 Exhibit 4.4 

NAVIGATOR HOLDINGS LTD. 

STOCK OPTION AGREEMENT 

(US EMPLOYEES) 
 THIS
STOCK OPTION AGREEMENT (this “Agreement”) evidences an award made as of the          day of
                                         (the
“Date of Grant”), between NAVIGATOR HOLDINGS LTD., a Marshall Islands Corporation (the “Company”), and
                                        (the 
“Employee”). 
 1. The Grant. Pursuant to the NAVIGATOR HOLDINGS LTD. 2013 LONG-TERM INCENTIVE
PLAN, as the same may be amended from time to time (the “Plan”), and subject to the conditions set forth below, the Company hereby awards to the Employee, effective as of the Date of Grant, the right and option to
purchase (the “Option”) an aggregate number of                      shares (the “Option Shares”) of
the Company’s common stock, par value $0.01 per share (“Common Stock”), at an Exercise Price equal to $         per share (the “Exercise Price”), in
accordance with the terms and conditions set forth herein and in the Plan (the “Award”). To the greatest extent permitted pursuant to Section 422 of the Code, this Option is intended to be an Incentive Stock Option. To
the extent any provision of this Agreement conflicts with the expressly applicable terms of the Plan, those terms of the Plan shall control, and if necessary, the applicable terms of this Agreement shall be deemed amended so as to carry out the
purpose and intent of the Plan. 
 2. Definitions. Capitalized terms used in this Agreement that are not defined below or in
the body of this Agreement shall have the meanings given to them in the Plan. In addition to the terms defined in the body of this Agreement, the following capitalized words and terms shall have the meanings indicated below: 

(a) “Cause” shall have the meaning set forth in any written employment or consulting agreement between the Company (or
one of its affiliates) and the Employee. If the Employee is not party to such an agreement that defines these terms, then for purposes of this Agreement, “Cause” shall mean a determination by the Company or its employing affiliate (the
“Employer”) that the Employee (i) has engaged in gross negligence, gross incompetence, or misconduct in the performance of the Employee’s duties with respect to the Employer or any of their affiliates; (ii) has
failed without proper legal reason to perform the Employee’s duties and responsibilities to the Employer or any of its affiliates; (iii) has breached any material provision of this Agreement or any written agreement or corporate policy or code
of conduct established by the Employer or any of its affiliates; (iv) has engaged in conduct that is, or could reasonably expected to be, materially injurious to the Employer or any of its affiliates; (v) has committed an act of theft,
fraud, embezzlement, misappropriation, or breach of a fiduciary duty to the Employer or any of its affiliates; or (vi) has been convicted of, pleaded no contest to, or received adjudicated probation or deferred adjudication in connection with a
crime involving fraud, dishonesty, or moral turpitude or any felony (or a crime of similar import in a foreign jurisdiction). 






 (b) “Disability” shall have the meaning set forth in any written
employment or consulting agreement between the Company (or one of its affiliates) and the Employee. If the Employee is not party to such an agreement that defines these terms, then for purposes of this Agreement, “Disability” shall mean
the Employee being unable to perform the Employee’s duties or fulfill the Employee’s obligations under the terms of his employment by reason of any medically determinable physical or mental impairment that can be expected to result in
death or can be expected to last for a continuous period of not less than three months as determined by the Employer and certified in writing by a competent medical physician selected by the Employer. 

(c) “Involuntary Termination” shall mean a termination of the Employee’s employment by the Company or an affiliate
for a reason other than for Cause. 
 3. Exercise. 

(a) Option Shares shall be deemed “Nonvested Shares” unless and until they become “Vested
Shares”. Subject to other terms and conditions set forth herein, the Option shall vest and become exercisable as to the specified percentage of Option Shares on the applicable dates set forth in the following vesting schedule, provided
that the Employee has been continuously employed by the Company from the Date of Grant through such date(s): 
  

			
	 Vesting Date
	  	Percentage of Option Shares that become
Vested and Exercisable
		  	
		  	
		  	
		  	

 Notwithstanding the schedule set forth above, if the Employee’s employment with the Company is terminated
by reason of death or Disability or due to an Involuntary Termination, then all Option Shares shall become Vested Shares effective as of the date of such termination, In addition, the Committee shall retain the discretion to accelerate the vesting
of all or part of any Option Shares in the event of Employee’s resignation in the event that the Committee determines, in its sole discretion, that such accelerated vesting is appropriate. Any Option Shares that do not become Vested Shares in
accordance with the preceding provisions of this Section 3(a) shall be forfeited to the Company for no consideration as of the date of the termination of the Employee’s employment with the Company. 

(b) The Option shall in all events terminate at the close of business on the tenth
(10th) anniversary of the Date of Grant (the “Expiration Date”). Subject to the relevant provisions and limitations contained herein and in the Plan, the Employee may
exercise the Option to purchase all or a portion of the applicable number of Vested Shares at any time prior to the termination of the Option pursuant to this Agreement. Notwithstanding the foregoing, unless otherwise provided for by the Committee,
the Option shall expire and cease to be exercisable with respect to the Vested Shares on the date that is three months after the date of the Employee’s 

  
 -2- 







 
employment with the Company terminates for any reason (if such date is earlier than the Expiration Date). No less than 500 Vested Shares may be purchased at any one time unless the number
purchased is the total number of Vested Shares at that time purchasable under the Option. In no event shall the Employee be entitled to exercise the Option for any Nonvested Shares or for a fraction of a Vested Share. 

(c) Any exercise of the Option by the Employee shall be in writing and addressed to Chief Financial Officer of the Company. Exercise of the
Option shall be made by delivery to the Company by the Employee (or other person entitled to exercise the Option as entitled hereunder) of (i) an executed “Notice of Stock Option Exercise” (in substantially the form attached hereto as
Exhibit A) and (ii) payment of the aggregate Exercise Price for Option Shares purchased pursuant to the exercise. 
 (d) Payment of the
Exercise Price may be made, at the Employee’s election, with the approval of the Company, (i) in cash, by certified or official bank check or by wire transfer of immediately available funds, (ii) by delivery to the Company of a number
of shares of Stock having a Fair Market Value as of the date of exercise equal to the Exercise Price, or (iii) by net issue exercise, pursuant to which the Company will issue to the Employee a number of shares of Stock as to which the Option is
exercised, less a number of shares with a Fair Market Value as of the date of exercise equal to the Exercise Price. 
 (e) If the Employee is
on a leave of absence for any reason, the Company may, in its sole discretion, determine that the Employee is still considered to be in the employ of or providing services for the Company, provided that rights to the Option will be limited to the
extent to which those rights were earned or vested when the leave of absence began. 
 (f) If the Option is intended to be an Incentive Stock
Option, then in the event the Option Shares (and all other options designed pursuant to Section 422 of the Code granted to the Employee by the Company or any parent of the Company or Subsidiary) that first become exercisable in any calendar
year have an aggregate Fair Market Value (determined for each Option Share as of the Date of Grant) that exceeds $100,000, the Option Shares in excess of $100,000 shall be treated as subject to a nonstatutory Option. In addition, if the Option is
intended to be an Incentive Stock Option, during the employee’s lifetime the Option shall be exercisable solely by the employee. 
 4.
Withholding of Tax. To the extent that receipt, vesting or exercise of the Option results in compensation income or wages to the Employee for federal, state, or local tax purposes, the Employee shall deliver to the Company at the time
of such receipt, vesting or exercise, as the case may be, such amount of money as the Company may require to meet its minimum obligation under applicable tax laws or regulations, and if the Employee fails to do so (or if the Employee instructs the
Company to withhold cash or stock to meet such obligation), the Company shall withhold from any cash or stock remuneration (including withholding any shares of the Common Stock to be issued to the Employee under this Agreement) then or thereafter
payable to the Employee any tax required to be withheld by reason of such resulting compensation income or wages. The Company is making no representation or warranty as to the tax consequences to the Employee as a result of the receipt of the
Option, the vesting of the Option, or the exercise of the Option.

 5. No Shareholder Rights. The Option granted pursuant to this Agreement does not
and shall not entitle the Employee to any rights of a holder of Common Stock prior to the date that shares of Common Stock are issued to Employee following exercise of the Option. The Employee’s rights with respect to the Option shall remain
forfeitable at all times prior to the date on which the Option Shares become vested and are exercised in accordance with Section 3. 

6. Clawback. Notwithstanding any provisions in the Agreement to the contrary, any compensation, payments, or benefits provided
hereunder (or profits realized from the sale of the Common Stock delivered hereunder), whether in the form of cash or otherwise, shall be subject to a clawback to the extent necessary to comply with the requirements of any applicable law, including
but not limited to, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, section 304 of the Sarbanes Oxley Act of 2002, or any regulations promulgated thereunder. 

7. Employment Relationship. For purposes of this Agreement, the Employee shall be considered to be in the employment of the
Company as long as the Employee remains an employee of either the Company or a Subsidiary. Without limiting the scope of the preceding sentence, it is specifically provided that the Employee shall be considered to have terminated employment or
service with the Company at the time of the termination of the “Subsidiary” status of the entity or other organization that employs or engages the Employee. Nothing in the adoption of the Plan, nor the award of the Option thereunder
pursuant to this Agreement, shall confer upon the Employee the right to continued employment by or service with the Company or affect in any way the right of the Company to terminate such employment or service at any time. Unless otherwise provided
in a written employment or consulting agreement or by applicable law, the Employee’s employment by or service with the Company shall be on an at-will basis, and the employment or service relationship may be terminated at any time by either the
Employee or the Company for any reason whatsoever, with or without cause or notice. Any question as to whether and when there has been a termination of such employment or service, and the cause of such termination, shall be determined by the
Committee or its delegate, and its determination shall be final. 
 8. Notices. Any notices or other communications provided
for in this Agreement shall be sufficient if in writing. In the case of the Employee, such notices or communications shall be effectively delivered if hand delivered to the Employee at the Employee’s principal place of employment or if sent by
registered or certified mail to the Employee at the last address the Employee has filed with the Company. In the case of the Company, such notices or communications shall be effectively delivered if sent by registered or certified mail to the
Company at its principal executive offices. 
 9. Notice of Sales Upon Disqualifying Disposition of ISO. If the Option is
designated as an Incentive Stock Option in Section 1, the Employee must comply with the provisions of this Section 9. The Employee must promptly notify the Chief Financial Officer of the Company if the Employee disposes of any of the
shares acquired pursuant to the Option within one year after the date the Employee exercises all or part of the Option or within two years after the Date of Grant. Until such time as the Employee disposes of such shares in a manner consistent with
the provisions of this Agreement, unless otherwise expressly authorized 

  
 -4- 







 
by the Company, the Employee must hold all shares acquired pursuant to the Option in the Employee’s name (and not in the name of any nominee) for the one-year period immediately after the
exercise of the Option and the two-year period immediately after the Date of Grant. At any time during the one-year or two-year periods set forth above, the Company may place a legend on any certificate representing shares acquired pursuant to the
Option requesting the transfer agent for the Company’s stock to notify the Company of any such transfers. The Employee’s obligation to notify the Company of any such transfer will continue notwithstanding that a legend has been placed on
the certificate pursuant to the preceding sentence. 
 10. Entire Agreement; Amendment. This Agreement and the documents
incorporated by reference herein replace and merge all previous agreements and discussions relating to the same or similar subject matters between the Employee and the Company and constitute the entire agreement between the Employee and the Company
with respect to the subject matter of this Agreement, except as otherwise provided herein. This Agreement may not be modified in any respect by any verbal statement, representation or agreement made by any employee, officer, or representative of the
Company or by any written agreement unless signed by an officer of the Company who is expressly authorized by the Company to execute such document. 

11. Binding Effect; Survival. This Agreement shall be binding upon and inure to the benefit of any successors to the Company and
all persons lawfully claiming under the Employee. The provisions of Section 6 shall survive the exercise of the Option. 
 12.
Controlling Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to conflicts of law principles thereof, or, if applicable, the laws of the United States.
