Notice, Biogen Idec may elect, by delivery of written notice to Covella (the “Biogen Idec
Notice”), to enter into good-faith negotiations with Covella to obtain the Offered Rights.
Should Biogen Idec elect within such [***] ([***]) day period to enter into such negotiations with
Covella, both Biogen Idec and Covella shall promptly begin to negotiate in good faith to determine
whether they can agree on the terms of the definitive documents pursuant to which Biogen Idec would
be granted the Offered Rights.

               (c) In the event that Biogen Idec and Covella do not for any reason enter into
definitive documents with respect to the Offered Rights within [***] ([***]) calendar days after

itself or (ii) offer the Offered Rights to any Third Party upon terms not less favorable in the
aggregate to Covella than those specified in the last detailed written term sheet provided by
Biogen Idec to Covella, or if no such term sheet has been provided, on any terms. Covella may not
enter into an agreement for the Offered Rights on terms equal to or less favorable in the aggregate
to Covella than those specified in the last detailed written term sheet provided by Biogen Idec to
Covella without first re-offering the Offered Rights on such terms to Biogen Idec, and Biogen Idec
shall have [***] ([***]) calendar days to accept such re-Offered Rights. In the event that Biogen

               (d) For the avoidance of doubt, Covella may participate in discussions, without entering
into definitive documents, with a Third Party with respect to the Offered Rights throughout the
periods

               (b) Milestone Payment Calculations. Payments shall be due for each of the
four Clinical and Regulatory Milestones set forth in Section 5.2(a) as follows:

                         (i) In the first instance of any Existing Product or Other Product achieving a particular
Clinical and Regulatory Milestone for the first Indication, regardless of whether such Indication
is set forth on Exhibit 1.25, the corresponding payment specified in “Column A” (i.e.,
Milestone Payment for First Indication) of the table in Section 5.2(a) above shall be due with
respect to such milestone. Only one payment shall be due for such Clinical and Regulatory
Milestone under Column A of the table in Section 5.2(a) above under this Agreement.

                         (ii) In the first instance of any Existing Product or Other Product subsequently achieving
the same Clinical and Regulatory Milestone for a Second Indication that is set forth on Exhibit
1.25 (i.e., an Indication other than the Indication for which such Clinical and Regulatory
Milestone was already achieved as described in Section 5.2(b)(i) above and which is set forth in
Exhibit 1.25), the corresponding payment specified in “Column B” (i.e., Milestone Payment
for Second

Indication) of the table in Section 5.2(a) above shall be due with respect to such milestone.
Only one payment shall be due for such Clinical and Regulatory Milestone under Column B of the
table in Section 5.2(a) above under this Agreement.

                         (iii) In the first instance of any Existing Product or Other Product subsequently achieving
the same Clinical and Regulatory Milestone for a Third Indication that is set forth on Exhibit
1.25 (i.e., an Indication other than the Indications for which such Clinical and Regulatory
Milestone was already achieved as described in Section 5.2(b)(i) and (ii) above), the corresponding
payment specified in “Column C” (i.e., Milestone Payment for Third Indication) of the table in
Section 5.2(a) above shall be due with respect to such milestone. Only one payment shall be due
for such Clinical and Regulatory Milestone under Column C of the table in Section 5.2(a) above
under this Agreement.

                         (iv) Following one payment for each Clinical and Regulatory Milestone due under Columns A, B
and C of the table in Section 5.2(a) above under this Agreement, no additional milestone payments
shall be due under this Section 5.2 for any subsequent achievement of such Clinical and Regulatory
Milestone by any Product.

                         (v) Notwithstanding the foregoing, if clinical development of a particular Indication is
suspended after Covella has made the payment due under Section 5.2(a) above on the achievement of a
particular milestone for such Indication, there shall be no payment due under Section 5.2(a) upon
the accomplishment of the same milestone for a Second Indication provided that the development of
such Second Indication is continuing, and provided further that such Second Indication shall
thereafter be deemed the First Indication for any subsequent First Indication milestones not
achieved by the suspended Indication, and the next Indication to achieve any previously unachieved
Second Indication milestone shall trigger the Second Indication milestone payment under “Column B”
in the table in Section 5.2(a) above. Milestones for the Third Indication relative to the Second
Indication shall be payable in a similar manner as described herein. For the avoidance of doubt,
there shall be no retroactive adjustment of any previously paid milestone payments on account of
the replacement of one kind of Product by another kind of Product as the Product qualifying for a
First or Second Indication.

               (c) Cross-Credit for Milestone Payments and Sublicense Revenues.
Notwithstanding the provisions of Sections 5.2 and 5.6, if any milestone specified in Section 5.2
is also included as an event triggering the payment of Sublicense Revenues by a Sublicensee to
Covella under any sublicense (“Sublicensee Milestone Payment”), Covella shall only be
required to pay to Biogen Idec the amount of the applicable Clinical and Regulatory Milestone
payment under Section 5.2 plus the applicable percentage of the amount, if any, by which the
Sublicensee Milestone Payment exceeds the applicable Clinical and Regulatory Milestone payment, in
accordance with Section 5.6. Accordingly, any such payment made under Section 5.2 by Covella shall
be credited against (i.e., deducted from) the
base amount for purposes of calculating any Sublicense Revenues that would otherwise be due
to Biogen Idec under Section 5.6 for Sublicensee Milestone Payments.

               (d) Total Clinical and Regulatory Milestone Payments. In no event shall
the cumulative total amounts payable under Section 5.2(a) above exceed [***] Dollars ($[***]) in
the aggregate (i.e., [***] Dollars ($[***]) for the First Indication, assuming an Existing Product
is the first to achieve all applicable milestones, [***] Dollars ($[***]) for the Second
Indication, assuming an Existing Product is the first to achieve all applicable milestones, and
[***] Dollars ($[***]) for the Third Indication, assuming an Existing Product is the first to
achieve all applicable milestones).

               (e) [***]. Biogen Idec, [***], has the right to receive [***]. Biogen Idec
shall notify Covella of [***]. In connection with [***] hereunder, Biogen Idec shall, [***],
provide to Covella [***]. Notwithstanding anything to the contrary, Biogen Idec shall not have a
right [***]. The rights set forth in this Section 5.2(e) shall terminate on the closing date of an
acquisition by a Qualified Purchaser of all or substantially all of the business or assets of
Covella.

     5.3 Commercial Milestones. In addition, Covella shall pay Biogen Idec the one-time
commercial milestone payments set forth below following the end of the calendar year in which the
corresponding commercial milestone (each, a “Commercial Milestone”) for the first to occur
commercial milestone with respect to Existing Products or Other Products set out below.

     For the avoidance of doubt, the Commercial Milestones set forth in this Section 5.3 shall only
be paid upon the first occurrence of such cumulative Net Sales amounts to be achieved by all
Existing Products, taken cumulatively, and by all Other Products, taken cumulatively.

     5.4 Milestone Reports and Payments.

               (a) Covella shall notify Biogen Idec in writing within (i) [***] ([***]) calendar
days after the achievement of each milestone set out in Section 5.2 by Covella or its Affiliate or
(ii) the later of (A) [***] ([***]) calendar days after the achievement of each milestone set out
in Section 5.2 by a Sublicensee or (B) [***] ([***]) calendar days following receipt by Covella of
notice of such achievement from the Sublicensee or, if earlier, Covella’s becoming aware of such
achievement. Following receipt of such notice, Biogen Idec will notify Covella as to whether or
not it desires to receive equity in lieu of cash in accordance with Section 5.2(e). If Biogen Idec
elects to receive cash, Covella shall pay the appropriate amount to Biogen Idec within [***]
([***]) calendar days following
receipt of such notice from Biogen Idec. If Biogen Idec elects to receive equity, Covella
shall issue such equity to Biogen Idec within [***] ([***]) calendar days following receipt of such
notice from Biogen Idec.

               (b) Covella shall notify Biogen Idec in writing within [***] ([***]) calendar days after
the achievement of each milestone set out in Section 5.3, and each such notice shall be accompanied
by the appropriate milestone payment.

               (c) For the avoidance of doubt, the milestone payments set forth in Section 5.2
and 5.3 shall not be creditable against future royalties.

     5.5 Royalty Payments; Certain Adjustments.

               (a) Royalty Rate. Covella shall pay to Biogen Idec royalties on Net Sales
of each Product and Service at the rates set out below:

                         (i) Existing Products. The royalty rates for each Existing Product and Service based
on such Existing Product shall be as follows:

	 	 	 	 	 
	Annual Net Sales of Product	 	Royalty Rate
	Portion of Annual Net Sales of each Existing Product and
Services based on such Existing Product up to and including
[***] Dollars ($[***])
	 	 	[***]	%
	Portion of Annual Net Sales of each Existing Product and
Services based on such Existing Product in excess of [***]
Dollars ($[***]) and up to and including [***] Dollars
($[***])
	 	 	[***]	%
	Portion of Annual Net Sales of each Existing Product and
Services based on such Existing Product in excess of [***]
Dollars ($[***]) and up to and including [***] Dollars
($[***])
	 	 	[***]	%
	Portion of Annual Net Sales of each Existing Product and
Services based on such Existing Product in excess of [***]
Dollars ($[***])
	 	 	[***]	%

                         (ii) Other Products. The royalty rates for Other Products and Services based on such
Other Product shall apply on a Product-by-Product basis as follows: [***] percent ([***]%) of the
rates specified for Existing Products in Section 5.5(a)(i).

               (b) Certain Adjustments.

                         (i) Third Party Payments. If Covella, its Affiliate or Sublicensee is required to
pay royalties to a Third Party with respect to an Existing Product or Service based on such
Existing Product under any agreement to license or acquire intellectual property used in the
research, development, manufacture, use, sale or performance of such Existing Product or Service
based on such Existing Product, Covella may deduct [***] percent ([***]%) of the royalties payable
to each such Third Party from the amounts payable to Biogen Idec with respect to such Existing
Product or Service based on such Existing
Product pursuant to this Article V (and shall indicate
such deduction in the applicable royalty report pursuant to Section 7.1); provided that in no event
shall the royalties due to Biogen Idec pursuant to Section 5.5(a) with respect to such Existing
Product or Service based on such Existing

Product be so reduced by more than [***] percentage
points ([***]%). For the avoidance of doubt, no royalty offset shall be available for any Other
Product.

                         (ii) One Royalty. No more than one royalty payment shall be due under this Agreement
with respect to a sale of a particular Product or Service (e.g., even if such Product or Service is
covered by multiple Valid Claims). No royalty shall be payable under this Article V with respect
to sales of Products or Services among Covella and its Affiliates and its Sublicensees for resale,
nor shall a royalty be payable under this Article V with respect to any Products transferred for
use in, or performance of Services in, research and/or development, in clinical trials, in
compassionate use programs, as donations to non-profit institutions or government agencies, as
promotional free samples or any similar disposition at or below the manufacturing cost of the
Product for which no other consideration is provided by the recipient.

                         (iii) Combination Products. In the event that a Product is sold for a single price in
combination with another therapeutically active ingredient for which no royalty would be due
hereunder if sold separately, Net Sales from such combination product sales in a country for
purposes of calculating the amounts payable by Covella under this Section 5.5 shall be calculated
by multiplying the Net Sales of the combination product by [***]. In the event that separate sales
of such Product (without the additional therapeutically active ingredient) or such additional
therapeutically active ingredient were not made during the applicable royalty period, Net Sales
shall be calculated [***]. Any such estimates shall be determined using criteria approved by
Biogen Idec, such approval not to be unreasonably withheld, conditioned or delayed. Such estimates
shall be reported to Biogen Idec with the reports to be provided pursuant to Section 7.1 hereof.
If the Parties are unable to agree upon criteria to determine commercial value or the commercial
value, the Parties shall submit the matter to arbitration pursuant to Section 15.6, except that the
arbitrator shall use all reasonable efforts to complete any such arbitration within two (2) months
from the issuance of notice of a referral of such dispute and the Parties will cooperate in good
faith to permit such timing.

                         (iv) Generically Equivalent Products. With respect to each Existing Product, if there
are one or more generically equivalent products that compete with such Existing Product in a given
country (or in the European Union, which shall be treated as a single market for purposes of this
Section 5.5(b)(iv)) where there is no issued Valid Claim covering the sale of such Existing Product
in such country, and such generically equivalent product(s) have a combined market share of at
least [***] ([***]%) of the market (in units) for such Existing Product in such country (or
throughout the European Union, as the case may be), then (i) the applicable royalty for Net Sales
of such Existing Product in such country (or throughout the European Union, as the case may be)
shall be reduced to [***] percent ([***]%) of the royalties that would otherwise be due under this
Section 5.5, and (ii) no royalty reduction pursuant to Section 5.5(b)(i) shall apply, if otherwise
applicable.

               (c) Royalty Term. Covella’s obligation to pay royalties under this Section 5.5

which is the

later of: (i) expiration of the last Valid Claim in such country that would be
infringed by the sale of such Product or Service in such country; or (ii) [***] ([***]) years after
the First Commercial Sale of a Product (i.e., the first Product) or Service in such country.
Thereafter, no further royalties shall be due with respect to such Product or Service in such
country.

     5.6 Payments With Respect to Sublicense Revenue. In the event Covella or an Affiliate
of Covella sublicenses under Section 2.5, Covella shall pay Biogen Idec a portion of any Sublicense
Revenues resulting from sublicense agreements executed by Covella within the first [***] ([***])
years after the Effective Date, as set forth below:

               (a) If a sublicense agreement is executed in the first [***] ([***]) months after
the Effective Date, Covella shall pay Biogen Idec [***] percent ([***]%) of Sublicense Revenue
actually received by Covella under such sublicense agreement (including any extensions, amendments
and restatements thereof), regardless of when such Sublicense Revenue is accrued or received by
Covella;

               (b) if a sublicense agreement is executed in the second [***] ([***]) months after
the Effective Date, Covella shall pay Biogen Idec [***] percent ([***]%) of Sublicense Revenue
actually received by Covella under such sublicense agreement (including any extensions, amendments
and restatements thereof), regardless of when such Sublicense Revenue is accrued or received by
Covella; and

               (c) if a sublicense agreement is executed in the third [***] ([***]) months after
the Effective Date, Covella shall pay Biogen Idec [***] percent ([***]%) of Sublicense Revenue
actually received by Covella under such sublicense agreement (including any extensions, amendments
and restatements thereof), regardless of when such Sublicense Revenue is accrued or received by
Covella.

               (d) Covella shall have no obligation to share Sublicense Revenues with Biogen Idec
resulting from any sublicense agreement executed after [***] ([***]) months after the Effective
Date.

ARTICLE VI

PAYMENTS

     6.1 Royalty and Sublicense Revenue Payment Terms. Royalties and, if applicable,
Sublicense Revenue that have accrued during the period covered by each report provided pursuant to
Section 7.1 shall be due and payable on the date such report is due.

     6.2 Payment Method. Unless otherwise expressly stated in this Agreement, all
amounts specified in, and all payments to be made under, this Agreement shall be in United States
Dollars by wire transfer in immediately available funds to a U.S. account designated by the
receiving Party, or by other mutually

acceptable means. If any currency conversion shall be
required in connection with the payment of any royalties or other amounts under this Agreement,
such conversion shall be made by using the average of the interbank exchange rates for the purchase
and sale of United States Dollars reported by The Wall Street Journal (U.S., Western
Edition) on the last business day of the calendar quarter to which such royalty or other payments
relate.

     6.3 Exchange Control. If at any time legal restrictions prevent the prompt remittance
of part or all royalties or other amounts with respect to any country in the Territory where
Products or Services are sold, Covella shall have the right, at its option and upon written notice
to Biogen Idec, to make such payments by depositing, or causing to be deposited, the amount of such
payments in local currency to Biogen Idec’s account in a bank or other depository designated by
Biogen Idec in such country. When in any country in the Territory, legal restrictions prohibit both
the transmittal and the deposit of royalties on sales in such country, royalty payments shall be
suspended for as long as such legal restrictions are in effect and as soon as such legal
restrictions cease to be in effect, all royalties that Covella would have been under an obligation
to transmit or deposit but for the legal restrictions shall forthwith be deposited or transmitted,
to the extent allowable.

     6.4 Overdue Payments. In the event the initial license fee, any milestone payment,
royalty payment or payment of Sublicense Revenues payable by Covella to Biogen Idec under this
Agreement is not made when due, such outstanding payment shall accrue interest (from the date such
payment is due through and including the date upon which full payment is made) at a rate of [***]
percent ([***]%) per month from the due date until paid in full, provided that in no event shall
said annual rate exceed the maximum interest rate permitted by law in regard to such payments.
Such royalty payment when made shall be accompanied by all interest so accrued. Said interest and
the payment and acceptance thereof
shall not negate or waive the right of Biogen Idec to any other remedy, legal or equitable, to
which it may be entitled because of the delinquency of the payment.

     6.5 Tax Withholding. All payments hereunder shall be made free and clear of any
taxes, duties, levies, fees or charges, except for withholding taxes (to the extent applicable).
Covella shall make any applicable withholding payments due on behalf of Biogen Idec and shall
provide Biogen Idec upon request with such written documentation regarding any such payment as
available to Covella relating to an application by Biogen Idec for a foreign tax credit for such
payment with the United States Internal Revenue Service.

REPORTS,
RECORDS AND ACCOUNTING

Section 5.6 or the First Commercial Sale, whichever is earlier, Covella shall furnish to Biogen
Idec a written report for each calendar quarter during the remaining term of this Agreement
showing, on a country-by-country and Product-by-Product (or Service-by-Service) basis:

               (a) the gross sales of all Products and Services sold by Covella, its Affiliates
and Sublicensees during such calendar quarter and the calculation of Net Sales of the Products and
Services from such gross sales;

               (b) the applicable royalty rates and the royalties, payable in United States
Dollars, which shall have accrued under this Agreement based upon such Net Sales;

               (c) the amount of any Sublicense Revenue received by Covella during such calendar
quarter, if relevant;

               (d) the exchange rates used in determining the amount of royalties or Sublicense
Revenue, as applicable, payable in United States Dollars, as more specifically provided in Section
6.2; and

               (e) any reductions to or deductions from payments taken by Covella in accordance
with this Agreement.

     Reports to be provided by Covella to Biogen Idec under this Section 7.1 shall be due [***]
([***]) calendar days following the end of each calendar quarter (unless Covella has sublicensed
rights to commercialize Products or Services, in which event such reports shall be due within [***]
([***]) calendar days following the end of each calendar quarter). If for any quarter following
the first receipt
by Covella of Sublicense Revenue pursuant to Section 5.6 or the First Commercial Sale,
whichever is earlier, there were no Net Sales, and no Sublicense Revenues were received by Covella
in such quarter, a report stating such facts shall be due within [***] ([***]) calendar days

responsible designee) shall certify in writing that each such report is correct and complete.

     7.2 Records. Covella shall keep, and shall require that its Affiliates and

business of Covella, its Affiliate or Sublicensee, as the case may
be, for at least [***] ([***]) months following the end of the calendar year to which such books
and records pertain.

     7.3 Audits.

               (a) Audit Rights. Upon reasonable prior written notice from Biogen Idec
and not more than once in each calendar year nor more frequently than once with respect to records
covering any specific period of time, Covella shall permit, and shall require its Affiliates and
use Commercially Reasonable Efforts to require its Sublicensees, to permit, an independent
certified public accounting firm of nationally recognized standing selected by Biogen Idec and
reasonably acceptable to Covella to have access during normal business hours to such books of
account and records of Covella, and its Affiliates and Sublicensees, at such party’s principal
place of business, as may be reasonably necessary to verify the accuracy of the reports and
milestone payments provided by Covella pursuant to Section 7.1 for any calendar year ending not
more than [***] ([***]) months prior to the date of such request. If Covella is unable to obtain
from any Sublicensee such a right for Biogen Idec to audit the books of account and records of such
Sublicensee, Covella shall obtain for itself a reasonably comparable right for Covella to have an
independent certified public accounting firm of nationally recognized standing inspect and audit
such Sublicensee’s books and records, and (if Covella has not conducted such audit within the
preceding twelve (12) months and provided the results thereof to Biogen Idec in accordance with
Section 7.3(b)) shall exercise such audit rights on behalf and at the expense of Biogen Idec upon
Biogen Idec’ written request, using an independent certified public accounting firm of nationally
recognized standing selected by Covella and reasonably acceptable to Biogen Idec, and disclose the
results of any such audit to Biogen Idec in accordance with Section 7.3(b).

               (b) Audit Results. If as a result of such audit, it is established that
additional royalties, milestone payments and/or Sublicense Revenue were owed to Biogen Idec during
the period covered by such audit pursuant to Section 7.3(a), Covella shall promptly remit to Biogen
Idec the amount of such additional royalties, milestone payments and/or Sublicense Revenue,
together with interest on such amount which shall be calculated pursuant to Section 6.4. The fees
charged by such accounting firm in connection with any audit pursuant to this Section 7.3 shall be
paid by Biogen Idec; provided, however, that if a discrepancy in favor of Biogen Idec of more than
[***] percent ([***]%) of the payments due
hereunder for any calendar year within the period being audited is established, then Covella
shall pay the fees and expenses charged by such accounting firm in connection with such audit.

               (c) Materiality. For the avoidance of doubt, any material breach of this
Section 7.3 shall be deemed to be a material breach of this Agreement.

     7.4 Confidential Financial Information. Biogen Idec shall treat all financial
information subject to review under this Article VII as the Proprietary Information of Covella, and
shall cause its accounting firm to retain all such financial information in confidence, except to
the extent necessary for Biogen Idec to enforce its rights under this Agreement.

confidential information, data and materials supplied to such Party by the other Party (the
“Disclosing Party”) under this Agreement; provided that, unless the confidentiality of any
information, data or materials is expressly provided for in this Agreement, if any such

          (a) a Recipient may disclose Proprietary Information which it is otherwise
obligated under this Article X not to disclose, to its legal advisers who are subject to a duty of
confidentiality to the Recipient, to its Affiliates, and, in each case whether actual or potential,
to: Sublicensees or other collaboration partners, assignees, contractors (including manufacturers
and researchers), acquirers, investors, and medical, scientific, business and financial advisors,
on a need-to-know basis in accordance with such Recipient’s exercise of its rights or performance
of its obligations under this Agreement; provided that such persons agree to be bound by
obligations of confidentiality with respect to such Proprietary Information which are substantially
similar in scope and duration as those set forth in this Article X.

          (b) a Recipient may disclose Proprietary Information of the Disclosing Party to
government or other regulatory authorities to the extent that such disclosure is (i) required by
applicable law (including all applicable securities laws), regulation, agency or court order, or
(ii) is reasonably necessary in connection with the prosecution of any Patent, to obtain any
authorization to conduct clinical studies, or to obtain any Approval; provided that, in case of any
disclosures required as described in clause (i) above, the Recipient shall provide reasonable
advance notice to the Disclosing Party to allow such Party to oppose such disclosure or to request
confidential treatment of such Proprietary Information; provided, further, that Biogen Idec shall
only be permitted to disclose Proprietary Information of Covella under clause (ii) above with
respect to Biogen Idec Patents exclusively licensed hereunder and for no other purpose.

     10.3 Manufacturing Know-How. In addition to the obligations of confidentiality
applicable to the Confidential Information of Biogen Idec pursuant to this Article X, until such
time as Biogen Idec ceases to maintain the Manufacturing Know-How as a trade secret, Covella (a)
shall maintain in confidence all Manufacturing Know-How, and (b) shall not use such Manufacturing
Know-How for any purpose except in manufacturing or having manufactured Products or Services under
the license granted
under Section 2.2 of this Agreement or pursuant to the sublicense rights of Section 2.4 of
this Agreement.

     10.4 Prior Agreement. This Agreement supersedes the Mutual Confidentiality Agreement
between Covella and Biogen Idec, Inc., a Delaware corporation and a Controlled Affiliate of Biogen
Idec, dated February 1, 2008 (the “Mutual Confidentiality Agreement”). All information
exchanged between the Parties under the Mutual Confidentiality Agreement shall be deemed to have
been disclosed under this Agreement on a going-forward basis and shall be subject to the terms of
this Article X as of the Effective Date.

     10.5 Terms of Agreement. The terms of this Agreement shall not be disclosed by either
Party without the prior written consent of the other Party, which shall not be unreasonably
withheld; provided,

			
	 	 	 
		 	01-09-2009

-31-

 

however that either Party may make such a disclosure (a) to the extent
required by law or by the requirements of any nationally recognized securities exchange, quotation
system or over-the-counter market on which such Party has its securities listed or traded, or (b)
to any Affiliates, legal advisors, accountants, and, in each case whether actual or potential, to:
contractors (including contract manufacturers and researchers); licensees, sublicensees or other
collaboration partners; acquirers, investors; lenders and other potential financing sources, who
are obligated to keep such information confidential. In the event that such disclosure is required
as described in clause (a) of the preceding sentence, the disclosing Party shall make reasonable
efforts to provide the other Party with notice beforehand and to coordinate with the other Party
with respect to the wording, timing and any redactions of any such disclosure.

     10.6 Press Release. Covella, upon or after the Effective Date, shall have the right to
issue a press release with respect to this transaction, subject to Biogen Idec’s prior written
consent, which shall not be unreasonably withheld, conditioned or delayed. Such press release
shall not include any financial terms of this transaction. Once such press release or any other
written statement is approved for disclosure by Biogen Idec, Covella may make subsequent public
disclosure of the contents of such statement without the further approval of Biogen Idec.
Notwithstanding the foregoing, as of the Effective Date, both Parties shall have the right to
disclose to Third Parties, without the need for a confidentiality agreement, the following
information: (i) Biogen Idec has exclusively licensed the rights to its Anti-VLA1 Antibody Program
to Covella, and/or (ii) Biogen Idec is a stockholder of Covella.

ARTICLE XI

INTELLECTUAL
PROPERTY AND INFRINGEMENT

     11.1 Ownership of Inventions.

          (a) Modified Cell Lines and Antibodies.

                    (i) In the event that Covella (or its Affiliate or Sublicensee) modifies any cell line
received from Biogen Idec as Biogen Idec Know-How or Manufacturing Know-How under this Agreement,
Biogen Idec shall solely own all intellectual property rights in and to such modified cell lines
and antibodies produced by such modified cell lines (other than antibodies derived from the Biogen
Idec Know-How and owned by Covella as set forth in Section 11.1(a)(ii)), and all derivatives of
such materials, whether such materials result from the activities of Covella, its Affiliates or any
Sublicensee (“Modified Know-How”). Covella, on behalf of itself and its Affiliates, hereby
makes all assignments, and agrees to execute all documents, necessary to perfect Biogen Idec’s
ownership of such intellectual property rights as set forth in the preceding sentence, and shall
require its Sublicensees to make all such necessary assignments and execute all such necessary
documents; provided, however, that (i) Covella and its Affiliates and Sublicensees shall retain an
exclusive license under such intellectual property rights

			
	 	 	 
		 	01-09-2009

-32-

 

to use (and authorize others to use)
Modified Know-How (which shall be deemed to be Biogen Idec Know-How or Manufacturing Know-How
according to the categorization of the original cell line) in the exercise of licenses or rights
conveyed under this Agreement without additional payment to Biogen Idec.

                    (ii) As between the Parties, Covella (or its Affiliates or Sublicensees) shall solely own all
intellectual property rights, other than pre-existing Patents or other intellectual property rights
of Biogen Idec or its licensors, in any inventions or improvements made by Covella (or its
Affiliates or Sublicensees) after the Effective Date relating to or comprising (A) anti-VLA1
integrin antibodies produced by cell lines within the Biogen Idec Know-How, and all derivatives of
such materials (including anti-VLA1 integrin antibodies and fragments thereof produced by modified
versions of such cell lines and derivatives thereof), and (B) genetic materials encoding the
foregoing.

          (b) General. Except as expressly set out in Section 11.1(a), as between
the Parties, title to all inventions and other intellectual property made solely by personnel of
Covella in connection with this Agreement shall be owned by Covella, and title to all inventions
and other intellectual property made solely by personnel of Biogen Idec in connection with this
Agreement shall be owned by Biogen Idec.

     11.2 Patent Prosecution and Maintenance.

          (a) By Covella. Covella shall have the right, at its expense, to control the
preparation, filing, prosecution and maintenance solely of the Prosecution Patents. As used in
this Section 11.2, “prosecution” shall include interferences, re-examinations, reissues,
oppositions, obtaining certificates of correction, patent term extensions, Supplementary Protection
Certificates, and the like. Covella shall consult with Biogen Idec in good faith regarding the
preparation, filing, prosecution and maintenance of the Prosecution Patents. Covella shall provide
Biogen Idec with semiannual updates on the status of prosecution of the Prosecution Patents in
every jurisdiction and shall, in any event, provide notice to Biogen Idec of any action that may be
taken with respect to a Prosecution Patent (i) with the U.S. Patent and Trademark Office at least
[***] calendar days prior to the deadline for such action, and (ii)
with or any foreign patent office at least [***] calendar days prior to the deadline for such
action, or if shorter, the maximum period allowed by such foreign patent office. Covella shall have
the right to apply for an extension of the term of any Patent within the Prosecution Patents if
available under the Drug Price Competition and Patent Term Restoration Act of 1984 and/or European,
Japanese and other foreign equivalents of this law, including any foreign laws extending marketing
exclusivity for a Product or Service, such as a Supplementary Protection Certificate. Covella
shall, at a minimum, to the extent supported by the disclosure of each Prosecution Patent,
diligently prosecute claims within the Prosecution Patents covering the monoclonal antibody hAQC2
composition of matter and claims within the Prosecution Patents covering the use of anti-VLA-1
antibodies in the treatment of the following indications: [***] (the “Core Claims”) within
the jurisdictions set forth in Exhibit 10.2A (the “Required Countries”).

Exchange Commission. Confidential treatment has been requested with respect to the omitted
portions.

-33-

 

          (b) By Biogen Idec. If Covella determines not to prosecute any claim or
Patent within the Biogen Idec Patents (other than prosecution of the Core Claims in the Required
Countries, for which, for the avoidance of doubt, Covella has the obligation of prosecution), then
Covella shall provide Biogen Idec with written notice of such decision at least [***] ([***])
calendar days prior to the deadline for filing any such prosecution action for any claim or Patent
or the date on which the abandonment of any such claim or Patent would become effective. In such
event, Biogen Idec shall have the right, but not the obligation, at its option and expense, to
control the preparation, filing, prosecution and maintenance of such claim or Patent. If Covella
or any of its Affiliates or Sublicensees subsequently uses, makes, offers for sale, sells or
imports a Product in any jurisdiction in which Biogen Idec has assumed patent prosecution under
this Section 11.2(b), Covella shall, at the time of First Commercial Sale in such jurisdiction,
reimburse Biogen Idec for the out-of-pocket costs of such patent prosecution actually incurred,
which costs shall not be offset against any other amounts due under this Agreement. For the
avoidance of doubt, Biogen Idec shall, at all times, have exclusive control over the prosecution of
the Reserved Prosecution Patents, including enforcement rights, at its own expense.

          (c) Cooperation. Each Party shall cooperate with the other Party in
connection with activities relating to the preparation, filing, prosecution and maintenance of the
Biogen Idec Patents undertaken by the other Party pursuant to this Section 11.2, including: (i)
making available to such other Party in a timely manner any documents or information reasonably
necessary or appropriate to facilitate such other Party’s preparation, filing, prosecution and
maintenance of any Biogen Idec Patent; and (ii) if and as appropriate, signing (or causing to have
signed) all documents relating to the preparation, filing, prosecution and maintenance of any
Biogen Idec Patent by such other Party. Each Party shall also promptly provide to the other Party
all information reasonably requested by such other Party with regard to such Party’s activities
pursuant to this Section 11.2.

     11.3 Enforcement.

          (a) Notice. In the event either Party learns of any infringement of the
Biogen Idec
Patents by the manufacture, use, sale, offer for sale or importation of any product or service
in the Field (an “Infringement”), it shall promptly provide written notice to the other
Party of such Infringement and shall supply such other Party with all evidence it possesses
pertaining to such Infringement.

          (b) Infringement Action. Covella (directly or through its nominee) shall have the
first right, but not the obligation, to seek to abate any Infringement of a Prosecution Patent, or
to file suit against an infringing party. In the event that Covella or its nominee does not,
within [***] ([***]) calendar days from date of a request by Biogen Idec to do so, take action to
abate such Infringement, Biogen Idec shall have the right, but not the obligation, to enforce the
Biogen Idec Patents in connection with such Infringement in its own name, and at its own cost and
expense. For the avoidance of doubt, Biogen Idec has the exclusive right to seek to abate any
Infringement of Reserved Prosecution Patents.

Exchange Commission. Confidential treatment has been requested with respect to the omitted

		 	01-09-2009

-34-

 

          (c) Cooperation. In any suit, action or other proceeding in connection
with an Infringement (an “Infringement Action”), the Party assuming the primary role in the
Infringement Action (“Controlling Party”) shall keep the non-Controlling Party reasonably
informed of the progress of such Infringement Action. The non-Controlling Party shall cooperate
fully with the Controlling Party, including by joining as a nominal party and executing such
documents as the Controlling Party may reasonably request, provided that Biogen Idec shall not be
required to transfer any right, title or interest in or to any of the Biogen Idec Patents to
Covella or any Third Party to confer standing to bring an Infringement Action. In any case, the
non-Controlling Party shall have the right, even if not required to be joined, to participate in
any Infringement Action with counsel of its own choice at its own expense.

          (d) Costs and Recoveries. The Controlling Party with respect to any
Infringement Action may not settle any such action, or otherwise consent to any adverse judgment in
any such action, that restricts the scope of, or admits the unenforceability or invalidity of, any
Biogen Idec Patent without the express written consent of the non-Controlling Party, which consent
shall not be unreasonably withheld. Any damages, monetary awards or other amounts recovered,
whether by judgment or settlement, pursuant to any suit, proceeding or other legal action taken
under this Section 11.3 shall applied as follows:

               (i) First, to reimburse the Parties for their respective costs and expenses (including
reasonable attorneys’ fees and costs) incurred in prosecuting such Infringement Action;

               (ii) Second, if and to the extent lost sales are specifically determined by the adjudicating
authority, to Covella in reimbursement for lost sales (net of royalties) associated with Products
or Services and to Biogen Idec in reimbursement for lost royalties owing hereunder based on such
lost sales;

               (iii) Third, any amounts remaining shall be allocated [***] percent ([***]%) to the
Controlling Party and [***] percent ([***]%) to the non-Controlling Party.

     For the avoidance of doubt, if any settlement results in the granting to the alleged infringer
of a sublicense of any of the Biogen Idec Technology with running royalties payable on
post-settlement sales by the alleged infringer, such alleged infringer shall be deemed to be a
Sublicensee and such royalties on post-settlement sales (x) shall be subject to all applicable
royalty obligations hereunder, and (y) shall not be subject to this Section 11.3(d); provided, that
any upfront or milestone payments or the like shall be deemed monetary awards and subject to this
Section 11.3(d).

     11.4 Defense of Infringement Claims. If any Product manufactured, used or sold, or
any Service performed, by Covella, its Affiliates, or Sublicensees, becomes the subject of a Third
Party’s claim or assertion of infringement of a Patent relating to the manufacture, use, sale,
offer for sale or importation of such Product or Service, the Party first having notice of the
claim or assertion shall

Exchange Commission. Confidential treatment has been requested with respect to the omitted
portions.

 promptly
notify the other Party, and the Parties shall promptly confer to
consider the claim or assertion and the appropriate course of action. Any such claim naming Biogen
Idec as a defendant shall be subject to Section 14.1. In any event, each Party shall reasonably
assist the other Party and cooperate in connection with any litigation in which such Party is not
named as a defendant, at the defending Party’s request and expense.

     11.5 Labeling and Promotional Materials. Subject to applicable laws and regulations,
labeling on all Products and Services sold by or on behalf of Covella, its Affiliates, or
Sublicensees pursuant to this Agreement and on all package inserts will identify Biogen Idec as
licensor of the Biogen Idec Patents and will comply with all patent marking requirements as
specified in 35 USC § 287.

ARTICLE XII

TERM
AND TERMINATION

     12.1 Term. This Agreement shall commence on the Effective Date and, unless terminated
earlier pursuant to Sections 8.1, 12.2, 12.3 or 12.4 shall continue in full force and effect on a
country-by-country basis until no further royalties would be due in such country (the
“Term”). Upon expiration (but not early termination of this Agreement) in a given country
in accordance with this Section 12.1, the licenses and rights granted by Biogen Idec under this
Agreement will continue on a fully paid-up, royalty-free basis in such country.

     12.2 Termination for Material Breach. If either Party materially breaches this
Agreement at any time, the non-breaching Party shall have the right to terminate this Agreement by
written notice to the breaching Party, if such material breach is not cured within ninety (90)
calendar days after written
notice is given by the non-breaching Party to the breaching Party specifying the material
breach. If the material breach set forth in such written notice is not reasonably capable of cure
within ninety (90) calendar days, the breaching Party shall be entitled to an additional ninety
(90) calendar days to attempt to cure such material breach, provided that within the initial ninety
(90) day period the breaching Party has submitted a cure plan that is reasonably acceptable to the
non-breaching Party.

     12.3 Termination for Financial Insecurity. In the event that either Party files for
protection under bankruptcy laws, makes an assignment for the benefit of creditors, appoints or
suffers appointment of a receiver or trustee over its property, files a petition under any
bankruptcy or insolvency act or has any such petition filed against it which is not discharged
within ninety (90) calendar days of the filing thereof, then the other Party may terminate this
Agreement effective immediately upon written notice to such Party.

     12.4 Termination by Covella or Biogen Idec.

			
	 	 	 
		 	01-09-2009

-36-

 

          (a) This Agreement may be terminated by Covella, in its sole discretion, upon
sixty (60) calendar days written notice to Biogen Idec.

          (b) This Agreement may be terminated by Biogen Idec, in its sole discretion, upon
written notice to Covella at any time after the date (the “End Date”) which is thirty (30)
calendar days following Biogen Idec’s delivery of the initial stability testing of the Existing
Inventory pursuant to the Services and Supply Agreement establishing that the drug substance within
the Existing Inventory qualifies as Compliant Material, if and only if Biogen Idec has not
received, on or prior to the End Date, the equity consideration under the terms required by and in
full satisfaction of Section 5.1 of this Agreement. This Agreement may be terminated by Biogen
Idec pursuant to Section 8.1 herein, if such provision is applicable.

     12.5 Effect of Expiration or Termination.

          (a) Upon termination of this Agreement in accordance with Sections 8.1, 12.2, 12.3
or 12.4:

                    (i) The licenses and rights granted by Biogen Idec to Covella under Article II will
immediately terminate; provided that, any sublicenses granted in accordance with Section 2.5 prior
to the date of the corresponding notice of breach (in the case of Section 12.2) or termination (in
the case of Section 8.1, 12.3 or 12.4) shall survive if the relevant Sublicensee agrees in writing
to be bound by the terms of this Agreement as such terms apply to such Sublicensee (in which event,
such Sublicensee will be deemed a direct licensee of Biogen Idec); provided, further, that any such
Sublicensee shall only be responsible for any payments that become due as a result solely of such
Sublicensee’s activities after the effective date of any such termination. For clarity,
Sublicensees who agree to be bound by the terms of
this Agreement pursuant to this Section 12.5(a)(i) will not be responsible for: (A) any
payments due to Biogen Idec under Section 5.6 and that Section shall be terminated upon the
termination of this Agreement between Covella and Biogen Idec; nor (B) any milestone payments
already paid by Covella prior to the effective date of any such termination, nor any milestone
payments that may accrue as a result of the activities of any other Sublicensee after the effective
date of any such termination of this Agreement; but for purposes of determining the amount of
milestone payments under Section 5.2 and/or Section 5.3, any milestone that was met and for which
payment has been made by or on behalf of Covella prior to such termination shall be deemed to have
been paid by the Sublicensee.

                    (ii) Covella shall return to Biogen Idec all written Biogen Idec Know-How and Manufacturing
Know-How, and all copies and any other tangible and electronic embodiments thereof in Covella’s
possession, subject to the rights of any surviving Sublicensee.

     12.6 Survival of Certain Obligations. The expiration or termination of this
Agreement for any reason shall not relieve either Party of any obligation accruing on or prior to
such expiration or termination, or which is attributable to a period prior to such expiration or
termination, nor preclude

			
	 	 	 
		 	01-09-2009

-37-

 

either Party from pursuing any rights and remedies it may have under this
Agreement, or at law or in equity, which accrued or are based upon any event occurring prior to
such expiration or termination. The following provisions shall survive the expiration or
termination of this Agreement for any reason: Article I (Definitions); Article VI (Payments);
Article X (Confidentiality); Article XIV (Indemnification and Insurance); Article XV
(Miscellaneous); Section 5.1 (Equity Grant); Section 7.2 (Records); Section 7.3 (Audits); Section
11.1 (Ownership of Inventions); Section 12.5 (Effect of Termination); Section 13.4 (Disclaimer);
and this Section 12.6 (Survival of Certain Obligations).

     12.7 Rights in Bankruptcy. All rights and licenses granted under or pursuant
to this Agreement by either Party are, and will otherwise be deemed to be, for purposes of Section
365(n) of Title 11 of the United States Code (the “U.S. Bankruptcy Code”), licenses of
rights to “intellectual property” as defined under Section 101 of the U.S. Bankruptcy Code.

covenant or agreement made or undertaken by Covella under this Agreement.

     14.3 Indemnification Procedures. In the event that any Indemnitee (either a Covella
Indemnitee or a Biogen Idec Indemnitee) intends to claim indemnification under this Article XIV,
such Indemnitee shall promptly notify the other Party in writing of the alleged Liability. The
indemnifying Party (“Indemnifying Party”) shall have the right to control the defense
thereof, provided that counsel for the Indemnifying Party, who shall conduct the defense of such
claim or any litigation resulting therefrom, shall be approved by the Indemnitee (which approval
shall not be unreasonably withheld), and the Indemnitee may participate in such defense at such
Indemnitee’s expense (unless the Indemnitee shall have reasonably concluded, based upon a written
opinion from outside legal counsel, that there may be a conflict of interest between the
Indemnifying Party and the Indemnitee in the defense of such action, in each of which cases the
Indemnifying Party shall pay the fees and expenses of one law firm serving as
counsel for the Indemnitee). The failure of any Indemnitee to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under this Agreement to the extent that
such failure to give notice did not result in prejudice to the Indemnifying Party or the
Indemnifying Party’s insurer. The Indemnifying Party, in the defense of any such claim or
litigation, shall not, except with the approval of the Indemnitee (which approval shall not be
unreasonably withheld), consent to entry of any judgment or enter into any settlement which (i)
would result in injunctive or other relief being imposed against the Indemnitee; or (ii) does not
include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnitee
of a release from all liability in respect to such claim or litigation. The Indemnitee shall
furnish such information regarding itself or the claim in question as the Indemnifying Party may
reasonably request in writing, and shall be reasonably required in connection with the defense of
such claim or litigation resulting therefrom.

     14.4 Insurance. Covella shall, at its sole expense, obtain and maintain the following
insurance on its own behalf, with insurance companies having an A. M. Best Rating of “A-, VII” or
better:

          (a) From the initiation of the first clinical trial for a Product until the date [***]
([***]) years after the last dosing of a human subject under the last clinical trial for a Product,
Covella shall maintain coverage for each such clinical trial in an amount not less than (i) [***]
Dollars ($[***]) per

occurrence and [***] Dollars ($[***]) annual aggregate for any Phase I
clinical trial, and (ii) [***] Dollars ($[***]) per occurrence and [***] Dollars ($[***]) annual
aggregate for any Phase II or Phase III clinical trial;

          (b) During the Term, Covella shall maintain comprehensive or commercial general
liability insurance (contractual liability included) with limits of at least: (i) each occurrence,
[***] Dollars ($[***]); (ii) personal and advertising injury, [***] Dollars ($[***]); and (iii)
general aggregate (commercial form only), [***] Dollars ($[***]).

          (c) Such insurance shall name Biogen Idec MA Inc. as an additional insured. Covella
shall furnish Biogen Idec with certificates of insurance showing compliance with all requirements
set forth in this Section 14.4. Such certificates shall: (i) indicate that Biogen Idec has been
endorsed as an additional insured under the coverage referred to above; and (ii) include a
provision that the coverage shall be primary and shall not participate with nor shall be excess
over any valid and collectable insurance or program of self-insurance carried or maintained by
Biogen Idec. Covella shall notify Biogen Idec within thirty (30) calendar days of any change in
the terms of such insurance from those set forth in the most recent certificate of insurance
provided to Biogen Idec pursuant to this Section 14.4. The coverage and limits referred to above
shall not in any way limit the liability of Covella hereunder. Covella shall require Sublicensees
and Affiliates, if performing clinical trials or offering for sale or selling any Product, to carry
equivalent insurance and to comply with all provisions of this Section 14.4 (mutatis mutandis).

     15.1 Force Majeure. Neither Party shall be held liable or responsible to the other
Party, nor be deemed to have defaulted under or breached this Agreement, for failure or delay in

including fire, floods, embargoes, power shortage or failure, acts of war (whether war be declared
or not), insurrections, riots, terrorism, civil commotions, strikes, lockouts or other labor
disturbances, acts of God or any acts, omissions or delays in acting by any governmental authority

their economic effect, sufficiently similar to the invalid provisions that it can be reasonably
assumed that the Parties would have entered into this Agreement with such provisions. In the event
that such provisions cannot be agreed upon, the invalidity, illegality or unenforceability of one
(1) or more provisions of the Agreement shall not affect the validity of this Agreement as a whole.

     15.4 Notices. Any notice, consent or report required or permitted to be given or made
under this Agreement by one Party to the other Party shall be in English and in writing, delivered

Convention on Contracts for the International Sales of Goods.

     15.6 Arbitration. 

          (a) Except as otherwise expressly provided in this Section 15.6, the Parties agree
that any dispute, claim or controversy arising under, out of, or in connection with this Agreement
(a “Dispute”) as to the breach, performance or interpretation of this Agreement, such
Dispute shall, upon written notice of either Party to the other, be referred for resolution by
final, binding arbitration in accordance with the provisions of this Section 15.6. The arbitration

the English language, by a single arbitrator. The arbitrator shall engage an independent
expert with experience in the subject matter of the Dispute to advise the arbitrator.

          (b) With respect to any Dispute referred to arbitration pursuant to Section
15.6(a), the Parties and the arbitrator shall use all reasonable efforts to complete any such
arbitration within six (6) months from the issuance of notice of a referral of any such Dispute to
arbitration. The arbitrator shall determine what discovery will be permitted, consistent with the
goal of limiting the cost and time which the Parties must expend for discovery; provided that the
arbitrator shall permit such discovery as he or she deems necessary to permit an equitable
resolution of the Dispute.

          (c) The Parties agree that the decision of the arbitrator shall be the sole,
exclusive and binding remedy between them regarding the Dispute presented to the arbitrator. Any
decision of the arbitrator may be entered in a court of competent jurisdiction for judicial
recognition of the decision and an order of enforcement. The arbitration proceedings and the
decision of the arbitrator shall not be made public without the joint consent of the Parties and
each Party shall maintain the confidentiality of such proceedings and decision unless each Party
otherwise agrees in writing; provided that either Party may make such disclosures as are permitted
for Proprietary Information of the other Party under Article X above.

          (d) Unless otherwise mutually agreed upon by the Parties, the arbitration
proceedings shall be conducted in San Diego, California. The Parties agree that they shall share
equally the cost of the arbitration filing and hearing fees, the cost of the independent expert
retained by the arbitrator, and the cost of the arbitrator and administrative fees of JAMS. Each
Party shall bear its own costs and attorneys’ and witnesses’ fees and associated costs and
expenses.

          (e) Pending the selection of the arbitrator or pending the arbitrator’s
determination of the merits of any Dispute, either Party may seek appropriate interim or
provisional relief from any court of competent jurisdiction as necessary to protect the rights or
property of that Party.

     15.7 LIMITATION OF LIABILITY. EXCEPT FOR A BREACH OF ARTICLE X (CONFIDENTIALITY),
NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY PUNITIVE, SPECIAL, CONSEQUENTIAL, INCIDENTAL OR
INDIRECT DAMAGES ARISING OUT OF THIS AGREEMENT, HOWEVER CAUSED, UNDER ANY THEORY OF LIABILITY;
PROVIDED HOWEVER THAT NOTHING IN THIS SECTION 15.7 SHALL BE DEEMED TO LIMIT THE INDEMNIFICATION
OBLIGATIONS OF EITHER PARTY UNDER ARTICLE XIV TO THE EXTENT A THIRD PARTY RECOVERS ANY PUNITIVE,
SPECIAL, CONSEQUENTIAL, INCIDENTAL OR INDIRECT DAMAGES FROM AN INDEMNITEE.

     15.8 Entire Agreement. This Agreement (including the Exhibits attached hereto)
contains the entire agreement by the Parties with respect to the subject matter hereof and
supersedes any prior express

deemed to be followed by the phrase “without limitation” or like expression; (b) the singular shall
include the plural and vice versa; and (c) masculine, feminine and neuter pronouns and expressions

     15.10 Independent Contractors. It is expressly agreed that Biogen Idec and Covella
shall be independent contractors and that the relationship between the two Parties shall not
constitute a partnership, joint venture or agency or other fiduciary relationship. Neither Biogen
Idec nor Covella 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 to do so.

     15.11 Waiver; Amendment. Except as otherwise expressly provided in this Agreement,
any term of this Agreement may be waived only by a written instrument executed by a duly authorized
representative of the Party waiving compliance. The delay or failure of any Party at any time to
require performance of any provision of this Agreement shall in no manner affect such Party’s
rights at a later time to enforce the same. This Agreement may be amended, and any term of this
Agreement may be modified, only by a written instrument executed by a duly authorized
representative of each Party.

     15.12 Binding Effect. This Agreement shall be binding upon and inure to the benefit
of the Parties and their respective legal representatives, successors and permitted assigns.

2010 (the “Merger Agreement”) with Santarus and Lawrence C. Fritz as the
