separately, and B is the total invoice price of the other active ingredient or

sold separately in said country, "Net Sales" shall be calculated by multiplying
actual Net Sales thereof by the fraction A/C where A is the invoice price of the
Product if sold separately, and C is the invoice price of the combination
product. If, on a country-by-country basis, the Product is not sold separately
in said country, "Net Sales" shall be determined by the Parties in good faith on
the basis of the fair market value of the Product. With respect to any transfer
of any Product in a given country for any substantive consideration other than
monetary consideration on arms length terms, for purposes of calculating "Net
Sales" under this Agreement, such Product shall be deemed to be sold exclusively

within ten (10) business days of receipt.

        (d)    Decision Making.    Actions to be taken by the JCC shall be taken
only following unanimous vote, with each Party having one (1) vote representing
the views of its members. If the JCC fails to reach unanimous agreement on a
matter before it for decision for a period in excess of [*] from the date first
presented to the JCC in writing, the matter shall be referred promptly to the
JSC for timely resolution.

        3.4   Joint Manufacturing Committee. A joint manufacturing committee
(the "Joint Manufacturing Committee" or "JMC") will be established pursuant to

strategic or commercially sensitive information beyond the scope of the
collaboration contemplated by this Agreement.

ARTICLE 4

PRODUCT DEVELOPMENT

        4.1   Overview. The Parties desire and intend to collaborate with
respect to the Development of the Product in the Field, as and to the extent set
forth in this Agreement. As described in more detail in this Article 4 (with
respect to the non-clinical and clinical aspects of Development) and Article 5
(with respect to the regulatory aspects of Development), the Parties have
already agreed that certain Development activities for the Product in the Field
will be jointly funded and others will be solely funded by Allos. The Parties
have also agreed upon a mechanism for proposing new studies in the Field and
determining whether the Parties wish to jointly fund such studies or if one of
the Parties may conduct such study without funding from the other Party.

Rule 24b-2 of the Securities Exchange Act of 1934, as amended.

        4.2   Development Plan.

        (a)    General.    Development of the Product with respect to the Field
shall be conducted pursuant to a comprehensive written development plan (the
"Development Plan"), which shall specify all Development activities for the
Product in the Field, regardless of whether such activities are jointly funded
by the Parties or funded by just one of the Parties, and shall include a
detailed timeline for performing those activities necessary to obtain Regulatory
Approval in the Field in each country in the Licensed Territory (such timeline,
the "Regulatory Plan"). For each Development activity specified in the
Development Plan, the Development Plan shall specify the Party that is
responsible for such activity, the timeline for initiating and completing such
activity, and the budget for such activity. For each clinical trial specified in
the Development Plan, the Development Plan shall specify the planned accrual for
such trial, the sites at which the trial will be conducted and the lead
investigator(s) for such trial.

        (b)    Initial Development Plan.    As of the Effective Date, the
Parties have agreed upon an initial Development Plan, which is set forth in the
Letter Agreement. The studies set forth in Exhibit 1 to the initial Development
Plan (the "Existing Studies") include: (i) studies that are being conducted by
or on behalf of Allos as of the Effective Date; (ii) activities that have not
been initiated as of the Effective Date but are needed to generate Information
that is required by the FDA as a condition of the Product's Regulatory Approval
in the U.S. for the Lead Indication; (iii) certain medical affairs, and clinical
and non-clinical studies that are identified in Exhibit 1 to the initial
Development Plan as "Allos Studies"; and (iv) those pediatric studies (and
associated preclinical and CMC requirements) required by the EMA with respect to
the Product in the Field (the "Pediatric Studies"). The initial Development Plan
identifies the Party with operational responsibility for the activities that
form a part of the Existing Studies. Allos shall be solely responsible for
timely conducting the Allos Studies and for all costs incurred in the course of
conducting the Allos Studies. The Parties shall share the costs of all other
Existing Studies as specified in Section 4.5.

        (c)    Amendments.    

        (i)    The JDC shall periodically (including at the specific times
specified in this Section 4.2(c)) review, and, as required, prepare an amendment
to the then-current Development Plan, for review, comment and approval by the
JSC. Such amended Development Plan shall reflect any changes (including
additions) to the Development of the Product in the Field. Once approved by the
JSC, the amended Development Plan shall become effective and supersede the
previous Development Plan as of the date of such approval.

        (ii)   Within [*] after the Effective Date, the JDC shall prepare and
submit to the JSC for its review, comment and approval, an amendment to the
Development Plan that adds the Regulatory Plan to the Development Plan.

        (iii) If EMA notifies either Party that any of the Pediatric Studies are
not required by the EMA with respect to the Product in the Field or takes other
action that results in any of the Pediatric Studies not being required by the
EMA with respect to the Product in the Field, the JDC shall promptly prepare and
submit to the JSC for its review, comment and

Rule 24b-2 of the Securities Exchange Act of 1934, as amended.

approval, an amendment to the Development Plan that removes such Pediatric
Studies from the Development Plan.

        (iv)  Promptly after the Parties agree to conduct an Additional Study
pursuant to Section 4.4(a) or 4.4(b), or a Party decides to proceed with an
Incremental Study pursuant to Section 4.4(c), the JDC shall prepare and submit
to the JSC for its review, comment and approval, an amendment to the Development
Plan that adds such Additional Study or Incremental Study to the Development
Plan.

        (v)   In addition to the foregoing, no later than June 30th of each
calendar year during the Term, starting with 2012, and more frequently at the
discretion of the JDC, the JDC shall determine if an amendment is needed to the
then-current Development Plan and, if appropriate, shall prepare and submit to
the JSC for its review, comment and approval, such amendment to the Development
Plan.

        (d)    Performance.    Each Party shall use Reasonably Diligent Efforts
to conduct the Development activities allocated to such Party in the Development
Plan in a timely and effective manner. Each Party shall conduct its activities
under the Development Plan in a good scientific manner and comply in all
material respects with all applicable Laws.

        4.3   EMA Approval Additional Studies. If the EMA notifies either Party
that any clinical studies, in addition to the studies included in the DAA filed
by Allos and validated by the EMA on December 15, 2010, and the Existing
Studies, are required to obtain, or are a condition of obtaining, Regulatory
Approval of the Product by the EMA for the Lead Indication, then such studies
will be deemed "EMA Approval Additional Studies" and promptly added to the
Development Plan, by amendment in accordance with Section 4.2(c). Unless the
Parties agree otherwise in writing, Mundipharma shall be responsible for
conducting all EMA Approval Additional Studies and the Parties shall share the
costs of such studies as specified in Section 4.5.

        4.4   Future Development Activities. If either Party wishes to conduct
and/or fund any additional Development activities in the Field (including
company-sponsored studies to explore the utility of the Product in the Field
and/or to expand the label of the Product in such Party's territory to include
additional Indications, but excluding Investigator-Sponsored Studies, and also
including testing one or more New Forms) that are not already set forth in the
Development Plan and are not EMA Approval Additional Studies (each of the
foregoing activities, a "Proposed Study"), the proposing Party shall present to
the other Party's representatives on the JDC the proposed design and timeline
for such Proposed Study and the proposed budget for such Proposed Study. The JDC
shall discuss such Proposed Study at its next meeting, whether regularly
scheduled or specially requested under Section 3.2(c), and the proposing Party
shall provide, within [*] after such JDC meeting (or such longer period of time
as agreed upon in writing by the Parties), any additional information reasonably
requested by the other Party's JDC representatives prior to or during such JDC
meeting.

        (a)    Additional Studies in Oncology Indications.    If within [*]
after the JDC meeting at which a particular Proposed Study in an Oncology
Indication (including a Proposed Study for a New Form that is intended for use
in an Oncology Indication) is discussed

(or such longer period of time as agreed upon in writing by the Parties) (i) the
other Party notifies the proposing Party in writing that the other Party wishes
to cooperate in such Proposed Study on the terms (including design, budget and
timeline) proposed by the proposing Party or (ii) the Parties agree in writing
upon the terms (including design, budget and timeline) under which they will
cooperate in such Proposed Study, then it will be deemed an "Additional Study"
and the Development Plan shall be amended pursuant to Section 4.2(c) to include
such Additional Study and the Parties shall have the diligence obligations with
respect to such Additional Study as provided in Section 4.2(d). The Parties
shall share all Joint Development Costs incurred to conduct such Additional
Study in accordance with the applicable budget and in the proportions set forth
in Section 4.5. All Information resulting from such Additional Study will be
available for use by each Party with respect to the Development and
Commercialization of the Product in the Field in its respective territory in
accordance with the licenses and rights granted or retained under Article 2 of
this Agreement.

        (b)    Additional Studies in Non-Oncology Indications.    Within [*]
after the JDC meeting at which a particular Proposed Study in a Non-Oncology
Indication (including a Proposed Study for a New Form that is intended for use
in a Non-Oncology Indication) is discussed (or such longer period of time as
agreed upon in writing by the Parties), the JDC shall prepare a draft amendment
to the Development Plan that would add such Proposed Study to the Development
Plan (without specifying if such Proposed Study would be an Additional Study or
an Incremental Study) and shall submit such draft amendment to the JSC for
review and approval. Prior to the first JSC meeting at which such proposed
amendment would be discussed, the proposing Party's representatives to the JSC
shall submit to the JSC, for its review and approval, a good faith, commercially
reasonable (given the facts and circumstances at the time, including the
commercial potential of the Product in the Non-Oncology Indication of the
Proposed Study in [*]) proposal for milestone payments that, if such Proposed
Study were to become an Additional Study, would be paid by Mundipharma to Allos
upon (i) the [*], (ii) the [*], (iii) the [*], and (iv) the [*]; provided that
the additional agreed-upon milestone payments for such Non-Oncology Indication
contemplated in this subsection shall apply only to additional Non-Oncology
Indications and not to New Forms only (i.e., the additional agreed-upon
milestone payments will only apply to New Forms that are intended for use in
such additional Non-Oncology Indications for which such milestones are payable).
If, within [*] after the JSC meeting at which a particular Proposed Study in a
Non-Oncology Indication is discussed (or such longer period of time as agreed
upon in writing by the Parties), the JSC decides that the Parties will cooperate
in such Proposed Study upon agreed-upon terms (including design, timeline,
budget and milestone payments), then such Proposed Study will be deemed an
Additional Study, the Development Plan shall be amended pursuant to
Section 4.2(c) to include such Additional Study, Section 7.3 of this Agreement
will be amended to include the agreed-upon milestone payments for such
Non-Oncology Indication, and the Parties shall have the diligence obligations
with respect to such Additional Study as provided in Section 4.2(d). The Parties
shall share all Joint Development Costs incurred to conduct such Additional
Study in accordance with the applicable budget and in the proportions set forth
in Section 4.5. All Information resulting from such Additional Study will be
available for use by each Party with respect to the Development and
Commercialization of the Product in the Field in its respective territory in
accordance with the licenses and rights granted or retained under Article 2 of
this Agreement.

        (c)    Incremental Studies.    

        (i)    If all information reasonably requested by the non-proposing
Party has been provided by the proposing Party and (A) by the [*] after the JDC
meeting at which a particular Proposed Study in an Oncology Indication
(including a Proposed Study for a New Form that is intended for use in an
Oncology Indication) is discussed (or such longer period of time as agreed upon
in writing by the Parties) under Section 4.4(a): (x) (1) the other Party has not
notified the proposing Party in writing that the other Party wishes to cooperate
in such Proposed Study on the terms (including design, budget and timeline)
proposed by the proposing Party, or (2) the Parties have not agreed in writing
upon the terms (including design, budget and timeline) under which they will
cooperate in such Proposed Study, and (y) the other Party has not notified the
proposing Party that it believes that such Proposed Study is substantially
likely to create a Material Impact; or (B) by the [*] after the JSC meeting at
which a particular Proposed Study in a Non-Oncology Indication (including a
Proposed Study for a New Form that is intended for use in a Non-Oncology
Indication) is discussed (or such longer period of time as agreed upon in
writing by the Parties) the JSC does not decide to approve a Proposed Study
under Section 4.4(b), then in either case ((A) or (B)), such Proposed Study will
be deemed an "Incremental Study", the proposing Party shall be deemed the
"Conducting Party" with respect to such Incremental Study, the other Party shall
be deemed the "Non-Conducting Party" with respect to such Incremental Study and,
unless the Conducting Party notifies the JDC that it does not wish to proceed
with such Incremental Study, the Development Plan shall be amended pursuant to
Section 4.2(c) to include such Incremental Study and to specify the Conducting
Party as solely responsible for the conduct and costs of such Incremental Study
and the Non-Conducting Party shall not be responsible for any costs, including
milestones, unless such Non-Conducting Party opts-in to such Incremental Study
pursuant to Section 4.4(c)(v). The Conducting Party may proceed with such
Incremental Study after such amendment of the Development Plan. If the
non-proposing Party believes that such Proposed Study is substantially likely to
create a Material Impact and the proposing Party disputes whether such belief is
reasonable, the JSC shall discuss and decide whether such belief is reasonable.
The Proposed Study shall be deemed an Incremental Study if the JSC decides that
the non-proposing Party's belief is not reasonable. If the JSC agrees that the
non-proposing Party's belief is reasonable, the proposing Party shall not
proceed with the Proposed Study. If the JSC cannot agree whether the
non-proposing Party's belief is reasonable, then such dispute shall be handled
in accordance with Section 13.2.

        (ii)   Notwithstanding each Party's exclusive commercial rights to its
respective territory, Mundipharma shall have the right to conduct an Incremental
Study in patients in the Allos Territory in accordance with the Development
Plan, and Allos shall have the right to conduct an Incremental Study in patients
in the Licensed Territory in accordance with the Development Plan.

        (iii) The Conducting Party shall promptly inform the JDC of any material
changes it wishes to make to an Incremental Study, including the budget
therefor, and the Development Plan shall be amended to address them unless the
Non-Conducting Party believes that the amendment is substantially likely to have
a Material Impact, in which case the JSC shall review such amendment and approve
it only if the JSC decides that the Non-Conducting Party's belief is not
reasonable. If the JSC agrees that the Non-Conducting Party's

belief is reasonable, the proposing Party shall proceed without such material
changes. If the JSC cannot agree whether the Non-Conducting Party's belief is
reasonable, then such dispute shall be handled in accordance with Section 13.2.
The Conducting Party may suspend or terminate an Incremental Study without
obtaining approval from the JDC or the JSC if there is a Safety Reason or such
suspension or termination is required by a Regulatory Authority or
investigational review board; provided, the Conducting Party shall promptly
notify the JDC of any such suspension or termination.

        (iv)  Promptly following the availability of interim data from or
completion of an Incremental Study, the Conducting Party shall deliver to the
JDC the top-line data summary from such Incremental Study. The Non-Conducting
Party will have no rights to use any Information resulting from such Incremental
Study in any filings with Regulatory Authorities, for Commercialization in its
territory, or otherwise, provided, however, that the Non-Conducting Party may
file required safety information with the applicable Regulatory Authorities in
its territory in accordance with Section 4.8(b).

        (v)   Opt-In.

        (A)  Within [*] of the Conducting Party having obtained final results in
an Incremental Study establishing Clinical Proof of Concept, such Conducting
Party shall deliver to the Non-Conducting Party the top-line data summary from
such Incremental Study (the delivery date of such top-line data summary, the
"Opt-In Option Date"), and the Non-Conducting Party with respect to such
Incremental Study shall have the right (the "Opt-In Right") to convert such
Incremental Study to an Additional Study by (1) making a payment to the
Conducting Party equal to the amount that would have been such Non-Conducting
Party's share (which shall be determined pursuant to Section 4.5 as of the time
of the Non-Conducting Party's exercise of such Opt-In Right) of the development
costs already incurred by the Conducting Party (which shall be calculated in
accordance with Section 1.87, as if such Incremental Study were a Shared Study,
but without regard to whether such costs are within [*] of the budget for such
Incremental Study as specified in the Development Plan), plus a premium of [*]
of such amount (such payment, the "Opt-In Payment"), (2) agreeing with the
Conducting Party upon the budget, timeline and allocation of operational
responsibility for Development activities, if any, to be performed with respect
to such Incremental Study and all Related Studies after the exercise of such
Opt-In Right and committing to pay its applicable share (pursuant to
Section 4.5) of Joint Development Costs incurred with respect to such
Incremental Study and Related Studies after the exercise of such Opt-In Right,
and (3) with respect to any Incremental Study that is directed to a Non-Oncology
Indication, agreeing with the Conducting Party upon the milestones to be paid by
Mundipharma to Allos upon (w) the [*], (x) the [*], (y) the [*], and (z) the
[*].

        (B)  Opt-In for Incremental Study in an Oncology Indication. If the
Non-Conducting Party with respect to such Incremental Study in an Oncology
Indication is considering exercising its Opt-In Right with respect to such
Incremental Study, it shall, no later than [*] after the Opt-In Option Date,
notify the Conducting Party in writing and shall request that the Conducting
Party provide: (1) an estimate for the Opt-In Payment (the "Opt-In Estimate"),
which estimate shall be based upon the development costs already incurred

those anticipated to be incurred by the Conducting Party, within [*] after the
date of such notice (in each case, calculated as described in
Section 4.4(c)(v)(A)(1)); and (2) a proposal to amend the Development Plan to
convert such Incremental Study to an Additional Study, which amendment shall
address the items specified in Section 4.4(c)(v)(A)(2), to the extent applicable
to such Incremental Study. The Conducting Party shall provide such estimate and
proposal, together with reasonable documentation of the Conducting Party's
already incurred costs, within [*] after such notice (or such longer period of
time as agreed upon in writing by the Parties). The Conducting Party shall
promptly answer all reasonable questions posed by, and provide all additional
documents reasonably requested by, the Non-Conducting Party with respect to the
Opt-In Estimate. The JDC shall discuss such proposed amendment to the
Development Plan at its next meeting, whether regularly scheduled or
specifically requested under Section 3.2(c). The Conducting Party shall provide,
within [*] after such JDC meeting (or such longer period of time as agreed upon
in writing by the Parties), any additional information reasonably requested by
the Non-Conducting Party's JDC representatives prior to or during such JDC
meeting. The Non-Conducting Party shall be deemed to have exercised its Opt-In
Right with respect to such Incremental Study if, within [*] after the JDC
meeting at which such proposed amendment to the Development Plan is discussed
(or such longer period of time as agreed upon in writing by the Parties), the
Conducting Party receives payment of the Opt-In Estimate amount and the JDC
submits to the JSC for review and approval an amendment to the Development Plan
to convert such Incremental Study to an Additional Study, which amendment
addresses the items specified in Section 4.4(c)(v)(A)(2), to the extent
applicable to such Incremental Study. The JSC shall promptly review and approve
such amendment to the Development Plan. In the event that Mundipharma is the
Conducting Party of any Incremental Study in an Oncology Indication which is the
basis upon which Mundipharma receives the [*], and Allos does not exercise its
Opt-In Right pursuant to this Section 4.4(c)(v) with respect to such Incremental
Study, then Mundipharma shall not be obligated to pay the applicable milestone
payment(s) set forth in Section 7.3(a)-(d) with respect to such event for such
Indication.

        (C)  Opt-In for Incremental Study in a Non-Oncology Indication. If the
Non-Conducting Party with respect to such Incremental Study in a Non-Oncology
Indication is considering exercising its Opt-In Right with respect to such
Incremental Study, it shall, no later than [*] after the Opt-In Option Date,
notify the Conducting Party in writing and shall request that the Conducting
Party provide: (1) an Opt-In Estimate for such Incremental Study; and (2) a
proposal to amend the Development Plan to convert such Incremental Study to an
Additional Study, which amendment shall address the items specified in
Section 4.4(c)(v)(A)(2), to the extent applicable to such Incremental Study. The
Conducting Party shall provide such estimate and proposal, together with
reasonable documentation of the Conducting Party's already incurred costs,
within [*] after such notice (or such longer period of time as agreed upon in
writing by the Parties). The Conducting Party shall promptly answer all
reasonable questions posed by, and provide all additional documents reasonably
requested by, the Non-Conducting Party with respect to the Opt-In Estimate. The
JDC shall discuss such proposed amendment to the Development Plan at its next
meeting, whether regularly scheduled or specifically requested under

representatives prior to or during such JDC meeting. If the JDC submits to the
JSC for review and approval an amendment to the Development Plan to convert such
Incremental Study to an Additional Study, which amendment addresses the items
specified in Section 4.4(c)(v)(A)(2), to the extent applicable to such
Incremental Study, then prior to the first JSC meeting at which such proposed
amendment would be discussed, the Conducting Party's representatives to the JSC
shall submit to the JSC, for its review and approval, a good faith, commercially
reasonable (given the facts and circumstances at the time) proposal for
milestone payments to be paid upon the events specified in
Section 4.4(c)(v)(A)(3). If within [*] after the JDC's submission of an
amendment to the Development Plan to convert such Incremental Study to an
Additional Study, which amendment addresses the items specified in
Section 4.4(c)(v)(A)(2), to the extent applicable to such Incremental Study, or
such longer period as agreed upon in writing by the Parties, the JSC approves
such amendment or a revised version thereof and agrees upon milestone payments
to be paid upon the events specified in Section 4.4(c)(v)(A)(3), then the
Non-Conducting Party shall be deemed to have exercised its Opt-In Right with
respect to such Incremental Study upon the latter of the Conducting Party's
receipt of payment of the Opt-In Estimate amount and the effective date of an
amendment to this Agreement that includes such agreed upon milestone payments.
If by the end of the [*] period after the JDC's submission of an amendment to
the Development Plan to convert such Incremental Study to an Additional Study,
which amendment addresses the items specified in Section 4.4(c)(v)(A)(2), to the
extent applicable to such Incremental Study, or such longer period as agreed
upon in writing by the Parties, the JSC has not approved such amendment or a
revised version thereof and agreed upon milestone payments to be paid upon the
events specified in Section 4.4(c)(v)(A)(3), then either Party may submit the
dispute for resolution by the Executive Officers of the Parties. If the Parties'
Executive Officers are unable to agree upon such amendment, or a revised version
thereof, and milestone payments to be paid, then the Conducting Party shall be
entitled to undertake such Incremental Study on its own and the non-Conducting
Party shall be deemed to have not exercised its Opt-In Right with respect to
such Incremental Study.

        (D)  Upon exercise of the Opt-In Right with respect to a particular
study, such study shall cease to be an Incremental Study and shall be deemed to
be an Additional Study, the Parties shall share all future Joint Development
Costs associated therewith in accordance with Section 4.5 and the Parties shall
have the diligence obligations with respect to such Additional Study as provided
in Section 4.2(d). In its first invoice provided pursuant to Section 7.2 after
the actual Opt-In Payment can first be calculated for such former Incremental
Study, the former Conducting Party shall include a credit to the former
Non-Conducting Party for the amount, if any, by which the Opt-In Estimate
exceeded the actual Opt-In Payment or a charge for the amount, if any, by which
the actual Opt-In Payment exceeded the Opt-In Estimate.

        (d)    Related Studies.    The agreement by the Parties to any
Additional Study under this Section 4.4, whether from the outset of the study
pursuant to Sections 4.4(a) or 4.4(b), or through either Party's exercise of its
Opt-In Right to an Incremental Study pursuant to Section 4.4(c)(v), shall be
deemed an agreement by the Parties to cooperate in any and all related studies
necessary for the implementation of such Additional Study or to obtain Drug
Approval in the U.S. and all Major Market Countries in the applicable new
Indication or new formulation that is the subject of such Additional Study
(excluding any related studies that are required exclusively to obtain Drug
Approval in the U.S. and not in any Major Market Country) (each such related

study, a "Related Study"). The terms of Section 4.4 shall apply to any Related
Study in the same manner that they apply to the Additional Study to which such
Related Study relates.

        (e)    Manufacture.    With respect to any Additional Study or
Incremental Study (for which either Party is the Conducting Party) that involves
a New Form, the Conducting Party shall offer the Non-Conducting Party the
opportunity to be the supplier of such New Form. Unless the Non-Conducting Party
informs the Conducting Party that it is not interested in being, or is unable to
be, the supplier of such New Form, the Parties shall negotiate in good faith and
enter into a separate supply agreement that sets forth the terms and conditions
under which the Non-Conducting Party will supply such New Form to the Conducting
Party (in the event of an Incremental Study) or one or both Parties (in the
event of an Additional Study). If the Non-Conducting Party informs the
Conducting Party that it is not interested in being, or is unable to be, the
supplier of such New Form, then the Non-Conducting Party shall grant to the
Conducting Party a non-exclusive, royalty-free limited right and license, under
the Allos Manufacturing Know-How and Allos Patents, or Mundipharma Know-How,
Mundipharma-Controlled manufacturing-related Information and Mundipharma
Patents, as applicable, to manufacture such New Form, with (in the event
Mundipharma is the Conducting Party) the right to sublicense in accordance with
Section 2.1(f) to its Affiliates or, with the prior written consent of the
Non-Conducting Party, to a Third Party manufacturer (which consent shall not be
unreasonably withheld, conditioned or delayed), solely for use in accordance
with this Agreement.

        4.5   Development Costs. The Parties shall each be responsible for their
respective share, as defined in this Section 4.5, of all Joint Development
Costs. Mundipharma shall be responsible for the "Mundipharma Share" of Joint
Development Costs, which share shall initially be forty percent (40%) of the
Joint Development Costs and shall become fifty percent (50%) of the Joint
Development Costs (the "50/50 Threshold") (a) in the calendar quarter after
Mundipharma receives Conditional Approval or (b) if such Conditional Approval is
not obtained, the later of (i) the calendar quarter of the first Drug Approval
in the EU of the Product in the Lead Indication or First Line PTCL, and (ii) the
first calendar quarter in which the Development Cost Differential equals or
exceeds fifteen million Dollars ($15,000,000); provided, if the Development Cost
Differential does not equal or exceed fifteen million Dollars ($15,000,000) by
December 31, 2019, then Allos shall be required to remit the difference between
fifteen million Dollars ($15,000,000) and the Development Cost Differential as
of such date to Mundipharma on or before January 31, 2020 and thereafter the
Mundipharma Share shall be fifty percent (50%). For purposes of this
Section 4.5, the "Development Cost Differential" means the difference between
(A) the cumulative amount of Joint Development Costs borne by Mundipharma
(whether as reimbursement to Allos pursuant to Section 7.2(a) or as Joint

by applicable Law, it shall not, and shall ensure that its Affiliates and
Sublicensees will not, either directly or indirectly, knowingly promote, market,
distribute, import, sell or have sold any Product, including via internet or
mail order, into countries in the Allos Territory. As to such countries in the
Allos Territory, Mundipharma shall not, and shall ensure that its Affiliates and
Sublicensees will not: (i) establish or maintain any branch, warehouse or
distribution facility for any Product in such countries, (ii) engage in any
advertising or promotional activities relating to any Product that are directed

such countries, (iii) solicit orders from any prospective purchaser located in
such countries, or (iv) sell or distribute any Product to any person in the
Licensed Territory who it knows intends to sell any Product in such countries.
If Mundipharma receives any order from a prospective purchaser located in a
country in the Allos Territory, Mundipharma shall immediately refer that order
to Allos, and Mundipharma shall not accept any such orders. Mundipharma shall
not deliver or tender (or cause to be delivered or tendered) any Product into a
country in the Allos Territory. Mundipharma shall not, and shall ensure that its
Affiliates and Sublicensees will not, restrict or impede in any manner Allos'
exercise of its retained rights in the Allos Territory.

        (b)   Allos hereby covenants and agrees that, except with respect to the
named patient supply program in effect as of the Effective Date or any named
patient supply program implemented after the Effective Date and approved by
Mundipharma, insofar as permitted by applicable Law, it shall not, and shall
ensure that its Affiliates and sublicensees will not, either directly or
indirectly, knowingly promote, market, distribute, import, sell or have sold any

any Product that are directed primarily to customers or other purchasers or
users of such Product located in such countries (but, for the avoidance of
doubt, the foregoing shall not in any way restrict Allos from responding to
medical information requests in connection with any such named patient supply
program), (iii) solicit orders from any prospective purchaser located in such
countries, or (iv) except with respect to any such named patient supply program,
sell or distribute any Product to any person in the Allos Territory who it knows
intends to sell any Product in such countries. If Allos receives any order from
a prospective purchaser located in a country in the Licensed Territory except
for orders in connection with any such named patient supply program, Allos shall
immediately refer that order to Mundipharma, and Allos shall not accept any such
orders. Allos shall not deliver or tender (or cause to be delivered or tendered)
any Product into a country in the Licensed Territory except in connection with
any such named patient supply program. Allos shall not, and shall ensure that
its Affiliates and sublicensees will not, restrict or impede in any manner
(other than with respect to any such named patient supply program) Mundipharma's
exercise of its licensed rights in the Licensed Territory. For clarity, nothing
in this Section 6.7(b) shall preclude or prohibit Allos, directly or indirectly,
itself or through its Affiliates or any Third Party, from distributing,
importing, selling or having sold any Product in the Licensed Territory as part
of or in connection with a named patient supply program in effect as of the
Effective Date or a named patient supply program implemented after the Effective
Date and approved by Mundipharma; provided that, on a country-by-country basis
in the Licensed Territory, Allos shall discontinue any such named patient supply
program in a country in the Licensed Territory, in accordance with the terms of
such named patient supply program agreement, upon obtaining the first Drug
Approval in such country unless continuation of such named patient supply
program in such country is approved by Mundipharma. In the event that
Mundipharma approves continuation of such named patient supply program in a
country in the Licensed Territory following Drug Approval in such country, and
if Mundipharma later provides written notice to Allos requesting discontinuation
of such named patient supply program in such country, Allos shall thereafter
discontinue such named patient supply program in such country in accordance with
the terms of such named patient supply program agreement. Notwithstanding the
foregoing, Mundipharma may elect, at any time during the Term, to take over the
existing named patient supply program, on such terms as may be mutually agreed
by the Parties and the existing named patient supply program distributor.

scheduled JCC meeting regarding its Commercialization activities with respect to
Products in the Field in its applicable territory. Each such update shall be in
a form to be agreed by the JCC and shall summarize such Party's significant
Commercialization activities with respect to Products in the Field in its
applicable territory pursuant to this Agreement, covering subject matter at a
level of detail reasonably requested by the Parties and sufficient to enable
each Party to assess the other Party's compliance with its obligations pursuant

shall be reinstated for Product sold in such country during such calendar
quarter.

        (d)    Royalty Reduction Upon Reduction or Cessation of PDX License
Royalties.    In the event royalties cease to be payable by Allos under the PDX

        (e)    Royalty Reduction For Third Party License.    If, during the
Term, Mundipharma deems it necessary to seek or obtain a license from any Third
Party in order to Develop and Commercialize a Product in the Licensed Territory
and provided that Allos is named as or otherwise obtains rights as a licensee or
sublicensee (in respect of the Licensed Territory) under such Third Party
license, Mundipharma shall be entitled to offset against royalties otherwise due
to Allos under this Agreement an amount equal to [*] of any royalties or other
fees paid by Mundipharma to such Third Party under such license; provided,
however, in no event shall the reduction provided for in this Section 7.4(e)

reported in the Financial Times (London edition) on the last business day of
each calendar quarter in the quarter prior to the date of payment.

        7.7    Payment Method; Late Payments.    All payments due hereunder
shall be made in Dollars by wire transfer of immediately available funds into an
account designated by the Party that is owed such payment (such Party, the

before the due date, simple interest shall thereafter accrue on the sum due to
the Payee until the date of payment at the per annum rate of [*] over the
then-current prime rate as reported in The Wall Street Journal or the maximum
rate allowable by applicable Laws, whichever is lower.

        7.8    Records.    Each Party shall keep (and shall ensure that its
Affiliates and sublicensees keep) such records as are required to determine, in
accordance with U.S. generally accepted accounting principles or international
financial reporting standards, as applicable, and this Agreement, the sums or
credits due under this Agreement, including Joint Development Costs and Net
Sales. All such books, records and accounts shall be retained by such Party
until the later of (a) three (3) years after the end of the period to which such
books, records and accounts pertain and (b) the expiration of the applicable tax
statute of limitations (or any extensions thereof), or for such longer period as
may be required by applicable Laws. Each Party shall require its sublicensees to
provide to it a report detailing the foregoing expenses and calculations
incurred or made by such sublicensee, which report shall be made available to
the other Party in connection with any audit conducted by such other Party
pursuant to Section 7.9.

        7.9    Audits.    Each Party shall have the right to have an independent
certified public accountant, reasonably acceptable to the audited Party, have
access during normal business hours, and upon reasonable prior written notice,
to examine only those records of the audited Party (and its Affiliates and
sublicensees) as may be reasonably necessary to determine, with respect to any
calendar year ending not more than three (3) years prior to such Party's
request, the correctness or completeness of any report or payment made under
this Agreement. The foregoing right of review may be exercised only once per
year and only once with respect to each such periodic report and payment.
Reports of the results of any such examination shall be (a) limited to details
of any discrepancies in the audited Party's records relating to the Product,
(b) made available to both Parties and (c) subject to Article 11. If the audit
report concludes that (i) additional amounts were owed by the audited Party, the
audited Party shall pay the additional amounts, with interest from the date
originally due as provided in Section 7.7 or (ii) excess payments were made by
the audited Party, the auditing Party shall reimburse such excess payments, with
interest from the date when the original payment was made, in either case ((i)
or (ii)), within [*] after the date on which such audit report is delivered to
both Parties. The Party requesting the audit shall bear the full cost of the
performance of any such audit, unless such audit, which covers the entire
calendar year, discloses a variance to the detriment of the auditing Party of
more than [*] from the amount of the original report, royalty or payment
calculation, in which case the audited Party shall bear the full cost of the
performance of such audit. The results of such audit shall be final, absent
manifest error.

        7.10 Taxes.

        (a)    Taxes on Income.    Each Party shall be solely responsible for
the payment of all taxes imposed on its share of income arising directly or
indirectly from the efforts of the Parties under this Agreement.

        (b)    Tax Cooperation.    The Parties agree to cooperate with one
another and use reasonable efforts to reduce or eliminate tax withholding or
similar obligations in respect of royalties, milestone payments, and other
payments made by one Party to the other Party under this Agreement. To the
extent a Party is required to deduct and withhold taxes on any payment to the
other Party, it shall pay the amounts of such taxes to the proper Governmental
Authority in a timely manner and promptly transmit to the other Party an
official tax certificate or other evidence of such withholding sufficient to
enable the other Party to claim such payment of taxes. The other Party shall
provide the deducting Party any tax forms that may be reasonably necessary in
order for it not to withhold tax or to withhold tax at a reduced rate under an
applicable bilateral income tax treaty. Each Party shall provide the other with
reasonable assistance to enable the recovery, as permitted by applicable Laws,
of withholding taxes, value added taxes, or similar obligations resulting from
payments made under this Agreement, such recovery to be for the benefit of the
Party bearing such withholding tax or value added tax. Mundipharma shall require
its Sublicensees in the Licensed Territory to cooperate with Allos in a manner
consistent with this Section 7.10(b).

        (c)    Mundipharma Payments.    

        (i)    Taxes Resulting From Mundipharma Action.    If Mundipharma is
required to make a payment to Allos that is subject to a deduction or
withholding of tax, then (A) if such withholding or deduction obligation arises
as a result of any action by Mundipharma, including any assignment or
sublicense, any performance by a Mundipharma Affiliate (pursuant to
Section 14.6), or any failure on the part of Mundipharma to comply with
applicable Laws or filing or record retention requirements, that has the effect
of modifying the tax treatment of the Parties hereto (a "Mundipharma
Payment-Mundipharma Withholding Tax Action"), then the sum payable by
Mundipharma (in respect of which such deduction or withholding is required to be
made) shall be increased to the extent necessary to ensure that Allos receives a
sum equal to the sum which it would have received had no such Mundipharma
Payment-Mundipharma Withholding Tax Action occurred, and (B) otherwise, the sum
payable by Mundipharma (in respect of which such deduction or withholding is
required to be made) shall be made to Allos after deduction of the amount
required to be so deducted or withheld, which deducted or withheld amount shall
be remitted to the proper Governmental Authority in accordance with applicable
Laws. If Allos subsequently receives a refund of any of the tax deducted by
Mundipharma pursuant to (A) above, it shall pay such refunded amount to
Mundipharma within [*] of receipt.

        (ii)    Taxes Resulting From Allos Action.    If Mundipharma is required
to make a payment to Allos that is subject to a deduction or withholding of tax,
then if such withholding or deduction obligation arises as a result of any
action by Allos, including any assignment or sublicense, any performance by an
Allos Affiliate (pursuant to Section 14.6), or

any failure on the part of Allos to comply with applicable Laws or filing or
record retention requirements, that has the effect of modifying the tax
treatment of the Parties hereto (a "Mundipharma Payment-Allos Withholding Tax
Action"), then Mundipharma shall be under no obligation to increase the sum
payable by Mundipharma (in respect of which such deduction or withholding is
required to be made) and the sum payable by Mundipharma shall be net of any
withholding obligations resulting from such Mundipharma Payment-Allos
Withholding Tax Action.

        (d)    Allos Payments.    

        (i)    Taxes Resulting From Allos Action.    If Allos is required to
make a payment to Mundipharma that is subject to a deduction or withholding of
tax, then (A) if such withholding or deduction obligation arises as a result of
any action by Allos, including any assignment or sublicense, any performance by
an Allos Affiliate (pursuant to Section 14.6), or any failure on the part of
Allos to comply with applicable Laws or filing or record retention requirements,
that has the effect of modifying the tax treatment of the Parties hereto (an
"Allos Payment-Allos Withholding Tax Action"), then the sum payable by Allos (in
respect of which such deduction or withholding is required to be made) shall be
increased to the extent necessary to ensure that Mundipharma receives a sum
equal to the sum which it would have received had no such Allos Payment-Allos
Withholding Tax Action occurred, and (B) otherwise, the sum payable by Allos (in
respect of which such deduction or withholding is required to be made) shall be
made to Mundipharma after deduction of the amount required to be so deducted or
withheld, which deducted or withheld amount shall be remitted to the proper
Governmental Authority in accordance with applicable Laws. If Mundipharma
subsequently receives a refund of any of the tax deducted by Allos pursuant to
(A) above, it shall pay such refunded amount to Allos within [*] of receipt.

        (ii)    Taxes Resulting From Mundipharma Action.    If Allos is required
to make a payment to Mundipharma that is subject to a deduction or withholding
of tax, then if such withholding or deduction obligation arises as a result of
any action by Mundipharma, including any assignment or sublicense, any
performance by a Mundipharma Affiliate (pursuant to Section 14.6), or any
failure on the part of Mundipharma to comply with applicable Laws or filing or
record retention requirements, that has the effect of modifying the tax
treatment of the Parties hereto (an "Allos Payment-Mundipharma Withholding Tax
Action"), then Allos shall be under no obligation to increase the sum payable by
Allos (in respect of which such deduction or withholding is required to be made)
and the sum payable by Allos shall be net of any withholding obligations
resulting from such Allos Payment-Mundipharma Withholding Tax Action.

Joint Patents and Mundipharma Patents (collectively, the "Allos Prosecuted
Patents"). As between the Parties, [*] shall bear all costs incurred by Allos in
connection with the preparation, filing, prosecution or maintenance of any Allos
Prosecuted Patent in the Allos Territory. Prior to any filing or extension,
Allos shall provide Mundipharma reasonable opportunity to review and comment on
such prosecution efforts regarding the Allos Prosecuted Patents (including the
PDX Patents, to the extent the PDX Licensor consults with Allos and provides
Allos the right to review and comment on the same, in each case as is required
pursuant to section 8.2 of the PDX License Agreement) as follows: Allos shall
promptly provide Mundipharma with copies of all material communications from any
patent authority regarding the Allos Prosecuted Patents, and shall provide
Mundipharma, for its review and comment, with drafts of any material filings or
responses to be made to such patent authorities in a reasonable amount of time
in advance of submitting such filings or responses. Allos shall consider in good
faith any reasonable comments thereto provided by Mundipharma in connection with
the prosecution of the Allos Prosecuted Patents. Each Party shall provide the
other Party all reasonable assistance and cooperation in the patent prosecution
efforts provided in this Section 8.3(a), including executing any other required
documents or instruments for such prosecution.

        (b)   Except with respect to the PDX Patents, if Allos decides anywhere
in the Licensed Territory to abandon any Allos Prosecuted Patent or not to apply
for an extension of any Allos Prosecuted Patent, including a supplementary
protection certificate or equivalent thereof, Mundipharma shall have the right
to assume Allos' rights and responsibilities under this Section 8.3 with respect
to such Allos Prosecuted Patent, and in connection with assuming such

rights and responsibilities, Mundipharma shall be entitled to apply for any such
extension (including a supplementary protection certificate or equivalent
thereof) and Mundipharma shall thereafter become responsible for the prosecution
and maintenance of such Allos Prosecuted Patent in the Licensed Territory. With
respect to any PDX Patent, the foregoing shall apply only if and to the extent
that Allos assumes responsibility and control (after consultation with
Mundipharma as to whether to assume such responsibility or control) of the
prosecution and maintenance of such PDX Patent in accordance with the PDX
License Agreement.

        8.4   Patent Enforcement in the Licensed Territory.

        (a)    Notification.    If either Party become aware of any existing or
threatened infringement of the Allos Patents, Joint Patents or Mundipharma
Patents in the Field in the Licensed Territory by a Third Party ("Licensed
Territory Infringement"), it shall promptly notify the other Party in writing to
that effect and the Parties will consult with each other regarding any actions
to be taken with respect to such Licensed Territory Infringement.

        (b)    Enforcement Rights.    For any Licensed Territory Infringement,
each Party shall share with the other Party all Information available to it
regarding such actual or alleged infringement. As between the Parties,
Mundipharma shall have the first right, but not the obligation, to bring an
appropriate suit or other action against any person or entity engaged in such
Licensed Territory Infringement, at Mundipharma's cost and expense. Mundipharma
shall have a period of ninety (90) days after its receipt or delivery of notice
under Section 8.4(a) to elect to so enforce the Joint Patents, Allos Patents or
Mundipharma Patents against such Licensed Territory Infringement (or to settle
or otherwise secure the abatement of such Licensed Territory Infringement). If
Mundipharma fails to commence a suit to enforce the applicable Joint Patents,
Allos Patents or Mundipharma Patents against such Licensed Territory
Infringement or to settle or otherwise secure the abatement of such Licensed
Territory Infringement within such period, then Allos shall have the right, but
not the obligation, to commence a suit or take action to enforce such Joint
Patents, Allos Patents or Mundipharma Patents against such Licensed Territory
Infringement at its own cost and expense. In this case, Mundipharma shall take
appropriate actions in order to enable Allos to commence a suit or take the
actions set forth in the preceding sentence. If neither Mundipharma nor Allos
commences a suit or takes action to enforce the PDX Patents, the PDX Licensor
may elect to take such enforcement action.

        (c)    Collaboration.    Each Party shall provide to the enforcing Party
reasonable assistance in such enforcement, at such enforcing Party's request and
expense, including joining such action as a party plaintiff if required by
applicable Laws to pursue such action. The enforcing Party shall keep the other
Party regularly informed of the status and progress of such enforcement efforts,
shall reasonably consider the other Party's comments on any such efforts, and
shall seek consent of the other Party in any important aspects of such
enforcement, including determination of litigation strategy and filing of
material papers to the competent court, which shall not be unreasonably
withheld, conditioned or delayed. The non-enforcing Party shall be entitled to
separate representation in such matter by counsel of its own choice and at its
own expense, but such Party shall at all times cooperate fully with the
enforcing Party.

        (d)    Settlement.    

        (i)    Mundipharma shall not settle any claim, suit or action that it
brought under Section 8.4(b) in any manner that would negatively impact the
applicable Allos Patents, Joint Patents or Mundipharma Patents or that would
limit or restrict the ability of Allos to Develop, make, use, import, offer for
sale, sell or otherwise Commercialize Products anywhere in the Field in the
Allos Territory or to make or have made Products anywhere in the world, without
the prior written consent of Allos, which consent shall not be unreasonably
withheld, conditioned or delayed. Nothing in this Article 8 shall require Allos
to consent to any settlement that is reasonably anticipated by Allos to have a
substantially adverse impact upon any Allos Patent, Joint Patent or Mundipharma
Patent in the Allos Territory, or to the Development, Commercialization, use,
importation, offer for sale or sale of Products in the Field in the Allos
Territory, or to the manufacture of Products anywhere in the world.

        (ii)   Allos shall not settle any claim, suit or action that it brought
under Section 8.4(b) in any manner that would negatively impact the applicable
Allos Patents, Joint Patents or Mundipharma Patents or that would limit or
restrict the ability of Mundipharma to Develop, make, use, import, offer for
sale, sell or otherwise Commercialize Products anywhere in the Licensed
Territory in the Field, without the prior written consent of Mundipharma, which
consent shall not be unreasonably withheld, conditioned or delayed. Nothing in
this Article 8 shall require Mundipharma to consent to any settlement that is
reasonably anticipated by Mundipharma to have a substantially adverse impact
upon any Allos Patent, Joint Patent or Mundipharma Patent in the Licensed
Territory, or to the Development, manufacture, Commercialization, use,
importation, offer for sale or sale of Products in the Licensed Territory in the
Field.

        (e)    Expenses and Recoveries.    The enforcing Party bringing a claim,
suit or action under Section 8.4(b) shall be solely responsible for any expenses
incurred by such Party as a result of such claim, suit or action. If such Party
recovers monetary damages in such claim, suit or action, such recovery shall be
allocated first to the reimbursement of any expenses incurred by the Parties in
such litigation, and any remaining amounts shall be retained by the Party
bringing suit, provided that, in the event Mundipharma is the Party bringing
suit, such remaining amounts shall be deemed Net Sales and Mundipharma shall
make a royalty payment to Allos with respect thereto in accordance with
Section 7.4(a).

        8.5   Patent Enforcement in the Allos Territory.

        (a)    Notification.    If either Party becomes aware of any existing or
threatened infringement of the Allos Patents, Joint Patents or Mundipharma
Patents in the Field in the Allos Territory by a Third Party ("Allos Territory
Infringement"), it shall promptly notify the other Party in writing to that
effect and the Parties will consult with each other regarding any actions to be
taken with respect to such Infringement.

Infringement, at Allos' cost and expense, if such Allos Territory Infringement
involves only Allos Patents. As between the Parties, Allos shall have the first
right, but not the obligation, to bring an appropriate suit or other action
against any person or entity engaged in such Allos Territory Infringement, at
Allos' cost and expense, if such Allos Territory Infringement involves Joint
Patents or Mundipharma Patents. Allos shall have a period of ninety (90) days
after its receipt or delivery of notice under Section 8.5(a) to elect to so
enforce the Joint Patents or Mundipharma Patents against such Allos Territory
Infringement (or to settle or otherwise secure the abatement of such Allos
Territory Infringement). If Allos fails to commence a suit to enforce the
applicable Joint Patents or Mundipharma Patents against such Allos Territory
Infringement or to settle or otherwise secure the abatement of such Allos
Territory Infringement within such period, then Mundipharma shall have the
right, but not the obligation, to commence a suit or take action to enforce such
Joint Patents or Mundipharma Patents against such Allos Territory Infringement
at its own cost and expense. In this case, Allos shall take appropriate actions
in order to enable Mundipharma to commence a suit or take the actions set forth
in the preceding sentence. If neither Allos nor Mundipharma commences a suit or
takes action to enforce the PDX Patents, the PDX Licensor may elect to take such
enforcement action.

reasonable assistance in such enforcement, at such enforcing Party's request and

separate representation in such matter by counsel of its own choice and at its
own expense, but such Party shall at all times cooperate fully with the
enforcing Party.

that it brought under Section 8.5(b) in any manner that would negatively impact
the applicable Joint Patents or Mundipharma Patents or that would limit or
restrict the ability of Mundipharma to Develop, make, use, import, offer for

not be unreasonably withheld, conditioned or delayed. Nothing in this Article 8
shall require Mundipharma to consent to any settlement that is reasonably

        8.6   PDX Patents. Each Party's rights under this Article 8 with respect
to the prosecution, maintenance and enforcement of any PDX Patent shall be
subject to the rights of the PDX Licensor to prosecute, maintain and enforce
such PDX Patent. Notwithstanding the foregoing, Allos shall provide Mundipharma
reasonable opportunity to review and comment on prosecution efforts regarding
the PDX Patents to the extent the PDX Licensor consults with Allos and provides
Allos the right to review and comment on the same, in each case as is required
pursuant to section 8.2 of the PDX License Agreement.

        8.7   Infringement of Third Party Rights in the Licensed Territory.
Subject to Article 10, if a Product used or sold by Mundipharma, its Affiliates
or Sublicensees becomes the subject of a Third Party's claim or assertion of
infringement of a Patent granted by a jurisdiction within the Licensed Territory
(each such claim or assertion a "Third Party Claim"), Mundipharma shall promptly
notify Allos and the Parties shall agree on and enter into a common interest
agreement, pursuant to which the Parties will agree to work toward their shared,
mutual interest in the outcome of such potential dispute, and thereafter, the
Parties shall promptly meet to consider the Third Party Claim and the
appropriate course of action. Mundipharma shall be solely responsible for the
defense of any such Third Party Claim, at Mundipharma's cost and expense;
provided that the provisions of Section 8.4 shall govern the right of
Mundipharma to assert a counterclaim of infringement of any Allos Patents, Joint
Patents or Mundipharma Patents.

        8.8   Patent Marking. Mundipharma and its Affiliates and Sublicensees
shall mark any Product marketed and sold by Mundipharma or its Affiliates or
Sublicensee hereunder with appropriate patent numbers or indicia; provided,
however, that Mundipharma shall only be required to so mark such Product to the
extent such markings or such notices would affect recoveries of damages or
equitable remedies available under applicable Laws with respect to infringement
of Patents in the Licensed Territory.

        8.9   Trademark Matters.

        (a)    Trademark License.    Subject to the terms and conditions of this
Agreement, Allos hereby grants to Mundipharma an exclusive, royalty-free right

        (b)    Sublicense Rights.    Mundipharma shall have the right to grant
sublicenses of the license granted in Section 8.9(a) solely to a Sublicensee
that has received a sublicense from Mundipharma of the license granted to
Mundipharma in Section 2.1(b). Such sublicense shall be included in the
applicable Mundipharma Sublicense Agreement, which shall obligate such
Sublicensee to comply with the terms and conditions of Section 8.9(c) through
8.9(f), Section 8.9(h) and Section 8.9(j) as if such Sublicensee were
Mundipharma.

        (c)    Ownership of the Licensed Marks.    Mundipharma agrees and

Allos is and will continue to be the sole and exclusive owner of all rights,
title and interest in and to each Licensed Mark in any form or embodiment
thereof and agrees that all goodwill associated with or attached to the Licensed
Marks arising out of the use thereof by Mundipharma shall inure to the benefit
of Allos.

        (d)    Registration; No Contest.    Allos has registered, or has filed
applications for registration of, the Licensed Marks in those countries and
jurisdictions in the Licensed Territory indicated in Exhibit C. Upon the written
request of Mundipharma, Allos will register or attempt to register the Licensed
Marks in such other countries in the Licensed Territory in which Mundipharma
reasonably expects to file a Drug Approval Application and seek to obtain
Regulatory Approval. Mundipharma agrees that it will neither contest, oppose or
challenge, nor assist any party in contesting, opposing or challenging, Allos'
ownership of the Licensed Marks or the distinctiveness or validity of the
Licensed Marks. Mundipharma agrees that it will not at any time do or suffer to
be done any act or thing that will in any way impair Allos' ownership of or
rights in and to the Licensed Marks or any registration thereof. Mundipharma
will not register or attempt to register any Licensed Mark in any jurisdiction
nor oppose Allos' registration of any Licensed Mark, alone or with other words
or designs, in any jurisdiction; provided, however, Mundipharma shall have the
right to register as domain names the Licensed Marks in any country in the
Licensed Territory using any country code domain names for such country, but
specifically excluding the domain names set forth in the Letter Agreement.
Mundipharma shall, on the reasonable request of Allos, give Allos or its
authorized representative necessary information as to the use of the Licensed
Marks pursuant to this Agreement which Allos may require and will render any
assistance reasonably required by Allos in obtaining or maintaining the
registrations of the Licensed Marks. Any costs incurred by Mundipharma in
rendering such assistance shall be [*] and shall be [*].

that are Commercialized in the Field in the Licensed Territory in accordance
with applicable Law and current pharmaceutical industry standards of quality,
including the terms of all applicable Regulatory Approvals.

Marks. Additionally, Mundipharma shall:

Licensed Marks shall not be impaired. Without prejudice to the generality of the
foregoing, Mundipharma shall use Reasonably Diligent Efforts to ensure in
particular that each Licensed Mark is correctly spelled, is accompanied by words
accurately describing the nature of the goods or services to which it relates,
and is displayed as set forth in Exhibit C and that any text, graphics or
designs adjacent to any Licensed Mark does not put the Licensed Mark or Allos in
a negative or derogatory light;

any part of its business under a business name or trading style which
incorporates any of the Licensed Marks or which might materially impair the
validity, reputation or distinctiveness of any of the Licensed Marks; and

        (vii) neither use nor display any of the Licensed Marks in such relation
to any other mark or marks owned by any Third Party or Mundipharma so as to
suggest that the multiple marks constitute a single or composite trademark,
service mark, or are under the same proprietorship.

        (g)    Out-of-Pocket Costs.    All out-of-pocket expenses incurred by
Allos in connection with pursuit of registration and maintenance of registered
Licensed Marks in the Licensed Territory during the Term, including in
connection with filing of necessary maintenance and use documents, applying for
renewal, and payment of any required taxes or fees due in connection with such
applications or registrations, shall be [*] and shall be [*].

        (A)  If either Party or its Affiliate becomes aware of actual or
threatened infringement in the Licensed Territory of any Licensed Mark or of a
mark or name confusingly similar to any Licensed Mark, such Party shall promptly
notify the other Party in writing. Mundipharma shall have the first right, but
not the obligation, to bring infringement or unfair competition actions in the

action described in this Section 8.9(i)(A) and, if required by Law, join such
action. Mundipharma shall bear the entire cost and expense associated with such
action, and any recovery resulting from such proceeding shall belong entirely to
Mundipharma. However, Mundipharma shall not settle or accept any settlement from
any Third Party in connection with the adverse use of any Licensed Mark without
the prior written consent of Allos (such consent not to be unreasonably
withheld, conditioned or delayed).

infringement or to bring and diligently prosecute an infringement or unfair
competition action to terminate such threatened or actual infringement within
ninety (90) days of notice pursuant to Section 8.9(i)(A), Allos may thereafter
take such action as it deems appropriate, including bringing, at its own
expense, an infringement action or filing any other appropriate action or claim
related to infringement of the Licensed Mark in the Licensed Territory against
any Third Party. Mundipharma shall, at the request and expense of Allos,
cooperate and provide reasonable assistance in any action described in this
Section 8.9(i)(B) and, if required by Law, join such action. Allos shall bear
the entire cost and expense associated with such action, and any recovery
resulting from such proceeding shall belong entirely to Allos.

        (j)    Third Party Trademark Litigation.    In the event of the
initiation of any suit by a Third Party against Mundipharma for trademark
infringement involving Commercialization of Products in the Field in the
Licensed Territory, Mundipharma shall promptly notify Allos in writing.
Mundipharma shall have the right, but not the obligation, to defend such suit at
its expense.

        (k)    Alternative Trademark.    If (x) any of the events set forth in
Section 12.5(i)-(vi) shall have occurred with respect to Allos, (y) a Regulatory
Authority in any country in the Licensed Territory refuses to permit Mundipharma
to use a Licensed Mark in connection with the Commercialization of Products in
such country, or a Licensed Mark is found by a court of competent jurisdiction
to infringe Third Party rights in such country, or (z) if Mundipharma determines
in good faith that such Licensed Mark is not commercially viable in any country
in the Licensed Territory and Allos reasonably agrees in writing (not to be
unreasonably withheld, conditioned or delayed), then Mundipharma may use an
alternative trademark owned by Mundipharma and approved by the JSC, in lieu of
such Licensed Mark, in connection with the Commercialization of Products in such
country.

        (l)    Assignment.    Allos hereby transfers and assigns to Mundipharma,
its successors and assigns, Allos' entire ownership interest and title in the
trademark [*], for use in connection with Commercializing Products in the Field
in the Licensed Territory, together with any and all goodwill assigned
therewith, to be held and enjoyed by Mundipharma, its successors and assigns, to
the full end of the term thereof, as may be extended by Law as fully and
entirely as the same would have been held and enjoyed by Allos if this transfer
and assignment had not been made. From and after the Effective Date, Mundipharma
shall pay all of the out-of-pocket costs and expenses associated with
registering and maintaining the [*] trademark in the Licensed Territory. The
Parties agree to execute and deliver, within [*] days after the Effective Date,
a trademark assignment agreement (or confirmation of trademark assignment)
reflecting the terms set forth in this Section 8.9(l).

necessary or advisable, Mundipharma may request that Allos enter into one or
more coexistence agreements with Third Parties in respect of trademarks that
such Third Parties own and/or utilize in the Licensed Territory, that are
confusingly or otherwise substantially similar to the Licensed Mark. Allos
agrees to cooperate with Mundipharma and provide such reasonable and timely
assistance, at Mundipharma's expense, as Mundipharma may require in order that
Allos and each such Third Party may consummate an appropriate coexistence
agreement.

Claim with counsel of its choice. The Indemnifying Party shall not settle any
Claim without the prior written consent of the Indemnified Party, not to be
unreasonably withheld, unless the settlement involves only the payment of money.

not assume and conduct the defense of the Claim as provided above, (a) the
Indemnified Party may defend against, consent to the entry of any judgment, or
enter into any settlement with respect to such Claim in any manner the
Indemnified Party may deem reasonably appropriate (and the Indemnified Party
need not consult with, or obtain any consent from, the Indemnifying Party in

OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES
ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY
NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING,

        (e)   was independently discovered or developed by the receiving Party
or its Affiliate without access to or aid, application or use of the other
Party's Confidential Information, as evidenced by a contemporaneous writing.

        11.2    Authorized Disclosure.    Notwithstanding the obligations set
forth in Section 11.1, a Party or its Affiliate may disclose the other Party's
Confidential Information and the terms of this Agreement to the extent:

        (a)   such disclosure is reasonably necessary (i) for the filing or

stringent than those contained in this Agreement;

        (c)   such disclosure is reasonably necessary to any bona fide potential
or actual investor, acquiror, merger partner, or other financial or commercial

having a minimum term of five (5) years; or

        (d)   such disclosure is reasonably necessary to comply with applicable
Laws, including regulations promulgated by applicable security exchanges, court
order, administrative subpoena or other order.

Notwithstanding the foregoing, in the event a Party or its Affiliate is required
to make a disclosure of the other Party's Confidential Information pursuant to
Section 11.2(a) or 11.2(d), such Party shall promptly notify the other Party of
such required disclosure and, upon the other Party's request, such Party and its
Affiliates shall use reasonable efforts to obtain, or to assist the other Party
in obtaining, a protective order preventing or limiting the required disclosure.

otherwise relating to the Product (each of the foregoing, a "Publication") shall
comply with the strategy established by the JDC pursuant to Section 3.2(a)(vi).
Neither Party nor their Affiliates may submit for publication, publish or
present a Publication without the opportunity for prior review by the other
Party, except to the extent required by applicable Laws. A Party seeking, or
whose Affiliate is seeking, to submit, publish or present a Publication shall
provide the other Party the opportunity to review and comment on the proposed
Publication at least fifteen (15) days prior to its intended submission for
publication or presentation. The other Party shall provide the Party seeking, or
whose Affiliate is seeking, to publish or present with its comments in writing,
if any, within ten (10) days after receipt of such proposed Publication. The
Party seeking, or whose Affiliate is seeking, to publish or present shall
consider in good faith any comments thereto provided by the other Party and
shall comply with the other Party's request to remove any and all of such other
Party's Confidential Information from the proposed Publication; provided,
however, that Information arising from a Shared Study shall not be considered
the other Party's Confidential Information for purposes of this Section 11.3. In
addition, the Party seeking, or whose Affiliate is seeking, to publish or
present shall delay the submission for a period of up to thirty (30) days in the
event that the other Party can demonstrate reasonable need for such delay in
order to prepare and file a patent application for which it has prosecution
control pursuant to this Agreement. If the other Party fails to provide its
comments to the Party seeking, or whose Affiliate is seeking, to publish or
present within such ten (10)-day period, such other Party shall be deemed not to
have any comments, and the Party seeking, or whose Affiliate is seeking, to
publish or present shall be free to submit for publication or present in
accordance with this Section 11.3(b) after the fifteen (15)-day period has
elapsed. The Party seeking, or whose Affiliate is seeking, to publish or present
shall provide the other Party a copy of the manuscript, abstract or presentation
at the time of the submission or presentation, as applicable. Each Party agrees
to acknowledge the contributions of the other Party and its Affiliates and their
employees in all publications, as scientifically appropriate.

execution of this Agreement in the form attached as Exhibit B, which shall be
issued on or promptly after the Effective Date.

        (c)   After release of such press release, if either Party or its
Affiliate desires to make a public announcement concerning the material terms of
this Agreement, or any clinical or regulatory announcements, such Party shall
give reasonable prior advance notice of the proposed text of such announcement
to the other Party for its prior review and approval (except as otherwise
provided herein), such approval not to be unreasonably withheld. A Party
commenting on such a proposed announcement shall provide its comments, if any,
within five (5) business days after receiving the announcement for review, or
such shorter period as may be reasonably required in order for the proposing
Party to comply with any applicable deadline for making such announcement (as
such deadline is communicated by the proposing Party to the

commenting Party). In addition, where required by applicable Laws, including
regulations promulgated by applicable security exchanges, such Party or its
Affiliate shall have the right to make a press release announcing the
achievement of each milestone under this Agreement as it is achieved, the
achievements of Regulatory Approvals in the Licensed Territory as they occur, or
any other material event with respect to this Agreement or the Parties'
performance thereof, subject only to the review procedure set forth in the
preceding sentence; provided that the review period shall be reduced to two
(2) business days (or such shorter period as may be reasonably required in order
for the proposing Party to comply with any applicable deadline for making such
press release, as such deadline is communicated by the proposing Party to the
commenting Party) if the deadline for making such disclosure is five (5) or
fewer business days after such achievement or event. In relation to the other
Party's review of such an announcement, such other Party may make specific,
reasonable comments on such proposed press release within the prescribed time
for commentary, but shall not withhold its consent to disclosure of the
information that the relevant milestone or Regulatory Approval has been achieved
or material event has occurred. Neither Party nor their Affiliates shall be
required to seek the permission of the other Party to repeat any information
regarding the terms of this Agreement that has already been publicly disclosed
by such Party or its Affiliate, or by the other Party or its Affiliate, in
accordance with this Section 11.4, provided such information remains accurate as
of such time.

        (d)   The Parties acknowledge that either or both Parties may be
obligated to file under applicable Laws a copy of this Agreement with the U.S.
Securities and Exchange Commission ("SEC") or other Governmental Authorities.
Each Party shall be entitled to make such a required filing, provided that it
requests confidential treatment of the commercial terms and sensitive technical
terms hereof and thereof to the extent such confidential treatment is reasonably
available to such Party. In the event of any such filing, each Party will
provide the other Party with a copy of this Agreement marked to show provisions
for which such Party intends to seek confidential treatment and shall reasonably
consider and incorporate the other Party's comments thereon to the extent
consistent with the legal requirements, with respect to the filing Party,
governing disclosure of material agreements and material information that must
be publicly filed.

        11.5    Prior Confidentiality Agreements.    The First Confidentiality
Agreement and the Second Confidentiality Agreement remain in full force and
effect and are not superseded by this Agreement. All Information disclosed by a
Party or its Affiliate to the other Party or its Affiliate pursuant to the First
Confidentiality Agreement or the Second Confidentiality Agreement shall be
deemed to be such Party's Confidential Information disclosed hereunder and the
other Party and its Affiliates and disclosees shall have the confidentiality,
non-use and non-disclosure obligations set forth in this Article 11. In the
event that any such obligations conflict with the obligations set forth in the
First Confidentiality Agreement or the Second Confidentiality Agreement, then
the other Party and its Affiliates and disclosees shall comply with the
obligations set forth in this Article 11.

        11.6    Return of Confidential Information.    Except as otherwise set
forth in this Agreement, upon termination of this Agreement, the receiving Party
will promptly return all of the disclosing Party's Confidential Information,

Knowledge of any unauthorized use or disclosure of the other Party's
Confidential Information, it will promptly notify the other Party of such
unauthorized use or disclosure.

        11.8    Exclusive Property.    All Confidential Information is the sole
and exclusive property of the disclosing Party and the permitted use thereof by

Information for any other purpose.

ARTICLE 12

TERM AND TERMINATION

        12.1    Term.    This Agreement shall become effective on the Effective
Date and, unless earlier terminated pursuant to this Article 12, shall remain in
effect on a country-by-country basis until the expiration of the Royalty Term
for the Product in such country (the "Term"). Upon the expiration of the Royalty
Term for a Product in a particular country, the licenses granted by Allos to
Mundipharma under Sections 2.1(a) and 2.1(b) in such country shall become
fully-paid and royalty free and, except for the sublicenses granted thereunder
to the Allos Technology licensed to Allos under the PDX License Agreement, such
licenses shall remain exclusive. Upon the expiration of the Royalty Term for a
Product in a particular country pursuant to Section 7.4(b)(i) or
Section 7.4(b)(iii), the sublicenses granted under Sections 2.1(a) and 2.1(b) to
the Allos Technology licensed to Allos under the PDX License Agreement in such
country shall become non-exclusive.

        12.2    Termination for Breach.    Each Party (the "Non-Breaching
Party") shall have the right to terminate this Agreement in its entirety or on a
country-by-country basis immediately upon written notice to the other Party (the
"Breaching Party") if the Breaching Party materially breaches its obligations
under this Agreement and, after receiving written notice identifying such
material breach in reasonable detail (a "Default Notice"), fails to cure such
material breach within [*] after delivery of the Default Notice (or within [*]
after delivery of the Default Notice in the event such material breach is solely
based on the Breaching Party's failure to pay any amounts due hereunder). For
the avoidance of doubt, in addition to any other failure to pay any amounts due
hereunder, failure by either Party to pay any portion of its Joint Development
Costs under this Agreement shall constitute a material breach of such non-paying
Party's obligations under this Agreement.

        12.3    Termination for Patent Challenge.    Mundipharma will provide
written notice to Allos at least [*] prior to Mundipharma or its Affiliates or
Sublicensees (individually or in association with any other person or entity)
bringing an action to challenge the validity, enforceability or scope of any
Allos Patents or Joint Patents anywhere in the world. In the event that
Mundipharma or its Affiliates or Sublicensees (individually or in association
with any other person or entity) brings an action to challenge the validity,
enforceability or scope of any Allos Patents or Joint Patents anywhere in the
world, Allos shall have the right to terminate this Agreement in its entirety
immediately upon written notice to Mundipharma.

        12.4    Unilateral Termination by Mundipharma.    

        (a)   Termination Upon Written Notice; Change of Control of Allos.

          (i)  Notwithstanding any other provision of this Agreement,
Mundipharma may terminate this Agreement in its entirety upon [*] prior written
notice to Allos at any time.

         (ii)  Notwithstanding the provisions of subclause (i) above, promptly,
but no later than [*] following the completion of any Change of Control of
Allos, Allos shall provide written notice of the same to Mundipharma (an "Allos
Change of Control Notice"). If Mundipharma elects to terminate this Agreement as
a result of such Change of Control of Allos, Mundipharma shall provide [*] prior
written notice of termination to Allos no later than [*] after delivery of the
Allos Change of Control Notice and, in the absence of such notice of termination
within [*] after the Allos Change of Control Notice, this Agreement will remain
in full force and effect. For the avoidance of doubt, the provisions of this
Section 12.4(a)(ii) shall in no way impact Mundipharma's right in
Section 12.4(a)(i) to terminate this Agreement at any time upon [*] prior
written notice to Allos.

        (b)    Termination by Regulatory Authority.    Should any serious and
unexpected events or issues occur with respect to the safety of any Product as a
result of which (i) Regulatory Approval for such Product is terminated or
suspended in one or more regulatory jurisdictions in the Licensed Territory, or
(ii) a Regulatory Authority directs or requests discontinuance of development,
use or sale of such Product in one or more countries in the Licensed Territory,
then Mundipharma's obligations under this Agreement with respect to such Product
will be suspended in such regulatory jurisdiction(s) and/or country(ies) (as
applicable) until such serious safety event is resolved and Regulatory Approval
for such Product is no longer terminated or suspended or the Regulatory
Authority has given approval again to distribute or sell such Product (as
applicable) in such regulatory jurisdiction(s) and/or country(ies). Mundipharma
may, upon written notice to Allos, terminate this Agreement pursuant to this
Section 12.4(b) if Mundipharma's obligations under this Agreement are suspended
pursuant to this Section 12.4(b) for a period in excess of twelve (12) months.

        (c)    Breach or Termination of PDX License Agreement.    

          (i)  Within [*] of receiving written notice from the PDX Licensor that
Allos is in material breach of the PDX License Agreement (a "PDX Breach"), Allos
shall provide Mundipharma with written notice of such PDX Breach. To the extent
that Allos is unable or unwilling to cure the PDX Breach within the applicable
cure period, and provided that Allos does not dispute the PDX Breach within the
applicable cure period, the Parties hereby agree that Mundipharma shall have the
right, but not the obligation, to cure such PDX Breach (or cause such PDX Breach
to be cured) on behalf of Allos. To the extent that Allos disputes the PDX
Breach, Mundipharma will not proceed to cure or cause such PDX Breach to be
cured in accordance with this Section 12.4(c)(i) unless and until Allos is
unsuccessful in defending against such PDX Breach. In the event Mundipharma
proceeds to cure or causes such PDX Breach to be cured on behalf of Allos in
accordance with this Section 12.4(c)(i), any payments

by the amount so expended by Mundipharma to cure such PDX Breach (or cause such
PDX Breach to be cured) on behalf of Allos.

         (ii)  Notwithstanding the provisions of Section 12.4(c)(i), Mundipharma
may terminate this Agreement immediately on written notice to Allos in the event
that the PDX License Agreement terminates for any reason unless Mundipharma has
consented in writing to such termination.

        (d)    Allos Shortfall Event.    In the event that Allos fails to pay
the Allos Share of Joint Development Costs (in accordance with Section 7.2(b))
in an aggregate amount equal to or in excess of [*] (an "Allos Shortfall
Event"), whether or not such unpaid Allos Share of Joint Development Costs has
been included in the Allos Unpaid Reimbursement Amount deductions taken by
Mundipharma under this Agreement, then upon the occurrence of such Allos
Shortfall Event, Mundipharma may terminate this Agreement upon [*] prior written
notice to Allos.

        12.5    Termination for Bankruptcy.    Each Party shall have the right
to terminate this Agreement in its entirety immediately upon written notice to
the other Party if the other Party (i) applies for or consents to the

or liquidator of itself or of all or a substantial part of its property,
(ii) makes a general assignment for the benefit of its creditors,
(iii) commences a voluntary case under the Bankruptcy Code, (iv) files a
petition seeking to take advantage of any applicable Laws relating to

its debts, (B) the appointment of a trustee, receiver, custodian, liquidator or

        (a)   Upon the early termination of this Agreement pursuant to
Sections 12.2 (except as otherwise provided in Section 12.6(c)), 12.3, 12.4
(other than Section 12.4(c)(ii)) or 12.5, all licenses granted to Mundipharma
under Section 2.1 shall terminate throughout the Licensed Territory (save to the
extent required to enable Mundipharma to sell its inventory of Product which
Allos does not purchase pursuant to Section 12.6(a)(v)) and the following shall
apply (in addition to any other rights and obligations under this Agreement with
respect to such termination):

Conducting Party and Allos has not exercised its Opt-In Right pursuant to
Section 4.4(c)(v), and (B) all domain names registered by Mundipharma in
accordance with Section 8.9(d), and, in connection with the preceding,
Mundipharma shall cooperate as reasonably requested by Allos to effect such
transfer on the applicable domain name registries.

        (ii)    Mundipharma License.    Mundipharma hereby grants to Allos,
effective upon such termination, a non-exclusive, fully paid, royalty-free,
irrevocable license (with the right to grant sublicenses through multiple
tiers), under the Mundipharma Technology, to Develop, make, have made, use,
sell, offer for sale, import and otherwise Commercialize the Products throughout
the Licensed Territory.

        (iii)    Transition Assistance.    Mundipharma shall provide such
reasonable assistance as may be reasonably necessary or useful for Allos to
continue activities Mundipharma is then performing or having performed,
including assigning or amending as appropriate, upon request of Allos, any
agreements or arrangements with Third Party vendors to Develop, distribute, sell
or otherwise Commercialize the Product. To the extent that any such contract
between Mundipharma and a Third Party is not assignable to Allos, Mundipharma
shall reasonably cooperate with Allos to arrange to continue to provide such
services for a reasonable time after termination.

        (iv)    Ongoing Joint Development Costs.    Mundipharma shall continue
to be responsible for the Mundipharma Share (at the current rate pursuant to
Section 4.5) of Joint Development Costs incurred pursuant to the Development
Plan during the [*] period after the effective date of termination of this
Agreement. Notwithstanding the foregoing, if Mundipharma elects to terminate
this Agreement pursuant to (A) Section 12.2, Mundipharma shall not be
responsible for the Mundipharma Share of Joint Development Costs incurred during
the [*] period after the effective date of such termination of this Agreement by
Mundipharma, or (B) Section 12.4(a)(ii) due to a Change of Control of Allos, and
provided that Mundipharma delivers written notice of termination under
Section 12.4(a)(ii) within [*] of delivery of the Allos Change of Control

Development Costs incurred during the [*] period after the effective date of
such termination of this Agreement by Mundipharma.

        (v)    Inventories.    Allos shall have the right to purchase from
Mundipharma any and all of the inventory of Product held by Mundipharma as of
the date of termination at a price equal to the transfer price paid by
Mundipharma to Allos for such inventory. Allos shall notify Mundipharma within
[*] after the date of termination whether Allos elects to exercise such right.
Until Allos exercises such right, or if Allos does not exercise such right
within such [*] period, then Mundipharma shall be entitled to continue selling
such remaining inventory of Product subject to a continuing obligation to pay
royalties pursuant to Section 7.4(a) on Net Sales arising from such sales.

        (vi)    Mundipharma Sublicense Agreements.    Allos shall have the
option, at its sole discretion, to (a) assume Mundipharma's rights and
obligations under any

Mundipharma Sublicense Agreement, or (b) terminate the Mundipharma Sublicense
Agreement in its entirety.

        (b)   Upon the early termination of this Agreement by Mundipharma
pursuant to Section 12.4(c)(ii), Mundipharma may choose, in its sole discretion,
(x) to take those actions and permit Allos to exercise those rights set forth in
Section 12.6(a)(i), (iii), (v) and (vi), or (y) have any or all of the following
apply and, in the event that Mundipharma elects to have the following apply, the
following shall be Mundipharma's sole and exclusive remedy for or relating to
Mundipharma's termination of this Agreement pursuant to Section 12.4(c)(ii):

        (i)    Transfer to Mundipharma.    All of Mundipharma's rights under
Section 2.1 of this Agreement shall continue, and Mundipharma shall require that
Allos promptly takes, and Allos hereby agrees to take, such actions as
Mundipharma may reasonably request, in order to transfer to Mundipharma or its
Affiliates or Sublicensees, free of charge, in respect of the Licensed Territory
only, all of the rights, title and interest retained by Allos pursuant to
Section 2.1(e). In the event of such an assignment, Allos will, at its expense
and at Mundipharma's request, deliver, execute and/or deliver or cause to be
delivered, all such assignments, consents, documents or further instruments of
transfer or license, and take or cause to be taken all such actions as may be
reasonably necessary to effectuate such transfer. Allos will further reconvey
and release to Mundipharma all rights and privileges originally granted to Allos
by Mundipharma under this Agreement (including those granted under Section 8.9),
including those co-exclusive rights, such that all such rights and privileges
will vest exclusively with Mundipharma. Mundipharma will, in such circumstances
not be required to pay any further milestones required under Section 7.3 of this
Agreement, but shall pay to Allos the royalties on all Net Sales of Products in
the Licensed Territory set forth in Section 7.4, after deducting (A) royalty
payments made to the PDX Licensor (with respect to the same Net Sales) in
accordance with Mundipharma's assumption of the rights and responsibilities of
the PDX License Agreement pursuant to Section 12.6(b)(iii); and (B) [*] of
Mundipharma's costs (if any) of curing the consequences of Allos' breach or
actions that resulted in termination under Section 12.4(c)(ii) (such costs do
not, for the avoidance of doubt, include the Allos Unpaid Reimbursement Amount).
Such other provisions hereof as are necessary to administer the calculation and
payment of such royalties will also survive such termination, including any
audit, payment and record retention provisions. Mundipharma will thereafter be
free to exercise its rights to all Product in the Licensed Territory, as
reconveyed and released pursuant to this Section 12.6(b)(i) in the Licensed
Territory as it may see fit, and Allos will not take any actions or make any
omissions to prevent Mundipharma therefrom;

        (ii)    Transition Assistance.    Allos shall provide such reasonable
assistance, at no cost to Mundipharma, as may be reasonably necessary or useful
for Mundipharma to continue Developing the Product throughout the Licensed
Territory to the extent Allos is then performing or having performed such
activities, including assigning or amending as appropriate, upon request of
Mundipharma, any agreements or arrangements with Third Party vendors to Develop
the Product. To the extent that any such contract between Allos and a Third
Party is not assignable to Mundipharma, Allos shall reasonably cooperate with
Mundipharma to arrange to continue to provide such services for a reasonable
time after termination; and

        (iii)    Assumption of PDX License Agreement.    Provided that
Mundipharma is not in breach of this Agreement at the time the PDX License
Agreement terminates, in exercising its rights under Section 12.6(b)(y),
Mundipharma will assume all rights and responsibilities of Allos under the PDX
License Agreement, including the royalties, milestones and sublicense fees
provisions [*], to the extent applicable to the rights granted to Mundipharma
under this Agreement (i.e., in respect of the Licensed Territory only).

        (c)   Upon the early termination of this Agreement by Mundipharma
pursuant to Section 12.4(d), Mundipharma may choose, in its sole discretion,
(x) to take those actions and permit Allos to exercise those rights set forth in
Section 12.6(a)(i), (iii), (v) and (vi), or (y) have any or all of the following
apply and, in the event that Mundipharma elects to have the following apply, the
following shall be Mundipharma's sole and exclusive remedy for or relating to
Mundipharma's termination of this Agreement pursuant to Section 12.4(d) (and,
for clarity, if Mundipharma elects to terminate this Agreement pursuant to
Section 12.2 for reason of Allos' failure to pay any Allos Share of Joint
Development Costs prior to the occurrence of an Allos Shortfall Event, the terms
of Section 12.6(a) shall apply and the terms of this Section 12.6(c) shall not
apply):

        (i)    Transfer to Mundipharma.    All of Mundipharma's rights under
Section 2.1 of this Agreement shall continue, and Mundipharma shall require that
Allos promptly takes, and Allos hereby agrees to take, such actions as
Mundipharma may reasonably request, in order to transfer to Mundipharma or its
Affiliates or Sublicensees, free of charge, in respect of the Licensed Territory
only, all of the rights, title and interest retained by Allos pursuant to
Section 2.1(e), excluding the rights, title and interest of Allos under the PDX
License Agreement unless, and only to the extent, the PDX Licensor consents to
the assignment of such rights, title and interest (and assumption of the
obligations) under the PDX License Agreement in respect of the Licensed
Territory. In the event of such an assignment, Allos will, at its expense and at
Mundipharma's request, deliver, execute and/or deliver or cause to be delivered,
all such assignments, consents, documents or further instruments of transfer or
license, and take or cause to be taken all such actions as may be reasonably
necessary to effectuate such transfer (excluding any transfer of the rights,
title and interest of Allos under the PDX License Agreement unless, and only to
the extent, the PDX Licensor consents to the transfer of such rights, title and
interest (and assumption of the obligations) under the PDX License Agreement in
respect of the Licensed Territory). Allos will further reconvey and release to
Mundipharma all rights and privileges originally granted to Allos by Mundipharma
under this Agreement (including those granted under Section 8.9), including
those co-exclusive rights, such that all such rights and privileges will vest
exclusively with Mundipharma; provided, however, Mundipharma hereby grants to
Allos, effective upon termination under Section 12.4(d), a non-exclusive, fully
paid, royalty-free limited right and license under any Patent Controlled by
Mundipharma that claims the Product or the API or the manufacture or use in the
Field of the Product or the API to Develop, make, have made, use, sell, offer
for sale, import and otherwise Commercialize the Products throughout the Allos
Territory. Mundipharma will, in such circumstances not be required to pay any
further milestones required under Section 7.3 of this Agreement, but shall pay
to Allos the royalties on all Net Sales of Products in the Licensed Territory
set forth in Section 7.4, after deducting (A) royalty payments made to the PDX
Licensor (with respect to the same Net Sales) in accordance with Mundipharma's
assumption of the rights and responsibilities of the PDX License

Agreement pursuant to Section 12.6(c)(iii) and (B) [*] of Mundipharma's costs
(if any) of curing the consequences of Allos' breach or actions that resulted in
termination (such costs do not, for the avoidance of doubt, include the Allos
Unpaid Reimbursement Amount). Such other provisions hereof as are necessary to
administer the calculation and payment of such royalties will also survive such
termination, including any audit, payment and record retention provisions.
Mundipharma will thereafter be free to exercise its rights to all Product in the
Licensed Territory, as reconveyed and released pursuant to this
Section 12.6(c)(i) in the Licensed Territory as it may see fit, and Allos will
not take any actions or make any omissions to prevent Mundipharma therefrom;

        (ii)    Transition Assistance.    Allos shall provide such reasonable
assistance, at no cost to Mundipharma, as may be reasonably necessary or useful
for Mundipharma to continue Developing the Product throughout the Licensed
Territory to the extent Allos is then performing or having performed such
activities, including assigning or amending as appropriate, upon request of
Mundipharma, any agreements or arrangements with Third Party vendors to Develop
the Product. To the extent that any such contract between Allos and a Third
Party is not assignable to Mundipharma, Allos shall reasonably cooperate with
Mundipharma to arrange to continue to provide such services for a reasonable
time after termination; and

        (iii)    Assumption of PDX License Agreement.    Provided that
Mundipharma is not in breach of this Agreement on the effective date of
termination of this Agreement pursuant to Section 12.4(d), in exercising its
rights under Section 12.6(c)(y), Mundipharma will assume all rights and
responsibilities of Allos under the PDX License Agreement, including the
royalties, milestones and sublicense fees provisions [*], to the extent
applicable to the rights granted to Mundipharma under this Agreement (i.e., in
respect of the Licensed Territory only).

not affect rights or obligations of the Parties under this Agreement that have
accrued prior to the date of termination or expiration. Notwithstanding anything
to the contrary, the following provisions shall survive any expiration or

contained in the following surviving Articles and Sections), 10, 11 (other than
Section 11.3) and 13 (other than Section 13.2); (ii) Sections 2.4, 4.10 (for a

claim arising out of or relating to the validity, construction, interpretation,
enforceability, breach, performance, application or termination of this
Agreement that is not resolved pursuant to Section 13.2 or by the Parties

[*] period described above, then the Executive Officer of Allos or Mundipharma,
as the case may be, shall have the unilateral right to cast the deciding vote
for the JSC as provided in Section 13.2(a) or 13.2(b). If neither Party has the
right to cast the deciding vote for the JSC pursuant to Section 13.2(a) or
13.2(b) (e.g., where Section 13.2(a) or 13.2(b) provides for exceptions to the
Executive Officer's right to make the final decision), then either Party may
submit the dispute for resolution pursuant to Section 13.1.

        (a)    Allos Decisions.    The Executive Officer of Allos shall have the
right to make the final decision with respect to: (i) any decision regarding
Development of the Product for the Field in the Allos Territory (except for a
decision involving an Additional Study other than an Allos Study) or an
Incremental Study being conducted by Allos, except where Mundipharma reasonably
believes either that such decision poses a substantial and unwarranted safety
risk (a "Safety Reason") or that such decision is substantially likely to cause
a Material Impact; (ii) prior to the Transfer Date, any decision regarding
Regulatory Materials with respect to the Product in the Field in the EEA or
communicating with Regulatory Authorities in the EEA to obtain or maintain
Regulatory Approval in the Field in the EEA, except where Mundipharma reasonably

decision regarding Development of the Product for the Field in the Licensed
Territory (except for a decision involving an Additional Study or a decision

        13.3    Equitable Relief.    Notwithstanding Sections 13.1 and 13.2,
each Party acknowledges that its breach of Article 11 may cause irreparable harm
to the other Party, which cannot be reasonably or adequately compensated by
damages in an action at law. By reason thereof, each Party agrees that the other
Party shall be entitled, in addition to any other remedies it may have under
this Agreement or otherwise, to seek preliminary and permanent injunctive and
other equitable relief from any state or federal court of competent jurisdiction
in New York, New York to prevent or curtail any actual or threatened breach of
Article 11 that is reasonably likely to cause it irreparable harm. In addition,
notwithstanding Sections 13.1 and 13.2, to the fullest extent provided by Law,
either Party may bring an action in any court of competent jurisdiction for
injunctive relief (or any other provisional remedy) to protect a Party's rights
or enforce a Party's obligations under this Agreement pending final resolution
of any claims related thereto pursuant to the dispute resolution procedure set
forth in Section 13.1.

        13.4    Governing Law.    This Agreement and all disputes arising out of
or related to this Agreement or any breach hereof shall be governed by and
construed under the laws of the State of New York, without giving effect to any
choice of law principles that would require the application of the laws of a
different state.

any dispute, controversy or claim relating to the scope, validity,
enforceability or infringement of any Patent or trademark rights outside the
U.S. covering the manufacture, use, importation, offer for sale or sale of the
Product shall be submitted to a court of competent jurisdiction in the country
in which such Patent or trademark rights were granted or arose.

        14.1    Entire Agreement; Amendment.    This Agreement, including the
Exhibits hereto, together with the Development Plan, the Supply Agreement, the
Consent, the Letter Agreement, the Pharmacovigilance Agreement and the Technical
Agreement, sets forth the complete, final and exclusive agreement and all the
covenants, promises, agreements, warranties, representations, conditions and
understandings between the Parties hereto with respect to the subject matter
hereof and supersedes, as of the Effective Date, all prior and contemporaneous
agreements and understandings between the Parties with respect to the subject
matter hereof. There are no covenants, promises, agreements, warranties,
representations, conditions or understandings, either oral or written, between
the Parties with respect to the subject matter of this Agreement other than as
are set forth in this Agreement, the Development Plan, the Supply Agreement, the
Pharmacovigilance Agreement and the Technical Agreement. No subsequent
alteration, amendment, change or addition to this Agreement shall be binding
upon the Parties unless reduced to writing and signed by an authorized officer
of each Party.

        14.2    Force Majeure.    Both Parties shall be excused from the
performance of their obligations under this Agreement to the extent that such
performance is prevented by force majeure and the non-performing Party promptly
provides notice of the prevention to the other Party. Such excuse shall continue
for so long as the condition constituting force majeure continues and the
non-performing Party takes reasonable efforts to remove the condition. For
purposes of this Agreement, force majeure shall include conditions beyond the
control of the Parties, including an act of God, war, civil commotion, terrorist
act, epidemic, failure or default of public utilities or common carriers,
destruction of production facilities or materials by fire, earthquake, storm or

could not have been prevented by the exercise of skill, diligence, and prudence
that would be reasonably and ordinarily expected from a skilled and experienced
person engaged in the same type of undertaking under the same or similar
circumstances). Notwithstanding the foregoing, a Party shall not be excused from
making payments owed hereunder because of a force majeure affecting such Party.
If a force majeure persists for more than ninety (90) days, then the Parties
will discuss in good faith the modification of the Parties' obligations under
this Agreement in order to mitigate the delays caused by such force majeure.

Mundipharma International Corporation Limited (Mundipharma) today jointly
announced that the companies have entered into a strategic collaboration
agreement to co-develop FOLOTYN® (pralatrexate injection). Under the agreement,
Allos retains full commercialization rights for FOLOTYN in the United States and
Canada, with Mundipharma having exclusive rights to commercialize FOLOTYN in all
other countries.

FOLOTYN, a folate analogue metabolic inhibitor, is the first and only drug
approved in the United States for the treatment of patients with relapsed or
refractory peripheral T-cell lymphoma (PTCL), a biologically diverse group of
aggressive blood cancers, and is being studied in a number of other hematologic
malignancies. Allos is pursuing regulatory approval to market FOLOTYN in the
European Union for relapsed or refractory PTCL. Allos' Marketing Authorisation
Application (MAA) was accepted for review by the European Medicines Agency (EMA)
in December 2010.

Under the collaboration, Allos will receive an upfront payment of $50 million
and potential regulatory and commercial progress- and sales-dependent milestone
payments of up to $310.5 million. Allos is also entitled to receive tiered
double-digit royalties based on net sales of FOLOTYN within Mundipharma's
licensed territories.

Allos and Mundipharma will jointly fund development costs, initially on a 60:40
basis, which will change to a 50:50 basis if certain pre-defined milestones are
achieved, including approval of the MAA currently under review to market FOLOTYN
in the European Union. Development funding by Mundipharma will support jointly
agreed-upon clinical development activities, including, but not limited to, the
planned Phase 3 studies of FOLOTYN in previously undiagnosed PTCL and in
combination with bexarotene in relapsed or refractory cutaneous T-cell lymphoma
(CTCL). Pursuant to a separate supply agreement with Mundipharma Medical
Company, an affiliate of Mundipharma, Allos will supply FOLOTYN for
Mundipharma's clinical and commercial uses.

"Mundipharma is an ideal global partner. They have demonstrated
hematology/oncology development, regulatory and commercial capabilities with
recent major regulatory and commercial successes in bringing Levact®
(bendamustine) to market in Europe for non-Hodgkin lymphoma and other blood
cancers, as well as substantial resources to develop and commercialize FOLOTYN,"
said Paul L. Berns, president and chief executive officer of Allos
Therapeutics, Inc. "We are currently seeking regulatory approval to market
FOLOTYN in Europe for the treatment of patients with relapsed or refractory
peripheral T-cell lymphoma. Our two companies share a vision for bringing
FOLOTYN to patients and believe this collaboration will maximize the
development, commercialization and market potential of FOLOTYN in a variety of
blood cancers."

"Mundipharma is delighted to partner with Allos in the development and
commercialisation of FOLOTYN and believes that it has worldwide potential to
become an important treatment alternative for patients," commented Åke Wikström,
regional director Europe at Mundipharma International Limited. "FOLOTYN
represents a very meaningful addition to Mundipharma's oncology pipeline and
reinforces our commitment to improving patients' quality of life."

"Lymphoma arising from T-lymphocytes remains a devastating disease and new
treatments are urgently needed. FOLOTYN, if approved, may be in many countries
the first drug to treat this cancer and this will allow us to work with
haematologists to improve the treatment results by developing new and hopefully
even more effective drug combinations," added Dr. Thomas Mehrling, director of
European Oncology at Mundipharma International Limited.

About FOLOTYN

FOLOTYN, a folate analogue metabolic inhibitor, was discovered by

developed by Allos Therapeutics. In September 2009, the U.S. Food and Drug
Administration (FDA) granted accelerated approval for FOLOTYN for use as a
single agent for the treatment of patients with relapsed or refractory PTCL.
This indication is based on overall response rate. Clinical benefit such as
improvement in progression-free survival or overall survival has not been
demonstrated. FOLOTYN has been available to patients in the U.S. since October
2009. An updated analysis of data from PROPEL was published in the March 20,
2011 issue of the Journal of Clinical Oncology.

FDA's accelerated approval program allows the FDA to approve products for cancer
or other life-threatening diseases based on initial positive clinical data. In
connection with the accelerated approval, Allos is required to conduct
post-approval studies that are intended to verify and describe the clinical
benefit of FOLOTYN in patients with T-cell lymphoma. In March 2011, Allos
reached agreement with the FDA under its Special Protocol Assessment (SPA)
process for the design of Allos' Phase 3 clinical trial of FOLOTYN in patients
with previously undiagnosed PTCL. The study will seek to enroll newly diagnosed
patients with PTCL who have achieved a response following initial treatment with
a CHOP-based therapy.

Allos is also pursuing regulatory approval to market FOLOTYN in the European
Union for relapsed or refractory PTCL. Allos' MAA was accepted for review by the
EMA in December 2010.

About Peripheral T-Cell Lymphoma

T-cell lymphomas comprise a biologically diverse group of blood cancers that
account for approximately 10% to 15% of all cases of non-Hodgkin lymphomas
(NHL).(1-3) Allos estimates the current annual incidence of PTCL to be
approximately 5,900 patients in the U.S. and approximately 6,000-7,000 patients
in the top five European markets. The

outcome of patients with PTCL is poor and the majority of patients ultimately
have refractory disease to a variety of agents, including multi-agent
chemotherapy with CHOP (cyclophosphamide, doxorubicin, vincristine, and
prednisone) or CHOP-like regimens. The 5-year overall survival rate in these
patients is 25% to 40%, depending on sub-type.(4-5)
