18 CURRENT CREDIT PICTURE 1 These ratios and measures are not based on generally accepted accounting principles and are not presented as alternatives mea sur es of operating performance or liquidity. Some of these ratios and measures include, among other things, pro forma adjustments for acquisitions, one - time charges, and other items, as defined in the Credit Agreement. They are presented here to demonstrate compliance with the covenants in the Credit Agreement, as non - compliance with such covenants could have a material adverse effect on the Company. 2 Covenant EBITDA is a measure that includes pro forma adjustments for acquisitions, one - time charges, and other items, as defined in the Credit Agreement. 3 Total Senior Leverage is a measure that includes borrowings under the Credit Agreement, outstanding letters of credit, less c ash held in depository accounts, as defined in the Credit Agreement 4 Net Debt is a measure that includes borrowings under the Credit Agreement, the Senior Notes, other outstanding debt and lette rs of credit, less cash held in depository accounts, as defined in the Credit Agreement.

20 DEFINITION OF NON - GAAP MEASURES In addition to its reported results, MDC Partners has included in its earnings release and supplemental management presentati on certain financial results that the Securities and Exchange Commission defines as "non - GAAP financial measures." Management believes that such non - GAAP financial measures, when r ead in conjunction with the Company's reported results, can provide useful supplemental information for investors analyzing period to period comparisons of the Com pan y's results. Such non - GAAP financial measures include the following: Organic Revenue: Organic Revenue: “Organic revenue growth” and “organic revenue decline” refer to the positive or negative results, respective l y, of subtracting both the foreign exchange and acquisition (disposition) components from total revenue growth. The acquisition (disposition) component is calcu lat ed by aggregating prior period revenue for any acquired businesses, less the prior period revenue of any businesses that were disposed of during the current period. The org ani c revenue growth (decline) component reflects the constant currency impact of (a) the change in revenue of the partner firms which the Company has held throughout each of the com parable periods presented, and (b) “non - GAAP acquisitions (dispositions), net”. Non - GAAP acquisitions (dispositions), net consists of (i) for acquisitions during the current year, the revenue effect from such acquisition as if the acquisition had been owned during the equivalent period in the prior year and (ii) for acquisitions during the previous year, th e revenue effect from such acquisitions as if they had been owned during that entire year (or same period as the current reportable period), taking into account their respective pre - acquis ition revenues for the applicable periods, and (iii) for dispositions, the revenue effect from such disposition as if they had been disposed of during the equivalent period in the pr ior year. Net New Business: Estimate of annualized revenue for new wins less annualized revenue for losses incurred in the period. Adjusted EBITDA: Adjusted EBITDA is a non - GAAP measure that represents operating profit (loss) plus depreciation and amortization, stock - based co mpensation, deferred acquisition consideration adjustments, distributions from non - consolidated affiliates, and other items. Covenant EBITDA: Covenant EBITDA is a measure that includes pro forma adjustments for acquisitions, one - time charges, and other items, as defined in the Credit Agreement. We believe that the presentation of Covenant EBITDA is appropriate as it eliminates the effect of certain non - cash and other items not necessarily indicative of a company’s underlying operating performance. In addition, the presentation of Covenant EBITDA provides additional information to investors about th e c alculation of, and compliance with, certain financial covenants in the Credit Agreement. Included in the Company’s earnings release and supplemental management presentation are tables reconciling MDC Partners’ repo rte d results to arrive at certain of these non - GAAP financial measures. We are unable to reconcile our projected 2019 organic revenue growth to the corresponding GAAP measure be cau se we are unable to predict the 2019 impact of foreign exchange due to the unpredictability of future changes in foreign exchange rates and because we are unable to predict th e occurrence or impact of any acquisitions, dispositions, or other potential changes. We are unable to reconcile our projected 2019 Covenant EBITDA to the corresponding GAA P measure because the amount and timing of many future charges that impact these measures (such as amortization of future acquired intangible assets, foreign exchange t ran saction gains or losses, impairment charges, provision or benefit for income taxes, and certain assumptions used in the calculation of deferred acquisition consideration) ar e variable, uncertain, or out of our control and therefore cannot be reasonably predicted without unreasonable effort, if at all. As a result, we are unable to provide reconciliations of these measures. In addition, we believe such reconciliations could imply a degree of precision that might be confusing or misleading to investors. For the same reasons, w e a re unable to address the probable significance of the unavailable information, which could have a potentially unpredictable, and potentially significant, impact on future GAAP fin anc ial results. Note: A reconciliation of non - GAAP to US GAAP reported results has been provided by the Company in the tables included in the earnings release issued on May 7, 2019.
