NOW THEREFORE, with the intent to be legally bound hereby, and in consideration of the mutual promises and covenants contained herein and other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, IDT and EMPLOYEE agree to the terms and conditions set forth below.

1. Payment.

1.1. EMPLOYEE shall be entitled to the following payments from IDT, all of which shall be wired to EMPLOYEE’S bank account, the details of which are on file with IDT’s employee direct deposit program:

(a) EMPLOYEE shall receive compensation based on an annual salary of Six Hundred Thousand Dollars ($600,000) (the “Base Salary”) from and after April 1, 2008 through the Termination Date (the “Transition Period”). Such Base Salary shall be paid less applicable taxes and customary withholding, such salary to be paid in conformity with the Company’s payroll policies relating to its employees. Any base salary earned through the Termination Date but unpaid at such time shall be paid at such time as other IDT employees are paid for such period.

(c) IDT agrees to pay EMPLOYEE One Million Nine Hundred Ninety Nine Thousand Seven Hundred Six Dollars and One Cent ($1,999,706.01) (the “Severance Pay”), to be paid in accordance with the payment schedule outlined in Exhibit A (the “Severance Pay Period”), the completion of such schedule subject to IDT’s receipt from EMPLOYEE of an affirmation of the general release contained in Section 9 in the form of Exhibit B hereto, as indicated on Exhibit A. The first payment will be paid immediately upon the expiration of the Revocation Period (as hereafter defined).

1.2. EMPLOYEE shall receive reimbursement by IDT for all reasonable and approved business expenses incurred prior to the Termination Date in accordance with IDT’s policies.

1.3. All payments hereunder shall be less required withholdings for taxes and benefit plan contributions (if any).

2. Benefits.

2.1. As of the Termination Date, EMPLOYEE shall be eligible to elect the continuance of group health and dental insurance (if EMPLOYEE is currently enrolled in the IDT sponsored plan), in accordance with federal COBRA law.

2.2. If EMPLOYEE so elects, and so long as EMPLOYEE is entitled to COBRA coverage, during the Severance Pay Period, EMPLOYEE’s premiums for group health and dental insurance under COBRA shall be the same amount that an active employee contributes for such benefit coverage. If EMPLOYEE wishes to elect COBRA (continue coverage in the then current group medical and/or dental plan after June 30, 2008), EMPLOYEE must complete and sign the COBRA Election Form and return it to Human Resources in accordance with COBRA. After the Severance Pay Period, EMPLOYEE’s premiums for COBRA coverage will be the published rate of group health insurance under COBRA.

2.3. After the Termination Date, EMPLOYEE will not continue to accrue vacation benefits or commissions, or otherwise be eligible for Life or Disability benefits, or continue to contribute to the IDT Savings Plan or 401(k) Plan, or participate in the Employee Stock Purchase Plan, and will not receive any other benefits from IDT, other than those specified in this Agreement. EMPLOYEE’s rights with respect to any options to purchase IDT stock or IDT stock he may have received from IDT are governed by the applicable award agreements and plan documents.

3. Payment of all Outstanding Compensation. Except for those obligations specifically set forth in this Agreement, as of the Termination Date, any and all agreements or arrangements, either oral or written, between the Parties related to commissions, bonuses, ownership or other interests in any entities or assets, payments

and/or compensation of any kind, including but not limited to any documents, correspondence, oral promises and any other arrangements related to the proposal known as the Jonah Value Creation Project, (“Compensation”) are deemed null and void without any continuing obligation or liability of any party thereunder; it being understood that, among other things, from and after the Termination Date, except as expressly provided hereunder, IDT will have no obligation to pay EMPLOYEE any Compensation or have any duties, responsibilities or other obligations to EMPLOYEE with respect to any agreement or arrangement and EMPLOYEE will have no rights thereunder. EMPLOYEE acknowledges and agrees that he is due no other compensation, commission payments, benefits or other consideration of any kind other than as specifically identified in this Agreement.

4. Equipment. Unless otherwise expressly provided in Exhibit C, EMPLOYEE will return any and all IDT property and equipment in his possession, including, but not limited to, any and all IDT identification cards, card key passes, keys, pagers, computers (office desktop), cellular telephones or similar personal digital assistant devices, corporate credit cards, corporate calling cards, and any other property or equipment in his possession that IDT may not know of, on or before the Termination Date.

5. Termination of Employment; Resignation. EMPLOYEE acknowledges and agrees that his employment by IDT will terminate on the Termination Date, and that he will be deemed to have resigned from all officer positions and directorships that he may hold with IDT (or otherwise at the request of IDT) upon execution of this Agreement, other than his position as General Counsel of IDT Telecom from which he shall resign at the end of the Transition Period (or upon the earlier request of the CEO of IDT Telecom). Contemporaneously herewith, EMPLOYEE shall execute and deliver a resignation letter from such officer positions and directorships in the form attached hereto as Exhibit D. EMPLOYEE acknowledges and agrees that he is due no other compensation, commission payments, benefits or other compensation of any kind other than as specifically identified in this Agreement.

IDT shall attempt, in good faith and when possible, to issue the above referenced requests so as not to prevent EMPLOYEE’s efficient disposition of same, and EMPLOYEE agrees to comply in good faith with IDT’s requests.

10. No Admission of Liability. The making of this Agreement and anything contained herein is not intended, and shall not be construed, as an admission that IDT has violated any foreign, federal, state or local law (statutory or common law), ordinance or regulation; breached any contract; or violated any right or obligation that it may owe or may have owed to EMPLOYEE, or committed any wrong whatsoever against EMPLOYEE. EMPLOYEE further acknowledges, covenants, and agrees that no final findings or final judgments have been made by any court or arbitration panel against IDT in favor of EMPLOYEE, and that EMPLOYEE does not purport and will not claim to be a prevailing party, for any purpose.

11. Confidentiality of Agreement. The Parties agree that the consideration furnished under this Agreement, the discussions and correspondence that led to this Agreement, and the terms and conditions of this Agreement are confidential. EMPLOYEE represents that he, and any attorney he may have retained to review this Agreement, have not disclosed the terms or conditions of this Agreement. Except as may be required by law or to enforce the terms hereof, neither EMPLOYEE nor his attorney may disclose the above information to any other person or entity, except that EMPLOYEE may disclose the provisions of this Agreement to his immediate family members and financial and/or tax advisor, provided that EMPLOYEE makes the person to whom disclosure is made aware of the confidentiality provisions of this Agreement and such person agrees in writing to keep confidential the terms of this Agreement. If subpoenaed to appear in any civil or criminal litigation, or by any governmental authority, to testify as to the contents of this Agreement, EMPLOYEE agrees to immediately forward a copy of the subpoena to the Chief Legal Officer of IDT so that IDT may contest such subpoena, or any request, requirement or order related thereto, and to notify the proponent of the subpoena that this Agreement is the subject of an agreement of confidentiality.

IDT owns all right, title and interest in and to the Confidential Information and other intellectual property owned by IDT, including, without limitation, the IDT Inventions. EMPLOYEE agrees that he acquired no right, title or interest in any Confidential Information or the IDT Inventions; and the Confidential Information is specialized, unique in nature, and of great value to IDT and that such Confidential Information gives IDT a competitive advantage. EMPLOYEE hereby agrees to promptly return to IDT all tangible materials and all copies thereof, in whatever media, in his possession or control, containing or employing any Confidential Information or the IDT Inventions, together with a written certification with the foregoing.

12.3.

Each Party further agrees that he will not engage in any conduct that is in any way injurious, or may be perceived to be injurious, to the other Party’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 such other Party.

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 Section 1.1(c) of this Agreement.

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.
