Stock Subject to the Plan; Grant Limitations. 4.1 The maximum number of Shares that may be made the subject of Options granted under the Plan is 250,000. The maximum number of Shares that may be the subject of Options granted to any Eligible Individual during any three (3) consecutive calendar year period may not exceed 100,000 Shares. Upon a Change in Capitalization, the maximum number of Shares referred to in the first two sentences of this Section 4.1 shall be adjusted in number and kind pursuant to Section 7. The Company shall reserve for the purposes of the Plan, out of its authorized but unissued Shares or out of Shares held in the Company's treasury, or partly out of each, such number of Shares as shall be determined by the Board. 4.2 Upon the granting of an Option, the number of Shares available under Section 4.1 for the granting of further Options shall be reduced by the number of Shares in respect of which the Option is granted; provided, however, that if any Option is exercised by tendering Shares, either actually or by attestation, to the Company as full or partial payment of the exercise price, the maximum number of Shares available under Section 4.1 shall be increased by the number of Shares so tendered. 10(l)-4 4.3 Whenever any outstanding Option or portion thereof expires, is canceled, is settled in cash (including the settlement of tax withholding obligations using Shares) or is otherwise terminated for any reason without having been exercised or payment having been made in respect of the entire Option, the Shares allocable to the expired, canceled, settled or otherwise terminated portion of the Option may again be the subject of Options granted hereunder. 5. Option Grants for Eligible Individuals. 5.1 Authority of Committee. Subject to the provisions of the Plan, the Committee shall have full and final authority to select those Eligible Individuals who will receive Options, and the terms and conditions of the grant to such Eligible Individuals shall be set forth in an Agreement. 5.2 Exercise Price. The purchase price or the manner in which the exercise price is to be determined for Shares under each Option shall be determined by the Committee and set forth in the Agreement; provided, however, that the exercise price per Share under each Incentive Stock Option shall not be less than 100% of the Fair Market Value of a Share on the date the Option is granted (110% in the case of an Incentive Stock Option granted to a Ten-Percent Stockholder). 5.3 Maximum Duration. Options granted hereunder shall be for such term as the Committee shall determine, provided that an Incentive Stock Option shall not be exercisable after the expiration of ten (10) years from the date it is granted (five (5) years in the case of an Incentive Stock Option granted to a Ten-Percent Stockholder) and a Nonqualified Stock Option shall not be exercisable after the expiration of ten (10) years from the date it is granted; provided, however, that the Committee may provide that an Option (other than an Incentive Stock Option) may, upon the death of the Optionee, be exercised for up to one (1) year following the date of the Optionee's death even if such period extends beyond ten (10) years from the date the Option is granted. The Committee may, subsequent to the granting of any Option, extend the term thereof, but in no event shall the term as so extended exceed the maximum term provided for in the preceding sentence. 5.4 Vesting. Each Option shall become exercisable in such installments (which need not be equal) and at such times as may be designated by the Committee and set forth in the Agreement. To the extent not exercised, installments shall accumulate and be exercisable, in whole or in part, at any time after becoming exercisable, but not later than the date the Option expires. The Committee may accelerate the exercisability of any Option or portion thereof at any time. 5.5 Deferred Delivery of Option Shares. The Committee may, in its discretion, permit Optionees to elect to defer the issuance of Shares upon the exercise of one or more Nonqualified Stock Options granted pursuant to the Plan. The terms and conditions of such deferral shall be determined at the time of the grant of the Option or thereafter and shall be set forth in the Agreement evidencing the grant. 5.6 Limitations on Incentive Stock Options. To the extent that the aggregate Fair Market Value (determined as of the date of the grant) of Shares with respect to which Incentive Stock Options granted under the Plan and "incentive stock options" (within the meaning of Section 422 of the Code) granted under all other plans of the Company or its Subsidiaries (in either case determined without regard to this Section 5.6) are exercisable by an Optionee for the first time during any calendar year exceeds $100,000, such Incentive Stock Options shall be treated as Nonqualified Stock Options. In applying the limitation in the preceding sentence in the case of multiple Option grants, Options which were intended to be Incentive Stock Options shall be treated as Nonqualified Stock Options according to the order in which they were granted such that the most recently granted Options are first treated as Nonqualified Stock Options. 10(l)-5 5.7 Non-Transferability. No Option shall be transferable by the Optionee otherwise than by will or by the laws of descent and distribution or, in the case of an Option other than an Incentive Stock Option, pursuant to a domestic relations order (within the meaning of Rule 16a-12 promulgated under the Exchange Act), and an Option shall be exercisable during the lifetime of such Optionee only by the Optionee or his or her guardian or legal representative. Notwithstanding the foregoing, the Committee may set forth in the Agreement evidencing an Option (other than an Incentive Stock Option) at the time of grant or thereafter, that the Option may be transferred to a Permitted Transferee, and for purposes of the Plan, such Permitted Transferee shall be deemed to be the Optionee. The terms of an Option shall be final, binding and conclusive upon the beneficiaries, executors, administrators, heirs and successors of the Optionee. 5.8 Method of Exercise. The exercise of an Option shall be made only by a written notice delivered in person or by mail to the Secretary of the Company at the Company's principal executive office, specifying the number of Shares to be exercised and, to the extent applicable, accompanied by payment therefor and otherwise in accordance with the Agreement pursuant to which the Option was granted. The exercise price for any Shares purchased pursuant to the exercise of an Option shall be paid, as determined by the Committee in its discretion, in either of the following forms (or any combination thereof): (a) cash or (b) the transfer, either actually or by attestation, to the Company of Shares upon such terms and conditions as determined by the Committee. In addition, Options may be exercised through a registered broker-dealer pursuant to such cashless exercise procedures which are, from time to time, deemed acceptable by the Committee. Any Shares transferred to the Company (or withheld upon exercise) as payment of the exercise price under an Option shall be valued at their Fair Market Value on the day preceding the date of exercise of such Option. If requested by the Committee, the Optionee shall deliver the Agreement evidencing the Option to the Secretary of the Company who shall endorse thereon a notation of such exercise and return such Agreement to the Optionee. No fractional Shares (or cash in lieu thereof) shall be issued upon exercise of an Option and the number of Shares that may be purchased upon exercise shall be rounded to the nearest number of whole Shares. 5.9 Rights of Optionees. No Optionee shall be deemed for any purpose to be the owner of any Shares subject to any Option unless and until (a) the Option shall have been exercised pursuant to the terms thereof, (b) the Company shall have issued and delivered Shares to the Optionee, and (c) the Optionee's name shall have been entered as a stockholder of record on the books of the Company. Thereupon, the Optionee shall have full voting, dividend and other ownership rights with respect to such Shares, subject to such terms and conditions as may be set forth in the applicable Agreement. 6. Effect of a Termination of Employment. The Agreement evidencing the grant of each Option shall set forth the terms and conditions applicable to such Option upon a termination or change in the status of the employment of the Optionee by the Company or a Subsidiary or a Division (including a termination or change by reason of the sale of a Subsidiary or a Division), which shall be as the Committee may, in its discretion, determine at the time the Option is granted or thereafter. 7. Adjustments. 7.1 In the event of a Change in Capitalization, the liquidation or dissolution of the Company or a merger or consolidation of the Company, the Committee shall conclusively determine the appropriate adjustments, if any, to (i) the maximum number and class of Shares or other stock or securities with respect to which Options may be granted under the Plan, (ii) the maximum number and class of Shares or other stock or securities with respect to which Options may be granted to any Eligible Individual during any three (3) consecutive calendar year period and (iii) the number and class of Shares or other stock or securities which are subject to outstanding Options granted under the Plan and the exercise price therefor, if applicable. 10(l)-6 7.2 Any such adjustment in the Shares or other stock or securities subject to outstanding Incentive Stock Options (including any adjustments in the exercise price) shall be made in such manner as not to constitute a modification as defined by Section 424(h)(3) of the Code and only to the extent otherwise permitted by Sections 422 and 424 of the Code. 7.3 If, by reason of a Change in Capitalization, an Optionee shall be entitled to exercise an Option with respect to new, additional or different shares of stock or securities, such new, additional or different shares shall thereupon be subject to all of the conditions, restrictions and performance criteria which were applicable to the Shares subject to the Option prior to such Change in Capitalization. 8. Interpretation. 8.1 The Plan is intended to comply with Rule 16b-3 promulgated under the Exchange Act and the Committee shall interpret and administer the provisions of the Plan or any Agreement in a manner consistent therewith. Any provisions inconsistent with such rule shall be inoperative and shall not affect the validity of the Plan. 9. Termination and Amendment of the Plan or Modification of Options. 9.1 Plan Amendment or Termination. The Plan shall terminate on the day preceding the tenth anniversary of the date of its adoption by the Board and no Option may be granted thereafter. The Board may sooner terminate the Plan and the Board may at any time and from time to time amend, modify or suspend the Plan; provided, however, that: (a) no such amendment, modification, suspension or termination shall impair or adversely alter any Options theretofore granted under the Plan, except with the consent of the Optionee, nor shall any amendment, modification, suspension or termination deprive any Optionee of any Shares which he or she may have acquired through or as a result of the Plan; and (b) to the extent necessary under any applicable law, regulation or exchange requirement, no amendment shall be effective unless approved by the stockholders of the Company in accordance with applicable law, regulation or exchange requirement. 9.2 Modification of Options. No modification of an Option shall adversely alter or impair any rights or obligations under the Option without the consent of the Optionee. 10. Non-Exclusivity of the Plan. The adoption of the Plan by the Board shall not be construed as amending, modifying or rescinding any previously approved incentive arrangement or as creating any limitations on the power of the Board to adopt such other incentive arrangements as it may deem desirable, including, without limitation, the granting of stock options otherwise than under the Plan, and such arrangements may be either applicable generally or only in specific cases. 11. Limitation of Liability. 10(l)-7 As illustrative of the limitations of liability of the Company, but not intended to be exhaustive thereof, nothing in the Plan shall be construed to: (a) give any person any right to be granted an Option other than at the sole discretion of the Committee; (b) give any person any rights whatsoever with respect to Shares except as specifically provided in the Plan; (c) limit in any way the right of the Company or any Subsidiary to terminate the employment or service of any person at any time; or (d) be evidence of any agreement or understanding, expressed or implied, that the Company will employ any person at any particular rate of compensation or for any particular period of time. 12. Regulations and Other Approvals; Governing Law. 12.1 Except as to matters of federal law, the Plan and the rights of all persons claiming hereunder shall be construed and determined in accordance with the laws of the State of Delaware without giving effect to conflicts of laws principles thereof. 12.2 The obligation of the Company to sell or deliver Shares with respect to Options granted under the Plan shall be subject to all applicable laws, rules and regulations, including all applicable federal and state securities laws, and the obtaining of all such approvals by governmental agencies as may be deemed necessary or appropriate by the Committee. 12.3 The Board may make such changes as may be necessary or appropriate to comply with the rules and regulations of any government authority, or to obtain for Eligible Individuals granted Incentive Stock Options the tax benefits under the applicable provisions of the Code and regulations promulgated thereunder. 12.4 Each Option is subject to the requirement that, if at any time the Committee determines, in its discretion, that the listing, registration or qualification of Shares issuable pursuant to the Plan is required by any securities exchange or under any state or federal law, or the consent or approval of any governmental regulatory body is necessary or desirable as a condition of, or in connection with, the grant of an Option or the issuance of Shares, no Options shall be granted or payment made or Shares issued, in whole or in part, unless listing, registration, qualification, consent or approval has been effected or obtained free of any conditions as acceptable to the Committee. 12.5 Notwithstanding anything contained in the Plan or any Agreement to the contrary, in the event that the disposition of Shares acquired pursuant to the Plan is not covered by a then current registration statement under the Securities Act of 1933, as amended (the "Securities Act"), and is not otherwise exempt from such registration, such Shares shall be restricted against transfer to the extent required by the Securities Act and Rule 144 or other regulations thereunder. The Committee may require any individual receiving Shares pursuant to an Option granted under the Plan, as a condition precedent to receipt of such Shares, to represent and warrant to the Company in writing that the Shares acquired by such individual are acquired without a view to any distribution thereof and will not be sold or transferred other than pursuant to an effective registration thereof under said Act or pursuant to an exemption applicable under the Securities Act or the rules and regulations promulgated thereunder. The certificates evidencing any of such Shares shall be appropriately amended to reflect their status as restricted securities as aforesaid. 10(l)-8 13. Miscellaneous. 13.1 Multiple Agreements. The terms of each Option may differ from other Options granted under the Plan at the same time, or at some other time. The Committee may also grant more than one Option to a given Eligible Individual during the term of the Plan, either in addition to, or in substitution for, one or more Options previously granted to that Eligible Individual. 13.2 Withholding of Taxes. (a) At such times as an Optionee recognizes taxable income in connection with the receipt of Shares hereunder (a "Taxable Event"), the Optionee shall pay to the Company an amount equal to the federal, state and local income taxes and other amounts as may be required by law to be withheld by the Company in connection with the Taxable Event (the "Withholding Taxes") prior to the issuance of such Shares. The Company shall have the right to deduct from any payment of cash to an Optionee an amount equal to the Withholding Taxes in satisfaction of the obligation to pay Withholding Taxes. The Committee may provide in the Agreement, at the time of grant or at any time thereafter, that the Optionee, in satisfaction of the obligation to pay Withholding Taxes, may elect to have withheld a portion of the Shares then issuable to him or her having an aggregate Fair Market Value equal to the Withholding Taxes. (b) If an Optionee makes a disposition, within the meaning of Section 424(c) of the Code and regulations promulgated thereunder, of any Share or Shares issued to such Optionee pursuant to the exercise of an Incentive Stock Option within the two-year period commencing on the day after the date of the grant or within the one-year period commencing on the day after the date of transfer of such Share or Shares to the Optionee pursuant to such exercise, the Optionee shall, within ten (10) days of such disposition, notify the Company thereof, by delivery of written notice to the Company at its principal executive office. 13.3 Stockholder Approval. This Plan and all Options granted under the Plan are subject to the approval of the Plan by the affirmative vote of the holders of a majority of the common stock of the Company present or represented and entitled to vote at a meeting of stockholders duly held in accordance with the applicable laws of the State of Delaware (or by written consent of the holders of a majority of the outstanding common stock of the Company) within twelve (12) months of the adoption of the Plan by the Board. 10(l)-9
