 -4-

 (c) In connection with the Registered Exchange Offer, the Issuers shall: 
 (i) mail to each Holder a copy of the Prospectus forming part of the Exchange Offer Registration Statement, together with an appropriate letter of transmittal and related documents; 

(ii) keep the Registered Exchange Offer open for not less than 20 Business Days and not more than 30 Business Days after
the date notice thereof is mailed to the Holders (or, in each case, longer if required by applicable law); 

(iii) use their best efforts to keep the Exchange Offer Registration Statement continuously effective under the Act,

(iv) utilize the services of a depositary for the Registered Exchange Offer with an address in the Borough of Manhattan in
New York City, which may be the Trustee or an Affiliate of the Trustee; 
 (v) permit Holders to withdraw
tendered Securities at any time prior to the close of business, New York time, on the last Business Day on which the Registered Exchange Offer is open; 
 (vi) prior to effectiveness of the Exchange Offer Registration Statement, provide a supplemental letter to the Commission (A) stating that the Issuers are conducting the Registered Exchange Offer in
reliance on the position of the Commission in Exxon Capital Holdings Corporation (pub. avail. May 13, 1988), and Morgan Stanley and Co., Inc. (pub. avail. June 5, 1991); and (B) including a representation that the
Issuers have not entered into any arrangement or understanding with any Person to distribute the New Securities to be received in the Registered Exchange Offer and that, to the best of the Issuers’ information and belief, each Holder
participating in the Registered Exchange Offer is acquiring the New Securities in the ordinary course of business and has no arrangement or understanding with any Person to participate in the distribution of the New Securities; and 

(vii) comply in all respects with all applicable laws. 

(d) As soon as practicable after the close of the Registered Exchange Offer, the Issuers shall: 

  
 -5-

 (i) accept for exchange all Securities tendered and not validly withdrawn
pursuant to the Registered Exchange Offer; 
 (ii) deliver to the Trustee for cancellation in accordance with the
Indenture and pursuant to Section 4(s) all Securities so accepted for exchange; and 
 (iii) cause the
Trustee promptly to authenticate in accordance with the Indenture a global certificate in a form eligible for deposit with the Depository Trust Company, representing New Securities exchanged for Securities and deliver to each Holder of Securities a
principal amount of New Securities equal to the principal amount of the Securities of such Holder so accepted for exchange. 

(e) Each Holder hereby acknowledges and agrees that any Broker-Dealer and any such Holder using the Registered Exchange Offer to
participate in a distribution of the New Securities (x) could not under Commission policy as in effect on the date of this Agreement rely on the position of the Commission in Morgan Stanley and Co., Inc. (pub. avail. June 5, 1991)
and Exxon Capital Holdings Corporation (pub. avail. May 13, 1988), as interpreted in the Commission’s letter to Shearman & Sterling dated July 2, 1993 and similar no-action letters; and (y) must comply with the
registration and prospectus delivery requirements of the Act in connection with any secondary resale transaction and must be covered by an effective registration statement containing the selling security holder information required by Item 507
or 508, as applicable, of Regulation S-K under the Act if the resales are of New Securities obtained by such Holder in exchange for Securities acquired by such Holder directly from any Issuer or one of its Affiliates. Accordingly, each Holder
participating in the Registered Exchange Offer shall be required to represent to the Issuers that, at the time of the consummation of the Registered Exchange Offer: 

(i) any New Securities received by such Holder will be acquired in the ordinary course of business; 

(ii) such Holder will have no arrangement or understanding with any Person to participate in the distribution of the
Securities or the New Securities within the meaning of the Act; and 
 (iii) such Holder is not an Affiliate of
the Issuers. 
 (f) If any Initial Purchaser determines that it is not eligible to participate in the Registered Exchange Offer
with respect to the exchange of Securities constituting any portion of an unsold allotment, at the request of such Initial Purchaser, the Issuers shall issue and deliver to such Initial Purchaser or the Person purchasing New Securities registered
under a Shelf Registration Statement as contemplated by Section 3 hereof from such Initial Purchaser, in exchange for such Securities, a like principal amount of New Securities. The Issuers shall use their best efforts to cause the CUSIP
Service Bureau to issue the same CUSIP number for such New Securities as for New Securities issued pursuant to the Registered Exchange Offer. 
 3. Shelf Registration. (a) If (i) due to any change in law or applicable interpretations thereof by the Commission’s staff, the Issuers determine upon advice of their outside

  
 -6-

 
counsel that they are not permitted to effect the Registered Exchange Offer as contemplated by Section 2 hereof; (ii) for any other reason the Registered Exchange Offer is not
consummated within 360 days of the date hereof; (iii) any Initial Purchaser so requests with respect to Securities that are not eligible to be exchanged for New Securities in the Registered Exchange Offer and that are held by it following
consummation of the Registered Exchange Offer; (iv) any Holder (other than an Initial Purchaser) is not eligible to participate in the Registered Exchange Offer; or (v) in the case of any Initial Purchaser that participates in the
Registered Exchange Offer or acquires New Securities pursuant to Section 2(f) hereof, such Initial Purchaser does not receive freely tradeable New Securities in exchange for Securities constituting any portion of an unsold allotment (it being
understood that (x) the requirement that an Initial Purchaser deliver a Prospectus containing the information required by Item 507 or 508 of Regulation S-K under the Act in connection with sales of New Securities acquired in exchange for
such Securities shall result in such New Securities being not “freely tradeable”; and (y) the requirement that an Exchanging Dealer deliver a Prospectus in connection with sales of New Securities acquired in the Registered Exchange
Offer in exchange for Securities acquired as a result of market-making activities or other trading activities shall not result in such New Securities being not “freely tradeable”), the Issuers shall effect a Shelf Registration Statement in
accordance with subsection (b) below. 
 (b) (i) The Issuers shall as promptly as practicable (but in no event more
than 210 days after so required or requested pursuant to this Section 3), file with the Commission and thereafter shall use their best efforts to cause to be declared effective under the Act a Shelf Registration Statement relating to the offer
and sale of the Securities or the New Securities, as applicable, by the Holders thereof from time to time in accordance with the methods of distribution elected by such Holders and set forth in such Shelf Registration Statement; provided,
however, that no Holder (other than an Initial Purchaser) shall be entitled to have the Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all of the provisions of this
Agreement applicable to such Holder; and provided, further, that with respect to New Securities received by an Initial Purchaser in exchange for Securities constituting any portion of an unsold allotment, the Issuers may, if permitted
by current interpretations by the Commission’s staff, file a post-effective amendment to the Exchange Offer Registration Statement containing the information required by Item 507 or 508 of Regulation S-K, as applicable, in satisfaction of
its obligations under this subsection with respect thereto, and any such Exchange Offer Registration Statement, as so amended, shall be referred to herein as, and governed by the provisions herein applicable to, a Shelf Registration Statement.

 (ii) The Issuers shall use their best efforts to keep the Shelf Registration Statement continuously effective, supplemented
and amended as required by the Act, in order to permit the Prospectus forming a part thereof to be usable by Holders for a period of two years from the date of issuance of the Securities or the New Securities, covered thereby, as applicable, or such
shorter period that will terminate when all the Securities or New Securities, as applicable, covered by the Shelf Registration Statement have been sold pursuant to the Shelf Registration Statement (in any such case, such period being called the
“Shelf Registration Period”). The Issuers shall be deemed not to have used their best efforts to keep the Shelf Registration Statement effective during the requisite period if they voluntarily take any action that would result in Holders
of Securities covered thereby not being able to offer and sell such Securities during that 

  
 -7-

 
period, unless (A) such action is required by applicable law; or (B) such action is taken by the Issuers in good faith and for valid business reasons (not including avoidance of the
Issuers’ obligations hereunder), including the acquisition or divestiture of assets, so long as the Issuers promptly thereafter comply with the requirements of Section 4(k) hereof, if applicable. 

(iii) The Issuers shall cause the Shelf Registration Statement and the related Prospectus and Free Writing Prospectuses, if any, and any
amendment or supplement thereto, as of the effective date of the Shelf Registration Statement or such amendment or supplement, (A) to comply in all material respects with the applicable requirements of the Act and the rules and regulations of
the Commission; (B) in the case of the Shelf Registration Statement, not to contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading
and (C) in the case of the Prospectus and Free Writing Prospectuses, not to include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

five Business Days prior to the filing thereof with the Commission, a copy of any Exchange Offer Registration Statement and any Shelf Registration Statement, and each amendment thereof and each amendment or supplement, if any, to the Prospectus

accompanied by an instruction to suspend the use of the Prospectus until the Issuers shall have remedied the basis for such suspension): 
 (i) when a Registration Statement and any amendment thereto has been filed with the Commission and when the Registration Statement or any post-effective amendment thereto has become effective;

(f) The Issuers shall, during the Shelf Registration Period, deliver to each Holder of Securities covered by any Shelf Registration
Statement, without charge, as many copies of the Prospectus and Free Writing Prospectuses (including each preliminary Prospectus) included in such Shelf Registration Statement and any amendment or supplement thereto as such Holder may reasonably
request. The Issuers consent to the use of the Prospectus and Free Writing Prospectuses or any amendment or supplement thereto by each of the selling Holders of Securities in connection with the offering and sale of the Securities covered by the

to take any action that would subject them to service of process in suits, other than those arising out of the Initial Placement, the Registered Exchange Offer or any offering pursuant to a Shelf Registration Statement, in any such jurisdiction
where they are not then so subject. 

  
 -10-

Issuers shall cooperate with the Holders of Securities to facilitate the timely preparation and delivery of certificates representing New Securities or Securities to be issued or sold pursuant to any Registration Statement free of any restrictive
legends and in such denominations and registered in such names as Holders may request. 
 (k) Upon the occurrence of any event
contemplated by subsections (c) (ii) or (v) above, the Issuers shall promptly prepare a post-effective amendment to the applicable Registration Statement or an amendment or supplement to the related Prospectus or file any other
required document so that, as thereafter delivered to initial purchasers of the securities included therein, the Prospectus will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were made, not misleading. In such circumstances, the period of effectiveness of the Exchange Offer Registration Statement provided for in Section 2 and the Shelf

Statement the Securities of any Holder that unreasonably fails to furnish such information within a reasonable time after receiving such request. 
 (p) In the case of any Shelf Registration Statement, the Issuers shall enter into such agreements and take all other appropriate actions (including if requested an underwriting agreement in customary
form) in order to expedite or facilitate the registration or the disposition of the Securities, and in connection therewith, if an underwriting agreement is entered into, cause the same to contain indemnification provisions and procedures no less
favorable than those set forth in Section 6 (or such other provisions and procedures acceptable to the Majority Holders and the Managing Underwriters, if any) with respect to all parties to be indemnified pursuant to Section 6.

 (q) In the case of any Shelf Registration Statement, the Issuers shall:

underwriter participating in any disposition pursuant to such Registration Statement, and any attorney, accountant or other agent retained by the Holders or any such underwriter all relevant financial and other records, pertinent corporate documents
and properties of the Issuers and their subsidiaries; 
 (ii) cause the Issuers’ officers, directors and
employees to supply all relevant information reasonably requested by the Holders or any such underwriter, attorney, accountant or agent in connection with any such Registration Statement as is customary for similar due diligence examinations;

attorney, accountant or agent, unless such disclosure is made in connection with a court proceeding or required by law, or such information becomes available to the public generally or through a third party without an accompanying obligation of
confidentiality; 
 (iii) make such representations and warranties to the Holders of Securities registered
thereunder and the underwriters, if any, in form, substance and scope as are customarily made by issuers to underwriters in primary underwritten offerings and covering matters including, but not limited to, those set forth in the Purchase Agreement;

and substance) shall be reasonably satisfactory to the Managing Underwriters, if any) addressed to each selling Holder and the underwriters, if any, covering such matters as are customarily covered in opinions requested in underwritten offerings and
such other matters as may be reasonably requested by such Holders and underwriters; 
 (v) obtain “cold
comfort” letters and updates thereof from the independent certified public accountants of the Issuers (and, if necessary, any other independent certified public accountants of any subsidiary of any Issuer or of any business acquired by the
Issuers for which financial statements and financial data are, or are required to be, included in the Registration Statement), addressed to each selling Holder of Securities registered thereunder and the underwriters, if any, in customary form and
covering matters of the type customarily covered in “cold comfort” letters in connection with primary underwritten offerings; and 
 (vi) deliver such documents and certificates as may be reasonably requested by the Majority Holders and the Managing Underwriters, if any, including those to evidence compliance with Section 4(k) and
with any customary conditions contained in the underwriting agreement or other agreement entered into by the Issuers. 

  
 -12-

 The actions set forth in clauses (iii), (iv), (v) and (vi) of this Section shall
be performed at (A) the effectiveness of such Registration Statement and each post-effective amendment thereto; and (B) each closing under any underwriting or similar agreement as and to the extent required thereunder. 

(r) In the case of any Exchange Offer Registration Statement, the Issuers shall: 

(i) make reasonably available for inspection by such Initial Purchaser, and any attorney, accountant or other agent
retained by such Initial Purchaser, all relevant financial and other records, pertinent corporate documents and properties of the Issuers and their subsidiaries; and 

(ii) cause the Issuers’ officers, directors and employees to supply all relevant information reasonably requested by
such Initial Purchaser or any such attorney, accountant or agent in connection with any such Registration Statement as is customary for similar due diligence examinations; provided, however, that any information that is designated in
writing by the Issuers, in good faith, as confidential at the time of delivery of such information shall be kept confidential by such Initial Purchaser or any such attorney, accountant or agent, unless such disclosure is made in connection with a
court proceeding or required by law, or such information becomes available to the public generally or through a third party without an accompanying obligation of confidentiality. 

(s) If a Registered Exchange Offer is to be consummated, upon delivery of the Securities by Holders to the Issuers (or to such other
Person as directed by the Issuers) in exchange for the New Securities, the Issuers shall mark, or caused to be marked, on the Securities so exchanged that such Securities are being canceled in exchange for the New Securities. In no event shall the
Securities be marked as paid or otherwise satisfied. 
 (t) The Issuers will use their best efforts (i) if the Securities
have been rated prior to the initial sale of such Securities, to confirm such ratings will apply to the Securities or the New Securities, as the case may be, covered by a Registration Statement; or (ii) if the Securities were not previously
rated, to cause the Securities covered by a Registration Statement to be rated with at least one nationally recognized statistical rating agency, if so requested by Majority Holders with respect to the related Registration Statement or by any
Managing Underwriters. 
 (u) In the event that any Broker-Dealer shall underwrite any Securities or participate as a member of
an underwriting syndicate or selling group or “assist in the distribution” (within the meaning of the Conduct Rules of the National Association of Securities Dealers, Inc. (the “Conduct Rules”)) thereof, whether as a Holder of
such Securities or as an underwriter, a placement or sales agent or a broker or dealer in respect thereof, or otherwise, assist such Broker-Dealer in complying with the requirements of such Conduct Rules, including, without limitation, by:

 (i) if such Conduct Rules or the rules of the Financial Industry Regulatory Authority, Inc. shall so require,
engaging a “qualified independent underwriter” (as de-

 (v) The Issuers shall use their best efforts to take all other steps necessary to effect the registration of the Securities or the New Securities, as the case may be, covered by a Registration Statement.

 5. Additional Interest. In the event that (i) neither the Exchange Offer Registration
Statement nor the Shelf Registration Statement has been filed with the Commission on or prior to the 210th day following the date of the original issuance of the Securities, (ii) the Exchange Offer Registration Statement has not been declared effective on or prior to the 330th day following the date of the original issuance of the Securities,
(iii) the Registered Exchange Offer has not been consummated on or prior to the 360th day following the date of the original issuance of the Securities, (iv) notwithstanding the fact that the Issuers have or may consummate a Registered Exchange Offer, the Issuers are required to file
a Shelf Registration Statement and such Shelf Registration Statement is not filed on or prior to the 210th day following the date when the Issuers first become obligated to file such Shelf Registration Statement, (v) notwithstanding the fact that the Issuers have or may consummate a Registered Exchange
Offer, the Issuers are required to file a Shelf Registration Statement and such Shelf Registration Statement is not declared effective on or prior to the 330th day following the date when the Issuers first become obligated to file such Shelf Registration Statement, or
(vi) after the Exchange Offer Registration Statement or the Shelf Registration Statement has been declared effective, such Registration Statement thereafter ceases to be effective or usable in connection with exchanges or resales, as the case
may be, of the Securities at any time that the Issuers are obligated to maintain the effectiveness thereof pursuant to this Agreement (each such event referred to in clauses (i) through (vi) above being referred to herein as a
“Registration Default”), interest (“Additional Interest”) shall accrue (in addition to stated interest on the Securities) from and including the date on which the first such Registration Default shall occur to but excluding the
date on which all Registration Defaults have been cured, at a rate per annum equal to 0.25% of the principal amount of the Securities; provided, however, that such rate per annum shall increase by an additional 0.25% per annum from and
including the 91st day after the first such Registration
Default (and each successive 91st day thereafter) unless
and until all Registration Defaults have been cured; provided further, however, that in no event shall the Additional Interest accrue at a rate in excess of 1.00% per annum. The Additional Interest will be payable in cash semiannually in
arrears each interest payment date.

 6. Registration Expenses. The Issuers shall bear all expenses incurred in connection
with the performance of their obligations under Sections 2, 3 and 4 hereof and, in the event of any Shelf Registration Statement, will reimburse the Holders for the reasonable fees and disbursements of one firm or counsel designated by the Majority
Holders to act as counsel for the Holders in connection therewith, and, in the case of any Exchange Offer Registration Statement, will reimburse the Initial Purchasers for the reasonable fees and disbursements of counsel acting in connection
therewith. 
 7. Indemnification and Contribution. (a) The Issuers jointly and severally agree to indemnify and hold
harmless each Holder of Securities or New Securities, as the case may be, covered by any Registration Statement (including each Initial Purchaser and each Affiliate thereof and, with respect to any Prospectus delivery as contemplated in
Section 4(h) hereof, each Exchanging Dealer), the directors, officers, employees and agents of each such Holder and each Person who controls any such Holder within the meaning of either the Act or the Exchange Act against any and all losses,
claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in
any preliminary Prospectus or the Prospectus or any Free Writing Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein (in the case of any preliminary Prospectus or the Prospectus, in light of the circumstances under which they were made) not misleading, and agree to reimburse each such indemnified party, as
incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Issuers will not be liable in any case
to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written
information furnished to the Issuers by or on behalf of any such Holder specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Issuers may otherwise have. 

The Issuers also jointly and severally agree to indemnify or contribute as provided in Section 6(d) to Losses of each underwriter of
Securities or New Securities, as the case may be, registered under a Shelf Registration Statement, their directors, officers, employees or agents and each Person who controls such underwriter on substantially the same basis as that of the
indemnification of the Initial Purchasers and the selling Holders provided in this Section 6(a) and shall, if requested by any Holder, enter into an underwriting agreement reflecting such agreement, as provided in Section 4(p) hereof.

 (b) Each Holder of securities covered by a Registration Statement (including each Initial Purchaser and each Affiliate
thereof and, with respect to any Prospectus delivery as contemplated in Section 4(h) hereof, each Exchanging Dealer) severally agrees to indemnify and hold harmless the Issuers, each of their directors, each of their officers who signs such
Registration Statement and each Person who controls the Issuers within the meaning of either the Act or 

  
 -15-

 
the Exchange Act, to the same extent as the foregoing indemnity from the Issuers to each such Holder, but only with reference to written information relating to such Holder furnished to the
Issuers by or on behalf of such Holder specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any such Holder may otherwise have. 

(c) Promptly after receipt by an indemnified party under this Section 6 of notice of the commencement of any action, such
indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party
(i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and
defenses; and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be
entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not
thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party.
Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party
shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with an actual or potential conflict of
interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses
available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to
represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.
An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of
which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each
indemnified party from all liability arising out of such claim, action, suit or proceeding. 
 (d) In the event that the
indemnity provided in paragraph (a) or (b) of this Section is unavailable to or insufficient to hold harmless an indemnified party for any reason, then each applicable indemnifying party shall have a joint and several obligation to
contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which such indemnified party may be
subject in such proportion as is appropriate to reflect the relative benefits received by such indemnifying party, on the one hand, and such indemnified party, on 

  
 -16-

 
the other hand, from the Initial Placement and the Registration Statement which resulted in such Losses; provided, however, that in no case shall any Initial Purchaser or any
subsequent Holder of any Security or New Security be responsible, in the aggregate, for any amount in excess of the purchase discount or commission applicable to such Security, or in the case of a New Security, applicable to the Security that was
exchangeable into such New Security, as set forth on the cover page of the Final Memorandum, nor shall any underwriter be responsible for any amount in excess of the underwriting discount or commission applicable to the securities purchased by such
underwriter under the Registration Statement which resulted in such Losses. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the indemnifying party and the indemnified party shall contribute in such
proportion as is appropriate to reflect not only such relative benefits but also the relative fault of such indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the statements or omissions which
resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Issuers shall be deemed to be equal to the sum of (x) the total net proceeds from the Initial Placement (before deducting expenses) as set
forth on the cover page of the Final Memorandum and (y) the total amount of additional interest which the Issuers were not required to pay as a result of registering the securities covered by the Registration Statement which resulted in such
Losses. Benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions as set forth on the cover page of the Final Memorandum, and benefits received by any other Holders shall be deemed to be
equal to the value of receiving Securities or New Securities, as applicable, registered under the Act. Benefits received by any underwriter shall be deemed to be equal to the total underwriting discounts and commissions, as set forth on the cover
page of the Prospectus forming a part of the Registration Statement which resulted in such Losses. Relative fault shall be determined by reference to, among other things, whether any alleged untrue statement or omission relates to information
provided by the indemnifying party, on the one hand, or by the indemnified party, on the other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or
omission. The parties agree that it would not be just and equitable if contribution were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or any other method of allocation which does
not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent misrepresentation. For purposes of this Section, each Person who controls a Holder within the meaning of either the Act or the Exchange Act and each director, officer, employee and
agent of such Holder shall have the same rights to contribution as such Holder, and each Person who controls any Issuer within the meaning of either the Act or the Exchange Act, each officer of any Issuer who shall have signed the Registration
Statement and each director of any Issuer shall have the same rights to contribution as the Issuers, subject in each case to the applicable terms and conditions of this paragraph (d). 

(e) The provisions of this Section will remain in full force and effect, regardless of any investigation made by or on behalf of any
Holder or the Issuers or any of the officers, directors or controlling Persons referred to in this Section hereof, and will survive the sale by a Holder of securities covered by a Registration Statement. 

  
 -17-

 8. Underwritten Registrations. (a) If any of the Securities or New Securities,
as the case may be, covered by any Shelf Registration Statement are to be sold in an underwritten offering, the Managing Underwriters shall be selected by the Majority Holders. 

(b) No Person may participate in any underwritten offering pursuant to any Shelf Registration Statement, unless such Person
(i) agrees to sell such Person’s Securities or New Securities, as the case may be, on the basis reasonably provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements; and
(ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements. 

9. No Inconsistent Agreements. No Issuer has, as of the date hereof, entered into, nor shall it, on or after the date hereof,
enter into, any agreement with respect to its securities that is inconsistent with the rights granted to the Holders herein or otherwise conflicts with the provisions hereof. 
 10. Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, qualified, modified or supplemented, and waivers or consents to
departures from the provisions hereof may not be given, unless the Issuers have obtained the written consent of the Majority Holders (or, after the consummation of any Registered Exchange Offer in accordance with Section 2 hereof, of the
Holders of a majority aggregate principal amount New Securities affected thereby); provided that, with respect to any matter that directly or indirectly affects the rights of any Initial Purchaser hereunder, the Issuers shall obtain the
written consent of each such Initial Purchaser against which such amendment, qualification, supplement, waiver or consent is to be effective. Notwithstanding the foregoing (except the foregoing proviso), a waiver or consent to departure from the
provisions hereof with respect to a matter that relates exclusively to the rights of Holders whose Securities or New Securities, as the case may be, are being sold pursuant to a Registration Statement and that does not directly or indirectly affect
the rights of other Holders may be given by the Majority Holders, determined on the basis of Securities or New Securities, as the case may be, being sold rather than registered under such Registration Statement. 

11. Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery,
first-class mail, telex, telecopier or air courier guaranteeing overnight delivery: 
 (a) if to a Holder, at the
most current address given by such Holder to the Issuers in accordance with the provisions of this Section, which address initially is, with respect to each Holder, the address of such Holder maintained by the Registrar under the Indenture, with a
copy in like manner to J.P. Morgan Securities Inc.; 
 (b) if to you, initially at the address set forth in the
Purchase Agreement; and 
 (c) if to the Issuers, initially at their address set forth in the Purchase Agreement.

  
 -18-

 All such notices and communications shall be deemed to have been duly given when received.

 The Initial Purchasers or the Issuers by notice to the other parties may designate additional or different addresses for
subsequent notices or communications. 
 12. Successors. This Agreement shall inure to the benefit of and be binding upon
the successors and assigns of each of the parties, including, without the need for an express assignment or any consent by the Issuers thereto, subsequent Holders of Securities and the New Securities. The Issuers hereby agree to extend the benefits
of this Agreement to any Holder of Securities and the New Securities, and any such Holder may specifically enforce the provisions of this Agreement as if an original party hereto. 

13. Counterparts. This Agreement may be in signed counterparts, each of which shall constitute an original and all of which
together shall constitute one and the same agreement. 
 14. Headings. The headings used herein are for convenience only
and shall not affect the construction hereof. 
 15. Applicable Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York applicable to contracts made and to be performed in the State of New York. 

16. Severability. In the event that any one or more of the provisions contained herein, or the application thereof in any
circumstances, is held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and of the remaining provisions hereof shall not be in any way impaired or
affected thereby, it being intended that all of the rights and privileges of the parties shall be enforceable to the fullest extent permitted by law. 
 17. Securities Held by the Issuers, etc. Whenever the consent or approval of Holders of a specified percentage of principal amount of Securities or New Securities is required hereunder, Securities
or New Securities, as applicable, held by any Issuer or its Affiliates (other than subsequent Holders of Securities or New Securities if such subsequent Holders are deemed to be Affiliates solely by reason of their holdings of such Securities or New
Securities) shall not be counted in determining whether such consent or approval was given by the Holders of such required percentage.

 ANNEX A 
 Each Broker-Dealer that receives New Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Securities.
The Letter of Transmittal states that by so acknowledging and by delivering a prospectus, a Broker-Dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Act. This Prospectus, as it may be amended or
supplemented from time to time, may be used by a Broker-Dealer in connection with resales of New Securities received in exchange for Securities where such Securities were acquired by such Broker-Dealer as a result of market-making activities or
other trading activities. The Issuers have agreed that, starting on the Expiration Date (as defined herein) and ending on the close of business one year after the Expiration Date, they will make this Prospectus available to any Broker-Dealer for use
in connection with any such resale. See “Plan of Distribution”. 

 ANNEX B 
 Each Broker-Dealer that receives New Securities for its own account in exchange for Securities, where such Securities were acquired by such Broker-Dealer as a result of market-making activities or other
trading activities, must acknowledge that it will deliver a prospectus in connection with any resale of such New Securities. See “Plan of Distribution”. 

 ANNEX C 
 PLAN OF DISTRIBUTION 
 Each Broker-Dealer that receives New
Securities for its own account pursuant to the Exchange Offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Securities. This Prospectus, as it may be amended or supplemented from time to time, may be
used by a Broker-Dealer in connection with resales of New Securities received in exchange for Securities where such Securities were acquired as a result of market-making activities or other trading activities. The Issuers have agreed that, starting
on the Expiration Date and ending on the close of business one year after the Expiration Date, they will make this Prospectus, as amended or supplemented, available to any Broker-Dealer for use in connection with any such resale. In addition, until
                    , 200    , all dealers effecting transactions in the New Securities may be required to deliver a prospectus
or make one available. 
 The Issuers will not receive any proceeds from any sale of New Securities by Brokers-Dealers. New
Securities received by Broker-Dealers for their own account pursuant to the Exchange Offer may be sold from time to time in one or more transactions in the over-the-counter market, in negotiated transactions, through the writing of options on the
New Securities or a combination of such methods of resale, at market prices prevailing at the time of resale, at prices related to such prevailing market prices or negotiated prices. Any such resale may be made directly to purchasers or to or
through brokers or dealers who may receive compensation in the form of commissions or concessions from any such Broker-Dealer and/or the purchasers of any such New Securities. Any Broker-Dealer that resells New Securities that were received by it
for its own account pursuant to the Exchange Offer and any broker or dealer that participates in a distribution of such New Securities may be deemed to be an “underwriter” within the meaning of the Act and any profit of any such resale of
New Securities and any commissions or concessions received by any such Persons may be deemed to be underwriting compensation under the Act. The Letter of Transmittal states that by acknowledging that it will deliver and by delivering a prospectus, a
Broker-Dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Act. 
 For a period
of one year after the Expiration Date, the Issuers will promptly send additional copies of this Prospectus and any amendment or supplement to this Prospectus to any Broker-Dealer that requests such documents in the Letter of Transmittal. The Issuers
have agreed to pay all expenses incident to the Exchange Offer (including the reasonable expenses of one counsel for the holder of the Securities) other than commissions or concessions of any brokers or dealers and will indemnify the holders of the
Securities (including any Broker-Dealers) against certain liabilities, including liabilities under the Act.

 Exhibit 10.1 
 IPC THE HOSPITALIST COMPANY, INC. 
 2007 EQUITY PARTICIPATION PLAN

 PERFORMANCE UNIT AGREEMENT 
 PERFORMANCE UNIT AGREEMENT (the “Agreement”), dated as of
[                    ] (the “Grant Date”) by and between IPC The Hospitalist Company, Inc. (the “Company”), and
[                ] (the “Grantee”). 
 In accordance with Section 11 of the IPC The Hospitalist Company, Inc. 2007 Equity Participation Plan (the “Plan”) and subject to the terms of the Plan and this Agreement, the
Company hereby grants to the Grantee a performance unit award (the “Award”) with respect to [            ] shares of the Company’s Common Stock, par value $0.001 per
share (the “Stock”) on the terms and conditions as set forth herein. Capitalized terms used but not otherwise defined herein shall have the meaning set forth in the Plan 

To evidence the Award and to set forth its terms, the Company and the Grantee agree as follows: 

1. Award Subject to Acceptance of Agreement. The Award shall be null and void unless the Grantee accepts this Agreement by
executing it in the space provided below and returning such original execution copy to the Company. 
 2. Rights as a
Stockholder. 
 (a) The Grantee shall not be entitled to any privileges of ownership with respect to the shares of Stock
subject to the Award unless and until such shares become vested pursuant to Section 3 hereof and the Grantee becomes a stockholder of record with respect to such shares. 

(b) As of each date on which the Company pays a cash dividend to record owners of shares of Stock (a “Dividend Date”),
the number of shares subject to the Award shall increase by (i) the product of the total number of shares subject to the Award immediately prior to such Dividend Date multiplied by the dollar amount of the cash dividend paid per share of Stock
by the Company on such Dividend Date, divided by (ii) the Fair Market Value of a share of Stock on such Dividend Date. Any such additional shares shall be subject to the same vesting conditions and payment terms as the shares to which they
relate. 
 3. Performance Goals and Vesting. 
 (a) General. The Award shall vest pursuant to the terms of this Agreement and the Plan based on the achievement of the following performance goal, provided that that the Grantee remains in
continuous employment with the Company through the applicable Vesting Date: 
 [PERFORMANCE GOALS] 

Subject to the achievement of the performance goal set forth above, 50% of the Award shall vest on the second anniversary of the Grant Date and the
remaining 50% of the Award shall vest on the third anniversary of the Grant Date (each date, a “Vesting Date”). Attainment of the performance goals shall be determined and certified by the Committee in writing within 60 days
following the last day of the Performance Period. 
 (b) Termination of Service. Notwithstanding the foregoing
provisions and except as otherwise provided for in Section 3(c) of this Agreement, if the Grantee incurs a Termination of Service for any reason before the applicable Vesting Date, any portion of the Award which is not vested at the time the
Grantee incurs a Termination of Service shall be immediately forfeited. 
 ( c) Change in Control. Notwithstanding anything in
this Section 3 to the contrary, in the event that the Grantee incurs a Termination of Service within ninety (90) days immediately preceding or eighteen (18) months 

  
 1 

 
immediately following the occurrence of a Change in Control for any reason other than death, Disability, termination by the 
 Company for Cause or voluntary termination by the Grantee for other than Good Reason, the Company shall issue or transfer to the Grantee the number of shares of Stock subject to the Award as of the date
of such Termination of Service or Change in Control (whichever is later), within seventy-five (75) days following the Grantee’s Termination of Service or Change in Control (whichever is later). For purposes of this Agreement, the terms
“Cause,” “Disability,” and “Good Reason” shall have the meanings assigned to such terms in the Executive Change in Control Plan applicable to the Grantee on the Grant Date. 

4. Settlement of Award. Subject to Section 10 and the Committee’s certification of the
attainment of the performance goal, as soon as practicable after the applicable Vesting Date, the Company shall issue or transfer to the Grantee the number of shares of Stock subject to the Award that are vested (provided that such shares of Stock
shall be issued no later than the March 15th
immediately following the applicable Vesting Date). The Company may effect such issuance or transfer either by the delivery of one or more stock certificates to the Grantee or by making an appropriate entry on the books of the Company or the
transfer agent of the Company. 
 5. Transfer Restrictions and Investment Representation. 

(a) Nontransferability of Award. The Award may not be transferred by the Grantee other than by will or the laws of descent and
distribution or pursuant to the designation of one or more beneficiaries on the form prescribed by the Company. Except to the extent permitted by the foregoing sentence, the Award may not be sold, transferred, assigned, pledged, hypothecated,
encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of the Award,
the Award and all rights hereunder shall immediately become null and void. 
 (b) Investment Representation. The Grantee
hereby represents and covenants that (a) any share of Stock acquired upon the vesting of the Award will be acquired for investment and not with a view to the distribution thereof within the meaning of the Securities Act of 1933, as amended (the
“Securities Act”), unless such acquisition has been registered under the Securities Act and any applicable state securities laws; (b) any subsequent sale of any such shares shall be made either pursuant to an effective
registration statement under the Securities Act and any applicable state securities laws, or pursuant to an exemption from registration under the Securities Act and such state securities laws; and (c) if requested by the Company, the Grantee
shall submit a written statement, in form satisfactory to the Company, to the effect that such representation (x) is true and correct as of the date of vesting of any shares of Stock hereunder or (y) is true and correct as of the date of
any sale of any such share, as applicable. As a further condition precedent to the delivery to the Grantee of any shares of Stock subject to the Award, the Grantee shall comply with all regulations and requirements of any regulatory authority having
control of or supervision over the issuance or delivery of the shares and, in connection therewith, shall execute any documents which the Board shall in its sole discretion deem necessary or advisable. 

6. Effect of Amendment of Plan. No discontinuation, modification, or amendment of the Plan may, without the written consent of the
Grantee, adversely affect the rights of the Grantee under the Award, except as otherwise provided under the Plan. This Agreement may be amended as provided under the Plan, but except as provided thereunder shall not adversely affect Grantee’s
rights hereunder without Grantee’s consent. 
 7. No Limitation on Rights of the Company. The grant of the Award
shall not in any way affect the right or power of the Company to make adjustments, reclassifications, or changes in its capital or business structure or to merge, consolidate, dissolve, liquidate, sell, or transfer all or any part of its business or
assets. 
 8. Compliance with Applicable Law. The Award is subject to the condition that if the listing, registration or
qualification of the shares of Stock subject to the Award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in
connection with, the vesting or delivery of shares hereunder, the shares of Stock subject to the Award shall not vest or be delivered, in whole or in part, unless such listing, registration, qualification, consent, approval or other action shall
have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent, approval or other action. 

9. Agreement Not a Contract of Employment or Other Relationship. This Agreement is not a contract of employment, and the terms of
employment of the Grantee or other relationship of the Grantee with the Company or any of its subsidiaries or affiliates shall not be affected in any way by this Agreement except as specifically provided herein. The execution of this Agreement shall
not be construed as conferring any legal rights upon the Grantee for a continuation of employment or other 

  
 2 

 
relationship with the Company or any of its subsidiaries or affiliates, nor shall it interfere with the right of the Company or any of its subsidiaries or affiliates to discharge the Grantee and
to treat him or her without regard to the effect which such treatment might have upon him or her as a Grantee.
