1.50% Cash Convertible Senior Notes Due 2018

On July 16, 2013, the Company completed a private placement of $150.0 million aggregate principal amount of cash convertible senior notes due 2018 (the "Cash Convertible Notes"), which bear interest at a rate of 1.50 % per year, payable semiannually in arrears on January 1 and July 1 of each year, beginning on January 1, 2014. The Cash Convertible Notes will mature on July 1, 2018, unless earlier repurchased or converted into cash in accordance with their terms prior to such date. The Cash Convertible Notes are convertible into cash based on the conversion rate set forth below and are not convertible into our common stock or any other securities under any circumstances. The initial cash conversion rate is 51.38 shares of our common stock per $1,000 principal amount of Cash Convertible Notes (equivalent to an initial conversion price of approximately $19.46 per share of common stock). The Cash Convertible Notes are our senior unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Cash Convertible Notes. As a result of this transaction, we recognized deferred loan costs of approximately $3.9 million, which are being amortized over the term of the Cash Convertible Notes using the effective interest method.

The cash conversion feature of the Cash Convertible Notes (the "Cash Conversion Derivative") requires bifurcation from the Cash Convertible Notes in accordance with ASC Topic 815, Derivatives and Hedging, and is recorded in other long-term liabilities as a derivative liability and carried at fair value. The fair value of the Cash Conversion Derivative at the time of issuance of the Cash Convertible Notes was $36.8 million, which was recorded as a debt discount for purposes of accounting for the debt component of the Cash Convertible Notes. The debt discount is being amortized over the term of the Cash Convertible Notes using the effective interest method. For the twelve months ended December 31, 2013, we recorded $3.1 million of interest expense related to the amortization of the debt discount based upon an effective interest rate of 5.7%. The net carrying amount of the Cash Convertible Notes at December 31, 2013 was $116.4 million, net of the unamortized discount of $33.6 million.

In connection with the issuance of the Cash Convertible Notes, we entered into privately negotiated convertible note hedge transactions (the "Cash Convertible Notes Hedges"), which are cash-settled and are intended to reduce our exposure to potential cash payments that we would be required to make if holders elected to convert the Cash Convertible Notes at a time when our stock price exceeded the conversion price. The initial cost of the Cash Convertible Notes Hedges was $36.8 million. The Cash Convertible Notes Hedges are recorded in other assets as a derivative asset under FASB ASC Topic 815 and are carried at fair value. See Note 8 for additional information regarding the Cash Convertible Notes Hedges and the Cash Conversion Derivative and their fair values as of December 31, 2013.

In July 2013, we also sold separate privately negotiated warrants (the "Warrants") initially relating, in the aggregate, to approximately 7.7 million shares of our common stock underlying the Cash Convertible Notes Hedges. The Warrants have an initial strike price of approximately $25.95 per share, which effectively increases the conversion price of the Cash Convertible Notes to a 60% premium to our stock price on July 1, 2013. The Warrants will be net share settled by issuing a number of shares of our common stock per Warrant corresponding to the excess of the market price per share of our common stock (as measured on each warrant exercise date under the terms of the Warrants) over the applicable strike price of the Warrants. The Warrants meet the definition of derivatives under the guidance in ASC Topic 815; however, because these instruments have been determined to be indexed to our own stock and meet the criteria for equity classification under ASC Topic 815-40, the Warrants have been accounted for as an adjustment to our additional paid-in-capital.

If the market value per share of our common stock exceeds the strike price of the warrants, the warrants will have a dilutive effect on net income per share, and the "treasury stock" method will be used in calculating the dilutive effect on earnings per share.

CareFirst Convertible Note

On October 1, 2013, we entered into an Investment Agreement (the "Investment Agreement") with CareFirst Holdings, LLC ("CareFirst"), which is in addition to certain existing commercial agreements between us and CareFirst relating to, among other things, disease management and care coordination services (the "Commercial Agreements"). Pursuant to the Investment Agreement, we issued to CareFirst a convertible subordinated promissory note in the aggregate original principal amount of $20 million (the "CareFirst Convertible Note") for a purchase price of $20 million. The CareFirst Convertible Note bears interest at a rate of 4.75% per year, payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each calendar year, beginning on December 31, 2013. The CareFirst Convertible Note may be prepaid only under limited circumstances and upon the terms and conditions specified therein. If the CareFirst Convertible Note has not been fully converted or redeemed in accordance with its terms, it will mature on October 1, 2019. The CareFirst Convertible Note is subordinate in right of payment to the prior payment in full of (a) all indebtedness of the Company under the Fifth Amended Credit Agreement, and (b) any other senior debt of the Company, which currently includes only the Cash Convertible Notes.

The CareFirst Convertible Note is convertible into shares of our common stock at the conversion rate determined by dividing (a) the sum of the portion of the principal to be converted and accrued and unpaid interest with respect to such principal by (b) the conversion price equal to $22.41 per share of our common stock. The conversion price is subject to adjustment for stock splits, stock dividends, recapitalizations, reorganizations, reclassifications and similar events.

CareFirst has an opportunity to earn warrants to purchase shares of our common stock ("CareFirst Warrants") based on achievement of certain quarterly thresholds (the "Revenue Thresholds") for revenue derived from both the Commercial Agreements and from new business to us from third parties as a result of an introduction or referral to us by CareFirst (collectively, the "Quarterly Revenue"). If the Quarterly Revenue is greater than or equal to the applicable Revenue Threshold for any quarter ending on or prior to September 30, 2017, then we will issue to CareFirst a certain number of warrants exercisable for the number of shares of our common stock ("CareFirst Warrant Shares") determined in accordance with the terms of the Investment Agreement unless (i) CareFirst elects to receive a cash payment in accordance with the terms of the Investment Agreement or (ii) there is a change of control. The aggregate number of CareFirst Warrant Shares in any single 12-month period beginning on October 1, 2013 cannot exceed 400,000, and the aggregate number of CareFirst Warrant Shares issuable pursuant to the Investment Agreement cannot exceed 1,600,000. If issued, the CareFirst Warrants will have a dilutive effect on net income per share, and the "treasury stock" method will be used in calculating the dilutive effect on earnings per share.

Also on October 1, 2013, in connection with the execution of the Investment Agreement, we entered into a Registration Rights Agreement with CareFirst, pursuant to which we agreed to use commercially reasonable efforts to cause any registration statement covering an underwritten offering of our common stock for our own account or for the account of any holder of our common stock (other than a registration statement on Form S-4 or Form S-8 or any successor thereto) to include those registrable common shares that any holder of such registrable common shares has requested to be registered.

The term of the Investment Agreement expires on the earlier of (a) December 31, 2017 and (b) the first date on which no Commercial Agreement is in effect.

Credit Facility

On June 8, 2012, we entered into the Fifth Amended Credit Agreement. The Fifth Amended Credit Agreement provides us with a $200.0 million revolving credit facility that expires on June 8, 2017 and includes a swingline sub facility of $20.0 million and a $75.0 million sub facility for letters of credit. The Fifth Amended Credit Agreement also provides a $200.0 million term loan facility that matures on June 8, 2017, $110.0 million of which remained outstanding at December 31, 2013, and an uncommitted incremental accordion facility of $200.0 million.

Borrowings under the Fifth Amended Credit Agreement generally bear interest at variable rates based on a margin or spread in excess of either (1) the one-month, two-month, three-month or six-month rate (or with the approval of affected lenders, nine-month or twelve-month rate) for Eurodollar deposits ("LIBOR") or (2) the greatest of (a) the SunTrust Bank prime lending rate, (b) the federal funds rate plus 0.50%, and (c) one-month LIBOR plus 1.00% (the "Base Rate"), as selected by the Company. The LIBOR margin varies between 1.75% and 3.00%, and the Base Rate margin varies between 0.75% and 2.00%, depending on our leverage ratio. The Fifth Amended Credit Agreement also provides for an annual fee ranging between 0.30% and 0.50% of the unused commitments under the revolving credit facility. Extensions of credit under the Fifth Amended Credit Agreement are secured by guarantees from all of the Company's active domestic subsidiaries and by security interests in substantially all of the Company's and such subsidiaries' assets.

On February 5, 2013, we entered into an amendment to the Fifth Amended Credit Agreement, which included, among other things, a temporary increase in the LIBOR and Base Rate margins of 0.25%. The increased margins were effective through December 31, 2013 and applied only when our total funded debt to EBITDA ratio was greater than or equal to 3.50 to 1.00. On July 1, 2013, we entered into an additional amendment to the Fifth Amended Credit Agreement, which provided for, among other things, the amendment of certain negative covenants to permit the issuance of and payments related to the Cash Convertible Notes described above as well as increases in the maximum required levels of total funded debt to EBITDA beginning with the quarter ended June 30, 2013. As of December 31, 2013, availability under the revolving credit facility totaled $38.7 million as calculated under the most restrictive covenant.

We are required to repay outstanding revolving loans under the revolving credit facility on June 8, 2017. We are required to repay term loans in quarterly principal installments aggregating (1) 1.250% of the original aggregate principal amount of the term loans during each of the eight quarters beginning with the quarter ended September 30, 2012, (2) 1.875% of the original aggregate principal amount of the term loans during each of the next four quarters beginning with the quarter ending September 30, 2014, and (3) 2.500% of the original aggregate principal amount of the term loans during each of the remaining quarters prior to maturity on June 8, 2017, at which time the entire unpaid principal balance of the term loans is due and payable.

The following table summarizes the minimum annual principal payments and repayments of the revolving advances under the Fifth Amended Credit Agreement, the Cash Convertible Notes, and the CareFirst Convertible Note for each of the next five years and thereafter:

(In thousands)
Year ending December 31,
2014	$	12,500
2015		17,500
2016		20,000
2017		63,625
2018		150,000
2019 and thereafter		20,000
Total	$	283,625

The Fifth Amended Credit Agreement contains financial covenants that require us to maintain specified ratios or levels of (1) total funded debt to EBITDA and (2) fixed charge coverage. As of December 31, 2013, we were in compliance with all of the financial covenant requirements of the Fifth Amended Credit Agreement.

The Fifth Amended Credit Agreement contains various other affirmative and negative covenants that are typical for financings of this type. Among other things, the Fifth Amended Credit Agreement limits repurchases of the Company's common stock and the amount of dividends that the Company can pay to holders of its common stock.
