 MAGMA DESIGN AUTOMATION, INC. 
 2.00% Convertible Senior Notes due 2010 
 REGISTRATION RIGHTS AGREEMENT 
 March 5, 2007 
 To the Initial Purchasers set forth on 
 Schedule A attached hereto 
 Ladies and Gentlemen: 
 Magma Design Automation, Inc., a
Delaware corporation (the “Company”), proposes to issue to the initial purchasers set forth on Schedule A attached hereto (the “Initial Purchasers”), upon the terms set forth in those certain exchange
agreements, each dated February 27, 2007 (each, an “Exchange Agreement” and, collectively, the “Exchange Agreements”), $47,439,000 aggregate principal amount of its 2.00% Convertible Senior Notes due 2010 (the
“Notes”). The Notes will be issued pursuant to an Indenture, dated as of March 5, 2007 (the “Indenture”), by and between the Company and U.S. Bank National Association, as trustee (the “Trustee”).
As an inducement to each Initial Purchaser to enter into its respective Exchange Agreement, the Company agrees with each Initial Purchaser, for the benefit of the beneficial owners (including the Initial Purchasers) from time to time of the Notes
and of the Underlying Common Stock (as defined herein) issued upon conversion of the Notes (each of the foregoing, a “Holder” and, collectively, the “Holders”), as follows: 
 1. Shelf Registration. 
 (a) The
Company shall prepare and file with the Securities and Exchange Commission (the “Commission”) in no event later than thirty (30) days (such thirtieth day being a “Filing Deadline”) after the date hereof (the
“Closing Date”), a Shelf Registration Statement for an offering to be made on a delayed or continuous basis pursuant to Rule 415 of the Securities Act of 1933, as amended (the “Securities Act”) (a “Shelf
Registration Statement”), registering the resale from time to time by the Holders thereof (who satisfy certain conditions relating to the provision of information in connection with the Shelf Registration Statement) of all of the
Registrable Securities (as defined herein) (the “Initial Shelf Registration Statement”). The Initial Shelf Registration Statement shall be on an appropriate form under the Securities Act permitting registration of such Registrable
Securities for resale by such Holders from time to time in accordance with the methods of distribution elected by the Holders and set forth in the Initial Shelf Registration Statement. The Company shall use all commercially reasonable efforts to
cause the Initial Shelf Registration Statement to first be declared effective under the Securities Act as promptly as is practicable but in any event within ninety (90) days after the Closing Date (such ninetieth day being the
“Effectiveness Deadline”; provided, however, that if the Commission reviews the Registration Statement and provides comments thereon or on any documents incorporated by reference therein, and/or requires the Company to
make modifications thereto or to any documents incorporated by reference therein, then the Effectiveness Deadline shall be extended to one hundred fifty (150) days after the Closing Date), and in accordance with the terms of this Agreement to
keep the Initial Shelf Registration Statement (or any Subsequent Shelf Registration Statement, as defined herein) continuously effective under the Securities Act to permit the prospectus included therein to be lawfully delivered by the Holders of
the Registrable Securities, for a period of two years (or for such longer period if extended pursuant to Section 2(h) below) from the Closing Date or such shorter period that will terminate when all the Registrable Securities covered by the
Shelf Registration Statement (i) have been transferred pursuant to a registration statement or Rule 144 under the Securities Act, or any successor rule thereof, (ii) are, assuming such securities are held by non-affiliates of the Company,
eligible to be sold to the public pursuant to Rule 144(k) under 

 
the Securities Act, or any successor rule thereof or (iii) have ceased to be outstanding (such period, the “Effectiveness Period”).
Subject to Section 1(d) and Section 2(h) hereof, the Company shall be deemed not to have used all commercially reasonable efforts to keep the Shelf Registration Statement continuously effective during the requisite period if it voluntarily
takes any action that would result in Holders of Registrable Securities covered thereby not being able to offer and sell such Registrable Securities during that period, unless such action is required by applicable law. At the time the Initial Shelf
Registration Statement is declared effective, each Holder who has provided the Company with an appropriately completed and executed Selling Securityholder Notice and Questionnaire (as defined herein) on or prior to the date five (5) Business
Days (as defined herein) prior to such time of effectiveness and who holds Registrable Securities, shall be named as a selling securityholder in the Initial Shelf Registration Statement and the related prospectus in such a manner as to permit such
Holder to deliver such prospectus to purchasers of Registrable Securities in accordance with applicable law. None of the Company’s securityholders (other than the Holders of Registrable Securities who satisfy certain conditions relating to the
provision of information in connection with the Shelf Registration Statement) shall have the right to include any of the Company’s securities in the Shelf Registration Statement. 
 (b) If the Initial Shelf Registration Statement or any Subsequent Shelf Registration Statement ceases to be effective for any reason at any time during
the Effectiveness Period (other than pursuant to Section 1(d) or Section 2(h) or because all Registrable Securities registered thereunder have been resold pursuant thereto or have otherwise ceased to be Registrable Securities), the Company
shall use all commercially reasonable efforts to obtain the prompt withdrawal of any order suspending the effectiveness thereof, and in any event shall within thirty (30) days of such cessation of effectiveness amend the Shelf Registration
Statement in a manner reasonably expected to obtain the withdrawal of the order suspending the effectiveness thereof, or file an additional Shelf Registration Statement covering all of the securities that as of the date of such filing are
Registrable Securities (a “Subsequent Shelf Registration Statement”). If a Subsequent Shelf Registration Statement is filed, the Company shall use all commercially reasonable efforts to cause the Subsequent Shelf Registration
Statement to become effective as promptly as is practicable after such filing and to keep such Subsequent Shelf Registration Statement continuously effective until the end of the Effectiveness Period. 
 (c) The Company shall supplement and amend the Shelf Registration Statement if required by the rules, regulations or instructions applicable to the
registration form used by the Company for such Shelf Registration Statement, if required by the Securities Act or, to the extent to which the Company does not reasonably object, as reasonably requested by the Trustee on behalf of a majority in
interest of the registered Holders. 
 (d) Each Holder of Registrable Securities agrees that if such Holder wishes to sell Registrable
Securities pursuant to a Shelf Registration Statement and related prospectus, it will do so only in accordance with this Section 1(d) and Section 2(h). Each Holder of Registrable Securities wishing to sell Registrable Securities pursuant
to a Shelf Registration Statement and related prospectus agrees to deliver an appropriately completed and executed Selling Securityholder Notice and Questionnaire to the Company at least five (5) Business Days prior to any intended effective
date of the Shelf Registration Statement. Additionally, from and after the date the Initial Shelf Registration Statement is declared effective, the Company shall, as promptly as practicable after the date an appropriately completed and executed
Selling Securityholder Notice and Questionnaire is delivered (i) (A) to the extent permitted by applicable law, within ten (10) days after such date, file with the Commission a prospectus supplement solely to name such Holder as a
selling securityholder, or (B) if required by applicable law, as promptly as practicable after such date, file with the Commission a post-effective amendment to the Shelf Registration Statement or prepare and, if required by applicable law,
file a supplement to the related prospectus or a supplement or amendment to any document incorporated therein by reference or file any other document required under the Securities Act so that the Holder delivering such Selling Securityholder Notice
and Questionnaire is named as a selling securityholder in the Shelf Registration Statement and the related prospectus in such a manner as to permit such Holder to deliver such prospectus to purchasers of the Registrable Securities in accordance with
applicable law and, if the Company shall file a post-effective amendment to the Shelf Registration Statement, use all commercially reasonable efforts to cause such post-effective amendment to be declared effective under the Securities Act as
promptly as is practicable, but in any event by the date (the “Amendment Effectiveness Deadline”) that is forty-five (45) days after the date such post-effective amendment is required by this clause to be filed;
(ii) provide such Holder copies of any documents filed pursuant to clause (i) of this Section 1(d); and (iii) notify such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective
amendment filed pursuant to clause 

 
(i) of this Section 1(d); provided that if such Selling Securityholder Notice and Questionnaire is delivered during a Deferral Period (as defined
in Section 2(h)), the Company shall so inform the Holder delivering such Selling Securityholder Notice and Questionnaire and shall take the actions set forth in clauses (i), (ii) and (iii) above upon expiration of the Deferral Period
in accordance with Section 2(h); provided, further that after the date of effectiveness of the Initial Shelf Registration Statement, the Company shall not be obligated to file more than one post-effective amendment in any 90-day
period (measured from the date any previous post-effective amendment has been filed, or in the case of the first post-effective amendment, the date the first appropriately completed and executed Selling Securityholder Notice and Questionnaire is
delivered to the Company after the date of effectiveness) for the purpose of naming Holders as selling securityholders who were not so named in the Shelf Registration Statement at the time of effectiveness. Notwithstanding anything contained herein
to the contrary, (i) the Company shall be under no obligation to name any Holder that has not timely submitted an appropriately completed and executed Selling Securityholder Notice and Questionnaire to the Company as a selling securityholder in
any Shelf Registration Statement or related prospectus and (ii) the Amendment Effectiveness Deadline shall be extended by up to ten (10) days after the expiration of a Deferral Period (and the Company shall incur no obligation to pay
Additional Interest (as defined in Section 5(a)) during such extension) if such Deferral Period is in effect on the Amendment Effectiveness Deadline. Any Holder who, subsequent to the date the Initial Shelf Registration Statement is declared
effective, provides a Selling Securityholder Notice and Questionnaire required by this Section 1(d) pursuant to the provisions of this Section (whether or not such Holder has supplied the Selling Securityholder Notice and Questionnaire at the
time the Initial Shelf Registration Statement was declared effective) shall be named as a selling securityholder in the Shelf Registration Statement and/or related prospectus, each as amended or supplemented, in accordance with the requirements of
this Section 1(d). 
 (e) Notwithstanding any other provisions of this Agreement to the contrary, the Company shall cause the Shelf
Registration Statement and the related prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement and as of the date of filing any amendment or supplement, as applicable, (i) to comply in
all material respects with the applicable requirements of the Securities Act and the rules and regulations of the Commission and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated
therein or necessary in order to make the statements therein (in the case of the prospectus, in light of the circumstances under which they were made) not misleading.

 (a) The Company shall (i) furnish
to the Notice Holders, within ten (10) days after the filing thereof with the Commission, a copy of any Shelf Registration Statement and each amendment thereof and each supplement (other than supplements that do nothing more than name Notice
Holders in the Selling Securityholder table of the Shelf Registration Statement and provide information with respect thereto), if any, to the prospectus included therein and the Company shall use all commercially reasonable efforts to reflect in the
Shelf Registration Statement, prior to effectiveness, such comments as the Notice Holders reasonably may propose; and (ii) include the names of the Notice Holders who propose to sell Registrable Securities pursuant to the Shelf Registration
Statement and who comply with the provisions hereof as selling securityholders. 
 (b) The Company shall give written notice to the Holders
(upon the occurrence of the event contemplated by clause (i) below) and the Notice Holders (upon the occurrence of any of the events contemplated by clauses (ii) through (vii) below) (which notice pursuant to clauses
(iii) through (vii) hereof shall be accompanied by an instruction to suspend the use of the prospectus until the requisite changes have been made): 
 (i) within ten (10) days after the filing of the Shelf Registration Statement (which notice may be delivered through The Depository
Trust Company, a New York corporation (“DTC”)) with the Commission; 
 (ii) when the Shelf Registration
Statement or any amendment thereto has been filed with the Commission and when the Shelf Registration Statement or any post-effective amendment thereto has become effective (which notice may be delivered through DTC); 
 (iii) of any request by the Commission for amendments or supplements to the Shelf Registration Statement or the prospectus included
therein or for additional information; 
 (iv) of the issuance by the Commission of any stop order suspending the
effectiveness of the Shelf Registration Statement or the initiation of any proceedings for that purpose; 
 (v) of the receipt
by the Company or its legal counsel of any notification with respect to the suspension of the qualification of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; 

(vi) of the happening of any event that requires the Company to make changes in the Shelf Registration Statement or the prospectus in
order that the Shelf Registration Statement or the related prospectus neither contain an untrue statement of a material fact nor omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of
the prospectus, in light of the circumstances under which they were made) not misleading; and 
 (vii) the occurrence or
existence of any pending corporate development with respect to the Company that the Company believes may be material and that, in the determination of the Company, makes it inadvisable and not in the best interest of the Company to allow continued
availability of the Shelf Registration Statement and the related prospectus. 

 (c) The Company shall make every commercially reasonable effort to obtain the withdrawal at the earliest
possible time, of any order suspending the effectiveness of the Shelf Registration Statement or the lifting of any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction in
which they have been qualified for sale. 
 (d) The Company shall furnish to each Holder of Registrable Securities named in the Shelf
Registration Statement, as amended, or any prospectus, as amended or supplemented, without charge, at least one copy of the Shelf Registration Statement and any post-effective amendment thereto, including financial statements and schedules, and, if
the Holder so requests in writing, all exhibits thereto (including those, if any, incorporated by reference). 
 (e) The Company shall,
during the Effectiveness Period, deliver to each Holder of Registrable Securities named in the Shelf Registration Statement, as amended, or any prospectus, as amended or supplemented, without charge, as many copies of the prospectus (including each
preliminary prospectus) included in the Shelf Registration Statement and any amendment or supplement thereto as such person may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the prospectus or
any amendment or supplement thereto by each of the selling Holders of the Registrable Securities in connection with the offering and sale of the Registrable Securities covered by the prospectus, or any amendment or supplement thereto, included in
the Shelf Registration Statement. 
 (f) Prior to any public offering of the Registrable Securities pursuant to any Shelf Registration
Statement the Company shall register or qualify or cooperate with the Holders of the Registrable Securities included therein and their respective counsel in connection with the registration or qualification of the Registrable Securities for offer
and sale under the securities or “blue sky” laws of such states of the United States as any Holder of Registrable Securities reasonably requests in writing and do any and all other acts or things necessary or advisable to enable the offer
and sale in such jurisdictions of the Registrable Securities covered by such Shelf Registration Statement; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where
it is not then so qualified or (ii) take any action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject. 
 (g) The Company shall cooperate with the Notice Holders to facilitate the timely preparation and delivery of certificates representing the Registrable
Securities to be sold pursuant to any Shelf Registration Statement free of any restrictive legends and in such denominations and registered in such names as the Notice Holders may request a reasonable period of time prior to sales of the Registrable
Securities pursuant to such Shelf Registration Statement. 
 (h) Upon the occurrence of any event contemplated by paragraphs
(iii) through (vi) of Section 2(b) above during the period for which the Company is required to maintain an effective Shelf Registration Statement, the Company shall promptly prepare and file a post-effective amendment to the Shelf
Registration Statement or a supplement to the related prospectus and any other required document so that, as thereafter delivered to Notice Holders or purchasers of Registrable Securities, the prospectus will not contain an untrue statement of a
material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Notice Holders in
accordance with paragraphs (iii) through (vi) of Section 2(b) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made or the Company otherwise notifies the Notice Holders of its election
to suspend the availability of the Shelf Registration Statement and related prospectus pursuant to Section 2(b)(vii) above, then the Holders shall suspend use of such prospectus (such period during which the availability of the Shelf
Registration Statement and any related prospectus is suspended being a “Deferral Period”), and the period of effectiveness of the Shelf Registration Statement provided for in Section 1(a) above shall each be extended by the
number of days from and including the date of the giving of such notice to and including the date when the Notice Holders shall have been advised in writing by the Company that the prospectus may be used or has received such amended or
supplemented prospectus pursuant to this Section 2(h). The Company will use all commercially reasonable efforts to ensure that the use of the prospectus may be resumed as promptly as is practicable, except that 

 
in the case of suspension of the availability of the Shelf Registration Statement and related prospectus pursuant to Section 2(b)(vii) above, the
Company shall not be required to take such action until such time as it shall no longer determine that continued availability of the Shelf Registration Statement and the related prospectus is inadvisable and not in the best interests of the Company.
In addition to the provisions of Section 1(d), the Company shall be entitled to exercise its right under this Section 2(h) to suspend the availability of the Shelf Registration Statement or any prospectus, without incurring or
accruing any obligation to pay Additional Interest pursuant to Section 5(a), for one or more periods not to exceed forty-five (45) days in any three (3) month period and not to exceed, in the aggregate, ninety (90) days in any
12-month period. For the avoidance of doubt, the suspension of availability of the Shelf Registration Statement or any prospectus pursuant to Section 1(d) shall not count against the periods permitted by the prior sentence. 
 (i) Not later than the effective date of the Initial Shelf Registration Statement, the Company will provide a CUSIP number for the Registrable Securities
and provide the applicable trustee with printed certificates for the Notes in a form eligible for deposit with DTC. 
 (j) The Company shall
prepare and file with the Commission such amendments and post-effective amendments to each Shelf Registration Statement as may be necessary to keep such Shelf Registration Statement continuously effective for the applicable period specified in
Section 1(a) and shall cause the related prospectus to be supplemented by any required prospectus supplement to be filed pursuant to Rule 424 (or any similar provisions then in force) under the Securities Act. The Company will comply in all
material respects with all rules and regulations of the Commission to the extent and so long as they are applicable to the Shelf Registration Statement and will make generally available to its securityholders (or otherwise provide in accordance with
Section 11(a) of the Securities Act) an earnings statement satisfying the provisions of Section 11(a) of the Securities Act, no later than forty-five (45) days (or such longer period as permitted by the Commission in the event the
Company timely files a notice with the Commission pursuant to Rule 12b-25 promulgated under the Exchange Act) after the end of a 12-month period (or ninety (90) days, if such period is a fiscal year (or such longer period as permitted by the
Commission in the event the Company timely files a notice with the Commission pursuant to Rule 12b-25 promulgated under the Exchange Act)) beginning with the first month of the Company’s first fiscal quarter commencing after the effective date
of the Shelf Registration Statement, which statement shall cover such 12-month period. 
 (k) The Company shall cause the Indenture to be
qualified under the Trust Indenture Act of 1939, as amended, in a timely manner and containing such changes, if any, as shall be necessary for such qualification. In the event that such qualification would require the appointment of a new trustee
under the Indenture, the Company shall appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture. 
 (l) The
Company may require each Notice Holder to furnish to the Company such information regarding the Notice Holder and the distribution of the Registrable Securities as the Company may from time to time reasonably require for inclusion in the Shelf
Registration Statement, and the Company may exclude from such registration the Registrable Securities of any Notice Holder that fails to furnish such information within a reasonable time after receiving such request. 
 (m) The Company shall enter into such customary agreements (including, if requested, an underwriting agreement in customary form) and take all such other
action, if any, as any Holder shall reasonably request in order to facilitate the disposition of the Registrable Securities pursuant to any Shelf Registration Statement. 
 (n) The Company shall (i) make available, at reasonable times and in a reasonable manner, for inspection by a representative of the Holders of Registrable Securities, any underwriter participating in any
disposition pursuant to the Shelf Registration Statement and any attorney, accountant or other agent retained by the Holders of Registrable Securities or any such underwriter, all relevant financial and other records, pertinent corporate documents
and properties of the Company and (ii) cause the Company’s officers, directors, employees, accountants and auditors to supply all relevant information reasonably requested by the Holders of Registrable Securities or any such underwriter,
attorney, accountant or agent in connection with the Shelf Registration Statement prior to its effectiveness, in each case, as shall be reasonably necessary to enable such persons, to conduct a reasonable investigation within the meaning of
Section 11 of the Securities Act; provided, however, that any information that is designated in writing by the Company, in good faith, as confidential at the time of delivery of such information shall 

 
be kept confidential by the Holders or any such underwriter, attorney, accountant or agent, unless such disclosure is made in connection with a court
proceeding or required by law, or such information becomes available to the public generally or through a third party without an accompanying obligation of confidentiality. 
 (o) In connection with any proposed underwritten offering, the Company, if requested by any Notice Holder of Registrable Securities named in a Shelf
Registration Statement, as amended, or any prospectus, as amended or supplemented, shall cause (i) its counsel to deliver an opinion and updates thereof relating to the Registrable Securities in customary form addressed to such Holders and the
managing underwriters, if any, thereof and dated, in the case of the initial opinion, the effective date of such Shelf Registration Statement (ii) its officers to execute and deliver all customary documents and certificates and updates thereof
requested by any underwriters of the applicable Registrable Securities; and (iii) its independent public accountants (and the independent accountants with respect to any other entity for which financial information is provided in the Shelf
Registration Statement) to provide to the selling Notice Holders of the applicable Registrable Securities and any underwriter therefor a comfort letter in customary form and covering matters of the type customarily covered in comfort letters in
connection with primary underwritten offerings, subject to receipt of appropriate documentation as contemplated, and only if permitted by Statement of Auditing Standards No. 72. 
 (p) The Company will use all commercially reasonable efforts to (a) if the Notes have been rated prior to the initial sale of such Notes, confirm
such ratings will apply to the Registrable Securities covered by a Shelf Registration Statement, or (b) if the Notes were not previously rated, cause the Registrable Securities covered by a Shelf Registration Statement to be rated with the
appropriate rating agencies, if so requested by Holders of a majority in aggregate principal amount of Registrable Securities covered by such Shelf Registration Statement, or by the managing underwriters, if any. 
 (q) In the event that any broker-dealer registered under the Exchange Act shall underwrite any Registrable Securities or participate as a member of an
underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Conduct Rules (the “Rules”) of the National Association of Securities Dealers, Inc. (“NASD”)) thereof,
whether as a Holder of such Registrable Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, the Company will assist such broker-dealer in complying with the requirements of such Rules,
including, without limitation, by (i) if such Rules, including Rule 2720, shall so require, engaging a “qualified independent underwriter” (as defined in Rule 2720) to participate in the preparation of the Shelf Registration
Statement relating to such Registrable Securities, to exercise usual standards of due diligence in respect thereto and, if any portion of the offering contemplated by such Shelf Registration Statement is an underwritten offering or is made through a
placement or sales agent, to recommend the yield of such Registrable Securities, (ii) indemnifying any such qualified independent underwriter to the extent of the indemnification of underwriters provided in Section 5 hereof and
(iii) providing such information to such broker-dealer as may be required in order for such broker-dealer to comply with the requirements of the Rules. 
 (r) The Company shall use all commercially reasonable efforts to take all other steps necessary to effect the registration of the Registrable Securities covered by a Shelf Registration Statement contemplated hereby.

 (s) The Company shall as promptly as practicable (if reasonably requested by any Holder who has timely delivered an appropriately
completed and executed Selling Securityholder Notice and Questionnaire and holds Registrable Securities incorporate in a prospectus supplement or post-effective amendment to the Shelf Registration Statement such information as such Notice Holder
shall, on the basis of an opinion of nationally recognized counsel experienced in such matters, determine to be required to be included therein and make any required filings of such prospectus supplement or such post-effective amendment;
provided, however, that the Company shall not be required to take any actions under this Section 2(s) that are not, in the reasonable opinion of counsel for the Company, in compliance with applicable law. 
 (t) The Company shall use all commercially reasonable efforts to cause the Underlying Common Stock to be listed on any securities exchange or any
automated quotation system on which similar securities issued by the Company are then listed, to the extent the Underlying Common Stock satisfies applicable listing requirements. 

 3. Registration Expenses. 
 (a) All expenses incurred by the Company and incident to the Company’s performance of and compliance with this Agreement will be borne by the

including special experts, retained by the Company.

such Shelf Registration Statement (not to exceed $5,000 in the aggregate); and (ii) in the event of an underwritten offering pursuant to Section 7, the reasonable fees and disbursements of one (1) firm of legal counsel named by the
Managing Underwriters (not to exceed $5,000 in the aggregate). 
 4. Indemnification. 
 (a) The Company agrees to indemnify and hold harmless each Holder of Registrable Securities and each person, if any, who controls such Holder within the
meaning of the Securities Act or the Exchange Act (each Holder and such controlling persons are referred to collectively as the “Indemnified Parties”) from and against any losses, claims, damages or liabilities, joint or several, or
any actions in respect thereof (including, but not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of the Registrable Securities) to which each Indemnified Party may become subject under the Securities
Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in a Shelf Registration Statement or
prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration Statement, or arise out of, or are based upon, the omission or alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, and shall reimburse, as incurred, the Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such
loss, claim, damage, liability or action in respect thereof; provided, however, that (i) the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any
untrue statement or alleged untrue statement or omission or alleged omission made in a Shelf Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration in reliance
upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein and (ii) with respect to any untrue statement or omission or alleged untrue
statement or omission made in any preliminary prospectus relating to a Shelf Registration Statement, the indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Holder from whom the person asserting any such
losses, claims, damages or liabilities purchased the Registrable Securities concerned, to the 

 
extent that a prospectus relating to such Registrable Securities was required to be delivered by such Holder under the Securities Act in connection with such
purchase and any such loss, claim, damage or liability of such Holder results from the fact that there was not sent or given to such person, at or prior to the written confirmation of the sale of such Registrable Securities to such person, a copy of
the final prospectus if the Company had previously furnished copies thereof to such Holder; provided further, however, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to
such Indemnified Party. The Company shall also indemnify any underwriters, their officers and directors and each person who controls such underwriters within the meaning of the Securities Act or the Exchange Act to the same extent as provided above
with respect to the indemnification of the Holders if requested by such Holders. 
 (b) Each Holder of Registrable Securities, severally and
not jointly, will indemnify and hold harmless the Company and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act from and against any losses, claims, damages or liabilities or any actions in
respect thereof, to which the Company or any such controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in a Shelf Registration Statement or prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to a Shelf Registration, or arise out of or
are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or omission or alleged untrue statement or
omission was made in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein; and, subject to the limitation set forth
immediately preceding this clause, shall reimburse, as incurred, the Company for any legal or other expenses reasonably incurred by the Company or any such controlling person in connection with investigating or defending any loss, claim, damage,
liability or action in respect thereof. This indemnity agreement will be in addition to any liability which such Holder may otherwise have to the Company or any of its controlling persons. The Holder shall also indemnify any underwriters, their
officers and directors and each person who controls such underwriters within the meaning of the Securities Act or the Exchange Act to the same extent as provided above with respect to the indemnification of the Company if requested by the Company.

 (c) Promptly after receipt by an indemnified party under this Section 4 of notice of the commencement of any action or proceeding
(including a governmental investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 4, notify the indemnifying party of the commencement thereof; but the omission
so to notify the indemnifying party will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. In case any such
action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after
notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof the indemnifying party will not be liable to such indemnified party under this Section 4 for any legal or other expenses, other than
reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof. Notwithstanding the indemnifying party’s election to assume the defense of the indemnified party in an action, the
indemnified party shall have the right to employ separate counsel (including local counsel) and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel (and local counsel) if (i) the use of counsel
chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party,
(iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party
shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened
action in respect of which any indemnified party is or could have been a 

 
party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes an unconditional release of such indemnified
party from all liability on any claims that are the subject matter of such action, and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 
 (d) If the indemnification provided for in this Section 4 is unavailable or insufficient to hold harmless an indemnified party under subsections
(a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to in
subsection (a) or (b) above in such proportion as is appropriate to reflect the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions that
resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or such Holder or such other indemnified party, as the case may be, on
the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities
referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject
of this subsection (d). Notwithstanding any other provision of this Section 4(d), the Holders of Registrable Securities shall not be required to contribute any amount in excess of the amount by which the net proceeds received by such
Holders from the sale of the Registrable Securities pursuant to a Shelf Registration Statement exceeds the amount of damages which such Holders have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or
alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For
purposes of this subsection (d), each person, if any, who controls such indemnified party within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such indemnified party and each person, if any, who
controls the Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Company. 
 (e) The agreements contained in this Section 4 shall survive the sale of the Registrable Securities pursuant to a Shelf Registration Statement and shall remain in full force and effect, regardless of any termination or cancellation of
this Agreement or any investigation made by or on behalf of any indemnified party. 
 5. Additional Interest Under Certain Circumstances.

 (a) Additional interest (the “Additional Interest”) with respect to the Notes that are Registrable Securities
shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (iv) below being herein called a “Registration Default”): 
  

	 	(i)	the Initial Shelf Registration Statement required by this Agreement is not filed with the Commission on or prior to the Filing Deadline; 

  

	 	(ii)	the Initial Shelf Registration Statement required by this Agreement is not first declared effective by the Commission on or prior to the Effectiveness Deadline;

  

	 	(iii)	the Company has failed to perform its obligations set forth in Section 1(d) within the time period required therein; or 

  

	 	(iv)	 any Shelf Registration Statement required by this Agreement has been declared effective by the Commission but such Shelf Registration Statement or related
prospectus thereafter ceases to be effective or useable (subject to the Company’s right to suspend the use of the Shelf Registration Statement and the prospectus as set forth in Section 1(d) and Section 2(h)) in accordance with the
provisions of this Agreement and during the periods specified herein and (A) the Company does not cure the Shelf Registration Statement within five (5) Business Days (which shall not be deemed 

	 	 
to extend the incurrence and accrual of any obligation to pay Additional Interest beyond the time provided for in the second to last sentence of
Section 2(h)) after it ceases to be effective or useable by a post-effective amendment or additional Shelf Registration Statement being filed and declared effective or a report filed pursuant to the Exchange Act or (B) if applicable, the
Company does not terminate any Deferral Period within the time provided for in the second to last sentence of Section 2(h). 

 Each of
the foregoing will constitute a Registration Default whatever the reason for any such event and whether it is voluntary or involuntary or is beyond the control of the Company or pursuant to operation of law or as a result of any action or inaction
by the Commission. 
 Additional Interest shall accrue on the Notes that are Registrable Securities from and including the date on which any
such Registration Default shall occur to but excluding the date on which all such Registration Defaults have been cured, at a rate of the Additional Interest Rate of the aggregate principal amount of the Notes that are Registrable Securities. The
“Additional Interest Rate” shall mean (A) for periods that only include Business Days on or before the day that is 90 days after the commencement of a Registration Default, 0.25% per annum, (B) for periods that only
include days after the date that is 90 days after the commencement of a Registration Default, 0.50% per annum and (C) for periods that include days both before and after the date that is 90 days after the commencement of a Registration
Default, a percentage equal to a fraction, the numerator of which shall be the sum of (i) the number of days in such period that are on or before the date that is 90 days after the commencement of such Registration Default multiplied by 0.25%
and (ii) the number of days in such period that are after the date that is 90 days after the commencement of such Registration Default multiplied by 0.50% and the denominator of which shall be the total number of days comprising such period. In
the case of Additional Interest accruing solely as a result of a Registration Default of the type described in Section 5(a)(iii), such Additional Interest shall be paid only to the Notice Holders that have delivered appropriately completed and
executed Selling Securityholder Notice and Questionnaires that caused the Company to incur the obligations set forth in Section 1(d) the non-performance of which is the basis of such Registration Default. Notwithstanding the foregoing, no
Additional Interest shall accrue as to any Registrable Security from and after the earlier of (x) the date such security is no longer a Registrable Security and (y) the expiration of the Effectiveness Period. The rate of accrual of the
Additional Interest with respect to any period shall not exceed the rate provided for in this paragraph notwithstanding the occurrence of multiple concurrent Registration Defaults. Following the cure of all Registration Defaults requiring the
payment by the Company of Additional Interest to the Notice Holders of Notes that are Registrable Securities pursuant to this Section, the accrual of Additional Interest will cease (without in any way limiting the effect of any subsequent
Registration Default requiring the payment of Additional Interest by the Company). 
 If a Notice Holder has converted some or all of its
Notes into Common Stock, the Holder will not be entitled to receive any Additional Interest with respect to such Common Stock or the principal amount of the Notes that have been so converted. In addition, in no event will Additional Interest be
payable in connection with a Registration Default relating to a failure to register the Underlying Common Stock. For the avoidance of doubt, if the Company fails to register both the Notes and the Underlying Common Stock, then Additional Interest
will be payable solely in connection with the Registration Default relating to the failure to register the Notes. 
 No other monetary
damages shall be available to the Holders of Registrable Securities for a Registration Default. 
 The Trustee shall be entitled, on behalf
of Holders of Notes or Underlying Common Stock, to seek any available remedy for the enforcement of this Agreement, including, with respect to Holders of Notes, for the payment of any Additional Interest. 
 All of the Company’s obligations set forth in this Section 5 that are outstanding with respect to any Registrable Security at the time such
security ceases to be a Registrable Security shall survive until such time as all such obligations with respect to such security have been satisfied in full. 
 The parties hereto agree that the Additional Interest provided for in this Section 5 constitutes a reasonable estimate of the damages that may be incurred by Holders of Notes that are Registrable Securities by
reason of the failure of the Initial Shelf Registration Statement to be filed or declared effective or available for effecting resales of Notes that are Registrable Securities in accordance with the provisions hereof. 

 (b) Any amounts of Additional Interest due pursuant to Section 5(a) will be payable in cash
semiannually in arrears with the first semiannual payment due on the first May 15 or November 15 on which such Additional Interest begins to accrue. The amount of Additional Interest will be determined by multiplying the applicable
Additional Interest Rate by the principal amount of the Notes that are Registrable Securities, and further multiplied by a fraction, the numerator of which is the number of days such Additional Interest Rate was applicable during such period
(determined on the basis of a 360-day year comprised of twelve 30-day months), and the denominator of which is 360. The Notes that are Registrable Securities entitled to payment of Additional Interest shall be determined as of the Business Day
immediately preceding the next payment date for Additional Interest with respect to the Registrable Securities. 
 6. Rules 144 and
144A. The Company shall use all commercially reasonable efforts to file the reports required to be filed by it under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports,
it will, upon the request of any Holder, make publicly available other information so long as necessary to permit sales of their securities pursuant to Rules 144 and 144A. The Company covenants that it will take such further action as any
Holder may reasonably request, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rules 144 and
144A (including the requirements of Rule 144A(d)(4)). The Company will provide a copy of this Agreement to prospective purchasers of Notes identified to the Company by the Initial Purchasers upon request. Upon the request of any Notice Holder
of Notes, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in this Section 6 shall be deemed to require the Company to register any of its
securities pursuant to the Exchange Act. 
 7. Underwritten Registrations. If any of the Registrable Securities covered by any Shelf
Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will administer the offering (the “Managing Underwriter”) will be selected by the Holders of a
majority in aggregate principal amount of such Registrable Securities to be included in such offering (provided that Holders of Common Stock issued upon conversion of the Notes shall not be deemed holders of Common Stock, but shall be deemed to be
holders of the aggregate principal amount of Notes from which such Common Stock was converted), provided, however, that such Managing Underwriters will be reasonably acceptable to the Company. 
 No person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person’s Registrable Securities
on the basis reasonably provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting
agreements and other documents reasonably required under the terms of such underwriting arrangements. 
 8. Miscellaneous. 

(a) Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations under Section 1 and 2
hereof may result in material irreparable injury to the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, any Holder may
obtain such relief as may be required to specifically enforce the Company’s obligations under Sections 1 and 2 hereof. The Company further agrees to waive the defense in any action for specific performance that a remedy at law would be
adequate. 
 (b) No Inconsistent Agreements. The Company will not on or after the date of this Agreement enter into any agreement with
respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof and will not enter into any agreement granting the holders of Common Stock rights to
participate in the Initial Shelf Registration Statement or the Shelf Registration Statement. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the
Company’s securities under any agreement in effect on the date hereof. The Company represents and warrants that, other than Holders of Notes, no holders of shares of Common Stock have the right to participate in the Initial Shelf Registrations
Statement or the Shelf Registration Statement. 

 (c) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the Holders of a majority in principal amount of the Registrable Securities affected by such amendment,
modification, supplement, waiver or consents (provided that Holders of Common Stock issued upon conversion of Notes shall not be deemed holders of Common Stock, but shall be deemed to be holders of the aggregate principal amount of Notes from which
such Common Stock was converted). 
 (d) Notices. All notices and other communications provided for or permitted hereunder shall be
made in writing by hand delivery, first-class mail, facsimile transmission, or air courier that guarantees overnight delivery: 
 (1) if to a
Holder of the Registrable Securities, at the most current address given by such Holder to the Company. 
 (2) if to the Company, at its
address as follows: 
    if prior to March 12, 2007:

 The Company by notice to any Holder may designate additional or different addresses for subsequent notices or communications
from such Holder. All such notices and communications shall be deemed to have been duly given: at the time delivered by hand, if personally delivered; three business days after being deposited in the mail, postage prepaid, if mailed; when
receipt is acknowledged by recipient’s facsimile machine operator, if sent by facsimile transmission; and on the day delivered, if sent by overnight air courier guaranteeing next day delivery. 
 (e) Third-Party Beneficiaries. The Holders shall be third-party beneficiaries to the agreements made hereunder between the Company, on the one
hand, and the Initial Purchasers, on the other hand, and shall have the right to enforce such agreements directly to the extent they may deem such enforcement necessary or advisable to protect their rights or the rights of Holders hereunder.

 (f) Successors and Assigns. This Agreement shall be binding upon the Company and its successors and assigns. 

 (g) Counterparts. This Agreement may be executed in any number of counterparts and by the parties
hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. 
 (h) Headings. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning hereof.

 (i) Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK WITHOUT
REGARD TO PRINCIPLES OF CONFLICTS OF LAWS. 
 (j) Severability. If any one or more of the provisions contained herein, or the
application thereof in any circumstance, is held invalid, illegal or unenforceable, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions contained herein shall not be affected or
impaired thereby. 
 (k) Securities Held by the Company. Whenever the consent or approval of Holders of a specified percentage of
principal amount of Registrable Securities is required hereunder, Registrable Securities held by the Company or its affiliates (other than subsequent Holders of Registrable Securities if such subsequent Holders are deemed to be affiliates solely by
reason of their holdings of such Registrable Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage. 

 If the foregoing is in accordance with your understanding of our agreement, please sign and return to the
Initial Purchasers a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement between the Initial Purchasers and the Company in accordance with its terms.

	(9)	Plan of Distribution: 

 Except as set forth below, the
undersigned Selling Securityholder (including its donees and pledgees) intends to distribute the Registrable Securities listed above in Item (3) pursuant to the Shelf Registration Statement only as follows (if at all): Such Registrable
Securities may be sold from time to time directly by the undersigned Selling Securityholder or, alternatively, in accordance with the Registration Rights Agreement, through underwriters, broker-dealers or agents. If the Registrable Securities are
sold through underwriters or broker-dealers, the Selling Securityholders will be responsible for underwriting discounts or commissions or agent commissions. Such Registrable Securities may be sold in one or more transactions at fixed prices, at
prevailing market prices at the time of sale, at varying prices determined at the time of sale, or at negotiated prices. Such sales may be effected in transactions (which may involve cross or block transactions) (i) on any national securities
exchange or quotation service on which the Registrable Securities may be listed or quoted at the time of sale, (ii) in the over-the-counter market, (iii) in transactions otherwise than on such exchanges or services or in the
over-the-counter market, or (iv) through the writing of options. In connection with sales of the Registrable Securities or otherwise, the undersigned Selling 

 
Securityholder may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the Registrable Securities in the
course of hedging positions they assume. The undersigned Selling Securityholder may also sell Registrable Securities short and deliver Registrable Securities to close out short positions, or loan or pledge Registrable Securities to broker-dealers
that in turn may sell such securities. 
 State any exceptions here:                               
                                        
                                        
                                        
                                        
        
 Note: In no event will such method(s) of distribution take the form of an underwritten offering of the
Registrable Securities without the prior agreement of the Company. 
 The undersigned Selling Securityholder acknowledges that it understands
its obligations to comply with the provisions of the Securities Exchange Act of 1934, as amended, and the rules thereunder relating to stock manipulation, particularly Regulation M thereunder (or any successor rules or regulations), in connection
with any offering of Registrable Securities pursuant to the Shelf Registration Agreement. The undersigned agrees that neither it nor any person acting on its behalf will engage in any transaction in violation of such provisions. 
 Pursuant to the Registration Rights Agreement, the Company has agreed under certain circumstances to indemnify the Selling Securityholder against certain
liabilities. 
 In the event the undersigned transfers all or any portion of the Registrable Securities listed in Item (3) above after
the date on which such information is provided to the Company other than pursuant to the Shelf Registration Statement, the undersigned agrees to notify the transferee(s) at the time of the transfer of its rights and obligations under this Selling
Securityholder Notice and Questionnaire and the Registration Rights Agreement. 
 In accordance with the undersigned’s obligation under
the Registration Rights Agreement to provide such information as may be required by law or by the staff of the Commission for inclusion in the Shelf Registration Statement, the undersigned agrees to promptly notify the Company of any inaccuracies or
changes in the information provided herein that may occur subsequent to the date hereof at anytime while the Shelf Registration Statement remains effective. All notices hereunder and pursuant to the Registration Rights Agreement shall be made in
writing, by hand-delivery, first-class mail, or air courier guaranteeing overnight delivery to the address set forth below. 
 By signing
below, the undersigned consents to the disclosure of the information contained herein in its answers to Items (1) through (9) above and the inclusion of such information in the Shelf Registration Statement and the related prospectus. The
undersigned understands that such information will be relied upon by the Company in connection with the preparation or amendment of the Shelf Registration Statement and the related prospectus. 
 Once this Selling Securityholder Notice and Questionnaire is executed by the undersigned and received by the Company, the terms of this Selling
Securityholder Notice and Questionnaire, and the representations, warranties and agreements contained herein, shall be binding on, shall inure to the benefit of and shall be enforceable by the respective successors, heirs, personal representatives,
and assigns of the Company and the undersigned with respect to the Registrable Securities beneficially owned by the undersigned and listed in Item (3) above. This Selling Securityholder Notice and Questionnaire shall be governed in all respects
by the laws of the State of New York. 
 IN WITNESS WHEREOF, the undersigned, by authority duly given, has caused this Selling Securityholder Notice and
Questionnaire to be executed and delivered either in person or by its duly authorized agent.

 The Securities and the Trustee’s certificate of authentication shall be substantially in the respective forms set forth in Exhibit A,
which Exhibit is incorporated in and made part of this Indenture. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage. The Company shall provide any such notations, legends or endorsements to
the Trustee in writing. Each Security shall be dated the date of its authentication. The Securities are being offered and sold by the Company pursuant to Exchange Agreements, each dated February __, 2007, between the Company and the initial
purchasers of the Initial Securities, in transactions exempt from, or not subject to, the registration requirements of the Securities Act. 
 (a) Restricted Global Securities. All of the Securities are initially being issued to qualified institutional buyers as defined in Rule 144A (collectively, “QIBs” or, individually, each a “QIB”) and shall be
issued initially in the form of one or more Restricted Global Securities, which shall be deposited on behalf of the purchasers of the Securities represented thereby with the Trustee, at its Corporate Trust Office, as custodian for the depositary,
The Depository Trust Company (“DTC”) (such depositary, or any successor thereto, being hereinafter referred to as the “Depositary”), and registered in the name of its nominee, Cede & Co., for the accounts of
participation in the Depositary duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of the Restricted Global Securities may from time to time be increased or decreased by adjustments

Notwithstanding the foregoing, nothing herein shall (A) 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
(B) impair, as between the Depositary and its Agent Members, the operation of customary practices governing the exercise of the rights of a Holder of any Security.

HEREINAFTER REFERRED TO AND IS REGISTERED IN THE NAME OF A DEPOSITARY OR A NOMINEE THEREOF. THIS SECURITY IS EXCHANGEABLE FOR SECURITIES REGISTERED IN THE NAME OF A PERSON OTHER THAN THE DEPOSITARY OR ITS NOMINEE ONLY IN THE LIMITED CIRCUMSTANCES
DESCRIBED IN THE INDENTURE AND, UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE
DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.” 
 SECTION 2.2. EXECUTION AND AUTHENTICATION.
 An Officer shall sign the Securities for the Company by manual or facsimile signature attested by the manual or facsimile signature of the Secretary or an Assistant Secretary of the Company. Typographic and other
minor errors or defects in any such facsimile signature shall not affect the validity or enforceability of any Security which has been authenticated and delivered by the Trustee. 
 If an Officer whose signature is on a Security no longer holds that office at the time the Trustee authenticates the Security, the Security shall be
valid nevertheless. 
 A Security shall not be valid until an authorized signatory of the Trustee manually signs the certificate of
authentication on the Security. The signature shall be conclusive evidence that the Security has been authenticated under this Indenture. 
 The Trustee shall authenticate and make available for delivery Initial Securities for original issue in the aggregate principal amount of up to $47,439,000 upon receipt of a written order or orders of the Company signed by two Officers of
the Company (a “Company Order”). The Company Order shall specify the amount of Securities to be authenticated, shall provide that all such Securities will be represented by a Restricted Global Security and the date on which each original
issue of Securities is to be authenticated. The aggregate principal amount of Initial Securities outstanding at any time may not exceed $47,439,000 except as provided in Section 2.7. The Company may, from time to time after the execution of
this Indenture, execute and deliver to the Trustee for authentication Additional Securities, and the Trustee shall thereupon authenticate and deliver said Additional Securities to or upon the written order of the Company, without any further action
by the Company hereunder; provided however that the Company may issue Additional Securities only if: (1)

  

 -10- 

 
such Additional Securities and Initial Securities are treated as part of the same issue of debt instruments for purposes of U.S. federal income tax laws;
(2) such Additional Securities shall have the same CUSIP number as the Initial Securities; and (3) the Trustee receives an Officers’ Certificate and an Opinion of Counsel to the effect that such issuance of Additional Securities
complies with the provisions of this Indenture, including each provision of this paragraph. 
 The Trustee shall act as the initial
authenticating agent. Thereafter, the Trustee may appoint an authenticating agent acceptable to the Company to authenticate Securities. An authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in this
Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent shall have the same rights as an Agent to deal with the Company or an Affiliate of the Company. 
 The Securities shall be issuable only in registered form without coupons and only in denominations of $1,000 principal amount and any integral multiple
thereof. 
 SECTION 2.3. REGISTRAR, PAYING AGENT AND CONVERSION AGENT.

“Registrar”), one or more offices or agencies where Securities may be presented for payment (each, a “Paying Agent”), one or more offices or agencies where Securities may be presented for conversion (each, a “Conversion
Agent”) and one or more offices or agencies where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served. The Company will at all times maintain a Paying Agent, Conversion Agent, Registrar and
an office or agency where notices and demands to or upon the Company in respect of the Securities and this Indenture may be served in the Borough of Manhattan, The City of New York. One of the Registrars (the “Primary Registrar”) shall
keep a register of the Securities and of their transfer and exchange. 
 The Company shall enter into an appropriate agency agreement with
any 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 Agent not a party to this Indenture. If the
Company fails to maintain a Registrar, Paying Agent, Conversion Agent or agent for service of notices and demands in any place required by this Indenture, or fails to give the foregoing notice, the Trustee shall act as such. The Company or any
Affiliate of the Company may act as Paying Agent (except for the purposes of Section 6.1 and Article 10). 
 The Company hereby
initially designates the Trustee as Paying Agent, Registrar, Custodian and Conversion Agent, and each of the Corporate Trust Office of the Trustee and the office or agency of the Trustee in the Borough of Manhattan, The City of New York (which shall
initially be the Trustee), one such office or agency of the Company for each of the aforesaid purposes. 
 SECTION 2.4. PAYING AGENT
TO HOLD MONEY IN TRUST.
 Prior to 11:00 a.m., New York City time, on each due date of the principal of or interest (including any
Additional Interest and/or Extension Fee), if any, on any Securities, the Company shall deposit with a Paying Agent a sum sufficient to pay such principal or interest (including any Additional Interest and/or Extension Fee), if any, so becoming due.
Subject to Section 10.2, a 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 principal of or interest (including any Additional Interest and/or Extension Fee), if
any, on the Securities, and shall notify the 

  

 -11- 

 
Trustee of any default by the Company (or any other obligor on the Securities) in making any such payment. If the Company or an Affiliate of the Company acts
as Paying Agent, it shall, before 11:00 a.m., New York City time, on each due date of the principal of or interest (including any Additional Interest and/or Extension Fee), if any, on any Securities, segregate the money 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 the Trustee may at any time during the continuance of any default, upon written request to a Paying Agent, require such Paying Agent to
pay forthwith to the Trustee all sums so held in trust by such Paying Agent. Upon doing so, the Paying Agent (other than the Company) shall have no further liability for the money. 
 SECTION 2.5. HOLDERS 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. If the Trustee is not the Primary Registrar, the Company shall furnish to the Trustee on or before
any Interest Payment Date, if any, 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. 
 SECTION 2.6. TRANSFER AND EXCHANGE.
 (a) Subject to compliance with any applicable additional requirements contained in Section 2.12, when a Security is presented to a Registrar with a request to register a transfer thereof or to exchange such Security for an equal
principal amount of Securities of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested; provided, however, that every Security presented or surrendered for registration of transfer
or exchange shall be duly endorsed or accompanied by an assignment form and, if applicable, a transfer certificate each in the form included in Exhibit A, and in form satisfactory to the Registrar duly executed by the Holder thereof or
its attorney duly authorized in writing. To permit registration of transfers and exchanges, upon surrender of any Security for registration of transfer or exchange at an office or agency maintained pursuant to Section 2.3, the Company shall
execute and the Trustee shall authenticate Securities of a like aggregate principal amount at the Registrar’s request. Any exchange or transfer shall be without charge, except that the Company or the Registrar may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in relation thereto, and provided, that this sentence shall not apply to any exchange pursuant to Section 2.10, 2.12(a), 3.5, 4.2 (penultimate paragraph)
or 11.5. 
 Neither the Company, any Registrar nor the Trustee shall be required to exchange or register a transfer of any Securities or
portions thereof in respect of which a Designated Event Purchase Notice has been delivered and not withdrawn by the Holder thereof (except, in the case of the purchase of a Security in part, the portion thereof not to be purchased). 
 All Securities issued upon any transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt and entitled to the
same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. 
 (b) Any Registrar appointed pursuant to
Section 2.3 hereof shall provide to the Trustee such information as the Trustee may reasonably require in connection with the delivery by such Registrar of Securities upon transfer or exchange of Securities. 
  

 -12- 

 (c) Each Holder of a Security agrees to indemnify the Company and the Trustee against any liability that
may result from the transfer, exchange or assignment of such Holder’s Security in violation of any provision of this Indenture and/or applicable United States federal or state securities law. 
 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 Security (including any transfers between or among Agent Members or other beneficial owners of interests in any Global Security) 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 2.7. REPLACEMENT SECURITIES.
 If any mutilated Security is surrendered to the Company, a Registrar or the Trustee, or the Company, a Registrar and the Trustee receive evidence to their
satisfaction of the destruction, loss or theft of any Security, and there is delivered to the Company, the applicable Registrar and the Trustee such security or indemnity as will be required by them to save each of them harmless, then, in the
absence of notice to the Company, such Registrar or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute, and upon its written request the Trustee shall authenticate and deliver, in exchange for any
such mutilated Security or in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and principal amount, bearing a number not contemporaneously outstanding. 
 In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, or is about to be purchased by the
Company pursuant to Article 3, the Company in its discretion may, instead of issuing a new Security, pay or purchase such Security, as the case may be. 
 Upon the issuance of any new Securities under this Section 2.7, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and
any other reasonable expenses (including the reasonable fees and expenses of the Trustee or the Registrar) in connection therewith. 
 Every
new Security issued pursuant to this Section 2.7 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen
Security shall be at any time enforceable by anyone, and shall be entitled to all benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder. 
 The provisions of this Section 2.7 are (to the extent lawful) exclusive and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 
 SECTION 2.8. OUTSTANDING
SECURITIES.
 Securities outstanding at any time are all Securities authenticated by the Trustee, except for those canceled by it, those
converted pursuant to Article 4, those delivered to it for cancellation or surrendered for transfer or exchange and those described in this Section 2.8 as not outstanding. 
  

 -13- 

 If a Security is replaced pursuant to Section 2.7, it ceases to be outstanding unless the Company
receives proof satisfactory to it that the replaced Security is held by a bona fide purchaser. 
 If a Paying Agent (other than the Company
or an Affiliate of the Company) holds on a Designated Event Purchase Date or the Final Maturity Date money sufficient to pay the principal of (including premium, if any) and interest (including any Additional Interest and/or Extension Fee), if any,
on Securities (or portions thereof) payable on that date, then on and after such Designated Event Purchase Date or the Final Maturity Date, as the case may be, such Securities (or portions thereof, as the case may be) shall cease to be outstanding
and interest (including any Additional Interest and/or Extension Fee), if any, on them shall cease to accrue. 
 Subject to the restrictions
contained in Section 2.9, a Security does not cease to be outstanding because the Company or an Affiliate of the Company holds the Security. 
 SECTION 2.9. TREASURY SECURITIES.
 In determining whether the Holders of the required principal amount of Securities
have concurred in any notice, direction, waiver or consent, Securities owned by the Company or any other obligor on the Securities or by any Affiliate of the Company or of such other obligor shall be disregarded, except that, for purposes of
determining whether the Trustee shall be protected in relying on any such notice, direction, waiver or consent, only Securities which a Trust Officer of the Trustee actually knows are so owned shall be so disregarded. Securities so owned which have
been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to the Securities and that the pledgee is not the Company or any other obligor on the
Securities or any Affiliate of the Company or of such other obligor. 
 SECTION 2.10. TEMPORARY SECURITIES.
 Until definitive Securities are ready for delivery, the Company may prepare and execute, and, upon receipt of a Company Order, the Trustee shall
authenticate and deliver, temporary Securities. Temporary Securities shall be substantially in the form of definitive Securities but may have variations that the Company with the consent of the Trustee considers appropriate for temporary Securities.
Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate and deliver definitive Securities in exchange for temporary Securities. 
 SECTION 2.11. CANCELLATION.
 The Company at any time may deliver Securities to the Trustee for
cancellation. The Registrar, the Paying Agent and the Conversion Agent shall forward to the Trustee or its agent any Securities surrendered to them for transfer, exchange, payment or conversion. The Trustee and no one else shall cancel, in
accordance with its standard procedures, all Securities surrendered for transfer, exchange, payment, conversion or cancellation and shall deliver the canceled Securities to the Company. All Securities which are purchased or otherwise acquired by the
Company or any of its Subsidiaries prior to the Final Maturity Date shall be delivered to the Trustee for cancellation, and the Company may not hold or resell such Securities or issue any new Securities to replace any such Securities or any
Securities that any Holder has converted pursuant to Article 4. 
  

 -14- 

 SECTION 2.12. LEGEND; ADDITIONAL TRANSFER AND EXCHANGE REQUIREMENTS.
 (a) If Securities are issued upon the transfer, exchange or replacement of Securities subject to restrictions on transfer and bearing the legends set
forth on the forms of Securities attached hereto as Exhibit A (collectively, the “Legend”), or if a request is made to remove the Legend on a Security, the Securities so issued shall bear the Legend, or the Legend shall not be
removed, as the case may be, unless there is delivered to the Company and the Registrar such satisfactory evidence, which shall include an opinion of counsel if requested by the Company or such Registrar, as may be reasonably required by the Company
and the Registrar, that neither the Legend nor the restrictions on transfer set forth therein are required to ensure that transfers thereof comply with the provisions of Rule 144A, Rule 144 or Regulation S under the Securities Act or
that such Securities are not “restricted” within the meaning of Rule 144 under the Securities Act; provided that no such evidence need be supplied in connection with the sale of such Security pursuant to a registration
statement that is effective at the time of such sale. Upon (i) provision of such satisfactory evidence if requested, or (ii) notification by the Company to the Trustee and Registrar of the sale of such Security pursuant to a registration
statement that is effective at the time of such sale, the Trustee, at the written direction of the Company, shall authenticate and deliver a Security that does not bear the Legend. If the Legend is removed from the face of a Security and the
Security is subsequently held by an Affiliate of the Company, the Legend shall be reinstated. 
 (b) A Global Security may not be
transferred, in whole or in part, to any Person other than the Depositary or a nominee or any successor thereof, and no such transfer to any such other Person may be registered; provided that the foregoing shall not prohibit any
transfer of a Security that is issued in exchange for a Global Security but is not itself a Global Security. No transfer of a Security to any Person shall be effective under this Indenture or the Securities unless and until such Security has been
registered in the name of such Person. Notwithstanding any other provisions of this Indenture or the Securities, transfers of a Global Security, in whole or in part, shall be made only in accordance with this Section 2.12. 
 (c) Subject to the succeeding paragraph, every Security shall be subject to the restrictions on transfer provided in the Legend other than a Restricted
Global Security. Whenever any Restricted Security other than a Restricted Global Security is presented or surrendered for registration of transfer or for exchange for a Security registered in a name other than that of the Holder, such Security must
be accompanied by a certificate in substantially the form set forth in Exhibit A, dated the date of such surrender and signed by the Holder of such Security, as to compliance with such restrictions on transfer. The Registrar shall not be
required to accept for such registration of transfer or exchange any Security not so accompanied by a properly completed certificate. 
 (d)
The restrictions imposed by the Legend upon the transferability of any Security shall cease and terminate when such Security has been sold pursuant to an effective registration statement under the Securities Act or transferred in compliance with
Rule 144 under the Securities Act (or any successor provision thereto) or, if earlier, upon the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any successor provision). Any
Security as to which such restrictions on transfer shall have expired in accordance with their terms or shall have terminated may, upon a surrender of such Security for exchange to the Registrar in accordance with the provisions of this
Section 2.12 (accompanied, in the event that such restrictions on transfer have terminated by reason of a transfer in compliance with Rule 144 or any successor provision, by, if requested by the Company or the Registrar, an opinion of
counsel reasonably acceptable to the Company and addressed to the Company in form acceptable to the Company, to the effect that the transfer of such Security has been made in compliance with Rule 144 or 

  

 -15- 

 
such successor provision), be exchanged for a new Security, of like tenor and aggregate principal amount, which shall not bear the restrictive Legend. The
Company shall inform the Trustee of the effective date of any registration statement registering the Securities under the Securities Act. The Trustee shall not be liable for any action taken or omitted to be taken by it in good faith in accordance
with the aforementioned opinion of counsel or registration statement. 
 (e) As used in the preceding two paragraphs of this
Section 2.12, the term “transfer” encompasses any sale, pledge, transfer, hypothecation or other disposition of any Security. 
 (f) The provisions of clauses (i), (ii), (iii), (iv) and (v) below shall apply only to Global Securities: 
 (i) Notwithstanding any other provisions of this Indenture or the Securities, a Global Security shall not be exchanged in whole or in part for a Security registered in the name of any Person other than the Depositary or one or more nominees
thereof, provided that a Global Security may be exchanged for Securities registered in the names of any person designated by the Depositary in the event that (A) the Depositary has notified the Company that it is unwilling or
unable to continue as Depositary for such Global Security or such Depositary has ceased to be a “clearing agency” registered under the Exchange Act, and a successor Depositary is not appointed by the Company within 90 days,
(B) the Company has provided the Depositary with written notice that it has decided to discontinue use of the system of book-entry transfer through the Depositary or any successor Depositary or (C) an Event of Default has occurred and is
continuing with respect to the Securities. Any Global Security exchanged pursuant to clauses (A) or (B) above shall be so exchanged in whole and not in part, and any Global Security exchanged pursuant to clause (C) above may be
exchanged in whole or from time to time in part as directed by the Depositary. Any Security issued in exchange for a Global Security or any portion thereof shall be a Global Security; provided that any such Security so issued that is registered in
the name of a Person other than the Depositary or a nominee thereof shall not be a Global Security. 
 (ii) Securities issued
in exchange for a Global Security or any portion thereof shall be issued in definitive, fully registered form, without interest coupons, shall have an aggregate principal amount equal to that of such Global Security 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 the applicable legends provided for herein. Any Global Security to be exchanged in whole shall be surrendered by
the Depositary to the Trustee, as Registrar. With regard to any Global Security to be exchanged in part, either such Global Security shall be so surrendered for exchange or, if the Trustee is acting as custodian for the Depositary or its nominee
with respect to such Global Security, the principal amount thereof shall be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the Trustee. Upon any such surrender or
adjustment, the Trustee shall authenticate and deliver the Security issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof. 
 (iii) Subject to the provisions of clause (v) below, the registered Holder may grant proxies and otherwise authorize any Person,
including Agent Members and persons that may hold interests through Agent Members, to take any action which a Holder is entitled to take under this Indenture or the Securities. 
  

 -16- 

 (iv) In the event of the occurrence of any of the events specified in clause (i)
above, the Company will promptly make available to the Trustee a reasonable supply of Certificated Securities in definitive, fully registered form, without interest coupons. 
 (v) Neither 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 Security registered in the name of the Depositary or any nominee thereof, or under any such Global Security, 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 Security 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 Security. 
 SECTION 2.13. CUSIP NUMBERS.
 The Company in issuing the Securities may use one or more “CUSIP” numbers (if
then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of purchase as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of
such numbers either as printed on the Securities or as contained in any notice of a purchase and that reliance may be placed only on the other identification numbers printed on the Securities, and any such purchase shall not be affected by any
defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the “CUSIP” numbers. 
 SECTION 2.14. WITHHOLDING TAXES.
 The Company or any agent of the Company shall be entitled to deduct and withhold
amounts required to be deducted and withheld under the Internal Revenue Code of 1986, as amended, or any provision of any federal, state, local or foreign tax law. To the extent that amounts are so deducted and withheld, such deducted and withheld
amounts shall be treated for all purposes of this Indenture as having been paid to such holder in respect of whom such deduction and withholding was made. 
 ARTICLE 3 
 PURCHASE OF SECURITIES AT OPTION OF THE HOLDER UPON DESIGNATED EVENT 
 SECTION 3.1. [Reserved].
 SECTION 3.2. PURCHASE OF SECURITIES AT OPTION OF THE HOLDER UPON DESIGNATED EVENT.
 (a) If at any time that Securities
remain outstanding there shall occur a Designated Event, Securities not theretofore called for redemption shall be purchased by the Company at the option of the Holders, as of the date that is 30 Business Days after the occurrence of the
Designated Event (the “Designated Event Purchase Date”) at a purchase price equal to 100% of the principal amount of the Securities to be repurchased, together with accrued and unpaid interest (including any Additional Interest and/or
Extension 

  

 -17- 

 
Fee), if any, to, but excluding, the Designated Event Purchase Date (the “Designated Event Purchase Price”), subject to satisfaction by or on
behalf of any Holder of the requirements set forth in subsection (c) of this Section 3.2. 
 A “Change in Control” shall
be deemed to have occurred if any of the following occurs after the date hereof: 
 (1) any “person” or “group” (as such
terms are defined below) is or becomes the “beneficial owner” (as defined below), directly or indirectly, of shares of Voting Stock of the Company representing 50% or more of the total voting power of all outstanding Voting Stock of the
Company or has the power, directly or indirectly, to elect a majority of the members of the Board of Directors of the Company; or 
 (2) the
Company consolidates with, or merges with or into, another Person or the Company sells, assigns, conveys, transfers, leases or otherwise disposes of all or substantially all of the assets of the Company, or any Person consolidates with, or merges
with or into, the Company, in any such event other than pursuant to a transaction in which the Persons that “beneficially owned” (as defined below), directly or indirectly, shares of Voting Stock of the Company immediately prior to such
transaction “beneficially own” (as defined below), directly or indirectly, shares of Voting Stock of the Company representing at least a majority of the total voting power of all outstanding Voting Stock of the surviving or transferee
Person; 
 (3) the holders of capital stock of the Company approve any plan or proposal for the liquidation or dissolution of the Company
(whether or not otherwise in compliance with the terms hereof); or 
 (4) any time the Continuing Directors do not constitute a majority of
the Board of Directors. 
 For the purpose of the definition of “Change in Control,” (i) “person” and “group” have the
meanings given such terms under Section 13(d) and 14(d) of the Exchange Act or any successor provision to either of the foregoing, and the term “group” includes any group acting for the purpose of acquiring, holding or disposing of
securities within the meaning of Rule 13d-5(b)(1) under the Exchange Act (or any successor provision thereto), (ii) a “beneficial owner” shall be determined in accordance with Rule 13d-3 under the Exchange Act, as in effect
on the date of this Indenture, except that the number of shares of Voting Stock of the Company shall be deemed to include, in addition to all outstanding shares of Voting Stock of the Company and Unissued Shares deemed to be held by the
“person” or “group” (as such terms are defined above) or other Person with respect to which the Change in Control determination is being made, all Unissued Shares deemed to be held by all other Persons, and (iii) the terms
“beneficially owned” and “beneficially own” shall have meanings correlative to that of “beneficial owner.” The term “Unissued Shares” means shares of Voting Stock not outstanding that are subject to options,
warrants, rights to purchase or conversion privileges exercisable within 60 days of the date of determination of a Change in Control. 
 Notwithstanding anything to the contrary set forth in this Section 3.2, a Change in Control under (1) or (2) above will not be deemed to have occurred if in the case of a merger or consolidation, all of the consideration
(excluding cash payments for fractional shares and cash payments pursuant to dissenters’ appraisal rights) in the merger or consolidation constituting the Change in Control consists of common stock traded on a United States national securities
exchange or listed on the Nasdaq Global Market (or which will be so traded or listed when issued or exchanged in connection with such Change in Control) and as a result of such transaction or transactions the Securities become convertible solely
into such common stock. 
  

 -18- 

 (b) Within 10 Business Days after the occurrence of a Designated Event, the Company shall mail a written
notice of the Designated Event to the Trustee and to each Holder (and to beneficial owners as required by applicable law). The notice shall include the form of a Designated Event Purchase Notice to be completed by the Holder and shall state:

pursuant to Article 4 of this Indenture only to the extent that the Designated Event Purchase Notice has been withdrawn in accordance with the terms of this Indenture; 
 (10) the procedures that the Holder must follow to exercise rights under this Section 3.2; 
 (11) the procedures for withdrawing a Designated Event Purchase Notice, including a form of notice of withdrawal; and 
 (12) that the Holder must satisfy the requirements set forth in the Securities in order to convert the Securities. 
 If any of the Securities is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the
procedures of the Depositary applicable to the repurchase of Global Securities. 
 (c) A Holder may exercise its rights specified in
subsection (a) of this Section 3.2 upon delivery of a written notice (which shall be in substantially the form included in Exhibit A hereto and which may be delivered by letter, overnight courier, hand delivery, facsimile
transmission or in any other written form and, in the case of Global Securities, may be delivered electronically or by other means in accordance with the Depositary’s customary procedures) of the exercise of such rights (a “Designated
Event Purchase Notice”) to any Paying Agent at any time prior to the close of business on the Business Day next preceding the Designated Event Purchase Date. 
  

 -19- 

 The delivery of such Security to any Paying Agent (together with all necessary endorsements) at the
office of such Paying Agent shall be a condition to the receipt by the Holder of the Designated Event Purchase Price therefor. 
 The Company
shall purchase from the Holder thereof, pursuant to this Section 3.2, a portion of a Security if the principal amount of such portion is $1,000 or an integral multiple of $1,000. Provisions of the Indenture that apply to the purchase of all of
a Security pursuant to Sections 3.2 through 3.7 also apply to the purchase of such portion of such Security. 
 Notwithstanding anything
herein to the contrary, any Holder delivering to a Paying Agent the Designated Event Purchase Notice contemplated by this subsection (c) shall have the right to withdraw such Designated Event Purchase Notice in whole or in a portion thereof
that is a principal amount of $1,000 or in an integral multiple thereof at any time prior to the close of business on the Business Day next preceding the Designated Event Purchase Date by delivery of a written notice of withdrawal to the Paying
Agent in accordance with Section 3.3. 
 A Paying Agent shall promptly notify the Company of the receipt by it of any Designated Event
Purchase Notice or written withdrawal thereof. 
 Anything herein to the contrary notwithstanding, in the case of Global Securities, any
Designated Event Purchase Notice may be delivered or withdrawn and such Securities may be surrendered or delivered for purchase in accordance with the Applicable Procedures as in effect from time to time.

 Upon receipt by any Paying Agent of the Designated Event Purchase Notice specified in Section 3.2(c), the Holder of the Security in respect of which such Designated Event Purchase Notice was given shall (unless
such Designated Event Purchase Notice is withdrawn as specified below) thereafter be entitled to receive the Designated Event Purchase Price with respect to such Security. Such Designated Event Purchase Price shall be paid to such Holder promptly
following the later of (a) the Designated Event Purchase Date with respect to such Security (provided the conditions in Section 3.2(c) have been satisfied) and (b) the time of delivery of such Security to a Paying Agent by the
Holder thereof in the manner required by Section 3.2(c). Securities in respect of which a Designated Event Purchase Notice has been given by the Holder thereof may not be converted into shares of Common Stock pursuant to Article 4 on or
after the date of the delivery of such Designated Event Purchase Notice unless such Designated Event Purchase Notice has first been validly withdrawn. 
 A Designated Event Purchase Notice may be withdrawn by means of a written notice (which may be delivered by mail, overnight courier, hand delivery, facsimile transmission or in any other written form and, in the case
of Global Securities, may be delivered electronically or by other means in accordance with the Depositary’s customary procedures) of withdrawal delivered by the Holder to a Paying Agent at any time prior to the close of business on the Business
Day immediately preceding the Designated Event Purchase Date, specifying the principal amount of the Security or portion thereof (which must be a principal amount of $1,000 or an integral multiple of $1,000 in excess thereof) with respect to which
such notice of withdrawal is being submitted.

than the Company or an Affiliate of the Company) an amount of money (in immediately available funds if deposited on such Designated Event Purchase Date) sufficient to pay the aggregate Designated Event Purchase Price of all the Securities or
portions thereof that are to be purchased as of such Designated Event Purchase Date. The manner in which the deposit required by this Section 3.4 is made by the Company shall be at the option of the Company, provided that such
deposit shall be made in a manner such that the Trustee or a Paying Agent shall have immediately available funds on the Designated Event Purchase Date. 
 If a Paying Agent holds, in accordance with the terms hereof, money sufficient to pay the Designated Event Purchase Price of any Security for which a Designated Event Purchase Notice has been tendered and not
withdrawn in accordance with this Indenture then, on the Designated Event Purchase Date, such Security will cease to be outstanding and the rights of the Holder in respect thereof shall terminate (other than the right to receive the Designated Event
Purchase Price as aforesaid). The Company shall publicly announce the principal amount of Securities purchased as a result of such Designated Event on or as soon as practicable after the Designated Event Purchase Date. 
 SECTION 3.5. SECURITIES PURCHASED IN PART.
 Any Security that is to be purchased only in part shall be surrendered at the office of a Paying Agent, and promptly after the Designated Event Purchase Date the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities, of such authorized denomination or denominations as may be requested by such Holder, in aggregate principal amount equal to, and in
exchange for, the portion of the principal amount of the Security so surrendered that is not purchased. 
 SECTION 3.6. COMPLIANCE
WITH SECURITIES LAWS UPON PURCHASE OF SECURITIES.
 In connection with any offer to purchase or purchase of Securities under
Section 3.2, the Company shall (a) comply with Rule 13e-4 and Rule 14e-1 (or any successor to either such Rule), if applicable, under the Exchange Act, (b) file the related Schedule TO (or any successor or similar schedule,
form or report) if required under the Exchange Act, and (c) otherwise comply with all federal and state securities laws in connection with such offer to purchase or purchase of Securities, all so as to permit the rights of the Holders and
obligations of the Company under Sections 3.2 through 3.5 to be exercised in the time and in the manner specified therein. 
 SECTION 3.7. REPAYMENT TO THE COMPANY.
 To the extent that the aggregate amount of cash deposited by the Company
pursuant to Section 3.4 exceeds the aggregate Designated Event Purchase Price together with interest (including any Additional Interest and/or Extension Fee), if any, thereon of the Securities or portions thereof that the Company is obligated
to purchase, then promptly after the Designated Event Purchase Date the Trustee or a Paying Agent, as the case may be, shall return any such excess cash to the Company.

 (a) Subject to the obligation and the right of the Company to pay some or all of the conversion consideration in cash in accordance with Section 4.14
and the other provisions of this Article 4, and upon compliance with the provisions of this Indenture, each Holder shall have the right, at his or her option, at any time on or before the close of business on the last Trading Day prior to the
Maturity Date (except that, with respect to any Security or portion thereof subject to a redemption in accordance with Article 13 of this Indenture or a duly completed election for repurchase in connection with a Designated Event, such right shall
terminate at the close of business on the last Trading Day prior to the Redemption Date or Designated Event Purchase Date, as applicable (unless the Company defaults in the payment due upon such redemption or repurchase, as applicable, or such
Holder elects to withdraw the submission of such election to repurchase in accordance with Section 3.2(c))) to convert the principal amount of any Security held by such Holder, or any portion of such principal amount which is $1,000 or an
integral multiple thereof, into that number of fully paid and non-assessable shares of Common Stock obtained by dividing the principal amount of the Security or portion thereof to be converted by the Conversion Price in effect at such time, only
under the following circumstances: 
 (1) during any calendar quarter beginning after March 31, 2007, and only during such calendar
quarter, if, as of the last day of the immediately preceding calendar quarter, the Volume Weighted Average Price per share of the Common Stock for at least 20 Trading Days in the period of the 30 consecutive Trading Days ending on the last Trading
Day of such preceding calendar quarter was more than 150% of the Conversion Price on the last day of such preceding calendar quarter (the “Conversion Trigger Price”); 
 (2) during any five Trading Day period after any five consecutive Trading Day period in which the Trading Price per $1,000 principal amount of
Securities, as determined following a request by a holder in accordance with the procedures described below in Section 4.1(d)(2), for each day of that period was less than 98% of the product of (x) the Volume Weighted Average Price of the
Common Stock for each day in that period and (y) the Conversion Rate per $1,000 principal amount of Securities; 
 (3) if the Company
distributes to all holders of Common Stock rights or warrants entitling them to purchase, for a period expiring within 45 days of the date of issuance, Common Stock at less than the Closing Price of the Common Stock on the day of issuance;

 (4) if the Company distributes to all holders of Common Stock, assets, debt securities or rights to purchase the Company’s
securities, which distribution has a per share value exceeding 7.5% of the Volume Weighted Average Price of the Common Stock on the Business Day preceding the declaration date for such distribution; 
 (5) if a Designated Event occurs or is anticipated to occur (as further described in clause (h)); 
 (6) at any time during the period beginning 60 days prior to, but excluding, any scheduled Designated Event Purchase Date or the Final Maturity Date; or

  

 -22- 

 (7) for Securities that have been called for redemption, at any time prior to the close of business on
the Business Day prior to the Redemption Date, even if the Securities are not otherwise convertible at such time. 
 (b) In the case of a
distribution contemplated by clauses (3) and (4) of Section 4.1(a), the Company shall notify Holders at least 20 days prior to the ex-dividend date for such distribution (the “Distribution Notice”). Once the Company has
given the Distribution Notice, Holders may surrender their Securities for conversion at any time until the earlier of the close of business on the last Trading Day preceding the ex-dividend date or the Company’s announcement that such
distribution will not take place. In the event of a distribution contemplated by clauses (3) and (4) of Section 4.1(a), Holders may not convert the Securities if the Holders will otherwise participate in such distribution without
converting their Securities. The Company will provide written notice to the Conversion Agent as soon as reasonably practicable of any anticipated or actual event or transaction that will cause or causes the Securities to become convertible pursuant
to clauses (3) or (4) of Section 4.1(a). 
 (c) In the case of a transaction contemplated by clause (5) of
Section 4.1(a) that the Company knows or reasonably should know will occur, the Company will notify the Holders and Trustee at least 15 Trading Days prior to the date on which such Designated Event becomes effective (the “Designated Event
Date”). If the Company does not know, and should not reasonably know, that a Designated Event will occur until a date that is within 15 Trading Days before the anticipated Designated Event Date or other applicable event, the Company will notify
the Holders and the Trustee promptly after the Company has knowledge of such Designated Event or such other event. Holders may surrender Securities for conversion at any time beginning 15 Trading Days before the anticipated Designated Event Purchase
Date of a Designated Event and until the Trading Day prior to the date of the Designated Event Purchase Date. 
 (d)(1) For each calendar
quarter of the Company, beginning with the calendar quarter beginning at any time after March 31, 2007, the Conversion Agent, on behalf of the Company, will determine, on the first Business Day following the last Trading Day of the previous
calendar quarter, whether the Securities are convertible pursuant to clause (1) of Section 4.1(a), and, if so, will notify the Trustee and the Company in writing. Upon request of the Conversion Agent, the Company shall provide, or cause to
be provided to, the Conversion Agent the Volume Weighted Average Price per share of Common Stock for the 30 consecutive Trading Days ending on the last Trading Day of the preceding calendar quarter. 
 (2) The Bid Solicitation Agent shall have no obligation to determine the Trading Price of the Securities and whether the Securities are convertible
pursuant to clause (2) of Section 4.1(a) unless the Company has requested such determination in writing; and the Company shall have no obligation to make such request unless a Holder of Securities provides the Company with reasonable
evidence that the Trading Price per $1,000 principal amount of Securities would be less than 98% of the product of the Volume Weighted Average Price of the Common Stock and the Conversion Rate per $1,000 principal amount of Securities. At such time,
the Company shall instruct the Bid Solicitation Agent to determine the Trading Price of the Securities beginning on the next Trading Day and on each successive Trading Day until the Trading Price per $1,000 principal amount of the Securities is
greater than 98% of the product of the Volume Weighted Average Price of the Common Stock and the Conversion Rate per $1,000 principal amount of the Securities. 
 (e) The conversion rights pursuant to this Article 4 shall commence on the initial issuance date of the Securities and expire at the close of business on the Business Day immediately preceding the Final Maturity Date,
but shall be exercisable only during the time periods specified with respect to each 

  

 -23- 

 
circumstance pursuant to which the Securities become convertible. If a Security is called for redemption pursuant to Article 13 or submitted or presented for
purchase upon a Designated Event pursuant to Section 3.2, such conversion right shall terminate at the close of business on the Business Day immediately preceding the Redemption Date or Designated Event Purchase Date, as applicable, for such
Security (unless the Company shall default in the payment due upon such redemption or repurchase, as applicable, in which case the conversion right shall terminate at the close of business on the date such failure is cured and such Security is
redeemed or purchased). If a Security is convertible as a result of a Designated Event such conversion right shall commence and terminate as set forth in Section 4.1(c). Securities in respect of which a Designated Event Purchase Notice has been
delivered may not be surrendered for conversion pursuant to this Article 4 prior to a valid withdrawal of such Designated Event Purchase Notice in accordance with the provisions of Section 3.2(c). 
 (f) Provisions of this Indenture that apply to conversion of all of a Security also apply to conversion of a portion of a Security. 
 (g) A Holder of Securities is not entitled to any rights of a holder of Common Stock until such holder has converted its Securities into Common Stock,
and only to the extent such Securities are deemed to have been converted into Common Stock pursuant to this Article 4. 
 (h) If there shall
have occurred a Designated Event, then the Conversion Rate per $1,000 principal amount of Securities otherwise in effect in respect of Securities for which a conversion notice is received by the Conversion Agent during the period beginning 15
Trading Days before the date announced by the Company as the anticipated Designated Event Date and ending at the close of business on the Trading Day immediately preceding the Designated Event Purchase Date shall be increased by the amount, if any,
determined by reference to the table below, based on the Designated Event Date and the Stock Price of such Designated Event; provided that if the Stock Price or Designated Event Date are not set forth on the table: (i) if the actual Stock Price
on the Designated Event Date is between two Stock Prices on the table or the actual Designated Event Date is between two Designated Event Dates on the table, the amount of the Conversion Rate adjustment will be determined by a straight-line
interpolation between the adjustment amounts set forth for the two Stock Prices and the two Designated Event Dates on the table based on a 365-day year, as applicable, (ii) if the Stock Price on the Designated Event Date exceeds $31.00 per
share, subject to adjustment as set forth herein, no adjustment to the applicable Conversion Rate will be made, and (iii) if the Stock Price on the Designated Event Date is less than $11.00 per share, subject to adjustment as set forth herein,
no adjustment to the applicable Conversion Rate will be made. If holders of the Common Stock receive only cash in the Designated Event, the Stock Price shall be the cash amount paid per share of the Common Stock in connection with the Designated
Event. Otherwise, the Stock Price shall be equal to the Volume Weighted Average Price of the Common Stock for each of the 10 Trading Days immediately preceding, but not including, the applicable Designated Event Date. 
 The following table shows the amount, if any, by which the applicable Conversion Rate will increase for each Stock Price and Designated Event Date set
forth below:

 The Stock Prices set forth in the first column of the table above will be adjusted as of any date
on which the Conversion Rate of the Securities is adjusted. The adjusted Stock Prices will equal the Stock Prices applicable immediately prior to such adjustment multiplied by a fraction, the numerator of which is the Conversion Rate immediately
prior to the adjustment giving rise to the Stock Price adjustment and the denominator of which is the Conversion Rate as so adjusted. The Conversion Rate adjustment amounts set forth in the table above will be adjusted in the same manner as the
Conversion Rate as set forth in Section 4.6 hereof, other than as a result of an adjustment of the Conversion Rate by virtue of the provisions of this Section 4.1(h). 
 Notwithstanding the foregoing, in no event will the Conversion Rate exceed 88.6667 per $1,000 principal amount of Securities, other than on account
of proportional adjustments to the Conversion Rate in the manner set forth in Section 4.6 below. 
 (i) Except as set forth in
Section 4.2, by delivering the amount of cash and, if applicable, the number of shares of Common Stock issuable on conversion to the Trustee, the Company will be deemed to have satisfied its obligation to pay the principal amount of the
Securities so converted and its obligation to pay accrued and unpaid interest attributable to the period from the most recent Interest Payment Date through the Conversion Date (which amount will be deemed paid in full rather than cancelled,
extinguished or forfeited). 
 (j) If a Holder has delivered a Notice that it wishes to have its Securities repurchased in accordance with
Section 3.2, the Holder may not surrender such Security for conversion until the holder has withdrawn such notice in accordance with Section 3.2(c). 
 SECTION 4.2. CONVERSION PROCEDURE.
 To convert a Security, a Holder must (a) complete and
manually sign the conversion notice on the back of the Security and deliver such notice to a Conversion Agent, (b) surrender the Security to a Conversion 

  

 -25- 

 
Agent, (c) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, and (d) pay any transfer or
similar tax, if required. The date on which the Holder satisfies all of those requirements is the “Conversion Date.” As soon as practicable after the later of the Conversion Date and the date all calculations necessary to make such payment
and delivery have been made, but in no event later than five Trading Days after the later of such dates, the Company shall (i) pay to the Holders the cash in respect of any fractional interest in respect of a share of Common Stock arising upon
such conversion and, if exercised by the Company, in respect of Section 4.14 and (ii) issue and shall deliver to such Holder at the office or agency maintained by the Company for such purpose, a certificate or certificates for the number
of whole shares of Common Stock issuable upon the conversion. Anything herein to the contrary notwithstanding, in the case of Global Securities, conversion notices may be delivered and such Securities may be surrendered for conversion in accordance
with the Applicable Procedures as in effect from time to time. 
 The person in whose name the Common Stock certificate is registered shall
be deemed to be a stockholder of record on the Conversion Date; provided, however, that no surrender of a Security on any date when the stock transfer books of the Company shall be closed shall be effective to constitute the person or
persons entitled to receive the shares of Common Stock upon such conversion as the record holder or holders of such shares of Common Stock on such date, but such surrender shall be effective to constitute the person or persons entitled to receive
such shares of Common Stock as the record holder or holders thereof for all purposes at the close of business on the next succeeding day on which such stock transfer books are open; provided, further, that such conversion shall be at
the Conversion Price in effect on the Conversion Date as if the stock transfer books of the Company had not been closed. Upon conversion of a Security, such person shall no longer be a Holder of such Security. No payment or adjustment will be made
for dividends or distributions on shares of Common Stock issued upon conversion of a Security. 
 Securities so surrendered for conversion
(in whole or in part) during the period from the close of business on any Record Date to the opening of business on the next succeeding Interest Payment Date, if any (excluding Securities or portions thereof presented for purchase upon a Designated
Event on a Designated Event Purchase Date during the period beginning at the close of business on a Record Date and ending at the opening of business on the first Business Day after the next succeeding Interest Payment Date, if any, or if such
Interest Payment Date, if any, is not a Business Day, the second such Business Day) shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest (including any Additional Interest and/or Extension Fee),
if any, payable on such Interest Payment Date on the principal amount of such Security then being converted, and such interest (including any Additional Interest and/or Extension Fee), if any, shall be payable to such registered Holder
notwithstanding the conversion of such Security, subject to the provisions of this Indenture relating to the payment of defaulted interest, if any, by the Company. Except as otherwise provided in this Section 4.2, no payment or adjustment will
be made for accrued interest (including any Additional Interest and/or Extension Fee), if any, on a converted Security. If the Company defaults in the payment of interest (including any Additional Interest and/or Extension Fee), if any, payable on
such Interest Payment Date, the Company shall promptly repay such funds to such Holder. 
 Nothing in this Section shall affect the
right of a Holder in whose name any Security is registered at the close of business on a record date to receive the interest (including any Additional Interest and/or Extension Fee), if any, payable on such Security on the related Interest Payment
Date, if any, in accordance with the terms of this Indenture, the Securities and the Registration Rights Agreement. If a Holder converts more than one Security at the same time, the number of shares of Common Stock issuable upon the conversion shall
be based on the aggregate principal amount of Securities converted. 
  

 -26- 

 Upon surrender of a Security that is converted in part, the Company shall execute, and the Trustee shall
authenticate and deliver to the Holder, a new Security equal in principal amount to the unconverted portion of the Security surrendered. 
 Upon the Company’s determination that a holder is or will be entitled to convert its Securities into cash and, if applicable, shares of Common Stock pursuant to this Article 4, the Company will promptly notify such Holder in the manner
provided in Section 12.2 of this Indenture. 
 SECTION 4.3. FRACTIONAL SHARES.
 The Company will not issue fractional shares of Common Stock upon conversion of Securities. In lieu
thereof, the Company will pay an amount in cash for the current market value of the fractional shares. The current market value of a fractional share shall be determined, (calculated to the nearest 1/1000th of a share) by multiplying the Closing Price (determined as set forth in Section 4.6(d)) of the Common Stock on the Trading Day immediately prior to the
Conversion Date by such fractional share and rounding the product to the nearest whole cent. 
 SECTION 4.4. TAXES ON
CONVERSION.
 If a Holder converts a Security, the Company shall pay any documentary, stamp or similar issue or transfer tax due on the
issue of shares of Common Stock upon such conversion. However, the Holder shall pay any such tax which is due because the Holder requests the shares to be issued in a name other than the Holder’s name. The Conversion Agent may refuse to deliver
the certificate representing the Common Stock being issued in a name other than the Holder’s name until the Conversion Agent receives a sum sufficient to pay any tax which will be due because the shares are to be issued in a name other than the
Holder’s name. Nothing herein shall preclude any tax withholding required by law or regulation. 
 SECTION 4.5. COMPANY TO
PROVIDE STOCK.
 The Company shall, prior to issuance of any Securities hereunder, and from time to time as may be necessary, reserve, out
of its authorized but unissued Common Stock, a sufficient number of shares of Common Stock to permit the conversion of all outstanding Securities into shares of Common Stock. 
 All shares of Common Stock delivered upon conversion of the Securities shall be newly issued shares, shall be duly authorized, validly issued, fully paid
and nonassessable and shall be free from preemptive or similar rights and free of any lien or adverse claim. 
 The Company will endeavor
promptly to comply with all federal and state securities laws regulating the offer and delivery of shares of Common Stock upon conversion of Securities, if any, and will list or cause to have quoted such shares of Common Stock on each national
securities exchange or on the Nasdaq Global Market or other over-the-counter market or such other market on which the Common Stock is then listed or quoted; provided, however, that if rules of such automated quotation system or
exchange permit the Company to defer the listing of such Common Stock until the first conversion of the Securities into Common Stock in accordance with the provisions of this Indenture, the Company covenants to list such Common Stock issuable upon
conversion of the Securities in accordance with the requirements of such automated quotation system or exchange at such time. Any Common Stock issued upon conversion of a Security hereunder which at the time of conversion was a Restricted Security
will also be a Restricted Security. 
  

 -27- 

 SECTION 4.6. ADJUSTMENT OF CONVERSION PRICE.
 The conversion price as stated in paragraph 6 of the Securities (the “Conversion Price”) shall be adjusted from time to time by the Company
as follows: 
 (a) In case the Company shall (i) pay a dividend on its Common Stock in shares of Common Stock, (ii) make a
distribution on its Common Stock in shares of Common Stock, (iii) subdivide its outstanding Common Stock into a greater number of shares, or (iv) combine its outstanding Common Stock into a smaller number of shares, the Conversion Price in
effect immediately prior thereto shall be adjusted so that the Holder of any Security thereafter surrendered for conversion shall be entitled to receive that number of shares of Common Stock which it would have owned had such Security been converted
immediately prior to the happening of such event. An adjustment made pursuant to this subsection (a) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after
the effective date in the case of subdivision or combination. 
 (b) In case the Company shall issue rights or warrants to all or
substantially all holders of its Common Stock entitling them (for a period of not more than 60 days after such issuance) to subscribe for or purchase shares of Common Stock (or securities convertible into Common Stock) at a price per share (or
having a Conversion Price per share) less than the Current Market Price per share of Common Stock (as determined in accordance with subsection (f) of this Section 4.6) on the record date for the determination of stockholders entitled to
receive such rights or warrants, the Conversion Price in effect immediately prior thereto shall be adjusted so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to such record date by a
fraction of which the numerator shall be the number of shares of Common Stock outstanding on such record date plus the number of shares which the aggregate offering price of the total number of shares of Common Stock so offered (or the aggregate
conversion price of the convertible securities so offered, which shall be determined by multiplying the number of shares of Common Stock issuable upon conversion of such convertible securities by the conversion price per share of Common Stock
pursuant to the terms of such convertible securities) would purchase at the Current Market Price per share (as defined in subsection (f) of this Section 4.6) of Common Stock on such record date, and of which the denominator shall be the
number of shares of Common Stock outstanding on such record date plus the number of additional shares of Common Stock offered (or into which the convertible securities so offered are convertible). Such adjustment shall be made successively whenever
any such rights or warrants are issued, and shall become effective immediately after such record date. If at the end of the period during which such rights or warrants are exercisable not all rights or warrants shall have been exercised, the
adjusted Conversion Price shall be immediately readjusted to what it would have been based upon the number of additional shares of Common Stock actually issued (or the number of shares of Common Stock issuable upon conversion of convertible
securities actually issued). 
 (c) In case the Company shall distribute to all or substantially all holders of its Common Stock any shares
of capital stock of the Company (other than Common Stock), evidences of indebtedness or other non-cash assets (including securities of any person other than the Company but excluding (1)dividends or distributions paid exclusively in cash or
(2)dividends or distributions referred to in subsection(a) of this Section4.6), or shall distribute to all or substantially all holders of its Common Stock rights or warrants to subscribe for or purchase any of its securities (excluding those rights
and warrants referred to in subsection(b) of this Section4.6 and also excluding the distribution of rights to all holders of Common Stock pursuant to a Rights Plan (as defined below) adopted before or after the date of this Indenture), then in each
such case the Conversion Price shall be adjusted so that the same shall equal the price determined by multiplying the current Conversion Price by a fraction of which the numerator shall be the Current Market 

  

 -28- 

 
Price per share (as defined in subsection (f) of this Section 4.6) of the Common Stock on the record date mentioned below less the fair market value on
such record date (as determined by the Board of Directors, whose determination shall be conclusive evidence of such fair market value and which shall be evidenced by an Officers’ Certificate delivered to the Trustee) of the portion of the
capital stock, evidences of indebtedness or other non-cash assets so distributed or of such rights or warrants applicable to one share of Common Stock (determined on the basis of the number of shares of Common Stock outstanding on the record date),
and of which the denominator shall be the Current Market Price per share (as defined in subsection (f) of this Section 4.6) of the Common Stock on such record date. Such adjustment shall be made successively whenever any such distribution is made
and shall become effective immediately after the record date for the determination of stockholders entitled to receive such distribution. 
 In the event the then fair market value (as so determined) of the portion of the capital stock, evidences of indebtedness or other non-cash assets so distributed or of such rights or warrants applicable to one share of Common Stock is equal
to or greater than the Current Market Price per share of the Common Stock on such record date, in lieu of the foregoing adjustment, adequate provision shall be made so that each holder of a Security shall have the right to receive upon conversion
the amount of capital stock, evidences of indebtedness or other non-cash assets so distributed or of such rights or warrants such holder would have received had such holder converted each Security on such record date. In the event that such dividend
or distribution is not so paid or made, the Conversion Price shall again be adjusted to be the Conversion Price which would then be in effect if such dividend or distribution had not been declared. If the Board of Directors determines the fair
market value of any distribution for purposes of this Section 4.6(c) by reference to the actual or when issued trading market for any securities, it must in doing so consider the prices in such market over the same period used in computing the
Current Market Price of the Common Stock. 
 With respect to any rights (the “Rights”) that may be issued or distributed pursuant
to any rights plan that the Company implements after the date of this Indenture (any Rights that may be issued pursuant to any such future rights plan being referred to as, a “Rights Plan”), upon conversion of the Securities into Common
Stock, to the extent that such Rights Plan is in effect upon such conversion, the holders of Securities will receive, in addition to the Common Stock, the Rights described therein (whether or not the Rights have separated from the Common Stock at
the time of conversion), subject to the limitations set forth in any such Rights Plan. Any distribution of rights or warrants pursuant to a Rights Plan complying with the requirements set forth in the immediately preceding sentence of this paragraph
shall not constitute a distribution of rights or warrants pursuant to this Section 4.6(c). 
 Rights or warrants (other than rights
issued pursuant to a Rights Plan) distributed by the Company to all holders of Common Stock entitling the holders thereof to subscribe for or purchase shares of the Company’s Capital Stock (either initially or under certain circumstances),
which rights or warrants, until the occurrence of a specified event or events (“Trigger Event”): (i) are deemed to be transferred with such shares of Common Stock; (ii) are not exercisable; and (iii) are also issued in
respect of future issuances of Common Stock, shall be deemed not to have been distributed for purposes of this Section 4.6 (and no adjustment to the Conversion Price under this Section 4.6 will be required) until the occurrence of the
earliest Trigger Event, whereupon such rights and warrants shall be deemed to have been distributed and an appropriate adjustment (if any is required) to the Conversion Price shall be made under this Section 4.6(c). If any such right or
warrant, including any such existing rights or warrants distributed prior to the date of this Indenture, are subject to events, upon the occurrence of which such rights or warrants become exercisable to purchase different securities, evidences of
indebtedness or other assets, then the date of the occurrence of any and each such event shall be deemed to be the date of distribution and record date with respect to new rights or warrants with such rights (and a termination or expiration of the
existing rights or warrants without exercise 

  

 -29- 

 
by any of the holders thereof). In addition, in the event of any distribution (or deemed distribution) of rights or warrants, or any Trigger Event or other
event (of the type described in the preceding sentence) with respect thereto that was counted for purposes of calculating a distribution amount for which an adjustment to the Conversion Price under this Section 4.6 was made, (1) in the
case of any such rights or warrants which shall all have been redeemed or repurchased without exercise by any holders thereof, the Conversion Price shall be readjusted upon such final redemption or repurchase to give effect to such distribution or
Trigger Event, as the case may be, as though it were a cash distribution, equal to the per share redemption or repurchase price received by a holder or holders of Common Stock with respect to such rights or warrants (assuming such holder had
retained such rights or warrants), made to all holders of Common Stock as of the date of such redemption or repurchase, and (2) in the case of such rights or warrants which shall have expired or been terminated without exercise by any holders
thereof, the Conversion Price shall be readjusted as if such rights and warrants had not been issued. 
 (d) In case the Company shall, by
dividend or otherwise, at any time distribute (a “Triggering Distribution”) to all or substantially all holders of its Common Stock cash, the Conversion Price shall be reduced so that the same shall equal the price determined by
multiplying such Conversion Price in effect immediately prior to the open of business on the day on which such Triggering Distribution is declared by the Company (the “Determination Date”) by a fraction of which the numerator shall be the
Current Market Price per share of the Common Stock (as determined in accordance with subsection (f) of this Section 4.6) on the Determination Date less the sum of the aggregate amount of cash and the aggregate fair market value (determined
as aforesaid in this Section 4.6(d)) of any such other consideration so distributed, paid or payable (including, without limitation, the Triggering Distribution) applicable to one share of Common Stock (determined on the basis of the number of
shares of Common Stock outstanding on the Determination Date) and the denominator shall be such Current Market Price per share of the Common Stock (as determined in accordance with subsection (f) of this Section 4.6) on the Determination
Date, such reduction to become effective immediately prior to the opening of business on the day following the date on which the Triggering Distribution is paid. 
 (e) In case any tender offer made by the Company or any of its Subsidiaries for Common Stock shall expire and such tender offer (as amended upon the expiration thereof), then, immediately prior to the opening of
business on the day after the last date (the “Expiration Date”) tenders could have been made pursuant to such tender offer (as it may be amended) (the last time at which such tenders could have been made on the Expiration Date is
hereinafter sometimes called the “Expiration Time”), the Conversion Price shall be reduced so that the same shall equal the price determined by multiplying the Conversion Price in effect immediately prior to the close of business on the
Expiration Date by a fraction of which the numerator shall be the product of the number of shares of Common Stock outstanding (including tendered shares but excluding any shares held in the treasury of the Company) at the Expiration Time multiplied
by the Current Market Price per share of the Common Stock (as determined in accordance with subsection (f) of this Section 4.6) on the Trading Day next succeeding the Expiration Date and the denominator shall be the sum of (x) the
aggregate consideration (determined as aforesaid) payable to stockholders based on the acceptance (up to any maximum specified in the terms of the tender offer) of all shares validly tendered and not withdrawn as of the Expiration Time (the shares
deemed so accepted, up to any such maximum, being referred to as the “Purchased Shares”) and (y) the product of the number of shares of Common Stock outstanding (less any Purchased Shares and excluding any shares held in the treasury
of the Company) at the Expiration Time and the Current Market Price per share of Common Stock (as determined in accordance with subsection (f) of this Section 4.6) on the Trading Day next succeeding the Expiration Date, such reduction to
become effective immediately prior to the opening of business on the day following the Expiration Date. In the event that the Company is obligated to purchase shares pursuant to any such tender offer, but the Company is permanently 

  

 -30- 

 
prevented by applicable law from effecting any or all such purchases or any or all such purchases are rescinded, the Conversion Price shall again be adjusted
to be the Conversion Price which would have been in effect based upon the number of shares actually purchased. If the application of this Section 4.6(e) to any tender offer would result in an increase in the Conversion Price, no adjustment
shall be made for such tender offer under this Section 4.6(e). 
 For purposes of this Section 4.6(e), the term “tender
offer” shall mean and include both tender offers and exchange offers, all references to “purchases” of shares in tender offers (and all similar references) shall mean and include both the purchase of shares in tender offers and the
acquisition of shares pursuant to exchange offers, and all references to “tendered shares” (and all similar references) shall mean and include shares tendered in both tender offers and exchange offers. 
 (f) For the purpose of any computation under subsections (b), (c), (d) and (e) of this Section 4.6, the current market price (the
“Current Market Price”) per share of Common Stock on any date shall be deemed to be the average of the daily closing prices for the 30 consecutive Trading Days commencing 45 Trading Days before (i) the Determination Date or
the Expiration Date, as the case may be, with respect to distributions or tender offers under subsection (c) of this Section 4.6 or (ii) the record date with respect to distributions, issuances or other events requiring such
computation under subsection (b), (c), (d) or (e) of this Section 4.6. The closing price (the “Closing Price”) for each day shall be the last reported sales price or, in case no such reported sale takes place on such
date, the average of the reported closing bid and asked prices in either case on the Nasdaq Global Market or, if the Common Stock is not listed or admitted to trading on the Nasdaq Global Market, on the principal national securities exchange on
which the Common Stock is listed or admitted to trading or, if not listed or admitted to trading on the Nasdaq Global Market or any other national securities exchange, the closing sales price or, in case no reported sale takes place, the average of
the closing bid and asked prices, as furnished by any two members of the National Association of Securities Dealers, Inc. selected from time to time by the Company for that purpose. If no such prices are available, the Current Market Price per share
shall be the fair value of a share of Common Stock as determined in good faith by the Board of Directors (which shall be evidenced by an Officers’ Certificate delivered to the Trustee). 
 (g) In any case in which this Section 4.6 shall require that an adjustment be made following a record date or a Determination Date or Expiration
Date, as the case may be, established for purposes of this Section 4.6, the Company may elect to defer (but only until five Business Days following the filing by the Company with the Trustee of the certificate described in Section 4.9)
issuing to the Holder of any Security converted after such record date or Determination Date or Expiration Date the shares of Common Stock and other capital stock of the Company issuable upon such conversion over and above the shares of Common Stock
and other capital stock of the Company issuable upon such conversion only on the basis of the Conversion Price prior to adjustment; and, in lieu of the shares the issuance of which is so deferred, the Company shall issue or cause its transfer agents
to issue due bills or other appropriate evidence prepared by the Company of the right to receive such shares. If any distribution in respect of which an adjustment to the Conversion Price is required to be made as of the record date or Determination
Date or Expiration Date therefor is not thereafter made or paid by the Company for any reason, the Conversion Price shall be readjusted to the Conversion Price which would then be in effect if such record date had not been fixed or such effective
date or Determination Date or Expiration Date had not occurred. 
 SECTION 4.7. NO ADJUSTMENT.
 No adjustment in the Conversion Price shall be required if Holders may participate in the transactions set forth in Section 4.6 above without
converting. 
  

 -31- 

 No adjustment in the Conversion Price shall be required unless the adjustment would require an increase
or decrease of at least 1% in the Conversion Price as last adjusted; provided, however, that any adjustments which by reason of this Section 4.7 are not required to be made shall be carried forward and taken into account in any
subsequent adjustment. All calculations under this Article 4 shall be made to the nearest cent or to the nearest one-hundredth of a share, as the case may be. 
 No adjustment need be made for issuances of Common Stock pursuant to a Company plan for reinvestment of dividends or interest or for a change in the par value or a change to no par value of the Common Stock.

 To the extent that the Securities become convertible into the right to receive cash, no adjustment need be made thereafter as to the cash.
Interest will not accrue on the cash. 
 SECTION 4.8. ADJUSTMENT FOR TAX PURPOSES.
 The Company shall be entitled to make such reductions in the Conversion Price, in addition to those required by Section 4.6, as it in its discretion
shall determine to be advisable in order that any stock dividends, subdivisions of shares, distributions of rights to purchase stock or securities or distributions of securities convertible into or exchangeable for stock hereafter made by the
Company to its stockholders shall not be taxable. 
 SECTION 4.9. NOTICE OF ADJUSTMENT.
 Whenever the Conversion Price or conversion privilege is adjusted, the Company shall promptly mail to Holders a notice of the adjustment and file with the
Trustee an Officers’ Certificate briefly stating the facts requiring the adjustment and the manner of computing it. Unless and until the Trustee shall receive an Officers’ Certificate setting forth an adjustment of the Conversion Price,
the Trustee may assume without inquiry that the Conversion Price has not been adjusted and that the last Conversion Price of which it has knowledge remains in effect. 
 SECTION 4.10. NOTICE OF CERTAIN TRANSACTIONS.
 In the event that: 
 (1) the Company takes any action which would require an adjustment in the Conversion Price; 
 (2) the Company consolidates or merges with, or transfers all or substantially all of its property and assets to, another corporation and stockholders of
the Company must approve the transaction; or 
 (3) there is a dissolution or liquidation of the Company, 
 the Company shall mail to Holders and file with the Trustee a notice stating the proposed record or effective date, as the case may be. The Company shall mail the notice
at least ten days before such date. Failure to mail such notice or any defect therein shall not affect the validity of any transaction referred to in clause (1), (2) or (3) of this Section 4.10. 
  

 -32- 

 SECTION 4.11. EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE ON CONVERSION
PRIVILEGE.
 If any of the following shall occur, namely: (a) any reclassification or change of shares of Common Stock issuable upon
conversion of the Securities (other than a change in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination, or any other change for which an adjustment is provided in
Section 4.6); (b) any consolidation or merger or combination to which the Company is a party other than a merger in which the Company is the continuing corporation and which does not result in any reclassification of, or change (other than
in par value, or from par value to no par value, or from no par value to par value, or as a result of a subdivision or combination) in, outstanding shares of Common Stock; or (c) any sale or conveyance as an entirety or substantially as an
entirety of the property and assets of the Company, directly or indirectly, to any person, then the Company, or such successor, purchasing or transferee corporation, as the case may be, shall, as a condition precedent to such reclassification,
change, combination, consolidation, merger, sale or conveyance, execute and deliver to the Trustee a supplemental indenture providing that the Holder of each Security then outstanding shall have the right to convert such Security into the kind and
amount of shares of stock and other securities and property (including cash) receivable upon such reclassification, change, combination, consolidation, merger, sale or conveyance by a Holder of the number of shares of Common Stock deliverable upon
conversion of such Security immediately prior to such reclassification, change, combination, consolidation, merger, sale or conveyance. In the event holders of Common Stock have the opportunity to elect the form of consideration to be received in
such reclassification, change, combination, consolidation, merger, sale or conveyance, the Company will make adequate provision whereby the Holders of the Securities shall have the opportunity, on a timely basis, to determine the form of
consideration into which all of the Securities, treated as a single class, shall be convertible. The form of consideration into which all of the Securities, treated as a single class, shall be convertible, shall be determined by the Holders of a
majority of the Securities (based on principal amount outstanding thereunder) who have made an election as to such form of consideration and shall be subject to any limitations to which all of the holders of Common Stock are subject, such as pro
rata reductions applicable to any portion of the consideration payable. In the event that the Holders do not make such election on or prior to the date 10 days after receipt of notice that such election is required, then for the purposes of this
Section 4.11 the kind and amount of securities, cash or other property receivable upon such reclassification, change, combination, consolidation, merger, sale or conveyance by each Holder shall be deemed to be the kind and amount so receivable
by holders of a plurality of the Common Stock. Such supplemental indenture shall provide for adjustments of the Conversion Price which shall be as nearly equivalent as may be practicable to the adjustments of the Conversion Price provided for in
this Article 4. If, in the case of any such consolidation, merger, combination, sale or conveyance, the stock or other securities and property (including cash) receivable thereupon by a holder of Common Stock include shares of stock or other
securities and property of a person other than the successor, purchasing or transferee corporation, as the case may be, in such consolidation, merger, combination, sale or conveyance, then such supplemental indenture shall also be executed by such
other person and shall contain such additional provisions to protect the interests of the Holders of the Securities as the Board of Directors shall reasonably consider necessary by reason of the foregoing. Appropriate provisions will be made, as
determined in good faith by the Company’s Board of Directors, to preserve the settlement provisions of Section 4.14 following such reclassification, change, consolidation, merger, share exchange, combination, sale or conveyance to the
extent feasible. The Company may not become a party to any such transaction unless its terms are consistent with this Section 4.11. 
 In the event the Company shall execute a supplemental indenture pursuant to this Section 4.11, the Company shall promptly file with the Trustee (x) an Officers’ Certificate briefly stating the reasons therefor, 

  

 -33- 

 
the kind or amount of shares of stock or other securities or property (including cash) receivable by Holders of the Securities upon the conversion of their
Securities after any such reclassification, change, combination, consolidation, merger, sale or conveyance, any adjustment to be made with respect thereto and that all conditions precedent have been complied with and (y) an Opinion of Counsel
that all conditions precedent have been complied with, and shall promptly mail notice thereof to all Holders. 
 SECTION 4.12.
TRUSTEE’S DISCLAIMER.
 The Trustee shall have no duty to determine when an adjustment under this Article 4 should be made, how
it should be made or what such adjustment should be, but may accept as conclusive evidence of that fact or the correctness of any such adjustment, and shall be protected in relying upon, an Officers’ Certificate including the Officers’
Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.9. The Trustee makes no representation as to the validity or value of any securities or assets issued upon conversion of Securities,
and the Trustee shall not be responsible for the Company’s failure to comply with any provisions of this Article 4. 
 The Trustee
shall not be under any responsibility to determine the correctness of any provisions contained in any supplemental indenture executed pursuant to Section 4.11, but may accept as conclusive evidence of the correctness thereof, and shall be fully
protected in relying upon, the Officers’ Certificate with respect thereto which the Company is obligated to file with the Trustee pursuant to Section 4.11. 
 SECTION 4.13. VOLUNTARY REDUCTION.
 The Company from time to time may reduce the Conversion Price
by any amount for any period of time if the period is at least 20 days and if the reduction is irrevocable during the period if the Board of Directors determines that such reduction would be in the best interest of the Company or to avoid or
diminish income tax to holders of shares of the Common Stock in connection with a dividend or distribution of stock or similar event, and the Company provides 15 days prior notice of any reduction in the Conversion Price; provided,
however, that in no event may the Company reduce the Conversion Price to be less than the par value of a share of Common Stock. 
 SECTION 4.14. PAYMENT OF CASH IN LIEU OF COMMON STOCK.
 (a) In lieu of delivery of some or all of the shares of Common
Stock otherwise issuable upon notice of conversion of any Securities, at the Company’s option the Holders surrendering Securities for conversion shall receive for each $1,000 principal amount of Securities surrendered for conversion:
(A) cash in an amount equal to the lesser of (1) $1,000 and (2) the Conversion Value; and, in addition to amounts distributed pursuant to (A), (B) if the Conversion Value is greater than $1,000, a number of shares of Common Stock
equal to the sum of the Daily Share Amounts for each of the 20 consecutive Trading Days in the Conversion Reference Period, appropriately adjusted to reflect stock splits, stock dividends, combinations or similar events occurring during the
Conversion Reference Period, subject to the Company’s right to deliver cash in lieu of all or a portion of such shares as set forth in Section 4.14(b). The Company will deliver such cash and any shares of Common Stock, together with any
cash payable for fractional shares, to such holder in accordance with Section 4.2(a). 
 (b) The Company may elect to pay cash to the
Holders of Securities surrendered for conversion in lieu of all or a portion of the Common Stock otherwise issuable pursuant to Section 4.14(a). In such event, on any day prior to the first Trading Day of the applicable Conversion Reference
Period, the Company will 

  

 -34- 

 
specify a percentage of the Daily Share Amount that will be settled in cash (the “Cash Percentage”) and the amount of cash that the Company will
pay in respect of each Trading Day in the applicable Conversion Reference Period will equal the product of: (1) the Cash Percentage, (2) the Daily Share Amount for such Trading Day and (3) the Closing Price of the Common Stock for
such Trading Day (provided that after the consummation of a Change in Control in which the consideration is comprised entirely of cash, the amount used in this clause (3) will be the cash price per share received by holders of the Common Stock
in such Change in Control). The number of shares that the Company shall deliver in respect of each Trading Day in the applicable Conversion Reference Period will be a percentage of the Daily Share Amount equal to 100% minus the Cash Percentage. Upon
making a determination that a percentage of the Daily Share Amount will be settled in cash, the Company shall promptly provide notice of such information to the Holders in the manner provided in Section 12.2 prior to the first Trading Day of
the applicable Conversion Reference Period. If the Company does not specify a Cash Percentage by the start of the applicable Conversion Reference Period, the Company shall settle 100% of the Daily Share Amount for each Trading Day in the applicable
Conversion Reference Period with shares of Common Stock; provided, however, that the Company shall pay cash in lieu of fractional shares otherwise issuable upon conversion of Securities. 
 (c) For the purposes of Sections 4.14(a) and (b), in the event that any of Conversion Value, Daily Share Amounts or Volume Weighted Average Price cannot
be determined for all portions of the Conversion Reference Period, the Company’s Board of Directors shall in good faith determine the values necessary to calculate the Conversion Value, Daily Share Amounts and Volume Weighted Average Price, as
applicable.

the Trustee in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Company payment of interest (including
any Additional Interest and/or Extension Fee), if any, may be made by check mailed to the address of the Person entitled thereto as such address appears in the register of the Securities maintained at the Primary Registrar; provided
further that a Holder with an aggregate principal amount in excess of $2,000,000 will be paid by wire transfer in immediately available funds at the election of such Holder if such Holder has provided wire transfer instructions to the Company
at least 10 Business Days prior to the payment date. 
 SECTION 6.2. SEC REPORTS.
 The Company shall timely file all reports and other information and documents which it is required to file with the SEC pursuant to Section 13 or

Company shall file copies of all such reports, information and other documents with the Trustee. 
 Delivery of such reports, information and
documents to the Trustee is for informational 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). 
 SECTION 6.3. COMPLIANCE CERTIFICATES.
 The Company shall deliver to the Trustee, within

 Within the period prior to the expiration of the holding period applicable to sales thereof under Rule 144(k) under the Securities Act (or any
successor provision), the Company covenants and agrees that it shall, during any period in which it is not subject to Section 13 or 15(d) under the Exchange Act, upon the request of any Holder or beneficial holder of the Securities make

may reasonably request, all to the extent required from time to time to enable such Holder or beneficial holder to sell its Securities or Common Stock without registration under the Securities Act within the limitation of the exemption provided by
Rule 144A, as such Rule may be amended from time to time. Upon the request of any Holder or any beneficial holder of the Securities or such Common Stock, the Company will deliver to such Holder a written statement as to whether it has complied
with such requirements. 
 SECTION 6.7. STAY, EXTENSION AND USURY LAWS.
 The Company covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the 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, premium, if any, or interest (including any Additional Interest and/or
Extension Fee), if any, on the Securities as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture, and 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 will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of

Extension Fee is payable and (iii) the date on which such Additional Interest or Extension Fee is payable. Unless and until a Trust Officer of the Trustee receives such a certificate, the Trustee may assume without inquiry that no such
Additional Interest or Extension Fee is payable. If the Company has paid Additional Interest or an Extension Fee directly to the Persons entitled to such Additional Interest or Extension Fee, the Company shall deliver to the Trustee a certificate
setting forth the particulars of such payment.

 ARTICLE 8 
 DEFAULT AND REMEDIES 
 SECTION 8.1. EVENTS OF DEFAULT.
 An “Event of Default” shall occur if: 
 (1) the Company defaults in the payment of any interest (including any Additional Interest and/or Extension Fee), if any, on any Security when the same becomes due and payable and the default continues for a period of 30 days;

 (2) the Company defaults in the payment of any principal of (including, without limitation, any premium, if any, on) any Security when the
same becomes due and payable (whether at maturity, upon a Designated Event Purchase Date or otherwise);

there may be issued or by which there may be secured or evidenced any indebtedness for money borrowed by the Company or any Significant Subsidiary (all or substantially all of the outstanding voting securities of which are owned, directly or
indirectly, by the Company) (an “Instrument”) with a principal amount then outstanding in excess of U.S. $15,000,000, whether such indebtedness now exists or shall hereafter be created, is not paid at final maturity of the Instrument
(either at its stated maturity or upon acceleration thereof), and such indebtedness is not discharged, or such acceleration is not rescinded or annulled, within a period of 30 days after there shall have been given, by registered or certified
mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Securities then outstanding a written notice specifying such default and requiring the Company to cause such
indebtedness to be discharged or cause such default to be cured or waived or such acceleration to be rescinded or annulled and stating that such notice is a “Notice of Default” hereunder; 
  

 -39- 

 (8) the Company fails to file its annual or quarterly reports in accordance with Sections 6.2 or 6.6 or
to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act (a “Filing Failure”) and there has been given, by registered or certified mail, to the Company and the Trustee by the Holders of not less than 25% in
aggregate principal amount of the Securities then outstanding, a written notice specifying such default and requiring the Company to cause such default to be cured or waived and stating that such notice is a “Notice of Default” hereunder

(180) days after such notice is given if the Company has elected to pay the Extension Fee as provided in this Section 8.1 (and no Event of Default under this clause 8.1(8) shall be deemed to occur until the passage of such sixty
(60) day or such one hundred and eighty (180) day period, as applicable), provided that for purposes of this Section 8.1(8), no Filing Failure shall be deemed to have occurred if the Company files such reports within any extension
period pursuant to Rule 12b-25 of the Exchange Act or any successor rule thereto and that no Notice of Default shall be given until after the expiration of such extension period; 
 (9) the Company or any Significant Subsidiary, pursuant to or within the meaning of any Bankruptcy Law: 
  

	 	(A)	commences a voluntary case or proceeding; 

  

	 	(B)	consents to the entry of an order for relief against it in an involuntary case or proceeding;

	 	(C)	orders the liquidation of the Company or any Significant Subsidiary; 

 and
in each case the order or decree remains unstayed and in effect for 60 consecutive days. 
 The term “Bankruptcy Law” means
Title 11 of the United States Code (or any successor thereto) or any similar federal or state law for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, sequestrator or similar official
under any Bankruptcy Law. 
 A default under clause (3) above is not an Event of Default until the Trustee notifies the Company, or the
Holders of at least 25% in aggregate principal amount of the Securities then outstanding notify the Company and the Trustee, in writing of the default, and the Company does not cure the default within 60 days 

  

 -40- 

 
after receipt of such notice. The notice given pursuant to this Section 8.1 must specify the default, demand that it be remedied and state that the
notice is a “Notice of Default.” When any default under this Section 8.1 is cured, it ceases. 
 Upon the occurrence of a
Filing Failure, the Company may elect, within sixty (60) days of the date notice is given to the Company and the Trustee in accordance with Section 8.1(8) (unless such Filing Failure is theretofore cured or waived pursuant to
Section 8.4, as applicable), to pay to the Holders a fee accruing at the rate of 1.00% per annum of the aggregate principal amount of Securities that are then outstanding (the “Extension Fee”) on the terms and in the manner
described in this paragraph. If the Company elects to pay any Extension Fee, the Company, at any time on or before the close of business on the Business Day immediately prior to the sixtieth (60th) day after the date on which the applicable
Filing Failure first occurs, (i) shall notify, in the manner provided for in Section 12.2, the Holders and the Trustee of such election and (ii) shall deliver to the Trustee a certificate to that effect stating the date on which the
applicable Extension Fee pursuant to this paragraph will begin to accrue. The Extension Fee shall be paid on the same times and in the same manner as interest and Additional Interest, if any, shall be paid in accordance with this Indenture. The
Extension Fee shall accrue on the Securities from the date that is sixty (60) days after date notice is given by the Holders in accordance with Section 8.1(8) to, but excluding, the earlier of (i) the date on which the Company has
made the filings initially giving rise to the Filing Failure and (ii) the date that is one hundred eighty (180) days after the date notice is given by the Holders in accordance with Section 8.1(8). Notwithstanding the foregoing, if an
additional Filing Failure occurs during an Extension Period, the Securities will only be subject to acceleration for such additional Filing Failure at the earlier of (x) the end of the Extension Period and (y) in the event that the Company
has agreed to pay an Extension Fee in accordance with the terms of this Section 8.1 as to such additional Filing Failure, the end of the Extension Period as to such additional Filing Failure. For the avoidance of doubt, notwithstanding the
occurrence of multiple concurrent Filing Failures, the Extension Fee shall not exceed the rate provided for in this paragraph. 
 The Trustee
shall not be charged with knowledge of any Event of Default unless written notice thereof shall have been given to a Trust Officer at the Corporate Trust Office of the Trustee by the Company, a Paying Agent, any Holder or any agent of any Holder.

 SECTION 8.2. ACCELERATION.
 (a) If an Event of Default (other than an Event of Default specified in clause (9) or (10) of Section 8.1) occurs and is continuing, the Trustee may, by notice to the Company, or the Holders of at least 25% in aggregate
principal amount of the Securities then outstanding may, by notice to the Company and the Trustee, declare all unpaid principal to the date of acceleration on the Securities then outstanding (if not then due and payable) to be due and payable upon
any such declaration, and the same shall become and be immediately due and payable. If an Event of Default specified in clause (9) or (10) of Section 8.1 occurs, all unpaid principal of the Securities then outstanding shall ipso facto
become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder. The Holders of a majority in aggregate principal amount of the Securities then outstanding by notice to the Trustee may rescind
an acceleration and its consequences if (a) all existing Events of Default, other than the nonpayment of the principal of the Securities which has become due solely by such declaration of acceleration, have been cured or waived; (b) to the
extent the payment of such interest is lawful, interest at a rate borne by the Securities on overdue installments of interest (including any Additional Interest and/or Extension Fee), if any, and overdue principal, which has become due otherwise
than by such declaration of acceleration, has been paid; (c) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (d) all payments due to the Trustee and any predecessor Trustee under
Section 9.7 have been made. No such rescission shall affect any subsequent default or impair any right consequent thereto. 
  

 -41- 

 SECTION 8.3. OTHER REMEDIES.
 If an Event of Default occurs and is continuing, the Trustee may, but shall not be obligated to, pursue any available remedy by proceeding at law or in
equity to collect the payment of the principal of or interest (including any Additional Interest and/or Extension Fee), if any, on the Securities or to enforce the performance of any provision of the Securities or this Indenture. 
 The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or
omission by the Trustee or any Securityholder 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 to the extent permitted by law. 
 SECTION 8.4. WAIVER OF DEFAULTS AND EVENTS OF
DEFAULT.
 Subject to Sections 8.7 and 11.2, the Holders of a majority in aggregate principal amount of the Securities then
outstanding by notice to the Trustee may waive an existing default or Event of Default and its consequence, except a default or Event of Default in the payment of the principal of, premium, if any, or interest (including any Additional Interest
and/or Extension Fee), if any, on any Security, a failure by the Company to convert any Securities into Common Stock or any default or Event of Default in respect of any provision of this Indenture or the Securities which, under Section 11.2,
cannot be modified or amended without the consent of the Holder of each Security affected. When a default or Event of Default is waived, it is cured and ceases. 
 SECTION 8.5. CONTROL BY MAJORITY.
 The Holders of a majority in aggregate principal amount of the
Securities then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that
conflicts with law or this Indenture, that the Trustee determines may be unduly prejudicial to the rights of another Holder or the Trustee, or that may involve the Trustee in personal liability unless the Trustee is offered indemnity satisfactory to
it; provided, however, that the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 
 SECTION 8.6. LIMITATIONS ON SUITS.
 A Holder may not pursue any remedy with respect to this
Indenture or the Securities (except actions for payment of overdue principal, premium, if any, or interest (including any Additional Interest and/or Extension Fee), if any, for the conversion of the Securities pursuant to Article 4) unless:

 (1) the Holder gives to the Trustee written notice of a continuing Event of Default; 
 (2) the Holders of at least 25% in aggregate principal amount of the then outstanding Securities make a written request to the Trustee to pursue the
remedy; 
  

 -42- 

 (3) such Holder or Holders offer to the Trustee reasonable indemnity to the Trustee against any loss,
liability or expense; 
 (4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of
indemnity; and 
 (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the
Holders of a majority in aggregate principal amount of the Securities then outstanding. 
 A Securityholder may not use this Indenture to
prejudice the rights of another Securityholder or to obtain a preference or priority over such other Securityholder. 
 SECTION 8.7.
RIGHTS OF HOLDERS TO RECEIVE PAYMENT AND TO CONVERT.
 Notwithstanding any other provision of this Indenture, the right of any Holder of a
Security to receive payment of the principal of and interest (including any Additional Interest and/or Extension Fee), if any, on the Security, on or after the respective due dates expressed in the Security and this Indenture, to convert such
Security in accordance with Article 4 and to bring suit for the enforcement of any such payment on or after such respective dates or the right to convert, is absolute and unconditional and shall not be impaired or affected without the consent
of the Holder. 
 SECTION 8.8. COLLECTION SUIT BY TRUSTEE.
 If an Event of Default in the payment of principal or interest (including any Additional Interest and/or Extension Fee), if any, specified in
clause (1) or (2) of Section 8.1 occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an express trust against the Company or another obligor on the Securities for the whole amount of principal
and accrued interest (including any Additional Interest and/or Extension Fee), if any, remaining unpaid, together with, to the extent that payment of such interest is lawful interest on overdue principal and overdue installments of interest
(including any Additional Interest and/or Extension Fee), if any, in each case at a rate borne by the Securities and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel. 
 SECTION 8.9. 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 counsel) and the Holders allowed in any judicial proceedings relative to the Company (or any other
obligor on the Securities), its creditors or its property and shall be entitled and empowered to collect and receive any money or other property payable or deliverable on any such claims and to distribute the same, and any Custodian in any such
judicial proceeding is hereby authorized by each Holder to make such 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 to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 9.7, and to the extent that such payment of the reasonable compensation, expenses,
disbursements and advances in any such proceedings shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all 

  

 -43- 

 
distributions, dividends, money, securities and other property which the Holders may be entitled to receive in such proceedings, whether in liquidation or
under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to, or, on behalf of any Holder, to authorize, accept or adopt any plan of reorganization,
arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 SECTION 8.10. PRIORITIES.
 If the
Trustee collects any money pursuant to this Article 8, it shall pay out the money in the following order: 
 First, to the Trustee for
amounts due under Section 9.7; 
 Second, to Holders for amounts due and unpaid on the Securities for principal and interest (including
any Additional Interest and/or Extension Fee), if any, ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal and interest (including any Additional Interest and/or Extension
Fee), if any, respectively; and 
 Third, the balance, if any, to the Company. 
 The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 8.10. 
 SECTION 8.11. 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 and
good faith of the claims or defenses made by the party litigant. This Section 8.11 does not apply to a suit made by the Trustee, a suit by a Holder pursuant to Section 8.7, or a suit by Holders of more than 10% in aggregate principal
amount of the Securities then outstanding.

and is continuing and if it is known to the Trustee, the Trustee shall mail to each Securityholder notice of the default or Event of Default within 90 days after it occurs. However, the Trustee may withhold the notice if and so long as a

Trustee at the expense of the Company. 
 If the Trustee fails to comply with Section 9.10, any Holder may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

of any liabilities that the retiring Trustee may have incurred while acting as Trustee) hereunder, 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. A successor Trustee shall mail notice of its succession to each Holder.

any surviving rights of conversion, registration of transfer or exchange of Securities herein expressly provided for and except as further provided below), and the Trustee, on demand of and at the expense of the Company, shall execute proper

Date; 
 (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and 
  

 -49-

 The Trustee and each Paying Agent shall pay to the Company upon request any money held by them for the payment of principal or interest (including any
Additional Interest and/or Extension Fee), if any, that remains unclaimed for two years after a right to such money has matured; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment,
may at the expense of the Company cause to be mailed to each Holder entitled to such money notice that such money remains unclaimed and that after a date specified therein, which shall be at least 30 days from the date of such mailing, any
unclaimed balance of such money then remaining will be repaid to the Company. After payment to the Company, Holders entitled to money must look to the Company for payment as general creditors unless an applicable abandoned property law designates
another person. 
 SECTION 10.4. REINSTATEMENT.
 If the Trustee or any Paying Agent is unable to apply any money in accordance with Section 10.2 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, then the Company’s obligations under this Indenture and the Securities shall be revived and reinstated as though no deposit had occurred pursuant to Section 10.1 until such
time as the Trustee or such Paying Agent is permitted to apply all such money in accordance with Section 10.2; provided, however, that if the Company has made any payment of the principal of or interest (including any Additional
Interest and/or Extension Fee), if any, on any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive any such payment from the money held by the Trustee

 Commencing on May 20, 2009, the Company may at its
option redeem the Securities, in whole or in part, at any time upon notice as set forth in Article 13.3 at a redemption price (the “Redemption Price”) (expressed as a percentage of the principal amount) of 100% of the principal amount
of the Securities redeemed, together with accrued interest (including any Additional Interest and/or Extension Fee), if any, to, but excluding, the Redemption Date; provided, however, if such Redemption Date is an Interest Payment
Date, the interest due on such Interest Payment Date shall be payable to the Holder of the Securities called for redemption registered as such on the relevant Record Date and the Redemption Price shall not include such interest payment. 

In the event of a redemption of the Securities, the Company will not be required (a) to register the transfer or exchange of Securities for a
period of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities called for such redemption or (b) to register the transfer or exchange of any Security, or portion thereof, called for redemption.

 SECTION 13.2. APPLICABILITY OF ARTICLE.

 If less than all the Securities are to be redeemed, the Trustee shall select the particular Securities to be redeemed (in principal amounts of $1,000 or
integral multiples thereof), from the outstanding Securities by a method that complies with the requirements of any exchange on which the Securities are listed, or, if the Securities are not listed on an exchange, on a pro rata basis or by lot or in
accordance with any other method the Trustee considers fair and appropriate. 
 If any Security selected for partial redemption is converted
in part before termination of the conversion right with respect to the portion of the Security so selected, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption; provided, however, that
the Holder of such Security so converted and deemed redeemed shall not be entitled to any interest payment as a result of such deemed redemption in excess of such interest as such Security would have otherwise been entitled to receive upon
conversion of such Security. Securities that have been converted during a selection of Securities to be redeemed may be treated by the Trustee as outstanding for the purpose of such selection. The Trustee shall promptly notify the Company and each
Primary Registrar in writing of the securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 
 For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the
case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed.

in Section 12.2 to the Holders of Securities to be redeemed not less than 20 nor more than 60 days prior to the Redemption Date, and such notice shall be irrevocable.

 (b) the Redemption Price and accrued interest (including any Additional Interest and/or Extension Fee), if any, to,
but excluding, the Redemption Date; 
 (c) if less than all Securities then outstanding are to be redeemed, the aggregate principal amount of
Securities to be redeemed and the aggregate principal amount of Securities which will be outstanding after such partial redemption; 
 (d)
that on the Redemption Date the Redemption Price and accrued interest (including any Additional Interest and/or Extension Fee), if any, to, but excluding, the Redemption Date, will become due and payable upon each such Security to be redeemed, and
that interest thereon shall cease to accrue on and after said date; 
 (e) the Conversion Rate, the date on which the right to convert the
Securities to be redeemed will terminate and the places where such Securities may be surrendered for conversion; and 
  

 -58- 

 (f) the place or places where such Securities are to be surrendered for payment of the Redemption Price
and accrued interest (including any Additional Interest and/or Extension Fee), if any, to, but excluding, the Redemption Date.

by the Trustee in the name of and at the expense of the Company. Notice of redemption of Securities to be redeemed at the election of the Company received by the Trustee shall be given by the Trustee to each Paying Agent in the name of and at the
expense of the Company.

Additional Interest and/or Extension Fee), if any, to, but excluding, the Redemption Date on all the Securities which are to be redeemed on that date, other than any Securities called for redemption on that date which have been converted prior to
the date of such deposit. 
 If any Security called for redemption is converted, any money deposited with the Trustee or so segregated and
held in trust for the redemption of such Security shall (subject to any right of the Holder of such Security or any predecessor Security to receive interest as provided in paragraph 6 of the form of Security attached hereto as Exhibit A) be
returned to the Company on company request or, if then held by the Company, shall be discharged from such trust. 
 SECTION 13.7.
SECURITIES PAYABLE ON REDEMPTION DATE.
 Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on
the Redemption Date, become due and payable at the Redemption Price therein specified and from and after such date (unless the Company shall default in the payment of the Redemption Price, including accrued interest) such Securities shall cease to
bear interest and such Securities shall cease at the close of business on the Business Day immediately preceding the date fixed for redemption to be convertible into common stock and, except as provided in Sections 10.2 and 10.3, to be entitled to

the Holders of such Securities, or one or more predecessor Securities, registered as such on the relevant Record Date according to their terms and the provisions of Article 2 of this Indenture. 
 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal amount of, premium, if any, and, to the
extent permitted by applicable law, accrued interest on such Security shall, until paid, bear interest from the Redemption Date at the rate borne by the Securities and such Security shall remain convertible until the Redemption Price of such
Security (or portion thereof, as the case may be) shall have been paid or duly provided for. 
  

 -59- 

 Any Security that is to be redeemed only in part shall be surrendered at the Corporate Trust Office or an
office or agency of the Company designated for that purpose (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder
thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee shall authenticate and make available for delivery to the Holder of such Security without service charge, a new Security or Securities, of any
authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. 
 SECTION 13.8. CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION.
 In connection with any redemption of Securities, the Company may arrange for the purchase and conversion of any Securities by an agreement with one or more investment bankers or other purchasers (the
“Purchasers”) to purchase such Securities by paying to the Trustee in trust for the Holders, on or before the Redemption Date, an amount not less than the applicable Redemption Price, together with interest accrued to, but excluding, the
Redemption Date, of such Securities. Notwithstanding anything to the contrary contained in this Article 13 the obligation of the Company to pay the Redemption Price, together with interest accrued to, but excluding, the Redemption Date, shall be
deemed to be satisfied and discharged to the extent such amount is so paid by such Purchasers. If such an agreement is entered into (a copy of which shall be filed with the Trustee prior to the close of business on the Business Day immediately prior
to the Redemption Date), any Securities called for redemption that are not duly surrendered for conversion by the Holders thereof may, at the option of the Company, be deemed, to the fullest extent permitted by law, and consistent with any agreement
or agreements with such Purchasers, to be acquired by such Purchasers from such Holders and (notwithstanding anything to the contrary contained in Article 4) surrendered by such Purchasers for conversion, all as of immediately prior to the close of
business on the Redemption Date (and the right to convert any such Securities shall be extended through such time), subject to payment of the above amount as aforesaid. At the direction of the Company, the Trustee shall hold and dispose of any such
amount paid to it by the Purchasers to the Holders in the same manner as it would monies deposited with it by the Company for the redemption of Securities. Without the Trustee’s prior written consent, no arrangement between the Company and such
Purchasers for the purchase and conversion of any Securities shall increase or otherwise affect any of the powers, duties, responsibilities or obligations of the Trustee as set forth in this Indenture, and the Company agrees to indemnify the Trustee
from, and hold it harmless against, any loss, liability or expense arising out of or in connection with any such arrangement for the purchase and conversion of any Securities between the Company and such Purchasers, including the costs and expenses,
including reasonable legal fees, incurred by the Trustee in the defense of any claim or liability arising out of or in connection with the exercise or performance of any of its powers, duties, responsibilities or obligations under this Indenture.

 At the option of the Holder and subject to the terms and conditions of the Indenture, the Company shall become obligated to purchase all or any part specified by the Holder (so long as the principal amount of such
part is $1,000 or an integral multiple of $1,000 in excess thereof) of the Securities held by such Holder on the date that is thirty (30) Business Days after the occurrence of a Designated Event, at a purchase price equal to 100% of the
principal amount of the Securities to be repurchased thereof together with accrued interest (including any Additional Interest and/or Extension Fee), if any, up to, but excluding, the Designated Event Purchase Date. The Holder shall have the right
to withdraw any Designated Event Purchase Notice (in whole or in a portion thereof that is $1,000 or an integral multiple of $1,000 in excess thereof) at any time prior to the close of business on the Business Day next preceding the Designated Event
Purchase Date by delivering a written notice of withdrawal to the Paying Agent in accordance with the terms of the Indenture. 
 6. CONVERSION 
 Subject to the obligation and the right of the Company to pay some or all of the conversion consideration in cash in accordance with Section 4.14 of
the Indenture, and upon compliance with the provisions of the Indenture, including, without limitation, the provisions of Section 4.1(a) of the Indenture, and upon the occurrence of the events specified in the Indenture, the registered holder
of this Security has the right at any time on or before the close of business on the last Trading Day prior to the Final Maturity Date (or in case this Security or any portion hereof is subject to a duly completed election for repurchase, on or
before the close of business on the Designated Event Purchase Date (unless the Company defaults in payment due upon repurchase or such holder elects to withdraw the submission of such election to repurchase)) to convert the principal amount hereof,
or any portion of such principal amount which is $1,000 or an integral multiple thereof. 
 The initial Conversion Price is $15.00 per share,
subject to adjustment under certain circumstances as provided in the Indenture. The number of shares of Common Stock issuable upon conversion of a Security is determined by dividing the principal amount of the Security or portion thereof converted
by the Conversion Price in effect on the Conversion Date. No fractional shares will be issued upon conversion; in lieu thereof, an amount will be paid in cash based upon the Closing Price (as defined in the Indenture) of the Common Stock on the
Trading Day immediately prior to the Conversion Date. 
  

 A-7 

 In lieu of delivery of some or all of the shares of Common Stock otherwise issuable upon notice of
conversion of any Securities, at the Company’s option the Holders surrendering Securities for conversion will receive, for each $1,000 principal amount of Securities surrendered for conversion: 
  

	 	–	cash in an amount equal to the lesser of (1) $1,000 and (2) the Conversion Value; and 

  

	 	–	if the Conversion Value is greater than $1,000, a number of shares of Common Stock equal to the sum of the Daily Share Amounts, for each of the twenty consecutive Trading Days in
the Conversion Reference Period, appropriately adjusted to reflect stock splits, stock dividends, combinations or similar events occurring during the Conversion Reference Period, subject to the Company’s right to deliver cash in lieu of all or
a portion of such shares as set forth in Section 4.14 of the Indenture. 

 The Conversion Rate on any Securities
surrendered in connection with a Designated Event may be increased by an amount, if any, determined in accordance with Section 4.1(h) of the Indenture. 
 To convert a Security, a Holder must (a) complete and manually sign the conversion notice set forth below and deliver such notice to a Conversion Agent, (b) surrender the Security to a Conversion Agent,
(c) furnish appropriate endorsements and transfer documents if required by a Registrar or a Conversion Agent, and (d) pay any transfer or similar tax, if required. Securities so surrendered for conversion (in whole or in part) during the
period from the close of business on any Record Date to the opening of business on the next succeeding Interest Payment Date, if any, (excluding Securities or portions thereof called for redemption by the Company or subject to purchase upon a
Designated Event on a Designated Event Purchase Date, during the period beginning at the close of business on a Record Date and ending at the opening of business on the first Business Day after the next succeeding Interest Payment Date, if any, or
if such Interest Payment Date, if any, is not a Business Day, the second such Business Day) shall also be accompanied by payment in funds acceptable to the Company of an amount equal to the interest (including any Additional Interest, but not the
Extension Fee), if any, payable on such Interest Payment Date, if any, on the principal amount of such Security then being converted, and such interest, if any, shall be payable to such registered Holder notwithstanding the conversion of such
Security, subject to the provisions of this Indenture relating to the payment of defaulted interest, if any, by the Company. If the Company defaults in the payment of interest payable on such Interest Payment Date, if any, the Company shall promptly
repay such funds to such Holder. A Holder may convert a portion of a Security equal to $1,000 or any integral multiple thereof. 
 A Security
in respect of which a Holder had delivered a Designated Event Purchase Notice exercising the option of such Holder to require the Company to purchase such Security may be converted only if the Designated Event Purchase Notice is withdrawn in
accordance with the terms of the Indenture. 
 7. RANKING

The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes or other governmental charges that may be imposed in relation thereto by law or permitted by the Indenture.

 9. PERSONS DEEMED OWNERS 
 The Holder of a
Security may be treated as the owner of it for all purposes. 
 10. UNCLAIMED MONEY 
 If money for the payment of principal or interest (including any Additional Interest and/or Extension Fee), if any, remains unclaimed for two years, the
Trustee or Paying Agent will pay the money back to the Company at its written request, subject to applicable unclaimed property law. After that, Holders entitled to money must look to the Company for payment as general creditors unless an applicable
abandoned property law designates another person. 
 11. AMENDMENT, SUPPLEMENT AND WAIVER 
 Subject to certain exceptions, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of at least a majority in
aggregate principal amount of the Securities then outstanding, and an existing default or Event of Default and its consequence or compliance with any provision of the Indenture or the Securities may be waived in a particular instance with the
consent of the Holders of a majority in aggregate principal amount of the Securities then outstanding. Without the consent of or notice to any Holder, the Company and the Trustee may amend or supplement the Indenture or the Securities to, among

payable immediately, all as and to the extent provided in the Indenture. If an Event of Default occurs as a result of certain events of bankruptcy, insolvency or reorganization of the Company, unpaid principal of the Securities then outstanding
shall become due and payable immediately without any declaration or other act on the part of the Trustee or any Holder, all as and to the extent provided in the Indenture. Holders may not enforce the Indenture or the Securities except as provided in
the Indenture. The Trustee may require indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the Securities then outstanding may direct
the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal or interest (including any Additional Interest and/or Extension Fee), if any) if it
determines that withholding notice is in their interests. The Company is required to file periodic reports with the Trustee as to the presence or absence of default. 
 14. REDEMPTION 
 The Securities are subject to redemption at the option of the Company at any time on or
after May 20, 2009, in whole or in part, upon not less than 20 nor more than 60 days’ notice to the Holders prior to the Redemption Date at a redemption price (the “Redemption Price”) (expressed as a percentage of the principal
amount) of 100% of the principal amount of the Securities redeemed, together with accrued interest to, but excluding, the Redemption Date; provided, however, if such Redemption Date is an Interest Payment Date, the interest due on such
Interest Payment Date shall be payable to the Holder of the Securities called for redemption registered as such on the relevant Record Date and the Redemption Price shall not include such interest payment. 
 In the event of a redemption of the Securities, the Company will not be required (a) to register the transfer or exchange of Securities for a period
of 15 days immediately preceding the date notice is given identifying the serial numbers of the Securities called for such redemption or (b) to register the transfer or exchange of any Security, or portion thereof, called for redemption

(check applicable box) 
  ̈  book-entry or     ̈  definitive form by

 The Transferor has requested a Registrar or the Trustee to exchange or register the transfer of such Securities. 
 In connection with such request and in respect of each such Security, the Transferor does hereby certify that the Transferor is familiar with transfer restrictions relating to the Securities as provided in Section 2.12 of the Indenture
dated as of March 5, 2007 between Magma Design Automation, Inc. and U.S. Bank National Association, as trustee (the “Indenture”), and the transfer of such Security is being made pursuant to an effective registration statement under the
Securities Act of 1933, as amended (the “Securities Act”) (check applicable box) or the transfer or exchange, as the case may be, of such Security does not require registration under the Securities Act because (check applicable box):

  

	 	 ̈	Such Security is being transferred pursuant to an effective registration statement under the Securities Act. 

  

	 	 ̈	Such Security is being acquired for the Transferor’s own account, without transfer. 

  

	 	 ̈	Such Security is being transferred to the Company or a Subsidiary (as defined in the Indenture) of the Company. 

  

	 	 ̈	Such Security is being transferred to a person the Transferor reasonably believes is a “qualified institutional buyer” (as defined in Rule 144A or any successor
provision thereto (“Rule 144A”) under the Securities Act) that is purchasing for its own account or for the account of a “qualified institutional buyer”, in each case to whom notice has been given that the transfer is being
made in reliance on such Rule 144A, and in each case in reliance on Rule 144A. 

  

	 	 ̈	Such Security is being transferred pursuant to and in compliance with an exemption from the registration requirements under the Securities Act in accordance with Rule 144 (or
any successor thereto) (“Rule 144”) under the Securities Act.

above) and as a result of which such Security will, upon such transfer, cease to be a “restricted security” within the meaning of Rule 144 under the Securities Act. 

 The Transferor acknowledges and agrees that, if the transferee will hold any such Securities in the form of beneficial interests in a global Security
which is a “restricted security” within the meaning of Rule 144 under the Securities Act, then such transfer can only be made pursuant to (i) Rule 144A under the Securities Act and such transferee must be a “qualified
institutional buyer” (as defined in Rule 144A) or (ii) Regulation S under the Securities Act.
