INVESTOR SECURITIES PURCHASE AGREEMENT

This INVESTOR SECURITIES PURCHASE AGREEMENT (this “Agreement”), is entered into as of September 22, 2008, by and among CT Technologies Holdings, LLC, a Delaware limited liability company (the “Company”), and the persons listed on Schedule A hereto (each, an “Investor” and collectively, the “Investors”). Certain defined terms have the meanings given to those terms in Section 3 below.

WHEREAS, in connection with the acquisition of Companion Technologies Corporation pursuant to that certain Stock Purchase Agreement dated as of December 31, 2006 by and among Blue Cross and Blue Shield of South Carolina and the Company, the Company issued Series A Shares to certain of the Investors pursuant to the Investors Securities Purchase Agreement dated as of December 29, 2006 (the “Original Agreement”).

WHEREAS, (a) pursuant to Section l(d) of the Original Agreement, ABRY, as an affiliate of ABRY V, and (b) each other Investor set forth on Schedule A attached hereto, desire to purchase from the Company, and the Company desires to sell to the Investors, the Company’s Series A Shares (the “Series A Shares”), in the respective quantities and for the respective prices set forth on Schedule A hereto, as the case may be, subject to the terms and conditions set forth in this Agreement.

NOW THEREFORE, for good and valuable consideration, the receipt and sufficiency of which the parties acknowledge, the Company and the Investors agree as follows:

1. Purchase and Sale of Shares.

(a) Subject to the terms and conditions of this Agreement, on the Closing Date, each Investor will purchase, and the Company will sell, the number of Series A Shares set forth opposite such Investor’s name on Schedule A for the aggregate consideration set forth opposite such Investor’s name on Schedule A (the “Purchase Price”). The issuance of any Series A Shares hereunder is conditioned upon the contemporaneous closing of the transactions contemplated under the Merger Agreement. On the Closing Date, each Investor will deliver to the Company (or its designee) a wire transfer of immediately available funds in the aggregate amount of the Purchase Price payable by such Investor.

(b) In connection with the purchase and sale of Series A Shares under this Agreement, each Investor, severally and not jointly, represents and warrants to the Company that the following statements are true on the date hereof and will be true on the Closing Date as if made on such date:

(i) The Series A Shares to be acquired by such Investor pursuant to this Agreement will be acquired for such Investor’s own account and not with a view to, or intention of, distribution thereof in violation of the Securities Act, any applicable state securities laws or the terms of the LLC Agreement or the Members Agreement, and such Series A Shares will not be disposed of in contravention of any such laws or agreement.

1

(ii) Such Investor is an accredited investor as such term is defined in Regulation D promulgated pursuant to Section 4(2) of the Securities Act. Such Investor acknowledges and agrees that the Series A Shares are being sold in reliance on an exemption from registration under the Securities Act and exemptions contained in applicable state securities laws, and that the Series A Shares cannot and may not be sold or transferred except in a transaction that is exempt under the Securities Act and those state acts or pursuant to an effective registration statement under the Securities Act and those state acts or in a transaction that is otherwise in compliance with the Securities Act and those state acts. Such Investor understands that it has no contractual right for the registration under the Securities Act of the Series A Shares for public sale (other than under the Registration Rights Agreement) and that, unless the Series A Shares are registered or an exemption from registration is available, the Series A Shares may be required to be held indefinitely.

(iii) Such Investor is able to bear the economic risk of the investment in Series A Shares for an indefinite period of time, and such Investor understands that Series A Shares are subject to the transfer restrictions contained herein and have not been registered under the Securities Act.

(iv) Such Investor has had an opportunity to ask questions and receive answers concerning the terms and conditions of the offering of Series A Shares and has had full access to such other information concerning the Company as such Investor has requested. Such Investor has reviewed, or has had an opportunity to review copies of the following documents, (A) the Members Agreement, (B) the LLC Agreement (C) the Registration Rights Agreement, and (D) the Merger Agreement that the Company is entering into on the date of this Agreement.

(v) Each of this Agreement, the LLC Agreement, the Members Agreement and the Registration Rights Agreement constitutes the legal, valid and binding obligation of such Investor, enforceable against such Investor in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and limitations on the availability of equitable remedies and the execution, delivery, and performance of each such Agreement by such Investor does not and will not conflict with, violate, or cause a breach of any agreement, contract, or instrument to which such Investor is a party or any judgment, order, or decree to which such Investor is subject.

(vi) As an inducement to the Company to sell the Series A Shares to such Investor, such Investor acknowledges and agrees that the Company and the other Investors shall have no duty or obligation to disclose to such Investor, and such Investor shall have no right under this Agreement to be advised of, any material information regarding the Company or any of its Subsidiaries at any time after the date of this Agreement.

(c) In connection with the purchase and sale of Series A Shares under this Agreement, the Company represents and warrants to each Investor that the following statements are true on the date hereof and will be true on the Closing Date as if made on such date:

(i) Organization, Corporate Power. The Company is a limited liability company duly organized, validly existing and in good standing under the laws of the State of Delaware and is qualified to do business and is in good standing in every jurisdiction in which the failure to do so would not, or would not reasonably be expected to, have a material adverse effect on the assets, operations, business or financial condition of the Company and its Subsidiaries taken as a whole. The Company possesses all requisite power and authority necessary to own and operate its properties, to carry on its businesses as presently conducted and as proposed to be conducted and to carry out the transactions contemplated by this Agreement.

(ii) Series A Shares Duly Authorized. When issued pursuant to this Agreement, all of the Series A Shares will be duly authorized and validly issued and outstanding, and will have been issued by the Company in compliance with applicable federal and state securities laws.

(iii) Authorization; Enforceability. The execution, delivery and performance by the Company or its officers of this Agreement, the LLC Agreement, the Members Agreement, the Registration Rights Agreement and all other agreements contemplated by this Agreement and such other Agreements to which the Company is a party and the offer, sale and issuance of Series A Shares have been duly authorized by the Company. This Agreement, the LLC Agreement, the Members Agreement, the Registration Rights Agreement, the Original Agreement and all such other agreements to which the Company is a party each constitute a valid and binding obligation of the Company, enforceable in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors’ rights generally and limitations on the availability of equitable remedies.

(iv) Brokerage. There are no claims for brokerage commissions, finders’ fees or similar compensation in connection with the transactions contemplated by this Agreement based on any arrangement or agreement binding upon the Company. The Company will pay, and hold each Investor harmless against, any liability, loss or expense (including reasonable attorneys’ fees and out-of-pocket expenses) arising in connection with any such claim.

(v) Capitalization. Immediately after the consummation of the transactions contemplated under Section 1 hereof, the equity capitalization of the Company will be as set forth on Schedule 1 attached hereto.

(vi) Private Offering; Consents and Approvals. No consent, approval, order, or authorization of, or registration, qualification, designation, declaration, or filing with, any federal, state, or local governmental authority on the part of the Company is required in connection with the offer, sale, or issuance of the Series A Shares or the consummation of any other transaction contemplated hereby, except for compliance with applicable state securities laws, which compliance will have occurred within the appropriate time periods therefor. Assuming that the representations of the Investors set forth in Section l(b) hereto are true and correct, the offer, sale, and issuance of the Series A Shares in conformity with the terms of this Agreement are exempt from the registration requirements of Section 5 of the Securities Act, and from the qualification requirements of each applicable state securities laws, and neither the Company nor any authorized agent acting on its behalf will take any action hereafter that would cause the loss of such exemptions.

3

(vii) Registration Rights; Voting Rights. Other than pursuant to the Registration Rights Agreement, the Company has not granted or agreed to grant, and is not under any obligation to provide, any rights to register under the Securities Act any of its presently outstanding securities or any of its securities that may be issued subsequently, and to the Company’s knowledge, except as set forth in the LLC Agreement and the Members Agreement, no stockholder of the Company has entered into any agreement with respect to the voting of equity securities of the Company.

(viii) Notwithstanding anything to the contrary in this Agreement, the issuance of Series A Shares pursuant to this Agreement does not (i) require the Company to register under the Investment Company Act of 1940, as amended from time to time, (ii) cause the Company to have more than 100 partners (within the meaning of Treasury Regulation Section 1.7704-l(h), including the look-through rule in Treasury Regulation Section 1.7704-l(h)(3)), (iii) affect the Company’s existence or qualification as a limited liability company under the Delaware Limited Liability Company Act, as the same may be amended from time to time, (iv) cause the Company to be classified as other than a partnership for United States federal income tax purposes or (v) result in a termination of the Company under Code Section 708, unless the board of directors of the Company has determined that any such termination will not have a material adverse impact on the Members, or (vi) cause the application of the tax-exempt use property rules of Code Sections 168(g)(l)(B) and 168(h) to the Company or its Members.

(d) Reduction of ABRY Commitment. The parties acknowledge that ABRY’s acquisition of Series A Units hereunder is made in accordance with Section l(d) of the Original Agreement and, therefore, the amount of ABRY’s investment hereunder shall reduce the $40 million commitment of ABRY V (and its affiliates and co-investors) described in Section l(d) of the Original Agreement on a dollar for dollar basis. The Company further acknowledges that, following the transactions contemplated hereby, such $40 million commitment is fully funded and satisfied pursuant to Section l(d) of the Original Agreement.
