Patent;

Whereas, a jury trial that commenced on November 6, 2006, resulted in the Verdict Form (Docket # 1006) filed

under action numbers HC 04 C 03940 and HC 05 C 00415 (the UK Proceedings);

Whereas, the Parties have determined
that it is in their mutual interest to avoid the expense, distraction, and uncertainty of further litigation and have therefore agreed to conclude and resolve all of their disputes under the Lawsuit and UK Proceedings and settle and consent to

assigns, from any and all claims, rights, demands, liabilities, obligations, damages, actions, and causes of action, of every kind and nature, in law, equity, or otherwise, known and unknown, suspected and unsuspected, disclosed and undisclosed,
arising out of any act, omission, event, transaction or occurrence on or before the Effective Date solely to the extent relating to both (a) a Product and (b) the GNE Patents; provided that this release shall not extend to and affect the
rights and obligations under the Permanent Injunction.

2.5 Release by Insmed. Insmed, by and for itself and on behalf of its
employees, agents, other representatives, sublicensees, officers, directors, stockholders, partners, members, subsidiaries, predecessors, successors, and assigns, irrevocably, perpetually and fully releases and discharges Tercica and GNE as well as
each of Tercicas and GNEs respective employees, agents, fill-finishers, customers, downstream sellers and users of Increlex, and Tercicas and GNEs other representatives, officers, directors, stockholders, partners, members,
subsidiaries, predecessors, successors, licensees, distributors, and assigns, from any and all claims, rights, demands, liabilities, obligations, damages, actions, and causes of action, of every kind and nature, in law, equity, or otherwise, known
and unknown, suspected and unsuspected, disclosed and undisclosed, arising out of any act, omission, event, transaction or occurrence on or before the Effective Date solely to the extent relating to both (a) the Insmed Patents and (b) any
Non-Permitted Products; provided that this release shall not affect the rights and obligations under the Permanent Injunction.

2.6
Waiver of Section 1542 of California Civil Code. Each of Tercica, GNE and Insmed hereby declares and acknowledges the contents of Section 1542 of the California Civil Code, and that section and the benefits thereof are hereby expressly
waived. Section 1542 provides as follows: A general release does not extend to claims which the creditor does not know or suspect to exist in his favor at the time of executing the release, which if known by him must have materially
affected his settlement with the debtor.

2.7 Other Waivers and Stipulations. The Parties hereby incorporate by reference the
conclusions of law, the findings of fact, waivers and stipulations set forth in the Permanent Injunction.

2.8 Discontinuance of UK
Proceedings. The Parties shall promptly and permanently discontinue the claims and counterclaims in the UK Proceedings, on the basis that each Party shall be responsible for the costs incurred by it in connection with those proceedings (other
than costs which have already been paid by one Party to another pursuant to an order of the United Kingdom Court made prior to the Effective Date). The Parties shall accordingly enter into and perform the UK Proceedings Settlement Agreement
relating to the UK Proceedings in the form of Exhibit C forthwith following the execution of this Agreement. Insmed shall ensure that Avecia shall, and shall cause Avecia to, execute such settlement agreement and do all such acts and
execute all such documents as may be necessary or desirable to give effect to the provisions of such settlement agreement, including the discontinuance of the claims brought by Avecia against Tercica and GNE in the course of the UK Proceedings.

anything to the contrary in this Section 2.8, as between Tercica and GNE, Tercica shall absorb and bear sole responsibility for payment of any fees,
costs, and expenses incurred by GNE relating to the prosecution and/or defense of the Lawsuit and/or the UK Proceedings (with the exception of the time and expenses of any GNE employee(s) allocated or attributed to such prosecution and/or defense,
which costs shall be borne by GNE).

2.9 Survival of this Article 2. The Parties hereby agree and acknowledge that the releases,
waivers, and covenants made in this Article 2 shall survive the expiration or any termination of this Agreement, including any termination based on a claim by a Party that another Party has breached this Agreement, the Permanent Injunction or the UK
Proceedings Settlement Agreement and any such breach shall not be construed as evidence of a failure of consideration for the granting of the releases, waivers and covenants set forth in this Article 2.

ARTICLE 3

LICENSE GRANTS

3.1 Licenses to Insmed.

(a) Limited License for Non-Permitted Indications in the United States. Subject to the terms and conditions of this Agreement, including without limitation Insmeds fulfillment of its royalty obligations under Section 7.1
below and Insmeds continued compliance with its covenants in Section 3.5 and the Permanent Injunction and the UK Proceedings Settlement Agreement, Tercica hereby grants Insmed a non-exclusive, non-sublicenseable license or sublicense, as
applicable, under Tercicas entire right, title and interest in and to the Licensed Patents to make, have made, use, sell, offer for sale, and import Product for sale in the United States for any Non-Permitted Indication solely for the
continuing treatment of any Existing Patient, for a period of twelve (12) months from the Effective Date. Existing Patient means no more than one hundred ten (110) patients for whom a Product is prescribed for a

respect to Net Sales arising from sales to the Existing Patients during the first three (3) months after the Effective Date. If any such sales to Existing Patients occur after such three (3)-month period, such sales shall be royalty-bearing
pursuant to Section 7.1(a)(i), but only until the date which is twelve (12) months after the Effective Date. Any sales of a Product by Insmed to such Existing Patients after such twelve (12)-month period, or any sales of a Product by
Insmed to any patient who is not an Existing Patient for the treatment of any Non-Permitted Indication at any time after the Effective Date, shall be evidence of Material Breach by Insmed of this Section 3.1(a) and/or a violation of the
Permanent Injunction, and Tercica may take any action and/or seek any remedy in law or equity for such breach or violation.

(b) License
for Named Patient Indications in the European Union on Named Patient Basis. Subject to the terms and conditions of this Agreement, including without limitation Insmeds fulfillment of its royalty obligations under Section 7.1 below,

sublicenseable, royalty-bearing license, or sublicense, as applicable, under Tercicas entire right, title and interest in and to the Licensed Patents
to make, have made, use, sell, offer for sale, and import Product for sale in any country in the European Union solely for the treatment of one or more of the Named Patient Indications, on a Named Patient Basis only; provided that Tercica and GNE
each shall have the right to perform audits, either by itself or through its designee, on Insmeds compliance with any laws, regulations and guidelines applicable to conducting such activities on a Named Patient Basis in addition to, and
pursuant to the procedures described in, Section 7.8.

(c) License for Permitted Indications in the Territory. Subject to the
terms and conditions of this Agreement, including without limitation the exclusion of rights and restrictive covenants set forth in Section 3.1(e), Tercicas and GNEs Opt-In rights described in Section 4.2, Insmeds royalty
obligations under Section 7.1 below, and Insmeds continued compliance with its covenants in Section 3.5 and the Permanent Injunction and UK Proceedings Settlement Agreement, Tercica hereby grants Insmed a non-exclusive,
royalty-bearing license, or sublicense, as applicable, with the right to sublicense solely as permitted under this Section 3.1(c), under Tercicas entire right, title and interest in and to the Licensed Patents to make, have made, use,
sell, offer for sale, and import Product for sale in all countries in the Territory, solely for use in the treatment of any of the Permitted Indications. Subject to Tercicas and GNEs Opt-In rights under Section 4.2, the license
granted in this Section 3.1(c) may be sublicensed by Insmed to Third Parties with the prior written consent of Tercica and GNE, such consent not to be unreasonably withheld or delayed.

(d) Limited Covenant-Not-To-Sue for ALS Indication on Named Patient Basis in Italy. Subject to the terms and conditions of this Agreement,
including without limitation Insmeds fulfillment of its royalty obligations to GNE under Section 7.1 below, and Insmeds continued compliance with its covenants in Section 3.5 and the Permanent Injunction and UK Proceedings
Settlement Agreement, each of GNE and Tercica hereby covenants that it shall not, to the extent it has the right to do so, enforce, or permit or encourage the enforcement of, against Insmed or its Affiliates any Licensed Patents in connection with
the making, having made and using of a Product for the limited purpose of: (i) using, selling, offering for sale, and importing Product for sale in Italy solely for the treatment of ALS on a Named Patient Basis only; provided that each of
Tercica and GNE shall have the right to perform audits, either by itself or through its designee, on Insmeds compliance with any laws, regulations and guidelines applicable to conducting such activities on a Named Patient Basis in addition to,
and pursuant to the procedures described in, Section 7.8, and (ii) conducting a single non-pivotal clinical trial (i.e., such clinical trial cannot and shall not be used to support regulatory filing or application for Marketing
Authorizations anywhere in the Territory), for the ALS indication in Italy, in connection with Insmeds treating patients in Italy for the ALS indication on a Named Patient Basis. For the avoidance of doubt, and notwithstanding the payment of
royalties solely to GNE pursuant to Section 7.1(a)(iii) based upon Insmeds sales under this Section 3.1(d) and Tercicas audit rights set forth in this Section 7.1(d), each of Tercica and GNE reserves the right to its
respective interpretation of the GNE Licenses as to whether the scope of the GNE Licenses includes a grant of rights to the ALS indication by GNE to Tercica.

(e) Diabetes Restriction in the Other Territory. Insmed hereby covenants that, notwithstanding the license grant in Section 3.1(c), it will not market, sell, offer for sale or

have sold a Product for Diabetes in the Other Territory to the extent the manufacture, use or sale of such Product would infringe, in the Other Territory and
if not for the licenses granted under this Agreement, the patent rights licensed to Tercica and sublicensed to Insmed under the GNE Licenses.

(f) Included Subsidiary Rights. For avoidance of doubt, the above licenses and limited covenant-not-to-sue granted in Sections 3.1(a) through (d) relating to a Product include the right to make (and have made) IGF-1 and IGFBP-3,
solely for use in the manufacture of Product, but such licenses do not include the right to use, sell, offer for sale or import either IGF-1 or IGFBP-3 separately.

3.2 Rights Granted to Tercica and GNE.

(a) Covenant not to Sue. Insmed hereby covenants that
it shall not enforce, or permit or encourage the enforcement of, against Tercica, GNE or Ipsen, or any of their respective Affiliates, sublicensees, successors or assigns any Insmed Patents in connection with the development or commercialization of
any Non-Permitted Product in the Territory, and in the event Insmed transfers any right under such Insmed Patents to a Third Party, Insmed shall ensure that such covenant not to sue is binding upon such Third Party in writing.

(b) License in the Event of an Opt-In. In the event Tercica and/or GNE exercises its Opt-In right with respect to a given Permitted Indication
pursuant to Section 4.2 below, Insmed hereby grants such Opt-In Party a non-exclusive, worldwide license, with the right to grant sublicenses as provided in this Section 3.2(b), under the Insmed Patents to make, have made, use, sell, offer
for sale and import Product for the Opt-In Indication as and to the extent permitted under this Agreement. Any sublicense by Tercica or GNE (or their assignees as permitted under Section 4.2(a)) under the rights granted in this
Section 3.2(b) to a sublicensee other than a distributor, subcontractor or consultant in the normal course of business shall be made by Tercica or GNE only with the consent of Insmed, such consent not to be unreasonably withheld, provided
however that sublicenses to Ipsen shall not require the consent of Insmed. In addition, Insmed agrees to execute all documents as may be reasonably required by Tercica or GNE or Ipsen or their authorized sublicensees for the purpose of recording any
such sublicense(s) with any relevant regulatory or administrative authorities and in the event Insmed transfers any right in the affected Insmed Patents to a Third Party, Insmed shall ensure that such Third Party is bound, in writing, by the
obligation set forth in this sentence.

3.3 GNE Licenses. The Parties acknowledge that the license granted to Insmed under
Section 3.1 above constitutes a sublicense with respect to the GNE Patents under the licenses granted to Tercica by GNE under the GNE Licenses. As a result, the licenses granted under Section 3.1 above, and the terms and conditions of this
Agreement, shall be subject to the terms and conditions of the GNE Licenses. GNE hereby agrees to the granting of such sublicense to Insmed by Tercica as set forth in Section 3.1. Nothing in this Agreement shall be construed as: (a) the
expansion or reduction of the scope of licenses Tercica received from GNE under the GNE Licenses; or (b) implying whether or not the license granted to Tercica under the GNE Agreements includes the ALS indication.

3.4 No Implied Licenses. Except as explicitly set forth in this Agreement, no Party grants any
license, express or implied, under its intellectual property rights to any other Party. Each Party covenants that it will not use or practice any other Partys intellectual property rights licensed to it under this Agreement except for the
purposes expressly permitted in the applicable license grant.

3.5 Insmed Covenants. In light of the Lawsuit and the Damages awarded
therein, and in consideration of the licenses granted by Tercica and GNE to Insmed in Section 3.1, Insmed hereby covenants the following (which covenants shall be in addition to those set forth in the Permanent Injunction):

(a) Insmed shall not, and shall cause its Affiliates and Sublicensees to not, directly or indirectly: (i) conduct clinical trials for or
otherwise seek any Marketing Authorization for, promote, market, or knowingly sell or offer for sale a Product for the treatment of any Non-Permitted Indication in any country in the Other Territory except as expressly permitted under
Section 3.1(b) above with respect to the Named Patient Indications on a Named Patient Basis and Section 3.1(d) above with respect to the ALS indication on a Named Patient Basis, for so long as (A) any such clinical trial or Marketing
Authorization uses or depends on the supply of such Product manufactured in a country in which such manufacture is covered by any unexpired Licensed Patents in such country, (B) any such promotion, marketing, sale or offer for sale of such
Product depends on the supply of such Product manufactured in a country in which such manufacture is covered by any unexpired Licensed Patents in such country, or (C) any such promotion, marketing, sale or offer for sale of such Product arises
from or depends on the use, sale, offer for sale, or importation of such Product in a country in which such use, sale, offer for sale, or importation is covered by any unexpired Licensed Patents in such country. For purposes of determining the
duration of such covenant in countries in the Other Territory where a Product is sold which is manufactured in the United States, the last to expire Licensed Patents with respect to such countries shall include U.S. Patent No. 6,331,414 to the
extent such patent covers the manufacture of the Product sold (or any components thereof).

(b) Within fifteen (15) business
days after the Effective Date, Insmed shall withdraw, or cause to be withdrawn, all currently pending applications for Marketing Authorization in the Other Territory, including specifically its currently pending application for Marketing
Authorization with the EMEA for a Product for the treatment of primary IGF-1 deficiency and patients with growth hormone gene deletion.

(c) Insmed shall not apply for or submit an application with the EMEA or any other governmental authority within the European Union or anywhere else in the Other Territory for Marketing Authorization of a Product for any of the
Non-Permitted Indications; provided, however, that for any such Marketing Authorization the foregoing covenant shall terminate upon the expiration of the last to expire Licensed Patents (i) that exists in a country in the European Union or the
Other Territory and that covers the manufacture, use, sale, offer for sale, or importation of such Product to be performed under the license of the Marketing Authorization, or (ii) that exists in a country in the Territory and that covers the
process by which such Product is manufactured in such country for subsequent use, sale, offer for sale, or importation in the European Union or other country in the Other Territory under the license of the Marketing Authorization.

(d) If Insmed or its Affiliates or Sublicensees challenge(s) the validity or enforceability of the
Licensed Patents anywhere in the Territory, then either Tercica or GNE shall have the right to terminate the licenses granted to Insmed under Section 3.1 of this Agreement pursuant to Section 12.3(a)(i) below.

3.6 Non-Disparagement. Insmed, Tercica and GNE each shall not defame, libel, slander or otherwise disparage in any manner, or tortiously interfere
with the business, contracts, relationships or prospective economic advantage appurtenant to: (a) the market opportunity for any product (e.g., the size of the market for severe Primary IGFD); or (b) any product of the other Parties.

ARTICLE 4

DEVELOPMENT AND OPT-IN RIGHTS

4.1 Development of Product Prior to Opt-In. Unless and until Tercica or GNE exercises
its Opt-In right under Section 4.2 below, Insmed shall have the sole responsibility for the development of a Product for use in a given Permitted Indication. As between the Parties to this Agreement, Insmed shall bear all Development Costs
incurred with respect to a Product for all Permitted Indications prior to the Opt-in Effective Date, subject to the Opt-In Partys reimbursement of a portion of such Development Costs pursuant to Section 4.2(e) below.

4.2 GNE and Tercicas Opt-In Right for Permitted Indications.

(a) General. Tercica and GNE shall each have the option to co-develop a Product for any particular Permitted Indication at any time during the period when such Product is being developed clinically for such
Permitted Indication, until the end of the Opt-In Period for such Permitted Indication. Such co-development right, once exercised, allows Tercica or GNE as the Opt-In Party to fund 50% (such percentage, the Percentage Interest) of
the Development Costs for a Product for such Permitted Indication and participate in a corresponding 50% portion of the Operating Profit (Loss) resulting from the commercialization of such Product for such Permitted Indication, participate in
development decision-making, and participate in commercialization, all as and to the extent set forth below and in Article 5 (the Opt-In). It is understood and agreed that Insmed shall not enter into any agreement with a Third
Party to develop or commercialize a Product for any Permitted Indication prior to the expiration of the Opt-In Period for such Permitted Indication. It is further understood and agreed that Tercica shall have the right to assign to Ipsen its Opt-In
rights and obligations with respect to the ROW Territory or certain country(ies) within such ROW Territory, as well as its Co-Promotion Option and Sole Promotion Option, on a Permitted Indication-by-Permitted Indication basis, in which case
reference to Tercica as used in this Section 4.2 and in Sections 4.3 and 4.4, and in Article 5, shall also include Ipsen. It is also further understood and agreed that GNE shall have the right to assign to a Third Party designee its
Opt-In rights and obligations with respect to the ROW Territory or certain country(ies) within such ROW Territory, as well as its Co-Promotion Option and Sole Promotion Option, on a Permitted Indication-by-Permitted Indication basis, subject to
Insmeds consent, not to be unreasonably withheld, in which case reference to GNE as used in this Section 4.2 and in Sections 4.3 and 4.4, and in Article 5, shall also include such Third Party designee.

ACT OF 1934, AS AMENDED.



---

(b) Opt-In Period; Effectiveness. Tercicas and GNEs Opt-In rights shall commence, on a
Permitted Indication by Permitted Indication basis, at the commencement of the first human clinical trials of a Product for such Permitted Indication, and shall terminate on the earlier of: (i) exercise by Tercica or GNE of such Opt-In, or
(ii) 91 days after the Triggering Delivery for such Permitted Indication without exercise by either GNE or Tercica of its Opt-In rights (the Opt-In Period for such Permitted Indication), as described in more detail in this
Section 4.2. For the avoidance of doubt, Tercica and GNE may exercise their respective Opt-In rights at any time during the Opt-In Period in accordance with this Section 4.2 by providing written notice to Insmed of the same (such notice,
the Opt-In Exercise Notice). Insmed shall promptly submit a written confirmation to the Party whose Opt-In Exercise Notice has been received (unless otherwise properly rejected as not being properly submitted by the potential
Opt-In Party pursuant to this Section 4.2), along with an invoice detailing the amount of the Opt-In Payment due Insmed. Such Opt-In shall become effective upon receipt by Insmed of such Opt-In Payment (the Opt-In Effective
Date). At the Opt-In Effective Date, the Party having submitted such Opt-In Exercise Notice shall thereupon become an Opt-In Party and such Permitted Indication shall become an Opt-In Indication.

(c) Opt-In Information; Triggering Delivery. On a regular basis but no less frequently than once per calendar quarter, Insmed shall
provide to Tercica and GNE a written progress report setting forth, for each Permitted Indication then undergoing development and as to which the Opt-In rights have not been exercised or lapsed: (i) a summary of all clinical trials planned and
actually conducted, as well as all results thereof, for a Product for treatment of each such Permitted Indication; (ii) all Opt-In Information that has not been previously disclosed to either Tercica or GNE as of such time; and (iii) a
summary of all Development Costs incurred as of such time with respect to such Permitted Indication. In particular, and notwithstanding such quarterly reporting obligation, Insmed shall, within sixty (60) days after the Completion of the first
Phase III Enabling Trial for a Product for such Permitted Indication, deliver to Tercica and GNE all Opt-In Information relating to such trial and any other Opt-In Information that has not been previously disclosed to either Tercica or GNE, as well
as a summary of all Development Costs incurred as of such time with respect to such Permitted Indication (this delivery of such Opt-in Information and Development Cost information is the Triggering Delivery). Tercica and GNE shall
use the Opt-In Information solely for the purpose of evaluating the Opt-In opportunity and such Opt-In Information and shall not disclose any non-public portion of such Opt-In Information to any Third Party without the prior written consent of
Insmed. Following delivery of any such Opt-in Information and Development Cost information, Insmed shall promptly supply any additional information or respond to any questions as requested by GNE or Tercica based upon its review of such information.
Upon the expiration of the Opt-In Period, each of GNE and Tercica shall return such Opt-In Information to Insmed if such Party has not exercised its Opt-In right under this Section 4.2.

(d) Opt-In Rights and Procedures.

(i) During the Opt-In Period, Tercica shall have the first right to exercise the Opt-In right throughout the Territory with respect to any Orphan Indication that is not a Diabetes Orphan Indication. In the event Tercica does not so
exercise such right within sixty (60) days of the Triggering Delivery, it shall notify Insmed and GNE in writing. Upon receipt of such written notice, GNE shall have an additional period of thirty (30) days following

AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE

---

the date of such notice by Tercica to elect to exercise the Opt-In right with respect to such Orphan Indication. For avoidance of doubt, this Opt-In right
shall expire upon the first to occur of the exercise of the Opt-In Right, or ninety one (91) days after the Triggering Delivery.

(ii) During the Opt-In Period, GNE shall have the first right to exercise the Opt-In right with respect to (1) any Non-Orphan Indications throughout the Territory and (2) any Diabetes Orphan Indication in the United States.
In the event GNE does not so exercise such right within sixty (60) days of the Triggering Delivery, it shall notify Insmed and Tercica in writing. Whereupon Tercica shall have an additional period of thirty (30) days following the date of
such notice by GNE to elect to exercise the Opt-In right with respect to such Non-Orphan Indication or such Diabetes Orphan Indication. For avoidance of doubt, this Opt-In right shall expire upon the first to occur of the exercise of the Opt-In
Right, or ninety one (91) days after the Triggering Delivery.

(iii) If either Tercica or GNE provides Insmed with the Opt-In
Exercise Notice within the Opt-In Period, then Insmed shall enter into a co-development and, where such Opt-in Party so elects under Section 5.2, co-commercialization relationship with the Party providing Insmed with such notice, on the terms
set forth in this Article 4 and in Article 5.

(e) Opt-In Payment; Accounting of Development Costs. The Opt-In
Payment for a Product for a particular Permitted Indication shall be an amount equal to fifty percent (50%) of the total Development Costs allocable to the development of such Product for such Permitted Indication, and incurred as of
the date of receipt of the Opt-In Exercise Notice for such Permitted Indication. Such Opt-In Payment shall be paid to Insmed in accordance with Section 4.2(b). All Development Costs incurred and allocable to any Permitted Indication as of the
Effective Date will be provided, in writing, on a Permitted Indication-by-Permitted Indication basis, by Insmed to Tercica and GNE within thirty (30) days following the Effective Date. During the Term and prior to the expiration of the Opt-In
Period, Insmed shall be responsible for maintaining a detailed account of all Development Costs expended for each Permitted Indication.

4.3 Consequences of Tercica or GNEs Exercise of Opt-In. If Tercica or GNE exercises the Opt-In in accordance with Section 4.2, the following shall apply:

(a) Collaborative Development. Insmed and the Opt-In Party shall discuss, via the JDC, what if any operational matters in the development of a
Product for such Opt-In Indication shall be the responsibility of the Opt-In Party.

(b) Ongoing Co-Funding of Development Costs.
The Opt-In Party shall bear fifty percent (50%) of the total Development Costs incurred from the day after the date of receipt of the Opt-In Exercise Notice for such Permitted Indication and allocable to the development of a Product for such
Opt-In Indication. The process for reconciling payment of such Development Costs in order to give effect to each Opt-In Partys Percentage Interest shall be in accordance with Article 7 and Exhibit A.

(c) Decision-Making Control. The Opt-In Party may have the deciding vote with respect to decisions in the JDC regarding such Opt-In Indication, as
provided in Section 6.2(d)(ii).

(d) Right for GNE to Develop and Commercialize Diabetes. In the event that GNE is the Opt-In Party
and the Opt-In Indication is a Diabetes Orphan Indication (an Opt-In Diabetes Orphan Indication), at such time, if any, as GNE and Insmed using their respective scientific and business judgment disagree over whether the continued
development of a Product for the Opt-In Diabetes Orphan Indication is desirable (such that Insmed does not wish to continue development of such Product for the Opt-In Diabetes Orphan Indication), GNE may elect to take over the development of such
Product for the Opt-In Diabetes Orphan Indication at the sole expense of GNE and, upon notice to Insmed of such election, the Permitted Indications shall be amended to exclude such Opt-In Diabetes Orphan Indication solely for the purposes of the
rights granted to Insmed under Section 3.1(c), provided that:

(i) for all other purposes of this Agreement, including without
limitation the licenses granted by Insmed to GNE as the Opt-In Party under Section 3.2(b), the Permitted Indications shall be deemed to include such Opt-In Diabetes Orphan Indication;

(ii) GNE shall become, if not already, the Booking Party for such Opt-In Diabetes Orphan Indication and shall have final decision making
authority in the commercialization of such Product for such Opt-In Diabetes Orphan Indication in the United States; and

(iii) the
profit-sharing arrangement applicable to such Opt-In Diabetes Orphan Indication shall continue only until the payments so received by Insmed from GNE equals the Development Costs incurred by Insmed for such Product for such Opt-In Diabetes Orphan
Indication, and thereafter the profit share arrangement for such Opt-In Diabetes Orphan Indication shall terminate and GNE shall pay to Insmed royalties on the Net Sales for such Opt-In Diabetes Orphan Indication in the United States at a rate of [
* ]; provided that, such royalty payment obligation shall apply only in the event that the use, sale, offer for sale, or importation of such Product for use in the Opt-In Diabetes Orphan Indication would infringe the Insmed Patents, and such royalty
payment obligation shall thereafter expire upon the later of (y) the expiration of the last to expire Insmed Patents existing in the United States that would be infringed by the use, sale, offer for sale, or importation of such Product for use
in such Opt-In Diabetes Orphan Indication in the United States but for the license grant in Section 3.2(b), and (z) the expiration of the last to expire Insmed Patents existing in a country and that covers the actual method of manufacture
or use of such Product (or component thereof) as practiced by Insmed in the manufacture of such Product in such country that is subsequently sold for use in such Opt-In Diabetes Orphan Indication in the United States.

(e) Ongoing Sharing of Profits and Losses. As further described in Section 7.2, Insmed and the Opt-In Party shall share Operating Profit
(Loss) with respect to a given Opt-In Indication, based on the applicable Percentage Interest for such Opt-In Indication.

(f) Opt-In
Partys Product Commercialization Rights for Opt-In Indication. If either Tercica or GNE exercises the Opt-In right under this Section 4.2, such Party shall have the right, at its discretion, to exercise the Sole Promotion Option or
the Co-Promotion Option for the respective Opt-In Indication pursuant to Section 5.2. In addition, following such exercise of the Opt-In right, Insmed shall have no right to seek, negotiate or enter

into an agreement with, a Third Party partner for the co-development and/or co-commercialization of a Product.

4.4 Opt-Out Rights. An Opt-In Party for a particular Opt-In Indication shall have the right to discontinue its ongoing funding obligations for
such Opt-In Indication either in total or on a region-by-region or country-by-country basis in the Territory (the term region means and includes each of the following: the North American Territory, the EU, and Japan) for such Opt-In
Indication, for any or no reason, for a period of ten (10) business days after the completion of an ongoing clinical trial and the reporting of results from such clinical trial for a Product for the treatment of such Opt-In Indication (the
Opt-Out). An Opt-In Party may exercise such Opt-Out right by providing written notice to Insmed stating the same. Effective thirty (30) days following notice of such Opt-Out: (a) such Party shall cease to be an Opt-In
Party and the license granted under Section 3.2(b) for such Permitted Indication shall terminate, (b) such Party shall have no further obligation to co-fund the ongoing Development Costs of such Product for such Permitted Indication other
than for non-cancelable out-of-pocket costs incurred or committed to as of the effective date of the Opt-Out for activities previously approved in accordance herewith, (c) such Party shall have no right to share in a portion of the Operating
Profits (Loss) for such Product for such Permitted Indication, (d) such Permitted Indication shall cease to be an Opt-In Indication, (e) such Party shall no longer have the Sole Promotion Option or Co-Promotion Option with respect to such
Permitted Indication, and (f) such Party shall nor longer have any decision making control or input with respect to the development or commercialization of such Product for such Permitted Indication. If Insmed continues the development and/or
commercialization of such Product for such Permitted Indication thereafter, then such Opt-In Party, after exercising its Opt-Out right, shall receive a royalty on the Net Sales of a Product for treatment of such Permitted Indication as further
described in Section 7.1(a)(ii). For clarity, if an Opt-In Party exercises the Opt-Out right, it shall not have any right to a refund or reimbursement of any payments it had made to co-fund the Development Costs for a Product for such Permitted
Indication.

ARTICLE 5

COMMERCIALIZATION

5.1 Commercialization by Insmed. Insmed shall have the primary right and responsibility for
commercializing a Product for a given Permitted Indication; provided, however, that if the Opt-In Party for a particular Opt-In Indication elects to exercise its Co-Promotion Option or Sole Promotion Option for such Opt-In Indication, then the
Parties shall proceed as set forth in this Article 5 and the terms of the Co-Promotion Agreement (as defined in Section 5.3) or the terms of the Supply Agreement (as defined in Section 5.4) shall apply to the commercialization of such
Product for the treatment of such Opt-In Indication.

5.2 Commercialization by an Opt-In Party. Subject to the proper exercise of
the Opt-In right described in Section 4.2, Insmed hereby grants the Opt-In Party, for the corresponding Opt-In Indication: (a) an option to co-promote, worldwide, a Product with Insmed for the treatment of such Opt-In Indication (the
Co-Promotion Option); and (b) an option to assume sole responsibility for the commercialization of a Product for the treatment of such Opt-In Indication (the Sole Promotion Option). It is further understood
and agreed that Tercica

shall have the right to assign to Ipsen such Co-Promotion Option or Sole Promotion Option with respect to the ROW Territory or certain country(ies) within
such ROW Territory, in which case the Opt-In Party as used in this Article 5 shall also include Ipsen. It is also further understood and agreed that GNE shall have the right to assign to a Third Party designee such Co-Promotion Option or
Sole Promotion Option with respect to the ROW Territory or certain country(ies) within such ROW Territory, in which case the Opt-In Party as used in this Article 5 shall also include such Third Party designee.

5.3 Opt-In Partys Co-Promotion Option for Product for an Opt-In Indication.

(a) Exercise of Co-Promotion Option. The Opt-In Party may exercise the Co-Promotion Option as to an Opt-In Indication by providing written notice
to Insmed within sixty (60) days following the JDCs decision (as set forth in approved minutes of the JDC) to file the first application for Marketing Authorization for a Product for such Opt-In Indication in a given country. It is
understood that such Co-Promotion Option shall be triggered with respect to the North American Territory and the ROW Territory independently, such that if, by way of example, the Opt-In Party does not exercise its Co-Promotion Option for the North
American Territory (or part thereof), it may nonetheless exercise its Co-Promotion Option for the ROW Territory (or part thereof), provided such Opt-In Party has not exercised its right to Opt-Out of co-development for any such North American
Territory or ROW Territory. If the Opt-In Party exercises the Co-Promotion Option, the Opt-In Party shall co-promote such Product for the treatment of such Opt-In Indication with Insmed, during the Co-Promotion Term pursuant to the terms of a
Co-Promotion Agreement, as further described in Section 5.3(b) below. Co-promotion of Product for the treatment of such Opt-In Indication shall be overseen and coordinated by the JCC.

(b) Co-Promotion Agreement. Promptly following the Opt-In Partys exercise of the Co-Promotion Option with respect to a particular Opt-In
Indication in a region or country, the Opt-In Party and Insmed shall engage in good faith negotiations to prepare and execute a definitive co-promotion agreement describing the co-promotion activities of the Parties for promoting a Product for the
treatment of such Opt-In Indication in such region or country (the Co-Promotion Agreement). The Co-Promotion Agreement will have the terms and conditions set forth in this Article 5 and in the term sheet attached to this Agreement
as Exhibit E, as well as such other terms as the Opt-In Party and Insmed may agree. The Opt-In Party and Insmed will use reasonably diligent efforts to execute the Co-Promotion Agreement at least twelve (12) months prior to the
anticipated receipt of Marketing Authorization for such Product for such Opt-In Indication as determined by the JCC (such date, the Launch Date) for the treatment of such Permitted Indication in the relevant jurisdiction. The
Co-Promotion Term will commence upon execution of the Co-Promotion Agreement and will extend for so long as Insmed is selling a Product or the termination of this Agreement, whichever occurs first.

(c) Commercialization Plan. If the Opt-In Party exercises its Co-Promotion Option with respect to a particular Opt-In Indication, the strategy and
tactics for the commercial launch of a Product for the Opt-In Indication shall be described in a comprehensive plan that describes the launch and subsequent co-promotion and related commercialization activities for such Product by the Opt-In Party
and Insmed (including advertising, education, planning, marketing, sales force training and detail allocation) (the Commercialization Plan). The

---

JCC shall prepare an initial draft of the Commercialization Plan within one (1) month after the filing of the first application for Marketing
Authorization and shall approve a final Commercialization Plan at least six (6) months prior to the anticipated Launch Date for such Product for the treatment of such Opt-In Indication. The JCC shall update such Commercialization Plan as needed
thereafter, but in any event annually.

5.4 The Opt-In Partys Sole Promotion Option for Product for an Opt-In Indication.

(a) Exercise of Sole Promotion Option. The Opt-In Party may exercise the Sole Promotion Option for each of its Opt-In
Indications by providing written notice to Insmed within sixty (60) days following the JDCs decision (as set forth in approved minutes of the JDC) to file an application for Marketing Authorization for a Product for such Opt-In Indication
in a given country. It is understood that such Sole Promotion Option shall be triggered with respect to the North American Territory and the ROW Territory independently, such that if, by way of example, the Opt-In Party does not exercise its Sole
Promotion Option for the North American Territory (or part thereof), it may nonetheless exercise its Sole Promotion Option for the ROW Territory (or part thereof), provided such Opt-In Party has not exercised its right to Opt-Out of co-development
for any such North American Territory or ROW Territory or part thereof. If the Opt-In Party exercises the Sole Promotion Option, the Opt-In Party shall thereafter have the sole right to market, promote, sell, and offer for sale such Product for the
treatment of such Opt-In Indication, in the region or country(ies) as to which such option is exercised, including without limitation, the sole right to book all sales of such Product for such Opt-In Indication.

(b) Supply of Product by Insmed. Promptly following the Opt-In Partys exercise of the Sole Promotion Option, the Opt-In Party and Insmed
shall engage in good faith negotiations to prepare and execute a definitive supply agreement describing terms and conditions by which Insmed shall supply or cause to be supplied (by manufacturing itself or by procuring from a Third Party) commercial
quantities of finished, filled, and packaged Product to the Opt-In Party for such Opt-In Indication, at a price equal to Insmeds Fully Burdened Manufacturing Cost not to exceed $2,500/gram (such agreement, the Supply
Agreement). The Supply Agreement will set forth the terms and conditions as the Opt-In Party and Insmed may agree and as are customary in an agreement of that type, including without limitation, any supply capacity constraints for a
Product, forecasting and ordering, inspection and rejection provisions, and remedies in the event of supply default, including the ability of the Opt-In Party to make or have made a Product itself in such event. The Opt-In Party and Insmed will
negotiate and execute the Supply Agreement at least twelve (12) months prior to the anticipated Launch Date of a Product for the treatment of such Opt-In Indication.

(c) Trademark License. In the event Tercica and/or GNE exercises its Sole Promotion Option with respect to a given Opt-In Indication, Insmed hereby grants such Opt-In Party a non-exclusive, worldwide license,
with the right to grant sublicenses as provided in this Section 5.4(c), to use the Trademark in connection with the marketing, promotion and sale of a Product for use in the Opt-In Indication. Any sublicense by Tercica or GNE under the rights
granted in this Section 5.4(c) to a sublicensee other than Ipsen, or other than a distributor, subcontractor or consultant in the normal course of business, shall be made by Tercica or GNE only with the consent of Insmed, such consent not to be
unreasonably withheld. It is expressly



22

[  *  ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED
BY BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES
AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE
ACT OF 1934, AS AMENDED.



---

understood that the Opt-In Party exercising such Sole Promotion Option shall not be required to use the Trademark in connection with the marketing or sale of
a Product for such Opt-In Indication, but shall have the right to re-brand such Product for such Opt-In Indication under a new trademark, in which event the Opt-In Party shall own all rights in and to such new trademark and all associated goodwill.

5.5 Sales Tracking. The Parties recognize that, subject to the licenses granted in Section 3.1, and in light of the
Parties Opt-In rights with respect to given Permitted Indications, and Sole Promotion Option, a Product may be sold by Insmed for use in the treatment of one or more Permitted Indications as to which the Opt-In Party has exercised its rights,
as well as Permitted Indications as to which no Opt-In rights have been exercised, as well as to patients on a Named Patient Basis as provided in Section 3.1(b), and to Existing Patients under Section 3.1(a), and may also be sold by either
GNE or Tercica in the event of exercise of its Sole Promotion Option, for a given Opt-In Indication. In addition, Products marketed by Insmed (or its Sublicensee) or by GNE or Tercica (or their designee) in the future for an approved Permitted
Indication may nonetheless be prescribed for use in the treatment of one or more indications which are other than such approved Permitted Indication (i.e., Off Label Sales). Given that different financial consideration is due and owing
depending upon which of the foregoing situations is applicable (i.e., royalties vs. profit sharing), and in order to detect and account for such sales of Product in a manner most reflective of the Parties intent, the Parties agree as follows:

(a) Sales Tracking Methodology.

(i) Initial Methodology. Within one hundred eighty (180) days after the Effective Date, Tercica and Insmed shall meet and agree upon a method of tracking sales of Product for use in the treatment of each
indication, in the country sold (a Sales Tracking Methodology) including (1) the use of data from Statements of Medical Necessity, or the acquisition of one or more forms of prescription data (including by way of example, IMS
Xponent, NDCHealth Information Network, or Drug Distribution Data) or other relevant pharmaceutical sales tracking research services (including by way of example, audits of the corresponding statements of medical necessity, use of random sampling,
use of data regarding distribution channels as a proxy for indication-specific sales or development of mathematical models for approximating indication-specific sales) generally recognized in the pharmaceutical industry as having a reasonable degree
of accuracy and reliability in the tracking of sales of pharmaceutical products that have a similar nature as, and are prescribed by similar physicians as, a Product for the Named Patient Indications and Permitted Indications (the Data
Services), and (2) the methodology for applying any such resulting data and information provided by such Data Services to determine the extent of sales in each country which are attributable to each such indication. It is expressly
understood that sales of a Product for any Non-Permitted Indications are not anticipated except to the Existing Patients, and only for a period not to exceed twelve (12) months from the Effective Date, and any sales that are knowingly made to
patients for use within a Non-Permitted Indication by Insmed or its Affiliates or Sublicensees and that are tracked to any Non-Permitted Indications after such twelve (12) month period (or to any patients who are other than Existing Patients
within such twelve (12) month period) will be evidence of Insmeds breach of its covenant in Section 3.5 and its license under Section 3.1(a).



23

BY BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES
AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE
ACT OF 1934, AS AMENDED.



---

(ii) Modifications to Methodology. The JCC may elect at any point to adopt a different or
modified Sales Tracking Methodology, upon request of either Party. If the JCC fails to agree on a different Sales Tracking Methodology proposed by either Tercica or Insmed, the Sales Tracking Methodology then in effect shall continue to be used.
Notwithstanding the foregoing, it is understood and agreed by Tercica and Insmed that each shall have the right, at its own expense, to undertake such market research and analysis, including probes or sampling of patient data, physician
prescribing habits and the like (the New Sales Tracking Data) or otherwise propose modifications to the Sales Tracking Methodology at any time during the Term, and to present such data or otherwise propose modifications to the
Sales Tracking Methodology to the JCC to enhance the validity or reliability of the Sales Tracking Methodology. It shall be the JCCs continuing obligation to review any such New Sales Tracking Data in good faith, with the overriding obligation
to ensure fair and accurate compensation to the Parties (as applicable) under this Agreement by tracking as accurately as reasonably possible, purchases of a Product for use in specific indications. In the event that the JCC adopts a new Sales
Tracking Methodology that incorporates New Sales Tracking Data proposed by a Party, the costs of such new Sales Tracking Methodology shall be allocated between Tercica and Insmed as provided in Section 5.5(c).

(b) Implementation by Insmed. Promptly following the selection and adoption by the JCC of the Sales Tracking Methodology (and any new Sales
Tracking Methodology as applicable), Insmed hereby agrees to implement such Sales Tracking Methodology with respect to Insmeds annual worldwide sales of Product.

(c) Costs. Insmed and Tercica shall share equally all costs incurred in implementing the Sales Tracking Methodology until such time as GNE exercises its first Opt-In right, in which event all such costs shall
be shared equally between Insmed, Tercica and GNE.

(d) Dispute Resolution with Respect to Sales Tracking. Notwithstanding the
dispute resolution mechanism set forth in Article 13 below, the Parties agree that all disputes relating to matters pertaining to sales tracking, including without limitation the methodology(ies) to be used or implementation thereof, shall be
resolved as soon as practicable as follows: Any Party shall bring such dispute to the attention of the other Parties by providing the other Parties with a written notice stating such dispute, and the Parties shall use good faith efforts to resolve
such dispute through the JCC within thirty (30) days after the receipt of such notice. If the JCC cannot reach resolution on such matter during such thirty (30)-day period, then the matter shall be referred to the Chief Commercial Officer or
equivalent (or his/her designee who has decision-making authority) of the Parties for resolution. If such executives cannot reach resolution on such matter within ten (10) business days, then the Parties shall refer the matter to the Sales
Tracking Panel (as defined below) for resolution, and the Sales Tracking Panels decision (which shall require the consent and agreement of 2 of the 3 panelists) on such matter shall be final and binding upon all Parties. Notwithstanding the
foregoing, GNE may, at its option, recuse itself from such disputes with respect to sales tracking at any time by providing the other Parties with written notice stating such election. Sales Tracking Panel shall mean a panel of
three experts, each of whom have experience in market research and intelligence gathering with respect to pharmaceutical products (e.g., former employees of IMS), and at least one of whom has experience in market research and drug distribution and
prescribing information collection involving specialty pharmaceuticals. The Parties shall appoint such experts serving on the Sales

Tracking Panel within thirty (30) days after the Effective Date through mutual agreement, and shall maintain the number of experts on such Sales
Tracking Panel during the Term.

ARTICLE 6

GOVERNANCE

6.1 Overview. The Parties desire to establish certain committees to facilitate
the sharing of information between the Parties and to coordinate the development and commercialization of a Product for the treatment of Permitted Indications (as applicable) and the implementation of the Sales Tracking Methodology. It is understood
and acknowledged by each Party that, subject to Tercicas and GNEs opt-in rights in Section 4.2, Insmed will be primarily responsible for the development and commercialization of a Product strictly in accordance with the licenses
granted by Tercica under Section 3.1.

6.2 Joint Development Committee.

(a) Formation; Composition. Within thirty (30) days after the Effective Date, the Parties shall establish a committee to oversee development
of a Product and to serve as a forum for sharing information regarding such development between the Parties (the JDC). Tercica and Insmed each shall initially appoint three (3) representatives to the JDC, and GNE may
initially appoint up to three (3) representatives to the JDC. Following any exercise of its Opt-In rights, GNE shall appoint or retain at least one (1) representative, but no more than three (3) representatives, to the JDC. The JDC
may change its size from time to time by mutual consent of its members, provided that the JDC shall include at all times an equal number of representatives of each of Tercica, Insmed, and where GNE so elects, of GNE. Each Party may replace its JDC
representatives at any time upon written notice to the other Party(ies). The JDC may invite non-members to participate in the discussions and meetings of the JDC, provided that such participants shall have no voting authority at the JDC. The JDC
will be chaired by Insmed. The chairperson shall be responsible for administering JDC meetings, but shall have no additional powers or rights beyond those held by the other representatives of the JDC.

(b) Specific Responsibilities of the JDC. In addition to its general responsibilities, the JDC shall in particular:

(i) prior to an Opt-In Partys exercise of the Opt-In in accordance with Section 4.2 and throughout the Opt-In Period, facilitate the
flow of information from Insmed to Tercica and GNE with respect to the development of, and obtaining Marketing Authorization for, a Product for the treatment of any Permitted Indications;

(ii) prior to an Opt-In Partys exercise of the Opt-In in accordance with Section 4.2 and throughout the Opt-In Period, determine,
prior to the conduct of such trial, whether a proposed clinical trial for a Product satisfies the criteria of a Phase III Enabling Trial for the applicable Opt-In Indication; and

(iii) following an Opt-In Partys exercise of the Opt-In in accordance with Section 4.2
for a particular Permitted Indication, coordinate and oversee the Parties development of a Product for the treatment of the applicable Opt-In Indication.

(c) Meetings. The JDC shall meet at least once per calendar quarter after the Effective Date unless the Parties mutually agree in writing to a different frequency. The JDC may meet in person, by
videoconference, or by teleconference. The location of in-person JDC meetings will be held at locations alternately selected by Tercica, Insmed, and GNE. Each Party shall report to the JDC on all material issues relating to the development of a
Product promptly after such issues arise. Each Party will bear the expense of its respective JDC members participation in JDC meetings. Meetings of the JDC shall be effective only if at least one representative of each Party having incumbent
member(s) of the JDC is present or participating in such meeting. The chairperson of the JDC shall be responsible for keeping reasonably detailed written minutes of all JDC meetings that reflect, without limitation, material decisions made at such
meetings. Meeting minutes will be sent to each member of the JDC for review and approval within ten (10) business days after a meeting.

(d) Decision-Making. The JDC shall act by consensus. The representatives from each Party will have, collectively, one (1) vote on behalf of that Party. If the JDC cannot reach consensus on any issue that comes before the JDC,
then:

(i) prior to Tercicas or GNEs exercise of the Opt-In in accordance with Section 4.2, Insmed shall have the
deciding vote for all issues to be determined by the JDC; and

(ii) following the date when an Opt-In Party exercises its Opt-In
rights, such Opt-In Party would have the deciding vote on all matters related to the Opt-In Indication before the JDC.

It is expressly understood and
agreed that the control of decision-making authority by a Party so as to resolve a disagreement or deadlock at the JDC for any matter will not relieve such Party from any of its representations, warranties, or covenants in this Agreement, nor will
it enable such Party to unilaterally modify or amend the terms of this Agreement.

6.3 Joint Commercialization Committee.

(a) Formation; Composition. Promptly following the Effective Date but in no event later than thirty (30) days after the
Effective Date, the Parties shall form a committee to, in the first instance agree upon and approve the Sales Tracking Methodology, and, following exercise by an Opt-In Party of its Co-Promotion Option or Sole Promotion Option, coordinate and
oversee the Parties respective commercialization activities with respect to a Product for the treatment of any Permitted Indications (the JCC). Tercica and Insmed each shall initially appoint two (2) representatives to
the JCC, and GNE may initially appoint up to two (2) representatives to the JCC. Following any exercise of its Opt-In rights, GNE shall appoint at least one (1), but no more than two (2), representatives to JCC. The JCC may change its size from
time to time by mutual consent of its members, provided that the JCC shall include at all times of an equal number of representatives of each of Tercica, Insmed, and where GNE so

elects, of GNE. Each Party may replace its JCC representatives at any time upon written notice to the other Party(ies). The JCC may invite non-members to
participate in the discussions and meetings of the JCC, provided that such participants shall have no voting authority at the JCC. The JCC will be chaired initially by Insmed. The chairperson shall be responsible for administering JCC meetings, but
shall have no additional powers or rights beyond those held by the other representatives on the JCC.

(b) Meetings. The JCC shall
meet at least twice per year after its formation pursuant to Section 6.3(a) unless the Parties mutually agree in writing to a different frequency. The JCC may meet in person, by videoconference, or by teleconference. The location of in-person
JCC meetings will be held at locations alternately selected by Tercica, Insmed and GNE. Meetings of the JCC shall be effective only if at least one representative of each Party is present or participating in such meeting. Each Party shall report to
the JCC on all material issues relating to the commercialization of Products promptly after such issues arise. Each Party will bear the expense of its respective JCC members participation in JCC meetings. The chairperson will be responsible
for preparing reasonably detailed written minutes of JCC meetings that reflect, without limitation, material decisions made at such meetings. Such meeting minutes will be sent to each member of the JCC for review and approval within ten
(10) business days after a meeting.

(c) Decision-Making. The JCC shall act by consensus. The representatives from each Party
will have, collectively, one (1) vote on behalf of that Party. If the JCC cannot reach consensus on any issue that comes before the JCC, then:

(i) prior to the date when, and if, an Opt-In Party exercises its Sole Promotion Rights with respect to a particular Opt-In Indication pursuant to Section 5.4, and other than with respect to Sales Tracking Methodology matters,
Insmed shall have the deciding vote for all issues to be determined by the JCC; and

(ii) following the date when an Opt-In Party
exercises its Sole Promotion Rights with respect to a particular Opt-In Indication pursuant to Section 5.4, such Opt-In Party shall have the deciding vote for all issues to be determined by the JCC with respect to the commercialization of a
Product for such Opt-In Indication.

It is expressly understood and agreed that the control of decision-making authority by a Party so as to resolve a
disagreement or deadlock at the JCC for any matter will not relieve such Party from any of its representations, warranties, or covenants in this Agreement, nor will it enable such Party to unilaterally modify or amend the terms of this Agreement.

6.4 General Committee Authority. Each Committee shall have solely the powers assigned to it in this Article 6 and elsewhere in this
Agreement. No Committee shall have any power to amend, modify, or waive compliance with this Agreement.

6.5 Discontinuation of
Participation on a Committee. Each Committee shall continue to exist until the first to occur of (a) the Parties mutually agreeing to disband the Committee, or (b) Tercica providing to Insmed written notice of its intention to disband
and no longer participate in such Committee. In any event, at any time Tercica and/or GNE may

terminate its participation on any Committee, on thirty (30) days written notice. Unless the Parties agree otherwise in writing at the time, upon
dissolution of a Committee, such Committees powers and duties shall automatically be assumed by Insmed; provided, however, the Opt-In Partys approval shall be required for any decisions made by Insmed after the dissolution of a
Committee, such approval not to be unreasonably withheld or delayed.

(ii) Insmed has commenced such development of such Product but the Opt-In right described in Section 4.2 has not yet been exercised (Off-Label Sales). In such event, the royalty owed to Tercica on such Off-Label Sales
will be paid pursuant to subsection (3) below. If, following commencement of payment of royalties for such Permitted Indication to Tercica pursuant to subsection (3) below, neither Tercica nor GNE exercises the Opt-In right described in
Section 4.2 for such Permitted Indication, then upon grant of Marketing Authorization for such Product in the treatment of such Permitted Indication in a given country, the royalty for sales of Product for such Permitted Indication in such
country shall be [ * ].

(3) Calculation of Royalties Due under Subsections (1) and (2) Above. For the purpose of this
subsection (3), Aggregated Named Patient and Off-Label Sales shall mean collectively, (A) the ALS Portion; (B) the annual Net Sales of all Products aggregated across all countries which result from Named Patient Basis
sales other than ALS pursuant to Section 3.1(b); and (C) the annual Net Sales of all Products aggregated across all countries which are Off-Label Sales. The Aggregated Named Patient and Off-Label Sales described in (B) and
(C) shall be referred to as the Non-ALS Portion. In calculating royalties due under this subsection (3), the following rules shall apply:

(a) Determining Royalties Due for the Non-ALS Portion: The royalties due for the Non-ALS Portion shall equal the Aggregated Royalty Amount less the ALS Credit.

(i) The Parties shall determine the Aggregated Royalty Amount by applying the applicable royalty rates set forth in Table A below to the
Annual Aggregated Named Patient and Off-Label Sales;

Table A for Calculating Aggregated Royalty Amount:

(ii) The Parties shall then determine the ALS Credit by applying the applicable royalty rates set
forth in Table B below to the ALS Portion:

(b) Example. By way of illustration, if, for a given year, the ALS Portion is [ * ], and
the Non-ALS Portion is [ * ], then the Aggregated Named Patient and Off-Label Sales shall be [ * ]. The royalties payable shall be calculated as follows:

(i) For the ALS Portion: As set forth in Section 7.1(a)(iii), the first [ * ] of the ALS Portion shall bear royalties at a rate of [ * ], resulting in a royalty obligation of [ * ]; and the next [ * ] of
the ALS Portion shall bear royalties at a rate of [ * ], resulting in a royalty obligation of [ * ]. The total royalty obligation for the ALS Portion shall be [ * ] and shall be paid directly to GNE

(ii) For the Non-ALS Portion: As set forth in Section 7.1(a)(iv), such royalty is equal to the Aggregated Royalty Amount minus the ALS
Credit, calculated as follows:

Aggregated Royalty Amount:



|                                                     |  |

Royalties Due for Non-ALS Portion: The royalty payments for Non-ALS Portion shall be: [ * ]
and shall be paid directly to Tercica.

(b) Royalty Obligations to GNE with Respect to Tercicas Opt-In Indication(s). In the
event GNE does not elect to exercise its Opt-In rights for a given Permitted Indication, but Tercica does so exercise its Opt-In rights for such Permitted Indication, for so long as Tercica has not exercised its Opt-Out right, Insmed or Tercica, as
the case may be and whichever is the Booking Party, shall pay to GNE the incremental rates set forth below, on annual Net Sales of all Products used in the treatment of such Permitted Indication, aggregated across all such Permitted Indications as
to which this Section 7.1(b) applies:



|                                                                     |  |

Such royalties owed GNE shall be deducted from Actual Sales in calculating Operating Profit (Loss).

(c) Royalties for Mass Sales. Notwithstanding any other provision in this Section 7.1, Insmed shall pay to Tercica a royalty at the rate
equal to [ * ] of its Net Sales of any mass sales of a Product to a buyer who is governmental agency, quasi governmental agency, institution, foundation or other organization or entity and pursuant to a bulk sales contract or other arrangement, but
excluding any sales of a Product pursuant to contract or purchase order to distributors in the normal course of business for any intended use.

---

(d) Royalty Report and Payment. All royalty amounts payable to Tercica (or GNE as applicable)
pursuant to this Section 7.1 shall be paid in Dollars within thirty (30) days after the end of each calendar quarter with respect to Net Sales in such calendar quarter. Each payment of royalties due to Tercica (or GNE as applicable) shall
be accompanied by a statement, on a country-by-country basis, of the amount of gross sales of Product for the applicable indication during the applicable calendar quarter, an itemized calculation of Net Sales in the Territory showing deductions
provided for in the definition of Net Sales during such calendar quarter, and a calculation of the amount of royalty payment due on such sales for such calendar quarter in accordance with Sections 7.1(a)(i), 7.1(a)(ii), 7.1(a)(iii), 7.1(a)(iv) and
7.1(b).

(e) Royalty Payment Term. All royalty obligations that apply to sales of Product for use in an indication in a Sale Country
pursuant to this Section 7.1 shall extend, on a Product-by-Product, Permitted Indication-by-Permitted Indication, and Sale Country-by-Sale Country basis, until the later of (a) the expiration of the last to expire Licensed Patents existing
in such Sale Country that would, but for the license grant in Section 3.1, be infringed by the use, sale, offer for sale, or importation of such Product for use in such Permitted Indication in such Sale Country and (b) the expiration of
the last to expire Licensed Patents existing in such Sale Country or other country, that would, but for the license grant in Section 3.1, be infringed by the actual method of manufacture or use of such Product (or a component thereof) as
practiced by Insmed in the manufacture of such Product in such Sale Country or such other country that is subsequently sold for use in such Permitted Indication in such Sale Country.

(f) Minimum Royalty. The Parties acknowledge that there may be dispute between the Parties with respect to which Net Sales are attributable to
which Permitted Indication, or the calculation of any royalties due thereunder, which may be ongoing as of the end of a given calendar quarter (the Sales Tracking Dispute). The Parties agree that Insmeds royalty payment
obligations under Section 7.1(a)(i) for sales of a Product to Existing Patients and under Section 7.1(c) for mass sales shall not be affected by any Sales Tracking Dispute, and shall be due and owing at the end of the relevant quarter in
accordance with Section 7.1(d) above regardless of any then existing Sales Tracking Dispute. With respect to Insmeds royalty payment obligations under Sections 7.1(a)(ii) through 7.1(a)(iv), or 7.1(b) or the payment of Operating Profit
(Loss), any such Sales Tracking Dispute shall only affect the payment of the portion of the royalties in dispute, and the remainder of the royalties (which shall at all times be at least [ * ] of all Net Sales for each Permitted Indication) shall
nevertheless be due and owing at the end of the relevant quarter in accordance with Section 7.1(d) above.

7.2 Sharing of Operating
Profit of Product for an Opt-In Indication.

(a) Profit Share. The Parties shall share the Operating Profit (Loss) for each
Opt-In Indication based on the applicable Percentage Interest for such Opt-In Indication.

(b) Quarterly Calculations. Each
Partys share of Operating Profit (Loss) will be determined on a calendar quarterly basis, using a weighted average based on forecasted Actual Sales (as defined in Exhibit A) for a Product for the Opt-In Indication for the then current
calendar year and actual Operating Profit (Loss) for the completed calendar quarter.

[  *  ] = CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED

AND EXCHANGE COMMISSION PURSUANT TO RULE 24B-2 OF THE SECURITIES EXCHANGE
ACT OF 1934, AS AMENDED.



---

(c) Quarterly Reconciliation. On a calendar quarterly basis after the end of each calendar
quarter, each Partys actual share of Operating Profit (Loss) will be calculated and reconciled as follows: the forecasted Actual Sales for a Product for such Opt-In Indication for the then current calendar year will be adjusted based on the
actual sales booked for the recently-completed calendar quarter and the forecasted Actual Sales for all remaining calendar quarters. Then, each Partys share of cumulative Operating Profit (Loss) for all of the completed calendar quarter(s) for
such calendar year will be determined using a weighted average based on such newly-calculated Actual Sales and the actual Operating Profit (Loss) for all such completed calendar quarter(s) for such calendar year. The payment to be made by one Party
to the other Party for such recently-completed calendar quarter shall reflect such reconciliation, so that each Party will receive its share of then-current cumulative Operating Profit (Loss).

(d) Reconciliation Payments. If the Opt-In Party does not exercise its Sole Promotion Option, then, as between the Parties, Insmed shall be the
Booking Party for such Product for the Opt-In Indication. If the Opt-In Party exercises its Sole Promotion Option, then such Opt-In Party shall be the Booking Party for such Product for the Opt-In Indication. In accordance with the timeline set
forth in Exhibit A, for as long as any Product is being commercialized for an Opt-In Indication, the Non-Booking Party shall submit to the Booking Party a statement setting forth any expenditures incurred in any of the elements of calculation
of the Operating Profit (Loss) by such Non-Booking Party for the sale of Product for the Opt-In Indication during such calendar quarter, together with the information detailing the basis for the calculation of such expenditures, in detail and by
category of expenditure. The Booking Party shall consolidate any such Operating Profit (Loss) expenditures reported by such Non-Booking Party with those obtained directly by the Booking Party. The Booking Party shall, in accordance with the time
periods set forth in Exhibit A, notify such Non-Booking Party whether a reconciliation payment is due from one Party to the other based on its calculation pursuant to Section 7.2(c) above, and if so, the amount of such reconciliation
payment, so that the Parties will share the Operating Profit (Loss) for such calendar quarter in the ratio set forth in Section 7.2(a). The Party required to pay such reconciliation payment shall submit such payment to the other Party within
the time period set forth in Exhibit A.

7.3 GNE License Fee. Upon receipt of invoice from Tercica, Insmed shall reimburse
Tercica for license payments made to GNE pursuant to Section G.1(a)(x) of Exhibit G to the GNE US License. For clarity, Insmed shall have no further obligation under this Section 7.3 upon Insmeds reimbursement of Tercica for the final
license payment made by Tercica to GNE pursuant to Section G.1(a)(x) of Exhibit G to the GNE US License, which final license payment is the last payment made to GNE by Tercica under such section of the GNE US License before the expiration of the
last to expire patent in the BP3 Patents (as that term is defined in Section 1.7 of the GNE US License) existing in the United States. For additional clarity, nothing in this Section 7.3 shall be construed to limit or amend Tercicas
obligation to pay GNE any license payments due pursuant to Section G.1(a)(x) of Exhibit G to the GNE US License.

7.4 Taxes. A Party
receiving a payment pursuant to this Article 7 shall pay any and all taxes levied on such payment. If applicable law requires that taxes be deducted and withheld from a payment made pursuant to this Article 7, the remitting Party shall
(i) deduct those taxes from the payment; (ii) pay the taxes to the proper taxing authority; and (iii) send evidence of the

obligation together with proof of payment to the other Party within sixty (60) days following that payment.

7.5 Blocked Currency. In each country where the local currency is blocked and cannot be removed from the country, royalties accrued in that
country shall be paid to the other Party in the country in local currency by deposit to a local bank designated by such Party, unless the Parties otherwise agree.

7.6 Foreign Exchange. The rate of exchange to be used in computing the amount of currency equivalent in Dollars owed to a Party under this Agreement shall be made at the period-end rate of exchange quoted on
the last business day of the applicable calendar quarter by Citibank in New York City.

7.7 Late Payments. If a Party does not
receive payment of any sum due to it on or before the due date, simple interest shall thereafter accrue on the sum due to such Party until the date of payment at the per annum rate of two percent (2%) over the then-current prime rate quoted by
Citibank in New York City or the maximum rate allowable by applicable law, whichever is greater. All payments made hereunder shall be made net of any withholding taxes.

7.8 Financial Records; Audits. Each Party will maintain complete and accurate records in sufficient detail to permit the other Parties to confirm the accuracy of the Development Costs incurred by such Party and
the calculation of royalty payments, Operating Profit (Loss), and other compensation payable under this Agreement. In addition, Insmed will maintain complete and accurate records of its Named Patient Basis sales under Sections 3.1(b) and (d) in
sufficient detail to permit GNE or Tercica to confirm the accuracy of such sales. Upon reasonable prior notice, such records shall be open during regular business hours for a period of three (3) years from the creation of individual records for
examination at the auditing Partys expense, and not more often than once each calendar year, by an independent certified public accountant selected by the auditing Party and reasonably acceptable to the audited Party for the sole purpose of
verifying for the auditing Party the accuracy of the financial reports furnished by the audited Party pursuant to this Agreement or of any payments made by the audited Party to the non-audited Party pursuant to this Agreement. Any such auditor shall
not disclose the audited Partys Confidential Information to the auditing Party, except to the extent such disclosure is necessary to verify the accuracy of the financial reports furnished by the audited Party or the amount of payments due by
the audited Party under this Agreement. Any amounts shown to be owed but unpaid shall be paid within thirty (30) days from the accountants report, plus interest (as set forth in Section 7.6) from the original due date. The auditing
Party shall bear the full cost of such audit unless such audit discloses an underpayment of the amount actually owed during the applicable calendar year of more than five percent (5%), in which case the audited Party shall bear the full cost of such
audit.

such prosecution efforts regarding such patents relating to a Product for the Opt-In Indication within the Insmed Patents, (ii) Insmed shall provide such Opt-In Party with a copy of material communications from any patent authority in the
Territory regarding such patents within the Insmed Patents, and shall provide drafts of any material filings or responses to be made to such patent authorities a reasonable amount of time in advance of submitting such filings or responses, and

sole control, an appropriate suit or other action against any person or entity engaged in such infringement of a patent within the Insmed Patents.

8.3 Infringement of Third Party Rights.

(a) Notice. If any Product manufactured, used or sold by either Party, its
Affiliates, licensees or sublicensees becomes the subject of a Third Partys claim or assertion of infringement of a patent granted by a jurisdiction within the Territory relating to the manufacture, use, sale, offer for sale or importation of
a Product, and if Tercica or GNE is the Opt-In Party for a Product for any Opt-In Indication implicated in such claim or assertion, then: (i) if the Opt-In Party first has notice of the claim or assertion, it shall promptly notify Insmed; and
(ii) if Insmed first has notice of the claim or assertion, it shall promptly notify such Opt-In Party. The Parties shall then promptly meet to consider the claim or assertion and the appropriate course of action.

Article 12 for another Partys uncured Material Breach, but instead elect to allow this Agreement to continue in effect, in which case, the breaching Party shall continue to be liable to the non-breaching Party(ies) for such Material Breach.
The non-breaching Party(ies) shall be entitled to pursue legal and equitable remedies arising from such Material Breach that are available to it or them (as applicable), regardless of whether such non-breaching Party(ies) terminates this Agreement

breaches its payment obligations to Tercica under Article 7.

(ii) Consequences of Termination by Tercica or GNE. If Tercica or GNE

any component contained in such Product;

(4) within five (5) business days after the effective date of such termination, in

(b) Additional Rights to Terminate for Insmeds Material Breach Where Such Material Breach is
with Respect to a Specific Permitted Indication that is an Opt-In Indication.

(i) Opt-In Partys Right to
Terminate. If Insmed commits a Material Breach with respect to a Permitted Indication that is an Opt-In Indication, then the Opt-In Party shall have the right, without the other, non-Opt-In Partys consent, to terminate this Agreement only
with respect to such Opt-In Indication, pursuant to Section 12.2 above. Notwithstanding the foregoing sentence, and as further described in Section 12.3(b)(iii), under certain circumstances, GNE shall also have the right to terminate this
Agreement with respect to an Opt-In Indication even if GNE is not the Opt-In Party for such Opt-In Indication.

(ii) Consequences of
Termination by an Opt-In Party. If an Opt-In Party terminates this Agreement with respect to a particular Opt-In Indication pursuant to Section 12.3(b)(i) above, then:

(1) the licenses granted to Insmed in Section 3.1 shall immediately terminate with respect to such Opt-In Indication;

(2) the Permanent Injunction and the UK Proceedings Settlement Agreement shall each remain in full force and effect;

(3) the Opt-In Party shall have the right to take over development of such Opt-In Indication in its entirety, at its own expense, in accordance
with the financial consequences as described in the remainder of this Section 12.3(b)(ii)(3). If the Opt-In Party elects to take over development of such Opt-In Indication in its entirety, then the Percentage Interest of Insmed in such Opt-In
Indication shall be reduced to a portion equal to the result of the following formula:



|       |  |                                                                                                                                                     |  |                                                                                            |  |

|       |  | 50% x (Total Development Costs incurred by Insmed and the Opt-In Party to obtain regulatory approval of such Product in the given country at issue) | 

The profit-sharing arrangement (as adjusted pursuant to the formula in this Section 12.3(b)(ii)(3)) shall
continue only until the payments so received by Insmed equal the Development Costs actually incurred by Insmed for the Product for such Opt-In Indication, after which the profit share arrangement for such Opt-In Indication shall terminate. For
illustration, if Insmed has actually funded $4 million of the total Development Costs prior to the date of the Material Breach, and the total Development Costs incurred by Insmed and such Opt-In Party to obtain regulatory approval of the Product in
a given country at issue is $20 million, then Insmeds newly calculated Percentage Interest after such termination shall be 50% x ($4 million/(50% x $20 million)) = 20%. The Opt-In Party shall share Operating Profit (Loss) with Insmed for such
Product for such Permitted Indication in such country on a 80:20 basis until Insmed receives a total of $4 million in proceeds from such Operating Profit (Loss) sharing, after which the profit share arrangement shall terminate. The principle of this
illustration shall also apply to Sections 12.3(b)(iii)(3), 12.4(b)(ii)(2)(b), and 12.5(b).

After the termination of the profit share arrangement for such Opt-In Indication pursuant to subsection (3) above,
the Opt-In Party shall pay to Insmed royalties on the Net Sales for such Opt-In Indication at a rate of [ * ], and such royalty payment obligation shall expire in a given Sale Country on a Sale Country-by-Sale Country basis, upon the later of
(A) the expiration of the last to expire Insmed Patents existing in such Sale Country that would be infringed by the use, sale, offer for sale, or importation of such Product for use in such Opt-In Indication in such Sale Country but for the
license grant in Section 3.2(b), and (B) the expiration of the last to expire Insmed Patents existing in such Sale Country or other country that covers the actual method of manufacture or use of the Product (or a component thereof) as
practiced by Insmed in the manufacture of the Product in such Sale Country or such other country that is subsequently sold for use in such Opt-In Indication in such Sale Country;

(4) the Opt-In Party (a) shall become, if not already, the Booking Party for such Opt-In Indication; and (b) shall have the final
decision making authority in the commercialization of such Product for such Opt-In Indication.

(iii) Right and Consequences of
Termination by GNE When It is Not the Opt-In Party for the Permitted Indication. Notwithstanding anything to the contrary in this Section 12.3(b), if Insmed commits a Material Breach with respect to an Opt-In Indication when Tercica is the
Opt-In Party for such Opt-In Indication, then GNE shall have the right to terminate this Agreement with respect to such Opt-In Indication only in the event that Insmeds Material Breach is an underpayment to GNE of the royalties under
Section 7.1(b). In the event of such termination:

(1) the licenses granted to Insmed in Section 3.1 shall immediately
terminate with respect to such Permitted Indication;

(2) the Permanent Injunction and the UK Proceedings Settlement Agreement
shall each remain in full force and effect;

(3) Tercica shall have the right to take over development of such Permitted Indication
in its entirety, at its own expense, in accordance with the financial consequences as described in remainder of this Section 12.3(b)(iii)(3). If Tercica elects to take over development of such Permitted Indication in entirety, then the
Percentage Interest of Insmed in such Permitted Indication shall be reduced to a portion equal to the result of the following formula:

The profit-sharing arrangement (as adjusted pursuant to the formula in this Section 12.3(b)(iii)(3)) shall
continue only until the payments so received by Insmed equal the Development Costs actually incurred by Insmed for a Product for such indication. The formula provided in this Section 12.3(b)(iii)(3) shall be interpreted based on the same
principle set forth in the illustration in Section 12.3(b)(ii)(3). Thereafter the profit share arrangement for such indication shall terminate and Tercica shall pay to Insmed royalties on the Net Sales for such

Opt-In Indication at a rate of [ * ], and such royalty payment obligation shall expire in a given Sale Country on a Sale Country-by-Sale Country basis, upon
the later of (A) the expiration of the last to expire Insmed Patents existing in such Sale Country that would be infringed by the use, sale, offer for sale, or importation of such Product for use in such Opt-In Indication in such Sale Country
but for the license grant in Section 3.2(b), and (B) the expiration of the last to expire Insmed Patents existing in such Sale Country or other country that covers the actual method of manufacture or use of such Product (or a component
thereof) as practiced by Insmed in the manufacture of such Product in such Sale Country or such other country that is subsequently sold for use in such Opt-In Indication in such Sale Country;

(4) Tercica (a) shall become, if not already, the Booking Party for such Opt-In Indication; (b) shall have the final decision making
authority in the commercialization of such Product for such Opt-In Indication; (c) shall make payments to GNE from the proceeds received from such future sales of a Product for such Opt-In Indication to cover both the royalties otherwise due
for such future sales and the unpaid royalties from sales booked prior to such termination; and (d) shall reserve all rights to seek recovery from Insmed for such royalty payments made to GNE by Tercica that account for the unpaid royalties
from sales booked prior to such termination and Insmed shall have the obligation to reimburse Tercica for all such payments, together with all costs and expenses incurred by Tercica in seeking such recovery from Insmed.

(c) Additional Rights to Terminate for Insmeds Material Breach Where Such Material Breach is with Respect to a Permitted Indication other than
an Opt-In Indication.

(i) Tercicas and GNEs Right to Terminate. If Insmed commits a Material Breach with respect
to a Permitted Indication other than an Opt-In Indication, then each of Tercica and GNE shall have the right to terminate this Agreement with respect to such Permitted Indication pursuant to Section 12.2 above, provided that, if at the time of
such proposed termination, the Opt-In rights of Tercica and GNE with respect to such Permitted Indication under Section 4.2 have not expired or lapsed, then the Party seeking to terminate this Agreement with respect to such Permitted Indication
shall obtain the written consent of the other non-breaching Party prior to such termination.

(ii) Consequences of Termination by
Tercica or GNE. If Tercica or GNE terminates this Agreement with respect to a particular Permitted Indication pursuant to Section 12.3(c)(i) above, then:

(1) such Permitted Indication shall thereafter be deemed, for all purposes under this Agreement to be a Non-Permitted Indication; and

(2) the remaining provisions set forth in this Agreement shall otherwise remain in full force and effect.

Agreement in its entirety pursuant to this Article 12 due to an uncured Material Breach with respect to more than one (1) Permitted Indications by a
breaching Party, such non-breaching Party may nonetheless elect not to terminate the Agreement in its entirety, in which event:

(a)
the Permanent Injunction shall remain in full force and effect; and

(b) the Agreement shall continue in full force and effect
except that to the extent the breaching Party is an Opt-In Party who has materially breached the Agreement by failing to co-fund the Development Costs of a Product for a particular Opt-In Indication, such Opt-In Party shall no longer have such right
to continue to co-fund such Development Costs, and the Percentage Interest of such Opt-In Party in such Opt-In Indication shall be reduced to a portion equal to the result of the following formula:



|       |  |                                                                                                                                                     |  |                                                                                            |  |

|       |  | 50% x (Total Development Costs incurred by the Opt-In Party and Insmed to obtain regulatory approval of such Product in the given country at issue) | 

The profit-sharing arrangement (as adjusted pursuant to the formula in this Section 12.5(b) shall continue
only until the payments so received by the Opt-In Party equal the Development Costs actually incurred by such breaching Opt-In Party for a Product for such Opt-In Indication (the formula provided in this Section 12.5(b) shall be interpreted
based on the same principle set forth in the illustration in Section 12.3(b)(ii)(3)), and thereafter the profit share arrangement for such Opt-In Indication shall terminate and the sales for such Opt-In Indication shall be subject to the
royalty payments set forth in Section 7.1(a)(ii) as if such Opt-In Indication was not an Opt-In Indication.

In addition, such election not to so
terminate the Agreement shall not constitute a waiver or release of, or otherwise be deemed to prejudice or adversely affect, any rights, remedies or claims, whether for damages or otherwise, that the non-breaching Party may have hereunder or that
may arise out of or in connection with such Material Breach by the breaching Party.

12.6 Other Remedies. Termination or expiration
of this Agreement for any reason shall not release any Party from any liability or obligation that already has accrued prior to such expiration or termination, nor affect the survival of any provision hereof to the extent it is expressly stated to
survive such termination. Termination or expiration of this Agreement for any reason shall not constitute a waiver or release of, or otherwise be deemed to prejudice or adversely affect, any rights, remedies or claims, whether for damages or
otherwise, that a Party may have hereunder or that may arise out of or in connection with such termination or expiration.

ARTICLE 13

DISPUTE RESOLUTION

Any dispute, controversy or claim arising out of or relating to this Agreement,
or the breach or termination thereof, shall be settled as follows:

13.1 Reference to Executives. Except as set forth in
Section 5.5(d) with respect to disputes involving sales tracking, in the event of a significant controversy, claim, or dispute arising out of or relating to this Agreement or any significant breach thereof (hereinafter collectively referred to
as a Dispute), the Parties agree that the Dispute shall be described in writing by one or all of the Parties and copies of the description(s) shall be sent to the General Counsel of Insmed, the General Counsel of Tercica, and the
General Counsel of GNE. These General Counsels (or their designees or equivalents who have decision-making authority) will then have thirty (30) days from receipt of such Dispute description to attempt in good faith to resolve the Dispute. In
the event that the Dispute is not resolved within this thirty (30) day time period, then any Party can proceed to arbitration of the Dispute, as described in Section 13.2, or to litigation, as described in Section 13.3.

13.2 Arbitration. Subject to Section 13.3, the Parties agree that any Dispute shall be resolved through negotiation. If a Dispute arises
between the Parties, and if said Dispute cannot be resolved pursuant to Section 13.1 (and such Dispute does not relate to a patent) then any such Dispute, including, without limitation, the interpretation, enforceability, performance, breach,
termination or validity hereof, including, without limitation, this arbitration clause, shall be solely and finally settled by arbitration in the manner specified in this Section 13.2. All arbitration proceedings shall be conducted in the San
Francisco Bay Area or such other location as is mutually agreed to by the Parties. The arbitration proceedings shall be conducted under the procedural rules of the American Arbitration Association or such other forum as is mutually agreed to by the
Parties. The Party requesting arbitration shall serve upon the other Party a written demand for arbitration stating the substance of the Dispute, and the contention of the Party requesting arbitration. Within sixty (60) days after the demand,
the Parties shall select three (3) arbitrators as follows: each Party shall designate one arbitrator, and those two arbitrators shall designate a third. The decision of the arbitrators shall be in writing setting forth the basis therefor. The
arbitrators shall have the authority to award such remedies as they believe are appropriate in the circumstances, including, but not limited to, compensatory damages, interest, tort damages (but not consequential and incidental damages or punitive
or similar damages) and specific performance and other equitable relief. The Parties shall abide by the award rendered in such arbitration proceeding, and such award may be entered, enforced and executed upon in the United States District Court for
the Northern District of California. The Parties shall divide equally the administrative charges, arbitrators fees and related expenses of arbitration, but each Party shall pay its own attorneys fees incurred in connection with such
arbitration; provided however, if the arbitrators specifically determine that one Party prevailed clearly and substantially over the other Party, then the arbitrators may require that the non-prevailing Party shall also pay the prevailing
Partys reasonable attorneys fees and expert witness costs and arbitration costs.

13.3 Patent Dispute Resolution. Any dispute, controversy or claim relating to the scope, validity,
enforceability or infringement of any Licensed Patents or Insmed Patents covering the manufacture, use or sale of any Product shall be submitted to a court of competent jurisdiction.

13.4 Governing Law. In the event that a Dispute is not resolved though discussion of the executives pursuant to Section 13.1, as provided
above, the laws of California shall apply to any arbitration or litigation under this Agreement (regardless of its or any other jurisdictions choice of law principles),provided that matters of intellectual property law shall be
determined in accordance with the national intellectual property laws relevant to the intellectual property in question. For any disputes, arbitrations or litigation under this Agreement, each Party hereby consents to personal jurisdiction and venue
in the United States District Court for the Northern District of California, and agrees to service of process issued or authorized by such Court.

13.5 Restraining Order. The dispute resolution procedures set forth herein shall not limit a court from granting a temporary restraining order or a preliminary injunction in order to preserve the status quo of the Parties
pending arbitration or to protect a Partys trademark or confidential or proprietary information. Further, the arbitrator shall have power to enter such orders by way of interim award, and such orders shall be enforceable in court.

ARTICLE 14

14.4 Assignment. None of the Parties may assign or transfer this Agreement or any rights or
obligations hereunder without the prior written consent of the other Parties, except that a Party may make such an assignment without the other Parties consent to Affiliates or to a successor to substantially all of the business of such Party
in the field to which this Agreement relates, whether in a merger, sale of stock, sale of assets or other transaction. Any permitted successor or assignee of rights and/or obligations hereunder shall, in a writing to each of the other Parties,
expressly assume performance of such rights and/or obligations. Any permitted assignment shall be binding on the successors of the assigning Party. Any assignment or attempted assignment by any Party in violation of the terms of this
Section 14.4 shall be null, void and of no legal effect. Notwithstanding the aforesaid, to the extent such assignment of rights is permitted in any section of this Agreement other than this Section 14.4, Ipsen shall be considered a
permitted assignee of Tercica.

14.5 Performance by Affiliates. Each Party may discharge any obligations and exercise any right
hereunder through any of its Affiliates. Each Party hereby guarantees the performance by its Affiliates of such Partys obligations under this Agreement, and shall cause its Affiliates to comply with the provisions of this Agreement in
connection with such performance. Any breach by a Partys Affiliate of any of such Partys obligations under this Agreement shall be deemed a breach by such Party, and the other Party may proceed directly against such Party without any
obligation to first proceed against such Partys Affiliate.

14.6 Further Actions. Each Party agrees to execute, acknowledge
and deliver such further instruments, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.

14.7 Severability. If any one or more of the provisions of this Agreement is held to be invalid or unenforceable by any court of competent jurisdiction from which no appeal can be or is taken, the provision
shall be considered severed from this Agreement and shall not serve to invalidate any remaining provisions hereof. The Parties shall make a good faith effort to replace any invalid or unenforceable provision with a valid and enforceable one such
that the objectives contemplated by the Parties when entering this Agreement may be realized.

14.8 No Waiver. Any delay in
enforcing a Partys rights under this Agreement or any waiver as to a particular default or other matter shall not constitute a waiver of such Partys rights to the future enforcement of its rights under this Agreement, except with respect
to an express written and signed waiver relating to a particular matter for a particular period of time.

14.9 Independent
Contractors. Each Party shall act solely as an independent contractor, and nothing in this Agreement shall be construed to give any Party the power or authority to act for, bind, or commit any other Party in any way. Nothing herein shall be
construed to create the relationship of partners, principal and agent, or joint-venture partners between the Parties.

14.10
Counterparts. This Agreement may be executed in one (1) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

EXHIBIT A

FINANCIAL APPENDIX

This Exhibit A to the Agreement sets forth
financial planning, accounting policies and procedures to be followed in determining Operating Profit (Loss) and related sharing of revenue and expenses for a Product for an Opt-In Indication and for calculating Net Sales for purposes of
Section 7.1. Except as required for calculating Net Sales for purposes of Section 7.1, the terms and conditions set forth in this Exhibit A shall apply following the exercise of a Partys Opt-In rights until the exercise by the Opt-In
Party of the Opt-In Partys Opt-Out rights, if any, to the sales of a Product for the Opt-In Indication in the Territory.

The contents of this
Exhibit A are hereby incorporated into the Agreement and are governed by the terms and conditions of the Agreement, including the confidentiality provisions set forth therein.

A.1 Principles of Reporting.

The presentation of budgets and results of operations of Insmed and the Opt-In Party
in the Territory will be based on each Partys respective financial information presented separately and on a consolidated basis using the following schema (financial terms are defined further below):

Gross Sales

less Sales Returns &
Allowances

= Actual Sales

less Cost of Sales (which includes FBMC)

less Distribution Costs (which includes Allocable Overhead)

less G&A Costs

less Other Operating
Income/Expense

less Development Costs (which includes Allocable Overhead)

less Selling and Marketing Costs (which includes Allocable Overhead)

= Operating Profit (Loss)

The types of costs in this schema are to be grouped together as follows:



|                               |  |                    |  |                           
|------------------------------ |  | ------------------ |  | --------------------------
|DIRECT COSTS                   |  | NON-DIRECT COSTS   |  | TERMS FOR CALCULATING     
|Cost of Sales                  |  | Allocable Overhead |  | Operating Profit (Loss)   
|Development Costs              |  | G&A Costs          |  | Gross Sales

|Other Operating Income/Expense |  |                    |  |                           
|Selling and Marketing Costs    |  |                    |  |

If necessary, a Party will make the appropriate adjustments to the financial information it supplies under the Agreement
to conform to the above format of reporting results of operations.

Accounting and Cost Categories. Definitions of the various categories of
revenues, costs and expenses included in Operating Profit (Loss) shall be interpreted in accordance with GAAP. Any costs included in the calculation under one cost category may not be included in the calculation of another cost category. Where the
terms of this Financial Appendix would permit inclusion of a cost within more than one cost category, that cost will be allocated to a single cost category consistent with GAAP and the other provisions of this Agreement. Any cost included in this
calculation shall only include costs directly or indirectly (to the extent allowed and consistent with the definitions for this Financial Appendix) allocable to a Product for the Opt-In Indication in accordance with GAAP.

References to Collaboration.References in this Financial Appendix to the Collaboration are references to those activities related
to a Product that would form the basis for Operating Profit (Loss) under this Agreement. The Parties may consolidate accounting of operations related to Product for the specific Opt-In Indication, and the activities subject to that consolidated
accounting also will be referred to as the Collaboration. Where the same Parties are Collaborating on more than one Opt-In Indication, the accounting of operations related to a Product for all such Opt-In Indications may be consolidated.
However, the Collaboration is not a legal entity for financial accounting, income tax reporting or any other purposes

A.2 Frequency of
Reporting.

The fiscal year for the Collaboration will be a calendar year.

Each of Insmed and the Opt-In Party is responsible for providing the other Party reports as set forth in the table below, for activities for which it is
responsible and costs it incurred and revenue obtained that forms a component of Operating Profit (Loss) for Product for the Opt-In Indication(s).

Reporting will be at the times set forth in the following Report Table, with submissions due on the date indicated or the next business day if such date is a weekend or U.S. holiday:

Operating Profit (Loss) for the Collaboration. Without limiting the Parties reporting obligations as set forth in the Report Table above, on a calendar
quarterly basis, the Party that is not responsible for booking sales (the Non-Booking Party) in accordance with Section 7.2(d) will supply the Booking Party with a statement setting forth that quarters Operating Profit (Loss)
obtained by the Non-Booking Party for the applicable Product for the Opt-In Indication, including the basis for calculation of such amounts. The Booking Party shall consolidate any Operating Profit (Loss) reported by the Non-Booking Party with those
obtained directly by the Booking Party. Each such report shall be provided as early as possible, on the schedule in the chart above.

Each Party will make
available a financial representative to coordinate regarding financial aspects of planning, reporting and information sharing, at the request of the other Party. Upon the reasonable request of either Party, the other Party shall answer any question
and address any comment from the other Party pertaining to such financial planning and reporting.

A.3 Budgets.

The Booking Party, through the JDC, will prepare a consolidated budget for Operating Profit (Loss) for the Collaboration on an annual basis; the
Non-Booking Party, through the JDC, shall provide input for that budget regarding its sales force activities.

Budgets are provided for information and
planning purposes, including establishing the initial profit share ratio for the forthcoming calendar year; final sharing of Operating Profit (Loss) on a calendar year basis are based on actual amounts. The Party that is the Non-Booking Party shall
not be required to fund an amount which is more than half of 110% of the budgeted amount for such expenditure without its prior written consent to such variance from budget.

RECITALS

Whereas, Plaintiff Tercica, Inc. is the exclusive licensee of U.S. Patent No. 6,331,414 entitled Preparation of Human IGF via Recombinant DNA Technology, which issued to Plaintiff Genentech,
Inc. as assignee of the inventors on December 18, 2001;

Whereas, Plaintiff Tercica, Inc. is the exclusive licensee of U.S.
Patent No. 5,187,151 entitled Use of Binding Protein with IGF-1 as an Anabolic Growth Promoting Agent, which issued to Plaintiff Genentech, Inc. as assignee of the inventors on February 16, 1993;

Whereas, Plaintiff Tercica, Inc. is the exclusive licensee of U.S. Patent No. 5,258,287 entitled DNA Encoding and Methods of Production

Whereas, on December 23, 2004, Plaintiffs Genentech, Inc. (GNE) and Tercica, Inc. (Tercica) filed this action against Insmed Incorporated
Genentech Inc., et al. v. Insmed Incorporated, et al., United States District Court for the Northern District of California, Case No. 04-CV-05429-CW (EMC) (the Lawsuit). By operation of the Second Amended Complaint, Defendant
Celtrix Pharmaceuticals, Inc. was added as a named defendant in the lawsuit. By operation of the Third Amended Complaint, Defendant Insmed Therapeutic Proteins was added as a named defendant to the Lawsuit. Plaintiffs alleged that Defendants
making, using, selling, offering to sell, import or export of the product known as IPLEX, infringed or will infringe under 35 U.S.C. § 271(a)  (c) and (g) certain asserted claims of United States Patent Nos. 5,187,151 (the
151 Patent), 5,258,287 (the 287 Patent) and 6,331,414 (the 414 Patent) (collectively, the Asserted Patents).

Whereas, Defendants denied such allegations and further alleged, among other defenses, that the asserted claims of the Asserted Patents were
invalid under various theories, including those arising under 35 U.S.C. §§ 102, 103, 112 and 135. Defendants further asserted that the 151 Patent was unenforceable for alleged inequitable conduct.

Whereas, the parties had a full and fair opportunity to litigate the case, including full fact and
expert discovery, and motion process, including claim construction, motions for summary judgment and other pretrial motions as reflected in the docket sheet.

Whereas, the Court adjudicated as a matter of law on June 30, 2006 that Defendants method of making the rhIGF-I component of IPLEX literally infringed Claims 1 and 9 of the 414 Patent
(Docket No. 510), and Defendants subsequently stipulated, subject to an appeal of the Courts claim construction, that their method also literally infringed Claims 2, 3, 4 and 10 of the 414 Patent.

Whereas, a jury trial commenced on November 6, 2006, that resulted in the Verdict Form (Docket No. 1006), filed December 6, 2006.
The Jury found that Defendants Insmed and Insmed Therapeutic Proteins (Insmed) induced infringement of Claims 1, 4 and 5 of the 151 Patent, contributorily infringed Claims 1, 4 and 5 of the 151 Patent, and literally infringed
Claims 1, 6-8 and 17 of the 287 Patent through the manufacture, distribution, sale, and/or offering to sell IPLEX in the United States as approved by the Food and Drug Administration. The Jury further found that Insmed had not proven
that Claims 1-4, 9-10 of the 414 Patent were invalid under the enablement or written description requirement. The Jury further found that Insmeds infringement of the 151 Patent was willful, and awarded damages to Tercica and GNE of
$7.5 million plus the royalty rates assessed in the Verdict Form on sales of IPLEX through December 6, 2006 (the Awarded Damages).

Whereas, following the verdict, Plaintiffs and Defendants made various post-trial motions, including Plaintiffs motion for a permanent injunction.

Whereas, Plaintiffs and Defendants (the Parties) have entered into a Settlement, License and Development Agreement (Settlement
Agreement), which is incorporated herein by reference, have withdrawn all pending motions, and have agreed to entry of this Consent Judgment and Permanent Injunction, subject to the Courts approval.

February 20, 2007

Dear ,

Today, Insmed, Tercica and Genentech concluded a Settlement, Development and Licensing Agreement which lays out the future development and commercialization of IPLEX. As part of the agreement, the companies settled
the outstanding patent infringement suit filed with the Federal Court of the Northern District of California pertaining to IPLEX. As a consequence of the courts finding of Tercicas patents having been infringed, Insmed will no longer be
able to provide IPLEX commercially to patients with severe primary IGF-1 deficiency and other short stature indications. It has been agreed that all patients will be transitioned off IPLEX as soon as the patients current supply of IPLEX is
exhausted.

Insmed and Tercica are fully committed to assisting you during this transition period. For children currently treated with IPLEX whom you
consider suitable for INCRELEX therapy, Tercica will supply INCRELEX free of charge while working with your office to secure reimbursement.

Tercicas
pediatric endocrinologists, Dr. George Bright and Dr. Sandra Blethen, would be pleased to discuss this transition and any medical questions you may have. You can reach them at (650) 624-4900 or 1-866-TERCICA.

Best regards,



|                                                                                                      |  |

Litigation Settlement Reached between Tercica, Genentech and Insmed

Companies Partner through License and Development Agreement

Brisbane, California and Richmond, Virginia. 
March 6, 2007  Tercica, Inc., (Nasdaq: TRCA) and Insmed Incorporated (Nasdaq: INSM) today announced that Tercica, Insmed and Genentech, Inc. (NYSE: DNA) have entered a Settlement, License and Development Agreement that resolves all
outstanding litigation between the companies, including the patent infringement suits brought by Tercica and Genentech against Insmed in the United States (N.D. Cal.) and United Kingdom, and the unfair business practices suit (E.D. Virginia). The
key elements of this settlement are:



| |  |  | Insmed will no longer provide IPLEX to patients with severe Primary IGF-1 Deficiency and other short stature indications and will withdraw its IPLEX marketing
authorization application for severe Primary IGF-1 Deficiency in the European Union
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Through licensing and development rights granted by Tercica and Genentech, Insmed will have freedom to operate regarding the manufacture, development and
commercialization of IPLEX for certain non short stature indications including severe insulin resistance, myotonic muscular dystrophy and HIV associated adipose redistribution syndrome (HARS), subject to opt-in rights and royalty provisions for
Tercica and Genentech
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Tercica and Genentech have waived the damages award by the jury in the U.S. patent infringement litigation.
| | - |  | -----------------------------------------------------------------------------------------------------------

In a joint statement, Dr. John A. Scarlett, Tercicas President and Chief Executive Officer, and Dr. Geoffrey Allan, Insmeds President,
Chief Executive Officer and Chairman of the Board of Directors stated, We are very pleased with our new licensing and development relationship. It allows Tercica to focus its efforts in the short stature market and allows Insmed, in
cooperation with Tercica and

Genentech, to focus its IPLEX development efforts in valuable non-short stature indications.

U.S./Canada IPLEX Sales for Tercica/Genentech Indications

As a
consequence of the courts finding that Tercicas patents were infringed, Insmed will no longer be able to provide IPLEX in the U.S. for severe Primary IGF-1 Deficiency and the following indications: Primary IGF-1 Deficiency, Noonans
Syndrome, Laron Syndrome, Growth Hormone Deficiency, and all other short stature indications; and Adult Growth Hormone Deficiency. These indications are collectively referred to as the TRCA/Genentech Indications. Insmed and Tercica will
work closely together with pediatric endocrinologists to identify therapeutic alternatives for children currently receiving IPLEX, and where appropriate, to transition patients to Increlex.

IPLEX Worldwide License and Development Agreement

The parties will
form a joint development (and subsequently, a joint commercialization) committee to guide the development and commercialization of IPLEX in non-Tercica/Genentech Indications. Tercica (along with Ipsen, for Ipsens Increlex territory) and
Genentech will have the right to opt into Insmeds development and commercialization of each non-Tercica/Genentech Indication up to 90 days after Insmed provides Phase III-enabling clinical data. Tercica will have the first right to
opt into orphan indications, and Genentech will have the first right to opt into non-orphan indications. If Tercica does not opt into an orphan indication, Genentech will have the right to opt-in. Similarly, if Genentech does not opt into a
non-orphan indication, Tercica will have the right to opt-in. In the case of an opt-in, Insmed will retain development control prior to approval, and Tercica or Genentech would gain commercial control after approval.

If the opt-in is exercised by Tercica, Insmed would be reimbursed 50% of its incurred development costs for the indication and further development costs would be shared
50:50. Upon subsequent commercialization, Insmed and Tercica will split

profits 50:50 after accounting for relevant expenses including sales-based tiered royalties of 6%-15% to Genentech.

If the opt-in is exercised by Genentech, Insmed would be reimbursed 50% of its incurred development costs for the indication. Subsequent development costs and profits
will be split 50:50, but no royalty will be owed to Tercica.

If neither Tercica nor Genentech opts in, Insmed will pay a 4% royalty on all commercial
sales of the approved drug to Genentech.

Worldwide pre-Approval IPLEX Sales

Outside the U.S. and Canada, Insmed will be permitted to continue to provide IPLEX to physicians through its Expanded Access Program for non Tercica/Genentech indications (excluding severe insulin resistance) and ALS
in Italy. Any cost reimbursement obtained from this program would be subject to a tiered royalty of 4% to 15% shared between Tercica, Genentech and Ipsen.

The Settlement, License and Development Agreement is in effect until the later of 2018 or the expiration of any subsequent Tercica/Genentech issued patents that cover IPLEX or its indications.
