This Agreement and Employee's employment may be terminated in any of the
following ways:

(i)Death. This Agreement will terminate automatically upon Employee’s death.

(ii)Disability. If, as a result of physical or mental illness or injury,
Employee shall have been unable to perform the Employee’s duties hereunder, with

with or without reasonable accommodation at the conclusion of such notice
period. Also, Employee may terminate Employee's employment hereunder if
Employee's health should become impaired to an extent that makes the continued
performance of Employee's duties hereunder hazardous to Employee's physical or
mental health or life, provided that Employee shall have furnished the Company
with a written statement from a qualified doctor to such effect and provided,
further, that, at the Company's request

Exhibit 10.22

made within thirty (30) days of the date of such written statement, Employee
shall submit to an examination, at the Company’s expense, by a doctor selected
by the Company who is reasonably acceptable to Employee or Employee's doctor.

(iii)Termination by the Company for Cause. The Company may terminate the
Agreement immediately for Good Cause, which shall be: (1) Employee’s commission
of theft, embezzlement, forgery, any other act of dishonesty relating to
Employee’s employment with the Company and/or any affiliate or subsidiary of the
Company, or any violation of Company policies (including the Company’s ethics
policies (including any sexual harassment policies) or Code of Conduct), or any
law, rule, or regulation applicable to the Company, Genesis or Genesis Marine or
any failure by Employee to inform the Company of any violation of any law, rule
or regulation by the Company or one of its direct or indirect subsidiaries of
which Employee has knowledge; (2) Employee’s conviction of, or pleading guilty
or nolo contendere to, a felony or any lesser crime having as its predicate

during any period of disability) which failure to perform is not remedied within
thirty (30) days after notice thereof to Employee by the Company; or (4)
Employee’s commission of an act or acts in the performance or intentional
non-performance of Employee’s duties under this Agreement amounting to gross
negligence or willful misconduct (“Cause”). In the event of a termination for
Cause, Employee shall have no right to any severance compensation.

(iv)Termination by Either Party Without Cause. At any time after the
commencement of employment, the Company or Employee may, without Cause,
terminate this Agreement and Employee's employment, effective thirty (30) days
after written notice is provided to the other party (“Without Cause”).

(v)Termination by Employee for Good Reason: Employee may terminate this
Agreement for Good Reason, after providing thirty (30) days written notice to
the Company, which identifies the Good Reason for Employee’s termination. “Good
Reason” means any of the following reasons: (1) following a Change of Control
which results in a substantial diminution of Employee’s duties and
responsibilities or a material reduction of compensation or benefits; (2)
Employee’s removal from Employee’s position as Vice President, during the term
of this Agreement (other than if Employee is offered an Equivalent Position, if
Employee is removed for Cause or by death or disability, as set forth in this

or partnership interests of Genesis or substantially all of the assets of the
Company or Genesis, (ii) merger, conversion or consolidation of the Company or
Genesis, or (iii) other event, that, in the case of (i), (ii) or (iii), results
in any person or entity (or other persons or entities acting in concert) having
the ability to elect a majority of the members of the Board; provided, however,
that any such event described in (i)-(iii) above shall not constitute a Change
of Control if the relevant persons or entities in “control” are Denbury
Resources Inc., a Delaware corporation, one or more executive officers of the
Company and/or any affiliates of the foregoing. “Equivalent Position” means a
position with the Company or an affiliate of the Company with equivalent
compensation and at the same work location.

(b)Effect of Termination.

(i)Upon termination of this Agreement for any reason, Employee shall be entitled
to receive all compensation earned and all benefits and reimbursements due
through the effective date of termination. Additional compensation subsequent to
termination, if any, will be due and payable to Employee only to the extent and
in the manner expressly provided herein.

Initial Term, Employee shall receive (x) the greater of one (1) year of Base
Salary or the balance of the Base Salary due Employee for the remainder of the
Term, such sums to be paid on a monthly basis in accordance with applicable
Company policies, and (y) COBRA benefits for the total number of months
remaining in the Term of the Agreement, but in no event will the total number of
months be less than twelve months or more than 18 months. COBRA benefits will be
payable by the Company, so long as Employee elects and is eligible for said
benefits. At the discretion of the management of the Company, Employee will also
be eligible to receive his pro rata share of Employee’s annual bonus.

--------------------------------------------------------------------------------

Exhibit 10.22

(iii)If the Agreement is terminated by Employee Without Cause during the Initial
Term, all rights and obligations of the Company and Employee under this
Agreement shall cease as of the effective date of termination, except that the
Company's obligations under Sections 3(b)(i) and 5 herein and Employee's
obligations under Sections 4 and 6 herein and in the Employee’s non-compete
agreement shall survive such termination in accordance with their terms unless
otherwise provided herein.

(iv)If the Agreement is terminated by Employee for Good Reason, the Company
shall pay Employee in the same manner as provided in Sections 3(b)(i) and
3(b)(ii) above as if the Company had terminated Employee Without Cause.

(v)If the Agreement is terminated by the Company without cause or by the
Employee for Good Reason during any subsequent renewal term, Employee shall
receive (x) the balance of the Base Salary due Employee for the remainder of the
renewal term, such sums to be paid on a monthly basis in accordance with
applicable Company policies, and (y) COBRA benefits for the total number of
months remaining in the Term of the Agreement, but in no event will the total
number of months be less than twelve months or more than 18 months. COBRA
benefits will be payable by the Company, so long as Employee elects and is
eligible for said benefits. At the discretion of the management of the Company,
Employee will also be eligible to receive his pro rata share of Employee’s
annual bonus.

4.Return of Company Property. All records, designs, patents, business plans,
financial statements, manuals, memoranda, lists and any other property delivered
to, created by or compiled by Employee, by or on behalf of the Company, by
Company's affiliates or their representatives, vendors or customers which
pertain to the business of the Company or its affiliates shall be and remain the
property of the Company or its affiliates, as the case may be, and be subject at
all times to the Company’s discretion and control. Likewise, all correspondence,
reports, records, charts, advertising materials and other similar data and
documents pertaining to the business, customers, activities or future plans of
the Company or its affiliates which is in the Employee’s possession, custody or
control, whether prepared by the Employee or others, shall be delivered promptly
to the Company (within 24 hours) without request by the Company upon termination
of Employee's employment.

5.Indemnification. In the event Employee would incur any expense or liability in
connection with any threatened, pending, contemplated or completed action, suit
or proceeding, whether civil, criminal, administrative or investigative (other
than an action by the Company or its affiliates against Employee)
(“Proceeding”), any appeal to such a Proceeding, any inquiry or investigation
that could lead to a Proceeding, by reason of the fact that Employee is or was
performing services under this Agreement or by reason of the fact that Employee
is an officer of the Company, then the Company shall indemnify Employee against
all expenses (including reasonable attorneys' fees and costs), judgments, fines,
and amounts paid in settlement, as actually and reasonably incurred by Employee
in connection therewith. In the event that both Employee and the Company are
made a party to the same third-party action, complaint, suit or Proceeding, the
Company agrees to engage counsel, and Employee agrees to use the same counsel,
provided that if counsel selected by the Company shall have a conflict of
interest that prevents such counsel from representing Employee, Employee may
engage separate counsel and the Company shall pay all reasonable attorneys' fees
of such separate counsel. The Company shall not be required to pay the fees of
more than one law firm except as described in the preceding sentence and shall
not be required to pay the fees of more than two law firms under any
circumstances. Further, while Employee is expected at all times to use
Employee's best efforts to faithfully discharge Employee's duties under this
Agreement, Employee cannot be held liable to the Company for errors or omissions
made in good faith, and Employee will be indemnified as described above, except
where Employee has exhibited gross, willful and wanton negligence and misconduct
or performed criminal and fraudulent acts which materially damage the business
of the Company. The indemnification provided under this Section 5 is
non-exclusive and shall in no way limit any indemnification provided by
applicable law or any indemnification provision of the Company’s, Genesis’ or
Genesis Marine’s charter or organizational documents.

6.No Prior Agreements. Employee represents and warrants that to Employee’s
knowledge Employee has no obligations, legal, in contract, or otherwise,
inconsistent with the terms of this Agreement or with Employee’s undertaking
employment with the Company to perform the duties described herein. Employee
will not disclose to the Company or any of its affiliates, or use, or induce the
Company or any of its affiliates to use, any confidential, proprietary, or trade
secret information of others. Employee represents and warrants that to
Employee’s knowledge, Employee has returned all property and confidential
information belonging to all prior employers, if Employee is obligated to do so.
Employee agrees to indemnify the Company

--------------------------------------------------------------------------------

Exhibit 10.22

for any Proceeding, including, but not limited to, all expenses (including
reasonable attorneys' fees and costs), judgments, fines, and amounts paid in
settlement, as actually and reasonably incurred by the Company in connection
therewith, including any investigation of the same, by any such third party that
such third party may now have or may hereafter come to have against the Company
based upon or arising out of any non-competition agreement, invention or
confidential information, trade secret or secrecy agreement or like agreement
between Employee and such third party which was in existence as of the date of
this Agreement, should the third party prevail in such proceeding against the
Company.

7.Entire Agreement.    This agreement constitutes the entire agreement between
the parties and supersedes any prior understandings, agreement or
representations by or between the parties (other than those contained in any
confidentiality or non-compete agreement dated as of the date hereof between

extent they have related in any way to the subject matter hereof.

8.Assignment; Binding Effect. Employee understands that Employee has been
selected for employment by the Company on the basis of Employee's personal
qualifications, experience and skills. Employee agrees, therefore, that Employee
cannot assign all or any portion of Employee's performance under this Agreement.

benefit of and be enforceable by the parties hereto and their respective heirs,
legal representatives, successors and assigns.
