Analytical Surveys, Inc. (“ASI”, “we”, “our” or the “Company”), formed in 1981, provides customized data conversion, spatial data management and technical services for the geographic information systems market. Geographic information systems (“GIS”) are used by federal, state and local governments, utilities and other businesses to store, update, analyze and display information about the physical location and characteristics of their diverse assets. We help customers by transforming or updating raw, often confusing information from multiple sources (maps, blueprints, construction drawings, databases, aerial photography, satellite imagery, etc.) into a high-resolution, large-scale, richly detailed digital and visual representation on which organizations can rely to make better decisions with speed and confidence. We have historically targeted our services to utilities and state and local governments, and are implementing strategies to expand the range of GIS-related spatial data management and technical services offered to these markets.

We believe that the market for GIS systems and GIS-related services has grown due to growing awareness of the benefits of GIS technology coupled with lower hardware prices and increased software capability. Our customers today use GIS technology to:

We believe that GIS outsourcing is a growing tendency that enables our customers to focus on their core competencies. This trend provides us with the opportunity to leverage our GIS expertise into longer-term program contracts to maintain existing GIS systems in addition to our traditional contracts to build new GIS systems. Many utilities invested in GIS technology in the late 1990s resulting in improvements in operations and customer service levels. Our belief is that while many of these same companies desire new levels of improvement and maintenance of quality information, they are challenged to do so because of the cost of training and retaining highly specialized GIS technicians. We are GIS specialists and we believe that we are well positioned to provide such specialized services to these companies.

Our ongoing involvement with the technology leaders such as Intergraph and ESRI, has kept our employees abreast of the latest GIS technology. We think that by entering into long-term outsourcing contracts with us, our clients can spare the expense and risk of developing an internal resource capability necessary to provide them with higher cost savings through an efficient implementation of the latest GIS technologies.

Global economic conditions have slowed the rate of growth in the GIS market since 2000. We expect delays in growth consistent with other technology-related companies until our utility customers resume significant spending on information technology products and services. Newer competition, primarily from service firms with a large labor content in India, has resulted in lower margins and increased competition in the industry. The technologies utilized by our GIS customer base continue to advance and demand a current and accurate depiction of their spatially located assets. We believe, therefore, that the long-term outlook for the GIS industry is positive and that we are well positioned to serve evolving customer needs.

We enter into long-term, fixed price contracts. Payments for these contracts are often spread throughout the term of the contract and may be based on successful interim data deliveries or milestone payments. We attempt to negotiate new contracts to minimize negative cash flow and be self-funding throughout the life of the contract.

On January 28, 2004, we announced that our Chief Executive Officer, J. Norman Rokosh, voluntarily resigned for personal and family reasons as our President and Chief Executive Officer, effective February 29, 2004, and as a member of our Board of Directors, effective January 28, 2004. Mr. Rokosh has continued to work with us to ensure a smooth transition to new leadership.Mr. J. Livingston Kosberg, our current Chairman of the Board, served as our interim Chief Executive Officer until March 22, 2004, when Mr. Wayne Fuquay was appointed as Chief Executive Officer.

Effective January 28, 2004, Joshua Huffard resigned as a member of our Board of Directors and as member of our Audit Committee. Mr. Huffard’s resignation was not related to a disagreement with our operations, policies, or practices.

On April 12, 2004, Mr. Hamid Akhavan replaced Mr. Tom Bannon as Senior Vice President of Operations. Mr. Akhavan was previously employed by us and held various senior level positions in both operations and sales from 1984 until January 2004. He has provided consulting services to us since January.

Certain statements included in this prospectus and in the documents that we have incorporated by reference that are not historical facts are intended to be “forward-looking statements.” Such forward-looking statements may include statements that relate to:

Forward-looking statements generally can be identified by the use of words such as “may,” “will,” “expect,” “intend,” “estimate,” “anticipate” or “believe” or similar language.

Forward-looking statements are not guarantees of future performance and all phases of our operations are subject to a number of uncertainties, risks and other influences, many of which are beyond our control. Any one of such influences, or a combination, could materially affect the results of our operations and the accuracy of the forward-looking statements that we make. Some important factors that could cause actual results to differ materially from the anticipated results or other expectations expressed in our forward-looking statements are discussed under the caption “Risk Factors” beginning on page 5. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date that they are made. We undertake no obligation to publicly update our forward-looking statements.

You should carefully consider the following risk factors, in addition to the other information set forth or incorporated by reference in this prospectus, before purchasing shares of our common stock. Each of these risk factors could adversely affect our business, operating results and financial condition, and also adversely affect the value of an investment in our common stock.

Our cash flow may be insufficient to meet our operating and capital requirements.

We currently do not have a line of credit with any lender and rely solely on cash flow from operations to fund future operations and expenditures. There is no assurance that the cash flow from operations will be sufficient to meet our capital requirements. The terms of our $1.7 million aggregate principal amount senior secured convertible promissory note (the “Note”) restricts our ability to secure additional debt and also contains certain immediate call provisions that are outside our control, which if triggered and exercised, would accelerate the Note and change the terms from being solely convertible to common stock at maturity to being immediately payable in cash. At March 31, 2004, the value of the unconverted portion of the Note plus accrued interest totaled $1,870,000. If a default provision was triggered and Tonga Partners, L.P. (“Tonga”), the holder of the Note, did not waive such default but demanded repayment of the Note plus accrued interest in cash, it would be difficult for us to meet this and other debt payments as well as fund our operations. If we do not have the cash flow necessary to meet our operating and capital requirements, we will be in violation of the agreement with Tonga and we would be forced to obtain additional financing with Tonga’s consent and/or restrict capital and operating expenditures to match available resources. If these actions are not sufficient, and we are not able to meet our commitments when due, then we will be forced to liquidate assets and repay our secured creditors with the proceeds.

Our independent auditors have expressed that there is substantial doubt about our ability to continue as a going concern.

During fiscal years 2000 through 2003, we experienced significant operating losses with corresponding reductions in working capital and net worth, excluding the impact of debt forgiveness. Our revenues and backlog have also decreased substantially during the same period. Our independent auditors issued a going concern qualification on our financial statements for each fiscal year since the fiscal 2000 results were reported. The going-concern qualification, which expressed substantial doubt about our ability to continue as a going concern, was based on the significant operating losses reported in fiscal 2003 and 2002 and a lack of external financing to fund working capital and debt requirements. As of December 31, 2003, the amount of our accumulated deficit is approximately $30 million.

Successful implementation of our turnaround efforts is required to return the Company to profitability.

The successful implementation of our turnaround efforts requires the cooperation of customers, subcontractors, vendors, lenders, outside professionals and employees. There can be no assurance that the specific strategies designed to return our operations to profitability and positive cash flow can be implemented to the extent and in the timeframe planned. We have implemented financial and operational restructuring plans designed to improve operating efficiencies, reduce and eliminate cash losses and position ourselves for profitable operations. Delays and difficulties in achieving sales targets, realizing cost savings, retaining employees and other turnaround efforts could have a material adverse effect on our operations.

The market for our services is highly competitive and such competition within our industry can lead to lower profit margins and reduced volume of new work.

As the GIS services industry evolves, additional competitors may enter the industry. In addition, other improvements in technology could provide competitors or customers with tools to perform the services we provide and lower the cost of entry into the GIS services industry. We are facing increased price competition, particularly in the utilities market, from relatively new entrants to the market, which perform their work utilizing mostly offshore labor. A number of our competitors or potential competitors may have capabilities and resources greater than ours.

Our customer contracts may be adversely modified, changed or terminated prior to the expiration of the contract terms.

Most of our revenue is earned under long-term, fixed-price contracts. Our contractual obligations typically include large projects that will extend over six months to four years. These long-term contracts entail significant risks, including:

We experience quarterly variations in our operating results due to external influences beyond our control.

Our quarterly operating results vary significantly from quarter to quarter, depending upon factors such as the following:

We also could experience reduced revenues as a result of general weak economic conditions as customers defer projects or cancel planned expenditures.

We have devoted significant resources to developing and acquiring specialized data collection and conversion hardware and software. In order to remain competitive, we must continue to select, invest in, acquire and develop new and enhanced technology on a timely basis. There can be no assurance that we will be successful in these efforts or in anticipating developments in data conversion technology.

We do not have any patent protection for our products or technology. Third parties could independently develop technology similar to ours, obtain unauthorized access to our proprietary technology or misappropriate technology to which we have granted access.

Our business comes from two core markets and adverse changes in those markets could cause a reduction in the demand for our services.

We derive our revenues primarily from two core markets, utilities and state and local governments. The ongoing consolidation and reduced technology budgets of the utilities industry has and may continue to increase competition and reduce profitability for the GIS services projects of current and potential customers. Also, to the extent that utilities remain regulated, legal, financial and political considerations may constrain the ability of utilities to fund geographic information systems. Many state and municipal entities are subject to legal constraints on spending, and a multi-year contract with any such entity may be subject to termination in any subsequent year if the entity does not choose to appropriate funds for such contracts in that year. Moreover, fundamental changes in the business practices or capital spending policies of any of these customers, whether due to budgetary, regulatory, technological or other developments or changes in the general economic conditions in the industries in which they operate, could cause a material reduction in demand by such customers for the services we offer. Any such reduction in demand could have a material adverse effect on our operations.

The unavailability of a skilled labor force may hinder our ability to produce accurate, cost-effective solutions to meet the terms of our contracts.

Our business is labor-intensive and requires trained employees. We compete for qualified personnel against numerous companies, including more established companies with significantly greater financial resources than ours. Our business, financial condition and results of operations could be materially adversely affected if we are unable to hire qualified personnel or if we are unable to retain qualified personnel in the future. High turnover among our employees could increase our recruiting and training costs, could affect our ability to perform services and earn revenues on a timely basis and could decrease operating efficiencies and productivity. In addition, a significant portion of our costs consists of wages to hourly workers. An increase in hourly wages, costs of employee benefits or employment taxes could have a material adverse effect on us.

If we are unable to retain the members of our senior management team our business operations may be adversely impacted.

Our success depends upon the continued service of our key employees: Wayne Fuquay, Chief Executive Officer; Lori Jones, Chief Financial Officer; John Federowicz, Vice President—Sales and Data Management Solutions; and Hamid Akhavan, Senior Vice President—Operations. Our ability to retain our management team is an important factor in our turnaround program and our ability to pursue our overall business plan. While we have employment agreements with Ms. Jones and Messrs. Fuquay and Federowicz, there is no assurance that we will be able to retain the services of such key personnel. We do not maintain any key personal life insurance policies. Layoffs in recent years may impair our ability to retain and recruit other key personnel. The loss or interruption of the services of Ms. Jones or of Messrs. Fuquay, Federowicz or Akhavan could have a material adverse effect on our

business, financial condition and results of operations. Our future financial results will also depend upon our ability to attract and retain highly skilled technical, managerial and marketing personnel.

The unavailability or unsatisfactory performance of our subcontractors may affect our ability to deliver quality services to our customers.

Certain of our services require us to perform tasks that are outside our expertise such as the acquisition of aerial photography. We are dependent upon the continued availability of third party subcontractors for such production tasks. We also use subcontractors for work similar to that performed by our own employees such as field data acquisition. The use of subcontractors allows us to manage the fluctuations in labor requirements in various phases of our contracts, expand capacity, meet deadlines, and reduce production costs. The insufficient availability of or unsatisfactory performance by these unaffiliated third-party subcontractors could have a material adverse effect on our business, financial condition and results of operations due to delays in project schedules, product quality and increased costs of production.

The unsatisfactory performance or unavailability of overseas subcontractors may impact our ability to profitably perform services under existing contracts.

We utilize subcontractors in India and may from time to time use subcontractors in other overseas locations to perform certain tasks such as data conversion and photogrammetric interpretation at lower costs than could be achieved in the United States. Our ability to perform services under some existing contracts on a profitable basis is dependent upon the continued availability of our overseas subcontractors and the quality of their work. For example, India has in the past experienced significant inflation, civil unrest and regional conflicts. Events or governmental actions that would impede or prohibit the operations of our subcontractors could have a material adverse effect on us. We are in the fifth year of a five-year exclusive agreement with InfoTech Enterprises, Ltd., an India-based company, to provide production capacity for data conversion and other related services. Under the agreement, we had provided certain assurances of production volume to InfoTech. Currently, we are not meeting these production volume commitments due to the weakened demand for services from our customer base. In consideration for this volume shortfall, we have permitted InfoTech to seek additional work volume in the aerial photogrammetry sector. In addition, to supplement its work volume InfoTech has sought other work directly from our competitors based in the United States. If our exclusive agreement with InfoTech is not renewed, we may have to secure an alternate source of labor in India. This may increase our cost of offshore services in the short term as we train a new supplier, and may cause delays in completing existing contracts. We utilize InfoTech to provide more than 90% of our offshore subcontractor services (which services constitute less than 10% of our total production costs).

We receive some business from referrals and any reduction in those referrals could affect our business.

A portion of our sales is the result of referrals derived, either directly or indirectly, from engineers, software developers and consultants in the GIS industry. We believe that our continued success in the GIS services market is dependent, in part, on our ability to maintain current relationships and to cultivate additional relationships with other industry participants. Such participants could acquire a GIS data collection or data conversion business or businesses or form other relationships with our competitors. There can be no assurance that relationships with GIS consultants will continue to be a source of business for us. Our inability to maintain such relationships or to form new relationships could have a material adverse effect on our operations.

We have outstanding preferred stock and “blank check” preferred stock that could be issued resulting in the dilution of share ownership.

Our Articles of Incorporation allow the board of directors to issue up to 2,500,000 shares of preferred stock and to fix the rights, privileges and preferences of those shares without any further vote or action by the shareholders. Our outstanding preferred stock holds dividend priority and liquidation preferences over shares of our common stock, including the common stock being registered in this Registration Statement. However, because the outstanding preferred stock is not convertible to common stock, it has no potential dilutive effect on the shares offered under this Registration Statement. Nonetheless, the common stock will be subject to dilution if our board of directors utilizes its right to issue additional shares of preferred stock that is convertible into common stock. The rights of the holders of common stock are and will be subject to, and may be adversely affected by, the rights of the

holders of the 1.6 million shares of preferred stock that we have previously issued and any preferred stock that we may issue in the future. Any such issuance could be used to discourage an unsolicited acquisition proposal by a third party.

We are effectively controlled by a single stockholder which may result in biased decision-making.

Tonga currently owns 261,458 shares, or 24.1%, of our outstanding common stock. Tonga also holds the Note and warrants to purchase 500,000 shares of our common stock.

The Note plus accrued interest is convertible at any time into common stock at a price that varies in accordance with the changes in the closing bid price of our common stock. A lower closing bid price will effect a lower Conversion Price and a higher percentage of ownership by Tonga upon conversion. The Note includes a provision that Tonga will own a minimum of 38% or 55% of our common stock upon full conversion of the Note or upon full conversion and exercise of the warrants, respectively (unless Tonga exercises the warrants in a cashless exercise where Tonga uses the value of some of the warrants to pay the exercise price for other warrants). Prior to the effectiveness of this registration statement, Tonga has the right to exercise the warrants through a cashless exercise mechanism. If the $1,700,000 Note had been converted in full on April 1, 2004, the conversion price would have been $2.38, and we would have issued 786,607 shares to redeem the principal and accrued interest. The conversion price would have been equal to 90% of the average closing bid prices of the common stock for the three trading days having the lowest closing bid price during the 20 trading days preceding April 1, 2004. If the warrants had been exercised April 1, 2004 pursuant to an effective registration statement, the exercise price would have been $2.74 (115% of $2.38), and the proceeds from the exercise of all the warrants and issuance of 500,000 shares of common stock would have been $1,370,000. Tonga would have owned 65% of our outstanding shares immediately after the conversion and exercise of warrants.

Pursuant to the Note and the purchase agreement executed in April 2002, Tonga has the right to appoint a majority of our board of directors. Accordingly, Tonga has the power to effectively control the election of our directors and to influence the outcome of various corporate actions requiring shareholder approval. All three outside members of our current board of directors are Tonga appointees.

Our stock price is highly volatile and the purchase or sale of relatively few shares can disproportionately influence the share price.

The trading price and volume of the common stock has been and may continue to be subject to significant fluctuations in response to:

The trading price of the common stock may vary without regard to our operating performance. Historically, we have been a thinly traded stock, therefore relatively few shares traded can disproportionately influence share price.

We have restated our consolidated financial statements for the quarter ended December 31, 2003, and the years ended September 30, 2003 and 2002, and while the adjustments are non-operational in nature and include non-cash interest charges and non-cash other income or expense and the weighted average of diluted shares outstanding, the market may look unfavorably on such restatement.

The restatement was made to reflect the proper accounting for the conversion feature of the Note and the related warrants that were issued on April 2, 2002. The application of these features as derivatives results in two non-operational items: non-cash interest charges and other income or expense resulting from the change in fair value of the derivative features. The carrying value of the Note has been adjusted to record the discount created by the original $336,000 fair market value of the derivative features and the accretion of interest resulting from the discount. The warrants were reclassified to current liabilities, which resulted in a $200,000 decrease to common stock. Both the warrants and the conversion feature (“derivative instruments”) are reported as current liabilities and have been recognized at fair value as of December 31, 2003, and September 30, 2003 and 2002. The decrease in these liabilities from the date of issuance to September 30, 2002, resulted in an increase to other income totaling $90,000, partially offset by $23,000 accretion of the related indebtedness. Additionally, the computations for the weighted average of diluted shares outstanding for the year ended September 30, 2002, were not properly calculated in our fiscal 2003 disclosures. Diluted earnings per share have been restated to reflect the correct weighted average shares outstanding. The net result of these adjustments for the year ended September 30, 2002, increased the net income available to common shareholders and reduced the accumulated deficit by $67,000, and basic and diluted earnings per share available to common shareholders increased by $0.10 and $1.71, respectively.

The derivative instruments have been recognized at fair value as of September 30, 2003, resulting in a $39,000 increase to other income in fiscal 2003, and we recorded $45,000 of additional interest expense resulting from the amortization of the discount to the Note. The net result of these fiscal 2003 adjustments increased the net loss available to common shareholders and the accumulated deficit by $6,000 and net loss per share available to common shareholders increased by $0.01.

Similar adjustments in the quarter ended December 31, 2003, resulted in an additional $12,000 interest expense and $53,000 other expense. The net loss available to common shareholders for the first quarter of fiscal 2004 increased by $65,000 and net loss per share available to common shareholders increased by $0.07.

The original carrying value of the Note ($1.664 million) which is the $2 million face value less the fair value of the derivatives, will be accreted to the face value as we record interest expense during the three year term of the Note at a rate of $28,000 per fiscal quarter. The $336,000 liability will be decreased over the three-year term of the Note and will be adjusted to reflect the increase or decrease in fair value of the derivatives at the end of each fiscal quarter. The liability will be reduced to $0 upon maturity or other disposition of the Note, and we will recognize net other income totaling $336,000 during the term of the Note, but not in accordance with the rate at which we record interest expense. The adjustments will result in other income or expense and will fluctuate in accordance with the changes in the fair value of our common stock.

All of the shares of common stock offered hereby are being offered by the selling shareholders, who will receive all proceeds from such sales. We will not receive any proceeds from the sale of shares of common stock offered by the selling shareholders.

The table below sets forth certain information regarding the beneficial ownership of our common stock by all of the selling shareholders. The selling shareholders may from time to time offer the shares of common stock offered by this prospectus. We do not know when or in what amounts the selling shareholders may offer shares for resale and we cannot assure you that the selling shareholders will sell any or all of the shares offered by this prospectus.

The selling shareholders, their pledgees, donees, transferees or other successors in interest, may from time to time sell shares of our common stock directly to purchasers or indirectly to or through underwriters, broker-dealers or agents. The selling shareholders may sell all or part of their shares in one or more transactions at fixed prices, varying prices, prices at or related to the then-current market price or at negotiated prices. The selling shareholders will determine the specific offering price of the shares from time to time that, at that time, may be higher or lower than the market price of our common stock on the Nasdaq SmallCap Market. Usual and customary brokerage fees will be paid by each selling shareholder.

The selling shareholders and any underwriters, broker-dealers or agents participating in the distribution of the shares of our common stock may be deemed to be “underwriters” within the meaning of the Securities Act of 1933, and any profit from the sale of such shares by the selling shareholders and any compensation received by any underwriter, broker-dealer or agent may be deemed to be underwriting discounts under the Securities Act. The selling shareholders may agree to indemnify any underwriter, broker-dealer or agent that participates in transactions involving sales of the shares against certain liabilities, including liabilities arising under the Securities Act.

Because selling shareholders may be deemed to be “underwriters” within the meaning of the Securities Act, the selling shareholders will be subject to the prospectus delivery requirements of the Securities Act. We have informed the selling shareholders that the anti-manipulative provisions of Regulation M promulgated under the Exchange Act may apply to their sales in the market. With certain exceptions, Regulation M precludes the selling shareholders, any affiliated purchasers, and any broker-dealer or other person who participates in such distribution from bidding for or purchasing, or attempting to induce any person to bid for or purchase any security which is the subject of the distribution until the entire distribution is complete. Regulation M also prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security.

The method by which the selling shareholders, or their pledgees, donees, transferees or other successors in interest, may offer and sell their shares may include, but are not limited to, the following:

Any shares of common stock covered by this prospectus that qualify for sale under Rule 144 or Rule 144A of the Securities Act may be sold under Rule 144 or Rule 144A rather than under this prospectus. The shares of our common stock may be sold in some states only through registered or licensed brokers or dealers. In addition, in

some states, the shares of our common stock may not be sold unless they have been registered or qualified for sale or the sale is entitled to an exemption from registration.

The selling shareholders may enter into hedging transactions with broker-dealers or other financial institutions. In connection with such transactions, broker-dealers or other financial institutions may engage in short sales of our common stock in the course of hedging the positions they assume with selling shareholders. The selling shareholders may also enter into options or other transactions with broker-dealers or other financial institutions which require the delivery to such broker-dealer or other financial institution of the shares offered hereby, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

To the extent required by a particular offering, we will set forth in a prospectus supplement or, if appropriate, a post-effective amendment, the terms of such offering, including among other things, the number of shares of common stock to be sold, the public offering price, the names of any underwriters, dealers or agents and any applicable commissions or discounts. In addition, upon the company being notified by a selling shareholder that a donee or pedgee intends to sell more than 500 shares, a supplement to this prospectus will be filed.

To our knowledge, there are currently no plans, arrangements or understandings between any selling shareholder and any underwriter, broker-dealer or agent regarding the sale of shares of our common stock by the selling shareholders.

The selling shareholders will pay all fees, discounts and brokerage commissions in connection with any sales, including any fees to finders. We will pay all expenses of preparing and reproducing this prospectus, including expenses or compliance with state securities laws and filing fees with the SEC.

Under applicable rules and regulations under Regulation M under the Exchange Act, any person engaged in the distribution of the common stock may not simultaneously engage in market making activities, subject to certain exceptions, with respect to the common stock for a specified period set forth in Regulation M prior to the commencement of such distribution and until its completion. In addition and with limiting the foregoing, the selling stockholders will be subject to the applicable provisions of the Securities Act and the Exchange Act and the rules and regulations thereunder, including, without limitation, Regulation M, which provisions may limit the timing of purchases and sales of shares of the common stock by selling stockholders. The foregoing may affect the marketability of the common stock offered hereby.

Each selling stockholder may be deemed to be an “underwriter” as such term is defined in the Securities Act, and any commissions paid or discounts or concessions allowed to any such person and any profits received on resale of the securities offered hereby may be deemed to be underwriting compensation under the Securities Act.

There can be no assurance that any selling stockholders will sell any or all of the common stock pursuant to this prospectus. In addition, any common stock covered by this prospectus that qualifies for sale pursuant to Rule 144 of the Securities Act may be sold under Rule 144 rather than pursuant to this prospectus.

The validity of the shares of our common stock will be passed upon for us by Locke Liddell & Sapp LLP, Houston, Texas.

The report of KPMG covering the September 30, 2003 financial statements contains an explanatory paragraph that states that the Company has restated the consolidated balance sheets as of September 30, 2003 and 2002, and the related consolidated statements of operations, stockholders’ equity and comprehensive income (loss) and cash flows for the years ended September 30, 2003 and 2002.

The report of KPMG covering the September 30, 2003 financial statements contains an explanatory paragraph that states that the Company has suffered significant operating losses in 2003 and 2002 and does not currently have any external financing in place to fund working capital and debt requirements, which raise substantial doubt about the Company’s ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainly.

Section 7-108-402 of the Colorado Business Corporation Act (the “Act”) provides, generally, that the articles of incorporation may contain a provision eliminating or limiting the personal liability of a director to the corporation or its shareholders for monetary damages for breach of fiduciary duty as a director; except that any such provision may not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to the corporation or its shareholders, (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) acts specified in Section 7-108-403, or (iv) any transaction from which a director directly or indirectly derived an improper personal benefit. Such provision may not eliminate or limit the liability of a director for any act or omission occurring prior to the date on which such provision becomes effective. The Company’s articles of incorporation contain such a provision.

Section 7-109-103 of the Act provides, that a corporation organized under Colorado law shall be required to indemnify a person who is or was a director of the corporation or an individual who, while serving as a director of the corporation, is or was serving at the corporation’s request as a director, an officer, an agent, an associate, an employee, a fiduciary, a manager, a member, a partner, a promoter, or a trustee of, or to hold any similar position with, another domestic or foreign corporation or other person or of an employee benefit plan (a “Director”) of the corporation and who was wholly successful, on the merits or otherwise, in the defense of any threatened, pending, or completed action, suit, or proceeding, whether civil, criminal, administrative, or investigative and whether formal or informal (a “Proceeding”), in which he was a party, against reasonable expenses incurred by him in connection with the Proceeding, unless such indemnity is limited by the corporation’s articles of incorporation.

Section 7-109-102 of the Act provides, generally, that a corporation may indemnify a person made a party to a Proceeding because the person is or was a Director against any obligation incurred with respect to a Proceeding to pay a judgment, settlement, penalty, fine (including an excise tax assessed with respect to an employee benefit plan) or reasonable expenses incurred in the Proceeding if the person conducted himself or herself in good faith and the person reasonably believed, in the case of conduct in an official capacity with the corporation, the person’s conduct was in the corporation’s best interests and, in all other cases, his or her conduct was at least not opposed to the corporation’s best interests and, with respect to any criminal proceedings, the person had no reasonable cause to believe that his or her conduct was unlawful. A corporation may not indemnify a Director in connection with any Proceeding by or in the right of the corporation in which the Director was adjudged liable to the corporation or, in connection with any other Proceeding charging the Director derived an improper personal benefit, whether or not

involving actions in an official capacity, in which Proceeding the Director was judged liable on the basis that he or she derived an improper personal benefit. Any indemnification permitted in connection with a Proceeding by or in the right of the corporation is limited to reasonable expenses incurred in connection with such Proceeding.

Under Section 7-109-107 of the Act, unless otherwise provided in the articles of incorporation, a corporation may indemnify an officer, employee, fiduciary, or agent of the corporation to the same extent as a Director and may indemnify an officer, employee, fiduciary, or agent who is not a Director to a greater extent, if not inconsistent with public policy and if provided for by its bylaws, general or specific action of its board of directors or shareholders, or contract.

In addition, the Company’s articles of incorporation provide that each person who was or is made a party or is threatened to be made a party to or is otherwise involved in any Proceeding by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director, officer or employee of the Company or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans (an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent in any other capacity while serving as a director, officer, employee or agent, shall be indemnified and held harmless by the Company to the fullest extent authorized by the Act against all expense, liability and loss (including attorney’s fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith. Such indemnification shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the indemnitee’s heirs, executors and administrators; provided, however, that, with respect to Proceedings to enforce rights to indemnification, the Company shall indemnify any such indemnitee in connection with a Proceeding (or part thereof) initiated by such indemnitee only if such Proceeding (or part thereof) was authorized by the Board of Directors of the Company.

The Company’s articles require that the Company maintain insurance to protect itself and any Director, officer, employee or agent of the corporation or another corporation, partnership. joint venture, trust or other enterprise against any such expense, liability or loss, whether or not the corporation would have the power to indemnify such person against such expense, liability or loss under the Act.

The Company’s articles of incorporation provide that the Company shall indemnify any Director or officer, or former director or officer, or any person who may have served at its request as a director or officer of another corporation in which it owns shares of capital stock, or of which it is a creditor, and the personal representative of all such persons, against expenses actually and necessarily incurred by him in connection with the defense of any Proceeding in which he is made a party by reason of being or having been such director or officer, except in relation to matters as to which he shall be adjudged in such Proceeding, to be liable for negligence or misconduct in the performance of duty; but such indemnification shall not be deemed exclusive of any other rights to which such Director or officer may be entitled, under any by-law, agreement, vote of shareholders, or otherwise, nor shall anything herein contained restrict the right of the Company to indemnify or reimburse such person in any proper case, even though not specifically herein provided for.

(1) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

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

(3) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement to include any material information with respect to the plan of distribution not previously disclosed in this registration statement or any material change to such information in this registration statement.

(4) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

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

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Company’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other that the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, on May 17, 2004.
