Try this RegExp:

^[A-Z][a-zA-Z]{2}(?=.*[0-9!])(?=.*\p{P}).{4,7}

 

<asp:RegularExpressionValidator ID="regexpName" runat="server"   
                  ErrorMessage="This expression does not validate." 
                  ControlToValidate="txtName"   
                  ValidationExpression="^[A-Z][a-zA-Z]{2}(?=.*[0-9!])(?=.*\p{P}).{4,7}
