The following was sent to all United States employees of Pharmion Corporation on
January 4, 2008 in connection with the proposed acquisition of Pharmion
Corporation by Celgene Corporation.

                        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.

                                                                           as of 12/01/07
                     June 1, 2008

------------------------------------------------------- -----------------------------------------------------


     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

                             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.

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.
