Such payments were effective as of January 1, 2012 and will be pro-rated for partial months in which services were provided. Catalyst also agreed to reimburse Messrs. Civera and Jollon for all reasonable out-of-pocket expenses incurred by them in connection with their provision of services. In addition, Catalyst issued to each of Messrs. Civera and Jollon 10,000 shares of Catalyst restricted common stock under the 2006 Stock Incentive Plan. These shares of restricted stock will vest in full immediately prior to the consummation of a strategic transaction (as defined in the agreements with Mr. Civera and Jollon). If a strategic transaction does not occur on or prior to December 31, 2013, all such shares will immediately be forfeited. The merger constitutes a strategic transaction under Messrs. Civera’s and Jollon’s agreements and, immediately prior to the effective date of the merger, all such shares of restricted stock issued to Mr. Civera and Jollon will vest and, upon consummation of the merger, will be converted into the right to receive the merger consideration.”

2. On page 54 of the Joint Proxy Statement/Prospectus, insert the following at the end of the carryover paragraph on such page:

“During the course of their discussion, Mr. Blair informed Mr. Thierer that he would be willing to take on a role at the combined company for a period of time following closing to assist with integration.”

3. On page 89 of the Joint Proxy Statement/Prospectus, insert the following at the end of the fourth sentence:

“The following table presents the EV/LTM EBITDA calculated by Goldman Sachs with respect to each of the selected transactions:

Date Announced	Acquiror	Target	EV/LTM EBITDA

4. On page 91 of the Joint Proxy Statement/Prospectus, insert the following at the end of the first paragraph on such page under the heading “—Illustrative Discounted Cash Flow Analyses”:

“The unlevered free cash flow estimates used by Goldman Sachs for Catalyst and SXC for the last six months of 2012 and for 2013 through 2016 in its illustrative discounted cash flow analyses are set forth under “Financial Forecasts.” The estimates of terminal year unlevered free cash flows used by Goldman Sachs are described below.”

5. On page 91 of the Joint Proxy Statement/Prospectus, insert the following after the last paragraph on such page under the heading “—Illustrative Discounted Cash Flow Analyses”:

“Stock-based compensation was reflected as a cash expense in the estimates of unlevered free cash flows used for Catalyst (on a standalone-basis) and for the combined company for the last six months of 2012 and for 2013 through 2016 and for purposes of calculating estimates of terminal year unlevered free cash flows for Catalyst (on a standalone basis) and for the combined company, respectively. Stock-based compensation was not reflected as a cash expense in the estimates of unlevered free cash flows used for SXC (on a stand-alone basis) for the last six months of 2012 and for 2013 through 20161. Stock-based compensation was reflected as a cash expense in the estimate of stand alone terminal year unlevered free cash flows used for purposes of calculating terminal values for SXC (on a stand-alone basis).

Using management forecasts, Goldman Sachs calculated estimates of terminal year unlevered free cash flows for Catalyst and SXC on a stand-alone basis and for the combined company by taking estimates of 2016 after-tax EBIT (excluding synergies), adding back estimates of depreciation, and subtracting estimates of capital expenditures. However, no working capital changes, no cash flow for acquisitions, no integration expenses and no acquisition-related amortization expenses were reflected in the estimates of terminal year unlevered free cash flows used by Goldman Sachs. The estimates of terminal year unlevered free cash flows calculated by Goldman Sachs for Catalyst was $300 million and for SXC was $304 million.”

6. On page 112 of the Joint Proxy Statement/Prospectus, replace the last sentence in the second paragraph under the heading “—Interests of Catalyst’s Directors and Executive Officers in the Merger” with the following:

“As of June 1, 2012, the date of the joint proxy statement/prospectus, SXC and Mr. Blair had not negotiated the specifics of any such role or the terms and conditions, if any, relating to Mr. Blair’s involvement with the combined company following the completion of the proposed merger. Terms discussed prior to such date included Mr. Blair being available for consultation upon reasonable request for a period of six months following the closing, nominal compensation for Mr. Blair, the provision of office space and administrative assistance, and reimbursement of certain expenses. These terms had not been agreed to and were subject to change. Following, on June 4, 2012, Catalyst and Mr. Blair entered into an Independent Consultant Services Agreement relating to Mr. Blair’s involvement with the combined company following the completion of the proposed merger. Under the terms of this agreement, Mr. Blair will be available to the combined company for consultation upon reasonable request until December 31, 2013 and will receive nominal compensation of $1.00 per month. Mr. Blair will be provided with office space and administrative assistance, and will be reimbursed for certain of his expenses.”

1 Goldman Sachs has informed us that its use for purposes of its analysis of estimates of unlevered free cash flow for SXC that did not reflect stock-based compensation as a cash expense was erroneous. Goldman Sachs has informed Catalyst that the impact of this error was not material to Goldman Sachs’ analysis.

12. On page 178 of the Joint Proxy Statement/Prospectus, insert the following after footnote (1) in the first table thereon:

“Catalyst’s Extrapolation of SXC Unaudited Prospective Financial Information

In addition, Catalyst management also calculated and provided to Catalyst’s financial advisor certain prospective financial information for SXC for the years ending December 31, 2015 and 2016. This information was prepared by Catalyst management by extrapolating from the prior years’ projections provided by SXC described

above. In doing so, Catalyst made no adjustments to the components of the SXC projections provided by SXC to Catalyst management. These calculations were based on the following assumptions: (i) revenues for 2015 and 2016 were extrapolated using the 2014 revenue growth rate, (ii) gross profits for 2015 and 2016 were extrapolated from previous years by using the previous year’s gross margin plus an increase consistent with the margin growth trend in SXC’s 2012 through 2014 projections, (iii) development costs, depreciation and amortization for 2015 and 2016 were extrapolated as a percentage of revenue based on the 2014 percentage of revenue, and (iv) other selling, general and administrative expenses (“SG&A”) for 2015 and 2016 were extrapolated as a percentage of revenue by using the 2014 percentage of revenue plus a decrease consistent with the SG&A trend in SXC’s 2012 through 2014 projections. SXC and its financial advisors did not participate in, or in any way verify, and made no judgments about, the calculations comprising the extrapolated information prepared by Catalyst.

The following table presents summary selected SXC unaudited prospective financial information for the fiscal years ending 2015 through 2016 as extrapolated by Catalyst management using the SXC unaudited prospective financial information summarized under “—SXC Summary Unaudited Prospective Financial Information.”

13. On page 179 of the Joint Proxy Statement/Prospectus, insert the following immediately after the first full paragraph thereon:

“Stand-Alone SXC and Catalyst Projections Combined

In addition, Catalyst management combined the stand-alone projections for SXC for the years ending December 31, 2012 through 2014 and the extrapolations thereof prepared by Catalyst management for the years ending December 31, 2015 and 2016, with the stand-alone projections for Catalyst for the years ending December 31, 2012 through 2016 and took into account the synergies estimates developed by Catalyst management for the combined company for the years ending December 31, 2012 through 2016 (the “Combined Projections”). Catalyst’s management did not make any pro forma adjustments in combining the stand-alone projections of SXC or Catalyst other than taking into account the synergies that Catalyst management estimated the combined company would achieve. The Combined Projections are not the result of any planning processes, analysis or management input of either SXC or Catalyst and should not be taken by readers to represent anything other than the combination of the applicable line items from the stand-alone projections of SXC and Catalyst, after taking into account estimated synergies. In addition, no assurances can be made as to what level of synergies, if any, the combined company will achieve. SXC and its financial advisors did not participate in, or in any way verify, and made no judgments about, the Combined Projections (other than providing the SXC projections described above for the years ending December 31, 2012 through 2014 and participating in discussions with Catalyst management regarding potential synergies).

The following table presents summary selected combined company unaudited prospective financial information for the fiscal years ending 2012 through 2016 as calculated by Catalyst’s management.”

Calculations of Unlevered Free Cash Flows used in Connection with Goldman Sachs Illustrative Discounted Cash Flow Analyses

The estimates of unlevered free cash flows for Catalyst and SXC used by Goldman Sachs in its discounted cash flow analyses as described under “The Merger—Opinion of Catalyst’s Financial Advisor” were calculated using the projections and extrapolations described above, which calculations were reviewed and approved by management of Catalyst, by taking after-tax EBIT (using an assumed tax rate of 34% for 2012, 35% for 2013 and 36% for 2014 through 2016 for SXC and 38% for Catalyst) from the applicable projections (and in the case of the unlevered free cash flows calculated for SXC for the years ending December 31, 2015 and 2016, extrapolations thereof) described above and adding back estimates (and extrapolations) of depreciation and amortization, and subtracting estimates of capital expenditures (and integration expenses and cash flow for acquisitions, in the case of Catalyst) and adding (or subtracting as applicable) working capital changes. The results of these calculations were unlevered free cash flows for SXC of $83 million, $218 million, $253 million, $290 million and $331 million for the second half of the year ending December 31, 2012 and for the full years ending December 31, 2013, 2014, 2015 and 2016, respectively, and for Catalyst of $60 million, $(151) million, $(97) million, $(95) million and $(37) million for second half of the year ending December 31, 2012 and for the full years ending December 31, 2013, 2014, 2015 and 2016, respectively. SXC and its financial advisors did not participate in, or in any way verify, and made no judgments about, the estimates of unlevered free cash flows used by Goldman Sachs in its discounted cash flow analyses as described under “The Merger—Opinion of Catalyst’s Financial Advisor.”

* * *

In addition, unrelated to the litigation, SXC is supplementing disclosure solely to correct a typographical error in the number of shares of SXC common stock to be available for issuance under the Catalyst equity plan as assumed by SXC in connection with the merger. Accordingly, the following information amends the Joint Proxy Statement/Prospectus and should be read in conjunction with the Joint Proxy Statement/Prospectus:

On page 192 of the Joint Proxy Statement/Prospectus, in the last sentence of the carry-over paragraph from page 191 of the Joint Proxy Statement/Prospectus, delete the clause “approximately 1.1 million” and replace with “746,007.”

Catalyst Forward Looking Statements

Certain statements may contain certain forward-looking statements including, without limitation, statements concerning Catalyst’s operations, economic performance and financial condition. The words “believe,” “expect,” “anticipate,” “will,” “could,” “would,” “should,” “may,” “plan,” “estimate,” “intend,” “predict,” “potential,” “continue,” and the negatives of these words and other similar expressions generally identify forward-looking statements. In addition to Catalyst’s expectations or estimates of a combined company’s future performance or matters relating to the proposed transaction with SXC, these forward-looking statements may include statements addressing Catalyst’s operations and Catalyst’s financial performance. Readers are cautioned not to place undue reliance on these forward-looking statements, which, among other things, speak only as of their dates. These forward-looking statements are based largely on Catalyst’s current expectations and are based on a number of risks and uncertainties, including, without limitation, (i) general adverse economic conditions, (ii) changes in governmental laws and regulations, (iii) Catalyst’s ability to compete effectively in the pharmacy benefit management industry, (iv) Catalyst’s relationships with key clients, pharmacy network affiliations and various pharmaceutical manufacturers and rebate intermediaries, (v) changes in industry pricing benchmarks, (vi) uncertainties relating to the transition and integration of completed and future acquisitions and/or expansion opportunities, (vii) Catalyst’s current level of indebtedness and any future indebtedness Catalyst may incur; (viii) disruption in Catalyst’s operations, (ix) unanticipated changes in Catalyst’s ability to execute its growth strategy, (x) generic utilization levels, (xi) insufficient insurance coverage to cover costs associated with litigation, (xii) Catalyst’s ability to accurately estimate how much future revenue Catalyst will generate, as well as the level of implementation and transaction costs that Catalyst will incur, under newly commenced PBM agreements and other risks and uncertainties discussed in Catalyst’s filings with the SEC, including Catalyst’s Annual Report on Form 10-K and quarterly reports on Form 10-Q. Actual results could differ materially from results referred to in the forward-looking statements. In light of these risks and uncertainties, there can be no assurances that the results referred to in the forward-looking statements contained herein will, in fact, occur. Catalyst undertakes no obligation to revise any forward-looking statements in order to reflect events or circumstances that may arise after the date hereof. Readers are urged to carefully review and consider the various disclosures made in Catalyst’s other filings with the SEC that attempt to advise interested parties of the risks and factors that may affect Catalyst’s business.

Transaction Forward-Looking Statements

In addition, numerous factors could cause actual results with respect to the proposed transaction with SXC to differ materially from those in the forward-looking statements, including without limitation, the possibility that the expected efficiencies and cost savings from the proposed transaction will not be realized, or will not be realized within the expected time period; the risk that the SXC and Catalyst businesses will not be integrated successfully; the ability to obtain governmental approvals of the proposed transaction on the proposed terms and schedule contemplated by the parties; the failure of shareholders of SXC or Catalyst to approve the proposed transaction; disruption from the proposed transaction making it more difficult to maintain business and operational relationships; the risk of customer attrition; the possibility that the proposed transaction does not close, including, but not limited to, due to the failure to satisfy the closing conditions; and the ability to obtain the financing contemplated to fund a portion of the consideration to be paid in the proposed transaction and the terms of such financing.

See also “Financial Forecasts” in the Joint Proxy Statement/Prospectus for cautionary statements regarding the projections described therein. Such cautionary statements apply to the projections set forth herein.
