Certain audited historical financial statements of the Company for the fiscal years ended December 31, 2008 through December 31, 2010;

The unaudited financial statements of the Company for the nine months periods ended September 30, 2010 and September 30, 2011;

Certain internal business, operating and financial information and forecasts for the fiscal years ended December 31, 2011 through December 31, 2016 (the “Forecasts”), prepared by the senior management of the Company;

Financial terms of certain other transactions we deemed relevant and whose information is publicly available;

Key Assumptions Underlying Our Review and Analysis

Executive Summary

We have held discussions with members of the senior management of the Company to discuss certain of the foregoing.

We have considered other matters which we have deemed relevant to our inquiry and have taken into account such accepted financial and investment banking procedures and considerations as we have deemed relevant.

We have assumed and relied, without independent verification, upon the accuracy and completeness of all the information examined by or otherwise reviewed or discussed with us for purposes of this opinion, including, without limitation, the Forecasts, and we do not assume any responsibility or liability therefore.

We relied on the information furnished by the Company (and information available from public sources and other sources deemed reliable by Blair) without assuming any duty of independent verification thereof.

We have not made or obtained an independent valuation or appraisal of the assets, liabilities or solvency of the Company before or after giving effect to the Merger, nor have any such valuation or appraisals been provided to us.

We express no opinion with respect to the Forecasts or the estimates and judgments on which they are based.

We express no opinion as to any terms or other aspects of the Merger, including, without limitation, the form or structure of the Merger, or accounting consequences thereof.

We did not consider and express no opinion as to the amount or nature of any compensation to any of the officers, directors or employees of any party to the Merger, or class of such persons, relative to the compensation to any other party.

We were not asked to consider, and our opinion does not address, the relative merits of the Merger as compared to any alternative business strategies that might exist for the Company or the effect of any other transaction in which the Company might engage.

Our opinion herein is based upon economic, market, financial and other conditions existing on, and other information disclosed to us as of, the date hereof. It should be understood that, although subsequent developments may affect this opinion, we do not have any obligation to update, revise or reaffirm this opinion.

Discounted Cash Flow Analysis

Discounted Cash Flow Analysis

Parameters

Performed a discounted cash flow analysis of MELODY’s standalone projected results to calculate the present value of MELODY based on its future earnings stream and corresponding cash flows

Utilized MELODY management’s projections for FY 2011E through FY 2016E

Estimated the value of MELODY at the end of FY 2016E (“terminal value”) utilizing multiples of projected FY 2016E EBITDA ranging from 5.0x to 7.0x

A 11% to 15% discount rate range was selected based upon a weighted average cost of capital analysis of selected public companies and was used to calculate a present value of FY 2011E –FY 2016E cash flows and the terminal value as of November 30, 2011

The aggregate present value of these items represents the enterprise value range. An equity value range was determined by deducting net debt at September 30, 2011

A range of per share prices was determined by dividing the derived equity value by the total diluted shares outstanding at each respective value, including in-the-money options

($ in millions, except per share amounts)
