1 EXHIBIT 99.1 FASTCOMM COMMUNICATIONS CORPORATION 1999 STOCK OPTION PLAN ARTICLE ONE GENERAL PROVISIONS I. PURPOSE OF THE PLAN This 1999 Stock Option Plan is intended to promote the interests of FastComm Communications Corporation, a Virginia corporation, by providing eligible persons with the opportunity to acquire a proprietary interest, or otherwise increase their proprietary interest, in the Corporation as an incentive for them to remain in the service of the Corporation. This Plan shall supplement the authorized share reserve under the Corporation's 1992 Qualified and Non-Qualified Stock Option Plans (the "1992 Plans"), and share issuances under this Plan shall not reduce or otherwise affect the number of shares of the Corporation's common stock available for issuance under the 1992 Plans. In addition, share issuances under the 1992 Stock Plans shall not reduce or otherwise affect the number of shares of the Corporation's common stock available for issuance under this Plan. Capitalized terms shall have the meanings assigned to such terms in the attached Appendix. II. STRUCTURE OF THE PLAN A. The Plan shall be divided into three separate equity programs: (i) the Discretionary Option Grant Program under which eligible persons may, at the discretion of the Plan Administrator, be granted options to purchase shares of Common Stock, (ii) the Stock Issuance Program under which eligible persons may, at the discretion of the Plan Administrator, be issued shares of Common Stock directly, either through the immediate purchase of such shares or as a bonus for services rendered the Corporation (or any Parent or Subsidiary), and (iii) the Automatic Option Grant Program under which Eligible Directors shall automatically receive option grants at periodic intervals to purchase shares of Common Stock. II-12 2 B. The provisions of Articles One and Five shall apply to all equity programs under the Plan and shall accordingly govern the interests of all persons under the Plan. III. ADMINISTRATION OF THE PLAN A. The Primary Committee shall have sole and exclusive authority to administer the Discretionary Option Grant and Stock Issuance Programs with respect to all Section 16 Insiders. Administration of the Discretionary Option Grant and Stock Issuance Programs with respect to all other persons eligible to participate in those programs may, at the Board's discretion, be vested in the Primary Committee or a Secondary Committee, or the Board may retain the power to administer those programs with respect to all such persons. B. Members of the Primary Committee or any Secondary Committee shall serve for such period of time as the Board may determine and may be removed by the Board at any time. The Board may also at any time terminate the functions of any Secondary Committee and reassume all powers and authority previously delegated to such committee. C. Each Plan Administrator shall, within the scope of its administrative functions under the Plan, have full power and authority (subject to the provisions of the Plan) to establish such rules and regulations as it may deem appropriate for proper administration of the Discretionary Option Grant and Stock Issuance Programs and to make such determinations under, and issue such interpretations of, the provisions of such programs and any outstanding options or stock issuances thereunder as it may deem necessary or advisable. Decisions of the Plan Administrator within the scope of its administrative functions under the Plan shall be final and binding on all parties who have an interest in the Discretionary Option Grant or Stock Issuance Program under its jurisdiction or any option or stock issuance thereunder. D. Service on the Primary Committee or the Secondary Committee shall constitute service as a Board member, and members of each such committee shall accordingly be entitled to full indemnification and reimbursement as Board members for their service on such committee. No member of the Primary Committee or the Secondary Committee shall be liable for any act or omission made in good faith with respect to the Plan or any option grants or stock issuances under the Plan. E. Administration of the Automatic Option Grant Program shall be self-executing in accordance with the terms of that program, and no Plan Administrator shall exercise any discretionary functions with respect to option grants made thereunder. IV. ELIGIBILITY A. The persons eligible to participate in the Discretionary Option Grant and Stock Issuance programs are as follows: II-13 3 (i) Employees, (ii) non-employee members of the Board or the board of directors of any Parent or subsidiary, and (iii) consultants and other independent advisors who provide services to the Corporation (or any Parent or Subsidiary). B. Each Plan Administrator shall, within the scope of its administrative jurisdiction under the Plan, have full authority (subject to the provisions of the Plan) to determine, (i) with respect to the option grants under the Discretionary Option Grant Program, which eligible persons are to receive option grants, the time or times when such option grants are to be made, the number of shares to be covered by each such grant, the status of the granted option as either an Incentive Option or a Non-Statutory Option, the time or times when each option is to become exercisable, the vesting schedule (if any) applicable to the option shares and the maximum term for which the option is to remain outstanding and (ii) with respect to stock issuances under the Stock Issuance Program, which eligible persons are to receive stock issuances, the time or times when such issuances are to be made, the number of shares to be issued to each participant, the vesting schedule (if any) applicable to the issued shares and the consideration to be paid for such shares. C. The Plan Administrator shall have the absolute discretion either to grant options in accordance with the Discretionary Option Grant Program or to effect stock issuances in accordance with the Stock Issuance Program. D. The individuals eligible to participate in the Automatic Option Grant Program shall be limited to (i) those individuals who are first elected or appointed as non-employee Board members after the Effective Date, whether through appointment by the Board or election by the Corporation's shareholders, and (ii) those individuals who continue to serve as non-employee Board members after one or more Annual Stockholders Meetings, beginning with the 1999 Annual Meeting. A non-employee Board member who has previously been in the employ of the Corporation (or any Parent or Subsidiary) shall not be eligible to receive an option grant under the Automatic Option Grant Program at the time he or she first becomes a non-employee Board member, but shall be eligible to receive periodic option grants under the Automatic Option Grant Program while he or she continues to serve as a non-employee Board member who is, directly or indirectly, a 5% Stockholder or who is otherwise affiliated with, or a representative of, a 5% Stockholder be eligible to receive any option grants under the Automatic Option Grant Program. V. STOCK SUBJECT TO THE PLAN A. The stock issuable under the Plan shall be shares of authorized but unissued or reacquired Common Stock, including shares repurchased by the Corporation on the open market. The maximum number of shares of Common Stock reserved for issuance over the term of the Plan shall not exceed 1,500,000 shares. Such share reserve II-14 4 shall be in addition to the shares of Common Stock reserved for issuance under the 1992 Plans and share issuances under the 1992 Plans shall have no effect upon the number of shares of Common Stock which remain available issuance under this Plan. B. Shares of Common Stock subject to outstanding options under this Plan shall be available for subsequent issuance under the Plan to the extent those options expire or terminate for any reason prior to exercise in full. Unvested shares issued under the Plan and subsequently cancelled or repurchased by the Corporation, at the original issue price paid per share, pursuant to the Corporation's repurchase rights under the Plan, shall be added back to the number of shares of Common Stock reserved for issuance under the Plan and shall accordingly be available for reissuance through one or more subsequent option grants or direct stock issuances under the Plan. However, should the exercise price of an option under the Plan be paid with shares of Common Stock or should shares of Common Stock otherwise issuable under the Plan be withheld by the Corporation in satisfaction of the withholding taxes incurred in connection with the exercise of an option or the vesting of a stock issuance under the Plan, then the number of shares of Common Stock available for issuance under the Plan shall be reduced by the gross number of shares for which the option is exercised or which vest under the stock issuance, and not by the net number of shares of Common Stock issued to the holder or such option or stock issuance. C. Should any change be made to the Common Stock by reason of any stock split, stock dividend, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation's receipt of consideration, appropriate adjustments shall be made to (i) the maximum number and/or class of securities issuable under the Plan, (ii) the number and/or class of securities for which any one person may be granted stock options, separately exercisable stock appreciation rights and direct stock issuances under this Plan per calendar year, (iii) the number and/or class of securities for which automatic option grants are to be subsequently made per Eligible Director under the Automatic Option Grant Program and (iv) the number and/or class of securities and the exercise price per share in effect under each outstanding option in order to prevent the dilution or enlargement of benefits thereunder. The adjustments determined by the Plan Administrator shall be final, binding and conclusive. II-15 5 ARTICLE TWO DISCRETIONARY OPTION GRANT PROGRAM I. OPTION TERMS Each option shall be evidenced by one or more documents in the form approved by the Plan Administrator, provided, however, that each such document shall comply with the terms specified below. Each document evidencing an Incentive Option shall, in addition, be subject to the provisions of the Plan applicable to such options. A. Exercise Price 1. The exercise price per share shall be fixed by the Plan Administrator but shall not be less than eighty-five percent (85%) of the Fair Market Value per share of Common Stock on the option grant date. 2. The exercise price shall become immediately due upon exercise of the option and shall, subject to the provisions of Section I of Article Five and the documents evidencing the option, be payable in one or more of the forms specified below: (i) cash or check made payable to the Corporation, (ii) shares of Common Stock held for the requisite period necessary to avoid a charge to the Corporation's earnings for financial reporting purposes and valued at Fair Market Value on the Exercise Date, or (iii) to the extent the option is exercised for vested shares, through a special sale and remittance procedure pursuant to which the Optionee shall concurrently provide irrevocable instructions to (a) a Corporation-designated brokerage firm to effect the immediate sale of the purchased shares and remit to the Corporation, out of the sale proceeds available on the settlement date, sufficient funds to cover the aggregate exercise price payable for the purchased shares plus all applicable Federal, state and local income and employment taxes required to be withheld by the Corporation by reason of such exercise and (b) the Corporation to deliver the certificates for the purchased shares directly to such brokerage firm in order to complete the sale transaction. Except to the extent such sale and remittance procedure is utilized, payment of the exercise price for the purchased shares must be made on the Exercise Date. II-16 6 B. Exercise and Term of Options Each option shall be exercisable at such time or times, during such period and for such number of shares as shall be determined by the Plan Administrator and set forth in the documents evidencing the option. However, no option shall have a term in excess of ten (10) years measured from the option grant date. C. Effect of Termination of Service 1. The following provisions shall govern the exercise of any options held by the Optionee at the time of cessation of Service or death: (i) Any option outstanding at the time of the Optionee's cessation of Service for any reason shall remain exercisable for such period of time thereafter as shall be determined by the Plan Administrator and set forth in the documents evidencing the option, but no such option shall be exercisable after the expiration of the option term. (ii) Any option exercisable in whole or in part by the Optionee at the time of death may be subsequently exercised by the personal representative of the Optionee's estate or by the person or persons to whom the option is transferred pursuant to the Optionee's will or in accordance with the laws of descent and distribution. (iii) During the applicable post-Service exercise period, the option may not be exercised in the aggregate for more than the number of vested shares for which the option is exercisable on the date of the Optionee's cessation of Service. Upon the expiration of the applicable exercise period or (if earlier) upon the expiration of the option term, the option shall terminate and cease to be outstanding for any vested shares for which the option has not been exercised. However, the option shall, immediately upon the Optionee's cessation of Service, terminate and cease to be outstanding with respect to any shares in which the Optionee is not vested on the date of such cessation of Service. (iv) Should the Optionee's Service be terminated for Misconduct, then all outstanding options held by the Optionee shall terminate immediately and cease to be outstanding. 2. The Plan Administrator shall have the discretion, exercisable either at the time an option is granted or at any time while the option remains outstanding, to: II-17 7 (i) extend the period of time for which the option is to remain exercisable following the Optionee's cessation of Service from the period otherwise in effect for that option to such greater period of time as the Plan Administrator shall deem appropriate, but in no event beyond the expiration of the option term, and/or (ii) permit the option to be exercised, during the applicable post-Service exercise period, not only with respect to the number of vested shares of Common Stock for which such option is exercisable at the time of the Optionee's cessation of Service but also with respect to one or more additional installments in which the Optionee would have vested under the option had the Optionee continued in Service. D. Shareholder Rights The holder of an option shall have no shareholder rights with respect to the shares subject to the option until such person shall have exercised the option, paid the exercise price and become a holder of records of the purchased shares. E. Repurchase Rights The Plan Administrator shall have the discretion to grant options which are exercisable for unvested shares of Common Stock. Should the Optionee cease Service while holding such unvested shares, the Corporation shall have the right to repurchase, at the exercise price paid per share, any or all of those unvested shares. The terms upon which such repurchase right shall be exercisable (including the period and procedure for exercise and the appropriate vesting schedule for the purchased shares) shall be established by the Plan Administrator and set forth in the document evidencing such repurchase right. F. Limited Transferability of Options During the lifetime of the Optionee, Incentive Options shall be exercisable only by the Optionee and shall not be assignable or transferable other than by will or by the laws of descent and distribution following the Optionee's death. Non-Statutory Options shall be subject to the same transfer restrictions, except that a Non-Statutory Option may, in connection with the Optionee's estate plan, be assigned in whole or in part during the Optionee's lifetime to one or more members of the Optionee's immediate family or to a trust established exclusively for one or more such family members. The assigned portion may only be exercised by the person or persons who acquire a proprietary interest in the option pursuant to the assignment. The terms applicable to the assigned portion shall be the same as those in effect for the option immediately prior to such assignment and shall be set forth in such documents issued to the assignee as the Plan Administrator may deem appropriate. II-18 8 II. INCENTIVE OPTIONS The terms specified below shall be applicable to all Incentive Options. Except as modified by the provisions of this Section II, all the provisions of Articles One, Two and Five shall be applicable to Incentive Options. Options which are specifically designated as Non-Statutory Options when issued under the Plan shall not be subject to the terms of this Section II. A. Eligibility Incentive Options may only be granted to Employees. B. Exercise price The exercise price per share shall not be less than one hundred percent (100%) of the Fair Market Value per share of Common Stock on the option grant date. C. Dollar Limitation The aggregate Fair Market Value of the shares of Common Stock (determined as of the respective date or dates of grant) for which one or more options granted to any Employee under the Plan (or any other option plan of the Corporation or any Parent or Subsidiary) may for the first time become exercisable as Incentive Options during any one (1) calendar year shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the extent the Employee holds two (2) or more such options which become exercisable for the first time in the same calendar year, the foregoing limitation on the exercisability of such options as Incentive Options shall be applied on the basis of the order in which such options are granted. D. 10% Stockholder If any Employee to whom an Incentive Option is granted is a 10% Stockholder, then the exercise price per share shall not be less than one hundred ten percent (110%) of the Fair Market Value per share of Common Stock on the option grant date, and the option term shall not exceed five (5) years measured from the option grant date. III. CORPORATE TRANSACTION/CHANGE IN CONTROL A. In the event of any Corporation Transaction, each outstanding option shall automatically accelerate so that each such option shall, immediately prior to the effective date of the Corporate Transaction, become fully exercisable for any or all of those shares as fully-vested shares of Common Stock. B. All outstanding repurchase rights shall terminate automatically, and the shares of Common Stock subject to those terminated rights shall immediately vest in full, II-19 9 in the event of any Corporate Transaction. C. Immediately following the consummation of the Corporate Transaction, all outstanding options shall terminate and cease to be outstanding, except to the extent covered by Section A or B above. D. The Plan Administrator shall have the discretion, exercisable either at the time the option is granted or at any time while the option remains outstanding, to provide for the automatic acceleration of one or more outstanding options (and the automatic termination of one or more outstanding repurchase rights with the immediate vesting of the shares of Common Stock subject to those rights) upon the Involuntary Termination of the Optionee's Service within a specified period (not to exceed eighteen (18) months) following the effective date of a Change in Control. Any options so accelerated shall remain fully exercisable until the expiration or sooner termination of the option term. E. The portion of any Incentive Option accelerated in connection with a Corporate Transaction or Change in Control shall remain exercisable as an Incentive Option only to the extent the applicable One Hundred Thousand Dollar limitation is not exceeded. To the extent such dollar limitation is exceeded, the accelerated portion of such option shall be exercisable as a Non-Statutory Option under the Federal tax laws. F. The grant of options under the Discretionary Option Grant Program shall in no way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. IV. CANCELLATION AND REGRANT OF OPTIONS The Plan Administrator shall have the authority to effect, at any time and from time to time, with the consent of the affected option holders, the cancellation of any or all outstanding options under the Discretionary Option Grant Program and to grant in substitution new options covering the same or different number of shares of Common Stock but with an exercise price per share based on the Fair Market Value per share of Common Stock on the new option grant date. V. STOCK APPRECIATION RIGHTS A. The Plan Administrator shall have full power and authority to grant to selected Optionees tandem stock appreciation rights and/or limited stock appreciation rights. B. The following terms shall govern the grant and exercise of tandem stock appreciation rights: (i) One or more Optionees may be granted the right, exercisable upon such terms as the Plan Administrator may establish, to elect between the exercise of the underlying option for shares of Common Stock and the II-20 10 surrender of that option in exchange for a distribution from the Corporation in an amount equal to the excess of (a) the Fair Market Value (on the option surrender date) of the number of shares in which the Optionee is at the time vested under the surrendered option (or surrendered portion thereof) over (b) the aggregate exercise price payable for such shares. (ii) No such option surrender shall be effective unless it is approved by the Plan Administrator, either at the time of the option surrender or at any earlier time. If the surrender is so approved, then the distribution to which the Optionee shall be entitled may be made in shares of Common Stock valued at Fair Market Value on the option surrender date, in cash, or partly in shares and partly in cash, as the Plan Administrator shall in its sole discretion deem appropriate. (iii) If the surrender of an option is rejected by the Plan Administrator, then the Optionee shall retain whatever rights the Optionee had under the surrender option (or surrendered portion thereof) on the option surrender date and may exercise such rights at any time prior to the later of (a) five (5) business days after the receipt of rejection notice or (b) the last day on which the option is otherwise exercisable in accordance with the terms of the documents evidencing such option, but in no event may such rights be exercised more than ten (10) years after the option grant date. C. The following terms shall govern the grant and exercise of limited stock appreciation rights: (i) One or more Section 16 Insiders may be granted limited stock appreciation rights with respect to their outstanding options. (ii) Upon the occurrence of a Hostile Take-Over, each such individual holding one or more options with such a limited stock appreciation right shall have the unconditional right (exercisable for a thirty (30) -day period following such Hostile Take-Over) to surrender each such option to the Corporation, to the extent the option is at the time exercisable for vested shares of Common Stock. In return for the surrendered option, the Optionee shall receive a cash distribution from the Corporation in an amount equal to the excess of (A) the Take-over price of the shares of Common Stock which are at the time vested under each surrendered option (or surrendered portion thereof) over (B) the aggregate exercise price payable for such shares. Such cash distribution shall be paid within five (5) days following the option surrender date. (iii) The grant of such limited stock appreciation right shall automatically constitute the pre-approval by the Plan Administrator of the any subsequent exercise of that right in accordance with the terms of this II-21 11 Paragraph C. Accordingly, no further approval of the Plan Administrator or the Board shall be required at the time of the actual surrender of such option and the cash distribution to which the optionee shall thereupon become entitled. (iv) The balance of the option (if any) shall continue in full force and effect in accordance with the documents evidencing such option. II-22 12 ARTICLE THREE STOCK ISSUANCE PROGRAM I. STOCK ISSUANCE TERMS Shares of Common Stock may be issued under the Stock Issuance Program through direct and immediate issuances without any intervening option grants. Each such stock issuance shall be evidenced by a Stock Issuance Agreement which complies with the terms specified below. A. Purchase Price 1. The purchase price per share shall be fixed by the Plan Administrator, but shall not be less than eighty five per cent (85%) of the Fair Market Value per share of Common Stock on the issuance date. 2. Subject to the provisions of Section I of Article Five, shares of Common Stock may be issued under the Stock Issuance Program for any of the following items of consideration which the Plan Administrator may deem appropriate in each individual instance: (i) cash or check made payable to the Corporation, or (ii) past services rendered to the Corporation (or any Parent or Subsidiary). B. Vesting Provisions 1. Shares of Common Stock issued under the Stock Issuance Program may, in the discretion of the Plan Administrator, be fully and immediately vested upon issuance or may vest in one or more installments over the Participant's period of Service or upon attainment of specified performance objectives. The elements of the vesting schedule applicable to any unvested shares of Common Stock listed under the Stock Issuance Program, namely: (i) the Service period to be completed by the Participant or the performance objectives to be attained, (ii) the number of installments in which the shares are to vest, (iii) the interval or intervals (if any) which are to lapse between installments, and (iv) the effects which death, Permanent Disability or other event designated by the Plan Administrator is to have upon the vesting schedule, II-23 13 shall be determined by the Plan Administrator and incorporated into the Stock Issuance Agreement. 2. Any new, substituted or additional securities or other property (including money paid other than as a regular cash dividend) which the Participant may have the right to receive with respect to the Participants unvested shares of Common Stock by reason of any stock dividend, stock split, recapitalization, combination of shares, exchange of shares or other change affecting the outstanding Common Stock as a class without the Corporation's receipt of consideration shall be issued subject to (i) the same vesting requirements applicable to the Participant's unvested shares of Common Stock and (ii) such escrow arrangements as the Plan Administrator shall deem appropriate. 3. The Participant shall have full shareholder rights with respect to any shares of Common Stock issued to the Participant under the Stock Issuance Program, whether or not the Participant's interest in those shares is vested. Accordingly, the Participant shall have the right to vote such shares and to receive any regular cash dividends paid on such shares. 4. Should the Participant cease to remain in Service while holding one or more unvested shares of Common Stock issued under the Stock Issuance Program or should the performance objectives not be attained with respect to one or more such unvested shares of Common Stock, then those shares shall be immediately surrendered to the Corporation for cancellation, and the Participant shall have no further shareholder rights with respect to those shares. To the extent the surrendered shares were previously issued to the Participant for consideration paid in cash or cash equivalent (including the Participant's purchase-money indebtedness), the Corporation shall repay to the participant the cash consideration paid for the surrendered shares and shall cancel the unpaid principal balance of any outstanding purchase-money note of the Participant attributable to such surrendered shares. 5. The Plan Administrator may in its discretion waive the surrender and cancellation of one or more unvested shares of Common Stock (or other assets attributable thereto) which would otherwise occur upon the cessation of the Participant's Service or the non-completion of the vesting schedule applicable to such shares. Such waiver shall result in the immediate vesting of the Participant's interest in the shares of Common Stock as to which the waiver applies. Such waiver may be effected at any time, whether before or after the Participant's cessation of Service or the attainment of non- attainment of the applicable performance objectives. II-24 14 II CORPORATE TRANSACTION/CHANGE IN CONTROL A. All of the outstanding repurchase rights under the Stock Issuance Program shall terminate automatically, and all the shares of Common Stock subject to those terminated rights shall immediately vest in full, in the event of an Corporate Transaction. B. The Plan Administrator shall have the discretion, exercisable either at the time the unvested shares are issued or at any time while the Corporation's repurchase right remains outstanding, to provide for the automatic termination of one or more outstanding repurchase rights and the immediate vesting of the shares of Common Stock subject to those rights upon the Involuntary Termination of the Participant's Service within a specified period (not to exceed eighteen (18) months) following the effective date of any Change in Control. III. SHARE ESCROW/LEGENDS Unvested shares may, in the Plan Administrator's discretion, be held in escrow by the Corporation until the Participant's interest in such shares vests or may be issued directly to the Participant with restrictive legends on the certificates evidencing those unvested shares. ARTICLE FOUR AUTOMATIC OPTION GRANT PROGRAM I. OPTION TERMS A. SUCCESSOR PROGRAM. Shareholder approval of this Plan at the 1999 Annual Meeting shall also constitute approval of all option grants made to Eligible Directors pursuant to the provisions of this Automatic Option Grant Program. B. GRANT DATES. Option grants shall be made under the Plan on the dates specified below: 1. Each Eligible Director who is first elected or appointed as a non-employee Board member after the Effective Date shall automatically be granted, on the date of such initial election or appointment, a Non-Statutory Option to purchase 30,000 shares of Common Stock. 2. On the date of each Annual Shareholder Meeting, beginning with the 1999 Annual Meeting, each individual who is to continue to serve as an Eligible Director after such meeting, shall automatically be granted, whether or not such individual is standing for re-election as a Board member at that Annual Meeting, a Non-Statutory Option to purchase an additional 30,000 shares of Common Stock, provided such individual has served as a non-employee Board member for at least six (6) months prior to the date of such Annual Meeting. There shall be no limit on the number of such 30,000 share option II-25 15 grants any one Eligible Director may receive over his or her period of Board service. C. EXERCISE PRICE. 1. The exercise price per share shall be equal to one hundred percent (100%) of the Fair Market Value per share of Common Stock on the option grant date. 2. The exercise price shall be payable in one or more of the alternative forms authorized under the Discretionary Option Grant Program. Except to the extent the sale and remittance procedure specified thereunder is utilized, payment of the exercise price for the purchased shares must be made on the Exercise Date. D. OPTION TERM. Each option shall have a term of ten (10) years measured from the option grant date. E. EXERCISE AND VESTING OF OPTIONS. Each option shall be exercisable for one third of the options granted annually, commencing one year after the date of grant. However, any shares purchased under the option shall be subject to repurchase by the corporation, at the exercise price paid per share, upon the Optionee's cessation of Board service prior to vesting in those shares. The shares subject to each initial grant shall vest, in a series of three (3) successive equal annual installments over the Optionee's period of continued service as a Board member, with the first such installment to vest upon the Optionee's completion of one (1) year of Board service measured from the option grant date. The shares subject to each annual grant shall vest, and the Corporation's repurchase right with respect to those shares shall lapse, on the day immediately preceding the date of the next Annual Shareholders Meeting following the grant date, provided the Optionee continues in Board service through such day. F. EFFECT OF TERMINATION OF BOARD SERVICE. The following provisions shall govern the exercise of any options held by the Optionee at the time the Optionee ceases to serve as a Board member. (i) The Optionee (or, in the event of Optionee's death, the personal representative of the Optionee's estate or the person or persons to whom the option is transferred pursuant to the Optionee's will or in accordance with the laws of descent and distribution) shall have a twelve (12)-month period following the date of such cessation of Board service in which to exercise each such option. (ii) During the twelve (12)-month exercise period, the option may not be exercised in the aggregate for more than the number of vested shares of Common Stock for which the option is exercisable at the time of the Optionee's cessation of Board service. (iii) Should the Optionee cease to serve as a Board member by reason of death or Permanent Disability, then all shares at the time subject to the option shall immediately vest so that such option may, during the twelve (12)-month exercise period II-26 16 following such cessation of Board service, be exercised for all or any portion of such shares as fully-vested shares of Common Stock. (iv) In no event shall the option remain exercisable after the expiration of the option term. Upon the expiration of the twelve (12)-month exercise period or (if earlier) upon the expiration of the option term, the option shall terminate and cease to be outstanding for any vested shares for which the option has not been exercised. However, the option shall, immediately upon the Optionee's cessation of Board service, terminate and cease to be outstanding with respect to any shares in which the Optionee is not bested on the date of such cessation of Board service. II. CORPORATE TRANSACTION/CHANGE IN CONTROL/HOSTILE TAKE-0VER A. In the event of any Corporate Transaction, the shares of Common Stock at the time subject to each outstanding option under the Automatic Option Grant Program but not otherwise vested shall automatically vest in full so that each such option shall, immediately prior to the effective date of the Corporate Transaction, become exercisable for all of the shares of Common Stock at the time subject to such option and may be exercised for all or any portion of such shares as fully-vested shares of Common Stock. B. In the event of any Change in Control, the shares of Common Stock at the time subject to each outstanding option but not otherwise vested shall automatically vest in full so that each such option shall, immediately prior to the effective date of the Change in Control, become exercisable for all of the shares of Common Stock at the time subject to such option and may be exercised for all or any portion of such shares as fully-vested shares of Common Stock. C. Upon the occurrence of a Hostile Take-Over, the Optionee shall have a thirty (30)-day period in which to surrender to the Corporation each option grant held by him or her under this Automatic Option Grant Program. The Optionee shall in return be entitled to a cash distribution from the Corporation in an amount equal to the excess of (i) the Take-Over price of the shares of Common Stock at the time subject to the surrendered option (whether or not the Optionee is otherwise at the time vested in those shares) over (ii) the aggregate exercise price payable for such shares. Such cash distribution shall be paid within five (5) days following the surrender of the option to the Corporation. Such surrender right shall form a part of each option grant made under this Automatic Option Grant Program, and shareholder approval of this Plan shall constitute pre-approval of this Paragraph C. Accordingly, no approval of the Board or the Plan Administrator shall be required at the time of the actual option surrender and the cash distribution to which the optionee shall thereupon become entitled. D. The grant of options under the Automatic Option Grant Program shall in no way affect the right of the Corporation to adjust, reclassify, reorganize or otherwise change its capital or business structure or to merge, consolidate, dissolve, liquidate or sell or transfer all or any part of its business or assets. II-27 17 III. REMAINING TERMS The remaining terms of each option granted under the Automatic Option Grant Program shall be the same as the terms in effect for option grants made under the Discretionary Option Grant Program. ARTICLE FIVE MISCELLANEOUS I. FINANCING A. The Plan Administrator may permit any Optionee or Participant to pay the option exercise price under the Discretionary Option Grant Program or the purchase price for shares issued under the Stock Issuance Program by delivering a promissory note payable in one or more installments. The terms of any such promissory note (including the interest rate and the terms of repayment) shall be established by the Plan Administrator in its sole discretion. Promissory notes may be authorized with or without security or collateral. In all events, the maximum credit available to the Optionee or Participant may not exceed the sum of (i) the aggregate option exercise price or purchase price payable for the purchased shares plus (ii) any Federal, state and local income and employment tax liability incurred by the Optionee or the Participant in connection with the option exercise or share purchase. B. The Plan Administrator may, in its discretion, determine that one or more such promissory notes shall be subject to forgiveness by the Corporation in whole or in part upon such terms as the Plan Administrator may deem appropriate. II. TAX WITHHOLDING A. The Corporation's obligation to deliver shares of Common Stock upon the exercise of options or stock appreciation rights or upon the issuance or vesting of such shares under the Plan shall be subject to the satisfaction of all applicable Federal, state and local income and employment tax withholding requirements.
