ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
ARTICLE VI OF THE CERTIFICATE OF INCORPORATION OF THE REGISTRANT PROVIDES:
 
     SECTION 6.1.  RIGHT TO INDEMNIFICATION.  Each person who was or is made a
party or is threatened to be made a party to or is otherwise involved in any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative, arbitrative or investigative, and whether formal or
informal (hereinafter a "proceeding"), by reason of the fact:
 
          (a) that he or she, or a person of whom he or she is the legal
     representative, is or was a director or Board-elected officer of the
     Corporation, or
 
          (b) that he or she, being at the time a director or Board-elected
     officer of the Corporation, is or was serving at the request of the
     Corporation as a director, trustee, officer, employee or agent of another
     corporation or of a partnership, limited liability company, joint venture,
     trust or other enterprise, including service with respect to an employee
     benefit plan (collectively, "another enterprise" or "other enterprise"),
 
whether either in case (a) or in case (b) the basis of such proceeding is
alleged action or inaction (x) in an official capacity as a director or officer
of the Corporation, or as a director, trustee, officer, employee or agent of
such other enterprise, or (y) in any other capacity related to the Corporation
or such other enterprise while so serving as a director, trustee, officer,
employee or agent, shall be indemnified and held harmless by the Corporation to
the fullest extent permitted by Section 145 of the Delaware General Corporation
Law (or any successor provision or provisions) as the same exists or may
hereafter be amended (but, in the case of any such amendment, with respect to
alleged action or inaction occurring prior to such amendment, only to the extent
that such amendment permits the Corporation to provide broader indemnification
rights than permitted prior thereto), against all expense, liability and loss
(including without limitation attorneys' fees and expenses, judgments, fines,
ERISA excise taxes or penalties and amounts paid in settlement) actually and
reasonably incurred by such person in connection therewith. The persons
indemnified by this Article VI are hereinafter referred to as "indemnitees."
Such indemnification as to such alleged action or inaction shall continue as to
an indemnitee who has after such alleged action or inaction ceased to be a
director or officer of the Corporation, or director, trustee, officer, employee
or agent of such other enterprise; and shall inure to the benefit of the
indemnitee's heirs, executors and administrators. Notwithstanding the foregoing,
except as may be provided in the Bylaws or by the Board of Directors, the
Corporation shall not indemnify any such indemnitee in connection with a
proceeding (or portion thereof) initiated by such indemnitee (but this
prohibition shall not apply to a counterclaim, cross-claim or third-party claim
brought by the indemnitee in any proceeding) unless such proceeding (or portion
thereof) was authorized by the Board of Directors. The right to indemnification
conferred in this Article VI: (i) shall be a contract right; (ii) shall not be
affected adversely as to any indemnitee by any amendment of this Certificate of
Incorporation with respect to any alleged action or inaction occurring prior to
such amendment; and (iii) shall, subject to any requirements imposed by law and
the Bylaws, include the right to be paid by the Corporation the expenses
(including attorneys' fees) incurred in defending any such proceeding in advance
of its final disposition.
 
     SECTION 6.2.  RELATIONSHIP TO OTHER RIGHTS AND PROVISIONS CONCERNING
INDEMNIFICATION.  The rights to indemnification and to the advancement of
expenses conferred in this Article VI shall not be exclusive of any other right
which any person may have or hereafter acquire under this Certificate of
Incorporation, any statute, bylaw, agreement, vote of shareholders or
disinterested directors or otherwise. The Bylaws may contain such other
provisions concerning indemnification, including provisions specifying
reasonable procedures relating to and conditions to the receipt by indemnitees
of indemnification, provided that such provisions are not inconsistent with the
provisions of this Article VI.
 
     SECTION 6.3.  OTHER OFFICERS, EMPLOYEES AND AGENTS.  The Corporation may,
to the extent authorized from time to time by the Board of Directors, grant
rights to indemnification, and to the advancement of
 
                                      II-1
<PAGE>   4
 
expenses, to any other officer, employee or agent of the Corporation (or any
person serving at the Corporation's request as a director, trustee, officer,
employee or agent of another enterprise) or to any person who is or was a
director, officer, employee or agent of any of the Corporation's affiliates,
predecessor or subsidiary corporations or of a constituent corporation absorbed
by the Corporation in a consolidation or merger or who is or was serving at the
request of such affiliate, predecessor or subsidiary corporation or of such
constituent corporation as a director, trustee, officer, employee or agent of
another enterprise, in each case as determined by the Board of Directors to the
fullest extent of the provisions of this Article VI in cases of the
indemnification and advancement of expenses of directors and Board-elected
officers of the Corporation, or to any lesser extent (or greater extent, if
permitted by law) determined by the Board of Directors. If so indemnified, such
persons shall be included in the term "indemnitee" or "indemnitees" as used in
this Article VI and in the Bylaws of the Corporation.
 
ARTICLE VII OF THE BYLAWS OF REGISTRANT PROVIDES:
 
     SECTION 7.01.  INDEMNIFICATION PROVISIONS IN CERTIFICATE OF
INCORPORATION.  The provisions of this Article VII are intended to supplement
Article VI of the Certificate of Incorporation pursuant to Sections 6.2 and 6.3
thereof. To the extent that this Article VII contains any provisions
inconsistent with said Article VI, the provisions of the Certificate of
Incorporation shall govern. Terms defined in such Article VI shall have the same
meaning in this Article VII.
 
     SECTION 7.02.  INDEMNIFICATION OF OTHERS.  The Corporation may indemnify
and advance expenses to its other officers, employees and agents to the same
extent as to its directors and Board-elected officers, as set forth in the
Certificate of Incorporation and in this Article VII of the Bylaws of the
Corporation, and, if so indemnified, such persons shall be included in the term
"indemnitee" or "indemnitees" as used in this Article VII of the Bylaws.
 
     SECTION 7.03.  UNDERTAKINGS FOR ADVANCES OF EXPENSES.  If and to the extent
the Delaware General Corporation Law requires, an advancement by the Corporation
of expenses incurred by an indemnitee pursuant to clause (iii) of the last
sentence of Section 6.1 of the Certificate of Incorporation (hereinafter an
"advancement of expenses") shall be made only upon delivery to the Corporation
of an undertaking (hereinafter an "undertaking"), by or on behalf of such
indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal (hereinafter a "final adjudication") that such indemnitee is not entitled
to be indemnified for such expenses under Article VI of the Certificate of
Incorporation or otherwise.
 
     SECTION 7.04.  CLAIMS FOR INDEMNIFICATION.  If a claim for indemnification
under Section 6.1 of the Certificate of Incorporation is not paid in full by the
Corporation within 60 days after it has been received in writing by the
Corporation, except in the case of a claim for an advancement of expenses, in
which case the applicable period shall be 20 days, the indemnitee may at any
time thereafter bring suit against the Corporation to recover the unpaid amount
of the claim. If the indemnitee is successful in whole or in part in any such
suit, or in a suit brought by the Corporation to recover an advancement of
expenses pursuant to the terms of an undertaking, the indemnitee shall be
entitled to be paid also the expense of prosecuting or defending such suit. In
any suit brought by the indemnitee to enforce a right to indemnification
hereunder (but not in a suit brought by the indemnitee to enforce a right to an
advancement of expenses) it shall be a defense that, and in any suit by the
Corporation to recover an advancement of expenses pursuant to the terms of an
undertaking the Corporation shall be entitled to recover such expenses only upon
a final adjudication that, the indemnitee has not met the applicable standard of
conduct set forth in Section 145 of the Delaware General Corporation Law (or any
successor provision or provisions). Neither the failure of the Corporation
(including the Board of Directors, independent legal counsel, or its
shareholders) to have made a determination prior to the commencement of such
suit that indemnification of the indemnitee is proper in the circumstances
because the indemnitee has met the applicable standard of conduct set forth in
Section 145 of the Delaware General Corporation Law (or any successor provision
or provisions), nor an actual determination by the Corporation (including the
Board of Directors, independent legal counsel, or its shareholders) that the
indemnitee has not met such applicable standard of conduct, shall create a
presumption that the indemnitee has not met the applicable standard of conduct
or, in the case of such a suit brought by the
 
                                      II-2
<PAGE>   5
 
indemnitee, be a defense to such suit. In any suit brought by the indemnitee to
enforce a right to indemnification or to an advancement of expenses hereunder,
or by the Corporation to recover an advancement of expenses pursuant to the
terms of an undertaking, the burden of proving that the indemnitee is not
entitled to be indemnified, or to have or retain such advancement of expenses,
under Article VI of the Certificate of Incorporation or this Article VII or
otherwise, shall be on the Corporation.
 
     SECTION 7.05.  INSURANCE.  The Corporation may maintain insurance, at its
expense, to protect itself and any director, trustee, officer, employee or agent
of the Corporation or another enterprise against any expense, liability or loss,
whether or not the Corporation would have the power to indemnify such person
against such expense, liability or loss under the Delaware General Corporation
Law.
 
     SECTION 7.06.  SEVERABILITY.  In the event that any of the provisions of
this Article VII (including any provision within a single section, paragraph or
sentence) is held by a court of competent jurisdiction to be invalid, void or
otherwise unenforceable, the remaining provisions are severable and shall remain
enforceable to the full extent permitted by law.
 
     Section 145 of the Delaware General Corporation law empowers Vaxcel to
indemnify its officers and directors under certain circumstances. The pertinent
provisions of that statute read as follows:
 
          "(a) A corporation may indemnify any person who was or is a party or
     is threatened to be made a party to any threatened, pending or completed
     action, suit or proceeding, whether civil, criminal, administrative or
     investigative (other than an action by or in the right of the corporation)
     by reason of the fact that he is or was a director, officer, employee or
     agent of the corporation, or is or was serving at the request of the
     corporation as a director, officer, employee or agent of another
     corporation, partnership, joint venture, trust or other enterprise, against
     expenses (including attorneys' fees), judgments, fines and amounts paid in
     settlement actually and reasonably incurred by him in connection with such
     action, suit or proceeding if he acted in good faith and in a manner he
     reasonably believed to be in or not opposed to the best interests of the
     corporation, and, with respect to any criminal action or proceeding, had no
     reasonable cause to believe his conduct was unlawful. The termination of
     any action, suit or proceeding by judgment, order, settlement, conviction,
     or upon a plea of nolo contendere or its equivalent, shall not, of itself,
     create a presumption that the person did not act in good faith and in a
     manner which he reasonably believed to be in or not opposed to the best
     interests of the corporation, and, with respect to any criminal action or
     proceeding, had reasonable cause to believe that his conduct was unlawful.
 
          "(b) A corporation may indemnify any person who was or is a party or
     is threatened to be made a party to any threatened, pending or completed
     action or suit by or in the right of the corporation to procure a judgment
     in its favor by reason of the fact that he is or was a director, officer,
     employee or agent of the corporation, or is or was serving at the request
     of the corporation as a director, officer, employee or agent of another
     corporation, partnership, joint venture, trust or other enterprise against
     expenses (including attorneys' fees) actually and reasonably incurred by
     him in connection with the defense or settlement of such action or suit if
     he acted in good faith and in a manner he reasonably believed to be in or
     not opposed to the best interests of the corporation and except that no
     indemnification shall be made in respect of any claim, issue or matter as
     to which such person shall have been adjudged to be liable to the
     corporation unless and only to the extent that the Court of Chancery or the
     court in which such action or suit was brought shall determine upon
     application that, despite the adjudication of liability but in view of all
     the circumstances of the case, such person is fairly and reasonably
     entitled to indemnity for such expenses which the Court of Chancery or such
     other court shall deem proper.
 
          "(c) To the extent that a director, officer, employee or agent of a
     corporation has been successful on the merits or otherwise in defense of
     any action, suit or proceeding referred to in subsections (a) and (b) of
     this section, or in defense of any claim, issue or matter therein, he shall
     be indemnified against expenses (including attorneys' fees) actually and
     reasonably incurred by him in connection therewith.
 
          "(d) Any indemnification under subsections (a) and (b) of this section
     (unless ordered by a court) shall be made by the corporation only as
     authorized in the specific case upon a determination that indemnification
     of the director, officer, employee or agent is proper in the circumstances
     because he has
 
                                      II-3
<PAGE>   6
 
     met the applicable standard of conduct set forth in subsections (a) and (b)
     of this section. Such determination shall be made (1) by a majority vote of
     the directors who are not parties to such action, suit or proceeding, even
     though less than a quorum, or (2) if there are no such directors, or if
     such directors so direct, by independent legal counsel in a written
     opinion, or (3) by the shareholders.
 
          "(e) Expenses (including attorneys' fees) incurred by an officer or
     director in defending any civil, criminal, administrative or investigative
     action, suit or proceeding may be paid by the corporation in advance of the
     final disposition of such action, suit or proceeding upon receipt of an
     undertaking by or on behalf of such director or officer to repay such
     amount if it shall ultimately be determined that he is not entitled to be
     indemnified by the corporation as authorized in this section. Such expenses
     (including attorneys' fees) incurred by other employees and agents may be
     so paid upon such terms and conditions, if any, as the board of directors
     deems appropriate.
 
          "(f) The indemnification and advancement of expenses provided by, or
     granted pursuant to, the other subsections of this section shall not be
     deemed exclusive of any other rights to which those seeking indemnification
     or advancement of expenses may be entitled under any bylaw, agreement, vote
     of shareholders or disinterested directors or otherwise, both as to action
     in his official capacity and as to action in another capacity while holding
     such office.
 
          "(g) A corporation shall have power to purchase and maintain insurance
     on behalf of any person who is or was a director, officer, employee or
     agent of the corporation, or is or was serving at the request of the
     corporation as a director, officer, employee or agent of another
     corporation, partnership, joint venture, trust or other enterprise against
     any liability asserted against him and incurred by him in any such
     capacity, or arising out of his status as such, whether or not the
     corporation would have the power to indemnify him against such liability
     under this section.
 
          "(h) For purposes of this section, references to 'the corporation'
     shall include, in addition to the resulting corporation, any constituent
     corporation (including any constituent of a constituent) absorbed in a
     consolidation or merger which, if its separate existence had continued,
     would have had power and authority to indemnify its directors, officers,
     and employees or agents, so that any person who is or was a director,
     officer, employee or agent of such constituent corporation, or is or was
     serving at the request of such constituent corporation as a director,
     officer, employee or agent of another corporation, partnership, joint
     venture, trust or other enterprise, shall stand in the same position under
     this section with respect to the resulting or surviving corporation as he
     would have with respect to such constituent corporation if its separate
     existence had continued.
 
          "(i) For purposes of this section, references to 'other enterprises'
     shall include employee benefit plans; references to 'fines' shall include
     any excise taxes assessed on a person with respect to any employee benefit
     plan; and references to 'serving at the request of the corporation' shall
     include any service as a director, officer, employee or agent of the
     corporation which imposes duties on, or involves services by, such
     director, officer, employee or agent with respect to an employee benefit
     plan, its participants or beneficiaries; and a person who acted in good
     faith and in a manner he reasonably believed to be in the interest of the
     participants and beneficiaries of an employee benefit plan shall be deemed
     to have acted in a manner 'not opposed to the best interests of the
     corporation' as referred to in this section.
 
          "(j) The indemnification and advancement of expenses provided by, or
     granted pursuant to, this section shall, unless otherwise provided when
     authorized or ratified, continue as to a person who has ceased to be a
     director, officer, employee or agent and shall inure to the benefit of the
     heirs, executors and administrators of such a person.
 
          "(k) The Court of Chancery is hereby vested with exclusive
     jurisdiction to hear and determine all actions for advancement of expenses
     or indemnification brought under this section or under any bylaw,
     agreement, vote of shareholders or disinterested directors, or otherwise.
     The Court of Chancery may summarily determine a corporation's obligation to
     advance expenses (including attorneys' fees)."
 
     As permitted by applicable statutes, the Registrant has purchased a
standard directors' and officers' liability policy that will, subject to certain
limitations, indemnify the Registrant and its officers and directors
 
                                      II-4
<PAGE>   7
 
for damages they become legally obligated to pay as a result of any negligent
act, error, or omission committed by directors or officers while acting in their
capacities as such.
 
     The indemnification provisions in the Bylaws may be sufficiently broad to
permit indemnification of the Registrant's officers and directors for
liabilities arising under the Securities Act.

ITEM 22.  UNDERTAKINGS.
 
     A. The undersigned Registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this registration statement:
 
             (i) To include any prospectus required by Section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment) which, individually or in the aggregate,
        represent a fundamental change in the information set forth in the
        registration statement. Notwithstanding the foregoing, any increase or
        decrease in volume of securities offered (if the total dollar value of
        securities offered would not exceed that which was registered) and any
        deviation from the low or high end of the estimated maximum offering
        range may be reflected in the form of prospectus filed with the
        Commission pursuant to Rule 424(b)) if, in the aggregate, the changes in
        volume and price represent no more than 20% change in the maximum
        aggregate offering price set forth in the "Calculation of Registration
        Fee" table in the effective registration statement.
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in the registration statement
        or any material change to such information in the registration
        statement.
 
          (2) That, for the purposes of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
     B. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission, such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any
 
                                      II-6
<PAGE>   9
 
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.
 
     C.(1) The undersigned Registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.
 
     (2) The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.
 
     D. The undersigned Registrant hereby undertakes to respond to requests for
information that are incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11, or 13 of this form within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means. This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.
 
     E. The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

         manufacturer is unwilling or unable to supply the Copolymer, then
         Vaxcel and/or its sublicensees shall have the right to make or have
         made the Copolymer.  In such instance, CytRx agrees to make
         appropriate manufacturing know how available to Vaxcel or its
         designee.

2.2      Production Forecasts.  Vaxcel will deliver to CytRx, on the first day
         of each calendar quarter, a requirements forecast indicating Vaxcel's
         monthly requirements for quantities of the Copolymer during the twelve
         (12) months, beginning with the next calendar month.  The specified
         quantities for the first four (4) months of each 12-month forecast
         shall be deemed a firm purchase commitment for such quantities and
         shall be documented by purchase order per section 2.3 of this
         Agreement.  CytRx shall not accept any production forecasts from
         Vaxcel sublicensees.

2.3      Purchase Orders  

                 (a)  Vaxcel shall submit a purchase order for Copolymer at
                 least 120 days prior to the shipment specified in the order.
                 The purchase order shall constitute a firm commitment by
                 Vaxcel to purchase the Copolymer.

                 (b)  The parties understand the potential seasonal nature of
                 requirements for the Copolymer.  In order to ensure adequate
                 lead time for significant increases in requirements, Vaxcel
                 shall submit a firm commitment purchase order at least 210
                 days in advance of requesting shipment of Copolymer greater
                 than 125% of the average monthly quantity shipped over the
                 preceding twelve months.

                 (c)  All orders for Copolymer shall be ordered in full batches
                 from one of   the following Batch Categories:

                       "Small Pilot"                  X X X kilograms
                       "Large Pilot"                  greater than X kilograms
                       "Small Commercial"             greater than XX kilograms
                       "Large Commercial"             greater than XX kilograms

                 (d)  CytRx shall from time to time provide Vaxcel with batch
                 sizes available within each Batch Category. CytRx shall
                 consult with Vaxcel prior to changing batch sizes.

2.4      Price.

                 (a)  The Purchase Price ("Purchase Price") for quantities of
                 Copolymer will be determined by Batch Category.  Batch
                 Category Purchase Prices as of January 1, 1995 is made part of
                 this Agreement as Exhibit B hereto.

                 (b)  The Purchase Price shall automatically be increased or
                 decreased as of January 1 of each year based on the percentage
                 change up or down in the Producer Price Index (PPI) as
                 reported by the U.S. Department of Labor over the immediately
                 preceding twelve months.("the PPI Change Percent").  The
                 initial base year for this price adjustment shall be 1995.
                 The Purchase Price shall be adjusted as follows:  The Purchase
                 Price multiplied by the PPI Change Percent equals the amount
                 of change in the Purchase Price ("the Adjustment Amount").
                 Where the PPI has increased, the Adjustment amount shall be
                 added to the Purchase Price; where the PPI has decreased, the
                 Adjustment Amount shall be subtracted from the Purchase Price

2.5      Payment

                 (a)  CytRx shall invoice Vaxcel for the Purchase Price of the
                 Copolymer when shipped.  Each shipment of Copolymer shall
                 constitute a separate sale obligating Vaxcel to pay therefor.
                 Each CytRx invoice shall be due and payable within thirty (30)
                 days after the date thereof.  Payments received after the due
                 date shall be subject to penalty for late payment accruing
                 from the date of shipment at Prime Rate plus two percent
                 calculated on the total invoice amount.

                 (b)  All payments shall be made in legal currency of the
                 United States of America, by corporate check to CytRx at the
                 address specified in Section 5.3 hereof.

2.6      Shipping Requirements.

                 (a)  CytRx will choose a commercially reasonable method of
                 shipment and a carrier for each shipment of Copolymer unless
                 Vaxcel has specified a particular method of shipment in its
                 purchase order.  Title and risk of loss, delay or damage in
                 transit shall pass to Vaxcel upon delivery by CytRx of the
                 Copolymer to a common carrier or other means of transport at
                 the Manufacturing Facility.  All purchase orders shall be
                 designated FOB point of origin.

                 (b)  If Vaxcel takes delivery at the Manufacturing Facility,
                 title and risk of loss, delay or damage shall pass to Vaxcel
                 upon actual delivery.  Should Vaxcel request, and CytRx agree
                 to storage by CytRx of Copolymer so delivered, such storage
                 shall be at Vaxcel's expense.

                 (c)  Vaxcel at its option may specify direct delivery by CytRx
                 of all or part of a batch to a third party as designated by
                 Vaxcel.  All third party designated shipments shall have the
                 full drop shipment address indicated on the purchase order.

                 (d)  Vaxcel shall promptly reimburse CytRx in U.S. currency
                 for the costs of insurance and freight with respect to the
                 Copolymer, FOB  the Manufacturing Facility.  Vaxcel shall
                 provide CytRx, on request, with properly completed exemption
                 certificates for any tax from which Vaxcel claims exemption.

                 (e)  Vaxcel shall be responsible for payment of any tariffs,
                 customs duty or similar costs and fees associated with the
                 shipment of Copolymer to Vaxcel or to a third party designated
                 by Vaxcel.

                 (f)  CytRx shall make reasonable efforts to deliver Copolymer
                 as specified in the purchase order.  However, any shipment by
                 CytRx of Copolymer





                                     Page 4
<PAGE>   5
                 within the following variances shall constitute compliance by
                 CytRx with the applicable purchase order requirements:

                          (i)  the quantity in kilograms may vary by plus or
                 minus 10% from the batch sizes specified on each purchase 
                 order; and

                          (ii)  the delivery date may vary plus or minus 30
                 days from the date specified in the purchase order.

2.7      Warranties.  CytRx warrants that each shipment of the Copolymer shall
         be manufactured, temporarily stored, packaged, labeled, and controlled
         by CytRx in accordance with the Specifications, the Manufacturing
         Procedures and applicable FDA Standards.  EXCEPT AS SET FORTH IN THE
         PRECEDING SENTENCE, CYTRX MAKES NO EXPRESS OR IMPLIED WARRANTIES,
         STATUTORY OR OTHERWISE, CONCERNING THE PRODUCT.  SPECIFICALLY, BUT
         WITHOUT LIMITING THE FOREGOING, CYTRX MAKES NO EXPRESS OR IMPLIED
         WARRANTY OF MERCHANTABILITY, FITNESS (FOR A PARTICULAR PURPOSE OR
         OTHERWISE), QUALITY OR USEFULNESS OF THE PRODUCT.  CYTRX SHALL IN NO
         EVENT BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES INCURRED
         BY VAXCEL.

2.8      Quality Assurance Requirements

                 (a)  Concurrent with each shipment, CytRx will provide to
                 Vaxcel a Certificate of Analysis that the Copolymer conforms
                 to the Specifications.

                 (b)  CytRx will provide Vaxcel with sufficient samples of each
                 production run of the Copolymer as Vaxcel may reasonably
                 request.

                 (c)  CytRx will not modify the Specifications or any of the
                 Manufacturing Procedures without obtaining the prior consent
                 of Vaxcel, which consent shall not be unreasonably withheld,
                 and/or appropriate regulatory authorities.

2.9      Testing and Rejection of the Copolymer.

                 (a)  CytRx shall conduct the testing of the Copolymer before
                 shipment using the validated analytical methodology specified
                 in Exhibit C, and shall provide Vaxcel with a certification of
                 the test results.  Vaxcel may either accept the Copolymer
                 based on the CytRx test results or may elect to test samples
                 of the corresponding production run using the approved testing
                 methodology per Exhibit C.

                 (b)  Within 30 days after receipt of each shipment of
                 Copolymer by CytRx, Vaxcel or its designee shall have the
                 right to reject any shipment





                                     Page 5
<PAGE>   6
                 that fails to meet the applicable Specifications or FDA
                 Standards. Vaxcel's right of rejection may be exercised by
                 delivery of notice to CytRx within the 30 day period,
                 identifying the rejected Copolymer by production lot number
                 and  stating the basis for rejection.  If Vaxcel does not
                 reject the shipment within 30 days, it will be deemed to have
                 accepted the shipment.  Upon the request of CytRx, Vaxcel
                 shall furnish evidence of nonconformity of the shipment of
                 Copolymer.  If CytRx disagrees with Vaxcel's determination,
                 the parties shall submit the dispute to a mutually acceptable
                 laboratory for a binding determination of the conformity or
                 nonconformity of the Copolymer.  The nonprevailing party shall
                 pay the costs and expenses of the laboratory tests.  If Vaxcel
                 properly rejects the Copolymer, Vaxcel shall receive a credit
                 for any amounts already paid to CytRx for the rejected
                 Copolymer against the Purchase Price for the next shipment of
                 Copolymer accepted by Vaxcel, or shall be reimbursed for such
                 payment with interest at the prevailing prime rate per annum
                 at the option of CytRx.  Vaxcel shall be responsible for the
                 destruction of all rejected Copolymer (in compliance with
                 applicable law) or the return of the shipment, at the expense
                 of CytRx, at the discretion of CytRx.

                 (c) If Vaxcel or its designee rejects a shipment per section
                 2.9(b), at Vaxcel's request, CytRx shall use every reasonable
                 effort to provide an equivalent quantity in a timely fashion
                 to replace the batch in question until such time as a
                 definitive disposition of the batch in question is
                 forthcoming.  The terms and conditions of this Agreement shall
                 apply for this provisional quantity.

                 (d)  Vaxcel shall be responsible for all stability testing of
                 the Copolymer.  If so requested by Vaxcel, CytRx shall pull
                 samples of Copolymer for stability testing purposes, and shall
                 ship such samples at Vaxcel's expense in accord with
                 instructions from Vaxcel.

2.10     Record Keeping.  CytRx will maintain the manufacturing, production and
         control records for the Copolymer for the periods required by
         applicable FDA Standards and, in any event, will provide Vaxcel the
         opportunity to take possession of such records before they are
         destroyed.

2.11     Regulatory Approvals.  CytRx shall obtain and maintain any
         establishment license, facility license or other license,
         authorization or approval required by the FDA or any other federal,
         state or local governmental authority for the manufacture of the
         Copolymer as contemplated hereunder.  Vaxcel shall reimburse CytRx for
         meeting any additional requirements imposed by international
         regulatory agencies.

2.12     Manufacturing Information.  CytRx hereby grants Vaxcel permission to
         reference CytRx's Drug Manufacturing File (DMF) concerning the
         manufacture of the Copolymer as shall be required by Vaxcel to obtain
         regulatory approvals.

2.13     Compliance with Laws.  Vaxcel and its sublicensees shall comply with
         all applicable laws in the manufacture of finished product using the
         Copolymer and in the promotion, marketing and sale of all such
         products.

2.14     Notification.  Vaxcel shall notify CytRx of any adverse or unexpected
         results, or any potential government action relevant to the Copolymer.

                 (a)  breach by the other party of any covenant (other than a
                 payment covenant covered by Section 3.2) or of any
                 representation or warranty contained in this Agreement that is
                 continuing sixty (60) calendar days after the non-breaching
                 party gives the breaching party written notice of such breach;
                 or

                 (b)  the non-terminating party becomes insolvent, or voluntary
                 or involuntary proceedings by or against the non-terminating
                 party are instituted in bankruptcy or under any insolvency
                 law, or a receiver or custodian is appointed for the non-
                 terminating party, or proceedings are instituted by or against
                 the non-terminating party for corporate reorganization or the
                 dissolution of the non-terminating party, which proceedings,
                 if involuntary, shall not have been dismissed within sixty
                 (60) days after the date of filing, or the non-terminating
                 party makes an assignment for the benefit of creditors;  or

                 (c)  The cessation of operations by the non-terminating party

<PAGE>   8
                 terminating party is not the surviving corporation or a sale
                 by the non-terminating party of all or substantially all of
                 its assets); or

                 (d)  the seizure or attachment of all or substantially all of
                 the assets of the non-terminating party, in conjunction with

                 faith by the non-terminating party.

         Upon the occurrence of any Event of Default (as defined in the License
         Agreement), CytRx shall have the right to terminate this Agreement by
         giving written notice of termination, such termination to be effective
         with the giving of such notice.

         No exercise by CytRx of any right of termination will constitute a
         waiver of any right of CytRx for recovery of any moneys then due to it
         hereunder or any other right or remedy it may have by law or by this
         Agreement.

3.4      Survival.  Notwithstanding the termination of this Agreement, however
         caused, Vaxcel's obligations to pay for Copolymer shipped prior the
         date of termination shall survive such termination until satisfied in
         full.  In addition, Article IV and any other provisions required to
         interpret this Agreement shall survive the termination of this
         Agreement to the extent required for the full observation and
         performance of the surviving terms and rights and obligations of the
         parties arising prior to the termination hereof.

                                 MISCELLANEOUS

5.1      Representations of the Parties.  Each party represents and warrants to
         the other party that this Agreement has been duly authorized, executed
         and delivered and that the performance of its obligations under this
         Agreement does not conflict with any order, law, rule or regulation or
         any agreement or understanding by which such party is bound.

5.2      Force Majeure.  Failure of CytRx to make, or Vaxcel to take, any one
         or more deliveries when due, if caused by fire, storms, floods,
         strikes, lockouts, accidents, war, riots or civil commotions,
         inability to obtain railroad cars or raw materials, embargoes, any
         State or Federal regulation, law, or restriction, seizure or
         acquisition of Copolymer by the Government of the United States or of
         any state, or of any agency thereof or by reason of any compliance
         with a demand or request for such product for any purpose for national
         defense, or any other cause or contingency beyond the reasonable
         control of said party (whether or not of the same kind or nature as
         the causes or contingencies above enumerated) shall not subject the
         party so failing to any liability to the other, and the total contract
         quantity shall be reduced to the extent of the deliveries so omitted.

5.3      Notices.  Any notice or other communication required or permitted to
         be made or given to either party hereto pursuant to this Agreement

5.4      Entire Agreement;  Amendment.  This Agreement, together with the
         Exhibits annexed hereto sets forth and constitutes the entire
         agreement between the parties hereto with respect to the subject
         matter hereof, and supersedes any and all prior agreements,
         understandings, promises, and representations made by either party to
         the other concerning the subject matter hereof and the terms
         applicable hereto.  This Agreement may not be released, discharged,
         amended or modified in any





                                    Page 10
<PAGE>   11
         manner except by an instrument in writing signed by duly authorized
         representatives of Vaxcel and CytRx.

5.5      Parties Independent.  In making and performing this Agreement, the
         parties act and shall act at all times as independent entities and
         nothing contained in this Agreement shall be construed or implied to
         create an agency, partnership or employer and employee relationship
         between Vaxcel and CytRx.  Except as specifically provided herein, at
         no time shall either party make commitments or incur any charges or
         expenses for or in the name of the other party.

5.6      Governing Law.  This Agreement shall be deemed to have been entered
         into and shall be construed and enforced in accordance with the laws
         of the State of Delaware.

5.7      Waivers.  The failure of either party to insist, in any one or more
         instances, upon the performance of any of the terms, covenants or
         conditions of this Agreement and to exercise any right hereunder,
         shall not be construed as a waiver or relinquishment of the future
         performance of any such term, covenant or condition or the future
         exercise of such right, but the obligations of the other party with
         respect to such future performance shall continue in full force and
         effect.

5.8      Headings.  The headings of the articles, sections and paragraphs used
         in this Agreement are included for convenience only and are not to be
         used in construing or interpreting this Agreement.

5.9      Assignability.  This Agreement shall not be assignable by either party
         without the prior written consent of the other party, except that such
         consent is not required in connection with the assignment of either
         party's rights or obligations hereunder to an Affiliate thereof.

5.10     Effect of Invalidity of Certain Provisions.  Any term or provision of
         this Agreement which is invalid or unenforceable in any jurisdiction
         shall, as to such jurisdiction, be ineffective to the extent of such
         invalidity or unenforceability without rendering invalid or
         unenforceable the remaining terms and provisions of this Agreement.

5.11     Counterparts.  This Agreement shall become binding when any one or
         more counterparts hereof, individually or taken together, shall bear
         the signatures of each of the parties hereto.  This Agreement may be
         executed in any number of counterparts, each of which shall be an
         original as against either party whose signature appears thereon, but
         all of which together shall constitute but one and the same
         instrument.

5.12     Additional Copolymers.  If Vaxcel requests CytRx to synthesize and
         supply a copolymer(s) different than CRL-1005 (including CRL-1005
         synthesized by SCF process) in the Field as defined in the License
         Agreement, CytRx will offer to





                                    Page 11
<PAGE>   12
         supply such copolymer(s) to Vaxcel upon terms substantially similar to
         those set forth in this Agreement if they are substantially similar in
         structure and require similar manufacturing procedures with similar
         cost.  In the event the cost of CytRx supplying such copolymer(s) to
         Vaxcel is not similar to CRL-1005 or involves other manufacturing
         processes (such as SCF), the parties will negotiate a revised Purchase
         Price and all other terms of this Agreement will remain substantially
         unchanged.  Quantities of such copolymer(s) for initial evaluation and
         testing shall be subject to increased costs for experimental
         synthesis, development, scale-up, and documentation of manufacturing
         processes.

5.13     Agreement not to Solicit.  Vaxcel agrees that during the term of this
         Agreement and for a period of five years following the termination of
         the Agreement that it will not, either directly or indirectly, on
         Vaxcel's behalf or on behalf of others, solicit or attempt to solicit
         for the purpose of being employed any person then employed in chemical
         synthesis or manufacturing by CytRx or its Affiliates, whether or not
         employment of any such person is pursuant to a written agreement, for
         a determined period or at will.

5.14     Confidentiality.
                 (a)  Vaxcel agrees that during the term of this Agreement and
                 for a period of five years following the termination of the
                 Agreement to keep all technical information regarding the
                 Copolymer in trust and confidence and not to disclose to
                 others, nor to use for any purpose other than that
                 specifically outlined in this Agreement and the License
                 Agreement.  This agreement of confidentiality includes
                 information received in writing or verbally, whether received
                 intentionally or unintentionally, during the course of
                 Vaxcel's business with CytRx, its Affiliates, or its third
                 party subcontractors.

                 (b)  CytRx agrees that during the term of this Agreement and
                 for a period of five years following the termination of the
                 Agreement to keep all information gained in administering the
                 Agreement in trust and confidence and not to disclose to
                 others, nor to use for any purpose other than that
                 specifically outlined in this Agreement and the License
                 Agreement.  This agreement of confidentiality includes
                 information received in writing or verbally, whether received
                 intentionally or unintentionally, during the course of CytRx's
                 business with Vaxcel, its Affiliates, or its sublicensees.

IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement as of
the date first above written.
