 (d) Notwithstanding any other provision of this Agreement or any other Loan Document, except as otherwise provided in Section 2.1(b) above with respect to the conversion of Swing-Line Advances to Revolving
Advances, neither Agent nor any Lender shall have any obligation to: (1) make a Revolving Advance or a Swing-Line Advance to Borrowers (or reimburse Agent for a Revolving Advance or a Swing-Line Advance made to Borrowers) after the Maturity
Date (Revolving), (2) issue (or participate in the issuance of) a Letter of Credit which expires later than five days prior to the Maturity Date (Revolving) or later than two years after its date of issuance; provided that the foregoing shall
not be deemed to limit the issuance of Letters of Credit that are automatically renewable on an annual or other periodic basis unless the beneficiary is notified to the contrary, (3) issue (or participate in the issuance of) a LIBOR Tranche
with respect to any one or more Revolving Advances as to which the LIBOR Interest Period does not expire on or before the Maturity Date (Revolving), (4) issue (or participate in the issuance of) a LIBOR Tranche with respect to any one or more

integral multiple of $100,000, except for any Revolving Advance in an amount equal to the entire remaining availability under the Revolving Loan, (6) issue (or participate in the issuance of) a LIBOR Tranche if the aggregate amount of the LIBOR
Tranche

is less than $500,000 or is not an integral multiple of $100,000, (7) issue (or participate in the issuance of) a Letter of Credit if, after such Letter
of Credit is issued, the face amounts of all Letters of Credit outstanding under this Agreement would exceed $10,000,000, (8) make (or reimburse Agent for) a Revolving Advance or a Swing-Line Advance or issue (or participate in the issuance of)
a Letter of Credit if, after such Revolving Advance or Swing-Line Advance is made or such Letter of Credit is issued, the aggregate principal amounts of all Revolving Advances outstanding hereunder plus the aggregate principal amounts of all
Swing-Line Advances outstanding hereunder plus the face amounts of all Letters of Credit outstanding hereunder would exceed the Aggregate Lenders’ Commitment (Revolving), (9) with respect to a Lender, reimburse Agent for a Revolving
Advance or participate in the issuance of a Letter of Credit if, after such Revolving Advance is made or such Letter of Credit is issued, such Lender’s Percentage Share (Revolving) of the aggregate amount of all Revolving Advances outstanding
hereunder plus such Lender’s Percentage Share (Revolving) of the face amounts of all Letters of Credit outstanding hereunder would exceed such Lender’s Commitment (Revolving), or (10) with respect to Agent and the Swing-Line Lender,
make (or reimburse Agent for) a Swing-Line Advance if, after such Swing-Line Advance is made, the aggregate amount of all then-outstanding Swing-Line Advances shall exceed $15,000,000. 
 (e) Within the limitation of the Aggregate Lenders’ Commitment (Revolving) and subject to the other terms and provisions hereof, Borrowers may
borrow, repay and reborrow in accordance with the terms of this Section 2.1. The Revolving Advances, Swing-Line Advances and Letters of Credit described in this Section 2.1 shall be herein collectively referred to as the “Revolving

to the other terms and conditions of this Agreement, each Lender agrees to make (or reimburse Agent for) its Percentage Share (Term) of an amortizing term loan in the amount of $50,000,000 to be made to Borrowers on the same date as the Initial
Advance. 
 (b) Notwithstanding any other provision of this Agreement or any other Loan Document, neither Agent nor any Lender shall have any
obligation to: (1) make any advance on the Term Loan to Borrowers (or reimburse Agent for any advance on the Term Loan to Borrowers) other than the advance described in Section 2.2(a) above, (2) issue (or participate in the issuance
of) a LIBOR Tranche with respect to any portion of the Term Loan as to which the LIBOR Interest Period does not expire on or before the Maturity Date (Term), (3) issue (or participate in the issuance of) a LIBOR Tranche with respect to any

 Section 2.3. The Notes; Interest. (a) Borrowers’ obligation to repay the following, with
interest thereon, shall be evidenced by the Note made payable to the order of each Lender: (1) any and all Revolving Advances, which shall be payable to each Lender in accordance with such Lender’s Percentage Share (Revolving),
(2) any and all Swing-Line Advances, which shall be payable to the Swing-Line Lender, and (3) the Term Loan, which shall be payable to each Lender in accordance with such Lender’s Percentage Share (Term). The face amount of any Note
made payable to a Lender may at any time or from time to time exceed the amount of such Lender’s Commitment; provided that no such face amount shall be deemed to commit or require the affected Lender to lend any amount greater than such
Lender’s Commitment. 
 (b) At any time and from time to time hereafter, if Borrowers desire to include in a LIBOR Tranche all or any
portion of the Revolving Loan (other than any outstanding Swing-Line Advances or Letters of Credit) that will not already be included in a LIBOR Tranche as of the beginning of the requested LIBOR Interest Period or all or any portion of the Term
Loan that will not already be included in a LIBOR Tranche as of the beginning of the requested LIBOR Interest Period, Borrowers shall deliver an Interest Rate Election to Agent not later than 11:00 a.m., Seattle, Washington time three Business Days
prior to the first day of the requested LIBOR Interest Period, specifying the dollar amount Borrowers desire to have included in the LIBOR Tranche, the first day of the LIBOR Interest Period, the duration of the LIBOR Interest Period and whether
such LIBOR Tranche relates to the Revolving Loan or the Term Loan. As soon as reasonably possible after LIBOR can be determined for the requested LIBOR Interest Period, Agent shall provide to Borrowers a quote of LIBOR for the dollar amount and time
period requested by Borrowers. If the inclusion of the requested portion of the Revolving Loan or the Term Loan in the requested LIBOR Tranche is in conformity with all of the terms and provisions of this Agreement, the LIBOR Tranche shall become
effective for the requested dollar amount and the applicable LIBOR Interest Period based upon the rate quoted by Agent. Any portion of the Revolving Loan (other than outstanding Swing-Line Advances or Letters of Credit) or the Term Loan which is not
included in a LIBOR Tranche shall be included in the Base Rate Portion. 
 (c) (1) Except as otherwise provided in (4) below, interest
on the unpaid principal balance of each LIBOR Tranche shall accrue on a daily basis at an annual rate equal to: (A) LIBOR, as fixed with respect to such LIBOR Tranche, plus (B) the applicable LIBOR Spread in effect for such day.
(2) Except as otherwise provided in (4) below, the unpaid principal balance of the Base Rate Portion shall accrue on a daily basis at an annual rate equal to the Base Rate (such interest rate to be adjusted each time that the Base Rate
changes) plus the applicable Base Rate Spread in effect for such day. (3) Except as otherwise provided in (4) below, interest on the unpaid principal balance of any and all outstanding Swing-Line Advances shall accrue on a daily basis at
an annual rate equal to the applicable Swing-Line Interest Rate for such day. (4) From and after the occurrence, and during the continuance, of any Event of Default hereunder (including without limitation any failure by Borrowers to pay the
entire outstanding principal balance of the Revolving Loan, together with all accrued interest, fees and other amounts payable in connection therewith on or before the Maturity Date (Revolving) or any failure by Borrowers to pay the entire
outstanding principal balance of the Term Loan, together with all accrued interest, fees and other amounts payable in connection therewith on or before the Maturity Date (Term)), interest on any LIBOR Tranche, on the Base Rate Portion and 

  

 20 

 
on any outstanding Swing-Line Advances shall accrue, from the date of occurrence of the Event of Default until the date the Event of Default is cured, at the
annual rate otherwise applicable to such LIBOR Tranche, Base Rate Portion or Swing-Line Advance plus two percentage points per annum. 
 (d)
Interest accrued on the Base Rate Portion and on any and all outstanding Swing-Line Advances shall be due and payable on each Monthly Payment Date. Interest accrued on each LIBOR Tranche shall be due and payable on the last day of the LIBOR Interest
Period for such LIBOR Tranche (and, in the case of any LIBOR Tranche having a LIBOR Interest Period in excess of three months, on the three-month anniversary of the first day of such LIBOR Interest Period). Any then-outstanding interest on the
Revolving Loan shall be due and payable not later than the Maturity Date (Revolving). Any then-outstanding interest on the Term Loan shall be due and payable not later than the Maturity Date (Term). 
 Section 2.4. Mandatory Principal Payments. (a)(1) On or before each Quarterly Payment Date prior to the Maturity Date (Term), Borrowers shall
make a principal payment to Agent, on behalf of Lenders in proportion to their respective Percentage Shares (Term), in the amount of $1,250,000 (the “Amortization Amount (Term)”), subject to any applicable adjustment pursuant to
Section 2.4(a)(2) below. (2) As to the first payment, if any, made by any Borrower within six months after the date of this Agreement, of an amount in excess of $10,000,000 that constitutes the payment of a Mandatory Prepayment Amount
determined under clause (b) of the definition of such term and/or a voluntary prepayment under Section 2.5 below, then the Amortization Amount (Term) shall be reduced to the amount that would be necessary to amortize the outstanding
principal balance of the Term Loan with level quarterly principal payments on each Quarterly Payment Date through and including the Quarterly Payment Date for the calendar quarter ending September 30, 2017. 
 (b) Not later than three Business Days after the receipt by any Borrower of any amount included in Mandatory Prepayment Amounts, Borrowers shall make a
principal payment to Agent, on behalf of Lenders in proportion to their respective Percentage Shares (Term), in the amount of the Mandatory Prepayment Amounts so received. Any such amount received by Agent shall be applied first against that portion
of the Term Loan that would otherwise have been due and payable on the Maturity Date (Term) until such portion of the Term Loan has been repaid in full and next against quarterly principal payments required under Section 2.4(a) above in the
inverse order of approaching maturities. 
 (c) The outstanding principal balance of the Revolving Loan, together with all unpaid fees and
expenses relating thereto as provided herein, shall be due and payable not later than the Maturity Date (Revolving). The outstanding principal balance of the Term Loan, together with all unpaid fees and expenses relating thereto as provided herein,
shall be due and payable not later than the Maturity Date (Term). Any payment made by any Borrower for application to the repayment of the Loans after the occurrence and during the continuance of an Event of Default shall be applied ratably between
the Revolving Loan and the Term Loan in accordance with the respective amounts due and payable on each. 
  

 21 

 Section 2.5. Voluntary Prepayments. Borrowers shall have the right to prepay any or all
Advances or all or any portion of the outstanding balance of the Term Loan at any time, in whole or in part, without penalty or premium (except as otherwise described in Section 3.5 below); provided that, as to any such prepayment that will
result in a prepayment, in whole or in part, of a LIBOR Tranche prior to the last day of the relevant LIBOR Interest Period: (a) Borrowers shall give Agent at least three Business Days’ prior notice thereof, and (b) such prepayment
shall be in an amount such that the unpaid principal balance of the prepaid LIBOR Tranche shall continue to be an integral multiple of $100,000 not less than $500,000. Borrowers shall designate whether any such prepayment is to be applied to the
repayment of outstanding Revolving Advances, outstanding Swing-Line Advances or the unpaid principal balance of the Term Loan. Any prepayment received by Agent that is to be applied to the repayment of the unpaid principal balance of the Term Loan
shall be applied first against that portion of the Term Loan that would otherwise have been due and payable on the Maturity Date (Term) until such portion of the Term Loan has been repaid in full and next against quarterly principal payments
required under Section 2.4(a) above in the inverse order of approaching maturities. 
 Section 2.6. Termination of Agreement;
Reduction of Aggregate Lenders’ Commitment (Revolving). (a) Borrowers shall have the right at any time and from time to time, upon not less than three Business Days’ prior written notice to Agent, to terminate this Agreement. No such
termination of this Agreement shall be effective until Borrowers have paid in full any and all amounts payable hereunder, including principal, interest, fees, expenses and other amounts and have caused all outstanding Letters of Credit to be
terminated and released. Any prepayment made in connection with a termination of this Agreement shall be without penalty or premium (except as otherwise described in Section 3.5 below). 
 (b) Borrowers shall have the right at any time and from time to time, upon not less than three Business Days’ prior written notice to Agent, to
elect to reduce the Aggregate Lenders’ Commitment (Revolving) to an amount less than otherwise specified in this Agreement, which amount shall be specified in such notice and shall be an integral multiple of $1,000,000. Any such election shall
be permanent and irrevocable and shall be accompanied by any principal payment required to reduce the outstanding balance of the Revolving Loan to an amount not greater than the reduced Aggregate Lenders’ Commitment (Revolving) so elected. Any
such reduction shall result in the pro rata reduction of the Commitments (Revolving) of all Lenders participating in the Revolving Loan. 
 Section 2.7. Payments to Agent. Borrowers shall pay to Agent, on behalf of Lenders, each payment that Borrowers owe under the Loan Documents not later than 10:00 a.m., Seattle, Washington time, on the due date, in lawful money
of the United States of America and in immediately available funds. Any payment received after such time will be deemed to have been made on the next following Business Day. Except as otherwise provided in this Agreement as to LIBOR Tranches, should
any such payment become due and payable on a day other than a Business Day, the maturity of such payment shall be extended to the next succeeding Business Day, and, in the case of a payment of principal or past due interest, interest shall accrue
and be due and payable thereon for the period of such extension. Each payment under a Loan Document shall be due and payable at the place provided therein or, if no specific place of payment is provided, shall be due and payable at the place of
payment provided in the Notes. 
  

 22 

 With respect to any regularly scheduled payment of principal, interest, fees or other amounts due and payable hereunder,
Borrowers hereby authorize Agent to: (a) debit any deposit account of any Borrower with USB, or (b) make a Swing-Line Advance or a Revolving Advance, in the amount of the payment then due. If there are insufficient funds in such deposit
accounts to pay in full the amounts then due, such debits will be reversed (in whole or in part, at Agent’s sole discretion) and such amount not debited shall be deemed to be unpaid. 
 Section 2.8. Use of Proceeds. In no event shall any of the proceeds of the Revolving Loan or the Term Loan be used directly or indirectly for
the purpose, whether immediate, incidental or ultimate, of purchasing, acquiring or carrying any “margin stock” (as such term is defined in Regulation U promulgated by the Board of Governors of the Federal Reserve System) or to extend
credit to others directly or indirectly for the purpose of purchasing or carrying any such margin stock. Borrowers represent and warrant to Agent and Lenders that no Borrower is engaged principally, or as one of its important activities, in the
business of extending credit to others for the purpose of purchasing or carrying such margin stock. Borrowers will use the proceeds of the Loans: (a) initially, for the purposes of refinancing any and all amounts payable under or in connection
with the Existing USB Loan, repaying in full the Long Canyon Note and paying in full any and all fees and expenses payable to Agent or any Lender in connection with the funding of the Loans, and (b) thereafter, for general working capital
purposes, capital expenditures relating to the maintenance or expansion of existing potash, magnesium chloride or salt mining operations, financing permitted Distributions to members, making permitted acquisitions of other assets or operations, the
issuance of Letters of Credit in connection with Borrowers’ business activities and other lawful purposes in connection with Borrowers’ business activities and, to the extent permitted under the terms of this Agreement, making
contributions, loans or advances to any Subsidiary of any Borrower for any of the foregoing purposes. 
 ARTICLE III 
 Security; Fees; Letters of Credit; LIBOR Provisions 
 Section 3.1. The Security. The Obligations will be secured on a pari passu basis by the existing Security Documents heretofore executed and delivered in connection with the Existing USB Credit
Agreement, the Security Documents executed and delivered contemporaneously herewith and any additional Security Documents hereafter delivered by any Obligated Person and accepted by Agent, on behalf of Lenders; provided that, promptly after a
written request from Borrowers to Agent, contemporaneously with the incurrence of any Permitted Third-Party Solution Mining Project Debt, Agent and Lenders hereby agree to partially release the Security Documents insofar as they cover any Permitted
Solution Mining Project Security. 
 Section 3.2. Perfection and Protection of Security Interests and Liens. Borrowers will from
time to time deliver (or cause to be delivered) to Agent, on behalf of Lenders, any amendments, financing statements, continuation statements, extension agreements and other documents, properly completed and executed (and acknowledged when required)
by Borrowers or any other Obligated Person, in form and substance reasonably satisfactory to Agent, which Agent may request for the purpose of perfecting, confirming or protecting Lenders’ Liens and other rights in the Collateral. 

 

 23 

 Section 3.3. Bank Accounts and Offset. To secure the repayment of the Obligations, each
Borrower hereby grants to Agent, on behalf of Lenders, a security interest, a lien and a right of offset, each of which shall be upon and against: (a) any and all moneys, securities or other property (and the proceeds therefrom) of such
Borrower now or hereafter held or received by or in transit to any Lender from or for the account of such Borrower, whether for safekeeping, custody, pledge, transmission, collection or otherwise, (b) any and all deposits (general or special,
time or demand, provisional or final) of such Borrower with any Lender, and (c) any other credits and claims of such Borrower at any time existing against any Lender, including without limitation claims under certificates of deposit; provided
that the foregoing shall not apply to any amounts held by any Lender in the capacity of an escrow agent. Upon the occurrence and during the continuance of any Event of Default, each Lender is hereby authorized to foreclose upon, offset, appropriate
and apply, at any time and from time to time, without notice to Borrowers, any and all items hereinabove referred to against the Obligations (whether or not such Obligations are then due and payable). 
 Section 3.4. Fees. (a) Borrowers shall pay to Agent, for the account of each Lender, for the time period commencing on and including the
date of the Initial Advance to but excluding the Maturity Date (Revolving), on the last day of each calendar quarter prior to the Maturity Date (Revolving) (or, if such last day is not a Business Day, on the next succeeding Business Day), and on the
Maturity Date (Revolving) (or, if the Maturity Date (Revolving) is not a Business Day, on the next succeeding Business Day), a nonrefundable commitment fee in an amount equal to the following, computed on a daily basis: (1) the Commitment Fee
Rate per annum as of each day in such calendar quarter or other time period, times (2) the excess, if any, of: (A) such Lender’s Commitment (Revolving), over (B) the sum of: (i) such Lender’s Percentage Share
(Revolving) of the aggregate outstanding principal balance of all Revolving Advances, plus (ii) such Lender’s Percentage Share (Revolving) of the face amounts of all outstanding Letters of Credit, plus (iii) in the case of the
Swing-Line Lender only, the aggregate principal balance of any and all Swing-Line Advances outstanding as of the end of such day, times (3) the length of such calendar quarter or other time period, expressed as a fraction of a year, based on
the actual number of days and a 360-day year. 
 (b) Borrowers shall pay to Agent, for the account of Lenders, a Letter of Credit fee in an
amount calculated on a daily basis for each calendar quarter or portion thereof from the date of the Initial Advance through the date that all Letters of Credit have been terminated, in an amount equal to: (1) the applicable LIBOR Spread per
annum in effect as of such day, times (2) the sum of the face amounts of all Letters of Credit outstanding for all or any part of such day, times (3) the length of such calendar quarter or other time period, expressed as a fraction of a
year; provided that, in addition to the fee described above, if there shall be more than one Lender hereunder as of the date of issuance (or the date of renewal) of any Letter of Credit, Borrowers shall also pay to Agent, for the benefit of Agent
and not of Lenders, a fronting fee in an amount equal to 0.125 percentage points per annum times the face amount of such Letter of Credit. In addition, at the time of issuance, amendment or drawing of each Letter of Credit, Borrowers shall pay to
Agent, for the account of Agent and not of Lenders, Agent’s customary fees for administrative issuance, amendment or drawing of such Letter of Credit; provided that no such individual administrative issuance, amendment or drawing fee shall
exceed $500. The Letter of Credit fee and, the fronting fee described above shall be calculated on the 

  

 24 

 
undrawn face amount of each Letter of Credit outstanding on each day at the above-described rates and will be due and payable in arrears on the last day of
each calendar quarter (or, if such last day is not a Business Day, on the next succeeding Business Day) and on the Maturity Date (Revolving) (or, if the Maturity Date (Revolving) is not a Business Day, on the next succeeding Business Day).

 (c) Borrowers shall pay to Agent such fees as are described in the Fee Letter, which fees shall be for the account of Agent, except to the
extent otherwise provided herein or as otherwise agreed between Agent and any Lender. 
 Section 3.5. Special LIBOR Provisions.
(a) If any Lender shall reasonably determine (that the introduction of or any change in or in the interpretation of any law makes it unlawful, or any central bank or other governmental authority having jurisdiction asserts that it is unlawful,
for such Lender to fund, continue or maintain any LIBOR Tranche, the obligation of such Lender to fund, continue or maintain any such LIBOR Tranche shall, upon such determination, forthwith be suspended until such Lender shall notify Borrowers that
the circumstances causing such suspension no longer exist, and all LIBOR Tranches shall automatically be converted into the Base Rate Portion at the end of the then-current LIBOR Interest Periods with respect thereto or sooner, if required by such
law or assertion. 
 (b) If Agent shall reasonably determine that: 
 (1) U.S. Dollar deposits in the relevant amount and for the relevant LIBOR Interest Period are not available; or 
 (2) By reason of circumstances affecting Agent’s relevant market, adequate means do not exist for ascertaining the interest rate applicable
hereunder to LIBOR Tranches; 
 then, upon notice from Agent to Borrowers, the obligation of Lenders to include any portion of the Loans in a LIBOR Tranche
shall forthwith be suspended until Agent shall notify Borrowers that the circumstances causing such suspension no longer exist. 
 (c)
Borrowers agree to reimburse any Lender for any increase in the cost (other than Taxes, which are covered by Section 3.7), to such Lender of, or any reduction in the amount of any sum receivable by such Lender in respect of, funding, continuing
or maintaining (or of its obligation to fund, continue or maintain) any LIBOR Tranche as a result of any change in, or in the interpretation of, any law, rule, regulation or other governmental enactment or policy, by any central bank or other
governmental authority. Such Lender shall promptly notify Borrowers in writing of the occurrence of any such event, such notice to state, in reasonable detail, the reasons therefor and the additional amount required to compensate fully such Lender
for such increased cost or reduced amount. Such additional amount shall be due and payable by Borrowers to such Lender within fifteen days of Borrowers’ receipt of such notice, and such notice shall be prima facie evidence of such increase in
cost or reduction of amount receivable. 
 (d) In the event any Lender shall incur any loss or expense (including any loss or expense
incurred by reason of the liquidation or reemployment of deposits or other funds 

  

 25 

 
acquired by such Lender to fund, continue or maintain any portion of the principal amount of any LIBOR Tranche) as a result of: 
 (1) Any conversion, repayment or prepayment (whether voluntary or mandatory) of the principal amount of any LIBOR Tranche on a date other than the
scheduled last day of the LIBOR Interest Period applicable thereto; or 
 (2) Any requested LIBOR Tranche not being funded as a LIBOR
Tranche in accordance with the provisions of this Agreement or the Interest Rate Election therefor for reasons beyond the control of such Lender or Agent; 
 then, upon the written notice of such Lender to Borrowers, Borrowers shall, within fifteen days of receipt thereof, pay such Lender such amount as will (in the reasonable determination of such Lender) reimburse such Lender for such loss or
expense. Such written notice (which shall include calculations in reasonable detail in accordance with Exhibit E attached hereto and made a part hereof) shall constitute prima facie evidence of such loss or expense. 
 Section 3.6. Increased Capital Costs. If any change in, or the introduction, adoption, effectiveness, interpretation, reinterpretation or
phase-in of, any law or regulation, directive, guideline, decision or request (whether or not having the force of law) of any court, central bank, regulator or other governmental authority affects or would affect the amount of capital required or
expected to be maintained by any Lender or any Person controlling any Lender, and such Lender reasonably determines that the rate of return on its or such controlling Person’s capital as a consequence of the Loans is reduced to a level below
that which such Lender or such controlling Person could have achieved but for the occurrence of any such circumstance, then, in any such case upon notice from time to time by such Lender to Borrowers, Borrowers hereby agree to pay to such Lender,
within fifteen days of the effective date of such notice, such additional amount (as may be reasonably determined by such Lender) sufficient to compensate such Lender or such controlling Person for such reduction in rate of return. A statement to
Borrowers by any Lender as to any such additional amount or amounts (including calculations thereof in reasonable detail) shall be prima facie evidence of such amount or amounts. 
 Section 3.7. Taxes. (a) Except as otherwise required by applicable law, all payments by Borrowers of principal of, and interest on, either of
the Loans and all other amounts payable hereunder shall be made free and clear of and without deduction for any present or future income, excise, stamp or franchise taxes’ and other taxes, fees, duties, withholdings or other charges of any
nature whatsoever imposed by any taxing authority, but excluding franchise taxes and taxes imposed on or measured by any Lender’s net income or receipts (such non-excluded items being called “Taxes”). Subject to Section 3.7(b)
below, in the event that any withholding or deduction from any payment to be made by Borrowers hereunder is required in respect of any Taxes pursuant to any applicable law, rule or regulation, Borrowers will: (1) pay directly to the relevant
authority the full amount required to be so withheld or deducted; (2) promptly forward to such Lender an official receipt or other documentation satisfactory to such Lender evidencing such payment to such authority; and (3) pay such Lender
such additional amount or amounts as may be necessary to ensure that the net amount actually received by such Lender will equal the full amount such Lender would have received had no such withholding or deduction been 
  

 26 

 
required. Moreover, subject to Section 3.7(b) below, if any Taxes are directly asserted against any Lender with respect to any payment received by such
Lender hereunder, such Lender may pay such Taxes and Borrowers will promptly pay such additional amounts (including any penalties, interest or expenses) as may be necessary in order that the net amount -received by such Lender after the payment of
such Taxes (including any Taxes on such additional amount) shall equal the amount such Lender would have received had not such Taxes been asserted. If Borrowers fail to pay any Taxes when due to the appropriate taxing authority or fail to remit to
any Lender the required receipts or other required documentary evidence, then, subject to Section 3.7(b) below, Borrowers shall indemnify, save and hold harmless such Lender from and against any incremental Taxes, interest or penalties that may
become payable by such Lender as a result of any such failure. 
 (b) Each Lender that is not incorporated under the laws of the United
States of America or a state thereof (each a “Non-U.S. Lender”) agrees that it will, not less than ten Business Days after the date that it becomes a Lender hereunder: (1) deliver to Borrowers and to Agent two duly completed copies of
United States Internal Revenue Service Form W-8BEN or W-8ECI, certifying in either case that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, and
(2) deliver to Borrowers and to Agent a United States Internal Revenue Form W-8 or W-9, as the case may be, and certify that it is entitled to an exemption from United States backup withholding tax. Each Non-U.S. Lender further undertakes to
deliver to Borrowers and to Agent (x) renewals or additional copies of such form (or any successor form) on or before the date that such form expires or becomes obsolete, and (y) after the occurrence of any event requiring a change in the
most recent forms so delivered by it, such additional forms or amendments thereto as may be reasonably requested by Borrowers or Agent. All forms or amendments described in the preceding sentence shall certify that such Lender is entitled to receive
payments under this Agreement without deduction or withholding of any United States federal income taxes, unless an event (including any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise
be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form or amendment with respect to it and such Lender advises Borrowers and Agent that it is not capable of
receiving payments without any deduction or withholding of United States federal income tax. 
 (c) For any period during which a Non-U.S.
Lender has failed to provide Borrowers with an appropriate form pursuant to Section 3.7(b) above (unless such failure is due to a change in treaty, law or regulation, or any change in the interpretation or administration thereof by any
governmental authority, occurring subsequent to the date on which a form originally was required to be provided), such Non-U.S. Lender shall not be entitled to indemnification under this Section 3.7 with respect to Taxes imposed by the United
States; provided that, should a Non-U.S. Lender which is otherwise exempt from or subject to a reduced rate of withholding tax become subject to Taxes because of its failure to deliver a form required under Section 3.7(b) above, Borrowers shall
take such steps as such Non-U.S. Lender shall reasonably request to assist such Non-U.S. Lender to recover such Taxes. 
 (d) Any Lender that
is entitled to an exemption from or reduction of withholding tax with respect to payments under this Agreement or any Note pursuant to the law of any 

  

 27 

 
relevant jurisdiction or any treaty shall deliver to Borrowers (with a copy to Agent), at the time or times prescribed by applicable law, such properly
completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate. 
 (e) If the U.S. Internal Revenue Service or any other governmental authority of the United States or any other country or any political subdivision thereof asserts a claim that Agent did not properly withhold tax from amounts paid to or for
the account of any Lender (because the appropriate form was not delivered or properly completed, because such Lender failed to notify Agent of a change in circumstances which rendered its exemption from withholding ineffective or for any other
reason), such Lender shall indemnify Agent fully for all amounts paid, directly or indirectly, by Agent as tax, withholding therefor or otherwise, including penalties and interest, and including taxes imposed by any jurisdiction on amounts payable
to Agent under this Section 3.7(e), together with all costs and expenses related thereto (including expenses and fees and/or time charges of the attorneys for Agent, who may be employees of Agent). The obligations of Lenders under this
Section 3.7(e) shall survive the payment of the Obligations and termination of this Agreement.

under the terms of each indenture, mortgage, deed of trust, security agreement, lease, franchise, agreement, contract or other instrument or obligation to which it is a party or by which it or any of its properties is bound in a manner that will not

not have a Material Adverse Effect.

year, and (3) notify Agent immediately of any fact, including, but not limited to, any 

  

 40 

 
reportable event (as described in Section 4043 of ERISA or the regulations promulgated thereunder) arising in connection with any and all ERISA Plans,
which might constitute grounds for termination thereof by the PBGC or for the appointment by the appropriate United States District Court of a trustee to administer such ERISA Plans, together with a statement, if requested by Lenders, as to the
reason therefor and the action, if any, proposed to be taken with respect thereto.

its property free of any hazardous substance, hazardous waste or solid waste (other than hazardous substances, hazardous wastes and solid wastes normally used or generated in the ordinary course of operation of Borrowers’ facilities and that
are properly stored, maintained and disposed of in accordance with Environmental Laws) and to remove the same (or if removal is prohibited by law, to take, at its sole expense, whatever actions are required by law) in accordance with Environmental
Laws. Upon Agent’s reasonable request, at any time and from time to time during the term of this Agreement (but no more often than once per calendar year in the absence of the occurrence and continuance of an Event of Default), Borrowers will
provide, at Borrowers’ sole expense, an inspection or audit, to be conducted by an engineering or consulting firm approved by Agent, of the properties owned or operated by any or all of the Borrowers, indicating the compliance by Borrowers with
all Environmental Laws.

amounts which, under the provisions of any ERISA Plan, agreement relating thereto or applicable law, any Borrower or any ERISA Affiliate is required to pay as contributions thereto; (4) permit to exist, or allow any Subsidiary to permit to

ERISA Plan resulting in an increase in current liability such that any Borrower or any ERISA Affiliate is required to provide security to such ERISA Plan under section 401(a)(29) of the Code; or (11) permit to exist any occurrence of any
“reportable event” (as defined in Title IV of ERISA), or any other event or condition, which presents a material (in 

  

 45 

 
the opinion of the Majority Lenders) risk of such a termination by the PBGC of any ERISA Plan that could reasonably be expected to result in a Material
Adverse Effect upon any Obligated Person. 
 (l) Environmental Matters. Neither any Borrower nor any Guarantor Subsidiary will cause
or permit any Borrower, any Guarantor Subsidiary or any property owned or used by any Borrower or any Guarantor Subsidiary to be in violation, in any material respect, of any Environmental Law. Neither any Borrower nor any Guarantor Subsidiary will

Adverse Effect, assuming full disclosure to the applicable governmental authorities of all relevant facts, conditions and circumstances. Neither any Borrower nor any Guarantor Subsidiary will cause or permit the disposal or other release of any
hazardous substance, hazardous waste or solid waste (as defined in the Environmental Laws) on or to any of the Borrower Property except in compliance with all Environmental Laws. 
 (m) Distributions. IMLLC will not make any Distributions, except as follows (and such exceptions shall not apply if, immediately before,
immediately after or as of the end of the Fiscal Quarter in which any such Distribution shall have occurred, any Default shall have occurred and be continuing): (1) for any Fiscal Year of IMLLC, at or within 30 days before the times when taxes
(or estimated taxes) are due and payable by the ultimate owners of IMLLC (up to and including April 15 of the succeeding calendar year), IMLLC may make Distributions in an aggregate amount not greater than the product of: (A) the highest
tax rate payable on ordinary taxable income under the tax laws of the United States, plus the highest tax rate payable on ordinary taxable income under the tax laws of the State of Colorado, the State of Utah or the State of New Mexico, whichever is
greatest, times (B) the taxable income of IMLLC for such Fiscal Year, to the extent that such taxable income is required to be included in the taxable income of the ultimate owners of IMLLC (or, if such taxable income is not known at such time,
the then-current estimate of such taxable income; provided that when the actual taxable income of IMLLC is determined for any Fiscal Year, an Event of Default shall be deemed to have occurred unless the owners of IMLLC repay to IMLLC, within 30 days
after IMLLC determines that excess Distributions have been made, any Distributions made pursuant to this clause (1) for such Fiscal Year that exceed 110 percent of the amount distributable under this clause (1) for such Fiscal Year, as
calculated using the actual taxable income of IMLLC for such Fiscal Year), (2) IMLLC may make a Distribution at a time when the Cash Flow Leverage Ratio (Distributions) of IMLLC and its Consolidated Affiliates shall not be greater than 2.0:1.0
immediately before and immediately after such Distribution and as of both the beginning and the end of the Fiscal Quarter in which such Distribution shall have occurred, (3) an in-kind Distribution of the membership interests in IOG and/or
IMLLC’s interests in oil and gas leases and related equipment and facilities formerly owned by IOG, or (4) a Distribution of up to 10 percent of the proceeds received by IMLLC from any issuance of equity in IMLLC that occurs within six
months after the date of this Agreement. In calculating the taxable income of IMLLC for purposes of this Section 6.2(m), costs that are capitalized for GAAP purposes but that are passed through to members of IMLLC who then separately elect to
deduct or capitalize such 

  

 46 

 
costs on their tax returns, will be deemed to be capitalized and amortized over the statutory period. 
 (n) Reorganizations; Combinations. Except for the conversion of IMLLC to a Delaware limited liability company in accordance with
Section 6.1(e) above, neither any Borrower nor any Guarantor Subsidiary will change its name or the nature of its business, reorganize, liquidate, dissolve or enter into any merger, joint venture, partnership or other combination; provided that
Lenders will not unreasonably withhold their consent to a merger of IPMLLC, IPNMLLC or IPWLLC into IMLLC so long as Borrowers execute and deliver any and all amendments of the Loan Documents reasonably required by Agent, on behalf of Lenders, in
connection therewith and such merger does not, in the reasonable opinion of Lenders, adversely affect the prospects for repayment of either of the Loans. 
 (o) Hedging Transactions. Borrowers and Guarantor Subsidiaries, in the aggregate, will not at any time have entered into or have become party to any one or more Hedging Activities except for: (1) Hedging
Activities in amounts not in excess of 80 percent of the volume, as projected at the times such Hedging Activities are entered into, of Borrowers’ and Guarantor Subsidiaries’ consumption of natural gas, other hydrocarbons or electricity
(timed in accordance with Borrowers’ and Guarantor Subsidiaries’ expected usage rates of natural gas, other hydrocarbons or electricity), according to the then most recent forecasts submitted pursuant to Section 6.1(b)(6) above, as
such forecasts may be modified or supplemented from time to time by notice from Borrowers to Agent; (2) Hedging Activities effectively converting interest rates from floating to fixed or from shorter-term fixed to longer-term fixed, so long as
the notional amounts of such Hedging Activities do not exceed, at the time such Hedging Activities are entered into, the lesser of (A) the forecast aggregate debt level of IMLLC on a Consolidated basis for the time periods covered by such
Hedging Activities, or (B) $120,000,000; (3) Hedging Activities required pursuant to Section 6.1(q) above; and (4) Hedging Activities consented to in writing by Majority Lenders. 
 (p) Additional Subsidiaries. No Borrower shall, nor shall any Borrower permit any of its Subsidiaries to, create or acquire any additional
Subsidiaries (except the Solution Mining Sub) without: (1) the prior written consent of Agent, (2) such new Subsidiary executing and delivering to Agent, at its request, a Guaranty and such other Security Documents, all in form and
substance reasonably satisfactory to Agent, as Agent may reasonably request, (3) the equity holder of such Subsidiary executing and delivering to Agent a Security Document pledging all equity interests in such Subsidiary along with the
certificates pledged thereby, if any, and appropriately executed powers in blank, if applicable, all in form and substance reasonably satisfactory to Agent, and (4) the delivery by Borrowers and each Subsidiary of any certificates, opinions of
counsel, title opinions or other documents as Agent may reasonably request relating to such Subsidiary, all in form and substance reasonably satisfactory to Agent.

any such property, regardless of whether the act, omission, event or circumstance constituted a violation of any Environmental Law at the time of its existence or occurrence, and (d) any and all claims or proceedings (whether brought by a
private party or governmental agencies) for bodily injury, property damage, abatement or remediation, environmental damage or impairment or any other injury or damage resulting from or relating to any hazardous or toxic substance, solid waste or
contaminated material located upon or migrating into, from or through any property owned or operated by any Borrower (whether or not the release of such materials was caused by any Borrower, a tenant or subtenant or a prior owner, tenant or
subtenant on any such property and whether or not the alleged liability is attributable to the handling, storage, generation, transportation, removal or disposal of such substance, waste or material or the mere presence of such substance, waste or
material on any such property), for which Agent or any Lender may have liability due to the making of the Loans, the granting of the Security Documents, the exercise of Agent’s or any Lender’s rights under the Loan Documents or otherwise.
WITHOUT LIMITATION, IT IS THE INTENTION OF BORROWERS, AND BORROWERS AGREE, THAT THE FOREGOING INDEMNITIES SHALL APPLY TO EACH INDEMNIFIED PARTY WITH RESPECT TO CLAIMS, DEMANDS, LIABILITIES, LOSSES, DAMAGES, CAUSES OF ACTION, JUDGMENTS, PENALTIES,
COSTS AND EXPENSES (INCLUDING WITHOUT LIMITATION REASONABLE ATTORNEYS’ FEES) WHICH IN WHOLE OR IN PART ARE CAUSED BY OR ARISE OUT OF THE NEGLIGENCE (BUT NOT THE GROSS NEGLIGENCE, BAD FAITH OR WILLFUL MISCONDUCT) OF SUCH (AND/OR ANY OTHER)
INDEMNIFIED PARTY. However, such indemnities shall not apply to any particular 
  

 50 

 
indemnified party (but shall apply to the other indemnified parties) to the extent the subject of the indemnification is caused by or arises out of the gross
negligence or willful misconduct of such particular indemnified party. The foregoing indemnities shall not terminate upon the Release Date or upon the release, foreclosure or other termination of the Security Documents, but will survive the Release
Date, foreclosure of the Security Documents or conveyances in lieu of foreclosure, and the repayment of the Loans and the discharge and release of the Security Documents and the other documents evidencing and/or, securing the Loans. 
 ARTICLE VIII 
 Agent 
 Section 8.1. Appointment; Nature of Relationship. USB is hereby appointed by each of Lenders as Agent hereunder and under each other Loan
Document, and each of Lenders irrevocably authorizes Agent to act as the contractual representative of such Lender with the rights and duties expressly set forth herein and in the other Loan Documents. Agent agrees to act as administrative agent
upon the express conditions contained in this Article VIII. Notwithstanding the use of the defined term “Agent,” it is expressly understood and agreed that Agent shall not have any fiduciary responsibilities to any Lender by reason of this
Agreement or any other Loan Document and that Agent is merely acting as the contractual representative of Lenders with only those duties as are expressly set forth in this Agreement and the other Loan Documents. In its capacity as Agent:
(a) Agent does not assume any fiduciary duties to any of Lenders, (b) Agent is a “representative” of Lenders within the meaning of Section 9-105 of the Uniform Commercial Code, and (c) Agent is acting as an independent
contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the other Loan Documents. Each of Lenders hereby agrees to assert no claim against Agent on any agency theory or any other theory of liability
for breach of fiduciary duty, all of which claims each Lender hereby waives. 
 Section 8.2. Powers. Agent shall have and may
exercise such powers under the Loan Documents as are specifically delegated to Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. Agent shall not have any implied duties to Lenders, or any obligation
to Lenders to take any action thereunder except any action specifically provided by the Loan Documents to be taken by Agent. 
 Section 8.3. General Immunity. Neither Agent nor any of Agent’s directors, officers, agents or employees shall be liable to any Borrower or any Lender for any action taken or omitted to be taken by it or them hereunder or
under any other Loan Document or in connection herewith or therewith except to the extent such action or inaction is determined in a final non-appealable judgment by a court of competent jurisdiction to have arisen from the bad faith, gross
negligence or willful misconduct of such Person. 
 Section 8.4. No Responsibility for Loans, Recitals, etc. Neither Agent nor
any of Agent’s directors, officers, agents or employees shall be responsible to any Lender for or have any duty to any Lender to ascertain, inquire into, or verify: (a) any statement, warranty or representation made in connection with any
Loan Document or any borrowing hereunder, (b) the 

  

 51 

 
performance or observance of any of the covenants or agreements of any obligor under any Loan Document, including any agreement by an obligor to furnish
information directly to each Lender, (c) the satisfaction of any condition specified in Article IV, except for the receipt of items required to be delivered solely to Agent, (d) the existence or possible existence of any Default,
(e) the validity, enforceability, effectiveness, sufficiency or genuineness of any Loan Document or any other instrument or writing furnished in connection therewith, or (f) the financial condition of any Borrower or of any Borrower’s
Subsidiaries. Agent shall not have any duty to disclose to Lenders information that is not required to be furnished by Borrowers to Agent at such time, but is voluntarily furnished by any Borrower to Agent (either in its capacity as Agent or in its
individual capacity). 
 Section 8.5. Action on Instructions of Lenders. Agent shall in all cases be fully protected in acting,
or in refraining from acting, hereunder and under any other Loan Document in accordance with written instructions signed by the Majority Lenders (or, when expressly required hereunder, all Lenders), and such instructions and any action taken or
failure to act pursuant thereto shall be binding on all Lenders. Lenders hereby acknowledge that Agent shall not be under any duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other
Loan Document unless it shall be requested in writing to do so by the Majority Lenders. Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Document unless it shall first be indemnified to its
satisfaction by Lenders (ratably in accordance with their respective Percentage Shares) against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action. 
 Section 8.6. Employment of Agents and Counsel. Agent may execute any of its duties as Agent hereunder and under any other Loan Document by or
through employees, agents, and attorneys-in-fact and shall not be answerable to Lenders, except as to money or securities received by it or its authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it
with reasonable care. Agent shall be entitled to the advice of counsel concerning the contractual arrangement between Agent and Lenders and all matters pertaining to Agent’s duties hereunder and under any other Loan Document. 
 Section 8.7. Reliance on Documents; Counsel. Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit, letter,
telegram, statement, paper or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and, in respect to legal matters, upon the opinion of counsel selected by Agent, which counsel may be
employees of Agent. 
 Section 8.8. Agent’s Reimbursement and Indemnification. Lenders agree to reimburse and indemnify
Agent, ratably in accordance with their respective Percentage Shares: (a) for any amounts not reimbursed by Borrowers for which Agent is entitled to reimbursement by Borrowers under the Loan Documents, (b) for any other expenses incurred
by Agent on behalf of Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents (including for any expenses incurred by Agent in connection with any dispute between Agent and any Lender or
between two or more of Lenders), and (c) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or 

  

 52 

 
disbursements of any kind and nature whatsoever which may be imposed upon, incurred by or asserted against Agent in any way relating to or arising out of the
Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including for any such amounts incurred by or asserted against Agent in connection with any dispute between Agent and any Lender or
between two or more of Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents. THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT CAUSED,
IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT; PROVIDED ONLY THAT NO LENDER SHALL BE OBLIGATED UNDER THIS SECTION TO INDEMNIFY AGENT FOR THAT PORTION, IF ANY, OF ANY LIABILITIES AND COSTS WHICH IS PROXIMATELY CAUSED BY
AGENT’S OWN INDIVIDUAL GROSS NEGLIGENCE, BAD FAITH OR WILLFUL MISCONDUCT, AS DETERMINED IN A FINAL NON-APPEALABLE JUDGMENT. The obligations of Lenders under this Section 8.8 shall survive payment of the Obligations and termination of this
Agreement. 
 Section 8.9. Notice of Default. Agent shall not be deemed to have knowledge or notice of the occurrence of any
Default hereunder unless Agent has received written notice from a Lender or Borrowers referring to this Agreement describing such Default and stating that such notice is a “notice of default”. In the event that Agent receives such a
notice, Agent shall give prompt notice thereof to Lenders. 
 Section 8.10. Rights as a Lender. In the event Agent is a Lender,
Agent shall have the same rights and powers hereunder and under any other Loan Document with respect to its Commitment and its Loans as any Lender and may exercise the same as though it were not Agent, and the term “Lender” or
“Lenders” shall, at any time when Agent is a Lender, unless the context otherwise indicates, include Agent in its individual capacity. Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of
trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any other Loan Document, with any Borrower or any Borrower’s Subsidiaries in which such Borrower or such Subsidiary is not restricted hereby from
engaging with any other Person. Agent, in its individual capacity, is not obligated to remain a Lender. 
 Section 8.11. Lender
Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon Agent or any other Lender and based upon the financial statements prepared by Borrowers and such other documents and information as it has deemed
appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon Agent or any other Lender and based upon such
documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement and the other Loan Documents. 
 Section 8.12. Successor Agent. Agent may resign at any time by giving written notice thereof to Lenders and Borrowers, such resignation to be
effective upon the appointment of a successor Agent, or, if no successor Agent has been appointed, forty-five days after the retiring Agent gives notice of its intention to resign. Upon any resignation of Agent, the Majority 

  

 53 

 
Lenders shall have the right (with, so long as no Default exists, the consent of Borrowers, which shall not be unreasonably withheld) to appoint, on behalf
of Borrowers and Lenders, a successor Agent. If no successor Agent shall have been so appointed by the Majority Lenders within thirty days after the resigning Agent’s giving notice of its intention to resign, then the resigning Agent may
appoint, on behalf of Borrowers and Lenders, a successor Agent. Notwithstanding the previous sentence, Agent may at any time without the consent of any Lender and with the consent of Borrowers, not to be unreasonably withheld or delayed, appoint any
of its Affiliates which is a commercial bank as a successor Agent hereunder. If Agent has resigned or been removed and no successor Agent has been appointed, Lenders may perform all the duties of Agent hereunder and Borrowers shall make all payments
in respect of the Obligations to the applicable Lender and for all other purposes shall deal directly with Lenders. No successor Agent shall be deemed to be appointed hereunder until such Agent has accepted the appointment. Any such successor Agent
shall be a commercial bank having capital and retained earnings of at least $100,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the resigning Agent. Upon the effectiveness of the resignation or removal of Agent, the resigning Agent shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the
effectiveness of the resignation of Agent, the provisions of this Article VIII shall continue in effect for the benefit of the such Person in respect of any actions taken or omitted to be taken by such Person while such Person was acting as Agent
hereunder and under the other Loan Documents. In the event that there is a successor to Agent by merger, or Agent assigns its duties and obligations to an Affiliate pursuant to this Section 8.12, then the term “Prime Rate” as used in
this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent. 
 Section 8.13. Delegation to
Affiliates. Borrowers and Lenders agree that Agent may delegate any of its duties under this Agreement to any of its respective Affiliates. Any such Affiliate (and such Affiliate’s directors, officers, agents and employees) which performs
duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which Agent is entitled under Articles VII and VIII. 
 Section 8.14. Other Agents. No Lender identified on the cover page or the signature pages of this Agreement or otherwise herein, or in any
amendment hereof or other document related hereto, as being the “Syndication Agent”, a “Co-Documentation Agent”, a “Managing Agent” or a “Co-Agent” shall have any right, power, obligation, liability,
responsibility or duty under this Agreement in such capacity other than those applicable to all Lenders. Each Lender acknowledges that it has not relied, and will not rely, on any Person so identified in deciding to enter into this Agreement or in
taking or refraining from taking any action hereunder or pursuant hereto. 
 Section 8.15. Withholding and Withholding
Certificates. Lenders agree that Agent shall deduct and withhold from payments made to Lenders such amounts as are required under applicable United States federal income tax Laws and state or local tax Laws. The amount to be deducted and
withheld by Agent may be reduced or eliminated if, prior to any payment each Lender has provided Agent with any and all appropriate withholding forms as described in Section 3.7 above. 
  

 54 

 Section 8.16. Decisions by Lenders. Notwithstanding anything to the contrary contained
herein, any and all decisions to be made and actions to be taken by Lenders hereunder or under any of the Loan Documents (including without limitation any consent in connection with, waiver of or amendment to, any covenant or any acceleration of the
maturity of any of the Loans) may be made or taken by Majority Lenders on behalf of all Lenders; provided that the agreement of Lenders holding Percentage Shares of 100 percent shall be required in order to: (a) waive or consent to any default
in the timely payment of principal or interest, (b) approve any release of any of the Collateral, (c) change any interest rate or fee payable with respect to the applicable Loan, (d) increase the Aggregate Lenders’ Commitment,
(e) change the Percentage Share (Revolving), the Percentage Share (Term) or the Percentage Share of any Lender or the Commitment of any Lender (other than by a transfer involving such Lender made in accordance with this Article VIII) or the
definition of Majority Lenders, (f) extend the Maturity Date (Revolving) or the Maturity Date (Term), or (g) consent to any Distribution by IMLLC. 
 Section 8.17. Benefit of Article VIII. The provisions of this Article are intended solely for the benefit of Agent and Lenders, and no Obligated Person shall be entitled to rely on any such provision or
assert any such provision in a claim or defense against Agent or any Lender. Agent and Lenders may waive or amend such provisions as they desire without any notice to or consent of any Obligated Person; provided that any such waiver or amendment
shall not impose on any Obligated Person any additional liability, obligation or requirement. 
 ARTICLE IX 
 Setoff; Ratable Payments 
 Section 9.1. Setoff. In addition to, and without limitation of, any rights of Lenders under applicable law, if any Borrower becomes insolvent, however evidenced, or any Default occurs, any and all deposits (including all account
balances, whether provisional or final and whether or not collected or available) and any other Debt at any time held or owing by any Lender or any Affiliate of any Lender to or for the credit or account of any Borrower may be offset and applied
toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any part thereof, shall then be due. 
 Section 9.2. Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its share of the Loans (other than payments received pursuant to Article II above) in a greater proportion than that
received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Loans held by the other Lenders so that after such purchase each Lender will hold its proper share of all Loans. If any Lender, whether in
connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such
action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their proper shares of the Loans. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be
made.

 ARTICLE X 
 Benefit of Agreement; Assignments; Participations 
 Section 10.1. Successors and Assigns.
The terms and provisions of the Loan Documents shall be binding upon and shall inure to the benefit of Agent, Borrowers and Lenders and their respective successors and assigns, except that: (a) no Borrower shall have the right to assign its
rights or obligations under the Loan Documents and (b) any assignment by any Lender must be made in compliance with Section 10.3. The parties to this Agreement acknowledge that clause (b) of the foregoing sentence relates only to
absolute assignments and does not prohibit assignments creating security interests, including any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank; provided that no
such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 10.3. Agent may treat the Person which
made any Loan or which holds any Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 10.3; provided that Agent may in its discretion (but shall not be required to) follow instructions from the
Person which made any Loan or which holds any Note to direct payments relating to such Loan or Note to another Person. Any assignee of the rights to any Loan or any Note agrees by acceptance of such assignment to be bound by all of the terms and
provisions of this Agreement and any and all other Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Loan (whether or not a
Note has been issued in evidence thereof), shall be conclusive and binding upon any subsequent holder or assignee of the rights to such Loan. 
 Section 10.2. Participations. (a) Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time sell to one or more banks or other Persons (“Participants”) participating
interests in any Loan owing to such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under this Agreement or any other Loan Documents. In the event of any such sale by a Lender of a
participating interest to a Participant, such Lender’s obligations under this Agreement and the other Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such
obligations, such Lender shall remain the owner of its Loans and the holder of any Note issued to it in evidence thereof for all purposes under this Agreement and the other Loan Documents, all amounts payable by Borrowers under this Agreement shall
be determined as if such Lender had not sold such participating interests, and Borrowers and Agent shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the
other Loan Documents. 
 (b) Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment,
modification or waiver of any provision of this Agreement and any and all other Loan Documents. 
 Section 10.3. Assignments. (a)
Any Lender may, in the ordinary course of its business and in accordance with applicable law, at any time assign to one or more banks or other Persons 

  

 56 

 
(“Purchasers”) all or any part of its rights and obligations under this Agreement and the other Loan Documents. Any such assignment shall be made
in the form of Exhibit H attached hereto and made part hereof. The consents of Borrowers and Agent (which consents shall not be unreasonably withheld or delayed by any such party) shall be required prior to an assignment becoming effective with
respect to a Purchaser which is not a Lender or an Affiliate thereof; provided that if an Event of Default shall have occurred and shall be continuing, the consent of Borrowers shall not be required; provided, further, that no assignment shall be
permitted if, as of the date thereof, any event or circumstance exists that would result in Borrowers being obligated to pay any greater amount hereunder to the Purchaser than Borrowers are obligated to pay to the assigning Lender. Each such
assignment with respect to a Purchaser which is not a Lender or an Affiliate thereof shall (unless Borrowers and Agent otherwise consent) be in an amount not less than the lesser of: (1) $5,000,000 or (2) the entire remaining amount of the
assigning Lender’s Commitment (Revolving) or Commitment (Term) and any and all outstanding Loans and participations in Letters of Credit. 
 (b) Upon: (1) delivery to Agent of an assignment, together with any consents required by Section 10.3(a), and (2) payment of a $3,500 fee to Agent for processing such assignment, such assignment shall become effective on the
effective date specified in such assignment. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Agreement and any other Loan Document executed by or on behalf of Lenders and shall have
all the rights and obligations of a Lender under this Agreement and the other Loan Documents, to the same extent as if it were an original party hereto, and no further consent or action by Borrowers, Lenders or Agent shall be required to release the
transferor Lender with respect to the portion of the Loans and the Commitment assigned to such Purchaser. Upon the consummation of any assignment to a Purchaser pursuant to this Section 10.3(b), the transferor Lender, Agent and Borrowers shall
make appropriate arrangements so that a replacement Note is issued to such transferor Lender and a new Note or, as appropriate, a replacement Note, is issued to such Purchaser, in each case in the appropriate face amounts to reflect the adjustments
in their respective Commitments. 
 Section 10.4. Dissemination of Information. Borrowers authorize each Lender to disclose to
any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a “Transferee”) and any prospective Transferee any and all information in such Lender’s possession concerning the
creditworthiness of Borrowers and their Subsidiaries, including any information contained in any reports delivered hereunder. 
 ARTICLE XI

 Miscellaneous 
 Section 11.1. Waiver and Amendment. No failure or delay by Agent or any Lender in exercising any right, power or remedy which it may have under any of the Loan Documents shall operate as a waiver thereof or of any other right,
power or remedy, nor shall any single or partial exercise by Agent or any Lender of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No waiver of any provision of any Loan
Document and no consent to any departure therefrom shall ever be effective against 

  

 57 

 
Agent or Lenders unless it is in writing and signed by Agent and Lenders, and then such waiver or consent shall be effective only in the specific instances
and for the purposes for which given and to the extent specified in such writing. No notice to or demand on Borrowers shall in any case of itself entitle Borrowers to any other or further notice or demand in similar or other circumstances. No
modification or amendment of or supplement to this Agreement or the other Loan Documents shall be valid or effective unless the same is in writing and signed by the party against whom it is sought to be enforced. 
 Section 11.2. Survival of Agreements; Cumulative Nature. All of Borrowers’ various representations, warranties, covenants and agreements
in the Loan Documents shall survive the execution and delivery of this Agreement and the other Loan Documents and the performance hereof and thereof, including without limitation the making or granting of either of the Loans and the delivery of the
Notes and the other Loan Documents, and shall further survive until all of the Obligations are paid in full to each Lender and all of Agent’s and each Lender’s obligations to Borrowers are terminated. All statements and agreements
contained in any certificate or other instrument delivered to Agent or any Lender under any Loan Document shall be deemed representations and warranties by Borrowers to Agent, on behalf of Lenders, and/or agreements and covenants of Borrowers under
this Agreement. The representations, warranties, and covenants made by the Obligated Persons in the Loan Documents, and the rights, powers, and privileges granted to Agent or any Lender in the Loan Documents, are cumulative, and no Loan Document
shall be construed in the context of another to diminish, nullify, or otherwise reduce the benefit to Agent or any Lender of any such representation, warranty, covenant, right, power or privilege. In particular and without limitation, no exception
set out in this Agreement to any representation, warranty or covenant herein contained shall apply to any similar representation, warranty or covenant contained in any other Loan Document, and each such similar representation, warranty or covenant
shall be subject only to those exceptions which are expressly made applicable to it by the terms of the various Loan Documents. 
 Section 11.3. Notices. All notices, requests, consents, demands and other communications required or permitted under any Loan Document shall be in writing and, unless otherwise specifically provided in such Loan Document, shall
be deemed sufficiently given or furnished if delivered by personal delivery, by facsimile, by expedited delivery service with proof of delivery, or by registered or certified United States mail, return receipt requested, postage prepaid, at the
address specified for Borrower in the Disclosure Schedule or the address provided for Agent or any Lender in Schedule I attached hereto and made a part hereof (unless changed by similar notice in writing given by the Person whose address is to be
changed). Any such notice or communication shall be deemed to have been given upon receipt. 
 Section 11.4. Joint and Several
Liability; Parties in Interest. All obligations of Borrowers hereunder shall be the joint and several, and not merely joint, obligations of each Borrower. All grants, covenants and agreements contained in the Loan Documents shall bind and inure
to the benefit of the parties thereto and their respective permitted successors and assigns. 
 Section 11.5. Governing Law. The
Loan Documents shall be deemed contracts and instruments made under the laws of the State of Colorado and shall be construed and enforced in 

  

 58 

 
accordance with and governed by the laws (other than choice-of-law rules) of the State of Colorado and the laws of the United States of America, except:
(a) to the extent that the law of another jurisdiction is expressly elected in a Loan Document, and (b) with respect to specific Liens, or the perfection thereof, evidenced by Security Documents covering real or personal property which by
the laws applicable thereto are required to be construed under the laws of another jurisdiction. Each Borrower hereby irrevocably submits itself to the non-exclusive jurisdiction of the state and federal courts of the State of Colorado. 

Section 11.6. Limitation on Interest. Agent, Lenders and Borrowers intend to contract in strict compliance with applicable usury law from
time to time in effect. In furtherance thereof such persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall ever be construed to create a contract to pay, for the use, forbearance or detention of
money, interest in excess of the maximum amount of interest permitted to be charged by applicable law from time to time in effect. No Obligated Person shall ever be liable for unearned interest thereon or shall ever be required to pay interest
thereon in excess of the maximum amount that may be lawfully charged under applicable law from time to time in effect, and the provisions of this Section 11.6 shall control over all other provisions of the Loan Documents which may be in
conflict or apparent conflict herewith. Each of Agent and Lenders expressly disavows any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated. If: (a) the
maturity of any Obligation is accelerated for any reason, (b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) any Lender or any other holder of
any or all of the Obligations shall otherwise collect moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be charged by
applicable law then in effect, then all such sums determined to constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at Agent’s
option, promptly returned to Borrowers or the other payor thereof upon such determination. 
 Section 11.7. Waiver of Jury Trial,
Punitive Damages, etc. EACH OF THE OBLIGATED PERSONS, AGENT AND LENDERS HEREBY KNOWINGLY, VOLUNTARILY, INTENTIONALLY AND IRREVOCABLY: (a) WAIVES, TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN
RESPECT OF ANY LITIGATION BASED HEREON, OR DIRECTLY OR INDIRECTLY AT ANY TIME ARISING OUT OF, UNDER OR IN CONNECTION WITH THE LOAN DOCUMENTS OR ANY TRANSACTION CONTEMPLATED THEREBY OR ASSOCIATED THEREWITH, BEFORE OR AFTER MATURITY; (b) WAIVES,
TO THE MAXIMUM EXTENT NOT PROHIBITED BY LAW, ANY RIGHT IT MAY HAVE TO CLAIM OR RECOVER IN ANY SUCH LITIGATION ANY SPECIAL, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, OR DAMAGES OTHER THAN, OR IN ADDITION TO, ACTUAL DAMAGES; (c) CERTIFIES
THAT NO PARTY HERETO NOR ANY REPRESENTATIVE OR AGENT OR COUNSEL FOR ANY PARTY HERETO HAS REPRESENTED, EXPRESSLY OR OTHERWISE, OR IMPLIED THAT SUCH PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVERS, AND
(d) ACKNOWLEDGES THAT IT HAS BEEN INDUCED TO ENTER INTO 

  

 59 

 
THIS AGREEMENT, THE OTHER LOAN DOCUMENTS AND THE TRANSACTIONS CONTEMPLATED HEREBY AND THEREBY BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS
CONTAINED IN THIS SECTION. 
 Section 11.8. USA Patriot Act. Each Lender that is subject to the USA Patriot Act and Agent (for
itself and not on behalf of any Lender) hereby notifies each Borrower that, pursuant to the requirements of the USA Patriot Act, it is required to obtain, verify and record information that identifies such Borrower, which information includes the
name and address of such Borrower and other information that will allow such Lender or Agent, as applicable, to identify such Borrower in accordance with the USA Patriot Act. 
 Section 11.9. Release. Upon full payment and satisfaction of the Loans and all other amounts due in connection therewith as provided herein,
the parties shall thereupon automatically each be fully, finally and forever released and discharged from any further claim, liability or obligation in connection with the Loans, except that the indemnities contained in Sections 7.3 and 8.8 above
shall survive. 
 Section 11.10. Severability. If any term or provision of any Loan Document shall be determined to be illegal or
unenforceable, all other terms and provisions of the Loan Documents shall nevertheless remain effective and shall be enforced to the full extent permitted by applicable law. 
 Section 11.11. Counterparts. This Agreement may be separately executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to constitute one and the same Agreement. 
 Section 11.12.
Conflicts. To the extent of any irreconcilable conflicts between the provisions of this Agreement and the provisions of any of the other Loan Documents, the provisions of this Agreement shall prevail. 
 Section 11.13. Entire Agreement. This Agreement, the Notes, the Security Documents and the other Loan Documents from time to time executed in
connection herewith state the entire agreement between the parties with respect to the subject matter hereof. 
 Section 11.14.
Facsimile Delivery. Delivery of this Agreement and any and all other documents to be delivered in connection with this Agreement by any party other than Agent may be effected, without limitation, by faxing a signed counterpart of the
signature page of this Agreement or such other document to Agent (any party that effects delivery in such manner hereby agreeing to transmit promptly to Agent actual signed counterparts in such number as Agent may require). 
 Section 11.15. Supersession. At the time of the Initial Advance, the terms and provisions of this Agreement and the Notes shall supersede the
terms and provisions of the Existing USB Credit Agreement, the Existing USB Note and the related documents evidencing the Existing USB Loan in their entirety; provided that, except as specifically amended and restated by any of the Security
Documents, the security documents executed and delivered in 

  

 60 

 
connection with the Existing USB Credit Agreement shall remain in full force and effect and shall secure the Obligations.

 NOW, THEREFORE, in consideration of $10.00 and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as follows: 
  

	 	1.	Credit Agreement. The Credit Agreement shall be, and hereby is, amended as follows as of the date hereof: 

  

	 	a.	The following shall be substituted for the definition of “Aggregate Lenders’ Commitment (Revolving)” in Section 1.1 on page 2 of the Credit Agreement:

 “Aggregate Lenders’ Commitment (Revolving)” means, at any time, the sum of the
Commitments (Revolving) of all Lenders at that time; provided that, upon the request of Borrowers, unless Agent is aware, either at the time of such request or at any time prior to its implementation, of the occurrence and continuation of an uncured
Event of Default, Agent may agree to increase said amount to a maximum of $125,000,000, so long as Agent is able to obtain sufficient additional Commitments (Revolving) from Lenders (including then-existing Lenders and third parties willing to
become Lenders hereunder) to fund any such increase. 
  

 1 

	 	b.	In lines 3 and 4 of the definition of “Collateral” in Section 1.1 on page 4 of the Credit Agreement, “or of any Borrower” shall be deleted.

  

	 	c.	The following shall be substituted for the definition of “Commitment (Revolving)” in Section 1.1 on page 4 of the Credit Agreement:

Commitment (Revolving) that such Lender has agreed to fund, minus (d) any portion of such Lender’s Initial Commitment (Revolving) that it has assigned to any other Lender pursuant to Section 10.3 below, minus (e) any reduction in
such Lender’s Commitment (Revolving) pursuant to Section 2.6 below. 
  

	 	d.	The following shall be substituted for the definition of “Guarantor Subsidiary” in Section 1.1 on page 8 of the Credit Agreement:

a Guaranty and/or any Security Document as provided in Section 6.2(p) below.

such net cash proceeds are used for the Solution Mining Project. 
  

	 	h.	In line 2 of Section 2.2(a) on page 19 of the Credit Agreement, “Initial Commitment (Term)” shall be substituted for “Percentage Share (Term)”.

Lenders”. 

  

 2

	 	k.	The following shall be inserted at the end of Section 6.1(b)(6) on page 37 of the Credit Agreement: “provided that other information satisfactory to Agent may be submitted
