About CoSine Communications

CoSine Communications was founded in 1998 as a global telecommunications equipment supplier to empower service providers to deliver a compelling portfolio of managed, network-based IP and broadband services to consumers and business customers. CoSine's strategic plan is to redeploy its existing resources to identify and acquire new business operations, while continuing to provide support to CoSine's existing customers. CoSine's redeployment strategy will involve the acquisition of one or more operating businesses with existing or prospective taxable earnings. This strategy may allow CoSine to realize future cash flow benefits from its net operating loss carry-forwards ("NOLs"). As of this date, no candidates have been identified, and no assurance can be given that the Company will find suitable candidates, and if it does, that it will be able to utilize its existing NOLs.

Currently, CoSine's business consists primarily of a customer service capability operated under contract by a third party.
