| 11. | Are there any restrictions on                                                 
 participation in the Plan by shareholders residing outside the United States? |

Regulations in certain countries
may limit or prohibit participation in services provided under this type of program. Accordingly, in the case of citizens or residents
of a country other than the United States, its territories, and possessions, the Company may determine, in its sole discretion, not to
allow participation because compliance with applicable regulations is not reasonably practicable.

| 12. | Are there special eligibility                        
 or enrollment rules applicable to Company employees? |

Yes, if you are a Middlesex
employee or are an employee of one of the Company’s subsidiaries (which for purposes of the Plan, includes a subsidiary of one
of the Company’s subsidiaries), you have the additional option of purchasing shares through automatic payroll deductions (See Question
20 for details). Employees who participate through the automatic payroll deduction option may open a Plan account simply by completing
a Direct Share Purchase and Enrollment Form and returning it to the Company. Employees defined as “Section 16 Individuals”
under the Middlesex Water Company Insider Trading Policy are not eligible to participate in automatic payroll deductions under the Plan.

investment of less than $25.00 or more than $25,000.00 per calendar quarter will be returned without interest.

 investment?                    |
