preceding the Full Delivery Date (the “Preliminary Term”), Tenant
shall pay to Landlord “Tenant’s
Proportionate Share” (as defined below) of the Additional Rent (as defined in subparagraph
2D below). Tenant’s Proportionate Share of the Additional Rent shall be the percentage arrived
at by dividing the number of square feet of rentable area of the Premises as has been Delivered to
Tenant by 51,181 square feet (the “Tenant’s Proportionate Share”). Tenant’s




-3-









 







Proportionate Share shall be adjusted on a monthly basis (as of the first day of each calendar
month) as areas of the Premises are delivered to Tenant. All amounts due by Tenant to Landlord
during the Preliminary Term shall be paid within ten (10) days following Tenant’s receipt of a
bill therefor from Landlord. [As of the date of this Lease, Tenant’s Proportionate Share is one
hundred percent (100%).]




          B. Base Rent. Subject to the rent abatement provisions of the last sentence of this
subparagraph and subparagraph 4C of this Lease, commencing on the Full Delivery Date,
Tenant shall pay to Landlord Base Rent for the first Lease Year of One Million One Hundred
Seventy-Seven Thousand One Hundred Sixty-Three and No/100 Dollars ($1,177,163.00), payable in equal
monthly installments of Ninety Eight Thousand Ninety-Six and 92/100 Dollars ($98,096.92), the first
such installment being due on the Full Delivery Date (provided that if the Full Delivery Date is a
day other than the first day of a month, Base Rent for the month in which the Full Delivery Date
occurs shall be adjusted on the basis of a 30-day month) and the remaining installments being
payable, in advance, without notice, demand, deduction or set-off, on the first day of each and
every calendar month thereafter during the Lease Term. Notwithstanding the foregoing provisions of
this subparagraph, (i) Base Rent (but not Additional Rent) for the first six (6) months following
the Full Delivery Date (“Abatement Period”) shall be abated by an amount equal to fifty percent
(50%) thereof and shall be payable in monthly installments of Forty-Nine Thousand Forty-Eight and
46/100 Dollars ($49,048.46), and (ii) after the Abatement Period, Tenant shall be responsible for
the full Base Rent; provided, however, no Base Rent shall be due and payable for the Select Areas
until the date(s) each Select Area is Delivered to Tenant, with the Base Rent to be adjusted to
reflect Delivery of Select Areas on the first day of each calendar month to reflect a prior month’s
Delivery of part or




-4-









 







all of the Select Areas. [As of the date of this Lease all Select Areas have been Delivered to
Tenant and Tenant’s Abatement Period ends on July 18, 2007.]




          C. Increases in Base Rent. Commencing on February l, 2008, and continuing on the
first day of February in each succeeding year thereafter during the Lease Term, the Base Rent
payable by Tenant shall be increased by an amount equal to 2.125% multiplied by the Base Rent (as
adjusted pursuant to this subparagraph) payable during the last month of the immediately preceding
Lease Year.



          D. Additional Rent. On and after the Full Delivery Date, Tenant shall pay to
Landlord, as additional rent, an amount equal to (i) all amounts payable by Landlord with respect
to (a) that certain Declaration of Covenants, Easements and Restrictions (Protective Covenants)

Liber 15181 at folio 74 (the “Protective Covenants”) a copy of which is attached hereto and made a
part hereof as Exhibit E, (b) that certain Declaration of Covenants, Conditions, Easement
and Restrictions for The Johns Hopkins University Belward Research Campus dated September 24,

84 (the “Declaration”) a copy of which is attached hereto and made a part hereof as Exhibit

Agreement”), a copy of which is attached hereto and made a part hereof as Exhibit G, and
(ii) all other amounts payable by Tenant as set forth in this Lease, including, without
limitation, the Lease Addendum (such amounts are sometimes individually and collectively referred
to as “Additional Rent”). If any such amounts are payable by Landlord on a monthly basis, Tenant
shall likewise pay to Landlord such Additional Rent (upon presentation of an invoice for same or
delivery of notice of



-5-









 







such recurring charges), on a monthly basis, in addition to and on the same dates as the monthly
installments of Base Rent. Any Additional Rent not paid monthly shall be payable by Tenant to
Landlord within ten (10) days after receipt of a bill therefor from Landlord. Landlord shall
furnish Tenant with copies of statements setting forth the amount due from Tenant.



          E. Payment of Rent. Base Rent and Additional Rent (hereinafter collectively “Rent”)
shall be payable to Landlord, c/o Human Genome Sciences, Inc., 14200 Shady Grove Road, Rockville,
MD 20850, Attention; Chief Financial Officer, or to such other address as Landlord may from time to
time specify.



          F. Late Charges. Tenant shall pay to Landlord an amount equal to five percent (5%) of
any Rent not received by Landlord within five (5) days after such payment is due as compensation
to Landlord for its costs and inconvenience incurred as a consequence of Tenant’s delinquency.
Additionally, except as provided in subparagraph 8A of this Lease, all payments required
hereunder from Tenant which are not paid within five (5) days of the due date shall bear interest
from the date due until paid at an annual rate equal to the greater of (i) two percent (2%) per
annum in excess of the prime rate of interest published from time to time in the Wall Street
Journal Eastern Edition or (ii) twelve percent (12%) per annum. In no event, however, shall
the charges permitted hereunder or elsewhere in this Lease, to the extent they are considered to
be interest under applicable law, exceed the maximum lawful rate of interest.



     3. Security Deposit.



          A. Concurrent with the Initial Delivery Date, Tenant has paid to Landlord a security deposit
of Ninety-Eight Thousand Ninety-Six Dollars and Ninety-Two Cents ($98,096.92) (payable in cash or,
as and to the extent set forth in subparagraph B below, in the form of a letter of credit
reasonably acceptable to Landlord) (the “Security Deposit”).



-6-









 





          B. In lieu of depositing cash as the Security Deposit, Tenant shall have the right to deliver
to Landlord an unconditional, irrevocable, standby letter of credit in the amount of the cash
Security Deposit otherwise required hereunder, which letter of credit shall (i) be in a form
reasonably acceptable to Landlord, (ii) be issued by a financial institution selected by Tenant and
reasonably acceptable to Landlord, (iii) be for the benefit of Landlord, (iv) be payable by draft
sight in a location reasonably acceptable to Landlord upon presentation of a certification signed
by an officer of Landlord which states that an event of default has occurred under this Lease, and
(v) be payable in the event such letter of credit is not renewed on or before the date which is
thirty (30) days prior to its expiration. Any amounts of cash drawn on a letter of credit Security
Deposit will thereafter be treated as a cash Security Deposit hereunder.



          C. Tenant shall have the right at any time during the Lease Term upon thirty (30) days’ prior
written notice to Landlord (i) to replace a cash Security Deposit with a letter of credit which
complies with all the above terms of, or (ii) to replace a letter of credit Security Deposit with
a corresponding amount of cash or another letter of credit which complies with all the terms set
forth above.



          D. If Tenant fails to pay Rent when required or fails to perform any other covenant contained
herein following any notice and cure period provided herein, Landlord may use or retain all or any
part of the Security Deposit for the payment of any sum not so paid, or for the payment of any
amount which Landlord may spend or become obligated to spend by reason of Tenant’s default. If any
portion of the Security Deposit is so applied or used, then Tenant shall, within five (5) business
days after the effective date of written notice thereof, deposit an additional amount with
Landlord sufficient to restore said Security Deposit to the amount set forth above, or



-7-









 







replenish the letter of credit to the amount required hereunder, and Tenant’s failure to do so
shall constitute a default under this Lease.



          E. If Tenant has performed all of its monetary and other obligations hereunder (including, but
not limited to (i) radiological decommissioning of all laboratory and/or manufacturing suites
within the Premises in accordance with all applicable governmental requirements to the satisfaction
of all applicable governmental authorities (hereinafter referred to as “Decommissioning”), to the
satisfaction of Landlord; and (ii) decontamination of all “Hazardous Substances” (as defined in the
Lease Addendum), Biologics (as hereinafter defined) and all other potentially hazardous biological
materials in, on or about the Premises, other than with respect to Hazardous Substances referred to
in subparagraph 20D below, in accordance with the requirements of all applicable
governmental authorities and to the reasonable satisfaction of Landlord as demonstrated by an
environmental audit, satisfactory to Landlord in its reasonable discretion, performed at Tenant’s
cost (“Decontamination”) at the termination of this Lease, Landlord shall return said Security
Deposit or letter of credit to Tenant within sixty (60) days after termination of this Lease, less
any amounts required to restore the Premises to good condition and repair, reasonable wear and tear
and damage caused by casualty and condemnation excepted, including repairing any damage resulting
from the removal by Tenant of its Alterations (as defined below), trade fixtures or equipment.



     4. Delivery and Acceptance of Lease Premises.



          A. Upon satisfaction of the contingencies described in paragraph 31 below, the
office, laboratory and administrative portions of the Premises shown on Exhibit H attached
hereto and made a part hereof (collectively, the “Initial Delivery Areas”) shall be Delivered to
Tenant in the following condition: professionally cleaned and with all base building systems
servicing the



-8-









 







Premises in good repair and working order, and in a condition that will enable Tenant to obtain
maintenance contracts from contractors reasonably acceptable to Tenant and Landlord for
commercially reasonable prices covering such systems. In all other respects, the Initial Delivery
Areas are to be Delivered and subleased on an “AS IS, WHERE IS BASIS.” Tenant understands and
agrees that the laboratory suites which are part of the Initial Delivery Areas are subject to a
license issued by the State of Maryland for the handling and use of radioactive materials
(“License”); Landlord represents that it has requested that the License be amended to release such
laboratory areas thereby eliminating the requirement that the Landlord pursue and complete
Decommissioning with respect thereto, and such License amendment or Decommissioning, as the case
may be, shall be a condition precedent to Delivery of the initial Delivery Areas.



          B. Except for the Select Areas and the Initial Delivery Areas, the balance of the Premises,
as depicted and listed on Exhibit I and as depicted and listed on Schedule 1-A and 1-B (individually and collectively, the “Lab Areas”) shall be Delivered by Landlord in the same
condition as required of the Initial Delivery Areas and in accordance with the schedule attached
hereto and made a part hereof as Exhibit I. In all other respects, the Lab Areas are to be
Delivered and subleased on an “AS IS, WHERE IS BASIS.” Each date on which a portion of the Lab
Areas has been Delivered shall be a “Lab Premises Delivery Date”. A Lab Premises Delivery Date may
be extended for a Force Majeure event (as defined in the Lease Addendum) or for completion of any
required environmental clean-up. Tenant understands and agrees that the laboratory suites which
are part of the Lab Areas are subject to the License; Landlord covenants that on or before
December 22, 2006, it will request that the License be amended to release such laboratory areas
thereby eliminating the requirement that the Landlord pursue and complete Decommissioning with
respect thereto, and such License amendment or Decommissioning, as the case may be, shall be a
condition precedent to



-9-









 







Delivery to each portion of the Lab Areas. [As of the date of this Lease all Lab Areas have been
Delivered to Tenant and the aforesaid condition precedent (Landlord’s amendment of license or
Decommissioning) has been satisfied.]



          C. Those portions of the Premises labeled as areas B129L, B140L, B263L, B280L, B281 and B282
on Exhibit J (the “Select Areas”) shall be Delivered to Tenant within three (3) business
days following Landlord’s completion of all environmental remediation and Decommissioning
activities (which Landlord agrees to pursue in a timely manner and with all commercially reasonable
due diligence) and delivery to Tenant of copies of written evidence of acceptance of the completion
of said environmental remediation and Decommissioning (with respect to the Select Areas and, if
applicable, the other laboratory suites in the Premises which have not otherwise been removed from
the License) by the appropriate governmental authorities. The Select Areas shall be Delivered in
the same condition as required of the Lab Areas and shall be Delivered in stages as Landlord’s work
is completed within each of the Select Areas. If any portion of the Selected Areas is not Delivered
by the applicable date set forth in Exhibit J, Tenant shall provide written notice to
Landlord of such failure to Deliver and notwithstanding anything to the contrary contained herein,
Landlord shall have ninety (90) days after such notice to cure (“Cure Period”) such failure to
Deliver; and in the event any portion of the Select Areas is not Delivered by the expiration of the
Cure Period, then, in addition to the Base Rent for such non-Delivered Select Areas not commencing
pursuant to subparagraph 2B hereof Base Rent for the remainder of the Premises shall be
reduced by an amount equal to one hundred fifty percent (150%) of the daily rent applicable to such
non-Delivered Select Areas for each day following the Cure Period that such portion of the Select
Areas has not been Delivered, such daily rent to be calculated on the basis of a 30-day month at
the then applicable Base Rent for the entire Premises multiplied by a fraction, the numerator of



-10-









 







which shall be the square footage of the non-Delivered Select Areas and the denominator of which
shall be 51,181. [All Select Areas as of the date of this Lease have been timely Delivered.]



          D. Except as specifically set forth in this subparagraph 4D herein and except for the
work to be performed by Landlord pursuant to subparagraphs 4A, B and C above, Tenant
acknowledges that no warranties or representations concerning the condition, quality, or adequacy
of the Premises have been made to Tenant about the Premises. Landlord represents and warrants to
Tenant that (i) to the best of its knowledge, the Premises were constructed in compliance with all
requirements of the Americans with Disabilities Act (“ADA”), (ii) as of the Lease Commencement
Date, the Premises were in material compliance with all requirements of the ADA, (iii) to the best
of Landlord’s knowledge, as of the Lease Commencement Date, the Premises were in material
compliance with all governmental requirements, and (iv) Tenant is permitted to use the Premises for
its intended use for biological and pharmaceutical laboratories, research, development and
manufacturing and associated administrative uses under all applicable laws and regulations,
including, but not limited to applicable zoning laws and regulations.



          E. Other than as provided in subparagraph 4C, from and after the Full Delivery Date,
Tenant shall be solely responsible for the operation, maintenance and repair of the Premises in
accordance with the terms of this Lease.



          F. Intentionally Omitted.



     5. Lease Addendum. The Lease Addendum attached hereto as Exhibit A and made a
part hereof contains certain material and substantive terms and conditions of this Lease. Any
reference to “this Lease” or “the Lease” shall include the terms and conditions of the Lease
Addendum as if the same were fully set forth herein.



-11-









 





     6. Assignment and Subletting.



          A. Except as provided in subparagraphs 6B and 6C below, Tenant shall have no right to
sublet all or any part of the Premises nor shall Tenant have any right to assign or encumber this
Lease, without the prior written consent of Landlord, which consent shall not be unreasonably
withheld or delayed, but shall be subject to the conditions set forth in subparagraphs 6D and
6E below. No such assignment or subletting shall release or relieve Tenant from any
obligations under this Lease.



          B. Subject to satisfaction of the conditions set forth in subparagraphs 6D and 6E
below, but notwithstanding anything else to the contrary contained in subparagraph 6A,
Tenant may assign the Lease or sublet the Premises for any of the then remaining portion of the
unexpired Lease Term without Landlord’s consent except as hereafter expressly provided in (d)
below, but with prior written notice to Landlord: (i) to any parent, Affiliate (as hereinafter
defined) or subsidiary of Tenant, (ii) to a surviving person or entity in connection with the
merger, consolidation or acquisition between Tenant and any of its subsidiaries so long as the
Tenant’s parent as of the date of this Lease retains management control of the Tenant, or (iii) to
the purchaser of all or substantially all of Tenant’s assets or all of Tenant’s outstanding stock;
provided, however, that in the event of any such assignment or sublease: (a) Tenant to which the
Premises were initially leased shall continue to remain liable on the Lease for the performance of
all terms; (b) Tenant shall not be in default of any of the terms or provisions of the Lease beyond
any applicable notice and cure period(s); (c) any such sublessee or assignee shall assume in
writing, in a form acceptable to Landlord, all of Tenant’s obligations arising under this Lease;
and (d) Tenant and the proposed sublessee or assignee shall demonstrate to Landlord’s reasonable
satisfaction sublessee’s or assignee’s creditworthiness and financial capacity to meet all
subsequent financial obligations



-12-









 







arising under the Lease. Any of the permitted transfers hereinabove provided shall be permitted by
transfer of stock or any other ownership interests by Tenant or any parent of Tenant. “Affiliate”
shall mean any entity which is under common control with, controls or is controlled by the Tenant.



          C. Notwithstanding anything to the contrary contained herein, including, but not limited to,
subparagraph 6D below, no public offering of Tenant’s (or its parent’s) stock or other
ownership interests or the transfer of the stock or other ownership interests of Tenant or its
parent on a national securities exchange shall be deemed an assignment in violation of the Lease.



          D. Notwithstanding the foregoing, if at the time of the proposed assignment or subletting,
Landlord is a real estate investment trust (“REIT”) or is owned by an entity that is a REIT
(“Landlord’s REIT Entity”), then:



               (i) in the event the income generated by the proposed assignee or subtenant would jeopardize
Landlord’s REIT status or Landlord’s REIT Entity’s status, as a real estate investment trust
within the meaning of Sections 856 through 860 of the Internal Revenue Code of 1986 (“REIT
Status”) or cause Landlord or Landlord’s REIT Entity to be in receipt of income that does not
constitute “rent from real property” within the meaning of Section 856(d) of the Code, Tenant
shall be required to obtain Landlord’s prior written consent, which consent may be given or denied
in Landlord’s sole and absolute discretion; provided, however, in the event Tenant is unable to
determine whether the proposed assignment or sublease could jeopardize the Landlord’s REIT
Entity’s REIT Status, Tenant shall have the right to deliver a notice to Landlord, complying with
each of the requirements of subparagraph 6D(ii) hereof, requesting that Landlord make such
determination. Landlord shall notify tenant within five (5) business days after Landlord receives
such notice and such other information as Landlord may reasonably require whether such assignment
or sublease could jeopardize the Landlord’s REIT Entity’s REIT Status or cause Landlord or




-13-









 







Landlord’s REIT Entity to be in receipt of income that does not constitute “rent from real
property” within the meaning of Section 856(d) of the Code.




               (ii) In the event Landlord’s consent is required pursuant to this subparagraph 6D(i)
hereof, Tenant shall first notify Landlord of its desire to assign its interest in this Lease or
sublet the Premises and shall submit in writing to Landlord (the “Transfer Notice”); (a) the size
and location of the space Tenant proposes to assign or sublet; (b) the name of the proposed
assignee or subtenant; (c) the date on which the Tenant proposes that the transfer be effective,
which shall not be earlier than the date which is ninety (90) days after the Transfer Notice (d)
the nature of the proposed assignee’s or subtenant’s business to be carried on in the Premises; (e)
the terms and provisions of the proposed sublease or assignment; (f) such reasonable financial
information as Landlord may request concerning the proposed assignee or subtenant, and (g) such
other information as Landlord may reasonably require.



          E. Any proposed sublease or assignment shall meet the following requirements in
addition to any other requirements set forth above:



               (i) Landlord shall be provided with at least ninety (90) days written notice prior to the
effective date of any proposed assignment, subletting or other transfer;



               (ii) Any proposed assignee, sublessee or other transferee shall assume, in a written
instrument reasonably acceptable to Landlord, all of the obligations of Tenant hereunder;



               (iii) Any proposed assignee, sublessee or other transferee shall use the Premises for the
purposes set forth in Article 2 of the Lease Addendum;



               (iv) Tenant shall in no way be released from any of its obligations under this Lease; and



-14-









 





               (v) Tenant shall reimburse Landlord for legal fees and expenses reasonably incurred by
Landlord in connection with such approval, and the drafting and preparation of appropriate
documentation effectuating the assignment, subletting or other transfer.



     7. Default by Tenant; Remedies.



          A. If (i) default be made in the payment of Rent or any additional charge payable hereunder
by Tenant, and such default shall continue for five (5) days after written notice of default, or
(ii) default be made in any of the other covenants or conditions herein contained on the part of
Tenant and such default shall continue for twenty (20) days after written notice thereof shall
have been given to Tenant, (except that such 20-day period shall be automatically extended for an
additional period of time reasonably necessary to cure such default, if such default cannot be
cured within such first 20-day period and provided Tenant commences the process of curing such
default within said first 20-day period and continuously and diligently pursues such cure to
completion), or (iii) Tenant shall become insolvent or bankrupt or makes an assignment for the
benefit of creditors, or (iv) a receiver or trustee of Tenant’s property shall be appointed and
such receiver or trustee, as the case may be, shall not be discharged within sixty (60) days after
such appointment, then in any such case, Landlord may, without further notice to Tenant, notice
being hereby waived, terminate Tenant’s tenancy and recover possession of and reenter the Premises
without accepting a surrender of the Premises or affecting Tenant’s liability for past Rent and
other charges due or future rent and other charges to accrue hereunder. In the event of any such
default, Landlord shall be entitled to recover from Tenant, in addition to Rent and other charges
equivalent to rent, all other damages sustained by Landlord on account of the breach of this
Lease, including, but not limited to, the costs, expenses and attorney fees incurred by Landlord
in enforcing the terms and provisions hereof and in reentering and recovering possession of the
Premises and for the cost of repairs, alterations and




-15-











 




brokerage and attorney fees connected with the re-letting of the Premises, but excluding
consequential or incidental damages other than out-of-pocket expenses incurred by Landlord and
delineated herein. As an alternative, at the election of Landlord, Landlord shall have the right to
accept a surrender of the Premises (without the need for any affirmative act or acquiescence by
Tenant), without any further rights or obligations on the part of Landlord or Tenant (other than
Tenant’s obligation for Rent and other charges due and owing through the date of acceptance of
surrender), so that Landlord may re-let the Premises without any right on the part of Tenant to any
credit or payment resulting from any re-letting of the Premises. Alternatively, at the option of
the Landlord, if Tenant’s tenancy is so terminated, Landlord may recover forthwith against Tenant
as damages for loss of the bargain and not as a penalty an aggregate sum, which at the time of such
termination of Tenant’s tenancy, represents the amount of the excess, if any, of the value of the
whole balance of Rent, charges and all other sums payable hereunder for the entire balance of the
term of this Lease herein reserved or agreed to be paid by Tenant, over the then current fair
market rental value of the Premises (including “triple net” charges), such difference to be
discounted to net present value at the rate of eight percent (8%) per annum. In case of a default
under this Lease, Landlord may, in addition to terminating Tenant’s tenancy and/or accepting a
surrender, or in lieu thereof, pursue such other remedy or combination of remedies and recover such
other damages for breach of tenancy and/or contract as available at law or otherwise.




          B. In addition to the other remedies provided to each party under this Lease, each party is
entitled to all other remedies provided at law or in equity, including without limitation, to the
extent permitted by applicable law, injunctive relief in case of the violation, or attempted or
threatened violation, of any of the terms of this Lease, or to a decree compelling specific
performance of the terms of this Lease. No right or remedy of either party under this Lease is



-16-









 







intended to be exclusive of any other right or remedy. Each right and remedy of each party is
cumulative and may be exercised in addition to all other rights or remedies under this Lease, or
now or hereafter existing at law, in equity or by statute. The terms of this paragraph 7
shall survive termination or expiration of the Lease.



     8. Hold Harmless and Indemnities.



          A. From Tenant. To the fullest extent permitted by law, Tenant agrees to exonerate,
save harmless, protect and indemnify Landlord and its shareholders, officers, employees and agents
from and against any and all losses, damages, claims, suit, actions, judgments and costs (including
reasonable attorneys’ fees incurred in defending against any of the foregoing) to the extent caused
by the negligence or acts or omissions of, or use of the Premises by Tenant, its agents, officers,
invitees, employees or contractors. Tenant does hereby indemnify and hold harmless Landlord from
and against any loss, claim damages or expenses, (including reasonable attorney’s fees) which
Landlord may suffer, incur or expend arising out of any failure on the part of Tenant to fully
perform its obligations hereunder. Tenant shall reimburse and compensate Landlord for, as
Additional Rent, all expenditures made by, or damages, fines or costs (including reasonable
attorney’s fees) sustained or incurred by Landlord due to non-performance of, non-compliance with,
or breach of, or failure by Tenant to observe, any term, covenant or condition of this Lease on
Tenant’s part to be kept, observed, performed or complied with together with interest from the date
any such amounts are paid by Landlord, with interest at the lesser of twelve percent (12%) per
annum or the maximum lawful rate.



          B. From Landlord. To the fullest extent permitted by law, Landlord agrees to
exonerate, save harmless, protect and indemnify Tenant and its shareholders, officers, employees
and agents from and against any and all losses, damages, claims, suit, actions, judgments and
costs



-17-









 







(including reasonable attorneys’ fees incurred in defending against any of the foregoing) to the
extent caused by the negligence of Landlord with respect to acts or omissions occurring before the
Delivery of the entirety of the Premises, including all Select Areas (“Completed Delivery Date”)
or the gross negligence of the Landlord from and after the Completed Delivery Date or willful
misconduct of the Landlord, its agents, officers, invitees, employees or contractors, provided,
however, that Landlord shall in no event be liable to Tenant for any consequential damages, lost
profits, loss of business or loss of product. [The Completed Delivery Date is March 1, 2007.]



          C. Waiver of Subrogation. Anything in this Lease to the contrary notwithstanding,
Landlord and Tenant each hereby waives to the extent each is actually insured against the same any
and all rights of recovery, claim, action or cause-of action against the other for any loss or
damage that may occur to the Premises, or any improvements thereto, or any property of such party
therein, by reason of fire, the elements, or any other cause which could be insured against under
the terms of standard fire and extended coverage insurance policies, regardless of cause or origin,
including negligence of the other party hereto, its agents, officers or employees, and covenants
that no insurer shall hold any right of subrogation against such other party.



     9. Landlord’s Access to the Premises. Tenant agrees that it will allow the Landlord,
its agents or employees to enter the Premises at all reasonable times and upon reasonable prior
written notice (except in an emergency when no notice shall be required) to examine, inspect or
protect the same or to prevent damage or injury to the same or to make such alterations and
repairs to the Premises as the Landlord may deem necessary to comply with this Lease.
Notwithstanding the foregoing, except in the event of an emergency, Tenant may require that
Landlord be accompanied by a representative of Tenant during entry into certain portions of the
Premises.



-18-









 






     10. Survival. The provisions of paragraphs 3E, 5 (which shall include the
applicable provisions of the Lease Addendum), 7, 8, 11, 10, 12, 13, 16, 17, 20C, 20D, 20E, 23, 27
and 30 of this Lease and Tenant’s liability for all amounts due under this Lease shall survive
the termination of this Lease.



     11. Landlord’s Exclusions of Liability. Neither the Landlord, nor any of its
shareholders, officers, employees or agents, shall be liable for (i) loss or damage to any
property of Tenant, or of any entity within Tenant’s control, from any cause whatsoever other than
such loss or damage arising from Landlord’s negligence prior to the Completed Delivery Date or
gross negligence on or after the Completed Delivery Date or willful misconduct, (ii) any damage
referred to in clause (i) caused by other occupants or tenants of The Johns Hopkins University
Belward Research Campus or by construction, reconstruction or repair by Landlord or anyone acting
on Landlord’s behalf or with Landlord’s authority, or (iii) any latent defect in the Premises or
The Johns Hopkins University Belward Research Campus; and Tenant shall not be entitled to any
compensation for any of the above, or abatement of Rent or to any release from any of Tenant’s
obligations under this Lease, provided, however, that nothing herein provided shall preclude
Tenant from seeking the recovery of any actual damages (but not consequential damages, lost
profits, loss of business or loss of product) arising from Landlord’s negligence or gross
negligence, as the case may be, as hereinabove provided, willful misconduct or breach of any
express representation or warranty set forth in this Lease.



     12. Notices. Any notices or demands required or permitted to be given hereunder shall
be given to Landlord or Tenant, respectively, by (i) prepaid certified mail, return receipt
requested, or (ii) nationally recognized overnight delivery service. Notice shall be given to the

     13. Broker. Landlord and Tenant represent to the other that no broker or agent other
than Stream Realty Partners, L.P, and Scheer Partners, Inc. (“Brokers”) are entitled to a
commission or brokerage fee in connection with the Sublease and this Lease. Landlord shall be
responsible to pay all commissions or brokerage fees due to the Brokers pursuant to separate
agreement(s) between Landlord and Brokers. Each party agrees to indemnify and hold the other
harmless from and against any claim for any commissions, fees or other form of compensation by any
other broker claiming through the indemnifying party, including, without limitation, any and all
claims, causes of action,



-20-









 







damages, costs and expenses (including attorneys’ fees), associated therewith. The provisions of
this paragraph shall survive the termination of this Lease.



     14. Condemnation.



          A. If more than twenty-five percent (25%) of the Premises is taken or condemned for a
temporary or permanent public or quasi-public use (“Condemnation”), this Lease shall terminate at
the option of Landlord by notice delivered to Tenant within thirty (30) days of the Condemnation
and Tenant shall have no claim against Landlord for the value of any unexpired portion of the Lease
Term and shall not be entitled to any part of any award which may be made or to any damages
therefor, except that the Rent shall be adjusted as of the date of such termination. Tenant may
make a separate claim against the condemning authority for damages allowed by law provided that any
such award shall not reduce the amount otherwise payable to Landlord. Landlord has no obligation to
restore the Premises as a result of any condemnation or exercise of eminent domain. In the event of
a Condemnation which does not result in the termination of this Lease, Landlord and Tenant shall
agree to an equitable abatement of the Rent in proportion to the value of the Premises condemned.



          B. If less than twenty-five percent (25%) of the Premises is subject to a Condemnation and/or
no election has been made by Landlord to terminate this Lease, and subject to Landlord’s lender
making available to the Landlord award proceeds relating to such Condemnation for the purpose of
restoration of the Premises, then Landlord shall promptly commence and diligently pursue
restoration of the remainder of the Premises.



          C. In the event of a condemnation which renders the Premises substantially unfit for Tenant’s
then current use of same for offices, laboratory and/or manufacturing purposes, as the case may be
(“Functional Utility”), and either the Landlord shall have determined that Functional



-21-









 







Utility cannot be restored within one hundred eighty days (180) of such condemnation (“Condemnation
Restoration Period”), or if in fact Functional Utility is not restored within the Condemnation
Restoration Period, Tenant shall have the right to elect to terminate the Lease upon delivery of
written notice to Landlord. In the event Tenant exercises its right to terminate the Lease in
accordance with this subparagraph 14B, Rent (subject to such equitable abatement as shall
have previously been agreed to by the parties pursuant to subparagraph 14A, above) shall be
adjusted as of the date of such termination.



     15. Damage by Fire or Other Casualty.



          A. If more than twenty-five percent (25%) of the Premises shall be damaged by fire or other
casualty, Landlord may, at its option, terminate this Lease, in which case all obligations of the
parties shall be adjusted as of the date of such termination. Except as provided in the
immediately preceding sentence or in subparagraph 15B hereof, no damage or destruction of
the Premises shall be grounds for termination of this Lease or relieve Tenant from its obligations
arising hereunder, including, without limitation the Tenant’s obligations to pay Rent. If Landlord
has not terminated this Lease, Tenant shall, at Tenant’s sole cost and expense be responsible for
repairing and restoring all of the licensed FF&E (as defined below), all of Tenant’s improvements,
and for replacing any equipment and trade fixtures of Tenant located in the Premises.



          B. If less than twenty-five percent (25%) of the Premises shall be damaged by fire or other
casualty and/or there is no election to terminate this Lease in accordance with the terms hereof,
and subject to Landlord (i) obtaining approval of its mortgagee and (ii) thereafter advancing such
insurance proceeds to the Landlord, the Landlord will promptly commence and diligently pursue
restoration and repair of the Premises.



-22-









 





          C. Other than with respect to a casualty caused by Tenant, its agents, employees or invitees,
in the event of a casualty which renders the Premises substantially unfit for Tenant’s then current
use of same for offices, laboratory and/or manufacturing purposes, as the case may be, and either
the Landlord shall have determined that Functional Utility cannot be restored within one hundred
eighty (180) days of such casualty (“Casualty Restoration Period”), or if in fact Functional
Utility is not restored within the Casualty Restoration Period, Tenant shall have the right to
elect to terminate the Lease upon delivery of written notice to Landlord. In the event Tenant shall
have the right to terminate the Lease in accordance with this subparagraph 15B, Rent shall
be adjusted as of the date of such Tenant termination.



     16. Entire Agreement. This Lease contains the entire agreement between the parties
relating to the Premises and cannot be modified or terminated except by written instrument signed
by the parties hereto. No representations, understandings or agreements have been made or relied
upon in the making of this Lease other than those specifically set forth herein.



     17. Waiver of Jury Trial. Landlord and Tenant waive trial by jury in any proceeding
or any matter in any way connected to this Lease.



     18. Intentionally Omitted.



     19. Rules and Regulations. Tenant will comply with all rules and regulations
contained in the Lease and/or which may be hereafter promulgated by Landlord, and shall comply
with all of the terms and provisions contained in the Protective Covenants, the Declaration and
the Easement Agreement. Landlord has no obligation to assure that other tenants and invitees of
The Johns Hopkins University Belward Research Campus comply with any of the foregoing.



-23-









 





     20. Hazardous Substances.



          A. Except for the work required to be performed by Landlord pursuant to subparagraph
4C above and except as specifically set forth in this Lease, Landlord makes no warranties or
representations of any type regarding (i) the environmental condition of the Premises or The Johns
Hopkins University Belward Research Campus, or (ii) the presence or absence therein or thereon of
any Hazardous Substances. Landlord represents to Tenant that neither Landlord, nor its agents,
employees or contractors has used, handled or manufactured within the Premises any penicillins or
cephalosporins.



          B. Landlord acknowledges that Tenant will be using, storing or generating the Hazardous
Substances listed on Exhibit K-1 and the potentially hazardous biological materials
identified in Exhibit K-2 (“Biologics”). Tenant agrees that all such Hazardous Substances,
Biologics and all other potentially hazardous biological materials brought onto the Premises by or
for the Tenant will be stored, used, generated and disposed of in strict compliance with all
applicable laws, rules, regulations and ordinances of any governmental or quasi-governmental
authority having jurisdiction over the Premises. Tenant shall obtain, at Tenant’s sole cost, all
permits required by governmental authorities for the storage, use and generation of Hazardous
Substances, Biologics and all other potentially hazardous biological materials used in, on or
about the Premises, Tenant shall update Exhibits K-1 and K-2 on August 1 and February 1 of
each year during the Lease Term, as the same may be extended.



          C. Tenant agrees to indemnify, defend and hold harmless Landlord and its employees, agents,
successors and assigns, from and against any and all damage, claim, liability, or loss, including
reasonable attorneys’ and other fees, arising out of or in any way connected to Tenant’s
generation, treatment, storage or disposal of Hazardous Substances, Biologics and all other



-24-









 







potentially hazardous biological material. Such duty of indemnification shall include, but not be
limited to damage, liability or loss pursuant to all federal, state and local environmental laws,
rules and ordinances, strict liability and common law.



          D. Landlord agrees to indemnify, defend and hold harmless Tenant, its employees, agents,
successors and assigns, from and against any and all damage, claim, liability, or loss, including
reasonable attorneys’ and other fees, arising out of or in any way connected to the generation,
treatment, storage or disposal of Hazardous Substances by Landlord, its employees, agents,
contractors or invitees in, on or near the Premises prior to the Full Delivery Date, except for any
Hazardous Substances introduced by Tenant after the Initial Delivery Date. Such duty of
indemnification shall include, but not be limited to damage, liability or loss pursuant to all
federal, state and local environmental laws, rules and ordinances, strict liability and common law.



          E. Each party agrees to promptly notify the other of any disposal of Hazardous Substances in,
on or near the Premises, or any discovery of Hazardous Substances on or near the Premises, or of
any notice by a governmental authority or private party alleging or suggesting that a disposal of
Hazardous Substances on or near the Premises may have occurred.



          F. Tenant agrees to promptly notify the Landlord of any notice by a governmental authority or
private party alleging or suggesting that an impermissible disposal of Biologies or any other
potentially hazardous biological materials on or near the Premises may have occurred.



     21. Insurance. Tenant, at its sole cost and expense, shall maintain insurance as
required under Article 6 of the Lease Addendum, and, in addition, prior to the
commencement of any manufacturing activities on, in or about the Premises Tenant shall obtain and
thereafter maintain an environmental insurance policy in an amount and insuring such risks as
shall be commercially



-25-









 







reasonable with respect to Tenant’s use and occupancy of the Premises. Tenant shall insure the FF&E
(as hereinafter defined) for its full replacement value. Tenant shall include Landlord as an
additional insured and loss payee on all such insurance required to be maintained by Tenant.
Evidence of such insurance shall be furnished to Landlord prior to the Initial Delivery Date, with
respect to the Initial Delivery Areas, the Full Delivery Date with respect to the Lab Areas and
within three (3) business days after Delivery of each of the Select Areas, and shall be
satisfactory to the Landlord in its reasonable discretion. Not less frequently than annually during
each Lease Year, Tenant shall provide Landlord with evidence, reasonably satisfactory to Landlord,
that all insurance required of Tenant hereunder remains in full force and effect.



     22. Subordination. Subject to delivery of a non-disturbance agreement in a form
reasonably acceptable to Tenant, this Lease is subject and subordinate to all ground or underlying
leases and to all mortgages and/or deeds of trust which may now or hereafter affect this Lease or
the Premises, and to all renewals, modifications, consolidations, replacements and extensions
thereof. This clause shall be self-operative and no further instrument of subordination shall be
required by any mortgagee, trustee or ground lessor. In confirmation of such subordination, Tenant
shall, at the request of Landlord or any party secured by any such mortgage, deed of trust or
ground lease, promptly execute, acknowledge and deliver an instrument that has for its purpose and
effect the subordination of this Lease, provided the same contains non-disturbance language
materially the same as set forth in Schedule 3 to this Lease. Tenant hereby constitutes
and appoints Landlord the Tenant’s attorney-in-fact to execute any such certificate or
certificates referenced in this paragraph 22 for and on behalf of the Tenant, provided the
same contains non-disturbance language materially the same as the SNDA referred to in
subparagraph 31B of this Lease, in the event the Tenant fails or refuses within five (5)
business days following a written request to execute a Lease subordination



-26-









 







agreement in said form. Landlord represents and warrants that to the best of its actual knowledge,
that there are no ground or underlying leases or mortgages or deeds of trust affecting the
Premises as of the date hereof, and Landlord further represents and warrants that there are no
mortgages, security interests or subleases affecting the Landlord’s interests in the FF&E or this
Lease as of the date hereof.



     23. Holding Over. If Tenant shall hold over after the expiration of the term of this
Lease, Tenant shall become a tenant by the month, and, during Tenant’s period of unauthorized
occupancy, Tenant shall be liable for, and shall pay to Landlord, 250% of the monthly installment
of Base Rent then in effect for the month immediately prior to the expiration of the Lease Term,
and the amount of any Additional Rent payable by Tenant pursuant to the terms of this Lease. In
addition, Tenant shall be liable for, and shall promptly reimburse Landlord for all costs incurred
by Landlord in connection with Tenant’s holding over to the extent not otherwise recoverable under
the preceding sentence. If Landlord shall desire to regain possession of the Premises promptly at
the expiration of the Lease Term, as the same may have been extended, then at any time prior to
Landlord’s acceptance of Rent from Tenant as a monthly tenant hereunder, Landlord, at its option
may, forthwith re-enter and take possession of the Premises without process, or by any applicable
legal process. For purposes of this paragraph 23, the Tenant shall be deemed to have held
over beyond the expiration of the Term of this Lease if the Tenant has not completed all requisite
Decommissioning in conjunction with any governmental licenses issued to Tenant in connection with
its use and occupancy of the Premises and all Decontamination as provided in subparagraph
3E hereof.



     24. Americans With Disabilities Act. From and after the Initial Delivery Date, Tenant
shall be responsible for compliance with the Americans with Disabilities Act of 1990, as the same
may be amended, relating to Tenant’s use or occupancy of the Premises.



-27-









 





     25. Representations. Landlord and Tenant each acknowledge that their respective
officers executing this Lease have been duly authorized to do so and to bind their respective
company.



     26. Renewal Options. Provided Tenant is not in default under this Lease beyond any
applicable notice and cure period, Tenant has the option to renew the Lease Term for two (2)
additional periods of three (3) years each and a third option to renew the Lease Term until March
30, 2021, each option exercisable upon not less than nine (9) months prior written notice to
Landlord given prior to the expiration of the initial Lease Term or the then applicable extension
period, whichever is applicable. If this Lease is so renewed, the Base Rent for each extension
period shall continue to increase by 2.125% as set forth in subparagraph 2C above. All
other terms and provisions of this Lease shall govern each extension period, except that upon each
such extension Tenant shall have one (1) less option to extend the Lease Term. Notwithstanding the
foregoing, if Tenant is then in default under the provisions of this Lease beyond any applicable
notice and cure period at what would have been the commencement date of the then applicable
extension period, or if Tenant fails to timely give its notice to extend the Lease Term, Tenant’s
option to renew shall be null and void and of no further force or effect.



     27. Signage. Tenant may install, affix or use any signs or other advertising or
identifying media to the exterior of the Building or within the Premises; provided that: (i) such
signage does not materially adversely affect the structural integrity of the Premises; (ii) any
and all signs and other advertising or identifying media installed, affixed or used by Tenant upon
the Premises shall comply with any and all governmental laws, regulations, ordinances and rules
and all recorded restrictions and covenants; and (iii) Tenant shall prior to the scheduled
termination of this Lease or within thirty (30) days after the earlier termination of this Lease
cause all such signage to be removed and shall



-28-









 







restore the Premises to its condition prior to installation of such signage and repair any damage
to the Premises caused by such removal.



     28. Counterparts; Telefacsimile Execution. This Lease may be executed in any number of
counterparts, and by each of the parties on separate counterparts, each of which, when so executed,
shall be deemed an original, but all of which shall constitute but one and the same instrument.
Delivery of an executed counterpart of this Lease by telefacsimile shall be equally as effective as
delivery of a manually executed counterpart of this Lease. Any party delivering an executed
counterpart of this Lease by telefacsimile shall also deliver a manually executed counterpart of
this Lease, but the failure to deliver a manually executed counterpart shall not affect the
validity, enforceability or binding effect of this Lease.



     29. Parking. The parking area of the Premises consists of 134 parking spaces, and
Tenant shall have use of all of such spaces.



     30. License to Use Furniture, Fixtures and Equipment. During the Lease Term and in
the absence of a default under the Lease beyond any applicable notice and cure period, Tenant
shall have a license to use the furniture, fixtures and equipment (“FF&E”) owned by Landlord and
located within the Premises, which FF&E is listed on Exhibit L attached hereto and made a
part hereof. Tenant shall, at Tenant’s sole cost and expense, keep the FF&E in the same order and
condition as on the Lease Commencement Date, and shall repair and maintain the FF&E. Unless the
license to use all or part of the FF&E is revoked by Landlord prior to the Lease Expiration Date,
as a result of a Tenant default under this Lease beyond any applicable notice and cure period,
Tenant shall return all FF&E to Landlord at the expiration or earlier termination of this Lease in
the same order and condition it was in at the Lease Commencement Date, reasonable wear and tear
and loss or damage



-29-









 







by casualty or condemnation (provided Landlord has received insurance or condemnation proceeds
relating to same) excepted.



     31. Intentionally Omitted.



     32. Capitalized Terms. Except as defined herein, capitalized terms used herein shall
bear the same meaning ascribed to them in the Lease Addendum.



     33. Time of the Essence. Time is of the essence of each provision of this Lease.



     34. No Construction Against Drafting Party. The rule of construction that ambiguities
are resolved against the drafting party shall not apply to this Lease.



     35. Governing Law. The terms of this Lease shall be governed in accordance with the
laws of the State of Maryland.



     36. Interpretation. If any provision of this Lease or application thereof to any
person or circumstance shall, for any reason and to any extent, be invalid or unenforceable, the
remainder of this Lease and the application of that provision to other persons or circumstances
shall not be affected but rather shall be enforced to the extent permitted by law. The captions,
headings and titles, if any, in this Lease are solely for convenience of reference and shall be
construed without regard to any presumption or other rule requiring construction against the party
causing this Lease to be drafted. Any words or phrases in this Lease shall be construed as if the
words or phrases so stricken out or otherwise eliminated were never included in this Lease and no
implication or inference shall be drawn from the fact that said words or phrases were so stricken
out or otherwise eliminated. Each covenant, agreement, obligation or other provision of this Lease
shall be deemed and construed as a separate and independent covenant of the party bound by,
undertaking or making same, not dependent on any other provision of this Lease, unless otherwise
expressly provided. All terms and words used in this Lease, regardless of the number or gender, in
which they are used, shall




-30-











 




be deemed to include any other number and other gender as the context may require. The word
“person” as used in this Lease shall mean a natural person or persons, a partnership, a corporation
or any other form of business or legal association or entity. References to paragraphs and
subparagraphs shall mean the paragraphs and subparagraphs of this Lease unless the context clearly
requires otherwise.




     37. Recitals, Exhibits and Schedules. The recitals set forth above, and the Exhibits
and Schedules attached hereto, are material and substantive parts of this Lease and are
incorporated herein by this reference.



     38. Binding Effect. The covenants, agreements and obligations set forth in the Lease
and the Lease Addendum, except as herein otherwise specifically provided, shall extend to, bind
and inure to the benefit of the parties here to and their respective personal representatives,
heirs, successors and assigns (but in the case of assigns only to the extent that assignment is
permitted hereunder). No third party, other than such successors and assigns, shall be entitled to
enforce any or all of the terms of this Lease or Lease Addendum or shall have rights hereunder or
thereunder whatsoever.

EXHIBIT A




LEASE ADDENDUM




     THIS LEASE ADDENDUM is dated as of even date with, and is attached to and made part of, that
certain Lease Agreement dated of even date by and between GP ROCK ONE, L.L.C., a Rhode Island
limited liability company, as Landlord, and NOVAVAX, INC., a Delaware corporation, as Tenant,
regarding those certain Premises located at 9920 Belward Drive, Rockville, Maryland 20850, as more
fully described in the said Lease Agreement. References in the Lease or in this Lease Addendum to
“this Lease” or “the Lease” shall be deemed to include the terms and conditions of this Lease
Addendum.



Article 1. Taxes. Throughout the term of this Lease and any extension, Tenant shall pay,
as Additional Rent, all taxes, charges and assessments, general and special, ordinary and
extraordinary, of every nature and kind whatsoever, and all water rates and sewage or sewer use
charges levied, assessed or imposed upon the Premises or any portion thereof, whether such tax,
rate, charge or assessment shall be for village, town, county, state, federal or any other purpose
whatsoever, Tenant hereby covenanting to pay taxes and assessments upon the real estate as well as
upon the improvements thereon and the personal property used in connection with the operation of
the Premises (collectively, the “Taxes” and separately, a “Tax”), but only to the extent the Taxes
arise during and relate to the term of this Lease. Such Taxes shall include, without limitation,
all general real property taxes and general, special and area-wide assessments, charges, fees,
assessments for transit, police, fire or other governmental services or purported benefits to the
Premises, service payments in lieu of or in addition to real estate taxes, and any tax, fee or
excise on the act of entering into this Lease or on the use or occupancy of the Premises or any
part thereof or on the rent payable under this Lease or in connection with the business of renting
the Premises (other than Landlord’s income and/or franchise taxes), that may be now or may
hereafter be levied or assessed against the Premises or Landlord by the United States of America,
the State of Maryland, Montgomery County, or any political subdivision, public corporation,
district or other political or public entity. Should any governmental agency or political
subdivision impose any taxes and/or assessments, whether or not now customary or within the
contemplation of the parties hereto, either by way of substitution for taxes and assessments
presently levied and assessed against the real estate as well as the improvements thereon, or in
addition thereto, including, without limitation, any taxes based upon the rentals received by
Landlord hereunder (other than an income or franchise tax), such taxes and/or assessments shall be
deemed to constitute a Tax for the purpose of this Article 1 and shall be paid by Tenant.
Taxes payable by Tenant hereunder shall also include reasonable costs, disbursements and legal
fees of Landlord incurred in connection with proceedings to contest, determine or reduce any such
taxes, charges or assessments; provided that, so long as Tenant is not in default under this
Lease, Landlord shall not commence any such contest or proceeding without the consent of Tenant,
which consent shall not be unreasonably withheld. Tenant shall furnish to Landlord a receipted tax
bill and other satisfactory evidence of the payment of such taxes, assessments and charges within
ten (10) days after the same are due and payable. Tenant’s obligations under this Article
1 shall survive the expiration or earlier termination of the Lease. Landlord shall promptly
upon its receipt furnish Tenant with copies of all proposed assessments and final bills for all
Taxes.

Lease Addendum









 





          1.1. Escrow for Taxes. If required by Landlord’s mortgagee at any time after a
default by Tenant in the payment of Base Rent, taxes or any other monetary obligation under this
Lease, Tenant thereafter shall pay all Taxes accruing during the term hereof to Landlord in
monthly installments on or before the first day of each calendar month, in advance, in an amount
estimated by Landlord’s mortgagee. Upon receipt of all statements for Taxes due for a calendar
year, Landlord shall submit to Tenant a written statement of the actual amount of the Taxes for
such year and the amount, if any, then paid by Tenant. If the total amount paid by Tenant under
this Article 1.1 for any year shall be more or less than the actual amount due from Tenant
for such year, as shown in such statement, either Tenant shall pay to Landlord the shortfall
within ten days after receipt of the statement or such excess shall be credited against the next
installment of Taxes due from Tenant to Landlord hereunder, as the case may be. All amounts due
hereunder shall be payable to Landlord at the place where the rental is payable and shall be held
in an interest bearing account for the benefit of Tenant with a financial institution designated
by Landlord’s mortgagee. A copy of a Tax bill submitted by Landlord to Tenant shall at all times
be sufficient evidence of the amount of Taxes levied, assessed or imposed against the Premises to
which such bill relates. Landlord’s and Tenant’s obligations under this Section shall survive the
expiration of the Lease Term. In the event of any default by Tenant hereunder, any such deposits
may be used by Landlord to cure the default, but Landlord shall be under no obligation to do so
and Tenant shall have no authority to direct Landlord to apply such deposits against any
obligation of Tenant hereunder.



          1.2. Right to Contest. Tenant may contest in good faith by appropriate proceedings at
its own expense any Taxes provided that Tenant shall first have paid such Taxes or, if the payment
of such Taxes is to be postponed during the contest, shall have furnished Landlord with a bond of a
surety company reasonably satisfactory to Landlord in an amount equal to, or shall have deposited
with any bank or trust company of Landlord’s selection in the State wherein the Premises are
located to hold such deposit and apply the same as hereinafter provided, the amount of the Taxes so
contested, together with such additional sums as may reasonably be required to pay interest or
penalties accrued or to accrue on any such Taxes. Nothing contained herein, however, shall release
Tenant of the obligation to pay and discharge contested Taxes as finally adjudicated, with interest
and penalties, and all other charges directed to be paid in or by any such adjudication. Any such
contest or legal proceeding shall be begun by Tenant as soon as reasonably possible after the
imposition of any contested Taxes and shall be prosecuted to final adjudication with all reasonable
promptness and dispatch; provided, however, that Tenant may in its discretion consolidate any
proceeding to obtain a reduction in the assessed valuation of the Premises for tax purposes
relating to any tax year with any similar proceeding or proceedings relating to one or more other
tax years. Notwithstanding anything contained herein to the contrary, Tenant shall pay all such
contested items before the time when the Premises or any part thereof might be forfeited as a
result of nonpayment.



          1.3. Landlord’s Cooperation. Landlord shall join in any proceedings referred to in
Article 1.2 and hereby agrees that the same may be brought in its name, if the provisions
of any law, rule or regulation at the time in effect shall so require. Tenant shall indemnify and
save Landlord harmless from any liabilities, losses, or expenses (including reasonable attorneys
fees) in connection with any such proceedings in which Landlord shall join or permit to be brought
in its name. So long as Tenant is not in default under any term or condition of this Lease, (i)
Tenant shall be entitled to any refund of any Taxes, and all penalties or interest thereon
received by Landlord which shall have



Exhibit A; page -2-
Lease Addendum









 







been paid by Tenant, or which shall have been paid by Landlord but previously reimbursed in full by
Tenant and (ii) Landlord shall not, without Tenant’s prior written approval (which shall not be
unreasonably withheld), agree to any settlement, compromise or other disposition of any such
proceedings or discontinue or withdraw from any such proceedings or accept any refund of any Taxes
as a result of any such proceedings.


Article 2. Use of Premises. Tenant shall not use or allow the Premises to be used for any
improper or unlawful purpose or for any purpose which could violate any recorded covenant or
restriction affecting the Premises. Tenant shall not cause or maintain or permit any nuisance or
commit or suffer the commission of any waste in, on or about the Premises. Tenant may install on
the Premises such trade fixtures and equipment as Tenant deems necessary for its business
activities; provided that the installation and use of all such trade fixtures and equipment shall
be in compliance with any and all applicable governmental laws, rules, regulations and ordinances
and no such trade fixture or equipment shall be affixed to the exterior of the Building or in any
manner which affects the roof or structural components of the Building without the prior written
consent of Landlord which consent shall not be unreasonably withheld, conditioned or delayed. Title
thereto shall remain in Tenant, even though such equipment may be affixed to the Premises. On
termination of this Lease, the removal of such property is governed by Article 9 of this
Lease Addendum. Except for as represented by Landlord in the Lease, Tenant acknowledges and agrees
that it has made its own independent investigation to confirm that the Tenant’s use of the Premises
for office and laboratory operations will comply with all applicable covenants and restrictions and
all applicable governmental codes, rules and regulations in effect as of the execution of this
Lease. Notwithstanding the foregoing, Tenant may plan, design, construct, supervise and maintain
upon the roof and/or the exterior of the Building any antennas, satellite dishes and similar
communications facilities, provided that the same (i) do not impair the structural integrity of the
Building, (ii) does not void or impair any roof warranty for the Building that has been provided in
writing to Tenant, and (iii) complies with all applicable governmental codes, ordinances, rules,
regulations and laws. Any such facility which shall be so installed or erected shall, unless and
until Tenant shall remove the same, be maintained by Tenant at Tenant’s own cost and expense and
any damage to the Premises caused by the removal thereof shall be repaired, at Tenant’s expense,
upon the expiration or earlier termination of the term of this Lease.



Article 3. Repairs/Operating Expenses. Throughout the Lease Term, Tenant shall keep the
Premises in good condition and repair and be responsible for all costs of operating the Premises
and all maintenance, repairs and replacements to the Premises, structural and nonstructural,
ordinary or extraordinary, foreseen or unforeseen, including, but not limited to, all structural
repairs and replacements to the foundation, exterior and/or load bearing walls, roof, and
mechanical systems of the Premises and all landscaping, sidewalks and parking areas contained in
or about the Premises, and all common area and easement expenses and assessments, including, but
not limited to, all assessments imposed on the Premises under the covenants and restrictions for
the Johns Hopkins Belward Campus Biotechnology Park and/or any easement agreement appurtenant to
the Premises. Tenant shall pay any and all such assessments and charges as and when due and shall
make all such repairs and replacements as may be necessary to maintain the Premises in a condition
consistent with other first class office/laboratory (and if altered in accordance with Article
5 of this Addendum, biomedical manufacturing) buildings located in the State of Maryland,
provided that Tenant shall not





Exhibit A; page -3-
Lease Addendum









 







be required to provide or install upgraded building improvements of a scope or quality greater than
the scope and quality of the original Building. Tenant shall keep the Premises in a clean, safe,
sanitary and tenantable condition in a manner compatible with its intended use, shall not permit
any garbage, waste, refuse or dirt of any kind to accumulate in or about the Premises, shall keep
all drives, parking areas, entrances and pedestrian walkways reasonably free from snow and ice and
shall make any repairs, replacements or improvements which may be required by any laws, rules,
regulations, ordinances or orders of any federal, state, local or other governmental authority
having jurisdiction over the Premises. Tenant shall further use all reasonable precaution to
prevent waste, damage or injury to the Premises. Notwithstanding the foregoing, Tenant shall not be
required to replace any component of the Improvements during the last twelve (12) months of the
Lease term (including any extension options which have been exercised by the Tenant); provided that
Tenant shall maintain the Improvements and surrender the Improvements and all building systems at
the end of the term of this Lease in good operating condition.



Article 4. Utilities. Throughout the term hereof, Tenant shall be responsible for and
shall promptly pay as and when due all charges for heat, water, gas, electricity and sanitary
sewer charges, as well as any charges for any other utility used or consumed in, on or upon the
Premises. Tenant shall at all times keep the Premises sufficiently heated so as to prevent
freezing and deterioration thereof and/or of the equipment and facilities contained therein.



Article 5. Alterations. Except as otherwise expressly provided in this Article 5,
Tenant shall not make or suffer to be made, any alterations, additions or improvements to the
Premises (each an “Alteration” and collectively, the “Alterations”), in excess of One Hundred
Thousand Dollars ($100,000.00) for any single Alteration, or in excess of Two Hundred Fifty
Thousand Dollars ($250,000.00) in the aggregate for all Alterations within a twelve (12) month
period or which affect the structural or mechanical components of the Premises in, on or to the
Premises or any part thereof without the prior written consent of Landlord, which consent shall not
be unreasonably withheld, conditioned or delayed; Landlord’s consent to any Alterations for which
Landlord’s consent is required hereunder shall be contingent upon Tenant agreeing to the following
minimum conditions:




          5.1. Cost. Tenant shall pay or cause to be paid the entire cost of the
Alterations;



          5.2. Plans. Plans and specifications for all Alterations shall be submitted to
Landlord for prior written approval, which approval shall not be unreasonably withheld;



          5.3. Liens.
Tenant shall take all necessary steps to prevent the imposition of liens
against the Premises as a result of the Alterations;



          5.4. Indemnity. Tenant shall agree to hold Landlord harmless from all claims, losses,
liabilities, damages, and expenses (including reasonable attorneys, fees) resulting from any
Alterations; and



          5.5. Permits. Tenant shall obtain and pay for all necessary permits and shall comply
with all applicable governmental requirements and insurance rating bureau recommendations.




Exhibit A; page -4-
Lease Addendum









 







Notwithstanding the foregoing, in the event that Novavax desires to convert a portion of the
Premises for use as biomedical manufacturing facilities, any alterations in connection therewith
shall be subject only to the requirements of subsections 5.1 through 5.5.



Provided that Landlord incurs no additional responsibility, cost or liability for the removal
and/or restoration of any Alterations made by Tenant, during the Lease Term, Tenant shall have the
right to remove, modify and/or relocate any and all existing Alterations made by Tenant and
fixtures and equipment owned by Tenant provided that (i) Tenant repairs any damage caused by such
removal and (ii) the Premises shall be delivered to Landlord in good repair and working order,
normal wear and tear excepted. At the termination of the Lease Term, removal of Alterations made by
Tenant and fixtures and equipment owned by Tenant shall be governed by Article 9 of this
Lease Addendum.



Article 6. Insurance.




          6.1. Liability Insurance. Tenant shall, during the entire term hereof, keep in full
force and effect a policy of comprehensive general public liability insurance with respect to the
Premises, and the business operated by Tenant in the Premises, in which the primary coverage per
accident or occurrence is not less than $1,000,000 combined single limit and the umbrella coverage
per accident or occurrence is not less than $10,000,000, or in such greater amounts as Landlord
may reasonably determine in accordance with prudent business practices.



          6.2. Property Insurance. Tenant agrees to carry, at its expense, property insurance
insuring against fire, vandalism, malicious mischief, and such other hazards as are from time to
time included in a standard extended coverage endorsement, insuring the Premises in an amount
equal to the full replacement value of the Premises (with an agreed amount endorsement, excluding
land value, landscaping, foundation and excavation costs, and costs of underground flues, pipes
and drains), together with rental interruption insurance in an amount equal to twelve (12) months
fixed base rental and real estate tax payments, and insuring the betterments and improvements made
by it to the Premises, and all trade fixtures, furnishings and equipment owned by Tenant and
located on or within the Premises, in an amount equal to the full replacement value thereof.



          6.3. Requirements. The policies required under this Article 6.3 shall name
Tenant and Landlord and any other parties in interest designated by Landlord as insureds as their
respective interests may appear, and shall contain a clause that the insurer will not cancel or
change the insurance without first giving the Landlord thirty (30) days prior written notice. Such
insurance may be furnished by Tenant under any blanket policy carried by it or under a separate
policy therefor. The insurance shall be with carriers with a Best financial quality rating of A or
better and a financial size rating of XII or better. A copy of the paid-up policies or
certificates of the insurers evidencing the maintenance of such insurance policies shall be
delivered to Landlord prior to commencement of the term of this Lease or Tenant’s occupancy,
whichever is sooner, and, upon renewals, prior to the expiration of a coverage period. All such
policies shall be written as primary policies, not contributing with and not in excess of the
coverage that Landlord may carry. Tenant agrees that if

Lease Addendum









 







Tenant does not take out and maintain insurance, Landlord may (but shall not be required to)
procure said insurance on Tenant’s behalf and at its cost to be paid by Tenant as additional rent.



Article 7. Intentionally Omitted.



Article 8. Right to Cure; No Waiver, Accord or Satisfaction. In addition
to the parties’ respective rights and remedies under paragraph 7 of the Lease, the following
provisions shall apply:




          8.1. Landlord’s Right to Cure. All covenants and agreements to be performed by the
Tenant under any of the terms of this Lease shall be performed by Tenant at Tenant’s sole cost and
expense and without any abatement of Rent. If the Tenant shall fail to pay any sum of money
required to be paid by it hereunder, other than Rent, or shall fail to perform any other act on its
part to be performed hereunder, and such failure shall continue past any period of notice or cure
provided under paragraph 7 of the Lease, the Landlord may, but shall not be obligated to,
cure such default, without waiving or releasing the Tenant from any other default by Tenant under
this Lease. All sums so paid by the Landlord and all necessary incidental costs (including
reasonable attorney’s fees) incurred by Landlord in enforcing any of the terms, covenants or
conditions of this Lease, or curing any default or in suing for or obtaining relief by reason of a
breach thereof, together with interest on all of the foregoing at the rate set forth in
subparagraph 2F of the Lease from the date of payment by the Landlord, shall be payable as
Additional Rent to the Landlord on demand. Landlord shall have, in addition to any other right or
remedy of the Landlord, the same rights and remedies in the event of the nonpayment thereof by the
Tenant as in the case of default by the Tenant in the payment of Rent.



          8.2. Tenant’s Right To Cure. If Landlord fails to perform or observe any of the
obligations on Landlord’s part to be performed or observed pursuant to this Lease, and such
failure continues for thirty (30) days after written notice thereof is sent by Tenant to Landlord
informing Landlord of such failure, then Landlord shall be deemed to be in default under this
Lease; provided, however, that if the failure set forth in Tenant’s notice is such that it
requires more than thirty (30) days to correct, Landlord shall not be deemed to be in default
hereunder if Landlord: (i) promptly and diligently commences curing the failure within thirty (30)
days after written notice is sent by Tenant to Landlord informing Landlord of such failure; and
(ii) diligently prosecutes the cure to completion following the expiration of the original thirty
(30) day period set forth herein. Upon such default by Landlord, Tenant may, in addition to any
remedies available to it at law or in equity, perform the same for and on behalf of Landlord, the
cost of which performance, upon the proper payment thereof, together with all interest and
penalties necessarily paid in connection therewith and any and all other damages incurred by
Tenant as a result of any such default, shall be paid to Tenant by Landlord upon demand, with
interest thereon at the rate set forth in paragraph 7 of the Lease, from the date of each
expenditure.



          8.3. Waivers. A waiver by Landlord of a breach or default by Tenant under the terms
and conditions of this Lease shall not be construed to be a waiver of any subsequent breach or
default nor of any other term or condition of this Lease, and the failure of Landlord to assert
any breach or to declare a default by Tenant shall not be construed to constitute a waiver thereof
so long as such breach or default continues unremedied.



Exhibit A; page -6-
Lease Addendum









 





          8.4. No Accord or Satisfaction. No receipt of money by Landlord from Tenant after the
expiration or termination of this Lease or after the service of any notice or after the
commencement of any suit, or after final judgment for possession of the Premises shall reinstate,
continue or extend the term of this Lease or affect any such notice, demand or suit.


Article 9. Termination. Upon the termination of this Lease, by expiration or otherwise,
Tenant shall surrender the Premises to Landlord in as good condition and repair as when delivered
by Landlord, excepting ordinary wear and tear, condemnation, damage from any cause not required to
be repaired or replaced by Tenant and permitted Alterations. All Alterations and decorations made
to the Premises by and paid for by Tenant, in addition to all moveable furnishings, trade fixtures
and other equipment and personal property owned by Tenant, shall be removed from the Premises by
Tenant at Tenant’s sole cost and expense no later than the date of termination and Tenant shall
repair any and all damage caused by such removal. If the Premises are not surrendered upon the
scheduled termination of this Lease as set forth herein or within fifteen (15) days after earlier
termination as set forth herein, Tenant shall indemnify Landlord against all loss, liability and
expense (including reasonable attorneys’ fees) resulting from delay by Tenant in so surrendering
the Premises, including, without limitation, any claim made by any succeeding tenant founded on
such delay (but excluding Landlord’s lost profits so long as Tenant pays the holdover Rent called
for under paragraph 23 of the Lease). Tenant shall also surrender all keys to the Premises
and shall inform Landlord of combinations in any locks, safes and vaults, if any, in the Premises.
Notwithstanding the foregoing or anything to the contrary contained herein, if Tenant makes
alterations to any portion of the Premises in accordance with the provisions of Article 5
of this Addendum in order to convert such portion to biomedical manufacturing facilities, such
alterations regardless of the cost or scope shall not be required to be removed by Tenant at the
end of the Term, nor shall Tenant be required to reimburse Landlord for any costs of such removal.



Article 10. Quiet Enjoyment. Landlord covenants, warrants and represents to Tenant that it
has full right and power to execute and perform this Lease and to grant the estate demised herein,
and Landlord further covenants that Tenant shall peaceably and quietly have, hold and enjoy the
Premises and all rights, easements, appurtenances and privileges belonging or in any way
appertaining thereto, during the full Term, subject to all matters of record.



Article 11. Intentionally Omitted.



Article 12. Estoppel Certificates. Landlord and Tenant agree that at any time and from
time to time upon not less than ten (10) days prior request of the other, they shall execute,
acknowledge and deliver to the requesting party a statement in writing certifying (a) that this
Lease is unmodified and in full force and effect (or if there have been modifications, specifying
the same), (b) the dates to which the rent and other charges have been paid, (c) that, so far as
the party giving the estoppel knows, the other party is not in default under any provisions of
this Lease (or if the party giving the estoppel knows of any such default, specifying the same)
and (d) such other matters as the requesting party or its lender shall reasonably request. It is
intended that any such statement may be relied upon by any person proposing to acquire Landlord’s
or Tenant’s interest in this Lease or any prospective mortgagee of, or assignee of any mortgage
upon, such interest.





Exhibit A; page -7-
Lease Addendum









 







Article 13. Non-Liability of Landlord. Landlord shall not be liable to Tenant, and Tenant
hereby waives all claims against Landlord, for any injury or damage to any person or property in or
about the Premises resulting from the Premises, or any part thereof or any equipment thereof,
becoming out of repair; flooding of basements or other areas; damages caused by sprinkling devices,
air conditioning apparatus, snow, frost, water leakage, steam, excessive heat or cold, falling
plaster, broken glass, sewage, gas, odors or noise or the bursting or leaking of pipes or plumbing
fixtures; any act or neglect of other tenants or occupants or employees in the Premises; or any
other thing or circumstance whatsoever concerning the Premises, whether of a like nature or of a
wholly different nature unless caused by the willful misconduct or gross negligence of Landlord.
All property in or about the Premises belonging to Tenant, its agents, employees or invitees shall
be there at the risk of Tenant or other person only, and Landlord shall not be liable for damage
thereto or theft, misappropriation or loss thereof. If Landlord shall fail to perform any covenant
or condition of this Lease upon Landlord’s part to be performed and, as a consequence of such
default, Tenant shall recover a money judgment against Landlord, then such judgment shall be
satisfied only out of the proceeds of sale received upon execution of such judgment and levy
thereon against the right, title and interest of Landlord in the Premises and out of rents or other
income from such property receivable by Landlord and any insurance or condemnation proceeds that
are available for use by Landlord and Landlord shall not be personally liable for any deficiency.



Article 14. Transfer by Landlord. In the event of a sale or conveyance by Landlord of the
Premises, the same shall operate to release Landlord from any future liability upon any of the
covenants or conditions herein contained which accrue after the date of transfer, and in such
event Tenant agrees to look solely to the successor in interest of Landlord in and to this Lease,
provided, further, that the transferee expressly agrees in writing to assume the Landlord’s
obligations. This Lease shall not be affected by any such sale or conveyance, and Tenant agrees to
attorn to the purchaser or grantee, which shall be obligated on this Lease only so long as it is
the owner of Landlord’s interest in and to this Lease. Landlord shall give Tenant written notice
of any such transfer.



Article 15. No Liens. Without in each instance the prior written consent of Landlord,
Tenant shall not directly or indirectly create or permit to be created or to remain, and will
immediately discharge, any lien, encumbrance, or charge on, or pledge of, the Premises, or any
part thereof, the interest of Tenant hereunder or therein, or the rent or other payments
hereunder, other than: (a) this Lease; (b) any assignment, pledge, lien, encumbrance, charge,
conditional sale, or title retention agreement affecting the Premises, resulting solely from (i)
any action by Landlord or (ii) any liability or obligation of Landlord which Tenant is not
obligated by this Lease to assume; (c) liens for Taxes not yet payable; (d) liens of mechanics,
materialmen, suppliers, or vendors, or rights thereto, incurred in the ordinary course of business
for sums which under the terms of the related contracts are not yet due, provided that such
reserve or other appropriate provision, if any, as may be required by generally accepted
accounting principles shall have been made therefor; or (e) liens created to finance Tenant’s
removable trade fixtures, equipment and all other personal property. In amplification and not in
limitation of the foregoing, Tenant shall not knowingly permit any portion of the Premises to be
used by any person or persons or by the public, as such, at any time or times during the term of
this Lease, in such manner as might tend to impair the title or interest of Landlord in the
Premises, or any portion thereof, or in such manner as might make possible a claim or claims




Exhibit A; page -8-
Lease Addendum









 







of adverse use, adverse possession, prescription, dedication, or other similar claims of, in, to,
or with respect to the Premises, or any part thereof.



Article 16. Net Lease. This Lease is intended to be and shall be an absolute “net, net,
net” lease, and the Rent and all other sums payable hereunder by Tenant (all of which shall be
deemed to be Additional Rent) shall be paid without notice or demand and without set-off,
counterclaim, abatement, suspension, deduction, or defense except as otherwise provided in this
Lease. As more particularly set forth herein, Tenant shall pay all Taxes, insurance premiums,
maintenance, repair and replacement costs and expenses, utility charges and expenses, and all other
costs and expenses, of whatever nature, relating in any way to the Premises and/or the operation
thereof during the term of this Lease except as otherwise provided in this Lease. In addition, this
Lease shall continue in full force and effect and the obligations of Tenant hereunder shall not be
released, discharged, diminished, or otherwise affected by reason of any damage to or destruction
of the Premises, or any part or parts thereof any partial taking; any restriction on or prevention
of or interference with any use of the Premises, or any part or parts thereof, except as otherwise
provided in this Lease. It is expressly understood and agreed that, except as specifically stated
herein to the contrary, Landlord shall have no responsibility or obligation, whatsoever, with
respect to the Premises or the condition or use thereof during the term of this Lease and shall be
absolutely, without limitation, exculpated from any and all such responsibilities and/or
obligations, all such responsibilities and obligations being those of Tenant.



Article 17. Environmental Covenants. Tenant shall not use the Premises for the production,
sale or storage of any toxic or hazardous chemicals, wastes, materials or substances, or any
pollutants or contaminants, as those terms are defined in any applicable federal, state, local or
other governmental law, statute, ordinance, code, rule or regulation (“Hazardous Substances”),
shall not use any Hazardous Substance in the Premises, and shall not permit any Hazardous
Substance to be disposed of from, in or on the Premises, unless said Hazardous Substances are of
the type normally used in the ordinary course of operating and maintaining Tenant’s office and
laboratory facilities, and are stored, used and disposed of in strict accordance with all such
laws, statutes, ordinances, codes, rules and regulations which are applicable to the Premises
(“Environmental Regulations”). Tenant shall not permit any Hazardous Substance to be emitted,
discharged, released, spilled or deposited from, in or on the Premises other than in the ordinary
course of operating and maintaining Tenant’s office and laboratory facilities as may be permitted
by law or applicable permit held by Tenant. Tenant shall obtain and maintain all licenses and
permits, and shall maintain all material safety data sheets, with respect to such Hazardous
Substances, which are required by any Environmental Regulation. Landlord shall have the right to
enter the Premises to inspect the same for compliance with the provisions of this Article
17; provided that: (i) entrance to the Premises shall not be denied to Tenant; (ii) the
business of Tenant shall not be interfered with unreasonably; and (iii) Landlord shall comply with
Tenant’s safety and other reasonable rules governing activities within the Premises. Tenant agrees
to indemnify Landlord against, and to hold Landlord harmless from, any and all claims, demands,
judgments, fines, penalties, costs, damages and expenses resulting from any violation by Tenant of
this Article 17 or of any Environmental Regulation, including court costs and attorneys,
fees in any suit, action administrative proceeding or negotiations resulting therefrom, and
including costs of remediation, clean-up and detoxification of the Premises and the environment
unless caused by the willful misconduct or gross negligence of Landlord. Tenant’s obligations and




Exhibit A; page -9-
Lease Addendum









 







liabilities under this Article 17 shall survive the termination of this Lease.



Article 18. Modifications. Tenant agrees to execute any reasonable modification of this
Lease which may be required by a lender as a condition to making a first mortgage loan on the
Premises; provided that no such modification shall alter the rent or term provided herein or reduce
the full economic value hereof or involve cost to Tenant.



Article 19. Intentionally Omitted.



Article 20. Force Majeure. In the event that Landlord or Tenant shall be delayed or
hindered in or prevented from the performance of any act required hereunder by reason of a Force
Majeure event, then performance of such act shall be excused for the period of the delay and the
period for the performance of any such act shall be extended for a period equivalent to the period
of such delay; provided that nothing contained in this Section 35 shall excuse, delay or otherwise
apply to the Tenant’s obligation to pay rent or any other monetary obligation hereunder. For
purposes hereof, a “Force Majeure” event shall mean delays or hindrances caused by (i) acts of
God; (ii) strikes, labor disputes, labor shortages (materially worse than the current labor supply
conditions in effect in October 2006) or material shortages outside of the party’s control; (iii)
blackouts; (iv) acts of public enemy; (v) orders of any kind of the government of the United
States or of the State of Maryland or any department, agency, political subdivision or official of
either of them, or any civil or military authority; (vi) riots; (vii) epidemics disabling the
labor force; (viii) landslides; (ix) earthquakes affecting the Premises; (x) fires; (xi)
hurricanes and/or tornadoes; (xii) adverse weather conditions (i.e., the number of days in excess
of the normal weather [rain or snow days] as defined for a thirty (30) day period by the National
Weather Bureau for the Rockville, Maryland metropolitan area); (xiii) floods; (xiv) partial or
entire failure of public utilities affecting the Premises; or (xiv) any other similar cause or
event not reasonably within the control of party and not resulting from that party’s acts or
omissions. Landlord and Tenant shall give notice to each other of the occurrence of any event of
Force Majeure that may give rise to a claim for an extension of time to perform hereunder as soon
as reasonably possible after the discovery by such party of such Force Majeure event. The party
claiming the benefit of any such Force Majeure event shall thereafter use all reasonable diligence
in attempting to overcome or lessen the impact of such Force Majeure event and shall keep the
other reasonably informed of their progress in mitigating the effects of any such Force Majeure
event.



Article 21. Miscellaneous.




          21.1. Costs and Attorney Fees. Upon any dispute between Landlord and Tenant under
this Lease, the prevailing party shall be entitled to recover from the non-prevailing party
reasonable attorneys’ fees, taxable costs and expenses incurred in contesting such dispute.



          21.2. Independent Covenants. The covenant to pay rent or any additional charge is
hereby declared to be an independent covenant on the part of Tenant to be kept and performed, and
no such Rent or charge shall be subject to any offset or deduction whatsoever.



          21.3. Emergencies. In case of emergency, if Tenant shall not be present to permit
entry, Landlord or its representatives may enter the same forcibly without rendering Landlord or
its



Exhibit A; page -10-
Lease Addendum









 







representatives liable therefor or affecting Tenant’s obligation under this Lease.



          21.4. No Agency. Nothing contained in this Lease shall be taken or construed to create any
agency between Landlord and Tenant or to authorize the Tenant to do any act or thing or to make
any contract so as to encumber in any manner the title of the Landlord to the Premises or to
create any claim or lien upon the interest of the Landlord in the Premises.



          21.5. No Recording of Lease. Landlord and Tenant shall not record this Lease or any
memorandum thereof, and Tenant shall indemnify Landlord against and hold Landlord harmless from
any and all fees and/or taxes imposed by any governmental entity for or on account of the
recording of this Lease or any memorandum thereof.



          21.6. Financial Statements. Tenant shall, within ninety (90) days after the end of
each fiscal year of Tenant, and within thirty (30) days after receipt of written request from
Landlord, provide to Landlord, for the benefit of Landlord, Landlord’s mortgagee and any
prospective mortgagee or purchaser of the Premises audited financial statements of Tenant,
including: (i) a balance sheet and profit and loss statement of Tenant for Tenant’s most recent
fiscal year, and (ii) a detailed operating statement of the Premises for the most recent calendar
year. Notwithstanding the foregoing, so long as the Tenant is a publicly traded corporation, Tenant
shall only be required to provide Landlord with (a) a detailed operating statement of the Premises
for the most recent calendar year, and (b) such financial information on Tenant as is made
