ARTICLE
2 - DEMISED PREMISES AND PERSONAL PROPERTY

 

2.1       Lessor,
for and in consideration of the Rent to be paid and the other covenants and agreements hereinafter reserved, mentioned and contained
to be kept and performed by Lessee and its successors and assigns, does hereby lease unto Lessee the Leased Property for the Term, for
use and operation therein and thereon of Medicaid and Medicare certified skilled and intermediate care nursing home facilities, in full
compliance with all the rules and regulations and minimum standards applicable thereto, as prescribed by the State of Nebraska and such
other governmental authorities having jurisdiction thereof, each Facility Property having no less than the number of licensed Medicare
and Medicaid certified beds as set forth in the first recital of this Lease for such Facilities, and for any other purpose authorized
by Lessor in writing and for no other purpose.

 

2.2       This
Lease constitutes one indivisible lease of the entire Leased Property. The Leased Property constitutes one economic unit and the Base
Rent and all other provisions have been negotiated and agreed to based on a lease of all of the Leased Property as a single, composite,
inseparable transaction. This Lease would not have been made on these terms if it was not a single indivisible lease. Except as expressly
provided herein for specific, isolated purposes (and then only to the extent expressly otherwise stated), all provisions of this Lease
shall apply equally and uniformly to all the Leased Property as one unit and any Event of Default under this Lease is an Event of Default
as to the entire Leased Property. The parties intend that the provisions of this Lease shall at all times be construed, interpreted and
applied so as to carry out their mutual objective to create a single indivisible lease of all the Leased Property, and in particular
but without limitation, that for purposes of any assumption, rejection or assignment of this Lease under the Bankruptcy Code, this is
one indivisible and nonseverable lease and executory contract dealing with one legal and economic unit which must be assumed, rejected
or assigned as a whole with respect to all (and only all) the Leased Property covered hereby. The parties agree that the existence of
more than one Lessor under this Lease does not affect the indivisible, nonseverable nature of this Lease. The parties may amend this
Lease from time to time to include one or more additional Facilities as part of the Leased Property and such future addition to the Leased
Property shall not in any way change the indivisible and nonseverable nature of this Lease and all of the foregoing provisions shall
continue to apply in full force.

 

ARTICLE
3 - TERM OF LEASE

 

3.1       Except
as expressly provided below, the term of this Lease shall be for a period of twelve (12) years and nineteen (19) days commencing on the
date hereof (the “Commencement Date”), and shall expire on May 31, 2027 (the “Initial Term”), unless terminated
earlier as provided for herein.

 

    	4

     

    

 

3.2       Lessee
shall have and is hereby granted the right and option to extend the Initial Term of this Lease for an extended term (the “First
Extended Term”) of ten (10) Lease Years upon and subject to all the terms, provisions and conditions hereof, except that Base Rent,
as hereinafter defined, payable with respect to each Lease Year of the First Extended Term shall be the amount set forth in Section 4.1.
The first Lease Year of the First Extended Term shall commence upon the day next following the expiration of the Initial Term.

 

The
option granted pursuant to this Section 3.2 may be exercised only if Lessee is not in default under this Lease at the time of exercise
and at the time of expiration of the Initial Term, and, further, only if there is not at either time an event or occurrence which with
the passage of time or giving of notice, or both, would constitute a default hereunder, and said option shall be exercised by Lessee
giving to Lessor written notice of Lessee’s election so to do not less than twenty-four (24) full calendar months prior to the
date of expiration of the Initial Term.

 

3.3       Lessee
shall have and is hereby granted the right and option to extend the First Extended Term of this Lease for an extended term (the “Second
Extended Term”) of ten (10) Lease Years upon and subject to all the terms, provisions and conditions hereof, except that Base Rent,
as hereinafter defined, payable with respect to each Lease Year of the Second Extended Term shall be the amount set forth in Section
4.1. The first Lease Year of the Second Extended Term shall commence upon the day next following the expiration of the First Extended
Term.

 

The
options granted pursuant to Sections 3.2 and 3.3 may be exercised only if Lessee is not in default under this Lease at the time
of exercise and at the time of expiration of the First Extended Term, and, further, only if there is not at either time an event or occurrence
which with the passage of time or giving of notice, or both, would constitute a default hereunder, and said option shall be exercised
by Lessee giving to Lessor written notice of Lessee’s election so to do not less than twenty-four (24) full calendar months prior
to the date of expiration of the First Extended Term.

 

The
Initial Term, as it may be extended by the First Extended Term and, as it may be extended by the Second Extended Term, is hereinafter
collectively known as the “Term”.

 

3.4       It
is anticipated that the closing of the purchase of the Crete Plus Five Leased Property by Lessor from Seller will occur on or before
July 1, 2015. Lessee hereby agrees that the obligations of this Lease with respect to the Crete Plus Five Leased Property, the obligations
of Lessor and the rights of Lessee to lease the Crete Plus Five Leased Property pursuant to this Lease shall commence concurrently with
the applicable Lessor’s acquisition of the Crete Plus Five Leased Property, but each of Lessor and Lessee acknowledge and agree
that, except as otherwise expressly provided in this Section 3.4, such obligations are subject to and conditioned upon the purchase of
the Crete Plus Five Leased Property by the applicable Lessor. In no event shall the provisions of this Lease be effective as to the Crete
Plus Five Leased Property prior to the time the applicable Lessor closes on the purchase of the Crete Plus Five Leased Property; provided,
however, in the event that the applicable Lessor terminates the Purchase Agreement based on the condition of the Crete Plus Five Leased
Property or the results of its due diligence investigations or otherwise, Lessee shall pay any Closing Costs incurred by Lessor not recovered
by Lessor from the seller under the Purchase Agreement.

ARTICLE
4 - BASE RENT

 

4.1       Lessee
shall pay to Lessor a monthly rental (“Base Rent”) for the Demised Premises and the Personal Property over and above all
other and additional payments to be made by Lessee as provided in this Lease, in the amount set forth on Exhibit C attached hereto and
made a part hereof. The payment of monthly Base Rent and Additional Rent (together with all tax and insurance deposits required pursuant
to Section 7.1) shall be due and payable in advance on the first day of each calendar month during the Term. Unless otherwise notified
in writing, all payments of Rent shall be sent by wire directly to such account as Lessor has previously or may in the future designate
in writing from time to time. Base Rent and Additional Rent shall be referred to herein as “Rent.” The parties hereto acknowledge
and agree that the Rent payable for May 2015 and prior periods are subject to payment as provided under the terms of Lease 1, Lease 2
and Lease 3, as applicable, and that the Base Rent schedule attached hereto as Exhibit C will commence on June 1, 2016.

 

4.2       The
parties agree that the Base Rent that will be attributable collectively to the Crete Plus Five Leased Property is based on the parties’
assumption that Lessor shall purchase same pursuant to the Purchase Agreement for an aggregate purchase price of Fifteen Million and
00/100 Dollars ($15,000,000.00) plus any Closing Costs incurred by the applicable Lessor in connection therewith (collectively, the “Purchase
Price”). The parties agree that the Base Rent due and payable under this Lease shall be increased immediately upon the closing
of the acquisition of the Crete Plus Five Leased Property in an initial annualized amount equal to Nine Percent (9.0%) of the Purchase
Price, such amount to increase at the commencement of each Lease Year by an amount equal to the same percentage that Base Rent payable
hereunder would have increased had the Crete Plus Five Lease Property not been acquired. Immediately prior to the closing of the Crete
Plus Five Leased Property purchase and sale, Lessor shall deliver to Lessee a written statement setting forth the amount of the Purchase
Price, including the amount of Closing Costs, and the amount of the adjusted Base Rent for the duration of the first Lease Year, which
statement shall, without further action by Lessee, establish the Base Rent until the first adjustment date. In the event that the final
total amount of the Purchase Price cannot be determined as of the date the Crete Plus Five Leased Property is acquired and subject to
this Lease, the Base Rent shall be adjusted as of the date such final total Purchase Price is finally determined by Lessor, and Lessee
shall immediately pay Lessor an amount equal to the difference between the Base Rent as of the date the Crete Plus Five Leased Property
is acquired and subject to this Lease and the adjusted Base Rent for all periods preceding the date in which the final total Purchase
Price is finally determined. In the event the date the Crete Plus Five Leased Property is acquired and subject to this Lease shall
be other than the first day of the month, Lessee shall pay to Lessor a pro rata portion of the Base Rent and Additional Rent for the
month and a pro rata portion of all tax, insurance and other deposits provided for in this Lease.

 

4.3       Base
Rent during the first Lease Year of the First Extended Term, if exercised, and the first Lease Year of the Second Extended Term,
if exercised, shall be equal to nine percent (9%) of the Appraised FMV (as hereinafter defined), which shall be determined after Lessee
exercises each of its respective options. As used herein, the term “Appraised FMV” means the appraised fair market value
of the Leased Property, as determined by a Qualified Appraiser (as defined below), based on the assumption that the Leased Property will
continue to be operated as a skilled nursing facility, assisted living facility or independent living facility, as applicable. The term
“Qualified Appraiser” means an appraiser certified as an MAI appraiser or with equivalent certification, and mutually acceptable
to Lessor and Lessee. In the event that Lessor and Lessee cannot reach agreement as to the Qualified Appraiser, Lessor and Lessee shall
each choose a Qualified Appraiser who shall, within ten (10) business days of such selection meet and select a third Qualified Appraiser
to determine the Apprised FMV; provided, however, Base Rent during the first Lease Year of the First Extended
Term and the first Lease Year of the Second Extended Term shall not: (a) be less than the one hundred two percent (102%) of the Base
Rent payable in the immediately preceding Lease Year; nor (b) increase by more than fifteen percent (15%) of the Base Rent payable during
the immediately preceding Lease Year. The cost and expenses for each Qualified Appraiser shall be paid by Lessee. On the first
anniversary of the First Extended Term, and on each anniversary thereafter during the First Extended Term, the Base Rent shall increase
by two percent (2.0%) over the Base Rent in effect for the prior Lease Year. On the first anniversary of the Second Extended Term, and
on each anniversary thereafter during the Second Extended Term, the Base Rent shall increase by two percent (2.0%) over the Base Rent
in effect for the prior Lease Year.

 

    	6

     

    

 

4.4       This
Lease is and shall be deemed and construed to be a “pure net” or “triple- net” lease and the Rent specified herein
shall be net to Lessor in each year during the Term of this Lease. Lessee shall pay all costs, expenses and obligations of every kind
whatsoever relating to the Demised Premises which may arise or become due during the Term, except for Lessor’s income taxes, franchise
taxes and any principal and interest payments relating to any Mortgage/Underlying Lease (collectively, “Additional Rent”).
Lessee does hereby indemnify Lessor against any and all such costs, expenses and obligations. Lessor shall not be required to provide
any service or do any act or thing with respect to the Leased Property or any part thereof, including the buildings and improvements
thereon and the appurtenances thereto.

 

4.5       Lessee
recognizes and acknowledges that Lessor and/or certain beneficial owners of Lessor may from time to time qualify as real estate investment
trusts pursuant to Sections 856 et seq. of the Internal Revenue Code of 1986, as amended, and that avoiding (a) the loss of such status,
(b) the receipt of any income derived under any provision of this Lease that does not constitute “rents from real property”
(in the case of real estate investment trusts), and (c) the imposition of income, penalty or similar taxes (each an “Adverse Event”)
is of material concern to Lessor and such beneficial owners. In the event that this Lease or any document contemplated hereby could,
in the opinion of counsel to Lessor, result in or cause an Adverse Event, Lessee agrees to cooperate with Lessor in negotiating an amendment
or modification thereof and shall at the request of Lessor execute and deliver such documents reasonably required to effect such amendment
or modification. Any amendment or modification shall be structured so that the economic results to Lessor and Lessee shall be substantially
similar to those set forth in this Lease without regard to such amendment or modification. Without limiting any of Lessor’s other
rights pursuant to this provision, Lessor may waive the receipt of any amount payable to Lessor hereunder and such waiver shall constitute
an amendment or modification of this Lease with respect to such payment.

 

ARTICLE
5 - LATE CHARGES

 

5.1
If payment of any sums required to be paid or deposited by Lessee to Lessor under this Lease, and payments made by Lessor under any provision
hereof for which Lessor is entitled to reimbursement by Lessee, shall become overdue beyond three (3) days after the date on which they
are due and payable as in this Lease provided, a late charge of five percent (5%) per month on the sums so overdue shall become immediately
due and payable to Lessor and said late charges shall be payable on the first day of the month next succeeding the month during which
such late charges become payable. If non-payment of any late charges shall occur, Lessor shall have, in addition to all other rights
and remedies, all the rights and remedies provided for herein and by law in the case of non-payment of Rent. No failure by Lessor to
insist upon the strict performance by Lessee of Lessee’s obligations to pay late charges shall constitute a waiver by Lessor of
its rights to enforce the provisions of this Article in any instance thereafter occurring.

ARTICLE
6 - PAYMENT OF TAXES AND ASSESSMENTS

6.2       Any
Taxes and Assessments relating to a fiscal period of any authority, a part of which is included within the Term and a part of which is
included in a period of time before or after the Term, shall be adjusted pro rata between Lessor and Lessee and each party shall be responsible
for its pro rata share of any such Taxes and Assessments.

 

6.3       Nothing
herein contained shall require Lessee to pay income taxes assessed against Lessor, or capital levy, franchise, estate, succession or
inheritance taxes of Lessor.

 

6.4       If
any income, profits or revenue tax shall be levied, assessed or imposed upon the income, profits or revenue arising from Rent payable
hereunder, partially or totally in lieu of or as a substitute for real estate or personal property taxes imposed upon the Demised Premises
or Personal Property, or otherwise, then Lessee shall be responsible for the payment of such tax.

 

ARTICLE
7 - DEPOSITS FOR TAXES AND ASSESSMENTS AND INSURANCE

 

7.1       Lessee shall be required to make deposits for Taxes and Assessments and, upon notice to Lessee, insurance premiums, and will make monthly
deposits with Lessor, of an amount equal to one-twelfth (1/12) of the Taxes and Assessments or such greater amount as may be required

as Additional Rent, shall not bear interest and shall be held, at Lessor’s option, by Lessor and/or Mortgagee/Underlying Lessor
to pay the Taxes and Assessments and insurance premiums as they become due and payable. If the total of the monthly payments as made

(according to any plans or specifications which may be adopted therefor) in excess of the amount received from any such insurance policies
has been expended or provided by Lessee for such repairing, rebuilding, restoring or replacing, and that the amount received from such
insurance policies is sufficient to complete such work. In the event there is any amount required in excess of the amount received from
such insurance policies, Lessee shall deposit such excess funds with Lessor so that the total amount available will be sufficient to
complete such repairing, rebuilding, restoring or replacing in accordance with the provisions of any Mortgage/Underlying Lease and any
plans and specifications submitted in connection therewith, free from any liens or encumbrances of any kind whatsoever and the funds
held by Lessor shall be disbursed only upon presentment of architect’s or general contractor’s certificates, waivers of lien,
contractor’s sworn statements, and other evidence of cost and payments as may be reasonably required by Lessor or any Mortgagee/Underlying

Premises as Medicaid and Medicare certified skilled and intermediate care nursing home facilities with each Facility having no less than
the number of licensed Medicare and Medicaid certified beds as set forth in the first recital of this Lease. Any items of Personal Property
that are uneconomical to repair shall be replaced by new items of first- class quality and all replacement items shall become part of

of such items. In performing such repairs, Lessee shall comply in all respects with Section 14.1 of this Lease, and shall deliver to

by fire or other casualty (any such event being called a “Casualty”), Lessee shall promptly and with all due diligence,
but in any event on or before one year after the date of such Casualty, replace, repair and restore the same as nearly as possible
to the condition it was in immediately prior to such Casualty, in accordance with all of the terms, covenants and conditions and
other applicable requirements of this Lease and any Mortgage/Underlying Lease in the event of such Casualty, whether or not the
insurance proceeds or other compensation are sufficient to pay the cost of such restoration and repair. The Demised Premises and the
Personal Property shall be so replaced, repaired and restored as to be of at least equal value and substantially the same character
as prior to such Casualty. Lessee shall submit to Lessor for Lessor’s prior written approval plans and specifications for any
such restoring, replacing or repairing, and Lessee shall immediately select an independent architect approved by Lessor and any
Mortgagee/Underlying Lessor, who shall be in charge of such repairing, restoring and replacing. Without limitation of Lessor’s
rights hereunder, there shall be the following additional conditions precedent to any disbursement of insurance proceeds: (i) at the
time of each and every disbursement there shall exist no Event of Default under this Lease nor any event which with the passage of
time or the giving of notice or both would constitute an Event of Default hereunder and (ii) Lessor and Mortgagee/Underlying Lessor,
if applicable, shall have approved all plans and specifications for any proposed repair or restoration. Lessee covenants that it
will give to Lessor prompt written notice of any Casualty affecting the Leased Property. Provided that Lessee is not in default
under this Lease, Lessee shall have the right, at any time and from time to time, to remove and dispose of any Personal Property
which may have become obsolete or unfit for use, or which is no longer useful in the operation of the Demised Premises, provided
further that Lessee promptly replaces any such Personal Property so removed or disposed of with other personal property free of any
security interest, lien or encumbrance. Said replacement Personal Property shall be of the same character and at least equal
usefulness and quality to such Personal Property so removed or disposed of and such replacement Personal Property shall
automatically become the property of and shall belong to Lessor, and Lessee shall execute such bills of sale or other documents
reasonably requested by Lessor to vest the ownership of such Personal Property in Lessor. Notwithstanding anything to the contrary
in this Lease, there shall be no abatement or other adjustment of Rent as a result of such Casualty.

any such lien, encumbrance or charge is created upon the Demised Premises or any part thereof, then in addition to any other right
or remedy, Lessor may, upon ten (10) days notice, but shall not be obligated to, discharge the same either by paying the
amount claimed to be due or by processing the discharge of such lien by deposit or by bonding proceedings. Any amount so paid by
Lessor and all costs and expenses incurred by Lessor in connection therewith, together with interest thereon at the Default Rate,
shall constitute Additional Rent payable by Lessee under this Lease and shall be paid by Lessee to Lessor on demand. Except as
herein provided, nothing contained herein shall in any way empower Lessee to do or suffer any act which can, may or shall cloud or

16 - CONDEMNATION

 

16.1     In
the event any entire Facility Property shall be taken or sold under the threat of such taking for any public use by act of any public
authority (hereinafter referred to as a “Taking”), then this Lease shall terminate with respect to such Facility Property
as of the date of such Taking. Upon such termination, the Base Rent shall be reduced by an amount equal to ratio of the actual net award
for such Taking received by Lessor to the amount paid by Lessor to acquire the Demised Premises, unless there is only one Facility Property
subject to this Lease in which case this Lease will terminate. The termination of this Lease as to any Facility Property due to a Taking
is the result of circumstances beyond the control of Lessor and Lessee and the parties hereto affirm that, except for such specific isolated
situation, this Lease is intended to be a single indivisible lease. All damages awarded for such Taking under the power of eminent domain
shall be the property of Lessor, whether such damages shall be awarded as compensation for diminution in value of the leasehold or the
fee of the Facility Property. Lessee shall be entitled, if provided by law, to pursue and receive a separate award from the condemning
authority for loss of Lessee’s interest in the Facility Property, but only if the award to which Lessor would have otherwise been
entitled had Lessee not received or participated in such award, is not diminished thereby, directly or indirectly, and, further, in no
event shall Lessee be entitled to an apportionment of any condemnation award or settlement which Lessor would have been entitled to receive
with respect to such Taking but for the above provision and Lessee hereby assigns to Lessor any and all right, title and interest Lessee
may have in any and all such awards or settlements.

 

16.2     In
the event of a partial Taking of a Facility Property the result of which shall be a reduction in the number of licensed beds at the
Facility Property by fifty percent (50%) or more of the Facility Property licensed capacity existing prior to such Taking, Lessor
shall have the option (i)       to terminate this Lease with respect to such Facility Property as
of the date of such Taking in which case the Base Rent shall be adjusted as provided in Section 16.1 of this Lease or (ii) Lessor
shall hold in trust that portion, if any, of such award, settlement or compromise which shall be allocable to consequential damage
to buildings and improvements not taken, and Lessor shall pay out such portion to Lessee to reimburse Lessee for the cost of
restoring the Facility Property as a complete structural unit, as such restoration work progresses in accordance with the procedure
for making insurance proceeds available for restoration, repair or rebuilding as set forth in Articles 9 and 11. Lessor shall be
entitled to retain any excess portion of such award, settlement or compromise, Lessee shall be entitled, if provided by law, to
pursue and receive a separate award from the condemning authority for loss of Lessee’s interest in the Facility Property, but
only if the award to which Lessor would have otherwise been entitled had Lessee not received or participated in such award, is not
diminished thereby, directly or indirectly, and, further, in no event shall Lessee be entitled to an apportionment of any
condemnation award or settlement which Lessor would have been entitled to receive with respect to such Taking but for the above
provision and Lessee hereby assigns to Lessor any and all right, title and interest Lessee may have in any and all such awards or
settlements. In the event of a partial condemnation, the monthly Base Rent payable under Section 4.1 hereof shall not be
reduced.

survey or physical inspection thereof might show, and to all zoning regulations, restrictions, rules and ordinances, building restrictions
and other laws and regulations now in effect or hereafter adopted by any governmental authority having jurisdiction thereover. Lessee

Lessor and that Lessee has the leasehold rights as set forth in the terms and conditions of this Lease.

 

17.2     As
a material inducement to Lessor in the making of and entry into this Lease, Lessee hereby expressly agrees as follows:

way of limitation); the soil and geology thereof, the waters thereof and thereunder; the drainage thereof; the manner of construction
and the condition and state of repair and lack of repair of all improvements of every nature; the nature, provisions and effect of all

adverse possession, profit, servitude, lease, tenancy, lien, encumbrance, license, contract, reservation, condition, right of re-entry,
possibility of reverter, sufferance or otherwise. Lessor makes no representation as to, and has no duty to be informed with respect to,
any of the matters set forth in the preceding sentence. Lessee hereby accepts the Leased Property as suitable and adequate in all respects
for the conduct of the business and the uses of the Leased Property as contemplated under the provisions of this Lease.

 

(2)       Lessee
expressly covenants and agrees that it hereby takes this Lease and the leasehold estate hereby established upon and subject to Lessor’s
title as it was acquired from its seller, including all rights, rights of way, easements, profits, servitudes, reservations, restrictions,
conditions, exceptions, reversions, possibilities of reverter, liens, encumbrances, occupancies, tenancies, licenses, clouds, claims
and defects, known and unknown and whether of record or not.

 

(3)       Lessee
hereby expressly waives any and all rights which it might have against Lessor by reason of any of the foregoing, including (but not limited
to) the requirements of any inspection or examination by Lessee of the Leased Property.

 

17.3     Except
as otherwise specifically provided in this Lease, this Lease shall continue in full force and effect, and the obligations of Lessee hereunder
shall not be released, discharged or otherwise affected, by reason of: (i) any damage to or destruction of the Leased Property or any
part thereof or the taking of the Leased Property or any part thereof by condemnation, requisition or otherwise for any reason, (ii)
any restriction or prevention of or interference with any use of the Leased Property or any part thereof, including any restriction or
interference with or circumstance which prevents the use of the Leased Property as contemplated by Section 8.1, (iii) any frustration
of Lessee’s purposes hereunder, (iv) any claim which Lessee has or might have against Lessor, or (v) any other occurrence whatsoever,
whether similar or dissimilar to the foregoing.

17.4     Without
limiting the generality of Subsection 17.3 above, Lessee’s obligation to pay Base Rent and Additional Rent to Lessor under
this Lease is a covenant independent of all other covenants made by Lessor and Lessee hereunder and Lessee shall pay all Base Rent and
Additional Rent to Lessor without any setoff or deduction.

assign this Lease or in any manner whatsoever sublet, assign, sell, pledge, encumber or transfer all or any part of the Leased Property
or any interest in the Leased Property or enter into any management or other similar agreement pursuant to which a party shall undertake
responsibility for the management and operation of the Leased Property or any portion thereof. Further, Lessee shall not cause or permit
any sale, transfer, pledge, assignment or encumbrance of any direct or indirect ownership interest or voting rights in Lessee whether
voluntarily, involuntarily, by operation of law or otherwise, and any such act or occurrence shall be deemed to be an assignment of this
Lease, and shall require Lessor’s prior written consent which may be withheld in Lessor’s sole discretion. Any violation
or breach or attempted violation or breach of the provisions of this Article by Lessee, or any acts inconsistent herewith shall vest
no right, title or interest herein or hereunder or in the Leased Property, in any such transferee or assignee, and any such violation,
breach or attempted violation or breach shall constitute an Event of Default hereunder permitting Lessor to terminate this Lease or to
exercise any of its other remedies in accordance with the provisions of Article 21 herein without any right of Lessee to cure
the same. Lessor’s consent to any of the foregoing shall not release Lessee from, or otherwise affect, Lessee’s obligations
and liabilities under this Lease. Notwithstanding the foregoing, Lessor hereby consents to a sublease the Facilities to Sublessees pursuant
to the subleases listed on Schedule 18.1 attached hereto and made a part hereof; provided however, Lessee shall not amend, modify,
terminate or assign any such subleases nor cause or permit any sale, transfer, pledge, assignment or encumbrance of any direct or indirect
ownership interest or voting rights in any such Sublessee without the prior written consent of Lessor, which may be withheld in Lessor’s
sole and absolute discretion. The approval by Lessor of such sublease shall not relieve Lessee’s compliance with the terms and
provisions of this Lease nor shall said approval be considered a waiver of Lessee’s obligation to obtain Lessor’s prior written
consent to any further assignment or sublease of the Leased Property as required by this Article. Notwithstanding the foregoing, Lessor’s
consent shall not be unreasonably withheld to any transfer of the ownership interests in Lessee to employees of Lessee, provided, however,
that the majority of ownership interests in Lessee shall be retained by Rich Mason and Shayne Bench such that the Lessee is under the
sole and exclusive control of Rich Mason and Shayne Bench.

21 - LESSOR’S REMEDIES UPON DEFAULT

 

21.1     In
the event of any Event of Default on the part of Lessee, Lessor may, if it so elects, with or without any demand whatsoever upon Lessee,
forthwith either to (i) terminate this Lease and Lessee’s right to possession of the Demised Premises; or (ii) terminate Lessee’s
right to possession of the Demised Premises without terminating this Lease. Upon any such termination of this Lease, or upon any such
termination of Lessee’s right to possession without termination of this Lease, Lessee shall vacate the Demised Premises immediately,
and shall quietly and peaceably deliver possession thereof to Lessor, and Lessee hereby grants to Lessor full and free license to enter
into and upon the Demised Premises in such event with or without process of law and to repossess the Demised Premises and the related
Personal Property as Lessor’s former estate. In the event of any such termination of this Lease, Lessor shall again have possession
and enjoyment of the Demised Premises subject to such termination and the related Personal Property to the extent and as if this Lease
had not been made, and thereupon the lease of the Demised Premises and everything herein contained on the part of Lessee to be done and
performed in connection therewith shall cease and terminate, all, however, without prejudice to and without relinquishing the rights
of Lessor to Rent (which, upon such termination of this Lease and entry of Lessor upon the Demised Premises or any portion thereof, shall,
in any event, be the right to receive Rent due up to the time of such entry) or any other right given to Lessor hereunder or by operation
of law.

 

21.2     In
the event Lessor elects either to terminate this Lease or to terminate Lessee’s right to possession of the Demised Premises upon
the occurrence of an Event of Default, then all licenses, certifications, permits and authorizations issued by any governmental agency,
body or authority in connection with or relating to the Facilities shall be deemed as being assigned to Lessor. Lessor shall also have
the right to continue to utilize the telephone numbers and names used by Lessee in connection with the operation of the nursing homes
located on the Facilities. This Lease shall be deemed and construed as an assignment for purposes of vesting in Lessor all right, title
and interest in and to (i) all licenses, certifications, permits and authorizations obtained in connection with the Facilities and (ii)
the names and telephone numbers used in connection with the Facilities. Lessee hereby agrees to take such other action and execute such
other documents as may be necessary in order to vest in Lessor all right, title and interest to the items specified herein.

 

21.3     If
Lessee abandons the Demised Premises or otherwise entitles Lessor so to elect, and Lessor elects, to terminate Lessee’s right to
possession only of the Demised Premises without terminating this Lease, Lessor may, at its option, enter into the Demised Premises, remove
Lessee’s signs and other evidence of tenancy and take and hold possession thereof as provided in the foregoing Section 21.1 of
this Article, without such entry and possession terminating this Lease or releasing Lessee, in whole or in part, from Lessee’s
obligation to pay the Rent hereunder for the full remaining Term, and in any such case, Lessee shall pay to Lessor a sum equal to the
entire amount of the Rent reserved hereunder and required to be paid by Lessee up to the time of such termination of the right of possession
plus any other sums then due hereunder. Upon and after entry into possession without termination of this Lease, Lessor may attempt to
relet the Demised Premises for the account of Lessee for such Rent, or shall operate the Facilities for such time and upon such terms
as Lessor in its sole discretion shall determine. In any such case, Lessor may make repairs, alterations and additions in or to the Demised
Premises, and redecorate the same to the extent deemed by Lessor desirable, and Lessee shall, upon demand, pay the cost thereof, together
with Lessor’s expenses of reletting. If the consideration collected by Lessor upon any such reletting is not sufficient to pay
monthly the full amount of Rent reserved in this Lease, together with the reasonable costs of repairs, alterations, additions, redecorating
and Lessor’s expenses, Lessee shall pay to Lessor the amount of each monthly deficiency upon demand.

 

21.4     Upon
any such termination of this Lease or at any time after such termination of Lessee’s right to possession, Lessor may recover from
Lessee and Lessee shall pay to Lessor as liquidated and final damages, whether or not Lessor shall have collected any current monthly
deficiencies under the foregoing paragraph, and in lieu of such current deficiencies after the date of demand for such final damages,
the amount thereof found to be due by a court of competent jurisdiction, which amount thus found may be equal to:

 

    	20

     

    

 

(1)       the
remainder, if any, of Rent charges due from Lessee for the period up to and including the date of the termination of this Lease or Lessee’s
right to possession; and

 

(2)       the
amount of any current monthly deficiencies accruing and unpaid by Lessee up to and including the date of Lessor’s demand for final
damages hereunder; and

 

(3)       the
Rent reserved for what would have been the remainder of the Term with respect to the Demised Premises together with charges to be paid
by Lessee under this Lease.

 

If
any statute or rule governing a proceeding in which such liquidated final damages are to be proved shall validly limit the amount thereof
to an amount less than the amount above agreed upon, Lessor shall be entitled to the maximum amount allowable under such statute or rule
of law.

 

ARTICLE
22 - LIABILITY OF LESSOR

 

22.1     It is expressly agreed by the parties that in no case shall Lessor, any partners, officers, directors, managers, members, agents or employees
of Lessor be liable, under any express or implied covenant, agreement or provisions of this Lease, for any damages whatsoever to Lessee
beyond the loss of Rent reserved in this Lease, accruing after or upon any act or breach hereunder on the part of Lessor and for which
damages may be sought to be recovered against Lessor. Anything to the contrary notwithstanding, under no circumstances shall any personal
liability attach to or be imposed upon Lessor or any partners, officers, directors, managers, members, agents or employees of Lessor.
Lessee’s liability to Lessor for damages for default in payment of Rent or otherwise hereunder shall in all events survive the
termination by Lessor of this Lease or the termination by Lessor of Lessee’s right to possession only of the Demised Premises as
hereinabove provided.

 

ARTICLE
23 - CUMULATIVE REMEDIES OF LESSOR

 

23.1     The specific remedies to which Lessor may resort under the terms of this Lease are cumulative and are not intended to be exclusive of
any other remedies or means of redress to which Lessor may be lawfully entitled in case of any breach or threatened breach by Lessee
of any provision or provisions of this Lease. The failure of Lessor to insist, in any one or more cases, upon the strict performance
of any of the terms, covenants, conditions, provisions or agreements of this Lease, or to exercise any option herein contained, shall
not be construed as a waiver or relinquishment for the future of any such term, covenant, condition, provisions, agreement or option.

ARTICLE
24 - SECURITY FOR RENT

 

24.1     Lessor
shall have a first lien paramount to all others (except any Mortgage/Underlying Lease made by Lessor) on every right and interest of
Lessee in and to this Lease, and on any furnishings, equipment, fixtures, accounts receivable, certificates of need, licenses, provider
agreements, certifications, books, records and other property of any kind belonging to Lessee and used in connection with this Lease
or located at the Demised Premises. Such lien is granted for the purpose of securing the payments of Rent, charges, penalties, and damages
herein covenanted to be paid by Lessee, and for the purpose of securing the performance of all of Lessee’s obligations under this
Lease. Such lien shall be in addition to all rights to Lessor given and provided by law. This Lease shall constitute a security agreement
under the Uniform Commercial Code granting Lessor a security interest in any furnishings, equipment, fixtures, accounts receivable certificates
of need, licenses, provider agreements, certifications, books, records and other personal property of any kind belonging to Lessee, and
Lessee shall execute such other instruments and financing statements as Lessor may request to evidence or perfect said security interest.

 

24.2     Notwithstanding
the foregoing provisions of Section 24.1 of this Lease to the contrary, Lessor hereby agrees that it will subordinate its security interest
in the accounts receivable, licenses (only to the extent necessary to collect the accounts receivable and excluding all other underlying
bed operating rights), and provider agreements of Lessee to lenders of Lessee which are providing working capital to Lessee in connection
with Lessee’s operation of the Facilities (“Lessee’s Accounts Receivable Financing”). Lessor’s consent
and subordination to Lessee’s Accounts Receivable Financing shall be further subject to the following conditions precedent: (a)
there shall exist no Event of Default under this Lease nor any event or circumstance which with the passage of time or the giving of
notice or both shall constitute an Event of Default hereunder; and (b) Lessee’s Accounts Receivable Financing shall be from a bona
fide third party lender; and (c) Lessee’s Accounts Receivable lender shall execute and deliver to Lessor subordination documents
in form and substance reasonably satisfactory to Lessor.

 

ARTICLE
25 - INDEMNIFICATION

 

25.1     To the extent insurance proceeds do not cover same, Lessee agrees to protect, indemnify, save harmless and defend Lessor and its members,
managers, officers, agents, employees and any affiliates of the foregoing (each of the foregoing being, collectively, the “Lessor
Parties” and, individually, a “Lessor Party”) from and against any and all claims, demands and causes of action of
any nature whatsoever for injury to or death of persons or loss of or damage to property, occurring at the Demised Premises or any sidewalks,
alleyways, passageways, vacant land, streets or parking areas adjoining the Demised Premises, or in any manner growing out of or connected
with the use and occupation of the Demised Premises or the condition thereof, or the operation of Lessee’s business on the Demised
Premises, or the use of any existing or future sewer system, or the use of any such adjoining sidewalks, alleyways, passageways, vacant
land, streets or parking areas during the Term, and Lessee further agrees to pay any reasonable attorneys’ fees and expenses incident
to the defense by Lessor of any such claims, demands or causes of action.

26 - SUBORDINATION PROVISIONS

 

26.1     This Lease (and Lessee’s interest in the Leased Property) shall be subject and subordinate to any and all mortgages, deeds of trust,
ground leases or leases now or hereafter in force and affecting the Demised Premises (or any portion thereof) and/or Personal Property,
and to all renewals, modifications, consolidations, replacements and extensions thereof (any such mortgage, deed of trust, ground lease
or lease as it may be renewed, modified, consolidated, replaced and extended is hereinafter referred to as “a Mortgage/Underlying
Lease” or “any such Mortgage/Underlying Lease”, and the holder or beneficiary of a Mortgage/Underlying Lease is hereinafter
referred to as a “Mortgagee/Underlying Lessor”). Lessee agrees to execute and deliver upon demand such further instruments
subordinating this Lease to any such Mortgage/Underlying Lease, or other liens or encumbrances as shall be desired by Lessor; provided,
that Lessor shall use reasonable efforts to deliver to Lessee a nondisturbance agreement from any such Mortgagee/Underlying Lessor, in
form reasonably satisfactory to such Mortgagee/Underlying Lessor. Lessee further agrees that promptly after receipt of a request from
any Mortgagee/Underlying Lessor made at any time prior to foreclosure of its Mortgage/Underlying Lease, Lessee shall execute, acknowledge
and deliver to such Mortgagee/Underlying Lessor any instrument as such Mortgagee/Underlying Lessor may reasonably request whereby Lessee
agrees to subordinate and attorn to such Mortgagee/Underlying Lessor, at such Mortgagee/Underlying Lessor’s election, after the
foreclosure (or deed in lieu of foreclosure) of its Mortgage/Underlying Lease. Lessee agrees further that any Mortgagee/Underlying Lessor
shall have the right to subordinate its Mortgage/Underlying Lease and its rights thereunder to this Lease, except that such Mortgagee/Underlying
Lessor shall be entitled to expressly exclude from such subordination the Mortgagee/Underlying Lessor’s rights, if any, to insurance
proceeds and eminent domain awards in the event of a loss or casualty or eminent domain taking of the Leased Property, or any portion
thereof. If such Mortgagee/Underlying Lessor executes and records an instrument which purports to effect a partial or complete subordination
of its Mortgage/Underlying Lease to this Lease, this Lease shall not be terminated by a foreclosure of such Mortgage/Underlying Lease,
but any rights of such Mortgagee/Underlying Lessor to insurance proceeds or eminent domain awards which are expressly excluded from such
subordination shall remain superior to the rights of Lessee.

27 - LESSEE’S FAITHFUL

COMPLIANCE
WITH MORTGAGE/UNDERLYING LEASE

 

27.1     Anything in this Lease contained to the contrary notwithstanding, Lessee shall at all times and in all respects fully, timely and faithfully
comply with and observe each and all of the conditions, covenants, and provisions required on the part of Lessor under any Mortgage/Underlying
Lease to which this Lease is subordinate or to which it later may become subordinate, including, without limitation, such conditions,
covenants and provisions of such Mortgage/Underlying Lease which relate to the care, maintenance, repair, insurance, restoration, preservation
and condemnation of the Demised Premises notwithstanding that such conditions, covenants and provisions may require compliance and observance
to a standard or degree in excess of that required by the provisions of this Lease, or may require performance not required by the provisions
of this Lease, and shall not do or permit to be done anything which would constitute a breach of or default under any obligation of Lessor
under any Mortgage/Underlying Lease, it being the intention hereof that Lessee shall so comply with and observe each and all of such
covenants, conditions and provisions of any Mortgage/Underlying Lease so that they will at all times be in good standing and there will
not be any default on the part of Lessor under such Mortgage/Underlying Lease. However, nothing in this Article contained shall be construed
to obligate Lessee, except as may otherwise be provided in this Lease, to pay any Rent due or part of the principal or interest secured
by any Mortgage/Underlying Lease. Lessee further covenants and agrees as follows: (a) if requested by Lessor in writing, Lessee shall
give any Mortgagee/Underlying Lessor notice of any Lessor default which occurs under this Lease, (b) Lessee shall not terminate this
Lease as a result of Lessor’s default, without giving such Mortgagee/Underlying Lessor written notice of Lessor’s default
under this Lease at the same time that Lessor is given notice of such default, and (c) if Lessor fails to cure such default within the
applicable grace period, if any, contained in this Lease, such Mortgagee/Underlying Lessor shall have an additional period of time to
cure any such default.

conditions of any Mortgage/Underlying Lease, and the estate of Lessor thereunder is terminated by summary dispossession proceedings or
otherwise, Lessee will attorn to the then Mortgagee/Underlying Lessor or the purchaser in such foreclosure proceedings, as the case may
be, and will recognize such Mortgagee/Underlying Lessor or such purchaser as the lessor under this Lease. Lessee covenants and agrees
to execute and deliver, at any time and from time to time, upon the request of Lessor or of any Mortgagee/Underlying Lessor or the purchaser
in foreclosure proceedings, any instrument which may be necessary or appropriate to evidence such attornment. Lessee further waives the
provisions of any statute or rule of law now or hereafter in effect which may terminate this Lease or give or purport to give Lessee
any right of election to terminate this Lease or to surrender possession of the Demised Premises in the event any such proceedings are
brought against Lessor under such Mortgage/Underlying Lease or by any Mortgagee/Underlying Lessor, and agrees that this Lease shall not
be affected in any way whatsoever by any such proceedings.

credit in form in substance acceptable to Lessor, including, without limitation (i) issuance by an “A” rated financial institution,
(ii) an initial term of no less than one (1) year, (iii) automatic renewal for additional terms of no less than one (1) year unless the
issuing bank sends written notice to Lessor via certified mail of issuing bank’s intent elect not to renew such Letter of Credit,
and (iv) transferability by Lessor in connection with any transfer by Lessor of its interest in this Lease (individually and collectively,
as the context may require, the “Letter of Credit”), which Letter of Credit Lessor shall hold as security for the full and
faithful performance by Lessee of each and every term, provision, covenant and condition of this Lease. The Security Deposit may be applied
by Lessor for the purpose of curing any default or defaults of Lessee hereunder or as otherwise permitted hereunder, in which event Lessee
shall promptly replenish the Security Deposit in full by delivering an additional Letter of Credit in the amount so applied or, if acceptable
to Lessor in its sole discretion, by promptly paying to Lessor a cash Security Deposit in the amount so applied.

31.2     If
Lessor reasonably determines that the credit rating of the issuer of any Letter of Credit (or its holding company) has been reduced by
one or more nationally recognized credit rating agencies to a level lower than such agency’s or agencies’ “A”
rating, then at any time thereafter Lessor may give notice of such event to Lessee. Within thirty (30) days of the delivery of such notice
by Lessor, Lessee shall deliver or cause to be delivered to Lessor (a) a replacement Letter of Credit in form and substance consistent
with the requirements set forth in Section 31.1 in the amount of any Letter of Credit issued by the affected issuer or (b) if acceptable
to Lessor in its sole discretion, a cash Security Deposit in the amount of any Letter of Credit issued by the affected issuer.

 

31.3     Lessor
shall have the right to draw upon any Letter of Credit provided by Lessee to Lessor at any time from and after (i) a failure by Lessee
to deliver to Lessor a cash Security Deposit and/or a replacement Letter of Credit when and if and in the amounts required by Section
31.1 or Section 31.2 of this Lease; or (ii) Lessor’s receipt of a notice of non-renewal from the issuer of the Letter of Credit;

of (a) the dissolution, insolvency or business failure of Lessee, (b) an assignment for the benefit of creditors of Lessee, (c) the commencement
of any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding by or against Lessee, (d) the appointment
of a receiver for any property of Lessee or (e) the issuance of a writ of attachment or the enforcement of any order of any court of
legal process affecting any property of Lessee shall in any manner affect or impair any Letter of Credit or Lessor’s rights thereunder,
or under this Lease. Lessee acknowledges and agrees that (i) each Letter of Credit is a distinct and separate contract between Lessor
and the issuer thereof, (ii) each Letter of Credit is not and shall not be deemed or construed to be an asset, property, possession or
contract of any kind whatsoever owned or held by Lessee, (iii) any payments received by Lessor pursuant to any Letter of Credit shall
not constitute a preferential payment, and (iv) all funds paid by the issuer thereof pursuant to any Letter of Credit are the separate
funds of such issuer.

 

31.5     Lessee
shall bear all costs and expenses related to maintaining the Letter of Credit, including the fees of the financial institution that issues
any Letter of Credit. If at any time the Security Deposit is in the form of cash, Lessee shall not be entitled to any interest on the
Security Deposit and Lessor may commingle the Security Deposit with its other funds. The Security Deposit shall not be considered an
advance payment of Rent (or of any other sum payable by Tenant under this Lease) or a measure of Lessor’s damages in case of a
default by Lessee. The Security Deposit shall not be considered a trust fund, and Lessee expressly acknowledges and agrees that Lessor
is not acting as a trustee or in any fiduciary capacity in controlling or using the Security Deposit. Lessor shall have no obligation
to maintain the Security Deposit separate and apart from Lessor’s general and/or other funds. The Security Deposit, less any portion
thereof applied for the purposes of curing any default or defaults of Lessee hereunder, shall be returned to Lessee within one hundred

date on which (i) this Lease either terminates or expires pursuant to its terms or is terminated by either party whether pursuant to
a right granted to it hereunder or otherwise, (ii) the date on which Lessee’s right to possession of the Demised Premises is terminated
pursuant to a right granted to it hereunder or otherwise, or (iii) the date on which Lessee otherwise abandons the Demised Premises shall

claims, losses, costs or damages, including reasonable attorneys’ fees incurred or arising by reason of Lessee’s obligations
under the Intangibles prior to the Closing Date:

 

(1)       service
contracts and equipment leases for the benefit of the Demised Premises to which Lessee is a party, and which can be terminated without
penalty by Lessee within sixty (60) or fewer days’ notice or which Lessor requests be assigned to Lessor pursuant to this Article
36;

 

(2)       any
provider agreements with Medicare, Medicaid or any other third-party payor programs (excluding the right to any reimbursement for periods
prior to the Closing Date, as defined above) entered in connection with the Demised Premises to the extent assignable by Lessee;

 

(3)       all
existing agreements with residents of the Facilities and any guarantors thereof, to the extent assignable by Lessee (excluding the right
to any payments for periods prior to the Closing Date) and any and all patient trust fund accounts; and

 

    	29

     

    

 

(4)       at
Lessor’s option, the business of Lessee as conducted at the Demised Premises as a going concern, including but not limited to the
name of the business conducted thereon and all telephone numbers presently in use therein.

 

36.2     Lessor
shall be responsible for and shall pay all expenses with respect to the Demised Premises accruing on or after 12:01 a.m. on the day of
the Closing Date and shall be entitled to receive and retain all revenues from the Demised Premises accruing on or after the Closing
Date. Within fifteen (15) business days after the Closing Date, the following adjustments and prorations shall be determined as of the
Closing Date:

 

(1)       Taxes
and Assessments, if any. If the information as to the actual amount of any of the foregoing taxes and assessments are not available for
the tax year in which the Closing Date occurs, the proration of such taxes shall be estimated based upon reasonable information available
to the parties, including information disclosed by the local tax office or other public information, and an adjustment shall be made
when actual figures are published or otherwise become available.

 

(2)       Lessee
will terminate the employment of all employees on the Closing Date and shall be and remain liable for any and all wages, accrued vacation
and sick leave pay for employees of the Demised Premises with respect to the period prior to and including the Closing Date.

 

(3)       Lessor
shall receive a credit equal to any advance payments by patients of the Facilities to the extent attributable to periods on and after
the Closing Date.

 

(4)       The
present insurance coverage on the Demised Premises shall be terminated as of the Closing Date and there shall be no proration of insurance
premiums.

 

(5)       All
other income from, and expenses of, the Demised Premises (other than mortgage interest and principal), including but not limited to public
utility charges and deposits, maintenance charges and service charges shall be prorated between Lessee and Lessor as of the Closing Date.
Lessee shall, if possible, obtain final utility meter readings as of the Closing Date. To the extent that information for any such proration
is not available, Lessee and Lessor shall effect such proration within ninety (90) days after the Closing Date.

 

(6)       Lessee
shall be and remain responsible for any employee severance pay and accrued benefits which may be payable as the result of any termination
of an employee’s employment on or prior to the Closing Date.

 

36.3     All
necessary arrangements shall be made to provide possession of the Demised Premises to Lessor on the Closing Date, at which time of possession
Lessee shall deliver to Lessor all medical records, patient records and other personal information concerning all patients residing at
the Facilities as of the Closing Date and other relevant records used or developed in connection with the business conducted at the Demised
Premises. Such transfer and delivery shall be in accordance with all applicable laws, rules and regulations concerning the transfer of
medical records and other types of patient records.

 

    	30

     

    

 

36.4     For
the period commencing on the Closing Date and ending on the date Lessor, or its designee, obtains any and all appropriate state or other
governmental licenses and certifications required to operate the Facilities, Lessee hereby agrees that Lessor, or Lessor’s designee,
shall have the right, but not the obligation, to manage and operate the Demised Premises, on a triple net basis, and shall be entitled
to all revenues of the Demised Premises during such period, and to use any and all licenses, certifications and provider agreements issued
to Lessee by any federal, state or other governmental authority for such operation of the Demised Premises, if permitted by any such
governmental authorities. If Lessor or its designee exercises the right described above in this Section 36.4, the provisions of this
Section 36.4 shall be self-operative and shall constitute a management agreement between Lessee, on the one hand, and Lessor or its designee,
on the other hand, on the terms set forth above in this Section 36.4 provided, however, that upon the request of Lessor or its designee,
Lessee shall enter into a separate management agreement on the terms set forth in this Section 36.4 and on such other terms and provisions
as may be specified by Lessor or its designee.

 

36.5     Lessee
shall provide Lessor with an accounting within fifteen (15) days after the Closing Date of all funds belonging to patients at the Facilities
which are held by Lessee in a custodial capacity. Such accounting shall set forth the names of the patients for whom such funds are held,
the amounts held on behalf of each such patient and Lessee’s warranty that the accounting is true, correct and complete. Additionally,
Lessee, in accordance with all applicable rules and regulations, shall make all necessary arrangements to transfer such funds to a bank
account designated by Lessor, and Lessor shall in writing acknowledge receipt of and expressly assume all Lessee’s financial and
custodial obligations with respect thereto. Notwithstanding the foregoing, Lessee will indemnify, defend and hold Lessor and any other
Lessor Party harmless from and against all liabilities, claims and demands, including reasonable attorney’s fees, in the event
the amount of funds, if any, transferred to Lessor’s bank account as provided above, did not represent the full amount of the funds
then or thereafter shown to have been delivered to Lessee as custodian that remain undisbursed for the benefit of the patient for whom
such funds were deposited, or with respect to any matters relating to patient funds which accrued during the Term.

 

36.6     All
cash, checks and cash equivalent at the Demised Premises and deposits in bank accounts (other than patient trust accounts) relating to
the Demised Premises on the Closing Date shall remain Lessee’s property after the Closing Date. Subject to the provisions of Article
24 hereof, all accounts receivable, loans receivable and other receivables of Lessee, whether derived from operation of the Demised Premises
or otherwise, shall remain the property of Lessee after the Closing Date. Lessee shall retain full responsibility for the collection
thereof. Lessor shall assume responsibility for the billing and collection of payments on account of services rendered by it on and after
the Closing Date. In order to facilitate Lessee’s collection efforts, Lessee agrees to deliver to Lessor, within a reasonable time
after the Closing Date, a schedule identifying all of those private pay balances owing for the month prior to the Closing Date and Lessor
agrees to apply any payments received which are specifically designated as being applicable to services rendered prior to the Closing
Date to reduce the pre-Closing Date balances of said patients by promptly remitting said payments to Lessee. All other payments received
shall be retained by Lessor as being applicable to services rendered after the Closing Date. Lessor shall cooperate with Lessee in Lessee’s
collection of its preclosing accounts receivable. Lessor shall have no liability for uncollec- tible receivables and shall not be obligated
to bear any expense as a result of such activities on behalf of Lessee. Subject to the provisions of Article 24 hereof, Lessor
shall remit to Lessee or its assignee those portions of any payments received by Lessor which are specifically designated as repayment
or reimbursement arising out of cost reports filed for the cost reporting periods ending on or prior to the Closing Date.

 

    	31

     

    

 

36.7     With
respect to residents at the Facilities on the Closing Date, Lessor and Lessee agree as follows:

 

(1)       With respect to Medicare and Medicaid
residents, Lessor and Lessee agree that subject to the provisions of Article 24 hereof, payment for in-house residents covered by Medicare
or Medicaid on the Closing Date will be made (on a per diem basis) by Medicare or Medicaid under current regulations directly to Lessee
for services rendered at the Demised Premises prior to the Closing Date. Said payments shall be the sole responsibility of Lessee and
Lessor shall in no way be liable therefor. After the Closing Date, Lessor and Lessee shall each have the right to review supporting books,
records and documentation that are in the possession of the other relating to Medicaid or Medicare payments.

 

(2)       If,
following the Closing Date, Lessor receives payment from any state or federal agency or third-party provider which represents reimbursement
with respect to services provided at the Demised Premises prior to the Closing Date, Lessor agrees that, subject to the provisions of
Article 24 hereof, it shall remit such payments to Lessee. Payments by Lessor to Lessee shall be accompanied by a copy of the appropriate
remittance.

 

(3)       If,
following the Closing Date, Lessee receives payment from any state or federal agency or third-party provider which represents reimbursement
with respect to services provided at the Facilities on or after the Closing Date, Lessee agrees that, it shall remit such payments to
Lessor. Payments by Lessee to Lessor shall be accompanied by a copy of the appropriate remittance.

 

36.8     In
addition to the obligations required to be performed hereunder by Lessee and Lessor on and after the Closing Date, Lessee and Lessor
agree to perform such other acts, and to execute, acknowledge, and/or deliver subsequent to the Closing Date such other instruments,
documents and materials, as the other may reasonably request in order to effectuate the consummation of the transaction contemplated
herein, including but not limited to any documents or filings which may be required to be delivered by Lessee to Lessor or be filed in
order for the transaction contemplated hereunder to be in compliance with all local, state and federal laws, statutes, rules and regulations.

 

36.9     Lessee
for itself, its successors and assigns hereby indemnifies and agrees to defend and hold Lessor and the other Lessor Parties and their
respective successors and assigns harmless from and against any and all claims, demands, obligations, losses, liabilities, damages, recoveries
and deficiencies (including interest, penalties and reasonable attorney’s fees, costs and expenses) which any of them may suffer
as a result of the breach by Lessee in the performance of any of its commitments, covenants or obligations under this Article 36, or
with respect to any suits, arbitration proceedings, administrative actions or investigations which relate to the use by Lessee of the
Demised Premises during the Term or for any liability which may arise from operation of the Demised Premises as nursing homes during
the Term, including without limitation, any amounts due or to be reimbursed to any governmental authority based upon any audit or review
of Lessee or of the Facilities or the operation thereof and pertaining to the period prior to the Closing Date or any amounts recaptured
under Titles XVIII or XIX based upon applicable Medicaid/Medicare recapture regulations. The rights of Lessor under this paragraph are
without prejudice to any other remedies not inconsistent herewith which Lessor may have against Lessee pursuant to the terms of this
Lease. The foregoing indemnity shall survive the expiration or termination of this Lease, whether due to lapse of time or otherwise.

 

    	32

     

    

 

36.10   So
long as the termination of this Lease is not due to a default by Lessee hereunder and provided further that Lessee has performed in
accordance with Article 36 herein, Lessor for itself, its successors and assigns hereby indemnifies and agrees to defend and hold Lessee
and its successors and assigns harmless from any and all claims, demands, obligations, losses, liabilities, damages, recoveries and
deficiencies (including interest, penalties and reasonable attorney’s fees, costs and expenses) which any of them may suffer
as a result of the breach by Lessor in the performance of any of its commitments, covenants or obligations under this Article 36, or
with respect to any suits, arbitration proceedings, administrative actions or investigations which relate to the use of the Demised
Premises after the Term or for any liability which may arise from operation of the Demised Premises as nursing homes after the Term.
The rights of Lessee under this paragraph are without prejudice to any other remedies not inconsistent herewith which Lessee may
have against Lessor pursuant to the terms of this Lease or otherwise.

 

36.11   Lessor
shall have the right to offset against any monies due Lessee pursuant to the terms of this Article 36, any amounts due by Lessee to Lessor
pursuant to this Lease or due by Lessee to any third party, including without limitation any amounts due for taxes, utilities, unemployment
insurance premiums, payroll obligations or any other obligation arising from the operation of the Demised Premises.

 

36.12   Anything
to the contrary contained in this Article 36 notwithstanding, in the event the termination of this Lease is due to a default by Lessee
hereunder, none of the provisions of this Article 36 shall in any way limit, reduce, restrict or modify the rights granted to Lessor
pursuant to Articles 21, 23 and 24 of this Lease, and to the extent any monies are due to Lessee pursuant to this Article 36, such sums
shall be applied by Lessor to any damages suffered by Lessor as a result of Lessee’s default hereunder.

 

36.13   Lessor
and Lessee agree to cooperate with each other in order to effectuate the terms and provisions of this Article 36.

ARTICLE
38 - HAZARDOUS SUBSTANCES

 

38.1     Lessee
shall not install or permit to be installed in the Leased Property, any asbestos or asbestos-containing materials, nor install, permit
to be installed, generate, transport, store, treat or dispose of, at the Leased Property any asbestos or any substance containing asbestos
or hazardous substance (as hereinafter defined). With respect to any hazardous substance or condition, Lessee shall promptly either:
(a) remove or remediate any such hazardous substance or condition; or (b) otherwise comply with such federal, state or local laws, rules,
regulations or orders, in all such events at Lessee’s sole expense, and provide evidence thereof which is satisfactory to Lessor.
If Lessee shall fail to so remove or otherwise comply, Lessor may, after notice to Lessee and the expiration of the earlier of (i) the
applicable cure period hereunder or (ii) the cure period permitted under the applicable law, rule, regulation or order, either declare
this Lease to be in default or do whatever is necessary to remove or remediate said hazardous substance(s) or condition(s) from the Leased
Property or otherwise comply with the applicable law, rule, regulation or order, and Lessor’s costs and expenses in respect thereof
shall be due and payable upon demand. Lessee shall give to Lessor and its agents and employees access to the Leased Property for purposes
of removing or remediating said asbestos or other hazardous substance(s) or condition(s) and conducting appropriate tests for the purpose
of ascertaining compliance with the terms hereof. Lessee shall promptly provide Lessor copies of all communications, permits or agreements
with any governmental authority or agency (federal, state or local) or any private entity relating in any way to any hazardous substance
or condition.

 

    	33

     

    

 

38.2     For
purposes of this Article 38 “hazardous substance” means any material, chemical, compound or other substance defined or regulated
as a hazardous toxic or dangerous substance, waste, pollutant or material, or otherwise giving rise to liability, under the Resource
Conservation and Recovery Act (“RCRA”), 42 U.S.C. Section 6901 et seq., the Comprehensive Environmental Response,
Compensation and Liability Act (“CERCLA”), 52 U.S.C. Section 9601 et seq. or any other federal, state or local law,
ordinance or regulation relating to the protection of public health or safety, the environment or natural resources, including without
limitation any common law theory based on nuisance or strict liability (collectively, the “environmental laws”).

 

38.3     Lessee
shall not conduct or authorize the generation, transportation, storage, treatment or disposal at the Leased Property of any hazardous
substance, without prior written authorization by Lessor, and Lessee’s failure to comply with the foregoing prohibition shall constitute
a default under this Lease.

 

38.4     If
the presence, release, threat of release or placement on or in the Leased Property, or the generation, transportation, storage, treatment
or disposal at the Leased Property of any hazardous substance: (i) gives rise to liability (including, but not limited to, a response
action, remedial action or removal action) under any of the environmental laws, (ii) poses a significant threat to public health or safety,
or (iii) pollutes or threatens to pollute the environment, then Lessee shall promptly take any and all remedial and removal action necessary
to eliminate such liability, threat to public health or safety or pollution, as the case may be, and take all actions to mitigate to
the maximum extent possible, liability arising from the hazardous substance, whether or not required by law.

 

38.5     Lessee
shall defend (with counsel reasonably satisfactory to Lessor), indemnify the Lessor Parties and hold the Lessor Parties harmless from
and against all loss, cost, damage and expense (including, without limitation, attorneys’ fees and costs incurred in the investigation,
defense and settlement of claims) that any Lessor Party may incur as a result of or in connection with (a) the assertion against any
Lessor Party of any claim relating to the presence or removal of any asbestos or other hazardous substance at the Leased Premises, or
(b) failure of the Leased Premises on any portion of the Leased Premises to comply with any and all environmental laws, or (c) the breach
by Lessee of any of its covenants contained in this Article 38. The foregoing indemnity shall survive the expiration or termination of
this Lease whether due to the lapse of time or otherwise.

 

ARTICLE
39 - LIMITATION OF LESSOR’S LIABILITY

 

39.1    
In the event of any conveyance or other divestiture of title to the Leased Property the grantor or the person who is divested of
title shall be entirely freed and relieved of all covenants and obligations thereafter accruing hereunder, and the grantee or the
person who otherwise succeeds to title shall be deemed to have assumed the covenants and obligations of Lessor thereafter accruing
hereunder and shall then be Lessor under this Lease. Notwithstanding anything to the contrary provided in this Lease, if Lessor or
any successor in interest of Lessor shall be an individual, partnership, limited liability company, corporation, trust, tenant in
common or mortgagee, there shall be absolutely no personal, corporate or entity liability on the part of such Lessor or any
individual or member of Lessor or any manager, stockholder, director, officer, employee, partner or trustee of Lessor with respect
to the terms, covenants or conditions of this Lease, and Lessee shall look solely to the interest of Lessor in the Leased Property
for the satisfaction of each and every remedy which Lessee may have for the breach of this Lease; such exculpation from personal,
corporate or entity liability to be absolute and without any exception, whatsoever.

with a final written report which summarizes the activities undertaken and all accomplishments achieved under the Research Plan and the
Development Plans and contains all material results generated by Tango in the performance of the Research Plan and the Development Plans.
Such report shall be provided: (i) no later than [***] following the end of the Research Term; and (ii) where Tango conducts activities
assigned to it under the Development Plan with respect to any Extended Target following the expiration of the Research Term until the
expiration of the next Opt-In Period with respect to such Target, no later than [***] following the expiration of such Opt-In Period.
All such summaries and reports shall be deemed Collaboration Results, except as otherwise set forth in Section 1.47.

 

2.4 Conduct of Research
Collaboration.

 

2.4.1 Tango Conduct.
Tango:

 

(a) shall conduct its responsibilities
under the Research Collaboration as assigned to it under the Research Plan, the Development Plans, and this Agreement to achieve the
objectives and timelines within the Research Plan and the Development Plans for which it is responsible;

 

(b) shall perform (i) Research
Plan Screens and (ii) validation activities associated with Screen Hits arising from the Research Plan Screens referenced in subclause
(i), in each case ((i) and (ii)), as set forth in the Research Plan; provided, that the Parties agree to include in the Research
Plan at least [***] Research Plan Screens during each year of the Research Term, unless otherwise approved by the JSC;

 

(c) shall promptly, upon
Gilead’s Extension of a Target in accordance with Section 2.7 or Section 2.8.4 and the JSC’s approval of the Development
Plan therefor, initiate drug discovery or development activities for such Target in accordance with the applicable Development Plan;
provided, that Tango shall not be required, in a given Calendar Year, to: [***];

 

    29

     

    

 

(d) shall conduct the Research
Collaboration in compliance with all Applicable Laws; and

 

(e) may utilize the services
of any of its Affiliates and Third Parties to perform those activities assigned to it under the Research Collaboration (each, a “Subcontractor”);
provided, that (i) Tango shall remain responsible for the performance of such Subcontractors hereunder and (ii) the use of Third
Parties to design Research Plan Screens shall be subject to Gilead’s prior written consent, not to be unreasonably withheld, conditioned
or delayed.

 

As of the expiration of the
Research Term, Tango will continue to conduct the activities assigned to it under the Development Plan with respect to any Extended Target
until the earliest of: (i) the achievement of the next Opt-In Point with respect to such Extended Target, (ii) Gilead Opting-In to such
Extended Target or (iii) Gilead Declining such Extended Target. For clarity, any such Target shall remain an Extended Target until the
expiration of such period.

 

2.4.2 Gilead Conduct.
If and to the extent that Gilead is allocated responsibilities under the Research Collaboration, it: (a) shall conduct such activities
in compliance with all Applicable Laws; and (b) may utilize the services of any of its Affiliates and Third Parties to perform those
activities assigned to it under the Research Collaboration; provided, that Gilead shall remain responsible for the performance
of such Affiliates and Third Parties hereunder.

 

2.5 Screen Hits.

 

2.5.1 Promptly following
the completion of each Research Plan Screen, Tango shall submit to Gilead, in the manner described below, a written list of, and a summary
of material data with respect to, each screen hit identified through the performance of such Research Plan Screen which it proposes for
consideration to be deemed a Screen Hit by the JRDC, including a description of the process by which Tango determined the proposed Screen
Hit(s) to include on such list (each, a “Proposed Screen Hit List”). Tango shall disclose Proposed Screen Hit Lists
and the information therein only through the Controlled Disclosure Process.

 

2.5.2 The JRDC shall
review each Proposed Screen Hit List and: (i) approve which proposed Screen Hit(s) listed therein are Screen Hits; and (ii) make a recommendation
regarding which such Screen Hit(s) should proceed to validation. The JRDC shall then submit such recommendation regarding which such
Screen Hit(s) should proceed to validation to the JSC for the JSC’s approval. Upon such approval, Tango will proceed with validation
activities with respect to such approved Screen Hit(s). For clarity, the Proposed Screen Hit Lists (and any information therein) constitute
Collaboration Results, except as otherwise set forth in Section 1.47, and such validation activities shall be subject to the limitation
on simultaneous validation activities set forth in Section 2.3.1.

 

2.6 Disclosure of Opt-In
Point Achievement and Opt-In Data Packages. Tango will promptly (and, in any event, at least [***] before each meeting of the
JRDC) disclose to Gilead, through the Controlled Disclosure Process: (a) each Validated Target which has not yet been disclosed to Gilead
pursuant to this Section 2.6; (b) whether and for which Extended Target(s) an Opt-In Point has been achieved since the previous meeting
of the JDRC; and (c) with respect to any Validated Target referenced in sub-clause (a) and any Extended Target referenced in sub-clause
(b), the applicable Opt-In Data Package.

 

    30

     

    

 

2.7 Gilead Elections.

 

2.7.1 Opt-In Period Election.
Gilead will have the right, during each Opt-In Period, to Opt-In to, Extend, or Decline the applicable Target by providing written notice
thereof to Tango; provided, that, (a) Gilead will not have the right to Extend any Target at the Clinical POC Opt-In Point for
such Target or after the expiration of the Research Term and (b) Gilead shall have no further right to Opt-In to any Target after the
expiration of Research Term except with respect to any Extended Target that Gilead Extended prior to the expiration of the Research Term,
with respect to which Gilead may Opt-In prior to the expiration of the next Opt- In Period for such Extended Target. In the event that
Gilead does not provide any such notice to Tango prior to the expiration of the applicable Opt-In Period, then, upon such expiration,
Gilead shall be deemed to have Declined such Target.

 

2.7.2 Early Election.
Without limiting the foregoing in Section 2.7.1, Gilead will have the right, at any time prior to the next Opt-In Period with respect
to an Extended Target, to Opt-In to such Target by providing written notice thereof to Tango (each, an “Early Opt-In Point Notice”)
or Decline such Target by providing written notice thereof to Tango. For clarity, if Gilead Opts-In to or Declines an Extended Target,
then Tango shall have no obligation to conduct any further activities under the Development Plan for such Extended Target, and Gilead
shall remain obligated to pay Tango all unpaid Extension Fee Installments with respect to any Extension Fees triggered prior to such
Opt-In or Decline. Notwithstanding the prior sentence, if Gilead Opts-In to an Extended Target after the Clinical POC Opt-In Point, but
prior to the completion of the development activities described in the Development Plan for such Extended Target, then Tango shall complete
such activities in accordance with such Development Plan.

 

2.7.3 Gilead Request Notice.
From time to time during each Opt-In Period, Gilead may provide Tango with written notice requesting from Tango additional information
(including any raw data) with respect to, or the ability to discuss with Tango representative(s) who have knowledge of, in each case,
the applicable Opt-In Data Package (each, a “Gilead Request Notice”). Tango shall use reasonable efforts to provide
such information or hold such discussion as promptly as practicable but in any event within [***] after receipt of such Gilead Request
Notice; provided, that such additional information is in Tango’s or its Affiliate’s possession and does not require
the expenditure of additional funds or the performance of additional studies to generate. With respect to any Gilead Request Notice submitted
by Gilead during the first [***] of the applicable Opt-In Period, to the extent that Gilead reasonably determines that Tango has not
provided such information in any material respect or has failed to hold such discussion, Gilead shall notify Tango thereof and such Opt-In
Period shall be extended by a period corresponding to the number of days between the expiration of the [***] period following Tango’s
receipt of such Gilead Request Notice and the date such requested information is provided by Tango to Gilead, or such discussion is held
between the Parties.

 

2.7.4 Gilead Immediate Opt-In
Election. Without relieving Tango of any of its obligations under this Article 2, Gilead may in its sole discretion specify, in any
Opt-In notice provided in accordance with Section 2.7.1, any Early Opt-In Point Notice, or any Gilead Reserved Target Notice, as applicable,
that the applicable Opt-In shall be effective upon such notice and, in such case, Gilead shall be deemed to have Opted-In as of the date
thereof.

 

    31

     

    

 

2.8 Reserved Targets.

 

2.8.1 Reserved Target Election.
Concurrently with Gilead’s election to Decline a Validated Target (other than [***]and, to the extent applicable, [***]) during
the Target Validation Opt-In Period or an Extended Target prior to the expiration of the Extended Target Opt-In Period immediately following
the Lead Series Opt-In Point, as applicable, Gilead may provide written notice to Tango designating such Target as a Reserved Target.
Upon such designation and until expiration of the Reserved Target Period, such Target will be deemed a “Reserved Target.”
If Gilead does not provide any such notice to Tango concurrently with such a Decline election, then such Target shall not be a Reserved
Target and shall be deemed a Declined Target.

 

2.8.2 Reserved Target Limitation.
In the event that Gilead: (a) Declines a Target during the Target Validation Opt-In Period and designates such Target as a Reserved Target
in accordance with Section 2.8.1; and (b) later Extends such Target in accordance with Section 2.8.4, then, if Gilead Declines such Target
during the Extended Target Opt-In Period immediately following the Lead Series Opt-In Point, Gilead shall not be permitted to designate
such Target as a Reserved Target during such Extended Target Opt-In Period.

 

2.8.3 Reserved Target Withdrawal.
At any time following Gilead’s designation of a Target as a Reserved Target and prior to expiration of the applicable Reserved
Target Period, Gilead may withdraw such designation upon written notice to Tango, upon which such Target shall be deemed a Declined Target.

 

2.8.4 Reserved Target Opt-In
or Extension. At any time during the Reserved Target Period, Gilead may provide written notice to Tango that Gilead is Opting-In
to or Extending the applicable Reserved Target (each, a “Gilead Reserved Target Notice”). For purposes of the payment
of the applicable Opt-In Fee or Extension Fee for such Reserved Target, as applicable: (a) if Gilead had Declined such Target during
the Target Validation Opt-In Period, such Target will be considered a Validated Target; or (b) if Gilead had Declined such Target after
the expiration of the Target Validation Opt-In Period but prior to the expiration of the Extended Target Opt-In Period immediately following
the Lead Series Opt-In Point, such Target will be considered an Extended Target.

 

2.8.5 Program Option Target
Election. At any time during the Reserved Target Period, Tango may provide written notice to Gilead indicating that it wishes to
pursue drug discovery or development efforts itself (and not with any Third Party) with respect to the applicable Reserved Target; provided,
that Tango may not provide any such notice with respect to any Target for which Gilead has provided a Gilead Reserved Target Notice to
Tango in accordance with Section 2.8.4. Upon such notice from Tango, such Target shall be deemed a “Program Option Target.”

 

    32

     

    

 

2.9 Program Option.

 

2.9.1 Grant of Program Option.
Subject to this Section 2.9, Tango hereby grants to Gilead, on a Program Option Target-by-Program Option Target basis, a right of first
negotiation during the applicable Program Option Period for such Program Option Target (each, a “Program Option”).

 

2.9.2 Program Option Target
Restrictions. During the Program Option Period for a Program Option Target, Tango may pursue the development of products Directed
to the applicable Program Option Target on its own behalf but shall not collaborate or partner with any Third Party, grant a license
or other right to any Third Party, or acquire any license or other right from any Third Party, in each case, with respect to such Program
Option Target or products Directed to such Program Option Target.

 

2.9.3 Program Option Procedure.

 

(a) In the event that, at
any time during the Program Option Period: (i) Gilead is interested in [***]; or (ii) Tango [***] (any such license contemplated
by (i) and (ii), a “Program Option License”), the Parties will notify one another thereof (the “Program Option
Notice”). If Tango provides a Program Option Notice to Gilead, then such notice shall include a summary in reasonable detail
of the drug discovery or development efforts undertaken by Tango with respect to the applicable Program Option Target. For clarity: (x)
if neither Party provides a Program Option Notice for a Program Option Target prior to the expiration of such Program Option Period,
then, upon such expiration, such Target shall be deemed a Declined Target; and (y) if either Party provides a Program Option Notice for
a Program Option Target prior to the expiration of such Program Option Period, then the remainder of this Section 2.9.3 shall apply with
respect to such Program Option Target, regardless of whether the Research Term expires.

 

(b) If Gilead provides Tango
with the Program Option Notice, or provides Tango with written notice within [***] of the date of its receipt of a Program Option Notice
from Tango that Gilead wishes to negotiate with Tango to obtain a Program Option License, then, in each case, Tango shall disclose the
applicable Program Option Data Package to Gilead through the Controlled Disclosure Process. After providing such Data Package, Tango
shall, through the Controlled Disclosure Process, promptly provide Gilead with any additional information (including raw data and copies
of any Tango Third Party Agreements listed in the Data Package) reasonably requested by Gilead with respect to such Data Package (provided,
that such additional information is in Tango’s or its Affiliates’ possession or control and does not require the expenditure
of additional funds or the performance of additional studies to generate), or Tango shall notify Gilead in writing during such period
that neither Tango nor any of its Affiliates has such additional information in its possession or control, as applicable. Each such Data
Package and any such additional information shall be used by Gilead solely to determine whether to negotiate for, or the negotiation
of, a Program Option License with respect to the relevant Program Option Target unless and until the Parties enter into a Program Option
License with respect to such Target. With respect to copies of Tango Third Party Agreements provided under this Section 2.9.3, Tango
shall be entitled to redact from such copies terms which: (i) do not relate to any payment or other obligation that would be binding
upon Gilead or any of its Affiliates if the Parties were to enter into a Program Option License; or (ii) are not otherwise reasonably
relevant to Gilead’s determination as to whether to negotiate for (or the negotiation of) a Program Option License.

 

    33

     

    

 

(c) Following Gilead’s
receipt of the Program Option Data Package, the Parties shall exclusively negotiate in good faith, for a period of up to [***] (as such
period may be extended upon mutual agreement, the “Program Option License Negotiation Period”), the terms and conditions
of such Program Option License. If Gilead and Tango reach agreement on a Program Option License within such Program Option License Negotiation
Period, then such Program Option Target shall count towards the Gilead Target Limitation.

 

(d) For clarity, if either:
(i) Gilead does not provide Tango with a Program Option Notice, or written notice that Gilead wishes to negotiate with Tango to obtain
a Program Option License following its receipt of a Program Option Notice from Tango within the [***] period contemplated by Section
2.9.3(b); or (ii) Gilead and Tango do not enter into a Program Option License during the Program Option License Negotiation Period, then,
upon the expiration of either such period: (1) such Program Option Target shall be deemed a Declined Target; (2) subject to Section 2.10,
Tango shall be free to offer a Program Option License to any Third Party or otherwise continue the development and commercialization
of such Target, itself or with a Third Party; and (3) such Program Option Target shall not count towards the Gilead Target Limitation.
In addition, [***].

 

2.10 Tango Targets.

 

2.10.1 In General. Subject
to the terms and conditions of this Agreement (including Section 2.8.5, this Section 2.10, Section 5.5, and Section 5.6), Tango will
have the right to initiate and conduct, by or on behalf of itself or its Related Parties, a development and commercialization program
with respect to any Tango Target and associated Tango Products (excluding, for the avoidance of doubt, [***]) (each, a “Tango
Program”).

 

2.10.2 Tango Financial Target
Notice. In the event that, at any time during the Term, Tango wishes to initiate and conduct a development and commercialization
program with respect to any Target that [***], then it shall provide written notice thereof to Gilead, which notice shall identify the
applicable Target (each such notice, a “Tango Financial Target Notice”). Upon such notice or, without relieving Tango
of the foregoing obligation, in the event that Tango fails to provide such Tango Financial Target Notice, upon initiation of such development
or commercialization activities, such Target shall be deemed a “Tango Financial Target.”

 

2.10.3 Tango Target Limitation.
At any point in time during the Research Term, Tango shall not be permitted to simultaneously conduct a development program with respect
to more than [***] (the “Tango Target Limitation”).

 

2.11 Tango Independent
Targets.

 

2.11.1 In General. Tango
will, during the Research Term, retain the right to discover and validate Targets outside the scope of the Research Plan (any such validated
Targets, including the Targets listed on Exhibit 2.11.1, “Tango Independent Targets”), and such Targets shall not
be Validated Targets subject to this Agreement. Further, any Targets validated by Tango prior to the Original Effective Date (including
the Existing Programs) or after the Research Term shall be Tango Independent Targets and shall not be Validated Targets subject to this
Agreement. In addition, Tango will retain the right to pursue, independently from Gilead, development and commercialization activities
with respect to products Directed To Tango Independent Targets (such programs, “Tango Independent Programs”) at its
sole discretion. Tango will have the right to pursue an unlimited number of Tango Independent Programs.

 

    34

     

    

 

2.11.2 Third Parties.
If, during the Research Term, Tango executes an agreement, in compliance with this Agreement, granting a Third Party rights or licenses
with respect to any Tango screens (other than the Screens), then any screen hits and validated Targets resulting from those screens will
be Tango Independent Targets, and the development and commercialization activities with respect to products Directed To such Targets
will be Tango Independent Programs. Similarly, if Tango designs or develops any [***] screens with or for a Third Party during the Research
Term pursuant to an agreement with such Third Party, in compliance with this Agreement, such screens will not be in the scope of this
Agreement, any validated Targets resulting from such screens will be Tango Independent Targets, and the development and commercialization
activities with respect to products Directed To such Targets will be Tango Independent Programs.

 

2.11.3 Exclusivity.
This Section 2.11 is in all respects subject to Section 5.5.

 

2.12 Collaboration
Results. Tango shall maintain, and shall cause its Affiliates and their respective employees and permitted subcontractors to
maintain, records regarding its or their conduct of activities under the Research Collaboration, which may be in the form of electronic
lab notebooks that are segregated from other activities not performed under this Agreement, for so long as necessary after the applicable
activity to comply with Applicable Laws or to support the prosecution, maintenance and enforcement of intellectual property rights (including
Patent Rights) in accordance with Article 8, and as necessary in order to comply with its obligations under this Agreement, regarding
its conduct of the Research Collaboration, but in no event less than [***]. Such records shall be maintained in sufficient detail and
in good scientific manner appropriate for patent and regulatory purposes (and as otherwise necessary to comply with its obligations under
this Agreement) and shall reflect the work done by or on behalf of Tango in the performance of the Research Collaboration, including
all Collaboration Results. During such record retention period, Gilead shall have the right, during normal business hours and upon reasonable
notice not more than [***], to inspect and copy Collaboration Results.

 

2.13 Materials.
Gilead will transfer to Tango or its designee certain biological or chemical materials within Gilead’s or its Affiliates’
possession or control (the “Gilead Materials”) that are reasonably requested by Tango for the purpose of exercising
its rights or fulfilling its obligations under the Research Plan. All transfers of Gilead Materials by Gilead to Tango will be documented
in a material transfer agreement as agreed between the Parties, which will set forth the type and name of the Gilead Materials transferred,
the amount of the Gilead Materials transferred and the date of the transfer of such Gilead Materials. Tango will transfer to Gilead or
its designee certain biological or chemical materials within Tango’s or its Affiliates’ possession or control (the “Tango
Materials”) that are reasonably requested by Gilead for the purpose of exercising its rights or fulfilling its obligations
under this Agreement. All transfers of Tango Materials by Tango to Gilead, other than any Tango Materials which are transferred to Gilead
pursuant to Section 2.16, will be documented in a material transfer agreement as agreed between the Parties, which will set forth the
type and name of the Tango Materials transferred, the amount of the Tango Materials transferred and the date of the transfer of such
Tango Materials.

 

    35

     

    

 

2.14 Tango Third Party
Agreements.

 

2.14.1 In the event
that Tango proposes to enter into a Tango Third Party Agreement with respect to an Extended Target, Tango shall provide Gilead written
notice thereof and consult with and offer Gilead a reasonable opportunity to review and comment on such Tango Third Party Agreement to
the extent applicable to such Extended Target, including the scope of Tango Technology to be licensed with respect to such Extended Target
and the payment obligations thereunder with respect to such Extended Target.

 

2.14.2 With respect
to any Tango Technology that is the subject of a Tango Third Party Agreement, the inclusion of such Tango Technology in a License which
Gilead obtains pursuant to Opting-In to an Extended Target shall be subject to: (a) Gilead’s election in writing to include such
Tango Technology in such License in accordance with this Section 2.14.2; and (b) any and all applicable terms and conditions (including
restrictions and limitations) of the applicable Tango Third Party Agreement, including the pass through of any and all amounts payable
by Tango to the applicable Tango Licensor to the extent arising as a result of the development or commercialization by Gilead or any
of its Related Parties of the Gilead Products to which Gilead obtains a License pursuant to such Opt-In. Gilead may elect, in the relevant
Opt-In notice provided to Tango in accordance with Section 2.7, to include the relevant Tango Technology that is the subject of a Tango
Third Party Agreement within the scope of the License that Gilead would obtain pursuant to the relevant Opt-In. If Gilead elects not
to include such Tango Technology in such License, then such Tango Technology shall not be licensed to Gilead with respect to such Gilead
Products, shall not be included in the Tango Technology for purposes of such License, and the applicable Tango Third Party Agreement
shall cease to be a Tango Third Party Agreement for purposes of Section 13.3. If no notice of election or non-election is provided by
Gilead during an Opt-In Period as provided above, Gilead shall be deemed to have elected not to include such Tango Technology in such
License. The Parties will discuss in good faith the assignment to Gilead of any Tango Third Party Agreements that are specific to any
Gilead Product to which Gilead obtains a License pursuant to such Opt-In.

 

2.15 Antitrust Filings.

 

2.15.1 As soon as is
reasonably practicable following the date that Gilead Opts-In to a Target as contemplated under Section 2.7 (each, a “Target
Selection” and such date, the “Target Selection Date”) and in any event within [***] of such Target Selection
Date, each of Tango and Gilead shall prepare and submit any required (as reasonably determined by Gilead) filings, notices, applications
or other submissions under Antitrust Law (“Antitrust Filings”), including any required filings under the United States
Hart-Scott-Rodino Antitrust Improvements Act of 1976 (the “HSR Act”) and the rules promulgated thereunder, with respect
to such Target Selection. In connection with any such Antitrust Filings, the Parties shall furnish promptly to the United States Federal
Trade Commission (the “FTC”), the Antitrust Division of the United States Department of Justice (the “DOJ”)
and any other applicable governmental authority any additional information requested within their authority under the HSR Act or other
Antitrust Laws, use reasonable efforts to obtain antitrust clearance for the transactions contemplated hereunder as soon as practicable
with respect to such Target Selection, and otherwise cooperate with each other in the governmental antitrust clearance process. [***]
in connection with any filings under this Section 2.15, and each Party shall bear their respective attorneys’ fees and other expenses
in connection therewith.

 

    36

     

    

 

2.15.2 Solely to the
extent that a filing pursuant to the HSR Act or other Antitrust Laws is required in connection with a given Target Selection, Gilead’s
rights and obligations hereunder in connection with such Target Selection (including any licenses to be granted in connection therewith)
shall not become effective unless and until each of the following conditions are met: (a) the applicable waiting period provided by the
HSR Act shall have expired or been terminated (and all other required antitrust clearances have been obtained); (b) no court or administrative
challenges to such transaction are pending; and (c) no court or administrative orders are outstanding blocking the completion of the
transactions (the date on which such conditions are met with respect to such Target Selection or, if Gilead determines no Antitrust Filings
are required with respect to such Target Selection, the applicable Target Selection Date, the “Target Selection Effective Date”).
Nothing in this Agreement shall require or be deemed to require either Party (or their Affiliates) to commit to any divestitures or licenses
or agree to hold separate any assets or agree to any similar arrangements or commit to conduct its business in a specified manner, or
to submit and respond to a formal discovery procedure initiated by the FTC or DOJ or any other governmental authority (e.g., a
“Request for Additional Information and Documentary Materials,” also known as a “second request”, or Civil Investigative
Demand if a filing is not required under the HSR Act), in each case, as a condition to obtaining antitrust clearance for any Target Selection.

 

2.15.3 If the Target
Selection Effective Date for any Target Selection does not occur on or before [***] after the applicable Target Selection Date (each,
an “Initial Outside Date”), then Gilead may, in its sole discretion and only one time, provide written notice to Tango
on or prior to such Initial Outside Date to extend such Initial Outside Date by an additional [***] (each Initial Outside Date, as it
may be extended, if applicable, an “Outside Date”); provided, that Gilead may only extend the Initial Outside
Date if the Antitrust Filings are made within [***] of the applicable Target Selection Date and additional time is reasonably required
to respond to requests from FTC, DOJ, or any other applicable governmental authority in response to such Antitrust Filings.

 

2.15.4 If the Target
Selection Effective Date for any Target Selection does not occur on or before the applicable Outside Date, then: (a) the Target that
is the subject of such Target Selection shall not become a Gilead Target and shall not be included in the licenses and rights granted
to Gilead pursuant to Section 5.1 or counted toward the Gilead Target Limitation; (b) the Target that is the subject of such Target Selection
shall not be deemed a Declined Target; (c) neither Party nor such Party’s Affiliates will be restricted from researching, developing,
manufacturing or commercializing products Directed To the Target that is the subject of such Target Selection, subject to agreement on
financial terms and compliance with Antitrust Laws, as provided in Section 2.15.5; and (d) if the Research Term would have otherwise
expired prior to the Outside Date, then the Research Term will be extended for an additional [***] in order to allow Gilead to make an
alternative Target Selection from among the Reserved Targets, in its discretion.

 

2.15.5 Prior to initiating
any additional research, development, manufacturing or commercialization activities with respect to the applicable Target for which the
Target Selection Effective Date does not occur on or before the applicable Outside Date, either Party (the “Exploiting Party”)
shall give the other Party written notice that it is considering pursing such activities with respect to such Target. The Parties shall
thereafter negotiate in good faith the financial consideration to be paid by the Exploiting Party to the other Party in consideration
for the value provided by such other Party with respect to the applicable Target and the Parties will enter into an amendment to this
Agreement or another agreement providing for such financial terms and any other mutually agreed terms applicable to such activities by
the Exploiting Party with respect to such Target, including any such terms necessary to comply with Antitrust Laws.

 

    37

     

    

 

In the event that the Parties are unable to reach
such agreement within [***], either Party may submit such matter to baseball arbitration for resolution in accordance with Section 15.5.2;
provided, however, that such financial consideration shall not, in the aggregate, be more favorable to the other Party
than that which the other Party would have been entitled to receive under this Agreement if such Target were a Gilead Target (if Gilead
is the Exploiting Party) or a Tango Financial Target (if Tango is the Exploiting Party).

 

2.16 Technology Transfer.
Tango shall, as soon as reasonably practical after each Target Selection Effective Date, transfer to Gilead copies of or provide access
to (if copies cannot reasonably be made) all Tango Know-How to the extent related to the applicable Gilead Program in a format to be
mutually agreed by the Parties, including, at Gilead’s option, any and all inventory of compounds, molecules or products Directed
To the applicable Gilead Target. In addition, Tango will provide to Gilead all reports, Regulatory Materials (including any INDs or other
regulatory filings if permitted to be filed by Tango hereunder), manufacturing protocols, toxicology data, quality assurance and quality
control assays, contracts with contract research or manufacturing organizations, materials, assays, methods, data and results generated
by or on behalf of Tango or any of its Affiliates pursuant to this Agreement with respect to the applicable Gilead Program. The transfer
contemplated by this Section 2.16 will be conducted in accordance with a technology transfer plan and budget ([***]) to be agreed by
the Parties. Without limiting the foregoing, to the extent set forth in the technology transfer plan and, if applicable, budget, the
transfer contemplated by this Section 2.16 shall include: (a) providing reasonable access (including by telephone and email) to a reasonable
number of qualified scientists, production, quality assurance, and quality control personnel, and engineers; (b) allowing reasonable
access to the manufacturing sites (whether those of Tango or a contract manufacturing organization) involved in the manufacture of compounds,
molecules or products with respect to the Gilead Program; and (c) any other reasonable support or training reasonably requested by Gilead
to facilitate such transfer. For clarity and notwithstanding the foregoing in Section 2.13, the Parties will not be required to enter
into a material transfer agreement in connection with any transfer contemplated by this Section 2.16. With respect to any Gilead Target
for which Gilead Opts-In [***], Tango will perform such technology transfer at no additional cost to Gilead. With respect to any other
Gilead Target, Tango may invoice Gilead for any reasonable out-of-pocket costs incurred by Tango in the performance of such technology
transfer and contemplated by the applicable budget, and Gilead shall pay such invoice within [***] after receipt.

3.1 Gilead Development.

 

3.1.1 General. Gilead
(itself or through any of its Affiliates or Third Parties) shall have the sole responsibility and exclusive right, at its cost, to conduct
all development, manufacturing and regulatory activities worldwide for: (a) Gilead Products, during the applicable Gilead Target Exclusivity
Period; and (b) Gilead Financial Products, following the expiration of the applicable Gilead Target Exclusivity Period; provided,
that, in each case ((a) and (b)), if Tango exercises the Co-Detail Option with respect to a Co-Detail Eligible Gilead Financial Product,
then Tango will share Development Costs with respect to such Product in accordance with Section 6.5 and the terms of the applicable Joint

3.5.1, any such notice delivered by Gilead to Tango shall constitute a Gilead Registrational Clinical Trial Notice.

 

(e) Co-Detail Option Data
Package. At any time prior to the expiration of the [***] period following Tango’s receipt of the Gilead Registrational Clinical
Trial Notice, Tango may request (and Gilead will provide to Tango within a reasonable period of time) a Co-Detail Option Data Package
for the applicable Product. Tango shall use such Data Package (and any additional information provided by Gilead pursuant to this Section

Gilead shall use reasonable efforts to provide such information or hold such discussion as promptly as practicable but in any event within
[***] after receipt of such Co-Detail Information Request; provided, that such additional information is in Gilead’s or

(a) Each Party (the “Auditing
Party”) shall have the right during the [***] period described in Section 7.4.1 to appoint at its expense an independent certified
public accountant of nationally recognized standing (the “Accounting Firm”) reasonably acceptable to the other Party
(the “Audited Party”) to inspect or audit the relevant records of the Audited Party and its Related Parties to verify
that the amount of such payments were correctly determined; provided, that (except in the event of a dispute as set forth in the
second-to-last sentence of this Section 7.4.2(a)) records for a particular period may only be audited once. The Auditing Party will provide
the Audited Party with at least [***] notice of its desire to initiate an audit. The Audited Party and its Related Parties shall each
make their records available for inspection or audit by the Accounting Firm during regular business hours for a period of [***] from
the creation of individual records at such place or places where such records are customarily kept, upon reasonable notice from Auditing
Party, solely to verify the payments hereunder were correctly determined. Such inspection or audit right shall not be exercised by the
Auditing Party more than [***] in any Calendar Year and may cover a period ending not more than [***] prior to the date of such request.
All records made available for inspection or audit pursuant to this Section 7.4.2 shall be deemed to be Confidential Information of the
Audited Party. Any undisputed amounts shown to be owed but unpaid, or overpaid and in need of refund, shall be paid or refunded (as the
case may be) within [***] after the delivery of the Accounting Firm’s report. If the Audited Party disputes amounts owed, as set
forth in an audit report generated pursuant to this Section 7.4.2, then the Audited Party shall have a second audit of such records conducted
solely to verify that the disputed amounts owed hereunder were correctly determined, at the Audited Party’s expense, by an Accounting
Firm reasonably acceptable to the other Party, and the results of such second audit shall be binding on the Parties; provided,
that to the extent such dispute constitutes a Dispute as to whether to underlying payment obligation has been triggered, it shall be
resolved in accordance with Section 15.5. Except as otherwise set forth in the foregoing sentence, the Auditing Party shall bear the
full cost of an audit that it conducts pursuant to this Section 7.4.2 unless such audit discloses an under reporting by the Audited Party
of more than [***] of the aggregate amount of the payments hereunder reportable in any Calendar Year, in which case the Audited Party
shall reimburse the Auditing Party for all costs incurred in connection with such inspection or audit.

 

(b) The Accounting Firm will
disclose to the Auditing Party only whether the payments subject to such audit are correct or incorrect and the specific details concerning
any discrepancies. No other information will be provided to the Auditing Party without the prior consent of the Audited Party unless
disclosure is required by Applicable Laws or judicial order. The Audited Party is entitled to require the Accounting Firm to execute
a reasonable confidentiality agreement prior to commencing any such audit. The Accounting Firm shall provide a copy of its report and
findings to Audited Party.

14.3.1 Any Gilead Indemnified
Party or Tango Indemnified Party seeking indemnification hereunder (“Indemnified Party”) shall notify the Party against
whom indemnification is sought (“Indemnifying Party”) in writing reasonably promptly after the assertion against the
Indemnified Party of any Third Party Claim with respect to which the Indemnified Party intends to base a claim for indemnification hereunder,
but the failure or delay to so notify the Indemnifying Party shall not relieve the Indemnifying Party of any obligation or liability
that it may have to the Indemnified Party except to the extent that the Indemnifying Party demonstrates that its ability to defend or
resolve such Third Party Claim is adversely affected thereby.

 

14.3.2 Subject to Section
14.3.3, the Indemnifying Party shall have the right, upon providing notice to the Indemnified Party of its acceptance of responsibility
to indemnify the Indemnified Party and its intent to do so within [***] after receipt of the notice from the Indemnified Party of any
Third Party Claim, to assume the defense and handling of such Third Party Claim, at the Indemnifying Party’s sole expense.

 

14.3.3 The Indemnifying
Party shall select counsel reasonably acceptable to the Indemnified Party in connection with conducting the defense and handling of such
Third Party Claim, and the Indemnifying Party shall defend or handle the same in consultation with the Indemnified Party, and shall keep
the Indemnified Party timely apprised of the status of such Third Party Claim. The Indemnifying Party shall not, without the prior written
consent of the Indemnified Party, agree to a settlement of any Third Party Claim which imposes any liability or obligation on the Indemnified
Party other than financial obligations which are fully assumed by the Indemnifying Party, would involve any admission of wrongdoing on
the part of the Indemnified Party, or does not include a release of all claims against the Indemnified Party. The Indemnified Party shall
cooperate with the Indemnifying Party (at the Indemnifying Party’s request and subject to reimbursement of associated out-of-pocket
expenses by the Indemnifying Party), shall be entitled to participate in the defense and handling of such Third Party Claim with its
own counsel and at its own expense and shall not make any admission or other communication regarding such Third Party Claim or agree
to a settlement of any Third Party Claim without the consent of the Indemnifying Party.

(A) BREACH OF ARTICLE 9, SECTION 5.5 OR SECTION 5.6; OR (B) A PARTY’S GROSS NEGLIGENCE, INTENTIONAL MISCONDUCT, OR FRAUD. NOTHING

GENERAL PROVISIONS

 

15.1 Assignment.
Except as provided in this Section 15.1, this Agreement may not be assigned or otherwise transferred, nor may any right or obligation
hereunder be assigned or transferred, by either Party without the consent of the other Party; provided, however, that (and notwithstanding
anything elsewhere in this Agreement to the contrary) either Party may, without such consent, assign this Agreement and its rights and
obligations hereunder in whole or in part: (a) to an Affiliate of such Party; (b) in connection with the transfer or sale of all or substantially
all of its assets or business related to the subject matter of this Agreement; or (c) pursuant to a merger or consolidation (or similar

that, during the Research Term, an assignment by Tango pursuant to Section 15.1(b) shall be subject to Gilead’s prior written consent,
not to be unreasonably withheld, conditioned or delayed.

 

    83

     

    

 

15.2 Extension to Affiliates.
Except as expressly set forth otherwise in this Agreement, each Party shall have the right to extend the rights and obligations granted
in this Agreement to one (1) or more of its Affiliates. All applicable terms and provisions of this Agreement, except this right to extend,
shall apply to any such Affiliate to which this Agreement has been extended to the same extent as such terms and provisions apply to
the Party extending such rights and obligations. The Party extending the rights and obligations granted hereunder shall remain primarily
liable for any acts or omissions of any of its Affiliates.

 

15.3 Severability.
Should one (1) or more of the provisions of this Agreement become void or unenforceable as a matter of Applicable Laws, then this Agreement
shall be construed as if such provision were not contained herein and the remainder of this Agreement shall be in full force and effect,
and the Parties will use their best efforts to substitute for the invalid or unenforceable provision a valid and enforceable provision
which conforms as nearly as possible with the original intent of the Parties.

 

15.4 Governing Law;
English Language. This Agreement shall be governed by and construed in accordance with the laws of the State of New York and,
to the extent applicable, the patent laws of the United States without reference to any rules of conflict of laws. This Agreement was
prepared in the English language, which language shall govern the interpretation of, and any dispute regarding, the terms of this Agreement.

 

15.5 Dispute Resolution.

 

15.5.1 The Parties recognize
that disputes as to certain matters may from time to time arise that relate to either Party’s rights or obligations hereunder,
including the interpretation, alleged breach, enforcement, termination or validity of this Agreement (a “Dispute”).
For clarity, Disputes shall not include matters within the JSC’s authority, which shall be resolved in accordance with Section
4.5, any Short-Form Dispute, which shall be resolved in accordance with Section 15.5.2, or any dispute with respect to a financial audit,
which shall be resolved in accordance with Section 7.4.2. If a Dispute arises under this Agreement, and the Parties are unable to resolve
such Dispute within [***] after such Dispute is first identified by either Party in writing to the other Party, the Parties shall refer
such Dispute to the Executive Officers of the Parties for attempted resolution by good faith negotiations. If the Executive Officers
are not able to resolve such Dispute within [***], then either Party shall be entitled to seek all available remedies, subject to Section
15.6. Notwithstanding the foregoing, and without waiting for the expiration of the time periods set forth above or elsewhere in this
Agreement, each Party shall have the right to apply to any court of competent jurisdiction for appropriate interim or provisional relief,
as necessary to protect its rights or property.

 

    84

     

    

 

15.5.2 Any inability
for the Parties to agree upon the [***] (each, a “Short-Form Dispute”) shall be finally determined by binding arbitration
in accordance with this Section 15.5.2 by a single arbitrator, which arbitrator shall be neutral and independent of the Parties and all
of their respective Affiliates, shall have significant experience and expertise in the development of [***]. Any such arbitration shall
be administered by Judicial Arbitration and Mediation Services (“JAMS”) and shall be seated in New York, New York
in accordance with the applicable JAMS Streamlined Arbitration Rules, except as expressly set forth herein. If the Parties are unable
to agree on an arbitrator within [***] of request by a Party for arbitration, the arbitrator shall be selected by JAMS. Each Party to
the arbitration shall prepare a written proposal setting forth its position with respect to the substance of the Short-Form Dispute.
Without delaying the arbitration procedures, for a period not to exceed [***] commencing no later than [***] after the arbitrator has
been selected, the Parties shall exchange and discuss the Parties’ respective written proposals in good faith in an effort to resolve
the matter. The arbitrator shall select one of the requested proposals as her/his decision, and shall not have authority to render any
substantive decision other than to so select the proposal of one of the Parties. If one Party does not submit to the arbitrator a written
proposal setting forth its position within the time period established by the arbitrator therefor, the arbitrator shall select the other
Party(ies)’ proposal. The costs of such arbitration shall be shared equally by the Parties, and each Party shall bear its own costs
and expenses in connection with the arbitration. The Parties shall use good faith efforts to complete arbitration under this Section
15.5.2 within [***] following the initiation of such arbitration. The arbitrator shall establish reasonable additional procedures to
facilitate and complete such arbitration within such [***] period. The existence of any arbitration and all submissions, correspondence
and evidence relating to such arbitration shall constitute the Confidential Information of each Party, and this provision shall survive
the termination of any arbitration.

 

15.6 Jurisdiction.
The Parties hereby irrevocably submit to the exclusive jurisdiction of the Federal courts of the United States of America located in
the State of New York (and, if such courts are unavailable, State courts of the State of New York), with respect to, subject to Section
15.5.1, any Dispute, the documents referred to in this Agreement, and the transactions hereby and thereby, and hereby waive, and agree
not to assert, as a defense in any action, suit or proceeding for the interpretation or enforcement hereof or thereof, that it is not
subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that the venue thereof
may not be appropriate or that this Agreement or any such document may not be enforced in or by such courts, and the Parties irrevocably
agree that all claims with respect to such action, suit or proceeding shall be heard and determined in such Federal court or New York
State court. The Parties hereby consent to and grant any such court jurisdiction over the person of such Parties and over the subject
matter of such dispute and agree that mailing of process or other papers in connection with any such action or proceeding in the manner
provided in Section 15.10 or in such other manner as may be permitted by Applicable Laws shall be valid and sufficient service thereof.
With respect to any particular action, suit or proceeding, venue shall lie solely in United States District Court for the Southern District
of New York located in New York City (or, if, and only if, such court does not have jurisdiction over the claim, the state courts of
the State of New York located in New York City). A Party hereto may apply either to a court of competent jurisdiction for prejudgment
remedies and emergency relief pending final determination of a claim pursuant to this Section 15.6.

 

    85

     

    

 

15.7 Force Majeure.
Neither Party shall be responsible to the other for any failure or delay in performing any of its obligations under this Agreement or
for other nonperformance hereunder (excluding, in each case, the obligation to make payments when due) if such delay or nonperformance
is caused by strike, fire, flood, earthquake, accident, war, act of terrorism, pandemic, act of God or of the government of any country
or of any local government, or by any other cause unavoidable or beyond the reasonable control of any Party. In such event, the Party
affected will use reasonable efforts to resume performance of its obligations as soon as possible and will keep the other Party informed
of actions related thereto. If any such failure of delay in a Party’s performance hereunder continues for more than [***], the
other Party may terminate this Agreement upon written notice to the delayed Party.

 

15.8 Waivers and Amendments.
The failure of any Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall
not constitute a waiver of that right or excuse a similar subsequent failure to perform any such term or condition by the other Party.
No waiver shall be effective unless it has been given in writing and signed by the Party giving such waiver. No provision of this Agreement
may be amended or modified other than by a written document signed by authorized representatives of each Party.

 

15.9 Relationship of
the Parties. Nothing contained in this Agreement shall be deemed to constitute a partnership, joint venture, or legal entity
of any type between Tango and Gilead, or to constitute one as the agent of the other. Each Party shall act solely as an independent contractor,
and nothing in this Agreement shall be construed to give any Party the power or authority to act for, bind, or commit the other Party.
The Parties do not intend for this Agreement or any Joint Development and Co-Detail Agreement to be treated as a creating a partnership
for taxation purposes.

duly given when: (a) delivered in person; or (b) when delivered by registered letter or overnight courier by an internationally recognized
