Letter From CEO on Zayo Group Organizational StructureZayo Group Org Chart (Graphic

John Scarano is a Co-Founder of Zayo Group and has been COO of Zayo Group since inception. In 2008, Zayo began to organize itself into multiple independent business units. As part of this transition, Mr. Scarano assumed the additional title of President of Zayo Bandwidth ('ZB'), which is Zayo's largest, most profitable business unit. As the scope of ZB increased and as the other business units became autonomous, the role of President of Zayo Bandwidth became Mr. Scarano's primary focus. As part of the organizational adjustments, Mr. Scarano's title of Zayo Group COO was modified to become Zayo Bandwidth COO, so his title is now President and COO of Zayo Bandwidth.

Matt Erickson was an original member of Zayo Group and has had many roles since Zayo's inception including strategy, corporate development, product management, and investor relations. In July of 2010, Mr. Erickson was named President of the newly created business unit Zayo Fiber Solutions ('ZFS'). ZFS provides dark fiber services and customer network construction for carriers, content companies, and enterprises in most of Zayo Group's markets.

Glenn Russo joined Zayo Group in 2008 as President of Zayo Enterprise Networks ('ZEN'). A significant part of ZEN's revenue is managed communications services such as CLEC services, hosted VoIP, and web hosting. A new division is being formed under Mr. Russo called Managed Communications Services ('MCS'). Karl Bradford, who has been with Zayo since early 2009, has been named General Manager of MCS.

In September 2009, Zayo Group acquired Fibernet Telecom Group ('Fibernet'). Fibernet was a combination of a bandwidth infrastructure and a colocation services business. In late 2009, Zayo Colocation, Inc. ('zColo') was created to focus on colocation and interconnection services. In June 2010, David Howson joined Zayo as President of zColo.

In November 2007, Zayo Group acquired Onvoy. Approximately 40% of Onvoy's revenue was in wholesale voice services and this led to the creation of a business unit called Onvoy Voice Services ('OVS'). On March 12, 2010, as part of Zayo Group becoming a first time issuer of High Yield Bonds, OVS was spun out of Zayo Group, LLC. Zayo Group Holdings, Inc. owns both Zayo Group, LLC and OVS. Fritz Hendricks, a member of Zayo Group's executive team since the Onvoy acquisition, remained OVS' President. Zayo Group, LLC treats OVS as a related party in its financial reporting.

I believe strategic focus, management empowerment, and financial accountability are essential to creating value for our stakeholders. The business unit structure allows us to maintain focus, empowerment and accountability while prosecuting multiple telecom and Internet infrastructure strategies.'
