Palm, Inc. Management Retention Agreement

Exhibit 10.37

Palm, Inc.

Management Retention Agreement

This Management Retention Agreement (the “Agreement”) is made and entered into by and between Jonathan Rubinstein (the “Employee”) and Palm, Inc. (the “Company”), effective on the Employee’s first day of employment with the Company (the “Effective Date”).

RECITALS

A. It is expected that the Company from time to time may consider a Change of Control (as defined below). The Board of Directors of the Company (the “Board”) recognizes that such consideration can be a distraction to the Employee and can cause the Employee to consider alternative employment opportunities. The Board 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 the Employee, notwithstanding the possibility, threat or occurrence of a Change of Control of the Company.

B. The Board believes that it is in the best interests of the Company and its stockholders to provide the Employee with an incentive to continue his employment and to motivate the Employee to maximize the value of the Company upon a Change of Control for the benefit of its stockholders.

C. The Board believes that it is imperative to provide the Employee with severance benefits upon Employee’s termination of employment following a Change of Control which provides the Employee with enhanced financial security and incentive and encouragement to remain with the Company notwithstanding the possibility of a Change of Control.

D. Certain capitalized terms used in this Agreement are defined in Section 5 below.

The parties hereto agree as follows:

1. Term of Agreement. This Agreement shall commence on the Employee’s first day of employment with the Company and shall terminate upon the date that all obligations of the parties hereto with respect to this Agreement have been satisfied.

2. At-Will Employment. The Company and the Employee acknowledge that the Employee’s employment will be at-will, as defined under applicable law, and may be terminated by either party at any time, with or without cause or notice. If the Employee’s employment terminates for any reason, including (without limitation) any termination prior to a Change of Control, the Employee shall not be entitled to any payments, benefits, damages, awards or compensation other than as provided by this Agreement, or as may otherwise be available in accordance with the Company’s established employee plans or pursuant to other written agreements with the Company, including the Employee’s Severance Agreement.

3. Change of Control Benefits.

(a) Equity Compensation. If a Change of Control occurs before the date that Employee’s employment with the Company is terminated, or within three (3) months following the date that the Employee’s employment with the Company is terminated by the Company without Cause or by Employee for a Voluntary Termination for Good Reason, then:

(i) One Hundred percent (100%) of the unvested portion of any stock option held by the Employee shall be automatically accelerated in full so as to become completely vested and shall have a post-termination of employment exercise period equal to the earlier of the original option term or twelve (12) months from Employee’s date of termination of employment.

(ii) One Hundred percent (100%) of the unvested portion of any restricted stock, restricted stock units, performance shares or other Company equity compensation held by the Employee shall be automatically accelerated in full so as to become completely vested and shall be immediately paid, less any applicable tax withholding.

(b) Involuntary Termination other than for Cause, Death or Disability or Voluntary Termination for Good Reason Following A Change of Control. If, within three (3) months prior to or twelve (12) months following a Change of Control, Employee’s employment with the Company (or any subsidiary thereof) is terminated (i) involuntarily by the Company (or any subsidiary thereof) other than for Cause, death or Disability or (ii) by the Employee pursuant to a Voluntary Termination for Good Reason, then, subject to Employee entering into a standard form of mutual release of claims with the Company, the Company shall provide Employee with the following benefits upon such termination:

(i) Severance Payment. A lump-sum cash payment in an amount equal to one hundred percent (100%) of the Employee’s Annual Compensation, which shall be paid to the Employee on the day following the six-month anniversary of such termination of employment.

(ii) Continued Employee Benefits. Company-paid health, dental, vision, long-term disability and life insurance coverage at the same level of coverage as was provided to such Employee immediately prior to the Change of Control and at the same ratio of Company premium payment to Employee premium payment as was in effect immediately prior to the Change of Control (the “Company-Paid Coverage”). If such coverage included the Employee’s dependents immediately prior to the Change of Control, such dependents shall also be covered at Company expense. Company-Paid Coverage shall continue until the earlier of (A) two years from the date of termination, or (B) the date upon which the Employee and his dependents become covered under another employer’s group health, dental, vision, long-term disability or life insurance plans that provide Employee and his dependents with comparable benefits and levels of coverage. For purposes of Title X of the Consolidated Budget Reconciliation Act of 1985 (“COBRA”), the date of the “qualifying event” for Employee and his dependents shall be the date upon which the Company-Paid Coverage commences, and each month of Company-Paid Coverage provided hereunder shall offset a month of continuation coverage otherwise due under COBRA.

2

(iii) Pro-Rated Bonus Payment. A lump-sum cash payment, which shall be paid to the Employee on the day following the six-month anniversary of such termination of employment, equal to one hundred percent (100%) of the higher of (A) Employee’s target bonus as in effect for the fiscal year in which the Change of Control occurs or (B) Employee’s target bonus as in effect for the fiscal year in which Employee’s termination occurs, pro-rated by multiplying such bonus amount in clause (A) or (B), as applicable, by a fraction, the numerator of which shall be the number of days prior to Employee’s termination during such fiscal year, and the denominator of which shall be three hundred and sixty-five.

(c) Voluntary Resignation; Termination For Cause. If the Employee’s employment terminates by reason of the Employee’s voluntary resignation (and is not a Voluntary Termination for Good Reason), or if the Employee is terminated for Cause, then the Employee shall not be entitled to receive severance or other benefits except for those (if any) as may then be established under the Company’s (or any subsidiary’s) then existing severance and benefits plans or pursuant to other written agreements with the Company (or any subsidiary thereof).

(d) Disability; Death. If the Employee’s employment with the Company (or any subsidiary thereof) terminates as a result of the Employee’s Disability, or if Employee’s employment is terminated due to the death of the Employee, then the Employee shall not be entitled to receive severance or other benefits except for those (if any) as may then be established under the Company’s (or any subsidiary’s) then existing severance and benefits plans or pursuant to other written agreements with the Company (or any subsidiary thereof).

(e) Termination Apart from Change of Control. In the event the Employee’s employment is terminated for any reason, either more than three (3) months prior to the occurrence of a Change of Control or after the twelve (12) month period following a Change of Control, then the Employee shall be entitled to receive severance and any other benefits only as may then be established under the Company’s (or any subsidiary’s) then existing severance and benefits plans or pursuant to other written agreements with the Company and the Employee’s Severance Agreement.

4. Golden Parachute Excise Tax.

(a) In the event that the benefits provided for in this Agreement or otherwise provided by the Company (or any subsidiary thereof) to the Employee (including, but not by way of limitation, any accelerated vesting on equity awards) (the “Total Payments”) would subject the Employee to an excise tax (the “Excise Tax”) imposed under Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), then the Company (or any subsidiary thereof that employs the Employee at such time) will pay the Employee (i) an amount sufficient to pay the excise tax, and (ii) an additional amount sufficient to pay the Excise Tax and federal, state and local income and employment taxes arising from the payments made by the Company (or any subsidiary thereof that employs the Employee at such time) pursuant to this sentence. Any amount required to be paid to the Employee pursuant to the preceding sentence shall be referred to as the “Gross-Up Payment.”

(b) The determination of the Employee’s Excise Tax liability and the amount, if any, required to be paid under this Section 4 will be made in writing by independent auditors at one of the four largest United States accounting firms mutually agreed to by the Employee and the Company

3

(the “Accountants”). For purposes of making the calculations required by this Section 4, the Employee shall be deemed to pay federal, state and local income taxes at the highest marginal rate in effect in the calendar year in which the Gross-Up Payment will be made, based on the Employee’s residence. 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 (or any subsidiary thereof that employs the Employee at such time) and the Employee shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section 4. The Company will pay all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 4.

(c) The Accountants shall determine the Gross-Up Payment as soon as practicable after (i) the Change of Control (but in no event later than 15 days after the Change of Control), and also after (ii) the Employee’s termination of employment (but in no event later than 15 days after the termination). In addition, the Accountants shall make a determination of any Gross-Up Payment prior to a Change of Control or the Employee’s termination of employment upon written request of the Employee and assuming the Employee has a reasonable basis for believing that he may be entitled to a Gross-Up Payment prior to the Change of Control or termination of employment. The Gross-Up Payment shall be paid to the Employee within five days after the Accountants’ determination. In the event that the initial Gross-Up Payment made to the Employee is finally determined to be too large or small, the following rules shall apply. If the initial Gross-Up Payment was too small, the Company (or any subsidiary thereof that employs the Employee at such time) shall promptly make an additional payment to the Employee equal to the shortfall (plus any interest, penalties or additional amounts payable by executive with respect to such excess). If the initial Gross-Up Payment is too large, then the Employee shall repay the amount of the excess to the Company (or any subsidiary that has made such payment to the Employee), plus interest on the amount of such repayment at 120% of the applicable federal rate provided in section 1274 of the Code, but only to the extent that such repayment by the Employee would result in a dollar-for-dollar reduction in the Executive’s taxable income and wages for purposes of federal, state and local income and employment taxes). The Executive and the Company (or any subsidiary thereof that employs the Employee at such time) shall each reasonably cooperate with the other in connection with any administrative or judicial proceedings concerning the existence or amount of the Excise Tax with respect to the Total Payments (and associated income taxes, penalties and interest).

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

(a) Annual Compensation. “Annual Compensation” shall mean an amount equal to the sum of (i) the Employee’s annual base salary, and (ii) 100% of the Employee’s Target Bonus, as in effect on the date of the Change of Control or Employee’s termination, in each case, whichever is higher.

Executive and the Company agree to work in good faith to consider amendments to this Agreement which are necessary or appropriate to avoid imposition of any additional tax or income recognition to Executive under Section 409A of the Internal Revenue Code and any proposed, temporary or final Treasury Regulations and Internal Revenue Service guidance thereunder.
