                                  Scott Kriens
                  (as amended and restated February 28, 2005)

WHEREAS, Juniper Networks, Inc. ("Juniper") acknowledges that Scott Kriens has

behalf of Juniper in the performance of his duties as Chairman, Chief Executive
Officer and President of Juniper;

WHEREAS, such travel expenses include use of private aircraft for purposes of

WHEREAS, Juniper has determined that the use of private aircraft by Scott Kriens
is reasonable and necessary to properly and efficiently fulfill the critical,
frequent, and often changing demands placed on Scott Kriens in his capacity as
the Chairman, Chief Executive Officer and President of Juniper;

WHEREAS, notwithstanding the benefits derived from and need for use of private
aircraft in the conduct of Juniper business, Juniper has not committed, and does
not currently plan to commit, funds toward the purchase, in whole or in part, or
the lease of corporate aircraft;

WHEREAS, Juniper has partially reimbursed Scott Kriens for substantiated
expenses attributable to such use of private aircraft for Juniper business under
its general expense reimbursement policy;

WHEREAS, Juniper has decided to formalize its reimbursement policy for Scott
Kriens and establish a fixed rate for such reimbursement;

IT IS RESOLVED, Juniper will reimburse Scott Kriens for substantiated expenses
attributable to the use of private aircraft in connection with the performance
of services for Juniper as its Chairman, Chief Executive Officer and President,
equal to a fixed rate per flying hour in connection with any such flight (such
amount shall initially be established as $2,000 per hour and shall be subject to
periodic review based on actual ordinary operating costs); provided, however,
that the total reimbursement amount paid to Scott Kriens in connection with any
flight shall not exceed the amount permitted to be charged by the FAA under
timeshare agreements pursuant to FAR Part 91.501(d); and provided further,
however, that the total reimbursement amount with respect to flights taken in
any calendar year shall not exceed either of $650,000 or the actual total

     “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.

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.

through March 1, 2010 (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.

that the sale, lease, conveyance or other disposition of all or substantially all of the

Equity Interests have been so disposed of continues to be a Restricted Subsidiary, provided
that the fair market value of the properties or assets traded or exchanged by Holly Energy
Partners or such Restricted Subsidiary (together with any cash or Cash Equivalent together
with the liabilities assumed) is reasonably equivalent to the fair market value of the
properties or assets (together with any cash or Cash Equivalent together with liabilities
assumed) to be received by Holly Energy Partners or such Restricted Subsidiary; and provided

(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;

     (2) with respect to a partnership, the Board of Directors or Board of Managers of the

(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,

THE NOTES

Section 2.01 Form and Dating.

       (a) General. The Notes and the Trustee’s certificate of authentication will be
substantially in the form of Exhibit A hereto. The Notes may have notations, legends or
endorsements required by law, stock exchange rule or usage. Each Note will be dated the date of
its authentication. The Notes shall be in denominations of $1,000 and integral multiples
thereof.

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

       (b) Global Notes. Notes issued in global form will be substantially in the form
of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of
Interests in the Global Note” attached thereto). Notes issued in definitive form will be
substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and
without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each
Global Note will represent such of the outstanding Notes as will be specified therein and each
shall provide that it represents the aggregate principal amount of outstanding Notes from time to
time endorsed thereon and that the aggregate principal amount of outstanding Notes represented
thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and
redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease
in the aggregate principal amount of outstanding Notes represented thereby will be made by the
Trustee or the Custodian, at the direction of the Trustee, in accordance with instructions given
by the Holder thereof as required by Section 2.06 hereof.

       (c) Euroclear and Clearstream Procedures Applicable. The provisions of the
“Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of
Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook”
of Clearstream will be applicable to transfers of beneficial interests in the Regulation S Global
Notes that are held by Participants through Euroclear or Clearstream.

Section 2.02 Execution and Authentication.

     At least one Officer must sign the Notes for each of the Issuers by manual or facsimile
signature.

     If an Officer whose signature is on a Note no longer holds that office at the time a Note is
authenticated, the Note will nevertheless be valid.

     A Note will not be valid until authenticated by the manual signature of the Trustee. The
signature will be conclusive evidence that the Note has been authenticated under this Indenture.

     The Trustee will, upon receipt of a written order of the Issuers signed by two Officers of
each Issuer (an “Authentication Order”), authenticate Notes for original issue that may be validly
issued under

25

 

this Indenture, including any Additional Notes and Exchange Notes. The aggregate principal
amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes
authorized for issuance by the Issuers pursuant to one or more Authentication Orders, except as
provided in Section 2.07 hereof.

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

Section 2.05 Holder Lists.

     The Trustee will preserve in as current a form as is reasonably practicable the most
recent list available to it of the names and addresses of all Holders 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).

               (B) if the transfer will be made pursuant to Rule 903 or Rule 904, then the

          (2) Restricted Definitive Notes to Unrestricted Definitive Notes. Any Restricted
Definitive Note may be exchanged by the Holder thereof for an Unrestricted Definitive Note
or transferred to a Person or Persons who take delivery thereof in the form of an
Unrestricted Definitive Note if:

               (A) such exchange or transfer is effected pursuant to the Exchange Offer in
accordance with the Registration Rights Agreement and the Holder, in the case of an
exchange, or the transferee, in the case of a transfer, certifies in the applicable
Letter of Transmittal that it is not (i) a Broker-Dealer, (ii) a Person
participating in the distribution of the Exchange Notes or (iii) a Person who is an

and, in each such case set forth in this subparagraph (D), if the Registrar so

and that the restrictions on transfer contained herein and in the Private Placement
Legend are no longer required in order to maintain compliance with the Securities
Act.

          (3) Unrestricted Definitive Notes to Unrestricted Definitive Notes. A Holder of
Unrestricted Definitive Notes may transfer such Notes to a Person who takes delivery thereof
in the form of an Unrestricted Definitive Note. Upon receipt of a request to register such
a transfer, the Registrar shall register the Unrestricted Definitive Notes pursuant to the
instructions from the Holder thereof.

       (f) Exchange Offer. Upon the occurrence of the Exchange Offer in accordance with
the Registration Rights Agreement, the Issuers will issue and, upon receipt of an Authentication
Order in accordance with Section 2.02 hereof, the Trustee will authenticate:

          (1) one or more Unrestricted Global Notes in an aggregate principal amount equal to the
principal amount of the beneficial interests in the Restricted Global Notes accepted for
exchange in the Exchange Offer by Persons that certify in the applicable Letters of
Transmittal that (A) they are not Broker-Dealers, (B) they are not participating in a
distribution of the Exchange Notes and (C) they are not affiliates (as defined in Rule 144)
of the Issuers; and

          (2) Unrestricted Definitive Notes in an aggregate principal amount equal to the

Broker-Dealers, (B) they are not participating in a distribution of the Exchange Notes and
(C) they are not affiliates (as defined in Rule 144) of the Issuers.

     Concurrently with the issuance of such Notes, the Trustee will cause the aggregate principal
amount of the applicable Restricted Global Notes to be reduced accordingly, and the Issuers will
execute and the Trustee will authenticate and deliver to the Persons designated by the Holders of
Definitive Notes so accepted Unrestricted Definitive Notes in the appropriate principal amount.

       (g) Legends. The following legends will appear on the face of all Global Notes
and Definitive Notes issued under this Indenture unless specifically stated otherwise in the
applicable provisions of this Indenture.

          (1) Private Placement Legend.

TRANSFEROR AND AN OPINION OF COUNSEL TO THE EFFECT THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE
SECURITIES ACT, (2) TO THE ISSUERS OR THEIR RESPECTIVE SUBSIDIARIES OR (3) UNDER AN EFFECTIVE
REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND, IN EACH CASE, IN ACCORDANCE WITH ANY
APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES OR ANY OTHER APPLICABLE JURISDICTION
AND THE INDENTURE GOVERNING THE NOTES AND (B) THE HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS
REQUIRED TO, NOTIFY ANY PURCHASER FROM IT OF THE NOTE EVIDENCED HEREBY OF THE RESALE RESTRICTIONS
SET FORTH IN (A) ABOVE. IF ANY RESALE OR OTHER TRANSFER OF ANY NOTE IS PROPOSED TO BE MADE UNDER
CLAUSE (A)(1)(D) ABOVE WHILE THESE TRANSFER RESTRICTIONS ARE IN FORCE THEN THE TRANSFEROR SHALL
DELIVER A LETTER FROM THE TRANSFEREE TO THE TRUSTEE WHICH SHALL PROVIDE, AMONG OTHER THINGS, THAT
THE TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR AND THAT IT IS ACQUIRING THE SECURITIES FOR
INVESTMENT PURPOSES AND NOT FOR DISTRIBUTION IN VIOLATION OF THE SECURITIES ACT.”

               (B) Notwithstanding the foregoing, any Global Note or Definitive Note issued
pursuant to subparagraphs (b)(4), (c)(2), (c)(3), (d)(2), (d)(3), (e)(2), (e)(3) or
(f) of this Section 2.06 (and all Notes issued in exchange therefor or substitution

          (2) Global Note Legend. Each Global Note will bear a legend in substantially the
following form:

“THIS GLOBAL NOTE IS HELD BY THE DEPOSITARY (AS DEFINED IN THE INDENTURE GOVERNING THIS NOTE) OR
ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO

36

 

UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR NOTES IN DEFINITIVE FORM, THIS NOTE MAY
NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A
NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE
DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY.

REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME
OF CEDE & CO. OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND
ANY PAYMENT IS MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO
ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.”

       (h) Cancellation and/or Adjustment of Global Notes. At such time as all
beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a
particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each
such Global Note will be returned to or retained and canceled by the Trustee in accordance with
Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a
Global Note is exchanged for or transferred to a Person who will take delivery thereof in the
form of a beneficial interest in another Global Note or for Definitive Notes, the principal
amount of Notes represented by such Global Note will be reduced accordingly and an endorsement
will be made on such Global Note by the Trustee or by the Depositary at the direction of the
Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or
transferred to a Person who will take delivery thereof in the form of a beneficial interest in
another Global Note, such other Global Note will be increased accordingly and an endorsement will
be made on such Global Note by the Trustee or by the Depositary at the direction of the Trustee
to reflect such increase.

       (i) General Provisions Relating to Transfers and Exchanges.

          (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 tax or similar
governmental charge payable in connection therewith (other than any such transfer 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.

37

 

          (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

               (C) to register the transfer of or to exchange a Note between a record date and
the next succeeding interest payment date.

          (6) Prior to due presentment for the registration of a transfer of any Note, the
Trustee, any Agent and the Issuers may deem and treat the Person in whose name any Note is
registered as the absolute owner of such Note for the purpose of receiving payment of
principal of and interest on such Notes and for all other purposes, and none of the Trustee,
any Agent or the Issuers shall be affected by notice to the contrary.

          (7) The Trustee will authenticate Global Notes and Definitive Notes in accordance with
the provisions of Section 2.02 hereof.

          (8) All certifications, certificates and Opinions of Counsel required to be submitted
to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or
exchange may be submitted by facsimile.

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 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.

Section 2.08 Outstanding Notes.

     The Notes outstanding at any time are all the Notes authenticated by the Trustee except
for those canceled by it, those delivered to it for cancellation, those reductions in the interest
in a Global Note effected by the Trustee in accordance with the provisions hereof, and those
described in this Section 2.08 as not outstanding. Except as set forth in Section 2.09 hereof, a
Note does not cease to be outstanding because the Issuers or an Affiliate of the Issuers holds the
Note; however, Notes held by Holly Energy Partners or a Subsidiary of Holly Energy Partners shall
not be deemed to be outstanding for purposes of Section 3.07(a) hereof.

     If a Note is replaced pursuant to Section 2.07 hereof, it ceases to be outstanding unless the
Trustee receives proof satisfactory to it that the replaced Note is held by a protected purchaser.

38

 

     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.

Section 2.11 Cancellation.

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

Section 2.12 Defaulted Interest.

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

REDEMPTION AND PREPAYMENT

Section 3.01 Notices to Trustee.

     If the Issuers elect to redeem Notes pursuant to the optional redemption provisions of
Section 3.07 hereof, it must furnish to the Trustee, at least 30 days but not more than 60 days
before a redemption date, an Officers’ Certificate setting forth:

          (1) the clause of this Indenture pursuant to which the redemption shall occur;

          (2) the redemption date;

          (3) the principal amount of Notes to be redeemed; and

          (4) the redemption price.

Section 3.02 Selection of Notes to Be Redeemed or Purchased.

     If less than all of the Notes are to be redeemed or purchased in an offer to purchase at
any time, the Trustee will select Notes for redemption or purchase on a pro rata basis except if
the Notes are listed on any national securities exchange, in compliance with the requirements of
the principal national securities exchange on which the Notes are listed.

     No Notes of $1,000 or less can be redeemed in part. In the event of partial redemption or
purchase by lot, the particular Notes to be redeemed or purchased will be selected, unless
otherwise provided herein, not less than 30 nor more than 60 days prior to the redemption or
purchase date by the Trustee from the outstanding Notes not previously called for redemption or
purchase.

     The Trustee will promptly notify the Issuers in writing of the Notes selected for redemption
or purchase and, in the case of any Note selected for partial redemption or purchase, the principal
amount thereof to be redeemed or purchased. Notes and portions of Notes selected will be in
amounts of $1,000 or whole multiples of $1,000; except that if all of the Notes of a Holder are to
be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a
multiple of $1,000, shall be redeemed or purchased. Except as provided in the preceding sentence,
provisions of this Indenture that apply to Notes called for redemption or purchase also apply to
portions of Notes called for redemption or purchase.

Section 3.03 Notice of Redemption.

     Subject to the provisions of Section 3.09 hereof, at least 30 days but not more than 60
days before a redemption date, the Issuers will mail or cause to be mailed, by first class mail, a
notice of redemption 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 and discharge of
this Indenture pursuant to Articles 8 or 11 hereof.

     The notice will identify the Notes to be redeemed and will state:

          (1) the redemption date;

40

 

          (2) the redemption price;

          (3) if any Note is being redeemed in part, the portion of the principal amount of such
Note to be redeemed and that, after the redemption date upon surrender of such Note, a new
Note or Notes in principal amount equal to the unredeemed portion will be issued upon
cancellation of the original Note;

          (4) the name and address of the Paying Agent;

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

          (6) that, unless the Issuers default in making such redemption payment, interest on
Notes called for redemption ceases to accrue on and after the redemption date;

          (7) the paragraph of the Notes and/or Section of this Indenture pursuant to which the
Notes called for redemption are being redeemed; and

          (8) that no representation is made as to the correctness or accuracy of the CUSIP
number, if any, listed in such notice or printed on the Notes.

     At the Issuers’ request, the Trustee will give the notice of redemption in the Issuers’ names
and at their expense; provided, however, that the Issuers have delivered to the Trustee, at least
45 days prior to the redemption date, an Officers’ Certificate requesting that the Trustee give
such notice and setting forth the information to be stated in such notice as provided in the
preceding paragraph.

Section 3.04 Effect of Notice of Redemption.

     Once notice of redemption is mailed in accordance with Section 3.03 hereof, Notes called
for redemption become irrevocably due and payable on the redemption date at the redemption price.
A notice of redemption may not be conditional.

Section 3.05 Deposit of Redemption or Purchase Price.

     On or prior to the redemption or purchase date, the Issuers will deposit with the Trustee
or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued
interest and Liquidated Damages, if any, on all Notes to be redeemed or purchased on that date.
The Trustee or the Paying Agent will promptly return to the Issuers any money deposited with the
Trustee or the Paying Agent by the Issuers in excess of the amounts necessary to pay the redemption
or purchase price of, and accrued interest and Liquidated Damages, if any, on, all Notes to be
redeemed or purchased.

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

41

 

Section 3.06 Notes Redeemed or Purchased in Part.

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

       (d) At any time prior to March 1, 2010, the Issuers may also redeem all or a part
of the Notes, upon not less than 30 nor more 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

Liquidated Damages, if any, to the date of redemption (the “Redemption Date”), subject to the
rights of Holders on the relevant record date to receive interest due on the relevant interest

provisions of Sections 3.01 through 3.06 hereof.

Section 3.08 Mandatory Redemption.

Offer will remain open for a period of at least 20 Business Days following its commencement and not

if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in
response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same
manner as interest payments are made.

     If the Purchase Date is on or after an interest record date and on or before the related
interest payment date, any accrued and unpaid interest and Liquidated Damages, if any, will be paid
to the Person in whose name a Note is registered at the close of business on such record date, and
no additional interest will be payable to Holders who tender Notes pursuant to the Asset Sale
Offer.

     Upon the commencement of an Asset Sale Offer, the Issuers will send, by first class mail, a
notice to the Trustee and each of the Holders, with a copy to the Trustee. The notice will contain
all instructions and materials necessary to enable such Holders to tender Notes pursuant to the
Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

          (1) that the Asset Sale Offer is being made pursuant to this Section 3.09 and Section
4.10 hereof and the length of time the Asset Sale Offer will remain open;

43

 

          (2) the Offer Amount, the purchase price and the Purchase Date;

          (3) that any Note not tendered or accepted for payment will continue to accrue
interest;

          (4) that, unless the Issuers default in making such payment, any Note accepted for
payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase
Date;

          (5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer may
elect to have Notes purchased in integral multiples of $1,000 only;

          (6) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will
be required to surrender the Note, with the form entitled “Option of Holder to Elect
Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the
Issuers, a Depositary, if appointed by the Issuers, or a Paying Agent at the address
specified in the notice at least three days before the Purchase Date;

          (7) that Holders will be entitled to withdraw their election if the Issuers, the
Depositary or the Paying Agent, as the case may be, receives, not later than the expiration
of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the
name of the Holder, the principal amount of the Note the Holder delivered for purchase and a
statement that such Holder is withdrawing his election to have such Note purchased;

          (8) that, if the aggregate principal amount of Notes and other pari passu Indebtedness
surrendered by holders thereof exceeds the Offer Amount, the Issuers will select the Notes
and other pari passu Indebtedness to be purchased on a pro rata basis based on the principal
amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as
may be deemed appropriate by the Issuers so that only Notes in denominations of $1,000, or
integral multiples thereof, will be purchased); and

          (9) that Holders whose Notes were purchased only in part will be issued new Notes equal
in principal amount to the unpurchased portion of the Notes surrendered (or transferred by
book-entry transfer).

     On or before the Purchase Date, the Issuers will, to the extent lawful, accept for payment, on
a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered
pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes
tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted
together with an Officers’ Certificate stating that such Notes or portions thereof were accepted
for payment by the Issuers in accordance with the terms of this Section 3.09. The Issuers, the
Depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than
five days after the Purchase Date) mail or deliver to each tendering Holder an amount equal to the
purchase price of the Notes tendered by such Holder and accepted by the Issuers for purchase, and
the Issuers will promptly issue a new Note, and the Trustee, upon written request from the Issuers,
will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to
such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any
Note not so accepted shall be promptly mailed or delivered by the Issuers to the Holder thereof.
The Issuers will publicly announce the results of the Asset Sale Offer on the Purchase Date.

     Other than as specifically provided in this Section 3.09, any purchase pursuant to this
Section 3.09 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

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 $15.0 million, by an
officer of the General Partner and, in the case of amounts over $15.0 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) — (8), 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

          (1) agreements as in effect on the date of this Indenture 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
date of this Indenture;

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

          (3) applicable law, rule, regulation or order;

and Capital Lease Obligations that impose restrictions on the property purchased or leased
of the nature described in clause (3) of Section 4.08(a) hereof;

          (8) Permitted Refinancing Indebtedness; provided that the restrictions contained in the

restrictive, taken as a whole, than those contained in the agreements governing the
Indebtedness being refinanced;

          (9) 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;

to this clause (4), not to exceed $20.0 million at any time outstanding;

          (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);

52

 

          (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 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, Finance Corp. or any of the Guarantors of
Indebtedness of Holly Energy Partners, Finance Corp. 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; and

          (9) 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 $40.0 million.

     Holly Energy Partners will not incur, and will not permit Finance Corp. or any Guarantor to
incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of
payment to any other Indebtedness of Holly Energy Partners, Finance Corp. or such Guarantor unless
such Indebtedness is also contractually subordinated in right of payment to the Notes and the
applicable Note Guarantee on substantially identical terms; provided, however, that no Indebtedness
shall be deemed to be contractually subordinated in right of payment to any other Indebtedness of
Holly Energy Partners solely by virtue of being unsecured or by virtue of being secured on a first
or junior Lien basis.

     For purposes of determining compliance with this Section 4.09, in the event that an item of
proposed Indebtedness meets the criteria of more than one of the categories of Permitted Debt
described in clauses (1) through (9) 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.

53

 

     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.

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 $15.0 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 $15.0 million or more, as evidenced by a resolution of such Board of Directors of the
General Partners; and

          (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; and

               (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.

     Within 360 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 360-day period)
with a permanent reduction in availability for any revolving credit Indebtedness;

54

 

          (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.

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.

     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 $20.0 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 Liquidated Damages, 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:

55

 

               (A) 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; and

               (B) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $50.0 million, a written
opinion as to the fairness to Holly Energy Partners or such Subsidiary of such
Affiliate Transaction from a financial point of view issued by an accounting,
appraisal or investment banking firm of recognized industry standing.

       (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) any employment agreement, equity award, equity option or equity appreciation
agreement or plan, officer or director indemnification agreement or any similar arrangement
entered into by Holly Energy Partners or any of its Restricted Subsidiaries or the General
Partner in the ordinary course of business and payments pursuant thereto;

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

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

          (4) any issuance of Equity Interests (other than Disqualified Equity) of Holly Energy
Partners to Affiliates of Holly Energy Partners;

          (5) Restricted Payments or Permitted Investments that do not violate Section 4.07
hereof;

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

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

          (8) loans or advances to employees in the ordinary course of business not to exceed
$1.0 million in the aggregate at any one time outstanding; and

          (9) the existence of, or the performance by Holly Energy Partners or any Restricted
Subsidiary of its obligations under the terms of, any agreements that are described in the
Offering Memorandum under the heading “Certain relationships and related party transactions”
to which it is a party as of the closing date of the Acquisition on the terms described in
the Offering

56

 

Memorandum and any amendments thereto and any similar agreements which it may
enter into thereafter; provided, however, that the existence of, or the performance by Holly
Energy Partners or any Restricted Subsidiary of its obligations under, any future amendment
to such agreements or under any such similar agreements shall only be permitted by this
clause (9) to the extent that the terms of any such amendment or new agreement, taken as a
whole, are not less favorable to the Holders in any material respect as determined by the
Board of Directors of the General Partner in its reasonable good faith judgment upon a
recommendation of Holly Energy Partners’ Conflicts Committee.

Section 4.12 Liens.

     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) 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 (other than Permitted Liens).

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.

57

 

       (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 $1,000
or an integral multiple of $1,000) 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
Liquidated Damages, 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;

          (2) the purchase price and the purchase date, which shall be no earlier than 20
Business 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 $1,000 in principal amount or an integral multiple
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;

58

 

          (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, and the Trustee will promptly authenticate and mail (or cause to be
transferred by book entry) to each Holder a new Note equal in principal amount to any unpurchased
portion of the Notes surrendered, if any; provided, that each new Note will be in a principal
amount of $1,000 or an integral multiple of $1,000. 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

59

 

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 date of this Indenture 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 10 Business 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 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 that Domestic Subsidiary does not Guarantee Indebtedness of Holly
Energy Partners or any of its Subsidiaries under a Credit Facility. 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, Holly Energy Partners and its Restricted Subsidiaries will not be subject to the
following provisions of this Indenture:

60

 

(1) Section 4.10;

(2) Section 4.07;

(3) Section 4.09;

(4) Section 4.19;

(5) Section 4.11;

(6) Section 4.13;

(7) Section 4.18;

(8) Clause 4(B) of Section 5.01; and

(9) Clauses 1(A) and (3) of Section 4.16 (collectively, the “Suspended Covenants”).

       (b) 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.

the same had occurred at the beginning of the applicable Reference Period, not less
than the Fixed Charge Coverage Ratio of Holly Energy Partners immediately prior to
such transaction; and

          (5) such Issuer has delivered to the Trustee an Officers’ Certificate and an Opinion of
Counsel, each stating that such consolidation, merger or disposition and such supplemental
indenture (if any) comply with this Indenture and all conditions precedent therein relating
to such transaction have been satisfied;

provided that clause (4) shall not apply to any sale of assets of a Restricted Subsidiary to Holly
Energy Partners or another Restricted Subsidiary or the merger, or consolidation of a Restricted
Subsidiary into any Restricted Subsidiary or Holly Energy Partners.

       (b) Notwithstanding Section 5.01(a), Holly Energy Partners is permitted to
reorganize as any other form of entity in accordance with the procedures established in this
Indenture; provided that:

          (1) the reorganization involves the conversion (by merger, sale, contribution or
exchange of assets or otherwise) of Holly Energy Partners into a form of entity other than a
limited partnership formed under Delaware law;

          (2) the entity so formed by or resulting from such reorganization is an entity
organized or existing under the laws of the United States, any state thereof or the District
of Columbia;

          (3) the entity so formed by or resulting from such reorganization assumes all the
Obligations of Holly Energy Partners under the Notes, this Indenture and the Registration
Rights Agreement pursuant to agreements reasonably satisfactory to the Trustee;

62

 

          (4) immediately after such reorganization no Default or Event of Default exists; and

          (5) such reorganization is not adverse to the Holders of the Notes (for purposes of
this clause (5) it is stipulated that such reorganization shall not be considered adverse to
the Holders of the Notes solely because the successor or survivor of such reorganization (a)
is subject to federal or state income taxation as an entity or (b) is considered to be an
“includible corporation” of an affiliated group of corporations within the meaning of
Section 1504(b)(i) of the Code or any similar state or local law).

       (c) A Guarantor may not sell or otherwise dispose of all or substantially all of
its properties or assets to, or consolidate with or merge with or into (whether or not such
Guarantor is the surviving Person), another Person, other than Holly Energy Partners or another
Guarantor, unless:

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

          (2) either:

               (A) the Person acquiring the properties or assets in any such sale or other
disposition or the Person formed by or surviving any such consolidation or merger
(if other than Holly Energy Partners or the Guarantor) unconditionally assumes all
the obligations of that Guarantor, pursuant to a supplemental indenture
substantially in the form specified in this Indenture, under the Notes, this
Indenture and its Subsidiary Guarantee on terms set forth herein and therein; or

               (B) the Net Proceeds of such sale or other disposition are applied in
accordance with Section 4.10 hereof.

Section 5.02 Successor Corporation Substituted.

     Upon any consolidation or merger, or any sale, assignment, transfer, lease, conveyance or
other disposition of all or substantially all of the properties or assets of Holly Energy Partners
in a transaction that is subject to, and that complies with the provisions of, Section 5.01 hereof,
the successor Person formed by such consolidation or into or with which Holly Energy Partners is
merged or to which such sale, assignment, transfer, lease, conveyance or other disposition is made
shall succeed to, and be substituted for (so that from and after the date of such consolidation,
merger, sale, assignment, transfer, lease, conveyance or other disposition, the provisions of this
Indenture referring to the “Holly Energy Partners” shall refer instead to the successor Person and
not to Holly Energy Partners), and may exercise every right and power of Holly Energy Partners
under this Indenture with the same effect as if such successor Person had been named as Holly
Energy Partners herein.

or Guarantee now exists, or is created after the date of this Indenture, if that default:

               (A) is caused by a failure to pay principal of, or interest or premium, if any,

Indebtedness on the date of such default (a “Payment Default”); or

               (B) results in the acceleration of such Indebtedness prior to its express

Significant Subsidiary in an involuntary case;

               (B) appoints a custodian of an Issuer or any of Holly Energy Partners’

or any of Holly Energy Partners’ Restricted Subsidiaries that is a Significant

taken together, would constitute a Significant Subsidiary; or

               (C) orders the liquidation of an Issuer or any of Holly Energy Partners’
Restricted Subsidiaries that is a Significant Subsidiary or any group of Restricted
Subsidiaries of Holly Energy Partners that, taken together, would constitute a

and the order or decree remains unstayed and in effect for 60 consecutive days; and

          (9) except as permitted by this Indenture, any Note Guarantee is held in any judicial
proceeding to be unenforceable or invalid or ceases for any reason to be in full force and
effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or
disaffirms its obligations under its Note Guarantee.

Section 6.02 Acceleration.

     In the case of an Event of Default specified in clause (7) or (8) of Section 6.01 hereof,
with respect to Finance Corp., Holly Energy Partners or any Restricted Subsidiary of Holly Energy
Partners that is a Significant Subsidiary or any group of Restricted Subsidiaries of Holly Energy
Partners that, taken together, would constitute a Significant Subsidiary, all outstanding Notes
will become due and payable immediately without further action or notice. If any other Event of
Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal
amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.

     Upon any such declaration, the Notes shall become due and payable immediately.

     The Holders of a majority in aggregate principal amount of the then outstanding Notes by
notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an acceleration or
waive any existing Default or Event of Default and its consequences under the Indenture except a
continuing Default or Event of Default in the payment of interest or premium or Liquidated Damages,
if any, on, or the principal of, the Notes.

Section 6.03 Other Remedies.

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

65

 

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

Section 6.05 Control by Majority.

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

Section 6.06 Limitation on Suits.

     A Holder may pursue a remedy with respect to this Indenture or the Notes only if:

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

          (2) Holders of at least 25% in aggregate principal amount of the then outstanding Notes
make a written request to the Trustee to pursue the remedy;

          (3) such Holder or Holders offer and, if requested, provide to the Trustee security or
indemnity reasonably satisfactory to the Trustee against any loss, liability or expense;

          (4) the Trustee does not comply with the request within 60 days after receipt of the
request and the offer of security or indemnity; and

          (5) during such 60-day period, Holders of a majority in aggregate principal amount of
the then outstanding Notes do not give the Trustee a direction inconsistent with such
request.

     A Holder of a Note may not use this Indenture to prejudice the rights of another Holder of a
Note or to obtain a preference or priority over another Holder of a Note.

     The Issuers and the Guarantors are required to deliver to the Trustee annually a statement
regarding compliance with this Indenture. Upon becoming aware of any Default or Event of Default,
the

66

 

Issuers and the Guarantors are required to deliver to the Trustee a statement specifying such
Default or Event of Default.

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 Liquidated Damages, if any, and interest 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 is authorized to recover judgment in its own name and as trustee of an
express trust against the Issuers for the whole amount of principal of, premium and Liquidated
Damages, if any, and interest remaining unpaid on, the Notes and interest on overdue principal and,
to the extent lawful, interest and such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

Section 6.09 Trustee May File Proofs of Claim.

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

Section 6.10 Priorities.

     If the Trustee collects any money pursuant to this Article 6, it shall pay out the money
in the following order:

          First: to the Trustee, its agents and attorneys for amounts due under Section 7.07
hereof, including payment of all compensation, expenses and liabilities incurred, and all
advances made, by the Trustee and the costs and expenses of collection;

67

 

          Second: to Holders of Notes for amounts due and unpaid on the Notes for principal,
premium and Liquidated Damages, if any, and interest, ratably, without preference or
priority of any kind, according to the amounts due and payable on the Notes for principal,
premium and Liquidated Damages, if any and interest, respectively; and

          Third: to the Issuers or to such party as a court of competent jurisdiction shall
direct.

     The Trustee may fix a record date and payment date for any payment to Holders of Notes
pursuant to this Section 6.10.

Section 6.11 Undertaking for Costs.

     In any suit for the enforcement of any right or remedy under this Indenture or in any
suit against the Trustee for any action taken or omitted by it as a Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an undertaking to pay the
costs of the suit, and the court in its discretion may assess reasonable costs, including
reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits
and good faith of the claims or defenses made by the party litigant. This Section 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 than 10% in aggregate principal amount of the then outstanding Notes.

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;

68

 

          (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.

       (d) Whether or not therein expressly so provided, every provision of this
Indenture that in any way relates to the Trustee is subject to 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.

Section 7.02 Rights of Trustee.

       (a) The Trustee may conclusively rely upon any document believed by it to be genuine
and to have been signed or presented by the proper Person. The Trustee need not investigate any
fact or matter stated in the document.

       (b) Before the Trustee acts or refrains from acting, it may require an Officers’
Certificate or an Opinion of Counsel or both. The Trustee will not be liable for any action it
takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of
Counsel. The Trustee may consult with counsel and the written advice of such counsel or any
Opinion of Counsel will be full and complete authorization and protection from liability in
respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance
thereon.

       (c) The Trustee may act through its attorneys and agents and will not be
responsible for the misconduct or negligence of any agent appointed with due care.

       (d) The Trustee will not be liable for any action it takes or omits to take in
good faith that it believes to be authorized or within the rights or powers conferred upon it by
this Indenture.

       (e) Unless otherwise specifically provided in this Indenture, any demand, request,
direction or notice from the Issuers will be sufficient if signed by an Officer of each of the
Issuers.

       (f) The Trustee will be under no obligation to exercise any of the rights or
powers vested in it by this Indenture at the request or direction of any of the Holders unless
such Holders have 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

69

 

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 or Liquidated Damages, if any, or interest on, any Note, the Trustee may
withhold the notice if and so long as a committee of its Responsible Officers in good faith
determines that withholding the notice is in the interests of the Holders of the Notes.

Section 7.06 Reports by Trustee to Holders of the Notes.

       (a) Within 60 days after each May 15 beginning with the May 15 following the date of
this Indenture, and for so long as Notes remain outstanding, the Trustee will 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.

       (b) The Issuers and the Guarantors will indemnify the Trustee against any and all
losses, liabilities or expenses incurred by it arising out of or in connection with the
acceptance or administration of its duties under this Indenture, including the costs and expenses
of enforcing this Indenture against the Issuers and the Guarantors (including this Section 7.07)
and defending itself against any claim (whether asserted by the Issuers, the Guarantors, any
Holder or any other Person) or

70

 

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(7) or (8) hereof occurs, the expenses and the compensation for the
services (including the fees and expenses of its agents and counsel) are intended to constitute
expenses of administration under any Bankruptcy Law.

       (f) The Trustee will comply with the provisions of TIA § 313(b)(2) to the extent
applicable.

Section 7.08 Replacement of Trustee.

       (a) A resignation or removal of the Trustee and appointment of a successor Trustee will
become effective only upon the successor Trustee’s acceptance of appointment as provided in this
Section 7.08.

       (b) The Trustee may resign in writing at any time and be discharged from the trust
hereby created by so notifying the Issuers. The Holders of a majority in aggregate principal
amount of the then outstanding Notes may remove the Trustee by so notifying the Trustee and the
Issuers in writing. The Issuers may remove the Trustee if:

          (1) the Trustee fails to comply with Section 7.10 hereof;

          (2) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is
entered with respect to the Trustee under any Bankruptcy Law;

          (3) a custodian or public officer takes charge of the Trustee or its property; or

          (4) the Trustee becomes incapable of acting.

       (c) If the Trustee resigns or is removed or if a vacancy exists in the office of
Trustee for any reason, the Issuers will promptly appoint a successor Trustee. Within one year
after the successor Trustee takes office, the Holders of a majority in aggregate principal amount
of the then outstanding Notes may appoint a successor Trustee to replace the successor Trustee
appointed by the Issuers.

       (d) If a successor Trustee does not take office within 60 days after the retiring
Trustee resigns or is removed, the retiring Trustee, the Issuers, or the Holders of at least 10%
in aggregate principal

71

 

amount of the then outstanding Notes may petition any court of competent
jurisdiction for the appointment of a successor Trustee.

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

       (f) A successor Trustee will deliver a written acceptance of its appointment to
the retiring Trustee and to the Issuers. Thereupon, the resignation or removal of the retiring
Trustee will become effective, and the successor Trustee will have all the rights, powers and
duties of the Trustee under this Indenture. The successor Trustee will 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

ARTICLE 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

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

Section 8.02 Legal Defeasance and Discharge.

72

 

     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 or premium and Liquidated Damages, 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(6) inclusive hereof will not constitute Events of Default.

73

 

Section 8.04 Conditions to Legal or Covenant Defeasance.

     In order to exercise either Legal Defeasance or Covenant Defeasance under either Section
8.02 or 8.03 hereof:

          (1) the Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of
the Holders of the Notes, cash in U.S. dollars, non-callable Government Securities, or a
combination of cash in U.S. dollars and non-callable Government Securities, in amounts as
will be sufficient, in the opinion of a nationally recognized investment bank, appraisal
firm or firm of independent public accountants, to pay the principal of, or interest and
premium and Liquidated Damages, 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 date of this Indenture, there has been a change in the applicable
federal income tax law,

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

          (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;

          (5) such Legal Defeasance or Covenant Defeasance will not result in a breach or
violation of, or constitute a default under, any material agreement or instrument (other
than this Indenture) to which Holly Energy Partners or any of its Subsidiaries is a party or
by which Holly Energy Partners or any of its Subsidiaries is bound;

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

74

 

          (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 and Liquidated Damages, if any, and interest, but such money need not be segregated from
other funds except to the extent required by law.

     The Issuers will pay and indemnify the Trustee against any tax, fee or other charge imposed on
or assessed against the cash or non-callable Government Securities deposited pursuant to Section
8.04 hereof or the principal and interest received in respect thereof other than any such tax, fee
or other charge which by law is for the account of the Holders of the outstanding Notes.

     Notwithstanding anything in this Article 8 to the contrary, the Trustee will deliver or pay to
the Issuers from time to time upon the request of the Issuers any money or non-callable Government
Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof), are in
excess of the amount thereof that would then be required to be deposited to effect an equivalent
Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to the Issuers.

     Any money deposited with the Trustee or any Paying Agent, or then held by the Issuers, in
trust for the payment of the principal of, premium or Liquidated Damages, if any, or interest on,
any Note and remaining unclaimed for two years after such principal, premium or Liquidated Damages,
if any, or interest has become due and payable shall be paid to the Issuers on their request or (if
then held by the Issuers) will be discharged from such trust; and the Holder of such Note will
thereafter be permitted to look only to the Issuers for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuers as
trustee thereof, will thereupon cease; provided, however, that 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

75

 

8.02 or 8.03 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case
may be; provided, however, that, if the Issuers make any payment of principal of, premium or
Liquidated Damages, if any, or interest on, any Note following the reinstatement of its
obligations, the Issuers will be subrogated to the rights of the Holders of such Notes to receive
such payment from the money held by the Trustee or Paying Agent.

ARTICLE 9

AMENDMENT, SUPPLEMENT AND WAIVER

Section 9.01 Without Consent of Holders of Notes.

     Notwithstanding Section 9.02 of this Indenture, the Issuers, the Guarantors and the
Trustee may amend or supplement this Indenture or the Notes or the Note Guarantees without the
consent of any Holder of Note:

          (1) to cure any ambiguity, defect or inconsistency;

          (2) to provide for uncertificated Notes in addition to or in place of certificated
Notes;

          (3) to provide for the assumption of the Issuers’ or a Guarantor’s obligations to the
Holders of the Notes and Note Guarantees in the case of a merger or consolidation or sale of
all or substantially all of the Issuers’ or such Guarantors’ assets, as applicable;

          (4) to make any change that would provide any additional rights or benefits to the
Holders of the Notes or that does not adversely affect the legal rights hereunder of any
such Holder;

          (5) to comply with requirements of the SEC in order to effect or maintain the
qualification of this Indenture under the TIA;

          (6) to conform the text of this 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 this Indenture or
the Note Guarantees;

          (7) to provide for the issuance of Additional Notes in accordance with the limitations
set forth in this Indenture as of the date hereof;

          (8) to allow any Guarantor to execute a supplemental indenture and/or a Note Guarantee
with respect to the Notes or to reflect the release of a Note Guarantee in accordance with
this Indenture;

          (9) to secure the Notes and/or the Note Guarantees; or

          (10) to provide for the reorganization of Holly Energy Partners as any other form of
entity, in accordance with Section 5.01(a).

     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 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 any amended or supplemental indenture authorized or
permitted by the terms of this Indenture and to make any further appropriate agreements and
stipulations that may be

76

 

therein contained, but the Trustee will not be obligated to enter into such amended or supplemental indenture that affects its own rights, duties or immunities under this
Indenture or otherwise.

Section 9.02 With Consent of Holders of Notes.

     Except as provided below in this Section 9.02, the Issuers and the Trustee may amend or
supplement this Indenture (including, without limitation, Sections 3.09, 4.10 and 4.15 hereof) and
the Notes and the Note Guarantees with the consent of the Holders of at least a majority in
aggregate principal amount of the then outstanding Notes (including, without limitation, Additional
Notes, if any) voting as a single class (including, without limitation, consents obtained in
connection with a tender offer or exchange offer for, or purchase of, the Notes), and, subject to
Sections 6.04 and 6.07 hereof, any existing Default or Event of Default (other than a Default or
Event of Default in the payment of the principal of, premium or Liquidated Damages, if any, or
interest on, the Notes, except a payment default resulting from an acceleration that has been
rescinded) or compliance with any provision of this 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, without limitation, Additional Notes, if any) voting as a single
class (including, without limitation, consents obtained in connection with a tender offer or
exchange offer for, or purchase of, the Notes). Section 2.08 hereof shall determine which Notes
are considered to be “outstanding” for purposes of this Section 9.02.

     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 Issures 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 (other than provisions relating to
Sections 4.10 or 4.15 hereof);

77

 

          (3) reduce the rate of or change the time for payment of interest, including default
interest, on any Note;

          (4) waive a Default or Event of Default in the payment of principal of, or interest or
premium or Liquidated Damages, if any, 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
or premium or Liquidated Damages, 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 and thereafter binds every Holder.

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.

78

 

     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 and Liquidated Damages, if any, and interest 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 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.

79

 

       (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.

     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.

80

 

     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
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)

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

     (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;
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 premium and
Liquidated Damages, 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
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 and Liquidated Damages, if any, and accrued interest to the date of
maturity or redemption;

          (2) no Default or Event of Default has occurred and is continuing on the date of such
deposit (other than a Default or Event of Default resulting from the borrowing of funds to
be applied to such deposit) and the 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;

82

 

          (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 an Officers’ Certificate and an Opinion of Counsel to the
Trustee stating that all conditions precedent to satisfaction and discharge have been satisfied.

     Notwithstanding the satisfaction and discharge of this 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 Liquidated Damages, 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 or Liquidated Damages,
if any, or interest 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.

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, 2005. 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 installments of interest and
Liquidated Damages, if any, (without regard to any applicable grace periods) from time to
time on demand 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 Liquidated Damages, 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
Liquidated Damages, 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 Liquidated Damages, 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 Liquidated Damages, if any, on, all Global Notes and all other
Notes the Holders of which will have provided wire transfer instructions to the Issuers or
the Paying Agent. 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

A-2

 

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
February 28, 2005 (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 as set forth in subparagraphs (b) and (c) of this Paragraph 5, the
Issuers will not have the option to redeem the Notes prior to March 1, 2010. On or after March
1, 2010, 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 Liquidated Damages, 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
	2010

	 	 	103.125	%
	2011

	 	 	102.833	%
	2012

	 	 	101.042	%
	2013 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.

     Notwithstanding the provisions of subparagraph (a) of this Paragraph 5, at any time prior to
March 1, 2008, 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 the Indenture at a
redemption price of 106.250% of the principal amount, plus accrued and unpaid interest and
Liquidated Damages, 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 the 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, 2010, the Issuers may also redeem all or a part of the Notes, upon not
less than 30 nor more 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 Liquidated Damages, 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.

A-3

 

     For purposes of this Paragraph 5, “Applicable Premium” means, with respect to any Note on any
redemption date, the greater of (1) 1.0% 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,
2010 (such redemption price being set forth in the table appearing in subparagraph (a)) plus (ii)
all required interest payments due on the Note through March 1, 2010 (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.
In addition, for purposes of this Paragraph 5, “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, 2010;
provided, however, that if the period from the redemption date to March 1, 2010, 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.

     Except as set forth below, 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 $1,000 or
an integral multiple 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
Liquidated Damages, 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 $20.0 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
Liquidated Damages, 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 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

A-4

 

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 $1,000 may be redeemed in part but only in whole multiples of $1,000, unless all of the
Notes held by a Holder are to be redeemed.

     (9) Denominations, Transfer, Exchange. The Notes are in registered form without
coupons in denominations of $1,000 and integral multiples of $1,000. 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 date of the Indenture, to secure the Notes and/or the Note Guarantees, 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, or Liquidated Damages, if any, with respect to the
Notes; (ii) default in the payment when due (at maturity, upon redemption or otherwise) of
the principal

A-5

 

of, or premium, if any, on 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 or any of its Restricted Subsidiaries for 60 days after written notice
to comply with any of the other agreements in the Indenture; (v) default under certain other
agreements relating to Indebtedness of the Issuers which default results in the acceleration
of such Indebtedness prior to its express maturity; (vi) certain final judgments for the
payment of money that remain undischarged for a period of 60 days; (vii) 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 (viii)
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 or premium or Liquidated Damages, if any. The Holders of a majority in aggregate
principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of
the Holders of all of the Notes, rescind an acceleration or waive any existing Default or
Event of Default and its consequences under the Indenture except a continuing Default or
Event of Default in the payment of interest or premium or Liquidated Damages, 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 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.

     (15) Authentication. This Note will not be valid until authenticated
by the manual signature of the Trustee or an authenticating agent.

Committee on Uniform Security Identification Procedures, the Issuers have caused CUSIP
numbers to be printed on the Notes, and the Trustee may use CUSIP numbers in notices of
redemption as a convenience to Holders. No representation is made as to the accuracy of
such numbers either as printed on the Notes or as contained in any notice of redemption, and
reliance may be placed only on the other identification numbers placed thereon.

CONSTRUE THE INDENTURE, THIS NOTE AND THE NOTE GUARANTEES.

[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 February 28, 2005 providing for the issuance of 6-1/4% Senior Notes due
2015 (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.
