(a) Except as otherwise provided, campaign contributions held by a candidate or group may be used only to pay the expenses of the candidate or group, and the campaign expenses incurred by the candidate or group, that reasonably relate to election campaign activities, and in those cases only as authorized by this chapter.

(b) Campaign contributions held by a candidate or group may not be

(1) used to give a personal benefit to the candidate or to another person;

(2) converted to personal income of the candidate;

(3) loaned to a person;

(4) knowingly used to pay more than the fair market value for goods or services purchased for the campaign;

(5) used to pay a criminal fine;

(6) used to pay civil penalties; however, campaign contributions held by a candidate or group may be used to pay a civil penalty assessed under this chapter if authorized by the commission or a court after it first determines that

(B) the candidate, campaign treasurer, and deputy campaign treasurer cooperated in the revelation of the violation and in its immediate correction; or

(7) used to make contributions to another candidate or to a group; however, it is not a violation of this paragraph if, in circumstances in which a candidate or group participates in a shared campaign activity, the candidate or group participating in the activity

(A) uses campaign contributions of the candidate or group for payment of

(i) all of the shared campaign activity expense; or

(ii) more than the candidate's or group's pro rata share of the activity expense; and

(B) receives, within seven days after payment of the expense, complete reimbursement of the amount of campaign contributions used for payments made on behalf of another candidate or group participating in the activity.

(c) A candidate may use up to a total of $1,000 in campaign contributions in a year to pay the cost of

(1) attending, or paying the cost for guests of the candidate to attend, an event or other function sponsored by a political party or subordinate unit of a political party;

(2) membership in a political party, subordinate unit of a political party, or other entity within a political party, or subscription to a publication from a political party; and
