Global Note Legend and the Private Placement Legend and deposited with or on behalf of, and registered in the name of, the Depositary or its nominee that will be issued in a denomination equal to the outstanding principal amount of the Notes
initially sold in reliance on Rule 144A. 
 “Acquired Debt” means, with respect to any specified Person: 

(1) Indebtedness of any other Person existing at the time such other Person is merged with or into or became a Subsidiary of
such specified Person, whether or not such Indebtedness is incurred in connection with, or in contemplation of, such other Person merging with or into, or becoming a Restricted Subsidiary of, such specified Person, but excluding Indebtedness which
is extinguished, retired or repaid in connection with such Person merging with or becoming a Subsidiary of such specific Person; and 

(2) Indebtedness secured by a Lien encumbering any asset acquired by such specified Person. 

“Additional Notes” means additional Notes (other than the Initial Notes) issued under this Indenture in accordance with
Sections 2.02 and 4.09 hereof, as part of the same series as the Initial Notes.  
 “Affiliate” of any specified
Person means any other Person directly or indirectly controlling or controlled by or under direct or indirect common control with such specified Person. For purposes of this definition, “control,” as used with respect to any Person, means

(such redemption price being set forth in the table appearing in Section 3.07 hereof) plus (ii) all required interest payments due on the Note through August 1, 2019 (excluding accrued but unpaid interest to the Redemption Date),
computed using a discount rate equal to the Treasury Rate as of such Redemption Date plus 50 basis points; over (b) the principal amount of the Note, if greater.

other disposition of all or substantially all of the assets of Holly Energy Partners and its Restricted Subsidiaries taken as a whole will be governed by Section 4.15 hereof and/or Section 5.01 hereof and not by Section 4.10 hereof;
and 
 (2) the issuance of Equity Interests in any of Holly Energy Partners’ Restricted Subsidiaries or the sale of
Equity Interests in any of its Restricted Subsidiaries. 
 Notwithstanding the preceding, none of the following items will be deemed to be

which the Person whose Equity Interests have been so disposed of continues to be a Restricted Subsidiary, provided that the Fair Market Value of the properties or assets traded or exchanged by Holly Energy Partners or such Restricted
Subsidiary (together with any cash or Cash Equivalent together with the liabilities assumed) is reasonably equivalent to the Fair Market Value of the properties or assets (together with any cash or Cash Equivalent together with liabilities assumed)
to be received by Holly Energy Partners or such Restricted Subsidiary; and provided further that any cash received must be applied in accordance with Section 4.10 hereof;

 “Attributable Debt” in respect of a
sale-and-leaseback transaction means, at the time of determination, the present value of the obligation of the lessee for net rental payments during the remaining term of the lease included in such sale-and-leaseback transaction including any period

to be paid with respect to such period by the lessee thereunder, excluding any amounts required to be paid by such lessee on account of maintenance and repairs, insurance, taxes, assessments, water rates or similar charges. In the case of any lease
that is terminable by the lessee upon payment of penalty, such net rental payment shall also include the amount of such penalty, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may
be so terminated. For purposes of this definition, present value shall be calculated using a discount rate equal to the rate of interest implicit in the subject transaction, determined in accordance with GAAP; provided, however, that
if such sale-and-leaseback transaction results in a Capital Lease Obligation, the amount of Indebtedness represented thereby will be determined in accordance with the definition of “Capital Lease Obligation.”

 “Bankruptcy Law” means Title 11, U.S. Code or any similar federal or state law for the relief of debtors.

 “Beneficial Owner” has the meaning assigned to such term in Rule 13d-3 and Rule 13d-5 under the Exchange Act,

such “person” has the right to acquire by conversion or exercise of other securities, whether such right is currently exercisable or is exercisable only after the passage of time. The terms “Beneficially Owns” and
“Beneficially Owned” have a corresponding meaning. 
 “Board of Directors” means: 

(1) with respect to a corporation, the board of directors of the corporation or any committee thereof duly authorized to act on
behalf of such board; 
 (2) with respect to a partnership, the Board of Directors or Board of Managers of the general
partner of the partnership, or in the case of Holly Energy Partners, the Board of Directors of Holly Logistic Services, L.L.C., the general partner of HEP Logistics Holdings, L.P.; 

  
 3 

 (3) with respect to a limited liability company, the managing member or members
or any controlling committee of managing members thereof; and 
 (4) with respect to any other Person, the board or committee
of such Person serving a similar function. 
 “Business Day” means any day other than a Legal Holiday. 

“Capital Lease Obligation” means an obligation that is required to be classified and accounted for as a capital lease for
financial reporting purposes in accordance with GAAP, and the amount of Indebtedness represented by such obligation shall be, at the time any determination thereof is to be made, the amount of the liability in respect of a capital lease that would
at such time be required to be capitalized on a balance sheet in accordance with GAAP, and the Stated Maturity thereof shall be the date of the last payment of rent or any other amount due under such lease prior to the first date upon which such
lease may be prepaid by the lessee without payment of a penalty. 
 “Capital Stock” means: 

(1) in the case of a corporation, corporate stock; 

(2) in the case of an association or business entity, any and all shares, interests, participations, rights or other
equivalents (however designated) of corporate stock;

partnership interests (whether general or limited) or membership interests; and 
 (4) any other interest or participation
that confers on a Person the right to receive a share of the profits and losses of, or distributions of assets of, the issuing Person, but excluding from all of the foregoing any debt securities convertible into Capital Stock, whether or not such
debt securities include any right of participation with Capital Stock. 
 “Cash Equivalents” means: 

(1) United States dollars; 

(2) securities issued or fully guaranteed or insured by the United States government or any agency thereof having maturities of
not more than twenty-four (24) months from the date of acquisition thereof;

with stable outlook) by S&P and A3 (or then equivalent grade, in each case with stable outlook) by Moody’s at the time of acquisition and such financial institution otherwise meets the requirements of subsections (a) and (c) of

the date of acquisition; 
 (7) repurchase agreements relating to any of the investments listed in clauses (1) through

(8) asset-backed securities having as the underlying asset securities issued or guaranteed by the Federal Home Loan Mortgage

 (2) the adoption of a plan relating to the
liquidation or dissolution of Holly Energy Partners or the removal of the General Partner by the limited partners of Holly Energy Partners; or

that any “person” (as defined above), other than a Qualified Owner, becomes the Beneficial Owner, directly or indirectly, of more than 50% of the Voting Stock of the General Partner or of Holly Logistic Services L.L.C., measured by voting
power rather than number of shares, which occurrence is followed by a Rating Decline.

partnership to a corporation, limited liability company or other form of entity or an exchange of all of the outstanding limited partnership interests for capital stock in a corporation, for member interests in a limited liability company or for
Equity Interests in such other form of entity shall not constitute a Change of Control, so long as following such conversion or exchange the “persons” (as defined above) who Beneficially Owned the Capital Stock of Holly Energy Partners
immediately prior to such transactions continue to Beneficially Own in the aggregate more than 50% of the Voting Stock of such entity, or continue to Beneficially Own sufficient Equity Interests in such entity to elect a majority of its directors,
managers, trustees or other persons serving in a similar capacity for such entity and (b) a “person” or “group” shall not be deemed to Beneficially Own securities subject to a stock or asset purchase agreement, merger

and integral multiples of $1,000 in excess thereof. 
 The terms and provisions contained in the Notes will
constitute, and are hereby expressly made, a part of this Indenture and the Issuers, the Guarantor and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to
the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling. 

(b) Global Notes. Notes issued in global form will be substantially in the form of Exhibit A hereto (including
the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form will be substantially in the form of Exhibit A hereto (but without the Global Note Legend

more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Issuers may change any Paying Agent or Registrar
without notice to any Holder. The Issuers will notify the Trustee in writing of the name and address of any Agent not a party to this Indenture. If the Issuers fail to appoint or maintain another entity as Registrar or Paying Agent, the Trustee
shall act as such. Holly Energy Partners, Finance Corp. or any of Holly Energy Partners’ other Subsidiaries may act as Paying Agent or Registrar. 

The Issuers initially appoint The Depository Trust Company (“DTC”) to act as Depositary with respect to the Global
Notes. 
 The Issuers initially appoint the Trustee to act as the Registrar and Paying Agent at its Corporate Trust Office and to act
as Custodian with respect to the Global Notes.

 Section 2.04 Paying Agent to Hold Money in Trust. 

The Issuers will require each Paying Agent other than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit
of Holders or the Trustee all money held by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and will notify the Trustee of any default by the Issuers in making any such payment. While any such default
continues, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. The Issuers at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other
than Holly Energy Partners or a Subsidiary) will have no further liability for the money. If Holly Energy Partners or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money
held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to Holly Energy Partners, the Trustee will serve as Paying Agent for the Notes. 

Section 2.05 Holder Lists. 
 The
Trustee will preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of all Holders. If the Trustee is not the Registrar, the Issuers will furnish to the Trustee at least seven
Business Days before each interest payment date and at such other times as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes. 

Section 2.06 Transfer and Exchange. 

(a) Transfer and Exchange of Global Notes. A Global Note may not be transferred except as a whole by the
Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All
Global Notes will be exchanged by the Issuers for Definitive Notes if: 
 (1) the Issuers deliver to the Trustee
notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Issuers within
90 days; 
 (2) the Issuers, at their option but subject to the Depositary’s rules, determine that the Global Notes (in

(3) there has occurred and is continuing a Default or Event of Default with respect to the Notes, and the Depositary notifies
the Trustee of its decision to exchange the Global Notes for Definitive Notes. 
 Upon the occurrence of any of the preceding events in (1),
(2) or (3) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note
authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global
Note. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a); however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b) or (c) hereof.

retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the

(2) No service charge will be made to a Holder of a beneficial interest in a Global Note or to a Holder of a Definitive Note
for any registration of transfer or exchange, but the Issuers may require payment of a sum sufficient to cover any transfer or exchange tax or similar governmental charge payable in connection therewith (other than any such transfer or exchange
taxes or similar governmental charge payable upon exchange or transfer pursuant to Sections 2.10, 3.06, 3.09, 4.10, 4.15 and 9.04 hereof). 

(3) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive

the Issuers, the Trustee, any Agent and any authenticating agent from any loss that any of them may suffer if a Note is replaced. The Issuers may charge for their expenses in replacing a Note. 

Every replacement Note is an additional obligation of each of the Issuers and will be entitled to all of the benefits of this Indenture

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered
to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09
hereof, a Note does not cease to be outstanding because the Issuers or an Affiliate of the Issuers holds the Note; however, Notes held by Holly Energy Partners or a Subsidiary of Holly Energy Partners shall not be deemed to be outstanding for
purposes of Section 3.07(a) hereof. 
 If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser. 
 If the
principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 

If the Paying Agent (other than Holly Energy Partners, a Subsidiary or an Affiliate of any thereof) holds, by 11:00 a.m., Eastern Time, on a
Redemption Date or other maturity date, money sufficient to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to accrue interest.

 Section 2.09 Treasury Notes. 

In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by
the Issuers or any Guarantor, or by any Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Issuers or any Guarantor, will be considered as though not outstanding, except that for the
purposes of determining whether the Trustee will be protected in relying on any such direction, waiver or consent, only Notes that the Trustee knows are so owned will be so disregarded. 

Section 2.10 Temporary Notes. 
 Until
certificates representing Notes are ready for delivery, the Issuers may prepare and the Trustee, upon receipt of an Authentication Order, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes but
may have variations that the Issuers consider appropriate for temporary Notes and as may be reasonably acceptable to the Trustee. Without unreasonable delay, the Issuers will prepare and the Trustee will authenticate definitive Notes in exchange for
temporary Notes. 
 Holders of temporary Notes will be entitled to all of the benefits of this Indenture. 

Section 2.11 Cancellation. 
 The
Issuers at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee and no one else will
cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and will destroy canceled Notes (subject to the record retention requirement of the Exchange Act). Certification of the destruction of all
canceled Notes will be delivered to the Issuers. The Issuers may not issue new Notes to replace Notes that they have paid or that have been delivered to the Trustee for cancellation. 

Section 2.12 Defaulted Interest. 

If the Issuers default in a payment of interest on the Notes, they will pay the defaulted interest in any lawful manner plus, to the
extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01 hereof. The Issuers will notify the Trustee in
writing of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Issuers will fix or cause to be fixed each such special record date and payment date; provided that no such special record
date may be less than 10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Issuers (or, upon the written request of the Issuers, the Trustee in the name and at the expense of the
Issuers) will send or cause to be sent to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. 

ARTICLE 3 
 REDEMPTION
AND PREPAYMENT 
 Section 3.01 Notices to Trustee. 

If the Issuers elect to redeem Notes pursuant to the optional redemption provisions of Section 3.07 hereof, they must furnish to the
Trustee, at least five Business Days (unless a shorter period is satisfactory to the Trustee) before a notice of such redemption is given pursuant to Section 3.03, an Officers’ Certificate setting forth the information to be stated in such
notice as provided in Section 3.03. 

  
 39 

 Section 3.02 Selection of Notes to Be Redeemed. 

If less than all of the Notes are to be redeemed at any time, the Trustee will select Notes for redemption as follows: 

 

	 	(1)	if the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange on which the Notes are listed; or 

 

	 	(2)	if the Notes are not listed on any national securities exchange, on a pro rata basis; or 

  

	 	(3)	in the case of Notes in global form, by such other method as DTC may prescribe. 

 No Notes of
$2,000 or less can be redeemed in part. In the event of partial redemption, the particular Notes to be redeemed will be selected, unless otherwise provided herein, not less than 15 nor more than 60 days prior to the redemption by the Trustee from
the outstanding Notes not previously called for redemption. 
 The Trustee will promptly notify the Issuers in writing of the Notes selected
for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except that
if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that
apply to Notes called for redemption also apply to portions of Notes called for redemption. 
 Section 3.03 Notice of Redemption. 

At least 15 days but not more than 60 days before a Redemption Date, the Issuers will mail or cause to be mailed, by first class mail, (or sent
electronically in the case of notices to DTC) a notice of redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be given 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 and discharge of this Indenture pursuant to Article 8 or 11 hereof. Notice of any redemption of the Notes (including upon an Equity Offering or in connection with a transaction
(or series of related transactions) that constitute a Change of Control) may, at the Issuers’ discretion, be given prior to the completion thereof and be subject to one or more conditions precedent, including, but not limited to, completed of
the related Equity Offering or Change of Control. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuers’ discretion, the Redemption Date may be delayed until
such time (including more than 60 days after the date the notice of redemption was delivered) as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such
conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date so delayed, or such notice may be rescinded at any time in the Issuers’ discretion if in the good faith judgment of the Issuers any or all of such
conditions will not be satisfied. 
 The notice will identify the Notes to be redeemed and will state: 

(1) the Redemption Date; 

(2) the redemption price, if then determinable and, if not, the manner of its determination; 

  
 40 

 (3) if any Note is being redeemed in part, the portion of the principal amount of
such Note to be redeemed and that, after the Redemption Date upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion will be issued in the name of the Holder thereof upon cancellation of the original
Note; 
 (4) the name and address of the Paying Agent; 

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price; 

(6) that, unless the Issuers default in making such redemption payment, interest on Notes called for redemption ceases to
accrue on and after the Redemption Date; 
 (7) the paragraph of the Notes and/or Section of this Indenture pursuant to which
the Notes called for redemption are being redeemed; 
 (8) any condition precedent to the redemption; and 

(9) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or
printed on the Notes. 
 At the Issuers’ request, the Trustee will give the notice of redemption in the Issuers’ names and
at their expense; provided, however, that the Issuers have delivered to the Trustee an Officers’ Certificate in accordance with Section 3.01 requesting that the Trustee give such notice and setting forth the information to be stated
in such notice as provided in the preceding paragraph. 
 Section 3.04 Effect of Notice of Redemption. 

Once notice of redemption is given in accordance with Section 3.03 hereof, Notes called for redemption without condition will become
irrevocably due and payable on the Redemption Date at the redemption price. 
 Section 3.05 Deposit of Redemption or Purchase Price. 

Prior to 11:00 a.m., Eastern Time, on the redemption or purchase date, the Issuers will deposit with the Trustee or with the Paying Agent money
sufficient to pay the redemption or purchase price of and accrued interest on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent will promptly return to the Issuers any money deposited with the Trustee or the Paying
Agent by the Issuers in excess of the amounts necessary to pay the redemption or purchase price of, and accrued interest on all Notes to be redeemed or purchased. 

If the Issuers comply with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest will cease to
accrue on the Notes or the portions of Notes called for redemption or accepted for purchase. If a Note is redeemed or purchased on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid
interest shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption or tendered for purchase is not so paid upon surrender for redemption or purchase because of
the failure of the Issuers to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid
principal, in each case at the rate provided in the Notes and in Section 4.01 hereof. 

  
 41 

 Section 3.06 Notes Redeemed or Purchased in Part. 

Upon surrender of a Note that is redeemed or purchased in part, the Issuers will issue and, upon receipt of an Authentication Order, the
Trustee will authenticate for the Holder at the expense of the Issuers a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered. 

Section 3.07 Optional Redemption. 

(a) At any time prior to August 1, 2019, the Issuers may on any one or more occasions redeem up to 35% of the
aggregate principal amount of Notes (including any Additional Notes) issued under this Indenture, upon prior notice in accordance with Section 3.02 hereof, at a redemption price of 106% of the principal amount thereof, plus accrued and unpaid
interest, if any, to, but excluding, the Redemption Date (subject to the right of Holders of Notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date), with an amount of cash
not greater than the net cash proceeds of one or more Equity Offerings by Holly Energy Partners; provided that:  

(1) at least 65% of the aggregate principal amount of Notes (including any Additional Notes) issued under this Indenture
(excluding Notes held by Holly Energy Partners and its Subsidiaries) remains outstanding immediately after the occurrence of such redemption; and 

(2) the redemption occurs within 180 days of the date of the closing of such Equity Offering. 

(b) Except pursuant to the preceding paragraph, subsection (d) of this Section 3.07, and Section 4.15(d) hereof,
the Notes will not be redeemable at the Issuers’ option prior to August 1, 2019. 
 (c) On or after August 1,
2019, the Issuers may redeem all or a part of the Notes, upon prior notice in accordance with Section 3.02 hereof, 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, but excluding, the applicable Redemption Date, if redeemed during the twelve-month period beginning on August 1 of each year indicated below, subject to the rights of Holders of Notes on the relevant record date to
receive interest due on an interest payment date that is on or prior to the Redemption Date: 
  

					
	 Year
	  	Percentage	 
	 2019
	  	 	104.500	% 
	 2020
	  	 	103.000	% 
	 2021
	  	 	101.500	% 
	 2018 and thereafter
	  	 	100.000	% 

 (d) At any time prior to August 1, 2019, the Issuers may also redeem all or a part
of the Notes, upon prior notice in accordance with Section 3.02 hereof, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest, if any, to, but excluding,
the date of redemption (the “Redemption Date”), subject to the rights of Holders on the relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date. The notice need not set
forth the Applicable Premium but only the manner of calculation of the redemption price. With respect to any redemption pursuant to this Section 3.07(d), Holly Energy Partners will (i) calculate the Treasury Rate on the second Business Day
preceding the applicable Redemption Date and (ii) prior to such Redemption Date file with the Trustee an Officers’ Certificate setting forth the Applicable Premium and the Treasury Rate and showing the calculation of each in reasonable
detail. The Trustee shall not be responsible for any such calculation. 

  
 42 

 (e) Any redemption pursuant to this Section 3.07 or Section 4.15(d)
shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof. 
 (f) Unless the Issuers default in the
payment of the redemption price, interest will cease to accrue on the Notes or portions thereof called for redemption on the applicable Redemption Date. 

Section 3.08 Mandatory Redemption. 

The Issuers are not required to make mandatory redemption or sinking fund payments with respect to the Notes. The Issuers are not prohibited
from acquiring the Notes by means other than a redemption, whether pursuant to a tender offer, open market purchase or otherwise, so long as the acquisition does not violate the terms of this Indenture. 

Section 3.09 Offer to Purchase by Application of Excess Proceeds. 

In the event that, pursuant to Section 4.10 hereof, the Issuers are required to commence an offer to all Holders to purchase Notes
(an “Asset Sale Offer”), it will follow the procedures specified below. 
 The Asset Sale Offer shall be made
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 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 Issuers 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. 
 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 Issuers will send, in the manner prescribed in
Section 12.02, 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 3.09 and Section 4.10 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 Issuers default in making such payment, any Note accepted for payment
pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase Date; 

  
 43 

 (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 Issuers, a
Depositary, if appointed by the Issuers, 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 Issuers, the depositary for the Asset Sale Offer 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 Notes and other pari passu Indebtedness to be purchased will be selected 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 Issuers so that only Notes in denominations of $2,000, or integral multiples of $1,000 in
excess 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). 
 On or
before the Purchase Date, the Issuers 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 Issuers in accordance with the terms of this Section 3.09. The Issuers, the depositary for the Asset Sale Offer 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 Issuers for purchase, and the Issuers will promptly issue a new Note, and the Trustee, upon written request
from the Issuers, 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 Issuers to the Holder thereof. The Issuers will publicly announce the results of the Asset Sale Offer on the Purchase Date. 

Other than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made pursuant to the
provisions of Sections 3.05 and 3.06 hereof.

Notes. 
 The Issuers will pay or cause to be paid the principal of, premium, if any, and interest on the Notes on the dates and in the

Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Issuers in respect of the Notes and this Indenture may be served. The Issuers will give prompt
written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuers fail to maintain any such required office or agency or fails to furnish the Trustee with the address thereof, such
presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 
 The Issuers may
also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such
designation or rescission will in any manner relieve the Issuers of their obligation to maintain an office or agency in the City of New York for such purposes. The Issuers will give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or agency. 
 The Issuers hereby designate the Corporate Trust

the time periods that would apply if Holly Energy Partners were required to file those reports with the SEC.

outstanding Notes shall have been accelerated in accordance with the terms of the Indenture and such acceleration has not been rescinded or cancelled prior to such cure. 

(b) For so long as any Notes remain outstanding, if at any time none of Holly Energy Partners and the Guarantors is required to
file with the SEC the reports required by paragraph (a) of this Section 4.03, Holly Energy Partners and the Guarantors will furnish to the Holders of Notes and to securities analysts and prospective investors, upon their request, the

the Issuers and Holly Energy Partners’ Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Issuers have kept, observed, performed and fulfilled their

are taking or propose to take with respect thereto. 
 Section 4.05 Taxes. 

Holly Energy Partners will pay, and will cause each of its Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and
governmental levies except such as are contested in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

 Section 4.06 Stay, Extension and Usury Laws. 

The Issuers and each of the Guarantors covenant (to the extent that they may lawfully do so) that they will not at any time insist upon, plead,
or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Issuers and
each of the Guarantors (to the extent that they may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and covenants that they will not, by resort to any such law, hinder, delay or impede the execution of any power
herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law has been enacted.

Payments for purposes of this clause (2) meaning only distributions on common units and subordinated units of Holly Energy Partners, plus the related distribution on the general partner interest), is less than the sum, without duplication, of:

 (A) $200.0 million less the aggregate amount of all Restricted Payments made by Holly Energy Partners and its
Restricted Subsidiaries pursuant to this clause (2)(A) during the period ending on the last day of the fiscal quarter immediately preceding the date of such Restricted Payment and beginning on the Prior Issue Date; plus 

(B) Incremental Funds to the extent not previously expended to this clause (2) or clause (1) above. 

  
 48 

 (b) The provisions of Section 4.07(a) hereof will not prohibit: 

(1) the payment of any dividend or distribution or the consummation of an irrevocable redemption of subordinated Indebtedness
within 60 days after the date of the declaration of such dividend or distribution, or the delivery of the irrevocable notice of redemption, as the case may be, if at the date of declaration or the date on which such irrevocable notice is delivered,
such dividend, distribution or redemption would have complied with the provisions of this Indenture (assuming, in the case of a redemption payment, the giving of the notice of such redemption payment would have been deemed to be a Restricted Payment
at such time and such deemed Restricted Payment would have been permitted at such time); 
 (2) the making of any
Restricted Payment in exchange for, or out of the net cash proceeds of, a substantially concurrent (a) capital contribution to Holly Energy Partners from any Person (other than a Restricted Subsidiary of Holly Energy Partners) or (b) sale
(other than to a Restricted Subsidiary of Holly Energy Partners) of Equity Interests (other than Disqualified Equity) of Holly Energy Partners, with a sale being deemed substantially concurrent if such Restricted Payment occurs not more than 120
days after such sale; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment will be excluded or deducted from the calculation of Available Cash from Operating Surplus and Incremental Funds;
 
 (3) the purchase, redemption, defeasance or other acquisition or retirement for value of any subordinated
Indebtedness of Holly Energy Partners or any Guarantor with the net cash proceeds from an incurrence of, or in exchange for, Permitted Refinancing Indebtedness; 

(4) the payment of any distribution or dividend by a Restricted Subsidiary of Holly Energy Partners to the holders of
its Equity Interests (other than Disqualified Equity) on a pro rata basis; 
 (5) so long as no Default
has occurred and is continuing or would be caused thereby, the repurchase, redemption or other acquisition or retirement for value of any Equity Interests of Holly Energy Partners or any Restricted Subsidiary of Holly Energy Partners held by any
current or former officer, director, consultant or employee of the General Partner (or its general partner), Holly Energy Partners or any of Holly Energy Partners’ Restricted Subsidiaries pursuant to any equity subscription agreement or plan,
stock or unit option agreement, shareholders’ agreement, employment agreement or similar agreement; provided, that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $5.0
million in any twelve-month period; provided further, that Holly Energy Partners may carry over and make in subsequent twelve-month periods, in addition to the amounts permitted for such twelve-month period, up to $2.0 million of unutilized
capacity under this clause (5) attributable to the immediately preceding twelve-month period; provided further, that such amount in any calendar year may be increased by an amount not to exceed (a) the cash proceeds received by
Holly Energy Partners from the sale of Equity Interests of Holly Energy Partners to members of management, employees or directors of the General Partner, Holly Energy Partners or its Restricted Subsidiaries that occurs after the Prior Issue Date (to
the extent the cash proceeds from the sale of such Equity Interests have not otherwise been applied to the payment of Restricted Payments by virtue of clauses 1(B) or 2(B) of Section 4.07(a) hereof), plus (b) the cash proceeds of
key man life insurance policies received by Holly Energy Partners after the Prior Issue Date, less (c) the amount of any Restricted Payments made pursuant to clauses (a) and (b) of this clause (5); 

(6) so long as no Default has occurred and is continuing or would be caused thereby, payments of dividends on Disqualified
Equity issued pursuant to Section 4.09 hereof; 

  
 49 

 (7) repurchases of Capital Stock deemed to occur upon exercise of stock options,
warrants or other convertible securities if such Capital Stock represents a portion of the exercise price of such options, warrants or other convertible securities; 

(8) cash payments in lieu of the issuance of fractional shares in connection with the exercise of warrants, options or other
securities convertible into or exchangeable for Capital Stock of Holly Energy Partners; or arising from stock dividends, splits or business combinations; 

(9) in connection with an acquisition by Holly Energy Partners or any of its Restricted Subsidiaries, the return to Holly
Energy Partners or any of its Restricted Subsidiaries of Equity Interests of Holly Energy Partners or any of its Restricted Subsidiaries constituting a portion of the purchase consideration in settlement of any indemnification claims or pursuant to
any purchase price adjustments under the acquisition agreement; and 
 (10) so long as no Default or Event of Default
has occurred and is continuing, the purchase, redemption, defeasance or other acquisition or retirement for value of any subordinated Indebtedness pursuant to Sections 4.10 or 4.15; provided that all Notes tendered by Holders in connection
with a Change of Control Offer or Asset Sale Offer, as applicable, have been purchased, redeemed, defeased or otherwise acquired or retired for value;  

The amount of all Restricted Payments (other than cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or
securities proposed to be transferred or issued by Holly Energy Partners or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment, except that the amount of any non-cash dividend or distribution paid in accordance with
clause (1) of Section 4.07(b) hereof shall be the Fair Market Value as of the date on which such dividend or distribution is declared. The Fair Market Value of any assets or securities that are required to be valued by this
Section 4.07 will be determined in the manner prescribed in the definition of that term. For the purposes of determining compliance with this Section 4.07, in the event that a Restricted Payment meets the criteria of more than one of the
categories of Restricted Payments described in the preceding clauses (1) through (10), Holly Energy Partners will be permitted to classify (or reclassify in whole or in part in its sole discretion) such Restricted Payment in any manner that
complies with this Section 4.07. 
 Section 4.08 Dividend and Other Payment Restrictions Affecting Subsidiaries. 

(a) Holly Energy Partners will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create
or permit to exist or become effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary that is not a Guarantor to: 

(1) pay dividends or make any other distributions on its Equity Interests to Holly Energy Partners or any of its Restricted
Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits, or pay any indebtedness owed to Holly Energy Partners or any of its Restricted Subsidiaries; provided that priority of any preferred equity
or similar Equity Interest in receiving dividends or liquidating distributions prior to the payment of dividends or liquidating distributions on common equity shall not be deemed to be a restriction on the ability to make distributions on Capital
Stock; 
 (2) make loans or advances to Holly Energy Partners or any of its Restricted Subsidiaries; or 

(3) sell, lease or transfer any of its properties or assets to Holly Energy Partners or any of its Restricted Subsidiaries.

  
 50 

 (b) The restrictions in Section 4.08(a) hereof will not apply to
encumbrances or restrictions existing under or by reason of: 
 (1) agreements as in effect on the Issue Date and any
amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements or the Indebtedness to which they relate; provided that the amendments, restatements, modifications, renewals,
supplements, refundings, replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend, distribution and other payment restrictions than those contained in those agreements on the Issue Date;

 (2) this Indenture, the Notes and the Note Guarantees; 

(3) agreements governing other Indebtedness permitted to be incurred under the provisions of the covenant described
above under Section 4.09 and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of such agreements; provided that the restrictions therein are not materially more restrictive,
taken as a whole, than those contained in this Indenture, the Notes and the Note Guarantees; 
 (4) applicable law,
rule, regulation or order; 
 (5) any instrument governing Indebtedness or Equity Interest of a Person acquired by
Holly Energy Partners or any of its Restricted Subsidiaries as in effect at the time of such acquisition (except to the extent such Indebtedness or Equity Interest was incurred in connection with or in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness
was permitted by the terms of this Indenture to be incurred; 
 (6) customary non-assignment provisions in
transportation agreements or purchase and sale or exchange agreements, pipeline and terminals agreements, or similar operational agreements or in licenses or leases, in each case entered into in the ordinary course of business; 

(7) purchase money obligations for property acquired in the ordinary course of business and Capital Lease Obligations that
impose restrictions on the property purchased or leased of the nature described in clause (3) of Section 4.08(a) hereof; 

(8) any agreement for the sale or other disposition of a Restricted Subsidiary that contains any such restrictions on that
Restricted Subsidiary pending its sale or other disposition; 
 (9) Permitted Refinancing Indebtedness;
provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being
refinanced; 
 (10) Liens permitted to be incurred under the provisions of Section 4.12 hereof that limit the
right of the debtor to dispose of the assets subject to such Liens; 
 (11) provisions limiting the disposition or
distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements and other similar agreements entered into in the ordinary course of business; 

  
 51 

 (12) any agreement or instrument relating to any property or assets acquired
after the Issue Date, so long as such encumbrance or restriction relates only to the property or assets so acquired and is not and was not created in anticipation of such acquisitions; 

(13) restrictions on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary
course of business; and 
 (14) encumbrances or restrictions contained in, or in respect of, Hedging Obligations permitted
under this Indenture from time to time. 
 Section 4.09 Incurrence of Indebtedness and Issuance of Disqualified Equity. 

(a) Holly Energy Partners will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly,
create, incur, issue, assume, Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”) any Indebtedness (including Acquired Debt), and Holly Energy Partners will
not issue any Disqualified Equity and will not permit any of its Restricted Subsidiaries to issue any Disqualified Equity; provided, however, that Holly Energy Partners and any Restricted Subsidiary may incur Indebtedness (including
Acquired Debt) and Holly Energy Partners and the Restricted Subsidiaries may issue Disqualified Equity, if the Fixed Charge Coverage Ratio for the Holly Energy Partners’ Reference Period immediately preceding the date on which such additional
Indebtedness is incurred or such Disqualified Equity is issued, as the case may be, would have been at least 2.00 to 1.00, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional
Indebtedness had been incurred or the Disqualified Equity had been issued, as the case may be, at the beginning of such Reference Period. 

(b) The provisions of Section 4.09(a) hereof will not prohibit the incurrence of any of the following items of
Indebtedness (collectively, “Permitted Debt”): 
 (1) the incurrence by Holly Energy Partners,
Finance Corp. and any Guarantor of additional Indebtedness and letters of credit and the guarantees thereof under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being
deemed to have a principal amount equal to the maximum potential liability of Holly Energy Partners and its Restricted Subsidiaries thereunder) not to exceed the greater of (a) $1.2 billion and (b) the sum of $850.0 million and 30% of
Consolidated Net Tangible Assets (determined as of the date of incurrence and after giving effect to the use of proceeds therefrom); 

(2) the incurrence by Finance Corp., Holly Energy Partners and its Restricted Subsidiaries of the Existing Indebtedness; 

(3) the incurrence by the Issuers and the Guarantors of Indebtedness represented by the Notes and the related Note Guarantees
to be issued on the Issue Date; 
 (4) the incurrence by Holly Energy Partners or any of its Restricted Subsidiaries of
Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of construction or improvement of property,
plant or equipment used in the business of Holly Energy Partners or any of its Restricted Subsidiaries, in an aggregate principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or
discharge any Indebtedness incurred pursuant to this clause (4), at any time outstanding not to exceed the greater of (a) $75.0 million and (b) 5.0% of Consolidated Net Tangible Assets (determined as of the date of incurrence and after
giving effect to the use of proceeds therefrom); 

  
 52 

 (5) the incurrence by Holly Energy Partners or any of its Restricted Subsidiaries
of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to refund, refinance or replace any Indebtedness (other than intercompany Indebtedness) that was permitted by this Indenture to be incurred under
Section 4.09(a) hereof or clauses (2), (3), (4) or (10) of this Section 4.09(b) or this clause (5); 

(6) the incurrence by Holly Energy Partners or any of its Restricted Subsidiaries of intercompany Indebtedness between
or among Holly Energy Partners and any of its Restricted Subsidiaries; provided, however, that: 
 (A) if Holly
Energy Partners or any Guarantor is the obligor on such Indebtedness and the payee is not Holly Energy Partners or a Guarantor, such Indebtedness must be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations
then due with respect to the Notes, in the case of Holly Energy Partners, or the Note Guarantee, in the case of a Guarantor; and 

(B) (1) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a
Person other than Holly Energy Partners or a Restricted Subsidiary of Holly Energy Partners and (2) any sale or other transfer of any such Indebtedness to a Person that is not either Holly Energy Partners or a Restricted Subsidiary of Holly
Energy Partners, 
 will be deemed, in each case, to constitute an incurrence of such Indebtedness by Holly Energy Partners or such
Restricted Subsidiary, as the case may be, that was not permitted by this clause (6); 
 (7) the incurrence by Holly Energy
Partners or any of its Restricted Subsidiaries of Hedging Obligations; 
 (8) the Guarantee by Holly Energy Partners,
or any of the Guarantors of (a) Indebtedness of Holly Energy Partners, or a Restricted Subsidiary of Holly Energy Partners that was permitted to be incurred by another provision of this Section 4.09 or (b) Indebtedness incurred by
Joint Ventures, provided that such Guarantee constitutes a Permitted Investment; and provided further, in each case, that if the Indebtedness being Guaranteed is subordinated to or pari passu with the Notes or the Note
Guarantees, then the Guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness Guaranteed;  

(9) the incurrence by Holly Energy Partners or any of its Restricted Subsidiaries of Indebtedness in respect of workers’
compensation claims, health or other types of social security benefits, unemployment or other insurance or self-insurance obligations, insurance contracts, reclamation, statutory obligations, bankers’ acceptances, and performance, payment,
appeal and surety bonds in the ordinary course of business, including Guarantees and obligations respecting standby letters of credit supporting such obligations, to the extent not drawn (in each case other than an obligation for money borrowed) and
replacements of any of the foregoing; 
 (10) the incurrence by Holly Energy Partners or any of its Restricted Subsidiaries
of Permitted Acquisition Indebtedness; 

  
 53 

 (11) the issuance by Holly Energy Partners or any of its Restricted
Subsidiaries of Disqualified Equity to Holly Energy Partners or any of its Restricted Subsidiaries, as the case may be; provided, however, that:  

(A) any subsequent issuance or transfer of Equity Interests of a Restricted Subsidiary that results in any such Disqualified
Equity being held, directly or indirectly, by a Person other than Holly Energy Partners or a Restricted Subsidiary of Holly Energy Partners; and 

(B) any sale or other transfer of any such Disqualified Equity to a Person that is not either Holly Energy Partners or a
Restricted Subsidiary of Holly Energy Partners; 
 will be deemed, in each case, to constitute an issuance of such Disqualified Equity by
Holly Energy Partners or such Restricted Subsidiary that was not permitted by this clause: 
 (12) the incurrence by Holly
Energy Partners or any of its Restricted Subsidiaries of Indebtedness in the ordinary course of business under documentary letters of credit which are to be repaid in full not more than one year after the date on which such Indebtedness was
originally incurred to finance the purchase of goods by Holly Energy Partners or any of its Restricted Subsidiaries; and 

(13) the incurrence by Holly Energy Partners or any of its Restricted Subsidiaries of additional Indebtedness in an aggregate
principal amount at any time outstanding, not to exceed the greater of (a) $75.0 million and (b) 5.0 % of Consolidated Net Tangible Assets (determined as of the date of incurrence and after giving effect to the use of proceeds
therefrom). 
 Holly Energy Partners will not incur, and will not permit Finance Corp. or any Guarantor to incur, any Indebtedness
(including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of Holly Energy Partners, Finance Corp. 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 shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of Holly Energy Partners,
Finance Corp. or any such Guarantor solely by virtue of being unsecured or by virtue of being secured on a first or junior Lien basis. 

For purposes of determining compliance with this Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of
more than one of the categories of Permitted Debt described in clauses (1) through (13) above, or is entitled to be incurred pursuant to Section 4.09(a) hereof, Holly Energy Partners 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 4.09. Indebtedness under Credit Facilities outstanding on the date on which Notes are
first issued and authenticated under this Indenture will initially be deemed to have been incurred on such date in reliance on the exception provided by clause (1) of the definition of Permitted Debt. 

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 Equity in the form of additional shares or units of
the same class of Disqualified Equity will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Equity for purposes of this Section 4.09; provided, in each such case, that the amount of any such accrual,
accretion or payment is included in Fixed Charges of Holly Energy Partners as accrued to the extent  

  
 54 

 
required by the definition of such term. Notwithstanding any other provision of this Section 4.09, the maximum amount of Indebtedness that Holly Energy Partners or any Restricted Subsidiary
may incur pursuant to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values. 

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 

(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. 

For purposes of determining compliance with 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 debt, or first committed, in the
case of revolving credit debt; 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 (i) the principal amount of such Indebtedness being refinanced plus (ii) the aggregate amount of fees, underwriting discounts, premiums and other costs and expenses incurred in connection with such refinancing.
The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in
which such respective Indebtedness is denominated that is in effect on the date of such refinancing. 
 Section 4.10 Asset Sales. 

Holly Energy Partners will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 

(1) Holly Energy Partners (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 (such Fair Market Value to be determined on the date of contractually agreeing to such Asset Sale and which shall give effect to
the assumption by another Person of any liabilities as provided for in (2)(A) below; and 
 (2) at least 75% of the
consideration received in the Asset Sale by Holly Energy Partners or such Restricted Subsidiary, together with the consideration received in all other Asset Sales by Holly Energy Partners or any Restricted Subsidiary since the Issue Date (on a
cumulative basis) is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash: 

  
 55 

 (A) any liabilities, as shown on Holly Energy Partners’ most recent
consolidated balance sheet, of Holly Energy Partners or any Restricted Subsidiary (other than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantees) that are assumed by the transferee of any
such assets pursuant to a novation agreement that releases Holly Energy Partners or such Restricted Subsidiary from further liability; 

(B) any securities, notes or other obligations received by Holly Energy Partners or any such Restricted Subsidiary from such
transferee that are within 90 days after the Asset Sale (subject to ordinary settlement periods), converted by Holly Energy Partners or such Restricted Subsidiary into cash, to the extent of the cash received in that conversion; 

(C) any stock or assets of the kind referred to in clauses (2) or (4) of the next succeeding paragraph; and 

(D) accounts receivable of a business retained by Holly Energy Partners or any of its Restricted Subsidiaries, as the case may
be, following the sale of such business, provided such accounts receivable (i) are not past due more than 60 days and (ii) do not have a payment date greater than 90 days from the date of the invoices creating such accounts
receivable. 
 Within 365 days after the receipt of any Net Proceeds from an Asset Sale, Holly Energy Partners (or the applicable Restricted
Subsidiary, as the case may be) may apply such Net Proceeds: 
 (1) to repay Senior Indebtedness of Holly Energy
Partners and/or its Restricted Subsidiaries (or to make an offer to repurchase or redeem such Indebtedness, provided that such repurchase or redemption closes within 45 days after the end of such 365-day period); 

(2) 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 Holly Energy Partners; 

(3) to make a capital expenditure; or 

(4) to acquire other assets that are not classified as current assets under GAAP and that are used or useful in a Permitted
Business. 
 Notwithstanding the foregoing, if within 365 days after the receipt of any Net Proceeds from an Asset Sale, Holly Energy
Partners (or the applicable Restricted Subsidiary, as the case may be) enters into a binding written agreement irrevocably committing Holly Energy Partners or such Restricted Subsidiary to an application of funds of the kind described in clause (2),
(3) or (4) of the preceding paragraph, and as to which the only condition to closing is the receipt of required governmental approvals or, in the case of clause (3), the completion of required construction of the applicable asset(s), Holly
Energy Partners or such Restricted Subsidiary shall be deemed not to be in violation of the preceding paragraph. Any Net Proceeds that are applied pursuant to clause (2) or (4) of the preceding paragraph pursuant to any such binding
agreement shall be deemed to have been applied for such purpose within such 365-day period so long as they are so applied within two years after the date of receipt of such Net Proceeds. 

Pending the final application of any Net Proceeds, Holly Energy Partners or any Restricted Subsidiary may temporarily reduce revolving credit
borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture. 

  
 56 

 Any Net Proceeds from Asset Sales that are not applied or invested as provided in the
second paragraph of this Section 4.10 will constitute “Excess Proceeds.” When the aggregate amount of Excess Proceeds exceeds $30.0 million, within five days thereof, the Issuers will make an Asset Sale Offer to all Holders of
Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this 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,
if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, Holly Energy Partners may use those Excess Proceeds for any purpose not otherwise prohibited by this 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 shall select the Notes and the representative of such other pari passu
Indebtedness will select 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. 

Holly Energy Partners will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of
Section 3.09 hereof or this Section 4.10, Holly Energy Partners will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.09 hereof or this
Section 4.10 by virtue of such compliance. 
 Section 4.11 Transactions with Affiliates. 

(a) Holly Energy Partners 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 Holly Energy Partners (each an “Affiliate Transaction”), if such Affiliate Transaction involves aggregate consideration in excess of $25.0 million, unless:  

(1) the Affiliate Transaction is on terms that are no less favorable to Holly Energy Partners or the relevant Restricted
Subsidiary than those that could have been obtained in a comparable transaction by Holly Energy Partners or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the Board of Directors of Holly Energy Partners, no
comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is fair and reasonable to Holly Energy Partners or the relevant Restricted Subsidiary from a financial or commercial point of view; and

 (2) Holly Energy Partners delivers to the Trustee with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $50.0 million, a resolution of the Board of Directors of Holly Energy Partners set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with clause
(1) of this Section 4.11(a) and that such Affiliate Transaction has been approved by either a Conflicts Committee of the Board of Directors of Holly Energy Partners (so long as a majority of the members of the Conflicts Committee approving
the Affiliate Transaction are disinterested) or a majority of the disinterested members of the Board of Directors of Holly Energy Partners 

  
 57 

 (b) The following items will not be deemed to be Affiliate Transactions and,
therefore, will not be subject to the provisions of Section 4.11(a) hereof: 
 (1) reasonable fees and compensation paid
to or for the benefit of any employee, officer or director of Holly Energy Partners, any of its Restricted Subsidiaries or the General Partner (or its general partner), and any employment agreement, employee benefit plan, officer or director
indemnification agreement or any similar arrangement entered into by Holly Energy Partners or any of its Restricted Subsidiaries existing on the Issue Date, or entered into thereafter in the ordinary course of business, and any indemnities or other
transactions permitted or required by bylaw, statutory provisions or any of the foregoing agreements, plans or arrangements; 

(2) transactions between or among Holly Energy Partners and/or its Restricted Subsidiaries; 

(3) transactions with a Person (other than an Unrestricted Subsidiary of Holly Energy Partners) that is an Affiliate of Holly
Energy Partners solely because Holly Energy Partners owns, directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person; 

(4) any issuance of Equity Interests (other than Disqualified Equity) of Holly Energy Partners to Affiliates of Holly Energy
Partners; 
 (5) Restricted Payments or Permitted Investments that do not violate Section 4.07 hereof; 

(6) customary compensation, indemnification and other benefits made available to officers, directors or employees of Holly
Energy Partners, a Restricted Subsidiary of Holly Energy Partners or the General Partner, including reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and directors’ liability insurance; 

(7) in the case of processing, gathering, transportation, marketing, hedging, production handling, operating, construction,
terminalling, storage, lease, platform use, or other operational contracts, any such contracts are entered into in the ordinary course of business on terms substantially similar to those contained in similar contracts entered into by Holly Energy
Partners or any Restricted Subsidiary and third parties, or if neither Holly Energy Partners nor any Restricted Subsidiary has entered into a similar contract with a third party, that the terms are no less favorable than those available from third
parties on an arm’s-length basis, as determined in good faith by either the Conflicts Committee of the Board of Directors of Holly Energy Partners (so long as a majority of the members of the Conflicts Committee approving the Affiliate
Transaction are disinterested) or a majority of the disinterested members of the Board of Directors of Holly Energy Partners; 

(8) loans or advances to employees in the ordinary course of business not to exceed $5.0 million in the aggregate at any one
time outstanding; 
 (9) the existence of, or the performance by Holly Energy Partners or any Restricted Subsidiary of
its obligations under the terms of, any agreements that are described in the Holly Energy Partners’ Annual Report on Form 10-K for the fiscal year ended December 31, 2015 under the heading “Certain Relationships and Related
Transactions, and Director Independence” to which it is a party as of the date of the Offering Memorandum and any amendments thereto and any similar agreements which it may enter into thereafter; provided, however, that the existence of,
or the performance by Holly Energy Partners or any Restricted Subsidiary of its obligations under, any future amendment to such agreements or under any such similar  

  
 58 

 
agreements shall only be permitted by this clause (9) to the extent that the terms of any such amendment or new agreement, taken as a whole, are not less favorable to the Holders in any
material respect as determined in good faith by either the Conflicts Committee of the Board of Directors of Holly Energy Partners (so long as a majority of the members of the Conflicts Committee approving the Affiliate Transaction are disinterested)
or a majority of the disinterested members of the Board of Directors of Holly Energy Partners; 
 (10) Guarantees of
performance by Holly Energy Partners or any of its Restricted Subsidiaries in the ordinary course of business, except for guarantees of Indebtedness in respect of borrowed money;

Holly Energy Partners will not and will not permit any Guarantor to, create, incur, assume or otherwise cause or suffer to exist or become

(1) in the case of Liens securing Indebtedness of Holly Energy Partners or a Guarantor, the Notes or Note Guarantees, as
applicable, are contemporaneously secured by a Lien on such property or assets on a senior basis to the subordinated Indebtedness so secured with the same priority that the Notes or Note Guarantees, as applicable, have to such subordinated

 Section 4.13 Limitations on Finance Corp. Activities. 

Finance Corp. will not hold any material assets, become liable for any material obligations or engage in any significant business activities;
provided, that Finance Corp. may be a co-obligor or guarantor with respect to Indebtedness if Holly Energy Partners is an obligor on such Indebtedness and the net proceeds of such Indebtedness are received by Holly Energy Partners, Finance
Corp. or one or more Guarantors. At any time after Holly Energy Partners is a corporation, Finance Corp. may consolidate or merge with or into Holly Energy Partners or any Restricted Subsidiary. 

Section 4.14 Corporate Existence. 

Subject to Article 5 hereof, Holly Energy Partners shall do or cause to be done all things necessary to preserve and keep in full force and
effect:

Subsidiaries, in accordance with the respective organizational documents (as the same may be amended from time to time) of Holly Energy Partners or any such Subsidiary; and 

(2) the rights (charter and statutory), licenses and franchises of Holly Energy Partners and its Subsidiaries;
provided, however, that Holly Energy Partners shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of its Subsidiaries, if the General Partner shall determine that the
preservation thereof is no longer desirable in the conduct of the business of Holly Energy Partners and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders of the Notes.  

Section 4.15 Offer to Repurchase Upon Change of Control. 

(a) Upon the occurrence of a Change of Control, the Issuers will make an offer (a “Change of Control
Offer”) to each Holder of Notes 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 in cash equal to 101% of the aggregate principal amount of
Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to, but excluding, the date of purchase (the “Change of Control Payment”), subject to the rights of Holders of Notes on the relevant record date
to receive interest due on an interest payment date that is on or prior to the date of purchase. Within 30 days following any Change of Control, the Issuers will send a notice to each Holder describing the transaction or transactions that constitute
the Change of Control and stating: 
 (1) that the Change of Control Offer is being made pursuant to this
Section 4.15 and that all Notes tendered will be accepted for payment; 
 (2) the purchase price and the
purchase date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is sent (the “Change of Control Payment Date”);  

(3) that any Note not tendered will continue to accrue interest; 

(4) that, unless the Issuers Default in the payment of the Change of Control Payment, all Notes accepted for payment pursuant
to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 
 (5) that Holders
electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry
transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date; 

  
 60 

 (6) that Holders will be entitled to withdraw their election if the Paying Agent
receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered
for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and 
 (7) that
Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion must be equal to $2,000 in principal amount or an integral
multiple of $1,000 in excess thereof. 
 The Issuers 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 in Control. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of this Section 4.15, the Issuers will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.15 by virtue of such
compliance. 
 (b) On the Change of Control Payment Date, the Issuers 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 Issuers. 

The Paying Agent will promptly mail to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all
the Notes are then in global form, it will make such payment through the facilities of DTC), 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; provided, that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Issuers will publicly announce the results of the Change of
Control Offer on or as soon as practicable after the Change of Control Payment Date. 
 The provisions described above that require
the Issuers to make a Change of Control Offer following a Change of Control will be applicable whether or not any other provisions of this Indenture are applicable. 

(c) Notwithstanding anything to the contrary in this Section 4.15, the Issuers 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 Section 4.15 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 3.07 hereof, unless and until there is a default in payment of the applicable redemption price. 

  
 61 

 (d) With respect to the Notes, in the event that Holders of not less than 90% of
the aggregate principal amount of the outstanding Notes tender and do not withdraw such Notes in a Change of Control Offer and Holly Energy Partners (or the third party making the Change of Control Offer as provided above) purchases all of the Notes
validly tendered and not withdrawn by such Holders, the Issuers will have the right, upon not less than 15 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control Offer described
above, to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to 101% of the aggregate principal amount of such Notes, plus accrued and unpaid interest on the Notes that remain outstanding to, but
excluding, the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on an Interest Payment Date that is on or prior to the Redemption Date). 

Section 4.16 [Reserved.] 
 Section 4.17
[Reserved.] 
 Section 4.18 Additional Guarantees. 

If, after the Issue Date, any wholly-owned Domestic Subsidiary (other than Finance Corp.) of Holly Energy Partners that is not already a
Guarantor Guarantees any other Indebtedness of either of the Issuers under a Credit Facility in an aggregate principal amount in excess of $50.0 million, then that Subsidiary will become a Guarantor by executing and delivering a supplemental
indenture to this Indenture to the Trustee within 30 Business Days of the date on which it Guaranteed or incurred such Indebtedness; provided that the preceding shall not apply to Subsidiaries of Holly Energy Partners that have been properly
designated as Unrestricted Subsidiaries in accordance with this Indenture for so long as they continue to constitute Unrestricted Subsidiaries. Notwithstanding the preceding, any Note Guarantee of a Domestic Subsidiary that was incurred pursuant to
this Section 4.18 will be released in accordance with Section 10.05 hereof. 
 Section 4.19 Designation of Restricted and
Unrestricted Subsidiaries. 
 The Board of Directors of Holly Energy Partners 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 Holly Energy Partners 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 either reduce the amount available for Restricted Payments under Section 4.07 hereof or
qualify as a Permitted Investment under one or more clauses of the definition of Permitted Investments, as determined by Holly Energy Partners; provided that any 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. 
 Any designation of a
Subsidiary of Holly Energy Partners 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 4.07 hereof. 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 Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary of Holly Energy Partners as of such date and, if
such Indebtedness is not permitted to be incurred as of such date under Section 4.09 hereof, Holly Energy Partners will be in default of such covenant. The Board of Directors of Holly 

  
 62 

 
Energy Partners may at any time designate any Unrestricted Subsidiary to be a Restricted Subsidiary of Holly Energy Partners; provided that such designation will be deemed to be an
incurrence of Indebtedness by a Restricted Subsidiary of Holly Energy Partners of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only be permitted if (1) such Indebtedness is permitted under
Section 4.09 hereof, calculated on a pro forma basis as if such designation had occurred at the beginning of the Reference Period; and (2) no Default or Event of Default would be in existence following such designation.  

Section 4.20 Termination of Covenants. 

(a) If at any time (i) the Notes are assigned an Investment Grade Rating from both Rating Agencies and (ii) no
Default or Event of Default has occurred and is continuing under this Indenture (the “Termination Date”), Holly Energy Partners and its Restricted Subsidiaries will no longer be subject to the following provisions of this
Indenture: 
 (1) Section 4.10; 

(2) Section 4.07; 

(3) Section 4.09; 

(4) Section 4.18; 

(5) Section 4.11; 

(6) Section 4.13; 

(7) Clause 4 of Section 5.01; and 

(8) Section 4.08. 

(b) However, Holly Energy Partners and its Restricted Subsidiaries will remain subject to the provisions of this Indenture:

 (1) Section 4.03; 

(2) Section 4.12; and 

(3) Section 5.01 (with the exception of clause (4) thereof). 

No Subsidiary may be designated as an Unrestricted Subsidiary after the Termination Date.

merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made shall succeed to, and be substituted for (so that from and after the date of such consolidation, merger, sale, assignment, transfer, lease, conveyance
or other disposition, the provisions of this Indenture referring to the “Holly Energy Partners” shall refer instead to the successor Person and not to Holly Energy Partners), and may exercise every right and power of Holly Energy Partners
under this Indenture with the same effect as if such successor Person had been named as Holly Energy Partners herein. 
 ARTICLE 6

Guarantee now exists, or is created after the Issue Date, if that default:

Section 6.02 Acceleration. 
 In the
case of an Event of Default specified in clause (8) or (9) of Section 6.01 hereof, with respect to Finance Corp., Holly Energy Partners or any Restricted Subsidiary of Holly Energy Partners that is a Significant Subsidiary or any
group of Restricted Subsidiaries of Holly Energy Partners 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. 

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 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 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. 
 Section 6.03 Other Remedies. 

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

  
 67 

 The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not
produce any of them in the proceeding. A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in
the Event of Default. All remedies are cumulative to the extent permitted by law. 
 Section 6.04 Waiver of Past Defaults. 

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 waive an existing Default or Event of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium or interest on the Notes (including in connection with an
offer to purchase); provided, however, that the Holders of a majority in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment default that resulted from such
acceleration. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon. 
 Section 6.05 Control by Majority. 

Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture that the Trustee determines may be
unduly prejudicial to the rights of other Holders of Notes or that may involve the Trustee in personal liability. 
 Section 6.06 Limitation on
Suits. 
 A Holder may pursue a remedy with respect to this Indenture or the Notes only if: 

(1) such Holder gives to the Trustee written notice that an Event of Default is continuing; 

(2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes make a written request to the Trustee
to pursue the remedy; 
 (3) such Holder or Holders offer and, if requested, provide to the Trustee security or indemnity
reasonably satisfactory to the Trustee against any loss, liability or expense; 
 (4) the Trustee does not comply with the
request within 60 days after receipt of the request and the offer of security or indemnity; and 
 (5) during such 60-day
period, Holders of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request. 

A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a Note or to obtain a preference or priority over
another Holder of a Note. 
 Section 6.07 Rights of Holders of Notes to Receive Payment. 

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium and interest
and on the Note, on or after the respective due dates expressed in the Note (including in connection with an offer to purchase), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder. 

  
 68 

 Section 6.08 Collection Suit by Trustee. 

If an Event of Default specified in Section 6.01(1) or (2) hereof occurs and is continuing, the Trustee is authorized to recover
judgment in its own name and as trustee of an express trust against the Issuers for the whole amount of principal of, premium and interest remaining unpaid on, the Notes and interest on overdue principal and, to the extent lawful, interest and such
further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

Section 6.09 Trustee May File Proofs of Claim. 

The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the
claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Issuers (or any
other obligor upon the Notes), their creditors or their property and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any custodian in any such judicial
proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the
reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof. To the extent that the payment of any such compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by
a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or
arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes
or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. 
 Section 6.10

 Section 7.01
Duties of Trustee. 
 (a) If an Event of Default has occurred and is continuing, the Trustee will exercise such of the
rights and powers vested in it by this Indenture, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. 

(b) Except during the continuance of an Event of Default: 

(1) the duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need
perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and 

(2) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the
correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will examine the certificates and opinions to determine whether or not
they conform to the requirements of this Indenture. 
 (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful misconduct, except that: 
 (1) this paragraph does
not limit the effect of paragraph (b) of this Section 7.01; 
 (2) the Trustee will not be liable for any error of
judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was negligent in ascertaining the pertinent facts; and 

(3) the Trustee will not be liable with respect to any action it takes or omits to take in good faith in accordance with a
direction received by it pursuant to Section 6.05 hereof.

(e) No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee
will be under no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder has furnished to the Trustee security and indemnity satisfactory to it against any loss, liability or
expense. 

  
 70 

 (f) The Trustee will not be liable for interest on any money received by it
except as the Trustee may agree in writing with the Issuers. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. 

Section 7.02 Rights of Trustee. 

(a) The Trustee may conclusively rely upon any document believed by it to be genuine and to have been signed or presented by
the proper Person. The Trustee need not investigate any fact or matter stated in the document. 
 (b) Before the Trustee acts
or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion
of Counsel. The Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it
hereunder in good faith and in reliance thereon.

responsible for the misconduct or negligence of any agent appointed with due care.

sufficient if signed by an Officer of each of the Issuers. 
 (f) The Trustee will be under no obligation to exercise any of
the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders have furnished to the Trustee reasonable indemnity or security against the losses, liabilities and expenses that might be
incurred by it in compliance with such request or direction. 
 Section 7.03 Individual Rights of Trustee. 

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuers or any
Affiliate of the Issuers with the same rights it would have if it were not Trustee. However, in the event that the Trustee acquires any conflicting interest (as such term is defined in the TIA) it must eliminate such conflict within 90 days or
resign. Any Agent may do the same with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof. 
 Section 7.04
Trustee’s Disclaimer. 
 The Trustee will not be responsible for and makes no representation as to the validity or adequacy of
this Indenture or the Notes, it shall not be accountable for the Issuers’ use of the proceeds from the Notes or any money paid to the Issuers or upon the Issuers’ direction under any provision of this Indenture, it will not be responsible
for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection with the sale of the
Notes or pursuant to this Indenture other than its certificate of authentication.

 Section 7.05 Notice of Defaults. 

If a Default or Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee will send to Holders of Notes a notice
of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as a
committee of its Responsible Officers in good faith determines that withholding the notice is in the interests of the Holders of the Notes. 

Section 7.06 Reports by Trustee to Holders of the Notes. 

(a) Within 60 days after each May 15 beginning with the May 15 following the date of this Indenture, and for so long
as Notes remain outstanding, the Trustee will send to the Holders of the Notes a brief report dated as of such reporting date that complies with TIA § 313(a) (but if no event described in TIA § 313(a) has occurred within the
twelve months preceding the reporting date, no report need be transmitted). The Trustee also will comply with TIA § 313(b)(2). The Trustee will also transmit, in the manner prescribed in Section 12.02, all reports as required by TIA
§ 313(c). 
 (b) A copy of each report at the time it is sent to the Holders of Notes will be sent by the Trustee
to the Issuers and filed by the Trustee with the SEC and each stock exchange on which the Notes are listed in accordance with TIA § 313(d). The Issuers will promptly notify the Trustee when the Notes are listed on any stock exchange. 

Section 7.07 Compensation and Indemnity. 

(a) The Issuers will pay to the Trustee from time to time reasonable compensation for its acceptance of this Indenture and
services hereunder. The Trustee’s compensation will not be limited by any law on compensation of a trustee of an express trust. The Issuers will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses
incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel. 

(b) The Issuers and the Guarantors will indemnify the Trustee against any and all losses, liabilities or expenses incurred by
it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the Issuers and the Guarantors (including this Section 7.07) and
defending itself against any claim (whether asserted by the Issuers, the Guarantors, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such
loss, liability or expense may be attributable to its negligence or bad faith. The Trustee will notify the Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuers will not relieve the Issuers or
any of the Guarantors of their obligations hereunder. The Issuers or such Guarantor will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Issuers will pay the reasonable fees and expenses
of such counsel. Neither the Issuers nor any Guarantor need pay for any settlement made without its consent, which consent will not be unreasonably withheld. 

(c) The obligations of the Issuers and the Guarantors under this Section 7.07 will survive the satisfaction and discharge
of this Indenture. 
 (d) To secure the Issuers’ and the Guarantors’ payment obligations in this Section 7.07,
the Trustee will have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien will survive the satisfaction and discharge of this
Indenture. 

  
 72 

 (e) When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(8) or (9) hereof occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any
Bankruptcy Law. 
 (f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent applicable.

 Section 7.08 Replacement of Trustee. 

(a) A resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the
successor Trustee’s acceptance of appointment as provided in this Section 7.08. 
 (b) The Trustee may resign in
writing at any time and be discharged from the trust hereby created by so notifying the Issuers. The Holders of a majority in aggregate principal amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the Issuers
in writing. The Issuers may remove the Trustee if: 
 (1) the Trustee fails to comply with Section 7.10 hereof; 

(2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any
Bankruptcy Law; 
 (3) a custodian or public officer takes charge of the Trustee or its property; or 

(4) the Trustee becomes incapable of acting. 

(c) If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Issuers will
promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee
appointed by the Issuers. 
 (d) If a successor Trustee does not take office within 60 days after the retiring Trustee
resigns or is removed, the retiring Trustee, the Issuers, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor Trustee. 

(e) If the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with
Section 7.10 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee. 

(f) A successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Issuers.
Thereupon, the resignation or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee will send a notice of its
succession to Holders. The retiring Trustee will promptly transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been paid and subject to the Lien provided for in
Section 7.07 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.08, the Issuers’ obligations under Section 7.07 hereof will continue for the benefit of the retiring Trustee. 

  
 73 

 Section 7.09 Successor Trustee by Merger, etc. 

If the Trustee consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business to, another
corporation, the successor corporation without any further act will be the successor Trustee. 
 Section 7.10 Eligibility; Disqualification.

 There will at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States of
America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that is subject to supervision or examination by federal or state authorities and that has a combined capital and surplus of at least $100.0
million as set forth in its most recent published annual report of condition. 
 This Indenture will always have a Trustee who satisfies the
requirements of TIA § 310(a)(1), (2) and (5). The Trustee is subject to TIA § 310(b). 
 Section 7.11 Preferential
Collection of Claims Against the Issuers.

in TIA § 311(b). A Trustee who has resigned or been removed shall be subject to TIA § 311(a) to the extent indicated therein. 

ARTICLE 8 
 LEGAL
DEFEASANCE AND COVENANT DEFEASANCE 
 Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance. 

The Issuers may at their option and at any time, elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes and
Note Guarantees upon compliance with the conditions set forth below in this Article 8. 
 Section 8.02 Legal Defeasance and Discharge. 

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Issuers and each
of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 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 Issuers 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 8.05 hereof and the other Sections of this 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 Indenture (and the Trustee, on demand of and at the expense of the Issuers, shall execute proper instruments acknowledging
the same), except for the following provisions which will survive until otherwise terminated or discharged hereunder: 

  
 74 

 (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 8.04 hereof; 

(2) the Issuers’ obligations with respect to the Notes concerning issuing temporary Notes, registration of Notes,
mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust; 

(3) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Issuers’ and the Guarantors’
obligations in connection therewith; and 
 (4) this Article 8. 

Subject to compliance with this Article 8, the Issuers may exercise their option under this Section 8.02 notwithstanding the prior
exercise of its option under Section 8.03 hereof. 
 Section 8.03 Covenant Defeasance. 

Upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Issuers and each
of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections 4.03, 4.04, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13,
4.15, 4.18 and 4.19 hereof and clause (4) of Section 5.01 hereof with respect to the outstanding Notes, and the Guarantors will be released from their obligations with respect to the Note Guarantees, on and after the date the conditions
set forth in Section 8.04 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 to the extent permitted by GAAP). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees, the Issuers 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 6.01 hereof, but, except as specified above, the remainder of this Indenture and such Notes and Note Guarantees will
be unaffected thereby. In addition, upon the Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Sections
6.01(3) through 6.01(7) inclusive hereof will not constitute Events of Default. 
 Section 8.04 Conditions to Legal or Covenant
Defeasance. 
 In order to exercise either Legal Defeasance or Covenant Defeasance under either Section 8.02 or 8.03 hereof: 

(1) the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S.
dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in 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, or interest and premium, if any, on the outstanding Notes on the stated date for payment thereof or on the applicable Redemption Date, as the case may be, and the Issuers must specify whether
the Notes are being defeased to such stated date for payment or to a particular Redemption Date; 

  
 75 

 (2) in the case of an election under Section 8.02 hereof, the Issuers must
deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that: 
 (A) the Issuers have
received from, or there has been published by, the Internal Revenue Service a ruling; or 
 (B) since the Issue Date, 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; 
 (3) in the case of an
election under Section 8.03 hereof, the Issuers must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming that 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 incurrence of Indebtedness or other borrowing of funds or the grant of Liens securing such Indebtedness or other borrowing, all or a portion of the proceeds of which will be applied to such deposit) and the
deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which the Issuers or any Guarantor is a party or by which the Issuers or any Guarantor is bound; 

(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 Indenture) to which Holly Energy Partners or any of its Subsidiaries is a party or by which Holly Energy Partners or any of its Subsidiaries is bound; 

(6) the Issuers must deliver to the Trustee an Officers’ Certificate stating that the deposit was not made by the Issuers
with the intent of preferring the Holders of Notes over the other creditors of the Issuers with the intent of defeating, hindering, delaying or defrauding any creditors of the Issuers or others; and 

(7) the Issuers must deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all
conditions precedent relating to the Legal Defeasance or the Covenant Defeasance have been complied with.

 Section 8.05 Deposited Money and Government Securities to be Held in Trust; Other
Miscellaneous Provisions. 
 Subject to Section 8.06 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 8.05, the “Trustee”) pursuant to Section 8.04 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 Indenture, to the payment, either directly or through any Paying Agent (including either Issuer 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 Issuers 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 8.04 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 8 to the contrary, the Trustee will deliver or pay to the Issuers from time to time upon the request
of the Issuers any money or non-callable Government Securities held by it as provided in Section 8.04 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 8.04(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. 

Section 8.06 Repayment to the Issuers. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, 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 Issuers on their request or (if then held by the Issuers) will be
discharged from such trust; and the Holder of such Note will thereafter be permitted to look only to the Issuers for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the
Issuers as trustee thereof, will thereupon cease; provided, however, that, if any Definitive Note is then outstanding, the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuers 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 Issuers. 
 Section 8.07 Reinstatement. 

If the Trustee or Paying Agent is unable to apply any U.S. dollars or non-callable Government Securities in accordance with
Section 8.02 or 8.03 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 Issuers’ and the Guarantors’
obligations under this Indenture and the Notes and the Note Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply
all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided, however, that, if the Issuers make any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its
obligations, the Issuers will 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.

Except as provided below in this Section 9.02, the Issuers, the Guarantors and the Trustee may amend or supplement this Indenture
(including, without limitation, Sections 3.09, 4.10 and 4.15 hereof) and the Notes and the Note Guarantees with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes (including, without limitation,
Additional Notes, if any), including, without limitation, consents obtained in connection with a tender offer or exchange offer for, or purchase of, the Notes, and, subject to Sections 6.04 and 6.07 hereof, any existing Default or Event of Default

(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 interest or premium, if any, on the Notes (except a

(5) make any Note payable in money other than that stated in the Notes; 

(6) make any change in the provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes
to receive payments of, principal of, or interest or premium, if any, on, the Notes (other than as permitted by clause (7) below); 

(7) waive a redemption payment with respect to any Note (other than a payment required by Sections 3.09 and 4.10 or

Section 9.05 hereof, the Trustee 

  
 79 

 
will join with the Issuers 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 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 be necessary for the consent of the Holders of Notes under this Section 9.02 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 9.02 becomes effective, the Issuers will send to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuers to send 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. 
 Section 9.03
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 (except as provided in the second succeeding paragraph) and thereafter binds every Holder. 

The Issuers may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any
amendment, supplement or waiver. If a record date is fixed, then notwithstanding the second to last sentence of the immediately preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies) and only those
Persons, shall be entitled to consent to such amendment or waiver or revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. 

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of the
clauses (1) through (9) of Section 9.02, in which case, the amendment, supplement or waiver shall bind only each Holder of a note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the
same indebtedness as the consenting Holder’s Note. 
 Section 9.04 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 Issuers in
exchange for all Notes may issue and the Trustee shall, upon receipt of an Authentication Order, 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.

  
 80 

 Section 9.05 Trustee to Sign Amendments, etc. 

The Trustee will sign any amended or supplemental indenture authorized pursuant to this Article 9 if the amendment or supplement does not
adversely affect the rights, duties, liabilities or immunities of the Trustee. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject to Section 7.01 hereof) will be fully protected in relying
upon, in addition to the documents required by Section 12.04 hereof, an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized or permitted by this Indenture. 

ARTICLE 10 
 NOTE
GUARANTEES 
 Section 10.01 Guarantee. 

(a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally, unconditionally guarantees to each Holder
of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Issuers hereunder or thereunder, that:

 (1) the principal of, premium, if any, and interest on, the Notes will be promptly paid in full when due, whether at
Stated Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Issuers to the Holders or the Trustee hereunder or thereunder will be
promptly paid in full or performed, all in accordance with the terms hereof and thereof; and 
 (2) in case of any extension
of time of payment or renewal of any Notes or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or
otherwise. 
 Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors will
be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 

(b) The Guarantors hereby agree that their obligations hereunder are unconditional, irrespective of the validity, regularity or
enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers, any
action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in
the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenants that its Note Guarantee will not be discharged except by complete performance
of the obligations contained in the Notes and this Indenture. 
 (c) If any Holder or the Trustee is required by any court or
otherwise to return to the Issuers, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Issuers or the Guarantors, any amount paid by either to the Trustee or such Holder, each Note
Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect. 
 (d) Each Guarantor agrees
that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the
Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Section 10.01,

  
 81 

 
notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of
acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due and payable by the Guarantors for the purposes of this Section 10.01. The Guarantors will have the
right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee. 

Section 10.02 Limitation on Guarantor Liability. 

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirm that it is the intention of all such parties that the Note
Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to
any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount that will, after giving effect to such
maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other
Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance. 

Section 10.03 Execution and Delivery of Notation of Note Guarantee. 

To evidence its Note Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee
substantially in the form attached as Exhibit E hereto will be endorsed by an Officer of such Guarantor on each Note authenticated and delivered by the Trustee and that this Indenture (including any supplement thereto) will be executed on behalf of
such Guarantor by one of its Officers. 
 Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 hereof will
remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee. 
 If an Officer
whose signature is on this Indenture or on the notation of its Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which such notation of its Note Guarantee is endorsed, the Note Guarantee will be valid
nevertheless. 
 The delivery of any Note by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the
Note Guarantee set forth in this Indenture on behalf of the Guarantors. 
 In the event that the Issuers or any of Holly Energy
Partners’ Restricted Subsidiaries creates or acquires any wholly-owned Domestic Subsidiary after the date of this Indenture, if required by Section 4.18 hereof, the Issuers will cause such Domestic Subsidiary to comply with the provisions
of Section 4.18 hereof and this Article 10, to the extent applicable. 
 Section 10.04 Guarantors May Consolidate, etc., on Certain Terms.

 Except as otherwise provided in Section 10.05 hereof, no Guarantor may sell or otherwise dispose of all or substantially all of its
assets to, or consolidate with or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Issuers or another Guarantor, unless: 

  
 82 

 (1) immediately after giving effect to such transaction, no Default or Event of
Default exists; and 
 (2) either: 

(A) the Person acquiring the properties or assets in any such sale or disposition or the Person formed by or surviving any such
consolidation or merger is a Guarantor, or unconditionally assumes all the obligations of that Guarantor under this Indenture and its Note Guarantee on the terms set forth herein or therein, pursuant to a supplemental indenture in form and substance
reasonably satisfactory to the Trustee; or 
 (B) the Net Proceeds of such sale or other disposition are applied in
accordance with the applicable provisions of this Indenture, including without limitation, Section 4.10 hereof. 
 In case of any such
consolidation, merger, sale or conveyance and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Note Guarantee endorsed upon the Notes and
the due and punctual performance of all of the covenants and conditions of this Indenture to be performed by the Guarantor, such successor Person will succeed to and be substituted for the Guarantor with the same effect as if it had been named
herein as a Guarantor. Such successor Person thereupon may cause to be signed any or all of the notations of Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by the Issuers and
delivered to the Trustee. All the Note Guarantees so issued will in all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance with the terms of this Indenture as
though all of such Note Guarantees had been issued at the date of the execution hereof. 
 Section 10.05 Releases. 

(a) In the event of any sale or other disposition (i) of all or substantially all of the properties or assets of any Guarantor, by
way of merger, consolidation or otherwise, to a Person that is not (either before or after giving effect to such transactions) Holly Energy Partners or a Restricted Subsidiary of Holly Energy Partners, or (ii) of all of the Capital Stock of any
Guarantor after which the applicable Guarantor is no longer a Restricted Subsidiary of Holly Energy Partners, then such Guarantor will be released and relieved of any obligations under its Note Guarantee and all of its other obligations under this
Indenture; provided that such sale or other disposition does not violate the applicable provisions of Section 4.10 hereof. Upon delivery by the Issuers to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the
effect that such sale or other disposition was made by the Issuers in accordance with the provisions of this Indenture, including without limitation Section 4.10 hereof, the Trustee will execute any documents reasonably required in order to
evidence the release of any Guarantor from its obligations under its Note Guarantee and all of its other obligations under this Indenture.  

(b) Upon designation of any Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture, such Guarantor will be
released and relieved of any obligations under its Note Guarantee and all of its other obligations under this Indenture. 
 (c) Upon release
or discharge of the Guarantee by any Guarantor with respect to Indebtedness under a Credit Facility or the Guarantee that resulted in the creation of a Note Guarantee, such Guarantor will be released and relieved of any obligations under its Note
Guarantee and its other obligations under this Indenture; provided, however, that release or discharge of the Guarantee by such Guarantor with respect to Indebtedness under the Existing Senior Notes occurs prior to or

  
 83 

 
contemporaneously therewith; provided, further, however that if, at any time following such release, that Guarantor later Guarantees Indebtedness of either Issuer under a Credit Facility,
then such Guarantor shall be required to provide a Note Guarantee at such time if required in accordance with Section 4.18 hereof. 

(d) Upon Legal or Covenant Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance with
Article 11 hereof, each Guarantor will be released and relieved of any obligations under its Note Guarantee and all of its other obligations under this Indenture. 

(e) Upon the merger, amalgamation or consolidation of any Guarantor with and into an Issuer or another Guarantor that is the surviving Person
in such merger, amalgamation or consolidation, or upon the liquidation or dissolution of such Guarantor, such Guarantor will be relieved of any obligations under its Note Guarantee and all of its other obligations under this Indenture. 

Any Guarantor not released from its obligations under its Note Guarantee as provided in this Section 10.05 will remain liable for the
full amount of principal of and interest, and premium, if any, on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article 10. 

ARTICLE 11 
 SATISFACTION
AND DISCHARGE 
 Section 11.01 Satisfaction and Discharge. 

This 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 Issuers, 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 sending
of a notice of redemption or otherwise or will become due and payable within one year and the Issuers 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 of cash in U.S. dollars and non-callable Government Securities, in 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, if any, to the date of Stated Maturity or redemption; 

(2) in the case of clause (1)(b) above, 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 deposit will not result in a breach or violation of, or constitute a default under, any other instrument to which any
Issuer or any Guarantor is a party or by which any Issuer or any Guarantor is bound; 

  
 84 

 (3) the Issuers or any Guarantor has paid or caused to be paid all sums payable
by it under this Indenture; and 
 (4) the Issuers have delivered irrevocable instructions to the Trustee under this
Indenture to apply the deposited money toward the payment of the Notes at Stated Maturity or on the Redemption Date, as the case may be. 
 In
addition, the Issuers must deliver (a) an Officers’ Certificate stating that all conditions precedent set forth in clauses (1) through (4) above have been satisfied, and (b) an Opinion of Counsel to the Trustee (which
Opinion of Counsel may be subject to customary assumptions and qualifications), stating that all conditions precedent to satisfaction and discharge set forth in Section 11.01(2) and (4) have been satisfied; provided that the Opinion
of Counsel with respect to 11.01(2) above may be to the knowledge of such counsel.  
 Notwithstanding the satisfaction and discharge
of this Indenture, if money has been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section 11.01, the provisions of Sections 11.02 and 8.06 hereof will survive. In addition, nothing in this
Section 11.01 will be deemed to discharge those provisions of Section 7.07 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture. 

Section 11.02 Application of Trust Money. 

Subject to the provisions of Section 8.06 hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof shall be held
in trust and applied by it, in accordance with the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including either Issuer acting as Paying Agent) as the Trustee may determine, to the Persons
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 11.01 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 Issuers’ and any Guarantor’s obligations under this Indenture
and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 11.01 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 11.01;
provided that if the Issuers have made any payment of principal of, premium, if any, or interest on any Notes because of the reinstatement of their obligations, the Issuers 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.

[Form of Reverse of Note] 
 6%
Senior Notes due 2024 
 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless
otherwise indicated. 
 (1) INTEREST. Holly Energy Partners, L.P., a Delaware limited
partnership (“Holly Energy Partners”), and Holly Energy Finance Corp., a Delaware corporation (“Finance Corp.” and, together with Holly Energy Partners, the “Issuers”), promise to pay interest on the principal amount of
this Note at 6% per annum from July 19, 2016 until maturity. The Issuers will pay interest semi-annually in arrears on February 1 and August 1 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 February 1, 2017. Interest will be computed on the basis of a 360-day year of twelve 30-day months. 

(2) METHOD OF PAYMENT. The Issuers will pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders of Notes at the close of business on the January 15 or July 15 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or
before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. The Notes will be payable as to principal, premium and interest at the office or agency of the Issuers maintained for
such purpose within or without the City and State of New York, or, at the option of the Issuers, payment of interest may be made by check mailed to the Holders at their addresses set forth in the register of Holders; provided that payment by
wire transfer of immediately available funds will be required with respect to principal of and interest and premium on, all Global Notes and all other Notes the Holders of which will have provided wire transfer instructions to the Issuers or the
Paying Agent to an account in the United States. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. 

(3) PAYING AGENT AND REGISTRAR. Initially, U.S. Bank
National Association, the Trustee under the Indenture, will act as Paying Agent and Registrar. The Issuers may change any Paying Agent or Registrar without notice to any Holder. Holly Energy Partners or any of its Subsidiaries may act in any such
capacity. 
 (4) INDENTURE. The Issuers issued the Notes under an Indenture dated as of
July 19, 2016 (the “Indenture”) among the Issuers, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture. The Notes are subject to all such terms, and Holders are referred to the 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 Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured obligations of the
Issuers. The Indenture does not limit the aggregate principal amount of Notes that may be issued thereunder.  

  
 5 

 (5) OPTIONAL REDEMPTION. 

(a) Except pursuant to paragraphs (b), (c) and (d) of this Section 5, the Notes will not be redeemable at the Issuers’
option prior to August 1, 2019. On or after August 1, 2019, the Issuers may redeem all or a part of the Notes, upon prior notice in accordance with Section 3.02 of the Indenture, at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest on the Notes redeemed to, but excluding, the applicable Redemption Date, if redeemed during the twelve-month period beginning on August 1 of each year indicated below, subject
to the rights of Holders of Notes on the relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date: 
  

					
	 Year
	  	Percentage	 
	 2019
	  	 	104.500	% 
	 2020
	  	 	103.000	% 
	 2021
	  	 	101.500	% 
	 2022 and thereafter
	  	 	100.000	% 

 Unless the Issuers default in the payment of the redemption price, interest will cease to accrue on the Notes
or portions thereof called for redemption on the applicable Redemption Date. 
 (b) Notwithstanding the provisions of subparagraph
(a) of this Paragraph 5, at any time prior to August 1, 2019, the Issuers may on any one or more occasions redeem, upon prior notice in accordance with Section 3.02 of the Indenture, up to 35% of the aggregate principal amount of
Notes (including any Additional Notes) issued under this Indenture at a redemption price of 106% of the principal amount thereof, plus accrued and unpaid interest to, but excluding, the Redemption Date (subject to the right of Holders of Notes on
the relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date), with an amount of cash not greater than the net cash proceeds of one or more Equity Offerings by Holly Energy Partners;
provided that at least 65% of the aggregate principal amount of Notes (including any Additional Notes) issued under this Indenture (excluding Notes held by Holly Energy Partners and its Subsidiaries) remains outstanding immediately after the
occurrence of such redemption; and the redemption occurs within 180 days of the date of the closing of such Equity Offering. 
 (c)
Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior to August 1, 2019, the Issuers may also redeem all or a part of the Notes, upon prior notice in accordance with Section 3.02 of the Indenture,
at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest to, but excluding, the Redemption Date, subject to the rights of Holders on the relevant record date to
receive interest due on an interest payment date that is on prior to the Redemption Date. 
 (d) The Issuers may also redeem the Notes as
provided in Section 4.15(d) of the Indenture, on the terms and subject to the conditions set forth therein. 
 For purposes of this
Paragraph 5, “Applicable Premium” means, with respect to any Note at the time of determination, the greater of: (1) 1.00% of the principal amount of the Note; or (2) the excess of: (a) the present value at such time
of (i) the redemption price of the Note at August 1, 2019 (such redemption price being set forth in the table appearing in Section 3.07 of the Indenture) plus (ii) all required interest payments due on the Note through
August 1, 2019 (excluding accrued but unpaid interest to the Redemption Date), computed using a discount rate equal to the Treasury Rate as of such Redemption Date plus 50 basis points; over (b) the principal amount of the Note, if
greater. “Treasury Rate” means, as of the time of computation, the yield to maturity as of such time of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve
Statistical Release H.15 (519) that has become publicly available at least two Business Days prior to the Redemption Date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most
nearly equal to the period from the Redemption Date to August 1, 2019; provided, however, that if the period from the Redemption Date to August 1, 2019, is less than one year, the weekly average yield on actually traded United
States Treasury securities adjusted to a constant maturity of one year will be used.

 (6) MANDATORY REDEMPTION. 

The Issuers are not required to make mandatory redemption or sinking fund payments with respect to the Notes. The Issuers may acquire the Notes
by means other than a redemption, whether pursuant to a tender offer, open market purchase or otherwise, so long as the acquisition does not violate the terms of the Indenture. 

(7) REPURCHASE AT THE OPTION OF
HOLDER. 
 (a) If there is a Change of Control, the Issuers will be required to make an offer (a “Change of
Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of each Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount
thereof plus accrued and unpaid interest 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 that is on or prior to the date of purchase (the
“Change of Control Payment”). Within 30 days following any Change of Control, the Issuers will send a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. 

(b) If the Issuers or a Restricted Subsidiary of Holly Energy Partners consummates any Asset Sales, within five days of each date on
which the aggregate amount of Excess Proceeds exceeds $30.0 million, the Issuers will commence an offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set
forth in Section 4.10 of the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (an “Asset Sale Offer”) to purchase the maximum principal amount of Notes and such other pari passu
Indebtedness that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount plus accrued and unpaid interest to the date of purchase, in accordance with the procedures set forth in
Section 3.09 of the Indenture. If any Excess Proceeds remain after consummation of an Asset Sale Offer, Holly Energy Partners (or any Restricted Subsidiary) may use such Excess Proceeds for any purpose not otherwise prohibited by the 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 shall select the Notes and the representative of such other pari passu
Indebtedness will select such other pari passu Indebtedness to be purchased on a pro rata basis. Holders of Notes that are the subject of an Asset Sale Offer will receive an offer to purchase from the Issuers prior to any related
purchase date and may elect to have such Notes purchased by completing the form entitled “Option of Holder to Elect Purchase” attached to the Notes. 

(8) NOTICE OF REDEMPTION. Notice of redemption will be mailed (or sent
electronically in the case of notices to DTC), at least 15 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 given 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 Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of
$1,000 and in excess of $2,000, unless all of the Notes held by a Holder are to be redeemed. Notice of any redemption of the Notes (including upon an Equity Offering or in connection with a transaction (or series of related transactions) that
constitute a Change of Control) may, at the Issuers’ discretion, be given prior to the completion thereof and be subject to one or more conditions precedent, including, but not limited to, completed of the related Equity Offering or Change of
Control. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuers’ discretion, the Redemption 

  
 7 

 
Date may be delayed until such time (including more than 60 days after the date the notice of redemption was delivered) as any or all such conditions shall be satisfied, or such redemption may
not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date so delayed, or such notice may be rescinded at any time in the Issuers’
discretion if in the good faith judgment of the Issuers any or all of such conditions will not be satisfied 
 (9)
DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of
Notes may be registered and Notes may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuers may require a Holder
to pay any transfer tax or similar governmental charge required by law or permitted by the Indenture. The Issuers 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 Issuers 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. 
 (10) PERSONS DEEMED OWNERS. The registered
Holder of a Note may be treated as its owner for all purposes, and only such Holders have rights under the Indenture. 
 (11)
AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture or the Notes or the Note Guarantees may be amended or supplemented with the consent of
the Holders of a majority in aggregate principal amount of the then outstanding Notes including Additional Notes, if any, and any existing Default or Event of Default or compliance with any provision of the 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 including Additional Notes, if any. Without the consent of any Holder of a Note, the 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 Issuers’ or a
Guarantor’s obligations to Holders of the Notes and Note Guarantees in the case of a merger or consolidation or sale of all or substantially all of the Issuers’ or such Guarantor’s assets, as applicable, to make any change that would

of the Indenture under the TIA, to conform the text of the Indenture, the Notes or the Note Guarantees to any provision of the “Description of Notes” section of the Issuers’ Offering Memorandum to the extent that such provision was
intended to be a verbatim recitation of a provision of the Indenture, the Notes or Note Guarantee, to provide for the issuance of Additional Notes in accordance with the limitations set forth in the Indenture as of the Issue Date, to allow any
Guarantor to execute a supplemental indenture and/or a notation of a Note Guarantee with respect to the Notes or to reflect the release of a Note Guarantee in accordance with this Indenture, to secure the Notes and/or the Note Guarantees, to comply
with the rules of any applicable securities depository or to provide for the reorganization of Holly Energy Partners in any other form or entity, in accordance with Section 5.01(b) of the Indenture. 

(12) DEFAULTS AND REMEDIES. Events of Default include: (i) default for

if any, on, such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on the date of such default (a “Payment Default”) or (B) results in the acceleration of such Indebtedness prior to its
express maturity, in each case subject to a minimum threshold and cure period; (vii) certain final judgments for the payment of money that remain undischarged for a period of 60 days; (viii) certain events of bankruptcy or insolvency with
respect to the Issuers or any of Holly Energy Partners’ Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary; and (ix) except as
permitted by the 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 its behalf denies or disaffirms its
obligations under such Guarantor’s Note Guarantee. 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, with respect to Finance Corp., Holly Energy Partners or any Restricted Subsidiary of Holly Energy
Partners that is a Significant Subsidiary or any group of Restricted Subsidiaries of Holly Energy Partners that, taken together, would constitute a Significant Subsidiary, all outstanding Notes will become due and payable immediately without further

exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default or Event of Default relating to
the payment of principal, interest, or premium, if any. 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 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 Issuers and the Guarantors
are required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Issuers and the Guarantors are 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. 
 (13) TRUSTEE DEALINGS WITH
THE ISSUERS. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuers or their Affiliates, and may otherwise deal with the
Issuers or their Affiliates, as if it were not the Trustee. 
 (14) NO RECOURSE AGAINST
OTHERS. A director, officer, partner, member, employee, incorporator, manager or unit holder or other owner of Equity Interest of the Issuers, the General Partner or any Guarantor, as such, will not have any
liability for any obligations of the Issuers or the Guarantors under the Notes, the Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of Notes 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 and the Note Guarantees.

Trustee or an authenticating agent.

 (xxii) The public accountants whose reports appear or are incorporated by reference in the Offering
Memorandum are independent public accountants with respect to the Partnership within the meaning of Rule 101 of the Code of Professional Conduct of the American Institute of Certified Public Accountants and as required by the Public Company
Accounting Oversight Board (the “PCAOB”). The historical financial statements (including the notes thereto) included or incorporated by reference in the Offering Memorandum present fairly in all material respects the consolidated
combined financial position, results of operations, cash flows and changes in partner’s equity of the entities to which they relate at the respective dates and for the respective periods indicated. All such financial statements have been
prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) applied on a consistent basis throughout the periods presented (except as disclosed therein) and in compliance with Regulation S-X (“Regulation S-X”) under the Exchange Act, except that the interim financial statements do not include full footnote disclosure. The financial information
set forth under the captions “Summary – Summary Historical Financial and Operating Data” and “Selected Financial Data” included in or incorporated by reference in the Offering Memorandum has been prepared on a basis
consistent with that of the audited and unaudited financial statements from which it is derived.  
 (xxiii) Since the
date as of which information is given in the Offering Memorandum, except as set forth or contemplated in the Offering Memorandum, (A) neither Issuer nor any Subsidiary has (1) incurred any liabilities or obligations, direct or contingent,
that, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect, or (2) entered into any material transaction not in the ordinary course of business and (B) except for the Partnership’s regular
distribution of $0.575 per unit, announced on April 22, 2016 and payable on May 13, 2016 to holders of record of the Partnership’s common units on May 2, 2016, there has been no dividend or distribution of any kind declared, paid
or made by the Partnership on any of its equity interests. The interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Offering Memorandum fairly presents the information called for in all material
respects and have been prepared in accordance with the Commission’s rules and guidelines applicable thereto. 
 (xxiv)
Except as set forth in the Offering Memorandum, there are no legal or governmental proceedings pending to which either Issuer or any Subsidiary is a party or of which any property of either Issuer or any Subsidiary is the subject which, if
determined adversely to such Issuer or Subsidiary, as the case may be, individually or in the aggregate, would reasonably be expected to have a Material Adverse Effect and, to the best knowledge of the Issuers and the Guarantors, no such proceedings
are threatened. 

  
 11 

 (xxv) No labor dispute with the employees of the Issuers or any Subsidiary exists
or, to the knowledge of the Issuers and the Guarantors, is imminent and the Issuers are not aware of any existing or imminent labor disturbance by the employees of any of their or the Subsidiaries’ principal suppliers, contractors or customers,
in each case, that is reasonably likely to result in a Material Adverse Effect. 
 (xxvi) Except as disclosed in the
Offering Memorandum, the Partnership and its Subsidiaries (i) are in compliance with any and all applicable foreign, federal, state and local laws and regulations relating to the protection of human health and safety and the environment or
imposing liability or standards of conduct, including the transport of, concerning any Hazardous Material (as defined below) (“Environmental Laws”), (ii) have received, and maintain in full force and effect, all Permits (as
defined below) required of them under applicable Environmental Laws to conduct their respective businesses, (iii) are in compliance with the terms and conditions of any such Permits, and (iv) to the knowledge of the Partnership, do not
have any liability in connection with either noncompliance with Environmental Laws or with the release into the environment of any Hazardous Materials, and (v) are not subject to any pending or, to the knowledge of the Partnership, threatened
claim or other legal proceeding under any Environmental Laws, except where such noncompliance with the Environmental Laws, failure to receive required Permits, failure to comply with the terms and conditions of such Permits or liability in
connection with such noncompliance, releases, claims or legal proceedings would not reasonably be expected to, individually or in the aggregate, have a Material Adverse Effect. The term “Hazardous Material” means (A) any
“hazardous substance” as defined in the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, (B) any “hazardous waste” as defined in the Resource Conservation and Recovery Act, as
amended, (C) any petroleum or petroleum product, (D) any polychlorinated biphenyl and (E) any pollutant or contaminant or hazardous, dangerous or toxic chemical, material, waste or substance regulated under or within the meaning of
any other Environmental Law. 
 (xxvii) In the ordinary course of its business, the Partnership periodically reviews
the effect of Environmental Laws on the business, operations and properties of the Partnership and its Subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or
operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws, or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the
basis of such review, the Partnership has concluded that such associated costs and liabilities as of the date hereof would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. 

(xxviii) Each of the Issuers and the Subsidiaries has such permits, consents, licenses, franchises, certificates and
authorizations of governmental or regulatory authority (“Permits”) as are necessary to own its properties and to conduct its business in the manner described in the Offering Memorandum, subject to such qualifications as may be set
forth in the Offering Memorandum (exclusive of any amendment or supplement thereto) and except for such Permits which, if not obtained, would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; each of
the Issuers and the Subsidiaries has fulfilled and performed all its material obligations with respect to such Permits which are due to have been fulfilled and performed and no event has occurred which allows, or after notice or lapse of time would
allow, revocation or termination thereof or results in any impairment of the rights of the holder of any such Permit, except for such revocations, terminations and impairments that would not, individually or in the aggregate, reasonably be expected
to have a Material Adverse Effect, subject in each case to such qualifications as may be set forth in the Offering Memorandum  

  
 12 

 
(exclusive of any amendment or supplement thereto); and except as described in the Offering Memorandum, none of the Permits contains any restriction that is materially burdensome to the
Partnership and the Subsidiaries, taken as a whole. 
 (xxix) The Operating Partnership and the other Subsidiaries
have such consents, easements, rights-of-way, permits or licenses from each person (collectively, “rights-of-way”) as are necessary to conduct its business in the manner described, and subject to the limitations contained, in the
Offering Memorandum, except for (A) qualifications, reservations and encumbrances which would not reasonably be expected to have a Material Adverse Effect upon the ability of the Partnership and its Subsidiaries, taken as a whole, to conduct
their businesses in all material respects as currently conducted and as contemplated by the Offering Memorandum to be conducted and (B) such rights-of-way that, if not obtained, would not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect upon the ability of the Partnership and its Subsidiaries, taken as a whole, to conduct their businesses in all material respects as currently conducted and as contemplated by the Offering Memorandum to be
conducted; other than as set forth, and subject to the limitations contained, in the Offering Memorandum, each of the Partnership and its Subsidiaries has fulfilled and performed all its material obligations with respect to such rights-of-way and no
event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or would result in any impairment of the rights of the holder of any such rights-of-way, except for such revocations, terminations and
impairments that would not have a Material Adverse Effect upon the ability of the Partnership and its Subsidiaries, taken as a whole, to conduct their businesses in all material respects as currently conducted and as contemplated by the Offering
Memorandum to be conducted; and, except as described in the Offering Memorandum, none of such rights-of-way contains any restriction that is materially burdensome to the Partnership and its Subsidiaries, taken as a whole. 

(xxx) The Issuers and the Subsidiaries have filed (or have obtained extensions with respect to) all federal, state and foreign
income and franchise tax returns required to be filed through the date hereof, which returns are complete and correct in all material respects, and have timely paid all taxes shown to be due pursuant to such returns, other than those (A) which,
if not paid, would not reasonably be expected to have a Material Adverse Effect or (B) which are being contested in good faith and for which adequate reserves have been established in accordance with generally accepted accounting principles.

 (xxxi) There is and has been no failure on the part of the Partnership or any member, officer or director of the
Partnership, the General Partner or GP L.L.C., in their capacities as such, to comply in all material respects with any provision of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith (the
“Sarbanes-Oxley Act”), including Section 402 relating to loans and Sections 302 and 906 relating to certifications. 

(xxxii) None of the Partnership or any of its Subsidiaries nor, to the knowledge of the Partnership, any member,
officer, agent, employee or affiliate of the Partnership or any of its Subsidiaries is aware of or has taken any action, directly or indirectly, that would result in a violation or a sanction for violation by such persons of (i) the Foreign
Corrupt Practices Act of 1977, as amended, or the rules or regulations thereunder (the “FCPA”), including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance
of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the
FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA, (ii)  

  
 13 

 
the U.K. Bribery Act 2010, as amended, or the rules or regulations thereunder (together with the FCPA, the “Anti-Bribery Laws”) or (iii) any similar law of any other
relevant jurisdiction or the rules or regulations thereunder; the Partnership, the Subsidiaries and, to the knowledge of the Partnership, their affiliates, have conducted their businesses in compliance with the Anti-Bribery Laws and similar laws of
any other relevant jurisdiction and the rules and regulations thereunder, and have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith; and no
part of the proceeds from the sale of the Securities will be used, directly or indirectly, in violation of the Anti-Bribery Laws or any similar law of any other relevant jurisdiction, or the rules or regulations thereunder.  

(xxxiii) The operations of the Partnership and its Subsidiaries are and have been conducted at all times in compliance
with applicable financial recordkeeping and reporting requirements and the money laundering statutes and the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any
governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Partnership or any of its
Subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Partnership, threatened. 

(xxxiv) Neither the Partnership nor any of its Subsidiaries nor, to the knowledge of the Partnership, any member,
officer, agent, employee or affiliate of the Partnership or any of its Subsidiaries (i) is, or is controlled or 50% or more owned by or is acting on behalf of, an individual or entity that is currently subject to any sanctions administered or
enforced by the United States (including any administered or enforced by the Office of Foreign Assets Control of the U.S. Treasury Department, the U.S. Department of State, or the Bureau of Industry and Security of the U.S. Department of Commerce)
or other relevant sanctions authority (collectively, “Sanctions” and such persons, “Sanctioned Persons”), (ii) is located, organized or resident in a country or territory that is, or whose government is, the
subject of Sanctions that broadly prohibit dealings with that country or territory (collectively, “Sanctioned Countries” and each a “Sanctioned Country”) or (iii) will directly or indirectly, use the proceeds
of the offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity for the purpose of financing the activities of any Sanctioned Person, or in any other manner that would
result in a violation of any Sanctions by, or could result in the imposition of Sanctions against, any individual or entity (including any individual or entity participating in the offering, whether as underwriter, advisor, investor or
otherwise). 
 (xxxv) Except as has been disclosed to the Initial Purchasers or is not material to the analysis under
any Sanctions, neither the Partnership nor any of the Subsidiaries has engaged in any dealings or transactions with or for the benefit of a Sanctioned Person, or with or in a Sanctioned Country, in the preceding 3 years, nor does the Partnership or
any of the Subsidiaries have any plans to increase its dealings or transactions with or for the benefit of Sanctioned Persons, or with or in Sanctioned Countries. 

(xxxvi) The statements set forth in the Offering Memorandum under the caption “Description of Notes”, insofar as they
purport to constitute a summary of the terms of the Notes, under the caption “Certain Material U.S. Federal Income Tax Considerations”, and under the caption “Plan of Distribution”, insofar as they purport to describe the
provisions of the laws and documents referred to therein, are accurate, complete and fair; provided, however, that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with
information furnished in writing to the Partnership by or on behalf of any Initial Purchaser through the Representative expressly for use therein. 

  
 14 

 (xxxvii) None of the Issuers or the Guarantors is, nor, after giving effect to
the Offering and the application of the proceeds thereof, will be, an “investment company” or a company “controlled by” an “investment company” as such terms are defined in the Investment Company Act of 1940, as
amended. 
 (xxxviii) The Partnership and the Subsidiaries maintain a system of internal control over financial reporting (as
such term is defined in Rule 13(a)-15(f) under the Exchange Act) that complies with the requirements of the Exchange Act and has been designed by the Partnership’s principal executive officer and principal financial officer, or under their
supervision, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and that the interactive data
in eXtensible Business Reporting Language included or incorporated by reference in the Offering Memorandum fairly presents the information called for in all material respects and is prepared in accordance with the Commission’s rules and
guidelines applicable thereto. The Partnership’s internal control over financial reporting is effective to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external
purposes in accordance with generally accepted accounting principles and the Partnership is not aware of any material weaknesses in its internal controls over financial reporting. 

(xxxix) Since the date of the latest audited financial statements included or incorporated by reference in the Offering
Memorandum, there has been no change in the Partnership’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Partnership’s internal control over financial reporting.

 (xl) The Partnership maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the
Exchange Act) that comply with the requirements of the Exchange Act; such disclosure controls and procedures have been designed to ensure that material information relating to the Partnership and the Subsidiaries is made known to the
Partnership’s principal executive officer and principal financial officer by others within those entities; and such disclosure controls and procedures are effective. 

(xli) The Issuers and the Subsidiaries maintain, or are entitled to the benefits of, insurance in such amounts and covering
such risks as the Issuers reasonably believe is adequate for the conduct of the business of the Partnership and the Subsidiaries. Neither the Partnership nor any of the Subsidiaries has received notice from any insurer or agent of such insurer that
substantial capital improvements or other expenditures will have to be made in order to continue such insurance, and all such insurance is outstanding and duly in force on the date hereof and will be outstanding and duly in force at Closing Date.

 (xlii) The Partnership is a partnership for U.S. federal income tax purposes. 

(xliii) The assumptions used in the preparation of the adjusted financial information included in the Offering Memorandum
(including “EBITDA” and “distributable cash flow”) are reasonable, and the adjustments used therein are appropriate to give effect to the transactions or circumstances referred to therein. 

  
 15 

 (xliv) No Subsidiary is currently prohibited, directly or indirectly, from paying
any dividends to the Partnership, from making any other distribution on such Subsidiary’s capital stock (or other ownership interests, as the case may be), from repaying to the Partnership any loans or advances to such Subsidiary from the
Partnership or from transferring any of such Subsidiary’s property or assets to the Partnership or any other Subsidiary, except as described in or contemplated in the Offering Memorandum. 

(xlv) Except as described in the section entitled “Plan of Distribution” in the Offering Memorandum, there are no
contracts, agreements or understandings between either Issuer or any Subsidiary and any other person other than the Initial Purchasers pursuant to this Agreement that would give rise to a valid claim against either Issuer, any Subsidiary or any of
the Initial Purchasers for a brokerage commission, finder’s fee or like payment in connection with the issuance, purchase and sale of the Securities. 

(xlvi) None of the Issuers, the Guarantors or any of their affiliates (as defined in Rule 501(b) of Regulation D under the Act)
has, directly or through any person acting on its or their behalf (other than any Initial Purchaser, as to which no representation is made), (A) taken, directly or indirectly, any action designed to, or that might reasonably be expected to,
cause or result in stabilization or manipulation of the price of any security of any Issuer to facilitate the sale or resale of the Securities, (B) sold, bid for, purchased or paid any person any compensation for soliciting purchases of the
Securities in a manner that would require registration of the Securities under the Act or paid or agreed to pay to any person any compensation for soliciting another to purchase any other securities of any Issuer in a manner that would require
registration of the Securities under the Act, (C) sold, offered for sale, contracted to sell, pledged, solicited offers to buy or otherwise disposed of or negotiated in respect of any security (as defined in the Act) that is currently or will
be integrated with the sale of the Securities in a manner that would require the registration of the Securities under the Act or (D) engaged in any directed selling effort (as defined by Regulation S) with respect to the Securities, and each of
them has complied with the offering restrictions requirement of Regulation S. 
 (xlvii) No form of general solicitation or
general advertising (prohibited by the Act in connection with offers or sales such as the Exempt Resales) was used by the Issuers or any person acting on its behalf (other than any Initial Purchaser, as to which no representation is made) in
connection with the offer and sale of any of the Securities or in connection with Exempt Resales, including, but not limited to, articles, notices or other communications published in any newspaper, magazine or similar medium or broadcast over
television or radio or the Internet, or any seminar or meeting whose attendees have been invited by any general solicitation or general advertising within the meaning of Regulation D under the Act. Neither the Issuers nor any of their
affiliates has entered into, or will enter into, any contractual arrangement with respect to the distribution of the Securities except for this Agreement. 

(xlviii) Neither the issuance, sale and delivery of the Securities nor the application of the proceeds thereof by the Issuers
as described in the Offering Memorandum will violate Regulation T, U or X of the Board of Governors of the Federal Reserve System or any other regulation of such Board of Governors. 

Each certificate signed by any officer of either Issuer or any Guarantor and delivered to the Initial Purchasers or counsel for the Initial
Purchasers pursuant to, or in connection with, this Agreement shall be deemed to be a representation and warranty by the Issuers and Guarantors to the Initial Purchasers as to the matters covered by such certificate. 

  
 16 

 The Issuers acknowledge that the Initial Purchasers and, for purposes of the opinions to be
delivered to the Initial Purchasers pursuant to Section 8 of this Agreement, counsel to the Partnership and counsel to the Initial Purchasers will rely upon the accuracy and truth of the foregoing representations and the Issuers hereby consent
to such reliance. 
 (b) Each Initial Purchaser represents that it is a QIB and acknowledges that it is purchasing the Securities pursuant
to a private sale exemption from registration under the Act, and that the Securities have not been registered under the Act and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons except pursuant
to an exemption from the registration requirements of the Act. Each Initial Purchaser, severally and not jointly, represents, warrants and covenants to the Issuers and Guarantors that: 

(i) Neither it, nor any person acting on its behalf, has or will solicit offers for, or offer or sell, the Securities by any
form of general solicitation or general advertising (as those terms are used in Regulation D under the Act) or in any manner involving a public offering within the meaning of Section 4(2) of the Act, and it has and will solicit offers for the
Securities only from, and will offer and sell the Securities only to, (1) persons whom such Initial Purchaser reasonably believes to be QIBs or, if any such person is buying for one or more institutional accounts for which such person is acting
as fiduciary or agent, only when such person has represented to such Initial Purchaser that each such account is a QIB to whom notice has been given that such sale or delivery is being made in reliance on Rule 144A, and, in each case, in reliance on
the exemption from the registration requirements of the Act pursuant to Rule 144A, or (2) persons other than U.S. persons outside the United States in reliance on, and in compliance with, the exemption from the registration requirements of the
Act provided by Regulation S. 
 (ii) With respect to offers and sales outside the United States, such Initial Purchaser
has offered the Securities and will offer and sell the Securities (1) as part of its distribution at any time and (2) otherwise until 40 days after the later of the commencement of the offering of the Securities and the Closing Date, only
in accordance with Rule 903 of Regulation S or another exemption from the registration requirements of the Act. Accordingly, neither such Initial Purchasers nor any person acting on their behalf has engaged or will engage in any directed
selling efforts (within the meaning of Regulation S) with respect to the Securities, and any such persons have complied and will comply with the offering restrictions requirements of Regulation S. Terms used in this
Section 5(b)(ii) have the meanings given to them by Regulation S. 
 Each Initial Purchaser severally agrees that, at or prior
to confirmation of a sale of Securities pursuant to Regulation S it will have sent to each distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Securities from it or through it during the restricted
period a confirmation or notice to substantially the following effect: 
 “The Securities covered hereby have not been
registered under the United States Securities Act of 1933, as amended (the “Securities Act”), and may not be offered or sold within the United States or to or for the account or benefit of, U.S. persons (i) as part of their
distribution at any time and (ii) otherwise until forty days after the later of the date upon which the offering of the Securities commenced and the date of closing, except in either case in accordance with Regulation S or Rule 144A under the
Securities Act. Terms used above have the meaning given to them by Regulation S.” 

  
 17 

 The Initial Purchasers understand that the Issuers and Guarantors and, for purposes of the
opinions to be delivered to them pursuant to Section 8 hereof, counsel to the Issuers and Guarantors and counsel to the Initial Purchasers will rely upon the accuracy and truth of the foregoing representations, and each Initial Purchaser hereby
consents to such reliance. 
 6. Indemnification. (a) The Issuers and Guarantors, jointly and severally, agree to indemnify and
hold harmless the Initial Purchasers, each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, the agents, employees, officers and directors of any
Initial Purchaser and the agents, employees, officers and directors of any such controlling person from and against any and all losses, liabilities, claims, damages and expenses whatsoever (including, but not limited, to reasonable attorneys’
fees and any and all reasonable expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all reasonable amounts paid in settlement of any claim or
litigation) (collectively, “Losses”) to which they or any of them may become subject under the Act, the Exchange Act or otherwise insofar as such Losses (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 Pricing Disclosure Package, any Issuer Written Communication (including, but not limited to, any electronic roadshow), the Final Offering Memorandum, or in any amendment or
supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading;
provided that none of the Issuers and Guarantors will be liable in any such case to the extent, but only to the extent, that any such Loss arises out of or is based upon any such untrue statement or alleged untrue statement or omission or
alleged omission relating to an Initial Purchaser made therein in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of such Initial Purchaser through the Representative expressly for use therein.
This indemnity agreement will be in addition to any liability that the Issuers and Guarantors may otherwise have, including, but not limited to, liability under this Agreement. 

(b) Each Initial Purchaser, severally and not jointly, agrees to indemnify and hold harmless the Issuers and Guarantors, and each person, if
any, who controls any of the Issuers and Guarantors within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, the agents, employees, officers and directors of any of the Issuers and Guarantors and of any such
controlling person from and against any and all Losses to which they or any of them may become subject under the Act, the Exchange Act or otherwise insofar as such Losses (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 Pricing Disclosure Package or the Final Offering Memorandum, or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that any such Loss arises out of or is based
upon any untrue statement or alleged untrue statement or omission or alleged omission relating to such Initial Purchaser made therein in reliance upon and in conformity with information furnished in writing to the Partnership by or on behalf of such
Initial Purchaser through the Representative expressly for use therein. The Issuers and Guarantors and the Initial Purchasers acknowledge that the information described in Section 9 is the only information furnished in writing by the Initial
Purchasers to the Issuers expressly for use in the Preliminary Offering Memorandum or the Final Offering Memorandum. 
 (c) Promptly
after receipt by an indemnified party under subsection 6(a) or 6(b) above of notice of the commencement of any action, suit or proceeding (collectively, an “action”), such indemnified party shall, if a claim in respect
thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the commencement of such action (but the failure so to notify the indemnifying party will not
relieve it from  

  
 18 

 
liability under paragraph (a) or (b) above unless and to the extent it has been prejudiced in any material respect by such failure). In case any such action is brought against any
indemnified party, and it notifies an indemnifying party of the commencement of such action, the indemnifying party will be entitled to participate in such action, and to the extent it may elect by written notice delivered to the indemnified party
promptly after receiving the aforesaid notice from such indemnified party, to assume the defense of such action with counsel satisfactory to such indemnified party. Notwithstanding the foregoing, the indemnified party or parties shall have the right
to employ its or their own counsel in any such action, but the reasonable fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless (i) the employment of such counsel shall have been authorized in
writing by the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to take charge of the defense of such action within a reasonable time after notice of commencement
of the action, or (iii) the named parties to such action (including any impleaded parties) include such indemnified party and the indemnifying parties (or such indemnifying parties have assumed the defense of such action), and such indemnified
party or parties shall have reasonably concluded that there may be defenses available to it or them that are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not
have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such reasonable fees and expenses of counsel shall be borne by the indemnifying parties. In no event shall the indemnifying
parties be liable for the fees and expenses of more than one counsel (together with appropriate local counsel) at any time for all indemnified parties in connection with any one action or separate but substantially similar or related actions arising
in the same jurisdiction out of the same general allegations or circumstances. An indemnifying party shall not be liable for any settlement of any claim or action effected without its written consent, which consent may not be unreasonably withheld.
No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have
been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (y) does not include a
statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. 
 7.
Contribution. In order to provide for contribution in circumstances in which the indemnification provided for in Section 6 of this Agreement is for any reason held to be unavailable from the indemnifying party, or is insufficient
to hold harmless a party indemnified under Section 6 of this Agreement, each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such aggregate Losses (i) in such proportion as is
appropriate to reflect the relative benefits received by the Issuers and Guarantors, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities or (ii) if such allocation is not permitted by applicable
law, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Issuers and Guarantors, on the one hand, and the Initial Purchasers, on the other hand, in connection with the
statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. The relative benefits received by the Issuers and Guarantors, on the one hand, and the Initial Purchasers, on the other hand, shall be
deemed to be in the same proportion as (x) the total proceeds from the offering of Securities (net of discounts and commissions but before deducting expenses) received by the Issuers and Guarantors are to (y) the total discount and
commissions received by the Initial Purchasers. The relative fault of the Issuers and Guarantors, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by an Issuer or the Initial Purchasers and the parties’ relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission or alleged statement or omission. 

  
 19 

 The Issuers and Guarantors and the Initial Purchasers agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to above. Notwithstanding the provisions of
this Section 7, (i) in no case shall any Initial Purchaser be required to contribute any amount in excess of the amount by which the total discount and commissions applicable to the Securities purchased by such Initial Purchaser pursuant
to this Agreement exceeds the amount of any damages that such Initial Purchaser has otherwise been required to pay by reason of any untrue or alleged untrue statement or omission or alleged omission and (ii) 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 7, each person, if any, who
controls any Initial Purchaser within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act shall have the same rights to contribution as the Initial Purchasers, and each person, if any, who controls an Issuer or a
Guarantor within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act and each director, officer, employee and agent of an Issuer or a Guarantor shall have the same rights to contribution as the Issuers and
Guarantors. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action against such party in respect of which a claim for contribution may be made against another party or parties under this
Section 7, notify such party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may
have under this Section 7 or otherwise, but the failure so to notify the contributing party will not relieve it from liability under this Section 7 unless and to the extent it has been prejudiced in any material respect by such failure;
provided, however, that no additional notice shall be required with respect to any action for which notice has been given under Section 6 for purposes of indemnification. Anything in this section to the contrary notwithstanding,
no party shall be liable for contribution with respect to any action or claim settled without its written consent; provided, however, that such written consent was not unreasonably withheld. The contribution obligations of the Initial
Purchasers under this Section 7 are several in proportion to their respective purchase obligations with respect to the Securities and not joint. 

8. Conditions of Initial Purchasers’ Obligations. The obligations of the Initial Purchasers to purchase and pay for the
Securities, as provided for in this Agreement, shall be subject to satisfaction of the following conditions prior to or concurrently with such purchase: 

(a) All of the representations and warranties of the Issuers and the Guarantors contained in this Agreement shall be true and
correct on the date of this Agreement and on the Closing Date. The Issuers and the Guarantors shall have performed or complied with all of the agreements and covenants contained in this Agreement and required to be performed or complied with by them
at or prior to the Closing Date. The Initial Purchasers shall have received a certificate, dated the Closing Date, signed by the Chief Financial Officer and Treasurer of the Issuers, certifying as to the foregoing and to the effect in

form of Annex II(a) and Annex II(b) attached hereto; 
 (e) The Initial Purchasers shall have received on the
Closing Date an opinion dated the Closing Date of Latham & Watkins LLP, counsel to the Initial Purchasers, in form and substance satisfactory to the Representative. Such counsel shall have been furnished with such certificates and documents

warranties or conditions contained in this Agreement; 
 (f) The Issuers, the Guarantors and the Trustee shall have executed

 (g) On the date hereof, the
Initial Purchasers shall have received a “comfort letter” from the independent public accountants for the Partnership, dated the date of this Agreement, addressed to the Initial Purchasers and in form and substance satisfactory to the
Representative and counsel to the Initial Purchasers, covering the financial and accounting information in the Pricing Disclosure Package. In addition, the Initial Purchasers shall have received a
“bring-down comfort letter” from the independent public accountants for the Partnership, dated as of the Closing Date, addressed to the Initial Purchasers and in the form of the “comfort
letter” delivered on the date hereof, except that (i) it shall cover the financial and accounting information in the Final Offering Memorandum and any amendment or supplement thereto and (ii) procedures shall be brought down to a date
no more than 3 business days prior to the Closing Date, and otherwise in form and substance satisfactory to the Representative and counsel to the Initial Purchasers; 

(h) (i) Neither the Partnership nor any of its Subsidiaries shall have sustained since the date of the latest audited
financial statements included or incorporated by reference in the Final Offering Memorandum any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any court or

affairs, management, financial position, partners’ or stockholders’ equity or results of operations of the Partnership or any of its Subsidiaries, otherwise than as set forth or contemplated in the Final Offering Memorandum (exclusive of
any amendment or supplement thereto), the effect of which, in any such case described in clause (i) or (ii), is in your judgment so material and adverse as to make it impracticable or inadvisable to proceed with the offering or the delivery of
the Securities on the terms and in the manner contemplated in the Final Offering Memorandum (exclusive of any amendment or supplement thereto); 

(i) The Initial Purchasers shall have been furnished with written instructions for the application of the proceeds of the

Issuers at any time at or prior to the Closing Date, and such termination shall be without liability of any party to any other party, except to the extent set forth in Section 11(d) hereof. 

The documents required to be delivered by this Section 8 will be delivered at the office of counsel for the Initial Purchasers on the
Closing Date. 
 9. Initial Purchasers Information. The Issuers, the Guarantors and the Initial Purchasers severally
acknowledge that, for all purposes (including Sections 5(a)(i) and 6), that (a) the statements relating to stabilization transactions and penalty bids set forth in the ninth and tenth paragraphs, and the fourth and fifth sentences of the eighth
paragraph, each under “Plan of Distribution” in the Preliminary Offering Memorandum and the Final Offering Memorandum and (b) the name and contact information of the Initial Purchasers in the Preliminary Offering Memorandum and the
Final Offering Memorandum, constitute the only information furnished in writing by or on behalf of any Initial Purchaser expressly for use in the Pricing Disclosure Package or the Final Offering Memorandum. 

10. Survival of Representations and Agreements. All representations and warranties, covenants and agreements contained in this
Agreement, including the agreements contained in Sections 4(f) and 11(d), the indemnity agreements contained in Section 6 and the contribution agreements contained in Section 7, shall remain operative and in full force and effect
regardless of any investigation made by or on behalf of the Initial Purchasers or any controlling person thereof or by or on behalf of the Issuers, the Guarantors or any controlling person thereof, and shall survive delivery of and payment for the
Notes to and by the Initial Purchasers. The agreements contained in Sections 4(f), 6, 7, 9 and 11(d), and in Sections 13 through 19 shall survive the termination of this Agreement, including any termination pursuant to Sections 8, 11
or 12. 
 11. Effective Date of Agreement; Termination. (a) This Agreement shall become effective upon execution and
delivery of a counterpart hereof by each of the parties hereto. 
 (b) The Initial Purchasers shall have the right to terminate this
Agreement at any time prior to the Closing Date by notice to the Partnership from the Initial Purchasers, without liability (other than with respect to Sections 6 and 7) on the Initial Purchasers’ part to the Partnership or any affiliate
thereof if, on or prior to such date, (i) the Partnership shall have failed, refused or been unable to perform any agreement on its part to be performed under this Agreement when and as required; (ii) any other condition to the obligations
of the Initial Purchasers under this Agreement to be fulfilled by the Issuers and Guarantors pursuant to Section 8 is not fulfilled when and as required; (iii) trading in any securities of the Partnership shall be suspended or limited by
the Commission or the New York Stock Exchange, or trading in securities generally on the New York Stock Exchange, the NYSE MKT LLC or the Nasdaq Global Market shall have been suspended or materially limited, or minimum prices shall have been
established thereon by the Commission, or by such exchange or other regulatory body or governmental authority having jurisdiction; (iv) a general moratorium shall have been declared by either Federal or New York State authorities or a
material disruption in commercial banking or securities settlement or clearance services in the United States shall have occurred; (v) there is an outbreak or escalation of hostilities or national or international calamity in any case involving
the United States, on or after the date of this Agreement, or if there has been a declaration by the United States of a national 

  
 22 

 
emergency or war or other national or international calamity or crisis (economic, political, financial or otherwise) which affects the U.S. and international markets, making it, in the
Representative’s judgment, impracticable to proceed with the offering or delivery of the Securities on the terms and in the manner contemplated in the Pricing Disclosure Package; or (vi) there shall have been such a material adverse change
in general economic, political or financial conditions or the effect (or potential effect if the financial markets in the United States have not yet opened) of international conditions on the financial markets in the United States shall be such as,
in the Representative’s judgment, to make it inadvisable or impracticable to proceed with the offering or delivery of the Securities on the terms and in the manner contemplated in the Pricing Disclosure Package. 

(c) Any notice of termination pursuant to this Section 11 shall be given at the address specified in Section 13 below by telephone
or facsimile, confirmed in writing by letter. 
 (d) If this Agreement shall be terminated pursuant to Section 11(b)(i) or (ii), the
Issuers and Guarantors, jointly and severally, will reimburse the Initial Purchasers for all of their reasonable out-of-pocket expenses (including, without limitation,
the fees and expenses of the Initial Purchasers’ counsel) incurred in connection with this Agreement and the transactions contemplated hereby. 

12. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities
agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated severally to
take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Notes set forth opposite the names of all the remaining
Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Notes which the defaulting
Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Notes set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall
not be under any obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser or the
Partnership. In the event of a default by any Initial Purchaser as set forth in this Section 12, the Closing Date shall be postponed for such period, not exceeding seven Business Days, as the Representative shall determine in order that the
required changes in the Final Offering Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Partnership or any
nondefaulting Initial Purchaser for damages occasioned by its default hereunder. 
 13. Notices. In all dealings hereunder,
you shall act on behalf of each of the Initial Purchasers, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Initial Purchaser made or given jointly by Citigroup Global Markets
Inc., as the Representative, except as otherwise provided herein. All statements, requests, notices and agreements hereunder shall be in writing, and if to the Initial Purchasers shall be delivered or sent by mail or facsimile transmission to

other information that will allow the initial purchasers to properly identify their respective clients. 
 14. Parties.
This Agreement shall inure solely to the benefit of, and shall be binding upon, the Initial Purchasers, the Issuers and Guarantors and the other indemnified parties referred to in Sections 6 and 7, and their respective successors and assigns, and no
other person shall have or be construed to have any legal or equitable right, remedy or claim under or in respect of or by virtue of this Agreement or any provision herein contained. The term “successors and assigns” shall not include a
purchaser, in its capacity as such, of Securities from the Initial Purchasers. 
 15. CONSTRUCTION; GOVERNING LAW. THIS
AGREEMENT SHALL BE CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK (WITHOUT GIVING EFFECT TO ANY PROVISIONS THEREOF RELATING TO CONFLICTS OF LAW). 

16. Submission to Jurisdiction; Waiver of Jury Trial. No proceeding related to this Agreement or the transactions contemplated hereby
may be commenced, prosecuted or continued in any court other than the courts of competent subject matter jurisdiction of the State of New York located in the City and County of New York or in the United States District Court for the Southern
District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the Issuers and Guarantors hereby consent to the jurisdiction of such courts and personal service with respect thereto. The Issuers and Guarantors
hereby waive all right to trial by jury in any proceeding (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The Issuers and Guarantors agree that a final judgment in any such proceeding brought
in any such court shall be conclusive and binding upon the Issuers and Guarantors and may be enforced in any other courts in the jurisdiction of which the Issuers and Guarantors are or may be subject, by suit upon such judgment. 

17. Captions. The captions included in this Agreement are included solely for convenience of reference and are not to be

 18. Counterparts. This Agreement may be executed in various counterparts that together
shall constitute one and the same instrument. 
 19. No Fiduciary Relationship. The Issuers and Guarantors hereby acknowledge that
the Initial Purchasers are acting solely as initial purchasers in connection with the purchase and sale of the Securities. The Issuers and Guarantors further acknowledge that each of the Initial Purchasers is acting pursuant to a contractual
relationship created solely by this Agreement entered into on an arm’s length basis and in no event do the parties intend that any Initial Purchaser act or be responsible as a fiduciary to the Issuers and Guarantors, their management,
stockholders, creditors or any other person in connection with any activity that such Initial Purchaser may undertake or has undertaken in furtherance of the 

  
 24 

 
purchase and sale of the Securities, either before or after the date hereof. The Initial Purchasers hereby expressly disclaim any fiduciary or similar obligations to the Issuers and Guarantors,
either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Issuers and Guarantors hereby confirm their understanding and agreement to that effect. The Issuers and Guarantors and
each Initial Purchaser agree that they are each responsible for making their own independent judgments with respect to any such transactions, and that any opinions or views expressed by any Initial Purchaser to the Issuers and Guarantors regarding
such transactions, including but not limited to any opinions or views with respect to the price or market for the Securities, do not constitute advice or recommendations to the Issuers and Guarantors. The Issuers and Guarantors hereby waive and
release, to the fullest extent permitted by law, any claims that such Issuers and Guarantors may have against the Initial Purchasers with respect to any breach or alleged breach of any fiduciary or similar duty to the Issuers and Guarantors in
connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.
