All statements other than statements of historical facts included or incorporated in this Prospectus, including without limitation statements regarding the Company's financial position, business strategy, plans and objectives of management of the Company for future operations, and capital expenditures, are forward-looking statements. Although the Company believes that the expectations reflected in the forward-looking statements and the assumptions upon which such forward-looking statements are based are reasonable, it can give no assurance that such expectations and assumptions will prove to have been correct. Additional important factors that could cause actual results to differ materially from the Company's expectations ('Cautionary Statements") are disclosed in this Prospectus and the documents incorporated in this Prospectus. All written and oral forward-looking statements attributable to the Company or persons acting on its behalf subsequent to the date of this Prospectus are expressly qualified in their entirety by the Cautionary Statements. PROSPECTUS SUMMARY The following summary is qualified in its entirety by the more detailed information appearing elsewhere in this Prospectus and in the financial statements and other documents incorporated by reference into this Prospectus. Unless otherwise indicated, all references to annual or quarterly periods refer to the Company's fiscal year ending August 31. Investors should carefully consider the information set forth under the heading "RISK FACTORS". The Selling Stockholders may sell from time-to-time an aggregate of 415,689 Shares of the Company's Common Stock at prices obtainable on the Nasdaq or as otherwise negotiated. Each of the Selling Stockholders has informed the Company that he or she does not have any arrangements or agreements with any underwriters or broker/dealers to sell the Shares, and intends to contact various broker/dealers to identify prospective purchasers. Additionally, agents, brokers or dealers may acquire Shares or interests therein as a pledgee and may, from time to time, effect distributions of the Shares or interests in such capacity. Prior to this offering, the Selling Stockholders beneficially owned an aggregate of 415,689 shares, or less than one percent, of the Company's outstanding Common Stock, and each individual Selling Stockholder beneficially owned less than one percent of the Company's outstanding Common Stock. If the Selling Stockholders sell all the Shares offered hereby, the Selling Stockholders will not own any shares of the Company's Common Stock after this offering. See "OFFERING BY SELLING STOCKHOLDERS". The offering by the Selling Stockholders involves certain risks concerning the nature of the Company's business, and other matters. See "RISK FACTORS". The Company will not receive any of the proceeds from the sales of the Shares by the Selling Stockholders. 4 RISK FACTORS Prospective investors should carefully consider, together with the other information herein, the following factors that affect the Company. Concentration of Revenue - ------------------------- Approximately 75%, 88%, and 76% of the Company's total revenues in fiscal 1998, fiscal 1997, and fiscal 1996, respectively, were derived from contracts or subcontracts funded by the U.S. Government. These U.S. Government contracts include military weapons systems contracts, funded by the Department of Defense ("DOD") that accounted for approximately 55%, 53%, and 57% of the Company's total revenues in such years, respectively. The Company believes that the success and development of this business will continue to be dependent upon its ability to participate in U.S. Government contract programs. Accordingly, the Company's financial performance may be directly affected by changing U.S. Government procurement practices and policies. Other factors that could materially and adversely affect the Company's government contracting business and programs include budgetary constraints, changes in fiscal policies or available funding, changes in government programs or requirements (including proposals to abolish certain government agencies or departments, curtailing the U.S. Government's use of technology service firms, the adoption of new laws or regulations), technical developments and general economic conditions. These factors could cause U.S. Government agencies to exercise their rights to terminate existing contracts for convenience or not to exercise options to renew such contracts. In addition, certain of the Company's contracts individually contribute a significant percentage of the Company's revenues. The Company's seven largest contracts (by revenues) are with the U.S. Government and generated approximately 43% of the Company's total revenues for the year ended August 31, 1998. The Company expects revenues to continue to be concentrated in a relatively small number of large U.S. Government contracts. Termination of such contracts, or the Company's inability to renew or replace such contracts when they expire, could materially and adversely affect the Company's revenues and income. During fiscal year 1999, five of these seven contracts are expected to be recompeted. Risk of Reductions or Changes in Military Weapons Expenditures - --------------------------------------------------------------- Historically, a majority of the Company's revenues (55% for the year ended August 31, 1998) are related to U.S. military weapons systems. The U.S. military weapons budget has been declining in real terms since the mid-1980's, resulting in some cases in program delays, extensions, and cancellations. A further significant decline in U.S. military expenditures for weapons systems, or a reduction in the weapons systems portion of the defense budget, could materially and adversely affect the Company. While not anticipated, the loss or significant curtailment of the Company's U.S. military contracts would materially and adversely affect the Company's revenues and income. 5 Approximately 17% of the Company's revenues in fiscal 1998 were from contracts related to Ballistic Missile Defense, compared to 20% of revenues in fiscal 1997 and 26% of revenues in fiscal 1996 from such contracts. Strategic defense has existed for more than 26 years as a mission of DOD through activities such as the Ballistic Missile Defense ("BMD") program. If a decision were made to reduce substantially the scope of current BMD programs, management believes that many national and theater missile defense programs would continue to be funded by the U.S. Army and Air Force, and other DOD agencies. While the Company has expanded into other markets, a decision to reduce significantly or eliminate missile defense funding would have an adverse effect on the Company's revenues and income. Uncertainty Associated With Government Contracts - ------------------------------------------------- The Company performs its services under U.S. Government contracts that usually require performance over a period of one to five years. Long-term contracts may be conditioned upon continued availability of Congressional appropriations. Variances between anticipated budgets and Congressional appropriations may result in delay, reduction, or termination of such contracts. Contractors can experience revenue uncertainties with respect to available contract funding during the first quarter of the government's fiscal year beginning October 1, until differences between budget requests and appropriations are resolved. The Company's contracts with the U.S. Government and its prime contractors are subject to termination, in whole or in part, either upon default by the Company or at the convenience of the government. The termination for convenience provisions generally entitle the Company to recover costs incurred, settlement expenses, and profit on work completed prior to termination. Because the Company contracts to supply goods and services to the U.S. Government, it is also subject to other risks, including contract suspensions, audit adjustments, protests by disappointed bidders of contract awards which can result in the re-opening of the bidding process, and changes in government policies or regulations. Contract Profit Exposure - ------------------------- The Company's services are provided primarily through three types of contracts: fixed-price, time-and-materials and cost-reimbursement contracts. Fixed-price contracts require the Company to perform services under a contract at a stipulated price. Time-and-materials contracts reimburse the Company for the number of labor hours expended at an established hourly rate negotiated in the contract, plus the cost of materials incurred. Under cost reimbursement contracts, the Company is reimbursed for all actual costs incurred in performing the contract to the extent that such costs are within the contract ceiling and allowable under the terms of the contract, plus a fee or profit. 6 The Company assumes greater financial risk on fixed-price contracts than on either time-and-materials or cost-reimbursement contracts. As the Company increases its commercial business, it believes that an increasing percentage of its contracts will be fixed-priced. Failure to anticipate technical problems, estimate costs accurately, or control costs during performance of a fixed-price contract, may reduce the Company's profit or cause a loss. In addition, greater risks are involved under time-and-materials contracts than under cost-reimbursement contracts because the Company assumes the responsibility for the delivery of specified skill at a fixed hourly rate. Although management believes that adequate provision for its fixed-price and time-and-materials contracts is reflected in the Company's financial statements, no assurance can be given that this provision is adequate or that losses on fixed-price and time-and-materials contracts will not occur in the future. To compete successfully for business, the Company must satisfy client requirements at competitive rates. Although the Company continually attempts to lower its costs, there are other information technology and technical services companies that may provide the same or similar services at comparable or lower rates than the Company. Additionally, certain of the Company's clients require that their vendors reduce rates after services have commenced. The Company's success will also depend upon its ability to attract, retain, train, and motivate highly skilled employees, particularly in the areas of information technology, where such employees are in great demand. Acquisition Strategy - --------------------- Expansion through acquisitions is an important component of the Company's overall business strategy. The Company has successfully completed ten strategic acquisitions and alliances since September 1, 1994, most of which have centered on information technology (IT) and healthcare information services markets. Since the respective dates of the acquisitions, the Company has integrated these acquired entities in order to draw on the Company's base of technical expertise and capabilities in designing solutions for government, commercial, and healthcare clients. The Company's continued ability to grow by acquisitions is dependent upon, and may be limited by, the availability of compatible acquisition candidates at reasonable prices, the Company's ability to fund or finance acquisitions on acceptable terms, and the Company's ability to maintain or enhance the profitability of any acquired business. Competition - ------------ The information services industry in which the Company operates is highly fragmented with no single company or small group of companies in a dominant position. The Company's competitors include large, diversified firms with substantially greater financial resources and larger technical staffs than those of the Company. Some of the large competitors offer services in a number of markets which overlap many of the same areas in which the Company offers services, while certain companies are focused on only one or a few of these markets. The firms which compete with the Company are consulting firms, computer services firms, applications software companies and accounting firms, as well as the computer service arms of computer manufacturing companies and defense and aerospace firms. 7 As part of the Company's business strategy to enter new markets, the Company intends to pursue large systems integration contracts in both the government and commercial markets, although competition for such contracts is intense and many of the Company's competitors have greater resources than the Company. While such contracts are working capital intensive, requiring large equipment and software purchases to be funded by the Company before payment from the customer, the Company believes such contracts offer attractive revenue growth and margin expansion opportunities for the Company's range of technical expertise and capabilities. Attraction and Retention of Professional Staff - ----------------------------------------------- The Company's success will depend in part upon its ability to attract, retain, train and motivate highly skilled employees, particularly in the area of information technology. There is significant competition for employees with the information technology skills required to perform the services the Company offers. Qualified information technology professionals are in great demand and are likely to remain a limited resource for the foreseeable future. There can be no assurance that the Company will be successful in attracting a sufficient number of highly skilled employees in the future or that it will be successful in retaining, training and motivating the employees it is able to attract and any inability to do so could impair the Company's ability to perform adequately its existing contracts and to bid for or obtain new contracts. Variability of Quarterly Operating Results - ------------------------------------------- The Company's revenues and earnings may fluctuate from quarter to quarter based on such factors as the number, size, and scope of projects in which the Company is engaged, the contractual terms and degree of completion of such projects, expenditures required by the Company in connection with such projects, any delays incurred in connection with such projects, employee utilization rates, the adequacy of provisions for losses, the accuracy of estimates of resources required to complete ongoing projects, and general economic conditions. Under certain contracts, the Company is required to purchase, integrate and deliver to the customer large amounts of computer processing systems and other equipment. Revenues are accrued as costs to deliver these systems are incurred, and as a result, quarterly revenues will be impacted by fluctuations related to equipment purchases which occur on a periodic basis depending on contract terms and modifications. THE COMPANY General - ------- The Company is a leading provider of technical and information technology (IT) services, including information processing, systems development and systems integration. The Company provides these services to a wide range of clients, including the DOD, other federal agencies, state and local governments, healthcare and insurance organizations, and commercial enterprises. The Company was founded in 1976 to develop specialized optical sensing capabilities for military weapons and ballistic defense programs. Until fiscal year 1991, virtually all of the Company's revenues were derived under contracts with the federal government relating to high technology weapons systems, strategic missile defense and other related 8 aerospace technologies. Areas of particular strength have included tactical technology, smart sensing systems, simulations, data processing, systems engineering and systems integration (including software development, networking, hardware acquisition and installation, user training and system operation and maintenance). Beginning in fiscal year 1991, in response to increasing budget pressure on military procurements, the Company strategically began to develop applications for its technical capabilities outside its traditional core military business. Although the Company's core military business has continued to grow, the Company has successfully entered the markets for other government information technology solutions, as well as information technology solutions in the healthcare industry and other commercial markets. The Company's business strategy consists of three key elements: (i) maintain the Company's leadership in technology; (ii) apply the Company's technology to create solutions for new clients; and (iii) make strategic acquisitions and form alliances to expand the business of the Company and gain industry knowledge. The Company's business and financial performance are subject to risks and uncertainties, including those discussed above. See "RISK FACTORS." The Company is organized in four strategic business units, reflecting the particular market focus of each line of business. The Defense and Intelligence unit (formerly referred to as Nichols Federal) provides technical services primarily to U.S. Government defense agencies. The Government Information Technology unit (formerly referred to as Nichols InfoFed) provides information and technology solutions and services to a variety of governmental agencies. The Commercial Information Technology unit (formerly referred to as Nichols Infotec) provides information and technology services to various commercial clients, other than healthcare clients. The Healthcare Information Technology unit (formerly referred to as Nichols TXEN) provides information services to clients in the healthcare and insurance industries. The Company is currently evaluating whether the services and products provided to the insurance industry should continue to be included with Nichols TXEN or reorganized into Nichols InfoTec. For the year ended August 31, 1998, the percentage of total revenues attributable to the four business units was approximately 55% for Defense and Intelligence, 24% for Government Information Technology, 10% for Commercial Information Technology, and 11% for Healthcare Information Technology. The Company's executive offices are located at 4090 South Memorial Parkway, Huntsville, Alabama 35815-1502, and its telephone number is (256) 883-1140. 9 Year 2000 - --------- Overview Historically, certain computerized systems have had two digits rather than four digits to define the applicable year, which could result in recognizing a date using "00" as the year 1900 rather than the year 2000. This could cause significant software failures or miscalculations and is generally referred to as the "Year 2000" problem. The Company recognizes that the impact of the Year 2000 problem extends beyond its computer hardware and software and may affect utility and telecommunication services, as well as the systems of customers and suppliers. In response to the Year 2000 problem, the Company has developed a compliance program to evaluate and address date related problems with the Company's internal systems, services, products, and the systems and products of the Company's vendors and suppliers. The compliance program is managed by the Vice President of Corporate Information Systems and Services, and is patterned after the United States General Accounting Office (GAO) and Office of Management and Budget project management model. The Company's Year 2000 compliance program includes five major phases: Awareness Phase. The Year 2000 problem is defined and managers at the executive level are educated about potential date related problems and the potential impact to the Company and its customers from Year 2000 date handling errors. A Year 2000 program team is established and an overall strategy is developed. Assessment Phase. The Year 2000 program team assesses the Year 2000 impact on the Company by: (i) identifying core business areas and processes; (ii) performing an inventory and analysis of systems supporting the core business areas; (iii)contacting third party service providers, and software and hardware vendors to determine Year 2000 issues and their plans for becoming Year 2000 compliant; and (iv) prioritizing conversion or replacement of systems. Renovation Phase. The Year 2000 program team corrects Year 2000 problems identified in the Assessment Phase by modifying program software, updating databases, replacing systems or utilizing other appropriate methods. Implementation Phase. The Year 2000 program team tests, verifies, and validates converted or replaced systems, applications, databases and utilities within a limited operational environment. Validation Phase. The Year 2000 program team fully implements converted or replaced systems, applications, databases and utilities. The Year 2000 program team also performs extensive testing of all system changes. 10 As part of the awareness phase the Company has reviewed - Mission Essential Software Systems - Mission Essential Computational Systems (hardware) - Mission Essential Facilities Systems, including elevators, heating and air conditioning systems, photocopying machines and utility services - Mission Essential Network Systems - Customer Software Services, provided by the Company's business units - Mission Essential Vendor-Supplied Software and Services The Company considers a system "mission essential" if a failure in that system would materially disrupt the ability of the Company to perform contractual services or to process business information in a timely manner. The Company monitors the status of its Year 2000 compliance program and routinely updates its Intranet to provide compliance data to its managers and employees. The Company provides services and products to the United States Government pursuant to specific contractual terms and exact specifications. The Company believes that it will be responsible for upgrading only those services or products that specify Year 2000 compliance and do not yet meet this requirement. The Company is not currently aware of any such services or products. Status and Timetable for Year 2000 Compliance Nichols Research has developed a master timetable for its year 2000 compliance program. The status of each major category of mission essential systems is as follows: SYSTEM CATEGORY PHASE ESTIMATED DATE FOR COMPLIANCE - ------------------------------------------------------ ---------------- -------------------------------------------- Mission Essential Software Systems Renovation December 1998 - ------------------------------------------------------ ---------------- -------------------------------------------- Mission Essential Computational Systems Renovation December 1998 - ------------------------------------------------------ ---------------- -------------------------------------------- Mission Essential Network Systems Renovation December 1998 - ------------------------------------------------------ ---------------- -------------------------------------------- Mission Essential Facilities Systems Assessment Unknown - ------------------------------------------------------ ---------------- -------------------------------------------- Mission Essential Customer Systems Renovation December 1998 - ------------------------------------------------------ ---------------- -------------------------------------------- Mission Essential Vendor-Supplied Software & Services Assessment Unknown - ------------------------------------------------------ ---------------- -------------------------------------------- 11 The phases listed above represent the status of the majority of products within each category. There may be, within each "system," components at a lower or higher phase in the Year 2000 assessment. For example, although Mission Essential Vendor-Supplied Software and Services is rated in the Assessment phase, many of the Company's vendors have already been contacted and have supplied letters or referenced web pages certifying their Year 2000 compliance. The Vice-President of Corporate Information Systems & Services maintains compliance letters and referenced web page addresses. While Nichols Research estimates that its internal systems will be Year 2000 compliant by the end of calendar year 1998, there can be no assurance that the third-party supplied software, hardware and services included in the essential facilities and vendor-supplied services categories will be Year 2000 compliant, or that these third-parties will not suffer a Year 2000 business disruption that may adversely affect the Company's business, financial condition or results of operations. Contingency Plans Because the Company's Year 2000 conversions are expected to be completed prior to any potential disruption to the Company's business, the Company has not yet completed the development of a comprehensive Year 2000 contingency plan. However, the Company has minimized its exposure to Year 2000 failures of vendor supplied products by adding Year 2000 compliance as a standard condition to its purchase orders. These contracts also reference the Federal Acquisition Regulation 39.106, which addresses Year 2000 compliance issues. The Company is currently negotiating a Risk Management Insurance Policy designed to protect the Company in the event that it is involved in litigation arising from errors and omissions relating to Year 2000 issues. If the Company determines that its business is at material risk of disruption due to the Year 2000 problem, or anticipates that its Year 2000 conversions will not be completed in a timely fashion, the Company will work to develop a detailed contingency plan. Cost for Year 2000 Compliance The Company believes that the total cost of its Year 2000 compliance activity will not be material to the Company's operation, liquidity and capital resources. The Company estimates that the total cost for its Year 2000 compliance will be $688,500 which represents 11,475 hours of analysis, modification and testing, and $34,500 for new equipment purchases. To date, the Company has completed 6,850 hours of Year 2000 compliance work, and purchased new equipment valued at $27,000, for a total cost of $438,000. Year 2000 Risks Faced by Nichols Research Although the Company believes that its Year 2000 compliance program is comprehensive, the Company may not be able to identify, successfully remedy or assess all date-handling problems in its business systems or operations or those of its customers and suppliers. As a result, the Year 2000 problem could have a materially adverse affect on the Company's business financial condition or results of operation. 12 FIVE-YEAR FINANCIAL SUMMARY Pro forma Pro forma 1998 1998 1997 1997 1996 1995 1994 ---- ---- ---- ---- ---- ---- ---- Revenues $ 427,043,000 $427,043,000 $ 398,142,000 $ 398,142,000 $256,605,000 $ 180,698,000 $149,874,000 Net income $16,958,000*** $ 14,423,000 13,199,000** $ 1,199,000 $ 10,063,000 $ 7,651,000 $ 6,858,000 Earnings per common share * $ 1.25 $ 1.06 $ 1.09 $ 0.10 $ 1.00 $ 0.80 $ 0.72 Earnings per common share assuming dilution* $ 1.20 $ 1.02 $ 1.04 $ 0.09 $ 0.94 $ 0.77 $ 0.70 Stockholders' equity $ 166,472,000 $166,472,000 $ 146,968,000 $ 146,968,000 $115,052,000 $ 69,358,000 $ 58,365,000 Long-term debt $ 2,948,000 $ 2,948,000 $ 4,025,000 $ 4,025,000 $ 4,784,000 $ 5,366,000 $ 4,328,000 Goodwill and other intangibles, net $ 54,214,000 $ 54,214,000 $ 48,130,000 $ 48,130,000 $21,004,000 $ 8,803,000 $ - Total assets $ 224,061,000 $224,061,000 $ 210,132,000 $ 210,132,000 $165,321,000 $ 103,283,000 $82,318,000 * As adjusted for a three-for-two stock split effective October 21, 1996. ** Excludes a $12.0 million write off of purchased in-process research and development. *** Excludes $4.1 million of pretax special charges. NOTE: All prior periods have been restated to reflect the fiscal year 1998 merger with Welkin, which was accounted for as a pooling of interests. 13 OFFERING BY SELLING STOCKHOLDERS The Company is registering the sale of an aggregate of 415,689 Shares of Common Stock by the Selling Stockholders. The Selling Stockholders may sell their Common Stock at such prices as they are able to obtain in the market or as otherwise negotiated. The Company will receive no proceeds from the sale of Common Stock by the Selling Stockholders. Additionally, agents, brokers or dealers may acquire Shares or interests therein as a pledgee and may, from time to time, effect distributions of the Shares or interests in such capacity. The Shares offered by the Selling Stockholders were acquired from the Company in connection with the merger of a wholly-owned subsidiary of the Company with and into Welkin Associates, Ltd. (the "Welkin Acquisition'). The Welkin Acquisition was completed pursuant to the terms of an Agreement and Plan of Merger dated June 26, 1998 (the "Merger Agreement"). As a result of the consummation of the merger, all issued and outstanding shares of Welkin Associates, Ltd. were exchanged for 415,689 shares of the Company's Common Stock. As part of the Merger Agreement, the Company agreed to effect a registration of all shares of the Company's Common Stock received by the Selling Stockholders in the Welkin Acquisition in order to permit the Selling Stockholders to effect sales of such Shares from time to time in the market or in privately negotiated transactions. Accordingly, the Company has filed with the Commission, under the Securities Act, a Registration Statement on Form S-3, of which this Prospectus is a part, with respect to the resale of the Shares from time to time on the Nasdaq National Market or in privately negotiated transactions. The Company has agreed to use reasonable efforts to keep such Registration Statement in effect for up to two years from the date of its effectiveness or, if earlier, until the distribution contemplated in this Prospectus is completed. Each of Carl W. Monk, Jr., David Thomas, and Alan A. Ross was a director of Welkin Associates, Ltd. ("Welkin") at the time that Welkin became a wholly-owned subsidiary of the Company on July 28, 1998. In addition, Carl W. Monk was President, Treasurer, as well as a stockholder. Each of Alan A. Ross and Jose Jimenez was a Vice President and stockholder, and Patricia Toomey was Secretary and a stockholder at that time. The following table sets forth the name of each Selling Stockholder, the number of shares of Common Stock owned by each Selling Stockholder before the offering, the number of shares of Common Stock to be sold by each Selling Stockholder, the number of shares owned by each Selling Stockholder after the offering, and the percentage of shares of Common Stock owned after the offering. For purposes of this table, the Company has assumed the sale of all Shares registered hereby, although the Company is not aware of any present intention of any Selling Shareholder to sell such Shares. 14 Number of Shares Number of Percentage of Owned Number of Shares Owned Shares Before Shares to After Owned After Name Offering Be Sold Offering Offering - ----------- ------------ --------- ------------ --------------- Carl W.

See "OFFERING BY SELLING STOCKHOLDERS." PLAN OF DISTRIBUTION All or a portion of the Shares offered hereby by the Selling Stockholders may be delivered and/or sold from time to time in transactions on the Nasdaq National Market, in privately negotiated transactions, or by a combination of both (which compensation to a particular broker-dealer might be in excess of customary commissions). There is no assurance that any of the Selling Stockholders will sell any or all of the Shares offered by them. Any Selling Stockholder and any broker-dealer that participates in the distribution may under certain circumstances be deemed to be "underwriters" within the meaning of the Securities Act, and any commissions received by such broker-dealers and any profits realized on the resale of Shares may be deemed to be underwriting discounts and commissions under the Securities Act. Each Selling Stockholder may agree to indemnify such broker-dealers against certain liabilities, including liabilities under the Securities Act. In addition, the Company has agreed to indemnify in certain circumstances the Selling Stockholders against certain liabilities including liabilities arising under the Securities Act. The Selling Stockholders have agreed to indemnify in certain circumstances the Company against certain liabilities. Selling Stockholders also may resell all or a portion of the Shares in open market transactions in reliance upon Rule 144 under the Securities Act, provided they meet the criteria and conform to the requirements of such Rule. Upon the Company being notified by a Selling Stockholder that any material arrangement has been entered into with a broker-dealer for the sale of Shares through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, a supplement to this Prospectus will be filed, if required, pursuant to Rule 424(b) under the Securities Act, disclosing (i) the name of each such Selling Stockholder and of the participating broker-dealer(s), (ii) the number of Shares involved, (iii) the price at which such Shares were sold, (iv) the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable, (v) that such broker-dealer(s) did not conduct any investigation to verify the information set out or incorporated by reference in the Prospectus and (vi) other facts material to the transaction. In addition, upon the Company being notified by a Selling Stockholder that a donee or pledgee intends to sell more than 500 shares, a supplement to this Prospectus will be filed.

Other Expenses Of Issuance And Distribution. - -------- -------------------------------------------- The estimated expenses of the Offering described in this Registration Statement are as follows: Registration Fee $ 2,897.00 Nasdaq Additional Listing Fee $ 8,314.00 Printing and Engraving Expenses* $ 50.00 Accounting Fees and Expenses* $ 2,500.00 Legal Fees and Expenses* $ 6,000.00 Registrar and Transfer Agent Fees* $ 1,575.00 ================= Total* $ 21,336.00 ================= - ------------------------ *Estimated Item 15. Indemnification Of Directors And Officers. - ----------------------------------------------------- Section 145 of the Delaware General Corporation Law permits indemnification by the Company of any director, officer, employee or agent of the Company or person who is serving or was serving at the Company's request as a director, officer, employee or agent of another corporation or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement, actually and reasonably incurred by him in connection with the defense of any threatened, pending or completed action (whether civil, criminal, administrative or investigative), to which he is or may be a party by reason of having been such director, officer, employee or agent provided that he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding had no reasonable cause to believe his conduct was unlawful. The Company also has the power under Section 145 to indemnify persons set forth above from threatened, pending or completed actions or suits by or in the right of the Company to procure a judgment in its favor by reason of the fact that such person was a director, officer, employee or agent 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 enterprise against expenses actually and reasonably incurred by him in connection with the defense or settlement of the action if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company, except that no indemnification can be made with regard to any claim, issue or matter as to which the person II-1 has been adjudged to be liable for negligence or misconduct in the performance of his duty to the Company unless and only to the extent that the Delaware Court of Chancery or the court in which the action was brought determines that the person was fairly and reasonably entitled to indemnity. Any indemnification (unless ordered by a court) must be made by the Company only as authorized in the specific case upon a determination that indemnification of the person is proper in the circumstances because he has met the applicable standards of conduct. The determination must be made by the Board of Directors by a majority vote of a quorum consisting of directors who are not parties to the action, or if a quorum is not obtainable or, even if obtainable, a quorum of disinterested directors so directs, by independent counsel in a written opinion, or by the stockholders. The Company may pay the expenses of an action in advance of final disposition if authorized by the Board of Directors in a specific case, upon receipt of an undertaking by the person to be indemnified to repay any such advances unless it shall ultimately be determined that such person is entitled to be indemnified by the Company as authorized by law. Article Nine of the Company's By-laws provides for indemnification of the Company's directors, officers, employees or agents to the extent permitted by Section 145 of the Delaware General Corporation Law. Article Nine of the Company's By-laws further provides that the Company may purchase and maintain insurance on behalf of those persons described above as eligible for indemnification for liability arising out of such person's duties or status with the Company whether or not indemnification in respect of such liability would be permissible. The Company has in effect an officers and directors liability insurance policy with National Union Fire Insurance Company of Pittsburgh. The policy provides indemnity to the directors and officers of the Company for the loss arising from any claim by reason of a wrongful act where there is no corporate indemnification. The insurance provides for the Company to be reimbursed for any indemnification it may be required by statute or the Company's By-laws to make to any of its directors and officers in connection with a claim by reason of a wrongful act. Pursuant to exclusions, the policy covers negligent acts, errors, omissions or breach of duty by a director or officer. The principal exclusions from coverage include the following: (i) claims involving various violations of Section 16(b) of the Securities Exchange Act of 1934; (ii) dishonest acts; and (iii) libel, slander, or non-monetary damages. The policy has no deductible amount per director or officer for each loss. A $500,000 deductible self-insurance retention applies to the Company. The limit of liability under the policy is $5,000,000 in the aggregate annually in excess of deductibles and participations. II-2 Item 16.

Item 17. Undertakings. - --------- ------------- The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act. (ii)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 a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement. (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement. Provided, however, that paragraphs (1)(i) and (1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in the periodic reports filed by the registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the registration statement. II-3 (2) That, for the purpose of determining any liability under the Securities Act, 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. (3) 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. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's Annual Report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to 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. The undersigned Registrant hereby undertakes that: (1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective. (2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus 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. 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 Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than 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 Act and will be governed by the final adjudication of such issue. II-4 SIGNATURES 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 has duly caused this Amendment No. 4 to the Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Huntsville, State of Alabama, on this 31st day of December, 1998.
