5.7. Restrictions on Liens.

5.9. Additional Improvements for the Property.

The Primary Financing Parties understand that the Lessee is contemplating the construction at some later time of another building on the Land which is subject to the Ground Lease and constitutes a portion of the Property. If and when the Lessee has a more definitive plan in place with regard to the construction of such additional building, the Primary Financing Parties (a) would welcome the opportunity to review and discuss such plans with the Lessee and

(b) would consider financing the construction of such additional building. For the avoidance of doubt and notwithstanding any provision of this Section 5.9 or any other provision of any Operative Agreement, however, no Primary Financing Party has made any commitment of any kind to provide financing for the construction of such additional building, and the determination to make any such commitment would be left to the sole discretion of each Primary Financing Party.

(ii) Without limiting Section 5.11(c)(i) above the Lessee shall transfer such Additional Liquid Collateral to the Liquid Collateral Account by the

Additional Collateral Delivery Date to ensure that the Adjusted Market Value, in the case of Properly Margined Liquid Collateral (in which the Agent, for the benefit of the Secured Parties, has a first priority perfected security interest) shall be greater than or equal to the applicable Required Liquid Collateral Amount.

(d) Pursuant to, and subject to the requirements of, the Liquid Collateral Agreements, the Agent shall have the right to direct the reinvestment of any Pledged Securities credited to the Liquid Collateral Account upon the maturity of such Pledged Securities or prior thereto into one or more Permitted Investments constituting Liquid Collateral.

(e) The parties hereto acknowledge and agree that (i) any Permitted Investments transferred to the Liquid Collateral Account pursuant to Sections 5.11(a), 5.11(c) or 5.11(d) or otherwise shall be deemed Pledged Securities for the purposes of this Agreement, (ii) on any transfer date, the Agent shall instruct the Lessee and the Intermediary to take or cause to be taken, and the Lessee and the Intermediary shall take or cause to be taken such action as is necessary to create in the Lessor a valid perfected first priority security interest on such date in such Pledged Securities, and (iii) on any transfer date, the Agent shall instruct the Lessee, the Lessor and the Intermediary to take or cause to be taken, and the Lessee, the Lessor and the Intermediary shall take or cause to be taken such action as is necessary to create in the Agent a valid perfected first priority security interest on such date in the Lessor’s right, title and interest in, to and under such Pledged Securities. Without limiting the foregoing, the Agent is hereby authorized to complete Exhibit K hereto upon acquisition of such Pledged Securities and deposit of same into the Liquid Collateral Account. The costs and expenses incurred by the parties to this Agreement pursuant to this Section 5.11(e) shall constitute Transaction Expenses payable by the Lessor pursuant to Section 7.1 (subject to Section 5.17) prior to the Commencement Date and payable by the Lessee pursuant to Section 7.3 from and after the Commencement Date.

(f) To the extent no Lease Default, Lease Event of Default, Agency Agreement Default or Agency Agreement Event of Default shall have occurred and be continuing and to the extent the Liquid Collateral in the Liquid Collateral Account has an Adjusted Market Value of Properly Margined Liquid Collateral in excess of the Required Liquid Collateral Amount, the Lessee may request the Agent to cause some or all of such excess Liquid Collateral to be released from the Liquid Collateral Account and the lien of the Security Documents. In such case, the Agent shall instruct the Intermediary to release such specified excess Liquid Collateral to the Lessee or pursuant to the instruction of the Lessee.

(g) To the extent no Lease Default, Lease Event of Default or Agency Agreement Event of Default shall have occurred and be continuing, the Agent shall not deliver a Notice of Exclusive Control to the Intermediary.

5.16. Overdue Amounts.

Unless otherwise expressly stated pursuant to any Operative Agreement, all amounts not paid when due and owing pursuant to any Operative Agreement shall bear Interest at the Overdue Rate from and including the due date for such amount to but excluding the date such amount is actually paid.

5.17. Cap on Construction Advance for Construction Agent Reimbursement.

Notwithstanding the fact that not all conditions precedent under Section 5.4 are satisfied at a given time when a Construction Advance is being sought by the Construction Agent for amounts previously paid by the Construction Agent, so long as no Full Recourse Event of Default is continuing and provided the conditions precedent set forth in Sections 5.4(c), 5.4(f), 5.4(g), 5.4(h)(ii) and 5.4(m) are satisfied at such time, the Lessor and the Lenders shall make their respective Advances prior to the Commencement Date (subject to the Advance Cap) for each Construction Advance in accordance with the applicable Requisition (in order to reimburse the Construction Agent for amounts previously paid by the Construction Agent which are eligible for reimbursement by Advances but have not been so reimbursed) up to an aggregate amount for all such Construction Advances not to exceed $2,000,000 (the “Advance Cap”); provided, the initial Advance and any Advance when all conditions precedent under Section 5.4 are satisfied shall not be so limited; provided, further, if one or more Construction Advances are made which are subject to and limited by the Advance Cap and thereafter the Construction Agent has corrected the situation which was preventing satisfaction of all conditions precedent under Section 5.4 in connection with the Construction Advances, then (after such correction of the

situation) no such prior Construction Advance shall continue to count against the Advance Cap and the balance of the Advance Cap shall be reduced to zero.

5.18. Release of Liens Concerning Non-Integral Equipment.

The Agent is hereby authorized and directed by all the Secured Parties to grant releases requested from time to time by the Lessee from the Liens of the Security Documents with respect to Non-Integral Equipment which has not been financed with any Advance or with any Casualty proceeds, Condemnation proceeds or insurance proceeds from insurance policies required to be maintained pursuant to the Operative Agreements. Prior to the Agent’s execution and delivery of any such release, the Lessee must certify in writing to the Financing Parties that the subject property is in fact Non-Integral Equipment which has not been financed with any Advance or with any Casualty proceeds, Condemnation proceeds or insurance proceeds from insurance policies required to be maintained pursuant to the Operative Agreements. Unless the Majority Secured Parties object to the characterization of any item as Non-Integral Equipment which has not been financed with any Advance or with any Casualty proceeds, Condemnation proceeds or insurance proceeds from insurance policies required to be maintained pursuant to the Operative Agreements within ten (10) Business Days of their receipt of such Lessee certification, then the Agent is hereby directed by the Majority Secured Parties to execute and deliver such release to the Lessee.

5.19. Replacement of Intermediary.

Upon the Commencement Date, Wachovia Bank, National Association shall replace Xxxxx Xxxxxx, a division of Citigroup Global Markets Inc., as the Intermediary, and the Cash Collateral Control Agreement shall be amended, modified, supplemented, restated and/or replaced as Wachovia Bank, National Association and the Agent determine to be necessary.

SECTION 5A. LESSOR ADVANCE.

5A.1. Procedure for Lessor Advance.

(a) Upon receipt from the Construction Agent by the Agent of a Requisition pursuant to Section 4.2, and subject to the terms and conditions of this Agreement, the Lessor shall make an Advance under the Lessor Commitment equal to the amount of the Lessor Commitment on the Closing Date. The Lessor Advance shall be based on the Eurodollar Rate or the ABR, as designated by the Construction Agent in the Requisition.

(b) The Lessor Commitment shall be funded in full on the Closing Date in accordance with Section 5.2(c). Upon the occurrence of any Full Recourse Event of Default, the Lessee shall prepay the Lessor Advances in full, together with accrued but unpaid Lessor Yield thereon and all other amounts owing to the Lessor under the Operative Agreements.

5A.2. Lessor Yield.

(a) The Lessor Advance shall bear yield calculated at the rate of Lessor Yield applicable from time to time. The Lessee shall pay as Basic Rent to the Agent for distribution to the Lessor the Lessor Yield in arrears on each Payment Date or as otherwise provided herein or in Section 8.7 of this Agreement. During the Construction Period, Lessor Yield shall be paid to the Lessor out of Advances made pursuant to Section 5 and the other provisions of the Operative Agreements.

(b) If all or a portion of Lessor Yield shall not be received by the Lessor (or the Agent on behalf of the Lessor) when due (whether at the stated maturity, by acceleration or otherwise) for any reason other than the failure of the Lessor to fund a Lessor Advance in regard to the payment of such Lessor Yield at a time when the conditions precedent under the Operative Agreements have been satisfied in connection with such funding, such overdue amount shall, without limiting the rights of the Lessor hereunder or under any other Operative Agreement, bear interest at the Lessor Overdue Rate, in each case from the date of nonpayment until paid (whether after or before judgment) and shall be paid upon demand. Upon the occurrence and during the continuation of any Event of Default, Lessor Yield shall be calculated at the Lessor Overdue Rate.

5A.3. Scheduled Return of Lessor Advance.

The outstanding amount of the Lessor Advance shall be due in full on the Expiration Date. On the Expiration Date, subject to the terms of this Agreement and subject to the rights of the Lessee in connection with its election of the Sale Option in accordance with the Operative Agreements (including without limitation relating to the Maximum Residual Guarantee Amount), the Lessor (or the Agent on behalf of the Lessor) shall receive from the Lessee as Basic Rent under the Lease the outstanding amount of the Lessor Advance then due, together with all accrued but unpaid Lessor Yield and all other amounts due to Lessor under the Operative Agreements.

5A.4. Early Return of Lessor Advance.

(a) Subject to Sections 11.2(e), 11.3 and 11.4 of this Agreement, the Lessor Advance may at any time and from time to time be prepaid by the Lessee as a payment of Supplemental Rent, in whole or in part, without premium or penalty, upon at least three (3) Business Days’ irrevocable notice to the Agent, on behalf of the Lessor, specifying the date and amount of prepayment of the Lessor Advance. Upon receipt of

such notice, the Agent shall promptly notify the Lessor thereof. If such notice is given, the amount specified in such notice shall be due and payable on the date specified therein. Amounts prepaid shall not be re-advanced.

(b) If on any date the Agent or the Lessor shall receive any payment in respect of (i) any Casualty, Condemnation or Environmental Violation pursuant to Sections 15.1(a), 15.1(g) or 15.2 or Article XVI of the Lease (excluding any payments in respect thereof which are payable to Lessee in accordance with the Lease), or (ii) the Termination Value of the Property in connection with the delivery of a Termination Notice pursuant to Article XVI of the Lease, or (iii) the Termination Value of the Property or such other applicable amount in connection with the exercise of a Purchase Option under Article XX of the Lease or the exercise of the option of the Lessor to transfer the Property to the Lessee pursuant to Section 20.3 of the Lease, then in each case, the Agent or the Lessor shall receive such payment to be distributed in accordance with Section 8.7(b) of this Agreement.

(c) Each prepayment of the Lessor Advances pursuant to Section 5A.4 shall be allocated to reduce the Property Cost based on the then current Property Cost immediately before giving effect to such prepayment.

(d) Each prepayment of the Lessor Advances (including without limitation pursuant to Sections 5A.4(a) or 5A.4(b)) shall be made on a Scheduled Interest Payment Date.

5A.5. Conversion and Continuation Options.

(a) Subject to Section 5A.5(c), the Lessee may elect from time to time to convert Eurodollar Lessor Advances to ABR Lessor Advances by giving the Lessor at least three (3) Business Days’ prior irrevocable notice of such election, provided, that any such conversion may only be made on the last day of an Interest Period with respect thereto, and provided, further, to the extent an Event of Default has occurred and is continuing on the last day of any such Interest Period, the applicable Eurodollar Lessor Advances shall automatically be converted to ABR Lessor Advances. Subject to Section 5A.5(c), the Lessee may elect from time to time to convert ABR Lessor Advances to Eurodollar Lessor Advances by giving the Lessor at least three (3) Business Days’ prior irrevocable notice of such election. All or any part of outstanding Lessor Advance may be converted as provided herein, provided, that (i) no ABR Lessor Advance may be converted into a Eurodollar Lessor Advance after the date that is one (1) month prior to the Expiration Date and (ii) such notice of conversion regarding any Eurodollar Lessor Advance shall contain an acknowledgment of the Lessee (subject to Section 5A.5(c)) of the requirements set forth in the definition of the term “Interest Period” including without limitation subparagraphs (A) through (C) thereof.

(b) Subject to the restrictions of Section 5A.1 of this Agreement, any Eurodollar Lessor Advance may be continued as such upon the expiration of the then current Interest Period with respect thereto by the Lessee (subject to Section 5A.5(c))

giving irrevocable notice to the Lessor, in accordance with the applicable notice provision for the conversion of ABR Lessor Advances to Eurodollar Lessor Advances set forth herein, provided, that no Eurodollar Lessor Advance may be continued as such after the date that is one (1) month prior to the Expiration Date, provided, further, no Eurodollar Lessor Advance may be continued as such if an Event of Default has occurred and is continuing as of the last day of the Interest Period for such Eurodollar Lessor Advance, provided, further, unless a Eurodollar Lessor Advance is not then permitted subject to the terms of this Agreement or the other Operative Agreements, if the Lessee (subject to Section 5.5(a)(c)) shall fail to give any required notice as described above or otherwise herein, such Lessor Advance (on the last day of such then expiring Interest Period) shall automatically be continued as a Eurodollar Lessor Advance with an Interest Period of one (1) month, consistent with the requirements set forth in the definition of the term “Interest Period”, and provided, further, if such continuation of a Eurodollar Lessor Advance is not permitted, such Lessor Advance shall automatically be converted to an ABR Lessor Advance on the last day of such then expiring Interest Period.

(c) The rights of the Lessee in this Section 5A.5 are subject to there being no Lease Default, Lease Event of Default, Agency Agreement Default or Agency Agreement Event of Default that has occurred and is continuing at the time any such right is to be exercised. To the extent any Lease Default, Lease Event of Default, Agency Agreement Default or Agency Agreement Event of Default has occurred and is continuing (and unless Lessor otherwise agrees in writing), any outstanding Eurodollar Lessor Advance will be converted into an ABR Lessor Advance at the end of the applicable Interest Period, and any ABR Lessor Advance will be continued as such. The rights of the Lessee shall be restored upon the cure or waiver of any such Lease Default, Lease Event of Default, Agency Agreement Default or Agency Agreement Event of Default in accordance with the Operative Agreements.

5A.6. Computation of Lessor Yield.

(a) Lessor Yield shall be calculated on the basis of a year of three hundred sixty (360) days for the actual days elapsed. Any change in the Lessor Yield resulting from a change in the Eurodollar Reserve Requirement shall become effective as of the opening of business on the day on which such change becomes effective.

(b) Pursuant to Section 12.12 of this Agreement, the calculation of Lessor Yield under this Section 5A.6 shall be made by the Agent. Each determination of Lessor Yield by the Agent shall be conclusive and binding absent demonstrable error.

(c) If the Eurodollar Rate cannot be determined by the Agent in the manner specified in the definition of the term “Eurodollar Rate”, then commencing on the Payment Date next occurring and continuing until such time as the Eurodollar Rate can be determined by the Agent in the manner specified in the definition of such term, the outstanding Lessor Advance shall bear a yield at the ABR.

Except for notices, reports and other documents expressly required to be furnished to the Primary Financing Parties by the Agent hereunder, the Agent shall not have any duty or responsibility to provide any Primary Financing Party with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of the Borrower or the Lessee which may come into the possession of the Agent or any of its officers, directors, employees, agents, attorneys-in-fact or Affiliates.

(h) Each of the Lessor and the Lenders (based on each such party’s pro rata share of the aggregate Commitments) agree to indemnify the Agent, in its capacity as such (to the extent not reimbursed by the Lessee and without limiting any obligation of the Lessee under and in accordance with the terms of the Operative Agreements to do so), ratably according to their respective Commitment Percentages in effect on the date on which indemnification is sought under this Section (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Notes and Lessor Advances shall have been paid in full, ratably in accordance with their Commitment Percentages immediately prior to such date), from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever which may at any time (including without limitation at any time following the payment of the Notes and the Lessor Advances) be imposed on, incurred by or asserted against any of them in any way relating to or arising out of, the Commitments, this Agreement, any of the other Operative Agreements or any documents contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by any of them under or in connection with any of the foregoing; provided, that no Primary Financing Party shall be liable for the payment of any portion of such liabilities, obligations, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting solely from the gross negligence or willful misconduct of the Agent, or its failure to use ordinary care in the handling of funds. The agreements in this Section shall survive the payment of the Notes and the Lessor Advances and all other amounts payable hereunder.

(i) The Agent and its Affiliates may make loans to, accept deposits from and generally engage in any kind of business with the Borrower or the Lessee as though the Agent were not the Agent hereunder and under the other Operative Agreements.

(j) (i) The Agent may resign at any time as the Agent upon sixty (60) days’ notice to the Primary Financing Parties, the Borrower and the Lessee. If the

Agent shall resign as the Agent under this Agreement, a successor Agent shall be appointed by the Majority Secured Parties which successor Agent shall be subject to the approval of, so long as no Lease Event of Default or Agency Agreement Event of Default shall have occurred and be continuing, the Lessee, such approval not to be unreasonably withheld or delayed. If no successor Agent is appointed prior to the effective date of the resignation of the resigning Agent, the Agent may appoint, after consulting with the Primary Financing Parties and subject to the approval of, so long as no Lease Event of Default or Agency Agreement Event of Default shall have occurred and be continuing, the Lessee, such approval not to be unreasonably withheld or delayed, a successor Agent. Any successor Agent, however appointed, shall be a bank or trust company incorporated and doing business within the United States of America and having a combined capital and surplus of at least $200,000,000, if there be such an institution willing, able and legally qualified to perform the duties of the Agent hereunder upon reasonable or customary terms. If no successor Agent has accepted appointment as the Agent by the date which is sixty (60) days following a retiring Agent’s notice of resignation, the retiring Agent’s notice of resignation shall nevertheless thereupon become effective and the Primary Financing Parties shall perform all of the duties of the Agent until such time, if any, as the Majority Secured Parties appoint a successor Agent, as provided for above. If no successor Agent shall have been appointed in accordance with the provisions of this Section 8.6(j)(i) on or before the effective date of such resignation, the Lessee shall pay Rent to such Person or Persons and at such location as the parties hereto shall agree at such time. Upon the effective date of such resignation, only such successor Agent shall succeed to all the rights, powers and duties of the retiring Agent and the term “Agent” shall mean such successor agent and the retiring Agent’s rights, powers and duties in such capacity shall be terminated. After any retiring Agent resigns hereunder as the Agent, the provisions of this Section 8.6 shall inure to such retiring Agent’s benefit as to any actions taken or omitted to be taken by it while it was the Agent under this Agreement.

(ii) The Agent may be removed (x) by the Majority Secured Parties in the case of fraud, misappropriation of funds or the commission of illegal acts by the Agent or where the Agent has failed to perform its obligations hereunder or under any other Operative Agreement in any material respect, or (y) any time at the request of any Primary Financing Party, but only with the consent of the Majority Secured Parties and so long as no Lease Event of Default or Agency Agreement Event of Default shall have occurred and be continuing, the Lessee. Any such removal shall be effective upon the acceptance of appointment of a successor Agent in accordance with the provisions of paragraph (i) of this Section 8.6(j); provided,however, to the extent the Agent being replaced pursuant to clause (x) of this Section 8.6(j)(ii) is also a Lender, such Person shall not be permitted to vote in connection with the appointment or approval of a successor Agent pursuant to paragraph (i) of this Section 8.6(j).

(k) Other than the exercise of reasonable care to assure the safe custody of the Collateral while being held by the Agent hereunder or under any other Operative Agreement, the Agent shall have no duty or liability to preserve rights pertaining thereto, it being understood and agreed that the Lessee shall be responsible for preservation of all rights in the Collateral, and the Agent shall be relieved of all responsibility for the Collateral upon surrendering it or tendering the surrender of it to the Lessee. The Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which the Agent accords its own property, which shall be no less than the treatment employed by a reasonable and prudent agent in the industry, it being understood that the Agent shall not have responsibility for taking any necessary steps to preserve rights against any parties with respect to any of the Collateral.

8.6A. Appointment of the Lessor by the Secured Parties.

(b) Notwithstanding anything to the contrary in Section 10.1(a), no consent shall be required from the Agent, the Lessee or any Primary Financing Party (but Lessor shall provide one hundred eighty (180) days (or such shorter period as required by the Legal Requirement giving rise to the assignment, conveyance, appointment or transfer contemplated by this Section 10.1(b)) written notice to the Agent and the Lessee) in connection with any assignment, conveyance, appointment or transfer by the Lessor required by any Legal Requirement of all or any of its right, title or interest in or to the Property, the Lease and the other Operative Agreements (including without limitation any right to indemnification thereunder), or any other document relating to the Property or any interest in the Property as provided in the Lease to an Eligible Lessor; provided, in such case, so long as no Lease Default, Lease Event of Default, Agency Agreement Default or Agency Agreement Event of Default shall have occurred and be continuing, the Lessee shall have the right to require the Lessor (unless such transfer or conveyance has already occurred, in which case the Lessee shall have the right to require such transferee) to transfer its interest to an Eligible Lessor selected by the Lessee, in its sole discretion; provided, further, the Lessee shall be responsible for any cost or expense incurred by the Lessor in connection with any assignment, conveyance, appointment or transfer by the Lessor pursuant to this Section 10.1(b).

From and after any transfer effected in accordance with this Section 10, the transferor shall be released, to the extent of such transfer, from its liability hereunder and under the other documents to which it is a party in respect of obligations to be performed on or after the date of such transfer; provided, however, that any transferor shall remain liable hereunder and under such other documents to the extent that the transferee shall not have assumed the obligations of the transferor thereunder. Upon any transfer by the Lessor or any other Primary Financing Party as above provided, any such transferee shall assume the obligations of the Lessor or such Primary Financing Party, as the case may be, and shall be deemed the “Lessor” and/or a “Primary Financing Party”, as the case may be, for all purposes of such documents and each reference herein to the transferor shall thereafter be deemed a reference to such transferee for all purposes, except as provided in the preceding sentence. Notwithstanding any transfer of all or a portion of the transferor’s interest as provided in this Section 10, the transferor shall be entitled to all benefits accrued and all rights vested prior to such transfer including without limitation rights to indemnification under any such document.

SECTION 11. INDEMNIFICATION.

11.1. General Indemnity.

Subject to the limitations set forth in Section 11.7 hereof, whether or not any of the transactions contemplated hereby shall be consummated, the Indemnity Provider hereby assumes liability for and agrees to defend, indemnify and hold harmless each Indemnified Person on an After Tax Basis from and against any Claims which may be imposed on, incurred by or asserted against an Indemnified Person by any third party, including without limitation Claims arising from the negligence of an Indemnified Person from and after the Commencement Date (but not to the extent such Claims arise from (x) the gross negligence or willful misconduct of such Indemnified Person, as determined by a court of competent jurisdiction or (y) a diminution in the Fair Market Sales Value of the Property unless such diminution is caused by or related to (i) any act or omission of the Indemnity Provider, any Person engaged by the Indemnity Provider, any Construction Agency Person or any Affiliate of any of the foregoing or (ii) any Default or Event of Default of the Lessee and/or the Construction Agent) and Claims for loss or damage, arising out of or as a result of the grant or denial of equitable relief in any way relating to or arising or alleged to arise out of the negotiation, execution, delivery, performance or enforcement of or compliance with this Agreement, the Lease or any other Operative Agreement or on or with respect to the Property or any component thereof, the Collateral or any component thereof, or the ownership of any Loan or Note or the making of any Lessor Advance, including without limitation Claims in any way relating to or arising or alleged to arise out of (a) the financing, refinancing, purchase, acceptance, rejection, ownership, transfer of ownership, design, construction, refurbishment, development, delivery, non-delivery, redelivery, leasing, subleasing, possession, use, occupancy, operation, maintenance, repair, modification, transportation, condition, sale, return, manufacture, ordering, transfer, titling or re-titling, registration or re-registration, storage, removal, mortgaging, granting any interest in, acquisition, repossession (whether by summary proceedings or otherwise), transfer of title to or other application or disposition of the Property or any part thereof or in the Collateral or any portion thereof,

Collateral or services that are the subject of any Collateral; (t) the use of the proceeds of any Loan or Lessor Advance in a manner other than as provided in the Operative Agreements; or (u) the failure of the Indemnity Provider or any of its respective agents or representatives to remit to the Lenders, the Lessor or the Agent, collections, rents or payments remitted to the Indemnity Provider or any agent or representative.

If a written demand is made against any Indemnified Person or if any proceeding shall be commenced against such Indemnified Person (including without limitation a written notice of such proceeding) for any Claim, such Indemnified Person shall promptly notify the Indemnity Provider in writing and shall not take action with respect to such Claim without the consent of the Indemnity Provider for thirty (30) days after the receipt of such notice by the Indemnity Provider; provided, however, that in the case of any such Claim, if action shall be required by law or regulation to be taken prior to the end of such period of thirty (30) days, such Indemnified Person shall endeavor to, in such notice to the Indemnity Provider, inform the Indemnity Provider of such shorter period, and no action shall be taken with respect to such Claim without the consent of the Indemnity Provider before seven (7) days before the end of such shorter period unless the Indemnified Person shall be required by such law or regulation to take action prior to the end of such seven (7) day period; provided, further, that the failure of such Indemnified Person to give the notices referred to in this sentence shall not diminish the Indemnity Provider’s obligation hereunder except to the extent such failure precludes the Indemnity Provider from contesting all or any part of such Claim, but only for the portion of the Claim that the Indemnity Provider is precluded from contesting.

If, within thirty (30) days of receipt of such notice from the Indemnified Person (or such shorter period as the Indemnified Person has notified the Indemnity Provider is required by law or regulation for the Indemnified Person to respond to such Claim), the Indemnity Provider shall request in writing that such Indemnified Person respond to such Claim, the Indemnified Person shall, at the reasonable expense of the Indemnity Provider, in good faith conduct and control such action (including without limitation by pursuit of appeals) (provided, however, that (A) if such Claim, in the Indemnity Provider’s reasonable discretion, can be pursued by the Indemnity Provider on behalf of or in the name of such Indemnified Person, the Indemnified Person, at the Indemnity Provider’s request, shall allow the Indemnity Provider to conduct and control the response to such Claim and (B) in the case of any Claim (and notwithstanding the provisions of the foregoing subsection (A)), the Indemnified Person may request in writing that the Indemnity Provider conduct and control the response to such Claim (with counsel to be selected by the Indemnity Provider and consented to by such Indemnified Person, such consent not to be unreasonably withheld or delayed; provided, however, that any Indemnified Person may retain separate counsel at the expense of the Indemnity Provider in the event of a potential conflict of interest between such Indemnified Person and the Indemnity Provider)) by, in the sole discretion of the Person conducting and controlling the response to such Claim (1) resisting payment thereof, (2) not paying the same except under protest, if protest is necessary and proper, (3) if the payment be made, using reasonable efforts to obtain a refund thereof in appropriate administrative and judicial proceedings, or (4) taking such other action as is reasonably requested by the Indemnity Provider from time to time.

The party controlling the response to any Claim shall consult in good faith with the non-controlling party and shall keep the non-controlling party reasonably informed as to the conduct of the response to such Claim; provided, that all decisions ultimately shall be made in the discretion of the controlling party. The parties agree that an Indemnified Person may at any time decline to take further action with respect to the response to such Claim and may settle such Claim if such Indemnified Person shall waive its rights to any indemnity from the Indemnity Provider that otherwise would be payable in respect of such Claim (and any future Claim, the pursuit of which is precluded by reason of such resolution of such Claim) and shall pay to the Indemnity Provider any amount previously paid or advanced by the Indemnity Provider pursuant to this Section 11.1 by way of indemnification or advance for the payment of an amount regarding such Claim, except reasonable expenses therefrom incurred by such Indemnified Person in connection with the response to such Claim.

Notwithstanding the foregoing provisions of this Section 11.1, an Indemnified Person shall not be required to take any action and the Indemnity Provider shall not be permitted to respond to any Claim in its own name or that of the Indemnified Person unless (A) the Indemnity Provider shall have agreed to pay and shall pay to such Indemnified Person on demand and on an After Tax Basis all reasonable costs, losses and expenses that such Indemnified Person actually incurs in connection with such Claim, including without limitation all reasonable legal, accounting and investigatory fees and disbursements and the Indemnity Provider shall have agreed that the Claim is an indemnifiable Claim hereunder, (B) the Indemnified Person shall have reasonably determined that the action to be taken will not result in any material danger of sale, forfeiture or loss of the Property, or any part thereof or interest therein, will not interfere with the payment of Rent, and will not result in risk of criminal liability, (C) if such Claim shall involve the payment of any amount prior to the resolution of such Claim, the Indemnity Provider shall provide to the Indemnified Person an interest-free advance in an amount equal to the amount that the Indemnified Person is required to pay (with no additional net after-tax cost to such Indemnified Person) prior to the date such payment is due, (D) in the case of an appeal of an adverse determination of a Claim that must be pursued in the name of an Indemnified Person (or an Affiliate thereof), the Indemnity Provider shall have provided to such Indemnified Person written advice, but not an opinion, of independent counsel selected by the Indemnity Provider and reasonably satisfactory to the Indemnified Person stating that the position asserted in such appeal will more likely than not prevail) and (E) no Event of Default by the Indemnity Provider shall have occurred and be continuing. In no event shall an Indemnified Person be required to appeal an adverse judicial determination to the United States Supreme Court. In addition, an Indemnified Person shall not be required to contest any Claim in its name (or that of an Affiliate) if the subject matter thereof shall be of a continuing nature and shall have previously been decided adversely to the position taken by the Indemnity Provider by a court of competent jurisdiction pursuant to the contest provisions of this Section 11.1, unless there shall have been a change in law (or interpretation thereof) and the Indemnified Person shall have received, at the Indemnity Provider’s expense, an opinion of independent counsel selected by the Indemnity Provider and reasonably acceptable to the Indemnified Person stating that as a result of such change in law (or interpretation thereof), it is more likely than not that the Indemnified Person will prevail in such contest. In no event shall the Indemnity Provider be permitted to adjust or settle any Claim without the consent of the Indemnified Person to the extent any such adjustment

or settlement involves, or is reasonably likely to involve, any performance by or adverse admission by or with respect to the Indemnified Person.

11.2. General Tax Indemnity.

(a) Subject to the limitations set forth in Section 11.7 hereof, the Indemnity Provider shall pay and assume liability for, and does hereby agree to indemnify, protect and defend the Property and all Indemnified Persons, and hold them harmless against, all Impositions on an After Tax Basis, and all payments pursuant to the Operative Agreements shall be made free and clear of and without deduction for any and all present and future Impositions.

(b) Notwithstanding anything to the contrary in Section 11.2(a) hereof, the following shall be excluded from the indemnity required by Section 11.2(a):

(i) Taxes (other than Taxes that are, or are in the nature of, sales, use, rental, value added, ad valorem, transfer or property taxes) that are imposed on a Indemnified Person by the United States federal government that are based on or measured by the net income (including without limitation taxes based on capital gains and minimum taxes) of such Person; provided, that this clause (i) shall not be interpreted to prevent a payment from being made on an After Tax Basis if such payment is otherwise required to be so made;

(ii) Taxes (other than Taxes that are, or are in the nature of, sales, use, rental, value added, ad valorem, transfer or property taxes) that are imposed on any Indemnified Person by any state or local jurisdiction or taxing authority within any state or local jurisdiction and that are based upon or measured by the net income (including without limitation taxes based on capital gains and minimum taxes) of such Person; provided that such Taxes shall not be excluded under this subparagraph (ii) to the extent such Taxes would have been imposed had the location, possession or use of the Property in, the location or the operation of the Lessee in, or the Lessee’s making payments under the Operative Agreements from, the jurisdiction imposing such Taxes been the sole connection between such Indemnified Person and the jurisdiction imposing such Taxes; provided, further, that this clause (ii) shall not be interpreted to prevent a payment from being made on an After Tax Basis if such payment is otherwise required to be so made;

(iii) any Tax to the extent it relates to any act, event or omission that occurs after the termination of the Lease and redelivery or sale of the Property in accordance with the terms of the Lease (but not any Tax that relates to such termination, redelivery or sale and/or to any period prior to such termination, redelivery or sale);

(iv) any Taxes which are imposed on an Indemnified Person as a result of the gross negligence or willful misconduct of such Indemnified Person itself, as

determined by a court of competent jurisdiction (as opposed to gross negligence or willful misconduct imputed to such Indemnified Person), but not Taxes imposed as a result of ordinary negligence of such Indemnified Person; and

(v) Impositions imposed or assessed by the PBGC on any Financing Party or on any pension plan (as defined in ERISA Section 3(2)) maintained by any Financing Party.

Notwithstanding the foregoing, the exclusions from the definition of “Impositions” set forth in clauses (i), (ii) and (iii) shall not apply (but the other exclusions shall apply) to any Taxes or increase in Taxes imposed on an Indemnified Person net of any decrease in Taxes realized by such Indemnified Person, to the extent that such tax increase or decrease would not have occurred if on each date of an Advance the Primary Financing Parties had advanced funds to the Lessee in the form of a loan secured by the Property in an amount equal to the Closing Date Advance and Construction Advances funded on such date of an Advance, with debt service equal to the Basic Rent payable on each Schedule Interest Payment Date and a principal balance at the maturity of such loan in an amount equal to the then outstanding amount of the Notes at the end of the term of the Lease.

(c) (i) Subject to the terms of Section 11.2(f) and 11.7, the Indemnity Provider shall pay or cause to be paid in a timely manner all Impositions directly to the taxing authorities where feasible and otherwise to the Indemnified Person, as appropriate, and the Indemnity Provider shall at its own expense, upon such Indemnified Person’s reasonable request, furnish to such Indemnified Person copies of official receipts or other satisfactory proof evidencing such payment.

(ii) In the case of Impositions for which no contest is conducted pursuant to Section 11.2(f) and which the Indemnity Provider pays directly to the taxing authorities, the Indemnity Provider shall pay such Impositions prior to the latest time permitted by the relevant taxing authority for timely payment. In the case of Impositions for which the Indemnity Provider reimburses an Indemnified Person, the Indemnity Provider shall do so within ten (10) days after receipt by the Indemnity Provider of demand by such Indemnified Person describing in reasonable detail the nature of the Imposition and the basis for the demand (including without limitation the computation of the amount payable), accompanied by receipts or other reasonable evidence of such demand. In the case of Impositions for which a contest is conducted pursuant to Section 11.2(f), the Indemnity Provider shall pay such Impositions or reimburse such Indemnified Person for such Impositions, to the extent not previously paid or reimbursed pursuant to subsection (a), prior to the latest time permitted by the relevant taxing authority for timely payment after conclusion of all contests under Section 11.2(f).

(iii) At the Indemnity Provider’s request, the amount of any indemnification payment by the Indemnity Provider pursuant to subsection (a)

shall be verified and certified by an independent public accounting firm mutually acceptable to the Indemnity Provider and the Indemnified Person. The fees and expenses of such independent public accounting firm shall be paid by the Indemnity Provider unless such verification shall result in an adjustment in the Indemnity Provider’s favor of ten percent (10%) or more of the payment as computed by the Indemnified Person, in which case such fee shall be paid by the Indemnified Person.

(d) The Indemnity Provider shall be responsible for preparing and filing any real and personal property or ad valorem tax returns in respect of the Property. In case any other report or tax return shall be required to be made with respect to any obligations of the Indemnity Provider under or arising out of subsection (a) and of which the Indemnity Provider has knowledge or should have knowledge, the Indemnity Provider, at its sole cost and expense, shall notify the relevant Indemnified Person of such requirement and (except if such Indemnified Person notifies the Indemnity Provider that such Indemnified Person intends to prepare and file such report or return) (A) to the extent required or permitted by and consistent with Legal Requirements, make and file in the Indemnity Provider’s name such return, statement or report; and (B) in the case of any other such return, statement or report required to be made in the name of such Indemnified Person, advise such Indemnified Person of such fact and prepare such return, statement or report for filing by such Indemnified Person or, where such return, statement or report shall be required to reflect items in addition to any obligations of the Indemnity Provider under or arising out of subsection (a), provide such Indemnified Person at the Indemnity Provider’s expense with information sufficient to permit such return, statement or report to be properly made with respect to any obligations of the Indemnity Provider under or arising out of subsection (a) no later than fifteen (15) days prior to the due date thereof. Such Indemnified Person shall, upon the Indemnity Provider’s request and at the Indemnity Provider’s expense, provide any data maintained by such Indemnified Person (and not otherwise available to or within the control of the Indemnity Provider) with respect to the Property which the Indemnity Provider may reasonably require to prepare any required tax returns or reports.

(e) As between the Indemnity Provider on one hand, and each Financing Party on the other hand, the Indemnity Provider shall be responsible for, and the Indemnity Provider shall indemnify and hold harmless each Financing Party (without duplication of any indemnification required by subsection (a)) on an After Tax Basis against, any obligation for United States or foreign withholding taxes or similar levies, imposts, charges, fees, deductions or withholdings (collectively, “Withholdings”) imposed in respect of the Interest payable on the Notes or with respect to any other payments under the Operative Agreements (all such payments being referred to herein as “Exempt Payments” to be made without deduction, withholding or setoff) (and, if any Financing Party receives a demand for such payment from any taxing authority or a Withholding is otherwise required with respect to any Exempt Payment, the Indemnity Provider shall discharge such demand on behalf of such Financing Party); provided, however, that the obligation of the Indemnity Provider under this Section 11.2(e) shall not apply to:

(i) Withholdings on any Exempt Payment to any Financing Party which is a non-U.S. Person unless such Financing Party is, on the date hereof (or on the date it becomes a Financing Party hereunder) and on the date of any change in the principal place of business or the lending office of such Financing Party, entitled to submit a Form W-8BEN or Form W-8ECI or successor applicable form, certifying in each case that such party is entitled under Section 1441 or 1442 of the Code or any other applicable provision thereof or under any applicable tax treaty or convention to receive payments pursuant to the Operative Agreements without deduction or withholding of United States federal income tax and is a foreign Person thereby entitled to an exemption from United States backup withholding taxes (except where the failure of the exemption results from a change in the principal place of business of the Lessee); provided, however, if a failure of the exemption is due to a change in law after the date hereof or in the case of a Financing Party that acquires its interest after the date hereof, a change in law occurring after such date, then the Indemnity Provider shall be liable for any withholding resulting therefrom; or

(ii) Any U.S. Taxes imposed solely by reason of the failure by a non-U.S. Person to comply with applicable certification, information, documentation or other reporting requirements concerning the nationality, residence, identity or connections with the United States of America of such non-U.S. Person if such compliance is required by statute or regulation of the United States of America as a precondition to relief or exemption from such U.S. Taxes if the Indemnity Provider has provided such certification, information, documentation or other reporting requirements to the Financing Party on a timely basis and the Financing Party is eligible for such relief or exemption.

For the purposes of this Section 11.2(e), (A) “U.S. Person” shall mean a citizen, national or resident of the United States of America, a corporation, partnership or other entity created or organized in or under any laws of the United States of America or any State thereof, or any estate or trust that is subject to Federal income taxation regardless of the source of its income, (B) “U.S. Taxes” shall mean any present or future tax, assessment or other charge or levy imposed by or on behalf of the United States of America or any taxing authority thereof or therein, (C) “Form W-8BEN” shall mean Form W-8BEN (Certificate of Foreign Status of Beneficial Owner for United States Withholding) of the Department of the Treasury of the United States of America and (D) “Form W-8ECI” shall mean Form W-8ECI (Certificate of Foreign Person’s Claim for Exemption from Withholding on Income Effectively Connected with the Conduct of a Trade or Business in the United States) of the Department of the Treasury of the United States of America (or in relation to either such Form such successor and related forms as may from time to time be adopted by the relevant taxing authorities of the United States of America to document a claim to which such Form relates). Each of the Forms referred to in the foregoing clauses (C) and (D) shall include such successor and related forms as may from time to time be adopted by the relevant taxing authorities of the United States of America to document a claim to which such Form relates.

If a Financing Party or an Affiliate with whom such Financing Party files a consolidated tax return (or equivalent) subsequently receives the benefit in any country of a tax credit or an allowance resulting from U.S. Taxes with respect to which it has received a payment of an additional amount under this Section 11.2(e), such Financing Party will pay to the Indemnity Provider such part of that benefit as in the opinion of such Financing Party will leave it (after such payment) in a position no more and no less favorable than it would have been in if no additional payment had been required to be paid, provided always that (i) such Financing Party will be the sole judge of the amount of any such benefit and of the date on which it is received, (ii) such Financing Party will have the absolute discretion as to the order and manner in which it employs or claims tax credits and allowances available to it and (iii) such Financing Party will not be obliged to disclose to the Borrower any information regarding its tax affairs or tax computations. A subsequent loss of such tax credit or allowance with respect to which a payment is made pursuant to this paragraph to an Indemnity Provider shall be treated as an Imposition that is indemnifiable under Section 11.2(a) hereof without regard to the exclusions of Section 11.2(b)(i), (ii), and (iii) hereof.

Each non-U.S. Person that shall become a Financing Party after the date hereof shall, upon the effectiveness of the related transfer or otherwise upon becoming a Financing Party hereunder, be required to provide all of the forms and statements referenced above or other evidences of exemption from Withholdings if the Indemnity Provider has provided such certification, information, documentation or other reporting requirements to the Financing Party and the Financing Party is eligible for such relief or exemption.

(f) If a written Claim is made against any Indemnified Person or if any proceeding shall be commenced against such Indemnified Person (including without limitation a written notice of such proceeding), for any Impositions, the provisions in Section 11.1 relating to notification and rights to contest shall apply; provided, however, that the Indemnity Provider shall have the right to conduct and control such contest only if such contest involves a Tax other than a Tax on net income of the Indemnified Person that can be pursued independently from any other proceeding involving a Tax liability of such Indemnified Person and the Indemnity Provider agrees to pay to such Indemnified Person on demand the Impositions which are the subject of such claim to the extent the contest is unsuccessful. The controlling party shall provide the non-controlling party with a copy of (or appropriate excerpts from) any reports or claims issued by the relevant auditing agents or taxing authority to the controlling party thereof, in connection with such claim or the contest thereof.

(g) The parties agree that any party to this Agreement (and each employee, representative, or other agent of such party) may disclose the tax aspects of the transactions contemplated by this Agreement and the structural aspects of these transactions as they relate to such tax aspects without limitation of any kind on such disclosure.

11.3. Increased Costs, Loan Adequacy; Illegality, etc.

(a) If either (i) the introduction of or any change (including, without limitation, any change by way of imposition or increase of reserve requirements) in or in the interpretation of any law, guideline, rule, directive, request or regulation or (ii) the compliance by a Financing Party or any Affiliate thereof (each of which, an “Affected Party”) with any law, regulation, rule, directive, guideline or request from any central bank or other Governmental Authority (whether or not having the force of law), including, without limitation, compliance by an Affected Party with any request or directive regarding loan adequacy or advance adequacy (A) shall subject an Affected Party to any Tax (except for Taxes on the overall net income of such Affected Party), duty or other charge with respect to a Loan, Lessor Advance, or any right to make Loans or Lessor Advances under the Operative Agreements, or on any payment made under the Operative Agreements or (B) shall impose, modify or deem applicable any reserve requirement (including, without limitation, any reserve requirement imposed by the Board of Governors of the Federal Reserve System, but excluding any reserve requirement, if any, included in the determination of the Interest or Lessor Yield), special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Affected Party or (C) shall impose any other condition affecting a Loan or a Lessor Advance or a Financing Party’s rights under the Operative Agreements, the result of which is to increase the cost to any Affected Party or to reduce the amount of any sum received or receivable by an Affected Party under the Operative Agreements, then within ten (10) days after demand by such Affected Party (which demand shall be accompanied by a statement setting forth the basis for such demand), the Lessee shall pay to such Affected Party such additional amount or amounts as will compensate such Affected Party for such additional or increased cost incurred or such reduction suffered.

(b) If either (i) the introduction of or any change in or in the interpretation of any law, guideline, rule, regulation, directive or request or (ii) compliance by any Affected Party with any law, guideline, rule, regulation, directive or request from any central bank or other Governmental Authority or agency (whether or not having the force of law), including without limitation compliance by an Affected Party with any request or directive regarding loan adequacy or advance adequacy, has or would have the effect of reducing the rate of return on the Loan or Lessor Advance of any Affected Party as a consequence of its obligations under the Operative Agreements or arising in connection therewith to a level below that which any such Affected Party could have achieved but for such introduction, change or compliance (taking into consideration the policies of such Affected Party with respect to loan adequacy or advance adequacy) by an amount deemed by such Affected Party to be material, then from time to time, within ten (10) days after demand by such Affected Party (which demand shall be accompanied by a statement setting forth the basis for such demand), the Lessee shall pay to such Affected Party such additional amount or amounts as will compensate such Affected Party for such reduction.

(d) In determining any amount provided for in this section, the Affected Party may use any reasonable averaging and attribution methods. Any Affected Party making a claim under this section shall submit to the Lessee a written description as to such additional or increased cost or reduction and the calculation thereof, which written description shall be conclusive absent demonstrable error.

(e) [Reserved].

(f) If a Financing Party shall notify the Agent that a Eurodollar Disruption Event as described in clause (a) of the definition of “Eurodollar Disruption Event” has occurred, the Agent shall in turn so notify the Lessee, whereupon all Loans in respect of which Interest accrues, and all Lessor Advances in respect of which Lessor Yield accrues, at the Eurodollar Rate shall immediately be converted into Loans or Lessor Advances, as the case may be, in respect of which Interest and Lessor Yield, respectively, accrues at the ABR.

(g) If any Affected Party requests compensation under Section 11.3, or the Lessee is required to pay any additional amount to any Affected Party or any Governmental Authority for the account of any Affected Party pursuant to Section 11.3, or if any Affected Party gives a notice pursuant to Section 11.3, then such Affected Party shall use reasonable efforts to designate a different funding office for funding or booking its Loans or Lessor Advances, as the case may be, or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Affected Party, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 11.3, in the future, or eliminate the need for the notice pursuant to Section 11.3, as applicable, and (ii) in each case, would not subject such Affected Party to any reimbursement cost or expense and would not otherwise be disadvantageous to such Affected Party. The Lessee hereby agrees to pay all reasonable costs and expenses incurred by any Affected Party in connection with any such designation or assignment.

11.4. Funding/Contribution Indemnity.

The Lessee agrees to indemnify and to hold each Financing Party harmless from any loss or reasonable expense (“Breakage Costs”) which such Financing Party may sustain or incur as a consequence of (a) any default by the Lessee in connection with the drawing of funds for the Advance, (b) any default by Lessee in making any prepayment after a notice thereof has been given in accordance with the provisions of the Operative Agreements or (c) the making of a voluntary (as a result of a Rent payment made by the Lessee under the Lease) or involuntary payment of any Loan or any Lessor Advance based on the Eurodollar Rate on a day which is not the last day of an Interest Period with respect thereto. Such indemnification shall be in an amount equal to the excess, if any, of (x) the amount of interest which would have accrued on the amount so paid, or not so borrowed, accepted, converted or continued for the period from the date of such payment or of such failure to borrow, accept, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, accept, convert or continue, the Interest Period that would have commenced on the date of such failure) in each case at the

applicable Eurodollar Rate plus the Applicable Percentage for the Loan or Lessor Advance for such Interest Period over (y) the amount of interest (as determined by such Financing Party in good faith in its reasonable discretion) which would have accrued to such Financing Party on such amount by reemploying such funds in loans of the same type and amount during the period from the date of payment or failure to borrow to the last day of the then applicable Interest Period (or, in the case of a failure to borrow, the Interest Period that would have commenced on the date of such failure).

Any Person required to maintain the confidentiality of information as provided in this Section 12.13 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such information as such Person would accord to its own confidential information.

12.14. Financial Reporting/Tax Characterization.

Lessee agrees to obtain advice from its own accountants and tax counsel regarding the financial reporting treatment and the tax characterization of the transactions described in the Operative Agreements.

FORM OF LOCAL COUNSEL LEGAL OPINION

____________, 2004

TO THOSE ON THE ATTACHED DISTRIBUTION LIST

Re: Lease Financing provided in favor of United Therapeutics Corporation

Dear Sirs:

We have acted as special counsel to United Therapeutics Corporation, a Delaware corporation, as the construction agent, the lessee and the ground lessor (“UTHR”), in connection with certain transactions contemplated by the Participation Agreement dated as of June 28, 2004 (the “Participation Agreement”), among UTHR, Wachovia Development Corporation, as the borrower and as the lessor (the “Borrower” or the “Lessor”, as applicable), the various banks and other financial institutions which are parties thereto from time to time, as the credit lenders (individually, a “Credit Lender” and collectively, the “Credit Lenders”), the various banks and other financial institutions which are parties thereto from time to time, as the mortgage lenders (individually, a “Mortgage Lender” and collectively, the “Mortgage Lenders”), and Wachovia Bank, National Association, as the agent for the Primary Financing Parties and respecting the Security Documents, as the agent for the Secured Parties (the “Agent”). This opinion is delivered pursuant to Section 5.3(j) of the Participation Agreement. All capitalized terms used herein, and not otherwise defined herein, shall have the meanings assigned thereto in Appendix A to the Participation Agreement.

In connection with the foregoing, we have examined originals, or copies certified to our satisfaction, of [identify and define for purposes of this opinion the applicable Operative Agreements, including without limitation the Lease Addendum, the Agency Agreement Addendum and each of the following required for filing in Maryland: the Mortgage Instrument, each related UCC Financing Statement, the Ground Lease, the Memorandum of Lease and the Memorandum of Ground Lease] and such other corporate documents, partnership documents and records of UTHR, certificates of public officials and representatives of UTHR as to certain factual matters, and such other instruments and documents which we have deemed necessary or advisable to examine for the purpose of this opinion. With respect to such examination, we have assumed (i) the statements of fact made in all such certificates, documents and instruments are true, accurate and complete; (ii) the due authorization, execution and delivery of the Operative Agreements by the parties thereto; (iii) the genuineness of all signatures, the authenticity and completeness of all documents, certificates, instruments, records, corporate records and partnership records submitted to us as originals and the conformity to the original instruments of all documents submitted to us as copies, and the authenticity and

B-1

completeness of the originals of such copies; (iv) that all parties have all requisite corporate power and authority or partnership power and authority, as applicable, to execute, deliver and perform the Operative Agreements; and (v) except as to UTHR, the enforceability of the Mortgage Instrument, the Ground Lease, the Memorandum of Agency Agreement, the Memorandum of Lease and the Memorandum of Ground Lease against all parties thereto.

Based on the foregoing, and having due regard for such legal considerations as we deem relevant, and subject to the limitations and assumptions set forth herein, including without limitation the matters set forth in the last two (2) paragraphs hereof, we are of the opinion that:

(a) Each of the Mortgage Instrument, the Ground Lease, the Memorandum of Agency Agreement, the Memorandum of Lease and the Memorandum of Ground Lease is enforceable in accordance with its respective terms, except as such is limited by laws generally affecting the enforcement of creditors’ rights, which laws will not materially prevent the realization of the benefits intended by such documents.

(b) The forms of the Mortgage Instrument and each UCC Financing Statement, attached hereto as Schedules 1 and 2, respectively, are in proper form for filing and recording with the offices of [identify the recording office of the county clerk where the Property in Maryland is to be located]. Upon filing of the Mortgage Instrument and each UCC Financing Statement in [identify the recording office of the county clerk where the Property in Maryland is to be located], the Agent will have a valid, perfected lien and security interest in that portion of the Collateral described in the Mortgage Instrument or any such UCC Financing Statement to the extent such Collateral is comprised of real property and/or fixtures.

(c) The forms of the Memorandum of Agency Agreement, the Memorandum of Lease and the Memorandum of Ground Lease, attached hereto as Schedules 3, 4 and 5, respectively, are in appropriate form for filing and recording with the [identify the recording office of the county clerk where the Property in Maryland is to be located].

(d) The Memorandum of Agency Agreement, when filed and recorded with the [identify the recording office of the county clerk where the Property in Maryland is to be located], will have been filed and recorded in all public offices in the State of Maryland in which filing or recording is necessary to provide constructive notice of the Agency Agreement to third Persons and to establish of record the interest of the Lessor and the Lessee thereunder as to the Property.

(e) The Memorandum of Lease, when filed and recorded with the [identify the recording office of the county clerk where the Property in Maryland is to be located], will have been filed and recorded in all public offices in the State of Maryland in which filing or recording is necessary to provide constructive notice of the Lease to third Persons and to establish of record the interest of the Lessor and the Lessee thereunder as to the Property.

(f) The Memorandum of Ground Lease, when filed and recorded with the [identify the recording office of the county clerk where the Property in Maryland is to be located], will have been filed and recorded in all public offices in the State of Maryland in which filing or

B-2

recording is necessary to provide constructive notice of the Ground Lease to third Persons and to establish of record the interest of the Ground Lessor and the Lessor, in its capacity as ground lessee thereunder, as to the Property.

(g) The execution and delivery by Wachovia Development Corporation of the Operative Agreements to which it is a party and compliance by Wachovia Development Corporation, as the Borrower, as the Lessor or as the ground lessee under the Ground Lease, as applicable, with all of the provisions thereof do not and will not contravene any law, rule or regulation of Maryland.

(h) By reason of their participation in the transaction contemplated under the Operative Agreements, none of the Agent, the Credit Lenders, the Mortgage Lenders, the Borrower, the Lessor or Wachovia Development Corporation, as the ground lessee under the Ground Lease, has to (i) qualify as a foreign corporation in Maryland, (ii) file any application or any designation for service of process in Maryland or (iii) pay any franchise, income, sales, excise, stamp or other taxes of any kind to Maryland.

(i) The provisions in the Operative Agreements concerning Rent, interest, fees, prepayment premiums and other similar charges do not violate the usury laws or other similar laws regulating the use or forbearance of money of Maryland.

(j) If the transactions contemplated by the Operative Agreements are characterized as a lease transaction by a court of competent jurisdiction, the Lease, including without limitation the Lease Supplement and the Lease Addendum, shall demise to the Lessee a valid leasehold interest in the Property.

(k) If the transactions contemplated by the Operative Agreements are characterized as a loan transaction by a court of competent jurisdiction, the combination of the Mortgage Instrument, the Agency Agreement, including without limitation the Agency Agreement Addendum and the Memorandum of Agency Agreement, the Lease, including without limitation the Lease Supplement, the Lease Addendum and the Memorandum of Lease, the Ground Lease, including without limitation the Memorandum of Ground Lease, and the other Operative Agreements incorporated in any of the foregoing by reference are sufficient to create a valid, perfected lien or security interest in the Property, enforceable as a deed of trust in Maryland.

This opinion is limited to the matters stated herein and no opinion is implied or may be inferred beyond the matters stated herein. This opinion is based on and is limited to the laws of the State of Maryland and the federal laws of the United States of America. Insofar as the foregoing opinion relates to matters of law other than the foregoing, no opinion is hereby given.

This opinion is for the sole benefit of UTHR, the Borrower, the Lessor, Wachovia Development Corporation, in its capacity as the ground lessee under the Ground Lease, the Credit Lenders, the Mortgage Lenders, the Agent and their respective successors and assigns and may not be relied upon by any other Person (other than such parties and their respective successors and assigns) without the express written consent of the undersigned. The opinions expressed herein are as of the date hereof and we make no undertaking to amend or supplement such opinions if facts come

B-3

to our attention or changes in the current law of the jurisdictions mentioned herein occur which could affect such opinions.


		Very truly yours,

FORM OF LEGAL OPINION FOR LESSOR

____________, 2004

TO THOSE ON THE ATTACHED DISTRIBUTION LIST


Re:		Lease Financing Provided in Favor of
		United Therapeutics Corporation

Ladies and Gentlemen:

We have acted as special counsel for Wachovia Development Corporation, a North Carolina corporation (“WDC”), in its capacity as borrower, lessor and ground lessee under the Participation Agreement dated as of June 28, 2004 (the “Participation Agreement”) by and among WDC, as the borrower and as the lessor, United Therapeutics Corporation, as the construction agent and as the lessee (the “Construction Agent” or the “Lessee”, as applicable), the various banks and other financial institutions which are parties thereto from time to time, as the credit lenders (individually, a “Credit Lender” and collectively, the “Credit Lenders”), the various banks and other financial institutions which are parties thereto from time to time, as the mortgage lenders (individually, a “Mortgage Lender” and collectively, the “Mortgage Lenders”), and Wachovia Bank, National Association, as the agent for the Primary Financing Parties and respecting the Security Documents, as the agent for the Secured Parties (the “Agent”). This opinion is delivered pursuant to Section 5.3(dd) of the Participation Agreement. All capitalized terms used herein, and not otherwise defined herein, shall have the meanings assigned thereto in Appendix A to the Participation Agreement.

In rendering the opinions expressed below, we have examined the following documents, each dated as of the date hereof unless otherwise noted (collectively, but excluding the Financing Statement (as defined below), the “Documents”):

1.		the Participation Agreement;

2.		the Credit Agreements;

3.		the Notes;

4.		the Agency Agreement;

5.		the Lease;

G-1

6.		the Ground Lease;

7.		the Security Agreement; and

8.		the Uniform Commercial Code financing statement attached as Schedule 1 hereto (the “Financing Statement”).

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such corporate records, certificates of public officials and representatives of WDC with respect to factual matters and such other instruments and documents as we have deemed necessary or advisable for the purpose of rendering this opinion.

With respect to such examination, we have assumed (a) that the statements of fact made in all such certificates, documents and instruments are true, accurate and complete; (b) the due authorization, execution and delivery of the Documents by all parties thereto other than WDC; (c) the genuineness of all signatures, the authenticity and completeness of all documents, certificates, instruments, records and corporate records submitted to us as originals and the conformity to the original instruments of all documents submitted to us as copies, and the authenticity and completeness of the originals of such copies, which facts we have not independently verified; (d) that any certificate or document upon which we have relied and which was given or dated earlier than the date of this letter continues to remain accurate, insofar as relevant to the opinions contained herein, from such earlier date through and including the date hereof; (e) that all parties other than WDC have all requisite power and authority to execute, deliver and perform the Documents; (f) the enforceability of the Documents against all parties thereto other than WDC in accordance with their respective terms; and (g) that if the Agent or any of the other Financing Parties seeks to enforce its rights under the Documents, such enforcement shall only be under circumstances which are consistent with applicable law and the provisions of the Documents.

Based upon the foregoing, and having due regard for such legal considerations as we deem relevant, and subject to the limitations and assumptions set forth herein, including without limitation the matters set forth in the last two (2) paragraphs hereof, we are of the opinion that:

1. WDC is a corporation validly existing under the laws of the State of North Carolina, and has the corporate power to execute, deliver and perform its obligations under the Documents.

2. The execution, delivery and performance by WDC of the Documents have been duly authorized by all necessary action on the part of WDC, and the Documents have been duly executed and delivered by WDC.

3. The execution and delivery by WDC of the Documents and compliance by WDC with all of the provisions thereof do not and will not contravene the provisions of its articles of incorporation or its bylaws.

G-2

4. If, notwithstanding any choice of law provision therein to the contrary, a court were to hold that the Documents, or any part thereof, are governed by, and to be construed in accordance with, the laws of the State of North Carolina, each of such Documents (or such part thereof) would be, under the laws of the State of North Carolina, the legal, valid and binding obligation of WDC, enforceable against WDC in accordance with the terms thereof, subject to the following qualifications:

(a) enforceability may be limited by any applicable bankruptcy, insolvency, reorganization, fraudulent transfer, moratorium or similar laws affecting the enforcement of creditors’ rights generally;

(b) enforceability may be limited by general principles of equity (regardless of whether considered in a proceeding in equity or at law) including, without limitation, application by a court of competent jurisdiction of principles of good faith, fair dealing, commercial reasonableness, materiality, unconscionability, and conflict with public policy and other similar principles;

(c) we express no opinion as to whether the transactions contemplated by the Documents and the other Operative Agreements will be characterized as a lease or a financing arrangement or the effect that such characterization may have on the enforceability of particular provisions of the Documents and the other Operative Agreements that are inconsistent with the characterization given to the Documents and the other Operative Agreements;

(d) the enforceability and availability of certain remedies, rights and waiver provisions may be limited or rendered ineffective by applicable law, although the inclusion of such provisions does not affect the validity or lien of any Document as a whole, and there exist legally adequate remedies for the realization of the principal benefits afforded thereby;

(e) we express no opinion as to the effectiveness of any provision of the Documents whereby any party waives procedural, substantive or constitutional rights which are forbidden by law to be waived or if such a waiver is determined to be against public policy;

(f) we call to your attention that N.C. Gen. Stat. §6-21.2 sets forth the procedures and limitations applicable to the collection of attorneys’ fees and, accordingly, any provision in the Documents relating to the ability to collect attorneys’ fees upon default are subject to those limitations;

(g) we call to your attention that N.C. Gen. Stat. §22B-10 provides that any waiver of the right to trial by jury is unenforceable;

(h) we express no opinion as to the enforceability of any provision of the Documents denying the holder of any lien inferior to the liens created by the Documents the ability to require the Financing Parties to marshal assets;

G-3

(i) we express no opinion as to the right to obtain a receiver, which determination is subject to equitable principles;

(j) we express no opinion with respect to any provision of the Documents providing that the acceptance by the Financing Parties of a past due installment or other performance by a party shall not be deemed a waiver of their right to accelerate the loan or other payment obligation. A North Carolina Court of Appeals has held that when the holder of a promissory note regularly accepted late payments, it is deemed to have waived its right to accelerate the debt because of late payments until it notifies the maker that prompt payments are again required. See, Driftwood Manor Investors v. City Federal Savings & Loan Association, 63 N.C. App. 459, 305 S.E. 2d 204 (1983);

(k) we express no opinion with respect to any provision of the Documents which requires that any amendments or waivers to the Documents must be in writing;

(l) we express no opinion as to the enforceability of any provisions of the Documents which purport to define and treat certain items and materials now or hereafter located on the real property encumbered by the Documents as “fixtures” or part of the “improvements.” Under N.C. Gen. Stat. § 25-9-102, an item is a “fixture” when it becomes “so related to particular real estate” that an interest in that item arises under real estate law. We are aware of no law or decision that permits the parties to a secured transaction to agree that an item that is not otherwise a fixture shall be treated as a fixture;

(m) we express no opinion as to the enforceability of any provision of the Documents which directs the application of sale proceeds other than as required by N.C. Gen. Stat. § 45-21.31 et seq., or N.C. Gen. Stat. § 25-9-615;

(n) we express no opinion as to any liquidated damages provision;

(o) we express no opinion with respect to any consent to venue, jurisdiction or service of process provisions; and

(p) we express no opinion as to any choice of law provision.

5. The execution and delivery by WDC of the Documents and compliance by WDC with all of the provisions thereof do not and will not, considering Laws customarily applicable to transactions of this type, contravene any North Carolina or federal Laws.

6. Other than filing the Financing Statement as described in Paragraphs 7 and 8 of this opinion, no Governmental Action by, and no notice to or filing with, any North Carolina or federal Governmental Authority is required as of the date hereof for the due

G-4

execution, delivery or performance by WDC of any of the Documents. No fees, taxes or other charges are payable to any North Carolina or federal Governmental Authority as of the date hereof for the due execution, delivery or performance by WDC of any of the Documents, except that routine filing fees are payable in connection with filing of the Financing Statement.

7. Assuming that the Financing Statement gives the correct names and the mailing addresses of WDC and the Agent, and gives the correct type of organization of WDC, the jurisdiction of organization of WDC and the organizational identification number of WDC, the Financing Statement is in appropriate form for filing with the North Carolina Secretary of State.

8. Assuming that (i) value has been given, (ii) WDC has rights in the Security Assets (as defined in the Security Agreement), (iii) the Financing Statement has been properly filed with, and accepted for filing by, the North Carolina Secretary of State, (iv) the filing fees in connection with such filing have been paid, (v) the Financing Statement gives the correct names and mailing addresses of WDC and the Agent, gives the correct type of organization of WDC, the jurisdiction of organization of WDC and the organizational identification number of WDC, the Agent will have a perfected security interest in the Security Assets to the extent that (i) a security interest may be perfected by the filing of a financing statement in North Carolina under Article 9 of the Uniform Commercial Code as enacted in North Carolina (the “UCC”) and (ii) the Security Assets are described in the Financing Statement.

We call to your attention that perfection or nonperfection of the security interest in the Security Assets may be subject to the following qualifications:

(a) in the case of property which becomes Security Assets after the date hereof, (i) section 552 of the United States Bankruptcy Code (Title 11 United States Code) limits the extent to which property acquired by a debtor after the commencement of a case under the United States Bankruptcy Code may be subject to a security interest arising under a security agreement entered into by the debtor before the commencement of such case, and (ii) any security interest therein is subject to the provisions of Section 9-204 of the UCC;

(b) Section 9-515 of the UCC requires the filing of continuation statements within six months prior to the expiration of each consecutive five-year period beginning on the date of the original filings in order to maintain the effectiveness of the Financing Statement;

(c) in the case of proceeds, continuation of perfection of the security interests therein is limited as set forth in § 9-315 of the UCC;

(d) Section 9-311 of the UCC provides that the filing of a financing statement under Article 9 of the UCC is not necessary or effective to perfect a security interest in collateral subject to (i) a statute, regulation, or treaty of the

X-0

Xxxxxx Xxxxxx whose requirements for a security interest’s obtaining priority over the rights of a lien creditor with respect to the collateral preempt § 9-310(a) of the UCC, (ii) a certificate of title statute of North Carolina covering automobiles or other goods that provide for a security interest to be indicated on the certificate as a condition to or result of perfection of the security interest (except that the filing provisions of Article 9 of the UCC do apply to a security interest in such property during any period in which such property is inventory held for sale or lease by a person, or is leased by that person as lessor, and that person is in the business of selling goods of that kind, which security interest was created by such person as debtor), or (iii) a certificate of title statute of a jurisdiction other than North Carolina which provides for a security interest to be indicated on the certificate as a condition or result of the security interest’s obtaining priority over the rights of a lien creditor with respect to the property;

(e) Section 9-312 of the UCC provides that a security interest in deposit accounts, letter of credit rights, and money may be perfected only as specified in such section;

(f) the perfection of the security interest will be terminated as to any Security Assets acquired by the debtor more than four (4) months after the debtor so changes its name so as to make the Financing Statement seriously misleading, unless amendments to the Financing Statement which render the Financing Statement not seriously misleading are properly filed before the expiration of such four (4) months;

(g) we express no opinion with respect to the creation or perfection, of a security interest in any “commercial tort claim,” as defined in §9-102 of the UCC;

(h) the applicable provisions of Section 9-109 of the UCC provide that Article 9 of the UCC does not apply to collateral of the types described therein;

(i) the applicable provisions of Sections 9-301 through 9-307, and Section 9-316, of the UCC specify which jurisdiction’s laws govern the perfection of a security interest, and we express no opinion as to any security interest the perfection of which is not governed by the laws of North Carolina;

(j) we express no opinion with respect to any of the Security Assets that consist of fixtures, as-extracted collateral or timber to be cut; and

(k) we express no opinion as to the perfection of any security interest that may not be perfected by filing of a financing statement in North Carolina under Article 9 of the UCC.

9. WDC is not an “investment company” under the Investment Company Act of 1940, as amended.

G-6

The foregoing opinions are subject to the following additional assumptions, exceptions and qualifications:

A.

FORM OF LEGAL OPINION FOR LESSEE

____________, 2004

TO THOSE ON THE ATTACHED DISTRIBUTION LIST

Re: Lease Financing Provided in favor of United Therapeutics Corporation

Dear Sirs:

We have acted as special counsel to United Therapeutics Corporation, a Delaware corporation (“UTHR”), as the construction agent, the lessee and the ground lessor, in connection with certain transactions contemplated by the Participation Agreement dated as of June 28, 2004 (the “Participation Agreement”), among UTHR, as the construction agent and as the lessee, Wachovia Development Corporation, as the borrower and as the lessor (the “Borrower” or the “Lessor”, as applicable), the various banks and other financial institutions which are parties thereto from time to time, as the credit lenders (individually, a “Credit Lender” and collectively, the “Credit Lenders”), the various banks and other financial institutions which are parties thereto from time to time, as the mortgage lenders (individually, a “Mortgage Lender” and collectively, the “Mortgage Lenders”), and Wachovia Bank, National Association, as the agent for the Primary Financing Parties and respecting the Security Documents, as the agent for the Secured Parties (the “Agent”). This opinion is delivered pursuant to Section 5.3(ee) of the Participation Agreement. All capitalized terms used herein, and not otherwise defined herein, shall have the meanings assigned thereto in Appendix A to the Participation Agreement.

In connection with the foregoing, we have examined originals, or copies certified to our satisfaction, of the Operative Agreements, and such other corporate, partnership or limited liability company documents and records of UTHR, certificates of public officials and representatives of UTHR as to certain factual matters, and such other instruments and documents which we have deemed necessary or advisable to examine for the purpose of this opinion. With respect to such examination, we have assumed (i) the statements of fact made in all such certificates, documents and instruments are true, accurate and complete; (ii) the due authorization, execution and delivery of the Operative Agreements by the parties thereto other than UTHR; (iii) the genuineness of all signatures (other than the signatures of persons signing on behalf of UTHR), the authenticity and completeness of all documents, certificates, instruments, records and corporate records submitted to us as originals and the conformity to the original instruments of all documents submitted to us as copies, and the authenticity and completeness of the originals of such copies; (iv) that all parties other than UTHR have all requisite corporate power and authority to execute, deliver and perform the Operative

H-1

Agreements; and (v) the enforceability of the Operative Agreements against all parties thereto other than UTHR.

(a) UTHR is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has the power and authority to conduct its business as presently conducted and to execute, deliver and perform its obligations under the Operative Agreements to which it is a party. UTHR is duly qualified to do business in all jurisdictions in which its failure to so qualify would materially impair its ability to perform its obligations under the Operative Agreements to which it is a party or its financial position or its business as now and now proposed to be conducted.

(b) The execution, delivery and performance by UTHR of the Operative Agreements to which it is a party have been duly authorized by all necessary corporate action on the part of UTHR and the Operative Agreements to which UTHR is a party have been duly executed and delivered by UTHR.

(c) The Operative Agreements to which UTHR is a party constitute valid and binding obligations of UTHR enforceable against UTHR in accordance with the terms thereof, subject to bankruptcy, insolvency, liquidation, reorganization, fraudulent conveyance, and similar laws affecting creditors’ rights generally, and general principles of equity (regardless of whether the application of such principles is considered in a proceeding in equity or at law).

(d) The execution and delivery by UTHR of the Operative Agreements to which it is a party and compliance by UTHR with all of the provisions thereof do not and will not (i) contravene the provisions of, or result in any breach of or constitute any default under, or result in the creation of any Lien (other than Permitted Liens) upon any of its property under or require the consent of any party which has not been obtained, under or with respect to its Articles of Incorporation By-Laws, or any indenture, mortgage, chattel mortgage, deed of trust, lease, conditional sales contract, bank loan or credit agreement or other agreement or instrument to which UTHR is a party or by which it or any of its property may be bound or affected, or (ii) contravene any Laws or any order of any Governmental Authority applicable to or binding on UTHR.

(e) No Governmental Action by, and no notice to or filing with, any Governmental Authority is required for the due execution, delivery or performance by UTHR of any of the Operative Agreements to which it is a party or for the acquisition, ownership, construction and completion of the Property, except for (i) those which have been obtained and (ii) application for and issuance of building permits and certificates of occupancy for the improvements to be constructed on the Property.

(f) Except as set forth on Schedule 1 hereto, there are no actions, suits or proceedings pending or to our knowledge, threatened against UTHR in any court or before any Governmental

H-2

Authority, that concern the Property or UTHR’s interest therein or that question the validity or enforceability of any Operative Agreement to which UTHR is a party or the overall transaction described in the Operative Agreements to which UTHR is a party.

(g) The Security Documents (other than the Mortgage Instrument which is addressed in a separate opinion issued as of the date of this opinion and other than the Liquid Collateral Agreements which are addressed in opinion (i) below) which have been executed and delivered as of the date of this opinion create, for the benefit of the Agent, the security interests in the Collateral described therein which by their terms such Security Documents purport to create. Upon filing of the UCC-1 financing statements (attached hereto as Schedule 2) relating to the Security Documents (other than the Mortgage Instrument which is addressed in a separate opinion issued as of the date of this opinion and other than the Liquid Collateral Agreements which are addressed in opinion (i) below) and in the recording offices specified in Schedule 2, the Agent will have a valid, perfected lien and security interest in that portion of the Collateral which can be perfected by the filing of UCC-1 financing statements under Article 9 of the UCC in [identify the state].

(h) The offer, issuance, sale and delivery of the Notes under the circumstances contemplated by the Participation Agreement do not, under existing law, require registration of the Notes being issued on the date hereof under the Securities Act of 1933, as amended.

(i) The Liquid Collateral Agreements are in a form sufficient to create in favor of the Agent for the benefit of the Secured Parties a valid, perfected security interest in all right, title and interest of UTHR in the Liquid Collateral delivered to the Intermediary and held in the Liquid Collateral Account.

This opinion is limited to the matters stated herein and no opinion is implied or may be inferred beyond the matters stated herein. This opinion is based on and is limited to the laws of the States of [ ], and the federal laws of the United States of America. Insofar as the foregoing opinion relates to matters of law other than the foregoing, no opinion is hereby given.
