Company Announcement

HYPERCUBE, INC. TO MARKET RELEASE 5 OF CLIENT-SERVER VERSIONS OF HYPERCHEM FOR SILICON GRAPHICS

August 23, 1998

Boston, MA (ACS Conference) – Hypercube, Inc. announced that it is updating Release 5 of the client-server products of HyperChem for UNIX platforms from Silicon Graphics. These new releases will supply back ends for molecular mechanics, semi-empirical quantum mechanics and ab initio quantum mechanics calculations for SGI computational servers, while the front end is the PC based HyperChem, Release 5. The back ends will be compatible with SGI IRIX 5.3 or higher.

With the availability of Release 5 of the back ends, a PC running HyperChem can transparently send out computationally intensive tasks to a Silicon Graphics server on the network and then get back the results for further analysis. Thus, the superior visualization of HyperChem on the PC is combined with the speed of a computational UNIX server for even better performance.

The new releases are to be shipped to customers in the fourth quarter of 1998.
