This subordination shall be self-operative and no further instrument of subordination shall be required.

If any proceedings are commenced to foreclose any mortgage or deed of trust encumbering the Premises, Tenant agrees to attorn to the purchaser at the foreclosure sale, if requested to do so by any such purchaser, and to recognize such purchaser as the Landlord under this Lease, provided such purchaser shall recognize Tenant’s tenancy under this Lease and agree that Tenant’s rights hereunder shall not be disturbed so long as Tenant has not committed any event of default as to which the applicable cure period has expired.

25. CONDEMNATION

(a) If the whole of the Premises shall be taken by any public or quasi-public authority under the power of eminent domain, condemnation or conveyance in lieu thereof, then this Lease shall terminate as of the date on which possession of the Premises is required to be surrendered to the condemning authority and Landlord shall be entitled to the entire amount of any award, including all income, rent, award or any interest whatsoever in or about such sum which may be paid in connection

Macro Genics, Inc. 0000 Xxxxxxx Xxxxxx Xxxxx Xxxxxxxxx, Xxxxxxxx Lease Agreement Page 13 of 23

with such governmental action. Tenant shall have no claim against Landlord or the condemning authority for the value of the unexpired term of this Lease. Tenant shall have the right to claim, however, the unamortized cost of any improvements or additions made to the Premises by Tenant at its cost, loss of good will, the value of any Tenant fixtures paid for by Tenant and furnishings and any moving expenses (collectively, “Tenant’s Claim”).

(b) If a portion of the Premises shall be so taken or conveyed, and if such partial taking or conveyance shall render the Premises unsuitable for the business of the Tenant, then the term of this Lease shall cease and terminate as of the date on which possession of the portion of the Premises is surrendered to the condemning authority, and Tenant shall have no claim against Landlord or the condemning authority for the value of any unexpired term of this Lease but will have the right to make Tenant’s Claim against public or quasi-public authority.

In the event that in Tenant’s reasonable judgment such partial taking or conveyance is not extensive enough to render the Premises untenantable for the business of Tenant, this Lease shall continue in full force and effect, except that the Minimum Rent shall be reduced in the same proportion that the floor area of the Premises so taken or conveyed bears to such floor area immediately prior to such taking or conveyance.

In the event of such partial taking and continuation of Lease, Landlord shall promptly restore the Premises as an architectural unit and as nearly as practical to the condition comparable to that which existed prior to the condemnation.

26. EVENTS OF DEFAULT

The occurrence of any of the following shall constitute an event of default hereunder:

(a) Failure of Tenant to pay installment of Minimum Rent or scheduled payments of Operating Expenses within five (5) days of the due date, or failure of Tenant to pay within five (5) days following written notice any other sum herein required to be paid by Tenant. Notwithstanding the foregoing, Landlord shall be required to deliver to Tenant written notice of the failure to pay Minimum Rent and/or such payments of Operating Expenses two (2) times in every twelve (12)-month period, in which event Tenant shall be deemed to be in default only if such failure continues for five (5) business days after receipt of such written notice from Landlord.

(b) Tenant’s failure to perform any other covenant or condition of this Lease within thirty (30) days following Tenant’s receipt of written notice from Landlord, unless the failure is of such a character as to require more than thirty (30) days to cure in which event Tenant’s failure to proceed diligently to cure such failure shall constitute an event of default.

27. LANDLORD’S REMEDIES

Upon the occurrence of any event of default, Landlord may, at Landlord’s sole option, exercise any or all of the following remedies, together with any such other remedies as may be available to Landlord at law or in equity.

(a) Landlord may terminate this Lease by giving Tenant written notice of its election to do so, as of a specified date not less than thirty (30) days after the date of the giving of such notice and this Lease shall then expire on the date so specified, and Landlord shall then be entitled to immediately regain possession of the Premises as if the date had been originally fixed as the expiration date of the term of this Lease. Landlord may then re-enter upon the Premises, with due process of law, and remove all persons therefrom, the statutory notice to quit or any other notice to quit being hereby expressly waived by Tenant. Tenant expressly agrees that the exercise by Landlord of the right of re-entry shall not be a bar to or prejudice in any way other legal remedies available to Landlord. In that event, Landlord shall be entitled to recover from Tenant periodically as and for damages an amount equal to the rent and additional rent reserved in this Lease less any and all amounts received by Landlord from the rental of the Premises to another tenant. Landlord may, in his own name, but as agent for Tenant, re-let the Premises. Any recovery by the Landlord shall be limited to the rent hereunder (plus any costs incurred in re-letting) less any rent actually paid by the new tenant.

(b) No termination of this Lease or any taking of possession of the Premises shall deprive Landlord of any of its remedies or actions against Tenant for past or future rent, nor shall the bringing of any action for rent or breach of covenant, or the resort to any other remedy herein provided for the recovery of rent, be construed as a waiver of the right to obtain possession of the Premises.

(c) In addition to any damages becoming due under this paragraph, Landlord shall be entitled to recover from Tenant and Tenant shall pay to Landlord an amount equal to all expenses, including reasonable attorneys’ fees, if any, incurred by the Landlord in recovering possession of the Premises, and all reasonable costs and charges for the care of said Premises while vacant, which damages shall be due and payable by Tenant to Landlord at such time or times as such expenses are incurred by the Landlord.

(d) In the event of an event of default by Tenant of any of the terms or conditions of this Lease, Landlord shall have the right of injunction and the right to invoke any remedy allowed by law or in equity as if no specific remedies of Landlord were set forth in this Lease.

(e) If default be made and a compromise and settlement shall be had thereupon, it shall not constitute a future waiver of any covenant herein contained, nor of the Lease itself.
