EXHIBIT 10.1
ASSIGNMENT AND ASSUMPTION OF LEASE
(9704 Medical Center Drive, Rockville, Maryland)
THIS ASSIGNMENT AND ASSUMPTION OF LEASE ("Assignment"), is made and dated for
reference purposes as of the 31st day of July, 2015 (the "Execution Date"), by
and between J. CRAIG VENTER INSTITUTE, INC., successor in interest to The
Institute for Genomic Research Inc., a Maryland non-stock corporation
("Assignor"), and MACROGENICS, INC., a Delaware corporation ("Assignee"), both
of whom may be referred to herein as the "Parties" and each of whom may be
referred to herein as a "Party."
RECITALS
A.            Assignor and BMR-Medical Center Drive LLC, a Delaware limited
liability company ("Landlord") are parties to that certain Lease dated May 3,
2010 (as amended by that certain First Amendment to Lease dated as of March 26,
2014, the "Lease").  Unless otherwise expressly defined herein, capitalized
terms used herein without definition shall have the same meaning given to such
terms in the Lease.
B.            This Assignment is being entered into for the purpose of
memorializing the assignment by Assignor to Assignee of the Lease, subject to
the terms and conditions of this Assignment and the Landlord Consent attached
hereto.
NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, the Parties hereto agree as follows:
1.            Defined Terms.  Unless otherwise expressly defined herein,
capitalized terms used herein without definition shall have the same meaning
given to such terms in the Lease.
2.            Surrender; Early Access Rights.  Assignor shall surrender the
Premises to Assignee in broom clean condition and in the condition required
under the Lease upon surrender of the Premises no later than December 1, 2015
(the "Surrender Date").  In addition, Assignor agrees to deliver the Premises to
Assignee in compliance with all Applicable Laws, including the ADA, and with all
Building systems, including elevator, plumbing, air conditioning, heating,
electrical, security, life, safety and power, and systems serving the lab of the
Premises, and the Generator in good working order, provided in no event shall
Assignor be obligated to remedy any non-compliance or satisfy any obligation
which is not the express obligation of the Tenant under the terms and conditions
of the Lease.  No later than thirty (30) days prior to the Surrender Date,
Assignee shall be required to conduct an inspection of the Premises and to
identify to Assignor any part of the Premises or the Generator that is not in
good working order; provided, however, that Assignee's completion of such
inspection and identification to Assignor or any part of the Premises or the
Generator that is not in good working order shall not release Assignor of any
obligations with respect to latent defects to the Premises or the Generator, or
any failure of the Premises or the Generator to be in good working order that
arises after Assignee's completion of such inspection and before the Surrender
Date.  If any part of the Premises or the Generator fails to comply with any of
the foregoing conditions as of the Surrender Date, and provided that the
satisfaction of such condition is not the express obligation of Landlord under
the terms and conditions of the Lease, then Assignee may (but shall not be
obligated to) perform such alterations as are required to bring the Premises or
the Generator, as applicable, into compliance with Applicable Laws and to cause
all Building systems and systems serving the lab of the Premises and the
Generator to be in good working order at Assignor's sole cost and expense. 
Notwithstanding the foregoing, to the extent that Assignor shall cause the
remediation of any recognized environmental conditions set forth in the Exit
Survey (as defined in the Landlord Consent) and compliance with any
recommendations set forth in the Exit Survey as of or prior to the Assignment
Date, and Assignor shall remain responsible for such obligations after
Assignor's surrender of the Premises and the occurrence of the Assignment Date.
Commencing on the Surrender Date and continuing until the Assignment Date (as
defined below) (the "Early Access Period"), Assignor shall grant Assignee and
its contractors, subcontracts and employees (collectively, the "Assignee Group")
a right of entry and access to the Premises for the purpose of installing
improvements and the placement of personal property, but not for the purpose of
conducting Tenant's business (the "Early Access Rights"), provided that Assignee
shall furnish to Assignor and Landlord evidence satisfactory to Assignor and
Landlord in advance that insurance coverages required of Assignor under the
provisions of Article 23 of the Lease are in effect, and such entry shall be
subject to all the terms and conditions of the Lease, other than the payment of
Base Rent or Tenant's Share of Operating Expenses.  In connection with the
foregoing, during the Early Access Period, Assignor shall retain access to the
Premises for the limited purpose of moving its Data Center located on the first
floor of the Premises to a new off-site location ("Data Center Move"); provided
that Assignor shall furnish to Assignee and Landlord evidence satisfactory to
Assignee and Landlord in advance that insurance coverages required of Assignor
under the provisions of Article 23 of the Lease are in effect, and such access
shall be subject to all the terms and conditions of the Lease; further provided
that Assignor shall promptly repair any damage to the Premises, the Building or
the Project caused by such retained access to the Premises or performance of the
Data Center Move or, if Assignee, in its sole discretion, shall elect to make
such repairs, to pay to Assignee promptly the costs and expenses incurred in
connection therewith.  On the Surrender Date, except for keys, security codes
and other electronic access cards to the Premises necessary for Assignor to
complete the Data Center Move (which shall be returned by Assignor to Assignee
on or before the end of the Early Access period), Assignor shall deliver all
keys, security codes and other electronic access cards to the Premises,
including all office and restroom keys, codes and access cards, and all FF&E
(defined below) to Assignee.  Assignee shall indemnify, save, defend (at
Landlord's or Assignor's option, as applicable, and with counsel reasonably
acceptable to Landlord or Assignor, as applicable) and hold Landlord, Assignor
and their respective affiliates, successors and assigns, and their respective
directors, officers, shareholders and employees, harmless from and against any
and all claims, damages, losses, suits, proceedings, costs and expenses,
including, without limitation, reasonable attorneys' fees (collectively,
"Claims") arising out of or relating to the exercise of the Early Access Rights
by the Assignee Group.  The later of (i) January 1, 2016 and (ii) the date upon
which Assignor shall have satisfied its obligations under this Section 2 and
Section 8 and any conditions precedent to Assignor's assignment of the Lease set
forth in the Landlord Consent attached hereto shall be the "Assignment Date."
Upon the Assignment Date, Assignor shall deliver to Assignee a duly executed
Bill of Sale and Assignment and Assumption Agreement in the form attached hereto
as Exhibit A, to effect the conveyance of the assets specified therein (the
"FF&E") and the assignment of the Assumed Contracts pursuant to Section 9
hereof.
3.            Assignment of Lease.  Subject to the provisions of this

assigns, transfers, conveys and delivers to Assignee, and Assignee hereby
accepts the assignment of, the Lease and all of the right, title, interest,
privileges and obligations of the "Tenant" thereunder.
4.            Assumption of Obligations.  Subject to the provisions of this
Assignment, by acceptance of this Assignment, effective as of the Assignment
Date, Assignee hereby assumes and agrees to perform and to be bound by all of
the terms, covenants, conditions and obligations imposed upon the "Tenant" under
the Lease accruing on or after the Assignment Date.
5.            Security Deposit.  Notwithstanding any provision to the contrary
set forth in this Assignment, Assignee acknowledges that Assignor is not
assigning to Assignee any right, title and interest in and to the Security
Deposit (or remaining balance thereof) delivered by Assignor to Landlord
pursuant to the Lease.  Assignor acknowledges that Assignor has consented to
Landlord's retention of the Security Deposit to be applied as a credit toward
the Leasing Cost Payment (as such term is defined in the Landlord Consent) to be
paid by Assignor to Landlord pursuant to Section 4 of the Landlord Consent. 
Accordingly, Assignor waives and relinquishes to Landlord all of Assignor's
right, title and interest in and to any refund of the Security Deposit.
6.            Assignor Indemnification.  As of the Assignment Date, Assignor
shall indemnify, save, defend (at Assignee's option and with counsel reasonably
acceptable to Assignee, except to the extent a Claim is defended by Assignor's
insurance company and such company expressly prohibits Assignor or Assignee from
approving such counsel) and hold Assignee and Assignee's affiliates, successors
and assigns, and their respective directors, officers, shareholders and
employees (collectively, the "Assignee Parties") harmless from and against any
and all Claims arising out of, by virtue of or in any way related to (i) the
breach by Assignor (or Assignor's failure to timely perform) any or all of the
obligations imposed on the "Tenant" under the Lease, which obligations accrued
as of or prior to the Assignment Date, including, without limitation, with
respect to the condition of the Premises; and (ii) Assignor's access of the
Premises during the Early Access Period for the Data Center Move and performance
of the Data Center Move.  As of the Assignment Date, Assignor hereby releases,
remises, acquits and forever discharges Assignee and the Assignee Parties from
and against any and all Claims arising out of or in any way relating to the
obligations imposed on the "Tenant" under the Lease, which obligations accrued
as of or prior to the Assignment Date (except to the extent any Claims are the
result of the acts, omissions, negligence or intentional misconduct of any of
the Assignee Group during the Early Access Period), or arising from the actions
of any of the Assignor Parties (as defined below) with respect to this Lease or
the Premises as of or prior to the Assignment Date, provided, however, that the
foregoing release shall not apply to any default or breach by Assignee of its
obligations under this Agreement.
7.            Assignee Indemnification.  As of the Assignment Date, Assignee
shall indemnify, save, defend (at Assignor's option and with counsel reasonably
acceptable to Assignor) and hold Assignor and Assignor's affiliates, successors
and assigns, and their respective directors, officers, shareholders and
employees (collectively, the "Assignor Parties") harmless from and against any
and all Claims arising out of, by virtue of or in any way related to the breach
by Assignee (or Assignee's failure to timely perform) any or all of the
obligations imposed on the Tenant under the Lease, which obligations accrue from
and after the Assignment Date.  As of the Assignment Date, Assignee hereby
releases, remises, acquits and forever discharges Assignor and the Assignor
Parties from and against any and all Claims arising out of or in any way
relating to the obligations imposed on the "Tenant" under the Lease, which
obligations accrued after the Assignment Date, or arising from the actions of
any of the Assignee Parties  with respect to this Lease or the Premises as of or
prior to the Assignment Date, provided, however, that the foregoing release
shall not apply to any default or breach by Assignor of its obligations under
this Agreement or with respect to any Claims arising from Assignor's access to
the Premises during the Early Access Period for the Data Center Move or
performance of the Data Center Move.
8.            Assignment Fee.  On or before the date that is four (4) business
days after the Execution Date, Assignor shall pay to Assignee an assignment fee
in the amount of Two Million Fifty Six Thousand Four Hundred Ninety Four Dollars
($2,056,494.00) in consideration of Assignee's assumption of the Lease pursuant
to this Assignment (the "Assignment Fee").
9.            Service Contracts.  Assignor shall reasonably cooperate with
Assignee to attempt to obtain consent (if required) to the transfer and
assignment to Assignee of any service contracts relating to the Premises that
Assignee has elected to assume in writing by written notice to Assignor no later
than twenty-one (21) days following the Execution Date (collectively, upon
transfer and assignment with any required consent (but explicitly excluding the
Lease), the "Assumed Contracts") and to terminate any service contracts relating
to the Premises that do not constitute Assumed Contracts effective as of the
Assignment Date.  Assignor shall reasonably cooperate with Assignee to transfer
and assign the Assumed Contracts to Assignee effective as of the Assignment
Date, including without limitation by delivering to Assignee a duly executed
Bill of Sale and Assignment and Assumption Agreement in the form attached hereto
as Exhibit A.
10.            Prorations.  Service fees under the Assumed Contracts either
prepaid by Assignor or payable for the calendar month during which the Surrender
Date occurs shall be prorated between Assignor and Assignee as of the Surrender
Date.  Following the Rent Commencement Date, the Parties agree to remit any
amounts owed to the other Party within ten (10) days of receipt of an invoice
and reasonable supporting documentation.

LANDLORD CONSENT
1.            Surrender Obligations.  At least ten (10) days prior to the
Surrender Date, and as a condition precedent to Assignor's assignment of the
Lease, Assignor shall deliver to Landlord and Assignee (a) an Exit Survey
prepared by an independent third party state-certified professional with
appropriate expertise or otherwise reasonably approved by Landlord and Assignee,
complying with the American National Standards Institute's Laboratory
Decommissioning guidelines (ANSI/AIHA Z9.11-2008) or any successor standards
published by ANSI or any successor organization (or, if ANSI and its successors
no longer exist, a similar entity publishing similar standards), which Exit
Survey must be reasonably acceptable to Landlord and Assignee, and (b) written
evidence of all appropriate governmental releases obtained by Assignor in
accordance with Applicable Laws, and Assignor shall (i) place Laboratory
Equipment Decontamination Forms on any decommissioned equipment that may remain
in the Premises to assure safe occupancy by future users and (ii) conduct a site

any recognized environmental conditions set forth in each Exit Survey and
compliance with any recommendations set forth in each Exit Survey as of or prior
to the Assignment Date, and Assignor shall remain responsible for such
obligations after Assignor's surrender of the Premises and the occurrence of the
Assignment Date. Assignor's obligations under this paragraph shall survive any
assignment of the Lease. Failure to complete the surrender the Premises in broom
clean condition and in the condition required under the Lease and the Assignment
or the performance of all of Assignor's obligations under this paragraph by the
Surrender Date shall constitute a holdover in the Premises without Landlord's
consent, and Assignor shall be subject to the provisions of Article 27 of the
Lease with respect to any period after the Surrender Date during which such
failure continues.  Landlord hereby confirms that the Turnover Date (as defined
in the Lease) has not occurred as of the date hereof.
2.            Consent.  Subject to the terms and conditions herein, Landlord
hereby (a) consents to the assignment of the Lease from Assignor to Assignee
effective as of the Assignment Date,  and (b) effective as of the Assignment
Date, forever releases and discharges Assignor from all obligations and
liabilities of the Tenant under the Lease to the extent accruing from or after
the Assignment Date, including without limitation the obligation to pay Base
Rent, Additional Rent and all other charges payable by Tenant under the Lease to
the extent accruing from and after the Assignment Date.  Notwithstanding the
foregoing, but subject to Section 22 of the Second Amendment to Lease, dated as
of [July , 2015] by and between Landlord and Assignee, Landlord does not waive,
and hereby expressly reserves, any rights and/or remedies that Landlord may have
under the Lease or at law or in equity arising from any default of Assignor
under the Lease occurring prior to or existing as of the Assignment. 
Notwithstanding anything to the contrary contained in the Lease, the Assignment
or this Landlord Consent, Landlord agrees that  the rights under Sections 9.8,
31.14 and 40 of the Lease may be and have been assigned in full from Assignor to
Assignee and shall hereafter be exercisable by Assignee in accordance with their
terms.
3.            Subsequent Assignment or Sublet.  Landlord's consent to the
foregoing Assignment shall not be construed as a waiver of Landlord's right to
consent to any subletting by Assignee or to any assignment by Assignee of its
rights, title, interest and obligations under the Lease, or as a consent to any
portion of the Premises being used or occupied by any other party, except as
expressly permitted pursuant to the terms of the Lease.
4.            Leasing Cost Payment.  In consideration of Landlord's consent to
the Assignment, on or before the date that is three (3) business days after the
Execution Date, Assignor shall pay to Landlord the amount of Eight Hundred
Ninety Three Thousand Six Hundred Eighty Seven Dollars ($893,687)  which is the
net of Two Million Two Hundred Seventy Two Thousand Nine Hundred Thirty Seven
Dollars ($2,272,937) (the "Leasing Cost Payment"), which Leasing Cost Payment is
the sum of (a) one-half (1/2) of the total leasing commissions due to Assignor's
and Assignee's brokers (the "Brokers") in connection with the Assignment, in the
amount of Three Hundred Seventy Five Thousand Six Hundred Thirty Six Dollars
($375,636) plus (b) a portion of the tenant improvement allowance to be paid by
Landlord to Assignee pursuant to a separate amendment to the Lease to be entered
into by and between Landlord and Assignee concurrently herewith (the "Lease
Assignment"), in the amount of One Million Eight Hundred Ninety Seven Thousand
Three Hundred One Dollars ($1,897,301),  minus One Million Three Hundred Seventy
Nine Thousand Two Hundred Fifty Dollars ($1,379,250) which reflects Landlord's
retention of Assignor's Security Deposit under the Lease. With respect to the
leasing commissions due to the Brokers, Landlord shall pay the Brokers all
commissions due under Assignor's exclusive listing agreement with Cushman and
Wakefield and all commissions due to CBRE and Landlord shall indemnify, hold
harmless and defend Assignor and Assignee from any and all claims and
liabilities arising from (i) Assignor's exclusive listing agreement with Cushman
and Wakefield or (ii) CBRE, whether arising out of Landlord's or Assignee's
brokerage agreement with CBRE.
5.            Confidentiality.  Neither Assignor nor Assignee shall reveal the
contents of the Assignment, except (a) as required by Applicable Laws or legal
process or to enforce the Party's obligations under the Assignment, or (b) to
each Party's affiliates, attorneys, accountants, auditors, employees,
principals, investors, partners, taxing authorities or agents or bona fide
prospective purchasers, assignees or subtenants, provided that any such
disclosure shall be on a need to know basis, as reasonably determined by the
applicable Party, and subject to the confidentiality obligations of this
Section, and further, provided that Assignee shall be entitled to make any
disclosure of the Assignment that Assignee, in its good faith judgment, believes
is required by Applicable Law or by any stock exchange on which its securities
or those of its affiliates are listed.
6.            Brokerage Commission.  Assignor and Assignee each represent and
warrant to Landlord that it has not dealt with any broker or agent other than
the Brokers in the negotiation for or the obtaining of this Assignment, and each
party agrees to reimburse, indemnify, save, defend and hold harmless Landlord
from and against any and all cost or liability for compensation claimed by any
broker or agent, other than Brokers, employed or engaged by it or claiming to
have been employed or engaged by the indemnifying party.
