In addition, the Company proposes to grant the underwriters (the “Underwriters”) named in Schedule I attached to this agreement (this “Agreement”) an option to purchase up to an additional 360,723 Common Units on the terms set forth herein (the “Additional Units”). The Firm Units and the Additional Units, if purchased, are hereinafter collectively called the “Units.” Citigroup Global Markets Inc. is acting as the representative of the several Underwriters and in such capacity is referred to in this Agreement as the “Representative.”

The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”), on behalf of the Trust, and the Company wish to confirm as follows their agreement with you and the other several Underwriters, on whose behalf you are acting, in connection with the purchase of the Units from the Company.

1. Registration Statement and Prospectus. The Trust has prepared and filed with the Securities and Exchange Commission (the “Commission”) in accordance with the provisions of the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Act”), a registration statement on Form S-1 (File No. 333-172797), including a prospectus subject to completion, relating to the Units. Such registration statement, as amended, including the financial statements, exhibits, annexes and schedules thereto, at the time when it becomes effective and as thereafter amended by any post-effective amendment, is

referred to in this Agreement as the “Registration Statement.” The prospectus in the form included in the Registration Statement or, if the prospectus included in the Registration Statement omits certain information in reliance upon Rule 430A under the Act and such information is thereafter included in a prospectus filed with the Commission pursuant to Rule 424(b) under the Act or as part of a post-effective amendment to the Registration Statement after the Registration Statement becomes effective, the prospectus as so filed, is referred to in this Agreement as the “Prospectus.” The prospectus subject to completion in the form included in the Registration Statement at the time of the initial filing of such Registration Statement with the Commission and each such prospectus as amended from time to time until the date of the Prospectus is referred to in this Agreement as a “Preliminary Prospectus.” For purposes of this Agreement, “free writing prospectus” has the meaning ascribed to it in Rule 405 under the Act, and “Issuer Free Writing Prospectus” shall mean each free writing prospectus prepared by or on behalf of the Trust or the Company or used or referred to by the Trust or the Company in connection with the offering of the Units. “Time of Sale Information” shall mean the most recent Preliminary Prospectus, together with each free writing prospectus, if any, identified in Schedule II hereto and the information set out in Schedule III hereto. “Effective Date” means each date and time as of which any part of the Registration Statement was or is declared effective by the Commission. “Time of Sale” means 9:02 a.m., New York time, on April 12, 2011.

2. Agreements to Sell and Purchase. The Company hereby agrees to sell the Firm Units to the Underwriters and, upon the basis of the representations, warranties and agreements of the Company and the Trust herein contained and subject to all the terms and conditions set forth herein, each Underwriter agrees, severally and not jointly, to purchase from the Company at a purchase price of $28.13 per Unit (the “purchase price per Unit”), the number of Firm Units set forth opposite the name of such Underwriter in Schedule I hereto.

The Company hereby also agrees to sell to the Underwriters, and, upon the basis of the representations, warranties and agreements of the Company and the Trust herein contained and subject to all the terms and conditions set forth herein, the Underwriters shall have the right for 30 days from the date of the Prospectus to purchase from the Company up to 360,723 Additional Units at the purchase price per Unit of the Firm Units, less an amount per Unit equal to any distributions declared by the Trust and payable on each Firm Unit but not on each Additional Unit. The Additional Units may be purchased solely for the purpose of covering over-allotments, if any, made in connection with the offering of the Firm Units. If any Additional Units are to be purchased, each Underwriter, severally and not jointly, agrees to purchase the number of Additional Units (subject to such adjustments as you may determine to avoid fractional units) that bears the same proportion to the total number of Additional Units to be purchased by the Underwriters as the number of Firm Units set forth opposite the name of such Underwriter in Schedule I hereto bears to the total number of Firm Units. The option to purchase Additional Units may be exercised in whole or in part at any time or from time to time within 30 days after the date of the Prospectus.

The place of closing for the Firm Units and the Closing Date may be varied by agreement among the Representative, the Trust and the Company. The Trust and the Company hereby acknowledge that circumstances under which the Representative may provide notice to postpone the Closing Date as originally scheduled include any determination by the Trust, the Company or the Representative to recirculate to the public copies of an amended or supplemented Prospectus or a delay as contemplated by the provisions of Section 11 hereof.

account of such Underwriter, but any such payment shall not relieve such Underwriter from any of its obligations under this Agreement.

5. Covenants and Agreements. Each of the Company and the Trustee, on behalf of the Trust, covenants and agrees with the several Underwriters as follows:

(a) The Trust will use its best efforts to cause the Registration Statement and any amendments thereto to become effective, if it has not already become effective, and will advise you promptly and, if requested by you, will confirm such advice in writing (i) when the Registration Statement has become effective and the time and date of any filing of any post-effective Registration Statement or any amendment or supplement to any Preliminary Prospectus or the Prospectus and the time and date that any post-effective amendment to the Registration Statement becomes effective, (ii) if Rule 430A under the Act is employed, when the Prospectus has been timely filed pursuant to Rule 424(b) under the Act, (iii) of the receipt of any comments of the Commission, or any request by the Commission for amendments or supplements to the Registration Statement, any Preliminary Prospectus or the Prospectus or for additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of the suspension of qualification of the Units for offering or sale in any jurisdiction or the initiation of any proceeding for such purposes and (v) within the period of time referred to in Section 5(h) below, of any change in the condition (financial or other), business, prospects, properties, net worth or results of operations of the Trust, or of any event that comes to the attention of the Trust that makes any statement made in the Registration Statement or the Prospectus (as then amended or supplemented) untrue in any material respect or that requires the making of any additions thereto or changes therein in order to make the statements therein (in the case of the Prospectus, in light of the circumstances under which they were made) not misleading in any material respect, or of the necessity to amend or supplement the Prospectus (as then amended or supplemented) to comply with the Act or any other applicable law. If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, the Trust will make every reasonable effort to obtain the withdrawal or lifting of such order at the earliest possible time. The Trust will provide the Underwriters with copies of the form of Prospectus, in such number as the Underwriters may reasonably request, and file with the Commission such Prospectus in accordance with Rule 424(b) of the Act before the close of business on the first business day immediately following the date hereof.

(b) The Trust will furnish to you, without charge, a photocopy of the signed original of the Registration Statement as originally filed with the Commission and of each amendment thereto, including financial statements and all exhibits thereto, and will also furnish to you, without charge, such number of conformed copies of the Registration Statement as originally filed and of each amendment thereto as you may reasonably request.

(c) The Trust will promptly file with the Commission any amendment or supplement to the Registration Statement or the Prospectus that may, in the judgment of the Company, the Trust or the Representative, be required by the Act or requested by the Commission.

(f) The Company and the Trust will retain in accordance with the Act all Issuer Free Writing Prospectuses not required to be filed pursuant to the Act; and if at any time after the date hereof any events shall have occurred as a result of which any Issuer Free Writing Prospectus, as then amended or supplemented, would conflict with the information in the Registration Statement, the Preliminary Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or, if for any other reason it shall be necessary to amend or supplement any Issuer Free Writing Prospectus, to notify you and, upon your request, to file such document (if required to be filed pursuant to the Act) and to prepare and furnish without charge to each Underwriter as many copies as they may from time to time reasonably request of an amended or supplemented Issuer Free Writing Prospectus that will correct such conflict, statement or omission or effect such compliance.

(g) Prior to the execution and delivery of this Agreement, the Trust has delivered or will deliver to you, without charge, in such quantities as you have requested or may hereafter reasonably request, copies of each form of the Preliminary Prospectus. Consistent with the provisions of Section 5(h) hereof, the Trust consents to the use, in accordance with the provisions of the Act and with the securities or Blue Sky laws of the jurisdictions in which the Units are offered by the several Underwriters and by dealers, prior to the date of the Prospectus, of each Preliminary Prospectus so furnished by the Trust.

(h) As soon after the execution and delivery of this Agreement as is practicable and thereafter from time to time for such period as in the reasonable opinion of counsel for the Underwriters a prospectus is required by the Act to be delivered in connection with sales by any Underwriter or a dealer, and for so long a period as you may request for the distribution of the Units, the Trust will deliver to each Underwriter and each dealer, without charge, as many copies of the Prospectus (and of any amendment or supplement thereto) as they may reasonably request. The Trust consents to the use of the Prospectus (and of any amendment or supplement thereto) in accordance with the provisions of the Act and with the securities or Blue Sky laws of the jurisdictions in which the Units are offered by the several Underwriters and by all dealers to whom Units may be sold, both in connection with the offering and sale of the Units and for such period of time thereafter as the Prospectus is required by the Act to be delivered in connection with sales by any Underwriter or dealer. If at any time prior to the later of (i) the completion of the distribution of the Units pursuant to the offering contemplated by the Registration Statement or (ii) the expiration of prospectus delivery requirements with respect to the Units under Section 4(3) of the Act and Rule 174 thereunder, any event shall occur that in the judgment of the Company, the Trust or in the opinion of counsel for the Underwriters is required

to be set forth in the Prospectus (as then amended or supplemented) or should be set forth therein in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary to supplement or amend the Prospectus to comply with the Act or any other law, the Trust will forthwith prepare and, subject to Section 5(a) hereof, file with the Commission and use its best efforts to cause to become effective as promptly as possible an appropriate supplement or amendment thereto, and will furnish to each Underwriter who has previously requested Prospectuses, without charge, a reasonable number of copies thereof.

waives such extension in writing. The foregoing restrictions shall not apply to Dispositions of up to 116,010 Common Units by the Company to its certain eligible employees as incentive compensation, as described in the Registration Statement, Time of Sale Information and Prospectus.

(m) The Trust will file promptly all material required to be filed by it with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act or the rules and regulations of the Commission thereunder, subsequent to the date of the Prospectus and for so long as the delivery of a prospectus (or, in lieu thereof, the notice referred to in Rule 173(a) under the Act) is required in connection with the offering of the Units.

(n) The Company and the Trust will comply with all agreements and satisfy all conditions on their part to be complied with or satisfied pursuant to this Agreement on or prior to the Closing Date or the Additional Closing Date, as the case may be, and the Company and the Trust will advise the Underwriters prior to the Closing Date or the Additional Closing Date, as the case may be, if any statements to be made on behalf of the Company or the Trust in the certificates contemplated by Section 9 hereof would be inaccurate if made as of the Closing Date or the Additional Closing Date, as the case may be.

(o) The Company and the Trust will cooperate with you and counsel for the Underwriters in connection with the registration or qualification of the Units for offering and sale by the several Underwriters and by dealers under the securities or Blue Sky laws of such jurisdictions as you may reasonably designate and will file such consents to service of process or other documents as may be reasonably necessary in order to effect and maintain such registration or qualification for so long as required to complete the distribution of the Units; provided that in no event shall either the Company or the Trust be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to general service of process in suits, other than those arising out of the offering or sale of the Units, as contemplated by this Agreement and the Prospectus, in any jurisdiction where it is not now so subject. In the event that the qualification of the Units in any jurisdiction is suspended, the Company or the Trust shall so advise you promptly in writing.

	A.		The Company has and will have good and defensible title to the Subject Interests (as defined in the Conveyances) free and clear of all liens, encumbrances and defects except for Permitted Encumbrances (as defined in the Conveyances); none of which in the aggregate materially affect the value of the Subject Interests and do not materially interfere with the PDP Royalty Interest or the PUD Royalty Interest or the use made and proposed to be made of such Underlying Properties by the Company;

	B.		to the knowledge of the Company, there are no Prior Reversionary Interests (as such are included in the definition of Permitted Encumbrances) in the Subject Interests;

	C.		all contracts, agreements or underlying leases, which comprise a portion of the Subject Interests and which individually or in the aggregate are material to the Subject Interests, are in full force and effect, the Company has paid all rents and other charges to the extent due and payable thereunder, is not in

default under any of such underlying contracts, agreements or leases, has received no notice of default from any other party thereto and knows of no material default by any other party thereto;

	D.		the working interests in oil, gas and mineral leases or mineral interests that constitute a portion of the Subject Interests held by the Company or any of its subsidiaries reflect in all material respects the right of the Company or such subsidiary, as applicable, to explore or receive production from such Subject Interests, and the care taken by the Company with respect to acquiring or otherwise procuring such leases or mineral interests was generally consistent with standard industry practices for acquiring or procuring leases and interests therein to explore such for hydrocarbons;

(xv) Sufficiency of Mortgages. The Company has validly granted to, and the Trust currently possesses a lien on: (i) the Company’s interest in the Marcellus Shale Formation in the AMI (except the Producing Xxxxx and any other xxxxx which are already producing and not subject to the Royalty Interests) pursuant to a Mortgage, Assignment of Leases, Security Agreement, Fixture Filing and Financing Statement (the “Drilling Support Mortgage”) in order to secure the estimated amount of the drilling costs for the Trust’s interests in the

PUD Xxxxx (the “Drilling Support Lien”); and (ii) the PDP Royalty Interest and the PUD Royalty Interest pursuant to a Mortgage, Assignment of Leases, Security Agreement, Fixture Filing and Financing Statement (the “Royalty Interest Mortgage”) to provide protection to the Trust, in the event of a bankruptcy of the Company, against the risk that the PDP Royalty Interest or PUD Royalty Interest is not considered a real property interest (the “Royalty Interest Lien”). Each of the Drilling Support Mortgage and the Royalty Interest Mortgage is effective to create, in favor of the Trust, a valid and enforceable security interest (if any, in the case of the Royalty Interest Mortgage) in all of the rights, interests and properties set forth in the Drilling Support Mortgage and the Royalty Interest Mortgage, respectively, and defined therein as the “Mortgaged Properties.” Each of the Drilling Support Mortgage and the Royalty Interest Mortgage have been executed, delivered and duly acknowledged, and are filed with the Recorder of Deeds in the Register and Recorder’s Office of Xxxxxx County, Pennsylvania; and the lien of the Trust in the Mortgaged Properties has been perfected and such lien constitutes notice (under the law of the Commonwealth of Pennsylvania) to all third parties of the interest of the Trust in the Mortgaged Properties.

(xix) No Labor Disputes. No labor dispute with the employees of any of the Company exists or, to the knowledge of the Company, is imminent, that would reasonably be expected to have a Material Adverse Effect.

(xx) Insurance. The Company maintains insurance covering its properties, operations, personnel and businesses, including the Underlying Properties against such losses and risks, in such amounts and from such insurers as is commercially reasonable, when considered in conjunction with the Company’s self insurance practices, for the conduct of its businesses and the value of its properties. The Company has not received notice from any insurer or agent of such insurer that substantial capital improvements or other expenditures will have to be made in order to continue such insurance. The Company is in compliance with the terms of such policies in all material respects, and all such insurance is duly in full force and effect on the date hereof and will be duly in full force and effect on the Closing Date and any Additional Closing Date.

8. Indemnification and Contribution. Subject to the limitations in this paragraph, the Trust and the Company agree to indemnify and hold harmless you and each other Underwriter, the directors, officers, employees and agents of each Underwriter, each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and any “affiliate” (within the meaning of Rule 405 under the Act) of such Underwriter from and against any and all losses, claims, damages, liabilities and expenses, including reasonable costs of investigation and attorneys’ fees and expenses (collectively, “Damages”) arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Time of Sale Information, any Issuer Free Writing Prospectus or the Prospectus or in any amendment or supplement thereto or (ii) (A) the omission or alleged omission to state in the Registration Statement or in any amendment or supplement thereto any material fact required to be stated therein or necessary to make the statements therein not misleading or (B) the omission or alleged omission to state in any Preliminary Prospectus, any Issuer Free Writing Prospectus or the Prospectus or in any amendment or supplement thereto, any material fact necessary in order to

make the statements therein, in light of the circumstances under which they were made, not misleading, except to the extent that any such Damages arise out of or are based upon an untrue statement or omission or alleged untrue statement or omission that has been made therein or omitted therefrom in reliance upon and in conformity with the information furnished in writing to the Company by or on behalf of any Underwriter through you, expressly for use in connection therewith. This indemnification shall be in addition to any liability that the Company may otherwise have.

If any action or claim shall be brought against any Underwriter or any person in respect of which indemnity may be sought against the Trust or the Company, such Underwriter or such director, officer, employee, agent, controlling person or such affiliate (an “indemnified party”) shall promptly notify in writing the party against whom indemnification is being sought (the “indemnifying party”), but failure to so notify the indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this Section 8, and such indemnifying party shall assume the defense thereof, including the employment of counsel reasonably acceptable to such indemnified party and the payment of all reasonable fees of and expenses incurred by such counsel. Such Underwriter or any such indemnified party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party, unless (i) the indemnifying party has agreed in writing to pay such fees and expenses, (ii) the indemnifying party has failed to assume the defense and employ counsel reasonably acceptable to the indemnified party or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified party and the indemnifying party, and such indemnified party shall have been advised by its counsel that one or more legal defenses may be available to the indemnified party that may not be available to the Trust or the Company, as the case may be, or that representation of such indemnified party and any indemnifying party by the same counsel would be inappropriate under applicable standards of professional conduct (whether or not such representation by the same counsel has been proposed) due to actual or potential differing interests between them (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party (but the Trust or the Company, as the case may be, shall not be liable for the fees and expenses of more than one counsel for the Underwriters and such indemnified parties)). The indemnifying party shall not be liable for any settlement of any such action effected without its (their several) written consent, but if settled with such written consent, or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any Underwriter and any such indemnified party from and against any loss, claim, damage, liability or expense by reason of such settlement or judgment, but in the case of a judgment only to the extent stated in the first paragraph of this Section 8.

Notwithstanding the foregoing, the Trust shall not be obligated to make any payments to an indemnified party under this Section 8 until the earlier to occur of the following: (a) with respect to a final, nonappealable judgment of a court of competent jurisdiction or a settlement agreement, the Company has not paid such indemnified party the amount owed within 30 days of the due date under such judgment or settlement, (ii) with respect to expenses, the Company has not paid such indemnified party the amount owed within 30 days of submission by the

indemnified party for reimbursement of such expenses or (iii) the Company shall become the subject of any bankruptcy or insolvency proceedings or publicly declares its inability to pay its debts as they become due.

Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless (i) the Trust and the Trustee of the Trust and (ii) the Company, its directors, its principal executive, financial and accounting officers and any person who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act and any “affiliates” (within the meaning of Rule 405 under the Act) of the Company, to the same extent as the foregoing joint and several indemnity from the Trust and the Company to each Underwriter, but only with respect to information furnished in writing by or on behalf of such Underwriter through you expressly for use in the Registration Statement, the Prospectus, the Time of Sale Information, any Issuer Free Writing Prospectus or any Preliminary Prospectus, or any amendment or supplement thereto. If any action or claim shall be brought or asserted against the Trust, the Trustee of the Trust, the Company, any of its directors, its principal executive, financial and accounting officers or any such controlling person or affiliate of the Company based on the Registration Statement, the Prospectus, the Time of Sale Information or any Preliminary Prospectus, or any amendment or supplement thereto, and in respect of which indemnity may be sought against any Underwriter pursuant to this paragraph, such Underwriter shall have the rights and duties given to the Trust or the Company by the immediately preceding paragraph (except that if the Trust or the Company, as the case may be, shall have assumed the defense thereof such Underwriter shall not be required to do so, but may employ separate counsel therein and participate in the defense thereof, but the fees and expenses of such counsel shall be at such Underwriter’s expense), and the Trust, the Trustee of the Trust, the Company, their respective directors, any such officers and any such controlling persons, shall have the rights and duties given to the Underwriters by the immediately preceding and following paragraph.

In any event, neither the Trust nor the Company, as the case may be, will, without the prior written consent of the Representative, settle or compromise or consent to the entry of any judgment in any proceeding or threatened claim, action, suit or proceeding in respect of which the indemnification may be sought hereunder (whether or not the Representative or any of its indemnified parties is a party to such claim, action, suit or proceeding) unless such settlement, compromise or consent includes an unconditional release of all Underwriters and their indemnified parties from all liability arising out of such claim, action, suit or proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Underwriter or their indemnified parties.

If the indemnification provided for in this Section 8 is unavailable or insufficient for any reason whatsoever to an indemnified party in respect of any Damages referred to herein, then an indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Damages (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Trust on the one hand, and the Underwriters on the other hand, from the offering and sale of the Units or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative and several fault of the Company and the Trust on the one hand, and

the Underwriters on the other hand, in connection with the statements or omissions that resulted in such Damages as well as any other relevant equitable considerations. The relative and several benefits received by the Company and the Trust on the one hand, and the Underwriters on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus; provided that, in the event that the Underwriters shall have purchased any Additional Units hereunder, any determination of the relative benefits received by the Company and the Trust or the Underwriters from the offering of the Units shall include the net proceeds (before deducting expenses) received by the Company and the underwriting discounts and commissions received by the Underwriters, from the sale of such Additional Units, in each case computed on the basis of the respective amounts set forth in the table or in the notes to the table on the cover page of the Prospectus. The relative fault of the Company and the Trust on the one hand, and the Underwriters on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Trust on the one hand, or by the Underwriters on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Trust, the Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 was determined by a pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the Damages referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount of the underwriting commissions received by such underwriter in connection with the Units underwritten by it and distributed to the public. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 8 are several in proportion to the respective numbers of Firm Units set forth opposite their names in Schedule I hereto (or such numbers of Firm Units increased as set forth in Section 11 hereof) and not joint.

Any Damages for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as Damages are incurred after receipt of reasonably itemized invoices therefor. The indemnity, contribution and reimbursement agreements contained in this Section 8 and the representations and warranties of the Trust and the Company set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter, its directors, officers, employees, agents and affiliates or any person controlling any Underwriter, the Trust, the Trustee of the Trust or the Company, its directors or

officers or any person controlling the Company, (ii) acceptance of any Units and payment therefor hereunder and (iii) any termination of this Agreement. A successor to any Underwriter, or to any of its directors, officers, employees or agents or to any person controlling any Underwriter or any affiliate of any Underwriter, the Trustee of the Trust, or to the Company, its directors, officers, any person controlling the Company or any affiliate of the Company, shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 8.

10. Use of Free Writing Prospectus. Each Underwriter severally covenants with the Trust that it has not made and will not make any offer relating to the Units that would constitute a “free writing prospectus,” as defined in Rule 405 under the Act, required to be filed with the Commission without the consent of the Trust, not to be unreasonably withheld, other than any such offer included in an Issuer Free Writing Prospectus. Each of the Trust and the Company covenants with the Underwriters that it has not made and will not make any offer relating to the Units that would constitute a “free writing prospectus,” as defined in Rule 405 under the Act, required to be filed with the Commission without the consent of the Representative, not to be unreasonably withheld, other than any such offer included in an Issuer Free Writing Prospectus included in the Time of Sale Information.

15. No Fiduciary Duty. Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by any of the Underwriters, each of the Company and the Trust acknowledges and agrees that (i) nothing herein shall create a fiduciary or agency relationship between the Company or the Trust, on the one hand, and the Underwriters, on the other hand; (ii) the Underwriters have been retained solely to act as underwriters and are not acting as advisors, expert or otherwise, to either the Company or the Trust in connection with the offering provided for herein, the sale of the Units or any other services the Underwriters may be deemed to be providing hereunder, including, without limitation, with respect to the public offering price of the Units; (iii) the relationship between the Company and the Trust, on the one hand, and the Underwriters, on the other hand, is entirely and solely commercial, and the price of the Units

Assuming no purchase by the Underwriters of the Additional Units and the due authorization, execution and delivery of this Agreement, at the Closing Date, after giving effect to the offer and sale of the Units as described in the Time of Sale Information and the Prospectus, the Company will own 476,733 Common Units, 4,401,250 Subordinated Units and the right to receive Incentive Distributions, free and clear of all Liens (i) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the Company as a debtor is on file in the office of the Secretary of State of the State of Delaware or (ii) otherwise known to such counsel, without independent investigation, other than those created by or arising under the Delaware Statutory Trust Act.

2. Neither the filing of the Registration Statement nor the offer or sale of the Units as contemplated by the Underwriting Agreement, gives rise to any rights for or relating to the registration of any Trust Units or other securities of the Trust, except as have been waived.

3. None of (i) the offer or sale of the Units as described in the Time of Sale Information and the Prospectus, (ii) the execution, delivery and performance of this Agreement by the Trust or the Company nor (iii) the consummation of the transactions contemplated by this Agreement, violates or will violate federal law; provided, however, that with respect to the foregoing, such counsel need express no opinion with respect to federal securities laws or other anti-fraud laws.

4. No permit, consent, approval, authorization, order, registration, filing or qualification (“consent”) of or with any court, governmental agency or body under federal law is required in connection with (i) the offer or sale of the Units as described in the Time of Sale Information and the Prospectus, (ii) the execution, delivery and performance of this Agreement by the Trust or the Company or (iii) the consummation of the transactions contemplated by this Agreement except (A) for registration of the Units under the Act and consents required under the Exchange Act, and applicable state securities or “Blue Sky” laws in connection with the purchase and distribution of the Units by the Underwriters or (B) for such consents that have been, or prior to the Closing Date will be, obtained or made.

5. The statements set forth in the Registration Statement, the Time of Sale Information and the Prospectus under the captions “The Trust,” “Target Distributions and Subordination and Incentive Thresholds,” “Description of the Trust Agreement,” “Description of the Trust Units,” and “ERISA considerations” and “The Royalties—Regulation,” insofar as they purport to constitute summaries of provisions of federal statutes, rules or regulations, of statutes, rules or regulations of the State of Delaware or of any specific agreement or instrument, constitute complete and accurate summaries thereof in all material respects; and the descriptions of the Trust Units contained in the Registration Statement, the Time of Sale Information and the Prospectus under the captions “Summary,” “The Trust,” “Target Distributions and Subordination and Incentive Thresholds,” “The Royalties,” “Description of the Trust Agreement,” and

A-1

6. The opinion letter of Xxxxxx & Xxxxxx L.L.P. that is filed as Exhibit 8.1 to the Registration Statement is confirmed, and the Underwriters may rely upon such opinion letter as if it were addressed to them.

7. To the knowledge of such counsel, there are no (i) legal or governmental proceedings pending or threatened to which the Company, any of its subsidiaries or the Trust is a party or to which any of their respective properties is subject that are required to be described in the Registration Statement, the Time of Sale Information or the Prospectus but are not so described as required by the Act or (ii) agreements, contracts, indentures, leases or other instruments that are required to be described in the Registration Statement, the Time of Sale Information and the Prospectus or to be filed as exhibits to the Registration Statement that are not described or filed as required by the Act.

8. The Registration Statement was declared effective under the Act as of the date and time specified in such opinion; to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission; and any required filing of the Prospectus pursuant to Rule 424(b) under the Act has been made in the manner and within the time period required by such Rule.

9. The Registration Statement, on the latest effective date and on the Closing Date and Additional Closing Date, and the Prospectus, when filed with the Commission pursuant to Rule 424(b) and on the Closing Date and the Additional Closing Date, appeared, on their face, appropriately responsive, in all material respects, to the requirements of the Act and the rules and regulations thereunder, except that in each case such counsel need express no opinion with respect to the financial statements and the notes and schedules thereto and the independent public accounting firm’s report thereon, the oil and gas reserve data, or other financial data, accounting data and statistical data derived from financial data contained in or omitted from the Registration Statement, the Time of Sale Information or the Prospectus.

10. Neither the Company, its subsidiaries nor the Trust is, or after giving effect to the offer and sale of the Units and the application of the net proceeds from such sale as described in the Registration Statement, the Time of Sale Information and the Prospectus under the caption “Use of Proceeds,” will be an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

In addition, such counsel shall state that they have reviewed the Registration Statement, the Time of Sale Information and the Prospectus and have participated in conferences with officers and other representatives of the Company, the independent registered public accounting firm of the Trust and representatives of the Underwriters, at which the contents of the Registration Statement, the Time of Sale Information and the Prospectus and related matters were discussed, and although such counsel has not independently verified, is not passing upon, and is not assuming any responsibility for the accuracy, completeness or fairness of the statements contained in, the Registration Statement, the Time of Sale Information and the

A-2

Prospectus (except to the extent specified in the foregoing opinions), based on the foregoing, no facts have come to such counsel’s attention that lead such counsel to believe that:

(A) the Registration Statement, at the time it was declared effective, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(B) the Time of Sale Information, as of the Time of Sale, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

(C) the Prospectus, as of its date and as of the Closing Date or the Additional Closing Date, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that such counsel expresses no statement or belief with respect to (a) the financial statements and related schedules, including the notes thereto and the independent public accounting firm’s report thereon, (b) the oil and gas reserve data, or (c) other financial data, accounting data and statistical data derived from financial data contained therein or omitted therefrom.

In rendering such opinion, such counsel may (i) rely in respect of matters of fact upon certificates of officers and other employees of the Company and of the Trustee and upon information obtained from public officials, (ii) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, (iii) state that their opinion is limited to federal laws, the Delaware General Corporation Law and the laws of the State of New York, (v) state that they express no opinion with respect to (A) any permits to own or operate any real or personal property or (B) state or local taxes or state or local tax statutes to which the Company or the Trust may be subject, and (vi) with respect to the existence of any Lien for which a financing statement under the Uniform Commercial Code of any state is on file, such counsel’s opinion is based solely upon such counsel’s review of a specific search of such state’s Secretary of State (each of which shall be as of a date not more than 10 days prior to the Closing Date or the Additional Closing Date and shall be provided to counsel to the Underwriters).

EXHIBIT D

FORM OF OPINION OF KEEVICAN XXXXX XXXXXXX & XXXXXX LLC

1. The Company is duly registered or qualified to do business and is in good standing as a foreign corporation in the Commonwealth of Pennsylvania. Neither the Trust nor the Trustee is required to qualify to transact business or appoint an agent for service of process in the Commonwealth of Pennsylvania as a result of the ownership, operation or activities of the Trust or the Trustee with respect to the Trust (as all such activities are described in the Registration Statement, Time of Sale Information and the Prospectus), and such activities of the Trustee pursuant to the Trust Agreement will not require the appointment of an ancillary trustee in the Commonwealth of Pennsylvania, to the extent the aforementioned involve acquiring real estate and mortgages and other liens thereon and personal property and security interests therein, and holding, leasing, conveying and transferring them, as fiduciary or other.

2. Each of the Conveyances, the Drilling Support Mortgage and the Royalty Interest Mortgage constitutes a valid and legally binding agreement of the parties thereto, enforceable against each of them in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

3. The Conveyances recorded were adequate and sufficient under the laws of the Commonwealth of Pennsylvania to transfer title to the Royalty Interests to the Trust and comply with the laws of the Commonwealth of Pennsylvania relating to recording, filing and registration laws and regulations; the recording of the Conveyances with the Recorder of Deeds in the Register and Recorder’s Office of Xxxxxx County, Pennsylvania is sufficient to provide the Trust the protections afforded under the recordation laws of the Commonwealth of Pennsylvania against purchasers or creditors of the Company subsequently acquiring interests in the Subject Interests, and such purchasers and creditors of the Company will be deemed to purchase with notice of, and subject to, such Royalty Interests; and the Company is not required to make any recordings or filings of the Conveyances under the laws of the Commonwealth of Pennsylvania other than those recordings or filings described in this paragraph.

4. Each of the Drilling Support Mortgage and the Royalty Interest Mortgage (together with all UCC-1 Financing Statements, deeds of trust and other documentation in connection with and necessary to perfect the Drilling Support Lien and the Royalty Interest Lien) were effective to create, in favor of the Trust, a valid and enforceable security interest in all of the rights, interests and properties set forth in the Drilling Support Mortgage and the Royalty Interest Mortgage, respectively and defined therein as the “Mortgaged Properties.” Each of the Drilling Support Mortgage and the Royalty Interest Mortgage have been executed, delivered, duly acknowledged and attested, and have been recorded with the Recorder of Deeds in the Register and Recorder’s Office of Xxxxxx County, Pennsylvania. All UCC-1 Financing Statements in connection with the Drilling Support Mortgage and the Royalty Interest Mortgage have been executed delivered, and filed with the Pennsylvania Department of State, and the lien of the Trust in the Mortgaged Properties has been perfected and such lien is notice (under the

D-1

law of the Commonwealth of Pennsylvania) to all third parties of the interest of the Trust in the Mortgaged Properties. With respect to the foregoing, such counsel need express no opinion in regard to the priority of liens as between the Drilling Support Mortgage and the Royalty Interest Mortgage.

5. None of (i) the offer or sale of the Units as described in the Time of Sale Information and the Prospectus, (ii) the execution, delivery and performance of this Agreement nor (iii) the consummation of the transactions contemplated by this Agreement violates or will violate any statute, law or regulation of any court or governmental agency or body of the Commonwealth of Pennsylvania.

6. No permit, consent, approval, authorization, order, registration, filing or qualification (“consent”) of or with any court, governmental agency or body of the Commonwealth of Pennsylvania, or under the laws of the Commonwealth of Pennsylvania is required in connection with (i) the offer or sale of the Units as described in the Time of Sale Information and the Prospectus, (ii) the execution, delivery and performance of this Agreement or (iii) the consummation of the transactions contemplated by this Agreement except (A) for consents required under applicable state securities or “Blue Sky” laws in connection with the purchase and distribution of the Units by the Underwriters or (B) for such consents that have been, or prior to the Closing Date will be, obtained or made.

7. A beneficial owner of a Trust Unit will not be subject to personal liability under state and local laws in the Commonwealth of Pennsylvania as a result of said ownership, including liability regulating the discharge of materials into the environment or otherwise relating to the protection of the environment.

In rendering such opinion, counsel may rely, to the extent they deem such reliance proper, as to matters of fact upon certificates of officers of the Company and of government officials, provided that counsel shall state their belief that they and you are justified in relying thereon. Copies of all such certificates shall be furnished to you and your counsel on the Closing Date and the Additional Closing Date, as the case may be. With respect to the opinion expressed as to the due qualification or registration as a foreign corporation of the Company, state that such opinion is based upon certificates of foreign qualification or registration provided by the Secretary of State of the Commonwealth of Pennsylvania (which shall be dated as of a date not more than 10 days prior to the Closing Date and the Additional Closing Date and shall be provided to counsel to the Underwriters) and express no conclusions beyond what are stated in such certificate.

FORM OF OPINION OF XXXXXXXX, XXXXXX & FINGER, P.A.

6. This Agreement has been duly authorized by the Trust.

7. None of (i) the offer or sale of the Units as described in the Time of Sale Information and the Prospectus, (ii) the execution, delivery and performance by the Trust of this Agreement nor (iii) the consummation by the Trust of the transactions contemplated hereby (A) requires the consent or approval of, the withholding of objection on the part of, the giving of notice to, the filing, registration or qualification with, or the taking of any other action in respect of, any governmental authority or agency of the State of Delaware under the Delaware Statutory Trust Act or (B) violates the Trust Agreement, the Certificate of Trust or any law, rule or regulation of the State of Delaware applicable to the Trust (assuming, in each case, compliance with all applicable state securities and Blue Sky laws, including the Blue Sky laws of the State of Delaware).

8. The Trust Unit Holders, as beneficial owners of the Trust, are entitled to the same limitation of personal liability extended to stockholders of private corporations for profit organized under the General Corporation Law of the State of Delaware. Such counsel notes that the Trust Unit Holders may be obligated to make payments as set forth in the Trust Agreement.

Re:		Restriction of Sales of ECA Marcellus Trust I Common Units

Dear Sirs:

This letter is delivered to you pursuant to the Underwriting Agreement (the “Underwriting Agreement”) to be entered into among ECA Marcellus Trust I, a statutory trust formed under the laws of the state of Delaware (the “Trust”), Energy Corporation of America, a West Virginia corporation (the “Company”), Citigroup Global Markets Inc., as the representative (the “Representative”) of the several underwriters (the “Underwriters”) listed on Schedule I thereto. Upon the terms and subject to the conditions of the Underwriting Agreement, (i) the Trust proposes to sell to the Underwriters units of beneficial interest (the “Units”) in the Trust, and (ii) the Underwriters intend to effect a public offering of the Units, as described in and contemplated by the registration statement of the Trust and the Company on Form S-1, File No. 333-172797 (the “Registration Statement”), as filed with the Securities and Exchange Commission on March 14, 2011 and as amended thereafter (the “Offering”).

The undersigned recognizes that it is in the best financial interests of the undersigned, as an officer or director of the Company, or an owner of Units or other securities of the Trust or other securities that are derived from the Subject Interests that are substantially similar to the Units (the “Trust Securities”), that the Company and Trust complete the proposed Offering.

The undersigned further recognizes that the Trust Securities held by the undersigned are, or may be, subject to certain restrictions on transferability, including those imposed by United States federal securities laws. Notwithstanding these restrictions, the undersigned has agreed to enter into this letter agreement to further assure the Underwriters that the Trust Securities of the

G-1

undersigned, now held or hereafter acquired, will not enter the public market at a time that might impair the underwriting effort.

Therefore, as an inducement to the Underwriters to execute the Underwriting Agreement, the undersigned hereby acknowledges and agrees that the undersigned will not (i) offer, sell, contract to sell, announce the intention to sell, pledge, grant or sell any option or contract to purchase or otherwise dispose of (collectively, a “Disposition”) any Trust Securities, or any securities convertible into or exercisable or exchangeable for, or any rights to purchase or otherwise acquire, any Trust Securities held by the undersigned or acquired by the undersigned after the date hereof, or that may be deemed to be beneficially owned by the undersigned (collectively, the “Lock-Up Units”), pursuant to the Rules and Regulations promulgated under the Securities Act of 1933, as amended (the “Act”), and the Securities Exchange Act of 1934, as amended, for a period commencing on the date hereof and ending 60 days after the date of the Prospectus first filed pursuant to Rule 424(b) under the Act, inclusive (the “Lock-Up Period”), without the prior written consent of the Representative or (ii) exercise or seek to exercise or effectuate in any manner any rights of any nature that the undersigned has or may have hereafter to require the Company or the Trust to register under the Act the undersigned’s sale, transfer or other disposition of any of the Lock-Up Units or other securities of the Trust held by the undersigned, or to otherwise participate as a selling securityholder in any manner in any registration effected by the Company or the Trust under the Act, including under the Registration Statement, during the Lock-Up Period. The foregoing restrictions are expressly agreed to preclude the undersigned from (x) entering into any swap or other agreement that transfers any of the economic consequences of ownership of or otherwise transfer or dispose of, directly or indirectly, any of the Lock-Up Units or (y) entering into any hedging, collar (whether or not for any consideration) or other transaction or arrangement that is designed to or reasonably expected to lead or result in a transfer, in whole or part, of any of the economic consequences of ownership of the Lock-Up Units. Such prohibited hedging or other transactions would include any short sale or any purchase, sale or grant of any right (including any put or call option or reversal or cancellation thereof) with respect to any Lock-Up Units or with respect to any security (other than a broad-based market basket or index) that includes, relates to or derives any significant part of its value from Lock-Up Units.

Notwithstanding the foregoing if (i) during the last 17 days of the Lock-Up Period, the Trust issues an earnings release or announces material news or a material event relating to the Trust occurs or (ii) prior to the expiration of the Lock-Up Period, the Trust announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then the Lock-Up Period shall continue until the expiration of the 18-day period beginning on the date of issuance of the earnings release or the announcement of the material news or the occurrence of the material event, unless the Representative, on behalf of the Underwriters, waives such extension in writing.

It is understood that, if the Underwriting Agreement (other than the provisions thereof that survive termination) shall terminate or be terminated prior to payment for and delivery of the Units, you will release the undersigned from the obligations under this letter agreement.

G-2

In furtherance of the foregoing, the Trust and its transfer agent and registrar are hereby authorized to decline to make any transfer of Lock-Up Units if such transfer would constitute a violation or breach of this letter. This letter shall be binding on the undersigned and the respective successors, heirs, personal representatives and assigns of the undersigned. Capitalized terms used but not defined herein have the respective meanings assigned to such terms in the Underwriting Agreement.


		Very truly yours,
