EXHIBIT 4.1 MANCHESTER EQUIPMENT CO., INC. AMENDED AND RESTATED 1996 INCENTIVE AND NON-INCENTIVE STOCK OPTION PLAN 1. Purpose of Plan. The purpose of this Amended and Restated 1996 Incentive and Non-Incentive Stock Option Plan ("Plan") is to further the growth and development of Manchester Equipment Co., Inc. ("Company") and any direct and indirect subsidiaries thereof (collectively, "Subsidiaries" and each, singly, a "Subsidiary") by encouraging selected employees, directors and other persons who contribute and are expected to contribute materially to the Company's success to obtain a proprietary interest in the Company through the ownership of stock, thereby providing such persons with an added incentive to promote the best interests of the Company and affording the Company a means of attracting to its service persons of outstanding ability. 2. Stock Subject to this Plan. An aggregate of 1,100,000 shares of the Company's Common Stock, par value $.01 per share ("Common Stock"), subject, however, to adjustment or change pursuant to Article 10 hereof, shall be reserved for issuance upon the exercise of options which may be granted from time to time in accordance with this Plan ("Options"). Such shares may be, in whole or in part, authorized but unissued shares or issued shares which have been reacquired by the Company. If, for any reason, an Option shall lapse, expire or terminate without having been exercised in full, the unpurchased shares covered thereby shall again be available for purposes of this Plan. 3. Administration. (a) The Board of Directors of the Company shall have and may exercise any and all of the powers relating to the administration of this Plan and the grant of Options hereunder as are set forth herein. (b) The Board shall administer this Plan and, subject to the provisions of this Plan, shall have sole authority in its discretion to determine the persons to whom, and the time or times at which, Options shall be granted, the number of shares to be subject to each such Option and whether all or any portion of such Options shall be incentive stock options ("Incentive Options") qualifying under Section 422 of the Internal Revenue Code of 1986, as amended ("Code"), or stock options which do not so qualify ("Non-Incentive Options"). Both Incentive Options and Non-Incentive Options may be granted to the same person at the same time provided each type of Option is clearly designated. In making such determinations, the Board may take into account the nature of the services rendered by such persons, their present and potential contributions to the Company's success and such other factors as the Board in its sole discretion may deem relevant. Subject to the express provisions of this Plan, the Board shall also have the authority to interpret this Plan, to prescribe, amend and rescind rules and regulations relating thereto, to determine the terms and provisions of the respective Option Agreements, which shall be, subject to the rights granted to the Company and the Board hereunder, substantially in the forms attached hereto as Exhibit A and Exhibit B, with such changes thereto as may be necessary to reflect the terms and conditions of the grant in question, and to make all other determinations necessary or advisable for the administration of this Plan, all of which determinations shall be conclusive and not subject to review. 4. Eligibility for Receipt of Options. (a) Incentive Options. Incentive Options may be granted only to employees (including officers) of the Company and/or any of its Subsidiaries. The aggregate Fair Market Value (as defined in Article 5 of this Plan), determined as of the time the Incentive Option is granted, of the shares of the Company's Common Stock purchasable hereunder exercisable for the first time by an employee during any calendar year may not exceed $100,000. A director of the Company or any Subsidiary who is not an employee of the Company or of one of its Subsidiaries is not eligible to receive Incentive Options under this Plan. Further, Incentive Options may not be granted to any person who, at the time the Incentive Option is granted, owns (or is considered as owning within the meaning of Section 424(d) of the Code) stock possessing more than 10% of the total combined voting powers of all classes of stock of the Company or any Subsidiary (a "10% Owner"), unless at the time the Incentive Option is granted to a 10% Owner, the option price is at least 110% of the fair market value of the Common Stock subject thereto and such Incentive Option by its terms is not exercisable subsequent to five years from the date of grant. (b) Non-Incentive Options. Non-Incentive Options may be granted to any employees (including employees who have been granted Incentive Options), directors, consultants, agents, independent contractors and other persons whom the Board determines will contribute to the Company's success. (c) Notwithstanding the forgoing, the maximum aggregate number of shares with respect to which Options, whether Incentive or Non-Incentive, may be granted to any person eligible therefor under this Plan within any one calendar year is 200,000 shares. 5. Option Price. The purchase price of the shares of Common Stock under each Option shall be determined by the Board, which determination shall be conclusive and not subject to review, but in no event shall such purchase price be less than (i) 100% of the fair market value of the Common Stock on the date of grant of Incentive Options (110% of the fair market value of Common Stock on the date of grant where the grant of Incentive Options is made to a 10% Owner), and (ii) 85% of the fair market value of the Common Stock on the date of grant for Non-Incentive Options. In determining the fair market value of the Common Stock as of a specified date ("Fair Market Value"), the Board shall consider, if the Common Stock is: (a) publicly traded and listed on the New York Stock Exchange or another national securities exchange or The Nasdaq Stock Market, the closing sale price of the Common Stock on the business day immediately preceding the date as of which the Fair Market Value is being determined, or on the next preceding date on which such Common Stock is traded if no Common Stock was traded on such immediately preceding business day, or, if the Common Stock is not so listed on a national securities exchange or The Nasdaq Stock Market, but publicly traded, the representative closing sale price in the over-the-counter market as quoted by the National Quotation Bureau or a recognized dealer in the Common Stock, on the date immediately preceding the date as of which the Fair Market Value is being determined, or on the next preceding date on which such Common Stock is traded if no Common Stock was traded on such immediately preceding business day; or (b) not publicly traded, the fair market value as determined by the Board in good faith based on such factors as it shall deem appropriate. The Board may also consider such other factors as it shall deem appropriate. For purposes of this Plan, the date of grant of an Option shall be the date on which the Board shall by resolution duly authorize such Option. 6. Term of Options; Termination. (a) The term of each Option shall be such number of years as the Board shall determine, subject to earlier termination as provided herein and in the Option Agreement (and each Incentive Option being subject to the limitations set forth in Section 4(a) of this Plan with respect to grants to 10% Owners), but in no event shall the term of any Option be more than ten years from the date of grant. No Option may be exercised following termination thereof. (b) If an Incentive Option holder's employment with the Company or a Subsidiary is terminated for any reason other than by reason of death or disability (within the meaning of Section 22(e)(3) of the Code), such holder's Incentive Option shall terminate on the earlier of (i) three (3) months from the date of such termination of employment, or (ii) the expiration date of the term of such Option. Absence on leave approved by the employer corporation shall not be considered an interruption of employment for any purpose under this Plan. (c) If an Incentive Option holder's employment with the Company or a Subsidiary is terminated by reason of such holder's disability within the meaning of Section 22(e)(3) of the Code, subject to paragraph 6(d) hereof, such holder's Incentive Option shall terminate on the earlier of (i) one (1) year from the date of such termination, or (ii) the expiration date of the term of such Option. (d) If an Incentive Option holder dies while in the employ of the Company or a Subsidiary (or within one (1) year following termination of employment due to disability within the meaning of Section 22(e)(3) of the Code), such holder's Incentive Option shall terminate on the earlier of (i) one (1) year from the date of death, or (ii) the expiration date of the term of the Option. To the extent such Incentive Option was exercisable by such holder at the date of death (or the date of termination of employment due to disability within the meaning of Section 22(e)(3) of the Code), such Option may be exercised by the legatee or legatees of such person under such person's Last Will, or by such person's personal representative or distributees, within one (1) year from the date of death but in no event subsequent to the expiration date of the Incentive Option. 7. Exercise of Options. (a) Incentive and Non-Incentive Options shall be exercisable within the times or upon the events determined by the Board as set forth in the Option Agreements. (b) An Option may not be exercised for fractional shares of the Company's Common Stock. (c) If an Option holder ceases to be an employee, director, consultant, agent, independent contractor or other person employed by or engaged in performing services for the Company and/or a Subsidiary, the Option held by such person shall be exercisable after the date of termination of employment or engagement only to the extent such Option was exercisable by such holder at the date of termination. In no event shall such option be exercisable following the expiration of its term or earlier termination. (d) The exercise of an Option shall be contingent upon receipt by the Company from the holder of such Option of a written representation that at the time of such exercise it is the Optionholder's then present intention to acquire the Option shares for investment and not with a view to the distribution or resale thereof (unless a Registration Statement covering the shares purchasable upon exercise of the Options shall have been declared effective by the Securities and Exchange Commission) and upon receipt by the Company of cash, or a check to its order, for the full purchase price of such shares. In addition, the holder of such Option must agree to refrain from selling or offering to sell any securities of the Company for such reasonable period of time after the effective date of any registration statement relating to an underwritten offering of securities of the Company, as may be requested by the managing underwriter of such underwritten offering, and approved by the Board of Directors. The Company shall be under no obligation to register the Shares with the Securities and Exchange Commission or to effect compliance with the Securities Act of 1933 or with the registration or qualification requirement of any state securities laws or stock exchange. (e) Payment for the shares of Common Stock may be made (i) in cash or by check to the order of the Company; (ii) by surrender of shares of Common Stock having a Fair Market Value equal to the exercise price of the Option; or (iii) by any combination of the foregoing where approved by the Board in its sole discretion; provided, however, in the event of payment for the shares of Common Stock by method (ii) above, the shares of Common Stock so surrendered, if originally issued to the Optionholder upon exercise of an Option(s) granted by the Company, shall have been held by the Optionholder for more than six months. (f) The holder of an Option shall have none of the rights of a shareholder with respect to the shares purchasable upon exercise of the Option until a certificate for such shares shall have been issued to the holder upon due exercise of the Option. (g) The proceeds received by the Company upon exercise of an Option shall be added to the Company's working capital and be available for general corporate purposes. 8. Non-Transferability of Incentive Options. No Incentive Option granted pursuant to this Plan shall be transferable otherwise than by will or the laws of descent or distribution and an Incentive Option may be exercised during the lifetime of the Option holder only by such Option holder. 9. No Right of Employment. Nothing in this Plan or in any Option Agreement granted hereunder shall: (a) confer upon any Option holder any right to continue in the employ of the Company or any Subsidiary or obligate the Company or any Subsidiary to continue the engagement of any Option holder; or (b) interfere in any way with the right of the Company or any such Subsidiary to terminate such Option holder's employment or engagement at any time. 10. Adjustments Upon Changes in Capitalization. If at any time after the date of grant of an Option, the Company shall by stock dividend, split-up, combination, reclassification or exchange, or through merger or consolidation or otherwise, change its shares of Common Stock into a different number or kind or class of shares or other securities or property, then the number of shares covered by such Option and the price per share thereof shall be proportionately adjusted for any such change by the Board, whose determination thereon shall be conclusive. In the event that a fraction of a share results from the foregoing adjustment, said fraction shall be eliminated and the price per share of the remaining shares subject to the Option adjusted accordingly. 11. Vesting of Rights Under Options. Nothing contained in this Plan or in any resolution adopted or to be adopted by the Board or the shareholders of the Company shall constitute the vesting of any rights under any Option. The vesting of such rights shall take place only when a written Option Agreement, substantially in the form of the Incentive Stock Option Agreement attached hereto as Exhibit A or the Non-Incentive Stock Option Agreement attached hereto as Exhibit B (with such changes to such Exhibits as may be necessary to reflect the terms and conditions of the grant in question), shall be duly executed and delivered by and on behalf of the Company and the person to whom the Option shall be granted, subject, however, in either event, to the rights granted to the Company and the Committee hereunder and to the terms and conditions of the Option Agreement. 12. Withholding Taxes. Whenever under this Plan shares are to be issued in satisfaction of the exercise of Options granted hereunder, the Company shall have the right to require the recipient to remit to the Company an amount sufficient to satisfy federal, state and local withholding tax requirements prior to the delivery of any certificate or certificates for such shares. 13. Restrictions on Shares. At the discretion of the Board, the Company may reserve to itself or its assignee(s) in the Option Agreement (a) a right of first refusal to purchase any shares that an Optionholder (or a subsequent transferee) may propose to transfer to a third party and (b) a right to repurchase any or all shares held by an Optionholder upon the Optionee's termination of employment or service with the Company or a subsidiary for any reason within a specified time as determined by the Board at the time of grant at (i) the Optionholder's original purchase price, (ii) the Fair Market Value of such shares as determined by the Board in good faith, or (iii) a price determined by a provision set forth in the Option Agreement. 14. Termination and Amendment. The Board may at any time terminate, amend or modify this Plan in any respect (including, but not limited to, any form of grant, agreement or instrument to be executed pursuant to this Plan); provided, however, that shareholder approval shall be required to be obtained by the Company if required to comply with the Incentive Option provisions or Section 162(m) of the Code, or the listed company requirements of The Nasdaq Stock Market or of a national securities exchange on which the shares of Common Stock are traded, or other applicable provisions of state or federal law or self-regulatory agencies; provided, further, that no termination, amendment or modification of this Plan may materially adversely affect the rights of a holder of an Option previously granted under this Plan without the written consent of such Optionholder. 15. Term of Plan. This Plan was originally adopted by the Board of Directors on October 1, 1996 and approved by the shareholders of the Company on October 1, 1996. No Option shall be granted pursuant to this Plan on or after September 30 , 2006, but Options theretofore granted may extend beyond that date and the terms of this Plan shall continue to apply to such Options and to any shares of Common Stock acquired upon exercise thereof. 16. Applicable Law. The validity, interpretation and enforcement of this Plan shall be governed in all respects by the laws of the State of New York and the United States of America. 17. Issuance of Shares. The Shares, when issued and paid for pursuant to the Options granted hereunder, shall be fully paid and non-assessable Shares. 18. Partial Invalidity. The invalidity or illegality of any provision herein shall not be deemed to affect the validity of any other provision.
