Any such interest of a Director shall not disqualify him from being counted in determining the existence of a quorum at any meeting nor shall any such interest disqualify him from voting or consenting as a Director or having his vote or consent counted in connection with any such dealing or contract.

No stockholder shall be disqualified from dealing or contracting as vendor, purchaser or otherwise, either in his individual capacity or through any other corporation, trust, association or firm in which he is interested as stockholder, director, trustee, partner or otherwise, with the corporation or any corporation, trust, association or firm in which the corporation shall be a stockholder or otherwise interested or which shall hold stock or be otherwise interested in the corporation, nor shall any such dealing or contract be avoided, nor shall any stockholder so dealing or contracting be liable to account for any profit or benefit realized through any such contract or dealing to the corporation or to any stockholder or creditor thereof by reason of such stockholder holding stock in the corporation to any amount, nor shall any fiduciary relationship be deemed to be established by such stockholding.

At each annual election held after the Special Meeting of Stockholders in Lieu of the 1989 Annual Meeting, the Directors elected to succeed those whose terms expire shall be identified as being of the same class as the Directors they succeed and shall be elected to hold office for a term to expire at the third annual meeting of the stockholders after their election, and until their respective successors are duly elected and qualified: if the number of Directors changes, any increase or decrease in Directors shall be apportioned among the classes so as to maintain all classes as equal in

Such proxy statement shall contain at the front thereof, in a prominent place, any recommendations as to the advisability (or inadvisability) of the Business Combination which the Continuing Directors, or any of them, may have furnished in writing and, if deemed advisable by a majority of the Continuing Directors, an opinion of a reputable investment banking firm as to the fairness (or lack of fairness) of the terms of such Business Combination, from the point of view of the holder of Voting Stock other than an Interested Stockholder (such investment banking firm to be selected by a majority of the Continuing Directors, to be furnished with all information it reasonably requests and to be paid a reasonable fee for its services upon receipt by the corporation of such opinion)

(F) | Notwithstanding any other provisions of these Articles of Organization or the By-laws of the corporation or the fact that a lesser percentage may be specified by law, these Articles of Organization or the By-laws of the corporation, the affirmative vote of the holders of at least eighty (80%) percent of the combined voting power of the then outstanding Voting Stock, voting together as a single class, shall be required to amend, alter, adopt any provision inconsistent with or repeal this Provision; provided however that if any such proposal receives the affirmative vote of each holder of at least 15% of the outstanding Voting Stock who also held at least 15% of the outstanding Voting Stock of the corporation on May 15, 1989, then such proposal shall require only the affirmative vote of the holders of at least a majority of the outstanding Voting Stock of the corporation.

Redemption of Shares

In accordance with Section 6 of Chapter 110D of the General Laws of the Commonwealth of Massachusetts the corporation by action of its Board of Directors is authorized, at the option of the corporation by such Board action but without requiring the agreement of the person who has made a control share acquisition (as defined in said Chapter 110D), to redeem all but not less than all shares acquired in such a control share acquisition in accordance with and subject to the limitations contained in said Chapter 110D including Section 6 thereof.

C-7

Exhibit A

COGNEX CORPORATION

PLAN OF RECAPITALIZATION

June 27, 1989

1. | COMMON STOCK. As of the Effective Date (as defined below), Cognex Corporation (the “Company”) will complete a one-for-two reverse stock split pursuant to which (A) each holder of two (2) shares of the currently issued and outstanding Class A Common Stock, with $.001 par value per share (“Old Class A Stock”) of the Company will be entitled to receive, in exchange therefor, one (1) share of the newly authorized but unissued Class A Common Stock, with $.002 par value per share (“New Class A Stock”) of the Company and (B) each holder of two (2) shares of the currently issued and outstanding Class B Common Stock with $.001 par value per share (“Old Class B Stock”) will be entitled to receive, in exchange therefor, one (1) share of the newly authorized but unissued Class B Common Stock of the Company with $.002 par value per share (“New Class B Stock”). Fractional shares will not be issued by the Company and, in lieu thereof, holders will receive cash in an amount equal to the fair value of that fractional share as of the Effective Date as determined by the Board of Directors of the Company. Stockholders must return for exchange all certificates representing shares of Old Class A Stock and Old Class B Stock in order to receive cash or certificates representing New Class A Stock or New Class B Stock. Accompanying the Notice of the Special Meeting is a Letter of Transmittal for each holder to complete, date, execute and return to the Company together with all certificates representing Old Class A Stock and Old Class B Stock. The Transmittal Letter and the certificates will be held by the Company until the Plan of Recapitalization is approved. Certificates representing the New Class A Stock and New Class B Stock need not be issued in the event that the Company completes the total conversion of all of its capital stock to a single series and class of Common Stock. In such event, certificates representing such single class of Common Stock will be issued. If the Plan is not approved, the certificates and the Transmittal Letter will be returned to the holder.

2. | PREFERRED STOCK. As a result of the reverse stock split approved in paragraph 1 above, the conversion rates for the Company’s currently authorized Preferred Stock shall be adjusted (and Article 4 of the Articles of Organization of the Company shall be amended) as follows: (A) the applicable Conversion Rate for the Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock, upon the consummation of the reverse stock split, shall be five (5) such that each share of Series A, B and C Preferred Stock converts into five (5) shares of New Class A Stock and (B) the applicable Conversion Rate for the Series D Preferred Stock, upon the consummation of the reverse stock split, shall be one-half (1/2) such that each share of Series D Preferred Stock shall convert into one-half (1/2) share of New Class A Stock.

3. | AMENDMENTS TO ARTICLES OF ORGANIZATION. As a result of the reverse stock split approved in paragraph 1 above, by adoption of this Plan of Recapitalization, the Articles of Organization of the Company are amended such that the total number of shares and the par value, if any, of the Common Stock that the Company is authorized to issue shall be changed from 10,000,000 shares of Class A Common Stock with $.001 par value per share and 2,500,000 shares of Class B Common Stock with $.001 par value per share to 5,000,000 shares of Class A Common Stock with $.002 par value per share and 1,250,000 shares of Class B Common Stock with $.002 par value per share. In addition, by adoption of this Plan of Recapitalization, the Articles of Organization are hereby further amended to increase the number of shares of Class A Common Stock that the Corporation is authorized to issue from 5,000,000 shares with $.002 par value per share to 10,000,000 shares with $.002 par value per share (such new shares to be known as “Common Stock”). The Company need not file two separate Articles of Amendment to reflect these amendments and may make one filing with the Secretary of the Commonwealth of Massachusetts showing the ultimate effect to the Articles of Organization of this Plan of Recapitalization.

4. | EFFECTIVE DATE. As used herein, the term “Effective Date” shall mean June 28, 1989.

*We further certify that the foregoing restated articles of organization effect no amendments to the articles of organization of the corporation as heretofore amended, except amendments to the following articles

Article 3, Article 4 and Article 6

(*If there are no such amendments, state “None”.)

Briefly describe amendments in space below:

1. | Adopted the Cognex Corporation Plan of Recapitalization on June 27, 1989 (see Exhibit A hereto), following which the only shares of capital stock which the Corporation shall have authority to issue shall be 10,000,000 shares of a single class of Common Stock having a par value of $.002 per share and 400,000 shares of Preferred Stock par value $.01 per share, all the previously issued Class A and Class B Common Stock and the Series A, B, C and D Preferred Stock having been converted into shares of a single class of Common Stock.
