Any person claiming to be aggrieved by a practice concerning age discrimination in employment made unlawful by section four may bring a civil action under this section for damages or injunctive relief, or both, and shall be entitled to a trial by jury on any issue of fact in an action for damages regardless of whether equitable relief is sought by a party in such action. If the court finds for the petitioner, recovery shall be in the amount of actual damages; or up to three, but not less than two, times such amount if the court finds that the act or practice complained of was committed with knowledge, or reason to know, that such act or practice violated the provisions of said section four. The provisions set forth in the first, second and third paragraphs shall be applicable to such complaint or action to the extent that such provisions do not conflict with the provisions set forth in this paragraph.
