Ltd., a member of MUFG, a global financial group (“MUFG”), Wells Fargo Bank,

SunTrust Bank (“SunTrust Bank”), SunTrust Robinson Humphrey, Inc. (“STRH”), UBS

together with GS Bank, JPMorgan, Mizuho, MUFG, Wells Fargo Bank, Wells Fargo
Securities, Wells Fargo Holdings, SunTrust Bank, STRH and UBS AG, collectively
the “Commitment Parties”, “we” or “us”) that Tesoro Corporation, a Delaware
corporation (the “Borrower” or “you”), will acquire (the “Acquisition”) Western
Refining, Inc., a Delaware corporation (the “Target”). You have further advised
us that, in connection with the foregoing, you intend to consummate the other
Transactions described in the Transaction Description attached hereto as
Exhibit A (the “Transaction Description”). Capitalized terms used but not
defined herein shall have the meanings assigned to them in the Transaction
Description and in the Term Sheets described below. This commitment letter,
together with all Exhibits hereto, is referred to as this

--------------------------------------------------------------------------------

“Commitment Letter”. As of the date hereof, the Commitment Letter dated November
16, 2016, among GS Bank, Goldman Sachs Lending Partners LLC (“GSLP”) and the
Borrower (together with all Exhibits thereto, the “Original Commitment Letter”)
shall be deemed amended and restated in its entirety as set forth in this
Commitment Letter, and the agreements, terms and conditions set forth in this
Commitment Letter shall control in their entirety the agreements, terms and
conditions set forth in the Original Commitment Letter. For the avoidance of
doubt, as of the date hereof, GSLP shall not have any commitment under either
this Commitment Letter or the Original Commitment Letter.
1.Commitment. Based upon the foregoing, on the terms set forth in this
Commitment Letter and subject only to the conditions expressly set forth in
Exhibit E of this Commitment Letter, (a) GS Bank hereby commits to provide to
the Borrower 30%, JPMorgan hereby commits to provide to the Borrower 15%, Mizuho
hereby commits to provide to the Borrower 15%, MUFG hereby commits to provide to
the Borrower 15%, Wells Fargo Holdings hereby commits to provide to the Borrower

principal amount of the Bridge Facility upon the principal terms set forth in
the 364-day Senior Unsecured Bridge Facility Summary of Principal Terms and
Conditions attached hereto as Exhibit B and incorporated by reference herein
(the “Bridge Facility Term Sheet”) and (b) if the requisite consent of the

hereby commits to provide to the Borrower 30%, JPMorgan hereby commits to
provide to the Borrower 15%, Mizuho hereby commits to provide to the Borrower
15%, MUFG hereby commits to provide to the Borrower 15%, Wells Fargo Bank hereby
commits to provide to the Borrower 15%, SunTrust Bank hereby commits to provide

each case, of the Backstop Facility to replace the Existing Credit Facility upon
the principal terms set forth in the Senior Secured Backstop Facility Summary of
Principal Terms and Conditions attached hereto as Exhibit D and incorporated by
reference herein (the “Backstop Facility Term Sheet” and, together with the
Transaction Description, the Summary of Existing Credit Facility Amendments
attached hereto as Exhibit C, the Conditions Precedent to the Closing attached
hereto as Exhibit E and the Bridge Facility Term Sheet, the “Term Sheets”). It
is understood and agreed that any event occurring after the date hereof and
prior to the initial funding of the Bridge Facility on the Closing Date that
would result in a mandatory prepayment or commitment reduction with respect to
the Bridge Facility as set forth in the Bridge Facility Term Sheet under
“Mandatory Prepayments/Commitment Reductions” shall reduce the amount of the
Bridge Facility, and the aggregate amount of the Commitment Parties’ commitments
hereunder in respect of the Bridge Facility (on a pro rata basis as between the
Commitment Parties, based on the amount of their respective commitments under
the Bridge Facility), on a dollar-for-dollar basis, and you agree to give the
Commitment Parties prompt written notice of the occurrence of any such event,
together with a reasonably detailed calculation of the amount of any such
reduction. It is understood and agreed that the commitments and other
obligations of the Commitment Parties hereunder are several and not joint. As
used in this Commitment Letter, the term “Facilities” means the Bridge Facility,
the Backstop Facility and the Incremental Revolving Facility, and the term
“Committed Facilities” means the Bridge Facility and the Backstop Facility.

--------------------------------------------------------------------------------

2.    Appointment of Roles. You hereby appoint (a) GS Bank, JPMorgan, Mizuho,
MUFG and Wells Fargo Securities to act, and each of GS Bank, JPMorgan, Mizuho,
MUFG and Wells Fargo Securities hereby agrees to act, (i) as joint lead
arrangers and joint bookrunners for the Bridge Facility (in such capacities, the
“Bridge Lead Arrangers”) and (ii) as joint lead arrangers and joint bookrunners
for the Backstop Facility (in such capacities, the “Backstop Lead Arrangers”),
(b) GS Bank to act, and GS Bank hereby agrees to act, as the sole administrative
agent for the Bridge Facility and as the sole administrative agent for the
Backstop Facility, and (c) STRH and UBS Securities to act, and each of STRH and
UBS Securities hereby agrees to act, as co-managers for each of the Bridge
Facility and the Backstop Facility, in each case on the terms set forth in this
Commitment Letter and subject only to the conditions expressly set forth in
Exhibit E to this Commitment Letter.
You also hereby appoint JPMorgan and GS Bank to act, and each of JPMorgan and GS
Bank hereby agrees to act, as joint lead arrangers and joint bookrunners (in
such capacities, the “Amendment Lead Arrangers” and, together with the Bridge
Lead Arrangers and the Backstop Lead Arrangers, the “Lead Arrangers”) for the
arrangement of the Existing Credit Facility Amendment and the Incremental
Revolving Facility. In its capacity as Amendment Lead Arranger, each Amendment
Lead Arranger agrees to use its commercially reasonable efforts to obtain the
requisite consent of lenders under the Existing Credit Facility (the “Existing
Lenders”) to the Existing Credit Facility Amendment and to arrange a syndicate
of Lenders (as defined below) to provide the Incremental Revolving Facility, it
being understood and agreed that (a) the Amendment Lead Arrangers shall endeavor
to obtain the requisite consent to the Existing Credit Facility Amendment within
90 days after the date hereof, (b) the Additional Amendment may be obtained in
the same amendment agreement as the Specified Amendment or in one or more
subsequent amendment agreements, all as determined by the Amendment Lead
Arrangers, and obtaining the requisite consent for the Additional Amendment or
arranging the Incremental Revolving Facility shall not be a condition to or
cause for delay in entering into the Specified Amendment, and (c) if the
requisite consent for the Specified Amendment shall not have been obtained on or
prior to the date that is 90 days after the date hereof, the Amendment Lead
Arrangers may at their discretion cease seeking to obtain the requisite consents
for the Existing Credit Facility Amendment and to arrange the Incremental
Revolving Facility. You acknowledge that this Commitment Letter is neither an
expressed nor an implied commitment by any Amendment Lead Arranger or any
affiliate of any Amendment Lead Arranger to consummate the Existing Credit
Facility Amendment (or any part thereof) or to provide any portion of the
Incremental Revolving Facility or to hold or purchase any existing loans or
commitments under the Existing Credit Facility in order to facilitate the
consummation of the Existing Credit Facility Amendment (or any part thereof),
nor is it a guarantee with respect to the outcome of the Existing Credit
Facility Amendment or the arrangement of the Incremental Revolving Facility. The
obligations of the Amendment Lead Arrangers to endeavor to arrange the requisite
consent to the Existing Credit Facility Amendment, or to arrange the Incremental
Revolving Facility, shall not require any Amendment Lead Arranger or any
affiliate of any Amendment Lead Arranger to share any of the fees payable to it
in connection with the Transactions (or otherwise expend any amounts) in order
to achieve such consents or successful arrangement.

    
3

--------------------------------------------------------------------------------

It is agreed that no other agents, co-agents, arrangers, co-arrangers,
bookrunners, managers or co-managers will be appointed, no other titles will be
awarded and no compensation (other than compensation expressly contemplated by
this Commitment Letter or the Fee Letters (as defined below)) will be paid by
you or your subsidiaries to any Lender as consideration for its participation in
the Facilities or to any Existing Lender as consideration to its consent to the
Existing Credit Facility Amendment, in any case relating to the Existing Credit
Facility Amendment or the Incremental Revolving Facility, unless you, JPMorgan
and GS Bank shall so agree, and in any other case, unless you and we shall so
agree. It is further agreed that (a) GS Bank will appear on the top left of the
cover page of any marketing materials for each of the Bridge Facility and the
Backstop Facility, and will hold the roles and responsibilities conventionally
understood to be associated with such name placement, and (b) JPMorgan will
appear on the top left of the cover page of any marketing materials for the
Incremental Revolving Facility and the Existing Credit Facility Amendment, and
will hold the roles and responsibilities conventionally understood to be
associated with such name placement.
3.    Syndication. The Commitment Parties will syndicate the Incremental
Revolving Facility and reserve the right, prior to or after the execution of the
definitive documentation therefor, to syndicate the Committed Facilities to one
or more financial institutions or other lenders in consultation with and
reasonably acceptable to you (together with the Commitment Parties, the
“Lenders”), it being understood that Permitted Lenders (as defined below) are
reasonably acceptable to you, and you understand that the Facilities may be
separately syndicated. The Commitment Parties agree not to syndicate the
Facilities to, or assign their commitments under the Committed Facilities to,
(a) certain banks, financial institutions and other institutional lenders that
have been specified by you in writing to GS Bank on November 16, 2016, (b) any
of your competitors that have been specified to the Lead Arrangers by you in
writing before the Closing Date or to the applicable Administrative Agent by you
in writing after the Closing Date at any time and from time to time and (c) in
the case of each of clauses (a) and (b), any of their respective affiliates
(other than any bona fide debt funds) that are either (x) identified in writing
to the Lead Arrangers or, after the Closing Date, the applicable Administrative
Agent by you from time to time or (y) clearly identifiable as affiliates of such
persons on the basis of the similarity of such affiliate’s name (the foregoing
persons, collectively, the “Disqualified Lenders”), it being understood and
agreed that the foregoing provisions shall not apply retroactively to disqualify
any person that shall have become a Disqualified Lender after the date of the
launch of the general syndication for any Facility if such person shall have
become a Lender or participant (or shall have been allocated a commitment as
part of the general syndication of such Facility) prior thereto, but shall
disqualify such person from taking any further assignment or participation
thereafter). Notwithstanding our right to syndicate the Facilities and to
receive commitments with respect thereto, other than (i) in connection with any
assignment between a Commitment Party and any of its affiliates (including, for
the avoidance of doubt, between GS Bank and GSLP), (ii) any assignment to any
person that (A) is an Existing Lender as of November 16, 2016 or (B) is a
commercial or investment bank or an insurance company that, in each case under
this clause (B), at the time of such assignment has a long-term senior
unsecured, non-credit enhanced debt rating of at least BBB by Standard & Poor’s
Ratings Service (“S&P”) or Baa2 by Moody’s Investors Service, Inc. (“Moody’s”)
and is not a Disqualified Lender or (iii) any assignment to any other person to
which you shall have consented in writing (each assignee described in clauses
(i), (ii) and (iii) above being

    
4

--------------------------------------------------------------------------------

referred to as a “Permitted Lender”), (A) no Commitment Party shall be relieved,
released or novated from its obligations hereunder (including its obligation to
fund the Committed Facilities on the Closing Date) in connection with any
syndication, assignment or participation of the Committed Facilities until after
the Closing Date has occurred, (B) no assignment or novation shall become
effective (as between you and any of us) with respect to all or any portion of
any Commitment Party’s commitments in respect of any Committed Facility until
the initial funding of such Committed Facility by such Commitment Party and (C)
unless you otherwise agree in writing, each Commitment Party shall retain
exclusive control over all rights and obligations with respect to its
commitments in respect of the Committed Facilities and this Commitment Letter,
including all rights with respect to consents, modifications, supplements,
waivers and amendments, until after the Closing Date has occurred.
Until the earlier to occur of (a) the date on which a Successful Syndication (as
defined in the Arranger Fee Letter) shall have occurred and (b) 60 days after
the Closing Date (such period, the “Syndication Period”), you agree to assist us
in arranging the Existing Credit Facility Amendments and completing syndications
of the Facilities that are reasonably satisfactory to the Lead Arrangers and
you. Such assistance shall include (i) your using commercially reasonable
efforts to ensure that the arrangement and syndication efforts benefit from your
and your subsidiaries’ existing banking relationships and, to the extent
practical and appropriate, the existing banking relationships of the Target and
its subsidiaries, (ii) direct contact between your senior management, on the one
hand, and the Existing Lenders and the proposed Lenders, on the other hand (and
subject to your rights under the Acquisition Agreement, your using commercially
reasonable efforts to ensure such contact between the senior management of the
Target, on the one hand, and the Existing Lenders and the proposed Lenders, on
the other hand), at such times during normal business hours as are mutually
agreed, (iii) your assistance (and subject to your rights under the Acquisition
Agreement, your using commercially reasonable efforts to cause the Target and
its subsidiaries to assist) in prompt preparation of customary confidential
information memoranda (the “Confidential Information Memoranda”) and other
customary marketing materials to be used in connection with the arrangement and
syndication efforts by providing information and other customary materials
reasonably requested by any of us in connection therewith (such marketing
materials and the Confidential Information Memoranda, collectively, with the
Term Sheets and the information and projections referred to in the next
succeeding paragraph, the “Information Materials”), (iv) the hosting, with the
Lead Arrangers, of one or more meetings of and conference calls with the
Existing Lenders and the prospective Lenders, at times and locations mutually
agreed upon and upon reasonable advance notice (provided that, without your
consent, there shall be no more than one general bank meeting for the
Incremental Revolving Facility and one general bank meeting for the Committed
Facilities), (v) your ensuring that there are not any competing issues of debt
securities or commercial bank or other credit facilities (including incremental
commitments or loans or extensions of existing commitments or loans) of you or
your subsidiaries (and, subject to your rights under the Acquisition Agreement,
your using commercially reasonable efforts to ensure the same with respect to
the Target and its subsidiaries) offered, placed, announced or arranged
(excluding the Facilities, the Term Loan Facility, the Senior Notes or any other
debt securities issued for the purpose of consummating the Acquisition or any
debt securities issued by, or commercial bank or other credit facilities of,
Tesoro Logistics LP, a Delaware limited partnership (“Tesoro Logistics”), and
its subsidiaries), to the extent such offering, placement, announcement or
arrangement could

    
5

--------------------------------------------------------------------------------

reasonably be expected to materially impair the arrangement of the Specified
Amendment, the arrangement or the primary syndication of the Facilities or the
marketing of the Senior Notes or the Term Loan Facility, in each case, without
the prior written consent of the Lead Arrangers (such consent not to be
unreasonably withheld or delayed) (it being understood that the Borrower’s and
its subsidiaries’ deferred purchase price obligations, ordinary course working
capital facilities (other than any new or incremental revolving credit
facilities), borrowings under existing facilities (other than under any
incremental commitments established or extended under such facilities after
November 16, 2016) and ordinary course capital leases, purchase money and
equipment financings, and any indebtedness of the Target and its subsidiaries
permitted to be incurred and remain outstanding pursuant to the Acquisition
Agreement will not, in each case, be deemed to materially impair the arrangement
of the Specified Amendment, the primary syndication of the Facilities or the
marketing of the Senior Notes or the Term Loan Facility), and (vi) prior to the
launch of the arrangement and syndication of the Facilities and the commencement
of the marketing period for the Senior Notes, using your commercially reasonable
efforts to (x) obtain an updated monitored public corporate credit rating from
S&P and an updated monitored public corporate family rating from Moody’s, in
each case, with respect to the Borrower and (y) obtain public ratings of the
Senior Notes and, if applicable, the Term Loan Facility from each of S&P and
Moody’s. Such assistance shall also include, in respect of the Existing Credit
Facility Amendment, your cooperating with the Amendment Lead Arrangers in
seeking to obtain the requisite consent of the Existing Lenders to the Existing
Credit Facility Amendment (including, without limitation, by negotiating in good
faith the terms of the Existing Credit Facility Amendment (including as to such
amendments of the Existing Credit Facility as may be reasonably requested by the
Existing Lenders in respect of the Acquisition and the Target and its
subsidiaries and by consenting to such assignments under the Existing Credit
Facility as the Amendment Lead Arrangers may request be made to facilitate
obtaining such requisite consent) and your entering into the Specified Amendment
at such time as the Amendment Lead Arrangers shall advise you that the Existing
Lenders are willing to provide the requisite consent thereto. Without limiting
your obligations to assist with arrangement and syndication efforts as set forth
above, each Commitment Party agrees that neither the obtaining of the requisite
consent to the Existing Credit Facility Amendment nor the commencement or the
completion of the syndication of any Facility or the receipt of any rating
referred to above is a condition to its commitment hereunder.
The Lead Arrangers will manage, in consultation with you, all aspects of the
arrangement and syndication of the Facilities and the arrangement of the
Existing Credit Facility Amendment, including, without limitation, selection of
Lenders, determination of when the Lead Arrangers will approach the Existing
Lenders or potential Lenders and the time of acceptance of the Lenders’
commitments or the Existing Lenders’ consents and any naming rights, and will,
subject to your consent in the case of any Lender that is not a Permitted
Lender, determine the Lenders whose commitments will be accepted, the final
allocations of the commitments among the Lenders and the amount and distribution
of fees among the Existing Lenders and the Lenders. To assist the Lead Arrangers
in their syndication and arrangement efforts, you agree promptly to prepare and
provide to the Lead Arrangers (and, subject to your rights under the Acquisition
Agreement, to use commercially reasonable efforts to cause the Target to prepare
and provide to the Lead Arrangers) all customary information with respect to
you, the Target and your and its subsidiaries and the Transactions, including,
without limitation, all customary financial information and the projections

    
6

--------------------------------------------------------------------------------

of and other forward-looking information with respect to you, the Target and
your and its subsidiaries after the Transactions (the “Projections”), that the
Lead Arrangers may reasonably request in connection with the structuring,
arrangement and syndication of the Facilities and the arrangement of the
Existing Credit Facility Amendment.
You acknowledge that (a) subject to the confidentiality obligations contained
herein, the Commitment Parties on your behalf will make available the
Information Materials and other information relating to the Existing Credit
Facility Amendment and the Facilities, including drafts and final definitive
documentation with respect thereto, to the Existing Lenders and the proposed
Lenders by posting the Information Materials and such other information on
IntraLinks, SyndTrak, Datasite or another similar electronic system, in
accordance with the Lead Arrangers’ standard syndication practices (including
hard copy and via electronic transmissions), it being understood and agreed that
all information so disseminated or provided shall continue to be subject to the
terms of any written confidentiality agreements heretofore or hereafter executed
by the Lead Arrangers and the confidentiality provisions set forth herein, and
(b) certain Existing Lenders and prospective Lenders (such Lenders, “Public
Lenders”; all other Existing Lenders or Lenders, “Private Lenders”) may have
personnel that do not wish to receive Private Lender Information (as defined
below). If requested, you agree to assist in the preparation of a version of the
Confidential Information Memoranda (and related marketing materials) and
presentations to be distributed to Public Lenders in connection with the
arrangement of the Existing Credit Facility Amendment and the arrangement and
syndication of the Facilities consisting exclusively of information and
documentation that is either (i) publicly available or (ii) not material with
respect to you, your subsidiaries, the Target or its subsidiaries or any
securities of any of the foregoing for purposes of the United States Federal or
state securities laws (the information and documentation described in clauses
(i) and (ii) being “Public Lender Information”). Any information and
documentation that is not Public Lender Information is referred to herein as
“Private Lender Information”. You further agree that, unless expressly
designated as “PUBLIC”, each document to be disseminated by the Lead Arrangers
to any Existing Lender or any Lender in connection with the arrangement of the
Existing Credit Facility Amendment or the arrangement and syndication of the
Facilities will be deemed to contain Private Lender Information. It is
understood that in connection with your assistance described above, customary
authorization letters will be included in any Confidential Information
Memorandum that authorize the distribution of such Confidential Information
Memorandum to the Existing Lenders or prospective Lenders, containing a
representation from you to the Lead Arrangers that the public-side version does
not include any Private Lender Information and a customary “10b-5”
representation consistent with Section 6 below (and you shall, subject to your
rights under the Acquisition Agreement, use commercially reasonable efforts to
cause the Target to deliver customary authorization letters containing such
representations from the Target to the Lead Arrangers, it being understood that
the customary “10b-5” representation by the Target, in the case of authorization
letters delivered by the Target, shall not be qualified by knowledge), and
exculpating (x) the Commitment Parties and their respective affiliates with
respect to any liability related to the use of the contents of such Confidential
Information Memorandum or any related marketing material by the recipients
thereof and (y) you and your subsidiaries with respect to any liability related
to the misuse of the contents of such Confidential Information Memorandum. You
agree that the Commitment Parties on your behalf may distribute the following
documents to all Public Lenders and Private Lenders (other than Disqualified
Lenders), unless, after having been given a reasonable

    
7

--------------------------------------------------------------------------------

opportunity to review such documents, you advise the Commitment Parties that
such material should only be distributed to Private Lenders: (a) drafts and
final definitive documentation with respect to the Facilities and the Existing
Credit Facility Amendment; (b) administrative materials prepared by the Lead
Arrangers for the Existing Lenders or prospective Lenders (such as a lender
meeting invitation, bank allocation, if any, and funding and closing memoranda);
and (c) notification of changes in the terms of the Facilities or the Existing
Credit Facility Amendment. If you advise us in writing that any of the foregoing
items should be distributed only to Private Lenders, then the Commitment Parties
will not distribute such materials to Public Lenders without further discussions
with you. At our request, you shall designate information to be distributed
solely to Public Lenders by clearly and conspicuously designating the same as
“PUBLIC” (it is understood that you shall not otherwise be under any obligation
to designate information as “PUBLIC”).
4.    Fees. As consideration for our commitments hereunder and our undertakings
to arrange, manage, structure and syndicate the Facilities and arrange the
Existing Credit Facility Amendment, you agree to pay to us the fees and fulfill
the other obligations set forth in the Term Sheets and in the amended and
restated arranger fee letter dated the date hereof, among us and you (the
“Arranger Fee Letter”; the original arranger fee letter dated November 16, 2016,
among you, GS Bank and GSLP that is being so amended and restated is referred to
herein as the “Original Arranger Fee Letter”), the revolver administrative agent
fee letter dated the date hereof, between you and JPMorgan (the “Revolver
Administrative Agent Fee Letter”) and the administrative agent fee letter dated
November 16, 2016, among you, GS Bank and GSLP (the “Administrative Agent Fee
Letter” and, together with the Arranger Fee Letter and the Revolver
Administrative Agent Fee Letter, the “Fee Letters”).
5.    Conditions Precedent. Our respective commitments and agreements hereunder
are subject solely to the satisfaction or waiver of the conditions expressly
stated in Exhibit E hereto; it being understood that there are no conditions
(implied or otherwise) to our respective commitments hereunder (including
compliance with the terms of the Commitment Letter, the Fee Letters and the Loan
Documents) other than those that are expressly stated in Exhibit E (and upon
satisfaction or waiver of such conditions, the initial funding under the
Committed Facilities shall occur). Notwithstanding anything in this Commitment
Letter, the Fee Letters, the Loan Documents or any other letter agreement or
other undertaking to the contrary, (a) the only representations and warranties
the accuracy of which shall be a condition to availability of the Committed
Facilities on the Closing Date shall be (i) the Acquisition Agreement
Representations (as defined below) and (ii) the Specified Representations (as
defined below) and (b) the terms of the Loan Documents, to the extent not
expressly set forth in the Exhibits hereto, shall be in a form such that they do
not impair availability of the Committed Facilities on the Closing Date if the
conditions expressly set forth in Exhibit E hereto are satisfied. For purposes
of the foregoing, (A) “Acquisition Agreement Representations” means such
representations and warranties made by the Target in the Acquisition Agreement
as are material to the interests of the Lenders, but only to the extent that you
(or your applicable subsidiaries) have the right (taking into account any
applicable cure periods) to terminate your (or its) obligation to consummate the
Acquisition under the Acquisition Agreement or the right not to consummate the
Acquisition pursuant to the Acquisition Agreement as a result of a breach of
such representations and warranties, and (B) “Specified Representations” means
the representations and warranties of the Loan Parties set forth in the Loan
Documents relating to

    
8

--------------------------------------------------------------------------------

corporate or other organizational existence of the Loan Parties, organizational
power and authority (as to execution, delivery and performance of the Loan
Documents) of the Loan Parties, the due authorization, execution and delivery of
the Loan Documents by the Loan Parties, enforceability and governmental
authorizations, in each case as it relates to entering into and performance of
the Loan Documents against or by the Loan Parties, the Loan Documents not
conflicting with the Loan Parties’ respective organizational documents, the Loan
Documents and the Transactions not conflicting with the Existing Tesoro
Indentures (as defined below), solvency as of the Closing Date (after giving
effect to the Transactions) of the Borrower and its restricted subsidiaries on a
consolidated basis (such representation and warranty to be consistent with the
solvency certificate in the form set forth in Exhibit F hereto), Federal Reserve
margin regulations, Investment Company Act status, subject to permitted liens,
the creation, validity and perfection of the security interests granted in the
collateral (solely in the case of the Backstop Facility), compliance with
Patriot Act and use of proceeds not violating OFAC and FCPA. The provisions in
this Section 5 are referred to as the “Limited Conditionality Provisions.” For
the avoidance of doubt, “Loan Documents” as used in this Commitment Letter shall
mean (i) if the Specified Amendment is not obtained prior to the Closing Date,
the Bridge Documentation and the Backstop Documentation and (ii) if the
Specified Amendment is obtained prior to the Closing Date, the Bridge
Documentation only. For purposes of the foregoing, “Existing Tesoro Indentures”
means (x) Indenture dated as of March 18, 2014, between the Borrower and U.S.
Bank National Association, as trustee, and (y) Indenture, dated as of September
27, 2012, between the Borrower and U.S. Bank National Association, in each case,
together with the forms of notes issued thereunder and as supplemented from time
to time.
6.    Information. You hereby represent and warrant (but the accuracy of such
representation and warranty shall not be a condition to the commitments
hereunder or the funding of the Committed Facilities) that (a) all written
information (other than the Projections, estimates and information of a general
economic, forward looking or industry nature and, prior to the Closing Date,
limited to your knowledge in the case of any such information as to the Target
and its subsidiaries) (the “Information”) that has been or will be made
available to any of the Commitment Parties by you or any of your representatives
or affiliates on your behalf, when taken as a whole, is or will be, when
furnished, correct in all material respects and does not or will not, as the
case may be, taken as a whole, contain any untrue statement of a material fact
or omit to state any material fact necessary in order to make the statements
contained therein not materially misleading in light of the circumstances under
which such statements are made (when taken as a whole after giving effect to all
supplements and updates thereto) and (b) the Projections that have been made or
will be made available to any of the Commitment Parties by you or any of your
representatives or affiliates on your behalf and that have or will be made
available to any of the Commitment Parties or any Lender in connection with the
Transactions have been or will be, as the case may be, prepared in good faith
based upon assumptions believed by the preparer thereof to be reasonable at the
time so made available (it being recognized by us that such Projections are
subject to significant uncertainties and contingencies, many of which are beyond
your control, are not to be viewed as facts, that actual results during the
period or periods covered by any such Projections may differ from the projected
results and such differences may be material, and that no assurance can be given
that any projection will be realized). You agree to supplement the Information
and the Projections from time to time until the later of the Closing Date and
the completion of the Syndication Period so that, assuming such Information and
the Projections were so made available at any time prior to

    
9

--------------------------------------------------------------------------------

such later date, the representation and warranty in the preceding sentence
remains correct. In syndicating and arranging the Facilities and the Existing
Credit Facility Amendment, we will be entitled to use and rely primarily on the
Information and the Projections without responsibility for independent
verification thereof.
7.    Expenses. You agree to pay or reimburse each Commitment Party for all
reasonable and documented out-of-pocket fees and expenses (including, without
limitation, expenses of such Commitment Party’s due diligence investigation,
syndication expenses, travel expenses and reasonable fees, disbursements and
other charges of outside counsel identified in the Term Sheets and one local
counsel (limited to a single firm of counsel for all of the Commitment Parties)
retained in any material relevant jurisdiction to the extent reasonably
necessary) incurred by such Commitment Party or its affiliates (whether incurred
before or after the date hereof) in connection with the Facilities and the
Existing Credit Facility Amendment and the preparation, negotiation, execution
and delivery of this Commitment Letter, the Original Commitment Letter, the Fee
Letters, the Original Arranger Fee Letter, the Loan Documents and any security
arrangements in connection therewith and any such fees and expenses incurred in
connection with the enforcement of any of the Commitment Parties’ rights and
remedies hereunder.
8.    Indemnification. You agree to indemnify and hold harmless each Commitment
Party and its affiliates and each Commitment Party’s and its affiliates’
respective officers, directors, employees, advisors, agents, other
representatives, controlling persons, members, partners and successors and
permitted assigns (each Commitment Party and each such other person being an
“Indemnified Person”) from and against any and all losses, claims, damages,
liabilities and expenses (excluding expenses of the nature described in Section
7 above), joint or several, to which any such Indemnified Person may become
subject arising out of or in connection with this Commitment Letter, the Fee
Letters, the Term Sheets, the Original Commitment Letter, the Original Arranger
Fee Letter, the Transactions and the other transactions contemplated hereby, the
Existing Credit Facility Amendment, the Facilities, the use of proceeds
therefrom and any claim, litigation, investigation or proceeding (any of the
foregoing, a “Proceeding”) relating to any of the foregoing, regardless of
whether any such Indemnified Person is a party thereto and regardless of whether
a Proceeding is brought by a third party or by you, the Target or any of your or
its respective affiliates or equity holders or any other person, and to
reimburse each such Indemnified Person upon demand for any reasonable and
documented out-of-pocket expenses incurred in connection with investigating,
defending or testifying in connection with any of the foregoing (limited, in the
case of legal expenses, to one counsel to the Indemnified Persons taken as a
whole and, if reasonably necessary, one local counsel in each relevant material
jurisdiction and, in the case of a conflict of interest, one additional counsel
(and one additional counsel in each relevant material jurisdiction) to each
group of affected Indemnified Persons similarly situated, taken as a whole;
provided that the foregoing indemnity will not, as to any Indemnified Person,
apply to losses, claims, damages, liabilities or related expenses (a) to the
extent they have been determined in a final, non-appealable judgment of a court
of competent jurisdiction to have resulted primarily from the willful
misconduct, bad faith, fraud or gross negligence of such Indemnified Person, or
material breach by such Indemnified Person of its obligations under this
Commitment Letter or the Loan Documents, or (b) that have resulted from any
dispute solely among or between any of the Commitment Parties not arising from
any act or omission by the Borrower, the Target or their respective affiliates,
other than

--------------------------------------------------------------------------------

any proceeding against an Indemnified Person in its capacity or fulfilling its
role as an administrative agent, arranger, bookrunner, manager, agent or any
other titled role under or in respect of the Facilities or in respect of the
Existing Credit Facility Amendment, provided further that such Indemnified
Person shall promptly repay to you all expense reimbursements previously made
pursuant to this paragraph to the extent that such Indemnified Person is finally
determined by a court of competent jurisdiction not to be entitled to
indemnification hereunder as contemplated by the preceding proviso of this
paragraph. Notwithstanding any other provision of this Commitment Letter, no
Indemnified Person shall be liable for (i) any damages arising from the use by
others of information or other materials obtained through electronic,
telecommunications or other information transmission systems, except to the
extent such damages have been determined in a final, non-appealable judgment of
a court of competent jurisdiction to result from the willful misconduct, bad
faith, fraud or gross negligence of such Indemnified Person, or (ii) any
special, indirect, consequential or punitive damages in connection with its
activities related to this Commitment Letter, the Original Commitment Letter,
the Existing Credit Facility Amendments, the Facilities or the use of proceeds
thereunder.
You shall not be liable for any settlement of any Proceedings effected without
your prior written consent (which consent shall not be unreasonably conditioned,
withheld or delayed), but if settled with your prior written consent or if there
is a judgment by a court of competent jurisdiction in any such Proceedings, you
agree to indemnify and hold harmless each Indemnified Person from and against
any and all losses, claims, damages, liabilities and expenses by reason of such
settlement or judgment in accordance with the preceding paragraph. You shall
not, without the prior written consent of an Indemnified Person (which consent
shall not be unreasonably conditioned, withheld or delayed), effect any
settlement or consent to the entry of any judgment of any pending or threatened
Proceedings in respect of which indemnity could have been sought hereunder by
such Indemnified Person unless such settlement (a) includes an unconditional
release of such Indemnified Person in form and substance satisfactory to such
Indemnified Person from all liability on claims that are the subject matter of
such Proceedings, (b) does not include any statement as to or any admission of
fault, culpability or a failure to act by or on behalf of any Indemnified Person
and (c) contains customary confidentiality and non-disparagement provisions.
Except to the extent arising from your indemnification and expense reimbursement
obligations under this Commitment Letter, the Loan Documents or any other
written agreement to which any such person is a party, in no event shall you,
the Target and your and its respective subsidiaries and affiliates be liable for
special, indirect, consequential or punitive damages.

extent required by law or regulation, in each case to the extent customary, and
(ii) the Fee Letters and the contents thereof on a confidential basis after the
Closing Date to the Borrower’s auditors for customary accounting purposes,
including accounting for deferred financing costs.
Notwithstanding anything herein to the contrary, you (and any employee,
representative or other agent of yours) may disclose to any and all persons,
without limitation of any kind, the tax treatment and tax structure of the
transactions contemplated by this Commitment Letter and the Fee Letters and all
materials of any kind (including opinions or other tax analyses) that are
provided to it relating to such tax treatment and tax structure, except that (a)
tax treatment and tax structure shall not include the identity of any existing
or future party (or any affiliate of such party) to this Commitment Letter or
any Fee Letter and (b) no party shall disclose any information relating to such
tax treatment and tax structure to the extent nondisclosure is reasonably
necessary in order to comply with applicable securities laws. For this purpose,
the tax treatment of the transactions contemplated by this Commitment Letter and
the Fee Letters is the purported or claimed U.S. Federal income tax treatment of
such transactions and the tax structure of such transactions is any fact that
may be relevant to understanding the purported or claimed U.S. Federal income
tax treatment of such transactions.
Each of us agrees that it shall use all material non-public information received
by it in connection with the Acquisition and the other transactions contemplated
by this Commitment Letter solely for the purposes of providing the services that
are the subject of this Commitment Letter and shall treat confidentially all
such information; provided, however, that nothing herein shall prevent any of us
from disclosing any such information (a) to rating agencies on a confidential
basis, (b) to any Existing Lenders, Lenders or participants, prospective Lenders
or participants or

    
12

--------------------------------------------------------------------------------

any direct or indirect contractual counterparties (or prospective
counterparties) to any swap or derivative transaction relating to you or the
other Loan Parties’ and your or their obligations under the Existing Credit
Facility or the Facilities, (c) in any legal, judicial or administrative
proceeding or other compulsory process or otherwise as required by applicable
law or regulations (in which case we agree to, except with respect to any audit
or examination conducted by bank accountants or any governmental bank regulatory
authority exercising examination or regulatory authority, promptly notify you,
such notice to be provided in advance to the extent permitted by applicable
law), (d) upon the request or demand of any regulatory authority having or
purporting to have jurisdiction over any of us or our respective affiliates (in
which case we agree to, except with respect to any audit or examination
conducted by bank accountants or any governmental bank regulatory authority
exercising examination or regulatory authority, promptly notify you to the
extent lawfully permitted to do so), (e) to our respective officers, directors,
agents, employees, attorneys, accountants and advisors (collectively,
“Representatives”) who need to know such information, are informed of the
confidential nature of such information and are or have been advised of their
obligation to keep information of this type confidential, (f) to any of our
respective affiliates and their respective Representatives who need to know such
information, are informed of the confidential nature of such information and are
or have been advised of their obligation to keep information of this type
confidential (provided that we shall be responsible for our respective
affiliates’ compliance with this paragraph), solely in connection with the
Acquisition and the other transactions contemplated by this Commitment Letter,
(g) to the extent any such information becomes publicly available other than by
reason of disclosure by any of us, our respective affiliates or Representatives
in breach of this Commitment Letter, or to the extent any such information is
developed independently by any of us as evidenced by our written records and
without the use of any confidential information, (h) to the extent such
information was already in our possession as evidenced by our written records
prior to any duty or other undertaking of confidentiality entered into in
connection with the Transactions, or otherwise, (i) for purposes of establishing
a “due diligence” defense or in connection with the exercise of any rights or
remedies and (j) to the extent that you have consented in writing prior to such
disclosure; provided that the disclosure of any such information to any Existing
Lenders, any Lenders or prospective Lenders, participants or prospective
participants or derivative counterparties or prospective derivative
counterparties referred to above shall be made subject to the acknowledgment and
acceptance by such Existing Lender, Lender or prospective Lender, participant or
prospective participant or derivative counterparty or prospective derivative
counterparty that such information is being disseminated on a confidential basis
(on substantially the terms set forth in this paragraph or as is otherwise
reasonably acceptable to you and us, including, without limitation, as set forth
in the Existing Credit Facility or as agreed in any confidential information
memorandum or other marketing materials) in accordance with our standard
syndication processes or customary market standards for dissemination of such
type of information. In addition, each Commitment Party may disclose the
existence of the Facilities and the information about the Facilities and the
Existing Credit Facility Amendment to market data collectors, similar services
providers to the lending industry, and service providers to the Commitment
Parties in connection with the administration and management of the Facilities
or the Existing Credit Facility Amendment. Subject to Section 10 hereof, our
obligations under this paragraph shall automatically expire upon the earlier of
execution and delivery of the Loan Documents and the first anniversary of the
date hereof. For the avoidance of doubt, in no event shall any disclosure of
such information referred to above be made to any Disqualified Lender.

in financial and other newspapers and periodicals or on a home page or similar

Commitment Party and its affiliates from other companies.
In connection with all aspects of each transaction contemplated by this
Commitment Letter, you acknowledge and agree, and acknowledge your affiliates’

range of transactions that involve interests that differ from yours and those of
your affiliates, and the Commitment Parties have no obligation to disclose any
of such interests to you or your affiliates. To the fullest extent permitted by
law, you hereby waive and release any claims that you may have against the
Commitment Parties with respect to any breach or alleged breach of agency or
fiduciary duty in connection with any aspect of any financing

    
14

--------------------------------------------------------------------------------

transaction contemplated by this Commitment Letter. No Commitment Party has
provided any legal, accounting, regulatory or tax advice with respect to the
Transactions and the other transactions contemplated by this Commitment Letter
and the Term Sheets and you have consulted with your own legal, accounting,
regulatory and tax advisors to the extent you have deemed it appropriate to do
so.
The parties hereto acknowledge that Goldman, Sachs & Co. has been retained by
you (or one of your affiliates) as financial advisor (in such capacity, the
“Financial Advisor”) in connection with the Acquisition. The parties hereto
agree to such retention, and further agree not to assert any claim they might
allege based on any actual or potential conflicts of interest that might be
asserted to arise or result from the engagement of the Financial Advisor, on the
one hand, and GS Bank’s and its affiliates’ relationships with you as described
and referred to herein, on the other.
10.    Termination. Our commitments and undertakings hereunder shall terminate
in their entirety automatically without further notice or action by us on the
first to occur of (a) November 22, 2017, (b) the date of the closing of the
Acquisition, effective immediately following such closing, with or without the

Agreement in accordance with the terms thereof. Notwithstanding the foregoing,
upon the effectiveness of the Specified Amendment, the commitments and any other
obligations of the Commitment Parties in respect of the Backstop Facility or the
Existing Credit Facility Amendment (or any part thereof) shall permanently,
irrevocably and automatically be terminated and have no further force or effect
without any further action by the Commitment Parties or you.
Notwithstanding anything in this Section 10 to the contrary, the termination of
any commitment pursuant to this Section 10 does not prejudice your or our rights
and remedies in respect of any breach of this Commitment Letter that occurred
prior to such termination.
The Fee Letters and the compensation, reimbursement, indemnification,
syndication, information, jurisdiction, absence of agency or fiduciary
relationship, conflicts of interest, governing law, venue, waiver of jury trial
and confidentiality provisions contained herein shall remain in full force and
effect regardless of whether the Loan Documents shall be executed and delivered
and notwithstanding the termination of this Commitment Letter or any Lender’s
commitments hereunder; provided that your obligations under this Commitment
Letter (other than your obligations with respect to confidentiality,
compensation, jurisdiction, waiver of jury trial, governing law, venue, absence
of agency or fiduciary relationship, conflicts of interest, information and
assistance to be provided in connection with the arrangement and syndication of
the Facilities) shall automatically terminate and be superseded, as to any
Facility, to the extent of any corresponding provisions of the definitive
documentation for such Facility covering substantially the same subject matter
upon the execution and delivery thereof, and you shall automatically be released
from all liability hereunder in connection therewith at such time.
11.    Assignment; etc. This Commitment Letter and the commitments and
undertakings hereunder shall not be assignable by any party hereto without the
prior written consent of each other party hereto, and any attempted assignment
without such consent shall be void and of no effect; provided, however, each
Commitment Party may assign its commitment and other rights and obligations
hereunder, in whole or in part, (a) to any of its affiliates (including, for the

    
15

--------------------------------------------------------------------------------

avoidance of doubt, assignments between GS Bank and GSLP) and (b) subject to
Section 3 hereof, in connection with the syndication of the Facilities or the
arrangement of the Existing Credit Facility Amendment; provided that, other than
as contemplated by Section 3 hereof and except for assignments between GS Bank
and GSLP or assignments to Permitted Lenders, such Commitment Party shall not be
released from the portion of its commitment hereunder so assigned to the extent
such assignee fails to fund the portion of the commitment assigned to it on the
Closing Date notwithstanding the satisfaction of the conditions to such funding
set forth herein. Any assignment in violation of the foregoing shall be null and
void. This Commitment Letter is intended to be solely for the benefit of the
parties hereto and the Indemnified Persons and is not intended to confer any
benefits upon, or create any rights in favor of or be enforceable by, any person
other than the parties hereto and the Indemnified Persons, except that the
Commitment Parties may perform the duties and activities described hereunder
through any of their respective affiliates or branches, including, in the case
of JPMorgan, by or through J.P. Morgan Securities LLC, and the provisions of
Section 9 shall apply with equal force and effect to any of such affiliates or
branches so performing any such duties or activities.
12.    Governing Law; Waiver of Jury Trial; etc. This Commitment Letter and the
Fee Letters shall be governed by and construed in accordance with the laws of
the State of New York without regard to the conflicts of law principles thereof
to the extent that such principles would direct a matter to another
jurisdiction; provided that the laws of the State of Delaware shall govern in
determining (a) whether the Acquisition has been consummated in accordance with
the terms of the Acquisition Agreement, (b) whether a Company Material Adverse
Effect (as defined in Exhibit E) has occurred and (c) accuracy of any
Acquisition Agreement Representations. Each of the parties hereto waives all
right to trial by jury in any action, proceeding or counterclaim (whether based
upon contract, tort or otherwise) related to or arising out of this Commitment
Letter, the Original Commitment Letter, the Fee Letters, the Original Arranger
Fee Letter, each element of the Transactions or the performance by any of us or
any of our respective affiliates of the services contemplated hereby. In
addition, with respect to any action, proceeding or counterclaim arising out of
or relating to this Commitment Letter, the Original Commitment Letter, the Fee
Letters, the Original Arranger Fee Letter, the Transactions or the performance
by any of us or any of our respective affiliates of the services contemplated
hereby, the parties hereto hereby irrevocably: (a) submit to the exclusive
jurisdiction of any New York State or Federal court sitting in the Borough of
Manhattan in the City of New York, New York; (b) agree that, subject to the
final sentence of this paragraph, all claims with respect to such action or
proceeding may be heard and determined exclusively in such New York State or
Federal court; (c) waive the defense of any inconvenient forum to such New York
State or Federal court; (d) agree that a final judgment in any such action or
proceeding shall be conclusive and may be enforced in another jurisdiction by
suit on the judgment or in any other manner provided by law; and (e) consent to
service of process by mailing or delivering a copy of such process to such party
at its address set forth in Section 15 hereof and agree that such service shall
be effective when sent or delivered. Nothing in this Commitment Letter shall
affect any right that any Commitment Party or any of its affiliates may
otherwise have to bring any action or proceeding relating to this Commitment
Letter, the Original Commitment Letter, the Fee Letters, the Original

    
16

--------------------------------------------------------------------------------

Arranger Fee Letter and the Transactions against you or your properties in the
courts of any jurisdiction.
13.    Amendments; Counterparts; etc. No amendment or waiver of any provision
hereof (including the Term Sheets) or of a Fee Letter shall be effective unless
in writing and signed by each of the parties hereto or thereto and then only in
the specific instance and for the specific purpose for which given. This
Commitment Letter (including the Term Sheets) and the Fee Letters are the only
agreements among the parties hereto with respect to the matters contemplated
hereby and thereby and set forth the entire understanding of the parties hereto
with respect thereto. This Commitment Letter may be executed in any number of
counterparts and by different parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement. Delivery of an executed
counterpart of a signature page of this Commitment Letter by facsimile
transmission (or in pdf or similar format by electronic mail) shall be effective
as delivery of a manually executed counterpart of this Commitment Letter.
14.    PATRIOT Act Notification. We hereby notify you that pursuant to the
requirements of the USA PATRIOT Act, Title III of Pub. L. 107-56 (signed into
law October 26, 2001) (as the same may be extended and in effect from time to

Capitalized terms used but not defined in this Exhibit A shall have the meanings
set forth in the Commitment Letter to which this Exhibit A is attached or the
other Exhibits to the Commitment Letter.
Pursuant to the terms of that certain Agreement and Plan of Merger dated as of

Borrower party thereto and the Target (together with all exhibits, schedules and
disclosure letters thereto, collectively, the “Acquisition Agreement”), the
Borrower will acquire the Target (the “Acquisition”).
In connection with the Acquisition, it is intended that:
(a)    The Borrower will (i) on or prior to the Closing Date, (1) issue and sell
senior unsecured notes (the “Senior Notes”) pursuant to a registered public
offering or a Rule 144A and/or Regulation S offering or other private placement
and/or obtain a new syndicated unsecured term loan facility (the “Term Loan
Facility”), with the gross proceeds of such offering of the Senior Notes
together with the aggregated principal amount of the Term Facility not
exceeding, in the aggregate, $2.15 billion, and/or (2) obtain under the Existing
Credit Facility an incremental revolving credit facility in an aggregate
principal amount of up to $1.0 billion, having terms and conditions
substantially as previously discussed by the Borrower and the Amendment Lead
Arrangers with such changes thereto as may be mutually agreed (the “Incremental
Revolving Facility”); or (ii) to the extent that aggregate gross proceeds of
such offering of the Senior Notes received (including into escrow) on or prior
to the Closing Date, together with the aggregate principal amount of the Term
Loan Facility and the Incremental Revolving Facility entered into on or prior to
the Closing Date, in the aggregate, are less than $2.15 billion, obtain up to
$2.15 billion in the aggregate (less the amount of any gross proceeds (including
proceeds received in escrow) from such offering of the Senior Notes and/or the
aggregate principal amount of the Term Loan Facility and/or the Incremental
Revolving Facility), under a senior unsecured bridge credit facility described
in Exhibit B to the Commitment Letter (the “Bridge Facility”).
(b) (i) The Existing Credit Facility will be (x) amended pursuant to the
Specified Amendment and, if the consent of the Existing Lenders thereto is
obtained, the Additional Amendment, in each case, as described in Exhibit C to
the Commitment Letter, or (y) refinanced in full with a senior secured backstop
credit facility described in Exhibit D to the Commitment Letter (the “Backstop
Facility”), with all commitments thereunder terminated and replaced with the
commitments under the Backstop Facility (it being understood that the
commitments under the Backstop Documentation shall not become effective until
the time when the commitments under the Existing Credit Facility shall have
terminated) and all security and guarantees in respect of the Existing Credit
Facility being discharged and released (the “Existing Credit Facility
Refinancing”) and (ii) the following indebtedness of the Target and its
subsidiaries, in each case as amended, will be repaid or otherwise satisfied and
discharged, with all commitments thereunder terminated and

Rate Loan and (b) with respect to each Eurodollar Loan, on the last day of the
applicable interest period relating thereto; provided that in the event that the
interest period for a Eurodollar Loan shall be for a period in excess of three
months, then interest shall also be payable on each three month anniversary of
the commencement of such interest period.

received prior to the Closing Date that would otherwise be subject to the
provisions of this clause (c) shall be subject to such provisions until the

The definitive documentation for the Bridge Facility (the “Bridge
Documentation”) will be based on the Credit Agreement, dated as of September 30,

the terms and conditions set forth in this Exhibit B (as they may be modified in

account for changes in law or accounting standards or to cure mistakes or
defects (it being understood that if a modification of any provision in the
definitive documentation is proposed pursuant to this clause (e), but the
Borrower and the Bridge Lead Arrangers fail to mutually agree on any
modification of such provision in the requisite time period to allow drawing on
the Closing Date, such provision shall be in the form of the corresponding
provision of the Existing Credit Facility). The Bridge Documentation shall
contain only those conditions to borrowing, mandatory prepayments,
representations and warranties, affirmative, negative and financial covenants

without the consent of the Borrower (other than to Disqualified Lenders,
provided that the list thereof is made available to all Bridge Lenders and any
updates to the list thereof shall not be effective until three business days
after such updates are provided to the Bridge Administrative Agent); provided,
however, that, unless an event of default has occurred and is at such time

subsequent thereto, the Commitment Parties would hold, in the aggregate, less
than 50.1% of the outstanding Bridge Loans.

principal, interest (other than default interest) or fees, (c) extension of
final maturity and (d) releases of all or substantially all of the value of the
Guarantees or the Borrower.
Notwithstanding anything in the Bridge Documentation to the contrary, the
Administrative Agent shall not be responsible for monitoring assignments or
participations for compliance with the list of Disqualified Lenders, if any.
Voting:
Amendments and waivers of the Bridge Documentation will require the approval of
the Bridge Lenders holding more than 50% of the aggregate amount of loans and
unused commitments under the Bridge Facility (excluding loans and unused
commitments of Defaulting Lenders) (the “Required Lenders”), except that:
(a) the consent of each Bridge Lender affected thereby shall be required with
respect to (i) increases in commitments, (ii) reductions of principal, interest
(other than default interest) or fees, (iii) extensions of final maturity;
(v) modifications to the pro rata sharing and payment provisions and

Guarantor permitted by the Bridge Documentation) and (b) the consent of 100% of
the Bridge Lenders will be required with respect to (i) modifications to any of
the voting percentages and (ii) releases of the Borrower. The consent of the
Bridge Administrative Agent will be required to amend, modify or otherwise
affect the rights and duties of the Bridge Administrative Agent.
The Bridge Documentation shall contain customary provisions with respect to
non-consenting Bridge Lenders, consistent with the Bridge Documentation
Principles.

foregoing, and hold them harmless from and against all costs, expenses
(including, without limitation, reasonable fees, disbursements and other charges
of counsel) and liabilities of any such indemnified person arising out of or
relating to any claim or any litigation or other proceedings (regardless of
whether any such indemnified person is a party thereto or whether such claim,

Solvency Certificate
Pursuant to Section [•] of the Credit Agreement, dated [•], 2016, among [•] (the
“Borrower”), the Lenders from time to time party thereto and Goldman Sachs Bank
USA, as administrative agent, the undersigned hereby certifies, solely in such
undersigned’s capacity as [Chief Financial Officer] of the Borrower, and not
individually, as follows:
As of the date hereof, after giving effect to the consummation of the
Transactions (as defined in the Credit Agreement), and after giving effect to
the application of the proceeds of such indebtedness under such Transactions:
(a)
The amount of the fair saleable value of the assets of the Borrower and its
Restricted Subsidiaries on a consolidated basis exceeds:

(i)
the value of all liabilities of the Borrower and its Restricted Subsidiaries (on
a consolidated basis), including contingent and other liabilities, as generally
determined in accordance with applicable United States federal laws governing
determinations of the insolvency of debtors; and

(ii)
the amount that will be required to pay the probable liabilities of the Borrower
and its Restricted Subsidiaries on its existing debts (including contingent
liabilities) as such debts become absolute and matured;

(b)
The Borrower and its Restricted Subsidiaries (on a consolidated basis) do not
have an unreasonably small amount of capital for the operation of the businesses
in which it is engaged or proposed to be engaged; and

(c)
The Borrower and its Restricted Subsidiaries (on a consolidated basis) will be
able to pay its liabilities, including contingent and other liabilities, as they
mature.

For purposes of this Certificate, each of the phrases “not have an unreasonably
small amount of capital for the operation of the businesses in which they are
engaged or proposed to be engaged” and “able to pay their liabilities, including
contingent and other liabilities, as they mature” means that the Borrower and
its Restricted Subsidiaries will be able to generate enough cash from
operations, asset dispositions or refinancing, or a combination thereof, to meet
its obligations as they become due. Capitalized terms used but not otherwise
defined herein shall have the meanings assigned to them in the Credit Agreement.
The undersigned is familiar with the business and financial position of the
Borrower and its Restricted Subsidiaries. In reaching the conclusions set forth
in this Certificate, the undersigned has made such other investigations and
inquiries as the undersigned has deemed appropriate, having taken into account
the nature of the particular business anticipated to be conducted by the
Borrower and its Restricted Subsidiaries after consummation of the Transactions.
