The  Information in this  prospectus is not complete and may be changed.  We may
not  sell  these   securities  until  the   post-effective   amendment  to  this
registration  statement  filed with the  Securities  and Exchange  commission is
effective.  This prospectus is not an offer to sell these securities,  and it is

PROSPECTUS

                       [GRAPHIC OMITTED][GRAPHIC OMITTED]

                    11,969,313 Shares of DynCorp Common Stock

                           (Par Value $0.10 per Share)

     DynCorp  originally  offered  11,969,313  shares of common stock, par value
$0.10 per share,  in 1996.  This  prospectus has been revised to present current
information.  Some of those shares have already been sold on our internal  stock
market or distributed  through our benefit plans described below, and 10,486,245
shares remain in this offering.

                        The DynCorp Internal Stock Market

     These  shares may be  offered  and sold on our  internal  stock  market,  a
limited  securities  trading market established by DynCorp to provide employees,
benefit plans, and other  stockholders the opportunity to buy and sell shares of
common stock on selected  days each year at a price  determined  by our Board of
Directors. All offers and sales on the internal stock market by stockholders may
be attributed to DynCorp under the federal  securities laws. We may also sell or
buy shares of common stock on the internal stock market for our own account, but
we will do so only to address  imbalances  between the number of shares  offered
for sale and bid for purchase by stockholders on any particular  trade date. The
internal stock market is managed by our  subsidiary,  DynEx,  Inc. The purchases
and  sales of  shares on the  internal  stock  market  are  carried  out by Buck
Investment Services,  Inc., a registered  broker-dealer,  upon instructions from
the respective buyers and sellers. See "Market Information -- The Internal Stock
Market."

                                     Summary


     There is no present public market for our common stock,  although one could
be  established  in the future.  So, we  established an internal stock market in
1996,  to provide  liquidity  for current  stockholders,  as well as a means for
current employees to acquire common stock through our various benefit plans.

     If the internal  stock market does not give a stockholder a ready means for
selling  shares,  and the  stockholder  cannot find another buyer for his or her
shares of common stock, the  stockholder's  investment could remain illiquid for
an indefinite period.

     All of the  shares of  common  stock  offered  by this  prospectus  will be
subject  to  certain   internal  market  and  by-law   restrictions,   including
restrictions on their  transferability.  Shares  purchased on the internal stock
market  will be subject to  contractual  transfer  restrictions  having the same
effect as those contained in the by-laws.

     The purchase price of the common stock offered by this prospectus is called
the formula  price.  The formula  price will be determined by a formula based on
our  financial  performance.  The formula  price of one share of common stock is
expressed as an equation:

           formula price  =  [(CF x 7)MF + NOA - IBD]
                              ---------------------
                                      ESO

     In this  formula,  "CF" means  operating  cash flow,  which is our earnings
before  interest,  taxes,  depreciation,  and  amortization  for the four fiscal
quarters  preceding the date of a price  valuation.  "MF" means a market factor,
which is a numerical factor that reflects existing  securities market conditions
relevant to the  valuation of the common  stock.  "NOA" means our  non-operating
assets at disposition  value, net of disposition  costs.  "IBD" means the sum of
interest-bearing  debt adjusted to market and other outstanding  securities that
would be satisfied or repaid in a  liquidation  before our common  stock.  "ESO"
means the number of shares of stock outstanding at the date on which a valuation
is made, assuming exercise of all outstanding  options.  See "Market Information
- -- Determination of Purchase Price."

     Our Board of  Directors  reviews the formula  price,  including  the market
factor,  on a quarterly  basis,  in preparation  for internal stock market trade
dates.  The  market  factor  is  reviewed  by the Board in  conjunction  with an
appraisal  that is prepared by an  independent  appraisal firm for the committee
administering our Employee Stock Ownership Plan. Our Board of Directors believes
that the valuation process results in a stock price that reasonably reflects the
value of DynCorp on a per-share basis.

                                  Risk Factors

- --------------------------------------------------------------------------------
         Prior to purchasing  the common stock offered by this  prospectus,  you
         should  carefully  consider  all of the  information  contained  in and
         incorporated  by reference to this  prospectus,  and in particular  you
         should carefully consider the following factors.

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


Substantial Leverage and Ability to Service and Refinance Debt

     Our operations and  acquisitions  are financed  largely through debt rather
than the sale of stock.  Our  indebtedness was $343.2 million as of December 30,
1999, net of discount of $6.5 million,  not including issued but undrawn letters
of credit  of $7.4  million  and  excluding  unused  commitments  available  for
borrowing of $75.6 million. Our stockholders' equity was $16.0 million. Earnings
for the years ended December 31, 1995 were  insufficient  to cover fixed charges
by approximately $4.5 million. For the years ended December 30,1999 and December
31, 1998, 1997, and 1996,  earnings were greater than fixed charges by ratios of
1.5 : 1.0,  2.1 : 1.0, 1.5 : 1.0,  and 2.0 : 1.0,  respectively.  Subject to the
restrictions  in our  existing  financing  agreements,  we may incur  additional
indebtedness  from time to time to finance  acquisitions,  working  capital,  or
capital expenditures and for other purposes.

     The level of our indebtedness could have important consequences, including:

     o   a substantial portion of our cash flow from operations must be
         dedicated to pay interest and repay debt and will not be available for
         other purposes;

     o   our  ability  to obtain  additional  debt  financing  in the future for
         working capital, capital expenditures,  or acquisitions may be limited,
         and, if additional borrowings can be made, they may not be on favorable
         terms; and

     o   our level of indebtedness could limit our flexibility in reacting to
         changes in the industry and economic conditions generally.

     Our  ability to satisfy  our debt  obligations  will depend upon our future
operating performance,  which will be affected by prevailing economic conditions
and  financial,  business,  and  other  factors,  many of which are  beyond  our
control.  If we are unable to  service  our  indebtedness,  we will be forced to
adopt an  alternative  strategy  that may  include  actions  such as reducing or
delaying  capital  expenditures,  selling assets,  restructuring  or refinancing
indebtedness,  or seeking  additional equity capital.  There can be no assurance
that any of these strategies could be effected on satisfactory terms, if at all.
If we are unable to repay our debt as it becomes  due,  the  stockholders  could
lose some or all of their investment.

Restrictions Imposed by Terms of Our Indebtedness

     The  terms of our  agreements  with  banks  and  trustees  relating  to our
indebtedness restrict our ability to incur additional indebtedness, incur liens,
pay dividends or make other restricted payments,  sell certain assets, and enter
into certain kinds of transactions with affiliates, and they impose restrictions
on the ability of  subsidiaries  to pay  dividends or make  payments to DynCorp.
These  agreements also restrict our ability to merge or consolidate with another
company or to sell, assign, transfer, lease, convey, or otherwise dispose of all
or substantially all of our assets.

     In addition, the agreements relating to our various financing arrangements,
which are our senior  subordinated  notes and our revolving credit and term loan
facility,  contain  other  restrictive  covenants.  A  breach  of any  of  these
covenants  could  result  in  a  default  under  those  arrangements.  Upon  the
occurrence  of an event of  default,  the  lenders  could  elect to declare  all
amounts outstanding,  together with accrued interest,  to be immediately due and
payable.  If we were unable to repay those  amounts,  the lenders  could proceed
against the collateral granted to them to secure that indebtedness.

     This aggregate  indebtedness is currently  secured by substantially  all of
the  assets of DynCorp  and its  subsidiaries.  If the  lenders  accelerate  the
payment of such indebtedness, there can be no assurance that our assets would be
sufficient to repay our indebtedness in full.

     Unless we maintain certain  financial  ratios, as defined in the indentures
relating to our senior subordinated notes, after giving effect to newly incurred
indebtedness,  we could not make certain types of additional investments outside
the  ordinary  course of business or incur  additional  indebtedness  beyond the
amounts  available  under  our  revolving  credit  and term  loan  facility.  In
addition,  our revolving  credit and term loan  facility has absolute  limits on
additional  amounts of  indebtedness  we may incur.  As a result,  the amount of
indebtedness  that DynCorp  could incur beyond the amounts  available  under our
revolving credit facility is severely limited.

Dependence on U.S. Government Contracts

     We derived 93% of our revenues for the year ended December 30, 1999, 95% of
our revenues for the year ended  December 31, 1998,  and 97% of our revenues for
the year ended December 31, 1997, from contracts and subcontracts  with the U.S.
Government.  Contracts  with agencies of the  Department of Defense  represented
40%,  40%,  and 45% of our  revenues  for the years ended  December 30, 1999 and
December  31,  1998 and 1997,  respectively.  Continuation  and  renewal  of our
existing  government  contracts and the  acquisition  of  additional  government
contracts is contingent upon the  availability  of adequate  funding for various
U.S.  Government  agencies,  among other  things.  A  significant  decline in or
reapportioning  of U.S.  military  expenditures  could reduce the operations and
maintenance  portion of the defense budget;  that could have a serious effect on
our revenues  and  earnings.  The loss or  significant  curtailment  of material
government contracts would also have a serious effect on our future revenues and
earnings.

Possible Termination of Government Contracts

     Typically,  a government  contract has an initial term of one year combined
with two to four one-year renewal periods,  exercisable at the discretion of the
Government.  The  Government  is not obligated to exercise its option to renew a
contract.  At the time of completion of a government  contract,  the contract is
"recompeted" against all eligible third-party providers.

     Contracts between DynCorp and the U.S. Government or the Government's prime
contractors also contain standard  provisions for termination at the convenience
of the  Government  or such prime  contractors.  There can be no assurance  that
terminations  will not occur, and such  terminations  could adversely affect our
business.

No Assurance of Revenues under Indefinite Delivery, Indefinite Quantity
Contracts

     Many  government   contracts,   particularly  those  involving  information
technology, are indefinite delivery,  indefinite quantity ("IDIQ") contracts. An
agency may award an IDIQ contract to one or more contractors, but the award does
not represent any firm orders for services.  Instead the  contractor(s) may then
identify  specific  projects  and propose to perform the service for a potential
customer covered by the IDIQ contract, and the customer may or may not decide to
order the  services.  Thus,  having  such a contract  does not  assure  that any
revenues will be generated.

Risks Associated with Costs of Performance

     Our  government  contract  services  are  provided  through  three types of
contracts: fixed-price,  time-and-materials,  and cost-reimbursement.  We assume
financial  risk  on  fixed-price  contracts  and  time-and-materials  contracts,
because we assume  the risk of  performing  those  contracts  at the  stipulated
prices or negotiated  hourly rates.  If we do not accurately  estimate  ultimate
costs and control costs during  performance  of the work, we could lose money or
have smaller profits. With cost-reimbursement contracts, so long as actual costs
incurred are within the contract  ceiling and  allowable  under the terms of the
contract,  we are  entitled  to  reimbursement  of the costs  plus a  stipulated
profit.

     From time to time costs which we believe to be payable under  contracts are
questioned by the  Government  and audited.  We cannot  determine the outcome of
ongoing audit findings at this time.

     Government  contract  payments  received  by us for  allowable  direct  and
indirect costs are subject to adjustment after audit by government  auditors and
repayment to the Government,  if the payments exceed  allowable costs as defined
in such  government  contracts.  Audits  have  been  completed  on our  incurred
contract costs through 1996,  except for two  contracts,  and are continuing for
subsequent  periods.  We have included an allowance for possible excess billings
and contract  losses in our financial  statements  which we believe is adequate,
based on our  interpretation  of contracting  regulations  and past  experience.
There can be no assurance, however, that this allowance will be adequate.

Governmental Investigations

     We are  occasionally  the subject of  investigations  by the  Department of
Justice and other investigative  organizations,  resulting from employee actions
and other allegations  regarding business  practices.  In management's  opinion,
there are no  outstanding  issues of this nature at May 1, 2000 that will have a
material  adverse  effect on our  consolidated  financial  position,  results of
operations, or liquidity.

Potential for Suspension or Debarment

     As a U.S.  Government  contractor,  we are  subject to federal  regulations
under  which our  ability  to receive  awards of new  government  contracts,  or
extensions of existing government  contracts,  may be unilaterally  suspended or
barred  by the U.S.  Government,  if we  should  be  convicted  of a crime or be
indicted  based on  allegations  of a  violation  of  certain  specific  federal
statutes or other activities. The initiation of suspension or debarment hearings
against us or any of our  affiliated  entities  could  have a  material  adverse
impact upon our business and prospects.

Potential for Adverse Judgments in Legal Proceedings

     DynCorp and its  subsidiaries and affiliates are involved in various claims
and lawsuits,  including  contract  disputes and claims based on  allegations of
negligence  and other  tortious  conduct.  We are also  potentially  liable  for
certain personal injury, tax, environmental, and contract dispute issues related
to the prior operations of divested businesses.

     The total  amount of damages  currently  claimed by the  claimants in these
cases is estimated to be approximately $41.0 million, including compensatory and
punitive  damages and penalties.  In most cases,  we have denied,  or believe we
have a basis to deny,  liability.  In some cases, we also have offsetting claims
against the claimants, third parties, or insurance carriers.

     We believe  that any amounts  that will  actually be recovered by claimants
these cases will be substantially less than the aggregate amount claimed.  After
taking into account available  insurance,  we believe we are adequately reserved
with respect to the potential  liability for such claims. The estimate set forth
above does not reflect  claims that may have been incurred but have not yet been
filed.  We have recorded such damages and  penalties  that are  considered to be
probable recoveries against DynCorp or its subsidiaries. It is possible that the
level of filings will increase more than management has anticipated,  increasing
such exposures, and no upper limit of exposure can be reasonably estimated.

Competition

     The markets  that  DynCorp  serves are highly  competitive.  In each of our
businesses,  our  competition  is quite  fragmented,  with no single  competitor
holding a significant market position.  We experience vigorous  competition from
industrial firms, university laboratories,  and nonprofit institutions.  Some of
our  competitors  are  large,   diversified  firms  with  substantially  greater
financial resources and larger technical staffs than we have.

     Government agencies also compete with us, because they can utilize internal
resources to perform certain types of services that might otherwise be performed
by us. Most of our revenues are derived from contracts with the U.S.  Government
and its  prime  contractors,  and such  contracts  are  awarded  on the basis of
negotiations or competitive bids where price is a significant factor.

Company May Be Obligated to Repurchase Shares of Certain ESOP Participants

     When a participant in the DynCorp  Employee  Stock  Ownership Plan ("ESOP")
receives a distribution of common stock from the ESOP prior to the time when our
common stock becomes readily  tradable stock, the ESOP, or DynCorp under certain
circumstances,  is obligated to repurchase such shares from the participant.  To
the extent that DynCorp  repurchases those shares, our availability of cash will
be adversely affected.  DynCorp has the right under both the ESOP and applicable
law to defer  indefinitely  the  repurchase  of any  shares,  if  payment to the
stockholders would impair the capital of DynCorp. See "Employee Benefit Plans --
Employee Stock Ownership Plan -- Distributions and Withdrawals."

No Payment of Cash Dividends

     We have not paid a cash  dividend  since 1987.  We do not have a policy for
the payment of regular dividends. Any payment of dividends in the future will be
subject  to the  discretion  of our Board of  Directors  and may be  subject  to
restrictions  imposed  by  financing  arrangements  and by legal and  regulatory
restrictions.

Absence of a Public Market

     There is no present public market for our common stock,  although one could
be  established  in the future.  Our  internal  stock  market  provides the only
mechanism for selling our common stock.  There may not be sufficient  buy orders
on a trade date to support  current sell orders.  We may defer or cancel a trade
date,  either  because of an  imbalance  of buy and sell orders  which would not
permit an orderly trade or for other reasons. There can be no assurance that the
purchasers  of common stock in this offering will be able to resell their shares
through the internal stock market should they decide to do so.

     To the extent that the internal  stock  market does not provide  sufficient
liquidity for a stockholder, and the stockholder is otherwise unable to locate a
buyer for his or her shares, the stockholder's  investment could remain illiquid
for an indefinite  period, and the stockholder could effectively be subject to a
total loss of  investment.  Accordingly,  the  purchase  of our common  stock is
suitable only for persons who have no need for liquidity in this  investment and
can afford a total loss of investment.  See "Market  Information -- The Internal
Stock Market."

Right of First Refusal

     All shares of common stock  offered by this  prospectus  will be subject to
our right of first refusal to purchase such shares before they may be offered to
third  parties,  except on the  internal  stock  market.  Shares of common stock
purchased on the internal stock market will be subject to  contractual  transfer
restrictions  having the same  effect as those  contained  in the  by-laws.  See
"Description of Capital Stock -- Restrictions on Common Stock."

Offering Price Determined by Formula, Not Market Forces

     The offering price for the common stock is, and subsequent  offering prices
will  be,  determined  by  means  of the  formula  set  forth  on page 1 of this
prospectus. The formula takes into consideration our financial performance,  the
market  valuation  of  comparable  companies,  and the limited  liquidity of the
common stock,  as determined by our Board of Directors  based on an  independent
appraisal.  The  formula is subject to change by the Board of  Directors  in its
sole discretion. See "Market Information -- Determination of Purchase Price."

Anti-Takeover Effects

     The  combined  effects  of  ownership  of  a  substantial  portion  of  the
outstanding shares of common stock by management and our benefit plans, together
with our right of first refusal,  may discourage,  delay, or prevent attempts to
acquire  control of DynCorp that are not negotiated  with our Board of Directors
and the trustees of the benefit plans. These may,  individually or collectively,
have the effect of discouraging  takeover attempts that some stockholders  might
deem  to  be  in  their  best  interests,   including  tender  offers  in  which
stockholders  might  receive a premium for their  shares over the formula  price
available on the internal stock market,  as well as making it more difficult for
individual  stockholders  or a group of  stockholders  to elect  directors.  See
"Description of Capital Stock."

Dilution

     The net tangible  book value of DynCorp on December 30, 1999 was a negative
$228.1  million,  or $(33.80) per share,  which is  substantially  less than the
current  formula price of $22.75.  This is caused by the fact that the shares of
common  stock held by the  Employee  Stock  Ownership  Plan are subject to a put
option.  See  "Employee  Benefit  Plans  --  Employee  Stock  Ownership  Plan --
Distributions and Withdrawals." These shares are deemed to be redeemable and are
only treated as temporary equity.  Therefore,  purchasers of common stock in the
offering  will realize  immediate and  substantial  dilution of $56.55 per share
(249%),  or $54.93  per share  (241%)  assuming  conversion  of all  outstanding
options, and the issuance of all restricted stock shares. The amount of dilution
may vary, depending on the formula price.

     The 2,366,586 shares remaining  available for issue under our benefit plans
described below would dilute the number of shares  outstanding.  See "Securities
Offered by this  Prospectus -- Shares  Remaining for Issue under Benefit Plans."
The  Compensation  Committee also adopted a new 1999 Long-Term  Incentive  Stock
Plan,  under  which up to 800,000  additional  shares may be issued.  If all the
shares which could be issued upon the exercise of  outstanding  options and as a
result of expiration of deferrals under our former  Restricted  Stock Plan, were
to be issued,  there would be 11,989,831 shares of common stock outstanding.  As
of May 1, 2000, there were 10,413,708 shares outstanding.

                      Securities Offered by This prospectus

Common Stock Offered by DynCorp

     The shares of common  stock  offered by DynCorp may be offered  through the
internal  stock market to trustees or agents for the benefit of employees  under
our employee benefit plans described below or directly to our current and future
employees.  For purposes of our  registration  under the Securities Act of 1933,
all sales on the internal stock market,  whether direct by DynCorp, by officers,
directors,  and other  affiliates of DynCorp,  and by other  stockholders may be
attributed to us.

     Total sales to date on the internal stock market are:

     o 2,945 shares sold directly by DynCorp,

     o 182,338 shares sold by officers, directors, and affiliates of DynCorp,
       and

     o 1,164,371 shares sold by other stockholders.

     In  addition,  we have  issued  133,414  shares to  employees  through  our
employee benefit plans.

     Following these sales and issuances, 10,486,245 shares remain available for
this  offering,  of  which  4,141,369  shares  are  available  for sale by us or
issuance under our benefit plans, 2,135,876 shares are available for sale on the
internal market by our officers, directors, and affiliates, and 4,209,000 shares
may be sold by other stockholders.

Direct and Contingent Sales to Employees

     We  believe  that  our  success  is  dependent  upon the  abilities  of our
employees.  Since 1988,  we have  pursued a policy of offering  such  persons an
opportunity  to make an equity  investment in DynCorp as an inducement to become
and  remain  employees.  At the  discretion  of our  Board of  Directors  or the
Compensation  Committee  of the Board of  Directors,  and subject to  applicable
state securities laws,  employees and directors may be offered an opportunity to
purchase shares of common stock offered by this prospectus.

     All such direct and  contingent  sales to employees,  as well as directors,
will be effected through the internal stock market or the employee benefit plans
described below and may be attributable to DynCorp. Pursuant to our by-laws, all
shares of common  stock  offered by us after May 11, 1995,  to our  employees or
directors and all shares of common stock  purchased on the internal stock market
are subject to a right of first refusal.  See  "Description  of Capital Stock --
Restrictions on Common Stock."

Equity Target Ownership Policy

     We have adopted an Equity  Target  Ownership  Policy,  under which  certain
highly paid  employees  are  encouraged to invest  specified  multiples of their
annual  salaries  in shares of the common  stock  over a period of seven  years.
Under the Policy,  employees in the  Company's  three  highest  salary bands are
encouraged to invest an amount  related to their annual salary rate in shares of
common stock as follows:

                              recommended value of
Base salary rate of:          holdings:
- --------------------          ---------
President & CEO               4.0 times base salary
$300,000 or more              3.0 times base salary
$200,000 to $299,999          2.5 times base salary
less than $200,000            1.5 times base salary

     Investments  under any of the employee  benefit plans  described  below, as
well as other  shares  owned by the  employee,  will qualify for purposes of the
Policy.

     As an  incentive  to comply  with the Policy,  the Company  pays 15% of the
purchase price plus related  withholding  taxes for  individuals  subject to the
Policy who directly  purchase 250 or more shares of common stock on the internal
stock market on a single trade date.

Savings and Retirement Plan

     We maintain a Savings and Retirement Plan ("SARP"), which is intended to be
qualified  under  Sections  401(a)  and  401(k) of the  Internal  Revenue  Code.
Generally,  all employees are eligible to  participate,  except for employees of
units designated as ineligible,  such as units which are subject to the terms of
collective  bargaining  agreements,  participate in other site-specific  benefit
plans,  or are located in foreign  countries.  The SARP permits a participant to
elect to defer, for federal income tax purposes,  a portion of his or her annual
compensation and to have such amount contributed  directly by us to the deferred
fund of the SARP for his or her benefit.

     We may, but are not obligated to, make a matching  contribution to the SARP
trust for the benefit of those  participants who have elected to defer a portion
of their  compensation  for investment in shares of common stock.  The amount of
any matching  contribution is determined  periodically by our Board of Directors
based on the aggregate amounts deferred by participants.  We currently provide a
company  matching  contribution,  either in cash for purchase of common stock on
the internal stock market or in shares of common stock, of 100% of the first one
percent  of  compensation  invested  in  the  Company  common  stock  fund  by a
participant and 25% of the next four percent of compensation so invested. We may
also make  additional  contributions  to the SARP trust in order to comply  with
Section 401(k) of the Internal Revenue Code.

     Each  participant  is vested  at all  times in 100% of his or her  personal
contributions to the deferred fund accounts.  Company  contributions become 100%
vested after one year of service.  Benefits are  distributable  to a participant
over certain  specified time periods  following such  participant's  retirement,
permanent disability, death, or other termination of employment. Pursuant to our
by-laws,  shares of common stock distributed to a participant under the SARP are
subject to our right of first  refusal.  See "Employee  Benefit Plans -- Savings
and Retirement Plan" and "Description of Capital Stock -- Restrictions on Common
Stock."

Employee Stock Purchase Plan

     We have also established an Employee Stock Purchase Plan for the benefit of
substantially  all our  employees.  The Stock  Purchase  Plan  provides  for the
purchase of common stock through payroll deductions by participating  employees.
The Stock  Purchase  Plan is intended to qualify as a stock  purchase plan under
Section  423 of the  Internal  Revenue  Code.  Participants  designate a certain
amount to be withheld  from their  regular pay for the purchase of common stock,
and DynCorp  contributes an additional 15% of that amount in the form of cash or
shares of common stock for each participant.

     Purchases  on  behalf  of  participating  employees  are made  through  the
internal stock market.  All shares purchased pursuant to the Stock Purchase Plan
are  credited  to  the  participant's  directly  owned  stock  account  promptly
following  the trade  date on which they were  purchased  and,  pursuant  to our
by-laws,  are subject to our right of first refusal. See "Employee Benefit Plans
- --  Employee  Stock  Purchase  Plan"  and   "Description  of  Capital  Stock  --
Restrictions on Common Stock."

1995 Stock Option Plan

     Pursuant to our 1995 Stock Option Plan,  we have granted  stock  options to
certain  employees and directors.  As of May 1, 2000,  95,800 stock options have
been exercised and 1,083,500 are outstanding.  We do not anticipate granting any
more  options  under this Plan.  Pursuant to the  by-laws,  all shares of common
stock  issued  upon the  exercise of such stock  options  will be subject to our
right of first refusal.  See "Employee  Benefit Plans -- 1995 Stock Option Plan"
and "Description of Capital Stock -- Restrictions on Common Stock."

Executive Incentive Plan

     Our Executive  Incentive Plan provides for the payment of annual bonuses to
certain officers and executive employees.  The Executive Incentive Plan provides
for payment of up to 20% of the bonuses, net of applicable taxes, in the form of
shares of common stock, valued at the then-current  formula price. The shares of
common stock are  distributed  following  each fiscal  year.  As of May 1, 2000,
37,614 shares have been distributed under the Executive Incentive Plan. Pursuant
to our  by-laws,  shares of common stock  awarded  pursuant to this Plan will be
subject to our right of first refusal.  See "Employee Benefit Plans -- Executive
Incentive  Plan" and  "Description  of Capital Stock --  Restrictions  on Common
Stock."

Direct Purchase Plan

     Under the Direct Purchase Plan,  active  employees and directors who desire
to purchase  shares directly in their own names on the internal stock market are
permitted  to do so,  subject to  availability  of shares and  applicable  state
securities laws. Shares are purchased at the current formula price.

Employee Stock Ownership Plan

     The Employee Stock  Ownership  Plan ("ESOP") is a retirement  plan, and its
assets are not taxed under the Internal  Revenue Code until they are distributed
to  participants.  Generally,  all  employees  participate  in the ESOP,  except
employees of groups or units designated as ineligible, such as employees covered
by collective bargaining agreements.  Interests of participants in the ESOP vest
in accordance with a four-year vesting schedule. Benefits are normally allocated
to a participant in shares of common stock and are distributable  within certain
specified  time  periods  following  such  participant's  retirement,  permanent
disability, death, or other termination of employment.

     Since our common stock is not "readily tradable" as defined by the Internal
Revenue  Code,  a  participant  is entitled to a statutory  "put  option" at two
separate times  following a distribution  of shares.  Under the put option,  the
ESOP, or DynCorp if the ESOP does not do so, is obligated to purchase the shares
at the ESOP share price, as determined  upon advice from the ESOP's  appraisers.
See "Employee  Benefit Plans -- Employee Stock  Ownership Plan --  Distributions
and  Withdrawals."  In the event the  participant  declines to exercise  the put
option,  such  shares of  common  stock  may be sold by the  participant  on the
internal  stock  market,  subject to the  restrictions  and  limitations  of the
internal  stock  market.  The ESOP  share  price  paid for  these  shares  being
distributed from the ESOP is not determined by the formula,  and amounts paid to
participants at the time of  distribution  may be different from amounts paid to
sellers on the internal  stock market.  See "Market  Information -- The Internal
Stock Market."

     The amount of our annual  contribution  to the ESOP is  determined  by, and
within the  discretion of, our Board of Directors and may be in the form of cash
or common  stock.  Pursuant  to the plan  document,  any shares of common  stock
distributed  out of the ESOP  will be  subject  to a right of first  refusal  on
behalf of the ESOP and DynCorp.  See "Employee  Benefit Plans -- Employee  Stock
Ownership Plan -- Distributions and Withdrawals."

Shares Remaining for Issue under Benefit Plans

     Of the shares of common stock  initially  registered  under this prospectus
for issuance by DynCorp through our benefit plans,  the following  shares remain
available for issue:

     o  up to 850,000 shares through the Savings and Retirement Plan,

     o  up to 100,000 shares under the Employee Stock Purchase Plan,

     o  up to 1,154,200 shares through the 1995 Stock Option Plan, and

     o  up to 262,386 shares under the Executive Incentive Plan.

Common Stock Offered by Officers, Directors, and Affiliates

     This prospectus relates to the offer and sale of shares directly by certain
officers,  directors, and affiliates.  Such persons may, from time to time, sell
shares of the common  stock being  offered by this  prospectus  on the  internal
stock market,  and 182,338 shares have been sold on the internal stock market by
such persons as of May 1, 2000. The total aggregate shares  remaining  available
for offer and sale by officers,  directors, and affiliates under this prospectus
as of May 1, 2000 is 2,135,876 shares.

     While we have  registered  all shares  owned by  officers,  directors,  and
affiliates on a fully diluted basis,  including unvested options, we do not know
whether some, none, or all of such shares will be so offered or sold. We believe
that the  Executive  Target  Ownership  Policy  acts as a  disincentive  to some
officers to sell their common stock at this time. The officers,  directors,  and
affiliates   will  not  be  treated  more  favorably  than  other   stockholders
participating  as  sellers  on  the  internal  stock  market.   Like  all  other
stockholders selling shares on the internal stock market, other than DynCorp and
our benefit plans, the officers, directors, and affiliates will pay our
designated broker-dealer a commission equal to one percent of the proceeds from
their sales.  See "Market Information-- The Internal Stock Market."

     The following  table sets forth  information as of May 1, 2000 with respect
to the number of shares of common stock owned  directly or indirectly by each of
the officers,  directors,  and affiliates.  It includes shares issuable upon the
exercise of outstanding  options,  shares  issuable as a result of expiration of
deferrals under our former  Restricted  Stock Plan, and shares allocated to such
person's  accounts under our employee benefit plans, as well as their respective
percentages of ownership of equity on a fully diluted basis. Each of the persons
is a director or executive officer of DynCorp. The shares are owned of record or
beneficially.  The table also reflects the relative ownership of such persons in
the event of, and after,  their  individual  sales of all the registered  shares
owned by them in this offering.

                               Market Information


The Internal Stock Market

     In 1988,  following a decision by our Board of Directors to consider offers
for the  purchase  of DynCorp,  we became  privately  owned  through a leveraged
buy-out involving the Company's  management group.  Public trading of our common
stock ceased, and the new management installed the Employee Stock Ownership Plan
as our principal  retirement  benefit.  Approximately  31,236 current and former
employees  are now  beneficial  owners of our  common  stock  through  the ESOP,
representing  approximately  71.6% of the shares of common stock  outstanding on
May 1,  2000 and  approximately  62.1% of our  common  stock on a fully  diluted
basis.

     After  public   trading  of  our  common  stock  ceased,   our   management
stockholders and outside investors relied on a stockholders agreement as a means
of  restricting  the  distribution  and  permitting  limited sales of our common
stock. On May 10, 1995, our Board of Directors approved the establishment of the
internal  stock market as a means of trading  common stock on a regular basis to
replace the former stockholders agreement.

     The internal stock market generally permits all stockholders to sell shares
of common  stock on one trade date each  calendar  quarter,  subject to purchase
demand.  All sales of common  stock on the  internal  stock  market  are made to
active employees and the trustees or administrator of our benefit plans, who may
purchase  shares of common stock for their  respective  trusts and plans, to the
extent permitted under  applicable  state  securities  laws.  Limitations on the
number of shares that an individual  can purchase  directly may be imposed where
there are more buy orders than sell orders on a particular trade date.

     The internal stock market is managed by our wholly owned subsidiary, DynEx,
Inc. A registered  broker-dealer,  acting upon  instructions from the respective
buyers and sellers,  carries out the purchase and sale of shares on the internal
stock market. Following determination of the applicable formula price for use on
the next trade date, the  broker-dealer  advises the  stockholders  of record by
mail,  usually at least 15 days prior to the trade date, as to the amount of the
formula  price  and  the  trade  date.  The   broker-dealer   asks  whether  the
stockholders  wish to sell shares on the internal  stock market and advises them
how to  deliver  written  sell  orders  and stock  certificates.  These  must be
received at least two days prior to the trade date, to facilitate the sale. This
information  is also  provided  through our internal  communications  systems to
participants in the various benefit plans.

     We may, but are not  obligated to,  purchase  shares of common stock on the
internal  stock market on any trade date. We would only  purchase  shares if the
number of shares offered for sale by  stockholders  exceeds the number of shares
sought to be  purchased  by  authorized  buyers  and if, in our  discretion,  we
determine to make such purchases. If the number of shares sought to be purchased
exceeds the number  offered for sale,  we may, but again are not  obligated  to,
sell  sufficient  shares  to make up such  shortfall.  We will  only  enter  the
internal stock market to correct such  imbalance,  and we cannot be both a buyer
and a seller on the same trade date.

     If the aggregate  number of shares  offered for sale on the internal  stock
market is greater than the aggregate  number of shares sought to be purchased by
authorized buyers,  including DynCorp, offers to sell up to the first 500 shares
offered  by  any  seller  will  be  accepted  first.  If,  however,   there  are
insufficient  purchase orders to support the primary allocation of 500 shares of
common stock,  then the purchase  orders will be allocated  equally among all of
the proposed sellers up to the first 500 shares offered for sale by each seller.
Thereafter,  a similar  procedure  will be  applied  to the next  10,000  shares
offered by each remaining seller. If there are remaining purchase orders, offers
to sell  shares in excess of 10,500  shares  will then be accepted on a pro-rata
basis determined by dividing the total number of shares remaining under purchase
orders by the total number of shares remaining under sell orders.

     To the extent that the  aggregate  number of shares  sought to be purchased
exceeds the  aggregate  number of shares  offered for sale,  we may, but are not
obligated  to,  sell  authorized  but  unissued  shares of  common  stock on the
internal  stock market.  All sellers on the internal  stock  market,  other than
DynCorp and our benefit plans,  will pay the broker-dealer a commission equal to
one percent of the proceeds from such sales.  Purchasers  on the internal  stock
market  pay no  commission.  All  offers  and sales of common  stock made on the
internal stock market may be attributed to us.

     If the aggregate  purchase orders exceed the number of shares available for
sale, the following  prospective  purchasers  will have  priority,  in the order
listed:

     1. the administrator of the Employee Stock Purchase Plan;
     2. the trustee of the Savings and Retirement Plan;
     3. eligible employees, on a pro rata basis; and
     4. the trustees of the Employee Stock Ownership Plan.

     There is no public  market for our common  stock,  and it is not  currently
anticipated  that such a market will develop.  We established the internal stock
market in an effort to provide liquidity to our  stockholders,  but there can be
no assurance that there will be sufficient  liquidity to permit  stockholders to
resell  their  shares on the  internal  stock  market or that a regular  trading
market will  develop or be sustained  in the future.  The internal  stock market
will be dependent on the  presence of  sufficient  buyers to support sell orders
that  will be  placed  through  the  internal  stock  market.  Depending  on our
performance, potential buyers may elect not to buy on the internal stock market.
Moreover,  although we may enter the internal  stock market as a buyer of common
stock under certain  circumstances,  including an excess of sell orders over buy
orders,  we have no obligation to engage in internal stock market  transactions.
Consequently,  there is a risk that sell orders could be prorated as a result of
insufficient buyer demand or that the internal stock market may not be permitted
to open on a trade date because of the lack of buyers.

     We may defer or cancel a trade date,  either because of an imbalance of buy
and sell orders which would not permit an orderly trade or for other reasons.

     If the internal  stock market does not give a stockholder a ready means for
selling shares,  and the  stockholder is otherwise  unable to locate a buyer for
his or her shares of common stock, the stockholder  could effectively be subject
to a total loss of  investment.  Accordingly,  the  purchase of common  stock is
suitable only for persons who have no need for liquidity in this  investment and
who can afford a total  loss of  investment.  See "Risk  Factors -- Absence of a
Public Market."

Determination of Purchase Price

     The purchase price, or formula price, of the shares of common stock offered
by this  prospectus  will be determined  pursuant to the  following  formula and
valuation  process.  The  formula  price of the  common  stock,  expressed  as a
formula, is as follows:

   formula price      =       [(CF x 7)MF + NOA - IBD]
                                ---------------------
                                        ESO

     The formula  price per share of common  stock is the product of seven times
the operating cash flow (CF) for the four fiscal quarters  preceding the date on
which a price  valuation is made,  multiplied by a market factor (MF),  plus the
non-operating assets at disposition value, net of disposition costs (NOA), minus
the sum of  interest-bearing  debt  adjusted  to market  and  other  outstanding
securities  senior to common  stock  (IBD),  divided  by the number of shares of
common stock  outstanding  at the date on which a valuation is made,  on a fully
diluted basis assuming exercise of all outstanding options (ESO).

     Operating  cash  flow is the  earnings  basis  which  is  considered  to be
representative  of our  future  performance.  The basic  measurement  we use for
operating cash flow is our earnings before interest,  taxes,  depreciation,  and
amortization. Each of these elements is measured according to generally accepted
accounting principles.  Before using those objective numbers in the formula, our
Board of Directors  examines  the details  used in those  earnings to see if any
adjustments are needed in order for the earnings number to be  representative of
our future performance.  Following are examples of situations where our Board of
Directors may feel it appropriate to make  adjustments so that the earnings used
in the formula would be more representative of expected future performance:

     o  the earnings from an acquisition made late in the year may be pro-formed
        for a full year;

     o  the earnings from a  discontinued  activity may be pro-formed  out even
        though the  discontinued  activity  may not  qualify as a  discontinued
        business under generally accepted accounting principles; or

     o  a truly unusual  expenditure  or windfall  profit may be pro-formed out
        even though it is clearly part of earnings for the current year.

     The market factor is subjective. Our Board of Directors looks at the public
market pricing for other  government  service  contractors  which we believe are
comparable to us. Several other  companies are  considered,  but there is no set
number of comparable companies.  The pricing multiples of net income and of cash
flow for these  companies  are  looked  at on a  last-twelve-month  basis,  on a
fiscal-year basis, and, where available from analysts'  reports,  on a projected
basis.  Since the formula  capitalizes  our operating cash flow by a multiple of
seven,  these  comparable  companies give the Board of Directors a sense whether
the public market is currently at a higher,  lower, or roughly the same level as
that fixed multiple. The Board of Directors also looks at our earnings trends in
setting the market factor,  because the stock market generally rewards an upward
trend and punishes a downward  trend.  Our Board of Directors  will also look at
the price  earnings  multiples of  comparable  companies to see if there are any
significant changes that might influence the Board's determination of the market
factor to be used in the formula.

     If DynCorp  discontinues  a business,  and the net assets of that  business
were  recorded  as assets  held for sale,  those  assets  would be  included  in
non-operating assets at management's estimate of their disposition value, net of
disposition  costs.  The earnings  from those assets would also be excluded from
operating cash flow in the formula.  If we had a passive  investment outside our
normal operations, the earnings from that investment would also be excluded from
operating  cash flow,  and the lower of cost or estimated  market value would be
included in non-operating  assets.  Other similar  situations could give rise to
inclusion in non-operating assets, but an asset must be clearly non-operating to
be so included.

     Interest-bearing debt includes any securities senior to common stock. Under
generally  accepted  accounting  principles,  interest-bearing  debt  is  to  be
reported net of any  unamortized  discount at issuance.  However,  such issuance
discounts  are  ignored in the  formula,  and it is  expected  that debt will be
recorded at its face value. On the other hand, if it is the intent of management
to call any portion of our long-term  debt in the near term, the amount used for
that portion of interest-bearing debt would be at its call price.  Similarly, if
the debt were publicly traded at a discount,  and it was management's  intent in
the near term to retire debt  through  open  market  discounted  purchases,  the
market  price  would be used for that  portion  of the debt in the  formula.  In
applying the formula,  our Board of Directors would also look at any convertible
securities and  subjectively  decide whether it is likely that these  securities
would be  converted.  If, in the opinion of the Board,  they will be  converted,
these securities would be included in the fully diluted common shares and not as
interest-bearing  debt.  Preferred  stock, or any similar security senior to the
common stock in liquidation, would be considered as interest-bearing debt.

     The number of  equivalent  shares  outstanding  assumes the exercise of all
outstanding  options,  if no greater  than the current  formula  price,  and the
conversion of any convertible  securities,  of which none are outstanding at the
current time.

     Our Board of  Directors  reviews the formula  price,  including  the market
factor,  on a quarterly  basis,  in preparation  for internal stock market trade
dates.  The  valuation  of our common stock is reviewed in  conjunction  with an
appraisal  that  is  prepared  by  the  independent  appraiser  retained  by the
committee  administering  our  Employee  Stock  Ownership  Plan.  Our  Board  of
Directors  believes  that the valuation  process  results in a stock price which
reasonably reflects the value of DynCorp on a per-share basis. See "Risk Factors
- -- Offering Price Determined by Formula, Not Market Forces."

     Our Board of  Directors  adopted the formula in its current  form on August
15, 1995. The formula is subject to change by the Board of Directors.

Availability of Information

     We intend to disseminate  the current formula price on at least a quarterly
basis to all employees through internal communications,  including bulletins and
electronic mail messages and to other stockholders by mailed reports,  including
mailed notices of upcoming  trade dates.  Participants  in the employee  benefit
plans may obtain the  current  formula  price by  calling T. Rowe  Price's  Plan
Account Line at  1-800-922-9945  or through the Employee Benefits portion of our
web site www.dyncorp.com.

     We also  intend  to  distribute  copies  of our  audited  annual  financial
statements to all stockholders,  including record holders and beneficial owners,
and to potential  participants  in the internal  stock market  through  employee
benefit plans,  either through U.S. mail or inter-company mail. Such information
is  distributed  at  the  time  that  proxy   information  is  distributed   and
solicitations are made for voting  instructions from participants in the benefit
plans,  normally in June of each year.  We file  unaudited  quarterly  financial
information  with the SEC, and copies of such information are available from the
SEC. See "Where You Can Find More Information."

Private Transactions

     This prospectus does not apply to private transactions outside the internal
stock market. From time to time, stockholders,  including former employees, sell
shares  to us or  to  the  Employee  Stock  Ownership  Plan  trust  in  private,
unsolicited  transactions.  Sales to the trust are intended to take advantage of
the capital gain  deferral  provisions  of Section 1042 of the Internal  Revenue
Code.

                                 Use of Proceeds

     The shares of common  stock  that may be  offered  by us are being  offered
primarily to permit the  acquisition of shares by our employee  benefit plans as
described  herein and to permit us to offer  shares of common stock to employees
and  directors.  We do not intend or expect this  offering to raise  significant
capital.  Any net  proceeds  received  by us from the sale of the  common  stock
offered  will be added to our  general  funds for  working  capital  and general
corporate  purposes.  Currently,  we have no specific  plans for the use of such
proceeds.  It is  anticipated  that  stockholders,  not  DynCorp,  will make the
majority of the sales of common stock on the internal stock market, and we will
not receive any portion of the net proceeds from the sale of such shares.

- --------------------------------------------------------------------------------
                             Employee Benefit Plans

     We maintain  several  employee  benefit plans pursuant to which some of the
shares of common stock being offered by this  prospectus may be offered or sold.
The primary purpose of these plans is to motivate our employees to contribute to
our growth and  development  by  encouraging  them to achieve and surpass annual
goals of DynCorp and the operations for which they are responsible. Following is
a summary description of these plans.

SAVINGS AND RETIREMENT PLAN

Trustees

  T. Rowe Price Retirement Plan Services, Inc., P. O. Box 17215, Baltimore,
Maryland  21297-1215, serves as trustee of the Savings and Retirement Plan,
except that DynCorp serves as trustee of the DynCorp Company stock fund.

Administration

  DynCorp administers the SARP through an administrative committee consisting of
P. T. Graham, H. M. Hougen, and R. P. Kerr, employees of DynCorp, whose address
is 11710 Plaza America Drive, Reston, Virginia  20190.

Eligibility and Participation

  All  employees  are  eligible to  participate  in the SARP upon  commencing
employment,  except for employees in groups or units  designated as  ineligible,
such as employees  covered by  collective  bargaining  agreements or employed by
foreign  subsidiaries.  As of May 5, 2000, there were approximately 5,457 active
participants  in the  SARP,  of which  approximately  4,592  participate  in the
DynCorp Company stock fund.

Contributions and Allocations

  The SARP  permits a  participant  to elect to defer a portion of his or her
compensation  for the plan year and to have  such  deferred  amount  contributed
directly by DynCorp to the SARP trust for allocation to the  participant's  SARP
account.  Amounts  deferred by participants for the plan year ended December 31,
1999 totaled  approximately $17.4 million. Such deferred amounts are treated for
tax purposes as  contributions  made by DynCorp.  The  administrative  committee
determines the maximum amount of  compensation  that a participant  may elect to
defer,  but in no event may the deferral exceed $10,500 during 2000. This annual
limitation  is  periodically  adjusted for  cost-of-living  changes  under rules
prescribed by the Secretary of the Treasury.

  A participant in the SARP who has made a deferral election may terminate or
alter the rate of his or her deferrals at any time under the terms of the SARP.

  In addition to amounts  deferred  by  participants,  we may make a matching
contribution  to the SARP  accounts of those  participants  who have  elected to
defer a portion of their  compensation  equal to a percentage or  percentages of
the amounts which such participants have elected to defer. This company matching
contribution  is  determined  periodically  by our  Board  of  Directors  and is
allocated to the SARP accounts of those participants who have elected to defer a
portion of their  compensation.  However,  we are not  obligated  to make such a
contribution.

  We currently contribute a stock match of 100% of the first one percent of a
participant's  compensation  deferred  under the SARP for  investment in DynCorp
common stock and 25% of the next four percent of such  compensation so deferred.
Our stock-match contribution to the SARP could be made in shares of common stock
or in cash,  which would then be used to purchase  common  stock on the internal
stock market.  850,000 shares of common stock were reserved in 1995 for possible
issuance in  satisfaction of our  stock-match  obligations  through 2001, but we
have not issued any such shares to date.

<PAGE>

  Amounts  deferred by  participants  must be paid to the  trustee  within 15
business  days of the last day of the  calendar  month  in  which  the  deferral
occurred.  Other company  contributions to the SARP are made by the due date for
our federal income tax return for the applicable  year. Our practice has been to
make matching  company  contributions  quarterly,  based on current  participant
deferrals,  and we plan to make a stock match in kind or a contribution  of cash
to purchase common stock for the stock match in conjunction  with the applicable
trade date.

  An eligible  employee  may  transfer a rollover  contribution  from another
qualified retirement plan to the trust fund maintained for the SARP, pursuant to
applicable regulations and administrative committee procedures. Such transferred
funds may be invested in DynCorp  common  stock but are not eligible for a stock
match.

Investment of Funds

  The  administrative  committee  has  established  a  choice  of  investment
alternatives,  including  DynCorp common stock,  in which  contributions  to the
SARP,  including that portion of compensation which participants elect to defer,
may be invested.

  The investment alternatives currently available to participants in the SARP
include DynCorp common stock and 13 T. Rowe Price investment funds. Participants
may also invest in self-directed  investments  through T. Rowe Price's TradeLink
Plus  investment  account.  These T.  Rowe  Price  investment  funds  have  been
available to  participants  since  September,  1998.  Previously,  the SARP used
Merrill Lynch & Company and other publicly traded funds for investment options.

  A participant's  entire interest in his or her SARP account may be invested
in a mixture  of DynCorp  common  stock and any of the other  investment  funds.
However,  in  order  to  obtain  the  stock  match,  the  matched  portion  of a
participant's  compensation  deferred under the SARP must be invested in DynCorp
common stock that is not exchangeable for other  investment  alternatives  until
after a period of 18  months.  The stock  match  will  also be  invested  in the
DynCorp  common stock fund,  but that stock match portion of the  investment may
not be exchanged for another investment alternative.

  Participants may elect to have contributions allocated or apportioned among
the   different   investment   alternatives,   subject   to   restrictions   the
administrative committee may specify. Separate SARP accounts are established for
each investment alternative selected by a participant,  and each such account is
valued  separately.  Except for  restrictions  on  investments in DynCorp common
stock,  participants may transfer amounts from one investment alternative to one
or more other investment alternatives on a daily basis.

  Investments  in  DynCorp  common  stock,  other  than the  non-exchangeable
company  contribution  described  above,  may be exchanged into other investment
choices, subject to the 18-month limitation mentioned above, but only on a trade
date.

  All amounts  related to DynCorp  common stock are invested in common stock,
except for  accumulations  pending use at the next trade date.  At a trade date,
the monies  attributable to shares which  participants  have elected to transfer
into or out of DynCorp common stock are first netted against each other, and the
trustee then buys or sells the remaining  number of shares on the internal stock
market. If there is an insufficient  market to allow the trustee to sell all the
shares,  the  investor  may not be able  to  convert  the  shares  into  another
investment or into cash for a distribution. Accordingly, investment exchanges of
participants'  investments  that are held in  DynCorp  common  stock fund may be
restricted.  See "Risk  Factors  --  Absence  of a Public  Market"  and  "Market
Information -- The Internal Stock Market."

  The following tables summarize,  as of the dates indicated,  the investment
performance,  since  December 31, 1996, of each of the T. Rowe Price  investment
options  in which  SARP  funds  can be  invested.  The  summary  is based on the
assumption  that a  participant  made an  initial  investment  of $100.00 in the
investment fund.

DynCorp Company Stock Fund

     Because our common stock has not been publicly traded since 1988, there has
not  been  any  historical  market-determined  price.  The  prices  shown  below
represent  the formula  price for the last trade date on or  preceding  the date
shown.

     The following tables summarize,  as of the dates indicated,  the investment
performance  of DynCorp  common stock since  December  31, 1996.  The summary is
based on the assumption that a participant made an initial investment of $100.00
in the DynCorp Company stock fund.

                    Average
                   price per
                     share      Unit value     % increase

    12/31/97        $20.00         $105.26          5.3%
    12/31/98        $20.00         $105.26            0%
    12/31/99        $23.50         $123.68         17.5%
     3/31/00        $22.75         $119.74        (3.19%)

     However,   investments  in  DynCorp  common  stock  through  the  SARP  are
immediately enhanced by the applicable stock match.  Assuming that a participant
in the SARP had elected to defer 1% of salary  toward an  investment  in DynCorp
common  stock for the  November  25, 1996 trade date and that  DynCorp  made the
appropriate  100% stock  match,  an  investment  of $100.00  would have grown as
follows:

Vesting

     Each SARP  participant  is 100% vested in those portions of his or her SARP
account  which  are  attributable  to the  participant's  salary  deferrals  and
earnings  thereon.  The  stock  match  and  any  other  discretionary   employer
contributions will be fully vested after one year of service.
<PAGE>

Loans

     Loans from their SARP  accounts are  available to all  participants.  Loans
have a maximum limit of $50,000,  reduced by the participant's highest aggregate
outstanding loan balance during the preceding 12-month period. Loans are further
limited  to 50%  of a  participant's  vested  interest  in  his or her  eligible
accounts, excluding amounts invested in DynCorp common stock. Loans must:

     o   bear a reasonable rate of interest,

     o   be adequately secured,

     o   state the date upon which the loans must be repaid,  which in any event
         may not  exceed  five  years  from the date on which  the loan is made,
         unless the proceeds are used for the purchase of a principal residence,
         in which case repayment may not exceed 10 years, and

     o   be amortized with level payments made not less frequently than
         quarterly over the term of the loan.

     Active  employees' loans must be repaid through payroll  deductions.  Up to
50% of the participant's  vested account balances are security for the loan, and
the SARP has a security  lien against  those  balances.  A loan will result in a
withdrawal of the borrowed amounts from the participant's  interest in the funds
against which the loan is made.  Principal and interest payments on the loan are
allocated to the account of the borrowing  participant  in  accordance  with the
current investment choices of the participant.

Distributions and Withdrawals

     If a participant's  employment  terminates,  the participant is entitled to
receive a distribution  of his or her entire vested  interest in his or her SARP
account as soon as  practicable  following  the date of such  termination.  If a
participant  dies while  employed,  the trustee will make a distribution  of the
participant's  entire  interest in his or her SARP account to the  participant's
spouse, or, if such spouse has given proper consent or if the participant has no
spouse, to the beneficiary designated by the participant. If the participant has
suffered a  permanent  disability  while  employed by us, the trustee may make a
distribution of the participant's  entire interest in his or her SARP account to
the disabled participant.

     Except in the case of qualifying hardship,  no withdrawals may be made from
the salary deferral portion of a participant's  SARP account prior to his or her
termination of employment  unless and until he or she attains the age of 59 1/2.
In the absence of a qualified domestic relations court order to the contrary,  a
participant's  interest  in the SARP  may not be  voluntarily  or  involuntarily
assigned  or  hypothecated.   We  have   established   procedures  for  hardship
withdrawals including;

    o  definition of qualifying hardships, and

    o  requirements  for  having  first  withdrawn  all  voluntary   after-tax
       contributions  from any other  retirement plans and having received the
       maximum loans available under such plans.

     All distributions from the SARP, including  withdrawals,  are paid in cash,
except that the portion of SARP balances represented by DynCorp common stock may
be  distributed  in kind  or in  cash,  at the  participant's  election.  Shares
distributed  from the SARP are not  subject to the put option  which  applies to
shares distributed from the Employee Stock Ownership Plan. See "Employee Benefit
Plans -- Employee Stock Ownership Plan -- Distributions and Withdrawals."

     Shares  which  the  trustee  is unable  to  liquidate  in time for a timely
distribution  will be  distributed  in kind.  Shares  of  DynCorp  common  stock
distributed  in kind will be subject to our right of first  refusal in the event
that the  participant  desires to sell such  shares  other than on the  internal
stock  market.  See  "Description  of Capital  Stock --  Restrictions  on Common
Stock."

EMPLOYEE STOCK OWNERSHIP PLAN

     Our Employee Stock  Ownership Plan was established as of January 1, 1988 as
our principal retirement plan. It replaced our defined benefit pension plan that
was  terminated in November,  1988.  Following  termination of the pension plan,
approximately  $10 million of excess  pension  plan assets were rolled over into
the  ESOP for the  benefit  of ESOP  participants  who were  also  pension  plan
participants.
<PAGE>

Trustees and Administration

     The  ESOP  is  administered  by the  ESOP  committee,  consisting  of T. E.
Blanchard,  a director and former employee of DynCorp,  and C. S. Cameron, G. B.
Hammond,  and J. W.  Supina,  employees  of DynCorp or its  subsidiaries.  Their
address is 11710 Plaza America Drive, Reston, Virginia 20190. The members of the
ESOP committee also serve as trustees of the ESOP.

Eligibility and Participation

     Generally, all employees,  except groups or units designated as ineligible,
participate  in the ESOP.  As of December  31,  1999,  there were  approximately
31,236 active and terminated, vested participants in the ESOP.

Contributions, Allocations, and Forfeitures

For the plan year ended  December 31, 1999,  DynCorp  contributed  approximately
$13.2  million  to the  ESOP.  The  amount of our  contributions  to the ESOP is
determined by, and within the discretion of, our Board of Directors,  subject to
certain   limitations.   See  "General  Provisions  of  the  ESOP  and  SARP  --
Contribution  Limitations."  Our annual  contribution  to the ESOP may be in the
form of cash or  DynCorp  common  stock.  Participants  may not  make  voluntary
contributions to the ESOP. Our current  practice has been to make  contributions
quarterly.

     Company  contributions  to the  ESOP  for  each  plan  year  are  generally
allocated  to  the  accounts  of  participants  in the  ratio  which  each  such
participant's  eligible compensation bears to the total eligible compensation of
all such  participants,  except in the case of employees  covered by  collective
bargaining agreements, which may specify another allocation method. Forfeitures,
if any, of the  non-vested  portion of  terminated  participants'  accounts  are
allocated to the accounts of remaining  participants who are entitled to receive
an allocation of company  contribution,  in the ratio which each such  remaining
participant's  allocation  bore to the total  allocation  of all such  remaining
participants.

Investment of Funds

     Although  it is  generally  intended  that the  assets  of the ESOP will be
invested in DynCorp common stock, the ESOP may hold cash and liquid  investments
pending purchase of common stock and for current cash needs. The exact number of
shares of common  stock,  if any,  which may be  purchased by the trustee of the
ESOP in the future will depend on various factors,  including any  modifications
to the ESOP adopted either in response to changes or  modifications  in the laws
and regulations governing the ESOP or at the discretion of our management.

     Participants  who have attained the age of 55 and have ten or more years of
participation  are  entitled  to  receive  distributions  of a portion  of their
balances  in the ESOP for  diversification  purposes.  They can  invest the cash
proceeds of the  distribution in another  retirement plan, such as an Individual
Retirement Account.

     It is the current policy of the ESOP committee to keep all assets  invested
in DynCorp common stock,  except for estimated cash reserves which are primarily
used to provide future benefit distributions,  future investment exchanges,  and
other cash needs as determined by the ESOP committee.

Vesting

     The ESOP vesting schedule provides that a participant's  interest vests 50%
after two years of service,  75% after  three  years of service,  and 100% after
four years of service, so that each participant's  interest becomes fully vested
after the  participant is credited with four years of service.  A  participant's
interest also becomes fully vested at the time of such participant's  attainment
of the  age  of  65,  permanent  disability,  or  death  while  employed  by us,
notwithstanding  the fact that the  participant  has not yet been  credited with
four years of service.
<PAGE>

Distributions and Withdrawals

     A participant will normally commence  receiving  distributions of shares of
common stock from the ESOP after he or she retires, dies, becomes disabled while
employed,  has otherwise been separated from  employment for five plan years, or
is  scheduled  to  receive  a  diversification   distribution.  In  some  cases,
distributions may commence earlier. When distributions  commence before the time
that the common stock has become  "readily  tradable"  stock,  as defined in the
Internal   Revenue  Code,  the  ESOP  or  DynCorp  is  obligated  to  repurchase
distributed  shares of common stock.  This "put option" gives the holder of such
shares  the  right to  require  the ESOP or, if the ESOP does not honor the put,
DynCorp,  to  purchase  all or a portion of such  shares at the ESOP share price
during two limited time periods.

     The  first of these  put  option  periods  is at the  time the  shares  are
initially distributed to the participant. The second period is the 60-day period
following the  beginning of the plan year  commencing  after such  distribution,
subject  to  notification  by the ESOP of the  current  valuation  of the common
stock. These shares will also be subject to a right of first refusal by the ESOP
and a subsequent right of first refusal by DynCorp if the participant desires to
sell such shares other than on the internal stock market.

See "Description of Capital Stock-- Restrictions on Common Stock."

     The ESOP  share  price is  actually  two  different  prices.  One  price is
applicable to the shares first  acquired by the ESOP in 1988,  incidental to the
leveraged  buy-out,  which constituted a controlling  portion of the outstanding
common  stock of DynCorp.  These  shares have an  "enterprise  value"  which was
$27.50 per share as of the December 31, 1999  valuation  determined  by the ESOP
committee, upon the advice of its independent appraisal firm. The other price is
applicable to shares acquired by the ESOP  subsequent to 1988,  which carried no
such controlling  factor.  These shares have a "minority value" which was $22.75
per share as of the  December 31, 1999  valuation.  Each  participant's  account
tracks the number of enterprise value shares and minority value shares allocated
to his or her account and distributable at any given time, and distributions are
made pro rata  from the two  types of  shares.  If a share is put to the ESOP or
DynCorp pursuant to the put option,  the applicable ESOP share price,  depending
upon whether  such shares  bears an  enterprise  value or a minority  value,  is
payable for the share.

     We estimate an aggregate  annual  commitment to repurchase  shares from the
ESOP participants as follows: $8.4 million in 2000, $12.6 million in 2001, $15.1
million in 2002,  $17.0  million  in 2003,  $22.6  million  in 2004,  and $107.2
million  thereafter.  To the extent that DynCorp repurchases shares as described
above,  our  ability to purchase  shares on the  internal  stock  market will be
adversely affected.  See "Risk Factors -- Company May be Obligated to Repurchase
Shares of Certain ESOP Participants."

     A participant may withdraw up to 25% of his or her aggregate vested account
after  age 55 and  ten  years  of  participation,  in  order  to  diversify  the
investment of his or her retirement  fund account.  At the sixth year after this
event occurs, the amount which may be withdrawn increases to 50%. This is called
a diversification distribution.

     Except  for the  diversification  distribution,  participants  can not make
withdrawals under the ESOP prior to termination of employment. In the absence of
a qualified domestic relations order to the contrary,  a participant's  interest
in the ESOP may not be voluntarily or  involuntarily  assigned or  hypothecated.
Any  permitted  designee  will be  subject  to the same  rules  and  limitations
applicable to the participant.

GENERAL PROVISIONS OF THE ESOP AND SARP

     The following provisions are applicable to each of the ESOP and SARP.

Contribution Limitations

     The maximum  contribution for any plan year which we may make to both plans
for the  benefit  of a  participant,  including  contributions  to the SARP as a
result of salary deferral elections by participants,  plus forfeitures,  may not
exceed the lesser of (1) $30,000 or (2) 25% of the participant's compensation.

Administration

     The  plans  are  administered,  respectively,  by the  SARP  administrative
committee  and the ESOP  committee,  whose members are appointed by and serve at
the discretion of our Board of Directors.  The members of the committees who are
currently  employed by DynCorp or its subsidiaries  receive no compensation from
the plans for services rendered in connection therewith.
<PAGE>

     The committees  have the power to supervise  administration  and control of
each plan's operations including the power and authority to:

     o allocate fiduciary responsibilities, other than trustee responsibilities,
       among the named fiduciaries,

     o designate agents to carry out responsibilities relating to the plan,
       other than fiduciary responsibilities,

     o employ legal, actuarial, medical, accounting, programming, and other
       assistance as the committee may deem appropriate in carrying out the
       plan,

     o establish rules and regulations for the conduct of the committee's
       business and the administration of the plan,

     o administer,  interpret,  construe,  and  apply  the plan and  determine
       questions relating to the eligibility,  the amount of any participant's
       service,  and the  amount  of  benefits  to which  any  participant  or
       beneficiary is entitled,

     o determine the manner in which plan assets are disbursed, and

     o direct the trustee regarding investment of plan assets,  subject to the
       directions of participants when provided for in the plans.

Pass-Through Voting and Tendering of Common Stock

     Each participant in the plans is a "named fiduciary" under the plan and has
the right to instruct the trustee on a confidential  basis on how to vote shares
of common  stock held in the  participant's  account.  The trustee will vote all
allocated  shares  held in the  plans  for  which  no  voting  instructions  are
received,  together  with all  unallocated  shares held in the ESOP, in the same
proportion  as the allocated  shares in each plan for which voting  instructions
have been received are voted. The committees are required to notify participants
of their pass-through voting rights prior to each meeting of stockholders.

     In the  event of a tender or  exchange  offer for our  common  stock,  each
participant in the plans has the right to instruct the trustee on a confidential
basis whether or not to tender or exchange his or her proportionate  interest in
the shares of common  stock held in the  various  plans.  The  trustee  will not
tender or exchange any  allocated  shares with respect to which no  instructions
are received from participants. Shares held in the plans which have not yet been
allocated to the accounts of  participants  will be tendered or exchanged by the
trustee, on a plan-by-plan basis, in the same proportion as the allocated shares
held in each plan are tendered or exchanged.

     The fiduciary  provisions of the Employee Retirement Income Security Act of
1974 govern the trustee's  duties with respect to voting and tendering of common
stock. These fiduciary provisions may require, in certain limited circumstances,
that the trustee  override the  participants'  voting  instructions or decisions
whether or not to tender shares and  determine,  in the trustee's best judgment,
how to vote the shares or whether or not to tender the shares.

Trustee

     Generally,  the  trustee  has all  the  rights  afforded  a  trustee  under
applicable law,  although the trustee generally may exercise those rights at the
direction of the respective committee.  Subject to this limitation and those set
forth in the plans and master trust agreement, the trustee's rights include, but
are not limited to, the right to:

     o   invest  and  reinvest  the  funds  held  in  the  plan's  trust  in any
         investment of any kind,  including  qualifying  employer securities and
         qualifying  employer real property as such  investments  are defined in
         the Employee  Retirement  Income Security Act, and contracts  issued by
         insurance  companies,  including  contracts  under which the  insurance
         company holds plan assets in a separate account or commingles  separate
         accounts managed by the insurance company,

     o   retain or sell the securities and other property held in the plan's
         trust,

     o   consent or participate in any reorganization or merger in regard to any
         corporation whose securities are held in the plan's trust,  subject, in
         the case of our securities,  to the participants'  pass-through  voting
         rights and right to  instruct  the  trustee in the event of a tender or
         exchange offer,  and to pay calls or assessments  imposed on the holder
         or the securities,

     o   consent to any  contract,  lease,  mortgage,  purchase,  or sale of any
         property between a corporation  whose securities are held in the plan's
         trust and any other parties,

     o   exercise  all the  rights  of the  holder of any  security  held in the
         plan's trust, including the right to vote such securities,  subject, in
         the case of our securities,  to the participants'  pass-through  voting
         rights,   convert  such  securities  into  other  securities,   acquire
         additional  securities and exchange such  securities,  subject,  in the
         case of our  securities,  to the  participants'  right to instruct  the
         trustee in the event of a tender or exchange offer, and

     o   vote  proxies  and  exercise  any other  similar  rights of  ownership,
         subject to the committee's right to instruct the trustee on how, or the
         method of  determining  how, the proxies should be voted or such rights
         should be exercised.

     The trustee's compensation and  other expenses incurred in the
establishment,  administration,  and  operation  of the  plans  are borne by the
respective trusts, unless DynCorp elects to pay such expenses.
<PAGE>

Administrative and Custodial Services

     Commercial service providers perform administrative services for the plans,
principally related to accounting,  valuation,  and recordkeeping.  The costs of
these administrative services are borne by the trusts.

Account Statements

     Each  participant  is furnished  with a statement of his or her accounts in
the respective plans, no less than annually.

Amendment and Termination

     We have  reserved  the right to amend each of the plans at any time and for
any reason, except that no such amendment may have the effect of:

     o   generally  causing  any  assets  of the plan  trusts  to be used for or
         diverted to any purposes other than providing  benefits to participants
         and their  beneficiaries and defraying expenses of the plans, except as
         permitted by applicable law,

     o   depriving any  participant or beneficiary,  on a retroactive  basis, of
         any  benefit  to  which  they  would  otherwise  be  entitled  had  the
         participant's employment terminated immediately prior to the amendment,
         or

     o   increasing the liabilities or responsibilities of a trustee or an
         investment manager without its written consent.

     We have  retained the right to  terminate  any of the plans at any time and
for any reason.  In addition,  we may  discontinue  contributions  to the plans;
provided,  however, that discontinuation of contributions will not automatically
terminate the plans as to funds and assets then held by the trustee.

Employee Retirement Income Security Act

     Each of the plans is subject to the Employee Retirement Income Security Act
of 1974,  including reporting and disclosure  obligations,  fiduciary standards,
and  prohibited  transaction  rules.  Since  each of the plans is an  individual
account plan under the Employee  Retirement  Income Security Act, neither of the
plans is subject to the jurisdiction of the Pension Benefit Guaranty Corporation
under Title IV of the Employee  Retirement  Income  Security Act, and the plans'
benefits are not guaranteed by the Pension Benefit Guaranty Corporation.

Federal Income Tax Consequences

     In our  view,  the  following  discussion  includes  a  description  of all
material  federal income tax  considerations  relating to the plans. We have not
received an opinion of counsel with respect to this discussion.

     Each of the plans is intended to be qualified  under Section  401(a) of the
Internal  Revenue Code.  Qualification  of the plans under Section 401(a) of the
Internal Revenue Code has the federal income tax consequences described below.

     A  participant  will  not be  subject  to  federal  income  tax on  company
contributions  to  the  plans  at  the  time  such  contributions  are  made.  A
participant  will  not be  subject  to  federal  income  tax on  any  income  or
appreciation  with respect to the  participant's  accounts under the plans until
distributions are made or deemed to be made to the participant.

     Neither a  participant  nor DynCorp  will be subject to federal  employment
taxes on  company  contributions  to the plans,  except as set forth  below with
respect to certain company  contributions  to the SARP. The plan trusts will not
be subject to federal income tax on the contributions by DynCorp and will not be
subject to federal income tax on any of their income or realized gains, assuming
that the plans do not realize any unrelated-business taxable income.
<PAGE>

     Subject to  statutory  contribution  limitations,  DynCorp  will be able to
deduct the amounts that it contributes under the plans as compensation  expense,
with  the  amount  of  such  deduction  generally  equaling  the  amount  of the
contributions.

     Distributions  from the plans will be  subject to federal  income tax under
special,  complex rules that apply generally to distributions from tax-qualified
retirement  plans.  In  general,  a  distribution  from any of the plans will be
taxable in the year of receipt at  ordinary  income  rates on the full amount of
the  distribution,  exclusive of the amount of the distribution  attributable to
the participant's  after-tax  contributions made to those plans which previously
permitted such contributions, unless the participant:

     o   is  eligible  for and  elects  to roll over the  portion  of his or her
         distribution  that  is  an  "eligible  rollover   distribution"  to  an
         Individual  Retirement  Account,  other  than a Roth  IRA,  or  another
         qualified plan,

     o   receives a distribution that is a "lump-sum distribution" and elects to
         utilize ten-year  averaging,  five-year  averaging,  or partial capital
         gains taxation of the distribution, or

     o   receives common stock as part of his or her  distribution and elects to
         defer the tax on "net unrealized appreciation" of the common stock.

These special tax rules are described below.

     However, if a participant receives an in-service distribution of his or her
account balance under any of the plans, i.e., a withdrawal,  the distribution is
first considered a return of the participant's after-tax contributions,  if any,
made before 1987,  and to that extent will not be subject to federal income tax.
Next,  an  in-service  distribution  is  treated  as a pro  rata  return  of the
participant's post-1986 after-tax contributions and earnings attributable to all
the participant's  after-tax  contributions,  and to the extent  attributable to
after-tax  contributions,  the distribution will not be taxable.  The balance of
such   distribution  will  be  fully  taxable  as  ordinary  income  unless  the
participant  is eligible  for,  and elects to use,  any of the special tax rules
described below.

     Special  rules  apply to any  annuity  distributions  made under any of the
plans.

     Eligible Rollover Distributions.  In general, an "eligible rollover
distribution" is all or a portion of any distribution, including a withdrawal
or a lump-sum distribution, from any of the plans except:

     o   any  distribution  that  is  one of a  series  of  substantially  equal
         periodic payments, not less frequently than annually, made over (1) the
         participant's  life, or the joint lives of the  participant  and his or
         her beneficiary,  (2) the participant's  life expectancy,  or the joint
         life expectancies of the participant and his or her beneficiary, or (3)
         a specified period of at least ten years,

     o   any distribution required to be made because of the participant's
         attainment of age 70 1/2, or

     o   any distribution to the extent that it consists of after-tax
         contributions.
<PAGE>

     A participant  can choose a direct rollover of all or any portion of his or
her  distribution  from one of the plans that qualifies as an eligible  rollover
distribution.  In a direct rollover,  the eligible rollover distribution is paid
directly  from  the  plan to an  Individual  Retirement  Account  or to  another
qualified  plan  that  accepts  rollovers.  If a  participant  chooses  a direct
rollover,  he or she is not  taxed  on his or her  distribution  until he or she
later takes it out of the Individual  Retirement  Account or the other qualified
plan.

     If an eligible  rollover  distribution is not directly rolled over from one
of the plans to an Individual  Retirement  Account or to another  qualified plan
and is,  instead,  paid to the  participant,  it is  subject  to  mandatory  20%
withholding  for  income  taxes.  The  distribution  is  taxed  in the  year the
participant  receives it unless,  within 60 days of receipt of the distribution,
the participant rolls it over to an Individual  Retirement Account or to another
qualified plan. The portion of the distribution  that is rolled over will not be
taxed until the participant takes it out of the Individual Retirement Account or
the other  qualified  plan. If the  participant  does not roll the  distribution
over, special tax rules may apply, as described below.

     A participant can roll over up to 100% of an eligible rollover distribution
paid  directly  to him or her,  including  an  amount  equal to the 20% that was
withheld for income taxes. If the  participant  chooses to roll over 100% of the
distribution,  he or she must use other money to  contribute  to the  Individual
Retirement  Account  or the other  qualified  plan to  replace  the 20% that was
withheld from the distribution.  If the participant rolls over only the 80% that
he or she received,  the participant  will be taxed on the 20% that was withheld
for income taxes but was not rolled over.

     Lump-Sum  Distributions.  A "lump-sum distribution" is a payment within one
taxable year of a  participant's  entire account  balance under one of the plans
that is payable  because  the  participant  has  attained  age 59 1/2 or died or
otherwise separated from service. In addition,  the distribution will qualify as
a lump-sum  distribution  only if the participant  has  participated in the plan
making the  distribution  for at least five years. The special tax treatment for
lump-sum distributions is described below.

     Under five-year  averaging,  a participant may make a one-time  election to
calculate the tax on a lump-sum  distribution  by using  "five-year  averaging".
Five-year  averaging often reduces the tax a participant  owes because it treats
the distribution  much as if it were paid over five years. A participant may not
elect to use five-year averaging with respect to any distribution received after
1999.

     Under ten-year averaging,  a participant who attained age 50 before January
1,  1986  may  make a  one-time  election  to  calculate  the tax on a  lump-sum
distribution by using  "ten-year  averaging" at 1986 rates and may elect to have
the pre-1974  portion of the lump-sum  distribution  taxed at 1986 capital gains
rates. Like the five-year averaging rules,  ten-year averaging often reduces the
tax a participant owes with respect to a distribution.

     The special five-year or ten-year averaging  treatment,  as well as partial
capital gains treatment,  of lump-sum  distributions is applicable to a lump-sum
distribution  from a plan only if all other lump-sum  distributions,  whether or
not from the same  plan or plans of a similar  type,  received  during  the same
taxable year by the participant are treated in the same manner. So, for example,
if a participant receives a lump-sum  distribution from the SARP and ESOP in the
same  taxable  year,  he or she  could not elect to use  five-year  or  ten-year
averaging on the SARP  distribution  while  electing a rollover to an Individual
Retirement Account of the distribution from the ESOP.

     If a participant  receives a lump-sum  distribution  that  includes  common
stock,  he or she also may be eligible to use the special rule  relating to "net
unrealized appreciation" described below.

     Distributions  of Common Stock.  There is a special rule for a distribution
from any of the plans that includes  shares of common stock. To use this special
rule, (1) the distribution must qualify as a lump-sum distribution, as described
above, or would qualify except that the participant does not yet have five years

<PAGE>

of  participation  in  the  plan,  or  (2)  the  common  stock  included  in the
distribution must be attributable to the participant's after-tax  contributions,
if any, to the plan.  Under this  special  rule,  the  participant  may have the
option of not paying tax on the net unrealized  appreciation of the common stock
until he or she sells or  otherwise  disposes of the shares of common stock in a
taxable transaction.  Net unrealized  appreciation  generally is the increase in
the value of the common stock while it was held by the plan. Upon disposition of
the common stock in a subsequent taxable transaction, the gain realized, if any,
may be eligible for capital gains treatment. Because the rules governing the tax
treatment of capital gains and losses,  and their  application to  tax-qualified
plans, are complex and subject to change,  participants should consult their tax
advisors.

     A  participant  may instead elect not to have the special rule apply to the
net unrealized appreciation.  In this case, the net unrealized appreciation will
be taxed in the year the participant receives the shares of common stock, unless
he  or  she  rolls  over  the  common  stock,   including  the  net   unrealized
appreciation,  to an Individual  Retirement  Account or another  qualified plan.
However,  if the  participant  rolls  over the  common  stock  to an  Individual
Retirement  Account,  the special rule for net unrealized  appreciation does not
apply  when the  common  stock is  distributed  from the  Individual  Retirement
Account.

     "Early"  distributions  from the plans  will  result in an  additional  10%
excise tax on the taxable portion of the distributions, except to the extent the
distribution (1) is rolled over into an Individual  Retirement  Account or other
qualified  plan  or  (2)  is  used  for  deductible  medical  expenses.  "Early"
distributions are distributions  made prior to the date the participant  attains
age 59 1/2 unless:

     o   due to permanent disability of the participant,

     o   made to a beneficiary or an alternate payee under a qualified domestic
         relations order, or

     o   made to a participant who terminated employment during or after the
         calendar year the participant attained the age of 55.

     In  general,  the rules  summarized  above that apply to  distributions  to
participants  also apply to distributions to surviving  spouses of employees and
to  spouses or former  spouses  who are  "alternate  payees"  under a  qualified
domestic  relations  order.  A qualified  domestic  relations  order is an order
issued by a court,  usually in  connection  with a divorce or legal  separation.
Some of the  rules  summarized  above  also  apply to a  deceased  participant's
beneficiary  who is  not a  spouse.  However,  there  are  some  exceptions  for
distributions to surviving  spouses,  alternate  payees and other  beneficiaries
that should be mentioned.

     If a surviving  spouse or an alternate payee receives an eligible  rollover
distribution  from  any of the  plans,  he or she has the  same  choices  as the
participant with respect to the distribution, except that a surviving spouse may
roll over the distribution only to an Individual  Retirement Account, and not to
another qualified plan. A beneficiary other than a surviving spouse may not roll
over any distribution from any of the plans.

     A surviving spouse, an alternate payee, or another  beneficiary may be able
to use the special tax treatment for lump-sum distributions and the special rule
for  distributions  that include common stock, as described above. A beneficiary
who receives a distribution  from one of the plans because of the  participant's
death may be able to treat the  distribution  as a lump-sum  distribution if the
participant met the appropriate age requirements, whether or not the participant
had five years of participation in the plan.

     A  participant's  account  balances under all the plans must be included in
the gross estate of a  participant  for federal  estate tax purposes upon his or
her death. If the distributee is the participant's  spouse, to the extent of the
amount  included  in  the  participant's  gross  estate,  an  unlimited  marital
deduction may be available.
<PAGE>

     In addition to the federal income tax consequences applicable to all of the
plans,  the  deferred  fund of the SARP is intended  to be a qualified  "cash or
deferred  arrangement"  under  Section  401(k) of the Internal  Revenue  Code. A
participant in the SARP who elects to defer a portion of his or her compensation
and have DynCorp contribute it to the SARP will not be subject to federal income
tax on the amounts  contributed at the time the contributions are made. However,
these contributions will be subject to social security taxes and certain federal
unemployment  taxes.  Elective  deferrals  by a  participant  to his or her SARP
account is limited to $7,000 annually (adjusted for cost-of-living). This annual
limit applies on an employee-by-employee  basis to all 401(k) plans in which the
employee  participates,  including plans of other  employers.  For calendar year
2000, the adjusted limit is $10,500.

     Generally,  we will be able to deduct the amounts that we contribute to the
SARP pursuant to employee elections to defer a portion of their compensation, as
well as any  matching  or  additional  company  contributions  it  makes  to the
deferred fund. The deduction will be equal to the amount of contributions made.

     With respect to loans from the SARP commencing after December 31, 1986, any
interest  paid by the  participant  will not be  deductible,  regardless  of the
purpose of the loan or use of the loan proceeds.  Moreover, interest paid on any
loan from any of the plans by a "key employee",  as defined in Section 416(i) of
the Internal Revenue Code, will not be deductible.

     Participants  should  consult  their own tax  advisors  with respect to all
federal,  state, and local tax effects of participation in the plans.  Moreover,
we do not  represent  that the  foregoing  tax  consequences  will  apply to any
particular participant's specific circumstances or will continue to apply in the
future,  and we make no undertaking to maintain the tax-qualified  status of the
plans under Section 401(a) of the Internal Revenue Code.

EMPLOYEE STOCK PURCHASE PLAN

General

     The Employee Stock Purchase Plan was adopted on May 10, 1995, and it became
effective  July 1, 1995.  The Stock  Purchase  Plan is  intended to qualify as a
stock purchase plan under Section 423(b) of the Internal Revenue Code. The Stock
Purchase  Plan  provides  for the  purchase  of  common  stock by  participating
employees through voluntary  payroll  deductions.  At each trade date, the Stock
Purchase Plan will purchase for the account of each  participant  that number of
shares of DynCorp common stock which may be acquired with the funds available in
the  participant's  stock  purchase  account,  together  with  our  contribution
described  below.  The  Stock  Purchase  Plan  is not  subject  to the  Employee
Retirement Income Security Act.

Eligibility

     Generally,  all of our employees are eligible to  participate  in the Stock
Purchase  Plan.  However,  no employee who owned capital stock of DynCorp having
more than five percent of the voting  power or value of the capital  stock would
be able to  participate.  An employee's  eligibility to participate in the Stock
Purchase Plan will terminate immediately upon termination of employment.

     Employees  may  participate  in the Stock  Purchase  Plan by  completing  a
payroll  deduction  authorization  and establishing a brokerage account with the
broker-dealer  handling the internal stock market. The minimum payroll deduction
allowed  is $7.00 per  week,  and the  maximum  deduction  is $450 per week.  No
employee is entitled to purchase an  aggregate  amount of common  stock having a
value,  measured as of its purchase  date,  in excess of $25,000 in any calendar
year pursuant to the Stock  Purchase Plan and any other  employee stock purchase
plan that may be adopted by DynCorp.

Purchase of Shares/Discount

     Shares of common  stock  purchased  under the Stock  Purchase  Plan will be
acquired on the internal stock market.  See "Market  Information -- The Internal

<PAGE>

Stock  Market."  The amount of the payroll  deductions  will be used to purchase
shares  at a  discount  established  from  time  to  time  by  the  Compensation
Committee, not to exceed 15% of the prevailing formula price. DynCorp may either
pay the  discount  portion  to the  Stock  Purchase  Plan in cash or  deliver  a
sufficient number of shares having a value equal on the applicable trade date to
the aggregate amount of the discount. The Compensation Committee has established
the current discount rate at 15%. A total of 100,000 shares was reserved in 1995
for possible  issuance  under the Stock  Purchase Plan in  satisfaction  of this
contribution obligation, but we have not issued any such shares to date.

Distribution, Withdrawals, and Sales

     Shares of common  stock  acquired  under  the Stock  Purchase  Plan will be
allocated  to  each  participant's   individual  ownership  account  immediately
following the trade date in which the acquisition occurred. These shares may not
be sold until the  participant  has owned  them for at least one year.  However,
within 45 days  following  termination  of a  participant's  employment  for any
reason,  we may in our sole discretion  purchase the shares from the participant
or his or her estate or legal  representatives at the most recent formula price.
If required by  applicable  state  securities  laws and if the initial  purchase
price were higher than the most recent formula  price,  we would have to pay the
amount of the initial purchase price for the shares.

     Pursuant to the by-laws,  all shares of common stock purchased  pursuant to
the Stock  Purchase  Plan will be subject  to our right of first  refusal in the
event  that the  participant  desires  to sell  such  shares  other  than on the
internal stock market.  See  "Description  of Capital Stock --  Restrictions  on
Common Stock."

     Participants  may withdraw the money held in their stock purchase  accounts
at any time prior to its use to purchase  shares of common stock,  although upon
doing so the  participant  will not be  eligible  to  participate  in the  Stock
Purchase Plan until three months after such withdrawal. No interest will be paid
on the money held in the stock purchase accounts of the participants.

Amendment and Termination

     The Board of Directors may suspend or amend the Stock  Purchase Plan in any
respect, except that no amendment may:

     o  increase the maximum number of shares authorized to be issued under the
        Plan,

     o  increase our contribution for each share purchased above 15% of the
        applicable purchase price for such share,

     o  cause the Stock Purchase Plan to fail to qualify under Section 423 of
        the Internal Revenue Code, or

     o  deny to participating  employees the right at any time to withdraw from
        the Stock Purchase Plan and obtain all amounts then due to their credit
        in their stock purchase accounts.

     The Stock  Purchase  Plan will  terminate  on  December  31,  2004,  unless
extended by the Board of Directors.

Administration

     A commercial  service  provider  performs  administrative  services for the
Stock Purchase Plan,  principally  related to accounting and recordkeeping.  The
costs of these administrative services are borne by DynCorp.

Federal Income Tax Consequences

     In our  view,  the  following  discussion  includes  a  description  of all
material federal income tax considerations  relating to the Stock Purchase Plan.
We have not received an opinion of counsel with respect to this discussion.
<PAGE>

     For federal  income tax purposes,  a participant in the Stock Purchase Plan
will  recognize  no  taxable  income  until  the  taxable  year of sale or other
disposition  of the shares of common  stock  acquired  under the Stock  Purchase
Plan.

     When the shares are disposed of by a participant  more than two years after
the  date  the  shares  were  purchased  for  the  participant's   account,  the
participant  must recognize  ordinary income for the taxable year of disposition
to the extent of the lesser of:

     o  the "discount", which is the excess of the fair market value of the
        shares on the purchase date over the amount of the purchase price paid
        by the participant, or

     o  the amount by which the fair market value of the shares at disposition
        or death exceeds the purchase price.

     In addition, a participant  generally will recognize long-term capital gain
equal to the excess,  if any, of the proceeds from the disposition  over the sum
of the purchase price paid by the  participant  for the shares and the amount of
ordinary income the participant recognizes.  If the proceeds from disposition of
the  shares  are less  than the  purchase  price  paid by the  participant,  the
participant  generally  will be  entitled to a capital  loss.  In the event of a
participant's  death while owning shares acquired under the Stock Purchase Plan,
ordinary income must be recognized in the year of death in the amount  specified
in the first sentence of this paragraph.

     When the shares are  disposed of prior to the  expiration  of the  two-year
holding period,  a "disqualifying  disposition",  the participant must recognize
ordinary  income in the amount of the discount,  even if the  disposition  is by
gift or is at a loss. In addition,  the participant will generally recognize (1)
capital gains equal to the excess,  if any, of the proceeds from the disposition
over the fair market  value of the shares on the purchase  date,  or (2) capital
loss equal to the excess,  if any, of the fair market  value of the shares as of
the purchase date over the proceeds from the disposition of the shares.

     The tax treatment and tax rate applicable to any capital gain a participant
recognizes from the disposition of shares acquired under the Stock Purchase Plan
depends on the length of time the participant has held the shares, the amount of
the participant's  other income during the year, and other factors.  In general,
as of the  date of this  prospectus,  the  maximum  tax rate  applicable  to any
capital  gain  arising from a  participant's  disposition  of these shares is 20
percent in the case of shares held for more than one year,  and 39.6  percent in
the case of shares held for one year or less. For years beginning after December
31,  2000,  reduced  maximum  rates may apply with  respect to any capital  gain
recognized from the disposition of shares that, under special rules, are treated
as having  been  acquired  after  December  31, 2000 and held for more than five
years.

     The deduction of any capital loss you may recognize from the disposition of
shares  acquired  under the Stock  Purchase  Plan are  subject  to  limitations.
Because the rules  governing  the tax  treatment of capital gains and losses are
complex and subject to change, participants should consult their tax advisors.

     Participants  should  consult  their own tax  advisors  with respect to all
federal,  state,  and local tax effects of  participation  in the Stock Purchase
Plan.  Moreover,  we do not represent that the foregoing tax  consequences  will
apply to any participant's  specific  circumstances or will continue to apply in
the future. We make no undertaking to maintain the qualified status of the Stock
Purchase Plan under Section 423 of the Internal Revenue Code.

1995 STOCK OPTION PLAN

General

     Our Board of Directors  approved the 1995 Stock Option Plan on February 10,
1995,  and it  became  effective  July 1,  1995.  The  1995  Stock  Option  Plan
authorized  the  granting  of stock  options  with  respect to an  aggregate  of
<PAGE>


1,250,000  shares of common  stock,  during the period July 1, 1995 through June
30,  2000.  As of May 1, 2000,  95,800  such  options  have been  exercised  and
1,083,500 are outstanding. Substantially all of the authorized options have been
granted  at this  time,  and we do not  anticipate  the grant of any  additional
options under the Stock Option Plan.

     The  exercise  price of  options  granted  under the Stock  Option  Plan is
determined  by the  Compensation  Committee and may not be less than 100% of the
most recent formula price of the common stock on the date of grant.

     All options granted pursuant to the Stock Option Plan are  non-transferable
except by will or the laws of intestate succession.

Eligibility and Participation

     The persons eligible to receive options under the Stock Option Plan are key
employees designated by the Compensation Committee and directors.

Vesting of Options

     The right to  exercise  options  granted  prior to March 5, 1998  under the
Stock Option Plan vest at the rate of 20% per year during the  five-year  period
following the date of the grant.  The right to exercise  options  granted on and
after  such date vest at the rate of 25% per year  during the  four-year  period
following the date of the grant. All options granted prior to March 5, 1998 will
expire seven years after the date of grant  unless  earlier  exercised;  options
granted on or after such date, if  unexercised,  will expire ten years after the
date of grant.

     In the event of a change of control  involving  DynCorp,  all options  vest
immediately and may be exercised  within 30 days,  unless they are replaced with
options of an equal or greater value.

Exercise of Options

     If an optionee's  employment  terminates as a result of death,  all options
vest and may be  exercised  by the  employee's  estate  or legal  representative
during the  six-month  period  following  death.  If the employee  terminates by
reason of  disability  or retires  before age 65, all  options  vested as of the
termination  date  may  be  exercised  during  the  six-month  period  following
termination or retirement.  If an option retires at or after age 65, all options
become  vested at the date of retirement  and may be exercised  within one year.
Upon termination of employment for any other reason, all options, whether or not
vested,  will  terminate,   unless  otherwise  authorized  by  the  Compensation
Committee, which may authorize the employee to exercise vested options within 30
days.

     Upon the exercise of an option, the exercise price is payable in cash or in
shares of common stock valued at the formula price on the date of exercise.  Any
withholding  required  as a result  of the  exercise  of an option  may,  at the
discretion of the Compensation  Committee, be satisfied by withholding shares of
common stock valued at the formula price on the date of exercise.

Amendment and Termination

     The Stock  Option Plan will  terminate,  and all  unexercised  options will
expire ten years after the grant of the last  option.  No options may be granted
under the Stock Option Plan after June 30, 2000.

     The Stock Option Plan may be amended,  terminated,  or revised by the Board
of Directors,  except that no such amendment may impair any  previously  granted
option without the consent of the holders of outstanding options.

General Provisions

     All shares issued upon  exercise of options  granted under the Stock Option
Plan are  subject  to (1) our  right  of first  refusal  in the  event  that the
optionee  desires to sell his or her shares  other  than on the  internal  stock

<PAGE>

market  and (2) our  right of  repurchase  upon  termination  of the  optionee's
employment or affiliation.  See "Description of Capital Stock -- Restrictions on
Common Stock."

     If the  outstanding  shares of common  stock of DynCorp are changed into or
exchanged  for a  different  number  or kind of  shares  or  securities  through
reorganization,   merger,   recapitalization,    reclassification   or   similar
transaction,  or if the number of outstanding  shares is changed through a stock
split,  stock  dividend,  stock  consolidation,   or  similar  transaction,   an
appropriate  adjustment,  determined  by the  Board  of  Directors  in its  sole
discretion, will be made in the number and kind of shares and the exercise price
per share of options which are outstanding.

Administration

     The Compensation  Committee of the Board of Directors administers the Stock
Option  Plan.  The  current  members  of the  Compensation  Committee  are H. S.
Winokur, Jr., R. E. Dougherty, and P. G. Kaminski. The address of each member is
11710 Plaza America Drive, Reston, Virginia 20190. The Compensation Committee is
appointed  annually by the Board of Directors,  which may also fill vacancies or
replace members of the Compensation Committee.

Subject to the express  provisions  of the Stock Option Plan,  the  Compensation
Committee has the authority to:

     o  interpret the Stock Option Plan,

     o  prescribe, amend, and rescind rules and regulations relating to the
        Stock Option Plan,

     o  determine  the  individuals  to whom  and the  time or  times  at which
        options  may be granted  and the number of shares to be subject to each
        option granted under the Stock Option Plan,

     o  determine the terms and conditions of the option agreements under the
        Stock Option Plan, which need not be identical, and

     o  make all other determinations necessary or advisable for the administra-
        tion of the Stock Option Plan.

     The members of the Compensation  Committee receive no compensation from the
Stock Option Plan for services rendered in connection therewith.

Federal Income Tax Consequences

     In our  view,  the  following  discussion  includes  a  description  of all
material federal income tax considerations relating to the Stock Option Plan. We
have not received an opinion of counsel with respect to this discussion.

     All options  granted  under the Stock Option Plan are  non-qualified  stock
options;  that is,  they do not receive the same  treatment  under the  Internal
Revenue Code as do "qualified" stock options.  Generally,  the optionee will not
be taxed at the time of the grant of a non-qualified  stock option.  At the time
of exercise of such option,  the optionee  will  recognize  ordinary  income for
federal  income tax purposes in an amount equal to the excess of the fair market
value, at the time of exercise,  of the common stock purchased over the exercise
price. We will generally be entitled to a company tax deduction at such time and
in the same amount that the optionee realizes ordinary income.

     If common stock acquired upon the exercise of a non-qualified  stock option
is later sold or exchanged,  then the difference  between the sale price and the
fair market value of the shares on

the date  which  governs  the  determination  of  ordinary  income is  generally
taxable,  provided  the  stock is a  capital  asset in the  holder's  hands,  as
long-term or short-term capital gain or loss,  depending upon the holding period
for such common stock at the time of disposition.

     If payment of the exercise price of a non-qualified stock option is made by
surrendering previously owned shares of common stock, the following rules apply:
<PAGE>

     o   No gain or loss  will be  recognized  as a result of the  surrender  of
         shares  in  exchange  for an equal  number  of  shares  subject  to the
         non-qualified stock option;

     o   The number of shares received equal to the shares surrendered will have
         a basis  equal to the  shares  surrendered  and a holding  period  that
         includes the holding period of the shares surrendered; and

     o   Any additional  shares received (1) will be taxed as ordinary income in
         an amount  equal to the fair market  value of the shares at the time of
         exercise, (2) will have a basis equal to the amount included in taxable
         income by the optionee,  and (3) will have a holding period that begins
         on the date of the exercise.

     The tax treatment of capital gains is discussed  above in the discussion of
federal income taxes for the Employee Stock Purchase Plan. See "Employee Benefit
Plans -- Employee Stock Purchase Plan."

     Holders of options granted under the Stock Option Plan should consult their
own tax  advisors for specific  advice with  respect to all federal,  state,  or
local tax effects  before  exercising  any options and before  disposing  of any
shares of common stock acquired upon the exercise of an option.  Moreover, we do
not represent that the foregoing tax consequences apply to any particular option
holder's specific circumstances or will continue to apply in the future.

EXECUTIVE INCENTIVE PLAN

General

     Our  current  Executive  Incentive  Plan  became  effective  in  1993.  The
Incentive Plan provides for the annual award of  discretionary  bonuses based on
the  achievement of specific  financial and individual  performance  goals.  The
Incentive Plan was amended  effective January 1, 1996 to provide for the payment
of 20% of each  award in the form of shares of common  stock,  based on the most
recent formula price.

     300,000  shares were  reserved for possible  issuance  under the  Incentive
Plan,  and 37,614  shares have been issued to date.  The  Incentive  Plan is not
subject to the Employee Retirement Income Security Act and is not intended to be
qualified under Section 401(a) of the Internal Revenue Code.

Eligibility and Participation

     Officers and certain key executive  employees of DynCorp are  designated by
the Compensation  Committee to be eligible to participate in and receive bonuses
under the Incentive Plan.

Awards

     Each year we establish  bonus pools  representing  the  aggregate  targeted
bonuses negotiated in advance with Incentive Plan participants. Awards under the
Incentive  Plan are  generally  made based upon the  achievement  of  previously
established  individual  and financial  performance  criteria.  Awards under the
Incentive Plan are made based on  recommendations of the Chief Executive Officer
to the Compensation Committee.  Awards of bonuses, including potential shares of
common  stock,  may also be subject to  forfeiture,  in whole or in part, in the
event of the  termination  of the  recipient's  employment or  affiliation  with
DynCorp prior to the date for payment of awards.

     Awards of bonuses under the Incentive Plan are generally distributed after
the end of the fiscal year to which the bonus relates.  After calculation of the
bonus amount,  20% of the bonus amount,  net of applicable taxes, is made in the
form of shares of common stock, valued at the formula price.

     Pursuant to our by-laws,  all shares of common stock  distributed under the
Incentive  Plan will be subject to our right of first  refusal in the event that
the  participant  desires to sell such shares other than on the  internal  stock
market. See "Description of Capital Stock -- Restrictions on Common Stock."
<PAGE>

     For  services  rendered  during the fiscal year ended  December 30, 1999, a
total of 23 individuals received an aggregate of 5,158 shares of common stock as
the stock portion of bonuses under the Incentive Plan.

Federal Income Tax Consequences

     In our  view,  the  following  discussion  includes  a  description  of all
material  federal income tax  considerations  relating to the Incentive Plan. We
have not received an opinion of counsel with respect to this discussion.

     Awards under the Incentive Plan of cash bonuses and shares of common stock,
valued at fair  market  value at the time of  receipt,  that are not  subject to
forfeiture  are  taxable  as  ordinary  income to the  recipient  at the time of
receipt.

     Recipients of awards under the Incentive  Plan should consult their own tax
advisors  with  respect  to  all  federal,  state,  and  local  tax  effects  of
participation in the Incentive Plan.  Moreover,  DynCorp does not represent that
the  foregoing  tax  consequences  will  apply to any  particular  participant's
specific circumstances.

Amendment and Termination

     The  Incentive  Plan  may at any  time  be  amended  or  terminated  by the
Compensation Committee.

Administration

     The Compensation Committee of the Board of Directors administers the
Incentive Plan.


                         Description of Capital Stock

General

     The authorized  capital stock of DynCorp  consists of 20,000,000  shares of
common stock, par value $0.10 per share, of which, as of May 1, 2000, 10,413,708
shares are outstanding, and 123,711 shares of Class C Preferred, par value $0.10
per  share,  of which  none  are  outstanding.  As of May 1,  2000,  there  were
approximately 730 holders of record of common stock.

     The following is a summary of the material provisions of our certificate of
incorporation  and  by-laws  regarding  our  capital  stock.  The summary is not
complete and is qualified  in its  entirety by reference to the  certificate  of
incorporation and by-laws,  copies of which are incorporated by reference to the
registration statement of which this prospectus is a part.

Common Stock

     The  holders  of common  stock are  entitled  to one vote per share held of
record in elections for directors and on all other matters required or permitted
to be  approved  by a vote of our  stockholders.  Each share of common  stock is
equal in respect  of rights  and  liquidation  and  rights to  dividends  and to
distributions.  Stockholders will not have any preferred or preemptive rights to
subscribe for,  purchase,  or receive  additional shares of any class of capital
stock of DynCorp,  or any options or warrants for such shares,  or any rights to
subscribe for or purchase such shares,  or any  securities  convertible  into or
exchangeable for such shares,  which may be issued, sold, or offered for sale by
DynCorp.
<PAGE>

Restrictions on Common Stock

     The Board of Directors of DynCorp  amended our by-laws on May 10, 1995,  to
provide  that no share of common  stock  issued on or after May 11,  1995 may be
sold or transferred by the stockholder to any third party, other than by descent
or  distribution,  bona fide gift,  or bona fide sale. A bona fide sale may only
occur after the  stockholder  has first  offered in writing to sell the share to
DynCorp at the same price and under substantially the same terms as apply to the
intended  sale,  and  DynCorp  has failed or  declined in writing to accept such
terms within 14 days of receipt of such written  offer or has refused to proceed
to a closing on the transaction  within a reasonable time. The sale to the third
party following such failure,  declination,  or refusal must be made on the same
terms which were not previously accepted by DynCorp and within 60 days following
such event, or DynCorp must again be offered such refusal rights prior to a sale
of such share.

     Our right of first refusal right does not apply to:

     o  any transactions made at the current formula price through the internal
        stock market,

     o  any transactions made at any time while the common stock is listed for
        trading on a national securities exchange or on the over-the-counter
        market,

     o  sales to the ESOP, or

     o  shares  which have been  reissued to the holder in exchange  for shares
        issued  prior to May 11,  1995 to the  extent  such  previously  issued
        shares were not subject to any right of first refusal by DynCorp or its
        stockholders.

     Shares of common  stock  purchased  on the  internal  stock  market will be
subject to  contractual  transfer  restrictions  having the same effect as those
contained in the by-laws.  Prior to trading on the internal  stock market,  each
buyer will be required  to adhere to the  internal  stock  market  rules,  which
impose such transfer  restrictions on all shares purchased on the internal stock
market. Shares of common stock issued prior to May 11, 1995 and not subsequently
purchased on the internal stock market are not subject to such restrictions. See
"Risk Factors -- Right of First Refusal."




                            Validity of Common Stock


     The validity of the common stock offered by this prospectus has been passed
upon for DynCorp by H.  Montgomery  Hougen,  Vice  President  and  Secretary and
Deputy General Counsel of DynCorp.  As of May 1, 2000, Mr. Hougen owned directly
and indirectly 11,467 shares of common stock and options to purchase 9,500
shares of common stock.  Mr. Hougen is the beneficial owner of an additional
3,934 shares through our benefit plans.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14.  Other Expenses of Issuance and Distribution.

     Not applicable.

Item 15.  Indemnification of Directors and Officers.

     Section 102 of the General Corporation Law of the State of Delaware ("GCL")
allows a corporation  to eliminate  the personal  liability of a director to the
corporation  or its  stockholders  for monetary  damages for breach of fiduciary
duty as a director,  except in cases  where the  director  breached  his duty of
loyalty,  failed to act in good faith,  engaged in  intentional  misconduct or a
knowing  violation  of law,  authorized  the  unlawful  payment of a dividend or
approved an unlawful  stock  redemption  or  repurchase  or obtained an improper
personal  benefit.   The  Registrant's   Amended  and  Restated  Certificate  of
Incorporation,  a copy of  which is filed  as an  exhibit  to this  registration
statement,  contains a provision which eliminates  directors' personal liability
as set forth above.

     The Amended and Restated Certificate of Incorporation of the Registrant and
the  Bylaws of the  Registrant  provide  in  effect  that the  Registrant  shall
indemnify  its  directors,  officers and  employees  to the extent  permitted by
Section  145 of  the  GCL.  Section  145 of the  GCL  provides  that a  Delaware
corporation  has the power to indemnify  its  officers and  directors in certain
circumstances.

     Subsection  (a) of  Section  145 of  the  GCL  empowers  a  corporation  to
indemnify any director or officer, or former director or officer,  who was or is
a party  or is  threatened  to be made a party  to any  threatened,  pending  or
completed action, suit or proceeding,  whether civil, criminal,  administrative,
or investigative  (other than an action by or in the right of the  corporation),
against expenses (including attorneys' fees), judgments,  fines and amounts paid
in settlement  actually and reasonably  incurred in connection with such action,
suit or proceeding provided that such director or officer acted in good faith in
a manner  reasonably  believed to be in or not opposed to the best  interests of
the  corporation,  and,  with  respect  to any  criminal  action or  proceeding,
provided  that such  director  or  officer  had no cause to  believe  his or her
conduct was unlawful.

     Subsection  (b) of Section 145  empowers a  corporation  to  indemnify  any
director or officer, or former director or officer,  who was or is a party or is
threatened to be made a party to any threatened,  pending or completed action or
suit by or in the right of the corporation to procure a judgment in its favor by
reason of the fact that such  person  acted in any of the  capacities  set forth
above,  against expenses actually and reasonably incurred in connection with the
defense or  settlement  of such action or suit  provided  that such  director or
officer acted in good faith and in a manner reasonably  believed to be in or not
opposed to the best interests of the corporation, except that no indemnification
may be made in respect of any claim,  issue or matter for which such director or
officer  shall have been  adjudged to be liable for  negligence or misconduct in
the  performance  of his or her duty to the  corporation  unless and only to the
extent  that the Court of Chancery or the court in which such action was brought
shall  determine  that despite the  adjudication  of liability  such director or
officer is fairly and  reasonably  entitled to indemnity for such expenses which
the court shall deem proper.

     Section 145 further  provides that to the extent a director or officer of a
corporation has been successful in the defense of any action, suit or proceeding
referred to in subsections (a) and (b) or in the defense of any claim,  issue or
matter  therein,  he or she shall be  indemnified  against  expenses  (including
attorneys'  fees) actually and  reasonably  incurred by him or her in connection
therewith;  that indemnification provided for by Section 145 shall not be deemed
exclusive  of any other rights to which the  indemnified  party may be entitled;
and empowers the  corporation to purchase and maintain  insurance on behalf of a
director or officer of the corporation  against any liability  asserted  against
him or her or incurred by him or her in any such  capacity or arising out of his
or her  status as such  whether or not the  corporation  would have the power to
indemnify him or her against such liabilities under Section 145.

Item 17. Undertakings

     The undersigned Registrant hereby undertakes:

     1. To file,  during any period in which  offers or sales are being made, a
post-effective amendment to the registration statement:

         (a)  To include any prospectus required by Section 10(a)(3) of the
         Securities Act.

         (b) To reflect in the  prospectus any facts or events arising after the
         effective  date  of the  registration  statement  (or the  most  recent
         post-effective  amendment  thereof)  which,   individually  or  in  the
         aggregate,  represent a fundamental change in the information set forth
         in the  registration  statement.  Notwithstanding  the  foregoing,  any
         increase or decrease in the volume of securities  offered (if the total
         dollar  value of  securities  offered  would not exceed  that which was
         registered) and any deviation from the low or high end of the estimated
         maximum offering range may be reflected in the form of prospectus filed
         with the Commission  pursuant to Rule 424(b) if, in the aggregate,  the
         changes in volume and price  represent no more than a 20 percent change
         in the maximum  aggregate  offering price set forth in the "Calculation
         of Registration Fee" table in the effective registration statement; and

         (c) To include any  material  information  with  respect to the plan of
         distribution not previously disclosed in the registration  statement or
         any material change to such information in the registration statement;

Provided, however, that paragraphs 1(a) and 1(b) do not apply if the information
required to be included in a  post-effective  amendment by those  paragraphs  is
contained in periodic reports filed by the Registrant  pursuant to section 13 or
section  15(d) of the  Exchange  Act that are  incorporated  by reference in the
registration statement.

     2. That, for the purpose of determining  any liability under the Securities
Act, each such post-effective amendment shall be deemed to be a new registration
statement relating to the securities  offered therein,  and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.

     3. To remove from  registration by means of a post-effective  amendment any
of the securities being registered which remain unsold at the termination of the
offering.

     Insofar as  indemnification  for  liabilities  arising under the Act may be
permitted to  directors,  officers  and  controlling  persons of the  Registrant
pursuant to the foregoing  provisions,  or otherwise,  the  Registrant  has been
informed that in the opinion of the Commission such  indemnification  is against
public  policy  as  expressed  in  the   Securities   Act  and  is,   therefore,
unenforceable.  In the  event  that a claim  for  indemnification  against  such
liabilities  (other than the payment by the  Registrant of expenses  incurred or
paid by a  director,  officer or  controlling  person of the  Registrant  in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director, officer or controlling person in conjunction with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
