Assets and the adjusted tax basis of the Contributed Assets will be taken into
account under the "remedial method" as described in Treasury Regulation Section
1.704-3(d). Transferee and the Transferor Parties further agree that they shall
report the federal, state, municipal, local and other Tax consequences of the
contribution and acquisition hereunder in a manner consistent with this Section
1.8 and they shall not take any position inconsistent therewith in connection
with any Tax return, refund claim, litigation or otherwise. The parties hereby
acknowledge that none of the parties has made, or is making in this Agreement,
any representation to any other party concerning any of the Tax effects or
consequences of the transactions provided for in this Agreement and that each
party has obtained

            (a)   Material Casualty. Transferors shall notify Transferee in
writing on the next business day, and in no event later than 24 hours, if, after
the date of this Agreement and prior to the Closing, all or any part of a
Pipeline and Terminal Asset is damaged or destroyed by fire or other casualty
and such damage or destruction, individually or in the aggregate, constitutes a
Material Damage or Condemnation. Transferee shall have the option, exercisable
within ten days after receipt of such written notice from Transferors (but
before Closing), to elect

                                       12

by written notice to Transferors to terminate this Agreement; provided, however,
that such election by Transferee to terminate this Agreement shall not be
effective if:

                  (i)   such damaged or destroyed Pipeline and Terminal Asset
can be repaired or replaced to the state in which such asset existed immediately
preceding such damage or destruction within 120 days from the date of
Transferors' receipt of Transferee's notice of termination; and

                  (ii)  within ten days after Transferors' receipt of
Transferee's notice of termination, Transferors give Transferee written notice
of Transferors' election to repair or replace such damaged or destroyed Pipeline
and Terminal Asset at Transferors' sole expense (including any insurance
proceeds attributable thereto under insurance policies of Transferors or any of
their respective affiliates).

If Transferors elect to repair or replace such damaged Pipeline and Terminal
Asset pursuant to the foregoing, Transferors shall be obligated to proceed in
good faith to diligently repair or replace such damaged or destroyed Pipeline
and Terminal Asset to the state in which such asset existed immediately
preceding such damage or destruction and the Closing Date shall be extended
until the third business day following the date on which Transferors and
Transferee mutually agree that such damaged Pipeline and Terminal Asset has been
so repaired or replaced, such mutual agreement not to be unreasonably withheld,
conditioned or delayed; provided, however, this Agreement shall terminate, at
Transferee's option, if such damaged asset is not so repaired or replaced by the
earlier of (x) 120 days from the date of Transferor's receipt of Transferee's
aforesaid notice of termination or (y) the Termination Date.

            (b)   Material Condemnation. Transferors shall notify Transferee in
writing on the next business day, and in no event later than 24 hours, if, after
the date of this Agreement and prior to the Closing, all or any part of a
Pipeline and Terminal Asset is taken in condemnation or if proceedings for such
purpose shall be pending, and such taking, individually or in the aggregate,
constitutes or would constitute a Material Damage or Condemnation. Transferee
shall have the option, exercisable within ten days following receipt of such
written notice from Transferors (but before Closing), to elect by written notice
to Transferors to terminate this Agreement.

            (c)   Other Casualty and Condemnation. If after the date of this
Agreement and prior to the Closing:

                  (i)   all or any part of a Pipeline and Terminal Asset shall
be damaged or destroyed by fire or other casualty and either (A) such damage or
destruction does not, individually or in the aggregate, constitute a Material
Damage or Condemnation or (B) Transferee does not elect to terminate this
Agreement pursuant to Section 2.4(a); or

                  (ii)  all or any part of a Pipeline and Terminal Asset shall
be taken in condemnation or under the right of eminent domain or if proceedings
for such purposes shall be pending and either (A) such taking does not,
individually or in the aggregate, constitute a

                             CONTRIBUTION AGREEMENT

                                       13
<PAGE>

Material Damage or Condemnation or (B) Transferee does not elect to terminate
this Agreement pursuant to Section 2.4(b);

then this Agreement shall remain in full force and effect notwithstanding any
such damage, destruction, taking or proceeding or the threat thereof.

            (d)   Insurance Proceeds, Condemnation Awards or Other Proceeds. To
the extent insurance proceeds (excluding any insurance proceeds payable through
self-insurance programs of Transferors or their respective affiliates),
condemnation awards or other payments are not committed, used or applied by
Transferors prior to the Closing Date to repair, restore or replace such
damaged, destroyed or taken Pipeline and Terminal Asset, Transferors shall at
the Closing (i) assign to Transferee Transferors' rights to receive all
insurance or condemnation proceeds, awards or payments (excluding any insurance
proceeds payable through self-insurance programs of Transferors or their
respective affiliates) owed to Transferors in respect of such Pipeline and
Terminal Asset by reason of such damage, destruction or taking, less any
reasonable costs and expenses incurred by Transferors in collecting same or in
connection with such proceedings or the threat thereof, and (ii) pay to
Transferee all insurance or condemnation proceeds, awards or payments (excluding
any insurance proceeds payable through self-insurance programs of Transferors or
their respective affiliates) theretofore paid to Transferors in respect of such
Pipeline and Terminal Asset by reason of such damage, destruction or taking,
less any reasonable costs and expenses incurred by Transferors in collecting
same or in connection with such proceedings or the threat thereof. Further, to
the extent Transferors do not repair, restore or replace any such damaged or
destroyed Pipeline and Terminal Asset at least substantially to the condition in
which such asset existed prior to such damage or destruction (taking into
account the age of any individual asset and its use, if any, in the Operations
immediately prior to such damage or destruction), and any insurance proceeds
paid to Transferee pursuant to Section 2.4(c) are insufficient to cover the
diminution in value of such damaged or destroyed Pipeline and Terminal Asset
resulting from such damage or destruction and Transferors' failure to repair,
restore or replace the same as provided above, then the Cash Consideration shall
be reduced by the amount of such deficiency as shall be mutually agreed by
Transferee and Transferors in good faith (such amount, the "Deficiency Amount").

      2.5 PRORATIONS. On the Closing Date, or as promptly as practicable
following the Closing Date, but in no event later than 60 calendar days
thereafter, the real and personal property Taxes, water, gas, electricity and
other utilities, local business or other license fees to the extent assigned and
other similar periodic charges payable with respect to the Contributed Assets
shall be prorated between Transferee, on the one hand, and Transferors, on the
other hand, effective as of the Effective Time with Transferors being
responsible for amounts related to the period prior to but excluding the
Effective Time and Transferee being responsible for amounts related to the
period at and after the Effective Time. The Parties shall take all actions
necessary to cause utility meter readings to be determined as of the Effective
Time or as close thereto as reasonably practicable. If the final real property
Tax rate or final assessed value for the current Tax year is not established by
the Closing Date, the prorations shall be made on the basis of the rate or
assessed value in effect for the preceding Tax year and shall be adjusted when

                           HOLLY ENERGY PARTNERS, L.P.
                             CONTRIBUTION AGREEMENT

                                       14
<PAGE>

the exact amounts are determined. All such prorations shall be based upon the
most recent available assessed value available prior to the Closing Date.

      2.6 CLOSING COSTS; TRANSFER TAXES AND FEES.

            (a)   Allocation of Costs. Transferee shall pay the cost of all
sales, transfer and use Taxes arising out of the transfer of the Contributed
Assets pursuant to this Agreement and, subject to Section 2.2(k), all costs and
expenses (including recording fees and real estate transfer Taxes and real
estate transfer stamps) incurred in connection with obtaining or recording title
to the Contributed Assets. The sales, use and transfer Tax returns required by
reason of said transfer shall be timely prepared and filed by the party normally
obligated by Law or regulation to make such filing. Transferors and Transferee
agree to cooperate with each other in connection with the preparation and filing
of such returns, in obtaining all available exemptions from such sales, use and
transfer Taxes, and in timely providing each other with resale certificates and
any other documents necessary to satisfy any such exemptions.

            (b)   Reimbursement. If Transferee, on the one hand, or any
Transferor, on the other hand, pays any Tax agreed to be borne by the other
party under this Agreement, such other party shall promptly (within five
business days) reimburse the paying party for the amounts so paid. If any party
receives any Tax refund or credit applicable to a Tax paid by another party
hereunder, the receiving party shall promptly (within five business days) pay
such amounts to the party entitled thereto.

            (c)   Agreement Regarding Records. Prior to Closing, Transferee and
Transferors shall identify those records and documents that shall constitute a
part of the Records. On or before the 60th day following the Closing,
Transferors shall provide originals of the applicable records and documents to
Transferee to the extent Transferors or their respective affiliates have such
originals in their possession. Transferors shall deliver any records and
documents that constitute a part of the Records that are discovered by
Transferors to be in their possession or the possession of any of their
respective affiliates after the date on which the Records are delivered to
Transferee pursuant to the provisions hereof.

as set forth in Transferor Disclosure Schedule 3.3, the execution, delivery and
performance by each Alon Party and Newco 1 of this Agreement and the other Alon

Transferors, Newco 1 will hold, all permits, licenses, variances, exemptions,
orders, franchises and approvals of all Governmental Entities necessary for the
lawful ownership or material to the operation of the Pipeline and Terminal
Assets and the conduct of the Operations (the "Permits") and (b) the Operations
comply with, and the Transferors and their respective affiliates have owned and

the knowledge of the Alon Parties, threatened which, if resolved adversely to
such Transferor or any of its affiliates, could reasonably be expected to have a
Material Adverse Effect. For purposes of this Section 3.4, the term "applicable
Laws," as used in clause (a) above, shall not include any Environmental Laws or

            (a)   Operating Statements. Transferors have provided to Transferee

occurred that would have violated the terms of Sections 5.1(d), 5.1(i), 5.1(l)
and 5.1(m) hereof if the terms thereof had been in effect from and after
December 31, 2004.

      3.7 TITLE TO CONTRIBUTED ASSETS.

            (a)   Except as set forth on Transferor Disclosure Schedule 3.7(a),
Transferors have, and at the Closing Newco 1 shall receive and own, good and
marketable title to the Fee Land and all of the Contributed Assets that

and clear of any Liens, other than Permitted Liens.

            (b)   Each tract of Fee Land is owned in fee simple by the
applicable Transferor, subject only to the Permitted Liens, and except as set
forth on Transferor Disclosure Schedule 3.7(b), none of the Fee Land is subject
to any lease or other possessory interest of any person other than the
applicable Transferor. Except for the Leases, and except as described in
Transferor Disclosure Schedule 3.7(b), Transferors do not lease any parcels,
tracts of land, buildings, fixtures or improvements that are used or held for
use primarily in connection with the Operations.

            (c)   Except as set forth in Transferor Disclosure Schedule 3.7(c),
the Real Property constitutes all the parcels, tracts of land, buildings,
fixtures and improvements that are used or held for use primarily in connection
with the Operations.

            (d)   Except as set forth in Transferor Disclosure Schedule 3.7(d),

Improvements located on the Real Property and all such Permits have been paid
for and are in full force and effect. Except as set forth on Transferor
Disclosure Schedule 3.7(d), no commitments have been made to any Governmental
Entity, utility company, school board, church or other religious body or any
homeowners or homeowners' association, or any other organization, group or
individual, relating to the Real Property that would impose an obligation on
Transferee, its affiliates or their respective successors or assigns to make any
contribution or dedications of money or land or to construct, install or
maintain any improvements of a public or private nature on or off of the Real

Property. Except as set forth on Transferor Disclosure Schedule 3.7(d), since
December 31, 2004 the Improvements have been maintained in accordance with
historical practices (but in no event at less than prudent industry standards
and practices), other than deferred maintenance projects set forth on Transferor
Disclosure Schedule 3.7(d) or deferred maintenance projects that, individually
or in the aggregate, do not exceed $50,000. To the knowledge of the Alon
Parties, the compliance in all respects of the Real Property and all aspects
thereof with all applicable zoning and similar Laws does not depend on, and no
Operating Permit for such real property depends on, any other real property or
other rights appurtenant thereto.

            (e)   Each parcel of Real Property is adequately serviced by all
public utilities and services, including electricity, water, sewage and
telecommunications, to the extent necessary to continue the operation of the
Contributed Assets located thereon consistent with operation by the applicable
Transferor prior to the date of this Agreement.

            (f)   Except as provided in Transferor Disclosure Schedule 3.7(f),

sale, conveyance, transfer, lease or disposition of any portion of the Real
Property (except for this Agreement or as contemplated hereby); (ii) there has
not been granted to any person and no person possesses, any option to purchase
or right of first refusal to purchase any portion of the Real Property; and

            (g)   Except as set forth in Transferor Disclosure Schedule 3.7(g),
(i) no Transferor is in material default under any Easement or Lease to which it
is a party, nor to the knowledge of the Alon Parties, is there any event or
circumstance that solely with the giving of notice or the lapse of time or both
would constitute a material default under any such Easement or Lease, (ii) there
are no easement gaps in the "Trust Pipeline" or the "River Pipeline," and to the
knowledge of the Alon Parties, the "Fin-Tex Pipeline" and (iii) the Easements
are in full force and effect and are sufficient to allow the applicable
Transferor and Newco 1 to continue to operate the Pipelines therein or thereon
(without interruption) as currently operated. All Pipelines are located fully
within the land constituting or encumbered by the Pipeline Easements. All
Easements and Leases represent valid, binding and enforceable agreements of the
applicable Transferor and, to the knowledge of the Alon Parties, each of the
parties thereto and there is no pending modification or cancellation of same.

            (h)   The applicable Transferor has a valid and subsisting leasehold
estate in and the right to quiet enjoyment of the real property leased to it
under the Pipeline Leases and Terminal Leases for the full term thereof, subject

assets or liabilities other than its liabilities and obligations under this
Agreement, and as of the Closing Newco 1 shall have no assets or liabilities
other than the Contributed Assets, Assumed Liabilities and the liabilities and
obligations under this Agreement which it shall hold immediately following the

      3.9 CONTRACTS.

                  (a)   True, correct and complete copies of all Assumed

Disclosure Schedule 3.9(a), (i) each Assumed Contract is in full force and
effect and constitutes a valid and binding agreement, enforceable in accordance
with its terms, of the applicable Transferor and, to the knowledge of the Alon
Parties, each other party thereto, (ii) neither the applicable Transferor nor
any of its affiliates is in breach of or default, in any material respect, under
any Assumed Contract involving or relating to any of the Pipeline and Terminal
Assets, and (iii) to the knowledge of the Alon Parties, there does not exist
under any provision of any Assumed Contract any event that, with the giving of
notice or the lapse of time or both, would constitute such a breach or default
by the applicable Transferor or any of its affiliates under such contract.
Except as disclosed in Transferor Disclosure Schedule 3.9(a), no other party to
any Assumed Contract is, to the knowledge of the Alon Parties, in breach of or
default under such Assumed Contract in any material respect. No Alon Party nor
any affiliate thereof has received any notice from any other party to any
Assumed Contract that alleges any violation, breach or default by any Transferor
of any Assumed Contract in any material respect.

                  (b)   Assuming the Consents set forth on Transferor Disclosure
Schedule 3.3 are obtained prior to Closing, each Assumed Contract shall not be
cancelable by the other party due to the consummation of the transactions
contemplated hereby.

primarily in connection with the Operations is listed in Transferor Disclosure
Schedules 1.1(i), 1.1(j), 1.1(k) and 1.1(l). Transferors own or hold pursuant to

and no Transferor nor any affiliate of any Transferor has granted to any third
party any license or other right to any of such Intellectual Property and no
Transferor is a party to or bound by any Contract or any other obligation
whatsoever that limits or impairs its ability to use, sell, transfer, assign or

Property does not infringe any such rights. To the knowledge of the Alon
Parties, no person is infringing any Transferor's rights in its Intellectual
Property. All registrations and certificates issued by any Governmental Entity

Transferor nor any affiliate of any Transferor has received any communication
alleging such a violation. Except as set forth in Transferor Disclosure Schedule
3.12, no Transferor is obligated to compensate any person for the licensing of
such software products or custom software.

to the date of this Agreement. All such Tax returns are true, correct and
complete in all material respects and the applicable Transferor or an affiliate
of such Transferor has timely paid all Taxes shown as due and payable on all Tax
returns. No Taxing Authority has raised any issues relating to Taxes for which a
Lien could otherwise be imposed after the Closing Date upon any of the
Contributed Assets. Except as set forth in Transferor Disclosure Schedule 3.13,
no audit or other proceeding by any Governmental Entity is pending or, to the
knowledge of the Alon Parties, threatened with respect to any Taxes due or any
Tax return filed by any Transferor or any affiliate of any Transferor relating
to the Pipeline and Terminal Assets or the Operations. No assessment of any Tax
(other than assessments of Taxes not yet due) is proposed against any Transferor
or any of its affiliates relating to any of the Contributed Assets. No
Transferor nor any affiliate of any Transferor has been and is now in violation

                  REPRESENTATIONS AND WARRANTIES OF TRANSFEREE

      Transferee hereby represents and warrants to Transferors as follows:

      4.1 ORGANIZATION. Each Transferee Party is duly organized, validly
existing and in good standing under the Laws of its state of organization and
has the requisite power to own, lease and operate its properties and to carry on
its business as now being conducted. Each Transferee Party is duly qualified to
do business and in good standing as a foreign limited partnership in all
jurisdictions in which the character of the properties now owned or leased by it
or the nature of the business conducted by it requires it to be so licensed or
qualified, except where the failure to be so licensed or qualified would not
materially impair such Transferee Party's ability to consummate the transactions
contemplated by this Agreement.

      4.2 AUTHORIZATION. Each Transferee Party has full power and authority to
(a) execute and deliver this Agreement and the Transferee Ancillary Documents
contemplated hereby to be executed and delivered by such Transferee Party and
(b) consummate the transactions contemplated hereby and thereby. Each Transferee
Party has taken all action required by the organizational documents for such
party (the "Transferee Party Organizational Documents") to authorize (a) the
execution and delivery of this Agreement and the Transferee Ancillary Documents
to be executed and delivered by such Transferee Party and (b) the consummation
of the transactions contemplated hereby and thereby. This Agreement has been
duly and validly executed and delivered by each Transferee Party and is a legal,
valid and binding obligation of each Transferee Party, enforceable against it in
accordance with its terms, except as enforcement may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance or
other similar laws now or hereafter in effect relating to creditors' rights
generally and general principles of equity (regardless of whether enforceability
is considered in a proceeding at law or in equity). All Transferee Ancillary
Documents to be executed and delivered by each Transferee Party shall on the
Closing Date be duly and validly executed by such Transferee Party and be legal,
valid and binding obligations of such Transferee Party, enforceable against it
in accordance with their respective terms, except as may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance or other similar Laws now or hereafter in effect relating to
creditors' rights generally and general principles of equity (regardless of
whether enforceability is considered in a proceeding at law or in equity).

      4.3 NO VIOLATIONS; NO CONSENTS OR APPROVALS REQUIRED. Except as set forth
on Transferee Disclosure Schedule 4.3, the execution, delivery and performance
by each Transferee Party of this Agreement and the Transferee Ancillary
Documents to which it is a party does not, and consummation of the transactions
contemplated hereby and thereby will not, (a) violate, conflict with, or result
in any breach of any provisions of the Transferee Party Organizational
Documents; (b) violate, conflict with or result in a violation or breach of, or
constitute a default (with or without due notice or lapse of time or both)
under, any of the terms, conditions or provisions of any material Contract, or
other instrument or obligation, to which any Transferee Party is a party or by
which any Transferee Party or any material portion of its respective assets is
bound; or (c) subject to obtaining the Consents or making the registrations,
declarations or

                           HOLLY ENERGY PARTNERS, L.P.

filings set forth in the next sentence, violate any applicable Law binding upon
any Transferee Party or by which it or any material portion of its assets are
bound, except, with respect to clauses (b) and (c), such violations, conflicts,
breaches or defaults as would not materially impair the ability of any
Transferee Party to perform its obligations under this Agreement and the
Transferee Ancillary Documents to which it is a party. No Consent of any
Governmental Entity or any other person is required for Transferee in connection
with the execution, delivery and performance of this Agreement and the other
Ancillary Documents to which it is a party or the consummation of the
transactions contemplated hereby and thereby, except for (i) requirements under
the HSR Act, (ii) Post-Closing Consents, and (iii) such other Consents, the
failure of which to obtain would not materially impair the ability of the
applicable Transferee Party to perform its obligations under this Agreement and
the other Ancillary Documents to which it is or will be a party. Transferee has
obtained commitment letters from nationally recognized financing sources (whose
identity has been previously disclosed to the Alon Parties) that provide for
lending facilities in an amount up to $245,000,000 which facilities are
sufficient to provide the financing necessary for the transactions contemplated
by this Agreement including, if necessary, the refinancing of Transferee's
existing credit facility.

      4.4 ABSENCE OF LITIGATION. There is no Action pending or, to the knowledge
of the Transferee Parties, threatened against any Transferee Party or any of its
affiliates relating to the transactions contemplated by this Agreement or which,
if adversely determined, would materially impair the ability of the Transferee
Parties to perform their obligations and agreements under this Agreement and the
Transferee Ancillary Documents to which they are or will be parties and to
consummate the transactions contemplated hereby and thereby.

      4.5 VALIDITY OF CLASS B UNITS. At the Closing, the Class B Units and the
limited partner interests represented thereby will be duly and validly
authorized by the applicable Transferee Party Organizational Documents and, when
issued and delivered to Newco 2 in accordance with the terms of this Agreement,
will be validly issued, fully paid (to the extent required under the Transferee
Party Organizational Documents) and nonassessable (except as such
nonassessability may be affected by Section 17-607 of the Delaware Revised
Uniform Limited Partnership Act).

      4.6 TRANSFEREE PUBLIC DOCUMENTS. Transferee has filed with the SEC all
material reports, schedules, forms, statements and other documents required by
the Exchange Act (collectively, and in each case including all exhibits and
schedules thereto and documents incorporated by reference therein, the
"Transferee Public Documents"). As of their respective dates, except to the
extent revised or superseded by a subsequent filing with the SEC, the Transferee
Public Documents complied in all material respects with the requirements of the
Securities Act or the Exchange Act, as the case may be, and none of the
Transferee Public Documents (including any and all financial statements included
therein) as of such dates contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. The consolidated financial statements of
Transferee included in all Transferee Public Documents, including any amendments
thereto, when filed, complied as to form in all material respects with
applicable accounting requirements and the published rules and regulations of
the SEC with respect thereto, and fairly presented in

authorized to act on behalf of Transferee who is entitled to receive from the
Transferor Parties any fee or commission in connection with the transactions
contemplated by this Agreement.

a due and timely fashion;

            (e)   prior to the Closing, such Transferor shall give all notices
and shall use all reasonable efforts to obtain all Consents described in
Transferor Disclosure Schedule 3.3 (except the "Railroad License Agreements"
identified therein) from all Governmental Entities or third parties;

            (f)   such Transferor shall not, and shall cause its affiliates not
to, make any amendment to, terminate or fail to use reasonable efforts to renew
any Assumed Contract, or waive, amend or terminate any rights of substantial
value relating to the Contributed Assets;

            (g)   such Transferor shall not, and shall cause its affiliates not
to, fail to maintain each Contributed Asset in a condition at least commensurate
with the current condition thereof;

                  (ii) Subject to clause (iv), the applicable Transferor shall,
at the request and under the direction of Transferee, take all such actions and
do all such things, at Transferor's expense, as shall in the opinion of

of the applicable Transferor under such Rights may be performed in a manner such
that the value of the Rights shall be preserved and shall inure to the benefit
of Newco 1 and such that all such Rights may be received by Newco 1;

                  (iii) the applicable Transferor shall promptly tender over to

Transferors and Transferee shall reasonably cooperate with each other in
obtaining such consents and shall keep each other reasonably informed of the
status of and any developments with respect to obtaining such consents.

      5.8 INSURANCE. With respect to any loss, liability or damage relating to,
resulting from or arising out of the conduct of the Operations on or prior to
the Closing and that constitutes an Assumed Liability and as to which
Transferors would be entitled to assert, or cause any of their respective
affiliates or any other person or entity to assert, a claim for recovery under
any policy of insurance maintained by or for the benefit of Transferors or any
of their respective affiliates thereof in respect of the Contributed Assets, at
the request of Transferee, each Alon Party will use its commercially reasonable
efforts to assert, or to assist Transferee or Newco 1 in asserting, one or more
claims under such insurance covering such loss, liability or damage if
Transferee or Newco 1 is not itself entitled to assert such claim and any Alon
Party or any of its affiliates or other person is so entitled. Any recovery
received by any Alon Party or any of its affiliates or such other person as a
result of any such assertion shall be promptly paid to Newco 1. Transferee
agrees to pay or assume all costs or liabilities of any Alon Party or any of its
affiliates in connection with any such assertion of any such claim, including
legal expenses, deductibles, retentions or self-insurance paid or incurred by
any Alon Party or any of its affiliates. Transferee agrees to cooperate, and to
cause Newco 1 to cooperate, with any Alon Party or any of its affiliates in
connection with any assertion of claims under insurance as contemplated by this
Section 5.8.

      5.9 COOPERATION. Each Alon Party shall cooperate with Transferee and
assist Transferee in identifying all licenses, authorizations, permissions or
Permits necessary to own and operate the Pipeline and Terminal Assets and
conduct the Operations from and after the Closing Date and, where permissible,
transfer existing Permits to Newco 1, or, where not permissible, assist Newco 1
in obtaining new Permits for Transferee at no cost, fee or liability to such
Alon Party.

      5.10 ADDITIONAL AGREEMENTS. Subject to the terms and conditions of this
Agreement, each of the parties shall use its commercially reasonable efforts to
do, or cause to be taken all action and to do, or cause to be done, all things
necessary, proper, or advisable under applicable Laws to consummate and make
effective the transactions contemplated by this Agreement, including the
fulfillment of the conditions set forth in Article VII to the extent that the
fulfillment of such conditions are within the control of such party; provided,
however, that in no event shall Transferee or its affiliates be required to
divest any interest that they may have in any material assets or business. In
furtherance of the foregoing, the Alon Parties and Transferee agree, at or prior
to Closing, to execute and deliver (a) all documents of conveyance, transfer or
assignment which the other party may reasonably request to further evidence or
effectuate the conveyance of all or any portion of the Contributed Assets or the
Newco 1 Equity Interests as contemplated hereby including all such documents
necessary to convey, transfer or assign ownership of Rolling Stock or other
personal property for which ownership is evidenced by title documents or
certificates, and (b) such other documents as the other party may reasonably
request in connection with the consummation of the transactions contemplated
hereby. If at any time after the Closing Date, any further action is necessary
or desirable to carry out the purposes of this Agreement, the parties to this
Agreement and their duly authorized representatives shall use commercially
reasonable efforts to take all such action. Without limiting the generality of
the foregoing, if, after the Closing Date, Newco 1 or its affiliates seek
indemnification or recovery from one or more other parties to an Assumed
Contract or otherwise seek to enforce such Assumed Contract and, to obtain such
indemnification, recovery or enforcement, it is necessary

for a Transferor to initiate a lawsuit, participate in any enforcement
proceeding or otherwise provide assistance to Newco 1 or its affiliates, then,
at the request of Newco 1, and at Newco 1's expense, the Alon Parties shall take
such action as Newco 1 may reasonably request in connection with Newco 1's or
its affiliates' efforts to obtain such indemnification, recovery or enforcement.

      5.11 HSR MATTERS. Transferee and the Alon Parties shall use their
reasonable efforts to (a) obtain all authorizations or waivers required under
the HSR Act to consummate the transactions contemplated hereby, including,
without limitation, making all filings with the Antitrust Division of the DOJ
and the FTC required in connection therewith (the initial filings to occur no
later than ten (10) business days following the execution and delivery of this
Agreement) and (b) respond as promptly as practicable to all inquiries received
from the DOJ or the FTC for additional information or documentation. Transferee
and the Alon Parties shall pay in equal amounts all filing fees associated with
the filing. Each of Transferee and the Alon Parties shall furnish to the other
such necessary information and reasonable assistance as the other may request in
connection with its preparation of any filing that is necessary under the HSR
Act. Transferee and the Alon Parties shall keep each other apprised of the
status of any communications with, and any inquiries or requests for additional
information from, the FTC or the DOJ. In no event shall Transferee or any of its
affiliates, in connection with the consummation of the transactions contemplated
by this Agreement, be required to divest itself of any material assets,
properties or lines of business in order to comply with the requirements of the
HSR Act.

      5.12 ACCESS TO FINANCIAL INFORMATION.

            (a) SEC Letter. Transferee shall use commercially reasonable efforts
to obtain written confirmation from the staff of the SEC that Transferee is not
required to disclose historical financial statements for the Pipeline and
Terminal Assets or the Operations for any period prior to the acquisition
thereof by Transferee under Rule 3-05 of Regulation S-X promulgated under the
Exchange Act.

            (b) Access to Information. To the extent Transferee is unable to
obtain the written confirmation contemplated in Section 5.12(a) within thirty
(30) days from the date of this Agreement, then upon the written request of
Transferee, but only to the extent necessary to comply with Transferee's
disclosure obligations under Rule 3-05 of Regulation S-X, the Alon Parties shall
use commercially reasonable efforts to provide Transferee and its
representatives (including its independent auditors) reasonable access during
normal business hours to such historical financial information (and to those
persons who are responsible for such information) that is necessary to allow
Transferee to prepare the historical financial statements required by Rule 3-05
of Regulation S-X and to enable the audit thereof.

      5.13 BANK CONSENTS. The Alon Parties shall use their commercially
reasonable efforts to obtain the consents of their respective lenders under
their respective revolving credit and term loan agreements to the transactions
contemplated by this Agreement not later than 15 days after the date of this
Agreement, all of which consents are set forth on Schedule 7.3(e) and which
consents shall include an undertaking on the part of such lenders to deliver at

                               EMPLOYMENT MATTERS

      6.1 OFFERS OF EMPLOYMENT.

            (a) On or before the Closing Date, Transferors shall make available
for employment the employees listed on Transferee Disclosure Schedule 6.1(a)
(collectively, the "Material Employees"). Each Transferor acknowledges that
Transferee and its affiliates have no obligation, and have not assumed any
obligation of Transferors, to pay severance or other benefits to such employees
and no such obligations have been or will be assumed by Newco 1.

            (b) Transferee, directly or through one or more of its affiliates,
may extend offers of employment to or otherwise employ any of the Material
Employees or any other employee of Transferors or any affiliate of Transferors
whose employment was terminated by Transferors or such affiliates of Transferors
as a result of or in connection with the transactions contemplated by this
Agreement. Any offers so extended by Transferee shall be on such terms and
conditions that Transferee shall determine in its sole discretion; provided
that, as a whole, the compensation and benefits offered by Transferee shall be
no less favorable than the total compensation and benefits provided to such
employees by the applicable Transferor as of the date of this Agreement.
Transferors acknowledge that neither Transferee nor Newco 1 shall assume any
collective bargaining agreement between Transferors and any collective
bargaining representative. Transferors waive, and Transferors shall cause their
respective affiliates to waive, any claims against Transferee and its affiliates
and any employees of Transferors or their respective affiliates who are extended
an offer of employment by Transferee or its affiliates arising from such
employment by Transferee or its affiliates, including any claims arising under
any employment agreement, confidentiality agreement or non-competition agreement
between such person and Transferors or their respective affiliates.

            (c) The Material Employees who accept offers of employment from
Transferee or its affiliates made prior to the Closing shall hereinafter be
referred to as the "Transferred Employees." All employment offers made to the
Material Employees pursuant to this Section 6.1 shall be made sufficiently in
advance of the Closing so as to give such employees reasonable time to evaluate
the offers (and in no event less than 15 days prior to the Closing Date).

            (d) Effective as of the Closing, Transferee shall use commercially
reasonable efforts to provide, or cause its affiliates to provide, employee
benefits programs for the Transferred Employees that are reasonably comparable
in the aggregate to the employee benefit programs that Transferors and their
ERISA Affiliates maintained for the benefit of such Transferred Employees
immediately prior to the Closing.

<PAGE>

            (e) Transferee shall take such actions as are necessary to ensure
that the Transferred Employees' service with Transferors and Transferors' ERISA
Affiliates completed prior to the Closing ("Past Service") shall be considered
as service with Transferee completed after the Closing for all purposes under
any welfare benefit plan (as defined in Section 3(1) of ERISA) or vacation
policy or sick pay policy maintained by Transferee, or any entity in the same
controlled group of corporations as Transferee or under common control with
Transferee, in which Transferred Employees are eligible to participate.
Transferee shall also take such actions as are necessary to ensure that the
Transferred Employees' Past Service shall be considered as service with
Transferee completed after the Closing for vesting and eligibility purposes, but
for no other purpose, under any pension benefit plan (as defined in Section 3(2)
of ERISA) maintained by Transferee, or any entity in the same controlled group
of corporations as Transferee or under common control with Transferee, in which
Transferred Employees are eligible to participate.

      6.2 TRANSFERORS' EMPLOYEE LIABILITIES.

            (a) Subsequent to the Closing, Transferors shall remain liable for
(i) all accrued but unpaid wages, salary or other compensation, including all
incentive compensation and bonuses, (ii) all vacation benefits and vacation pay,
in each case to the extent that such are deemed owing or otherwise accrued as of
the Effective Time or which are otherwise attributable to the period prior to
the Effective Time, (iii) all severance pay and other amounts or benefits of any
nature due, in respect of employees (including past employees and contract
labor) of Transferors and their respective affiliates, and (iv) all Employee
Benefit Plans and Benefit Arrangements and obligations and liabilities
thereunder.

            (b) Transferors shall be responsible for complying with all Laws and
obligations that may govern the termination of Transferors' employees, including
compliance with any notice requirements of (i) the WARN Act and any similar
state and local plant closing or mass layoff Laws and (ii) any collective
bargaining agreement, in either case regardless of whether such Laws or
agreements impose such requirements on Transferee or Transferors or both; and

            (c) Transferors shall be responsible for providing all employees of
Transferors and other necessary persons such notice and continuation coverage
rights as may be required under Section 4980B of the Code ("COBRA Notice").

not have occurred by April 29, 2005 (the "Termination Date"), provided, however,
that this right to terminate this Agreement shall not be available to any party
whose breach of this Agreement or whose affiliate's breach of this Agreement has
been the cause of, or resulted in, the failure of the Closing to occur on or
before such date;

                  (iv) by either Transferee or Transferors if a Governmental
Entity shall have issued an Order or taken any other action, in each case
permanently restraining, enjoining, or otherwise prohibiting the transactions
contemplated by this Agreement, and such Order or other action shall have become

                  (v) by either Transferee or Transferors in the event of a
breach by the other party of any representation, warranty, covenant or other
agreement contained in this Agreement which (A) would give rise to the failure
of a condition set forth in Sections 7.2(b) or (c) or Sections 7.3(b) or (c), as
applicable, and (B) cannot be or has not been cured within the shorter of (1) 20
days following receipt by the breaching party of written notice of such breach
or (2) the business day immediately preceding the Termination Date (the "Cure
Period").

            (b) Effect of Investigation. The right of any party hereto to
terminate this Agreement pursuant to this Section 8.1 shall remain operative and
in full force and effect regardless of the actual or constructive knowledge of
such party regarding the subject matter giving rise to such right of
termination.

      8.2 EFFECT OF TERMINATION. Upon termination of this Agreement pursuant to
Section 8.1, the undertakings of the parties set forth in this Agreement shall
forthwith be of no further force and effect; provided, however, that this
Section 8.2 and Article XII and rights and remedies for

Department of Transportation and the Environmental Protection Agency (a
"Mechanical Integrity Defect", and such standards, the "Mechanical Integrity
Requirements"); provided, however, that Transferee must have discovered and
notified Transferors of any such failure prior to the first anniversary of the
Closing Date; and provided further, however, that Transferee shall give
Transferors an opportunity to participate in or observe any testing performed

                  (v) the Excluded Assets; or

maintenance projects described in Transferor Disclosure Schedule 3.7(d), Items
6.a, 6.b and 6.c, prior to the Closing; provided, however, that (A) Transferee

complete such deferred projects at their sole cost and expense in accordance
with all legally required standards, (B) if Transferors elect to complete such

Transferee Party (or, if first occurring after the Closing, Newco 1) of any
agreement or covenant of any Transferee Party (or, if first occurring after the
Closing, Newco 1) in this Agreement or any Transferee Ancillary Document; or

                  (iii) any breach of any warranty or the inaccuracy of any
representation of any Transferee Party (or, if first occurring after the

Transferee Closing Certificate or any other certificate delivered hereunder
(without regard to any materiality qualifier contained therein).

      9.2 THIRD PARTY CLAIMS.

            (a) If any Indemnified Party receives written notice of the
commencement of any action or proceeding or the assertion of any claim by a
third party or the imposition of any penalty or assessment for which indemnity
may be sought under this Article IX (a "Third Party Claim"), and such
Indemnified Party intends to seek indemnity pursuant to this Article IX, the
Indemnified Party shall promptly provide the other party (the "Indemnifying
Party") with notice of such Third Party Claim, which notice shall describe such
Third Party Claim in reasonable detail, including all relevant factual
background) and the basis on which the Indemnified Party is entitled to
indemnification hereunder. The Indemnifying Party shall be entitled to
participate in or, at its option, assume the defense, appeal or settlement of
such Third Party Claim. Such defense, appeal or settlement shall be conducted
through counsel selected by the Indemnifying Party and approved by the
Indemnified Party, which approval shall not be unreasonably withheld

or delayed, and the Indemnified Party shall fully cooperate with the
Indemnifying Party in connection therewith. In the event that the Indemnifying
Party notifies the Indemnified Party that the Indemnifying Party will not assume
the defense of such Third Party Claim or otherwise fails to assume the defense
or settlement of any Third Party Claim within 15 days after receipt of notice
thereof, the Indemnified Party shall have the right to undertake the defense,
appeal or settlement of such Third Party Claim at the expense and for the
account of the Indemnifying Party.

            (b) The Indemnified Party shall be entitled, at its own expense, to
participate in the defense of such Third Party Claim; provided, however, that
the Indemnifying Party shall pay the attorneys' fees of the Indemnified Party if
(i) the employment of separate counsel shall have been authorized in writing by
any such Indemnifying Party in connection with the defense of such Third Party
Claim, (ii) the Indemnifying Party shall not have employed counsel reasonably
satisfactory to the Indemnified Party to have charge of such Third Party Claim,
(iii) the Indemnified Party shall have reasonably concluded that there may be
defenses available to such Indemnified Party that are different from or
additional to those available to the Indemnifying Party, or (iv) the Indemnified
Party's counsel shall have advised the Indemnified Party in writing, with a copy
delivered to the Indemnifying Party, that there is a conflict of interest that
could make it inappropriate under applicable standards of professional conduct
to have common counsel.

            (c) The Indemnifying Party shall obtain the prior written approval
of the Indemnified Party (which approval shall not be unreasonably withheld)
before entering into or making any settlement, compromise, admission, or
acknowledgment of the validity of any Third Party Claim or any liability in
respect thereof if, pursuant to or as a result of such settlement, compromise,
admission, or acknowledgment, injunctive or other equitable relief would be
imposed against the Indemnified Party or if, in the opinion of the Indemnified
Party, such settlement, compromise, admission, or acknowledgment could have an
adverse effect on its business, operations, assets or financial condition.

            (d) No Indemnifying Party shall consent to the entry of any judgment
or enter into any settlement that does not include as an unconditional term
thereof the giving by each claimant or plaintiff to each Indemnified Party of a
full and unconditional release from all liability in respect of such Third Party
Claim.

            (e) Notwithstanding Section 9.2(a), the Indemnifying Party shall not
be entitled to control (but shall be entitled to participate at its own expense
in the defense of), and the Indemnified Party shall be entitled to have sole
control over, the defense or settlement, compromise, admission or acknowledgment
of any Third Party Claim (i) as to which the Indemnifying Party fails to assume
the defense within 15 days after receipt of notice thereof or (ii) to the extent
the Third Party Claim seeks an order, injunction or other equitable relief
against the Indemnified Party which, if successful, would adversely affect the
business, operations, assets, or financial condition of the Indemnified Party;
provided, however, that the Indemnified Party shall make no settlement,
compromise, admission, or acknowledgment that would give rise to liability on
the part of any Indemnifying Party without the prior written consent of such
Indemnifying Party.

      9.3 DIRECT CLAIMS.

            (a) Notice of Indemnified Claims. In any case in which an
Indemnified Party seeks indemnification hereunder which is not subject to
Section 9.2 because no Third Party Claim is involved, the Indemnified Party
shall notify the Indemnifying Party in writing of any Losses which such
Indemnified Party claims are subject to indemnification under the terms hereof
(the "Indemnified Claims"). Subject to the limitations otherwise set forth in
this Article IX, the failure of the Indemnified Party to exercise promptness in
such notification shall not amount to a waiver of such claim unless the
resulting delay materially prejudices the position of the Indemnifying Party
with respect to such claim.

            (b) Contested Claims. Each Indemnified Claim shall (i) reference the
indemnity claim to which it relates and shall state the date upon which such
indemnity claim was first asserted; (ii) describe the nature of the Losses
incurred by the Indemnified Party; (iii) describe the reason that the Losses are
recoverable from the Indemnified Party; (iv) state the amount of the Losses; and
(v) provide copies of all available documentation supporting the amount of the
Losses. The Indemnifying Party shall have 30 days following receipt of an
Indemnified Claim to review such claim. The Indemnified Party shall make a
representative reasonably available during this period to respond to any
questions by the Indemnifying Party concerning the Indemnified Claim. If the
Indemnifying Party objects to all or any portion of the Indemnified Claim (an
"Objection"), the Indemnifying Party shall deliver its Objection in writing to
the Indemnified Party. Each such Objection shall state (A) if applicable, why
the Indemnified Claim is not recoverable from the Indemnifying Party; (B) the
amount of Losses objected to by the Indemnifying Party (the "Contested Amount");
and (C) if applicable, the amount of the Losses not objected to by the
Indemnifying Party (the "Uncontested Amount"). Any Objection by the Indemnifying
Party to an Indemnified Claim that is not received by the Indemnified Party
within 30 days of the Indemnifying Party's receipt of such Indemnified Claim
shall be deemed waived.

            (c) Uncontested Claims. If the Indemnifying Party does not object to
an Indemnified Claim from an Indemnified Party or fails to tender an Objection
within 30 days following its receipt of a Indemnified Claim from an Indemnified
Party, the Indemnifying Party shall promptly (but in any event within five days
after expiration of such 30-day period) tender payment to the Indemnified Party
in the amount of the Indemnified Claim in accordance with Section 9.8. Upon the
Indemnified Party's receipt of an Objection, the Uncontested Amount, if any,
shall promptly (but in any event within five days after such receipt) be
tendered by the Indemnifying Party in accordance with Section 9.8.

            (d) Resolution. The resolution of any Indemnification Dispute
concerning an Objection shall be made according to the procedures set forth in
Section 9.4. The Indemnified Party and the Indemnifying Party shall abide by any
resolution reached pursuant thereto. Upon receipt of any arbitration decision or
other resolution reached pursuant thereto, or any other final judgment entitling
an Indemnified Party to indemnification, the Indemnifying Party shall promptly
(but in any event within five days after receipt of such decision, resolution or
judgment) tender payment to the Indemnified Party in the amount of such
arbitration award, resolved amount or final judgment, as the case may be in
accordance with Section 9.8.

<PAGE>

            (e) No Waiver. Subject to the limitations otherwise set forth in
this Article IX, the failure of any Indemnified Party to exercise promptness in
notification of an Indemnified Claim, seeking payment of such a claim or seeking
other treatment of such a claim, shall not amount to a waiver or limitation of
such Indemnified Claim unless and to the extent the resulting delay materially
prejudices the position of the Indemnifying Party with respect to such claim.

      9.4 DISPUTE RESOLUTION - INDEMNIFICATION.

            (a) The parties agree that the following dispute resolution
procedures shall govern any dispute arising out of or in connection with any
claims for indemnification pursuant to this Article IX (an "Indemnification
Dispute").

            (b) In the event of an Indemnification Dispute, either party may
initiate negotiation proceedings by sending a letter (the "Negotiation Letter")
to the other party in which event the parties shall attempt in good faith to
resolve any Indemnification Dispute promptly by negotiation. Such Negotiation
Letter shall set forth the particulars of the dispute, the terms of the
Agreement that are involved and a suggested resolution. The recipient of the
letter must respond within 20 days and include a response to the proposed
solution. If the matter has not been resolved within 60 days of a party's
request for negotiation (the "Negotiation Period"), either party may initiate
arbitration as provided below.

            (c) In the event of an Indemnification Dispute that is not resolved
within the Negotiation Period, either party may seek expedited and binding
arbitration administered by the American Arbitration Association ("A.A.A.")
according to its Commercial Arbitration Rules subject to the following
procedures:

                  (i) The party desiring to initiate arbitration in connection
with any Indemnification Dispute shall notify the other party in writing, which
notice shall include a demand for arbitration and include a statement of the
matter in controversy in reasonable detail setting forth the basis of the
Indemnification Dispute and the relief being sought, and shall file a copy of
the demand for arbitration with the Administrator of the A.A.A. in Dallas, Texas
together with the appropriate filing fee.

                  (ii) The party receiving such notice must file any response or
counterclaim within 30 days after service of the demand. Failure to file a
counterclaim or response shall not operate to delay the arbitration proceedings.

                  (iii) The initiating party must file a response to any
counterclaim within 15 days of the filing of the counterclaim.

                  (iv) After the filing of the claim, response and counterclaim,
and any response to counterclaims, no further claims or counterclaims may be
made, except on motion to the arbitrators.

                  (v) The case shall be submitted to a panel of three
independent and impartial arbitrators jointly selected by the parties. If, after
a period of 15 days from the filing of

                           HOLLY ENERGY PARTNERS, L.P.

<PAGE>

the demand for arbitration, the parties are unable to jointly agree on the
identity of the three arbitrators, each party shall then appoint one arbitrator
within 15 days of the expiration of such 15 day period. If either party fails to
appoint an arbitrator, the A.A.A. shall, at the request of one of the parties,
appoint the second arbitrator. The two arbitrators so selected shall within 15
days after their designation select a neutral third arbitrator, who will serve
as the chair of the panel ("Chair"). If the two arbitrators are unable to select
a third arbitrator, the A.A.A. shall, at the request of one of the parties,
appoint the third arbitrator, who will serve as the Chair. Each arbitrator must
agree in writing prior to his or her acceptance as an arbitrator to abide by the
terms and conditions of this Agreement.

                  (vi) Once appointed, the arbitrators shall schedule a
pre-hearing status conference to be held in Dallas, Texas not more than 14 days
from the date of their appointment, and shall appoint a time for a final hearing
to be held in Dallas, Texas not more than 30 days from the date of the status
conference. The final hearing shall conclude no later than 30 days after its
commencement. The arbitrators shall render a written decision within 10 days
from the conclusion of the final hearing setting forth the arbitrators'
determination (and stating with reasonable detail the reasons for the
determination reached). Each party shall bear its own cost of preparing for and
presenting its case, including attorney's fees. The cost of arbitration,
including the fees and expenses of the arbitrators, will be shared equally by
each party, unless the arbitrators determine otherwise.

                  (vii) The Chair shall conduct discovery and resolve all
discovery disputes. The Chair shall authorize such discovery as may be shown to
be necessary to ensure a fair hearing; provided, however, that such discovery
shall be completed within 20 days from the date of the status conference. Except
as needed for presentation in lieu of a live appearance, each party shall be
limited to three business days (9:00 a.m. to 5:00 p.m.) of depositions. This
limitation shall apply to each separate arbitration that may be conducted
pursuant to this Agreement. The parties shall be entitled to engage in document
discovery by requesting production of documents. The parties shall use their
commercially reasonable efforts to serve responses or objections to such
requests within 10 days after receipt of such a request. The Chair shall resolve
any discovery disputes by such prehearing conference(s) as such arbitrator may
deem necessary. The parties agree that the Chair and any counsel of record to
the proceeding shall have the power of subpoena process and the power to compel
the parties to appear and produce documents for the purpose of the proceeding.

                  (viii) The arbitrators shall not be bound by the rules of
evidence or of civil procedure, but rather may consider such writings and oral
presentations as such arbitrators or the parties may deem desirable or
necessary. Prior to testifying, whether directly in the presence of the
arbitrators or through depositions, each witness shall be sworn to tell the
truth, subject to the perjury laws of the State of Texas.

                  (ix) A majority of the arbitrators may award injunctive relief
or any other legal or equitable remedy available from a court, including the
joinder of parties or consolidation of this arbitration with any other involving
common issues of law or fact which may promote judicial economy.

                  (x) This dispute resolution procedure is intended to be the
exclusive method of resolving any Indemnification Dispute.

                  (xi) Either party may apply to the United States District
Court for the Northern District of Texas to enforce any portion of this
arbitration agreement (as provided in USC Section 3) or to enter judgment upon
the award (as provided in 8 U.S.C. Section 9). Each party agrees that the
arbitration provisions set forth in this Section 9.4 and the decision and the
award of the arbitrators shall be treated as an absolute and final bar to any
suit instituted in any federal, state or local court relating to the
Indemnification Dispute, except as provided in the Federal Arbitration Act.

                  (xii) It is agreed that from the time of the filing of the
demand for arbitration to no more than 10 days after the status conference, the
parties shall meet and endeavor to formulate a written agreement governing as
many of the other aspects of the arbitration proceeding as can be resolved or
agreed upon, subject to the procedures and principles set forth herein, subject
to the Federal Arbitration Act, and subject to the Commercial Arbitration Rules.
In particular, the parties shall endeavor to reach agreement as to the specific
legal principles that the arbitrators shall apply to resolve the Indemnification
Dispute, stipulate to as many facts as possible, and frame as narrowly as
possible the issues which are submitted to the arbitrators for resolution.

                  (xiii) All aspects of an arbitration conducted pursuant to
this Section 9.4 shall be and remain confidential and all participants shall be
bound by judicially enforceable obligations of strict confidentiality except to
the extent the parties agree in writing to waive in whole or part such
confidentiality, or as otherwise required by applicable Law.

                  (xiv) If any provision of this Section 9.4 is adjudged to be
void or otherwise unenforceable, in whole or in part, such adjudication shall
not effect the validity of the remainder of this Agreement.

                  (xv) The arbitration shall follow the substantive law of the
State of Texas. This shall include the provisions of statutory law dealing with
arbitration, as it may exist at the time of the demand for arbitration, insofar
as said provisions are not in conflict with this Agreement.

      9.5 LIMITS OF LIABILITY.

            (a) Minimum Loss; Cap. No Indemnified Party shall be entitled to be
indemnified for Losses pursuant to Section 9.1(a)(iii) or Section 9.1(b)(iii)
unless and until the respective aggregate amount of all such Losses exceeds
$750,000 (the "Minimum Loss"). After the Minimum Loss is exceeded, the
Indemnified Party shall be entitled to be paid the entire amount of any Losses
pursuant to Section 9.1(a)(iii) or Section 9.1(b)(iii), which exceed the Minimum
Loss, subject to the other provisions of this Agreement; provided, however, that
(i) the aggregate liability of Transferee for Losses under Section 9.1(b)(iii)
shall not exceed $20,000,000 and (ii) the aggregate liability of the Alon
Parties for Losses under Section

                           HOLLY ENERGY PARTNERS, L.P.

<PAGE>

9.1(a)(iii), together with Environmental Costs and Liabilities under the
Environmental Agreement, shall not exceed $20,000,000.

            (b) Minimum Claim. If any claim or groups of related claims for
indemnification by an Indemnified Party that is indemnifiable under Section
9.1(a)(iii) or Section 9.1(b)(iii) of this Agreement results in respective
aggregate Losses to such Indemnified Party that do not exceed $10,000, such
Losses shall not be deemed to be Losses under this Agreement and shall not be
eligible for indemnification under this Article IX.

            (c) No Special Damages. In no event shall any Indemnifying Party be
liable to any Indemnified Party with respect to any matter arising under or in
relation to this Agreement for any special, consequential, punitive or exemplary
damages, except to the extent such damages are included within a judgment
rendered against an Indemnified Party with respect to a Third Party Claim for
which indemnification is available under the terms of this Article IX; provided,
however, that this Section 9.5(c) shall not apply to limit the damages a party
may seek under this Article IX with respect to any breach by any other party
under the Pipelines and Terminals Agreement to the extent such damages are
allowable under the Pipelines and Terminals Agreement.

      9.6 SURVIVAL OF COVENANTS, REPRESENTATIONS AND WARRANTIES. Covenants
contained in this Agreement, the Alon Ancillary Documents or the Transferee

and shall cause their respective Representatives and affiliates thereof to,
treat all Confidential Information as confidential, preserve the confidentiality

cause each of its affiliates thereof to use, all reasonable efforts to cause

of any securities exchange to disclose any Confidential Information, such party

the case of a disclosure pursuant to the Exchange Act, the rules of the SEC or
the rules of any securities exchange, such time period (which may be shorter

possible), so that the other party hereto may seek a protective order or other

further actions, including obtaining consents to assignment from third parties,

repayment is made in connection with a refinancing of the Rule 144A Debt for
indebtedness in an amount not less than the then outstanding principal amount of

economic risk of loss (as described in Treasury Regulation Section 1.704-2(i))
in a manner similar to that provided for in the Indemnification Agreement
entered into between Newco 2 and HEP Logistics Holdings, L.P. dated the Closing

acceleration thereof in accordance with the terms of the Indenture, (iii) in an
amount equal to the aggregate income or gain under Section 704(c) of the Code
that has been allocated to Newco 2 in accordance with the "remedial method" as
described in Treasury Regulation Section 1.704-3(d) pursuant to Section 1.8 of
this Agreement and Section 6.2(b)(iii) of the Transferee Partnership Agreement,

under Section 704(c) of the Code with respect to the Contributed Assets, or (v)
if such full or partial repayment is made in connection with a "Change of
Control" permitted above and such full or partial repayment is funded by
indebtedness in an amount not less than the amount of such repayment and for
which Newco 2 is provided the opportunity to bear the economic risk of loss (as
described in Treasury Regulation Section 1.704-2(i)) in a manner similar to that
provided for in the above-referenced Indemnification Agreement.

      12.3 ENTIRE AGREEMENT; AMENDMENT; WAIVER. This Agreement and the Exhibits
(including the Environmental Agreement), Annexes and Schedules attached hereto,
constitute the entire understanding between the parties with respect to the
subject matter hereof, and supersede all other understandings and negotiations
with respect thereto. This Agreement may be amended only in a writing signed by
all parties hereto. Any provision of this Agreement may be waived

only in a writing signed by the party to be charged with such waiver. No course
of dealing between the parties shall be effective to amend or waive any
provision of this Agreement.

      12.4 SEVERABILITY. If any term or other provision of this Agreement is
invalid, illegal, or incapable of being enforced under applicable Law, or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the economic or legal substance of
the transactions contemplated herein are not affected in any manner adverse to
any party. Upon such determination that any term or other provision of this
Agreement is invalid, illegal, or incapable of being enforced, the parties
hereto shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in a mutually
acceptable manner in order that the transactions contemplated herein are
consummated as originally contemplated to the fullest extent possible.

      12.5 PARTIES IN INTEREST. This Agreement shall be binding upon and inure
solely to the benefit of each party hereto and their successors and permitted
assigns, and nothing in this Agreement, express or implied, is intended to
confer upon any other person (other than the Indemnified Parties as provided in
Article IX and subject to Section 9.9) any rights or remedies of any nature
whatsoever under or by reason of this Agreement.

      12.6 GOVERNING LAW. This Agreement shall be governed by the internal laws
of the State of Texas, without reference to its conflict of law provisions.

      12.7 ASSIGNMENT TO LENDERS; ASSIGNMENT OF AGREEMENT TO SUBSIDIARY.

            (a) At any time, either of Transferee or the Alon Parties may make a
collateral assignment of its rights under this Agreement to any of its bona fide
lenders or debt holders, or a trustee or a representative for any of them, and
the non-assigning party shall execute an acknowledgment of such collateral
assignment in such form as may from time to time be reasonably requested;
provided, however, that unless written notice is given to the non-assigning
party that any such collateral assignment has been foreclosed upon, such
non-assigning party shall be entitled to deal exclusively with Transferee or the
Alon Parties, as the case may be, as to any matters arising under this Agreement
or any of the other agreements delivered pursuant hereto (other than for
delivery of notices required by any such collateral assignment).

            (b) Notwithstanding any contrary provisions contained in this
Agreement, Transferee and the Alon Parties agree that each of Transferee and the
Alon Parties (each an "Assignor"), each in its sole discretion, may assign any
or all of its rights and obligations arising under this Agreement to one or more
of its respective Subsidiaries (such Subsidiary, an "Assignee"), provided that
no such assignment shall relieve Assignor of any obligation or liability to
Transferee or the Alon Parties, as the case may be, under this Agreement, and
provided further that the following shall apply:

                  (i) Assignor will provide Transferee or the Alon Parties, as
the case may be, with prompt written notice of any such assignment.

<PAGE>

                  (ii) No such assignment shall be effected if the making of the
assignment will result in Transferee's or the Alon Parties' inability to obtain
any Consent.

                  (iii) Assignee shall irrevocably appoint Assignor as an
authorized representative and agent authorized to act for, to bind and to
receive notices and payments on behalf of Assignee in all matters arising from
or related to this Agreement, any of the other Ancillary Documents and the
transactions contemplated hereby and thereby.

                  (iv) Irrespective of any such assignment:

                        (A) Assignor shall remain jointly and severally liable
            with respect to any Retained Liabilities, with respect to an
            assignment by Transferors, and the Assumed Liabilities, with respect
            to an assignment by Transferee, and shall remain jointly and
            severally liable with respect to any other covenant, obligation or
            liability of Assignor under this Agreement, including, without
            limitation, the payment of all sums due from such Assignor under
            this Agreement, it being understood that all such covenants,
            obligations and liabilities shall constitute the direct and primary
            obligation of Assignor; and

                        (B) Without limiting the generality of the foregoing, if
            and to the extent that applicable Law would construe the retention
            by Assignor of the direct and primary obligation to perform any and
            all obligations, liabilities or covenants assigned to or assumed by
            Assignee to be a guaranty by Assignor of Assignee's performance,
            then Assignor hereby irrevocably, absolutely and unconditionally
            guarantees the full, prompt and faithful performance by such
            Assignee of all covenants and obligations to be performed by such
            Assignee under this Agreement.

                  (v) Transferee and the Alon Parties further hereby agree that
a separate action or actions may be brought and prosecuted against any Assignor
for any such covenant, obligation or liability assigned, whether action is
brought against Assignee or whether Assignee is joined in any such action or
actions, and Transferee and the Alon Parties hereby waive any right to require
Transferee or the Alon Parties, as the case may be, to proceed against any such
Assignee.

            (c) Except as otherwise provided in Sections 12.7(a) or 12.7(b)
above, this Agreement is not assignable by either Transferee or the Alon
Parties; provided that this Section 12.7(c) shall not apply to any merger, sale
of equity interests, or change of control involving a party hereto.

      12.8 NO WAIVER RELATING TO CLAIMS FOR FRAUD. The liability of any party
under Article IX shall be in addition to, and not exclusive of, any other
liability that such party may have at law or equity based on such party's
fraudulent acts or omissions. None of the provisions set forth in this
Agreement, including but not limited to the provisions set forth in Article IX,
shall be deemed a waiver by any party to this Agreement of any right or remedy
which such party may have at law or equity based on any other party's fraudulent
acts or omissions, nor shall

any such provisions limit, or be deemed to limit (a) the amounts of recovery
sought or awarded in any such claim for fraud, (b) the time period during which
a claim for fraud may be brought, or (c) the recourse which any such party may
seek against another party with respect to a claim for fraud; provided, however,
that with respect to such rights and remedies at law or equity, the parties
further acknowledge and agree that none of the provisions of this Section 12.8,
nor any reference to this Section 12.8 throughout this Agreement, shall be
deemed a waiver of any defenses which may be available in respect of actions or
claims for fraud, including but not limited to, defenses of statutes of
limitations or limitations of damages.

      12.9 DISPUTE RESOLUTION - GENERAL.

            (a) Except for an Indemnification Dispute which shall be governed by
Section 9.4 hereof, if any dispute or controversy, including a failure of the
parties to agree on an independent accountant or appraisal pursuant to Section
1.8 hereof, arises out of this Agreement or any of the Ancillary Documents or
the performance, breach, validity, interpretation or enforcement thereof (such
dispute or controversy, a "General Dispute"), it is in the best interests of the
parties for such General Dispute to be resolved in the shortest time and with
the lowest cost of resolution practicable. Consequently, the parties shall
resolve any General Dispute without resort to the courts. If any General Dispute
arises, the parties will comply with the following procedures:

                  (i) The party believing a General Dispute to exist will give
the other party prompt written notice thereof, setting forth in reasonable
detail the facts alleged to give rise to such General Dispute, any relevant
contractual provisions, the nature of any claimed default or breach and a
statement of the manner in which such party believes the General Dispute should
be resolved.

                  (ii) Within 20 days after receipt of such notice, the party
against whom relief is sought in connection with such General Dispute will
deliver a written response, setting forth in reasonable detail its views of the
facts alleged to give rise to such General Dispute, any relevant contractual
provisions, the nature of the claimed default or breach and a statement of the
manner in which such party believes the General Dispute should be resolved.

                  (iii) If the parties do not agree on the manner in which the
General Dispute should be resolved, they will arrange to hold a meeting within
10 days after delivery of the response. Each party will have in attendance at
such meeting a representative with the authority to resolve such General
Dispute. At the meeting (and any adjournments thereof), the parties will
negotiate in an attempt to agree as to whether a General Dispute exists, the
exact nature of the General Dispute and the manner in which the General Dispute
should be resolved. If deemed appropriate by the parties, a professional
mediator may be engaged to assist in resolving the General Dispute. Any
resolution of the General Dispute will be evidenced by a written agreement
setting forth in reasonable detail the actions to be taken by each party. If no
such written agreement is reached within 20 days after the first meeting (the
"General Dispute Negotiation Period"), the parties may pursue binding
arbitration with respect to such General Dispute pursuant to Section 12.9(b).

                          HOLLY ENERGY PARTNERS, L.P.
                             CONTRIBUTION AGREEMENT

            (b) Mandatory Binding Arbitration.

                  (i) If any General Dispute is unresolved by the end of the
General Dispute Negotiation Period, a binding arbitration will be held in
Dallas, Texas, upon notice by either party (the "General Arbitration Notice").
Subject to the provisions of this Section 12.9(b), the parties will agree upon
the rules of the arbitration prior to the arbitration based upon the nature of
the disagreement. To the extent that the parties cannot agree on the rules of
the arbitration, the Commercial Arbitration Rules of the AAA will apply, and the
arbitration will be conducted on a confidential basis strictly in accordance
with the terms of this Agreement and the governing law of the State of Texas as
specified under Section 12.6.

                  (ii) The arbitration shall be conducted before a panel of
three independent and impartial arbitrators. Each party will be entitled to
select one arbitrator within 20 days of the date of the General Dispute
Arbitration Notice. If a party fails to select an arbitrator within such 20 day
period, the Dallas, Texas office of the AAA shall appoint an arbitrator for such
party. The two individuals so selected will then select the third arbitrator
within 20 days. If the two individuals selected fail to select a third
arbitrator within such 20 day period, the Dallas office of the AAA shall appoint
a third arbitrator. The panel of arbitrators will be selected no later than 45
days after the date of the General Dispute Arbitration Notice. Each member of
the arbitration panel, if possible, must be experienced in legal and operational
matters related to refined petroleum product pipelines.

                  (iii) The arbitrators' decision will be considered as a final
and binding resolution of the General Dispute and will not be subject to appeal.
THE PARTIES HEREBY ACKNOWLEDGE AND AGREE THAT THE UNITED STATES DISTRICT COURT
FOR THE NORTHERN DISTRICT OF TEXAS SHALL HAVE EXCLUSIVE JURISDICTION OVER THE
PARTIES. FURTHER, THE PARTIES HEREBY ACKNOWLEDGE AND AGREE THAT ANY DECISION BY
AN ARBITRATOR SHALL BE ONLY ENTERED AS AN ORDER IN THE UNITED STATES DISTRICT
COURT FOR THE NORTHERN DISTRICT OF TEXAS. No party will sue the other except for
enforcement of the arbitrator's decision if the other party is not performing in
accordance with the arbitrator's decision.

                  (iv) The parties shall bear equally the fees and expenses of
the arbitration, unless the arbitrators decide otherwise. Each party will bear
the costs of its own counsel, witnesses (if any) and employees, unless the
arbitrators decide otherwise.

      12.10 CAPTIONS. The captions in this Agreement are for purposes of
reference only and shall not limit or otherwise affect the interpretation
hereof.

      12.11 COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

      12.12 DIRECTOR AND OFFICER LIABILITY. Except to the extent that they are a
party hereto, the directors, managers, officers, partners and stockholders of
Transferee, the Alon Parties and

                          HOLLY ENERGY PARTNERS, L.P.

<PAGE>

their respective affiliates shall not have any personal liability or obligation
arising under this Agreement (including any claims that another party may
assert) other than as an assignee of this agreement or pursuant to a written
guarantee.

      12.13 SPECIFIC PERFORMANCE. The parties recognize that in the event
Transferors should refuse to perform under the provisions of this Agreement,
monetary damages alone will not be adequate. Transferee shall therefore be
entitled, in addition to any other remedies which may be available, including
money damages, to obtain specific performance of the terms of this Agreement. In
the event of any action to enforce this Agreement specifically, Transferors
hereby waive the defense that there is an adequate remedy at law.
