in which such listed item is patented or registered or in which an application for Patent or registration is pending and (z) the application number, the Patent number or registration number and the expiration date. The

Intellectual Property listed in Schedule 3.12(a) as owned by the Company is exclusively owned by the Company free and clear of any Liens, except for Permitted Liens. The Intellectual
Property listed in Schedule 3.12(a) as licensed to the Company is subject to a valid and enforceable license in favor of the Company, free and clear of any Liens, except for Permitted Liens. Each issued Patent and registered trademark listed

information and/or the duty of candor owed to the United States Patent and Trademark Office. To the Knowledge of the Company, each of the Material Patents correctly identifies each and every inventor of the claims thereof as determined in accordance
with the laws of the jurisdiction in which such Material Patent is issued or pending, and the Company has performed appropriate reasonable inquiry with respect to such inventorship. Each Person who has or has had any rights in or to the Material
Patents has executed an agreement assigning his, her or its entire right, title and interest in and to such Material Patents, and the inventions embodied, described and/or claimed therein, to the Company, and to the Knowledge of the Company, no such

import, export, offer for sale, distribution, marketing and sale of the Product by the Company does not infringe any Patents that are owned by a Third Party in the Major Countries.

investigation, decree, or any other filed claim (other than routine prosecution before the U.S. Patent and Trademark Office) (collectively referred to hereinafter as “Disputes”) related to any of the Material Patents of which the
Company has received written notice, nor, to the Knowledge of the Company, has any such Dispute been threatened challenging the legality, validity, enforceability or ownership of any Material Patents. There are no Disputes by any Person or Third
Party against the Company, its Licensees or its licensor, and the Company has not received any written notice or claim of any such Dispute as pertaining to the Product. Neither the Company nor its Subsidiaries has sent any notice of any such Dispute
to a Third Party. The Company is not subject to any outstanding injunction, judgment, order, decree, ruling, charge, settlement or other disposition of Dispute which relates to the Product or the Material Patents.

 (c) The Company and its Subsidiaries are in compliance with, and

rules, regulations or standards has been adopted which, when made effective, would reasonably be expected to result in a Material Adverse Effect.

 (c) Purchaser and the Company shall cooperate and provide assistance as reasonably requested by
the other party in connection with any Third Party litigation, arbitration or other Third Party proceeding (whether threatened, existing, initiated, or contemplated prior to, on or after the date hereof) to which any party hereto or any of its

Section 5.07 Put Option; Call Option. 

(a) Put Option. In the event that a Put Option Event shall occur during the Term, Purchaser shall have the right, but not the
obligation (the “Put Option”), exercisable within sixty (60) days of the later of (i) Purchaser’s receipt of written notice from the Company of the Put Option Event or (ii) Purchaser’s discovery that
a Put Option Event has occurred (other than, in either case, with respect to a Bankruptcy Event or a Put Option Event pursuant to clause (d) of said definition, which shall be exercisable immediately by the Purchaser), to require the Company to
repurchase from Purchaser the Assigned Interests at the Put/Call Price. In the event Purchaser elects to exercise its Put Option, Purchaser shall deliver written notice to the Company specifying the closing date which date shall be forty-five
(45) days from such notice date (the “Put Option Closing Date”), which notice must be given within sixty (60) days of Purchaser’s receipt of written notice from the Company of a Put Option Event. Failure to
provide notice by such times will be deemed an irrevocable waiver of the right to exercise the Put Option. On the Put Option Closing Date, the Company shall repurchase from Purchaser the Assigned Interests at the Put/Call Price in cash, the payment
of which shall be made by wire transfer of immediately available funds to the account designated by Purchaser. Notwithstanding anything to the contrary contained herein, immediately upon the occurrence of a Bankruptcy Event, Purchaser shall be
deemed to have automatically and simultaneously elected to have the Company repurchase from Purchaser the Assigned Interests for the Put/Call Price in cash and the Put/Call Price shall be immediately due and payable without any further action or
notice by any party. Immediately upon exercise by Purchaser of the Put Option and the payment by the Company to Purchaser of the Put/Call Price, Purchaser shall be deemed to have automatically assigned to the Company all right, title, and interest
in and to the Assigned Interest.  
 (b) Call Option. At any time after the Closing Date, the Company shall have the
right, but not the obligation (the “Call Option”), exercisable upon ten (10) days’ written notice to Purchaser, to repurchase the Assigned Interests from Purchaser at a repurchase price equal to the Put/Call Price.
In order to exercise the Call Option, the Company shall deliver written notice to Purchaser of its election to so repurchase the Assigned Interests not less than ten (10) days prior to the proposed closing date (the “Call Closing
Date”). On the Call Closing Date, the Company shall repurchase from Purchaser the Assigned Interests at the Put/Call Price, the payment of which shall be made by wire transfer of immediately available funds to the account designated by
Purchaser. Immediately upon exercise by the Company of the Call Option and the payment by the Company to Purchaser of the Put/Call Price, Purchaser shall be deemed to have automatically assigned to the Company all right, title, and interest in and
to the Assigned Interest.

Assigned Interests pursuant to the Put Option or Call Option, Purchaser agrees that it will (i) promptly but no later than three (3) Business Days execute and deliver to the Company such UCC termination statements and other documents as
may be necessary to release Purchaser’s Lien on the Assigned Interests Collateral and otherwise give effect to such repurchase and (ii) take such other actions or provide such other assistance as may be necessary to give effect to such

Concentration Account, a Company Concentration Account and a Purchaser Concentration Account in accordance with the terms herein and therein. Any Purchaser Concentration Account shall be held solely for the benefit of Purchaser, but shall be subject
to the terms and conditions of this Agreement, the Security Agreement and the other Transaction Documents. Funds deposited into the Deposit Account shall be swept by the Deposit Bank on a daily basis into the Joint Concentration Account and
subsequent thereto on a daily basis, the Daily Amount shall be swept into the Purchaser Concentration Account; provided that once the amount of cash swept into the Purchaser Concentration Account during any of the Fiscal Years ended

during the remainder of such Fiscal Year, and shall instead sweep the entirety of funds deposited into the Deposit Account for the balance of such Fiscal Year directly into the Company Concentration Account for immediate and full access by the
Company. Purchaser shall have immediate and full access to any funds held in the Purchaser Concentration Account and such funds shall not be subject to any conditions or restrictions whatsoever, subject to Purchaser’s obligations under
Section 5.08(f). After the Daily Amount is swept into the Purchaser Concentration Account, the amounts remaining in the Joint Concentration Account shall then be swept, automatically or as otherwise directed by the Company, into the
Company Concentration Account. The Company shall have immediate and full access to any funds held in the Company Concentration Account and such funds shall not be subject to any conditions or restrictions whatsoever other than those of the Deposit
Bank; provided, however, that nothing herein shall (i) affect or reduce the Company’s obligations to pay in full all amounts due to Purchaser under this Agreement, or (ii) in any manner limit the recourse of Purchaser to
the Assigned Interests Collateral in accordance with the Security Agreement. 
 (b) The Company shall pay all fees, expenses and charges of
the Deposit Bank.

only until, and to the extent necessary such that, the Back-up Product True-Up Amount due and payable under Section 5.08(f) for that Fiscal Year is paid in full. 

(d) With respect to any License Agreement existing on the date hereof (other than License Agreements to which a European Subsidiary is a party
and License Agreements that do not call for direct payment to the Company or any Subsidiary of the Company), promptly following the entering into the Deposit Agreement, the Company shall or shall instruct such Subsidiary to instruct any party

(e) During the Revenue Interest Period and prior to the termination of this Agreement, the Company shall not have any right to terminate the

(i) Following the end of each Fiscal Quarter, as soon as the Company shall have determined the Applicable Percentage of Net
Revenues of the Product for such Fiscal Quarter and for each other Fiscal Quarter in the Fiscal Year in which the then most recently ended Fiscal Quarter occurred (the “Year-to-Date Applicable Net Revenues”) and in any event no

other Fiscal Quarter in the Fiscal Year in which the then most recently ended Fiscal Quarter occurred, with a reconciliation of such calculation to the Year-to-Date Applicable Net Revenues and the Applicable Percentage of Net Revenues of the Product

will be applicable to the next successive Fiscal Quarter. 
 (ii) If Purchaser has received, on or prior to the last day of
the most recently ended Fiscal Quarter, payments from the Company under Section 2.02 or this Section 5.08 in respect of the Fiscal Year for which Year-to-Date Applicable Net Revenues is calculated under clause (i) above
which are in excess of the Applicable Percentage of Year-to-Date Net Revenues of the Product (after giving effect to the full Yearly Payment Cap (i.e., no quarterly proration)), Purchaser shall pay such excess to the Company within twenty
(20) Business Days of receipt by Purchaser of the True-Up Statement. 
 (iii) If the Applicable Percentage of
Year-to-Date Net Revenues of the Product (after giving effect to the full Yearly Payment Cap (i.e., no quarterly proration)) is in excess of the amounts Purchaser has received on or prior to the last day of the most recently ended Fiscal Quarter in

account of the Back-up Product), after taking into account any true-up adjustments made pursuant to Sections 5.08(f)(ii) or (iii) above, plus any Make-Whole Payment under
Section 2.04 received by Purchaser in such Fiscal Year (the “Back-Up Product True-Up Amount”). The Back-up Product True-up Statement shall also include a reconciliation against any remaining amounts held in the
Brigatinib Divestiture Account (if applicable) and any debits or sweeps made to or out of such Account. 
 (v) If the Back-Up
Product True-Up Amount calculated pursuant to clause (iv) above is positive for a Fiscal Year, the Company shall pay to Purchaser such Back-up Product True-Up Amount solely to the extent such amount does not exceed the greater of (X) the
Applicable Percentage of Net Revenues of Back-up Product for that Fiscal Year and (Y) [***]% of all worldwide Net Sales of the Back-up Product for such Fiscal Year generated by the Company or any of its Affiliates as well as any Third Party,
pursuant to any license, commercialization, co-promotion, collaboration, distribution, marketing or partnering agreement (the greater of (X) and (Y) being referred to herein as the “Back-up Product True-Up Cap”). The
payment of such Back-up Product True-Up Amount due and owing under Section 5.08(f) shall be satisfied exclusively out of the Net Revenue of the Back-up Product, or in the event of Brigatinib Divestiture Event, exclusively out of the Net
Revenue of the Back-up Product and/or the available amounts held in the Brigatinib Divestiture Collateral Account established in accordance with Section 5.17. 

(vi) In the event the Net Revenues of the Back-Up Product received by the Company for that Fiscal Year are not sufficient to
satisfy payment of the Back-up Product True-Up Amount required to be paid under Section 5.08(f) for that Fiscal Year (taking into account any available amounts then held in the Brigatinib Divestiture Collateral Account), no further
amounts shall be due and owing by the Company to Purchaser on account of the Back-up Product True-Up Amount for that Fiscal Year. Any shortfall resulting from the failure of the Net Revenue of the Back-Up Product received by the Company for that
Fiscal Year (or the funds available in the Brigatinib Divestiture Account, if applicable) to satisfy payment of the Back-up Product True-Up Amount required to be paid under Section 5.08(f) for that Fiscal Year shall impose no obligation
on the Company to make any additional payment to the Purchaser pursuant to this clause (v), and such deficiency shall not carry over to any subsequent Fiscal Year. Payment of the Back-up Product True-Up Amount required to be paid hereunder shall be
made by the Company to Purchaser within fifteen (15) Business Days of receipt by Purchaser of the True-Up Statement for that Fiscal Year. 

(vii) If the Back-up Product True-Up Amount calculated pursuant to clause (iv) above is negative, no further payments need
be made by the Company to the Purchaser for that Fiscal Year, and any excess payments made by Company to Purchaser in accordance with Section 5.08(c) based on Net Back-up Product Revenues shall be reimbursed to Company by Purchaser
within fifteen (15) Business Days of receipt by Purchaser of the True-Up Statement for that Fiscal Year.

Section 6.01 Term and Termination Date. 

Except as provided in this Section 6.01 and in Section 6.02, this Agreement shall terminate upon expiration of the
Revenue Interest Period (the “Term”). If any payments are accrued hereunder on or prior to that date and are required to be made by one of the Parties hereunder, this Agreement shall remain in full force and effect until any and all
such payments have been made in full, and (except as provided in Section 6.02) solely for that purpose. In addition, this Agreement shall sooner terminate if the Purchaser shall have exercised the Put Option in accordance with
Section 5.07(a) or the Company shall have exercised the Call Option in accordance with Section 5.07(b), in each case upon the payment of the Put/Call Price. In addition, the Company may terminate this Agreement immediately
upon Purchaser’s failure to pay the Additional Purchase Price on the Additional Purchase Price Closing Date or the Second Tranche Purchase Price on the Second Tranche Purchase Price Closing Date in accordance with Section 2.03(d)
and Section 2.03(e), respectively. Upon expiration or termination of this Agreement in accordance with its terms, all right, title, and interest in and to the Assigned Interest shall automatically revert to Company, and Purchaser will
have no further rights in the Assigned Interest, the Back-up Product True-Up Funds, or the Assigned Interest Collateral.

Agreement. 
 (b) Notwithstanding anything to the contrary in this Agreement, in no event shall either party be liable for special, indirect,
incidental, punitive or consequential damages of the other party, whether or not caused by or resulting from the actions of such party or the breach of its covenants, agreements, representations or warranties hereunder, even if such party has been

 Section 7.04 Successors and Assigns. 

The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and
assigns. The Company shall not be entitled to assign any of its obligations and rights under the Transaction Documents without the prior written consent of Purchaser. Solely upon the consent of the Company (which consent may not be unreasonably
withheld, delayed or conditioned), Purchaser may assign any of its obligations or rights under the Transaction Documents without restriction other than to another pharmaceutical company; provided, however, that, notwithstanding the
foregoing, Purchaser may assign any of its obligations or rights under the Transaction Documents to a pharmaceutical company in connection with a change of control of Purchaser by virtue of a merger, sale or issuance of stock or the sale of all or
substantially all of Purchaser’s assets; provided, further, that Purchaser, notwithstanding such assignment, will remain liable under Section 5.08(f) (solely to the extent of any amount subject thereto during the
Fiscal Year as of the date of such assignment) and Section 7.05. 
 Section 7.05 Indemnification. 

(a) The Company hereby indemnifies and holds Purchaser and its Affiliates and any of their respective partners, directors, managers,
members, officers, employees and agents (each, a “Purchaser Indemnified Party”) harmless from and against any and all Losses (including all Losses in connection with any product liability claims or claims of infringement or
misappropriation of any Intellectual Property rights of any Third Parties) incurred or suffered by any Purchaser Indemnified Party arising out of any breach of any representation, warranty or certification made by the Company in any of the
Transaction Documents or the True-Up Statement or any breach of or default under any covenant or agreement by the Company pursuant to any Transaction Document or the True-Up Statement, including any failure by the Company to satisfy any of the
Excluded Liabilities and Obligations.  
 (b) Purchaser hereby indemnifies and holds the Company, its Affiliates and any of
their respective partners, directors, managers, officers, employees and agents (each, a “Company Indemnified Party”) harmless from and against any and all Losses incurred or suffered by a Company Indemnified Party arising out
of any breach of any representation, warranty or certification made by Purchaser in any of the Transaction Documents or any breach of or default under any covenant or agreement by Purchaser pursuant to any Transaction Document.  

(c) If any claim, demand, action or proceeding (including any investigation by any Governmental Authority) shall be brought or alleged against
an indemnified party in respect of which indemnity is to be sought against an indemnifying party pursuant to the preceding paragraphs, the indemnified party shall, promptly after receipt of notice of the commencement of any such claim, demand,
action or proceeding, notify the indemnifying party in writing of the commencement of such claim, demand, action or proceeding, enclosing a copy of all papers 

  
 Portions of this

served, if any; provided, that the omission to so notify such indemnifying party will not relieve the indemnifying party from any liability that it may have to any indemnified party under
the foregoing provisions of this Section 7.05 unless, and only to the extent that, such omission results in the forfeiture of, or has a material adverse effect on the exercise or prosecution of, substantive rights or defenses by the
indemnifying party. In case any such action is brought against an indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may
wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section 7.05 for
any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. In any such proceeding, an indemnified party shall have the right to retain its own
counsel, but the reasonable fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel,
(ii) the indemnifying party has assumed the defense of such proceeding and has failed within a reasonable time to retain counsel reasonably satisfactory to such indemnified party or (iii) the named parties to any such proceeding (including
any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interests between them based on the advice of
such counsel. It is agreed that the indemnifying party shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one separate law firm (in addition to
local counsel where necessary) for all such indemnified parties. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment
for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an
unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding. 
 (d)
Purchaser’s sole remedy shall be to recover any monetary damages associated with a breach, subject to the other terms and provisions contained in this Agreement. 

Section 7.06 No Implied Representations and Warranties. 

Each party acknowledges and agrees that, other than the representations and warranties specifically contained in any of the Transaction
Documents, there are no representations or warranties of either party or any other Person either expressed or implied with respect to the Assigned Interests or the transactions contemplated hereby. Without limiting the foregoing, Purchaser
acknowledges and agrees that (a) Purchaser and its Affiliates, together with its and its Affiliates’ representatives, have made their own investigation of the Product and the Intellectual

Property and are not relying on any implied warranties or upon any representation or warranty whatsoever as to the future amount or potential amount of the Assigned Interests or as to the
creditworthiness of Company and (b) except as expressly set forth in any representation or warranty in a Transaction Document, Purchaser shall have no claim or right to indemnification pursuant to Section 7.05 (or otherwise) with
respect to any information, documents or materials furnished to Purchaser, any of its Affiliates, or any of its or its Affiliates’ representatives, including any information, documents or material made available to Purchaser and its Affiliates
and its Affiliates’ representatives in any data room, presentation, interview or any other form relating to the transactions contemplated hereby. 

Section 7.07 Independent Nature of Relationship. 

(a) The relationship between the Company and Purchaser is solely that of seller and purchaser, and neither Purchaser nor the Company has any
fiduciary or other special relationship with the other or any of their respective Affiliates. Nothing contained herein or in any other Transaction Document shall be deemed to constitute the Company and Purchaser as a partnership, an association, a
joint venture or other kind of entity or legal form for any purposes, including any Tax purposes. 
 (b) No officer or employee or agent of
Purchaser will be located at the premises of the Company or any of its Affiliates, except in connection with an audit performed pursuant to Section 5.02. No officer, manager or employee of Purchaser shall engage in any commercial
activity with the Company or any of its Affiliates other than as contemplated herein and in the other Transaction Documents. 
 (c) The
Company and/or any of its Affiliates shall not at any time obligate Purchaser, or impose on Purchaser any obligation, in any manner or respect to any Person not a party hereto. 

Section 7.08 Tax Treatment. 

The Purchaser and the Company acknowledge (a) that, for U.S. federal income tax purposes, they agree to treat the rights and interests in
and to the Assigned Interests that are transferred pursuant to this Agreement as indebtedness subject to the U.S. Treasury Regulations Section 1.1275-4 governing contingent payment debt instruments, (b) that the rights in respect of the
Closing Purchase Price, the Additional Purchase Price, and each Second Tranche Purchase Price (if any) represent separate debt instruments for U.S. federal income tax purposes; and (c) that the Purchaser will report original issue discount and
interest on each such debt instrument in accordance with the Company’s determination of both the “comparable yield” and the “projected payment schedule” for such debt instrument, which determination shall be subject to the
prior good faith consultation by the Company with the Purchaser. For this purpose, the “comparable yield” and the “projected payment schedule” relating to the Assigned Interests may be obtained by contacting the Company at the
address set forth in Section 7.03. The parties hereto agree not to take any position that is inconsistent with the provisions of this Section 7.08 on any tax return or in any audit or other administrative or judicial proceeding unless
(i) the other parties to this Agreement have consented in writing to such actions, which consent shall not be unreasonably withheld or delayed, or (ii) the party that contemplates taking such an inconsistent position has been advised by
nationally recognized counsel or tax advisors in writing that it is more likely than not that there is no “reasonable basis” (within the meaning of Treasury Regulation Section 1.6662- 3(b)(3)) for the position specified in this
Section 7.08.

provided by law. 
 Section 7.11 Interpretation. 

When a reference is made in this Agreement to Articles, Sections, Schedules or Exhibits, such reference shall be to an Article, Section,

Company, and at the sole expense of the Company, to execute and deliver such documents as the Company may reasonably request to evidence such release.

 FORM OF ASSIGNMENT OF INTERESTS 

ASSIGNMENT OF INTERESTS 

This ASSIGNMENT OF INTERESTS (this “Assignment”), dated as of July 28, 2015, is made and entered into
by and between ARIAD Pharmaceuticals, Inc., a Delaware corporation (the “Assignor”), and PDL BioPharma, Inc., a Delaware corporation (the “Assignee”). 

WHEREAS, the Assignor and the Assignee are parties to that certain Revenue Interest Assignment Agreement, dated even date herewith
(the “Revenue Interest Assignment Agreement”), pursuant to which, among other things, the Assignor agrees to sell, assign, transfer and convey to the Assignee, and the Assignee agrees to purchase, acquire and accept from the
Assignor, all of the Assignor’s right, title and interest in and to the Assigned Interests, as that term is defined in the Revenue Interest Assignment Agreement, for consideration in the amount and on the terms and conditions provided therein;

 WHEREAS, the parties now desire to carry out the purposes of the Revenue Interest Assignment Agreement by the execution and
delivery of this instrument evidencing the Assignor’s sale, assignment, transfer and conveyance, and Assignee’s purchase, acquisition and acceptance, of the Assigned Interests; and 

WHEREAS, capitalized terms used and not defined herein have the meanings given to them in the Revenue Interest Assignment Agreement.

 NOW, THEREFORE, in consideration of the foregoing premises and of other valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the parties hereto hereby agree as follows: 
 1. Assignment of Assigned Rights. The Assignor
hereby sells, assigns, transfers and conveys to the Assignee free and clear of all Liens (other than Permitted Liens), and the Assignee hereby purchases, acquires and accepts, all of the Assignor’s rights and interest in and to the Assigned
Interests on the Closing Date. 
 2. No Assumption of Obligations. The parties hereto acknowledge that the Assignee is

	•	 	The Company has the corporate power and authority to enter into and perform its obligations under the Transaction Documents to which it is a party, has taken all necessary corporate action to authorize the execution,
delivery and performance of such Transaction Documents and has duly executed and delivered such Transaction Documents. 

  

	•	 	Each Transaction Document to which the Company is a party is the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms. 


 

	•	 	The execution and delivery by the Company of the Transaction Documents to which it is a party do not, and the compliance by the Company with its obligations thereunder will not, (i) result in a violation of the
Certificate of Incorporation and the Bylaws of the Company, (ii) result in a breach or default under any material agreement of the Company, (iii) result in a violation of any order binding upon the Company or (iv) to our knowledge,
result in or require the creation or imposition of any lien or encumbrance upon any assets of the Company under any material agreement of the Company (for the avoidance of doubt, any liens and security interests created pursuant to the Transaction
Documents are excluded from this clause), and any material contracts or binding orders may be identified in a backup officer’s certificate from the Company. 

  


	•	 	The execution and delivery by the Company of the Transaction Documents to which it is a party do not, and the compliance by each of the Company with its obligations thereunder will not, require any approval from or
filing with any governmental authority of the United States, the State of New York, or the State of Delaware, other than the filings and records contemplated by the Transaction Documents to perfect security interests. 


 

	•	 	The execution and delivery by each of the Company of the Transaction Documents to which it is a party do not, and the compliance by the Company with its obligations thereunder will not, result in any violation of any
federal law of the United States, the law of the State of New York or any regulation thereunder, or the law of the State of Delaware or any regulation thereunder, which, in our experience are applicable to, or relevant in connection with,
transactions of the type provided for in the Transaction Documents. 

  

	•	 	Neither the Company nor any Subsidiary of the Company is an “investment company” within the meaning of, and subject to regulation under, the Investment Company Act of 1940, as amended. 


 

	•	 	The Security Agreement is effective to create in favor of the Purchaser, as security for the Secured Obligations, as defined in the Security Agreement, a security interest (the “Article 9 Security
