Altura Software, Inc. Acquires WinSock SDK for Mac OS from NetManage, Inc.

PACIFIC GROVE, Calif. — April 21, 1997 — Altura Software, Inc. announced
today that it has acquired the WinSock SDK for Mac OS from NetManage, Inc.
(NASDAQ: NETM) for an undisclosed amount. WinSock SDK for Mac OS provides a
single network API common to both Windows and Mac OS making it easier to
port TCP/IP applications to the Mac OS environment.

WinSock SDK for Mac OS is the only WinSock API for the Mac OS platform.
Bridging the TCP/IP network API gap between the Windows and Mac OS
platforms, WinSock SDK for Mac OS gives developers a tool for porting their
WinSock based applications from Windows to the Mac OS platform.
Additionally, it gives developers a single API for writing applications to
the two stack technologies currently available on the Mac OS platform –
Open Transport and MacTCP.

WinSock SDK for Mac OS is an ideal tool for developers who have been tasked
with porting their applications to the Mac OS or are developing concurrent
projects for both Windows and Mac OS. Because Apple’s upcoming Mac OS
Rhapsody will most likely be sockets based, the WinSock SDK will give
developers a great head start. The SDK offers both 68K and PowerPC support.
The libraries can be used with the most popular Mac OS development

Altura is actively in the process of determining new features for the
WinSock SDK and has not yet announced pricing and support details.
Customers with interest in the SDK or questions are asked to contact Altura
directly or through their web site (

to port to the Macintosh. Most recently, Altura acquired Object Master, a
cross platform programming tool. The WinSock SDK for Mac OS makes a perfect

the cross platform developer.
