Re: Offer of Employment

Dear Correne:

Callon Petroleum Company (“Callon” or the “Company”) is pleased to offer you the
position of Treasurer, reporting to me and based in our Houston office.

The compensation package is summarized as follows:

•
A base salary of Two Hundred Forty Five Thousand Dollars ($245,000) per year.

•
An initial grant of Thirty Five Thousand (35,000) shares of restricted stock
units which will vest annually over a three-year period, commencing on March 1,
2018. Stock will only vest if you are an active employee on the date of vesting,
or in the event of a change in control of the Company.

•
Beginning with a cash bonus for calendar year 2017 (generally payable in the
first quarter of the following year), participation in the Company’s annual
incentive compensation program funded from a pool tied to goals established by
the Company’s Board of Directors. Individual awards are allocated based on both
Company and individual performance. The initial target cash bonus compensation
would be 50% to 60% of base salary.

•
Participation in Callon’s Long-Term Incentive (“LTI”) program, including grants
of (i) restricted stock units and (ii) phantom stock units payable in cash based
on the Company’s performance relative to a designated peer group. Based upon
recent years, the initial target LTI compensation would be approximately 50% to
60% of base salary. Currently, the LTI awards are allocated 40% to restricted
stock units and 60% to phantom stock units.

Participation in the Company’s 401(k) program beginning on the first day of the
first full month of employment. Currently, the Company contributes five percent
of annual base salary (2.5% in cash, 2.5% in Callon stock) with no contribution
from the employee. In addition, if you choose to make an elective deferral, the
Company will match your contribution at the rate of 0.625% for each 1% you
contribute, limited to 5% matching by the Company. The employee annual
contribution is limited by standard governmental guidelines.

•
Participation in the Callon Petroleum Company Group Insurance Plan which
currently includes medical and dental insurance coverage for employee and
qualified dependents; group term life insurance equal to 2.5 times your annual
salary; accidental death and personal loss insurance at the same rate as life
