Registration Rights Agreement

 REGISTRATION RIGHTS AGREEMENT 
 This Registration Rights Agreement (this “Agreement”) is made and entered into as of December 5, 2007, by Avantair, Inc., a
Delaware corporation (the “Company”), in favor of each of the investors listed on Exhibit A (each, an “Investor”). 
 A. Pursuant to that certain Preferred Stock Purchase Agreement (the “Purchase Agreement”) dated as of December 5, 2007, by and
between the Company and Investor, the Investor has purchased shares (the “Purchase”) of the Company’s Series A Convertible Preferred Stock (the “Series A Preferred)”.

 B. Pursuant to the Purchase Agreement, the Company is required to provide the Investor certain registration rights with respect to the
shares of the Company’s Common Stock issuable upon conversion of the Series A Preferred. 
  

	 	1.	REGISTRATION RIGHTS. 

 1.1
Definitions. For purposes of this Section 1: 
 (a) Common Stock. The term “Common Stock”
means the Company’s common stock, $0.0001 par value per share. 
 (b) Registration. The terms
“register,” “registration” and “registered” refer to a registration effected by preparing and filing a registration statement in compliance with the Securities Act, and the
declaration or ordering of effectiveness of such registration statement. 
 (c) Registrable Securities. The term
“Registrable Securities” means (i) the Common Stock issuable upon conversion of the Series A Preferred and (ii) any shares of Common Stock of the Company issued as a dividend or other distribution with respect to,
or in exchange for or in replacement of, any shares of Common Stock described in clause (i). 
 (d) Registrable Securities Then
Outstanding. The number of shares of “Registrable Securities then outstanding” shall mean the number of shares of Common Stock which are Registrable Securities that are then (1) issued and outstanding or
(2) issuable pursuant to the conversion of the Series A Preferred or other convertible securities. 
 (e) Holder. The term
“Holder” means any person owning of record Registrable Securities or any assignee of record of such Registrable Securities to whom rights set forth herein have been duly assigned in accordance with this Agreement;
provided, however, that for purposes of this Agreement, a record holder of the Series A Preferred convertible into such Registrable Securities shall be deemed to be the Holder of such Registrable Securities; provided,
further, that Holders of Registrable Securities will not be required to convert their Series A Preferred into shares of Common Stock in order to exercise the registration rights granted hereunder. 
 (f) SEC. The term “SEC” or “Commission” means the U.S. Securities and Exchange Commission.

 1.2 Demand Registrations. 
 (a) Request by Holders. If the Company shall receive at any time after the three month anniversary of the date hereof, a written request from the
Holders of at least fifty percent (50%) of the then outstanding Registrable Securities (the “Initiating Holders”) that the Company file a registration statement under the Securities Act of 1933, as amended, (the
“Securities Act”) and, if by means of an underwriting, covering the registration of Registrable Securities pursuant to this Section 1.2, with an anticipated aggregate offering price of at least $7,500,000 (net of
underwriting discounts and commissions), then the Company shall, within twenty (20) days after the receipt of such written request, give written notice of such request (the “Request Notice”) to all Holders, and use all
reasonable efforts to effect, as soon as practicable, the registration under the Securities Act of all Registrable Securities which Holders request to be registered and included in such registration by written notice given by such Holders to the
Company within twenty (20) days after receipt of the Request Notice, subject only to the limitations of this Section 1. The Company may, if permitted by law, effect any registration pursuant to this Section 1.2 by the filing of a
registration statement on Form S-3. Any registration statement filed pursuant to this Section 1.2(a) may, subject to Section 1.2(c), include shares of Common Stock with respect to which the Company has registration obligations pursuant to
written contractual arrangements (“Other Registrable Securities”) including, if applicable, by post-effective amendment to any “shelf” registration filed with respect to any Registrable Securities. 
 (b) Mandatory Shelf Registration. The Company agrees to file with the SEC, in no event later the six month anniversary of the date hereof
(provided, that if the Company is eligible to file a registration statement on Form S-3, then such filing shall be made no later than the three month anniversary of the date hereof), a shelf registration statement on Form S-3 or such other form
under the Securities Act then available to the Company providing for the resale pursuant to Rule 415 from time to time by the Holders of any and all Registrable Securities (including the prospectus, amendments and supplements to such registration
statement or prospectus, including pre- and post-effective amendments, all exhibits thereto and all material incorporated by reference or deemed to be incorporated by reference, if any, in such registration statement, the “Mandatory Shelf
Registration Statement”); provided, however, that the Company will not file a registration statement on its behalf prior to filing the Mandatory Shelf Registration Statement. The Company shall use its commercially reasonable efforts to
cause such Mandatory Shelf Registration Statement to be declared effective by the SEC as soon as reasonably practicable following such filing; provided, however, that if the Mandatory Shelf Registration Statement is not declared effective by the SEC
on or prior to the nine month anniversary of the date hereof then the Company shall pay to each Investor an amount in cash equal to one and one-half percent (1.5%) of (i) the number of Series A Preferred held by such Investor as of such
date, multiplied by (ii) the purchase price paid by such Investor for such Series A Preferred then held; and on every monthly anniversary thereof until the Mandatory Shelf Registration Statement is declared effective by the SEC; provided
further, however, that if the SEC, by written or oral comment or otherwise, limits the Company’s ability to request effectiveness, or prohibits the effectiveness of, the Mandatory Shelf Registration Statement with respect to any or all the
Registrable Securities pursuant to Rule 415, it shall not be a breach or default by the Company under this Agreement and shall not be deemed a failure by the Company to use reasonable best efforts and no such penalty shall be due and payable. Any
Mandatory 

  

 2 

 
Shelf Registration Statement shall provide for the resale from time to time, and pursuant to any method or combination of methods legally available
(including, without limitation, an underwritten offering, a direct sale to purchasers, a sale through brokers or agents, or a sale over the Internet) by the Holders of any and all Registrable Securities. 
 (c) Underwriting. If the Holders initiating the registration request under this Section 1.2 (the “Initiating
Holders”) intend to distribute the Registrable Securities covered by their request by means of an underwriting, then they shall so advise the Company as a part of their request made pursuant to this Section 1.2 and the Company
shall include such information in the written notice referred to in subsection Section 1.2(a). In such event, the right of any Holder to include his, her, or its Registrable Securities in such registration shall be conditioned upon such
Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder) to the extent
provided herein. All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such underwriting by the Company.
Notwithstanding any other provision of this Section 1.2, if the underwriter(s) advise(s) the Company in writing that marketing factors require a limitation of the number of securities to be underwritten then the Company shall so advise all
Holders of Registrable Securities that would otherwise be registered and underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be reduced as required by the underwriter(s) and allocated
among the Holders of Registrable Securities on a pro rata basis according to the number of Registrable Securities then outstanding held by each Holder requesting registration (including the Initiating Holders); provided, however, that
the number of shares of Registrable Securities to be included in such underwriting and registration shall not be reduced unless all other securities of the Company are first entirely excluded from the underwriting and registration. Any Registrable
Securities excluded and withdrawn from such underwriting shall be withdrawn from the registration. 
 (d) Maximum Number of Demand
Registrations. The Company is obligated to effect only two such registrations pursuant to Section 1.2(a). 
 (e) Expenses.
All expenses incurred in connection with a registration pursuant to this Section 1.2, including without limitation all registration and qualification fees, printers’ and accounting fees, fees and disbursements of counsel for the Company
and reasonable fees and disbursements of a single counsel for all Holders (but excluding underwriters’ discounts and commissions), shall be borne by the Company. Each Holder participating in a registration pursuant to this Section 1.2
shall bear such Holder’s proportionate share (based on the number of shares sold by such Holder over the total number of shares included in such registration at the time it is declared effective) of all discounts, commissions or other amounts
payable to underwriters or brokers in connection with such offering. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to this Section 1.2 if the registration
request is subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be registered, unless the Holders of a majority of the Registrable Securities then outstanding agree to forfeit their right to a demand
registration pursuant to this Section 1.2 (in which case such right shall be forfeited by all Holders of Registrable Securities); provided, further, however, that if at the time of such withdrawal, the 

  

 3 

 
Holders have learned of a material adverse change in the condition, business, or prospects of the Company not known to the Holders at the time of their
request for such registration and have withdrawn their request for registration with reasonable promptness after learning of such material adverse change, then the Holders shall not be required to pay any of such expenses and shall retain their
demand registration rights pursuant to this Section 1.2. 
 1.3 Piggyback Registrations. The Company shall notify all
Holders of Registrable Securities in writing at least thirty (30) days prior to filing any registration statement under the Securities Act for purposes of effecting a public offering of securities of the Company (including, but not limited to,
registration statements relating to secondary offerings of securities of the Company, but excluding registration statements relating to any registration under Section 1.2, any employee benefit plan or a corporate reorganization or other
transaction covered by Rule 145 promulgated under the Securities Act, or a registration on any registration form which does not permit secondary sales or does not include substantially the same information as would be required to be included in
a registration statement covering the sale of Registrable Securities) and will afford each such Holder an opportunity to include in such registration statement all or any part of the Registrable Securities then held by such Holder. Each Holder
desiring to include in any such registration statement all or any part of the Registrable Securities held by such Holder shall, within twenty (20) days after receipt of the above-described notice from the Company, so notify the Company in
writing, and in such notice shall inform the Company of the number of Registrable Securities such Holder wishes to include in such registration statement. If a Holder decides not to include all of its Registrable Securities in any registration
statement thereafter filed by the Company, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statement or registration statements as may be filed by the Company with
respect to offerings of its securities, all upon the terms and conditions set forth herein. 
 (a) Underwriting. If a registration
statement under which the Company gives notice under this Section 1.3 is for an underwritten offering, then the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder’s Registrable
Securities to be included in a registration pursuant to this Section 1.3 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the
extent provided herein. All Holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the managing underwriter or underwriter(s) selected for such
underwriting. Notwithstanding any other provision of this Agreement, if the managing underwriter determine(s) in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the managing underwriter(s) may
exclude shares (including Registrable Securities) from the registration and the underwriting, and the number of shares that may be included in the registration and the underwriting shall be allocated, first, to the Company (assuming the
Company is the party which has requested the filing of such Registration Statement) or, if applicable, to the holders of Other Registrable Securities which, pursuant to written contractual arrangements, has demanded such registration, and
second to Holders requesting inclusion of their Registrable Securities in such registration statement and any holders of Other Registrable Securities requesting inclusion of their Other Registrable Securities in such registration statement on
a pro rata basis based on the number of Registrable Securities and Other Registrable Securities, as applicable, each such person has requested to be 

  

 4 

 
included in the registration. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice,
given in accordance with Section 3.1 hereof, to the Company and the underwriter, delivered at least ten (10) business days prior to the effective date of the registration statement. Any Registrable Securities excluded or withdrawn from
such underwriting shall be excluded and withdrawn from the registration. For any Holder that is a partnership or corporation, the partners, retired partners and shareholders of such Holder, or the estates and family members of any such partners and
retired partners and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “Holder,” and any pro rata reduction with respect to such “Holder” shall be based upon the aggregate amount of shares
carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this sentence. 
 (b)
Expenses. All expenses incurred in connection with a registration pursuant to this Section 1.3, including without limitation all registration and qualification fees, printers’ and accounting fees, fees and disbursements of counsel
for the Company (but excluding underwriters’ discounts and commissions) shall be borne by the Company. Each Holder participating in a registration pursuant to this Section 1.3 shall bear such Holder’s proportionate share (based on the
number of shares sold by such Holder over the total number of shares included in such registration at the time it goes effective) of all discounts, commissions or other amounts payable to underwriters or brokers in connection with such offering.

 1.4 Obligations of the Company. Whenever required to effect the registration of any Registrable Securities under this
Agreement, the Company shall, subject to the provisions of Section 1.4(f) below, as expeditiously as reasonably possible: 
 (a) Use its
best efforts to prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its commercially reasonable efforts to cause such registration statement to become effective, and, upon the request of the
Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for up to ninety (90) days. 
 (b) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions
of the Securities Act with respect to the disposition of all securities covered by such registration statement and comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities of the Company covered
by such registration statement until such time as all of such Registrable Securities registered thereunder shall have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in such
registration statement. In the case of amendments and supplements to a registration statement which are required to be filed pursuant to this Agreement by reason of the Company filing a report on Form 10-K, Form 10-Q or Form 8-K or any analogous
report under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company shall have incorporated such report by reference into such registration statement, if applicable, or shall file such amendments or
supplements with the SEC on the same day on which the Exchange Act report is filed which created the requirement for the Company to amend or supplement such registration statement. 
  

 5 

 (c) Furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in
conformity with the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of the Registrable Securities owned by them that are included in such registration. 
 (d) Use reasonable efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of
such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any
such states or jurisdictions. The Company shall promptly notify each Holder of the receipt by the Company of any notification with respect to the suspension of the registration or qualification of any of the Registrable Securities for sale under the
securities or “blue sky” laws of any jurisdiction in the United States or its receipt of actual notice of the initiation or threatening of any proceeding for such purpose. 
 (e) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter(s) of such offering and enter into such other customary agreements and take all such actions as such underwriter reasonably requests in order to expedite or facilitate the disposition of such shares. Each Holder
participating in such underwriting hereby agrees to also enter into and perform its obligations under such an agreement. 
 (f) Notify each
Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the occurrence of any event as a result of which the prospectus included
in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the
circumstances then existing and promptly prepare a supplement or amendment to such registration statement to correct such untrue statement or omission, and deliver ten (10) copies of such supplement or amendment to each Holder (or such other
number of copies as such Holder may reasonably request). 
 (g) The Company shall use its commercially reasonable efforts to
(i) prevent the issuance of any stop order or other suspension of effectiveness of any registration statement prepared hereunder, or the suspension of the qualification of any of the Registrable Securities for sale in any jurisdiction and,
(ii) if such an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest possible moment and to notify each Holder who holds Registrable Securities being sold of the issuance of such order and the
resolution thereof or its receipt of actual notice of the initiation or threat of any proceeding for such purpose. 
 (h) The Company shall
use its commercially reasonable efforts either to cause all the Registrable Securities covered by a registration statement prepared hereunder to be listed on each securities exchange on which securities of the same class or series issued by the
Company are then listed, if any, if the listing of such Registrable Securities is then permitted under the rules of such exchange. The Company shall pay all fees and expenses in connection with satisfying its obligation under this
Section 1.4(h). 
  

 6 

 (i) The Company shall cooperate with the Holders who hold Registrable Securities being offered and, to
the extent applicable, facilitate the timely preparation and delivery of certificates (not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to a registration statement filed hereunder and enable such
certificates to be in such denominations or amounts, as the case may be, as such Holders may reasonably request and registered in such names as such Holders may request. 
 (j) If requested by a Holder, the Company shall use its commercially reasonable efforts to (i) as soon as practicable incorporate in a prospectus supplement or post-effective amendment such information as a
Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being offered or sold, the purchase
price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; (ii) as soon as practicable make all required filings of such prospectus supplement or post-effective amendment after being
notified of the matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) as soon as practicable, supplement or make amendments to any registration statement if reasonably requested by a Holder holding any
Registrable Securities. 
 (k) Use commercially reasonable efforts to furnish, on or about the date that such Registrable Securities are
delivered to the underwriters for sale, if such securities are being sold through underwriters, copies of (i) the opinion, if any, of the lead legal counsel representing the Company for the purposes of such registration issued pursuant to the
underwriting agreement relating to the offering and addressed to the underwriters and (ii) the letter (including any “bring-downs” related thereto) from the independent certified public accountants of the Company issued pursuant to
the underwriting agreement relating to the offering and addressed to the underwriters. 
 (l) Notwithstanding any other provision of this Agreement, from and after the time a registration statement filed under this Section 1 covering Registrable Securities is declared effective, the Company shall have the right to suspend
the registration statement and the related prospectus in order to prevent premature disclosure of any material non-public information related to corporate developments by delivering notice of such suspension to the Holders, provided, however,
that the Company may exercise the right to such suspension only once in any 12-month period and for a period not to exceed 90 days. From and after the date of a notice of suspension under this Section 1.4(l), each Holder agrees not to use the
registration statement or the related prospectus for resale of any Registrable Security until the earlier of (1) notice from the Company that such suspension has been lifted or (2) the 90th
 day following the giving of the notice of suspension. 
 (m) Cause the principal
executive officer of the Company, the principal financial officer of the Company, the principal accounting officer of the Company and all other officers and members of the management of the Company to cooperate fully in any offering of Registrable
Securities hereunder, which cooperation shall include participation in meetings with underwriters, attorneys, accountants and potential investors. 
  

 7 

 (n) Make available for inspection by the Holders included in such registration statement, any
underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other professional retained by any Holder included in such registration statement or any underwriter, all financial and other
records, pertinent corporate documents and properties of the Company, as shall be necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors and employees to supply all information
reasonably requested by any of them in connection with such registration statement. 
 1.5 Furnish Information. It shall be a
condition precedent to the obligations of the Company to take any action pursuant to Section 1.2 or 1.3 that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them, and
the intended method of disposition of such securities as shall be required to timely effect the registration of their Registrable Securities. 
 1.6 Delay of Registration. No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 1. 
 1.7 Indemnification. In the event any Registrable Securities are
included in a registration statement under Section 1.2 or 1.3: 
 (a) By the Company. To the extent permitted by law, the Company
will indemnify and hold harmless each Holder, the partners, officers, directors, members, employees and agents of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or
underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state
law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively, the “Violations” and,
individually, a “Violation”): 
 (1) any untrue statement or alleged untrue statement of a material fact contained in
such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto; or 
 (2) 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; or 
 (3) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any federal or state securities law or any rule or
regulation promulgated under the Securities Act, the Exchange Act or any federal or state securities law in connection with the offering covered by such registration statement. 
 The Company will promptly reimburse each such Holder, partner, officer or director, underwriter or controlling person for any legal or other expenses reasonably incurred by them, after a request for reimbursement has
been received by the Company, in connection with investigating or 

  

 8 

 
defending any such loss, claim, damage, liability or action; provided however, that the indemnity agreement contained in this
Section 1.7(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall
the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished
expressly for use in connection with such registration by such Holder, partner, officer, director, underwriter or controlling person of such Holder. 
 (b) By Selling Holders. To the extent permitted by law, each selling Holder will be required severally and not jointly to indemnify and hold harmless the Company, each of its directors, employees, agents, each
of its officers who have signed the registration statement, each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter and any other Holder selling securities under such registration statement or any of
such other Holder’s partners, directors or officers or any person who controls such Holder within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages or liabilities (joint or several) to which the Company
or any such director, officer, controlling person, underwriter or other such Holder, partner or director, officer or controlling person of such other Holder may become subject under the Securities Act, the Exchange Act or other federal or state law,
insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity
with written information furnished by such Holder expressly for use in connection with such registration. Each such Holder will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling
person, underwriter or other Holder, partner, officer, director or controlling person of such other Holder in connection with investigating or defending any such loss, claim, damage, liability or action; promptly after a request for reimbursement
has been received by the indemnifying Holder, provided, however, that the indemnity agreement contained in this Section 1.7(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if
such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; and provided further, that the total amounts payable in indemnity by a Holder under this Section 1.7(b) in respect of
any Violation shall not exceed the net proceeds received by such Holder in the registered offering out of which such Violation arises. 
 (c) Notice. Promptly after receipt by an indemnified party under this Section 1.7 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to
be made against any indemnifying party under this Section 1.7, deliver to the indemnifying party a written notice of the commencement thereof. The indemnifying party shall have the right to participate in, and, to the extent the indemnifying
party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain
its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential conflict of interests
between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party 

  

 9 

 
within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party
of any liability to the indemnified party under this Section 1.7, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this
Section 1.7. 
 (d) Defect Eliminated in Final Prospectus. The foregoing indemnity agreements of the Company and Holders are
subject to the condition that, insofar as they relate to any Violation made in a preliminary prospectus but eliminated or remedied in the amended prospectus on file with the SEC at the time the registration statement in question becomes effective or
the amended prospectus filed with the SEC pursuant to SEC Rule 424(b) (the “Final Prospectus”), such indemnity agreement shall not inure to the benefit of any person if a copy of the Final Prospectus was furnished to the
indemnified party and was not furnished to the person asserting the loss, liability, claim or damage at or prior to the time such action is required by the Securities Act. 
 (e) Contribution. If the indemnification provided for in this Section 1.7 is held by a court of competent jurisdiction to be unavailable to
an indemnified party with respect to any loss, liability, claim, damage or expense referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by such indemnified
party with respect to such loss, liability, claim, damage or expense in the proportion that is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the statements or omissions that resulted
in such loss, liability, claim, damage or expense, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and the indemnified party shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party, and the parties’ relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission. In any such case, (A) no such Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and
sold by such Holder pursuant to such registration statement; and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or
entity who was not guilty of such fraudulent misrepresentation. 
 (f) Conflict with Underwriting Agreement. Notwithstanding the
foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions
in the underwriting agreement will control. 
 (g) Survival. The obligations of the Company and Holders under this Section 1.7
shall survive the completion of any offering of Registrable Securities in a registration statement, and otherwise. 
 1.8 Rule 144
Reporting. With a view to making available the benefits of certain rules and regulations of the Commission which may at any time permit the sale of the Registrable Securities to the public without registration, the Company agrees to:

 (a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act;

  

 10 

 (b) Use reasonable efforts to file with the Commission in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act; and 
 (c) So long as a Holder owns any Registrable
Securities, to furnish to the Holder forthwith upon request a written statement by the Company as to its compliance with the reporting requirements of said Rule 144, and of the Securities Act and the Exchange Act, a copy of the most recent
annual or quarterly report of the Company, and such other reports and documents of the Company as a Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing a Holder to sell any such securities without
registration. 
 1.9 Limitation on Sale of Registrable Securities. Notwithstanding the Holders’ rights pursuant to
Section 1.2 and 1.3 hereof (but without prejudice thereto), each Holder jointly and severally covenants and agrees that (i) no Registrable Securities may be sold pursuant to any registration statement filed under the Securities Act prior
to the six month anniversary of the date hereof and (ii) no more than one half of all Registrable Securities held by all Holders as a group may be sold pursuant to any registration statement filed under the Securities Act prior to the twelve
month anniversary of the date hereof. 
  

	 	2.	ASSIGNMENT AND AMENDMENT. 

 2.1
Assignment. Notwithstanding anything herein to the contrary: 
 (a) Registration Rights. The registration rights of a
Holder under Section 1 hereof may be assigned; provided, however that no party may assign any of the foregoing rights unless the Company is given written notice by the assigning party at the time of such assignment stating the
name and address of the assignee and identifying the securities of the Company as to which the rights in question are being assigned; and provided further that any such assignee shall receive such assigned rights subject to all the
terms and conditions of this Agreement, including without limitation the provisions of this Section 2. 
 2.2 Amendment and Waiver
of Rights. Any provision of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and
Holders (and/or any of their permitted successors or assigns) holding Series A Preferred representing and/or convertible into a majority of all the Holders’ Shares (as defined below); provided, further, that the grant to third

applicable to the Notes (as defined below), the “Indenture”), between the Company and the Trustee, providing for the issuance from time to time of one or more series of the Company’s securities. 
 WHEREAS, the Company desires and has requested the Trustee, pursuant to Section 8.1 of the Base Indenture, to join with it in the execution and
delivery of this First Supplemental Indenture in order to supplement the Base Indenture and to replace, where necessary, covenants in the Base Indenture as and to the extent set forth herein to provide for the issuance and the terms of the Notes.

 WHEREAS, Section 8.1 of the Base Indenture provides that a supplemental indenture may be entered into by the Company and the Trustee

similar to those set forth in this First Supplemental Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for a period of at least 20 Business Days following its
commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination of the Offer Period (the
“Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than
the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are made. 
  

 28 

 If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess
Proceeds for any purpose not otherwise prohibited by this First Supplemental Indenture. 
 If the Purchase Date is on or after an interest
record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to
Holders who tender Notes pursuant to the Asset Sale Offer. 
 Upon the commencement of an Asset Sale Offer, the Company will send, by first
class mail, a notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will
govern the terms of the Asset Sale Offer, will state: 
 (1) that the Asset Sale Offer is being made pursuant to this
Section 3.10 and Section 4.07 hereof and the length of time the Asset Sale Offer will remain open; 
 (2) the Offer
Amount, the purchase price and the Purchase Date; 
 (3) that any Note not tendered or accepted for payment will continue to
accrue interest; 
 (4) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to
the Asset Sale Offer will cease to accrue interest after the Purchase Date; 
 (5) that Holders electing to have a Note
purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in integral multiples of $1,000 only; 
 (6) that
Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry
transfer, to the Company, a Depositary, if appointed by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date; 
 (7) that Holders will be entitled to withdraw their election if the Company, the Depositary or the Paying Agent, as the case may be,
receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such
Holder is withdrawing his election to have such Note purchased; 
 (8) that, if the aggregate principal amount of Notes and
other pari passu Indebtedness surrendered by Holders thereof exceeds the Offer Amount, the Company will select the Notes and other pari passu Indebtedness to be purchased on a pro rata basis based on the principal amount of
Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes in denominations of $1,000, or integral multiples thereof, will be purchased); and 
 (9) that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of
the Notes surrendered (or transferred by book-entry transfer). 
  

 29 

 On or before the Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro
rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or cause to be delivered to the
Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.10. The Company, the Depositary
or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder and
accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such
Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the Holder thereof. The Company will publicly announce the results of the Asset
Sale Offer on the Purchase Date. 
 Other than as specifically provided in this Section 3.10, any purchase pursuant to this
Section 3.10 shall be made pursuant to the provisions of Sections 3.02 through 3.07 hereof.

 (16) Indebtedness consisting of Indebtedness issued by the Company or a Restricted Subsidiary to any current or former

clause (4) of Section 4.04(b) of this First Supplemental Indenture; 
 (17) Indebtedness owed on a short-term basis
of no longer than 30 days to banks and other financial institutions incurred in the ordinary course of business of the Company and its Restricted Subsidiaries with such banks or financial institutions that arises in connection with ordinary banking
arrangements to manage cash balances of the Company and its Restricted Subsidiaries; 
 (18) Indebtedness incurred by a
Restricted Subsidiary in connection with bankers’ acceptances, discounted bills of exchange or the discounting or factoring of receivables for credit management purposes, in each case incurred or undertaken in the ordinary course of business on
arm’s length commercial terms on a recourse basis; 
 (19) Indebtedness incurred by the Company or any of its Restricted
Subsidiaries constituting reimbursement obligations with respect to letters of credit issued in the ordinary course of business; provided, that upon the drawing of such letters of credit or the incurrence of such Indebtedness, such
obligations are reimbursed within 30 days following such drawing or incurrence; and 
 (20) the incurrence or issuance by the
Company or any Restricted Subsidiary of additional Indebtedness, Disqualified Stock or preferred stock in an aggregate principal amount (or accreted value or amount, as applicable) at any time outstanding, including all Permitted Refinancing
Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this clause (20), not to exceed the greater of (a) $250.0 million and (b) 5% of the consolidated total assets of the
Company and its Restricted Subsidiaries (measured at the time of such incurrence). 
 (c) The Company will not incur, and will not permit any
Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Guarantor unless such Indebtedness is also contractually subordinated in right of
payment to the Notes and the applicable Note Guarantee on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in right of payment to any other Indebtedness of the Company solely by
virtue of being unsecured or by virtue of being secured on a junior priority basis. 
 (d) For purposes of determining compliance with this
Section 4.06: 
 (1) in the event that an item of Indebtedness meets the criteria of more than one of the categories of
Permitted Debt described in clauses (1) through (20) of Section 4.06(b) or is entitled to be incurred pursuant to Section 4.06(a) of this Supplemental Indenture, the Company 

  

 39 

 
will be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of such item of Indebtedness, in
any manner that complies with this Section 4.06; 
 (2) at the time of incurrence, the Company will be entitled to divide
and classify an item of Indebtedness in more than one of the types of Indebtedness described in Sections 4.06(a) and (b) of this First Supplemental Indenture; 
 (3) Indebtedness under the Credit Agreement outstanding on the date on which Notes are first issued and authenticated under this First
Supplemental Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of Section 4.06(b); 
 (4) Guarantees of, or obligations in respect of letters of credit relating to, Indebtedness which is otherwise included in the
determination of a particular amount of Indebtedness shall not be included; and 
 (5) with respect to any U.S.
dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date
such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign
currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction
shall be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. 
 (e) The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of
additional Indebtedness with the same terms, the reclassification of preferred stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified Stock in the form of additional shares of the same class of
Disqualified Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Stock for purposes of Section 4.06 of this First Supplemental Indenture; provided, in each such case, that the amount of any such accrual,
accretion or payment is included in Consolidated Interest Expense of the Company as accrued. Notwithstanding any other provision of this Section 4.06, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur
pursuant to Section 4.06 of this First Supplemental Indenture shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 
 (f) The amount of any Indebtedness outstanding as of any date will be: 
 (1) the accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount; 
 (2) the principal amount of the Indebtedness, in the case of any other Indebtedness; and 
  

 40 

 (3) in respect of Indebtedness of another Person secured by a Lien on the assets of the
specified Person, the lesser of: 
 (a) the Fair Market Value of such assets at the date of determination; and 
 (b) the amount of the Indebtedness of the other Person. 
 Section 4.07 Asset Sales. 
 (a) The Company will not, and will not permit any of its Restricted
Subsidiaries to, consummate an Asset Sale unless: 
 (1) the Company (or the Restricted Subsidiary, as the case may be)
receives consideration at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or sold or otherwise disposed of; and 
 (2) at least 75% of the consideration received in the Asset Sale by the Company or such Restricted Subsidiary is in the form of cash or
Cash Equivalents. For purposes of this provision, each of the following will be deemed to be cash: 
 (A) any liabilities, as
shown on the most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantee) that are assumed by the
transferee of any such assets; 
 (B) any securities, notes or other obligations received by the Company or any such
Restricted Subsidiary from such transferee that are, within 180 days following the closing of the related Asset Sale, converted by the Company or such Restricted Subsidiary into cash or Cash Equivalents, to the extent of the cash or Cash Equivalents
received in that conversion; 
 (C) any stock or assets of the kind referred to in clauses (5), (6) or (7) of
Section 4.07(b) of this First Supplemental Indenture; and 
 (D) any Designated Non-cash Consideration received by the
Company or such Restricted Subsidiary having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (D) that is at that time outstanding (with the Fair Market Value of
each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value), not to exceed 5% of the consolidated total assets of the Company and its Restricted Subsidiaries (measured
at the time of the receipt of such Designated Non-cash Consideration). 
 (b) Within 450 days after the receipt of any Net Proceeds from an
Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply an amount equal to such Net Proceeds: 
 (1) to repay Indebtedness and other Obligations under a Credit Facility and any other Indebtedness that is secured by a Lien and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce
commitments with respect thereto; 
 (2) to repay Indebtedness and other Obligations of a Restricted Subsidiary that is not a
Guarantor, other than Indebtedness owed to the Company or another Restricted Subsidiary; 
  

 41 

 (3) to repurchase, redeem or defease Existing Indebtedness which has a final maturity
date (as in effect on the Issue Date) on or prior to January 15, 2016; 
 (4) to repay other Indebtedness of the Company
(other than any Disqualified Stock or any Indebtedness that is contractually subordinated to the Notes), other than Indebtedness owed to a Restricted Subsidiary of the Company); provided that the Company shall equally and ratably repay the
Notes as provided under Section 3.08 of this First Supplemental Indenture through open market purchases (to the extent such purchases are at or above 100% of the principal amount thereof) or by making an offer (in accordance with the procedures
set forth below for an Asset Sale Offer) to all Holders to purchase the Notes at 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any, on the amount of Notes that would otherwise be prepaid; 
 (5) to acquire all or substantially all of the assets of, or any Capital Stock of, another Permitted Business, if, after giving effect to
any such acquisition of Capital Stock, the Permitted Business is or becomes a Restricted Subsidiary of the Company; 
 (6) to
make a capital expenditure; or 
 (7) to acquire other assets that are used or useful in a Permitted Business, 
 or enter into a binding commitment regarding clauses (5), (6) or (7) above, provided that if such acquisition or expenditure in respect of such binding
commitment is not consummated on or before the 180th day following the aforementioned 450 day period, and the Company or such Restricted Subsidiary shall not have otherwise applied an amount equal to such Net Proceeds pursuant to clause
(1)-(7) of this Section 4.07(b) on or before such 180th day, such binding commitment shall be deemed not to have been a permitted application of Net Proceeds. 
 (c) The Company will not, and will not permit any Restricted Subsidiary to, engage in any Asset Swap unless, in the event such Asset Swap involves the transfer by the Company or any Restricted Subsidiary of assets
having an aggregate Fair Market Value in excess of $50.0 million, the terms of such Asset Swap have been approved by a majority of the members of the Board of Directors of the Company. 
 (d) Pending the final application of an amount equal to any Net Proceeds, the Company may temporarily reduce revolving credit borrowings or otherwise
invest the Net Proceeds in any manner that is not prohibited by this First Supplemental Indenture. 
 (e) Any Net Proceeds from Asset Sales
that are not applied or invested as provided in Section 4.07(b) of this First Supplemental Indenture will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $100.0 million, within five days
thereof, the Company will make an Asset Sale Offer to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this First Supplemental Indenture with respect to offers to
purchase or redeem with the proceeds of sales of assets to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price in any Asset Sale Offer will be equal
to 100% of the principal amount, plus accrued and unpaid interest to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company may use those Excess Proceeds for any
purpose not otherwise prohibited by this First Supplemental Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee will select
the Notes and such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero. 
  

 42 

 (f) The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to a Change of Control Offer or an Asset Sale Offer. To the extent that the provisions of any
securities laws or regulations conflict with Section 4.07 or Section 4.11 of this First Supplemental Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its
obligations under either such Section by virtue of such compliance. 
 Section 4.08 Transactions with Affiliates. 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise dispose of
any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate of the Company
involving aggregate payments of consideration in excess of $25.0 million (each, an “Affiliate Transaction”), unless: 
 (1) the Affiliate Transaction is on terms that are not materially less favorable to the Company or the relevant Restricted Subsidiary than those that would have been obtained in a comparable transaction by the Company
or such Restricted Subsidiary with an unrelated Person; and 
 (2) in the event of any Affiliate Transaction or series of
related Affiliate Transactions involving the transfer by the Company or any Restricted Subsidiary of assets having an aggregate Fair Market Value in excess of $50.0 million, the terms of such Affiliate Transaction have been approved by a majority of
the members of the Board of Directors of the Company and by a majority of the disinterested members of the Board of Directors of the Company. 
 (b) The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to Section 4.08(a) of this First Supplemental Indenture: 
 (1) any agreement, arrangement or transaction with a current or former officer, director, employee or consultant of the Company or any of
its Restricted Subsidiaries relating to compensation, perquisites or indemnities, including without limitation any employment agreement, employee benefit plan, officer or director indemnification agreement, consultant agreement or any similar
arrangement, entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of business and payments pursuant thereto; 
 (2) transactions between or among the Company and/or its Restricted Subsidiaries; 
 (3)
transactions with a Person (other than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company solely because the Company owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

 (4) any issuance of Equity Interests (other than Disqualified Stock) of the Company to Affiliates of the Company;

  

 43 

 (5) Restricted Payments that do not violate the provisions of Section 4.04 of this
First Supplemental Indenture or are permitted pursuant to the definition of Permitted Investments; 
 (6) sales or other
transfers or dispositions of accounts receivable and other related assets customarily transferred in an asset securitization transaction involving accounts receivable to a Receivables Subsidiary in a Qualified Receivables Transaction and
transactions between a Receivables Subsidiary and any Person in which the Receivables Subsidiary has an Investment; 
 (7)
loans or advances to, or Guarantees of Indebtedness of, employees, officers or directors made in the ordinary course of business of the Company or any Restricted Subsidiary of the Company in an aggregate amount not in excess of $15.0 million with
respect to all loans, advances or Guarantees made since the Issue Date; 
 (8) transaction or series of related transactions
in which the Company or any Restricted Subsidiary delivered to the Trustee a letter issued by an accounting, appraisal or investment banking firm of national standing as to the fairness to the Company or such Restricted Subsidiary of such
transaction or series of related transactions from a financial point of view or that such transaction or series of related transactions are not materially less favorable to the Company or the relevant Restricted Subsidiary, taken as a whole, than
those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; 
 (9) transactions with customers, clients, suppliers or purchasers or sellers of goods or services, in each case in the ordinary course of the business of the Company and its Restricted Subsidiaries and otherwise in
compliance with the terms of this First Supplemental Indenture; provided that in the reasonable determination of the Company, such transactions are on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than
those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person; 
 (10) payments by the Company and its Restricted Subsidiaries pursuant to tax sharing agreements among the Company and its Restricted Subsidiaries on customary terms to the extent attributable to the ownership or
operation of the Company and its Restricted Subsidiaries; and 
 (11) any agreement as in effect as of the Issue Date, or any
amendment thereto (so long as any such amendment is not disadvantageous to the Holders when taken as a whole as compared to the applicable agreement as in effect on the Issue Date). 
 Section 4.09 Liens. 
 The Company will not, and will not permit any of its Restricted
Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than Permitted Liens) upon any of their property or assets, now owned or hereafter acquired, unless all payments due under
this First Supplemental Indenture and the Notes and any Note Guarantee are secured on an equal and ratable basis with the obligations so secured until such time as such obligations are no longer secured by a Lien. 
 Section 4.10 Corporate Existence. 
 Subject to
Article 5 hereof, the Company shall do or cause to be done all things necessary to preserve and keep in full force and effect: 
 (1) its corporate existence, and the corporate, partnership or other existence of each of its Guarantors, in accordance with the respective organizational documents (as the same may be amended from time to time) of the Company or any such
Guarantor; and 
  

 44 

 (2) the rights (charter and statutory), licenses and franchises of the Company and its
Guarantors. 
 Section 4.11 Offer to Repurchase Upon Change of Control. 
 (a) If a Change of Control occurs, each Holder of Notes will have the right to require the Company to repurchase all or any part (equal to $2,000 or an
integral multiple of $1,000 in excess thereof) of that Holder’s Notes at a purchase price equal to 101% of the aggregate principal amount of the Notes, plus accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase,
subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date (a “Change of Control Payment”). 
 Within 30 days following any Change of Control, the Company will mail a notice to each Holder (the “Change of Control Offer”):

 (1) describing the transaction or transactions that constitute the Change of Control; and offering to repurchase such
Holder’s Notes at a purchase price equal to the Change of Control Payment; and 
 (2) stating the repurchase date, which
date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”). 
 The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with
the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of this First Supplemental Indenture, the Company will comply with
the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of this First Supplemental Indenture by virtue of such compliance. 
 (b) On the Change of Control Payment Date, the Company will, to the extent lawful: 
 (1) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control Offer; 
 (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly
tendered; and 
 (3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an
Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
 The Paying
Agent will promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note equal in
principal amount to any unpurchased portion of the Notes surrendered, if any. 
  

 45 

 (c) Notwithstanding anything to the contrary contained herein, the Company will not be required to make a
Change of Control Offer upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this First Supplemental Indenture applicable to a
Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 3.08 of this First Supplemental
Indenture unless and until there is a default in payment of the applicable redemption price. 
 (d) Notwithstanding anything to the contrary
contained herein, a Change of Control Offer may be made in advance of a Change of Control, conditional upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making of the
Change of Control Offer. 
 Section 4.12 Future Subsidiary Guarantees. 
 The Company will not permit any of its current or future Domestic Subsidiaries (other than Receivables Subsidiaries), directly or indirectly, to Guarantee
or pledge any assets to secure the payment of any Ineligible Indebtedness of any other Person or otherwise provide direct credit support for any Ineligible Indebtedness of any other Person, or to incur any Ineligible Indebtedness as primary obligor,
in each case, unless such Domestic Subsidiary within 60 days executes and delivers a supplemental indenture providing for the Guarantee of the payment of the Notes by such Domestic Subsidiary, which Guarantee will be senior to or pari passu with
such Domestic Subsidiary’s Guarantee, pledge, credit support or Ineligible Indebtedness, as the case may be. 
 The Note Guarantee of a
Guarantor will automatically and unconditionally be released: 
 (1) in connection with any sale or other disposition of all
or substantially all of the assets of that Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale
or other disposition does not violate Section 4.07 of this First Supplemental Indenture; 
 (2) in connection with any
sale or other disposition of all of the Capital Stock of that Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary of the Company, if the sale or other disposition does
not violate Section 4.07 of this First Supplemental Indenture and the Guarantor ceases to be a Restricted Subsidiary of the Company as a result of such sale or other disposition; 
 (3) if the Company designates any Restricted Subsidiary that is a Guarantor to be an Unrestricted Subsidiary in accordance with the
applicable provisions of this First Supplemental Indenture; 
 (4) upon the release or discharge of the Guarantee, pledge,
credit support or Indebtedness that resulted in the creation of such Note Guarantee; or 
 (5) upon legal or covenant
defeasance or satisfaction and discharge as provided in Article 7 or Article 9 of this First Supplemental Indenture. 
  

 46 

 Section 4.13 Designation of Restricted and Unrestricted Subsidiaries. 
 The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a
Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in the Subsidiary designated as Unrestricted will be
deemed to be an Investment made as of the time of the designation and will reduce the amount available for Restricted Payments under Section 4.04 of this First Supplemental Indenture or under one or more clauses of the definition of Permitted
Investments, as determined by the Company. That designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets the definition of an Unrestricted Subsidiary. The Board of
Directors of the Company may redesignate any Unrestricted Subsidiary to be a Restricted Subsidiary if that redesignation would not cause a Default. 
 Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee a certified copy of a resolution of the Board of Directors giving effect to such designation and an
Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 4.04 of this First Supplemental Indenture or under one or more clauses of the definition of Permitted Investments.
If, at any time, any Unrestricted Subsidiary would fail to meet the preceding requirements as an Unrestricted Subsidiary, it will thereafter cease to be an Unrestricted Subsidiary for purposes of this First Supplemental Indenture and any
Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of the Company as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 4.06 of this First Supplemental
Indenture, the Company will be in default of such Section. 
 The Board of Directors of the Company may at any time designate any
Unrestricted Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted
Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under Section 4.06 of this First Supplemental Indenture calculated on a pro forma basis as if such designation had occurred at the beginning of
the four-quarter reference period or the Company would have an Interest Coverage Ratio greater than the Interest Coverage Ratio for the Company immediately prior to such designation; and (2) no Default or Event of Default would be in existence
following such designation. 
 Section 4.14 Changes in Covenants When Notes Rated Investment Grade 
 If on any date following the Issue Date: 
 (1) the Notes are rated (i) Baa3 or better by Moody’s and BB+ or better by S&P or (ii) Ba1 or better by Moody’s and BBB- or better by S&P (or, if either such entity ceases to rate the Notes
for reasons outside of the Company’s control, the equivalent investment grade credit rating from any other “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act
selected by the Company as a replacement agency); and 
 (2) no Default or Event of Default shall have occurred and be
continuing, 
 then, beginning on such date and continuing at all times thereafter regardless of any subsequent changes in the rating of the
Notes, the covenants contained in Sections 4.04, 4.05, 4.06, 4.07, 4.08, 4.12, 4.13, and 5.02(a)(4) of this First Supplemental Indenture will no longer be applicable to the Notes.

applicable four-quarter period, (i) be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Interest Coverage Ratio test set forth in Section 4.06(a) of this First Supplemental Indenture or (ii) have had an

purpose of reorganizing the Company in another jurisdiction; or 
 (2) any consolidation or merger, or any sale, assignment,
transfer, conveyance, lease or other disposition of assets between or among the Company and its Restricted Subsidiaries.

 (7) failure by the Company or any of its Significant Subsidiaries to pay final judgments with respect to which no appeal may be or has been taken, entered by a court or courts of competent jurisdiction aggregating in excess of $50.0 million

an enforcement proceeding has been commenced by any creditor upon such judgment or decree which is not promptly stayed; 
 (8)
except as permitted by this First Supplemental Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf
of any Guarantor, denies or disaffirms its obligations under its Note Guarantee; 
 (9) the Company or any of its Restricted

Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary in an involuntary case; 
 (B)
appoints a custodian of the Company or any of its Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary or for all or

Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary; 
 and the order or decree remains unstayed and in effect for 60 consecutive days. 
 (b) In the event of any Event of Default
specified in clause (6) of Section 6.02(a) hereof, such Event of Default and all consequences thereof shall be annulled, waived and rescinded automatically and without any action by the Trustee or the Holders if, within 20 days after such
Event of Default arose, 
 (1) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged;

 (2) the Holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to

Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further action or notice. If any other Event of Default occurs and is
continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately; provided that so long as any Indebtedness permitted to be incurred
pursuant to this First Supplemental Indenture under any Credit Facility is outstanding, such acceleration will not be effective until the earlier of: (1) the acceleration of such Indebtedness under such Credit Facility; or (2) five
Business Days after the giving of written notice of such acceleration to the Company and the administrative agent (or any other agent or representative) with respect to such Credit Facility. 
 Upon any such declaration, the Notes shall become due and payable immediately. 
 The Holders of a majority in aggregate principal amount of the then outstanding Notes by written notice to the Trustee may, on behalf of all of the
Holders, rescind an acceleration and its consequences, if the rescission would not conflict with any judgment or decree and if all existing Events of Default (except nonpayment of principal, interest or premium that has become due solely because of
the acceleration) have been cured or waived and funds sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other reasonable expenses and liabilities incurred, and all reasonable advances made, by the
Trustee except as a result of negligence or bad faith, shall have been deposited with the Trustee.

 ARTICLE 7 
 LEGAL DEFEASANCE AND COVENANT DEFEASANCE 
 Section 7.01 Base Indenture 
 Section 10.3 of the Base Indenture shall not apply to the Notes and hereafter shall be void and of no force and effect except solely with respect to
any other series of Securities issued under the Base Indenture; and, insofar as relating to the Notes, any reference to Section 10.3 in the Base Indenture shall instead be deemed to refer to Section 7.05 of this First Supplemental
Indenture. 
 Section 7.02 Option to Effect Legal Defeasance or Covenant Defeasance. 
 The Company may at any time, at the option of its Board of Directors evidenced by a resolution set forth in an Officers’ Certificate, elect to have
either Section 7.03 or 7.04 hereof be applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 7. 
 Section 7.03 Legal Defeasance and Discharge. 
 (a) Upon the Company’s exercise under Section 7.02 hereof of
the option applicable to this Section 7.03, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 7.05 hereof, be deemed to have been discharged from their obligations with respect
to all outstanding Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Guarantors will
be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding” only for the purposes of Section 7.06 hereof and
the other Sections of this First Supplemental Indenture referred to in clauses (1) and (2) below, and to have satisfied all their other obligations under such Notes, the Note Guarantees and this First Supplemental Indenture (and the
Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the clauses (1) to (4) of this Section 7.03(a) which will survive until otherwise terminated or discharged
hereunder: 
 (1) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest
or premium, if any, on, such Notes when such payments are due from the trust referred to in Section 7.06 hereof; 
 (2)
the Company’s obligations with respect to such Notes under Article 2 of this First Supplemental Indenture; 
 (3) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and the Guarantors’ obligations in connection therewith; and 
 (4) this Article 7 (excluding the provisions of this Article 7 with respect to Covenant Defeasance). 
 (b) Subject to compliance with this Article 7, the Company may exercise its option under this Section 7.03 notwithstanding the prior exercise of its
option under Section 7.04 hereof. 
  

 52 

 Section 7.04 Covenant Defeasance. 
 Upon the Company’s exercise under Section 7.02 hereof of the option applicable to this Section 7.04, the Company and each of the Guarantors
will, subject to the satisfaction of the conditions set forth in Section 7.05 hereof, be released from each of their obligations under the covenants contained in Sections 4.04, 4.05, 4.06, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12 and 4.13 hereof and
clause (4) of Section 5.02(a) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 7.05 hereof are satisfied (hereinafter, “Covenant Defeasance”), and the Notes will
thereafter be deemed not “outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed
“outstanding” for all other purposes hereunder (it being understood that such Notes will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note
Guarantees, the Company and the Guarantors may omit to comply with and will have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein
to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply will not constitute a Default or an Event of Default under Section 6.02 hereof, but,
except as specified above, the remainder of this First Supplemental Indenture and such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 7.02 hereof of the option applicable to
this Section 7.04, subject to the satisfaction of the conditions set forth in Section 7.05 hereof, Sections 6.02(a)(3) through 6.02(a)(8) hereof will not constitute Events of Default. 
 Section 7.05 Conditions to Legal or Covenant Defeasance. 
 In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 7.02 or 7.04 hereof: 
 (1) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion
of a nationally recognized investment bank, appraisal firm, or firm of independent public accountants, to pay the principal of, premium, if any, and interest on, the outstanding Notes on the stated date for payment thereof or on the applicable
redemption date, as the case may be, and the Company must specify whether the Notes are being defeased to such stated date for payment or to a particular redemption date; 
 (2) in the case of an election under Section 7.03 hereof, the Company must deliver to the Trustee an Opinion of Counsel confirming
that: 
 (A) the Company has received from, or there has been published by, the Internal Revenue Service a ruling; or

 (B) since the date of this First Supplemental Indenture, there has been a change in the applicable federal income tax law,

 in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Notes will
not recognize income, gain or loss for federal income tax purposes as a result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal
Defeasance had not occurred; 
  

 53 

 (3) in the case of an election under Section 7.04 hereof, the Company must deliver
to the Trustee an Opinion of Counsel confirming that, subject to customary assumptions and exclusions, the Holders of the outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant
Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred; 
 (4) no Default or Event of Default shall have occurred and be continuing on the date of such deposit (other than a Default or Event of
Default resulting from the borrowing of funds to be applied to such deposit or the granting of Liens in connection therewith); 
 (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this First Supplemental Indenture) to which the Company or any of
its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit or the granting of Liens in connection therewith);

 (6) the Company must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the
Company with the intent of preferring the Holders over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others; and 
 (7) the Company must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, which opinion may be subject to
customary assumptions and exclusions, each stating that all conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with. 
 Section 7.06 Deposited Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions. 
 Subject to Section 7.07 hereof, all money and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this
Section 7.06, the “Trustee”) pursuant to Section 7.05 hereof in respect of the outstanding Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this First Supplemental
Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal,
premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 
 The Company
will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant to Section 7.05 hereof or the principal and interest received in respect
thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes. 
 Notwithstanding anything in this Article 7 to the contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or non-callable Government Securities held by it as provided in
Section 7.05 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 7.05(1)
hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance. 
  

 54 

 Section 7.07 Repayment to Company. 
 Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or
interest on, any Note and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) will be discharged from such
trust; and the Holder of such Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee
thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in the New York Times and The Wall Street
Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining
will be repaid to the Company. 
 Section 7.08 Reinstatement. 
 If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with Section 7.03 or 7.04 hereof, as the case may be, by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the Guarantors’ obligations under this First Supplemental Indenture and the Notes and the Note Guarantees will be
revived and reinstated as though no deposit had occurred pursuant to Section 7.03 or 7.04 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 7.03 or 7.04 hereof, as the
case may be; provided, however, that, if the Company makes any payment of principal of, premium, if any, or interest on, any Note following the reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of
such Notes to receive such payment from the money held by the Trustee or Paying Agent. 
 ARTICLE 8 
 AMENDMENT, SUPPLEMENT AND WAIVER 
 Section 8.01 Base
Indenture. 
 Article 8 of the Base Indenture shall not apply to the Notes and hereafter shall be void and of no force and effect except
solely with respect to any other series of Securities issued under the Base Indenture; and, insofar as relating to the Notes, any reference to Article 8 in the Base Indenture shall instead be deemed to refer to Article 8 of this First Supplemental
Indenture. 
 Section 8.02 Without Consent of Holders. 
 Notwithstanding Section 8.03 of this First Supplemental Indenture, the Company, the Guarantors and the Trustee may amend or supplement this First Supplemental Indenture or the Notes or the Note Guarantees without
the consent of any Holders: 
 (1) to cure any ambiguity, defect or inconsistency; 
 (2) to provide for uncertificated Notes in addition to or in place of certificated Notes; 
  

 55 

 (3) to provide for the assumption of the Company’s or a Guarantor’s obligations
to the Holders of the Notes and Note Guarantees in the case of a merger or consolidation or sale of all or substantially all of the Company’s or such Guarantor’s assets, as applicable; 
 (4) to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect
the legal rights hereunder of any Holder or surrender any right or power conferred upon the Company; 
 (5) to comply with
requirements of the SEC in order to effect or maintain the qualification of this First Supplemental Indenture under the Trust Indenture Act; 
 (6) to conform the text of this First Supplemental Indenture or the Notes to any provision of the “Description of Notes” section of the Company’s Prospectus Supplement dated December 6, 2007,
relating to the initial offering of the Notes, to the extent that such provision in that “Description of Notes” was intended (as evidenced by an Officer’s Certificate) to be a verbatim recitation of a provision of this First
Supplemental Indenture, the Note Guarantees or the Notes; 
 (7) to provide for the issuance of additional notes of the same
series in accordance with the limitations set forth in this First Supplemental Indenture as of the Issue Date; or 
 (8) to
provide for the appointment of a successor trustee; provided that the successor trustee is otherwise qualified and eligible to act as such under the terms of this First Supplemental Indenture; or 
 (9) to provide a guarantee with respect to the Notes or to grant any Lien for the benefit of the Holders of the Notes. 
 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the execution of any such amended or supplemental
indenture, and upon receipt by the Trustee of the documents described in Section 6.2 of the Base Indenture, the Trustee will join with the Company and the Guarantors in the execution of any amended or supplemental indenture authorized or
permitted by the terms of this First Supplemental Indenture and to make any further appropriate agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture
that affects its own rights, duties or immunities under this First Supplemental Indenture or otherwise. 
 Section 8.03 With Consent of Holders.

 Except as provided below in this Section 8.03, the Company and the Trustee may amend or supplement this First Supplemental Indenture
and the Notes and the Note Guarantees with the consent of the Holders of at least a majority in aggregate principal amount of the then Outstanding Notes voting as a single class (including, without limitation, consents obtained in connection with a
tender offer or exchange offer for, or purchase of, the Notes), and, subject to Sections 5.7 and 5.10 of the Base Indenture, any existing Default or Event of Default (other than a Default or Event of Default in the payment of the principal of,
premium or interest on, the Notes, except a payment default resulting from an acceleration that has been rescinded) or compliance with any provision of this First Supplemental Indenture or the Notes or the Note Guarantees may be waived with the
consent of the Holders of a majority in aggregate principal amount of the then Outstanding Notes voting as a single class (including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the
Notes). 
  

 56 

 Upon the request of the Company accompanied by a resolution of its Board of Directors authorizing the
execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in
Section 6.2 of the Base Indenture, the Trustee will join with the Company and the Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own
rights, duties or immunities under this First Supplemental Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture. 
 It is not necessary for the consent of the Holders under this Section 8.03 to approve the particular form of any proposed amendment, supplement or
waiver, but it is sufficient if such consent approves the substance thereof. 
 After an amendment, supplement or waiver under this
Section 8.03 becomes effective, the Company will mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will not, however, in
any way impair or affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 5.7 and 5.10 of the Base Indenture, the Holders of a majority in aggregate principal amount of the Notes then Outstanding voting as a
single class may waive compliance in a particular instance by the Company with any provision of this First Supplemental Indenture or the Notes or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or
waiver under this Section 8.03 may not (with respect to any Notes held by a non-consenting Holder): 
 (1) reduce the
principal amount of Notes whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce the principal of or
change the fixed maturity of any Note or alter or waive any of the provisions with respect to the redemption of the Notes (except as provided above with respect to Sections 3.10, 4.07 and 4.11 hereof); 
 (3) reduce the rate of or change the time for payment of interest, including default interest, on any Note; 
 (4) waive a Default or Event of Default in the payment of principal of, or premium, if any, or interest on, the Notes (except a rescission
of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then Outstanding Notes and a waiver of the payment default that resulted from such acceleration); 
 (5) make any Note payable in money other than that stated in the Notes; 
 (6) make any change in the provisions of this First Supplemental Indenture relating to waivers of past Defaults or the rights of Holders
to receive payments of principal of, or interest or premium, if any, on, the Notes; 
 (7) waive a redemption payment with
respect to any Note (other than a payment required by Sections 3.10, 4.07 or 4.11 hereof); 
 (8) release any Guarantor from
any of its obligations under its Note Guarantee or this First Supplemental Indenture, except in accordance with the terms of this First Supplemental Indenture; or 
 (9) make any change in the preceding amendment and waiver provisions. 
  

 57 

 Section 8.04 Compliance with Trust Indenture Act. 
 Every amendment or supplement to this First Supplemental Indenture or the Notes will be set forth in an amended or supplemental indenture that complies
with the Trust Indenture Act as then in effect. 
 Section 8.05 Revocation and Effect of Consents. 
 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note may
revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver becomes effective in accordance with its terms and
thereafter binds every Holder. 
 Section 8.06 Notation on or Exchange of Notes. 
 The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for
all Notes may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver. 
 Failure to make the
appropriate notation or issue a new Note will not affect the validity and effect of such amendment, supplement or waiver. 
 Section 8.07 Trustee to
Sign Amendments, etc. 
 The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 8 if the
amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. The Company may not sign an amended or supplemental indenture until the Board of Directors of the Company approves it. In executing any
amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 6.1 of the Base Indenture) will be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that the
execution of such amended or supplemental indenture is authorized or permitted by this First Supplemental Indenture. 
 ARTICLE 9 

SATISFACTION AND DISCHARGE 
 Section 9.01 Base
Indenture 
 Sections 10.1 and 10.2 of the Base Indenture shall not apply to the Notes and hereafter shall be void and of no force and
effect except solely with respect to any other series of Securities issued under the Base Indenture as at the time supplemented and modified under the express terms of which series such Section is to be applicable; and, insofar as relating to the
Notes, any reference to Section 10.1 or Section 10.3 in the Base Indenture shall instead be deemed to refer to Section 9.02 and 9.03, respectively, of this First Supplemental Indenture. 
  

 58 

 Section 9.02 Satisfaction and Discharge. 
 This First Supplemental Indenture will be discharged and will cease to be of further effect as to all Notes issued hereunder, when: 
 (1) either: 
 (a) all Notes
that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment money has theretofore been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee
for cancellation; or 
 (b) all Notes that have not been delivered to the Trustee for cancellation have become due and payable
by reason of the mailing of a notice of redemption or otherwise or will become due and payable within one year and the Company or any Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for
the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and discharge the entire
Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued interest to the date of maturity or redemption; 
 (2) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default
resulting from the borrowing of funds to be applied to such deposit and the granting of Liens in connection therewith) and the deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the
Company or any Guarantor is a party or by which the Company or any Guarantor is bound (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the granting of Liens in connection therewith;

 (3) the Company or any Guarantor has paid or caused to be paid all sums payable by it under this First Supplemental
Indenture; and 
 (4) the Company has delivered irrevocable instructions to the Trustee under this First Supplemental
Indenture to apply the deposited money toward the payment of the Notes at maturity or on the redemption date, as the case may be. 
 In addition, the Company
must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied. 
 Notwithstanding the satisfaction and discharge of this First Supplemental Indenture, if money has been deposited with the Trustee pursuant to subclause
(b) of clause (1) of this Section 9.02, the provisions of Sections 9.03 and 7.07 hereof will survive. In addition, nothing in this Section 9.02 will be deemed to discharge those provisions of Section 6.6 of the Base
Indenture, that, by their terms, survive the satisfaction and discharge of this First Supplemental Indenture. 
 Section 9.03 Application of Trust
Money. 
 Subject to the provisions of Section 7.07 hereof, all money deposited with the Trustee pursuant to Section 9.02 hereof
shall be held in trust and applied by it, in accordance with the provisions of the Notes and this First Supplemental Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons 

  

 59 

 
entitled thereto, of the principal (and premium, if any) and interest for whose payment such money has been deposited with the Trustee; but such money need
not be segregated from other funds except to the extent required by law. 
 If the Trustee or Paying Agent is unable to apply any money or
Government Securities in accordance with Section 9.02 hereof by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the
Company’s and any Guarantor’s obligations under this First Supplemental Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 9.02 hereof; provided that if the Company has made
any payment of principal of, premium, if any, or interest on, any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government
Securities held by the Trustee or Paying Agent.

 INTEREST. Unisys
Corporation, a Delaware corporation (the “Company”), promises to pay interest on the principal amount of this Note at 12.5% per annum from
                     until maturity. The Company will pay interest semi-annually in arrears on January 15 and July 15 of each year,
or if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). Interest on the Notes will accrue from the most recent date to which interest has been paid or, if no interest has
been paid, from the date of issuance; provided that if there is no existing Default in the payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest Payment
Date, interest shall accrue from such next succeeding Interest Payment Date; provided further that the first Interest Payment Date shall be
                    . Interest will be computed on the basis of a 360-day year of twelve 30-day months. 
 METHOD OF PAYMENT. The Company will pay interest on the Notes (except
defaulted interest) to the Persons who are registered Holders at the close of business on the January 1 or July 1 next preceding the Interest Payment Date, even if such Notes are canceled after such

The Company issued the Notes under an Indenture dated as of March 1, 2003, (the “Base Indenture”) between the Company and the Trustee, as supplemented by a First Supplemental Indenture, dated as of December 11, 2007
(the “First Supplemental Indenture”) (the Base Indenture as supplemented by the First Supplemental Indenture and any other supplemental indenture applicable to the Notes, the “Indenture.”) The terms of the Notes
include those stated in the Base Indenture, the First Supplemental Indenture and those made a part of each thereof by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Base Indenture and
the First Supplemental Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the First Supplemental Indenture, the provisions of the First Supplemental Indenture shall
govern and be controlling. The Notes are unsecured obligations of the Company. The First Supplemental Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder. 
 OPTIONAL REDEMPTION. 
 At any time prior to January 15, 2011, the Company may on any one or more occasions redeem up to 35% of the aggregate principal
amount of Notes issued under the First Supplemental Indenture, upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 112.5% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of
redemption (subject to the rights of Holders on the relevant record date to receive interest on the relevant interest payment date), with the net cash proceeds from one or more Equity Offerings; provided that at least 50% in aggregate
principal amount of the Notes originally issued under the First Supplemental Indenture (excluding Notes held by the Company and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption and that such redemption occurs
within 180 days of the date of the closing of such Equity Offering. 
 At any time prior to January 15, 2012, the Company
may on one or more occasions redeem all or a part of the Notes, upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of Notes redeemed, plus the Applicable Premium as of, and accrued

a part of the Notes upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest, if any, on the Notes redeemed to the applicable
redemption date, if redeemed during the twelve-month period beginning on January 15 of the years indicated below, subject to the rights of Holders on the relevant record date to receive interest on the relevant interest payment date:

Indenture. 
 NOTICE OF REDEMPTION. Notice of redemption
will be mailed at least 30 days but not more than 60 days before the redemption date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date
if the notice is issued in connection with a defeasance of the Notes or a satisfaction or discharge of the First Supplemental Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000, unless
all of the Notes held by a Holder are to be redeemed.

Indenture. The Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the
transfer of any Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date.

 AMENDMENT, SUPPLEMENT AND
WAIVER. Subject to certain exceptions, the First Supplemental Indenture or the Notes or the Note Guarantees may be amended or supplemented with the consent of the Holders of at least a majority in aggregate
principal amount of the then outstanding Notes voting as a single class, and any existing Default or Event or Default or compliance with any provision of the First Supplemental Indenture or the Notes or the Note Guarantees may be waived with the
consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes voting as a single class. 
 Without the consent of any Holder of a Note, the First Supplemental Indenture or the Notes or the Note Guarantees may be amended or supplemented to cure any ambiguity, defect or inconsistency, to provide for uncertificated Notes in addition
to or in place of certificated Notes, to provide for the assumption of the Company’s or a Guarantor’s obligations to Holders of the Notes and Note Guarantees in case of a merger or consolidation or sale of all or substantially all of the
Company’s or such Guarantor’s assets, as applicable, to make any change that would provide any additional rights or benefits to the Holders of the Notes or that does not adversely affect the legal rights under the First Supplemental
Indenture of any such Holder or surrender any right or power conferred upon the Company, to comply with the requirements of the SEC in order to effect or maintain the qualification of the First Supplemental Indenture under the Trust Indenture Act,
to conform the text of the First Supplemental Indenture or the Notes to any provision of the “Description of Notes” section of the Company’s Prospectus Supplement dated December 6, 2007, relating to the initial offering of the
Notes, to the extent that such provision in that “Description of Notes” was intended (as evidenced by an Officer’s Certificate) to be a verbatim recitation of a provision of the First Supplemental Indenture, the Note Guarantees or the
Notes; to provide for the issuance of additional notes of the same series in accordance with the limitations set forth in the First Supplemental Indenture as of the Issue Date, to provide for the appointment of a successor trustee (provided
that the successor trustee is otherwise qualified and eligible to act as such under the terms of the First Supplemental Indenture); or to provide a guarantee with respect to the Notes or to grant any Lien for the benefit of the Holders of the Notes.

 DEFAULTS AND REMEDIES. Events of Default include:
(i) default for 30 days in the payment when due of interest on the Notes; (ii) default in the payment when due (at maturity, upon redemption or otherwise) of the principal of, or premium, if any, on, the Notes, (iii) failure by the
Company or any of its Restricted Subsidiaries to comply with Section 4.11 of the First Supplemental Indenture; (iv) failure by the Company or any of its Restricted Subsidiaries to comply with Section 4.02 of the First Supplemental
Indenture for 120 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class; (v) failure by the Company or any of its Restricted
Subsidiaries for 60 days after notice to the Company by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to comply with any of the other agreements or covenants in the
First Supplemental Indenture; (vi) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured or evidenced any Indebtedness for money borrowed by the Company or any of its Restricted
Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is created after the date of the First Supplemental Indenture, if that default:
(A) is caused by a failure to pay principal of on such Indebtedness at its stated final maturity (after giving effect to any applicable grace periods provided in such Indebtedness (a “Payment Default”); or (B) results in
the acceleration of such Indebtedness prior to its express maturity, and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or
the maturity of which has been so 

  

 A-5 

 
accelerated, aggregates $50.0 million or more; (vii) failure by the Company or any of its Significant Subsidiaries to pay final judgments with respect
to which no appeal may be or has been taken, entered by a court or courts of competent jurisdiction aggregating in excess of $50.0 million (net of any amounts that a reputable and creditworthy insurance company has acknowledged liability for in
writing), which judgments are not paid, discharged or stayed for a period of 60 days, and in the event such judgment is covered by insurance, an enforcement proceeding has been commenced by any creditor upon such judgment or decree which is not
promptly stayed; (viii) except as permitted by the First Supplemental Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Guarantor, or
any Person acting on behalf of any Guarantor, denies or disaffirms its obligations under its Note Guarantee; or (ix) certain events of bankruptcy or insolvency with respect to the Company or any of its Restricted Subsidiaries that is a
Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary. 
 If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately. Notwithstanding the
foregoing, in the case of an Event of Default arising from certain events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice. Holders may not enforce the First Supplemental
Indenture or the Notes except as provided in the First Supplemental Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default relating to the payment of principal or interest or premium, if any,) if it determines that
withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or waive any existing
Default or Event of Default and its consequences under the First Supplemental Indenture except a continuing Default or Event of Default in the payment of interest or premium, if any, on, or the principal of, the Notes. The Company is required to
deliver to the Trustee annually a statement regarding compliance with the First Supplemental Indenture, and the Company is required, upon becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such
Default or Event of Default. 
 TRUSTEE DEALINGS WITH
COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its
Affiliates, as if it were not the Trustee. 
 NO RECOURSE AGAINST
OTHERS. A director, officer, employee, incorporator or stockholder of the Company or any of the Guarantors, as such, will not have any liability for any obligations of the Company or the Guarantors under the Notes,
the Note Guarantees or the First Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are
part of the consideration for the issuance of the Notes.

 EXHIBIT B 
 [FORM OF SUPPLEMENTAL INDENTURE 
 TO BE DELIVERED BY SUBSEQUENT GUARANTORS] 
 SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of
                            , 200    , among
                             (the “Guaranteeing Subsidiary”), a subsidiary of Unisys
Corporation (or its permitted successor), a Delaware corporation (the “Company”), the Company, the other Guarantors (as defined in the First Supplemental Indenture referred to herein) and HSBC Bank USA, National Association, as
trustee under the First Supplemental Indenture referred to herein (the “Trustee”). 
 W I T N E S S E T H 
 WHEREAS, the Company has heretofore executed and delivered to the Trustee an Indenture, dated as of March 1, 2003 (the “Base
Indenture”), between the Company and the Trustee, as supplemented by the First Supplemental Indenture (the “First Supplemental Indenture”), dated as of December 11, 2007 (the Indenture, as supplemented by the First
Supplemental Indenture and any other supplemental indenture applicable to the Notes, the “Indenture”), providing for the issuance of 12.5% Senior Notes due 2016 (the “Notes”); 
 WHEREAS, the First Supplemental Indenture provides that under certain circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee
a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Company’s Obligations under the Notes and the First Supplemental Indenture on the terms and conditions set forth herein (the
“Note Guarantee”); and 
 WHEREAS, pursuant to Section 8.02 of the First Supplemental Indenture, the Trustee is
authorized to execute and deliver this Supplemental Indenture. 
 NOW, THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders as follows: 
 1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the
Indenture. 
 2. AGREEMENT TO GUARANTEE. The Guaranteeing Subsidiary hereby agrees to provide an
unconditional Guarantee on the terms and subject to the conditions set forth in the Note Guarantee and in the First Supplemental Indenture including but not limited to Article 9 thereof. 
 4. NO RECOURSE AGAINST OTHERS. No past, present or future director, officer, employee,
incorporator, stockholder or agent of the Guaranteeing Subsidiary, as such, shall have any liability for any obligations of the Company or any Guaranteeing Subsidiary under the Notes, any Note Guarantees, the First Supplemental Indenture or this
Supplemental Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the
consideration for issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy. 
 5. NEW YORK LAW TO GOVERN. THE INTERNAL LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE. 
  

 B-1 

 6. COUNTERPARTS. The parties may sign any number of copies of this Supplemental Indenture.
Each signed copy shall be an original, but all of them together represent the same agreement. 
 7. EFFECT OF
HEADINGS. The Section headings herein are for convenience only and shall not affect the construction hereof. 
 8.
THE TRUSTEE. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of
which recitals are made solely by the Guaranteeing Subsidiary and the Company. 
 IN WITNESS WHEREOF, the parties hereto have caused this
Supplemental Indenture to be duly executed and attested, all as of the date first above written.

                    , 20
