, all Information concerning each such other Group that is either
in its possession (including Information in its possession prior to either of
the date hereof) or furnished by any such other Group or its respective
directors, officers, employees, agents, accountants, counsel and other advisors
and representatives at any time pursuant to this Agreement, any Ancillary
Agreement, the Tax Agreement or otherwise, and shall not use any such
Information other than for such purposes as shall be expressly permitted
hereunder or thereunder, except, in each case, to the extent that such
Information has been (i) in the public domain through no fault of such party or
any member of such Group or any of their respective directors, officers,
employees, agents, accountants, counsel and other advisors and representatives,
(ii) later lawfully acquired from other sources by such party (or any member of
such party's Group) which sources are not themselves bound by a confidentiality
obligation), or (iii) independently generated without reference to any
proprietary or confidential Information of the other party.

     (b) Each party agrees not to release or disclose, or permit to be released
or disclosed, any such Information to any other Person, except its directors,
officers, employees, agents, accountants, counsel and other advisors and
representatives who need to know such Information (who shall be advised of their
obligations hereunder with respect to such Information), except in compliance
with Section 7.9.  Without limiting the foregoing, when any Information is no
longer needed for the purposes contemplated by this Agreement, any Ancillary
Agreement, or the Tax Agreement, each party will promptly after request of the
other party either return to the other party all Information in a tangible form
(including all copies thereof and all notes, extracts or summaries based
thereon) or certify to the other party that it has destroyed such Information
(and such copies thereof and such notes, extracts or summaries based thereon).

     7.9.  PROTECTIVE ARRANGEMENTS.  In the event that any party or any member
of its Group either determines on the advice of its counsel that it is required
to disclose any Information pursuant to applicable law or receives any demand
under lawful process or from any Governmental Authority to disclose or provide
Information of any other party (or any member of any other party's Group) that
is subject to the confidentiality provisions hereof, such party shall notify the
other party prior to disclosing or providing such Information and shall
cooperate at the expense of the requesting party in seeking any reasonable
protective arrangements requested by such

                                       19
<PAGE>

other party. Subject to the foregoing, the Person that received such request may
thereafter disclose or provide Information to the extent required by such law
(as so advised by counsel) or by lawful process or such Governmental Authority.

                                  ARTICLE VIII
                        ARBITRATION; DISPUTE RESOLUTION

     8.1.  AGREEMENT TO ARBITRATE.  Except as otherwise specifically provided in
any Ancillary Agreement, the procedures for discussion, negotiation and
arbitration set forth in this Article VIII shall apply to all disputes,
controversies or claims (whether sounding in contract, tort or otherwise) that
may arise out of or relate to, or arise under or in connection with this
Agreement or any Ancillary Agreement, or the transactions contemplated hereby or
thereby (including all actions taken in furtherance of the transactions
contemplated hereby or thereby on or prior to the date hereof), or the
commercial or economic relationship of the parties relating hereto or thereto,
between or among any member of the IDT Group and the Net2Phone Group.  Each
party agrees on behalf of itself and each member of its respective Group that
the procedures set forth in this Article VIII shall be the sole and exclusive
remedy in connection with any dispute, controversy or claim relating to any of
the foregoing matters and irrevocably waives any right to commence any Action in
or before any Governmental Authority, except as expressly provided in Sections
8.7(b) and 8.8 and except to the extent provided under the Arbitration Act in
the case of judicial review of arbitration results or awards.  Each party on
behalf of itself and each member of its respective Group irrevocably waives any
right to any trial by jury with respect to any claim, controversy or dispute set
forth in the first sentence of this Section 8.1.

     8.2.  ESCALATION.  (a) It is the intent of the parties to use their
respective reasonable best efforts to resolve expeditiously any dispute,
controversy or claim between or among them with respect to the matters covered
hereby that may arise from time to time on a mutually acceptable negotiated
basis. In furtherance of the foregoing, any party involved in a dispute,
controversy or claim shall deliver a notice (an "Escalation Notice") demanding
an in-person meeting involving representatives of the parties at a senior level
of management of the parties (or if the parties agree, of the appropriate
strategic business unit or division within such entity). A copy of any such
Escalation Notice shall be given to the Chief Financial Officer, or like officer
or official, of each party involved in the dispute, controversy or claim (which
copy shall state that it is an Escalation Notice pursuant to this Agreement).
Any agenda, location or procedure for such discussions or negotiations between
the parties may be established by the parties from time to time; provided,
however, that the parties shall use their reasonable best efforts to meet within
30 days of the Escalation Notice.

     (b) The parties may, by mutual consent, retain a mediator to aid the
parties in their discussions and negotiations by informally providing advice to
the parties.  Any opinion expressed by the mediator shall be strictly advisory
and shall not be binding on the parties, nor shall any opinion expressed by the
mediator be admissible in any arbitration proceedings. The mediator may be
chosen from a list of mediators previously selected by the parties or by other
agreement of the parties.  Costs of the mediation shall

                                       20
<PAGE>

be borne equally by the parties involved in the matter, except that each party
shall be responsible for its own expenses. Mediation is not a prerequisite to a
demand for arbitration under Section 8.3.

     8.3.  DEMAND FOR ARBITRATION.  (a) At any time after the first to occur of
(i) the date of the meeting actually held pursuant to the applicable Escalation
Notice or (ii) 45 days after the delivery of an Escalation Notice (as
applicable, the "Arbitration Demand Date"), any party involved in the dispute,
controversy or claim (regardless of whether such party delivered the Escalation
Notice) may, unless the Applicable Deadline has occurred, make a written demand
(the "Arbitration Demand Notice") that the dispute be resolved by binding
arbitration, which Arbitration Demand Notice shall be given to the parties to
the dispute, controversy or claim in the manner set forth in Section 10.5. In
the event that any party shall deliver an Arbitration Demand Notice to another
party, such other party may itself deliver an Arbitration Demand Notice to such
first party with respect to any related dispute, controversy or claim with
respect to which the Applicable Deadline has not passed without the requirement
of delivering an Escalation Notice. No party may assert that the failure to
resolve any matter during any discussions or negotiations, the course of conduct
during the discussions or negotiations or the failure to agree on a mutually
acceptable time, agenda, location or procedures for the meeting, in each case,
as contemplated by Section 8.2, is a prerequisite to a demand for arbitration
under Section 8.3.

     (b) Except as may be expressly provided in any Ancillary Agreement, any
Arbitration Demand Notice may be given until one year and 45 days after the
later of the occurrence of the act or event giving rise to the underlying claim
or the date on which such act or event was, or should have been, in the exercise
of reasonable due diligence, discovered by the party asserting the claim (as
applicable and as it may in a particular case be specifically extended by the
parties in writing, the "Applicable Deadline"). Any discussions, negotiations or
mediations between the parties pursuant to this Agreement or otherwise will not
toll the Applicable Deadline unless expressly agreed in writing by the parties.
Each of the parties agrees on behalf of itself and each member of its Group that
if an Arbitration Demand Notice with respect to a dispute, controversy or claim
is not given prior to the expiration of the Applicable Deadline, as between or
among the parties and the members of their Groups, such dispute, controversy or
claim will be barred. Subject to Sections 8.7(b) and 8.8, upon delivery of an
Arbitration Demand Notice pursuant to Section 8.3(a) prior to the Applicable
Deadline, the dispute, controversy or claim shall be decided by a sole
arbitrator in accordance with the rules set forth in this Article VIII.

     8.4.  ARBITRATORS.  (a) Within 15 days after a valid Arbitration Demand
Notice is given, the parties involved in the dispute, controversy or claim
referenced therein shall attempt to select a sole arbitrator satisfactory to all
such parties.

     (b) In the event that such parties are not able jointly to select a sole
arbitrator within such 15-day period, such parties shall each appoint an
arbitrator within 30 days after delivery of the Arbitration Demand Notice. If
one party appoints an arbitrator within such time period and the other party or
parties fail to appoint an arbitrator within such time period, the arbitrator
appointed by the one party shall be the sole arbitrator of the

                                       21
<PAGE>

matter.

     (c) In the event that a sole arbitrator is not selected pursuant to
paragraph (a) or (b) above and, instead, two or more arbitrators are selected
pursuant to paragraph (b) above, the two or more arbitrators will, within 30
days after the appointment of the later of them to be appointed, select an
additional arbitrator who shall act as the sole arbitrator of the dispute. After
selection of such sole arbitrator, the initial arbitrators shall have no further
role with respect to the dispute. In the event that the arbitrators so appointed
do not, within 30 days after the appointment of the later of them to be
appointed, agree on the selection of the sole arbitrator, any party involved in
such dispute may apply to CPR, New York, New York to select the sole arbitrator,
which selection shall be made by such organization within 30 days after such
application. Any arbitrator selected pursuant to this paragraph (c) shall be
disinterested with respect to any of the parties and the matter and shall be
reasonably competent in the applicable subject matter.

     (d) The sole arbitrator selected pursuant to paragraph (a), (b) or (c)
above will set a time for the hearing of the matter which will commence no later
than 90 days after the date of appointment of the sole arbitrator pursuant to
paragraph (a), (b) or (c) above and which hearing will be no longer than 30 days
(unless in the judgment of the arbitrator the matter is unusually complex and
sophisticated and thereby requires a longer time, in which event such hearing
shall be no longer than 90 days). The final decision of such arbitrator will be
rendered in writing to the parties not later than 60 days after the last hearing
date, unless otherwise agreed by the parties in writing.

     (e) The place of any arbitration hereunder will be New York, New York,
unless otherwise agreed by the parties.

     8.5.  HEARINGS.  Within the time period specified in Section 8.4(d), the
matter shall be presented to the arbitrator at a hearing by means of written
submissions of memoranda and verified witness statements, filed simultaneously,
and responses, if necessary in the judgment of the arbitrator or both the
parties. If the arbitrator deems it to be essential to a fair resolution of the
dispute, live cross-examination or direct examination may be permitted, but is
not generally contemplated to be necessary. The arbitrator shall actively manage
the arbitration with a view to achieving a just, speedy and cost-effective
resolution of the dispute, claim or controversy. The arbitrator may, in his or
her discretion, set time and other limits on the presentation of each party's
case, its memoranda or other submissions, and refuse to receive any proffered
evidence, which the arbitrator, in his or her discretion, finds to be
cumulative, unnecessary, irrelevant or of low probative nature. Except as
otherwise set forth herein, any arbitration hereunder will be conducted in
accordance with the CPR Rules for Non-Administered Arbitration of Business
Disputes then prevailing (except that the arbitration will not be conducted
under the auspices of the CPR and the fee schedule of the CPR will not apply).
Except as expressly set forth in Section 8.8(b), the decision of the arbitrator
will be final and binding on the parties, and judgment thereon may be had and
will be enforceable in any court having jurisdiction over the parties.
Arbitration awards will bear interest at an annual rate of the Prime Rate plus
2% per annum. To the extent that the provisions of this Agreement and the
prevailing rules of the CPR conflict, the provisions of this Agreement

                                       22
<PAGE>

shall govern.

     8.6.  DISCOVERY AND CERTAIN OTHER MATTERS.  (a) Any party involved in the
applicable dispute may request limited document production from the other party
or parties of specific and expressly relevant documents, with the reasonable
expenses of the producing party incurred in such production paid by the
requesting party. Any such discovery (which rights to documents shall be
substantially less than document discovery rights prevailing under the Federal
Rules of Civil Procedure) shall be conducted expeditiously and shall not cause
the hearing provided for in Section 8.5 to be adjourned except upon consent of
all parties involved in the applicable dispute or upon an extraordinary showing
of cause demonstrating that such adjournment is necessary to permit discovery
essential to a party to the proceeding. Depositions, interrogatories or other
forms of discovery (other than the document production set forth above) shall
not occur except by consent of the parties involved in the applicable dispute.
Disputes concerning the scope of document production and enforcement of the
document production requests will be determined by written agreement of the
parties involved in the applicable dispute or, failing such agreement, will be
referred to the arbitrator for resolution. All discovery requests will be
subject to the proprietary rights and rights of privilege of the parties, and
the arbitrator will adopt procedures to protect such rights and to maintain the
confidential treatment of the arbitration proceedings (except as may be required
by law). Subject to the foregoing, the arbitrator shall have the power to issue
subpoenas to compel the production of documents relevant to the dispute,
controversy or claim.

     (b) The arbitrator shall have full power and authority to determine issues
of arbitrability but shall otherwise be limited to interpreting or construing
the applicable provisions of this Agreement or any Ancillary Agreement, and will
have no authority or power to limit, expand, alter, amend, modify, revoke or
suspend any condition or provision of this Agreement or any Ancillary Agreement;
it being understood, however, that the arbitrator will have full authority to
implement the provisions of this Agreement or any Ancillary Agreement, and to
fashion appropriate remedies for breaches of this Agreement (including interim
or permanent injunctive relief); provided that the arbitrator shall not have (i)
any authority in excess of the authority a court having jurisdiction over the
parties and the controversy or dispute would have absent these arbitration
provisions or (ii) any right or power to award punitive or treble damages. It is
the intention of the parties that in rendering a decision the arbitrator give
effect to the applicable provisions of this Agreement and the Ancillary
Agreements and follow applicable law (it being understood and agreed that this
sentence shall not give rise to a right of judicial review of the arbitrator's
award).

     (c) If a party fails or refuses to appear at and participate in an
arbitration hearing after due notice, the arbitrator may hear and determine the
controversy upon evidence produced by the appearing party.

     (d) Arbitration costs will be borne equally by each party involved in the
matter, except that each party will be responsible for its own attorney's fees
and other costs and expenses, including the costs of witnesses selected by such
party.

                                       23
<PAGE>

     8.7.  CERTAIN ADDITIONAL MATTERS.  (a) Any arbitration award shall be a
bare award limited to a holding for or against a party and shall be without
findings as to facts, issues or conclusions of law (including with respect to
any matters relating to the validity or infringement of patents or patent
applications) and shall be without a statement of the reasoning on which the
award rests, but must be in adequate form so that a judgment of a court may be
entered thereupon. Judgment upon any arbitration award hereunder may be entered
in any court having jurisdiction thereof.

     (b) Prior to the time at which an arbitrator is appointed pursuant to
Section 8.4, any party may seek one or more temporary restraining orders or
preliminary injunctions in a court of competent jurisdiction if necessary in
order to preserve and protect the status quo. Neither the request for, or grant
or denial of, any such temporary restraining order or preliminary injunction
shall be deemed a waiver of the obligation to arbitrate as set forth herein and
the arbitrator may dissolve, continue or modify any such order. Any such
temporary restraining order or preliminary injunction shall remain in effect
until the first to occur of the expiration of the order in accordance with its
terms or the dissolution thereof by the arbitrator.

     (c) Except as required by law, the parties shall hold, and shall cause
their respective officers, directors, employees, agents and other
representatives to hold, the existence, content and result of mediation or
arbitration in confidence in accordance with the provisions of Article VIII and
except as may be required in order to enforce any award. Each of the parties
shall request that any mediator or arbitrator comply with such confidentiality
requirement.

     (d) In the event that at any time the sole arbitrator shall fail to serve
as an arbitrator for any reason, the parties shall select a new arbitrator who
shall be disinterested as to the parties and the matter in accordance with the
procedures set forth herein for the selection of the initial arbitrator. The
extent, if any, to which testimony previously given shall be repeated or as to
which the replacement arbitrator elects to rely on the stenographic record (if
there is one) of such testimony shall be determined by the replacement
arbitrator.

     8.8.  LIMITED COURT ACTIONS.  (a) Notwithstanding anything herein to the
contrary, in the event that any party reasonably determines the amount in
controversy in any dispute, controversy or claim (or any series of related
disputes, controversies or claims) under this Agreement or any Ancillary
Agreement is, or is reasonably likely to be, in excess of $5 million and if such
party desires to commence an Action in lieu of complying with the arbitration
provisions of this Article, such party shall so state in its Arbitration Demand
Notice. If the other parties to the arbitration do not agree that the amount in
controversy in such dispute, controversy or claim (or such series of related
disputes, controversies or claims) is, or is reasonably likely to be, in excess
of $5 million, the arbitrator selected pursuant to Section 8.4 hereof shall
decide whether the amount in controversy in such dispute, controversy or claim
(or such series of related disputes, controversies or claims) is, or is
reasonably likely to be, in excess of $5 million. The arbitrator shall set a
date that is no later than ten days after the date of his or her appointment for
submissions by the parties with respect to such issue. There shall not be

                                       24
<PAGE>

any discovery in connection with such issue. The arbitrator shall render his or
her decision on such issue within five days of such date so set by the
arbitrator. In the event that the arbitrator determines that the amount in
controversy in such dispute, controversy or claim (or such series of related
disputes, controversies or claims) is or is reasonably likely to be in excess of
$5 million, the provisions of Sections 8.4(d) and (e), 8.5, 8.6, 8.7 and 8.10
hereof shall not apply and on or before (but, except as expressly set forth in
Section 8.8(b), not after) the tenth business day after the date of such
decision, any party to the arbitration may elect, in lieu of arbitration, to
commence an Action with respect to such dispute, controversy or claim (or such
series of related disputes, controversies or claims) in any court of competent
jurisdiction. If the arbitrator does not so determine, the provisions of this
Article (including with respect to time periods) shall apply as if no
determinations were sought or made pursuant to this Section 8.8(a).

     (b) In the event that an arbitration award in excess of $5 million is
issued in any arbitration proceeding commenced hereunder, any party may, within
60 days after the date of such award, submit the dispute, controversy or claim
(or series of related disputes, controversies or claims) giving rise thereto to
a court of competent jurisdiction, regardless of whether such party or any other
party sought to commence an Action in lieu of proceeding with arbitration in
accordance with Section 8.8(a). In such event, the applicable court may elect to
rely on the record developed in the arbitration or, if it determines that it
would be advisable in connection with the matter, allow the parties to seek
additional discovery or to present additional evidence. Each party shall be
entitled to present arguments to the court with respect to whether any such
additional discovery or evidence shall be permitted and with respect to all
other matters relating to the applicable dispute, controversy or claim (or
series of related disputes, controversies or claims).

     8.9.  CONTINUITY OF SERVICE AND PERFORMANCE.  Unless otherwise agreed in
writing, the parties will continue to provide service and honor all other
commitments under this Agreement and each Ancillary Agreement during the course
of dispute resolution pursuant to the provisions of this Article VIII with
respect to all matters not subject to such dispute, controversy or claim.

     8.10. LAW GOVERNING ARBITRATION PROCEDURES.  The interpretation of the
provisions of this Article VIII, only insofar as they relate to the agreement to
arbitrate and any procedures pursuant thereto, shall be governed by the
Arbitration Act and other applicable federal law. In all other respects, the
interpretation of this Agreement shall be governed as set forth in Section 10.2.


                                   ARTICLE IX
                  FURTHER ASSURANCES AND ADDITIONAL COVENANTS

     9.1.  FURTHER ASSURANCES. (a) In addition to the actions specifically
provided for elsewhere in this Agreement, each of the parties hereto shall use
its reasonable best effort to take, or cause to be taken, all actions, and to
do, or cause to be done, all things reasonably necessary, proper or advisable
under applicable laws, regulations and agreements to consummate and make
effective the transactions

                                       25
<PAGE>

contemplated by this Agreement, the Ancillary Agreements and the Tax Agreement.

     (b) Without limiting the foregoing, each party hereto shall cooperate with
the other parties, and without any further consideration, but at the expense of
the requesting party, to execute and deliver, or use its reasonable best efforts
to cause to be executed and delivered, all instruments, including instruments of
conveyance, assignment and transfer, and to make all filings with, and to obtain
all consents, approvals or authorizations of, any Governmental Authority or any
other Person under any permit, license, agreement, indenture or other instrument
and to take all such other actions as such party may reasonably be requested to
take by any other party hereto from time to time, consistent with the terms of
this Agreement and the Ancillary Agreements, in order to effectuate the
provisions and purposes of this Agreement and the Ancillary Agreements and the
other transactions contemplated hereby and thereby. Without limiting the
foregoing, to the extent necessary to effectuate the provisions and purposes of
this Agreement and the Ancillary Agreements and the other transactions
contemplated hereby and thereby each party will, at the reasonable request, cost
and expense of any other party, take such other actions as may be reasonably
necessary to vest in such other party good and marketable title, free and clear
of any Security Interest, if and to the extent it is practicable to do so.

     (c) IDT and Net2Phone, and each of the members of their respective Groups,
waive (and agree not to assert against any of the others) any claim or demand
that any of them may have against any of the others for any Liabilities or other
claims relating to or arising out of: (i) the failure of Net2Phone or any member
of the Net2Phone Group, on the one hand, or of IDT or any member of the IDT
Group, on the other hand, to provide any notification or disclosure required
under any state Environmental Law in connection with the transactions
contemplated by this Agreement, or (ii) any inadequate, incorrect or incomplete
notification or disclosure under any such state Environmental Law by the
applicable transferor.

     (d) Following the date hereof, if one or more of the parties identifies any
commercial or other service that is needed to assure a smooth and orderly
transition of the businesses in connection with the consummation of the
transactions contemplated hereby, and that is not otherwise governed by the
provisions of this Agreement or any Ancillary Agreement, the parties will
cooperate in determining whether there is a mutually acceptable arm's-length
basis on which one or more of the other parties will provide such service.



                                   ARTICLE X
                                 MISCELLANEOUS

     10.1.  COUNTERPARTS; ENTIRE AGREEMENT; CORPORATE POWER.   
     (a)    This Agreement may be executed in one or more counterparts, all of
which shall be considered one and the same agreement, and shall become effective
when one or more counterparts have been signed by each of the parties and
delivered to the other party.

                                       26
<PAGE>

     (b) This Agreement, and the Exhibits, Schedules and Appendices hereto,
contain the entire agreement between the parties with respect to the subject
matter hereof, supersede all previous agreements, negotiations, discussions,
writings, understandings, commitments and conversations with respect to such
subject matter and there are no agreements or understandings between the parties
other than those set forth or referred to herein or therein.

     (c) IDT represents on behalf of itself and each other member of the IDT
Group and Net2Phone represents on behalf of itself and each other member of the
Net2Phone Group as follows:

       (i) each such Person has the requisite corporate or other power and
authority and has taken all corporate or other action necessary in order to
execute, deliver and perform each of this Agreement, each of the Ancillary
Agreements and the Tax Agreement to which it is a party and to consummate the
transactions contemplated hereby and thereby; and

       (ii) this Agreement, each Ancillary Agreement and the Tax Agreement to
which it is a party has been duly executed and delivered by it and constitutes a
valid and binding agreement of it enforceable in accordance with the terms
thereof subject to (a) the laws of bankruptcy and laws effecting creditors'
rights generally and (b) the availability of equitable remedies.

     10.2.  GOVERNING LAW.  Except as set forth in Section 8.10, this Agreement
shall be governed by and construed and interpreted in accordance with the laws
of the State of New York (other than as to its laws of arbitration which shall
be governed under the Arbitration Act or other applicable federal law pursuant
to Section 8.10), irrespective of the choice of laws principles of the State of
New York, as to all matters, including matters of validity, construction,
effect, enforceability, performance and remedies.

     10.3.  ASSIGNABILITY.  Except as set forth in any Ancillary Agreement or
the Tax Agreement, this Agreement (including without limitation the provisions
of Section 6.3 hereof), each Ancillary Agreement and the Tax Agreement shall be
binding upon and inure to the benefit of the parties hereto and thereto,
respectively, and their respective successors and assigns (whether by merger,
operation of law or otherwise); provided, however, that no party hereto or
thereto may assign its respective rights or delegate its respective obligations
under this Agreement, any Ancillary Agreement or the Tax Agreement without the
express prior written consent of the other parties hereto or thereto.

     10.4.  THIRD PARTY BENEFICIARIES.  Except for the indemnification rights
under this Agreement of any IDT Indemnitee or Net2Phone Indemnitee in their
respective capacities as such, (a) the provisions of this Agreement, each
Ancillary Agreement and the Tax Agreement are solely for the benefit of the
parties and are not intended to confer upon any Person except the parties any
rights or remedies hereunder, and (b) there are no third party beneficiaries of
this Agreement, any Ancillary Agreement or the Tax Agreement and none of this
Agreement, any Ancillary Agreement or the Tax Agreement shall provide any third
person with any remedy, claim, liability,

                                       27
<PAGE>

reimbursement, claim of action or other right in excess of those existing
without reference to this Agreement, any Ancillary Agreement or the Tax
Agreement. No party hereto shall have any right, remedy or claim with respect to
any provision of this Agreement, any Ancillary Agreement or the Tax Agreement to
the extent such provision relates solely to the other two parties hereto or the
members of such other two parties' respective Groups.

     10.5.  NOTICES.  All notices requests, demands, waivers and other
communications under this Agreement, any Ancillary Agreement or the Tax
Agreement shall be in writing and shall be deemed to have been duly given if
delivered personally or by facsimile transmission or mailed (certified or

or to such other person or address as any party shall specify by notice in
writing to the other party.  All such notices, requests, demands, waivers and
communications shall be deemed to have been received on the date on which hand
delivered, upon transmission of the facsimile transmission by the sender and
issuance by the transmitting machine of a confirmation slip confirming that the
number of pages constituting the notice have been transmitted without error, or
on the third business day following the date on which so mailed, except for a
notice of change of address, which shall be effective only upon receipt thereof.
In the case of a notice sent by facsimile transmission, the sender shall
contemporaneously mail a copy of the notice to the addressee at the address
provided for above.  However, such mailing shall in no way alter the time at
which the facsimile notice is deemed received.  In no event shall the provision
of notice pursuant to this Section 10.5 constitute notice for service of
process.

     10.6.  SEVERABILITY.  If any provision of this Agreement, any Ancillary
Agreement or the Tax Agreement or the application thereof to any Person or
circumstance is determined by a court of competent jurisdiction to be invalid,
void or unenforceable, the remaining provisions hereof or thereof, or the
application of such provision to Persons or circumstances or in jurisdictions
other than those as to which it has been held invalid or unenforceable, shall
remain in full force and effect and shall in no way be affected, impaired or
invalidated thereby, so long as the economic or legal substance of the
transactions contemplated hereby or thereby, as the case may be, is not affected
in any manner adverse to any party. Upon such determination, the parties shall

                                       28
<PAGE>

negotiate in good faith in an effort to agree upon such a suitable and equitable
provision to effect the original intent of the parties.

     10.7.  FORCE MAJEURE.  No party shall be deemed in default of this
Agreement, any Ancillary Agreement or the Tax Agreement to the extent that any
delay or failure in the performance of its obligations under this Agreement, any
Ancillary Agreement or the Tax Agreement results from any cause beyond its
reasonable control and without its fault or negligence, such as acts of God,
acts of civil or military authority, embargoes, epidemics, war, riots,
insurrections, fires, explosions, earthquakes, floods, unusually severe weather
conditions, labor problems or unavailability of parts, or, in the case of
computer systems, any failure in electrical or air conditioning equipment. In
the event of any such excused delay, the time for performance shall be extended
for a period equal to the time lost by reason of the delay.

     10.8.  PUBLICITY.  Each of Net2Phone and IDT shall consult with each other
prior to issuing any press releases or otherwise making public statements with
respect to the other transactions contemplated hereby and prior to making any
filings with any Governmental Authority with respect thereto.

     10.9.  HEADINGS.  The article, section and paragraph headings contained in
this Agreement and in the Ancillary Agreements and the Tax Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement, any Ancillary Agreement or the Tax Agreement.

     10.10.  SURVIVAL OF COVENANTS.  Except as expressly set forth in any
Ancillary Agreement and the Tax Agreement, the covenants, representations and
warranties contained in this Agreement, each Ancillary Agreement and the Tax
Agreement, and liability for the breach of any obligations contained herein,
shall survive the delivery hereof.

     10.11.  WAIVERS OF DEFAULT.  Waiver by any party of any default by the
other party of any provision of this Agreement, any Ancillary Agreement or the
Tax Agreement shall not be deemed a waiver by the waiving party of any
subsequent or other default, nor shall it prejudice the rights of the other
party.

     10.12.  SPECIFIC PERFORMANCE.  In the event of any actual or threatened
default in, or breach of, any of the terms, conditions and provisions of this
Agreement, any Ancillary Agreement or the Tax Agreement, the party or parties
who are or are to be thereby aggrieved shall have the right to specific
performance and injunctive or other equitable relief of its rights under this
Agreement, such Ancillary Agreement or the Tax Agreement, in addition to any and
all other rights and remedies at law or in equity, and all such rights and
remedies shall be cumulative. The parties agree that the remedies at law for any
breach or threatened breach, including monetary damages, are inadequate
compensation for any loss and that any defense in any action for specific
performance that a remedy at law would be adequate is waived. Any requirements
for the securing or posting of any bond with such remedy are waived.

whom it is sought to enforce such waiver, amendment, supplement or modification.
