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

 

It is anticipated that the milestones paid for * will be either $U.S. * (i.e.,
the sum of (d)+(e)), or $U.S. * (i.e., (f) alone), depending on *, but under no
circumstances will the total milestone payments for * include payment under all
three milestones nor exceed $U.S. *. 
 
     In no event shall any milestone set forth herein be payable more than once.
 
          3.2.2 Milestone Payments; Disputes. Geron shall notify AngioChem in
writing within thirty (30) days after the achievement of each milestone set
forth in Section 3.2.1, and shall make the appropriate milestone payment within
thirty (30) days after the achievement of such milestone. In the event that,
notwithstanding the fact that Geron has not given such a notice, AngioChem
believes any such milestone event has occurred, it shall so notify Geron in
writing and shall provide to Geron data, documentation or other information that
supports its belief. Any dispute under this Section 3.2.2 that relates to
whether or not a milestone event has been achieved shall be referred to, and
resolved by, the JDC (provided that Geron shall not have the right to resolve
the matter if the JDC does not reach a unanimous decision), and, if after good
faith efforts the resolution is not achieved by the JDC, shall be resolved in
accordance with the dispute resolution procedures set forth in Section 11.6.
 
     3.3 Royalties for Licensed Products.
 
          3.3.1 Annual Net Sales Thresholds; Royalty Levels Applicable to
Licensed Product Sales by Geron and US Sublicensees; Adjustments.
 
               3.3.1.1 Subject to the terms and conditions of this Agreement,
royalties shall be due and payable by Geron to AngioChem on Net Sales of
Licensed Products by Geron or an Affiliate of Geron anywhere in the Territory
and Net Sales by any US Sublicensee in the U.S., calculated on a Licensed
Product-by-Licensed Product basis, in accordance with the Annual Net Sales
thresholds and royalty rates set forth in this Section 3.3.1. For example,
assuming Royalty B applies, in any Calendar Year Geron shall pay to AngioChem a
royalty of *% for the portion of Net Sales up to and including $*, a royalty of
*% for the portion of Net Sales exceeding $* and up to and including $*, and a
royalty of *% for the portion of Net Sales exceeding $*. For the avoidance of
doubt, no more than one royalty shall be due with respect to the same unit of
Licensed Product, and no royalty shall be due upon the sale, or other transfer,
among Geron and its Related Parties, but in such cases the royalty shall be due
and calculated based upon Geron’s or its Related Parties’ Net Sales to the first
Third Party other than a Sublicensee.
 
          (A) Royalty A. Royalties at the level set forth below under the column
entitled “Royalty A” shall apply for a Calendar Year if the actual Cost of
Goods/Average Sales Price Ratio of the applicable Licensed Product for such
Calendar Year exceeds * percent (*%).

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

 

          (B) Royalty B. Royalties at the level set forth below under the column
entitled “Royalty B” shall apply for a Calendar Year if the actual Cost of
Goods/Average Sales Price Ratio of the applicable Licensed Product for such
Calendar Year is greater than * percent (*%) but less than or equal to * percent
(*%).
 
          (C) Royalty C. Royalties at the level set forth below under the column
entitled “Royalty C” shall apply for a Calendar Year if the actual Cost of
Goods/Average Sales Price Ratio of the applicable Licensed Product for such
Calendar Year is equal to or less than * percent (*%).
 

Annual Net Sales Royalty A Royalty B Royalty C Thresholds       ≤$* * % * % * %
>$* - ≤$* * % * % * % >$* * % * % * %

               3.3.1.2 For the first Calendar Year in which a Licensed Product
is sold, the applicable royalty rates and royalty payments shall be calculated
using a Preliminary Cost of Goods/Average Sales Price Ratio equal to * percent
(*%) and Royalty B shall apply. For each Calendar Year thereafter the applicable
royalty rates and royalty payments shall be calculated using a Preliminary Cost
of Goods/Average Sales Price Ratio equal to the Adjusted Cost of Goods/Average
Sales Price Ratio for the preceding Calendar Year. For each Calendar Year,
royalties shall be calculated and paid for each Calendar Quarter based on such
Preliminary Cost of Goods/Average Sales Price Ratio. The Adjusted Cost of
Goods/Average Sales Price Ratio for each Calendar Year shall be determined based
on the Adjusted Cost of Goods and Adjusted Average Sales Price for such Calendar
Year reported by Geron pursuant to Section 1.18 and Section 1.8, respectively,
within ninety (90) days after the end of each Calendar Year. If it is
determined, based on such Adjusted Cost of Goods/Average Sales Price Ratio, that
a different royalty rate would apply, then (i) if Geron paid to AngioChem
royalties in excess of the royalties due based on such Adjusted Cost of
Goods/Average Sales Price Ratio, any such excess shall be credited against the
next royalty payment(s) due to AngioChem, or (ii) if Geron owes an additional
royalty payment to AngioChem based on such Adjusted Cost of Goods/Average Sales
Price Ratio, Geron shall make such additional payment within thirty (30) days
after the date of such determination, or as otherwise agreed upon in writing by
the Parties. By way of example only, the Adjusted Average Sales Price and
Adjusted Cost of Goods for a Licensed Product for Calendar Year 2013 would be
utilized to determine the Preliminary Cost of Goods/Average Sales Price Ratio
applicable to sales of such Licensed Product made in Calendar Year 2014, and
quarterly royalty payments would be made on that basis. In the event the
Adjusted Average Sales Price or Adjusted Cost of Goods for a Licensed Product
for Calendar Year 2013 does not equal the Adjusted Average Sales Price or
Adjusted Cost of Goods for a Licensed Product in Calendar Year 2014, the
Adjusted Cost of Goods/Average Sales Price Ratio would be calculated and
adjustment payments would be made as set forth above.

               3.3.1.3 In the event that Geron is unable to determine the Cost
of Goods incurred by a U.S. Sublicensee in any Calendar Year, the applicable
royalty rate to be paid by Geron on Net Sales of Licensed Products by such US
Sublicensee in the U.S. in such Calendar Year will be as set forth under the
column entitled “Royalty B” in Section 3.3.1.1.
 
          3.3.2 Reduction In Annual Net Sales Thresholds. In the event that
sales of Licensed Products are made by any Sublicensee in Europe and/or Japan,
the Annual Net Sales thresholds set forth above shall be reduced, in an additive
fashion, by the following percentages, and such reduced Annual Net Sales
thresholds shall be applied to determine the percentage royalty due by Geron on
Net Sales of Licensed Products sold by Geron, its Affiliates and U.S.
Sublicensees:
 
          (A) Annual Net Sales thresholds shall be reduced by * percent (*%) in
the event that sales of Licensed Products are made by a Sublicensee in Europe;
and
 
          (B) Annual Net Sales thresholds shall be reduced by * percent (*%) in
the event that sales of Licensed Products are made by a Sublicensee in Japan.
 
          For example, (1) if sales of Licensed Products are made by a
Sublicensee in Japan, but sales of Licensed Products are made by Geron or a
Geron Affiliate in Europe, then the Annual Net Sales thresholds will be: ≤$*;
>$* - ≤$*; and >$*; (2) if sales of Licensed Products are made by a Sublicensee
in Europe, but sales of Licensed Products are made by Geron or a Geron Affiliate
in Japan, then the Annual Net Sales thresholds will be: ≤$*; >$* - ≤$*: and >$*,
and (3) if sales of Licensed Products are made by one or more Sublicensees in
Japan and Europe, but sales of Licensed Products are made by Geron or a Geron
Affiliate outside of Japan and Europe, then the Annual Net Sales thresholds will
be: ≤$*; >$* - ≤$*: and >$*. For the avoidance of doubt, there shall be no
reduction in Annual Net Sales thresholds in the event that sales of Licensed
Products are made by a Sublicensee outside of Europe and Japan. Furthermore, in
no event shall any reduction in Annual Net Sales thresholds made pursuant to
this Section 3.3.2 exceed * percent (*%) of the Annual Net Sales thresholds that
would otherwise be applicable pursuant to Section 3.3.1 to Net Sales of Licensed
Products by Geron.
 
          3.3.3 Combination Products. In determining Net Sales of any
Combination Products under this Agreement in any country, Net Sales shall first
be calculated in accordance with the definition of “Net Sales”, and the
resulting figure shall then be multiplied by the percentage value of the
Licensed Product contained in the Combination Product, such percentage value
being the quotient obtained by dividing the current market price of the Licensed
Product by the sum of the separate current market price of the Licensed Product
in such country and the other active pharmaceutical ingredients contained in the
Combination Product in such country. The current market price of each active
pharmaceutical ingredient and of the Licensed Product shall be for a comparable
quantity sold in such country to that contained in the Combination Product and
of the same class, purity and potency. When no current market price is available
for any active pharmaceutical ingredients or for the Licensed Product in such
country, the Parties shall agree in good faith upon a hypothetical market price
with respect to the Combination Product, allocating the same proportions of
costs, overhead and profit as are then allocated to all similar substances then
being made and marketed by Geron and having an ascertainable market price in
such country or upon such other basis as the Parties may agree; provided,
however, that if the Parties are unable to agree upon such hypothetical market
price, the Parties shall submit the matter promptly for resolution in accordance
with Section 11.6.

          3.3.4 Royalty Stacking. On a country-by-country basis, if, in any
Calendar Year, Geron, any Geron Affiliate or any US Sublicensee with respect to
sales in the U.S., or Geron or any Geron Affiliate with respect to sales in
Europe, makes payment(s) to one or more Third Parties in order to obtain or
maintain license rights necessary to develop, make, have made, use, offer to
sell, sell, import and otherwise commercialize Licensed Products in a country,
Geron, its Affiliates or such Sublicensees shall be entitled to deduct * percent
(*%) of such payment(s) from royalty payments otherwise payable by Geron to
AngioChem for sales in such country. Notwithstanding the foregoing, in no event
shall such deduction exceed * (*%) of the royalties otherwise payable to
AngioChem with respect to such country in such Calendar Year.
 
          3.3.5 Compulsory Licenses. If a Compulsory License for any country is
granted to a Third Party other than a Sublicensee, then the royalty to be paid
by Geron, its Affiliate or Sublicensee to AngioChem with respect to sales by
such Third Party in such country shall be * percent (*%) of all amounts paid by
the compulsory licensee to Geron, its Affiliate or Sublicensee, including
without limitation, upfront payments, milestones, royalties and share of
Sublicense Revenue, regardless of Annual Net Sales thresholds or Adjusted Cost
of Goods/Average Sales Price Ratio.
 
     3.4 Milestone Payments and Royalties Applicable to Licensed Product Sales
by Sublicensees.
 
          3.4.1 Sales by US Sublicensees in the United States. If Geron grants a
sublicense to a Sublicensee to develop, make, have made, use, offer to sell,
sell, import or otherwise commercialize Licensed Products in the United States
(a “US Sublicensee”), milestone payments shall be due and payable by Geron as
set forth in Section 3.2.1 upon achievement of such milestones by such US
Sublicensee as if such milestones had been achieved by Geron, and royalties
shall be due on Net Sales of Licensed Products by such US Sublicensee as set
forth in Section 3.3.1 as if the sales of such Licensed Products had been made
by Geron, including in the calculation of royalty rates based on the Preliminary
Cost of Goods/Average Sales Price Ratio and Adjusted Cost of Goods/Average Sales
Price Ratio with respect to sales in the United States by, and Preliminary Cost
of Goods and Adjusted Cost of Cost of Goods with respect to sales in the United
States of, the US Sublicensee, and the determination of the applicable Annual
Net Sales threshold shall be based on Net Sales by Geron and its Affiliates and
the Net Sales in the United States by the US Sublicensee.

          3.4.2 Sales by Sublicensees in the Rest of World. If Geron grants a
sublicense to a Sublicensee to develop, make, have made, use, offer to sell,
sell, import or otherwise commercialize Licensed Products in any country in the
Rest of World (each, a “Sublicensed Country”), Geron shall pay to AngioChem a
share of any Sublicense Revenue received from such Sublicensee. The share of
such Sublicense Revenue shall vary depending upon the stage of development of
the Licensed Product that is sublicensed at the time that the sublicense is
granted for such Sublicensed Country, as follows:
 
          (A) If the sublicense is granted by Geron for a Licensed Product prior
to obtaining the first Marketing Authorization in the U.S. for such Licensed
Product, Geron shall pay to AngioChem an amount equal to * percent (*%) of such
Sublicense Revenue.
 
          (B) If the sublicense is granted by Geron for a Licensed Product after
obtaining the first Marketing Authorization in the U.S. for such Licensed
Product, Geron shall pay to AngioChem an amount equal to * percent (*%) of such
Sublicense Revenue.
 
     3.5 Option to Buy-Out/Buy-Down the Agreement Economics; Fixed Royalty
Option.
 
          3.5.1 Buy-Out/Buy-Down Option.
 
          (A) AngioChem hereby grants to Geron an option to negotiate terms of
an agreement to eliminate or reduce the milestones, royalties and share of
Sublicense Revenue payable by Geron to AngioChem pursuant to Sections 3.3 and
3.4 of this Agreement (the “Buy-Out/Buy-Down Option”). The Buy-Out/Buy-Down
Option shall be exercisable by provision of written notice to AngioChem by Geron
and the term of the Buy-Out/Buy-Down Option shall run from the Effective Date up
to and including the date of *. Following exercise of the Buy-Out /Buy-Down
Option, the Parties shall negotiate in good faith, for a period of * (*) days or
such longer period as the Parties may agree (the “Negotiation Period”), an
agreement to eliminate or reduce the milestones, royalties and share of
Sublicense Revenues payable under this Agreement, or some combination thereof,
in exchange for consideration from Geron (the “Buy-Out/Buy Down Consideration”).
Any mutually acceptable modified economic terms for such Buy-Out/Buy-Down Option
shall be set forth in a written amendment to this Agreement executed by the
Parties. Failure of the Parties to agree on mutually acceptable modified
economic terms in the Negotiation Period shall not be a breach of this
Agreement. The Buy-Out/Buy-Down Option shall expire if the Parties do not reach
agreement during the Negotiation Period and Geron shall have no further rights
(and AngioChem shall have no further obligation) pursuant to this Section 3.5.
 
          (B) Commencing on the Effective Date and for a period of * (*) days
thereafter, the Parties shall negotiate diligently and in good faith to
establish mutually acceptable Buy-Out/Buy-Down Consideration that would be
payable by Geron to AngioChem following exercise of the Buy-Out/Buy-Down Option.
Each Party agrees to cooperate with reasonable requests made by the other Party
to undertake such negotiations and agrees to exercise good faith efforts to
conclude such negotiations with the establishment of mutually acceptable terms
for the Buy-Out/Buy-Down Option. Failure of the Parties to establish mutually
acceptable terms in such ninety day period shall not be a breach of this
Agreement and shall not extinguish the Buy-Out/Buy-Down Option.

          3.5.2 Fixed Royalty Option. In addition to the Buy-Out/Buy-Down Option
set forth in Section 3.5.1, Geron shall have an option, for a period of * (*)
days after the Effective Date, to elect to amend the terms and conditions of
this Agreement with respect to the royalties due on sales by US Sublicensees to
provide for payment by Geron to AngioChem of a fixed royalty of * percent (*%)
on Net Sales of Licensed Products made by such US Sublicensees (the “Royalty
Reduction Option”). In consideration of any such amendment, Geron shall make an
additional cash payment to AngioChem in the amount of * dollars ($*) (the
“Royalty Reduction Consideration). There will be no change in the milestones
payable under 3.4.1. If Geron, in its sole discretion, elects to exercise the
Royalty Reduction Option, it shall notify AngioChem in writing within * (*) days
after the Effective Date, and the Parties shall promptly amend this Agreement in
writing to reflect the foregoing terms. Upon execution of such amendment, the
calculation of royalty rates based on the Preliminary Cost of Goods/Average
Sales Price Ratio and Adjusted Cost of Goods/Average Sales Price Ratio will no
longer include sales in the United States by, and Preliminary Cost of Goods and
Adjusted Cost of Cost of Goods will no longer include sales in the United States
of, the US Sublicensee. Payment by Geron of the Royalty Reduction Consideration
shall be due within five (5) business days after execution of such amendment.
 
     3.6 Reports; Payment of Royalty. Following the First Commercial Sale of a
Licensed Product, Geron shall furnish to AngioChem a written report for each
Calendar Quarter showing (i) the Net Sales of all Licensed Products sold by
Geron, (ii) Net Sales of Licensed Products by US Sublicensees, (iii) Sublicense
Revenues received by Geron on account of sublicenses granted pursuant to this
Agreement in any country in the Rest of World during the reporting period, (iv)
payments received from compulsory licensees as set forth in Section 3.3.5 (if
any), and (v) the royalties and/or share of Sublicense Revenue and payments from
compulsory licensees (if any) payable under this Agreement. Such reports shall
be due sixty (60) days following the close of each Calendar Quarter until
expiration or termination of this Agreement. Royalties on Net Sales, share of
Sublicense Revenue and payments from compulsory licensees received by Geron
shall be due and payable on the date such royalty report is due. Geron shall
keep complete and accurate records in sufficient detail to enable the royalties
and other amounts payable hereunder to be determined.
 
     3.7 Audits.
 
          3.7.1 Upon the written request of AngioChem made not more than once in
each Calendar Year, Geron shall permit an independent certified public
accounting firm of nationally recognized standing selected by AngioChem and
reasonably acceptable to Geron, at AngioChem’s expense, to have access during
normal business hours to such of the records of Geron and its Affiliates as may
be reasonably necessary to verify the accuracy of Geron’s royalty reports,
including, without limitation, the calculation of share of Sublicense Revenue,
payments from compulsory licensees (if any), Net Sales, Cost of Goods and
Average Sales Price set forth therein. Any such audit shall be commenced within
twenty-four (24) months after the end of the Calendar Year to which the royalty
report to be audited pertains, and shall be completed by the delivery of a
written report setting forth the audit findings within a reasonable time, but no
more than one hundred and twenty (120) days after commencement of the audit
unless the independent certified public accounting firm advises the Parties in
writing that it is unable to complete the audit as a result of Geron’s failure
to provide requested information which is in Geron’s possession or delays caused
by Geron, and specifically identifies information which has not been made
available, or provides examples of delay. The accounting firm shall disclose to
AngioChem only whether the royalty reports, including the calculated Net Sales,
the calculated Cost of Goods, calculated Average Sales Price and the calculation
of share of Sublicense Revenue and payments from compulsory licensees, are
correct or incorrect, and the amount of any discrepancy between the amount
calculated by Geron and the amount calculated by the accounting firm based upon
the audit. A copy of the accounting firm’s findings shall also be provided to
Geron.

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

 

          3.7.2 If the accounting firm identifies a discrepancy made during the
applicable reporting period that has resulted in an underpayment or overpayment
of royalties, share of Sublicense Revenue or payments from compulsory licensees,
then unless the audit findings are disputed by a Party (in which case such
dispute shall be submitted to arbitration pursuant to Section 11.6) (i) if Geron
owes an additional payment to AngioChem, Geron shall pay the amount of the
discrepancy to AngioChem within thirty (30) days of the date the accounting firm
provides its findings, or as otherwise agreed upon by the Parties and (ii) if
AngioChem owes a payment to Geron, Geron may credit the amount of the
discrepancy against the next royalty payment(s) due to AngioChem. The fees
charged by such accounting firm shall be paid by AngioChem; provided, however,
that if such audit uncovers an underpayment of royalties, share of Sublicense
Revenue or payments from compulsory licensees by Geron that exceeds * percent
(*%) of the total amount owed, then the fees of such accounting firm shall be
paid by Geron.
 
          3.7.3 Upon the expiration of twenty-four (24) months following the
receipt by AngioChem of the royalty report for the fourth Calendar Quarter of
each Calendar Year, unless an audit has been commenced, the calculation of Net
Sales, the Cost of Goods, Average Sales Price, royalties, share of Sublicense
Revenue and payments from compulsory licensees payable hereunder for such
Calendar Year shall be binding and conclusive upon AngioChem, Geron, its
Affiliates and Sublicensees, and Geron, its Affiliates and Sublicensees shall be
released from any liability or accountability with respect to royalties for such
year.
 
          3.7.4 AngioChem shall treat all financial information subject to
review under this Section 3.6 or under any sublicense agreement in accordance
with the confidentiality and non-use provisions of this Agreement, and shall
cause its accounting firm to enter into a confidentiality agreement with
AngioChem no less restrictive than the terms set forth in Section 7.1 hereof.

     3.8 Payment Exchange Rate. All payments to be made by Geron to AngioChem
under this Agreement shall be made in United States dollars and may be paid by
bank wire transfer in immediately available funds to such bank account in Canada
as may be designated in writing by AngioChem from time to time. In the case of
sales of Licensed Products outside the United States, the rate of exchange to be
used in computing the monthly amount of currency equivalent in United States
dollars due AngioChem shall be made at the monthly rate of exchange utilized by
Geron in its accounting system, prevailing on the last business day of the month
preceding the month in which such sales are recorded by Geron.
 
     3.9 Income Tax Withholding. If laws, rules or regulations require
withholding of income taxes or other taxes imposed upon payments set forth in
this Article 3, Geron shall make such withholding payments as may be required
and shall subtract such withholding payments from the payments due to AngioChem
set forth in this Article 3. Geron shall deliver to AngioChem a proof of payment
within a reasonable period of time after making such withholding payment. Geron
shall promptly provide AngioChem with the official receipts received by Geron of
any such withholding payment. Geron shall, at AngioChem’s expense, provide
AngioChem reasonable assistance in order to allow AngioChem to obtain the
benefit of any present or future treaty against double taxation which may apply
to such payments.
 
     3.10 Overdue Royalties and Milestones. All royalty payments not made within
the time period set forth in Section 3.5 or milestone payments not made within
the time period set forth in Section 3.2.2, including underpayments discovered
during an audit, shall bear interest at a rate of * percent (*%) per month from
the due date until paid in full or, if less, the maximum interest rate permitted
by Applicable Laws. Any such overdue royalty or milestone payment shall, when
made, be accompanied by, and credited first to, all interest so accrued. Payment
by Geron of any such overdue royalty or milestone payment, plus interest as set
forth herein, shall fully and finally extinguish any claims which are or might
have been made by AngioChem as a result of such overdue royalty or milestone
payment.

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

 

     4.2 Joint Development Committee.
 
          4.2.1 Establishment of the Joint Development Committee. Promptly after
the Effective Date, the Parties shall establish a joint development committee
(the “JDC”) to oversee clinical development of ANG1005. Unless otherwise agreed
between the Parties, the JDC shall remain in effect from the Effective Date of
this Agreement up to and including the First Commercial Sale of a Licensed
Product containing ANG1005 and as long thereafter as any activities are being
conducted under the Clinical Development Plan or a subsequent clinical
development plan for a Further Licensed Product or any earlier termination of
this Agreement.
 
          4.2.2 Tasks of the Joint Development Committee. The principal purpose
of the JDC shall be to provide a forum for open communication between the
Parties with respect to the clinical development of Licensed Products containing
ANG1005, and for AngioChem to act in an advisory and consultative capacity with
respect to the Clinical Development Plan. The JDC shall make recommendations
regarding the overall strategy for the Clinical Development Plan. Geron shall
inform the JDC of proposed material amendments to the Clinical Development Plan,
in order to permit the JDC to provide advice, guidance, direction and other
recommendations with respect to the Clinical Development Plan. Subject to the
express rights of the Parties as set forth herein, the functions of the JDC
shall include:
 
          (A) Acting as liaison between the Parties to ensure open and regular
communication channels, and more particularly to ensure that the Parties are
informed of, and have a forum to discuss, the ongoing progress of the Clinical
Development Plan;
 
          (B) Reviewing and recommending (or declining to recommend) proposed
material amendments to the Clinical Development Plan;
 
          (C) Reviewing, consulting on and providing input with respect to
activities related to the manufacturing of Licensed Products containing ANG1005
and the selection of manufacturer(s) of such Licensed Products, provided final
control of such activities shall remain with Geron, and that such consultation
and input shall not in any way delay any negotiation or completion of
manufacturing arrangements that Geron may wish to establish with respect to
Licensed Products;
 
          (D) Reviewing, discussing and evaluating data, results and information
concerning the AngioChem Technology, including any Angiopep, that might
reasonably be useful to Geron for the research, development and/or
commercialization of a Licensed Product under this Agreement; provided, however,
that AngioChem shall not be required to disclose any patentable AngioChem
Technology (including without limitation any Angiopep) until AngioChem has filed
a patent application with respect thereto; and
 
          (E) Performing such other activities and discharging such other
responsibilities as may be assigned to the JDC by the Parties pursuant to this
Agreement or as may be mutually agreed upon by the Parties from time to time.
 
For the avoidance of doubt, the JDC will not have any power to amend this
Agreement.
 
22
 

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

 

          4.2.3 Composition of the Joint Development Committee. The JDC shall be
comprised of three (3) representatives of AngioChem and three (3)
representatives of Geron. Each Party may change its representatives to the JDC
from time to time, in its sole discretion, effective immediately upon prior
written notice to the other Party of such change. JDC representatives shall have
appropriate technical credentials, experience and knowledge, and ongoing
familiarity with ANG1005 and other Licensed Products containing ANG1005 to
participate meaningfully in decisions made by JDC. Additional representatives or
consultants may from time to time, by mutual consent of the Parties, be invited
to attend JDC meetings, subject to such representative’s or consultant’s written
agreement to comply with the confidentiality obligations set forth in Section
7.1. The JDC shall be chaired by a representative of Geron. The JDC shall strive
to reach unanimous agreement on any decisions to come before it, but in the
event that the JDC cannot or does not, after good faith efforts, reach unanimous
agreement, the resolution and/or course of conduct shall be determined by Geron,
in its sole discretion; provided, however, that Geron’s right to resolve a
decision if the JDC does not reach a unanimous approval shall not apply to any
dispute that relates to whether or not a milestone event has been achieved,
which shall be submitted to dispute resolution in accordance with Section 11.6.
Each Party shall bear its own expenses related to the attendance of JDC meetings
by its representatives.
 
          4.2.4 Joint Development Committee Meetings. The JDC will meet once
every Calendar Quarter unless otherwise agreed in writing by the Parties.
Meetings may be held in person or by means of telecommunication (telephone,
video, or web conferences); provided, however, that the Parties will strive to
hold at least one (1) meeting per year in person. The JDC may meet more
frequently by agreement of the Parties. Each Party shall ensure that its
representatives to the JDC are reasonably available to attend and participate in
regularly scheduled JDC meetings, as well as any ad hoc JDC meetings that a
Party may request. Geron will be responsible for organizing the meetings of the
JDC and for distributing the agenda of the meetings, unless otherwise agreed.
Geron will include on the agenda any item within the scope of the responsibility
of the JDC that is requested to be included by any member of the JDC, and will
distribute the agenda and any accompanying information and materials to be
presented at the meeting to the JDC sufficiently in advance of the meeting to
permit meaningful review. A representative of Geron will prepare the meeting
minutes promptly after each meeting, and will send such minutes and any
materials presented at the meeting that were not distributed in advance of the
meeting to all members of the JDC for review and approval. Minutes will be
deemed approved unless any member of the JDC objects to the accuracy of such
minutes by providing written notice to the other members of the JDC within
fourteen (14) business days after receipt of the minutes. In the event of any
such objection that is not resolved by mutual agreement of the Parties, such
minutes will be amended to reflect such unresolved objection.
 
     4.3 Development of Further Licensed Products.
 
          4.3.1 Joint Research Committee. If requested by Geron or, if Geron
requests and AngioChem agrees to perform research or preclinical development
activities pursuant to subclause (b) of Section 4.3.2, by AngioChem, the Parties
shall promptly establish a Joint Research Committee (the “JRC”) to oversee the
research and non-clinical development of Licensed Products other than Licensed
Products containing ANG1005. The decision to establish a JRC shall be at Geron’s
sole discretion. The composition of a JRC, if Geron requests that a JRC be
established, shall be determined by mutual agreement of the Parties, but it is
anticipated that the JRC shall be comprised of three (3) representatives of
AngioChem and three (3) representatives of Geron. The JRC shall be chaired by a
representative of Geron, and shall operate similarly to the JDC, provided that
the Parties shall mutually agree upon the specific tasks and scope of
responsibility of the JRC at such time as the JRC may be established. The JRC
shall strive to reach unanimous agreement on any decisions to come before it,
but in the event that the JRC cannot or does not, after good faith efforts,
reach unanimous agreement, the resolution and/or course of conduct shall be
determined by Geron, in its sole discretion. Each Party shall bear its own
expenses related to the attendance of JRC meetings by its representatives.

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

 

          4.3.2 Additional Research. In the event that Geron, its Affiliates and
Sublicensees cease the development or commercialization of all Licensed Products
containing ANG1005, and Geron, its Affiliates or Sublicensees elect to develop a
License Product other than a Licensed Product containing ANG1005 (a “Further
Licensed Product”), Geron shall provide written notice to AngioChem and prepare
and present to AngioChem a research plan for such Further Licensed Product and
any proposed material amendments to such research plan. If Geron ceases the
development or commercialization of such Further Licensed Product, Geron may
repeat this procedure for another Further Licensed Product, and as many Further
Licensed Products as Geron elects. Each such research plan, as initially
prepared by Geron, and as amended from time to time, shall (a) set forth the
research and development objectives, including pre-clinical studies, anticipated
clinical trials, anticipated regulatory filings and other activities and
timelines with reasonable specificity, and (b) if Geron wishes AngioChem to
conduct any research or pre-clinical development activities, set forth which
activities are proposed by Geron to be undertaken by AngioChem and the
approximate number of AngioChem personnel estimated by Geron to be required to
perform such activities, provided that AngioChem shall not be required to
undertake any activity unless AngioChem agrees in writing to undertake such
activity. If Geron requests that AngioChem perform any such activities with
respect to any Further Licensed Product, AngioChem shall promptly inform Geron
if it is willing perform such activities, and if so the Parties shall negotiate
in good faith to establish the terms and conditions of such performance,
including any budget with respect thereto. Geron shall keep AngioChem and the
JRC, if a JRC has been established, apprised with updates to the research plan
for each Further Licensed Product, which shall be prepared by Geron and provided
to AngioChem and the JRC, if a JRC has been established, for review. For
avoidance of doubt, the course of conduct with respect to any plan regarding
research and development of Further Licensed Products shall be determined by
Geron, in its sole discretion. Geron shall be responsible for all funding of
such research and development, including research and development conducted by
AngioChem pursuant to terms and conditions agreed by the Parties.
 
24
 

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

 

     4.4 Costs and Expenses. All costs and expenses incurred by Geron in the
exercise of the rights granted under this Agreement, including, without
limitation, the performance of the Clinical Development Plan, costs incurred in
research and development of Further Licensed Products and costs incurred by
Geron in connection with the operation of the JRC and the JDC, shall be borne
solely by Geron unless otherwise agreed in writing by the Parties.
 
     4.5 Diligence.
 
          4.5.1 Geron shall use Commercially Reasonable Efforts to perform the
activities set forth in the Clinical Development Plan with respect to a Licensed
Product containing ANG1005. Geron shall have an obligation to use Commercially
Reasonable Efforts to develop and commercialize only one Licensed Product, and
for so long as Geron is using Commercially Reasonable Efforts to develop and
commercialize a Licensed Product containing ANG1005, this diligence obligation
shall be satisfied. If, despite the exercise of Commercially Reasonable Efforts
to perform the activities set forth in the Clinical Development Plan, Geron, its
Affiliates and Sublicensees cease the development or commercialization of a
Licensed Product containing ANG1005 (as demonstrated by (a) written notice by
Geron to AngioChem that it has ceased such development, or (b) the cessation, by
Geron, its Affiliates and Sublicensees of the allocation of funds, personnel or
other resources to the continued development or commercialization of a Licensed
Product containing ANG1005 in accordance with the Clinical Development Plan for
a period of two (2) consecutive Calendar Quarters), then Geron shall use
Commercially Reasonable Efforts to develop and commercialize a Further Licensed
Product, including the provision of a research plan to AngioChem as specified in
Section 4.3.2 within thirty (30) days after delivery of notice by Geron under
subclause (a) of this Section, or the end of two (2) consecutive Calendar
Quarters of inactivity as described in subclause (b) of this Section. The
obligations of Geron with respect to any Licensed Product under this Section 4.5
are expressly conditioned upon the continuing absence of any adverse condition
or event relating to the safety or efficacy of the Licensed Product, and the
obligation of Geron to develop or market any such Licensed Product shall be
delayed or suspended so long as any such condition or event exists. If such an
adverse condition or event arises, Geron shall promptly inform AngioChem upon
becoming aware of such adverse condition or event, and the Parties shall make
reasonable efforts to promptly (and in any event within twenty (20) business
days) convene a JDC meeting. At such JDC meeting, Geron shall provide the JDC
with the details of such adverse condition or event and a description of actions
planned by Geron in good faith to resolve the cause of such delay or suspension.
 
          4.5.2 In the event that (i) Geron, its Affiliates and Sublicensees
cease the development or commercialization of a Licensed Product containing
ANG1005 (as demonstrated by (a) written notice by Geron to AngioChem that it has
ceased such development, or (b) the cessation, by Geron, its Affiliates and
Sublicensees of the allocation of funds, personnel or other resources to the
continued development or commercialization of a Licensed Product containing
ANG1005 in accordance with the Clinical Development Plan for a period of two (2)
consecutive Calendar Quarters), and (ii) either (x) Geron fails to deliver a
research plan as specified in Section 4.3.2 for a Further Licensed Product
within thirty (30) days after such notice or cessation; or (y) Geron delivers
such plan, but Geron, its Affiliates and Sublicensees cease the development or
commercialization of a Further Licensed Product (as demonstrated by (a) written
notice by Geron to AngioChem that it has ceased such development, or (b) the
cessation, by Geron, its Affiliates and Sublicensees of the allocation of funds,
personnel or other resources to the continued development or commercialization
of such Further Licensed Product in accordance with such research plan for a
period of two (2) consecutive Calendar Quarters), and does not deliver a
research plan as specified in Section 4.3.2 for another Further Licensed Product
within thirty (30) days after such notice or cessation, then AngioChem may
terminate this Agreement on written notice to Geron, and subject to Section
10.2.2, Section 4.5.3 shall apply.
 
25
 

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

 

          4.5.3 (i) If, despite its exercise of Commercially Reasonable Efforts
to develop a Licensed Product as set forth in Section 4.5.1, Geron elects to
terminate this Agreement pursuant to Section 10.3 and Geron is not in material
breach of this Agreement, or (ii) if AngioChem elects to terminate this
Agreement as set forth in Section 4.5.2 and provided that AngioChem is not in
material breach of this Agreement (provided that any dispute as to whether
either Party is or is not in material breach of this Agreement shall be subject
to arbitration under Section 12.6), the licenses granted by Geron in Section 2.4
shall survive, and Geron shall, upon request by AngioChem made within one
hundred eighty (180) days after the Section 4.5.3 End Date (as defined below),
and subject to (a) the terms and conditions of this Agreement, (b) sublicenses
granted to any Sublicensees whose sublicense survives termination in accordance
with Section 10.4.4, and (c) any other non-exclusive license or option rights
granted by Geron as of the effective date of termination, (x) grant to AngioChem
an exclusive, worldwide license to develop and commercialize Licensed Products
in the Field, including the right to grant sublicenses, under all Patent Rights
that claim a Licensed Product (or any component thereof) and Know-How Controlled
by Geron (including, without limitation, Geron’s interest in Joint Intellectual
Property) necessary or actually used by Geron at the time of termination for the
research, development and/or commercialization of Licensed Products (or any
component thereof) as single agents, in the Field, (y) shall promptly transfer
to AngioChem data, regulatory filings and technology as set forth in Section
10.4.2, and (z) comply with the provisions of Section 10.3 with respect to human
clinical trials. In consideration of the foregoing grant of license and transfer
of data, regulatory filings and technology by Geron to AngioChem, Geron shall be
entitled to receive royalties in the amount of * percent (*%) of Net Sales of
Licensed Products by AngioChem, its Affiliates and any sublicensees of AngioChem
or its Affiliates greater than * dollars (U.S.$*) in any Calendar Year, until
such time as Geron has received an amount (the “Reimbursement Amount”)
determined by the following formula: *
 
     Within sixty (60) days following the Section 45.3 End Date, Geron will
advise AngioChem of Geron’s calculation of the Reimbursement Amount, together
with reasonable supporting details. If AngioChem disputes such calculation, the
matter will be resolved pursuant to Section 11.6. Notwithstanding the foregoing,
if, prior to termination under this Section 4.5.3, the Parties have executed a
written amendment to this Agreement setting forth mutually acceptable economic
terms payable under this Agreement after exercise by Geron of the
Buy-Out/Buy-Down Option pursuant to Section 3.5.1, then no payment shall be due
by AngioChem to Geron for the grant of the license and transfer of data,
regulatory filings and technology under this Section 4.5.3, including, without
limitation, payment of the Reimbursement Amount.

reasonably be requested by Geron to enable Geron to perform this function.
Notwithstanding the foregoing, if Geron elects not to file, prosecute or
maintain a Product Patent, it will promptly inform AngioChem in writing, and
AngioChem will have the right, but not the obligation, to file, prosecute or
maintain such Product Patent, in any country or countries, at its sole cost and
expense, using counsel of Geron’s choice.. In that case, at AngioChem’s request
and expense, Geron shall assist in filing, prosecuting and maintaining such
Product Patents in any and all countries by executing such applications,
specifications, oaths, and all other instruments which AngioChem shall deem
necessary in order to apply for and obtain such rights. The Parties shall agree
on a plan to file specific divisional, continuation or new patent applications
based on Technology Patents, which divisional, continuation or new patent
applications will be Product Patents as defined in Section 1.48, and shall
cooperate to effectuate the filings in accordance with such plan.

Geron and AngioChem will cooperate fully and will provide each other with any
information or assistance that either may reasonably request. Each Party shall
keep the other informed of developments in any such action or proceeding,
including, to the extent permissible by Applicable Law, consultation on any
settlement, the status of any settlement negotiations and the terms of any offer
related thereto. Neither Party shall settle any such interference, opposition,
reissue, or reexamination proceeding initiated by it without the prior written
consent of the other Party, which consent shall not be unreasonably withheld,
conditioned or delayed.
 
     6.2 Enforcement of Licensed Patents and Licensed Know-How.
 
          6.2.1 Notices. Each Party shall provide the other with notice of any
infringement or declaratory judgment action with respect to Licensed Patents or
misappropriation or misuse of Licensed Know-How that may come to its attention.
Upon receipt of any such notice, Geron and AngioChem shall thereafter consult
and cooperate fully to determine a course of action, including, but not limited
to, the commencement of legal action to terminate such infringement or
misappropriation.
 
          6.2.2 Product Patents. As between Geron and AngioChem, Geron shall

Product Patents. Geron shall keep AngioChem informed of
 
29
 

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

 

developments in any such action or proceeding, including consultation on any
settlement, the status of any settlement negotiations and the terms of any offer
related thereto. AngioChem shall cooperate fully in any such action, including,
without limitation, being named as a party plaintiff as necessary, and will
provide any information or assistance that Geron may reasonably request. In any
such action, Geron shall not knowingly take any position adverse to the issuance
or maintenance of any Technology Patent. Geron shall have the right to use
counsel of its own choice in any such action, and shall bring the action at its
own sole cost and expense. Any recovery from any such action shall (a) first be
applied to Geron’s costs and expenses, and (b) then to AngioChem’s costs and
expenses, and (c) any surplus shall then be treated as Net Sales, and shall be
subject to a royalty obligation of * percent (*%).
 
          6.2.3 Technology Patents.
 
               6.2.3.1 As between Geron and AngioChem, AngioChem shall have the
first right to assert the Technology Patents, at its own sole cost and expense,
using counsel of its choice, to abate infringement within the Field, and to
control the defense of any declaratory judgment action relating to the
Technology Patents. Within thirty (30) days after receipt of a written request
by Geron for AngioChem to assert the Technology Patents, AngioChem shall inform
Geron in writing if it elects to exercise its first right to assert the
Technology Patents hereunder. If AngioChem elects to exercise its first right,
AngioChem shall keep Geron informed of developments in any such action or
proceeding, including consultation on any settlement, the status of any
settlement negotiations and the terms of any offer related thereto. Geron shall
cooperate fully in such action, including, without limitation, being named as a
party plaintiff as necessary, and will provide any information or assistance
that AngioChem may reasonably request. In any such action, neither Geron nor
AngioChem shall knowingly take any position adverse to the issuance or
maintenance of any Product Patent. Any recovery from actions brought by
AngioChem hereunder shall (a) first be applied to AngioChem’s costs and expenses
in bringing the action, and (b) then to Geron’s costs and expenses in connection
with such action, and (c) any surplus shall then be shared equally by AngioChem
and Geron.
 
               6.2.3.2 If AngioChem notifies Geron in writing that it declines
to exercise its first right to assert the Technology Patents to abate
infringement within the Field, or fails to notify Geron of its intent to
exercise its first right within thirty (30) days after receipt of a written
request by Geron to do so, Geron shall be entitled to bring such action if the
alleged infringement involves the development or marketing of a product which is
being developed or marketed for the treatment of a cancer type for which Geron
is developing or marketing a Licensed Product, or which could reasonably be used
off-label for such cancer type. In any such action AngioChem shall cooperate
fully, including, without limitation, being named as a party plaintiff as
necessary, and will provide any information or assistance that Geron may
reasonably request. Geron shall have the right to use counsel of its own choice
in any such action, and shall bring the action at its own sole cost and expense.
Any recovery from actions brought by Geron hereunder shall (a) first be applied
to Geron’s costs and expenses in bringing the action, and (b) then to
AngioChem’s costs and expenses in connection with such action, and (c) any
surplus shall then be treated as Net Sales, and shall subject to a royalty
obligation of * percent (*%).

               6.2.3.3 Notwithstanding anything to the contrary in this Section
6.2.3, with respect to infringement of Technology Patents by a product which
would, under this Agreement, constitute a Licensed Product for use in the Field
then, where such product is a product proposed to be marketed by a Third Party
and in respect of which Geron or AngioChem has received a paragraph (iv)
certification under CFR 314.94(a)(12)(i)(A)(4) or its successor provisions, or
equivalents in any country, AngioChem’s right to initiate and prosecute an
appropriate legal action shall be a first right. Within five (5) days of receipt
of such certification, AngioChem shall provide Geron with a copy of such
certification and within ten (10) days of receipt of such certification shall
notify Geron if it elects not to exercise such first right and Geron shall
thereafter have the right to initiate and prosecute such action. In any such
action AngioChem shall cooperate fully, including, without limitation, being
named as a party plaintiff as necessary, and will provide any information or
assistance that Geron may reasonably request. Geron shall have the right to use
counsel of its own choice in any such action, and shall bring the action at its
own sole cost and expense. Any recovery from actions brought by Geron hereunder
shall (a) first be applied to Geron’s costs and expenses in bringing the action,
and (b) then to AngioChem’s costs and expenses in connection with such action,
and (c) any surplus shall then be treated as Net Sales, and shall subject to a
royalty obligation of * percent (*%).
 
          6.2.4 Additional Obligations. In any action to enforce the Licensed
Patents, the responsible Party shall keep the other Party informed of
developments in any such action or proceeding, including consultation on any
settlement, the status of any settlement negotiations and the terms of any offer
related thereto, and shall give good faith consideration to any suggestions of
the other Party. Neither Party shall enter into any settlement or compromise of
any action or proceeding involving the Licensed Patents that admits the
invalidity, unenforceability or non-infringement of any Licensed Patent or any
claim therein without the other Party’s approval, which approval shall not be
unreasonably delayed, withheld or conditioned.
 
     6.3 Patent Term Extension. Geron shall be entitled to apply for any and all
available extensions of patent term or supplemental patent certificates that may
be available to extend market exclusivity for Licensed Products, and AngioChem
shall promptly comply with and cooperate with any written request by Geron to
seek any of the foregoing with respect to the Technology Patents.
Notwithstanding the foregoing, commencing on the date of issuance of the first
Product Patent, if any, on a country-by-country basis within the Territory, and
for so long as such Product Patent remains in force, Geron shall have no right
to apply for, or to request that AngioChem apply for, any patent term extensions
or supplemental patent certificates with respect to the Technology Patents in
the country where such Product Patent is issued.
 
     6.4 Joint Intellectual Property.
 
          6.4.1 Notices. Each Party shall promptly provide written notice to the
other Party of any Joint Intellectual Property which such Party believes to be
patentable, together with the Party’s determination of inventorship for such
Joint Intellectual Property. In the event of a dispute as to inventorship, the
matter will be resolved in accordance with Section 11.6.

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

 

AngioChem and Geron shall jointly own all Joint Intellectual Property.
Notwithstanding anything to the contrary contained herein or under Applicable
Law, except to the extent set forth herein (including without limitation, the
grant of licenses by the Parties), the Parties agree that either Party may use
or license or sublicense to Affiliates or Third Parties all or any portion of
its interest in Joint Intellectual Property for any purpose without restriction
and without any obligation to provide any compensation or accounting to the
other Party, except that AngioChem may not conduct activities in the discovery,
development, manufacture, use, sale or importation of a Licensed Product for use
in the Field, without the prior written consent of Geron, and Geron may not
conduct activities in the discovery, development, manufacture, use, sale or
importation of products employing the Technology for use outside the Field,
without the prior written consent of AngioChem.
 
          6.4.2 Filing, Prosecution and Maintenance of Joint Intellectual
Property. The Parties shall determine which Party shall be responsible, at its
own expense, for filing, prosecution and maintenance of a Patent Right covering
Joint Intellectual Property on behalf of the Parties and in the Parties’ names,
based on whether such Patent Right is a Technology Patent (in which case it
shall be AngioChem) or a Product Patent (in which case it shall be Geron). If a
Party elects not to file or maintain a patent or patent application with respect
to any Joint Intellectual Property, such Party will inform the other Party in
writing, and the other Party will have the right, but not the obligation, to
apply for patent registration with respect to such Joint Intellectual Property,
in any country or countries, at its sole cost and expense, on behalf of the
Parties and in the Parties names.
 
          6.4.3 Interference, Opposition, Reexamination and Reissue Proceedings
Involving Joint Intellectual Property.
 
               6.4.3.1 Each Party shall, within ten (10) days of learning of any
interference, opposition, reissue or reexamination relating to Joint
Intellectual Property, inform the other Party of such proceeding.
 
               6.4.3.2 Neither Party shall initiate any interference,
opposition, reexamination, or reissue proceeding relating to a Patent Right
covering Joint Intellectual Property without the prior written consent of the
other Party, which consent shall not be unreasonably withheld. The Parties shall
determine which Party shall control any interference, opposition, reexamination,
or reissue proceeding relating to a Patent Right covering Joint Intellectual
Property, based on whether such Patent Right is a Technology Patent (in which
case it shall be AngioChem) or a Product Patent (in which case it shall be
Geron) and the expense of any interference, opposition, reexamination, or
reissue proceeding relating to Joint Intellectual Property shall be borne by the
Party controlling such interference, opposition, reexamination or reissue
proceeding. If a Party elects not to initiate or control any reexamination,
interference or reissue proceeding relating to any Patent Right covering Joint
Intellectual Property, such Party will inform the other Party in writing, and
the other Party will have the right, but not the obligation, to initiate or
control such proceedings with respect to such Joint Intellectual Property, in
any country or countries, at its sole cost and expense, on behalf of the Parties
and in the Parties’ names.
 
32
 

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

 

          6.4.4 Enforcement and Defense of Joint Intellectual Property. Each
Party shall give the other notice of either (i) any infringement,
misappropriation or misuse of Joint Intellectual Property or (ii) any
declaratory judgment action relating to Joint Intellectual Property that may
come to its attention. Geron shall have the sole right to assert the Joint
Intellectual Property, at its own sole cost and expense, using counsel of its
choice, to abate infringement within the Field. AngioChem shall have the sole
right to assert the Joint Intellectual Property, at its own sole cost and
expense, using counsel of its choice, to abate infringement involving use of the
Technology outside the Field. The parties shall mutually agree as to control of
enforcement actions relating to infringement of Joint Intellectual Property
other than infringement within the Field and infringement not involving the
Technology which shall be controlled by Geron, as set forth in the previous
sentence. In connection with any action under this Section 6.4.4, AngioChem and
Geron will cooperate fully, including being named as a party plaintiff as
necessary, and will provide each other with any information or assistance that
either may reasonably request. Each Party shall keep the other informed of
developments in any action or proceeding, including, to the extent permissible
by law, consultation on and approval of any settlement, the status of any
settlement negotiations and the terms of any offer related thereto. Each Party
shall consider in good faith any suggestions made by the other Party. Each Party
shall have the right to be represented by counsel of its own choice. Any
recovery obtained by either or both AngioChem and Geron in connection with or as
a result of any action contemplated by this Section 6.4.4, whether by settlement
or otherwise, shall be shared in order as follows:
 
          (A) the Party which initiated and prosecuted the action shall recoup
all of its costs and expenses incurred in connection with the action;
 
          (B) the other Party shall then, to the extent possible, recover its
costs and expenses incurred in connection with the action; and
 
          (C) (i) if the alleged infringement is within the Field the amount of
any recovery remaining shall then be treated as Net Sales, and shall be subject
to a royalty obligation of * percent (*%), or (ii) if the alleged infringement
is outside the Field, the amount of any recovery remaining shall then be
retained by AngioChem.
 
     6.5 Infringement Claims. If the exercise by either Party of the license
rights granted pursuant to Article 2 hereof results in any claim, suit or
proceeding lodged by a Third Party alleging intellectual property infringement
against a Party (or their respective Affiliates, subcontractors, consultants,
licensees or Sublicensees), such Party shall promptly notify the other Party
hereto in writing. The Party against whom suit is brought shall be the
controlling Party, provided that (a) if both Parties are sued, Geron shall be
the controlling Party; and (b) in no event shall the controlling Party enter
into any settlement or make any admission which admits or concedes that any
Licensed Product infringes any intellectual property of a Third Party or imposes
any financial or other obligation on the other Party without the prior written
consent of the other Party. The controlling Party shall keep the other Party
reasonably informed of all material developments in connection with any such
claim, suit or proceeding and the other Party may, at its sole cost and expense,
participate in the suit with counsel of its choice and shall cooperate fully
with reasonable requests made by the controlling Party with respect to such
claim, suit or proceeding.

     6.6 Diligence and Cooperation. In each case under this Article 6:
 
          6.6.1 the responsible Party shall use diligent efforts to obtain the
strongest available claims in any patent application it is prosecuting or in any
interference, opposition, reissue, or reexamination proceeding it is
controlling; provided that Geron shall not take any position in any prosecution
or interference, opposition, reissue, or reexamination proceeding that would be
adverse to the issuance or maintenance of any Technology Patent and AngioChem
shall not take any position in any prosecution or interference, opposition,
reissue, or reexamination proceeding that would be adverse to the issuance or
maintenance of any Product Patent;
 
          6.6.2 In connection with any interference, opposition, reissue, or
reexamination proceeding relating to Joint Intellectual Property, Geron and
AngioChem will cooperate fully and will provide each other with any information
or assistance that either may reasonably request. Each Party shall keep the
other Party informed of developments in any such action or proceeding,
including, to the extent permissible by law, consultation on and approval of any
settlement, the status of any settlement negotiations and the terms of any offer
related thereto.
 
          6.6.3 Each Party shall provide the other Party with written updates,
on a quarterly basis or at such other frequency as the Parties may agree in
writing, on the status of filing, prosecution and maintenance of the Technology
Patents or Product Patents or Patent Rights within Joint Intellectual Property,
as applicable, and the Parties shall make Commercially Reasonable Efforts to
meet twice per Calendar Year, or at such other frequency as the Parties may
agree in writing, to discuss intellectual property strategy with respect to the
Technology Patents or Product Patents or Patent Rights within Joint Intellectual
Property, as applicable;
 
          6.6.4 Each Party shall provide the other Party with an opportunity to
comment on proposed submissions to the United States Patent and Trademark Office
and patent offices worldwide with respect to Technology Patents and Product
Patents or Patent Rights within Joint Intellectual Property; provided that, if
such other Party has not provided comments within thirty (30) days after receipt
of such a proposed submission, the Party responsible for such proposed
submission may submit the submission without review by the other Party;
 
          6.6.5 At the request and expense of the Party seeking to obtain patent
protection with respect to Technology Patents or Product Patents or Patent
Rights within Joint Intellectual Property, the other Party shall assist in
securing patent rights in such Technology Patents or Product Patents or Patent
Rights within Joint Intellectual Property in any and all countries by executing
such applications, specifications, oaths, and all other instruments which the
prosecuting Party shall deem necessary in order to apply for and obtain such
rights, provided that Geron shall not be required take any position adverse to
the issuance or maintenance of any Product Patent and AngioChem shall not be
required take any position adverse to the issuance or maintenance of any
Technology Patent.

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

 

     6.7 Marking of Licensed Products. To the extent commercially feasible and
consistent with prevailing business practices and Applicable Law, Geron shall
mark, and shall cause its Affiliates and Sublicensees to mark, all Licensed
Products with the number of each issued patent that is a Licensed Patent Right
or a Joint Patent Right that applies to such Licensed Product.
 
7. CONFIDENTIALITY AND PUBLICATION
 
     7.1 Confidentiality.
 
          7.1.1 Nondisclosure Obligations. Except as expressly provided herein,
each of the Parties agrees that, for itself and its Affiliates, and for as long
as this Agreement is in effect and for a period of ten (10) years thereafter, a
Party and its Affiliates (the “Receiving Party”) receiving or possessing
Confidential Information of the other Party or its Affiliates (the “Disclosing
Party”) shall (i) not disclose such Confidential Information of the other Party
to any Third Party other than a Sublicensee without the prior written consent of
the Disclosing Party, except for disclosures expressly permitted below, and (ii)
not use such Confidential Information for any purpose except those licensed or
otherwise authorized or permitted by this Agreement.

Party can show by competent proof:
 
          (A) is publicly disclosed by the Disclosing Party, either before or
after it is disclosed to the Receiving Party hereunder;
 
          (B) was known to the Receiving Party, without any obligation to keep
it confidential or any restriction on its use, prior to disclosure by the
Disclosing Party;
 
          (C) is subsequently disclosed to the Receiving Party by a Third Party
lawfully in possession thereof and without any obligation to keep it
confidential or any restriction on its use;
 
          (D) is published by a Third Party other than a Sublicensee or
otherwise becomes publicly available or enters the public domain, either before
or after it is disclosed to the Receiving Party, in each case without breach of
an obligation of confidentiality under this Agreement by the Receiving Party; or
 
          (E) has been independently developed by employees or contractors of
the Receiving Party without the aid, application or use of Confidential
Information of the Disclosing Party, as evidenced by contemporaneous written
records.
 
Any combination of features or disclosures shall not be deemed to fall within
the foregoing exclusions merely because individual features are published or
available to the general public or in the rightful possession of the Receiving
Party, unless the combination itself and principle of operation are published or
available to the general public or in the rightful possession of the Receiving
Party.
 
35
 

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

 

          7.1.3 Authorized Disclosures. The Receiving Party may disclose
Confidential Information belonging to the Disclosing Party to the extent (and
only to the extent) such disclosure is reasonably necessary in the following
instances:
 
          (A) by either Party in order to comply with Applicable Law (including
any securities law or regulation or the rules of a securities exchange) and with
judicial process, if in the reasonable opinion of the Receiving Party’s counsel,
such disclosure is necessary for such compliance;
 
          (B) by either Party, in connection with prosecuting or defending
litigation, documentation required by a Regulatory Authority, and filing,

acquisition transaction;
 
provided that (1) with respect to any disclosure of Confidential Information
made pursuant to Sections 7.1.3(A) or 7.1.3(B), where reasonably possible, the
Receiving Party shall notify the Disclosing Party of the Receiving Party’s
intent to make any disclosure pursuant thereto sufficiently prior to making such
disclosure so as to allow the Disclosing Party adequate time to take whatever
action it may deem appropriate to protect the confidentiality of the information
to be disclosed, (2) with respect to any disclosure of Confidential Information
made pursuant to Section 7.1.3(C), any person or entity to whom any Confidential
Information is disclosed shall be bound prior to disclosure by confidentiality
and non-use restrictions at least as restrictive as those contained in this
Section 7.1, and (3) with respect to any disclosure of Confidential Information
made pursuant to Section 7.1.3(D), any person or entity to whom any Confidential
Information is disclosed must be bound prior to disclosure by commercially
reasonable obligations of confidentiality.
 
          7.1.4 Each Party agrees that it shall cooperate fully and in a timely
manner with the other Party with respect to all disclosures to the Securities
and Exchange Commission and any other Regulatory Authorities.
 
     7.2 Publication
 
          7.2.1 AngioChem acknowledges Geron’s interest in publishing the
results of the research, development and commercialization activities hereunder,
including, without limitation, the results of the Clinical Development Plan.
AngioChem shall not publish results, data or information arising from research,
development or commercialization activities conducted with respect to Licensed
Products under this Agreement, including, without limitation, results, data or
information arising from the Clinical Development Plan, without Geron’s prior
written consent, which consent shall be at Geron’s sole discretion. AngioChem
shall have the right to publish results, data or information arising from
research or development activities conducted by AngioChem prior to the Effective
Date, provided that (i) AngioChem shall deliver to Geron a copy of each proposed
publication, (ii) Geron shall have the right to review and comment on the
proposed publication within ten (10) days of receipt thereof, and (iii) Geron’s
comments shall be incorporated therein or the Parties shall otherwise cooperate
to ensure such that the proposed publication is mutually acceptable to the
Parties. Prior to making any publication containing Joint Intellectual Property,
unpublished Patent Rights or Know-How of the other Party, each Party shall
deliver to the other Party a copy of the proposed written publication or an
outline of an oral disclosure. The receiving Party shall have the right (a) to
propose modifications to the publication or presentation for patent reasons,
trade secret reasons or business reasons or (b) to request a reasonable delay in
publication or presentation in order to protect patentable information. If the
receiving Party requests a delay, the submitting Party shall delay submission or
presentation for a period of forty-five (45) days to enable patent applications
protecting each Party’s rights in Patent Rights or Know-How or Joint
Intellectual Property to be filed in accordance with Article 6 above. Upon
expiration of such forty-five (45) days, the submitting Party shall be free to
proceed with the publication or presentation. If the receiving Party requests
modifications to the publication or presentation, the submitting Party shall
edit such publication to prevent disclosure of trade secret information of the
receiving Party prior to submission of the publication or presentation.
Notwithstanding anything to the contrary in this Section 7.2.1, Geron may
publish its clinical or Manufacturing information relating to Licensed Products
with advance written notice to AngioChem.

Party, its Affiliates or their respective employees in any publicity, promotion,
news release or disclosure relating to this Agreement or its subject matter,
without the prior express written permission of the other Party, except as may
be required by Applicable Law. Each Party hereby consents to the use of its name
by the other Party in making reference to the existence of the Agreement only to
the extent permitted in this Section 7.3.2.
 
          7.3.3 Notwithstanding the above, either Party may disclose the terms

requirements of any nationally recognized securities exchange, quotation system
or over-the-counter market on which such Party has its securities listed or

LIKE DAMAGES OR LOSSES.
 
9. INDEMNIFICATION; INSURANCE
 
     9.1 Indemnification by AngioChem. Subject to the limitation of liability
set forth in Section 8.2 hereof, AngioChem hereby agrees at all times during the
term of this Agreement to indemnify, defend and hold harmless Geron and its
Affiliates, Sublicensees and each of their directors, officers, employees, and
agents (collectively, the “Geron Indemnified Parties”) from and against any and
liabilities, actions, losses, damages, claims or expenses, including reasonable
attorneys’ fees and costs (collectively, the “Indemnified Losses”) arising from
or based on a breach of AngioChem’s representations and warranties contained in
Section 8.1.1, provided that such indemnification obligation shall not apply to
Indemnified Losses on the part of a Geron Indemnified Party to the extent such
Geron Indemnified Party is adjudicated (in a final non-appealable judgment) to
have acted in a grossly negligent or willfully wrongful manner.
 
39
 

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

 

     9.2 Indemnification by Geron. Subject to the limitation of liability set
forth in Section 8.2 hereof, Geron hereby agrees at all times during the terms
of this Agreement to defend, indemnify and hold harmless AngioChem and its
Affiliates, and each of their directors, officers, employees, and agents
(collectively, the “AngioChem Indemnified Parties”) from and against any and all
Indemnified Losses (a) arising from or based on a breach of Geron’s
representations and warranties contained in Section 8.1.2, or (b) resulting from
personal injury, product liability or property damage relating to or arising
from: (i) the manufacture, use, promotion or sale of any Licensed Product by
Geron or an Affiliate or Sublicensee of Geron; or (ii) the use by any person of
a Licensed Product made, created, sold or otherwise transferred by Geron or an
Affiliate or Sublicensee of Geron,; provided that such indemnification
obligation shall not apply to Indemnified Losses on the part of an AngioChem
Indemnified Party to the extent such AngioChem Indemnified Party is adjudicated
(in a final non-appealable judgment) to have acted in a grossly negligent or
willfully wrongful manner.
 
     9.3 Notification of Claims; Conditions to Indemnification Obligations. The
Parties shall promptly notify each other in writing, or cause their respective
Indemnified Parties to give notice in writing to the prospective indemnifying
Party, of any Indemnified Losses with respect to which indemnification under

indemnifying Party’s obligations hereunder except to the extent it is actually
damaged by such failure. Provided that the indemnifying Party agrees in writing
to indemnify the other Party or its Indemnified Parties with respect to such
Indemnified Losses, the Party or its Indemnified Party requesting
indemnification shall permit the indemnifying Party to assume the defense of
such Indemnified Losses giving rise to the request, at the indemnifying Party’s
sole expense. The Party and its Indemnified Party requesting indemnification
shall cooperate with the indemnifying Party in such defense when reasonably
requested to do so. In no event shall the indemnifying Party compromise or
settle any Indemnified Loss in a manner that admits fault or negligence on the
part of the indemnified Party, or that would otherwise adversely affect any
rights of the indemnified Party, without the prior written consent of the
indemnified Party. The indemnifying Party shall have no liability under this
Article 9 with respect to Indemnified Losses settled or compromised without the
indemnifying Party’s prior knowledge and express written consent.
 
     9.4 Insurance. Each Party shall obtain and keep in force, at such Party’s

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

 

     10.2 Termination for Cause.
 
          10.2.1 Material Breach. Either Party may terminate this Agreement upon
written notice to the other Party for material breach but only after (1) the
non-breaching Party has provided the breaching Party with written notice and an
opportunity to cure as specified in 10.2.2 and the breaching Party has failed to
cure the breach; and (2) any dispute resolution invoked under Section 11.6
pertaining to the existence of a material breach has been resolved.
 
          10.2.2 Notice and Cure. In the event that a first Party believes that
the second Party is in material breach of its obligations hereunder as a result
of any cause or reason not attributable to any force majeure circumstance under
Section 11.1, then the first Party shall provide written notice to the second
Party providing a reasonably detailed explanation of the asserted material
breach. The second Party shall then either (1) cure such asserted material
breach within ninety (90) days after actual receipt of such written notice
(except in the case of a payment breach, in which event the cure period shall be
thirty (30) days or in the case of a breach of Section 4.5.2, in which event the
cure period shall be sixty (60) days (or such longer period as may be agreed by
the Parties)). or, (2) if the second Party believes in good faith that it is not
in material breach, initiate dispute resolution pursuant to Section 11.6,

          10.2.3 Financial Insolvency. Either Party may terminate this Agreement
upon written notice upon the filing or institution of bankruptcy,
reorganization, liquidation or receivership proceedings, or upon an assignment
of a substantial portion of the assets for the benefit of creditors by the other
Party; provided, however, that in the case of any involuntary bankruptcy or
other proceeding such right to terminate shall only become effective if the
Party consents to the involuntary bankruptcy or other proceeding or such
proceeding is not dismissed within ninety (90) days after the filing thereof.
 
          10.2.4 Arbitration in Lieu of Termination. Notwithstanding anything to
the contrary, if Geron believes that AngioChem has materially breached or
materially defaulted under this Agreement and has failed to cure such breach or
default as provided above, and Geron does not wish to terminate this Agreement,
then Geron shall be entitled to retain its license and seek arbitration pursuant
to Section 11.6 to determine whether AngioChem has materially breached or
defaulted under this Agreement and failed to timely cure such material breach or
default. If such arbitration determines that AngioChem has so materially
breached or defaulted and has failed to timely cure such material breach or
default, and that Geron has suffered losses arising out of or as a result of
such uncured material breach or default, then the arbitrators may award monetary
damages, objectively determined by such arbitrators to be a fair and reasonable
remedy for any losses determined to have been suffered by Geron by such material
breach or default by AngioChem, and the license rights granted by Geron to
AngioChem pursuant to Section 2.4 of this Agreement shall terminate.

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

 

     10.3 Termination by Geron. In addition to the right to terminate this
Agreement as set forth in Section 10.2 above, Geron shall have the right to
terminate this Agreement without cause in its sole discretion by giving one
hundred and eighty (180) days’ advance written notice to AngioChem. In the event
of any such termination, for such one hundred and eight (180) notice period and
for an additional ninety (90) days consecutively thereafter (a total of two
hundred and seventy (270) days), Geron shall remain responsible for conducting,
at its expense, any ongoing Geron human clinical trial(s) having patients
enrolled at the time Geron provides to AngioChem its written notice of
termination, unless a shorter period is agreed by the Parties. During such two
hundred and seventy (270) day period, Geron shall have the right to suspend or
terminate any such ongoing Geron human clinical trial in a manner compliant with
Applicable Laws, if, in Geron’s reasonable determination, such clinical trial
cannot or should not be completed. By way of example and without limitation,
such determination may be based on (i) safety or futility analysis concerns,
(ii) any request or requirement from a Regulatory Authority to suspend or
terminate such trial or any requirement of Applicable Law, (iii) stopping rules
for the trial, as defined in the study protocol, (iv) receipt of data or results
that Geron reasonably determines demonstrate that the Licensed Product will not
be safe or efficacious for the applicable indication, or (v) the inability to
enroll patients in the clinical trial despite Geron’s Commercially Reasonable
Efforts to do so. Within thirty (30) days after providing written notice to
AngioChem of any termination under this Section 10.3, Geron shall inform
AngioChem in writing of any Geron human clinical trial(s)s having patients
enrolled as of the date of Geron’s notice of termination, and shall inform
AngioChem in writing whether such clinical trial(s) will be continued by Geron
or terminated as permitted hereby. For the avoidance of doubt, if Geron notifies
AngioChem that it intends to continue any human clinical trial(s) being
conducted by it at the time of Geron’s notice of termination, all of the rights,
licenses, and sublicenses granted to Geron under this Agreement shall continue
as necessary to permit Geron to fulfill its ongoing obligations. Within one
hundred and eighty (180) days after receipt of Geron’s notice of termination
hereunder, AngioChem may elect to assume full responsibility, at AngioChem’s
expense, for any human clinical trial(s) being conducted by Geron at the time
Geron provides to AngioChem its written notice of termination, and in that case
the Parties shall cooperate in the orderly transition of such clinical trial(s)
to AngioChem prior to expiration of the two hundred and seventy (270) day period
of Geron’s obligation hereunder.
 
     10.4 Effect of Termination by AngioChem or Geron.
 
          10.4.1 Generally. Upon any termination of this Agreement by AngioChem
or Geron under Section 10.2.1 or 10.2.3, or by Geron under Section 10.3, (i) all
licenses granted by the breaching Party to the non-breaching Party (or to
AngioChem if Geron terminates this Agreement under Section 10.3) shall continue
in effect, and (ii) as of the effective date of such termination all relevant
licenses and sublicenses granted by the non-breaching Party to the breaching
Party (or to Geron if Geron terminates this Agreement under Section 10.3)
hereunder shall terminate automatically.
 
          10.4.2 Grant of License; Transfer of Data; Regulatory Filings and
Technology. Upon termination of this Agreement by AngioChem pursuant to Section
10.2.1 or 10.2.3, or upon termination by Geron pursuant to Section 10.3 at a
time when Geron is in material breach of this Agreement, and provided AngioChem
is not in material breach of this Agreement (provided further that any dispute
as to whether either Party is or is not in material breach of this Agreement
shall be subject to arbitration under Section 12.6), the licenses granted by
Geron in Section 2.4 shall survive, and Geron shall, upon request by AngioChem
and subject to (a) the terms and conditions of this Agreement, (b) sublicenses
granted to any Sublicensees whose sublicense survives termination in accordance
with Section 10.4.4, and (c) any other non-exclusive license or option rights
granted by Geron as of the effective date of termination, grant to AngioChem an
exclusive, worldwide license to develop and commercialize Licensed Products in
the Field, with a right to grant sublicense rights, under all Patent Rights that
claim a Licensed Product (or any component thereof) and Know-How Controlled by
Geron (including, without limitation, Geron’s interest in Joint Intellectual
Property) necessary or actually used by Geron at the time of termination for the
research, development and/or commercialization of Licensed Products (or any
component thereof) as single agents, in the Field. In addition, Geron shall
promptly transfer to AngioChem (subject to reasonably available resources and
for a reasonable period of time), for use within the scope of the foregoing
license right, and, where appropriate, assign in writing to AngioChem for use
within the scope of the foregoing license right, and cease its use, except as
unrelated to Licensed Products, of:
 
42
 

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

 

          (A) All data, reports and information relating to Licensed Products,
including, without limitation, data, reports and information relating to

          (C) All contracts with Third Parties (other than Sublicensees)
relating to Licensed Products (with the exception of any licenses or other
intellectual property contracts), including, without limitation, contracts with
manufacturers, contract research organizations, and consultants, to the extent
permissible under the terms of such agreements. If assignment of any such
contract requires the prior approval of the applicable Third Party, Geron will
promptly seek and use Commercially Reasonable Efforts to obtain, such approval;
 
          (D) All clinical and commercial supplies of Licensed Products in
Geron’s possession or control;
 
          (E) Documentation relating to the manufacturing process for Licensed
Products; and
 
          (F) Geron’s entire right, title and interest in and to any trademarks,
trade dress, logos, slogans, designs and copyrights, in each case relating
solely to such Licensed Products, including any registrations for the foregoing,
but excluding any of the foregoing that include Geron’s name or logo.
 
AngioChem shall thereafter be entitled to use the foregoing for the continued
development and commercialization of Licensed Products (on its own, or in
conjunction with a Third Party) within the scope of the foregoing license right.
 
43
 

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

 

          10.4.3 Royalty to Geron. In consideration of the grant of license and
transfer of data, regulatory filings and technology, by Geron to AngioChem in
accordance with Section 10.4.2, Geron shall be entitled to receive royalties in
the amount of * percent (*%) of Net Sales of Licensed Products by AngioChem, its
Affiliates and any sublicensees of AngioChem or its Affiliates greater than *
dollars (U.S.$*) in any Calendar Year, until such time as Geron has received an
amount (the “Payment Amount”) determined by the following formula: *
 
Within sixty (60) days following the Section 10.4.2 End Date, Geron will advise
AngioChem of Geron’s calculation of the Payment Amount, together with reasonable
supporting details. If AngioChem disputes such calculation, the matter will be
resolved pursuant to Section 11.6.
 
          10.4.4 Effect of Termination on Sublicenses.
 
               10.4.4.1 Obligations of Sublicensee. Notwithstanding anything to
the contrary set forth in this Agreement, no termination of this Agreement shall
be construed as a termination of any valid sublicense of any Sublicensee
hereunder, and thereafter each such Sublicensee shall be a direct licensee of
AngioChem, if, but only if, (x) any US Sublicensee is obligated to conduct (or
have conducted) and fund pre-clinical studies, clinical studies and regulatory
filings necessary to obtain Marketing Authorization for Licensed Products for
which such US Sublicensee has sublicense rights under the sublicense agreement
in the U.S., (y) any European Sublicensee is obligated to conduct (or have
conducted) and fund preclinical studies, clinical studies and regulatory filings

(i) such Sublicensee is in full compliance with all terms and conditions of its
sublicense at the time of termination of this Agreement;
 
(ii) such Sublicensee provides a written agreement to AngioChem to be bound to
AngioChem for all obligations, including the payment of milestones and
royalties, specified in the sublicense agreement; provided that if royalties or
milestones provided in the sublicense agreement are less than those payable by
Geron to AngioChem pursuant to this Agreement on account of the same events or
sales of Licensed Product by such Sublicensee, then such payment obligations of
Geron for such events or sales of Licensed Product shall apply;
 
(iii) such Sublicensee provides a written agreement to AngioChem stating that
such Sublicensee agrees that AngioChem shall not assume any obligation of Geron
to such Sublicensee pursuant to any representation, warranty, covenant,
commitment or indemnification provision;
 
(iv) such Sublicensee provides a written agreement stating that Sublicensee
agrees that in no event shall AngioChem be liable to the Sublicensee for any

by the Sublicensee of the sublicense agreement or (b) upon termination by the
Sublicensee of the sublicense agreement without cause and provided that
AngioChem is not in material breach of its obligations to the Sublicensee
hereunder, the Sublicensee shall, upon request by AngioChem and subject to the
terms and conditions of this Agreement:
 
     (A) grant to AngioChem, to the extent not in conflict with any other
obligation of the Sublicensee at the time of termination, an exclusive,
worldwide license, with a right to grant sublicense rights, under intellectual
property rights owned or controlled by such Sublicensee and necessary or
actually used, at the time of termination, by the Sublicensee for the research,
development and/or commercialization of Licensed Products (or any component
thereof) as single agents then being developed or marketed by such Sublicensee
under the sublicense agreement, such license to AngioChem to be for the limited
purpose of AngioChem’s research, development and/or commercialization of such
Licensed Products (or any component thereof);

11. MISCELLANEOUS
 
     11.1 Force Majeure. Neither Party shall be held liable to the other Party
nor be deemed to have defaulted under or breached this Agreement for failure or
delay in performing any obligation under this Agreement to the extent that such
failure or delay is caused by or results from causes beyond the reasonable
control of the affected Party, potentially including, but not limited to,
embargoes, war, acts of war (whether war be declared or not), insurrections,
riots, civil commotions, strikes, lockouts or other labor disturbances, fire,
floods, or other acts of God, or acts, omissions or delays in acting by any

and shall promptly undertake all reasonable efforts necessary to cure such force
majeure circumstances.
 
     11.2 Assignment/ Change of Control.
 
          11.2.1 Except as provided in this Section 11.2, this Agreement may not
be assigned or otherwise transferred, nor may any right or obligation hereunder
be assigned or transferred, by either Party without the consent of the other
Party, which consent shall not be unreasonably withheld, delayed or conditioned.
Notwithstanding the foregoing, either Party may, without the other Party’s
consent, assign this Agreement and its rights and obligations hereunder in whole
or in part to an Affiliate or in connection with a Change of Control (as defined
below), provided that the assigning Party shall promptly deliver written notice
of any such permitted assignment to the other Party, the assignee shall agree to
be bound to the obligations of the assigning Party and the assigning Party shall
remain liable for the performance of all obligations under this Agreement as if
the assignment did not occur, except in the case of a consolidation or merger
where the assigning Party is not the surviving entity, in which case the
assignee shall be solely liable. In addition, either Party may assign it rights
to receive any payments due hereunder to a Third Party who agrees in writing
that such payments are subject to all of the terms and conditions hereof. A
Party assigning its rights to receive payments due hereunder to a Third Party
shall promptly provide written notice of any such assignment of rights to the
other Party.
 
          11.2.2 For purposes of this Section 11.2, a “Change of Control” of a
Party shall be deemed to occur if such Party is involved in a merger,
reorganization or consolidation, or if there is a sale of all or substantially
all of such Party’s assets or business relating to this Agreement or if a person
or group other than the current controlling person or group shall effectively
acquire control of the management and policies of such Party.
 
          11.2.3 Any attempted assignment not in accordance with this Section
11.2 shall be void.
 
     11.3 Severability. If any one or more of the provisions contained in this
Agreement is held invalid, illegal or unenforceable in any respect, the
validity, legality and enforceability of the remaining provisions contained
herein shall not in any way be affected or impaired thereby, unless the absence
of the invalidated provision(s) adversely affects the substantive rights of the
Parties. The Parties shall in such an instance use their best efforts to replace
the invalid, illegal or unenforceable provision(s) with valid, legal and
enforceable provision(s) which, insofar as practical, implement the purposes of
this Agreement.
 
47

          11.6.1 The Parties shall negotiate in good faith and use reasonable
efforts to settle any dispute, controversy or claim arising from or related to
this Agreement or the breach thereof. If the Parties do not fully settle, and a
Party wishes to pursue the matter, each and every such dispute, controversy or
claim that is not an “Excluded Claim” shall be finally resolved by binding
arbitration to be held in New York, New York, in accordance with the Commercial
Arbitration Rules and Supplementary Procedures for Large Complex Disputes of the
American Arbitration Association (“AAA”) using the laws of the State of New
York, and judgment on the arbitration award may be entered in any court having

otherwise resolved. Either Party also may, without waiving any remedy under this
Agreement, seek from any court having jurisdiction any injunctive or provisional
relief necessary to protect the rights or property of that Party pending the
arbitration award. The arbitrators shall have no authority to award punitive or
any other type of damages not measured by a Party’s compensatory damages. Each
Party shall bear its own costs and expenses and attorneys’ fees and an equal
share of the arbitrators’ fees and any administrative fees of arbitration.
 
          11.6.4 Except to the extent necessary to confirm an award or as may be
required by law, neither a Party nor an arbitrator may disclose the existence,
content, or results of an arbitration without the prior written consent of both
Parties. In no event shall an arbitration be initiated after the date when

controversy or claim would be barred by the applicable New York statute of
limitations.
 
          11.6.5 The Parties agree that, in the event of a dispute over the
alleged breach of this Agreement, neither Party may terminate this Agreement
until final resolution of the dispute through arbitration or other judicial
determination. The Parties further agree that any payments made pursuant to this
Agreement pending resolution of the dispute shall be refunded if an arbitrator
or court determines that such payments are not due.
 
          11.6.6 As used in this Section, the term “Excluded Claim” shall mean a
dispute, controversy or claim that concerns (a) the validity or infringement of
a patent, trademark or copyright; or (b) any antitrust, anti-monopoly or
competition law or regulation, whether or not statutory.
 
     11.7 Entire Agreement; Amendments. This Agreement contains the entire
understanding of the Parties with respect to the subject matter hereof and the
licenses granted hereunder. Any other express or implied agreements and
understandings, either oral or written, with respect to the subject matter
hereof or the licenses granted hereunder are superseded by the terms of this
Agreement. This Agreement may be amended, or any term hereof modified, only by a
written instrument duly executed by authorized representatives of both Parties
hereto.
 
     11.8 Headings. The captions to the several Articles and Sections hereof are
not a part of this Agreement, but are merely for convenience to assist in
locating and reading the several Articles and Sections hereof.
 
     11.9 Independent Contractors. It is expressly agreed that Geron and
AngioChem shall be independent contractors and that the relationship between the
Parties shall not constitute a partnership, joint venture or agency. Neither
Geron nor AngioChem shall have the authority to make any statements,
representations or commitments of any kind, or to take any action, which shall
be binding on the other Party, without the prior written consent of the other
Party.
 
     11.10 Waiver. The waiver by either Party hereto of any right hereunder, or
of any failure of the other Party to perform, or of any breach by the other
Party, shall not be deemed a waiver of any other right hereunder or of any other
breach by or failure of such other Party, whether of a similar nature or
otherwise.
 
49
 

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

 

     11.11 Cumulative Remedies. Except as set forth in Section 3.9, no remedy
referred to in this Agreement is intended to be exclusive, but each shall be
cumulative and in addition to any other remedy referred to in this Agreement or
otherwise available under law.
 
     11.12 Waiver of Rule of Construction. Each Party has had the opportunity to
consult with counsel in connection with the review, drafting and negotiation of
this Agreement. Accordingly, the rule of construction that any ambiguity in this
Agreement shall be construed against the drafting Party shall not apply.
 
     11.13 Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

deliver such further instructions, and to do all such other acts, as may be
necessary or appropriate in order to carry out the purposes and intent of this
