(ii)    All leases and agreements necessary for the conduct of the business of the Issuer and its Subsidiaries are valid and subsisting, in full force and effect, except to the extent any failure to be valid and subsisting and in full force and effect could not reasonably be expected to have a Material Adverse Effect, and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a default under any such lease or agreement, which could reasonably be expected to have a Material Adverse Effect.

(iii)    The rights and properties presently owned, leased or licensed by the Issuer and its Subsidiaries including, without limitation, all easements and rights of way, include all rights and properties reasonably necessary to permit the Issuer and its Subsidiaries to conduct their business, except to the extent any failure to satisfy the foregoing could not reasonably be expected to have a Material Adverse Effect.

(m)     Marketing of Production . No material agreements exist which are not cancelable on sixty (60) days’ notice or less without penalty or detriment for the sale of production from the Issuer’s or any of its Subsidiaries’ Hydrocarbons (including, without limitation, calls on or other rights to purchase, production, whether or not the same are currently being exercised) that (a) pertain to the sale of production at a fixed price and (b) have a maturity or expiry date of more than six (6) months.

(ii)    any of the representations and warranties set forth in Section  3 of this Note shall be untrue or incorrect in any material respect as of the time made; or

(iii)        the Issuer shall fail to observe or perform the covenants contained in Section  8 or Section  14 of this Note and, in the case of Section  8 , such failure shall continue unremedied for a period of fifteen (15) days after an executive officer of the Issuer becomes aware of such failure;

(iv)    an Insolvency Event shall occur in respect of the Issuer; or

(v)    any event or condition occurs that results in any Material Debt becoming due prior to its scheduled maturity or that enables or permits (with or without the giving of notice, the lapse of time or both) the holder or holders of any Material Debt or any trustee or agent on its or their behalf to cause any Material Debt to become due, or to require the Redemption thereof or any offer to Redeem to be made in respect thereof, prior to its scheduled maturity or require the Issuer or any Subsidiary to make an offer in respect thereof; provided , however , that, any such event or condition described in this Section  4(a)(v) shall constitute an Event of Default under this Note if and only if fifteen (15) days have elapsed since the date an executive officer of the Issuer has become aware thereof and either (x) such event or condition has not been waived by the requisite holders of the applicable Material Debt or cured or (y) the applicable Material Debt has not been repaid, refinanced or replaced, in each case, during such fifteen (15) day period.

(b)     Remedies . Upon the occurrence of an Event of Default:

(i)    each Holder may declare all or any portion of its Holder Percentage of the unpaid Obligations under this Note to be immediately due and payable; provided , however , that if an Event of Default specified in Section  4(a)(iv) above occurs, the entire unpaid principal, accrued but unpaid interest and Obligations owing under this Note shall forthwith become and be immediately due and payable without any notice, declaration or other act on the part of any Holder; and

10

(ii)    each Holder shall be entitled to exercise any other rights which such Holder may have pursuant to Applicable Law.

Without limiting the generality of the foregoing, it is understood and agreed that if, prior to July 1, 2022, the amounts outstanding under this Note are accelerated or otherwise become due, in each case, in respect of any Event of Default (including, but not limited to, upon the occurrence of a bankruptcy or Insolvency Event (including the acceleration of claims by operation of law) (a “ Yield Maintenance Event ”)), the Applicable Premium or Prepayment Premium, respectively that would have applied if, at the time of such acceleration, the Issuer had paid, refinanced, substituted or replaced any or all of the Note as contemplated in Section  2(c) will also be due and payable as though a Yield Maintenance Event had occurred ( provided that any Interest Payments made in respect of the Note for any portion of the period from the date of acceleration through the date of such repayment shall be excluded in the calculation of the Applicable Premium or Prepayment Premium, as applicable) and the Applicable Premium or Prepayment Premium, as applicable, shall constitute part of the Obligations, in view of the impracticability and extreme difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable calculation of the Holders’ lost profits as a result thereof. Any Applicable Premium or Prepayment Premium, as applicable, payable above shall be presumed to be the liquidated damages sustained by the Holders as the result of payment or acceleration, as applicable, prior to July 1, 2022 and the Issuer agrees that the Applicable Premium and Prepayment Premium are reasonable under the circumstances currently existing.

THE ISSUER EXPRESSLY WAIVES (TO THE FULLEST EXTENT IT MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE FOREGOING APPLICABLE PREMIUM OR PREPAYMENT PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION.

The Issuer expressly agrees (to the fullest extent that it may lawfully do so) that: (1) the Applicable Premium and Prepayment Premium are reasonable and are the product of an arm’s length transaction between sophisticated business people, ably represented by counsel; (2) the Applicable Premium or Prepayment Premium, as applicable, shall be payable notwithstanding the then prevailing market rates at the time payment is made; (3) there has been a course of conduct between the Holders and the Issuer giving specific consideration in this transaction for such agreement to pay the Applicable Premium or Prepayment Premium, as applicable; and (4) the Issuer shall be estopped hereafter from claiming differently than as agreed to in this paragraph.

The Issuer expressly acknowledges that its agreement to pay the Applicable Premium or Prepayment Premium, as applicable, to the Holders as herein described is a material inducement to the Holders to purchase this Note.
