RADIUS INC. 1995 STOCK OPTION PLAN As Adopted December 20, 1995 1. PURPOSE. The purpose of the Plan is to provide incentives to attract, retain and motivate eligible persons whose present and potential contributions are important to the success of the Company, its Parent, Subsidiaries and Affiliates, by offering them an opportunity to participate in the Company's future performance through awards of stock options. Capitalized terms not defined in the text are defined in Section 19. 2. SHARES SUBJECT TO THE PLAN. 2.1 NUMBER OF SHARES AVAILABLE. Subject to Sections 2.2 and 14, the total number of Shares reserved and available for grant and issuance pursuant to Awards under the Plan shall be Shares, consisting of 850,000 shares, plus the total number of shares authorized for issuance, but not issued or subject to outstanding options, under the Company's 1986 Stock Option Plan (the "Prior Plan") as of the date of shareholder approval of this Plan. Any shares issuable upon exercise of options granted pursuant to the Prior Plan that expire or become unexercisable for any reason after the date of shareholder approval of this Plan without having been exercised in full, shall no longer be available for distribution under the Prior Plan, but shall be available for distribution under this Plan. Subject to Sections 2.2 and 14, Shares shall again be available for grant and issuance in connection with future Awards under the Plan if such Shares cease to be subject to an Award for any reason other than the exercise of such Award. 2.2 ADJUSTMENT OF SHARES. In the event that the number of outstanding Shares is changed by a stock dividend, recapitalization, stock split, reverse stock split, subdivision, combination, reclassification or similar change in the capital structure of the Company without consideration, then (a) the number of Shares reserved for issuance under the Plan and (b) the Exercise Prices of and number of Shares subject to outstanding Awards shall be proportionately adjusted, subject to any required action by the Board or the shareholders of the Company and compliance with applicable securities laws; PROVIDED, HOWEVER, that fractions of a Share shall not be issued but shall either be paid in cash at Fair Market Value or shall be rounded up to the nearest Share, as determined by the Committee. 3. ELIGIBILITY. ISOs (as defined in Section 5 below) may be granted only to employees (including officers and directors who are also employees) of the Company or of a Parent or Subsidiary of the Company. NQSOs (as defined in Section 5 below) may be granted to employees, officers, directors, consultants, independent contractors and advisors of the Company or any Parent, Subsidiary or Affiliate of the Company; PROVIDED such consultants, contractors and advisors render bona fide services not in connection with the offer and sale of securities in a capital-raising transaction. A person may be granted more than one Award under the Plan. No "Named Executive Officer" (as that term is defined in Item 402(a)(3) of Regulation S-K promulgated under the Exchange Act) shall be eligible to receive more than 1,000,000 shares at any time during the term of this Plan pursuant to the grant of Awards hereunder. 4. ADMINISTRATION. 4.1 COMMITTEE AUTHORITY. The Plan shall be administered by the Committee. Subject to the general purposes, terms and conditions of the Plan, the Committee shall have full power to implement and carry out the Plan. The Committee shall have the authority to: (a) construe and interpret the Plan, any Stock Option Agreement and any other agreement or document executed pursuant to the Plan; (b) prescribe, amend and rescind rules and regulations relating to the Plan; (c) select persons to receive Awards; (d) determine the form and terms of Awards; (e) determine the number of Shares subject to Awards; (f) determine whether Awards will be granted in replacement of, or as alternatives to, other Awards under the Plan or any other incentive or compensation plan of the Company or any Parent, Subsidiary or Affiliate of the Company; (g) grant waivers of Plan or Award conditions; (h) determine the vesting and exercisability of Awards; (i) correct any defect, supply any omission, or reconcile any inconsistency in the Plan, any Award or any Stock Option Agreement; (j) determine the disposition of Awards in the event of a Participant's divorce or dissolution of marriage; and (k) make all other determinations necessary or advisable for the administration of the Plan. 4.2 COMMITTEE DISCRETION. Any determination made by the Committee with respect to any Award shall be made in its sole discretion at the time of grant of the Award or, unless in contravention of any express term of the Plan or Award, at any later time, and such determination shall be final and binding on the Company and all persons having an interest in any Award under the Plan. The Committee may delegate to one or more officers of the Company the authority to grant an Award under the Plan to Participants who are not Insiders of the Company. 4.3 EXCHANGE ACT REQUIREMENTS. If two or more members of the Board are Outside Directors, the Committee shall be comprised of at least two members of the Board, all of whom are Outside Directors and Disinterested Persons. The Company will take appropriate steps to comply with the disinterested director requirements of Section 16(b) of the Exchange Act, including but not limited to, the appointment by the Board of a Committee consisting of not less than two persons (who are members of the Board), each of whom is a Disinterested Person. It is the intent of the Company that the Plan and Awards hereunder satisfy and be interpreted in a manner, that, in the case of Participants who are or may be Insiders, satisfies the applicable requirements of Rule 16b-3 (or its successor) of the Exchange Act. If any provision of the Plan or of any Award would otherwise conflict with the intent expressed in this Section 4.3, that provision to the extent possible shall be interpreted and deemed amended so as to avoid such conflict. 5. STOCK OPTIONS. The Committee may grant Awards to eligible persons and shall determine whether such Awards shall be Incentive Stock Options within the meaning of the Code ("ISOs") or Nonqualified Stock Options ("NQSOs"), the number of Shares subject to the Award, the Exercise Price of the Award, the period during which the Award may be exercised, and all other terms and conditions of the Award, subject to the following: 5.1 FORM OF OPTION GRANT. Each Award granted under the Plan shall be evidenced by a Stock Option Agreement which shall expressly identify the Award as an ISO or NQSO, and be in such form and -2- contain such provisions (which need not be the same for each Participant) as the Committee shall from time to time approve, and which shall comply with and be subject to the terms and conditions of the Plan. 5.2 DATE OF GRANT. The date of grant of an Award shall be the date on which the Committee makes the determination to grant such Award, unless otherwise specified by the Committee. The Stock Option Agreement and a copy of the Plan will be delivered to the Participant within a reasonable time after the granting of the Award. 5.3 EXERCISE PERIOD. Awards shall be exercisable within the times or upon the events determined by the Committee as set forth in the Stock Option Agreement; PROVIDED, HOWEVER, that no Award shall be exercisable after the expiration of ten (10) years from the date the Award is granted; and PROVIDED FURTHER that no ISO granted to a person who directly or by attribution owns more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary of the Company ("TEN PERCENT SHAREHOLDER") shall be exercisable after the expiration of five (5) years from the date the Award is granted. The Committee also may provide for Awards to become exercisable at one time or from time to time, periodically or otherwise, in such number or percentage as the Committee determines. 5.4 EXERCISE PRICE. The Exercise Price shall be determined by the Committee when the Award is granted and shall be not less than 50% of the Fair Market Value of the Shares on the date of grant; PROVIDED, that (i) the Exercise Price of an ISO shall be not less than 100% of the Fair Market Value of the Shares on the date of grant and (ii) the Exercise Price of any ISO granted to a Ten Percent Shareholder shall not be less than 110% of the Fair Market Value of the Shares on the date of grant. Payment for the Shares purchased may be made in accordance with Section 6 of the Plan. 5.5 METHOD OF EXERCISE. Awards may be exercised only by delivery to the Company of a written exercise agreement (the "EXERCISE AGREEMENT") in a form approved by the Committee (which need not be the same for each Participant), stating the number of Shares being purchased, the restrictions imposed on the Shares, if any, and such representations and agreements regarding Participant's investment intent and access to information and other matters, if any, as may be required or desirable by the Company to comply with applicable securities laws, together with payment in full of the Exercise Price for the number of Shares being purchased. 5.6 TERMINATION. Notwithstanding the exercise periods set forth in the Stock Option Agreement, exercise of an Award shall always be subject to the following: (a) If the Participant is Terminated for any reason except death or Disability, then Participant may exercise such Participant's Awards only to the extent that such Awards would have been exercisable upon the Termination Date and for the period of time after the Termination Date that is specified by the Committee, not to exceed five years. In the event that the Committee fails to specify such a time period, such Awards may be exercised no later than thirty (30) days after the Termination Date. However, in no event may such Awards be exercised after the expiration date of the Awards. (b) If the Participant is terminated because of death or Disability (or the Participant dies within the period of time that is specified by the Committee for the exercise of Participant's Awards following such termination or within Thirty (30) days of such termination if the Committee failed to otherwise specify the time period, as described in Section 5.6(a), above), then Participant's Awards may be exercised only to the extent that such Awards would have been exercisable by Participant on the Termination Date and must be exercised by Participant (or Participant's legal representative or authorized assignee) no later than twelve (12) months after the Termination Date in the case of disability or death (or such longer time period not exceeding five years as may be determined by the Committee), but in any event no later than the expiration date of the Awards. -3- 5.7 LIMITATION ON EXERCISE. The Committee may specify a reasonable minimum number of Shares that may be purchased on any exercise of an Award; PROVIDED that such minimum number will not prevent Participant from exercising the Award for the full number of Shares for which it is then exercisable. 5.8 LIMITATIONS ON ISOS. The aggregate Fair Market Value (determined as of the date of grant) of Shares with respect to which ISOs are exercisable for the first time by a Participant during any calendar year (under the Plan or under any other incentive stock option plan of the Company or any Affiliate, Parent or Subsidiary of the Company) shall not exceed $100,000. If the Fair Market Value of Shares on the date of grant with respect to which ISOs are exercisable for the first time by a Participant during any calendar year exceeds $100,000, the Awards for the first $100,000 worth of Shares to become exercisable in such calendar year shall be ISOs and the Awards for the amount in excess of $100,000 that become exercisable in that calendar year shall be NQSOs. In the event that the Code or the regulations promulgated thereunder are amended after the Effective Date of the Plan to provide for a different limit on the Fair Market Value of Shares permitted to be subject to ISOs, such different limit shall be automatically incorporated herein and shall apply to any Awards granted after the effective date of such amendment. 5.9 MODIFICATION, EXTENSION OR RENEWAL. The Committee may modify, extend or renew outstanding Awards and authorize the grant of new Awards in substitution therefor; PROVIDED that any such action may not, without the written consent of Participant, impair any of Participant's rights under any Award previously granted. Any outstanding ISO that is modified, extended, renewed or otherwise altered shall be treated in accordance with Section 424(h) of the Code. The Committee may reduce the Exercise Price of outstanding Awards without the consent of Participants affected by a written notice to them; PROVIDED, HOWEVER, that the Exercise Price may not be reduced below the minimum Exercise Price that would be permitted under Section 5.4 of the Plan for Awards granted on the date the action is taken to reduce the Exercise Price. 5.10 NO DISQUALIFICATION. Notwithstanding any other provision in the Plan, no term of the Plan relating to ISOs shall be interpreted, amended or altered, nor shall any discretion or authority granted under the Plan be exercised, so as to disqualify the Plan under Section 422 of the Code or, without the consent of the Participant affected, to disqualify any ISO under Section 422 of the Code. 6. PAYMENT FOR SHARE PURCHASES. Payment for Shares purchased pursuant to the Plan may be made in cash (by check) or, where expressly approved for the Participant by the Committee and where permitted by law: (a) by cancellation if indebtedness of the Company to the Participant; (b) by surrender of Shares that either: (1) have been owned by Participant for more than six (6) months and have been paid for within the meaning of SEC Rule 144 (and, if such shares were purchased from the Company by use of a promissory note, such note has been fully paid with respect to such Shares); or (2) were obtained by Participant in the public market; (c) by tender of a full recourse promissory note having such terms as may be approved by the Committee and bearing interest at a rate sufficient to avoid imputation of income under Section 483 and 1274 of the Code; PROVIDED, HOWEVER, that Participants who are not employees of the Company shall not be entitled to purchase Shares with a promissory note unless the note is adequately secured by collateral other than the Shares; PROVIDED, FURTHER, that the portion of the Purchase Price equal to the par value of the Shares, if any, must be paid in cash. (d) by waiver of compensation due or accrued to Participant for services rendered; (e) by tender of property; (f) provided that a public market for the Company's stock exists: -4- (1) through a "same day sale" commitment from Participant and a broker-dealer that is a member of the National Association of Securities Dealers (a "NASD DEALER") whereby the Participant irrevocably elects to exercise the Award and to sell a portion of the Shares so purchased in order to pay for the Exercise Price, and whereby the NASD Dealer irrevocably commits upon receipt of such Shares to forward the Exercise Price directly to the Company; or (2) through a "margin" commitment from Participant and a NASD Dealer whereby Participant irrevocably elects to exercise the Award and to pledge the Shares so purchased to the NASD Dealer in a margin account as security for a loan from the NASD Dealer in the amount of the Exercise Price, and whereby the NASD Dealer irrevocably commits upon receipt of such Shares to forward the exercise price directly to the Company; or (g) by any combination of the foregoing. 7. WITHHOLDING TAXES. 7.1 WITHHOLDING GENERALLY. Whenever Shares are to be issued in satisfaction of Awards granted under the Plan, the Company may require the Participant to remit to the Company an amount sufficient to satisfy federal, state and local withholding tax requirements prior to the delivery of any certificate or certificates for such Shares. Whenever, under the Plan, payments in satisfaction of Awards are to be made in cash, such payment shall be net of an amount sufficient to satisfy federal, state, and local withholding tax requirements. 7.2 STOCK WITHHOLDING. When, under applicable tax laws, a Participant incurs tax liability in connection with the exercise of any Award that is subject to tax withholding and the Participant is obligated to pay the Company the amount required to be withheld, the Committee may allow the Participant to satisfy the minimum withholding tax obligation by electing to have the Company withhold from the Shares to be issued that number of Shares having a Fair Market Value equal to the minimum amount required to be withheld, determined on the date that the amount of tax to be withheld is to be determined (the "TAX DATE"). All elections by a Participant to have Shares withheld for this purpose shall be made in writing in a form acceptable to the Committee and shall be subject to the following restrictions: (a) the election must be made on or prior to the applicable Tax Date; (b) once made, then except as provided below, the election shall be irrevocable as to the particular Shares as to which the election is made; (c) all elections shall be subject to the consent or disapproval of the Committee; (d) if the Participant is an Insider and if the Company is subject to Section 16(b) of the Exchange Act: (1) the election may not be made within six (6) months of the date of grant of the Award, except as otherwise permitted by SEC Rule 16b-3(e) under the Exchange Act, and (2) either (A) the election to use stock withholding must be irrevocably made at least six (6) months prior to the Tax Date (although such election may be revoked at any time at least six (6) months prior to the Tax Date) or (B) the exercise of the Award or election to use stock withholding must be made in the ten (10) day period beginning on the third day following the release of the Company's quarterly or annual summary statement of sales or earnings; and (e) in the event that the Tax Date is deferred until six (6) months after the delivery of Shares under Section 83(b) of the Code, the Participant shall receive the full number of Shares -5- with respect to which the exercise occurs, but such Participant shall be unconditionally obligated to tender back to the Company the proper number of Shares on the Tax Date. 8. PRIVILEGES OF STOCK OWNERSHIP. 8.1 VOTING AND DIVIDENDS. No Participant shall have any of the rights of a shareholder with respect to any Shares until the Shares are issued to the Participant. After Shares are issued to the Participant, the Participant shall be a shareholder and have all the rights of a shareholder with respect to such Shares, including the right to vote and receive all dividends or other distributions made or paid with respect to such Shares. 8.2 FINANCIAL STATEMENTS. The Company shall provide financial statements to each Participant annually during the period such Participant has Awards outstanding; PROVIDED, HOWEVER, the Company shall not be required to provide such financial statements to Participants whose services in connection with the Company assure them access to equivalent information. 9. TRANSFERABILITY. Subject to Section 4.1(j), Awards granted under the Plan, and any interest therein, shall not: (a) be transferable or assignable by the Participant, (b) be made subject to execution, attachment or similar process, otherwise than by will or by the laws of descent and distribution or as consistent with the specific Plan and Stock Option Agreement provisions relating thereto or (c) during the lifetime of the Participant, be exercisable by anyone other than the Participant, and any elections with respect to an Award, may be made only by the Participant. 10. CERTIFICATES. All certificates for Shares or other securities delivered under the Plan shall be subject to such stock transfer orders, legends and other restrictions as the Committee may deem necessary or advisable, including restrictions under any applicable federal, state or foreign securities law, or any rules, regulations and other requirements of the SEC or any stock exchange or automated quotation system upon which the Shares may be listed. 11. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. An Award shall not be effective unless such Award is in compliance with all applicable federal and state securities laws, rules and regulations of any governmental body, and the requirements of any stock exchange or automated quotation system upon which the Shares may then be listed, as they are in effect on the date of grant of the Award and also on the date of exercise or other issuance. Notwithstanding any other provision in the Plan, the Company shall have no obligation to issue or deliver certificates for Shares under the Plan prior to (a) obtaining any approvals from governmental agencies that the Company determines are necessary or advisable, and/or (b) completion of any registration or other qualification of such shares under any state or federal law or ruling of any governmental body that the Company determines to be necessary or advisable. The Company shall be under no obligation to register the Shares with the SEC or to effect compliance with the registration, qualification or listing requirements of any state securities laws, stock exchange or automated quotation system, and the Company shall have no liability for any inability or failure to do so. 12. NO OBLIGATION TO EMPLOY. Nothing in the Plan or any Award granted under the Plan shall confer or be deemed to confer on any Participant any right to continue in the employ of, or to continue any other relationship with, the Company or any Parent, Subsidiary or Affiliate of the Company or limit in any way the right of the Company or any Parent, Subsidiary or Affiliate of the Company to terminate Participant's employment or other relationship at any time, with or without cause. 13. EXCHANGE AND BUYOUT OF AWARDS. The Committee may, at any time or from time to time, authorize the Company, with the consent of the respective Participants, to issue new Awards in exchange for the surrender and cancellation of any or all outstanding Awards. The Committee may at any time buy from a Participant an Award previously granted with payment in cash, Shares or other consideration, based on such terms and conditions as the Committee and the Participant shall agree. -6- 14. CORPORATE TRANSACTIONS. 14.1 ASSUMPTION OR REPLACEMENT OF AWARDS BY SUCCESSOR. In the event of (a) a merger or consolidation in which the Company is not the surviving corporation (other than a merger or consolidation with a wholly-owned subsidiary, a reincorporation of the Company in a different jurisdiction, or other transaction in which there is no substantial change in the shareholders of the Company and the Awards granted under the Plan are assumed or replaced by the successor corporation, which assumption shall be binding on all Participants), (b) a dissolution or liquidation of the Company, (c) the sale of substantially all of the assets of the Company, or (d) any other transaction which qualifies as a "corporate transaction" under Section 424(a) of the Code wherein the shareholders of the Company give up all of their equity interest in the Company (EXCEPT for the acquisition, sale or transfer of all or substantially all of the outstanding shares of the Company), any or all outstanding Awards may be assumed or replaced by the successor corporation (if any), which assumption or replacement shall be binding on all Participants. In the alternative, the successor corporation may substitute equivalent Awards or provide substantially similar consideration to Participants as was provided to shareholders (after taking into account the existing provisions of the Awards). The successor corporation may also issue, in place of outstanding Shares of the Company held by the Participant, substantially similar shares or other property subject to repurchase restrictions no less favorable to the Participant. In the event such successor corporation (if any) refuses to assume or substitute Options, as provided above, pursuant to a transaction described in this Subsection 14.1, such Options shall accelerate and become exercisable in full at least ten days prior to and shall expire on the consummation of such event at such times and on such conditions as the Board shall determine. 14.2 OTHER TREATMENT OF AWARDS. Subject to any greater rights granted to Participants under the foregoing provisions of this Section 14, in the event of the occurrence of any transaction described in Section 14.1, any outstanding Awards shall be treated as provided in the applicable agreement or plan of merger, consolidation, dissolution, liquidation, sale of assets or other "corporate transaction." 14.3 ASSUMPTION OF AWARDS BY THE COMPANY. The Company, from time to time, also may substitute or assume outstanding awards granted by another company, whether in connection with an acquisition of such other company or otherwise, by either (a) granting an Award under the Plan in substitution of such other company's award, or (b) assuming such award as if it had been granted under the Plan if the terms of such assumed award could be applied to an Award granted under the Plan. Such substitution or assumption shall be permissible if the holder of the substituted or assumed award would have been eligible to be granted an Award under the Plan if the other company had applied the rules of the Plan to such grant. In the event the Company assumes an award granted by another company, the terms and conditions of such award shall remain unchanged (EXCEPT that the exercise price and the number and nature of Shares issuable upon exercise of any such option will be adjusted appropriately pursuant to Section 424(a) of the Code). In the event the Company elects to grant a new Option rather than assuming an existing option, such new Option may be granted with a similarly adjusted Exercise Price. 15. ADOPTION AND SHAREHOLDER APPROVAL. The Plan shall become effective on the date that it is adopted by the Board (the "EFFECTIVE DATE"). The Plan shall be approved by the shareholders of the Company (excluding Shares issued pursuant to this Plan), consistent with applicable laws, within twelve months before or after the Effective Date. Upon the Effective Date, the Board may grant Awards pursuant to the Plan; PROVIDED, HOWEVER, that: (a) no Award may be exercised prior to initial shareholder approval of the Plan; and (b) no Award granted pursuant to an increase in the number of Shares approved by the Board shall be exercised prior to the time such increase has been approved by the shareholders of the Company. For so long as and whenever the Company is subject to Section 16(b) of the Exchange Act, the Company will comply with the requirements of Rule 16b-3 (or its successor), as amended, with respect to shareholder approval. 16. TERM OF PLAN. The Plan will terminate ten (10) years from the Effective Date or, if earlier, the date of shareholder approval. -7- 17. AMENDMENT OR TERMINATION OF PLAN. The Board may at any time terminate or amend the Plan in any respect, including without limitation amendment of any form of Stock Option Agreement or instrument to be executed pursuant to the Plan; PROVIDED, HOWEVER, that the Board shall not, without the approval of the shareholders of the Company, amend the Plan in any manner that requires such shareholder approval pursuant to the Code or the regulations promulgated thereunder as such provisions apply to ISO plans or pursuant to the Exchange Act or Rule 16b-3 (or its successor), as amended, thereunder; PROVIDED, FURTHER, that no amendment may be made to outstanding Awards without the consent of the Participant. 18. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of the Plan by the Board, the submission of the Plan to the shareholders of the Company for approval, nor any provision of the Plan shall be construed as creating any limitations on the power of the Board to adopt such additional compensation arrangements as it may deem desirable, including, without limitation, the granting of stock options otherwise than under the Plan, and such arrangements may be either generally applicable or applicable only in specific cases. 19.
