The Lender agrees that unless an Event of Default shall have occurred and be continuing and the Lender shall have given the notice referred to in clause (b), such Grantor will have the exclusive voting power

with respect to any Investment Property constituting Collateral and the Lender will, upon the written request of such Grantor, promptly deliver such proxies and other documents, if any, as shall be reasonably requested by such Grantor which are necessary to allow such Grantor to exercise that voting power; provided that no vote shall be cast, or consent, waiver, or ratification given, or action taken by such Grantor that would impair any such Collateral or be inconsistent with or violate any provision of any Loan Document.

(c) Following the delivery of notice pursuant to clause (b)(ii), and so long as an Event of Default shall have occurred and be continuing, the Lender shall have the right to apply any amount in the Collateral Account to the payment of any Obligations which are then due and payable in accordance with Section 4.4(b) of the Credit Agreement.

(b) such Grantor shall promptly (but no less often than quarterly) notify the Lender if it knows, or has reason to know, that any application or registration relating to any material item of the Intellectual Property Collateral (excluding non-exclusive licenses of Intellectual Property) may, in the Grantor’s reasonable commercial judgment, become abandoned or dedicated to the public or placed in the public domain or invalid or unenforceable, or of any adverse determination or development (including the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, the United States Copyright Office or any foreign counterpart thereof or any court) regarding such Grantor’s ownership of or the validity or enforceability of any material Intellectual Property Collateral, or its right to register the same or to keep and maintain and enforce the same; and

SECTION 4.6. As to Letter-of-Credit Rights.

(a) Each Grantor, by granting a security interest in its Letter-of-Credit Rights to the Lender, intends to (and hereby does) collaterally assign to the Lender its rights (including its contingent rights ) to the Proceeds of all Letter-of-Credit Rights of which it is or hereafter becomes a beneficiary or assignee.

(b) Upon the occurrence of an Event of Default, such Grantor will, promptly upon request by the Lender, (i) notify (and such Grantor hereby authorizes the Lender to notify) the issuer and each nominated person with respect to each of the Letters of Credit that the Proceeds thereof have been assigned to the Lender hereunder and any payments due or to become due in respect thereof are to be made directly to the Lender and (ii) arrange for the Lender to become the transferee beneficiary of such Letter of Credit.

SECTION 4.8. Electronic Chattel Paper and Transferable Records. If any Grantor at any time holds or acquires an interest in any electronic chattel paper or any “transferable record,” as that term is defined in Section 201 of the U.S. Federal Electronic Signatures in Global and National Commerce Act, or in Section 16 of the U.S. Uniform Electronic Transactions Act as in effect in any relevant jurisdiction, with a value in excess of $100,000, such Grantor shall promptly notify the Lender thereof and, at the request of the Lender, shall take such action as the Lender may reasonably request to vest in the Lender control under Section 9-105 of the UCC of such electronic chattel paper or control under Section 201 of the Federal Electronic Signatures in Global and National Commerce Act or, as the case may be, Section 16 of the Uniform Electronic Transactions Act, as so in effect in such jurisdiction, of such transferable record. The Lender agrees with such Grantor that the Lender will arrange, pursuant to procedures satisfactory to the Lender and so long as such procedures will not result in the Lender’s loss of control, for the Grantor to make alterations to the electronic chattel paper or transferable record permitted under Section 9-105 of the UCC or, as the case may be, Section 201 of the U.S. Federal Electronic Signatures in Global and National Commerce Act or Section 16 of the U.S. Uniform Electronic Transactions Act for a party in control to allow without loss of control, unless an Event of Default has occurred and is continuing or would occur after taking into account any action by such Grantor with respect to such electronic chattel paper or transferable record.

SECTION 4.9. Further Assurances, etc. Each Grantor agrees that, from time to time at its own expense, it will, subject to the terms of this Agreement, promptly execute and deliver all further instruments and documents, and take all further action, that may be necessary or that the Lender may reasonably request, in order to perfect, preserve and protect any security interest granted or purported to be granted hereby or to enable the Lender to exercise and enforce its rights and remedies hereunder with respect to any Collateral.

(c) at all times keep pledged to the Lender pursuant hereto, on a first-priority, perfected basis, at the request of the Lender, all Investment Property constituting Collateral, all dividends and Distributions with respect thereto, and all interest and principal with respect to Promissory Notes, and all Proceeds and rights from time to time received by or distributable to such Grantor in respect of any of the foregoing Collateral;

(e) furnish to the Lender, from time to time at the Lender’s reasonable request, statements and schedules further identifying and describing the Collateral and such other reports in connection with the Collateral all in reasonable detail; and

(f) do all things reasonably requested by the Lender in accordance with this Security Agreement in order to enable the Lender to have and maintain control over the Collateral consisting of Investment Property, Deposit Accounts, Letter-of-Credit-Rights and Electronic Chattel Paper.

Each Grantor agrees that a carbon, photographic or other reproduction of this Security Agreement or any UCC financing statement covering the Collateral or any part thereof shall be sufficient as a UCC financing statement where permitted by law. Each Grantor hereby authorizes the Lender to file financing statements describing as the collateral covered thereby “all of the debtor’s personal property or assets, whether now owned or hereafter acquired” or

words to that effect, notwithstanding that such wording may be broader in scope than the Collateral described in this Security Agreement.

ARTICLE V

SECTION 5.1. Lender Appointed Attorney-in-Fact. Each Grantor hereby irrevocably appoints the Lender as its attorney-in-fact, with full authority in the place and stead of such Grantor and in the name of such Grantor or otherwise, from time to time in the Lender’s discretion, following the occurrence and during the continuance of an Event of Default, to take any action and to execute any instrument which the Lender may deem necessary or advisable to accomplish the purposes of this Security Agreement, including:

(a) to ask, demand, collect, sue for, recover, compromise, receive and give acquittance and receipts for moneys due and to become due under or in respect of any of the Collateral;

(b) to receive, endorse, and collect any drafts or other Instruments, Documents and Chattel Paper, in connection with clause (a) above;

(c) to file any claims or take any action or institute any proceedings which the Lender may deem necessary or desirable for the collection of any of the Collateral or otherwise to enforce the rights of the Lender with respect to any of the Collateral; and

(d) to perform the affirmative obligations of such Grantor hereunder.

Each Grantor hereby acknowledges, consents and agrees that the power of attorney granted pursuant to this Section is irrevocable and coupled with an interest.

SECTION 5.2. Lender May Perform. If any Grantor fails to perform any agreement contained herein, upon 5 days after the earlier to occur of (i) notice thereof given to any such Grantor by the Lender or (ii) the date on which such Grantor has knowledge of such failure, the Lender may itself perform, or cause performance of, such agreement, that the Lender deems necessary for the maintenance, preservation or protection of any of the Collateral or of its security interest therein to the extent provided for herein, and the expenses of the Lender incurred in connection therewith shall be payable by such Grantor pursuant to Section 10.3 of the Credit Agreement.

SECTION 5.3. Lender Has No Duty. The powers conferred on the Lender hereunder are solely to protect its interest in the Collateral and shall not impose any duty on it to exercise any such powers. Except for reasonable care of any Collateral in its possession and the accounting for moneys actually received by it hereunder, the Lender shall have no duty as to any Collateral or responsibility for

(a) ascertaining or taking action with respect to calls, conversions, exchanges, maturities, tenders or other matters relative to any Investment Property, whether or not the Lender has or is deemed to have knowledge of such matters, or

(b) taking any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral.

SECTION 5.4. Reasonable Care. The Lender is required to exercise reasonable care in the custody and preservation of any of the Collateral in its possession; provided that the Lender shall be deemed to have exercised reasonable care in the custody and preservation of any of the Collateral, if it takes such action for that purpose as each Grantor reasonably requests in writing at times other than upon the occurrence and during the continuance of any Event of Default, but failure of the Lender to comply with any such request at any time shall not in itself be deemed a failure to exercise reasonable care.

SECTION 5.5. Lender as Agent for Other Secured Parties. The Lender hereby agrees to act as agent of the other parties to which any Grantor may owe any Obligations for all purposes hereunder and under the other Loan Documents pursuant to which any Grantor grants a Lien or other right in any Collateral to secure the Obligations, for purposes of acquiring, holding and enforcing any and all Liens on any Collateral granted by any Grantor to secure any of the Obligations. The Lender may appoint any co-agents, sub-agents or attorneys-in-fact in connection with the foregoing.

ARTICLE VI
REMEDIES

SECTION 6.1. Certain Remedies. If any Event of Default shall have occurred and be continuing:

(a) The Lender may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of the Lender on default under the UCC (whether or not the UCC applies to the affected Collateral) and also may

(i) take possession of any Collateral not already in its possession without demand and without legal process;

(ii) require each Grantor to, and each Grantor hereby agrees that it will, at its expense and upon request of the Lender forthwith, assemble all or part of the Collateral as directed by the Lender and make it available to the Lender at a place to be designated by the Lender that is reasonably convenient to both parties,

(iii) enter onto the property where any Collateral is located and take possession thereof without demand and without legal process; and

(iv) without notice except as specified below, lease, license, sell or otherwise dispose of the Collateral or any part thereof in one or more parcels at any public or private sale, at any of the Lender’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Lender may deem commercially reasonable. Each Grantor agrees that, to the extent notice of sale shall be required by law, at least ten (10) days’ prior notice to such Grantor of the

time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Lender shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Lender may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

(b) All cash Proceeds received by the Lender in respect of any sale of, collection from, or other realization upon, all or any part of the Collateral shall be applied by the Lender against all or any part of the Obligations as set forth in Section 4.4(b) of the Credit Agreement.

(i) transfer all or any part of the Collateral into the name of the Lender or its nominee, with or without disclosing that such Collateral is subject to the Lien hereunder,

(ii) notify the parties obligated on any of the Collateral to make payment to the Lender of any amount due or to become due thereunder,

(iii) withdraw, or cause or direct the withdrawal, of all funds with respect to the Collateral Account;

(iv) enforce collection of any of the Collateral by suit or otherwise, and surrender, release or exchange all or any part thereof, or compromise or extend or renew for any period (whether or not longer than the original period) any obligations of any nature of any party with respect thereto,

(v) endorse any checks, drafts, or other writings in any Grantor’s name to allow collection of the Collateral,

(vi) take control of any Proceeds of the Collateral, and

(vii) execute (in the name, place and stead of any Grantor) endorsements, assignments, stock powers and other instruments of conveyance or transfer with respect to all or any of the Collateral.

SECTION 6.2. Securities Laws. If the Lender shall determine to exercise its right to sell all or any of the Collateral that are Capital Securities pursuant to Section 6.1(a)(iv), each Grantor acknowledges that the Lender may be unable to effect a public sale or other disposition of the Capital Securities by reason of certain prohibitions contained in the Securities Act of 1933, as from time to time amended (the “Securities Act”), federal banking laws, and other applicable laws, but may be compelled to resort to one or more private sales thereof to a restricted group of purchasers. Each Grantor agrees that any such private sale may be at prices and other terms less favorable to the seller than if sold at public sales and that such private sales shall not solely by reason thereof be deemed not to have been made in a commercially reasonable manner. The Lender shall be under no obligation to delay a sale of any of the Capital Securities for the period

of time necessary to permit the issuer of such securities to register such securities for public sale under the Securities Act, or such other federal banking or other applicable laws, even if the issuer would agree to do so. Subject to the foregoing, the Lender agrees that any sale of the Capital Securities shall be made in a commercially reasonable manner, and each Grantor agrees to use its reasonable best efforts to cause the issuer or issuers of the Capital Securities contemplated to be sold, to execute and deliver, all at the Grantors’ expense, all such instruments and documents, and to do or cause to be done all such other acts and things as may be necessary or, in the reasonable opinion of the Lender, advisable to exempt such Capital Securities from registration under the provisions of the Securities Act, and to make all amendments to such instruments and documents which, in the opinion of the Lender, are necessary or advisable, all in conformity with the requirements of the Securities Act and the rules and regulations of the Securities and Exchange Commission applicable thereto. If the Lender shall determine to exercise its right to sell all or any of the Collateral that are Capital Securities pursuant to Section 6.1(a)(iv), each Grantor further agrees to use its reasonable best efforts (a) to cause such issuer or issuers to exempt or comply with the provisions of the securities or “Blue Sky” laws of any jurisdiction which the Lender designates and obtain all necessary governmental approvals for the sale of the Capital Securities, as requested by the Lender; (b) if required, to cause such issuer or issuers to make available to its security holders, as soon as practicable, an earnings statement (which need not be audited) which will satisfy the provisions of Section 11(a) of the Securities Act; and (c) to do or cause to be done all such other acts and things as may be necessary to make such sale of the Collateral or any part thereof valid and binding and in compliance with applicable law.

SECTION 6.3. Compliance with Restrictions. Each Grantor agrees that in any sale of any of the Collateral whenever an Event of Default shall have occurred and be continuing, the Lender is hereby authorized to comply with any limitation or restriction in connection with such sale as it may be advised by counsel is necessary in order to avoid any violation of applicable law (including compliance with such procedures as may restrict the number of prospective bidders and purchasers, require that such prospective bidders and purchasers have certain qualifications, and restrict such prospective bidders and purchasers to Persons who will represent and agree that they are purchasing for their own account for investment and not with a view to the distribution or resale of such Collateral), or in order to obtain any required approval of the sale or of the purchaser by any Governmental Authority or official, and such Grantor further agrees that such compliance shall not result in such sale being considered or deemed not to have been made in a commercially reasonable manner, nor shall the Lender be liable nor accountable to such Grantor for any discount allowed by the reason of the fact that such Collateral is sold in compliance with any such limitation or restriction.

SECTION 6.4. Protection of Collateral. The Lender may from time to time, at its option, perform any act which any Grantor fails to perform after being requested in writing so to perform (it being understood that no such request need be given after the occurrence and during the continuance of an Event of Default) and the Lender may from time to time take any other action which the Lender deems necessary for the maintenance, preservation or protection of any of the Collateral or of its security interest therein.

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Grantor agrees, for the benefit of the Lender, as follows:

This SUPPLEMENT, dated as of ___, _____ (this “Supplement”), is to the Pledge and Security Agreement, dated as of August 8, 2017 (as amended, supplemented, amended and restated or otherwise modified from time to time, the “Security Agreement”), among the Grantors (such term, and other terms used in this Supplement, to have the meanings set forth in Article I of the Security Agreement) from time to time party thereto, in favor of ORBIMED ROYALTY OPPORTUNITIES II, LP, a Delaware Limited Partnership (together with its Affiliates, successors, transferees and assignees, the “Lender”).

W I T N E S S E T H :

WHEREAS, pursuant to the provisions of Section 7.6 of the Security Agreement, each of the undersigned is becoming a Grantor under the Security Agreement; and

WHEREAS, each of the undersigned desires to become a “Grantor” under the Security Agreement in order to induce the Lender to continue to extend Loans under the Credit Agreement;

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, each of the undersigned agrees, for the benefit of the Lender, as follows.

SECTION 1. Party to Security Agreement, etc. In accordance with the terms of the Security Agreement, by its signature below, each of the undersigned hereby irrevocably agrees to become a Grantor under the Security Agreement with the same force and effect as if it were an original signatory thereto and each of the undersigned hereby (a) agrees to be bound by and comply with all of the terms and provisions of the Security Agreement applicable to it as a Grantor and (b) represents and warrants that the representations and warranties made by it as a Grantor thereunder are true and correct as of the date hereof, unless stated to relate solely to an earlier date, in which case such representations and warranties shall be true and correct as of such earlier date. In furtherance of the foregoing, each reference to a “Grantor” and/or “Grantors” in the Security Agreement shall be deemed to include each of the undersigned. Each of the undersigned Grantors hereby authorizes the Lender to file financing statements describing as the collateral covered thereby “all of the debtor’s personal property or assets, whether now owned or hereafter acquired” or words to that effect, notwithstanding that such wording may be broader in scope than the Collateral described in the Security Agreement.

SECTION 2. Schedules. Each of the undersigned Grantors hereby authorizes the Lender to add the information set forth on the Schedules to this Supplement to the correlative Schedules attached to the Security Agreement.

SECTION 3. Representations. Each of the undersigned Grantors hereby represents and warrants that this Supplement has been duly authorized, executed and delivered by it and that this Supplement and the Security Agreement constitute its legal, valid and binding obligation, enforceable against it in accordance with its terms.

SECTION 4. Full Force of Security Agreement. Except as expressly supplemented hereby, the Security Agreement shall remain in full force and effect in accordance with its terms.

SECTION 5. Severability. Wherever possible each provision of this Supplement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Supplement shall be prohibited by or invalid under such law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Supplement or the Security Agreement.

SECTION 6. Governing Law, Entire Agreement, etc. THIS SUPPLEMENT AND ANY CLAIMS, CONTROVERSY, DISPUTE OR CAUSE OF ACTION (WHETHER IN CONTRACT OR TORT OR OTHERWISE) BASED UPON, ARISING OUT OF OR RELATING TO THIS SECURITY AGREEMENT OR ANY DOCUMENT CONTEMPLATED HEREBY SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK (INCLUDING FOR SUCH PURPOSE SECTIONS 5-1401 AND 5-1402 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK). This Supplement, along with the other Loan Documents, constitutes the entire understanding among the parties hereto with respect to the subject matter thereof and supersedes any prior agreements, written or oral, with respect thereto.

SECTION 7. Effective. This Supplement shall become effective when a counterpart hereof executed by the Grantor shall have been received by the Lender. Delivery of an executed counterpart of a signature page to this Agreement by email (e.g. “pdf” or “tiff”) or telecopy shall be effective as delivery of a manually executed counterpart of this Agreement. The words “execution,” “signed,” “signature,” and words of like import in any Loan Document shall be deemed to include electronic signatures or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act.
