installs the Antenna and is operating within the technical parameters specified
by its manufacturer and any governmental license. If Lessee should cause such
measurable interference, Lessee shall, at its expense, eliminate it within five
(5) days after notice thereof (and the grace periods in Section 6 below will not
apply with respect thereto, and Lessee shall in any event indemnify, defend, and

modifications to limit any interference to or from other equipment or
communications facilities that Lessor wishes to permit to be installed. Lessor
shall have no liability to Lessee for any interference of any kind to the
Antenna and/or the use and operation thereof, including, without limitation,
interference caused by (i) any other equipment located in, on or around the

related to the placement of the Antenna on the Building. If Lessor determines
that the Antenna is not being maintained in the condition required by this
Agreement as herein provided, and without limiting Lessor's other rights and
remedies under this Agreement, Lessor shall have the right, if Lessee fails to
remedy the condition(s) identified by Lessor to the reasonable satisfaction of

Agreement. Lessee shall pay to Lessor, on demand, Lessor's reasonable costs and
expenses incurred pursuant to this paragraph.

and (ii) with respect to non-monetary defaults, except for the default to be
cured within five (5) days as provided in Section 3 above, if Lessee does not
promptly commence the cure thereof following written notice and the same is not
cured within thirty (30) days of receipt (or evidence of attempted delivery) of
written notice by Lessee of said default; provided, however, the occurrence of
any interruption in, or disconnection of any telecommunications services of any
tenant in the Building caused by the act or omission of Lessee or any employee,
contractor or agent of Lessee while performing any work in or about the Antenna
or any of the Raceways, which is not corrected within 24 hours after such
occurrence,

the Equipment License granted herein.

     6.2 Default by Lessor. Lessee may pursue all rights and remedies available
at law or in equity following any breach or default by Lessor under this
Agreement if Lessor does not cure the same within thirty (30) days after receipt

or such additional period of time as may be reasonably necessary under the
circumstance for Lessor to diligently cure such default. In any event, Lessor's
liability under this Agreement shall be limited in the same manner and to the
same extent as set forth in Section 30.4 of the Lease.

7. Casualty. No casualty affecting the use of the License Area, or any damage
to, or loss of the Antenna, the Conduit, and related cable, wiring, and
equipment resulting from any casualty, shall entitle Lessee to any claim or
right to terminate the Lease, or serve as a basis for any claim of constructive
eviction. Lessor shall have no obligation to restore or replace the Antenna, the
Conduit, and related cable, wiring, and equipment following any casualty to the
Building, and Lessor's sole obligation following any casualty shall be to
restore the License Area consistent with, and according to, such a timetable as
Lessor otherwise adopts for repairs to and restoration of the Building following
such a casualty.

all cabling, wiring and any related facilities, and return the Building to the
condition in which it existed prior to the installation of the Antenna, at its
sole cost and expense, prior to the expiration or any termination of this
Agreement. Lessee's obligation hereunder shall survive the termination of this
Agreement and the Lease.

9. Personal Right. The rights granted to Lessee under this Agreement are
personal to the named Lessee under the Lease in connection with the occupancy of
the Premises, and shall not be assignable or transferable to any other person
(including any assignee or subtenant) claiming by or through Lessee, without the
prior written consent of Lessor, except for an assignee or subtenant permitted
by, or approved by Lessor in accordance with, Section 20 of the Lease.

10. Notices. Any and all notices given or required under the terms of this
Agreement shall be given in the manner provided in the Lease, and shall be
deemed effective as of the date therein provided.

11. Disclaimer of Liability. Notwithstanding any other provision in this
Agreement, Lessee agrees that the installation, operation, existence, use,
removal, maintenance, repair, and/or replacement of the Antenna, the Conduit,
and all cabling, wiring, and related facilities shall be at Lessee's sole cost
and risk. Lessee hereby waives and releases Lessor and its members, and the
respective past or present employees, directors, and officers thereof from and
against, all claims for damage to, or loss of any property or injury, illness,
or death of or to any person in, upon, or about the Building or the Hayden Ferry
Lakeside project arising from the installation, operation, existence, use,
removal, maintenance, repair, and/or replacement of, or access to, any of the

                               Exhibit F - Page 6

<PAGE>

Antenna, the Conduit, or any cabling, wiring, or related facilities arising or
caused in any manner (including, without limitation, as a result of the act,
omission, or active or passive negligence of Lessor or its members, or the
respective past or present employees, directors, or officers thereof), other

Lessor, its employees, agents, or contractors. In addition, Lessor's approval of
any plans or specifications under this Agreement with respect to the Antenna,
the Conduit, and/or any cabling, wiring, or related facilities, shall not
constitute any representation or warranty of any kind by Lessor that such plans
and specifications are in compliance with applicable laws and regulations,
and/or will prevent interference with the operation of similar facilities by
other tenants.

12. Miscellaneous.

          12.1 Lessee acknowledges and agrees that the rights granted it under
this Agreement are contract rights and not an estate or interest in land or real
property. Lessee shall not record or file this Agreement in any public records
(including, without limitation, recording a memorandum of this Agreement).

other for any consequential or punitive damages arising from a default or breach
of its obligations under this Agreement.

          12.3 Failure by a party to enforce its rights under this Agreement
shall not be deemed a waiver of such rights or any other rights, nor shall the
waiver by either party of a breach of any provision of this Agreement be deemed
to be a waiver of any subsequent breach of the same or any other provision of
this Agreement.

of the Lease incorporated herein by reference embody the entire agreement
between the parties regarding the subject matter hereof and supersede any and
all prior negotiations, expressions of intent, representations, or agreements

                            ADDENDUM TO OFFICE LEASE
                                       FOR
                           HAYDEN FERRY LAKESIDE, LLC
                                     PHASE I

     THIS ADDENDUM shall supplement and modify the Office Lease between Hayden
Ferry Lakeside, LLC, as Lessor, and MEDAIRE, INCORPORATED, an Arizona
corporation, as Lessee:

A. The following shall be added as Section 1.5 of the Lease:

     1.5 First Right to Lease Certain Space on 6`h Floor. During the Lease Term,
Lessee shall have the first right to lease certain space on 6`h floor of the
Building and designated "option space" on Exhibit A attached hereto containing
approximately 9,076 square feet of Rentable Area (hereafter referred to as the
"Option Space"), but Lessee shall have such right only to the extent
specifically provided for in this Section:

          1.5.1 After the date of this Lease and until Lessee's rights hereunder
expire as set forth below, Lessor shall not lease any or all of the Option Space
unless it has first signed a non-binding letter of intent with a prospective
tenant ("Offer") and first complies with the following provisions:

               1.5.1.1 Upon receipt of an Offer, then Lessor shall, prior to
negotiating a lease for the Option Space covered by the Offer, first submit a
written notice to Lessee that Lessor intends to proceed with negotiations, which
notice shall specify the Rentable Area of such portion of the Option Space,
provided that the Rentable Area shall be designated by Lessor utilizing a
reasonable load factor and other considerations used by Lessor, pursuant to
Section 1.2, to establish the Rentable Area of the original Premises.

               1.5.1.2 Upon receipt of such notice from Lessor, Lessee shall
have five (5) business days thereafter ("Acceptance Period") to provide written
notice to Lessor that Lessee elects to incorporate such portion of the Option
Space into the Premises ("Lessee's Acceptance of Option Space"), in which event
Lessor and Lessee shall be bound by the election of Lessee to include the Option
Space within the Premises, and the Option Space shall be subject to all the
terms and conditions of this Lease, including the Base Rental per square foot
set forth in the Basic Lease Information.

               1.5.1.3 The foregoing notwithstanding, this Section shall
constitute a one time opportunity for Lessee with respect to each portion of the
Option Space covered by an Offer. For example, if the first Offer covers 1,000
square feet of Rentable Area and Lessee fails

                                Addendum - Page 1

<PAGE>

to deliver Lessee's Acceptance of Option Space to Lessor within the Acceptance
Period, Lessor shall thereafter be entitled to lease all or a portion of such
1,000 square feet of the Option Space to the prospective tenant referred to in
the Offer. However, if Lessor does not thereafter enter into a binding lease
pursuant to such Offer, then such 1,000 square feet will again be part of the
Option Space and if a new Offer is received from another tenant covering such
1,000 square feet, such new Offer will be subject to the rights of Lessee under
this Section until an Offer covering all or each portion of the Option Space
results in a binding lease therefore.

          1.5.2 Upon Lessor's receipt of Lessee's Acceptance of Option Space
pursuant to Section 1.5.2.2 then: (a) the Base Rental for the Option Space
covered by Lessee's Acceptance of Option Space shall be calculated based on the
Rentable Area thereof specified in Lessor's notice to Lessee pursuant to Section
1.5.1.1, and the applicable rent per square foot per year of Rentable Area as
set forth in the Basic Lease Information for the Premises, (b) the tenant
improvements to be installed by Lessor for the Option Space shall be constructed
in accordance with Exhibit C attached hereto, provided that (i) the amount per
square foot set forth in the Basic lease Information for Tenant Improvement
Allowance shall be multiplied by the usable area of the Option Space designated
by Lessor in its notice given to Lessee pursuant to Section 1.5.1.1 and such
tenant improvements shall be installed pursuant to a construction schedule
determined by Lessor and Lessee acting reasonably and in good faith, and (c)
Lessee shall be obligated to pay Base Rental on such Option Space within fifteen
(15) days after Lessor substantially completes such. tenant improvements and
tenders possession of such Option Space to Lessee, or when Lessee opens for
business in the Option Space, whichever is first to occur.

          1.5.3 If Lessee's Acceptance of Option Space is properly delivered to
Lessor in accordance with this Section 1.5, then Lessor and Lessee shall, acting
reasonably and in good faith, within fifteen (15) days thereafter, execute and
deliver an amendment to this Lease which makes the Option Space covered by the
Offer part of the Premises, incorporates the Base Rental for such Option Space,
and incorporates other applicable terms for the Option Space, and Lessor's
construction schedule established as herein provided.

          1.5.4 It Lessee's Acceptance of Option Space is not properly and
timely delivered after receipt of Lessor's notice pursuant to Sections 1.5.1.1,
Lessee shall thereafter have no further rights to any of the Option Space
described in the Offer if a binding lease is executed thereafter pursuant to
such Offer. Otherwise, the second sentence of Section 1.5.1.3 shall apply with
respect thereto.

          1.5.5 The foregoing notwithstanding, (a) Lessee's rights provided for
in this Section shall become null and void if Lessee is in default under this
Lease and applicable grace periods set forth in Article 29 have expired, and (b)
all rights under this Section shall terminate upon the first to occur of (i) the
expiration or earlier termination of this Lease, or (ii) Lessor's election to
re-enter the Premises after Lessee's default as provided in Article 29.

B. The portion of the Basic Lease Information entitled "TERM" is hereby amended
to add the following below "Termination Date":

     Options: two (2) option periods of five (5) years each.

C. The portion of the Basic Lease Information entitled "PARKING SPACES AND
PARKING RENTAL" is hereby amended by deleting each reference therein to "Lease
Term" and replacing the same with "Initial Term". In addition, during each
Renewal Option period which Lessee may elect to exercise pursuant to Section
2.1.2, the rental to be paid for the Parking Spaces to which Lessee is entitled
under this portion of the Lease (10 executive parking spaces, and 65 unreserved
parking spaces) shall be equal to 90% of the rent being offered to prospective
tenants or customers, as the case may be, by the respective Parking Facility
Owner at the time Lessee exercises the Renewal Option pursuant to Section 2.1.2,
and said rental rate so established for each type of Parking Space shall remain
fixed throughout the Renewal Option period, unless adjusted in the same manner
for the second Renewal Option period, if exercised by Lessee.

D. Section 2.1 of the Lease is hereby deleted and replaced with the following:

2.1 Lease Term.

     2.1.1 Initial Term. Except as provided herein, the initial term of this
Lease shall be for the period set forth in the Basic Lease Information from the.
Commencement Date to the Termination Date ("Initial Term").

     2.1.2 Extension of Initial Term. Lessee shall have the right and option to
extend the Initial Term of this Lease and the Termination Date for the option
periods set forth in the Basic Lease Information (each referred to herein as a
"Renewal Option") upon all of the terms, covenants, and conditions set forth in
this Lease, except that Base Rental and the Expense Stop shall be established as
set forth in Section 3.6 below. Each Renewal Option may be exercised only if (i)
Lessee expressly and unconditionally exercises such option by providing written
notice thereof to Lessor no less than six (6) months and no more than nine (9)
months prior to the expiration of the Initial Term, and (ii) Lessee is not in
default under this Lease at the time of the exercise of the option rights set
forth herein and/or at the time a Renewal Option period is to commence. If
Lessee does not satisfy the requirements of subsections (i) and (ii), the option
rights set forth in this Section shall automatically be deemed waived.

     2.1.3 "Lease Term" Defined For purposes of this Lease, Lease Term shall
refer to the Initial Term, as may be extended pursuant to Section 2.1.2.

E. The following shall be added as Section 3.6 of the Lease:

     to the sale of any real property for and/or the development of the P-1
Parking Structure and/or the Underground Parking Facilities, Lessor shall
provide notice to any prospective Parking Facility Owner of the terms and
conditions of this Lease.

3.6 Determination of Base Rental for Renewal Options. If Lessee properly
exercises its right with respect to a Renewal Option as provided in Section
2.1.2, then the Base Rental due and payable for the Premises during the Renewal
Option period shall be the Fair Market Rental Rate per rentable square foot
determined as hereafter provided:

     3.6.1 Within forty-five (45) days after Lessee timely exercises its option
rights as herein provided, Lessor shall submit to Lessee in writing Lessor's
proposed base rental and expense stop for the Premises, and any economic
benefits Lessor may elect to provide to Lessee, in Lessor's sole discretion,
such as a Tenant Improvement Allowance to refurbish or upgrade the Premises
("Lessor's Economic Terms for the Premises").

     3.6.2 If Lessee does not submit its written objection to Lessor's Economic
Terms for the Premises within thirty (30) days after receipt thereof then the
Base Rental and Expense Stop included therein shall constitute the "Fair Market
Rental Rate" for purposes of this Section, provided that all other terms
constituting Lessor's Economic Terms for the Premises shall also apply. If
Lessee delivers its written objection to Lessor's Economic Terms for the
Premises within said 30-day period, then the Fair Market Rental Rate shall be
established pursuant to Section 3.5.3 below, provided that Lessor's Economic
Terms for the Premises (excluding Lessor's proposed base rental) shall be used
to determine the same as therein provided.

     3.6.3 If Lessor and Lessee cannot agree upon the Fair Market Rental Rate
pursuant to Section 3.5.2 above within the time period set forth therein for
Lessee's acceptance or rejection of Lessor's proposed Fair Market Rental Rate
("Rent Determination Period"), then the Fair Market Rental Rate shall be
established as follows:

          3.6.3.1 Within fifteen (15) days after the expiration of the Rent
Determination Period, Lessor and Lessee shall each appoint a qualified,
independent MAI appraiser of its choice with at least five (5) years of
experience in appraising prevailing market rates for properties similar to the
Building ("Qualified Appraiser"). The two appraisers selected by Lessor and
Lessee shall then appoint a third Qualified Appraiser, and the third Qualified
Appraiser shall constitute the "Appraiser" for purposes of this Section. If
either party fails to appoint a Qualified Appraiser within said 15-day period,
then the Qualified Appraiser timely appointed by the other party shall
constitute the "Appraiser" for purposes of this Section.

          3.6.3.2 Lessor and Lessee shall direct the Appraiser to make an
independent determination of the prevailing market rate base rental and expense
stop for the Premises based on Lessor's Economic Terms for the Premises, and
based on the quality of the space, existing improvements and amenities, and the
then prevailing market rate per square foot of rentable area and expense stop
for office space comparable to the Premises and the Building in quality,
appearance, and design in the Phoenix metropolitan area, and such other
standards as may be customarily utilized by MAI appraisers. The Appraiser shall
be required to submit its determination within forty-five (45) days after the
Rent Determination Period, and the same shall constitute the Fair Market Rental
Rate to be used for purposes of this Section.

                                Addendum - Page 4

<PAGE>

          3.6.3.3 If the Fair Market Rental Rate established pursuant to this
Section 3.5.3 is equal to or greater than the base rental per square foot and
expense stop offered by Lessor in Lessor's Economic Terms for the Premises, then
Lessee shall bear the full expense of the Appraiser. If the Fair Market Rental
Rate determined pursuant to this Section 3.5.3 is less than the base rental and
expense stop so established by Lessor, then Lessor shall bear the full expense
of the Appraiser.

     3.6.4 When the Fair Market Rental Rate is established as set forth above,
Lessor and Lessee shall, acting reasonably and in good faith, within thirty (30)
days thereafter, execute and deliver an amendment to this Lease, which
acknowledges the extension of the Lease Term, establishes the Base Rental using
the Fair Market Rental Rate, and establishes the rental for the Parking Spaces
allocated to Lessee as provided in the Basic Lease Information.

     3.6.5 Any other provision in this Section notwithstanding, in no event
shall the Base Rental to be paid for the Premises during any Renewal Option be
less than the Base Rental applicable to the Initial Term or any preceding
Renewal Option, as the case may be, after adjustments for changes in the Expense
Stop, if any.

F. Lessor acknowledges that Lessee desires to install two satellite dishes on
the roof of the Premises for benefit of its business operations in the Premises,
and for no other purpose. In connection therewith, Lessee and Lessor agree to
execute, simultaneously with the execution of this Lease, a Rooftop License
Agreement in the form attached to this Lease as Exhibit F.

     NOW THEREFORE, in consideration of the mutual covenants set forth herein,

     2. Lessee's Right to Provide Own Janitorial Service. Lessor and Lessee
hereby agree that, notwithstanding any provisions to the contrary in Articles 4
and 8 in the Lease, commencing April 1, 2004, Lessor shall discontinue
janitorial service for the interior of the Premises, and Lessee shall provide
its own janitorial services within the Premises (but not outside the Premises),
so long as Lessee complies with the following requirements (referred to herein
as the "Performance Standards"):

          2.1 the level of janitorial service provided by Lessee shall be
appropriate for a class A office development such as Hayden Ferry Lakeside and
shall in any event equal or exceed the level of janitorial service provided by

activity, work, and other acts or omissions of such janitorial company, its
agents, employees or contractors; and

Premises, Lessee shall cause said company to comply with Lessor's requirements
for independent contractors, including the insurance requirements set forth on
Schedule 1 attached to this Second Amendment; and

          2.4 in no event shall Lessee, nor any janitorial company engaged by
Lessee, be entitled to use any facilities within the Building outside of the
Premises to provide such janitorial service, including, without limitation, any
janitor closets, utility rooms, or restrooms outside of the Premises; and

          2.5 Lessee shall advise its janitorial company that Lessee's situation
with respect to the cleaning of its Premises is unique within the Building, and

non-business hours designated by Lessor from time to time to avoid disturbing
other tenants and to preserve the professional image of the Project.

until the date on which Lessee no longer provides its own janitorial service in
compliance with the Performance Standards, the following shall apply:

against monthly installments of Base Rent otherwise due under the Lease in an
amount equal to $672.33 per month (14,407 usable square feet times $.56 per
square foot divided by 12) if the Performance Standards were met during the
previous month; and

          3.2 the "Expense Stop" set forth in the Basic Lease Information in the
Lease shall be reduced from $6.00 to $5.44 (i.e., a reduction of $.56).

     4. Inspection of Premises. Lessor shall have the right to inspect the
Premises from time to time to ensure that the Performance Standards are being
met.

     5. Lease Otherwise Unchanged. Except as otherwise set forth in this
