ARTICLE VI

STOCK OPTIONS

     6.01 Grant of Options. One or more Options may be granted to any eligible employee. Options shall be embodied in an Agreement in a form approved by the Committee.

     6.02 Incentive Stock Options/Nonqualified Stock Options. The Agreement may provide for “incentive stock options” that are intended to satisfy the requirements of Section 422A of the Code, or such other options that are not intended to satisfy the requirements of Section 422A of the Code (hereinafter described as “nonqualified stock options”), that entitle the holder to purchase from the Company a stated number of shares of Common Stock at the price set forth in the Agreement. Each Option shall be an incentive stock option or a nonqualified stock option as specified in the Agreement. All Options that are not identified as incentive stock options in the Agreement are intended to be nonqualified stock options.

- 4 -

     6.03 Option Price. Except as provided in Section 6.04, the exercise price per share of an Option shall be an amount not less than 100% of the Fair Market Value per share of the Common Stock on the date of grant of such Option (or, in the case of a grant of an incentive stock option to a prospective employee, the date the grant becomes effective).

     6.04 Additional Provisions Applicable to Incentive Stock Options. The aggregate Fair Market Value (determined at the time any incentive stock option is granted) of the Common Stock with respect to any Participant’s incentive stock options, together with incentive stock options granted under any other plan of the Company or any subsidiary (as defined in Code Section 425 (f)), that are exercisable for the first time by such Participant during any calendar year shall not exceed $100,000. In the event that a Participant holds incentive stock options that become first exercisable (as a result of acceleration of exercisability under the Plan or an Agreement, or otherwise) in any one calendar year for shares having a Fair Market Value at the date of grant in excess of $100,000, then the most recently granted of such incentive stock options, to the extent that they are exercisable for shares having an aggregate Fair Market Value in excess of $100,000, shall be deemed to be nonqualified stock options.

     No incentive stock option may be granted under the Plan to any person who owns, directly or indirectly, within the meaning of Sections 422A(b) (6) and 425(d) of the Code, at the time the incentive stock option is granted, stock possessing more than 10% of the total combined voting power of all classes of stock of the Company or any subsidiary (as defined in Code Section 425(f)) unless the exercise price is at least 110% of the Fair Market Value of the shares subject to the incentive stock option, determined on the date of the grant, and the incentive stock option by its terms is not exercisable after the expiration of five years from the date such incentive stock option is granted.

     6.05 Option Exercise Period. No Option shall be exercisable less than one year nor more than ten years from the date the Option was granted.

     6.06 Employee Status. In the event that the terms of any Option provide that it may be exercised only during employment or within a specified period of time after termination of employment, the Committee may decide in each case to what extent leaves of absence for governmental or military service, illness, temporary disability, or other reasons shall not be deemed terminations of employment.

- 5 -

     6.07 Nontransferability. Any Option granted under the Plan shall not be transferable by the Participant except by will or the laws of descent and distribution and shall be exercisable during the Participant’s lifetime only by the Participant or, in the event of the Participant’s mental or physical incapacity, by his legal representative.

     6.08 Exercisability.

     (i)  Generally. Subject to the other provisions of the Plan, an Option may be exercised in whole at any time or in part, from time to time, at such times and in compliance with such requirements as set forth in the Agreement. An Option granted under the Plan may be exercised with respect to any number of whole shares less than the full number for which the Option could be exercised. Such partial exercise of an Option shall not affect the right to exercise the Option from time to time in accordance with the Plan with respect to remaining shares subject to the Option. Upon the exercise of an Option granted in connection with Stock Appreciation Rights, the Participant shall surrender unexercised the Stock Appreciation Rights or, if the Option is not exercised in full, any portion of the Stock Appreciation Rights to which the exercised portion of the Option is related.

     (ii)  Death, Disability, or Retirement. In the event of a Participant’s death or disability, Options shall become exercisable either according to the terms of the Agreement or on a pro-rata basis based upon the vesting period specified in the Agreement, whichever permits the Participant or beneficiary to exercise Options for a greater number of shares of Common Stock. For purposes of this provision, “disability” means a physical or mental condition which prevents the Participant from engaging in any substantially gainful activity. In the event of normal retirement or early retirement as provided under the employees’ pension plan of the Company or the Affiliate employing the Participant, the Committee may accelerate the exercisability of Options.

     6.09 Exercise; Payment.

     (i)  Exercise. Unless provided otherwise in an Agreement, an Option shall be exercised, in whole or in part, by a written notice delivered to the Committee, which notice shall contain the provision or authorization with respect to tax withholding required by Section 14.06(I). The Option shall be deemed to have been exercised when such notice is received by the Committee.

- 6 -

     (ii)  Payment. Payment of the Option exercise price shall be made in cash or a cash equivalent acceptable to the Committee. If the Agreement so provides, payment of all or part of the Option exercise price may be made in shares of Common Stock, or through such other arrangements as specified in the Agreement. If Common Stock is used to pay all or part of the Option exercise price, the shares surrendered must have a Fair Market Value (determined as of the day of exercise) that is not less than such price or part thereof.

     6.10 Shareholder Rights. No Participant shall, as a result of having been granted any Option, have any rights as a shareholder until the date the Participant becomes a shareholder of record of shares of Common Stock upon exercise of such Option.

ARTICLE VII

     (i)  Initial Awards. The initial Awards of Restricted Stock shall be by action of the Board taken on June 28, 1989, effective July 3, 1989.

- 7 -

ment. The Committee may decide in each case to what extent leaves of absence for governmental or military service, illness, temporary disability, or other reasons shall not be deemed a termination of employment.

     7.03 Restriction Period.

     (i)  Initial Awards. For those initial Awards of Restricted Stock granted by the Board on June 28, 1989, there shall be a five-year restriction period during which restrictions shall lapse as follows: 50% after the third anniversary of the granting of the Award; 25% after the fourth anniversary of the granting of the Award; and the final 25% after the fifth anniversary of the granting of the Award.

     (ii)  Subsequent Awards. The Committee shall establish restriction periods applicable to any Award made subsequent to the initial Awards described in Section 7.01 (I).

     7.04 Death or Disability; Retirement.

     (i)  Death or Disability. Restrictions on Restricted Stock shall lapse on a pro-rata basis in the event of a Participant’s death or disability. On the basis of a five-year restriction period, the restrictions will lapse at the rate of 20% for each anniversary of the granting of the Award that has passed before the occurrence of the Participant’s death or disability. For purposes of this provision, “disability” means a physical or mental condition which prevents the Participant from engaging in any substantially gainful activity.

     (ii)  Retirement. In the event of normal retirement or early retirement as provided under the Company’s Employees’ Pension Plan, the Committee may terminate any remaining restrictions on Restricted Stock.

     7.05 Shareholder Rights. While the shares are Restricted Stock, a Participant shall have all rights of a shareholder with respect to such shares, including the right to receive dividends and to vote the shares; provided, however, that (i) a Participant may not sell, transfer, pledge, exchange, hypothecate, or otherwise dispose of shares of Restricted Stock and (ii) the Company shall retain custody of the certificates evidencing shares of Restricted Stock.

Stock Appreciation Rights shall be subject to such terms and conditions not inconsistent with the Plan as the Committee shall impose.

     8.02 Exercisability. Stock Appreciation Rights granted in connection with an Option shall be exercisable to the extent the Option is exercisable. Stock Appreciation Rights not granted in connection with an Option shall be exercisable pursuant to such terms and conditions established by the Committee in the Award.

     8.03 Failure to Exercise. If a Participant who has been granted Stock Appreciation Rights has not exercised such rights as of the day the Stock Appreciation Rights expire due to passage of time, then such rights shall be deemed to have been exercised by the Participant on such day. The foregoing sentence applies only if the Fair Market Value of one share of Common Stock on such day exceeds the Fair Market Value of one share of Common Stock on the day the Stock Appreciation Rights were granted.

- 9 -

or shares of Common Stock or a combination thereof as set forth in the Agreement at the time of grant) equal to the product of the excess of the Fair Market Value of one share of Common Stock at the date of exercise over the Option price, multiplied by the number of shares called for by the Stock Appreciation Rights (or portion thereof) which are so exercised. Upon exercise of Stock Appreciation Rights not granted in connection with an Option, the Participant shall be entitled to payment (in cash or shares of Common Stock or a combination thereof as set forth in the Agreement at the time of grant) equal to the product of the excess of the Fair Market Value of one share of Common Stock at the date of exercise over the Fair Market Value of one share of Common Stock at the date of grant of the Stock Appreciation Rights, multiplied by the number of shares called for by the Stock Appreciation Rights (or portion thereof) which are so exercised. The value of any Common Stock payable upon exercise of Stock Appreciation Rights shall be the Fair Market Value of the Common Stock on the day on which the Stock Appreciation Rights are exercised. Solely for purposes of Article V of the Plan, to the extent that Stock Appreciation Rights granted in connection with an Option are exercised, such Option shall be deemed to have been exercised, and shall not be deemed to have lapsed.

     8.05 Nontransferability. Stock Appreciation Rights granted under the Plan shall not be transferable by the Participant except by will or the laws of descent and distribution and shall be exercisable during the Participant’s lifetime only by the Participant or, in the event of the Participant’s mental or physical incapacity, by his legal representative.

The Agreement shall specify the extent to which satisfaction of such specified objectives will entitle the Participant to receive shares of Common Stock of the Company or cash at the end of the performance period.

     9.02 Performance Period. The measuring period to establish the performance objectives set forth in a Performance Share Agreement shall be no less than three years.

     9.03 Form of Payment.

- 11 -

not to any right to the actual dividends on the underlying shares or to the underlying shares themselves. Such Awards of Dividend Units may be combined with other Awards. Payments in respect of Dividend Units will be made at dividend payment dates and not accumulated.

ARTICLE XI

ADJUSTMENT UPON CHANGE IN CAPITALIZATION

     Should the Company effect one or more Common Stock dividends, stock split-ups, subdivisions, or consolidations of shares or other changes in capitalization, then the maximum number of shares that may be subject to Awards under the Plan shall be proportionately adjusted, and the terms of outstanding Awards shall be adjusted, as the Committee in its discretion shall determine to be equitably required.

     (i)  Generally. Either the Company or an Affiliate, as appropriate, shall have the right to deduct from all Awards paid in cash any federal, state, or local taxes as it deems to be required by law to be withheld with respect to such cash payments. In the case of Awards paid in shares of Common Stock, the Participant receiving such Common Stock may be required to pay to the Company or an Affiliate, as appropriate, the amount of any such taxes which the Company or Affiliate is required to withhold with respect to such Common Stock. At the request of a Participant, or as required by law, such sums as may be required for the payment of any estimated or accrued income tax liability may be withheld or paid to the Company or an Affiliate, as appropriate, and paid over to the governmental entity entitled to receive the same.

     (ii)  Cashless Withholding. Participants may elect (an “Election”) to have withheld shares of Common Stock (A) to be issued pursuant to the exercise of an Option or Stock Appreciation Rights, (B) which have become freely transferable pursuant to the termination of restrictions on Restricted Stock, or (C) which are issued pursuant to a Performance Share Award, or the Participant may make an Election to surrender to the Company shares already

owned by the Participant (which may be shares of Common Stock previously received pursuant to an Award), which shall be sufficient in value to satisfy applicable tax withholding obligations, or such other withholding arrangements requested by the Participant or otherwise required as specified above, in connection with shares received pursuant to an Award. For purposes of such withholding or surrender, the shares withheld or surrendered shall be valued at their Fair Market Value on the date as of which the Participant first becomes subject to taxation for federal income tax purposes in respect of shares of Common Stock received upon exercise of the Option or Stock Appreciation Rights, which have become freely transferable upon the termination of restrictions on Restricted Stock, or which are issued under a Performance Share Award, whichever is applicable (the “Tax Date”). If the Fair Market Value on the Tax Date of the number of whole shares of Common Stock withheld or surrendered pursuant to an Election exceeds the withholding or other applicable tax obligations, a fractional share shall not be issued or returned for the excess, but an amount equal to the excess shall be paid to the Participant by the Company in cash as soon as reasonably practicable after the amount of such excess is determined by the Company. An Election may be made by a Participant with respect to all or part of a particular Option or Stock Appreciation Rights exercise, termination of restrictions on Restricted Stock, or issuance of shares under a Performance Share Award, to all or a specified class of previously granted Options, Stock Appreciation Rights, Restricted Stock, or Performance Share Awards, and/or to all or a specified class of Options, Stock Appreciation Rights, Restricted Stock, or Performance Share Awards which may be granted in the future. The Election shall specify whether the Participant elects to have withheld shares issued pursuant to the Award to which the Election relates, or to surrender already-owned shares of Common Stock. If the Participant elects to surrender already-owned shares of Common Stock, the Election shall be accompanied by certificates, with accompanying stock powers signed in blank, for a sufficient number of such shares of Common Stock.

     An Election by a Participant shall be made prior to the applicable Tax Date and also shall meet each of the following additional requirements:

     14.07 Government and Other Regulations. The obligation of the Company to make payment of Awards in Common Stock or otherwise shall be subject to all applicable laws, rules, and regulations, and to such approvals by any government agencies as may be required.

- 19 -

The Company shall be under no obligation to register under the Securities Act of 1933, as amended, or under any state securities or Blue Sky laws any of the shares of Common Stock issued, delivered, or paid in settlement under the Plan. If Common Stock awarded under the Plan may in certain circumstances be exempt from such registration, the Company may restrict its transfer in such manner as it deems advisable to ensure such exempt status.

     14.08 Reliance on Reports. Each member of the Committee shall be fully justified in relying or acting in good faith upon any report made by the independent public accountants of the Company and upon any other information furnished in connection with the Plan. In no event shall any person who is or shall have been a member of the Committee be liable for any determination made, any other action taken, or any omission to act in reliance upon any such report or information.

     14.09 Company Successors. In the event the Company becomes a party to a merger, consolidation, sale of substantially all of its assets, or any other corporate reorganization in which the Company will not be the surviving corporation or in which the holders of the Common Stock will receive securities of another corporation (in any such case, the “New Company”), then the New Company shall assume the rights and obligations of the Company under the Plan.

     14.10 Governing Law. All matters relating to the Plan, any Awards, or any Agreements, shall be governed by the laws of the District of Columbia, without regard to the principles of conflict of laws.

     14.11 Relationship to Other Benefits. No payment under the Plan shall be taken into account in determining any benefits under any other pension, retirement, profit-sharing, or other employee benefit plan of the Company or any Affiliate.

     14.12 Expenses. The expenses of administering the Plan shall be borne by the Company.

     14.13 Proceeds. Any cash proceeds received by the Company under the Plan shall be used for general corporate purposes, and any shares of Common Stock withheld by or paid to the Company under the Plan shall be held by the Company as treasury stock or shall be canceled, as the Company in its discretion shall determine.

ARTICLE XV

AMENDMENT

     The Board may amend the Plan from time to time. No amendment may become effective until shareholder approval is obtained if such approval is required by any federal or state law or regulation or the rates of any stock exchange on which the Common Stock may be listed, or if the Board in its discretion determines that the obtaining of such shareholder approval is for any reason advisable. No amendment shall, without a Participant’s consent, adversely affect any rights of such Participant under any Award outstanding at the time such amendment is made.

ARTICLE XVI

EFFECTIVE DATE; DURATION OF THE PLAN

     The effective date of the Plan is June 28, 1989, subject to shareholder approval. Unless sooner terminated by the Board, the Plan shall terminate on June 27, 1999; provided, however, that any Award outstanding at the time of such termination shall continue in full force and effect and shall continue to be governed by the Plan and its applicable Agreement until the Award expires or is discharged by its terms.
