II. CHARTER DOCUMENTS, DIRECTORS AND OFFICERS 2.1 Certificate of Incorporation. The Certificate of Incorporation of Altera-Delaware as in effect immediately prior to the Effective Date of the Merger shall continue in full force and effect as the Certificate of Incorporation of the Surviving Corporation until duly amended in accordance with the provisions thereof and of applicable law. 2.2 Bylaws. The Bylaws of Altera-Delaware as in effect immediately prior to the Effective Date of the Merger shall continue in full force and effect as the Bylaws of the Surviving Corporation until duly amended in accordance with the provisions thereof and applicable law. 2.3 Directors.

III. MANNER OF CONVERSION OF STOCK 3.1 Altera-California Common Shares. Upon the Effective Date of the Merger, each share of Altera-California Common Stock issued and outstanding immediately prior thereto shall by virtue of the Merger and without any action by the Constituent Corporations, the holder of such shares or any other person, be converted into and exchanged for one (1) fully paid and nonassessable share of Common Stock, $0.001 par value, of the Surviving Corporation. 3.2 Altera-California Options, Stock Purchase Rights and Convertible Securities. (a) Upon the Effective Date of the Merger, the Surviving Corporation shall assume the obligations of Altera-California under, and continue, its 1987 Stock Option Plan, 1996 Stock Option Plan, 1988 Director Option Plan, 1987 Employee Stock Purchase Plan and all other employee benefit plans of Altera-California. Each outstanding and unexercised option, other right to purchase, or security convertible into, Altera-California Common Stock (a "Right") shall become, subject to the provisions in Section 3.2(c), an option, right to purchase or a security convertible into the Surviving Corporation's Common Stock on the basis of one (1) share of the Surviving Corporation's Common Stock for each one (1) share of Altera-California Common Stock issuable pursuant to any such Right, on the same terms and conditions and at an exercise price equal to the exercise price applicable to any such Altera-California Right at the Effective Date of the Merger. This 2 3 Section 3.3(a) shall not apply to outstanding shares of Altera-California Common Stock. Such outstanding shares of Common Stock are subject to Section 3.1. (b) A number of shares of the Surviving Corporation's Common Stock shall be reserved for issuance upon the exercise of options, stock purchase rights and convertible securities equal to the number of shares of Altera-California Common Stock so reserved immediately prior to the Effective Date of the Merger. (c) The assumed Rights shall not entitle any holder thereof to a fractional share upon exercise or conversion (unless the holder was entitled to a fractional interest immediately prior to the Merger). In lieu thereof, any fractional share interests to which a holder of an assumed Right would otherwise be entitled upon exercise or conversion shall be aggregated (but only with other similar Rights which have the same per share terms). To the extent that after such aggregation, the holder would still be entitled to a fractional share with respect thereto upon exercise or conversion, the holder shall be entitled upon the exercise or conversion of all such assumed Rights pursuant to their terms (as modified herein), to one full share of Common Stock in lieu of such fractional share. With respect to each class of such similar Rights, no holder will be entitled to more than one full share in lieu of a fractional share upon exercise or conversion. Notwithstanding the foregoing, with respect to options issued under the Altera-California's 1987 and 1996 Stock Option Plans, as amended, that are assumed in the Merger, the number of shares of Common Stock to which the holder would be otherwise entitled upon exercise of each such assumed option following the Merger shall be rounded down to the nearest whole number and the exercise price shall be rounded up to the nearest whole cent. In addition, no "additional benefits" (within the meaning of Section 424(a)(2) of the Internal Revenue Code of 1986, as amended) shall be accorded to the optionees pursuant to the assumption of their options. 3.3 Altera-Delaware Common Stock. Upon the Effective Date of the Merger, each share of Common Stock, $0.001 par value, of Altera-Delaware issued and outstanding immediately prior thereto shall, by virtue of the Merger and without any action by Altera-Delaware, the holder of such shares or any other person, be canceled and returned to the status of authorized but unissued shares. 3.4 Exchange of Certificates. After the Effective Date of the Merger, each holder of an outstanding certificate representing shares of Altera-California Common Stock may be asked to surrender the same for cancellation to an exchange agent, whose name will be delivered to holders prior to any requested exchange (the "Exchange Agent"), and each such holder shall be entitled to receive in exchange therefor a certificate or certificates representing the number of shares of the Surviving Corporation's Common Stock, as the case may be, into which the surrendered shares were converted as herein provided. Until so surrendered, each outstanding certificate theretofore representing shares of Altera-California Common Stock shall be deemed for all purposes to represent the number of shares of the Surviving Corporation's Common Stock into which such shares of Altera-California Common Stock were converted in the Merger. The registered owner on the books and records of the Surviving Corporation or the Exchange Agent of any such outstanding certificate shall, until such certificate shall have been surrendered for transfer or conversion or otherwise accounted for to the Surviving Corporation or the Exchange Agent, have and be entitled to exercise any voting and other rights with respect to and to receive dividends and other distributions upon the shares of Common Stock of the Surviving Corporation represented by such outstanding certificate as provided above. Each certificate representing Common Stock of the Surviving Corporation so issued in the Merger shall bear the same legends, if any, with respect to the restrictions on transferability as the certificates of Altera-California so converted and given in exchange therefore, unless otherwise determined by the Board of Directors of the Surviving Corporation in compliance with applicable laws. If any certificate for shares of the Surviving Corporation's stock is to be issued in a name other than that in which the certificate surrendered in exchange therefor is registered, it shall be a condition of issuance thereof that the certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer, that such transfer otherwise be proper and comply with applicable securities laws and that the person requesting such transfer pay to the Exchange Agent any transfer or other taxes payable by reason of issuance 3 4 of such new certificate in a name other than that of the registered holder of the certificate surrendered or establish to the satisfaction of the Surviving Corporation that such tax has been paid or is not payable. IV. GENERAL 4.1 Covenants of Altera-Delaware. Altera-Delaware covenants and agrees that it will, on or before the Effective Date of the Merger: (a) Qualify to do business as a foreign corporation in the State of California and in connection therewith irrevocably appoint an agent for service of process as required under the provisions of Section 2105 of the California General Corporation Law. (b) File any and all documents with the California Franchise Tax Board necessary for the assumption by Altera-Delaware of all of the franchise tax liabilities of Altera-California. (c) Take such other actions as may be required by the California General Corporation Law. 4.2 Further Assurances.
