ARTICLE III
THE MERGER AND RELATED MATTERS

     Section 3.01 The Merger.

          (a) Merger; Effective Time of the Merger. At the Effective Time of the Merger and subject to and upon the terms and conditions of this Agreement, Merger Sub will merge with and into DHC in accordance with the provisions of the General Corporation Law of the State of Delaware (“DGCL”), the separate corporate existence of Merger Sub will cease and DHC will continue as the surviving entity (the “Surviving Entity”). The Effective Time of the Merger will be on the date and at the time that the certificate of merger with respect to the Merger, containing the provisions required by and executed in accordance with Section 251 of the DGCL (the “Certificate of Merger”), has been accepted for filing by the Delaware Secretary of State, and all other documents required by the DGCL to effectuate the Merger will have been properly executed and filed (or such later date and time as may be specified in the Certificate of Merger).

          (b) Effects of the Merger. From and after the Effective Time of the Merger, the Merger will have the effects set forth in the DGCL (including Sections 259, 260 and 261 thereof). Without limiting the generality of the foregoing, and subject thereto, at the Effective Time of the Merger, all the properties, rights, privileges, powers and franchises of DHC and Merger Sub will vest in the Surviving Entity, and all debts, liabilities and duties of DHC and Merger Sub will, by operation of law, become the debts, liabilities and duties of the Surviving Entity.

          (c) Certificate of Incorporation of the Surviving Entity. At the Effective Time of the Merger, the Amended and Restated Certificate of Incorporation of DHC (the “DHC Charter”) will be amended pursuant to the Certificate of Merger to be identical to the Certificate of Incorporation of Merger Sub in effect immediately prior to the Effective Time of the Merger, except that Article FIRST thereof will read as follows: “The name of the Corporation (which is hereinafter called the “Corporation”) is Discovery Holding Company”. Such DHC Charter as so amended will be the Certificate of Incorporation of the Surviving Entity until thereafter duly amended or restated in accordance with the terms thereof and the DGCL.

          (d) Bylaws of the Surviving Entity. At the Effective Time of the Merger, the Restated Bylaws of DHC (the “DHC Bylaws”) will be amended to be identical to the bylaws of Merger Sub in effect immediately prior to the Effective Time of the Merger and, in such amended form, will be the Bylaws of the Surviving Entity until thereafter duly amended or restated in accordance with the terms thereof, the terms of the Certificate of Incorporation of the Surviving Entity and the DGCL.

     Section 3.02 Conversion of Securities.

          (a) Conversion of DHC Securities. At the Effective Time of the Merger, by virtue of the Merger and without any action on the part of any party hereto or any holder of shares of DHC Common Stock:

          (i) each share of DHC Series A Common Stock issued and outstanding immediately prior to the Effective Time of the Merger (together with the DHC Series A Right attached thereto) will be converted into and represent the right to receive, and will be exchangeable for, 0.50 shares of New DHC Series A Common Stock and 0.50 shares of New DHC Series C Common Stock (the “Series A Consideration”);

          (ii) each share of DHC Series B Common Stock (together with the DHC Series B Right attached thereto) issued and outstanding immediately prior to the Effective Time of the Merger will be converted into and represent the right to receive, and will be exchangeable for, 0.50 shares of New DHC Series B Common Stock and 0.50 shares of New DHC Series C Stock (the “Series B Consideration”, which, together with the Series A Consideration, is the “Consideration”); and

          (iii) each share of DHC Common Stock held in treasury of DHC immediately prior to the Effective Time of the Merger will be cancelled and retired without payment of any consideration therefor and without any conversion thereof.

     At the Effective Time, all shares of DHC Common Stock issued and outstanding immediately prior to the Effective Time will no longer be outstanding and will automatically be canceled and retired and will cease to exist, and each holder of a Certificate or Book-Entry Share will have no further rights with respect thereto, except as set forth in Section 3.03.

          (b) Conversion of Merger Sub Stock. At the Effective Time of the Merger, by virtue of the Merger and without any action on the part of any party hereto or any holder of shares of stock of Merger Sub, each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time of the Merger will be converted into and become one validly issued, fully paid and nonassessable share of common stock of the Surviving Entity. Such shares will constitute the only outstanding shares of capital stock of the Surviving Entity.

          (c) Treatment of New DHC Securities. At the Effective Time of the Merger, by virtue of the Merger and without any action on the part of any party hereto, each share of New DHC Original Stock held by DHC will be cancelled and retired and will cease to exist.

     Section 3.03 Exchange Procedures.

          (a) Exchange of Certificates.

          (i) As soon as reasonably practicable after the Effective Time of the Merger, New DHC will cause to be mailed to (x) each record holder, as of the Effective Time of the Merger, of Certificates (such holders, “Former Certificate Holders” and such shares, “Former Certificated Shares”): (A) a letter of transmittal (which will specify that delivery will be effected, and risk of loss and title to the Certificates held by such holder representing such Former Certificated Shares will pass, only upon proper

delivery of the Certificates to the Exchange Agent) and (B) instructions for use in effecting the surrender of the Certificates for the Consideration. Such letter of transmittal will be in such form and have such other reasonable provisions as New DHC may specify.

          (ii) Upon surrender by a Former Certificate Holder to the Exchange Agent of a Certificate, together with a letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, each Former Certificate Holder will be entitled to receive in exchange therefor: (A) the number of whole shares of New DHC Common Stock into which such holder’s shares of DHC Common Stock represented by such holder’s properly surrendered Certificates were converted in accordance with this Article III, and such Certificates so surrendered will be forthwith cancelled, (B) a check in an amount of U.S. dollars (after giving effect to any required withholdings pursuant to Section 3.03(e)) equal to any cash consideration in lieu of fractional shares to which such holder is entitled pursuant to Section 3.03(d), and (C) any unpaid dividends or distributions which such holder is entitled to receive.

          (iii) If issuance of the Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate is registered, it will be a condition of payment or issuance that the Certificate so surrendered will be properly endorsed or will be otherwise in proper form for transfer and that the Person requesting such payment or issuance will have paid to the Exchange Agent any transfer and other taxes required by reason of the payment or issuance of the Consideration to a Person other than the registered holder of the Certificate surrendered or will have established to the satisfaction of the Exchange Agent that such tax either has been paid or is not applicable. In the event that any Certificate will have been lost, stolen or destroyed, upon the holder’s compliance with the replacement requirements established by the Exchange Agent, including, if necessary, the posting by the holder of a bond in customary amount as indemnity against any claim that may be made against it with respect to the Certificate, the Exchange Agent will deliver in exchange for the lost, stolen or destroyed Certificate the applicable Consideration payable in respect of the shares of DHC Common Stock represented by the Certificate pursuant to this Article III, together with any cash or other consideration to which such holder is entitled.

          (iv) Until surrendered as contemplated hereby, each Certificate will, after the Effective Time of the Merger, represent for all purposes only the right to receive upon such surrender the applicable Consideration as contemplated by this Article III, together with any cash or other consideration to which such holder is entitled.

          (v) At the Effective Time of the Merger, the stock transfer books of DHC will be closed, and thereafter there will be no further registration of transfers of shares of DHC Common Stock, that were outstanding prior to the Effective Time of the Merger. After the Effective Time of the Merger, Certificates presented to DHC for transfer will be canceled and exchanged for the applicable Consideration in accordance with the procedures set forth in this Article III, together with any cash or other consideration to which such holder is entitled.

          (b) Treatment of Book-Entry Shares. As soon as reasonably practicable after the Effective Time of the Merger, New DHC will cause to be mailed to (x) each record holder, as of the Effective Time of the Merger, of Book-Entry Shares (such holders, “Former Book-Entry Holders” and together with Former Certificate Holders, “Former DHC Holders,” and such shares, “Former Book-Entry Shares” and together with Former Certificated Shares, “Former DHC Shares”): (A) a statement of holdings which will state the number of whole shares of New DHC Common Stock into which such Former Book Entry Holder’s shares of DHC Common Stock were converted in accordance with this Article III, and (B) a check in an amount of U.S. dollars (after giving effect to any required withholdings pursuant to Section 3.03(e)) equal to any cash consideration to which such holder is entitled hereunder.

          (c) Distributions With Respect to Unexchanged Shares. No dividends or other distributions with respect to shares of New DHC Common Stock issuable with respect to Former Certificated Shares will be paid to the holder of any unsurrendered Certificates until those Certificates are surrendered as provided in this Article III. Upon surrender, there will be issued and/or paid to the holder of the shares of New DHC Common Stock issued in exchange therefor, without interest, (i) at the time of surrender, the dividends or other distributions payable with respect to those shares of New DHC Common Stock with a record date on or after the date of the Effective Time of the Merger and a payment date on or prior to the date of such surrender and not previously paid and (ii) at the appropriate payment date, the dividends or other distributions payable with respect to those shares of New DHC Common Stock with a record date on or after the date of the Effective Time of the Merger but with a payment date subsequent to surrender.

          (d) No Fractional Shares. No certificates or scrip representing fractional shares of New DHC Common Stock will be issued with respect to Book-Entry Shares evidencing DHC Common Stock or upon the surrender for exchange of Certificates, and such fractional share interests will not entitle the owner thereof to vote or to any rights of a stockholder of New DHC. In lieu thereof, upon surrender of the applicable Certificates or upon conversion of Book-Entry Shares, New DHC will pay each holder of DHC Common Stock an amount in cash equal to the product obtained by multiplying (i) the fractional share interest of the series of New DHC Common Stock to which such holder would otherwise be entitled, by (ii) the closing price for a share of such stock on the first trading day on which shares of New DHC Common Stock trade in the regular way market.

          (e) Withholding. New DHC and the Exchange Agent will be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of DHC Common Stock such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code and the Treasury Regulations promulgated thereunder, or any provision of state, local or foreign tax law. To the extent that amounts are so withheld by New DHC or the Exchange Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of DHC Common Stock in respect of which such deduction and withholding was made by New DHC or the Exchange Agent.

     Section 3.04 Stock Incentive Plans; Treatment of Outstanding DHC Common Stock Options.

          (a) Assumption of Plans and Awards.

As of the Effective Time of the Merger, each DHC Award will be assumed (as assumed, a “Replacement Award”) by New DHC and will thereafter be exercisable for or relate to shares of New DHC Common Stock, as more particularly described in Section 3.04(b).

          (b) DHC Common Stock Options.

          (i) At the Effective Time of the Merger, each of the then outstanding stock options, if any, to purchase shares of DHC Series A Common Stock set forth on Schedule 3.04(b) hereto (each, a “Scheduled Series A Option”) issued by DHC pursuant to the DHC Incentive Plans, will, by virtue of the AMG Spin-Off (as defined in the Transaction Agreement) and the Merger, and without any further action on the part of any holder thereof, be converted into (A) an option (a “Converted Series A Option”) to purchase shares of New DHC Series A Common Stock in an amount and at an exercise price as determined below, (B) an option (a “Series C Option”) to purchase shares of New DHC Series C Common Stock in an amount and at an exercise price as determined below, and (C) an option (a “Spin-Off Company Series A Option”) to purchase shares of Series A common stock of the Spin-Off Company in an amount and at an exercise price as determined below. The exercise price of such Converted Series A Option, Series C Option and Spin-Off Company Series A Option will be equal to the applicable VWAP for the series of common stock subject to such option, multiplied by a fraction, the numerator of which is the exercise price of such Scheduled Series A Option and the denominator of which is the VWAP for the DHC Series A Common Stock. The number of shares of New DHC Series A Common Stock, New DHC Series C Common Stock and Series A common stock of the Spin-Off Company subject to the Converted Series A Option, Series C Option and Spin-Off Company Series A Option, as applicable, will be determined so that the aggregate amount by which the Scheduled Series A Option was “in-the-money” or “out-of-the-money”, as applicable, immediately prior to the Transactions (determined according to the VWAP for the DHC Series A Common Stock) is preserved immediately following the Transactions (allocating such aggregate “in-the-money” or “out-of-the-money” amounts according to the applicable VWAP for the New DHC Series A Common Stock, New DHC Series C Common Stock and Series A common stock of the Spin-Off Company). The terms and conditions of each Converted Series A Option, Series C Option and Spin-Off Company Series A Option, including vesting conditions (which will not be accelerated by the Transactions) and the scheduled expiration date, will otherwise remain as set forth in the Scheduled Series A Option converted into such Converted Series A Option, Series C Option and Spin-Off Company Series A Option. If the foregoing calculation results in a Converted Series A Option, Series C Option or Spin-Off Company Series A Option being exercisable for a fraction of a share of New DHC Series A Common Stock, New DHC Series C Common Stock or Series A common stock of the Spin-Off Company, as applicable, then the number of shares of New DHC Series A Common Stock, New DHC Series C Common Stock or Series A common stock

of the Spin-Off Company, as applicable, subject to such option will be rounded down to the nearest whole number of shares, with no cash being payable for such fractional share.

          (ii) At the Effective Time of the Merger, each of the then outstanding stock options, if any, to purchase shares of DHC Series A Common Stock (excluding any Scheduled Series A Options and any such options that are, at the option of the holder, exercisable for shares of DHC Series A Common Stock or DHC Series B Common Stock) held by those members of the DHC Board (other than those directors that hold Scheduled Series A Options) as of the date of this Agreement who will be directors of New DHC immediately after the Effective Time of the Merger (each, a “Director Series A Option,” any such director, and any director that holds a Scheduled Series A Option, a “Carryover Director”) issued by DHC pursuant to the DHC Incentive Plans, will, by virtue of the AMG Spin-Off and the Merger, and without any further action on the part of any holder thereof, be converted into (A) a Converted Series A Option to purchase shares of New DHC Series A Common Stock in an amount and at an exercise price as determined below, and (B) a Series C Option to purchase shares of New DHC Series C Common Stock in an amount and at an exercise price as determined below. The exercise price of such Converted Series A Option and Series C Option will be equal to the applicable VWAP for the series of common stock subject to such option, multiplied by a fraction, the numerator of which is the exercise price of such Director Series A Option and the denominator of which is the VWAP for the DHC Series A Common Stock. The number of shares of New DHC Series A Common Stock and New DHC Series C Common Stock subject to the Converted Series A Option and Series C Option, as applicable, will be determined so that the aggregate amount by which the Director Series A Option was “in-the-money” or “out-of-the-money”, as applicable, immediately prior to the Transactions (determined according to the VWAP for the DHC Series A Common Stock) is preserved immediately following the Transactions (allocating such aggregate “in-the-money” or “out-of-the-money” amounts according to the applicable VWAP for the New DHC Series A Common Stock and New DHC Series C Common Stock). The terms and conditions of each Converted Series A Option and Series C Option, including vesting conditions (which will not be accelerated by the Transactions) and the scheduled expiration date, will otherwise remain as set forth in the Director Series A Option converted into such Converted Series A Option and Series C Option. If the foregoing calculation results in a Converted Series A Option or a Series C Option being exercisable for a fraction of a share of New DHC Series A Common Stock or New DHC Series C Common Stock, as applicable, then the number of shares of New DHC Series A Common Stock or New DHC Series C Common Stock, as applicable, subject to such option will be rounded down to the nearest whole number of shares, with no cash being payable for such fractional share.

          (iii) At the Effective Time of the Merger, each of the then outstanding stock options, if any, to purchase shares of DHC Series A Common Stock other than the Director Series A Options and the Scheduled Series A Options (each, a “Series A Option”) issued by DHC pursuant to the DHC Incentive Plans, will, by virtue of the AMG Spin-Off and the Merger, and without any further action on the part of any holder thereof, be converted into (A) a stock appreciation right (a “Series A SAR”) with respect to that number of shares of New DHC Series A Common Stock and at such base price as

determined below, and (B) a stock appreciation right (a “Series C SAR” and, together with the Series A SARs, the “Rollover SARs”) with respect to that number of shares of New DHC Series C Common Stock and at such base price as determined below. The base price of each Series A SAR and Series C SAR will be equal to the applicable VWAP for the series of common stock subject to such Rollover SAR, multiplied by a fraction, the numerator of which is the exercise price of such Series A Option and the denominator of which is the VWAP for the DHC Series A Common Stock. The number of shares of New DHC Series A Common Stock and New DHC Series C Common Stock to which the Series A SAR and Series C SAR, as applicable, relate will be determined so that the aggregate amount by which the Series A Option was “in-the-money” or “out-of-the-money”, as applicable, immediately prior to the Transactions (determined according to the VWAP for the DHC Series A Common Stock) is preserved immediately following the Transactions (allocating such aggregate “in-the-money” or “out-of-the-money” amounts according to the applicable VWAP for the New DHC Series A Common Stock and New DHC Series C Common Stock). The terms and conditions of each Series A SAR and Series C SAR, including vesting conditions (which will not be accelerated by the Transactions) and the scheduled expiration date, will otherwise remain as set forth in the Series A Option converted into such Series A SARs and Series C SARs, except that, the spread between the Fair Market Value of the underlying shares and the base price of each Series A SAR and Series C SAR will be payable solely in shares of New DHC Series A Common Stock or New DHC Series C Common Stock, as applicable (with such shares of New DHC Common Stock valued at the Fair Market Value of shares of New DHC Series A Common Stock or New DHC Series C Common Stock, as applicable, on the date of exercise). If the foregoing calculation results in a Series A SAR or a Series C SAR being exercisable for a fraction of a share of New DHC Series A Common Stock or New DHC Series C Common Stock, as applicable, then the number of shares of New DHC Series A Common Stock or New DHC Series C Common Stock, as applicable, subject to such SAR will be rounded down to the nearest whole number of shares, with no cash being payable for such fractional share.

          (iv) At the Effective Time of the Merger, each of the then outstanding stock options, if any, to purchase shares of DHC Series B Common Stock (including any such options that are, at the option of the holder, exercisable for shares of DHC Series B Common Stock or DHC Series A Common Stock) held by any Carryover Director (each, a “Series B Option”) issued by DHC pursuant to the DHC Incentive Plans, will, by virtue of the AMG Spin-Off and the Merger, and without any further action on the part of any holder thereof, be converted into (A) an option (a “Converted Series B Option” and, together with the Converted Series A Options and Series C Options, the “Converted Options”) to purchase shares of New DHC Series B Common Stock in an amount and at an exercise price as determined below, (B) a Series C Option to purchase shares of New DHC Series C Common stock in an amount and at an exercise price as determined below, and (C) an option (a “Spin-Off Company Series B Option”) to purchase shares of Series B common stock of the Spin-Off Company in an amount and at an exercise price as determined below. The exercise price of such Converted Series B Option, Series C Option and Spin-Off Company Series B Option will be equal to the applicable VWAP for the series of common stock subject to such option, multiplied by a fraction, the numerator of which is the exercise price of the Series B Option and the denominator of which is the

VWAP for the DHC Series B Common Stock. The number of shares of New DHC Series B Common Stock, New DHC Series C Common Stock and Series B common stock of the Spin-Off Company subject to the Converted Series B Option, Series C Option and Spin-Off Company Series B Option, as applicable, will be determined so that the aggregate amount by which the Series B Option was “in-the-money” or “out-of-the-money”, as applicable, immediately prior to the Transactions (determined according to the VWAP for the DHC Series B Common Stock) is preserved immediately following the Transactions (allocating such aggregate “in-the-money” or “out-of-the-money” amounts according to the applicable VWAP for the New DHC Series B Common Stock, New DHC Series C Common Stock and Series B common stock of the Spin-Off Company). The terms and conditions of each Converted Series B Option, Series C Option and Spin-Off Company Series B Option, including vesting conditions (which will not be accelerated by the Transactions) and the scheduled expiration date, will otherwise remain as set forth in the Series B Option converted into such Converted Series B Option, Series C Option and Spin-Off Company Series B Option. If the foregoing calculation results in a Converted Series B Option, a Series C Option or a Spin-Off Company Series B Option being exercisable for a fraction of a share of New DHC Series B Common Stock, New DHC Series C Common Stock or Series B common stock of the Spin-Off Company, as applicable, then the number of shares of New DHC Series B Common Stock, New DHC Series C Common Stock or Series B common stock of the Spin-Off Company, as applicable, subject to such option will be rounded down to the nearest whole number of shares, with no cash being payable for such fractional share.

          (v) Notwithstanding the foregoing, DHC may, in its sole discretion, cancel any or all outstanding Director Series A Options, Scheduled Series A Options, Series A Options or Series B Options prior to or as of the Effective Time of the Merger for such cash or other consideration as may be determined to be appropriate by the DHC Board.

     Section 6.08 Severability. Each provision of this Agreement will be considered separable and if for any reason any provision of this Agreement, or the application thereof, becomes or is declared by a court of competent jurisdiction to be illegal, void or unenforceable, the remainder of this Agreement will continue in full force and effect and the application of such provision to other Persons or circumstances will be interpreted so as reasonably to effect the intent of the parties hereto.

     Section 6.09 Governing Law. This Agreement will be governed by and construed in accordance with the laws of the State of Delaware without giving effect to the conflicts of law principles thereof.

Each party agrees that service of any process, summons, notice or document by U.S. registered mail to such party’s respective address in accordance with Section 6.01 will be effective service of process for any action, suit or proceeding in Delaware with respect to any matters to which it has submitted to jurisdiction in this Section 6.10. Each party hereto irrevocably and unconditionally waives and agrees not to plead or claim any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably and unconditionally waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum.

     Section 6.12 Specific Performance. Each of the parties to this Agreement agrees that the other parties hereto would be irreparably damaged if any of the provisions of this Agreement are not performed in accordance with its specific terms and that monetary damages would not provide an adequate remedy in such event. Accordingly, in addition to any other remedy to which the nonbreaching parties may be entitled, at law or in equity, the nonbreaching parties may be entitled to injunctive relief to prevent breaches of this Agreement and to specifically enforce the terms and provisions hereof.

     Section 6.13 Amendments. This Agreement may be amended by an instrument in writing signed on behalf of each of the parties hereto at any time before or after the adoption of this Agreement by their respective stockholders; provided, however, that after any such adoption, there will be made no amendment that by Law requires further approval by such stockholders without the further approval of such stockholders.

     Section 6.14 Interpretation. When a reference is made in this Agreement to Exhibits, Schedules, Articles or Sections, such reference will be to an Exhibit, Schedule, Article or Section to this Agreement unless otherwise indicated. The words “include,” “includes,” “included,” and “including,” when used herein will be deemed in each case to be followed by the words “without limitation.” The words “hereof,” “herein,” “hereby,” and “hereunder” and words of similar import when used in this Agreement will refer to this Agreement as a whole and not to any particular provision of this Agreement. The words “date hereof” will refer to the date of this Agreement. The term “or” is not exclusive and means “and/or” unless the context in which such phrase is used will dictate otherwise. The word “extent” in the phrase “to the extent” will mean the degree to which a subject or other such thing extends, and such phrase will not mean simply “if” unless the context in which such phrase is used dictates otherwise. The definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms and to the masculine as well as to the feminine and neuter genders of such term. The Article and Section headings contained in this Agreement are for reference purposes only and will not affect in any way the meaning or interpretation of this Agreement. Whenever the context may require, any pronoun will include the corresponding masculine, feminine and neuter forms. Any reference in this Agreement to a Person will be deemed to be a reference to such Person and any successor (by merger, consolidation, transfer or otherwise) to all or substantially all its assets.

     Section 6.15 Rules of Construction. Each of the parties to this Agreement agrees that they have been represented by counsel during the negotiation, preparation and execution of this Agreement and, therefore, waive the application of any law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the party drafting such agreement or document.
