CELGENE/PHARMION PROPOSED MERGER U.S. PHARMION/CELGENE RETENTION PLAN AND SEVERANCE PROGRAM SUMMARIES January 2008 PRIOR TO CONSUMMATION OF THE MERGER (THE "CLOSING") --------------------------------------------------- I. THE RETENTION PLAN The following is a summary of certain benefits to be provided to eligible Pharmion employees under the Retention Plan (the "Plan") adopted by Pharmion Corporation ("Pharmion") with the consent of Celgene Corporation ("Celgene") in connection with the proposed acquisition of Pharmion by Celgene (the acquisition is referred to as the "Merger"). This summary is provided for your convenience only and is qualified by the exact language in the Plan, a copy of which can be accessed on the Stock & Equity C&C, or by contacting Pam Herriott or Pat Pheffer in Pharmion's Human Resources Department. U.S. INCENTIVE BONUS PROGRAM FOR 2007 PERFORMANCE ------------------------------------------------- (Applies to all eligible employees who have a start date on or before December 31, 2007) Subject to the approval of Pharmion's Board of Directors, Pharmion will award annual bonuses in respect of 2007 achievements toward 2007 individual and corporate goals to all Pharmion employees currently eligible for incentive bonuses under Pharmion's incentive bonus compensation program. The 2007 individual goals were established by each employee's manager and the 2007 corporate goals were established with and approved by Pharmion's Board of Directors. The incentive bonuses may be paid in amounts up to 200% of each individual's annual bonus target (a set percentage of the employee's base salary at December 31st of the prior year, determined by position level, under the incentive bonus compensation program), with the actual amounts to be determined by Pharmion's Board of Directors. In the case of employees who began employment in 2007, incentive bonuses will be pro-rated for the partial year of employment. Each eligible employee's incentive bonus is determined based on an evaluation of both individual performance and corporate performance in proportions previously established for each employee. An employee must be employed with Pharmion at the time the bonus is paid in order to be eligible to receive a 2007 incentive bonus. The 2007 incentive bonuses will be paid in March 2008. ADDITIONAL SALES INCENTIVE PROGRAM - FIRST AND SECOND QUARTERS 2008 ------------------------------------------------------------------- Subject to the achievement of applicable Pharmion quarterly sales targets, U.S. field-based sales employees will be paid their quarterly bonuses as outlined in the Pharmion Sales Incentive Compensation Plan. An additional Challenge Bonus for each of the 1st and 2nd quarters of 2008, predicated upon specific target goal achievement, as previously communicated by Pharmion's Sales 1 leadership, may be paid to U.S. field-based sales employees, subject to continued employment with Pharmion (or its successor) through the end of the calendar quarter to which such bonus corresponds. RETENTION "STAY" BONUS ---------------------- All eligible Pharmion employees (those full and part-time employees who were employed by or who accepted an offer of employment on or before the announcement of the Merger, November 18, 2007) who remain employed by Pharmion through the Closing will be entitled to receive a retention bonus payable as soon as practicable, but not later than thirty (30) days, following the Closing in an amount determined in accordance with the table below. In the event an otherwise eligible employee resigns or is terminated by Pharmion for any reason prior to the Closing, such employee will forfeit the right to receive any retention bonus. ------------------------------------------------------- ----------------------------------------------------- Applicable Measurement Date Amount of Retention Bonus ------------------------------------------------------- ----------------------------------------------------- If the Closing occurs on or before 25% of the eligible employee's annual base salary as of 12/01/07 June 1, 2008 ------------------------------------------------------- ----------------------------------------------------- If the Closing occurs after June 1, 2008 50% of the eligible employee's annual base salary as of 12/01/07 ------------------------------------------------------- ----------------------------------------------------- RESTRICTED STOCK UNIT VESTING Subject to your continued service with Pharmion through the Closing, immediately prior to the Closing, any unvested restricted stock unit awards (RSUs) will become fully vested, and if applicable, settle, in net shares subject to all applicable income and employment tax withholding. For a more detailed explanation of the treatment of outstanding RSUs, please refer to the document entitled "To Holders of Options to Purchase Shares of Common Stock and Restricted Stock Unit Awards under the Pharmion Corporation 2000 Stock Incentive Plan" sent to such Holders on January 4, 2008 via email from Steve Dupont, Pharmion's General Counsel. 2 FOLLOWING THE CLOSING --------------------- II. THE CELGENE/PHARMION EMPLOYEE SEVERANCE PROGRAM Celgene has agreed to provide severance benefits under a severance program for Pharmion employees who will not continue to be employed by Celgene or one of its subsidiaries, or whose employment with Celgene may be terminated, following the Closing, subject to the terms and conditions stated herein. Pharmion executive officers with an employment agreement with Pharmion are not eligible for payments or benefits under the Celgene severance program. In general, under the terms of the severance program, in the event of a termination of a former Pharmion employee's service by Celgene without "Cause" or by such employee as a result of Celgene's failure to provide such employee with "Comparable Employment" during the period commencing on the Closing and ending on the 12-month anniversary thereof, such employee will be entitled to the payments and benefits described in Items 1 through 4 below. For purposes of the severance program, the term "Cause" is defined in the Pharmion 2000 Stock Incentive Plan [located on the Pharmion Stock & Equity C&C, 2(d)]. For purposes of the severance plan, the term "Comparable Employment" is defined as a former Pharmion employee's position, or an offer of a position, with Celgene (or its successor) or its subsidiaries on and following the Closing (i) which does not result in a material reduction in scope, or material change in content, of such employee's duties and responsibilities with Pharmion, (ii) which provides such employee with compensation and employee benefits (other than equity compensation) that are comparable in the aggregate to the greater of those provided by Celgene to similarly situated employees of Celgene and those provided by Pharmion to such employee immediately prior to the Closing, and (iii) which does not require such employee to relocate such employee's principal business location beyond 50 miles from such employee's principal business location immediately prior to the Closing. The right to receive payments and benefits under the severance plan will be conditioned on the terminated employee executing a general release of claims in favor of Celgene and its affiliates. 1.

Health Plan Coverage -------------------- In addition, employees eligible for a severance award as described in Item 1 above will be eligible for continued health plan coverage through COBRA for themselves and their qualified beneficiaries at "active employee rates" for the period utilized to calculate the base salary severance award and based on the health plan coverage applicable to such employee and their qualified beneficiaries immediately prior to termination. "Active employee rates" means the same rates charged to active employees. At the end of the period utilized to calculate the base salary severance award, each former employee will be eligible to continue COBRA health plan coverage, at the former employee's election and upon such former employee's payment of the full premium under COBRA. 4 3. Employee Stock Options ---------------------- Employees whose employment with Pharmion is terminated following the Merger as described above may be entitled to full vesting of such employee's unvested Pharmion stock options (as converted at Closing to Celgene stock options) and such employees will have the period of time to exercise such options to purchase Celgene common stock as stated in their original stock option agreements. Please refer to the document entitled "To Holders of Options to Purchase Shares of Common Stock and Restricted Stock Unit Awards under the Pharmion Corporation 2000 Stock Incentive Plan" sent to such Holders on January 4, 2008 via email from Steve Dupont, Pharmion's General Counsel. 4.
