and for the equal and ratable benefit of the Holders (as defined) of the 6.50% Senior Notes due 2020 (the “Notes”): 
 ARTICLE 1 
 DEFINITIONS AND INCORPORATION 

BY REFERENCE 

Section 1.01 Definitions. 
 “144A Global Note” means a Global Note substantially in the form of Exhibit A hereto bearing the 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 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 the possession, directly or indirectly, of the power to direct or
cause the direction of the management or policies of such Person, whether through the ownership of voting securities, by agreement or otherwise; provided that beneficial ownership of 10% or more of the Voting Stock of a Person will be deemed
to be control, provided, further, that any third Person which also beneficially owns 10% or more of the Voting Stock of a specified Person shall not be deemed to be an Affiliate of either the specified Person or the other Person merely
because of such common ownership in such specified Person. For purposes of this definition, the terms “controlling,” “controlled by” and “under common control with” have correlative meanings.

 “Agent” means any Registrar, co-registrar, Paying Agent or additional paying agent. 

“Applicable Premium” means, with respect to any Note on any redemption date, the greater of: 

(1) 1.00% of the principal amount of the Note; or 

  
 1 

 (2) the excess of: (a) the present value at such redemption date of
(i) the redemption price of the Note at March 1, 2016 (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 March 1, 2016
(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. 

“Applicable Procedures” means, with respect to any transfer or exchange of or for beneficial interests in any Global
Note, the rules and procedures of the Depositary, Euroclear and Clearstream that apply to such transfer or exchange. 

“Asset Sale” means: 
 (1) the sale, lease, conveyance or other disposition of any assets or rights; provided that the sale, lease, conveyance or 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 Subsidiaries. 
 Notwithstanding the preceding, none of the following items will be deemed to be an
Asset Sale: 
 (1) any sale, assignment, lease, license, transfer, abandonment or other disposition of
(A) damaged, worn-out, unserviceable or other obsolete or excess equipment or other property or (B) other property no longer necessary for the proper conduct of the business of Holly Energy Partners or any of its Restricted Subsidiaries;

 (2) any single transaction or series of related transactions that: (a) involves assets having a Fair
Market Value of less than $30.0 million or (b) results in net proceeds to Holly Energy Partners and its Restricted Subsidiaries of less than $30.0 million; 
 (3) a transfer of assets between or among Holly Energy Partners and its Restricted Subsidiaries; 
 (4) an issuance of Equity Interests by a Restricted Subsidiary of Holly Energy Partners to Holly Energy Partners or to a Restricted Subsidiary of Holly Energy Partners; 

(5) the sale or lease of products, services or accounts receivable in the ordinary course of business; 

(6) the sale or other disposition of cash or Cash Equivalents, Hedging Obligations or other financial instruments in the
ordinary course of business; 
 (7) a Restricted Payment that does not violate Section 4.07 hereof or a
Permitted Investment; 
 (8) any trade or exchange by Holly Energy Partners or any Restricted Subsidiary of
properties or assets of any type for properties or assets of any type owned or held by another Person, including any disposition of some but not all of the Equity Interests of a Restricted Subsidiary in exchange for assets or properties and after
which the Person whose Equity Interests 

  
 2 

 
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; 

(9) the creation or perfection of a Lien that is not prohibited by Section 4.12 hereof; 

(10) surrender or waiver of contract rights or the settlement, release or surrender of contract, tort or other claims of
any kind;

 (12) any disposition of
defaulted receivables that arose in the ordinary course of business for collection. 
 “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 for which such lease has been extended or may, at the option of the lessor, be extended. As used in the preceding sentence, “net rental payments” under any lease for any such period shall mean the sum of rental and
other payments required 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.”

 “Available Cash” has the meaning assigned to such term in the Partnership Agreement, as in effect on the
Issue Date. 
 “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, except that in calculating the beneficial ownership of any particular “person” (as that term is used in Section 13(d)(3) of the Exchange Act), such “person” will be deemed to have beneficial ownership of all
securities that 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; 

  
 3 

 (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) 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. 
 “Broker-Dealer” has the meaning set forth in the Registration Rights Agreement.

 “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; 
 (3) in the case of a partnership or limited liability
company, 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; 
 (3) time
deposits with, certificates of deposit, bankers’ acceptances or Eurodollar time deposits of, any commercial bank that (a) is organized under the laws of the United States of America, any state thereof or the District of Columbia or is the
principal banking subsidiary of a bank holding company organized under the laws of the United States of America, any state thereof or the District of Columbia or any United States branch of a foreign bank, and is a member of the Federal Reserve
System, (b) issues long term securities with a rating of at least A- (or then equivalent

capital and surplus of at least $500,000,000, in each case with maturities of not more than twenty-four (24) months from the date of acquisition thereof; 
 (4) commercial paper of an issuer rated at least “A-2” (or the then equivalent grade) by S&P or “P-2” (or the then equivalent grade) by Moody’s at the time of acquisition or
guaranteed by a letter of credit issued by a financial institution rated at least A- (or then equivalent grade, in each case 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 clause (3) of this definition, in each case having a tenor of not more than 270 days; 

(5) taxable and tax-exempt municipal securities rated at least A- (or then equivalent grade) by S&P and A3 (or then
equivalent grade) by Moody’s, including variable rate municipal securities, having maturities or put rights of not more than twenty-four (24) months from the date of acquisition; 

(6) corporate or bank debt of an issuer rated at least A- (or then equivalent grade, in each case with a 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 having maturities of not more than twenty-four (24) months from the date of acquisition;

 The Trustee may appoint an authenticating agent acceptable to the Issuers to authenticate Notes. An authenticating agent may
authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as an Agent to deal with Holders or an Affiliate
of the Issuers. 
 Section 2.03 Registrar and Paying Agent. 

The Issuers will maintain an office or agency where Notes may be presented for registration of transfer or for exchange
(“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Notes and of their transfer and exchange. The Issuers may appoint one or
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’ 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 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 and Special Interest, if any, 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 

  
 27 

 
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 and shall otherwise comply with TIA
§ 312(a). 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 and the Issuers shall otherwise comply with TIA § 312(a). 
 Section 2.06 Transfer and Exchange.

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 120 days after the date of such notice from the Depositary;

exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Sections 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

 (1) To permit registrations of transfers and exchanges, the Issuers will
execute and the Trustee will authenticate Global Notes and Definitive Notes upon receipt of an Authentication Order in accordance with Section 2.02 hereof or at the Registrar’s request. 

(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 9.05 hereof). 
 (3) The Registrar will not be required to register the transfer of or exchange of any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

 (4) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes
or Definitive Notes will be the valid obligations of the Issuers, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

 (5) Neither the Registrar nor the Issuers will be required: 

(A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15
days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection; 
 (B) to register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part; or

Agent or the Issuers shall be affected by notice to the contrary. 
 (7) The Trustee will authenticate Global

Section 2.07 Replacement Notes. 
 If any mutilated Note is surrendered to the Trustee or the Issuers and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Issuers will issue and the
Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are met. If required by the Trustee or the Issuers, an indemnity bond must be supplied by

  
 39 

 
the Holder that is sufficient in the judgment of the Trustee and the Issuers to protect 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 equally and proportionately with all other Notes duly issued hereunder.

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 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, on a redemption date or 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.

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

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 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

thereof; or

(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 defeasance, redemption, repurchase or other acquisition 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;

 50

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

 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. 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 case of amounts under $50.0 million, by an officer of the General Partner and, in the case of amounts over $50.0 million, by the Board of Directors of the
General Partner, whose resolution with respect thereto shall be delivered to the trustee. 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 (11), 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 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

  
 51 

 
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. 
 (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;

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; 

  
 52 

 (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; 

(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) secured Indebtedness that limits the right of the debtor to dispose of the assets securing such Indebtedness and any
related encumbrance or restriction contained in security agreements, mortgages or purchase money agreements. 
 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 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) $575.0 million and (b) the sum of $460.0 million and 20% of Consolidated Net
Tangible Assets, in each case, less the aggregate amount of all Net Proceeds of Asset Sales or casualty events applied by Holly Energy Partners or any of its Restricted Subsidiaries since the Issue Date to repay any term Indebtedness under a
Credit Facility; 

  
 53 

 (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 and the Exchange Notes and the related Note Guarantees to be issued pursuant to the Registration Rights Agreement; 

(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) $50.0 million and (b) 5.0% of Consolidated Net Tangible Assets; 
 (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) or (4) 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 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; provided that if the Indebtedness being guaranteed
is subordinated to or pari passu with the Notes, then the Guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness guaranteed; 

  
 54 

 (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 Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument inadvertently drawn against insufficient funds, so
long as such Indebtedness is covered within five business days; 
 (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; 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 Equity 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; 
 (13) the incurrence of Indebtedness arising from agreements with Holly Energy
Partners or any of its Restricted Subsidiaries providing for indemnification, adjustment of purchase price, earn-outs, or similar obligations, in each case, incurred or assumed in connection with the disposition or acquisition of any business,
assets or a Subsidiary in accordance with the terms of the indenture, other than guarantees of Indebtedness incurred or assumed by any Person acquiring all or any portion of such business, assets or Subsidiary for the purpose of financing such
acquisition; and 
 (14) 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) $50.0 million and (b) 5.0 % of Consolidated Net Tangible Assets. 

Holly Energy Partners will not incur, and will not permit any Guarantor to incur, any Indebtedness (including Permitted Debt) that is
contractually subordinated in right of payment to any other Indebtedness of Holly Energy Partners 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 solely by virtue of being unsecured or by virtue of
being secured on a first or junior Lien basis. 

  
 55 

 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 (14) 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 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. 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. 
 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; 

(2) such Fair Market Value is determined by (a) an executive Officer of the General Partner if the value is less than
$50.0 million, as evidenced by an Officers’ Certificate delivered to the Trustee, or (b) the Board of Directors of the General Partner if the value is $50.0 million or more, as evidenced by a resolution of such Board of Directors of the
General Partners; and 

  
 56 

 (3) at least 75% of the consideration received in the Asset Sale by Holly
Energy Partners or such Restricted Subsidiary is in the form of cash or Cash Equivalents. For purposes of this provision, each of the following shall be deemed to be cash: 

(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 Guarantee) that are assumed by the transferee of any such assets pursuant to a customary 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; and 
 (C) any
stock or assets of the kind referred to in clauses (2) or (4) of the next succeeding paragraph. 
 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 the applicable Restricted Subsidiary may temporarily reduce
revolving credit borrowings or otherwise invest the Net Proceeds in any manner that is not prohibited by this Indenture. 

  
 57 

 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
and Special 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 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”), 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 would have been obtained in a comparable transaction by Holly Energy Partners or such Restricted Subsidiary with an unrelated Person; 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 $25.0 million, a resolution of the Board of Directors of the General Partner 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 a majority of the disinterested members of the Board of Directors of Holly Energy Partners 

(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, 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; 

  
 58 

 (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

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

Holly Energy Partners or any Restricted Subsidiary of its obligations under, any future amendment to such agreements or under any such similar agreements shall only be permitted by this clause (9) to the extent that the terms of any such

 Holly Energy Partners will not and will not permit any of its Restricted Subsidiaries to, create, incur, assume or otherwise cause or suffer to exist or become effective any Lien of any kind (other than
Permitted Liens) securing Indebtedness, Attributable Debt or trade payables upon any of their property or assets, now owned or hereafter acquired, unless all payments due under this Indenture and the Notes are secured on an equal and ratable basis
with the obligations so secured until such time as such obligations are no longer secured by a Lien. 
 Section 4.13 Business
Activities. 
 Holly Energy Partners will not, and will not permit any of its Restricted Subsidiaries to, engage in any
business other than Permitted Businesses, except to such extent as would not be material to Holly Energy Partners and its Restricted Subsidiaries taken as a whole. 
 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: 

(1) its limited partnership existence, and the corporate, partnership or other existence of each of its 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 Board of Directors 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 and Special Interest, if any, on the Notes repurchased to, but excluding, the date of purchase,
subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant interest payment date (the “Change of Control Payment”). Within 30 days following any Change of Control, the Issuers will
mail 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; 

  
 60 

 (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 mailed (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; 
 (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 

  
 61 

 
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. 
 Section 4.16 Limitation on Sale and Leaseback Transactions.

 Holly Energy Partners will not, and will not permit any of its Restricted Subsidiaries to, enter into any sale and leaseback
transaction; provided that Holly Energy Partners or any Guarantor may enter into a sale and leaseback transaction if: 
 (1) Holly Energy Partners or that Guarantor, as applicable, could have (a) incurred Indebtedness in an amount equal to the Attributable Debt relating to such sale and leaseback transaction under the
Fixed Charge Coverage Ratio test in Section 4.09(a) hereof and (b) incurred a Lien to secure such Indebtedness pursuant to the provisions of Section 4.12 hereof; 

(2) the gross cash proceeds of that sale and leaseback transaction are at least equal to the Fair Market Value, as
determined in good faith by the Board of Directors of the General Partner and set forth in an Officers’ Certificate delivered to the Trustee, of the property that is the subject of that sale and leaseback transaction; and 

(3) the transfer of assets in that sale and leaseback transaction is permitted by, and Holly Energy Partners applies the
proceeds of such transaction in compliance with, Section 4.10 hereof. 
 Section 4.17 Payments for Consent. 

Holly Energy Partners will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, pay or cause to be paid
any consideration to or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions of this Indenture or the Notes unless such consideration is offered to be paid and is paid
to all Holders of the Notes that consent, waive or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement. 
 Section 4.18 Additional Guarantees. 
 If Holly Energy Partners or any
of its Restricted Subsidiaries acquires or creates another Domestic Subsidiary after the Issue Date that Guarantees Indebtedness of Holly Energy Partners or any of its Subsidiaries under a Credit Facility, then that newly acquired or created
Domestic Subsidiary will become a Guarantor and execute a supplemental indenture and deliver an Opinion of Counsel satisfactory to the Trustee within 30 days of the date on which it was acquired or created; provided that any Domestic
Subsidiary that constitutes an Immaterial Subsidiary need not become a Guarantor until such time as it 

  
 62 

 
ceases to be an Immaterial Subsidiary. Each Note Guarantee of a Domestic Subsidiary shall provide by its terms that it shall be automatically released if (i) that Domestic Subsidiary does
not Guarantee Indebtedness of Holly Energy Partners or any of its Subsidiaries under a Credit Facility or (ii) that Domestic Subsidiary becomes an Unrestricted Subsidiary. The form of such Note Guarantee is attached as Exhibit E hereto.

 Section 4.19 Designation of Restricted and Unrestricted Subsidiaries. 

The Board of Directors of the General Partner 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 reduce the amount available for Restricted Payments under Section 4.07 hereof or 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 the General Partner 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 Suspension of Covenants. 

(a) During any period when the Notes have an Investment Grade Rating from both Rating Agencies and no Default or Event of Default has
occurred and is continuing under this Indenture, then, beginning on that day and subject to the provisions of Section 4.20(c), Holly Energy Partners and its Restricted Subsidiaries will not be subject to the following provisions of this
Indenture: 
 (1) Section 4.10; 
 (2) Section 4.07; 
 (3) Section 4.09; 

(4) Section 4.19; 
 (5) Section 4.11; 

  
 63 

 (6) Section 4.13; 

(7) Clause 4(B) of Section 5.01; 
 (8) Section 4.08; and 
 (9) Clauses 1(A) and (3) of Section 4.16
(collectively, the “Suspended Covenants”). 
 (b) During any period that the covenants listed in
Section 4.20(a) have been suspended, the Board of Directors of the General Partner may not designate any of Holly Energy Partners’ Subsidiaries as Unrestricted Subsidiaries pursuant to Section 4.19 or clause (2) of the definition
of Unrestricted Subsidiary. 
 (c) In the event that Holly Energy Partners and its Restricted Subsidiaries are not subject to
the Suspended Covenants for any period of time as a result of the foregoing, and subsequently either of the Rating Agencies withdraws its ratings or downgrades the ratings assigned to the Notes below the Investment Grade Ratings so that the Notes do
not have an Investment Grade Rating from both Rating Agencies, or a Default (other than with respect to the Suspended Covenants) occurs and is continuing, Holly Energy Partners and its Restricted Subsidiaries will thereafter again be subject to the
Suspended Covenants (unless subsequently suspended pursuant to the previous paragraph), subject to the terms, conditions and obligations set forth in this Indenture (each such date of reinstatement being the “Reinstatement Date”).
Compliance with the Suspended Covenants with respect to Restricted Payments made after the Reinstatement Date will be calculated in accordance with Section 4.07 hereof as though such section had been in effect during the entire period of time
from which the Notes are issued. Notwithstanding that the Suspended Covenants shall have been reinstated, no default will be deemed to have occurred as a result of failure to comply with the Suspended Covenants during any period in which Holly
Energy Partners and its Restricted Subsidiaries are not subject to the Suspended Covenants.

 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, and Special Interest, if any, or premium, if any, on, or the principal of, the Notes. 

  
 68 

 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 and Special Interest, if any, on the Notes or to enforce the performance of any provision of the Notes or this Indenture. 
 The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder 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 not less than 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 and Special Interest, if any, 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. 

  
 69 

 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 Special Interest, if any, 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. 
 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

counsel. 
 Section 6.09 Trustee May File Proofs of Claim.

regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more

 ARTICLE 7 

TRUSTEE 
 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; 

  
 71 

 (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.

paragraphs (a), (b), and (c) of this Section 7.01. 
 (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 offered to the Trustee security and
indemnity satisfactory to it against any loss, liability or expense. 
 (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.

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.

 (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 offered 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 it must 

  
 72 

 
eliminate such conflict within 90 days, apply to the SEC for permission to continue as trustee (if this Indenture has been qualified under the TIA) 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 mail 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 and Special Interest, if any, 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 mail 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 by mail all reports as required by TIA § 313(c). 
 (b) A copy
of each report at the time of its mailing to the Holders of Notes will be mailed 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.

itself against any claim (whether asserted by the Issuers, the Guarantors, any Holder or any other Person) or 

  
 73 

 
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. 
 (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.

TIA § 313(b)(2) to the extent applicable.

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.

 (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

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. 

  
 74 

 (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 mail 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. 

Section 7.09 Successor Trustee by Merger, etc.

 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. 

  
 75 

 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: 
 (1)
the rights of Holders of outstanding Notes to receive payments in respect of the principal of, or interest and Special Interest, if any, 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 its 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, 4.16, 4.17, 4.18, 4.19 and 4.20 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). 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. 

  
 76

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 Special Interest, if any, 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; 
 (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 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 the Issuers or any Guarantor is a
party or by which the Issuers or any Guarantor is bound;

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

  
 77 

 (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 and Special Interest, if any, 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 and Special Interest, if any, on, any Note
and remaining unclaimed for two years after such principal, premium, if any, or interest and Special Interest, if any, 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 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 

  
 78 

 
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 and Special Interest, if any, 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 held by the Trustee or Paying Agent.

 Upon the request of the Issuers accompanied by a resolution of their Boards of Directors authorizing the
execution of any such amended or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the Trustee of the documents described in
Section 7.02 hereof, the Trustee 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 mail to the Holders of Notes affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Issuers to mail such notice, or any defect therein, will not, however, in any way impair or
affect the validity of any such amended or supplemental indenture or waiver. Subject to Sections 6.04 and 6.07 hereof, the Holders of a majority in aggregate principal amount of the Notes then outstanding voting as a single class may waive
compliance in a particular instance by the Issuers with any provision of this Indenture or the Notes or the Note Guarantees. However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.02 may
not (with respect to any Notes held by a non-consenting Holder): 
 (1) reduce the principal amount of Notes
whose Holders must consent to an amendment, supplement or waiver; 
 (2) reduce the principal of or change the
fixed maturity of any Note or alter the provisions with respect to the redemption of the Notes; provided, however, that any purchase or repurchase of Notes, including pursuant to Sections 4.10 or 4.15 hereof, shall not be deemed a redemption
of the Notes; 

  
 80 

 (3) reduce the rate of or change the time for payment of interest, including
default interest or Special Interest, if any, on any Note; 
 (4) waive a Default or Event of Default in the
payment of principal of, or interest, and Special Interest, if any, or premium on the Notes (except a rescission of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the then outstanding Notes and a
waiver of the payment default that resulted from such acceleration); 
 (5) make any Note payable in money other
than that stated in the Notes; 
 (6) make any change in the provisions of this Indenture relating to waivers of
past Defaults or the rights of Holders of Notes to receive payments of, principal of, or interest and Special Interest, if any, 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 4.10 or 4.15 hereof);

 (8) release any Guarantor from any of its obligations under its Note Guarantee or this Indenture, except in
accordance with the terms of this Indenture; or 
 (9) make any change in the preceding amendment and waiver
provisions. 
 Section 9.03 Compliance with Trust Indenture Act. 

Every amendment or supplement to this Indenture or the Notes will be set forth in a amended or supplemental indenture that complies with
the TIA as then in effect. 
 Section 9.04 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. 

  
 81 

 Section 9.05 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. 
 Section 9.06 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. The Issuers may not sign an amended or supplemental
indenture until the Boards of Directors of each of the Issuers approves it. 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 and Special Interest, if any, on, the Notes will be promptly paid in
full when due, whether at 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 

  
 82 

 
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 covenant that this 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, this 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 Note Guarantee, 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 purpose of this Note Guarantee. 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 confirms 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 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 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. 

  
 83 

 If an Officer whose signature is on this Indenture or on the Note Guarantee no longer holds
that office at the time the Trustee authenticates the Note on which a 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 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: 

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

(2) either: 
 (a) subject to Section 10.05 hereof, the Person acquiring the property 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, its Note Guarantee and the Registration Rights Agreement 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 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. 
 Except as set forth in Articles 4 and
5 hereof, and notwithstanding clauses 2(a) and (b) above, nothing contained in this Indenture or in any of the Notes will prevent any consolidation or merger of a Guarantor with or into the Issuers or another Guarantor, or will prevent any sale
or conveyance of the property of a Guarantor as an entirety or substantially as an entirety to the Issuers or another Guarantor. 

  
 84 

 Section 10.05 Releases. 
 (a) In the event of any sale or other disposition of all or substantially all of the assets of any Guarantor, by way of merger, consolidation or otherwise, or a sale or other disposition of all of the
Capital Stock of any Guarantor, in each case 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, then such Guarantor (in the event of a sale
or other disposition, by way of merger, consolidation or otherwise, of all of the Capital Stock of such Guarantor) or the corporation acquiring the property (in the event of a sale or other disposition of all or substantially all of the assets of
such Guarantor) will be released and relieved of any obligations under its Note Guarantee; provided that 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. 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.

 (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. 
 (c) Upon release of any Guarantor from
its Guarantee for Indebtedness under a Credit Facility, such Guarantor will be released and relieved of any obligations under its Note Guarantee; provided, however, that if, at any time following such release, that Guarantor incurs a
Guarantee under a Credit Facility, then such Guarantor shall be required to provide a Note Guarantee at such time. 
 (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.

 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 Special Interest, if any, 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
mailing of a notice of redemption or otherwise or will 

  
 85 

 
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 and Special Interest, if any, to the date of maturity or redemption; 

(2) no Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or
Event of Default resulting from the borrowing of funds to be applied to such deposit) and the 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; 
 (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 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 and Special Interest, 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; provided that if the Issuers have made any payment of principal of, premium, if any, or
interest and Special Interest, if any, on, any Notes because of the reinstatement of its 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.

 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 6.50% per annum from March 12, 2012 until maturity and shall pay the Special Interest, if any, payable pursuant to Section 4 of the Registration Rights Agreement referred to below. The
Issuers will pay interest and Special Interest, if any, semi-annually in arrears on March 1 and September 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 September 1, 2012. The Issuers will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time on demand at the
rate then in effect to the extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at a rate that is 1.00% higher than the applicable interest rate on the Notes to the
extent lawful; it will pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest and Special Interest (without regard to any applicable grace period) at the same rate to the extent
lawful. 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) and Special Interest, if any, to the Persons who are registered Holders of Notes at the close of business on the
February 15 or August 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 Special Interest, if any, 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 and Special Interest, if any, 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, premium and Special Interest, if any, on, all 

  
 4 

 
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 March 12, 2012 (the
“Indenture”) among the Issuers, the Guarantors and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the TIA. 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) OPTIONAL REDEMPTION. 
 (a)
Except pursuant to paragraphs (b) and (c) of this Section 5, the Notes will not be redeemable at the Issuers’ option prior to March 1, 2016. On or after March 1, 2016, the Issuers may redeem all or a part of the Notes
upon not less than 30 nor more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest and Special Interest, if any, on the Notes redeemed to the applicable
Redemption Date, if redeemed during the twelve-month period beginning on March 1 of each year indicated below, subject to the rights of Holders of Notes on the relevant record date to receive interest on the relevant interest payment date:

  

					
	 Year
	  	Percentage	 
	 2016
	  	 	103.250%	  
	 2017
	  	 	101.625%	  
	 2018 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 March 1, 2015, 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
at a redemption price of 106.500% of the principal amount thereof, plus accrued and unpaid interest and Special Interest, if any, to the redemption date (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), with 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 90 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 March 1, 2016, the Issuers may also redeem all or a part of the Notes, upon not less than 30 nor more 

  
 5 

 
than 60 days’ prior notice mailed by first-class mail to each Holder’s registered address, 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 and Special Interest, if any, to the Redemption Date, subject to the rights of Holders on the relevant record date to receive interest due on the relevant interest payment date. 

For purposes of this Paragraph 5, “Applicable Premium” means, with respect to any Note on any redemption date, the
greater of: (1) 1.00% of the principal amount of the Note; or (2) the excess of: (a) the present value at such redemption date of (i) the redemption price of the Note at March 1, 2016 (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 March 1, 2016 (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 any redemption date, the yield to maturity as of such redemption
date 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 March 1, 2016; provided, however, that if the
period from the redemption date to March 1, 2016, 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. 
 (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 and Special Interest, if any, 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 (the “Change of Control Payment”). Within 30
days following any Change of Control, the Issuers will mail 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 the Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets (an “Asset Sale Offer”) pursuant to Section 3.09 of the Indenture 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 and Special Interest, if any, to the date of
purchase, in accordance with the procedures set forth in the Indenture. To the extent that the aggregate amount of Notes and other pari passu Indebtedness tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Holly
Energy Partners (or such Restricted Subsidiary) may use such deficiency 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 such other pari passu Indebtedness to 

  
 6 

 
be purchased on a pro rata basis. Holders of Notes that are the subject of an offer to purchase will receive an Asset Sale Offer 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 at least 30 days but not more than 60 days before the redemption date to
each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be mailed more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction or
discharge of the 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. 

(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 taxes and fees 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. 
 (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 at least a majority in aggregate principal amount of the then outstanding Notes including Additional Notes, if any, voting as a single class, 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,
voting as a single class. 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 provide any additional rights or benefits to the Holders of Notes or that does not adversely affect the legal rights under the Indenture of any such
Holder, to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA, to conform the text of the Indenture 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 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 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 as any other
form of entity, in accordance with Section 5.01 of the Indenture. 
 (12) DEFAULTS AND
REMEDIES. Events of Default include: (i) default for 30 days in the payment when due of interest on, and Special Interest, if any, with respect to the Notes; (ii) default in the payment when due (at
maturity, upon redemption or otherwise) of the principal of, or premium, if any, on 

  
 7 

 
the Notes; (iii) failure by Holly Energy Partners or any of its Restricted Subsidiaries to timely consummate repurchase offers under Section 4.10 or 4.15 of the Indenture or to comply
with Section 5.01 of the Indenture; (iv) failure by Holly Energy Partners for 90 days after written notice to Holly Energy Partners by the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes then outstanding
voting as a single class to comply with Section 4.03 of the Indenture, (v) failure by Holly Energy Partners or any of its Restricted Subsidiaries for 60 days after written notice to Holly Energy Partners by the Trustee or the Holders of at
least 25% in aggregate principal amount of the Notes then outstanding voting as a single class to comply with any of the other agreements in the Indenture; (vi) default under certain other agreements relating to Indebtedness of the Issuers
which default (A) is caused by a failure to pay principal of, or interest or premium, 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 action or notice. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. Subject to certain limitations, Holders
of a majority in aggregate principal amount of the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the Notes notice of any continuing Default or Event of Default if it
determines that withholding notice is in their interest, except a Default or Event of Default relating to the payment of principal, interest and Special Interest, if any, 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 and Special Interest, if any, 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. The waiver may not be effective to waive liabilities under the federal securities laws.

 EXHIBIT F 
 FORM OF SUPPLEMENTAL INDENTURE 
 TO BE DELIVERED BY SUBSEQUENT GUARANTORS

 SUPPLEMENTAL INDENTURE (this “Supplemental Indenture”), dated as of
            , 200    , among
                     (the “Guaranteeing Subsidiary”), Holly Energy Partners, L.P., a Delaware limited partnership
(“Holly Energy Partners”), and Holly Energy Finance Corp. (“Finance Corp.” and, together with Holly Energy Partners, the “Issuers”), the other Guarantors (as defined in the Indenture referred to
herein) and U.S. Bank National Association, as trustee under the Indenture referred to below (the “Trustee”). 

W I T N E S S E T H 
 WHEREAS, the Issuers have heretofore executed and delivered to the Trustee an indenture (the “Indenture”), dated as of March 12, 2012 providing for the issuance of 6.50% Senior Notes
due 2020 (the “Notes”); 
 WHEREAS, the Indenture provides that under certain circumstances the Guaranteeing
Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing Subsidiary shall unconditionally guarantee all of the Issuers’ Obligations under the Notes and the Indenture on the terms and
conditions set forth herein (the “Note Guarantee”); and 
 WHEREAS, pursuant to Section 9.01 of the
Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture. 
 NOW, THEREFORE, in consideration of
the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as
follows: 
 1. CAPITALIZED TERMS. Capitalized terms used herein without definition shall have the
meanings assigned to them in the Indenture. 
 2. AGREEMENT TO GUARANTEE. The
Guaranteeing Subsidiary hereby agrees to provide an unconditional Guarantee on the terms and subject to the conditions set forth in the Note Guarantee and in the Indenture including but not limited to Article 10 thereof. 

4. NO RECOURSE AGAINST OTHERS. No past, present or future director, officer,
employee, incorporator, stockholder or agent of the Guaranteeing Subsidiary, as such, shall have any liability for any obligations of the Issuers or any Guaranteeing Subsidiary under the Notes, any Note Guarantees, the Indenture or this Supplemental
Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of the Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for
issuance of the Notes. Such waiver may not be effective to waive liabilities under the federal securities laws and it is the view of the SEC that such a waiver is against public policy. 

5. NEW YORK LAW TO GOVERN. THE LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS SUPPLEMENTAL INDENTURE. 

6. COUNTERPARTS. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an
original, but all of them together represent the same agreement.

 7. EFFECT OF HEADINGS. The Section headings

The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the
Guaranteeing Subsidiary and the Issuers.

 IN WITNESS WHEREOF, the parties hereto have caused this Supplemental Indenture to be duly
executed and attested, all as of the date first above written.
