1 EXHIBIT 10.22 [ALLERGAN LETTERHEAD] September 25, 1997 Mr. William C. Shepherd 1206 E. Balboa Boulevard Balboa, CA 92661-1420 Dear Bill, This letter agreement and release of all claims will serve to set forth all agreements and understandings relative to your termination from Allergan. The reason for the termination of employment is Early Retirement by Mutual Agreement. 1. TERMINATION DATE Your last day as an active employee will be January 1, 1998, (your "Termination Date"). 2. FINAL PAY You will be paid through your Termination Date. In addition, you will be paid for any earned but unused vacation hours, up to the maximum accrual of 13 weeks (520 hours) of pay at your base salary. You will cease to accrue additional vacation benefits after your Termination Date. 3. RESIGNATION AS DIRECTOR You shall tender your resignation as a member of the Allergan, Inc. Board of Directors and as a Director and/or officer of any Allergan subsidiary on which you serve, effective on your Termination Date. 4. SEVERANCE PAY You will receive severance pay over the next thirty six (36) months following your Termination Date, payable semi-monthly. This payment is contingent on your signing this letter agreement. The total severance value, at the rate of $89,166.67 per month, is $3,210,000. This rate reflects three times your highest annual salary in the last 5 year period plus three times the average of your two highest bonuses in the last 5 year period. If you elect not to sign this letter agreement, your severance will be equal to 3 months' base salary or $267,500. The 36-month period or the 3-month period (depending on whether you sign this letter agreement) is referred to in this letter as the "Severance Pay Period." 5. CONSULTING SUPPORT TO ALLERGAN As part of the consideration for your severance pay, you agree to provide consulting support to Allergan as requested by Allergan's CEO, up to a maximum of 50 days per year, during the severance pay period. - -------------------------------------------------------------------------------- 1 9/25/97 Initialed By: /S/ W.
