                                 CONFIDENTIALITY

     SECTION 7.01. CONFIDENTIALITY; EXCEPTIONS. Except to the extent expressly
authorized by this Agreement or otherwise agreed in writing, the Parties agree
that the receiving Party shall keep confidential and shall not publish or
otherwise disclose or use for any purpose other than as provided for in this
Agreement any Information and other information and materials furnished to it by
the other Party pursuant to this Agreement or any Information developed during
the course of the collaboration hereunder, or any provisions of this Agreement
that are the subject of an effective order of the United States Securities
Exchange Commission granting confidential treatment pursuant to the United
States Securities Act of 1934, as amended (collectively, "CONFIDENTIAL
INFORMATION"), except to the extent that it can be established by the receiving
Party that such Confidential Information:

     (a)  was already known to the receiving Party, other than under an
obligation of confidentiality, at the time of disclosure by the other Party;

     (b)  was generally available to the public or otherwise part of the public
domain at the time of its disclosure to the receiving Party;

     (c)  became generally available to the public or otherwise part of the
public domain after its disclosure and other than through any act or omission of
the receiving Party in breach of this Agreement;

     (d)  was disclosed to the receiving Party, other than under an obligation
of confidentiality, by a Third Party who had no obligation to the disclosing
Party not to disclose such information to others; or

     (e)  was independently discovered and/or developed by the receiving Party
as documented in its corporate records.

     SECTION 7.02. AUTHORIZED DISCLOSURE. Each Party may disclose Confidential
Information hereunder to the extent such disclosure is reasonably necessary in
filing or prosecuting patent applications, prosecuting or defending litigation,
filing or updating any Drug Approval Application, complying with applicable
governmental regulations or conducting pre-clinical or clinical trials,
provided that if a Party is required by law or regulation to make any such
disclosures of the other Party's Confidential Information it will, except where
impracticable for necessary disclosures, for example in the event of medical
emergency, give reasonable advance notice to the other Party of such disclosure
requirement and, except to the extent inappropriate in the case of patent
applications, will use its reasonable efforts to secure confidential treatment
of such Confidential Information required to be disclosed. In addition,

                                       20
<Page>

and with prior notice to the other Party of each Third Party with whom a
confidential disclosure agreement is being entered into, each Party shall be
entitled to disclose, under a binder of confidentiality, Confidential
Information to any Third Party for the purpose of carrying out the purposes of
this Agreement. Nothing in this Article VII shall restrict any Party from using
for any purpose any Confidential Information independently developed by it
during the course of the collaboration hereunder, or from using Confidential
Information that is specifically derived from pre-clinical or clinical trials to
carry out Regulatory Approval, marketing, sales or professional services support
functions as is customary in the pharmaceutical industry.

     SECTION 7.03. SURVIVAL. This Article VII shall survive the termination or
expiration of this Agreement.

     SECTION 7.04. TERMINATION OF PRIOR AGREEMENT. This Agreement supersedes
the Secrecy Agreement between Alliance and Schering dated as of January 14,
1997. All Information exchanged between the Parties under that Agreement shall
be deemed Confidential Information and shall be subject to the terms of this
Article VII.

     SECTION 7.05. PUBLICATIONS. Prior to the launch of a Product, Alliance will
determine the overall strategy for publication in support of such Product.
Notwithstanding any term of Section 7.06 below, the Parties recognize the need
for scientific publications pertaining to development of the Product and the
Parties will cooperate to provide for such publications; provided, however, that
the right of any Party to withhold or delay consent to publish or delay
publication shall be subject to any contractual publication rights of Third
Parties involved in research or clinical trials for the Product. The Parties
will use reasonable efforts to obtain the voluntary consent of any Third Party
granted publication rights related to the Product prior to the Effective Date to
comply with reasonable notice and timing requests and will promptly review any
publications delivered for review.

     SECTION 7.06. PUBLICITY REVIEW. Subject to the further provisions of this
Section 7.06 and Section 10.04, no Party shall originate any written publicity,
news release, or other announcement or statement relating to this Agreement or
to performance hereunder or the existence of an arrangement between the Parties
(collectively, "WRITTEN DISCLOSURE"), without the prior prompt review and
written approval of the other, which approval shall not be unreasonably withheld
or delayed. Notwithstanding the foregoing provisions of this Section 7.06, any
Party may make any public Written Disclosure it believes in good faith based
upon the advice of counsel is required by applicable law or any listing or
trading agreement concerning its publicly traded securities, provided that prior
to making such Written Disclosure, the disclosing Party shall provide the other
Party with a copy of the materials proposed to be disclosed and provide the
receiving Party with an opportunity to promptly review the proposed Written
Disclosure. To the extent that the receiving Party reasonably requests that any
information in the materials proposed to be disclosed be deleted, the disclosing
Party shall request confidential treatment of such information pursuant to Rule
406 of the United States Securities Act of 1933 or Rule 26b-2 of the United
States Securities Exchange Act of 1934, as applicable (or any other applicable
regulation relating to the confidential treatment of information), so that there
be omitted from the materials that are publicly filed any information that the
receiving Party reasonably requests to

                                       21
<Page>

be deleted. The terms of this Agreement may also be disclosed to (i) government
agencies where required by law, or (ii) Third Parties with the prior written
consent of the other Party, which consent shall not be unreasonably withheld or
delayed, so long as such disclosure is made under a binder of confidentiality
and so long as highly sensitive terms and conditions such as financial terms are
extracted from the Agreement or not disclosed upon the request of the other
Party. All Written Disclosures shall be factual and as brief as is reasonable
under the circumstances. Upon request by either Party, the Parties agree to
prepare a mutually agreed press release and question and answer document with
respect to this Agreement. Each Party agrees that it will use reasonable efforts
to cause all Written Disclosures and oral statements relating hereto to be
consistent with the answers specified in such question and answer document.

                                  ARTICLE VIII

any inventions made solely by that Party's employees or consultants in the
course of performing work under this Agreement.

     SECTION 8.02. PATENT FILINGS. Each Party, at its sole discretion and
responsibility, shall prepare, file, prosecute and maintain Patents to cover

discovered, and which relates to the subject matter of this Agreement.

     SECTION 8.04. ENFORCEMENT RIGHTS.

     (a)  NOTIFICATION OF INFRINGEMENT. If either Party learns of any
infringement or threatened infringement by a Third Party of the Alliance
Patents, such Party shall promptly notify the other Party and shall provide such
other Party with all available evidence of such infringement.

     (b)  ENFORCEMENT IN THE TERRITORY. Alliance shall have the right, but not
the obligation, to institute, prosecute and control at its own expense any
action or proceeding with respect to infringement of any Alliance Patents
covering the manufacture, use, importation, sale or offer for sale of the
product being developed or marketed by counsel of its own choice. Where possible
with regard to manpower and time, Schering upon Alliance's request and at
Alliance's costs, shall give documentary support and reasonable assistance in
such proceedings. Any damages or other monetary awards recovered pursuant to
this Section 8.04(b) shall be for the account of Alliance. If Alliance fails or
does not want to bring an action or proceeding or otherwise take appropriate
action to abate such infringement within a period of one hundred eighty (180)
days of notice by Schering to Alliance requesting such action, Schering shall
have the right, but not the obligation, to institute, prosecute and control at
its own expense any such

                                       22

action or proceeding with respect to infringement of any Alliance patents.*


     (c)  SETTLEMENT WITH A THIRD PARTY. Alliance shall also have the right to
control settlement of such action; provided, however, that no settlement shall
be entered into without the written consent of the Schering (which consent shall
not be unreasonably withheld) if such settlement would materially and adversely
affect the interests of Schering.

     SECTION 8.05. DEFENSE AND SETTLEMENT OF THIRD PARTY CLAIMS. If a Third
Party asserts that a patent, trademark or other intangible right owned by it is
infringed by any Product, Alliance will be solely responsible for defending
against any such assertions at its cost and expense (subject to the provisions
of Section 8.04(b)). Any determination regarding the necessity to license or
otherwise obtain rights under or invalidate certain Third Party Patents covering
the Product shall be made by Alliance; provided, however, that no settlement may
be entered into without the written consent of Schering (which shall not be
unreasonably withheld) if such settlement would materially and adversely affect
the interests of Schering.*


     SECTION 8.06. PATENT EXPENSES. All worldwide Patent Expenses shall be
borne by Alliance, subject to the terms of this Agreement.

     SECTION 8.07. TRADEMARKS.

     (a)  SCHERING. Schering shall be responsible for the selection,

connection therewith). Alliance recognizes the exclusive ownership by Schering
of any proprietary Schering name, logotype or trademark furnished by Schering
(including Schering's Affiliates) for use in connection with the Product.
Alliance shall not, either while this Agreement is in effect, or at any time
thereafter, register, use or attempt to obtain any right in or to any such name,
logotype or trademark or in and to any name, logotype or trademark confusingly
similar thereto.

     (b)  ALLIANCE.  Schering hereby reconveys to Alliance all rights to the
trademark for "Imagent" granted pursuant to the Original License Agreement.

<Page>

          (i)   This Agreement is a legal and valid obligation binding upon such
  Party and enforceable in accordance with its terms. The execution, delivery
  and performance of the Agreement by such Party does not conflict with any
  agreement, instrument or understanding, oral or written, to which it is a
  party or by which it is bound, nor violate any law or regulation of any court,
  governmental body or administrative or other agency having jurisdiction over
  it.

          (ii)  Alliance has not, and during the term of the Agreement neither
  Party will, (x) grant any right to any Third Party relating to the Alliance
  Patents and to Alliance Know-How in the Field which would conflict with the
  rights granted to either Party hereunder, and (y) to the best of its knowledge
  neither party is employing (as an employee or consultant), nor will either
  Party employ during the term of this Agreement, any person that has been
  debarred by the FDA.

          (iii) To the best of its knowledge Alliance is not obligated under any
  agreement as of the Effective Date and the Restatement Date to pay any Third
  Party royalties with respect to the Product. As of the Effective Date and the
  Restatement Date there are no such agreements in place.

     (b)  Alliance hereby represents and warrants to Schering as follows:

          (i)   It has given Schering access to all its pre-clinical and
  clinical records regarding the Product in existence as of the Effective Date
  and the Restatement Date.

          (ii)  As of the Effective Date and the Restatement Date, except as it
  may have previously disclosed to Schering in writing or otherwise, it has not

     SECTION 9.02. PERFORMANCE BY AFFILIATES. The Parties recognize that each
Party may perform some or all of its obligations under this Agreement through
Affiliates; provided, however, that each Party shall remain responsible for and
be a guarantor of the performance by its Affiliates and shall cause its
Affiliates to comply with the provisions of this Agreement in connection with
such performance.

                                    ARTICLE X
                             INFORMATION AND REPORTS

     SECTION 10.01. INFORMATION AND REPORTS DURING DEVELOPMENT AND
COMMERCIALIZATION. Schering and Alliance will disclose and make available
(subject to any confidentiality agreements or requirements of law) to each other
without charge all preclinical, clinical, regulatory, pricing, sales and other
Information, including copies of all preclinical and clinical reports, known by
Schering or Alliance directly concerning the Product within the Field at any
time during the term of this Agreement. Each Party shall own and maintain its
own database of clinical trial data accumulated from all clinical trials of the
Product for which it was

                                       24
<Page>

responsible and of adverse drug event information for the Product. At the option
of the requesting Party, such data shall be provided in a computer readable
format by the providing Party, to the extent available, which shall also assist
in the transfer and validation of such data to the receiving Party. Without
limitation of the foregoing, each Party shall supply to the other the
Information required by the other Party and requested by it (either as a routine
practice or as a specific request) for purposes of compliance with regulatory
requirements.

     SECTION 10.02. ADVERSE DRUG EXPERIENCES.

     (a)  Alliance agrees to provide to Schering for initial and/or periodic
submission to government agencies significant information on the Product from
preclinical laboratory, animal toxicology and pharmacology studies, as well as
adverse drug experience reports from clinical trials and commercial experiences
with the Product;

     (b)  Each party agrees to, in connection with investigational Products,
report to the other party as soon as possible (and, in any event, within three
(3) days) the receipt of a report of any unexpected or serious experience, if
required for the other Party to comply with regulatory requirements;

     (c)  Each Party agrees to, in connection with marketed Products, report to
the other Party within three (3) business days of the receipt of a report of any
adverse experience that is serious and unexpected or sooner if required for the
other Party to comply with regulatory requirements. Serious adverse experience
means any experience that suggests a significant hazard, contraindication, side
effect or precaution, or any experience that is fatal or life threatening, is
permanently disabling, requires or prolongs inpatient hospitalization, or is a
congenital anomaly, cancer, or overdose. An unexpected adverse experience is one
not identified in nature, specificity, severity or frequency in the current
investigator brochure or the U.S. labeling for the drug; and

     (d)  If requested by Schering, Alliance agrees to enter into a standard
operating procedure by and between the Parties to govern the exchange of
information relating to adverse drug experiences and product quality.

     SECTION 10.03. RECORDS OF REVENUES AND EXPENSES.

     (a)  Each Party will maintain complete and accurate records which are
relevant to revenues, costs, expenses and payments on a country-by-country basis
under this Agreement and such records shall be open during reasonable business
hours for a period of two (2) years from creation of individual records for
examination at the other Party's expense and not more often than once each year
by a certified public accountant selected by the other Party, or the other
Party's internal accountants unless the first Party objects to the use of such
internal accountants, for the sole purpose of verifying for the inspecting Party
the correctness of calculations and classifications of such revenues, costs,
expenses or payments made under this Agreement. Each party shall bear its own
costs related to such audit; provided, however, that, for any underpayments by a
Party greater than five percent (5%), such Party shall pay the other Party the
amount of underpayment, interest as provided for in Section 5.04(b) from the
time the

                                       25
<Page>

amount was due and the other Party's out-of-pocket expenses. For any
underpayments less than five percent (5%) by a Party found under this Section,
such Party shall pay the other Party the amount of underpayment. Any
overpayments by a Party will be refunded to such Party or credited to future
royalties, at such Party's election. Any records or accounting information
received from the other Party shall be Confidential Information for purposes of
Article VII. Results of any such audit shall be provided to both Parties,
subject to Article VII.

     (b)  If there is a dispute between the Parties following any audit
performed pursuant to Section 10.03(a), either party may refer the issue (an
"AUDIT DISAGREEMENT") to an independent certified public accountant for
resolution. In the event an Audit Disagreement is submitted for resolution by
either Party, the Parties shall comply with the following procedures:

          (i)   The Party submitting the Audit Disagreement for resolution shall
  provide written notice to the other Party that it is invoking the procedures
  of this Section 10.03(b).

          (ii)  Within thirty (30) business days of the giving of such notice,
  the Parties shall jointly select a recognized international accounting firm to
  act as an independent expert to resolve such Audit Disagreement.

          (iii) The Audit Disagreement submitted for resolution shall be
  described by the Parties to the independent expert, which description may be
  in written or oral form, within ten (10) business days of the selection of
  such independent expert.

          (iv)  The independent expert shall render a decision on the matter as
  soon as practicable.

          (v)   The decision of the independent expert shall be final and
  binding unless such Audit Disagreement involves alleged fraud, breach of this
  Agreement or construction or interpretation of any of the terms and conditions
  hereof.

          (vi)  All fees and expenses of the independent expert, including any
  third party support staff or other costs incurred with respect to carrying out
  the procedures specified at the direction of the independent expert in
  connection with such Audit Disagreement, shall be borne by the Party that did
  not submit the Audit Disagreement in the event that a discrepancy of more than
  two percent (2%) results from such decision, and by each Party in inverse
  proportion to the disputed amounts awarded to the Party by the independent
  expert through such decision (e.g. Alliance disputes $100, the independent
  expert awards Alliance $50, then each party pays one-half (1/2) of the
  independent expert's costs) in all other cases.

     SECTION 10.04. APPLICABILITY. This Article X shall be applicable following
the Restatement Date (without prejudice to any rights accruing prior to the
Restatement Date) only if Schering undertakes Development or Commercialization
activities with regard to a Product following the Restatement Date or exercises
its option under Section 4.01(d).

                              TERM AND TERMINATION

     SECTION 11.01. TERM. This Agreement shall commence as of the Effective Date
and, unless sooner terminated as provided herein shall continue in effect until
no royalties or other payments are payable hereunder to either Alliance or
Schering.

     SECTION 11.02. TERMINATION.

     (a)  Notwithstanding any other provision herein, Schering may, prior to
Regulatory Approval of a Product, terminate this Agreement on a country by
country basis or in its entirety upon one (1) month written notice to Alliance.
After receipt of Regulatory Approval of a Product and prior to the First
Commercial Sale of said Product in the applicable country, Schering may
terminate this Agreement on a country by country basis upon two (2) months
written notice to Alliance. After the First Commercial Sale of a Product,
Schering may terminate this Agreement on a country by country basis upon three
(3) months written notice to Alliance.

     (b)  Failure by Schering or Alliance to comply with any of the respective
material obligations and conditions contained in this Agreement shall entitle
the other Party to give the Party in default notice requiring it to cure such
default. If such default is not cured within ninety (90) days after receipt of
such notice, the notifying Party shall be entitled (without prejudice to any of
its other rights conferred on it by this Agreement) to terminate this Agreement
or in the event of an uncured material breach by Alliance, effect the rights of
Schering set forth in Section 11.02(e) by giving a notice to take effect
immediately. Notwithstanding the foregoing, in the event of a non-monetary
default, if the default is not reasonably capable of being cured within the
ninety (90) day cure period by the defaulting Party and such defaulting Party is
making a good faith effort to cure such default, the notifying Party may not
terminate this Agreement, provided however, that the notifying Party may
terminate this Agreement if such default is not cured within one hundred eighty
(180) days of such original notice of default. The right of either Party to
terminate this Agreement as hereinabove provided shall not be affected in any
way by its waiver of, or failure to take action with respect to any previous
default.

     (c)  In the event that one of the Parties hereto shall go into liquidation,
a receiver or a trustee be appointed for the property or estate of that Party
and said receiver or trustee is not removed within sixty (60) days, or the Party
makes an assignment for the benefit of creditors (collectively, a "BANKRUPTCY
EVENT"), and whether any of the aforesaid Bankruptcy Events be the outcome of
the voluntary act of that Party, or otherwise, the other Party shall be entitled
to terminate this Agreement (or in the event Alliance suffers such a Bankruptcy
Event, Schering may effect its rights described in Section 11.02(e) forthwith by
giving a written notice to Alliance.

     (d)  In the event that this Agreement is terminated by Schering in one or
more countries or in its entirety, and in the event that the Agreement is
terminated by either Party in its entirety in accordance with Sections 11.02(a),
(b) or (c) hereof, Schering will with respect to each country for which the
termination applies entirely:

                                       27
<Page>

          (i)   deliver to Alliance the Alliance Know-How and assign to Alliance
  its rights in said Alliance Know-How and Alliance Patents if any, in either
  case relating solely to the country that is the subject of the termination;

          (ii)  not use the Alliance Know-How as long as it has to be kept
  confidential pursuant to Article VII hereof in such country;

          (iii) not infringe any of the Alliance Patents in such country;

          (iv)  make all payments accrued under this Agreement with respect to
  such country prior to the effective termination date;

          (v)   transfer all regulatory filings and approvals related to the
  Product in such country to Alliance upon Alliance's written request for same;

          (vi)  transfer to Alliance responsibility for and control of ongoing
  work of Schering related to the Product, Affiliates and Third Parties in an
  expeditious and orderly manner with the costs for such work assumed by
  Alliance as of the date of notice; and

          (vii) sell to Alliance, at any time within ninety (90) days of such
  termination, at Alliance's election, all or any portion of the inventory of
  the Product owned by Schering or its Affiliates which are intended for sale in
  such country at a price equal to Schering's or its Affiliate's cost for such
  inventory. Such election shall be made by Alliance in writing and within
  thirty (30) days of such election, Schering shall ship at Alliance's cost and
  direction such inventory to Alliance. Alliance shall pay for such inventory
  within forty-five (45) days of receipt of such inventory.

     (e)  In the event of a Bankruptcy Event or a material default described in
Sections 11.02(b) and (c) by Alliance (which default is not cured as provided
therein), Schering may elect in lieu of terminating this Agreement to declare
the license granted pursuant to this Agreement to be irrevocable. From the date
of receipt of notice of such election, Alliance shall have no further rights or
obligations under this Agreement, except that Alliance may enforce any financial
obligations of Schering, including those arising under Article V herein before
or after such election, and Schering may enforce any manufacturing and supply
obligations of Alliance, including those arising under Section 11.02(f);
provided, however, that if such election occurs prior to the First Commercial
Sale of the Product, any additional Development Expenses and reasonable costs
incurred by Schering to Commercialize the Product as a result of such election
shall be credited against amounts payable by Schering to Alliance.

     (f)  In the event of termination of this Agreement pursuant to this Section
11.02 where the Party terminating this Agreement is the Manufacturing Party, the
Manufacturing Party shall continue to provide for manufacture of the Product to
the extent provided prior to notice of such termination, from the effective date
of such termination until such time as the Non-Manufacturing Party is able to
secure an equivalent alternative commercial manufacturing source, as requested
by the Non-Manufacturing Party.

                                       28
<Page>

     (g)  Except where expressly provided for otherwise in this Agreement,
termination of this Agreement shall not relieve the Parties hereto of any
liability, including any obligation to make payments hereunder, which accrued
hereunder prior to the effective date of such termination, nor preclude any
Party from pursuing all rights and remedies it may have hereunder or at law or
in equity with respect to any breach of this Agreement nor prejudice any Party's
right to obtain performance of any obligation.

     SECTION 11.03. SURVIVING RIGHTS. The rights and obligations set forth in
this Agreement shall extend beyond the term or termination of the Agreement only
to the extent expressly provided for herein, or the extent that the survival of
such rights or obligations are necessary to permit their complete fulfillment or

                                 INDEMNIFICATION

     SECTION 12.01. INDEMNIFICATION. With respect to the Product (determined on
a country by country basis):

     (a)  Schering and Alliance hereby agree to save, defend and hold the other
Party and its agents and employees harmless from and against any and all suits,
claims, actions, demands, liabilities, expenses and/or losses, including
reasonable legal expenses and attorneys' fees (collectively, "LOSSES") resulting
directly from the Development or Commercialization of the Product to the extent
such Development or Commercialization was performed by such Party except to the
extent such Losses result from the negligence or willful misconduct of the other
Party, in which case such Party hereby agrees to save, defend and hold the other
Party and its agents and employees harmless from any and all such Losses.

     (b)  Each indemnified Party agrees to give the indemnifying Party prompt
written notice of any Loss or discovery of fact upon which such indemnified
Party intends to base a request for indemnification under Sections 12.01(a).
Each Party shall furnish promptly to the other copies of all papers and official
documents received in respect of any Loss. With respect to any Loss relating
solely to the payment of money damages and which will not result in the
indemnified Party becoming subject to injunctive or other relief or otherwise
adversely affecting the business of the indemnified Party in any 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 Loss,
on such terms as the indemnifying Party, in its sole discretion, shall deem
appropriate. The indemnifying Party shall obtain the written consent of the
indemnified Party, which shall not be unreasonably withheld or delayed, prior to
ceasing to defend, settling or otherwise disposing of any Loss if as a result
thereof the indemnified Party would become subject to injunctive or other
equitable relief or any remedy other than the payment of money, which payment
would be the responsibility of the indemnifying Party. The indemnifying Party
shall not be liable for any settlement or other disposition of a Loss by the
indemnified Party which is reached without the written consent of the
indemnifying Party. The reasonable costs and expenses, including reasonable fees
and disbursements of counsel incurred by any

                                       29

indemnified Party in connection with any Loss, shall be reimbursed on a
quarterly basis by the indemnifying Party, without prejudice to the indemnifying
Party's right to contest the indemnified Party's right to indemnification and
subject to refund in the event the indemnifying party is ultimately held not to
be obligated to indemnify the indemnified Party.

                                  ARTICLE XIII
                                  MISCELLANEOUS

     SECTION 13.01. ASSIGNMENT.

     (a)  Schering may assign any of its rights or obligations under this
Agreement in any country to any of its Affiliates or to any sublicensee as
provided in Section 3.01; provided, however, that such assignment shall not
relieve Schering of its responsibilities for performance of its obligations
under this Agreement.

     (b)  Alliance may assign any of its rights or obligations under this
Agreement in any country to any of its Affiliates or to any sublicensee if
permitted by Section 3.02; provided, however, that such assignment shall not
relieve Alliance of its responsibilities for performance of its obligations
under this Agreement.

     (c)  Either Party may assign its rights or obligations under this Agreement
in connection with a merger or similar reorganization or the sale of all or
substantially all of its assets, or otherwise with the prior written consent of
the other Party. This Agreement shall survive any such merger or reorganization
of either Party with or into, or such sale of assets to, another Party and no
consent for such merger, reorganization or sale shall be required hereunder;
provided, that in the event of such merger, reorganization or sale, no
intellectual property rights of the acquiring corporation shall be included in
the technology licensed hereunder.

     (d)  This Agreement shall be binding upon and inure to the benefit of the
successors and permitted assigns of the Parties. Any assignment not in
accordance with this Agreement shall be void.

     SECTION 13.02. RETAINED RIGHTS. Nothing in this Agreement shall limit in
any respect the right of either Party to conduct research and development and to
market products using such Party's technology other than as herein expressly
provided.

     SECTION 13.03. FORCE MAJEURE. Neither Party shall lose any rights hereunder
or be liable to the other Party for damages or losses on account of failure of
performance by the defaulting Party if the failure is occasioned by government
action, war, fire, explosion, flood, strike, lockout, embargo, act of God, or
any other cause beyond the control of the defaulting Party, provided that the
Party claiming force majeure has extended all reasonable efforts to avoid or
remedy such force majeure, continues to employ such efforts and promptly
notifies the other Party of such force majeure event.

waiver from time to time by either of the Parties of any of their rights or

continuing waiver of same or any other of such Party's rights or remedies
provided in this Agreement.

     SECTION 13.08. SEVERABILITY. If any term, covenant or condition of this
Agreement or the application thereof to any Party or circumstances shall, to any

remainder of this Agreement, or the application of such term, covenant or
condition to Parties or circumstances other than those as to which it is held
invalid or unenforceable, shall not be affected thereby and each term, covenant
or condition of this Agreement shall be valid and be enforced to the fullest
extent permitted by law; and (ii) the Parties hereto covenant and agree to
renegotiate any such term, covenant or application thereof in good faith in
order to provide a reasonably acceptable alternative to the term, covenant or

unenforceable, it being the intent of the Parties that the basic purposes of
this Agreement are to be effectuated.

     SECTION 13.09. AMBIGUITIES. Ambiguities, if any, in this Agreement shall
not be construed against any Party, irrespective of which Party may be deemed to

     SECTION 13.13. ENTIRE AGREEMENT; AMENDMENTS. This Agreement, including all
Exhibits attached hereto and thereto, and all documents delivered concurrently
herewith and therewith, set forth all the covenants, promises, agreements,
warranties, representations, conditions and understandings between the Parties
hereto and supersede and terminate all prior agreements and understandings
between the Parties. There are no covenants, promises, agreements, warranties,
representations, conditions or understandings, either oral or written, between

alteration, amendment, change or addition to this Agreement shall be binding
upon the Parties hereto unless reduced to writing and signed by the respective
authorized officers of the Parties. This Agreement, including without limitation

extent of the legally enforceable undertakings of the Parties hereto,

                                       32
<Page>

and no promise or representation, written or oral, which is not set forth

shall it represent to any person that it has any such right or authority.
Nothing in this Agreement shall be construed as establishing a partnership or
joint venture relationship between the Parties.

     SECTION 13.16. USE OF NAMES. Neither Party shall use the name of the other

consent shall not be unreasonably withheld or delayed; provided, however, that
either Party may use the name of the other Party in any document filed with any
regulatory agency or authority, including the FDA and the Securities and
Exchange Commission, in which case Schering shall be referred to as "Schering

transaction in any press release, public announcement or other public document

                                    EXHIBIT A

                    DETERMINATION OF CERTAIN ACCOUNTING TERMS

     As a supplement to the definitions provided in Article I of the License
Agreement (this "AGREEMENT"), originally dated as of September 23, 1997, and
amended and restated in its entirety as of February 22, 2002 between ALLIANCE
PHARMACEUTICAL CORP. and SCHERING AKTIENGESELLSCHAFT, the following accounting
terms shall be further specified as follows, with the intent that the following
terms are to be interpreted in accordance with their reasonable and customary
meaning within the industry and consistently applied by a Party on a
company-wide basis:

  1. COST OF GOODS

     Cost of Goods shall be equal to the sum of Material Costs, Direct Labor
costs and Indirect Costs.

          A. "MATERIAL COSTS" shall mean the prices paid for raw material
  components and purchased finished goods, including any packaging necessary for
  the shipment of products, which are purchased from outside vendors as well as
  any freight and duty where applicable.

          B. "DIRECT LABOR COSTS" shall mean the labor hours required for an
  operation for such a Product multiplied by the direct labor rate for work
  centers within the relevant manufacturing operating unit (including salaries,
  wages and benefits).

          C. "INDIRECT COSTS" shall mean other costs associated with the
  operating unit(s) manufacturing a Product; provided, however, overhead
  attributable to unrelated facilities, or parts thereof, shall be excluded and
  that such Indirect Costs shall exclude costs associated with unused
  manufacturing capacity. Indirect Costs shall include expenses associated with
  quality assurance, manufacturing and engineering associated with the operating
  unit(s) manufacturing a Product and shall include straight line depreciation
  and property taxes specifically associated with the plant(s) manufacturing a
  Product.
