                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors of
Raytheon Company:

We have audited the accompanying balance sheets of Xyplex, Inc. as of December
31, 1995 and 1994, and the related statements of income, stockholder's equity,
and cash flows for the years then ended. These financial statements are the
responsibility of management. Our responsibility is to express an opinion on
these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 1, interest expense associated with Raytheon Company's
general corporate debt has not been allocated to Xyplex, Inc.'s financial
statements. Also as discussed in Note 1, Xyplex, Inc. has earned interest income
primarily on its intercompany receivable from Raytheon based on an agreed-upon
rate. As discussed in Note 2, certain costs and expenses presented in the
financial statements represent allocations of the costs of services provided to
Xyplex, Inc. by Raytheon Company. As a result of these factors, the financial
statements presented may not be indicative of the financial position or results
of operations that would have been achieved had Xyplex, Inc. operated as a
nonaffiliated entity.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Xyplex, Inc. as of December 31,
1995 and 1994, and the results of its operations and its cash flows for the
years then ended in conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS


1.   Summary of Significant Accounting Policies:
     ------------------------------------------

     Basis of Presentation

     Xyplex, Inc. (the "Company" or "Xyplex") designs, manufactures, markets and
     supports data networks. On October 7, 1994, Xyplex was acquired by Raytheon
     Company ("Raytheon") for total consideration of $186,000,000. Pursuant to
     the purchase method of accounting, the assets and liabilities acquired by
     Raytheon were revalued to their fair value. The excess of the purchase
     price over the fair value of the net assets acquired was approximately
     $125,000,000 and accordingly, goodwill and the parent company investment
     were increased by $125,000,000. Effective on the close of business on April
     9, 1996, Xyplex was acquired by Whittaker Corporation.

     The accompanying historical financial statements present the Company's
     results of operations and its financial condition as a stand alone entity
     through October 7, 1994 and as a wholly-owned subsidiary of Raytheon
     thereafter. Interest expense associated with Raytheon's general corporate
     debt has not been allocated to the Company's financial statements. Certain
     costs and expenses presented in the financial statements represent
     intercompany allocations and management's estimates of the costs of
     services provided to the Company by Raytheon. (See Note 2 for further
     discussion of allocations.) Additionally, as discussed in further detail
     below, Xyplex earned interest income primarily on its intercompany
     receivable from Raytheon based on an agreed-upon rate. As a result of these
     factors, the financial statements presented may not be indicative of the
     results that would have been achieved had the Company operated as a non-
     affiliated entity.

     The Company has had transactions in the normal course of business with
     Raytheon and its subsidiaries. Revenues from these transactions, totaling
     $1,172,000 in 1995 and $128,000 in 1994, are in accordance with Xyplex's
     normal terms and conditions. The remaining receivables from these
     transactions with Raytheon are included in trade accounts receivable and
     totaled $458,000 and $28,000 as of December 31, 1995 and 1994,
     respectively.

     Additionally, Xyplex transferred a substantial amount of its cash and
     investments to Raytheon upon the acquisition date and has subsequently
     participated in the Raytheon cash management program. All of this cash
     management activity is recorded in the receivable from parent company
     account. Intercompany activity also includes allocations of corporate
     expenses, state and federal income tax payments and credits, and interest
     earned on the intercompany receivable balance itself. Interest is earned on
     the intercompany receivable balance at a rate of 6.25% in 1995 and 5% in
     1994 and totaled approximately $2,238,000 in 1995 and $212,000 in 1994.

                                   Continued

                   NOTES TO FINANCIAL STATEMENTS, CONTINUED

     Parent Company Investment

     The parent company investment account represents the net assets of the
     company. As described above, this account was credited with the excess of
     the purchase price over the fair value of Xyplex's net assets at the time
     of Raytheon's purchase.

     Principles of Consolidation

     The accompanying financial statements include the accounts of the Company
     and its wholly owned subsidiaries, Xyplex Foreign Sales Corporation, Inc.,
     a foreign sales corporation formed in April 1990 and Xyplex Security Corp.,
     formed in May 1991. Significant intercompany accounts and transactions have
     been eliminated in consolidation. The assets of Xyplex Security Corp. were
     liquidated during 1994 after the Company was purchased by Raytheon.
     Effective in 1995, the Company's foreign sales were reported under
     Raytheon's foreign sales corporation (RITL).

     Use of Accounting Estimates

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amount of assets and liabilities and
     disclosure of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues and expenses
     during the reporting period. Actual results could differ from those
     estimates.

     Cash Equivalents and Short-Term Investments

     Cash equivalents include all highly liquid investments with original
     maturities of ninety days or less at the time of acquisition. All other
     investments are considered to be short-term investments and are recorded at
     cost which approximates fair value. Under the Company's cash management
     system with Raytheon, checks issued but not presented to banks frequently
     result in overdraft balances for accounting purposes. The Company has
     determined the net overdraft balance by bank and has correspondingly
     reclassified these amounts to Accounts Payable.

     Revenue Recognition

     The Company recognizes product revenue upon shipment of goods and software.
     Maintenance and support fees greater than $10,000 are recognized ratably
     over the life of the contract. A provision is made at the time of shipment
     for estimated warranty costs to be incurred.

     Inventory

     Inventories are stated at the lower of cost (first-in, first-out method) or
     market.

     Property and Equipment

     Property and equipment are recorded at cost. Expenditures for maintenance
     and repairs are charged to expense while the costs of significant
     improvements are capitalized. Depreciation is computed using the straight-
     line and accelerated methods in amounts that allocate the cost of these
     assets over their estimated useful lives as follows:

     Upon retirement or sale, the cost of assets disposed and the related
     accumulated depreciation are eliminated and the related gains or losses are
     reflected in income.

     Intangibles

     Goodwill, which represents the amount Raytheon incurred in excess of the
     fair value of the net assets of Xyplex on the date of purchase, is
     amortized on a straight-line basis over a period of 15 years. For the years
     ended December 31, 1995 and 1994, the Company incurred amortization expense
     related to this asset of $8,358,000 and $1,393,000. Accumulated
     amortization related to goodwill totaled $9,751,000 and $1,393,000 as of
     December 31, 1995 and 1994.

     Other intangibles assets, consisting primarily of licenses, are included in
     other assets. These assets are amortized over a one to three year period
     based on net realizable value. For the years ended December 31, 1995 and
     1994, the Company incurred amortization expense of $444,000 and $245,000.
     Accumulated amortization related to these other assets totaled $624,000 and
     $180,000 as of December 31, 1995 and 1994.

                   NOTES TO FINANCIAL STATEMENTS, CONTINUED

     The Company periodically reviews the carrying value of its intangible
     assets as well as the amortization periods to determine whether current
     events and circumstances warrant adjustment to the carrying values or
     estimated useful lives. At each balance sheet date, management evaluates
     the carrying value of intangible assets to determine whether there has been
     any permanent impairment. As of December 31, 1995, the Company recognized
     goodwill impairment of $30,000,000. This amount represents the approximate
     difference between the fair value and the carrying value of the Company's
     net assets based on the anticipated sale of the Company.

     Research and Development and Software Development Costs

     Research and development costs are charged to expense as incurred. In
     accordance with Statement of Financial Accounting Standards (SFAS) No. 86,
     capitalization of internally developed computer software costs begins upon
     the establishment of technological feasibility. The Company believes that
     once a working model has been established, the additional development costs
     to bring the product to a commercially acceptable level are not
     significant. There were no software development costs capitalized as of
     December 31, 1995 and 1994.

     Income Taxes

     The Company records income taxes based on an asset and liability approach
     which results in the recognition of deferred tax assets and liabilities for
     the expected future tax consequences of temporary differences between the
     book and tax bases of assets and liabilities. For purposes of these
     financial statements, income taxes have been calculated as if Xyplex had
     prepared a tax return on a stand alone basis.

     In accordance with Raytheon's policy, all state and local taxes have been
     included in general and administrative expenses.

2.   Allocated Costs:
     ---------------

     The historical statements of operations include charges from Raytheon
     representing the Company's share of the cost of support services provided.
     These charges are allocations of corporate expenses associated with legal,
     marketing, management, financial and facilities management services. The
     basis of the allocation is dependent on the functions and includes net
     sales, square feet occupied, and percentage share of all other corporate
     assessments. For these services, the Company was charged $425,000 and
     $24,000 in 1995 and 1994, respectively.

     Management believes the methods used to allocate the costs are reasonable
     based on the company's use of such facilities and services.

     Equipment under capital leases had accumulated amortization of $2,942,000
     and $2,078,000 as of December 31, 1995 and 1994. Acquisitions for equipment
     under capital lease obligations totaled $477,000 in 1994. There were no
     such acquisitions in 1995.

5.   Long-Term Debt:
     --------------

     At December 31, 1993, the Company had approximately $253,000 outstanding
     under a term note payable. Until the acquisition by Raytheon, the Company
     made the required monthly principal payments of approximately $23,000 plus
     interest. In October 1994, the Company paid this note off in full.

6.   Stock Plans:
     -----------

     During 1994, the Company had two stock options plans in effect: the 1991
     Restated Stock Option Plan (the "1991 Plan") and the 1989 Consultant's
     Stock Option Plan (the "1989 Plan"). Under the 1991 Plan, incentive stock
     options were granted at an exercise price of not less than the fair market
     value of common stock as determined in accordance with the 1991 Plan and
     nonqualified options were granted at an exercise price of not less than 50%
     of the fair market value of the common stock at the date of grant. Under
     the 1989 Plan, stock options were granted to eligible consultants, as
     defined, at a price of not less than the fair value of the common stock at
     the date of grant. At the time the Company was acquired by Raytheon, the
     outstanding options of both of these plans were exchanged for options to
     purchase Raytheon stock.

     Prior to the acquisition by Raytheon, the Company also had the 1991
     Employee Stock Purchase Plan (the "ESPP") in effect. Under the terms of the
     ESPP, the company was authorized to grant options to purchase an aggregate
     of 140,000 shares of common stock in a series of six-month periods. The
     purchase price was 85% of the lower of the fair value per share of common
     stock, as defined in the ESPP. At the time the Company was acquired by
     Raytheon, these shares were converted to Raytheon stock.

7.   Income Taxes:

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                     For the Year Ended December 31, 1993


(1)  OPERATIONS

Xyplex, Inc. (The "Company") a Massachusetts corporation, designs, manufactures,
markets and supports data networks based on the Network 9000 Routing Hub. The
Network 9000 features a robust architecture that will allow seamless integration
of emerging technologies and supports a comprehensive suite of media connection
types, routing, bridging, switching and remote access servers.

(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accompanying consolidated financial statements reflect the application of
certain accounting policies described below and elsewhere in the notes to
consolidated financial statements.

(a)  Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the
Company and its wholly owned subsidiaries, Xyplex Foreign Sales Corporation,
Inc., a foreign sales corporation formed in April 1990, and Xyplex Security
Corp., formed in May 1991. Significant intercompany accounts and transactions
have been eliminated in consolidation.

(b)  Cash and Cash Equivalents and Short-Term Investments

For purposes of the statements of cash flows, the Company considers all highly
liquid investments with original maturities of ninety days or less at the time
of acquisition to be cash equivalents. All other investments are considered to
be short-term investments and are recorded at cost which approximates market
value. The Company is required to adopt Statement of Financial Accounting
Standards (SFAS) No. 115, "Accounting for Certain Investments in Debt and Equity
Securities," in 1994. The Company does not expect this to have a material effect
on its classification or results of operations of its investments. At December
31, 1993, cash and cash equivalents and short-term investments include the
following (rounded to the nearest thousand):

(2)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

(g)  Research and Development and Software Development Costs

Research and development costs, other than software development costs, have been
charged to operations as incurred. Statement of Financial Accounting Standards
No. 86, "Accounting for the Costs of Computer Software to be Sold, Leased or
Otherwise Marketed" ("SFAS 86"), requires the capitalization of certain computer
software development costs incurred after technological feasibility is
established. The Company believes that once technological feasibility of a
software product has been established, the additional development costs incurred
to bring the product to a commercially acceptable level are not significant.
There were no capitalized software development costs at December 31, 1993.

(h)  Net Income per Common and Common Equivalent Share

Net income per common and common equivalent share has been computed using the
weighted average number of shares of common stock and common stock equivalents
outstanding during each period. Common stock equivalents outstanding are stock
options that have been included in the computation using the treasury stock
method only when their effects would be dilutive.

Fully-diluted net income per common and common equivalent share has not been
separately presented, as the amounts are not materially different from primary
income per share.

(3)  LONG-TERM DEBT

(a)  Fixed Asset Line of Credit

At December 31, 1993, the Company had borrowings of approximately $253,000,
which converted to a term note payable, on a $1,500,000 fixed asset line of
credit with a bank. The line expired in June 1993, and was renewed until June
1994. Any outstanding borrowings at the end of the drawdown period will be
repaid commencing June 30, 1994 in 24 equal monthly installments plus interest.
The Company was required to pay a facility fee of 0.25% of the total line.
Borrowings under this line accrue interest at the bank's prime rate (6.0% at
December 31, 1993) and are secured by the equipment purchased.

(3)  LONG-TERM DEBT (Continued)

(b)  Working Capital Line of Credit

At December 31, 1993, the Company had an unsecured demand working capital line
of credit with a bank, under which it can borrow the lesser of $3,500,000 or 80%
of qualified accounts receivable. This line expires in June 1994. The Company
was required to pay a facility fee of 0.25% of the total line. Borrowings under
this line accrue interest at the bank's prime rate (6.0% at December 31, 1993).
No borrowings were outstanding on this line of credit at December 31, 1993.

(c)  Lease Line of Credit

During 1993, the Company had a $1,250,000 lease line of credit with a bank
against which the Company executed one drawdown in May 1993 for approximately
$499,000 at an interest rate approximately 250 basis points above like-term
treasury bills. Borrowings against this lease line of credit at December 31,
1993 were $684,000, and are payable in 36 equal monthly installments. This lease
line expired in June 1993, and was renewed through June 1994 with a different
bank for approximately $1,500,000 at the bank's internal cost of funds plus 150
basis points. In 1993, the Company executed two drawdowns against this lease
line, one in September 1993 for approximately $184,000 and the second in
December 1993 for approximately $679,000. Borrowings against this lease line of
credit at December 31, 1993 were $863,000, and are payable in 36 equal monthly
installments.

(d)  Term Notes Payable

At December 31, 1993, the Company had approximately $253,000 outstanding under
its term notes payable to a bank. The Company continues to make payments on its
term notes in 30 equal monthly principal payments of approximately $23,000, plus
interest. Principal payments will be $203,000 and $50,000, in 1994 and 1995,
respectively. Interest accrues at the bank's prime rate (6.0% at December 31,
1993). Borrowings under these notes are secured by specific fixed assets of the
Company.

Certain of the above debt agreements require the Company to maintain certain
levels of tangible net worth, quick ratio, and debt to equity ratio, among other
requirements.

(4)  COMMON STOCK

In May 1991, the Company completed its initial public offering of 1,800,000
shares of common stock at a price of $14 per share. The Company received
$22,804,000, net of approximately $630,000 in offering expenses.

(b)  Reverse Stock Split

The stockholders approved a one-for-three reverse stock split of common stock on
March 12, 1991. The accompanying consolidated financial statements have been
retroactively restated to reflect this stock split.

(5)  PREFERRED STOCK

Upon the closing of the Company's initial public offering in May 1991, all of
the outstanding shares of the Class C, D and E preferred stock were
automatically converted into approximately 3,157,000 shares of common stock. The
Company had 5,000,000 shares of undesignated preferred stock, par value $0.01
per share, authorized immediately after the closing of the initial public
offering. The Board of Directors is authorized, subject to any limitation
prescribed by law, without further stockholder approval, to issue up to
5,000,000 shares of preferred stock in one or more series. The Board of
Directors shall determine the number of shares, designations, preferences,
voting powers, qualifications, and other rights and privileges of each series of
preferred stock.

(6)  STOCK PLANS

On March 12, 1991, the stockholders approved the 1991 Restated Stock Option Plan
(the "1991 Plan") which restated the 1988 Incentive Stock Option Plan. Under the
1991 Plan, incentive stock options generally may be granted at an exercise price
of not less than the fair market value of common stock as determined in
accordance with the 1991 Plan. Under the 1991 Plan, non-qualified options may be
granted at an exercise price of not less than 50% of the fair market value of
the common stock at the date of grant. On May 22, 1993, four non-employee
directors were each granted 1,000 non-qualified options, at a fair market value
of $26.00 per share under the 1991 Plan.

On August 15, 1989, the stockholders approved the 1989 Consultants' Stock Option
Plan (the "1989 Plan"). Under the 1989 Plan, stock options may be granted to
eligible consultants, as defined, at a price of not less than the fair market
value of the common stock at the date of grant.

At December 31, 1993, the Company had 919,135 and 333 shares of its common stock
reserved for issuance upon the exercise of options granted under the 1991
Restated Stock Option Plan and the 1989 Consultants' Stock Option Plan,
respectively.

All incentive stock options granted under the 1991 Plan and all options granted
under the 1989 Plan expire not more than 10 years from the date of grant, and
the Compensation Committee, under the authority delegated by the Board,
prescribes the date or dates on which the options become exercisable.

On March 12, 1991, the stockholders approved the 1991 Employee Stock Purchase
Plan (the "ESPP"). Under the terms of the ESPP, the Company is authorized to
grant options to purchase an aggregate of 60,000 shares of common stock in a
series of six-month periods. On May 7, 1993, the stockholders increased the
number of shares subject to the ESPP by 80,000 shares to a total of 140,000 
shares. The purchase price is 85% of the lower of the fair market value per
share of common stock, as defined in the ESPP. During 1992, the stockholders
amended the ESPP to eliminate the requirement that employees must first be
employed by the Company for at least 90 days before participating in the Plan.
As of December 31, 1993, the Company had 73,655 shares of common stock available
for grant under the ESPP.

             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS


Note 1.   Corporate Relationship

Xyplex, Inc. (the "Company") was acquired by Raytheon Company ("Raytheon") on
October 7, 1994. Effective on the close of business on April 9, 1996, Xyplex was
acquired by Whittaker Corporation.

The condensed financial statements present the Company's results of operations
and its financial condition as a wholly-owned subsidiary of Raytheon. Interest
expense associated with Raytheon's general corporate debt has not been allocated
to the Company's financial statements, which also include certain intercompany
allocations which represent management's estimates of the costs of services
provided to the Company by Raytheon. In addition, the Company earned interest
income primarily on its intercompany receivable from Raytheon based on an 
agreed-upon rate. As a result of these factors, the financial statements
presented may not be indicative of the results that would have been achieved had
the Company operated as a non-affiliated entity.

Note 2.   Basis of Presentation

While the quarterly financial information contained in this filing is unaudited,
the financial statements presented reflect all adjustments (consisting only of
normal recurring accruals) which the Company considers necessary for a fair
presentation of the results of operations for the interim periods covered and of
the financial condition of the Company at the date of the interim balance sheet.
The information included in this report should be read in conjunction with the
Company's audited financial statements and notes thereto.

Item 7(b).  Pro Forma Financial Information

                             WHITTAKER CORPORATION
             PRO FORMA CONDENSED COMBINING STATEMENTS OF OPERATIONS

On April 10, 1996, Whittaker Corporation (the "Company") acquired all of the
stock of Xyplex, Inc. ("Xyplex"), a wholly-owned subsidiary of Raytheon Company
("Raytheon"). The purchase price was $67.5 million in cash, subject to certain
adjustments, and $50.0 million in the form of 1,974,333 newly issued shares of
the Company's common stock. Other direct costs associated with the acquisition
were approximately $1.3 million. On April 24, 1995, the Company acquired all of
the stock of Hughes LAN Systems, Inc. ("HLS"), a subsidiary of Hughes
Electronics Corporation. The subsidiary was renamed Whittaker Communications
Inc. ("WCI"), and was acquired for a purchase price of $16.0 million in cash,
subject to certain adjustments, and a $15.0 million convertible subordinated
note. The HLS acquisition agreement also provides for contingent deferred
payments, not to exceed $25.0 million, based on future sales of certain WCI
products during the period November 1, 1995 through October 31, 1999.

The following unaudited pro forma condensed combining statements of operations
of the Company and its subsidiaries are based upon the combination of the
historical financial statements of the Company, and the historical financial
statements of Xyplex and WCI prior to their acquisition by the Company. The
unaudited pro forma condensed combining statement of operations for the year
ended October 31, 1995 has been prepared to illustrate the effect of the two
business combinations, each of which has been accounted for as a purchase, as
though each business combination occurred on November 1, 1994. The unaudited pro
forma condensed combining statement of operations for the six months ended April
30, 1996 has been prepared to illustrate the effect of the Xyplex purchase as
though it had occurred on November 1, 1995.

The pro forma adjustments and the assumptions on which they are based are
described in the accompanying Notes to Unaudited Pro Forma Condensed Combining
Statement of Operations. Because the acquisitions of both Xyplex and WCI were
completed prior to April 30, 1996, the balance sheets of both entities are
included in the consolidated balance sheet of the Company as of April 30, 1996
which is included in its Form 10-Q for the period ended April 30, 1996.

The Company has not completed all appraisals and evaluations necessary to
finalize Xyplex's purchase price allocations and accordingly, actual adjustments
that reflect appraisals and other evaluations of the purchased assets and
assumed liabilities may differ from the pro forma adjustments presented herein. 
Such evaluations may include restructuring or other integration actions 
involving Xyplex and WCI which may result in adjustments to the purchase price 
allocation and charges to income.  The unaudited pro forma condensed combining
statements of operations are presented for illustrative purposes only and are
not necessarily indicative of the consolidated results of operations of the
Company that would have been reported had the business combinations occurred on
the dates indicated, nor do they represent a forecast of the consolidated
results of operations of the Company for any
<PAGE>
 
future period. Furthermore, no effect has been given in the unaudited pro forma
condensed combining statements of operations for operating and synergistic
benefits that may be realized through the combination of the entities. The
unaudited pro forma condensed combining statements of operations, including the
Notes thereto, should be read in conjunction with the historical consolidated
financial statements of the Company and Xyplex which are incorporated herein by
reference, and included herein, respectively.

                         NOTES TO UNAUDITED PRO FORMA
                 CONDENSED COMBINING STATEMENT OF OPERATIONS
                      For the Year Ended October 31, 1995


Note 1.   General

The Whittaker Corporation unaudited pro forma condensed combining statement of
operations and related notes give effect to the business combinations of Xyplex
and WCI as purchases. The unaudited pro forma condensed combining statement of
operations of the Company and its subsidiaries, Xyplex, and WCI for the year
ended October 31, 1995 assumes that each business combination occurred on
November 1, 1994. Xyplex and WCI historical financial statements are for fiscal
years ended December 31 and accordingly, the historical information for the
calendar quarters of both entities has been combined with the fiscal quarters of
the Company for the purpose of the pro forma presentation.

All interim financial data used to develop the Whittaker Corporation unaudited
pro forma condensed combining statement of operations is unaudited, but in the
opinion of the Company's management, reflects all adjustments necessary
(consisting only of normal recurring entries) for a fair presentation thereof.
However, it should be understood that accounting measurements at interim dates
may be less precise than at year end.

The preliminary allocation of the Xyplex purchase price among the identifiable
tangible and intangible assets, as reflected in the accompanying pro forma 
condensed combining statement of operations, was based on an analysis of the
fair value of those assets. The Company continues to analyze the assets acquired
and liabilities assumed and further adjustments to the purchase price and
changes in the allocation of the purchase price may occur. Acquired in-process
research and development was analyzed through interviews and analysis of data
concerning each Xyplex developmental project. Expected future cash flows of each
such project were discounted to present value taking into account risks
associated with the inherent difficulties and uncertainties in completing the
project, and thereby achieving technological feasibility, and risks related to
the viability of and potential changes in future markets. This analysis resulted
in approximately $11.7 million of acquired in-process research and development,
which, under generally accepted accounting principles, was expensed immediately
upon the completion of the acquisition in the period ended April 30, 1996 and
reflected in the historical statement of income of Whittaker for that period.

                         NOTES TO UNAUDITED PRO FORMA
                  CONDENSED COMBINING STATEMENT OF OPERATIONS
                      For the Year Ended October 31, 1995
                                  (Continued)


Note 1.   General (Continued)

Xyplex's developed technology was analyzed using the same methodology and
resulted in an estimated value of $15.0 million, which is being amortized over
five years. Xyplex's customer base was analyzed by determining the estimated
cost to reconstruct the customer base, and resulted in an estimated value of
$20.0 million, which is being amortized over fifteen years. Xyplex's workforce
was analyzed by determining, on a replacement cost basis, the cost to find and
interview candidates and train new employees in their new positions, and
resulted in an estimated value of $2.2 million, which is being amortized over
five years. Goodwill which is related to the ongoing value of the acquired
communications networking business is being amortized over 20 years.

The Company expects to incur additional non-recurring charges during the
remainder of its 1996 fiscal year related to the elimination of duplicate
facilities, relocation and severance costs, and other integration costs. These
amounts have not yet been finalized and are not reflected in the accompanying
pro forma condensed combining statement of operations.

Note 2.   Earnings (Loss) Per Share

The pro forma combined primary earnings (loss) per share have been computed
based on the weighted average number of common shares outstanding during the
period, after increasing the net loss for the dividend requirements on the
Company's outstanding $5.00 Cumulative Preferred Stock. Common stock equivalents
are not dilutive for the pro forma period presented. The exercise of the
conversion option on the 7% convertible subordinated note issued in the HLS
acquisition is not considered dilutive for purposes of calculating fully diluted
earnings (loss) per share.

Note 3.   Pro Forma Adjustments

(a)  Reflects the additional depreciation of property, plant and equipment based
     upon the allocation of purchase price to equipment depreciated using
     methods and terms consistent with those utilized by the Company.

(b)  Reflects the elimination of WCI historical amortization expense totaling
     $1,336,000 and the additional amortization expense of $869,000 based upon
     the allocation of purchase price to intangible assets.

(c)  Reflects the elimination of acquired in-process research and development
     which is directly a result of the acquisition.

                         NOTES TO UNAUDITED PRO FORMA
                 CONDENSED COMBINING STATEMENT OF OPERATIONS
                    For the Six Months Ended April 30, 1996


Note 1.   General

The Whittaker Corporation unaudited pro forma condensed combining statements of
operations and related notes gives effect to the business combination of Xyplex
as a purchase. The unaudited pro forma condensed combining statement of
operations of the Company and its subsidiaries and Xyplex for the six months
ended April 30, 1996, assumes that the Xyplex business combination occurred on
November 1, 1995. The Xyplex historical financial statements are for fiscal
years ended December 31 and accordingly, the historical information for the
calendar quarters has been combined with the fiscal quarters of the Company for
the purpose of the pro forma presentation.

All interim financial data used to develop the Whittaker Corporation unaudited
pro forma condensed combining statement of operations is unaudited, but in the
opinion of the Company's management, reflects all adjustments necessary
(consisting only of normal recurring entries) for a fair presentation thereof.
However, it should be understood that accounting measurements at interim dates
may be less precise than at year end.

The preliminary allocation of the Xyplex purchase price among the identifiable
tangible and intangible assets, as reflected in the accompanying pro forma
condensed combining statement of operations, was based on an analysis of the
fair value of those assets. The Company continues to analyze the assets acquired
and liabilities assumed and further adjustments to the purchase price and
changes in the allocation of the purchase price may occur. Acquired in-process
research and development was analyzed through interviews and analysis of data
concerning each Xyplex developmental project. Expected future cash flows of each
such project were discounted to present value taking into account risks
associated with the inherent difficulties and uncertainties in completing the
project, and thereby achieving technological feasibility, and risks related to
the viability of and potential changes in future markets. This analysis resulted
in approximately $11.7 million of acquired in-process research and development,
which, under generally accepted accounting principles, was expensed immediately
upon the completion of the acquisition in the period ended April 30, 1996 and
reflected in the historical statement of income of Whittaker for that period.
This amount was eliminated in the pro forma condensed combining statement of
operations as it represents a material non-recurring charge.

                         NOTES TO UNAUDITED PRO FORMA
                  CONDENSED COMBINING STATEMENT OF OPERATIONS
                       For the Year Ended April 30, 1996
                                  (Continued)


Note 1.   General (Continued)

Xyplex's developed technology was analyzed using the same methodology and
resulted in an estimated value of $15.0 million, which is being amortized over
five years. Xyplex's customer base was analyzed by determining the estimated
cost to reconstruct the customer base, and resulted in an estimated value of
$20.0 million, which is being amortized over fifteen years. Xyplex's workforce
was analyzed by determining, on a replacement cost basis, the cost to find and
interview candidates and train new employees in their new positions, and
resulted in an estimated value of $2.2 million, which is being amortized over
five years. Goodwill which is related to the ongoing value of the acquired
communications networking business is being amortized over 20 years.

The Company expects to incur additional non-recurring charges during the
remainder of its 1996 fiscal year related to the elimination of duplicate
facilities, relocation and severance costs, and other integration costs. These
amounts have not yet been finalized and are not reflected in the accompanying
pro forma condensed combining statement of operations.

Note 2.   Loss Per Share

The pro forma combined primary loss per share has been computed based on the
weighted average number of common shares outstanding during the period, after
increasing the net loss for the dividend requirements on the Company's
outstanding $5.00 Cumulative Preferred Stock. Common stock equivalents are not
dilutive for the pro forma period presented. The exercise of the conversion
option on the 7% convertible subordinated note issued in the HLS acquisition is
not considered dilutive for purposes of calculating fully diluted loss per
share.

Note 3.   Pro Forma Adjustments

(a)  Reflects the elimination of Xyplex historical amortization expense and
     impairment loss totaling $33,679,000 and the additional amortization
     expense of $3,454,000 based upon the allocation of purchase price to
     intangible assets.

(b)  Reflects the elimination of Xyplex historical allocations of corporate
     expenses of $207,000.

(c)  Reflects the elimination of acquired in-process research and development
     which is directly a result of the acquisition.

     costs, incurred by the Company to fund the acquisition.
