OUR COMPANY
     We are a rapidly growing information technology consulting firm serving Global 2000 and midsize companies in the central United States. We help our clients gain competitive advantage by using Internet-based technologies to make their businesses more responsive to market opportunities and threats, strengthen relationships with customers, suppliers and partners, improve productivity and reduce information technology costs. We design, build and deliver software solutions using a core set of software products developed by our partners. These products, which are based on open standards such as the Java 2 Enterprise Edition, or J2EE, are commonly referred to as middleware and include application servers, enterprise application integration platforms, business process management, business activity monitoring and business intelligence applications and enterprise portal software. Using these products, our solutions enable our clients to operate a real-time enterprise that dynamically adapts business processes and the systems that support them to the changing demands of an increasingly global, Internet-driven and competitive marketplace.
     Through our experience in developing and delivering eBusiness integration solutions for more than 425 Global 2000 and midsize companies, we have acquired significant domain expertise that we believe differentiates our firm. We use small, expert project teams that we believe deliver high-value, measurable results by working collaboratively with clients and their partners through a user-centered, technology-based and business-driven solutions methodology. We believe this approach enhances return-on-investment for our clients by significantly reducing the time and risk associated with designing and implementing eBusiness integration solutions.
     We believe that the central United States represents an attractive geographic market and that our focus on this region and our network of nine offices throughout the central United States are additional competitive differentiators. We believe this geographic focus makes us the partner of choice both for Global 2000 and midsize companies in the area that seek business and technology consulting services and for software vendors that seek consulting firm partners to sell and deliver solutions that use their products.
     We place strong emphasis on building lasting relationships with clients. In fiscal years 2002, 2003 and 2004, 81%, 85% and 91% of revenue, respectively, excluding from the calculation for any single period revenue from acquisitions completed in that single period, was derived from customers that were clients in the prior year. We have also built meaningful partnerships with software providers, most notably IBM, whose products we use to design and implement solutions for our clients. These partnerships enable us to reduce our cost of sales and sales cycle times and increase win rates through leveraging our partners’ marketing efforts and endorsements.
     We are expanding through a combination of organic growth and acquisitions and have completed five acquisitions since January 1, 2004—Genisys Consulting in April 2004, Meritage Technologies in June 2004, ZettaWorks in December 2004, iPath Solutions in June 2005 and Vivare in September 2005. We believe that information technology consulting is a fragmented industry and that there are a substantial number of privately held information technology consulting firms in our target markets that can be acquired on financially accretive terms. We have a track record of successfully identifying, executing and integrating acquisitions that add strategic value to our business. Over the past five years, we have acquired and integrated nine privately held information technology consulting firms, three of which were acquired in 2004 and two in 2005. We believe that we can achieve significantly faster growth in revenues and profitability through a combination of organic growth and acquisitions than we could through organic growth alone.

RISK FACTORS
     You should carefully consider the following risk factors together with the other information contained in or incorporated by reference into this prospectus before you decide to buy our common stock. If any of these risks actually occur, our business, financial condition, operating results or cash flows could be materially adversely affected. This could cause the trading price of our common stock to decline and you may lose part or all of your investment.
Risks Related to Our Business
Prolonged economic weakness in the Internet software and services market could adversely affect our business, financial condition and results of operations.
     The market for middleware and Internet software and services has changed rapidly over the last six years. The market for middleware and Internet software and services expanded dramatically during 1999 and most of 2000, but declined significantly in 2001 and 2002. Market demand for Internet software and services began to stabilize and improve throughout 2003, 2004 and 2005, but this trend may not continue. Our future growth is dependent upon the demand for Internet software and services, and, in particular, the information technology consulting services we provide. Demand and market acceptance for middleware and Internet services are subject to a high level of uncertainty. Prolonged weakness in the middleware and Internet software and services industry has caused in the past, and may cause in the future, business enterprises to delay or cancel information technology projects, reduce their overall budgets and/or reduce or cancel orders for our services. This, in turn, may lead to longer sales cycles, delays in purchase decisions, payment and collection, and may also result in price pressures, causing us to realize lower revenues and operating margins. If companies cancel or delay their business and technology initiatives or choose to move these initiatives in-house, our business, financial condition and results of operations could be materially and adversely affected.
We may not be able to attract and retain information technology consulting professionals, which could affect our ability to compete effectively.
     Our business is labor intensive. Accordingly, our success depends in large part upon our ability to attract, train, retain, motivate, manage and effectively utilize highly skilled information technology consulting professionals. Additionally, our technology professionals are primarily at-will employees. We also use independent subcontractors where appropriate. Failure to retain highly skilled technology professionals would impair our ability to adequately manage staff and implement our existing projects and to bid for or obtain new projects, which in turn would adversely affect our operating results.
Our success will depend on attracting and retaining senior management and key personnel.
     Our industry is highly specialized and the competition for qualified management and key personnel is intense. We expect this to remain so for the foreseeable future. We believe that our success will depend on retaining our senior management team and key technical and business consulting personnel. Retention is particularly important in our business as personal relationships are a critical element of obtaining and maintaining strong relationships with our clients. In addition, as we rapidly grow our business, our need for senior experienced management and delivery personnel increases substantially. If a significant number of these individuals stop working for us, or if we are unable to attract top talent, our level of management, technical, marketing and sales expertise could diminish or otherwise be insufficient for our growth. We may be unable to achieve our revenue and operating performance objectives unless we can attract and retain technically qualified and highly skilled sales,

3


Table of Contents

technical, business consulting, marketing and management personnel. These individuals would be difficult to replace, and losing them could seriously harm our business.
We may have difficulty in identifying and competing for strategic acquisition and partnership opportunities.
     Our business strategy includes the pursuit of strategic acquisitions. We may acquire or make strategic investments in complementary businesses, technologies, services or products, or enter into strategic partnerships or alliances with third parties in the future in order to expand our business. We may be unable to identify suitable acquisition, strategic investment or strategic partnership candidates, or if we do identify suitable candidates, we may not complete those transactions on terms commercially favorable to us, or at all. If we fail to identify and successfully complete these transactions, our competitive position and our growth prospects could be adversely affected. In addition, we may face competition from other companies with significantly greater resources for acquisition candidates, making it more difficult for us to acquire suitable companies on favorable terms.
Pursuing and completing potential acquisitions could divert management’s attention and financial resources and may not produce the desired business results.
     We do not have specific personnel dedicated to pursuing and making strategic acquisitions. As a result, if we pursue any acquisition, our management could spend a significant amount of time and financial resources to pursue and integrate the acquired business with our existing business. To pay for an acquisition, we might use capital stock, cash or a combination of both. Alternatively, we may borrow money from a bank or other lender. If we use capital stock, our stockholders will experience dilution. If we use cash or debt financing, our financial liquidity may be reduced and the interest on any debt financing could adversely affect our results of operations. From an accounting perspective, an acquisition may involve amortization or the write-off of significant amounts of intangible assets that could adversely affect our results of operations.
     Despite the investment of these management and financial resources, and completion of due diligence with respect to these efforts, an acquisition may not produce the anticipated revenues, earnings or business synergies for a variety of reasons, including:
    difficulties in the integration of the technologies, services and personnel of the acquired business;
 
    the failure of management and acquired services personnel to perform as expected;
 
    the risks of entering markets in which we have no, or limited, prior experience;
 
    the failure to identify or adequately assess any undisclosed or potential liabilities or problems of the acquired business including legal liabilities;
 
    the failure of the acquired business to achieve the forecasts we used to determine the purchase price; or
 
    the potential loss of key personnel of the acquired business.
     These difficulties could disrupt our ongoing business, distract our management and colleagues, increase our expenses and materially and adversely affect our results of operations.

The market for the information technology consulting services we provide is competitive, has low barriers to entry and is becoming increasingly consolidated, which may adversely affect our market position.
     The market for the information technology consulting services we provide is competitive, rapidly evolving and subject to rapid technological change. In addition, there are relatively low barriers to entry into this market and therefore new entrants may compete with us in the future. For example, due to the rapid changes and volatility in our market, many well-capitalized companies, including some of our partners, that have focused on sectors of the Internet software and services industry that are not competitive with our business may refocus their activities and deploy their resources to be competitive with us.
     Our future financial performance will depend, in large part, on our ability to establish and maintain an advantageous market position. We currently compete with regional and national information technology consulting firms, and, to a limited extent, offshore service providers and in-house information technology departments. Many of the larger regional and national information technology consulting firms have substantially longer operating histories, more established reputations and potential partner relationships, greater financial resources, sales and marketing organizations, market penetration and research and development capabilities, as well as broader product offerings and greater market presence and name recognition. We may face increasing competitive pressures from these competitors as the market for Internet software and services continues to grow. This may place us at a disadvantage to our competitors, which may harm our ability to grow, maintain revenue or generate net income.
     In recent years, there has been substantial consolidation in our industry, and we expect that there will be significant additional consolidation in the near future. As a result of this increasing consolidation, we expect that we will increasingly compete with larger firms that have broader product offerings and greater financial resources than we have. We believe that this competition could have a significant negative effect on our marketing, distribution and reselling relationships, pricing of services and products and our product development budget and capabilities. Any of these negative effects could significantly impair our results of operations and financial condition. We may not be able to compete successfully against new or existing competitors.
Our business will suffer if we do not keep up with rapid technological change, evolving industry standards or changing customer requirements.
     Rapidly changing technology, evolving industry standards and changing customer needs are common in the Internet software and services market. We expect technological developments to continue at a rapid pace in our industry. Technological developments, evolving industry standards and changing customer needs could cause our business to be rendered obsolete or non-competitive, especially if the market for the core set of eBusiness solutions and software platforms in which we have expertise does not grow or if such growth is delayed due to market acceptance, economic uncertainty or other conditions. Accordingly, our success will depend, in part, on our ability to:
    continue to develop our technology expertise;
 
    enhance our current services;
 
    develop new services that meet changing customer needs;
 
    advertise and market our services; and

5


Table of Contents

    influence and respond to emerging industry standards and other technological changes.
     We must accomplish all of these tasks in a timely and cost-effective manner. We might not succeed in effectively doing any of these tasks, and our failure to succeed could have a material and adverse effect on our business, financial condition or results of operations, including materially reducing our revenue and operating results.
     We may also incur substantial costs to keep up with changes surrounding the Internet. Unresolved critical issues concerning the commercial use and government regulation of the Internet include the following:
    security;
 
    intellectual property ownership;
 
    privacy;
 
    taxation; and
 
    liability issues.
     Any costs we incur because of these factors could materially and adversely affect our business, financial condition and results of operations, including reduced net income.
A significant portion of our revenue is dependent upon building long-term relationships with our clients and our operating results could suffer if we fail to maintain these relationships.
     Our professional services agreements with clients are in most cases terminable on 10 to 30 days’ notice. A client may choose at any time to use another consulting firm or choose to perform services we provide through their own internal resources. Accordingly, we rely on our clients’ interests in maintaining the continuity of our services rather than on contractual requirements. Termination of a relationship with a significant client or with a group of clients that account for a significant portion of our revenues could adversely affect our revenues and results of operations.
If we fail to meet our clients’ performance expectations, our reputation may be harmed.
     As a services provider, our ability to attract and retain clients depends to a large extent on our relationships with our clients and our reputation for high quality services and integrity. We also believe that the importance of reputation and name recognition is increasing and will continue to increase due to the number of providers of information technology services. As a result, if a client is not satisfied with our services or does not perceive our solutions to be effective or of high quality, our reputation may be damaged and we may be unable to attract new, or retain existing, clients and colleagues.
We may face potential liability to customers if our customers’ systems fail.
     Our eBusiness integration solutions are often critical to the operation of our customers’ businesses and provide benefits that may be difficult to quantify. If one of our customers’ systems fails, the customer could make a claim for substantial damages against us, regardless of our responsibility for that failure. The limitations of liability set forth in our contracts may not be enforceable in all instances and may not otherwise protect us from liability for damages. Our insurance coverage may not continue to be available on reasonable terms or in sufficient amounts to cover one or more large claims. In addition, a

6


Table of Contents

given insurer might disclaim coverage as to any future claims. If we experience one or more large claims against us that exceed available insurance coverage or result in changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, our business and financial results could suffer.
The loss of one or more of our significant software partners would have a material adverse effect on our business and results of operations.
     Our partnerships with software vendors enable us to reduce our cost of sales and increase win rates through leveraging our partners’ marketing efforts and strong vendor endorsements. The loss of one or more of these relationships and endorsements could increase our sales and marketing costs, lead to longer sales cycles, harm our reputation and brand recognition, reduce our revenues and adversely affect our results of operations.
     In particular, a substantial portion of our solutions are built on IBM WebSphere platforms and a significant number of our clients are identified through joint selling opportunities conducted with IBM, through sales leads obtained from our relationship with IBM and through a services agreement we have with IBM. Revenue from IBM was approximately 11% and 29% of total revenue for the six-months ended June 30, 2005 and 2004, respectively. The loss of our relationship with, or a significant reduction in the services we perform for IBM would have a material adverse effect on our business and results of operations.
Our quarterly operating results may be volatile and may cause our stock price to fluctuate.
     Our quarterly revenue, expenses and operating results have varied in the past and may vary significantly in the future. In addition, many factors affecting our operating results are outside of our control, such as:
    demand for Internet software and services;
 
    customer budget cycles;
 
    changes in our customers’ desire for our partners’ products and our services;
 
    pricing changes in our industry;
 
    government regulation and legal developments regarding the use of the Internet; and
 
    general economic conditions.
     As a result, if we experience unanticipated changes in the number or nature of our projects or in our employee utilization rates, we could experience large variations in quarterly operating results and losses in any particular quarter.
Our services revenues may fluctuate quarterly due to seasonality or timing of completion of projects.
     We may experience seasonal fluctuations in our services revenues. We expect that services revenues in the fourth quarter of a given year may typically be lower than in other quarters in that year as there are fewer billable days in this quarter as a result of vacations and holidays. In addition, we generally perform services on a project basis. While we seek wherever possible to counterbalance periodic declines in revenues on completion of large projects with new arrangements to provide services to the same client

7


Table of Contents

or others, we may not be able to avoid declines in revenues when large projects are completed. Our inability to obtain sufficient new projects to counterbalance any decreases in work upon completion of large projects could adversely affect our revenues and results of operations.
Our software revenue may fluctuate quarterly, leading to volatility in the price of our stock.
     Our software revenue may fluctuate quarterly and be higher in the fourth quarter of a given year as procurement policies of our clients may result in higher technology spending towards the end of budget cycles. This seasonal trend may materially affect our quarter-to-quarter revenues, margins and operating results.
Our overall gross margin fluctuates quarterly based on our services and software revenue mix, which may cause our stock price to fluctuate.
     The gross margin on our services revenue is, in most instances, greater than the gross margin on our software revenue. As a result, our gross margin will be higher in quarters where our services revenue, as a percentage of total revenue, has increased, and will be lower in quarters where our software revenue, as a percentage of total revenue, has increased. In addition, gross margin on software revenue may fluctuate as a result of variances in gross margin on individual software products. Our stock price may be negatively affected in quarters in which our gross margin decreases.
Our services gross margins are subject to fluctuations as a result of variances in utilization rates and billing rates.
     Our services gross margins are affected by trends in the utilization rate of our professionals, defined as the percentage of our professionals’ time billed to customers divided by the total available hours in a period, and in the billing rates we charge our clients. Our operating expenses, including employee salaries, rent and administrative expenses are relatively fixed and cannot be reduced on short notice to compensate for unanticipated variations in the number or size of projects in process. If a project ends earlier than scheduled, we may need to redeploy our project personnel. Any resulting non-billable time may adversely affect our gross margins.
     The average billing rates for our services may decline due to rate pressures from significant customers and other market factors, including innovations and average billing rates charged by our competitors. Also, our average billing rates will decline if we acquire companies with lower average billing rates than ours. To sell our products and services at higher prices, we must continue to develop and introduce new services and products that incorporate new technologies or high-performance features. If we experience pricing pressures or fail to develop new services, our revenues and gross margins could decline, which could harm our business, financial condition and results of operations.
If we fail to complete fixed-fee contracts within budget and on time, our results of operations could be adversely affected.
     We perform a limited number of projects on a fixed-fee, turnkey basis, rather than on a time-and-materials basis. Under these contractual arrangements, we bear the risk of cost overruns, completion delays, wage inflation and other cost increases. If we fail to estimate accurately the resources and time required to complete a project or fail to complete our contractual obligations within the scheduled timeframe, our results of operations could be adversely affected. We cannot assure you that in the future we will not price these contracts inappropriately, which may result in losses.

Table of Contents

We may not be able to maintain our level of profitability.
     Although we have been profitable for the past nine quarters, we may not be able to sustain or increase profitability on a quarterly or annual basis in the future. We cannot assure you of any operating results. In future quarters, our operating results may not meet public market analysts’ and investors’ expectations. If this occurs, the price of our common stock will likely fall.
If we do not effectively manage our growth, our results of operations and cash flows could be adversely affected.
     Our ability to operate profitably with positive cash flows depends largely on how effectively we manage our growth. In order to create the additional capacity necessary to accommodate the demand for our services, we may need to implement a variety of new and upgraded operational and financial systems, procedures and controls, open new offices or hire additional colleagues. Implementation of these new systems, procedures and controls may require substantial management efforts and our efforts to do so may not be successful. The opening of new offices or the hiring of additional colleagues may result in idle or underutilized capacity. We periodically assess the expected long-term capacity utilization of our offices and professionals. We may not be able to achieve or maintain optimal utilization of our offices and professionals. If demand for our services does not meet our expectations, our revenues and cash flows will not be sufficient to offset these expenses and our results of operations and cash flows could be adversely affected.
We have recorded deferred offering costs in connection with the conversion of our registration statement into a shelf registration statement, and our inability to net these costs against the proceeds of future offerings off of our shelf registration statement could result in a non-cash expense in our Statement of Operations in a future period.
     We initially filed a registration statement with the Securities and Exchange Commission on March 7, 2005 to register the offer and sale by the Company and certain selling stockholders of shares of our common stock. Due to overall market conditions during the second quarter, we converted our registration statement into a shelf registration statement to allow for offers and sales of common stock from time to time as market conditions permit. To date, we have recorded approximately $943,000 of deferred offering costs (approximately $579,000 after tax, if ever expensed) in connection with the offering and have classified these costs as prepaid expenses in other non-current assets on our balance sheet. If we sell shares of common stock off of our shelf registration statement, we will be allowed to net these accumulated deferred offering costs against the proceeds of the offering. If we do not raise funds through an equity offering off of the shelf registration statement or fail to maintain the effectiveness of the shelf registration statement, the currently capitalized deferred offering costs will be expensed. Such expense would be a non-cash accounting charge as substantially all of these expenses have already been paid.
The Public Company Accounting Oversight Board, or PCAOB, is conducting an annual inspection of our external auditors BDO Seidman LLP.
     The PCAOB is a new private agency established to oversee the auditors of publicly held companies. The PCAOB is conducting an annual inspection of BDO Seidman LLP (BDO), as they do with all other large public accounting firms that audit the financial statements of publicly held companies. The PCAOB is inspecting BDO’s audits of a number of BDO clients, including BDO’s audit of our financial statements for the year ended December 31, 2004. The PCAOB staff has told BDO they differ with our accounting for forfeitable shares of stock issued in connection with one of our acquisitions in 2004 and has referred this matter to its Board. We and BDO believe that our accounting for this acquisition is correct. If it were ultimately determined that different accounting

9


Table of Contents

should be used for this acquisition, we estimate the resulting accounting impact would be a non-cash expense of approximately $600,000 per year after taxes over a period of three years from the date of the acquisition and a reduction in the acquisition’s purchase price of $3.1 million reflected on our balance sheet as reductions in goodwill and stockholders’ equity as of the acquisition date. The PCAOB’s inspection of BDO is ongoing and there can be no assurance as to its final scope or completion.
We may be exposed to potential risks resulting from new requirements under Section 404 of the Sarbanes-Oxley Act of 2002.
     Pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, we will be required, beginning with our fiscal year ending December 31, 2005, to include in our annual report our assessment of the effectiveness of our internal control over financial reporting as of the end of fiscal 2005. Furthermore, our independent registered public accounting firm, BDO Seidman, LLP, will be required to attest to whether our assessment of the effectiveness of our internal control over financial reporting is fairly stated in all material respects and separately report on whether it believes we have maintained, in all material respects, effective internal control over financial reporting as of December 31, 2005. We have not yet completed our assessment of the effectiveness of our internal control over financial reporting. We expect to incur additional expenses and diversion of management’s time as a result of performing the system and process evaluation, testing and remediation required in order to comply with the management certification and auditor attestation requirements. If we fail to timely complete this assessment, or if our independent registered public accounting firm cannot timely attest to our assessment, we could be subject to regulatory sanctions and a loss of public confidence in our internal control. In addition, any failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm our operating results or cause us to fail to timely meet our regulatory reporting obligations.
Risks Relating to Ownership of Our Common Stock
The trading volume of our common stock has been limited and, as a result, our stock price may fluctuate widely.
     Our common stock is traded on the Nasdaq National Market under the symbol “PRFT.” Our common stock has experienced low trading activity and our stock price has been volatile. Our stock price may continue to fluctuate widely as a result of the limited trading volume, announcements of new services and products by us or our competitors, quarterly variations in operating results, the gain or loss of significant customers, changes in public market analysts’ estimates and market conditions for information technology consulting firms and other technology stocks in general.
     We periodically review and consider possible acquisitions of companies that we believe will contribute to our long-term objectives. In addition, depending on market conditions, liquidity requirements and other factors, from time to time we consider accessing the capital markets. These events may also affect the market price of our common stock.

10


Table of Contents

Our officers, directors, and 5% and greater stockholders own a large percentage of our voting securities and their interests may differ from other stockholders.
     Our executive officers, directors and existing 5% and greater stockholders beneficially own or control approximately 30% of the voting power of our common stock. This concentration of ownership of our common stock may make it difficult for our other stockholders to successfully approve or defeat matters that may be submitted for action by our stockholders. It may also have the effect of delaying, deterring or preventing a change in control of our company.
We may need additional capital in the future, which may not be available to us. The raising of any additional capital may dilute your ownership percentage in our stock.
     We intend to continue to make investments to support our business growth and may require additional funds to pursue business opportunities and respond to business challenges. Accordingly, we may need to engage in equity or debt financings to secure additional funds. If we raise additional funds through further issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debt financing secured by us in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. In addition, we may not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us, when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly limited.
It may be difficult for another company to acquire us, and this could depress our stock price.
     Provisions contained in our certificate of incorporation, bylaws and Delaware law could make it difficult for a third party to acquire us, even if doing so would be beneficial to our stockholders. Our certificate of incorporation and bylaws may discourage, delay or prevent a merger or acquisition that a stockholder may consider favorable by authorizing the issuance of “blank check” preferred stock. In addition, provisions of the Delaware General Corporation Law also restrict some business combinations with interested stockholders. These provisions are intended to encourage potential acquirers to negotiate with us and allow the board of directors the opportunity to consider alternative proposals in the interest of maximizing stockholder value. However, these provisions may also discourage acquisition proposals or delay or prevent a change in control, which could harm our stock price.
     In addition, under our agreement with IBM, we have granted IBM a right of first offer and a right to terminate its agreement with us with respect to any transaction involving a change of control of us with a company that has a substantial portion of its business in the web application server product and services market, other than a systems integrator or professional services firm. As a result, a potential acquirer may be discouraged from making an offer to buy us.

USE OF PROCEEDS
     This prospectus related to the offer and sale from time to time of up to an aggregate of 483,896 shares of common stock for the account of the selling stockholders referred to in this prospectus. We will not receive any proceeds from the sale of any shares of common stock by the selling stockholders.
SELLING STOCKHOLDERS

     The following table sets forth information as of September 19, 2005 regarding the number of shares of common stock beneficially owned by the selling stockholders prior to the offering, the number of shares of common stock offered by the selling stockholders, and the number of shares of common stock that will be owned by the selling stockholders upon completion of the offering or offerings pursuant to this prospectus, assuming the selling stockholders sell all of the shares of common stock offered hereby. The percentage of shares beneficially owned prior to this offering in the following table is based on 22,914,702 shares of common stock outstanding as of September 19, 2005.
     Beneficial ownership is determined under the rules of the Securities and Exchange Commission. These rules deem common stock subject to options currently exercisable, or exercisable within 60 days, to be outstanding for purposes of computing the percentage ownership of the person holding the options or of a group of which the person is a member, but they do not deem such stock to be outstanding for purposes of computing the percentage ownership of any other person or group. To our knowledge, except under applicable community property laws, or as otherwise indicated, each person named in the table has sole voting and sole investment control with regard to all shares beneficially owned by such person.

     On June 26, 2002, Perficient entered into a Convertible Preferred Stock Purchase Agreement with 2M Technology Ventures, L.P., or 2M, pursuant to which 2M purchased 1,111,000 shares of Series B Preferred Stock for a purchase price of $0.900090009 per share. Pursuant to the Certificate of Designation, Rights and Preferences of the Series B Preferred Stock, on November 10, 2003, all then outstanding shares of Series B Preferred Stock automatically converted into shares of common stock. In connection with its purchase of Series B Preferred Stock, 2M also received a warrant to purchase up to 555,500 shares of common stock. 2M exercised this warrant on February 3, 2004 and March 29, 2004. We received proceeds of $1,100,000 as a result of the exercise of this warrant. We have registered 2,166,500 shares of our common stock, pursuant to a Registration Statement on Form S-3 (File No. 333-100490), for resale by 2M of the shares issued upon conversion of the shares of Series B Preferred Stock purchased from us, shares issued upon exercise of the warrant, and shares acquired upon purchase from certain of our stockholders in a private transaction.
