(a) General rule.--The costs and expenses of any proceeding under section 1579 (relating to valuation proceedings generally), including the reasonable compensation and expenses of the appraiser appointed by the court, shall be determined by the court and assessed against the business corporation except that any part of the costs and expenses may be apportioned and assessed as the court deems appropriate against all or some of the dissenters who are parties and whose action in demanding supplemental payment under section 1578 (relating to estimate by dissenter of fair value of shares) the court finds to be dilatory, obdurate, arbitrary, vexatious or in bad faith.
(b) Assessment of counsel fees and expert fees where lack of good faith appears.--Fees and expenses of counsel and of experts for the respective parties may be assessed as the court deems appropriate against the corporation and in favor of any or all dissenters if the corporation failed to comply substantially with the requirements of this subchapter and may be assessed against either the corporation or a dissenter, in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted in bad faith or in a dilatory, obdurate, arbitrary or vexatious manner in respect to the rights provided by this subchapter.
(c) Award of fees for benefits to other dissenters.--If the court finds that the services of counsel for any dissenter were of substantial benefit to other dissenters similarly situated and should not be assessed against the corporation, it may award to those counsel reasonable fees to be paid out of the amounts awarded to the dissenters who were benefited.
