Should a material adverse claim be made against or a cloud develop upon the title to any part of the Mortgaged Property, Mortgagor agrees it will immediately defend against such adverse claim or take appropriate action to remove such cloud at Mortgagor’s cost and expense, and Mortgagor further agrees that Mortgagee may take such other action as Mortgagee reasonably deems advisable to protect and preserve its interests in the Mortgaged Property, and in such event Mortgagor will indemnify Mortgagee against any and all costs, reasonable attorneys’ fees and other expenses which it may reasonably incur in defending against any such adverse claim or taking action to remove any such cloud.

ARTICLE V

DEFEASANCE, RESPECTING FORECLOSURE
AND OTHER REMEDIES

     5.1 Defeasance; Remedies. Should Mortgagor make payment in full of the Secured Indebtedness, then the conveyance of the Mortgaged Property shall become of no further force and effect, and the lien and security interest hereof shall be released at the cost and expense of Mortgagor; otherwise, it shall remain in full force and effect. In case any one or more of the Events of Default, as defined below, shall happen, then, and in any such event, the whole of the principal of the Secured Indebtedness due and remaining unpaid, together with all interest accrued thereon, may, at the option of the holder thereof, without notice (including, but not limited to, notice of intention to accelerate maturity and notice of acceleration of maturity) or demand, which are, to the full extent permitted by applicable law, waived by Mortgagor, be declared immediately due and payable; and thereupon, or at any time thereafter while the Secured Indebtedness or any part thereof remains unpaid, it shall be the duty of the Trustee, on request of the Mortgagee (which request is hereby presumed), to enforce this Deed of Trust; and after advertising the time and place of the sale for at least twenty-one (21) days prior to the day of sale, by posting or causing to be posted a written or printed notice thereof at the courthouse door and by filing a copy of such notice in the office of the county clerk or registrar of deeds, as applicable in each jurisdiction, of each county in which the Mortgaged Property or any part thereof may be situated, and serving written notice of the proposed sale on each debtor obligated to pay the Secured Indebtedness according to the records of the Mortgagee, by postage prepaid, certified United States mail, at the most recent address for such debtor as shown by the records

of the Mortgagee, at least twenty-one (21) days prior to the day of sale, to sell the Mortgaged Property, either as a whole or in parcels, as the Trustee may deem proper, at public venue at the courthouse of the county in which the Mortgaged Property or any part thereof may be situated (and being the county designated in the notice of sale) on the first Tuesday of any month between the hours of 10:00 o’clock a.m. and 4:00 o’clock p.m., to the highest bidder for cash, and after such sale to make the purchaser or purchasers good and sufficient deeds and assignments in the name of the Mortgagor herein, conveying such property so sold to the purchaser or purchasers with special warranty of title. The Trustee, or his successor or substitute, is hereby authorized and empowered to appoint any one or more persons as his attorney(s)-in-fact to act as Trustee under him and in his name, place and stead, such appointment to be evidenced by a written instrument executed by the Trustee, or his successor or substitute, to perform any one or more act or acts necessary or incident to any sale under the power of sale hereunder, including, without limitation, the posting and filing of any notices, the conduct of the sale and the execution and delivery of any instruments conveying the Mortgaged Property as a result of the sale, but in the name and on behalf of the Trustee, or his successor or substitute; and all acts done or performed by such attorney(s)-in-fact shall be valid, lawful and binding as if done or performed by the Trustee, or his successor or substitute. No single sale or series of sales by the Trustee shall extinguish the lien or exhaust the power of sale hereunder except with respect to the items of property sold, but such lien and power shall exist for so long as and may be exercised in any manner by law or as herein provided as often as the circumstances require to give Mortgagee full relief hereunder. The purchaser at any such sale shall not assume, nor shall his or its heirs, legal representatives, successors or assigns, be deemed to have assumed, by reason of the acquisition of property or rights mortgaged hereunder, any liability or obligation of any lessee or operator of the Mortgaged Property, or any part thereof, arising by reason of any occurrence taking place prior to such sale. It shall not be necessary to have present, or to exhibit at any such sale, any of the personal property subject to the lien or security interest hereof.

     5.2 Rights Under UCC. Upon the happening of any of the Events of Default, Mortgagee shall be entitled to all of the rights, powers and remedies afforded a secured party by the Uniform Commercial Code with reference to the personal property, As-extracted collateral and fixtures in which Mortgagee has been granted a security interest hereby, or Mortgagee may proceed as to both the real and personal property covered hereby.

     5.3 Application of Proceeds. The Trustee is authorized to receive the proceeds of said sale or sales and apply the same first to pay all reasonable expenses of any nature whatsoever incurred at any time (whether before or after an Event of Default) by Mortgagee in exercising or enforcing any rights, power and remedies provided in this Deed of Trust and next in reduction of the Secured Indebtedness, in such manner and order as Mortgagee may elect.

     5.4 Substitute Trustee. In the event of the dissolution of the Trustee (if an entity), or death of the Trustee (if an individual), or its removal from the State of Texas, or its or his/her failure, refusal, or inability for any reason to make any such sale or to perform any of the trusts herein declared, or at any time, whether with or without cause, then the Mortgagee may appoint, in writing, one or more substitute trustee who shall thereupon succeed to all the estates, rights, powers, and trusts herein granted to and vested in the Trustee. In the same events as first above stated, and in the same manner, successive substitute Trustees may thereafter be appointed.

     5.5 Evidence. It is agreed that in any deed or deeds given by any Trustee any and all statements of fact or other recitals therein made as to the identity of the holder or holders of the Secured Indebtedness, or as to the default in the payments thereof or any part thereof, or as to the breach of any covenants herein contained, or as to the request to sell, notice of sale, time, place, terms and manner of sale, and receipt, application, and distribution of the money realized therefrom, or as to the due and proper appointment of a substitute trustee, and, without being limited by the foregoing, as to any other additional act or thing having been done by Mortgagee or by the Trustee, shall be taken by all courts of law and equity as prima facie evidence that the statements or recitals state facts and are without further question to be so accepted; and Mortgagor does hereby ratify and confirm any and all acts that the Trustee may lawfully do in the premises by virtue of the terms and conditions of this Deed of Trust.

     5.6 Right to Sue. The Mortgagee may, at its election, or the Trustee may, upon written request of the Mortgagee, proceed by suit or suits, at law or in equity, to enforce the payment of the Secured Indebtedness in accordance with the terms hereof and of the note, notes or guaranties evidencing it, and to foreclose the lien and/or security interest of this Deed of Trust as against all or any portion of the Mortgaged Property and to have such property sold under the judgment or decree of a court of competent jurisdiction.

     5.7 Mortgagee May Purchase. It is expressly understood that the Mortgagee, or the Trustee, may be a purchaser of the Mortgaged Property, or of any part thereof, at any sale thereof, whether such sale be under the power of sale hereinabove vested in the Trustee or upon any other foreclosure of the lien and/or security interest hereof, or otherwise; and the Mortgagee or the Trustee so purchasing shall, upon any such purchase, acquire good title to the Mortgaged Property so purchased, free of the lien and/or security interest of this Deed of Trust and free of all rights of redemption in Mortgagor.

     5.8 Cumulative Rights. The rights of entry, sale, or suit, as hereinabove or hereinafter conferred, are cumulative of all other rights and remedies herein or by law or in equity provided, and shall not be deemed to deprive the Mortgagee or Trustee of any such other legal or equitable rights or remedies, by judicial proceedings or otherwise, appropriate to enforce the conditions, covenants and terms of this Deed of Trust and of any note or guaranty reflecting the Secured 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.

     5.9 No Appraisement. To the full extent Mortgagor may do so, Mortgagor agrees that Mortgagor will not at any time insist upon, plead, claim or take the benefit or advantage of any law now or hereafter in force providing for any appraisement, valuation, stay, extension or redemption, and Mortgagor, for Mortgagor and Mortgagor’s successors and assigns, and for any and all persons ever claiming any interest in the Mortgaged Property, to the extent permitted by law, hereby waives and releases all rights of redemption, valuation, appraisement, stay of execution, notice of intention to mature or declare due the whole of the Secured Indebtedness, notice of election to mature or declare due the whole of the Secured Indebtedness (excluding any notices which may be required prior to an Event of Default) and all rights to a marshaling of the assets of Mortgagor, including the Mortgaged Property, or to a sale in inverse order of alienation in the event of foreclosure of the liens and security interests hereby created. Mortgagor will not have or assert any right under any statute or rule of law pertaining to the marshaling of assets,

sale in inverse order of alienation, or other matters whatever to defeat, reduce or affect the right of the Mortgagee under the terms of this Deed of Trust to a sale of the Mortgaged Property for the collection of the Secured Indebtedness without any prior or different resort for collection, or the right of the Mortgagee under the terms of this Deed of Trust to the payment of such indebtedness out of the proceeds of sale of the Mortgaged Property in preference to every other claimant whatever. If any law referred to in this Section 5.9 and now in force, of which Mortgagor or Mortgagor’s successors and assigns and such other persons claiming any interest in the Mortgaged Property might take advantage despite this Section 5.9, shall hereafter be repealed or cease to be in force, such law shall not thereafter be deemed to preclude the application of this Section 5.9.

     5.10 Power of Attorney and Agent. Upon the occurrence or happening of an Event of Default, Mortgagor does hereby designate each of Trustee and Mortgagee as the agent and attorney in fact of Mortgagor to act in the name, place, and stead of Mortgagor in the exercise of each and every remedy set forth herein, including rights to liens on and security interests in the Mortgaged Property, and in conducting any and all operations and taking any and all action reasonably necessary to do so, recognizing such agency in favor of each of Trustee and Mortgagee to be coupled with the interests of Trustee and Mortgagee, respectively, under this Deed of Trust and, thus, irrevocable so long as this Deed of Trust is in force and effect.

     5.11 Events of Default. The term “Event of Default” as used herein shall mean the occurrence or happening, at any time and from time to time, of any one or more of the following:

	(a)		Mortgagor shall fail, refuse, or neglect to pay, in full, any installment or portion of the Secured Indebtedness as and when the same shall become due and payable, whether at the due date thereof stipulated herein or in the Note, upon acceleration or otherwise, provided that Mortagor has received all applicable notices of payment as provided in the Note;
	(b)		Mortgagor shall fail, refuse or neglect or cause the failure, refusal or neglect to comply with, perform and discharge fully and timely as and when required any of the material obligations of Mortgagor under this Deed of Trust or the Note, and Mortgagor fails to cure such non-compliance, non-performance or non-discharge within twenty (20) days of the receipt of written notice of same from Mortgageee;

	(e)		Any representation or warranty that relates to this Deed of Trust or the Note made by Mortgagor in the Purchase and Sale Agreement between Mortgagee and Mortgagor dated October 19, 2010, as thereafter amended (the “PSA”), is false or

Mortgagor further agrees to perform all such acts, and to execute all such further assignments, transfer and division orders, and other instruments as may be required or desired by Mortgagee or any other party to have such Hydrocarbon Proceeds so paid to Mortgagee.

Revenues

     Upon the occurrence of happening of an Event of Default, 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 the income, revenues, rents, issues, profits and proceeds arising from the Pipelines relating to the Mortgaged Property whether due, payable or accruing (collectively, the “Revenues”) under any and all present and future contracts or other agreements relating to the transmission of the Hydrocarbons or the ownership of all or any portion of the Mortgaged Property. Mortgagor hereby directs any payor to pay to Mortgagee such Revenues derived from such contracts and agreements, and to continue to make payments directly to Mortgagee until notified in writing by Mortgagee to discontinue the same; and the payor shall have no duty or obligation to inquire into the right of Mortgagee to receive the same, what application is made thereof, or as to any other matter; and the payment made to Mortgagee shall be binding and conclusive as between such payor and Mortgagor. Mortgagor agrees to perform all such acts, and to execute all such further assignments, transfers and other instruments as may be required or desired by the Mortgagee or any party in order to have said Revenues so paid to the Mortgagee.

General

     Upon the occurrence of happening of an Event of Default, the Mortgagee is fully authorized to (i) receive and receipt for said Revenues and Hydrocarbon Proceeds; (ii) to endorse and cash any and all checks and drafts payable to the order of Mortgagor or the Mortgagee for the account of Mortgagor received from or in connection with said Revenues and Hydrocarbon Proceeds and apply the proceeds thereof to the payment of the Secured Indebtedness, when received, regardless of the maturity of any of the Secured Indebtedness, or any installment thereof, and (iii) execute any instrument in the name of Mortgagor to facilitate any of the foregoing. Upon receipt of written instructions from Mortgagor, Mortgagee agrees to release to Mortgagor any Revenues and Hydrocarbon Proceeds belonging to third parties; provided that the Mortgagee shall not be liable for any delay, neglect, or failure to effect collection of any Revenues and Hydrocarbon Proceeds or to take any other action in connection therewith or hereunder; but shall have the right, at its election, in the name of Mortgagor or otherwise, to prosecute and defend any and all actions or legal proceedings deemed advisable by the Mortgagee in order to collect such funds and to protect the interests of the Mortgagee and/or Mortgagor, with all costs, expenses and attorney’s fees incurred in connection therewith being paid by Mortgagor. Unless Mortgagee has claimed or is claiming, for its benefit Revenues and Hydrocarbon Proceeds belonging to third parties and not attributable to the Mortgaged Property, Mortgagor hereby agrees to indemnify the Mortgagee against all claims, actions, liabilities, judgments, costs, charges and reasonable attorneys’ fees made against or incurred by it, based on the assertion that it received Revenues claimed by third persons either before or after the payment in full of the Secured Indebtedness, but in each case except for such claims, actions, liabilities, judgments, costs, charges and attorneys’ fees to the extent directly resulting from the gross negligence or willful misconduct of the Mortgagee. Mortgagee shall have the right to defend against any such claims, actions and judgments, employing its attorneys therefor, and if it is not furnished with reasonable indemnity, it shall have the right to compromise and adjust any such claims, actions and judgments. Mortgagor agrees to indemnify and pay to the Mortgagee any and all such claims, judgments, costs, charges and attorney’s fees as may be paid in any judgment, release or discharge thereof or as may be adjudged against the Mortgagee. Mortgagor hereby appoints Mortgagee as its attorney-in-fact to pursue any and all rights of Mortgagor to liens on and security interests in the Mortgaged Property. Mortgagor hereby further transfers and assigns to Mortgagee any and all such liens, security interests, financing statements or similar interests of Mortgagor attributable to its interest in the Mortgaged Property and Revenues and Hydrocarbon Proceeds arising under or created by any statutory provision, judicial decision or otherwise. The power of attorney granted to Mortgagee in this paragraph, being coupled with an interest, shall be irrevocable so long as the Secured Indebtedness or any part thereof remains unpaid. WITHOUT LIMITATION, THE FOREGOING INDEMNITIES SHALL APPLY TO EACH INDEMNIFIED PARTY WITH RESPECT TO MATTERS THAT IN WHOLE OR IN PART ARE CAUSED BY OR ARISE OUT OF THE NEGLIGENCE OF SUCH (AND/OR ANY OTHER) INDEMNIFIED PARTY OR ANY STRICT LIABILITY. SUCH INDEMNITIES SHALL NOT, HOWEVER, APPLY TO A PARTICULAR INDEMNIFIED PARTY TO THE EXTENT THAT THE SUBJECT OF THE INDEMNIFICATION IS CAUSED BY OR ARISES OUT OF THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF THAT INDEMNIFIED PARTY.

     6.2 Purchasers. Subject to the applicable terms of the Subject Contracts, should any purchaser taking the production from the Mortgaged Property fail to make prompt payment to Mortgagee in accordance with this Assignment, Mortgagee shall have the right at Mortgagor’s expense to negotiate directly with any other purchaser or, at that request of Mortgagee, the Mortgagor shall use reasonable commercial efforts to designate an alternative purchase and sale transaction in an effort, in either case, to cause such purchaser to pay any proceeds of production directly to Mortgagee or its designee.

     6.3 Collection 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 Secured Indebtedness or any part thereof to the contrary notwithstanding, Mortgagee may apply the same. Mortgagee agrees to give Mortgagor written notice simultaneously with its notice to the Purchaser that such payments are to be paid to Mortgagee in accordance with the terms of this Article VI.

     6.4 No Effect on Secure 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 Secured 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 Secured 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 Secured 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 securing the Secured Indebtedness or Mortgagor’s liability therefor. The rights under this Assignment are cumulative of all other rights, remedies, and powers 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 Secured Indebtedness.

     6.5 Trust. Should Mortgagor receive any of the proceeds of any sale of Hydrocarbons and Other Minerals produced, saved or 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.

     6.6 Full Payment. Upon payment in full of all Secured Indebtedness, the remainder of such proceeds held by Mortgagee, if any, shall be paid over to Mortgagor upon demand, and a release of the interest hereby assigned will be made by Mortgagee to Mortgagor at its request and its expense.

     6.7 No Liability. Except for Mortgagee’s gross negligence or willful misconduct, Mortgagee shall not be liable for any failure to collect, or for any failure to exercise diligence in collecting, any funds assigned hereunder, but only to the extent Mortgagee has successfully exercised its rights to collect such funds. Mortgagee shall be accountable only for funds actually received.

     6.8 Effective Date of the Assignment. Mortgagor hereby acknowledges that this Assignment under this Article VI, and the terms therein, shall only be effective upon the occurrence or happening of an Event of Default. Furthermore, Mortgagor agrees that Mortgagee is not required to assert any affirmative act, including the institution of any legal proceedings, to enforce this Assignment.

     6.9 Collection of Proceeds. Notwithstanding such assignments, if an Event of Default has not occurred then Mortgagee shall allow Mortgagor to collect proceeds of the production assigned herein until an Event of Default occurs.

ARTICLE VII

ADDITIONAL REMEDIES

     7.1 Expenses; Interest. If Mortgagor should fail to comply with any of the material covenants or material obligations of Mortgagor hereunder, which failure is not cured within twenty (20) days of receipt of written notice from Mortgagee, 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 reasonable expenses incurred or paid in so doing shall be payable by Mortgagor to Mortgagee, with interest at the rate agreed upon in the Note, from the date when same was so incurred or paid, and the amount thereof shall be payable as provided in the Note 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 presumptively 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 Section 7.1 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 Secured Indebtedness at once due and payable but shall be cumulative of such right and all other rights herein given.

     7.2 Possession. In case any one or more of the Events of Default shall happen, then in each and every such case the Trustee or Mortgagee or any part thereof, whether or not the Secured Indebtedness shall automatically become due and payable or shall have been declared due and payable, as applicable, 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 and/or Mortgagee 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 so derived, first, to the cost of maintenance and operation of such Mortgaged Property; second, to the payment of all Secured Indebtedness secured hereby, principal and interest, application to be made first to interest and then to principal; and the balance thereof, if any, shall be paid to Mortgagor. Upon such payment of all such costs and Secured Indebtedness, the Mortgaged Property shall be returned to Mortgagor in its then condition and such Trustee and/or Mortgagee 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, gross negligence or willful misconduct.

     7.3 Agent. In case any one or more of the Events of Default shall happen, Mortgagor does hereby designate Mortgagee as Mortgagor’s agent to exercise each and every remedy set forth herein and to conduct any and all operations and take any and all action reasonably necessary to do so.

     8.13 Termination. This Deed of Trust, including the grant of a lien hereunder and all of Mortgagee’s and Trustee’s rights, powers and remedies in connection therewith, will remain in full force and effect regardless of whether the liability of any other obligor may have ceased, or irrespective of the validity or enforceability of any other instrument executed in connection with the Secured Indebtedness, and notwithstanding the reorganization, incapacity or bankruptcy of any obligor, or the reorganization, or bankruptcy of Mortgagor, or any other event or proceeding affecting Mortgagor or any obligor, but shall terminate and be of no further force and effect (other than the indemnity obligations and other continuing obligations hereunder) upon the earlier of (A) the date Mortgagee has executed a written release or termination statement regarding this Deed of Trust or (B) the date when all Secured Indebtedness has been paid in full.

     8.14 No Waiver. The failure or delay of Mortgagee to file or give any notice as to this Deed of Trust, or to exercise any right, remedy or option to declare the maturity of the principal debt, or any other sums hereby secured, or the payment by Mortgagee of any taxes, liens, charges or assessments, shall not be taken or deemed a waiver of any rights to exercise such right or option or to declare any such maturity as to any past or subsequent violations of any of such covenants or stipulations, and shall not waive or prejudice any right or lien hereunder. Any election or failure by Mortgagee to exercise any rights, remedies or options hereunder shall not constitute a waiver or prejudice the exercise of other rights or remedies existing hereunder. All rights, powers, immunities, remedies and liens of Mortgagee existing and to exist hereunder or under any other instruments, and all other or additional security, and Mortgagee’s rights at law and in equity, shall be cumulative and not exclusive, each of the other; and Mortgagee shall, in addition to the remedies herein expressly provided, be entitled to such other remedies as may now or hereafter exist at law or in equity for securing and collecting the Secured Indebtedness, for enforcing the covenants herein, and for foreclosing the liens hereof. Resort by Mortgagee to any remedy provided for hereunder or at law or in equity shall not prevent concurrent or subsequent resort to the same or any other remedy or remedies.

     8.15 Waiver of Covenants by Mortgagee. Any and all covenants in this Deed of Trust may from time to time by instrument in writing signed by the Mortgagee be waived to such extent and in such manner as the Mortgagee may desire, but no such waiver shall ever affect or impair the Mortgagee’s rights and remedies or liens and security interests hereunder, except to the extent specifically stated in such written instrument.

     8.16 Conflict. In the event of a conflict between the terms and provisions of this Deed of Trust and those of the Note, the terms and provisions of the Note shall govern and control. As used in this Deed of Trust, the term “Mortgagee” shall also refer to any other holder of the Secured Indebtedness.
