     3.1 Administration.

     (a) The Committee shall administer the Plan. The Committee shall have exclusive power to (i) make Awards, (ii) determine when and to whom Awards will be granted, the form of each Award, the amount of each Award, and any other terms or conditions of each Award consistent with the Plan, and (iii) determine whether, to what extent and under what circumstances, Awards may be settled, paid or exercised in cash, Shares or other Awards, or other property or canceled, forfeited or suspended. Each Award shall be subject to an Agreement authorized by the Committee. A majority of the members of the Committee shall constitute a quorum for any meeting of the Committee, and acts of a majority of the members present at any meeting at which a quorum is present or the acts unanimously approved in writing by all members of the Committee shall be the acts of the Committee. Notwithstanding the foregoing, the Board shall have the sole and exclusive power to administer the Plan with respect to Awards granted to Outside Directors.

     (b) Solely for purposes of determining and administering Awards to Participants who are not Insiders, the Committee may delegate all or any portion of its authority under the Plan to one or more persons who are not Non-Employee Directors.

     (c) To the extent within its discretion and subject to Plan Sections 15 and 16, other than price, the Committee may amend the terms and conditions of any outstanding Award.

     (d) It is the intent that the Plan and all Awards granted pursuant to it shall be administered by the Committee so as to permit the Plan and Awards to comply with Exchange Act Rule 16b-3, except in such instances as the Committee, in its discretion, may so provide. If any provision of the Plan or of any Award would otherwise frustrate or conflict with the intent expressed in this Section 3.1(d), that provision to the extent possible shall be interpreted and deemed amended in the manner determined by the Committee so as to avoid the conflict. To the extent of any remaining irreconcilable conflict with this intent, the provision shall be deemed void as applicable to Insiders to the extent permitted by law and in the manner deemed advisable by the Committee.

     (e) The Committee’s interpretation of the Plan and of any Award or Agreement made under the Plan and all related decisions or resolutions of the Board or Committee shall be final and binding on all parties with an interest therein. Consistent with its terms, the Committee shall have the power to establish, amend or waive regulations to administer the Plan. In carrying out any of its responsibilities, the Committee shall have discretionary authority to construe the terms of the Plan and any Award or Agreement made under the Plan.

     3.2 Indemnification. Each person who is or shall have been a member of the Committee, or of the Board, and any other person to whom the Committee delegates authority under the Plan, shall be indemnified and held harmless by the Company, to the extent permitted by law, against and from any loss, cost, liability or expense that may be imposed upon or reasonably incurred by such person in connection with or resulting from any claim, action, suit or proceeding to which such person may be a party or in which such person may be involved by reason of any action taken or failure to act, made in good faith, under the Plan and against and from any and all amounts paid by such person in settlement thereof, with the Company’s approval, or paid by such person in satisfaction of any

judgment in any such action, suit or proceeding against such person, provided such person shall give the Company an opportunity, at the Company’s expense, to handle and defend the same before such person undertakes to handle and defend it on such person’s own behalf. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such person or persons may be entitled under the Company’s Certificate of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless.

     4.  Shares Available Under the Plan and Maximum Awards.

     4.1 Number of Shares Available for Grants . Subject to adjustment as provided in Sections 4.1(a) and 16 herein, the number of Shares hereby reserved for issuance to Participants under the Plan shall be 5,750,000. Any Shares that are subject to Awards of Options shall be counted against the maximum Share limitation as one Share for every one Share granted, and Awards of Stock Appreciation Rights shall be counted against this maximum Share limitation as equal to the number of Shares to which such Stock Appreciation Rights relate. Any Shares that are subject to Full Value Awards shall be counted against this maximum Share limitation as 1.30 Shares for every one Share granted. The Shares to be delivered under the Plan will be made available from authorized but unissued Shares or issued Shares that are held in the Company’s treasury.

     (a) Any Shares subject to an Award under this Plan that expires, is forfeited, cancelled, or returned to the Company for failure to satisfy vesting requirements, or otherwise terminates without payment being made thereunder shall, to the extent of such expiration, forfeiture, cancellation, return or termination, again be available for grant under the Plan. Each Share that again becomes available for grant pursuant to the preceding sentence shall increase the total number of Shares remaining available for Awards by (i) one Share if such Share was subject to an Option or Stock Appreciation Right granted under the Plan, and (ii) 1.30 Shares if such Share was subject to a Full Value Award. The following Shares will, however, continue to be charged against the foregoing maximum Share limitations and will not again become available for grant: (i) Shares tendered by the Participant or withheld by the Company in payment of the purchase price of an Option, (ii) Shares tendered by the Participant or withheld by the Company to satisfy any tax withholding obligation with respect to an Award, and (iii) Shares subject to a Stock Appreciation Right that are not issued in connection with the settlement of the Stock Appreciation Right upon its exercise.

     (b) Where two or more types of Awards (all of which are payable in Shares) are granted to a Participant in tandem with each other, such that the exercise of one type of Award with respect to a number of Shares cancels at least an equal number of Shares of the other, each such joint Award shall be deemed to be the equivalent of the maximum number of Shares available under the largest single Award.

     Additional rules for determining the number of Shares granted under the Plan may be made by the Committee as it deems necessary or desirable.

     (c) No fractional Shares may be issued under the Plan; however, cash shall be paid in lieu of any fractional Share in settlement of an Award.

     4.2 Individual Award Limitations . Subject to adjustment pursuant to Plan Section 16, the maximum number of Shares that may be awarded to a Participant in any calendar year in the form of Options is 250,000, the maximum number of Shares that may be awarded to a Participant in any calendar year in the form of Restricted Stock is 100,000, and the maximum number of Shares that may be awarded to a Participant in any calendar year in the form of Stock Appreciation Rights is 100,000.

     5.  Eligibility. Participation in the Plan shall be limited to Employees and to individuals or entities who are not Employees but who provide services to the Company or an Affiliate, including services provided in the capacity of a consultant, advisor or director. The granting of Awards is solely at the discretion of the Committee, except that Incentive Stock Options may only be granted to Employees. References herein to “employed,” “employment” or similar terms (except “Employee”) shall include the providing of services in any capacity or as a director. Neither the transfer of employment of a Participant between any of the Company or its Affiliates, nor a leave of absence granted to such Participant and approved by the Committee, shall be deemed a termination of employment for purposes of the Plan.

     6.  General Terms of Awards.

     6.1 Amount of Award. Each Agreement shall set forth the number of Shares of Restricted Stock, Stock or Performance Units subject to the Agreement, or the number of Shares to which the Option subject to the Agreement

applies or with respect to which payment upon the exercise of the Stock Appreciation Right subject to the Agreement is to be determined, as the case may be, together with such other terms and conditions applicable to the Award as determined by the Committee acting in its sole discretion.

     6.2 Term. Each Agreement, other than those relating solely to Awards of Shares without restrictions, shall set forth the Term of the Option, Stock Appreciation Right, Restricted Stock or other Award or the Performance Cycle for the Performance Units, as the case may be. Acceleration of the expiration of the applicable Term is permitted, upon such terms and conditions as shall be set forth in the Agreement, which may, but need not, include, without limitation, acceleration in the event of the Participant’s death or retirement. Acceleration of the Performance Cycle of Performance Units shall be subject to Plan Section 11.2. Each award granted to a Participant shall have such Term as the Committee shall determine at the time of grant; provided, however, that any such Term shall not exceed 10 years.

     6.3 Transferability. Except as provided in this Section, during the lifetime of a Participant to whom an Award is granted, only that Participant (or that Participant’s legal representative) may exercise an Option or Stock Appreciation Right, or receive payment with respect to Performance Units or any other Award. No Award of Restricted Stock (before the expiration of the restrictions), Options, Stock Appreciation Rights or Performance Units or other Award may be sold, assigned, transferred, exchanged or otherwise encumbered other than to a Successor in the event of a Participant’s death or pursuant to a qualified domestic relations order as defined in the Code or Title 1 of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), or the rules thereunder; any attempted transfer in violation of this Section 6.3 shall be of no effect. Notwithstanding the immediately preceding sentence, the Committee, in an Agreement or otherwise at its discretion, may provide that the Award (other than Incentive Stock Options) may be transferable to a Transferee if the Participant does not receive any consideration for the transfer. Any Award held by a Transferee shall continue to be subject to the same terms and conditions that were applicable to that Award immediately before the transfer thereof to the Transferee. For purposes of any provision of the Plan relating to notice to a Participant or to acceleration or termination of an Award upon the death, disability or termination of employment of a Participant the references to “Participant” shall mean the original grantee of an Award and not any Transferee.

     6.4 Termination of Employment. Except as otherwise determined by the Committee or provided by the Committee in an Agreement, in case of a Participant’s termination of employment, the following provisions shall apply:

     (a)  Options and Stock Appreciation Rights.

     (i) If a Participant’s employment or other relationship with the Company and its Affiliates terminates because of the Participant’s death, then any Option or Stock Appreciation Right that has not expired or been terminated shall become exercisable in full if the Participant’s employment or other relationship with the Company and its Affiliates has been continuous between the date the Option or Stock Appreciation Right was granted and a date not more than three months prior to such death, and may be exercised by the Participant’s Successor at any time, or from time to time, within one year after the date of the Participant’s death.

     (ii) If a Participant’s employment or other relationship with the Company and its Affiliates terminates because the Participant is disabled (within the meaning of Section 22(e)(3) of the Code), then any Option or Stock Appreciation Right that has not expired or been terminated shall become exercisable in full if the Participant’s employment or other relationship with the Company and its Affiliates has been continuous between the date the Option or Stock Appreciation Right was granted and the date of such disability, and the Participant or the Participant’s Successor may exercise such Option or Stock Appreciation Right at any time, or from time to time, within one year after the date of the Participant’s disability.

     (iii) If a Participant’s employment terminates for any reason other than death or disability, then any Option or Stock Appreciation Right that has not expired or been terminated shall remain exercisable for three months after termination of the Participant’s employment, but, unless otherwise provided in the Agreement, only to the extent that such Option or Stock Appreciation Right was exercisable immediately prior to such Participant’s termination of employment; provided, however, that if the Participant is an Outside Director, the Option or Stock Appreciation Right shall remain exercisable until the expiration of the Term after such Outside Director ceases to be a director of the Company but, unless otherwise provided in the Agreement, only to the extent that such Option or Stock Appreciation Right was exercisable immediately prior to such Outside Director ceasing to be a director.

     (iv) Notwithstanding the foregoing Plan Sections 6.4(a)(i), (ii) and (iii), in no event shall an Option or a Stock Appreciation Right be exercisable after the expiration of the Term of such Award. Any Option or Stock Appreciation Right that is not exercised within the periods set forth in Plan Sections 6.4 (i), (ii) and (iii), except as otherwise provided by the Committee in the Agreement, shall terminate as of the end of the periods described in such Sections.

     (b)  Performance Units. If a Participant’s employment or other relationship with the Company and its Affiliates terminates during a Performance Cycle because of death or disability, or under other circumstances provided by the Committee in its discretion in the Agreement or otherwise, the Participant, unless the Committee shall otherwise provide in the Agreement, shall be entitled to a payment with respect to Performance Units at the end of the Performance Cycle based upon the extent to which achievement of performance targets was satisfied at the end of such period (as determined at the end of the Performance Cycle) and prorated for the portion of the Performance Cycle during which the Participant was employed by the Company or its Affiliates. Except as provided in this Section 6.4(b) or in the Agreement, if a Participant’s employment or other relationship with the Company and its Affiliates terminates during a Performance Cycle, then such Participant shall not be entitled to any payment with respect to that Performance Cycle.

     (c)  Restricted Stock Awards. Unless otherwise provided in the Agreement, in case of a Participant’s death or disability, the Participant shall be entitled to receive a number of Shares of Restricted Stock under outstanding Awards that has been prorated for the portion of the Term of the Awards during which the Participant was employed by the Company and its Affiliates, and, with respect to such Shares, all restrictions shall lapse. Any Shares of Restricted Stock as to which restrictions do not lapse under the preceding sentence shall terminate at the date of the Participant’s termination of employment and such Shares of Restricted Stock shall be forfeited to the Company.

     6.5 Rights as Stockholder. Each Agreement shall provide that a Participant shall have no rights as a stockholder with respect to any securities covered by an Award unless and until the date the Participant becomes the holder of record of the Stock, if any, to which the Award relates.

     7.  Restricted Stock Awards.

     (a) An Award of Restricted Stock under the Plan shall consist of Shares subject to restrictions on transfer and conditions of forfeiture, which restrictions and conditions shall be included in the applicable Agreement. The Committee may provide for the lapse or waiver of any such restriction or condition based on such factors or criteria as the Committee, in its sole discretion, may determine.

     (b) Except as otherwise provided in the applicable Agreement, each Stock certificate issued with respect to an Award of Restricted Stock shall either be deposited with the Company or its designee, together with an assignment separate from the certificate, in blank, signed by the Participant, or bear such legends with respect to the restricted nature of the Restricted Stock evidenced thereby as shall be provided for in the applicable Agreement.

     (c) The Agreement shall describe the terms and conditions by which the restrictions and conditions of forfeiture upon awarded Restricted Stock shall lapse. Upon the lapse of the restrictions and conditions, Shares free of restrictive legends, if any, relating to such restrictions shall be issued to the Participant or a Successor or Transferee.

     (d) A Participant or a Transferee with a Restricted Stock Award shall have all the other rights of a stockholder including, but not limited to, the right to receive dividends and the right to vote the Shares of Restricted Stock.

     (e) No more than 1,000,000 of the total number of Shares available for Awards under the Plan shall be issued during the term of the Plan as Restricted Stock. This limitation shall be calculated pursuant to the applicable provisions of Plan Sections 4 and 16.

     8.  Other Awards. The Committee may from time to time grant Stock and other Awards under the Plan including, without limitation, those Awards pursuant to which Shares are or may in the future be acquired, Awards denominated in Stock units, securities convertible into Stock and phantom securities. The Committee, in its sole discretion, shall determine the terms and conditions of such Awards provided that such Awards shall not be inconsistent with the terms and purposes of the Plan. The Committee may, at its sole discretion, direct the Company to issue Shares subject to restrictive legends and/or stop transfer instructions that are consistent with the terms and conditions of the Award to which the Shares relate. No more than 50,000 of the total number of Shares available for Awards under the Plan shall be issued during the term of the Plan in the form of Stock without restrictions. This limitation shall be calculated pursuant to the applicable provisions of Plan Sections 4 and 16.

     9.  Stock Options.

     9.1 Terms of All Options.

     (a) An Option shall be granted pursuant to an Agreement as either an Incentive Stock Option or a Non-Statutory Stock Option. The purchase price of each Share subject to an Option shall be determined by the Committee and set forth in the Agreement, but shall not be less than the Fair Market Value of a Share as of the date the Option is granted (except as provided in Plan Sections 9.2 and 19).

     (b) The purchase price of the Shares with respect to which an Option is exercised shall be payable in full at the time of exercise, provided that to the extent permitted by law, the Agreement may permit some or all Participants to simultaneously exercise Options and sell the Shares thereby acquired pursuant to a brokerage or similar relationship and use the proceeds from the sale as payment of the purchase price of the Shares. The purchase price may be payable in cash, by delivery or tender of Shares having a Fair Market Value as of the date the Option is exercised equal to the purchase price of the Shares being purchased pursuant to the Option, or a combination thereof, as determined by the Committee, but no fractional Shares will be issued or accepted. Provided, however, that a Participant exercising a stock option shall not be permitted to pay any portion of the purchase price with Shares if, in the opinion of the Committee, payment in such manner could have adverse financial accounting consequences for the Company.

     (c) Each Option shall be exercisable in whole or in part on the terms provided in the Agreement. In no event shall any Option be exercisable at any time after the expiration of its Term. When an Option is no longer exercisable, it shall be deemed to have lapsed or terminated.

     (d) Each Option granted to a Participant shall expire at such time as the Committee shall determine at the time of grant; provided, however, that no Option shall be exercisable later than the 10th anniversary date of its grant.

     9.2 Incentive Stock Options. In addition to the other terms and conditions applicable to all Options:

     (i) the purchase price of each Share subject to an Incentive Stock Option shall not be less than 100% of the Fair Market Value of a Share as of the date the Incentive Stock Option is granted if this limitation is necessary to qualify the Option as an Incentive Stock Option (except as provided in Plan Section 20);

     (ii) the aggregate Fair Market Value (determined as of the date the Option is granted) of the Shares with respect to which Incentive Stock Options held by an individual first become exercisable in any calendar year (under the Plan and all other incentive stock option plans of the Company and its Affiliates) shall not exceed $100,000 (or such other limit as may be required by the Code) if this limitation is necessary to qualify the Option as an Incentive Stock Option and to the extent an Option or Options granted to a Participant exceed this limit the Option or Options shall be treated as a Non-Statutory Stock Option;

     (iii) the Agreement covering an Incentive Stock Option shall contain such other terms and provisions that the Committee determines necessary to qualify this Option as an Incentive Stock Option; and

     (iv) notwithstanding any other provision of the Plan to the contrary, no Participant may receive an Incentive Stock Option under the Plan if, at the time the Award is granted, the Participant owns (after application of the rules contained in Code Section 424(d), or its successor provision), Shares possessing more than 10% of the total combined voting power of all classes of stock of the Company or its Subsidiaries, unless (i) the exercise price for that Incentive Stock Option is at least 110% of the Fair Market Value of the Shares subject to that Incentive Stock Option on the date of grant and (ii) that Option is not exercisable after the date five years from the date that Incentive Stock Option is granted.

     10.  Stock Appreciation Rights. An Award of a Stock Appreciation Right shall entitle the Participant (or a Successor or Transferee), subject to terms and conditions determined by the Committee, to receive upon exercise of the Stock Appreciation Right all or a portion of the excess of (i) the Fair Market Value of a specified number of Shares as of the date of exercise of the Stock Appreciation Right over (ii) a specified price that shall not be less than 100% of the Fair Market Value of such Shares as of the date of grant of the Stock Appreciation Right. A Stock Appreciation Right may be granted in connection with part or all of, in addition to, or completely independent of an Option or any other Award under the Plan. If issued in connection with a previously or contemporaneously granted Option, the Committee may impose a condition that exercise of a Stock Appreciation Right cancels a pro rata portion of the Option with which it is connected and vice versa. Each Stock Appreciation Right may be exercisable in whole or in part on the terms provided in the Agreement. No Stock Appreciation Right shall be exercisable at any

time after the expiration of its Term. When a Stock Appreciation Right is no longer exercisable, it shall be deemed to have lapsed or terminated. Upon exercise of a Stock Appreciation Right, payment to the Participant or a Successor or Transferee shall be made at such time or times as shall be provided in the Agreement in the form of cash, Shares or a combination of cash and Shares as determined by the Committee. The Agreement may provide for a limitation upon the amount or percentage of the total appreciation on which payment (whether in cash and/or Shares) may be made in the event of the exercise of a Stock Appreciation Right. The Term of a Stock Appreciation Right granted under the Plan shall be determined by the Committee, in its sole discretion; provided, however, that such Term shall not exceed 10 years.

     11.  Performance Units.

     11.1 Initial Award.

     (a) An Award of Performance Units under the Plan shall entitle the Participant or a Successor or Transferee to future payments of cash, Shares or a combination of cash and Shares, as determined by the Committee, based upon the achievement of pre-established performance targets. These performance targets may, but need not, include, without limitation, targets relating to one or more of the Company’s or a group’s, unit’s, Affiliate’s or an individual’s performance. The Agreement may establish that a portion of a Participant’s Award will be paid for performance that exceeds the minimum target but falls below the maximum target applicable to the Award. The Agreement shall also provide for the timing of the payment.

     (b) Following the conclusion or acceleration of each Performance Cycle, the Committee shall determine the extent to which (i) performance targets have been attained, (ii) any other terms and conditions with respect to an Award relating to the Performance Cycle have been satisfied and (iii) payment is due with respect to an Award of Performance Units.

     11.2 Acceleration and Adjustment. The Agreement may permit an acceleration of the Performance Cycle and an adjustment of performance targets and payments with respect to some or all of the Performance Units awarded to a Participant, upon the occurrence of certain events, which may, but need not include, without limitation, a Fundamental Change, a recapitalization, a change in the accounting practices of the Company, a change in the Participant’s title or employment responsibilities, the Participant’s death or retirement or, with respect to payments in Shares with respect to Performance Units, a reclassification, stock dividend, stock split or stock combination as provided in Plan Section 16. The Agreement also may provide for a limitation on the value of an Award of Performance Units that a Participant may receive.

     12.  Effective Date and Duration of the Plan.

     12.1 Effective Date. The Plan is effective as of November 6, 2000.

     12.2 Duration of the Plan. The Plan shall remain in effect until all Stock subject to it shall be distributed, all Awards have expired or lapsed, the Plan is terminated pursuant to Plan Section 15, or December 4, 2019 (the “Termination Date”); provided, however, that Awards made before the Termination Date may be exercised, vested or otherwise effectuated beyond the Termination Date unless limited in the Agreement or otherwise. No Award of an Incentive Stock Option shall be made more than 10 years after the Effective Date (or such other limit as may be required by the Code) if this limitation is necessary to qualify the Option as an Incentive Stock Option. The date and time of approval by the Committee of the granting of an Award shall be considered the date and time at which the Award is made or granted.

     13.  Plan Does Not Affect Employment Status.

     (a) Status as an eligible Employee shall not be construed as a commitment that any Award will be made under the Plan to that eligible Employee or to eligible Employees generally.

     (b) Nothing in the Plan or in any Agreement or related documents shall confer upon any Employee or Participant any right to continue in the employment of the Company or any Affiliate or constitute any contract of employment or affect any right that the Company or any Affiliate may have to change such person’s compensation, other benefits, job responsibilities, or title, or to terminate the employment of such person with or without cause.

     14.  Tax Withholding. The Company shall have the right to withhold from any cash payment under the Plan to a Participant or other person (including a Successor or a Transferee) an amount sufficient to cover any required withholding taxes. The Company shall have the right to require a Participant or other person receiving Shares under the Plan to pay the Company a cash amount sufficient to cover any required withholding taxes before actual receipt

of those Shares. In lieu of all or any part of a cash payment from a person receiving Shares under the Plan, the Committee may permit the individual to cover all or any part of the required withholdings through a reduction of the number of Shares delivered or delivery or tender return to the Company of Shares held by the Participant or other person, in each case valued in the same manner as used in computing the withholding taxes under the applicable laws.

     15.  Amendment, Modification and Termination of the Plan.

     (a) The Board may at any time and from time to time terminate, suspend or modify the Plan. Except as limited in (b) below, the Committee may at any time alter or amend any or all Agreements under the Plan to the extent permitted by law.

     (b) No termination, suspension, or modification of the Plan will materially and adversely affect any right acquired by any Participant or Successor or Transferee under an Award granted before the date of termination, suspension, or modification, unless otherwise agreed to by the Participant in the Agreement or otherwise, or required as a matter of law; but it will be conclusively presumed that any adjustment for changes in capitalization provided for in Plan Sections 11.2 or 16 does not adversely affect these rights.

     16.  Adjustment for Changes in Capitalization. In the event of any equity restructuring (within the meaning of authoritative guidance issued by the Financial Accounting Standards Board relating to stock-based compensation) that causes the per Share value of Shares to change, such as a stock dividend, stock split, spin off, rights offering, or recapitalization through a large, nonrecurring cash dividend, the Committee shall cause there to be made an equitable adjustment to (i) the number and kind of Shares that may be issued under the Plan, (ii) the limitations on the number of Shares that may be issued to an individual Participant as an Option or a Stock Appreciation Right or in the form of Restricted Stock in any calendar year or that may be issued in the form of Restricted Stock or Shares without restrictions and (iii) the number and kind of Shares or, subject to Plan Section 11.2, Performance Units, subject to and the exercise price (if applicable) of any then outstanding Awards of Options, Stock Appreciation Rights, Restricted Stock, Performance Units or any other Awards related to shares of Stock (to the extent such other Awards would not otherwise automatically adjust in the equity restructuring); provided, in each case, that with respect to Incentive Stock Options, no such adjustment shall be authorized to the extent that such adjustment would cause such options to violate Section 422(b) of the Code or any successor provision; provided further, with respect to all Awards, no such adjustment shall be authorized to the extent that such adjustment would cause the Awards to be subject to adverse tax consequences under Section 409A of the Code. In the event of any other change in corporate capitalization, such as a merger, consolidation, any reorganization (whether or not such reorganization comes within the definition of such term in Section 368 of the Code), including a Fundamental Change (subject to Plan Section 17), or any partial or complete liquidation of the Company, such equitable adjustments described in the foregoing sentence may be made as determined to be appropriate and equitable by the Committee to prevent dilution or enlargement of rights. In either case, any such adjustment shall be conclusive and binding for all purposes of the Plan. Unless otherwise determined by the Committee, the number of Shares subject to an Award shall always be a whole number. In no event shall an outstanding Option or Stock Appreciation Right be amended for the sole purpose of reducing the exercise price or grant price thereof.

     17.  Fundamental Change. In the event of a proposed Fundamental Change, the Committee may, but shall not be obligated to:

     (a) if the Fundamental Change is a merger or consolidation or statutory share exchange, make appropriate provision for the protection of the outstanding Options and Stock Appreciation Rights by the substitution of options, stock appreciation rights and appropriate voting common stock of the corporation surviving any merger or consolidation or, if appropriate, the parent corporation of the Company or such surviving corporation; or

     (b) at least ten days before the occurrence of the Fundamental Change, declare, and provide written notice to each holder of an Option or Stock Appreciation Right of the declaration, that each outstanding Option and Stock Appreciation Right, whether or not then exercisable, shall be canceled at the time of, or immediately before the occurrence of the Fundamental Change in exchange for payment to each holder of an Option or Stock Appreciation Right, within ten days after the Fundamental Change, of cash equal to (i) for each Share covered by the canceled Option, the amount, if any, by which the Fair Market Value (as defined in this Section) per Share exceeds the exercise price per Share covered by such Option or (ii) for each Stock Appreciation Right, the price determined pursuant to Section 10, except that Fair Market Value of the Shares as of the date of exercise of the Stock Appreciation Right, as used in clause (i) of Plan Section 10, shall be deemed to mean Fair Market Value for each

Share with respect to which the Stock Appreciation Right is calculated determined in the manner hereinafter referred to in this Section. At the time of the declaration provided for in the immediately preceding sentence, each Stock Appreciation Right and each Option shall immediately become exercisable in full and each person holding an Option or a Stock Appreciation Right shall have the right, during the period preceding the time of cancellation of the Option or Stock Appreciation Right, to exercise the Option as to all or any part of the Shares covered thereby or the Stock Appreciation Right in whole or in part, as the case may be. In the event of a declaration pursuant to Plan Section 17(b), each outstanding Option and Stock Appreciation Right granted pursuant to the Plan that shall not have been exercised before the Fundamental Change shall be canceled at the time of, or immediately before, the Fundamental Change, as provided in the declaration.

     Notwithstanding the foregoing, no person holding an Option or a Stock Appreciation Right shall be entitled to the payment provided for in this Section 17(b) if such Option or Stock Appreciation Right shall have terminated, expired or been cancelled. For purposes of this Section only, “Fair Market Value” per Share means the cash plus the fair market value, as determined in good faith by the Committee, of the non-cash consideration to be received per Share by the stockholders of the Company upon the occurrence of the Fundamental Change.

     18.  Prohibition on Repricing. Without the approval of the Company’s stockholders, the Committee will not reprice, adjust or amend the exercise price of any Option or the grant price of any Stock Appreciation Right previously awarded, whether through amendment, cancellation and replacement grant or any other means, except pursuant to Section 16 of the Plan in connection with an equity restructuring, or pursuant to Section 17 of the Plan in connection with a Fundamental Change, in order to prevent dilution or enlargement of the benefits, or potential benefits intended to be provided under the Plan.

     19.  Forfeitures

     (a) Forfeiture for Cause. With respect to Awards made on or after December 4, 2009, notwithstanding any other provision of the Plan or an Agreement, if the Committee finds by a majority vote that a Participant, before or after his termination of employment with the Company and its Affiliates: (i) committed a felony or a crime involving moral turpitude or committed any other act or omission involving fraud, embezzlement or any other act of dishonesty in the course of his employment by the Company or an Affiliate which conduct damaged the Company or an Affiliate; (ii) substantially and repeatedly failed to perform duties of the office held by the Participant as reasonably directed by the Company or an Affiliate; (iii) committed gross negligence or willful misconduct with respect to the Company or an Affiliate; (iv) committed a material breach of any employment agreement between the Participant and the Company or an Affiliate that is not cured within ten (10) days after receipt of written notice thereof from the Company or the Affiliate, as applicable; (v) failed, within ten (10) days after receipt by the Participant of written notice thereof from the Company or an Affiliate, to correct, cease or otherwise alter any failure to comply with instructions or other action or omission which the Board reasonably believes does or may materially or adversely affect the Company’s or an Affiliate’s business or operations; (vi) committed misconduct which is of such a serious or substantial nature that a reasonable likelihood exists that such misconduct will materially injure the reputation of the Company or an Affiliate; (vii) harassed or discriminated against the Company’s or an Affiliate’s employees, customers or vendors in violation of the Company’s policies with respect to such matters; (viii) misappropriated funds or assets of the Company or an Affiliate for personal use or willfully violated the Company policies or standards of business conduct as determined in good faith by the Board; (ix) failed, due to some action or inaction on the part of the Participant, to have immigration status that permits the Participant to maintain full-time employment with the Company or an Affiliate in the United States in compliance with all applicable immigration law; (x) disclosed trade secrets of the Company or an Affiliate, then as of the date the Committee makes its finding, any Awards awarded to the Participant that have not been exercised by the Participant (including all Awards that have not yet vested) will be forfeited to the Company. The findings and decision of the Committee or the Board, if applicable, with respect to such matter, including those regarding the acts of the Participant and the damage done to the Company, will be final for all purposes. No decision of the Committee, however, will affect the finality of the discharge of the individual by the Company or an Affiliate.

     (b) Forfeiture Events . With respect to Awards made on or after December 4, 2009, the Committee may specify in an Agreement that the Participant’s rights, payments, and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture, or recoupment upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Such events may include, but shall not be limited to, termination of employment for cause, termination of employment for any other reason, violation of material policies of the Company and its Affiliates, breach of noncompetition, confidentiality, or other

restrictive covenants that may apply to the Participant, or other conduct by the Participant that is detrimental to the business or reputation of the Company and its Affiliates.

     20.  Corporate Mergers, Acquisitions, Etc. The Committee may also grant Options, Stock Appreciation Rights, Restricted Stock or other Awards under the Plan in substitution for, or in connection with the assumption of, existing options, stock appreciation rights, restricted stock or other award granted, awarded or issued by another corporation and assumed or otherwise agreed to be provided for by the Company pursuant to or by reason of a transaction involving a corporate merger, consolidation, acquisition of property or stock, separation, reorganization or liquidation to which the Company or a Subsidiary is a party. The terms and conditions of the substitute Awards may vary from the terms and conditions set forth in the Plan to the extent as the Board at the time of the grant may deem appropriate to conform, in whole or in part, to the provisions of the awards in substitution for which they are granted.

     21.  Unfunded Plan. The Plan shall be unfunded and the Company shall not be required to segregate any assets that may at any time be represented by Awards under the Plan. Neither the Company, its Affiliates, the Committee, nor the Board of Directors shall be deemed to be a trustee of any amounts to be paid under the Plan nor shall anything contained in the Plan or any action taken pursuant to its provisions create or be construed to create a fiduciary relationship between the Company and/or its Affiliates, and a Participant or Successor or Transferee. To the extent any person acquires a right to receive an Award under the Plan, this right shall be no greater than the right of an unsecured general creditor of the Company.

     22.  Limits of Liability.

     (a) Any liability of the Company to any Participant with respect to an Award shall be based solely upon contractual obligations created by the Plan and the Award Agreement.

     (b) Except as may be required by law, neither the Company nor any member of the Board of Directors or of the Committee, nor any other person participating in any determination of any question under the Plan, or in the interpretation, administration or application of the Plan, shall have any liability to any party for any action taken, or not taken, in good faith under the Plan.

     23.  Compliance with Applicable Legal Requirements. No certificate for Shares distributable pursuant to the Plan shall be issued and delivered unless the issuance of the certificate complies with all applicable legal requirements including, without limitation, compliance with the provisions of applicable state securities laws, the Securities Act of 1933, as amended and in effect from time to time or any successor statute, the Exchange Act and the requirements of the exchanges on which the Company’s Shares may, at the time, be listed.

     24.  Deferrals and Settlements. The Committee may require or permit Participants to elect to defer the issuance of Shares or the settlement of Awards in cash under such rules and procedures as it may establish under the Plan. It may also provide that deferred settlements include the payment or crediting of interest on the deferral amounts.

     25.  Other Benefit and Compensation Programs. Payments and other benefits received by a Participant under an Award made pursuant to the Plan shall not be deemed a part of a Participant’s regular, recurring compensation for purposes of the termination, indemnity or severance pay laws of any country and shall not be included in, nor have any effect on, the determination of benefits under any other employee benefit plan, contract or similar arrangement provided by the Company or an Affiliate unless expressly so provided by such other plan, contract or arrangement, or unless the Committee expressly determines that an Award or portion of an Award should be included to accurately reflect competitive compensation practices or to recognize that an Award has been made in lieu of a portion of competitive cash compensation.

     26.  Beneficiary Upon Participant’s Death. To the extent that the transfer of a Participant’s Award at his or her death is permitted under an Agreement, a Participant’s Award shall be transferable at death to the estate or to the person who acquires the right to succeed to the Award by bequest or inheritance.

     27.  Requirements of Law.

     (a) To the extent that federal laws do not otherwise control, the Plan and all determinations made and actions taken pursuant to the Plan shall be governed by the laws of the State of Minnesota without regard to its conflicts-of-law principles and shall be construed accordingly.

     (b) If any provision of the Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not effect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid provision had not been included.

Exhibit 10(b)

DIGI INTERNATIONAL INC.
EMPLOYEE STOCK PURCHASE PLAN
AS AMENDED AND RESTATED AS OF DECEMBER 4, 2009

     1. PURPOSE AND SCOPE OF PLAN. The purpose of this Digi International Inc. Employee Stock Purchase Plan (the “Plan”) is to provide the employees of Digi International Inc. (the “Company”) with an opportunity to acquire a proprietary interest in the Company through the purchase of its Common Stock and, thus, to develop a stronger incentive to work for the continued success of the Company. The Plan is intended to be an “employee stock purchase plan” within the meaning of Section 423(b) of the Internal Revenue Code of 1986, as amended, and shall be interpreted and administered in a manner consistent with such intent.

     2. DEFINITIONS.

     2.1. The terms defined in this section are used (and capitalized) elsewhere in this Plan:

     (a) “Affiliate” means any corporation that is a “parent corporation” or “subsidiary corporation” of the Company, as defined in Sections 424(e) and 424(f) of the Code or any successor provision, and whose participation in the Plan has been approved by the Board of Directors.

     (b) “Board of Directors” means the Board of Directors of the Company.

     (c) “Code” means the Internal Revenue Code of 1986, as amended from time to time.

     (d) “Committee” means three or more Disinterested Persons designated by the Board of Directors to administer the Plan under Section 13.

     (f) “Company” means Digi International Inc.

     (h) “Disinterested Persons” means a member of the Board of Directors who is considered a disinterested person within the meaning of Exchange Act Rule 16b-3 or any successor definition.

     (i) “Eligible Employee” means any employee of the Company or an Affiliate who has been employed for at least 90 days and whose customary employment is at least 20 hours per week; provided, however, that “Eligible Employee” shall not include any person who would be deemed for purposes of Section 423(b)(3) of the Code, to own stock possessing 5% or more of the total combined voting power or value of all classes of stock of the Company.

     (j) “Exchange Act” means the Securities Exchange Act of 1934, as amended from time to time.

     (k) “Fair Market Value” of a share of Common Stock as of any date means, if the Company’s Common Stock is listed on a national securities exchange or traded in the national market system, the mean between the high and low sale prices for such Common Stock on such exchange or market on said date, or, if no sale has been made on such exchange or market on said date, on the last preceding day on which any sale shall have been made. If such determination of Fair Market Value is not consistent with the then current regulations of the Secretary of the Treasury applicable to plans intended to qualify as an “employee stock purchase plan” within the meaning of Section 423(b) of the Code, however, Fair Market Value shall be determined in accordance with such regulations. The determination of Fair Market Value shall be subject to adjustment as provided in Section 14.

     (l) “Participant” means an Eligible Employee who has elected to participate in the Plan in the manner set forth in Section 4.

     (m) “Plan” means this Digi International Inc. Employee Stock Purchase Plan, as amended from time to time.

     (n) “Purchase Period” means each quarter of the Company’s fiscal year. The first Purchase Period will be the quarter that starts April 1, 1996 and ends June 30, 1996.

     (o) “Recordkeeping Account” means the account maintained in the books and records of the Company recording the amount withheld from each Participant through payroll deductions made under the Plan.

     (p) “Share” means a share of Common Stock.

     3. SCOPE OF THE PLAN. Shares of Common Stock may be sold by the Company to Eligible Employees commencing April 1, 1996, as hereinafter provided, but not more than 2,000,000 shares of Common Stock (subject to adjustment as provided in Section 14) shall be sold to Eligible Employees pursuant to this Plan. All sales of Common Stock pursuant to this Plan shall be subject to the same terms, conditions, rights and privileges. The shares of Common Stock delivered by the Company pursuant to this Plan may be acquired shares having the status of any combination of authorized but unissued shares, newly issued shares, or treasury shares.

     4. ELIGIBILITY AND PARTICIPATION. To be eligible to participate in the Plan for a given Purchase Period, an employee must be an Eligible Employee on the first day of such Purchase Period. An Eligible Employee may elect to participate in the Plan by filing an enrollment form with the Company before the first day of such Purchase Period that authorizes regular payroll deductions from Compensation beginning with the first payday in such Purchase Period and continuing until the Eligible Employee withdraws from the Plan, modifies his or her authorization, or ceases to be an Eligible Employee, as hereinafter provided.

     5. AMOUNT OF COMMON STOCK EACH ELIGIBLE EMPLOYEE MAY PURCHASE.

     5.1. Subject to the provisions of the Plan, each Eligible Employee shall be offered the right to purchase on the last day of the Purchase Period the number of shares of Common Stock (including fractional shares) that can be purchased at the price specified in Section 5.2 with the entire credit balance in the Participant’s Recordkeeping Account; provided, however, that the Fair Market Value (determined on the first day of any Purchase Period) of shares of Common Stock that may be purchased by a Participant during such Purchase Period shall not exceed the excess, if any, of (i) $25,000 over (ii) the Fair Market Value (determined on the first day of the relevant Purchase Period) of shares of Common Stock previously acquired by the Participant in any prior Purchase Period during such calendar year. Notwithstanding the foregoing, no Eligible Employee shall be granted an option to acquire shares of Common Stock under this Plan which permits the Eligible Employee’s rights to purchase shares of Common Stock under this Plan and all employee stock purchase plans of the Company and the Affiliates to accrue at a rate which exceeds $25,000 of Fair Market Value (determined at the time such option is granted) for each calendar year in which such option is outstanding at any time. If the purchases by all Participants would otherwise cause the aggregate number of shares of Common Stock to be sold under the Plan to exceed the number specified in Section 3, however, each Participant shall be allocated at a ratable portion of the maximum number of shares of Common Stock which may be sold.

     5.2. The purchase price of each share of Common Stock sold pursuant to this Plan will be the lesser of (a) or (b) below: (a) 85% of the Fair Market Value of such share on the first day of the Purchase Period. (b) 85% of the Fair Market Value of such share on the last day of the Purchase Period.

     6. METHOD OF PARTICIPATION.

     6.1. The Company shall give notice to each Eligible Employee of the opportunity to purchase shares of Common Stock pursuant to this Plan and the terms and conditions for such offering. Such notice is subject to revision by the Company at any time prior to the date of purchase of such shares. The Company contemplates that for tax purposes the first day of a Purchase Period will be the date of the offering of such shares.

     6.2. Each Eligible Employee who desires to participate in the Plan for a Purchase Period shall signify his or her election to do so by signing an election form developed by the Committee. An Eligible Employee may elect to have any whole percent of Compensation withheld, but not exceeding ten percent (10%) per pay period. An election to participate in the Plan and to authorize payroll deductions as described herein must be made before the first day of the Purchase Period to which it relates and shall remain in effect unless and until such Participant withdraws from this Plan, modifies his or her authorization, or terminates his or her employment with the Company, as hereinafter provided.

     6.3. Any Eligible Employee who does not make a timely election as provided in Section 6.2, shall be deemed to have elected not to participate in the Plan. Such election shall be irrevocable for such Purchase Period.

     7. RECORDKEEPING ACCOUNT.

     7.1. The Company shall maintain a Recordkeeping Account for each Participant. Payroll deductions pursuant to Section 6 will be credited to such Recordkeeping Accounts on each payday.

     7.2. No interest will be credited to a Participant’s Recordkeeping Account.

     7.3. The Recordkeeping Account is established solely for accounting purposes, and all amounts credited to the Recordkeeping Account will remain part of the general assets of the Company.

     7.4. A Participant may not make any separate cash payment into the Recordkeeping Account.

     8. RIGHT TO ADJUST PARTICIPATION OR TO WITHDRAW.

     8.1. A Participant may, at any time during a Purchase Period, direct the Company to make no further deductions from his or her Compensation or to adjust the amount of such deductions. Upon either of such actions, future payroll deductions with respect to such Participant shall cease or be adjusted in accordance with the Participant’s direction.

     8.2. Any Participant who stops payroll deductions may not thereafter resume payroll deductions during such Purchase Period.

     8.3. At any time before the end of a Purchase Period, any Participant may also withdraw from the Plan. In such event, all future payroll deductions shall cease and the entire credit balance in the Participant’s Recordkeeping Account will be paid to the Participant, without interest, in cash within 15 days. A Participant who withdraws from the Plan will not be eligible to reenter the Plan until the next succeeding Purchase Period.

     8.4. Notification of a Participant’s election to adjust or terminate deductions, or to withdraw from the Plan, shall be made by the filing of an appropriate notice to such effect with the Company.

     9. TERMINATION OF EMPLOYMENT. If the employment of a Participant is terminated for any reason, including death, disability, or retirement, the entire balance in the Participant’s Recordkeeping Account will be applied to the purchase of shares as provided in Section 10.1 as of the last day of the Purchase Period in which the Participant’s employment terminated; except that if such Participant so requests prior to the last day of such Purchase Period, the Company shall refund in cash within 15 days all amounts credited to his or her Recordkeeping Account.

     10. PURCHASE OF SHARES.

     10.1. As of the last day of the Purchase Period, the entire credit balance in each Participant’s Recordkeeping Account will be used to purchase shares (including fractional shares) of Common Stock (subject to the limitations of Section 5) unless the Participant has filed an appropriate form with the Company in advance of that date (which either elects to purchase a specified number of shares which is less than the number described above or elects to receive the entire credit balance in cash). Any amount in a Participant’s Recordkeeping Account that is not used to purchase shares pursuant to this Section 10.1 will be refunded to the Participant.

     10.2. Shares of Common Stock acquired by each Participant shall be held in a general account maintained for the benefit of all Participants.

     10.3. Certificates for the number of whole shares of Common Stock, determined as aforesaid, purchased by each Participant shall be issued and delivered to him or her only upon request of the Participant or his or her representative directed to the Company. No Certificates for fractional shares will be issued. Instead, Participants will receive a cash distribution representing any fractional shares.

     10.4. Dividends with respect to a Participant’s shares held in the general account will, at the election of the Participant, either be paid to the Participant in cash or reinvested in additional shares of Common Stock. If a Participant fails to make such an election, all dividends with respect to the Participant’s shares held in the general account will automatically be reinvested to purchase additional shares of Common Stock.

     10.5. Each Participant will be entitled to vote all shares held for the benefit of such Participant in the general account.

     11. RIGHTS AS A STOCKHOLDER. A Participant shall not be entitled to any of the rights or privileges of a stockholder of the Company with respect to such shares, including the right to receive any dividends which may be

declared by the Company, until (i) he or she actually has paid the purchase price for such shares and (ii) either the shares have been credited to his or her account or certificates have been issued to him or her, both as provided in Section 10.

     12. RIGHTS NOT TRANSFERABLE. A Participant’s rights under this Plan are exercisable only by the Participant during his or her lifetime, and may not be sold, pledged, assigned or transferred in any manner other than by will or the laws of descent and distribution. Any attempt to sell, pledge, assign or transfer the same shall be null and void and without effect. The amounts credited to a Recordkeeping Account may not be assigned, transferred, pledged or hypothecated in any way, and any attempted assignment, transfer, pledge, hypothecation or other disposition of such amounts will be null and void and without effect.

     13. ADMINISTRATION OF THE PLAN. This Plan shall be administered by the Committee, which is authorized to make such uniform rules as may be necessary to carry out its provisions. The Committee shall determine any questions arising in the administration, interpretation and application of this Plan, and all such determinations shall be conclusive and binding on all parties.

     14. ADJUSTMENT FOR CHANGES IN CAPITALIZATION. In the event of any equity restructuring (within the meaning of authoritative guidance issued by the Financial Accounting Standards Board relating to stock-based compensation) that causes the per Share value of Shares to change, such as a stock dividend, stock split, spin off, rights offering, or recapitalization through a large, nonrecurring cash dividend, the Committee shall cause there to be made an equitable adjustment to the number, class and purchase price of Shares that may be purchased under the Plan. In the event of any other change in corporate capitalization, such as a merger, consolidation, any reorganization (whether or not such reorganization comes within the definition of such term in Section 368 of the Code), or any partial or complete liquidation of the Company, such equitable adjustments described in the foregoing sentence may be made as determined to be appropriate and equitable by the Committee to prevent dilution or enlargement of rights. In either case, any such adjustment shall be conclusive and binding for all purposes of the Plan.

     15. REGISTRATION OF CERTIFICATES. Stock certificates will be registered in the name of the Participant, or jointly in the name of the Participant and another person, as the Participant may direct on an appropriate form.

     16. AMENDMENT OF PLAN. The Board of Directors may at any time amend this Plan in any respect which shall not adversely affect the rights of Participants pursuant to shares previously acquired under the Plan, except that, without stockholder approval, no amendment shall be made (i) to increase the number of shares to be reserved under this Plan, (ii) to decrease the minimum purchase price, (iii) to withdraw the administration of this Plan from the Committee, or (iv) to change the definition of employees eligible to participate in the Plan.

     17. EFFECTIVE DATE OF PLAN. This Plan shall consist of an offering commencing April 1, 1996, and ending June 30, 1996, and continuing on a quarterly basis thereafter. All rights of Participants in any offering hereunder shall terminate at the earlier of (i) the day that Participants become entitled to purchase a number of shares of Common Stock equal to or greater than the number of shares remaining available for purchase or (ii) at any time, at the discretion of the Board of Directors, after 30 days’ notice has been given to all Participants. Upon termination of this Plan, shares of Common Stock shall be issued to Participants in accordance with Section 10, and cash, if any, remaining in the Participant’s Recordkeeping Accounts shall be refunded to them, as if the Plan were terminated at the end of a Purchase Period.

     18. GOVERNMENTAL REGULATIONS AND LISTING. All rights granted or to be granted to Eligible Employees under this Plan are expressly subject to all applicable laws and regulations and to the approval of all governmental authorities required in connection with the authorization, issuance, sale or transfer of the shares of Common Stock reserved for this Plan, including, without limitation, there being a current registration statement of the Company under the Securities Act of 1933, as amended, covering the shares of Common Stock purchasable on the last day of the Purchase Period applicable to such shares, and if such a registration statement shall not then be effective, the term of such Purchase Period shall be extended until the first business day after the effective date of such a registration statement, or post-effective amendment thereto. If applicable, all such rights hereunder are also similarly subject to effectiveness of an appropriate listing application to a national securities exchange or a national market system, covering the shares of Common Stock under the Plan upon official notice of issuance.

     19. MISCELLANEOUS.

     19.1. This Plan shall not be deemed to constitute a contract of employment between the Company and any Participant, nor shall it interfere with the right of the Company to terminate any Participant and treat him or her without regard to the effect which such treatment might have upon him or her under this Plan.

     19.2. Wherever appropriate as used herein, the masculine gender may be read as the feminine gender, the feminine gender may be read as the masculine gender, the singular may be read as the plural and the plural may be read as the singular.

     19.3. The Plan, and all agreements hereunder, shall be construed in accordance with and governed by the laws of the State of Minnesota.

     19.4. Delivery of shares of Common Stock or of cash pursuant to this Plan shall be subject to any required withholding taxes. A person entitled to receive shares of Common Stock may, as a condition precedent to receiving such shares, be required to pay the Company a cash amount equal to the amount of any required withholdings.

          These are the terms and conditions applicable to the NONSTATUTORY STOCK OPTION AGREEMENT between Digi International Inc., a Delaware corporation (the “Company”), and the optionee (the “Optionee”) listed on the cover page hereof (the “Cover Page”) effective as of the date of grant. The Cover Page together with these terms and conditions of Nonstatutory Stock Option Agreement constitute the “Nonstatutory Stock Option Agreement.”

          WHEREAS, the Company desires to carry out the purposes of its Digi International Inc. 2000 Omnibus Stock Plan as amended from time to time (the “Plan”), by affording the Optionee an opportunity to purchase Common Stock of the Company, par value $.01 per share (the “Common Shares”), according to the terms set forth herein and on the Cover Page;

          NOW THEREFORE, the Company hereby grants this Option to the Optionee under the terms and conditions as follows.

           1. Grant of Option. Subject to the terms of the Plan, the Company hereby grants to the Optionee the right and option (the “Option”) to purchase the number of Common Shares specified on the Cover Page, on the terms and conditions hereinafter set forth. The Option is not intended by the Company to be an “incentive stock option” within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”).

           2. Purchase Price. The purchase price of each of the Common Shares subject to the Option shall be the exercise price per share specified on the Cover Page, which price has been specified in accordance with the Plan and shall not be less than 100% of the Fair Market Value (as defined in paragraph 2.1(l) of the Plan) of a common share as of the date of grant.

           3. Option Period.

          (a) Subject to the provisions of paragraphs 5(a), 5(b), 6(a) and 6(b) hereof, the Option shall become exercisable as to the number of shares and on the dates specified in the exercise schedule on the Cover Page. The exercise schedule shall be cumulative; thus, to the extent the Option has not already been exercised and has not expired, terminated or been canceled, the Optionee may at any time, and from time to time, purchase all or any portion of the Common Shares then purchasable under the exercise schedule.

          (b) The Option and all rights to purchase shares thereunder shall cease on the earliest of:

     (i) the expiration date specified on the Cover Page (which date shall not be more than ten years after the date of this Nonstatutory Stock Option Agreement);

     (ii) the expiration of the period after the termination of the Optionee’s employment (as defined in paragraph 5 of the Plan) within which the Option is exercisable as specified in paragraph 5(a) or 5(b), whichever is applicable; or

     (iii) the date, if any, fixed for cancellation pursuant to paragraph 6(b) hereof.

Notwithstanding any other provision in this Nonstatutory Stock Option Agreement, in no event may anyone exercise the Option, in whole or in part, after its original expiration date.

           4. Manner of Exercising Option.

          Subject to the terms and conditions of this Nonstatutory Stock Option Agreement, the Option may be exercised online with E*Trade at www.etrade.com/stockplans or by such other means as the Committee shall approve. In accordance with present practice, when your stock option is granted, a letter or email will be sent to you from E*Trade with instructions on how to activate your account with E*Trade so that you can view and exercise your stock options online. If you are a director or officer of the Company, then you must contact E*Trade Executive Support at 1-800-775-2793 in order to exercise your options.

           5. Exercisability of Option After Termination of Employment.

          (a) During the lifetime of the Optionee, the Option may be exercised only while the Optionee is employed (as defined in paragraph 5 of the Plan) by the Company or a parent or subsidiary thereof, and only if the Optionee has been continuously so employed since the date of this Nonstatutory Stock Option Agreement, except that:

     (i) if the Optionee is not an Outside Director (as defined in paragraph 2.1(t) of the Plan), the Option shall continue to be exercisable for three months after termination of the Optionee’s employment for any reason other than death or disability, but only to the extent that the Option was exercisable immediately prior to the Optionee’s termination of employment;

     (ii) if the Optionee is not an Outside Director, in the event the Optionee is disabled (within the meaning of Section 22(e)(3) of the Code) while employed, the Optionee or his or her legal representative may exercise the Option (to the extent specified in paragraph 6(a) of this Nonstatutory Stock Option Agreement) within one year after the termination of the Optionee’s employment because of such disability;

     (iii) if the Optionee is not an Outside Director and if the Optionee dies while employed, or within three months after his or her termination of employment, then (notwithstanding paragraph 5(a)(i) of this Nonstatutory Stock Option Agreement) heirs or legatees of the Optionee’s estate or the person who acquired the right to exercise the Option by bequest or inheritance may exercise the Option (to the extent specified in paragraph 6(a)) within one year after the death of the Optionee;

     (iv) if the Optionee is an Outside Director, the Option shall continue to be exercisable after the Optionee’s employment ends for the remaining term of the Option, but shall be exercisable only to the extent that the Option was exercisable immediately prior to the end of Optionee’s employment, except that if the Optionee’s employment ends because of death or disability, or the Optionee dies within three months of his or her employment ending, the Option, whether or not previously exercisable, shall become exercisable to the extent specified in paragraph 6(a) of this Nonstatutory Stock Option Agreement and shall continue to be exercisable after the Optionee’s employment ends for the remaining term of the Option; and

     (v) if the Optionee’s employment terminates after a declaration pursuant to paragraph 6(b) of this Nonstatutory Stock Option Agreement, the Optionee may exercise the Option at any time permitted by such declaration.

If, during the term of the Option, the Optionee’s status changes to or from that of an Outside Director, the provisions of this paragraph 5(a) shall be applied to the Optionee based on the Optionee’s status as of the date the Option was granted.

          (b) Neither the transfer of the Optionee between any combination of the Company, its parent and any subsidiary of the Company, nor a leave of absence granted to the Optionee and approved by the Committee, shall be deemed a termination of employment. The terms “parent” and “subsidiary” as used herein shall have the meaning ascribed to “parent corporation” and “subsidiary corporation,” respectively, in Sections 424(e) and (f) (or successor provisions) of the Code.

           6. Acceleration of Option.

          (a) Disability or Death . If paragraph 5(a)(ii), 5(a)(iii) or the exception clause of paragraph 5(a)(iv) of this Nonstatutory Stock Option Agreement is applicable, the Option, whether or not previously exercisable, shall become immediately exercisable in full if the Optionee shall have been employed continuously by the Company or a parent or subsidiary thereof between the date the Option was granted and the date of such disability or, in the event of death, a date not more than three months prior to such death.

          (b) Dissolution, Liquidation, Merger . In the event of (i) a proposed merger or consolidation of the Company with or into any other corporation, regardless of whether the Company is the surviving corporation, unless appropriate provision shall have been made for the protection of the Option by the substitution, in lieu of the Option, of an option to purchase appropriate voting common stock (the “Survivor’s Stock”) of the corporation surviving any such merger or consolidation or, if appropriate, the parent corporation of the Company or such surviving corporation, or, alternatively, by the delivery of a number of shares of the Survivor’s Stock which has a Fair Market Value as of the effective date of such merger or consolidation equal to the product of (A) the excess of (x) the Event Proceeds per Common Share (as hereinafter defined) covered by the Option as of such effective date, over (y) the Option exercise price per Common Share, times (B) the number of Common Shares covered by the Option, or (ii) the proposed dissolution or liquidation of the Company (such merger, consolidation, dissolution or liquidation being herein called an “Event”), the Committee shall declare, at least ten days prior to the actual effective date of an Event, and provide written notice to the Optionee of the declaration, that the Option, whether or not then exercisable, shall be canceled at the time of, or immediately prior to the occurrence of, the Event (unless it shall have been exercised prior to the occurrence of the Event) in exchange for payment to the Optionee, within ten days after the Event, of cash equal to the amount (if any), for each Common Share covered by the canceled Option, by which the Event Proceeds per Common Share (as hereinafter defined) exceeds the exercise price per Common Share covered by the Option. At the time of the declaration provided for in the immediately preceding sentence, the Option shall immediately become exercisable in full and the Optionee shall have the right, during the period preceding the time of cancellation of the Option, to exercise the Option as to all or any part of the Common Shares covered thereby. The Option, to the extent it shall not have been exercised prior to the Event, shall be canceled at the time of, or immediately prior to, the Event, as provided in the declaration, and this Plan shall terminate at the time of such cancellation, subject to the payment obligations of the Company provided in this paragraph 6(b). For purposes of this paragraph, “Event Proceeds per Common Share” shall mean the cash plus the fair market value, as determined in good faith by the Committee, of the non-cash consideration to be received per Common Share by the stockholders of the Company upon the occurrence of the Event.

           7. Limitation on Transfer. During the lifetime of the Optionee, only the Optionee or his or her guardian or legal representative may exercise the Option. The Optionee shall not assign or transfer the Option otherwise than by will or the laws of descent and distribution, and the Option shall not be subject to pledge, hypothecation, execution, attachment or similar process. Any attempt to assign, transfer, pledge, hypothecate or otherwise dispose of the Option contrary to the provisions hereof, and the levy of any attachment or similar process upon the Option, shall be null and void.

           8. Stockholder Rights Before Exercise. The Optionee shall have none of the rights of a stockholder of the Company with respect to any share subject to the Option until the share is actually issued to him or her upon exercise of the Option.

           9. Adjustment For Changes in Capitalization. The Option is subject to adjustment for changes in capitalization as provided in paragraph 16 of the Plan.

           10. Tax Withholding. The parties hereto recognize that the Company or a parent or subsidiary thereof may be obligated to withhold federal and state income taxes and social security or other taxes upon the Optionee’s exercise of the Option. The Optionee agrees that, at the time he or she exercises the Option, if the Company or a parent or subsidiary thereof is required to withhold such taxes, he or she will promptly pay in cash upon demand to the Company, or the parent or subsidiary having such obligation, such amounts as shall be necessary to satisfy such obligation; provided, however, that in lieu of all or any part of such a cash payment, the Committee may, but shall not be required to, (or, in the case of an Optionee who is an Outside Director (as defined in the Plan), the Committee shall) permit the Optionee to elect to cover all or any part of the required withholdings through a reduction of the number of

Common Shares delivered to the Optionee or through a subsequent return to the Company of shares delivered to the Optionee.

           11. Interpretation of this Nonstatutory Stock Option Agreement. All decisions and interpretations made by the Committee with regard to any question arising hereunder or under the Plan shall be binding and conclusive upon the Company and the Optionee. In the event that there is any inconsistency between the provisions of this Nonstatutory Stock Option Agreement and the Plan, the provisions of the Plan shall govern.

           12. Discontinuance of Employment. This Nonstatutory Stock Option Agreement shall not give the Optionee a right to continued employment with the Company or any parent or subsidiary thereof, and the Company or any such parent or subsidiary thereof employing the Optionee may terminate his or her employment and otherwise deal with the Optionee without regard to the effect it may have upon him or her under this Nonstatutory Stock Option Agreement.

           13. General. The Company shall at all times during the term of this Option reserve and keep available such number of Common Shares as will be sufficient to satisfy the requirements of this Nonstatutory Stock Option Agreement. This Nonstatutory Stock Option Agreement shall be binding in all respects on the Optionee’s heirs, representatives, successors and assigns. This Nonstatutory Stock Option Agreement is entered into under the laws of the State of Minnesota and shall be construed and interpreted thereunder.

Certain of the options may include an addendum regarding acceleration of vesting upon a change in control,
which reads substantially similar to the following:
