                 b.    The balance of the purchase price as provided in
                 subsection 4(a)(2) above will be evidenced by a Promissory
                 Note from Era to AHI in the amount of $6,971,575 (the "Note")
                 in the form of Attachment J hereto, and secured by the
                 Aircraft under a Security Agreement in the form of Attachment
                 K hereto (the "Security Agreement") until such time as each
                 Aircraft is sold or selected in accordance with this
                 subsection 4(b).  The Note shall bear no interest and shall be
                 payable on or before the first anniversary of the date of
                 Closing.  The parties anticipate that Era will sell all or
                 some of the Aircraft to third parties or select all or some of
                 the Aircraft for Era's own use.

                       1.  Upon sale of each Aircraft to a third party, Era
                       shall pay AHI the Formula Value listed on Attachment B
                       for that Aircraft, and each such payment shall be
                       applied as a credit to the balance owing under the Note.

                       2.  Upon selection by Era of any of the Aircraft for its
                       own use, Era shall pay AHI the Formula Value listed on
                       Attachment B for that Aircraft, and each such payment
                       shall be applied as a credit to the balance owing under
                       the Note.  Era shall make every effort to make any such
                       selections within 60 days of Closing; however, should
                       Era's business circumstances change, Era shall not be
                       precluded from selecting any of the Aircraft for its own
                       use at a later date.

                       3.  Any remaining balance of the Note not sooner paid
                       shall be due and paid in full on or before the first
                       anniversary of the date of Closing.

                 Upon payment for any Aircraft as provided in this subsection
                 4(b), AHI shall immediately release any security interest of
                 AHI in such Aircraft.  Upon final payment of the balance of
                 the Note, AHI shall immediately release any remaining security
                 interests.

                 5.    STATUS OF TITLE.

                 a.    BIJO ASSETS AND REAL PROPERTY LEASEHOLDS.  At Closing,

                 policy shall be issued as of the date of Closing and shall be

                 cured to the satisfaction of Buyer by the mere payment of
                 money shall be satisfied by BIJO out of BIJO's proceeds of
                 sale.  In the event there are title objections which cannot be
                 remedied by the mere payment of money, then Buyer shall have
                 the option to unconditionally revoke this Agreement and
                 receive full reimbursement by Sellers of all of Buyer's out of
                 pocket expenses advanced pursuant to the terms of this

                 for the Aircraft.  The Bills of Sale shall convey marketable
                 title and all of Sellers' right, title and interest in the

                 are currently under contract to third party customers.  Such
                 contracts are described in Attachment F.  To the extent

                 conditions occurring or existing on or before the date of
                 Closing.  Buyer shall pay all costs and penalties arising out
                 of or relating to any remediation or cleanup required as the

                 of any building or asset located upon or erected upon the BIJO
                 leased premises; and Buyer shall give BIJO reasonable notice
                 of any such claims for indemnity and an opportunity to

                 shall indemnify the other party or parties to the extent any
                 such commissions or fees are attributable to the indemnifying

                 Guarantor's or either Seller's articles of incorporation, as
                 amended, or its bylaws, as amended, or its partnership

                 respective assets are bound; or constitute any event which
                 with notice, lapse of time, or both, would result in any such
                 conflict, breach, default or right.

                 e.    Without limiting the foregoing provisions of this
                 Section 14, the execution, delivery and performance of this
                 Agreement and consummation of the transactions contemplated
                 herein, have been duly authorized and approved by the
                 respective boards of directors and partners.

                 f.    All Assets that are real or tangible personal property
                 held by each Seller under leases are held under lease
                 agreements that are valid and binding and in full force and
                 effect.  For each Seller which has a current lease, such

                 has been received by such Seller, and no party thereto is in
                 default or alleged to be in default thereunder.  For each
                 Seller which has such a lease, none of the rights under any
                 such lease will be impaired by the consummation of the
                 transactions contemplated by this Agreement, assuming that the
                 consent and

                 are no claims, actions, suits or proceedings, or governmental
                 or administrative investigations pending or threatened against
                 the respective Seller or any of its Assets.

                 in accordance with their respective terms.  There are no
                 defaults by AHI thereunder and AHI knows of no defaults
                 thereunder by any other party thereto, and no event has
                 occurred that with the lapse of time or action or inaction by
                 any party thereto would result in a violation thereof or a
                 default thereunder.  None of the rights to the AHI Assets or
                 under the Permits or Other Assets will be impaired by the
                 consummation of the transactions contemplated by this
                 Agreement, and all such rights will inure to and be
                 enforceable according to their respective terms by Buyer after
                 the date of Closing without the authorization, consent,
                 approval, permit or license of, or filing with, any other
                 person.  None of the rights to the AHI Assets or under the
                 Permits or Other Assets referenced in this subsection 14(h)
                 have been or are threatened to be revoked, canceled, suspended
                 or modified.

                 have delivered to Buyer complete copies of all Permits,
                 As-Built Drawings and plans and specifications of the
                 improvements to the Real Property, and other documents and
                 records related to the Assets.

                 j.    To the best of Guarantor's, BIJO's and AHI's knowledge:
                 no BIJO Asset is or has been in violation of, or is subject to
                 a remedial or reporting obligation under, any Environmental
                 Laws; there are no underground storage tanks, pits, sumps or
                 impoundments, as defined under any applicable Environmental
                 Laws, on any of the Real Property, except a 300 gallon
                 underground storage tank on Lot 5-B; Sellers have received no
                 notice of any violation or non-compliance with, or remedial
                 obligation under Environmental Laws (except the removal of a
                 gasoline storage tank on Lot 5-B, which was done in the summer
                 of 1992); and there are no outstanding injunctions, decrees,
                 orders, judgments, lawsuits, claims, proceedings or
                 investigations pending or threatened under Environmental Laws
                 relating to the Real Property.  However this section as it
                 relates to BIJO does not put any affirmative duty on BIJO to
                 perform any environmental audit, inspection or make any
                 inquiry other than what is presently known by the partners of
                 BIJO.  BIJO has furnished to Buyer copies of documents it has
                 relating to the environmental conditions on the property, but
                 BIJO disclaims any expertise in such matters, and does not
                 warrant that the





Asset Purchase and Sale Agreement                                  page 11 of 57
   13
                 information contained in such copies of documents is true or
                 accurate.

                 k.    Guarantor and each Seller is not insolvent, nor will
                 such party be rendered insolvent by the transactions
                 contemplated by this Agreement.

                 l.    All taxes on the Assets owned by each Seller which have
                 come due have been paid.

                 m.    The tangible AHI Assets are in good operating condition,
                 order and repair, subject to ordinary wear and tear, and have
                 been maintained in accordance with standard industry practice,
                 and conform in all material respects with all applicable legal
                 requirements.  The Aircraft and Parts are airworthy, except
                 for such Parts as are indicated otherwise by appropriate
                 maintenance or other inventory or work in progress records.
                 The aircraft maintenance records shall be accurate as of
                 closing.

                 n.    To the best of BIJO's knowledge, improvements to the
                 Real Property and fixtures did not violate applicable
                 building, fire or other applicable codes at the time
                 constructed, modified, installed, repaired or reconstructed.
                 However this statement as it relates to BIJO does not put any
                 affirmative duty on BIJO to perform any inspection or make any
                 inquiry other than what is presently and actually known by the
                 partners of BIJO.  BIJO has furnished to Buyer copies of
                 documents it has relating to the construction of the building,
                 but BIJO disclaims any expertise in such matters, and does not
                 warrant that the information contained in such copies of
                 documents is true or accurate.

                 o.    There are no assets of the kinds contemplated to be sold
                 under this Agreement that have not been fully disclosed to
                 Buyer and that are not in fact being sold under this
                 Agreement.

                 p.    BIJO has no employees and no employee pension plans; AHI
                 does not participate in any Multi- employer Pension Plan and
                 is subject to no employee collective bargaining agreement.

                 15.   BUYER'S REPRESENTATIONS AND WARRANTIES.  Buyer 
represents and warrants to Sellers that the following are true and correct on
and as of the date of this Agreement and will be true and correct through the
date of Closing as if made on and as of that date:

                 a.    Buyer is a corporation duly organized, validly existing
                 and in good standing under the laws of the State of Washington
                 and is qualified to transact business and is in good standing
                 in the State of Alaska.  Buyer has the corporate power and
                 authority to own, lease or operate all properties and assets
                 now owned, leased or operated by it and to carry on its
                 business as now conducted.

                 b.    Buyer may execute, deliver and perform this Agreement
                 without the necessity of obtaining any consent, approval,
                 authorization or waiver or giving any notice or otherwise,
                 except for





Asset Purchase and Sale Agreement                                  page 12 of 57
   14
                 the consent and approval of the State of Alaska to the
                 Assignments of Lease Agreement related to the Real Property
                 expressly contemplated by this Agreement.

                 c.    The execution, delivery and performance of this
                 Agreement do not and will not constitute a violation of the
                 articles of incorporation, as amended, or the bylaws, as
                 amended, of Buyer, or constitute a violation or default under
                 any contract to which Buyer is a party.

                 d.    The execution, delivery and performance of this
                 Agreement have been duly authorized by Buyer, and this
                 Agreement constitutes the legal, valid and binding obligation
                 of Buyer.

                 e.    Buyer is not, nor will the execution of this Agreement
                 cause Buyer to become, insolvent.

                 16.   GUARANTOR GUARANTY.  Guarantor unconditionally
guarantees each and every obligation of AHI under this Agreement as set forth
in Attachment M.

                 17.   LAWS OF ALASKA, AMBIGUITIES, GOOD FAITH PERFORMANCE.
Every provision of this Agreement shall be construed and enforced in accordance
with the laws of the State of Alaska.  The canon of contract interpretation
that ambiguities, if any, in a writing be construed against the drafter shall
not apply to this Agreement.  The parties agree to do such things and execute
such further documents and assurances, including without limitation title or
escrow closing instructions, as may be necessary or advisable in order to carry
out the terms and conditions of this Agreement.  Whenever the context so
requires, the singular of Sellers includes the plural and the plural of Sellers
includes the singular.

                 18.   ACTIONS, JURISDICTION AND VENUE.  If any of Guarantor,
AHI, BIJO or Buyer fails or refuses to comply with the conditions agreed to by
it or to perform any of its respective obligations hereunder, any legal action
or other proceeding for the enforcement of this Agreement or because of an
alleged dispute, breach, default or misrepresentation in connection with this
Agreement or the transactions contemplated hereby, shall be maintained in the
appropriate court located in Anchorage, Alaska.  The prevailing party in any
such action or proceeding shall be entitled to recover full reasonable
attorneys fees and costs in addition to any other relief to which it may be
entitled.

                 19.   ASSIGNMENT, MODIFICATION, ENTIRE UNDERSTANDING OF
PARTIES.  The rights or obligations of Guarantor or either Seller hereunder
shall not be assigned without the prior written consent of Buyer.  Any
purported assignment without such prior written consent shall be void.

                       This Agreement may be modified with the mutual consent
of all the parties; provided, however, that no such modification shall be valid
or binding unless such modification is in writing, duly dated and signed by
Guarantor, Sellers and Buyer.  This Agreement, with its Attachments, which are
incorporated by reference as though set forth in full herein, constitutes the
entire agreement between the parties.  No party shall be bound by any other
terms, conditions, statements or representations, oral or written, not herein
contained.





Asset Purchase and Sale Agreement                                  page 13 of 57
   15
Each party hereby acknowledges that in executing this Agreement, it has not
been induced, persuaded or motivated by any promise or representation made by
any other party unless expressly set forth herein.  All previous negotiations,
statements, and prior offers by the parties or their representatives, including
the document signed the 18th day of August 1995 by Era, AHI and BIJO, are
superseded by and merged into this Agreement.

                 20.   WAIVER.  Any waiver of any term or condition of this
Agreement, or any amendment of this Agreement, shall be effective only if in
writing and signed by the waiving party.  A waiver of breach or failure to
enforce any of the terms or conditions of this Agreement shall not in any way
affect, limit or waive a party's rights at any other time to enforce strict
compliance thereafter with every term or condition of this Agreement.

                21.    SURVIVAL.  All warranties, covenants, representations
and obligations contained in this Agreement or in any certificate, assignment,
document or other instrument delivered in connection herewith shall survive the
Closing and will not be affected by any investigation, verification, or
approval by any party or anyone on behalf of any party.

                22.    ACCESS TO RECORDS AND OPERATIONS.  Between the date of
this Agreement and Closing:  (a) Each Seller shall give Buyer, its agents and
representatives, access to its respective Assets and related records and
furnish such information with respect to Sellers and the Assets as Buyer shall
from time to time reasonably request;  (b) AHI and BIJO shall operate only in
the ordinary course of their respective businesses and in compliance with all
applicable laws and regulations;  (c) Sellers shall not enter into any
transaction or contract, or amend or terminate any transaction or contract,
substantially affecting the value of any Asset, normal wear and tear excepted;
(d) Each Seller shall cause the tangible Assets owned by it to be maintained
and repaired in accordance with past practices of Sellers, except that Sellers
shall not contract with any third party or parties for repair or service of any
Assets without Buyer's written consent, which consent shall not be unreasonably
withheld;  (e) Each Seller shall cause its respective Assets to be operated and
maintained so that the representations and warranties of such Seller contained
herein shall continue to be true and correct on and as of the date of Closing;
(f) Each Seller and Buyer shall advise the others promptly in writing of any
condition or circumstance, known to it, occurring from the date of this
Agreement to and including the date of Closing that would cause the respective
representations and warranties of the respective Seller or Buyer contained
herein or contemplated by this Agreement to become untrue in any material
respect.

                23.    CONSENTS.  Sellers and Buyer shall use their respective
best efforts to obtain the consent and approval of the State of Alaska to the
Assignments of Lease Agreement and any other required consents relating to the
transactions contemplated by this Agreement.

                24.    SURRENDER.  Within 30 days after Closing, AHI shall
surrender its Air Carrier Operating Certificate to the Federal Aviation
Administration.

                25.    NOTICE.  Any notice required or contemplated under this
Agreement shall be in writing and shall be delivered personally or by telex,
facsimile, United States mail (postage prepaid), or express courier or delivery

                         ADJUSTMENTS TO PURCHASE PRICE


The Parties have agreed that the Purchase Price was established based upon the
actual inventory of Assets as of August 18, 1995. In the event of loss or
damage to the Assets between August 18, 1995, and the date of closing the
Purchase Price shall be adjusted as follows: 

AIRCRAFT:  In the event of a total loss of an Aircraft, the Purchase Price
shall be reduced by the Insured Value listed on Attachment "B" less 10%.  For
repairable damage to an aircraft the Seller shall repair the aircraft to like
condition on August 18, 1995, within 60 days of closing or, in the event of
major damage (estimated repair costs to exceed one half of the insured Value)
at the Buyers option, Seller shall retain ownership of the aircraft and reduce
the Purchase Price by the Insured Value less 10%.  

SPARE PARTS AND COMPONENTS:  In the event of economically repairable damage to
a Part with a new list price exceeding $1,000.00, the Purchase Price shall be
reduced by the average of the Average Overhaul Cost as estimated in the current
Helicopter Equipment Lists and Prices section of The Official Helicopter Blue
Book.  If the part or component is not listed in the Blue Book, the Purchase
Price shall be reduced by an amount equal to 50% of the manufacturer's new list
price for that component.  

In the event of total destruction or loss of a Part the Purchase Price shall be
reduced by 65% of the New Price listed in the current Helicopter Equipment Lists
and Prices section of The Official Helicopter Blue Book.  If the part or
component is not listed in the Blue Book, the Purchase Price shall be reduced by
amount equal to 65% of the manufacturer's new list price for that component.  

VEHICLES AND ROLLING EQUIPMENT: In the event of economically repairable damage
to a Vehicle, the Purchase Price shall be reduced by the repair cost to a like
condition on August 18, 1995, as estimated by a neutral party acceptable to
both Seller and Buyer.  

In the event of destruction or loss of a Vehicle the Purchase Price shall be
reduced by the amount shown under Estimated Value on Attachment D.  If the
vehicle is not listed therein, the Purchase Price shall be reduced by the
estimated fair market value of that item, assuming serviceable condition, as
determined by a neutral party acceptable to both Seller and Buyer.  

FURNITURE, OFFICE MACHINES AND SHOP EQUIPMENT:  In the event of loss or damage
to the office furniture and machines, shop equipment, avionics test equipment
and miscellaneous items and the like, the Purchase Price shall be reduced by an
amount equal to replacement of the lost or damaged item by a comparable piece
of used equipment.  This value shall be determined by mutual agreement between

that AHI, as one of the Sellers named in the Agreement, will faithfully perform
and fulfill every obligation arising out of or pursuant to the Agreement on
AHI's part to be performed or fulfilled, absolute or contingent, secured or
unsecured, direct or indirect, including without limitation all payment
obligations (individually and collectively, the "Obligations").  If AHI fails
to perform the Obligations, then Guarantor shall perform or cause to be
performed all of the Obligations as if they were Guarantor's own obligation by
performing  such Obligations directly or by investing with AHI the necessary
resources to fulfill such Obligations or to have AHI make such other
arrangements as may be necessary for fulfillment by others (which may include
Guarantor), or all of the foregoing, subject to Buyer's consent, which consent
shall not be unreasonably withheld.

        Section 2.2          NATURE OF GUARANTY.  This Guaranty Agreement is an
absolute, irrevocable and continuing guarantee of performance and payment, is
not a guarantee of collection and shall not be diminished or otherwise affected

amendments or extensions made or granted by mutual consent of the parties to
the Agreement shall be conclusively deemed to be consented to by Guarantor. 
Guarantor specifically consents to the jurisdiction of the courts and the law
specified in the Agreement.

        Section 2.3          GUARANTOR'S WAIVERS.  Guarantor hereby expressly
waives presentment for payment, protest, notice of protest, notice of dishonor,
any demand by Buyer and any notice of nonperformance or nonpayment by AHI of

against AHI or any other person liable for the Obligations, (b) enforce its
rights against any other guarantor, (c) proceed or enforce its rights against
or exhaust any security given to secure any portion of the Obligations, (d)
have AHI joined with Guarantor in any suit arising out of this Guaranty
Agreement and/or the Obligations, or (e) pursue any other remedy in Buyer's
power whatsoever.  Buyer shall not be required to mitigate damages or take any
action to reduce, collect or enforce the Obligations.  Guarantor waives any
defense arising by reason of any disability, lack of corporate authority or
power, or similar defense (excepting any defenses provided for in the
Agreement) of AHI or any other guarantor of any portion of the Obligations, and
shall remain liable hereon regardless of whether AHI or any other guarantor be
found not liable thereon for any such reason.  Until the Obligations shall have
been performed or paid in full, Guarantor shall have no right of subrogation. 
Until the Obligations have been performed or paid in full, Guarantor waives any
right to enforce any remedy which Buyer now has or may hereafter have against
AHI, and waives any benefit of any right to participate in any security now or
hereafter held by Buyer. Guarantor shall not raise, and hereby specifically
waives, any defense in any action or proceeding by Buyer seeking performance of
this Guaranty Agreement, or damages for its nonperformance, excepting those
defenses which AHI would be able to raise were such action or proceeding
instituted against AHI based on the Agreement and its performance or
nonperformance of the Obligations.

        Section 2.4          LIABILITY.  It is expressly agreed that the
liability of Guarantor for the payment and performance of the Obligations shall
be as if primary and not secondary.
