WARRANTIES, REPRESENTATIONS AND COVENANTS

Mortgagor warrants, represents and covenants to Mortgagee as follows:

Section 3.1 Title to Mortgaged Property and Lien of this Instrument. Mortgagor (i) has good and indefeasible title to the Mortgaged Property, in fee simple (to the extent that the Mortgaged Property constitutes real property), free and clear of any liens, claims or interests, except for the Permitted Liens and the Priority Liens, and (ii) has full power and lawful authority to encumber the Mortgaged Property in the manner and form set forth in this Mortgage. This Mortgage creates a valid, enforceable second priority lien and security interest against the Mortgaged Property (subject only to the Permitted Liens and the Priority Liens).

Section 3.2 Lien Status. Mortgagor shall preserve and protect the lien and security interest status of this Mortgage and the other Note Documents. If any lien or security interest, other than the Permitted Liens or the Priority Liens, is asserted against the Mortgaged Property, Mortgagor shall promptly, and at its expense, (a) give Mortgagee a detailed written notice of such lien or security interest (including origin, amount and other terms), and (b) pay the underlying claim in full or take such other action so as to cause it to be released or contest the same in compliance with the requirements of the Indenture (including the requirement of providing a bond or other security satisfactory to Mortgagee).

Section 3.3 Payment and Performance. Mortgagor shall pay the Indebtedness when due under the Indenture, the Notes and the other Note Documents and shall perform the Obligations in full when they are required to be performed.

Section 3.4 Replacement of Fixtures. Mortgagor shall not, without the prior written consent of Mortgagee, permit any of the Fixtures to be removed at any time from the Land or Improvements, unless the removed item is removed temporarily for maintenance and repair or, if removed permanently, is obsolete and is replaced by an article of equal or better suitability and value, owned by Mortgagor subject to the liens and security interests of this Mortgage, the Intercreditor Agreement and the other Note Documents, and free and clear of any other lien or security interest except such as may be permitted under the Indenture or first approved in writing by Mortgagee.

Section 3.5 Inspection. Mortgagor shall permit Mortgagee and its agents, representatives and employees to inspect the Mortgaged Property and all books and records of Mortgagor located thereon. Provided that no Event of Default exists, all such inspection shall be conducted at reasonable times and upon reasonable prior notice to Mortgagor. Mortgagee shall restore the Mortgaged Property to the condition it was in immediately prior to such testing and investigation.

Section 3.6 Other Covenants. All of the covenants in the Indenture, the Intercreditor Agreement and the other Note Documents are incorporated herein by reference and, together with covenants in this Article 3, shall, to the extent applicable, be covenants running with the land.

Section 3.7 Condemnation Awards and Insurance Proceeds.

(a) Condemnation Awards. Mortgagor, immediately upon obtaining knowledge of the institution of any proceedings for the condemnation of the Mortgaged Property or any portion thereof, will notify Mortgagee of the pendency of such proceedings. Mortgagee may participate in any such proceedings and Mortgagor from time to time will deliver to Mortgagee all instruments requested by it to permit such participation. Unless otherwise permitted to be retained by Mortgagor under the Indenture, Mortgagor assigns, subject to the terms of the Intercreditor Agreement, all awards and compensation to which it is entitled for any condemnation or other taking, or any purchase in lieu thereof, to Mortgagee and authorizes Mortgagee to collect and receive such awards and compensation and to give proper receipts and acquittances therefore, subject to the terms of the Indenture. Unless otherwise permitted to be retained by Mortgagor under the Indenture, Mortgagor hereby waives all rights to such awards and compensation described in the foregoing sentence. Mortgagor, upon the reasonable request by Mortgagee, shall make, execute and deliver any and all instruments requested for the purpose of confirming the assignment of the aforesaid awards and compensation to Mortgagee free and clear of any liens, charges or encumbrances of any kind or nature whatsoever.

Section 3.8 Costs of Defending and Upholding the Lien. If any action or proceeding is commenced to which action or proceeding Mortgagee is made a party or in which it becomes necessary for Mortgagee to defend or uphold the lien of this Mortgage including any extensions, renewals, amendments or modifications thereof, Mortgagor shall, on demand, reimburse Mortgagee for all expenses (including, without limitation, reasonable attorneys' fees and reasonable appellate attorneys' fees) incurred by Mortgagee in any such action or proceeding and all such expenses shall be secured by this Mortgage. In any action or proceeding to foreclose this Mortgage or to recover or collect the Indebtedness, the provisions of law relating to the recovering of costs, disbursements and allowances shall prevail unaffected by this covenant.

Section 3.10 Security Deposits. To the extent required by law, or after an Event of Default has occurred and during its continuance, if required by Mortgagee, all security deposits of tenants of the Mortgaged Property shall be treated as trust funds not to be commingled with any other funds of Mortgagor. Within twenty (20) days after request by Mortgagee, Mortgagor shall furnish satisfactory evidence of compliance with this Section 3.10, as necessary, together with a statement of all security deposits deposited by the tenants and copies of all Leases not theretofore delivered to Mortgagee, as requested thereby, certified by Mortgagor.

(a) an "Event of Default" (as such term is defined in the Indenture) shall have occurred;

(b) Mortgagor's breach of any of the covenants set forth in this Mortgage and such failure continues for a period of ten (10) Business Days; or

ARTICLE 5
REMEDIES AND FORECLOSURE

Section 5.1 Remedies. If an Event of Default exists, Mortgagee may, at Mortgagee's election, and subject to the terms of the Intercreditor Agreement, exercise any or all of the following rights, remedies and recourses:

(a) To the extent permitted under the Indenture, the Intercreditor Agreement or any other Note Document, declare the Indebtedness to be immediately due and payable, without further notice, presentment, protest, notice of intent to accelerate, notice of acceleration, demand or action of any nature whatsoever (each of which hereby is expressly waived by Mortgagor), whereupon the same shall become immediately due and payable.

(b) Notify all tenants of the Premises and all others obligated on leases of any part of the Premises that all rents and other sums owing on leases have been assigned to Mortgagee and are to be paid directly to Mortgagee, and to enforce payment of all obligations owing on leases, by suit, ejectment, cancellation, releasing, reletting or otherwise, whether or not Mortgagee has taken possession of the Premises, and to exercise whatever rights and remedies Mortgagee may have under any assignment of rents and leases.

(c) As and to the extent permitted by law, enter the Mortgaged Property, either personally or by its agents, nominees or attorneys, and take exclusive possession thereof and thereupon, Mortgagee may (i) use, operate, manage, control, insure, maintain, repair, restore and otherwise deal with all and every part of the Premises and conduct business thereat; (ii) complete any construction on the Premises in such manner and form as Mortgagee deems advisable in the reasonable exercise of its judgment; (iii) exercise all rights and power of Mortgagor with respect to the Premises, whether in the name of Mortgagor, or otherwise, including, without limitation, the right to make, cancel, enforce or modify leases, obtain and evict tenants, and demand, sue for, collect and receive all earnings, revenues, rents, issues, profits and other income of the Premises and every part thereof, which rights shall not be in limitation of Mortgagee's rights under any assignment of rents and leases securing the Indebtedness; and (iv) pursuant to the provisions of the Indenture and the Intercreditor Agreement, apply the receipts from the Premises to the payment of the Indebtedness, after deducting therefrom all expenses (including attorneys' fees) incurred in connection with the aforesaid operations and all amounts necessary to pay the taxes, assessments, insurance and other charges in connection with the Mortgaged Property, as well as just and reasonable compensation for the services of Mortgagee, its counsel, agents and employees.

(d) Hold, lease, develop, manage, operate or otherwise use the Mortgaged Property upon such terms and conditions as Mortgagee may deem reasonable under the circumstances (making such repairs, alterations, additions and improvements and taking other actions, from time to time, as Mortgagee deems necessary or desirable), and apply all Rents and other amounts collected by Mortgagee in connection therewith in accordance with the provisions of Section 5.7 hereof.

(e) Require Mortgagor to assemble any collateral under the UCC of the State of Oklahoma, 12A 0.5. §§ 1-101 et seq. and make it available to Mortgagee, at Mortgagor's sole risk and expense, at a place or places to be designated by Mortgagee, in its sole discretion.

(f) Institute proceedings for the complete foreclosure of this Mortgage, either by judicial action or by power of sale, in which case the Mortgaged Property may be sold for cash or credit in accordance with applicable law in one or more parcels as Mortgagee may determine. Except as otherwise required by applicable law, with respect to any notices required or permitted under the UCC of the State of Oklahoma, Mortgagor agrees that ten (10) days' prior written notice shall be deemed commercially reasonable. At any such sale by virtue of any judicial proceedings, power of sale, or any other legal right, remedy or recourse, the title to and right of possession of any such

property shall pass to the purchaser thereof, and to the fullest extent permitted by law, Mortgagor shall be completely and irrevocably divested of all of its right, title, interest, claim, equity, equity of redemption, and demand whatsoever, either at law or in equity, in and to the property sold and such sale shall be a perpetual bar both at law and in equity against Mortgagor, and against all other Persons claiming or to claim the property sold or any part thereof, by, through or under Mortgagor. Mortgagee or any of the holders of the Notes may be a purchaser at such sale. If Mortgagee is the highest bidder, Mortgagee may credit the portion of the purchase price that would be distributed to Mortgagee against the Indebtedness in lieu of paying cash. In the event this Mortgage is foreclosed by judicial action, appraisement and valuation of the Mortgaged Property is waived. In the event of any sale made under or by virtue of this Article 5 (whether made by virtue of judicial proceedings or of a judgment or decree of foreclosure and sale) the entire Indebtedness, if not previously due and payable, immediately thereupon shall become due and payable. The failure to make any such tenants of the Premises party to any such foreclosure proceedings and to foreclose their rights will not be, nor be asserted to be by Mortgagor, a defense to any proceedings instituted by Mortgagee to collect the sums secured hereby.

(g) With or without entry, to the extent permitted and pursuant to the procedures provided by applicable law, institute proceedings for the partial foreclosure of this Mortgage for the portion of the Indebtedness then due and payable (if Mortgagee shall have elected not to declare the entire Indebtedness to be immediately due and owing), subject to the continuing lien of this Mortgage for the balance of the Indebtedness not then due; or (1) as and to the extent permitted by law, sell for cash or upon credit the Mortgaged Property or any part thereof and all estate, claim, demand, right, title and interest of Mortgagor therein, pursuant to power of sale or otherwise, at one or more sales, as an entity or in parcels, at such time and place, upon such terms and after such notice thereof as may be required or permitted by law, and in the event of a sale, by foreclosure or otherwise, of less than all of the Mortgaged Property, this Mortgage shall continue as a lien on the remaining portion of the Mortgaged Property; or (2) institute an action, suit or proceeding in equity for the specific performance of any covenant, condition or agreement contained herein or in any other Note Document; or (3) to the extent permitted by applicable law, recover judgment on the Indenture either before, during or after any proceedings for the enforcement of this Mortgage.

(h) Make application to a court of competent jurisdiction for, and obtain from such court as a matter of strict right and without notice to Mortgagor or regard to the adequacy of the Mortgaged Property for the repayment of the Indebtedness, the appointment of a receiver of the Mortgaged Property, and Mortgagor irrevocably consents to such appointment. Any such receiver shall have all the usual powers and duties of receivers in similar cases, including the full power to rent, maintain and otherwise operate the Mortgaged Property upon such terms as may be approved by the court, and shall apply such Rents in accordance with the provisions of Section 5.7 hereof.

(i) Exercise all other rights, remedies and recourses granted under the Indenture, the Intercreditor Agreement or the other Note Documents or otherwise available at law or in equity.

Section 5.2 Separate Sales. The Mortgaged Property may be sold in one or more parcels and in such manner and order as Mortgagee in its sole discretion may elect; the right of sale arising out of any Event of Default shall not be exhausted by any one or more sales.

Section 5.3 Remedies Cumulative, Concurrent and Nonexclusive. Mortgagee shall have all rights, remedies and recourses granted in this Mortgage, the Indenture, the Intercreditor Agreement or any of the other Note Documents and available at law or equity (including the UCC), which rights (a) shall be cumulated and concurrent, (b) may be pursued separately, successively or concurrently against Mortgagor or others obligated under the Indenture, the Intercreditor Agreement or the other Note

Documents, or against the Mortgaged Property, or against any one or more of them, at the sole discretion of Mortgagee, (c) may be exercised as often as occasion therefor shall arise, and the exercise or failure to exercise any of them shall not be construed as a waiver or release thereof or of any other right, remedy or recourse, and (d) are intended to be, and shall be, nonexclusive. No action by Mortgagee in the enforcement of any rights, remedies or recourses under the Indenture, the Intercreditor Agreement and the other Note Documents or otherwise at law or equity shall be deemed to cure any Event of Default.

Section 5.4 Release of and Resort to Collateral. Mortgagee may release, regardless of consideration and without the necessity for any notice to or consent by the holder of any subordinate lien on the Mortgaged Property, any part of the Mortgaged Property without, as to the remainder, in any way impairing, affecting, subordinating or releasing the lien or security interest created in or evidenced by the Note Documents or their status as a second lien and security interest in and to the Mortgaged Property. For payment of the Indebtedness, Mortgagee may resort to any other security in such order and manner as Mortgagee may elect.

Section 5.5 Waiver of Redemption, Notice and Marshalling of Assets. To the fullest extent permitted by law, Mortgagor hereby irrevocably and unconditionally waives and releases (a) all benefit that might accrue to Mortgagor by virtue of any present or future statute of limitations or law or judicial decision exempting the Mortgaged Property from attachment, levy or sale on execution or providing for any stay of execution, exemption from civil process, redemption or extension of time for payment, (b) unless otherwise required under the Indenture, the Intercreditor Agreement or any of the other Note Documents, all notices of any Event of Default or of any election by Mortgagee to exercise or the actual exercise of any right, remedy or recourse provided for under the Note Documents, and (c) any right to a marshalling of assets or a sale in inverse order of alienation.

Section 5.6 Discontinuance of Proceedings. If Mortgagee shall have proceeded to invoke any right, remedy or recourse permitted under the Note Documents and shall thereafter elect to discontinue or abandon it for any reason, Mortgagee shall have the unqualified right to do so and, in such an event, Mortgagor and Mortgagee shall be restored to their former positions with respect to the Indebtedness, the Obligations, the Note Documents, the Mortgaged Property and otherwise, and the rights, remedies, recourses and powers of Mortgagee shall continue as if the right, remedy or recourse had never been invoked, but no such discontinuance or abandonment shall waive any Event of Default which may then exist or the right of Mortgagee thereafter to exercise any right, remedy or recourse under the Note Documents for such Event of Default.

Section 5.7 Application of Proceeds. Subject to the Intercreditor Agreement, the proceeds of any sale made under or by virtue of this Article 5, together with any Rents and other amounts generated by the holding, leasing, management, operation or other use of the Mortgaged Property, shall be applied by Mortgagee (or the receiver, if one is appointed) in the following order unless otherwise required by applicable law:

(a) to the payment of the costs and expenses of taking possession of the Mortgaged Property and of holding, using, leasing, repairing, improving and selling the same, including, without limitation (1) Mortgagee's and receiver's fees and expenses, including the repayment of the amounts evidenced by any receiver's certificates, (2) court costs, (3) reasonable attorneys' and accountants' fees and expenses, and (4) costs of advertisement;

(b) to the payment of the Indebtedness and performance of the Obligations in such manner and order of preference as set forth in the Indenture; and

Section 5.8 Occupancy After Foreclosure. Except as otherwise required by applicable law, any sale of the Mortgaged Property or any part thereof in accordance with Section 5.1(e) or Section 5.1(f) hereof will divest all right, title and interest of Mortgagor in and to the property sold. Subject to applicable law, any purchaser at a foreclosure sale will receive immediate possession of the property purchased. If Mortgagor retains possession of such property or any part thereof subsequent to such sale, Mortgagor will be considered a tenant at sufferance of the purchaser, and will, if Mortgagor remains in possession after demand to remove, be subject to eviction and removal, forcible or otherwise, with or without process of law.

Section 5.9 Additional Advances and Disbursements; Costs of Enforcement.

(a) If any Event of Default exists, Mortgagee shall have the right, but not the obligation, to cure such Event of Default in the name and on behalf of Mortgagor. All sums advanced and expenses incurred at any time by Mortgagee under this Section 5.9, or otherwise under this Mortgage, the Indenture, the Intercreditor Agreement or any of the other Note Documents or applicable law, shall bear interest from the date that such sum is advanced or expense incurred, to and including the date of reimbursement, computed at the rate or rates at which interest is then computed on the Indebtedness, and all such sums, together with interest thereon, shall be secured by this Mortgage.

(b) Mortgagor shall pay all expenses (including reasonable attorneys' fees and expenses and all reasonable costs and expenses related to legal work, research and litigation) of or incidental to the perfection and enforcement of this Mortgage, the Indenture, the Intercreditor Agreement and the other Note Documents, or the enforcement, compromise or settlement of the Indebtedness or any claim under this Mortgage, the Indenture, the Intercreditor Agreement and the other Note Documents, and for the curing thereof, or for defending or asserting the rights and claims of Mortgagee in respect thereof, by litigation or otherwise.

Section 5.10 No Mortgagee in Possession. Neither the enforcement of any of the remedies under this Article 5, the assignment of the Rents and Leases under Article 6, the security interests under Article 7, nor any other remedies afforded to Mortgagee under the Indenture, the Intercreditor Agreement or the other Note Documents, at law or in equity shall cause Mortgagee to be deemed or construed to be a mortgagee in possession of the Mortgaged Property, to obligate Mortgagee to lease the Mortgaged Property or attempt to do so, or to take any action, incur any expense, or perform or discharge any obligation, duty or liability whatsoever under any of the Leases or otherwise.

Section 5.11 WAIVER OF MORTGAGOR'S RIGHTS. BY EXECUTION OF THIS MORTGAGE, MORTGAGOR EXPRESSLY: (A) ACKNOWLEDGES THE RIGHT OF MORTGAGEE TO ACCELERATE THE INDEBTEDNESS, IN THE MANNER SET FORTH IN THE INDENTURE, EVIDENCED BY THE INDENTURE, THE INTERCREDITOR AGREEMENT OR OTHER NOTE DOCUMENTS UPON THE OCCURRENCE OF AN EVENT OF DEFAULT; (B) TO THE EXTENT ALLOWED BY APPLICABLE LAW, AND EXCEPT AS SET FORTH IN THE INDENTURE OR ANY OF THE NOTE DOCUMENTS, WAIVES ANY AND ALL RIGHTS WHICH MORTGAGOR MAY HAVE UNDER THE CONSTITUTION OF THE UNITED STATES, THE VARIOUS PROVISIONS OF THE CONSTITUTIONS FOR THE SEVERAL STATES, OR BY REASON OF ANY OTHER APPLICABLE LAW, TO NOTICE AND TO JUDICIAL HEARING PRIOR TO THE EXERCISE BY MORTGAGEE OF ANY RIGHT OR REMEDY HEREIN PROVIDED TO MORTGAGEE; (C) ACKNOWLEDGES THAT MORTGAGOR HAS READ THIS MORTGAGE AND ITS PROVISIONS HAVE BEEN EXPLAINED FULLY TO MORTGAGOR AND MORTGAGOR HAS CONSULTED WITH LEGAL COUNSEL OF MORTGAGOR'S CHOICE PRIOR TO EXECUTING THIS MORTGAGE; AND (D) ACKNOWLEDGES THAT ALL WAIVERS OF THE AFORESAID RIGHTS OF MORTGAGOR HAVE BEEN MADE KNOWINGLY, INTENTIONALLY AND WILLINGLY BY MORTGAGOR AS PART OF A BARGAINED FOR TRANSACTION.

ARTICLE 6

Section 6.1 Assignment. In furtherance of and in addition to the assignment made by Mortgagor in Section 2.1 of this Mortgage, Mortgagor hereby absolutely and unconditionally assigns, sells, transfers and conveys to Mortgagee all of its right, title and interest in and to all Leases, whether now existing or hereafter entered into, and all of its rights, title and interest in and to all Rents. This assignment is an absolute assignment and not an assignment for additional security only. So long as no Event of Default shall have occurred and be continuing and to the extent not prohibited by the Indenture or the Intercreditor Agreement, Mortgagor shall have a revocable license from Mortgagee to exercise all rights extended to the landlord under the Leases, including the right to receive and collect all Rents and to hold the Rents in trust for use in the payment and performance of the Obligations and to otherwise use the same. The foregoing license is granted subject to the conditional limitation that no Event of Default shall have occurred and be continuing. Upon the occurrence and during the continuance of an Event of Default, whether or not legal proceedings have commenced, and without regard to waste, adequacy of security for the Obligations or solvency of Mortgagor, the license herein granted shall automatically expire and terminate, without notice by Mortgagee (any such notice being hereby expressly waived by Mortgagor). Prior to a Discharge of the Priority Liens, Mortgagor's obligations under this Section 6.1 shall be satisfied so long as the Priority Lien Representative holds Mortgagor's right, title and interest in and to all Leases, whether now existing or hereafter entered into, and all of Mortgagor's rights, title and interest in and to all Rents as agent for Collateral Agent.

Section 6.2 Perfection Upon Recordation. Mortgagor acknowledges that Mortgagee has taken all actions necessary to obtain, and that upon recordation of this Mortgage and the filing of appropriate UCC financing statements, Mortgagee shall have, to the extent permitted under applicable law, a valid and fully perfected security interest, present assignment of the Rents arising out of the Leases and all security for such Leases (subject to the Permitted Liens and Priority Liens). Mortgagor acknowledges and agrees that upon recordation of this Mortgage, Mortgagee's interest in the Rents shall be deemed to be fully perfected, "choate" and enforced as to Mortgagor and all third parties, including, without limitation, any subsequently appointed Mortgagee in any case under Title 11 of the United States Code (the "Bankruptcy Code"), without the necessity of commencing a foreclosure action with respect to this Mortgage, making formal demand for the Rents, obtaining the appointment of a receiver or taking any other affirmative action.

Section 6.3 Bankruptcy Provisions. Without limitation of the absolute nature of the assignment of the Rents hereunder, Mortgagor and Mortgagee agree that (a) this Mortgage shall constitute a "security agreement" for purposes of Section 552(b) of the Bankruptcy Code, (b) the security interest created by this Mortgage extends to property of Mortgagor acquired before the commencement of a case in bankruptcy and to all amounts paid as Rents and (c) such security interest shall extend to all Rents acquired by the estate after the commencement of any case in bankruptcy.

Section 6.4 No Merger of Estates. So long as part of the Indebtedness and the Obligations secured hereby remain unpaid and undischarged, the fee and leasehold estates to the Mortgaged Property shall not merge, but shall remain separate and distinct, notwithstanding the union of such estates either in Mortgagor, Mortgagee, any tenant or any third party by purchase or otherwise.

SECURITY AGREEMENT

Section 7.1 Security Interest. This Mortgage constitutes a "security agreement" on personal property within the meaning of the UCC and other applicable law and with respect to the Fixtures, Leases, Rents, Deposit Accounts, Property Agreements, Tax Refunds, Proceeds, Insurance and Condemnation Awards. To this end, Mortgagor grants to Mortgagee a security interest, subject only to

the Permitted Liens and the Priority Liens, in the Fixtures, Leases, Rents, Deposit Accounts, Property Agreements, Tax Refunds, Proceeds, Insurance and Condemnation Awards and all other Mortgaged Property which is personal property to secure the payment of the Indebtedness and performance of the Obligations, and agrees that Mortgagee shall have all the rights and remedies of a secured party under the UCC with respect to such property. Any notice of sale, disposition or other intended action by Mortgagee with respect to the Fixtures, Leases, Rents, Deposit Accounts, Property Agreements, Tax Refunds, Proceeds, Insurance and Condemnation Awards sent to Mortgagor at least ten (10) days prior to any action under the UCC shall constitute reasonable notice to Mortgagor. THE TERM "MORTGAGED PROPERTY" IS INTENDED TO EXCLUDE ALL ITEMS OF PERSONAL PROPERTY IN WHICH MORTGAGEE HAS OBTAINED AND/OR PERFECTED A SECURITY INTEREST UNDER SEPARATE INSTRUMENTS.

Section 7.2 Financing Statements. Mortgagor shall execute and deliver to Mortgagee, in form and substance satisfactory to Mortgagee, such financing statements and such further assurances as Mortgagee may, from time to time, reasonably consider necessary to create, perfect and preserve Mortgagee's security interest hereunder and Mortgagee may cause such statements and assurances to be recorded and filed, at such times and places as may be required or permitted by law to so create, perfect and preserve such security interest. Mortgagor's state of organization is the State of Washington

Section 7.3 Fixture Filing. This Mortgage shall also constitute a "fixture filing" for the purposes of the UCC against all of the Mortgaged Property which is or is to become fixtures. Information concerning the security interest herein granted may be obtained at the address of Debtor (Mortgagor) and Secured Party (Mortgagee) as set forth in the first paragraph of this Mortgage.
