                        SETTLEMENT AND RELEASE AGREEMENT

            This Settlement and Release Agreement ("Agreement") is made and
entered into as of May 10, 2004 (the "Effective Date"), by and between CytRx
Corporation, a Delaware corporation (the "Company"), and MBN Consulting, LLC, a
Florida limited liability company ("MBN"), with respect to the following facts:

                                    RECITALS

            A. The Company and MBN entered into a Consulting Agreement, dated as
of December 1, 2003 (the "Consulting Agreement"), whereby MBN was to represent
the Company on a non-exclusive basis in investors' communications and to consult
with management concerning the Company's activities.

            B. Pursuant to the Consulting Agreement, the Company has paid to MBN
$20,000 in cash consulting fees and issued a warrant to MBN to purchase 600,000
shares of the Company's common stock, $0.01 par value ("Common Stock"), at a
purchase price per share of $2.25 per share, with such warrant being vested and
exercisable as to 100,000 shares of the Company's Common Stock as of December 1,
2003, and the balance of 500,000 shares exercisable upon the Company meeting
certain requirements for listing of its Common Stock on the Nasdaq National
Market on or before June 30, 2004 (the "Original Warrant").

            C. Thereafter, various disputes ensued among the parties, and thus
the parties now seek to terminate the Consulting Agreement and enter into this
Agreement to settle fully and finally, in the manner set forth herein, all
differences between them which have arisen, or which may arise, prior to, or at
the time of the execution of this Agreement, including any and all claims and
controversies arising out of the Consulting Agreement.

            NOW, THEREFORE, in consideration of the premises and promises
contained in this Agreement, the sufficiency of which the parties hereto
acknowledge, the parties hereto hereby agree as follows:

            1. SETTLEMENT AND TERMINATION OF CONSULTING AGREEMENT. Upon
execution of this Agreement, (a) MBN shall forgive any and all sums due and owed
by the Company under the Consulting Agreement; (b) MBN shall retain the $20,000
the Company has previously paid pursuant to the Consulting Agreement and (c) the
Consulting Agreement shall be considered terminated in its entirety as of the
Effective Date. The foregoing arrangements shall be in complete satisfaction and
extinction of all obligations of all parties hereto to the others incurred in
connection with the Consulting Agreement.

            2. ORIGINAL WARRANT. Upon execution of this Agreement, (a) MBN shall
return the Original Warrant to the Company; (b) the Company shall issue a fully
executed replacement warrant for the purchase of the 100,000 vested shares MBN
is previously entitled to subject to the same terms and conditions as currently
exist in the Original Warrant; and (c) the right to purchase the additional
500,000 shares of Common Stock as contained in the Original Warrant shall be
terminated and extinguished in its entirety.

PARTIES. Without limiting the generality of Section 3 above, the Company and
MBN, on behalf of the Company Releasing Parties and MBN Releasing Parties
respectively, expressly release any and all past, present and future claims in
connection with the Released Matters which the Company, MBN or any of the
Releasing Parties does not know of or suspect to exist in their favor, whether
through ignorance, oversight, error, negligence or otherwise, and which, if
known, would materially affect the Company's or MBN's decision to enter into
this Agreement, and to this end the Company and MBN, on behalf of the Releasing
Parties, hereby waive all rights under Section 1542 of the California Civil Code
which states in full as follows:

            "A general release does not extend to claims which the creditor does
            not know or suspect to exist in his favor at the time of executing
            the release, which if known by him must have materially affected his
            settlement with the debtor."

            The Company and MBN represent, warrant and agree that in entering
into this Agreement, they are not relying and have not relied upon any
representation, promise or statement made by anyone which is not recited,
contained or embodied in this Agreement. The Company and MBN understand and
expressly assume the risk that any fact not recited, contained or embodied
herein may turn out hereafter to be other than, different from or contrary to
the facts now known to him or believed by him to be true. Nevertheless, the
Company and MBN intend by this Agreement, and with the advice of their own
independently selected counsel and on behalf of the Releasing Parties, to
release fully, finally and forever the Released Matters and agree that this
Agreement shall be effective in all respects notwithstanding any such difference
in facts and shall not be subject to termination, modification or rescission by
reason of any such difference in facts.

            7. NO ASSIGNMENT OR TRANSFER OF CLAIMS. Both the Company and MBN
hereby represent and warrant that they have not heretofore assigned or
transferred, or purported to assign or transfer, to any person or entity,
whether by act, operation of law or otherwise, all or any part of or any
interest in any claim, contention, demand or cause of action relating to the
Released Matter or any interest in the Original Warrant. The Company and MBN
hereby agree to indemnify, defend and hold the Released Parties harmless from
and against any claim, contention, demand, cause of action, obligation and
liability of any nature, character or description whatsoever, including the
payment of attorneys' fees and costs actually incurred, whether or not
litigation is commenced, which may be based upon or which may arise out of or in
connection with any such assignment or transfer or purported assignment or
transfer.

            8. NO WRONGDOING. The parties understand and agree that neither the
execution nor delivery of this Agreement by any party nor the receipt of any
consideration by any party incident to this Agreement is an admission of any
wrongdoing whatsoever on the part of any of the Released Parties.

LIMITED TO LOST PROFITS, EVEN IF SUCH PARTIES HAVE BEEN APPRISED OF THE
LIKELIHOOD THEREOF.

            10. CONFIDENTIAL INFORMATION. MBN understands and agrees that while

and that it is and shall remain the exclusive property of the Company, and, to

and shall cause its respective directors, officers, members, managers, employees
and affiliates not to, directly or indirectly, make known, divulge, reveal,

Company within 15 days after delivery of any such notice by the Company, of the

efforts to cause all such Registrable Shares of the Holder delivering such
notice that are not already covered by an effective registration statement to be
included in the Registration Statement on the same terms and conditions as the
securities otherwise being sold in such registration; provided, however, that if
the managing underwriter for the offering covered by the Registration Statement
advises the Company that the inclusion of all Registrable Securities requested
to be included in such registration would interfere with the successful
marketing (including pricing) of the Primary Shares or Other Shares proposed to
be registered by the Company, then the number of Primary Shares, Registrable
Securities and Other Shares proposed to be included in such registration shall
be included in the following order:

                  (ii) second, the Registrable Securities and Other Shares
requested to be included in such registration (or, if necessary, such
Registrable Securities and Other Shares pro rata among the holders thereof based
upon the number of Registrable Securities and Other Shares requested to be
registered by each such holder); or

            (b) if the Company proposes to register Other Shares pursuant to a
request for registration by the holders of such Other Shares:

registration;

                  (ii) second, the Registrable Securities and Other Shares

                  (iii) third, the Primary Shares.

      3. Registration Procedures; Company's Obligations.

            In connection with the registration of the Registrable Securities,
the Company shall:

            (a) Prepare and file with the Commission the Registration Statement
on Form S-3 (or if the Company is not then eligible to register for resale the
Registrable Securities on Form S-3 such registration shall be on another
appropriate form in accordance with the Securities Act and the Rules promulgated
thereunder) in accordance with the method or methods of distribution thereof as
specified by the Holder (except if otherwise directed by the Holder), and use
its commercially reasonable best efforts to cause the Registration Statement to
become effective and remain effective for a period of two years from the
effective date of the Registration Statement as provided herein; provided,
however, that not less than two (2) Business Days prior to the filing of the
Registration Statement or any related Prospectus or any amendment or supplement
thereto (including any document that would be incorporated therein by
reference), the Company shall (i) furnish to the Holder and any Special Counsel,
copies of all such documents proposed to be filed, which documents (other than
those incorporated by reference) will be subject to the timely review of and
comment by such Special Counsel, and (ii) at the request of the Holder cause its
officers and directors, counsel and independent certified public accountants to
respond to such inquiries, and to make available for inspection by the Holder
all financial and other records, pertinent corporate documents and properties of
the Company, as shall be necessary, in the reasonable opinion of such Special
Counsel, to conduct a reasonable investigation within the meaning of the
Securities Act. The Company shall not file the Registration Statement or any
such Prospectus or any amendments or supplements thereto to which the Holder or
any Special Counsel shall reasonably object in writing within two (2) Business
Days of their receipt thereof.

            (b) (i) Prepare and file with the Commission such amendments,
including post-effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the

                                      -4-
<PAGE>

two-year period from the effective date of the Registration Statement; (ii)
cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond promptly to any comments received from the
Commission with respect to the Registration Statement or any amendment thereto
and promptly provide the Holder true and complete copies of all correspondence
from and to the Commission relating to the Registration Statement; and (iv)
comply in all material respects with the provisions of the Securities Act and
the Exchange Act with respect to the disposition of all Registrable Securities
covered by the Registration Statement during the applicable period in accordance
with the intended methods of disposition by the Holder set forth in the
Registration Statement as so amended or in such Prospectus as so supplemented.

            (c) Notify the Holder of Registrable Securities to be sold and any
Special Counsel promptly (and, in the case of (i)(A) below, not less than two
(2) Business Days prior to such filing and, in the case of (i)(C) below, no
later than the first Business Day following the date on which the Registration
Statement becomes effective) and (if requested by any such Person) confirm such
notice in writing no later than two (2) Business Days following the day (i)(A)
when a Prospectus or any Prospectus supplement or post-effective amendment to
the Registration Statement is proposed to be filed, (B) when the Commission
notifies the Company whether there will be a "review" of such Registration
Statement and whenever the Commission comments in writing on such Registration
Statement, and (C) with respect to the Registration Statement or any
post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) of the receipt by the Company of any notification with respect to
the suspension of the qualification or exemption from qualification of any of
the Registrable Securities for sale in any jurisdiction, or the initiation or
threatening of any Proceeding for such purpose; and (v) of the occurrence of any
event that makes any statement made in the Registration Statement or Prospectus
or any document incorporated or deemed to be incorporated therein by reference
untrue in any material respect or that requires any revisions to the
Registration Statement, Prospectus or other documents so that, in the case of
the Registration Statement or the Prospectus, as the case may be, it will not
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.

            The Company shall promptly furnish to the Special Counsel, without
charge, (i) any correspondence from the Commission or the Commission's staff to
the Company or its representatives relating to any Registration Statement, and
(ii) promptly after the same is prepared and filed with the Commission, a copy
of any written response to the correspondence received from the Commission.

            (d) Use its commercially reasonable best efforts to avoid the
issuance of, or, if issued, obtain the withdrawal of, (i) any order suspending
the effectiveness of the Registration

                                      -5-
<PAGE>

Statement, or (ii) any suspension of the qualification (or exemption from
qualification) of any of the Registrable Securities for sale in any U.S.
jurisdiction, at the earliest practicable moment.

            (e) If requested by the Holder, (i) promptly incorporate in a
Prospectus supplement or post-effective amendment to the Registration Statement
such information as the Company reasonably agrees should be included therein,
and (ii) make all required filings of such Prospectus supplement or such
post-effective amendment as soon as practicable after the Company has received
notification of the matters to be incorporated in such Prospectus supplement or
post-effective amendment.

            (f) Furnish to the Holder and any Special Counsel, without charge,
at least one conformed copy of each Registration Statement and each amendment
thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

            (g) Promptly deliver to the Holder and any Special Counsel, without
charge, as many copies of the Registration Statement, Prospectus or Prospectuses
(including each form of prospectus) and each amendment or supplement thereto as
such Persons may reasonably request; and the Company hereby consents to the use
of such Prospectus and each amendment or supplement thereto by the selling
Holder in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto.

            (h) Prior to any public offering of Registrable Securities, use its
commercially reasonable best efforts to register or qualify or cooperate with
the selling Holder and any Special Counsel in connection with the registration
or qualification (or exemption from such registration or qualification) of such
Registrable Securities for offer and sale under the securities or Blue Sky laws
of such jurisdictions within the United States as the Holder reasonably requests
in writing, to keep each such registration or qualification (or exemption
therefrom) effective during the two-year period from the effective date of the
Registration Statement and to do any and all other acts or things necessary or
advisable to enable the disposition in such jurisdictions of the Registrable
Securities covered by the Registration Statement; provided, however, that the
Company shall not be required to qualify generally to do business in any
jurisdiction where it is not then so qualified or to take any action that would
subject it to general service of process in any such jurisdiction where it is
not then so subject or subject the Company to any tax in any such jurisdiction
where it is not then so subject.

            (i) Cooperate with the Holder to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be sold
pursuant to the Registration Statement and to enable such Registrable Securities
to be in such denominations and registered in such names as the Holder may
request at least two (2) Business Days prior to any sale of Registrable
Securities.

            (j) Upon the occurrence of any event contemplated by Section
3(c)(v), promptly prepare a supplement or amendment, including a post-effective
amendment, to the Registration Statement or a supplement to the related
Prospectus or any document incorporated

                                      -6-
<PAGE>

or deemed to be incorporated therein by reference, and file any other required
document so that, as thereafter delivered, neither the Registration Statement
nor such Prospectus will contain an untrue statement of a material fact or omit
to state a material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading.

            (k) Use its commercially reasonable best efforts to cause all
Registrable Securities relating to such Registration Statement to be quoted by
NASDAQ or any other securities exchange, quotation system, market or
over-the-counter bulletin board, if any, on which the same securities issued by
the Company are then listed.

            (l) Comply in all material respects with all applicable rules and
regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions of Section 11(a) of the
Securities Act and Rule 158 not later than forty-five (45) days after the end of
any twelve (12) month period (or ninety (90) days after the end of any twelve
(12) month period if such period is a fiscal year) commencing on the first day
of the first fiscal quarter of the Company after the effective date of the
Registration Statement, which statement shall conform to the requirements of
Rule 158.

            (m) If (i) there is material non-public information regarding the
Company which the Company's Board of Directors (the "Board") reasonably
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably determines not to be in the Company's
best interest to disclose and which the Company would be required to disclose
under the Registration Statement, then the Company may suspend effectiveness of
the Registration Statement and suspend the sale of Registrable Securities under
the Registration Statement one (1) time every three (3) months or three (3)
times in any twelve month period, provided that the Company may not suspend its
obligation for more than sixty (60) days in the aggregate in any twelve month
period (each, a "Blackout Period"); provided, however, that no such suspension
shall be permitted for more than twenty (20) consecutive days, arising out of
the same set of facts, circumstances or transactions, and that there shall be at
least two business days between each Blackout Period.

            (n) Within two (2) Business Days after the Registration Statement
which includes the Registrable Securities is ordered effective by the
Commission, the Company shall deliver, and shall cause legal counsel for the
Company to deliver, to the transfer agent for such Registrable Securities (with
copies to the Holder whose Registrable Securities are included in such
Registration Statement) confirmation that the Registration Statement has been
declared effective by the Commission in the form attached hereto as Exhibit B.

      4. Registration Procedures; Holder's Obligations

            In connection with the registration of the Registrable Securities,
the Holder shall:

                                      -7-
<PAGE>

            (a) If the Registration Statement refers to the Holder by name or
otherwise as the holder of any securities of the Company, have the right to
require (if such reference to the Holder by name or otherwise is not required by
the Securities Act or any similar federal statute then in force) the deletion of
the reference to the Holder in any amendment or supplement to the Registration
Statement filed or prepared subsequent to the time that such reference ceases to
be required.

            (b) (i) not sell any Registrable Securities under the Registration
Statement until it has received copies of the Prospectus as then amended or
supplemented as contemplated in Section 3(g) and notice from the Company that
such Registration Statement and any post-effective amendments thereto have
become effective as contemplated by Section 3(c), (ii) comply with the
prospectus delivery requirements of the Securities Act as applicable to it in
connection with sales of Registrable Securities pursuant to the Registration
Statement, and (iii) furnish to the Company information regarding such Holder
and the distribution of such Registrable Securities as is required by law to be
disclosed in the Registration Statement, and the Company may exclude from such
registration the Registrable Securities of the Holder if it fails to furnish
such information within a reasonable time prior to the filing of each
Registration Statement, supplemented Prospectus and/or amended Registration
Statement.

            (c) upon receipt of a notice from the Company of the occurrence of
any event of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv),
3(c)(v) or 3(m), forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until the Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(j), or until it is advised in writing by the Company
that the use of the applicable Prospectus may be resumed, and, in either case,
has received copies of any additional or supplemental filings that are
incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

      5. Registration Expenses

            All reasonable fees and expenses incident to the performance of or
compliance with this Agreement by the Company shall be borne by the Company
whether or not the Registration Statement is filed or becomes effective and
whether or not any Registrable Securities are sold pursuant to the Registration
Statement. The fees and expenses referred to in the foregoing sentence shall
include, without limitation, the following: (i) all registration and filing fees
(including, without limitation, fees and expenses (A) with respect to filings
required to be made with NASDAQ and each securities exchange or other market on
which Registrable Securities are required hereunder to be listed, (B) with
respect to filings required to be made with the Commission, and (C) in
compliance with state securities or Blue Sky laws); (ii) printing expenses
(including, without limitation, expenses of printing certificates for
Registrable Securities and of printing prospectuses if the printing of
prospectuses is requested by the holders of a majority of the Registrable
Securities included in the Registration Statement); (iii) messenger, telephone
and delivery expenses incurred by the Company; (iv) fees and disbursements of
counsel for the Company; and (v) fees and expenses of all other Persons retained
by the Company in connection with the consummation of the transactions
contemplated by this Agreement, including, without limitation, the Company's
independent public accountants (including the expenses of any comfort letters or
costs associated with the delivery by

                                      -8-
<PAGE>

independent public accountants of a comfort letter or comfort letters). In
addition, the Company shall be responsible for all of its internal expenses
incurred in connection with the consummation of the transactions contemplated by
this Agreement (including, without limitation, all salaries and expenses of its
officers and employees performing legal or accounting duties), the expense of
any annual audit, and the fees and expenses incurred in connection with the
listing of the Registrable Securities on any securities exchange as required
hereunder. The Company shall not be responsible for the payment of any
commissions or other expenses incurred by the Holder in connection with their
sales of Registrable Securities or for the fees of any Special Counsel.

      6. Indemnification

            (a) Indemnification by the Company. The Company shall,
notwithstanding any termination of this Agreement, indemnify and hold harmless
MBN, its permitted assignees, officers, directors, agents, brokers (including
brokers who offer and sell Registrable Securities as principal as a result of a
pledge or any failure to perform under a margin call of Common Stock),
investment advisors and employees, each Person who controls MBN or a permitted
assignee (within the meaning of Section 15 of the Securities Act or Section 20
of the Exchange Act) and the officers, directors, agents and employees of each
such controlling Person, and the respective successors, assigns, estate and
personal representatives of each of the foregoing, to the fullest extent
permitted by applicable law, from and against any and all claims, losses,
damages, liabilities, penalties, judgments, costs (including, without
limitation, costs of investigation) and expenses (including, without limitation,
reasonable attorneys' fees and expenses) (collectively, "Losses"), as incurred,
arising out of or relating to any untrue or alleged untrue statement of a
material fact contained in the Registration Statement, any Prospectus, as
supplemented or amended, if applicable, or arising out of or relating to any
omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in the light of the circumstances under
which they were made) not misleading, except (i) to the extent, but only to the
extent, that such untrue statements or omissions are based solely upon
information regarding the Holder furnished in writing to the Company by the
Holder expressly for use in the Registration Statement, such Prospectus or such
form of Prospectus or in any amendment or supplement thereto, or (ii) as a
result of the failure of the Holder to deliver a Prospectus, as amended or
supplemented, to a purchaser in connection with an offer or sale (provided that
copies of the Prospectus, as amended or supplemented, have been provided to the
Holder by the Company for delivery to such purchaser). The Company shall notify
the Holder promptly of the institution, threat or assertion of any Proceeding of
which the Company is aware in connection with the transactions contemplated by
this Agreement. Such indemnity shall remain in full force and effect regardless
of any investigation made by or on behalf of an Indemnified Party (as defined in
Section 6(c) hereof) and shall survive the transfer of the Registrable
Securities by the Holder.

            (b) Indemnification by MBN. MBN and its permitted assignees shall,
jointly and severally, indemnify and hold harmless the Company, its directors,
officers, agents and employees, each Person who controls the Company (within the
meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act),
and the directors, officers, agents or employees of such controlling Persons,
and the respective successors, assigns, estate and personal representatives of
each of the foregoing, to the fullest extent permitted by applicable law, from
and against any and all Losses, as incurred, arising out of or relating to any
untrue or

                                       -9-
<PAGE>

alleged untrue statement of a material fact contained in the Registration
Statement, any Prospectus, as supplemented or amended, if applicable, or arising
out of or relating to any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein (in
the case of any Prospectus or form of prospectus or supplement thereto, in the
light of the circumstances under which they were made) not misleading, to the
extent, but only to the extent, that (i) such untrue statement or omission is
contained in or omitted from any information so furnished in writing by the
Holder or the Special Counsel to the Company specifically for inclusion in the
Registration Statement or such Prospectus, and (ii) such information was
reasonably relied upon by the Company for use in the Registration Statement,
such Prospectus or such form of prospectus or, to the extent that such
information relates to the Holder or the Holder's proposed method of
distribution of Registrable Securities, was reviewed and expressly approved in
writing by the Holder expressly for use in the Registration Statement, such
Prospectus or such form of Prospectus Supplement. Notwithstanding anything to
the contrary contained herein, the Holder shall be liable under this Section
6(b) for only that amount as does not exceed the net proceeds to the Holder as a
result of the sale of Registrable Securities pursuant to such Registration
Statement.

            (c) Conduct of Indemnification Proceedings. If any Proceeding shall
be brought or asserted against any Person entitled to indemnity pursuant to
Section 6(a) or 6(b) hereunder (an "Indemnified Party"), such Indemnified Party
promptly shall notify the Person from whom indemnity is sought (the
"Indemnifying Party) in writing, and the Indemnifying Party shall assume the
defense thereof, including the employment of counsel reasonably satisfactory to
the Indemnified Party and the payment of all fees and expenses incurred in
connection with defense thereof; provided, that the failure of any Indemnified
Party to give such notice shall not relieve the Indemnifying Party of its
obligations or liabilities pursuant to this Agreement, except (and only) to the
extent that it shall be finally determined by a court of competent jurisdiction
(which determination is not subject to appeal or further review) that such
failure shall have materially and adversely prejudiced the Indemnifying Party.

            An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless: (i) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (ii) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (iii) the
named parties to any such Proceeding (including any impleaded parties) include
both such Indemnified Party and the Indemnifying Party, and such Indemnified
Party shall have been advised by counsel that a conflict of interest is likely
to exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld, conditioned or delayed. No
Indemnifying Party shall, without the prior written consent of the Indemnified
Party, which consent shall not unreasonably be withheld, conditioned or delayed,
effect any settlement of any pending Proceeding in respect of which any
Indemnified Party is a party, unless such settlement includes

                                      -10-
<PAGE>

an unconditional release of such Indemnified Party from all liability on claims
that are the subject matter of such Proceeding.

            All reasonable fees and expenses of the Indemnified Party (including
reasonable fees and expenses to the extent incurred in connection with
investigating or preparing to defend such Proceeding in a manner not
inconsistent with this Section) shall be paid to the Indemnified Party, as
incurred, within ten (10) Business Days of written notice thereof to the
Indemnifying Party (regardless of whether it is ultimately determined that an
Indemnified Party is not entitled to indemnification hereunder; provided, that
the Indemnifying Party may require such Indemnified Party to undertake to
reimburse all such fees and expenses to the extent it is finally judicially
determined that such Indemnified Party is not entitled to indemnification
hereunder or pursuant to applicable law).

            (d) Contribution. If a claim for indemnification under Section 6(a)
or 6(b) is unavailable to an Indemnified Party because of a failure or refusal
of a governmental authority to enforce such indemnification in accordance with
its terms (by reason of public policy or otherwise), then each Indemnifying
Party, in lieu of indemnifying such Indemnified Party, shall contribute to the
amount paid or payable by such Indemnified Party as a result of such Losses, in
such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party and Indemnified Party in connection with the actions,
statements or omissions that resulted in such Losses as well as any other
relevant equitable considerations. The relative fault of such Indemnifying Party
and Indemnified Party shall be determined by reference to, among other things,
whether any action in question, including any untrue or alleged untrue statement
of a material fact or omission or alleged omission of a material fact, has been
taken or made by, or relates to information supplied by, such Indemnifying Party
or Indemnified Party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action, statement or
omission. The amount paid or payable by a party as a result of any Losses shall
be deemed to include, subject to the limitations set forth in Section 6(c), any
reasonable attorneys' or other reasonable fees or expenses incurred by such
party in connection with any Proceeding to the extent such party would have been
indemnified for such fees or expenses if the indemnification provided for under
Section 6(a) or 6(b) was available to such party in accordance with its terms.
Notwithstanding anything to the contrary contained herein, the Holder shall be
liable or required to contribute under this Section 6(d) for only that amount as
does not exceed the net proceeds to the Holder as a result of the sale of
Registrable Securities pursuant to the Registration Statement.

            The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 6(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

            The indemnity and contribution agreements contained in this Section
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

                                      -11-

      7. Rule 144.

            As long as the Holder owns Registrable Securities, the Company
covenants to timely file (or obtain extensions in respect thereof and file
within the applicable grace period) all reports required to be filed by the
Company after the date hereof pursuant to Section 13(a) or 15(d) of the Exchange
Act and to promptly furnish the Holder with true and complete copies of all such
filings. As long as the Holder owns Registrable Securities, if the Company is
not required to file reports pursuant to Section 13(a) or 15(d) of the Exchange
Act, it will prepare and furnish to the Holder and make publicly available in
accordance with Rule 144(c) promulgated under the Securities Act annual and
quarterly financial statements, together with a discussion and analysis of such
financial statements in form and substance substantially similar to those that
would otherwise be required to be included in reports required by Section 13(a)
or 15(d) of the Exchange Act, as well as any other information required thereby,
in the time period that such filings would have been required to have been made
under the Exchange Act. The Company further covenants that it will take such
further action as the Holder may reasonably request, all to the extent required
from time to time to enable the Holder to sell the Common Shares without
registration under the Securities Act within the limitation of the exemptions
provided by Rule 144 promulgated under the Securities Act. Upon the request of
any Holder, the Company shall deliver to such Holder a written certification of
a duly authorized officer as to whether it has complied with such requirements.

      8. Miscellaneous.

            (a) Remedies. In the event of a breach by the Company or by the
Holder of any of their obligations under this Agreement, the Holder or the
Company, as the case may be, in addition to being entitled to exercise all
rights granted by law and under this Agreement, including recovery of damages,
will be entitled to specific performance of its rights under this Agreement. The
Company and the Holder each agree that monetary damages would not provide
adequate compensation for any losses incurred by reason of a breach by it of any
of the provisions of this Agreement and hereby further each agree that, in the
event of any action for specific performance in respect of such breach, it shall
waive the defense that a remedy at law would be adequate.

            (b) No Inconsistent Agreements. Neither the Company nor any of its
Affiliates has as of the date hereof entered into, nor shall the Company or any
of its Affiliates, on or after the date of this Agreement, enter into, any
agreement with respect to its securities that is inconsistent with the rights
granted to the Holder in this Agreement or otherwise conflicts with the
provisions hereof. Without limiting the generality of the foregoing, without the
written consent of the Holder, the Company shall not grant to any Person the
right to request the Company to register any securities of the Company under the
Securities Act if the rights so granted are inconsistent with the rights granted
to the Holder set forth herein, or otherwise prevent the Company with complying
with all of its obligations hereunder.

            (c) Consent to Jurisdiction. The Company and MBN (i) hereby
irrevocably submit to the non-exclusive jurisdiction of the United States
District Court for the Central District of California and the courts of the
State of California located in the City of Los Angeles, California, for the
purposes of any suit, action or proceeding arising out of or relating to this

                                      -12-
<PAGE>

Agreement, and (ii) hereby waive, and agree not to assert in any such suit,
action or proceeding, any claim that it is not personally subject to the
jurisdiction of such court, that the suit, action or proceeding is brought in an
inconvenient forum or that the venue of the suit, action or proceeding is
improper. The Company and MBN consent to process being served in any such suit,
action or proceeding by mailing a copy thereof to such party at the address in
effect for notices to it under this Agreement and agrees that such service shall
constitute good and sufficient service of process and notice thereof. Nothing in
this Section 8(d) shall affect or limit any right to serve process in any other
manner permitted by law.

            (d) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and MBN.

            (e) Notices. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be in writing
and shall be deemed given and effective on the earlier of (i) the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified for notice prior to 5:00 p.m., Pacific
Time, on a Business Day, (ii) the first Business Day after the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile telephone number specified for notice later than 5:00 p.m., Pacific

                              PLAN OF DISTRIBUTION

      We are registering the shares of common stock on behalf of the selling
stockholders. The common stock may be sold in one or more transactions at fixed
prices, at prevailing market prices at the time of sale, at prices related to
the prevailing market prices, at varying prices determined at the time of sale,
or at negotiated prices. These sales may be effected at various times in one or
more of the following transactions, or in other kinds of transactions:

      -     transactions on the NASDAQ Stock Market or on any national
            securities exchange or U.S. inter-dealer system of a registered
            national securities association on which the common stock may be
            listed or quoted at the time of sale;

      -     in the over-the-counter market;

      -     in private transactions and transactions otherwise than on these
            exchanges or systems or in the over-the-counter market;

      -     in connection with short sales of the shares;

      -     by pledge to secure or in payment of debt and other obligations;

      -     through the writing of options, whether the options are listed on an
            options exchange or otherwise;

      -     in connection with the writing of non-traded and exchange-traded
            call options, in hedge transactions and in settlement of other
            transactions in standardized or over-the-counter options; or

      -     through a combination of any of the above transactions.

      The selling stockholders and their successors, including their
transferees, pledgees or donees or their successors, may sell the common stock
directly to purchasers or through underwriters, broker-dealers or agents, who
may receive compensation in the form of discounts, concessions or commissions
from the selling stockholders or the purchasers. These discounts, concessions or
commissions as to any particular underwriter, broker-dealer or agent may be in
excess of those customary in the types of transactions involved.

      The selling stockholders also may engage in short sales against the box,
puts and calls and other transactions in our securities or derivatives of our
securities and may sell or deliver shares in connection with these trades.

      In addition, any securities covered by this prospectus which qualify for
sale pursuant to Rule 144 of the Securities Act may be sold under Rule 144
rather than pursuant to this prospectus.

                                       A-1
<PAGE>

      The selling stockholders may from time to time pledge or grant a security
interest in some or all of the shares of common stock owned by them and, if they
default in the performance of their secured obligations, the pledgees or secured
parties may offer and sell the shares of common stock from time to time under
this prospectus after we have filed an amendment to this prospectus under Rule
424(b)(3) or other applicable provision of the Securities Act amending the list
of selling stockholders to include the pledgee, transferee or other successors
in interest as selling stockholders under this prospectus.

      The selling stockholders also may transfer the shares of common stock in
other circumstances, in which case the transferees, pledgees or other successors
in interest will be the selling beneficial owners for purposes of this
prospectus and may sell the shares of common stock from time to time under this
prospectus after we have filed an amendment to this prospectus under Rule
424(b)(3) or other applicable provision of the Securities Act amending the list
of selling stockholders to include the pledgee, transferee or other successors
in interest as selling stockholders under this prospectus.

      The selling stockholders and any broker-dealers or agents that are
involved in selling the shares of common stock may be deemed to be
"underwriters" within the meaning of the Securities Act in connection with such
sales. In such event, any commissions received by such broker-dealers or agents
and any profit on the resale of the shares of common stock purchased by them may
be deemed to be underwriting commissions or discounts under the Securities Act.

      We entered into a registration rights agreement for the benefit of the
selling stockholders to register the common stock under applicable federal and
state securities laws. The registration rights agreement provides for
cross-indemnification of the selling stockholders and us and our respective
directors, officers and controlling persons against specific liabilities in
connection with the offer and sale of the common stock, including liabilities
under the Securities Act. We will pay substantially all of the expenses incurred
by the selling stockholders incident to the registration of the common stock.

      The selling stockholders have advised us that they have not entered into
any agreements, understandings or arrangements with any underwriters or
broker-dealers regarding the sale of their shares of common stock, nor is there
an underwriter or coordinating broker acting in connection with a proposed sale
of shares of common stock by any selling stockholder. If we are notified by any
selling stockholder that any material arrangement has been entered into with a
broker-dealer for the sale of shares of common stock, if required, we will file
a supplement to this prospectus. If the selling stockholders use this prospectus
for any sale of the shares of common stock, they will be subject to the
prospectus delivery requirements of the Securities Act.

      The anti-manipulation rules of Regulation M under the Securities Exchange
Act may apply to sales of our common stock and activities of the selling
stockholders.

      Re:   CytRx Corporation

Ladies and Gentlemen:

      We are counsel to CytRx Corporation, a Delaware corporation (the
"COMPANY"), and have represented the Company in connection with that certain
Registration Rights Agreement with MBN Consulting, LLC ("MBN") (the
"REGISTRATION RIGHTS AGREEMENT"), dated as of May 10, 2004, pursuant to which
the Company agreed, among other things, to register the Registrable Securities
(as defined in the Registration Rights Agreement and consisting of shares of the
Company's common stock issuable upon exercise of warrants issued by the Company
to MBN) under the Securities Act of 1933, as amended (the "1933 ACT"). In
connection with the Company's obligations under the Registration Rights
Agreement, on _________ __, 2004, the Company filed a Registration Statement on
Form _________ (File No. 333-________) (the "REGISTRATION STATEMENT") with the
Securities and Exchange Commission (the "SEC") relating to the resale of the
Registrable Securities which names MBN as selling stockholder thereunder.

      In connection with the foregoing, we advise you that a member of the SEC's
staff has advised us by telephone that the SEC has entered an order declaring
the Registration Statement effective under the 1933 Act at [ENTER TIME OF
EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after
telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and, accordingly, the
Registrable Securities are available for resale under the 1933 Act in the manner
specified in, and pursuant to the terms of, the Registration Statement.

                                        Very truly yours,

                                        By:
