§ 342-c. Tolling of the period of limitations by proceedings of the
United States. Whenever any civil or criminal proceeding is instituted
by the federal government to prevent, restrain, or punish violations of
the federal antitrust laws, the running of the period of limitations in
respect of every right of action arising under sections three hundred
forty, three hundred forty-two and three hundred forty-two-a of this
article, based in whole or in part on any matter complained of in the
federal proceeding, shall be suspended during the pendency of said
proceeding and for one year thereafter; provided, however, that whenever
the running of the period of limitations in respect of a right of action
arising under sections three hundred forty, three hundred forty-two or
three hundred forty-two-a of this article is suspended hereunder, any
action to enforce such right of action shall be forever barred unless
commenced either within the period of suspension or within the period of
limitations otherwise prescribed in this article.
