Where one partner has paid a premium to another on entering into a partnership for a fixed term, and the partnership is dissolved before the expiration of that term otherwise than by the death of a partner, the Court may order the repayment of the premium, or of such part thereof as it thinks just, having regard to the terms of the partnership contract and to the length of time during which the partnership has continued; unless

(a) the dissolution is in the judgment of the Court, wholly or chiefly due to the misconduct of the partner who paid the premium, or

(b) the partnership has been dissolved by an agreement containing no provision for a return of any part of the premium.
