                                     PARTIES

         This contract ("Agreement") is made this ____ day of ________, 2003,
between YUKON-KUSKOKWIM HEALTH CORPORATION ("YKHC"), a non-profit Alaska
corporation with its principal offices at P.O. Box 528, Bethel, Alaska 99559,
and AMERICAN AIR NETWORK, INC. ("Carrier"), a Missouri corporation with its
principal offices at 657 North Bell Avenue, Suite 200, Chesterfield, Missouri
63005.

                                    RECITALS

         WHEREAS, YKHC is a tribal consortium of 58 federally recognized tribes
that contracts with the federal government pursuant to the Indian
Self-Determination and Education Assistance Act, 25 U.S.C. 450, et seq., to
provide health care and related services to Alaska Natives;

         WHEREAS, YKHC's mission is, among other things, to achieve the greatest
possible improvements in the health status of the people of the Yukon-Kuskokwim
Delta region, and YKHC is fully committed to the development of culturally
relevant programs for primary care, prevention, and health promotion in a
setting that fosters health care delivery in conjunction with Alaska Native
Self-Determination;

         WHEREAS, Carrier specializes in providing air ambulance aircraft,
flight and maintenance personnel and related aviation services;

         WHEREAS, the parties wish to enter into a contract whereby Carrier will
provide air ambulance services, crew quarters and storage space.

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
contained herein, the parties agree as follows:

1.       TERM

         The term of this Agreement shall be five (5) years, beginning at 12:00
noon on September 29, 2003 ("Effective Date") and ending September 29, 2008.
Thereafter, this Agreement shall continue in full force and effect on a

2.       SCOPE OF WORK

         A.       CARRIER

                  2.1 AVIATION EQUIPMENT, PERSONNEL, FACILITIES, AND FINAL
AUTHORITY FOR FLIGHT SAFETY. Carrier shall provide to YKHC at least two (2)
fully operational and dedicated aircraft from the aircraft listed in EXHIBIT A
to this Agreement for use by YKHC as a critical care air ambulance, the backup
aircraft, equipment and pilots specified in EXHIBIT A to this Agreement, and the
facility set forth in EXHIBIT B. Carrier shall also supply all maintenance and
other support services required to meet the Mission Readiness requirements of
this Agreement. Carrier's aircraft and personnel shall meet all FAA and State of
Alaska requirements for commercial air ambulance services, and Carrier shall in
all other ways be responsible for complying with all applicable laws. Carrier
shall retain final authority on all matters concerning flight safety, flight
operations and aircraft maintenance.

                  2.2 MISSION READINESS. Carrier shall maintain at least two (2)
of the aircraft identified in EXHIBIT A and a crew for that aircraft in a state
of Mission Readiness for critical care air ambulance services. "Mission
Readiness" means that Carrier's aircraft and pilots shall be "wheels up" 24
hours per day, 7 days per week, 365 days per year, within 45 minutes of receipt
of a written or oral dispatch from YKHC. Carrier's duty to be wheels up within
45 minutes is subject only to factors beyond Carrier's reasonable control (such
as weather or Acts of God, etc.), and the timely response of YKHC's on-board
medical crew. Any failure by Carrier to meet this level of Mission Readiness
shall make Carrier liable for the remedies provided herein in Sections 18 and
19. This provision shall apply only to dispatches to destinations in the United
States, and shall not apply to dispatches to destinations outside of the United
States.

                  2.3 SUBSTITUTION OF AIRCRAFT. It is expected that Carrier will
use the aircraft set forth in EXHIBIT A for all flights, but that Carrier will
have the right to substitute equivalent aircraft meeting all the applicable
requirements of this Agreement, including Exhibit A, except for the requirement
that the aircraft be painted in the Aero Med paint scheme. If at any time
Carrier desires to use such substitute aircraft, Carrier's representative shall
inform YKHC's Director of Flight Services or his/her designee, which consent
YKHC shall not unreasonably withhold. If Carrier utilizes one or more substitute
aircraft for more than 30 days, the substitute aircraft shall be painted in the
Aero Med paint scheme.

                  2.4 SUPPLEMENTAL AIRCRAFT. Carrier may, but is not required
to, provide supplemental aircraft to YKHC, in accordance with the rate structure
stated in EXHIBIT A hereto. "Supplemental Aircraft" is defined as aircraft
requested by YKHC to provide a third or subsequent critical air ambulance flight
after dispatch of the two (2) dedicated aircraft required by Sections 2.1 and
2.2 of this Agreement. Carrier's inability or failure to provide such
supplemental aircraft or the failure of that aircraft to meet the Mission
Readiness requirement shall not be deemed a breach of this Agreement or entitle
YKHC to any of the remedies set forth in Sections 18 and 19 of this Agreement.

AIR AMBULANCE SERVICES AGREEMENT                                    Page 2 of 13

<PAGE>

                  2.5 ALASKA NATIVE TRIBAL HEALTH CONSORTIUM (ANTHC) CONTRACT
REQUIREMENTS. Carrier acknowledges that it is to the parties' mutual benefit
that YKHC continue to hold the ANTHC contract for medevac services. In the event
YKHC is awarded additional missions or an expanded scope of work under the ANTHC
contract, Carrier shall provide such additional aviation equipment, aircraft and
crew or other additional equipment or services required by the ANTHC contract,
which requirements shall automatically be incorporated into this Agreement at
rates and such other terms as are mutually agreeable to YKHC and Carrier, and as
established in a written supplement to EXHIBIT A signed by both parties.

                  2.6 DISCLOSURE TO YKHC. Carrier shall inform YKHC's on-board
medical crew as soon as reasonably practicable of any concerns the pilot may
have about the possibility of being unable to safely complete all phases of each
flight. Carrier's duty to provide such disclosure shall exist during all phases
of any mission, including prior to departure and while en route.

         B.       YKHC

                  2.7 MEDICAL EQUIPMENT AND PERSONNEL, AND FINAL AUTHORITY FOR
MEDICAL ISSUES. YKHC shall provide all on-board medical crew for patient
transports, and, except as allocated to Carrier in EXHIBIT A, YKHC shall provide
all medical equipment for such flights. YKHC shall retain final authority on all
matters concerning the medical care provided to the air ambulance patients.

                  2.8 DISPATCH. YKHC shall provide a communications center for
coordination of flight missions and medical flight communications. YKHC has sole
discretion to designate any and all on-board medical crew, patients and other
passengers to be carried on the flights. Carrier and its flight crews shall
accept all such individuals designated by YKHC, including patients with
communicable diseases, unless the presence of such person on the aircraft would
directly and adversely affect flight safety. As used in this Agreement,
"dispatch" shall mean only YKHC's requesting of a flight and the identification
of the medical crews, passengers and destinations, and shall in no way assume
the meaning "dispatch" may have in the Federal Aviation Regulations, it being
the intent that Carrier at all times remains in operational control of all
aviation aspects of the flights.

                  2.9 CLASSIFICATION OF PATIENTS FOR TRANSPORT. YKHC shall be
responsible for correctly classifying all patients under the laws and
regulations regulating critical care transport.

3.       PAYMENTS

                  3.1 COMPENSATION. As total compensation for the services
provided by Carrier pursuant to this Agreement, YKHC shall pay Carrier the
amounts specified in EXHIBIT A for flight hours and reimbursable expenses.
"Flight hours" are defined as the time the aircraft begins to move under its own
power, and ends at the time the aircraft stops moving under its own power.
"Reimbursable expenses" are defined as only those expressly set forth in EXHIBIT
A. Except as specifically allocated to YKHC in EXHIBIT A, costs incurred by
Carrier in any of its operations are not chargeable to YKHC. Carrier shall
submit monthly invoices to YKHC's Director of Aeromed International, 4700
Business Park Blvd., Building E, Suite 25, Anchorage, Alaska 99503, as provided
in Exhibit A, and YKHC shall pay Carrier's invoices as provided in Exhibit A.
Any disputed portions of any invoices or payments shall follow the procedure set
forth in Sections 18.5 and 18.6 of this Agreement and the undisputed portions of
the invoices shall be paid pursuant to the provisions of Section 2 of Exhibit A.

                  3.2 CANCELLED OR INCOMPLETE FLIGHTS. Carrier shall be
compensated for actual flight hours flown as a result of a written or oral
dispatch from YKHC for flights terminated or not completed due to weather and
flights that are cancelled by YKHC after dispatch. Such flights shall be
invoiced and paid at the rates specified in EXHIBIT A. Carrier shall not,
however, be entitled to compensation for any flight terminated or not completed
due to aircraft mechanical problems or other problems attributable to Carrier,
and if such flight has already departed but thereafter is not completed, the
penalty provisions of Section 18 shall be assessed against Carrier. Carrier
shall be responsible for ensuring that its flight crews comply with all FAA
duty/rest time requirements, and that flight crews have sufficient duty time
available to complete a dispatch, including any diversions or delays that may
reasonably be anticipated. Carrier shall, as part of each pre-flight briefing,
disclose to YKHC each flight crew member's duty/rest status. If thereafter,
during an already dispatched flight, Carrier's flight crew encounters
unreasonably lengthy delays that cause Carrier's flight crew to exceed
applicable FAA duty/rest time regulations and thus cause Carrier's flight crew
to terminate the flight, and if such delays are caused by YKHC's actions or
inactions or unforecasted weather, Carrier shall be entitled to compensation
from YKHC for the flight hours actually flown during that flight, even if the
flight is terminated before completion, and YKHC shall pay that invoice at the
rates specified in Exhibit A.

                  3.3 MODIFICATION OF RATES. During the term of this Agreement
or any extension thereof, the rates specified in EXHIBIT A shall not be changed
except by mutual written agreement signed by both parties.

4.       OPERATIONS REVIEW GROUP

         The parties acknowledge that open, prompt and continuing communications
between YKHC and Carrier are desired. Accordingly, the parties shall create an
Operations Review Group to discuss and resolve safety and compliance issues that
may arise as a result of this Agreement. Carrier and YKHC shall each appoint

AIR AMBULANCE SERVICES AGREEMENT                                    Page 4 of 13

<PAGE>

three representatives from their respective organizations to participate in the
meetings. YKHC's Director of Flight Services shall be a member and the chair of
the Operations Review Group. Carrier's representatives shall include a
management representative, a medevac pilot-in-command, and a chief mechanic. The
Operations Review Group shall meet bi-weekly or at such other times as the
Operations Review Group shall specify. Members may participate telephonically.

5.       FLIGHT PRE- AND POST-BRIEFINGS

         In addition to the bi-weekly Operations Review Group meetings, before
each flight Carrier's flight crew shall openly discuss with YKHC's on-board
medical crew the safety and anticipated conditions of the dispatch and flight.
This information shall include, at a minimum, runway conditions, and current and
forecasted weather at all takeoff and landing locations and the en-route course,
and the flight crew's duty/rest status. After each medevac mission Carrier's
flight crew and YKHC's on-board medical crew shall also meet to discuss the
mission and any concerns or issues that affected the safety or performance of
the mission. Carrier and YKHC are jointly responsible for ensuring that such
meetings occur.

6.       AVOIDANCE OF EXCESSIVE PERSONNEL TURNOVER

         Carrier acknowledges that stable pilot and mechanic staffing is
important to safe, successful operations, and Carrier agrees to make reasonable
efforts to minimize pilot and mechanic turnover. In the event YKHC at any time
becomes concerned about such turnover, YKHC may by written request to Carrier
ask Carrier to provide, within 48 hours, an oral or written response to the
request. Should YKHC thereafter believe that further action is needed, YKHC may
make a written request for Carrier to submit a written plan of improvement, and
Carrier shall provide this written plan within two (2) weeks. Carrier's failure
to respond to YKHC's request or failure to cure the staffing problems within two
(2) months of YKHC's request shall constitute cause for termination.

7.       EXCLUSIVITY

                  7.1 CARRIER. Carrier shall provide aviation medevac services
exclusively to YKHC within the State of Alaska. Neither Carrier nor Carrier's
parent companies, subsidiaries, affiliated companies, employees or other
representatives may fly any medevac mission or provide related aviation services
for itself or for any other person or entity within Alaska without YKHC's prior
written consent, and YKHC may withhold such consent with or without cause in
YKHC's absolute and sole discretion.

                  7.2 YKHC. With the exception of YKHC's current or future YK
Delta village-to-Bethel operations, YKHC shall exclusively use Carrier for all
critical care air ambulance services operated by YKHC, except to the extent that
YKHC exercises its discretion to hire replacement carriers under Section 18.1 of
this Agreement or YKHC's needs exceed Carrier's ability or desire to supply

AIR AMBULANCE SERVICES AGREEMENT                                    Page 5 of 13

<PAGE>

additional aircraft pursuant to Section 2.4. For purposes of this paragraph,
"operated by YKHC" means flights made pursuant to any critical care or medevac
license held by YKHC during the term of this Agreement, whether under the name
"Aeromed International" or otherwise. Should YKHC require additional aircraft
pursuant to this Agreement, YKHC shall notify Carrier of such needs and YKHC may
exercise its rights to utilize other carriers only if Carrier advises YKHC
within a reasonable time that Carrier is unable to provide the requested
additional aircraft.

8.       MARKETING

         YKHC and Carrier agree to engage in joint marketing activities suitable
for promoting YKHC's medevac services, as determined from time-to-time by the
parties. Except to the extent such particular marketing agreements specifically
provide otherwise, each party shall bear the marketing costs incurred by that
party.

9.       PERMITS AND CERTIFICATIONS

         Carrier shall be responsible for obtaining and maintaining in good
standing all applicable permits, professional and business licenses and other
certifications for Carrier and Carrier's personnel, aircraft, equipment and
subcontractors related to the services provided pursuant to this Agreement.

1O.      DEBARMENT

         Carrier certifies that, to the best of its knowledge, Carrier, its
employees and subcontractors are not currently and never have been debarred or
suspended by any governmental and/or tribal body.

         A.       CARRIER'S INSURANCE

         Carrier shall maintain, at its expense, the following minimum insurance
coverage with insurance companies satisfactory to YKHC, and Carrier shall name
YKHC as an additional named insured on the policies listed. Carrier shall
promptly notify YKHC of any change or lapse in coverage. By no later than the
effective date of this Agreement, on each six-month anniversary thereafter, and
as otherwise requested by YKHC, Carrier shall provide to YKHC certificates
signifying the following coverage:

                  11.1     All risk ground and flight aircraft hull insurance;

                  11.2 Aircraft liability insurance covering injuries to

arising out of any one event, or the minimum amount required at any time by the
Federal Aviation Regulations or other laws or the ANTHC contract, whichever
amount is greater;

         YKHC shall maintain, at its expense, the following minimum insurance
coverage:

minimum policy limit of One Million Dollars ($1,000,000) per occurrence and

minimum amounts required by Alaska law.

12.      RECORDS

         Carrier shall cause to be created, and shall thereafter maintain for a
period of at least five (5) years, all records required by law, and Carrier
shall be responsible for causing its subcontractors, if any, to similarly create
and maintain all such records. This duty to maintain records shall continue for
five (5) years after the termination of this Agreement. YKHC shall have the
right to examine and audit Carrier's records and the records of Carrier's
subcontractors upon good faith written or oral request. Carrier shall make the
requested records available to YKHC at Carrier's place of business in Anchorage,
Alaska within ten (10) calendar days from the date of YKHC's request. YKHC shall
be entitled to copy all such records, at YKHC's expense.

13.      CONFIDENTIALITY

         Carrier shall comply with all YKHC written policies and all laws and
regulations governing the maintenance and release of medical records and
confidentiality of patient information, and all standards promulgated by any
relevant accrediting agency. YKHC shall advise Carrier of YKHC's policies and,
to the extent practicable, applicable laws, regulations and accrediting agency
standards. Carrier and YKHC shall endeavor to jointly provide orientation and

AIR AMBULANCE SERVICES AGREEMENT                                    Page 7 of 13

<PAGE>

training to Carrier's employees to guard against violations of patient
confidentiality. Carrier nonetheless bears the ultimate responsibility for
ensuring that Carrier's employees, agents, representatives and subcontractors do
not breach any such patient confidentialities.

         The parties will each treat as proprietary and confidential any
information belonging to the other party disclosed during the term of this
Agreement.

14.      DRUG-FREE WORKPLACE

         Carrier is subject to federal laws and regulations concerning drug-free
work places, drug testing and related requirements. Carrier shall comply with
all applicable federal, state and local laws concerning drug and alcohol use and
distribution and agrees, to the extent not inconsistent with applicable law, to
comply with YKHC's drug free workplace policy.

15.      STAFF CLEANLINESS AND APPEARANCE

         Carrier's staff shall maintain a neat and clean personal appearance
when providing any of the services set forth in this Agreement and/or when
dealing with YKHC's personnel or patients.

16.      INDEPENDENT CONTRACTOR

         Carrier is an independent contractor. Nothing in this Agreement or in
the activities or relationship of the parties is intended to or should be
interpreted or construed to be that of employer/employee, joint venturer,
partner, or agent to, with or of YKHC. Carrier assumes full responsibility for
the actions of its employees, agents and representatives while performing
services pursuant to this Agreement, and Carrier shall be solely responsible for
their supervision, direction, control and payment of salary, wages and benefits.
Carrier shall be solely responsible for obtaining workers' compensation
insurance for its employees and paying all monies and filing all reports and
forms associated with Carrier's employees, services and operations. YKHC assumes
full responsibility for the actions of its employees, agents and representatives
while performing services pursuant to this Agreement, and YKHC shall be solely
responsible for their supervision, direction, control and payment of salary,
wages and benefits. YKHC shall be solely responsible for obtaining workers'

reports and forms associated with YKHC's employees, services and operations.

17.      NON-ASSIGNMENT AND NON-SUBCONTRACTING

         Neither party may assign nor subcontract its performance or obligations
without prior written consent of the other party, and any such consent may be
withheld with or without cause, in the absolute discretion of the party
withholding such consent. Notwithstanding the previous sentence, American Air
Network, Inc. and its principals may desire to form a separate legal entity to

AIR AMBULANCE SERVICES AGREEMENT                                    Page 8 of 13

<PAGE>

assume Carrier's responsibilities under this Agreement, and in that event YKHC
shall not unreasonably withhold consent to the assignment of this Agreement to
that new entity. Regardless of any assignment or subcontracting to another
entity, America Air Network, Inc. shall remain liable to YKHC for any damages,
including but not limited to liquidated damages, and to defend, hold harmless
and indemnify YKHC, all as set forth in this Agreement. The prior sentence
provides no rights or remedies to third parties.

18.      REMEDIES

                  18.1 CARRIER'S DUTY TO NOTIFY YKHC OF ANTICIPATED INABILITY TO
MEET CONTRACT REQUIREMENTS. If Carrier knows or with exercise of reasonable
diligence should know that it cannot meet the 45 minute "wheels up" deadline set
forth in Section 2.2, Carrier shall immediately notify YKHC's Director of Flight
Services or his/her designee. Upon receipt of such notice YKHC shall have the
exclusive right and discretion to select and hire a replacement or substitute
carrier. Carrier shall reimburse YKHC for the amount by which YKHC's cost of
replacement exceeds the amount that YKHC would have paid Carrier in accordance
with EXHIBIT A had Carrier timely flown the flight. In addition, if a
replacement carrier's "wheels up" time exceeds 45 minutes after YKHC's dispatch
to Carrier, then YKHC shall be entitled to damages from Carrier calculated in
accordance with Section 18.3 using the "wheels up" time of the replacement
carrier. The remedies provided in this subparagraph are non-exclusive, and shall
not restrict YKHC's other remedies in the event YKHC is unable to secure a
replacement.

                  18.2 DISCUSSION OF NONCOMPLIANCE. If Carrier at any time (i)
fails to meet the dispatch "wheels up" time required by this Agreement; or (ii)
fails to otherwise be mission ready as required by this Agreement, Carrier shall
candidly present the circumstances surrounding such failure to the Operations
Review Group at its next meeting. The Operations Review Group shall review the
facts and, if the failure was unintentional and not in bad faith, discuss
recommendations for avoiding recurrence. Intentional or bad faith breaches of
the "Mission Readiness" requirement shall constitute a breach and be grounds for
termination.

                  18.3 LIQUIDATED DAMAGES FOR BREACH. In the event of Carrier's
failure to meet the Mission Readiness requirements of this Agreement, and
notwithstanding YKHC's election of any other remedy, YKHC shall be entitled to
receive as liquidated damages Two Thousand Dollars ($2,000.00) per occurrence.
If after 12 hours from the time of the oral or written dispatch from YKHC
Carrier is still unable to provide the aircraft and/or crew to be dispatched, or
an appropriate replacement aircraft and crew, YKHC shall be entitled to receive
as liquidated damages an additional Five Hundred Dollars ($500.00) per hour for
every hour until Carrier has provided an aircraft and crew consistent with the
requirements of this Agreement in mission ready condition, to a maximum of
Twelve Thousand Dollars ($12,000.00) per 24 hour period until a mission ready
aircraft and crew are available for a possible future dispatch or a replacement
aircraft and crew are provided by Carrier. YKHC shall be entitled to deduct all
such liquidated damages from payments otherwise owed to Carrier.

         Carrier acknowledges that the above-stated liquidated damages are a
reasonable estimate of the losses YKHC will incur in the event of Carrier's
failure to meet contract standards of Mission Readiness.

                  18.4 OTHER. The remedies set forth above are non-exclusive,
and YKHC shall be entitled to all other remedies permitted by this Agreement
and/or by law.

         B.       CARRIER

                  18.5 NOTICE OF CLAIM. Carrier shall immediately inform YKHC's
Legal Department, P.O. Box 528, Bethel, Alaska 99559, in writing of any act or
occurrence that may form the basis of a claim by Carrier against YKHC.

                  18.6 CLAIM FOR PAYMENT. If the matter involves a claim for
payment to Carrier and it cannot be resolved within seven (7) calendar days,
Carrier shall thereafter, within the next 14 days, submit a written notice of
the claim. Carrier shall, in presenting this claim, include the facts and
circumstances surrounding the claim, the specific relief requested, all
calculations supporting any requested compensation, and the provisions of this
Agreement under which the claim is made. YKHC shall review the claim and provide
a written decision concerning the claim to Carrier within 14 days of YKHC's
receipt of the written notice of the claim. Accompanying YKHC's written decision
shall be payment by YKHC of all portions of the claim that YKHC does not
dispute. This procedure covers all claims for payment that Carrier may have, and
Carrier must exhaust these remedies before proceeding in any other manner.
Carrier agrees that failure on its part to timely abide by these requirements
shall constitute a waiver of any such claim.

                  18.7 OTHER CLAIMS. If the matter involves a claim other than
for payment to Carrier and it cannot be resolved within 14 calendar days,
Carrier shall thereafter, within the next 28 days, submit a written notice of
the claim. Carrier shall, in presenting this claim, include the facts and
circumstances surrounding the claim, the specific relief requested, all
calculations supporting any requested compensation, and the provisions of this
Agreement under which the claim is made. YKHC shall review the claim and provide
a written decision concerning the claim to Carrier within 28 days of YKHC's
receipt of the written notice of the claim. This procedure covers all claims
other than for payment that Carrier may have, and Carrier must exhaust these
remedies before proceeding in any other manner. Carrier agrees that failure on
its part to timely abide by these requirements shall constitute a waiver of any
such claim.

                  18.8 CARRIER'S OTHER REMEDIES. Following Carrier's notices as
set forth above, the parties shall use reasonable efforts to resolve the claim
or dispute. Carrier shall continue to diligently and fully perform under this
Agreement, regardless of the status or resolution of such claim or dispute. If
Carrier is dissatisfied with YKHC's ultimate decision, Carrier may only then
pursue other remedies that may be allowed by Section 19 of this Agreement or by
law.

19.      TERMINATION

         Except as provided in Section 1 to this Agreement, YKHC or Carrier may
terminate this Agreement only for cause, upon not less than 90 days written
notice to the defaulting party. Cause shall include any material breach of this
Agreement. Where a breach of this Agreement is curable, the defaulting party
shall correct any identified breach or default of this Agreement as soon as
reasonably possible, not to exceed 30 days after notice, or in the case of a
failure to pay Carrier an amount due, 10 days after the second notice Carrier is
required to give pursuant to Section 18.6. Failure to cure within the notice
period allows the termination to become effective.

         Additionally, YKHC may terminate this Agreement and may pursue all
other remedies allowed by law, without waiver of YKHC's right to seek or offset
liquidated damages or waiver of any other remedy, in the event of Carrier's
three (3) non-consecutive failures within any 30 day period to meet the Mission
Readiness requirements of this Agreement. Termination on this basis shall be
effective 60 days after written notice by YKHC. The notice of termination shall
be void and this Agreement reinstated if within those 60 days Carrier has no
further failures to meet Mission Readiness requirements or other breaches, the
intent being that Carrier will essentially be on "probation" during these 60
days.

20.      INDEMNIFICATION

         Carrier shall indemnify, defend and hold harmless YKHC and its
directors, officers, attorneys, employees, agents, successors and assigns
(collectively "YKHC") from and against any and all actions, claims, demands,
liabilities, costs and expenses that may in any manner be imposed on or incurred
by YKHC for loss or damage to property or for injuries to or deaths of persons
arising from or relating to this Agreement or any act, default or omission of
Carrier, its directors, officers, attorneys, employees, agents, subcontractors,
successors and assigns, excepting any such actions, claims, demands,
liabilities, costs or expenses that arise solely from YKHC's negligence,
recklessness or intentional misconduct.

         YKHC shall hold Carrier harmless from and against all third-party
claims, liabilities, losses, costs and damages to the extent such arise out of
medical services furnished by YKHC or any assignee or contractor other than
Carrier.

21.      APPLICABLE LAW, VENUE AND ATTORNEYS' FEES/COSTS

         In the absence of controlling federal law, this Agreement is governed
and will be construed in accordance with the laws of the State of Alaska,
provided, however, that nothing in this Agreement shall or may be construed to

AIR AMBULANCE SERVICES AGREEMENT                                   Page 11 of 13

USC 1680c(d), Public Law 101-512 ' 314, as amended by Public Law 103-138 ' 308,
or by any other law. YKHC similarly reserves to itself any other protections,
including protection from suit based on common law immunities. Venue and all
proceedings relating in any way whatsoever to this Agreement shall be brought in
federal or state court for the State of Alaska located in the Third or Fourth
Judicial District, at Anchorage or Bethel, Alaska. The prevailing party shall be
entitled to recover all actual costs and attorneys' fees incurred.

22.      WAIVER AND SEVERABILITY

         Any waiver by either party of any provision of this Agreement, or a
failure to enforce any breach, shall not be construed to be a waiver of any
other provision of this Agreement or a future waiver, unless that intent is
expressly stated in writing.

         If any section, sentence or clause of this Agreement is judged to be
illegal or unenforceable, such illegality or unenforceability shall not affect
the validity of the remainder of this Agreement.

23.      INTEGRATION

         This Agreement is the entire, integrated contract between the parties,
and supersedes all prior negotiations, representations, understandings or
agreements, whether written or oral, express or implied. This Agreement may be
amended or modified only in a written amendment signed by both parties. The
parties further represent that they have each been represented by counsel of
their choice, and that this Agreement is the product of arm's length
negotiations.

         Notwithstanding the above paragraph and the execution of this
Agreement, this Agreement shall be null and void if Carrier does not provide by
the effective date the following documents: executed Space Use Agreement, FAR
Part 135 certificate, Alaska business license, Articles of Incorporation,
certificate of corporate good standing, corporate resolution, insurance
certificates, and such other documents that may reasonably be required.

                  EXHIBIT A TO AIR AMBULANCE SERVICES AGREEMENT

         American Air Network, Inc. ("Carrier") agrees to base, dedicate and
make available in Anchorage, Alaska the following two (2) aircraft, plus one (1)
backup aircraft, related equipment, flight crews and support services in
Anchorage, Alaska, for the purposes of fulfilling Carrier's duties arising under
the Air Ambulance Services Agreement ("Agreement") with Yukon-Kuskokwim Health
Corporation ("YKHC"). YKHC shall compensate Carrier for said aircraft,
equipment, flight crews and support services only as set forth in this Exhibit
A, and YKHC shall not be responsible for any other costs, expenses, taxes or
charges.

1.       AIRCRAFT DESCRIPTION
         --------------------

         1.1 AIRCRAFT #1: Learjet 35A, having FAA Registration Number N38NW and
Serial Number 156, or FAA Registration Number N298NW and Serial Number 298.

         1.2 AIRCRAFT #2: Citation II, having FAA Registration Number N120JP and
Serial Number 478.

         1.3 AIRCRAFT #3: Backup aircraft similar in capabilities and quality to
Aircraft #1 and/or Aircraft #2.

2.       AIRCRAFT RATES AND PAYMENT
         --------------------------

                  2.1 MONTHLY 200 HOUR ADVANCE PAYMENT. YKHC shall compensate
Carrier at the rate of One Thousand Seven Hundred Dollars and No Cents
($1,700.00) per flight hour per aircraft for the first 200 hours collectively
flown by Carrier's aircraft in any calendar month. Such payment shall be made by
YKHC in advance. Carrier shall provide an invoice for this charge no later than
five (5) days prior to the effective date of this Agreement, and YKHC shall
tender this 200 hour advance payment on or before the effective date. Thereafter
Carrier shall provide an invoice for this 200 hour advance no later than five
(5) business days before the end of each month, and YKHC shall tender this 200
hour advance payment on or before the first day of each month. If during any
given month Carrier accumulates fewer actual flight hours than the 200 hours,
YKHC shall be entitled to deduct from the next month's payments the difference
between the actual flight hours and the prior month's 200 hour advance payment,
the intent being that Carrier is to be paid only for actual flight hours, with
no guaranteed minimum.

                  By no later than the 15th day of each month Carrier shall
submit to YKHC a statement itemizing each flight that comprised the prior
month's 200 hours. This statement shall be in the form of Carrier's other
invoices, and shall specify the departure and landing location for each specific
flight (including any intermediate landing and takeoff locations), and any other
information that YKHC may reasonably request

EXHIBIT A TO AIR AMBULANCE SERVICES AGREEMENT                        Page 1 of 8

<PAGE>

                  2.2 FLIGHT HOURS ABOVE THE 200 HOUR ADVANCE PAYMENT, AND
REIMBURSABLE EXPENSES. After the minimum of 200 hours has been achieved, YKHC
shall compensate Carrier at the rate of One Thousand Five Hundred Dollars and No
Cents ($1,500.00) per flight hour for the Lear 35s, and One Thousand Three
Hundred Fifty Dollars and No Cents ($1,350.00) per flight hour for the Citation
II. On or before the 15th day of each month Carrier shall provide an invoice
itemizing the flight hours for each flight, the departure and landing location
for each specific flight (including any intermediate landing and takeoff
locations), and any other information that YKHC may reasonably request. Carrier
shall also invoice YKHC for any requested reimbursable expenses, pursuant to
Section 3 below. YKHC shall pay all such invoices within 30 days of YKHC's
receipt of the invoice.

                  2.3 DRY RATES. The aircraft rates are "dry" rates, meaning
that YKHC shall be responsible for paying for all fuel used by Carrier's
aircraft (but not oil or other liquids). Carrier shall purchase the fuel and be
reimbursed by YKHC as set forth in Section 3, below.

                  2.4 SUPPLEMENTAL AIRCRAFT. If Carrier provides any
supplemental aircraft beyond those listed in this Exhibit A, such supplemental
aircraft shall be compensated at a flight hour rate to be mutually agreed upon
in writing, and all other provisions of this Exhibit A and the Agreement shall
apply.

3.       REIMBURSABLE EXPENSES
         ---------------------

         YKHC shall reimburse Carrier for all expenses set forth in this Section
3, but only in the actual amount of such expenses, with no markup. Carrier shall
provide YKHC with copies of invoices and receipts evidencing such reimbursable
expenses with Carrier's billing for same.

         A. EXPENSES INCURRED AWAY FROM CARRIER'S HOME BASE. Carrier's home base
is at Ted Stevens Anchorage International Airport. YKHC shall reimburse Carrier
for those expenses stated below incurred by Carrier in performing its duties
under this Agreement which result from operating, maintaining or otherwise
providing aircraft, crew and equipment away from Carrier's home base. Such
reimbursable expenses are limited to:

                  3.1 AIRPORT AND NAVIGATION FEES. Landing, navigation, parking
and overnight fees other than those charged by or at the Anchorage International
Airport. "Navigation" fees, as used herein, shall include only the following:
Use fees and service charges of any nature by a government agency paid by
Carrier relating to Carrier's use of foreign air space, navigation services or
other flight services in performing a mission under this agreement.

<PAGE>

                  3.2 ROOM AND BOARD. Room, board, local transportation and
other costs incurred by flight crew members (but not maintenance or other
personnel) incurred outside of Anchorage, Alaska in performing Carrier's duties
under this Agreement.

                  3.3 VISAS, INTERNATIONAL TRAVEL AUTHORIZATIONS, ETC. Amounts
paid by Carrier for visas, vaccinations or similar expenses relating to
international flights performed at YKHC's written request under this Agreement.
Notwithstanding YKHC's duty to pay for the above charges, Carrier shall be
responsible for procuring all flight plans, visas, landing and over-flight
clearances, authorizations and approvals for international transports.

                  3.4 FUEL. Amounts paid by Carrier for fuel. If YKHC becomes
aware of a fuel supplier at the same airport providing fuel at costs below those
being invoiced by Carrier, YKHC may provide written notice to Carrier of the
lower fuel costs, and the parties shall discuss the feasibility of this
alternative fuel supplier at the Operations Review Group meeting. If the parties
cannot amicably agree on which fuel supplier to use, YKHC may thereafter
reimburse Carrier for only the rate charged by the lower cost fuel supplier.

                  3.5 OTHER. Other expenses incurred by Carrier (other than
those relating to maintenance of aircraft or equipment required to be supplied
by Carrier), which would not have been incurred by Carrier but for Carrier
performing services for YKHC outside of Anchorage, Alaska. YKHC shall only be
required to reimburse Carrier for these other expenses that in the aggregate do
not exceed Five Hundred Dollars and No Cents ($500.00) in any one calendar
month. YKHC may, in its sole discretion, approve or disapprove reimbursement for
costs exceeding this amount.

         B.       EXPENSES INCURRED AT CARRIER'S HOME BASE
                  ----------------------------------------

                  3.6 FUEL. Amounts paid by Carrier for fuel. If YKHC becomes
aware of a fuel supplier at Anchorage International Airport providing fuel at
costs below those being invoiced by Carrier, YKHC may provide written notice to
Carrier of the lower fuel costs, and the parties shall discuss the feasibility
of this alternative fuel supplier at the Operations Review Group meeting. If the
parties cannot amicably agree on which fuel supplier to use, YKHC may thereafter
reimburse Carrier for only the rate charged by the lower cost fuel supplier.

                  3.7 OTHER. Except as otherwise expressly provided in this
Agreement and its Exhibits, YKHC is not required to reimburse Carrier for any
expenses incurred by reason of Carrier's performance of any duties or providing
any property or services for the benefit of YKHC at Anchorage International
Airport or in Anchorage.
