As of April 1, 2008

Dear Marcelo:

You have been a member of the management team of IDT for many years, serving in a variety of capacities, including Chief Accounting Officer and Controller of IDT Corporation, Chief Financial Officer of IDT Corporation and Chief Financial
Officer of IDT Telecom. This letter (the Agreement) sets forth the terms in the event of your termination of employment with IDT Corporation and IDT Telecom (collectively the Company).

If:



| | (i) | the Company terminates your employment for any reason other than Cause during the two (2) year period following the date of this Agreement;
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | you terminate your employment for any reason during any Termination Option Period (as defined below); or
| | ---- | --------------------------------------------------------------------------------------------------------



| | (iii) | you die or become incapacitated during the two (2) year period following the date of this Agreement,
| | ----- | ----------------------------------------------------------------------------------------------------

you shall be entitled to receive severance in the aggregate amount of One Million One Hundred Seventy Thousand Dollars ($1,170,000), (the
Severance), provided you execute and deliver a separation agreement and general release of claims against the Company (substantially similar to the Company standard form annexed hereto as Exhibit 1, the Release) within one
(1) month after the date of such termination of employment. The Company shall promptly commence the severance payments following receipt of the Release and upon expiration of the Revocation Period (defined in attached Release). As used herein,
the term Termination Option Period shall mean any time during the months of August 2008, November 2008 or February 2009, or any time between April 1, 2009 and March 31, 2010.



---

The Severance will be paid in the following manner:



| | (i) | IDT shall promptly pay Eight Hundred Thirty-Five Thousand Dollars ($835,000.00) upon execution and delivery of the Release and expiration of the Revocation Period.
| | --- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | One Hundred Sixty-Seven Thousand Five Hundred Dollars ($167,500.00) on or before 90 days after the date of termination (Second Payment Period) provided execution and
delivery of the above mentioned Release.

| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Notwithstanding the above, if the Compensation Committee of the Company determines that you are a specified employee within the
meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the Code) and that such amounts are not exempt from Code Section 409A, then any Severance to be paid pursuant to this Agreement will not be paid during
the six month period following your termination of employment. Instead, the Company will pay you, in a lump sum amount, on the first day following such six month period, the full Severance.

Except for those obligations specifically set forth in this Agreement, as of the date of this Agreement, any and all agreements or arrangements, either
oral or written, between the Company and you, related to severance, commissions, bonuses or compensation of any nature, including, without limitation, any documents, correspondence, oral promises or any other arrangements related to the proposal
known as the Jonah Value Creation Project are null and void.

If you are at any time terminated for Cause or you terminate your employment
with the Company other than during a Termination Option Period, you shall forfeit any entitlement to the Severance. For purposes of entitlement to the Severance, Cause shall be defined as your:



| | (i) | conviction for the commission of an act or acts constituting a felony under the laws of the United States or any state thereof;
| | --- | -------------------------------------------------------------------------------------------------------------------------------



| | (ii) | commission of fraud, embezzlement, gross negligence or malfeasance;
| | ---- | -------------------------------------------------------------------



| | (iii) | willful or continued failure to substantially perform your duties (other than any such failure resulting from your incapacity due to physical or mental illness) or
directives of the Board, after written notice has been delivered to you by the Company, which notice specifically identifies the manner in which you have not substantially performed your duties, and your failure to substantially perform
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

| | your duties is not cured within ten (10) business days after notice of such failure has been given to you. For purposes of these Sections (iii),
(iv) and (vi), no act or failure to act on your part shall be deemed willful unless done or omitted to be done, by you not in good faith and without reasonable belief that your act, or failure to act, was in the best interest of the
Company;
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | willful misrepresentation or concealment of a material fact from the Board or general counsel, chief financial officer or any other member of senior
management;
| | ---- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) | material violation of the Companys rules, policies or procedures, including without limitation, the Companys Code of Business Conduct and Ethics; or
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------



| | (vi) | willful or negligent act or omission which results in an assessment of a civil or criminal penalty against you or the Company or its affiliates, which in the reasonable judgment of
the Board could result in a material violation of any foreign or United States federal, state or local law or regulation having the force of law, or in the reasonable judgment of the Board is injurious to the Company or any of its affiliates.
| | ---- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

You agree to provide the Company with 30 days written notice of the intention to terminate your employment with the Company.
The Company agrees to provide you with 30 day written notice of the intention to terminate your employment, if such termination is to be prior to March 31, 2009. In the event that you terminate your employment with the Company, the Company
shall be entitled to waive all or part of such notice period, and determine the effective date of termination accordingly.

The Company has
no obligation to rehire, recall or re-employ you at any time and nothing herein creates any right or entitlement to continued employment.

With the exception of the Companys Non-Disclosure and Non-Competition Agreement (NDA) and any stock option, restricted share or other incentive award agreements which may be issued by the Company, the explicit terms of
this letter supersede any and all prior agreements, arrangements, promises, covenants, communications, representations or warranties, whether oral or written, by any officer, employee or representative of the Company, or its parent or affiliates
(including, but not limited to any documents, correspondence, oral promises or any other arrangements related to the proposal known as the Jonah Value Creation Project); and any prior agreement in respect of the terms of your employment with or
severance from the Company, its parent or affiliates is hereby terminated and canceled.

14. Non-Disparagement. EMPLOYEE agrees that he will not at any time, in any way, disparage IDT
or any individuals associated with IDT, including its present or former officers, directors, agents and employees, by making or soliciting any comments, statements or the like to the media or to others, either orally or in writing, that may be
considered to be derogatory or detrimental, in any way, to the good name or business reputation of IDT or such other persons. EMPLOYEE further agrees that he will not engage in any conduct that is in any way injurious, or may be perceived to be
injurious, to IDTs reputation or interest (other than normal competitive process not in violation of this Agreement), including, but not limited to, encouraging or assisting others to bring any form of suit, claim or cause of action against
IDT.



---

15. Breach. EMPLOYEE agrees and acknowledges that if he breaches any representation, covenant,
promise or undertaking made pursuant to this Agreement, IDT is authorized to pursue all rights and remedies available in law or in equity, which rights and remedies may include, but are not limited to, EMPLOYEEs obligation to promptly return
to IDT all amounts paid by IDT to EMPLOYEE under this Agreement.

16. Agreement Not Admissible. The Parties agree that this
Agreement may be used and admitted as evidence only in a subsequent proceeding in which IDT or EMPLOYEE seeks to enforce its/his rights hereunder.

17. Representations and Warranties. EMPLOYEE represents and warrants that he has been advised in writing to consult with an attorney before signing this Agreement; that he has had an opportunity to be represented by independent legal
counsel of his own choice throughout all of the negotiations preceding the execution of this Agreement; that he has executed this Agreement after the opportunity for consultation with above-described independent legal counsel; that he is of sound
mind and body, competent to enter into this Agreement, and is fully capable of understanding the terms and conditions of this Agreement; that he has carefully read this Agreement in its entirety; that he has had the opportunity to have the
provisions of this Agreement explained to him by his own counsel, who has answered to his satisfaction any questions he has asked with regard to the meaning of any of the provisions of this Agreement, and that he fully understands their terms and
significance; and that he voluntarily assents to all the terms and conditions contained therein, and that he is signing this Agreement of his own force and will, without any coercion or duress. EMPLOYEE acknowledges and agrees that IDT has advised
that all payments to him must comply with the requirements of Section 409A of the Internal Revenue Code (409A) and EMPLOYEE agrees to indemnify and hold harmless IDT from and against any and all taxes, costs and expenses as a
result of any non-compliance with 409A.

18. Consideration and Revocation Periods. Pursuant to the Older Workers Benefit Protection
Act, EMPLOYEE is advised that he shall have at least 21 days to consider this Agreement before signing it, but may sign this Agreement at any earlier time if he so desires. If EMPLOYEE signs this Agreement, he shall have 7 calendar days thereafter
(the Revocation Period) to revoke this Agreement by indicating his desire to do so, in writing, addressed to IDT CorporationLegal Department, 520 Broad Street, 4th Floor, Newark, New Jersey 07102 (attention: General
Counsel). In order for such revocation to be effective, it must be received before 5:00 p.m. on the seventh day following the date this Agreement was executed by EMPLOYEE. The effective date of this Agreement shall be the 8th day following the
execution of this Agreement by EMPLOYEE (the Effective Date). In the event EMPLOYEE does not accept this Agreement, or in the event EMPLOYEE revokes this Agreement during the Revocation Period, this Agreement, including,
but not limited to, the obligation of IDT to make the payments set forth in Section 1, shall automatically be deemed null and void, and EMPLOYEE shall promptly return to IDT any amounts paid by IDT to EMPLOYEE under this Agreement.

19. Severability. If, at any time after the date EMPLOYEE executes this Agreement, any provision of this Agreement shall be held to be illegal,
void or unenforceable, such provision shall be of no force and effect, provided that, in the event that any provision of Section 13 is held invalid or unenforceable or is deemed to exceed the time, geographic or scope limitations
permitted by applicable law, then such



---

provisions shall be reformed to the maximum time, geographic or scope limitations, as the case may be, permitted by applicable laws, and such other changes
shall be made to give effect to the original intent of the Parties. The illegality or unenforceability of any provision shall have no effect upon, and shall not impair the enforceability of, any other provision of this Agreement, provided
that, upon a finding by a court or agency of competent jurisdiction that the release of claims contained in Section 9 is illegal, void or unenforceable, EMPLOYEE agrees that, at the request of IDT, he will execute a release covering all
the same claims as are released under Section 9 that are legal and enforceable, or, if the basis on which the release was found illegal, void or unenforceable cannot be so cured, to return promptly to IDT, upon its request, all amounts
