    CLARENCE, N.Y. & MINNEAPOLIS--(BUSINESS WIRE)--April 30,
2007--Greatbatch, Inc. (the "Company") (NYSE:GB) and Enpath Medical,
Inc. (Nasdaq:NPTH) announced today that they have entered into a
definitive merger agreement under which Greatbatch will acquire Enpath
for $14.38 per share in cash, or approximately $102 million, including
assumption of debt. Under the terms of the agreement, Greatbatch will
commence a tender offer for all of Enpath's outstanding shares no
later than May 8, 2007.

    The proposed transaction is subject to customary closing
conditions and regulatory approvals and the tender of a majority of
Enpath's outstanding shares, on a fully diluted basis. The purchase
price will be funded out of Greatbatch's available cash and the
transaction is not subject to financing conditions. The transaction is
expected to close in late June and has been unanimously approved by
the Boards of Directors of both companies.

    Based in Minneapolis, Enpath is a medical products company engaged
in designing, developing, manufacturing and marketing single use
medical device products for the cardiac rhythm management ("CRM"),
neuromodulation and interventional radiology markets.

    Enpath's main product lines consist of the following:

    --  Venous vessel introducers and valved introducers that enable
        physicians to create a conduit through which they can insert
        infusion catheters, implantable ports and pacemaker leads into
        a blood vessel.

    --  Advanced delivery catheters that can be manipulated to enable
        the health care professional to access parts of the patient's
        anatomy that cannot be reached by traditional introducers.

    --  Implantable stimulation leads, adaptors and delivery systems
        for the cardiac and neuromodulation markets.

    Thomas Hook, Greatbatch President and CEO stated, "Enpath
represents an exciting strategic opportunity that is complementary and
further expands our product and service offerings to the CRM and
Neurostimulation marketplace. This acquisition broadens our market
reach into the vascular segment with the core introducer product line
as well as adding several major new OEM customers. Clearly these
factors support our long-term objective of customer and market
diversification. We welcome the employees of Enpath to the Greatbatch
team and look forward to working with them and their strong management
team."

together we believe we can accelerate the delivery of new product
offerings to our customers. Greatbatch's financial strength provides
incremental funding for our product development pipeline initiatives.
