“Securities”). The Securities will be issued pursuant to an Indenture to be dated as of November 8, 2012 (the “Indenture”) among the Issuers, Northern Tier Energy LP, a Delaware limited partnership (the “Parent

Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), and Deutsche Bank Trust Company Americas, as collateral agent (the “Collateral Agent”). 
 The Securities will be sold to the Purchasers without being registered under the Securities Act of 1933, as amended (the “Securities Act”), in reliance upon an exemption therefrom. The Issuers
and the Guarantors have prepared a preliminary offering circular dated November 1, 2012 (the “Preliminary Offering Circular”) and will prepare an offering circular dated the date hereof (the “Offering Circular”) setting
forth information concerning the Issuers and the Securities. Copies of the Preliminary Offering Circular have been, and copies of the Offering Circular will be, delivered by the Issuers to the Purchasers pursuant to the terms of this Agreement. Each
of the Issuers hereby confirms that it has authorized the use of the Preliminary Offering Circular, the Pricing Circular (as defined below) and the Offering Circular in connection with the offering and resale of the Securities by the Purchasers in
the manner contemplated by this Agreement. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Preliminary Offering Circular. 

 As of the Time of Delivery (as defined below), the Issuers’ obligations under the
Securities will be fully and unconditionally guaranteed (the “Guarantees”), jointly and severally, (1) on a senior secured basis by each of the Subsidiary Guarantors and (2) on a senior unsecured basis by the Parent Guarantor,
and the Securities and the Guarantees will be secured by a security interest in substantially all present and hereafter acquired tangible and intangible assets of the Issuers and the Subsidiary Guarantors: 

 

	 	(a)	on a first-priority basis, other than in respect of such tangible and intangible assets constituting ABL Priority Collateral (collectively, such assets subject to such
first-priority security interest, the “Notes Priority Collateral”) which Notes Priority Collateral also constitutes collateral securing, on a pari passu basis, (A) the 2017 Notes Obligations, (B) the Pari Passu Lien Hedge
Agreements, and (C) certain other Pari Passu Notes Lien Indebtedness, and which Notes Priority Collateral also constitutes collateral securing, on a second-priority basis, the indebtedness and other obligations arising under the Credit

	 	(b)	on a second-priority basis, in respect of tangible and intangible assets not constituting Notes Priority Collateral (the “ABL Priority Collateral” and,
together with the Notes Priority Collateral, the “Collateral”), which ABL Priority Collateral also constitutes collateral securing, on a pari passu basis, (A) the 2017 Notes Obligations, (B) the Pari Passu Lien Hedge Agreements,
and (C) certain other Pari Passu Notes Lien Indebtedness (as defined in the Pricing Disclosure Package), and which ABL Priority Collateral also constitutes collateral securing, on a first-priority basis, the indebtedness and other obligations
arising under the ABL Facility, in each case, subject to the relative priority of certain other permitted liens. 

The rights of the holders of the Securities with respect to the Collateral are further governed by (x) a Collateral Trust and
Intercreditor Agreement (the “Collateral Trust and Intercreditor Agreement”), dated as of December 1, 2010, among, inter alios, the Issuers, the Subsidiary Guarantors, the Trustee, the Collateral Agent and J. Aron & Company,
as counterparty under the ISDA Master Agreement (the “Hedge Agreement”), dated as of October 6, 2010, between St. Paul Park Refining Co. LLC and J. Aron & Company and the schedules and confirmations in connection therewith,
as such agreement may be amended, restated, modified, supplemented or replaced from time to time, and (y) an Intercreditor Agreement, dated as of December 1, 2010, among, inter alios, the Issuers, the Subsidiary Guarantors, the Collateral
Agent and the ABL Agent (the “ABL Intercreditor Agreement” together with the “Collateral Trust and Intercreditor Agreement,” the “Intercreditor Agreements”). The Trustee, on behalf of the holders of the Securities, will
become party to the Collateral Trust and Intercreditor Agreement as of the Time of Delivery by executing a joinder agreement to the Collateral Trust and Intercreditor Agreement in accordance with the terms thereof (the “Joinder”). The
holders of the Securities will become bound by the ABL Intercreditor Agreement upon delivery, as of the Time of Delivery, of an acknowledgement agreement executed by the Collateral Agent on behalf of the holders of the Securities (the
“Acknowledgement”) in form and substance reasonably satisfactory to the ABL Agent. 
 The portion of the Collateral
(x) constituting Material Real Property (as defined in clause (i) of the definition of “Material Real Property” in the Preliminary Offering Circular) shall be described in the mortgages, deeds of trust or deeds to secure debt to
be dated as of the Time of Delivery, and to be in form and substance reasonably satisfactory to Goldman, Sachs & Co. (collectively, the “Mortgages”), (y) relating to United States trademark applications and registrations,

interest with respect to the Notes Priority Collateral and a second priority interest with respect to the ABL Priority Collateral, in each case, subject to Permitted Exceptions (as defined below), for the benefit of the Trustee, the Collateral Agent
and each holder of the Securities and the successors and assigns of the foregoing.

as “Additional Secured Debt” (as defined in the Collateral Trust and Intercreditor Agreement), and that such Securities are permitted by the Collateral Trust and Intercreditor Agreement and each other applicable “Secured Debt
Document” (as defined in the Collateral Trust and Intercreditor Agreement) to be incurred and secured by a lien equally and ratably with all previously existing and future “Secured Debt” (as defined in the Collateral Trust and
Intercreditor Agreement) and (y) certifies that the Securities and Guarantees constitute “Refinancing Indebtedness” (as defined in the Collateral Trust and Intercreditor Agreement) and satisfy the criteria therefor set forth in the

make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that this representation and warranty shall not apply to statements or omissions made in a Company Supplemental Disclosure
Document in reliance upon and in conformity with information furnished in writing to the Issuers by a Purchaser through the Representatives expressly for use therein.

against such losses and risks as Issuers and the Guarantors believe are adequate to protect their respective businesses; and none of the Issuers or any of the Guarantors has (i) received notice from any insurer or agent of such insurer that
capital improvements or other expenditures are required or necessary to be made in order to continue such insurance or (ii) any reason to believe that it will not be able to renew such existing insurance coverage as and when such coverage
expires or to obtain similar coverage at reasonable cost from similar insurers. 

  

	 	(aaa)	 Immediately after the consummation of the offering of the Securities, the Issuers and each of the Guarantors on a consolidated basis will be Solvent.
As used in this paragraph, the term “Solvent” means, with respect to a particular date, that on such date (i) the present fair market value (or present fair saleable value) of the assets of the Issuers and each of the Guarantors is
not less than the total amount required to pay the liabilities of the Issuers and the Guarantors, as the case may be, on their combined total existing debts and liabilities (including contingent liabilities) as they become absolute and matured;
(ii) the Issuers and the Guarantors are able to realize upon their assets and pay their debts and other liabilities, contingent obligations and 

  
 16 

	 	
commitments as they mature and become due in the normal course of business; (iii) assuming consummation of the issuance of the Securities as contemplated by this Agreement and the use of
proceeds therefrom as described in the Pricing Disclosure Package and the Offering Circular, and the borrowings under the ABL Facility, if any, the Issuers and the Guarantors are not incurring debts or liabilities beyond their ability to pay as such
debts and liabilities mature; (iv) the Issuers and the Guarantors are not engaged in any business or transaction, and do not propose to engage in any business or transaction, for which their property would constitute unreasonably small capital
after giving due consideration to the prevailing practice in the industry in which the Issuers and the Guarantors are engaged; and (v) the Issuers and the Guarantors are not defendants in any civil action that would result in a judgment that
the Issuers and the Guarantors are or would become unable to satisfy. 

  

	 	(bbb)	On the Time of Delivery, no Guarantor will be prohibited, directly or indirectly, under any agreement or other instrument to which it is a party or will be subject,
from paying any dividends to the Issuers, from making any other distribution on such Guarantor’s capital stock or similar ownership interests, from repaying to the Issuers any loans or advances to such Guarantor from the Issuers or from
transferring any of such Guarantor’s properties or assets to the Issuers or any other Guarantor of the Issuers, except (i) to the extent such restriction or prohibition would constitute a Permitted Lien under and as defined in the
Indenture or (ii) as disclosed in the Pricing Disclosure Package and the Offering Circular. 

  

	 	(ccc)	None of the Issuers nor any of the Guarantors is a party to any contract, agreement or understanding with any person (other than this Agreement) that would give rise to
a valid claim against any of them or any Purchaser for a brokerage commission, finder’s fee or like payment in connection with the offering and sale of the Securities.

	 	(g)	On or after the Applicable Time (i) no downgrading shall have occurred in the rating accorded either of the Issuers’ debt securities by any “nationally

liabilities, joint or several, to which such Purchaser may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue
statement or alleged untrue statement of a material fact contained in any Preliminary Offering Circular, the Pricing Circular, the Offering Circular, or any amendment or supplement thereto, any Company Supplemental Disclosure Document, or arise out
of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and will reimburse each Purchaser for any
documented legal or other expenses reasonably incurred by such Purchaser in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Issuers and the Guarantors shall not be liable
in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Offering Circular, the Pricing
Circular, the Offering Circular or any such amendment or supplement, or any Company Supplemental Disclosure Document, in reliance upon and in conformity with written information furnished to the Issuers by any Purchaser through the Representatives
expressly for use therein. 

  

	 	(b)	Each Purchaser will indemnify and hold harmless the Issuers and the Guarantors (each, an “Issuer Indemnified Party”) against any losses, claims, damages or
liabilities to which such Issuer Indemnified Party becomes subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or
alleged untrue statement of a material fact contained in any Preliminary Offering Circular, the Pricing Circular, the Offering Circular, or any amendment or supplement thereto, or any Company Supplemental Disclosure Document, or arise out of or are
based upon the omission or alleged omission to state therein a material fact or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any Preliminary Offering Circular, the Pricing Circular, the Offering Circular or any such amendment or supplement, or any Company
Supplemental Disclosure Document in reliance upon and in conformity with written information furnished to the Issuers by such Purchaser through the Representatives expressly for use therein; and will reimburse the Issuer Indemnified Party for any
legal or other expenses reasonably incurred by the Issuer Indemnified Party in connection with investigating or defending any such action or claim as such expenses are incurred. 

 

	 	(c)	 Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such
indemnified party shall, if a claim in respect thereof is to be 

  
 24 

	 	
made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not
relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement
thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the
indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense
thereof other than reasonable costs of investigation. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or
threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment
(i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf
of any indemnified party. An indemnifying party shall not be required to indemnify an indemnified party for any amount paid or payable by the indemnified party in the settlement of any action, proceeding or investigation without the written consent
of the indemnifying party, which consent shall not be unreasonably withheld. Notwithstanding the foregoing sentence, if at any time (i) an indemnified party enters into a settlement of a proceeding without the consent of the indemnifying party
and (ii) an indemnified party shall have requested the indemnifying party to reimburse the indemnified party for fees and expenses of counsel such indemnifying party is obligated to pay pursuant to subsections (a) and (b) above and
the second sentence of this subsection (c) with respect to such proceeding, then the indemnifying party agrees that it shall be liable for such settlement if it shall not have reimbursed the indemnified party for such fees and expenses in
accordance with such request within 60 days of such request. 

  

	 	(d)	 If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under subsection
(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Issuers and the Guarantors on the one hand and the Purchasers on the other
from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) above, then
each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuers and the Guarantors on the
one hand and the Purchasers on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The
relative benefits received by the Issuers and the Guarantors on the one hand and the 

  
 25 

	 	
Purchasers on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Issuers bear to the total discounts
and commissions received by the Purchasers, in each case as set forth in the Offering Circular. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information supplied by the Issuers or any of the Guarantors on the one hand or the Purchasers on the other and the parties’ relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The Issuers, the Guarantors and the Purchasers agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation
(even if the Purchasers were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Purchaser shall be required to contribute any amount in excess of the amount by which the total price at which
the Securities purchased by it and distributed to investors were offered to investors exceeds the amount of any damages which such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or
alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Purchasers’
obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint. 

  

	 	(e)	The obligations of the Issuers and each of the Guarantors under this Section 9 shall be in addition to any liability which each of the Issuers and each of the
Guarantors may otherwise have and shall extend, upon the same terms and conditions, to any affiliate of each Purchaser and each person, if any, who controls any Purchaser within the meaning of the Securities Act; and the obligations of the
Purchasers under this Section 9 shall be in addition to any liability which the respective Purchasers may otherwise have and shall extend, upon the same terms and conditions, to each officer, director and member of the Issuers and the
Guarantors and to each person, if any, who controls the Issuers and the Guarantors within the meaning of the Securities Act. 

  

	10.	(a) If any Purchaser shall default in its obligation to purchase the Securities which it has agreed to purchase hereunder, you may in your discretion arrange for you or
another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Purchaser you do not arrange for the purchase of such Securities, then the Issuers shall be entitled to a
further period of thirty-six hours within which to procure another party or other parties satisfactory to you to purchase such Securities on such terms. In the event that, within the respective prescribed periods, you notify the Issuers that you
have so arranged for the purchase of such Securities, or the Issuers notify you that it has so arranged for the purchase of such Securities, you or the Issuers shall have the right to postpone the Time of Delivery for a period of not more than seven
days, in order to effect whatever changes may thereby be made necessary in the Offering Circular, or in any other documents or arrangements, and the Issuers agree to prepare promptly any amendments to the Offering Circular which in your opinion may
thereby be made necessary. The term “Purchaser” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such
Securities. 

  
 26 

	 	(b)	If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Purchaser or Purchasers by you and the Issuers as provided in subsection
(a) above, the aggregate principal amount of such Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all the Securities, then the Issuers shall have the right to require each non-defaulting
Purchaser to purchase the principal amount of Securities which such Purchaser agreed to purchase hereunder and, in addition, to require each non-defaulting Purchaser to purchase its pro rata share (based on the principal amount of Securities which
such Purchaser agreed to purchase hereunder) of the Securities of such defaulting Purchaser or Purchasers for which such arrangements have not been made; but nothing herein shall relieve a defaulting Purchaser from liability for its default.

  

	 	(c)	If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Purchaser or Purchasers by you and the Issuers as provided in subsection
(a) above, the aggregate principal amount of Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of all the Securities, or if the Issuers shall not exercise the right described in subsection
(b) above to require non-defaulting Purchasers to purchase Securities of a defaulting Purchaser or Purchasers, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Purchaser or the Issuers and the
Guarantors, except for the expenses to be borne by the Issuers and the Guarantor and the Purchasers as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a
defaulting Purchaser from liability for its default. 

  

	11.	The respective indemnities, agreements, representations, warranties and other statements of each of the Issuers, each of the Guarantors and the several Purchasers, as
set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any
Purchaser or any controlling person of any Purchaser, each of the Issuers, any Guarantor, or any officer, member or director or controlling person of the Issuers or of any of the Guarantors, and shall survive delivery of and payment for the
Securities. 

  

	12.	If this Agreement shall be terminated pursuant to Section 10 hereof, the Issuers and the Guarantors shall not then be under any liability to any Purchaser except
as provided in Sections 7 and 9 hereof; but, if for any other reason, the Securities are not delivered by or on behalf of the Issuers as provided herein, the Issuers and the Guarantors jointly and severally agree to reimburse the Purchasers through
you for all expenses approved in writing by you, including fees and disbursements of counsel, reasonably incurred by the Purchasers in making preparations for the purchase, sale and delivery of the Securities, but the Issuers and the Guarantors
shall then be under no further liability to any Purchaser except as provided in Sections 7 and 9 hereof. 

  

	13.	In all dealings hereunder, you shall act on behalf of each of the Purchasers, and the parties hereto shall be entitled to act and rely upon any statement, request,
notice or agreement on behalf of any Purchaser made or given by you. 

  

	14.	 All statements, requests, notices and agreements hereunder shall be in writing, and if to the Purchasers shall be delivered or sent by mail, telex or
facsimile transmission to Goldman, Sachs & Co. on behalf of 

  
 27 

	 	
the Representatives in care of Goldman, Sachs & Co., 200 West Street, New York, New York 10282-2198, Attention: Registration Department; Deutsche Bank Securities Inc., 60 Wall Street,
New York, New York 10005, Attention: Leveraged Debt Capital Markets, with a copy at the same address to the attention of the General Counsel, 36th Floor; J.P. Morgan Securities LLC, 383 Madison Avenue, New York, New York 10179, and if to either of
the Issuers shall be delivered or sent by mail, telex or facsimile transmission to the address of the Issuer set forth in the Offering Circular, Attention: Secretary; provided, however, that any notice to a Purchaser pursuant to Section 9(c)
hereof shall be delivered or sent by mail, telex or facsimile transmission to such Purchaser at its address set forth in its Purchasers’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Issuers by
you upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof. 

  

	15.	In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Purchasers are required to obtain,
verify and record information that identifies their respective clients, including each of the Issuers and the Guarantors, which information may include the name and address of their respective clients, as well as other information that will allow
the Purchasers to properly identify their respective clients. 

  

	16.	This Agreement shall be binding upon, and inure solely to the benefit of, the Purchasers, each of the Issuers and the Guarantors and, to the extent provided in Sections
9 and 11 hereof, the officers, members and directors of each of the Issuers and the Guarantor, any affiliate of each Purchaser, and each person who controls either of the Issuers, any Guarantor or any Purchaser, and their respective heirs,
executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement. No purchaser of any of the Securities from any Purchaser shall be deemed a successor or assign by reason
merely of such purchase. 

  

	17.	Time shall be of the essence of this Agreement. 

  

	18.	Each of the Issuers acknowledges and agrees that (i) the purchase and sale of the Securities and the Guarantees pursuant to this Agreement is an arm’s-length
commercial transaction between the Issuers and the Guarantors, on the one hand, and the several Purchasers, on the other, (ii) in connection therewith and with the process leading to such transaction each Purchaser is acting solely as a
principal and not the agent or fiduciary of either of the Issuers or the Guarantors, (iii) no Purchaser has assumed an advisory or fiduciary responsibility in favor of either of the Issuers or any Guarantor with respect to the offering
contemplated hereby or the process leading thereto (irrespective of whether such Purchaser has advised or is currently advising the Issuers or the Guarantors on other matters) or any other obligation to the Issuers or the Guarantors except the
obligations expressly set forth in this Agreement and (iv) each of the Issuers and the Guarantors has consulted its own legal and financial advisors to the extent it deemed appropriate. Each of the Issuers and the Guarantors agrees that it will
not claim that the Purchaser, or any of them, has rendered advisory services of any nature or respect, or owes a fiduciary or similar duty to either of the Issuers or the Guarantors, in connection with such transaction or the process leading
thereto. 

  

	19.	This Agreement supersedes all prior agreements and understandings (whether written or oral) among Issuers and the Guarantors, singly or together, and the Purchasers, or
any of them, with respect to the subject matter hereof. 

  
 28 

	20.	THIS AGREEMENT AND ANY MATTERS RELATED TO THIS TRANSACTION SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO
PRINCIPLES OF CONFLICT OF LAWS THAT WOULD RESULT IN THE APPLICATION OF ANY LAW OTHER THAN THE LAWS OF THE STATE OF NEW YORK. Each of the Issuers and the Guarantors agrees that any suit or proceeding arising in respect of this agreement or our
engagement will be tried exclusively in the U.S. District Court for the Southern District of New York or, if that court does not have subject matter jurisdiction, in any state court located in The City and County of New York and the Issuers and
the Guarantors agree to submit to the jurisdiction of, and to venue in, such courts. 

  

	21.	Each of the Issuers and the Guarantors and each of the Purchasers hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to
trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. 

  

	22.	This Agreement may be executed by any one or more of the parties hereto in any number of counterparts, each of which shall be deemed to be an original, but all such
respective counterparts shall together constitute one and the same instrument. 

  

	23.	Notwithstanding anything herein to the contrary, each of the Issuers and the Guarantors (and the employees, representatives, and other agents of each of the Issuers and
the Guarantors) are authorized to disclose to any and all persons, the tax treatment and tax structure of the potential transaction and all materials of any kind (including tax opinions and other tax analyses) provided to the Issuers and the
Guarantors relating to that treatment and structure, without the Purchasers’ imposing any limitation of any kind. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence
shall not apply) to the extent reasonably necessary to enable any person to comply with applicable securities laws. For this purpose, “tax treatment” means US federal and state income tax treatment, and “tax structure” is limited
to any facts that may be relevant to that treatment. 

 If the foregoing is in accordance with your understanding, please sign and
return to us one for each of the Issuers and the Representatives plus one for each counsel counterparts hereof, and upon the acceptance hereof by you, on behalf of each of the Purchasers, this letter and such acceptance hereof shall constitute a
binding agreement between each of the Purchasers and each of the Issuers and Guarantors. It is understood that your acceptance of this letter on behalf of each of the Purchasers is pursuant to the authority set forth in a form of Agreement among
Purchasers, the form of which shall be submitted to the Issuers for examination upon request, but without warranty on your part as to the authority of the signers thereof.

 Exhibit A 
 Form of Vinson & Elkins LLP Opinion 
 This opinion letter is provided to
you pursuant to Section 8(b) of that certain Purchase Agreement, dated November    , 2012 (the “Purchase Agreement”), entered into by and among Northern Tier Energy LLC, a Delaware limited liability company
(the “Company”), Northern Tier Finance Corporation, a Delaware corporation (the “Co-Issuer,” and together with the Company, the “Issuers”), Northern Tier Energy LP, a Delaware limited partnership
(“Parent Guarantor”), St. Paul Park Refining Co. LLC, a Delaware limited liability company (“SPPR”), Northern Tier Bakery LLC, a Delaware limited liability company (“NTB”), Northern Tier Oil
Transport LLC, a Delaware limited liability company (“NTOT”), Northern Tier Retail LLC, a Delaware limited liability company (“NTR”), SuperAmerica Franchising LLC, a Delaware limited liability company
(“SAF”), and Northern Tier Retail Holdings LLC, a Delaware limited liability company (“NTRH,” and, together with, SPPR, NTB, NTOT, NTR and SAF, the “Subsidiary Guarantors”; the Subsidiary Guarantors
together with Parent Guarantor, the “Guarantors”), and the several initial purchasers named in Schedule I thereto (the “Purchasers”). As used herein, the Issuers and the Guarantors are collectively referred to as
the “NTE Parties.” 
 The Issuers propose to issue and sell to the Purchasers $275,000,000 aggregate principal
amount of their    % Senior Secured Notes due 2020 (the “Securities”). The Securities will be issued pursuant to that certain Indenture, dated the date hereof (the “Indenture”), entered into by
and among the Issuers, the Guarantors, Deutsche Bank Trust Company Americas, as trustee (the “Trustee”) and as collateral agent (the “Collateral Agent”), and will be fully and unconditionally guaranteed, jointly and
severally, (1) on a senior secured basis by each of the Subsidiary Guarantors and (2) on a senior unsecured basis by the Parent Guarantor. 
 Capitalized terms used but not defined herein shall have the meanings ascribed thereto in the Purchase Agreement. 
 We have acted as counsel for the NTE Parties in connection with the issuance and sale by the Issuers of the Securities. In connection with the opinions set forth below, we have reviewed and relied on
originals or copies, certified or otherwise identified to our satisfaction of each of the following: 
  

	 	(a)	an executed copy of the Purchase Agreement; 

  

	 	(b)	an executed copy of the Indenture, including the guarantees of the Securities set forth in the Indenture (the “Guarantees”): 

 

	 	(c)	an executed copy of that certain Exchange and Registration Rights Agreement, dated the date hereof (the “Registration Rights Agreement”), entered into
by and among the Issuers, the Guarantors and the Purchasers; 

  

	 	(d)	an executed copy of (i) each of Intercreditor Agreements, (ii) the Lien Sharing and Priority Confirmation, (iii) the Subordination and Priority
Agreement, (iv) the Joinder, (v) the Acknowledgement, (vi) the Intercreditor Officer’s Certificate, and (vii) each of the Collateral Documents (clauses (i) through (vii) together with the Purchase Agreement, the
Indenture, the Securities, the Exchange Securities and the Registration Rights Agreement, the “Operative Documents”); 

  

	 	(e)	a copy of each of the certificates representing the Securities in global form, as executed by the Issuers and authenticated by the Trustee; 

	 	(f)	the Preliminary Offering Circular dated November 1, 2012; 

  

	 	(g)	the Pricing Supplement dated November    , 2012; 

  

	 	(h)	the Offering Circular dated November    , 2012; and 

  

	 	(i)	such other documents and records as we have deemed necessary or advisable for purposes of the opinions set forth below. 

Based on the foregoing, and subject to the assumptions, qualifications and limitations set forth herein, we are of the opinion that:

  

	 	1.	Each of the NTE Parties has been duly formed and is validly existing and in good standing as a corporation, limited partnership or limited liability company, as
applicable, under the laws of the State of Delaware, with power and authority (corporate, limited partnership or limited liability company, as the case may be, and other) to (x) own or lease their respective properties and conduct their
respective businesses in all material respects as described in the Pricing Disclosure Package and the Offering Circular; and (y) enter into each of the Operative Documents to which it is a party and to perform its obligations thereunder. Each
of the NTE Parties has been duly qualified to transact business in, and is in good standing as a limited liability company or limited partnership, as the case may be, in each foreign jurisdiction, if applicable, set forth in Annex B attached
hereto. 

  

	 	2.	Northern Tier Energy GP LLC, a Delaware limited liability company (“General Partner”), owns the sole general partner interest in Parent Guarantor. Such
general partner interest has been duly authorized and validly issued in accordance with the First Amended and Restated Agreement of Limited Partnership of Parent Guarantor (the “Partnership Agreement”). General Partner owns such
interest free and clear of all liens, encumbrances, equities or claims: (A) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming General Partner as debtor is on file in the office of the
Secretary of State of the State of Delaware or (B) otherwise known to us, without independent investigation, other than (1) restrictions on transferability contained in the Partnership Agreement or as described Pricing Disclosure Package
or the Offering Circular and (2) liens created by or arising under the Delaware Revised Uniform Limited Partnership Act (the “Delaware LP Act”); 

 

	 	3.	Parent Guarantor owns 99.9% of the issued and outstanding member interests in the Company; such member interests have been duly authorized and validly issued in

 In rendering the opinion expressed in paragraph (1) above concerning
“good standing,” we have relied solely on the review of “good standing” certificates of public officials. In rendering our opinion in paragraph (1) as to the due qualification or registration as a foreign limited partnership
or limited liability company, as the case may be, of the NTE Parties, we have relied solely on certificates of foreign qualification or registration provided by the Secretary of State of the states listed on Annex B attached hereto;

 With respect to the opinion set forth in paragraphs (8), (9), (10), (11) and (12) above, we express no opinion as
to the enforceability of any provisions relating to: (a) any failure to comply with requirements concerning notices, relating to delay or omission to enforce rights or remedies or purporting to waive or affect rights, claims, defenses or other
benefits to the extent that any of the same cannot be waived or so affected under applicable law; (b) indemnities or exculpation from liability to the extent prohibited by federal or state laws and the public policies underlying those laws or
that might require indemnification for, or exculpation from liability on account of, gross negligence, willful misconduct, unlawful acts, fraud or illegality of an indemnified or exculpated party; (c) requirements that all amendments, waivers

 In rendering the opinion expressed in sub-paragraph (i) of paragraph (12) above concerning

With respect to the opinion set forth in paragraph (19) above, we express no opinion as to any subsequent reoffer or resale of any

 The foregoing opinions are limited to matters involving the federal laws of the United States of America
to the extent specifically referred to herein, the laws of the State of New York (excluding rules, regulations and ordinances of counties, towns, municipalities and other special political subdivisions of the State of New York), the DGCL, the
Delaware LLC Act and the Delaware LP Act. 
 In addition, we have participated in conferences with officers and other
representatives of the NTE Parties, with the independent public accountants for the NTE Parties, and with representatives of, and counsel to, the Purchasers, at which conferences the contents of the Preliminary Offering Circular, the Pricing
Disclosure Package and the Offering Circular and related matters were discussed, and we reviewed certain corporate records and documents furnished to us by the NTE Parties. 

 Although we have not independently verified and are not passing upon, and are not assuming
any responsibility for, or undertaking to determine independently, the accuracy, completeness or fairness of the statements contained in the Pricing Disclosure Package and the Offering Circular (except as expressly provided in the previous opinion
paragraphs (15) and (16)), based on the foregoing (relying with respect to factual matters to the extent we deem appropriate upon statements by officers and other representatives of the NTE Parties and the Purchasers), nothing has come to our
attention that lead us to believe that: 
  

	 	(A)	the Pricing Disclosure Package (other than the financial statements or notes thereto and the auditor’s report thereon included or incorporated by reference in the
Pricing Disclosure Package or other financial data included or incorporated by reference in or omitted from the Pricing Disclosure Package, as to which we express no view, belief or comment), as of the Applicable Time, contained any untrue statement
of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; or 

 

	 	(B)	the Offering Circular (other than the financial statements or notes thereto and the auditor’s report thereon included or incorporated by reference in the Offering
Circular or other financial data included or incorporated by reference in or omitted from the Offering Circular, as to which we express no view, belief or comment), as of its issue date and as of the date hereof, contained or contains any untrue
statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. 

This opinion letter is furnished to the Purchasers in connection with the transactions contemplated by the Purchase Agreement and is
solely for the benefit of the Purchasers in connection with such transactions and may not be relied upon by any other person or entity or furnished to anyone else or relied upon for any other purpose without our prior written consent, except that

occurring subsequent to the date hereof that might affect any of the matters covered by this opinion letter.

and Northern Tier Finance Corporation, a Delaware corporation (the “Co-Issuer,” and together with the Company, the “Issuers”) in connection with the sale of the Issuers’ 7.125% Senior Secured Notes due 2020 (the
“Notes”) pursuant to Rule 144A and Regulation S under the Securities Act of 1933, as amended (the “Securities Act”). This opinion is being delivered pursuant to Section 8(c) of the Purchase Agreement, dated
November 2, 2012, (the “Purchase Agreement”) among the Issuers, the guarantors named therein and you relating to the Notes. Capitalized terms used herein and not defined herein have the meanings assigned to them in the Purchase

 We have
not examined any other documents. Except for rendering this opinion letter and any collateral opinion letters in conjunction with the issuance of the Notes, we have not participated in any aspects of the transactions or any of the actions
contemplated by the Purchase Agreement. Accordingly, we have assumed that all parties to the Operative Documents have acted and will act in accordance with, and will refrain from taking any action that is forbidden by, the terms and conditions of
the Operative Documents. We have also reviewed such questions of law as we have considered necessary and appropriate for the purposes of our opinions set forth below. 
 In rendering our opinions set forth below, we have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures and the conformity to authentic originals of
all documents submitted to us as copies. We have also assumed the legal capacity for all purposes relevant hereto of all natural persons and, with respect to all parties to 

 
agreements or instruments relevant hereto, that such parties had the requisite power and authority (corporate or otherwise) to execute, deliver and perform such agreements or instruments, that
such agreements or instruments have been duly authorized by all requisite action (corporate or otherwise), executed and delivered by such parties and that such agreements or instruments are the valid, binding and enforceable obligations of such
parties. As to questions of fact material to our opinions, we have relied upon the representations made in the Purchase Agreement and upon certificates of officers of the Company and of public officials (including, without limitation, those
certificates delivered to others at the closing). 
 Based on the foregoing, we are of the opinion that:

application of the proceeds therefrom as described under “Use of Proceeds” in the Pricing Disclosure Package and the Offering Circular, (C) the execution and delivery of the Operative Documents by the Issuers, the Parent Guarantor and
the Subsidiary Guarantors party thereto or (D) the consummation of the Intercreditor Requirements and the transactions contemplated by any Operative Document will result in any violation of any Generally Applicable Law or Other Specified Law,
except for such conflicts, breaches, violations, defaults, liens, charges or encumbrances as would not, individually or in the aggregate, reasonably be expected (A) to have a Material Adverse Effect or (B) to have a material adverse effect
on the ability of the Issuers, the Parent Guarantor or the Subsidiary Guarantors to consummate the transactions contemplated by any Operative Document; and 
 (ii) No consent, approval, authorization or order of or registration, qualification or filing with any Minnesota court or governmental agency or body (including regulatory bodies) is required under any
Generally Applicable Law or Other Specified Law for the execution and delivery by any of the Issuers, the Parent Guarantor or the Subsidiary Guarantors of the Operative Documents to which they are party, the consummation of the Intercreditor
Requirements and the transactions contemplated by any Operative Document by the Issuers, the Parent Guarantor or the Subsidiary Guarantors, or the issuance and sale of the Notes by the Issuers pursuant to the Purchase Agreement and the application
of the proceeds therefrom as described under “Use of Proceeds” in the Pricing Disclosure Package and the Offering Circular, except for such consents, approvals, authorizations, orders, registrations, qualifications or filings as may be
required under state securities or Blue Sky laws in connection with the purchase and distribution of the Notes. 
 The term “Generally
Applicable Law” means any present statute, rule or regulation of the State of Minnesota that a lawyer in such state exercising customary professional diligence would reasonably recognize as being directly applicable to general business
organizations that are not engaged in regulated business activities and to transactions of the type effected pursuant to the Operative Documents (other than the laws identified in exception (b) below), and the term “Other Specified
Laws” means any present statute, rule or regulation of the State of Minnesota that is part of a regulatory regime specifically applicable to pipelines, public utilities, public service corporations or common carriers. 

 The opinions set forth above are subject to the following qualifications and exceptions:

 (b) Our opinions are subject to the effect of any applicable bankruptcy, insolvency, reorganization,
moratorium or other similar law of general application affecting creditors’ rights, including (without limitation) applicable fraudulent transfer laws. 

(c) The opinions expressed above do not address any of the following legal issues: (i) securities laws and
regulations and laws and regulations relating to commodity (and other) futures and indices and other similar instruments; (ii) pension and employee benefit laws and regulations; (iii) antitrust and unfair competition laws and regulations;

regional level) and judicial decisions to the extent that they deal with the foregoing; (v) environmental laws and regulations; (vi) land use and subdivision laws and regulations; (vii) tax laws and regulations;
(viii) intellectual property laws and regulations; (ix) racketeering laws and regulations; (x) health and safety laws and regulations; (xi) labor laws and regulations; (xii) laws, regulations and policies concerning national

and wire fraud statutes). 
 Our opinions expressed above are limited to the law of the State of Minnesota.

 ANNEX I 
  

	(1)	The Securities have not been and will not be registered under the Securities Act and may not be offered or sold within the United States or to, or for the account or
benefit of, U.S. persons except in accordance with Regulation S under the Securities Act or pursuant to an exemption from the registration requirements of the Securities Act. Each Purchaser represents that it has offered and sold the Securities, and
will offer and sell the Securities (i) as part of their distribution at any time and (ii) otherwise until 40 days after the later of the commencement of the offering and the Time of Delivery, only in accordance with Rule 903 of Regulation

it and they have complied and will comply with the offering restrictions requirement of Regulation S. Each Purchaser agrees that, at or prior to confirmation of sale of Securities (other than a sale pursuant to Rule 144A), it will have sent to each
distributor, dealer or person receiving a selling concession, fee or other remuneration that purchases Securities from it during the restricted period a confirmation or notice to substantially the following effect: 

“The Securities covered hereby have not been registered under the U.S. Securities Act of 1933 (the “Securities Act”) and
may not be offered and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the commencement of the offering
and the closing date, except in either case in accordance with Regulation S (or Rule 144A if available) under the Securities Act. Terms used above have the meaning given to them by Regulation S.” 

Terms used in this paragraph have the meanings given to them by Regulation S. 

Each Purchaser further agrees that it has not entered and will not enter into any contractual arrangement with respect to the distribution
or delivery of the Securities, except with its affiliates or with the prior written consent of the Issuer. 
  

	(2)	Notwithstanding the foregoing, Securities in registered form may be offered, sold and delivered by the Purchasers in the United States and to U.S. persons pursuant
to Section 3 of this Agreement without delivery of the written statement required by paragraph (1) above. 

  

	(3)	Each Purchaser agrees that it will not offer, sell or deliver any of the Securities in any jurisdiction outside the United States except under circumstances that will
result in compliance with the applicable laws thereof, and that it will take at its own expense whatever action is required to permit its purchase and resale of the Securities in such jurisdictions. Each Purchaser understands that no action has been
taken to permit a public offering in any jurisdiction outside the United States where action would be required for such purpose. Each Purchaser agrees not to cause any advertisement of the Securities to be published in any newspaper or periodical or

 ANNEX II 
 We have audited: 
  

	1.	the consolidated financial statements of Northern Tier Energy LLC (the “Issuer”) and subsidiaries as of December 31, 2011 and 2010, for the year ended
December 31, 2011 and for the period from June 23, 2010 (date of inception) to December 31, 2010; and 

  

	2.	the combined financial statements of St. Paul Park Refinery Business and the Retail Marketing Business (the “Predecessor Company”) for the eleven months ended
November 30, 2010 and the year ended December 31, 2009. 

 The consolidated financial statements and combined financial
statements referred to above all are included in the preliminary offering circular dated October 31, 2012 (the “Offering Circular”) for $275,000,000 of 7.125% Senior Secured Notes due 2019 (the “Senior Debt”). Our reports
with respect thereto also are included in the Offering Circular. 
 This letter is being furnished in reliance upon your representation to us
that: 
  

	a.	You are knowledgeable with respect to the due diligence review process that would be performed if this placement of securities were being registered pursuant to the
Securities Act of 1933 (the “Act”). 

  

	b.	In connection with the offering of Senior Debt, the review process you have performed is substantially consistent with the due diligence review process that you would
have performed if this placement of securities were being registered pursuant to the Act. 

 In connection with the Offering
Circular: 
  

	1.	We are an independent registered public accounting firm with respect to (i) Northern Tier Energy LP, (ii) the Issuer and (iii) the Predecessor Company
within the applicable rules and regulations adopted by the Securities and Exchange Commission (“SEC”) and the Public Company Accounting Oversight Board (United States) (“PCAOB”). 

 

	2.	Issuer officials have advised us that the financial statements included or incorporated by reference in the Offering Circular are prepared in accordance with Regulation
S-X of the SEC. In our opinion, the consolidated financial statements of the Issuer and the combined financial statements of the Predecessor Company audited by us and included or incorporated by reference in the Offering Circular comply as to form
in all material respects with the applicable sections of Regulation S-X of the SEC. 

  

	3.	We have not audited any financial statements of the Issuer as of any date or for any period subsequent to December 31, 2011; although we have conducted an audit
for the year ended December 31, 2011, the purpose (and therefore the scope) of such audit was to enable us to express an opinion on the consolidated financial statements as of and for the year ended December 31, 2011, but not on the
financial statements for any interim period within the year ended December 31, 2011. Therefore, we are unable to and do not express any opinion on the unaudited condensed consolidated balance sheet and the unaudited condensed consolidated
statements of operations and comprehensive income (loss) and of cash flows included in the Issuer’s quarterly reports on Form 10-Q for the quarters ended March 31, 2012 and June 30, 2012, included or incorporated by reference in the
Offering Circular, or on the financial position, results of operations or cash flows as of any date or for any period subsequent to December 31, 2011. 

 We have not audited any financial statements of the Predecessor Company as of any date or for any period subsequent to November 30, 2010. Therefore, we are unable to and do not express any opinion on
the financial position, results of operations or cash flows of the Predecessor Company as of any date or for any period subsequent to November 30, 2010. 

	4.	For purposes of this letter, we have read the minutes of the 2012 meetings of the stockholders, the Board of Directors and the Audit Committee of the Issuer and its
subsidiaries as set forth in the minute books at October 31, 2012, officials of the Issuer having advised us that the minutes of all such meetings through that date were set forth therein (except for the minutes of the October 15, 2012
Special Meeting of the Board of Directors, the September 5, 2012 Audit Committee Meeting, and the October 15, 2012 Compensation Committee Meeting all of which were not approved in final form, for which draft minutes were provided to us),
and have carried out other procedures to October 31, 2012 (our work did not extend to the period from November 1, 2012 to November 2, 2012, inclusive) as follows: 

 

	 	a.	With respect to the three-month periods ended March 31, 2012 and 2011 and the three- and six-month periods ended June 30, 2012 and 2011 for the Issuer and the
three- and six-month periods ended June 30, 2012 and 2011 for Northern Tier Energy LP, we have: 

  

	 	(i)	performed the procedures (completed on May 29, 2012 and August 9, 2012 for the Issuer and completed on September 7, 2012 for Northern Tier Energy LP)
specified by the PCAOB for a review of interim financial information as described in PCAOB AU 722 Interim Financial Information, on the unaudited condensed consolidated balance sheet as of March 31, 2012, and unaudited condensed
consolidated statements of operations and comprehensive income (loss) and of cash flows for the three-month period ended March 31, 2012 and 2011 and the unaudited condensed consolidated balance sheet as of June 30, 2012, and unaudited
condensed consolidated statements of operations and comprehensive income (loss) and of cash flows for the three- and six-month periods ended June 30, 2012 and 2011 included or incorporated by reference in the Offering Circular; and

  

	 	(ii)	inquired of certain officials of the Issuer who have responsibility for financial and accounting matters whether the unaudited condensed consolidated financial
statements referred to in 4.a.(i) above comply as to form in all material respects with the applicable section of Regulations S-X of the SEC. 

  

	 	b.	With respect to the period from July 1, 2012 to August 31, 2012 for the Issuer, we have: 

 

	 	(i)	read the unaudited consolidated financial data of the Issuer and subsidiaries for July and August of 2012 and 2011 furnished to us by the Issuer, and agreed the amounts
contained therein with the Issuer’s accounting records. Officials of the Issuer have advised us that (1) the July and August of both 2012 and 2011 data was not prepared in accordance with generally accepted accounting principles as it does
not reflect the application of the following generally accepted accounting principle: the recording of the initial deferred tax impact associated with the change in status for federal income tax purposes and any subsequent income tax provisions, and
(2) no financial data as of any date or for any period subsequent to August 31, 2012 for the Issuer were available. Additionally, the financial information for July and August of 2012 and 2011 of the Issuer is incomplete in that it omits
the statement of cash flows and other disclosures, and 

  

	 	(ii)	inquired of certain officials of the Issuer who have responsibility for financial and accounting matters as to whether (1) the unaudited consolidated financial
data referred to in 4.b.(i) are stated on a basis substantially consistent with that of the audited consolidated financial statements included in the Offering Circular; (2) at August 31, 2012 there was any increase in long-term debt, or
decrease in consolidated net current assets (working capital) or member’s interest of the Issuer and consolidated subsidiaries as compared with amounts shown in the June 30, 2012 unaudited condensed consolidated balance sheet included in
the Offering Circular; and (3) for the period from July 1, 2012 to August 31, 2012, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated revenues or net income (loss).

 Those officials stated that (1) the unaudited financial data referred to in 4.b.(i) is
not stated on a basis substantially consistent with that of the audited financial statements included in the Offering Circular because such data does not reflect the application of the following generally accepted accounting principle: the recording
of the initial deferred tax impact associated with the change in status for federal income tax purposes and any subsequent income tax provisions; (2) at August 31, 2012, there was no increase in long-term debt or decrease in net current
assets (working capital), or member’s interest, as compared with amounts shown in the June 30, 2012 unaudited condensed consolidated balance sheet included in the Offering Circular; and (3) there were no decreases for the period from
July 1, 2012 to August 31, 2012, as compared with the corresponding period in the preceding year, in consolidated revenues or net income (loss). The results of our inquiries should be considered in light of the fact, as noted above, that
those Issuer officials stated that the financial data for July and August of both 2012 and 2011 was not prepared in accordance with generally accepted accounting principles as it does not reflect the application of the following generally accepted
accounting principle: the recording of the initial deferred tax impact associated with the change in status for federal income tax purposes and any subsequent income tax provisions. If the Company had recorded the initial deferred tax impact
associated with the change in status for federal income tax purposes to the July and August of both 2012 and 2011 financial data changes, increases or decreases in the balances or amounts referred to above might have been reported to you and those
changes, increases or decreases might have been material. 
  

	5.	Nothing came to our attention as a result of the foregoing procedures, however, that caused us to believe that: 

 

	 	a.	(i) Any material modifications should be made to the unaudited condensed consolidated financial statements described in 4.a.(i), included or incorporated by reference
in the Offering Circular, for them to be in conformity with generally accepted accounting principles. 

 (ii) The
unaudited condensed consolidated financial statements described in 4.a.(i) do not comply as to form in all material respects with the applicable sections of Regulation S-X. 

 

	6.	As mentioned in 4.b.(i), Issuer officials have advised us that no consolidated financial data as of any date or for any period subsequent to August 31, 2012 are
available; accordingly, the procedures carried out by us with respect to changes in financial statement items after August 31, 2012 have, of necessity, been even more limited than those with respect to the periods referred to in 4.b. We have
inquired of certain officials of the Issuer who have responsibility for financial and accounting matters as to whether (a) at October 31, 2012 there was any increase in long-term debt, or decrease in consolidated net current assets
(working capital) or member’s interest of the Issuer and consolidated subsidiaries as compared with amounts shown in the June 30, 2012 unaudited condensed consolidated balance sheet included in the Offering Circular; or (b) for the
period from July 1, 2012 to October 31, 2012, there were any decreases, as compared with the corresponding period in the preceding year, in consolidated revenues or net income (loss). 

Those officials referred to above stated that at October 31, 2012 they cannot comment on any such decreases in consolidated net
current assets (working capital), member’s interest, consolidated revenues or net income (loss) for the periods referred to above. 
 On the basis of these inquiries and our reading of the minutes as described in 4, nothing came to our attention that caused us to believe that there was any such increase in long-term debt, except in all
instances for increases that the Offering Circular discloses have occurred or may occur. 
  

	7.	 For purposes of this letter, we have also read the items identified by you on the attached copies of (a) the prospectus forming part of the
Offering Circular, (b) the Issuer’s quarterly report on Form 10-Q for the 

	 	
quarter ended March 31, 2012, (c) the Issuer’s quarterly report on Form 10-Q for the quarter ended June 30, 2012, (d) Northern Tier Energy LP’s quarterly report on
Form 10-Q for the quarter ended June 30, 2012 and (e) Northern Tier Energy LP’s and the Issuer’s Form 8-K dated June 30, 2012 and have performed the following procedures, which were applied as indicated with respect to the

reasons given for changes between periods. It should be noted that EBITDA, refinery gross product margin, merchandise margin, or retail fuel gross margin are not measures of operating performance or liquidity defined by generally accepted accounting
principles and may not be comparable to similarly titled measures presented by other companies. We make no comment about the definition, calculation or presentation of EBITDA, refinery gross product margin, merchandise margin or retail fuel gross
margin or their usefulness for any purposes. Additionally, we make no comment as to the appropriateness or manner of presentation of the definition of selected items impacting EBITDA, refinery gross product margin, merchandise margin or retail fuel
gross margin are, including “unusual,” “non-recurring,” or “incremental.”

appropriateness of the reasons given for changes between periods (2) the appropriateness or completeness of the Issuer or Northern Tier Energy LP’s classification of its market risk instruments into market risk exposure categories or as to its
determination of the expected maturity dates or amounts; and (3) we make no comment as to the appropriateness or completeness of the Issuer or Northern Tier Energy LP’s determination of the Regulation S-K requirements for quantitative and
qualitative disclosures about market risks or as to the reasonableness of the Issuer or Northern Tier Energy LP’s assumptions underlying such disclosures. It should be noted that EBITDA, refinery gross product margin, merchandise margin, or
retail fuel gross margin are not measures of operating performance or liquidity defined by generally accepted accounting principles and may not be comparable to similarly titled measures presented by other companies. We make no comment about the
definition, calculation or presentation of EBITDA, refinery gross product margin, merchandise margin or retail fuel gross margin or their usefulness for any purposes. Additionally, we make no comment as to the appropriateness or manner of
presentation of the definition of selected items impacting EBITDA, refinery gross product margin, merchandise margin or retail fuel gross margin are, including “unusual,” “non-recurring,” or
“incremental.”
		
	 C
	  	Compared to or recomputed the amount from a corresponding amount on a schedule prepared by the Issuer or Predecessor Company, as applicable, from their accounting records and found

found such amounts

			
		  	to be in agreement and (b) determined that the schedule was mathematically correct. However, we make no comment as to whether the sale of the Senior Debt or any other transaction(s)
contemplated in the Offering Circular will be consummated or the use of proceeds as described therein will actually occur. It should be noted that EBITDA, refinery gross product margin, merchandise margin or retail fuel gross margin are not measures
of operating performance or liquidity defined by generally accepted accounting principles and may not be comparable to similarly titled measures presented by other companies. We make no comment about the definition, calculation or presentation of
EBITDA, refinery gross product margin, merchandise margin or retail fuel gross margin or their usefulness for any purposes. Additionally, we make no comment as to the appropriateness or manner of presentation of the definition of selected items
impacting EBITDA, refinery gross product margin, merchandise margin or retail fuel gross margin are, including “unusual,” “non-recurring,” or “incremental.”

financial statements and found such amounts to be in agreement, after giving effect to rounding, if applicable. We (a) compared the amounts on the schedule to corresponding amounts appearing in either the Issuer or Predecessor Company’s
financial statements, as applicable, and found such amounts to be in agreement and (b) determined that the schedule was mathematically correct. However, we make no comment about the definition, calculation or presentation of average monthly run rate
or its usefulness for any purposes. Where applicable, we make no comment with respect to the appropriateness of the reasons given for changes between periods.
		
	E	  	Compared to or recomputed the amount from a corresponding amount in the audited financial statements or related notes to the audited financial statements of the Predecessor Company,

the historical amounts from a corresponding amount on the unaudited condensed consolidated financial statements of the Issuer included or incorporated by reference in the Offering Circular, as applicable, and found such amounts to be in agreement,
after giving effect to rounding; (2) recomputed the pro forma column by giving effect to the transactions related to the proposed sources of proceeds from the sale of Senior Debt to be offered by means of the Offering Circular, the repayment of the

consummated or the uses of proceeds as described therein will actually occur.

	8.	Our audit of the consolidated and combined financial statements for the periods referred to in the introductory paragraph of this letter comprised audit tests and
procedures deemed necessary for the purpose of expressing an opinion on such financial statements taken as a whole. For none of the periods referred to therein, or any other period, did we perform audit tests for the purpose of expressing an opinion
on individual balances of accounts or summaries of selected transactions such as those enumerated above, and, accordingly, we express no opinion thereon. 

  

	9.	It should be understood that we make no representations regarding questions of legal interpretation or regarding the sufficiency for your purposes of the procedures
enumerated in the second preceding paragraph; also, such procedures would not necessarily reveal any material misstatement of the amounts or percentages listed above. Further, we have addressed ourselves solely to the foregoing data as set forth in
the Offering Circular and make no representations regarding the adequacy of disclosure or regarding whether any material facts have been omitted. 

  

	10.	This letter is solely for the information of the addressees and to assist the Initial Purchasers in conducting and documenting their investigation of the affairs of the
