Independent auditors’ report to Federal Signal Corporation

We have audited the accompanying combined balance sheet and the combined profit and loss account, cash flow statement and the accompanying notes of the PIPS Technology Division of Federal Signal Corporation (the “Division”) for the year ended 31 December 2006.

Respective responsibilities of directors and auditors

These financial statements are the responsibility of the Division’s management; our responsibility is to express an opinion on these financial statements based on our audit.

Basis of audit opinion

We conducted our audit in accordance with auditing standards generally accepted in the United States of America. 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 consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

Without qualifying our opinion, we draw attention to the fact that, as described in Note 1, the PIPS Division has not operated as a separate group. These combined financial statements may not be indicative of results that would have occurred if the PIPS Division had been a separate stand-alone group during the year presented or of future results of the PIPS Division. We also draw attention to the basis of preparation of these financial statements in Note 1.

Opinion

In our opinion, the accompanying combined balance sheet and the combined profit and loss account, cash flow statement, and the accompanying notes present fairly in all material respects, the financial position of the PIPS Technology Division of Federal Signal Corporation (the “Division”) at 31 December 2006, and the results of its operations and its cash flows for the year then ended, in conformity with accounting principles generally accepted in the United Kingdom modified as described in the notes.

1 Accounting policies

Basis of accounting

The financial statements are prepared under the historical cost convention and in accordance with applicable United Kingdom Accounting Standards. A summary of the more important accounting policies are as follows:

Basis of combination

The combined profit and loss account and combined balance sheet relate to the financial statements of the PIPS Technology Division (“the Division”). The Division comprises the combined financial statements of PIPS Technology Limited and PIPS Technology Inc. The companies operate independently but are under common control. Combined entity results are not indicative of results that would have occurred if the Division had been a stand alone legal entity during the year presented. The combination has been effected by aggregating the two companies’ results, balance sheets and cash flows for the year ended 31 December 2006. Intra-division sales and profits are eliminated on combination. PIPS Technology Inc’s accounts are translated from dollars to sterling using a period-end rate for the balance sheet and an average rate for the profit and loss account.

Turnover

Turnover represents sales to external customers at invoiced amounts less value added tax or local taxes on sales.

Depreciation

Depreciation is provided to write off the cost, less estimated residual values, of all tangible fixed assets, evenly over their expected useful lives. It is calculated at the following rates:

UK
Leasehold improvements	10% straight line basis
Plant and machinery	20 — 25% straight line basis
Motor vehicles	25% straight line basis
Fixtures and fittings	20% straight line basis
Office equipment	20 — 33% straight line basis
US
Software	3 year straight line basis
All other	3 — 5 years double declining balance basis

Stocks

Stocks are valued at the lower of cost and net realisable value. Cost is based on the cost of purchase on a first in, first out basis. Net realisable value is based on estimated selling price less additional costs to completion and disposal.

Foreign currency

Foreign currency transactions are translated into sterling at the rates ruling when they occurred. Foreign currency monetary assets and liabilities are translated at the rates ruling at the balance sheet dates. Any differences are taken to the profit and loss account.

Research

Expenditure on research and development is charged to the profit and loss account in the year in which it is incurred.

1 Accounting policies (continued)

Deferred taxation

Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the balance sheet date, except that:

• deferred tax is not recognised on timing differences arising on revalued properties unless the Division has entered into a binding sale agreement and is not proposing to take advantage of rollover relief; and

• the recognition of deferred tax assets is limited to the extent that the Division anticipates making sufficient taxable profits in the future to absorb the reversal of the underlying timing differences.

Deferred tax balances arising from underlying timing differences in respect of tax allowances on industrial buildings are reversed if and when all conditions for retaining those allowances have been met.

Deferred tax balances are not discounted.

Share-based payment

When share options are awarded to employees, the fair value of the options at the date of grant is charged to the income statement over the vesting period. Non-market vesting conditions are taken into account by adjusting the number of equity instruments expected to vest at each balance sheet date so that, ultimately, the cumulative amount recognised over the vesting period is based on the number of options that eventually vest. Market vesting conditions are factored into the fair value of the options granted. As long as all other vesting conditions are satisfied, a charge is made irrespective of whether the market vesting conditions are satisfied. The cumulative expense is not adjusted for failure to achieve a market vesting condition.

Where the terms and conditions of options are modified before they vest, the increase in fair value of the options, measured immediately before and after the modification, is also charged to the income statement over the remaining vesting period.

Where equity instruments are granted to persons other than employees, the income statement is charged with the fair value of goods and services received.

Leased assets

Where assets are financed by leasing agreements that give rights approximating to ownership (finance leases), the assets are treated as if they had been purchased outright. The amount capitalized is the present value of the minimum lease payments payable during the lease term. The corresponding leasing commitments are shown as amounts payable to the lessor. Depreciation on the relevant assets is charged to the profit and loss account.

Lease payments are analysed between capital and interest components. The interest element of the payment is charged to the profit and loss account over the period of the lease and is calculated so that it represents a constant proportion of the balance of capital repayments outstanding. The capital part reduces the amounts payable to the lessor.

All other leases are treated as operating leases. Their annual rentals are charged to the profit and loss account on a straight-line basis over the term of the lease.

Pension costs

The Division operates two defined contribution pension schemes, one in the UK and one in the US. Pension contributions are charged to the profit and loss account in the period in which they become payable. These contributions are invested separately from the Division’s assets. Contributions from the Division amounted to £34,672. Contributions of £11,567 were accrued but unpaid at the year end.

Warranty provision

Where products are sold which are subject to warranties, a provision is recognised for the best estimate of the costs of making good under the warranty provision for products sold before the balance sheet date.

25. Ultimate controlling party

The directors consider that the Division was under the control of A.K. Sefton at 31 December 2006. The ultimate controlling party is now considered to be Federal Signal Corporation as a result of its acquisition of the Division in 2007.

26. Summary of differences between U.K. and U.S. generally accepted accounting principles (‘GAAP’)

The accompanying combined financial statements of the Division have been prepared in accordance with generally accepted accounting principles in the United Kingdom (“U.K. GAAP”). As a result, the Division’s financial statements may differ substantially from financial statements prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”). The Division was not required to prepare financial statements in accordance with US GAAP as of 31 December 2006.

The following is a summary of certain differences between UK GAAP and US GAAP. The discussion below should not be taken as an exhaustive list of all differences in accounting, disclosure, presentation or classification that could affect the manner in which transactions or events are presented in the Division financial statements. In addition, footnote disclosures under US GAAP (including disclosure of related party transactions) can be more extensive than those required under UK GAAP.

PIPS Technology Division
Notes to the financial statements
For the year ended 31 December 2006 (continued)

Presentation of Financial Statements

There are a number of presentation differences between UK GAAP and US GAAP which affect the classification of amounts reported in the Combined Statement of Operations, Combined Balance Sheet and Cash Flow. Such differences include the following —

Statement of Operations

Under UK GAAP, the Division reports its combined profit and loss account to include costs related to raw materials and consumables, staff, depreciation, amortisation of goodwill and other external expenses. Under US GAAP, expenditures must be presented by function. As such expenses would have been reclassified to be reported as cost of sales, selling and advertising, and general and administrative expenses.

Statement of Cash Flows

There are certain differences from UK GAAP to US GAAP with regard to the classification of items within the cash flow statement and with regard to the definition of cash and cash equivalents. In accordance with UK GAAP, cash flows are separately presented for operating activities, returns on investments and servicing of finance, taxation, capital expenditures and financial investment, acquisitions and disposals, equity dividends paid, management of liquid resources and financing. In addition, cash includes overdrafts, excludes cash equivalents but includes Restricted Cash. Under US GAAP, cash flows are classified under operating activities (including cash flows from taxation and returns on investments and servicing of finance), investing activities and financing activities. Cash also includes cash equivalents with an original maturity of three months or less and would exclude overdrafts.

Tax

UK GAAP requires full provision to be made for deferred tax assets and liabilities that arise from timing differences between the recognition of gains and losses in the financial statements and their recognition in the tax computation. Tax is provided based on substantially enacted rates. Deferred tax assets are recognised only to the extent that it is considered more likely than not that there will be suitable taxable profits from which the underlying timing differences can be deducted. Under US GAAP, deferred taxation is provided on all temporary differences between the financial statements carrying amounts of all existing assets and liabilities and their respective tax basis. Tax is provided based on enacted rates. Deferred tax is provided subject to a valuation allowance to reduce the deferred tax assets to the amount which more likely than not will be realised in the future tax returns.
