EXHIBIT 10(a1) INTERLEAF, INC. 1994 EMPLOYEE STOCK OPTION PLAN Adopted by Board of Directors on July 14, 1994 and Amended on May 3, 1996 1. PURPOSE. The purpose of this plan (the "Plan") is to secure for Interleaf, Inc. (the "Company") and its shareholders the benefits arising from capital stock ownership by employees, consultants or advisors to the Company (but specifically excluding officers and directors) and its parent and subsidiary corporations who are expected to contribute to the Company's future growth and success. Except where the context otherwise requires, the term "Company" shall include the parent and all present and future subsidiaries of the Company as defined in Sections 425(e) and 425(f) of the Internal Revenue Code of 1986, as amended or replaced from time to time (the "Code"). 2. TYPE OF OPTIONS AND ADMINISTRATION. (a) TYPES OF OPTIONS. Options granted pursuant to the Plan shall be authorized by action of the Board of Directors of the Company (or a Committee designated by the Board of Directors) and shall be non-statutory options which are not intended to meet the requirements of Section 422 of the Code. (b) ADMINISTRATION. The Plan will be administered by the Board of Directors of the Company, whose construction and interpretation of the terms and provisions of the Plan shall be final and conclusive. The Board of Directors may in its sole discretion grant options to purchase shares of the Company's Common Stock ("Common Stock") and issue shares upon exercise of such options as provided in the Plan. The Board shall have authority, subject to the express provisions of the Plan, to construe the respective option agreements and the Plan, to prescribe, amend and rescind rules and regulations relating to the Plan, to determine the terms and provisions of the respective option agreements, which need not be identical, and to make all other determinations in the judgment of the Board of Directors necessary or desirable for the administration of the Plan. The Board of Directors may correct any defect or supply any omission or reconcile any inconsistency in the Plan or in any option agreement in the manner and to the extent it shall deem expedient to carry the Plan into effect and it shall be the sole and final judge of such expediency. No director shall be liable for any action or determination made in good faith. The Board of Directors may, to the full extent permitted by or consistent with applicable laws or regulations, delegate any or all of its powers under the Plan to a committee (the "Committee") appointed by the Board of Directors, and if the Committee is so appointed all references to the Board of Directors in the Plan shall mean and relate to such Committee. 3. ELIGIBILITY. (a) GENERAL. Options shall be granted to persons who are, at the time of grant, employees, consultants or advisors to, the Company, but who are not officers or directors of Interleaf, Inc. at such time. A person who has been granted an option may, if he or she is otherwise eligible, be granted an additional option or options if the Board of Directors shall so determine. 4. STOCK SUBJECT TO PLAN. Subject to adjustment as provided in Section 14 below, the maximum number of shares of Common Stock of the Company which may be issued and sold under the Plan is 1,500,000 shares. If an option granted under the Plan shall expire or terminate for any reason without having been exercised in full, the unpurchased shares subject to such option shall again be available for subsequent option grants under the Plan. If shares issued upon exercise of an option under the Plan are tendered to the Company in payment of the exercise price of an option granted under the Plan, such tendered shares shall again be available for subsequent option grants under the Plan. 5. FORMS OF OPTION AGREEMENTS. As a condition to the grant of an option under the Plan, each recipient of an option shall execute an option agreement in such form not inconsistent with the Plan as may be approved by the Board of Directors. Such option agreements may differ among recipients. 6. PURCHASE PRICE. (a) GENERAL. The purchase price per share of stock deliverable upon the exercise of an option shall be determined by the Board of Directors, at the time of grant of such option. (b) PAYMENT OF PURCHASE PRICE. Options granted under the Plan may provide for the payment of the exercise price by delivery of cash or a check to the order of the Company in an amount equal to the exercise price of such options, or, to the extent provided in the applicable option agreement, (i) by delivery to the Company of shares of Common Stock of the Company already owned by the optionee having a fair market value equal in amount to the exercise price of the options being exercised, (ii) by any other means which the Board of Directors determines are consistent with the purpose of the Plan and with applicable laws and regulations (including, without limitation, Regulation T promulgated by the Federal Reserve Board) or (iii) by any combination of such methods of payment. The fair market value of any shares of the Company's Common Stock or other non-cash consideration which may be delivered upon exercise of an option shall be determined in such manner as may be prescribed by the Board of Directors. 2 7. OPTION PERIOD. Each option and all rights thereunder shall expire on such date as shall be set forth in the applicable option agreement. 8. EXERCISE OF OPTIONS. Each option granted under the Plan shall be exercisable either in full or in installments at such time or times and during such period as shall be set forth in the agreement evidencing such option, subject to the provisions of the Plan. 9. NONTRANSFERABILITY OF OPTIONS. Options granted hereunder shall not be assignable or transferable by the person to whom it is granted, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the life of the optionee, shall be exercisable only by the optionee. 10. EFFECT OF TERMINATION OF EMPLOYMENT OR OTHER RELATIONSHIP. The Board of Directors shall determine the period of time during which an optionee may exercise an option following (i) the termination of the optionee's employment or other relationship with the Company or (ii) the death or disability of the optionee. Such periods shall be set forth in the agreement evidencing such option. 11. ADDITIONAL PROVISIONS. (a) ADDITIONAL OPTION PROVISIONS. The Board of Directors may, in its sole discretion, include additional provisions in any option granted under the Plan, including without limitation restrictions on transfer, repurchase rights, commitments to pay cash bonuses, to make, arrange for or guaranty loans or to transfer other property to optionees upon exercise of options, or such other provisions as shall be determined by the Board of Directors; provided that such additional provisions shall not be inconsistent with any other term or condition of the Plan. (b) ACCELERATION, EXTENSION, ETC. The Board of Directors may, in its sole discretion, (i) accelerate the date or dates on which all or any particular option or options granted under the Plan may be exercised or (ii) extend the dates during which all or any particular option or options granted under the Plan may be exercised. 12. GENERAL RESTRICTIONS. (a) INVESTMENT REPRESENTATIONS. The Company may require any person to whom an option is granted, as a condition of exercising such option, to give written assurances in substance and form satisfactory to the Company to the effect that such person is acquiring the Common Stock subject to the option for his or her own account for investment and not with any present intention of selling or otherwise distributing the same, and to such other effects as the Company deems necessary or appropriate in order to comply with federal and applicable state securities laws, or with covenants or 3 representations made by the Company in connection with any public offering of its Common Stock. (b) COMPLIANCE WITH SECURITIES LAWS. Each option shall be subject to the requirement that if, at any time, counsel to the Company shall determine that the listing, registration or qualification of the shares subject to such option upon any securities exchange or under any state or federal law, or the consent or approval of any governmental or regulatory body, or that the disclosure of non-public information or the satisfaction of any other condition is necessary as a condition of, or in connection with, the issuance or purchase of shares thereunder, such option may not be exercised, in whole or in part, unless such listing, registration, qualification, consent or approval, or satisfaction of such condition shall have been effected or obtained on conditions acceptable to the Board of Directors. Nothing herein shall be deemed to require the Company to apply for or to obtain such listing, registration or qualification, or to satisfy such condition. 13. RIGHTS AS A SHAREHOLDER. The holder of an option shall have no rights as a shareholder with respect to any shares covered by the option (including, without limitation, any rights to receive dividends or non-cash distributions with respect to such shares) until the date of issue of a stock certificate to him or her for such shares. No adjustment shall be made for dividends or other rights for which the record date is prior to the date such stock certificate is issued. 14. ADJUSTMENT PROVISIONS FOR RECAPITALIZATIONS AND RELATED TRANSACTIONS. (a) GENERAL. If, through or as a result of any merger, consolidation, sale of all or substantially all of the assets of the Company, reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar transaction, (i) the outstanding shares of Common Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or (ii) additional shares or new or different shares or other securities of the Company or other non-cash assets are distributed with respect to such shares of Common Stock or other securities, an appropriate and proportionate adjustment may be made in (x) the maximum number and kind of shares reserved for issuance under the Plan, (y) the number and kind of shares or other securities subject to then outstanding options under the Plan, and (z) the price for each share subject to any then outstanding options under the Plan, without changing the aggregate purchase price as to which such options remain exercisable. (b) BOARD AUTHORITY TO MAKE ADJUSTMENTS. Any adjustments under this Section 14 will be made by the Board of Directors, whose determination as to what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive. No fractional shares will be issued under the Plan on account of any such adjustments. 4 15. MERGER, CONSOLIDATION, ASSET SALE, LIQUIDATION, ETC. (a) GENERAL. In the event of a consolidation or merger or sale of all or substantially all of the assets of the Company in which outstanding shares of Common Stock are exchanged for securities, cash or other property of any other corporation or business entity or in the event of a liquidation of the Company, the Board of Directors of the Company, or the board of directors of any corporation assuming the obligations of the Company, may, in its discretion, take any one or more of the following actions, as to outstanding options: (i) provide that such options shall be assumed, or equivalent options shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), (ii) upon written notice to the optionees, provide that all unexercised options will terminate immediately prior to the consummation of such transaction unless exercised by the optionee within a specified period following the date of such notice, (iii) in the event of a merger under the terms of which holders of the Common Stock of the Company will receive upon consummation thereof a cash payment for each share surrendered in the merger (the "Merger Price"), make or provide for a cash payment to the optionees equal to the difference between (A) the Merger Price times the number of shares of Common Stock subject to such outstanding options (to the extent then exercisable at prices not in excess of the Merger Price) and (B) the aggregate exercise price of all such outstanding options in exchange for the termination of such options, and (iv) provide that all or any outstanding options shall become exercisable in full immediately prior to such event. (b) SUBSTITUTE OPTIONS. The Company may grant options under the Plan in substitution for options held by employees of another corporation who become employees of the Company, or a subsidiary of the Company, as the result of a merger or consolidation of the employing corporation with the Company or a subsidiary of the Company, or as a result of the acquisition by the Company, or one of its subsidiaries, of property or stock of the employing corporation. The Company may direct that substitute options be granted on such terms and conditions as the Board of Directors considers appropriate in the circumstances. 16. CHANGE IN CONTROL. Notwithstanding any other provision of the Plan and except as otherwise provided in the relevant option agreement, in the event of a "Change in Control of the Company" (as defined below), the exercise dates of all options then outstanding shall be accelerated in full and any restrictions on exercising outstanding options issued pursuant to the Plan prior to any given date shall terminate. For purposes of the Plan, a "Change in Control of the Company" shall occur or be deemed to have occurred only if (i) any "person," as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") (other than the Company, any trustee of other fiduciary holding securities under an employee benefit plan of the Company, or any corporation owned directly or indirectly by the stockholders of the Company in substantially the same proportion as their ownership of stock of the 5 Company), is or becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 25% or more of the combined voting power of the Company's then outstanding securities; (ii) during any period of two consecutive years ending during the term of the Plan (not including any period prior to the adoption of the Plan), individuals who at the beginning of such period constitute the Board of Directors of the Company, and any new director (other than a director designated by a person who has entered into an agreement with the Company to effect any transaction described in clause (i), (iii), or (iv) of this Section 16) whose election by the Board of Directors or nomination for election by the Company's shareholders was approved by a vote of at least two-thirds of the directors then still in office who were either directors at the beginning of the period or whose election or whose nomination for election was previously so approved (collectively, the "Disinterested Directors"), cease for any reason to constitute a majority of the Board of Directors; (iii) the shareholders of the Company approve a merger or consolidation of the Company with any other corporation, other than (A) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than 80% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation or (B) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no "person" (as hereinabove defined) acquires more than 25% of the combined voting power of the Company's then outstanding securities; or (iv) the shareholders of the Company approve a plan of complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company's assets. 17. NO SPECIAL EMPLOYMENT RIGHTS. Nothing contained in the Plan or in any option shall confer upon any optionee any right with respect to the continuation of his or her employment by the Company or interfere in any way with the right of the Company at any time to terminate such employment or to increase or decrease the compensation of the optionee. 18. OTHER EMPLOYEE BENEFITS. The amount of any compensation deemed to be received by an employee as a result of the exercise of an option or the sale of shares received upon such exercise will not constitute compensation with respect to which any other employee benefits of such employee are determined, including, without limitation, benefits under any bonus, pension, profit-sharing, life insurance or salary continuation plan, except as otherwise specifically determined by the Board of Directors. 6 19. AMENDMENT OF THE PLAN. (a) The Board of Directors may at any time, and from time to time, modify or amend the Plan in any respect. (b) The termination or any modification or amendment of the Plan shall not, without the consent of an optionee, affect his or her rights under an option previously granted to him or her. With the consent of the optionee affected, the Board of Directors may amend outstanding option agreements in a manner not inconsistent with the Plan. 20. WITHHOLDING. The Company shall have the right to deduct from payments of any kind otherwise due to the optionee any federal, state or local taxes of any kind required by law to be withheld with respect to any shares issued upon exercise of options under the Plan. Subject to the prior approval of the Company, which may be withheld by the Company in its sole discretion, the optionee may elect to satisfy such obligations, in whole or in part, (i) by causing the Company to withhold shares of Common Stock otherwise issuable pursuant to the exercise of an option or (ii) by delivering to the Company shares of Common Stock already owned by the optionee. The shares so delivered or withheld shall have a fair market value equal to such withholding obligation. The fair market value of the shares used to satisfy such withholding obligation shall be determined by the Company as of the date that the amount of tax to be withheld is to be determined. An optionee who has made an election pursuant to this Section 20 may only satisfy his or her withholding obligation with shares of Common Stock which are not subject to any repurchase, forfeiture, unfulfilled vesting or other similar requirements. 21. CANCELLATION AND NEW GRANT OF OPTIONS, ETC. The Board of Directors shall have the authority to effect, at any time and from time to time, with the consent of the affected optionees, (i) the cancellation of any or all outstanding options under the Plan and the grant in substitution therefor of new options under the Plan covering the same or different numbers of shares of Common Stock and having an option exercise price per share which may be lower or higher than the exercise price per share of the cancelled options or (ii) the amendment of the terms of any and all outstanding options under the Plan to provide an option exercise price per share which is higher or lower than the then-current exercise price per share of such outstanding options. 22. EFFECTIVE DATE AND DURATION OF THE PLAN. (a) EFFECTIVE DATE. The Plan shall become effective when adopted by the Board of Directors. Unless otherwise provided, amendments to the Plan shall become effective when adopted by the Board of Directors. Options may be granted under the Plan at any time after the effective date and before the date fixed for termination of the Plan. 7 (b) TERMINATION. Unless sooner terminated in accordance with Section 16, the Plan shall terminate on the date on which all shares available for issuance under the Plan shall have been issued pursuant to the exercise of options granted under the Plan. 23. PROVISION FOR FOREIGN PARTICIPANTS. The Board of Directors may, without amending the Plan, modify awards or options granted to participants who are foreign nationals or employed outside the United States to recognize differences in laws, rules, regulations or customs of such foreign jurisdictions with respect to tax, securities, currency, employee benefit or other matters. Adopted by the Board of Directors on July 14, 1994 and amended on May 3, 1996. 8
