NOTE A - BASIS OF PRESENTATION

         The accompanying condensed consolidated financial statements have
been prepared by the Company without audit. In the opinion of management,
all adjustments (including normal recurring accruals) considered necessary
for a fair presentation have been included. Operating results for the three
and six month periods ended April 30, 2003 are not necessarily indicative of
the results to be expected for the entire fiscal year.

         The accompanying unaudited condensed consolidated financial
statements have been prepared in accordance with generally accepted
accounting principles for interim financial statements and with the
instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly,
they do not include all of the information and footnotes required by
generally accepted accounting principles for complete financial statements.
For further information, refer to the consolidated financial statements and
footnotes thereto included in the Company's annual report to shareholders
for the year ended October 31, 2002.

NOTE B - EARNINGS PER SHARE

         Average diluted common shares outstanding include common stock
equivalents, which represent common stock options as computed based on the
treasury stock method. Average basic and diluted common shares outstanding
have been restated to reflect a three-for-two stock split effected by the
Company on October 31, 2002 in the form of a stock dividend.

         Basic earnings per share for the three months ended April 30, 2003
and 2002 is based on average basic common shares outstanding of 16,078 and
15,476, respectively. Diluted earnings per share for the three months ended
April 30, 2003 and 2002 is based on average diluted common shares
outstanding of 17,010 and 16,055, respectively.

         Basic earnings per share for the six months ended April 30, 2003
and 2002 is based on average basic common shares outstanding of 15,995 and
15,408, respectively. Diluted earnings per share for the six months ended
April 30, 2003 and 2002 is based on average diluted common shares
outstanding of 16,926 and 15,989, respectively.

NOTE C - STOCK-BASED COMPENSATION

         The Company applies Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees," and related interpretations in
accounting for all stock option plans. Accordingly, no compensation expense
has been recognized for stock option awards. The following table illustrates
the effect on net income from continuing operations and earnings per share
had the Company applied the fair value recognition provisions of Statement
of

NOTE G - OPERATIONAL RESTRUCTURING

         During the quarter ended July 31, 2002, the Company announced a
restructuring plan to improve both plant utilization and long-term
profitability. Under the plan, the Company's Blue Ash, Ohio and Olivette,
Missouri manufacturing locations will be closed during the year ending
October 31, 2003 with related production efforts being relocated to other
existing Company facilities. Emerging Issues Task Force No. 94-3 (ETIF
94-3), which was effective through December 31, 2002, provided specific
requirements as to the appropriate recognition of restructuring costs
associated with employee termination benefits and other exit costs. Employee
termination costs are recognized when benefit arrangements are communicated
to affected employees in sufficient detail to enable the employees to
determine the amount of benefits to be received upon termination. Other
costs resulting from the restructuring plan that

                                     8

<PAGE>

are not associated with or that do not benefit activities that will be
continued are recognized at the date of commitment to the plan subject to
certain conditions. For the cost to be accrued, it must not be associated
with or incurred to generate revenues after the commitment date, and must be
either incremental to other costs incurred prior to the commitment date or
represent amounts under a contractual obligation that existed prior to the
commitment date that will either continue after the plan is completed with
no economic benefit or which will result in a penalty to cancel the
obligation. Other costs directly related to the restructuring plan which are
not eligible for recognition at the commitment date, such as relocation and
other integration costs, are expensed as incurred. The plan will involve
terminating 113 employees, 60 of which had been terminated as of April 30,
2003.

         During the six months ended April 30, 2003, the Company recorded
the following costs in connection with this restructuring plan.

         During the quarter ended April 30, 2003, the Company announced an
additional restructuring plan under which the electronics assembly work
currently performed at the Company's Sanford, Florida facility of its
Systems & Electronics Inc. (SEI) subsidiary will be relocated to alternate
SEI facilities. Statement of Financial Accounting Standards No. 146 (SFAS
146), "Accounting for Costs Associated with Exit or Disposal Activities",
applies to all disposal activities initiated after December 31, 2002 and
prospectively nullifies EITF 94-3. SFAS 146 requires that a liability for
employee termination costs associated with an exit or disposal activity be
recognized when the liability is incurred. (EITF 94-3 had previously
required that a liability for such costs be recognized at the date of the
Company's commitment to an exit or disposal plan). In accordance with SFAS
146, the Company recorded restructuring expense of $1.2 million in the
quarter ended April 30, 2003 and anticipates that it will record an
additional $1.8 million of restructuring expense related to this plan,
substantially all of which will be recorded during the year ending October
31, 2003. The plan will involve terminating 147 employees, none of which had
been terminated as of April 30, 2003.

         During the three months ended April 30, 2003, the Company recorded
the following costs in connection with this restructuring plan.

NOTE H - DISCONTINUED OPERATIONS

         During the second quarter of 2002, the Company formally adopted a
plan to dispose of Engineered Specialty Plastics, Inc. (ESP), a wholly-owned
subsidiary representing the entirety of the Plastic Products business
segment. The Company completed the sale of ESP in the quarter ended April
30, 2003 to a private equity group. Consideration received by the Company
included $4.1 million of cash, a $3.3 million two-year note from the buyers
secured by the real property of ESP, and contingent consideration based upon
ESP's future revenues, net of a $0.3 million working capital adjustment
payable by the Company. In conjunction with the intended disposition of ESP,
the Company had previously recorded an estimated loss on disposal of
discontinued operations of $4.2 million to reduce the carrying value of
ESP's net assets to their estimated fair value less estimated selling costs.
The completion of the sale resulted in no adjustment to this $4.2 million
loss. The Company has reported the results of operations of ESP as
discontinued operations for the three and six months ended April 30, 2003
and 2002 in the Condensed Consolidated Statements of Income. All assets and
liabilities associated with ESP have been reclassified as assets and
liabilities of discontinued operations on the October 31, 2002 Condensed
Consolidated Balance Sheet. Certain information with respect to the
discontinued operations of ESP for the three and six month periods ended
April 30, 2003 and 2002 is as follows:

NOTE L - SUBSEQUENT EVENT

         Effective May 1, 2003, the Company acquired all of the outstanding
stock of Technical and Management Services Corporation (TAMSCO), a provider
of information technology logistics and digitization services and a designer
and integrator of telecommunication systems primarily for the U.S.
Department of Defense. The purchase price was $66.5 million in cash, which
the Company financed with short-term borrowings under its revolving credit
facility.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
         CONDITION AND RESULTS OF OPERATIONS.

CRITICAL ACCOUNTING POLICIES

         Revenues on long-term contracts performed within the Company's
Light Military Support Equipment, Heavy Military Support Equipment and
Electronics and Automation Systems segments, substantially all of which are
with the U.S. Government, are recognized under the percentage-of-completion
method and include a proportion of the earnings that are expected to be
realized on the contract in the ratio that production measures, primarily
labor, incurred bear to the estimated production measures for the contract.
Earnings expectations are based upon estimates of contract values and costs
at completion. Contracts in process are reviewed on a periodic basis.
Adjustments to revenues and earnings are made in the current accounting
period based upon revisions in contract values and estimated costs at
completion. Amounts representing contract change orders, claims and other
items are included in revenues, as recognized under the
percentage-of-completion method, only when these amounts can be reliably
estimated and realization is probable. Provisions for estimated losses on
contracts are recorded when identified.

         During the second quarter of 2002, the Company formally adopted a
plan to dispose of Engineered Specialty Plastics, Inc. (ESP), a wholly-owned
subsidiary representing the entirety of the Plastic Products business
segment. In conjunction with this plan, the Company recorded an estimated
loss on disposal to reduce the carrying value of ESP's net assets to their
estimated fair value less estimated selling costs. Accordingly, the Company
has reported the results of operations of ESP as discontinued operations for
the three and six months ended April 30, 2003 and 2002 in the Condensed
Consolidated Statements of Income. Additionally, all depreciation on the
property, plant and equipment of ESP was suspended as of the end of the
second quarter of 2002. The Company completed the sale of ESP in the second
quarter of 2003 with no resulting adjustment to the estimated loss on
disposal.

         During the third quarter of 2002, the Company announced a
restructuring plan to improve both plant utilization and long-term
profitability. Under the plan, the Company's Blue Ash, Ohio and Olivette,
Missouri manufacturing locations will be closed during the year ending
October 31, 2003 with related production efforts being relocated to other
existing Company facilities. Emerging Issues Task Force No. 94-3 (EITF 94-3)
provided specific requirements as to the appropriate recognition of
restructuring costs associated with employee termination benefits and other
exit costs. Employee termination costs are recognized when benefit
arrangements are communicated to affected employees in sufficient detail to
enable the employees to determine the amount of benefits to be received upon
termination. Other costs resulting from the restructuring plan that are not
associated with or that do not benefit activities that will be continued are
recognized at the date of commitment to the plan subject to certain
conditions. For the cost to be accrued, it must not be associated with or
incurred to generate revenues after the commitment date and must be either
incremental to other costs incurred prior to the commitment date, or
represent amounts under a contractual obligation that existed prior to the
commitment date that will either continue after the plan is completed with
no economic benefit or which will result in a penalty to cancel the
obligation. Other costs directly

                                     13

<PAGE>
<PAGE>

related to the restructuring plan which are not eligible for recognition at
the commitment date, such as relocation and other integration costs, are
expensed as incurred.

         During the quarter ended April 30, 2003, the Company announced an
additional restructuring plan under which the electronics assembly work
currently performed at the Company's Sanford, Florida facility of its
Systems & Electronics Inc. (SEI) subsidiary will be relocated to alternate
SEI facilities. Statement of Financial Accounting Standards No. 146 (SFAS
146), "Accounting for Costs Associated with Exit or Disposal Activities",
applies to all disposal activities initiated after December 31, 2002 and
prospectively nullifies EITF 94-3. SFAS 146 requires that a liability for
employee termination costs associated with an exit or disposal activity be
recognized when the liability is incurred. (EITF 94-3 had previously
required that a liability for such costs be recognized at the date of the
Company's commitment to an exit or disposal plan).

         The following analysis should be read in this context.


RESULTS OF OPERATIONS

         Consolidated net revenues from continuing operations increased
$33.3 million, or 36.3%, to $125.1 million in the second quarter of 2003
compared to $91.8 million in the second quarter of 2002. This increase was
primarily the result of $26.4 million of net revenues from Radian, Inc.
(Radian), which was acquired May 10, 2002, and from Universal Power Systems,
Inc. (UPSI), which was acquired June 27, 2002. Radian's most significant
contract, the Deployable Power Generation and Distribution System (DPGDS)
for the U.S. Air Force and U.S. Army contributed $13.3 million in revenues
during the quarter ended April 30, 2003. All other operating subsidiaries
contributed a combined 7.5% increase in net revenues during the quarter.
Gross profit from continuing operations for the three months ended April 30,
2003 increased $8.0 million, or 36.9%, to $29.8 million (23.8% of
consolidated net revenues) from $21.8 million (23.7% of consolidated net
revenues) in the comparable 2002 period. The increase in gross profit was a
result of the significant increase in net revenues. Selling, general and
administrative expense from continuing operations increased $4.2 million, or
40.4%, in the second quarter of 2003 to $14.5 million (11.6% of consolidated
net revenues) from $10.3 million (11.3% of consolidated net revenues) in the
second quarter of 2003. In addition, the Company recorded a restructuring
expense of $1.2 million in the quarter ended April 30, 2003 related to its
announced plan to relocate electronics assembly work currently performed at
the Company's Sanford, Florida facility of its Systems & Electronics Inc.
(SEI) subsidiary to alternate SEI facilities. As a result of the above,
income from continuing operations increased $2.7 million or 23.3% in the
quarter ended April 30, 2003 to $14.1 million from $11.5 million in the
second quarter of 2002.

         Consolidated net revenues from continuing operations increased
$63.6 million, or 34.8%, to $246.7 million in the six months ended April 30,
2003 compared to $183.1 million in the first half of 2002. This increase was
primarily the result of $55.3 million of net revenues from Radian and UPSI.
All other operating subsidiaries contributed a combined 4.5% increase in net
revenues during the six month period. Gross profit from continuing
operations for the six

                                     14

<PAGE>

months ended April 30, 2003 increased $15.2 million, or 36.6%, to $56.9
million (23.1% of consolidated net revenues) from $41.7 million (22.8% of
consolidated net revenues) in the comparable 2002 period. Selling, general
and administrative expense from continuing operations increased $7.7
million, or 39.0%, in the first half of 2003 to $27.4 million (11.1% of
consolidated net revenues) from $19.7 million (10.8% of consolidated net
revenues) in the prior year. As a result of the above and of the $1.2
million restructuring expense discussed above, income from continuing
operations increased $6.4 million, or 29.1%, in the six months ended April
30, 2003 to $28.4 million from $22.0 million in the first half of 2002.

         LIGHT MILITARY SUPPORT EQUIPMENT. Net revenues for the Light
Military Support Equipment segment increased by $31.2 million, or 83.4%, to
$68.6 million in the second quarter of 2003 from $37.4 million in the second
quarter of 2002 primarily due to the addition of $26.4 million in net
revenues from Radian and UPSI. All other operating subsidiaries within the
segment contributed a combined 12.8% increase in net revenues during the
quarter. For the six months ended April 30, 2003, net revenues for the
segment increased by $60.5 million, or 78.7%, to $137.5 million from $77.0
million in the first half of 2002. Radian and UPSI accounted for $55.3
million of this increase. Gross profit for the segment increased by $7.3
million, or 88.5%, in the second quarter of 2003 to $15.6 million (22.8% of
segment net revenues) from $8.3 million (22.2% of segment net revenues) in
the second quarter of 2002. Likewise, gross profit for the segment increased
by $12.1 million, or 69.1%, in the six months ended April 30, 2003 to $29.5
million (21.4% of segment net revenues) from $17.4 (22.6% of segment net
revenues) in the first half of 2002. Income from operations increased by
$3.2 million, or 73.7%, in the second quarter of 2003 to $7.6 million from
$4.4 million in the second quarter of 2002, and increased by $4.0 million,
or 41.0%, in the first half of 2003 to $13.7 million from $9.7 million in
the first half of 2002.

         HEAVY MILITARY SUPPORT EQUIPMENT. Net revenues for the Heavy
Military Support Equipment segment decreased by $2.9 million, or 8.5%, to
$31.5 million in the second quarter of 2003 from $34.4 million in the second
quarter of 2002. This decrease was primarily due to the completion of
deliveries for the M1000 semi-trailer in March 2003. M1000 contract revenues
totaled $4.1 million in the second quarter of 2003 compared to $7.0 million
in the quarter ended April 30, 2002. For the six months ended April 30,
2003, net revenues for the segment decreased by $2.8 million, or 4.3%, to
$62.6 million from $65.4 million in the first half of 2002, also due to
completion of the M1000 contract. Gross profit for the segment decreased by
$1.8 million, or 18.2%, in the second quarter of 2003 to $7.9 million (25.2%
of segment net revenues) from $9.7 million (28.2% of segment net revenues)
in the second quarter of 2002. For the six months ended April 30, 2003,
gross profit for the segment was $16.4 million (26.2% of segment net
revenues), which was unchanged from $16.4 million (25.0% of segment
revenues) in the first six months of 2002. Income from operations decreased
by $1.4 million, or 23.8%, to $4.3 million in the second quarter of 2003
from $5.7 million in the second quarter of 2002, and increased by $0.7
million, or 7.8%, in the first half of 2003 to $9.7 million from $9.0
million in the first half of 2002.

         ELECTRONICS AND AUTOMATION SYSTEMS. Net revenues for the
Electronics and Automation Systems segment increased by $5.0 million, or
25.2%, to $25.0 million in the second quarter of 2003 from $20.0 million in
the second quarter of 2002. This increase was

                                     15

<PAGE>
<PAGE>

primarily due to additional revenues from the Knight reconnaissance /
surveillance / target acquisition program and higher demand for the
segment's MSTAR radar product. For the six months ended April 30, 2003, net
revenues for the segment increased by $5.9 million, or 14.6%, to $46.6
million from $40.7 million in the first half of 2002. Gross profit for the
segment increased $2.4 million, or 65.2%, in the second quarter of 2003 to
$6.2 million (24.9% of segment net revenues) from $3.8 million (18.9% of
segment net revenues) in the second quarter of 2002. For the six months
ended April 30, 2003, gross profit for the segment increased $3.2 million,
or 40.5%, to $11.1 million (23.8% of segment net revenues) from $7.9 million
(19.4% of segment net revenues) in the first half of 2002. Increases in
gross profit and gross margin for the segment were a result of higher
revenue levels and a more favorable product mix. Income from operations
increased by $0.8 million, or 56.0%, in the second quarter of 2003 to $2.3
million from $1.5 million in the second quarter of 2002, and increased by
$1.7 million, or 51.5%, in the first half of 2003 to $5.0 million from $3.3
million in the first half of 2002. Increases in income from operations were
a result of significant gains in gross profit, offset by a $1.2 million
restructuring expense in both the quarter and six months ended April 30,
2003.

         Net interest expense decreased by $0.5 million to $0.2 million in
the second quarter of 2003 and by $0.9 million to $0.6 million in the six
months ended April 30, 2003. These decreases were a result of lower
outstanding borrowings, as well as the impact of lower interest rates. The
effective income tax rate was 39.0% for the three and six month periods
ended April 30, 2003 and 2002. As a result of the foregoing, net income from
continuing operations increased 29.2% to $8.5 million (6.8% of consolidated
net revenues) in the quarter ended April 30, 2003 as compared to $6.6
million (7.2% of consolidated net revenues) in the second quarter of 2002.
For the six months ended April 30, 2003, net income from continuing
operations increased 35.7% to $16.9 million (6.9% of consolidated net
revenues) from $12.5 million (6.8% of consolidated net revenues) for the
first half of 2002.

         During the second quarter of 2002, the Company formally adopted a
plan to dispose of ESP. The Company completed the sale of ESP in the quarter
ended April 30, 2003 to a private equity group. In conjunction with the
intended disposition of ESP, the Company had previously recorded an
estimated loss on disposal of discontinued operations of $4.2 million, $3.2
million of which was recorded in the quarter ended April 30, 2002. The
completion of the sale resulted in no adjustment to this $4.2 million loss.
In addition, the Company realized income (loss) from ESP operations, net of
income tax, of $0.2 million and $(0.1) million in the second quarter of 2003
and 2002, respectively, and of $0.3 million and $(0.5) million in the six
months ended April 30, 2003 and 2002, respectively.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

         In August 2001, the FASB issued SFAS No. 144, "Accounting for the

disposal activity. These include, but are not limited to, costs to terminate
a contract that is not a capital lease, costs to consolidate facilities or
relocate employees, and certain termination benefits provided to employees
that are involuntarily terminated under the terms of a one-time benefit
arrangement. The Company adopted SFAS 146 effective January 1, 2003.

         In December 2002, the FASB issued SFAS 148, "Accounting for Stock
Based Compensation - Transition and Disclosure - an Amendment of SFAS 123."
SFAS 148 provides additional transition guidance for those entities that
elect to voluntarily adopt the provisions of SFAS 123, "Accounting for Stock
Based Compensation." Furthermore, SFAS 148 mandates new disclosures in both
interim and year-end financial statements within the Company's Significant
Accounting Policies footnote. The Company adopted these disclosure
requirements for the year ended October 31, 2002 and has applied them to its
interim financial statements in 2003.

         In November 2002, the FASB issued Interpretation No. 45 (FIN 45),
"Guarantor's Accounting and Disclosure Requirements for Guarantees,
Including Indirect Guarantees of Indebtedness of Others." FIN 45 clarifies
disclosures regarding certain guarantees to be made by a guarantor in its
interim and annual financial statements. FIN 45 also clarifies that a
guarantor is required to recognize, at the inception of certain guarantees,
a liability for the fair value of the obligation undertaken in issuing the
guarantee, but does not prescribe a specific approach for subsequently
measuring the liability over its life. Recognition provisions of FIN 45 are
to be applied prospectively for guarantees issued or modified after December
31, 2002. The related disclosure requirements are effective for periods
ending after December 15, 2002. The Company adopted FIN 45 for the quarter
ended January 31, 2003.

LIQUIDITY AND CAPITAL RESOURCES

         On April 16, 2003, the Company completed the sale of ESP to a
private equity group. Consideration received by the Company included $4.1
million of cash, a $3.3 million two-year note from the buyers secured by the
real property of ESP, and contingent consideration based upon ESP's future
revenues, net of a $0.3 million working capital adjustment payable by the
Company.

         Effective April 23, 2003, the Company retired all borrowings under
its existing credit facility and entered into a new bank agreement which
provided a $125 million unsecured, revolving credit facility. Borrowings
under the new agreement, which expires April 23, 2007, are subject to
interest, at the Company's option, at either the Eurodollar rate plus an
applicable margin or at the prime rate plus an applicable margin. The margin
applicable to the Eurodollar rate varies from 0.875% to 1.625% and the
margin applicable to the prime rate varies from 0.0% to 0.25% depending upon
the Company's ratio of total indebtedness to earnings before interest,
taxes, depreciation and amortization (leverage ratio). As of April 30, 2003,
the Company had borrowings of $15.0 million against the new revolving credit
facility and a cash balance of $14.9 million.

         Effective May 1, 2003, the Company acquired all of the outstanding
stock of Technical and Management Services Corporation (TAMSCO), a provider
of information technology logistics and digitization services and a designer
and integrator of telecommunication systems primarily for the U.S.
Department of Defense. The purchase price was $66.5 million in cash, which
the Company financed with short-term borrowings under its revolving credit
facility.

         At April 30, 2003, the Company's working capital and ratio of
current assets to current liabilities were $13.5 million and 1.16 to 1 as
compared with $17.6 million and 1.18 to 1 at October 31, 2002. The Company
generated cash flow from continuing operations of $49.2 million in the six
months ended April 30, 2003 as compared to $29.0 million in the first six
months of 2002. Investment in property, plant and equipment totaled $5.3
million and $1.7 million for the first six months of 2003 and 2002,
respectively. $3.4 million of total capital expenditures for the six months
ended April 30, 2003 were incurred at the Company's Keco Industries, Inc.
subsidiary and relate to the Company's previously discussed restructuring
plan. The Company anticipates that capital expenditures in 2003 should not
exceed $7.0 million. Management believes that cash flow generated from
operations, together with the available line of credit, will provide the
necessary resources to meet the needs of the Company in the foreseeable
future.

         There have been no material changes in the total contractual and
contingent obligations included in the Company's annual report to
shareholders for the year ended October 31, 2002.

BUSINESS AND MARKET CONSIDERATIONS

         Approximately 95% of consolidated net revenues from continuing
operations for the six months ended April 30, 2003 were directly or
indirectly derived from defense orders by the U.S. government and its
agencies. As of April 30, 2003, the Company's funded backlog of orders
totaled $431.0 million, with related customer options of an additional
$658.3 million.

         Management continues to pursue potential acquisitions, primarily of
those companies providing strategic consolidation within the defense
industry such as TAMSCO.

FORWARD-LOOKING STATEMENTS

         In addition to historical information, this report includes certain
forward-looking statements within the meaning of Section 27A of the
Securities Act of 1933, as amended, and Section 21E of the Securities
Exchange Act of 1934, as amended, which are intended to be covered by the
safe harbors created thereby. The forward-looking statements involve certain
risks and uncertainties, including, but not limited to acquisitions,
additional financing requirements, the decision of any of the Company's key
customers (including the U.S. government) to reduce or terminate orders with
the Company, cutbacks in defense spending by the U.S. government and
increased competition in the Company's markets, which could cause the
Company's actual results to differ materially from those projected in, or
inferred by, the forward-looking statements.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT
         MARKET RISK.

         At October 31, 2002, the Company's derivative contracts consisted
only of interest rate swaps used by the Company to convert a portion of its
variable rate long-term debt to fixed rates. These contracts expired in
November 2002. At April 30, 2003, the Company had no derivative contracts.




ITEM 4.  CONTROLS AND PROCEDURES.

         Within the 90 days prior to the filing date of this report, the
Company carried out an evaluation, under the supervision and with the
participation of the Company's management, including the Company's Chief
Executive Officer and Chief Financial Officer, of the effectiveness of the
design and operation of the Company's disclosure controls and procedures as
defined in Rules 13a-14(c) and 15d-14(c) under the Securities Exchange Act
of 1934, as amended (the "Exchange Act"). Based upon the evaluation, the
Company's Chief Executive Officer and Chief Financial Officer concluded that
the Company's disclosure controls and procedures are effective. Disclosure
controls and procedures are controls and procedures that are designed to
ensure that information required to be disclosed in Company reports filed or
submitted under the Exchange Act is recorded, processed, summarized and
reported within the time periods specified in the Securities and Exchange
Commission's rules and forms.

         There have been no significant changes in the Company's internal
controls or in other factors that could significantly affect those controls
subsequent to the date this evaluation was carried out, including any
corrective actions with regard to significant deficiencies and material
weaknesses.
