PART I

THE COMPANY



|ITEM 1. | BUSINESS
|------- | --------

The following description of our
business should be read in conjunction with the information included elsewhere in this Form 10-K for the year ended December 31, 2008. This description contains forward-looking statements that involve risks and uncertainties. Our actual results
could differ significantly from the results discussed in the forward-looking statements due to the factors set forth in Risk Factors and elsewhere in this Form 10-K. References in this Form 10-K to we, our,
us, or the Company, refer to Catalyst Health Solutions, Inc.

Overview

Catalyst Health Solutions, Inc. (formerly HealthExtras, Inc.) is a full-service pharmacy benefit management (PBM) company. The change of our
corporate name was completed on October 1, 2008 and served to better align our corporate brand with that of our most visible operation, Catalyst Rx. Our name change capitalizes on Catalyst Rxs brand equity and creates consistency for our
shareholders and clients. Our clients include self-insured employers, including state and local governments; managed care organizations (MCOs); unions; third-party administrators (TPAs); hospices; and individuals who contract
with us to administer the prescription drug component of their overall health benefit programs.

We provide our clients access to a
contracted, non-exclusive national network of approximately 61,000 pharmacies. We provide our clients members with timely and accurate benefit adjudication, while controlling pharmacy spending trends through customized plan designs, clinical
programs, physician orientation programs and member education. We utilize an electronic point-of-sale system for eligibility verification and plan design information and offer access to rebate arrangements for certain branded pharmaceuticals. When a
member of one of our clients presents a prescription or health plan identification card to a retail pharmacist in our network, the system provides the pharmacist with access to online information regarding eligibility, patient history, health plan
formulary listings and contractual reimbursement rates. The member generally pays a co-payment to the retail pharmacy and the pharmacist fills the prescription. We electronically aggregate pharmacy benefit claims, which include prescription costs
plus our claims processing fees, for consolidated billing and payment. We receive payments from clients, make payments of amounts owed to the retail pharmacies pursuant to our negotiated rates and retain the difference (except where we have entered
into pass-through pricing arrangements with clients) including applicable claims processing fees. Total claims processed increased to 52.0 million in 2008 from 41.5 million in 2007. Our revenue increased by approximately 37% to $2.5
billion in 2008 from $1.9 billion in 2007.

Pharmacy benefit claim payments from our clients are recorded as revenue, and prescription
costs to be paid to pharmacies are recorded as direct expenses. Under our network contracts, we generally have an independent obligation to pay pharmacies for the drugs dispensed and, accordingly, have assumed that risk independent of our clients.
When we administer pharmacy reimbursement contracts and do not assume a credit risk, we record only our administrative or processing fees as revenue. Rebates earned under arrangements with manufacturers are recorded as a reduction of direct
expenses. The portion of manufacturer rebates due to clients is recorded as a reduction of revenue.

We were incorporated in Delaware in 1999. Our principal executive offices are located at 800 King Farm Boulevard, 4thFloor, Rockville, Maryland 20850. Our telephone number is 301-548-2900.

Our Internet Web site is
www.CatalystHealthSolutions.com. We make available free of charge on or through the Web site our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any amendments to those reports filed or furnished
pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. This reference to our Web site is for the convenience of
shareholders as required by the SEC and shall not be deemed to incorporate any information on the Web site into this Form 10-K or our other filings with the SEC.

Our Web site is also a key source of important information about us. We routinely post to the Investor Information section of our Web site important information about our business, our operating results and our

financial condition and prospects, including, for example, information about important acquisitions and dispositions, our earnings releases and certain
supplemental financial information related or complementary thereto. We also have a Corporate Governance page in the Investor Information section of our Web site that includes, among other things, copies of our Code of Ethics & Conduct and
the charters for each standing committee of our Board of Directors, which currently are: the Audit Committee, the Compensation Committee, and the Ethics, Governance and Nominating Committee. Copies of our Bylaws and these charters and policies are
also available in print to shareholders upon request.

The Industry

The PBM industry has developed and grown in response to the increased utilization of pharmaceuticals, increased unit costs and broader application of prescription drugs to various conditions. These factors have
combined to create a significant and recurring escalation in the cost of drug coverage offered by self-insured employers, including state and local governments, MCOs, unions, TPAs and hospices. In order to understand, manage and mitigate these
trends, many of these payor organizations have contracted for the specialized services offered by PBMs. According to the journal Health Affairs, overall pharmacy expenditures in the United States are expected to be approximately $266.0
billion in 2009, a 7.7% increase over 2008. While pharmacy expenditure increases have moderated since a peak period from the late 1990s through 2005, average annual increases of 8.2% are expected through 2017. Price growth is expected to
contribute to more than half of the total of those expected spending increases, with the remainder resulting primarily from volume and utilization.

Factors contributing to the increase in pharmacy spending include:



| |  |  | Greater reliance on drug therapy by the physician community;
| | - |  | ------------------------------------------------------------



| |  |  | Increased preventative prescribing including the management of high cholesterol levels and digestive disorders;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | Efforts by drug manufacturers to increase market share and extend single-source brand use;
| | - |  | ------------------------------------------------------------------------------------------



| |  |  | The introduction of improvements over existing therapies, which normally carry higher unit prices than existing formulations;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------



| |  |  | Increased patient demand and education as a result of direct-to-consumer advertising and other pharmaceutical marketing or promotional efforts;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | An aging workforce;
| | - |  | -------------------



| |  |  | Increased obesity among all age groups;
| | - |  | ---------------------------------------



| |  |  | Improved techniques and technology to detect and diagnose diseases; and
| | - |  | -----------------------------------------------------------------------



| |  |  | Increased utilization and rising costs of specialty drugs, which are high-cost drugs used to treat complex, serious and/or life-threatening conditions such as
cancer and HIV/AIDS.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

PBMs are responsible for implementing and administering benefit plans that are care-effective and
also seek to lower overall prescription spending by encouraging greater generic utilization, increasing the proportion of brand drugs dispensed from the preferred category and encouraging, where appropriate, non-prescription therapy and treatment
alternatives. These objectives are accomplished through a combination of clinical, administrative, educational and technology initiatives directed towards pharmacies, physicians and members.

Over the past several years, plan designs have increasingly focused on the use of three-tier or four-tier co-payment structures. Co-payments represent
that portion of the cost of a prescription paid for by the member at the time the drug is dispensed. The purpose of these tiered designs and the use of drug-specific formulary lists is to create financial incentives for members to utilize generic
drugs where available and to select the most cost-effective brand drugs indicated for a specific diagnosis or condition. In general, these plans incorporate the lowest member co-payments for generic drugs, with increases in co-payments for preferred
brand drugs and co-payments reaching their highest level for non-preferred brands. Typically, under a three-tier payment structure, these categories might require member co-payments of $10, $25 and $40 respectively. The use of these tiered plans has
increased significantly over the past decade and now applies to more than 75% of employer-sponsored members. In recent years, both the levels of member co-payment and the differential between tiers have continued to increase.

Competition

We believe the primary competitive factors in our business are price, quality of service and scope of available services. Market share for PBM services in the United States is highly concentrated, with a few firms controlling more than 70%
of prescription volume. These larger national and regional PBMs, such as Medco Health Solutions, Inc., Express Scripts, Inc. and CVS Caremark, Inc., have significantly greater financial, marketing and technological resources at their disposal to
expand client base and grow their business. Large health insurers and certain MCOs, drug retailers and physician practice management companies also have their own PBM capabilities.

Scale is a particularly important factor in negotiating prices with pharmacies and drug manufacturers. Though we have other advantages to offset our
comparatively smaller scale, we could face more pricing competition in the future.

Some of our services, such as disease management
services, informed decision counseling services and medical information management services, also compete with those being offered by pharmaceutical manufacturers, specialized disease management companies and information service providers.

We have demonstrated our ability to serve a broad range of clients from large managed care organizations, employer groups and state
governments to unions with fewer than a thousand members. We believe the following are our principal strengths and are critical to our ongoing competitiveness:

Flexible and Customized Services  We believe it is important to provide our clients with customized solutions and recommendations made with their best interests in mind. Accordingly, the formulary and
plan designs we suggest to clients are highly flexible and not influenced by manufacturer relationships.

Local Market Presence Our local market presence in California, Florida, Georgia, Hawaii, Iowa, Louisiana, Maryland, Michigan, Mississippi, Nevada, New Mexico, Ohio, Oklahoma, Pennsylvania, Puerto Rico, Texas and the Carolinas allows us to offer attractive
benefit pricing based on local pharmacy network rates and formulary design. Through these local offices we provide strategic account management and clinical services, including targeted physician education programs.

Information-Based Cost Containment Methods Through the use of our customized information technology systems we provide our clients and
members with access to information on a rapid basis, which allows us to work with our clients and members more collaboratively to manage the costs of their prescription drugs. For example, our Web-based systems allow our clients to choose which
metrics are most important to them for the purposes of evaluating their pharmacy benefit management program. We then provide customized reporting solutions for these key performance indicators. In addition, members can access our Web-based programs
to evaluate their costs for selected drugs and pharmacies, comparable drug and pharmacy alternatives including low cost retail programs, and the savings opportunities represented by each. We believe these services allow us to further differentiate
ourselves from our competitors.

Our Business Strategy

We seek to continue to increase our client base, revenue and profits. We intend to accomplish this by capitalizing on our competitive strengths and helping to address the challenges confronting payors.

Increasing our PBM Client Base by Targeting Certain Market Segments.

We have identified certain segments of the market that provide us with the greatest opportunity for growth. We intend to focus our sales and marketing efforts to target these segments in order to gain new clients and
increase our membership base and revenues. Our analysis of our market opportunity by segment is as follows:



| |  |  | Large Employer Groups (Self-Insured):Employers in this segment are large enough to need a full-service PBM solution to manage their increasing prescription
benefits costs. By utilizing our information-based cost containment strategies, we offer these clients favorable results compared to larger PBMs, and a greater level of client and customer service.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | State and Local Governments:State and local governments are also employers who provide health benefits to their employees and retirees. Some state
governments have a workforce and retiree population of comparable size to that of a Fortune 1000 employer. These clients seek the same customer service,
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | attention to detail and bottom line results as private sector employers. Because the vast majority of members in this market segment are geographically
concentrated, we can analyze the prescribing and utilization trends associated with a state and local government entity and take measures designed to educate prescribing physicians and improve formulary compliance in a particular region. These
physician interactions draw on peer-reviewed clinical studies, generic drug utilization patterns and the insights offered by the physicians themselves with the goal to deliver better care at lower costs.
| | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | MCOs:There are hundreds of MCOs that each provide coverage to fewer than 200,000 lives. We believe that MCOs of this size are increasingly dissatisfied with
the level of service and results they receive from larger PBMs, as those companies devote most of their attention to MCOs that have more than one million members. We have demonstrated that we can provide these MCOs with a complete, full-service PBM
that includes all of the features that larger PBMs offer, with superior customer service, market-specific retail networks and customized benefit plans.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Unions:Union members make up over 10% of the workforce and work in all types of jobs and industries, according to the AFL-CIO. They include teachers, coal
miners, construction workers, nurses, firefighters, musicians, engineers, electricians and more. Through collective bargaining, unions are able to negotiate for healthcare benefits that deliver a high quality of care with minimal member cost
share. Unions are challenged with maintaining the same benefit standards while budgets and the union workforce face decreases due to the economy. We provide solutions that are aligned with the unions missions and values by delivering proven
programs that reduce drug trend without shifting costs to beneficiaries.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Third-Party Administrators (TPAs):There are hundreds of TPAs in the U.S. that focus primarily on administering the health benefits of their clients. TPAs
provide services to millions of employees, dependents and retirees. As the TPA market continues to consolidate; and TPA clients increasingly seek out complete health benefits solutions from their TPAs, we believe an increasing number of TPAs
will be seeking a PBM to administer the prescription benefits of their clients.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Hospices:The number of patients served through the hospice industry has grown dramatically for the past 10 years. According to the National Hospice and
Palliative Care Organization, an estimated 1.3 million patients received services from hospice in 2006. We believe there are opportunities in this growth industry to help reduce the costs of care through improved operational
efficiencies and economies of scale with Catalyst Rx.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Leveraging Local Market Dynamics to Build Customized Networks and Manage Drug
Spending.

Although clients contract with us to provide PBM services nationwide, capitalizing on local and regional market dynamics is
an effective way to manage drug spending and differentiate our PBM services from those offered by our competitors.



| |  |  | Customized Pharmacy Networks:To obtain greater pharmacy discounts for our clients, we work with clients to identify pharmacies that will agree to deeper
prescription discounts in a specific locality, based on the concentration of client members in that area and the resulting store traffic those members represent to a drug, grocery, or retail drug stores non-pharmacy business. We have
established customized pharmacy networks in the Carolinas, Florida, Georgia, Iowa, Louisiana, Mississippi, Nevada, New Mexico, Ohio, Oklahoma, Pennsylvania, Puerto Rico and Texas and we are also expanding our networks in other parts of the country
to support our growing client base.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Data Analysis and Reporting to Improve Cost Management and Quality of Care:We perform client-specific data analysis to monitor trends and develop insights
and recommendations that result in improved care while reducing costs. Many PBMs offer a variety of data analysis techniques from both a clinical and financial perspective. We differentiate ourselves by using the information we derive from our
systems to obtain regionally favorable prescription pricing, to actively influence the drivers of prescription drug utilization and to monitor clinical formulary and disease management trends.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Extensive Use of Internet Tools to Enhance Account Management Effectiveness:We provide our clients Web-enabled decision support tools for prescription
benefit plan management, clinical evaluations, disease management and compliance monitoring. These data analysis and reporting capabilities allow clients to assess top-level trend information for total population management and to analyze detail for
a particular drug, physician, member, or pharmacy. This functionality enables our clients to measure successes relative to formulary and disease management initiatives and assists in the identification of specific patient populations that may
benefit from specialty or other pharmacy programs.

Offering Our Clients a Variety of Specialized Services Focused On Improving Health Outcomes.

Comprehensive Spectrum of Clinical and Other Services Our clinical service teams work closely with clients to design and administer pharmacy
benefit plans that use formularies, plan design, and other techniques to promote clinically appropriate and cost-effective drug usage. Our programs focus on helping payors control the high costs associated with prescription medications while
providing their members with an exceptional level of personalized care that can lead to increased compliance to vital drug regimens, and improved member satisfaction. We are often able to influence physician prescribing patterns by comparing their
individual prescribing trends to that of other physician peer groups, and encouraging change where practices differ from peer group norms and medical best practices. Because we operate with significant geographic focus, the consultations between our
clinical pharmacists and local physicians tend to have higher levels of effectiveness compared with less concentrated initiatives. Similarly, our programs with retail pharmacies support therapeutic interchange programs that encourage the evaluation
of cost-effective drug alternatives where appropriate. We also offer consulting services to assist clients in designing their benefit plan offering and in developing education and communication programs to support care and cost-effective
prescription drug behavior. A more detailed description of selected clinical and other services we perform include:



| |  |  | Benefit Plan Design and Consultation:Our pharmacy professionals work in conjunction with our clients to design benefit plans that meet the specific needs of
our clients and their members. We seek to help maximize the quality of care members receive while controlling the cost of providing prescription pharmaceutical coverage by, among other efforts, creating financial incentives and reimbursement
limitations on the drugs covered by our plan, offering generic utilization incentives and establishing reimbursement parameters on the amount of a drug that can be obtained in a specific period.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Formulary Administration:We seek to maximize the clinical appropriateness of all drugs covered by our plans. To do so, we actively seek to promote the use
of drugs that our clients identify as the preferred prescription alternative for certain clinical conditions, thereby reducing unnecessary overuse of new drugs or reformulations of old drugs in inappropriate circumstances.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Formulary Compliance and Therapeutic Intervention Programs:We seek to encourage compliance with the formularies established in coordination with our clients
by instituting guidelines that create financial incentives both for our clients members and our pharmacy networks to comply with the formulary. At the same time, we also encourage the appropriate use of prescription drugs through prescriber
and member education programs. Finally, we seek to encourage the use of generic formulations of branded pharmaceuticals, thereby lowering the cost of prescription pharmaceuticals without compromising efficacy.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Advanced Decision Support and Data Analysis Services:We are able to help manage the cost expansion in prescription drug coverage through intensive analysis
and review of utilization data of our clients members. By recognizing inappropriate use or dispensing of specific prescription drugs for certain member groups or at certain network pharmacies, we are able to help manage rapid inflation in
prescription expenses.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Flexible Customized Reporting via Secure Internet Connection:We provide our clients members the ability to compare options available to them for
certain prescription drugs through our comprehensive Web site. For example, on our Web site, members can compare the various options available to them for allergy medication, such as branded prescription pharmaceuticals, a generic alternative, or an
over-the-counter formulation.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Disease Management Services We assist clients in managing the cost and
treatment of specific chronic diseases in order to improve medical outcomes and lower the overall cost of healthcare. These disease management programs monitor the contracted population and intervene when individuals demonstrate symptoms of a
specific disease or high-risk indication.

##### Table of Contents

Our disease management programs are the responsibility of a dedicated team of clinicians and have been
developed around three key approaches:



| |  |  | Data Analysis and Integration:We evaluate and identify medical, laboratory, pharmacy and other relevant data within an identified population.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Case Identification:We identify patients who have a specific disease and evaluate the appropriateness of targeted interventions.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------



| |  |  | Clinical and Program Interventions:We communicate with identified patients and offer enhanced education about their condition and effective management
tools. We also integrate our recommendations into our physician education initiatives, including treatment guidelines, patient profiles and patient management tools. Case management intervention programs are coordinated with other caregivers to
monitor outcomes and improve overall care.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Generic Advantage Plan  The Catalyst Rx Generic Advantage Plan
is designed to inform members how to obtain competitively priced generic medications by comparing pricing through various fulfillment channels. Members are shown plan-based pricing for a variety of fulfillment methods, including generics at retail
pharmacies, mail order and retail generic programs (commonly referred to as $4 generic programs or low-cost retail programs, such as those programs offered at Walmart, Target and other retail pharmacies). The Generic
Advantage Plans pricing comparisons differentiate us from our PBM competitors who sometimes channel volume to mail order or certain retail outlets when more affordable options are available.

Mail Service Pharmacy Whether through a preferred mail service pharmacy provider or through Immediate Pharmaceutical Services, Inc.
(IPS), our newly acquired mail service pharmacy, our mail service pharmacy program delivers quality, service and savings. Mail service is a significant extension of any pharmacy benefit plan as it provides economies of scale, minimizes
prescription dispensing costs and provides the convenience of excellent service and home delivery. Through IPS, our clients are also able to access acquisition-based mail service prices, providing competitive prices on generic drugs in the market.

Specialty Pharmacy Services We offer a convenient specialty pharmacy solution for our clients and members. Our program
offers specialty pharmacy products at discounts over standard retail pharmacy, includes complex therapies and provides dedicated therapeutic management programs for individuals challenged by chronic and costly health conditions.

Hospice Care PBM Services Through our recent acquisition of HospiScript Services, LLC, one of the nations largest providers of
hospice PBM services, we are able to provide specialized services for facilities focusing on end-of-life care. We deliver reduced pharmaceutical and administrative expenses; custom dispensing parameters; access to hospice-trained pharmacist
consultation; online reporting for pharmaceutical expenses and utilization patterns; and powerful educational resources for nurses, pharmacists and hospice administrators.

Pursuing Selective Acquisitions.

Consolidation has been, and may continue to be, an important factor
in all aspects of the pharmaceutical industry, including the PBM business. We will continue to evaluate additional acquisition opportunities to enhance our business strategy.

We strive to timely integrate our strategic acquisitions. Our acquisitions have provided us with a more diverse and complete set of products and services
to sell to a larger customer base and have expanded our geographic presence. The acquisitions have also allowed us to better capture efficiencies in corporate overhead and information technology investments. In each of the acquisitions, we achieved
our objectives by integrating operations, realizing operating efficiencies, improving profitability and growing the revenue base of the acquired businesses. We will continue to look for acquisition opportunities that complement our existing
operations and have characteristics similar to those of the companies previously acquired. These characteristics include geographic membership concentrations, opportunities to improve profitability and a base from which to generate revenue growth.
See Part II, Item 7, Managements Discussion and Analysis of Financial Condition and Results of Operations  Acquisitions for additional information.

Customers.

In 2008, our largest customers, Wellmark Blue Cross Blue Shield of Iowa and the State of
Maryland, accounted for 18% and 12% of our consolidated revenue, respectively. Our ten largest customers, including

Wellmark Blue Cross Blue Shield of Iowa and the State of Maryland, accounted for 64% of our 2008 consolidated revenue. In 2007, Wellmark Blue Cross Blue
Shield of Iowa accounted for 20% of our consolidated revenue and no other customer accounted for over 10% of our 2007 consolidated revenue. Our ten largest customers, including Wellmark Blue Cross Blue Shield of Iowa, accounted for 58% of our 2007
consolidated revenue.

Government Regulation - Overview

Various aspects of our business are governed by federal and state laws and regulations. Because sanctions may be imposed for violations of these laws, compliance is a significant operational requirement. We believe we
are in substantial compliance with all existing legal requirements material to the operation of our business. There are, however, significant uncertainties involving the application of many of these legal requirements to our business. In addition,
there are numerous proposed health care laws and regulations at the federal and state levels, many of which could adversely affect our business, results of operations and financial condition. We are unable to predict what additional federal or state
legislation or regulatory initiatives may be enacted in the future relating to our business or the health care industry in general, or what effect any such legislation or regulations might have on us. We also cannot provide any assurance that
federal or state governments will not impose additional restrictions or adopt interpretations of existing laws or regulations that could have a material adverse effect on our business or financial performance.

Some of the state laws described below may be preempted in whole or in part by the Employee Retirement Income Security Act of 1974, ERISA,
which provides for comprehensive federal regulation of employee benefit plans. However, the scope of ERISA preemption is uncertain and is subject to conflicting court rulings. We also provide services to certain clients, such as governmental
entities, that are not subject to the preemption provisions of ERISA.

Federal Laws and Regulations Affecting Our Business

The following descriptions identify various federal laws and regulations that affect or may affect aspects of our business:

Medicare Prescription Drug, Improvement, and Modernization Act of 2003.

The Medicare voluntary outpatient prescription drug benefit, Part D, was established under the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, or MMA. The MMA also
created guidelines for Medicare HMOs, termed Medicare Advantage Plans, which offer both an outpatient prescription drug benefit and health care coverage.

Medicare beneficiaries who elect Part D coverage pay a monthly premium for the covered outpatient drug benefit. Assistance with premiums and cost sharing are provided to eligible low-income beneficiaries. The
voluntary outpatient prescription drug benefit requires coverage of essentially the same pharmaceuticals that are approved for the Medicaid program, although selection may be restricted through a formulary. The outpatient prescription drug benefit
is offered on an insured basis by prescription drug plans, PDPs, in 34 regions across the United States and by Medicare Advantage Plans, along with health care coverage, in 26 regions across the United States.

We are neither a PDP nor a Medicare Advantage Plan; however, we contract with PDPs and Medicare Advantage Plans, collectively Part D Plans,
to provide various PBM services. In our capacity as a subcontractor with certain Part D Plan clients, we are indirectly subject to certain federal rules, regulations, and sub-regulatory guidance pertaining to the operation of Medicare Part D. If the
federal Centers for Medicare & Medicaid Services, referred to as CMS, determines that we have not performed satisfactorily as a subcontractor, CMS may request our PDP or Medicare Advantage Plan client to revoke our Part D
activities or responsibilities under the subcontract. While we believe that we provide satisfactory levels of service, under our respective subcontracts, we can give no assurances that CMS or a Part D Plan will not terminate our business
relationships insofar as they pertain to Medicare Part D.

Among other things, PDPs and Medicare Advantage Plans are subject to provisions
of the MMA intended to deter fraud, waste and abuse and are strictly monitored by CMS and its contracted Medicare Drug Integrity Contractors, MEDICs, to ensure that Part D program funds are not spent inappropriately. Among
other things, the



7

##### Table of Contents

fraud, waste and abuse provisions of CMSs Medicare Prescription Drug Benefit Manual cites the following examples of potential PBM fraud, waste and
abuse risks in connection with Part D: prescription drug switching, unlawful remuneration, inappropriate formulary decisions, prescription drug splitting or shorting, and failure to offer negotiated prices. CMS has offered additional sub-regulatory
guidance regarding some of these risk areas, particularly with respect to the Part D formulary decision making process which is highly regulated by CMS. We believe that we are in substantial compliance with the applicable laws pertaining to these
risk areas. However, no assurance can be given that we will not be subject to scrutiny or challenge under one or more of the underlying laws by the government enforcers or private litigants.

CMS requires PDPs and Medicare Advantage Plans to report 100% of all price concessions received for PBM services. The applicable CMS guidance suggests
that best practices would require PDPs and Medicare Advantage Plans to contractually require the right to audit their PBMs as well as require 100% transparency as to manufacturer rebates paid for drugs provided under the sponsors plan,
including the portion of such rebates retained by the PBM as part of the price concession for the PBMs services. Additionally, on December 5, 2007, CMS issued a final regulation requiring Part D Plan sponsors to ensure through their
contractual arrangements with first tier, downstream and related entities (which would include PBMs) that CMS has access to such entities books and records pertaining to services performed in connection with Part D. The December 5, 2007
final regulation also suggests that Part D Plan sponsors should contractually require their first tier, downstream and related entities to comply with certain elements of the sponsors compliance program. The applicable provisions of the CMS
final regulation took effect on January 1, 2009. We do not anticipate that such disclosure and auditing requirements, to the extent required by Medicare plan partners, will have a materially adverse effect on our business, results of
operations, financial condition, or cash flows.

On January 6, 2009, CMS issued a final regulation requiring Part D plan sponsors to
calculate beneficiary cost sharing based upon the price ultimately received by the pharmacy or other dispensing provider, rather than upon the price paid by the plan, beginning in 2010. Such calculation could potentially result in lower pharmacy
claims reimbursement by Part D plan sponsors to PBMs. In addition, the rule requires that any profit realized or loss incurred by a PBM through price negotiations with pharmacies or manufacturers be included as administrative costs to the plan
rather than being factored into drug costs for reimbursement purposes. We do not expect that such changes will materially adversely affect our business, results of operations, financial conditions or cash flows.

Federal Anti-Remuneration/Fraud and Abuse Laws.

The
federal healthcare Anti-Kickback Statute prohibits, among other things, an entity from paying or receiving, subject to certain exceptions and safe harbors, any remuneration, directly or indirectly, to induce the referral of individuals covered by
federally funded health care programs, including Medicare, Medicaid and the Civilian Health and Medical Program of the Uniformed Services, CHAMPUS, or the purchase, or the arranging for or recommending of the purchase, of items or
services for which payment may be made in whole or in part under Medicare, Medicaid, CHAMPUS or other federally funded health care programs. Sanctions for violating the Anti-Kickback Statute may include imprisonment, criminal and civil fines, and
exclusion from participation in the federally funded health care programs.

The federal healthcare Anti-Kickback Statute has been
interpreted broadly by courts, the Office of Inspector General, referred to as the OIG, within the U.S. Department of Health & Human Services, the DHHS, and other administrative bodies. Because of the statutes
broad scope and the limited statutory exceptions, federal regulations establish certain safe harbors from liability. For example, safe harbors exist for certain properly disclosed and reported discounts received from vendors, certain investment
interests, certain properly disclosed payments made by vendors to group purchasing organizations, certain personal services arrangements, and certain discount and payment arrangements between PBMs and HMO risk contractors serving Medicaid and
Medicare members. A practice that does not fall within an exception or a safe harbor is not necessarily unlawful, but may be subject to scrutiny and challenge. In the absence of an applicable exception or safe harbor, a violation of the statute may
occur even if only one purpose of a payment arrangement is to induce patient referrals or purchases of products or services that are reimbursed by federal health care programs. Among the practices that have been identified by the OIG as potentially
improper under the statute are certain product conversion programs in which benefits are given by drug manufacturers to pharmacists or physicians for changing a prescription, or recommending or requesting such a change, from one drug to another. The
Anti-Kickback Statute has been cited as a partial basis, along with state consumer protection laws discussed below, for investigations and multi-state settlements relating to financial incentives provided by drug manufacturers to retail pharmacies
as well as to PBMs in connection with such programs.

##### Table of Contents

Additionally, it is a crime under the Public Contractor Anti-Kickback Statute, for any person to
knowingly and willfully offer or provide any remuneration to a prime contractor to the United States, including a contractor servicing federally funded health programs, in order to obtain favorable treatment in a subcontract. Violators of this law
also may be subject to civil monetary penalties.

There have been a series of substantial civil and criminal investigations and
settlements, at the state and federal level, by pharmacy benefit managers over the last several years in connection with alleged kickback schemes. Such cases have included, among other things, allegations that PBMs inflated service fees charged to
pharmaceutical manufacturers and that PBMs made payments to customers allegedly intended to induce business. We are not a party in any such cases, and we believe that we are in substantial compliance with the legal requirements imposed by such
anti-remuneration laws and regulations. However, there can be no assurance that we will not be subject to scrutiny or challenge under such laws or regulations. Any such challenge could have a material adverse effect on our business, results of
operations, financial condition or cash flows.

Federal Statutes Prohibiting False Claims.

The Federal False Claims Act imposes civil penalties for knowingly making or causing to be made false claims with respect to governmental programs, such
as Medicare and Medicaid, for services not rendered, or for misrepresenting actual services rendered, in order to obtain higher reimbursement. Private individuals may bring qui tam or whistleblower suits against providers under the Federal
False Claims Act, which authorizes the payment of a portion of any recovery to the individual bringing suit. Such actions are initially required to be filed under seal pending their review by the Department of Justice. A few federal district courts
have recently interpreted the Federal False Claims Act as applying to claims for reimbursement that violate the anti-kickback statute or federal physician self-referral law under certain circumstances. The Federal False Claims Act generally provides
for the imposition of civil penalties and for treble damages, resulting in the possibility of substantial financial penalties for small billing errors that are replicated in a large number of claims, as each individual claim could be deemed to be a
separate violation of the Federal False Claims Act. Criminal provisions that are similar to the Federal False Claims Act provide that a corporation may be fined if it is convicted of presenting to any federal agency a claim or making a statement
that it knows to be false, fictitious or fraudulent.

There have been several qui tam actions filed under the Federal False Claims
Act, the Public Contractor Anti-Kickback Statute and similar state laws in various federal courts against several PBMs. The complaints allege, among other things, that such PBMs improperly favored the products of certain pharmaceutical manufacturers
over less expensive products and engaged in improper mail order pharmacy practices. For example, in October 2006, Medco Health Solutions entered into a $155 million civil settlement of claims under both state and federal false claims statutes that
it destroyed and canceled valid patient prescriptions, solicited kickbacks from pharmaceutical manufacturers to favor their drugs, and paid kickbacks to health plans to obtain business. Also, in September 2005, Caremark Inc. entered into a $137
million civil settlement of claims under both state and federal false claims statutes that its subsidiary, AdvancePCS, allegedly solicited and received kickbacks from pharmaceutical manufacturers in the form of excessive administrative fees,
over-priced services agreements as a reward for favorable formulary treatment, and improper flat fee rebates, and that AdvancePCS allegedly paid kickbacks to customers and potential customers to induce them to contract with AdvancePCS. Both Medco
and Caremark agreed to enter into 5-year corporate integrity agreements with the federal government in connection with their respective settlements.

Currently, we do not directly contract with the federal government to provide services to beneficiaries of federally funded health programs. Therefore, we do not directly submit claims to the federal government.
However, we do contract with and provide services to entities or organizations that are federal government contractors, such as Medicare Part D PDPs. There can be no assurance that the government would not potentially view one or more of our actions
in providing services to federal government contractors as causing or assisting in the presentment of a false claim. We do not believe we are in violation of the Federal False Claims Act and we have a corporate compliance and ethics program,
policies and procedures and internal controls in place to help maintain an organizational culture of honesty and integrity.

ERISA Regulation.

ERISA regulates certain aspects of employee pension and health benefit plans, including self-funded corporate health plans. We have agreements with self-funded corporate health plans to provide PBM services, and
therefore, we are a service provider to ERISA plans. ERISA imposes duties on any person or entity that is a fiduciary with respect to the ERISA plan. We administer pharmacy benefits for ERISA plans in accordance with plan design choices made by the
ERISA plan sponsors. We do not believe that the general conduct of our business subjects us to the fiduciary obligations set forth by ERISA, except when we have specifically contracted with an ERISA plan sponsor to accept fiduciary responsibility
and be named as a fiduciary for certain functions.

Numerous lawsuits have been filed against various PBMs by private litigants, whether by
a Plan participant on behalf of an ERISA plan or by the ERISA Plan sponsor, alleging that the PBMs are ERISA fiduciaries and that, in such capacity, they allegedly violated ERISA fiduciary duties in connection with certain business practices related
to their respective contracts with retail pharmacy networks and/or pharmaceutical manufacturers. For example, in 2004, Medco settled a lawsuit that alleged that Medco was a functional fiduciary under ERISA and violated its fiduciary obligations by,
among other things, failing to make adequate disclosures regarding certain rebates from pharmaceutical manufacturers and steering clients toward more expensive pharmaceuticals with higher rebates benefiting Medco and its then-parent company,
Merck & Co., Inc. Pursuant to the settlement, Medco agreed to pay $42.5 million into a settlement fund to be distributed to plan participants. In addition, Medco agreed to implement and continue certain business practices aimed at
increasing transparency around formulary decisions and therapeutic interchanges. Medco did not admit, and the settlement did not require Medco to admit, any wrongdoing under ERISA or otherwise.

Several recent cases further addressed the issue of whether a PBM is a fiduciary under ERISA. In an action brought against Caremark, Inc., a plan alleged
that Caremark violated its fiduciary duty under ERISA by hiding pricing spreads that yielded significant revenue for the PBM but was not passed on to the plan. In November 2007, the United States District Court for the Middle District of Tennessee
found that Caremark was not a fiduciary under ERISA because Caremark did not have discretion to unilaterally set prices for prescriptions and because the agreement between Caremark and the plan did not prohibit Caremark from negotiating with retail
pharmacies for favorable pricing. Similarly, in another action against Caremark, a multiemployer health fund alleged that Caremark breached its ERISA fiduciary duties by charging the fund higher prices for drugs than Caremark itself paid, as well as
for failing to pass on to the fund all price concessions that Caremark received from retailers and manufacturers. In January 2007, the Seventh Circuit found that Caremark was not a fiduciary because the fund possessed the sole authority to control
and administer prescription drug benefits and because Caremarks contracts with the fund provided that Caremark was not a fiduciary. In a case brought by a labor organization against its health plans PBM, Express Scripts, the United
States District Court for the Eastern District of Missouri held in July 2008 that Express Scripts was a fiduciary in connection with the payment of certain monies under a discontinued therapeutic substitution program, but that Express Scripts was
not a fiduciary with respect to MAC (generic drug) pricing, selecting the source for AWP (Average Wholesale Price) pricing, establishing formularies and negotiating rebates, or interest earned on rebates before the payment of the contracted client
share.

In those cases where we have not accepted fiduciary status, there can be no assurance that the U.S. Department of Labor, which is
the agency that enforces ERISA, or a private litigant would not assert that the fiduciary obligations imposed by the statute apply to certain aspects of our operations.

ERISA also imposes civil and criminal liability on service providers to health plans and certain other persons if certain forms of illegal remuneration are made or received. These provisions of ERISA are similar, but
not identical, to the federal healthcare Anti-Kickback Statute discussed above. In particular, ERISA does not provide the statutory and regulatory safe harbor exceptions incorporated into the federal healthcare Anti-Kickback Statute. Like the health
care anti-kickback laws, the corresponding provisions of ERISA are written broadly and their application to particular cases is often uncertain. We have implemented policies regarding, among other things, disclosure to health plan sponsors with
respect to any commissions paid by or to us that might fall within the scope of such provisions and accordingly believe we are in substantial compliance with these provisions of ERISA. However, we can provide no assurance that our policies in this
regard would be found by the appropriate enforcement authorities and potential private litigants to meet the requirements of ERISA.

##### Table of Contents

On December 13, 2007, the U.S. Department of Labor published proposed rules under ERISA that, if
made final, would redefine what constitutes a reasonable contract or arrangement exempt from the prohibited transaction provisions of ERISA. Essentially, the proposed rules require a written agreement between certain service providers
(such as a PBM) and an employee benefit plan that would require the disclosure of compensation arrangements so that the plan fiduciary can assess the reasonableness of the compensation and the potential for conflicts of interests that could affect
performance of the negotiated services. The proposed rules would also require that for a contract to be considered reasonable it must permit termination by the ERISA plan on reasonably short notice without penalty to prevent the plan from being
locked into a contract that has become disadvantageous, although the plan can be charged a fee on early termination to allow the service provider to recover start-up costs. The Department of Labor accepted comments on the proposed rules, and there
may be changes in response to those comments in the final rules, which have not yet been issued. Although we believe the proposed rules are not sufficiently specific in many technical regards, in principle, because of the transparent approach we
have taken in conducting our business, the disclosures already made, and the current marketplace regarding the length of contracts and pricing arrangements, we do not believe that complying with the proposed rules, should they become final in their
current form, would have a material adverse effect on our business, results of operations, financial condition or cash flows.

FDA Regulation.

The U.S. Food and Drug Administration, the FDA, generally has authority to regulate drug promotional materials that are
disseminated by or on behalf of a drug manufacturer. In January 1998, the FDA issued a Notice and Draft Guidance regarding its intent to regulate certain drug promotion and switching activities of PBMs that are controlled, directly or indirectly, by
drug manufacturers. After extending the comment period due to numerous industry objections to the proposed draft, the FDA has taken no further action on the Notice and Draft Guidance. However, there can be no assurance that the FDA will not attempt
again to assert jurisdiction over aspects of our business in the future and, although we are not controlled directly or indirectly by any drug manufacturer, the impact future FDA regulation could materially adversely affect our business, results of
operations, financial condition or cash flows.

Antitrust Regulation.

The federal antitrust laws regulate trade and commerce and prohibit unfair competition as defined by those laws. Section One of the Sherman Antitrust Act prohibits contracts, combinations or conspiracies in restraint
of trade or commerce. Despite its sweeping language, however, Section One of the Sherman Act has been interpreted to prohibit only unreasonable restraints on competition. Section Two of the Sherman Act prohibits monopolization and attempts at
monopolization. Similarly, Section Seven of the Clayton Act prohibits unlawful mergers and acquisitions. In addition, the Robinson Patman Act, which is part of the Clayton Act, prohibits a variety of conduct relating to the sale of goods, including
prohibiting practices the statute defines as price discrimination. One section of the Robinson Patman Act prohibits a seller from selling goods of like grade or quality to different customers at different prices if the favorable prices are not
available to all customers competing in the same class of trade. Successful plaintiffs in antitrust actions are allowed to recover treble damages for the damage sustained as a result of the violation.

Numerous lawsuits are pending against several PBMs and pharmaceutical manufacturers under various state and federal antitrust laws by retail pharmacies
throughout the United States challenging certain branded drug pricing practices. The complaints allege, in part, that the defendant PBMs accepted rebates and discounts from pharmaceutical manufacturers on purchases of brand-name prescription drugs
and conspired with other PBMs to fix prices in violation of the Robinson Patman Act and the Sherman Antitrust Act. The suits seek unspecified monetary damages, including treble damages, and injunctive relief. These cases are in various stages of
litigation. Several have been consolidated in multidistrict litigation with outcomes pending.

We believe that we are in substantial
compliance with the legal requirements imposed by such antitrust laws. However, there can be no assurance that we will not be subject to scrutiny or challenge under such legislation. To the extent that we appear to have actual or potential market
power in a relevant market, our business arrangements and practices may be subject to heightened scrutiny under the antitrust laws. Any such challenge could have a material adverse effect on our business, results of operations, financial condition
or cash flows.

Proposed Legislation.

Various bills in Congress address additional issues pertaining to drug pricing. For example, while the MMA currently prohibits the federal government from negotiating drug prices or establishing a preferred drug
formulary (i.e. the non-interference policy), several Congressional bills introduced in 2008 proposed varying degrees of federal government involvement in negotiating drug prices on behalf of Part D beneficiaries. Such bills, if passed,
could potentially materially impact our business. Other Congressional bills propose restricting PBMs in their ability to make certain drug interchanges, requiring PBMs annually to disclose all compensation received from drug manufacturers, and
requiring prompt payment of pharmacy claims under Part D. However, we do not at this time anticipate a material adverse impact from any of the proposed measures discussed in the prior sentence.

On January 20, 2009, Barack Obama became President of the United States. One of the significant issues that President Obama campaigned on was health
care reform. Currently, it is too early to speculate what such reform may look like, how it may impact our business, and when it may become effective. Therefore, at this time we are unable to predict whether there will be any effect,
positive or adverse, on our business as a result of the new Presidential administration.

State Laws and Regulations Affecting Our Business

The following descriptions identify various state laws and regulations that affect or may affect aspects of our business.

State Anti-Remuneration/False Claims Laws.

Several
states have laws and/or regulations similar to the federal healthcare Anti-Kickback Statute and Federal False Claims Act described above. Such state laws are not necessarily limited to services or items for which federally funded health care program
payments may be made. Such state laws may be broad enough to include improper payments made in connection with services or items that are paid by commercial payors. Both the 2006 Medco Health Solutions and 2005 Caremark Inc. settlements, discussed
above under Federal Statutes Prohibiting False Claims, included settlement of civil claims under several state false claims laws. Sanctions for violating these state anti-remuneration and false claims laws may include injunction,
imprisonment, criminal and civil fines and exclusion from participation in the state Medicaid programs. Additionally, under the Deficit Reduction Act of 2005, discussed in greater detail below, states are incentivized to pass broad false claims
legislation similar to the Federal False Claims Act.

We believe that we are in substantial compliance with the legal requirements imposed
by such laws and regulations. However, there can be no assurance that we will not be subject to scrutiny or challenge under such laws or regulations. Any such challenge could have a material adverse effect on our business, results of operations,
financial condition or cash flows.

State Consumer Protection Laws.

Most states have enacted consumer protection and deceptive trade laws that generally prohibit payments and other broad categories of conduct deemed harmful to consumers. These statutes may be enforced by states and/or
private litigants. Such laws have been and continue to be the basis for investigations, prosecutions, and settlements of PBMs, initiated by state prosecutors as well as by private litigants. For example, in February 2008, CVS Caremark Corporation
agreed to a settlement with 28 states attorneys general for $41 million to resolve allegations that CVS Caremark engaged in deceptive business practices by retaining the discounts and rebates obtained from switching patients to different brand-name
prescription drugs.

We believe that we are in substantial compliance with the legal requirements imposed by such laws and regulations.
However, no assurance can be given that we will not be subject to scrutiny or challenge under one or more of these laws, or under similar consumer protection theories.

State Comprehensive PBM Regulation.

States continue to introduce legislation to regulate PBM
activities in a comprehensive manner. Legislation seeking to impose fiduciary duties or disclosure obligations on PBMs has been proposed in some states. Both Maine



12



---

##### Table of Contents

and the District of Columbia have enacted statutes imposing fiduciary obligations on PBMs. However, the District of Columbia statute imposing fiduciary
duties on PBMs and requiring PBMs to disclose certain financial information, including the quantity of drugs purchased and the price paid by the PBM for such drugs, is involved in ongoing litigation and has not yet been implemented. The Maine
statute applies only to contracts entered into in Maine with respect to PBM customers, or covered entities in Maine. Under the Maine law, PBMs have a contractual fiduciary responsibility to pass through to their clients any price concessions
received from drug manufacturers that are associated with volume of sales or utilization of certain drug classes. The Maine law also requires PBMs to report all financial terms and arrangements for remuneration of any kind between the PBM and drug
manufacturer. Similarly, North Dakota, South Dakota and Vermont have relatively comprehensive PBM laws that, among other things, increase required financial transparency, and regulate therapeutic interchange programs.

Many states have licensure or registration laws governing certain types of ancillary health care organizations, including preferred provider
organizations, TPAs, companies that provide utilization review services and companies that engage in the practices of a pharmacy. The scope of these laws differs significantly from state to state, and the application of such laws to the activities
of PBMs often is unclear. Several other states, including Maryland, Mississippi, Louisiana, Connecticut and Tennessee, have recently eneacted laws regulating various PBM activities, and similar legislation is pending in several more states. Such
state laws do not appear to be having a material adverse effect on our business operations or our ability to negotiate and/or retain rebates and administrative fees from pharmaceutical manufacturers with respect to our customers in those states. We
believe that we currently maintain in good standing all such state licenses and registrations that we are required to hold. However, we can give no assurance that these and other states will not enact legislation with more adverse consequences in
the near future; nor can we be certain that future regulations or interpretations of existing laws will not adversely change the consequences experienced to date of existing laws.

In addition, certain quasi-regulatory organizations, including the National Association of Boards of Pharmacy, an organization of state boards of
pharmacy, the National Association of Insurance Commissioners, the NAIC, an organization of state insurance regulators, and URAC and the National Committee on Quality Assurance NCQA, both accreditation organizations, have
considered or have passed proposals to regulate PBMs and/or PBM activities, such as formulary development and utilization management. We maintain URAC accreditation for Drug Therapy Management as well as full accreditation as a PBM, which includes
evaluation of organizational quality, customer service, communications, disclosure of pricing policies, pharmaceutical distribution, drug utilization management, and pharmacy and therapeutics committees. In the summer of 2003, the NAIC adopted the
Health Carrier Prescription Drug Benefit Management Model Act which sets forth model provisions for states to regulate formularies and create an exceptions process to provide access to non-formulary medicines and avoid drug management
requirements such as step therapy. While the actions of the NAIC do not have the force of law, they may influence states to adopt requirements similar to the Model Act.

We believe that we are in substantial compliance with all such laws and requirements where required, and continue to monitor legislative and regulatory developments. There can be no assurance, however, regarding the
future interpretation of these laws and their applicability to the activities of our business. Future legislation or regulation, or interpretations by regulatory and quasi-regulatory authorities of existing laws and regulations, could materially
affect the cost and nature of our business as currently conducted.

Network Access Legislation.

A majority of states now have some form of legislation affecting our ability to limit access to a pharmacy provider network, referred to as any willing
provider legislation, or removal of a network provider, referred to as due process legislation. Such legislation may require us or our clients to admit any retail pharmacy willing to meet the plans price and other terms for network
participation, or may provide that a provider may not be removed from a network except in compliance with certain procedures. Similarly, there are any willing pharmacy provisions applicable to Medicare Part D plans with which we contract. These
statutes have not materially affected our business.

State Legislation Affecting Plan or Benefit Design.

Some states have enacted legislation that prohibits certain types of managed care plan sponsors from implementing certain restrictive design features, and
many states have legislation regulating various aspects of



13



---

##### Table of Contents

managed care plans, including provisions relating to the pharmacy benefits. For example, some states, under so-called freedom of choice legislation, provide
that members of the plan may not be required to use network providers, but must instead be provided with benefits even if they choose to use non-network providers. Other states have enacted legislation purporting to prohibit health plans from
offering members financial incentives for use of mail service pharmacies. Legislation has been introduced in some states to prohibit or restrict therapeutic intervention (including, without limitation, to carve out certain classes from generic
substitution), to require coverage of all FDA-approved drugs or to require coverage for off-label uses of drugs where those uses are recognized in peer-reviewed medical journals or reference compendia. Other states mandate coverage of certain
benefits or conditions and require health plan coverage of specific drugs, if deemed medically necessary by the prescribing physician. Such legislation does not generally apply to us directly, but may apply to certain of our clients, such as HMOs
and health insurers. If legislation were to become widely adopted, it could have the effect of limiting the economic benefits achievable through PBMs. This development could have a material adverse effect on our business, results of operations,
financial condition or cash flows.

State Regulation of Financial Risk Plans.

Fee-for-service prescription drug plans are generally not subject to financial regulation by the states. However, if a PBM offers to provide prescription
drug coverage on a capitated basis or otherwise accepts material financial risk in providing the benefit, laws in various states may regulate the plan. Such laws may require that the party at risk establish reserves or otherwise demonstrate
financial responsibility. Laws that may apply in such cases include insurance laws, HMO laws or limited prepaid health service plan laws. Currently, we do not believe that our business currently incurs financial risk of the type subject to such
regulation. However, if we choose to become a regional PDP for the Medicare outpatient prescription drug benefit at some time in the future, we would need to comply with state laws governing risk-bearing entities in the states where we operate a
PDP.

State Discount Drug Card Regulation.

Numerous states have laws and/or regulations regulating the selling, marketing, promoting, advertising or distributing of commercial discount drug cards for cash purchases. Such laws and regulations provide, generally, that any person may
bring an action for damages or seek an injunction for violations. We administer a limited commercial discount drug card program that we do not consider material to our business. We believe our administration of the commercial discount drug card
program is in compliance with various state laws. However, there can be no assurance that the existence of such laws will not materially impact our ability to offer certain new commercial products and/or services in the future.

Combined Federal and State Laws, Regulations and Other Standards Affecting Our Business

Certain aspects of our business are or may be affected by bodies of law that exist at both the federal and state levels and by other standard setting
entities. Among these are the following:

Deficit Reduction Act of 2005.

Under the Deficit Reduction Act of 2005, the DRA, the methodology used to determine federal upper payment limits, the maximum amount a state
can reimburse, for generic drugs under Medicaid was revised, stronger cost-sharing requirements applicable to Medicaid prescription drugs were permitted, and resources to reduce fraud, waste and abuse in the Medicaid program were increased. The
DRAs fraud, waste and abuse provisions, among other things, incentivized states to enact their own false claims acts, mirrored on the Federal False Claims Act, described above, and appropriate federal funding to increase scrutiny of the
Medicaid program. The fraud, waste and abuse provisions also included a provision intended to strengthen Medicaids status as payer of last resort relative to private health insurance by specifying that PBMs and self-insured plans may be liable
third parties. Although we do not contract directly with any state Medicaid programs, the provisions in the DRA have the potential to impact the PBM industry by means of increased prosecutorial and private litigant scrutiny of the pharmaceutical
industry in general, which may include PBMs. Additionally, the DRA mandated the public availability of pharmaceutical manufacturer average manufacturer prices, or AMPs, and created incentives to states to use AMPs for Medicaid
reimbursement, potentially paving the way for a more general market shift in reimbursement mechanisms from average wholesale price-based methodologies to AMP-based methodologies, discussed in more detail , below, under Legislation and
Litigation Affecting Drug Prices. Additionally, the third party recovery provisions in the DRA



14



---

##### Table of Contents

may lead to greater financial recoveries from third party PBMs in cases where Medicaid was not properly a primary payor on a drug claim, even where a PBM is
not financially at risk. DRA provisions regarding pharmacy restocking and double billing are discussed below in the section titled Laws and Regulations Affecting the Mail-Order Pharmacy Business.

Privacy and Confidentiality Legislation.

Our
activities involve the receipt or use of confidential medical information concerning individual members. In addition, we use aggregated and anonymized data for research and analysis purposes. Many state laws restrict the use and disclosure of
confidential medical information, and similar new legislative and regulatory initiatives are underway in several states. To date, no such laws adversely impact our ability to provide our services, but there can be no assurance that federal or state
governments will not enact such legislation, impose restrictions or adopt interpretations of existing laws that could have a material adverse effect on our business, results of operations, financial condition or cash flows.

The final privacy regulations, the Privacy Rule, issued by the DHHS pursuant to the Health Information Portability and Accountability Act,
HIPAA imposes extensive restrictions on the use and disclosure of individually identifiable health information by certain entities known under the Privacy Rule as covered entities. PBMs, in general, are not considered covered entities.
However, our mail order pharmacy is a covered entity and must comply with these restrictions. Additionally, our clients are covered entities, and are required to enter into business associate agreements with vendors, such as PBMs, that perform a
function or activity for the covered entity that involves the use or disclosure of individually identifiable health information. The business associate agreements mandated by the Privacy Rule create a contractual obligation for the PBM to perform
its duties for the covered entity in compliance with the Privacy Rule.

The final transactions and code sets regulation, the
Transaction Rule, promulgated under HIPAA requires that all covered entities that engage in electronic transactions use standardized formats and code sets. It is incumbent upon PBMs to conduct all such transactions in accordance with the
Transaction Rule to satisfy the obligations of their covered entity clients. DHHS promulgated a National Provider Identifiers, NPI, Final Rule which required large health plans to utilize NPIs in all Standard Transactions after
May 23, 2007 and required small health plans to utilize NPIs in all Standard Transactions after May 23, 2008. NPIs are intended to replace National Association of Boards of Pharmacy numbers for pharmacies, Drug Enforcement Agency numbers
for physicians and similar identifiers for other health care providers.

We have configured our systems to comply with the NPI Final Rule
and the Transaction Rule. The final security regulations, the Security Rule, issued pursuant to HIPAA mandate the use of administrative, physical and technical safeguards to protect the confidentiality of electronic health care
information. Similarly to the other two rules issued pursuant to HIPAA, the Security Rule applies to covered entities. We have made the necessary arrangements to ensure compliance with the Security Rule, as we are subject to many of its requirements
as a result of our contracts with covered entities.

Compliance with the Privacy Rule, the Transaction Rule and the Security Rule (the
HIPAA Regulations) has not had a material adverse effect on our business operations. Also, pursuant to HIPAA, state laws that are more protective of medical information are not pre-empted by HIPAA. Therefore, to the extent states enact
more protective legislation, we could be required to make significant changes to our business operations.

Independent of any regulatory
restrictions, individual health plan sponsor clients could increase limitations on our use of medical information, which could prevent us from offering certain services.

Legislation and Litigation Affecting Drug Prices.

Various federal and state Medicaid agencies, as
well as legislators and private litigants have raised the issue of how average wholesale price, AWP, is determined. AWP is a standard pricing unit published by third party data sources and currently used throughout the PBM industry as
the basis for determining drug pricing under contracts with clients, pharmacies and pharmaceutical manufacturers. Under MMA, AWP no longer serves as the basis for Medicare Part B Drug reimbursement, with certain limited exceptions. Rather, Part B
drugs generally are reimbursed on an average sales price, ASP, methodology. The ASP calculation methodology, which takes into account various discounts offered by drug manufacturers, may cause some drug manufacturers to reduce the levels



15



---

##### Table of Contents

of discounts or rebates available to PBMs or their clients with respect to Medicare Part B drugs. Drugs that are reimbursed on an ASP reimbursement system by
Medicare do not represent a significant portion of our business and we therefore do not believe that ASP reimbursement for such drugs will have a material adverse effect on our business, results of operations, financial condition or cash flows. The
extent to which ASP will be used in pricing outside the Medicare Part B context or changes to AWP state and federal programs could alter the calculation of drug prices for federal and/or state programs. We are aware that at least one state,
California, passed legislation in 2004 to implement a system to reimburse for Medicaid drugs using an ASP-based methodology, but such system has not yet been implemented. We are unable to predict whether any such changes will be adopted on a larger
scale, and whether such changes would have a material adverse effect on our business, results of operations, financial condition or cash flows.

As part of a proposed class action settlement in the case of New England Carpenters Health Benefits Fund v. First DataBank, in a federal court in Massachusetts, First DataBank, FDB, agreed to reduce the reported AWP of thousands
of specific pharmaceutical products by five percent. Additionally, FDB agreed to cease reporting AWPs for all pharmaceutical products within two years of the final settlement, with limited ability to resume publication of AWPs. In May 2007, Medispan
was named as a defendant in a substantially similar class action litigation involving the publication of AWP. Medispan similarly agreed to a proposed settlement under which Medispan would reduce the mark-up factor utilized in connection with the
calculation of its AWP data field and, ultimately, discontinue publication of its AWP data field for all drugs, subject to certain conditions. Although the Massachusetts federal court granted preliminary approval to settlements for both FDB and
Medispan in June 2007, opposition to approval was brought by both pharmacy and PBM associations, including the National Community Pharmacists Association (NCPA) and the Pharmaceutical Care Management Association (PCMA). In
January 2008, the court refused to grant final approval of the proposed settlement, and the litigation is ongoing. As of the close of December 2008, the settlement has not yet been approved.

According to the proposed settlement agreement, the AWP changes would take effect either 60 days after the effective date of the settlement agreement or
270 days from preliminary approval of the settlement. Except when our health plan clients mandate the use of AWP as reported by FDB, our contracts with pharmacies in our retail network and our health plan clients generally cite AWP as reported by
Medispan, National Drug Data file, as a pricing source for brand name and certain generic drugs. If the final approved settlement agreement includes Medispans proposed reductions in the AWP reported for specific pharmaceutical products, such
reduction could create disruption in our business due to the adverse impact on AWP-based pharmacy pricing and pharmacy efforts to negotiate another drug pricing measure, such as AMP or Wholesale Acquisition Cost. However, most of our contracts with
our clients and retail pharmacies contain terms that we believe will enable us to mitigate the adverse effect of any proposed reduction in reported AWP. If the final approved settlement includes reductions in reported AWP, we would exercise our
contractual rights so as to mitigate as far as practicable the adverse impact to us. Whatever the outcome of this case, we believe that payors, pharmacy providers and PBMs will begin to evaluate other pricing benchmarks as the basis for contracting
for prescription drugs and benefit management services in the future. We believe our business model can utilize one or more other consistently calculated benchmarks but we cannot evaluate the overall financial impact that the transition to any such
alternative benchmark might have. Due to these and other uncertainties, we can give no assurance that the short or long term impact of changes to industry pricing benchmarks will not have a material adverse effect on our financial performance,
results of operations, financial condition or cash flows in future periods.

The federal Medicaid rebate statute provides that
pharmaceutical manufacturers must provide rebates on all drugs purchased by the Medicaid program. Manufacturers of brand-name pharmaceuticals must provide the Medicaid program a rebate equivalent to the greater of (1) 15.1% of AMP the average
price for products sold to wholesalers, or (2) the difference between AMP and the best price given to customers other than the Medicaid program, with certain exceptions. We negotiate rebates with and services payments from drug manufacturers.
Investigations have been commenced by certain government agencies which question whether AMPs and best prices, and thus Medicaid rebates, were properly calculated, reported and paid by the manufacturers to the Medicaid programs. We are not
responsible for such calculations, reports or payments. Some pharmaceutical manufacturers may view the Medicaid rebate statute and/or the associated investigations as a disincentive to offer rebates and discounts to private parties, including PBMs
and this may adversely affect our ability to negotiate manufacturer rebates in the future.



16

##### Table of Contents

Additionally, in July 2007, CMS published final regulations intended to clarify the calculation of AMP
under the DRA, discussed above, as well as to require the publication of manufacturer AMPs. Prior to the issuance of these regulations, we understood that manufacturers took varying interpretations of the current law with respect to the treatment of
rebates and administrative fees paid to PBMs in the AMP calculation. Under the final AMP regulations, rebates paid to PBMs on sales through retail network pharmacies are excluded from manufacturers calculation of AMP. The final regulation also
excludes rebates on PBM retail network sales from the calculation of manufacturers best price. However, the regulation characterizes sales through a PBMs mail operation or specialty pharmacy as retail (i.e., as part of the retail
class of trade) and, therefore, as eligible for inclusion in AMP calculation. In addition, the regulation indicates that certain prices to PBMs may be excludable from manufacturers Best Price calculation. Further, CMS intends to post on
its web site monthly AMP data and the federal upper limits (FULs) derived from them for multiple source drugs, but these postings have been delayed in connection with the National Community Pharmacists Association and the National
Association of Chain Drug Stores litigation discussed below. The final AMP regulations could potentially affect our ability to negotiate manufacturer administrative fees and rebates in the future. Increased transparency resulting from the AMP
publication requirements imposed under the final regulation also could affect the rates at which our pharmacies are reimbursed and the rates our plans pay us for pharmacy claims, but we cannot predict at this time whether the affect of such possible
changes will be positive or negative. However, the final AMP regulation was preliminarily enjoined in December 2007, with respect to the public reporting of AMP and the use of AMP in the FUL determination, due to ongoing litigation by the National
Community Pharmacists Association and the National Association of Chain Drug Stores. Additionally, the regulation itself may be subject to change, at least with respect to the definition of AMP and the determination of FULs, as CMS formally accepted
comments on the final regulations.

In addition to these potential pricing developments on the federal level, some states have adopted
so-called most favored nation legislation providing that a pharmacy participating in the state Medicaid program must give the state the lowest price that the pharmacy makes available to any third-party plan. Such legislation may adversely affect our
ability to negotiate discounts in the future from network pharmacies.

Voluntary Industry Ethical Guidelines.

The Pharmaceutical Research and Manufacturers of America encourage its members to comply with a voluntary ethical code titled PhRMA Code On
Interactions with Healthcare Professionals. This code, which is generally voluntary but has the force of law in California, Massachusetts, and Nevada, provides guidance relating to several facets of pharmaceutical manufacturers marketing
practices, particularly with respect to payments to providers. Although the PhRMA Code was revised, recently, we believe that these ethical guidelines do not have a material adverse effect on our business, results of operations, financial operations
or cash flows.

Future Regulation.

We
are unable to predict accurately what additional federal or state legislation or regulatory initiatives may be enacted in the future relating to our businesses or the health care industry in general, or what effect any such legislation or
regulations might have on us. For example, the federal government and several state governments have proposed Patients Bill of Rights or other similar legislation aimed primarily at improving quality of care provided to individuals in managed
care plans. Some of the initiatives propose providing greater access to drugs not included on health plan formularies, giving participants the right to sue their health plan for malpractice, and mandating an appeals or grievance process. There can
be no assurance that federal or state governments will not impose additional restrictions, via a Patients Bill of Rights or otherwise, or adopt interpretations of existing laws that could have a material adverse effect on our business, results
of operations, financial condition or cash flows.

Laws and Regulations Specifically Related to Our Mail Order Pharmacy Operations

We operate mail order facilities in Alabama and Ohio for certain of our customers. The Alabama facility principally fills hospice-related prescriptions.
The Ohio facility fills prescriptions for all other clients electing to be served by that facility. Through December 2008, we operated a mail order pharmacy facility in Ft. Lauderdale, Florida that filled prescriptions primarily for workers
compensation and hospice accounts. The Florida facility is now closed, with its services consolidated in Alabama and Ohio. In addition to laws and regulations discussed above that may affect mail order pharmacy operations, we are subject to state
and federal statutes and regulations governing the operation of pharmacies, repackaging of drug products and dispensing of controlled substances.



17



---

##### Table of Contents

Regulation of Controlled Substances.

Our mail order facilities must register with the United States Drug Enforcement Administration and individual state controlled substance authorities in order to dispense controlled substances. Federal law requires us
to comply with the DEAs security, recordkeeping, inventory control, and labeling standards in order to dispense controlled substances. State controlled substance law requires registration and compliance with state pharmacy licensure,
registration or permit standards promulgated by the state pharmacy licensing authority.

State Licensure Laws.

We are licensed to do business as a pharmacy in Ohio and Alabama, and as a non-resident pharmacy in each state where registration with the state board of
pharmacy or similar governing body is required so that pharmaceuticals may be delivered by mail into the state. Also, some states require that an out-of-state pharmacy employ a pharmacist that is licensed in the state into which pharmaceuticals are
shipped. We believe we are in substantial compliance with state licensure and registration requirements with respect to our mail order facilities.

Other Regulations.

The federal Deficit Reduction Act of 2005 explicitly prohibits the restocking and double billing of
prescription drugs in connection with the Medicaid Program. Additionally, the Federal Trade Commission, referred to as FTC, regulates advertising by mail order pharmacies and requires such facilities to stock a reasonable supply of a
product sold, to fill mail orders within 30 days and to provide customer refunds where appropriate. In addition, the FDA sets standards for the packaging of prescription drugs. Federal and state anti-remuneration laws also apply to our mail order
pharmacy. We believe we are in substantial compliance with state and federal requirements pertaining to our mail order pharmacy operations.

Employees

As of December 31, 2008, we had 820 employees whose services are devoted full time to Catalyst Health Solutions and its
subsidiaries. We have never had a work stoppage. Our personnel are not represented by any collective bargaining unit. We consider our relations with our personnel to be good. Our future success will depend, in part, on our ability to continue to
attract, retain and motivate highly qualified technical and managerial personnel, for whom competition is intense.



|ITEM 1A. | RISK FACTORS
|-------- | ------------

Global Economic Conditions

If declining global economic conditions persist, our business, results of operations, financial condition or cash flows could suffer.

Recent global market and economic conditions have been unprecedented and challenging with tighter credit conditions and recession in most major economies
continuing into 2009. Continued concerns about the systemic impact of potential long-term and wide-spread recession, energy costs, geopolitical issues, the availability and cost of credit, and the global housing and mortgage markets have contributed
to increased market volatility and diminished expectations for western and emerging economies. In the second half of 2008, added concerns fueled by the U.S. government conservatorship of the Federal Home Loan Mortgage Corporation and the Federal
National Mortgage Association, the declared bankruptcy of Lehman Brothers Holdings Inc., the U.S. government financial assistance to American International Group Inc., Citibank, Bank of America and other federal government interventions in the U.S.
financial system lead to increased market uncertainty and instability in both U.S. and international capital and credit markets. These conditions, combined with volatile oil prices, declining business and consumer confidence and increased
unemployment, have contributed to volatility of unprecedented levels.

As a result of these market conditions, the cost and availability of
credit has been and may continue to be adversely affected by illiquid credit markets and wider credit spreads. Concern about the stability of the markets generally and the strength of counterparties specifically has led many lenders and
institutional investors to reduce,



18

##### Table of Contents

and in some cases, cease to provide credit to businesses and consumers. These factors have lead to a decrease in spending by businesses and consumers alike,
and a corresponding decrease in global infrastructure spending. Continued turbulence in the U.S. and international markets and economies and prolonged declines in business consumer spending may adversely affect our business to the extent it impacts
the liquidity and financial condition of our customers as well as may affect our results of operations, financial condition or cash flows.

Risks
Related To Our Business

Government efforts to reduce health care costs and alter health care financing practices could lead to a decreased demand
for our services and to reduced rebates from manufacturers.

On January 20, 2009, Barack Obama became President of the United
States, representing a change from a Republican to a Democratic administration and an alignment of power between the Legislative and Executive branches of government. Under the new presidential administration, it is possible that there could be
significant changes to the health care system in the United States. Possible changes could include increased governmental involvement in health care and PBM services and may otherwise change the way our clients do business. Our clients and
prospective clients may react to such proposals and the uncertainty surrounding them by reducing or delaying the purchase of our PBM services, and manufacturers may react by reducing rebates or reducing supplies of certain products. Such proposals
could lead to a decreased demand for our services and to reduced rebates from manufacturers. The potential scope of proposals by the new administration is not clear at this time, and thus we are unable to predict whether the new administration will
have a positive, neutral or adverse effect on our business.

In addition, both Congress and state legislatures are expected to consider
legislation to increase governmental regulation of managed care plans. Some of these initiatives would, among other things, require that health plan members have greater access to drugs not included on a plans formulary and give health plan
members the right to sue their health plans for malpractice when they have been denied care. The scope of the managed care reform proposals under consideration by Congress and state legislatures and enacted by states to date vary greatly, and we
cannot predict the extent of future legislation. However, these initiatives could greatly constrain our business practices and impair our ability to serve our clients.

Competition in our industry is intense and could reduce or eliminate our profitability.

The
PBM industry is very competitive. PBM companies compete primarily on the basis of price, service, reporting capabilities and clinical services. If we do not compete effectively, our business, results of operations, financial condition or cash flows
could suffer. The industry is highly consolidated and dominated by a few large, profitable, well-established companies with significantly greater financial and marketing resources, purchasing power and other competitive advantages, which we do not
have. Scale is a particularly important factor in negotiating prices with pharmacies and drug manufacturers. A limited number of firms, including national PBM companies such as Medco Health Solutions, Inc., Express Scripts, Inc., and CVS Caremark,
Inc., have an aggregate market share of approximately 70% of prescription volume. Our competitors also include drug retailers, physician practice management companies, and insurance companies/health maintenance organizations. Some of our services,
such as disease management services, informed decision counseling services and medical information management services, also compete with those being offered by pharmaceutical manufacturers, specialized disease management companies and information
service providers. We may also experience competition from other sources in the future.

If we lose key clients as a result of competitive bidding
for contracts, contract renewals, consolidation of clients or otherwise, our business, profitability and growth prospects could suffer.

We depend on a limited number of clients for a significant portion of our revenue. Our top ten clients generated approximately 64% of our revenue in 2008, including approximately 18% from Wellmark Blue Cross Blue Shield of Iowa and
approximately 12% from the State of Maryland. Our business, results of operations, financial condition or cash flows could suffer if we were to lose any of our significant clients.

Many of our clients put their contracts out for competitive bidding prior to expiration. Competitive bidding requires costly and time-consuming efforts
on our behalf and, even after we have won such bidding processes, we can incur significant expense in proceedings or litigation contesting the adequacy or fairness of these bidding processes. We could lose clients if they cancel their agreements
with us, if we fail to win a competitive bid at the



19

##### Table of Contents

time of contract renewal, if the financial condition of any of our clients deteriorates or if our clients are acquired by, or acquire, companies with which
we do not have contracts. Over the past several years, self-funded employers, TPAs and other managed care companies have experienced significant consolidation. Consolidations by their very nature reduce the number of clients who may need our
services. A client involved in a merger or acquisition by a company that is not a client of ours may not renew, and in some instances may terminate, its contract with us. Our clients have been and may continue to be, subject to consolidation
pressures.

If we lose pharmacy network affiliations, our business, results of operations, financial condition or cash flows could suffer.

Our operations are dependent to a significant extent on our ability to obtain discounts on prescription purchases from retail pharmacies
that can be utilized by our clients and their members. Our contracts with retail pharmacies, which are non-exclusive, are generally terminable by either party on short notice. If one or more of our top pharmacy chains elects to terminate its
relationship with us or if we are only able to continue our relationship on terms less favorable to us, access to retail pharmacies by our clients and their health plan members, and consequently our business, results of operations, financial
condition or cash flows could suffer. In addition, several large retail pharmacy chains either own or have strategic alliances with PBMs or could attempt to acquire or enter into these kinds of relationships in the future. Ownership of, or alliances
with, PBMs by retail pharmacy chains, particularly large pharmacy chains, could have material adverse effects on our relationships with those retail pharmacy chains, particularly the discounts they are willing to make available, and on our business,
results of operations, financial condition or cash flows.

If we lose relationships with one or more key pharmaceutical manufacturers or if rebate
payments we receive from pharmaceutical manufacturers decline, our business, results of operations, financial condition or cash flows could suffer.

We receive rebates from numerous pharmaceutical manufacturers based on the use of selected drugs by members of health plans sponsored by our clients, as well as fees for other programs and services. We believe our
business, results of operations, financial condition or cash flows could suffer if:



| |  |  | we lose relationships with one or more key pharmaceutical manufacturers;
| | - |  | ------------------------------------------------------------------------



| |  |  | we are unable to finalize rebate contracts with one or more key pharmaceutical manufacturers for 2009 or are unable to negotiate interim arrangements;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | rebates decline due to the failure of our health plan sponsors to meet market share or other thresholds;
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | legal restrictions are imposed on the ability of pharmaceutical manufacturers to offer rebates or purchase our programs or services;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------



| |  |  | pharmaceutical manufacturers choose not to offer rebates or purchase our programs or services; or
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | rebates decline due to contract branded products losing their patents.
| | - |  | ----------------------------------------------------------------------

Over the next few years, as patents expire covering many brand name drugs that currently have a substantial market share, generic products will be
introduced that may substantially reduce the market share of these brand name drugs. Historically, manufacturers of generic drugs have not offered formulary rebates on their drugs. Our profitability could be adversely affected if the use of newly
approved, brand name drugs added to formularies does not offset any decline in use of brand name drugs whose patents expire.

Changes in industry
pricing benchmarks could adversely affect our financial performance.

Contracts in the prescription drug industry, including our
contracts with our retail pharmacy networks and with our PBM clients, as well as our mail order pharmacy reimbursement rates, generally use certain published benchmarks to establish pricing for prescription drugs. These benchmarks include AWP, AMP
and Wholesale Acquisition Cost, referred to as WAC. Most of our contracts utilize the AWP standard. Recent events, including litigation involving FirstDatabank and Medispan, have raised uncertainties as to whether payors, pharmacy
providers, PBMs and others in the prescription drug industry will continue to utilize AWP as it has previously been calculated or whether other pricing benchmarks will be adopted for establishing prices within the industry.

Additionally, CMS regulations regarding the Medicaid AMP calculation could potentially impact our ability
to negotiate rebates and discounts, as well as our retail pharmacy network and mail order pricing and PBM client contracts. Because the status of certain aspects of the CMS regulation remains uncertain pending the outcome of industry challenges to
the regulation, we are unable to predict whether and to what extent the CMS AMP regulation will impact our business. Thus far, our business has not been materially adversely affected by the AMP regulations.

These matters are discussed in detail under BusinessGovernment Regulation/Legislation and Litigation Affecting Drug Price,
above. We believe that payors, pharmacy providers and PBMs will begin to evaluate other pricing benchmarks as the basis for contracting for prescription drugs and benefit management services in the future.

Due to these and other uncertainties, we can give no assurance that the short or long term impact of changes to industry pricing benchmarks will not have
a material adverse effect on our financial performance, results of operations, financial condition or cash flows in future periods.

If our business
continues to grow rapidly and we are unable to manage this growth, our business, results of operations, financial condition or cash flows could suffer.

Our business has grown rapidly since 2000, in part due to acquisitions, with total annual PBM revenue increasing from $4.9 million in 2000 to $2.5 billion in 2008. Our business strategy is to continue to seek to
expand our operations, including through possible acquisitions. If we are unable to finance continued growth, manage future expansion or hire and retain the personnel needed to manage our business successfully, then our business, results of
operations, financial condition or cash flows could be adversely affected. Our growth in operations has placed significant demands on our management and other resources, which is likely to continue. Under these conditions, it is important for us to
retain our existing management and to attract, hire and retain additional highly skilled and motivated officers, managers and employees.

If we are
unable to manage potential problems and risks related to future acquisitions, our business, results of operations, financial condition or cash flows could suffer.

Part of our growth strategy includes making acquisitions involving new markets and complementary products, services, technologies and businesses. If we are unable to overcome the potential problems and inherent risks
related to such future acquisitions, our business, results of operations, financial condition or cash flows could suffer. Our ability to continue to expand successfully through acquisitions depends on many factors, including our ability to identify
acquisition prospects and negotiate and close transactions. Even if we complete future acquisitions:



| |  |  | we could fail to successfully integrate the operations, services and products of an acquired company;
| | - |  | -----------------------------------------------------------------------------------------------------



| |  |  | there could be inconsistencies in standards, controls, procedures and policies among the companies being combined or assimilated which would make it more difficult
to implement and harmonize company-wide financial, accounting, billing, information technology and other systems;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we may experience difficulties maintaining the quality of products and services that acquired companies have historically provided;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------



| |  |  | we could be required to amortize the identifiable intangible assets of an acquired business, which will reduce our net income in the years following its
acquisition, and we also would be required to reduce our net income in future years if we were to experience an impairment of goodwill or other intangible assets attributable to an acquisition;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | we could be exposed to unanticipated liabilities of acquired businesses;
| | - |  | ------------------------------------------------------------------------



| |  |  | our managements attention could be diverted from other business concerns; and
| | - |  | ------------------------------------------------------------------------------



| |  |  | we could lose key employees or customers of the acquired business.

There are risks associated with integrating and operating newly acquired businesses. We can give no
assurance that if we do acquire any new business organizations in the future, we will successfully operate and integrate them. Many companies compete for acquisition opportunities in the PBM industry. Most of our competitors are companies that have
significantly greater financial and management resources than we do. This may reduce the likelihood that we will be successful in completing acquisitions necessary to the future success of our business.

If we become subject to liability claims that are not covered by our insurance policies, we may be liable for damages and other expenses that could have a material
adverse effect on our business, results of operations, financial condition or cash flows.

Various aspects of our business may
subject us to litigation and liability for damages. These include the performance of PBM services and the operation of our call centers and Web site. A successful product or professional liability claim in excess of our insurance coverage where we
are required to pay damages, incur legal costs or face negative publicity could have a material adverse effect on our business, results of operations, financial condition or cash flows, our business reputation and our ability to attract and retain
clients, network pharmacies, and employees. While we intend to maintain professional and general liability insurance coverage at all times, we cannot provide assurances that we will be able to maintain insurance in the future, that insurance will be
available on acceptable terms or that insurance will be adequate to cover any or all potential product or professional liability claims.

Disruption
of our point of sale information system and transaction processing system, which relies on third parties, could have a material adverse effect on our business, results of operations, financial condition or cash flows.

Our operations utilize an electronic network connecting over 61,000 retail pharmacies to process third-party claims. This system is provided by a
third-party adjudication vendor. Because claims are adjudicated in real time, systems availability and reliability are key to meeting customers service expectations. Any interruption in real time service, either through systems availability or
telecommunications disruptions can significantly damage the quality of service we provide. Our PBM services also depend on third-party proprietary software to perform automated transaction processing. There can be no assurance that our business will
not be harmed by service interruptions or software performance problems.

The failure by our health plan clients to pay for prescription claims or a
delay in payment of those claims could have a material adverse effect on our business, results of operations, financial condition or cash flows.

Our contracts with retail pharmacies which participate in our network generally obligate us to make payments for prescription claims even if we are not reimbursed by our clients. If our clients delay their
reimbursement payments or fail to make payments for prescription claims, it could have a material adverse effect on our business, results of operations, financial condition or cash flows.

If we fail to comply with complex and rapidly evolving laws and regulations, we could suffer civil and/or criminal penalties, lose clients, be required to pay
substantial damages and make significant changes to our operations.

During the past several years, the U.S. health care industry
has been subject to an increase in governmental regulation at both the federal and state levels. We are subject to numerous federal and state regulations. If we fail to comply with existing or future applicable laws and regulations, we could suffer
civil or criminal penalties. We must devote significant operational and managerial resources to comply with these laws and regulations. Although we believe that we substantially comply with all existing statutes and regulations applicable to our
business, different interpretations and enforcement policies of these laws and regulations could subject our current practices to allegations of impropriety or illegality or could require us to make significant changes to our operations. In
addition, we cannot predict the impact of future legislation and regulatory changes on our business or assure you that we will be able to obtain or maintain the regulatory approvals required to operate our business.

Among the legislation and government regulations that could affect us as a provider of PBM services are the regulatory matters discussed in detail in
under BusinessGovernment Regulation, above.

We are subject to potential lawsuits under ERISA and the potential liabilities associated with being found to be a
fiduciary of a health plan governed by ERISA.

As a service provider to ERISA plans, we are subject to potential litigation under
ERISA claims and could face potential liabilities if we are found to be acting as a fiduciary of a plan in carrying out the services for which we are under contract. While we do not believe that the general conduct of our business subjects us to the
fiduciary obligations set forth by ERISA, except when we have specifically contracted with an ERISA plan sponsor to accept fiduciary responsibility and be named as a fiduciary for certain functions, recent litigation has revealed uncertainties with
respect to whether, and under what circumstances, courts will find PBMs to be acting as plan fiduciaries. The potential impact of ERISA liability on our business operations is more fully described in the detailed discussion of ERISA regulation under
BusinessGovernment RegulationFederal Laws and Regulations Affecting the PBM Business/ ERISA Regulation, above.

The
MMA subjects us to certain regulations and scrutiny, even in our limited roles as a subcontractor and mail service provider to Part D Plans.

There are many uncertainties presented by the MMA, which is one of the reasons we have opted not to directly sponsor a PDP. However, we do contract with Medicare Part D Plans, as described under
BusinessGovernment Regulation, above. In the limited capacity of a subcontractor and as a mail service provider, we are indirectly subject to certain regulatory requirements, as more fully described in the detailed discussion of
the MMA and its potential implications under BusinessGovernment Regulation, above.

We lease twenty-five facilities
throughout the United States and Puerto Rico. Our corporate headquarters office, containing 75,000 square feet, is located in Rockville, Maryland and accommodates our executive and corporate functions. We also have satellite offices in Alabama,
Arizona, California, Florida, Georgia, Hawaii, Iowa, Louisiana, Mississippi, Nevada, New Mexico, North Carolina, Ohio, Pennsylvania, Puerto Rico and Texas. We believe all of our facilities are well-maintained and in good operating condition and have
adequate capacity to meet our current business needs.

Twenty-one of our twenty-four satellite offices, with a total of 161,000 square
feet, are under leases that expire over terms through 2018 and the other offices are under a month-to-month lease. We believe that suitable space on commercially reasonable terms will be available as required.



|ITEM 3. | LEGAL PROCEEDINGS
|------- | -----------------

From time to time we become
subject to legal proceedings and claims in the ordinary course of business. Such claims, even if without merit, could result in the significant expenditure of our financial and managerial resources. We are not aware of any legal proceedings or
claims that we believe will, individually or in the aggregate, materially harm our business or have a material adverse effect on our financial condition, results of operations or cash flows.

COMPANY OVERVIEW

Catalyst Health Solutions, Inc. (formerly HealthExtras, Inc.) is a full-service pharmacy benefit management, or PBM, company. We operate primarily
under the brand name Catalyst Rx. Our clients include self-insured employers, including state and local governments; managed care organizations; unions; third-party administrators; referred to as TPAs; hospices; and individuals who contract with us
to administer the prescription drug component of their overall health benefit programs.

We provide our clients access to a contracted,
non-exclusive national network of approximately 61,000 pharmacies. We provide our clients members with timely and accurate benefit adjudication, while controlling pharmacy spending trends through customized plan designs, clinical programs,
physician orientation programs, and member education. We use an electronic point-of-sale system of eligibility verification and plan design information, and offer access to rebate arrangements for certain branded pharmaceuticals. When a member of
one of our clients presents a prescription or health plan identification card to a retail pharmacist in our network, the system provides the pharmacist with access to online information regarding eligibility, patient history, health plan formulary
listings, and contractual reimbursement rates. The member generally pays a co-payment to the retail pharmacy and the pharmacist fills the prescription. We electronically aggregate pharmacy benefit claims, which include prescription costs plus our
claims processing fees for consolidated billing and payment. We receive payments from clients, make payments of amounts owed to the retail pharmacies pursuant to our negotiated rates, and retain the difference (except where we have entered into
pass-through pricing arrangements with clients) including claims processing fees. Total claims processed increased to 52.0 million in 2008 from 41.5 million in 2007. Our revenue increased by 37% to approximately $2.5 billion in 2008 from
$1.9 billion in 2007.

Pharmacy benefit claims payments from our clients are recorded as revenue, and prescription costs to be paid to
pharmacies are recorded as direct expenses. Under our network contracts, we generally have an independent obligation to pay pharmacies for the drugs dispensed and, accordingly, have assumed that risk independent of our clients. When we administer
pharmacy reimbursement contracts and do not assume a credit risk, we record only our administrative or processing fees as revenue. Rebates earned under arrangements with manufacturers are recorded as a reduction of direct expenses. The portion of
manufacturer rebates due to clients is recorded as a reduction of revenue.

Member co-payments are not recorded as revenue or direct
expenses. We incur no obligations for co-payments to pharmacies and have never made such payments. Under our pharmacy agreements, the pharmacy is solely obligated to collect the co-payments from the members.

If we had included co-payments in our reported revenue and direct expenses, it would have resulted in an increase in our reported revenue and direct
expenses of $753.5 million, $635.6 million, and $477.0 million, for the years ended December 31, 2008, 2007 and 2006, respectively. Our operating and net income, consolidated balance sheets and statements of cash flows would not have been
affected.

SFAS No. 131, Disclosures about Segments of an Enterprise and Related Information,
establishes standards for the way that public enterprises report information about operating segments in financial statements. We have determined that we operate in only one segmentthe pharmacy benefits management, or PBM, segment.

RECENT DEVELOPMENTS

In December
2008, we formed an entity called First Rx Specialty and Mail Services, LLC and extended existing contracts with Walgreen Co. to provide certain mail and specialty pharmacy services. This initiative is designed to provide enhanced capabilities in the
distribution of specialty drugs, invest in various member-focused programs to deliver care-effective and cost-effective drugs to our customers, and access the Walgreens network of mail service pharmacies for over-flow mail volume, back-up, and
redundancy.

As a part of this arrangement, we received $7.0 million in cash. We have considered the accounting for the investment and the
contract extension and have recorded a liability in our consolidated balance sheet at December 31, 2008, pursuant to Financial Accounting Standard No. 150, Accounting for Certain Financial Instruments with Characteristics of both
Liabilities and Equity. We are also recognizing expense associated with the accretion of $1.0 million in other value to an ultimate redemption value of $8.0 million. We have a contractual obligation to redeem the total investment in cash in
the year 2013.

ACQUISITIONS

We have supported the growth of our business through acquisitions. We strive to timely integrate our acquisitions into our financial, organizational, management and technology structure. When successfully integrated, we expect to achieve
cost savings from the consolidation of certain corporate activities and the elimination of certain duplicate components of our corporate operations.

Acquisition of Immediate Pharmaceutical Services, Inc.

On August 5, 2008, we acquired Immediate Pharmaceutical
Services, Inc. (IPS) from Discount Drug Mart, Inc. IPS operates a fully-integrated prescription mail service fulfillment center located outside of Cleveland, Ohio. The IPS acquisition provides us with a foundation for building our mail
service capability and to enable us to provide our clients with an in-house mail service option. Total consideration for the acquisition of IPS consisted of cash payments of $40.0 million and approximately $1.2 million in transaction costs. The
purchase price of IPS was largely determined on the basis of managements expectations of future earnings and cash flows, resulting in the recognition of goodwill. Based on managements best estimate, the acquisition of IPS resulted in
goodwill of $24.2 million and customer relationship intangibles of $6.0 million. Goodwill related to this acquisition is non-deductible for tax purposes.

Acquisition of HospiScript Services, LLC

On May 16, 2008, we acquired HospiScript Services, LLC and Concept
Pharmaceuticals, LLC, a related party to HospiScript Services through common ownership (collectively, HospiScript). HospiScript provides pharmacy medication therapy management services to the hospice industry.

##### Table of Contents

Total consideration for the acquisition of HospiScript consisted of cash payments of $102.7 million and
$0.4 million in transaction related costs. Additionally, the acquisition provides for possible contingent consideration payments through 2010 of up to $8.1 million, subject to specified operating performance standards, of which approximately $0.9
million was earned in 2008. Contingent consideration earned is accounted for as additional goodwill.

The purchase price of HospiScript was
determined on the basis of managements expectations of future earnings and cash flows, resulting in the recognition of goodwill. Based on managements best estimate, including our valuation report of the allocation of the purchase price
to the net assets acquired, the acquisition of HospiScript resulted in goodwill of $79.4 million and intangibles assets, consisting of customer relationships of $18.6 million with an estimated 18 year life, trade names of $1.4 million with an
estimated 3.5 year life, and developed technology of $0.6 million with an estimated 5 year life. Goodwill related to this acquisition is deductible for tax purposes.

Acquisition ofR/xx

In November 2006, the Company purchased all
of the outstanding common stock of R/xxPharmacy Solutions, Inc. (R/xx), an Arizona corporation, for $16.0 million in cash and $0.7 million in related transaction costs. Pursuant to the acquisition agreement, additional cash consideration of $2.1 million was earned and paid in
2007 based on successful achievement of certain client retention criteria and recorded as additional goodwill. R/xxis a provider of pharmacy
benefit management services with a strategic focus on clients in the Arizona, Nevada and Hawaii markets.

Acquisition of EBRx

In December 2005, the Company acquired the common stock of EBRx. Consideration consisted of a cash payment of $27.9 million and $0.9 million in related
transaction costs. Pursuant to the acquisition agreement, additional cash consideration of $2.9 million was earned and paid through 2007 based on successful achievement of certain performance based standards and recorded as additional goodwill.

In January 2006, as contemplated by the original transaction, a separate entity owned by former owners of EBRx and its management team
purchased a 20% ownership interest in the parent of EBRx through a $1.0 million equity investment. In February 2007, under the terms of the transaction, we acquired this remaining 20% minority ownership interest. This transaction resulted in a cash
payment of $30.3 million, of which $29.0 million was recorded as additional goodwill, prior to the repayment of certain related transaction debt and accrued interest. In May 2007, the related transaction debt of $1.0 million plus accrued interest of
$0.1 million was repaid.

Other acquisitions

To support its geographic expansion and growth, the Company has periodically completed various insignificant business acquisitions to secure local operating assets, new pharmacy network contracts and local market executive offices. None of
these transactions has had any significant impact on the Companys reported revenues, assets or results of operations.

RESULTS OF OPERATIONS

Year Ended December 31, 2008 Compared to Year Ended December 31, 2007

Revenue.
Revenue from operations for the year ended December 31, 2008 was approximately $2.5 billion. Revenue increased over the comparable period in 2007 by $685.7 million. Total claims processed increased to approximately 52.0 million in 2008
from approximately 41.5 million in 2007. Contributors to the increase in revenue and prescription volume were primarily due to our contracts with the State of Maryland and Ohio, which commenced on July 1, 2007, and Puerto Ricos MCS
Commercial business and MCS Medicare Part D business, which commenced on December 1, 2007 and January 1, 2008, respectively, as well as our acquisition of IPS and HospiScript.

Direct Expenses.Direct expenses for the years ended December 31, 2008 and 2007 were $2.4 billion and $1.7 billion, respectively. The
increase in direct expenses is primarily related to the $685.7 million increase in revenue. Direct expenses for 2008 and 2007 represented 97.3% and 97.0% of total operating expenses for the respective periods.

Gross margin, calculated as revenue less direct expenses, is generally predictable based on client contract terms and vendor/supplier contracts. Other
factors that can result in changes in gross margins include generic substitution rates, changes in the utilization of preferred drugs with higher discounts and changes in the volume of prescription dispensing at lower cost network pharmacies. None
of the foregoing factors materially changed in 2008 in a manner that would meaningfully affect current results. Gross margin increased to $143.3 million for the year ended December 31, 2008 from $110.4 million for the comparable period in 2007.

Gross margin as a percentage of revenue was 5.6% and 5.9% for the years ended December 31, 2008 and 2007, respectively. In 2008,
composite gross margin percentages were slightly reduced by the full year impact of the addition of several recent large contracts, including the state of Maryland and Ohio and the Puerto Rico based health plans, which are more competitively priced
due to their size. These decreases were somewhat offset by gross margin improvements resulting from an increased level of generic substitution and higher network discount rates.

Selling, General and Administrative.For the year ended December 31, 2008, selling, general and administrative expenses increased by
approximately $13.8 million over the prior year to $67.8 million or 2.7% of operating expenses. This increase was primarily associated with our growth and the associated personnel, facility and vendor costs to serve and implement new clients as well
as incremental selling, general and administrative costs related to our evaluation of various strategic opportunities and to our acquisition of IPS and HospiScript.

Selling, general and administrative expenses of $67.8 million for the year ended December 31, 2008, consisted of $34.1 million in compensation and benefits, which includes $5.2 million in non-cash compensation,
$6.3 million in professional fees and technology services, $8.4 million in facility costs, $3.3 million in travel expenses, $3.0 million in insurance and other corporate expenses, $4.1 million in other, which includes $1.2 million in recruitment and
temporary help, and $8.6 million in depreciation and amortization.

Selling, general and administrative expenses of $54.0 million for the
year ended December 31, 2007, consisted of $27.7 million in compensation and benefits, which includes $4.9 million in non-cash compensation, $5.5 million in professional fees and technology services, $5.6 million in facility costs, $2.7 million
in travel expenses, $2.3 in insurance and other corporate expenses, $0.3 million in product endorsement and marketing, $3.7 million in other, which includes $1.7 million in recruitment and temporary help, and $6.2 million in depreciation and
amortization.

Interest Income. Interest income decreased to $4.5 million for the year ended December 31, 2008 from $6.6
million for the year ended December 31, 2007. The decrease was primarily due to a decrease in average funds available for investment resulting from our business acquisitions during the year.

Interest Expense.Interest expense increased to $0.3 million for the year ended December 31, 2008 from $0.2 million for the year ended
December 31, 2007. The increase in interest expense was attributable to the net drawings on our line of credit during 2008. At December 31, 2008, we had available a $50.0 million revolving credit facility with no outstanding borrowings.

Minority Interest.The minority interest in 2007 represents 20% of the earnings of EBRx during the period in which there was a
minority interest outstanding.

##### Table of Contents

Income Tax Expense.The effective income tax rates of 36.7% in 2008 and 37.6% in 2007 represent
the combined federal and state income tax rates adjusted as necessary based on the particular jurisdictions where we operate. The effective tax rate in 2008 was lower than in 2007 primarily due to a decrease in our state effective tax rates.

Net Income.Net income for year ended December 31, 2008 increased by approximately $11.1 million over the same period in 2007
to $50.4 million. The increase in net income was primarily a function of increased gross margin dollars, reduced by an increase in selling, general and administrative expenses.

Year Ended December 31, 2007 Compared to Year Ended December 31, 2006

Revenue.
Revenue from operations for the year ended December 31, 2007 was approximately $1.9 billion compared to approximately $1.3 billion in the comparable period in 2006. Revenue increased over the comparable period in 2006 by $586.7 million. Total
claims processed increased to approximately 41.5 million in 2007 from approximately 29.3 million in 2006. Contributors to the increase in revenue and prescription volume were our contracts with Wellmark Blue Cross Blue Shield of Iowa,
covering over 1.0 million members, which commenced on July 1, 2006, and the States of Maryland and Ohio, which commenced on July 1, 2007. These contracts generated 29% of our consolidated revenue in 2007.

Direct Expenses.Direct expenses for the year ended December 31, 2007 were $1.7 billion compared to $1.2 billion in the comparable period in
2006. The increase in direct expenses was primarily related to the $586.7 million increase in revenue. Also included in the direct expenses for 2007 are charges of approximately $1.9 million reflective of the resolution of a previously disclosed
arbitration proceeding which stems from a prior acquisition, and related adjustments. The direct expenses of $1.7 billion and $1.2 billion for the years ended December 31, 2007 and 2006 represented 97.0% and 96.2% of total operating expenses
for the respective periods.

Gross margin, calculated as revenue less direct expense, is generally predictable based on client contract
terms and vendor/supplier contracts. Other factors that can result in changes in gross margins include generic substitution rates, changes in the utilization of preferred drugs with higher discounts and changes in the volume of prescription
dispensing at lower cost network pharmacies. None of the foregoing factors have materially changed in 2007 in a manner that would meaningfully affect current results. Gross margin increased to $110.4 million for the year ended December 31, 2007
from $94.1 million for the comparable period in 2006.

Gross margin as a percentage of revenue was 5.9% and 7.4% for the years ended
December 31, 2007 and 2006, respectively. In 2007, composite gross margin percentages were reduced by the addition of several new large contracts including Wellmark Blue Cross Blue Shield of Iowa and the State of Maryland, which are more
competitively priced due to their size. These decreases were somewhat offset by gross margin improvements resulting from an increased level of generic substitution and higher network discount rates.

Selling, General and Administrative.For the year ended December 31, 2007, selling, general and administrative expenses increased by
approximately $7.6 million over the prior year to $54.0 million or 3.0% of operating expenses. This increase was primarily associated with our growth and the associated personnel and vendor costs to serve and implement new clients.

Selling, general and administrative expenses of $54.0 million for the year ended December 31, 2007, consisted of $27.7 million in compensation and
benefits, which includes $4.9 million in non-cash compensation, $5.5 million in professional fees and technology services, $5.6 million in facility costs, $2.7 million in travel expenses, $2.3 in insurance and other corporate expenses, $0.3 million
in product endorsement and marketing, $3.7 million in other, which includes $1.7 million in recruitment and temporary help, and $6.2 million in depreciation and amortization. Included in the $27.7 million of compensation and benefits is
approximately $0.9 million of costs related to changes in employment relationships previously disclosed.

Selling, general and
administrative expenses of $46.4 million for the year ended December 31, 2006, consisted of $25.1 million in compensation and benefits, which includes $3.6 million in non-cash compensation, $4.1 million in professional fees and technology
services, $4.2 million in facility costs, $2.2 million in travel expenses, $2.0 in insurance and other corporate expenses, $0.3 million in product endorsement and marketing, $3.7 million in other, which includes $2.2 million in recruitment and
temporary help, and $4.8 million in depreciation and amortization.

Interest Income. Interest income increased to $6.6 million for the year ended December 31,
2007 from $5.1 million for the year ended December 31, 2006. The increase was primarily due to an increase in average funds available for investment during the period and an increase in the rate of return available in the marketplace.

Interest Expense.Interest expense decreased to $0.2 million for the year ended December 31, 2007 from $0.8 million for the
year ended December 31, 2006. This decrease reflects the decrease in the average outstanding amount of indebtedness during the periods. In September 2006, we fully repaid the balance outstanding on our term loan facility.

Minority Interest.Prior to February 6, 2007, EBRx was majority owned by us and 20% owned by investors affiliated with EBRxs former
parent. On February 6, 2007, we acquired the minority ownership interest. The minority interest represents 20% of the earnings of EBRx during the period in which there was an outstanding minority interest.

Income Tax Expense. The effective income tax rates of 37.6% in 2007 and 39.1% in 2006 represent the combined federal and state income tax rates
adjusted as necessary based on the particular jurisdictions where we operate. The effective tax rate in 2007 was lower than in 2006 primarily due to a decrease in our state income tax rates as well as additional interest income earned on federally
tax exempt investments.

Net Income.Net income for year ended December 31, 2007 increased by approximately $7.7 million over
the same period in 2006 to $39.3 million. The increase in net income was primarily a function of increased gross margin dollars and an increase in interest income, reduced by an increase in selling, general and administrative expenses.

LIQUIDITY AND CAPITAL RESOURCES

Our sources of funds are usually cash flows from operating activities. We have in the past also raised funds by borrowing on bank debt and selling equity in the capital markets to fund acquisitions; however, no assurances can be given that
we will be able to raise funds in light of present credit market conditions. During the last several years, we have generated positive cash flow from operations and anticipate similar results in 2009. At December 31, 2008, we had available a
$50.0 million revolving credit facility and our cash and cash equivalents were $55.0 million. The decrease of $26.0 million in our cash and cash equivalents since the end of fiscal 2007 resulted primarily from cash used for acquisitions offset by
cash generated from operations.

We have approximately $12.7 million at par value in investments related to auction rate securities (ARS),
all of which are classified as non-current at December 31, 2008. Our ARS are floating rate securities with longer-term maturities with auction reset dates from 7 to 35 day intervals. Beginning in February 2008, auctions for these securities
began to fail. We are unlikely to be able to access these funds until future auctions for these ARS are successful, or until we sell the securities in a secondary market which currently is not fully active, although there have been instances of
redemptions at par to date by issuers. As such, these investments currently lack short-term liquidity and are therefore classified as non-current on our December 31, 2008 balance sheet.

For each of our ARS, we evaluate the risks related to the structure, collateral and liquidity and estimate the fair value of the securities using a
discount model based on (a) the underlying structure of each security; (b) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions; and (c) considerations of the
probabilities of redemption or auction success for each period. Based on the results of these assessments, we recorded a temporary impairment charge of $1.1 million in the fourth quarter of 2008 to reduce the value of our ARS classified as
available-for-sale securities. If circumstances arise which would require us to change assumptions or the credit rating of the security issuer deteriorates, we may be required to adjust the carrying values of our available-for-sale ARS through an
other-than-temporary impairment charge in current period earnings.

Based on our cash and cash equivalents balance of $55.0 million,
our available $50.0 million revolving credit facility, and our positive operating cash flows, we do not anticipate a lack of liquidity associated with our ARS to have a material impact on our liquidity, financial condition, results of operations or
cash flows. We believe we have the ability to hold the securities until liquidity returns to the market, other secondary markets develop, or the securities mature. Nonetheless, where appropriate, we are actively exploring and pursuing alternatives
for obtaining relief from the unanticipated illiquidity of the ARS holdings, including seeking relief from entities involved in

investing our funds in ARS. As a part of these efforts, on February 23, 2009, we brought an arbitration claim before the Financial Industry
Regulatory Authority (FINRA) against Credit Suisse Securities (USA), LLC (Credit Suisse) seeking rescission, restitution and damages for Credit Suisses conduct in connection with our investment account with Credit
Suisse.

Net Cash Provided by Operating Activities.Our operating activities generated $78.6 million of cash from operations in 2008,
a $24.0 million increase from the $54.6 million generated in 2007. This $78.6 million in cash provided by operating activities in 2008 reflects $50.4 million in net income, plus $17.4 million in non-cash charges and $10.8 million net decrease in
working capital and other assets and liabilities. This $10.8 million net decrease in working capital was primarily due to a $49.5 million increase in accounts receivable offset by a $58.3 million increase in accounts payable and other current
liabilities. The increase in accounts receivable and accounts payable was primarily due to increases in our claims volume.

Our operating
activities generated $54.6 million of cash from operations in 2007, a $2.2 million increase from the $52.4 million generated in 2006. This $54.6 million in cash provided by operating activities in 2007 reflects $39.3 million in net income, plus
$12.7 million in non-cash charges and $2.6 million net increase in working capital and other assets and liabilities. This $2.6 million net increase in working capital was primarily due to a $54.2 million increase in accounts receivable and $5.2
million increase in income tax receivable offset by a $64.1 million increase in accounts payable and other current liabilities. The cash provided by operating activities of $52.4 million in 2006 reflects net income of $31.6 million, plus $11.4
million in non-cash charges, and a net $9.4 million decrease in working capital and other assets and liabilities.

Net Cash Used in
Investing Activities.Net cash used in investing activities for the year ended December 31, 2008 was $120.3 million compared to $38.4 million in 2007. During 2008, approximately $142.4 million of cash was used relating to business
acquisitions. Additionally, during 2008, we had $8.7 million in capital expenditures and net sales of marketable securities of $30.9 million.

Net cash used in investing activities for the year ended December 31, 2007 was $38.4 million
compared to $36.5 million in 2006. During 2007, we had $3.7 million in capital expenditures and net purchases of $1.4 million in marketable securities. The acquisition of our remaining 20% minority ownership interest resulted in a cash payment of
$30.3 million, of which $1.3 million was attributable to the minority interest and approximately $29.0 million was recorded as additional purchase price. Also, additional contingent consideration and other payments of approximately $5.1 million
relating to prior business acquisitions were paid during 2007. The current period also reflects $1.0 million of cash provided upon the repayment of a note receivable as well as $1.0 million resulting from the lifting of restrictions on certain cash
deposits. Net cash used in investing activities for the year ended December 31, 2006 consisted primarily of $5.7 million in capital expenditures (net of proceeds from sales of property and equipment of $1.0 million), net purchases of $14.5
million in marketable securities, and payments of $16.3 million, net of cash acquired, for business acquisitions, of which $15.9 million was used to acquire R/xx.

Net Cash Provided by Financing Activities.Net cash provided by financing activities for the year
ended December 31, 2008 was $15.7 million compared to $15.3 million in 2007. In 2008, we purchased $1.8 million of treasury stock, received proceeds of $4.6 million from the exercise of options and $0.4 million in proceeds from issuance of
common stock pursuant to the Employee Stock Purchase Plan. In addition, we received an income tax payable benefit of $5.5 million from the exercise of stock options and restricted stock vesting, and cash of $7.0 million related to the formation of
First Rx Specialty and Mail Services, LLC.

Net cash provided by financing activities for the year ended December 31, 2007 was $15.3
million compared to $5.7 million in 2006. In 2007, we purchased $1.4 million of treasury stock, received proceeds of $7.1 million from the exercise of options and $0.5 million in proceeds from issuance of common stock pursuant to the Employee Stock
Purchase Plan. In addition, we received an income tax payable benefit of $9.1 million from the exercise of stock options and restricted stock vesting. In 2006, we repaid $12.5 million in notes payable and received proceeds of $8.8 million from the
exercise of options and Employee Stock Purchase Plan purchases. In addition, we received an income tax payable benefit of $10.5 million from the exercise of stock options and restricted stock awards and incurred $1.1 million from all other financing
activities.

We anticipate continuing to generate positive operating cash flow which, combined with available cash resources, should be
sufficient to meet our planned working capital, capital expenditures and operating expenses for

the next year. However, there can be no assurance that we will not require additional capital. Even if such funds are not required, we may seek additional
equity or debt financing. We cannot be assured that such financing will be available on acceptable terms, if at all, or that such financing will not be dilutive to our stockholders.

|(1)    In December 2008, we formed an entity called First Rx Specialty and Mail Services, LLC and extended existing contracts with Walgreen Co. to provide certain mail and specialty pharmacy
services. As a part of this arrangement, we received $7.0 million in cash. We are also recognizing expense associated with the accretion of $1.0 million in other value. We have a contractual obligation to redeem the total investment in cash in the
year 2013. (2)    Total contractual obligations exclude the potential future payments required
in connection with possible contingent consideration associated with our HopsiScript acquisition. See Note 11 of the consolidated financial statements for a further discussion.

At December 31, 2008, we had available a $50.0 million revolving credit facility with no
outstanding borrowings.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Critical Accounting Policies and Estimates

Managements Discussion and Analysis of the
Financial Condition and Results of Operations discusses our consolidated financial statements. Preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates
and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Our estimates and assumptions are based upon a combination of historical information and various other assumptions believed to be
reasonable under the particular circumstances. Actual results could differ from those estimates. Certain of the accounting policies which most impact our consolidated financial statements and that require management to make difficult, subjective or
complex judgments are described below. See also Note 2, Summary of Significant Accounting Policies, to our consolidated financial statements included in Part II, Item 8 of this Annual Report on Form 10-K.

Revenue and direct expense recognition

We
recognize revenues from services provided to our clients for sales of prescription drugs either by pharmacies in our nationwide network or through our mail order facilities, and related claims processing fees. Revenue is recognized when the claims
are adjudicated. Pharmacy claims are adjudicated at the point-of-sale using an on-line claims processing system. When we have a contractual obligation to pay a network pharmacy provider for benefits provided to our clients members, total
payments from these clients are recorded as revenue and payments to the network pharmacy provider and the claim adjudication service costs are recorded as direct expenses. Generally, these contracts require us to assume the credit risk of our
clients abilities to pay. In addition, under the vast majority of our client contracts, we are at risk for the difference between the payments we receive from our clients and the negotiated reimbursements we pay to the pharmacies. When we
administer pharmacy reimbursement contracts and do not assume credit risk, we record only the net revenue and the administrative or processing fees. Rebates earned under arrangements with manufacturers are recorded as a reduction to direct expenses.
The portion of such rebates due to our clients is recorded as a reduction of revenue. Manufacturers rebates are based on estimates, which are subject to final settlement with the contracted party.

Member co-payments are not recorded as revenue. Under our client contracts, the pharmacy is solely obligated to collect the co-payments from the members.
Under client contracts, we do not assume liability for member co-payments in pharmacy transactions. As such, we do not include member co-payments to pharmacies in revenue or direct expenses.

Rebates Receivable and Payable

Rebates earned under arrangements with manufacturers are recorded as a reduction of direct expenses. The portion of such rebates due to clients is
recorded as a reduction of revenue. Manufacturer rebates are based on estimates, which are subject to final settlement with the contracted party on an annual basis. A contractual allowance for manufacturer rebates is established and adjusted
quarterly, if applicable, based on contractual terms with each manufacturer. The contractual allowance is included in our allowance for accounts receivable.

Allowance for Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear
interest. The allowance for accounts receivable is our best estimate of the amount of probable credit losses in our existing accounts receivable. We determine the allowance based on historical write-off experience by industry and regional economic
data. We review our allowance for accounts receivable monthly. All past due balances over 120 days are fully reserved. All other balances are reviewed on a pooled basis by type of receivable. Account balances are charged off against the allowance
when we feel it is probable the receivable will not be recovered. We do not have any off-balance-sheet credit exposure related to our customers.

Assets Acquired and Liabilities Assumed in Business Combinations

In our acquisitions, we are required to make
judgments regarding the fair values of the assets acquired and the liabilities assumed. For significant acquisitions, management has engaged independent consultants to assist it in estimating the fair values of acquired intangible assets.

Intangible Assets

We account
for our intangible assets under Statement of Financial Accounting Standards (SFAS) No. 142, Goodwill and Other Intangible Assets. Under SFAS No. 142, we do not have any intangible assets with indefinite lives. We do have
other intangible assets subject to amortization and these assets are amortized over 5 months to 20 years, depending on each intangible assets estimated useful life.

The estimated fair value and the weighted average useful-life of the intangible assets are based on income-method valuation calculations. The remaining useful life of intangible assets is evaluated periodically and
adjusted as necessary to match the period that the assets are expected to provide economic benefits.

Goodwill

We account for our goodwill under SFAS No. 142. Under SFAS No. 142, goodwill is not amortized, but it is tested for impairment at least
annually. Each year, we test for impairment of goodwill according to a two-step approach. In the first step, we test for impairment of goodwill by estimating the fair values of our reporting units using a present value of future cash flows approach,
subject to a comparison to market capitalization at the date of valuation. Although we operate in one reportable segment, for the purposes of performing this impairment test under FAS 142, we have identified three reporting units. If the carrying
amount of the reporting unit exceeds the fair value, the second step of the goodwill impairment test is performed to measure the amount of the impairment loss, if any. In the second step the implied fair value of the goodwill is estimated as the
fair value of the reporting unit used in the first step less the fair values of all other net tangible and intangible assets of the reporting unit. If the carrying amount of the goodwill exceeds its implied fair market value, an impairment loss is
recognized in an amount equal to that excess, not to exceed the carrying amount of the goodwill. In addition, goodwill of a reporting unit is tested for impairment between annual tests if an event occurs or circumstances change that would more
likely than not reduce the fair value of a reporting unit below its carrying value.

We account for contingent consideration according to
EITF 95-8, Accounting for Contingent Consideration Paid to the Shareholders of an Acquired Enterprise in a Purchase Business Combination, to determine whether contingent consideration should be accounted for as an adjustment to the purchase
accounting.

Investments

We have approximately $12.7 million at par value in investments related to auction rate securities (ARS), all of which are classified as non-current at December 31, 2008. For each of our ARS, we evaluate the
risks related to the structure, collateral and liquidity and estimate the fair value of the securities using a discount model based on (a) the underlying structure of each security; (b) the present value of future principal and interest
payments discounted at rates considered to reflect current market conditions; and (c) considerations of the probabilities of redemption or auction success for each period. Based on the results of these assessments, we record either a temporary
impairment charge, net of tax, in accumulated other comprehensive income or an other-than-temporary impairment charge in other income in our statement of operations. Accordingly, because we have the intent and ability to hold these securities until
liquidity returns to the market, other secondary markets develop, or the securities mature, we recorded a temporary impairment charge of $1.1 million in the fourth quarter of 2008 to reduce the value of our ARS classified as available-for-sale
securities. If circumstances arise which would require us to change our assumptions or the credit rating of the security issuer deteriorates, we may be required to adjust the carrying values of our available-for-sale ARS through an
other-than-temporary impairment charge in current period earnings.

Income Taxes

We account for income taxes in accordance with Statement of Financial Accounting Standard No. 109, Accounting for Income Taxes, (SFAS
No. 109), as clarified by FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (FIN 48). Under this method, deferred income taxes are determined based on the estimated future tax effects of
differences between the financial statement and tax bases of assets and liabilities given the provisions of enacted tax laws. Deferred income tax provisions and benefits are based on changes to the assets or liabilities from year to year. In
providing for deferred taxes, we consider tax regulations of the jurisdictions in which we operate, estimates of future taxable income, and available tax planning strategies. If tax regulations, operating results or the ability to implement
tax-planning strategies vary, adjustments to the carrying value of deferred tax assets and liabilities may be required. Valuation allowances, if any, are recorded related to deferred tax assets based on the more likely than not criteria
of SFAS No. 109.

FIN 48 requires that we recognize the financial statement benefit of a tax position only after determining that
the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater
than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority.

We may from time to time be
assessed interest or penalties by major tax jurisdictions, although any such assessments historically have been minimal and immaterial to our financial results. Our policy is that we recognize interest and penalties accrued on any unrecognized tax
benefits as a component of income tax expense.

RECENT ACCOUNTING PRONOUNCEMENTS

In April 2008, the FASB issued FASB Staff Position (FSP) FAS 142-3, Determination of the Useful Life of Intangible Assets. FSP FAS 142-3 amends
the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset under FASB Statement No. 142, Goodwill and Other Intangibles. FSP FAS 142-3 is
effective for fiscal years beginning after December 15, 2008 and early adoption is prohibited. The guidance for determining the useful life of a recognized intangible asset must be applied prospectively to intangible assets acquired after the
effective date. The disclosure requirements must be applied prospectively to all intangible assets recognized as of, and subsequent to, the effective date. We do not expect the adoption of FSP FAS 142-3 will have a material impact on our financial
position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), Business
Combinations (SFAS No. 141 (R)). SFAS No. 141(R) establishes principles and requirements for how an acquirer in a business combination recognizes and measures in its financial statements the identifiable assets
acquired, the liabilities assumed and any controlling interest in the acquiree at the acquisition date fair value. SFAS No. 141(R) will significantly change the accounting for business combinations in a number of areas including the treatment
of contingent consideration, pre-acquisition contingencies and transaction costs. In addition, any changes in an acquired entitys deferred tax assets and uncertain tax positions after the measurement period will impact income tax expense. SFAS
No. 141(R) also

includes a substantial number of new disclosure requirements. SFAS No. 141(R) is effective for fiscal years beginning after December 15, 2008 with
early application prohibited. We will adopt SFAS No. 141(R) beginning in the first quarter of fiscal 2009 and will change our accounting treatment for business combinations on a prospective basis.

INTEREST RATE AND FOREIGN EXCHANGE RISK

We are subject to interest rate risk on our investments. We do not expect our financial position, results of operations or cash flows to be affected to any significant degree by a sudden change in market interest rates.

We operate our business within the United States and Puerto Rico and execute all transactions in U.S. dollars and, therefore, we have no foreign exchange
risk.



|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

We have minimal market risk inherent in our financial position. We do not have any derivative financial instruments and do not hold any derivative financial instruments for trading purposes. Our market risk primarily represents the
potential loss arising from adverse changes in market interest rates. Our results from operations could be impacted by decreases in interest rates on our cash and cash equivalents, including our investments in auction rate securities. Additionally,
we may be exposed to market risk from changes in interest rates related to any debt that may be outstanding under our credit facility. We do not expect our cash flows to be affected to any significant degree by a sudden change in market interest
rates.

Managements Responsibility for
Financial Statements

Our management is responsible for the integrity and objectivity of all information presented in this annual
report. The consolidated financial statements were prepared in conformity with accounting principles generally accepted in the United States of America and include amounts based on managements best estimates and judgments. Management believes
the consolidated financial statements fairly reflect the form and substance of transactions and that the financial statements present fairly, in all material respects, our financial position, results of operations and cash flows.

The Audit Committee of the Board of Directors, which is composed solely of independent directors, meets regularly with the independent auditors and
representatives of management to review accounting, financial reporting, internal control and audit matters, as well as the nature and extent of the audit effort. The Audit Committee is responsible for the engagement of the independent auditors. The
independent auditors have free access to the Audit Committee.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and
operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of the end of the period covered by this Annual Report on Form 10-K. Based on this evaluation,
our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures are effective and designed to ensure that the information required to be disclosed in our reports filed or submitted under the
Exchange Act is recorded, processed, summarized and reported within the requisite time periods.

Managements Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules
13a-15(f) and 15d-15(f) under the Securities and Exchange Act of 1934. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of published
financial statements in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control
over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can only provide reasonable assurance with respect to financial statement preparation and presentation. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, assessed the effectiveness of our internal control
over financial reporting as of December 31, 2008. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal ControlIntegrated
Framework. Based on its assessment, management has concluded that as of December 31, 2008, our internal control over financial reporting was effective based on those criteria.

Our management has excluded Immediate Pharmaceutical Services, Inc. (IPS) from its assessment of internal controls over financial reporting as of
December 31, 2008 because it was acquired by us in a purchase business combination during 2008. IPS total assets and total revenues represent 8.1% and 1.4%, respectively, of the related consolidated financial statement amounts as of and
for the year ended December 31, 2008.

Our assessment of the effectiveness of our internal control over financial reporting as of
December 31, 2008 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears herein.

Changes in Internal Control Over Financial Reporting

No change in our internal control over
financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities and Exchange Act) occurred during the quarter ended December 31, 2008 that has materially affected, or is reasonable likely to materially affect, our internal
control over financial reporting.

Report of Independent Registered Public Accounting Firm

To Board of Directors and Stockholders of Catalyst Health Solutions, Inc.:

In our opinion, the accompanying consolidated financial statements listed in the index appearing under Item 15(a)(1) present fairly, in all material respects, the financial position of Catalyst Health Solutions, Inc. and its
subsidiaries at December 31, 2008 and 2007, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2008 in conformity with accounting principles generally accepted in the
United States of America. In addition, in our opinion, the financial statement schedule listed in Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated
financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2008, based on criteria established in Internal ControlIntegrated
Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Companys management is responsible for these financial statements, for maintaining effective internal control over financial reporting and
for its assessment of the effectiveness of internal control over financial reporting, included in Managements Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these
financial statements, on the financial statement schedule and on the Companys internal control over financial reporting based on our integrated 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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over
financial reporting was maintained in all material respects. Our audits of the financial statements included 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. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting,
assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered
necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A companys internal control over financial
reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A
companys internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures
of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of
the companys assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over
financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of
compliance with the policies or procedures may deteriorate.

As described in Managements Report on Internal Control over Financial Reporting,
management has excluded Immediate Pharmaceutical Services, Inc. (IPS) from its assessment of internal controls over financial reporting as of December 31, 2008 because it was acquired by the Company in a purchase business combination during
2008. We have also excluded IPS from our audit of internal control over financial reporting. IPS total assets and total revenues represent 8.1% and 1.4%, respectively, of the related consolidated financial statement amounts as of and for the year
ended December 31, 2008.

|2. | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
|-- | ------------------------------------------

Principles of
consolidation

The accompanying consolidated financial statements include the accounts of the Company and all of our subsidiaries. All
intercompany accounts and transactions have been eliminated.

Use of estimates

Preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to
make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. The most significant estimates included in these financial statements
include accounting for: rebates due from pharmaceutical manufacturing companies, the value of intangible assets acquired in business combinations and related amortization periods, impairment assessments of goodwill and allowance for accounts
receivable.

Fair value of financial instruments

At December 31, 2008 and 2007, our financial instruments included cash and cash equivalents, accounts receivable, investments, accounts payable and accrued liabilities. With the exception of our investments, the
fair values of these financial instruments approximated the carrying value due to the short-term maturities of these instruments. See Note 7 for a discussion of fair value of our investments.

Cash and cash equivalents

All highly liquid
investments purchased with an original maturity date of three months or less when purchased are classified as cash equivalents. The Company maintains its cash and cash equivalents in financial institutions with high credit ratings; however, at times
the balances may exceed federally insured amounts. The Company has not experienced any losses related to its cash or cash equivalents and believes it is not exposed to any significant credit risk on its cash or cash equivalents.

Short-term and long-term investments

The
Companys investments, which consist of auction rate securities (ARS), and are classified as available-for-sale and are recorded at fair market value, with unrealized gains (losses), net of taxes, reported as a separate component of
shareholders equity. At December 31, 2008, there was approximately $0.7 million, net of income tax of $0.4 million, in unrealized losses on investments included in accumulated other comprehensive income. Realized gains (losses) and
declines in market value judged to be other-than-temporary, of which there were none in 2008 and 2007, are included in other income.

Our
auction rate securities are floating rate securities with longer-term maturities with auction reset dates from 7 to 35 day intervals. Currently, certain of these securities have redemption features which call for redemption at 100% of par value and
are either partially federally guaranteed or required to maintain an asset coverage amount of

at least 200% in accordance with the Investment Company Act of 1940. Beginning in February 2008, auctions for these securities began to fail. Currently, we
are unlikely to be able to access these funds until future auctions for these securities are successful, or until we sell the securities in a secondary market which presently is not fully active, although there have been instances of redemptions at
par by issuers. As such, these investments currently lack short-term liquidity and therefore are classified as non-current on our December 31, 2008 balance sheet.

For each of our ARS, we evaluate the risks related to the structure, collateral and liquidity and estimate the fair value of the securities using a discount model based on (a) the underlying structure of each
security; (b) the present value of future principal and interest payments discounted at rates considered to reflect current market conditions; and (c) considerations of the probabilities of redemption or auction success for each period.
Based on the results of these assessments, we record either a temporary impairment charge, net of tax, in accumulated other comprehensive income or an other-than-temporary impairment charge in other income in our statement of operations. If
circumstances arise which would require us to change our assumptions or the credit rating of the security issuer deteriorates, we may be required to adjust the carrying values of our available-for-sale ARS through an other-than-temporary impairment
charge in current period earnings.

Accounts receivable

Based on the Companys direct expense recognition policies discussed below, certain rebates are estimated and unbilled at the end of the period. Receivables for rebates are calculated monthly based on an estimate
of rebatable prescriptions and the rebate per prescription. These estimates are adjusted to actual on a quarterly basis when the number of rebatable prescriptions and the rebate per prescription have been determined and the manufacturers are billed
for the rebates.

The allowance for accounts receivable is determined based on historical write-off experience. Account balances are
charged off against the allowance when the Company determines it is more than likely that the receivable will not be recovered. The Company does not have any off-balance-sheet credit exposure related to our clients.

Concentration of credit risk

Accounts receivable
consists principally of amounts due from the Companys PBM customers. In 2008, the Companys top ten clients generated approximately 64% of our consolidated revenue, including two customers who accounted for 18% and 12% of our consolidated
revenue. In 2007, the Companys top ten clients generated approximately 58% of consolidated revenue, including one customer which accounted for 20% of our consolidated revenue. In 2006, the Companys top ten clients generated
approximately 53% of our consolidated revenue, including two customers who accounted for 14% and 12% of our consolidated revenue. The Company holds no collateral for accounts receivable. Concentration of risks with respect to receivables is
mitigated based on the geographical dispersion of clients, the Companys communications with clients, and the Companys continuous review of outstanding receivables. Management also performs ongoing credit evaluations of its clients and
provides allowances as deemed necessary. The Company has not experienced significant losses related to receivables in the past. The Companys collection experience indicates limited loss exposure due to the nature of the benefits involved and
the necessity of benefit continuity for plan sponsor employees.

Inventory

Inventory consists of prescription drugs and medical supplies that are stated at the lower of weighted average cost or market.

Property and equipment

Property and equipment is
stated at cost and depreciated over their estimated useful lives using the straight-line method. The estimated useful lives range from 3-5 years for the Companys equipment and computer software while leasehold improvements are amortized over
the shorter of the estimated lives of the assets or the lease term.

Internally developed software

The Company capitalizes costs associated with software developed or obtained for internal use in accordance with American Institute of Certified Public Accountants Statement of Position 98-1, Accounting for the
Costs of Computer Software Developed or Obtained for Internal Use. Capitalized internal use software development costs include only (1) external direct costs of materials and services consumed in developing and obtaining software,
(2) payroll and payroll-related costs for employees who are directly associated with and who devote time to the project, and (3) interest costs incurred, when material, while developing the software. Capitalization of these costs ceases
when the project is substantially complete and ready for its intended purpose. Internally developed software is reported in the property and equipment line on the consolidated balance sheet.

Impairment of long-lived assets

The Company
investigates potential impairments of its long-lived assets when evidence exists that events or changes in circumstances may have made recovery of an assets carrying value unlikely. Under Statement of Financial Accounting Standard
(SFAS) No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, long-lived assets are considered to be potentially impaired when the sum of the expected undiscounted future net cash flows is less than the
carrying amount of the asset. Any related impairment loss is calculated based upon comparison of the fair value to the carrying value of the asset. No such impairment existed as of December 31, 2008 and 2007.

Intangible Assets

The Company accounts for its
intangible assets under SFAS No. 142, Goodwill and Other Intangible Assets. Under SFAS No. 142, the Companys other intangible assets with indefinite lives are not amortized, but are tested for impairment annually. Currently,
the Company does not have any intangible assets with indefinite lives.

The Company does have other intangible assets subject to
amortization and these assets are amortized over 5 months to 20 years, depending on each intangible assets estimated useful life. The estimated fair value and the weighted average useful-life of the intangible assets are based on income-method
valuation calculations. The remaining useful life of intangible assets is evaluated periodically by the Company and adjusted as necessary to match the period that the assets are expected to provide economic benefits. The Company concluded that no
impairment of intangible assets existed at December 31, 2008 and 2007.

Goodwill

The Company accounts for its goodwill under SFAS No. 142. Under SFAS No. 142, goodwill is not amortized, but it is tested for impairment at
least annually. Each year, the Company tests for impairment of goodwill as of December 31 according to a two-step approach. In the first step, we test for impairment of goodwill by estimating the fair values of our reporting units using a
present value of future cash flows approach, subject to a comparison to market capitalization at the date of valuation. Although we operate in one reportable segment, for the purposes of performing this impairment test under FAS 142, we have
identified three reporting units. If the carrying amount of the reporting unit exceeds the fair value, the second step of the goodwill impairment test is performed to measure the amount of the impairment loss, if any. In the second step, the implied
fair value of the goodwill is estimated as the fair value of the reporting unit used in the first step less the fair values of all other net tangible and intangible assets of the reporting unit. If the carrying amount of the goodwill exceeds its
implied fair market value, an impairment loss is recognized in an amount equal to that excess, not to exceed the carrying amount of the goodwill. In addition, goodwill of a reporting unit is tested for impairment between annual tests if an event
occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value.

The
Company accounts for contingent consideration according to EITF 95-8, Accounting for Contingent Consideration Paid to the Shareholders of an Acquired Enterprise in a Purchase Business Combination, to determine whether contingent consideration
should be accounted for as an adjustment to the purchase accounting or expensed as incurred.

Revenue and direct expense recognition

The Company recognizes revenue from services provided to its clients for sales of prescription drugs by either pharmacies in the Companys nationwide
network or through the Companys mail order facilities, and related claims processing fees. Revenue is recognized when the claims are adjudicated. Pharmacy claims are adjudicated at the point-of-sale using an on-line claims processing system.
When the Company has a contractual obligation to pay its network pharmacy providers for benefits provided to its clients members, total payments from these clients are recorded as revenue and payments to the network pharmacy provider and the
claim adjudication service costs are recorded as direct expenses. Generally, these contracts require the Company to assume the credit risk of its clients abilities to pay. In addition, under a vast majority of its client contracts, the Company
is at risk for the difference between the payments the Company receives from its clients and the negotiated reimbursements the Company pays to its pharmacies. When the Company administers pharmacy reimbursement contracts and does not assume credit
risk, the Company records only the net revenue and the administrative or processing fees.

Rebates earned under arrangements with drug
manufacturers are a reduction of direct expenses. The portion of such rebates due to clients is a reduction of revenue. Manufacturers rebates are based on estimates, which are subject to final settlement with the contracted party. A
contractual allowance for manufacturer rebates is established and adjusted quarterly, if applicable, based on contractual terms with each manufacturer.

Member co-payments are not recorded as revenue. Under the Companys pharmacy network contracts, the pharmacy is solely obligated to collect the co-payments from the members. Under client contracts, the Company
does not assume liability for member co-payments in pharmacy transactions. As such, the Company does not include member co-payments to pharmacies in revenue or direct expenses.

Income taxes

Deferred tax assets and liabilities are recognized for the expected future tax
consequences of events that have been included in the financial statements or tax returns. Deferred income taxes reflect the net effects of timing differences between the carrying amounts of assets and liabilities for financial reporting purposes
and the amounts used for income tax purposes measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

Net income per share

Basic net income per common share excludes dilution and is computed by dividing net income available
to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net income per common share reflects the potential dilution that could occur (using the treasury stock method) if options, restricted stock
awards, and warrants to issue common stock were exercised.

The following represents a reconciliation of the number of shares used in the
basic and diluted net income per share computations (amounts in thousands except per share data):

Other comprehensive income

Comprehensive income at December 31, 2008 consists of net income plus unrealized net losses on investments held as available for sale.

Stock-based compensation

On January 1, 2006, the Company adopted the provisions of SFAS
No. 123(R),Share-Based Payment, using the modified-prospective-transition method. Under the modified-prospective-transition method, compensation cost recognized in the year ended December 31, 2006 included (i) compensation
cost for all share-based payments granted prior to but not yet vested as of January 1, 2006, based on the grant date fair value estimated in accordance with the original provisions of SFAS No. 123, and (ii) compensation cost for all
share-based payments granted subsequent to January 1, 2006, based on the grant date fair value estimated in accordance with the provisions of SFAS No. 123(R).



|3. | RECENT ACCOUNTING PRONOUNCEMENTS
|-- | --------------------------------

In April 2008,
the FASB issued FASB Staff Position (FSP) FAS 142-3, Determination of the Useful Life of Intangible Assets. FSP FAS 142-3 amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful
life of a recognized intangible asset under FASB Statement No. 142, Goodwill and Other Intangibles. FSP FAS 142-3 is effective for fiscal years beginning after December 15, 2008 and early adoption is prohibited. The guidance for
determining the useful life of a recognized intangible asset must be applied prospectively to intangible assets acquired after the effective date. The disclosure requirements must be applied prospectively to all intangible assets recognized as of,
and subsequent to, the effective date. We do not expect the adoption of FSP FAS 142-3 will have a material impact on our financial position, results of operations or cash flows.

In December 2007, the FASB issued SFAS No. 141 (revised 2007), Business Combinations (SFAS No. 141 (R)). SFAS
No. 141(R) establishes principles and requirements for how an acquirer in a business combination recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed and any controlling interest in the
acquiree at the acquisition date fair value. SFAS No. 141(R) will significantly change the accounting for business combinations in a number of areas including the treatment of contingent consideration, pre-acquisition contingencies and
transaction costs. In addition, any changes in an acquired entitys deferred tax assets and uncertain tax positions after the measurement period will impact income tax expense. SFAS No. 141(R) also includes a substantial number of new
disclosure requirements. SFAS No. 141(R) is effective for fiscal years beginning after December 15, 2008 with early application prohibited. We will adopt SFAS No. 141(R) beginning in the first quarter of fiscal 2009 and will change
our accounting treatment for business combinations on a prospective basis.

Customer relationships represent the estimated fair value of the customer relationships at the
dates of acquisition. This estimated fair value and the weighted average useful-lives are based on incomemethod valuation calculations. Other PBM contracts allow us to provide PBM services, which are amortized over the future cash flow, based
on managements best estimate. During 2008, we wrote-off approximately $2.0 million of fully amortized intangible assets. There was no income statement impact for this adjustment.

Amortization expense of intangible assets for the years ended December 31, 2008, 2007 and 2006 was $5.3 million, $4.3 million and $3.0 million,
respectively. The estimated aggregate amortization expense of intangible assets for the years ending December 31, 2009, 2010, 2011, 2012 and 2013, is $5.7 million, $5.2 million, $4.7 million, $4.1 million and $4.1 million, respectively.

Goodwill represents the excess of the purchase price over the fair value of the net assets of
acquired businesses. The Company performed its annual impairment testing at December 31, 2008 and 2007 and concluded that no impairment of goodwill exists at its reporting units. Approximately $118.8 million and $39.4 million of the
Companys goodwill is deductible for income tax purposes in 2008 and 2007, respectively.



|7. | FAIR VALUE MEASUREMENTS
|-- | -----------------------

In September 2006, the
FASB issued SFAS No. 157, Fair Value Measurements (SFAS 157). SFAS No. 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. SFAS No. 157 is
effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. In February 2008, the FASB approved a Financial Staff Position that deferred the effective date of SFAS
No. 157 by one year for certain nonfinancial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis.

As of January 1, 2008, we adopted SFAS No. 157, with the exception of the application of
the statement to nonrecurring nonfinancial assets and nonfinancial liabilities. Nonrecurring nonfinancial assets and liabilities for which we have not applied the provisions of SFAS No. 157 include those measured at fair value in goodwill
impairment testing, indefinite lived intangible assets measured at fair value for impairment testing, and those initially measured at fair value in a business combination. Our limited adoption of SFAS No. 157, as amended, did not have a
material impact on our financial condition, results of operations or cash flows. Our evaluation of this standard is ongoing, and we have not yet determined the impact of the deferred portion of this standard on our financial condition, results of
operations or cash flows.

On January 1, 2008, we adopted SFAS No. 159, The Fair Value Option for Financial Assets and
Financial Liabilities (SFAS No. 159). We have not elected to use fair value measurements on any assets or liabilities under SFAS 159.

On October 10, 2008, the FASB issued FSP No. 157-3, Determining the Fair Value of a Financial Asset When the Market for That Asset is Not Active. FSP No. 157-3 clarifies the application of FAS
157 in a market that is not active and provides factors to take into consideration when determining the fair value of an asset in an inactive market. FSP No. 157-3 was effective upon issuance, including prior periods for which financial
statements have not been issued. This FSP did not have a material impact on our financial condition, results of operations or cash flows.

The following table details the fair value measurements within the fair value hierarchy of our financial assets (in thousands):

The valuation technique used to measure fair value for our Level 1 and 2 assets is a market
approach, with Level 1 using market prices and Level 2 using other relevant information generated by market transactions involving identical or comparable assets. The valuation technique used to measure fair value for our Level 3 assets is an income
approach, where the expected future cash flows were discounted back to present value for each asset.

In the second quarter of 2008, we
reclassified our investments related to auction rate securities (ARS) to the Level 3 category of the fair value hierarchy due to the continued lack of a market resulting in unobservable inputs associated with these securities. During the first
quarter of 2008, such investments, which are classified as non-current, were included in the Level 2 category. Our ARS are floating rate securities with longer-term maturities with auction reset dates from 7 to 35 day intervals. Beginning in
February 2008, auctions for these securities began to fail. Currently, we are unlikely to be able to access these funds until future auctions for these ARS are successful, or until we sell the securities in a secondary market which currently is not
fully active, although there have been instances of redemptions at par by issuers. As such, these investments currently lack short-term liquidity and therefore are classified as non-current on our December 31, 2008 balance sheet.

Due to the failed auction status and current lack of liquidity in the market for such securities, the valuation methodology includes certain assumptions
that were not supported by prices from observable current market transactions in the same instruments nor were they based on observable market data. For each of our ARS, we evaluate the risks related to the structure, collateral and liquidity and
estimate the fair value of the securities using a discount model based on (a) the underlying structure of each security; (b) the present value of future principal and interest payments discounted at rates considered to reflect current
market conditions; and (c) considerations of the probabilities of redemption or auction success for each period. Based on the results of these assessments, we record either a temporary impairment charge, net of tax, in accumulated other
comprehensive income or an other-than-temporary impairment charge in other income in our statement of operations. Accordingly, we recorded a temporary impairment charge of $1.1 million in the fourth quarter of 2008 to reduce the value of our ARS
classified as

available-for-sale securities. If circumstances arise which would require us to change our assumptions or the credit rating of the security issuer
deteriorates, we may be required to adjust the carrying values of our available-for-sale ARS through an other-than-temporary impairment charge in current period earnings.

Based on our cash and cash equivalents balance at December 31, 2008 of $55.0 million, our available $50.0 million revolving credit facility, and our positive operating cash flows, we do not anticipate a lack
of liquidity associated with our ARS to have a material impact on our liquidity, financial condition, results of operations or cash flows. We believe we have the ability to hold the securities until liquidity returns to the market, other secondary
markets develop, or the securities mature. Nonetheless, where appropriate, we are actively exploring and pursuing alternatives for obtaining relief from the unanticipated illiquidity of the ARS holdings, including seeking relief from entities
involved in investing our funds in ARS. As a part of these efforts, on February 23, 2009, we brought an arbitration claim before the Financial Industry Regulatory Authority (FINRA) against Credit Suisse Securities (USA), LLC
(Credit Suisse) seeking rescission, restitution and damages for Credit Suisses conduct in connection with our investment account with Credit Suisse.

|8. | CREDIT FACILITY AND NOTES PAYABLE
|-- | ---------------------------------

In September
2006, we entered into a new $50.0 million revolving credit facility with our primary commercial bank. The facility is for a three-year term expiring September 2009 and bears interest at LIBOR plus a variable margin based on our ratio of funded debt
to earnings before interest, taxes, depreciation and amortization expense (EBITDA), payable in arrears on the first day of each month. The credit facility is collateralized by all of our assets. The facility contains affirmative and
negative covenants including those related to indebtedness and EBITDA.

At December 31, 2008 and 2007, we had no net borrowings under
the credit facility. During the third quarter of 2008, there was a drawing under the credit facility of $25.0 million, which was subsequently repaid prior to year end. Interest expense in 2008 related to the drawings on this credit facility was
approximately $0.2 million.



|9. | INCOME TAXES
|-- | ------------

Effective January 1, 2007, the
Company adopted the provisions of FASBs Interpretation No. 48, Accounting for Uncertain Tax Positions (FIN 48). This interpretation clarifies the accounting for uncertain tax positions in accordance with FASB Statement
No. 109, Accounting for Income Taxes. The interpretation prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax
return. The interpretation also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. We have evaluated our tax positions in the tax returns filed, as well as un-filed
tax positions and the amounts comprising our deferred tax assets. We have determined that FIN 48 did not have a material impact on our financial condition, results of operations or cash flows.

The Company files income tax returns in the U.S. federal jurisdiction and various state jurisdictions. Our federal income tax returns for 2005 through
2008 are open tax years. State jurisdictions that remain subject to examinations range from 2004 to 2008.

The Company may from time to time be assessed interest or penalties by major tax jurisdictions,
although any such assessments historically have been minimal and immaterial to our financial results. Our policy is that we recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense.

The Company had net operating loss carryforwards of $4.9 million and $1.8 million at
December 31, 2008 and 2007, respectively, which were available to offset future state taxable income.

The Company had determined that
a valuation allowance is needed against a deferred tax asset related to the capital loss that the Company realized during 2008 because there is not enough positive evidence to meet the more likely than not threshold for recognition.

was $15.4 million and $23.2 million, respectively.

A summary of the Companys restricted share activity for the year ended December 31, 2008 is as follows (in thousands, except for fair market
value per share):

The fair value of restricted shares, based on the Companys stock price at the date of grant,
is expensed over the vesting period. As of December 31, 2008 and 2007, the total remaining unrecognized compensation cost related to non-vested restricted shares was approximately $9.9 million and $9.3 million, respectively, with a weighted
average period over which it is expected to be recognized of 2.5 years.

Employee Stock Purchase Plan

Prior to January 1, 2007, the Company offered an employee stock purchase plan (ESPP) that allowed eligible employees to purchase shares
of the Companys common stock each quarter at 85% of the market value on the first or last day of the quarter. The ESPP was considered compensatory under the provisions of SFAS No. 123(R) and for the year ended December 31, 2006, the
Company incurred $0.2 million in related stock-based compensation expense.

Effective January 1, 2007, the ESPP was modified, allowing
eligible employees to purchase shares of the Companys common stock each quarter at 95% of the market value on the last day of the quarter. The ESPP, as modified, is not considered compensatory under the provisions of SFAS No. 123(R) and
therefore no portion of the costs related to ESPP purchases are included in the Companys stock-based compensation expense for the years ended December 31, 2007 and 2008.

Common Stock Warrants

During 2002, the Company issued common stock warrants to a customer granting the right to purchase 250,000 shares of the Companys common stock for $5.22 per share. The warrants were exercisable at any time after
the grant date, with a condition that the Company must be the exclusive provider of PBM services to the customer on the date of exercise. The term of the PBM contract was from July 1, 2002, to September 30, 2009. Using an equity-pricing
model, the 250,000 warrants were valued at $400,000, a charge that was being recognized on a straight-line basis over the life of the seven-year contract beginning July 2002. The Company recorded $57,000 of contra-revenue related to amortization of
the cost of the warrants in each of 2008, 2007 and 2006, respectively. All 250,000 of these warrants were exercised in 2005.

Pursuant to
an acquisition in 2004, the Company issued common stock warrants of 55,000, 100,000 and 100,000, effective July 2007, 2006 and 2005, respectively, at an exercise price of $15.45 per share. The warrants were issued based on the achievement of certain
revenue and gross profit targets. The issuance of these warrants resulted in additional goodwill as a component of acquisition accounting. These 255,000 common stock warrants remain issued and outstanding at December 31, 2008.

Treasury Stock

Recipients of restricted stock awards
are provided the opportunity to sell a portion of those shares to the Company at the time the shares vest, in order to pay their withholding tax obligations. The Company accounts for these share purchases as treasury stock transactions using the
cost method. For the years ended December 31, 2008 and 2007, 70,000 and 52,000 shares, respectively, were used for this purpose at a value of approximately $1.8 million and $1.4 million, respectively.



|11. | BUSINESS COMBINATIONS
|--- | ---------------------

Acquisition of Immediate Pharmaceutical
Services, Inc.

On August 5, 2008, we acquired Immediate Pharmaceutical Services, Inc. (IPS) from Discount Drug Mart,
Inc. IPS operates a fully-integrated prescription mail service fulfillment center located outside of Cleveland, Ohio. The IPS acquisition provides us with a foundation for building our mail service capability and to enable us to provide our clients
with an in-house mail service option. Total consideration for the acquisition of IPS consisted of cash payments of $40.0 million and approximately $1.2 million in transaction costs. The purchase price of IPS was largely determined on the basis of
managements expectations of future earnings and cash flows, resulting in the recognition of goodwill. Based on managements best estimate, the acquisition of IPS resulted in $24.2 million of goodwill and $6.0 million of customer
relationship intangibles with an estimated useful life of 18 years. Goodwill related to this acquisition is non-deductible for tax purposes.

The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition. The acquisition was accounted for as a purchase, and accordingly, the results of IPS operations are included
in our consolidated financial statements since the date of acquisition. The allocation of the purchase price to the net assets acquired will be finalized upon managements completion of its valuation. Consequently, the allocation of purchase
price to intangible assets is subject to adjustment. Amounts are in thousands.

Acquisition of HospiScript Services, LLC

On May 16, 2008, we acquired HospiScript Services, LLC and Concept Pharmaceuticals, LLC, a related party to HospiScript Services through common
ownership (collectively, HospiScript). HospiScript provides pharmacy medication therapy management services to the hospice industry.

Total consideration for the acquisition of HospiScript consisted of cash payments of $102.7 million and $0.4 million in transaction related costs. Additionally, the acquisition provides for possible contingent consideration payments through
2010 of up to $8.1 million, subject to specified operating performance standards, of which approximately $0.9 million was earned in 2008. Contingent consideration earned is accounted for as additional goodwill.

The purchase price of HospiScript was largely determined on the basis of managements expectations of future earnings and cash flows, resulting in
the recognition of goodwill. Based on managements best estimate, including our valuation report of the allocation of the purchase price to the net assets acquired, the acquisition of HospiScript resulted in goodwill of $79.4 million and
intangibles assets, consisting of customer relationships of $18.6 million with an estimated 18 year life, trade names of $1.4 million with an estimated 3.5 year life, and developed technology of $0.6 million with an estimated 5 year life. Goodwill
related to this acquisition is deductible for tax purposes.

The following table summarizes the estimated fair values of the assets
acquired and liabilities assumed at the date of acquisition. The acquisition was accounted for as a purchase, and accordingly, the results of HospiScript operations are included in our consolidated financial statements since the date of acquisition.

Acquisition ofR/xx

In November 2006, the Company purchased all of the outstanding common stock of R/xxPharmacy Solutions, Inc.
(R/xx), an Arizona corporation, for $16.0 million in cash and $0.7 million in related transaction costs. Pursuant to the acquisition
agreement, additional cash consideration of $2.1 million was earned and paid in 2007 based on successful achievement of certain client retention criteria and recorded as additional goodwill. R/xxis a provider of pharmacy benefit management services with a strategic focus on clients in the Arizona, Nevada and Hawaii markets.

Acquisition of EBRx

In December 2005, the Company
acquired the common stock of EBRx. Consideration consisted of a cash payment of $27.9 million and $0.9 million in related transaction costs. Pursuant to the acquisition agreement, additional cash consideration of $2.9 million was earned and paid
through 2007 based on successful achievement of certain performance based standards and recorded as additional goodwill.

In January 2006,
as contemplated by the original transaction, a separate entity owned by former owners of EBRx and its management team purchased a 20% ownership interest in the parent of EBRx through a $1.0 million equity investment. In February 2007, under the
terms of the transaction, we acquired this remaining 20% minority ownership interest. This transaction resulted in a cash payment of $30.3 million, of which $29.0 million was recorded as additional goodwill, prior to the repayment of certain related
transaction debt and accrued interest. In May 2007, the related transaction debt of $1.0 million plus accrued interest of $0.1 million was repaid.

Other acquisitions

To support its geographic expansion and growth, the Company has periodically completed various
insignificant business acquisitions to secure local operating assets, new pharmacy network contracts and local market executive offices. None of these transactions has had any significant impact on the Companys reported revenues, assets or
results of operations.



|12. | LEASE COMMITMENTS
|--- | -----------------

The Company maintains
non-cancelable lease agreements for office space in its 22 main operating locations. These agreements provide for annual escalations and payment by the Company of its proportionate share of the increase in the costs of operating the buildings. The
Company also leases certain office equipment. The Company recognizes rent expense on a straight-line basis over the terms of the leases.

Rent expense for the years ended December 31, 2008, 2007 and 2006 was $5.1 million, $3.3
million and $2.4 million, respectively.



|13. | COMMITMENTS AND CONTINGENCIES
|--- | -----------------------------

In December 2008, we
formed an entity called First Rx Specialty and Mail Services, LLC and extended existing contracts with Walgreen Co. to provide certain mail and specialty pharmacy services. This initiative is designed to provide enhanced capabilities in the
distribution of specialty drugs, invest in various member-focused programs to deliver care-effective and cost-effective drugs to our customers, and access the Walgreens network of mail service pharmacies for over-flow mail volume, back-up, and
redundancy. As a part of this arrangement, we received $7.0 million in cash. We have considered the accounting for the investment and the contract extension and have recorded a liability in our consolidated balance sheet at December 31, 2008,
pursuant to Financial Accounting Standard No. 150, Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity. We are also recognizing expense associated with the accretion of $1.0 million in other
value to an ultimate redemption value of $8.0 million. We have a contractual obligation to redeem the total investment in cash in the year 2013.

In the ordinary course of our business, we are sometimes required to provide financial guarantees related to certain customer contracts. These financial guarantees may include performance bonds, standby letters of
credit or other performance guarantees. These financial guarantees represent obligations to make payments to customers if we fail to fulfill an obligation under a contractual arrangement with that customer. We have had no history of significant
claims, nor are we aware of circumstances that would require us to perform under these arrangements. We believe that the resolution of any claim that might arise in the future, either individually or in the aggregate, would not have a material
adverse effect on our financial condition, results of operations or cash flows.



|14. | SEGMENT REPORTING
|--- | -----------------

SFAS No. 131,
Disclosures about Segments of an Enterprise and Related Information, establishes standards for the way that public enterprises report information about operating segments in financial statements. We have determined that we operate in only one
segment  the pharmacy benefits management, or PBM, segment. Accordingly, no segment disclosures have been included in the notes to the consolidated financial statements.



|15. | 401(k) SAVINGS PLAN
|--- | -------------------

In April 2000, the Company
authorized the establishment of an employee 401(k) Savings Plan (the Plan). The Plan benefit is available to all Company employees, subject to certain service requirements. The Company matches the first $1,000 of the employees
contribution and 50% thereafter, up to a discretionary pre-defined limit, on the first ten percent of the employees pre-tax deferral subject to statutory limits. The Companys matching contribution vests ratably over 5 years for each
employee. For the years ended December 31, 2008, 2007, and 2006, the Company incurred expense of $0.8 million, $0.7 million, and $0.8 million respectively, under the Plan.



|16. | RELATED PARTY TRANSACTIONS
|--- | --------------------------

In February 2006, the
Company entered into a sublease with United Medical Bank, FSB (UMB) for 4,364 square feet of finished office space on the third floor of 800 King Farm Boulevard. A member of the Companys Board of Directors at that time (the
related party), held a controlling interest in UMB. The rental rate under the sublease was the same rate specified under UMBs prime lease with the landlord. The Company paid $115,000 in sublease payments in 2006 and $86,000 in
2007. The sublease was terminated effective August 31, 2007.

In September 2007, the Company expanded its corporate offices in Rockville, Maryland by acquiring
34,382 square feet of finished office space from two related party lessees on the third floor of 800 King Farm Boulevard. In these transactions the Company assumed one prime lease with the landlord for 17,487 square feet of space and agreed to
assume a second prime lease with the landlord for another 16,895 square feet. In the second transaction, the Company contemporaneously subleased 6,932 square feet of finished office space it held on the first floor of 800 King Farm Boulevard back to
the related party. The transactions allowed the Company to consolidate operations on two contiguous floors and reflected only the assumption of actual occupancy costs. The rent charged by the Company under the sublease is the Companys actual
rent obligation for the space amounting to $233,000 and $76,000 in 2008 and 2007, respectively.

In November 2008, the Company continued
its expansion of corporate offices in Rockville, Maryland by acquiring an additional 3,032 square feet of finished office space from a related party lessee on the third floor of 800 King Farm Boulevard. The Companys rent obligation for this
space amounted to approximately $8,000 in 2008.
