 3.2. To the extent that any invention included within the LICENSED PATENTS has been funded
in whole or in part by the United States government, the United States government retains certain rights in such invention as set forth in 35 U.S.C. §200-212 and all regulations promulgated thereunder, as amended, and any successor statutes and
regulations (the “Federal Patent Policy”). As a condition of the LICENSE granted hereby, LICENSEE acknowledges and shall comply with all aspects of the Federal Patent Policy applicable to the LICENSED PATENTS, including, solely if and to
the extent applicable, the obligation that LICENSED PRODUCTS used or sold in the United States be manufactured substantially in the United States. Nothing contained in this Agreement obligates or shall obligate YALE to take any action that would
conflict in any respect with its past, current or future obligations to the United States Government under the Federal Patent Policy with respect to the LICENSED PATENTS. 
 3.3. The LICENSE is expressly made subject to YALE’s reservation of the right, on behalf of itself and all other non-profit academic research institutions, to make, use and practice the LICENSED
PATENTS and LICENSED METHODS for research, clinical, teaching or other non-commercial purposes, and not for purposes, whether itself or through any licensee or other third party, of commercial development, use, manufacture or distribution. Nothing
in this Agreement shall be construed to grant by implication, estoppel or otherwise any licenses under patents of YALE other than the LICENSED PATENTS. 
 3.4. Unless terminated earlier as provided in Article 13, the royalty term of this Agreement (the “ROYALTY TERM”) shall commence on the EFFECTIVE DATE and shall automatically expire, for
purposes of any country, on the date on which the last of the LICENSED PATENTS in such country that include at least one VALID CLAIM expires. The term of this Agreement (the “TERM”) shall expire upon expiration of the last-to-expire
ROYALTY TERM or, if earlier, upon the effective date of termination in accordance with Article 13. 
 3.5. Except as expressly
provided in this Agreement, under no circumstances will LICENSEE, as a result of this Agreement, obtain any interest in or any other right to any technology, know-how, patents, patent applications, materials or other intellectual or proprietary
property of YALE. 
 ARTICLE 4 SUBLICENSES 

4.1. LICENSEE may sublicense the rights granted to it under this Agreement without the consent of YALE. 

4.2. Any sublicense granted by LICENSEE shall include provisions designed to protect CONFIDENTIAL INFORMATION and substantially the same

(and all amendments thereof) promptly after execution. LICENSEE shall remain responsible for the performance of all SUBLICENSEES under any such sublicense as if such performance were carried out by LICENSEE itself, including, without limitation, the
payment of any royalties or other payments provided for hereunder, regardless of whether the terms of any sublicense provide for such amounts to be paid by the SUBLICENSEE directly to YALE. 

4.3. LICENSEE shall pay royalties to YALE on NET SALES of SUBLICENSEES based on the same royalty rate as apply to NET SALES by LICENSEE
and its AFFILIATES, regardless of the royalty rates payable by SUBLICENSEES to LICENSEE under a sublicense agreement. In addition, LICENSEE shall pay to YALE [********] ([********]) of any SUBLICENSE INCOME. 

  
 6 

 4.4. LICENSEE agrees that it has sole responsibility to promptly notify YALE of termination

 ARTICLE 5 LICENSE INITIATION FEE; MILESTONE; ROYALTIES 

5.1. LICENSEE shall pay to YALE, (i) a non-refundable license initiation fee of Twenty-Five Thousand Dollars ($25,000.00) and
(ii) the amount of Twenty-Two Thousand, Four Hundred Nineteen Dollars and 30/100 ($22,419.30) to reimburse YALE for all expenses incurred as of the EFFECTIVE DATE in the filing, prosecution, and maintenance of the LICENSED PATENTS. 

5.2. LICENSEE shall make the following non-refundable milestone payments to YALE within thirty (30) days after the applicable
milestone event(s) set forth below: 
 (a) Fifty Thousand Dollars ($50,000.00) (i) upon the issuance of
the first U.S. patent included in the LICENSED PATENTS that would be infringed, in the absence of a license from YALE, by the commercial sale by LICENSEE of mecamylamine hydrochloride together with citalopram hydrobromide or (ii) if the first
to issue U.S. patent included in the LICENSED PATENTS would not be infringed, in the absence of a license from YALE, by the commercial sale by LICENSEE of mecamylamine hydrochloride together with citalopram hydrobromide, upon the sixtieth (60th) day after the date on which LICENSEE pays the issuance fee
(following receipt of the notice of allowance) for such U.S. patent. 
 (b) [********] ($[********]) when LICENSEE or any of its
SUBLICENSEES or AFFILIATES files an NDA for each LICENSED PRODUCT developed by LICENSEE. 
 (c) [********] ($[********]) upon
the FIRST SALE of each LICENSED PRODUCT developed by LICENSEE. 
 For purposes of clarity, the racemate and enantiomers of any compound shall be
considered to be the same compound such that, to the extent that any of the racemate or either of the enantiomers is contained in or comprises a LICENSED PRODUCT, such racemate and enantiomers shall be considered together to be the same LICENSED
PRODUCT and therefore subject to a single milestone stream hereunder. 
 For purposes of further clarity, with respect to each of the foregoing
milestone payments, such milestone payment shall not be due or payable by LICENSEE if this Agreement is terminated pursuant to Article 13 and such termination becomes effective prior to the date on which the event (or, in the case of Article
5.2(a)(ii), the date) giving rise to such milestone payment occurs. 
 5.3. Neither the license initiation fee set forth in
Article 5.1 nor the milestone payments set forth in Article 5.2 shall be credited against EARNED ROYALTIES payable under Article 6. 
 ARTICLE 6 EARNED ROYALTIES; MINIMUM ROYALTY PAYMENTS 
 6.1. During
the TERM, as partial consideration for the LICENSE, LICENSEE shall pay to YALE an earned royalty on cumulative NET SALES of LICENSED PRODUCTS or LICENSED METHODS by LICENSEE or its SUBLICENSEES or AFFILIATES in each calendar (January 1 through
December 31) year (“EARNED ROYALTIES”) according to the following schedule: 

  
 7 

					
	 Annual NET SALES
	  	 Prior to Expiration of the Last

TARGACEPT PATENT
	  	 After Expiration of the last

TARGACEPT PATENT

	 >$[********]
	  	[********]%	  	[********]%
			
	 > $[********]
	  	[********]%	  	[********]%

 By way of example, if cumulative NET SALES of LICENSED PRODUCTS in a particular calendar year are $[********]and there is
at least one unexpired TARGACEPT PATENT, EARNED ROYALTIES payable hereunder would be determined as follows: 
 [********]

 For purposes of clarity, LICENSEE’s obligation to pay EARNED ROYALTIES shall be imposed only once with respect to the same unit of a
LICENSED PRODUCT or LICENSED METHOD regardless of how many LICENSED PATENTS or VALID CLAIMS pertain thereto. 
 6.2.
Notwithstanding Article 6.1, if (i) the practice of any portion of the LICENSE (including, without limitation, the sale of LICENSED PRODUCTS or LICENSED METHODS), or the manufacture, use, sale or other exploitation of a LICENSED PRODUCT or
LICENSED METHOD, by LICENSEE or any of its AFFILIATES or SUBLICENSEES in a particular country would or would reasonably be expected to infringe upon an issued patent of a third party in the absence of a license (whether or not any other LICENSED
PRODUCT or LICENSED METHOD could be manufactured, used, sold or otherwise exploited without a license to such third party patent) and (ii) LICENSEE or any of its AFFILIATES or SUBLICENSEES obtains a license to such third party patent, the
amount of EARNED ROYALTIES payable by LICENSEE shall be reduced by an amount equal to the lesser of (A) [********] ([********]) of the amounts paid to secure such third party license or (B) the amount that results in aggregate EARNED
ROYALTIES of at least [********]of NET SALES for such calendar quarter. 
 6.3. LICENSEE shall pay all EARNED ROYALTIES accruing
to YALE within ninety (90) days from the end of each calendar quarter (i.e., March 31, June 30, September 30 and December 31), beginning in the first calendar quarter in which NET SALES occur. 

6.4. During the TERM, LICENSEE agrees to pay YALE annual Minimum Royalty Payments (“MRP”), commencing after the first
anniversary of the date of the FIRST SALE of the first LICENSED PRODUCT or LICENSED METHOD. The MRP shall be in the following amounts: 
  

			
	 1st anniversary of FIRST SALE
	  	$[********]
		
	 2nd anniversary of FIRST SALE
	  	$[********]
		
	 3rd anniversary of FIRST SALE

and every anniversary of FIRST SALE thereafter
	  	$[********]

  
 8 

 Each MRP shall be payable by LICENSEE on the anniversary of the EFFECTIVE DATE that first occurs after the
applicable anniversary of FIRST SALE. 
 6.5. LICENSEE shall continue to pay the MRP until the end of the TERM. YALE shall fully
credit each MRP made against any EARNED ROYALTIES payable by LICENSEE in the same year and thereafter until exhausted. 
 6.6.
All EARNED ROYALTIES and other payments due under this Agreement shall be paid to YALE in United States Dollars. In the event that conversion from foreign currency is required in calculating a payment under this Agreement, the exchange rate used
shall be the Interbank rate quoted by Citibank at the end of the last business day of the quarter in which the royalty was earned. If overdue, the royalties and any other payments due under this Agreement shall bear interest until payment at a per
annum rate two percent (2%) above the prime rate in effect at Citibank on the due date and YALE shall be entitled to recover reasonable attorneys’ fees and costs related to the enforcement of this Agreement to collect such payment. The
payment of such interest shall not foreclose YALE from exercising any other right it may have as a consequence of the failure of LICENSEE to make any payment when due. 
 ARTICLE 7 DUE DILIGENCE 
 7.1. LICENSEE shall use all REASONABLE
COMMERCIAL EFFORTS to develop at least one LICENSED PRODUCT or LICENSED METHOD for commercialization in the United States. Failure to do so shall, if determined to be a material breach and subject to the applicable cure period, be subject to
termination under Article 13. 
 7.2. Within sixty (60) days after each anniversary of the EFFECTIVE DATE, LICENSEE shall
provide a written report to YALE summarizing LICENSEE’s progress in its development or commercialization of at least one LICENSED PRODUCT or LICENSED METHOD; provided that such reporting obligation shall expire upon the FIRST SALE of at least
one LICENSED PRODUCT. 
 7.3. LICENSEE shall immediately notify YALE if at any time LICENSEE finally abandons both its research,
development or marketing of LICENSED PRODUCTS and LICENSED METHODS and its intent to research, develop and market such products or methods. 
 7.4. Without prejudice to YALE’s rights under Article 13, LICENSEE agrees that YALE shall be entitled to terminate this Agreement if LICENSEE provides YALE with the notice set forth in Article 7.3.

 ARTICLE 8 CONFIDENTIALITY AND PUBLICITY 

8.1. Subject to the parties’ rights and obligations pursuant to this Agreement, YALE and LICENSEE agree that during the TERM and for

equity financing, (iv) to any actual or potential SUBLICENSEE or (v) in connection with any acquisition or business combination; provided that, in case of clauses (iv) or (v), any such disclosure is made subject to an obligation of
confidentiality at least substantially similar to those contained herein; and

receipt of written request from a party following termination of this Agreement, return all the CONFIDENTIAL INFORMATION disclosed to it by the other party pursuant to this Agreement, except for one copy which may be retained by the recipient for
monitoring compliance with this Article 8. 
 8.2. The obligations of non-use and confidentiality described above shall not
pertain to that part of the CONFIDENTIAL INFORMATION that: 
 (a) was known to the recipient prior to the disclosure by the
disclosing party; or 
 (b) is at the time of disclosure or has become thereafter publicly known through no fault or omission
attributable to the recipient; or 
 (c) is rightfully given to the recipient from sources independent of the disclosing party;
or

certified public accountant selected by YALE, at YALE’s expense, during normal business hours upon thirty (30) days prior written notice, for the purpose of verifying the accuracy of the reports and computations rendered by LICENSEE. In
the event LICENSEE underpaid the amounts due to YALE with respect to the audited period by more than five percent (5%), LICENSEE shall pay the reasonable cost of such examination, together with the deficiency not previously paid, within thirty
(30) days of receiving notice thereof from YALE. 
 9.3. On or before the ninetieth (90th) day following the close of LICENSEE’s fiscal year,
LICENSEE shall provide YALE with LICENSEE’s certified financial statements for the preceding fiscal year including, at a minimum, a balance sheet and an income statement. This Article 9.3 shall not apply if and for so long as LICENSEE has a
class of securities registered under Section 12 of the Securities Exchange Act of 1934.

 ARTICLE 10 PATENT PROTECTION 

10.1. From and after the EFFECTIVE DATE, LICENSEE shall be responsible for all actually incurred, reasonable costs of filing, prosecution
and maintenance of all United States patent applications contained in the LICENSED PATENTS. Any and all such United States patent applications, and resulting issued patents, shall remain the property of YALE. 

10.2. From and after the EFFECTIVE DATE, LICENSEE shall be responsible for all actually incurred, reasonable costs of filing, prosecution
and maintenance of all foreign patent applications, and patents contained in the LICENSED PATENTS in countries outside the United States in the LICENSED TERRITORY selected by LICENSEE with the consent of YALE, not to be unreasonably withheld,
conditioned or delayed. All such applications or patents shall remain the property of YALE. 
 10.3. If LICENSEE fails to pay
the expenses of filing, prosecuting or maintaining a LICENSED PATENT in the United States, then LICENSEE’s rights under this Agreement shall terminate automatically with respect to such LICENSED PATENT in the United States. 

10.4. The costs mentioned in Articles 10.1 and 10.2 shall include, but are not limited to, taxes, annuities, working fees, maintenance
fees and renewal and extension charges. Payment of such costs shall be made, at YALE’s option, either directly to patent counsel or by reimbursement to YALE. In either case, LICENSEE shall make payment directly to the appropriate party within
thirty (30) days after receiving its invoice. 
 10.5.    (a) Subject to this Article 10.5, all pending
patent applications and issued patents included in the LICENSED PATENTS shall be prepared, prosecuted, filed and maintained by outside patent counsel chosen by YALE subject to the approval of LICENSEE, not to be unreasonably withheld. YALE shall
instruct patent counsel to (i) keep both YALE and LICENSEE regularly informed of the progress of the prosecution, issuance and maintenance of all such patent applications and patents, (ii) make itself available with reasonable notice, at
reasonable times and with reasonable frequency for consultation with LICENSEE and its outside patent counsel, (iii) give both YALE and LICENSEE reasonable opportunity to review and comment on the type and scope of useful claims and the nature
of supporting disclosures, (iv) give due consideration in good faith to comments received from LICENSEE or its outside patent counsel and (v) give LICENSEE at least thirty (30) days prior written notice of all meetings and material
communications with any patent authorities concerning the LICENSED PATENTS and to permit LICENSEE to participate in such meetings or communications. YALE will not finally abandon any patent application included in the LICENSED PATENTS without
LICENSEE’s prior written consent. LICENSEE shall have the sole right, in good faith, to determine whether to seek or obtain any patent term extension(s), restoration(s) or the like that may be available in the future with respect to the
LICENSED PATENTS in any part of the LICENSED TERRITORY. Neither party shall have any liability to the other party for damages, whether direct, indirect or incidental, consequential or otherwise, arising from its good faith decisions, actions and
omissions in connection with patent prosecution hereunder if such party shall have complied with its obligations under this Article 10.5(a). 
 (b) Notwithstanding Article 10.5(a), upon thirty (30) days written notice to YALE, LICENSEE (or its AFFILIATES or SUBLICENSEES) shall have the right to assume the sole responsibility for the
preparation, prosecution, filing and maintenance, by outside patent counsel chosen thereby and reasonably acceptable to YALE, of all pending patent applications and issued 

  
 12 

 
patents included in the LICENSED PATENTS; provided that such rights shall be expressly subject to the obligations of LICENSEE (or, as applicable, its AFFILIATES or SUBLICENSEES) to instruct
patent counsel to (i) [********], (ii) keep YALE regularly informed of the progress, issuance and maintenance of all such patent applications and patents, (iii) give YALE reasonable opportunity to comment on the type and scope of
useful claims and the nature of supporting disclosures, (iv) give due consideration in good faith to comments received from YALE or its outside patent counsel, (v) not make any changes that would materially limit either the scope or number
of claims without YALE’s prior written consent and (vi) not to finally abandon any patent application included in the LICENSED PATENTS without YALE’s prior written consent. 

10.6. LICENSEE shall mark, and shall contract with its SUBLICENSEES to mark, all LICENSED PRODUCTS with the numbers of all patents
included in LICENSED PATENTS that cover the LICENSED PRODUCTS. Without limiting the foregoing, all LICENSED PRODUCTS shall be marked in such a manner as to conform with the patent marking notices required by the law of any country where such
LICENSED PRODUCTS are made, sold, used or shipped, including, but not limited to, the applicable patent laws of that country. 

ARTICLE 11 INFRINGEMENT AND LITIGATION 
 11.1. Each party shall promptly notify the other in writing in the event that it obtains knowledge of infringing activity by third parties, or is sued or threatened with an infringement suit, in any
country in the LICENSED TERRITORY as a result of activities that concern the LICENSED PATENTS and shall supply the other party with documentation of the infringing activities that it possesses, if any. 

11.2. During the TERM: 
 (a) LICENSEE shall have the first right, but shall not be obligated, to defend the LICENSED PATENTS against infringement or interference in the FIELD and in the LICENSED TERRITORY by third parties. This
right includes bringing any legal action for infringement and defending any counterclaim of invalidity or action of a third party for declaratory judgment for non-infringement or non-interference. If, in the reasonable opinion of LICENSEE’s and
YALE’s respective counsels, YALE is required to be a named party to any such suit for standing purposes, LICENSEE may join YALE as a party; provided, however, that (i) YALE shall not be the first named party in any such action,
(ii) the pleadings and any public statements about the action shall state that the action is being pursued by LICENSEE and that LICENSEE has joined YALE as a party; and (iii) LICENSEE shall keep YALE reasonably apprised of all material
developments in any such action. LICENSEE may settle such suits, whether by agreement, consent, judgment, voluntary dismissal or otherwise, solely in its own name and solely at its own expense and through counsel of its own selection; provided,
however, that any such settlement that imposes any restrictions or obligations on YALE shall be entered into only with YALE’s prior written consent. LICENSEE shall bear the expense of such legal actions. Except for providing reasonable
assistance, at the request and reasonable expense of LICENSEE, YALE shall have no obligation regarding the legal actions described in Article 11.2 unless required to participate by law. However, YALE shall have the right to participate in any such
action through its own counsel and at its own expense. Any recovery shall first be applied to LICENSEE’s out of pocket expenses and second to YALE’s out of pocket expenses, in each case including legal fees. If there is any excess recovery
following payment of such expenses: (A) any amount recovered specifically for lost profits or sales shall be treated as NET SALES in the calendar quarter in which such recovery is paid and shall be subject to EARNED

  
 13 

 
ROYALTIES payable to YALE in respect of such NET SALES; (B) any amount recovered specifically as punitive or treble damages shall be treated as SUBLICENSE INCOME; and (C) if both clause
(A) and clause (B) apply, the amount of such excess recovery shall apply to clause (A) and clause (B) in the same proportion as (1) the amount recovered specifically for lost profits or sales bears to (2) the amount
recovered specifically as punitive or treble damages. 
 (b) In the event LICENSEE fails to initiate and pursue commercially
reasonable steps within one hundred twenty (120) days of (i) notification of infringement from YALE to eliminate the infringement or interference or (ii) the date LICENSEE otherwise first becomes aware of an infringement, whichever is
earlier, YALE shall have the right to initiate such legal action at its own expense. If, in the reasonable opinion of YALE’s and LICENSEE’s respective counsel, LICENSEE is required to be a named party in any such suit for standing
purposes, YALE may join LICENSEE as a party, subject to the same conditions to the joining of YALE set forth in Article 11.2(a). In such case, LICENSEE shall provide reasonable assistance to YALE if requested to do so. YALE may settle, whether by
agreement, consent, judgment, voluntary dismissal or otherwise, such actions solely through its own counsel; provided, however, that any such settlement that imposes any restrictions or obligations on LICENSEE shall be entered into only with
LICENSEE’s prior written consent. Any recovery shall be retained by YALE. 
 11.3. In the event LICENSEE is permanently
enjoined from exercising its LICENSE under this Agreement pursuant to an infringement action brought by a third party, or if both LICENSEE and YALE elect not to undertake the defense or settlement of a suit alleging infringement for a period of six
(6) months from notice of such suit, then either party shall have the right to remove the country where the suit was filed from the LICENSED TERRITORY upon thirty (30) days written notice to the other party in accordance with the terms of
Article 15. 
 ARTICLE 12 USE OF YALE’S NAME 

LICENSEE shall not use the name “Yale” or “Yale University,” or any variation or adaptation thereof, or any
trademark, tradename or other designation owned by YALE, or the names of any of its trustees, officers, faculty, students, employees or agents, for any purpose without the prior written consent of YALE in each instance, except that LICENSEE may
state that it has licensed from YALE one or more of the patents and applications comprising the LICENSED PATENTS. YALE shall not use the name “Targacept” or any variation or adaptation thereof, or any trademark, tradename or other
designation owned by LICENSEE, or the names of any of its directors, officers, employees or agents, for any purpose without the prior written consent of LICENSEE in each instance, except that YALE may state that LICENSEE has licensed from it one or
more of the patents and applications comprising the LICENSED PATENTS. 
 ARTICLE 13 TERMINATION 

13.1. YALE shall have the right to terminate this Agreement upon written notice to LICENSEE in the event LICENSEE: 

(a) fails to make any payment whatsoever due and payable pursuant to this Agreement unless LICENSEE shall make all such payments (and all
interest due on such payments under Article 6.4) within the thirty (30) day period after receipt of written notice from YALE; or 

  
 14 

 (b) subject to Article 16.3, commits a material breach of any other provision of this
Agreement which is not cured (if capable of being cured) within the one hundred twenty (120) day period after receipt of written notice thereof from YALE (or upon receipt of such notice if such breach is not capable of being cured); 

(c) fails to obtain or maintain adequate insurance as described in Article 14 and does not cure such breach within the ten (10) day
period after receipt of written notice thereof from YALE; 
 (d) as provided in Article 7.4. 

13.2. This Agreement shall terminate automatically without any notice to LICENSEE in the event LICENSEE shall cease to carry on its
business or becomes INSOLVENT, or a petition in bankruptcy is filed against LICENSEE and is consented to, acquiesced in or remains undismissed for sixty (60) days, or LICENSEE makes a general assignment for the benefit of creditors, or a
receiver is appointed for LICENSEE. 
 13.3. LICENSEE shall have the right to terminate this Agreement upon thirty
(30) days prior written notice to YALE. 
 13.4. Upon termination of this Agreement for any reason (but, for purposes of
clarity, not expiration of the TERM), all rights and licenses granted to LICENSEE under the terms of this Agreement are terminated and YALE has the option, in its discretion, to terminate any sublicense granted by LICENSEE. Upon such termination
(but not expiration of the TERM), LICENSEE shall cease to manufacture or sell LICENSED PRODUCTS and cease to practice LICENSED METHODS; provided that, as applied to the terms “LICENSED PRODUCTS” and “LICENSED METHODS” as used in
this Article 13.4 and notwithstanding Article 2.24, “VALID CLAIM” shall, mean (i) a valid and enforceable claim of an issued and unexpired LICENSED PATENT or (ii) a claim of a pending application included in LICENSED PATENTS that
is being prosecuted in good faith and that has not been irrevocably abandoned or finally disallowed without the possibility of appeal or re-filing where such claim, if such patent application were to issue as a patent, would be valid and
enforceable. Within sixty (60) days after the effective date of termination LICENSEE shall deliver to YALE: 
 (a) the last
report required under Article 7 or 9; and 
 (b) all payments incurred up to the effective date of termination. 

13.5. Termination of this Agreement shall not affect any rights or obligations accrued prior to the effective date of such termination
and specifically LICENSEE’s obligation to pay all such accrued royalties and other payments specified by Article 5 and 6. The following provisions shall survive any termination: Articles 2 and 8, Article 9.2, Article 10.5 (last sentence only),
Article 12, this Article 13.5, Article 14, Article 15, Article 16.1, Article 16.3 and Article 17. The parties agree that claims giving rise to indemnification may arise after the TERM or termination of the LICENSE granted herein. 

13.6. The rights provided in this Article 13 shall be in addition and without prejudice to any other rights which the parties may have
with respect to any default or breach of the provisions of this Agreement. 

  
 15 

 13.7. Waiver by either party of one or more defaults or breaches shall not deprive such
party of the right to terminate because of any subsequent default or breach. 
 ARTICLE 14 INDEMNIFICATION; INSURANCE;
WARRANTIES AND DISCLAIMERS 
 14.1. LICENSEE shall defend, indemnify and hold harmless YALE, its trustees, directors,
officers, employees, and agents and their respective successors, heirs and assigns (“Indemnified Parties”) against any and all liabilities, claims, demands, damages, judgments and expenses of any nature, including without limitation legal
expenses and reasonable attorneys’ fees, under any theory of liability (including, without limitation, tort, warranty, or strict liability), arising out of the death, personal injury or illness of any person, or damage to any property,
resulting from the production, manufacture, sale, use, lease or other disposition or consumption, promotion or advertisement of the LICENSED PRODUCTS or LICENSED METHODS by LICENSEE, its AFFILIATES, SUBLICENSEES; provided that LICENSEE shall have no
obligation hereunder to Indemnified Parties with respect to liabilities, claims or demands (“Claims”), damages, judgments, losses and expenses to the extent that they arise out of the gross negligence or willful misconduct of any
Indemnified Party. 
 14.2. YALE shall give LICENSEE prompt (and, in any event, within thirty (30) days after YALE’s
receipt of written notice of a Claim) written notice of any Claim asserted for which any Indemnified Party seeks to enforce Article 14.1, specifying in an amount of detail reasonable under the circumstances the nature of the Claim; provided that the
failure to provide such notice on a timely basis shall not relieve LICENSEE of any obligation that it may have under Article 14.1, except to the extent that the defense of such Claim is materially prejudiced by such failure. LICENSEE shall have the
opportunity to defend, negotiate and settle such claims using counsel of its choice; provided, however, that (i) any Indemnified Party shall be entitled to participate in the defense of such matter and to employ, at its expense, counsel to
assist therein and (ii) LICENSEE shall not be responsible or bound by any settlement of any Claim without its prior written consent. YALE shall ensure that all Indemnified Parties seeking to enforce Article 14.1 provide LICENSEE with such
information and assistance as LICENSEE may reasonably request, at the reasonable expense of LICENSEE. 
 14.3. LICENSEE shall
purchase and maintain in effect during the TERM, and shall require its SUBLICENSEES (other than QUALIFIED SUBLICENSEES which may elect to self-insure and other than SUBLICENSEES with rights limited to in vitro and animal research) to purchase
and maintain in effect during the TERM, a policy of general liability insurance. Such insurance shall: 
 (a) list “YALE,
its trustees, directors, officers, employees and agents” as additional insureds under the policy and provide for thirty (30) days written notice prior to any cancellation or material change to the policy(ies); and 

(b) be endorsed such that it provides contractual liability coverage for LICENSEE’s indemnification under Article 14.1. 

In addition, LICENSEE shall purchase and maintain in effect during the TERM a policy covering product liability in amounts no less than
$[********]Dollars per incident and $[********]Dollars annual aggregate; provided that, by virtue of such minimum amount of coverage required, such insurance not be construed to create a limit of LICENSEE’s liability with respect to its
indemnification under Article 14.1. 

  
 16 

 14.4. By signing this Agreement, LICENSEE certifies that the requirements of
Article 14.3 will be met on or before the earlier of (a) the date of FIRST SALE of any LICENSED PRODUCT or LICENSED METHOD or (b) the first date, after the EFFECTIVE DATE, any LICENSED PRODUCT or LICENSED METHOD is tested or used by
LICENSEE, a SUBLICENSEE or an AFFILIATE on humans, and will continue to be met thereafter. Upon YALE’s request during the TERM, LICENSEE shall furnish a Certificate of Insurance and a copy of the current insurance policy(ies) to YALE.

 14.5. YALE represents and warrants to LICENSEE that (i) to YALE’s knowledge, the INVENTORS are the only persons who
contributed to either the conception or first reduction to practice of the INVENTION, (ii) each INVENTOR was an employee of YALE at the time the INVENTION was first disclosed to YALE’s Office of Cooperative Research, (iii) YALE has
secured a valid and binding written assignment to the INVENTION (including, without limitation, the LICENSED PATENTS) from each INVENTOR, (iv) YALE has made due inquiry of each INVENTOR and has no reason to believe that any such INVENTOR has
granted, purported to grant or agreed to grant any right or license to the INVENTION or any of the LICENSED PATENTS to any third party, (v) to YALE’s knowledge, YALE owns all right, title and interest in and to the LICENSED PATENTS,
(vi)YALE has the lawful right to grant the LICENSE, (vii)YALE has not granted rights or licenses in derogation of this Agreement other than those rights granted or reserved to the U.S. Government, (viii) to YALE’s knowledge, the LICENSED
PATENTS are not invalid or unenforceable and (ix) in respect of the pending U.S. patent application included in the LICENSED PATENTS, YALE has presented all relevant prior art of which YALE and, to YALE’s knowledge, the INVENTORS have
knowledge to the relevant Patent Examiner at the United States Patent and Trademark Office. YALE agrees that, during the TERM, YALE shall not enter into any other agreements that conflict with the rights or obligations provided hereunder, including
any rights and obligations that survive termination of this Agreement. 
 14.6. (a) EXCEPT AS OTHERWISE EXPRESSLY PROVIDED IN
ARTICLE 14.5, YALE MAKES NO, AND EXPRESSLY DISCLAIMS ALL, REPRESENTATIONS OR WARRANTIES THAT ANY CLAIMS OF THE LICENSED PATENTS, ISSUED OR PENDING, ARE VALID, OR THAT THE MANUFACTURE, USE, SALE OR OTHER DISPOSAL OF THE LICENSED PRODUCTS, OR PRACTICE
OF THE LICENSED METHODS DOES NOT OR WILL NOT INFRINGE UPON ANY PATENT OR OTHER RIGHTS NOT VESTED IN YALE. 
 (b) EXCEPT AS
OTHERWISE EXPRESSLY PROVIDED IN ARTICLE 14.5, YALE MAKES NO, AND EXPRESSLY DISCLAIMS ALL, REPRESENTATIONS AND WARRANTIES WHATSOEVER WITH RESPECT TO THE LICENSED PATENTS, LICENSED PRODUCTS AND LICENSED METHODS, EITHER EXPRESS OR IMPLIED, INCLUDING,
BUT NOT LIMITED TO, WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. LICENSEE SHALL MAKE NO STATEMENTS, REPRESENTATION OR WARRANTIES WHATSOEVER TO ANY THIRD PARTIES WHICH ARE INCONSISTENT WITH SUCH DISCLAIMER BY YALE. IN NO EVENT
SHALL YALE, OR ITS TRUSTEES, DIRECTORS, OFFICERS, EMPLOYEES AND AFFILIATES, BE LIABLE FOR SPECIAL, INCIDENTAL, CONSEQUENTIAL OR INDIRECT DAMAGES OF ANY KIND, INCLUDING ECONOMIC DAMAGE OR INJURY TO PROPERTY AND LOST PROFITS, REGARDLESS OF WHETHER
YALE SHALL BE ADVISED, SHALL HAVE OTHER REASON TO KNOW, OR IN FACT SHALL KNOW OF THE POSSIBILITY OF THE FOREGOING. 

  
 17

activities under this Agreement 
 16.3. Neither party shall institute a proceeding in any court or administrative agency to

 18 

 17.3. The provisions of this Agreement shall be deemed separable. If any part of this
Agreement is rendered void, invalid, or unenforceable, such determination shall not affect the validity or enforceability of the remainder of this Agreement unless the part or parts which are void, invalid or unenforceable shall substantially impair

other encumbrance on this Agreement or any sublicense. 
 17.8. The failure of either party to enforce at any time, or for any
period of time, any provision of this Agreement shall not be construed as a waiver of either such provision or of the right of such party thereafter to enforce each and every provision of this Agreement.

 ARTICLE 2 
 THE NOTES 
  

	Section 2.01	Designation, Amount and Issuance of Notes. 

 The Notes shall be designated as “1 3/4% Senior Convertible Notes due 2017.” The Notes shall initially be issued in an aggregate principal amount of $300,000,000, as provided in the Purchase Agreement. Upon the execution of this
Indenture, or from time to time thereafter, Notes may be executed by the Company and delivered to the Trustee for authentication. 
 The Company may, without the consent of Holders, issue additional Notes hereunder in the future on the same terms and conditions of the Notes issued hereunder, except for any differences in the issue
price and interest accrued prior to the issue date of the additional Notes; provided that if any such additional Notes are not fungible with the Notes initially offered hereby for U.S. federal income tax purposes, such additional Notes will
have a separate CUSIP number (such additional Notes, the “Additional Notes”). The Notes initially issued hereunder and any such Additional Notes shall rank equally and ratably and shall be treated as a single class for all purposes
under this Indenture. The Company may not issue any Additional Notes if any Event of Default has occurred and is continuing with respect to the Notes. 
  

	Section 2.02	Form of the Notes. 

 The
Notes and the Trustee’s certificate of authentication to be borne by such Notes shall be substantially in the form set forth in Exhibit A hereto. The terms and provisions contained in the form of Notes attached as Exhibit A hereto
shall constitute, and are hereby expressly made, a part of this Indenture and, to the extent applicable, the Company and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound
thereby. 
 Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends,
endorsements or changes as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of this Indenture, or as may be required by the custodian for the
Global Notes or the Depositary or as may be required for the Notes to be tradable on any market developed for trading of securities pursuant to Rule 144A or as may be required to comply with any applicable law or with any rule or regulation made
pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed, or to conform to usage, or to indicate any special limitations or restrictions to which any particular Notes
are subject. 
 So long as the Notes are eligible for book-entry settlement with the Depositary, or unless otherwise required by
law, or otherwise contemplated by Section 2.08(b), all of the Notes shall be evidenced by one or more Notes in global form registered in the name of the Depositary or the nominee of the Depositary (the “Global Notes”). The
transfer and exchange of beneficial interests in any such Global Notes shall be effected through the Depositary in accordance with 

  
 12 

 
this Indenture and the applicable procedures of the Depositary. Except as provided in Section 2.08(b), beneficial owners of a Global Note shall not be entitled to have certificates
registered in their names, shall not receive or be entitled to receive physical delivery of certificates in definitive registered form and shall not be considered Holders of such Global Note. 

Any Global Notes shall represent such of the outstanding Notes as shall be specified therein and shall provide that it shall represent
the aggregate amount of outstanding Notes from time to time endorsed thereon and that the aggregate amount of outstanding Notes represented thereby may from time to time be increased or reduced on the books and records of the Depositary and Trustee
to reflect repurchases, conversions, transfers or exchanges permitted hereby. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the amount of outstanding Notes represented thereby shall be made by the Trustee or
the custodian for the Global Note, at the direction of the Trustee, in such manner and upon instructions given by the Holder of such Notes in accordance with this Indenture. Payment of principal of and any interest on any Global Notes shall be made
to the Depositary in immediately available funds. 
  

	Section 2.03	Date and Denomination of Notes; Payment at Maturity; Payment of Interest. 

 (a) Date and Denomination. The Notes shall be issuable in fully registered form without interest coupons in denominations of $1,000 principal amount and integral multiples thereof. Each Note shall
be dated the date of its authentication and shall bear interest from the date specified on the face of the Notes. 
 (b)
Payment at Maturity. On the Maturity Date, each Holder shall be entitled to receive on such date, $1,000 in cash for each $1,000 in principal amount of Notes, together with any accrued and unpaid interest thereon to, but excluding, the
Maturity Date, unless such Note is earlier converted or repurchased. With respect to Global Notes, principal and any interest shall be paid to the Depositary by wire transfer of immediately available funds. With respect to any certificated Notes,
principal and any interest shall be payable at the Company’s office or agency in New York City, which initially shall be the office or agency of the Trustee located at the Corporate Trust Office. If the Maturity Date is not a Business Day,
payment shall be made on the next succeeding Business Day, and no additional interest shall accrue thereon. 
 (c) Payment of
Interest. Interest on the Notes shall accrue at the rate of 1.75% per annum from the date of original issuance of the Notes or from the most recent date to which interest has been paid or duly provided for. Interest shall be payable in
arrears on March 1 and September 1 of each year (each, an “Interest Payment Date”), commencing on September 1, 2012, to Holders of record at the close of business on the applicable Regular Record Date. Notwithstanding
the preceding sentence, (i) the Company will not pay in cash accrued interest (excluding any additional interest) on any Notes when such Notes are converted, except as described in Section 10.02, and (ii) with respect to the Interest
Payment Date that falls on the Maturity Date, the Company will pay any accrued and unpaid interest to the Person to whom the Company pays the principal amount (rather than the Holder of record on the corresponding Regular Record Date). 

  
 13 

 The Company shall pay interest on: 

(i) any Global Notes to the Depositary in immediately available funds; 

(ii) any Notes in certificated form having a principal amount of less than $2,000,000, by check mailed to the address of
the Person in whose name such Notes are registered as it appears in the Register; and 
 (iii) any Notes in
certificated form having a principal amount of $2,000,000 or more, by wire transfer in immediately available funds at the election of the Holder of such Notes duly delivered to the Trustee at least five Business Days prior to the relevant Interest
Payment Date. 
 Interest on the Notes shall be calculated on the basis of a 360-day year consisting of twelve 30-day months. If
an Interest Payment Date is not a Business Day, payment shall be made on the next succeeding Business Day, and no additional interest shall accrue thereon. 
 To the extent lawful, payments of principal or interest (including additional interest, if any) on the Notes that are not made when due will accrue interest at the then applicable interest rate on the
Notes from the required payment date. 
  

	Section 2.04	Execution and Authentication. 

 One Officer shall sign the Notes for the Company by manual or facsimile signature. If an Officer whose signature is on a Note no longer holds that office at the time the Trustee authenticates the Note,
the Note shall be valid nevertheless. 
 A Note shall not be valid until an authorized signatory of the Trustee manually
authenticates the Note. Upon the written order of the Company signed by an Officer, the Trustee shall authenticate a Note executed by the Company. The signature of the Trustee on the Note shall be conclusive evidence that the Note has been duly and
validly authenticated under this Indenture. 
 The Trustee may appoint an authenticating agent reasonably acceptable to the
Company to authenticate the Notes. Any such appointment shall be evidenced by an instrument signed by a Responsible Officer, a copy of which shall be furnished to the Company. Unless limited by the terms of such appointment, an authenticating agent
may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for
service of notices and demands. 
  

	Section 2.05	Registrar and Paying Agent. 

 The Company shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (the “Registrar”) and an office or agency where Notes may be
presented for payment (the “Paying Agent”). The Corporate Trust Office shall be considered as one such office or agency of the Company for each of the aforesaid purposes. The 

  
 14 

 
Registrar shall keep a register of the Notes (the “Register”) and of their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying
agents. The term “Paying Agent” includes any additional paying agent, and the term “Registrar” includes any co-registrars. The Company initially appoints the Trustee as (i) Registrar and Paying Agent in connection with the
Notes, (ii) the custodian with respect to the Global Notes and (iii) Conversion Agent. 
 The Company shall enter into
an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this Indenture that relate to such agent. The Company shall notify the Trustee of the name and address
of any such agent. If the Company fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be entitled to appropriate compensation therefore pursuant to Section 7.07. The Company or any of its Wholly Owned
Subsidiaries that is not a Foreign Subsidiary may act as Paying Agent or Registrar. 
 The Company may remove any Registrar or
Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided, however, that no such removal shall become effective until (1) acceptance of an appointment by a successor as evidenced by an appropriate
agreement entered into by the Company and such successor Registrar or Paying Agent, as the case may be, and delivered to the Trustee or (2) notification to the Trustee that the Trustee shall serve as Registrar or Paying Agent until the
appointment of a successor in accordance with clause (1) above. The Registrar or Paying Agent may resign at any time upon written notice; provided, however, that the Trustee may resign as Paying Agent or Registrar only if the Trustee also
resigns as Trustee in accordance with Section 7.08. 
  

	Section 2.06	Paying Agent to Hold Money in Trust. 

 Prior to 11:00 a.m., New York City time, on the Maturity Date, each Interest Payment Date, any Fundamental Change Repurchase Date and any settlement date of a Conversion Obligation, the Company shall
deposit with the Paying Agent (or if the Company or a Wholly Owned Subsidiary of the Company is acting as Paying Agent, segregate and hold in trust for the benefit of the Persons entitled thereto) a sum sufficient to pay such amounts owed on such
dates. The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of amounts owed on
such dates and shall notify the Trustee of any Default by the Company in making any such payment. If the Company or a Wholly Owned Subsidiary of the Company acts as Paying Agent, it shall segregate the money held by it as Paying Agent and hold it as
a separate trust fund. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon complying with this Section, the Paying Agent shall have no further
liability for the money delivered to the Trustee. 
  

	Section 2.07	Holder Lists. 

 The
Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders and shall otherwise comply 

  
 15 

 
with Section 312(a) of the Trust Indenture Act. If the Trustee is not the Registrar, or to the extent otherwise required under the Trust Indenture Act, the Company shall furnish, or cause
the Registrar to furnish, to the Trustee, in writing at least five Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably
require of the names and addresses of Holders and the Company shall otherwise comply with Section 312(a) of the Trust Indenture Act. 
  

	Section 2.08	Exchange and Registration of Transfer of Notes; Restrictions on Transfer. 

 (a) The Company shall cause to be kept at the Corporate Trust Office the Register in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of
Notes and of transfers of Notes. The Register shall be in written form or in any form capable of being converted into written form within a reasonably prompt period of time. 
 Upon surrender for registration of transfer of any Notes to the Registrar or any co-registrar, and satisfaction of the requirements for such transfer set forth in this Section 2.08, the Company shall
execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denominations and of a like aggregate principal amount and bearing such restrictive legends as
may be required by this Indenture. 
 Notes may be exchanged for other Notes of any authorized denominations and of a like
aggregate principal amount, upon surrender of the Notes to be exchanged at any such office or agency maintained by the Company pursuant to Section 4.02. Whenever any Notes are so surrendered for exchange, the Company shall execute, and the
Trustee shall authenticate and deliver, the Notes that the Holder making the exchange is entitled to receive bearing registration numbers not contemporaneously outstanding. 
 All Notes issued upon any registration of transfer or exchange of Notes shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as
the Notes surrendered upon such registration of transfer or exchange. 
 All Notes presented or surrendered for registration of
transfer or for exchange, repurchase or conversion shall (if so required by the Company or the Registrar) be duly endorsed, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company, and the Notes shall
be duly executed by the Holder thereof or his attorney duly authorized in writing. 
 No service charge shall be made to any
Holder for any registration of, transfer or exchange of Notes, but the Company or the Trustee may require payment by the Holder of a sum sufficient to cover any tax, assessment or other governmental charge that may be imposed in connection with any
registration of transfer or exchange of Notes. 
 Neither the Company nor the Trustee nor any Registrar shall be required to
exchange, issue or register a transfer of (a) any Note or portions thereof surrendered for conversion pursuant to Article 10 or (b) any Note or portions thereof tendered for repurchase (and not withdrawn) pursuant to Article 3. 

  
 16 

 (b) The following provisions shall apply only to Global Notes: 

(i) Each Global Note authenticated under this Indenture shall be registered in the name of the Depositary or a nominee
thereof and delivered to such Depositary or a nominee thereof or custodian for the Global Notes therefor, and each such Global Note shall constitute a single Note for all purposes of this Indenture. 

(ii) Notwithstanding any other provision in this Indenture, no Global Note may be exchanged in whole or in part for Notes
registered, and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary or a nominee thereof unless: 

(A) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Note
and a successor Depositary has not been appointed within 60 calendar days; 
 (B) the Depositary has ceased to
be registered as a clearing agency under the Exchange Act and a successor Depositary has not been appointed within 60 calendar days; or 
 (C) an Event of Default with respect to the Notes has occurred and is continuing and the Depositary requests that its Notes be issued in physical, certificated form. 

(iii) In addition, certificated Notes shall be issued in exchange for beneficial interests in a Global Note upon request
by or on behalf of the Depositary in accordance with customary procedures following the request of a beneficial owner seeking to enforce its rights under the Notes or this Indenture, including its rights following the occurrence of an Event of
Default. 
 (iv) Notes issued in exchange for a Global Note or for any portion of a Global Note pursuant to
clause (ii) or (iii) above shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Notes or portion thereof to be so exchanged, shall be
registered in such names and be in such authorized denominations as the Depositary shall designate and shall bear any legends required hereunder. Any Global Notes to be exchanged shall be surrendered by the Depositary to the Trustee, as Registrar;
provided that pending completion of the exchange of a Global Note, the Trustee acting as custodian for the Global Notes for the Depositary or its nominee with respect to such Global Notes, shall reduce the principal amount thereof, by an
amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the books and records of the Trustee. Upon any such surrender or adjustment, the Trustee shall authenticate and make available for delivery the
Notes issuable on such exchange to or upon the written order of the Depositary or an authorized representative thereof. 

  
 17 

 (v) In the event of the occurrence of any of the events specified in clause
(ii) above or upon any request described in clause (iii) above, the Company shall promptly make available to the Trustee a sufficient supply of certificated Notes in definitive, fully registered form, without interest coupons. 

(vi) Neither any members of, or participants in, the Depositary (the “Agent Members”) nor any other
Persons on whose behalf Agent Members may act shall have any rights under this Indenture with respect to any Global Notes registered in the name of the Depositary or any nominee thereof, and the Depositary or such nominee, as the case may be, may be
treated by the Company, the Trustee and any agent of the Company or the Trustee as the absolute owner and holder of such Global Notes for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee
or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or such nominee, as the case may be, or impair, as between the Depositary, its Agent Members and any
other Person on whose behalf an Agent Member may act, the operation of customary practices of such Persons governing the exercise of the rights of a Holder of any Notes. 

(vii) At such time as all interests in a Global Note have been repurchased, converted, cancelled or exchanged for Notes in
certificated form, such Global Note shall, upon receipt thereof, be canceled by the Trustee in accordance with standing procedures and instructions existing between the Depositary and the custodian for the Global Note. At any time prior to such
cancellation, if any interest in a Global Note is repurchased, converted, cancelled or exchanged for Notes in certificated form, the principal amount of such Global Note shall, in accordance with the standing procedures and instructions existing
between the Depositary and the custodian for the Global Note, be appropriately reduced, and an endorsement shall be made on such Global Note, by the Trustee or the custodian for the Global Note, at the direction of the Trustee, to reflect such
reduction. 
 (c) Every Note (and all securities issued in exchange therefor or in substitution thereof) that bears or is
required under this Section 2.08(c) to bear the Restricted Note Legend (together with any Common Stock issued upon conversion of the Notes and required to bear the Restricted Common Stock Legend, collectively, the “Restricted
Securities”) shall be subject to the restrictions on transfer set forth in this Section 2.08(c) (including those set forth in the Restricted Note Legend and the Restricted Common Stock Legend) unless such restrictions on transfer shall
be waived by written consent of the Company following receipt of legal advice supporting the permissibility of the waiver of such transfer restrictions, and the holder of each such Restricted Security, by such holder’s acceptance thereof,
agrees to be bound by all such restrictions on transfer. As used in this Section 2.08(c), the term “transfer” means any sale, pledge, loan, transfer or other disposition whatsoever of any Restricted Security or any interest therein.

  
 18 

 (d) Until the date (the “Resale Restriction Termination Date”) that is the
later of (1) the date that is one year after the last date of the original issuance of the Notes, or such shorter period of time as permitted by Rule 144 under the Securities Act or any successor provision thereunder, and (2) such later
date, if any, as may be required by applicable laws, any certificate evidencing a Restricted Security shall bear the Restricted Note Legend (or in the case of Common Stock issued upon conversion of the Notes, the Restricted Common Stock Legend),
unless such Restricted Security has been sold pursuant to a registration statement that has been declared effective under the Securities Act (and which continues to be effective at the time of such transfer) or sold pursuant to Rule 144 under the
Securities Act or any similar provision then in force, or unless otherwise agreed by the Company in writing as set forth above, with written notice thereof to the Trustee. After the Resale Restriction Termination Date, the Restricted Note Legend
shall be deemed no longer applicable to the Notes. 
 (e) In connection with any transfer of the Notes prior to the Resale
Restriction Termination Date, the Holder must complete and deliver the form of assignment set forth on the certificate representing the Note, with the appropriate box checked, to the Trustee (or any successor Trustee, as applicable). 

Any Notes that are Restricted Securities and as to which such restrictions on transfer shall have expired in accordance with their terms
or as to conditions for removal of the Restricted Note Legend set forth therein have been satisfied may, upon surrender of such Notes for exchange to the Registrar in accordance with the provisions of this Section 2.08, be exchanged for a new
Note or Notes, of like tenor and aggregate principal amount, which shall not bear the restrictive legend required by Section 2.08(c). If such Restricted Security surrendered for exchange is represented by a Global Note bearing the Restricted
Note Legend, the principal amount of the legended Global Notes shall be reduced by the appropriate principal amount and the principal amount of a Global Note without a Restricted Note Legend shall be increased by an equal principal amount. If a
Global Note without the Restricted Note Legend is not then outstanding, the Company shall execute and the Trustee shall authenticate and deliver an unlegended Global Note to the Depositary. The Company shall notify the Trustee in writing upon the
Trustee’s request of the occurrence of the Resale Restriction Termination Date. 
 Any Common Stock issued upon conversion
of the Notes as to which such restrictions on transfer shall have expired in accordance with their terms may, upon surrender of the certificates representing such shares of Common Stock for exchange in accordance with the procedures of the transfer
agent for the Common Stock, be exchanged for a new certificate or certificates for a like aggregate number of shares of Common Stock, which shall not bear the Restricted Common Stock Legend. 

(f) The Trustee shall have no responsibility or obligation to any Agent Members or any other Person with respect to the accuracy of the
books or records, or the acts or omissions, of the Depositary or its nominee or of any participant or member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any Agent Member or other Person (other than
the Depositary) of any notice or the payment of any amount, under or with respect to such Notes. All notices and communications to be given to the Holders of Notes and all payments to be made to Holders of Notes under the Notes shall be given or
made only to 

  
 19 

 
or upon the order of the registered Holders of Notes (which shall be the Depositary or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Notes shall be
exercised only through the Depositary subject to the customary procedures of the Depositary. The Trustee may rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its Agent Members. 

(g) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer
imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Notes (including any transfers between or among Agent Members) other than to require delivery of such certificates and other documentation or
evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. 

 

	Section 2.09	Replacement Notes. 

 If a
mutilated Note is surrendered to the Registrar or if the Holder claims that the Note has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Note if the Holder takes the following
actions and satisfies the requirements of Section 8-405 of the Uniform Commercial Code: 
 (a) notifies the Company or the
Trustee within a reasonable time after he has notice of such loss, destruction or wrongful taking and prior to the Registrar registering a transfer of such Note; 
 (b) makes a request to the Company or the Trustee for a replacement Note prior to the Note being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a
“protected purchaser”); and 
 (c) satisfies any other reasonable requirements of the Company or the Trustee,
including the requirements set forth in the following paragraph. 
 If required by the Trustee or the Company, such Holder shall
furnish an indemnity bond sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, the Paying Agent and the Registrar from any loss, expense, claim or liability that any of them may suffer if a Note is replaced
and subsequently presented or claimed for payment. The Company and the Trustee may charge the Holder for their expenses in replacing a Note. In case any Note which has matured or is about to mature or has been validly tendered for repurchase on a
Fundamental Change Repurchase Date (and not validly withdrawn), or is to be converted, shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a substitute Note, pay or authorize the payment of or convert or
authorize the conversion of the same (without surrender thereof except in the case of a mutilated Note), as the case may be, if the applicant for such payment or conversion shall furnish to the Company, to the Trustee and, if applicable, to such
authenticating agent such security or indemnity as may be required by them to save each of them harmless for any loss, liability, cost or expense caused by or in connection with such substitution, and, in every case of destruction, loss or theft,
the applicant shall also 

  
 20 

 
furnish to the Company, the Trustee and, if applicable, any Paying Agent or Conversion Agent evidence to their satisfaction of the destruction, loss or theft of such Notes and of the ownership
thereof. 
 Every replacement Note is an additional obligation of the Company. 

The provisions of this Section 2.09 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, lost, destroyed or wrongfully taken Notes. 
  

	Section 2.10	Outstanding Notes. 

Notes outstanding at any time are all Notes authenticated by the Trustee except for those canceled by it, those delivered to it for
cancellation and those described in this Section as not outstanding. A Note does not cease to be outstanding because the Company or an Affiliate of the Company holds the Note. 
 If a Note is replaced pursuant to Section 2.09, it ceases to be outstanding unless the Trustee and the Company receive proof satisfactory to them that the replaced Note is held by a protected
purchaser. 
 If the Paying Agent segregates and holds in trust, in accordance with this Indenture, on a Fundamental Change
Repurchase Date or Maturity Date money sufficient to pay all principal and interest payable on that date with respect to the Notes (or portions thereof) to be repurchased or maturing, as the case may be, and the Paying Agent is not prohibited from
paying such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Notes (or portions thereof) cease to be outstanding and interest on them ceases to accrue. 

 

	Section 2.11	Temporary Notes. 

Pending the preparation of Notes in certificated form, the Company may execute and the Trustee or an authenticating agent appointed by
the Trustee shall, upon the written request of the Company, authenticate and deliver temporary Notes (printed or lithographed). Temporary Notes shall be issuable in any authorized denomination, and substantially in the form of the Notes in
certificated form, but with such omissions, insertions and variations as may be appropriate for temporary Notes, all as may be determined by the Company. Any such temporary Notes shall be executed by the Company and authenticated by the Trustee or
such authenticating agent upon the same conditions and in substantially the same manner, and with the same effect, as the Notes in certificated form. Without unreasonable delay, the Company shall execute and deliver to the Trustee or such
authenticating agent Notes in certificated form and thereupon any or all temporary Notes may be surrendered in exchange therefor, at each office or agency maintained by the Company pursuant to Section 4.02 and the Trustee or such authenticating
agent shall authenticate and make available for delivery in exchange for such temporary Notes an equal aggregate principal amount of Notes in certificated form. Such exchange shall be made by the Company at its own expense and without any charge
therefor. Until so exchanged, the 

  
 21 

 
temporary Notes shall in all respects be entitled to the same benefits and subject to the same limitations under this Indenture as Notes in certificated form authenticated and delivered
hereunder. 
  

	Section 2.12	Repurchase and Cancellation. 

 The Company may, to the extent permitted by law, repurchase any Notes in the open market or by tender offer at any price or by private agreement. Any Notes repurchased by the Company may be surrendered to
the Trustee for cancellation, but such Notes may not be reissued or resold by the Company. Any Notes surrendered for cancellation to the Trustee may not be reissued or resold and shall be promptly cancelled by the Trustee in accordance with its
standard procedures. 
  

	Section 2.13	Defaulted Interest. 

 Any
interest on any Note which is payable, but is not paid when the same becomes due and payable and such nonpayment continues for a period of 30 calendar days, shall forthwith cease to be payable to the Holder on the Regular Record Date, and such
defaulted interest and interest (to the extent lawful) on such defaulted interest at the annual rate borne by the Notes (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) shall be paid by
the Company at its election, in each case, as provided in clause (a) or (b) below: 
 (a) The Company may elect to
make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective predecessor Notes) are registered at the close of business on a Special Record Date (as defined below) for the payment of such Defaulted Interest,
which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date (not less than 30 calendar days after such notice) of the proposed
payment (the “Special Interest Payment Date”), and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided.
Thereupon the Trustee shall fix a record date (the “Special Record Date”) for the payment of such Defaulted Interest which shall be not more than fifteen calendar days and not less than ten calendar days prior to the Special
Interest Payment Date and not less than ten calendar days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date, and in the name and at the expense of the
Company, shall promptly cause notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor to be given to each Holder, not less than ten calendar days prior to such Special Record
Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date and Special Interest Payment Date therefor having been so given, such Defaulted Interest shall be paid on the Special Interest Payment Date to the Persons in
whose names the Notes (or their respective predecessor Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (b). 

  
 22 

 (b) The Company may make payment of any Defaulted Interest in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this
clause, such manner of payment shall be deemed practicable by the Trustee. 
 (c) Subject to the foregoing provisions of this
Section 2.13, each Note delivered under this Indenture upon registration of, transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other
Note. 
  

	Section 2.14	CUSIP and ISIN Numbers. 

The Company in issuing the Notes may use “CUSIP” and “ISIN” numbers (if then generally in use) and, if so, the
Trustee shall use “CUSIP” and “ISIN” numbers in notices of repurchase as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such numbers
either as printed on the Notes or as contained in any notice of a repurchase and that reliance may be placed only on the other identification numbers printed on the Notes, and any such repurchase shall not be affected by any defect in or omission of
such numbers. The Company shall promptly notify the Trustee in writing of any changes to the “CUSIP” or “ISIN” numbers of the Notes. 
 ARTICLE 3 
 REPURCHASE OF NOTES 

 

	Section 3.01	Repurchase at Option of Holders Upon a Fundamental Change. 

 (a) If a Fundamental Change occurs at any time prior to the Maturity Date, each Holder shall have the right to require the Company to repurchase all or part of such Holder’s Notes in a principal
amount thereof that is equal to $1,000 in principal amount or whole multiples thereof, on the date (the “Fundamental Change Repurchase Date”) specified by the Company in the Fundamental Change Company Notice that is not less than 20
nor more than 35 calendar days after the date of the Fundamental Change Company Notice at a repurchase price, payable in cash, equal to 100% of the principal amount of the Notes being repurchased, plus accrued and unpaid interest to, but excluding,
the Fundamental Change Repurchase Date (the “Fundamental Change Repurchase Price”). However, if such Fundamental Change Repurchase Date is after a Regular Record Date and on or prior to the corresponding Interest Payment Date, the
full amount of interest due shall be paid on the Interest Payment Date to the Holder of record on the Regular Record Date and the Fundamental Change Repurchase Price shall be equal to 100% of the principal amount of Notes to be repurchased.
Repurchases of Notes under this Section 3.01 shall be made upon: 
 (1) delivery to the Trustee or Paying
Agent by a Holder of a duly completed written notice (the “Fundamental Change Repurchase Notice”) of such Holder’s exercise of its repurchase right (together with the Notes to be repurchased, if

  
 23 

 
certificated Notes have been issued) in the form set forth on the reverse of the Note prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase
Date (the “Fundamental Change Repurchase Expiration Time”); and 
 (2) delivery or book-entry
transfer of the Notes to the Trustee or Paying Agent at any time after delivery of the Fundamental Change Repurchase Notice (together with all necessary endorsements) and prior to the Fundamental Change Repurchase Expiration Time, at the Corporate
Trust Office of the Trustee or Paying Agent, such delivery being a condition to receipt by the Holder of the Fundamental Change Repurchase Price therefor; provided, that such Fundamental Change Repurchase Price shall be so paid pursuant to
this Section 3.01 only if the Notes so delivered to the Trustee or Paying Agent shall conform in all respects to the description thereof in the related Fundamental Change Repurchase Notice. 

The Fundamental Change Repurchase Notice shall state: 

(i) with respect to Global Notes, the appropriate Depositary information and, with respect to certificated Notes, the
certificate numbers, if any, of the Notes to be tendered for repurchase; 
 (ii) the portion of the principal
amount of the Notes to be repurchased, which must be $1,000 or whole multiples thereof; and 
 (iii) that the
Notes are to be repurchased by the Company pursuant to the applicable provisions of the Notes and this Indenture. 
 Payment of
the Fundamental Change Repurchase Price for Notes for which a Fundamental Change Repurchase Notice has been delivered and not withdrawn is conditioned upon book-entry transfer or delivery of the Notes, together with necessary endorsements, to the
Trustee or Paying Agent, as the case may be. Payment of the Fundamental Change Repurchase Price for the Notes shall be made on the later of the Fundamental Change Repurchase Date and the time of book-entry transfer or delivery of the Notes, as the
case may be. 
 All questions as to the validity, eligibility (including time of receipt) and acceptance of any Notes for
repurchase shall be determined by the Company, whose determination shall be final and binding absent manifest error. 

Notwithstanding anything herein to the contrary, any Holder delivering to the Trustee or Paying Agent the Fundamental Change Repurchase
Notice contemplated by this Section 3.01 shall have the right to withdraw such Fundamental Change Repurchase Notice at any time prior to the Fundamental Change Repurchase Expiration Time by delivering a written notice of withdrawal to the
Trustee or Paying Agent in accordance with Section 3.02 below. 
 The Trustee or Paying Agent shall promptly notify the
Company of the receipt by it of any Fundamental Change Repurchase Notice or written notice of withdrawal thereof. 

  
 24 

 (b) On or before the 10th calendar day after the occurrence of a Fundamental Change, the
Company shall provide to all Holders of record on the date of the Fundamental Change at their addresses shown in the Register of the Registrar, the Trustee and the Paying Agent, a written notice (the “Fundamental Change Company
Notice”) of the occurrence of the Fundamental Change and the resulting repurchase right. Each Fundamental Change Company Notice shall specify, among other things: 

(i) the events causing the Fundamental Change; 

(ii) the date of the Fundamental Change; 

(iii) the Fundamental Change Repurchase Date; 

(iv) the last date on which a repurchase upon a Fundamental Change may be exercised, which shall be the Business Day
immediately preceding the Fundamental Change Repurchase Date; 
 (v) the Fundamental Change Repurchase Price;

 (vi) the names and addresses of the Paying Agent and the Conversion Agent; 

(vii) the procedures that a Holder must follow to exercise the right to repurchase upon a Fundamental Change; 

(viii) that the Fundamental Change Repurchase Price for any Notes as to which a Fundamental Change Repurchase Notice has
been given and not withdrawn shall be paid on the later of such Fundamental Change Repurchase Date and the time of book-entry transfer or delivery of the Notes (together with all necessary endorsements); 

(ix) that, except as otherwise provided herein with respect to a Fundamental Change Repurchase Date that is after a
Regular Record Date for the payment of an installment of interest and on or before the related Interest Payment Date, on and after such Fundamental Change Repurchase Date (unless there shall be a Default in the payment of the Fundamental Change
Repurchase Price), interest on Notes subject to repurchase upon Fundamental Change shall cease to accrue, and all rights of the Holders of such Notes shall terminate, other than the right to receive, in accordance herewith, the Fundamental Change
Repurchase Price; 
 (x) that a Holder shall be entitled to withdraw its election in the Fundamental Change
Repurchase Notice prior to the close of business on the Business Day immediately preceding the Fundamental Change Repurchase Date, by means of a letter or facsimile transmission (receipt of which is confirmed and promptly followed by a letter)
setting forth the name of such Holder, a statement that such Holder is withdrawing its election to have Notes purchased by the Company on such Fundamental Change Repurchase Date pursuant to a repurchase

  
 25 

 
upon a Fundamental Change, the certificate number(s) of such Notes to be so withdrawn, if such Notes are certificated Notes, the principal amount of the Notes of such Holder to be so withdrawn,
which amount must be $1,000 or an integral multiple thereof and the principal amount, if any, of the Notes of such Holder that remain subject to the Fundamental Change Repurchase Notice delivered by such Holder in accordance with this
Section 3.01, which amount must be $1,000 or an integral multiple thereof; 
 (xi) the Conversion Rate and
any adjustments to the Conversion Rate that shall result from such Fundamental Change; 
 (xii) that Notes with
respect to which a Fundamental Change Repurchase Notice is given by a Holder may be converted pursuant to Article 10 only if such Fundamental Change Repurchase Notice has been withdrawn in accordance with this Section 3.01 or the Company
defaults in the payment of the Fundamental Change Repurchase Price; and 
 (xiii) the CUSIP number or numbers,
as the case may be, of the Notes. 
 No failure of the Company to give the foregoing notices and no defect therein shall limit the repurchase
rights of Holders or affect the validity of the proceedings for the repurchase of the Notes pursuant to this Section 3.01. 

(c) Notwithstanding the foregoing, no Notes may be repurchased by the Company at the option of the Holders upon a Fundamental Change if
the principal amount of the Notes has been accelerated, and such acceleration has not been rescinded, on or prior to the Fundamental Change Repurchase Date (except in the case of an acceleration resulting from a Default by the Company in the payment
of the Fundamental Change Repurchase Price with respect to such Notes). 
  

	Section 3.02	Withdrawal of Fundamental Change Repurchase Notice. 

 A Fundamental Change Repurchase Notice may be withdrawn by means of a written notice of withdrawal delivered to the Trustee or Paying Agent prior to the Fundamental Change Repurchase Expiration Time. The

certificated Notes, the certificate number, if any, of the withdrawn Notes;

 Prior to 11:00 a.m., New York City time, on the Fundamental Change Repurchase Date, the Company shall deposit with the Paying Agent or, if the Company or a Wholly Owned Subsidiary of the Company is acting
as the Paying Agent, shall segregate and hold in trust as provided in Section 2.06, an amount of cash in immediately available funds, sufficient to pay the aggregate Fundamental Change Repurchase Price of all the Notes or portions thereof that
are to be repurchased as of the Fundamental Change Repurchase Date. 
 If the Trustee or Paying Agent holds on the Fundamental
Change Repurchase Date cash sufficient to pay the Fundamental Change Repurchase Price of the Notes that Holders have elected to require the Company to repurchase in accordance with Section 3.01, then, as of the Fundamental Change Repurchase
Date: 
 (i) such Notes shall cease to be outstanding and interest shall cease to accrue, whether or not
book-entry transfer of the Notes has been made or the Notes have been delivered to the Paying Agent, as the case may be; and 
 (ii) all other rights of the Holders of such Notes shall terminate, other than the right to receive the Fundamental Change Repurchase Price upon delivery or transfer of such Notes. 

 

	Section 3.04	Notes Repurchased in Part. 

 Upon presentation of any Notes repurchased only in part, the Company shall execute and the Trustee shall authenticate and make available for delivery to the Holder thereof, at the expense of the Company,

 The
Company shall promptly pay the principal of and interest on the Notes on the dates and in the manner provided in the Notes and in this Indenture. Principal and interest shall 

  
 27 

 
be considered paid on the date due if on such date the Trustee or the Paying Agent holds in accordance with this Indenture money sufficient to pay all principal and interest then due and the
Trustee or the Paying Agent, as the case may be, is not prohibited from paying such money to the Holders on that date pursuant to the terms of this Indenture. 
 The Company shall pay interest on overdue principal at the rate specified therefor in the Notes, and, to the extent lawful, it shall pay interest on overdue installments of interest at the rate and in the
manner specified in Section 2.13. 
  

	Section 4.02	Maintenance of Office or Agency. 

 The Company shall maintain an office or agency where the Notes may be surrendered for registration of transfer or exchange or for presentation for payment or for conversion or repurchase and where notices

designate from time to time by notice to the Company. The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency not designated or appointed by the Trustee. If at any time

with the SEC through its EDGAR database within the time periods for filing the same under the Exchange Act (taking into account any applicable grace periods provided thereunder) shall satisfy the Company’s obligation to furnish such reports to
the Trustee. The Company shall promptly notify the Trustee in writing if the Company fails to file any such reports. In the absence of such notification, the Trustee shall be entitled to presume that such filings were made. 

(b) The Company shall, so long as any of the Notes or any shares of Common Stock issuable upon conversion thereof will, at such time,
constitute “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, promptly provide to the Trustee and the Company shall, upon written request, provide to any Holder, beneficial owner or prospective

purchaser of such Notes or any shares of Common Stock issuable upon conversion of such Notes the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act to
facilitate the resale of such Notes or shares of Common Stock pursuant to Rule 144A under the Securities Act (“Rule 144A”). 
 (c) Delivery of such reports, information and documents to the Trustee is for information purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). The Trustee
is under no duty to examine such reports, information or documents to ensure compliance with the provisions of this Indenture or to ascertain the correctness or otherwise of the information or the statements contained therein. The Trustee is
entitled to assume such compliance and correctness unless a Responsible Officer of the Trustee is informed otherwise.

The Company shall deliver to the Trustee within 120 calendar days after the end of each fiscal year of the Company an Officers’
Certificate, stating whether or not, to the knowledge of each such Officer, any Default or Event of Default occurred during such period and if so, describing each Default or Event of Default, its status and the action the Company is taking or

 The Company shall deliver notice to the Trustee, promptly upon becoming aware of the occurrence of any Event of Default or Default, an Officers’ Certificate setting forth the details of such Event of
Default or Default, its status and the action that the Company proposes to take with respect thereto. 
  

	Section 4.09	Waiver of Stay, Extension or Usury Laws. 

 The Company covenants (to the extent it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take benefit or advantage of, any stay, extension or
usury law or other law which would prohibit or forgive the Company from paying all or any portion of the principal of or interest on the Notes as contemplated herein, wherever enacted, now or at any time; the Company (to the extent it may lawfully
do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the

or the Notes are not otherwise freely tradable by Holders other than the Company’s Affiliates or Persons that were Affiliates of the Company during the immediately preceding three months as a result of restrictions pursuant to U.S. securities
law or the terms of this Indenture or the Notes, the Company shall pay additional interest on the Notes at the rate of 0.50% per annum of the principal amount of Notes outstanding for each day during such period for which the Company’s
failure to file has occurred and is continuing. 
 (b) If, and for so long as, the Restricted Note Legend on the Notes has not
been removed or otherwise become inapplicable pursuant to Section 2.08(d) or the Notes are not freely tradable by Holders other than the Company’s Affiliates or Persons that were Affiliates of the Company during the immediately preceding
three months (without restrictions pursuant to U.S. securities law or the terms of this Indenture or the Notes), in each case as of the 366th day after the last date of original issuance of the Notes, the Company shall pay additional interest on the
Notes at a rate equal to 0.50% per annum of the principal amount of Notes outstanding until the Notes are so freely tradable.

reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

 The term “Bankruptcy Law” means Title 11, United States Code, or any similar federal or state
law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or similar official under any Bankruptcy Law. 

 

	Section 6.02	Acceleration. 

 If an
Event of Default specified in Section 6.01(k) or (l) with respect to the Company occurs, the principal amount of the Notes and accrued and unpaid interest on the outstanding Notes shall automatically become due and payable without any
declaration or other act on the part of the Trustee or any Holders. If an Event of Default (other than an Event of Default specified in Section 6.01(k) or (l) with respect to the Company) occurs and is continuing, the Trustee by notice to
the Company, or the Holders of at least 25% in aggregate principal amount of the outstanding Notes by notice to the Company and the Trustee, may declare the principal amount of the Notes and accrued and unpaid interest on the outstanding Notes to be
due and payable. Thereupon, the Trustee may, in its discretion, proceed to protect and enforce the rights of Holders by appropriate judicial proceedings. 
 After a declaration of acceleration, but before a judgment or decree for payment of the money due has been obtained by the Trustee, the Holders of a majority in aggregate principal amount of the Notes
outstanding, by written notice to the Company and the Trustee, may rescind and annul such declaration if: 
 (a) the Company or,
if applicable, any Subsidiary Guarantor has paid (or deposited with the Trustee a sum sufficient to pay): 
 (1)
all overdue interest on all Notes; 
 (2) the principal amount of any Notes that have become due otherwise than
by such declaration of acceleration; 
 (3) to the extent that payment of such interest is lawful, interest upon
overdue interest; and 
 (4) all sums paid or advanced by the Trustee under this Indenture and the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and 

  
 34 

 (b) all Events of Default, other than the non-payment of the principal amount of the Notes
and any accrued and unpaid interest that have become due solely by such declaration of acceleration, have been cured or waived. 

No such rescission and annulment shall affect any subsequent Default or Event of Default or impair any right consequent thereon.

  

	Section 6.03	Other Remedies. 

 If an
Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 

The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A
delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any
other remedy. All available remedies are cumulative. 
  

	Section 6.04	Waiver of Past Defaults. 

The Holders of a majority in aggregate principal amount of the Notes outstanding may, on behalf of all Holders, waive any past Default or
Event of Default under this Indenture and its consequences, except: 
 (a) the Company’s failure to pay principal of or
interest on any Notes when due; 
 (b) the Company’s failure to convert any Notes into cash, shares of Common Stock or a
combination of cash and shares of Common Stock, as the case may be, pursuant to the terms of this Indenture; 
 (c) the
Company’s failure to pay the Fundamental Change Repurchase Price on the Fundamental Change Repurchase Date in connection with a Holder exercising its repurchase rights; or 

(d) the Company’s failure to comply with any of the provisions of this Indenture that under Section 9.02 cannot be amended
without the consent of each Holder affected. 
 When a Default is waived, it is deemed cured, but no such waiver shall extend to
any subsequent or other Default or impair any consequent right. 
  

	Section 6.05	Control by Majority. 

The Holders of a majority in aggregate principal amount of the outstanding Notes shall have the right to direct the time, method and
place of any proceedings for any remedy 

  
 35 

 
available to the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee determines is unduly
prejudicial to the rights of other Holders or would involve the Trustee in personal liability or expense for which the Trustee has not received adequate indemnity as determined by it in good faith; provided, however, that the Trustee may take
any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall be entitled to indemnity or security reasonably satisfactory to it in its sole discretion against all
losses, liabilities, and expenses caused by taking or not taking such action. 
  

	Section 6.06	Limitation on Suits. 

 No
Holder may pursue any remedy under this Indenture, except in the case of a default in the payment of principal or interest on the Notes, unless: 
 (a) such Holder has given the Trustee written notice of an Event of Default; 
 (b)
the Holders of at least 25% in aggregate principal amount of the outstanding Notes have made a written request to the Trustee to pursue the remedy, and offered reasonable security or indemnity against any cost, liability or expense of the Trustee;

 (c) the Trustee fails to comply with such request within 60 calendar days after receipt of such request and the offer of
indemnity; and 
 (d) the Trustee has not received an inconsistent direction from the Holders of a majority in aggregate
principal amount of the outstanding Notes. 
 A Holder may not use this Indenture to prejudice the rights of another Holder or
to obtain a preference or priority over another Holder (it being understood that the Trustee shall not have any affirmative duty to ascertain whether or not such actions or forbearances are unduly prejudicial to such Holders). 

 

	Section 6.07	Rights of Holders to Receive Payment. 

 Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal (including payments pursuant to the required repurchase provisions of the Notes) of and
interest on the Notes held by such Holder, on or after the respective due dates expressed in the Notes or in the event of repurchase, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired
or affected without the consent of such Holder. In addition, notwithstanding any other provision of this Indenture, the right of any Holder to enforce its rights of conversion in accordance with the provisions of Article 10, on or after the
applicable date for settlement of the Company’s Conversion Obligation, shall not be impaired or affected without the consent of such Holder. 
  

	Section 6.08	Collection Suit by Trustee. 

 If an Event of Default specified in Section 6.01(a), (b) or (c) occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust

  
 36 

 
against the Company or, if applicable, any Subsidiary Guarantor for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts
provided for in Section 7.07. 
  

	Section 6.09	Trustee May File Proofs of Claim. 

 The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and its counsel) and the Holders allowed in any judicial proceedings relative to the Company, its Subsidiaries, any Subsidiary Guarantor or their respective creditors or property and,
unless prohibited by law or applicable regulations, may be entitled and empowered to participate as a member of any official committee of creditors appointed in such matter, and may vote on behalf of the Holders in any election of a trustee in
bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and its counsel, and any other amounts due the Trustee under
Section 7.07. 
  

	Section 6.10	Priorities. 

 If the
Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order: 
 FIRST: to the Trustee for amounts due under Section 7.07; 
 SECOND: to
Holders for amounts due and unpaid on the Notes for principal (including payments pursuant to the required repurchase provisions of the Notes) and interest, ratably without preference or priority of any kind, according to the amounts due and payable
on the Notes for principal (including payments pursuant to the required repurchase provisions of the Notes) and interest or in respect of any Conversion Obligation of the Company, respectively; and 

THIRD: to the Company. 
 The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. At least fifteen calendar days before such record date, the Trustee shall mail to each
Holder and the Company a notice that states the record date, the payment date and amount to be paid. 
  

	Section 6.11	Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or
omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable
attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits 

  
 37 

 
and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 or a suit by
Holders of more than 10% in principal amount of the Notes. 
  

	Section 6.12	Failure to Comply with Reporting Covenant. 

 Notwithstanding anything to the contrary in this Indenture, if the Company so elects, the sole remedy for an Event of Default relating to the failure to comply with the reporting obligations in described
in Section 4.03 hereof, shall, at the Company’s option, for the 90 calendar days after the occurrence of such an Event of Default, consist exclusively of the right to receive Additional Interest on the Notes at an annual rate equal to
0.50% of the principal amount of the Notes (“Reporting Additional Interest”). In the event the Company does not elect to pay the Reporting Additional Interest upon an Event of Default in accordance with this Section 6.12, the
Notes shall be subject to acceleration as provided in Section 6.02. This Reporting Additional Interest shall be in addition to any Rule 144 Additional Interest that may accrue as a result of a registration default as described under
Section 4.10 hereof and will be payable in the same manner as Rule 144 Additional Interest accruing as a result of such a registration default. Reporting Additional Interest shall accrue on all outstanding Notes from and including the date on
which an Event of Default relating to a failure to comply with the reporting obligations in this Indenture first occurs to, but not including, the 90th day (or such earlier date on which the Event of Default is cured or waived). On such 90th day if such Event of Default is continuing, such Reporting
Additional Interest will cease to accrue and the Notes will be subject to acceleration as provided in Section 6.02 above. This Section 6.12 will not affect the rights of Holders in the event of the occurrence of any other Event of Default.

 ARTICLE 7 
 TRUSTEE 
  

	Section 7.01	Duties of Trustee. 

 (a)
If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the
circumstances in the conduct of such person’s own affairs. 
 (b) Except during the continuance of an Event of Default:

 (1) the Trustee need only perform such duties as are specifically set forth in this Indenture and no implied
covenants or obligations shall be read into this Indenture against the Trustee; and

faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this

 38 

 
opinions to determine whether or not they conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated
therein).

or its own willful misconduct, except that: 
 (1) this paragraph does not limit the effect of paragraph

 (2) the Trustee shall not be liable for any error of judgment made in good faith by
a Responsible Officer unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (3) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05.

incur financial liability in the performance of any of its duties hereunder or in the exercise of any of its rights or powers, if it shall have reasonable grounds to believe that repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured to it. 
 (h) Every provision of this Indenture relating to the conduct or affecting the
liability of or affording protection to the Trustee shall be subject to the provisions of this Section and to the provisions of the Trust Indenture Act. 
  

	Section 7.02	Rights of Trustee. 

 (a)
The Trustee may rely on any document believed by it to be genuine and to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document. 

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel. The Trustee
shall not be liable for any action it takes or omits to take in good faith in reliance on the Officers’ Certificate or Opinion of Counsel. 

  
 39 

 (c) The Trustee may act through agents and shall not be responsible for the misconduct or
negligence of any agent appointed with due care.

 (e) The Trustee shall not be bound to make any investigation into the facts or
matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, note or other paper or document, but the Trustee, in its discretion, may make such further inquiry or
investigation into such facts or matters as it may see fit. 
 (f) The Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against
the costs, expenses and liabilities which may be incurred therein or thereby. 
 (g) The rights, privileges, protections,
immunities and benefits given to the Trustee, including, without limitation, its rights to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and other Person
employed to act hereunder. 
 (h) The Trustee may request that the Company and each Subsidiary Guarantor deliver an
Officers’ Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officers’ Certificate may be signed by any person authorized to sign
an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

sufficiently evidenced by an Officers’ Certificate (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be evidenced to the Trustee by copies thereof certified by the
Secretary or an Assistant Secretary (or equivalent Officer). 
 (m) The permissive rights of the Trustee set forth in this
Indenture shall not be construed as duties. 
  

	Section 7.03	Individual Rights of Trustee. 

 The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Company, any Subsidiary Guarantor or their respective Affiliates with the same
rights it would have if it were not Trustee. Any Conversion Agent, Paying Agent, Registrar or co-paying agent may do the same with like rights. However, the Trustee must comply with Sections 7.10 and 7.11. 

 

	Section 7.04	Trustee’s Disclaimer. 

 The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes or any Subsidiary Guarantee, it shall not be accountable for the
Company’s use of the proceeds from the Notes, and it shall not be responsible for any statement of the Company or any Subsidiary Guarantor in this Indenture or in any document issued in connection with the sale of the Notes or in the Notes
other than the Trustee’s certificate of authentication. 
  

	Section 7.05	Notice of Defaults. 

 (a)
The Trustee shall not be deemed to have notice of any Default or Event of Default, unless a Responsible Officer has received written notice thereof at its Corporate Trust Office, and such notice references this Indenture. No duty imposed upon the
Trustee in this Indenture shall be applicable with respect to any Default or Event of Default of which the Trustee is not deemed to have notice. 
 (b) If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail by first class mail to each Holder at the address set forth in the Register notice
of the Default or Event of Default within 90 calendar days after it becomes aware of the occurrence of such Default or Event of Default. Except in the case of a Default or Event of Default in payment of principal or interest on any Notes or a
Default in the failure to deliver the consideration due upon conversion, the Trustee may withhold notice if and so long as a committee of its Responsible Officers in good faith determines that withholding notice is in the interests of the Holders.

  

	Section 7.06	Reports by Trustee to Holders. 

 Within 60 calendar days after each May 15 beginning with the May 15 following the date of this Indenture, the Trustee shall mail to each Holder a brief report dated as of such

  
 41 

 
May 15 that complies with Section 313(a) of the Trust Indenture Act, if required by such Section 313(a) of the Trust Indenture Act. The Trustee also shall comply with
Section 313(b) of the Trust Indenture Act. The Trustee shall also transmit by mail all reports required by Section 313(c) of the Trust Indenture Act. 
  

	Section 7.07	Compensation and Indemnity. 

 The Company shall pay to the Trustee from time to time such compensation as the Company and the Trustee shall from time to time agree in writing. The Trustee’s compensation shall not be limited by
any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its
services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents, counsel, accountants and experts. Each of the Company and any Subsidiary Guarantor, jointly and severally, shall
indemnify the Trustee, and hold it harmless, against any and all loss, liability or expense (including reasonable attorneys’ fees) incurred by or in connection with the offer and sale of the Notes or the acceptance or administration of this
trust and the performance of its duties or powers hereunder. The Trustee shall notify the Company of any claim for which it may seek indemnity promptly upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the
Company shall not relieve the Company of its indemnity obligations hereunder. The Company shall defend the claim and the indemnified party shall provide reasonable cooperation at the Company’s expense in the defense. Such indemnified parties
may have separate counsel and the Company shall pay the fees and expenses of such counsel; provided, however, that the Company shall not be required to pay such fees and expenses if it assumes such indemnified parties’ defense and, in
such indemnified parties’ reasonable judgment, there is no conflict of interest between the Company and such parties in connection with such defense. Notwithstanding any of the foregoing, the Company need not reimburse any expense or indemnify
against any loss, liability or expense incurred by an indemnified party through such party’s own willful misconduct and negligence. 
 To secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a lien prior to the Notes on all money or property held or collected by the Trustee other than money or
property held in trust to pay principal of and interest and any liquidated damages on particular Notes. 
 The obligations of
the Company and the Subsidiary Guarantors pursuant to this Section 7.07 shall survive the satisfaction or discharge of this Indenture, any rejection or termination of this Indenture under any bankruptcy law or the resignation or removal of the
Trustee. When the Trustee incurs expenses after the occurrence of an Event of Default specified in Section 6.01(k) or (l) with respect to the Company the expenses are intended to constitute expenses of administration under the Bankruptcy
Law. 

  
 42 

	Section 7.08	Replacement of Trustee. 

The Trustee may resign at any time by so notifying the Company. The Holders of a majority in principal amount of the Notes may remove the
Trustee by so notifying the Trustee and may appoint a successor Trustee. The Company shall remove the Trustee if: 
 (a) the
Trustee fails to comply with Section 7.10; 
 (b) the Trustee is adjudged bankrupt or insolvent; 

(c) a receiver or other public officer takes charge of the Trustee or its property; or 

(d) the Trustee otherwise becomes incapable of acting. 
 If the Trustee is removed by the Holders of a majority in principal amount of the Notes and such Holders do not reasonably promptly appoint a successor Trustee, or if the Trustee resigns, is removed by
the Company or a vacancy otherwise exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Company shall promptly appoint a successor Trustee. 

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the
resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to
Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.07. 
 If a successor Trustee does not take office within 60 calendar days after the retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in principal amount of the Notes may
petition any court of competent jurisdiction (at the expense of the Company) for the appointment of a successor Trustee. 
 If
the Trustee fails to comply with Section 7.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

Notwithstanding the replacement of the Trustee pursuant to this Section, the Company’s and the Subsidiary Guarantors’
obligations under Section 7.07 shall continue for the benefit of the retiring Trustee. 
  

	Section 7.09	Successor Trustee by Merger. 

 If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business or assets to, another corporation or banking association, the resulting,
surviving or transferee corporation without any further act shall be the successor Trustee. 

  
 43 

 In case at the time such successor or successors by merger, conversion or consolidation to
the Trustee shall succeed to the trusts created by this Indenture any of the Notes shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver
such Notes so authenticated; and in case at that time any of the Notes shall not have been authenticated, any successor to the Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor to the
Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Notes or in this Indenture provided that the certificate of the Trustee shall have. 

 

	Section 7.10	Eligibility; Disqualification. 

 The Trustee shall at all times satisfy the requirements of Trust Indenture Act § 310(a). The Trustee shall have a combined capital and surplus of at least $100,000,000 as set forth in its most recent
published annual report of condition. The Trustee shall comply with Trust Indenture Act § 310(b); provided, however, that there shall be excluded from the operation of Trust Indenture Act § 310(b)(1) any indenture or
indentures under which other securities or certificates of interest or participation in other securities of the Company or the Subsidiary Guarantors are outstanding if the requirements for such exclusion set forth in Trust Indenture Act §
310(b)(1) are met. 
  

	Section 7.11	Preferential Collection of Claims Against Company. 

 The Trustee shall comply with Trust Indenture Act § 311(a), excluding any creditor relationship listed in Trust Indenture Act § 311(b). A Trustee who has resigned or been removed shall be
subject to Trust Indenture Act § 311(a) to the extent indicated. 
 ARTICLE 8 

DISCHARGE OF INDENTURE 
  

	Section 8.01	Discharge of Liability on Notes. 

 (a) This Indenture shall, subject to Section 8.01(b), cease to be of further effect if: 
 (1) the Company (i) delivers all outstanding Notes (other than Notes replaced pursuant to Section 2.09) to the Trustee for cancellation or (ii) (x) deposits with the Trustee or the
Paying Agent after such Notes have become due and payable, whether at stated maturity, upon conversion, or on any Fundamental Change Repurchase Date, cash (including any cash in lieu of fractional shares in connection with the conversion) and
(y) in the case of a conversion for which a Physical Settlement or Combination Settlement applies, delivers to the converting Holders shares of Common Stock issuable upon conversion, in each case calculated in accordance with this Indenture
sufficient to satisfy all obligations due on all outstanding Notes and pays all other sums payable under this Indenture; and 

  
 44 

 (2) the Company has delivered to the Trustee an Officers’ Certificate
and an Opinion of Counsel, each stating that all conditions precedent provided herein relating to the satisfaction and discharge of this Indenture have been complied with. 
 (b) Notwithstanding Section 8.01(a), the obligations of the Company and the Guarantors, as applicable, in Sections 2.05, 2.06, 2.07, 2.08, 2.09, 2.10, 7.07, 7.08 and in this Article 8 shall survive
until the Notes have been paid in full. Thereafter, the obligations of the Company and the Guarantors, as applicable, in Sections 7.07, 8.03 and 8.04 shall survive. 
  

	Section 8.02	Application of Trust Money. 

 The Trustee shall hold in trust money or other property due in respect of converted Notes or payments due under this Article 8 deposited with it pursuant to this Article 8. It shall apply the deposited
money through the Paying Agent and in accordance with this Indenture to the payment of principal of and interest on the Notes due in respect of converted Notes, in accordance with this Indenture in relation to the conversion of Notes pursuant to the
terms hereof. 
  

	Section 8.03	Repayment to Company. 

Subject to any applicable abandoned property law, the Trustee and the Paying Agent shall pay to the Company upon written request any
money held by them for the payment of principal or interest and any shares of Common Stock or other property due in respect of converted Notes that remains unclaimed for two years, and, thereafter, Holders entitled to the money and/or securities
must look to the Company for payment as general creditors. 
  

	Section 8.04	Reinstatement. 

 If the
Trustee or Paying Agent is unable to apply any money or to deliver any other property due in respect of converted Notes or other payments due in accordance with this Article 8 by reason of any legal proceeding or by reason of any order or judgment
of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to
this Article 8 until such time as the Trustee or Paying Agent is permitted to apply all such money or other property due in respect of converted Notes or other payments due in accordance with this Article 8; provided, however, that, if the
Company has made any payment of interest on or principal of any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the
Trustee or Paying Agent. 

  
 45 

 ARTICLE 9 
 AMENDMENTS 
  

	Section 9.01	Without Consent of Holders. 

 This Indenture (including the terms and conditions of the Notes) and the Notes may be modified or amended by the Company, the Subsidiary Guarantors and the Trustee, without the consent of the Holders, to,

with a Fundamental Change and/or in the event of any events described under Section 10.05;

 (h) increase the Conversion Rate; 
 (i) reflect the release of any Subsidiary
Guarantor from its Subsidiary Guarantee of the Notes, or the addition of any Subsidiary of the Company as a Subsidiary Guarantor, in the manner provided in this Indenture, or to add any other guarantor of the Notes; and 

(j) provide for a successor Trustee. 
 After a modification or amendment under this Section 9.01 becomes effective, the Company shall provide to Holders a notice briefly describing such modification or amendment. However, the failure to
give such notice to all Holders, or any defect in the notice, shall not impair or affect the validity of the modification or amendment under this Section 9.01. 

  
 46 

	Section 9.02	With Consent of Holders. 

This Indenture (including the terms and conditions of the Notes) may not be modified or amended without the written consent or the
affirmative vote of the Holder of each Note affected by such change to: 
 (a) change the Maturity Date of any Notes;

 (b) reduce the rate or extend the time for payment of interest on any Notes; 

(c) reduce the principal amount of any Notes; 
 (d) reduce any amount payable upon repurchase of any Notes upon a Fundamental Change; 
 (e) impair the right of a Holder to receive payment with respect to any Notes or institute suit for payment of any Notes; 
 (f) change the currency in which any Note is payable; 
 (g) change the
Company’s obligation to repurchase any Notes upon a Fundamental Change in a manner adverse to the Holders; 
 (h) affect
the right of a Holder to convert any Notes into cash, shares of Common Stock or a combination of cash and shares of Common Stock, as the case may be, or reduce the number of shares of Common Stock or amount of property, including cash, receivable
upon conversion pursuant to the terms of this Indenture; or 
 (i) reduce the percentage of the Notes required for consent to
any modification or waiver of this Indenture. 
 Except as otherwise provided in this Section 9.02, this Indenture
(including the terms and conditions of the Notes) and the Notes may be modified or amended, with the consent or affirmative vote of the Holders of a majority in aggregate principal amount of the Notes then outstanding (including consents obtained in
connection with a tender offer or exchange offer). The consent of the Holders is not necessary under this Indenture to approve the particular form of any proposed modification or amendment. Any consent under this Section 9.02 is sufficient if
such consent approves the substance of the proposed modification or amendment. 
 After a modification or amendment under this
Section 9.02 becomes effective, the Company shall provide to Holders a notice briefly describing such modification or amendment. However, the failure to give such notice to all Holders, or any defect in the notice, shall not impair or affect
the validity of the modification or amendment under this Section 9.02. 

  
 47 

	Section 9.03	Compliance with Trust Indenture Act. 

 Every amendment to this Indenture or the Notes shall comply with the Trust Indenture Act as then in effect. 
  

	Section 9.04	Revocation and Effect of Consents and Waivers. 

 A consent to an amendment or a waiver by a Holder shall bind the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note,
even if notation of the consent or waiver is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Note or portion of the Note if the Trustee receives the notice of revocation
before the date the amendment or waiver becomes effective. An amendment or waiver becomes effective once both (i) the requisite number of consents have been received by the Company or the Trustee and (ii) such amendment or waiver has been
executed by the Company, the Subsidiary Guarantors and the Trustee. 
 The Company may, but shall not be obligated to, fix a
record date for the purpose of determining the Holders entitled to give their consent or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the
immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such
action, whether or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 calendar days after such record date. 

 

	Section 9.05	Notation on or Exchange of Notes. 

 If an amendment changes the terms of a Note, the Trustee may require the Holder of the Note to deliver the Note to the Trustee. The Trustee may place an appropriate notation on the Note regarding the
changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Note shall issue and the Trustee shall authenticate a new Note that reflects the changed terms. Failure to make
the appropriate notation or to issue a new Note shall not affect the validity of such amendment. 
  

	Section 9.06	Trustee to Sign Amendments. 

 The Trustee shall sign any amendment authorized pursuant to this Article 9 if the amendment does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee
may but need not sign it. In signing such amendment the Trustee shall be entitled to receive, and (subject to Sections 7.01 and 7.02) shall be fully protected in relying upon, in addition to the documents required by Section 12.04, an
Officers’ Certificate and an Opinion of Counsel stating that such amendment is authorized or permitted by this Indenture.

 ARTICLE 10 
 CONVERSION OF NOTES 
  

	Section 10.01	Right to Convert. 

 Upon
compliance with the provisions of this Article 10, a Holder may convert, at such Holder’s option, all or part of its Notes, in integral multiples of $1,000, based on the Conversion Rate (the “Conversion Obligation”). Prior to
December 1, 2016, Holders shall have the right to convert their Notes only under the circumstances described in clauses (a) through (d) below. On or after December 1, 2016, a Holder may surrender its Notes for conversion at any
time prior to the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date without regard to the conditions in clauses (a) through (d) below. In no event may Notes be surrendered for conversion after
the close of business on the second Scheduled Trading Day immediately preceding the Maturity Date. 
 (a) Conversion Based on
Common Stock Price. Notes may be surrendered for conversion on any date during any calendar quarter beginning after June 30, 2012 (and only during such calendar quarter) if the Closing Sale Price of the Common Stock was more than 130% of
the then current Conversion Price for at least 20 Trading Days in the period of the 30 consecutive Trading Days ending on the last trading day of the previous calendar quarter. 

(b) Conversion Upon Specified Corporate Transactions. If the Company: 

(1) distributes to all or substantially all holders of its Common Stock rights, options or warrants entitling them to
purchase, for a period of 45 calendar days or less from the declaration date for such distribution, shares of Common Stock at a price per share less than the average Closing Sale Price of Common Stock for the ten consecutive Trading Days immediately
preceding, but excluding, the declaration date for such distribution; or 
 (2) makes a distribution to all or
substantially all holders of its Common Stock cash, other assets, securities or rights to purchase securities of the Company (other than pursuant to a rights plan), which distribution has a per share value exceeding 10% of the Closing Sale Price of
the Common Stock on the Trading Day immediately preceding the declaration date for such distribution, 
 then, in each case, the Company shall
notify all Holders at least 30 Business Days (or 10 Business Days if the Company elects Physical Settlement for related conversions pursuant to Section 10.02(b)) prior to the Ex-Date for any such distribution. Once the Company has given such
notice, a Holder may surrender all or a portion of its Notes for conversion at any time until the earlier of the close of business on the Business Day immediately preceding the Ex- Date or the Company’s public announcement that such
distribution shall not take place. A Holder may not convert any of its Notes based on this Section 10.01(b) if as a result of holding its Notes such Holder shall otherwise participate in the distribution, without converting the Notes, at the
same time and on the same terms as holders of the Common Stock as if such Holder held a number of 

  
 49 

 
shares of Common Stock equal to the Conversion Rate on the Record Date of such distribution for each $1,000 principal amount of Notes held by such Holder (calculated on an aggregate basis per
Holder). 
 (c) Conversion Upon a Fundamental Change. If a Fundamental Change occurs, the Company shall, to the extent
practicable, notify each Holder at least 30 Business Days prior to the anticipated effective date for any such transaction. In such event, each Holder will have the right to convert its Notes at any time beginning 30 Business Days prior to the date
the Company notifies such Holder as being the anticipated effective date of the transaction until the close of business on the Business Day immediately preceding the relevant Fundamental Change Repurchase Date. If any Holder has submitted any or all
of its Notes for repurchase in connection with a Fundamental Change, unless such Holder has withdrawn such Notes in a timely fashion, its conversion rights on the Notes so subject to repurchase will expire at the close of business on the Business
Day preceding the Fundamental Change Repurchase Date, unless the Company defaults in the payment of the Fundamental Change Repurchase Price. If any Holder has submitted any Notes for repurchase, such Notes may be converted only if such Holder
properly submits a withdrawal notice and, if the Notes submitted are evidenced by a Global Note, such Holder complies with appropriate Depositary procedures. 
 (d) Conversion Upon Satisfaction of Trading Price Condition. Notes may be surrendered for conversion during the five Business Day period following any five consecutive Trading Day period in which
the Trading Price per $1,000 principal amount of Notes, as determined following a request by a Holder in accordance with the procedures set forth in this Section 10.01(d), for each Trading Day of such five Trading Day period was less than 98%
of the product of the Closing Sale Price of the Common Stock for each Trading Day during such five Trading Day period and the then current Conversion Rate. The Company shall determine the Trading Price per $1,000 principal amount of Notes. The
Company shall have no obligation to make such determination unless and until a Holder requests that the Company do so and provides reasonable evidence that the then current Trading Price of the Notes is less than the minimum Trading Price threshold.
Once a Holder makes such a request, the Company shall, within two Business Days thereafter, determine the Trading Price per $1,000 principal amount of Notes for each Trading Day until the minimum Trading Price threshold is exceeded. If the Company
does not so obtain bids when required, the Trading Price per $1,000 principal amount of Notes will be deemed to be less than 98% of the product of the Closing Sale Price of the Common Stock and the applicable Conversion Rate on each Trading Day such
failure occurs. 
  

	Section 10.02	Conversion Procedures; Settlement Upon Conversion; No Adjustment for Interest or Dividends; Cash Payments in Lieu of Fractional Shares. 

(a) In order to exercise the conversion right with respect to any Notes in certificated form, a Holder must, prior to the deadline for
such conversion specified in Section 10.01: 
 (1) complete and manually sign a notice of conversion in the
form entitled “Form of Conversion Notice” attached to the reverse of such certificated Note (or a facsimile thereof) (a “Conversion Notice”); 

  
 50 

 (2) deliver such Conversion Notice and the certificated Notes to be
converted to the Conversion Agent at the office of the Conversion Agent; 
 (3) to the extent any shares of
Common Stock issuable upon conversion are to be issued in a name other than the Holder’s, furnish appropriate endorsements and transfer documents as may be required by the Conversion Agent; 

(4) if required pursuant to this Section 10.02(a), pay funds equal to interest payable on the next Interest Payment
Date to which such Holder is not entitled; and 
 (5) if required pursuant to Section 10.02(f), pay all
transfer or similar taxes, if any. 
 In order to exercise the conversion right with respect to any interest in a Global Note, a
Holder must, prior to the deadline for such conversion specified in Section 10.01: 
 (1) deliver to the
Conversion Agent via the Depositary the appropriate instruction form for conversion pursuant to the Depositary’s conversion program; 
 (2) if required pursuant to this Section 10.02(a), pay funds equal to interest payable on the next Interest Payment Date to which such Holder is not entitled; and 

(3) if required pursuant to Section 10.02(f), pay all transfer or similar taxes, if any. 

The Business Day on which the Holder satisfies the foregoing requirements is the “Conversion Date.” The Notes shall be
deemed to have been converted immediately prior to the close of business on the Conversion Date; provided, however, that the Person in whose name any shares of the Common Stock shall be issuable upon such conversion shall become the holder of
record of such shares as of the close of business on the Conversion Date, in the case of Physical Settlement, or the last Trading Day of the relevant Conversion Period, in the case of Combination Settlement. 

If a Holder converts any Notes after the close of business on the Regular Record Date for an interest payment but prior to the
corresponding Interest Payment Date, the record Holder on such Regular Record Date shall receive on the corresponding Interest Payment Date the full amount of interest accrued and unpaid on such Notes, notwithstanding such Holder’s conversion
of those Notes prior to the Interest Payment Date. However, except as provided in the next sentence, at the time such Holder surrenders its Notes for conversion after the close of business on a Regular Record Date but prior to the open of business
on the corresponding Interest Payment Date, such Holder must pay the Company an amount equal to the interest that has accrued and shall be paid on the Notes being converted on the corresponding Interest Payment Date. Such Holder is not required to
make such payment: 
 (1) if such Holder converts its Notes following the close of business on the Regular Record
Date immediately preceding the Maturity Date; 

  
 51 

 (2) if such Holder converts its Notes in connection with a Fundamental
Change and the Company has specified a Fundamental Change Repurchase Date that is after a Regular Record Date and on or prior to the corresponding Interest Payment Date; or 

(3) to the extent of any overdue interest, if overdue interest exists at the time of conversion with respect to such
Holder’s Notes. 
 If a Holder has already delivered a Fundamental Change Repurchase Notice pursuant to Section 3.01
with respect to a Note, such Holder may not surrender that Note for conversion until such Holder has validly withdrawn the Fundamental Change Repurchase Notice in accordance with Section 3.02, except as to a portion of such Note that is not
subject to such Fundamental Change Repurchase Notice. 
 (b) Subject to this Section 10.02, Section 10.03,
Section 10.04(f) and Section 10.05, upon conversion of any Note, the Company may, at its election, pay or deliver, as the case may be, to the converting Holder, in respect of each $1,000 principal amount of Notes being converted either
solely cash (“Cash Settlement”), solely shares of Common Stock (other than cash in lieu of any fractional shares) (“Physical Settlement”) or a combination of cash and shares of Common Stock (“Combination
Settlement”), as set forth in this Section 10.02(b). 
 All conversions occurring on or after December 1,
2016 shall be settled using the same Settlement Method. Prior to December 1, 2016, the Company shall use the same Settlement Method for all conversions occurring on the same Conversion Date, but the Company shall not have any obligation to use
the same Settlement Method with respect to conversions that occur on different Conversion Dates. If the Company elects a Settlement Method, the Company shall inform Holders so converting (the “Settlement Notice”) of such Settlement
Method through the Trustee, no later than the close of business on the Scheduled Trading Day immediately following the related Conversion Date (or, in the case of any conversions occurring on or after December 1, 2016, no later than the close
of business on the Scheduled Trading Day immediately preceding December 1, 2016). If the Company does not timely elect a Settlement Method, the Company shall no longer have the right to elect Cash Settlement or Physical Settlement, and the
Company shall be deemed to have elected Combination Settlement in respect of its Conversion Obligation, and the Specified Dollar Amount per $1,000 principal amount of Notes shall be deemed to be $1,000. If the Company elects Combination Settlement
but does not timely notify converting Holders of the Specified Dollar Amount per $1,000 principal amount of Notes, such Specified Dollar Amount will be deemed to be $1,000. 
 The cash, shares of Common Stock or combination of cash and shares of Common Stock in respect of any conversion of Notes (the “Settlement Amount”) shall be computed as follows:

 (1) if the Company elects to satisfy its Conversion Obligation in respect of such conversion by Physical
Settlement, the Company shall deliver to converting Holders in respect of each $1,000 principal amount of Notes being converted a number of shares of Common Stock equal to the Conversion Rate in effect on the Conversion Date (and cash in lieu of any
fractional share as described in Section 10.02(i)); 

  
 52 

 (2) if the Company elects to satisfy its Conversion Obligation in respect of
such conversion by Cash Settlement, the Company shall pay to converting Holders in respect of each $1,000 principal amount of Notes being converted cash in an amount equal to the sum of the Daily Conversion Values for each of the 25 consecutive
Trading Days in the relevant Conversion Period; and 
 (3) if the Company elects (or is deemed to have elected)
to satisfy its Conversion Obligation in respect of such conversion by Combination Settlement, the Company shall pay or deliver, as the case may be, to converting Holders in respect of each $1,000 principal amount of Notes being converted, a
Settlement Amount equal to the sum of the Daily Settlement Amounts for each of the 25 consecutive Trading Days in the relevant Conversion Period (and cash in lieu of any fractional share as described in Section 10.02(i)). 

(c) Except as described under Section 10.03, Section 10.04 and Section 10.05, if Cash Settlement or Combination Settlement
is applicable, the Company shall pay and/or deliver the consideration due upon conversion on the third Business Day immediately following the final Trading Day of the related Conversion Period. If Physical Settlement is applicable, the Company shall
deliver the consideration due upon conversion on the third Business Day immediately following the related Conversion Date; provided, that, with respect to any Conversion Date with respect to which Physical Settlement applies occurring after
February 15, 2017, settlement will occur on the Maturity Date (except as otherwise provided in Section 10.04). 
 (d)
If more than one Note shall be surrendered for conversion at one time by the same Holder, the Conversion Obligation with respect to such Notes, if any, that shall be payable upon conversion shall be computed on the basis of the aggregate principal
amount of the Notes (or specified portions thereof to the extent permitted thereby) so surrendered. 
 (e) In case any
certificated Note shall be surrendered for partial conversion, the Company shall execute and the Trustee shall authenticate and deliver to or upon the written order of the Holder of the certificated Note so surrendered, without charge to such
Holder, a new certificated Note or Notes in authorized denominations in an aggregate principal amount equal to the unconverted portion of the surrendered certificated Note. 
 (f) Upon the conversion of an interest in a Global Note, the Trustee and the Depositary shall reduce the principal amount of such Global Note in their records. 

(g) The issue of stock certificates on conversions of Notes shall be made without charge to the converting Holder of Notes for any taxes
or duties in respect of the issue 

  
 53 

 
thereof. The Company shall not, however, be required to pay any such tax or duty which may be payable in respect of any transfer involved in the issue and delivery of stock in any name other than
that of the Holder of any Notes converted, and the Company shall not be required to issue or deliver any such stock certificate unless and until the Person or Persons requesting the issue thereof shall have paid to the Company the amount of such tax
or duty or shall have established to the satisfaction of the Company that such tax has been paid. 
 (h) Except as provided in
Section 10.02(a), upon conversion, Holders shall not receive any separate cash payment of accrued and unpaid interest on the Notes. Accrued and unpaid interest (excluding any Additional Interest) and accrued tax original issue discount, if any,
to the Conversion Date shall be deemed to be paid in full with the payment or delivery, as the case may be, of the cash, Common Stock or a combination thereof, upon conversion, rather than cancelled, extinguished or forfeited. With respect to any
conversion with Combination Settlement, accrued and unpaid interest will be deemed to be paid first out of the cash paid upon such conversion. 
 (i) The Company shall not issue fractional shares of Common Stock upon conversion of the Notes. If any fractional shares of Common Stock would be issuable upon the conversion of any Note or Notes, the
Company shall instead pay cash in lieu of fractional shares based on the Closing Sale Price of the Common Stock on the relevant Conversion Date, in the case of Physical Settlement, or on the final Trading Day of the relevant Conversion Period, in
the case of Combination Settlement. 
 (j) Except as described under Section 10.04, the Company shall not make any payment
or other adjustment for dividends on any Common Stock issued upon conversion of the Notes. 
 (k) The Company shall inform the
Trustee upon its request if the Notes have become convertible under Section 10.01(a). 
  

	Section 10.03	Adjustment to Conversion Rate Upon a Make-Whole Fundamental Change. 

 If and only to the extent a Holder elects to convert its Notes in connection with a Fundamental Change described in clauses (1), (2) (without giving effect to the proviso in such clause (2)) or
(4) under the definition of Fundamental Change (a “Make-Whole Fundamental Change”), the Conversion Rate shall be increased by an additional number of shares of Common Stock (the “Additional Shares”).

 The number of Additional Shares shall be determined by reference to the table below, based on the date on which the
Make-Whole Fundamental Change becomes effective (the “Effective Date”) and the price paid (or deemed paid) per share (the “Stock Price”) for the Common Stock in such Make-Whole Fundamental Change. If holders of
Common Stock receive only cash in any transaction described in clause (2) of the definition of Fundamental Change, the Stock Price will be the cash amount paid per share. Otherwise, the Stock Price will be equal to the average of the Closing
Sale Prices of the Common Stock on the five Trading Days prior to, 

  
 54 

 
but excluding, the Effective Date of such Make-Whole Fundamental Change. The Company shall notify Holders of the anticipated Effective Date of any Make-Whole Fundamental Change at least 10
Business Days prior to such anticipated Effective Date, to the extent practicable. 
 A conversion of the Notes by a Holder
shall be deemed for purposes of this Section 10.03 to be “in connection with” a Make-Whole Fundamental Change only if the Conversion Date occurs on or following the Effective Date of the Make-Whole Fundamental Change but before the
close of business on the Business Day immediately preceding the related Fundamental Change Repurchase Date (as specified in the Fundamental Change Company Notice). 
 Upon surrender of Notes for conversion in connection with a Make-Whole Fundamental Change, the Company shall, at its option, satisfy its Conversion Obligation by Physical Settlement, Cash Settlement or
Combination Settlement, as described under Section 10.02(b). However, if the consideration received by holders of the Common Stock in any Make-Whole Fundamental Change described in clause (2) of the definition of Fundamental Change is
composed entirely of cash, for any conversion of Notes following the Effective Date of such Make-Whole Fundamental Change, the Settlement Amount will be calculated based solely on the Stock Price for the transaction and will be deemed to be an
amount of cash per $1,000 principal amount of converted Notes equal to the Conversion Rate (including any adjustment as described in this Section 10.03), multiplied by such Stock Price. In such event, the Company shall satisfy its Conversion
Obligation by paying cash to converting Holders on the third Business Day immediately following the Conversion Date. 
 The
number of Additional Shares set forth in the table below shall be adjusted in the same manner as and at the same time as the Conversion Rate of the Notes is adjusted pursuant to Section 10.04. The Stock Prices set forth in the first row of the
table below (i.e., the column headers) shall be simultaneously adjusted to equal the Stock Prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which shall be the Conversion Rate immediately prior to the adjustment
and the denominator of which shall be the Conversion Rate as so adjusted. 
 The following table sets forth the number of
Additional Shares by which the Conversion Rate shall be increased upon conversion in connection with a Make-Whole Fundamental Change:

 provided, however, that the exact Stock Price and Effective Date may not be set forth on the table,
in which case, if the Stock Price is: 
 (1) between two Stock Prices on the table or the Effective Date is
between two Effective Dates on the table, the number of Additional Shares will be determined by straight-line interpolation between the number of Additional Shares set forth for the higher and lower Stock Prices and the earlier and later Effective
Dates, as applicable, based on a 360-day year; 
 (2) greater than $160.00 per share (subject to adjustment in
the same manner and at the same time as the Stock Prices in the table above), the Conversion Rate will not be increased; or 
 (3) less than $31.95 per share (subject to adjustment in the same manner and at the same time as the Stock Prices in the table above), the Conversion Rate will not be increased. 

Notwithstanding the foregoing, in no event shall the total number of shares of Common Stock issuable upon conversion exceed 31.2989
shares per $1,000 principal amount of Notes, subject to adjustment in the same manner as the Conversion Rate pursuant to Section 10.04. 
 In the event of an increase in the Conversion Rate above that which would result in the Notes, in the aggregate, becoming convertible into shares in excess of certain limitations set forth in the listing
standards of the NYSE requiring stockholder approval, the Company shall, at its option, either obtain stockholder approval of such issuances or deliver cash in lieu of any shares otherwise deliverable upon conversions in excess of such limitations
based on the Closing Sale Price of the Common Stock on the relevant Conversion Date, in the case of Physical Settlement, or on the VWAP of the Common Stock on each Trading Day of the relevant Conversion Period in respect of which, in lieu of
delivering shares of Common Stock, the Company delivers cash pursuant to this paragraph, in the case of Combination Settlement. 
  

	Section 10.04	Adjustment of Conversion Rate. 

 The Company shall adjust the Conversion Rate for the following events: 
 (a) If
the Company shall issue shares of Common Stock as a dividend or distribution on shares of Common Stock, or if the Company effects a share split or share combination with respect to its Common Stock, the Conversion Rate shall be adjusted based on the
following formula: 
  

													
		 	CR1	  	=	  	CR0	  	×	  	     OS1    
	  	
	 	  	  	  	  	OS0	  	

  
 56 

 where, 
  

					
	CR1	  	=	 	the Conversion Rate in effect immediately after the open of business on the Ex-Date for such dividend or distribution or the effective date of such share split or share combination,
as the case may be;
			
	CR0	  	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Date for such dividend or distribution or the effective date of such share split or share
combination, as the case may be;
			
	OS0	  	=	 	the number of shares of Common Stock outstanding immediately prior to the open of business on the Ex-Date for such dividend or distribution or the effective date of such share split
or share combination, as the case may be;
			
	OS1	  	=	 	the number of shares of Common Stock that would be outstanding immediately after, and solely as a result of, such dividend, distribution, share split or share combination, as the
case may be.

 Any adjustment made under this clause (a) shall become effective immediately after the open of
business on such Ex-Date for such dividend or distribution, or immediately after the open of business on the effective date for such share split or share combination, as applicable. If any dividend or distribution of the type described in this
clause (a) is declared but not so paid or made, the Conversion Rate shall be immediately readjusted, effective as of the date the Board of Directors or a committee thereof determines not to pay such dividend or distribution, to the Conversion
Rate that would then be in effect if such dividend or distribution had not been declared. 
 (b) If the Company shall distribute
to all or substantially all holders of its Common Stock any rights, options or warrants entitling them to purchase, for a period of 45 calendar days or less from the declaration date for such distribution, shares of the Common Stock at a price per
share less than the average Closing Sale Price of the Common Stock for the ten consecutive Trading Days immediately preceding, but excluding, the declaration date for such distribution, the Conversion Rate shall be increased based on the following
formula: 
  

													
		 	CR1	  	=	  	CR0	  	×	  	     OS0 + X    
	  	
	 	  	  	  	  	OS0 + Y	  	

 where 
  

					
	CR1	  	=	 	the Conversion Rate in effect immediately after the open of business on the Ex-Date for such distribution;

  
 57 

					
	CR0	  	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Date for such distribution;
			
	OS0	  	=	 	the number of shares of the Common Stock outstanding immediately prior to the open of business on the Ex-Date for such distribution;
			
	X	  	=	 	the total number of shares of the Common Stock issuable pursuant to such rights, options or warrants; and
			
	Y	  	=	 	the number of shares of the Common Stock equal to the aggregate price payable to exercise such rights, options or warrants, divided by the average Closing Sale Price of the
Common Stock for the ten consecutive Trading Days immediately preceding, but excluding, the declaration date for such distribution.

 Any increase made under this clause (b) shall be made successively whenever any such rights, options
or warrants are distributed and shall become effective immediately after the open of business on the Ex-Date for such distribution. To the extent that shares of the Common Stock are not delivered after the expiration of such rights, options or
warrants, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect had the increase with respect to the distribution of such rights, options or warrants been made on the basis of delivery of only the number of
shares of the Common Stock actually delivered. If such rights, options or warrants are not so distributed, the Conversion Rate shall be decreased to the Conversion Rate that would then be in effect if such Ex-Date for such distribution had not
occurred. 
 For purposes of this clause (b) and Section 10.01(b)(1) above, in determining whether any rights, options
or warrants entitle the holders to subscribe for or purchase shares of the Common Stock at a price per share less than such average Closing Sale Price for the ten consecutive Trading Days immediately preceding, but excluding, the declaration date
for such distribution, and in determining the aggregate offering price of such shares of the Common Stock, there shall be taken into account any consideration received by the Company for such rights, options or warrants and any amount payable upon
exercise or conversion thereof, the value of such consideration, if other than cash, to be determined by the Board of Directors or a committee thereof. 
 (c) If the Company distributes shares of its Capital Stock, evidences of its Indebtedness or other of its securities, assets or property to all or substantially all holders of Common Stock, excluding:

 (i) dividends or distributions as to which adjustment is required to be effected pursuant to clause
(a) or (b) above; 
 (ii) rights issued to all holders of the Common Stock pursuant to a rights plan,
where such rights are not presently exercisable, trade with the Common Stock and the plan provides that Holders will receive such rights along with any Common Stock received upon conversion of the Notes; 

  
 58 

 (iii) dividends or distributions paid exclusively in cash, as to which an
adjustment is required to be effected in clause (d) below; and 
 (iv) Spin-Offs described below in this
clause (c), 
 then the Conversion Rate shall be increased based on the following formula: 

 

													
		 	CR1	  	=	  	CR0	  	×	  	 SP0
	  	
	 	  	  	  	  	    
SP0 – FMV    	  	

 where, 
  

					
	CR1	  	=	 	the Conversion Rate in effect immediately after the open of business on the Ex-Date for such distribution;
			
	CR0	  	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Date for such distribution;
			
	SP0	  	=	 	the average Closing Sale Price of the Common Stock over the ten consecutive Trading Days immediately preceding, but excluding, the Ex-Date for such distribution;
and
			
	FMV	  	=	 	the Fair Market Value (as determined by the Board of Directors or a committee thereof) of the shares of Capital Stock, evidences of Indebtedness, securities, assets or property
distributed with respect to each outstanding share of the Common Stock immediately prior to the open of business on the Ex-Date for such distribution.

 Any increase made under the portion of this clause (c) above shall become effective immediately
after the open of business on the Ex-Date for such distribution. If such distribution is not so paid or made, the Conversion Rate shall be decreased to be the Conversion Rate that would then be in effect if such distribution had not been declared.

 Notwithstanding the foregoing, if “FMV” (as defined above) is equal to or greater than
“SP0” (as defined above), or if the difference
between “SP0” and “FMV” is less than $1.00, in lieu of the foregoing increase, each Holder shall receive, in respect of each $1,000 principal amount thereof, at the same time and upon the same terms as holders of the Common Stock
without having to convert its Notes, the amount and kind of the Capital Stock, evidences of the Company’s Indebtedness, or other securities assets or property of the Company that such Holder would have received as if such Holder owned a number
of shares of Common Stock equal to the Conversion Rate in effect on the Ex-Date for the distribution. 

  
 59 

 With respect to an adjustment pursuant to this clause (c) where there has been a
payment of a dividend or other distribution on the Common Stock in shares of Capital Stock of any class or series, or similar equity interests, of or relating to a Subsidiary or other business unit of the Company that will be, upon distribution,
listed on a U.S. national or regional securities exchange (a “Spin-Off”), the Conversion Rate shall be increased based on the following formula: 
  

													
		 	CR1	  	=	  	CR0	  	×	  	     FMV + MP0    
	  	
	 	  	  	  	  	MP0	  	

 where, 
  

					
	CR1	  	=	 	Conversion Rate in effect immediately after the open of business on the Ex-Date for the Spin-Off;
			
	CR0	  	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Date for the Spin-Off;
			
	FMV	  	=	 	the average Closing Sale Price of the Capital Stock or similar equity interest distributed to holders of the Common Stock applicable to one share of the Common Stock for the ten
consecutive Trading Days immediately following the Ex-Date for such Spin-Off (such period, the “Valuation Period”); and
			
	MP0	  	=	 	the average of the Closing Sale Prices of the Common Stock over the Valuation Period.

 Any adjustment to the Conversion Rate under the preceding paragraph of this clause (c) shall be made
immediately after the close of business on the last day of the Valuation Period, but shall be given effect as of the open of business on the Ex-Date for the Spin-Off. Because the Company will make the adjustment to the Conversion Rate at the end of
the Valuation Period with retroactive effect, the Company shall delay the settlement of any Notes where the final day of the related Conversion Period occurs during the Valuation Period. In such event, the Company shall pay or deliver, as the case
may be, any cash and shares of the Common Stock due upon conversion (based on the adjusted Conversion Rate as described above) on the third Business Day immediately following the last Trading Day of the Valuation Period. 

(d) If the Company pays any cash dividends or distributions exclusively in cash to all or substantially all holders of its Common Stock
(other than dividends or distributions made in connection with the Company’s liquidation, dissolution or winding-up), the Conversion Rate shall be increased based on the following formula: 

 

													
		 	CR1	  	=	  	CR0	  	×	  	 SP0
	  	
	 	  	  	  	  	    
SP0 – C    	  	

  
 60 

 where, 
  

					
	CR1	  	=	 	the Conversion Rate in effect immediately after the open of business on the Ex-Date for such dividend or distribution;
			
	CR0	  	=	 	the Conversion Rate in effect immediately prior to the open of business on the Ex-Date for such dividend or distribution;
			
	SP0	  	=	 	the average Closing Sale Price of the Common Stock for the ten consecutive Trading Days immediately preceding, but excluding, the Ex-Date for such dividend or distribution;
and
			
	C	  	=	 	the amount in cash per share the Company distributes to holders of the Common Stock.

 Any increase made under this clause (d) shall become effective immediately after the open of
business on the Ex-Date for such dividend or distribution. If such dividend or distribution is not so paid, the Conversion Rate shall be decreased, effective as of the date the Board of Directors, or a committee thereof, determines not to make or
pay such dividend or distribution, to be the Conversion Rate that would then be in effect if such dividend or distribution had not been declared. 
 Notwithstanding the foregoing, if “C” (as defined above) is equal to or greater than “SP0” (as defined above), or if the difference between “SP0” and “C” is less than $1.00, in lieu of the foregoing increase, each Holder shall receive, in respect of
each $1,000 principal amount thereof, at the same time and upon the same terms as holders of shares of the Common Stock without having to convert its Notes, the amount of cash that such Holder would have received as if such Holder owned a number of
shares of the Common Stock equal to the Conversion Rate in effect on the Ex-Date for such cash dividend or distribution. 
 (e)
If the Company or any of its Subsidiaries makes a payment in respect of a tender offer or exchange offer for the Common Stock, to the extent that the cash and value of any other consideration included in the payment per share of the Common Stock
exceeds the Closing Sale Price of the Common Stock on the Trading Day next succeeding the last date (the “Expiration Date”) on which tenders or exchanges may be made pursuant to such tender or exchange offer, the Conversion Rate
shall be increased based on the following formula: 
  

													
		 	CR1	  	=	  	CR0	  	×	  	     AC + ( SP1 × OS1 )    
	  	
	 	  	  	  	  	OS0 ×
SP1	  	

 where, 
  

					
	CR1	  	=	 	the Conversion Rate in effect immediately after the close of business on the Trading Day immediately following the Expiration Date;
			
	CR0	  	=	 	the Conversion Rate in effect immediately prior to the close of business on the Trading Day immediately following the Expiration Date;

  
 61 

					
	AC	 	=	 	the aggregate value of all cash and any other consideration (as determined by the Board of Directors or a committee thereof) paid or payable for shares purchased in such tender or
exchange offer;
			
	SP1	 	=	 	the average Closing Sale Price of the Common Stock for the ten consecutive Trading Days next succeeding the Expiration Date (the “Averaging
Period”);
			
	OS1	 	=	 	the number of shares of the Common Stock outstanding immediately after the close of business on the Expiration Date (adjusted to give effect to the purchase or exchange of all
shares accepted for purchase in such tender offer or exchange offer); and
			
	OS0	 	=	 	the number of shares of the Common Stock outstanding immediately prior to the close of business on the Expiration Date (prior to giving effect to such tender offer or exchange
offer).

 Any adjustment to the Conversion Rate under this clause (e) shall be made immediately after the
close of business on the last day of the Averaging Period, but shall be given effect as of the open of business on the Trading Day next succeeding the Expiration Date. Because the Company shall make the adjustment to the Conversion Rate at the end
of the Averaging Period with retroactive effect, the Company shall delay the settlement of any Notes where the final day of the related Conversion Period occurs during the Averaging Period. In such event, the Company shall pay or deliver, as the
case may be, any cash and shares of the Common Stock due upon conversion (based on the adjusted Conversion Rate as described above) on the third Business Day immediately following the last day of the Averaging Period. 

(f) In the event of an increase in the Conversion Rate above that which would result in the Notes, in the aggregate, becoming convertible
into shares in excess of certain limitations set forth in the listing standards of the NYSE requiring stockholder approval, the Company shall, at its option, either obtain stockholder approval of such issuances or deliver cash in lieu of any shares
otherwise deliverable upon conversions in excess of such limitations based on the Closing Sale Price of the Common Stock on the relevant Conversion Date, in the case of Physical Settlement, or on the VWAP of the Common Stock on each Trading Day of
the relevant Conversion Period in respect of which, in lieu of delivering shares of Common Stock, the Company delivers cash pursuant to this clause (f), in the case of Combination Settlement. 

(g) To the extent that any stockholders’ rights plan adopted by the Company is in effect upon conversion of the Notes, Holders will
receive, in addition to any Common Stock due upon conversion, the rights under the applicable rights agreement. However, if, prior to any conversion, the rights have separated from the shares of the Common Stock in accordance with the provisions of
the applicable stockholders’ rights plan, the Conversion Rate will be adjusted at the time of separation as if the Company distributed to all holders of the Common Stock, shares of Capital Stock, evidences of Indebtedness, securities, assets or
property as described in clause (c) above, subject to readjustment in the event of the expiration, termination or redemption of such rights. 

  
 62 

 (h) Notwithstanding any of the foregoing clauses in this Section 10.04, the Conversion
Rate shall not be adjusted pursuant to this Section 10.04 if as a result of holding the Notes the Holders shall otherwise participate (other than in the case of a share split or share combination), at the same time and upon the same terms as
holders of the Common Stock in any of the transactions that would otherwise give rise to adjustment pursuant to this Section 10.04 without conversion of such Holder’s Notes as if such Holder held a number of shares of Common Stock equal to
the applicable Conversion Rate for each $1,000 principal amount of Notes held by such Holder. 
 (i) Except as stated in this
Section 10.04, the Company shall not adjust the Conversion Rate for the issuances of shares of Common Stock or any securities convertible into or exchangeable for shares of Common Stock or rights to purchase shares of Common Stock or such
convertible or exchangeable securities. 
 (j) Notwithstanding the foregoing, if a Conversion Rate adjustment becomes effective
on any Ex-Date as described in this Section 10.04, and a Holder that has converted its Notes on or after such Ex-Date and on or prior to the related Record Date would be treated as the record holder of the shares of the Common Stock as of the
related Conversion Date as described under Section 10.02(b) based on an adjusted Conversion Rate for such Ex-Date, then, notwithstanding the foregoing Conversion Rate adjustment provisions, such Conversion Rate adjustment relating to such
Ex-Date shall not be made for such converting Holder. Instead, such Holder shall be treated as if such Holder were the record owner of such shares of Common Stock on an unadjusted basis and participate in the related dividend, distribution or other
event giving rise to such adjustment. 
 (k) No adjustment pursuant to this Section 10.04 shall be made to the Conversion
Rate unless such adjustment would require a change of at least 1% in the Conversion Rate then in effect at such time. However, any adjustments that are less than 1% of the Conversion Rate shall be carried forward and taken into account in any
subsequent adjustment, regardless of whether the aggregate adjustment is less than 1%, (i) annually on the anniversary of the first date of original issuance of the Notes and (ii) otherwise (A) upon conversion of any Notes or
(B) with respect to any converted Notes, on each Trading Day in any relevant Conversion Period and (C) immediately prior to any Fundamental Change Repurchase Date. 
 (l) The Company shall be permitted to increase the Conversion Rate by any amount for a period of at least 20 Business Days if the Board of Directors or a committee thereof determines that such increase
would be in the best interest of the Company. The Company also may (but is not required to) increase the Conversion Rate to avoid or diminish income tax to holders of Common Stock or rights to purchase shares of Common Stock in connection with a
dividend or distribution of shares (or rights to acquire shares) or similar event. 
 (m) Whenever the Conversion Rate is
adjusted as herein provided, the Company shall file with the Trustee and record Holders of the Notes an Officers’ Certificate briefly stating the facts requiring the adjustment and the manner of computation. 

  
 63 

 (n) For purposes of this Section 10.04, the number of shares of Common Stock at any
time outstanding shall not include shares held in the treasury of the Company but shall include shares issuable in respect of scrip certificates issued in lieu of fractions of shares of Common Stock. The Company shall not pay any dividend or make
any distribution on shares of Common Stock held in the treasury of the Company. 
 (o) Whenever any provision of this Indenture
requires the Company to calculate the Closing Sale Prices, the volume-weighted average price, the Daily Conversion Values or the Daily Settlement Amounts over, or based on, a span of multiple calendar days (including a Conversion Period, Valuation
Period or Averaging Period), the Company shall make appropriate adjustments to each to account for any adjustment to the Conversion Rate that becomes effective, or any event requiring an adjustment to the Conversion Rate where the Ex-Date of the
event occurs, at any time during the period when the Closing Sale Prices, the volume-weighted average prices, the Daily Conversion Values or the Daily Settlement Amounts are to be calculated. 

 

	Section 10.05	Effect of Reclassifications, Business Combinations, Asset Sales and Corporate Events. 

In the case of: 

(a) any recapitalization, reclassification or change of the Common Stock (other than changes resulting from a subdivision or
combination); 
 (b) any consolidation, merger or combination involving the Company; 

(c) any sale, lease or other transfer to a third party of the consolidated assets of the Company and its Subsidiaries substantially as an
entirety; or 
 (d) any statutory share exchange, 
 in each case, as a result of which the Common Stock would be converted into, or exchanged for, stock, other securities, other property or assets (including cash or any combination thereof), then, at and
after the effective time of the transaction, the right to convert each $1,000 principal amount of Notes will be changed into a right to convert such principal amount of Notes into, in lieu of Common Stock, the kind and amount of shares of stock,
other securities or other property or assets (including cash or any combination thereof) that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to such transaction would have owned or been entitled to
receive (the “Reference Property”) upon such transaction. Thereafter, references in this Indenture to Common Stock shall be deemed to apply mutatis mutandis to equivalent units of Reference Property, as nearly as is practical
as determined in good faith by the Company. However, at and after the effective time of the transaction (i) the Company shall continue to have the right to determine the form of consideration to be paid or delivered, as the case may be, upon
conversion of the Notes as set forth under Section 10.02 above and (ii)(x) any amount otherwise payable in cash upon conversion of the Notes as set forth under Section 10.02 above will continue to be payable in cash, (y) the number of
shares of the Common Stock, if any, 

  
 64 

 
otherwise deliverable upon conversion of the Notes as set forth under Section 10.02 above will instead be deliverable in the amount and type of Reference Property that a holder of that
number of shares of Common Stock would have received in such transaction and (z) the volume-weighted average price will be calculated based on the value (determined in a reasonable manner selected in good faith by the Company) of a unit of
Reference Property that a holder of one share of Common Stock would have received in such transaction. If the transaction causes the Common Stock to be converted into, or exchanged for, the right to receive more than a single type of consideration
(determined based in part upon any form of stockholder election), the Reference Property into which the Notes will become convertible will be deemed to be the kind and amount of consideration actually received by holders of a majority of the Common
Stock that voted for such an election (if electing between two types of consideration) or holders of a plurality of the Common Stock that voted for such an election (if electing between more than two types of consideration), as the case may be. If
the holders of Common Stock receive only cash in such transaction, then for all conversions that occur after the effective date of such transaction (i) the consideration due upon conversion of each $1,000 principal amount of Notes shall be
solely cash in an amount equal to the Conversion Rate in effect on the Conversion Date (as may be increased by any additional shares as described under Section 10.03), multiplied by the Stock Price of Common Stock in such transaction and
(ii) the Company shall satisfy the Conversion Obligation by paying cash to converting Holders on the third Business Day immediately following the Conversion Date. The Company shall not become a party to any such transaction unless the terms of
such transaction are consistent with the foregoing. 
  

	Section 10.06	Certain Covenants. 

 (a)
The Company shall, prior to the issuance of any Notes hereunder, and from time to time as may be necessary, reserve out of its authorized but unissued Common Stock or shares of Common Stock held in treasury, a sufficient number of shares of Common
Stock, free of preemptive rights, to permit the conversion of the Notes. 
 (b) The Company covenants that all shares of Common
Stock issued upon conversion of Notes shall be duly and validly issued and fully paid and non-assessable by the Company and free from all taxes, liens and charges with respect to the issue thereof. 

(c) The Company shall endeavor promptly to comply with all federal and state securities laws regulating the issuance and delivery of
shares of Common Stock upon the conversion of Notes, if any, and shall cause to have listed or quoted and shall keep listed or quoted all such shares of Common Stock on each U.S. national securities exchange or automatic quotation system or
over-the-counter or other domestic market on which the Common Stock is then listed or quoted. 
  

	Section 10.07	Trustee Disclaimer. 

 The
Trustee shall have no duty to determine when or if an adjustment or reclassification under this Article 10 should be made, how it should be made, what any such adjustment or reclassification should be or if any adjustment or reclassification has
been performed properly. If any adjustment is made to a Conversion Rate the Trustee may accept as 

  
 65 

 
conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected in relying upon, the Officers’ Certificate delivered to the Trustee pursuant to
Section 10.04 hereof. Unless and until the Trustee receives such Officers’ Certificate, the Trustee may assume without inquiry that the Conversion Rate has not been adjusted. The Trustee makes no representations as to the validity or value
of any securities or assets issued upon conversion of the Notes, and the Trustee shall not be responsible for the Company’s failure to comply with any provision of this Article 10. 

ARTICLE 11 

SUBSIDIARY GUARANTEES 
  

	Section 11.01	Guarantee. 

 (a) The
Subsidiary Guarantors, jointly and severally, hereby fully and unconditionally guarantee (the “Subsidiary Guarantee”) to the Holders and to the Trustee the due and punctual payment of the principal of, and premium, if any, and
interest on the Notes and all other amounts due and payable under this Indenture and the Notes by the Company, when and as such principal, premium, if any, and interest shall become due and payable, whether at the stated maturity or by declaration
of acceleration, call for redemption or otherwise, according to the terms of the Notes and this Indenture, subject to the limitations set forth in Section 11.02 and 11.05. 

(b) Failing payment when due of any amount guaranteed pursuant to its Subsidiary Guarantee, for whatever reason, each of the Subsidiary
Guarantors will be jointly and severally obligated to pay the same immediately. Each Subsidiary Guarantee hereunder is intended to be a general, unsecured, senior obligation of each of the Subsidiary Guarantors and will rank pari passu in right of
payment with all debt of such Subsidiary Guarantor that is not, by its terms, expressly subordinated in right of payment to the Subsidiary Guarantee. Each of the Subsidiary Guarantors hereby agrees that its obligations hereunder shall be full,
unconditional and absolute, irrespective of the validity, regularity or enforceability of the Notes, the Subsidiary Guarantee of any other Subsidiary Guarantor or this Indenture, the absence of any action to enforce the same, any waiver or consent
by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company or any other Guarantor, or any action to enforce the same or any other circumstances which might otherwise constitute a
legal or equitable discharge or defense of the Subsidiary Guarantors. Each of the Subsidiary Guarantors hereby agrees that in the event of a default in payment of the principal of, or premium, if any, or interest on the Notes, whether at the
Maturity Date or by declaration of acceleration, call for redemption or otherwise, legal proceedings may be instituted by the Trustee on behalf of the Holders or by the Holders, on the terms and conditions set forth in this Indenture, directly
against such Subsidiary Guarantor to enforce its Subsidiary Guarantee without first proceeding against the Company or any other Subsidiary Guarantor. 
 (c) The obligations of each of the Subsidiary Guarantors under this Article 11 shall be as aforesaid full and unconditional and shall not be impaired, modified, released or limited by any occurrence or
condition whatsoever, including, without limitation, (A) any 

  
 66 

 
compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any of the obligations and liabilities of the Company or any of the other Subsidiary
Guarantors contained in the Notes or this Indenture, (B) any impairment, modification, release or limitation of the liability of the Company, any of the other Subsidiary Guarantors or any of their estates in bankruptcy, or any remedy for the
enforcement thereof, resulting from the operation of any present or future provision of any applicable bankruptcy law, or other statute or from the decision of any court, (C) the assertion or exercise by the Company, any of the other Subsidiary
Guarantors or the Trustee of any rights or remedies under the Notes or this Indenture or their delay in or failure to assert or exercise any such rights or remedies, (D) the assignment or the purported assignment of any property as security for
the Notes, including all or any part of the rights of the Company or any of the other Subsidiary Guarantors under this Indenture, (E) the extension of the time for payment by the Company or any of the other Subsidiary Guarantors of any payments
or other sums or any part thereof owing or payable under any of the terms and provisions of the Notes or this Indenture or of the time for performance by the Company or any of the other Subsidiary Guarantors of any other obligations under or arising
out of any such terms and provisions or the extension or the renewal of any thereof, (F) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of the Company or any of the other Subsidiary Guarantors
set forth in this Indenture, (G) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment
for the benefit of creditors, reorganization, arrangement, composition or readjustment of, or other similar proceeding affecting, the Company or any of the other Subsidiary Guarantors or any of their respective assets, or the disaffirmance of the
Notes, the Subsidiary Guarantee or this Indenture in any such proceeding, (H) the release or discharge of the Company or any of the other Subsidiary Guarantors from the performance or observance of any agreement, covenant, term or condition
contained in any of such instruments by operation of law, (I) the unenforceability of the Notes or this Indenture or (J) any other circumstances (other than, in each case, payment in full or discharge of all amounts guaranteed pursuant to
the Subsidiary Guarantees) which might otherwise constitute a legal or equitable discharge of a surety or guarantor. 
 (d) Each
of the Subsidiary Guarantors hereby (A) waives diligence, presentment, demand of payment, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the Company or any of the Subsidiary Guarantors, and all demands
whatsoever, (B) acknowledges that any agreement, instrument or document evidencing its Subsidiary Guarantee may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or
document evidencing the Subsidiary Guarantee without notice to it and (C) covenants that its Subsidiary Guarantee will not be discharged except by complete performance of the Subsidiary Guarantee, subject to Section 11.05. Each of the
Subsidiary Guarantors further agrees that if at any time all or any part of any payment theretofore applied by any Person to its Subsidiary Guarantee is, or must be, rescinded or returned for any reason whatsoever, including without limitation, the
insolvency, bankruptcy or reorganization of the Company or any of the Subsidiary Guarantors, the Subsidiary Guarantee shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence
notwithstanding such application, and the Subsidiary Guarantee shall continue to be effective or be reinstated, as the case may be, as though such application had not been made. 

  
 67 

 (e) Each of the Subsidiary Guarantors shall be subrogated to all rights of the Holders and
the Trustee against the Company in respect of any amounts paid by such Subsidiary Guarantor pursuant to the provisions of this Indenture, provided, however, that such Subsidiary Guarantor, shall not be entitled to enforce or to receive any
payments arising out of, or based upon, such right of subrogation until all of the Notes, all other amounts owed under this Indenture and the Subsidiary Guarantees shall have been paid in full or discharged. 

 

	Section 11.02	Limitation on Guarantor Liability. 

 Each Subsidiary Guarantor and by its acceptance hereof each Holder of a Note entitled to the benefits of the Subsidiary Guarantee hereby confirm that it is the intention of all such parties that the
guarantee by such Subsidiary Guarantor pursuant to its Subsidiary Guarantee not constitute a fraudulent transfer or conveyance for purposes of any federal or state law. To effectuate the foregoing intention, the Holders of a Note entitled to the
benefits of the Subsidiary Guarantees and the Subsidiary Guarantors hereby irrevocably agree that the obligations of each Subsidiary Guarantor under its Subsidiary Guarantee shall be limited to the maximum amount as will, after giving effect to all
other contingent and fixed liabilities of such Subsidiary Guarantor and to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Subsidiary
Guarantee, result in the obligations of such Subsidiary Guarantor under the Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under Federal or State law. 

 

	Section 11.03	Execution and Delivery of Guarantees. 

 (a) To evidence its Subsidiary Guarantee set forth in Section 11.01, each Subsidiary Guarantor agrees that this Indenture or a supplemental indenture in substantially the form attached hereto as
Exhibit C shall be executed by an Officer of such Subsidiary Guarantor or its general partner or member, as applicable, on its behalf. 
 (b) Each Subsidiary Guarantor hereby agrees that its Subsidiary Guarantee set forth in Section 11.01 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any
notation of such Subsidiary Guarantee on the Notes. 
 (c) In case the Officer whose signature is on this Indenture or

Indenture. 
  

	6.	Denominations, Transfer, Exchange

	7.	Persons Deemed Owners

	9.	Amendment, Waiver 

Subject to certain exceptions, the Indenture contains provisions permitting a modification or amendment of the Indenture or the Notes with
the written consent or affirmative vote of the Holders of a majority in aggregate principal amount of the then outstanding Notes and the waiver of any Event of Default (other than with respect to nonpayment, a failure to satisfy the Conversion
Obligation or a provision that cannot be amended without the written consent of each Holder affected) or noncompliance with any provision with the written consent of the Holders of a majority in aggregate principal amount of the then outstanding
Notes. 
 In addition, the Indenture permits an amendment of the Indenture or the Notes without the consent of any Holder under
circumstances specified in the Indenture. The Indenture also permits an amendment of the Indenture or the Notes only with the consent of any Holder affected thereby under circumstances specified in the Indenture. 

 

	10.	Defaults and Remedies 

Except as specified in the Indenture, if an Event of Default occurs (other than an Event of Default relating to certain events of
bankruptcy, insolvency or reorganization of the Company) and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the outstanding Notes may declare the principal amount of the Notes and accrued and unpaid
interest on the outstanding Notes to be due and payable. If an Event of Default relating to certain events of bankruptcy, insolvency or reorganization of the Company occurs, the principal amount of the

  
 A-7

 
Notes and accrued and unpaid interest on the outstanding Notes shall automatically become due and payable without any declaration or other act on the part of the Trustee or any Holders. Under
certain circumstances, the Holders of a majority in aggregate principal amount of the outstanding Notes may rescind any such acceleration with respect to the Notes and its consequences. 

If an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any of the rights or powers under
the Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense. Subject to certain exceptions, no Holder may pursue any remedy
with respect to the Indenture or the Notes unless (i) such Holder has given the Trustee written notice of an Event of Default, (ii) Holders of at least 25% in aggregate principal amount of the outstanding Notes have made a written request
to the Trustee to pursue the remedy and offered reasonable security or indemnity against any costs, liability or expense of the Trustee, (iii) the Trustee fails to comply with such request within 60 calendar days after receipt of such request
and the offer of indemnity and (iv) the Trustee has not received an inconsistent direction from the Holders of a majority in aggregate principal amount of the outstanding Notes. Subject to certain restrictions, the Holders of a majority in
aggregate principal amount of the outstanding Notes are given the right to direct the time, method and place of any proceedings for any remedy available to the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law
or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal liability or expense for which the Trustee has not received adequate indemnity as determined by it
in good faith. Prior to taking any action under the Indenture, the Trustee shall be entitled to indemnification satisfactory to it in its sole discretion against all losses and expenses caused by taking or not taking such action. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall impair, as among the Company and the Holder
of the Notes, the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the place, at the respective times, at the rate and in the coin or currency herein and in the Indenture
prescribed. 
  

	11.	Trustee Dealings with the Company 

 Subject to certain limitations imposed by the Trust Indenture Act, the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal
with the Company or its Affiliates with the same rights it would have if it were not Trustee. 
  

	12.	No Personal Liability of Directors, Officers, Employees and Stockholders 

 No director, officer, employee, incorporator, stockholder or partner of the Company or any Subsidiary Guarantor, as such, will have any liability for any obligations of the Company or any Subsidiary
Guarantor under the Notes or the Indenture for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder, by accepting a Note, waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes.
