agreed upon time. Upon termination or expiration of this Agreement, if specifically requested by MBRK, DD shall provide originals or copies of such records to MBRK. Section 4 — Costs to Deliver DD Promotion All costs incurred by DD to deploy its services to promote MOXATAG to DD Target Segment Prescribers will be the responsibility of DD, except as provided in Section 6. Section 5 — Up-Front Payment, Deposit and Promotion Fees 5.1. MBRK will pay DD an Up-Front Payment of $50,000 upon execution of this Agreement. 5.2. Additionally, MBRK shall pay a Deposit to DD equal to $100,000 upon the Promotion Commencement Date. Each month the Parties will review the amount of the Deposit and where necessary MBRK will make an additional deposit payment to DD in order to maintain a total Deposit with DD of at least two (2) times the current month's Promotion Fees. For example, if in a month Promotion Fees are $105,000, then MBRK will increase the Deposit to two (2) times $105,000, equal to $210,000. The Parties agree to meet via conference call within five (5) business days of the end of each month to determine the necessary adjustment, if any, to the Deposit. If it is determined that the Deposit must be increased, within ten (10) business days of the date upon which the new Deposit is determined, MBRK shall send to DD the funds necessary to increase the Deposit. Notwithstanding the above, if during years 2 and 3 of this Agreement, in the event MBRK's then current annual form 10-K filed with the SEC does not contain an audit opinion that expresses doubt about MBRK's ability to continue as a going concern, then MBRK's requirement to maintain a Deposit is waived. In all cases the Deposit amount will be used to settle any outstanding amounts due to DD by MBRK at the end of the Agreement or at the time the Deposit requirement is waived. 5.3. Additionally, on or before the last day of each month, DD will invoice MBRK for the Promotion Fees due for the prior month. Such Promotion Fees shall be calculated by: (a) the following formula for the period from the Effective Date through September 30, 2010: For example: if during the month of March 2010 (a) (A) above was 2,000 TRx and (B) above was $36.50 then MBRK would be remit $36,500.00 to DD. OR (b) the following formula for the period from October 1, 2010 through termination of this Agreement: (A) the Actual DD Target Segment MOXATAG TRx for the Promotional Measurement Period multiplied by: (B) the applicable Gross Margin Per TRx multiplied by: (C) 50%. (A) the Actual DD Target Segment MOXATAG TRx Tablets for the Promotional Measurement Period multiplied by: (B) the applicable Gross Margin Per Tablet multiplied by: (C) 50%. For example: if during the month of November 2010: MBRK would remit $89,425.00 to DD: These Promotion Fees represent fair market value payment for such services rendered. The Parties recognize that Promotion Fees are to be settled on a monthly basis which requires the use of an estimated Gross Margin Per Tablet amount until the actual Gross Margin Per Tablet for an applicable quarter can be determined. Accordingly, to facilitate the calculation and settlement of monthly Promotion Fees for periods after September 2010, the Parties agree that the Gross Margin Per Tablet used to settle the monthly Promotion Fees will be that as calculated using the previous calendar quarter's Gross Margin Per Tablet data and current period's Actual DD Target Segment MOXATAG TRx. Such Promotion Fees for the three months in any calendar quarter will be subject to a true-up process which will occur by the 15th of the second month of the following quarter. By way of example, Promotion Fees for each of the months of April, May and June will be settled using the Gross Margin Per Tablet amount that has been calculated for the quarter ended March 31 and will be subject to a true-up process to occur by August 15 with any adjustment to such Promotion Fees being settled between the parties within 15 days thereafter. 5.4 In the event MBRK shall discontinue detailing prescribers in a territory that is not included in the then current DD Target Segment Prescribers set forth in EXHIBIT 1 to this Agreement or any amendments thereto ("New DD Target Segment Prescribers"), the Parties shall negotiate in good faith the Promotion Fee payable to DD should MBRK desire that DD add those New DD
