                         NOTES TO FINANCIAL STATEMENTS
                                  (Unaudited)


1.   Significant Accounting Policies:

     In the opinion of management, the accompanying financial statements contain
     all adjustments (consisting only of normal recurring items) necessary to
     present fairly the financial position of Anesta Corp. (the Company) as of
     June 30, 2000, the results of its operations for the three and six months
     ended June 30, 2000 and 1999, and its cash flows for the six months ended
     June 30, 2000 and 1999. The results of operations for the periods presented
     are not necessarily indicative of the results to be expected for the full
     year period.

     Certain information and footnote disclosures normally included in financial
     statements prepared in accordance with generally accepted accounting
     principles have been condensed or omitted. It is suggested that these
     financial statements be read in conjunction with the Company's Annual
     Report on Form 10-K for the period ended December 31, 1999 and Quarterly
     Report on Form 10-Q for the period ended March 31, 2000.

     Net Loss Per Share

     Basic and diluted earnings per share are computed in accordance with
     Statement of Financial Accounting Standards (SFAS) No. 128, Earnings Per
     Share (EPS). Basic EPS excludes dilution and is computed by dividing
     income available to common stockholders by the weighted-average number of
     common shares outstanding for the period. Diluted EPS reflects the
     potential dilution from convertible securities or contracts to issue common
     stock. Common equivalent shares are excluded from the computation of
     diluted EPS when their effect is antidilutive. As of June 30, 2000, options
     to purchase 1,927,647 shares of common stock at prices between $9.25 and
     $25.1875 per share were outstanding. As of June 30, 1999, options to
     purchase 1,322,487 shares of common stock at prices between $5.25 and
     $25.1875 were outstanding. None of these options were included in the
     computation of diluted loss per share because the effect would have been
     antidilutive.

2.   Cash, Cash Equivalents and Marketable Debt Securities:

     At June 30, 2000, the Company maintained a majority of its cash, cash
     equivalents and marketable debt securities in two banks in San Francisco,
     California.

3.   Income Taxes:

     The provision for income taxes for the three and six months ended June 30,
     2000 and 1999 is related solely to state income taxes.

4.   Revolving/Term Promissory Note Agreements:

     In January 1995, the Company secured a revolving/term loan in the amount of
     $1,500,000. This loan converted to a 10 year term loan on May 15, 1995. In
     March 1997 and July 1999, the Company borrowed an additional $800,000 and
     $500,000, respectively.

                                  (Unaudited)


4.   Revolving/Term Promissory Note Agreements, Continued

     As of June 30, 2000, the balance of the loan is $2,000,000. Annual
     principal payments in the amount of $333,333 will be made on approximately
     July 15 for the next 6 years beginning on July 15, 2000. Interest at the
     rate of 8% is paid quarterly. As of June 30, 2000, borrowings under the
     agreement are collateralized by a certificate of deposit in the amount of
     $2,040,000, which is maintained in a bank in Salt Lake City, Utah.

5.   Collaborative Relationships:

     In 1989, Anesta entered into a research and development, license, supply
     and distribution agreement (1989 Agreement) with Abbott Laboratories
     (Abbott). Under the agreement, as amended, Anesta granted to Abbott the
     exclusive right to make, use and market in the United States OTS products
     resulting from technology owned or licensed by Anesta consisting of OTS
     fentanyl. Under the 1989 Agreement, Abbott provided development funding and
     milestone payments and was obligated to pay royalties and other payments on
     product sales. Through June 30, 2000, Abbott had paid a total of
     $10,050,000 for the development of Anesta's OTS fentanyl product line.
     Anesta anticipates it will receive no further payments in the future from
     Abbott.

     On March 13, 2000, Anesta announced that it had reaquired the U.S.
     marketing rights for Actiq with Abbott. Effective April 2000, Anesta has
     responsibility for the sales and marketing of Actiq in the U.S. As part of
     the reacquisition, Anesta made cash payments to Abbott of $23,850,000,
     which amount is included in other assets in the accompanying balance sheet.
     Anesta is also obligated to make on-going earn-out payments to Abbott until
     May 1,2005. Capitalized amounts related to this agreement, which relate
     primarily to the acquired marketing rights, are being amortized on a
     straight-line basis over a ten year expected life. Abbott will continue to
     manufacture Actiq and Fentanyl Oralet for Anesta in the U.S. for a period
     of 24 to 36 months, after which Anesta has the right to manufacture such
     products.


6.   Subsequent Events

     On July 17, 2000, the Company announced that Cephalon, Inc. (Cephalon) will
     acquire all of the outstanding shares of Anesta in a tax-free, stock-for-
     stock transaction intended to be accounted for as a pooling of interests.
     Upon completion of the transaction, Anesta shareholders will receive 0.4765
     shares of newly-issued Cephalon common stock for each share of Anesta they
     own. As part of the transaction, Anesta has agreed to a termination fee of
     $15 million, which is payable under certain conditions. The boards of
     directors of both companies have unanimously approved the proposed merger,
     which is subject to the approval of Anesta shareholders, regulatory
     agencies and customary closing conditions. The merger is expected to be
     completed during the fourth quarter of 2000. Under the terms of the merger
     agreement, Anesta will become a wholly-owned subsidiary of Cephalon.
