                         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
     March 31, 2000, the results of its operations for the three months ended
     March 31, 2000 and 1999, and its cash flows for the three months ended
     March 31, 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.

     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 March 31, 2000,
     options to purchase 1,578,292 shares of common stock at prices between
     $5.25 and $25.1875 per share were outstanding.  As of March 31, 1999,
     options to purchase 1,399,305 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 March 31, 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 months ended March 31, 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.

4.   Revolving/Term Promissory Note Agreements, Continued
     -----------------------------------------

     As of March 31, 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 7% is paid monthly.  As of March 31, 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 March 31, 2000, Abbott had paid a total
     of $10,050,000 for the development of Anesta's OTS fentanyl product line.

     On March 13, 2000, Anesta announced that it had renegotiated the U.S.
     marketing rights for Actiq with Abbott.  Effective April 2000, Anesta will
     have responsibility for the sales and marketing of Actiq in the U.S. As
     part of the renegotiation, Anesta will make cash payments to Abbott and is
     obligated to make on-going earn-out payments to Abbott until the end of the
     first patent covering oral transmucosal fentanyl citrate.  Through March
     31, 2000, Anesta had made cash payments to Abbott of $5,000,000, which
     amount is included in other assets in the accompanying balance sheet. The
     Company also made payments to Abbott totaling $18,850,000 in May 2000.
     Capitalized amounts related to this agreement will be 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.

     In January 1998, the Company entered into an exclusive agreement with Grupo
     Ferrer Internacional S.A. (Ferrer), a leading private Spanish
     pharmaceutical company, for the marketing, sales and distribution rights of
     Anesta's OTS fentanyl product line, including Actiq, in Spain and Portugal.
     Ferrer made a payment to the Company and Anesta will manufacture such
     products for Ferrer.

     In June 1998, the Company entered into an exclusive agreement with
     Laboratoire L. Lafon (Lafon), a leading private French pharmaceutical
     company, for the marketing, sales and distribution rights of Anesta's OTS
     fentanyl product line, including Actiq, in France.  Under terms of the
     agreement, Lafon made payments to the Company and Anesta will manufacture
     such products for Lafon.

     In February 1999, the Company entered into a 12-month option agreement with
     Novartis Consumer Health, Inc. (Novartis) involving the Company's
     proprietary OTS for drug delivery. Under the terms of the option agreement,
     Novartis and the Company assessed the worldwide commercial opportunity of
     potential products combining Novartis compounds with the Company's OTS.
     Currently, the Company and Novartis are in discussions about the
     possibility of a definitive licensing agreement.

     In May 1999, the Company entered into an exclusive agreement with Swedish
     Orphan AB (SWO), a leading private Swedish pharmaceutical company, for the
     marketing, sales and distribution rights of Anesta's OTS fentanyl product
     line, including Actiq, in Scandinavia (Denmark, Finland, Iceland, Norway
     and Sweden).  Under terms of the agreement, SWO made payments to the
     Company and Anesta will manufacture such products for SWO.

     In September 1999, the Company entered into an exclusive agreement with
     Elan Pharma International, a unit of Elan Corporation, plc (Elan), a
     leading public Irish pharmaceutical company, for the marketing, sales and
     distribution rights of Anesta's OTS fentanyl product line, including Actiq,
     in Austria, Belgium, Germany, Greece, Ireland, Italy, Luxembourg,
     Netherlands, Philippines, Switzerland, Taiwan and the United Kingdom.
     Under terms of the agreement, Elan made payments to the Company and Anesta
     will manufacture such products for Elan.

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

The following Management's Discussion and Analysis of Financial Condition and
Results of Operations contains forward-looking statements which involve risks
and uncertainties.  The Company's actual results could differ materially from
those anticipated in these forward-looking statements as a result of certain
factors discussed in this section.  Additional risks and uncertainties are
described in the Company's most recently filed Annual Report on Form 10-K for
the fiscal year ended December 31, 1999.

Results of Operations

Revenues.

Total revenues increased by $1,124,000 or 547.8% for the three months ended
March 31, 2000 as compared to the corresponding period in 1999.  The increase is
primarily a result of product sales of Actiq in the U.S. and recognition of
upfront fees paid by Elan, Novartis and Ferrer.

In March 2000, Anesta renegotiated the U.S. marketing rights for Actiq and
Fentanyl Oralet with Abbott. Under terms of the agreements, Anesta will have
primary responsibility for sales and marketing in the U.S.  As part of the
renegotiation, Anesta will make cash payments to Abbott and is obligated to make
on-going earn-out payments to Abbott until the end of the first patent covering
oral transmucosal fentanyl citrate.  Abbott will continue to manufacture Actiq
and Fentanyl Oralet in the U.S. for Anesta for a period of 24 to 36 months,
after which Anesta will have the right to manufacture such products.   Anesta
recognizes revenue when Abbott ships product against a customer order. Anesta's
gross margin therefore is directly affected by Abbott's manufacturing costs.
Anesta is also obligated to pay a small royalty to the University of Utah
Research Foundation on its sales of Actiq and Fentanyl Oralet.

Operating Costs and Expenses.

Cost of goods sold increased by $239,000 or 2,594.5% for the three months ended
March 31, 2000 as compared to the corresponding period in 1999.  The increase is
a result of product sales of Actiq in the U.S.

Research and development expenses increased by $538,000 or 24.4% for the three
months ended March 31, 2000 as compared to the corresponding period in 1999.
The increase is due to higher expenditures related to additional research and
development programs, increased number of personnel, and continuing support for
Actiq in Europe.  The Company expects that its research and development expenses
will increase in the future as a result of increased expenses related to the
hiring of additional personnel, preclinical studies, clinical trials, product
development, manufacturing process development and clinical manufacturing
activities.

Depreciation expense increased by $10,000 or 13.1% for the three months ended
March 31, 2000 as compared to the corresponding period in 1999. The increase is
due primarily to the Company's remodeling of additional facilities.

Marketing, general and administrative expenses increased by $178,000 or 9.9% for
the three months ended March 31, 2000 as compared to the corresponding period in
1999.  The increase is due primarily to higher expenditures for personnel,
corporate development activities, European operations, marketing research and
continuing support of Actiq sales activities.  The Company expects that its
marketing and general and administrative expenses will significantly increase in
the future as a result of the increased support required for Actiq marketing and
sales activities, European operations, including Actiq pre-launch activities in
Europe, and corporate development activities.

Non Operating Income (Expense).

Interest income decreased by $35,000 or 3.4% for the three months ended March
31, 2000 as compared to the corresponding period in 1999.  The decrease is
primarily due to a decrease in the balance of invested net proceeds from the
Company's public offering in December 1998.

Interest expense increased by $9,000 or 35.7% for the three months ended March
31, 2000 as compared to the corresponding period in 1998.  The increase is
primarily due to higher net borrowings under the term note (See Note 4 to
Financial Statements).

Income Taxes.

The provision for income taxes in 2000 and 1999 relates solely to state income
taxes.  The Company recognized no tax benefit from its losses in those years.

Net Loss.

As a result of the increase in total revenues, the increase in research and
development activities, the increase in marketing, general and administrative
expenses, the decrease in interest income and other factors discussed above, the
net loss for the three months ended March 31, 2000 was $2,818,133 or $0.21 per
share as compared to $2,889,635 or $0.22 per share for the same period in 1999.

Liquidity and Capital Resources

As of March 31, 2000, the Company had cash and cash equivalents totaling
$27,117,000, $2,040,000 in a certificate of deposit used as collateral for a
revolving/term loan (See Note 4 to Financial Statements) and $35,897,000 in
marketable debt securities which are available for sale.  Thus cash, cash
equivalents, certificate of deposit and marketable debt securities totaled
$65,054,000 as of March 31, 2000.  Cash in excess of immediate requirements is
invested according to the Company's investment policy, which provides guidelines
with regard to liquidity and return, and, wherever possible, seeks to minimize
the potential effects of concentration of credit risk.

The Company used cash in operating activities of $3,489,000 for the three months
ended March 31, 2000 compared to $4,047,000 for the corresponding period in
1999.  The decrease in cash used in the period is a direct result of lower
working capital requirements.

During the three months ended March 31, 2000, the Company made capital
expenditures of approximately $12,000 as compared to capital expenditures of
$29,000 during the corresponding period in 1999.  During the three months ended
March 31, 2000, the Company had a net decrease of marketable debt securities of
$23,135,000.  This compares to a net increase in marketable debt securities of
$29,245,000 during the corresponding period in 1999.  During the three months
ended March 31, 2000, other assets increased by approximately $5,000,000 as a
result of payments to Abbott under the renegotiated marketing agreement. The
Company also made payments to Abbott related to the agreement totaling
$18,850,000 in May 2000.

During the three months ended March 31, 2000, the Company realized cash proceeds
of $743,000 relating to the exercise of stock options.  During the three months
ended March 31, 1999 the Company realized cash proceeds of $570,000 relating to
the exercise of stock options.

The Company's future capital requirements could be substantial and will depend
on, and could increase as a result of, many factors, including progress of the
Company's research and development programs; the results and costs of
preclinical and clinical testing of the Company's products, if developed; the
time and costs involved in obtaining regulatory approvals; the costs involved in
filing patents; the time and costs involved in developing and maintaining
collaborative research relationships; the costs associated with potential
commercialization of its products; and administrative and legal costs.  The
Company believes

                                       10
<PAGE>

that existing capital resources will be sufficient to meet the Company's capital
needs through at least the end of 2001.

The Company believes that it is prudent to monitor existing cash balances in
order to fund the activities which the Company believes are necessary to
continue its growth.  Therefore, the Company periodically evaluates market
conditions and various financing alternatives for obtaining funds to augment
existing cash balances.

Other Matters.

The Company has reviewed all other recently issued, but not yet adopted,
accounting standards in order to determine their effects, if any, on the results
of operations or financial position of the Company.  Based on that review, the
Company believes that none of these pronouncements will have a significant
effect on current or future earnings or operations.

     7.3  Legal Proceedings.
          -----------------

               (a) Notice of Claim. If any legal proceedings shall be
                   ---------------
          instituted, or any claim or demand made, against an indemnified party
          in respect of which an indemnifying party may be liable hereunder, or
          if either party hereto for any reason shall believe that it has a
          claim against the other pursuant to the indemnity provisions set forth
          in this Agreement, then the indemnified party or the party believing
          it has a claim against the other, as the case may be (in either case,
          the "Indemnified Party"), shall give prompt written notice hereunder
               -----------------
          to the indemnifying party or the party against whom the party giving
          notice believes it has a claim, as the case may be (in either case,
          the "Indemnifying Party") and shall use best efforts to send such
               ------------------
          notice no later than fifteen (15) days of the Indemnified Party's own
          notice of such claim; provided, however, that the failure to provide
          such prompt notice shall not affect the Indemnifying Party's
          obligation to indemnify except to the extent of the Indemnifying
          Party's actual damages caused by such failure. Such notice shall
          specify in reasonable detail the date such underlying claim or belief
          first was asserted or arose, the nature of the loss(es) for which
          payment is claimed, and the amount payable in respect thereto.

               (b) Opportunity to Defend. If an Indemnifying Party receives
                   ---------------------
          notice pursuant to Subsection 7.3(a) hereof, the Indemnifying Party
          may, at its sole option, elect to defend against the claims,
          liabilities and/or losses which are the subject of such notice, except
          that Seller shall have no authority to adjust, compromise or settle
          any claim involving any right of Purchaser to ownership or use of any
          of the Assets or to defend any claim which, if adversely determined,
          would materially impair the commercial prospects of the Products. If
          the Indemnifying Party elects to defend, then the Indemnified Party
          shall have the right to participate in such defense at its own
          expense, trial counsel shall be chosen by the Indemnifying Party and
          such trial counsel shall be reasonably satisfactory to the Indemnified
          Party, the costs of which shall be borne by the

                                       19
<PAGE>

          Indemnifying Party, and the Indemnified Party agrees to cooperate with
          the Indemnifying Party in such defense.

               (c) Reimbursement. If the amount of any actual loss indemnified
                   -------------
          against hereunder shall at any time subsequent to payment of any
          indemnity payable hereunder, be reduced by any recovery, settlement or
          other payment, then the amount of such reduction, less any expense
          incurred by the party receiving such recovery, settlement or other
          payment in connection therewith, shall be repaid promptly to the
          Indemnifying Party.

     7.4  Further Conditions. In no event shall a party seeking indemnity
          ------------------
hereunder, compromise or otherwise settle any such claim without the
Indemnifying Party's prior written consent, which consent shall not be
unreasonably withheld.

     7.5  Survival. Except as otherwise provided herein, the provisions of
          --------
Article VII hereof shall survive the Closing in accordance with their terms.

     7.6  Purchaser's Insurance. Purchaser shall obtain and keep in force
          ---------------------
during the term of its indemnity obligations to Seller under this Agreement
insurance policies providing the following minimum levels of coverage: general
comprehensive liability insurance covering each occurrence of bodily injury and
property damage in an amount of not less than One Million Dollars ($
1,000,000.00) per occurrence with an aggregate of Two Million Dollars
($2,000,000.00) in any calendar year with the special endorsement providing
coverage for Product and Completed Operations Liability in an amount of not less
than Ten Million Dollars ($10,000,000.00); and an umbrella policy in an amount
not less than Four Million Dollars ($4,000,000.00). The insurance policy shall
be endorsed to provide for written notification to Seller by the insurer not
less than thirty (30) days prior to cancellation, expiration, or modification. A
certificate of insurance evidencing compliance with this Section and referencing
this Agreement shall be furnished to Seller by Purchaser within ten (10) days of
the Closing, Date, or, in the event of insurance renewal, within ten (10) days
of such renewal.

                   -----------------------------------------

     8.1  Use of Names. As soon as practicable following the Closing,
          ------------
Purchaser shall use commercially reasonable efforts to seek the appropriate
approvals to market and sell the Products bearing labeling and using literature
not containing the name "Abbott Laboratories." Prior to Purchaser receiving such
approval, Seller shall use commercially reasonable efforts to exhaust its
then-current supply of labels containing the name Abbott Laboratories. Promptly
upon receipt of such approval and in accordance with any deadlines or other
timing requirements contained therein, Seller shall use commercially reasonable
efforts to make the transition to literature and labels consistent with such
approval. Nothing herein shall be construed as a grant of any rights to
Purchaser to the name "Abbott Laboratories", except that Purchaser may use
Seller's existing inventories of literature for Products that bear such name (so
long as Purchaser maintains its insurance and indemnity obligations hereunder).

     8.2  Notification of Third Parties. Seller and Purchaser shall cooperate
          -----------------------------
with one another in the notification to customers, regulatory agencies
(including but not limited to FDA and DEA), vendors, key opinion leaders,
clinicians, pharmacists, wholesalers and the Rocky Mountain Poison Control
Center of the transactions contemplated by this Agreement. Such notification
shall be in such form as is reasonably satisfactory to Seller and Purchaser.

          ------------------
Date, Seller shall refer customer telephone inquiries respecting the Products to
Purchaser.

          --------------------
Purchaser shall issue a press release substantially in the form attached as
Exhibit K and during the first one hundred eighty (180) days after the Effective
Date, each party shall obtain the written consent of the other party prior to
making any other written public statement concerning this Agreement and the
transactions contemplated hereby, which consent shall not be unreasonably
withheld. Except as provided in Section 8.1, Purchaser and Seller shall not use
the name of the other party in any marketing or advertising materials without
prior written approval of the other party. The foregoing shall not be deemed to
prevent either party from: (a) making any public disclosure which may be
required of either party or its Affiliates at any time under the federal
securities

                                       21
<PAGE>

laws or by the rules and regulations of any national securities exchange upon
which the securities of either party or its Affiliates are traded; provided,
however, that the party required to make such disclosure shall, except where
impracticable, give reasonable advance notice to the other party of such
disclosure and use commercially reasonable efforts to secure confidential
treatment of such information; or (b) disclosing the substance or details of
this Agreement to its financial advisors, legal advisors, bona fide potential
corporate partners or any person or entity who has a bona fide interest in
investing in or acquiring substantially all of the assets or securities of such
party, provided that such party has used commercially reasonable efforts in good
faith to obtain a binder of confidentiality.

     8.5  Pre-Closing and Transition Period.
          ---------------------------------

               (a) Seller's Operations Prior to Closing. During the period

          contemplated by this Agreement, Seller shall continue to perform its
          obligations under the Original Agreements in the ordinary and usual
          course in a manner consistent with its performance of such obligations
          prior to the Effective Date.

               (b) Seller's Covenants Prior to Closing. During the period
                   -----------------------------------
          between the Effective Date and the Closing Date, Seller shall not,
          outside the ordinary course of business and without Purchaser's prior
          written consent, which consent shall not be unreasonably withheld: (i)
          take any actions that can reasonably be expected to increase the
          amounts due by Seller under the Contracts; (ii) become a party to an
          acquisition transaction specifically pertaining to Products; (iii)
          commence a legal proceeding with respect to the Assets, the Anesta
          Technology, the Products or the Licensed Products; or (iv) enter into
          any transaction or take any other action outside the ordinary course
          of business with respect to the Products or Licensed Products.

<PAGE>

          those interested members of the Targeted Sales Force. On or about
          March 23, 2000, Purchaser shall send out by express mail services
          offers for employment to those members of the Targeted Sales Force
          that Purchaser selects. Such offers shall remain open until 5:00 p.m.
          CST on March 28, 2000. Thereafter, Purchaser shall be subject to the
          terms and conditions of Section 3.3.

               (d) Transitional Activities. During the Transition Period, in
                   -----------------------
          addition to the manufacture and shipping obligations of Seller under
          the Supply Agreement, Seller also shall perform the Transitional
          Activities on behalf of Purchaser. On a quarterly basis during the
          Transition Period, Seller shall reconcile the net amount owed
          Purchaser from the sale of Products to third parties. Such
          reconciliation shall be performed in a manner consistent with the
          reconciliation example set forth in Exhibit L. Seller shall pay
          Purchaser all amounts due according to such reconciliation not later
          than thirty (30) days after the end of the quarter for which such
          reconciliation was performed. Such payment shall be made by wire
          transfer to the First Security Bank of Utah, or such other bank as
          Anesta shall specify from time to time. Concurrent with such wire
          transfer, Seller shall transmit to Purchaser a report summarizing the
          calculations performed pursuant to the reconciliation. The parties
          shall cooperate to effect the orderly transition of the Transitional
          Activities from Seller to Purchaser.

               (e) Assistance. During the Transition Period, if requested by
                   ----------
          Purchaser, Seller shall provide Purchaser reasonable levels of non-
          technical assistance in the transfer to Purchaser of Seller's business
          and operations relating to the Assets, the Products and the Licensed
          Products. Seller shall provide such assistance to Purchaser in
          specific areas and functions, including, without limitation, those
          areas and functions set forth in Exhibit M. Seller shall remain
          responsible for the salaries of Seller's personnel participating in
          such assistance efforts, but Purchaser shall reimburse Seller for all
          travel, lodging and meals expenses incurred by such personnel.

          Transition Period, Seller shall administer such returns in accordance
          with its Hospital Products Division's standard return goods policy.
          The cost of these returns shall be charged to Purchaser in accordance
          with the reconciliation example set forth in Exhibit L.

               (c) Post-Transition Period. For all Products sold after the

          such Products.

          Abbott facilities as of the Closing Date ("Abbott Inventory"): (i) the

unauthorized use of such Confidential Information, but no less than reasonable

provided, that no such assignment in such instance shall relieve the assigning
party of its obligations hereunder, and provided further that either party may

covenant or agreement contained in this Agreement (or in any other agreement
between the parties) as to which there is no inaccuracy or breach.

                                   ---------

                   ALTERNATIVE DISPUTE RESOLUTION PROCEDURE

     The parties recognize that bona fide disputes as to certain matters may
arise from time to time during the term of this Agreement which relate to either
party's rights and/or obligations. To have such a dispute resolved by this
Alternative Dispute Resolution ("ADR") provision, a party first must send
written notice of the dispute to the other party for attempted resolution by
good faith negotiations between their respective presidents (or their
equivalents) of the affected subsidiaries, divisions, or business units within
twenty-eight (28) days after such notice is received (all references to "days"
in this ADR provision are to calendar days).

     If the matter has not been resolved within twenty-eight (28) days of the
notice of dispute, or if the parties fail to meet within such twenty-eight (28)
days, either party may initiate an ADR proceeding as provided herein. The
parties shall have the right to be represented by counsel in such a proceeding.

1.   To begin an ADR proceeding, a party shall provide written notice to the
     other party of the issues to be resolved by ADR. Within fourteen (14) days
     after its receipt of such notice, the other party may, by written notice to
     the party initiating the ADR, add additional issues to be resolved within
     the same ADR.

2.   Within twenty-one (21) days following receipt of the original ADR notice,
     the parties shall select a mutually acceptable neutral to preside in the
     resolution of any disputes in this ADR proceeding. If the parties are
     unable to agree on a mutually acceptable neutral within such period, either
     party may request the President of the CPR Institute for Dispute Resolution
     ("CPR"), 366 Madison Avenue, 14th Floor, New York, New York 10017, to
     select a neutral pursuant to the following procedures:

     (a)    The CPR shall submit to the parties a list of not less than five (5)
            candidates within fourteen (14) days after receipt of the request,
            along with a Curriculum Vitae for each

                                       i
<PAGE>

            candidate. No candidate shall be an employee, director, or
            shareholder of either party or any of their subsidiaries or
            affiliates.

     (b)    Such list shall include a statement of disclosure by each candidate
            of any circumstances likely to affect his or her impartiality.

     (c)    Each party shall number the candidates in order of preference (with
            the number one (1) signifying the greatest preference) and shall
            deliver the list to the CPR within seven (7) days following receipt
            of the list of candidates. If a party believes a conflict of
            interest exists regarding any of the candidates, that party shall
            provide a written explanation of the conflict to the CPR along with
            its list showing its order of preference for the candidates. Any
            party failing to return a list of preferences on time shall be
            deemed to have no order of preference.

     (d)    If the parties collectively have identified fewer than three (3)
            candidates deemed to have conflicts, the CPR immediately shall
            designate as the neutral the candidate for whom the parties
            collectively have indicated the greatest preference. If a tie should
            result between two candidates, the CPR may designate either
            candidate. If the parties collectively have identified three (3) or
            more candidates deemed to have conflicts, the CPR shall review the
            explanations regarding conflicts and, in its sole discretion, may
            either (i) immediately designate as the neutral the candidate for
            whom the parties collectively have indicated the greatest
            preference, or (ii) issue a new list of not less than five (5)
            candidates, in which case the procedures set forth in subparagraphs
            2(a) - 2(d) shall be repeated.

3.   No earlier than twenty-eight (28) days or later than fifty-six (56) days
     after selection, the neutral shall hold a hearing to resolve each of the
     issues identified by the parties. The ADR proceeding shall take place at a
     location agreed upon by the parties. If the parties cannot agree, the
     neutral shall designate a location other than the principal place of
     business of either party or any of their subsidiaries or affiliates.


                                      ii
<PAGE>

4.   At least seven (7) days prior to the hearing, each party shall submit the
     following to the other party and the neutral:

     (a)   a copy of all exhibits on which such party intends to rely in any
           oral or written presentation to the neutral;

     (b)   a list of any witnesses such party intends to call at the hearing,
           and a short summary of the anticipated testimony of each witness;

     (c)   a proposed ruling on each issue to be resolved, together with a
           request for a specific damage award or other remedy for each issue.
           The proposed rulings and remedies shall not contain any recitation of
           the facts or any legal arguments and shall not exceed one (1) page
           per issue.

     (d)   a brief in support of such party's proposed rulings and remedies,
           provided that the brief shall not exceed twenty (20) pages. This page
           limitation shall apply regardless of the number of issues raised in
           the ADR proceeding.

     Except as expressly set forth in subparagraphs 4(a) - 4(d), no discovery
     shall be required or permitted by any means, including depositions,
     interrogatories, requests for admissions, or production of documents.

5.   The hearing shall be conducted on two (2) consecutive days and shall be
     governed by the following rules:

     (a)    Each party shall be entitled to five (5) hours of hearing time to
            present its case. The neutral shall determine whether each party has
            had the five (5) hours to which it is entitled.

     (b)    Each party shall be entitled, but not required, to make an opening
            statement, to present regular and rebuttal testimony, documents or
            other evidence, to cross-examine witnesses,

                                      iii
<PAGE>

            and to make a closing argument. Cross-examination of witnesses shall
            occur immediately after their direct testimony, and cross-
            examination time shall be charged against the party conducting the
            cross-examination.

     (c)    The party initiating the ADR shall begin the hearing and, if it
            chooses to make an opening statement, shall address not only issues
            it raised but also any issues raised by the responding party. The
            responding party, if it chooses to make an opening statement, also
            shall address all issues raised in the ADR. Thereafter, the
            presentation of regular and rebuttal testimony and documents, other
            evidence, and closing arguments shall proceed in the same sequence.

     (d)    Except when testifying, witnesses shall be excluded from the hearing
            until closing arguments.

     (e)    Settlement negotiations, including any statements made therein,
            shall not be admissible under any circumstances. Affidavits prepared
            for purposes of the ADR hearing also shall not be admissible. As to
            all other matters, the neutral shall have sole discretion regarding
            the admissibility of any evidence.

6.   Within seven (7) days following completion of the hearing, each party may
     submit to the other party and the neutral a post-hearing brief in support
     of its proposed rulings and remedies, provided that such brief shall not
     contain or discuss any new evidence and shall not exceed ten (10) pages.
     This page limitation shall apply regardless of the number of issues raised
     in the ADR proceeding.

7.   The neutral shall rule on each disputed issue within fourteen (14) days
     following completion of the hearing. Such ruling shall adopt in its
     entirety the proposed ruling and remedy of one of the parties on each
     disputed issue but may adopt one party's proposed rulings and remedies on
     some issues and the other party's proposed rulings and remedies on other
     issues. The neutral shall not issue any written opinion or otherwise
     explain the basis of the ruling.

                                      iv
<PAGE>

8.   The neutral shall be paid a reasonable fee plus expenses. These fees and
     expenses, along with the reasonable legal fees and expenses of the
     prevailing party (including all expert witness fees and expenses), the fees
     and expenses of a court reporter, and any expenses for a hearing room,
     shall be paid as follows:

     (a)    If the neutral rules in favor of one party on all disputed issues in
            the ADR, the losing party shall pay 100% of such fees and expenses.

     (b)    If the neutral rules in favor of one party on some issues and the
            other party on other issues, the neutral shall issue with the
            rulings a written determination as to how such fees and expenses
            shall be allocated between the parties. The neutral shall allocate
            fees and expenses in a way that bears a reasonable relationship to
            the outcome of the ADR, with the party prevailing on more issues, or
            on issues of greater value or gravity, recovering a relatively
            larger share of its legal fees and expenses.

9.   The rulings of the neutral and the allocation of fees and expenses shall be
     binding, non-reviewable, and non-appealable, and may be entered as a final
     judgment in any court having jurisdiction.

10.  Except as provided in paragraph 9 or as required by law, the existence of
     the dispute, any settlement negotiations, the ADR hearing, any submissions
     (including exhibits, testimony, proposed rulings, and briefs), and the
     rulings shall be deemed Confidential Information. The neutral shall have
     the authority to impose sanctions for unauthorized disclosure of
     Confidential Information.

11.  All disputes referred to ADR, the statute of limitations, and the remedies
     for any wrong that may be found, shall be governed by the laws of the State
     of Illinois.

     right to punitive damages.

13.  The hearings shall be conducted in the English language.

14.  The parties shall not have ex parte communications with the neutral during
     the pendancy of the ADR proceeding before such neutral.

To the extent permissible under applicable laws and regulations, Abbott shall
grant Anesta reference rights to all Drug Master Files ("DMFs") necessary to
support Anesta's New Drug Applications ("NDAs") for Product and to enable Anesta
to assume manufacture of the Product upon expiration or earlier termination of

                                       3
<PAGE>

modified from time to time by agreement of the parties. Anesta shall reimburse
Abbott for Abbott's actual costs of making any label copy changes. During the
term of this Agreement, Abbott shall submit to the DEA bulk drug quantity
requests required to support Anesta's forecasts of Product.

     2.3.2 Quality Control. Abbott shall apply its quality control procedures
           ---------------
and in-plant quality control checks on the manufacture of Product for Anesta in
the same manner as Abbott applies such procedures and checks to products that
Abbott manufactures and sells for its own account. In addition, Abbott shall
test and release Product in accordance with the test methods described in the
documents referenced in Section 1.6 to ensure that Product conforms to the
Product Specifications. The parties each acknowledge that the documents
referenced in Section 1.6 establish procedures to obtain mutual consent for any
changes to Product Specifications to assure cGMP compliance, and each party
hereby agrees to abide by the procedures set forth therein.

     2.3.3 Audits. Anesta quality assurance and regulatory affairs personnel
           ------
shall have the right, upon reasonable written notice to Abbott, to conduct
during normal business hours a general quality assurance audit and inspection of
Abbott's quality assurance and regulatory records and production facilities
relating to the manufacture of Product, and special follow-up audits as
necessary. The general quality assurance audits and inspections may be conducted
once each calendar year. Visits by Anesta to Abbott's production facilities may
involve the transfer of Confidential Information and shall be subject to the
terms of Article V hereof. The results of such audits and inspections shall be
considered Confidential Information under Article V and shall not be disclosed
to third persons, including, but not limited to, the FDA and other government
regulatory agencies, unless required by law. Anesta shall use its commercially
reasonable efforts to provide Abbott with prior written notice of such legally
required disclosure, but if the circumstances of such disclosure make prior
notice impracticable, Anesta shall notify Abbott in writing of such disclosure
promptly thereafter.

     2.3.4 Product Disposition. Abbott shall appropriately and fully
           -------------------
document the validation, manufacturing, testing (incoming, in-process, release
and stability) and all process deviations and material nonconformances according
to approved batch records, test methods, protocols, quality action limits and
Product Specifications. Abbott shall provide to Anesta a

                                       4

certificate of analysis, not later than ten (10) days after the release of each
batch or lot, confirming that such batch or lot meets the Product
Specifications.

     2.3.5 Notification of Complaints; Adverse Event Reporting. Anesta shall
           ---------------------------------------------------
be responsible for complaint receipt, opening, investigation (excluding
manufacturing related issues), customer response, closure and any subsequent
required Adverse Event reporting to the FDA. Abbott, as the manufacturer of the
Product, shall provide reasonable assistance in failure analysis and complaint
investigation. Abbott shall forward to Anesta any Product complaint Abbott
receives within one (1) business day of Abbott's receipt and knowledge of such
complaint. Anesta shall notify Abbott of any Product complaints that may involve
issues of Abbott's manufacturing or packaging of Product in sufficient time to
allow Abbott to evaluate the complaints and assist Anesta in responding to such
complaints.

     2.3.6 Commercial Stability. Abbott shall test Product lots (in any
           --------------------
strength) kept on stability for compliance with the applicable Product stability
protocols contained in the Product NDAs. Abbott shall submit the data and
records of any applicable investigations for review and approval by Anesta prior
to incorporating such information into any internal or external reports. Abbott
shall communicate to Anesta that a Product lot does not meet Product
Specifications within three (3) business of days of learning of such confirmed
results so that Anesta may consider and determine the appropriate regulatory
action. Abbott shall reasonably cooperate with Anesta in taking all appropriate
and required actions under applicable regulations with respect to such Product
lots. Abbott shall invoice Anesta for the atypical (non-planned) stability
maintenance costs incurred by Abbott as a result of additional requirements
initiated by or attributable to Anesta. Further, the parties acknowledge that
Abbott has been conducting a thirty-six (36) month stability program for Actiq
commenced prior to the Effective Date and scheduled to be completed by June 30,
2000, and commenced performing, prior to the Effective Date, stability testing
of the first six (6) lots of each strength of Actiq. Abbott shall continue the
ongoing thirty-six (36) month stability program for Actiq through June 30, 2000,
and will continue the ongoing stability testing for the first six (6) lots of
each strength of Actiq during the term of this Agreement.

resulting from or relating to the manufacture of Products.

     2.4   Exclusive Shipping. For the term of this Agreement, Abbott shall be
           ------------------
solely responsible for shipping finished Product only to Anesta customers that
have the appropriate authorization from the DEA, including, without limitation,
primary wholesalers and hospitals in the United States, as provided in Section
2.6. Notwithstanding the foregoing in this Section 2.4, Abbott shall not be

Termination Agreement. Upon expiration of the Transition Period and thereafter,
Abbott shall invoice Anesta monthly for Product delivered pursuant to Section
2.6. Anesta shall make payment net thirty (30) days from the date of receipt of
Abbott's invoice. A late payment service charge of one and one-half percent
(1.5%) per month (or the highest amount allowed by law, if lower than 1.5%)
shall be paid by Anesta on all past due accounts. Abbott shall provide notice to
Anesta of past due amounts at least ten (10) days prior to the application of
any late payment service charge.

     2.5.3 Taxes. Anesta shall pay any federal, state, county or municipal sales
           -----
or use tax, excise, customs charges, duties or similar charge, or any other tax

charge lawfully assessed or charged on the manufacture, sale or transportation
of Product sold pursuant to this Agreement.

     2.6   Delivery. Abbott shall deliver Product to Anesta, F.C.A. Abbott's
           --------
plant or other facility at Abbott Park, Illinois or other facility the parties
may agree to in writing, packaged and labeled for shipment to such third parties
as Anesta designates in its purchase orders or otherwise in writing from time to

     2.7    Orders and Forecasts
            --------------------

     2.7.1  First Order Estimate. Anesta shall provide Abbott with a written
            --------------------
estimate of Anesta's monthly requirements for Product for the [...***...]
following the expiration of the Transition Period (the "Initial Forecast
Period") not later [...***...] Such estimate shall be a rolling forecast and
Anesta shall provide a quarterly update to such rolling forecast not later than
ninety (90) days prior to the beginning of the next quarterly period. Subject to
Subsection 2.7.3 below, Abbott acknowledges that such quantities are estimates
only. Within twenty (20) days of receipt of the initial rolling forecast and
each quarterly update, Abbott shall confirm in writing that it shall be able to
manufacture the quantities of Product listed in each rolling forecast, or if
Abbott cannot so confirm, Abbott shall advise Anesta in writing of the quantity
of Product Abbott shall be able to manufacture for the period of such forecast.
Notwithstanding the foregoing, Abbott shall use commercially reasonable efforts
to manufacture one hundred percent (100%) of the quantities of Product listed in
Anesta's rolling forecast, and after confirming that it shall be able to
manufacture a particular quantity of Product, Abbott shall not revoke such
confirmation or revise such quantity downward. If Abbott determines that it
cannot manufacture a quantity of Product previously confirmed by Abbott, the
parties shall meet and confer to discuss the circumstances giving rise to
Abbott's determination and the appropriate means to address them.

     2.7.2  Scheduling. Abbott and Anesta shall cooperate fully in estimating
            ----------

           ---------------
the terms of this Agreement and none of the provisions of such purchase order
shall be applicable, except those specifying quantity ordered, delivery dates,
special shipping instructions and invoice information. Abbott may reject
Anesta's purchaser order only if: (a) such purchase order sets forth shipping
instructions, delivery dates, invoice information or other material information
which are inconsistent with this Agreement; or (b) the total amount in such
purchase order exceeds the forecast for the relevant quarter by more than
[...***...] If either of such conditions occurs, Abbott shall notify Anesta of
such rejection and the basis for it within thirty (30) days of receipt of
Anesta's purchase order.

     2.8   Guarantees and Warranties
           -------------------------

     2.8.1 Abbott's Guarantee. Abbott guarantees to Anesta that Product Abbott
           ------------------

municipal law in which the definitions of adulteration and misbranding are
substantially the same as those contained in the Federal Food, Drug and Cosmetic
Act, as such Act and such laws are constituted and effective at the time of
delivery and will not be an article which may not under the provisions of
Sections 404 and 505 of such Act be introduced into interstate commerce.

           ----------------------
Anesta, its affiliates, officers, directors and employees from and against all
claims, causes of action, settlement costs, including reasonable attorneys'
fees, losses or liabilities of any kind related to this Agreement and asserted
by third persons that arise out of or are attributable to: (a) any intentional,
wrongful or negligent act or omission on the part of Abbott's employees, agents

supplied by Abbott resulting from Abbott's failure to manufacture Product in
accordance with the terms hereunder.

intends to base a claim for indemnification (an "Indemnity Claim") under this
Section. The indemnifying party shall have the right to participate jointly with
the indemnified party in the indemnified party's defense, settlement or other
disposition of any Indemnity Claim.

     2.8.7 Settlement of Indemnity Claims. With respect to any Indemnity Claim

manner, and as to which the indemnifying party shall have acknowledged in
writing the obligation to indemnify the indemnified party hereunder, the
indemnifying party shall have the sole right to defend, settle or otherwise
dispose of such Indemnity Claim, on such terms as the indemnifying party, in its
sole discretion, shall deem appropriate; provided, that, the indemnifying party
shall provide reasonable evidence of its ability to pay any damages claimed and
with respect to any such settlement shall have obtained the written release of
the indemnified party from the Indemnity Claim. The indemnifying party shall
obtain written consent from the indemnified party (which such consent shall not

dispose of any Indemnity Claim if, as a result thereof, the indemnified party
would become subject to injunctive or other equitable relief or the business of

     2.9   Product Recalls and Withdrawals.
           -------------------------------

     2.9.1 Responsibilities. In the event (a) any United States governmental or
           ----------------
regulatory authority issues a request, directive or order that a Product be
recalled or withdrawn, (b) a court of competent jurisdiction orders such recall
or withdrawal or (c) Anesta determines, after consultation with Abbott, that a
recall or withdrawal is necessary or advisable (each a "Recall"), Anesta shall,
at Anesta's sole cost and expense, conduct any Recall, unless the Recall was
caused by the manufacture, packaging, storage, or handling of the recalled
Product by Abbott. In the event the Recall was caused by Abbott as described
above, Abbott promptly shall reimburse Anesta for all direct costs of the Recall
upon submission to Abbott by Anesta of an itemized statement thereof. However,
as circumstances giving rise to the Recall are identified, the parties shall
meet to: (v) jointly review the appropriateness and/or scope of the Recall; (w)
determine which party should initiate the Recall with the FDA and the customer
base; (x) mutually agree to the impacted customer population; (y) determine the
timing and logistics of the Recall; and (z)

                                      10

mutually agree to the language used in any recall letter, telephone script and
media or other public announcement. For purposes of this Section 2.9, the
expenses of Recall shall include, but not be limited to, the expenses of
notification and destruction or return of the recalled Product and all other
costs incurred in connection with such Recall.

     2.9.2 Recall Dispute. If the parties do not agree as to the circumstances
           --------------
giving rise to the Recall, and those circumstances are specifically and solely
related to disputed test results, then representative samples of the Product
subject to Recall shall be submitted to a mutually acceptable third party
laboratory, which shall determine whether such recalled Product meets the
Product Specifications. The parties agree that such laboratory's determination
shall be final and determinative. The party against whom the third party tester
rules shall bear the reasonable costs of the third party testing. If the third
party tester rules that the batch meets the Product Specifications, Anesta shall
bear the costs of the recall. If the third-party tester rules that the batch
does not meet Product Specifications, Abbott shall bear the costs of the Recall.

     2.10  Purchase of Manufacturing Equipment. Upon the expiration or earlier
           -----------------------------------

license to such Technology in the Field, as that term is defined in the
Termination Agreement. During the period of such negotiations, Abbott shall not
convey to a third party the right to practice such Technology; provided, however
that if the parties do not reach an agreement as to the terms under which Anesta

Anesta, in its sole discretion, deems patentable any improvement or invention
related to Anesta's proprietary technology, know-how or rights relating to the
Product, then Anesta shall be entitled to apply for patent protection on such
improvements or inventions at its expense and risk.

                  (c) Upon the breach of Sections 2.3(b) or (c) of the
         Termination Agreement by the other party if the breach is not cured in
         accordance with the terms and conditions thereunder.

         4.3      Strategic Termination.  Anesta may terminate this Agreement
                  ----------------------
 as follows:

                  (a) by giving Abbott ninety (90) days written notice, if
         Anesta determines, in its sole discretion, that Anesta's manufacturing
         capacity is sufficient to meet its United States supply requirements
         for Actiq and Fentanyl Oralet, whether manufactured according to the
         Product Specifications or using other specifications; or

         4.4      Reimbursement Upon Termination. Upon termination pursuant to
                  ------------------------------
this Article IV, Anesta shall reimburse Abbott for Abbott's cost of all supplies
purchased and on hand or on order, if such supplies were ordered by Abbott based
on firm purchase orders or Anesta's rolling forecast of Product and such
supplies cannot be reasonably used by Abbott for other purposes. Abbott shall
invoice for amounts due hereunder. Payment shall be made pursuant to
Subparagraph 2.5.2.

         4.5      Return of Inventory. In the event of any termination, Abbott
                  -------------------
shall return any remaining inventory of Product to Anesta at Anesta's expense,
unless such termination shall have been as a result of a breach of this

expense. Prior to the effective date of such termination, the parties shall meet
in good faith and confer in order to determine the amount of money Anesta shall
pay Abbott for such inventory.

         5.1      Non-Disclosure. The parties recognize that, during the term of
                  --------------
this Agreement, each party may exchange Confidential Information. Abbott shall
not disclose to third persons Confidential Information received from Anesta, and
shall not use Confidential Information disclosed to it by Anesta for Abbott's
benefit (other than in the performance of its obligation hereunder) or for the
benefit of any third person. Anesta shall not disclose to third persons
Confidential Information received from Abbott, and Anesta shall not use
Confidential Information disclosed to it by Abbott for Anesta's benefit (other
than in the performance of its obligations hereunder) or for the benefit of any
third person. For the purposes of this Agreement, the terms and conditions of
this Agreement shall be considered as Confidential Information.

         5.2      Limited Rights to Disclosed Confidential Information.
                  ----------------------------------------------------
Notwithstanding the above, nothing contained in this Agreement shall preclude
Anesta or Abbott from utilizing Confidential Information as may be necessary in

manufacturing Product pursuant to this Agreement. The obligations of the parties
relating to Confidential Information shall expire five (5) years after the
termination of this Agreement.

         5.3      Requests for Disclosure of Confidential Information. If either
                  ---------------------------------------------------
party is requested to disclose any Confidential Information in connection with a
legal or administrative proceeding, such party shall give the other party prompt
notice of such request. The other party may seek an appropriate protective order
or other remedy and/or waive compliance with the provisions of this Agreement.
If such party seeks a protective order or other remedy, the other party shall
cooperate. If such party fails to obtain a protective order or waive compliance

including strikes, lockouts, job actions, boycotts, fires, explosions, floods,
shortages of material or energy, or other unforeseeable causes beyond the
control and without the fault or negligence of the party so affected. The

are encountered which interfere with production of Product at Abbott's Lake

agreed upon action plan to transfer production to another Abbott plant. Parties
shall meet, after the execution of this Agreement and at the request of either
party, to discuss and define such an action plan.

                        Alternative Dispute Resolution
                        ------------------------------

The parties recognize that bona fide disputes as to certain matters may arise
from time to time during the term of this Agreement which relate to either
party's rights and/or obligations. To have such a dispute resolved by this
Alternative Dispute Resolution ("ADR") provision, a party first must send
written notice of the dispute to the other party for attempted resolution by
good faith negotiations between their respective presidents (or their
equivalents) of the affected subsidiaries, divisions, or business units within
twenty-eight (28) days after such notice is received (all references to "days"
in this ADR provision are to calendar days).

If the matter has not been resolved within twenty-eight (28) days of the notice
of dispute, or if the parties fail to meet within such twenty-eight (28) days,
either party may initiate an ADR proceeding as provided herein. The parties
shall have the right to be represented by counsel in such a proceeding.

1.     To begin an ADR proceeding, a party shall provide written notice to the
       other party of the issues to be resolved by ADR. Within fourteen (14)
       days after its receipt of such notice, the other party may, by written
       notice to the party initiating the ADR, add additional issues to be
       resolved within the same ADR.

2.     Within twenty-one (21) days following receipt of the original ADR notice,
       the parties shall select a mutually acceptable neutral to preside in the
       resolution of any disputes in this ADR proceeding. If the parties are
       unable to agree on a mutually acceptable neutral within such period,
       either party may request the President of the CPR Institute for Dispute
       Resolution ("CPR"), 366 Madison Avenue, 14th Floor, New York, New York
       10017, to select a neutral pursuant to the following procedures:
<PAGE>

       (a)    The CPR shall submit to the parties a list of not less than five
              (5) candidates within fourteen (14) days after receipt of the
              request, along with a Curriculum Vitae for each candidate. No
              candidate shall be an employee, director, or shareholder of either
              party or any of their subsidiaries or affiliates.

       (b)    Such list shall include a statement of disclosure by each
              candidate of any circumstances likely to affect his or her
              impartiality.

       (c)    Each party shall number the candidates in order of preference
              (with the number one (1) signifying the greatest preference) and
              shall deliver the list to the CPR within seven (7) days following
              receipt of the list of candidates. If a party believes a conflict
              of interest exists regarding any of the candidates, that party
              shall provide a written explanation of the conflict to the CPR
              along with its list showing its order of preference for the
              candidates. Any party failing to return a list of preferences on
              time shall be deemed to have no order of preference.

       (d)    If the parties collectively have identified fewer than three (3)
              candidates deemed to have conflicts, the CPR immediately shall
              designate as the neutral the candidate for whom the parties
              collectively have indicated the greatest preference. If a tie
              should result between two candidates, the CPR may designate either
              candidate. If the parties collectively have identified three (3)
              or more candidates deemed to have conflicts, the CPR shall review
              the explanations regarding conflicts and, in its sole discretion,
              may either (i) immediately designate as the neutral the candidate
              for whom the parties collectively have indicated the greatest
              preference, or (ii) issue a new list of not less than five (5)
              candidates, in which case the procedures set forth in
              subparagraphs 2(a) - 2(d) shall be repeated.

3.     No earlier than twenty-eight (28) days or later than fifty-six (56) days
       after selection, the neutral shall hold a hearing to resolve each of the
       issues identified by the parties. The ADR proceeding shall take place at
       a location agreed upon by the parties. If the parties cannot agree, the
       neutral shall designate a location other than the principal place of
       business of either party or any of their subsidiaries or affiliates.
<PAGE>

4.     At least seven (7) days prior to the hearing, each party shall submit the
       following to the other party and the neutral:

       (a)    a copy of all exhibits on which such party intends to rely in any
              oral or written presentation to the neutral;

       (b)    a list of any witnesses such party intends to call at the hearing,
              and a short summary of the anticipated testimony of each witness;

       (c)    a proposed ruling on each issue to be resolved, together with a
              request for a specific damage award or other remedy for each
              issue. The proposed rulings and remedies shall not contain any
              recitation of the facts or any legal arguments and shall not
              exceed one (1) page per issue.

       (d)    a brief in support of such party's proposed rulings and remedies,
              provided that the brief shall not exceed twenty (20) pages. This
              page limitation shall apply regardless of the number of issues
              raised in the ADR proceeding.

       Except as expressly set forth in subparagraphs 4(a) - 4(d), no discovery
       shall be required or permitted by any means, including depositions,
       interrogatories, requests for admissions, or production of documents.

5.     The hearing shall be conducted on two (2) consecutive days and shall be
       governed by the following rules:


       (a)    Each party shall be entitled to five (5) hours of hearing time to
              present its case. The neutral shall determine whether each party
              has had the five (5) hours to which it is entitled.
<PAGE>

       (b)    Each party shall be entitled, but not required, to make an opening
              statement, to present regular and rebuttal testimony, documents or
              other evidence, to cross-examine witnesses, and to make a closing
              argument. Cross-examination of witnesses shall occur immediately
              after their direct testimony, and cross-examination time shall be
              charged against the party conducting the cross-examination.

       (c)    The party initiating the ADR shall begin the hearing and, if it
              chooses to make an opening statement, shall address not only
              issues it raised but also any issues raised by the responding
              party. The responding party, if it chooses to make an opening
              statement, also shall address all issues raised in the ADR.
              Thereafter, the presentation of regular and rebuttal testimony and
              documents, other evidence, and closing arguments shall proceed in
              the same sequence.

       (d)    Except when testifying, witnesses shall be excluded from the
              hearing until closing arguments.

       (e)    Settlement negotiations, including any statements made therein,
              shall not be admissible under any circumstances. Affidavits
              prepared for purposes of the ADR hearing also shall not be
              admissible. As to all other matters, the neutral shall have sole
              discretion regarding the admissibility of any evidence.

6.     Within seven (7) days following completion of the hearing, each party may
       submit to the other party and the neutral a post-hearing brief in support
       of its proposed rulings and remedies, provided that such brief shall not
       contain or discuss any new evidence and shall not exceed ten (10) pages.
       This page limitation shall apply regardless of the number of issues
       raised in the ADR proceeding.

7.     The neutral shall rule on each disputed issue within fourteen (14) days
       following completion of the hearing. Such ruling shall adopt in its
       entirety the proposed ruling and remedy of one of the parties on each
       disputed issue but may adopt one party's proposed rulings and remedies on
       some
<PAGE>

       issues and the other party's proposed rulings and remedies on other
       issues. The neutral shall not issue any written opinion or otherwise
       explain the basis of the ruling.

8.     The neutral shall be paid a reasonable fee plus expenses. These fees and
       expenses, along with the reasonable legal fees and expenses of the
       prevailing party (including all expert witness fees and expenses), the
       fees and expenses of a court reporter, and any expenses for a hearing
       room, shall be paid as follows:

       (a) If the neutral rules in favor of one party on all disputed issues in
           the ADR, the losing party shall pay 100% of such fees and expenses.

       (b) If the neutral rules in favor of one party on some issues and the
           other party on other issues, the neutral shall issue with the rulings
           a written determination as to how such fees and expenses shall be
           allocated between the parties. The neutral shall allocate fees and
           expenses in a way that bears a reasonable relationship to the outcome
           of the ADR, with the party prevailing on more issues, or on issues of
           greater value or gravity, recovering a relatively larger share of its
           legal fees and expenses.

9.     The rulings of the neutral and the allocation of fees and expenses shall
       be binding, non-reviewable, and non-appealable, and may be entered as a
       final judgment in any court having jurisdiction.

10.    Except as provided in paragraph 9 or as required by law, the existence of
       the dispute, any settlement negotiations, the ADR hearing, any
       submissions (including exhibits, testimony, proposed rulings, and
       briefs), and the rulings shall be deemed Confidential Information. The
       neutral shall have the authority to impose sanctions for unauthorized
       disclosure of Confidential Information.

11.    All disputes referred to ADR, the statute of limitations, and the
       remedies for any wrong that may be found, shall be governed by the laws
       of the State of Illinois.
<PAGE>

12.    The neutral may not award punitive damages. The parties hereby waive the
       right to punitive damages.

13.    The hearings shall be conducted in the English language.

14.    The parties shall not have ex parte communications with the neutral
       during the pendancy of the ADR proceeding before such neutral.

                                   Exhibit B

                        Alternative Dispute Resolution
                        ------------------------------

The parties recognize that bona fide disputes as to certain matters may arise
from time to time during the term of this Agreement which relate to either
party's rights and/or obligations. To have such a dispute resolved by this
Alternative Dispute Resolution ("ADR") provision, a party first must send
written notice of the dispute to the other party for attempted resolution by
good faith negotiations between their respective presidents (or their
equivalents) of the affected subsidiaries, divisions, or business units within
twenty-eight (28) days after such notice is received (all references to "days"
in this ADR provision are to calendar days).

If the matter has not been resolved within twenty-eight (28) days of the notice
of dispute, or if the parties fail to meet within such twenty-eight (28) days,
either party may initiate an ADR proceeding as provided herein. The parties
shall have the right to be represented by counsel in such a proceeding.

1.   To begin an ADR proceeding, a party shall provide written notice to the
     other party of the issues to be resolved by ADR. Within fourteen (14) days
     after its receipt of such notice, the other party may, by written notice to
     the party initiating the ADR, add additional issues to be resolved within
     the same ADR.

2.   Within twenty-one (21) days following receipt of the original ADR notice,
     the parties shall select a mutually acceptable neutral to preside in the
     resolution of any disputes in this ADR proceeding. If the parties are
     unable to agree on a mutually acceptable neutral within such period, either
     party may request the President of the CPR Institute for Dispute Resolution
     ("CPR"), 366 Madison Avenue, 14th Floor, New York, New York 10017, to
     select a neutral pursuant to the following procedures:

<PAGE>

     (a)  The CPR shall submit to the parties a list of not less than five (5)
          candidates within fourteen (14) days after receipt of the request,
          along with a Curriculum Vitae for each candidate. No candidate shall
          be an employee, director, or shareholder of either party or any of
          their subsidiaries or affiliates.

     (b)  Such list shall include a statement of disclosure by each candidate of
          any circumstances likely to affect his or her impartiality.

     (c)  Each party shall number the candidates in order of preference (with
          the number one (1) signifying the greatest preference) and shall
          deliver the list to the CPR within seven (7) days following receipt of
          the list of candidates. If a party believes a conflict of interest
          exists regarding any of the candidates, that party shall provide a
          written explanation of the conflict to the CPR along with its list
          showing its order of preference for the candidates. Any party failing
          to return a list of preferences on time shall be deemed to have no
          order of preference.

     (d)  If the parties collectively have identified fewer than three (3)
          candidates deemed to have conflicts, the CPR immediately shall
          designate as the neutral the candidate for whom the parties
          collectively have indicated the greatest preference. If a tie should
          result between two candidates, the CPR may designate either candidate.
          If the parties collectively have identified three (3) or more
          candidates deemed to have conflicts, the CPR shall review the
          explanations regarding conflicts and, in its sole discretion, may
          either (i) immediately designate as the neutral the candidate for whom
          the parties collectively have indicated the greatest preference, or
          (ii) issue a new list of not less than five (5) candidates, in which
          case the procedures set forth in subparagraphs 2(a) - 2(d) shall be
          repeated.

3.   No earlier than twenty-eight (28) days or later than fifty-six (56) days
     after selection, the neutral shall hold a hearing to resolve each of the
     issues identified by the parties. The ADR proceeding shall take place at a
     location agreed upon by the parties. If the parties cannot

<PAGE>

     agree, the neutral shall designate a location other than the principal
     place of business of either party or any of their subsidiaries or
     affiliates.

4.   At least seven (7) days prior to the hearing, each party shall submit the
     following to the other party and the neutral:

     (a)  a copy of all exhibits on which such party intends to rely in any oral
          or written presentation to the neutral;

     (b)  a list of any witnesses such party intends to call at the hearing, and
          a short summary of the anticipated testimony of each witness;

     (c)  a proposed ruling on each issue to be resolved, together with a
          request for a specific damage award or other remedy for each issue.
          The proposed rulings and remedies shall not contain any recitation of
          the facts or any legal arguments and shall not exceed one (1) page per
          issue.

     (d)  a brief in support of such party's proposed rulings and remedies,
          provided that the brief shall not exceed twenty (20) pages. This page
          limitation shall apply regardless of the number of issues raised in
          the ADR proceeding.

     Except as expressly set forth in subparagraphs 4(a) - 4(d), no discovery
     shall be required or permitted by any means, including depositions,
     interrogatories, requests for admissions, or production of documents.

5.   The hearing shall be conducted on two (2) consecutive days and shall be
     governed by the following rules:

<PAGE>

     (a)  Each party shall be entitled to five (5) hours of hearing time to
          present its case. The neutral shall determine whether each party has
          had the five (5) hours to which it is entitled.

     (b)  Each party shall be entitled, but not required, to make an opening
          statement, to present regular and rebuttal testimony, documents or
          other evidence, to cross-examine witnesses, and to make a closing
          argument. Cross-examination of witnesses shall occur immediately after
          their direct testimony, and cross-examination time shall be charged
          against the party conducting the cross-examination.

     (c)  The party initiating the ADR shall begin the hearing and, if it
          chooses to make an opening statement, shall address not only issues it
          raised but also any issues raised by the responding party. The
          responding party, if it chooses to make an opening statement, also
          shall address all issues raised in the ADR. Thereafter, the
          presentation of regular and rebuttal testimony and documents, other
          evidence, and closing arguments shall proceed in the same sequence.

     (d)  Except when testifying, witnesses shall be excluded from the hearing
          until closing arguments.

     (e)  Settlement negotiations, including any statements made therein, shall
          not be admissible under any circumstances. Affidavits prepared for
          purposes of the ADR hearing also shall not be admissible. As to all
          other matters, the neutral shall have sole discretion regarding the
          admissibility of any evidence.

6.   Within seven (7) days following completion of the hearing, each party may
     submit to the other party and the neutral a post-hearing brief in support
     of its proposed rulings and remedies, provided that such brief shall not
     contain or discuss any new evidence and shall not exceed ten (10) pages.
     This page limitation shall apply regardless of the number of issues raised
     in the ADR proceeding.

<PAGE>

7.   The neutral shall rule on each disputed issue within fourteen (14) days
     following completion of the hearing. Such ruling shall adopt in its
     entirety the proposed ruling and remedy of one of the parties on each
     disputed issue but may adopt one party's proposed rulings and remedies on
     some issues and the other party's proposed rulings and remedies on other
     issues. The neutral shall not issue any written opinion or otherwise
     explain the basis of the ruling.

8.   The neutral shall be paid a reasonable fee plus expenses. These fees and
     expenses, along with the reasonable legal fees and expenses of the
     prevailing party (including all expert witness fees and expenses), the fees
     and expenses of a court reporter, and any expenses for a hearing room,
     shall be paid as follows:

     (a)  If the neutral rules in favor of one party on all disputed issues in
          the ADR, the losing party shall pay 100% of such fees and expenses.

     (b)  If the neutral rules in favor of one party on some issues and the
          other party on other issues, the neutral shall issue with the rulings
          a written determination as to how such fees and expenses shall be
          allocated between the parties. The neutral shall allocate fees and
          expenses in a way that bears a reasonable relationship to the outcome
          of the ADR, with the party prevailing on more issues, or on issues of
          greater value or gravity, recovering a relatively larger share of its
          legal fees and expenses.

9.   The rulings of the neutral and the allocation of fees and expenses shall be
     binding, non-reviewable, and non-appealable, and may be entered as a final
     judgment in any court having jurisdiction.

10.  Except as provided in paragraph 9 or as required by law, the existence of
     the dispute, any settlement negotiations, the ADR hearing, any submissions
     (including exhibits, testimony, proposed rulings, and briefs), and the
     rulings shall be deemed Confidential Information. The neutral shall have
     the authority to impose sanctions for unauthorized disclosure of
     Confidential Information.

<PAGE>

11.  All disputes referred to ADR, the statute of limitations, and the remedies
     for any wrong that may be found, shall be governed by the laws of the State
     of Illinois.

12.  The neutral may not award punitive damages. The parties hereby waive the
     right to punitive damages.

13.  The hearings shall be conducted in the English language.

14.  The parties shall not have ex parte communications with the neutral during
     the pendancy of the ADR proceeding before such neutral.
