If Executive fails to comply with the covenants set forth in SECTION 11 or if Executive fails to execute the Release or revokes the Release during the seven (7)-day period 10 following his execution of the Release, then Executive shall not be entitled to any severance payments or other benefits to which Executive would otherwise be entitled under SECTION 5(d) or (e). 6. Additional Payments. If it is determined that any amount, right or benefit paid or payable (or otherwise provided or to be provided) to Executive by the Company or any of its affiliates under this Agreement or any other plan, program or arrangement under which Executive participates or is a party (collectively, the "PAYMENTS"), would constitute an "excess parachute payment" within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended from time to time (the "CODE"), subject to the excise tax imposed by Section 4999 of the Code, as amended from time to time (the "EXCISE TAX"), then Executive shall be entitled to receive an additional payment from the Company (a "GROSS-UP PAYMENT") in an amount such that, after payment by Executive of all taxes (including any interest or penalties imposed with respect to such taxes), including any income and employment taxes (and any interest and penalties imposed with respect thereto) and Excise Tax imposed upon the Gross-Up Payment (and any interest and penalties imposed with respect thereto), Executive retains an amount of the Gross-Up Payment equal to the Excise Tax (including any interest and penalties imposed with respect thereto) imposed upon the Payments. All determinations required to be made under this SECTION 6, including whether and when a Gross-Up Payment is required, the amount of such Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by an independent, nationally recognized accounting firm mutually acceptable to the Company and Executive (the "AUDITOR"). The Auditor shall provide detailed supporting calculations to both the Company and Executive within fifteen (15) business days of the receipt of notice from Executive or the Company that there has been a Payment, or such earlier time as is requested by the Company. All fees and expenses of the Auditor shall be paid by the Company. Any Gross-Up Payment, as determined pursuant to this SECTION 6, shall be paid by the Company to Executive within five (5) days of the receipt of the Auditor's determination. All determinations made by the Auditor shall be binding upon the Company and Executive; provided that if, notwithstanding the Auditor's initial determination, the Internal Revenue Service (or other applicable taxing authority) determines that an additional Excise Tax is due with respect to the Payments, then the Auditor shall recalculate the amount of the Gross-Up Payment based upon the determinations made by the Internal Revenue Service (or other applicable taxing authority) after taking into account any additional interest and penalties (the "RECALCULATED AMOUNT") and the Company shall pay to Executive the excess of the Recalculated Amount over the Gross-Up Payment initially paid to Executive within five (5) days of the receipt of the Auditor's recalculation of the Gross-Up Payment. 7. Non-exclusivity of Rights. Nothing in this Agreement shall prevent or limit Executive's continuing or future participation in any benefit, bonus, incentive or other plan or program provided by the Company and for which Executive may qualify, nor shall anything herein limit or otherwise affect such rights as Executive may have under any stock option, restricted shares or other agreement with the Company or any of its affiliated companies. Except as otherwise provided herein, amounts and benefits which are vested benefits or which Executive is otherwise entitled to receive under any plan, program, agreement or arrangement of the Company at or subsequent to the Date of Termination shall be payable in accordance with such plan or program. 8. No Set-Off; No Mitigation. Except as provided herein, the Company's obligation to make the payments provided for in this Agreement and otherwise to perform its obligations 11 hereunder shall not be affected by any circumstances, including any set-off, counterclaim, recoupment, defense or other right which the Company may have against Executive or others. In no event shall Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to Executive under any of the provisions of this Agreement, and such amounts shall not be reduced whether or not Executive obtains other employment, other than as provided in SECTION 5(d)(iv). 9. Arbitration of Disputes. Except as set forth in SECTION 11(g), any controversy or claim arising out of or related to (A) this Agreement, (B) the breach thereof or (C) Executive's employment with the Company or the termination of such employment shall be settled by arbitration in Chicago, Illinois before a single arbitrator administered by the American Arbitration Association ("AAA") under its National Rules for the Resolution of Employment Disputes, effective as of January 1, 2004 (the "EMPLOYMENT RULES"), and judgment on the award rendered by the arbitrator may be entered in any court having jurisdiction thereof. Notwithstanding the foregoing, Rule R-34 of the AAA's Commercial Arbitration Rules amended and restated as of July 1, 2003 (instead of Rule 27 of the Employment Rules), shall apply to interim measures. References herein to any arbitration rule(s) shall be construed as referring to such rule(s) as amended or renumbered from time to time and to any successor rules. References to the AAA include any successor organization. 10. Entire Agreement.

For purposes of this Agreement, "Confidential Information" shall mean trade secrets and other proprietary information concerning the products, processes or services of the Company or any of its affiliates, which information (i) has not been made generally available to the public, and is useful or of value to Company's current or anticipated business activities or of those of any affiliate or client of Company; or (ii) has been identified to Executive as confidential, either orally or in writing, including, but not limited to: computer programs; research and other statistical data and analyses; marketing, organizational or other research and development, or business plans; personnel information, including the identity of other Executives of the Company, their responsibilities, competence, abilities, and compensation; financial, accounting and similar records of Company, its affiliates and/or any Fund or account managed by the Company or its affiliates (such Funds or accounts referred to herein as "Company Funds"); current and prospective client lists and information on clients and their Executives; client investment objectives, the nature of their investment portfolios and contractual agreements with the Company or its affiliates; information concerning planned or pending investment products, acquisitions or divestitures; and information concerning the marketing and/or sale or distribution of equity interests in the Funds. Confidential Information shall not include information which: (a) is in or hereafter enters the public domain through no fault of Executive; (b) is obtained by Executive from a third party having the legal right to use and disclose the same; or (c) is in the possession of Executive prior to receipt from the Company (as evidenced by Executive's written records pre-dating the date of employment). All notes, reports, plans, published memoranda or other documents created, developed, generated or held by Executive during employment, concerning or related to the Company's or its affiliates business, and whether containing or relating to Confidential Information or not, and all tangible personal property of the Company or its affiliates entrusted to Executive or in Executive's direct or indirect possession or control, are the property of the Company, and will be promptly delivered to the Company and not thereafter used by Executive upon termination of Executive's employment for any reason whatsoever. (c) Non-Disclosure. Executive agrees that during employment with the Company (including any employment following the Term) and at all times thereafter, Executive shall not reveal to any competitor or other person or entity (other than current employees of the Company) any Confidential Information regarding Clients (as defined herein) that Executive obtains while 13 performing services for the Company, except as may be required in Executive's reasonable judgment to fulfill his duties hereunder. (d) Non-Compete. During the term of Executive's employment with the Company and, after such termination of employment, for a period after such termination ending upon the later of the fifth anniversary of the IPO or this third anniversary of the Date of Termination (such period the "POST-TERMINATION NON-COMPETE PERIOD"), Employee shall not engage in, or own or control any interest in, or act as an officer, director or employee of, or consultant, advisor or lender to any firm, corporation, institution, business or entity (each an "Entity") directly or indirectly engaged in the Business. (e) "Calamos" Name. Employee understands that Company's name, the name of any Funds and accounts managed by the Company (such proprietary Funds, accounts and any other client account managed by the Company, the "COMPANY ACCOUNTS") and the investment performance of any Company Account and Company's relationships with its clients and employees are extremely valuable and are the result of the expenditure of substantial time, effort and resources by the Company. Therefore, during the period of Executive's employment and the Post-Termination Non-Compete Period, Employee agrees that he will not, directly or indirectly, on his or her behalf or another's behalf: (i) solicit the Company's or its affiliates' clients to provide, offer to provide, or provide to any such clients, services or products of the kind generally offered or provided by Company or its affiliates; or (ii) solicit, induce or encourage any person who is then in the employ of the Company to leave his or her employment, agency or office with Company, or employ or be employed with any such person or persons, for the purpose of providing or offering to provide, services or products of the kind generally offered by Company or its affiliates; or (iii) refer to the Company, "Calamos", "Calamos Investments" or "Calamos Asset Management" or any other name used by the Company, any Company Account or the investment performance thereof, or Executive's prior association with the Company or its affiliates or any Company Account in any public filing or in any advertisement or marketing of any service or product which is a Competing Activity; or (iv) maintain a relationship of the type described in paragraph (d) above with any Entity which refers to the Company, any Company Account or the investment performance thereof, or Executive's prior association with Company or any Company Account in any public filing or in any advertisement or marketing of any service or product which is a Competing Activity. (f) Notwithstanding the foregoing, nothing in paragraph (d) or (e) of this SECTION 11 shall prohibit Executive from engaging in Permitted Activities or prohibit Executive or any other person or Entity from referring to information described in said paragraphs, provided such reference is not made in advertising or marketing in newspapers, magazines, trade journals or other public media, or direct advertising or marketing materials, and such information is limited to the 14 extent that (i) such information is contained in any SEC filings previously made by the Company, or (ii) reference to such information is otherwise required by law. The Company and Employee agree that, based on applicable rules, regulations and court decisions in effect as of the date this Agreement is entered into, information relating to the investment performance of any Company Account is not information reference to which "is otherwise required by law" within the meaning of said clause (ii). In addition, this SECTION 11 shall not prohibit the Executive from being a passive owner of not more than two percent (2%) of the outstanding shares of any class of securities of an Entity whose securities are publicly traded, so long as Executive does not have any active participation in the business of such Entity. (g) Non-Exclusive Remedy for Restrictive Covenants. Executive acknowledges and agrees that the covenants set forth in this SECTION 11 (collectively, the "RESTRICTIVE COVENANTS") are reasonable and necessary for the protection of the Company's business interests, that irreparable injury will result to the Company if Executive breaches any of the terms of the Restrictive Covenants, and that in the event of Executive's actual or threatened breach of any such Restrictive Covenants, the Company will have no adequate remedy at law. Executive accordingly agrees that in the event of any actual or threatened breach by him of any of the Restrictive Covenants, the Company shall be entitled to immediate temporary injunctive and other equitable relief, without the necessity of showing actual monetary damages or the posting of bond. Nothing contained herein shall be construed as prohibiting the Company from pursuing any other remedies available to it for such breach or threatened breach, including the recovery of damages. The duration of a Restrictive Covenant shall be extended by such time during which such breach or threatened breach continues without cure by Executive. 12. Indemnification. (a) The Company agrees that if Executive is made a party to or involved in, or is threatened to be made a party to or otherwise to be involved in, any action, suit or proceeding, whether civil, criminal, administrative or investigative (a "PROCEEDING"), by reason of the fact that he is or was a director, officer or employee of the Company or is or was serving at the request of the Company as a director, officer, member, employee or agent of another corporation, limited liability corporation, partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether or not the basis of such Proceeding is Executive's alleged action in an official capacity while serving as a director, officer, member, employee or agent, Executive shall be indemnified and held harmless by the Company against any and all liabilities, losses, expenses, judgments, penalties, fines and amounts reasonably paid in settlement in connection therewith, and shall be advanced reasonable expenses (including attorneys' fees) as and when incurred in connection therewith, to the fullest extent legally permitted or authorized by the Company's By-laws or, if greater, by the laws of the State of Delaware, as may be in effect from time to time. The rights conferred on Executive by this SECTION 12(a) shall not be exclusive of any other rights which Executive may have or hereafter acquire under any statute, the By-laws, agreement, vote of stockholders or disinterested directors, or otherwise. The indemnification and advancement of expenses provided for by this SECTION 12 shall continue as to Executive after he ceases to be a director, officer or employee and shall inure to the benefit of his heirs, executors and administrators. 15 (b) During the Term and thereafter for the duration of any statute of limitations or other period during which a claim might be successfully brought against Executive, Executive shall be covered to the same extent as directors by any directors' and officers' liability insurance policy maintained by the Company from time to time. 13. Successors. (a) This Agreement is personal to Executive and, without the prior written consent of the Company, shall not be assignable by Executive otherwise than by will or the laws of descent and distribution. This Agreement shall inure to the benefit of and be enforceable by Executive's legal representatives. (b) This Agreement shall inure to the benefit of and be binding upon the Company and its successors. It shall not be assignable by the Company or its successors except in connection with the sale or other disposition of all or substantially all the assets or business of the Company. The Company shall require any successor to all or substantially all of the business or assets of the Company, whether direct or indirect, by purchase, merger, consolidation, acquisition of stock, or otherwise, by an agreement in form and substance reasonably satisfactory to Executive, expressly to assume and agree to perform this Agreement in the same manner and to the same extent as the Company would be required to perform if no such succession had taken place. 14. Amendment; Waiver. This Agreement contains the entire agreement between the parties with respect to the subject matter hereof and may be amended, modified or changed only by a written instrument executed by Executive and the Company. No provision of this Agreement may be waived except by a writing executed and delivered by the party sought to be charged. Any such written waiver will be effective only with respect to the event or circumstance described therein and not with respect to any other event or circumstance, unless such waiver expressly provides to the contrary. 15.

For valuable consideration, the adequacy of which is hereby acknowledged, the undersigned ("EXECUTIVE"), for himself, his spouse, heirs, administrators, children, representatives, executors, successors, assigns, and all other persons claiming through Executive, if any (collectively, "RELEASERS"), does hereby release, waive, and forever discharge Calamos Asset Management, Inc., Calamos Holdings LLC and Calamos Advisors, LLC (collectively "COMPANY"), Company's Subsidiaries, parents, affiliates, related organizations, employees, officers, directors, attorneys, successors, and assigns (collectively, the "RELEASEES") from, and does fully waive any obligations of Releasees to Releasers for, any and all liability, actions, charges, causes of action, demands, damages, or claims for relief, remuneration, sums of money, accounts or expenses (including attorneys' fees and costs) of any kind whatsoever, whether known or unknown or contingent or absolute, which heretofore has been or which hereafter may be suffered or sustained, directly or indirectly, by Releasers in consequence of, arising out of, or in any way relating to Executive's employment with Company or any of its affiliates and the termination of Executive's employment. The foregoing release and discharge, waiver and covenant not to sue includes, but is not limited to, all claims and any obligations or causes of action arising from such claims, under common law including wrongful or retaliatory discharge, breach of contract (including but not limited to any claims under the Executive Employment Agreement between the Company and Executive, dated _____________, as amended from time to time (the "EMPLOYMENT AGREEMENT") and any claims under any stock option and restricted shares agreements between Executive and the Company) and any action arising in tort including libel, slander, defamation or intentional infliction of emotional distress, and claims under any federal, state or local statute including Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1866 and 1871 (42 U.S.C. Section 1981), the National Labor Relations Act, the Age Discrimination in Employment Act (ADEA), the Fair Labor Standards Act, the Americans with Disabilities Act of 1990, the Rehabilitation Act of 1973, the Illinois Human Rights Act, or the discrimination or employment laws of any state or municipality, and/or any claims under any express or implied contract which Releasers may claim existed with Releasees. This also includes a release by Executive of any claims for breach of contract, wrongful discharge and all claims for alleged physical or personal injury, emotional distress relating to or arising out of Executive's employment with Company or the termination of that employment; and any claims under the WARN Act or any similar law, which requires, among other things, that advance notice be given of certain work force reductions. This release and waiver does not apply to any claims or rights that may arise after the date Executive signs this General Release. The foregoing release does not apply to (a) any claims or rights for severance pay, benefits, indemnification and any other surviving rights now existing under the Employment Agreement, the organization documents of the Company or any other agreement providing for indemnification regardless of when any claim is filed, (b) any claims or rights under directors and officers liability insurance. 2. Excluded from this release and waiver are any claims which cannot be waived by law, including but not limited to the right to participate in an investigation conducted by certain government agencies.

Executive represents and warrants that Executive has not filed any complaint, charge, or lawsuit against the Releasees with any government agency or any court. 3. Executive agrees never to sue Releasees in any forum for any claim covered by the above waiver and release language, except that Executive may bring a claim under the ADEA to challenge this General Release. If Executive violates this General Release by suing Releasees, other than under the ADEA or as otherwise set forth in SECTION 1 hereof, Executive shall be liable to the Company for its reasonable attorneys' fees and other litigation costs incurred in defending against such a suit. Nothing in this General Release is intended to reflect any party's belief that Executive's waiver of claims under ADEA is invalid or unenforceable, it being the interest of the parties that such claims are waived. 4. Executive acknowledges and recites that: (a) Executive has executed this General Release knowingly and voluntarily; (b) Executive has read and understands this General Release in its entirety; (c) Executive has been advised and directed orally and in writing (and this subparagraph (c) constitutes such written direction) to seek legal counsel and any other advice he wishes with respect to the terms of this General Release before executing it; (d) Executive's execution of this General Release has not been forced by any employee or agent of the Company, and Executive has had an opportunity to negotiate about the terms of this General Release; and (e) Executive has been offered twenty-one (21) calendar days after receipt of this General Release to consider its terms before executing it. 5. This General Release shall be governed by the internal laws (and not the choice of laws) of the State of Illinois, except for the application of preemptive Federal law. 6. Executive shall have seven (7) days from the date hereof to revoke this General Release by providing written notice of the revocation to the Company, as provided in SECTION 15(d) of the Employment Agreement, in which event this General Release shall be unenforceable and null and void.
