The Company and the Trustee
agree as follows for the benefit of each other and for the equal and ratable benefit of the Holders (as defined below) of the Company’s
6.125% Senior Notes due 2024 (as further defined herein, the “Notes”):

 

Article
I

DEFINITIONS
AND INCORPORATION BY REFERENCE

 

Section
1.01         Definitions.

 

“144A Global
Note” means a global note substantially in the form of Exhibit A hereto bearing the Global Note Legend and the Private
Placement Legend and deposited with or on behalf of, and registered in the name of, the Depositary or its nominee that shall be
issued in a denomination equal to the outstanding principal amount of the Notes sold in reliance on Rule 144A.

 

“Acquired
Indebtedness” means Indebtedness (i) of a Person or any of its Subsidiaries existing at the time such Person becomes
or is merged with and into a Restricted Subsidiary or (ii) assumed in connection with the acquisition of assets from such
Person, in each case whether or not Incurred by such Person in connection with, or in anticipation or contemplation of, such Person
becoming a Restricted Subsidiary or such acquisition. Acquired Indebtedness shall be deemed to have been Incurred, with respect
to clause (i) of the preceding sentence, on the date such Person becomes or is merged with and into a Restricted Subsidiary
and, with respect to clause (ii) of the preceding sentence, on the date of consummation of such acquisition of assets.

 

“Additional
Assets” means:

 

(1)         any
properties or assets to be used by the Company or a Restricted Subsidiary in the Oil and Gas Business;

 

(2)         the
Capital Stock of a Person that becomes a Restricted Subsidiary as a result of the acquisition of such Capital Stock by the Company
or a Restricted Subsidiary; or

 

(3)         Capital
Stock constituting a minority interest in any Person that at such time is a Restricted Subsidiary;

“Additional
Notes” means any further Notes (other than  the Initial Notes and  any Exchange Notes issued in exchange for
the Initial Notes) issued under this Indenture in accordance with the terms of this Indenture, including Sections 2.01(f), 2.02,
2.17 and 4.07, as part of the same series as the Initial Notes, ranking equally with those Initial Notes and having identical terms
to the Initial Notes (except that there may be differences in the date of issuance,  the issue price,  rights under a
related Registration Rights Agreement, if any,  at the option of the Company, as to the payment of interest accruing prior
to the issue date of such Additional Notes, and  the first payment of interest following the issue date of such Additional
Notes), subject to compliance with Article II. The Initial Notes, any Additional Notes subsequently issued under this Indenture
and all Exchange Notes issued in exchange therefor shall be treated as a single class of securities for all purposes under this
Indenture, including, without limitation, directions, waivers, amendments, consents, redemptions and offers to purchase.

 

“Adjusted
Consolidated Net Tangible Assets” of the Company means (without duplication), as of the date of determination, the remainder
of:

 

(a)          the
sum of:

 

(1)         discounted
future net revenues from proved oil and gas reserves of the Company and its Restricted Subsidiaries calculated in accordance with
SEC guidelines before any state or federal income taxes (“pre-tax”), as estimated by the Company or its outside engineers
in a reserve report prepared as of the end of the Company’s most recently completed fiscal year for which audited financial
statements are available, as increased by, as of the date of determination, the estimated discounted future net revenues from:

 

(A)         estimated
proved oil and gas reserves acquired since such year end, which reserves were not reflected in such year end reserve report, and

 

(B)         estimated
oil and gas reserves attributable to extensions, discoveries and other additions and upward revisions of estimates of proved oil
and gas reserves since such year end due to exploration, development or exploitation, production or other activities, which would,
in accordance with standard industry practice, cause such revisions (including the impact to proved reserves and future net revenues
from estimated development costs incurred and the accretion of discount since such year end),

 

and decreased by, as of the date of determination,
the estimated discounted future net revenues from:

 

(C)         estimated
proved oil and gas reserves produced or disposed of since such year end, and

 

(D)         estimated
oil and gas reserves attributable to downward revisions of estimates of proved oil and gas reserves since such year end due to
changes in geological conditions or other factors which would, in accordance with standard industry practice, cause such revisions,
in each case calculated on a pre-tax basis and in accordance with SEC guidelines,

 

and in the case of clauses (A) through
(D) utilizing prices and costs calculated in accordance with SEC guidelines as of such year end; provided, however,
that in the case of each of the determinations made pursuant to clauses (A) through (D), such increases and decreases may
be as estimated by the Company’s petroleum engineers;

 

    	2

    	 

    

 

(2)         the
capitalized costs that are attributable to Oil and Gas Properties of the Company and its Restricted Subsidiaries to which no proved
oil and gas reserves are attributable, based on the Company’s books and records as of a date no earlier than the date of
the Company’s latest available annual or quarterly financial statements;

 

(3)         the
Net Working Capital of the Company and its Restricted Subsidiaries on a date no earlier than the date of the Company’s latest
annual or quarterly financial statements; and

 

(4)         the
greater of

 

(A)         the
net book value of other tangible assets of the Company and its Restricted Subsidiaries, as of a date no earlier than the date of
the Company’s latest annual or quarterly financial statements, and

 

(B)         the
appraised value, as estimated by independent appraisers, of other tangible assets of the Company and its Restricted Subsidiaries,
as of a date no earlier than the date of the Company’s latest audited financial statements; provided, that, if no
such appraisal has been performed, the Company shall not be required to obtain such an appraisal and only clause (4)(A) of
this definition shall apply;

 

minus

 

(b)          the
sum of:

 

(1)         Minority
Interests;

 

(2)         any
net gas balancing liabilities of the Company and its Restricted Subsidiaries reflected in the Company’s latest annual or
quarterly balance sheet (to the extent not deducted in calculating Net Working Capital of the Company in accordance with clause
(a)(3) above of this definition);

 

(3)         to
the extent included in (a)(1) above, the discounted future pre-tax net revenues, calculated in accordance with SEC guidelines
(utilizing prices and costs calculated in accordance with SEC guidelines as of such year end), attributable to reserves which are
required to be delivered to third parties to fully satisfy the obligations of the Company and its Restricted Subsidiaries with
respect to Volumetric Production Payments (determined, if applicable, using the schedules specified with respect thereto); and

 

(4)         to
the extent included in (a)(1) above, the discounted future pre-tax net revenues, calculated in accordance with SEC guidelines,
attributable to reserves subject to Dollar-Denominated Production Payments which, based on the estimates of production and price
assumptions included in determining the discounted future net revenues specified in (a)(1) above, would be necessary to fully
satisfy the payment obligations of the Company and its Subsidiaries with respect to such Dollar-Denominated Production Payments
(determined, if applicable, using the schedules specified with respect thereto).

 

    	3

    	 

    

 

If the Company changes its method of accounting
from the full cost method of accounting to the successful efforts or a similar method, “Adjusted Consolidated Net Tangible
Assets” will continue to be calculated as if the Company were still using the full cost method of accounting.

common control with such specified Person. For the purposes of this definition, “control” when used with respect to

of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings
correlative to the foregoing.

 

“Agent”
means any Registrar or Paying Agent.

 

“Applicable
Premium” means, with respect to any Note on any applicable redemption date, the greater of:

(2)         the
excess, if any, of:

 

(a)          the
present value at such redemption date of (i) the redemption price of such Note at October 1, 2019 (as set forth in the table
in Section 3.07(a) of this Indenture), plus (ii) all required interest payments (excluding accrued and unpaid
interest to such redemption date) due on such Note through October 1, 2019, computed using a discount rate equal to the Treasury
Rate as of such redemption date plus 50 basis points; over

 

(b)          the
principal amount of such Note.

 

“Applicable
Procedures” means, with respect to any transfer or exchange of or for beneficial interests in any Global Note, the rules and
procedures of the Depositary, Euroclear and Clearstream that apply to such transfer or exchange.

 

“Asset Disposition”
means any direct or indirect sale, lease (including by means of Production Payments and Reserve Sales and a Sale/Leaseback Transaction),
transfer, issuance or other disposition, or a series of related sales, leases, transfers, issuances or dispositions that are part
of a common plan, of (a) shares of Capital Stock of a Restricted Subsidiary (other than Preferred Stock of Restricted Subsidiaries
issued in compliance with Section 4.07 and directors’ qualifying shares or shares required by applicable law to be held by
a Person other than the Company or a Restricted Subsidiary), (b) all or substantially all the assets of any division or line
of business of the Company or any Restricted Subsidiary (excluding any division or line of business the assets of which are owned
by an Unrestricted Subsidiary) or (c) any other assets of the Company or any Restricted Subsidiary outside the ordinary course

however, that:

 

(1)         if
the transaction giving rise to the need to calculate the Consolidated Coverage Ratio is an Incurrence of Indebtedness, Consolidated
EBITDA and Consolidated Interest Expense for such period will be calculated after giving effect on a pro forma basis to such Indebtedness
and the use of proceeds thereof as if such Indebtedness had been Incurred on the first day of such period and such proceeds had
been applied as of such date;

 

(2)         if
the Company or any Restricted Subsidiary has Incurred, repaid, repurchased, defeased or otherwise discharged any Indebtedness (other
than working capital borrowings under a revolving credit facility) since the beginning of the period, Consolidated EBITDA and Consolidated
Interest Expense for such period will be calculated after giving effect on a pro forma basis to such Incurrence, repayment, repurchase,
defeasement or other discharge of Indebtedness as if such Incurrence, repayment, repurchase, defeasement or other discharge had
occurred on the first day of such period;

 

(3)         if,
since the beginning of such period, the Company or any Restricted Subsidiary has made any Asset Disposition or if the transaction
giving rise to the need to calculate the Consolidated Coverage Ratio is such an Asset Disposition, the Consolidated EBITDA for
such period will be reduced by an amount equal to the Consolidated EBITDA (if positive) attributable to the assets which are the
subject of such Asset Disposition for such period or increased by an amount equal to the Consolidated EBITDA (if negative) attributable
thereto for such period and Consolidated Interest Expense for such period shall be reduced by an amount equal to the Consolidated
Interest Expense attributable to any Indebtedness of the Company or any Restricted Subsidiary repaid, repurchased, defeased or
otherwise discharged with respect to the Company and its continuing Restricted Subsidiaries in connection with or with the proceeds
from such Asset Disposition for such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Interest
Expense for such period attributable to the Indebtedness of such Restricted Subsidiary to the extent the Company and its continuing
Restricted Subsidiaries are no longer liable for such Indebtedness after such sale);

 

(4)         if,
since the beginning of such period, the Company or any Restricted Subsidiary (by merger or otherwise) has made an Investment in
any Restricted Subsidiary (or any Person which becomes a Restricted Subsidiary or is merged with or into the Company or a Restricted
Subsidiary) or an acquisition (or will have received a contribution) of assets, including any acquisition or contribution of assets
occurring in connection with a transaction causing a calculation to be made under this Indenture, which constitutes all or substantially
all of a company, division, operating unit, segment, business, group of related assets or line of business or producing Oil and

on the first day of such period; and

of assets that would have required an adjustment pursuant to clause (3) or (4) above if made by the Company or a Restricted
Subsidiary during such period, Consolidated EBITDA and Consolidated Interest Expense for such period will be calculated after giving
pro forma effect thereto as if such Asset Disposition or Investment or acquisition of assets had occurred on the first day of such
period.

 

For purposes of this
definition, whenever pro forma effect is to be given to any calculation under this definition, the pro forma calculations will
be determined in good faith by a responsible financial or accounting officer of the Company in accordance with Regulation S-X under
the Securities Act and related regulations or policies of the SEC, provided, however, that pro forma effect may be given to any
expense and cost reductions or synergies that have occurred or are reasonably expected to occur, in the reasonable judgment of
a Company Officer who serves as principal financial or accounting officer (regardless of whether those cost savings or operating
improvements could then be reflected in pro forma financial statements in accordance with Regulation S-X promulgated under the
Securities Act or any other regulation or policy of the SEC related thereto). If any Indebtedness bears a floating rate of interest
and is being given pro forma effect, the interest expense on such Indebtedness will be calculated as if the average rate in effect
from the beginning of such period to the date of determination had been the applicable rate for the entire period (taking into
account any Interest Rate Agreement applicable to such Indebtedness, but if the remaining term of such Interest Rate Agreement
is less than 12 months, then such Interest Rate Agreement shall only be taken into account for that portion of the period equal
to the remaining term thereof). If any Indebtedness that is being given pro forma effect bears an interest rate at the option of
the Company, the interest rate shall be calculated by applying such optional rate chosen by the Company. Interest on Indebtedness
that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank
offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such
optional rate chosen as the Company may designate.

period not included in the calculation);

period; and less, to the extent included in calculating such Consolidated Net Income and in excess of any costs or expenses attributable

(6)         cash
costs associated with Interest Rate Agreements (including amortization of fees); provided, however, that if Interest Rate
Agreements result in net cash benefits rather than costs, such benefits shall be credited to reduce Consolidated Interest Expense
unless, pursuant to GAAP, such net benefits are otherwise reflected in Consolidated Net Income;

 

(7)         the
consolidated interest expense of the Company and its Restricted Subsidiaries that was capitalized during such period; and

may require a Paying Agent to pay all money held by it to the Trustee. The Company at any time may require a Paying Agent to pay
all money held by it to the Trustee. Upon payment over to the Trustee, the Paying Agent (if other than the Company or one of its

determined not to request such information and that it is aware that the transferor is relying upon its foregoing representations
in order to claim the exemption from registration provided by Rule 144A; (ii) a transfer thereof to an IAI shall be made
upon receipt by the Trustee or its agent of a certificate substantially in the form set forth in Exhibit B-2 hereto from the

a Note is replaced pursuant to Section 2.08, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that
the replaced Note is held by a protected purchaser.

the principal amount of any Note is considered paid under Section 4.01, it ceases to be outstanding and interest on it ceases to

unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Notes in exchange for temporary Notes.

 

(b)          Holders

record date, in each case at the rate provided in the Notes and in Section 4.01. The Company shall notify the Trustee in writing
of the amount of defaulted interest proposed to be paid on each Note and the date of the proposed payment. The Company shall fix
or cause to be fixed each such special record date and payment date, provided that no such special record date shall be less than
10 days prior to the related payment date for such defaulted interest. At least 15 days before the special record date, the Company

such numbers in notices of redemption as a convenience to Holders; provided, that any such notice may state that no representation
is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice of a redemption and
that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption shall not be
affected by any defect in or omission of such numbers. The Company shall promptly notify the Trustee of any change in the “CUSIP”
or “ISIN” numbers.

(b)          If
the Company complies with the provisions of the preceding paragraph, on and after the redemption date, interest shall cease to

Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender
for redemption because of the failure of the Company to comply with the preceding paragraph, interest shall be paid on the unpaid
principal, from the redemption date until such principal is paid, and to the extent lawful on any interest not paid on such unpaid
principal, in each case at the rate provided in the Notes and in Section 4.01.

(e)          The
Company will not permit any of its Unrestricted Subsidiaries to Incur any Indebtedness, or issue any shares of Disqualified Stock,
other than Non-Recourse Debt. If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such
Subsidiary shall be deemed to be Incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted
to be Incurred as of such date under this Section 4.07, the Company shall be in Default of this Section 4.07.

 

(f)          For
purposes of determining compliance with any U.S. dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. dollar-equivalent
principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange
rate in effect on the date such Indebtedness was Incurred, in the case of term Indebtedness, or first committed, in the case of
revolving credit Indebtedness; provided that if such Indebtedness is Incurred to refinance other Indebtedness denominated in a
foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated
at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall
be deemed not to have been exceeded so long as the principal amount of such refinancing Indebtedness does not exceed the principal
amount of such Indebtedness being refinanced. Notwithstanding any other provision of this covenant, the maximum amount of Indebtedness
that the Company may Incur pursuant to this covenant shall not be deemed to be exceeded solely as a result of fluctuations in the
exchange rates of currencies. The principal amount of any Indebtedness Incurred to refinance other Indebtedness, if Incurred in
a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable
to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

 

Section
4.08         Limitation on Restricted Payments.

 

(a)          The
Company will not, and will not permit any of its Restricted Subsidiaries, directly or indirectly, to:

 

(1)         pay
any dividend or make any payment or distribution on or in respect of the Company’s or any Restricted Subsidiaries’
Capital Stock (including any payment or distribution in connection with any merger or consolidation involving the Company or any
of its Restricted Subsidiaries) except:

 

(A)         dividends
or distributions by the Company payable solely in Capital Stock of the Company (other than Disqualified Stock but including options,
warrants or other rights to purchase such Capital Stock of the Company); and

 

(B)         dividends
or distributions payable to the Company or a Restricted Subsidiary and if such Restricted Subsidiary is not a Wholly-Owned Subsidiary,
to minority stockholders (or owners of an equivalent interest in the case of a Subsidiary that is an entity other than a corporation)
so long as the Company or a Restricted Subsidiary receives at least its pro rata share of such dividend or distribution;

 

    	69

    	 

    

 

(2)         purchase,
repurchase, redeem, defease or otherwise acquire or retire for value any Capital Stock of the Company or any direct or indirect
parent of the Company held by Persons other than the Company or a Restricted Subsidiary (other than in exchange for Capital Stock
of the Company (other than Disqualified Stock));

 

(3)         purchase,
repurchase, redeem, defease or otherwise acquire or retire for value, prior to scheduled maturity, scheduled repayment or scheduled
sinking fund payment, any Subordinated Obligations or Guarantor Subordinated Obligations (other than (x) Indebtedness permitted
under clause (3) of Section 4.07(b) of this Indenture or (y) the purchase, repurchase, redemption, defeasance or
other acquisition or retirement of Subordinated Obligations or Guarantor Subordinated Obligations purchased in anticipation of
satisfying a sinking fund obligation, principal installment or final maturity, in each case due within one year of the date of
purchase, repurchase, redemption, defeasance or other acquisition or retirement); or

 

(4)         make
any Restricted Investment in any Person;

 

(any such dividend, distribution, purchase,
redemption, repurchase, defeasance, other acquisition, retirement or Restricted Investment referred to in Sections 4.08(a)(1) through
(4) shall be referred to herein as a “Restricted Payment”), if at the time the Company or such Restricted
Subsidiary makes such Restricted Payment:

 

(A)         a
Default shall have occurred and be continuing (or would result therefrom);

 

(B)         the
Company is not able to Incur an additional $1.00 of Indebtedness pursuant to Section 4.07(a) of this Indenture after giving
effect, on a pro forma basis, to such Restricted Payment; or

 

(C)         the
aggregate amount of such Restricted Payment and all other Restricted Payments declared or made subsequent to December 12, 2013
would exceed the sum of (the “Restricted Payments Basket”):

 

(i)          50%
of Consolidated Net Income for the period (treated as one accounting period) from October 1, 2013 to the end of the most recent
fiscal quarter ending prior to the date of such Restricted Payment for which internal financial statements are in existence (or,
in case such Consolidated Net Income is a deficit, minus 100% of such deficit);

 

(ii)         100%
of the aggregate Net Cash Proceeds and the Fair Market Value of Additional Assets, in each case received by the Company from the
issue or sale of its Capital Stock (other than Disqualified Stock) or other capital contributions to the Company subsequent to
December 12, 2013 (other than Net Cash Proceeds received from an issuance or sale of such Capital Stock to (x) Persons indicated
in clause (5) of Section 4.08(b) or any direct or indirect parent of the Company, to the extent such Net Cash Proceeds
have been used to make a Restricted Payment pursuant to clause (5) of Section 4.08(b), (y) a Subsidiary of the Company
or (z) an employee stock ownership plan, option plan or similar trust (to the extent such sale to an employee stock ownership
plan, option plan or similar trust is financed by loans from or Guaranteed by the Company or any Restricted Subsidiary unless such
loans have been repaid with cash on or prior to the date of determination));

 

    	70

    	 

    

 

(iii)        the
amount by which Indebtedness of the Company or its Restricted Subsidiaries is reduced on the Company’s balance sheet upon
the conversion or exchange (other than by a Subsidiary of the Company) subsequent to December 12, 2013 of any Indebtedness of the
Company or its Restricted Subsidiaries convertible or exchangeable for Capital Stock (other than Disqualified Stock) of the Company
(less the amount of any cash, or the Fair Market Value of any other property (other than such Capital Stock), distributed by the
Company upon such conversion or exchange), together with the net proceeds, if any, received by the Company or any of its Restricted
Subsidiaries upon such conversion or exchange; and

 

(iv)        the
amount equal to the aggregate net reduction in Restricted Investments made by the Company or any of its Restricted Subsidiaries
in any Person after December 12, 2013 resulting from:

 

(A)         repurchases,
repayments or redemptions of such Restricted Investments by such Person, proceeds realized upon the sale of such Restricted Investment
(other than to a Subsidiary of the Company), repayments of loans or advances or other transfers of assets (including by way of
dividend or distribution) by such Person to the Company or any Restricted Subsidiary;

 

(B)         the
redesignation of Unrestricted Subsidiaries as Restricted Subsidiaries (valued in each case as provided in the definition of “Investment”)
not to exceed, in the case of any Unrestricted Subsidiary, the amount of Investments previously made by the Company or any Restricted
Subsidiary in such Unrestricted Subsidiary, which amount in each case under this Section 4.08(a)(4)(C)(iv) was included in
the calculation of the amount of Restricted Payments; provided, however, that no amount will be included under this Section
4.08(a)(4)(C)(iv) to the extent it is already included in Consolidated Net Income; and

 

(C)         the
sale by the Company or any Restricted Subsidiary (other than to the Company or a Restricted Subsidiary) of all or a portion of
the Capital Stock of an Unrestricted Subsidiary or a distribution from an Unrestricted Subsidiary or a dividend from an Unrestricted
Subsidiary (whether any such distribution or dividend is made with proceeds from the issuance by such Unrestricted Subsidiary of
its Capital Stock or otherwise).

 

(b)          Notwithstanding
the foregoing, Section 4.08(a) shall not prohibit the following actions:

 

    	71

    	 

    

 

(1)         any
Restricted Payment made by exchange for, or out of the proceeds of the substantially concurrent sale of, Capital Stock of the Company
(other than Disqualified Stock and other than Capital Stock issued or sold to a Subsidiary of the Company or an employee stock
ownership plan or similar trust to the extent such sale to an employee stock ownership plan or similar trust is financed by loans
from or Guaranteed by the Company or any Restricted Subsidiary unless such loans have been repaid with cash on or prior to the
date of determination) or a substantially concurrent cash capital contribution received by the Company from its shareholders; provided,
however, that (a) such Restricted Payment will be excluded from subsequent calculations of the amount of Restricted Payments
and (b) the Net Cash Proceeds from such sale of Capital Stock or capital contribution will be excluded from Section 4.08(a)(4)(C)(ii);

 

(2)         any
purchase, repurchase, redemption, defeasance or other acquisition or retirement of Subordinated Obligations of the Company or Guarantor

sale of, Refinancing Indebtedness or any purchase, repurchase, redemption, defeasance or other acquisition or retirement of Guarantor
Subordinated Obligations made by exchange for or out of the proceeds of the substantially concurrent sale of Refinancing Indebtedness
that, in each case, is permitted to be Incurred pursuant to Section 4.07 of this Indenture; provided, however, that such
purchase, repurchase, redemption, defeasance, acquisition or retirement will be excluded from subsequent calculations of the amount
of Restricted Payments;

 

(3)         any
purchase, repurchase, redemption, defeasance or other acquisition or retirement of Disqualified Stock of the Company or a Restricted
Subsidiary made by exchange for, or out of the proceeds of the substantially concurrent sale of, Disqualified Stock of the Company
or such Restricted Subsidiary, as the case may be, that, in each case, is permitted to be Incurred pursuant to Section 4.07 of
this Indenture; provided, however, that such purchase, repurchase, redemption, defeasance, acquisition or retirement will
be excluded from subsequent calculations of the amount of Restricted Payments;

 

(4)         dividends
paid or distributions made within 60 days after the date of declaration if at such date of declaration such dividend or distribution
would have complied with this covenant if it had been made on such date; provided, however, that such dividends and distributions
will be included in subsequent calculations of the amount of Restricted Payments; and provided further, however, that for
purposes of clarification, this Section 4.08(b)(4) shall not include cash payments in lieu of the issuance of fractional shares
included in Section 4.08(b)(9) below;

 

(5)         so
long as no Default has occurred and is continuing, the repurchase or other acquisition of Capital Stock (including options, warrants,
equity appreciation rights or other rights to purchase or acquire Capital Stock) of the Company held by any existing or former
employees, officers or directors of the Company or any Restricted Subsidiary of the Company or their assigns, estates or heirs,
in each case pursuant to the repurchase or other acquisition provisions under employee stock option or stock purchase plans or
agreements or other agreements to compensate officers, employees or directors, in each case approved by the Company’s Board
of Directors; provided, that such repurchases or other acquisitions during any calendar year will not exceed $5.0 million
in the aggregate (except that any unused portion of such amount may be carried forward and used in the succeeding calendar years);
provided, that any payment pursuant to this clause (5) will be excluded from subsequent calculations of the amount of Restricted
Payments;

 

    	72

    	 

    

 

(6)         purchases,
repurchases, redemptions or other acquisitions or retirements for value of Capital Stock deemed to occur upon the exercise of stock
options, warrants, rights to acquire Capital Stock or other convertible securities if such Capital Stock represents a portion of
the exercise or exchange price thereof; provided, however, that such acquisitions or retirements will be excluded from subsequent
calculations of the amount of Restricted Payments;

 

(7)         the
purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of any Subordinated Obligation (a) at
a purchase price not greater than 101% of the principal amount of such Subordinated Obligation in the event of a Change of Control
in accordance with provisions similar to Section 4.15 or (b) at a purchase price not greater than 100% of the principal amount
thereof in the event of an Asset Sale in accordance with provisions similar to Section 4.11 of this Indenture; provided,
that prior to or simultaneously with such purchase, repurchase, redemption, defeasance or other acquisition or retirement, the
Company has made the Change of Control Offer or Asset Disposition Offer, as applicable, as provided in Section 4.15 or Section
4.11, as applicable, and has completed the repurchase or redemption of all Notes validly tendered for payment in connection with
such Change of Control Offer or Asset Disposition Offer; provided, however, that such acquisitions or retirements will be
excluded in subsequent calculations of the amount of Restricted Payments;

 

(8)         payments
or distributions to dissenting stockholders pursuant to applicable law or in connection with the settlement or other satisfaction
of legal claims made pursuant to or in connection with a consolidation, merger or transfer of assets; provided, however, that

(9)         cash
payments in lieu of the issuance of fractional shares in connection with a merger or similar transaction or conversion or exchange
of securities, in each case that are permitted under the Indenture; provided, however, that any payment pursuant to this
Section 4.08(b)(9) shall be excluded in the calculation of the amount of Restricted Payments;

 

(10)        the
payment of scheduled or accrued dividends to holders of any class of or series of Disqualified Stock of the Company issued on or
after the Issue Date in accordance with Section 4.07, to the extent such dividends are included in Consolidated Interest Expense;
provided, however, that any payment pursuant to this Section 4.08(b)(10) shall be excluded in the calculation of the
amount of Restricted Payments;

 

(11)        Restricted
Payments in an amount not to exceed $75.0 million in the aggregate since December 12, 2013; provided, however, that the
amount of such Restricted Payments will be excluded in subsequent calculations of the amount of Restricted Payments.

 

In the event that a restricted
payment meets the criteria of more than one of the exceptions described in clauses (1) through (11) above or is entitled
to be made pursuant to Section 4.08(a), the Company shall, in its sole discretion, subdivide and classify, and may later reclassify,
such Restricted Payment in any manner that complies with this covenant.

 

    	73

    	 

    

 

(c)          The
amount of all Restricted Payments (other than cash) shall be the Fair Market Value on the date of such Restricted Payment of the
asset(s) or securities proposed to be paid, transferred or issued by the Company or such Restricted Subsidiary, as the case
may be, pursuant to such Restricted Payment. The Fair Market Value of any cash Restricted Payment shall be its face amount and
the Fair Market Value of any non-cash Restricted Payment shall be determined in accordance with the definition of that term.

 

(d)          For
the purpose of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by the Company
and its Restricted Subsidiaries (except to the extent repaid) in the Subsidiary so designated will be deemed to be an Investment
in an amount determined as set forth in the last sentence of the definition of “Investment.” Such designation will
be permitted only if a Restricted Payment in such amount would be permitted at such time, whether pursuant to Section 4.08(a) or
under clause (11) of Section 4.08(b), or pursuant to the definition of “Permitted Investments,” and if such Subsidiary
otherwise meets the definition of an Unrestricted Subsidiary.

 

Section
4.09         Limitation on Liens.

 

(a)          The
Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, Incur or suffer
to exist any Lien (the “Initial Lien”) other than Permitted Liens upon any of its property or assets (including
Capital Stock of Restricted Subsidiaries), including any income or profits therefrom, whether owned on the date of this Indenture
or acquired after that date, which Lien is securing any Indebtedness, unless contemporaneously with the Incurrence of such Liens
effective provision is made to secure the Indebtedness due under the Notes or, in respect of Liens on any Restricted Subsidiary’s
property or assets, any Subsidiary Guarantee of such Restricted Subsidiary, equally and ratably with (or senior in priority to
in the case of Liens with respect to Subordinated Obligations or Guarantor Subordinated Obligations, as the case may be) the Indebtedness
secured by such Lien for so long as such Indebtedness is so secured.

 

(b)          Any
Lien created for the benefit of the Holders of the Notes pursuant to Section 4.09(a) above shall provide by its terms that
such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien.

 

Section
4.10         Limitation on Restrictions on Distributions from Restricted
Subsidiaries.

 

(a)          The
Company will not, and will not permit any Restricted Subsidiary to, create or otherwise cause or permit to exist or become effective
any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to:

 

(1)         pay
dividends or make any other distributions on its Capital Stock or pay any Indebtedness or other obligations owed to the Company
or any Restricted Subsidiary (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating
distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a restriction on the
ability to make distributions on Capital Stock);

 

    	74

    	 

    

 

(2)         make
any loans or advances to the Company or any Restricted Subsidiary (it being understood that the subordination of loans or advances
made to the Company or any Restricted Subsidiary to other Indebtedness Incurred by the Company or any Restricted Subsidiary shall
not be deemed a restriction on the ability to make loans or advances); or

 

(3)         sell,
lease or transfer any of its property or assets to the Company or any Restricted Subsidiary.

 

(b)          However,
Section 4.10(a) will not prohibit:

 

(1)         any
encumbrance or restriction pursuant to or by reason of an agreement in effect at or entered into on the Issue Date, including,
without limitation, this Indenture as in effect on such date;

 

(2)         any
encumbrance or restriction with respect to a Person pursuant to or by reason of an agreement relating to any Capital Stock or Indebtedness
Incurred by a Person on or before the date on which such Person was acquired by the Company or another Restricted Subsidiary (other
than Capital Stock or Indebtedness Incurred as consideration in, or to provide all or any portion of the funds utilized to consummate,
the transaction or series of related transactions pursuant to which such Person was acquired by the Company or a Restricted Subsidiary
or in contemplation of the transaction) and outstanding on such date; provided, that any such encumbrance or restriction
shall not extend to any assets or property of the Company or any other Restricted Subsidiary other than the assets and property
so acquired;

 

(3)         encumbrances
and restrictions contained in contracts entered into in the ordinary course of business, not relating to any Indebtedness, and
that do not, individually or in the aggregate, detract from the value of, or from the ability of the Company and the Restricted
Subsidiaries to realize the value of, property or assets of the Company or any Restricted Subsidiary in any manner material to
the Company or any Restricted Subsidiary;

 

(4)         any
encumbrance or restriction with respect to an Unrestricted Subsidiary pursuant to or by reason of an agreement that the Unrestricted
Subsidiary is a party to entered into before the date on which such Unrestricted Subsidiary became a Restricted Subsidiary; provided,
that such agreement was not entered into in anticipation of the Unrestricted Subsidiary becoming a Restricted Subsidiary and any
such encumbrance or restriction shall not extend to any assets or property of the Company or any other Restricted Subsidiary other
than the assets and property so acquired;

 

(5)         any
encumbrance or restriction with respect to a Restricted Subsidiary pursuant to an agreement effecting a refunding, replacement
or refinancing of Indebtedness Incurred pursuant to an agreement referred to in clauses (1) through (4), clause (10) or this
clause (5) of this Section 4.10(b) or contained in any amendment, restatement, modification, renewal, supplemental, refunding,
replacement or refinancing of an agreement referred to in clauses (1) through (4), clause (10) or this clause (5) of this
Section 4.10(b); provided, that the encumbrances and restrictions with respect to such Restricted Subsidiary contained in
any such agreement taken as a whole are no less favorable in any material respect to the Holders of the Notes than the encumbrances
and restrictions contained in the agreements governing the Indebtedness being refunded, replaced or refinanced;

 

    	75

    	 

    

 

(6)         in
the case of clause (3) of Section 4.10(a) above, any encumbrance or restriction:

 

(A)         that
restricts in a customary manner the subletting, assignment or transfer of any property or asset that is subject to a lease (including
leases governing leasehold interests or farm-in agreements or farm-out agreements relating to leasehold interests in Oil and Gas
Properties), license or similar contract, or the assignment or transfer of any such lease (including leases governing leasehold
interests or farm-in agreements or farm-out agreements relating to leasehold interests in Oil and Gas Properties), license (including,
without limitation, licenses of intellectual property) or other contract;

 

(B)         contained
in mortgages, pledges or other security agreements permitted under this Indenture securing Indebtedness of the Company or a Restricted
Subsidiary to the extent such encumbrances or restrictions restrict the transfer of the property subject to such mortgages, pledges
or other security agreements;

 

(C)         contained
in any agreement creating Hedging Obligations permitted from time to time under this Indenture;

 

(D)         pursuant
to customary provisions restricting dispositions of real property interests set forth in any reciprocal easement agreements of
the Company or any Restricted Subsidiary;

 

(E)         restrictions
on cash or other deposits imposed by customers under contracts entered into in the ordinary course of business; or

 

(F)         provisions
with respect to the disposition or distribution of assets or property in operating agreements, joint venture agreements, development
agreements, area of mutual interest agreements and other agreements that are customary in the Oil and Gas Business and entered
into in the ordinary course of business;

 

(7)         any
encumbrance or restriction contained in (a) purchase money obligations for property acquired in the ordinary course of business
and (b) Capitalized Lease Obligations permitted under this Indenture, in each case, that impose encumbrances or restrictions
of the nature described in clause (3) of Section 4.10(a) on the property so acquired;

 

(8)         any
encumbrance or restriction with respect to a Restricted Subsidiary (or any of its property or assets) imposed pursuant to an agreement
entered into for the direct or indirect sale or disposition of all or a portion of the Capital Stock or assets of such Restricted
Subsidiary (or the property or assets that are subject to such restriction) pending the closing of such sale or disposition;

 

(9)         encumbrances
or restrictions arising or existing by reason of applicable law or any applicable rule, regulation or order;

 

    	76

    	 

    

 

(10)        encumbrances
or restrictions contained in agreements governing Indebtedness of the Company or any of its Restricted Subsidiaries permitted to
be Incurred pursuant to an agreement entered into subsequent to the Issue Date in accordance with Section 4.07; provided,
that the provisions relating to such encumbrance or restriction contained in such Indebtedness are not materially less favorable
to the Holders of Notes taken as a whole, as determined by the Board of Directors of the Company in good faith, than the provisions
contained in the Credit Agreement and in this Indenture as in effect on the Issue Date;

 

(11)        encumbrances
or restrictions contained in agreements entered into in connection with the Credit Agreement as amended from time to time, or the
Existing Senior Notes as amended from time to time, that apply during the occurrence of a continuing default or event of default
under the Credit Agreement or Existing Senior Notes;

 

(12)        the
issuance of Preferred Stock by a Restricted Subsidiary or the payment of dividends thereon in accordance with the terms thereof;
provided, that issuance of such Preferred Stock is permitted pursuant to Section 4.07 and the terms of such Preferred Stock
do not expressly restrict the ability of a Restricted Subsidiary to pay dividends or make any other distributions on its Capital
Stock (other than requirements to pay dividends or liquidation preferences on such Preferred Stock prior to paying any dividends
or making any other distributions on such other Capital Stock); and

 

(13)        restrictions
on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business.

 

Section
4.11         Limitation on Sales of Assets and Subsidiary Stock.

 

(a)          The
Company will not, and will not permit any of its Restricted Subsidiaries to, make any Asset Disposition unless:

 

(1)         the
Company or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Disposition at least
equal to the Fair Market Value (such Fair Market Value to be determined on the date of contractually agreeing to such Asset Disposition)
of the shares or other assets subject to such Asset Disposition; and

 

(2)         at
least 75% of the aggregate consideration received by the Company or such Restricted Subsidiary, as the case may be, from such Asset
Disposition and all other Asset Dispositions since December 12, 2013, on a cumulative basis, is in the form of cash or Cash Equivalents
or Additional Assets, or any combination thereof.

 

(b)          The
Net Available Cash from such Asset Disposition may be applied, within 365 days from the later of the date of such Asset Disposition
or the receipt of such Net Available Cash, by the Company or such Restricted Subsidiary, as the case may be:

 

(1)         to
prepay, repay, redeem or purchase Pari Passu Indebtedness of the Company (including the Notes) or a Subsidiary Guarantor or any
Indebtedness (other than Disqualified Stock) of a Restricted Subsidiary that is not a Subsidiary Guarantor (in each case, excluding
Indebtedness owed to the Company or an Affiliate of the Company); provided, however, that, in connection with any prepayment,
repayment, redemption or purchase of Indebtedness pursuant to this Section 4.11(b)(1), the Company or such Restricted Subsidiary
will retire such Indebtedness and will cause the related commitment (if any) to be permanently reduced in an amount equal to the
principal amount so prepaid, repaid, redeemed or purchased; or

 

    	77

    	 

    

 

(2)         to
make capital expenditures in the Oil and Gas Business or to invest in Additional Assets;

 

provided, that pending the final
application of any such Net Available Cash in accordance with clause (1) or clause (2) of this Section 4.11(b), the Company
and its Restricted Subsidiaries may temporarily reduce Indebtedness or otherwise invest such Net Available Cash in any manner not
prohibited by this Indenture. The requirement of clause (2) of this Section 4.11(b) shall be deemed to be satisfied if an
agreement committing to make the acquisition or expenditure referred to therein is entered into by the Company or a Restricted
Subsidiary within the specified time period and such Net Available Cash is subsequently applied in accordance with such agreement
within six months following such agreement.

 

(c)          Any
Net Available Cash from Asset Dispositions that is not applied or invested as provided in Section 4.11(b) will be deemed to
constitute “Excess Proceeds.” Not later than the 366th day from the later of the date of such Asset Disposition
or the receipt of such Net Available Cash, if the aggregate amount of Excess Proceeds exceeds $20.0 million, the Company will be
required to make an offer (“Asset Disposition Offer”) to all Holders of Notes and, to the extent required by
the terms of other Pari Passu Indebtedness, to all holders of other Pari Passu Indebtedness outstanding with similar provisions
requiring the Company to make an offer to purchase such Pari Passu Indebtedness with the proceeds from any Asset Disposition (“Pari
Passu Notes”) to purchase the maximum principal amount of Notes and any such Pari Passu Notes to which the Asset Disposition
Offer applies that may be purchased out of the Excess Proceeds, at an offer price in cash in an amount equal to 100% of the principal
amount (or, in the event such Pari Passu Indebtedness of the Company was issued with significant original issue discount, 100%
of the accreted value thereof) of the Notes and Pari Passu Notes plus accrued and unpaid interest, if any (or in respect of such
Pari Passu Indebtedness, such lesser price, if any, as may be provided for by the terms of such Indebtedness), to the date of purchase
(subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment
Date), in accordance with the procedures set forth in this Indenture or the agreements governing the Pari Passu Notes, as applicable,
in each case in minimum principal amount of $2,000 and integral multiples of $1,000 in excess of $2,000. If the aggregate principal
amount of Notes surrendered by Holders thereof and other Pari Passu Notes surrendered by Holders or lenders, collectively, exceeds
the amount of Excess Proceeds, the Trustee shall select the Notes to be purchased on a pro rata basis on the basis of the aggregate
principal amount of tendered Notes and Pari Passu Notes. To the extent that the aggregate principal amount of Notes and Pari Passu
Notes so validly tendered and not properly withdrawn pursuant to an Asset Disposition Offer is less than the Excess Proceeds, the
Company may use any remaining Excess Proceeds for general corporate purposes, subject to the Articles IV and V of this Indenture.
Upon completion of such Asset Disposition Offer, the amount of Excess Proceeds shall be reset at zero.

 

    	78

    	 

    

 

(d)          The
Asset Disposition Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that
a longer period is required by applicable law (the “Asset Disposition Offer Period”). No later than five Business
Days after the termination of the Asset Disposition Offer Period (the “Asset Disposition Purchase Date”), the
Company will purchase the principal amount of Notes and Pari Passu Notes required to be purchased pursuant to this Section 4.11
(the “Asset Disposition Offer Amount”) or, if less than the Asset Disposition Offer Amount has been so validly
tendered and not properly withdrawn, all Notes and Pari Passu Notes validly tendered and not properly withdrawn in response to
the Asset Disposition Offer.

 

(e)          If
the Asset Disposition Purchase Date is on or after an interest record date and on or before the related Interest Payment Date,
any accrued and unpaid interest, if any, will be paid to the Person in whose name a Note is registered at the close of business
on such record date, and no further interest will be payable to Holders who tender Notes pursuant to the Asset Disposition Offer.

 

(f)          On
or before the Asset Disposition Purchase Date, the Company will, to the extent lawful, accept for payment, on a pro rata basis
to the extent necessary, the Asset Disposition Offer Amount of Notes and Pari Passu Notes or portions of Notes and Pari Passu Notes
so validly tendered and not properly withdrawn pursuant to the Asset Disposition Offer, or if less than the Asset Disposition Offer
Amount has been validly tendered and not properly withdrawn, all Notes and Pari Passu Notes so validly tendered and not properly
withdrawn, in each case in minimum principal amount of $2,000 and integral multiples of $1,000 in excess of $2,000. The Company
will deliver to the Trustee an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment
by the Company in accordance with the terms of this Section 4.11 and, in addition, the Company will deliver all certificates and
notes required, if any, by the agreements governing the Pari Passu Notes. The Company or the paying agent, as the case may be,
will promptly (but in any case not later than five Business Days after the termination of the Asset Disposition Offer Period) mail
or deliver to each tendering Holder of Notes or holder or lender of Pari Passu Notes, as the case may be, an amount equal to the
purchase price of the Notes or Pari Passu Notes so validly tendered and not properly withdrawn by such holder or lender, as the
case may be, and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon delivery
of an Officers’ Certificate from the Company, will authenticate and mail or deliver such new Note to such Holder, in a principal
amount equal to any unpurchased portion of the Note surrendered; provided, that each such new Note will be in a minimum
principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. In addition, the Company will take any and all
other actions required by the agreements governing the Pari Passu Notes. Any Note not so accepted will be promptly mailed or delivered
by the Company to the Holder thereof. The Company will publicly announce the results of the Asset Disposition Offer on the Asset
Disposition Purchase Date.

 

(g)          The
Company will comply, to the extent applicable, with the requirements of Rule 14e-1 of the Exchange Act and any other securities
laws or regulations in connection with the repurchase of Notes pursuant to an Asset Disposition Offer. To the extent that the provisions
of any securities laws or regulations conflict with provisions of this Section 4.11, the Company will comply with the applicable
securities laws and regulations and will not be deemed to have breached its obligations under this Indenture by virtue of its compliance
with such securities laws or regulations.

(h)          For
the purposes of clause (2) of Section 4.11(a) above, the following will be deemed to be cash:

 

(1)         the
assumption by the transferee of Indebtedness or other obligations appearing on the consolidated balance sheet of the Company (other
than Subordinated Obligations or Disqualified Stock) of the Company or Indebtedness or other obligations of a Restricted Subsidiary
appearing on the consolidated balance sheet of the Company (other than Guarantor Subordinated Obligations or Disqualified Stock
of any Restricted Subsidiary that is a Subsidiary Guarantor) and the release of the Company or such Restricted Subsidiary from
all liability on such Indebtedness or other liability in connection with such Asset Disposition (in which case the Company will,
without further action, be deemed to have applied such deemed cash to Indebtedness in accordance with Section 4.11(b)(1)); and

 

(2)         securities,
notes or other obligations received by the Company or any Restricted Subsidiary from the transferee that are converted by the Company

(a)          The
Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, enter into, make, amend or
conduct any transaction (including making a payment to, the purchase, sale, lease or exchange of any property or the rendering
of any service), contract, agreement or understanding with or for the benefit of any Affiliate of the Company (an “Affiliate
Transaction”) unless:

 

(1)         the
terms of such Affiliate Transaction are not materially less favorable to the Company or such Restricted Subsidiary, as the case
may be, than those that could reasonably be expected to be obtained in a comparable transaction at the time of such transaction
in arm’s-length dealings with a Person who is not such an Affiliate or if, in the good faith judgment of the Board of Directors,
no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is otherwise
fair to the Company or the Restricted Subsidiary, from a financial point of view; and

 

(2)         either:
(a) if such Affiliate Transaction involves an aggregate consideration in excess of $20.0 million but not greater than $50.0
million, the Company delivers to the Trustee an Officers’ Certificate certifying that such Affiliate Transaction satisfies
the criteria in Section 4.12(a)(1) above, or (b) if such Affiliate Transaction involves an aggregate consideration in
excess of $50.0 million, the Company delivers to the Trustee an Officers’ Certificate certifying that such Affiliate Transaction
satisfies the criteria in Section 4.12(a)(1) above and that the terms of such transaction have been approved by a majority
of the members of the Board of Directors of the Company having no personal pecuniary interest in such transaction.

 

    	80

    	 

    

 

(b)          Section
4.12(a) shall not apply to and does not prohibit:

of the definition thereof;

 

(2)         any
issuance of Capital Stock (other than Disqualified Stock), or other payments, awards or grants in cash, Capital Stock (other than

(3)         loans
or advances to employees, officers or directors in the ordinary course of business of the Company or any of its Restricted Subsidiaries
not to exceed $5.0 million in the aggregate at any one time outstanding;

 

(4)         advances
to or reimbursements of employees for moving, entertainment and travel expenses, drawing accounts and similar expenditures in the

or any of its Restricted Subsidiaries is a party as of or on the Issue Date, as these agreements may be amended, modified, supplemented,
extended or renewed from time to time; provided, however, that any future amendment, modification, supplement, extension
or renewal entered into after the Issue Date will be permitted only to the extent that its terms are not materially more disadvantageous,
taken as a whole, to the Holders of the Notes than the terms of the agreements in effect on the Issue Date;

 

    	81

    	 

    

 

(11)        transactions
with customers, clients, suppliers, joint interest owners or purchasers or sellers of goods or services, in each case in the ordinary
course of business and otherwise in compliance with the terms of this Indenture, provided that in the reasonable determination
of the Board of Directors of the Company or the senior management of the Company, such transactions are on terms not materially
less favorable to the Company or the relevant Restricted Subsidiary than those that could reasonably be expected to be obtained
in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Company;

 

(12)        transactions

Company or such direct or indirect parent company, as the case may be, on any matter involving such other Person; and

 

(13)        any
transaction in which the Company or any of its Restricted Subsidiaries delivers to the Trustee a letter from an accounting, appraisal

the form specified in Annex E to this Indenture) pursuant to which such Subsidiary will unconditionally Guarantee, on a joint and
several basis, the full and prompt payment of the principal of, premium, if any, and interest on the Notes on a senior basis. 
Any such Subsidiary Guarantee will be subject to the release and other provisions of Article X.

 

Section
4.14         Business Activities.

 

The Company will not,
and will not permit any of its Restricted Subsidiaries to, engage in any business activity other than the Oil and Gas Business,

Section
4.15         Offer to Repurchase Upon a Change of Control.

 

(a)          If
a Change of Control occurs, unless the Company has previously or concurrently exercised its right to redeem all of the Notes pursuant

multiple of $1,000 in excess of $2,000) of such Holder’s Notes at a purchase price in cash equal to 101% of the principal
amount of the Notes plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of Holders of record
on the relevant record date to receive interest due on the relevant Interest Payment Date).

 

    	82

    	 

    

 

(b)          Within
30 days following any Change of Control, unless the Company has previously or concurrently exercised its right to redeem all of
the Notes pursuant to Section 3.07, the Company will mail a notice (the “Change of Control Offer”) to each Holder,
with a copy to the Trustee, stating, among other things:

 

(1)         that
a Change of Control has occurred and that such Holder has the right to require the Company to purchase such Holder’s Notes
at a purchase price in cash equal to 101% of the principal amount of such Notes plus accrued and unpaid interest, if any, to the
date of purchase (subject to the right of Holders of record on a record date to receive interest on the relevant Interest Payment
Date) (the “Change of Control Payment”);

 

(2)         the
repurchase date (which shall be no earlier than 30 days nor later than 60 days from the date such notice is mailed) (the “Change
of Control Payment Date”);

 

(3)         that
any Note not properly tendered will remain outstanding and continue to accrue interest;

 

(4)         that
unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change
of Control Offer will cease to accrue interest on the Change of Control Payment Date;

Day preceding the Change of Control Payment Date;

 

(6)         that
Holders will be entitled to withdraw their tendered Notes and their election to require the Company to purchase such Notes, provided,
that the paying agent receives, not later than the close of business on the Business Day preceding the Change of Control Payment
Date, a telegram, telex, facsimile transmission or letter complying with the requirements of Section 4.15(f) below;

 

(7)         that
if the Company is repurchasing a portion of the Note of any Holder, the Holder will be issued a new Note equal in principal amount
to the unpurchased portion of the Note surrendered, provided, that the unpurchased portion of the Note must be equal to
a minimum principal amount of $2,000 and an integral multiple of $1,000 in excess of $2,000; and

 

(8)         other
procedures determined by the Company, consistent with this Indenture, that a Holder must follow in order to have its Notes repurchased.

 

(c)          On
the Change of Control Payment Date, the Company will:

 

    	83

    	 

    

 

(1)         accept
for payment all Notes or portions of Notes (in a minimum principal amount of $2,000 and integral multiples of $1,000 in excess
of $2,000) properly tendered pursuant to the Change of Control Offer and not properly withdrawn;

 

(2)         deposit
with the paying agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes accepted for
payment, provided, however, that the funds once deposited are to be uninvested until disbursed pursuant to this Section
4.15; and

 

(3)         deliver
or cause to be delivered to the Trustee the Notes so accepted together with an Officers’ Certificate stating the aggregate
principal amount of Notes or portions of Notes being purchased by the Company.

 

(d)          The
paying agent will promptly mail or deliver to each Holder of Notes accepted for payment the Change of Control Payment for such
Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Note
equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided, that each such new Note
will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000.

 

(e)          If
the Change of Control Payment Date is on or after an interest record date and on or before the related Interest Payment Date, any
accrued and unpaid interest, will be paid to the Person in whose name a Note is registered at the close of business on such record
date, and no further interest will be payable to Holders who tender pursuant to the Change of Control Offer.

 

(f)          A
tender made in response to a Change of Control Offer may be withdrawn if the Company receives, not later than the third Business
Day prior to the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter, specifying, as applicable:
(1) the name of the Holder; (2) the certificate number of the Note in respect of which such notice of withdrawal is being

if any, of such Note (which shall be $2,000 or whole multiples of $1,000 in excess thereof) that remains subject to the original
Change of Control Offer and that has been or will be delivered for purchase by the Company.

 

(g)          The
Trustee and the Paying Agent shall return to the Company, upon its request, any cash that remains unclaimed for two years after
a Change of Control Payment Date together with interest or dividends, if any, thereon (subject to Section 7.01(f)), held by them
for the payment of the Change of Control Payment; and the Holder of such tendered and accepted Note shall thereafter look only
to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such cash, and all liability
of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent,
before being required to make any such repayment, shall at the expense of the Company comply with the SEC Regulation 17AD-17 as
it applies to lost bondholders; provided, further however, that (x) to the extent that the aggregate amount of cash
deposited by the Company pursuant to Section 4.15(c)(2) exceeds the aggregate Change of Control Payment of the Notes or portions
thereof to be purchased, then the Trustee shall hold such excess for the Company and (y) unless otherwise directed by the
Company in writing, promptly after the Business Day following the Change of Control Payment Date the Trustee shall return any such
excess to the Company together with interest, if any, thereon (subject to Section 7.01(f)).

 

    	84

    	 

    

 

(h)          The
Company will comply, to the extent applicable, with the requirements of Rule 14e-1 under the Exchange Act and any other securities
laws or regulations in connection with a Change of Control Offer. To the extent that the provisions of any securities laws or regulations
conflict with this Section 4.15, the Company will comply with the applicable securities laws and regulations and will not be deemed
to have breached its obligations under this Section 4.15 by virtue of such conflict.

 

(i)          Notwithstanding
the foregoing, the Company shall not be required to make a Change of Control Offer (i) upon a Change of Control if a third
party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth
in this Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not
withdrawn under such Change of Control Offer or (ii) if notice of redemption for 100% of the aggregate principal amount of
the outstanding Notes has been given pursuant to Section 3.07, unless and until there is a default in payment of the applicable
redemption price.

 

(j)          In
the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes validly tender and do not
withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of
the Company pursuant to Section 4.15(i) above, purchases all of the Notes validly tendered and not withdrawn by such Holders,
the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following
the purchase pursuant to the Change of Control Offer described under this Section 4.15, to redeem all of the Notes that remain
outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Payment plus, to the
extent not included in the Change of Control Payment, accrued and unpaid interest, if any, to the date of redemption.

 

(k)          A
Change of Control Offer may be made in advance of a Change of Control, and conditioned upon the occurrence of a Change of Control,
if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

 

Section
4.16         Termination of Covenants.

 

In the event that at
any time an Investment Grade Rating Event has occurred, the Company and its Restricted Subsidiaries will no longer be subject to
the provisions of this Indenture described under Sections 4.07, 4.08, 4.10, 4.11 and 4.12. In addition, the Company will no longer
be subject to the financial test set forth in Section 5.01(a)(3).  Following the termination of the covenants listed in this
Section 4.16, the Company may not designate any of its Subsidiaries as Unrestricted Subsidiaries.

 

    	85

    	 

    

 

Section
4.17         Payment of Additional Amounts.

 

(a)          All
payments under or with respect to the Notes or this Indenture or pursuant to any future Subsidiary Guarantee shall be made free
and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment
or other governmental charge (including penalties, interest and other liabilities related thereto) (collectively, “Taxes”)
imposed or levied by or on behalf of any Canadian government (or, with respect to any Subsidiary Guarantor incorporated or organized
outside the United States or Canada, the government of the country in which such Subsidiary Guarantor is incorporated or organized)
or political subdivision or territory or possession of any government or authority or agency therein or thereof having the power
to tax (each a “Taxing Authority”), unless the obligor thereon is required to withhold or deduct Taxes under any law
or by the interpretation, application or administration thereof.

 

(b)          If
any such obligor is so required to withhold or deduct any amount of or on account of Taxes imposed by a Taxing Authority from any
payment made under or with respect to the Notes or any Subsidiary Guarantee, as the case may be, such obligor shall pay, as additional
interest, to each Holder of Notes that are outstanding on the date of the required payment, such additional amounts (“Additional
Amounts”) as may be necessary so that the net amount received by such Holder (including the Additional Amounts) after such
withholding or deduction (including withholdings and deductions on Additional Amounts) shall not be less than the amount such Holder
would have received if such Taxes had not been withheld or deducted; provided that no Additional Amounts shall be payable with
respect to a payment made to a Holder or beneficial owner of the Notes (an “Excluded Holder”):

 

(1)         which
is subject to such Taxes by reason that it does not deal at arm’s length (within the meaning of the Income Tax Act (Canada))
with the applicable obligor at the time of making such payment;

 

(2)         which
is subject to such Taxes by reason of its being or having been connected with Canada or a province thereof otherwise than by the
mere holding or ownership, or deemed holding or ownership of the Notes or the receipt of payments thereunder or under any Subsidiary
Guarantee (as a matter of, for example, citizenship, nationality, residence, domicile, or existence of a business or permanent
establishment, a dependent agent, a place of business or a place of management present or deemed present within the Taxing Authority);

 

(3)         which
is subject to such Taxes by reason of the fact that it is a specified shareholder of the obligor for the purposes of subsection
18(5) of the Income Tax Act (Canada), or a person that does not deal at arm’s length with any such specified shareholder;

 

(4)         where
such Taxes are on account of any tax, duty, assessment or other charge imposed pursuant to Sections 1471 through 1474 of the Code,
any current for future regulations or official interpretations thereof, any similar law or regulation adopted pursuant to an intergovernmental
agreement between a non-U.S. jurisdiction and the United States, with respect to the forgoing or any agreements entered into pursuant
to Section 1471(b)(1) of the Code;

 

    	86

    	 

    

 

(5)         which
failed to duly and timely comply with a timely request of the Company to provide information, documents or other evidence concerning
such Holder’s or beneficial owner’s nationality, residence, entitlement to treaty benefits or identity, if and to the
extent that (A) such Holder and/or beneficial owner was legally able to comply with such request and (B) due and timely compliance
with such request is required by applicable law or administrative policy as a precondition to reduction or elimination of, and
would have reduced or eliminated, any Taxes as to which Additional Amounts would have otherwise been payable to such Holder or
beneficial owner but for this clause;

 

(6)         which
is a fiduciary or a partnership or not the sole beneficial owner of the relevant Note, if and to the extent that any beneficiary
or settlor with respect to such fiduciary, any partner with respect to such partnership or any beneficial owner of such Note (as
the case may be) would not have been entitled to receive Additional Amounts with respect to the payment in question had such beneficiary,
settlor, partner or beneficial owner been the actual Holder of such Note;

 

(7)         in
respect of any estate, gift, inheritance, value added, excise, transfer, intangible or similar tax; or

 

(8)         any
combination of the above clauses in this proviso.

 

(c)          The
applicable obligor on the Notes or any Subsidiary Guarantee, as the case may be, shall make any required withholding or deduction
and remit the full amount deducted or withheld to the Taxing Authority in accordance with applicable law. The applicable obligor
on the Notes or any Subsidiary Guarantee, as the case may be, shall provide to the Holders of the Notes, within 30 days after the
date the payment of any Taxes so deducted or withheld are due pursuant to applicable law, a copy of such tax receipts evidencing
such payment, if any, that provides reasonable evidence of such payment by such obligor.

 

(d)          In
addition, the applicable obligor on the Notes or any Subsidiary Guarantee, as the case may be, shall indemnify and hold harmless
each Holder or beneficial owner (without duplication) of Notes that are outstanding on the date of the required payment and upon
written request reimburse each such Holder or beneficial owner for the amount of: (i) any Taxes so levied or imposed by a Taxing
Authority and paid by such Holder or beneficial owner (without duplication) as a result of payments made under or with respect
to the Notes or any Subsidiary Guarantee, but excluding any such Taxes with respect to which such Holder or beneficial owner is
an Excluded Holder, and (ii) any such Taxes imposed on such Holder or beneficial owner (other than any such Taxes with respect
to which such Holder or beneficial owner is an Excluded Holder) with respect to any reimbursement under clause (i) immediately
above (collectively, “Reimbursement Payments”).

 

(e)          At
least 30 days prior to each date on which any payment under or with respect to any Note is due and payable, if the Company becomes
obligated to pay Additional Amounts with respect to such payment, the Company shall deliver to the Trustee an Officers’ Certificate
stating the fact that such Additional Amounts shall be payable and the amounts so payable and shall set forth such other information
necessary to enable the Trustee to pay such Additional Amounts to holders of Notes on the payment date.

 

    	87

    	 

    

 

(f)          Whenever
in this Indenture there is mentioned, in any context, the payment of principal (and premium, if any), purchase prices in connection
with a repurchase or redemption of Notes, interest or any other amount payable on or with respect to any of the Notes, this Indenture
or the Subsidiary Guarantees, such mention shall be deemed to include mention of the payment of Additional Amounts and Reimbursement
Amounts provided for in this Section 4.17 to the extent that, in such context, Additional Amounts or Reimbursement Payments are,
were or would be payable in respect thereof.

after giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the Successor Company or any
Subsidiary of the Successor Company as a result of such transaction as having been Incurred by the Successor Company or such Subsidiary
at the time of such transaction), no Default or Event of Default shall have occurred and be continuing;

 

(3)         either
(A) immediately after giving effect to such transaction, the Successor Company would be able to Incur at least an additional
$1.00 of Indebtedness pursuant to Section 4.07(a), or (B) immediately after giving effect to such transaction on a pro forma
basis and any related financing transactions as if the same had occurred at the beginning of the applicable four quarter period,
the Consolidated Coverage Ratio of the Company is equal to or greater than the Consolidated Coverage Ratio of the Company immediately

(4)         if
the Company is not the Successor Company, each Subsidiary Guarantor (unless it is the other party to the transactions above, in
which case Section 5.01(a)(1) above shall apply) shall have by supplemental indenture confirmed that its Subsidiary Guarantee
shall apply to such Person’s obligations in respect of this Indenture and the Notes shall continue to be in effect; and

 

    	88

    	 

    

 

(5)         the
Company shall have delivered, or caused to be delivered, to the Trustee an Officers’ Certificate and an Opinion of Counsel,
each stating that such consolidation, merger, conveyance, transfer or lease and such supplemental indenture (if any) comply with
this Indenture.

 

For purposes of this Section 5.01, the
sale, lease, conveyance, assignment, transfer or other disposition of all or substantially all of the properties and assets of
one or more Subsidiaries of the Company, which properties and assets, if held by the Company instead of such Subsidiaries, would
constitute all or substantially all of the properties and assets of the Company on a consolidated basis, shall be deemed to be
the transfer of all or substantially all of the assets of the Company.

 

(b)          The
Company shall not permit any Subsidiary Guarantor to consolidate with or merge with or into, and will not permit the conveyance,

its Subsidiary Guarantee after and upon compliance with Section 10.04.

 

(c)          Notwithstanding
Section 5.01(a)(3), (x) any Restricted Subsidiary may consolidate with, merge into or transfer all or part of its properties

the Company in another jurisdiction; and provided further that, in the case of a Restricted Subsidiary that consolidates
with, merges into or transfers all or part of its properties and assets to the Company, the Company will not be required to comply
with Section 5.01(a)(5).

 

(d)          Upon
any consolidation of the Company with, or merger of the Company into, any other Person or any conveyance, transfer or lease of
all or substantially all of the assets of the Company in accordance with Section 5.01(a), the Successor Company shall succeed to,
and be substituted for, and may exercise every right and power of, the Company, under this Indenture with the same effect as if
such successor Person has been named as the Company herein, and thereafter, except in the case of a lease, the predecessor Person
shall be released from the obligation to pay the principal of and interests on the Notes and all other covenants and obligations
under this Indenture.

whether such Indebtedness or Guarantee now exists, or is created after the date of this Indenture, which default: (1) is caused
by a failure to pay principal of, or interest or premium, if any, on such Indebtedness prior to the expiration of the grace period
provided in such Indebtedness (and any extensions of any grace period) (a “payment default”) or (2) results
in the acceleration of such Indebtedness prior to its Stated Maturity and, in each case, the principal amount of any such Indebtedness,

Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary in an involuntary case;

insurer as to which the insurer has not disclaimed coverage), which judgments are not paid or discharged, and there shall be any
period of 60 consecutive days following entry of such final judgment or decree during which a stay of enforcement of such final

Notwithstanding the
foregoing, if an Event of Default specified in Section 6.01(f) above shall have occurred and be continuing, such Event of Default
and any consequential acceleration (to the extent not in violation of any applicable law or in conflict with any judgment or decree
of a court of competent jurisdiction) shall be automatically rescinded if (i) the Indebtedness that is the subject of such
Event of Default has been repaid, or (ii) if the default relating to such Indebtedness is waived by the holders of such Indebtedness
or cured and if such Indebtedness has been accelerated, then the holders thereof have rescinded their declaration of acceleration
in respect of such Indebtedness, in each case within 30 days after the declaration of acceleration with respect thereto.

 

Section
6.02         Acceleration.

 

(a)          If
an Event of Default (other than as specified in Sections 6.01(g) or (h)) shall occur and be continuing with respect to this Indenture,
the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes then outstanding may, and the Trustee
at the request of such Holders shall, declare all unpaid principal of, premium, if any, and accrued interest on all Notes to be
due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders of the Notes) and
upon any such declaration, such principal, premium, if any, and interest shall become due and payable immediately. If an Event
of Default specified in Sections 6.01(g) or (h) occurs and is continuing, the principal of, premium, if any, accrued and unpaid
interest, if any, on all the Notes will become and be immediately due and payable without any declaration or other act on the part
of the Trustee or any Holders.

 

    	92

    	 

    

 

(b)          After
a declaration of acceleration, the Holders of a majority in aggregate principal amount of Notes outstanding by notice to the Company
and the Trustee, on behalf of the Holders of Notes, may rescind and annul such declaration and its consequences if:

 

(1)         the
Company has paid or deposited with the Trustee a sum sufficient to pay (A) all sums paid or advanced by the Trustee under
this Indenture and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, (B) all
overdue interest on all Notes then outstanding, and (C) the principal of, and premium, if any, on any Notes then outstanding
which have become due otherwise than by such declaration of acceleration and interest thereon at the rate borne by the Notes;

 

(2)         the
rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and

 

(3)         all
Events of Default, other than the non-payment of principal of, premium, if any, and interest on the Notes which have become due
solely by such declaration of acceleration, have been cured or waived as provided in this Indenture.

 

(c)          No
such rescission shall affect any subsequent default or impair any right consequent thereon.

 

Section
6.03         Other Remedies.

 

(a)          If
an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal,
premium, if any, or interest on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

 

(b)          The
Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Holder of a Note in exercising any right or remedy accruing upon and during the continuance
of an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default.
All remedies are cumulative to the extent permitted by law.

 

Section
6.04         Waiver of Past Defaults.

 

The Holders of not
less than a majority in aggregate principal amount of the Notes outstanding, by written notice to the Trustee and the Company,
may on behalf of the Holders of all outstanding Notes waive any existing Default or Event of Default under this Indenture and its
consequences, except a continuing Default or Event of Default (1) in the payment of the principal of, premium, if any, or
interest on any Note (which may only be waived with the consent of each Holder of Notes affected), or (2) in respect of a
covenant or provision which under this Indenture cannot be modified or amended without the consent of the Holder of each Note affected
by such modification or amendment.  In case of any such waiver, the Company, the Trustee and the Holders shall be restored
to their former positions and rights hereunder and under the Notes, respectively. This Section 6.04 shall be in lieu of Section 316(a)(1)(B) of
the TIA and such Section 316(a)(1)(B) of the TIA is hereby expressly excluded from this Indenture and the Notes, as permitted
by the TIA. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed
to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair
any right consequent thereon.

 

    	93

    	 

    

 

Section
6.05         Control by Majority.

 

Holders of a majority
in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse
to follow any direction that conflicts with law or this Indenture or that the Trustee determines is unduly prejudicial to the rights
of other Holders of Notes or that would involve the Trustee in personal liability.

 

Section
6.06         Limitation on Suits.

 

Subject to Section
6.07 and Section 7.01, no Holder of any of the Notes has any right to institute any proceedings with respect to this Indenture
or any remedy thereunder, unless (1) such Holder has previously given the Trustee written notice that an Event of Default
has occurred and is continuing, (2) the Holders of at least 25% in aggregate principal amount of the outstanding Notes have
made written request to the Trustee to institute a proceeding or pursue a remedy, (3) such Holders have furnished reasonable
security or indemnity to the Trustee to institute such proceeding or pursue such remedy as Trustee under the Notes and this Indenture,
(4) the Trustee has failed to institute such proceeding or pursue such remedy within 60 days after receipt of such notice
and such offer of security or indemnity, and (5) the Holders of a majority in aggregate principal amount of the outstanding
Notes have not waived such Event of Default or otherwise given the Trustee a direction that, in the opinion of the Trustee, is
inconsistent with such request within such 60-day period.

 

Section
6.07         Rights of Holders of Notes to Receive Payment.

 

Notwithstanding any
other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, premium, if any, or interest
on such Note, on or after the respective due dates expressed in such Note (including in connection with an offer to purchase),
or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without
the consent of such Holder.

 

Section
6.08         Collection Suit by Trustee.

 

If an Event of Default
specified in Section 6.01(a) or (b) above occurs and is continuing, the Trustee is authorized to recover judgment in its own name
and as trustee of an express trust against the Company for the whole amount of overdue principal of, premium, if any, interest
remaining unpaid on the Notes and to the extent lawful, interest on overdue principal, premium, if any, and interest and such further
amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel.

 

    	94

    	 

    

 

Section
6.09         Trustee May File Proofs of Claim.

 

The Trustee is authorized
to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and
counsel) and the Holders of the Notes allowed in any judicial proceedings relative to the Company or any Subsidiary Guarantor (or
any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute
any money or other securities or property payable or deliverable on any such claims and any custodian in any such judicial proceeding
is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the
making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.07. To
the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 7.07 out of the estate in any such proceeding, shall be denied for any reason,
payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities
and other properties that the Holders may be entitled to receive in such proceeding whether in liquidation or under any plan of
reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent
to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the
Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

 

Section

incurred, and all advances made, by the Trustee and the costs and expenses of collection;

 

Second: to Holders
of Notes for amounts due and unpaid on the Notes for principal, premium, if any, interest ratably, without preference or priority
of any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively;
and

 

Third: to the
Company or to such party as a court of competent jurisdiction shall direct.

 

(b)          The
Trustee may fix a record date and payment date for any payment to Holders of Notes pursuant to this Section 6.10.

 

    	95

    	 

    

 

Section
6.11         Undertaking for Costs.

 

In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it
as a Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs
of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees and expenses,
against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07, or

Section
7.01         Duties of Trustee.

 

(a)          In
the event an Event of Default has occurred and is continuing, the Trustee shall exercise such of the powers to use the degree of
care in its exercise, as a prudent person would use in the conduct of his own affairs.

 

(b)          Except
during the continuance of an Event of Default:

 

(1)         the
duties of the Trustee shall be determined solely by the express provisions of this Indenture and the Trustee need perform only
those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be
read into this Indenture against the Trustee; and

 

(2)         in
the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness
of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of
this Indenture. However, the Trustee shall examine the certificates and opinions to determine whether or not they conform on their
face to the requirements of this Indenture.

 

(c)          The
Trustee may not be relieved from liabilities for its own negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

 

(1)         this
paragraph does not limit the effect of paragraph (b) of this Section 7.01;

 

(2)         the
Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the

or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs

    	96

    	 

    

 

(e)          No
provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee shall
be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any
of the Holders unless such Holders shall have furnished to the Trustee security or indemnity reasonably satisfactory to it against
the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction.

held in trust by the Trustee need not be segregated from other funds and need not be held in an interest-bearing account, in each

shall not be liable for interest on any money received by it hereunder unless the Trustee otherwise agrees in writing with the
Company.

(b)          Before
the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion of Counsel or both. The Trustee

otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company shall be sufficient
if signed by an Officer of the Company.

 

(f)          The
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction
of any of the Holders unless such Holders shall have furnished to the Trustee security or indemnity reasonably satisfactory to

event shall the Trustee be liable to any Person for special, punitive, indirect, consequential or incidental loss or damage of
any kind whatsoever (including, but not limited to, lost profits) for any action it takes or omits to take, even if the Trustee
has been advised of the likelihood of such loss or damage.

 

    	97

    	 

    

 

(g)          The

references the Notes.

 

(h)          Subject
to Section 7.01(b)(2), the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution,
certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence
of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation
into such facts or matters as it may see fit.

 

(i)          The
rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified,
are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent, custodian and
other Person employed to act hereunder.

 

Section
7.03         Individual Rights of Trustee.

 

The Trustee in its
individual or any other capacity may become the owner or pledgee of Notes and may become a creditor of, or otherwise deal with,
the Company or any of its Affiliates with the same rights it would have if it were not Trustee. However, in the event that the
Trustee acquires any conflicting interest as described in the TIA while any Default exists, it must eliminate such conflict within
90 days, apply to the SEC for permission to continue as Trustee with such conflict or resign as Trustee. Any Agent may do the same
with like rights and duties. The Trustee is also subject to Sections 7.10 and 7.11.

 

Section

(a)          Within
60 days after each May 15, beginning with May 15, 2015, and for so long as Notes remain outstanding, the Trustee shall mail to
the Holders of the Notes a brief report dated as of such reporting date that complies with TIA Section 313(a) (but if
no event described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report

Section
7.07         Compensation and Indemnity.

 

(a)          The
Company shall pay to the Trustee (in its capacity as Trustee, and, to the extent it has been appointed as such, as Paying Agent
and Registrar) from time to time reasonable compensation for its acceptance of this Indenture and services hereunder in accordance
with a written schedule provided by the Trustee to the Company. The Trustee’s compensation shall not be limited by any law
on compensation of a trustee of an express trust. The Company shall reimburse the Trustee promptly upon request for all reasonable
disbursements, advances and reasonable out-of-pocket expenses incurred or made by it in addition to the compensation for its services,
except those resulting from its own negligent action, negligent failure to act or willful misconduct. Such expenses shall include
the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

 

(b)          The
Company shall indemnify the Trustee in its capacity against any and all losses, liabilities or reasonable out-of-pocket expenses
incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including
the costs and expenses of enforcing this Indenture against the Company (including this Section 7.07) and defending itself against
any claim (whether asserted by either of the Company or any Holder or any other person) or liability in connection with the exercise
or performance of any of its powers or duties hereunder, except to the extent any such loss, liability or expense may be attributable
to its negligence or bad faith. The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure
by the Trustee to so notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the
claim and the Trustee shall cooperate in the defense. The Trustee may elect to have separate counsel defend the claim, but the
Company will be obligated to pay the reasonable fees and expenses of such separate counsel only if the Company fails to assume
the Trustee’s defense or there is a conflict of interest between the Company, on the one hand, and the Trustee, on the other
hand, with respect to the claim, as reasonably determined by the Trustee. The Company need not pay for any settlement made without
its consent, which consent shall not be unreasonably withheld or delayed.

or property held or collected by the Trustee, except that held in trust to pay principal, premium, if any, and interest on particular
Notes. Such Lien shall survive the satisfaction and discharge of this Indenture and the resignation or removal of the Trustee.

 

(e)          When
the Trustee incurs expenses or renders services after an Event of Default specified in Sections 6.01(g) or (h) occurs, the expenses
and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses
of administration under any Bankruptcy Law.

Article
VIII

DEFEASANCE AND COVENANT DEFEASANCE

 

Section
8.01         Option to Effect Legal Defeasance or Covenant Defeasance.

 

The Company may, at
its option and at any time, elect to have either Section 8.02 or 8.03 be applied to all outstanding Notes upon compliance with
the conditions set forth below in this Article VIII.

 

    	101

    	 

    

 

Section
8.02         Legal Defeasance and Discharge.

 

Upon the Company’s
exercise under Section 8.01 of the option applicable to this Section 8.02, the Company shall, subject to the satisfaction of the
conditions set forth in Section 8.04, be deemed to have been discharged from its obligations with respect to this Indenture and
all outstanding Notes and all obligations of the Subsidiary Guarantors shall be deemed to have been discharged with respect to
their obligations under this Indenture and the Guarantees on the date the conditions set forth below are satisfied (hereinafter,
“Legal Defeasance”). For this purpose, Legal Defeasance means that the Company and the Subsidiary Guarantors shall
be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes and Guarantees, respectively,
which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 and the other Sections of
this Indenture referred to in clauses (a) and (b) of this Section 8.02, and shall be deemed discharged from the payment and performance
of all other obligations under this Indenture, the Notes and the Guarantees (and the Trustee, on demand of and at the expense of
the Company, shall execute proper instruments acknowledging the same), except for the following provisions which shall survive
until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive solely from
Funds in Trust (as defined in Section 8.04 and as more fully set forth in such Section) payments in respect of the principal of,
premium, if any, and interest on such Notes when such payments are due, (b) subject to clause (a) of this Section 8.02, the
Company’s obligations with respect to such Notes under Article II and Section 4.02, (c) the rights, powers, trusts,
duties and immunities of the Trustee hereunder, (d) this Article VIII and (e) Section 3.11. Subject to compliance with this
Article VIII, the Company may exercise its option under this Section 8.02 notwithstanding the prior exercise of its option under
Section 8.03.  If the Company exercises its legal defeasance option pursuant to this Section 8.02, the Subsidiary Guarantees
will terminate with respect to the Notes, and payment of the Notes may not be accelerated pursuant to Section 6.02 because of an
Event of Default with respect to the Notes.  Subject to compliance with this Article VIII, the Company may exercise its option
(if any) to have this Section 8.02 applied to any Notes notwithstanding the prior exercise of its option (if any) to have Section
8.03 applied to such Notes.

 

Section
8.03         Covenant Defeasance.

 

Upon the Company’s
exercise under Section 8.01 of the option applicable to this Section 8.03, the Company shall, subject to the satisfaction of the
conditions set forth in Section 8.04, be released from its obligations, and each Restricted Subsidiary shall be released from its
obligations, under the covenants contained in Sections 4.07 through 4.15 and the limitations set forth in Section 5.01(a)(3) with
respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 are satisfied (hereinafter, “Covenant
Defeasance”), and the Notes shall thereafter be deemed not “outstanding” for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall
continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such Notes shall not
be deemed outstanding for accounting purposes to the extent permitted by GAAP). For this purpose, Covenant Defeasance means that,
with respect to the outstanding Notes, the Company and each Restricted Subsidiary may omit to comply with and shall have no liability
in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein
or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 6.01,
but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the
Company’s exercise under Section 8.01 of the option applicable to this Section 8.03, subject to the satisfaction of the conditions
set forth in Section 8.04, (i) Sections 6.01(f), (g) and (h) (clauses (g) and (h) with respect to Significant Subsidiaries
only), and Sections 6.01(i) and (j) shall not constitute Events of Default, (ii) payment of the Notes may not be accelerated
because of an Event of Default specified in Sections 6.01(d), (e), (f), (g) or (h) (clauses (g) and (h) with respect to Significant
Subsidiaries only), or Sections 6.01(i) and (j) or because of the failure of the Company to comply with Section 5.01(a)(3), and
(iii) the Subsidiary Guarantees will terminate with respect to the Notes.

in the applicable U.S. federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall
confirm that, the Holders and Beneficial Owners of the outstanding Notes will not recognize income, gain or loss for U.S. federal
income tax purposes or Canadian federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal
income tax or Canadian federal income tax on the same amounts, in the same manner and at the same times as would have been the
case if such Legal Defeasance had not occurred;

 

(c)          in
the case of Covenant Defeasance, the Company shall have delivered to the Trustee one or more opinions of independent counsel in
the United States and Canada reasonably acceptable to the Trustee confirming that the Holders and Beneficial Owners of the outstanding

which will be applied to such deposit);

 

(e)          such
deposit shall not result in a breach of, or constitute a default under, any material agreement or instrument (other than this Indenture)
to which the Company, any Subsidiary Guarantor or any Restricted Subsidiary is a party or by which it is bound or if such breach
or default would occur, which is not waived as of, or for all purposes, on or after, the date of such deposit;

 

    	103

    	 

    

 

(f)          the
Company shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by the Company
with the intent of preferring the Holders of the Notes or any Guarantee over the other creditors of the Company or any Subsidiary
Guarantor with the intent of defeating, hindering, delaying or defrauding creditors of the Company, any Subsidiary Guarantor or
others; and

 

(g)          the
Company will have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions

to Be Held in Trust; Other Miscellaneous Provisions.

 

(a)          Subject
to Section 8.06, all money and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04
in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such
Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent)
as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium
and interest, but such money need not be segregated from other funds except to the extent required by law.

 

(b)          The
Company shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or U.S.
Government Obligations deposited pursuant to Section 8.04 or the principal and interest received in respect thereof other than
any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

 

(c)          Anything
in this Article VIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon the
request of the Company any money or U.S. Government Obligations held by it as provided in Section 8.04 which, in the opinion of
a nationally recognized firm of independent public accountants, investment bank, or appraisal firm expressed in a written certification
thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(a)), are in excess of the amount thereof
that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

 

Section
8.06         Repayment to the Company.

 

Any money deposited
with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any,
or interest on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become
due and payable shall be paid to the Company upon its request or (if then held by the Company) shall be discharged from such trust;

such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease;
provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, shall
at the expense of the Company comply with the SEC Regulation 17AD-17 as it applies to lost bondholders.

 

    	104

If the Trustee or Paying
Agent is unable to apply any United States dollars or U.S. Government Obligations in accordance with Section 8.02 or 8.03, as the
case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company’s obligations to make the related payments under this Indenture and the Notes shall be
revived and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 until such time as the Trustee or Paying
Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03, as the case may be; provided, however,
that, if the Company make any payment of principal of, premium, if any, or interest on any Note following the reinstatement of
its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money
held by the Trustee or Paying Agent.

    	107

    	 

    

 

Section
9.04         Revocation and Effect of Consents.

 

Until an amendment,
supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and

Article

SUBSIDIARY GUARANTEES

 

Section
10.01         Subsidiary Guarantee.

 

(a)          As
of the Issue Date, the Notes will not be guaranteed by any of the Company’s Subsidiaries. The following provisions of this
Article X shall apply to any Restricted Subsidiary that becomes a Subsidiary Guarantor after the Issue Date. Subject to this Article
X, each of the Subsidiary Guarantors, jointly and severally, fully and unconditionally, guarantees, on a senior unsecured basis,
to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective
of the validity and enforceability of this Indenture, the Notes or the obligations of the Company hereunder or thereunder, that:
(i) the principal of, premium, if any, and interest on the Notes will be promptly paid in full when due, whether at Stated
Maturity, by acceleration, redemption or otherwise, and interest on the overdue principal of, premium, if any, and interest on
the Notes, if any, if lawful (subject in all cases to any applicable grace period provided herein), and all other monetary Obligations
of the Company to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance
with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or any of
such other Obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension
or renewal, whether at stated maturity, by acceleration or otherwise. Failing payment when due of any amount so guaranteed or any
performance so guaranteed for whatever reason, the Subsidiary Guarantors shall be jointly and severally obligated to pay the same
immediately. Each Subsidiary Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

 

    	108

    	 

    

 

(b)          The
Subsidiary Guarantors agree that, to the maximum extent permitted under applicable law, their obligations hereunder shall be unconditional,
irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce
the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any
judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal
or equitable discharge or defense of a Subsidiary Guarantor. Subject to Section 6.06, each Subsidiary Guarantor waives diligence,
presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right
to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenant that this Guarantee
shall not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

 

(c)          If
any Holder or the Trustee is required by any court or otherwise to return to the Company, the Subsidiary Guarantors or any custodian,
trustee, liquidator or other similar official acting in relation to either of the Company or the Subsidiary Guarantors, any amount
paid by either to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect.

 

(d)          Each
Subsidiary Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of
any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Subsidiary Guarantor further
agrees that, as between the Subsidiary Guarantors, on the one hand, and the Holders and the Trustee, on the other hand, (x) the
maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of this Guarantee,
notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed
hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article VI, such obligations
(whether or not due and payable) shall forthwith become due and payable by the Subsidiary Guarantors for the purpose of this Guarantee.
Each Subsidiary Guarantor that makes a payment or distribution under its Guarantee shall have the right to seek contribution from
any non-paying Subsidiary Guarantor, in a pro rata amount based on the net assets of each Subsidiary Guarantor determined in accordance
with GAAP, so long as the exercise of such right does not impair the rights of the Holders under the Guarantee.

 

(e)          In
respect to its obligations under its Guarantee, each Subsidiary Guarantor agrees to be bound to, and hereby covenants, with respect
to itself, the covenant set forth in Section 4.06.

 

    	109

    	 

    

 

Section
10.02         Limitation on Subsidiary Guarantor Liability.

 

Each Subsidiary Guarantor,
and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of
such Subsidiary Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent
Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee.
To effectuate the foregoing intention, the Trustee, the Holders and the Subsidiary Guarantors hereby irrevocably agree that the
obligations of such Subsidiary Guarantor will be limited to the maximum amount which, after giving effect to all other contingent
and fixed liabilities of such Subsidiary Guarantor, and after giving effect to any collections from or payments made by or on behalf
of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Guarantee or pursuant
to its contribution obligations under this Article X, will result in the obligations of such Subsidiary Guarantor under its Guarantee
not constituting a fraudulent conveyance or fraudulent transfer under federal or state law. Until such time as the Notes are paid
in full, each Subsidiary Guarantor waives all rights of subrogation or contribution, whether arising by contract or operation of
law (including, without limitation, any such right arising under federal Bankruptcy Law) or otherwise by reason of any payment
by it pursuant to the provisions of this Article X. Each Subsidiary Guarantor that makes a payment or distribution under its Guarantee
will be entitled to a contribution from each other Subsidiary Guarantor in a pro rata amount based on the net assets of each Subsidiary
Guarantor determined in accordance with GAAP.

 

Section
10.03         Execution and Delivery of Notation of Guarantee.

 

(a)          To
evidence its Guarantee set forth in Section 10.01, a Subsidiary Guarantor shall execute a supplemental indenture to this Indenture
substantially in the form included in Exhibit E hereto and a notation of such Guarantee substantially in the form included in Exhibit D
hereto endorsed by an Officer of such Subsidiary Guarantor by manual or facsimile signature on each Note authenticated and delivered
by the Trustee.

 

(b)          Each
Subsidiary Guarantor hereby agrees that its Guarantee set forth in Section 10.01 shall remain in full force and effect notwithstanding
any failure to endorse on each Note a notation of such Guarantee.

 

(c)          If
an Officer whose signature is on this Indenture or on the notation of Guarantee no longer holds that office at the time the Trustee
authenticates the Note on which a notation of Guarantee is endorsed, the Guarantee shall be valid nevertheless.

 

(d)          The
delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantee
set forth in this Indenture on behalf of the Subsidiary Guarantors.

 

Section
10.04         Releases of Subsidiary Guarantors.

 

(a)          If
no Default or Event of Default has occurred and is continuing, a Subsidiary Guarantor will be deemed automatically and unconditionally
released and discharged from all of its obligations under its Guarantee without any further action on the part of the Trustee or
any Holder of the Notes:

 

    	110

    	 

    

 

(1)         in
connection with any sale or other disposition of (i) all of the Capital Stock of such Subsidiary Guarantor or (ii) all or substantially
all of the properties or assets of such Subsidiary Guarantor (including by way of merger or consolidation), in each case to one
or more Persons that are not (either before or after giving effect to such transaction) the Company or a Restricted Subsidiary,
if the sale or other disposition, as applicable, does not violate Section 4.11;

 

(2)         if
such Subsidiary Guarantor is a Restricted Subsidiary, the Company properly designates such Subsidiary Guarantor as an Unrestricted
Subsidiary or the Subsidiary no longer meets the definition of Restricted Subsidiary;

 

(3)         if
the Guarantee was required pursuant to the terms of Section 4.13, the release or discharge of the guarantee that required such
Guarantee (except a release or discharge by or as a result of payment under such Guarantee);

 

(4)         upon
a satisfaction and discharge or a legal or covenant defeasance of the Notes in accordance with Article VIII or Article XI; or

 

(5)         upon
the liquidation or dissolution of such Subsidiary Guarantor.

 

(b)          Any
Subsidiary Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal
of, premium, if any, and interest on the Notes and for the other obligations of any Subsidiary Guarantor under this Indenture as
provided in this Article X.

(a)          either:

 

(1)         all
such Notes theretofore authenticated (except lost, stolen or destroyed Notes which have been replaced or paid or Notes whose payment

(2)         all
Notes not theretofore delivered to the Trustee for cancellation have become due and payable or will become due and payable
at their Stated Maturity within one year by reason of the giving of a notice of redemption or otherwise;

 

    	111

    	 

    

 

(b)          the
Company or any Subsidiary Guarantor has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust
an amount in United States dollars, U.S. Government Obligations, or a combination thereof, sufficient, in the opinion of a nationally
recognized firm of independent public accountants or a nationally recognized investment banking firm, without consideration of

for cancellation, including principal of, premium, if any, and accrued interest at such Stated Maturity or redemption date;

Company or any Subsidiary Guarantor has paid or caused to be paid all other sums due and payable under this Indenture by the Company

to Be Held in Trust; Other Miscellaneous Provisions.

 

(a)          Subject
to Section 11.03, all money and non-callable U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee
(or other qualifying trustee, collectively for purposes of this Section 11.02, the “Trustee”) pursuant to Section 11.01
in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such
Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent)
as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium
and interest, but such money need not be segregated from other funds except to the extent required by law.

 

(b)          Notwithstanding
the above, the Trustee shall pay to the Company from time to time upon its request any cash or U.S. Government Obligations held
by it as provided in this Section 11.02 which, in the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification delivered to the Trustee, are in excess of the amount thereof that would then be required
to be deposited to effect a satisfaction and discharge under this Article XI.

 

Section
11.03       Repayment to the Company.

 

Any money deposited
with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, premium or interest
on any Note and remaining unclaimed for two years after such principal, and premium, if any, or interest has become due and payable
shall be paid to the Company on its request or (if then held by the Company) shall be discharged from such trust; and the Holder
of such Note shall thereafter look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent
with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however,
that the Trustee or such Paying Agent, before being required to make any such repayment, shall at the expense of the Company cause
to be published once in The New York Times or The Wall Street Journal (national edition) or send to each Holder entitled
to such money, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than

Section

If the Trustee or Paying
Agent is unable to apply any United States dollars or U.S. Government Obligations in accordance with Section 11.01, by reason of
any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application,
then the Company’s obligations to make the related payments under this Indenture and the Notes shall be revived and reinstated
as though no deposit had occurred pursuant to Section 11.01 until such time as the Trustee or Paying Agent is permitted to apply
all such money in accordance with Section 11.02 or 11.01; provided, however, that, if the Company make any payment
of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

Section
12.13         Counterpart Originals.

 

The parties may sign
any number of copies of this Indenture, and each party hereto may sign any number of separate copies of this Indenture. Each signed

Section
12.14         Acts of Holders.

 

(a)          Any
request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken
by the Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders
in person or by agents duly appointed in writing, and may be given or obtained in connection with a purchase of, or tender offer
or exchange offer for, outstanding Notes; and, except as herein otherwise expressly provided, such action shall become effective
when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act”
of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any
such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Company if made
in the manner provided in this Section 12.14.

 

(b)          The
fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying
that the individual signing such instrument or writing acknowledged to such witness, notary or officer the execution thereof. Where
such execution is by a signer acting in a capacity other than his or her individual capacity, such certificate or affidavit shall
also constitute sufficient proof of authority. The fact and date of the execution of any such instrument or writing, or the authority
of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

 

    	117

    	 

    

 

(c)          Notwithstanding
anything to the contrary contained in this Section 12.14, the principal amount and serial numbers of Notes held by any Holder,
and the date of holding the same, shall be proved by the register of the Notes maintained by the Registrar as provided in Section
2.04.

 

(d)          If
the Company shall solicit from the Holders of the Notes any request, demand, authorization, direction, notice, consent, waiver
or other Act, the Company may, at its option, fix in advance a record date for the determination of Holders entitled to give such
request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do
so. Notwithstanding TIA Section 316(c), such record date shall be a date not earlier than the date 30 days prior to the first
solicitation of Holders generally in connection therewith or the date of the most recent list of Holders forwarded to the Trustee
prior to such solicitation pursuant to Section 2.06 and not later than the date such solicitation is completed. If such a record
date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after
such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for
the purposes of determining whether Holders of the requisite proportion of the then outstanding Notes have authorized or agreed
or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the
then outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the

Capitalized terms used

1.          Interest.
The Company promises to pay interest on the unpaid principal amount of this Note at 6.125% per annum [and shall pay Additional
Interest, if any, as provided in the Registration Rights Agreement, dated September 18, 2014, referred to below]. The Company shall

Payment Date”); provided, that the first Interest Payment Date shall be April 1, 2015. Interest on the Notes shall
accrue from the most recent date to which interest has been paid on the Notes (or one or more Predecessor Notes) or, if no interest
has been paid, from and including the date of original issuance; provided, that if there is no existing Default in the payment
of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest
Payment Date, interest shall accrue from such next succeeding Interest Payment Date. The Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal and premium, if any, from time to time
on demand at the rate then in effect on the Notes to the extent lawful; it shall pay interest (including post-petition interest
in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace periods)
from time to time on demand at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year of
twelve 30-day months. If any payment date with respect to the Notes is not a Business Day, payment may be made on the next succeeding
day that is a Business Day, and no interest shall accrue on such payment for the intervening period. The Company shall pay Additional
Amounts or Reimbursement Payments with respect to payments on the Notes in the circumstances set forth in Section 4.17 of the Indenture.

 

2.          Method
of Payment. The Company shall pay interest on the Notes (except defaulted interest, if any) to the Persons in whose name this
Note (or one or more Predecessor Notes) is registered at the close of business on March 15 or September 15 immediately preceding
the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date,
except as provided in Section 2.13 of the Indenture with respect to defaulted interest. [The Company shall pay all Additional
Interest, if any, in the amounts set forth in the Registration Rights Agreement.] The Notes shall be payable as to principal, premium,
if any, and interest [(including Additional Interest, if any),] at the office or agency of the Company maintained for such purpose,
or, at the option of the Company, payment of interest [(including Additional Interest, if any),] may be made by check mailed to
the Holders at their addresses set forth in the register of Holders, and provided, that payment by wire transfer of immediately

may withhold from Holders of the Notes notice of any continuing Default or Event of Default (except a Default or Event of Default
relating to the payment of principal or interest) if it determines that withholding notice is in their interest. The Holders of
not less than a majority in aggregate principal amount of the Notes outstanding by notice to the Trustee may on behalf of the Holders
of all outstanding Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing

	Name:	 	 
	 	 	 
	Address:	 	 

 

	Taxpayer ID Number.:	 	 

 

The undersigned represents and warrants
to you that:

 

1.          We
are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the
Securities Act of 1933, as amended (the “Securities Act”)) purchasing for our own account or for the account of such
an institutional “accredited investor” at least $250,000 principal amount of the Securities, and we are acquiring the
Securities not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We
have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risk of our
investment in the Securities and we invest in or purchase securities similar to the Securities in the normal course of our business.
We and any accounts for which we are acting are each able to bear the economic risk of our or its investment.

 

    	Exhibit B2 - 1

    	 

    

 

2.          We
understand that the Securities have not been registered under the Securities Act and, unless so registered, may not be sold except
as permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing
Securities to offer, sell or otherwise transfer such Securities prior to the date that is one year after the later of the date
of original issue and the last date on which the Company or any affiliate of the Company was the owner of such Securities (or any
predecessor thereto) (the “Resale Restriction Termination Date”) only (a) to the Company, (b) pursuant to
a registration statement which has been declared effective under the Securities Act, (c) in a transaction complying with the
requirements of Rule 144A under the Securities Act, to a person we reasonably believe is a qualified institutional buyer under
Rule 144A (a “QIB”) that purchases for its own account or for the account of a QIB and to whom notice is given
that the transfer is being made in reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the United
States within the meaning of Regulation S under the Securities Act, (e) to an institutional “accredited investor”
within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act that is purchasing for its own account
or for the account of such an institutional “accredited investor,” in each case in a minimum principal amount of Securities
of $250,000 or (f) pursuant to any other available exemption from the registration requirements of the Securities Act, subject
in each of the foregoing cases to any requirement of law that the disposition of our property or the property of such investor
account or accounts be at all times within our or their control and in compliance with any applicable state securities laws. The
foregoing restrictions on resale will not apply subsequent to the Resale Restriction Termination Date. If any resale or other transfer
of the Securities is proposed to be made pursuant to clause (e) above prior to the Resale Restriction Termination Date, the
transferor shall deliver a letter from the transferee substantially in the form of this letter to the Company and the Trustee,
which shall provide, among other things, that the transferee is an institutional “accredited investor” (within the
meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act) and that it is acquiring such Securities for
investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that the Company and
the Trustee reserve the right prior to any offer, sale or other transfer prior to the Resale Termination Date of the Securities
pursuant to clauses (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications and/or other
information satisfactory to the Company and the Trustee.

 

This certificate and the statements contained
