Exhibit 10.2

EXECUTION VERSION

EMPLOYMENT AND SEVERANCE AGREEMENT

THIS EMPLOYMENT AND SEVERANCE AGREEMENT (this “Agreement”) is entered into between Overland Storage, Inc., a California corporation (“Employer” or the “Company”) and Kurt L. Kalbfleisch (“Executive”) on September 29, 2009 (the “Effective Date”). This Agreement has been negotiated by and between the parties and is effective on the Effective Date.

The parties agree as follows:

1. Positions And Duties. Executive will be employed by the Company initially in the position of Vice President and Chief Financial Officer (“CFO”), reporting to the Chief Executive Officer (“CEO”), and shall do and perform all services, acts or things necessary or advisable to support the business of the Company. Executive shall also perform such duties that are normally associated with the position of CFO consistent with the bylaws of the Company and such other duties as may be requested by the CEO. Termination of Executive as an officer of the Company for any reason shall also constitute the resignation by Executive, effective upon such termination, of any and all officers or positions with the Company or any affiliate of the Company. Upon request, Executive shall provide the Company with additional written evidence of any such resignation.

1.1. Best Efforts/Full-Time. During the Employment Term (as defined in Section 1.2 herein), Executive will act in the best interests of Employer and devote his full business time and best efforts to the performance of his duties under this Agreement. Executive agrees to be available to render such services at all reasonable times and places and in accordance with Employer’s directives. Executive shall be assigned to work in the Company’s corporate offices in San Diego, California, but may be required to travel in connection with his duties. Executive will abide by all policies, procedures, and decisions made by Employer, as well as all federal, state and local laws, regulations or ordinances applicable to his employment. During his employment, Executive must not engage in any work, paid or unpaid, that creates an actual or potential conflict of interest with Employer’s business interests and if, in the opinion of the CEO or the Company’s Board of Directors (the “Board”), an actual or potential conflict exists, the CEO or Board may in its sole discretion require Executive to choose either to (i) discontinue the other work or (ii) resign without Good Reason from his employment with Employer. The foregoing restriction shall not preclude Executive from engaging in civic, charitable or religious activities, or from serving on boards of directors of companies or organizations so long such services do not pose a material conflict or materially interfere with his responsibilities to Employer. It is anticipated that Executive will generally devote no less than 40 hours per week to his duties for Employer unless he is on vacation or a leave of absence in accordance with the terms of this Agreement or the Company’s policies as in effect from time to time.

1.2. Term Of Employment. This Agreement shall commence on the Effective Date, and, unless terminated by either party in accordance with Section 5 herein, shall continue until the third anniversary of the Effective Date. Thereafter, unless Executive’s employment is terminated in accordance with Section 4 or unless one party provides the

other party with written notice of non-renewal of the Agreement at least 30 days prior to the applicable end date, this Agreement shall automatically renew for an additional one year term on such date and on each anniversary thereof (the period of employment hereunder shall be referred to herein as the “Employment Term”). This Agreement shall continue during the Employment Term to govern the terms and conditions of Executive’s employment, unless modified by the parties hereto in writing.

1.3. Termination. Executive reaffirms that Executive’s employment relationship with the Company is at-will and is terminable at any time and for any reason by either the Company or Executive, subject to the provisions hereof.

2. Compensation.

2.1. Base Salary. As of the Effective Date and as compensation for the proper and satisfactory performance of all duties under this Agreement, Executive shall earn a gross annual base salary of $225,000 ($9,375 gross per bi-weekly payroll period), less applicable state and federal taxes and other authorized payroll deductions, payable in accordance with Employer’s normal payroll practices but in no event less frequently than once per month (the “Base Salary”). Notwithstanding the foregoing, the Base Salary will be reduced by 10% immediately upon the Effective Date and will remain at such reduced level until such time as the 10% salary reduction is lifted for the other Vice Presidents of the Company who are executive officers and subject to such reduction. For purposes of calculation of the severance pursuant to Section 4, the original Base Salary is deemed to be $225,000.

2.2. Bonus. Executive will be eligible to receive potential quarterly or annual cash bonuses solely as determined (if any) from time to time by the Board or duly authorized committee thereof (and in each case in the sole discretion of the Board or duly authorized committee thereof). Any such bonuses will be based on the Company’s fiscal quarters or fiscal year, and will be paid to Executive within 74 days following the end of such fiscal quarter or year. If Executive’s employment terminates before the end of a fiscal quarter or year under Section 4.2, Section 4.3 or Section 4.5, Executive shall be eligible to receive a prorated amount of any target bonus that may be established and in effect (“Target Bonus”) for the fiscal quarter or year in which Executive’s employment with the Company terminates. If Executive’s employment terminates before the end of a fiscal quarter or year under Section 4.4, Executive shall be eligible to receive a prorated amount of bonus actually earned in accordance with the terms and conditions of the Company’s bonus program for the fiscal quarter or year in which Executive’s employment with the Company terminates. If Executive’s employment terminates before the end of a fiscal quarter or year under Section 4.1, Executive shall not be eligible to receive a bonus for that fiscal quarter or year.

2.3. Equity Incentives. Executive will be eligible to receive stock options or other equity incentives as determined from time to time by the Board or duly authorized committee thereof, and in each case in its sole discretion and in accordance with terms and conditions determined by the Board or duly authorized committee thereof.

2.4. Unilateral Modification of Compensation. Subject to Executive’s right to resign for Good Reason under Section 4.3 of this Agreement, Employer reserves the right to modify Executive’s cash compensation, at any time, at its sole and absolute discretion.

3. Customary Fringe Benefits. Executive shall be eligible for customary and usual benefits generally available to executive level employees of Employer, subject to the terms and conditions set forth in the applicable benefit plan or policy, including reimbursement for all eligible out of pocket expenses currently covered under the Company’s executive reimbursement policy. Employer reserves the right to change or eliminate any of the fringe benefits provided to executive level employees on a prospective basis at any time, at Employer’s sole and absolute discretion; provided, however, that Executive may, in his discretion, retain, or obtain, his personal life, accident, medical, dental, vision and/or other insurance plans and benefits, the costs of which shall be reimbursed by the Company to Executive (not to exceed the total cost of comparable benefits offered by the Company to Executive and his dependents through the Company’s plans). Executive understands that all benefits provided in this section may be reduced by, or subject to, all applicable taxes. Executive shall be eligible for paid annual flexible time off and all paid Employer holidays, each in accordance with the Employer’s standard policies as apply to other executive employees of the Company. Executive will be reimbursed for all reasonable, out-of-pocket business expenses incurred in the performance of his duties on behalf of Employer subject to Executive’s compliance with the Company’s established expense reimbursement policy. Reimbursement for air travel shall be subject to the Employer’s generally applicable travel expense reimbursement policies.

4. Termination.

4.1. Termination For Cause By Employer. Employer may terminate Executive’s employment under this Agreement immediately at any time for “Cause,” which shall include, but is not limited to: (a) acts or omissions constituting reckless or willful misconduct on the part of Executive with respect to his obligations or otherwise relating to the business of Employer that causes material harm to the Company or its reputation; (b) Executive’s material breach of this Agreement, which breach Executive fails to cure within 30 days after receiving written notice from the Board that specifies the specific conduct giving rise to the alleged breach; (c) Executive’s conviction or entry of a plea of nolo contendere for fraud, theft or embezzlement, or any felony or crime of moral turpitude; or (d) Executive’s willful neglect of duties as determined in the sole and exclusive discretion of Employer, which Executive fails to cure within 30 days after receiving written notice from the Board that specifies the specific duties that Executive has failed to perform.

4.1.1. Entitlements Upon Termination For Cause. In the event that Executive’s employment is terminated for Cause in accordance with Section 4.1, Executive shall be entitled to receive: (a) the Base Salary then in effect through the date of termination; (b) the amount of any unpaid bonus to which Executive is then entitled pursuant to Section 2.2, if any; and (c) any expense reimbursements to which Executive is entitled by virtue of his prior employment with Employer (collectively, (a), (b) and (c) above are referred to herein as the “Standard

-3-

Entitlements”). The Standard Entitlements shall be paid to such Executive within 30 days following termination or earlier if required by law. In the event of such termination for Cause, Executive shall not be entitled to receive (i) the Severance Payment or Accelerated Vesting and Extended Exercise Period Severance Benefit (as each are defined in Section 4.2 below) or any portion thereof, or (ii) any further vesting of stock options, and all other obligations of Employer to Executive pursuant to this Agreement shall automatically terminate and be completely extinguished.

4.2. Termination Without Cause By Employer. Employer may terminate Executive’s employment without Cause at any time and for any (or no) reason. If Employer terminates Executive’s employment without Cause, Executive shall be entitled to receive the Standard Entitlements, which shall be paid to Executive within 30 days following termination or earlier if required by law. In addition to the above, so long as Executive timely complies with all of the conditions in Section 4.2.1 below, Executive will be entitled to an aggregate severance payment equal to the sum of (i) an amount equal to 100% of the greater of Executive’s then Base Salary or original Base Salary, plus (ii) a portion of the Target Bonus prorated based on the number of days Executive was employed during the period on which the Target Bonus is based, plus (iii) an amount equal to the premiums Executive would be required to pay to continue life, accident, medical, dental and vision insurance coverage under the Company’s insurance plans for Executive and his eligible dependents pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) for a period of twelve(12) months following the date of termination, plus (iv) the amount necessary for Executive to continue life, accident, medical and dental insurance benefits for Executive and his eligible dependents for insurance coverage that he personally maintained in amounts substantially similar to those which Executive was entitled to receive under Section 3 of this Agreement immediately prior to the date of termination for a period of twelve(12) months following the date of termination (collectively, the “Severance Payment”). Subject to Sections 5 and 10, the Severance Payment shall be paid to Executive (less applicable state and federal taxes or other payroll deductions) in standard payroll cycles until the end of the twelfth month following the date of termination, provided that such payments shall not commence before Executive has satisfied the Release requirements specified in Section 4.2.1 and provided, further, that the initial payment shall commence sixty days after the Executive’s Separation from Service occurs. As used herein, a “Separation from Service” occurs when Executive dies, retires, or otherwise has a termination of employment with the Company that constitutes a “separation from service” within the meaning of Treasury Regulation Section 1.409A-1(h)(1), without regard to the optional alternative definitions available thereunder. Upon Executive’s termination of employment by the Company without Cause, subject to Section 5 and also subject to Executive timely satisfying the conditions specified in Section 4.2.1, any unvested portion of Executive’s then outstanding stock options and other equity-based awards granted by the Company that would otherwise vest during the twelve (12) months following the date of such termination shall vest in full as of the date of such termination, and, in the case of such vested stock options (including those stock options whose vesting was accelerated pursuant to the preceding clause), may be exercised in whole or in part at any time

-4-

within one (1) year of the date of such termination without Cause, subject to earlier termination upon the expiration of the maximum term of the applicable options or in connection with a corporate transaction involving the Company to the extent provided in the Plan and/or the award agreements that evidence such options (collectively, the “Accelerated Vesting and Extended Exercise Period Severance Benefit”). In the event of such termination without Cause, all of Employer’s other obligations pursuant to this Agreement except as provided in this Section 4.2 shall terminate automatically and extinguish completely following the date of such termination without Cause.

4.2.1. Conditions to Receive Severance Payment and the Accelerated Vesting and Extended Exercise Period Severance Benefit. The Severance Payment and the Accelerated Vesting and Extended Exercise Period Severance Benefit will be paid provided that all of the following conditions are timely met: (i) Executive complies with all surviving provisions of this Agreement as specified in Section 12.8 below; and (ii) within not more than 55 days of his termination of employment, the Company has received from the Executive an executed and effective (meaning that any time period for the Executive to revoke a release of claims has lapsed without revocation) full general release substantially in the form attached hereto as Exhibit A, releasing all claims, known or unknown, that Executive may have against Employer and Employer’s affiliates arising out of or in any way related to Executive’s employment or termination of employment with Employer (the “Release”).

4.3. Voluntary Resignation by Executive for Good Reason. If Executive notifies Employer in writing within 60 days following the initial existence of one of the circumstances constituting “Good Reason” (as defined in Section 4.3.1), Employer will be given 30 days from the receipt of such notice in which Employer may remedy or cure such condition. For purposes of the foregoing, if Executive does not timely provide notice to Employer, then Executive is deemed to have waived this right. If Employer fails to remedy or cure the condition set forth in Executive’s notice within 30 days from the receipt of such notice, then provided Executive timely resigns his employment for Good Reason as provided in Section 4.3.1, Executive shall be entitled to receive the Standard Entitlements, which shall be paid to Executive within 30 days following termination or earlier if required by law. In addition, so long as Executive timely complies with all of the conditions set forth in Sections 4.2.1 and 4.3.1, Executive will be entitled to receive the Severance Payment and the Accelerated Vesting and Extended Exercise Period Severance Benefit with payments being provided at the times specified in Section 4.2. In the event of such resignation for Good Reason, all of Employer’s other obligations pursuant to this Agreement except as provided in this Section 4.3 shall terminate automatically and extinguish completely following the date of such resignation for Good Reason.

4.3.1. Executive will be deemed to have resigned for “Good Reason” if Executive voluntarily terminates employment with the Company within one year after the initial occurrence of one or more of the following: (a) Employer reduces Executive’s Base Salary by more than ten percent (10%), (b) Executive’s authority, title, responsibilities and/or duties are materially reduced so that his

-5-

duties are no longer consistent with the position of Vice President and Chief Financial Officer; (c) a material breach of this Agreement by the Company; or (d) Employer relocates Executive’s principal place of work to a location more than fifty (50) miles from Employer’s current office location as of the Effective Date without his prior written approval

4.4. Voluntary Resignation By Executive without Good Reason. In the event Executive’s resignation is without Good Reason, Executive shall be entitled to receive the Standard Entitlements (to be paid within 30 days following such resignation or earlier as required by law), but shall not be entitled to receive (i) the Severance Payment or the Accelerated Vesting and Extended Exercise Period Severance Benefit or any portion thereof, or (ii) any further vesting of stock options; and all other obligations of Employer to Executive pursuant to this Agreement shall automatically terminate and be completely extinguished.

4.5. Termination Due to Executive’s Death or Disability. Executive’s employment shall terminate immediately upon Executive’s death or Disability. Upon Executive’s death or Disability, the Company shall pay Executive (or his estate, as applicable) within 30 days after the date of termination (or earlier to the extent required by law) the Standard Entitlements and shall allow Executive (or his estate, as applicable) to exercise any vested but unexercised portion of Executive’s outstanding stock options as of the date of termination of Executive’s employment within twelve (12) months after the termination of Executive’s employment with the Company, subject to earlier termination upon the expiration of the maximum term of the applicable options or in connection with a corporate transaction involving the Company to the extent provided in the Plan and/or the award agreements that evidence such options. For purposes of this Agreement, “Disability” shall mean Executive’s inability because of illness or incapacity substantiated by appropriate medical authority selected by the Company, to render the essential functions of Executive’s job as contemplated by this Agreement over a period of 180 consecutive days after taking into account any reasonable accommodations that would not cause an undue burden on the Company.

5. Effect of Change Of Control. In the event Executive’s employment is terminated by him for Good Reason or by the Company without Cause during the two year period following a “Change of Control” (as defined in Section 5.1), then the Severance Payment shall instead be paid to Executive in a single lump sum 60 days after his termination of employment provided such accelerated timing of the Severance Payment does not violate Internal Revenue Code (“Code”) Section 409A and any unvested portion of Executive’s then outstanding stock options and other equity-based awards granted by the Company shall vest in full as of the date of such termination.

-6-

5.1. Change of Control Definition. A “Change of Control” is defined to have occurred if, and only if, during the Employment Term:

(a) any individual, partnership, firm, corporation, association, trust, unincorporated organization or other entity or person, or any syndicate or group deemed to be a person under Section 14(d)(2) of the Securities Exchange Act of 1934 (“Exchange Act”) is or becomes the “Beneficial Owner” (as defined in Rule 13d-3 of the General Rules and Regulations under the Exchange Act), directly or indirectly, of securities of the Company representing 30% or more of the combined voting power of the Company’s then outstanding securities entitled to vote in the election of directors of the Company;

(b) there occurs a reorganization, merger, consolidation or other corporate transaction involving the Company (“Transaction”), in each case, with respect to which the shareholders of the Company immediately prior to such Transaction do not, immediately after the Transaction, own more than fifty (50) percent of the combined voting power of the Company or other corporation resulting from such Transaction; or

(c) all or substantially all of the assets of the Company are sold, liquidated or distributed.

6. Confidentiality/Intellectual Property Agreement And Insider Trading Policy. Executive agrees that he has read, signed, and will abide by the terms and conditions of Employer’s Confidentiality/Intellectual Property Agreement and Employer’s Insider Trading Policy.

Executive recognizes that his employment with the Company will involve contact with information of substantial value to the Company which gives the Company an advantage over its competitors who do not know or use it, including but not limited to, techniques, designs, drawings, processes, inventions, developments, equipment, prototypes, sales and customer information, and business and financial information relating to the business, products, practices and techniques of the Company (hereinafter referred to as “Confidential and Proprietary Information”). Executive will at all times regard and preserve as confidential such Confidential and Proprietary Information obtained by Executive from whatever source and will not, either during his employment with the Company or thereafter, publish or disclose any part of such Confidential and Proprietary Information in any manner at any time, or use the same except on behalf of the Company, without the prior written consent of the Company.

7. Non-Competition. Except with the prior written consent of Employer, Executive will not, during the Employment Term, engage in competition with Employer, either directly or indirectly, in any manner or capacity, as adviser, principal, agent, partner, officer, director, employee, member of any association or otherwise, in any phase of the business of developing, manufacturing and marketing of products which are in the same field of use or which otherwise compete with the product or products actively under development by Employer. Except as permitted herein, Executive agrees not to acquire, assume or participate in, directly or indirectly, any position, investment or interest known by Executive to be adverse or antagonistic to Employer, its business or prospects, financial or otherwise. Ownership by Executive, as a passive investment, of less than one percent (1%) of the outstanding shares of capital stock of any corporation with one or more classes of its capital stock listed on a national securities exchange or publicly traded in the over-the-counter market shall not constitute a breach of this Section 7.

-7-

8. Non-Solicitation. During the Employment Term and for a period of one year thereafter, irrespective of the manner of termination of employment, Executive agrees not to, directly or indirectly, separately, or in association with others: (a) interfere with, impair, disrupt, or damage Employer’s relationship with any of its customers by soliciting, encouraging, or causing others to solicit or encourage any of them, for the purpose of diverting or taking away the business such customers have with Employer; or (b) interfere with, impair, disrupt, or damage Employer’s business by soliciting, encouraging, or causing others to solicit or encourage, any of Employer’s employees to discontinue their employment with Employer.

9. Agreement To Arbitrate. Executive and Employer agree to arbitrate any claim or dispute (“Dispute”) arising out of or in any way related to this Agreement, the employment relationship between Employer and Executive or the termination of Executive’s employment, except as provided in Section 9.1, to the fullest extent permitted by law. Except as provided in Section 9.1, this method of resolving Disputes shall be the sole and exclusive remedy of the parties. Accordingly, the parties understand that, except as provided herein, they are giving up their rights to have their disputes decided in a court of law and, if applicable, by a jury, and instead agree that their disputes shall be decided by an arbitrator.

9.1. Scope of the Agreement. A Dispute shall include all disputes or claims between Executive and Employer arising out of, concerning or relating to Executive’s employment by Employer, including, without limitation: claims for breach of contract, tort, discrimination, harassment, wrongful termination, demotion, discipline, failure to accommodate, compensation or benefits claims, constitutional claims and claims for violation of any local, state or federal law, or common law, to the fullest extent permitted by law. A Dispute shall not include any dispute or claim, whether brought by either Executive or Employer, for: (a) workers’ compensation or unemployment insurance benefits; or (b) the exclusions from arbitration specified in the California Arbitration Act, California Code of Civil Procedure section 1281.8. For the purpose of this Section 9, references to “Employer” include Employer and all related or affiliated entities and their employees, supervisors, officers, directors, owners, shareholders, agents, pension or benefit plans, pension or benefit plan sponsors, fiduciaries, administrators, and the successors and assigns of any of them, and this Section 9 shall apply to them to the extent that Executive’s claims arise out of or relate to their actions on behalf of Employer.

9.2. Consideration. The parties agree that their mutual promise to arbitrate any and all disputes between them, except as provided in Section 9.1, rather than litigate them before the courts or other bodies, provides adequate consideration for this Section 9.

9.3. Initiation of Arbitration. Either party may initiate an arbitration proceeding by providing the other party with written notice of any and all claims forming the basis of such proceeding in sufficient detail to inform the other party of the substance of such claims. In no event shall the request for arbitration be made after the date when institution of legal or equitable proceedings based on such claims would be barred by the applicable statute of limitations.

-8-

9.4. Arbitration Procedure. The arbitration will be conducted by JAMS pursuant to its Rules for the Resolution of Employment Disputes in San Diego, California by a single, neutral arbitrator. The parties are entitled to representation by an attorney or other representative of their choosing. The arbitrator shall have the power to enter any award that could be entered by a judge of the Superior Court of the State of California, as applicable to the cause of action, and only such power. The arbitrator shall issue a written and signed statement of the basis of the arbitrator’s decision, including findings of fact and conclusions of law. The parties agree to abide by and perform any award rendered by the arbitrator. Judgment on the award may be entered in any court having jurisdiction thereof.

9.5. Costs of Arbitration. If Executive initiates arbitration against the Employer, Executive must pay a filing fee equal to the current filing fee in the appropriate court had Executive’s claim been brought there, and the Employer shall bear the remaining costs of the filing fees and arbitration forum, including arbitrator fees, case management fees, and forum hearing fees (the “Arbitration Fees”). If the Employer initiates arbitration against Executive, the Employer shall bear the entire cost of the Arbitration Fees. (Such costs do not include costs of attorneys, discovery, expert witnesses, or other costs which Executive would have been required to bear had the matter been filed in a court.) The arbitrator may award attorneys’ fees and costs to the prevailing party, except that Executive shall have no obligation to pay any of the Arbitration Fees even if Employer is deemed the prevailing party. If there is any dispute as to whether the Employer or Executive is the prevailing party, the arbitrator will decide that issue. Any postponement or cancellation fee imposed by the arbitration service will be paid by the party requesting the postponement or cancellation, unless the arbitrator determines that such fee would cause undue hardship on the party. At the conclusion of the arbitration, each party agrees to promptly pay any arbitration award imposed against that party.

9.6. Governing Law. All Disputes between the parties shall be governed, determined and resolved by the internal laws of the State of California, including the California Arbitration Act, California Code of Civil Procedure 1280 et seq.

9.7. Discovery. The parties may obtain discovery in aid of the arbitration to the fullest extent permitted under law, including California Code of Civil Procedure Section 1283.05. All discovery disputes shall be resolved by the arbitrator.

10. Code Section 409A. Notwithstanding anything to the contrary, if, at the time of his separation of service from Employer, Executive is a “specified employee” as defined pursuant to Code Section 409A, and if the amounts that Executive is entitled to receive pursuant to this Agreement are not otherwise exempt from Code Section 409A, then to the extent necessary to comply with Code Section 409A, no payments for such non-exempt amounts may be made under this Agreement before the date which is six (6) months after Executive’s separation from service from Employer or, if earlier, Executive’s date of death. All such

-9-

amounts, which would have otherwise been required to be paid during such six (6) months after Executive’s separation from service shall instead be paid (without interest) to Executive in one lump sum payment on the first business day of the seventh month after Executive’s separation from service from Employer or, if earlier, Executive’s date of death. All such remaining payments shall be made pursuant to their original terms and conditions. This Agreement is intended to comply with the applicable requirements of Code Section 409A and shall be construed and interpreted in accordance therewith. Employer may at any time amend this Agreement, or any payments to be made hereunder, as necessary to be in compliance with Code Section 409A and avoid the imposition on Executive of any potential excise taxes relating to Code Section 409A. Any reimbursements pursuant to the foregoing provisions of this Agreement shall be paid as soon as reasonably practicable and in all events not later than the end of Executive’s taxable year following the taxable year in which the related expense was incurred. Executive’s rights to reimbursement hereunder are not subject to liquidation or exchange for another benefit and the amount of expenses eligible for reimbursement in one taxable year shall not affect the amount of expenses eligible for reimbursement in any other taxable year.

11. Limitation on Payments. In the event that it is determined that any payment or distribution of any type to or for Executive’s benefit made by the Company, by any of its affiliates, by any person who acquires ownership or effective control or ownership of a substantial portion of the Company’s assets (within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended, and the regulations thereunder (the “Code”)) or by any affiliate of such person, whether paid or payable or distributed or distributable pursuant to the terms of an employment agreement or otherwise, would be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties with respect to such excise tax (such excise tax, together with any such interest or penalties, are collectively referred to as the “Excise Tax”), then such payments or distributions or benefits shall be payable either:

(i) in full; or

(ii) in a reduced amount with such reduced amount equal to the maximum amount payable that would result in no portion of such reduced payments or distributions or benefits being subject to the Excise Tax.

Executive shall receive the greater, on an after-tax basis, of (i) or (ii) above.

Unless Executive and the Company agree otherwise in writing, any determination required under this section shall be made in writing by an independent accountant (which may be the Company’s audit firm) selected by the Company (the “Accountant”) whose determination shall be conclusive and binding. Executive and the Company shall furnish the Accountant such documentation and documents as the Accountant may reasonably request in order to make a determination. The Company shall bear all costs that the Accountant may reasonably incur in connection with performing any calculations contemplated by this section.

-10-

12. General Provisions.

12.1. Successors And Assigns. The rights and obligations of Employer under this Agreement shall inure to the benefit of and shall be binding upon the successors and assigns of Employer. Executive shall not be entitled to assign any of Executive’s rights or obligations under this Agreement.

12.2. Indemnification. The indemnification provisions for officers and directors under Employer’s Bylaws will (to the maximum extent permitted by law) be extended to Executive. During the period of Executive’s employment by the Company and for a period of six years thereafter, the Company shall keep in place a directors’ and officers’ liability insurance policy (or policies) providing comprehensive coverage to Executive to the extent that the Company provides such coverage for any other present or former senior executive or director of the Company.

12.3. Waiver. Except as provided in Section 2.4, this Agreement may not be modified or amended except by an instrument in writing, signed by Executive and by a duly authorized representative of Employer other than Executive. Either party’s failure to enforce any provision of this Agreement shall not in any way be construed as an amendment or waiver of any such provision, or prevent that party thereafter from enforcing each and every other provision of this Agreement.

12.4. Severability. If any provision of this Agreement is held by an arbitrator or a court of law to be illegal, invalid or unenforceable, then: (a) that provision shall be deemed amended to achieve as nearly as possible the same economic effect as the original provision; and (b) the legality, validity and enforceability of the remaining provisions of this Agreement shall not be affected or impaired thereby.

12.5. Interpretation; Construction. This Agreement has been drafted by Employer, but Executive has participated in the negotiation of its terms. Furthermore, Executive acknowledges that he has had an opportunity to review and revise the Agreement and have it reviewed by legal counsel, if desired. Therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this Agreement.

12.6. Governing Law. This Agreement will be governed by and construed in accordance with the laws of the State of California.

12.7. Notices.

12.9. Entire Agreement. This Agreement constitutes the entire agreement between the parties relating to the subject matter herein and supersedes all prior or simultaneous representations, discussions, negotiations, and agreements, whether written or oral.

12.10. Counterparts. This Agreement may be executed in one or more original, facsimile or .PDF counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

12.11. Recovery of Attorney’s Fees and Expenses. If any litigation shall occur between Executive and Employer which arises out of or as a result of this Agreement, or which seeks an interpretation of this Agreement, the prevailing party shall be entitled to recover reasonable attorneys’ fees and costs.

12.12. Tax Consequences. The Company makes no representations regarding the tax consequence of any provision of this Agreement. Executive is advised to consult with his own tax advisor with respect to the tax treatment of any payment contained in this Agreement.
