                    CANCELLATION OF THE CAPITAL STOCK OF GGC

                        AND EXCHANGE WITH RESPECT THERETO

         2.1 Effect on Capital Stock. At the Effective Time, by virtue of the
             -----------------------
Merger, and without any action on the part of CytRx, GGC or Merger Sub or the
shareholders of GGC or Merger Sub thereof:

         (a) subject to the other provisions of Article II, each share of common
stock of GGC issued and outstanding immediately prior to the Effective Time
(other than Dissenting Shares) shall be converted into the right to receive a
number of shares of CytRx Common Stock equal to the quotient of (i) 9,962,881
divided by (ii) the sum of the total number of shares of GGC common stock
outstanding at the Effective Time (including those shares issued between the

outstanding on the date hereof), plus the number of shares of GGC common stock
issuable upon the exercise of any Converting Options (as defined in Section 2.4)

fractional shares will be issued in the Merger. Each fractional share less than
one-half of share shall be rounded down to the nearest whole share and each
fractional share equal to or greater than one-half of a share shall be rounded
up to the nearest whole share. The total number of shares of CytRx Common Stock
issued pursuant to Section 2.1(a) above are collectively referred to herein as,

consideration therefor;

         (c) each share of common stock, par value $.01 per share, of Merger Sub
issued and outstanding immediately prior to the Effective Time shall be
converted into and become one fully paid and nonassessable share of common stock
of the Surviving Corporation; and

         (d) notwithstanding anything in this Agreement to the contrary, to the
extent required by the CCC, CytRx will not make any payment of Merger
Consideration with respect to Shares held by any person (a "Dissenting
                                                            ----------
Stockholder") who elects to demand appraisal of such Dissenting Stockholder's
-----------
Shares and duly and timely complies with all the provisions of the CCC
concerning the right of holders of Shares to require appraisal of their Shares
("Dissenting Shares"), but such Dissenting Stockholders shall have the right to
  -----------------
receive such consideration as may be determined to be due such Dissenting
Stockholders pursuant to the dissenters' rights/shareholder appraisal laws of
the State of California after such Dissenting Stockholder has surrendered his or
her Certificate or Certificates representing Shares for which payment is being
made and has complied with all other requirements of the CCC. If, after the
Effective Time, a Dissenting Stockholder withdraws such Dissenting Stockholder's
demand for appraisal or fails to perfect or otherwise is no longer entitled to
such Dissenting Stockholder's right of appraisal and payment for such holder's
Shares, in any case pursuant to the CCC, such Dissenting Stockholder's Shares
will be deemed to have been converted as of the Effective Time into the right to
receive the applicable portion of the Merger Consideration pursuant to Section
2.1(a) and the Payment Agent shall issue and deliver the applicable portion of
the Merger Consideration to which such Dissenting Stockholder is entitled under
Section 2.1(a) upon surrender by such holder of the Certificate or Certificates
representing the Shares of GGC held by such Dissenting Stockholder immediately
prior to the Effective Time, in accordance with Section 2.2(b). GGC will give
CytRx prompt notice of any demands for appraisal of Dissenting Shares received
by GGC.

2.2      Delivery of Merger Consideration.
         --------------------------------

         (a) Payment Agent. Promptly after the Effective Time, CytRx shall
             -------------
deposit with CytRx's transfer agent or another exchange agent selected by CytRx
(the "Payment Agent"), for the benefit of the holders of the Shares, for payment
      -------------
in accordance with this Article II through the Payment Agent, a number of shares
of CytRx Common Stock equal to the Merger

                                       4

<PAGE>

Consideration, reduced by (i) the Secondary Merger Consideration (as defined
below) and (ii) the number of shares of CytRx Common Stock issuable upon the
exercise of Converting Options and any other GGC Stock Options outstanding at
the Effective Time (the "Initial Merger Consideration"). Five percent (5%) of
the Merger Consideration, or 498,144 shares of CytRx Common Stock (the
"Secondary Merger Consideration") will be held by CytRx (the "Escrow Agent") in
                                                              ------------
escrow in accordance with Section 2.3 and the Escrow Agreement.

         (b) Payment Procedures. As soon as reasonably practicable after the
             ------------------
Effective Time, the Payment Agent shall mail to each holder of record of a
certificate or certificates which at the Effective Time represented Shares (the
"Certificates"), the following documents: (i) a letter of transmittal (which
 ------------
shall specify that delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the Payment
Agent and shall be in such form and have such other provisions as GGC, CytRx and
the Payment Agent may reasonably specify); and (ii) instructions for use in
effecting the surrender of the Certificates in exchange for payment with respect
thereto. Upon surrender of a Certificate for cancellation to the Payment Agent
together with such letter of transmittal, duly executed, the holder of such
Certificate shall be entitled, subject to Section 2.3, to receive in exchange
therefor the Merger Consideration payable with respect to the Shares represented
by such Certificate pursuant to the provisions of this Article II, and the
Certificate so surrendered shall forthwith be cancelled. In the event that a
holder has lost or misplaced a Certificate, or a Certificate has been destroyed
or stolen, an affidavit of loss thereof (together with an appropriate indemnity
and bond and any other document necessary to evidence and effect such bona fide
transfer, if CytRx so requires by notice in writing to the holder of such
Certificate) satisfactory in form and substance to CytRx and the Payment Agent
shall accompany such letter of transmittal in lieu of the applicable
Certificate. In the event of a transfer of ownership of Shares which is not
registered in the transfer records of GGC, payment of the applicable Merger
Consideration may be made to a transferee if the Certificate representing such
Shares is presented to the Payment Agent, accompanied by all documents required
to evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid. Until surrendered as contemplated by this Section
2.2, each Certificate (other than Dissenting Shares to which statutory
dissenters' rights have been perfected as provided in Section 2.1(d)) shall be
deemed at any time after the Effective Time to represent only the right to
receive upon such surrender the Merger Consideration with respect thereto
subject to Sections 2.3 and Article VIII. No interest shall accrue or be paid to
any beneficial owner of Shares or any holder of any Certificate with respect to
the Merger Consideration payable upon the surrender of any Certificate. CytRx
and the Payment Agent shall not be obligated to deliver any Merger Consideration
until a holder of Shares surrenders such holder's Certificate or Certificates of
Shares for exchange in accordance with this Section 2.2(b).

         (c) No Further Ownership Rights in the Shares. The Merger Consideration
             -----------------------------------------
(as may be adjusted by Sections 2.3, 2.5 and Article VIII) paid with respect to
the cancellation of Shares in accordance with the terms hereof shall be deemed
to have been paid in full satisfaction of all rights pertaining to such Shares
and after the Effective Time there shall be no further registration of transfers
on the stock transfer books of the Surviving Corporation of the Shares which
were outstanding immediately prior to the Effective Time. If, after the
Effective Time, Certificates are presented to the Surviving Corporation for any
reason, they shall be cancelled and exchanged as provided in this Article II,
subject to applicable law in the case of Dissenting Shares. No dividend or other
distribution payable to the holders of record of CytRx Common Stock as of any

                                       5

<PAGE>

time subsequent to the Effective Time shall be delivered to the holder of any
Certificate until such holder surrenders such Certificate for exchange as
provided in this Article II.

         (d) No Liability. If any Certificates shall not have been surrendered
             ------------
prior to five (5) years after the Effective Time (or immediately prior to such
earlier date on which the Merger Consideration in respect of such Certificate
would otherwise escheat to or become the property of any Regulatory Authority),
any cash or other property payable in respect of such Certificate shall, to the
extent permitted by applicable law, become the property of the Surviving
Corporation, free and clear of all claims or interest of any person previously
entitled thereto. Notwithstanding the foregoing, none of the Surviving
Corporation, CytRx or the Payment Agent shall be liable to any holder of a
Certificate or the Shares represented thereby for any Merger Consideration
delivered in respect of such Certificate or the Shares represented thereby to a
public official pursuant to any abandoned property, escheat or other similar
law.

         (e) Withholding Rights. CytRx or the Payment Agent shall be entitled to
             ------------------
deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of Certificates or Shares represented thereby such
amounts (if any) as CytRx or the Payment Agent is required to deduct and
withhold with respect to the making of such payment under the Internal Revenue
Code of 1986, as amended (the "Code"), or any provision of state, local or
                               ----
foreign tax Law. To the extent that amounts are so withheld by CytRx or the
Payment Agent, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the Shares in respect of which
such deduction and withholding was made by CytRx or the Payment Agent.

         2.3 Escrow Agreement. At Closing, CytRx, the Escrow Agent and the GGC
             ----------------
Shareholder Representative shall enter into an escrow agreement in the form
attached hereto as Exhibit 2.3 (the "Escrow Agreement"). Promptly after the
                                     ----------------
Effective Time, each GGC Escrowee will be deemed to have received and consented
to the deposit of the Secondary Merger Consideration with the Escrow Agent to be
held in escrow in accordance with the terms of the Escrow Agreement.

         2.4  Stock Options and Warrants with Respect to Shares.
              -------------------------------------------------

         (a) GGC shall take all actions necessary pursuant to the terms and
provisions of any outstanding options or warrants to acquire shares of its
capital stock, or otherwise, to cause the following: (i) all outstanding options
or warrants to acquire shares of GGC capital stock granted by GGC (the "GGC
                                                                        ---
Stock Options") shall be exercisable in full immediately prior to the Effective
-------------
Time and (ii) all GGC Stock Options that are not exercised one day prior to the
Effective Time will terminate and expire as of the Effective Time, except for
those options or warrants granted by GGC to Steven A. Kriegsman, Clifford H.
Pearson, Steve K. Wasserman, David B. Casselman, Leonard J. Comden, Leonard P.
Ruiz, Jr., Elliott J. Cody and Jeffrey L. Davidson (copies of which are attached
hereto as Exhibit 2.4) (the "Converting Options"), which shall be treated as set
                             ------------------
forth in subparagraph (b) below. GGC shall give written notice to the holders of
all GGC Stock Options of the foregoing. All actions required to be taken
pursuant to this Section 2.4 with respect to GGC Stock Options has been, or
prior to the Effective Time will be, taken by GGC.

         (b) At the Effective Time, the Converting Options shall be converted
into and become an option to purchase CytRx Common Stock, and CytRx shall assume
each Converting Option, in accordance with its terms, except that from and after
the Effective Time, (i) each

                                       6

<PAGE>

Converting Option assumed by CytRx hereunder may be exercised solely for shares
of CytRx Common Stock, (ii) the number of shares of CytRx Common Stock subject
to such Converting Option shall be equal to the number of shares of GGC common
stock subject to such Converting Option immediately prior to the Effective Time
multiplied by the Exchange Ratio, and (iii) the per share exercise price under
each such Converting Option shall be adjusted by dividing the per share exercise
price under each such Converting Option by the Exchange Ratio and rounding up to
the nearest cent. CytRx shall not be obligated to issue any fraction of a share
of CytRx Common Stock upon exercise of Converting Options and any fraction of a
share of CytRx Common Stock that otherwise be subject to a Converting Option
shall rounded to the nearest whole share.

         2.5 Accrued GGC Liabilities; Adjustment to Merger Consideration. At
             -----------------------------------------------------------
Closing, GGC shall deliver a certificate (the "Closing Liabilities Certificate")
                                               -------------------------------
signed by the chief executive officer and chief financial officer of GGC,
certifying as to GGC's good faith estimate as to the amount of liabilities of
GGC accrued but unpaid at Closing (other than liabilities for (i) the Audit
Expenses (as defined in Section 5.1(b)) and (ii) the fees, costs and expenses of
Wasserman, Comden, Casselman & Pearson LLP, which will be handled in accordance
with the Letter Agreement). To the extent that such estimate exceeds $5,000, the
number of shares of CytRx Common Stock issuable as Merger Consideration
hereunder at Closing shall be reduced by a number of shares (rounded to the
nearest whole share) that, when multiplied by the Average Closing Price (as
defined in Section 8.5(c)) equals the amount of such accrued but unpaid
liabilities. If the Merger Consideration is adjusted downwards in accordance
with this Section 2.5, the reduced number of shares (instead of 9,962,881) shall
be the number used to determine the Exchange Ratio in Section 2.1(a).

                                   ARTICLE III

                         REPRESENTATIONS AND WARRANTIES

respect to indemnification than are set forth in the articles of incorporation
of GGC, which provisions shall not be amended, repealed or otherwise modified
for a period of six years from the Effective Time in any manner that would
adversely affect the rights thereunder of individuals who at the Effective Time
were directors or officers of GGC. From and after the Effective Time, for a
period of six years, CytRx shall (i) cause the Surviving Corporation to
indemnify the directors and officers of GGC and (ii) indemnify the members of
the CytRx board of directors and the officers of CytRx immediately prior to the

favorable than the provisions with respect to indemnification that are set forth
in the certificate of incorporation of CytRx as of the Effective Time.

favorable of (1) the terms of CytRx's current insurance coverage or (2) the
directors' and officers' liability insurance provided by CytRx after the
Effective Time to directors or officers of CytRx who are not Existing CytRx
Directors and Officers. In addition, CytRx shall take all actions necessary to

of directors' and officers' liability insurance. If at any time prior to the

carrier with respect to its directors' and officers' liability insurance, CytRx
shall purchase tail coverage. Notwithstanding any of the above, prior to the
Effective Time, CytRx may purchase a prepaid extended reporting (or tail) binder
on its existing directors' and officers' liability insurance policy.

         (c) by GGC, upon a material breach of any representation, warranty,
covenant or agreement on the part of CytRx or Merger Sub set forth in this

have become untrue such that the conditions set forth in Section 6.3 would be
incapable of being satisfied by July 31, 2002;

         (d) by either CytRx or GGC, if (i) any Consent of any Regulatory

contemplated hereby shall have been denied by final nonappealable action of such
authority or if any action taken by such authority is not appealed within the
time limit for appeal, or (ii) any injunction or action by any Regulatory
Authority permanently restraining, enjoining or otherwise preventing the

required to be performed at or prior to the Effective Time);

         (f) by either CytRx or GGC, if any approval of the stockholders of
CytRx required for the consummation of the Merger shall not have been obtained
by reason of the failure to obtain the required vote at the CytRx Stockholders'
Meeting or at any adjournment thereof.

         7.2 Effect of Termination. In the event of termination of this
             ---------------------
Agreement and abandonment of the Merger by either GGC or CytRx as provided in

liability or obligation on the part of CytRx, Merger Sub or GGC or their

Confidentiality Agreement, all of which obligations shall survive termination of
this Agreement in accordance with their terms.

                                  ARTICLE VIII

                            SURVIVAL; INDEMNIFICATION

         8.1 Survival of Representations and Warranties; Survival of Fraud
             -------------------------------------------------------------
Claims.
------

         (a) The representations and warranties of the parties hereto contained
herein shall survive the Closing and Effective Time and shall remain in full
force and effect until the first anniversary of the Effective Time. Any right of
indemnification pursuant to this Article VIII with respect to a claimed breach
of (i) a representation or warranty shall expire on the first anniversary of the
Effective Time and (ii) any covenant or agreement shall expire one year after
the date on which performance of such covenant or agreement was required (in
each case, the "Indemnification Expiration Date"), unless in each case on or
                -------------------------------
prior to the Indemnification

Expiration Date an Indemnification Claim (as defined below) has been delivered
to the Party from whom indemnification is sought. Provided that an
Indemnification Claim is timely made, such Indemnification Claim may continue to
be asserted beyond the Indemnification Expiration Date of the representation,
warranty, covenant or agreement to which such Indemnification Claim relates. An
"Indemnification Claim" means a written notice asserting a breach of a
 ---------------------
representation, warranty, covenant, agreement or obligation specified in this
Agreement, which shall reasonably set forth, in light of the information then
known to the party giving such notice, a reasonably detailed description of and
estimate (but only if then reasonable to make) of the amount involved in such
breach.

         (b) Any right of a Party to bring a claim against another Party hereto
based on fraud in connection with this Agreement or the transactions
contemplated hereby must be brought on or before the second annual anniversary
of the Effective Time, or such claim shall be deemed to have expired and be
forever waived by the Party alleging such fraud.

         8.2  Indemnification.
              ---------------

         (a) After the Effective Time and until the applicable Indemnification
Expiration Date, CytRx or the CytRx Representative, on behalf of CytRx, may
deliver an Indemnification Claim to the GGC Shareholder Representative on behalf
of GGC and the GGC Escrowees for all Damages asserted against, imposed upon or
incurred by CytRx by reason of or resulting from (i) a breach of any
representation, warranty, covenant or agreement of GGC contained in this
Agreement or any certificate delivered pursuant hereto or (ii) the termination
by GGC of the GGC Stock Options as contemplated by Section 2.4.

         (b) After the Effective Time and until the applicable Indemnification
Expiration Date, the GGC Shareholder Representative on behalf of GGC and the GGC
Escrowees may deliver an Indemnification Claim to CytRx and the CytRx
Representative on behalf of CytRx for all Damages asserted against, imposed upon
or incurred by GGC by reason of or resulting from a breach of any
representation, warranty, covenant or agreement of CytRx contained in this
Agreement or any certificate delivered pursuant hereto.

         8.3 Third Party Claims. Indemnification Claims made in respect of any
             ------------------
claims made or asserted by a third party ("Third Party Claims") shall be
                                           ------------------
governed in accordance with the following procedures:

         (a) The Party making the Indemnification Claim through its respective
Representative (the "Indemnified Party") shall give the GGC Shareholder
                     -----------------
Representative or CytRx Representative, as the case may be, (the "Indemnifying
                                                                  ------------
Party") written notice as promptly as reasonably practicable after the written
-----
assertion of any Third Party Claim describing in reasonable detail the nature of
the Third Party Claim to the extent then known to the Indemnified Party (a
"Third Party Claim Notice").
 ------------------------

         (b) Upon receipt of any Third Party Claim Notice from the Indemnified
Party, (i) the CytRx Representative, on behalf of CytRx, or (ii) the GGC
Shareholder Representative, on behalf of GGC and the GGC Escrowees, as the case
may be, may (unless the anticipated

                                       40

<PAGE>

Damages exceed the maximum amount of indemnification under Section 8.4)
undertake the defense, compromise and settlement thereof by representatives of
its own choosing reasonably acceptable to the Indemnified Party, the expenses,
fees and costs of which shall be added to the Damages amount included in the
Recoverable Amount pursuant to Section 8.5 of (i) GGC if the CytRx
Representative undertakes such defense or (ii) CytRx if the GGC Shareholder
Representative undertakes such defense. The assumption of the defense,
compromise and settlement of any such Third Party Claim by a Representative will
not be an acknowledgment by an Indemnifying Party of the obligation to indemnify
the Indemnified Party with respect to such claim. If, however, a Representative
fails or refuses to undertake the defense of such Third Party Claim within ten
business days after notice of such Third Party Claim has been given to the
Representative, the Indemnified Party will have the right to undertake the
defense, compromise and settlement of such claim with counsel of its own
choosing. If an Indemnifying Party undertakes the defense of a Third Party Claim
and if in the reasonable opinion of counsel to the Indemnified Party there may
exist defenses available to the Indemnified Party that are different from or in
addition to those available to the Indemnifying Party or if the Indemnified
Party otherwise believes that its interests would be adversely affected by the
Indemnifying Party assuming sole control of the defense of such Third Party
Claim, the Indemnified Party shall be entitled to retain separate counsel to
participate in the defense of such Third Party Claim at its sole expense.

         (c) No settlement of a Third Party Claim involving the asserted
liability of the Indemnifying Party under this Section shall be made without the
prior written consent by the respective Representative on behalf of such the
Indemnifying Party. If the Indemnifying Party assumes the defense of a Third
Party Claim, (i) no compromise or settlement thereof may be effected by the
Indemnifying Party without the Indemnified Party's prior written consent unless
(A) there is no finding or admission of any violation of law by or on behalf of
the Indemnified Party, (B) the sole relief provided is monetary damages that are
paid in full by the Indemnifying Party and (C) the compromise or settlement
includes, as an unconditional term thereof, the giving by the claimant or the
plaintiff to the Indemnified Party of a release, in form and substance
reasonably satisfactory to the Indemnified Party, from all liability in respect
of such Third Party Claim, and (ii) the Indemnified Party shall have no
liability with respect to any compromise or settlement thereof affected without
its consent.

         (d) Each Party will provide the other Party with access to all records,
documents and personnel of such Party to the extent reasonably related to any
Third Party Claim.

         8.4  Limitation of Liability.
              -----------------------

         (a) No Indemnification Claim may be made by any Party unless the
aggregate amount of Damages indemnified against hereunder exceeds $25,000 in the
aggregate, after which the Party may make an Indemnification Claim for the
entire amount of Damages (including the first $25,000).

         (b) In no event may the CytRx Representative on behalf of CytRx recover
Damages under this Article VIII in excess of the Secondary Merger Consideration.

                                       41

<PAGE>

         (c) In no event may the GGC Shareholder Representative on behalf of GGC
and the GGC Escrowees recover Damages under this Article VIII in excess of the
number of shares of CytRx Common Stock comprising the Secondary Merger
Consideration at the Effective Time.

         8.5  Payment of Indemnification Claims.
              ---------------------------------

         (a) All Damages recovered under this Article VIII shall be recovered in
shares of CytRx Common Stock as set forth below. Although Indemnification Claims
may be delivered at any time prior to the applicable Indemnification Expiration
Date (subject to Section 8.4 above), no recovery of Damages shall be made by
either party hereto until the first business day after the first anniversary
date of the Effective Time (the "Recovery Date"). Upon the Recovery Date, or if
any Indemnification Claim is still pending on the Recovery Date, on the first
business day after final resolution of all pending Indemnification Claim(s), the
parties shall add the aggregate amount of Damages recoverable by each party
pursuant to Indemnification Claims properly made and resolved under this Article
VIII (each a "Recoverable Amount"). The Party with the greater Recoverable
Amount shall be entitled to recover an amount equal to the excess of such
Party's Recoverable Amount minus the other Party's Recoverable Amount (the
"Final Recoverable Amount").

         (b) If CytRx has a greater Recoverable Amount on the Recovery Date,
CytRx shall, in accordance with the Escrow Agreement, cancel a number of shares
of CytRx Common Stock included in the Secondary Merger Consideration that when
multiplied by the Average Closing Price equals the Final Recoverable Amount. For
purposes of this Section 8.5(b), all fractional shares shall be rounded up to
the nearest whole share. The remaining shares of CytRx Common Stock included in
the Secondary Merger Consideration held in escrow, if any, shall be distributed
to the GGC Escrowees in accordance with the Escrow Agreement.

         (c) If the GGC Escrowees have a greater Recoverable Amount on the
Recovery Date, CytRx shall issue a number of additional shares of CytRx Common
Stock to the GGC Escrowees equal to the quotient of (A) the Final Recoverable
Amount, divided by (B) the Average Closing Price (as defined below) of the CytRx
Common Stock (the "Additional Merger Consideration"). No fractional shares will
                   -------------------------------
be issued as Additional Merger Consideration. All such fractional shares shall
be rounded up to the nearest whole share. Each GGC Escrowee will receive a
percentage of the Additional Merger Consideration, which percentage shall be
calculated by dividing (i) the number of shares of CytRx Common Stock included
in the Initial Merger Consideration that were received by such GGC Escrowee by
(ii) the total number of shares of CytRx Common Stock included in the Initial
Merger Consideration that were received by all GGC Escrowees. No fractional
shares will be issued to the GGC Escrowees. Each fractional share less than
one-half of share shall be rounded down to the nearest whole share and each
fractional share equal to or greater than one-half of a share shall be rounded
up to the nearest whole share. In no event will the shares of CytRx Common Stock
issued to the GGC Escrowees after such rounding exceed the number of shares
calculated above as the Additional Merger Consideration. The "Average Closing
                                                              ---------------
Price" means the average of the daily last sale prices for the shares of the
-----

         8.6 Exclusive Remedy. After the Effective Time, except for Claims
             ----------------
relating to actual fraud and except for equitable remedies, the remedies
provided in this Article VIII constitute the sole and exclusive remedies between
the parties for Damages or any other Claims arising under this Agreement,
including Claims based upon the inaccuracy, untruth, incompleteness or breach of
any representation or warranty contained in this Agreement or based upon the
failure to perform any covenant, agreement or undertaking contained in this
Agreement.

         8.7  Representatives.
              ---------------

         (a) CytRx and the CytRx Representative are entitled to rely upon all
actions taken and documents provided by the GGC Shareholder Representative as
the actions of GGC and the GGC Escrowees and neither CytRx nor the CytRx
Representative shall have any liability or obligation to GGC or the GGC
Escrowees other than as provided in this Article VIII.

         (b) GGC and the GGC Shareholder Representative are entitled to rely
upon all actions taken and documents provided by the CytRx Representative as the
actions of CytRx and neither GGC nor the GGC Shareholder Representative shall
have any liability or obligation to CytRx other than as provided in this Article
VIII.

         8.8 Dispute Resolution. Except for Claims (i) relating to temporary,
             ------------------
preliminary or emergency injunctive or other equitable relief pending resolution
of an arbitration proceeding hereunder and (ii) enforcing the provisions of this
Section 8.8 or an arbitration award, if the Parties are unable to resolve any
disputes hereunder, such dispute shall be submitted to final and binding
arbitration before JAMS, or its successor, pursuant to the United States
Arbitration Act, 9 U.S.C. Sec. 1 et seq. Either Party may commence the
arbitration process called for in this Agreement by filing a written demand for
arbitration with JAMS, with a copy to the other Parties. The arbitration will be
conducted in accordance with the provisions of JAMS' Streamlined Arbitration
Rules and Procedures in effect at the time of filing of the demand for
arbitration. The Parties will cooperate with JAMS and with one another in
selecting an arbitrator from JAMS' panel of neutrals, and in scheduling the
arbitration proceedings. The Parties covenant that they will participate in the
arbitration in good faith, and that they will share equally in its costs. The
provisions of this Section 8.8 may be enforced by any court of competent
jurisdiction, and the Party seeking enforcement shall be entitled to an award of
all Damages to be paid by the Party against whom enforcement is ordered.
