INNERWORKINGS, INC.

Our Company

We are a leading provider of print procurement solutions to corporate clients in the United States. Utilizing our proprietary technology and database, as well as our extensive domain expertise, we create a competitive bid process to procure, purchase and deliver printed products as part of a comprehensive outsourced enterprise solution and in individual transactions. Our technology is designed to capitalize on excess manufacturing capacity and other inefficiencies in the traditional print supply chain to obtain favorable pricing and to deliver high-quality products and services for our clients.

Our proprietary software applications and database, PPM4™, create a fully-integrated solution that stores, analyzes and tracks the production capabilities of our supplier network, as well as quote and price data for each bid we receive and print job we execute. As a result, we believe PPM4™ contains one of the largest independent repositories of equipment profiles and price data for print suppliers in the United States. We leverage our technology to match each print job with the supplier that is optimally suited to meet the client’s needs at a highly competitive price. Our procurement managers use PPM4™ to manage the print procurement process from end-to-end.

Through our network of over 2,700 suppliers, we offer a full range of print, fulfillment and logistics services that allows us to procure printed products on virtually any substrate. The breadth of our product offerings and services and the depth of our supplier network enable us to fulfill up to 100% of the print procurement needs of our clients. By leveraging our technology platform, our clients are able to reduce overhead costs, redeploy internal resources and obtain favorable pricing and service terms. In addition, our ability to track individual transactions and provide customized reports detailing print procurement activity on an enterprise-wide basis provides our clients with greater visibility and control of their print expenditures.

We generate revenue by procuring and purchasing printed products from our suppliers and selling those products to our clients. We procure printed products for clients across a wide range of industries, such as advertising, consumer products, publishing and retail. Our clients fall into two categories, enterprise and transactional. We enter into arrangements with our enterprise clients to provide some, or substantially all, of their printed products, typically on a recurring basis. We provide printed products to our transactional clients on an order-by-order basis. For the year ended December 31, 2005, enterprise and transactional clients accounted for 69% and 31% of our revenue, respectively.

We were formed in 2001 and commenced operations in 2002. From our inception through December 31, 2005, we served over 1,100 clients, received approximately 96,000 bids and executed approximately 26,000 print jobs through over 1,100 suppliers. We have increased our revenue from $5.0 million in 2002 to $76.9 million in 2005, representing a compound annual growth rate of 148%. In 2005, our revenue was $76.9 million, compared to $38.9 million in 2004. For the three months ended March 31, 2006, our revenue was $22.4 million, compared to $12.4 million for the three months ended March 31, 2005.

Our Industry

Our business of providing print procurement solutions intersects two large and growing industries, commercial printing and business process outsourcing, or BPO. Total shipments in the worldwide commercial print industry were projected to be approximately $367 billion in 2005 and are expected to increase by an average of $8 billion per year through 2009, according to a 2005 Datamonitor global commercial printing industry profile. To become more competitive, many businesses seek to focus on core competencies and outsource non-core business functions, such as print procurement. According to a 2005 IDC global BPO forecast, the worldwide market for BPO is estimated to grow from $422 billion in 2005 to $641 billion in 2009, representing a compound annual growth rate of 11%.

In addition, the U.S. print industry is highly fragmented, with an estimated 39,300 printing plants. In 2005, the ten largest commercial print companies accounted for only approximately 16% of the total domestic print market. The traditional process of designing, procuring and producing a print order requires extensive collaboration by printers, designers, brokers and other middlemen and is often highly inefficient for the customer, who typically pays a mark-up at each intermediate stage of the supply chain. Print procurement is often dispersed across several areas of a business enterprise, including sales, marketing, communications and finance. Consolidating all print activities across the organization represents an opportunity to reduce total print expenditure and decrease the number of vendors in the print supply chain. Applying software and database technology to manage the print procurement process also provides for enhanced tracking and auditing capabilities.

In recent years, the print industry has been impacted by developments in technology, including enhanced output capacity of printing presses and increased utilization of Internet-based communications and digital printing. These developments have lowered barriers to entry and reduced the utilization of printing presses. As a result, the print industry has historically experienced significant excess manufacturing capacity and the market for printed products has become increasingly commoditized.

Our Competitive Strengths

We believe a number of important competitive strengths will continue to drive our success in the future, including:

Disruptive business solution.    Our fully-integrated print procurement solution disrupts the traditional print supply chain by aggregating the collective print demand of our clients and greatly increasing the number of suppliers that can efficiently bid for our clients’ print jobs. Our print procurement costs are often 30 to 50% less than the print expenditures historically incurred by our clients, and we believe that we offer a compelling value proposition to our clients by passing on to them a considerable portion of such cost savings. In addition, our solution reduces the amount of internal resources our clients must dedicate to print procurement, accelerates the print procurement process and consistently delivers a high-quality product. We believe that our business model, which is unencumbered by commercial print production assets, offers the first enterprise solution capable of meeting the entire print procurement needs of corporate clients.

Proprietary software and database.    PPM4™ is a fully-integrated proprietary software solution that allows us to match each print job with the supplier in our network that is optimally suited to produce the job at a highly competitive price. Our technology also enables us to efficiently manage critical aspects of the print procurement process, including gathering job specifications, identifying suppliers, establishing pricing, managing print production and purchasing and coordinating delivery of the finished product.

We believe our proprietary database contains one of the largest independent repositories of equipment profiles and price data for print suppliers in the United States. This data provides us with valuable insight into how excess

2

manufacturing capacity and other industry factors impact the pricing of printed products, and enhances our ability to capitalize on those trends to our clients’ advantage. Our database expands with each job we quote and becomes more difficult to replicate, which we believe increases our competitive advantage.

Extensive and diverse supplier network.    The more than 2,700 suppliers in our network, which produced more than $50 billion of printed products in 2005, have been selected from among thousands of potential suppliers worldwide based on their ability to effectively serve our clients on the basis of price and service. Through these suppliers, we offer a full range of print, fulfillment and logistics services that allows us to procure printed products on virtually any substrate, including books, magazines, catalogues, direct mail, point-of-purchase displays, commercial print, packaging, labels and promotional products. By leveraging our access to a full range of print and print-related services, we are able to provide a complete and cost-effective outsourced solution for our clients.

Deep domain knowledge and procurement management expertise.    Effective management of the outsourced printing procurement process requires highly experienced and dedicated personnel to work closely with both clients and print suppliers. Our teams of account executives and procurement managers ensure high levels of execution and the on-time delivery of a quality product, while delivering domain expertise that spans advertising, consumer products, manufacturing, publishing, retail and other print-related industries. As of December 31, 2005, we employed over 80 account executives, who average 17 years of experience in the printing industry, and over 50 procurement managers, who average 13 years of experience in the printing industry.

Scalable business model with significant operating leverage.    Our technology solution can support a significant increase in the number of clients we serve and jobs we process without significant capital investment. In addition, our extensive supplier network provides access to a vast supply of manufacturing capacity without requiring any capital expense. Because we do not own commercial print production assets, the primary incremental operating cost of growing our business is hiring additional account executives who market and sell our services, and procurement managers who manage the print procurement process. As a result, our revenue growth has significantly outpaced the increase in our operating expenses. Our revenue increased from $5.0 million in 2002 to $76.9 million in 2005, while our operating expenses as a percentage of revenue, which exclude cost of goods sold, decreased from 23.2% in 2002 to 14.3% in 2005.

Experienced management team.    We have a highly experienced management team with extensive industry knowledge. Our Chief Executive Officer, Steven Zuccarini, is the former president of the Catalog & Retail and the Global Solutions business units of North America’s largest print company, R.R. Donnelley & Sons Company, where he was responsible for providing enterprise solutions to its largest clients. Our non-executive Chairman, John Walter, is the former Chairman and Chief Executive Officer of R.R. Donnelley.

Our Growth Strategy

We intend to become the preeminent provider of print procurement solutions on a global basis. The key elements of our growth strategy include:

Expand our base of enterprise clients.    We are focused on continuing to increase our business with clients using our technology enabled enterprise solution. During 2005, we entered into contracts with 23 enterprise clients, including 17 new clients and six clients that we initially serviced on a transactional basis. We seek to attract new enterprise clients by targeting companies which have substantial and recurring print requirements. We also seek to transition transactional clients to our enterprise solution in order to capture a greater portion of their recurring print expenditures and become more fully integrated into their business infrastructure. This strategy has been highly successful as 25 of our 76 enterprise clients as of March 31, 2006 began as transactional accounts.

3

Expand our base of transactional clients.    As a significant portion of our new transactional business results from our recruitment of sales executives, we intend to continue to hire account executives, or acquire groups of them, with established client relationships. We believe our business model is extremely attractive to these executives, as it enables sales professionals to leverage our technology and supplier network to market a broader range of products and services to their clients than were available with their previous employers. As these executives are hired, we expect to expand our base of transactional clients, thereby expanding our pipeline of clients to which we can market our enterprise solution.

Further penetrate our established customer base.    We believe our established customer base presents a substantial opportunity for growth. Our ability to deliver a full range of printed products at competitive prices and procure up to 100% of the print requirements of our clients allows us to capitalize on our established client relationships to increase our sales. As we further develop our relationships with clients, we seek to manage more of their total print expenditures over time. For example, we estimate that during 2005 sales to our ten largest enterprise clients accounted for less than 25% of their total print expenditures.

Broaden geographic presence.    We believe the opportunity exists to expand our business into new geographic markets. Our headquarters are located in Chicago, and as of December 31, 2005 approximately 66% of our clients were located in Illinois. Our objective is to increase our sales in other major print markets in the United States, such as Boston, Los Angeles, Minneapolis, New York and San Francisco. We intend to hire or acquire more account executives within close proximity to these large markets, which accounted for, in aggregate, $18.4 billion of print expenditures in 2005, according to PIA/GATF. In addition, given that the print industry is a global business, over time we intend to evaluate opportunities to access attractive markets outside the United States. For example, in March 2006 we entered into a strategic agreement to grant SNP Corporation Ltd. a non-exclusive, non-transferable license to use certain non-core applications of our software in China, Singapore and Hong Kong.

Recent Development

Series E Investment. In January 2006, we issued 10,167,730 Series E preferred shares, or approximately 25% of our equity interests on a fully-diluted basis, to New Enterprise Associates 11, Limited Partnership, NEA Ventures 2005, Limited Partnership and Printworks Series E, LLC in exchange for $50 million in cash, or $4.92 per share. We retained $10 million of these proceeds for working capital and general corporate purposes. We used $40 million of these proceeds to redeem Class A common shares held by our existing stockholders on a pro rata basis at a purchase price of $4.92 per share.

Risk Factors

Investing in our common stock involves risks. You should carefully read the section entitled “Risk Factors” beginning on page 9 for an explanation of these risks before investing in our common stock. In particular, the following considerations, among others, may offset our competitive strengths or have a negative effect on our growth strategy, which could cause a decrease in the price of our common stock and result in a loss of all or a portion of your investment:

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the following risks and other information in this prospectus before you decide to buy our common stock. Our business, financial condition or operating results may suffer if any of the following risks is realized. Additional risks and uncertainties not currently known to us may also adversely affect our business, financial condition or operating results. If any of these risks or uncertainties occurs, the trading price of our common stock could decline and you might lose all or part of your investment.

Risks Related to Our Business

Our limited operating history makes it difficult to evaluate our business, prospects and future financial performance.

We formed our business in September 2001 and have a limited operating history, which makes evaluating our current business and prospects difficult. The revenue and income potential of our business is uncertain, which makes it difficult to predict accurately our future financial performance. We may face periods where our financial performance falls below investor expectations. As a result, the price of our common stock may decline.

Competition could substantially impair our business and our operating results.

We operate in the print industry and several print-related industries, including paper and pulp, graphics art and pre-press and fulfillment and logistics. Competition in these industries is intense. Our primary competitors are printers that employ traditional methods of marketing and selling their printed materials. Many of these printers, such as Banta, Quad/Graphics, Quebecor and R.R. Donnelley have larger client bases and significantly more resources than we do. Print buyers may prefer to utilize the traditional services offered by the printers with whom we compete. Alternatively, some of these printers may elect to offer outsourced print procurement services or enterprise software applications, and their well-established client relationships, industry knowledge, brand recognition, financial and marketing capabilities, technical resources and pricing flexibility may provide them with a competitive advantage over us.

We also compete with a number of print suppliers, distributors and brokers. Several of these competitors, such as Cirqit, Workflow/Relizon and Newline/Noosh offer outsourced print procurement services or enterprise software applications for the print industry. These competitors, or new competitors that enter the market, may also offer print procurement services similar to and competitive with or superior to our current or proposed offerings and achieve greater market acceptance. In addition, a software solution and database similar to PPM4^TM could be created over time by a competitor with sufficient financial resources and comparable experience in the print industry. If our competitors are able to offer comparable services, we could lose clients, and our market share could decline.

Our competitors may also establish cooperative relationships to increase their ability to address client needs. Increased competition may lead to revenue reductions, reduced gross margins or a loss of market share, any one of which could harm our business.

If our services do not achieve widespread commercial acceptance, our business will suffer.

Most companies currently coordinate the procurement and management of their print orders with their own employees using a combination of telephone, facsimile, e-mail and the Internet. Growth in the demand for our services depends on the adoption of our outsourcing model for print procurement services. We may not be able to persuade prospective clients to change their traditional print management processes. Our business could suffer if our services are not accepted or are not perceived by the marketplace to be effective or valuable.

If our suppliers do not meet our needs or expectations, or those of our clients, our business would suffer.

The success of our business depends to a large extent on our relationships with our clients and our reputation for high quality printed products and print procurement services. We do not own printing presses or other printing equipment. Instead, we rely on third-party suppliers to deliver the printed products and services that we provide to our clients. As a result, we do not directly control the manufacturing of the products or the services provided by our suppliers. If our suppliers do not meet our needs or expectations, or those of our clients, our professional reputation may be damaged, our business would be harmed and we could be subject to legal liability.

A decrease in the number of our suppliers could adversely affect our business.

In 2005, our top 10 suppliers accounted for approximately 40% of the products we sold, and our top three suppliers accounted for approximately 21% of the products we sold. We expect to continue to rely on these suppliers to fulfill a substantial portion of our print orders in the future. These suppliers are not contractually required to continue to accept orders from us. If production capacity at a significant number of these suppliers becomes unavailable, we will be required to use fewer suppliers, which could significantly limit our ability to serve our clients on competitive terms. In addition, we rely on price bids provided by our suppliers to populate our database. If the number of our suppliers decreases significantly, we will not be able to obtain sufficient pricing information for PPM4 ^TM, which could affect our ability to obtain favorable pricing for our clients.

If we are unable to expand the number of our account executives, or if a significant number of our account executives leave InnerWorkings, our ability to increase our revenues could be negatively impacted.

Our ability to expand our business will depend largely on our ability to attract additional account executives with established client relationships. Competition for qualified account executives can be intense and we may be unable to hire such persons. Any difficulties we experience in expanding the number of our account executives could have a negative impact on our ability to expand our client base, increase our revenue and continue our growth.

In addition, we must retain our current account executives and properly incentivize them to obtain new clients and maintain existing client relationships. If a significant number of our account executives leave InnerWorkings and take their clients with them, our revenue could be negatively impacted. We have entered into non-compete agreements with our account executives to mitigate this risk, but we may need to litigate to enforce our rights under these agreements, which could be time-consuming, expensive and ineffective. A significant increase in the turnover rate among our current account executives could also increase our recruiting costs and decrease our operating efficiency and productivity, which could lead to a decline in the demand for our services.

If we are unable to expand our enterprise client base, our revenue growth rate may be negatively impacted.

As part of our growth strategy, we seek to attract new enterprise clients and migrate our transactional client relationships into enterprise engagements under long-term contracts. If we are unable to attract new enterprise clients or expand our relationships with our existing transactional clients, our ability to expand our business will be hindered.

Many of our clients may terminate their relationship with us on short notice and with no penalties or limited penalties.

Our transactional clients, which accounted for approximately 31% and 50% of our revenue in 2005 and 2004, respectively, typically use our services on an order-by-order basis rather than under long-term contracts. These clients have no obligation to continue using our services and may stop purchasing from us at any time. We have entered into contracts with our enterprise clients, which accounted for approximately 69% and 50% of our

10

revenue in 2005 and 2004, respectively, that generally have an open-ended duration. Most of these contracts, however, do not impose minimum purchase or volume requirements, and typically permit the clients to terminate our engagements on 90 or 180 days’ notice with limited or no penalties.

The volume and type of services we provide our clients may vary from year to year and could be reduced if the client were to change its outsourcing or print procurement strategy. If a significant number of our transactional or enterprise clients elect to terminate or not to renew their engagements with us, or if the volume of their print orders decreases, our business, operating results and financial condition could suffer.

A significant portion of our revenue is derived from a relatively limited number of large clients and any loss of, or decrease in sales to, these clients could harm our results of operations.

A significant portion of our revenue is derived from a relatively limited number of large clients. Revenue from our top ten clients accounted for 46% and 43% of our revenue during the year ended December 31, 2005 and 2004, respectively. Our largest customer accounted for 16% of our revenue in 2005. We are likely to continue to experience a similar degree of customer concentration, particularly if we are successful in attracting large enterprise clients. We cannot assure you that there will not be a loss or reduction in business from one or more of our large clients. In addition, we cannot assure you that revenue from these clients, either individually or as a group, will reach or exceed historical levels in any future period. The loss or significant reduction of business from our major clients would adversely affect our results of operations.

We may not be able to develop or implement new systems, procedures and controls that are required to support the anticipated growth in our operations.

Our revenues increased from $5.0 million in 2002 to $76.9 million in 2005, representing a compound annual growth rate of 148%. Between January 1, 2002 and December 31, 2005, the number of our employees and independent contractors increased from 21 to 154. Continued growth could place a significant strain on our ability to:

· recruit, motivate and retain qualified account executives, procurement managers and management personnel;

· preserve our culture, values and entrepreneurial environment;

· develop and improve our internal administrative infrastructure and execution standards; and

· maintain high levels of client satisfaction.

To manage our growth, we must implement and maintain proper operational and financial controls and systems. Further, we will need to manage our relationships with various clients and suppliers. We cannot give any assurance that we will be able to develop and implement, on a timely basis, the systems, procedures and controls required to support the growth in our operations or effectively manage our relationships with various clients and suppliers. If we are unable to manage our growth, our business, operating results and financial condition could be adversely affected.

A decrease in levels of excess capacity in the U.S. commercial print industry could have an adverse impact on our business.

We believe that for the past several years, the U.S. commercial print industry has experienced significant levels of excess capacity. Our business seeks to capitalize on imbalances between supply and demand in the print industry by obtaining favorable pricing terms from suppliers in our network through a competitive bid process. Reduced excess capacity in the print industry generally and in our supplier network specifically could have an adverse impact on our ability to execute our business strategy and on our business results and growth prospects.

11

Our inability to protect our intellectual property rights may impair our competitive position.

If we fail to protect our intellectual property rights adequately, our competitors could replicate our proprietary technology in order to offer similar services and harm our competitive position. We rely on a combination of trademark and trade secret laws and confidentiality and nondisclosure agreements to protect our proprietary technology. We cannot be certain that the steps we have taken to protect our intellectual property rights will be adequate or that third parties will not infringe or misappropriate our rights or imitate or duplicate our services or methodologies, including PPM4™. We may need to litigate to enforce our intellectual property rights or determine the validity and scope of the rights of others. Any such litigation could be time-consuming and costly.

If we are unable to maintain PPM4™ , demand for our services and our revenues could decrease.

We rely heavily on PPM4™ to procure printed products for our clients. To keep pace with changing technologies and client demands, we must correctly interpret and address market trends and enhance the features and functionality of our technology in response to these trends, which may lead to significant research and development costs. We may be unable to accurately determine the needs of print buyers, the trends in the print industry or to design and implement the appropriate features and functionality of our technology in a timely and cost-effective manner, which could result in decreased demand for our services and a corresponding decrease in our revenue.

In addition, we must protect our systems against physical damage from fire, earthquakes, power loss, telecommunications failures, computer viruses, hacker attacks, physical break-ins and similar events. Any software or hardware damage or failure that causes interruption or an increase in response time of PPM4™ could reduce client satisfaction and decrease usage of our services.

If the key members of our management team do not remain with us in the future, our business, operating results and financial condition could be adversely affected.

Our future success will depend to a significant extent on the continued services of Steven Zuccarini, our Chief Executive Officer, Nicholas Galassi, our Chief Financial Officer, Scott Frisoni, our Executive Vice President of Sales, Eric Belcher, our Executive Vice President of Operations, and Neil Graver, our Chief Technology Officer. The loss of the services of any of these or other individuals could adversely affect our business, operating results and financial condition and could divert other senior management time in searching for their replacements.

Our management team has limited experience managing a public company, and regulatory compliance may divert its attention from the day-to-day management of our business.

The individuals who now constitute our management team have limited experience managing a publicly-traded company and limited experience complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage our transition into a public company that will be subject to significant regulatory oversight and reporting obligations under federal securities laws. In particular, these new obligations will require substantial attention from our senior management and divert its attention away from the day-to-day management of our business, which could materially and adversely impact our business operations.

Because many of the members of our management team have been employed with us for a short period of time, we cannot be certain that they will be able to manage our business successfully.

We are dependent on our management team for our business to be successful. Because of our limited operating history, many of our key management personnel have been employed by us for less than two years. Therefore, we cannot be certain that we will be able to allocate responsibilities appropriately and that the new members of our management team will succeed in their roles. Our inability to integrate members of our current

12

management team with our business model would make it difficult for us to manage our business successfully and to pursue our growth strategy.

Our business is subject to seasonal sales fluctuations, which could result in volatility or have an adverse effect on the market price of our common stock.

Our business is subject to some degree of sales seasonality. Historically, the percentage of our annual revenue earned during the third and fourth fiscal quarters has been higher due, in part, to a greater number of print orders in anticipation of the year-end holiday season. If our business continues to experience seasonality, we may incur significant additional expenses during our third and fourth quarters, including additional staffing expenses. Consequently, if we were to experience lower than expected revenue during any future third or fourth quarter, whether from a general decline in economic conditions or other factors beyond our control, our expenses may not be offset, which would have a disproportionate impact on our operating results and financial condition for that year.

Price fluctuations in raw materials costs could adversely affect the margins on our print orders.

The print industry relies on a constant supply of various raw materials, including paper and ink. Prices within the print industry are directly affected by the cost of paper, which is purchased in a price sensitive market that has historically exhibited price and demand cyclicality. Prices are also affected by the cost of ink. Our profit margin and profitability is largely a function of the rates that our suppliers charge us compared to the rates that we charge our clients. If our suppliers increase the price of our print orders, and we are not able to find suitable or alternative suppliers, our profit margin may decline.

If any of our products cause damages or injuries, we may experience product liability claims.

Clients and third parties who claim to suffer damages or an injury caused by our products may bring lawsuits against us. Defending lawsuits arising out of any of the products we provide to our clients could be costly and absorb substantial amounts of management attention, which could adversely affect our financial performance. A significant product liability judgment against us could harm our reputation and business.

If any of our key clients fail to pay for our services, our profitability would be negatively impacted.

We take full title and risk of loss for the printed products we procure from our suppliers. Our obligation to pay our suppliers is not contingent upon receipt of payment from our clients. In 2004 and 2005, our revenue was $38.9 million and $76.9 million, respectively, and our top 10 clients accounted for 43% and 46%, respectively, of such revenue in the aggregate. If any of our key clients fail to pay for our services, our profitability would be negatively impacted.

We may not be able to identify suitable acquisition candidates, effectively integrate newly acquired businesses or achieve expected profitability from acquisitions.

Part of our growth strategy is to increase our revenue and the markets that we serve through the acquisition of additional businesses. We are actively considering certain acquisitions and will likely consider others. There can be no assurance that suitable candidates for acquisitions can be identified or, if suitable candidates are identified, that acquisitions can be completed on acceptable terms, if at all. Even if suitable candidates are identified, any future acquisitions may entail a number of risks that could adversely affect our business and the market price of our common stock, including the integration of the acquired operations, diversion of management’s attention, risks of entering markets in which we have limited experience, adverse short-term effects on our reported operating results, the potential loss of key employees of acquired businesses and risks associated with unanticipated liabilities.

We may use common stock to pay for acquisitions. If the owners of potential acquisition candidates are not willing to receive common stock in exchange for their businesses, our acquisition prospects could be limited.

13

Future acquisitions could also result in accounting charges, potentially dilutive issuances of equity securities and increased debt and contingent liabilities, including liabilities related to unknown or undisclosed circumstances, any of which could have a material adverse effect on our business and the market price of our common stock.

We will incur increased costs as a result of being a public company.

We will face increased legal, accounting, administrative and other costs and expenses as a public company that we do not incur as a private company. The Sarbanes-Oxley Act of 2002, including the requirements of Section 404, as well as new rules and regulations subsequently implemented by the Securities and Exchange Commission (the SEC), the Public Company Accounting Oversight Board and the Nasdaq National Market, imposes additional reporting and other obligations on public companies. We expect that compliance with these public company requirements will increase our costs and make some activities more time-consuming. A number of those requirements will require us to carry out activities we have not done previously. For example, we will create new board committees and adopt new internal controls and disclosure controls and procedures. In addition, we will incur additional expenses associated with our SEC reporting requirements. For example, under Section 404 of the Sarbanes-Oxley Act, for our annual report on Form 10-K for our fiscal year ending December 31, 2007 we will need to document and test our internal control procedures, our management will need to assess and report on our internal control over financial reporting and our independent accountants will need to issue an opinion on that assessment and the effectiveness of those controls. Furthermore, if we identify any issues in complying with those requirements (for example, if we or our accountants identified a material weakness or significant deficiency in our internal control over financial reporting), we could incur additional costs rectifying those issues, and the existence of those issues could adversely affect us, our reputation or investor perceptions of us. We also expect that it will be difficult and expensive to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantially higher costs to obtain the same or similar coverage. As a result, it may be more difficult for us to attract and retain qualified persons to serve on our board of directors or as executive officers. Advocacy efforts by stockholders and third parties may also prompt even more changes in governance and reporting requirements. We expect that the additional reporting and other obligations imposed on us by these rules and regulations will increase our legal and financial compliance costs and the costs of our related legal, accounting and administrative activities by approximately $1.3 million per year. These increased costs will require us to divert a significant amount of money that we could otherwise use to expand our business and achieve our strategic objectives.

Our ability to raise capital in the future may be limited, and our failure to raise capital when needed could prevent us from growing.

We may in the future be required to raise capital through public or private financing or other arrangements. Such financing may not be available on acceptable terms, or at all, and our failure to raise capital when needed could harm our business. Additional equity financing may be dilutive to the holders of our common stock, and debt financing, if available, may involve restrictive covenants and could reduce our profitability. If we cannot raise funds on acceptable terms, we may not be able to grow our business or respond to competitive pressures.

A significant or prolonged economic downturn, or a dramatic decline in the demand for printed products, could adversely affect our revenues and results of operations.

Our results of operations are affected directly by the level of business activity of our clients, which in turn is affected by the level of economic activity and cyclicality in the industries and markets that they serve. Certain of our products are sold to industries, including the advertising industry, that experience significant fluctuations in demand based on general economic conditions, cyclicality and other factors beyond our control. An economic stagnation or downturn could result in a reduction of the marketing budgets of our clients or a decrease in the number of print jobs that our clients order from us. Reduced demand from one of these industries or markets could adversely affect our revenues, operating income and profitability.

Risks Related to this Offering and Ownership of Our Common Stock

Our stock price may be volatile, and you may not be able to resell your shares at or above the initial public offering price.

Prior to this offering, there has been no public market for shares of our common stock. An active public trading market for our common stock may not develop or, if it develops, may not be maintained after this offering, and the market price could fall below the initial public offering price. If no trading market develops, securities analysts may not initiate or maintain research coverage of our company, which could further depress the market for our common stock. Some of the factors that may cause the market price of our common stock to fluctuate include:

Ÿ fluctuations in our quarterly financial results or the quarterly financial results of companies perceived to be similar to us;

Ÿ changes in market valuations of similar companies;

Ÿ success of competitive products or services;

Ÿ changes in our capital structure, such as future issuances of debt or equity securities;

Ÿ announcements by us, our competitors, our clients or our suppliers of significant products or services, contracts, acquisitions or strategic alliances;

Ÿ regulatory developments in the United States or foreign countries;

Ÿ litigation involving our company, our general industry or both;

Ÿ additions or departures of key personnel;

Ÿ investors’ general perception of us; and

Ÿ changes in general economic, industry and market conditions.

In addition, if the stock market in general experiences a loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our business, financial condition or results of operations. If any of the foregoing occurs, it could cause our stock price to fall and may expose us to class action lawsuits that, even if unsuccessful, could be costly to defend and a distraction to management. As a result, you could lose all or part of your investment. Our company, the selling stockholders and the representatives of the underwriters have negotiated to determine the initial public offering price. The initial public offering price may be higher than the trading price of our common stock following this offering.

If equity research analysts do not publish research or reports about our business or if they issue unfavorable commentary or downgrade our common stock, the price of our common stock could decline.

The trading market for our common stock will rely in part on the research and reports that equity research analysts publish about us and our business. We do not control these analysts. The price of our stock could decline if one or more equity analysts downgrade our stock or if those analysts issue other unfavorable commentary or cease publishing reports about us or our business.

Our quarterly results are difficult to predict and may vary from quarter to quarter, which may result in our failure to meet the expectations of investors and increased volatility of our stock price.

The continued use of our services by our clients depends, in part, on the business activity of our clients and our ability to meet their cost saving needs, as well as their own changing business conditions. The time between our payment to the supplier of a print job and our receipt of payment from our clients varies with each print job and client. In addition, a significant percentage of our revenue is subject to the discretion of our enterprise and transactional clients, who may stop using our services at any time, subject, in the case of most of our enterprise clients, to advance notice requirements. Therefore, the number, size and profitability of print jobs may vary

15

significantly from quarter to quarter. As a result, our quarterly operating results are difficult to predict and may fall below the expectations of current or potential investors in some future quarters, which could lead to a significant decline in the market price of our stock. This may lead to volatility in our stock price. The factors that are likely to cause these variations include:

Ÿ the demand for our print procurement solution;

Ÿ the use of outsourced enterprise solutions;

Ÿ clients’ business decisions regarding the quantities of printed products they purchase;

Ÿ the number, timing and profitability of our print jobs, unanticipated contract terminations or print job postponements;

Ÿ new product introductions and enhancements by our competitors;

Ÿ changes in our pricing policies;

Ÿ our ability to manage costs, including personnel costs; and

Ÿ costs related to possible acquisitions of other businesses.

Because a limited number of stockholders control the majority of the voting power of our common stock, investors in this offering will not be able to determine the outcome of stockholder votes.

Upon completion of this offering, Orange Media, LLC, an entity owned by Elizabeth Kramer Lefkofsky, who is the wife of Eric P. Lefkofsky, Richard A. Heise, Jr., and Incorp, LLC, an entity controlled by Orange Media and Mr. Heise, will beneficially own and have the ability to exercise voting control over, in the aggregate, approximately     % of our outstanding common stock. In addition, New Enterprise Associates 11, Limited Partnership and NEA Ventures 2005, Limited Partnership will beneficially own, and have the ability to exercise voting control over, in the aggregate, approximately     % of our outstanding common stock. As a result, these stockholders will be able to exercise significant control over all matters requiring stockholder approval, including the election of directors, any amendments to our certificate of incorporation and significant corporate transactions. These stockholders may exercise this control even if they are opposed by our other stockholders. Without the consent of these stockholders, we could be delayed or prevented from entering into transactions (including the acquisition of our company by third parties) that may be viewed as beneficial to us or our other stockholders. In addition, this significant concentration of stock ownership may adversely affect the trading price of our common stock if investors perceive disadvantages in owning stock in a company with controlling stockholders.

The future sale of our common stock could negatively affect our stock price after this offering.

After this offering, we will have              shares of common stock outstanding,              of which will be available for immediate public sale. The remaining              shares of common stock outstanding after this offering, including an aggregate of              shares beneficially owned by Orange Media, LLC, Richard A. Heise, Jr., New Enterprise Associates 11, Limited Partnership and NEA Ventures 2005, Limited Partnership, will be available for sale, subject to volume and other limitations as applicable under the federal securities laws. Additional sales of our common stock in the public market after this offering, or the perception that these sales could occur, could cause the market price of our common stock to decline.

Our directors, executive officers and stockholders have agreed to enter into “lock up” agreements with the underwriters, in which they will agree to refrain from selling their shares for a period of 180 days after this offering. Approximately              of these shares will become available for sale 180 days after this offering upon the expiration of these agreements. Increased sales of our common stock in the market could exert significant downward pressure on our stock price. These sales also may make it more difficult for us to sell equity or equity-related securities in the future at a time and price we deem appropriate.

16

In addition, approximately              of our shares of common stock, including shares beneficially owned by Orange Media, LLC, Mr. Heise and New Enterprise Associates 11, Limited Partnership and NEA Ventures 2005, Limited Partnership, will be entitled to registration rights with respect to these shares after this offering. Such holders may require us to register the resale of all or substantially all of these shares upon demand. These holders include certain individuals and entities that will be selling shares of our common stock in this offering.

We will have broad discretion in using our net proceeds from this offering, and the benefits from our use of the proceeds may not meet investors’ expectations.

Our management will have broad discretion over the allocation of our net proceeds from this offering as well as over the timing of their expenditure without stockholder approval. We have not yet determined the specific amounts of the $     million of our net proceeds to be used to expand our sales force, to acquire or make strategic investments in complementary businesses and for working capital and other general corporate purposes. As a result, investors will be relying upon management’s judgment with only limited information about our specific intentions for the use of the balance of our net proceeds from this offering. Our failure to apply these proceeds effectively could cause our business to suffer.

Because our existing investors paid substantially less than the initial public offering price when they purchased their shares, new investors will incur immediate and substantial dilution in their investment.

Investors purchasing shares in this offering will incur immediate and substantial dilution in net tangible book value per share because the price that new investors pay will be substantially greater than the net tangible book value per share of the shares acquired. This dilution is due in large part to the fact that our existing investors paid substantially less than the initial public offering price when they purchased their shares. In addition, there will be options to purchase approximately              shares of common stock outstanding upon completion of this offering. To the extent such options are exercised in the future, there will be further dilution to new investors.

The initial public offering price for the shares sold in this offering was determined by negotiations among us, the selling stockholders and the representatives of the underwriters and may not be indicative of prices that will prevail in the trading market. See “Underwriting” for a discussion of the determination of the initial public offering price.

We do not currently intend to pay dividends, which may limit the return on your investment in us.

We currently intend to retain all available funds and any future earnings for use in the operation and expansion of our business and do not anticipate paying any cash dividends in the foreseeable future.

FORWARD-LOOKING STATEMENTS

Many of the statements included in this prospectus contain forward-looking statements and information relating to our company. We generally identify forward-looking statements by the use of terminology such as “may,” “will,” “could,” “should,” “potential,” “continue,” “expect,” “intend,” “plan,” “estimate,” “anticipate,” “believe,” or similar phrases or the negatives of such terms. We base these statements on our beliefs as well as assumptions we made using information currently available to us. Such statements are subject to risks, uncertainties and assumptions, including those identified in “Risk Factors,” as well as other matters not yet known to us or not currently considered material by us. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected. Given these risks and uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements, which speak only as of the date of this prospectus. Forward-looking statements do not guarantee future performance and should not be considered as statements of fact.

Factors that may cause actual results to differ from expected results include, among others:

Ÿ general economic conditions and a downturn in the printing and business process outsourcing industry;

Ÿ competition in our industry and innovation by our competitors;

Ÿ our failure to anticipate and adapt to future changes in our industry;

Ÿ uncertainty regarding our product and service innovations;

Ÿ our inability to successfully identify and manage our acquisitions or hire qualified account executives;

Ÿ adverse developments concerning our relationships with certain key clients or suppliers;

Ÿ our inability to adequately protect our intellectual property and litigation regarding intellectual property;

Ÿ the increased expenses and administrative workload associated with being a public company; and

Ÿ failure to maintain an effective system of internal controls necessary to accurately report our financial results and prevent fraud.

All future written and verbal forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. We undertake no obligation, and specifically decline any obligation, to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. In light of these risks, uncertainties and assumptions, the forward-looking events discussed in this prospectus might not occur.

See the section entitled “Risk Factors” for a more complete discussion of these risks and uncertainties and for other risks and uncertainties. These factors and the other risk factors described in this prospectus are not necessarily all of the important factors that could cause actual results to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could harm our results. Consequently, there can be no assurance that the actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, us.

18

USE OF PROCEEDS

We estimate that the net proceeds to us from the sale of the              shares of our common stock we are offering will be approximately $         million, assuming an initial public offering price of $         per share, the midpoint of the filing range set forth on the cover of this prospectus, and after deducting the underwriting discounts and estimated expenses payable by us. We will not receive any proceeds from the sale of shares of our common stock by the selling stockholders.

We intend to use our net proceeds from this offering primarily to expand our sales force, to acquire or make strategic investments in complementary businesses and for working capital and other general corporate purposes. As of the date of this prospectus, we have no binding commitment or agreement relating to any acquisition or investment. We have not yet determined the amount of our net proceeds to be used specifically for any of the foregoing purposes. Accordingly, management will have significant flexibility in applying our net proceeds of this offering. We also intend to use a portion of our net proceeds from this offering to repay all outstanding principal and accrued interest owed under our line of credit with JPMorgan Chase Bank, N.A. The amounts borrowed under our line of credit are due in full on June 30, 2006. As of March 31, 2006, the outstanding indebtedness under our line of credit was $2.2 million, which bears interest at the prime rate. We used the borrowings under our line of credit during 2005 for working capital and other general corporate purposes. In addition to the foregoing purposes, we intend to use approximately $7.0 million of our net proceeds from this offering to make required preference and accrued dividend payments to the holders of our Series B, D and E preferred shares. Pending their use, we intend to invest the balance of our net proceeds from this offering in short-term, investment grade interest-bearing instruments.

DIVIDEND POLICY

We currently do not intend to pay any dividends on our common stock after the completion of this offering. We intend to retain all available funds and any future earnings for use in the operation and expansion of our business. Any determination in the future to pay dividends will depend upon our financial condition, capital requirements, operating results and other factors deemed relevant by our board of directors, including any contractual or statutory restrictions on our ability to pay dividends.

DILUTION

If you invest in our common stock, your interest will be diluted immediately to the extent of the difference between the public offering price per share of our common stock and the pro forma net tangible book value per share of our common stock after this offering.

Our pro forma net tangible book value as of March 31, 2006 was approximately $         million, or $         per share of common stock. Pro forma net tangible book value per share represents the amount of our total tangible assets reduced by the amount of our total liabilities, divided by the number of shares of common stock outstanding on a pro forma basis after giving effect to the recapitalization of all outstanding shares of our capital stock into shares of our common stock and a             :                     stock split of our common stock to be effectuated immediately prior to the completion of this offering.

After giving effect to the sale of the              shares of common stock offered by us assuming an initial public offering price of $         per share, the midpoint of the filing range set forth on the cover of this prospectus, and after deducting the underwriting discounts and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value as of March 31, 2006 would have been approximately $         million, or $         per share. This represents an immediate increase in pro forma net tangible book value of $         per share to existing stockholders and an immediate dilution of $         per share to new investors. The following table illustrates this dilution:

Initial public offering price per share

Pro forma net tangible book value per share before this offering

Increase in pro forma net tangible book value per share attributable to this offering

Pro forma as adjusted net tangible book value per share after this offering

Dilution per share to new investors

We will not receive any proceeds from the sale of the              shares to be sold by the selling stockholders or the              shares that may be sold by the selling stockholders pursuant to the underwriters’ over-allotment option.

The following table sets forth on a pro forma as adjusted basis as of March 31, 2006:

• the number of shares of our common stock purchased by existing stockholders, the total consideration and the average price per share paid for those shares;

• the number of shares of our common stock purchased by new investors, the total consideration and the average price per share paid for those shares (assuming an initial public offering price of $         per share, the midpoint of the filing range set forth on the cover of this prospectus); and

• the percentage of shares purchased by existing stockholders and new investors and the percentage of consideration paid for those shares.

These pro forma numbers give effect to the recapitalization of all outstanding shares of our capital stock into shares of our common stock and a             :                     stock split of our common stock to be effectuated immediately prior to the completion of this offering.

	Total shares			Total consideration			Average price per share

The outstanding share information shown in the table above excludes:

•              shares of common stock issuable upon the exercise of outstanding stock options under our stock incentive plan at a weighted average exercise price of $     per share; and

•              shares of common stock available for future grants under our stock incentive plan as of the date of this prospectus.

To the extent that any of these options are exercised, your investment will be further diluted. In addition, we may grant more options in the future. If the underwriters exercise their over-allotment option in full, the following will occur:

• the pro forma as adjusted number of shares of our common stock held by existing stockholders will decrease to             , or approximately     % of the total number of pro forma as adjusted shares of our common stock outstanding after this offering; and

• the pro forma as adjusted number of shares of our common stock held by new investors will increase to             , or approximately     % of the total pro forma as adjusted shares of our common stock outstanding after this offering.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the consolidated financial statements and accompanying notes, which appear elsewhere in this prospectus. It contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those discussed below and elsewhere in this prospectus, particularly under the heading “Risk Factors.”

Overview

We are a leading provider of print procurement solutions to corporate clients in the United States. Utilizing our proprietary technology and database, as well as our extensive domain expertise, we create a competitive bid process to procure, purchase and deliver printed products as part of a comprehensive outsourced enterprise solution and in individual transactions. Our technology is designed to capitalize on excess manufacturing capacity and other inefficiencies in the traditional print supply chain to obtain favorable pricing and to deliver high-quality products and services for our clients.

Our proprietary software applications and database, PPM4™, create a fully-integrated solution that stores, analyzes and tracks the production capabilities of our supplier network, as well as quote and price data for each bid we receive and print job we execute. As a result, we believe PPM4™ contains one of the largest independent repositories of equipment profiles and price data for print suppliers in the United States. We leverage our technology to match each print job with the supplier that is optimally suited to meet the client’s needs at a highly competitive price. Our procurement managers use PPM4™ to manage the print procurement process from end-to-end.

Through our network of over 2,700 suppliers, we offer a full range of print, fulfillment and logistics services that allows us to procure printed products on virtually any substrate. The breadth of our product offerings and services and the depth of our supplier network enable us to fulfill up to 100% of the print procurement needs of our clients. By leveraging our technology platform, our clients are able to reduce overhead costs, redeploy internal resources and obtain favorable pricing and service terms. In addition, our ability to track individual transactions and provide customized reports detailing print procurement activity on an enterprise-wide basis provides our clients with greater visibility and control of their print expenditures.

We believe the opportunity exists to expand our business into new geographic markets. Our headquarters are located in Chicago, and approximately 66% of our clients as of December 31, 2005 were located in Illinois. Our objective is to increase our sales in other major print markets in the United States, such as Boston, Los Angeles, Minneapolis, New York and San Francisco. We intend to hire or acquire more account executives within close proximity to these large markets, which accounted for, in aggregate, $18.4 billion of print expenditures in 2005, according to PIA/GATF. In addition, given that the print industry is a global business, over time we intend to evaluate opportunities to access attractive markets outside the United States. For example, in March 2006 we entered into a strategic agreement to grant SNP Corporation Ltd. a non-exclusive, non-transferable license to use certain non-core applications of our software in China, Singapore and Hong Kong.

Recent Developments

Series E Investment.    In January 2006, we issued 10,167,730 Series E preferred shares, or approximately 25% of our equity interests on a fully-diluted basis, to New Enterprise Associates 11, Limited Partnership, NEA Ventures 2005, Limited Partnership and Printworks Series E, LLC in exchange for $50 million in cash, or $4.92 per share. We retained $10 million of these proceeds for working capital and general corporate purposes. We used $40 million of these proceeds to redeem Class A common shares held by our existing stockholders on a pro rata basis at a purchase price of $4.92 per share. See “Certain Relationships and Related Party Transactions—Series E Investment.”

25

SNP Transaction.    In March 2006, we entered into a strategic agreement to grant to SNP Corporation Ltd. a non-exclusive, non-transferable license to use certain non-core applications of our software in China, Singapore and Hong Kong. Pursuant to the terms of the agreement, SNP is paying us $1.0 million in five monthly installments of $200,000, which began in April 2006. The initial term of the agreement is one year and is automatically renewed in April for successive one-year terms in the absence of a termination by either party. In the event the agreement is renewed, SNP will pay us 1% of the gross revenue for all transactions processed through the licensed software during the term of the agreement. In connection with the agreement, we sold 254,065 shares of our Class A common stock to SNP at a price of $4.92 per share for a total purchase price of $1.25 million.

Revenue

We generate revenue through the sale of printed products to our clients. Our revenue grew 226.5%, 139.6% and 97.7% in 2003, 2004 and 2005, respectively, as compared to the corresponding prior years. Our revenue is generated from two different types of clients: enterprise and transactional. Our enterprise jobs usually involve higher dollar amounts and volume than our transactional jobs. We categorize a client as an enterprise client if we have a contract with the client for the provision of printing services on a recurring basis; if the client has signed an open-ended purchase order, or a series of related purchase orders; or if the client has enrolled in our e-stores program, which enables the client to make online purchases of printing services on a recurring basis. We categorize all other clients as transactional. We enter into contracts with our enterprise clients to provide some or a substantial portion of their printed products on a recurring basis. Our contracts with enterprise clients generally have an open-ended term subject to termination by either party upon prior notice of 90 to 180 days. Several of our larger enterprise clients have outsourced substantially all of their recurring print needs to us. We provide printed products to our transactional clients on an order-by-order basis. As of December 31, 2005, we had 69 enterprise clients and, from our inception through December 31, 2005, we served over 1,100 transactional clients. During 2005, enterprise clients accounted for 69% of our revenues, while transactional clients accounted for 31% of our revenues.

Our revenue consists of the prices paid by our clients for printed products. These prices, in turn, reflect the amounts charged to us by our suppliers plus our gross profit. Our gross profit margin, in the case of some of our enterprise clients, is fixed by contract or, in the case of transactional clients, is negotiated on a job-by-job basis. Once either type of client accepts our pricing terms, the selling price is established and we procure the product for our own account in order to re-sell it to the client. We take full title and risk of loss for the product upon shipment. The finished product is typically shipped directly from the supplier to a destination specified by the client. Upon shipment, the supplier invoices us for its production costs and we invoice the client.

Our revenue from enterprise clients tends to generate lower gross profit margins than our revenue from transactional clients because the gross profit margins established in our contracts with larger enterprise clients are generally lower than the gross profit margins we typically earn in our transactional business. Although our enterprise revenue generates lower gross profit margins, our enterprise business tends to be more profitable than our transactional business on an operating profit basis because the commission expense associated with enterprise jobs is generally lower.

The print industry has historically been subject to seasonal sales fluctuations because a substantial number of print orders are placed for the year-end holiday season. We have historically experienced seasonal client buying patterns with a higher percentage of our revenue being earned in our third and fourth quarters. The revenue from our wholly-owned subsidiary, Insight World Group, LLC, is particularly subject to these seasonal fluctuations because its primary products include toys, games and other items that clients generally order in increased quantities in anticipation of the year-end holiday season. We expect these seasonal revenue patterns to continue in the future.

26

Cost of Goods Sold and Gross Profit

Our cost of goods sold consists primarily of the price at which we purchase products from our suppliers. Our selling price, including our gross profit, in the case of some of our enterprise jobs, is based on a fixed gross margin established by contract or, in the case of transactional jobs, is determined at the discretion of the account executive or procurement manager within predetermined parameters. Our gross margins on our enterprise jobs are typically lower than our gross margins on our transactional jobs. As a result, our cost of goods sold as a percentage of revenue for our enterprise jobs is typically higher than those for our transactional jobs. Our gross profit for 2003, 2004 and 2005 was $3.7 million, $8.4 million and $15.6 million, respectively.

Operating Expenses and Income from Operations

Commissions paid to our account executives are a significant component of our operating expenses. The commissions we pay to our account executives are based on the gross profit we collect from our client and are paid after we receive payment from the client. As a percentage of our gross profit, commissions were 15.4%, 21.3% and 22.4% in 2003, 2004 and 2005, respectively.

We accrue for commissions when we recognize the related revenue. Some of our account executives receive a monthly draw to provide them with a more consistent income stream. The cash paid to our account executives in advance of commissions earned is reflected as a prepaid expense on our balance sheet. As our account executives earn commissions, a portion of their commission payment is withheld and offset against their prepaid commission balance, if any. Our prepaid commission balance was $565,000 as of December 31, 2003, $470,000 as of December 31, 2004 and $1.6 million as of December 31, 2005.

Our general and administrative expenses consist mainly of compensation costs for our management team and procurement managers. Our general and administrative expenses also include compensation costs for our finance and support employees, corporate systems, and accounting, legal, facilities and travel and entertainment expenses. We have been able to manage our business with relatively low general and administrative expenses. General and administrative expenses as a percentage of revenue were 14.7%, 11.1% and 9.3% in 2003, 2004 and 2005, respectively.

We agree to provide our clients with printed products that conform with the industry standard of a “commercially reasonable quality,” and our suppliers in turn agree to provide us with products of the same quality. In addition, the quotes we execute with our clients include customary industry terms and conditions that limit the amount of our liability for product defects. Product defects have not had a material adverse effect on our results of operations.

We are required to make payment to our suppliers for completed print jobs regardless of whether our clients make payment to us. To date, the failure of our clients to make required payments has not had a material adverse effect on our results of operations. Our bad debt expense was approximately $125,000, $149,000, and $176,000 in 2003, 2004 and 2005, respectively.

Our income from operations for 2003, 2004 and 2005 was $765,000, $2.1 million and $4.6 million, respectively.

Recapitalization

Prior to the completion of this offering, we intend to recapitalize all outstanding shares of our capital stock into shares of our common stock and consummate a             :             stock split of our common stock immediately following the recapitalization. For a discussion of the recapitalization and stock split, see “Certain Relationships and Related Party Transactions—Recapitalization.”

27

Income Taxes

On January 3, 2006, our company completed a conversion pursuant to which InnerWorkings, LLC, a limited liability company, converted to InnerWorkings, Inc., a corporation. As a limited liability company, we were treated as a partnership for federal, state and local income tax purposes. As a result, all items of income, expense, gain and loss of InnerWorkings were generally reportable on the tax returns of members of InnerWorkings, LLC. Accordingly, we made no provisions for income taxes at the company level through December 31, 2005. Our earnings are now subject to federal, state and local taxes at a combined rate of approximately 39.0%.

Critical Accounting Policies

Revenue Recognition

Revenue is recognized when the product is shipped from a third party to the customer, which is when title transfers. In accordance with EITF Issue 99-19, Reporting Revenue Gross as a Principal versus Net as an Agent, we recognize revenue on a gross basis, as opposed to a net basis similar to a commission arrangement, because we bear the risks and benefits associated with revenue-generated activities by: (1) acting as a principal in the transaction; (2) establishing prices; (3) being responsible for fulfillment of the order; (4) taking the risk of loss for collection, delivery and returns; and (5) marketing our products, among other things.

Goodwill and Other Intangibles

Goodwill represents the excess of purchase price and related costs over the value assigned to the net tangible and identified assets of businesses acquired. Under SFAS No. 142, Goodwill and other Intangible Assets, goodwill and other intangible assets with indefinite lives are not amortized, but instead are tested for impairment annually, or if certain circumstances indicate a possible impairment may exist, in accordance with the provisions of SFAS No. 142. We evaluate recoverability of goodwill using a two-step impairment test approach at the reporting unit level. In the first step, the fair value for the reporting unit is compared to its book value, including goodwill. If the fair value of the reporting unit is less than the book value, a second step is performed, which compares the implied fair value of the reporting unit’s goodwill to the book value of the goodwill. The fair value for the goodwill is determined based on the difference between the fair values of the reporting units and the net fair values of the identifiable assets and liabilities of such reporting units. If the fair value of the goodwill is less than the book value, the difference is recognized as an impairment. As of December 31, 2005, our net goodwill balance was $353,000.

SFAS No. 142 also requires that intangible assets with estimable useful lives be amortized over their respective estimated useful lives to the estimated residual values, and reviewed for the impairment in accordance with SFAS No. 144, Accounting for Impairment or Disposal of Long-Lived Assets. Our intangible assets consist of customer lists and non-compete agreements with account executives and are amortized on the straight-line basis. We believe the customer lists have ten-year useful lives, and we are amortizing the non-compete agreements over the terms of the agreements. As of December 31, 2005, the net balance of our intangible assets was $931,000.

Stock-Based Compensation

Prior to January 1, 2006, we accounted for stock-based employee compensation arrangements in accordance with provisions of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and complied with the disclosure requirements of Financial Accounting Standards Board (FASB) No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure—An Amendment of FASB Statement No. 123. Effective January 1, 2006, we adopted the fair value recognition provisions of FAS 123 (R), Share-Based Payments, using the prospective transition method and Black-Scholes as the option valuation model. Under the transition method, we will continue to account for nonvested equity awards outstanding at the date of adopting Statement 123 (R) in the same manner as they had been accounted for prior to adoption. As a

28

result, under APB No. 25, compensation expense is based on the difference, if any, on the grant date between the estimated fair value of our stock and the exercise price of options to purchase that stock. The compensation expense is then amortized over the vesting period of the stock options.

In May 2006, we granted John R. Walter, the Chairman of our Board, options to purchase 400,000 shares of our common stock, and we granted Steven E. Zuccarini, our Chief Executive Officer, options to purchase 750,000 shares of our common stock, in each case at an exercise price of $4.92 per share, which was the price per share paid by SNP in April 2006. These options will vest ratably over six years. See “Management—Director Compensation” and “Management—Employment Agreements—Employment Agreement with Steven E. Zuccarini.” We also granted one of our employees options to purchase 30,000 shares of our common stock at an exercise price of $4.92 per share. Pursuant to SFAS No. 123 (R), we are required to measure compensation expense for all stock-based payments (including employee stock options). We calculate the expense under the equity method based on the Black-Scholes value of the option at the time of grant. We record the expense in equal amounts as the options vest. This method requires that we make several estimates, including the volatility of our stock price and the expected life of an option. In making these estimates, we relied on historical data as well as management’s judgment. We expect that our expense for these option grants will be approximately $375,000 in 2006 and $550,000 in 2007.

Comparison of three months ended March 31, 2006 and 2005

Revenue

Our revenue increased by $10.0 million, or 80.6%, from $12.4 million during the three months ended March 31, 2005 to $22.4 million during the three months ended March 31, 2006. The revenue growth reflects an increase in enterprise business during the three months ended March 31, 2006, as offset by a decrease in transactional business. We increased our business from enterprise clients to 74% during the three months ended

29

March 31, 2006, up from 53% during the three months ended March 31, 2005. Our revenue from enterprise clients increased by $9.6 million, or by 153.9%, from $6.5 million during the three months ended March 31, 2005 to $16.5 million during the three months ended March 31, 2006. As of March 31, 2006, we had 76 enterprise clients, which was an increase of 24, compared to 52 enterprise clients as of March 31, 2005. Additionally, we performed 3,600 print jobs during the three months ended March 31, 2006, compared to 2,600 print jobs during the three months ended March 31, 2005.

Cost of goods sold

Our cost of goods sold increased by $8.0 million, or 81.0%, from $9.9 million during the three months ended March 31, 2005 to $17.9 million during the three months ended March 31, 2006. The increase reflects the revenue growth during the three months ended March 31, 2006. Our cost of goods sold as a percentage of revenue increased from 79.7% during the three months ended March 31, 2005 to 79.9% during the three months ended March 31, 2006. The slight increase is primarily due to a higher concentration of business with larger enterprise clients.

Gross Profit

Our gross profit as a percentage of revenue decreased from 20.3% during the three months ended March 31, 2005 to 20.1% during the three months ended March 31, 2006. The slight decrease resulted from an increase in our enterprise business, which has historically had lower gross profit margins than our transactional business.

Selling, general and administrative expenses

Commission expense increased by $383,000, or 73.4%, from $522,000 during the three months ended March 31, 2005 to $905,000 during the three months ended March 31, 2006. As a percentage of revenue, commission expense decreased from 4.2% during the three months ended March 31, 2005 to 4.0% during the three months ended March 31, 2006. The decrease is a result of a higher concentration of business with enterprise clients. Historically, lower commission rates have been paid on our enterprise business.

General and administrative expense increased by $700,000, or 52.4%, from $1.4 million during the three months ended March 31, 2005 to $2.1 million during the three months ended March 31, 2006. General and administrative expense decreased as a percentage of revenue from 11.1% during the three months ended March 31, 2005 to 9.3% during the three months ended March 31, 2006. The decrease is primarily due to a decrease in salaries and benefits as a percentage of revenue. Salaries and benefits decreased as a percentage of revenue from 7.4% during the three months ended March 31, 2005 to 5.7% during the three months ended March 31, 2006. The decrease reflects our ability to add clients and account executives to increase our revenue without incurring a corresponding increase in our general and administrative expense.

Depreciation and amortization

Depreciation and amortization expense increased by $81,000, or 122.7%, from $66,000 during the three months ended March 31, 2005 to $147,000 during the three months ended March 31, 2006. The increase in depreciation expense is primarily attributable to purchases of computer hardware and software, equipment and furniture and fixtures as well as capitalization of costs of computer software for internal use in accordance with Statement of Position 98-1 during 2005. The increase in amortization expense is a result of the amortization of the intangible assets acquired in connection with our purchase of the remaining 49% ownership interest in Insight World Group, LLC, which was completed in March 2005.

Income from operations

Income from operations increased by $843,000, or 145.1%, from $557,000 during the three months ended March 31, 2005 to $1.4 million during the three months ended March 31, 2006. As a percentage of revenue,

30

income from operations increased from 4.4% during the three months ended March 31, 2005 to 6.1% during the three months ended March 31, 2006. The increase in income from operations as a percentage of revenue is a result of a decrease in our selling, general and administrative expenses as a percentage of revenue.

Minority interest income

Minority interest income decreased $58,000 from $58,000 during the three months ended March 31, 2005 to zero during the three months ended March 31, 2006. Our minority interest income during the three months ended March 31, 2005 was attributable to the ownership interest we did not own in Insight World Group, LLC. In March 2005, we purchased the remaining 49% ownership interest in Insight. The minority interest income was reduced to zero as a result of this purchase and the resulting ownership of 100% of the business.

Other income and expense

Other income and expense increased $85,000 from expense of $40,000 during the three months ended March 31, 2005 to income of $45,000 during the three months ended March 31, 2006. The increase is due to an increase in interest income from $11,000 during the three months ended March 31, 2005 to $99,000 during the three months ended March 31, 2006. The increase in interest income is a result of our issuance of $50 million of Series E preferred stock on January 3, 2006. We retained $10 million of these proceeds, which were invested in money market funds from January 3, 2006 to March 31, 2006.

Provision for income taxes

Provision for income taxes increased by $584,000 from zero during the three months ended March 31, 2005 to $584,000 during the three months ended March 31, 2006. The provision for income taxes was zero during the three months ended March 31, 2005 because we were a limited liability company (LLC) and, as a result, did not pay income taxes. The income of the company flowed through to the members of the LLC. We converted from an LLC to a corporation on January 3, 2006. As a result, we have a provision for federal and state income taxes for the three months ended March 31, 2006.

We used $40 million of the $50 million we received in exchange for the issuance of our Series E preferred stock to redeem Class A common shares held by our existing stockholders in connection with our conversion from a limited liability company to a corporation. The cash distribution was taxable to our stockholders and resulted in a $40 million step-up in the basis of our assets for tax purposes. As a result of the $40 million step-up, we recognized a deferred tax asset of $15.6 million, for which we recorded a valuation allowance of $7.8 million and a corresponding net increase to additional paid in capital of $7.8 million. For the three months ended March 31, 2006, the provision for federal and state income taxes was $584,000, resulting in an effective tax rate of 39%.

Net income

Net income increased by $251,000, or 43.7%, from $575,000 during the three months ended March 31, 2005 to $826,000 during the three months ended March 31, 2006. Net income as a percentage of revenue decreased from 4.6% during the three months ended March 31, 2005 to 3.7% during the three months ended March 31, 2006. Without the provision for income taxes for the three months ended March 31, 2006, net income as a percentage of revenue increased to 6.3%. The increase in net income as a percentage of revenue is largely a result of improved operating profit. Selling, general and administrative expenses as a percentage of revenue decreased from 15.3% during the three months ended March 31, 2005 to 13.3% during the three months ended March 31, 2006.

Comparison of years ended December 31, 2005 and 2004

Revenue

Our revenue increased by $38.0 million, or 97.7%, from $38.9 million in 2004 to $76.9 million in 2005. The revenue growth reflects an increase in transactional and enterprise business during 2005. We increased our

31

business from enterprise customers to 69% during 2005 up from 50% during 2004. Our revenue from enterprise clients increased by $33.3 million, or by 172.5%, to $52.8 million during 2005 compared to $19.5 million during 2004. As of December 31, 2005, we had 69 enterprise clients under contract, which was an increase of 23 compared to 46 enterprise clients under contract as of December 31, 2004. Additionally, we performed 10,700 print jobs during 2005, compared to 6,900 print jobs during 2004.

Cost of goods sold

Our cost of goods sold increased by $30.8 million, or 101.0%, from $30.5 million in 2004 to $61.3 million in 2005. The increase reflects the growth in revenue in 2005. Our cost of goods sold as a percentage of revenue increased from 78.4% in 2004 to 79.7% in 2005. The increase is primarily due to a higher concentration of business with enterprise clients which typically have lower commission rates.

Gross profit

Our gross profit as a percentage of revenue, which we refer to as gross margin, decreased from 21.6% in 2004 to 20.3% in 2005. The decrease primarily resulted from an increase in our enterprise business, which has historically had lower gross profit margins than our transactional business.

Selling, general and administrative expenses

Commission expense increased by $1.7 million, or 95.3%, from $1.8 million in 2004 to $3.5 million in 2005. As a percentage of revenue, commission expense decreased from 4.6% in 2004 to 4.5% in 2005. The decrease resulted from increased enterprise business, which typically have lower commission rates.

General and administrative expenses increased by $2.8 million, or 64.8%, from $4.3 million in 2004 to $7.1 million in 2005. As a percentage of revenue, general and administrative expenses decreased from 11.1% in 2004 to 9.3% in 2005. The decrease is due in part to a decrease in salaries and benefits as a percentage of revenue. Salaries and benefits decreased as a percentage of revenue from 6.0% in 2004 to 5.5% in 2005. The decrease reflects our ability to add clients and account executives to increase our revenue without incurring a corresponding increase in our general and administrative expenses.

Depreciation and amortization

Depreciation and amortization expense increased by $165,000, or 74.0%, from $223,000 in 2004 to $388,000 in 2005. The increase in depreciation expense is primarily attributable to purchases of computer hardware and software, equipment and furniture and fixtures during 2005. The increase in amortization expense is due to the acquisition of intangible assets of Ocular Group, LLC (Ocular), a print broker, in April 2004. The Ocular acquisition included the purchase of intangible assets, including customer lists and sales executives non-compete agreements with values of $889,000 that are being amortized on a straight-line basis over a useful life of five and ten years.

Income from operations

Income from operations increased by $2.5 million, or 122.1%, from $2.1 million in 2004 to $4.6 million in 2005. As a percentage of revenue, income from operations increased from 5.3% in 2004 to 6.0% in 2005. The increase in income from operations as a percentage of revenue reflects a reduction in selling, general and administrative expenses as a percentage of revenue.

Minority interest expense

Minority interest expense decreased by $250,000 from expense of $192,000 in 2004 to income of $58,000 in 2005. For the first two months of 2005, Insight had an operating loss. As a result, we recorded minority interest

32

income for that period. Upon our acquisition of the 49% ownership interest in Insight that we did not already own in March 2005, we ceased recording minority interest expense.

Other income and expense

Interest expense decreased by $34,000, or 25.4%, from $132,000 in 2004 to $98,000 in 2005. The decrease is the result of maintaining a lower average daily balance under our bank line of credit.

Net Income

Net income increased by $2.8 million, or 163.7%, from $1.8 in 2004 to $4.6 million in 2005. As a percentage of revenue, net income increased from 4.5% in 2004 to 6.0% in 2005. The increase in net income as a percentage of revenue is largely a result of improved operating profit. Selling, general and administrative expenses as a percentage of revenue decreased from 15.7% in 2004 to 13.8% in 2005.

Comparison of years ended December 31, 2004 and 2003

Revenue

Our revenue increased by $22.7 million, or 139.6%, from $16.2 million in 2003 to $38.9 million in 2004. The revenue growth reflects an increase in transactional and enterprise business during 2004. We increased our business from enterprise customers to 50% during 2004 up from 37% during 2003. Our revenue from enterprise clients increased by $13.5 million, or 225.0%, to $19.5 million during 2004 compared to $6.0 million during 2003. As of December 31, 2004, we had 46 enterprise clients, which was an increase of 32 compared to 14 enterprise clients as of December 31, 2003. Additionally, we performed 6,900 print jobs during 2004, compared to 2,000 print jobs during 2003.

Cost of goods sold

Our cost of goods sold increased by $18.0 million, or 144.1%, from $12.5 million in 2003 to $30.5 million in 2004. The increase reflects the growth in revenue in 2004. Revenue from enterprise clients and Insight accounted for a higher percentage of our revenue. Our gross margins on our enterprise jobs and Insight’s gross margins are typically lower than those on our transactional jobs. As a result, cost of goods sold as a percentage of revenue increased from 76.9% in 2003 to 78.4% in 2004.

Gross profit

Our gross margin decreased from 23.1% in 2003 to 21.6% in 2004. The decrease primarily resulted from an increase in business with enterprise clients and Insight’s lower gross margin. Insight’s gross margin decreased from 17.8% in 2003 to 16.3% in 2004.

Selling, general and administrative expenses

Commission expenses increased by $1.2 million, or 209.9%, from $577,000 in 2003 to $1.8 million in 2004. As a percentage of revenue, commission expense increased from 3.6% in 2003 to 4.6 % in 2004. The increase is due to a higher percentage of revenue being generated from commissioned accounts.

General and administrative expenses increased by $1.9 million, or 81.2%, from $2.4 million in 2003 to $4.3 million in 2004. As a percentage of revenue, general and administrative expenses decreased from 14.6% in 2003 to 11.1% in 2004. The decrease is due in part to a decrease in salaries and benefits as a percentage of revenue. Salaries and benefits decreased as a percentage of revenue from 8.9% in 2003 to 6.0% in 2004. The decrease reflects our ability to add clients and account executives to increase our revenue without incurring a corresponding increase in our general and administrative expenses.

33

Depreciation and amortization

Depreciation and amortization expense increased by $205,000 from $18,000 in 2003 to $223,000 in 2004. The increase in depreciation expense is primarily attributable to purchases of computer hardware and software, equipment and furniture and fixtures in 2004. The increase in amortization expense is due to the acquisition of Ocular in April 2004. The acquisition of Ocular included the purchase of intangible assets with values of $889,000 that are being amortized on a straight-line basis over a useful life of five and ten years.

Income from operations

Income from operations increased by $1.3 million, or 171.0%, from $765,000 in 2003 to $2.1 million in 2004. As a percentage of revenue, income from operations increased from 4.7% in 2003 to 5.3% in 2004. The increase in income from operations as a percentage of revenue reflects a reduction in general and administrative expenses as a percentage of revenue as a result of our improved operating leverage.

Minority interest expense

Minority interest expense increased by $184,000 from $8,000 in 2003 to $192,000 in 2004. The increase is due to our sale of a 49% ownership interest in Insight in October 2003.

Other income and expense

Interest expense increased by $43,000, or 48.6%, from $89,000 in 2003 to $132,000 in 2004. The increase is due to the interest payments to the holders of our Series D preferred stock made in 2004.

Net Income

Net income increased by $1.1 million, or 161.9%, from $671,000 in 2003 to $1.8 million in 2004. As a percentage of revenue, net income increased from 4.1% in 2003 to 4.5% in 2004.

Impact of Inflation

We believe that our results of operations are not materially impacted by moderate changes in the inflation rate. Inflation and changing prices did not have a material impact on our operations in 2003, 2004, 2005 or the three months ended March 31, 2006.

34

Liquidity and Capital Resources

Since inception, we have financed our operations through private sales of common and preferred equity, with net proceeds of $18.5 million, bank loans and internally generated positive cash flow. As of March 31, 2006, we had $9.5 million in cash and cash equivalents and $14.3 million in working capital.

Cash provided by operating activities decreased from $1.0 million in the three months ended March 31, 2005 to a use of $1.6 million in the three months ended March 31, 2006. The decrease resulted from a significant increase in the accounts receivable balance of $2.0 million during the three months ended March 31, 2006 compared to the accounts receivable balance decrease of $2.6 million in the prior period. Additionally, the accounts payable balance increased by only $147,000 during the three months ended March 31, 2006, largely as a result of the company taking advantage of early pay discount terms with vendors at the end of March.

In 2005, cash provided by operating activities increased by $112,000 to $967,000 from $855,000 in 2004. The increase in cash provided by operating activities increased by only $112,000 compared to an increase of net income of $2.9 million due to the significant increase in prepaid expenses and other. Prepaid expenses increased by over $1.0 million due to professional fees incurred in 2005 in connection with this offering. Additionally, other prepaid expenses increased by over $1.0 million related to prepaid paper and other vendor costs for jobs that were not ready to ship to the customer. The increase in this current asset reduced the overall net cash provided by operations.

In 2004, cash provided by operating activities increased $1.6 million to $855,000 compared with cash used in operating activities of $697,000 in 2003. The increase in cash provided by operating activities reflects an improvement in our net income and that growth in our accounts receivable outpaced our accounts payable and other short-term liabilities.

For the three months ended March 31, 2006, cash used in investing activities decreased $32,000 to $279,000 from $311,000 in the three months ended March 31, 2005. The decrease is a result of a $125,000 investment in Echo Global Logistics, LLC during the three months ended March 31, 2005.

In 2005, cash used in investing activities increased $209,000 to $1.2 million from $991,000 in 2004. In 2004, $681,000 was used to purchase the Ocular Group, LLC while $309,000 was used for the purchase of property and equipment. In 2005, the purchase of property and equipment increased to $1.0 million related to the purchase of new hardware, software and the capitalization of internal software costs.

Cash used in investing activities increased $921,000 to $991,000 in 2004 from $70,000 in 2003. The improvement reflects purchases of property and equipment and the purchase of Ocular.

For the three months ended March 31, 2006, cash provided by financing activities increased $7.5 million to $8.4 million from $873,000 in the three months ended March 31, 2005. The increase is due to the net raise of $10.0 million of capital from the Series E round of financing that was funded on January 3, 2006. The increase was $7.5 million because we raised $2.0 million of capital from the second portion of the Series D round of financing that was funded in February 2005.

In 2005, cash provided by financing activities increased by $1.1 million to $1.7 million from $646,000 2004. The increase in cash provided by financing activities is a result of usage of the bank facility during 2005. Additionally, the company raised capital through the sale of $2.0 million of Series D preferred stock in February 2005.

In 2004, cash provided by financing activities decreased by $854,000 to $646,000 compared with $1.5 million in 2003. The decrease in cash provided by financing activities primarily reflects proceeds from private sales of common and preferred equity.

Capital expenditures were $70,000 in 2003, $310,000 in 2004, $1.0 million in 2005 and $279,000 in the three months ended March 31, 2006. Our capital expenditures historically consisted of purchases of resources to

35

manage our operations, including computer hardware and software, office furniture and equipment and leasehold improvements. We expect that our capital expenditures will continue to increase in the future. Since our inception, we have generally funded capital expenditures either through the use of working capital or with capital leases.

We have a $10.0 million credit facility with Bank One, NA, $2.2 million was outstanding on the line as of March 31, 2006. The maximum amount outstanding under our credit facility cannot exceed 80% of the book value of our eligible accounts receivable. Our credit facility contains limitations on our ability to incur indebtedness, create liens and make certain investments. Advances made under our credit facility accrue interest at a per annum rate equal to the prime rate.

We anticipate that our operating expenses and planned capital expenditures will constitute a material use of cash. In addition, we may utilize cash to fund acquisitions of or strategic investments in complementary businesses and to expand our sales force. Although we can provide no assurances, we believe that the net proceeds from this offering, together with our available cash and cash equivalents and amounts available under our line of credit, should be sufficient to meet our working capital and operating expenditure requirements for the foreseeable future. Thereafter, we may find it necessary to obtain additional equity or debt financing. In the event additional financing is required, we may not be able to raise it on acceptable terms or at all.

Contractual Obligations

As of December 31, 2005, we had the following contractual obligations:

	Payments due by period
	Total		Less than 1 year		1-3 years		3-5 years		More than 5 years
	(in thousands)

Total	$	11,609	$	3,600	$	1,563	$	1,890	$	4,556

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements.

Quantitative and Qualitative Disclosures about Market Risk

Commodity Risk

We are dependent upon the availability of paper and paper prices represent a substantial portion of the cost of our products. The supply and price of paper depends on a variety of factors over which we have no control, including environmental and conservation regulations, natural disasters and weather.

Interest Rate Risk

We have exposure to changes in interest rates on our line of credit. The interest rate on our line of credit fluctuates based on the prime rate. Assuming the $10.0 million line of credit was fully drawn, a 1.0% increase in the prime rate would increase our annual interest expense by $100,000, without taking into account our expected application of a portion of our net proceeds from this offering to pay down the line of credit.

Our interest income is sensitive to changes in the general level of U.S. interest rates, in particular because all of our investments are in cash equivalents. The average duration of all of our investments as of March 31, 2006 was less than three months. Due to the short-term nature of our investments, we believe that there is no material risk exposure.

We procure printed products for clients across a wide range of industries, such as advertising, consumer products, publishing and retail. Our clients fall into two categories, enterprise and transactional. We enter into arrangements with our enterprise clients to provide some, or substantially all, of their printed products, typically on a recurring basis. We provide printed products to our transactional clients on an order-by-order basis. For the year ended December 31, 2005, enterprise and transactional clients accounted for 69% and 31% of our revenue, respectively.

We were formed in 2001 and commenced operations in 2002. From our inception through December 31, 2005, we served over 1,100 clients, received approximately 96,000 bids and executed approximately 26,000 print jobs through over 1,100 suppliers. We have increased our revenue from $5.0 million in 2002 to $76.9 million in 2005, representing a compound annual growth rate of 148%. In 2005, our revenue was $76.9 million, compared to $38.9 million in 2004. For the three months ended March 31, 2006, our revenue was $22.4 million, compared to $12.4 million for the three months ended March 31, 2005.

Industry Overview

Our business of providing print procurement solutions intersects two large and growing industries, commercial printing and business process outsourcing, or BPO. Total shipments in the worldwide commercial print industry were projected to be approximately $367 billion in 2005 and are expected to increase by an average of $8 billion per year through 2009, according to a 2005 Datamonitor global commercial printing industry profile. The print industry includes the following product categories:

• direct mail and other direct marketing materials;

• basic business printing, including business forms, stationery and business cards;

• promotional printing, which includes brochures, direct mail and catalogs;

37

• publications, including magazines, books and directories;

• bill of material printing, which consists of customized packaging, labels and other shipping materials;

• promotional products, such as t-shirts, calendars and advertisements; and

• multimedia, including CDs and DVDs.

In addition, the U.S. print industry is highly fragmented, with an estimated 39,300 printing plants. In 2005, the ten largest commercial print companies accounted for only approximately 16% of the total domestic print market. The traditional process of designing, procuring and producing a print order requires extensive collaboration by printers, designers, brokers and other middlemen and is often highly inefficient for the customer, who typically pays a mark-up at each intermediate stage of the supply chain. Print procurement is often dispersed across several areas of a business enterprise, including sales, marketing, communications and finance.

To become more competitive, many businesses seek to focus on core competencies and outsource non-core business functions, such as print procurement. The National Association of Procurement Managers ranked print procurement as the second most significant resource procurement outsourcing opportunity for U.S. businesses, underscoring this trend. According to a 2005 IDC global BPO forecast, the worldwide market for BPO is estimated to grow from $422 billion in 2005 to $641 billion in 2009, representing a compound annual growth rate of 11%. Consolidating all print activities across the organization represents an opportunity to reduce total print expenditure and decrease the number of vendors in the print supply chain. Applying software and database technology to manage the print procurement process also provides for enhanced tracking and auditing capabilities.

In recent years, the print industry has been impacted by developments in technology, including enhanced output capacity of printing presses and increased utilization of Internet-based communications and digital printing. These developments have lowered barriers to entry and reduced the utilization of printing presses. As a result, the print industry has historically experienced significant excess manufacturing capacity and the market for printed products has become increasingly commoditized. As developments in technology enable more print companies to provide a broad range of products and services, there are fewer opportunities for print vendors to charge premium prices based on product and service differentiation.

We seek to capitalize on the trends impacting the commercial print industry and the movement towards increased outsourcing of non-core business functions by leveraging our propriety technology, expansive database, extensive supplier network and purchasing power.

Our Solution

Utilizing our proprietary technology and database, we are able to create a competitive bid process to procure, purchase and deliver printed products to our clients. Our network of over 2,700 suppliers offers a wide variety of printed products and a full range of print, fulfillment and logistics services.

Our print procurement software seeks to capitalize on excess manufacturing capacity and other inefficiencies in the traditional print supply chain. We believe that the most competitive price bids we obtain from our suppliers are submitted by the suppliers with the most unused capacity. We utilize our technology and a competitive bid process to:

• greatly increase the number of suppliers that our clients can efficiently access;

• obtain favorable pricing and deliver high quality products and services for our clients; and

• aggregate our purchasing power.

38

Our proprietary software applications and database, PPM4^™, streamline the print procurement process for our clients by eliminating inefficiencies within the traditional print supply chain and expediting production. However, our technology cannot manage all of the variables associated with procuring a print job, which often involves extensive collaboration among numerous parties. Effective management of the procurement process requires that dedicated and experienced personnel work closely with both clients and print suppliers. Our account executives and procurement managers perform that critical function.

Account executives act as the primary sales staff to our clients. Procurement managers manage the entire print procurement process for our clients to ensure timely and accurate delivery of the finished product. For each print job we receive, a procurement manager uses our technology to gather print specifications, solicit bids from the optimal suppliers, establish pricing with the client, manage print production and purchase and coordinate the delivery of the finished product.

Each client is assigned an account executive and procurement manager, who develop contacts with client personnel responsible for authorizing and making print purchases. Our largest clients often are assigned multiple procurement managers. In certain cases, our procurement managers function on-site at the client. In other cases, we designate an employee of the client to function as our procurement manager and reimburse the client for the employee’s compensation costs. Whether on-site or off-site, a procurement manager functions as a virtual employee of the client. As of December 31, 2005, we had 52 procurement managers, including eight procurement managers working on-site at our clients.

Although our clients fall into two categories, enterprise and transactional, the procurement process for each client category is substantially similar. A typical print job moves through our solution in ten steps.

Step 1—Gather print specifications.    After the account executive or procurement manager identifies a sale opportunity, a procurement manager discusses the details and timeline for the print job with the client. PPM4^TM automatically generates a customized data entry screen based on the type of printed product and guides the procurement manager to enter the required job specifications.

Step 2—Select appropriate suppliers.    Based on the historical transaction data and supplier capability information contained in our database, PPM4^TM generates a list of potential suppliers within our extensive network with the most efficient equipment profiles to produce the job. The procurement manager may select suppliers from this list or select suppliers suggested by the client. Our technology also enables the procurement manager to disaggregate the job into its component parts and put each part out for competitive bid in order to generate additional savings for the client. After selecting the list of optimal suppliers, the procurement manager electronically transfers the job specifications into an e-mail or e-fax in the form of a request for proposal and sends it to those suppliers.

Step 3—Receive bids from suppliers.    The selected suppliers respond to our request for proposal by submitting bids to us. Upon receipt, the procurement manager enters the bid information into our database and generates a report that details and sorts the bids by cost, quality and logistical considerations.

Step 4—Compare bids to proprietary data.    The procurement manager uses PPM4^TM to compare the bids received from the suppliers to similar transactions in our database. If the current bids deviate from the competitive price range suggested by this data in a manner that is unfavorable to our client, the procurement manager uses our data to negotiate more favorable pricing with the selected suppliers or re-submits the specifications to different suppliers.

Step 5—Submit quote to client.    The procurement manager works with the account executive to prepare a price quote for the print job. The account executive submits the quote to the client, specifying the total cost to the client for the printed product and the timing and delivery terms.

Step 6—Execute quote and print order.    The client accepts the quote by executing it and returning a signed copy to us. The procurement manager uses PPM4 ^TM to automatically convert the quote into a print order. The

39

print order is sent by e-mail or e-fax to the approved supplier or suppliers for execution. We are now contractually obligated to provide the product to our client and the supplier or suppliers are contractually obligated to provide the product to us. The supplier begins the print process.

Step 7—Manage print process.    The completion of the print process is managed by the procurement manager through a checklist of dates, milestones and deliverables that is monitored electronically. PPM4 ^TM generates automatic reminders to ensure the product is properly produced in accordance with the client’s specifications and timeline.

Step 8—Perform final quality control check.    Prior to production of the entire print quantity, the supplier submits a contract proof of the finished product to the client and procurement manager for approval. Upon written approval of the proof by the client, the supplier prints the finished product.

Step 9—Deliver finished product.    When printing is completed, we purchase the finished product from the supplier and coordinate delivery to the destination specified by the client. We take full title and risk of loss for the product from shipment until it is received and paid for by the client.

Step 10—Generate and reconcile invoices.    Upon shipment of the finished product, the supplier issues an invoice to us for the cost of the job and our technology automatically converts the quote executed by our client into an invoice that we issue to the client. PPM4^TM reconciles the supplier’s invoice to the print order to ensure that the supplier adhered to the pricing and other terms set forth in the print order.

The duration of this ten-step process varies based on the type of printed product. For example, this process may take less than 24 hours for limited quantities of a four-page brochure, but last over one month for 1,000,000 copies of a hard cover book.

We regularly request that our clients complete a customer scorecard, which allows them to rate us and our suppliers based on product quality, customer service and overall satisfaction. The data contained in these scorecards is stored in our database and used by our procurement managers during the supplier selection process.

Our Proprietary Technology

PPM4^TM is a fully-integrated, proprietary solution that stores equipment profiles for our supplier network and price data for each job we quote and execute, which allows us to match each print job with the supplier in our network that is optimally suited to produce the job at a highly competitive price. Our technology also allows us to efficiently manage the critical aspects of the print procurement process, including gathering job specifications, identifying suppliers, establishing pricing, managing print production and coordinating purchase and delivery of the finished product.

Our database stores the production capabilities of our supplier network, as well as price and quote data for each bid we receive and transaction we execute. As a result, we believe PPM4^TM contains one of the largest independent repositories of equipment profiles and price data for print suppliers in the United States. Our procurement managers use this data to discover excess print manufacturing capacity, select optimal suppliers, negotiate favorable pricing, and efficiently procure high-quality products and services for our clients.

With each new print job process, we collect and store additional data in our proprietary database. As the number of print jobs we complete increases, our database further enhances our competitive position and our ability to obtain favorable pricing for our clients.

We believe PPM4^TM allows us to procure print more efficiently than traditional manual or semi-automated systems used by many printers and print brokers in the marketplace. PPM4^TM includes the following features:

Ÿ “4caster.”    Our proprietary database provides real-time cost estimates for potential print jobs within our major product categories based upon the historical data we have collected from print jobs with

40

similar specifications. These estimates are used by our account executives during the sales process and procurement managers to compare bids and negotiate favorable pricing. Some of our largest suppliers have provided us with pricing tables covering specific product categories, which have also enhanced our ability to discover competitive pricing.

Ÿ Customized order management.    PPM4^TM automatically generates customized data entry screens based on product type and guides the procurement manager to enter the required job specifications. For example, if a procurement manager selects “envelope” in the product field, the screen will automatically prompt the procurement manager to specify the size, paper type, window size and placement and display style.

Ÿ Cost management.    PPM4^TM reconciles supplier invoices to executed print orders to ensure the supplier adhered to the pricing and other terms contained in the print order. In addition, it includes checks and balances that allow us to monitor important financial indicators relating to a print order, such as projected gross margin and significant job alterations.

Ÿ Standardized reporting.    Our solution generates transaction reports that contain quote, supplier capability, price and customer service information regarding the print jobs the client has completed with us. These reports can be customized, sorted and searched based on a specified time period or the type of printed product, price or supplier. In addition, the reports give our clients insight into their print spend for each individual print job and on an enterprise-wide basis, which allows the client to track the amounts it spends on printed products.

Ÿ Task-tracking.    Our solution creates a work order checklist that sends e-mail reminders to our procurement managers regarding the time elapsed between certain milestones and the completion of specified deliverables. These automated notifications enable our procurement managers to focus on more critical aspects of the print process and eliminate delays.

Ÿ Open architecture.    PPM4^TM allows us to integrate clients and suppliers into our solution. Some of our larger clients have limited, secure access to our database, which they can use to directly access their transaction data.

Ÿ Historical price baseline.    Some of our larger clients have provided us with pricing data for print jobs they completed before they began to use our solution. For these clients, PPM4^TM automatically compares our current price for a print job to the price obtained by the client for a comparable historical job, which allows us to demonstrate on an ongoing basis the cost savings we provide.

We have also created customized Internet-based stores, which we refer to as IW stores, for certain of our clients that allow them to order pre-selected products, such as personalized business stationery, marketing brochures and promotional products, through an automated ordering process.

Our Clients

We procure printed products for corporate clients across a wide range of industries, such as advertising, consumer products, manufacturing, publishing and retail. Our clients also include printers that outsource jobs to us because they do not have the requisite capabilities or capacity to complete an order. From our inception through December 31, 2005, we served over 1,100 clients, received approximately 96,000 bids and executed approximately 26,000 print jobs through 1,100 suppliers. For the year ended December 31, 2005, Alliance Publishing Group accounted for 16% of our revenue. Revenue from our top ten clients accounted for 43% and 46% of our revenue during the years ended December 31, 2004 and 2005, respectively.

We generate revenue by procuring and purchasing printed products from our suppliers and selling those products to our clients. Our clients fall into two categories, enterprise and transactional. We enter into contracts

41

with our enterprise clients to provide some or substantially all of their printed products typically on a recurring basis. Our contracts with our enterprise clients generally have an open-ended term with a termination right upon advance notice ranging from 90 to 180 days. For the years ended December 31, 2004 and 2005, enterprise clients accounted for 50% and 69% of our revenue, respectively. We provide printed products to our transactional clients on an order-by-order basis. For the years ended December 31, 2004 and 2005, transactional clients accounted for 50% and 31% of our revenue, respectively.

As part of our growth strategy, we seek to expand our base of transactional clients by hiring account executives, or acquiring groups of them, with established client relationships. We also aim to sell our enterprise solution to our transactional clients to capture a greater portion of their recurring print expenditures. We estimate that the total annual print expenditures for our 667 transactional clients during the year ended December 31, 2005 were in excess of $750 million.

As of December 31, 2005, approximately 66% of our clients were located in Illinois. In order to expand our client base, we intend to recruit more account executives in other major print markets in the United States, such as Boston, Los Angeles, Minneapolis, New York and San Francisco. We believe that the breadth of our supplier network will allow us to expand into new geographic markets with little upfront cost.

Of our 50 largest clients from 2004, 49 placed orders with us during 2005. We believe that our high level of client retention demonstrates the compelling value proposition that we provide to our clients.

Our Products and Services

We offer a full range of print, fulfillment and logistics services that allows us to procure printed products on virtually any substrate. The printed products we procure for our clients may be printed with any of the eight major types of printing, which include offset sheet-fed, web offset, digital offset, letterpress, screen printing, waterless, flexography and gravure, as well as several forms of specialty printing.

Our major products include:

We offer a comprehensive range of fulfillment and logistics services, such as kitting and assembly, inventory management and pre-sorting postage. These services are often essential to the completion of the finished product. For example, we assemble multi-level direct mailings, insurance benefits packages and coupons and promotional incentives that are included with credit card and bank statements. We also provide creative services, including copywriting, graphics and website design, identity work and marketing collateral development, and pre-media services, such as image and print-ready page processing and proofing capabilities.

We agree to provide our clients with products that conform with the industry standard of a “commercially reasonable quality” and our suppliers in turn agree to provide us with products of the same quality. The quotes we execute with our clients include customary provisions that limit the amount of our liability for product defects. To date, we have not experienced significant claims or liabilities relating to defective products.

42

Our Supplier Network

Our network of 2,700 suppliers include printers, graphic designers, paper mills and merchants, digital imaging companies, specialty binders, finishing and engraving firms and fulfillment and distribution centers. These suppliers have been selected from among thousands of potential suppliers worldwide based on their ability to effectively serve our clients on the basis of price, quality and customer service. Our suppliers include 61 of the 100 largest printers in the United States, including eight of the top ten. The suppliers in our network produced more than $43 billion of printed products in 2005. We direct requests for proposal from our clients to potential suppliers based on historical pricing data, quality control rankings, geographic proximity to a client or other criteria specified by our clients.

In 2005, our top 10 suppliers accounted for approximately 40% of the products we sold, and our top three suppliers accounted for approximately 21% of the products we sold. As of December 31, 2005, a majority of our top 100 suppliers had executed supply and service agreements with us. These agreements have an open-ended term with a termination right on 60 days prior written notice and contain non-solicitation provisions that prohibit the supplier from soliciting any client for which the supplier has executed print order for a specified period, generally 24 months, after the expiration of the agreement. Our contractual relationship with the remaining suppliers in our network is governed solely by the print orders we execute with those suppliers on an order-by-order basis.

We have established a quality control program that is designed to ensure that we deliver high quality printed products and services to our clients through the suppliers in our network. As part of this program, we train our procurement managers to accurately gather job specifications and create a checklist to ensure that each item in the print order has been approved by the client. In addition, we regularly request that our clients complete customer scorecards, which are stored in our database and converted into quality control reports. These quality control reports are accessible to our procurement managers through PPM4^TM and are used during the supplier selection process. Our quality control standards are designed to ensure that our clients receive high quality printed products regardless of the supplier that prints the product.

Sales and Marketing

Our account executives sell our print procurement services to corporate clients in the United States. As of December 31, 2005, we had 86 account executives, 66 of whom were independent contractors and 20 of whom were employees, located in 17 cities across the U.S. We hired nine account executives in 2002, 17 in 2003, 20 in 2004 and 33 in 2005. In addition to our account executives, we have two business development employees responsible for generating sales opportunities with large companies. Our agreements with our account executives require them to market and sell print procurement services for us on an exclusive basis and contain non-compete and non-solicitation provisions that apply during and for a specified period after the term of their service.

Our new client acquisition efforts generally are targeted geographically based on the location of our account executives. Our account tracking solution, IW Pipeline™, which assigns account responsibility for both existing and prospective clients, monitors the sales conversion process and tracks sales activity. An important aspect of our sales process is our periodic analysis of a prospective client’s historic print expenditures, including production and payroll expenses, to demonstrate the potential savings that could be achieved by using our solution.

We expect to continue our growth by recruiting and retaining highly qualified account executives and providing them with the tools to be successful in the marketplace. There are a large number of print sales representatives in North America and we believe that we will be able to identify qualified account executives from this pool of individuals. To coordinate this process, we employ a full-time recruiter whose activities are supplemented by several executive search firms. Candidates are recruited through Internet postings, advertisements in industry publications, industry event attendance, Internet research, referrals and word-of-mouth networking. We also expect to augment our sales force through selective acquisitions of print service businesses, including print brokers, that include experienced sales personnel with established client relationships.

43

We believe that we offer account executives an attractive opportunity in the print industry because they can utilize our vast supplier network, proprietary pricing data and customized order management solution to sell to their clients virtually any printed product at a highly competitive price. In addition, the diverse production and service capabilities of the suppliers in our network provide our account executives the opportunity to deliver a more complete product and service offering to their clients. We believe we can better attract and retain experienced account executives than our competitors because of the breadth of products offered by our supplier network.

To date, we have been successful in attracting and retaining qualified account executives. The account executives we have hired through December 31, 2005 had an average of over 17 years of sales experience in the print industry, which in certain cases included employment as sales representatives for some of the largest printers in the United States. The integration process consists of training with our sales management, as well as access to a variety of sales and educational resources that are available on our Intranet. In addition, we conduct monthly sales meetings that focus on best practices and industry trends. Because the account executives we hire generally have significant sales experience, they can begin marketing our services after limited training on our model and systems.

Competition

We operate in the print industry and several print-related industries, including paper and pulp, graphics art and digital imaging and fulfillment and logistics. As a result, we compete on some level with virtually every company that is involved in printing, from printers to graphic designers, pre-press firms, paper manufacturers and fulfillment companies.

Our primary competitors are printers that employ traditional methods of marketing and selling their printed materials. The printers with which we compete generally own and operate their own printing equipment and typically serve clients only within the specific product categories and print types that their equipment produces. Some of these printers, such as Banta, Quad/Graphics, Quebecor and R.R. Donnelley, have larger client bases and significantly more resources than we do.

We also compete with a number of print distributors and brokers. These competitors generally do not own or operate printing equipment, and typically work with a limited number of suppliers and have minimal financial investment in the quality of the products produced for their clients. Our industry experience indicates that several of these competitors, such as Cirqit, Workflow/Relizon and Newline/Noosh, offer print procurement services or enterprise software applications for the print industry.

The principal elements of competition in print procurement are price, product quality, customer service and reliability. Although we believe our business delivers products and services on competitive terms, our business and the print procurement industry are relatively new and are evolving rapidly. Print buyers may prefer to utilize the traditional services offered by the printers with whom we compete. Alternatively, some of these printers may elect to compete with us directly by offering print procurement services or enterprise software applications, and their well-established client relationships industry knowledge, brand recognition, financial and marketing capabilities, technical resources and pricing flexibility may provide them with a competitive advantage over us.

Intellectual Property

We rely primarily on a combination of copyright, trademark and trade secret laws and restrictions to protect our intellectual property rights. We also protect our proprietary technology through confidentiality and non-disclosure agreements with our employees and independent contractors.

Our IT infrastructure provides a high level of security for our proprietary database. The storage system for our proprietary data is designed to ensure that power and hardware failures do not result in the loss of critical data. The proprietary data is protected from unauthorized access through a combination of physical and logical security measures, including firewalls, antivirus software, anti-spy software, passwords and physical security,

44

with access limited to authorized IT personnel. In addition to our security infrastructure, our system is backed up daily to prevent the loss of our proprietary data due to catastrophic failures or natural disasters. We test our IT recovery ability semi-annually to verify that we can recover our business critical systems in a timely fashion.

Properties

Our principal executive offices are located in Chicago, Illinois. We maintain a sales office in Naperville, Illinois. We believe that our facilities are generally suitable to meet our needs for the foreseeable future; however, we continue to seek additional space as needed to satisfy our growth.

Employees

As of December 31, 2005, we had 154 employees and independent contractors, consisting of 16 corporate staff, 52 procurement managers and 86 account executives. We consider our employee relations to be good.

Legal Proceedings

We are not a party to any material pending legal proceedings.

Under our stock incentive plan, directors are eligible to receive stock option grants at the discretion of our compensation committee or other administrator of the plan.

In March 2004, we entered into an agreement with John R. Walter in connection with his election as Chairman of our Board. Under this agreement, Mr. Walter:

Ÿ purchased 100,000 shares of our common stock at a price of $0.80 per share in March 2004,

Ÿ purchased 200,000 shares of our common stock at a price of $0.80 per share in May 2005,

Ÿ received options to purchase 300,000 shares of our common stock at an exercise price of $0.50 per share in March 2004, which were fully vested upon issuance and have a term of 10 years, and

Ÿ received options to purchase an additional 900,000 shares of our common stock at an exercise price of $0.50 per share in March 2004. These options vest at the rate of 300,000 per year upon Mr. Walter’s re-election as Chairman of our Board, subject to acceleration upon the occurrence of certain events, including our completion of an initial public offering. As of March 31, 2006, 300,000 of these options were vested, and upon completion of this offering the remaining 600,000 options will vest.

In connection with the March 2004 agreement, Mr. Walter also became entitled to receive fully vested options to purchase 300,000 shares of our common stock at an exercise price of $0.50 per share, subject to our achievement of certain business and financial performance targets. In May 2006, at the request of the Company

48

and to better align the value of this equity award with the long-term interests of our stockholders, Mr. Walter agreed to eliminate his rights to these options in exchange for the grant of options to purchase 400,000 shares of our common stock at an exercise price of $4.92 per share, which was the price per share paid by SNP in April 2006. These options will vest ratably over six years at a rate of 66,666 per year. Vesting of these options will accelerate in the event of a change of control (as defined in Mr. Walter’s agreement).

In October 2005, we entered into a compensation agreement with Jack Greenberg in connection with his election to our Board. Pursuant to this agreement, we granted Mr. Greenberg options to purchase 100,000 shares of our common stock at an exercise price of $0.65 per share. These options vest in two equal installments on June 30, 2006 and 2007, provided Mr. Greenberg continues to serve on our Board on such dates. Vesting of these options will accelerate in the event of a change of control (as defined in Mr. Greenberg’s agreement).

Compensation Committee Interlocks and Insider Participation

None of the members of our compensation committee serves, or has at any time served, as an officer or employee of us or any of our subsidiaries.

Limitation of Liability and Indemnification of Officers and Directors

Our certificate of incorporation will provide that our directors and officers will be not personally liable for monetary damages to us for breaches of their fiduciary duty as directors or officers, unless they violated their duty of loyalty to us or to our stockholders, acted in bad faith, knowingly or intentionally violated the law, authorized illegal dividends or redemptions or derived an improper personal benefit from their actions as directors. Prior to the completion of this offering, we intend to obtain insurance that insures our directors and officers against specified losses. In addition, our by-laws will provide that our directors, officers and employees shall be indemnified by us to the fullest extent authorized by Delaware law, as it now exists or may in the future be amended, against all expenses and liabilities reasonably incurred by them in connection with their service for or on behalf of us.

We believe that these provisions and agreements are necessary to attract and retain qualified persons as directors and executive officers.

(1) These values were estimated using a minimum value option pricing model.

(2) 25,000 options were fully vested on July 15, 2005 and expire on July 15, 2015 and have a grant date value of $0.11 per share. 80,000 options vest in 50% annual installments beginning on October 1, 2006 and expire on October 1, 2015 and have a grant date value of $0.12 per share.

(3) 105,000 options were fully vested on July 20, 2005 and expire on July 20, 2015, with an exercise price of $1.00 per share. Because these options were granted at less than fair market value, they have no grant date value. 120,000 options vest in 33% annual installments beginning on June 20, 2006 and expire on September 19, 2015, with an exercise price of $0.65 per share and a grant date value of $0.12 per share. 100,000 options vest in a 50% installment on October 1, 2006 and a 50% installment on June 20, 2007, and expire on October 1, 2015, with an exercise price of $1.00 per share. Because these options were granted at less than fair market value, they have no grant date value.

(4) 25,000 options were fully vested on July 15, 2005 and expire on July 15, 2015 and have a grant date value of $0.11 per share. 100,000 options vest in 50% annual installments beginning on October 1, 2006 and expire on October 1, 2015 and have a grant date value of $0.12 per share.

Aggregate Option Exercises in Last Fiscal Year and Fiscal Year-End Option Values

The following table shows certain information concerning option holdings as of December 31, 2005 with respect to our named executive officers. No options were exercised by the named executive officers during the year ended December 31, 2005.

Name	Number of securities underlying unexercised options at December 31, 2005 (#)		Value of unexercised in-the-money options at December 31, 2005 (1)
	Exercisable	Unexercisable	Exercisable	Unexercisable

Mark D. Desky	55,000	30,000

(1) There was no public trading market for our common stock as of December 31, 2005. Accordingly, the value of the unexercised in-the-money options as of December 31, 2005 has been determined by calculating the difference between an assumed initial public offering price of             , the midpoint of the filing range set forth on the cover of this prospectus, and the option exercise price of each applicable in-the-money option multiplied by the number of shares underlying such option.

The option grants listed above, plus options to purchase 2,083,500 shares of common stock held by other employees, constitute all options outstanding as of December 31, 2005. We expect that options to purchase an additional 500,000 shares of common stock will be reserved for issuance under our Long-Term Incentive Plan.

Employment Agreements

Employment Agreement with Steven E. Zuccarini

We entered into an employment agreement with Steven E. Zuccarini, our Chief Executive Officer, in November 2004 and amended the agreement in May 2006. The employment agreement provides that the amount of Mr. Zuccarini’s base salary will be determined annually by our Board, but will not be less than $450,000 commencing in 2007. Also commencing in 2007, Mr. Zuccarini will receive an annual bonus of $150,000 in the event target levels of net income approved by our Board are exceeded. In addition, Mr. Zuccarini will be eligible to receive an annual bonus based on performance targets approved by our Board.

In connection with the execution of his employment agreement in November 2004, Mr. Zuccarini received options to purchase 1,500,000 shares of our common stock at an exercise price of $0.50 per share. Of these options, 300,000 vested at the time of grant and the remaining 900,000 vest ratably at the rate of 300,000 per year, subject to acceleration upon the occurrence of certain events, including our completion of an initial public offering. As of March 31, 2006, 467,167 of these options were vested, and upon the completion of this offering the remaining 900,000 options will vest.

In connection with his November 2004 employment agreement, Mr. Zuccarini also became entitled to receive fully vested options to purchase 600,000 shares of our common stock at an exercise price of $0.50 per share, subject to our achievement of certain business and financial performance targets. In May 2006, at the request of the Company and to better align the value of this equity award with the long-term interests of our stockholders, Mr. Zuccarini agreed to amend his employment agreement to eliminate his rights to these options. As part of this amendment, Mr. Zuccarini received a grant of options to purchase 750,000 shares of our common stock at an exercise price of $4.92 per share, which was the price per share paid by SNP in April 2006. These options will vest ratably over six years at a rate of 125,000 per year. Vesting of these options will accelerate in the event of a change of control (as defined in the agreement).

Mr. Zuccarini’s employment agreement may be terminated, with or without cause, by our Board. If we terminate the employment agreement for cause (as defined in the agreement) or on account of death or disability

51

or if Mr. Zuccarini terminates the agreement for any reason other than a good reason (as defined in the agreement), Mr. Zuccarini is entitled to no further compensation or benefits other than those earned through the date of termination. If we terminate the agreement for any reason other than for cause, death or disability, we will provide the following severance benefits:

Ÿ continued payment of cash compensation at a rate of $600,000 per year for two years following termination, and

Ÿ additional vesting of his options that would have otherwise vested if he had remained employed by us during the two years following the termination of his employment.

Mr. Zuccarini’s employment agreement expires in November 2012.

Employment Agreements with Other Executive Officers

In addition to our employment agreement with Mr. Zuccarini, we have entered into employment agreements with Nicholas J. Galassi, Eric D. Belcher and Scott A. Frisoni. The employment agreements generally provide for a base salary and eligibility to receive an annual performance bonus up to a specified percentage of base salary. The actual amount of the annual bonus is discretionary and determined based upon the executive’s performance, our performance and certain performance targets approved by our Board of Directors. The agreements also grant options to purchase shares of our common stock and contain customary non-competition and non-solicitation provisions.

The agreements may be terminated, with or without cause, by the executive, our Chief Executive Officer or our Board of Directors. If the executive’s employment is terminated by us for cause (as defined in the agreements), on account of death or disability or if the executive terminates his own employment for any reason other than a good reason (as defined in the agreements), the executive is entitled to no further compensation or benefits other than those earned through the date of termination. If the executive’s employment is terminated by us for any reason other than for cause, death or disability, or if the executive terminates his own employment for good reason, we will provide the following severance benefits: (i) continued payment of base salary for 12 months following termination and (ii) immediate vesting of any options that would have been exercisable in the next two years, as if the executive’s employment had continued for the two-year period.

If, during the three months prior to the public announcement of a proposed change of control (as defined in the agreements), or 12 months following a change of control, the executive’s employment is terminated by us for any reason other than cause, or terminated by the executive for good reason, the executive is generally entitled to the same benefits described above. The employment agreements with Messrs. Galassi and Frisoni expire in December 2007, and the employment agreement with Mr. Belcher expires in June 2008.

Employee Benefits Plans

2004 Unit Option Plan

Effective January 1, 2004, we adopted the InnerWorkings, LLC 2004 Unit Option Plan (the 2004 Plan). The principal purpose of the 2004 Plan has been to attract, retain and reward selected employees, consultants and directors through the granting of non-qualified stock options.

Administration.    The 2004 Plan is administered by our Board. Our officers have the authority to act on our behalf, if it is within their apparent authority, with respect to matters, rights, obligations, determinations or elections delegated to the Company under the 2004 Plan.

Grant of Options; Shares Available for Options.    Certain employees, consultants and directors are eligible to be granted awards under the plan. Our Board determines who receives options under the plan and the terms and conditions of the options consistent with the terms of the plan. Our Board has also determined the fair market value of the shares underlying options previously granted under the plan.

52

The total number of shares of our common stock available for issuance or delivery under our 2004 Plan is determined by our Board. The number of shares of our common stock issued or reserved pursuant to the 2004 Plan will be subject, at our Board’s discretion, to adjustment as a result of stock splits, stock dividends and similar changes in our common stock.

Stock Options.    The 2004 Plan permits our Board to grant participants non-qualified stock options, which do not qualify for special tax treatment in the United States. Our Board establishes the duration of each option at the time it is granted, with a maximum ten-year duration, and establishes any vesting requirements that must be met prior to the exercise of options. Stock option grants must have exercise prices that are at least equal to the fair market value of our common stock on the date of grant. Stock option grants may allow holders to pay the exercise price of the holder’s vested options by promissory note, by tendering shares of common stock already owned by the option holder for at least six months, if the stock was not acquired from the Company, or by another method approved by our Board. Stock acquired by exercise of an option granted under the 2004 Plan may be subject to a right of first refusal, repurchase options, or other conditions and restrictions determined by our Board at the time the option is granted. Upon a change in control of the Company, the acquiring company may assume the Company’s rights under the outstanding options or substitute its own securities for the Company stock underlying outstanding options.

Amendment and Termination.    Our Board may amend or terminate the 2004 Plan, but no termination or amendment will be made that adversely affects any then outstanding option or any unexercised portion thereof without the holder’s consent, other than amendments that are necessary to permit the granting of awards in compliance with applicable laws, regulations or rules.

Future Grants.    We do not intend to grant any additional options under the 2004 Plan.

Stock Incentive Plan

Prior to the completion of this offering, we expect to adopt the InnerWorkings, Inc. 2006 Stock Incentive Plan (the “Long-Term Incentive Plan”) which will replace the 2004 Plan. The principal purpose of the Long-Term Incentive Plan is to attract, motivate, reward and retain selected employees, consultants and directors through the granting of stock-based compensation awards. The Long-Term Incentive Plan will provide for a variety of awards, including non-qualified stock options, incentive stock options (within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”)), stock appreciation rights, restricted stock awards, performance-based awards and other stock-based awards.

Administration.    The Long-Term Incentive Plan is expected to be administered by our compensation committee. The committee may in certain circumstances delegate certain of its duties to one or more of InnerWorkings, Inc.’s officers. The committee has the power to interpret the Long-Term Incentive Plan and to adopt rules for the administration, interpretation and application of the plan according to its terms.

Grant of Awards; Shares Available for Awards.    Certain employees, consultants and directors are eligible to be granted awards under the plan. The committee will determine who will receive awards under the plan, as well as the form of the awards, the number of shares underlying the awards, and the terms and conditions of the awards consistent with the terms of the plan.

The total number of shares of our common stock initially available for issuance or delivery under our Long-Term Incentive Plan will be              shares. Once Section 162(m) of the Code applies, the maximum number of shares or share equivalents that may be subject to awards made to any one plan participant in any fiscal year, whether paid in shares or in cash, will be              shares. The number of shares of our common stock issued or reserved pursuant to the Long-Term Incentive Plan will be subject, at the discretion of our Board of Directors (or the committee if so empowered), to adjustment as a result of stock splits, stock dividends and similar changes in our common stock. In addition, shares subject to grant under the Company’s prior unit option plans (including shares under such plans that expire unexercised or are forfeited, terminated, canceled, or withheld for income tax withholding) shall be merged and available for issuance under the Long-Term Incentive Plan, without reducing the aggregate number of shares available for issuance listed above.

53

Stock Options.    The Long-Term Incentive Plan will permit the committee to grant participants incentive stock options, which qualify for special tax treatment in the United States, as well as non-qualified stock options. The committee will establish the duration of each option at the time it is granted, with a maximum ten-year duration for incentive stock options, and may also establish vesting and performance requirements that must be met prior to the exercise of options. Stock option grants (other than incentive stock option grants) also may have exercise prices that are less than, equal to or greater than the fair market value of our common stock on the date of grant. Incentive stock options must have an exercise price that is at least equal to the fair market value of our common stock on the date of grant. Stock option grants may include provisions that permit the option holder to exercise all or part of the holder’s vested options, or to satisfy withholding tax liabilities, by tendering shares of common stock already owned by the option holder for at least six months (or another period consistent with the applicable accounting rules) with a fair market value equal to the exercise price. We expect options to purchase 500,000 shares of our common stock will be allocated for grant under this plan.

Stock Appreciation Rights.    The committee may also grant stock appreciation rights, which will be exercisable upon the occurrence of certain contingent events. Stock appreciation rights entitle the holder upon exercise to receive an amount in any combination of cash, shares of our common stock (as determined by the committee) equal in value to the excess of the fair market value of the shares covered by the right over the exercise price of the stock appreciation right, or other securities or property of the Company.

Other Equity-Based Awards.    In addition to stock options and stock appreciation rights, the committee may also grant to certain employees, consultants and directors shares of restricted stock, restricted stock rights, dividend equivalents, performance-based awards or other stock-based awards, with terms and conditions as the committee may, pursuant to the terms of the Long-Term Incentive Plan, establish. The Long-Term Incentive Plan also allows awards to be made in conjunction with a participant’s election to defer compensation in accordance with the rules of Section 409A of the Code.

Change-in-Control Provisions.    In connection with the grant of an award, the committee if so empowered, may provide that, in the event of a change in control of the Company, any outstanding awards that are unexercisable or otherwise unvested will become fully vested and immediately exercisable.

Amendment and Termination.    The committee may adopt, amend and rescind rules relating to the administration of the Long-Term Incentive Plan, and amend, suspend or terminate the Long-Term Incentive Plan, but no amendment will be made that adversely affects in a material manner any rights of the holder of any award without the holder’s consent, other than amendments that are necessary to permit the granting of awards in compliance with applicable laws. We have attempted to structure the Long-Term Incentive Plan so that remuneration attributable to stock options and other awards will not be subject to a deduction limitation contained in Section 162(m) of the Code.

Annual Incentive Plan

We have adopted the InnerWorkings Annual Incentive Plan (the “Annual Incentive Plan”) that rewards employees for meeting and exceeding annual performance goals established by the compensation committee based on one or more criteria set forth in the Annual Incentive Plan.

Eligibility to participate in the Annual Incentive Plan is limited to substantially all regular full-time and part-time employees. Temporary employees, any independent contractors, and certain other specified classifications are not eligible to participate in the Annual Incentive Plan.

Employees are eligible to receive bonuses based on meeting operational and financial goals that may be stated (a) as goals of the company, a subsidiary, or a portion thereof, (b) on an absolute basis and/or relative to other companies, or (c) separately for one or more participants or business units. The objective performance goals for the Annual Incentive Plan are established by our compensation committee at the beginning of the year. Bonus payouts are determined within a reasonable time after the end of the performance period.

54

Upon the completion of this offering, our compensation committee will administer the Annual Incentive Plan and will have the authority to construe, interpret and implement the Annual Incentive Plan and prescribe, amend and rescind rules and regulations relating to the Annual Incentive Plan. The determination of the compensation committee on all matters relating to the Annual Incentive Plan or any award agreement will be final, binding and conclusive. The Annual Incentive Plan may be amended or terminated by the committee or our Board of Directors.

DESCRIPTION OF CAPITAL STOCK

General

Upon the closing of this offering, the total amount of our authorized capital stock will consist of              shares of common stock, $0.0001 par value, and              shares of preferred stock, $0.0001 par value. We intend to adopt, and intend to submit for approval by our stockholders, a recapitalization agreement, a second amended and restated certificate of incorporation and amended and restated by-laws to become effective immediately prior to the closing of this offering. We also intend to consummate a     :     stock split of our common stock immediately following the recapitalization and immediately prior to the closing of this offering. The discussion herein describes the recapitalization and also describes our capital stock, second amended and restated certificate of incorporation and amended and restated by-laws as anticipated to be in effect upon the closing of this offering. The following summary of certain provisions of our capital stock describes certain material provisions of, but does not purport to be complete and is subject to and qualified in its entirety by, our second amended and restated certificate of incorporation and amended and restated by-laws, which are included as exhibits to the registration statement of which this prospectus forms a part, and by the provisions of applicable law.

Recapitalization

Prior to the completion of this offering, each outstanding share of our capital stock will be reclassified and converted into one share of our common stock. Additionally, immediately prior to the closing of this offering, each outstanding option will be converted into an option to receive one share of common stock upon the applicable exercise date. Immediately following the recapitalization and immediately prior to the closing of this offering, we intend to consummate a     :     stock split of our common stock.

Common Stock

Following the recapitalization and the stock split, and immediately prior to the closing of this offering, there will be              shares of common stock outstanding held by          holders of record. Holders of common stock are entitled to one vote for each share held on all matters subject to a vote of stockholders, subject to the rights of holders of any outstanding preferred stock, and have cumulative voting rights. Accordingly, holders of a majority of the shares of common stock entitled to vote in any election of directors may elect all of the directors standing for election, subject to the rights of holders of any outstanding preferred stock. Holders of common stock will be entitled to receive ratably any dividends that the board of directors may declare out of funds legally available therefor, subject to any preferential dividend rights of outstanding preferred stock. Upon our liquidation, dissolution or winding up, the holders of common stock will be entitled to receive ratably our net assets available after the payment of all debts and other liabilities and subject to the prior rights of holders of any outstanding preferred stock. Holders of common stock have no preemptive, subscription, redemption or conversion rights. There will be no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of our capital stock are fully paid and nonassessable, and the shares of common stock to be issued on completion of this offering will be fully paid and nonassessable.

Preferred Stock

Following the recapitalization and immediately prior to the closing of this offering, we will be authorized to issue              shares of preferred stock, which may be issued from time to time in one or more series upon authorization by the Board of Directors. The Board of Directors, without further approval of the stockholders, will be authorized to fix the number of shares constituting any series, as well as the dividend rights and terms, conversion rights and terms, voting rights and terms, redemption rights and terms, liquidation preferences and any other rights, preferences, privileges and restrictions applicable to each series of preferred stock. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could also adversely affect the voting power and dividend and liquidation rights of the holders of common stock. The issuance of preferred stock could also, under some circumstances, have the effect of making

62

it more difficult for a third party to acquire, or discouraging a third party from acquiring, a majority of our outstanding voting stock or otherwise adversely affect the market price of our common stock. It is not possible to state the actual effect of the issuance of any shares of preferred stock on the rights of holders of common stock until the Board of Directors determines the specific rights of that series of preferred stock.

Registration Rights

Upon the completion of this offering, the former holders of our Series B, D and E preferred shares, who will own approximately                  shares of our common stock, will have the right to require us to register the resale of their shares under the Securities Act pursuant the terms of an investor rights agreement between us and these holders. Subject to limitations specified in the agreement, these registration rights include the following:

Demand Registration Rights.    If the former holders of our Series E preferred shares request that we register all or a portion of their shares, we are also required to register, upon request, the shares held by the former holders of our Series B and D preferred shares, subject to limitations that the underwriters may impose on the number of shares included in the registration. We are only required to file two registration statements upon the stockholders’ exercise of these demand registration rights. We will not be required to effect a demand registration during the period starting with the date of filing, and ending 180 days following the effective date of, this registration statement.

Piggyback Registration Rights.    If we propose to file a registration statement under the Securities Act to register our shares of common stock, the former holders of our Series B, D and E preferred shares are entitled to notice of such registration and have the right, subject to limitations that the underwriters may impose on the number of shares included in the registration, to include their shares in the registration. These rights have been waived with respect to this offering. The holders of our Series B, D and E preferred shares also have the right to include their shares in our future registrations, including secondary offerings of our common stock.

Form S-3 Registration Rights.    If we become eligible to file registration statements on Form S-3, the former holders of our Series B, D and E preferred shares can require us to register their shares on Form S-3 if the aggregate offering price to the public is at least $1.0 million. We will not be required to effect more than two registrations on Form S-3 in any given calendar year, and are not required to effect a registration on a Form S-3 during the period beginning 30 days prior to, and 90 days following, any public offering of our common stock, subject to certain exceptions.

Expenses of Registration.    With specified exceptions, we are required to pay all expenses of registration, including the fees and expenses of one legal counsel to the holders up to a prescribed maximum amount, but excluding underwriters’ discounts and commissions.

Right of First Refusal.    Each party to the investor rights agreement has a right of first refusal to purchase its pro rata share of certain of our equity securities. These rights do not apply to this offering and terminate immediately upon the effective date of this registration statement.

The registration rights described above will terminate, with respect to any particular stockholder, upon the earlier of (i) an acquisition of us under certain circumstances or (ii) three years after the completion of this offering. Each party to the investor rights agreement has agreed not to sell or otherwise dispose of any shares of our common stock for a period of 180 days following the effective date of this offering.

Elimination of Liability in Certain Circumstances

Our certificate of incorporation will eliminate the liability of our directors to us or our stockholders for monetary damages resulting from breaches of their fiduciary duties as directors. Directors will remain liable for breaches of their duty of loyalty to us or our stockholders, as well as for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, and transactions from which a director derives

63

improper personal benefit. Our articles of incorporation will not absolve directors of liability for payment of dividends or stock purchases or redemptions by us in violation of Section 174 (or any successor provision of the Delaware General Corporation Law.

The effect of this provision is to eliminate the personal liability of directors for monetary damages for actions involving a breach of their fiduciary duty of care, including any such actions involving gross negligence. We believe that this provision does not eliminate the liability of our directors to us or our shareholders for monetary damages under the federal securities laws. The articles of incorporation and by-laws will also provide indemnification for the benefit of our directors and officers to the fullest extent permitted by the Delaware General Corporation Law as it may be amended from time to time, including most circumstances under which indemnification otherwise would be discretionary.

Number of directors; Removal; Vacancies

Our by-laws will provide that we have seven directors, provided that this number may be changed by the board of directors. Vacancies on the board of directors may be filled only by the affirmative vote of a majority of the remaining directors then in office. Our by-laws provide that directors may be removed, with or without cause, at meetings of stockholders by the affirmative vote of the holders of a majority of the outstanding shares entitled to vote generally in the election of directors.

Special Meetings of Stockholders

Our by-laws will provide that special meetings of our stockholders may be called only by our chairman of the board, our chief executive officer, our board of directors, or holders of not less than a majority of all the outstanding shares entitled to vote on the matter for which the meeting is being called or the purpose or purposes stated in the meeting notice.

Amendments; Vote Requirements

Our certificate of incorporation and by-laws will provide that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation or by-laws, including those provisions relating to action by written consent and the ability of stockholders to call special meetings.

Authorized but Unissued Shares

The authorized but unissued shares of common stock are available for future issuance without stockholder approval. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions, and employee benefit plans. The existence of authorized but unissued shares of common stock could render it more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Advance notice requirements for stockholder proposals and nomination of directors

Our by-laws will provide that stockholders seeking to bring business before an annual meeting of stockholders, or to nominate candidates for election as directors at an annual meeting of stockholders, must provide timely notice in writing. To be timely, a stockholder’s notice must be delivered to or mailed and received at our principal executive offices not less than 60 days nor more than 90 days prior to the anniversary date of the immediately preceding annual meeting of stockholders. However, in the event that the annual meeting is called for a date that is not within 30 days before or after such anniversary date, such notice will be timely only if received not later than the close of business on the tenth day following the date on which notice of the date of the annual meeting was mailed to stockholders or made public, whichever first occurs. Our by-laws will also specify requirements as to the form and content of a stockholder’s notice.

Our officers and directors and our other stockholders, who will hold an aggregate of                  shares of common stock upon completion of this offering, have agreed that they will not, without the prior written consent of Morgan Stanley, offer, sell, pledge or otherwise dispose of any shares of our common stock or any securities convertible into or exercisable or exchangeable for, or any rights to acquire or purchase, any of our common stock, or publicly announce an intention to effect any of these transactions, for a period of 180 days (subject to extensions) after the date of this prospectus without the prior written consent of Morgan Stanley, except that nothing will prevent any of them from exercising outstanding options and warrants. These lock-up agreements are subject to such stockholders’ rights to transfer their shares of common stock as a bona fide gift or to a trust for the benefit of an immediate family member or to an affiliate, provided that such donee or transferee agrees in writing to be bound by the terms of the lock-up agreement.

Taking into account the lock-up agreements, and assuming Morgan Stanley does not release stockholders from these agreements, the following shares will be eligible for sale in the public market at the following times:

Ÿ on the date of this prospectus, the                  shares sold in this offering will be immediately available for sale in the public market;

Ÿ 180 days after the date of this prospectus,                  shares will be eligible for sale,                  of which will be subject to volume, manner of sale and other limitations under Rule 144; and

Ÿ the remaining                  shares will be eligible for sale under Rule 144 from time to time upon the expiration of various one-year holding periods.

Shares issuable upon exercise of options we granted prior to the date of this prospectus will also be available for sale in the public market pursuant to Rule 701 under the Securities Act, subject to certain Rule 144 limitations and, in the case of some holders, to the lock-up agreements. Rule 701 permits resales of these shares beginning 90 days after the date of this prospectus by persons other than affiliates.

In general, under Rule 144, a stockholder who owns restricted shares that have been outstanding for at least one year is entitled to sell, within any three-month period, a number of these restricted shares that does not exceed the greater of:

Ÿ one percent of the then outstanding shares of common stock, or approximately                  shares immediately after this offering; or

Ÿ the average weekly trading volume in the common stock on the Nasdaq National Market during the four calendar weeks preceding the sale.

66

Our affiliates must comply with the restrictions and requirements of Rule 144, other than the one-year holding period requirement, to sell shares of common stock which are not restricted securities.

Under Rule 144(k), a stockholder who is not currently, and who has not been for at least three months before the sale, an affiliate of ours and who owns restricted shares that have been outstanding for at least two years may resell these restricted shares without compliance with the above requirements. The one- and two-year holding periods described above do not begin to run until the full purchase price is paid by the person acquiring the restricted shares from us or an affiliate of ours.

CERTAIN MATERIAL U.S. FEDERAL INCOME TAX

CONSEQUENCES TO NON-U.S. HOLDERS

The following summary describes certain material United States federal income tax consequences of the ownership and disposition of common stock by a Non-U.S. Holder (as defined below) holding shares of our common stock as capital assets (i.e., generally for investment) as of the date of this prospectus. This discussion does not address all aspects of United States federal income taxation and does not deal with estate, gift, foreign, state and local tax consequences that may be relevant to such Non-U.S. Holders in light of their personal circumstances. Special U.S. tax rules may apply to certain Non-U.S. Holders, such as “controlled foreign corporations,” “passive foreign investment companies,” corporations that accumulate earnings to avoid U.S. federal income tax, investors in partnerships or other pass-through entities for U.S. federal income tax purposes, dealers in securities, holders of securities held as part of a “straddle,” “hedge,” “conversion transaction” or other risk reduction transaction, and certain former citizens or long-term residents of the United States that are subject to special treatment under the Code. Such entities and persons should consult their own tax advisors to determine the U.S. federal, state, local and other tax consequences that may be relevant to them. Furthermore, the discussion below is based upon the provisions of the Code, and Treasury regulations promulgated thereunder, rulings and judicial decisions thereunder as of the date hereof, and such authorities may be repealed, revoked or modified with or without retroactive effect so as to result in United States federal income tax consequences different from those discussed below.

If a partnership (or an entity treated as a partnership for U.S. federal income tax purposes) holds the common stock, the tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Persons who are partners in partnerships holding the common stock should consult their tax advisors.

The authorities on which this summary is based are subject to various interpretations, and any views expressed within this summary are not binding on the Internal Revenue Service (which we also refer to as the IRS) or the courts. No assurance can be given that the IRS or the courts will agree with the tax consequences described in this prospectus.

As used herein, a “Non-U.S. Holder” means a beneficial owner of our common stock that is not any of the following for U.S. federal income tax purposes:

Ÿ a citizen or resident of the United States,

Ÿ a corporation, or other entity treated as a corporation for United States federal income tax purposes, created or organized in or under the laws of the United States, any state thereof or the District of Columbia,

Ÿ an estate the income of which is subject to United States federal income taxation regardless of its source, or

Ÿ a trust (i) which is subject to primary supervision by a court situated within the United States and as to which one or more United States persons have the authority to control all substantial decisions of the trust, or (ii) that has a valid election in effect under applicable U.S. Treasury regulations to be treated as a United States person.

Prospective purchasers are urged to consult their own tax advisors regarding the U.S. federal income tax consequences, as well as other U.S. federal, state, and local income and estate tax consequences, and non-U.S. tax consequences, to them of acquiring, owning, and disposing of our common stock.

Dividends

If we make distributions on our common stock, such distributions paid to a Non-U.S. Holder will generally constitute dividends for U.S. federal income tax purposes to the extent such distributions are paid from our

68

current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds our current and accumulated earnings and profits, the excess will be treated as a tax-free return of the Non-U.S. Holder’s investment to the extent of the Non-U.S. Holder’s adjusted tax basis in our common stock. Any remaining excess will be treated as capital gain. See “— Gain on Disposition of Common Stock” for additional information.

Dividends paid to a Non-U.S. Holder generally will be subject to withholding of United States federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. A Non-U.S. Holder of common stock who wishes to claim the benefit of an applicable treaty rate for dividends will be required to (a) complete IRS Form W-8BEN (or appropriate substitute form) and certify, under penalty of perjury, that such holder is not a U.S. person and is eligible for the benefits with respect to dividends allowed by such treaty or (b) hold common stock through certain foreign intermediaries and satisfy the certification requirements for treaty benefits of applicable Treasury regulations. Special certification requirements apply to certain Non-U.S. Holders that are “pass-through” entities for U.S. federal income tax purposes. A Non-U.S. Holder eligible for a reduced rate of United States withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

This United States withholding tax generally will not apply to dividends that are effectively connected with the conduct of a trade or business by the Non-U.S. Holder within the United States, and, if a treaty applies, attributable to a United States permanent establishment or fixed base of the Non-U.S. Holder. Dividends effectively connected with the conduct of a trade or business, as well as those attributable to a United States permanent establishment or fixed base of the Non-U.S. Holder under an applicable treaty, are subject to United States federal income tax generally in the same manner as if the Non-U.S. Holder were a U.S. person, as defined under the Code. Certain IRS certification and disclosure requirements must be complied with in order for effectively connected dividends to be exempt from withholding. Any such effectively connected dividends received by a Non-U.S. Holder that is a foreign corporation may, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

Gain on Disposition of Common Stock

A Non-U.S. Holder generally will not be subject to United States federal income tax (or any withholding thereof) with respect to gain recognized on a sale or other disposition of common stock unless:

Ÿ the gain is effectively connected with a trade or business of the Non-U.S. Holder in the United States and, where a tax treaty applies, is attributable to a United States permanent establishment or fixed base of the Non-U.S. Holder,

Ÿ the Non-U.S. Holder is an individual who is present in the United States for 183 or more days during the taxable year of disposition and meets certain other requirements, or

Ÿ we are or have been a “U.S. real property holding corporation” within the meaning of Section 897(c)(2) of the Code, also referred to as a USRPHC, for United States federal income tax purposes at any time within the five-year period preceding the disposition (or, if shorter, the Non-U.S. Holder’s holding period for the common stock).

Gain recognized on the sale or other disposition of common stock and effectively connected with a United States trade or business, or attributable to a United States permanent establishment or fixed base of the Non-U.S. Holder under an applicable treaty, is subject to United States federal income tax on a net income basis generally in the same manner as if the Non-U.S. Holder were a U.S. person, as defined under the Code. Any such effectively connected gain from the sale or disposition of common stock received by a Non-U.S. Holder that is a foreign corporation may, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

69

An individual Non-U.S. Holder who is present in the United States for 183 or more days during the taxable year of disposition generally will be subject to a 30% tax imposed on the gain derived from the sale or disposition of our common stock, which may be offset by U.S. source capital loses realized in the same taxable year.

In general, a corporation is a USRPHC if the fair market value of its “U.S. real property interests” equals or exceeds 50% of the sum of the fair market value of its worldwide (domestic and foreign) real property interest and its other assets used or held for use in a trade or business. For this purpose, real property interests include land, improvements and associated personal property.

We believe that we currently are not a USRPHC. In addition, based on these financial statements and current expectations regarding the value and nature of our assets and other relevant data, we do not anticipate becoming a USRPHC.

If we become a USRPHC, a Non-U.S. Holder nevertheless will not be subject to United States federal income tax if our common stock is regularly traded on an established securities market, within the meaning of applicable Treasury regulations, and the Non-U.S. Holder holds no more than five percent of our outstanding common stock, directly or indirectly, during the applicable testing period. Our common stock has been approved for quotation on the Nasdaq National Market and we expect that our common stock may be regularly traded on an established securities market in the United States so long as it is so quoted.

Information Reporting and Backup Withholding

We must report annually to the IRS and to each Non-U.S. Holder the amount of dividends paid to such holder and the tax withheld with respect to such dividends, regardless of whether withholding was required. Copies of the information returns reporting such dividends and withholding may also be made available to the tax authorities in the country in which the Non-U.S. Holder resides under the provisions of an applicable income tax treaty.

The United States imposes a backup withholding tax on dividends and certain other types of payments to United States persons (currently at a rate of 28%) of the gross amount. Dividends paid to a Non-U.S. Holder will not be subject to backup withholding if proper certification of foreign status (usually on an IRS Form W-8BEN) is provided, and the payor does not have actual knowledge or reason to know that the beneficial owner is a United States person, or the holder is a corporation or one of several types of entities and organizations that qualify for exemption, also referred to as an exempt recipient.

Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against such holder’s U.S. federal income tax liability provided the required information is timely furnished to the IRS.

UNDERWRITING

Under the terms and subject to the conditions in an underwriting agreement dated the date of this prospectus, the underwriters named below, for whom Morgan Stanley & Co. Incorporated is acting as representative, have severally agreed to purchase, and we and the selling stockholders have agreed to sell to them, severally, the number of shares indicated below:

Name	Number of Shares
Morgan Stanley & Co. Incorporated
Jefferies Broadview
Piper Jaffray & Co.
William Blair & Company, L.L.C.
Total

The underwriters and the representative are collectively referred to as the “underwriters” and the “representative,” respectively. The underwriters are offering the shares of common stock subject to their acceptance of the shares from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the shares of common stock offered by this prospectus are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the shares of common stock offered by this prospectus if any such shares are taken. However, the underwriters are not required to take or pay for the shares covered by the underwriters’ over-allotment option described below.

The underwriters initially propose to offer part of the shares of common stock directly to the public at the offering price listed on the cover page of this prospectus and part to certain dealers. After the initial offering of the shares of common stock, the offering price and other selling terms may from time to time be varied by the representative.

The selling stockholders have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus, to purchase up to                  additional shares of common stock at the public offering price listed on the cover page of this prospectus, less underwriting discounts and commissions. The underwriters may exercise this option solely for the purpose of covering over-allotments, if any, made in connection with the offering of the shares of common stock offered by this prospectus. To the extent the option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the additional shares of common stock as the number listed next to the underwriter’s name in the preceding table bears to the total number of shares of common stock listed next to the names of all underwriters in the preceding table.

The following table shows the per share and total public offering price, underwriting discounts and commissions, and proceeds before expenses to us and the selling stockholders. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase up to an additional                  shares of common stock.

	Per Share	No Exercise	Full Exercise
Public offering price	$	$	$
Underwriting discounts and commissions to be paid by:
Us

Proceeds, before expenses, to us
Proceeds, before expenses, to the selling stockholders

The estimated offering expenses payable by us, exclusive of the underwriting discounts and commissions, are approximately $                .

71

The underwriters have informed us that they do not intend sales to discretionary accounts to exceed 5% of the total number of shares of common stock offered by them.

We have applied to list our common shares for quotation on the Nasdaq National Market under the symbol “INWK.”

We and all directors and officers and the holders of all of our outstanding stock and stock options have agreed that, without the prior written consent of Morgan Stanley & Co. Incorporated on behalf of the underwriters, we and they will not, during the period ending 180 days after the date of this prospectus:

Ÿ offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase lend or otherwise transfer or dispose of, directly or indirectly, any shares of common stock or any securities convertible into or exercisable or exchangeable for shares of common stock;

Ÿ file any registration statement with the Securities and Exchange Commission relating to the offering of any shares of common stock or any securities convertible into or exercisable or exchangeable for common stock; or

Ÿ enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the common stock.

whether any such transaction described above is to be settled by delivery of common stock or such other securities, in cash or otherwise. In addition, we and each such person agrees that, without the prior written consent of Morgan Stanley & Co. Incorporated on behalf of the underwriters, it will not, during the period ending 180 days after the date of this prospectus, make any demand for, or exercise any right with respect to, the registration of any shares of common stock or any security convertible into or exercisable or exchangeable for common stock.

The restrictions described in the immediately preceding paragraph to do not apply to:

Ÿ the sale of shares to the underwriters;

Ÿ the grant of options or the issuance of shares of common stock pursuant to any employee benefit plan described in this prospectus;

Ÿ the filing with the Securities and Exchange Commission of any registration statement on Form S-8 in respect of any employee benefit plan described in this prospectus;

Ÿ transactions by a selling stockholder relating to shares of common stock or other securities acquired in open market transactions after the completion of the offering of the shares;

Ÿ transfers of shares of common stock or any security convertible into common stock as a bona fide gift;

Ÿ transfers of shares of common stock to any trust, partnership or limited liability company for the direct or indirect benefit of the signer or the immediate family of the signer;

Ÿ transfers of shares of common stock to any beneficiary of the signer pursuant to a will or other testamentary document or applicable laws of descent;

Ÿ transfers of shares of common stock or any securities convertible into or exercisable or exchangeable for common stock to the company;

Ÿ distributions of shares of common stock or any security convertible into common stock to limited partners or stockholders of the signer; or

Ÿ transfers of shares of common stock to any wholly-owned subsidiary of the signer or to the parent corporation of the signer or any wholly-owned subsidiary of the signer or to the parent corporation of the signer or any wholly-owned subsidiary of such parent corporation;

72

provided that in the case of any of the last seven bullets, (i) each donee distributee or transferee shall sign and deliver a lock-up agreement and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of shares of common stock, shall be required or shall be voluntarily made in connection with such transfer or distribution during the 180 day period (including extensions).

The 180 day restricted period described in the preceding paragraph will be extended if:

Ÿ during the last 17 days of the 180 day restricted period we issue an earnings release or material news event relating to us occurs, or

Ÿ prior to the expiration of the 180 day restricted period, we announce that we will release earnings results during the 16 day period beginning on the last day of the 180 day period,

in which case the restrictions described in the preceding paragraph will continue to apply until the expiration of the 18 day period beginning on the issuance of the earnings release or the occurrence of material news or a material event.

In order to facilitate the offering of the common stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the common stock. Specifically, the underwriters may sell more shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of shares available for purchase by the underwriters under the over-allotment option. The underwriters can close out a covered short sale by exercising the over-allotment option or purchasing shares in the open market. In determining the source of shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under the over-allotment option. The underwriters may also sell shares in excess of the over-allotment option, creating a naked short position. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, shares of common stock in the open market to stabilize the price of the common stock. These activities may raise or maintain the market price of the common stock above independent market levels or prevent or retard a decline in the market price of the common stock. The underwriters are not required to engage in these activities and may end any of these activities at any time.

We, the selling stockholders and the underwriters have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

A prospectus in electronic format may be made available on websites maintained by one or more underwriters, or selling group members, if any, participating in this offering. The representative may agree to allocate a number of shares of common stock to underwriters for sale to their online brokerage account holders. Internet distributions will be allocated by the representative to underwriters that may make Internet distributions on the same basis as other allocations.

European Economic Area

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive, each underwriter has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Member State it has not made and will not make an offer of shares to the public in that Member State, except that it may, with effect from and including such date, make an offer of shares to the public in that Member State:

(a) at any time to legal entities which are authorised or regulated to operate in the financial markets or, if not so authorised or regulated, whose corporate purpose is solely to invest in securities;

73

(b) at any time to any legal entity which has two or more of (1) an average of at least 250 employees during the last financial year; (2) a total balance sheet of more than €43,000,000 and (3) an annual net turnover of more than €50,000,000, as shown in its last annual or consolidated accounts; or

(c) at any time in any other circumstances which do not require the publication by us of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of the above, the expression an “offer of shares to the public” in relation to any shares in any Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the shares to be offered so as to enable an investor to decide to purchase or subscribe the shares, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression Prospectus Directive means Directive 2003/71/EC and includes any relevant implementing measure in that Member State.

United Kingdom

Each underwriter has represented and agreed that it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets Act 2000) in connection with the issue or sale of the shares in circumstances in which Section 21(1) of such Act does not apply to us and it has complied and will comply with all applicable provisions of such Act with respect to anything done by it in relation to any shares in, from or otherwise involving the United Kingdom.

Pricing of the Offering

Prior to this offering, there has been no public market for our common stock. The initial public offering price was determined by negotiations between us and the representative. Among the factors considered in determining the initial public offering price were our future prospects and those of our industry in general, our sales, earnings and certain other financial and operating information in recent periods, and the price-earnings ratios, price-sales ratios, market prices of securities, and certain financial and operating information of companies engaged in activities similar to ours.

Directed Share Program

At our request, the underwriters have reserved              percent of the shares of common stock offered by this prospectus for sale, at the initial public offering price, to directors, officers, employees, business associates and related persons of InnerWorkings, Inc. If purchased by these persons, these shares will be subject to a 180-day lock-up restriction. The number of shares of common stock available for sale to the general public will be reduced to the extent these individuals purchase such reserved shares. Any reserved shares that are not so purchased will be offered by the underwriters to the general public on the same basis as the other shares offered by this prospectus.

Other Relationships

Certain of the underwriters or their affiliates may provide in the future financial advisory services to us in the ordinary course of business, for which they may receive customary fees and commissions.

Report of Independent Registered Public Accounting Firm

The Members

InnerWorkings, LLC and Subsidiary

We have audited the accompanying consolidated balance sheets of InnerWorkings, LLC and Subsidiary as of December 31, 2005 and 2004, and the related consolidated statements of operations, members’ equity, and cash flows for each of the three years in the period ended December 31, 2005. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. We were not engaged to perform an audit of the Company’s internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of InnerWorkings, LLC and Subsidiary as of December 31, 2005 and 2004, and the results of their operations and their cash flows for each of the three years in the period ended December, 31, 2005, in conformity with U.S. generally accepted accounting principles.

The foregoing report is the form that will be signed upon the completion of the common stock split described in “stock split” section of Note 2 in the consolidated financial statements.

InnerWorkings, LLC and Subsidiary

Notes to Consolidated Financial Statements

December 31, 2005, 2004, and 2003

1. Description of the Business

InnerWorkings, LLC (IW or the Company) is majority owned by InCorp LLC. The Company is a leading provider of print procurement services to large and middle market companies in the United States. The Company’s services range from procuring, purchasing and delivering print products in individual transactions through a competitive bid process to offering comprehensive outsourced enterprise solutions.

In January 2003, the Company acquired all outstanding member units of Insight World Group (IWG) from its controlling member. Subsequent to the acquisition, certain intangible assets of Express Productions, Inc. (see Note 7) were acquired by IWG in exchange for a 49% ownership interest resulting from recently issued member units of IWG. In March 2005, the Company purchased the remaining 49% interest in IWG in exchange for 150,000 options to purchase Class A common nonvoting units in IW at an exercise price of $.50 per unit. The consolidated financial statements include the results of IWG from the date of acquisition.

The Company is organized pursuant to the Delaware Limited Liability Company Act, which limits the liability of the individual members. The term of existence began with the filing of the Certificate of Formation with the Delaware Secretary of State and continues indefinitely.

2. Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of IW and its subsidiary, IWG. All significant intercompany accounts and transactions have been eliminated in the consolidation.

Use of Estimates

The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Revenue Recognition

Revenue is recognized when the product is shipped from a third party to the customer, which is when title transfers. Unbilled revenue relates to shipments that have been made to customers for which the related account receivable has not yet been billed.

Cash and Cash Equivalents

For purposes of the consolidated statements of cash flows, the Company considers all highly liquid investments purchased with a maturity of three months or less to be cash equivalents.

Accounts Receivable

Accounts receivable are uncollateralized customer obligations due under normal trade terms. Invoices require payment within 30 to 60 days from the invoice date. Accounts receivable are stated at the amount billed

F-7

InnerWorkings, LLC and Subsidiary

Notes to Consolidated Financial Statements—(Continued)

to the customer. Customer account balances with invoices dated over 90 days old are considered delinquent. Interest is not accrued on outstanding balances.

The carrying amount of accounts receivable is reduced by a valuation allowance that reflects management’s best estimate of the amounts that will not be collected. Management individually reviews all accounts receivable balances and, based on an assessment of current creditworthiness, estimates the portion, if any, of the balance that will not be collected. Fully reserved receivables are reviewed on a monthly basis and uncollectible accounts are written off when all reasonable collection efforts have been exhausted.

Property and Equipment

Property and equipment are stated at cost. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. The estimated useful lives, by asset class, are as follows:

Computer equipment and software	3 years
Furniture and fixtures	5 years

Goodwill and Other Intangibles

Goodwill represents the excess of purchase price and related costs over the value assigned to the net tangible and identifiable intangible assets of businesses acquired. In accordance with Statement of Financial Accounting Standards (SFAS) No. 142, Goodwill and Other Intangible Assets, goodwill is not amortized, but instead is tested for impairment annually, or more frequently if circumstances indicate a possible impairment may exist. The Company evaluates the recoverability of goodwill using a two-step impairment test. For goodwill impairment review purposes, the Company has one reporting unit. In the first step, the fair value for the Company is compared to its book value including goodwill. In the case that the fair value is less than the book value, a second step is performed which compares the implied fair value of goodwill to the book value of the goodwill. The fair value for the goodwill is determined based on the difference between the fair values and the net fair values of the identifiable assets and liabilities. If the implied fair value of the goodwill is less than the book value, the difference is recognized as an impairment.

SFAS No. 142 also requires that intangible assets with finite lives be amortized over their respective estimated useful lives and reviewed for impairment in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. The Company’s intangible assets consist of customer lists and noncompete agreements, which are being amortized on the straight-line basis over their estimated useful lives of ten years and five years, respectively.

Following is a summary of the intangible assets as of December 31:

	2004			2005			Weighted- Average Life
Customer lists	$	646,500		$	925,485		9.7 years
Noncompete agreement		242,000			242,000		5 years
		888,500			1,167,485
Less accumulated amortization		(98,351	)		(236,711	)
Intangible assets, net	$	790,149		$	930,774

Amortization expense related to these intangible assets was $138,360 and $98,351 for the years ended December 31, 2005 and 2004, respectively.

InnerWorkings, LLC and Subsidiary

Notes to Consolidated Financial Statements—(Continued)

The estimated amortization expense for the next five years is as follows:

2006	$	155,949
2007		137,199
2008		137,199
2009		100,899
2010		88,799
Thereafter		310,729
	$	930,774

Shipping and Handling Costs

Shipping and handling costs are classified in cost of sales in the consolidated statements of operations.

Investment

Investment consists of an investment in an affiliated company that IW does not control and does not have the ability to exercise significant influence over such affiliated companies’ operations and financial policies. This investment is accounted for using the cost method.

Income Taxes

Through December 31, 2005, IW and its subsidiary are treated as partnerships for federal income tax purposes. Federal taxes are not payable by or provided for the companies. Members are taxed individually on their share of each of the Company’s earnings.

On January 3, 2006, as discussed in Note 18, IW converted from an LLC to a “C” corporation. In connection with this conversion, the Company will account for income taxes in accordance with SFAS No. 109, Accounting for Income Taxes (SFAS No. 109), under which deferred assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between financial statement carrying values of assets and liabilities and their respective tax bases. A valuation allowance is established to reduce the carrying value of deferred tax assets if it is considered more likely than not that such assets will not be realized. Any change in the valuation allowance would be charged to income in the period such determination was made. For informational purposes, the statements of operations include a pro forma adjustment for income taxes that would have been recorded if the Company was a “C” corporation, calculated in accordance with SFAS No. 109.

Advertising

Costs of advertising, which are expensed as incurred by the Company, were $81,298, $31,770, and $49,807 for each of the years ended December 31, 2005, 2004, and 2003, respectively.

Stock-Based Compensation

The Company accounts for stock-based employee compensation arrangements in accordance with provisions of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and complies with the disclosure requirements of Financial Accounting Standards Board (FASB) No. 148, Accounting for Stock-Based Compensation—Transition and Disclosure—An Amendment of FASB Statement No. 123. Under APB No. 25, compensation expense is based on the difference, if any, on the grant date between

F-9

InnerWorkings, LLC and Subsidiary

Notes to Consolidated Financial Statements—(Continued)

the estimated fair value of the Company’s stock and the exercise price of options to purchase that stock. The compensation expense is then amortized over the vesting period of the stock options.

To value option grants in accordance with SFAS No. 123, the Company used the minimum value method. Net income on a pro forma basis, if compensation expense for employee option-based awards were determined using the minimum value method, is as follows:

	Years Ended December 31,
	2004		2005
Net income, as reported	$	1,756,810	$	4,634,137
Pro forma adjustment – net of tax:
Stock-based compensation, included in net income		—		87,500
Minimum value compensation expense		—		(158,160	)
Pro forma net income	$	1,756,810	$	4,563,477
Net income per share, as reported:

Diluted	$	0.04	$	0.12
Pro forma net income per share:
Basic	$	0.04	$	0.12
Diluted	$	0.04	$	0.12

To value option grants in accordance with SFAS No. 123, the Company used the minimum value method. The minimum values of the options issued were immaterial. The following assumptions were utilized in the valuation for options granted:

Dividend yield	—%
Risk-free interest rate	3.2%-4.5%
Expected life	3 years

Stock Split

Immediately prior to the consummation of the initial public offering of the Company’s common stock, the number of authorized shares will be increased to             . Also, note that all common share and per share amounts in the consolidated financial statements and notes to the consolidated financial statements have been restated to reflect a              stock split effective immediately prior to the consummation of the initial public offering of the Company’s common stock.

3. Property and Equipment

Property and equipment at December 31, 2005 and 2004, consisted of the following:

	2004		2005
Computer equipment	$	115,933	$	354,915

Notes to Consolidated Financial Statements—(Continued)

Internal Use Software

The Company has adopted the provisions of AICPA Statement of Position (SOP) 98-1, Accounting for the Costs of Software Developed or Obtained for Internal Use. Accordingly, certain costs incurred in the planning and evaluation stage of internal use computer software are expensed as incurred. Costs incurred during the application development stage are capitalized and included in property and equiptment. Capitalized internal use software costs are amortized over the expected economic life of three to five years using the straight-line method. The total amortization expense for the years ended December 31, 2005 and 2004, was $110,053 and $32,798, respectively. At December 31, 2005 and 2004, unamortized internal use software costs were $671,917 and $196,838, respectively.

4. Notes Payable, Bank

During 2005, the Company entered into a $10,000,000 line of credit with a bank that matures June 2006. Outstanding borrowings are limited to 80% of eligible accounts receivable, as defined in the agreement. Outstanding borrowings under the line of credit were $2,923,511 at December 31, 2005. Interest is payable monthly at the prime rate (7.25% at December 31, 2005). The note is collateralized by substantially all of the Company’s assets. The Company is required to comply with certain nonfinancial covenants.

5. Distribution Payable

On December 31, 2005, the Company converted from a cash basis tax payer to an accrual basis tax payer. As a result, each owner of the Company owes taxes on the net income generated as a result of the conversion. The Company has decided to distribute funds to reimburse each owner for their portion of the tax liability created from the conversion to an accrual basis tax payer. The total amount to be distributed to the owners as of December 31, 2005, is $2,987,000. The distribution to each owner will occur in the second quarter of 2006.

6. Commitments and Contingencies

Lease Commitments

During 2004 and 2005, the Company entered into various capital leases for furniture and fixtures that may be purchased for a nominal amount upon expiration of the leases at various dates through November 2010. Monthly payments range from $580 to $6,516. The cost and accumulated depreciation of the capital leases included in furniture and fixtures at December 31, 2005, was $491,779 and $47,818, respectively. Amortization of the related assets is included in depreciation and amortization in the accompanying statements of operations.

In December 2003 (as amended in June 2005), the Company entered into an operating lease agreement for a new facility. The lease agreement expires December 31, 2015, and requires escalating base monthly rental payments ranging from $16,436 to $80,136, plus an additional monthly rental payment for real estate taxes and common area maintenance fees related to the building.

The Company assumed various operating leases for office space and equipment in connection with the acquisition of Ocular Group, LLC (see Note 8). The lease agreements expire at various dates through November 2006, and require escalating base monthly rental payments ranging from $4,706 to $6,249, plus an additional monthly rental payment for common area maintenance fees.

Total rent expense for the years ended December 31, 2005, 2004, and 2003 was $360,627, $307,305, and $100,813, respectively.

IWG allowed the Company to gain access to a new business market and build relationships with very large strategic customers. Subsequently, in October 2003, IWG commenced operations by acquiring certain customer relationships from Express Productions, Inc. in exchange for the issuance of 4,900,000 Class A units of IWG (a 49% interest). IWG also assumed approximately $124,000 of customer deposit obligations in exchange for a note receivable from the shareholders of Express Productions, Inc. As a result of this transaction, the ownership in IWG was reduced to 51%. In March 2005, the Company purchased the remaining 49% interest in IWG in exchange for 150,000 options to purchase Class A common nonvoting units in IW at an exercise price of $.50 per unit (estimated fair value of $.37 per unit) and the forgiveness of advances to minority holders of approximately $313,000. As a result of this acquisition, IW recorded a customer list valued at $241,485 and goodwill of $118,454. The results of operations of IWG have been included in the consolidated financials statements for 2005, 2004, and 2003, with a corresponding minority interest expense for the periods prior to March 2005.

9. Earnings (Loss) Per Share

Basic earnings per common share is calculated by dividing net income available to common shareholders by weighted average number of common shares outstanding. Diluted earnings per share is calculated by dividing net income by the weighted average shares outstanding plus share equivalents that would arise from the exercise of share options and the conversion of preferred shares. Conversion of certain preferred shares were excluded from the calculation in 2005, 2004, and 2003 as they were anti-dilutive.

The computation of basic and diluted earnings (loss) per common share for the years ended December 31, 2005, 2004, and 2003, is as follows:

	Years Ended December 31,

In January 2004, the Company adopted the 2004 Unit Option Plan (the Plan) covering 4,323,500 shares of Class A common stock. Under the Plan, the Company may issue options, at the discretion of the Board, to purchase Class A nonvoting member units. The Plan is administered by the Board of Managers who determines

11. Redeemable Preferred Shares and Members’ Equity

Class A Common Stock

The Company has authorized 31,926,375 common shares, of which 31,926,375 and 29,521,375 shares were issued and outstanding at December 31, 2005 and 2004, respectively. In February 2004, the Company repurchased 2,400,000 Class A voting shares for $634,000.

Preferred Shares

The Company has authorized 937,500 Class B preferred shares, all of which were issued and outstanding at December 31, 2005 and 2004. As of December 31, 2005 and 2004, the Company had a receivable of $188,469 for proceeds to be received for the issuance of Class B shares. Class B preferred shares are entitled to receive a distribution preference over Class A shares at a rate of $.064 per Class B preferred in the first year and increasing $.08 per year to a maximum of $.096 per year, as defined in the agreement, which are payable quarterly in advance beginning on the date of issuance. Class B preferred shares are also entitled to a liquidation preference over the Class A common shares at a rate of $1.60 per Class B preferred share. Class B preferred shares are convertible at the option of each Class B preferred share in such a number of Class A voting common shares as is

F-14

InnerWorkings, LLC and Subsidiary

Notes to Consolidated Financial Statements—(Continued)

determined by dividing $.80 by the Class B conversion price, as defined in the agreement. The Class B conversion price shall initially be $.80, and then adjusted, as defined in the agreement. The Class B preferred shares shall also be automatically converted upon the consent of the majority of the outstanding Class B preferred shareholders or upon the filing of a registration on Form S-1 under the Securities Act of 1933, as defined in the agreement.

Class C Preferred Shares

The Company had authorized 2,580,000 Class C preferred shares, of which 2,580,000 were issued and outstanding at December 31, 2004. The Class C preferred shares were entitled to receive preferential cumulative distributions payable in arrears on a quarterly basis at an annual rate of $.08 per unit, beginning subsequent to June 2003. No Class A or Class B holders would have been paid until all Class C distributions were satisfied. The Class C preferred shares also received a liquidation preference of $1.00 per Class C preferred share before any Class B or Class A members may have received any liquidation payments. Class C preferred shares were convertible automatically into shares of Class A voting common shares upon the consent of the majority of the outstanding Class C preferred shareholders or upon the filing of a registration on Form S-1 under the Securities Act of 1933, as defined in the agreement. The number of Class C preferred shares converted would have been in such a number of Class A voting common shares as was determined by dividing $1.00 by the Class C preferred conversion price in effect at the time of conversion. The Class C preferred conversion price was $1.00 initially, and then adjusted, as defined in the agreement. The Class C preferred share members of the Company had a put option effective March 31, 2008, that required the Company to purchase any such shares of Class C preferred shares held by the holder. The purchase price per Class C preferred share was equal to $1.00 per unit, plus interest computed at 15% per annum, noncompounded, less the amount of all distributions paid to the Class C preferred shareholders. The Company also had a call option on its Class C preferred shares any time after March 31, 2004, that required the holders of the Class C preferred shares to sell any or all shares held. The purchase price was equal to $1.00 per unit, plus interest computed at 15% per annum, noncompounded, less the amount of all distributions paid to the Class C preferred shareholders. In February 2005, the Company received $2,000,000 and 1,000,000 Class C units from a member in exchange for 450,000 Class A voting units and 960,000 Class D preferred units. In addition, in June 2005, the Class C shareholders elected to convert the remaining 1,580,000 Class C units into 1,580,000 Class A voting units.

Class D Preferred Shares

The Company has authorized 1,600,000 Class D preferred shares, of which 1,600,000 and 640,000 shares were issued and outstanding at December 31, 2005 and December 31, 2004, respectively. The Class D preferred shares are entitled to preferential cumulative distributions payable in arrears on a monthly basis at an annual rate of $.375 per unit, beginning subsequent to August 2004. No Class A, Class B, or Class C holders shall be paid until all Class D holders’ distributions are satisfied. In addition, the Class D preferred shares are entitled to receive preferential distributions at an annual rate of $.09375 per unit payable in a lump sum upon the preference satisfaction date, as defined in the agreement. The Company was required under the original terms to pay the preference satisfaction amount, defined as the sum of the Class D preferred purchase price per share plus all accrued and unpaid dividends, in August 2008 (the preference satisfaction date), which could be extended to August 2009. If the preference satisfaction amount is distributed, each D Preferred Unit shall entitle its holder to all of the rights of an A Common Unit, and the preferential rights of each D Preferred Unit shall automatically terminate. In addition, if the preference satisfaction amount is distributed, the Class D holders shall receive 100,000 A Common units. As the Class D preferred shares were mandatorily redeemable at a fixed date, these shares were classified as a liability on the consolidated balance sheet at December 31, 2004, pursuant to SFAS No. 150, Accounting for Certain Financial Instruments With Characteristics of Both Liabilities and Equity, and

F-15

Notes to Consolidated Financial Statements—(Continued)

the related dividends were reflected as interest expense. In February 2005, the terms of the Class D preferred share were amended to remove the required payment date; the holders now have the right to demand redemption of the Class D preferred shares, no earlier than August 15, 2008, and no later than August 15, 2009 (the Final Preference Satisfaction Date). In the event the holders do not demand repayment, the Company shall immediately issue 200,000 Class A voting shares to the holders of the Class D preferred shares as additional consideration. The Class D preferred shares also receive a liquidation preference of $3.125 per share before any Class C, Class B, or Class A members receive any liquidation payments.

For the years ended December 31, 2005 and 2004, the Company did not make any contributions to the plan.

16. New Accounting Pronouncement

On December 16, 2004, the FASB published SFAS No. 123 (revised 2004), Share-Based Payment. This statement eliminates the alternative to use the intrinsic value method of accounting that was permitted in SFAS No. 123 as originally issued and will require recognition of compensation expense related to all equity awards granted after the required effective date and to awards modified, repurchased, or canceled after that date based on the grant date fair values of the awards. This statement is effective as of the first annual reporting period that commences after June 15, 2005. The Company has not yet determined the impact of adopting this statement on its consolidated financial position, results of operations, or cash flows.

17. Related-Party Transactions

In November 2003, the Company entered into a consulting agreement with Zion Consulting, Inc., a business consulting firm.

18. Subsequent Events

Sale of Series E Preferred Shares

In January 2006, the Company issued 10,167,730 shares of Series E units in exchange for $50,000,000 in cash. The Company retained $10,000,000 for working capital and general corporate purposes, while the remaining $40,000,000 redeemed shares held by certain existing shareholders. The Class E preferred shares accrue preferential cumulative dividends at an annual rate of 4%. Class E preferred shares are also entitled to a liquidation preference over the other junior preferred and common stock shareholders an amount equal to 50% of the original purchase price per share plus any accrued but unpaid dividends. In addition, the Series E units shall be automatically converted into common stock with the consent of the Series E shareholders upon a firmly underwritten public offering of common shares at a public offering price no less than 1.75 times the original purchase price within 18 months of the closing and 2.00 times after 18 months and a total offering no less than $25,000,000.

Notes to Condensed Consolidated Financial Statements

March 31, 2006 and 2005

1. Summary of Significant Accounting Policies

Basis of Presentation

The unaudited consolidated financial statements of InnerWorkings, Inc. (the Company, formerly known as InnerWorkings, LLC) included herein have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission and accounting principles generally accepted in the United States for interim financial information. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, all adjustments considered necessary for a fair presentation of the accompanying unaudited financial statements have been included, and all adjustments are of a normal and recurring nature. These interim consolidated financial statements should be read in conjunction with the financial statements and the notes thereto included in the Company’s most recent audited financial statements.

Goodwill and Other Intangibles

Goodwill represents the excess of purchase price and related costs over the value assigned to the net tangible and identifiable intangible assets of businesses acquired. In accordance with Statement of Financial Accounting Standards (SFAS) No. 142, Goodwill and Other Intangible Assets, goodwill is not amortized, but instead is tested for impairment annually, or more frequently if circumstances indicate a possible impairment may exist. The Company evaluates the recoverability of goodwill using a two-step impairment test. For goodwill impairment review purposes, the Company has one reporting unit. In the first step the fair value for the Company is compared to its book value including goodwill. In the case that the fair value is less than the book value, a second step is performed which compares the implied fair value of goodwill to the book value of the goodwill. The fair value for the goodwill is determined based on the difference between the fair values and the net fair values of the identifiable assets and liabilities. If the implied fair value of the goodwill is less than the book value, the difference is recognized as an impairment.

SFAS No. 142 also requires that intangible assets with finite lives be amortized over their respective estimated useful lives, and reviewed for impairment in accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets. The Company’s intangible assets consist of customer lists and noncompete agreements, which are being amortized on the straight-line basis over their estimated useful lives of ten years and five years, respectively.

Following is a summary of the intangible assets:

	December 31, 2005			March 31, 2006			Weighted- Average Life
Customer lists	$	925,485		$	925,485		9.7 years
Noncompete agreement		242,000			242,000		5 years
		1,167,485			1,167,485
Less accumulated amortization		(236,711	)		(275,698	)
Intangible assets, net	$	930,774		$	891,787

Amortization expense related to these intangible assets was $38,987 and $138,360 for the three months ended March 31, 2006 and the year ended December 31, 2005, respectively.

F-22

InnerWorkings, Inc. and Subsidiary

Notes to Condensed Consolidated Financial Statements—(Continued)

The estimated amortization expense for the next five years is as follows:

2006 (remaining 9 months)	$	116,962
2007		137,199
2008		137,199
2009		100,899
2010		88,799
Thereafter		310,729
	$	891,787

Income Taxes

On January 3, 2006, the Company converted from an LLC to a “C” corporation. In connection with this conversion, the Company accounts for income taxes in accordance with SFAS No. 109, Accounting for Income Taxes (SFAS No. 109), under which deferred assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between financial statement carrying values of assets and liabilities and their respective tax bases. As a result of the $40 million share redemption (see note 3), the tax basis of the Company increased resulting in the recognition of a deferred tax asset of $15,600,000, for which a valuation allowance of $7,800,000 was recorded with a corresponding net increase to additional paid in capital of 47,800,000.

Stock-Based Compensation

During the three month periods ended March 31, 2006 and 2005, the Company granted 30,000 and 226,500 options, respectively, to various employees of the company. Outstanding stock options have an expiration date ten years from the date of grant and begin vesting as early as the date of grant, dependent upon the individual agreements.

Prior to January 1, 2006, the Company accounted for stock-based employee compensation arrangements in accordance with provisions of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued to Employees, and complied with the disclosure requirements of Financial Accounting Standards Board (FASB) No. 148, Accounting for Stock-Based Compensation – Transition and Disclosure – An Amendment of FASB Statement No. 123. Effective January 1, 2006, the Company adopted the fair value recognition provisions of FAS 123 (R), Share-Based Payments, using the prospective transition method and Black-Scholes as the option valuation model. Under the transition method, the Company continues to account for nonvested equity awards outstanding at the date of adopting Statement 123 (R) in the same manner as they had been accounted for prior to adoption. As a result, under APB No. 25, compensation expense is based on the difference, if any, on the grant date between the estimated fair value of the Company’s stock and the exercise price of options to purchase that stock. The compensation expense is then amortized over the vesting period of the stock options.

InnerWorkings, Inc. and Subsidiary

Notes to Condensed Consolidated Financial Statements—(Continued)

To value option grants in accordance with SFAS No. 123, the Company used the minimum value method. Net income on a pro forma basis for the three month period ended March 31, 2005, as if compensation expense for employee option-based awards were determined using the minimum value method, is as follows:

	Three Months Ended March 31, 2005
Net income, as reported	$	574,649
Pro forma adjustment:
Stock-based compensation, included in net income		87,500
Compensation expense		(110,603	)
Pro forma net income	$	551,546
Net income per share, as reported
Basic	$	0.01
Diluted	$	0.01
Pro forma net income per share:
Basic	$	0.01
Diluted	$	0.01

To value option grants in accordance with SFAS No. 123, the Company used the minimum value method. The minimum values of the options issued were immaterial. The following assumptions were utilized in the valuation for options granted:

Dividend yield	—%
Risk-free interest rate	3.2%-4.5%
Expected life	3 years

Stock Split

Immediately prior to the consummation of the initial public offering of the Company’s common stock, the number of authorized shares will be increased to                 . Also, note that all common share and per share amounts in the condensed consolidated financial statements and notes to the condensed consolidated financial statements have been restated to reflect a                  stock split effective immediately prior to the consummation of the initial public offering of the Company’s common stock.

2. Earnings Per Share

Basic earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding. Diluted earnings per share is calculated by dividing net income by the weighted average shares outstanding plus share equivalents that would arise from the exercise of share options and the conversion of preferred shares. Conversion of certain preferred shares were excluded from the calculation in 2005 and 2006 as they were anti-dilutive. The computations of basic and diluted earnings per common share for the three months ended March 31, 2006 and 2005 are as follows:

	Three Months Ended March 31,

3. Series E Preferred Shares

In January 2006, the Company issued 10,167,730 shares of Series E units in exchange for $50,000,000 in cash. The Company retained $10,000,000 for working capital and general corporate purposes, while the remaining $40,000,000 redeemed shares held by certain existing shareholders. The Class E preferred shares accrue preferential cumulative dividends at an annual rate of 4%. Class E preferred shares are also entitled to a liquidation preference over the other junior preferred and common stock shareholders an amount equal to 50% of the original purchase price per share plus any accrued but unpaid dividends. In addition, the Series E units shall be automatically converted into common stock with the consent of the Series E shareholders upon a firmly underwritten public offering of common shares at a price no less than 1.75 times the original purchase price within 18 months of the closing and 2.00 times after 18 months and total offering no less than $25,000,000.

As a result of the issuance of Series E units, the Company amended the Series B and Series D dividend rights. The dividend rights were amended to pay a cash dividend at the rate of 4% of the original issue price. In addition, the dividends shall be cumulative and accrue from and after the date of issuance. The dividends will

only become payable upon the occurrence of certain events, including a liquidation event, conversion or redemption of the shares or if the Board declares them to be paid.

4. Conversion to InnerWorkings, Inc.

On January 3, 2006, the Company completed its conversion to a corporate structure whereby InnerWorkings, LLC converted to InnerWorkings, Inc. As a result, each voting A common unit of the LLC converted to a fully paid share of Class A Common Stock, with a par value $0.0001 per share. The non-voting A common units converted to a fully paid share of Class B Common Stock, with a par value of $0.0001 per share. In addition, each B and D preferred unit of the LLC converted to fully paid shares of Series B and Series D Preferred Stock, respectively, both with a par value of $0.0001.

5. Related Parties

In November 2003, the Company entered into a consulting agreement with Zion Consulting, Inc., a business consulting firm. Under the terms of the consulting agreement, the Company paid $40,600 and $22,500 to Zion Consulting for services rendered during the three months ended March 31, 2006 and 2005, respectively. The sole shareholder and president of Zion Consulting is the spouse of one of the Company’s stockholders.

In February 2005, the Company acquired a 10.2% ownership interest in Echo Global Logistics, LLC (Echo), an enterprise transportation start-up management firm with no net assets, liabilities or historical operating results for $125,000. The remaining investors in Echo include certain shareholders and directors of IW, as well as key members of the Company’s management team. The Company provides general management services to Echo, including financial management, legal, accounting, tax, treasury services, employee benefit plan and marketing services, which are billed based on the percentage of time the Company’s employees spend on these services. The total amount billed for general management services during the three months ended March 31, 2006 was $19,296. In addition, Echo provided transportation services to the Company during 2006. As consideration for these services, Echo billed the Company $132,930 for the three months ended March 31, 2006. The Company also sub-leases a portion of our office space to Echo. Effective January 1, 2006, the Company entered into a sub-lease agreement with Echo pursuant to which Echo leases approximately 20% of our office space for approximately $7,500 per month.

The Company sub-leases a portion of our office space to Incorp, LLC. Effective January 1, 2006, the Company entered into a sub-lease agreement with Incorp pursuant to which Incorp leases approximately 20% of our office space for approximately $7,500 per month.

Item 14. Indemnification of Directors and Officers

Delaware General Corporation Law

We are incorporated under the laws of the State of Delaware. Our second amended and restated certificate of incorporation (filed as Exhibit 3.2 to this registration statement) and amended and restated by-laws (filed as Exhibit 3.4 to this registration statement), each of which will be become effective immediately prior to the closing of this offering, provide for the indemnification of our directors, officers, employees and agents to the fullest extent permitted under the Delaware General Corporation Law. Section 145 of the General Corporation Law of the State of Delaware provides that a corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the person’s conduct was unlawful.

In addition, we have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’

II-1

fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that a Delaware Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director:

· for any breach of the director’s duty of loyalty to InnerWorkings or its stockholders;

· for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

· for payment of dividends or stock purchases or redemptions by the corporation in violation of Section 174 of the Delaware General Corporation Law; or

· for any transaction from which the director derived an improper personal benefit.

Our second amended and restated certificate of incorporation which will become effective immediately prior to the closing of this offering includes such a provision. As a result of this provision, InnerWorkings and its stockholders may be unable to obtain monetary damages from a director for certain breaches of his or her fiduciary duty to InnerWorkings. This provision does not, however, eliminate a director’s fiduciary responsibilities and, in appropriate circumstances, equitable remedies such as injunctive or other forms of non-monetary relief will remain available under Delaware law. The provision also does not affect a director’s responsibilities under any other laws, such as the federal securities laws.

Indemnification Agreements

We intend to enter into indemnification agreements, a form of which is attached as Exhibit 10.8, with each of our directors and officers and certain key employees that may be broader than the specific indemnification provisions contained in the Delaware General Corporation Law, as amended from time to time. These indemnification agreements may require us, among other things, to indemnify our directors and officers and certain key employees against liabilities that may arise by reason of their status or service. These indemnification agreements may also require us to advance all expenses incurred by the directors or officers or certain key employees in investigating or defending any such action, suit or proceeding. However, an individual will not receive indemnification for judgments, settlements or expenses if he or she is found liable to the company (except to the extent the court determines he or she is fairly and reasonably entitled to indemnity for expenses) for settlements not approved by the company or for settlements and expenses if the settlement is not approved by the court.

Underwriting Agreement

The Underwriting Agreement (filed as Exhibit 1.1 to this registration statement) provides that the underwriters are obligated, under certain circumstances, to provide indemnification for InnerWorkings and its officers, directors and employees for certain liabilities, including liabilities arising under the Securities Act of 1933, as amended, or otherwise.

Directors’ and Officers’ Liability Insurance

InnerWorkings maintains directors’ and officers’ liability insurance policies, which insure against liabilities that directors or officers may incur in such capacities. These insurance policies, together with the indemnification

II-2

agreements, may be sufficiently broad to permit indemnification of our directors and officers for liabilities, including reimbursement of expenses incurred, arising under the Securities Act of 1933, as amended, or otherwise.

THE BOARD OF DIRECTORS AND SHAREHOLDERS OF INNERWORKINGS, LLC AND SUBSIDIARY

We have audited the consolidated financial statements of InnerWorkings, LLC and Subsidiary as of December 31, 2005 and 2004, and for each of the three years in the period ended December 31, 2005, and have issued our report thereon dated March 15, 2006, except for the “Stock Split” section of Note 2 as to which the date is              (included elsewhere in this Registration Statement). Our audits also included the financial statement schedule listed in Item 16(b) of Form S-1 of this Registration Statement. This schedule is the responsibility of the Company’s management. Our responsibility is to express an opinion based on our audits.

In our opinion, the financial statement schedules referred to above, when considered in relation to the basic financial statements taken as a whole, present fairly in all material respects the information set forth therein.

Item 17. Undertakings

The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

II-5

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 Securities Act and will be governed by the final adjudication of such issue.

The undersigned registrant hereby undertakes that:

(1) To provide to the underwriters at the closing specified in the underwriting agreement, certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

(2) 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 of 1933 shall be deemed to be part of this registration statement as of the time it was declared effective.

(3) 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.
