2.1    Purchase Requirement; Percentage of Demand; Monthly Maximum Supply
Availability.

(a)
From the Effective Date through and including *** (the “Primary Term”), subject
to Section 2.1(d), Supplier is obligated to sell and Halliburton is obligated to
buy *** tons of Northern White frac sand (the “First Phase Minimum Purchase
Requirement”).

(b)
From *** through and including *** (the “Secondary Term”), subject to Section
2.1(d), Supplier is obligated to sell and Halliburton is obligated to buy ***
tons of Northern White frac sand (the “Second Phase Minimum Purchase
Requirement”).

(c)
From *** through and including December 31, 2018 (the “Final Term”), subject to
Section 2.1(d), Supplier is obligated to sell and Halliburton is obligated to
buy *** tons of Northern White frac sand each year (the “Final Phase Minimum

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

Exhibit 10.5
Confidential Treatment Requested by Hi-Crush Partners LP

Second Phase Minimum Purchase Requirement and the Final Phase Minimum Purchase
Requirement shall be collectively, the “Minimum Purchase Requirement.”

(d)
(i)    During any Contract Year of the Final Term, if *** percent (***%) of the
Halliburton Aggregate Demand is less than the Final Phase Minimum Purchase
Requirement of *** tons for such Contract Year (such Contract Year, a “POD
Adjustment Year”), then the Final Phase Minimum Purchase Requirement shall be
automatically reduced for, and only for, such Contract Year to be an amount
equal to the greater of: (A) *** percent (***%) of the Halliburton Aggregate
Demand (subject to the maximum of *** tons) or (B) *** tons (the “Adjusted
Minimum Purchase Requirement”). For the avoidance of doubt, the Parties
acknowledge and agree that any Adjusted Minimum Purchase Requirement for a
Contract Year shall apply during such Contract Year that is deemed a POD
Adjustment Year.

(ii.)    All volumes of Northern White frac sand that are included in a Purchase
Order that is accepted by Supplier (including volumes cancelled by Supplier or
unfulfilled by Supplier) shall be applied to the Minimum Purchase Requirement
for such Contract Year that the Purchase Order was placed by Halliburton;
provided, however, that notwithstanding the foregoing or anything to the
contrary contained herein, Halliburton is obligated to purchase ***.

(iii)    As promptly as practicable, but not later than thirty (30) days after
the end of (A) any of the first three calendar quarters of each Contract Year
during the Final Term during which Halliburton purchased less than *** tons of
Northern White frac sand, Halliburton shall cause to be prepared and delivered
to Supplier an internally prepared statement identifying the aggregate number of
tons of raw frac sand purchased by Halliburton during such calendar quarter and
*** of such raw frac sand purchased during such calendar quarter (each, a
“Quarterly Statement”) and (B) the final calendar quarter of each Contract Year,
Halliburton shall cause to be prepared and delivered to Supplier an internally
prepared statement identifying the aggregate number of tons of Northern White
frac sand purchased by Halliburton during such Contract Year and *** of such
Northern White frac sand purchased during such Contract Year (each, an “Annual
Statement” and together with each Quarterly Statement, each a “Statement”).
(iv)    Supplier will have thirty (30) days after receipt from Halliburton of
each Statement to request a meeting with Halliburton representatives who
prepared such Statement to discuss and ask questions of the individuals who
prepared such Statement, which meeting shall occur not later than ten (10) days
following the date requested by Supplier. In addition, if Supplier, acting in
good faith and reasonably, does not agree with a Statement or any item contained
therein or the preparation thereof, Supplier will have the right to *** of
Halliburton in such a manner and detail as to permit verification of compliance
with Section 2.1(c) and this Section 2.1(d).
(e)
In the event that Supplier fails to supply to Halliburton the applicable Minimum
Purchase Requirement or, if applicable, the Adjusted Minimum Purchase
Requirement, during any Contract Year (a “Supply Shortfall”), Supplier shall
have *** (***) months after the end of such Contract Year to, as the sole and
exclusive remedy for such Supply Shortfall, either (i) tender the Supply
Shortfall, including by supplying Northern White frac sand from one or more
third parties in accordance with Section 2.11, (ii) hold Supply Shortfall in
Supplier inventory until such time that Halliburton requires the product, or
(iii) pay to Halliburton within *** (***) months of the end of the Contract Year
an amount equal to amount of the Supply Shortfall (expressed in tons) multiplied
by $***. It will be Supplier’s sole discretion as to which option is utilized.

(f)
(i)    The “Monthly Maximum Supply Availability” during the Term is set forth in
the table below. Supplier will not be obligated to fulfill orders that exceed
the Monthly Maximum Supply Availability for a specific calendar month.

(ii)    Supplier is not obligated to supply (A) during the Primary Term, more
than *** tons in any given calendar month of ***, *** or ***, (B) during the
Secondary Term, more than *** tons in any given calendar month of ***, *** or
*** and (C) during the Final Term, more than *** tons in any given calendar
month of ***, *** or ***. Notwithstanding the foregoing, Supplier will use
commercially reasonable efforts to fulfill orders that exceed the Monthly
Maximum Supply Availability and the monthly grade split maximums set forth in
this Section 2.1(f)(ii).
(iii)    Halliburton shall use commercially reasonable efforts to purchase on a
monthly and quarterly basis Northern White frac sand in *** (i.e. *** of
purchased volumes to be ***, *** of purchased volumes to be *** and *** of
purchased volumes to be ***) (the “Grade Split Target”); provided, however, that
Supplier acknowledges that rigid adherence to the Grade Split Target may
periodically not be possible due to shifting market dynamics and, subject to
this Section 2.1(f), Halliburton shall be permitted to purchase volumes of frac
sand and Supplier shall be obligated to sell volumes of frac sand that deviate
from the Grade Split Target in the event of shifting market dynamics.
Notwithstanding the foregoing, Halliburton acknowledges that Supplier’s ability
to supply Northern White frac sand to Halliburton in mesh size distributions
that vary materially from the Grade Split Target is constrained by Supplier’s
Northern White frac sand capabilities, physical plant configuration and
concurrently available reserve mix. In addition, Halliburton acknowledges that
Supplier is reserving Northern White frac sand of 20/40 Premium Frac Sand, 30/50
Premium Frac Sand and 40/70 Premium Frac Sand for Halliburton and that such
reserved Northern White frac sand would otherwise be sold by Supplier to other
third party consumers of such Northern White frac sand. In furtherance of the
foregoing, and to support Supplier’s status as a *** supplier of Northern White
frac sand to Halliburton, when placing Purchase Orders hereunder and works order
(or the equivalent thereof) with other third-party suppliers of Northern White
frac sand, Halliburton will give *** consideration to its obligation hereunder
to purchase Northern White frac sand in *** on a monthly and quarterly basis,
which shall include allocating its demand of the applicable mesh sizes of
Northern White frac sand to Supplier to ensure substantial compliance with the
Grade Split Target *** to allocating its demand of the applicable mesh sizes of
Northern White frac sand ***. For purposes of this Section 2.1(f)(iii),
“commercially reasonable efforts” shall be deemed to include the covenants made
by Halliburton in the immediately preceding sentence.
2.2    Price,Volume; Preferred Purchaser.

(a)
During the Term of this Agreement, F.O.B. mine pricing will be *** at (I)
$***/short ton of 20/40 Premium Frac Sand, (II) $***/short ton of 30/50 Premium
Frac Sand, and (III) $***/short ton of 40/70 Premium Frac Sand.

(b)
Supplier agrees that Halliburton shall be considered a preferred purchaser and,
accordingly, prices paid by Halliburton during the Term shall be no greater than
the lowest prices charged by Supplier for the same Northern White frac sand to
any current or future purchasers in the oilfield services industry during any
period covered by this Agreement. Notwithstanding the foregoing, this Section
shall not apply: (a) to contracts paid in advance; or (b) to contracts in place
between Supplier and other customers before August 1, 2011; or (c) to any Spot
Sales made by Supplier; or (d) to sales of Northern White frac sand from
facilities owned by Supplier at locations other than Supplier’s or its
affiliate’s facilities located in Augusta, Wisconsin, Whitehall Wisconsin and
Wyeville, Wisconsin. Notwithstanding anything to the contrary contained herein,
if Halliburton fails to purchase the Minimum Purchase Requirement during any
Contract Year (other than as a result of technical non-compliance as a result of
the timing of when a Purchase Order is placed by Halliburton and when the
Northern White frac sand is supplied by Supplier), then, upon determination that
Halliburton did not comply

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

Exhibit 10.5
Confidential Treatment Requested by Hi-Crush Partners LP

with the Minimum Purchase Requirement for such Contract Year, this Section
2.2(b) shall be deemed automatically deleted from the Agreement and Supplier
shall no longer be bound by the terms of this Section 2.2(b).

2.3
Halliburton Minimum Purchase Requirement. Halliburton shall be required to take
and, in accordance with Section 3.1, pay for (a) during the Primary Term, the
First Phase Minimum Purchase Requirement, (b) during the Secondary Term, the
Second Phase Minimum Purchase Requirement, and (c) during the Final Term, the
Final Phase Minimum Purchase Requirement or, if applicable, the Adjusted Minimum
Purchase Requirement; provided, however, that if, due solely to Force Majeure or
the unavailability of rail cars in the market, Halliburton is unable to take
delivery of Northern White frac sands as contemplated hereunder for a period of
time during a Contract Year, Halliburton shall not be deemed to be in breach of
this Agreement or be liable for Makewhole Payments as a result of such failure
so long as Halliburton is using best efforts to obtain rail cars and minimize
the period of time during which Halliburton is unable to take delivery of
Northern White frac sands.

2.4
Monthly Minimum Requirement. The Minimum Purchase Requirement shall be ordered
by Halliburton in installments of not less than *** tons of Northern White frac
sand per calendar month during the Primary Term, *** tons of Northern White frac
sand per calendar month during the Secondary Term and *** tons of Northern White
frac sand per calendar month during the Final Term (as applicable, the “Monthly
Minimum Requirement”). In the event that Halliburton fails to purchase the
Monthly Minimum Requirement from Supplier during any particular calendar month
in which Supplier was ready, willing and able to deliver the Monthly Minimum
Requirement, then the “Purchase Shortfall” shall be the amount by which the
Monthly Minimum Requirement exceeds the amount of Northern White frac sand
actually purchased by Halliburton during such calendar month.

2.5
Purchase Shortfall. Halliburton shall have *** (***) months after the month of
the Purchase Shortfall to purchase tonnage of Northern White frac sand in excess
of the applicable Monthly Minimum Requirement to make up for the Purchase
Shortfall. If Halliburton fails to purchase the full amount of the Purchase
Shortfall in such *** (***) month period, Halliburton shall be obligated to pay
to Supplier an amount equal to the amount of the Purchase Shortfall not
purchased by Halliburton in such *** (***) month period (expressed in tons)
multiplied by $*** (the “Makewhole Payment”). The Makewhole Payment shall be
paid within *** days of written demand by Supplier, by wire transfer of
immediately available funds to the account designated in writing by Supplier.
Halliburton reserves the right to resell goods purchased from Supplier if deemed
necessary by Halliburton in order to satisfy the Minimum Purchase Requirement
or, if applicable, the Adjusted Minimum Purchase Requirement. Supplier shall not
be obligated to deliver more than the Monthly Maximum Supply Availability on any
given calendar month. Notwithstanding the foregoing, in the event that a
Contract Year is deemed a POD Adjustment Year, then the Monthly Minimum
Requirement for such POD Adjustment Year shall be adjusted to be an amount equal
to one twelfth (1/12) of the Adjusted Minimum Purchase Requirement (the
“Adjusted Monthly Minimum Requirement”) and any Makewhole Payments actually paid
by Halliburton to Supplier that would otherwise not have been paid by
Halliburton to Supplier as a result of using the Adjusted Monthly Minimum
Requirement and not the Monthly Minimum Requirement to determine the Purchase
Shortfall shall be credited by Supplier to Halliburton for purchases hereunder.

2.6
Reconciliation. Within thirty (30) days after the close of the Contract Year,
Supplier shall provide a reconciliation of total volumes placed and/or purchased
by Halliburton and, upon final determination of the Halliburton Aggregate Demand
for such Contract Year, the total Purchase Shortfall amounts and total Purchase
Shortfall payments made by Halliburton as compared to the Minimum Purchase
Requirements. Notwithstanding any other provision in the Agreement to the
contrary, in the event of a discrepancy, the Parties agree that Halliburton
shall pay any Purchase Shortfall amounts due and owing; and, in the event that
Halliburton meets the Minimum Purchase Requirement after having paid Makewhole
Payments during the Contract Year, Supplier shall credit Halliburton for such
Makewhole Payments.

2.7
Forecast of Demand. Halliburton shall provide, on a quarterly basis, a
non-binding forecast on a monthly, quarterly and annual basis of its anticipated
purchase of Northern White frac sands (“Forecast Amount”).

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

Exhibit 10.5

Updates to the Forecast Amount will be made and communicated periodically
outside of the three-month rolling volume forecast as promptly as practicable
after Halliburton becomes aware of such changes. Supplier shall notify
Halliburton within ten (10) Business Days of receiving a forecast or update if
Supplier anticipates being unable to meet the anticipated purchase amounts.
Supplier shall not be obligated to deliver more than the Monthly Maximum Supply
Availability on any given calendar month.

2.8
Title and Risk Of Loss. Title and risk of loss or damage to Northern White frac
sands shall pass to Halliburton as defined by Incoterm, FCA (details listed in
table below), Incoterms 2010. Supplier is not responsible for unfilled orders
resulting from any shortage or lack of availability of rail cars for shipment of
orders except that Supplier and its affiliates must always meet the Monthly
Minimum Requirement volumes as specified in Section 2.4. Supplier warrants clear
title to the Northern White frac sands at the time title to the Northern White
frac sands passes to Halliburton, free from any and all liens or other
encumbrances. Supplier is responsible for properly loading and correct stowing
of the Northern White frac sand on the Halliburton nominated carrier, at its
expense, and will comply with any documentary instructions of Halliburton in the
shipment process. Notwithstanding anything to the contrary contained herein,

previously accepted Northern White frac sands upon such determination). Testing
of the applicable Northern White frac sand Sample shall be conducted by an
accredited third party laboratory or, due to timing considerations, by Supplier
at Supplier’s or its affiliate’s facility, as applicable, using ISO approved
testing equipment and following ISO and industry testing standards and protocol.
At the request of Halliburton, Supplier shall provide access to the facility for
the purpose of inspecting and observing the testing equipment, protocol and
results of a specific test. In the event that Halliburton timely rejects any
Northern White frac sands, Supplier shall replace such Northern White frac sands
at its sole cost. The time for fulfillment of the Minimum Purchase Requirement
shall be extended by the amount of time Supplier takes to replace the
non-conforming Northern White frac sand with conforming Northern White frac
sand.

Warranty and Claims. Except as expressly set forth in this Agreement, including,
without limitation, as expressly set forth in Section 5.1 above, no warranty,
express or implied, shall be applicable to the Northern White frac sand supplied
hereunder, including, without limitation, any warranty as to the quality of such
Northern White frac sand, any implied warranty of merchantability or suitability
or any implied warranty that any of such Northern White frac sand is fit for a
particular purpose, notwithstanding any course of dealing or industry practice
inconsistent with this Agreement. Should Halliburton choose to provide a
warranty to its customers beyond the warranty provided by Supplier, then
Halliburton shall bear the entire cost of such warranty. Should any Northern
White frac sand not comply with the warranties of Supplier expressly made in
this Agreement, then Supplier shall, as the sole and exclusive remedy of
Halliburton, promptly provide replacement Northern White frac sand to
Halliburton at Supplier’s Facility.

of excess liability insurance for such amount as may from time to time be agreed
between the Parties but in any event not be less than US$4,000,000 per
occurrence.

in confidence and shall not disclose such information to any third party or
otherwise use the Confidential Information except as stated herein or otherwise
agreed between the Parties.

not extend to or include Confidential Information exchanged between the Parties
that:

is obtained by the receiving Party from a source other than the disclosing Party
and where such source was free of any restrictions owed to the disclosing Party
on its use or disclosure;

(c)
was in the receiving Party’s possession prior to the receiving Party’s receipt
thereof from the disclosing Party, without any restriction owed to the
disclosing Party on its use or disclosure;

(d)
is required to be disclosed by operation of law, judicial or administrative
procedure, decree or order or by any regulation or law (including any rules and
regulations promulgated by the Securities and Exchange Commission); or

Non-Disclosure of Agreement. Except as otherwise provided under this Agreement
or as may be required by law or regulation (including any rules and regulations
promulgated by the Securities and Exchange Commission), neither Party, without

in the written opinion of a receiving Party’s counsel, the receiving Party shall
exercise reasonable efforts, with the cooperation of the disclosing Party, to
obtain an order or other reliable assurance that confidential treatment will be
accorded to the disclosed Confidential Information. Notwithstanding anything to
the contrary in this Agreement, Halliburton hereby agrees and acknowledges that
Supplier may disclose Supplier’s and its affiliates’ companywide aggregate
figures, including without limitation weighted average remaining contract length
and weighted average pricing, and such disclosure shall not be a violation of
the Agreement.

days, the Parties shall enter into discussions with a view to alleviating its

PRODUCT LIABILITY OR STRICT LIABILITY) OR WARRANTY.

9.3
Indemnification Procedure. In the event either Party learns of any claim,
liability, demand or cause of action relating to this Agreement or the

required by any of the terms of this Agreement, the indemnifying Party shall
have the right to control all litigation and shall defend the other and pay all
settlements, judgments, costs, and expenses (including without limitation court
costs and reasonable attorneys’ fees). Each Party, if requested, agrees to
cooperate with the other in any defense, and the indemnifying Party shall
reimburse the other for all reasonable expenses incurred in connection
therewith. The indemnified Party shall have the right to have counsel of its own

indemnified Party does not consent to a settlement which the indemnifying Party

to the amount for which the claim could have been settled provided such
settlement does not require the indemnified Party to forego any property rights
other than the amount of payment of the proposed settlement.

9.4
Compliance with Law. Subject to the limitations of this Agreement, it is agreed
that in the performance of this Agreement all matters shall be conducted in full
compliance with any and all applicable federal, state, provincial and local
laws, rules and regulations in the area(s) in which the matters are being
conducted. Any performance obligation arising under this Agreement is contingent
on the prior receipt of all necessary government authorizations. If either Party
is required to pay any fine or penalty or is subject to a claim from the other
Party’s failure to comply with applicable laws, rules or regulations, the Party
failing to comply shall defend, indemnify and hold harmless the other Party for
all damages, fees and/or fines for such failure to comply to the extent of the
indemnifying Party’s allocable share of the failure to comply.

and agents shall act in accordance with the principles described in the

and the Convention’s Commentaries (collectively the “OECD Principles”), and
shall comply with all applicable laws implementing the OECD Principles
(including the U.S. Foreign Corrupt Practices Act of 1977), as well as any
applicable local laws related to anti-corruption, anti-kickbacks, and anti-money

governmental official or employee (including employees of government-owned or
government-controlled corporations, agencies or bodies), (b) any official or
employee of a public international organization, (c) to any political party,
official of a political party or candidate, or (d) to any third party knowing,
believing, or suspecting that such third party will give the payment, or any
portion thereof, to any of the foregoing persons in order to obtain or retain
business, or for any other improper purpose. Any payments to governmental
officials or employees on behalf of Halliburton must be promptly reported to
Halliburton.

9.6
Code of Conduct/ Gifts, Entertainment and Travel. It is considered to be in
conflict with Halliburton’s interest for its employees or any member of their
immediate family to accept gifts, payments, extravagant entertainment, services,
or loans in any form from anyone soliciting business, or who may already have
established business relations with Halliburton. Gifts of nominal value and
entertainment, meals, and social invitations that are customary and proper under
the circumstances and that do not place the recipient under any obligation are
acceptable. Any gifts, payment of individual expenses, including, without
limitation, trips, or conveyances to Halliburton employees shall be disclosed in

Supplier shall maintain full and complete accounting records of activity
performed and expenditures incurred by Supplier in connection with this
Agreement in such a manner and detail as to permit verification of compliance
with the performance obligations, including, by way of illustration and not
limitation, pricing requirements, as well as the provisions of Sections 9.4
through 9.6 of this Agreement. Halliburton shall have the right to audit such
Supplier’s records for a period of two (2) years from the expiration or
termination of this Agreement. This provision shall survive expiration or

relevant records of Halliburton in such a manner and detail as to permit
verification of compliance with the performance obligations of Section
2.1(f)(iii) and as set forth in Section 2.1(d).

Notwithstanding anything to the contrary, neither Party shall be required to
take or refrain from taking any action prohibited or penalized under the laws of
the United States, including the U.S. antiboycott laws.
9.8    Economic Sanctions and Export Controls. Supplier agrees to fully comply
with all economic sanctions and export control laws and regulations, including
those regulations maintained by the U.S. Commerce Department’s Bureau of

provide, export, re-export, transfer, divert, loan, lease, consign or otherwise
dispose of any Halliburton equipment, Northern White frac sand, services,
software, source code, technical data or technology to or via any person, entity
or destination, or for any activity or end-use restricted by the laws or
regulations of the United States or any other applicable jurisdiction (including
nuclear, missile, chemical or biological weapons proliferation, military, or
money laundering activities) without first obtaining all required government
authorizations.

10.Nature of Agreement

10.1
Assignment. Either Party shall have the right to assign or transfer to any
Person any of its rights or obligations under this Agreement without the prior
written consent of the other Party, provided that the assigning Party shall
remain liable to the other Party under the terms of this Agreement
notwithstanding such assignment. This Agreement shall be binding on and inure to
the benefit of the Parties and their respective successors and permitted
assigns, including any successor upon a sale or change of control of a Party.
This Agreement is intended solely for the benefit of the Parties and their
respective successors and permitted assigns.

10.2
Relationship. Each of the Parties is an independent contractor with respect to
the other and is not an employee of the other Party or any of the other Party’s
Affiliates, and nothing in this Agreement is intended to constitute a
partnership or a master and servant relationship between the Parties. Each of
the Parties understands and agrees that this Agreement does not create an
exclusive dealings arrangement and that each of Halliburton and Supplier may
enter into similar arrangements with other companies with respect to similar or
the same Northern White frac sands. Nothing in this Agreement shall be construed
to create any duty to, or standard of care with reference to, or liability of a
Party to, any person not a Party to this Agreement. Nothing in this Agreement
shall be deemed to constitute any fiduciary or special relationship or duty
between the Parties and each Party may take actions hereunder that are for its
own self-interest without any duty or, subject to the express terms of this
Agreement, liability to the other Parties.

10.3
Entire Agreement; Amendment. This Agreement, including its appendices, exhibits
and schedules, constitutes the entire Agreement between the Parties with respect
to the subject matter hereof and supersedes any existing agreements between them
whether oral or written. The terms of this Agreement shall only be amended,
modified or supplemented as set forth herein or in a writing signed by or on
behalf of both or the Parties. In case of a conflict between this Agreement and
a purchase order (Purchase Order) or purchase order confirmation contemplated
hereunder, the terms of this Agreement shall govern. Acceptance of a Purchase
Order or purchase order confirmation is insufficient to amend this Agreement
unless a separate writing is duly executed by all the Parties specifically
amending this Agreement.

illegal or incapable of being enforced by any rule of law or public policy, all
other conditions and provisions of this Agreement shall nevertheless remain in
full force and effect so long as the economic and legal substance of the
transactions contemplated hereby are not affected in any manner materially
adverse to any Party. Upon the determination that any term or other provision is
invalid, illegal or incapable of being enforced, the Parties shall negotiate in
good faith to modify this Agreement so as to effect the original intent of the
Parties as closely as possible in an acceptable manner to the end that
transactions contemplated hereby are fulfilled to the extent possible. In the
event any such provision, clause, sentence or part of this Agreement cannot be
modified to comply with the law, then said provision, clause, sentence or
portion of the Agreement shall be deemed to be deleted from the Agreement and
the remaining terms and conditions shall remain in full force and effect.

It is the intent of the Parties to exclude the application of the United Nations
Convention on Contracts for the International Sale of Goods (1980). Nothing
herein shall prohibit a Party from availing itself of a court of competent
jurisdiction for the purpose of injunctive relief. The Parties acknowledge and
agree that the Parties may have available to them laws or remedies available
under applicable local legislation; it is the intent of the Parties to have the
terms of this Agreement apply in every instance, including, without limitation,
the choice of law provisions.

14.

Halliburton and Supplier with respect to its subject matter. All prior
negotiations and dealings regarding the subject matter hereof are superseded by
and merged into this Agreement. Specifically, Supplier and Halliburton
acknowledge that this Agreement amends and restates in their entirety the Prior
Supply Agreements and that the Prior Supply Agreements have no further legal
