-2-

--------------------------------------------------------------------------------

Permitted Assignment. In the event of any assignment of the Lease (other than a
Permitted Assignment) or subletting (other than a Permitted Sublease) of the
Premises or any part thereof, the First Extension Option shall automatically
terminate and shall thereafter be null and void.

(d) Tenant's exercise of the First Extension Option shall, if Landlord so elects
in its absolute discretion, be ineffective in the event that a Default by Tenant
remains uncured at the time of delivery of the First Exercise Notice or at the
commencement of the First Extension Period.

41.2 Second Extension Option. Tenant shall have the option to extend this Lease
(the "Second Extension Option") for one additional term of five (5) years (the
"Second Extension Period"), upon the terms and conditions hereinafter set forth:

(a) If the Second Extension Option is exercised, then the Basic Annual Rent per
annum for such Second Extension Period (the "Second Option Rent") shall be equal
to 95% of the Fair Market Rental Value for the Premises as of the commencement

is personal to Tenant and is not transferable except in connection with a

Permitted Assignment) or subletting (other than a Permitted Sublease) of the
Premises or any part thereof, the Second Extension Option shall automatically
terminate and shall thereafter be null and void.

Tenant remains uncured at the time of delivery of the Second Exercise Notice or
at the commencement of the Second Extension Period.

(e) The Second Extension Option shall terminate and shall thereafter be null and
void in the event Tenant does not exercise the First Extension Option or for any
reason Tenant's exercise of the First Extension Option is ineffective.

41.3 Fair Market Rental Value. The provisions of this Section shall apply in any
instance in which this Lease provides that the Fair Market Rental Value is to
apply.

(a) "Fair Market Rental Value" means the annual amount per square foot that a
willing tenant would pay and a willing landlord would accept in arm's length
negotiations, without any additional inducements, for an extension of a lease of
the applicable space on the applicable terms and conditions for the applicable
period of time (other than Base Year, which shall be the calendar year in which
the first day of the applicable Extension Period falls). Fair Market Rental
Value shall be determined by Landlord considering the most recent new direct
leases (and market renewals and extensions, if applicable) in the Building and
in comparable buildings owned or managed by Landlord that are near the Building,
and consideration shall be given to the most recent new direct leases (and
market renewals and extensions, if applicable) in other comparable buildings in
the Harbor Bay area.

(b) In determining the rental rate of comparable space, the parties shall
include all escalations and take into consideration the following concessions:

(i) Rental abatement concessions, if any, being granted to tenants in connection
with the comparable space;

(ii) Tenant improvements or allowances provided or to be provided for the
comparable space, taking into account the value of the existing improvements in
the Premises, based on the age, quality, and layout of the improvements.

(c) If in determining the Fair Market Rental Value the parties determine that
the economic terms of leases of comparable space include a tenant improvement
allowance, Landlord may, at Landlord's sole option, elect to do the following:

(i) Grant some or all of the value of the tenant improvement allowance as an
allowance for the refurbishment of the Premises; and

 

-4-

--------------------------------------------------------------------------------

(ii) Reduce the Basic Annual Rent component of the Fair Market Rental Value to
be an effective rental rate that takes into consideration the total dollar value
of that portion of the tenant improvement allowance that Landlord has elected
not to grant to Tenant (in which case that portion of the tenant improvement
allowance evidenced in the effective rental rate shall not be granted to
Tenant).

41.4 Resolving Disagreement Over Fair Market Rental Value. The determination of
Fair Market Rental Value shall be as provided this Section 41.4.

(a) Negotiated Agreement. Landlord and Tenant shall diligently attempt in good
faith to agree on the Fair Market Rental Value on or before the date that is one
hundred twenty (120) days prior to the commencement of the applicable Extension
Option (the "Outside Agreement Date").

(b) Parties' Separate Determinations. If Landlord and Tenant fail to reach
agreement on or before the Outside Agreement Date, Landlord and Tenant shall
each make a separate determination of the Fair Market Rental Value and notify
the other party of this determination within five (5) days after the Outside
Agreement Date.

(i) Two Determinations. If each party makes a timely determination of the Fair
Market Rental Value, those determinations shall be submitted to arbitration in
accordance with subsection (c).

(ii) One Determination. If Landlord or Tenant fails to make a determination of
the Fair Market Rental Value within the five-day period, that failure shall be
conclusively considered to be that party's approval of the Fair Market Rental
Value submitted within the five-day period by the other party.

(c) Arbitration. If both parties make timely individual determinations of the
Fair Market Rental Value under subsection (b), the Fair Market Rental Value
shall be determined by arbitration under this subsection (c).

(i) Scope of Arbitration. The determination of the arbitrators shall be limited
to the sole issue of whether Landlord's or Tenant's submitted Fair Market Rental
Value is the closest to the actual Fair Market Rental Value as determined by the
arbitrators, taking into account the requirements of Section 41.3.

(ii) Qualifications of Arbitrator(s). The arbitrators (i) shall be (A) a member
of the American Institute of Real Estate Appraisers with not less than 10 years
of experience in the appraisal of improved office, R&D and office/laboratory
real estate in the greater San Francisco Bay metropolitan area, or (B) a
licensed commercial real estate broker with not less than 15 years experience
representing landlords and/or tenants in the leasing of high tech or life
sciences space in the greater San Francisco Bay metropolitan area, (ii) devoting
substantially all of their time to professional appraisal or brokerage work, as
applicable, at the time of appointment and (iii) be in all respects impartial
and disinterested.

 

-5-

--------------------------------------------------------------------------------

(iii) Parties' Appointment of Arbitrators. Within fifteen (15) days after the
Outside Agreement Date, Landlord and Tenant shall each appoint one arbitrator
and notify the other party of the arbitrator's name and business address.

(iv) Appointment of Third Arbitrator. If each party timely appoints an
arbitrator, the two (2) arbitrators shall, within ten (10) days after the
appointment of the second arbitrator, agree on and appoint a third arbitrator
(who shall be qualified under the same criteria set forth above for
qualification of the initial two (2) arbitrators) and provide notice to Landlord
and Tenant of the arbitrator's name and business address.

(v) Arbitrators' Decision. Within thirty (30) days after the appointment of the
third arbitrator, the three (3) arbitrators shall decide whether the parties
will use Landlord's or Tenant's submitted Fair Market Rental Value and shall
notify Landlord and Tenant of their decision. The decision of the majority the
three (3) arbitrators shall be binding on Landlord and Tenant.

(vi) If Only One Arbitrator is Appointed. If either Landlord or Tenant fails to
appoint an arbitrator within fifteen (15) days after the Outside Agreement Date,
the arbitrator timely appointed by one of them shall reach a decision and notify
Landlord and Tenant of that decision within thirty (30) days after the
arbitrator's appointment. The arbitrator's decision shall be binding on Landlord
and Tenant.

(vii) If Only Two Arbitrators Are Appointed. If each party appoints an
arbitrator in a timely manner, but the two (2) arbitrators fail to agree on and
appoint a third arbitrator within the required period, the arbitrators shall be
dismissed without delay and the issue of Fair Market Rental Value shall be
submitted to binding arbitration under the real estate arbitration rules of
JAMS, subject to the provisions of this section.

(viii) If No Arbitrator Is Appointed. If Landlord and Tenant each fail to
appoint an arbitrator in a timely manner, the matter to be decided shall be
submitted without delay to binding arbitration under the real estate arbitration
rules of JAMS subject the provisions of this Section 41.4(c).

(ix) Cost of Arbitration. The cost of the arbitration shall be paid by the
losing party."

7. The following new Sections 44, 45 and 46 are added to the Lease:

"44. Tenant's Right of First Offer.

44.1 As used herein, "Offer Space" means space in the buildings known as 1301
Harbor Bay Parkway and 1431 Harbor Bay Parkway, Alameda, California, so long as
they are owned by Landlord. Tenant shall have a continuing right of first offer
on any Available (as defined below) Offer Space during the Term. Landlord may
from time to time give Tenant a written notice (the "Availability Notice")
identifying the particular Offer Space (the "Specific Offer Space") that is
Available (as defined below). As used herein, "Available" means that the space
(i) is not part of the Premises, (ii) is not then subject to a lease, (iii) is
not then subject to any rights of a tenant to renew their lease or expand their
premises as set forth in their lease, and (iv) is not then subject to any
negotiations between Landlord and an existing tenant of that space. Tenant's
rights under this Section 44 shall terminate and be of no further force or
effect upon Tenant's delivery of notice of its exercise of its termination right
under Section 45 of this Lease.

44.2 Tenant may inform Landlord (the "Request Notice") not more than twice in
any twelve (12) month period and not within three (3) months after receipt of an
Availability Notice that Tenant desires to lease additional space. Landlord
shall, within ten (10) business days of receiving the properly given Request
Notice, deliver to Tenant an Availability Notice identifying Specific Offer
Space that is Available.

44.3 The location and configuration of the Specific Offer Space shall be
determined by Landlord in its reasonable discretion; provided that Landlord
shall have no obligations to designate Specific Offer Space that would result in
any space not included in the Specific Offer Space being not Configured For
Leasing (as defined below). For purposes of this Lease, "Configured For Leasing"
means the applicable space must have convenient access to the central corridor
on the applicable floor and must have a size and configuration that complies
with all applicable building codes and other laws and is such that Landlord
judges, in its reasonable discretion, that Landlord will be able to lease such
space to a third party. The Availability Notice shall:

(a) Describe the particular Specific Offer Space (including rentable area,
usable area and location);

(b) Include an attached floor plan identifying such space;

(c) State the date (the "Specific Offer Space Delivery Date") the space will be
available for delivery to Tenant; and

(d) Specify the Basic Annual Rent for the Specific Offer Space.

(e) Specify the increase in the security deposit that will apply to reflect the
addition of the Specific Offer Space to the Premises.

(f) If the Specific Offer Space Delivery Date is after the third (3rd)
anniversary of the Extension Commencement Date, specify the length of the term
of the leasing of the Specific Offer Space that will be available (the "Specific
Offer Space Term").

 

-7-

--------------------------------------------------------------------------------

44.4 If Tenant wishes to exercise Tenant's rights set forth in this Article 44
with respect to the Specific Offer Space, then within five (5) business days of
delivery of the Availability Notice to Tenant, Tenant shall deliver irrevocable
notice to Landlord (the "First Offer Exercise Notice") offering to lease the
Specific Offer Space on the terms and conditions as may be specified by Landlord
in the Availability Notice.

44.5 In the event Tenant fails to give a First Offer Exercise Notice in response
to any Availability Notice, Tenant shall have no further rights to receive an
Availability Notice for such Specific Offer Space and Tenant's rights under this
Article 44 shall terminate with respect to such Specific Offer Space and
Landlord shall be free to lease the Specific Offer Space to anyone on any terms
at any time during the Term, without any obligation to provide Tenant with any
further right to lease that Specific Offer Space.

44.6 If Tenant timely and validly gives the First Offer Exercise Notice, then
beginning on the Specific Offer Space Delivery Date and continuing (i) if the
Specific Offer Space Delivery Date is on or before the third (3rd) anniversary
of the Extension Commencement Date, for the balance of the Term (including any
extensions), or (ii) if the Specific Offer Space Delivery Date is after the
third (3rd) anniversary of the Extension Commencement Date, for the Specific
Offer Space Term:

(a) The Specific Offer Space shall be part of the Premises under this Lease (so
that the term "Premises" in this Lease shall refer to the space in the Premises
immediately before the Specific Offer Space Delivery Date plus the Specific
Offer Space).

(b) Tenant's Pro Rata Share of Operating Expenses shall be adjusted to reflect
the increased rentable area of the Premises.

(c) Basic Annual Rent for the Specific Offer Space shall be as specified in the
Availability Notice.

(d) Tenant's lease of the Specific Offer Space shall be on the same terms and
conditions as affect the original Premises from time to time, except as
otherwise provided in this section. Tenant's obligation to pay Rent with respect
to the Specific Offer Space shall begin on the Offer Space Delivery Date. The
Specific Offer Space shall be leased to Tenant in its "as-is" condition and
Landlord shall not be required to construct improvements in, or contribute any
tenant improvement allowance for, the Specific Offer Space. Tenant's
construction of any improvements in the Specific Offer Space shall comply with
the terms of this Lease concerning alterations.

(e) If requested by Landlord, Landlord and Tenant shall confirm in writing the
addition of the Specific Offer Space to the Premises on the terms and conditions
set forth in this section, but Tenant's failure to execute or deliver such
written confirmation shall not affect the enforceability of the First Offer
Exercise Notice.

 

-8-

--------------------------------------------------------------------------------

44.7 Tenant's rights and Landlord's obligations under this Article 44 are
expressly subject to and conditioned upon there not existing a Default by Tenant
under this Lease, either at the time of delivery of the First Offer Exercise
Notice or at the time the Specific Offer Space is to be added to the Premises.

44.8 It is understood and agreed that Tenant's rights under this Article 41 are
personal to Tenant and not transferable except in connection with a Permitted
Assignment. In the event of any assignment of the Lease (other than a Permitted
Assignment) or subletting (other than a Permitted Sublease) of the Premises or
any part thereof, this expansion right shall automatically terminate and shall
thereafter be null and void.

45. Right to Terminate. As used in this Lease, the term "1401 Fourth Amendment"
means the Fourth Amendment to Lease that adds this Section 45 to this Lease.
Provided Tenant is not in Default beyond any applicable cure periods under any
provision of this Lease at the time Tenant exercises its termination right,
Tenant shall have the one-time right to terminate this Lease effective as of
April 30, 2014 (the "Early Termination Date") upon satisfaction of each of the
conditions set forth in this Section 45. Tenant's right to terminate the Lease
under this Section 45 shall not apply to Tenant's lease of any Specific Offer
Space. If Tenant wishes to exercise its right to terminate this Lease, Tenant
must (a) deliver written notice to Landlord by no later than November 30, 2013
(the "Termination Notice Date") of its election to terminate; and (b) pay to
Landlord in good funds on or before the Termination Notice Date the Early
Termination Fee (as defined below). If Tenant exercises its termination right in
accordance with the terms of this Section 45, (a) the Early Termination Date
shall thereafter be deemed the effective termination date for all purposes under
this Lease, (b) any rights of Tenant to expand the Premises or extend the term
of this Lease shall be of no further force or effect and (c) Tenant shall vacate
the Premises prior to the Early Termination Date and shall comply with all terms
of this Lease with respect to the condition of the Premises as of the Expiration
Date and the terms of surrender thereof. As used herein, the term "Early
Termination Fee" means an amount equal to 40% of the sum of (a) $537,491.00 (the
"Commission Amount"), plus (b) the amount of the Basic Allowance (as defined in
the 1401 Fourth Amendment) actually used by Tenant (whether for construction,
rent credits or to pay this Early Termination Fee), plus (c) an amount equal to
4% of the Commission Amount and the Basic Allowance actually used by Tenant. To
the extent the Basic Allowance has not been disbursed under the 1401 Fourth
Amendment, then Tenant may elect by notice to Landlord on or before the
Termination Notice Date to apply the unfunded amount of the Basic Allowance to
payment of the Early Termination Fee under this Section 45. For example, if no
portion of the Basic Allowance has been funded to reimburse Tenant for Tenant's
Work Costs or applied to the payment of Basic Rent, the entire Basic Allowance
may be applied by Tenant to payment of the Early Termination Fee. To the extent
Tenant elects to apply all or any portion of the Basic Allowance to payment of
the Early Termination Fee, (i) Tenant shall have no further right to receive
such portion of the Basic Allowance applied against the Early Termination Fee or
apply the portion of the Basic Allowance applied against the Early Termination
Fee to payment of Basic Rent under the 1401 Fourth Amendment, (ii) the amount of
the remaining Basic Allowance shall be reduced by the amount of the Early
Termination Fee that would have been payable with respect to that remaining
portion had it been applied in full against the Early Termination Fee on the
Termination Notice Date (the amount of the remaining Basic Allowance after that
reduction being referred to as the "Net Remaining Basic Allowance"), and
(iii) Tenant may apply all or any portion of the Net Remaining Basic Allowance
against subsequent Basic Rent under the 1401 Fourth Amendment.

 

-9-

--------------------------------------------------------------------------------

46. Right to Expand. As used in this Lease, (a) the term "1311 Building" means
the building commonly known as 1311 Harbor Bay Parkway, Alameda, California
94502, and (b) the term "Existing 1311 Lease" means that certain Lease Agreement
dated March 27, 2001, as amended by a First Amendment to Lease dated April 12,
2002, a Second Amendment to Lease dated July 16, 2004, and a Third Amendment to

Provided Tenant is not in Default beyond any applicable cure periods under any
provision of this Lease at the time Tenant exercises such option to expand,
Tenant shall have the option to lease the 1311 Building by written notice to
Landlord no later than March 15, 2011. If Tenant timely exercises its right to
lease the 1311 Building as set forth herein, then, within forty-five (45) days
thereafter, Landlord and Tenant shall execute an amendment to the Existing 1311
Lease (the "Expansion Space Amendment"), which Expansion Space Amendment shall
be upon substantially the same terms and conditions as 1401 Fourth Amendment
with the following modifications:

46.1 Defined terms used in the 1401 Fourth Amendment and not specifically
defined in the 1401 Fourth Amendment shall be revised to conform to the

Fourth Amendment, shall not be included in the Expansion Space Amendment

46.4 The right to terminate contained in Article 45, added to this Lease

11. Landlord and Tenant acknowledge that Tenant may desire to make certain
alterations to the Premises in accordance with Article 17 of the Lease
("Tenant's Work"). As part of Tenant’s Work, Tenant shall renovate the restrooms
in the Building with new interior finishes and fixtures comparable to the
recently remodeled bathrooms located upstairs in the 1311 Building. So long as
no monetary Default shall be existing under the Lease (as amended by this
Agreement) as of the date Tenant requests reimbursement of the Allowance (as
defined below), Landlord agrees to reimburse Tenant up to, and not to exceed the
sum of $477,770.00 (the "Basic Allowance") plus $160,000.00 (the "Restroom
Allowance"). (The Basic Allowance and the Restroom Allowance are referred to
herein collectively as, the "Allowance"). Landlord shall pay the Allowance to
Tenant within thirty (30) days after delivery to Landlord of "Tenant's
Completion Notice" (as defined below) according to the terms and conditions of
this Section 11. The Allowance shall be used to reimburse Tenant for hard and/or
soft costs incurred in connection with Tenant's Work ("Tenant's Work Costs");
provided, however, in no event shall the Allowance be used to pay for any of
Tenant's furniture, trade fixtures, equipment or moving costs and in no event
shall the Restroom Allowance be used for any purposes other than renovating the
restrooms in the Building. Upon the completion of Tenant's Work, Tenant shall
submit to Landlord a written notice indicating that Tenant has completed the
construction and performance of Tenant's Work in accordance with the provisions
of Article 17 of the Lease, as amended by this Agreement, which notice shall be
accompanied by all of the following (collectively, "Tenant's Completion
Notice"): (i) copies of paid invoices and a final, unconditional lien waiver
from Tenant's general contractor covering all of Tenant's Work in a form that
complies with applicable laws, showing that full payment has been received for
the construction of Tenant's Work; (ii) if applicable, certification from
Tenant's architect that all of Tenant's Work has been completed substantially in
accordance with the plans and specifications therefor (approved by Landlord, to
the extent Landlord's approval of such plans and specifications was required
under Article 17 of the Lease, as amended by this Agreement) and all local
governmental and quasi-governmental authorities with jurisdiction; and (iii) a
copy of the building permit for Tenant's Work, if applicable, signed by the
appropriate building inspector, indicating that Tenant's Work has been finally
approved. Any portion of the Basic Allowance may be applied by Tenant to the
payment of Basic Rent or to payment of the Early Termination Fee.
Notwithstanding anything to the contrary contained in the Lease as amended, so
long as Tenant has not requested that Landlord supervise the Tenant's Work,
Landlord shall not charge Tenant the five percent (5%) overhead fee provided in
Section 17.9 of the Lease or any fee or other charge for the supervision and/or
overhead associated with the Tenant’s Work. Additionally, notwithstanding
anything to the contrary contained in the Lease, as amended, so long as Tenant
uses a general contractor designated by Landlord or Landlord has otherwise
agreed in writing to waive the requirement for a lien and completion bond in
connection with Landlord's approval of a different general contractor, Tenant
shall have no obligation to provide Landlord with a lien and completion bond in
connection with Tenant’s Work. Landlord hereby approves Rossi as Tenant's
general contractor and agrees that a lien and completion bond will not be
required if Tenant uses Rossi as its general contractor. Landlord further agrees
that prior to Tenant selecting a general contractor, Tenant may inquire of
Landlord as to whether one or more proposed general contractors would be
required to provide a lien and completion bond and Landlord agrees to promptly
respond to that inquiry confirming to Tenant whether or not a particular general
contractor will be required to provide a lien and completion bond.

12. Except as otherwise provided herein, all of the terms and conditions of the
Lease shall continue to apply during the Second Extension Term; provided,
however, that there shall be no rent credit, and that there shall be no
improvement allowance, Landlord construction obligations or other initial
concessions with respect to the Second Extension Term, except as provided in
Section 11 of this Agreement.

13. Landlord hereby represents and warrants to Tenant that it has dealt with no
broker, finder or similar person in connection with this Agreement, and Tenant
hereby represents and warrants to Landlord that it has dealt with no broker,
finder or similar person in connection with this Agreement, other than GVA
Kidder Mathews ("Landlord's Broker") and Peninsula Land & Capital ("Tenant's
Broker"). Landlord and Tenant shall each defend, indemnify and hold the other
harmless with respect to all claims, causes of action, liabilities, losses,
costs and expenses (including without limitation attorneys' fees) arising from a
breach of the foregoing representation and warranty. The commission with respect
to this Agreement shall be paid to Landlord's Broker by Landlord pursuant to a
separate agreement. Landlord will cause Tenant’s Broker to be paid a commission
pursuant to a separate agreement.

14. As additional consideration for this Agreement, Tenant hereby certifies
that:

construction of tenant improvements in the Premises and payment of Tenant
improvement allowances have been satisfied, except those provided for in
Section 11 of this Agreement.

(e) To Tenant's knowledge, there are no existing offsets or defenses which
Tenant has against the enforcement of the Lease (as amended hereby) by Landlord.

15. Except as specifically provided herein, the terms and conditions of the
Lease as amended hereby are confirmed and continue in full force and effect.
This Agreement shall be binding on the heirs, administrators, successors and
assigns (as the case may be) of the parties hereto. This Agreement and the
attached exhibits, which are hereby incorporated into and made a part of this
Agreement, set forth the entire agreement between the parties with respect to
the matters set forth herein. There have been no additional oral or written
representations or agreements. Under no circumstances shall Tenant be entitled
to any Rent abatement, improvement allowance, leasehold improvements, or other
work to the Premises, or any similar economic incentives that may have been
provided to Tenant in connection with entering into the Lease, unless
specifically set forth in this Agreement. In the case of any inconsistency
between the provisions of the Lease and this Agreement, the provisions of this
Agreement shall govern and control. Landlord and Tenant shall not be bound by
this Agreement until both Landlord and Tenant have executed and delivered the
same to the other. Time is of the essence of this Agreement and the provisions
contained herein.

16. Effective as of the date hereof, all references to the "Lease" shall refer
to the Lease, as amended by this Agreement.

17. As an inducement to Landlord to enter into this Lease Agreement, Tenant
hereby represents and warrants that: Tenant is not named on any list issued by
the Office of Foreign Assets Control of the United States Department of the
Treasury ("OFAC") pursuant to Executive Order 13224 or any similar list or any
law, order, rule or regulation or any Executive Order of the President of the
United States as a terrorist, "Specially Designated National and Blocked Person"
or other banned or blocked person (any such person, group, entity or nation
being hereinafter referred to as a "Prohibited Person"). Tenant and Landlord
covenant and agree to comply with all requirements of law relating to money
laundering, anti-terrorism, trade embargos and economic sanctions, now or
hereafter in effect.

18. Tenant represents and warrants to the best of its knowledge after due
inquiry that at the time this Agreement is entered into, neither Tenant nor its
affiliates (within the meaning of part V(c) of Department of Labor Prohibited
Transaction Class Exemption 84-14 (“PTE 84-14”), as amended) has the authority
to appoint or terminate The Prudential Insurance Company of America
(“Prudential”) as an investment manager to any assets of Prudential's insurance
company separate account Western Conference of Teamsters ("WCOT"), nor the
authority to negotiate the terms of any management agreement between Prudential
and WCOT.

19. Landlord and Tenant hereby acknowledge and agree that it is not a purpose of
the Lease or any of the transactions contemplated herein to exert influence in
any manner over the reason or judgment of any party with respect to the referral
of patients or business of any nature whatsoever. Landlord and Tenant hereby
agree that the terms of this Agreement have been negotiated and determined at
arm's length, as such terms would be negotiated and determined by unrelated
parties and do not take into account the volume or value of referrals or
business that may otherwise be generated between the parties for which payment
may be made in whole or in part under Medicare, Medicaid or other Federal health
care programs.

20. Landlord and Tenant hereby agree that the Existing 1311 Lease (as defined in
