Gerdin Revocable Trust, and assets having a value equal to the withdrawn securities were contributed to the 2009 Gerdin Heartland Trust in substitution for the withdrawn securities. To the extent that this substitution of assets is deemed to be a purchase, the price reflecting the value for the withdrawn securities is $19.80 per share.

F6 · price: The sale price per share is estimated as of December 16, 2019 and is subject to adjustment. The final sales price per share will be determined pursuant to a valuation performed by an independent financial advisor retained by the reporting person, with such valuation including an evaluation of trading discounts appropriate for large block transactions in equity securities with similar trading characteristics. If the final sales price per share is not $19.80, the reporting person undertakes to amend this Form 4 to provide the final sales price per share as determined by the independent financial advisor.

F3 · ownership.nature: Mr. Gerdin is one of the beneficiaries of the 2009 Gerdin Heartland Trust. Remainder interests were distributed from grantor retained annuity trusts created for the benefit of Mrs. Gerdin to the 2009 Gerdin Heartland Trust. The two other beneficiaries of the 2009 Gerdin Heartland Trust, Mrs. Durr and Mrs. Janssen, also reported the distribution of the remainder interests. Mr. Gerdin, Mrs. Durr, and Mrs. Janssen serve as co-trustees over shares held by the trust. Beneficial ownership is disclaimed with respect to this trust because none of the trustees have the power to vote or dispose shares without consent of the other two trustees.
