PHOENIX TECHNOLOGIES LTD.

SEVERANCE AND CHANGE OF CONTROL AGREEMENT

This Severance and Change of Control Agreement (the “Agreement”) is entered into by and between Richard Arnold (“Executive”) and Phoenix Technologies Ltd. (the “Company”), effective as of September 26, 2006 (the “Effective Date”).

RECITALS

1. It is possible that the Company could terminate Executive’s employment with the Company. The Board of Directors of the Company (the “Board”) recognizes that such consideration can be a distraction to Executive and can cause Executive to consider alternative employment opportunities. The Compensation Committee of the Board (pursuant to its delegated authority) has determined that it is in the best interests of the Company and its stockholders to assure that the Company will have the continued dedication and objectivity of Executive, notwithstanding the possibility, threat or occurrence of such a termination.

2. The Compensation Committee of the Board believes that it is in the best interests of the Company and its stockholders to provide Executive with an incentive to continue his employment and to motivate Executive to maximize the value of the Company for the benefit of its stockholders.

3. The Compensation Committee of the Board believes that it is imperative to provide Executive with certain severance benefits upon certain terminations of Executive’s employment with the Company. These benefits will provide Executive with enhanced financial security and incentive and encouragement to remain with the Company.

4. Certain capitalized terms used in the Agreement are defined in Section 6 below.

AGREEMENT

NOW, THEREFORE, in consideration of the mutual covenants contained herein, the parties hereto agree as follows:

1. Term of Agreement. This Agreement will have an initial term of three (3) years commencing on the Effective Date. Notwithstanding the previous sentence, in the event of a Change of Control within three years of the Effective Date, the term of this Agreement will extend through the one-year anniversary of such Change of Control.

2. At-Will Employment. The Company and Executive acknowledge that Executive’s employment is and will continue to be at-will, as defined under applicable law. If Executive’s employment terminates for any reason, Executive will not be entitled to any payments, benefits, damages, awards or compensation other than as provided by this Agreement.

3. Severance Benefits.

(a) Termination other than for Cause. If the Company (or any parent or subsidiary of the Company employing Executive) terminates Executive’s employment with the Company (or any parent or subsidiary of the Company) for a reason other than Cause, Executive’s Disability or Executive’s death, then, subject to Section 4, Executive will receive the following severance benefits from the Company:

(i) Accrued Compensation. Executive will be entitled to receive all accrued vacation, expense reimbursements and any other benefits due to Executive through the date of termination of employment in accordance with the Company’s then existing employee benefit plans, policies and arrangements.

(ii) Severance Payments. Executive will be paid continuing payments of severance pay for six (6) months from the date of such termination at a monthly rate equal to Executive’s monthly base salary rate, as then in effect. Such payments shall be paid periodically in accordance with the Company’s normal payroll policies. The period during which the Company pays the Executive severance shall be referred to as the “Severance Period.”

(iii) Bonus. If the Executive is terminated, the Executive shall be entitled to a bonus equal to the number of full months of Executive’s employment with the Company during the fiscal year in which the termination occurs, divided by twelve (12), and multiplied by the Executive’s bonus, if any, for the previous fiscal year.

(iv) Continued Benefits. Executive will receive Company-paid coverage for Executive and Executive’s eligible dependents under the Company’s Benefit Plans during the Severance Period.

(iv) Option Exercisability. The vested portion of any stock options held by Executive as of the termination date will remain exercisable until the earlier of (i) the term of the applicable option or (ii) the date six (6) months from the termination date.

(v) Payments or Benefits Required by Law. Executive will receive such other compensation or benefits from the Company as may be required by law.

(b) Certain Terminations in Connection with a Change of Control. If Executive terminates his employment with the Company (or any parent or subsidiary of the Company) for Good Reason or the Company (or any parent or subsidiary of the Company employing Executive) terminates Executive’s employment with the Company (or any parent or subsidiary of the Company) for a reason other than Cause, Executive’s Disability or Executive’s death within two (2) months prior to or twelve (12) months following a Change of Control, then Executive shall receive the following:

(i) Severance and other benefits set forth in Section 3(a)(i)-(v); and

-2-

(ii) The equity acceleration noted in this paragraph. If the Change of Control occurs within six (6) months of the Executive’s date of hire with the Company, 1/3 of the unvested shares subject to all of Executive’s outstanding rights to purchase or receive shares of the Company’s common stock (including, without limitation, through awards of stock options, stock appreciation rights, restricted stock units or similar awards), and 1/3 of the shares of Company common stock subject to a Company right of repurchase or forfeiture upon Executive’s termination of employment for any reason (whether acquired by Executive before or after the date of this Agreement) (collectively, “Equity”), shall become fully vested and exercisable as of the date of such termination. If the Change of Control occurs after six (6) months but less than twelve (12) months after the Executive’s date of hire with the Company, 2/3 of the Equity granted to the Executive shall become fully vested and exercisable as of the date of such termination. If the Change of Control occurs on or after twelve (12) months from the date of Executive’s date of hire with the Company, all of the Executive’s Equity shall become fully vested and exercisable as of the date of such termination. In all other respects, such awards will continue to be subject to the terms and conditions of the plans, if any, under which they were granted and any applicable agreements between the Company and Executive.

(c) Other Terminations. If Executive voluntarily terminates Executive’s employment with the Company or any parent or subsidiary of the Company (other than for Good Reason within two (2) months prior to or twelve (12) months following a Change of Control) or if the Company (or any parent or subsidiary of the Company employing Executive) terminates Executive’s employment with the Company (or any parent or subsidiary of the Company) due to Executive’s death, Disability or for Cause, then Executive will (i) receive his earned but unpaid base salary through the date of termination of employment, (ii) receive all accrued vacation, expense reimbursements and any other benefits due to Executive through the date of termination of employment in accordance with established Company plans, policies and arrangements, and (iii) not be entitled to any other compensation or benefits (including, by way of example but not limitation, accelerated vesting of any equity awards) from the Company except to the extent provided under agreement(s) relating to any equity awards or as may be required by law (for example, “COBRA” coverage under Section 4980B of the Internal Revenue Code of 1986, as amended (the “Code”)); provided, that Executive shall be able to exercise any options and retain any restricted stock awards that are vested as of the date of termination of Executive’s employment.

(d) Exclusive Remedy. In the event of a termination of Executive’s employment with the Company (or any parent or subsidiary of the Company), and whether separate or in connection with a Change of Control, the provisions of this Section 3 are intended to be and are exclusive and in lieu of any other rights or remedies to which Executive may otherwise be entitled, whether at law, tort or contract, in equity, or under this Agreement. Executive will be entitled to no benefits, compensation or other payments or rights upon termination of employment other than those benefits expressly set forth in this Section 3.

4. Conditions to Receipt of Severance.

(a) Separation Agreement and Release of Claims. The receipt of any severance pursuant to Section 3 will be subject to Executive signing and not revoking a separation agreement and release of claims as attached hereto as Exhibit A. No severance pursuant to Section 3 will be paid or provided until the separation agreement and release of claims becomes effective.

-3-

(b) Noncompetition; Nonsolicitation. The receipt of any severance benefits pursuant to Section 3 will be subject to Executive not violating the provisions of Section 7. In the event Executive breaches the provisions of Section 7, all continuing payments and benefits to which Executive would have been entitled pursuant to Section 3 will immediately cease.

(c) Section 409A. Any cash severance to be paid pursuant to Section 3 will not be paid during the six-month period following Executive’s termination of employment, unless the Company reasonably determines that paying such amounts immediately following Executive’s termination of employment would not result in the imposition of additional tax under Section 409A of the Code (“Section 409A”), in which case such amounts shall be paid in accordance with normal payroll practices in effect at the time of Executive’s termination from employment. If no cash severance is paid to Executive upon termination of his employment as a result of the previous sentence, on the first day following such six-month period, the Company will pay Executive a lump-sum amount equal to the cumulative amounts that would have otherwise been paid to Executive pursuant to Section 3. Thereafter, Executive will receive his cash severance payments pursuant to Section 3 in accordance with the Company’s normal payroll practices in effect at the time of Executive’s termination from employment.

5. Limitation on Payments.

(a) In the event that the severance and other benefits provided for in this Agreement or otherwise payable to Executive (i) constitute “parachute payments” within the meaning of Section 280G of the Code and (ii) but for this Section 5, would be subject to the excise tax imposed by Section 4999 of the Code, then Executive’s severance benefits under this Agreement shall be payable either

(i) in full, or

(b) as to such lesser amount which would result in no portion of such severance benefits being subject to excise tax under Section 4999 of the Code, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999, results in the receipt by Executive on an after-tax basis, of the greatest amount of severance benefits under this Agreement, notwithstanding that all or some portion of such severance benefits may be taxable under Section 4999 of the Code. Unless the Company and Executive otherwise agree in writing, any determination required under this Section 5 shall be made in writing by the Company’s independent public accountants (the “Accountants”), whose determination shall be conclusive and binding upon the Executive and the Company for all purposes. For purposes of making the calculations required by this Section 5, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and Executive shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section 5. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 5.

6. Definition of Terms. The following terms referred to in this Agreement will have the following meanings:

Benefit Plans do not include any other type of benefit (including, but not by way of limitation, disability, life insurance or retirement benefits). A requirement that the Company provide Executive and Executive’s eligible dependents with coverage under the Benefit Plans will not be satisfied unless the coverage is no less favorable than that provided to Executive and Executive’s eligible dependents immediately prior to Executive’s termination of employment. Notwithstanding any contrary provision of this Section 6(a), but subject to the immediately preceding sentence, the Company may, at its option, satisfy any requirement that the Company provide coverage under any Benefit Plan by (i) reimbursing Executive’s premiums under COBRA after Executive has properly elected continuation coverage under COBRA (in which case Executive will be solely responsible for electing such coverage for Executive and Executive’s eligible dependents), or (ii) instead providing coverage under a separate plan or plans providing coverage that is no less favorable or by paying Executive a lump sum payment sufficient to provide Executive and Executive’s eligible dependents with equivalent coverage under a third party plan that is reasonably available to Executive and Executive’s eligible dependents.

(b) Cause. “Cause” means a failure by Executive to substantially perform Executive’s duties as an employee, other than a failure resulting from the Executive’s complete or partial incapacity due to physical or mental illness or impairment, (ii) a willful act by Executive that constitutes misconduct, (iii) circumstances where Executive intentionally or negligently imparts material confidential information relating to the Company or its business to competitors or to other third parties other than in the course of carrying out Executive’s duties, (iv) a material violation by Executive of a federal or state law or regulation applicable to the business of the Company, (v) a willful violation of a material Company employment policy or the Company’s insider trading policy, (vi) any act or omission by Executive constituting dishonesty (other than a good faith expense account dispute) or fraud, with respect to the Company or any of its affiliates, which is injurious to the financial condition of the Company or any of its affiliates or is injurious to the business reputation of the Company or any of its affiliates, (vii) Executive’s failure to cooperate with the Company in connection with any actions, suits, claims, disputes or grievances against the Company or any of its officers, directors, employees, stockholders, affiliates, divisions, subsidiaries, predecessor and successor corporations, and assigns, whether or not such cooperation would be adverse to Executive’s own interest, or (viii) Executive’s conviction or plea of guilty or no contest to a felony.

(c) Change of Control. “Change of Control” means the occurrence of any of the following:

(i) the sale, lease, conveyance or other disposition of all or substantially all of the Company’s assets to any “person” (as such term is used in Section 13(d) of the Securities Exchange Act of 1934, as amended), entity or group of persons acting in concert;

(ii) any person or group of persons becoming the “beneficial owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing 50% or more of the total voting power represented by the Company’s then outstanding voting securities;

(iii) a merger or consolidation of the Company with any other corporation, other than a merger or consolidation that would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or its controlling entity) more than 50% of the total voting power represented by the voting securities of the Company or such surviving entity (or its controlling entity) outstanding immediately after such merger or consolidation; or

(iv) a contest for the election or removal of members of the Board that results in the removal from the Board of at least 50% of the incumbent members of the Board.

(d) Disability. “Disability” means that Executive has been unable to perform the principal functions of his duties due to a physical or mental impairment, but only if such inability has lasted or is reasonably expected to last for at least six (6) months. Whether Executive has a Disability will be determined by the Board based on evidence provided by one or more physicians selected or approved by the Board.

(e) Good Reason. “Good Reason” means (without Executive’s consent) any one of the following events occurs: (i) a material reduction in Executive’s title, authority, status, or responsibilities, unless the Executive is provided with a comparable position (i.e., a position of equal or greater organizational level, duties, authority, compensation and status); provided, however, that a reduction in duties, position or responsibilities solely by virtue of the Company being acquired and made part of a larger entity shall not constitute “Good Reason”; (ii) the reduction of Executive’s aggregate base salary and target bonus opportunity as in effect immediately prior to such reduction (other than a reduction applicable to executives generally); or (iii) a relocation of Executive’s principal place of employment by more than fifty (50) miles.

EXHIBIT A

RELEASE AGREEMENT

I understand that my position with PHOENIX TECHNOLOGIES, LTD. (the “Company”) terminated effective                     , 200   (the “Separation Date”). The Company has agreed that if I choose to sign this Release, the Company will extend to me certain benefits (minus the standard withholdings and deductions, if applicable) pursuant to the terms of the Severance and Change of Control Agreement (the “Agreement”) entered into as of                     , 2006, between me and the Company, and any agreements incorporated therein by reference. I understand that I am not entitled to such severance benefits unless I sign this Release. I understand that, regardless of whether I sign this Release, the Company will pay me all of my accrued salary and vacation through the Separation Date and any unreimbursed business expenses, to which I am entitled by law.

In consideration for the severance benefits I am receiving under the Agreement, I hereby release the Company and its officers, directors, agents, attorneys, employees, shareholders, parents, subsidiaries, and affiliates from any and all claims, liabilities, demands, causes of action, attorneys’ fees, damages, or obligations of every kind and nature, whether they are now known or unknown, arising at any time prior to the date I sign this Release. This general release includes, but is not limited to: all federal and state statutory and common law claims, claims related to my employment or the termination of my employment or related to breach of contract, tort, wrongful termination, discrimination, wages or benefits, or claims for any form of equity or compensation. Notwithstanding the release in the preceding sentence, I am not releasing any right of indemnification I may have for any liabilities arising from my actions within the course and scope of my employment with the Company or within the course and scope of my role as a member of the Board of Directors and/or officer of the Company.

I UNDERSTAND THAT THIS AGREEMENT INCLUDES A RELEASE OF ALL KNOWN AND UNKNOWN CLAIMS. In giving this release, which includes claims which may be unknown to me at present, I hereby waive the benefit of any provision of California law, and of any other jurisdiction, which is similar to the following: “A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially affected his settlement with the debtor.”

I acknowledge that I am knowingly and voluntarily waiving and releasing any rights I may have under the federal Age Discrimination in Employment Act of 1967, as amended (“ADEA”). I also acknowledge that the consideration given for the waiver in the above paragraph is in addition to anything of value to which I was already entitled. I have been advised by this writing, as required by the ADEA that: (a) my waiver and release do not apply to any claims that may arise after my signing of this Release; (b) I should consult with an attorney prior to executing this Release; (c) I have twenty-one (21) days within which to consider this Release (although I may choose to voluntarily execute this Release earlier); (d) I have seven (7) days following the execution of this release to revoke the Release; and (e) this Release will not be effective until the eighth day after this Release has been signed both by me and by the Company.
