SEVERANCE AGREEMENT


         THIS AGREEMENT, made this 2nd day of February, 1998, by and between
Pharmaceutical Product Development, Inc. ("PPD") and Thomas D'Alonzo
("Employee").

         WHEREAS, Employee is a valued employee of PPD and in order to induce
Employee to remain in the employ of PPD, PPD desires to provide the severance
benefits hereinafter described in the event of a "Change in Control", as
hereinafter defined, of PPD.

         NOW, THEREFORE, it is agreed as follows:

         1.       Definitions

                  a. "Change in Control" means a change of control of a nature
that would be required to be reported in response to Item 6(e) of Schedule 14A
of Regulation 14A promulgated under the Securities Exchange Act of 1934, as
amended ("Exchange Act"), provided that such a Change in Control shall be deemed
to have occurred if any "person" (as such term is used in Sections 13(d) and
14(d)(2) of the Exchange Act) is or becomes the beneficial owner, directly or
indirectly, of securities of PPD representing 50% or more of the combined voting
power of PPD's then outstanding securities.

                  b. "Constructive Termination" means a termination of
Employee's employment by PPD during the Covered Period initiated by Employee
after (i) a substantial diminution or alteration in the duties of Employee, (ii)
a reduction by PPD in Employee's base salary in effect on the date of the Change
in Control, or (iii) the relocation of Employee's primary work location to a
location that is more than twenty-five (25) miles from Employee's primary work
location prior to the Change in Control. Constructive Termination specifically
does not include termination of Employee by reason of death, Disability or
retirement at or after age 65. Employee shall give PPD written notice of a
Constructive Termination, which notice shall provide a brief description of the
circumstances which Employee asserts gives rise to a right of Constructive
Termination, and PPD shall have ten (10) days from receipt of said notice within
which to remedy said circumstances.

                  c. "Covered Period" means the time period commencing on the
date of and coincident with a Change of Control and ending one year thereafter.

                  d. "Disability" means the inability of Employee to perform his
assigned duties for PPD for a period of three (3) months due to Employee's
physical or mental illness as determined by a reputable medical doctor.

                  e. "PPD" means Pharmaceutical Product Development, Inc. and
all of its subsidiaries and affiliated entities.

                  f. "Termination for Cause" means (i) an act or acts involving
fraud, embezzlement or theft from PPD, (ii) Employee's willful and repeated
failure to follow directions of the Board of Directors that continues for at
least ten (10) days following written notice of the Board of Directors of such
failure to follow directions, or (iii) termination for cause as defined in and
made pursuant to a then effective employment agreement, if any, between Employee
and PPD.

         2. Compensation Upon Change of Control. If during the Covered Period
(i) PPD terminates Employee's employment for reason other than Termination for
Cause or (ii) Employee's employment is terminated by reason of Constructive
Termination, Employee shall be entitled to the following compensation and
benefits:

                  a. PPD shall pay Employee a lump sum equal to Employee's W-2
compensation for the twelve (12) months ending on the last day of the month
preceding the month of Employee's termination, said sum to be paid within ten
(10) days after Employee's termination of employment.

                  b. PPD shall pay Employee any bonus or deferred compensation
(whether in the form of cash, stock or otherwise) accrued but unpaid as of
Employee's termination, said sum to be paid within ten (10) days after
Employee's termination of employment.

                  c. For a period of one year after Employee's termination of
employment with PPD, PPD shall continue to pay for and provide existing employee
welfare benefits which Employee is receiving as of the date of termination of
employment, including life insurance, health, medical, dental, vision and
wellness, accidental death and dismemberment and disability benefits; provided,
however, that PPD's obligations under this clause shall terminate from the date
that Employee first becomes eligible after termination of employment with PPD
for similar coverage under another employer's plan.

                  d. Notwithstanding anything to the contrary in any award
agreement for non-qualified stock options, (i) all unvested shares underlying
PPD non-qualified stock options granted more than six months prior to the date
of Employee's termination shall become fully vested as of the date of Employee's
termination, and (ii) Employee shall continue to be treated under each award
agreement as if he was an employee of PPD until the first to occur of (x) the
third anniversary of Employee's termination of employment, or (y) the expiration
of the exercise period provided for therein; provided, however, in the event of
Employee's death or his disability (as disability is defined in the award
agreement) after the date of Employee's termination of employment hereunder, the
time for exercise after death or such disability prescribed in the award
agreement shall apply. The provisions of this subsection shall also apply to any
and all substitute stock
