WHEREAS, , the parties deem it desirable to formally amend the Agreement to

Executive’s position and title shall be Executive Vice President and Global
Co-Chief Investment Officer of the Company, CAM and Holdings.”

b.
Section 4 is deleted in its entirety and replaced with the words “Intentionally
left blank”.

c.
All references to “Incentive Payments” are deleted. The text in Sections
6(a)(iii), 6(b)(iv) and 6(d)(i)(C)(4) shall be replaced with the words
“Intentionally left blank”. Section 6(c)(ii) shall be revised where the sentence
shall be truncated after the words “not theretofore paid” and the “(i)”
reference shall be deleted.

2.
Effective Dates. The change relating to Positions and Titles was effective as of

elimination of Incentive Payments for the Executive and the corresponding
withdrawal of Executive’s membership in Calamos Capital Management LLC and (iii)

of such conflicts) in relation to fiduciary and other obligations the Company
and its affiliates owe to investment advisory clients, while providing the
Executive with the opportunity to earn over time benefits substantially
equivalent to those that would be earned under Section 4 (prior to deletion)
over time.

force and effect. Unless otherwise provided herein, defined terms shall have the
