(b) Any registration under Section 2.4(a) shall be on such appropriate registration form of the SEC as shall permit the disposition of the Registrable Securities covered by such registration in accordance with the intended method or methods of disposition specified by Holders holding at least two-thirds (2/3) of the Registrable Securities; provided, however, that IDT may, if permitted by law, effect the registration required under Section 2.4(a) by the filing of a registration statement on Form S-3 under the Securities Act of 1933, as amended (the “Securities Act”); and provided, further, that no Holder shall be entitled to have the Registrable Securities held by it covered by such registration statement unless such Holder has provided IDT with the information required

under Section 2.4(j) hereof at least ten (10) business days before such Holder’s intended disposition of Registrable Securities and has agreed in writing to be bound by all of the provisions of this Agreement applicable to such Holder in accordance with Section 2.4(l) hereof. If Holders holding at least two-thirds (2/3) of the Registrable Securities notify IDT in writing that, in their reasonable judgment, the use of the more detailed form specified in such notice is of material importance to the success of such offering, IDT shall in good faith consider such request to effect such registration on the form so specified by such Holders, but shall be under no obligation to effect such registration on such form, and all expenses incurred in connection with effecting such registration on the form so specified by the Holders requesting the use of such form shall be borne by such Holders, jointly and severally.

(c) Subject to Section 2.4(e) below, a registration required pursuant to Section 2.4 shall not be deemed to have been effected (i) unless a registration statement with respect thereto has been declared effective by the SEC and remains effective in compliance with the provisions of the Securities Act until such time as all of the Registrable Securities covered thereby have been disposed of in accordance with such registration statement (the “Registration Period”) or (ii) if, after the registration statement with respect thereto has become effective, such registration is interfered with by any stop order, injunction or other order or requirement of the SEC or other governmental or regulatory agency or court for any reason other than a violation of applicable law by the Seller and has not thereafter become effective. IDT shall furnish to each Holder, promptly after such registration statement is filed with the SEC, such numbers of copies of the registration statement and any amendment or post-effective amendment thereto (in each case including all exhibits and the prospectus) and any other prospectus filed under Rule 424 under the Securities Act as such Holder may reasonably request.

(d) Subject to Section 2.4(e) below, IDT shall prepare and file such amendments (including post-effective amendments) and supplements to any registration statement filed under this Section 2.4 and the prospectus used in connection therewith as may be necessary to comply with the provisions of the Securities Act with respect to the sale or other disposition of all securities covered by such registration statement, or to name a Holder as a selling stockholder, until the earlier of such time as all of such securities have been disposed of in a public offering or the expiration of the Registration Period.

(e) Notwithstanding anything to the contrary herein, any registration effected pursuant to this Section 2.4 shall not be required to be effective on and after the first date on which the Holders can publicly sell all of the Registrable Securities pursuant to Rule 144(k) under the Securities Act.

(f) IDT shall promptly notify each Holder in the manner prescribed in Section 9.7 of the happening of any event, of which IDT has knowledge, as a result of

which the prospectus included in a registration statement effected pursuant to this Section 2.4, 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 not misleading, and shall promptly prepare a supplement or amendment to such registration statement to correct such untrue statement or omission, and deliver such number of copies of such supplement or amendment to each Holder as such Holder may reasonably require.

(g) IDT shall use commercially reasonable efforts to register or qualify the Registrable Securities under such state securities or “blue sky” laws of such jurisdictions as the Holders reasonably request and do any and all acts and things that may be reasonably necessary or advisable to enable the Holders to consummate the disposition of the Registrable Securities in such jurisdiction; provided, however, that IDT shall not be obligated to qualify as a foreign corporation to do business under the laws of any jurisdiction in which it is not then qualified or to file any consent to general service of process in any jurisdiction. IDT shall cause the listing and continuation of listing of the Registrable Securities on the New York Stock Exchange or, if the IDT Class B common stock is not listed on the New York State Exchange, such other principal exchange or automated quotation system on which the IDT Class B common stock trades.

(h) IDT shall enter into customary agreements (including an underwriting agreement in customary form) and take such other actions as are reasonably required in order to facilitate the disposition of such Registrable Securities.

(i) IDT shall otherwise use its best efforts to comply with all applicable rules and regulations of the SEC, and make available to each Holder, as soon as reasonably practicable, but not later than 18 months after the effective date of the registration statement, an earnings statement covering the period of at least 12 months beginning with the first full month after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 1l(a) of the Securities Act.

(j) Each Holder shall furnish IDT, from time to time, such information regarding itself, the Registrable Securities held by it, the intended method of disposition of the Registrable Securities held by it and all other information as is reasonably required by IDT to effect the registration of the resale of the Registrable Securities held by such Holder, all of which information shall be true, accurate, complete and not materially misleading.

(k) Subject to Section 2.4(b), all expenses incurred in connection with registrations, filings, qualifications and other obligations of IDT pursuant to this Section 2.4 shall be borne by IDT.

(l) The Seller shall have the right to transfer, subject to compliance with state and federal securities laws, all or a portion of the Registrable Securities to any Person receiving a distribution in connection with the bankruptcy case of the Seller and

its affiliates, provided that such transferee agrees in writing to be bound by all of the provisions of this Agreement applicable to such Holder and provides the other Parties with its contact information for notices pursuant to Section 9.7 hereof and the information required to be set forth on Schedule 3.1.

2.5 Indemnification and Contribution.

(a) In the event of any registration of any Registrable Securities under the Securities Act pursuant to this Agreement, IDT shall indemnify and hold harmless each Holder, such Holder’s respective directors and officers, and each other person (including each underwriter) who participated in the offering of such Registrable Securities and each other person, if any, who controls such Holder or such participating person within the meaning of the Securities Act, against any losses, claims, damages or liabilities, joint or several, to which such Holder or any such director or officer or participating person or controlling person may become subject under the Securities Act or any other statute or at common law, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any alleged untrue statement of any material fact contained, on the effective date thereof, in any registration statement under which such securities were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto, or (ii) any alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse such Holder or such director, officer or participating person or controlling person for any legal or any other expenses reasonably incurred by such Holder or such director, officer or participating person or controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that IDT shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any actual or alleged untrue statement or actual or alleged omission made in such registration statement, preliminary prospectus, prospectus or amendment or supplement in reliance upon and in conformity with written information furnished to IDT by a Holder specifically for use therein or so furnished for such purposes by any underwriter. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Holders or such director, officer or participating person or controlling person, and shall survive the transfer of such securities by the Holders.

(b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless IDT and each other Holder, their respective directors and officers and each other person, if any, who controls IDT or such other Holder within the meaning of the Securities Act against any losses, claims, damages or liabilities, joint or several, to which IDT or such other Holder or any such director or officer or any such person may become subject under the Securities Act or any other statute or at common law, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon information in writing provided to IDT by such Holder specifically for use in, and contained in, on the effective date thereof, any registration statement under which securities were registered under the Securities Act pursuant to this Agreement, any

preliminary prospectus or final prospectus contained therein, or any amendment or supplement thereto. Notwithstanding the provisions of this paragraph (b) or paragraph (c) below, no Holder shall be required to indemnify any person pursuant to this Section 2.5 or to contribute pursuant to paragraph (c) below in an amount in excess of the amount of the aggregate net proceeds received by such Holder in connection with any such registration under the Securities Act.

(c) If the indemnification provided for in this Section 2.5 from the indemnifying party is unavailable to an indemnified party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and indemnified parties in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified parties shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or indemnified parties, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with any investigation or proceeding.

The Parties agree that it would not be just and equitable if contribution pursuant to this Section 2.5(c) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation.

2.6 The Closing. The Closing shall take place at a location mutually acceptable to the Buyer and the Seller on the first Business Day following the date the conditions to Closing set forth in Article VII hereof are satisfied, or such other date as shall be mutually acceptable to the Buyer and the Seller (the “Closing Date”).
