                    (B)  in the case of other Taxes, as
determined from the books and records of the DynAir Companies
during the portion of such period ending on the Closing Date and

Closing Date consistent with the past practices of DynCorp and
the DynAir Companies.

               (ii)  Buyer shall cause the DynAir Companies to
file any Returns for any Overlap Period, and Buyer shall pay, or
cause to be paid, all state, local or foreign Taxes shown as due
on any such Returns.

               (iii)  DynCorp shall pay Buyer its share of any
such Taxes (to the extent DynCorp is liable therefor in

paid by DynCorp the DynAir Companies or accrued or otherwise
reflected as a liability on the Final Calculation of Base
Purchase Price due pursuant to the filing of any such Returns
under the provisions of this Section 5.1(b) within five (5)
business days of receipt of notice of such filing by Buyer, which
notice shall set forth in reasonable detail the calculations
regarding DynCorp's share of such Taxes.

               (iv)  Buyer shall pay to DynCorp its share of any
refunds from prior payments of any such taxes within five

administrative or court proceeding relating to Returns described
in Section 5.1(a) with respect to which DynCorp may be liable for
Taxes pursuant to this Agreement (including any such proceedings
relating to the income, properties or operations of the DynAir
Companies); provided, however, that Buyer shall have the right to
participate in any such audit or proceeding to the extent that
any such audit or proceeding may affect the Tax liability of
Buyer, any of its affiliates or the DynAir Companies for any
period ending after the Closing Date and to employ counsel of its
choice at its own expense for purposes of such participation.

               (ii)  Notwithstanding anything to the contrary
contained or implied in this Agreement, without the prior written
approval of Buyer, neither DynCorp nor any affiliate of DynCorp
shall agree or consent to compromise or settle, either
administratively or after the commencement of litigation, any
issue or claim arising in any such audit or proceeding, or
otherwise agree or consent to any Tax liability, to the extent
that any such compromise, settlement, consent or agreement may
affect the Tax liability of Buyer, any of its affiliates or the
DynAir Companies for any period ending after the Closing Date
(including, but not limited to, the imposition of Tax
deficiencies, the reduction of asset basis or cost adjustments,
the lengthening of any amortization or depreciation periods, the

Companies of notice of any pending or threatened Tax audits or
assessments relating to the income, properties or operations of
the DynAir Companies, in each case for Pre-Closing Periods only,
so long as Pre-Closing Periods remain open; provided that failure
by Buyer to comply with this Section 5.1(d)(i) shall not affect
Buyer's right to indemnification relating to Taxes if such
failure does not prejudice the rights of DynCorp,

               (ii)  DynCorp shall promptly notify Buyer in
writing upon receipt by DynCorp or any affiliate of DynCorp of

that failure by DynCorp to comply with this Section 5.1(d)(ii)
shall not affect DynCorp's right to indemnification relating to
Taxes if such failure does not prejudice the rights of Buyer.

          (e)  If the DynAir Companies or any consolidated,
affiliated, combined, unitary or other similar Tax group of which
any of the DynAir Companies is now or was formerly a member has
any reduction in Tax liability by reason of an adjustment with
respect to a Pre-Closing Period and such adjustment has the
effect of decreasing deductions or credits, or increasing income,
for any taxable year or tax period (including an Overlap Period)
ending after the Closing Date, then DynCorp shall pay to Buyer an
amount equal to the Tax detriment attributable to such decreased
deductions or credits, or increased income, as and when the
DynAir Companies or any consolidated, affiliated, combined,
unitary or other similar Tax group of which any of the DynAir
Companies may be a member actually suffers such detriment and is
required to make a payment on account thereof.

          (f)  Neither DynCorp nor any affiliate of DynCorp
shall, without the prior written consent of Buyer, file, or cause

Buyer, any of its affiliates or the DynAir Companies for any
period ending after the Closing Date (including, but not limited
to, the imposition of Tax deficiencies, the reduction of asset
basis or cost adjustments, the lengthening of any amortization or
depreciation periods, the denial of amortization or depreciation
deductions, or the reduction of loss or credit carryforwards).

          (g) (i)  Any and all existing Tax sharing, allocation,
compensation or like agreements or arrangements, whether or not

limitation, any arrangement by which any of the DynAir Companies
makes compensating payments to each other or any other member of
any affiliated, consolidated, combined, unitary or other similar
Tax group for the use of certain tax attributes, shall be
terminated as of the day before the Closing Date (pursuant to a
writing executed on or before the Closing Date by all parties
concerned) and shall have no further force or effect.

               (ii)  All liabilities of the DynAir Companies to
DynCorp or any affiliate of DynCorp (for Taxes or otherwise
pursuant to such agreements or arrangements) shall be canceled on
or prior to the Closing Date.

          (h) (i)  After the Closing Date, Buyer and DynCorp
shall provide each other, and Buyer shall cause the DynAir
Companies to provide DynCorp, with such cooperation and
information relating to the DynAir Companies as either party
reasonably may request in

                    (A) filing any Tax return, amended return or
claim for refund,

                    (B) determining any Tax liability or a right

limitation (and, to the extent notified by any party, any
extensions thereof) of the taxable years to which such returns
and other documents relate and, unless such returns and other
documents are offered and delivered to Buyer or DynCorp, as
applicable, until the final determination of any Tax in respect
of such years.

or other proceeding in respect of Taxes.

               (iv)  Notwithstanding the foregoing, neither Buyer

obligations to indemnify Buyer or the DynAir Companies hereunder:

          (a)  With the exception of tax liabilities which shall
be subject to the limitations set forth in 8.2(b) below, DynCorp
and Seller shall only be liable to indemnify Buyer for breaches
of representations and warranties hereunder that are asserted
against DynCorp in writing prior to December 31, 1996 or, in the
case of representations and warranties pursuant to Sections
3.14(h), 3.20(e)-(m) and 3.22, prior to December 31, 1997.
Thereafter, neither DynCorp nor the Seller shall have any
obligation hereunder to indemnify Buyer for claims asserted after
such date, except to the extent permitted under 8.2(b) below.

          (b)  DynCorp shall be obligated to indemnify Buyer for
tax liabilities arising out of a breach of the covenants
contained in Section 5.1 concerning taxes and taxation, so long
as such claims for indemnification are asserted against DynCorp
in writing on or before the date for the running of the statute
of limitations applicable to such taxes.

          (c)  Neither DynCorp nor Seller shall have any
liability for breaches of representations and warranties under
this Article 8 or any other provision contained in this Agreement
unless and until such liabilities in the aggregate exceed the
amount of $125,000, but in the event such threshold of liability
is reached, then DynCorp and/or Seller shall be liable for the
full amount of such liabilities, provided that in no event shall
DynCorp and Seller have liability to Buyer or the DynAir
Companies for any amount exceeding $2,500,000 in the aggregate
for all claims arising under or in connection with this
Agreement.

     8.3  Indemnification by Buyer. Buyer hereby agrees to
defend, indemnify and hold harmless Seller and DynCorp, their
respective directors, officers and employees and their respective
successors, assigns and affiliates (collectively, "Seller
Indemnities") from and against any and all losses, deficiencies,
liabilities, damages, assessments, judgments, costs and expenses,
including attorneys' fees (both those incurred in connection with
the defense or prosecution of the indemnifiable claim and those
incurred in connection with the enforcement of this provision)
(collectively, "Seller Losses"), resulting from or arising out
of:

          (a) (i)  breaches of representation and warranty
hereunder on the part of Buyer; and

               (ii) failures by Buyer to perform or otherwise
fulfill any undertaking or agreement or obligation hereunder;

          (b)  any and all actions, suits, proceedings, claims
and demands incident to any of the foregoing or such
indemnification; provided, however, that if any claim, liability,
demand, assessment, action, suit or proceeding shall be asserted
in respect of which a Seller Indemnity proposes to demand
indemnification ("Seller Indemnified Claims"), Seller, DynCorp or
such other Seller Indemnity shall notify Buyer thereof, provided
further, however, that the failure to so notify Buyer shall not
reduce or affect Buyer's obligations with respect thereto except
to the extent that Buyer is materially prejudiced thereby; and

          (c)  all liabilities and obligations of the DynAir
Companies arising out of the operations of the DynAir Companies
following the Closing, including, without limitation, liabilities
and obligations subject to the guaranties of DynCorp and its
affiliates that are not released.

Subject to rights of or duties to any insurer or other third
Person having liability therefor, Buyer shall have the right
promptly upon receipt of such notice to assume the control of the
defense, compromise or settlement of any such Seller Indemnified
Claims (provided that any compromise or settlement must be
reasonably approved by DynCorp) including, at its own expense,
employment of counsel reasonably satisfactory to DynCorp;
provided, however, that if Buyer shall have exercised its right
to assume such control, DynCorp may, in its sole discretion and
at its expense, employ counsel to represent it (in addition to
counsel employed by Buyer) in any such matter, and in such event
counsel selected by Buyer shall be required to cooperate with
such counsel of DynCorp in such defense, compromise or
settlement.

                               EXHIBIT A

                    DETERMINATION OF PURCHASE PRICE

(A)  The Purchase Price shall be equal to $7,532,312;

     (1)  Plus the sum of the following

          (i)  Billed Accounts Receivable. The sum of all issued
and outstanding invoices as of the Closing less any subsequent
cash receipts received by the Seller or DynCorp and not remitted
to the Companies and less a reserve for uncollectible accounts.
Included in this category are the billed accounts receivable of
DynAir Parts which have previously been classified as Other
Accounts Receivable.

          (ii)  Unbilled Accounts Receivable and Work In Process.
The sum of all billable but unbilled accounts receivable and work
in process as of the Closing determined, with hindsight, as
follows:

               (a)  For fixed price contracts or tasks within a
contract:  The product obtained by multiplying the fixed price
amount times the percentage obtained by dividing the total direct
costs incurred as of the Closing by the total direct costs
incurred on the task or contract as of the date the task is
completed. In the event that the task or contract is not complete
within 60 days after the Closing, an estimate to complete the
task shall be prepared and the estimated cost shall be added to
the total direct cost.

               (b)  For tasks or contracts that are not fixed price:

                    (1)  The product obtained by multiplying the
contractual labor rate times the hours incurred prior to the
Closing; plus

                    (2)  The billing amount for direct materials
charged to the task or contract including the contractual
material mark ups, handling fees, or other additional charges
pursuant to the contract; plus

                    (3)  The contractual billing amount for other
charges incurred prior to the Closing; plus

                    (4)  The contractual billing amount for
rotables removed prior to the Closing less the estimated costs of
repair; plus

                    (5)  Other billable amounts in accordance
with the applicable contracts.

               (c)  Less any progress billings against the
contract not included in Customer Deposits

          (iii)  Other Accounts Receivable. The sum of all other
accounts billed or billable or otherwise due from third parties
or employees as of the Closing which are not included in items
(i) or (ii) above, calculated at the estimated recoverable
amounts.

     (2)  Less the sum of the following:

          (i)  Accounts Payable. Accounts payable for services
rendered or products received subsequent to the Closing (less
returns subsequent to the Closing) at the amount subsequently
paid or estimated to be paid, including bank overdrafts. Cash
discounts taken subsequent to the Closing shall be deducted from
the otherwise payable amount for purposes of this calculation.

          (ii)  Accrued Salaries and Related Employer and
Withheld Taxes and Fringe Benefits (Accrued Salaries). Accrued
salaries, incentives and bonuses and related employer and
withheld taxes and fringe benefits due to be paid to third
parties for services rendered prior to the Closing. Accrued
salaries for non-hourly employees shall be determined by
pro-rating the subsequent payroll based on the number of calendar
days prior to the Closing and the number of calendar days
subsequent to the Closing. Accrued salaries for hourly employees
shall be determined by calculating the actual wages earned prior
to the Closing.  Amounts payable to the Seller, DynCorp or
parties related to DynCorp shall not be included in the
calculation of Accrued Salaries.

          (iii)  Accrued Vacation Liability. Accrued Vacation
Liability shall be determined by calculating the amounts due to
employees using the same methodology used in the unaudited
combining balance sheets as of March 30, 1995.

          (vi)  Other Accrued Liabilities. Other Accrued
Liabilities shall be determined by calculating the amounts not
other wise covered by this Exhibit due to be paid to third
parties in cash subsequent to the Closing but within one calendar
year thereafter for services rendered or obligations incurred
prior to the Closing.  Amounts payable to the Seller, DynCorp or
parties related to DynCorp shall not be included in the
calculation of Other Accrued Liabilities. Excluded from this
calculation are any Capitalized Lease or Debt obligations
(including the current portion thereof) or any other Long Term
Liabilities. Also excluded from this calculation are accrued or
deferred state or Federal income tax amounts.

          (v)  Sales and Property Taxes. Sales and Property Taxes
shall be equal to the amount of unremitted sales taxes collected
from or billed to customers prior to the Closing and personal
property taxes calculated on a pro-rata basis as of the Closing,
based on the most recently received or paid personal property tax
bills, less disputed amounts. Personal property taxes paid in
advance shall likewise be pro-rated through the Closing and
deducted from Sales and Property Taxes.

          (vi)  Customer Deposits. Customer Deposits and Advances
shall be equal to amounts collected from customers prior to the
Closing and not yet applied against Billed or Unbilled Accounts
for services performed.

(B)  Items which will not be a part of the calculation of the
Purchase Price:  Notwithstanding the above, the calculation of
the Purchase Price shall not include an addition or subtraction
for amounts due to or from DynCorp or any of its subsidiaries or
affiliates.


                            EXHIBIT B

                            REVENUES

GAAP and by the following:

(1)  All amounts billed or billable to customers (a) for services
performed by or under the direction of the DynAir Companies,
including subcontract revenues and/or other billable costs, and
(b) for parts and other products sold.

(2)  Facility sublease revenues and revenues from the DynCorp
Aerospace Technology C-141 drop-in contract, if awarded, shall
not be included in the determination of revenues.

(3)  In the event that the DynAir Companies perform work as a
subcontractor to or joint venturer in other companies owned at
least 30% directly or indirectly by Sabreliner Corporation,
revenues shall be determined based on Time and Materials incurred
with hourly labor charges and material mark-ups being no less
than those in effect between the Companies and McDonnell Douglas
Corporation.

(4)  Revenues on work in process contracts at June 30, 1996 and
1997 shall be determined in accordance with the procedures used
to determine Unbilled Accounts Receivable and Work in Process on
Exhibit A.

          THIS ESCROW AGREEMENT, executed as of            ,
1995, by and among DynCorp Aviation Services, Inc. (the
"Seller"), Sabreliner Corporation (the "Buyer"), and Crestar Bank
(the "Agent),

          WITNESSETH THAT,

          WHEREAS, the Seller and the Buyer have entered into a
Stock Purchase Agreement (the "Agreement"), whereby the Buyer
will purchase certain securities from the Seller;

          WHEREAS, the Agreement provides that certain monies
shall be placed in escrow upon the occurrence of certain events
described more particularly herein; and

          WHEREAS, the Seller and the Buyer have agreed to engage
the agent to hold such monies in escrow and to act in accordance
with the written instructions contained herein in the handling
and delivery of such monies deposited with the Agent pursuant
hereto,

          NOW, THEREFORE, in consideration of the foregoing, of
the mutual promises hereinafter set forth, and of other good and
valuable consideration, the receipt of which is hereby
acknowledged, the parties hereby agree as follows:

ESCROW PROVISIONS

     1.1  Appointment of the Agent.  The Seller and the Buyer
hereby appoint the Agent to serve as escrow agent in connection
with the deposit of funds in connection with disputes relating to
the purchase by the Buyer of certain securities from the Seller,
and the Agent hereby accepts such appointment.

     1.2  Meaning of Terms.  All capitalized terms used herein,
unless otherwise defined herein, shall have the meanings set
forth in the Agreement.

     1.3  Deposit of Funds.  [The Buyer][The Seller] shall
deposit with the Agent, in immediately available funds, $       ,
which is an amount determined by the Seller and the Buyer in
accordance with Section 1.4(c) of the Agreement (the "Disputed
Amount").

     1.4  Receipt Acknowledged; Instructions.  The Agent hereby
acknowledges receipt of the Disputed Amount and agrees to hold
the Disputed Amount and to deliver the Disputed Amount to the
Seller and/or the Buyer upon receipt of, and in accordance with,

     1.5  The Agent's Investment of the Escrow.  The Agent shall
invest the Disputed Amount in short-term securities issued or
guaranteed by the United States Government or money market or
other funds which invest exclusively in short-term securities
issued or guaranteed by the United States Government, including
funds managed by the Agent or a subsidiary thereof.  Upon
distribution, earnings shall be distributed to the Seller and/or
the Buyer, as applicable, in the same ratios as the Disputed
Amount is distributed.

     1.6  Absence of Instructions.  In the absence of
instructions jointly executed by the Seller and Buyer, the Agent
is authorized to deliver the Disputed Amount to the Seller and/or
Buyer in full or partial satisfaction of any final judgment of a
court of competent jurisdiction in favor of such party.  A final
judgment shall be a judgment as to which the period of time for
appealing such judgment has expired without an appeal having been
timely made, or, if an appeal is timely made, as to which such
appeal has been disposed of and there is no recourse to further
appeals.

     1.7  Termination of Agreement.  Following final distribution
of the Disputed Amount and all portions thereof, the Agent shall
close out the escrow and make a final accounting to the other
parties to this Escrow Agreement in accordance with Section 3.1.

AGENT'S LIABILITY

shall not be bound by any agreement or contract other than this
Escrow Agreement.

     2.2  The Agent's Liability.  The Agent acts hereunder as a
depository only and shall have no liability hereunder for the
performance by it in good faith of the acts to be performed
hereunder, except for its own willful misconduct or negligence.
The Agent is not responsible or liable in any manner for the
sufficiency, correctness, genuineness, or validity of any of the
documents deposited with it, and undertakes no responsibility or
liability for the form of execution of such documents or the
identity, authority, title, or rights of any persons deposition
or executing any of the documents.  The Agent shall be authorized
to act on any document believed to be genuine and to be signed by
the proper party or parties and will incur no liability in so
acting.  In the event of any disagreement or the presentation of
the adverse claims or demands in connection with or for any item
affected hereby, the Agent shall, at its option, be entitled to
refuse to comply with any such claims or demands during the
continuance of such disagreement and may refrain from delivering
any item affected hereby, and in so doing the Agent shall not
become liable to the parties, or to any other person, due to its
failure to comply with any such adverse claim or demand.  The
Agent shall be entitled to continue, without liability, to
refrain and refuse to act until all of the rights of the adverse
claimants have been fully resolved among themselves or finally
adjudicated by a court having jurisdiction over the parties and
the items affected hereby.  In the alternative, the Agent may
deposit the items in dispute with the registry of the court
having jurisdiction over the dispute.  The Agent shall be held
harmless and indemnified by the parties hereto in connection with
any claims against it in connection with its acting as the Agent.

     2.3  The Agent's Compensation.  The Agent shall receive as
compensation for services rendered hereunder an initial fee of
$1,000 for the first 90 days of service hereunder, and a monthly
fee of $200 hereafter until the Disputed Amount is finally
disposed of.  The Agent shall be reimbursed for any reasonable
expenses and the actual cost of legal services should the Agent
deem it necessary to retain and attorney.  Compensation or
reimbursement for fees for the periods shall be borne 50% by the
Buyer and 50% by the Seller.  Upon the closing of the escrow in
