Debtor's Actions on Collateral Note. Prior to the occurrence of an Event of Default, Debtor may take such actions as it may reasonably deem necessary to enforce performance by MHM under the Collateral Note in accordance with the terms thereof; but in no event shall Debtor, without the prior written consent of Secured Party, compromise or settle any action or otherwise agree to accept any amount less than an amount equal to one hundred percent (100%) of the outstanding unpaid principal balance of the Collateral Note, together with all accrued and unpaid interest thereon, in full and final satisfaction of MHM's obligations under the Collateral Note. Additionally, Debtor hereby expressly agrees that any proceeds that represent principal of the Collateral Note which result from any such enforcement action by Debtor shall be deemed to be a prepayment of principal on the Collateral Note, subject to all the terms and provisions of paragraph 12 above, and the direction to MHM by Debtor in accordance with the terms of paragraph 12 shall also include a direction that the proceeds of any enforcement action shall be treated the same as the prepayment of principal. If an Event of Default shall occur and be continuing, the Debtor shall not accelerate the maturity of the Collateral Note or take any affirmative collection actions without the prior written consent of the Secured Party, which consent may be withheld in the Secured Party's sole discretion. In the event the Secured Party consents to the sale of any collateral securing the Collateral Note such sale shall be for cash (and such cash proceeds shall be immediately paid to Secured Party), and the Debtor may not bid a credit against the Collateral Note without the prior or contemporaneous written consent of the Secured Party, which consent may, but need not, set a maximum amount which may be so credited. 14. Receipt of Principal by Debtor. In the event that, notwithstanding the terms of this Collateral Transfer of Note, Debtor receives any payments of principal or proceeds that represent principal of the Collateral Note which result from any enforcement action with respect -5- 6 to the Collateral Note, the Debtor shall be deemed to hold the same in trust for Secured Party and shall immediately forward such payments to the designated escrow agent or, unless, prior to or contemporaneously with Debtor's receipt of the same, Substitute Collateral satisfactory to Secured Party, in its reasonable discretion, with respect to which all matters necessary to create a first priority security interest in favor of Secured Party have been completed, to Secured Party in accordance with the terms hereof. 15.
