Target Bonus

Your annual target bonus will be set at thirty percent (30%) of your annual Base Salary. Your bonus will be based seventy-five percent (75%) on your contribution to PDL’s achievement of its goals and objectives and twenty-five percent (25%) on your individual performance as determined by the CFO and the Compensation Committee of the Board. For additional details regarding the 2013 Bonus Plan, please see Attachment A. We will work together to develop your personal goals for 2013.

Long-Term Incentive

Effective ten (10) days following your hire date, PDL will grant you a long term incentive award (the “Long-Term Incentive’) comprised of two components: (i) the right to receive $70,400 in cash; and (ii) a number of unvested restricted shares of PDL common stock with a Grant Value equal to $30,200. For this purpose, “Grant Value’ means the closing price of PDL's common stock on the tenth (10^th) day following your hire date or, if the tenth (10^th) day following your hire date is not a trading day, then the closing price of the next trading day.

Subject to your continued employment through December 12, 2014 (“Vesting Period’), the Long-Term Incentive will vest and become payable upon December 12, 2014 (“Vesting Date’). The cash component may be increased based on company performance. If any of the performance goals set forth in the 2014 Long-Term Incentive Plan, attached as Attachment B, are achieved on or before December 12, 2014, then you may receive an additional cash payment equal to a percentage of your target cash payment (“Adjustment’). The amount of the Adjustment and the achievement of each performance goal will be determined by PDL’s Compensation Committee in its sole discretion, provided that the aggregate maximum cash payment may not exceed three times (3x) your target cash payment.

Dividend payments and other distributions made on the restricted share component of the Long-Term Incentive during the Vesting Period will accrue through the Vesting Period and will be paid, plus interest (based on the prevailing interest rate of the Merrill Lynch FFI Select Institutional Fund), to you on the Vesting Date.

In the event of a Change in Control, (i) the vesting of the restricted stock award, (ii) the payment of any accrued but unpaid dividends or other distributions, plus interest (at the rate set forth above), and (iii) the payment of the target cash payment, plus any Adjustments that the Compensation Committee determines has been earned as of the Change in Control, will accelerate and pay in connection with the Change in Control.

The Compensation Committee has indicated that it intends to adopt annually long term incentive plans similar to the above 2013-14 Long Term Incentive Plan. The Compensation Committee reserves the right to modify any or all of the terms of future long term incentive plans, including the cessation of such future long term incentive plans.

For additional details regarding the Long-Term Incentive program, please see Attachment B.

Termination without Cause or Resignation for Good Reason

If you are terminated without Cause or resign for Good Reason, (a) you will receive a lump sum cash payment equal to (i) one hundred percent (100%) of the sum of your Base Salary in effect immediately prior to the time of separation, (ii) seventy-five percent (75%) of the sum of your annual target bonus for the year in which separation occurs and (iii) twelve months of COBRA Benefits and (b)(i) any unvested cash payments and equity awards under any long-term incentive plan in effect at the date of separation shall ratably accelerate, vest and pay in proportion to the time lapsed during the vesting period, as increased by any adjustments and milestones earned by the time of payment and (ii) any accrued and unpaid dividends and interest on the then unvested equity awards shall vest and pay; provided that such payment and other benefit shall be contingent upon your signing a release of all claims against PDL in a form acceptable to the Company.

For additional details regarding your severance benefits and the meanings of “Cause’ and “Good Reason,’ please see Attachment C.

Housing and Relocation Assistance

Because PDL is domiciled in Nevada and because of your need to relocate, PDL will provide assistance to you to rent or purchase housing in Nevada proximate to PDL’s offices. PDL will pay up to $1,500 per month for five years in housing assistance. In addition, to defray your moving expenses, PDL will reimburse you for such expenses up to $10,000.

Health and Related Benefits

Through TriNet, PDL provides a welfare benefits package, including a comprehensive medical policy and dental plan, as well as life insurance coverage, in which you will be eligible to participate in accordance with PDL guidelines. In general, PDL pays 100% of premiums for employee medical, employee dental and employee vision coverage. In addition,

PDL funds between 90% and 95% of premiums for medical, dental and vision coverage for spouse, dependent, and domestic partner coverage. Exact reimbursement varies by plan selected.

For a summary of these benefits and your options, please see Attachment D.

Holidays, Vacation and Sick Leave

In 2013, full-time employees will be paid as if they worked ten (10) designated holidays. PDL also offers one (1) Unrestricted Floating Holiday during the calendar year to regular full-time employees. An Unrestricted Floating Holiday may be used at any time for any occasion, provided that the employee obtains advance management approval for the scheduled usage of the Unrestricted Floating Holiday.

In addition, each full-time employee accrues vacation time based on the number of regular hours worked. In any calendar year, you can accrue up to one hundred and sixty hours (160) hours or twenty (20) days of paid vacation time. Usage and scheduling of time off is subject to the direction and approval of your supervisor.

Finally, PDL offers sick leave when your own illness prevents you from reporting to work. Your sick leave is calculated in increments for each pay period and, like vacation time, is based upon hours worked. You can accrue up to forty-eight (48) hours or six (6) days of sick leave annually. For additional details regarding these policies, please see Attachment D.

401(k) Plan

Through Fidelity, PDL provides the opportunity for its employees to participate in our 401(k) Plan. Under the terms of PDL’s 401(k) Plan, the company matches 100% of the employee’s contribution up to 3% of their salary and matches 50% of the employee’s contribution from 3% to 5% of their salary. Vesting under the 401(k) Plan is immediate. The Compensation Committee reserves the right to modify any or all of the terms of PDL’s 401(k) Plan, including cessation of the 401(k) Plan.
