the transactions contemplated by this Agreement. Purchaser shall examine the
Closing Financial Statements and have the right to review all prior audit and
accounting working papers with respect to the Business and the preparation of
the Closing Financial Statements. If Purchaser disagrees with the proposed
Closing Financial Statements, Purchaser and Seller shall endeavor to reach
agreement on the disputed matters within the 30-day period following delivery
of the proposed Closing Financial Statements to Purchaser. If the parties are
unable to reach agreement, the disputed matters shall be promptly submitted to
an arbitrator selected by Seller and Purchaser in accordance with the rules of
the American Arbitration Association (the "ARBITRATOR"), the decision of which
shall be rendered within sixty (60) days and 



                                      -18-

shall be final and binding upon Purchaser and Seller. Purchaser and Seller shall
bear equally the costs and expenses of the Arbitrator.

         (b) The Purchase Price shall be increased by an amount which reflects
the positive difference, if any, of (i) Seller's Net Working Capital, as
reflected on the Closing Financial Statements and (ii) $1,000,000, or decreased
by an amount which reflects the negative difference, if any, of (i) Seller's Net
Working Capital, as reflected on the Closing Financial Statements and (ii)
$1,000,000, (the "WORKING CAPITAL ADJUSTMENT"). For purposes of this Agreement,
"NET WORKING CAPITAL" means the difference, positive or negative, between the
Assets and the Assumed Liabilities as of the Closing Date. Within five (5)
business days after the Working Capital Adjustment is determined on the basis of
the Closing Financial Statements, each party shall make any additional payments
by wire transfer of immediately available federal funds necessary to place all
parties in the respective positions they would have occupied had the amount of
the Working Capital Adjustment (as finally determined) been known as of the
Closing Date, provided that if the Working Capital Adjustment is positive and
exceeds the amount of cash and cash equivalents reflected on the Closing
Financial Statements, then the amount of the wire transfer to be made by
Purchaser shall be limited to the amount of such cash and cash equivalents and
the principal amount of the Promissory Note shall be increased for any excess
amount.

         Section 2.9.  Promissory Note. On the Closing Date, Purchaser shall 
deliver to Seller the Promissory Note which shall be unsecured and shall bear
interest as set forth in the Promissory Note. The unpaid principal amount of the
Promissory Note, and any accrued and unpaid interest thereon, shall be paid in
full upon the earlier of (a) December 15, 1998, or (b) the closing date on which
Purchaser obtains substitute financing for the Promissory Note.

         Section 2.10. Contingent Payments.

respective meanings for all purposes hereof:

exclusive right as an agent for Optimum Quality Grains to receive commissions up
to and including December 31, 2008 with respect to the sale and distribution to
the confined fed cattle industry in the United States of Optimum Quality Grains
products known as High Oil Corn. Notwithstanding other provisions of this

                  (ix) "Senior Claim" shall mean all liabilities, obligations
and indebtedness of any and every kind and nature, of Purchaser to a lender,
other than a Permitted Transferee, whether heretofore, now or hereafter owing,
arising, due or payable, and howsoever evidenced, created, incurred, acquired or
owing, provided that such liabilities, obligations and indebtedness arise out of
the financing of the transactions contemplated by this Agreement, refinancings
or renewals of such indebtedness or indebtedness relating to the provision of
working capital to Purchaser insofar as the aggregate amount of such
indebtedness does not exceed $6,500,000, except such amount may be increased to
reflect, on a dollar for dollar basis, any upward adjustments made to the
principal amount of the Note pursuant to Section 2.8(b). Without limiting the
foregoing, Senior Claim shall include all commitment, facility and other fees
and expenses (including attorneys' fees and disbursements), payable to a lender

as Seller shall have been paid an aggregate of $2,000,000 pursuant to this
Section 2.10(b)(i).

                       (c)  Notwithstanding the provisions of this Section
2.10(b)(i), Purchaser shall have no obligation to enter into the DuPont
Agreement or continue such agreement in effect; provided, however, that if the
DuPont Agreement is executed by Purchaser after the Closing Date and terminated
for any reason prior to payment in full of the aggregate amount under Section
2.10(b)(i)(b) and Purchaser enters into a subsequent agreement for the
distribution of High Oil Corn products, then the payment obligations under
Section 2.10(b)(i)(b) shall remain in effect and apply to such subsequent

                        (b)  Purchaser shall pay to Seller 10% of the Adjusted  
Net Revenues derived by Purchaser from the sale or distribution of Ivermectin
Products, including any new or supplemental Ivermectin Products (the "IVERMECTIN
BUSINESS") during the period beginning after the Closing Date and terminating on
the earlier of (i) December 31, 2005 or (ii) such time as Seller shall have been
paid an aggregate of $2,000,000 pursuant to this Section 2.10(b)(ii).

                  (iii) Liquidity Payment. (a) Upon the closing of any one of
the following events (collectively, the "LIQUIDITY EVENTS"), Purchaser shall pay

of Purchaser or any successor entity.

                  (b)   The obligations of Purchaser under this Section 2.10(b)
(iii) shall terminate upon the earlier of (a) Purchaser's payment of an
aggregate of $1,500,000 to Seller or (b) December 31, 2008.



                                      -22-
<PAGE>   24


                  (c)  Notwithstanding the provisions of Section 2.10(b)(iii)(a)
and (b), any sale or exchange to any Permitted Transferee described in Sections
2.10(b)(iii)(a)(1), (2) or (3) shall not terminate Purchaser's obligation to
make the Liquidity Payment and, upon the subsequent consummation by such
Permitted Transferee of any sale, exchange or transfer described in Sections
2.10(b)(iii)(a)(1), (2) or (3) to any Person other than a Permitted Transferee,
Purchaser shall make, or cause the successor entity of Purchaser to make, the
Liquidity Payment to Seller. Such successor entity's assumption of Purchaser's
liability to make the Liquidity Payment shall be a condition to such transfer.

                  (d)  Notwithstanding the provisions of Section 2.10(b)(iii)(a)
and (b), the occurrence of any Permitted Change in Control shall not terminate
Purchaser's obligation to make the Liquidity Payment to Seller. Upon the
occurrence of a subsequent Change in Control by the Permitted Transferees,
Purchaser shall make, or cause the successor entity of Purchaser to make, the
Liquidity Payment to Seller.

                  (e)  Sections 2.10(b)(iii)(a)(1), (2) and (3) shall apply with
the same force and effect to any single transaction or to any series of related
or integrated transactions which have the same result.

           (c)    General Provisions. The following provisions shall be 
applicable to the payment of the Contingent Payments as set forth in this
Section 2.10:

                  (i)  Delivery of Contingent Payments. Purchaser shall deliver
to the Seller each of the Contingent Payments as required by this Section 2.10,
without interest except as provided in Section 2.10(c)(ii), within the following
time periods (each, a "CONTINGENT PAYMENT PERIOD"): (a) within thirty (30) days
of the execution of the DuPont Agreement in the case of the High Oil Corn
Payments; (b) within thirty (30) days of the Purchaser's receipt of final FDA
approval of the right to market any Ivermectin Product in the case of the
Ivermectin Payments and (c) upon the closing of any one of the Liquidity Events
(collectively, the execution of the DuPont Agreement, the receipt of final FDA
approval and the closing of any of the Liquidity Events shall be referred to as
the "TRIGGERING EVENTS"). Any portion of a Contingent Payment which is
calculated as a percentage of Purchaser's Adjusted Net Revenues shall be paid by
Purchaser to Seller no later than forty-five (45) days after the end of the
calendar quarter in which such Adjusted Net Revenues were derived (a "REVENUE
PAYMENT DATE").

                  (ii) Interest and Expenses. Any Contingent Payment which is
payable by Purchaser in accordance with this Section 2.10 and which is not paid
in full by Purchaser in accordance with the time periods set forth in paragraph
(i) 



                                      -23-
<PAGE>   25


above shall bear interest on the unpaid balance at the rate of 1% per month
calculated from the date of the Triggering Event, or, in any case where the
Contingent Payment is calculated as a percentage of Adjusted Net Revenues, from
the Revenue Payment Date. In addition, if all or a portion of a Contingent
Payment remains unpaid for three business days after the receipt by Purchaser of
Seller's written notification that such payment is due and that either the
Contingent Payment Period has expired or the Revenue Payment Date has passed, as
the case may be, Purchaser will reimburse Seller for reasonable costs incurred
in connection with the collection of the Contingent Payment from Purchaser
(including reasonable attorneys' fees and expenses).

                  (iii) Notification of Triggering Events. Purchaser shall
notify Seller of the occurrence of any Triggering Event within ten (10) days
after its occurrence and shall promptly furnish to Seller written confirmations
of the occurrence of such Triggering Event, including, but not limited to,
copies of any approval letters of the FDA.

                  (iv)  Accounting. (a) For purposes of calculating the
Contingent Payments, Purchaser shall furnish to Seller quarterly statements of
Adjusted Net Revenues (the "REVENUE STATEMENTS"), certified by the Chief
Financial Officer of Purchaser, for each fiscal quarter no more than thirty (30)
days after the end of Purchaser's fiscal quarter. Such Revenue Statements must
be accurately prepared from the books and records of Purchaser in accordance
with GAAP. The Revenue Statements shall include such supporting documentation as
Seller shall reasonably request in writing.

                  (b)   In the event that, in accordance with the subordination
terms of Section 2.10(c)(vii) hereof, amounts otherwise payable at the Revenue
Payment Date must be withheld, the Purchaser agrees to set aside such amounts
which are due and owing in a separate, interest-bearing account (the nature of
which is to be reasonably satisfactory to Seller), and to maintain such separate
account until payment hereunder, including any interest earned on the account,
may be made to Seller in accordance with the terms hereof. Notwithstanding
anything to the contrary set forth in the preceding sentence, it is expressly
understood and agreed that any payments to Seller from such interest-bearing
account shall be subject to the subordination terms of Section 2.10(c)(vii)
hereof and that payments due to the holder of the Senior Claim may be satisfied
in whole or in part by payment to the holder of the Senior Claim of funds set
aside in such interest-bearing account, and the failure by Purchaser to maintain
such separate account as a result of such payment to the holder of the Senior
Claim shall not thereafter constitute a violation of this Agreement.



                                      -24-
<PAGE>   26



                  (c) Purchaser shall keep and maintain detailed and accurate
books and records with regard to the Contingent Payments and the calculation
thereof. Upon reasonable notice from Seller and during normal business hours,
and no more than once during any twelve (12) month period, Seller or its
representatives (who shall be bound in confidence not to disclose information
except to inform Seller of discrepancies), at Seller's expense, shall be
entitled to review and audit such books and records for the purpose of verifying
the accuracy of any prior Revenue Statement and Purchaser's compliance with
Section 2.10 of this Agreement.

                  (d) If a deficiency in any Contingent Payment is discovered by
Seller or its representatives, Seller shall notify the Purchaser in writing of
the amount of such deficiency and the basis for such calculation (the
"DEFICIENCY NOTICE"). Upon receipt of such notice the Purchaser shall either (i)
promptly pay Seller the amount of such deficiency or (ii) exercise his right to
object to the Deficiency Notice as set forth in Section 2.10(c)(iv)(e).

                  (e) Purchaser shall have thirty (30) days to object to
Seller's Deficiency Notice upon receipt thereof. Within five (5) days of any
such objection, representatives of Seller and Purchaser shall meet to resolve
their differences. If no resolution is reached within sixty (60) days from the
date of the Deficiency Notice, the dispute shall be submitted to arbitration in
accordance with Section 2.10(c)(v) of this Agreement.

                  (f) If a deficiency of 10% or more is discovered by either (i)
Seller's examination, if Purchaser agrees to pay the amounts set forth in the
Deficiency Notice as provided for in Section 2.10(c)(iv)(d), or (ii) the
arbitrator selected pursuant to Section 2.10(c)(iv)(e), and such amount exceeds
$5,000, Purchaser shall (i) reimburse Seller for the cost and expense of such
examination and (ii) pay Seller interest on such deficiency at the rate and in
the manner provided for late Contingent Payments by Section 2.10(c)(ii) of this
Agreement.

                  (v) Dispute Resolution. (a) Unless otherwise provided in this
Section 2.10, each of Purchaser and Seller agrees that any dispute or
controversy arising out of or in connection with this Section 2.10 or any
alleged breach hereof shall be settled by arbitration in New York, New York
pursuant to the rules of the American Arbitration Association ("AAA"). The
arbitration will be governed by the Commercial Arbitration Rules of the AAA and
the arbitrators shall apply the substantive law of the State of New York
(without regard to its conflicts of laws or choice of law principles) to the
determination of the dispute. If Purchaser and Seller cannot jointly select a
single arbitrator to determine the matter, one arbitrator shall be chosen by
each of Purchaser and Seller (or, if a party fails to make a choice, by the
American Arbitration Association on behalf of such party) 


                                      -25-
<PAGE>   27


and the two arbitrators so chosen will select a third. The decision of the
single arbitrator jointly selected by Purchaser and Seller, or, if three
arbitrators are selected, the decision of any two of them, will be final and
binding upon the parties and the judgment of a court of competent jurisdiction
may be entered thereon. Fees of the arbitrators and costs of arbitration shall
be borne by Purchaser and Seller in such manner as shall be determined by the
arbitrator or arbitrators.

                       (b) Purchaser and Seller agree that the Supreme Court of 
the State of New York, County of New York shall be the sole and exclusive forum
in connection with any action to compel arbitration pursuant to this paragraph
or to enforce, modify or vacate any arbitration award. The parties further agree
that such court may exercise personal jurisdiction over them in connection with
such actions or proceedings and that they waive any objections or defenses they
each may have concerning the exercise of such personal jurisdiction or venue in
such court.

                       (c) In connection with any arbitration or legal 
proceeding pursuant to this paragraph, the parties agree that papers in
connection therewith may be served upon the parties in accordance with Section
11.5.

                  (vi)  Place and Form of Payment. The Contingent Payments shall
be made in United States dollars by wire transfer in accordance with wire
transfer instructions provided by Seller to Purchaser at least three business
days prior to either the Revenue Payment Date or the expiration of the
Contingent Payment Period, as the case may be.

                  (vii) Subordination. (a) Seller and CytRx and any of their
successors or assigns agree (expressly for the benefit of any future holder of a
Senior Claim) that the obligation of Purchaser to make any Contingent Payment is
subordinate, to the extent and in the manner hereinafter set forth, in right of
payment to the prior payment of any Senior Claim. Purchaser will not make any
Contingent Payment at any time during which (i) full payment of amounts then due
under the Senior Claim, whether for principal, premium, interest or otherwise,
has not been made or provided for, (ii) there shall have occurred and be
continuing a default with respect to the Senior Claim, which has not been
waived, in each case pursuant to the terms of the Senior Claim or (iii) payment
of a Contingent Payment would render Purchaser unable to make payments on the
Senior Claim as they become due.

                       (b) Upon any distribution of the assets of Purchaser in 
connection with any dissolution, winding up, liquidation or reorganization of
Purchaser (whether in bankruptcy, insolvency or receivership proceedings) or
upon 



                                      -26-
<PAGE>   28


any assignment for the benefit of creditors or any other marshalling of the
assets and liabilities of Purchaser or otherwise:

                                    (i)     the holder of the Senior Claim 
shall be entitled to receive payment in full of the Senior Claim (including
interest accruing from and after the commencement of any such proceedings at the
rate specified in the Senior Claim except to the extent prohibited by mandatory
provisions of law) before Seller shall be entitled to receive any payment
hereunder;

                                    (ii)    any payment or distribution of 
assets of Purchaser, of any kind or character, whether in cash, property or
securities, to which Seller would be entitled but for the provisions of this
paragraph shall be paid or delivered directly to the holder of the Senior Claim
for application in payment thereof; and

                                    (iii)   in the event that, notwithstanding 
the foregoing, any such payment or distribution of assets shall be received by
Seller before the Senior Claim shall have been paid in full, such payment or
distribution shall be held in trust for the benefit of and shall be paid over or
delivered to the holder of the Senior Claim, for application in payment thereof
in accordance with the provisions of subsection (ii) of this Section
2.10(d)(vii)(b).

                           (c)      If any payment is made to the holder of the 
Senior Claim which, but for the provisions of Section 2.10(d)(vii) would have
been made to Seller, when the indebtedness to the holder of the Senior Claim is
paid in accordance with Section 2.10(d)(vii), Seller will be subrogated to the
claim of the holder of the Senior Claim against Purchaser to the extent of the
amount of the Senior Claim which was paid out of sums which otherwise would have
been payable to Seller, and no such payment or distribution for the account of
the holder of the Senior Claim shall, for the purposes of Section 2.10(d)(vii),
be deemed to be a payment or distribution by Purchaser on account of the Senior
Claim.

                           (d)      Nothing contained in Section 2.10(d)(vii) 
is intended to or shall impair, as between Purchaser and Seller, the
obligation of Purchaser to pay to Seller the Contingent Payments as and when
the same shall become due and payable in accordance with the terms of this
Agreement, or is intended to or shall affect the relative rights of Seller and
creditors of Purchaser other than the holder of the Senior Claim.

                  (viii)   Right of Set-Off. (a) In the event that, during the
Contingent Payment Period or at the Revenue Payment Date, as the case may be,
there shall be outstanding any Indemnity Claim in favor of Purchaser pursuant to
Article V or Section 8.2 of this Agreement, then Purchaser shall have the right,


                                      -27-
<PAGE>   29


upon prior written notice to Seller and subject to the terms of this Agreement,
to set-off against the amount which would otherwise be payable to Seller
hereunder an amount equal to such unpaid Indemnity Claim. If Seller disputes any
amount determined by Purchaser to be owing, then the disputed amount otherwise
payable to Seller hereunder shall be deposited by Purchaser with an escrow agent
selected by Purchaser and Seller pending the resolution of such dispute. This
right of set-off shall be in addition to any other remedy which Purchaser may
have pursuant to Article V of this Agreement.

         (b) If it is determined, either by mutual agreement of Purchaser and
Seller or by the arbitrator selected to resolve the dispute as set forth in
Section 2.10(c)(viii)(a), that Purchaser improperly set-off amounts which were
otherwise payable to Seller, the amount which was improperly withheld by
Purchaser shall accrue interest at the rate of 12% as of the date such amount
was otherwise payable to Seller in accordance with the terms of this Agreement
until the full amount of the payment and all interest accrued thereon have been
paid to the Seller.

                  (ix) Transfers by Purchaser. (a) Purchaser shall not transfer
or sell the High Oil Corn business or the Ivermectin Business (each, a "TRANSFER
OF THE BUSINESS") unless the purchaser or transferee thereof expressly assumes
Purchaser's obligations to make the High Oil Corn Payments or the Ivermectin
Payments, respectively, to Seller.

                       (b)  Except as set forth in Sections 2.10(b)(iii) and  
2.10(c)(ix)(a), nothing contained herein shall prohibit or restrict in any way
the right of Purchaser to make or to cause to be made a sale or disposition of
all or any portion of the Business or to terminate or discontinue or cause to be
terminated or discontinued all or any portion of the Business (each, a
"DISPOSITION") and no Contingent Payment shall become due or owing as a result
of any such Disposition except as expressly provided in this Section 2.10.

                       (c)  Purchaser shall notify Seller of any proposed

the defense of any such claim or any litigation resulting therefrom, provided
that counsel for the Indemnifying Party, who shall conduct the defense of such

Indemnified Party may participate in such defense at such party's expense, and
provided further that the failure of any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations

any such claim or litigation, shall not, except with the consent of the
Indemnified Party, consent to entry of any judgment or entry into any settlement

the part of the Indemnifying Party under this Article V or Sections 8.2 or 10.3
is determined (which in the case of payment to third persons shall be the
earlier of (a) the date of such payments or (b) the date that a court of
competent jurisdiction shall enter a final judgment, order or decree (after
exhaustion of appeal rights) establishing such liability) (such loss or amount
being hereinafter referred to as the "INDEMNITY CLAIM"), the Indemnifying Party
shall forthwith, upon prompt notice from the Indemnified Party, pay to the
Indemnified Party the amount of the Indemnity Claim. If such amount is not paid
forthwith, then the Indemnified Party may, at its option, take legal action
against the Indemnifying Party for reimbursement in the amount of its Indemnity
Claim. For purposes hereof, the Indemnity Claim shall include the amounts so
paid, or determined to be owing, by the Indemnified Party together with costs
and reasonable attorneys' fees and interest on the foregoing items at the prime
rate of Citibank, N.A. in effect as of such time from the date the Indemnity
Claim is due from the Indemnifying Party to the Indemnified Party as hereinabove
provided, until the Indemnity Claim shall be paid.

contemplated hereby, the performance by Seller and CytRx of their obligations
hereunder and thereunder, and the transactions contemplated hereby and thereby
have been duly and validly authorized by all necessary corporate action on the
part of Seller and CytRx. This Agreement is a legal, valid and binding
obligation of Seller and CytRx, enforceable against each of them in accordance

generally or by general principles of equity, regardless of whether such
enforceability is considered in equity or at law).

         Section 6.4. No Conflict. Except as set forth in Schedule 6.4, neither 
the execution and delivery of this Agreement or any of the other documents
contemplated hereby by Seller or CytRx nor the consummation of the transactions

by Seller as of the date hereof and which are described in Schedule 6.16 and
with respect to medical, dental, disability and prescription benefits and life
insurance which are substantially the same as Ivy provides to its comparable
employees. Such 



                                      -50-
<PAGE>   52


employees shall also receive options to purchase equity interests in the
Purchaser on terms which are substantially the same as the terms provided to
such employees by Seller as of the date hereof.

         Section 8.5. Use of Name. From and after the Closing Date, Seller will 
sign such consents and take such other action as Purchaser shall reasonably
request in order to give Purchaser the exclusive right to use the name "VetLife"
and all variants thereof.

         Section 8.6. Change in Name. On or prior to the Closing Date, Seller 
shall deliver to Purchaser (i) a certified copy of a Certificate of Amendment to
the Certificate of Incorporation of the Seller and such other appropriate
certifications, pursuant to which Seller shall have changed its name to another
name bearing no similarity to the name "Vetlife" and (ii) written evidence of
Seller's abandonment of any similar assumed name(s).

         Section 8.7. Supply of Products. From and after the Closing Date, in 
the event Seller is required to supply products related to the Business to its
former customers pursuant to any obligation which arose under an Assigned
Agreement prior to the Closing Date, Purchaser shall use its reasonable efforts
to supply the requisite products to the Seller for the sole purpose of
satisfying such pre-closing obligation to Seller's former customer. Purchaser
shall provide such products to Seller in accordance with the terms and
conditions then in effect under the New Distribution Agreement and Seller shall
pay Purchaser the price paid by Purchaser for such products under the New
Distribution Agreement.

         Section 8.8. Cooperation with Counterclaims, Affirmative Defenses and
Other Rights. In the event Seller has a valid counterclaim, affirmative defense
or other right against any of its former customers arising under any of the
Assigned Agreements that constitute Retained Assets, Purchaser shall cooperate
with Seller to assert such counterclaim, affirmative defense or other right;
provided that such right, whether in the same or independent actions, is
asserted only in response to a claim for relief asserted against Seller or
against Purchaser if Purchaser has rights related to such claim that it may
assert against Seller, and provided further, that such right is not reflected as
an account receivable on the Closing Financial Statements. Seller shall bear all
of Seller's and Purchaser's out-of-pocket costs and expenses (including
reasonable attorney's fees) relating to the assertion of such counterclaim or
affirmative defense.

         Section 8.9. JAccess to Tax Information. (a) Seller agrees to provide 
to Purchaser access to copies of returns and reports, pertaining to all U.S.
federal, state, local and foreign Taxes with respect to the Business filed by
Seller or any 


                                      -51-
<PAGE>   53


predecessor, assignor or other entity, the liabilities of which Seller has
assumed or succeeded to, or for which they are, or may be, otherwise
responsible, for 1997 and subsequent taxable years to the date hereof. Purchaser
and Seller hereby agree that any information obtained pursuant to this Section
8.9 shall be held in strict confidence and that all information so obtained
shall be subject to the terms and conditions of the Confidentiality Agreement in
the form of Exhibit J hereto. Seller shall not be required to provide
information with regard to returns or reports or portions thereof relating to
any Taxes which are not exclusively related to the Business.

                     IX. CERTAIN ACTIONS AFTER THE CLOSING.

         Section 9.1. Purchaser to Act as Agent for Seller. This Agreement 
shall not constitute an agreement to assign any contract right included among
the Assets if any attempted assignment of the same without the consent of the
other party thereto would constitute a breach thereof or in any way adversely
affect the rights of Seller thereunder. If such consent is not obtained or if
any attempted assignment would be ineffective or would adversely affect
Seller's rights thereunder so that Purchaser would not in fact receive all such
rights, then Purchaser may, after the Closing, in its discretion, act as the
agent for Seller in order to obtain for Purchaser the benefits thereunder.
Except as otherwise expressly provided herein, nothing herein shall be deemed
to make Purchaser the agent of Seller in respect of the Retained Assets.

         Section 9.2. Purchaser Appointed Attorney for Seller. Subject to 
Section 5.6, Seller, effective as of the Closing Date, hereby constitutes and
appoints Purchaser, its successors and assigns, the true and lawful attorney of
Seller, in the name of either Purchaser or Seller (as Purchaser shall determine
in its sole discretion) but for the benefit of Purchaser: (a) to institute and
prosecute, upon giving notice to Seller, all proceedings which Purchaser may
deem proper in order to collect, assert or enforce any claim, right or title of
any kind in or to the Assets as provided for in this Agreement; (b) to defend or
compromise, upon giving notice to Seller, any and all actions, suits or
proceedings in respect of any of the Assets, and to do all such acts and things
in relation thereto as Purchaser shall deem advisable; and (c) to take all
action which Purchaser, its successors or assigns may reasonably deem proper in
order to provide for Purchaser, its successors or assigns, the benefits under
any of the Assets where any required consent of another party to the sale or
assignment thereof to Purchaser pursuant to this Agreement shall not have been
obtained. Seller acknowledges that the foregoing powers are coupled with an
interest and shall be irrevocable. Except as otherwise expressly provided
herein, Purchaser shall be entitled to retain for its own account any amounts
collected 



                                      -52-
<PAGE>   54


pursuant to the foregoing powers, including any amounts payable as interest in
respect thereof. Purchaser agrees to act in good faith in seeking to collect,
assert or enforce any claim against any third party in accordance with this
Section 9.2.

         Section 9.3. Subrogation of Purchaser. In the event Purchaser shall 
become liable for or suffer any damage with respect to any matter which was
covered by insurance maintained by Seller on or prior to the Closing Date,
Seller and CytRx agree that Purchaser shall be and hereby is, to the extent
permitted under such policies and to the extent consistent with Article VI
hereof, subrogated to any rights of Seller and CytRx under such insurance
coverage, and Seller and CytRx agree to promptly remit to Purchaser any
insurance proceeds which it may receive on account of any such liability or
damage.

         Section 9.4. Payment of Liabilities. Following the Closing Date, each 
of Purchaser and Seller agree to discharge in accordance with their terms the
Assumed Liabilities and the Excluded Liabilities, respectively.

                             X. CERTAIN TAX MATTERS.

         Section 10.1. Tax Returns Through Closing. Seller shall have prepared 
and filed on a timely basis all reports and returns of Taxes relating to the
Business with respect to all periods through and including the Closing Date and
paid or cause to be paid when due all Taxes relating to the Business for such
periods, including any interest, additions to Tax or penalties thereon together
with interest on such additions to Tax or penalties other than sales, use or
transfer taxes relating to the sale of the Assets which shall be the
responsibility of Purchaser.

         Section 10.2. Refunds. Seller shall be entitled to receive any Tax 
refund to which Seller may be entitled in respect of any period prior to,
through and including the Closing Date.

         Section 10.3. Sales, Use and Transfer Taxes. Purchaser shall pay all 
federal, state and local sales, use and other transfer taxes, if any, due as a
result of the purchase, sale or transfer of the Assets in accordance herewith
whether imposed by law on Seller or Purchaser and Purchaser shall indemnify,
reimburse and hold harmless Seller in respect of the liability for payment of or
failure to pay any such taxes or the filing of or failure to file any reports
required in connection therewith.

         Section 10.4.  Subsequent Liability. If, subsequent to the Closing 
Date, any liability for Taxes relating to the Business is asserted against
Purchaser with respect to any period prior to the Closing Date other than the
sales, use or transfer 



                                      -53-
<PAGE>   55


taxes referred to in Sections 10.1 and 10.3, Seller shall, subject to Sections
5.1, 5.5, 5.6 and 5.7 indemnify and hold Purchaser harmless from and against,
the full amount of such Tax liability, including any interest, additions to Tax
and penalties thereon, together with interest on such additions to Tax or
penalties (as well as reasonable attorneys' or other fees and disbursements of
Purchaser incurred in determination thereof or in connection therewith). Seller
shall, at its sole expense and in its reasonable discretion, either settle any
Tax claim that may be the subject of indemnification under this Section 10.4 at
such time and on such terms as it shall deem appropriate or assume the entire
defense thereof, provided, however, that Seller shall in no event take any
position in such settlement or defense that subjects Purchaser to any civil
fraud or any civil or criminal penalty. Notwithstanding the foregoing, Seller
shall not consent, without the prior written consent of Purchaser, which prior
written consent shall not be unreasonably withheld, to any change in the
treatment of any item which would, in any manner whatsoever, affect the Tax
liability of Purchaser for a period subsequent to the Closing Date.

         Section 10.5. Allocation of Purchase Price. The Purchase Price shall 
be allocated in its entirety among the Assets in accordance with Schedule 10.5
hereto. CytRx, Seller and Purchaser shall file all information and tax returns
(and any amendments thereto) in a manner consistent with this Section 10.5. If,
contrary to the intent of the parties hereto as expressed in this Section 10.5,
any taxing authority makes or proposes an allocation different from that
contained in this Section 10.5, CytRx, Seller and Purchaser shall cooperate
with each other in good faith to contest such taxing authority's allocation (or
proposed allocation), provided, however, that after consultation with the party
adversely affected by such allocation (or proposed allocation), another party
hereto may file such protective claims or returns as may reasonably be required
to protect its interests.

                               XI. MISCELLANEOUS.

         Section 11.1. Expenses. Except as otherwise provided in this 
Agreement, each party to this Agreement shall pay its own costs and expenses
(including all legal and accounting fees incurred by it) relating to this
Agreement, the negotiations leading up to this Agreement and the transactions
contemplated by this Agreement.

         Section 11.2. Amendment. This Agreement shall not be amended or 
modified except by a writing duly executed by Seller and Purchaser.

         Section 11.3. Entire Agreement. This Agreement, including the Exhibits 
and Schedules hereto and the other instruments, agreements and documents
delivered 


                                      -54-

         Section 11.4. Headings. The headings contained in this Agreement are 
intended solely for convenience and shall not affect the rights of the parties

         Section 11.5. Notices. All notices, requests, demands and other

                  FOR VALUE RECEIVED, the undersigned, VetLife L.L.C., a
Delaware limited liability company (hereinafter referred to as the "Debtor,"
which term shall include any successor in interest to all or substantially all
of the Debtor's business or assets), promises to pay to the order of VetLife,
Inc., a Delaware corporation (hereinafter referred to as the "Holder"), at the
offices of the Holder located at 154 Technology Parkway, Norcross, Georgia
30092, or at such other place as the Holder may designate in writing to the
Debtor, in lawful money of the United States of America, and in immediately
available funds, the principal sum of FOUR MILLION DOLLARS ($4,000,000.00)
together with interest on the principal balance from time to time outstanding
hereunder (computed on the basis of a 360-day year for the actual number of days

twelve percent (12%) in simple interest terms.

                  This Note is a duly authorized note of the Debtor, designated
as its 12% Unsecured Promissory Note (the "Note") issued pursuant to the
Acquisition Agreement, dated as of April 17, 1998, by and among the Debtor, the
Holder and CytRx Corporation ("CytRx"), the parent company of the Holder (the
"Acquisition Agreement"). This Note is subject and entitled to certain terms,
conditions, covenants and agreements contained in the Acquisition Agreement. All
capitalized terms used herein and not otherwise defined herein shall have the
respective meanings ascribed to them in the Acquisition Agreement. Reference to
the Acquisition Agreement, and to the other documents delivered in connection
with such Agreement, shall in no way impair the absolute and unconditional
obligation of the Debtor to pay both principal and interest hereon as provided
herein. The obligation of Debtor to pay both principal and interest hereon as
provided herein is in addition to and separate from any obligation of Debtor to
make the Contingent Payments described in the Acquisition Agreement. The

provisions of Section 2.8(b) of the Acquisition Agreement.

financing for this Note (the "Maturity Date"). Except as provided above, accrued
interest shall be due and payable monthly on the 15th day of each month
commencing May 15, 1998, until the principal amount of this Note shall be paid
in full. Interest hereunder shall accrue on a daily basis.

                  Interest shall accrue on any amount past due hereunder after
any applicable grace periods for payment as provided in Section 8 hereof at a

                  All payments received hereunder shall be applied as follows:
(a) first, to the payment of all costs and reasonable expenses of collection, as
the same may be due and payable in accordance with Section 10 hereof; (b)
second, to the payment of interest due hereunder; and (c) third, to the payment
of principal due hereunder.

                  The Debtor may prepay this Note, in whole or in part, at any
time and from time to time, without penalty or premium; provided, that, any such
payment shall be accompanied by payment of all accrued and unpaid interest.

                  2. Usury. In no event shall the amount of interest due or
payable under this Note exceed the maximum rate of interest allowed by
applicable law and, in the event any such payment is inadvertently paid by the
Debtor or inadvertently received by the Holder, then such excess sum shall be
credited as a payment of principal, unless the Debtor shall notify the Holder in
writing that the Debtor elects to have such excess sum returned to it forthwith.
It is the express intent of the parties hereto that the Debtor not pay and the
Holder not receive, directly or indirectly, in any manner whatsoever, interest
in excess of that which may be lawfully paid by the Debtor under applicable law.

                  THE DEBTOR, AND THE HOLDER BY ACCEPTING THIS NOTE, EACH AGREE
AND STIPULATE THAT THE ONLY CHARGE IMPOSED UPON THE DEBTOR FOR THE USE OF MONEY
IN CONNECTION WITH THIS NOTE IS AND SHALL BE THE INTEREST DESCRIBED HEREIN, AND
FURTHER AGREE AND STIPULATE THAT ALL OTHER CHARGES IMPOSED BY THE HOLDER ON THE
DEBTOR IN CONNECTION WITH THIS NOTE, INCLUDING WITHOUT LIMITATION, ALL DEFAULT
CHARGES, ATTORNEYS' FEES AND COLLECTION COSTS, IF ANY, ARE CHARGES MADE TO
COMPENSATE THE HOLDER FOR COSTS OR LOSSES PERFORMED OR INCURRED, AND TO BE
PERFORMED OR INCURRED, BY THE HOLDER IN CONNECTION WITH THIS NOTE AND SHALL
UNDER NO CIRCUMSTANCES BE DEEMED TO BE CHARGES FOR THE USE OF MONEY. ALL CHARGES
OTHER THAN CHARGES FOR THE USE OF MONEY SHALL BE FULLY EARNED AND NONREFUNDABLE
WHEN DUE.

                  3. Subordination. (a) Debtor hereby covenants and agrees that
it will not incur any senior indebtedness (as hereinafter defined), except as
otherwise set forth in this Section 3. Senior indebtedness shall mean all
indebtedness of the Debtor created, 


<PAGE>   62


incurred, assumed or guaranteed by Debtor for money borrowed which is secured by
or which by its terms expressly provides that such debt is senior or superior in
right of payment to this Note.

                     (b) Notwithstanding the foregoing, Debtor and Holder hereby
agree that Debtor may become indebted to any bank, financial institution or
other lender, other than a Permitted Transferee, for an aggregate principal
amount not to exceed $2,500,000 plus the amount of any indebtedness to any
lender other than a Permitted Transferee relating to capitalized leases or
purchase money indebtedness incurred in connection with the purchase of tangible
property by Debtor (the "Senior Indebtedness"). In the event any Senior
Indebtedness is assigned or transferred to any Permitted Transferee, such
indebtedness shall no longer constitute Senior Indebtedness for the purposes
hereof.

                     (c) Holder hereby agrees that the Senior Indebtedness may
be secured by all or a portion of the assets of Debtor, including the Assets
acquired pursuant to the Acquisition Agreement (the "Permitted Liens").

                     (d) Holder hereby agrees that the obligation of Debtor to
make any payment hereunder is irrevocably subordinate in right of payment to the
prior payment of the Senior Indebtedness. The Debtor will not make any payment
hereunder at any time during which (i) full payment of amounts then due under
the Senior Indebtedness, whether for principal, premium, interest or otherwise,
has not been made or provided for, (ii) there shall have occurred and be
continuing a default with respect to the Senior Indebtedness, which has not been
waived, in each case pursuant to the terms of the Senior Indebtedness or (iii)
payment hereunder would render the Debtor unable to make payments on the Senior
Indebtedness as they become due.

                     (e) Upon any distribution of the assets of the Debtor in
connection with any dissolution, winding up, liquidation or reorganization of
the Debtor (whether in bankruptcy, insolvency or receivership proceedings) or
upon any assignment for the benefit of creditors or any other marshalling of the
assets and liabilities of the Debtor or otherwise:

                         (i)  the holder of the Senior Indebtedness shall be
                  entitled to receive payment in full in cash or cash
                  equivalents (or to have such payment duly provided for in a
                  manner reasonably satisfactory to the holder of the Senior
                  Indebtedness) of all amounts due or to become due on or in
                  respect of all Senior Indebtedness, before any payment or
                  distribution, whether in cash, property or securities, is made
                  on account of or applied on this Note;

                         (ii) any payment or distribution of assets of the
                  Debtor, of any kind or character, whether in cash, property or
                  securities, to which Holder would be entitled but for the


<PAGE>   63


                  provisions of this Section 3 shall be paid or delivered by any
                  debtor, custodian, liquidating trustee, agent or other person
                  making such payment or distribution directly to the holder of
                  the Senior Indebtedness for application in payment thereof;

                         (iii) Holder hereby irrevocably authorizes and empowers
                  the holder of the Senior Indebtedness or its representative to
                  collect and receive Holder's share of all such payments and
                  distributions and to give a receipt therefor, and, if Holder
                  fails to file a claim at least thirty (30) calendar days prior
                  to the date established by rule of law or order of court for
                  such a filing, to file and prove (but not to vote or otherwise
                  control) such claims therefor;

                         (iv)  Holder shall execute and deliver to the holder of
                  the Senior Indebtedness or its representative all such further
                  instruments confirming the above authorization and all such
                  powers of attorney, proofs of claim, assignments of claim and
                  other instruments, and shall take all such other action, as
                  may be reasonably requested by the holder of the Senior
                  Indebtedness or such representative, to enforce such claims
                  and to carry out the purposes of this Section 3; and

                         (v)   in the event that, notwithstanding the foregoing,
                  any such payment or distribution of assets shall be received
                  by Holder before the Senior Indebtedness shall have been paid
                  in full, such payment or distribution shall be held in trust
                  for the benefit of and shall be paid over or delivered to the
                  holder of the Senior Indebtedness, for application in payment
                  thereof in accordance with the provisions of this Section 3.

                     (f) If any payment is made to the holder of the Senior
Indebtedness which, but for the provisions of this Section 3, would have been
made to Holder, when the indebtedness to the holder of the Senior Indebtedness
is paid in full, Holder will be subrogated to the claim of the holder of the
Senior Indebtedness against the Debtor to the extent of the amount of the Senior
Indebtedness which was paid out of sums which otherwise would have been payable
to Holder, and no such payment or distribution for the account of the holder of
the Senior Indebtedness shall, for the purposes of this Section 3, be deemed to
be a payment or distribution by the Debtor on account of the Senior
Indebtedness.

                     (g) Nothing contained in this Section 3 or elsewhere in
this Note is intended to or shall impair, as between the Debtor and Holder, the
obligation of the Debtor to pay to Holder all or a portion of the principal and
interest of this Note as and when the same shall become due and payable in
accordance with the terms hereof, or is intended to 


<PAGE>   64


or shall affect the relative rights of Holder and creditors of the Debtor other
than the holder of the Senior Indebtedness.

                  4. Representations and Warranties. In order to induce the
Holder to accept this Note, the Debtor represents and warrants to the Holder as
follows:

                     (a) Organization; Power; Qualification. The Debtor is a
limited liability company, duly organized, validly existing and in good standing
under the laws of its jurisdiction of incorporation, has the power and authority
to own its properties and to carry on its business as now being and hereafter
proposed to be conducted and is duly qualified and authorized to do business in
each jurisdiction in which the character of its properties or the nature of its
business requires such qualification or authorization.

                     (b) Authorization. The Debtor has the right and power, and
has taken all necessary action to authorize it, to execute, deliver and perform
this Note in accordance with its terms. This Note and the instruments,
agreements and other documents to which the Debtor is a party and which evidence
or relate in any way to the obligations hereunder have been executed and
delivered by the authorized officers of the Debtor and each is a legal, valid
and binding obligation of the Debtor enforceable against the Debtor in
accordance with its terms.

                     (c) Compliance with Laws, etc. The execution, delivery and
performance of this Note by the Debtor in accordance with its terms do not and
will not, by the passage of time, the giving of notice or otherwise (i) conflict
with, result in a breach of or constitute a default under any indenture,
instrument or other material agreement to which the Debtor is a party or by
which it or any of its properties may be bound or (ii) result in, or require the
creation or imposition of, any Lien (as defined herein) material in amount upon
or with respect to any property in which the Debtor now or may hereafter have
rights.

                     (d) Liens. None of the properties or assets of the Debtor
are, as of the date hereof, subject to any Lien, except (i) the Permitted Liens
and (ii) the security interests (the "Security Interests") granted to Holder
pursuant to Section 2.10(c)(x) of the Acquisition Agreement. No financing
statement under the Uniform Commercial Code of any jurisdiction which names the
Debtor as debtor or covers any of the properties or assets of the Debtor, or any
other notice filed in the public records indicating the existence of a Lien
thereon, other than in connection with a Permitted Lien or the Security
Interests, has been filed and is still effective in any jurisdiction, and the
Debtor has not signed any such financing statement or notice or any security
agreement authorizing any person or entity to file any such financing statement
or notice.

                         "Lien", as applied to the property or assets of the 
Debtor, means any security interest, lien, encumbrance, mortgage, deed to secure
debt, deed of trust, pledge, charge, conditional sale or other title retention
agreement, or other encumbrance of any kind covering any property or assets of
the Debtor, or upon the income or profits therefrom or any agreement to convey
any of the foregoing or any other 


<PAGE>   65


agreement or interest covering the property or assets of the Debtor which is
intended to provide collateral security for the obligation of the Debtor.

                  5. Affirmative Covenants. So long as any of the obligations
under this Note remain unpaid or unperformed, the Debtor shall:

                     (a) Preservation of Existence and Similar Matters. Preserve
and maintain its existence, rights, franchises, licenses and privileges in the
jurisdiction of its formation and qualify and remain qualified and authorized to
do business in each jurisdiction in which the failure to be so authorized and
qualified would have a material adverse effect on the Debtor's business.

                     (b) Maintenance of Assets and Property. (i) Protect,
maintain and preserve all its material assets and properties.

                     (c) Capital. Debtor shall have initial capital received in
exchange for member interests of $2,000,000.

                     (d) Payment of Taxes and Claims. Pay or discharge when due:
(i) all material taxes, assessments and governmental charges or levies imposed
upon it or upon its income or profits or upon any properties belonging to it,
and (ii) all lawful claims which are material in amount of materialmen,
mechanics, carriers, warehousemen and landlords for labor, materials, supplies
and rentals which, if unpaid, might become a Lien on any properties of the
Debtor; except that this Section 5(d) shall not require the payment or discharge
of any such tax, assessment, charge, levy or claim which is being contested in
good faith by appropriate proceedings which operate to suspend the collection
thereof and for which adequate reserves have been established on the appropriate
books.

                     (e) Reports. Furnish to the Holder copies of all management
reports, financial statements, reports of Debtor's independent public
accountants and other reports, if any, which the Debtor has provided to the
holder of any indebtedness for money borrowed by the Debtor at the time the
Debtor provides such reports to such holder.

                     (f) Notice of an Event of Default. Furnish to the Holder as
soon as reasonably practical and in any event within (i) three (3) days after
the occurrence of an Event of Default (as hereinafter defined) under Sections
8(i), (ii), (iii), (iv), (v), (ix) or (x) or any event that, with the passage of
time or the giving of notice or both, would constitute an Event of Default under
such sections, or (ii) ten (10) days after the occurrence of an Event of Default
under Sections 8(vi), (vii), (viii) or (xi) or any event that, with the passage
of time or the giving of notice or both, would constitute an Event of Default
under such sections, written notice setting forth in detail the nature of such
event and the action which Debtor proposes to take with respect thereto.

                     (g) Related Transactions. Cause the terms and conditions of
all material transactions, contracts and agreements entered into between the
Debtor and any Permitted Transferee, if any, to be fair and reasonable on terms
fully disclosed to Holder 


<PAGE>   66


and no less favorable than the terms and conditions which would be obtained in
an "arms-length" transaction with a party that is not a Permitted Transferee.
For purposes of this Section 5(g), "material" shall refer to any transaction,
contract and agreement entered into between Debtor and any Permitted Transferee,
the total value of which exceeds $10,000. The provisions of this Section 5(g)
shall not apply to the Master Distribution Agreement (as hereinafter defined)
and any advances made by the members of Debtor pursuant to Section 6(a), the
terms of which have been reviewed and approved in writing by Holder.

                  6. Negative Covenants. So long as any portion of the
obligations under this Note remain unpaid or unperformed, the Debtor shall not:

                     (a) Indebtedness for Borrowed Money. Create, assume, or
otherwise become or remain obligated in respect of, or permit or suffer to exist
or to be created, assumed or incurred or to be outstanding any indebtedness for
money borrowed, except the indebtedness represented by this Note, and except for
the Senior Indebtedness. Notwithstanding the foregoing, the members of the
Debtor may make advances to the Debtor so long as (i) Debtor's capital consists
of at least $2,000,000 in equity at the time the advance is made and (ii) such
advances (a) will rank pari passu with this Note; provided, however, that such
advances may be repaid in whole or in part as long as no Event of Default (as
hereinafter defined) has occurred and is continuing, and (b) together with the
Senior Indebtedness, do not exceed the aggregate amount permitted as Senior
Indebtedness.

                     (b) Liens. Create, assume, incur or permit or suffer to
exist or to be created, assumed or incurred, any Lien upon any of its properties
or assets of any character whether now owned or hereafter acquired, except the
Permitted Liens and the Security Interests.

                     (c) Restricted Distributions and Purchases. Except as
permitted by Section 6(a), declare or make (i) any distribution, direct or
indirect, of any earnings or profits to its members in excess of the amounts
required by any members to pay federal, state and local estimated income taxes
with respect to each member's share of the estimated 1998 earnings of the Debtor
computed at the highest combined marginal effective federal, state and local
income tax rate prescribed for an individual resident of New York City with
taxable income of more than $250,000 per annum applicable to the character of
the net tangible income allocable to the member; (ii) any redemption,
conversion, exchange, retirement, sinking fund or similar payment, purchase or
other acquisition for value, direct or indirect, of any equity interest in
Debtor now or hereafter outstanding; and (iii) any payment or prepayment of
principal of, premium, if any, or interest on, redemption, conversion, exchange,
purchase, retirement, defeasance, sinking fund or similar payment with respect
to, any indebtedness, except this Note and any Senior Indebtedness.

                     (d) Modifications to Contracts. Permit that certain
Agreement dated as of April 17, 1998 (the "Master Distribution Agreement") by
and between Ivy Laboratories, Inc., a Delaware corporation ("Ivy"), and the
Debtor, which is attached hereto 


<PAGE>   67


as Exhibit A, to be materially amended or modified in any way that has an
adverse effect on the ability of the Debtor to satisfy its obligations under
this Note, or to be canceled or terminated prior to the expiration of its stated
term.

                       (e) Merger, Consolidation and Sale of Assets. (i) Merge 
or consolidate with any other person or entity, (ii) liquidate, wind-up or
dissolve itself (or suffer any liquidation or dissolution) or (iii) sell, lease
or transfer or otherwise dispose of all or a substantial portion of its assets
to any person or entity; provided, however, that the Debtor may merge with and
into its parent corporation, Ivy Holdings, Inc. or its affiliate, Ivy.

                       (f) No Impairment. By amendment of its Articles of
Organization or Operating Agreement or through any reorganization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities, or any
other voluntary action, intentionally avoid or seek to avoid the observance or
performance of any of the terms to be observed or performed hereunder by the
Debtor, but will at all times in good faith assist in the carrying out of all
the provisions of this Note and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the Holder of this
Note against impairment.

                  7.   Payments of Note - Place and Manner.

                       (a) Place. All payments of principal and interest 
hereunder shall be made in immediately available funds, no later than 10:00
A.M., New York City time, to the Holder of the Note at the offices of the Holder
located at 154 Technology Parkway, Norcross, Georgia 30092, or at such other
place as the Holder may designate in writing to the Debtor.

                       (b) Business Days. Notwithstanding anything to the 
contrary contained herein, if any amount of principal or interest is due
hereunder on a day which is not a business day, the due date thereof shall be
extended to the immediately succeeding business day and interest thereon shall
accrue during the period of such extension at the rate provided therefor in this
Note.

                       (c) Replacement of Note. Upon receipt of evidence
satisfactory to the Debtor of the loss, theft, destruction or mutilation of this
Note and, in the case of any such mutilation, upon surrender and cancellation of
the Note, the Debtor will issue a new Note of like tenor (and, in the case of
any new Note, dated the date to which interest has been paid), in lieu of such
lost, stolen, destroyed or mutilated Note.

                  8.   Default and Remedies. Subject to the terms and conditions
of Section 3 above, if any of the following events (an "Event of Default") shall
occur and be continuing for any reason whatsoever (and whether such occurrence
shall be voluntary or involuntary or come about or be effected by operation of
law or otherwise):

                  (i)  the Debtor defaults in the due and punctual payment of 
                  the principal of this Note when and as the same shall become 
                  due and payable;


<PAGE>   68


                  (ii)  the Debtor defaults in the due and punctual payment of
                  any interest on this Note when the same shall become due and
                  payable and such default shall continue for a period of three
                  (3) business days;

                  (iii) the Debtor defaults in the payment of principal of or
                  interest on any other obligation for money borrowed beyond any
                  period of grace provided with respect thereto, or the Debtor
                  fails to perform or observe any other agreement, term or
                  condition contained in any agreement under which any such
                  obligation is created (or if any other event thereunder or
                  under any such agreement shall occur and be continuing) and
                  the effect of such failure or other event is to cause, or to
                  permit the holder or holders of such obligation (or a trustee
                  on behalf of such holder or holders) to cause, such obligation
                  to become due prior to any stated maturity, which in the case
                  of obligations to Persons other than Permitted Transferees
                  must be in the principal amount of not less than $50,000;

                  (iv)  the Debtor makes an assignment for the benefit of, or
                  enters into a composition with, creditors;

                  (v)   any decree or order for relief in respect of Debtor is
                  entered under any bankruptcy, reorganization, compromise,
                  arrangement, insolvency, readjustment of debt, dissolution or
                  liquidation or similar law whether now or hereafter in effect
                  (herein called the "Bankruptcy Law") of any jurisdiction;

                  (vi)  any petition in bankruptcy shall be filed by or against
                  Debtor or any proceedings in bankruptcy, or under any law or
                  statute of any jurisdiction relating to the relief of debtors,
                  being commenced for the relief or readjust-ment of any
                  indebtedness of Debtor, either through reorganization,
                  composition, extension or otherwise and, if filed against
                  Debtor, such petition or proceeding shall remain unstayed or
                  undismissed for a period of thirty (30) days; provided,
                  however, that, if the filing of such petition or proceeding
                  shall constitute a default under the terms of any agreement
                  relating to any indebtedness for money borrowed by the Debtor
                  (collectively, the "Other Agreements"), the time period
                  referred to in this Section 8(vi) shall be decreased to
                  reflect the opportunity to cure, if any, relating to such
                  petition or proceeding provided to the Debtor in such Other
                  Agreement;

                  (vii) any order, judgment or decree is entered in any
                  proceedings against Debtor decreeing the dissolution of Debtor
                  and such order, judgment or decree remains unstayed and in
                  effect for more than thirty (30) days; provided, however,
                  that, if the entering of such order, judgment or decree shall
                  constitute a default under the terms of any Other Agreement,
                  the time period set forth in this Section 8(vii) shall be
                  decreased to reflect the opportunity to cure, if any, relating
                  to such order, judgment or decree provided to the Debtor in
                  such Other Agreement;


<PAGE>   69


                  (viii) a final judgment in an amount in excess of $50,000 or
                  any final order granting equitable relief, is rendered against
                  Debtor and such judgment or order will have a Material Adverse
                  Effect on the financial condition of the Debtor, and, within
                  thirty (30) days after entry thereof, such judgment or order
                  is not discharged or execution thereof stayed pending appeal,
                  or within thirty (30) days after expiration of any such stay,
                  such judgment or order is not discharged; provided, however,
                  that, if the entering of such judgment or order shall
                  constitute a default under the terms of any Other Agreement,
                  the time periods set forth in this Section 8(viii) shall be
                  decreased to reflect the opportunity to cure, if any, relating
                  to such order, judgment or decree provided to the Debtor in
                  such Other Agreement;

                  (ix)   the Debtor defaults in the due and punctual payment of
                  any Contingent Payment when the same shall become due and
                  payable in accordance with the terms of the Acquisition
                  Agreement;

                  (x)    the Debtor defaults in the due and punctual payment of 
                  any payment relating to any Indemnity Claim when the same
                  shall become due and payable in accordance with the terms of
                  the Acquisition Agreement; or

                  (xi)   the Debtor breaches any obligation not specified in
                  clauses (i) through (x) above which arises under this Note and
                  such breach shall continue for a period of thirty (30) days
                  after the Debtor has received notice of such breach from the
                  Holder:

then (a) if such event is an Event of Default specified in clause (i), (ii),
(iii), (viii), (ix), (x) or (xi) of this paragraph 8, the Holder may, by written
notice to the Debtor, declare the unpaid principal amount of this Note, together
with accrued interest thereon, immediately due and payable, without presentment,
demand, protest or notice of any kind, all of which are hereby waived by the
Debtor, and (b) if such event is an Event of Default specified in clause (iv),
(v), (vi) or (vii) of this paragraph 8, the Note shall automatically become
immediately due and payable together with interest accrued thereon without
presentment, demand, protest or notice of any kind, all of which are hereby
waived by the Debtor.

                  9.     No Right of Set-Off. Debtor shall not under any
circumstances set off any amounts due Debtor by Holder or any other person
against any amounts due Holder hereunder. Any set-off shall be deemed an Event
of Default under Section 8(i) of this Note. Holder acknowledges that Debtor may
have to make payments to the holder of any Senior Indebtedness in accordance
with Section 3 hereof.

                  10.    Miscellaneous.

         The Debtor shall pay all reasonable expenses incurred by the Holder in
the collection of any amounts past due hereunder, including, without limitation,
the reasonable 


<PAGE>   70


fees and disbursements of counsel to the Holder if the amounts past due
hereunder are collected by or through an attorney-at-law.

         All representations and warranties made by the Debtor under this Note
shall be materially true and correct until this Note is paid in full.

         Time is of the essence of this Note.

protests and all other notices whatever.

                  (a) Successors and Assigns. This Note, and the obligations and
rights hereunder, shall be binding upon and inure to the benefit of the Debtor,
the Holder of this Note, and their respective heirs, successors and assigns.

Note or, directly or indirectly, any of their rights or obligations hereunder
without the prior written consent of the other party; provided, however, that
the Holder (i) shall assign this Note and its rights and obligations hereunder
to CytRx upon either (x) the liquidation of the Holder or (y) the sale,
assignment or transfer by CytRx of a controlling interest in the Holder and (ii)
may assign this Note and its rights and obligations hereunder to CytRx at any
time upon three (3) days' prior written notice to the Debtor. Prior to any
assignment to CytRx pursuant to this Section 10(a), CytRx shall agree not to
assign, pledge or otherwise transfer this Note or, directly or indirectly, any
of its rights or obligations hereunder without the prior written consent of the
Holder.

particular instance and either retroactively or prospectively), upon written
consent of the Debtor and the Holder of this Note.

                  (c) Delays. No course of dealing between the Debtor and the
Holder or any failure or delay on the part of the Holder in exercising any
rights or remedies of the Holder and no single or partial exercise of any rights
or remedies hereunder, or under the Acquisition Agreement, shall operate as a
waiver or preclude the exercise of any other rights or remedies hereunder.

                  (d) Currency. All payments shall be made in such coin or
currency of the United States of America as at the time of payment shall be
legal tender therein for the payment of public and private debts.

                                                                       EXHIBIT E

                            NON-COMPETITION AGREEMENT

         (the "Acquisition Agreement"), pursuant to which Buyer is acquiring

                  WHEREAS, to induce Buyer to enter into and consummate the
         transactions contemplated by the Acquisition Agreement, Sellers have
         agreed to enter into this Agreement in favor of Buyer on the terms and
         conditions described below;

                  NOW THEREFORE, in consideration of the Cash Portion of the
         Purchase Price, the Promissory Note and 


<PAGE>   73


         Buyer's obligations to make the Contingent Payments, the receipt and
         sufficiency of which Sellers hereby acknowledge, the parties hereto
         agree as follows:

                  1.  Non-Competition. Vetlife and CytRx each on its own behalf 
                  and on behalf of all their respective Affiliates
                  (collectively, the "Restricted Entities"), jointly and
                  severally, agree that:

                      1.1  During the Restricted Period (as hereinafter
         defined), the Restricted Entities each will not, without Buyer's prior
         written consent, by itself or in conjunction with any other person,
         firm, corporation or other entity, either directly or indirectly:

                      (a)  engage in or have any interest in, or in any other 
         manner advise or assist any person, firm, corporation or other entity
         engaged in, any business which involves the production, marketing or
         distribution, in the United States or Canada, of any products to
         improve the value of food animal products which are delivered by
         implant as such business (i) is conducted as of the date hereof by
         Vetlife, or (ii) may be conducted by Ivy Laboratories, Inc. ("Ivy") or
         Vetlife during the Restricted Period based on any products derived from
         the filings with the United States Food and Drug Administration (the
         "FDA") reflected on Schedule 1 attached hereto and any pending FDA
         filing reflected on Schedule 2 attached hereto in 


<PAGE>   74


         each case only in the industry referenced opposite such filing and (ii)
         any high oil corn products (collectively, the "Restricted Activities");

                      (b)  actively solicit for employment (including as an
         independent contractor), interfere with or endeavor to entice away (or
         attempt to do any of the foregoing) any of the directors, officers,
         employees or agents of Buyer or any Affiliate of Buyer, who was an
         employee of Vetlife prior to the Closing Date; or

                      (c) request or cause any lessees, owners or operators of
         any distributors, managed facilities, suppliers or customers with whom
         Buyer or any of its Affiliates has a business relationship in regard to
         any of the Restricted Activities to cancel or terminate any such
         business relationship with Buyer or any of its Affiliates. For purposes
         of this Agreement, "Affiliate" shall mean a person or entity that
         directly or indirectly, through one or more intermediaries, controls,
         is controlled by, or is under common control with CytRx, Vetlife or
         Buyer. Notwithstanding the foregoing, "Affiliate" shall not include (i)
         Vaxcel, Inc., a subsidiary of CytRx and (ii) any director or officer of
         CytRx or Vetlife or shareholder of CytRx owning 5% or more of its
         common stock (a "Shareholder").

                      1.2 For purposes of this Agreement, the "Restricted
         Period" shall mean (a) the period 


<PAGE>   75


         commencing on the date of this Agreement and ending on the fifth
         anniversary of the date of this Agreement and (b), with respect to the
         production, marketing or distribution by the Restricted Entities of (i)
         any high oil corn products or (ii) any product which contains the
         active pharmaceutical chemical Ivermectin, the period commencing on the
         date hereof and ending on December 31, 2008 and December 31, 2005,
         respectively.

                      1.3 Notwithstanding the provisions of Sections 1.1 and 1.2
         of this Agreement, nothing contained in this Agreement shall be deemed
         to limit or otherwise restrict in any way whatsoever the right of the
         Restricted Entities:

                 (a)  to engage in the development, production, distribution or 
         licensing of copolymers which, as of the date hereof, are licensed by
         CytRx to Vetlife; or

                  (b) to own any securities of any corporation which is publicly
         owned and traded but in an amount not to exceed at any one time five
         percent (5%) of any class of stock or securities of such corporation;
         Further, notwithstanding the provisions of Sections 1.1 and 1.2 of this
         Agreement, nothing contained in this Agreement shall be deemed to limit
         or otherwise restrict the sale, transfer or assignment in whatever form
         of any or all the interests in, or any or all of the Excluded Assets
         of, Vetlife and/or any of its present or future Affiliates to, or the
         subsequent 


<PAGE>   76


         management and operation of the businesses thereof by, any person,
         firm, corporation or other entity which now or at any time hereafter
         conducts, by itself or through any Affiliate, any Restricted
         Activities.

                      1.4 Sections 1.1, 1.2 or 1.3 shall not prohibit any Person
         that acquires all or substantially all of the assets, or 51% or more of
         the capital stock, of either CytRx or Vetlife, or in any other way
         becomes an Affiliate, from engaging in any Restricted Activities after
         such acquisition; provided, that such Person was engaged in such
         Restricted Activities at the time of such acquisition.

                      1.5 Neither Vetlife nor CytRx shall advise or assist any
         of its directors, officers or Shareholders in engaging in any of the
         Restricted Activities during the Restricted Period. To the knowledge of
         Vetlife and CytRx, none of their directors, officers, Shareholders or
         employees (other than Ed Fehnel and the Vetlife employees that may
         become employees of Buyer) are engaged in, or intend to engage in, any
         of the Restricted Activities during the Restricted Period.

                      2. Specific Performance; Damages. The parties acknowledge
         that it is not possible to measure in money alone the damages which
         would accrue to Buyer as a result of any breach by either Seller of the
         provisions of this Agreement. Therefore, if Buyer 


<PAGE>   77


         institutes any action or proceeding to enforce the provisions of this
         Agreement, Sellers each hereby waive the claim or defense that Buyer
         has or may have an adequate remedy at law and consents to the specific
         enforcement of the provisions of this Agreement in such suit or action
         and to the issuance of an order restraining the breach of this
         Agreement. To the extent it is possible to measure in money any damages
         accruing to Buyer as a result of any breach by either Seller of the
         provisions of this Agreement, Buyer will have the right to recover such
         damages.

                      3. Invalidity. The invalidity or unenforceability of any
         particular provision of this Agreement will not affect the other
         provisions of this Agreement, and this Agreement will be construed, in
         all respects, as if the invalid or unenforceable provision had been
         omitted from this Agreement, or, whenever possible, such provision will
         be construed and limited in such a manner and to the extent to make it
         valid and enforceable.

                      4. Benefit. This Agreement will inure to the benefit of
         Buyer and its successors and assigns including any successor through
         merger or consolidation.

                      5. Construction. This Agreement will be construed and
         governed in accordance with the laws of 


<PAGE>   78


         the State of New York without regard to principles concerning conflict
         of laws.

                      6. Attorneys' Fees. If any suit or action is brought to
         enforce or interpret this Agreement, the prevailing party will be
         entitled to recover its reasonable attorneys' fees and costs incurred
         in such suit or action, and in any appeal, from the nonprevailing
         party, as determined by the court or courts in which such suit, action
         or appeal is heard.

                      7. No Counterclaims. The existence of any claim or cause
         of action by the Restricted Entities against Buyer shall not constitute
         a defense to the enforcement by Buyer of the restrictive covenants set
         forth in Sections 1.1 and 1.2, but such claim or cause of action shall
         be litigated separately.

                      8. Successors and Assigns; Beneficiaries. This Agreement
         will be binding upon and shall inure to the benefit of the parties
         hereto and their respective successors and assigns. Except as expressly
         provided in this Agreement, nothing in this Agreement, expressed or
         implied, is intended to confer on any person or entity (other than the
         parties or their respective successors and permitted assigns) any
         rights, remedies, obligations or liabilities under or by reason of this
         Agreement.

                      9. Drafting. Each party acknowledges that its legal
         counsel participated in the preparation of this 


<PAGE>   79


         Agreement. The parties therefore stipulate that the rule of
         construction that ambiguities are to be resolved against the drafting
         party shall not be employed in the interpretation of this Agreement to
         favor any party against the other.

                      10. Section Captions. The section captions are for the
         convenience of the parties and will not affect the meaning or
         interpretation of any provision of this Agreement.

                      11. Notices. All notices, requests, demands and other
         communications made in connection with this Agreement shall be in

                            CONFIDENTIALITY AGREEMENT

                  AGREEMENT, made as of the 17th day of April, 1998, by and
among VetLife L.L.C., a Delaware limited liability company (the "Company"),
CytRx Corporation, a Delaware corporation ("CytRx"), and Vetlife, Inc., a
Delaware corporation and a subsidiary of CytRx ("Vetlife"). All capitalized
terms used herein and not otherwise defined shall have the same meanings
ascribed to such terms in the Acquisition Agreement (as such term is defined
below).

                                   WITNESSETH:

                  WHEREAS, contemporaneously with the date of this Agreement,
the parties have entered into an Acquisition Agreement, dated as of April 17,
1998, (the "Acquisition Agreement") pursuant to which the Company has acquired
from Vetlife all of the Assets; and

                  WHEREAS, each of the parties hereto have disclosed and will
continue to disclose to the others, or to their respective officers, employees,
financial advisors, accountants, legal counsel, lending institutions or other
agents and representatives (collectively, the "Representatives"), proprietary,
confidential or other non-public information (collectively, the "Information"),
relating to their respective businesses, and each party desires to maintain the
proprietary, confidential and non-public nature of the Information which has
been, or which will be, disclosed by it to the other parties.

                  NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:

                  1. The term "Information," with respect to any party hereto
disclosing Information (the "Disclosing Party"), does not include information
which (i) the party receiving the information (the "Receiving Party") can show
was already in the possession of such Receiving Party prior to disclosure by the
Disclosing Party, and which was not acquired or obtained from the Disclosing
Party or its Representatives (whether received before or after the date hereof),
(ii) is or becomes generally available to the public other than as a result of a
disclosure by the Receiving Party or its Representatives, (iii) becomes
available to the Receiving Party on a non-confidential basis from a source other
than the Disclosing Party or its Representatives, which source is not, to the
knowledge of the Receiving Party, prohibited from transmitting the information
to the Receiving Party by a legal, contractual or fiduciary obligation to the
Disclosing Party or (iv) does not derive independent economic value from not
being generally known to, and not being readily ascertainable by proper means
by, other persons who can obtain economic value from its disclosure or 


<PAGE>   84


use, and is not the subject of efforts that are reasonable under the
circumstances to maintain its secrecy.

                  2. Except as expressly permitted by this Agreement or as
authorized by the Disclosing Party in writing, neither the Receiving Party nor
any of its Representatives shall reveal or make known to any person, firm,
corporation or entity, the Information. The Information shall be used by the
Receiving Party and its Representatives solely for the purpose of consummating
the transactions contemplated by the Acquisition Agreement.

                  3. In the event that the Receiving Party is requested or
required (by oral questions, interrogatories, requests for information or
documents, subpoena, civil investigative demand or other process) to disclose
any Information, the Receiving Party shall provide the Disclosing Party with
prompt notice of any such request or requirement so that the Disclosing Party
may seek an appropriate protective order or waive compliance with this
Agreement. If, in the absence of a protective order or other remedy or the
receipt of a waiver by the Disclosing Party, the Receiving Party or its
Representatives are nonetheless, in the written opinion of counsel, legally
compelled to disclose Information to any tribunal or else stand liable for
contempt or suffer other censure or penalty, the Receiving Party or its
Representatives may, without liability hereunder, disclose to such tribunal only
that portion of the Information which such counsel advises is legally required
to be disclosed, provided that the Receiving Party exercises its best efforts to
preserve the confidentiality of the Information, including, without limitation,
by cooperating with the Disclosing Party to obtain an appropriate protective
order or other reliable assurance that confidential treatment will be accorded
the Information by such tribunal.

                  4. For purposes of this Agreement, Information received or
disclosed by Vetlife shall be deemed received or disclosed by CytRx.

                  5. Unless amended or terminated in writing by the parties,
this Agreement shall apply to any Information only for a period of five (5)
years from the date such Information is disclosed to either party.

                  6. Each party acknowledges that any breach of the covenants
contained in Paragraph 2 or 3 of this Agreement will result in irreparable
injury to the Disclosing Party, for which money damages could not adequately
compensate the Disclosing Party. In the event of any such breach or any
threatened breach, the Disclosing Party shall be entitled to have an injunction
or retraining order issued by any competent court of equity enjoining and
restricting the Receiving Party and its Representatives from breaching or
continuing any such breach. Such remedy shall not be deemed to be the exclusive
remedy, but 


<PAGE>   85


shall be in addition to all other remedies available at law or equity to the
Disclosing Party.

                  7.  Each party agrees to be responsible for any breach of this
Agreement by any of its respective affiliates and Representatives. For purposes
of this Agreement, a person shall be deemed to be affiliated with a party if
such person directly or indirectly, through one or more intermediaries,
controls, or is controlled by, or is under common control with such party.

                  8.  This Agreement shall be governed by and construed in
accordance with the laws of the State of New York.

                  9.  No amendment or alteration of the terms of this Agreement
shall be valid unless made in writing and signed by the parties hereto;
provided, however, that this Agreement shall apply only to disclosures made
prior to December 31, 2010.

                  10. This Agreement contains the entire agreement of the
parties with respect to the subject matter hereof and shall be binding upon and
inure to the benefit of the parties hereto and their successors and assigns.
This Agreement supersedes and preempts any prior understandings, agreements or
representations by or among the parties, written or oral, which may have related
to the subject matter hereof in any way.

                  11. This Agreement may be signed in counterparts with the same
effect as if the signatures to each counterpart were upon a single instrument,
and all such counterparts together shall be deemed an original of this
Agreement. For purposes of this Agreement, a facsimile copy of a party's
signature shall be sufficient to bind such party.

         IN WITNESS WHEREOF, the parties have executed this Agreement on the day
and year first above written.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Liquidity and Capital Resources

         At December 31, 1997 the Company had cash and short-term investments of
$5.9 million and net assets of $19.2 million, compared to $11.0 million and
$22.3 million, respectively, at December 31, 1996. Working capital totaled $7.1
million at December 31, 1997, compared to $10.2 million at December 31, 1996.

         Management believes that cash and investments on hand, combined with
interest income, operating revenues and the proceeds from the transactions
discussed below, will be sufficient to satisfy the Company's projected liquidity
and working capital needs through late 1999, but it is likely that additional
funding will be required to accomplish the necessary testing and data collection
procedures prescribed by the U.S. Food and Drug Administration for the
commercialization of any products for human use. Definitive statements as to the
time required and costs involved in reaching certain objectives for the
Company's products are difficult to project due to the uncertainties of the
medical research field. Requirements could vary depending upon the results of
research, competitive and technological developments, and the time and expense
required for governmental approval of products, some of which factors are beyond
management's control. CytRx anticipates that it may raise funds through equity
offerings. Additional funding for research and development expenditures may be
obtained through joint ventures and product licensing arrangements with other
companies.

         During 1996 and 1997, the Company received federal government funding
for certain research and development activities via several Small Business
Innovative Research (SBIR) grants. Most recently, the Company received a grant
from the U.S. Food and Drug Administration's Division of Orphan Drug Development
to support CytRx's Phase III clinical trial of FLOCOR. This grant will provide
approximately $400,000 over two years to help defray the overall costs of the
study. The Company intends to continue to seek government assistance for its
product development efforts.

         In October 1997, CytRx sold $2.0 million of convertible notes through a
private placement, realizing approximately $1.8 million in net proceeds. (See
Note 6 to Financial Statements.) CytRx has the option to sell an additional $2.0
million to the same investors under certain conditions.

         In February 1998, CytRx's wholly-owned subsidiary, Proceutics, Inc.
consummated a sale of substantially all of its non-real estate assets to Oread
Laboratories, Inc. ("Oread") for approximately $2.1 million. (See Note 12 to
Financial Statements.) Also, in February 1998, the Company entered into an
agreement with Alexandria Real Estate Equities, Inc. ("Alexandria") pursuant to
which Alexandria will purchase the building owned by Proceutics and assume the
existing lease with Oread. CytRx will also sell its building to Alexandria and
simultaneously

<PAGE>   3
execute a ten year lease. Total proceeds from this transaction, which is
expected to be consummated in the second quarter of 1998 will be $4.5 million.
(See Note 13 to Financial Statements.)

         On April 17, 1998, the Company and VetLife entered into an Acquisition
Agreement (the "Acquisition Agreement") with VetLife L.L.C., a Delaware limited
liability company ("VL LLC"), pursuant to which VL LLC acquired substantially
all of VetLife's assets related to VetLife's business of marketing and
distributing products that improve the value of food animal products to the
cattle industry (collectively, the "Assets") for a total purchase price
consisting of: (i) a cash payment of $3,500,000, subject to certain working
capital adjustments, (ii) an unsecured, subordinated promissory note in the
principal amount of $4,000,000 bearing interest at an annual rate of 12%, and
(iii) certain contingent payments based on future sales of specified products of
VL LLC and its affiliates that, if made in full, could total up to $5,500,000.
The sale of the Assets closed on the same day. 

         The Company has consulting agreements with various individuals and
companies for routine business activities including assistance with regulatory,
marketing, investor relations, and research and development activities. As of
December 31, 1997, there were no significant firm commitments pursuant to any of
such agreements and none of such agreements are with affiliates of the Company.

         At December 31, 1997 the Company had net operating loss carryforwards
for income tax purposes of approximately $44.6 million, which will expire in
2000 through 2012 if not utilized. The Company also has research and development
credits available to reduce income taxes, if any, of approximately $1.1 million
which will expire in 2000 through 2010 if not utilized. Based on an assessment
of all available evidence including, but not limited to, the Company's limited
operating history and lack of profitability, uncertainties of the commercial
viability of the Company's technology, the impact of government regulation and
healthcare reform initiatives, and other risks normally associated with
biotechnology companies, the Company has concluded that it is more likely than
not that these net operating loss carryforwards and credits will not be realized
and, as a result, a 100% deferred tax valuation allowance has been recorded
against these assets.

         The above statements regarding the Company's plans and expectations for
future financing are forward-looking statements that are subject to a number of
risks and uncertainties. The Company's ability to obtain future financings
through joint ventures, product licensing arrangements, equity financings or
otherwise is subject to market conditions and the Company's ability to identify
parties that are willing and able to enter into such arrangements on terms that
are satisfactory to the Company. There can be no assurance that the Company will
be able to obtain future financing from these sources. Additionally, depending
upon the outcome of the Company's fund raising efforts via its subsidiaries
discussed above, the accompanying financial information may not necessarily be
indicative of future operating results or future financial condition.

Results of Operations

         The following table presents the breakdown of consolidated results of
operations by operating unit for 1997, 1996 and 1995. Although the subsequent
discussion addresses the consolidated results of operations for CytRx and its
subsidiaries, management believes this presentation of net results by operating
unit is important to an understanding of the consolidated financial statements
taken as a whole.

</TABLE>

         Consolidated net sales from continuing operations for 1997 were
$878,000, as compared to $880,000 in 1996 and $513,000 in 1995. Cost of sales
from continuing operations was $354,000 in 1997, $235,000 in 1996, and $50,000
in 1995. 

         Investment income from continuing operations was $797,000 in 1997, as
compared to $1,169,000 in 1996 and $1,804,000 in 1995. The decrease for each
year is attributable to declining cash and investment balances. In 1995 CytRx
chose to convert the majority of its short-term investments into cash
equivalents. At January 1, 1995, the Company had $2.5 million in unrealized
losses as a result of 1994's dramatic increase in interest rates. By taking
advantage of strength in the bond market during the second quarter of 1995,
CytRx reduced its unrealized losses by $1.4 million, recording non-cash charges
of $1.1 million during 1995. These charges are shown as a separate line item in
the Consolidated Statements of Operations. Due to the higher yield on its
longer-term investments during the period in which these losses were incurred
and then recognized (February 1994 to June 1995), total investment income, net
of realized losses, exceeded the amount of potential investment income which
would have been realized had the Company avoided such losses by investing in
shorter-term securities.

         Research and development expenditures from continuing operations during
1997 were $4,690,000 versus $2,867,000 in 1996 and $7,071,000 in 1995. The
decrease from 1995 to 1996 was primarily due to a shift of personnel and capital
resources from the Company's internal research efforts to Proceutics, coupled
with a broader base of selling and administrative activities in Proceutics and
Vetlife to which overall facilities costs and shared services are allocated,
thereby reducing such allocations to research and development. Research and
development expenditures increased in 1997 as a result of the Company's
development activities for
<PAGE>   5

FLOCOR, including the completion of a Phase II clinical trial and preparation
for a Phase III trial which was initiated in March 1998. The Company also
devoted significant resources toward addressing manufacturing issues for FLOCOR.
In 1997, the Company recognized a $951,000 charge for acquired in-process
research and development as a result of Vaxcel's acquisition of Zynaxis (See
Note 5 to Financial Statements). The acquisition of this in-process research and
development did not significantly impact the Company's ongoing research and
development expenditures during 1997; however, the Company anticipates
significant future expenditures will be required to continue development of
these technologies into commercially viable products. Such expenditures will be
limited by Vaxcel's available capital resources.

         Selling, general and administrative expenses from continuing operations
during 1997 were $3,115,000 as compared to $2,577,000 in 1996 and $3,575,000 in
1995. Management believes that inflation had no material impact on the Company's
operations during the three year period ended December 31, 1997.

Year 2000

         The Year 2000 Issue is the result of computer programs being written
using two digits rather than four to define the applicable year. As a result,
those computer programs having time-sensitive software would recognize a date
using "00" as the year 1900 rather than the year 2000.

         Based on a recent assessment, the Company determined that its
accounting software will need to be updated or modified. This should be
accomplished through updates from the software manufacturer. The Company does
not expect any material costs associated with this modification or any
disruptions to its primary operations. The Company anticipates no other year
2000 problems which are reasonably likely to have a material adverse effect on
the Company's operations. There can be no assurance, however, that such problems
will not arise.

Impact of Recently Issued Accounting Standards

         In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement No. 130, Reporting Comprehensive Income ("Statement 130"). Statement
130 establishes new standards for the reporting and display of comprehensive
income and its components in a full set of general purpose financial statements.
These new standards require that all items recognized as components of
comprehensive income be reported in a financial statement that is displayed with
the same prominence as other financial statements. Statement 130 is effective
for fiscal years beginning after December 15, 1997. The adoption of Statement
130 will not impact the Company's consolidated financial statements.

         In June 1997, the FASB issued Statement 131, Disclosures About Segments
of an Enterprise and Related Information ("Statement 131"). Statement 131
changes the way public companies report segment information in annual financial
statements and also requires those companies to report selected segment
information in interim financial reports. Statement 131 is effective for periods
beginning after December 15, 1997. The adoption of Statement 131 will not have a
significant impact on the Company's consolidated financial statements.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                       CYTRX CORPORATION AND SUBSIDIARIES

1.       NATURE OF BUSINESS

         CytRx Corporation and its subsidiaries (Proceutics, Inc., Vaxcel, Inc.
and Vetlife, Inc.) (collectively the "Company") are engaged in the development
of pharmaceutical products including FLOCOR to treat acute sickle cell crisis
and other vascular diseases and technologies to improve the effectiveness of
vaccines. The Company also markets and distributes products to enhance food
animal growth.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Basis of Presentation - The consolidated financial statements include
the accounts of CytRx Corporation ("CytRx") together with those of its
majority-owned subsidiaries. All significant intercompany transactions have been
eliminated. Certain prior year amounts have been reclassified to conform to the
1997 financial statement presentation. As more thoroughly discussed in Note 12,
Proceutics, Inc. ("Proceutics") and Vetlife, Inc. ("Vetlife") are presented as 
discontinued operations for all periods presented.

         Reverse Stock Split - All share and per share information in the
accompanying consolidated financial statements and notes thereto has been
retroactively adjusted to reflect a one-for-four reverse stock split approved on
February 5, 1996 by the Company's stockholders, effective February 6, 1996.

         Cash Equivalents - The Company considers all highly liquid debt
instruments with an original maturity of 90 days or less to be cash equivalents.
Cash equivalents consist primarily of auction-market preferred stock, commercial
paper and amounts invested in money market accounts.

         Restricted Cash - In January 1996 Vetlife signed an agreement with IVY
Laboratories, Inc. ("IVY") to market and distribute IVY's line of FDA-approved
cattle growth products and devices in North America. In connection with the
agreement, Vetlife was required to obtain a letter of credit in the amount of $5
million in favor of IVY. Such unused letter of credit is collateralized by
approximately $5.3 and $5.9 million in cash equivalents and investments at
December 31, 1997 and 1996, respectively. Such collateral is presented as
long-term investments in the accompanying consolidated balance sheet. (See Note
12).

         Investments - Management determines the appropriate classification of
debt securities at the time of purchase and reevaluates such designation as of
each balance sheet date. Debt securities are classified as held-to-maturity when
the Company has the positive intent and ability to hold the securities to
maturity. Held-to-maturity securities are stated at amortized cost. Marketable
equity securities and debt securities not classified as held-to-maturity are
classified as




<PAGE>   11

available-for-sale. Available-for-sale securities are carried at fair value,
with the unrealized gains and losses reported in a separate component of
stockholders' equity. Realized gains and losses are included in investment
income and are determined on a first-in, first-out basis (see Note 3).

         Fair Value of Financial Instruments - The carrying amounts reported in
the balance sheet for cash and cash equivalents, investments (see Note 3),
accounts receivable, note receivable, accounts payable and convertible
debentures approximate their fair values. The carrying amount reported in the
balance sheet for long-term debt approximates its fair value. The fair value of
such long-term debt is estimated using discounted cash flow analyses based on
the Company's current incremental borrowing rate for similar types of borrowing
arrangements.

         Inventories - Inventories, which are comprised primarily of finished
cattle growth promotant products, are valued at the lower of cost or market
using the first-in, first-out (FIFO) method.

         Property and Equipment - Property and equipment are stated at cost and
depreciated using the straight-line method based on the estimated useful lives
(twenty years for buildings and five to seven years for equipment and furniture)
of the related assets.

         Acquired Developed Technology and Other Intangibles - Acquired 
developed  technology and other intangible assets, primarily goodwill, (See
Note 5) are amortized over their estimated useful lives (fifteen years) on a
straight-line basis. Management continuously monitors and evaluates the
realizability of recorded acquired developed technology and other intangible
assets to determine whether their carrying values have been impaired. In
accordance with Financial Accounting Standards Board ("FASB") Statement No.
121, Accounting for the Impairment of Long-Lived Assets, the Company records
impairment losses on long-lived assets used in operations when events and
circumstances indicate that the assets might be impaired and the undiscounted
cash flows estimated to be generated by those assets are less than the
carrying amount of those assets. During 1997, continued losses at Vaxcel
indicated that acquired developed technology of $3.5 million and goodwill of
$600,000 might be impaired. However, the Company's estimate of undiscounted
cash flows indicated that such carrying amounts were expected to be recovered.
Nonetheless, it is reasonably possible that the estimate of undiscounted cash
flows may change in the future resulting in the need to write-down those assets
to fair value.

         Patents and Patent Application Costs - Prior to 1995 the Company
capitalized the costs associated with obtaining patents on its technologies.
During the first quarter of 1995 the Company changed from deferring and
amortizing such costs to recording them as expenses when incurred because, even
though the Company believes the patents and underlying technology have
continuing value, the amount of future benefits to be derived therefrom is
uncertain. Accordingly, the new accounting method was adopted in recognition of
a possible change in estimated future benefits. Since the effect of this change
in accounting principle was inseparable from the effect of the change in
accounting estimate, such change was accounted for as a change in estimate in
accordance with Opinion No. 20 of the Accounting Principles Board. As a result,
the Company recorded a non-cash write-off of $1.4 million during 1995 ($.18 per
share). Future patent costs are expected to be expensed since the benefits to be
derived therefrom are likely to be uncertain.

         Basic and Diluted Loss per Common Share - In February 1997, the FASB
issued Statement No. 128, Earnings Per Share ("Statement 128"). Statement 128
replaced the calculation of primary and fully diluted loss per share with basic
and diluted loss per share. Unlike primary loss per share, the calculation of
basic loss per share




<PAGE>   12

excludes any dilutive effects of options, warrants and convertible securities.
Diluted loss per share is very similar to the previously reported fully diluted
loss per share. Loss per share amounts for all periods have been presented in
accordance with Statement 128 requirements.

         Basic and diluted loss per share are computed based on the weighted
average number of common shares outstanding. Common share equivalents (which may
consist of options, warrants and convertible debentures) are excluded from the
computation of diluted loss per share since the effect would be antidilutive.

         Shares Reserved for Future Issuance - The Company has reserved
approximately 2,238,000 of its authorized but unissued shares of common stock
for future issuance pursuant to stock options and warrants, convertible debt and
employee benefit plans.

         Revenue Recognition - Sales are recognized at the time the products are
shipped or services rendered. The Company does not require collateral or other
securities for sales made on credit. Revenues from collaborative research
arrangements and grants are generally recorded as the related costs are
incurred. The costs incurred under such arrangements approximated the revenues
reported in the accompanying statements of operations. License fees reported in
the accompanying statements of operations consist entirely of nonrefundable fees
received upon the signing of certain technology license and option agreements.
These fees were recognized as income when they were received. Such agreements
generally contain provisions for additional fees upon the achievement of certain
development milestones by the licensee and upon approval of the related
products, followed by a royalty based upon net sales. Such fees, if any, will be
recognized as income when they become receivable under the terms of the related
contracts.

         Sale of Stock by a Subsidiary - The Company does not recognize gains on
the sale of previously unissued stock of subsidiaries when there are significant
uncertainties regarding the Company's ability to ultimately realize its
investment in the subsidiary. Such gains are reflected as additional paid-in
capital in the Company's consolidated financial statements.

         Stock-based Compensation - The Company grants stock options for a fixed
number of shares to key employees and directors with an exercise price equal to
the fair market value of the shares at the date of grant. The Company accounts
for stock option grants in accordance with APB Opinion No. 25, Accounting for
Stock Issued to Employees ("APB 25"), and, accordingly, recognizes no
compensation expense for the stock option grants (see Note 8).

         In October 1995, the FASB issued Statement of Financial Accounting
Standards No. 123, Accounting for Stock-based Compensation ("Statement 123"),
which provides an alternative to APB 25 in accounting for stock-based
compensation issued to employees. However, the Company has continued to account
for stock-based compensation in accordance with APB 25.

         The Company also has granted a limited number of stock options to
consultants and certain third parties. These stock options generally expire
after ten years from the date of grant and have exercise prices equal to the
fair market value of the underlying common stock at the date of grant. The fair
value of the stock options granted to consultants and certain third parties was
immaterial.

         Concentrations of Credit Risk - Financial instruments that potentially
subject the Company to significant concentrations of credit risk consist
principally of cash investments. The Company maintains cash equivalents and
investments in large well-capitalized financial




<PAGE>   13

institutions and the Company's investment policy disallows investment in any
debt securities rated less than "investment-grade" by national ratings services.

         Use of Estimates - The preparation of the financial statements in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.

3.       Investments

         At January 1, 1995 the Company classified all of its investments as
available-for-sale. Proceeds from sales of available-for-sale securities during
1995 were $25.3 million. Net realized losses on sales of available-for-sale
securities during 1995 were $1.1 million.

         At December 31, 1997 and 1996 the Company has classified all of its
investments as held-to-maturity, as summarized below (in thousands):

5.       Acquisition of Zynaxis, Inc.

         In December 1996 CytRx, Vaxcel, Inc. ("Vaxcel") and Zynaxis, Inc.
("Zynaxis") signed an agreement whereby Zynaxis would be merged with a
wholly-owned subsidiary of Vaxcel. At that time Zynaxis was a publicly-held
biotechnology company engaged in the development of certain vaccine
technologies. The transaction was approved by the Zynaxis stockholders at a
meeting held on May 21, 1997 and was consummated as of that date.

         Under the terms of the agreement all of the outstanding shares of
Zynaxis were converted into shares of Vaxcel based upon certain exchange ratios
defined in the agreement, resulting in the issuance of an aggregate of 1.4
million (12.5%) of the outstanding (post-merger) shares of Vaxcel common stock
(at $2.91 per share) to former Zynaxis stockholders at the date of closing. The
merger was treated as a purchase by Vaxcel and constituted a tax-free
reorganization for Zynaxis stockholders. The results of operations of Zynaxis
are included in the statement of operations since May 21, 1997.

         Pursuant to the agreement, CytRx was to provide up to $2 million to
Zynaxis under a secured credit facility during the period prior to closing of
the merger, at which time the outstanding principal and interest was to be
contributed to the capital of Vaxcel, together with additional equity in the
amount of $4 million less the outstanding principal and interest of the secured
note. At the time of closing the outstanding principal and interest of the
secured note to Zynaxis was approximately $1.7 million, resulting in a net cash
infusion from CytRx to Vaxcel of approximately $2.3 million. In addition, at the
date of closing, Vaxcel issued to CytRx a one-year warrant entitling CytRx to
purchase a number of shares of Vaxcel common stock equal to the amount of
capital which may be necessary for Vaxcel to satisfy requirements for inclusion
in the Nasdaq SmallCap Market, divided by one-half of the $2.91 per share
transaction price at the date of closing.

         In accordance with the provisions of APB Nos. 16 and 17, all
identifiable assets acquired, including identified intangible assets and
liabilities assumed, were assigned a portion of the purchase price based on
their respective fair values. The fair values of the acquired developed


<PAGE>   15


technology and incomplete research and development were determined based on an
independent appraisal. A summary of the allocation of the purchase price is a
follows (in thousands):

</TABLE>

         As a result of this transaction, CytRx owns 87.5% of the outstanding
Vaxcel common stock and former Zynaxis stockholders own the remaining 12.5%. An
unrealized gain of $2,706,000 relating to the sale of 12.5% of Vaxcel common
stock is reflected in stockholders' equity. The change to equity reflecting
CytRx's proportionate share of the increase in Vaxcel's equity related to the
shares issued in connection with the acquisition of Zynaxis was recorded as an
equity transaction since realization of the gain was not assured.

         The following table presents unaudited pro forma operating results for
the years ended December 31, 1997 and 1996, as if the acquisition of Zynaxis had

6.       6% CONVERTIBLE DEBENTURES

         On October 22, 1997, the Company privately placed (the "Note Sale")
with certain investors (the "Investors") $2,000,000 of convertible notes (the
"Debentures") which mature in October, 2001. The Debentures may be converted
into CytRx common stock on and after December 21, 1997 at a price equal to the
lesser of 85% of the average closing bid price for the 10 days preceding the
conversion, or $5.68 per share (the "Conversion Price"). Such beneficial
conversion feature was determined to have a fair value of $265,000 at the date
of issuance and has been amortized to interest expense from the date of issuance
through the date the Debentures first became convertible. The Debentures were
sold at par and bear interest at a rate of 6% per annum. The terms of the
Debentures grant CytRx the right to redeem the Debentures at 110% of par if the
Conversion Price falls below $4. Also in connection with the Note Sale, the
Investors were issued two year warrants to purchase 40,000 shares of CytRx
common stock at an exercise price of $5.68. The fair value of such warrants was
determined to be insignificant.



<PAGE>   16

         In February 1998, $400,000 of the Debentures were converted into
161,608 shares of common stock, and an additional $400,000 of Debentures were
redeemed by the Company.

7.       COMMITMENTS AND CONTINGENCIES

         Lease Commitments - Rental expense under operating leases during 1997,
1996 and 1995 approximated $74,000, $70,000 and $69,000, respectively. Minimum
annual future obligations for operating leases are $167,000, $50,000 and $45,000
in 1998, 1999 and 2000, respectively. Aggregate minimum future subrentals the
Company expects to receive under noncancellable subleases through January 2000
total approximately $60,000 at December 31, 1997.

         Purchase Commitments - At December 31, 1997, the Company had
outstanding firm purchase commitments for inventory of approximately $46.0
million related to minimum annual purchase volumes under certain contracts
covering a period of four years. Such contracts are with the supplier of the
Company's cattle growth promotant products. Purchases from this supplier totaled
$7,270,000 and $2,000 in the years ended December 31, 1997 and 1996, 
respectively. As of April 17, 1998, these purchase commitments were dissolved
(See Note 12).

8.       STOCK OPTIONS AND WARRANTS

         The Company and its subsidiary, Vaxcel, have stock option plans
pursuant to which certain key employees and directors are eligible to receive
incentive and/or nonqualified stock options to purchase shares of the Company's
or the subsidiary's common stock. The options granted under the plans generally
become exercisable over a three year period from the dates of grant and have
lives of ten years. Additionally, the Company has granted warrants to purchase
shares of the Company's common stock to its President and Chief Executive
Officer subject to vesting criteria as set forth in his employment agreement;
such warrants have lives of ten years from the dates of grant. Exercise prices
of all options and warrants are set at the fair market values of the common
stock on the dates of grant.

         A summary of the Company's stock option and warrant activity and
related information for the years ended December 31 is shown below. In January
1995 the Company repriced certain

employee stock options and warrants, resulting in the net cancellation of 91,060
options and warrants.

</TABLE>

         The exercise prices for options outstanding as of December 31, 1997
ranged from $1.00 to $3.25. The weighted average remaining contractual life of
those options is 6.6 years.

         The Company and its subsidiary have elected to follow APB 25 and
related Interpretations in accounting for their employee stock options because,
as discussed below, the alternative fair value accounting provided for under
Statement 123 requires use of option valuation models that were not developed
for use in valuing employee stock options. Under APB 25, because the exercise
prices of the Company's and its subsidiary's employee stock options equal the
fair market value of the underlying stock on the date of grant, no compensation
expense is recognized. Stock options granted to consultants and certain other
third parties are valued at their fair value on the date of grant and have been
immaterial to date.

         Pro forma information regarding net loss and loss per share is required
by Statement 123, which also requires that the information be determined as if
the Company and its subsidiary had accounted for their employee stock options
granted subsequent to December 31, 1994 under the fair value method of




<PAGE>   18
that Statement.

         The fair value for the Company's options was estimated at the date of
grant using a Black-Scholes option pricing model with the following assumptions:

         The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's and its subsidiary's employee stock options
have characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the
fair value estimate, in management's opinion, the existing models do not
necessarily provide a reliable single measure of the fair value of their 
employee stock options.

         For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting periods. The Company's
pro forma information is as follows (in thousands, except per share data):

</TABLE>

         Statement 123 is applicable only to options granted subsequent to
December 31, 1994; therefore, its proforma effect will not be fully reflected
until 1998.

9.       ADOPTION OF SHAREHOLDER PROTECTION RIGHTS PLAN

         Effective April 16, 1997, the Company's Board of Directors declared a
distribution of one Right for each outstanding share of the Company's common
stock to stockholders of record at the close of business on May 15, 1997 and for
each share of common stock issued by the Company thereafter and prior to a
Flip-in Date (as defined below). Each Right entitles the registered holder to
purchase from the Company one ten-thousandth (1/10,000th) of a share of Series A
Junior Participating Preferred Stock, at an exercise price of $30. The Rights
are generally not exercisable until 10 business days after an announcement by
the Company that a person or group of affiliated persons (an "Acquiring Person")
has acquired beneficial ownership of 15% or more of the Company's then
outstanding shares of common stock (a "Flip-in Date").

         In the event the Rights become exercisable as a result of the
acquisition of shares, each Right will enable the owner, other than the
Acquiring Person, to purchase at the Right's then current exercise price a
number of shares of common stock with a market value equal to twice the exercise
price. In addition, unless the Acquiring Person owns more than 50% of the
outstanding shares of common stock, the Board of Directors may elect to exchange
all outstanding Rights (other than those owned by such Acquiring Person) at an
exchange ratio of




<PAGE>   19

one share of common stock per Right. All Rights that are owned by any person on
or after the date such person becomes an Acquiring Person will be null and void.

         The Rights have been distributed to protect the Company's stockholders
from coercive or abusive takeover tactics and to give the Board of Directors
more negotiating leverage in dealing with prospective acquirers.

10.      RETIREMENT PLAN

         The Company maintains a defined contribution retirement plan (the
"Plan") covering employees of the Company. Historically, at the Board of
Directors' discretion, the Company has matched 50% of the participant's
contribution with common stock. The Company's matching contribution vests over 3
years. Total expense for the Plan for the years ended December 31, 1997, 1996
and 1995 was $164,000, $143,000 and $139,000, respectively, of which $105,000,
$77,000 and $-0- related to the discontinued operations of Proceutics and
Vetlife for the years ended December 31, 1997, 1996 and 1995, respectively.

11.      INCOME TAXES

         For income tax purposes, CytRx and its subsidiaries have an aggregate
of approximately $44.6 million of net operating losses available to offset
against future taxable income, subject to certain limitations. Such losses
expire in 2000 through 2012. They also have an aggregate of approximately $1.1
million of research and development credits available for offset against future
income taxes which expire in 2000 through 2010.

         Deferred income taxes reflect the net effect of temporary differences
between the financial reporting carrying amounts of assets and liabilities and
income tax carrying amounts of assets and liabilities. The components of the
Company's deferred tax assets and liabilities are as follows:

<PAGE>   20


         Based on assessments of all available evidence as of December 31, 1997
and 1996, management has concluded that the respective deferred income tax
assets should be reduced by valuation allowances equal to the amounts of the
deferred income tax assets.

          The amount of net operating loss carryforwards generated by Zynaxis
prior to the merger was $31,000,000.  The use of pre-acquisition operating loss
carryforwards is subject to limitations imposed by the Internal Revenue Code.
The Company anticipates that these limitations will affect utilization of the
carryforwards prior to expiration.  Therefore, for financial reporting purposes
the Company has recorded a deferred tax asset of $1,277,000, giving effect to
these limitations with a corresponding valuation allowance of $1,277,000.  When
realized, the tax benefit of these loss carryforwards will be applied to
reduce acquired developed technology and other intangibles related to the
acquisition of Zynaxis.

12.      DISCONTINUED OPERATIONS

         Sale of Proceutics
         On February 16, 1998, the Company consummated a sale of substantially
all of the assets of Proceutics other than real estate to Oread Laboratories,
Inc. ("Oread") for approximately $2.1 million. Proceutics retained its real
estate assets consisting of a laboratory building which it is leasing to Oread.
The Company expects a gain related to the sale of Proceutics which will be
recognized in 1998.

         Net losses associated with Proceutics included in income (loss) from
discontinued operations were approximately $(138,000), $(1,448,000) and $-0- for
the years ended December 31, 1997, 1996 and 1995 respectively. (See Note 14). A
summary of the assets and liabilities of Proceutics which were sold, and which
are included in the consolidated balance sheets at December 31, 1997 and 1996 
are as follows (in thousands):

         Sale of VetLife
         On April 17, 1998, the Company and VetLife, entered into an Acquisition
Agreement with VL LLC pursuant to which VL LLC acquired substantially all of
VetLife's Assets for a total purchase price consisting of: (i) a cash payment of
$3,500,000, subject to certain working capital adjustments, (ii) an unsecured,
subordinated promissory note in the principal amount of $4,000,000 bearing
interest at a annual rate of 12%, and (iii) certain contingent payments based on
future sales of specified products of VL LLC and its affiliates that, if made in
full, could total up to $5,500,000. The sale of the Assets closed on the same
day. The Company will retain the $5.3 million in investing that were pledged to
secure a letter of credit (See Note 2).  The Company expects a gain related to
this transaction which will be recognized in 1998.

         Included in income (loss) from discontinued operations were
approximately $868,000, $(1,151,000) and $-0- related to VetLife's cattle
marketing operations for the years ended December 31, 1997, 1996 and 1995

13.  POTENTIAL SALE OF REAL ESTATE

         On February 23, 1998, the Company entered into an agreement with
Alexandria Real Estate Equities, Inc. ("Alexandria") pursuant to which CytRx and
Proceutics would sell the two buildings owned by them at 150 and 154 Technology

Agreement, Proceutics' rights and obligations under the lease to Oread (See Note
12) would be assigned to Alexandria and CytRx would lease the build at 154
Technology Parkway from Alexandria. The Company expects that this transaction
will be consummated in the second quarter of 1998 and will result in a gain 
which will be recognized in 1998.

Titermax). Financial information for operations by industry segment at December

The Board of Directors and Stockholders
CytRx Corporation

         We have audited the accompanying consolidated balance sheets of CytRx
Corporation as of December 31, 1997 and 1996, and the related consolidated
statements of operations, stockholders' equity, and cash flows for each of the
three years in the period ended December 31, 1997. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

         In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
CytRx Corporation at December 31, 1997 and 1996 and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1997, in conformity with generally accepted accounting principles.
