The CD is in a state of decline. UMG will increase revenue through a growing array of new digital business models and products. The Transition to Digital Existing digital business models and products A la carte PC-based audio and video downloads Mastertones and other mobile personalization products Tethered audio subscription services (e.g., Napster) Ad-supported video on demand streaming (e.g., Yahoo!) Emerging digital business models and products OTA audio downloads Ringbacktones and "alert tones" Bundled online and mobile products Portable subscription services Mobile video, incl., MTVMobile and mobile broadcast (MediaFlo, DVB-H) Ad-supported audio services, e.g., Napster and SpiralFrog

UMG's US Mastertone sales have exploded as the US has become the #1 Mastertone market UMG sold over 44m Mastertones in 1H '06 Product Snapshot: US Mastertones 151% Growth

Q2 '06 OTA download revenue grew 17% from prior quarter OTA downloads represented 9% of total UMG global downloads in July, '06 OTA downloads have exceeded expectations in several markets Strong growth in UK and Italy from carrier "3" KDDI has driven the market in Japan Sprint and Verizon leading a strong marketing push in the US Product Snapshot: Mobile OTA downloads

Although iTunes is the dominant player overall, the international market is more fragmented than the US After a slower start, UMG's international online download revenue grew at a faster rate than the US in 1H '06 Product Snapshot: Int'l Online downloads Product Snapshot: Int'l Online downloads Product Snapshot: Int'l Online downloads Product Snapshot: Int'l Online downloads 185% Growth

Music videos: traditionally "promotional" Annual cost to UMG of tens of millions of dollars UMG has led the industry in monetizing our video assets Within 3 years, music videos will evolve from a marketing cost to net source of revenue This represents a major "sea change" in the industry Product Snapshot: Digital Video Content

In markets with minimal existing sales, digital and mobile business models can emerge rapidly (e.g., India, China, Africa, Eastern Europe) Markets lost to piracy can become commercially viable (China, Russia, Mexico) Distribution becomes viable in unwieldy geographic areas (Russia, India, China) particularly with tech savvy and emerging middle class in China and India Emerging Markets UMG has adapted its strategy in less developed markets based on prevailing local conditions.
