non-operator or operator, Mortgagor’s share of the estimated cost of the proposed operation prior to electing to participate in the operation. To the extent that Mortgagor is unable to consent to any proposed operation with respect to any of
the Mortgaged Property, prior to electing not to participate in the proposed operation, Mortgagor will use its best efforts, to the extent practicable once it is determined that it cannot so participate and to the extent allowed to do so under the
relevant operating agreement or other applicable contract, farmout to others acceptable to Mortgagee, on the best terms obtainable, which terms shall be acceptable to Mortgagee, the interest or relevant portion of the interest of Mortgagor in the

receipt of a request from Mortgagee, Mortgagor will furnish and deliver, a Title Opinion prepared by competent legal counsel covering title to the real property herein mortgaged from the Sovereignty of the Soil to the latest practicable date, when
taken together with abstracts and/or Title Opinions previously furnished to Mortgagee. Should Mortgagor fail to furnish such Title Opinion upon such request, Mortgagee may obtain such Title Opinion, and any and all costs incurred thereby shall be

 O. Notification of Legal Proceedings. Mortgagor will promptly notify Mortgagee or other holder or holders of the Indebtedness, in writing, of the
commencement of any legal proceedings affecting the Mortgaged Property or any part thereof, and will take such action as may be necessary to preserve its and Mortgagee’s rights affected thereby; and should Mortgagor fail or refuse to take any
such action, Mortgagee may at its election take such action on behalf and in the name of Mortgagor and at Mortgagor’s cost and expense. 
 P. Maintenance of Existence. If Mortgagor, is a corporation, it will maintain its corporate existence and will maintain and procure all necessary corporate franchise and permits to the end that Mortgagor shall be and continue to be a

shall have been fully satisfied.

otherwise, appropriate to enforce the conditions, covenants and terms of this Deed of Trust and of any note or guaranty reflecting the Indebtedness, and the employment of any remedy hereunder, or otherwise, shall not prevent the concurrent or
subsequent employment of any other appropriate remedy or remedies. 
 ARTICLE VI. 
 ASSIGNMENT OF PRODUCTION 
 A.
Assignment. In addition to the conveyance to the Trustee herein made, Mortgagor does hereby transfer, assign, deliver and convey unto Mortgagee, its successors and assigns, all of the oil, gas and other minerals produced, saved or sold from

purchaser now or hereafter taking any production from the Mortgaged Property to pay to Mortgagee such proceeds derived from the sale thereof, and to continue to make payments directly to Mortgagee until notified in writing by Mortgagee to
discontinue the same; and the purchaser of any such production shall not be required to see to the application of the proceeds thereof by Mortgagee and payment made to Mortgagee shall be binding and conclusive as between such purchaser and

revenues to paid to Mortgagee.

any liability on the part of Mortgagee in making such selection, so long as ordinary care is used in the making thereof; and failure of Mortgagor to consent to and promptly effect such change of connection shall constitute an event of default
hereunder, and the whole Indebtedness may be 

  

 DEED OF TRUST — Page 10 

 
immediately declared due and payable, at the option of Mortgagee and without demand, presentment or other notice (including, but not limited to notice of
intention to accelerate maturity and notice of acceleration of maturity), and the Mortgaged Property shall become subject to the foreclosure proceedings and power of sale hereunder. 
 C. Application of Proceeds. Mortgagor authorizes and empowers Mortgagee to receive, hold and collect all sums of money paid to Mortgagee in
accordance with this Assignment, and to apply the same as hereinafter provided, all without any liability or responsibility on the part of Mortgagee, save and except as to good faith in so receiving and applying such sums. All payments provided for
in this Assignment shall be paid promptly to Mortgagee, and any provisions contained in any note or notes evidencing the Indebtedness or any part thereof to the contrary notwithstanding, Mortgagee may apply the same or so much thereof as it elects
to the payment of the Indebtedness, application to be made in such manner as it may elect, regardless of whether the application so made shall exceed the payments of principal and interest then due as provided in the note or notes evidencing the
Indebtedness. After such application has been so made by Mortgagee, the balance of any such payment or payments remaining shall be paid to Mortgagor. 
 D. No Postponement of Installments on Indebtedness. It is understood and agreed that should such payments provided for by this Assignment be less than the sum or sums then due on the Indebtedness, such sum or
sums then due shall nevertheless be paid by Mortgagor in accordance with the provisions of the note, notes, guaranty agreements or other instrument or instruments evidencing the Indebtedness, and neither this Assignment nor any provisions hereof
shall in any manner be construed to affect the terms and provisions of such note, notes, guaranty agreements or other instrument or instruments evidencing the Indebtedness. Likewise, neither this Assignment nor any provisions hereof shall in any
manner be construed to affect the liens, rights, title and remedies herein granted under this Deed of Trust, and are cumulative of any other security which Mortgagee now holds or may hereafter hold to secure the payment of the Indebtedness.

sold from the Mortgaged Property, which under the terms hereof should have been remitted to Mortgagee, Mortgagor will immediately remit same in full to Mortgagee.

 ADDITIONAL REMEDIES 
 A.
Mortgagee’s Remedying of Mortgagor’s Failure to Comply. If Mortgagor should fail to comply with any of the covenants or obligations of Mortgagor hereunder, then Mortgagee or the Trustee may perform the same for the account and at
the expense of Mortgagor but shall not be obligated so to do, and any and all expenses incurred or paid in so doing shall be payable by Mortgagor to Mortgagee, with interest at the greater of (i) the rate of 10% per annum or (ii) the
rate agreed upon in any other document or instrument relating to the Indebtedness or any part thereof, from the date when same was so incurred or paid, and the amount thereof shall be payable on demand and shall be secured by and under this Deed of
Trust, and the amount and nature of such expense and the time when paid shall be fully established by the affidavit of Mortgagee or any officer or agent thereof, or by the affidavit of any Trustee acting hereunder; provided, however, that the
exercise of the privileges granted in this paragraph shall in nowise be considered or constitute a waiver of the right of Mortgagee upon the happening of an event of default hereunder to declare the Indebtedness at once due and payable but shall be
cumulative of such right and all other rights herein given.

default shall happen, then in each and every such cases the Trustee or Mortgagee or any holder of the Indebtedness or any part thereof, whether 

  

 DEED OF TRUST — Page 11 

 
or not the Indebtedness shall have been declared due and payable, in addition to the other rights and remedies hereunder, may exercise the following
additional remedy, but shall not be obligated so to do: the Trustee, Mortgagee or holder of the Indebtedness may enter into and upon and take possession of all or any part of the Mortgaged Property and each and every part thereof and may exclude
Mortgagor, its agents and servants wholly therefrom and have, hold, use, operate, manage and control the Mortgaged Property and each and every part thereof and produce the oil, gas and other minerals therefrom and market the same, all at the sole
risk and expense of Mortgagor and at the expense of the Mortgaged Property, applying the net proceeds to derived, first, to the cost of maintenance and operation of such Mortgaged Property; second, to the payment of all Indebtedness secured hereby,

Mortgagor in its then condition and such Trustee, Mortgagee or holder of the Indebtedness shall not be liable to Mortgagor for any damage or injury to the Mortgaged Property except such as may be caused through his, its or their fraud or willful
misconduct.

name, place and stead of Mortgagor in the exercise of each and every remedy set forth herein and in conducting any and all operations and taking any and all action reasonably necessary to do so, recognizing such agency in favor of Mortgagee to be
coupled with the interests of Mortgagee under this Deed of Trust, and, thus, irrevocable.

papers relating to the Indebtedness, seems to indicate any possibility of a different power given to the holder of the Indebtedness, or any authority to ask for, demand, or receive any larger rate of interest, such as a mistake in calculation or
wording, this clause shall override and control, and proper adjustments shall be made accordingly.

construction is appropriate, and specific enumeration shall not exclude the general, but shall be construed as cumulative. 
 D. Rights
and Remedies Cumulative. Every right and remedy provided for herein shall be cumulative of each and every other right or remedy of Mortgagee, whether herein or otherwise conferred, and may be enforced concurrently therewith, and the
unenforceability or invalidity of any one or more provisions, clauses, sentences or paragraphs of this instrument shall not render any other provision, clause, sentence or paragraph unenforceable or invalid. No security theretofore, herewith or
