SOUTHWEST WATER COMPANY AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

Note 1. – Basis of Presentation

Southwest Water Company and its subsidiaries (collectively referred to in this report as “Southwest,” the “Company,” “we,” “us” or “our” except where the context otherwise requires) provide a broad range of services including water production, treatment and distribution; wastewater collection and treatment; utility billing and collection; utility infrastructure construction management; and public works services. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information and with the instructions to Form 10-Q and with Rule 10-01 of Regulation S-X; accordingly, they do not include all information and notes required by US GAAP for complete financial statements. Except as disclosed herein, there have been no material changes in the information disclosed in the notes to the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2004 (the “2004 Annual Report”). The unaudited condensed consolidated financial statements reflect all adjustments which, in our opinion, are necessary to present fairly the financial position of Southwest as of September 30, 2005, and our results of operations for the three and nine months ended September 30, 2005 and 2004 and our cash flows for the nine months ended September 30, 2005 and 2004.

The results of interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year.

Southwest Water Company was incorporated in California in 1954 and reincorporated in Delaware in 1988.

Certain reclassifications have been made to the prior period financial statement presentation to conform to the current period presentation including the reclassification related to discontinued operations described in Note 9.

Note 2. – Earnings Per Share

We report earnings per share (“EPS”) by computing “basic EPS” and “diluted EPS.” Basic EPS measures our performance over the reporting period by dividing net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS measures our performance over the reporting period after giving effect to all potentially dilutive common shares that would have been outstanding if the dilutive common shares had been issued. Stock options, convertible debentures and warrants give rise to potentially dilutive common shares. In July 2001, we issued $20.0 million of 6.85% fixed-rate convertible subordinate debentures. The debentures are convertible at any time prior to maturity in 2021, unless previously redeemed, at a conversion price of $11.569. At such time as the assumed conversion of the debentures has a dilutive effect on earnings per share, the debentures will be included in the calculation of diluted earnings per share, after adjusting net income for the after-tax effect of the debenture interest expense.

We declared a 5% stock dividend on January 3, 2005. All per share amounts and numbers of shares outstanding reflect this dividend.

Dividend Reinvestment and Stock Purchase Plan (“DSPP”): We have a stockholder-approved DSPP where existing stockholders may purchase additional shares of our common stock by reinvesting all or a portion of the dividends paid on owned shares of stock and by making optional cash payments of not less than $25 up to a maximum of $10,000 per month. We may permit optional cash payments in excess of this maximum if we approve a request for waiver. New investors may join the plan by making an initial investment of not less than $250 up to a maximum of $10,000. We may permit initial investments in excess of this maximum if we approve a request for waiver. For 2005, the purchase price for newly issued shares of common stock purchased directly from us will be the market price less a discount of 5%. The discount may range from 0% to 5% as determined from time to time by us.

Under the DSPP, we issued 317,063 and 363,289 shares to shareholders during the three and nine months ended September 30, 2005, respectively. At September 30, 2005, 500,000 shares had been authorized for issuance under the DSPP and approximately 136,711 shares remain available for issuance.

The following table is a reconciliation of the numerators (income or loss) and denominators (shares) used in both basic and diluted EPS calculations:

Note 3. –Stock-Based Compensation Plans

At September 30, 2005, Southwest had three stock-based compensation plans: a Stock Option Plan (“SOP”), a Director Stock Option Plan (“DOP”), and an Employee Stock Purchase Plan (“ESPP”). In accordance with the provisions of Statement of Financial Accounting Standards (“SFAS”) No. 123, Accounting for Stock-Based Compensation, the fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions used for grants in 2005 and 2004:

	Nine Months Ended
	September 30,
	2005		2004
Dividend yield	1.7	%	1.3	%
Expected volatility	24.3	%	24.4	%
Risk-free interest rate	4.1	%	3.7	%
Expected life in years	5.7		6.0

Compensation expense arising from stock option grants as determined using the Black-Scholes fair value option model was as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2005		2004		2005		2004
	(in thousands)				(in thousands)
Stock-based compensation expense	$	236	$	307	$	702	$	755

A combined summary of shares authorized and available for issuance under the SOP, the DOP and ESPP as of September 30, 2005, was as follows:

	SOP	DOP	ESPP	Total
	(in thousands)
Shares authorized for issuance	3,031	666	1,197	4,894
Shares available for issuance	988	300	875	2,163

Following is a combined summary of changes in the status of the SOP, the DOP and warrants during the nine months ended September 30, 2005:

			Weighted

$	1.50	$	15.00	2,545	3.9	$	8.64	1,564	$	7.14

Employee Stock Purchase Plan: We have a stockholder-approved ESPP that allows eligible employees to purchase our common stock through payroll deductions of up to 10% of their salary (not to exceed $25,000 per year). The purchase price of the stock is 90% of the lower of the share price as calculated at the beginning and end of each three-month offering period. Under the ESPP, we issued 7,032 and 18,630 shares to employees during the three and nine months ended September 30, 2005, respectively. At September 30, 2005, 1,197,000 shares had been authorized for issuance under the ESPP and approximately 875,000 shares remain available for issuance.

Note 4. – Post Retirement Benefits

The Company has a non-qualified supplemental executive retirement plan (“SERP”) for certain key executive officers. The following table sets forth the components of the net periodic benefit costs for the SERP:

	Three Months Ended September 30,				Nine Months Ended September 30,

	$	58	$	73	$	174	$	165

Note 5. – Operating Segments

Southwest has two reportable segments: the Utility Group and the Services Group. We have not changed the basis of presentation or measurement of segment profit or loss from that reported in our 2004 Annual Report.

The Utility Group owns a regulated water utility in California, regulated water and wastewater utilities in New Mexico, Oklahoma and Texas, and a wastewater utility in Alabama whose rates are determined through an agreement with county authorities. Revenues result from the production and distribution of water and the collection and treatment of sewage for residential, business, industrial and public authority customers. State, federal and local agencies issue regulations regarding standards of water quality, safety, environmental and other matters which affect these operations. The rates our regulated utility subsidiaries charge for water and wastewater services are established by state or county authorities.

The Services Group operates and manages water and wastewater treatment facilities owned by cities, public agencies, municipal utility districts, private entities and investor-owned utilities (including Utility Group affiliates). Revenues are earned by providing operations and maintenance services under contracts with these clients. The Services Group also provides construction management and utility billing services. In June 2005, we sold our submetering subsidiary which provided utility billing and collection services for multi-family residential properties such as apartment buildings and which was previously recorded as a part of the Services Group (see Note 9).

The tables below present information about the operations of each reported segment for the three and nine months ended September 30, 2005 and 2004:

(1) In addition to services provided to external customers, certain companies in our Services Group provide construction, operations, and maintenance services to companies in our Utility Group. In accordance with SFAS No. 71, Accounting for the Effects of Certain Types of Regulation, the Company does not eliminate the intersegment profit on sales to affiliated utilities when the sales price is reasonable and it is probable that, through the rate making process, future revenue approximately equal to the sales price will result from the regulated affiliate’s use of the services. Intersegment revenue was approximately $7.9 million and $5.4 million for the three months ended September 30, 2005 and 2004, respectively. Intersegment revenue was approximately $22.4 million and $10.3 million for the nine months ended September 30, 2005 and 2004, respectively.

(2) “Corporate and Other” consists primarily of costs that include headquarters expenses and any corporate functional departments whose costs are not allocated to reportable segments.

(3) Services Group amounts have been adjusted to reflect the discontinued operations from the sale of our submetering subsidiary as discussed in Note 9.

Note 6. – Seasonality and Weather

As our businesses are affected by weather, therefore the results of operations for one quarter do not indicate results to be expected in another quarter.

Our Utility Group water operations are seasonal, as rainfall and weather conditions affect water consumption. The second and third quarters of each year typically account for the highest volume of water consumption when weather tends to be hot and dry and a significant part of our water sales are for outside usage such as landscape and pools. Drought conditions may result in lower revenue due to consumer conservation efforts and a shortage of water. Drought conditions may also result in increased water costs to us, which could adversely affect our profitability. Conversely, unusually wet conditions may result in decreased customer demand, lower revenues and lower profit.

While our Services Group operations are not as seasonal, they are subject to the effects of weather. Heavy rainfall or storm conditions may limit our ability to perform certain billable work such as pipeline maintenance, manhole rehabilitation, construction and other outdoor services. Severe weather conditions may also result in additional labor and material costs as we meet the terms of our operations and maintenance contracts. Depending on the specific contractual terms, this additional work may be billable to certain clients. A significant portion of the revenues by our Texas subsidiaries are earned under time and materials contracts in which revenues are affected by weather and rainfall.

Note 7. – Commitments, Contingencies and Restrictions

Commitments Under Acquisition Agreements

We own 90% of the outstanding common stock of Operations Technologies, Inc. (“OpTech”). We have the right to acquire the remaining 10% of OpTech beginning in August 2006 based on a formula relating to the profitability of OpTech. The minority owner has the option to sell the remaining 10% of OpTech to the Company using the same formula. However, the selling price cannot be less than $1 million.

We have an 80% interest in Windermere Utility Company (“Windermere”) in Texas. We have the right to acquire the remaining 20% ownership in Windermere for a purchase price of $6 million payable in Southwest’s common stock at any time when the market value of our common stock increases to $12.96 per share (as adjusted for stock splits and dividends). This right has not been exercised by SWWC. The minority owner of Windermere has the right to put the remaining 20% to us beginning in October 2005 for up to approximately 860,000 shares of Southwest’s common stock, but no fewer than 463,000 shares both adjusted for stock splits and dividends, depending on the prevailing stock price, with a value not to exceed $6 million. The minority owner has notified us of his intent to exercise his right to put the remaining 20% to us in exchange for common stock in accordance with the terms of our agreement.

Commitments Under Divestiture Agreements

As part of the agreement to sell our submetering subsidiary (see Note 9), we were required to calculate a working capital adjustment, adjust for the net loss of customers and complete a transmitter replacement program. These items were estimated and recorded as liabilities in the 2^nd quarter of 2005. Adjustments to the sales price arising from these items are to be paid or collected through an escrow account of approximately $1.2 million that was established and recorded in other current assets at the close of the transaction in June 2005. As of September 30, 2005, we have accrued for all expected expenses. The escrow account will be closed in March 2006 and any amounts remaining on deposit at that time will be remitted to us.

Commitments Under Long-term Service Contracts

In September 2002, we won a bid to facilitate the engineering and construction of a reverse osmosis water treatment system in San Juan Capistrano, California, for the Capistrano Valley Water District (“CVWD”). The project included the drilling of several new wells and the development of associated water lines. We entered into subcontractor agreements with an engineering firm and a large construction firm to fulfill significant obligations of this contract.

During construction of the CVWD plant, we received payments upon completion of construction phases. Construction of the plant commenced in December 2002 and was substantially completed as of September 30, 2005. The plant became primarily operational in 2004 and the Company now operates and maintains the facility under a separate 20-year operations and maintenance contract.

In January 2003, we obtained an unsecured line of credit facility from a commercial bank that was used to issue a $3.4 million standby letter of credit as collateral for performance under a contract to design and construct the CVWD plant. This standby letter of credit was in force for the construction period of the project. On April 1, 2005, the standby letter of credit was transferred to the New Credit Facility (see Note 10) and the prior line of credit was cancelled.

As part of the financing of this project, the CVWD issued insured municipal bonds. We entered into an agreement with the bond insurer to guarantee our performance under the CVWD contract, subject to certain liability limits to the bond insurer in the event of a default. Such liability limits will not exceed an amount equal to $6.0 million during the construction period of the project, and afterwards, during the 20-year operation of the facility, the liability limits will not exceed an amount equal to $4.0 million plus an amount no greater than the replacement cost of the reverse osmosis filtration unit within the facility, estimated to be approximately $1.5 million.

Legal Proceedings

Southwest and a subsidiary were named as defendants in several lawsuits alleging various injuries as a result of water contamination in the San Gabriel Valley Main Basin. The California Supreme Court has ruled that the plaintiffs cannot challenge the adequacy of the water quality standards established by California Department of Health Services and the United States Environmental Protection Agency (“EPA”) but can sue us if they can prove that we served water that did not meet those standards. In August 2004 a trial court dismissed the case against us, finding that there was no evidence that we violated any water quality standards. The plaintiffs appealed the dismissal to the Court of Appeals for the State of California, Second Appellate District, where the matter is pending. To date, liability insurance carriers have absorbed the costs of defense of the lawsuits.

On May 5, 2005, one of the Company’s operating subsidiaries received a subpoena to provide records to a grand jury. The requested records relate to the operations of the San Simeon wastewater treatment plant in California for the period January 2002 to present. The facility was also served with search warrants executed by the EPA. The Company’s subsidiary has operated this facility since September 2004. The Company is cooperating with the investigation and is also performing its own internal investigation.

On May 18, 2005, the EPA executed a search warrant at one of the Company’s operating subsidiaries in Texas. The search warrant sought information relating to the subsidiary’s laboratory operations. The Company is cooperating with the investigation and is also performing its own internal investigation.

Southwest Water Company and its subsidiaries are subject to litigation arising in the ordinary course of operations. We believe the ultimate resolution of all matters that have been brought to our attention will not materially adversely affect our consolidated financial position, results of operations or cash flows.

Groundwater Settlement

One of the water sources for our California water utility has been affected by the presence of certain groundwater contaminants. These contaminants consist mainly of chemicals disposed of by various industrial companies in the 1940s and 1950s. In 2001 and 2002, this contamination necessitated the removal from service of a number of our wells, and we purchased replacement water at a cost substantially higher than the cost of water pumped from our own wells.

As a result of this contamination, under the terms of an agreement with the responsible parties, we have received payments from these parties, and we expect to continue to receive payments until completion of remediation or until our production capacities have been restored. These payments represent the incremental cost of purchasing water over the cost that would have been incurred by us to pump water from our wells. Our agreement with the responsible parties provided for ongoing reimbursement of our excess water costs and, as such, we bill and collect reimbursements monthly. These monthly reimbursements are recorded as a reduction to

operating expenses-utility group. During the nine months ended September 30, 2005 and 2004, these reimbursements were approximately $2.3 million and $2.8 million, respectively.

The settlement agreement also provides for contributions by the responsible parties to construct new wells and to develop additional interconnections with nearby water sources. Funds from the settlement agreement will also be used to develop long-term solutions that will potentially enable us to use our own less costly groundwater supplies in the future. These contributions, recorded as contributions in aid of construction (“CIAC”), were approximately $0.1 million and approximately $0.4 million for the nine months ended September 30, 2005 and 2004, respectively.

Note 8. – Acquisitions

In March 2005, we completed the acquisition of a contract operations company located in Shelby County, Alabama. The aggregate purchase price was approximately $2.5 million, of which $0.7 million was deferred, plus liabilities we assumed in the amount of approximately $1.2 million. We incurred transactions cost of approximately $0.2 million.

In September 2005, we completed the acquisition of a wastewater system located in Shelby County, Alabama. The aggregate purchase price and related transaction costs were approximately $8.5 million and $0.1 million, respectively.

The acquisitions were asset purchases and the assets acquired and liabilities assumed have been recorded at their estimated fair values. The difference between the total purchase price and the fair value of the net assets acquired of approximately $0.9 million was recorded as goodwill. The purchase price allocations are preliminary and may change upon the completion of the final valuations of the net assets acquired.

Note 9. – Discontinued Operations

In June 2005, we completed the sale of our submetering subsidiary that provided utility billing and collection services for multi-family residential properties in our Services Group. The sales price was approximately $12.0 million. We received approximately $10.8 million in cash and approximately $1.2 million of the sales price was placed into an escrow account and is included in other current assets in the accompanying consolidated financial statements. As part of the sale, we provided certain representations and warranties that are customary in sales transactions and committed to a specified level of working capital of the subsidiary as of the closing date. We expect to receive the escrow balance in March 2006. We utilized the net proceeds from the sale of approximately $10.8 million (less transaction costs of $1.0 million) to subsequently repay our bank lines of credit. The sale of our sub-metering subsidiary will not affect the operations of our remaining operating subsidiaries.

In the second quarter we recorded a loss from discontinued operations (net of income tax benefit of approximately $0.7 million) of approximately $1.2 million and a loss on sale of stock of approximately $3.7 million (net of income tax benefit of approximately $0.3 million).

Note 10. - Debt Obligations

In April 2005, we established the New Credit Facility. The New Credit Facility provides for a $100 million revolving credit facility, which includes a $40 million letter of credit subfacility and a $10 million swingline subfacility. The New Credit Facility contains customary covenants, as well as customary events of default. Certain of our subsidiaries have guaranteed our obligation to repay borrowings under the New Credit Facility.

Loans under the New Credit Facility (other than swingline loans) will bear interest at a rate equal to (i) a Eurodollar rate plus the applicable margin (as defined in the New Credit Facility), or (ii) a base rate (as defined) minus the applicable margin. At September 30, 2005, we had approximately $27 million of outstanding borrowings under our New Credit Facility and the adjusted average borrowing rate was approximately 4.8%. The New Credit Facility replaced our lines of credit which had provided for up to $50 million of borrowings and we used the New Credit Facility to repay amounts outstanding under those lines of credit. As of September 30, 2005, we were in compliance with all applicable covenants under the New Credit Facility.

In January 2003, we received a $3.4 million line of credit with one of our commercial banks that we used to issue a standby letter of credit in that amount as collateral for performance under a contract to design and construct the CVWD plant. On April 1, 2005, the standby letter of credit was transferred to the New Credit Facility, and the separate line of credit was cancelled.

Overview

Southwest Water Company and subsidiaries (“Southwest,” “we,” “us,” “our” or the “Company,” unless the context otherwise requires) provide a broad range of water and wastewater services including water production, treatment and distribution; wastewater collection and treatment; utility billing and collection; utility infrastructure construction management; and public works services. We provide services to more than two million people. Our business is segmented into two operating groups: our Utility Group and our Services Group.

Our Services Group operates our contract service businesses in which we operate and maintain water supply and wastewater facilities owned by cities, public agencies, municipal utility districts, private entities and investor-owned utilities (including Utility Group affiliates) primarily in Alabama, California, Colorado, Georgia, Mississippi, New Jersey, New Mexico, South Dakota and Texas. While state and federal agencies issue regulations regarding standards of water quality, safety, environmental and other matters which affect these operations, our Services Group prices are not subject to regulation. We also provided utility billing and collection services.

In July 2004, we acquired a Texas regulated water and wastewater utility consisting of a collection of 87 rural water systems and 11 wastewater systems serving approximately 21,000 water connections and 3,500 wastewater connections from Tecon Water Holdings, L.P. for approximately $66 million, and renamed the utility Monarch Utilities, Inc. (“Monarch”).

In March 2005, we completed the acquisition of the assets of a contract operations company located in Shelby County, Alabama. The aggregate purchase price was approximately $2.5 million, of which $0.7 million was deferred, plus liabilities we assumed in the amount of approximately $1.2 million. We incurred transactions cost of approximately $0.2 million.

In June 2005, we completed the sale of our submetering subsidiary that provided utility billing and collection services for multi-family residential properties. The sale price was approximately $12.0 million. We received approximately $10.8 million in cash, and approximately $1.2 million of the sales price was placed into an escrow account. We incurred transaction costs of approximately $1.0 million to complete the sale and our net proceeds on the sale of our submetering subsidiary were approximately $9.8 million.

In the second quarter of 2005, we recorded a loss from discontinued operations (net of income tax benefit of approximately $0.7 million) of approximately $1.2 million and a loss on sale of stock of approximately $3.7 million (net of income tax benefit of approximately $0.3 million) in connection with the sale of our submetering subsidiary.

Effects of Hurricanes Katrina and Rita

Hurricanes Katrina and Rita affected the Gulf Coast region of the United States during the third quarter of 2005 causing significant damage. Our Services Group provides contract operations and maintenance services to clients in Mississippi and Texas, among other states.

The water and wastewater infrastructure for five clients we service in Mississippi was disabled by Katrina. The contracts with our clients provide that we can incur and bill additional expenses during an emergency situation to restore water supply and wastewater treatment services to customers. In addition, our clients requested we assist with the removal of debris to enable access for emergency vehicles and residents. We incurred approximately $622,000 of overtime labor costs and emergency out-of-pocket operating expenses related to these emergency recovery efforts. These costs were reflected as operating expenses in the third quarter of 2005. We have billed (or will bill in certain cases) our clients approximately $536,000 to $700,000 for these emergency services and we are assisting our clients in requesting reimbursement from the Federal Emergency Management Agency (“FEMA”) pursuant to guidelines established in FEMA’s Applicant Handbook. We recognized revenues of $500,000 based on the revenue recognition criteria set forth in Staff Accounting Bulletin No. 104, Revenue Recognition with respect to these costs. Additional revenues, if any, resulting from billings to our clients beyond $500,000 will be recognized if and when collection is reasonably assured. The $500,000 we have billed for these emergency services is reflected in trade accounts receivable as of September 30, 2005.

We also incurred approximately $64,000 of costs related to preparing for Hurricane Rita, principally temporary infrastructure relocation expenses. These costs were recorded as an operating expense during the third quarter of 2005 and are not reimbursable by FEMA or recoverable through insurance.

Adoption of Share-Based Payment (SFAS 123R)

In December 2004, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 123 (revised December 2004), Share-Based Payment (“SFAS 123R”). This Statement is a revision of SFAS No. 123. SFAS 123R establishes standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services. SFAS 123R is effective for the Company as of the beginning of the first annual reporting period that begins after June 15, 2005. The

Company has already adopted SFAS No. 123, and management believes the impact of the adoption of SFAS 123R on the Company’s consolidated financial statements will not be material.

Discussion of Results of Operations for Three Months Ended September 30, 2005 and 2004

Revenues

Utility Group

Utility Group revenues are derived from the production and distribution of water and the collection and treatment of sewage for residential, industrial and commercial use. Our Utility Group results of operations are seasonal, as rainfall and weather conditions affect water consumption. In our service areas, the second and third quarters of each year typically account for the highest volume of water consumption when weather tends to be hot and dry. Drought conditions may result in lower revenue due to consumer conservation efforts and a shortage of water. Drought conditions may also result in increased water costs to us, which could adversely affect our profitability. Conversely, unusually wet conditions may result in decreased customer demand, lower revenues and lower profit in our Utility Group operations.

Revenues in the Utility Group increased approximately $0.9 million, or 4%, to $23.3 million during the three months ended September 30, 2005, from $22.4 million during the same period of the prior year. The increase in Utility Group revenue was primarily due to the following:

1. A $0.8 million increase in revenues attributable to Monarch Utility which we acquired in mid-July 2004.

2. An increase of $0.3 million due to higher volume and increased number of connections severd by our New Mexico and other Texas utilites.

3. An increase in rates of approximately $0.3 million at our California utility.

4. These increases were partially offset by a decrease in our California utility revenues of $0.5 million due to lower water consumption as a result of cooler temperatures and somewhat higher rainfall versus the prior year.

Services Group

Services Group revenues represent fees earned for water and wastewater facility operations and maintenance (O&M) services, equipment maintenance and repair, sewer pipeline cleaning, construction management services, state-certified water and wastewater laboratory analysis and public works. Revenues for the three months ended September 30, 2005 increased approximately $1.2 million, or 4%, to $31.4 million from $30.2 million during the same period of the prior year.

The increase in Services Group revenues was primarily due to the following:

1. A $1.9 million increase in revenue associated with contract operations, primarily those performed for our Utility Group, as well as increased project work. Of this increase approximately $0.5 million is billable work associated with Hurricane Katrina. See “Effects of Hurricanes Katrina and Rita” at beginning of Management Discussion and Analysis.

2. A $1.4 million increase due to the recent acquisition of contract operations in Alabama and a $0.2 million increase from revenues generated by a laboratory we acquired in the latter part of 2004.

3. These revenue increases were partially offset by a decrease of approximately $2.3 million in construction-related revenues for the reverse osmosis plant, which had been under construction since 2003 and was substantially completed as of September 30, 2005.

Expenses

Operating expenses – Utility Group

Operating expenses–Utility Group represent the costs of purchasing and producing water, treating wastewater, salaries, wages and employee benefits, facilities costs, power and electricity, supplies and equipment, repairs and maintenance, professional fees and other costs. Operating expenses for our Utility Group decreased $0.9 million, or 7%, to $12.8 million during the three months ended September 30, 2005, from $13.7 million during the comparable period of 2004. The decrease in operating expenses was primarily due to reduced operating expenses of $0.7 million at our California utility associated with lower water consumption as a result of cooler temperatures and somewhat higher rainfall versus the prior year. The lower consumption enabled us to reduce the amount of water purchased from outside sources, which is generally at prices higher than the cost of water pumped from our own wells.

Operating expenses–Utility Group, as a percentage of related revenues represented approximately 55% and 61% of revenues from utility operations for the three months ended September 30, 2005 and 2004, respectively. The decrease was primarily due to a decrease in operating expenses related to higher capitalized overhead, lower property taxes and repairs and maintenance in our California utility combined with increased revenues from the mid-July 2004 acquisition of Monarch Utility.

Operating expenses – Services Group

Operating expenses–services group include salaries, wages, employee benefits, project costs, fleet expenses, facilities costs, supplies and equipment, repairs and maintenance and professional fees. Operating expenses–services group increased approximately $1.0 million, or 4%, to $28.0 million during the three months ended September 30, 2005 from $27.0 million during the same period of 2004. The increase in operating expense–services group was due primarily to the following:

1. An increase in operating expenses of $1.1 million resulting from the recent acquisition of contract operations in Alabama and a $0.6 million increase generated by a laboratory we acquired in the latter part of 2004.

2. An increase of $0.9 million associated with contract operations, primarily those performed for our Utility Group, as well as increased project work.

3. An increase of $0.7 million of costs and expenses stemming from Hurricanes Katrina and Rita related to equipment losses, emergency supplies and temporary infrastructure relocation expenses. See “Effects of Hurricanes Katrina and Rita” at beginning of Management Discussion and Analysis.

4. These increases were partially offset by a decrease of approximately $2.3 million in construction work related to the reverse osmosis plant, which has been under construction since 2003 and was substantially completed as of September 30, 2005.

Operating expenses – Services Group, as a percentage of the revenues from the related operations remained constant at 89% for the three months ended September 30, 2005 compared to the same period of 2004.

Selling, general and administrative expenses

Selling, general and administrative expenses consist mainly of personnel, facilities, insurance and professional services costs, which support our sales, marketing, human resources, finance and administration functions. Selling, general and administrative expenses increased $0.8 million, or 12%, to $7.7 million for the three months ended September 30, 2005 compared to $6.9 million during the same period of 2004. Selling, general and administrative expenses increased to 14% of revenues for the three months ended September 30, 2005 from 13% for the three months ended September 30, 2004. The increase in selling, general and administrative expenses was primarily due to an increase of $0.6 million attributable to the acquisitions of Monarch Utility, contract operations in Alabama and laboratory service in Texas.

Other Income (Expense)

Interest Expense

Interest expense increased approximately $0.3 million, or 24%, during the three months ended September 30, 2005 compared to the same period in 2004. The major components of interest expense are as follows:

	For the Three Months Ended September 30,
	2005			2004
	(in thousands)
Interest expense - convertible subordinate debentures	$	289		$	327
Interest expense - bank lines of credit	496			322
Interest expense - mortgage bonds and bank term loan	906			889
Interest expense - other	387			85
Total interest expense before capitalized interest	2,078			1,623
Capitalized interest	(427		)	(177		)
Total interest expense	$	1,651		$	1,446

The increase in total interest expense is primarily due to an increase in our long-term debt and borrowing on our bank lines of credit resulting from acquisitions and capital spending. This was partially offset by increased capitalization of interest as a result of increased capital spending. Our average balances of interest-bearing debt outstanding were approximately $124 million and $114

Operating expenses – Services Group

Operating expenses–services group increased approximately $5.8 million, or 8%, to $80.6 million during the nine months ended September 30, 2005 from $74.8 million during the same period of 2004. The increase in operating expense–services group was due to the following:

1. An increase of operating expenses of approximately $3.6 million as a result of the recent acquisition of contract operations and a laboratory services in the latter part of 2004.

2. An increase of approximately $7.8 million associated with contract operations, primarily those performed for our Utility Group, as well as increased project work. The increased expense is also a result of increased staffing and fleet expense related to additional contract work, some of which was delayed from 2004. The staffing increase resulted in higher salary and wage expenses as well as benefits and other related costs.

3. An increase of approximately $0.7 million of costs and expenses stemming from Hurricanes Katrina and Rita related to equipment losses, emergency supplies and temporary infrastructure relocation expenses which we believe will not be reimbursable by FEMA. See “Effects of Hurricanes Katrina and Rita” at beginning of Management Discussion and Analysis.

4. These increases were partially offset by a decrease of approximately $6.3 million in construction work related to the reverse osmosis plant, which has been under construction since 2003 and was substantially completed as of September 30, 2005.

Operating expenses – Services Group, as a percentage of the related revenues, decreased to 88% for the nine months ended September 30, 2005, compared to 91% for the same period of 2004. The decrease was due to lower 2004 revenues as a result of higher rainfall relative to the expenses for additional construction, operating and maintenance work.

Selling, general and administrative expenses

Selling, general and administrative expenses increased $4.0 million, or 21%, to $23.0 million for the nine months ended September 30, 2005 compared to $19.0 million during the same period of 2004. Selling, general and administrative expenses increased to 15% of revenues for the nine months ended September 30, 2005 from 14% during the nine months ended September 30, 2004. The increase in selling, general and administrative expenses was primarily due to the following:

1. An increase in audit fees of $0.4 million, legal fees of $0.3 million, as well as an increase of $0.7 million in outside services, most of which is attributable to our efforts to prepare for and comply with the Sarbanes-Oxley Act of 2002 associated with our 2004 year end efforts.

2. An increase of $1.4 million primarily attributable to the Monarch acquisition which occurred in mid-July 2004.

3. A $1.2 million increase in costs compared to the prior period related to salaries and employee benefits as a result of increases in headcount to support our revenue trends.

Other Income (Expense)

Interest Expense

Interest expense increased approximately $1.9 million, or 56%, during the nine months ended September 30, 2005 compared to the same period in 2004. The major components of interest expense are as follows:

	For the Nine Months Ended
	September 30,

Capitalized interest	(509		)	(390		)
Total interest expense	$	5,251		$	3,371

The increase in total interest expense is primarily due to an increase in our long-term debt and borrowings on our bank lines of credit due to acquisitions and capital spending. This was offset in part by lower interest payments on our debentures as debenture holders

have converted these debt instruments into common stock and increased capitalization of interest as a result of our capital spending. Our average balances of interest bearing debt outstanding were approximately $128 million and $77 million for the nine months ended September 30, 2005 and 2004, respectively. In addition, our effective weighted average borrowing rate increased to 6.4% during the nine months ended September 30, 2005 from 6.1% during the nine months ended September 30, 2004.

Provision for Income Taxes

Our effective consolidated income tax rates on combined continuing and discontinued operations for the nine months ended September 30, 2005 and 2004 were approximately 35% and 37%, respectively.

During the nine months ended September 30, 2005 we recognized a capital loss of approximately $4.0 million for income tax purposes upon the sale of our submetering subsidiary. We will be able to carry back the capital loss to the prior three years and partially offset it against capital gains of approximately $0.9 million realized during those years. As a result, we recognized an income tax benefit of approximately $0.3 million during the second quarter of 2005, resulting in a net loss of approximately $3.7 million on sale of this subsidiary.

The remaining capital loss of approximately $3.1 million may be carried forward for a period of up to 15 years and offset against future capital gains, if any, which may be realized during those years. No income tax benefit has been recorded in 2005 for this capital loss carryforward.

Liquidity and Capital Resources

Our corporate objectives with respect to liquidity and capital resources are to: (i) generate sufficient operating cash to provide for dividends, principal and interest requirements on our indebtedness, capital improvements, and taxes; (ii) obtain external financing for long-term capital improvements and acquisitions; (iii) use our credit facilities to manage seasonal cash needs; and (iv) maintain approximately equal levels of debt and equity.

Our statements of cash flows are summarized as follows:

	2005			2004
	(in thousands)
Net cash provided by continuing operating activities	$	17,946		$	726

Net cash provided by financing activities	14,279			66,449
Net increase in cash and cash equivalents	$	5,363		$	1,087

Cash Flows From Continuing Operating Activities

Cash and cash equivalents increased by approximately $5.4 million for the nine months ended September 30, 2005, as compared to $1.1 million in 2004. The increase in 2005 cash and cash equivalents was due to strong cash flow from our operating activities which was significantly higher than last year due to:

• acquisitions,

• increased customer connections,

• increased client contracts, and

• increased revenues on our existing contract operations.

For further discussion on operating revenues and expenses see Results of Operations.

Cash Flows from Investing Activities

Our investing activities focus on capital spending related to expansion, replacement and renovation of our water and wastewater systems of approximately $26.0 million with significant spending occurring in our Texas and California utilities versus prior year spending of $16.0 million.

Contributions in Aid of Construction (“CIAC”) represent contributions in the form of cash, services or property received from developers, governmental agencies, municipalities or individuals for the purpose of constructing utility plant. Our capital spending on our water and wastewater systems has benefited from contributions from developers to aid in construction of these facilities of approximately $2.8 million as compared to approximately $2.6 million from the same period last year.

The following table summarizes property, plant and equipment additions for each of the first nine months in 2005 and 2004.

Total additions to property, plant and equipment	$	28,303	$	21,357

Cash payments for acquisitions during the first nine months of 2005 and 2004 included:

• $2.6 million in 2005 in cash for the purchase of Alabama contract operations,

• $8.5 million in 2005 in cash for the purchase of an Alabama utility company,

• $2.9 million in 2004 to acquire the remaining minority interest in our submetering subsidiary which was sold in June 2005, and

• $46.7 million in 2004 to acquire Monarch, one of our Texas utilities.

Cash Flows from the Sale of Discontinued Operations

The increase of approximately $9.8 million in net proceeds from sale of our submetering subsidiary improved our cash position. In June 2005, we completed the sale of our submetering subsidiary in our services segment for approximately $12.0 million. We received approximately $10.8 million in cash and approximately $1.2 million of the sales price was placed into an escrow account. We incurred transaction costs of approximately $1.0 million to complete the sale and our net proceeds on the sale of submetering subsidiary were approximately $9.8 million. The cash from the sale was subsequently used to pay down our bank lines of credit in our New Credit Facility.

Cash Flows from Financing Activities

Our financing activities involved the following significnat events during the first nine months of 2005 as follows:

• Net borrowings on our revolving lines of credit in 2005 of approximately $4.0 million.

• Our net cash provided by financing activities increased through additional borrowings of long term debt of $20.0 million. This was partially offset by repayments on our long term debt of approximately $16.4 million.

• Sales of stock of approximately $4.5 million.

Our financing activities involved the following significant events during the first nine months of 2004 as follows:

• Net borrowings on our revolving lines of credit of approximately $25.7 million.

• A public offering of approximately 1.6 million shares of our common stock in March 2004, which generated net proceeds of approximately $20.5 million.

• A public offering of approximately 1.8 million shares of our common stock in August 2004, which generated net proceeds of approximately $20.7 million.

Common stockholders may elect to participate in our Amended and Restated Dividend Reinvestment and Stock Purchase Plan (“DSPP”), which gives them the option of receiving their dividends in either cash or common stock at a 5% discount from current market value. This plan also permits optional cash purchases of stock at current market values of up to $10,000 per stockholder each month. Our cash position benefited by approximately $7.6 million as we experienced significant activity in direct stock purchase activity of approximately $4.5 million and primarily stock option exercises which contributed approximately $3.1 million.

During 2005, we paid dividends totaling approximately $3.0 million. Our quarterly dividend rate is currently $0.05 per common share.

Aggregate borrowings under our revolving lines of credit were approximately $27.0 million as of September 30, 2005, an increase of approximately $4.0 million since December 31, 2004, primarily used for capital expenditures. Our total borrowing availability under the New Credit Facility was approximately $69.1 million as of September 30, 2005.

We entered into a new 5-year credit facility with a syndicate of banks in April 2005, which provides for a $100 million revolving credit facility. In April 2005, we used a portion of our borrowings from the New Credit Facility to repay amounts outstanding, and to extinguish, our lines of credit and certain other indebtedness.

As part of implementing the New Credit Facility the following actions were taken to reduce interest expense:

1) Redeemed $4.0 million of our New Mexico bonds on April 4, 2005,

2) Redeemed notes payable of approximately $2.5 million on April 29, 2005,

3) Repayment of a term loan for one of our Texas utilities in the amount of approximately $8.8 million on April 1, 2005, and

4) Repaid a revolving credit facility for our New Mexico Utility in the amount of approximately $3.8 million on April 1, 2005.

Our capital resources are used for debt service on our bonds and debentures and are also influenced by investments we make in new business ventures, including the acquisition of companies and contract operations. We have historically generated reasonably stable operating cash flows.

We expect to spend approximately $9.0 million for cash capital expenditures for the remainder of 2005, primarily for utility property, plant and equipment. We plan to fund those expenditures with cash flow from operations, borrowings under our New Credit Facility, long term debt financing and other sources.

At September 30, 2005, we had working capital of approximately $11.8 million including available cash and cash-equivalent balances of approximately $6.8 million (excluding restricted cash balances).

We have an effective registration statement on file with the Securities and Exchange Commission (“SEC”). Approximately $6 million remains available for issuance of securities as of September 30, 2005 under this registration statement. We may offer these securities for sale at any time and from time to time.

Off-Balance Sheet Arrangements

We do not have any material off-balance sheet arrangements other than leases that have been classified as operating leases in accordance with accounting principles generally accepted in the United States (“US GAAP”).

Debt Obligations

Following is a summary of our debt obligations and commitments due in the remaining three months of 2005 and in the specified periods thereafter. Amounts represent the expected cash principal payments related to our long-term debt.

(1) Represents principal payments to be made the remainder of the year.

We have $8.0 million of 7.61% first mortgage bonds maturing on October 20, 2006. We are exploring various alternatives with respect to funding this redemption obligation including refinancing the obligation through the sale of new mortgage bonds or funding the obligation with borrowings under the New Credit Facility.

In April 2005, we entered into the New Credit Facility. The New Credit Facility provides for a $100 million revolving credit facility, which includes a $40 million letter of credit subfacility and a $10 million swingline subfacility. The New Credit Facility contains customary covenants, as well as customary events of default. Certain of our subsidiaries have guaranteed our obligation to repay borrowings under the New Credit Facility.

Loans under the New Credit Facility (other than swingline loans) bear interest at a rate equal to (i) LIBOR plus the applicable margin (as provided for in the New Credit Facility), or (ii) a base rate (as defined) minus the applicable margin. At September 30, 2005, we had $27.0 million of outstanding borrowings under our New Credit Facility and the adjusted average borrowing rate was approximately 4.8%. The New Credit Facility replaced our existing lines of credit which had provided for up to $50.0 million of borrowings and we used the New Credit Facility to repay amounts outstanding under those lines of credit. As of September 30, 2005, we were in compliance with all applicable covenants under our outstanding line of credit agreements.

In January 2003, we received a $3.4 million line of credit from one of our commercial banks that we used to issue a standby letter of credit in that amount as collateral for performance under a contract to design and construct the CVWD plant. On April 1, 2005, the standby letter of credit was transferred to the New Credit Facility and the standby line of credit was cancelled.

In addition to the foregoing, the indentures governing the first mortgage bonds for our California and New Mexico utilities allow for the issuance of approximately $65.0 million of first mortgage bonds at these utilities as of September 30, 2005.

We anticipate that our available credit facility borrowing capacity, cash flows generated from operations, long-term debt financing and other sources will be sufficient to fund our activities during the next 12 months; however, we cannot guarantee that will be the case. If we needed additional financing and were unable to obtain it, our capital spending and any future acquisitions would be delayed, reduced, or eliminated.

Critical Accounting Policies

Our consolidated financial statements are prepared in accordance with US GAAP. These accounting principles require us to make certain estimates, judgments and assumptions. We believe that the estimates, judgments and assumptions are reasonable based upon information available to us at the time that these estimates, judgments and assumptions are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities as of the date of the financial statements, as well as the reported amounts of revenues and expenses during the periods presented. To the extent there are material differences between these estimates, judgments or assumptions and actual results, our financial statements will be affected. The significant accounting policies that we believe are important to fully understanding and evaluating our reported financial results include the following:

• Revenue recognition,

• Valuation of long-lived and intangible assets,

• Accounting for regulated businesses,

• Stock-based compensation, and

• Deferred costs.

Our senior management has reviewed these critical accounting policies and related disclosures with the audit committee of the Board of Directors.

Revenue recognition

Water utility revenues are recognized when water is delivered to customers. At the end of an accounting period, estimated amounts for unbilled revenues are accrued for water usage since the previous billing period.

Revenues for contract operations are recognized and billed at the end of the month based on a monthly fee to provide a specific level of service as outlined in each individual contract. We generally bill for additional services provided beyond the scope of the base contract on a time-and-materials basis as such services are rendered.

Revenues for construction projects are recorded using the percentage-of-completion method of accounting. The percentage-of-completion method recognizes revenue and income as work progresses on a project based on the expected total project costs and the expected total project revenues. This method is based on an estimate of the revenue and income earned to date, less the revenue and income recognized in earlier periods. If management anticipates we will ultimately suffer a loss on a construction project, the entire estimated loss is recorded in the period such a determination is made.

If a contract involves the provision of a single product or service, revenue is generally recognized when the product or service is provided and the amount becomes billable. If services are provided evenly during the contract term but service billings are irregular, revenue is recognized on a straight-line basis over the contract term.

Certain non-refundable activation fees in our non-regulated wholesale water operations are accounted for on a completed contract basis and subsequently deferred and recognized over the expected period of performance.

If a contract involves the provision of multiple products or services (elements), total estimated contract revenue is allocated to each element based on the relative fair value of each service, provided the services qualify for separation under Emerging Issues Task Force (“EITF”) 00-21, Accounting for Revenue Arrangements with Multiple Deliverables. The amount of revenue allocated to each service is limited to the amount that is not contingent upon the delivery of another element in the future. Revenue is then recognized for each element as described above for single-element contracts, except revenue recognized on a straight-line basis for a non-construction service will not exceed amounts currently billable unless the excess revenue is recoverable from the client upon any contract termination event. If the amount of revenue allocated to a construction service is less than its relative fair value, costs to deliver such service, limited to the difference between allocated revenue and the relative fair value, are deferred and amortized over the contract term. If total construction service costs are estimated to exceed the relative fair value for the construction service contained in a multiple-element arrangement, then a provision for the estimated loss is made in the period in which the loss first becomes apparent.

Valuation of long-lived and intangible assets

In accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, we assess intangible assets and other long-lived assets, excluding goodwill, for recoverability whenever events or changes in circumstances indicate that their carrying value may not be recoverable through the estimated undiscounted future cash flows resulting from the use of the assets. If we determine that the carrying value of intangible assets or other long-lived assets may not be recoverable, we measure impairment by using the projected discounted cash-flow method in accordance with Statement No. 144.

We have made acquisitions in the past that resulted in recording goodwill and intangible assets. In September 2001, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 142, Goodwill and Other Intangible Assets. SFAS No. 142 requires that goodwill and intangible assets with indefinite useful lives are not amortized, but instead are tested for impairment at least annually. For intangible assets with finite useful lives, SFAS No. 142 requires amortization over their estimated useful lives. SFAS No. 142 became effective for fiscal years beginning after December 15, 2001. We evaluate goodwill impairment, at least annually, using discounted cash flow methodologies, transaction values for comparable companies, and other valuation techniques for our reporting units with significant goodwill balances. Our reporting units, generally subsidiaries one level below operating segments, constitute separate businesses for which we maintain discrete financial information that is regularly reviewed by segment and chief operating decision maker. There were no impairment charges to goodwill as of September 30, 2005 and no events have occurred that indicated diminution in the value of recorded goodwill.

Under the provisions of SFAS No. 141, Business Combinations, we have identified intangible assets apart from goodwill such as contract costs and account lists. These intangible assets are amortized over their estimated useful lives ranging from four to eight years.

Accounting for regulated businesses

Our regulated businesses, which include our utilities in Alabama, California, New Mexico, Oklahoma and Texas, are required to be accounted for under the provisions of SFAS No. 71, Accounting for the Effects of Certain Types of Regulation, which specifies certain revenue, expense and balance sheet treatment as required by each state’s regulatory authority. Each state authority establishes rates which are intended to permit each utility to recover its costs and earn a reasonable rate of return.

Our Services Group has contracted with our utilities in Alabama, Oklahoma, New Mexico and Texas to perform operating services, maintenance, construction work, and to manage capital projects. In accordance with SFAS No. 71, our Services Group recognizes profit on sales to regulated affiliates and does not eliminate the intercompany profit when the sales price is reasonable and it is probable that, through the rate making process, future revenue approximately equal to the sales price will result from the regulated affiliate’s use of the services. However, all revenue in excess of profits is eliminated. Accordingly, the intercompany profit for construction as well as operations and maintenance services provided to Utility Group affiliates has not been eliminated in the accompanying consolidated financial statements. Based upon our Services Group’s experience of providing operations and maintenance services in more than 400 contracts with unaffiliated customers, and a history of regulator approval of the construction service fees charged by the Services Group to utility affiliates, we believe that the contract sales prices between our Services Group and our Texas and New Mexico utilities are reasonable and that it is probable that the price of these services will be recovered in the rate-making process.

Stock-based Compensation

In 2002, we adopted the fair value recognition provisions of SFAS No. 123, Accounting for Stock-Based Compensation, which requires valuation of stock options issued based upon an option pricing model and recognition of this value as an expense over the period in which the options vest. In accordance with the provisions of SFAS No. 148, we elected to recognize stock-based compensation using the retroactive restatement method. Under this change in accounting method, we restated our accompanying consolidated financial statements for periods prior to 2002 to reflect stock-based compensation expense under a fair value based accounting method for all options granted, modified or settled in fiscal years beginning after December 15, 1994.

We use the Black-Scholes option valuation model to estimate the fair value of our stock options. This option valuation model was developed for use in estimating the fair value of traded options that do not have vesting restrictions and that are fully transferable. Option valuation models require subjective assumptions such as the expected future volatility of the stock price. Because the stock options we grant have characteristics that are significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the calculated results, in management’s opinion, the stock option valuation models, including Black-Scholes, may not necessarily provide an exact measure of the fair value of employee stock options.

Deferred Costs

We defer and subsequently amortize certain direct contract acquisition costs related to activities that enable the provision of contracted services to our customers. Deferred contract acquisition costs are amortized on a straight-line basis over the remaining original contract term unless revenue patterns indicate a more accelerated method is appropriate. The recoverability of all long-lived assets associated with a particular contract, including deferred contract costs, is analyzed on a periodic basis. If we conclude that long-lived assets are impaired, an impairment loss is recognized for the amount by which the carrying value of the long-lived assets exceeds the fair value of those assets.

RISK FACTORS

The following factors, which are described more fully in our 2004 Annual Report, represent risks and uncertainties that could cause actual results to differ materially from our historical experience and our present expectations or projections. Factors that could affect forward-looking statements relating to the resolution of the material weakness with respect to internal controls discussed in Item 4 below and Item 9A of our 2004 Annual Report, include among other things: our ability to identify and retain qualified and experienced financial personnel and our ability to design and maintain policies and procedures which enable us to avoid any recurrence of the matters which gave rise to the material weakness. See “Risk Factors” in our 2004 Annual Report for further disclosure related to risk factors.

Risks Related to Our Business

Risk Factors that affect our Utility Group operations

• Weather conditions can affect the financial results of our Utility Group.

• We may issue additional shares of our common stock.

Other Risk Factors

• Our capital resources may restrict our ability to operate and expand our business.

• If we continue to grow, we may fail to effectively manage our growth or we may fail to effectively manage the growth we have experienced.

• Our business may be affected by the general economic conditions of real estate development in the United States.

• We are subject to debt covenants.

• Rating agencies may downgrade our debt.

• We are subject to increasing costs of producing products and services.

• Our operations are subject to certain risks due to their locations.

• Internal control weaknesses could have an adverse effect on us. We may not be able to remediate the material weakness noted in the 2004 Annual Report in a timely manner.

• The United States Environmental Protection Agency closely regulates many of our businesses and we must comply with its rules and regulations.

• We rely on a number of complex business systems that could malfunction.

• We retain certain risks not covered by our insurance policies.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

There are no material changes from our 2004 Annual Report.

Item 4. Controls and Procedures

We maintain disclosure controls and procedures designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified by the Securities and Exchange Commission and that such information is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As discussed in our 2004 Annual Report, filed with the SEC on March 31, 2005, accounting errors were identified during the fourth quarter of 2004 that were caused by lack of an effective review by appropriate accounting personnel of the accounting for certain non-routine transactions. The transactions involved a) purchase accounting for an acquisition, b) balance sheet classification of long-term debt, and c) accounting for a gain contingency. As a result of this internal control deficiency, there was more than a remote likelihood that the Company’s interim or annual financial statements could have been materially misstated, and accordingly, such deficiency was considered a material weakness in internal control over financial reporting as of December 31, 2004. A material weakness is a control deficiency, or combination of control deficiencies, that results in more than a remote likelihood that a material misstatement of the annual or interim financial statements would not be prevented or detected. Because of the material weakness described above, management concluded that, as of December 31, 2004, our internal control over financial reporting was not effective.

We are in the process of implementing improvements to our internal controls to address the aforementioned material weakness. We have implemented procedures in our accounting review and approval process over non-routine transactions. These include implementation of additional checklists, more timely review and accounting for non-routine transactions and timely identification of non-routine issues with our auditors. We have evaluated appropriate staffing and experience levels in our corporate controllership function and have hired the additional experienced personnel we feel appropriate. In addition, during the second and third quarters of 2005, we have made significant progress in preparation for complying with the Sarbanes-Oxley Act for the year end 2005.
