(b) On the Closing Date (as defined in Section 2.04(a) below), each Seller Subsidiary shall file a certificate of merger with the Secretary of State of Delaware and make all other filings or recordings required by the DGCL in connection with the Merger to which it is a party. Each Merger shall become effective at such time (the “Effective Time”) as the corresponding certificate of merger is duly filed with the Secretary of State of Delaware or at such later time as is specified in such certificate of merger.

(c) From and after the Effective Time of each Merger, the Surviving Entity of such Merger shall possess all the rights, powers, privileges and franchises and be subject to all of the obligations, liabilities, restrictions and disabilities of the Seller Subsidiary party to such Merger and the IDT Subsidiary party to such Merger, all as provided under the DGCL, and thereafter neither LMC Animal Planet nor any of its Affiliates (as defined in Section 7.01 below) shall have any right, obligation or liability with respect to any Seller Subsidiary other than as expressly set forth in this Agreement.

Section 1.02 Conversion of Shares.

(a) At the Effective Time of the Merger of Liberty N2P and IDT Sub 1, by virtue of such Merger and without any action on the part of any of the parties hereto or any holder of any securities of Liberty N2P or IDT Sub 1, (i) each share of common stock of Liberty N2P outstanding immediately prior to such Effective Time shall automatically be converted into the right to receive 3,268.9719 shares of Class B Common Stock, par value $.01 per share, of IDT Parent (“IDT Parent Class B Common Stock”), and (ii) each share of common stock of IDT Sub 1 outstanding immediately prior to such Effective Time shall automatically be converted into one share of common stock of Surviving Entity 1.

(b) At the Effective Time of the Merger of Liberty N2P II and IDT Sub 2, by virtue of such Merger and without any action on the part of any of the parties hereto or

-2-

any holder of any securities of Liberty N2P II or IDT Sub 2, (i) each share of common stock of Liberty N2P II outstanding immediately prior to such Effective Time shall automatically be converted into the right to receive 236.3762 shares of IDT Parent Class B Common Stock, and (ii) each share of common stock of IDT Sub 2 outstanding immediately prior to such Effective Time shall automatically be converted into one share of common stock of Surviving Entity 2.

(c) At the Effective Time of the Merger of Liberty N2P III and IDT Sub 3, by virtue of such Merger and without any action on the part of any of the parties hereto or any holder of any securities of Liberty N2P III or IDT Sub 3, (i) each share of common stock of Liberty N2P III outstanding immediately prior to such Effective Time shall automatically be converted into the right to receive 249.1313 shares of IDT Parent Class B Common Stock, and (ii) each share of common stock of IDT Sub 3 outstanding immediately prior to such Effective Time shall automatically be converted into one share of common stock of Surviving Entity 3. The shares of IDT Parent Class B Common Stock issuable in the Mergers, as may be adjusted pursuant to Section 1.02(d), are referred to herein as the “Consideration Shares.”

(d) In the event of any dividend, distribution, recapitalization, stock split or combination, or similar event with respect to or affecting the IDT Parent Class B Common Stock after the date hereof and prior to the Effective Time of the Mergers, the foregoing exchange ratios shall be appropriately adjusted.

(e) At the Effective Time of each Merger, all shares of common stock of Liberty N2P, Liberty N2P II and Liberty N2P III, as applicable, that have been converted into the right to receive shares of IDT Parent Class B Common Stock shall be automatically canceled and shall cease to exist, and the holder of the common stock of Liberty N2P, Liberty N2P II and Liberty N2P III shall cease to have any rights with respect to such shares, other than the right to receive certificates representing the Consideration Shares exchangeable therefor.

Section 1.03 No Fractional Shares. No certificates or scrip representing fractional shares of IDT Parent Class B Common Stock shall be issued as a result of any conversion provided for in Section 1.02. In lieu of the issuance of fractional shares, in the event a holder of Seller Subsidiary capital stock would be entitled to receive any fraction of a share of IDT Parent Class B Common Stock pursuant to Section 1.02, such fraction shall be rounded up to the nearest whole number, so that such holder will receive a whole number of shares of IDT Parent Class B Common Stock; provided, however, that if more than one certificate representing shares of any Seller Subsidiary capital stock shall be surrendered for the account of the same holder, the number of shares of IDT Parent Class B Common Stock for which certificates have been surrendered shall be computed on the basis of the aggregate number of shares represented by the certificates so surrendered with respect to such Seller Subsidiary.

Section 1.04 Stock Transfer Books; Extinction of Stockholder Rights. At the Effective Time of each Merger, the stock transfer books of the Seller Subsidiary party to such Merger shall be closed with respect to the shares of common stock of such Seller

-3-

Subsidiary outstanding immediately prior to such Effective Time. All Consideration Shares issued upon surrender of a certificate representing shares of common stock of any Seller Subsidiary in accordance with the terms hereof shall be deemed to have been issued in full satisfaction of all rights pertaining to that certificate and the shares of Seller Subsidiary common stock represented thereby, and there shall be no further registration of transfers on the stock transfer books of any Seller Subsidiary of shares of common stock of such Seller Subsidiary outstanding immediately prior to the Effective Time of the Merger to which such Seller Subsidiary is party.

Section 1.05 Tax Effect. The parties intend that each of the Mergers shall qualify as a tax-free reorganization within the meaning of Section 368(a) of the Code and that this Agreement shall be and hereby is adopted by each of the parties as a plan of reorganization for purposes of Section 368 of the Code and the Treasury Regulations (as defined in Section 7.01 below) thereunder.

-27-

Entity or any other person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed (including but not limited to with respect to the transactions contemplated hereby).

Section 7.06 Tax Indemnification.

(a) LMC Animal Planet hereby indemnifies IDT Parent and its Affiliates (each a “Purchaser Indemnitee”) against and agrees to hold each Purchaser Indemnitee harmless from any (w) Tax of any of the Seller Subsidiaries described in clause (i) of the definition of Tax related to a Pre-Closing Tax Period, (x) Tax described in clause (ii) or (iii) of the definition of Tax, (y) Tax of any of the Seller Subsidiaries resulting from a breach of the provisions of Section 7.02, Section 7.03 or Section 7.04 and (z) liabilities, costs, expenses (including, without limitation, reasonable expenses of investigation and attorneys’ fees and expenses), losses, damages, assessments, settlements or judgments arising out of or incident to the imposition, assessment or assertion of any Tax described in clause (w), (x) or (y) above, (the sum of clauses (w), (x), (y) and (z) being referred to herein as a “Purchaser Loss”); provided, however, that LMC Animal Planet shall not have any indemnity obligation under this Section 7.06(a) in the event such Purchaser Loss results from a breach by IDT Parent or any of its Affiliates of any of the representations and warranties contained in Section 7.08(a) or the covenants contained in Section 7.08(b).

(b) For purposes of this Section 7.06, in the case of any Taxes that are imposed on a periodic basis and are payable for a Tax period that includes (but does not end on) the Closing Date, the portion of such Tax related to the portion of such Tax period ending on and including the Closing Date shall (x) in the case of any Taxes other than gross receipts, sales or use Taxes and Taxes based upon or related to income, be deemed to be the amount of such Tax for the entire Tax period multiplied by a fraction the numerator of which is the number of days in the Tax period ending on and including the Closing Date and the denominator of which is the number of days in the entire Tax period, and (y) in the case of any Tax based upon or related to income and any gross receipts, sales or use Tax, be deemed equal to the amount which would be payable if the relevant Tax period ended on and included the Closing Date. All determinations necessary to give effect to the allocation set forth in the foregoing clause (y) shall be made in a manner consistent with prior practice of LMC Animal Planet.

(c) Not later than 5 days after receipt by LMC Animal Planet of written notice from Purchaser Indemnitee stating that any Purchaser Loss has been incurred by a Purchaser Indemnitee and the amount thereof and of the indemnity payment requested, LMC Animal Planet shall discharge its obligation to indemnify the Purchaser Indemnitee against such Purchaser Loss by paying to Purchaser Indemnitee an amount equal to the amount of such Purchaser Loss. The payment by a Purchaser Indemnitee of any Purchaser Loss shall not relieve LMC Animal Planet of its obligations under this Section 7.06.

(d) Purchaser Indemnitee shall give prompt notice to LMC Animal Planet of any Purchaser Loss or the assertion of any claim, or the commencement of any suit,

-28-

action or proceeding in respect of which indemnity may be sought under this Section 7.06 which Purchaser Indemnitee deems to be within the ambit of this Section 7.06 (specifying with reasonable particularity the basis therefor) and will give LMC Animal Planet such information with respect thereto as LMC Animal Planet may reasonably request. LMC Animal Planet may, at its own expense, participate in and upon notice to Purchaser Indemnitee, assume the defense of any such suit, action or proceeding (including any Tax audit) in so far as it relates to the Purchaser Loss; provided that (x) counsel for LMC Animal Planet is reasonably satisfactory to Purchaser Indemnitee, (y) LMC Animal Planet shall thereafter consult with Purchaser Indemnitee upon Purchaser Indemnitee’s reasonable request for such consultation from time to time with respect to such suit, action or proceeding (including any Tax audit) and (z) LMC Animal Planet shall not, without Purchaser Indemnitee’s consent, agree to any settlement with respect to any Purchaser Loss if such settlement could adversely affect the Tax liability of Purchaser Indemnitee or any of its Affiliates. If LMC Animal Planet assumes such defense, (i) Purchaser Indemnitee shall have the right (but not the duty) to participate in the defense thereof and to employ counsel, at its own expense, separate from the counsel employed by LMC Animal Planet and (ii) LMC Animal Planet shall not assert that the Purchaser Loss, or any portion thereof, with respect to which Purchaser Indemnitee seeks indemnification is not within the ambit of this Section 7.06. If LMC Animal Planet elects not to assume such defense, Purchaser Indemnitee may pay, compromise or contest the Purchaser Loss at issue. LMC Animal Planet shall be liable for the reasonable fees and expenses of counsel employed by Purchaser Indemnitee for any period during which LMC Animal Planet has not assumed the defense thereof. Whether or not LMC Animal Planet chooses to defend or prosecute any claim, all of the parties hereto shall cooperate in the defense or prosecution thereof.

(e) LMC Animal Planet shall not be liable under this Section 7.06 with respect to any Purchaser Loss resulting from a claim or demand the defense of which LMC Animal Planet was not offered the opportunity to assume as provided under Section 7.06(d) to the extent LMC Animal Planet’s liability under this Section 7.06 is materially adversely affected as a result thereof. No investigation by IDT Parent or any of its Affiliates at or prior to the Closing Date shall relieve LMC Animal Planet of any liability hereunder.

(f) Any claim of any Purchaser Indemnitee under this Section 7.06 may be made and enforced by IDT Parent on behalf of such Purchaser Indemnitee.

Section 7.07 Purchase Price Adjustment. Any amount paid by LMC Animal Planet or IDT Parent under this Article 7 or 9 will be treated as an adjustment to the consideration delivered in the Mergers unless a Final Determination or change in Applicable Law (including a revenue ruling or other similar pronouncement) causes any such amount not to constitute an adjustment to the consideration delivered in the Mergers for any applicable Tax purposes.

The failure of any Indemnified Person so to notify an Indemnifying Person of any such action shall not relieve such Indemnifying Person from any liability which it may have to such Indemnified Person, except to the extent such Indemnifying Person shall have been materially prejudiced by the failure of such Indemnified Person so to notify it, pursuant to this Section 9.03. In case any such action shall be brought against any Indemnified Person and it shall notify the Indemnifying Persons of the commencement thereof, the Indemnifying Persons shall be entitled to participate in the defense thereof and, to the extent that the Indemnifying Persons may wish to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Person, and after notice to such Indemnified Person of their election so to assume the defense thereof,

-33-

the Indemnifying Persons will not be liable to such Indemnified Person under this Article 9 for any legal or other expense subsequently incurred by such Indemnified Person in connection with the defense thereof; provided, however, that (i) if the Indemnifying Persons shall elect not to assume the defense of such claim or action or (ii) if the Indemnified Person reasonably determines (x) that there may be a conflict between the positions of the Indemnifying Persons and of the Indemnified Person in defending such claim or action or (y) that there may be legal defenses available to such Indemnified Person different from or in addition to those available to the Indemnifying Persons, then separate counsel for the Indemnified Person shall be entitled to participate in and conduct the defense, in the case of (i) and (ii)(x), or such different defenses, in the case of (ii)(y), and the Indemnifying Persons shall be liable for any reasonable legal or other expenses incurred by the Indemnified Person in connection therewith.

Section 9.04 Exclusivity of Remedy. The indemnification provisions set forth in Articles 7 and 9 are the sole and exclusive remedy for breach of any and all representations and warranties contained in this Agreement; provided, however, that the foregoing indemnification provisions are in addition to, and not in derogation of, any statutory, equitable, or common law remedy any party may have for breach of any and all covenants and agreements contained in this Agreement. Notwithstanding anything in this Agreement to the contrary, neither LMC Animal Planet or any Seller Subsidiary, on the one hand, nor IDT Parent or any IDT Subsidiary, on the other hand, shall be liable to the other for any indirect, punitive, special, consequential or incidental damages under any provision of this Agreement or for any indirect, punitive, special, consequential or incidental damages arising out of any act or failure to act hereunder, even if such party has been advised of or has foreseen the possibility of such damages.

Section 9.05 Certain Limitations. The indemnification obligations of the parties hereto with respect to claims asserted for any breach of a representation or warranty set forth in Article 4 or 5 prior to expiration of the survival period applicable to such representation or warranty shall survive until such claims are finally adjudicated or otherwise resolved.

Section 9.06 Method of Payment for Certain Indemnification Payments. Any indemnification payments to be made by IDT Parent or an IDT Subsidiary pursuant to Article 9 shall be made by delivering shares of IDT Parent Class B Common Stock. Any shares of IDT Parent Class B Common Stock to be delivered pursuant to this Section 9.06 shall be valued based on the weighted average (based on trading volume) of the daily closing prices (as of 4:00 p.m. eastern time) per share of IDT Parent Class B Common Stock as reported on the NYSE (as published in the Wall Street Journal, or if not published therein or incorrectly published therein, in another authoritative source mutually selected by IDT Parent and LMC Animal Planet) for the twenty consecutive trading days ending on the second trading day prior to the date on which such indemnification payment is made by IDT Parent or an IDT Subsidiary. All such shares of IDT Parent Class B Common Stock so delivered pursuant to this Section 9.06 shall be duly authorized, fully paid, and non-assessable, shall be issued in compliance with all Applicable Law and not be subject to any Liens and shall be treated as Registrable
