                                   ---------


          Robert L. Capizzi, M.D. (hereafter "Dr. Capizzi"), and U.S.

contained, and intending to be legally bound, the parties hereto agree as

follows:


          1.   Dr. Capizzi hereby resigns as an officer of U.S. Bioscience

effective March 4, 1996, but shall continue thereafter through May 31, 1997 (the

employment and any consulting relationship shall terminate at the close of

business on May 31, 1997, without the need of any notice with respect thereto by

either party (except as provided in paragraph 2(h)).


          2.   U.S. Bioscience shall pay and provide to Dr. Capizzi the

following:


               (a)  Salary during the Term of $7,818.46 per pay period, less

                    normal withholding and payroll taxes, to be paid on a bi-

                    weekly pay schedule.


               (b)  Bonus payment for 1995 in an amount equal to twenty-five

               (c)  On the same basis as is provided to senior executives and

                    other employees of U.S. Bioscience, company-paid medical

                    benefits (including health, dental, and prescription drug),

                    less dependent cost, throughout the Term, or until other

                    employer-provided medical insurance is available, which ever

                    occurs first, subject to Dr. Capizzi's right to continue

                    such coverage under COBRA.  In the event that Dr. Capizzi

                    obtains other employment and medical coverage, he will

                    promptly advise U.S. Bioscience.


               (d)  Group life insurance and long term disability benefit during

                    the Term, on the same basis as is provided to senior

                    executives and other employees of U.S. Bioscience.  It is

                    agreed and understood that as of March 4, 1996, Dr. Capizzi

                    will no longer be entitled to participate in U.S.

                    Bioscience's benefit plans for (i) Supplemental Long Term

                    Disability, (ii) Supplemental Life Insurance, (iii) SERP,

                    (iv) 401(k), and (v) Money Purchase Pension Plan; provided

                    that Dr. Capizzi shall continue to be entitled to all

                                      -2-

 
                    benefits available or accrued under such plans through March

                    3, 1996.


               (e)  The right to continue to vest stock options during the Term

                    and the right to a cashless exercise of such vested options

                    during the Term and for a period of three months following

                    the Term.


               (f)  The same rights to indemnification and advancement of

                    expenses as Dr. Capizzi presently has pursuant to U.S.

                    Bioscience's certificate of incorporation and bylaws, or

                    such greater rights as subsequently may be made available to

                    directors and officers of U.S. Bioscience; provided that his

                    right to indemnification as an officer shall be with respect

                    to the period through March 3, 1996.  U.S. Bioscience shall,

                    to the fullest extent not prohibited by law, indemnify Dr.

                    Capizzi for all actions and services provided by him

                    hereunder.  In addition, U.S. Bioscience shall maintain such

                    directors and officers insurance coverage as it may find

                    appropriate, and shall include Dr. Capizzi in his capacity

                    as a director as an additional named insured on any such

                    policy.

                    of U.S. Bioscience common stock at the closing price on the

reasonable efforts to adapt his schedule to comply with U.S. Bioscience's

reasonable request.  Such consulting services may be performed by telephone

written consent of U.S. Bioscience, except as may be necessary in the ordinary

course of performing his duties as an employee of U.S. Bioscience; provided that

this obligation does not apply to any information that becomes published or

otherwise part of the public domain other than through any wrongful act or

omission by Dr. Capizzi.


          8.   All documents, notes and other materials of any nature relating

to any Proprietary Information which are generated by Dr. Capizzi or come into

his possession shall be owned exclusively by U.S. Bioscience.  Dr. Capizzi will

not take any original or copy of the foregoing and will return the same to U.S.

Bioscience upon request.  In addition to the foregoing, Dr. Capizzi will not

publish anything during the Term relating to Proprietary Information without the

written consent of U.S. Bioscience.


          9.   In any action brought by either party for enforcement of the

rights given by this Agreement, the prevailing party shall be entitled to

payment by the other of all reasonable attorneys' fees and costs incurred due to

or resulting from the action.


          10.  In the event of Dr. Capizzi's death prior to the receipt of all

amounts to which he is entitled hereunder, such amounts (including, without

limitation, all amounts due pursuant

beneficiary as Dr. Capizzi shall name by notice to U.S. Bioscience.


          11.  Neither party shall engage in any communications which disparage

or interfere with the other party's existing or prospective business

relationships.


          12.  Neither party shall communicate or disclose the terms of this

Agreement to any person without the prior consent of the other party; provided
                                                                      --------

that Dr. Capizzi may discuss this Agreement with members of his immediate

family, his attorney and his accountant.


          13.  This Agreement embodies the complete understanding and agreement

between U.S. Bioscience and Dr. Capizzi and, other than the Executive Severance

Agreement described below and the option agreements previously issued to Dr.

Capizzi, supersedes any and all prior agreements between them, oral or written,

express or implied, including without limitation the non-competition and

confidentiality provisions of the Employment Agreement dated August 14, 1991 are

superseded by this Agreement, provided that nothing contained in this Agreement

shall supersede the provisions of paragraph 7(c) of such Employment Agreement.

For the sake of clarity, the parties agree that Dr. Capizzi shall not be

prohibited from pursuing research and commercial

                                     -10-

 
development relating to oncology and Acquired Immune Deficiency Syndrome (AIDS)

stimulation and antifols, so long as he does not use any Proprietary Information

of U.S. Bioscience.


          14.  This Agreement shall be governed by the law of the Commonwealth

of Pennsylvania and any suit against U.S. Bioscience or Dr. Capizzi claiming a

breach hereof shall be maintained in a state or federal court in Pennsylvania.


          15.  Nothing in this Agreement is to be construed as an admission or

concession of liability or wrongdoing by either U.S. Bioscience or Dr. Capizzi.


          16.  Dr. Capizzi agrees and represents that:

               (a)  He has read carefully all of the terms of this Agreement;

               (b)  He has been encouraged to review this Agreement with an

                    attorney;

               (c)  He understands the meaning and effect of the terms of this

                    Agreement;

               (d)  He was given up to twenty-one (21) days to determine whether

                    he wishes to enter into this Agreement;

                                     -11-

 
               (e)  He understands that he has seven (7) days from the date of

                    execution of this Agreement to revoke his execution thereof;

               (f)  The entry into and execution of this Agreement is of his own

                    free will and a voluntary act without compulsion of any

                    kind; and

               (g)  No promise or inducement not expressed herein has been made

                    to him.


          17.  U.S. Bioscience hereby represents to Dr. Capizzi that it has all

requisite corporate power and authority to enter into this Agreement and perform

its obligations hereunder, and that this Agreement has been duly authorized,

executed and delivered by U.S. Bioscience and constitutes its legal, valid and

binding obligation, enforceable against it in accordance with its terms.


          18.  If any part or term of this Agreement is subsequently determined

by any court of competent jurisdiction to be unenforceable or illegal, such

determination should not affect the enforceability, legality or binding nature

of any other term or provision of this Agreement.


          19.  The parties to this Agreement are parties to an Executive

Severance Agreement dated October 14, 1991 (the

                                     -12-

 
"Executive Severance Agreement").  Dr. Capizzi agrees that in the event he

becomes eligible to receive compensation under the Executive Severance

Agreement, such compensation shall be reduced by an amount equal to the amount

paid to Dr. Capizzi under this Agreement.  The Executive Severance Agreement

shall cease to be applicable to Dr. Capizzi in accordance with paragraph 2(b) of

the Executive Severance Agreement.


          IN WITNESS WHEREOF, the parties have executed and delivered this

Agreement as of the date first written above.
