Subject to the other provisions of this Section 6.03, Options shall vest and become exercisable at such time and in such installments as the Board shall provide in each individual Option Agreement. Notwithstanding the foregoing, the Board may, in its sole discretion, accelerate the time at which an Option or installment thereof may be exercised. Unless otherwise provided in this Section 6.03, in Section 6.04(a) or in the Option Agreement pursuant to which an Option is granted, an Option may be exercised when Accrued Installments accrue as provided in such Option Agreement and at any time thereafter until, and including, the day before the Option Termination Date. (b) Termination of Options. All installments of an Option shall expire and terminate on such date as the Board shall determine ("Option Termination Date"), which in no event shall be later than ten (10) years from the date such Option was granted (five (5) years in the case of an Incentive Stock Option granted to a Restricted Shareholder). (c) Termination of Employment other than by Death, Retirement or Total Disability. In the event that the employment of an Optionee with a Participating Company is terminated for any reason (other than death or Total Disability or retirement on or after reaching age 60), any installments under an Option held by such Optionee that have not accrued as of the employment termination date shall expire and become unexercisable as of the employment termination date. All Accrued Installments as of the employment termination date shall expire and become unexercisable as of the earlier of (i) three (3) months following the employment termination date; or (ii) the original Option Termination Date. For purposes of the Plan, an Optionee who is an employee or officer of any Participating Company shall not be deemed to have incurred a termination of his employment so long as such Optionee is an employee or officer of any Participating Company. (d) Leave of Absence. An approved leave of absence shall not constitute a termination of employment under the Plan. An approved leave of absence shall mean an absence approved pursuant to the policy of a Participating Company for military leave, sick leave, or other bona fide leave, not to exceed ninety (90) days or, if longer, as long as the employee's right to re-employment is guaranteed by contract, statute or the policy of a Participating Company. Notwithstanding the foregoing, in no event shall an approved leave of absence operate to make an Option exercisable after the original Option Termination Date. (e) Death, Retirement or Total Disability of Optionee. In the event that the employment of an Optionee with a Participating Company is terminated by reason of death, Total Disability, or retirement on or after reaching age sixty (60), any unexercised Accrued Installments of Options granted hereunder to such Optionee shall expire and become unexercisable as of the earlier of: 6 7 (i) The applicable Option Termination Date; or (ii) The first anniversary of the date of termination of employment of such Optionee by reason of the Optionee's death, Total Disability or retirement. Any such Accrued Installments of a deceased Optionee may be exercised prior to their expiration only by the person or persons to whom the Optionee's Option rights pass by will or the laws of descent and distribution. Any Option installments under such a deceased, disabled or retired Optionee's Option that have not accrued as of the date of the employee's termination of employment due to death, Total Disability or retirement shall expire and become unexercisable as of the employment termination date. (f) Termination of Affiliation of Participating Company. Notwithstanding the foregoing provisions of this Section 6.03, (i) in the case of an Optionee who is an employee or officer of a Participating Company other than the Company, upon an Affiliation Termination (as defined herein) of such Participating Company or an ORBCOMM Partnership, such Optionee shall be deemed (for all purposes of the Plan) to have incurred a termination of his employment for reasons other than death, retirement on or after age 60 or Total Disability, with such termination to be deemed effective as of the effective date of said Affiliation Termination and (ii) in the case of an Optionee who is an employee or officer of a Participating Company that is an ORBCOMM Partnership, upon an Affiliation Termination of such Participating Company, all unaccrued installments of any Option held by such Optionee shall vest and become Accrued Installments immediately prior to the effectiveness of such Affiliation Termination and thereafter each such Option shall expire and become unexercisable as of the earlier of (A) the applicable Option Termination Date, (B) the first anniversary of the Optionee's death, Total Disability or retirement on or after reaching age 60 or (C) three (3) months following the date the Optionee's ceases to be employed by any Participating Company or any ORBCOMM Partnership. As used herein, the term "Affiliation Termination" shall mean, with respect to a Participating Company, the termination of such Participating Company's status as an ORBCOMM Partnership or as a Parent or Subsidiary Corporation of the Company or of Orbital Sciences Corporation. 6.04 Exercise of Options.

For purposes of this Section 6.04(a), (i) the "value of Orbital Sciences Corporation's share of the Company" shall mean the sum of the percentage of the Company's Common Stock owned by Orbital Sciences Corporation multiplied by the then Fair Market Value of the Common Stock of the Company as determined by the Board, plus the principal amount of net intercompany indebtedness owed by the Company to Orbital Sciences Corporation; and (ii) "Orbital Sciences Corporation's investment in the Company" shall mean Orbital Sciences Corporation's investment in, and to the extent not reflected in the computation of such investment, the cumulative total of all unreimbursed expenses incurred, and expenditures made by Orbital Sciences Corporation on behalf 7 8 of, the Company, net of expenditures that are charged to Independent Research and Development or directly reimbursed by customers. Any such determination of the value of Orbital Sciences Corporation's share of the Company, or of Orbital Sciences Corporation's investment in the Company, made in good faith by the Board shall be conclusive and binding on the Company and all Optionees. (b) Subject to the restrictions in Section 6.04(a), an Option may be exercised in accordance with this Section 6.04 as to all or any portion of the Shares covered by an Accrued Installment of the Option, from time to time during the applicable option period, except that an Option shall not be exercisable with respect to fractions of a Share. Options may be exercised, in whole or in part, by giving written notice of exercise to the Company, which notice shall specify the number of Shares to be purchased and shall be accompanied by payment in full of the purchase price in accordance with Section 6.05. An Option shall be deemed exercised when such written notice of exercise has been received by the Company. No Shares shall be issued until full payment has been made and the Optionee has satisfied such other conditions as may be required by this Plan, as may be required by applicable laws, rules or regulations, or as may be adopted or imposed by the Board. Until the issuance of stock certificates, no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to Shares subject to an Option notwithstanding the exercise of the Option. No adjustment will be made for a dividend or other rights for which the record date is prior to the date the stock certificate is issued, except as provided in Section 6.09(a). 6.05 Payment of Option Exercise Price. (a) Except as otherwise provided in Section 6.05(b), the entire option exercise price shall be paid at the time the Option is exercised by cashier's check or such other means as deemed acceptable by the Board. (b) In the discretion of the Board (which, in the case of an Incentive Stock Option, shall be exercised only at the time of grant), an Optionee may elect to pay for all or some of the Optionee's Shares with Shares the Optionee has held for at least six (6) months, subject to all restrictions and limitations of applicable laws, rules and regulations and subject to the satisfaction of any conditions the Board may impose, including, but not limited to, the making of such representations and warranties and the providing of such other assurances that the Board may require with respect to the Optionee's title to the Shares used for payment of the exercise price. Such payment shall be made by delivery of certificates representing Shares, duly endorsed or with duly signed stock power attached, such Shares to be valued at the Fair Market Value of such Shares on the day immediately preceding the day notice of exercise is received by the Company. 6.06 Purchase by the Company of Shares Acquired Pursuant to Exercise of Option. (a) Valuation. Provided that there has not yet been a public offering (within the meaning of the Securities Act of 1933, as amended, and the rules and regulations thereunder) of the Company's Common Stock, all Shares acquired pursuant to exercise of an Option that as of the applicable Valuation Date (as hereinafter defined), have been held by an Optionee at least six (6) months from the date of exercise of the Option (such Shares, in each year, the "Payable Shares"), 8 9 shall, at the election of the Optionee exercised in the manner set forth herein, be purchased by the Company at a price per share equal to the Fair Market Value of a share of Common Stock on September 1, 1995, September 1, 1996 and September 1, 1997 and in subsequent years on March 1 and September 1 of each year (each such date is referred to as a "Valuation Date"); provided further that on the Valuation Date in 1995 only, no more than fifty percent (50%) of each Optionee's Payable Shares shall become subject to purchase by the Company. Within thirty (30) days after each such Valuation Date after Options are exercisable under Section 6.04(a), the Company shall cause the Fair Market Value of the Shares to be determined in accordance with Section 6.06(b) and shall notify each holder of Shares acquired pursuant to exercise of an Option of such Fair Market Value. Within thirty (30) days after receipt of such notice, each such holder of Shares may elect to have all or any portion of his or her Payable Shares be purchased by the Company at a price per share equal to such Fair Market Value by submitting to the Committee an irrevocable written notice of such election. The rights of an Optionee under this Section 6.06 may be exercised by the Optionee and any transferee specified in clause (ii) of Section 6.08(a) (in which case all references herein to "Optionee" shall refer to such transferee), but shall not be exercisable by any other holder of Shares, whether or not such holder acquired such Shares in a transfer permitted by Section 6.08(a). (b) Method of Valuation. The value of a Share of Company Common Stock on each Valuation Date shall be determined in good faith by the Committee, and any such determination shall be conclusive and binding on the Company and all Optionees and/or holders of Shares. In making any such determination of Fair Market Value, the Committee may, but shall not be required to, rely on a determination of Fair Market Value made by an independent appraiser or other appropriate financial professional selected by the Committee in its sole discretion and reasonably believed to be competent to make such determination. No member of the Committee shall have any personal liability to any Optionee and/or holder of Shares for any determination of Fair Market Value under this Section 6.06, or any act or omission in connection therewith, unless the Optionee and/or holder of Shares shall establish that such determination, act or omission was not made in good faith. (c) Closing of Purchase of Shares. The closing for any purchase of Shares pursuant to this Section 6.06 shall occur on such date within sixty (60) days of the giving by the Company of the notification required by Section 6.06(a) as the Company shall specify by five (5) business days' notice to each selling Optionee, at the offices of the Company at 11:00 a.m. local time, or at such other time and place as the parties to such sale may mutually agree. At the closing, the Optionee shall deliver to the Company a certificate or certificates representing the Shares to be purchased by the Company, duly endorsed for transfer, free and clear of any lien or encumbrance, in exchange for payment of the purchase price (i) by check, (ii) by delivery of certificates representing shares of Common Stock of Orbital Sciences Corporation having a Fair Market Value (determined in the manner provided in Section 2.10) as of the business day preceding the closing equal to the purchase price of the Shares, (iii) by delivery of a subordinated promissory note of the Company in the principal amount of the purchase price of the Shares, bearing interest at a rate equal to the then applicable federal short-term rate (determined pursuant to Section 1274(d) of the I.R.C.), providing for quarterly payments of interest and payment of the full principal amount on the first anniversary of the date of issuance, and containing provisions as approved by the Board in its sole 9 10 discretion providing for the subordination of such notes to such indebtedness, whether then existing or thereafter created, of the Company as is specified by the Board, including, without limitation, indebtedness for money borrowed or similar indebtedness, or (iv) any combination of the foregoing; provided, however, that no more than fifty percent (50%) of the purchase price for Shares may be paid by subordinated promissory note. Any payment in the form of shares of Orbital Sciences Corporation Common Stock shall be subject to all applicable federal and state securities laws restrictions and all other restrictions. (d) Limitations on Repurchase Obligations. Notwithstanding any other provision of this Section 6.06, the Company shall not be obligated to purchase Payable Shares (i) to the extent such purchase is not permitted under applicable law or under the terms of any of (A) the Company's then-existing debt instruments or agreements governing such debt instruments, (B) the then-existing terms of any class of preferred stock of the Company, or (C) a then-existing stockholders agreement to which the Company is a party; or (ii) in the event there has been a public offering (within the meaning of the Securities Act of 1933 as amended, and the rules and regulations thereunder) of the Company's Common Stock. 6.07 Options Not Transferable. Options granted under this Plan may not be sold, pledged, hypothecated, assigned, encumbered, gifted or otherwise transferred or alienated in any manner, whether voluntarily, by operation of law, pursuant to judicial process or otherwise, other than by will or the laws of descent and distribution, and may be exercised during the lifetime of an Optionee only by such Optionee. 6.08 Restrictions on Issuance or Transfer of Shares. (a) Until such time as the Company shall have consummated an underwritten public offering of Shares involving an aggregate public offering price of at least Five Million Dollars ($5,000,000), or the Shares are registered under the Exchange Act, no Shares issuable upon exercise of an Option shall be sold, assigned, encumbered, pledged, hypothecated, given away or in any other manner disposed of or transferred, whether voluntarily, by operation of law, pursuant to judicial process or otherwise, except (i) to the Company pursuant to Section 6.06 hereof, or (ii) upon the death of the holder thereof, Shares may be transferred and distributed by will or other instrument taking effect at death or by the laws of descent and distribution to such holder's estate, executors, administrators and personal representatives, and then to such holder's heirs, legatees or distributees, provided that no such transfer shall be effective until the recipient has delivered to the Company a written acknowledgment in form and substance reasonably satisfactory to the Company that such Shares are subject to the restrictions on disposition or transfer set forth in this Section 6.08(a). Any attempted transfer of Shares not in accordance with this Section 6.08(a) shall be null and void, and the Company shall not in any way give effect to any such disposition or transfer. (b) No Shares shall be issued or delivered upon exercise of an Option unless and until there shall have been compliance with all applicable requirements of the Securities Act of 1933, as amended, all applicable listing or quotation requirements of any national securities exchange or market on which Shares are then listed or quoted, and any other requirement of law or 10 11 of any regulatory body having jurisdiction over such issuance and delivery. The inability of the Company to obtain any required permits, authorizations or approvals necessary for the lawful issuance and sale of any Shares hereunder on terms deemed reasonable by the Board shall relieve the Company, the Board and any Committee of any liability in respect of the non-issuance or sale of such Shares as to which such requisite permits, authorizations or approvals shall not have been obtained. (c) As a condition to the granting or exercise of any Option, the Board may require the person receiving or exercising such Option to make any representation and/or warranty to the Company as may be required under any applicable law or regulation, including, but not limited to, a representation that the Option and/or Shares are being acquired only for investment and without any present intention to sell or distribute such Option and/or Shares, if such a representation is required under the Securities Act of 1933, as amended, or any other applicable law, rule or regulation. (d) The exercise of Options under the Plan is conditioned on approval of the Plan by the vote or written consent of a majority of the holders of outstanding Shares of the Company's Common Stock within twelve (12) months of the adoption of the Plan. In the event such stockholder approval is not obtained within such time period, any Options granted hereunder shall be void. 6.09 Option Adjustments. (a) If the outstanding Shares of Common Stock of the Company are increased, decreased, changed into or exchanged for a different number or kind of shares of the Company through reorganization, recapitalization, reclassification, stock dividend, stock split or reverse stock split or other similar transaction, the Board shall make a proportionate adjustment in the number or kind of shares and the per-share option price thereof, which may be issued in the aggregate and to individual Optionees upon exercise of Options granted under the Plan; provided, however, that no such adjustment need be made if, upon the advice of counsel, the Board determines that such adjustment may result in the receipt of federally taxable income to holders of Options granted hereunder or the holders of Common Stock or other classes of the Company's securities. (b) Upon the occurrence of a Terminating Transaction, as of the effective date of such Terminating Transaction, the Plan and any then outstanding Options (whether or not vested) shall terminate unless (i) provision is made in writing in connection with such transaction for the continuance of the Plan and for the assumption of such Options, or for the substitution for such Options of new options covering the securities of any successor or survivor corporation in the Terminating Transaction or an affiliate thereof, with such adjustments as the Board deems appropriate with respect to the number and kind of securities and the per-share exercise price under such substituted options, in which event the Plan and such outstanding Options shall continue or be replaced, as the case may be, in the manner and under the terms so provided; or (ii) the Board otherwise shall provide in writing for such adjustments as it deems appropriate in the terms and conditions of the then outstanding Options (whether or not vested), including, without limitation, (A) accelerating the vesting of outstanding Options; and/or (B) providing for the cancellation of 11 12 Options and their automatic conversion into the right to receive the securities or other properties which a holder of Shares underlying such Options would have been entitled to receive upon the consummation of such Terminating Transaction had such Shares been issued and outstanding (net of the appropriate option exercise prices). If, pursuant to the foregoing provisions of this paragraph (b), the Plan and the Options shall terminate by reason of occurrence of a Terminating Transaction without provision for any of the action(s) described in clause (i) and/or (ii) hereof, then any Optionee holding outstanding Options shall have the right, at such time immediately prior to the consummation of the Terminating Transaction as the Board shall designate, to exercise their Options to the full extent not theretofore exercised, including any installments which have not yet become Accrued Installments. (c) Except to the extent required in order to retain the qualification of an Option as an Incentive Stock Option under I.R.C. Section 422, to the maximum extent possible, any adjustments authorized under this Section 6.09 with respect to any outstanding Options shall be made by means of appropriate adjustments to the number of Shares (or other securities) and the option exercise price therefor under the unexercised portions of such outstanding Options, but without changing the aggregate exercise price applicable to said unexercised portions. In all cases, the nature and extent of adjustments under this Section 6.09 shall be determined by the Board in its sole discretion, and any such determination as to what adjustments shall be made, and the extent thereof, shall be final and binding. No fractional shares of stock shall be issued under the Plan pursuant to any such adjustment. 6.10 Taxes. The Board shall make such provisions and take such steps as it deems necessary or appropriate for the withholding of any federal, state, local and other tax required by law to be withheld with respect to the grant or exercise of an Option under the Plan, or with respect to the disposition of Shares acquired pursuant to the exercise of an Option pursuant to the Plan, including, but without limitation, the deduction of the amount of any such withholding tax from any compensation or other amounts payable to an Optionee by any member of the Participating Companies, or requiring an Optionee (or the Optionee's beneficiary or legal representative), as a condition of granting or exercising an Option, to pay to any member of the Participating Companies any amount required to be withheld, or to execute such other documents as the Board deems necessary or desirable in connection with the satisfaction of any applicable withholding obligation.
