LEASE AGREEMENT

This LEASE, made the 4^th day of May, 2007 by and between 300 W. FAYETTE STREET, LLC, a Delaware limited liability company (hereinafter called "Landlord"), and BIOANALYTICAL SYSTEMS, INC., an Indiana corporation (hereinafter called "Tenant").

WITNESSETH:

1. Demise and Term.

(a)That in consideration of the mutual promises herein contained, the Landlord hereby rents to the Tenant, and the latter does hereby rent from the former, the Premises described as floors Basement, 2, and 3 and the lobby vestibule of 300-306 W. Fayette Street, Baltimore City, Maryland, more particularly described on Exhibit A, attached hereto and made a part hereof, containing approximately 46,000 rentable square feet (the "Premises") for the term of seven (7) years beginning on the Commencement Date as hereinafter defined. The number of rentable square feet in the Premises and the Building shall be determined by Landlord's architect pursuant to the American National Standard Method of Measuring Floor Area in Office Buildings, ANSI/BOMA Z65.1 - 1996. The building at 300-306 W. Fayette Street will hereinafter be referred to as the "Building".

(b)The Commencement Date, whenever used herein, shall be January 5, 2008. On the Commencement Date, Tenant's obligations under this Lease will begin. This Lease is effective as of the date hereof. The Term will commence on the Commencement Date and will expire, unless extended pursuant to the terms and conditions of this Lease, at midnight on January 4, 2015 (the "Expiration Date").

(c)Renewal Option. Provided that, at the time of each such exercise, (i) the originally named Tenant shall be in occupancy of the Premises, and (ii) Tenant is not then in default beyond expiration of all applicable notice, grace and cure periods, Tenant may have two (2) five (5) year options to renew this lease at the Market Rent. Tenant shall exercise each option by providing written notice to Landlord of its election to exercise such option no later than twelve (12) months prior to the expiration of the Term or the first Renewal Term, as applicable ("Renewal Notice"); provided, however, that if Tenant's estate hereunder shall terminate after exercise of such option to renew but prior to the commencement of the Renewal Term, Tenant's option to renew shall expire upon such termination.

(i)No assignee or subtenant under this Lease shall have the right to exercise any renewal option.

(ii)All terms, covenants, and conditions of this Lease shall remain in full force and effect during each Renewal Term, except that the Base Rent applicable to the Renewal Term shall be as set forth in this Section 1(c). If the Tenant fails to give notice exercising the foregoing option by the date required herein, then Tenant's rights and options to renew shall be automatically terminated and of no further force or effect. All references in this Lease to the "Term" shall include each Renewal Term for which Tenant shall have effectively exercised its renewal option.

(iii)The "Market Rent" shall be the fair market rent for the Premises determined as of the date occurring twelve (12) months prior to the end of the Original Term or the first Renewal Term, to be effective at the commencement of each new term, taking into account all then relevant factors (including, without limitation, the presence or absence of concessions, allowances, abatements and the like). If Tenant exercises its option to renew hereunder, Tenant and Landlord shall make a good faith effort to agree on the Market Rent. Landlord shall provide Tenant the Market Rate within thirty (30) days of Tenant's exercise of its option to renew. The "Outside Negotiation Date" is defined as the date that is sixty (60) days after Tenant's exercise of its option to renew. If Landlord and Tenant are unable to agree upon the Market Rent by the Outside Negotiation Date, then, Landlord and Tenant shall determine the Market Rent in accordance with the arbitration procedure set forth in this section 1(c).

(iv)Within ten (10) days after the Outside Negotiation Date, the parties shall each appoint a commercial real estate broker (hereinafter referred to as the "Appraiser") who shall act on behalf of and bind the Landlord and Tenant, respectively. Each Appraiser shall have at least ten (10) years' experience as a broker of commercial leasehold estates, and shall be knowledgeable in office rentals in the Central Business District of Baltimore, Maryland market.

(v)Each Appraiser so appointed shall be instructed to determine independently of the other the Market Rent pursuant to this Section 1(c) within ten (10) business days after the making of Landlord's or Tenant's request. If within ten (10) business days after the making of Landlord's or Tenant's request, Landlord's Appraiser and Tenant's Appraiser shall mutually agree upon the determination of the Market Rent, their determination shall be final and binding upon the parties.

(vi)If Landlord's Appraiser and Tenant's Appraiser shall fail to agree within said 10-day period, and if the difference between the amounts so determined shall not exceed four percent (4%) of the lesser of such amounts, then the Market Rent shall be an amount equal to fifty percent (50%) of the sum of the amounts so determined (i.e., the average of the two determinations).

(vii)If the difference between the amounts so determined exceeds four percent (4%) of the lesser of such amounts, then (A) such two Appraisers shall have twenty (20) days to appoint a third Appraiser; (B) if such Appraisers fail to do so, then either Landlord or Tenant may request the American Arbitration Association in Maryland or any successor organization thereto to appoint an Appraiser within twenty (20) days of such request and both parties shall be bound by any appointment so made within such twenty (20) day period; and (C) if no such third Appraiser shall have been appointed within such twenty (20) days or within ninety (90) days of the original request for a determination of the Market Rent, whichever is earlier, either Landlord or Tenant may apply to the Administrative Judge of the Circuit Court of Baltimore City to make such appointment.

2

(viii)Such third Appraiser, however selected, shall be jointly instructed by Landlord and Tenant to determine the Market Rent in accordance with this Section 1(c) in an amount equal to either the determination of Landlord's Appraiser or the determination of Tenant's Appraiser, within twenty (20) days after such Appraiser's appointment. The third Appraiser may not choose a third number; the third Appraiser must choose the Tenant's number or the Landlord's number. The determination of such third Appraiser shall be final and binding upon Landlord and Tenant as to the Market Rent.

(ix)Landlord shall pay the fees of Landlord's Appraiser and Tenant shall pay the fees of Tenant's Appraiser. The fees of the third Appraiser, if any, shall be paid by Landlord if the third Appraiser's determination of the Market Rent equals that of Tenant's Appraiser, or by Tenant if the third Appraiser's determination of the Market Rent equals that of Landlord's Appraiser.

(x)The final determination of such Appraiser or Appraisers shall be in writing and shall be binding and conclusive on the parties, each of whom shall receive counterpart copies thereof. In rendering such decision the Appraisers shall not add to, subtract from, or otherwise modify the provisions of this Lease. In determining the Market Rent, the Appraisers shall consider all the items set forth above for consideration in determining the Market Rent. Instructions to such effect, including a copy of this Section 1(c) of this Lease, shall be given to the Appraisers.

(d)Tenant's Right to Lease Storage Space. If Tenant notifies Landlord that it wishes to lease an area of the sub-basement level of the Building for storage, Landlord shall add such designated area to Tenant's Premises. Tenant may wall off and secure such area. The Base Rent for such storage space shall be twenty-five percent (25%) of the then current Base Rent for the Premises (in other words, the Base Rent for the storage area will increase by twelve and one-half cents ($0.125) per year during the initial term). The square footage of such space shall not be included in the calculation of Tenant's Proportionate Share. Also, Tenant will be provided with an allowance of Four Dollars and Thirty-seven Cents ($4.37) per rentable square foot of storage space for Tenant Improvements.

2.Base Rent.The total monthly Base Rent for each month of the Term after the Commencement Date shall be paid by Tenant in advance, on the first day of each month, in equal monthly installments of Forty-Four Thousand Eighty-Three Dollars ($44,083.00) (the Base Rent to be adjusted if the size of the Premises changes following an actual measurement of the Premises, as set forth above). The Base Rent shall be the product of the total rentable square feet in the Premises multiplied by the rental rate per square foot. On the Commencement Date, the rental rate shall be Eleven Dollars and Fifty Cents ($11.50), and the rental rate shall increase by Fifty Cents ($0.50) each year beginning January 1st, 2009 during the Term, as follows:

January 1, 2009:	$12.00
January 1, 2010:	$12.50
January 1, 2011:	$13.00
January 1, 2012:	$13.50
January 1, 2013:	$14.00
January 1, 2014:	$14.50

3

If the Term does not begin on the first day or end on the last day of a month, the Base Rent for that partial month shall be prorated by multiplying the monthly Base Rent by a fraction, the numerator of which is the number of days of the partial month included in the Term and the denominator of which is the total number of days in that full calendar month. The first installment of Base Rent shall be the pro-rated amount due for January, 2008, which shall be due and payable on the Commencement Date (including Tenant's Proportionate Share of estimated Real Estate Taxes and Operating Costs).

3.Payment, Late Charge, Time of Essence.The Tenant covenants to pay the Base Rent as herein provided without any deduction whatsoever, and without any obligation on the Landlord to make demand for it, failing which the Tenant shall pay to the Landlord as Additional Rent, after the fifth (5th) Business Day ("Business Day" means every day except Saturdays, Sundays and Federal Holidays) that such payment remains due but unpaid, a late charge equal to five percent (5%) of such payment which remains due but unpaid. Time is of the essence in this Lease. Payments shall be made to Landlord at the address set forth herein for Notice.

4.Tenant's Proportionate Share. Tenant's Proportionate Share means a fraction, the numerator of which is the number of rentable square feet of the Premises and the denominator of which is the number of rentable square feet in the Building, subject to adjustment from time to time as the numerator and denominator change. Given the approximate size of the Premises (see Section 1(a)) and the number of rentable square feet in the Building, Tenant's Proportionate Share on the date hereof is 46,000/112,970 or forty and seven-tenths percent (40.7%), which is subject to further modification as final measurements are made.

5.Real Estate Taxes. Tenant, as of the Commencement Date, covenants and agrees to pay Landlord within thirty (30) days of Landlord's notice to Tenant, as Additional Rent, Tenant's Proportionate Share of any real estate taxes assessed against the land and Building in which the Premises is included. If this Lease shall be in effect for less than a full tax fiscal year, Tenant shall pay a prorated share of the taxes, based upon the number of days that this Lease is in effect. "Taxes" as used herein shall include, but not by way of limitation, all real property taxes, and any and all other benefits or assessments which may be levied on the Premises or the land and Building in which the same are situate, but shall not include any penalties or late fees, income tax on the income or Base Rent payable hereunder or any inheritance, estate, succession, transfer, gift, franchise, corporation, income or profit tax that is or may be imposed upon Landlord. Any reasonable expense incurred by Landlord in contesting any real estate tax shall be included as an item of taxes for the purpose of computing Additional Rent due the Landlord.

(a)Landlord shall collect, together with the monthly payment of Base Rent hereunder, an amount equal to one-twelfth (1/12) of Tenant's Proportionate Share of the estimated real estate taxes due for the next succeeding fiscal year so that Landlord shall have an amount sufficient to pay such taxes when due. Landlord may also make adjustments when necessary in the case of special assessments or taxes so that Landlord will have an amount sufficient to pay such taxes when due. Appropriate adjustments shall be made between Landlord and Tenant upon the determination of the actual amount of such taxes.

4

Appropriate adjustments shall be made between Landlord and Tenant upon the determination of the actual amount of such Operating Costs.

(c)"Operating Costs" means any and all reasonable costs and expenses incurred by the Landlord for services performed by the Landlord or by others on behalf of the Landlord with respect to the operation and maintenance of the Premises, Building and the Common Facilities located therein, in a manner deemed reasonable and appropriate by Landlord, including, without limitation, all costs and expenses of Landlord providing the following services:

7. Care of Premises.

(a)The Tenant agrees that it will take good care (including its own interior janitorial service) of the Premises, fixtures, and appurtenances, including the following items and elements serving the Premises: plumbing, heating and air conditioning equipment (excluding that on the exterior of the building), and keep same in good order and repair throughout the Term of this Lease in a manner comparable to the order and state of repair extant of the Commencement Date, and suffer or permit no waste or injury; Landlord shall assign to Tenant, for the benefit of the Tenant, to the extent they are assignable or otherwise available for the benefit of the Tenant, any warranties on such equipment furnished Landlord by the Tenant and/or provider thereof; that Tenant will conform to all laws, orders, and regulations of the Federal, State, County and City authorities or any of their departments, and will not, through its own act or neglect, cause any situation to exist in or about the Premises which would constitute a violation of any applicable Federal, State, County, or City Code Regulation or Ordinance governing use, occupancy, health, sanitation, or fire; that it will save harmless the Landlord from any liability arising from injury to person or property caused by any act or omission of Tenant, his agents, employees or guests; that it will repair at or before the end of the term, or sooner if so requested by the Landlord, all injury done by the installation or removal of furniture or other property, and will surrender the Premises at the end of the Term broom cleaned in as good condition as they were at the beginning of the term, ordinary wear and tear, condemnation, alterations as permitted by this Lease and casualties by fire and elements excepted. In the event of any increase in the cost of insurance as a result of the failure of the Tenant to comply with the provisions of this Paragraph, the Tenant will pay the amount of such increase as Additional Rent within thirty (30) days after the Landlord's written demand, which will provide evidence that the stated actions increased the cost of insurance.

The Landlord shall be under no liability to the Tenant for any discontinuance of heat, air conditioning, and hot water unless due solely to Landlord's negligence. The Landlord shall not be liable for any loss or damage to the Tenant caused by rain, snow, water or storms that may leak into or flow from any part of the premises through any defects in the roof or plumbing or from any other source unless due solely to Landlord's negligence.

9

(c)Landlord agrees to maintain and will keep in good repair the Common Facilities, the exterior walls of the Building, the roof, slabs, foundations and structural elements of the Building.

If the Premises, or any portion thereof critical to performance of Tenant's business, are rendered unfit for the business purposes for which it was leased due to a structural problem in the exterior walls, structural columns, roof, roof penetrations or structural floor, for more than thirty (30) consecutive days, then the Base Rent shall abate proportionately to the amount of space rendered unfit for the business purposes for which it was leased for the amount of time such condition shall exist.

(d)Tenant shall not place a load upon any floor of the Premises that exceeds the lesser of (i) floor load per square foot, which such floor was designed to carry or (ii) the maximum floor load per square foot allowed by law. Business machines and mechanical equipment shall be placed and maintained by Tenant, at Tenant's expense, in settings sufficient in Landlord's reasonable judgment to absorb and prevent vibration, noise and annoyance.

(e)There shall be no allowance to Tenant for any diminution of rental value and no liability on the part of the Landlord by reason of inconvenience, annoyance or injury to business arising from the making by Landlord, Tenant or others of any repairs in or to the Building or the Premises, or in or to the fixtures, appurtenances or equipment thereof. Except in case of emergency, as determined in Landlord's sole discretion, Landlord will use commercially reasonable efforts to minimize any interference with Tenant's use and occupancy in connection with Landlord's entering to make repairs.

(f)In the event Tenant shall not proceed promptly and diligently to make any repairs or perform any obligation imposed upon it by this Section 6 within ten (10) days after receiving written notice from Landlord to make such repairs or perform such obligation (unless such repairs or obligation is of such nature that it cannot be cured within such ten (10) day period, in which case Tenant shall have such longer period of time as is required, provided that Tenant shall diligently prosecute such repairs or perform such obligation), then and in such event, Landlord, may, at its option, enter the Premises and do and perform the things specified in said notice, without liability on the part of Landlord for any loss or damage resulting from any such action by Landlord and Tenant agrees to pay promptly upon demand any cost or expense incurred by Landlord in taking such action, including an administrative fee equal to ten percent (10%) of the cost or expense incurred.

(g)Landlord shall provide, at its expense, subject to reimbursement pursuant to Section 6 of this Lease, all necessary services and maintenance to operate a professional office building, including, but not limited to, all necessary snow removal from the parking lots and sidewalks.

The Landlord will use reasonable efforts not to disturb Tenant's use or enjoyment of Premises if Landlord or his agents enters non-secured areas. The Landlord will not, except in the case of emergency, enter secured areas during active clinical studies without advance notice to Tenant. To ensure federal regulatory compliance during active studies, Tenant's chaperone will be required for Landlord or his agents.

13.Alterations.

The Common Facilities shall at all times be subject to the exclusive control and management of Landlord.

If a default by Tenant occurs under this Lease, without prejudice to Landlord's other remedies, Landlord may, but will not be obligated to, apply all or any portion of the Security Deposit to compensate Landlord (whether in whole or in part) for such default. If any portion of the Security Deposit is so applied, Tenant shall be obligated to deposit with Landlord, within fifteen (15) days thereafter, the amount necessary to restore the balance of the Security Deposit to its original amount; provided, however, that neither the application of the Security Deposit as set forth above nor the payment by Tenant to restore the Security Deposit will operate to cure the default or to estop Landlord from pursuing any remedy to which Landlord would otherwise be entitled.

(c)Transfer of Security Deposit. If any sale or transfer occurs of Landlord's interest in the Building, Landlord may transfer the Security Deposit to such purchaser or transferee, in which event Tenant will look solely to the new landlord for the return of the Security Deposit and Landlord will thereupon be released from all liability to Tenant for the return of the Security Deposit. The Security Deposit will not be transferable by Tenant to any assignee or subtenant, but will be held and returned directly to Tenant.

18.Damage to Premises. If the Premises are partially damaged by fire or other casualty Landlord shall make repairs as speedily as conveniently possible. If the damage is so extreme as to render the Premises untenantable for the Permitted Use, the Base Rent shall cease until the Premises are put into repair by the Landlord. In the event of a total or substantial destruction of the Building of which the Premises form a part, or if in the judgment of the Landlord the damage to the Premises cannot be repaired within one hundred twenty (120) days, and if the Landlord shall decide not to restore or repair the same, or shall decide to demolish the building, then the Landlord or Tenant may, within forty-five (45) days after such fire or other casualty, by notification to the other party, terminate this Lease.

In no event shall Landlord be liable for any loss or damage sustained by Tenant by reason of fire or other accidental casualty.

14

In the event more than fifty (50%) percent of the building is destroyed and the Premises are untenantable for the Permitted Use, the Tenant may terminate this Lease upon thirty (30) days prior written notice to the Landlord.

19.Waiver or Breach. No waiver of any breach of the covenants, provisions or conditions contained in this Lease shall be construed as a waiver of the covenant itself or any subsequent breach itself; and if any breach shall occur and afterwards be compromised, settled or adjusted, this Lease shall continue in full force and effect as if no breach had occurred.

20.Rules and Regulations. Tenant shall comply with all rules and regulations of 300-306 West Fayette Street, which rules and regulations are attached hereto as Exhibit C and are hereby made a part of this Agreement.

39.Right of First Offer.

(a)Before Landlord leases any Available Space (as defined below) to any unrelated third party, Landlord will first offer such Available Space to Tenant for lease, by written notice to Tenant ("Landlord's Offer Notice"). As used in this Section 39, "Available Space" shall mean and refer to any office space which "becomes available" for leasing by the Landlord on the fourth (4^th) floor of the Building following the initial leasing of the Building, from time to time during the Term. Space shall be deemed to "become available" when the lease for any current tenant expires or is due to expire and renewal of such lease is not then available or is otherwise terminated; such space shall not be deemed to "become available" if the space is assigned or subleased by the current tenant or is re-let by the current tenant by renewal extension, option or renegotiation. Landlord's Offer Notice shall specify the rent for Available Space (which shall equal the Market Rent for the Available Space, if the space is offered for a term beginning after January 1, 2010; or on the same rental terms as are being paid for the Premises pursuant to this Lease, with a Tenant Improvement Allowance of Fifteen Dollars ($15.00) per rentable square foot if the space is offered for a term beginning before December 31, 2009), the term of the lease for such Available Space shall be co-terminus with the Term, and all other material terms and conditions, including the rent commencement date with respect to the Available Space, which date shall be sixty (60) days from the date the Available Space is available for Tenant to occupy (all of the foregoing collectively, the "Offered Terms") which will apply to the Available Space.

If Tenant timely so elects to lease the Available Space on the Offered Terms, but disputes Landlord's determination of Market Rent for the Available Space, and the parties do not agree on the Market Rent within twenty (20) days after delivery of such notice from Tenant, then Tenant may initiate the procedure set forth in Section 1(c) hereof to determine the Market Rent by giving notice to Landlord within an additional ten (10) days after the end of such twenty (20) day period. If Tenant fails to timely submit the dispute for arbitration within such period, then Landlord's determination of Market Rent shall be binding on the parties. Landlord and Tenant shall, within fifteen (15) Business Days after receipt of reasonable draft documentation from Landlord, execute an amendment to this Lease incorporating the Available Space into the Premises upon the Offered Terms contained in Landlord's Offer Notice or the determined Market Rent (as the case may be), and otherwise on substantially the same terms and conditions as contained in this Lease.

(b)Notwithstanding any contrary provision of this Section 39 or any other provision of this Lease, any exercise by Tenant of its right to lease Available Space shall be void and of no effect unless on the date Tenant notifies Landlord that it elects to lease Available Space and on the commencement date of the amendment for the Available Space (i) this Lease is in full force and effect, and (ii) no Event of Default has occurred under this Lease which remains continuing and uncured after applicable notice and cure periods, and (iii) the originally named Tenant is occupying the entire Premises for the conduct of its business.

SUBORDINATION, NON-DISTURBANCE

AND ATTORNMENT AGREEMENT

This Subordination, Non-Disturbance and Attornment Agreement ("Agreement"), is made as of this _____ day of ____________, 200__ among GMAC COMMERCIAL MORTGAGE CORPORATION, a California corporation ("Lender"), ______________, a ____________________ ("Landlord"), and ____________________, a ___________________ ("Tenant").

BACKGROUND

A.Lender has agreed to make a loan to Landlord in the original principal amount $___________ ("Loan"), which will be secured by a mortgage, deed of trust or similar security instrument (either, "Security Instrument") on Landlord's property described more particularly on Exhibit A attached hereto ("Property").

B.Tenant is the present lessee under that certain lease agreement between Landlord and Tenant dated __________________, as thereafter modified and supplemented ("Lease"), demising a portion of the Property described more particularly in the Lease ("Leased Space").

C.A requirement of the Loan is that Tenant's Lease be subordinated to the Security Instrument. Landlord has requested Tenant to so subordinate the Lease in exchange for Lender's agreement not to disturb Tenant's possession of the Leased Space upon the conditions set forth in this Agreement.

NOW, THEREFORE, in consideration of the mutual promises of this Agreement, and intending to be legally bound hereby, the parties hereto agree as follows:

1.Subordination. Tenant agrees that the Lease, and all estates, options and rights created under the Lease, hereby are subordinated and made subject to the lien and effect of the Security Instrument, as if the Security Instrument had been executed and recorded prior to the Lease.

B-2

Last Revised 12-31-02

Loan Number: ____________

2.Nondisturbance. Lender agrees that no foreclosure (whether judicial or nonjudicial), deed-in-lieu of foreclosure, or other sale of the Property in connection with enforcement of the Security Instrument or otherwise in satisfaction of the Loan shall operate to terminate the Lease or Tenant's rights thereunder to possess and use the Leased Space provided, however, that (a) the term of the Lease has commenced, (b) Tenant is in possession of the Leased Space, and (c) the Lease is in full force and effect and no uncured default exists under the Lease.

3.Attornment. Tenant agrees to attorn to and recognize as its landlord under the Lease each party acquiring legal title to the Property by foreclosure (whether judicial or nonjudicial) of the Security Instrument, deed-in-lieu of foreclosure, or other sale in connection with enforcement of the Security Instrument or otherwise in satisfaction of the Loan ("Successor Owner"). Provided that the conditions set forth in Section 2 above are met at the time Successor Owner becomes owner of the Property, Successor Owner shall perform all obligations of the landlord under the Lease arising from and after the date title to the Property is transferred to Successor Owner. In no event, however, will any Successor Owner be: (a) liable for any default, act or omission of any prior landlord under the Lease; (b) subject to any offset or defense which Tenant may have against any prior landlord under the Lease; (c) bound by any payment of rent or additional rent made by Tenant to Landlord more than 30 days in advance; (d) bound by any modification or supplement to the Lease, or waiver of Lease terms, made without Lender's written consent thereto; (e) liable for the return of any security deposit or other prepaid charge paid by Tenant under the Lease, except to the extent such amounts were actually received by Lender, (f) liable or bound by any right of first refusal or option to purchase all or any portion of the Property; or (g) liable for construction or completion of any improvements to the Property or as required under the Lease for Tenant's use and occupancy (whenever arising). Although the foregoing provisions of this Agreement are self-operative, Tenant agrees to execute and deliver to Lender or any Successor Owner such further instruments as Lender or a Successor Owner may from time to time request in order to confirm Agreement. If any liability of Successor Owner does arise pursuant to this Agreement, such liability shall be limited to Successor Owner's interest in the Property.

4.Rent Payments; Notice to Tenant Regarding Rent Payments. Tenant agrees not to pay rent more than one (1) month in advance unless otherwise specified in the Lease. After notice is given to Tenant by Lender that Landlord is in default under the Security Instrument and that the rentals under the Lease are to be paid to Lender directly pursuant to the assignment of leases and rents granted by Landlord to Lender in connection therewith, Tenant shall thereafter pay to Lender all rent and all other amounts due or to become due to Landlord under the Lease. Landlord hereby expressly authorizes Tenant to make such payments to Lender upon reliance on Lender's written notice (without any inquiry into the factual basis for such notice or any prior notice to or consent from Landlord) and hereby releases Tenant from all liability to Landlord in connection with Tenant's compliance with Lender's written instructions.

5.Lender Opportunity to Cure Landlord Defaults. Tenant agrees that, until the Security Instrument is released by Lender, it will not exercise any remedies under the Lease following a Landlord default without having first given to Lender (a) written notice of the alleged Landlord default and (b) the opportunity to cure such default within the longer of (i) 30 days after the cure period provided under the Lease to Landlord, (ii) 30 days from Landlord's receipt of Tenant's notice to Lender of a Landlord default, or (iii) if the cure of such default requires possession of the Property, 30 days after Lender has obtained possession of the Property; provided that, in each case, if such default cannot reasonably be cured within such 30-day period and Lender has diligently commenced to cure such default promptly within the time contemplated by this Agreement, such 30-day period shall be extended for so long as it shall require Lender, in the exercise of due diligence, to cure such default, but, unless the parties otherwise agree, in no event shall the entire cure period be more than 120 days. Tenant acknowledges that Lender is not obligated to cure any Landlord default, but if Lender elects to do so, Tenant agrees to accept care by Lender as that of Landlord under the Lease and will not exercise any right or remedy under the Lease for a Landlord default. Performance rendered by Lender on Landlord's behalf is without prejudice to Lender's rights against Landlord under the Security Instrument or any other documents executed by Landlord in favor of Lender in connection with the Loan.
