ORBITAL Increases Credit Facility to $450 Million

-- 10-Bank Group Also Extends Maturity to 2017 --

(Dulles, VA 13 December 2012) - Orbital Sciences Corporation (NYSE: ORB) announced today that it completed an amendment to its existing $300 million credit facility providing for a new five-year $150 million senior secured term loan along with an extension of the maturity of the existing senior secured revolving credit facility.  Following the amendment and extension, the credit facility borrowing capacity has been increased to $450 million in the aggregate, consisting of the $150 million term loan and $300 million of revolving loan capacity that will both mature in December 2017.  All other existing material terms and conditions of the credit facility remain substantially the same.  

Proceeds from the term loan will be used to fund the planned retirement of the
company's existing senior subordinated convertible notes and for general corporate purposes.  The credit facility is supported by a syndicate of 10 banks led by Wells Fargo Securities LLC, Citigroup Global Markets, Inc. and Merrill Lynch, Pierce, Fenner and Smith Incorporated as Joint Lead Arrangers and Joint Bookrunners.

"We are pleased to announce the closing of this expanded credit facility with our banks which allows us to improve our capital structure and maintain our strong liquidity position," said Mr. Garrett E. Pierce, Orbital's Vice Chairman and Chief Financial Officer.  "Further, it gives us significant financial flexibility to support the future growth of our business."
