Name of Grantee (the “Grantee):________________________________________________

Date of Restricted Stock Award (the “Award Date”):________________________________

Number of Shares Covered by Restricted Stock Award (the “Award Shares”):____________

This Restricted Stock Award Agreement (this “Agreement”) is entered into as of the Date of Restricted Stock Award set forth above (the “Award Date”) by and between CSG SYSTEMS INTERNATIONAL, INC., a Delaware corporation (the “Company”), and the Grantee named above (the “Grantee”).

* * *

WHEREAS, the Company has adopted a 2001 Stock Incentive Plan (the “Plan”); and

WHEREAS, pursuant to the Plan, as of the Award Date the Company granted to Grantee a Restricted Stock Award (the “Award”) covering the number of shares of the Common Stock of the Company (the “Common Stock”) set forth above (the “Award Shares”) and is executing this Agreement with Grantee for the purpose of setting forth the terms and conditions of the Award;

NOW, THEREFORE, in consideration of the premises and the covenants and conditions contained herein, the Company and Grantee agree as follows:

(a) The Company hereby confirms the grant of the Award to Grantee as of the Award Date. The Award is subject to all of the terms and conditions of this Agreement.

(b) Promptly after the execution of this Agreement, the Company will cause the transfer agent for the Common Stock (the “Transfer Agent”) to (i) either establish a separate account in its records in the name of Grantee (the “Restricted Stock Account”) and credit the Award Shares to the Restricted Stock Account as of the Award Date or credit the Award Shares to a previously existing Restricted Stock Account of Grantee as of the Award Date and (ii) confirm such actions to Grantee in writing.

(a) Twenty-five percent (25%) of the Award Shares (rounded to the nearest whole number) automatically will vest in Grantee on each of the first four (4) anniversaries of the Award Date (each such anniversary being referred to in this Agreement as a “Vesting Date”); provided, however, that no Award Shares shall vest in Grantee on a particular Vesting Date unless Grantee has been continuously employed by the Company from the Award Date until such Vesting Date.

(b) For purposes of this Agreement, a “Termination of Employment” of Grantee means the effective time when the employer-employee relationship between Grantee and the Company terminates for any reason whatsoever.

(c) In determining the existence of continuous employment of Grantee by the Company or the existence of an employer-employee relationship between Grantee and the Company for purposes of this Agreement, the term “Company” shall include a Subsidiary (as defined in the Plan); and neither a transfer of Grantee from the employ of the Company to the employ of a Subsidiary nor the transfer of Grantee from the employ of a Subsidiary to the employ of the Company or another Subsidiary shall be deemed to be a Termination of Employment of Grantee.

(d) After the Grantee has become vested in any of the Award Shares and, if applicable, after the cancellation of certain of the Award Shares as provided for in Section 12(b) has occurred, the Company will instruct the Transfer Agent to remove all restrictions on the transfer, assignment, pledge, encumbrance, or other disposition of the then remaining vested Award Shares in the Restricted Stock Account. Grantee thereafter shall be free to deal with and dispose of such remaining vested Award Shares in Grantee’s sole discretion and may request the Transfer Agent to issue a certificate for such remaining vested Award Shares in Grantee’s name free of any restrictions.

Subject to the provisions of Section 15, if applicable, upon a Termination of Employment of Grantee, all of the rights and interests of Grantee in any of the Award Shares which have not vested in Grantee pursuant to Section 2 prior to such Termination of Employment of Grantee automatically shall completely and forever terminate; and, at the direction of the Company, the Transfer Agent shall remove from the Restricted Stock Account and cancel all of such unvested Award Shares.

Nothing contained in this Agreement (i) obligates the Company or a Subsidiary to continue to employ Grantee in any capacity whatsoever or (ii) prohibits or restricts the Company or a Subsidiary from terminating the employment of Grantee at any time or for any reason whatsoever. In the event of a Termination of Employment of Grantee, Grantee shall have only the rights set forth in this Agreement with respect to the Award Shares.

2

If at any time that any of the Award Shares have not vested in Grantee there is any non-cash dividend of securities or other property or rights to acquire securities or other property, any liquidating dividend of cash and/or property, or any stock dividend or stock split or other change in the character or amount of any of the outstanding securities of the Company, then in such event any and all new, substituted, or additional securities or other property to which Grantee may become entitled by reason of Grantee’s ownership of such unvested Award Shares immediately and automatically shall become subject to this Agreement, shall be delivered to the Transfer Agent or to an independent Escrow Agent selected by the Company to be held by the Transfer Agent or such Escrow Agent pursuant to the terms of this Agreement (including but not limited to the provisions of Sections 3 and 8), and shall have the same status with respect to vesting and transfer as the unvested Award Shares upon which such dividend was paid or with respect to which such new, substituted, or additional securities or other property was distributed. Any cash or cash equivalents received pursuant to the first sentence of this Section 5 shall be invested in conservative short-term interest-bearing securities, and interest earned thereon also shall have the same status with respect to vesting and transfer as the unvested Award Shares with respect to which such cash or cash equivalents were received. Cash dividends (other than liquidating dividends) paid on such unvested Award Shares shall be paid to Grantee and shall not be subject to vesting or to the first sentence of this Section 5.

Grantee hereby represents and warrants to the Company as follows:

(a) Grantee had full legal power, authority, and capacity to execute and deliver this Agreement and to perform Grantee’s obligations under this Agreement; and this Agreement is a valid and binding obligation of Grantee, enforceable in accordance with its terms, except that the enforcement of this Agreement may be subject to bankruptcy, insolvency, reorganization, moratorium, or other similar laws now or hereafter in effect relating to creditors’ rights generally and to general principles of equity (regardless of whether such enforcement is considered in a proceeding in equity or at law).

(b) Grantee is aware of the public availability on the Internet at www.sec.gov of the Company’s periodic and other filings made with the United States Securities and Exchange Commission.

The Company hereby represents and warrants to Grantee as follows:

(a) The Company is a corporation duly organized, validly existing, and in good standing under the laws of Delaware and has all requisite corporate power and authority to enter into this Agreement, to issue the Award Shares to Grantee, and to perform its obligations under this Agreement.

(b) The execution and delivery of this Agreement by the Company have been duly and validly authorized; and all necessary corporate action has been taken to make this Agreement a valid and binding obligation of the Company, enforceable in accordance with its terms, except that the enforcement of this Agreement may be subject to bankruptcy, insolvency, reorganization, moratorium, or other similar laws now or hereafter in effect relating to creditors’ rights generally and to general principles of equity (regardless of whether such enforcement is considered in a proceeding in equity or at law).

(c) When issued to Grantee as provided for in this Agreement, the Award Shares will be duly and validly issued, fully paid, and non-assessable.

None of the Award Shares that have not vested in Grantee pursuant to Section 2 (and no beneficial interest in any of such Award Shares) may be sold, transferred, assigned, pledged, encumbered, or otherwise disposed of in any way (including a transfer by operation of law); and any attempt to make any such sale, transfer, assignment, pledge, encumbrance, or other disposition shall be null and void and of no effect.

The Company and Grantee acknowledge that the Company’s remedy at law for any breach or violation or attempted breach or violation of the provisions of Section 8 will be inadequate and that, in the event of any such breach or violation or attempted breach or violation, the Company shall be entitled to injunctive relief in addition to any other remedy, at law or in equity, to which the Company may be entitled.

Neither the Company nor the Transfer Agent shall be required to transfer on the stock records of the Company maintained by either of them any Award Shares which have been sold, transferred, assigned, pledged, encumbered, or otherwise disposed of in violation of any of the provisions of this Agreement or to treat as the owner of such Award Shares or accord the right to vote or receive dividends to any purported transferee or pledgee to whom such Award Shares shall have been so sold, transferred, assigned, pledged, encumbered, or otherwise disposed of in violation of any of the provisions of this Agreement.

Grantee shall have the right to make an election pursuant to Treasury Regulation § 1.83-2 with respect to the Award Shares and, if Grantee makes such election, promptly will furnish to the Company a copy of the form of election Grantee has filed with the Internal Revenue Service for such purpose and evidence that such an election has been made in a timely manner.
