Under the terms of the agreement, Siris will acquire all of the outstanding common stock of PGi for $14.00 per share in cash, representing a premium of approximately 23 percent over the closing price on September 10, 2015, and approximately 32 percent over PGi's volume-weighted average share price during the 90 days ended September 10, 2015. The agreement was unanimously approved by PGi's Board of Directors, which recommended that PGi's shareholders approve and adopt the merger agreement with Siris. A special meeting of PGi's shareholders will be held as soon as practicable following the filing of a definitive proxy statement with the U.S. Securities and Exchange Commission ("SEC") and subsequent mailing to shareholders.

PGi may solicit alternative acquisition proposals from third parties during a 45-day "go-shop" period, following the date of execution of the merger agreement. There is no guarantee that this process will result in a superior proposal, and the merger agreement provides Siris with a customary right to match a superior proposal.

"Siris' acquisition of PGi is a strong endorsement of our SaaS transformation strategy and provides immediate value to our shareholders," said Boland Jones, PGi founder, chairman and CEO. "Working with Siris will allow PGi greater flexibility to accelerate our strategy in order to remain a leader in today's highly competitive unified communications and collaboration (UC&C) market."

We are eager to support PGi on its journey while also looking to drive new opportunities for innovation and growth as PGi continues to anticipate the changing needs of its world-class customer base."

The transaction is subject to customary closing conditions, including the receipt of shareholder approval, the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and other foreign antitrust regulatory approvals, as necessary.
