Bio-Reference Laboratories Reports First Quarter 1997 Results.

ELMWOOD PARK, N.J.--(BUSINESS WIRE)--March 17, 1997--Bio-Reference Laboratories, Inc. (NASDAQ Small Cap-"BRLI") announced today net income of $26,735 for the first quarter ended January 31, 1997 compared to a loss of $373,022 for the comparable period last year. The Company had net revenues of $9,275,144 which represented a 14% increase over the comparable period. The Company also had gross profit on revenues of $4,470,643, which representeden compared to the previous quarter last year, the Company was disappointed with these results."

Dr. Grodman attributed part of the less than expected level of profitability to the inability to transition a greater number of clients from the customer list obtained from the Company's purchase of SmithKline Beecham's Clinical Laboratoging breach of contract, misrepresentation and fraud with regard to SBCL's sale of its customer list and as governmental agencies jointly announced the civil settlement of charges against SBCL in the amount of $32 claims alleged by the United States in the civ the investigations, and that the actual focus and magnitude of the inquiry caused many of the potential accounts to select other testing laboratories which were not connected with SBCL.

Bio-Reference Laboratories, Inc. is a hinical chemistry, special chemistry, endocrinologis.

Today's News On The Net - Business Wire's full file on0043 MAR 17,1997 5:03 PACIFIC 8: 03 EASTERN p. (NASDAQ:XYLN) today announced a major extensip technology which Xylan developed to implement cell switching is called X-Cell.

Why Multi-Layer Switching?

Campus networking has consolidated on a new modelenter, using simple LAN switches, with ATM upli n -- A high-speed switching fabric in the wiring closet can support Fast Ethernet to every desk. Simple access switches don't have the bandwidth to do this. In manyer switch should combine:

-- LAN (MAC-layeruting to move data between virtual workgroups

In a true multi-layer switch, frames and cells must be linked together with a high-speed SAR (segmentation-and-reassembly) process. The OmniSwitch's FCSM (frame-to-cell switching module) provides both a 622 Mbps SAR function -- rt-VBR (real-time variable bit rate, such as MPEG video) -- nrt-VBR (non-real-time variable bit rate, such as frame relay) -- ABR (available bit rate, such as PCs and other workstations with ATM interface cards) -- UBR (unspecified bit rate, such as LAN switches)

Revolutionary Buffer Management

The OmniSwitch ATM cell switching pioneers the use of DIBOC (Dynamic Input Buffering with Output Control). Xylan is patenting this technique, which makes optimal use of buffers, and allows the fabric to support large loads without cell loss, even in bursty, mixed-traffic applications. DIBOC also makes large cell buffers economically feasible. The OmniSwitch supports:

-- 1,365 cell buffers per 25M port (expandable to 4,096) -- 8,192 cell buffers per OC-3c/STM-1 port (expandable to 32,768) -- 131,072 cell buffers per OC-12c/STM-4c port -- over 2,000,000 cell buffers per OmniSwitch

Older ons, which will continue to transmit until a lae cell buffers, to sustain the load. And when even those are not enough, it will still outperform other switches due to intelligent cell discard mechanisms:

-- Witions, with 16 levels of priority, so that in the event that cells must be lost, high-priority channels are the ATM backbone is the most critical part ofne interconnects the modules at wire speed, so t second. Access switches using redundant UNI raffic. And this is truly dynamic PNNI. CDV (cell delay variation) and maxCTD (maximum cell transit delay)rapidly as a switch can set up virtual circuit connection s. The fast call setup time of the OmniSwitch minim standards.

-- ATM Forum UNI 3.0 & 3.1 -- ATM Forum PNNI 1.0 -- ATM Forum IISP (for interoperability with older ATM switches) -- LAN Emulation 1.0, client and server, Ethernet and Token Ring -- Traffic Management 4.0 -- IAB RFC 1483 (ATM LAN Encapsulation) -- IAB RFC 1577 (Classical IP over ATM) -- SVCC (switched virtual channel connections), both point-to-point

and multipoint

SVPC (switched virtual path connections), both point-to-point lities include:

-- redundant LANE services:(for example, 100 ELANs with 50 clients each) -- intelligent broadcast management: the OmniMSS Broadcast Manager scans broadcast frames, such as IP ARP requests and replies, and transforms broadcast frames to unicast frames, dramatiit to serve as an effective wiring closet alternative to "Superhubs." At the same time, the OmniSwitch X- -- 16 OC-12 ports, multimode and single mode fan's network management tools. Extensive port acou nters; that's enoug h to count cells for three minutes on an OC-3 link. The OmniSwitch uses 40-bit counters -- enough for 35 days.

New Generation of Chip Technoxtensive virtual circuit statistics, fabric muur years since its founding, Xylan Corp. has introduced a complete set of technologies for high-bandwidth cale now and in the next six months include:

d 25M ports, using advanced buffer management - policy-based virtual LANs -- the broadest in the networking industry -- IP security firewall software, tightly coupled with the switching fabric -- compressed, high-speed frame relay for wide area access -- graphical network management, with unique tools for managing VLAN policies and members, ATM virtual circuits, network-wide traffic patterns, and hardware/software configuration

Many of the capabilities described in this release are available in OmniSwitch release 3.0, shipping in March. Some capabilities will become available in the second quarter of 1997. This news release includes forward-looking statements that involve risks and uncertainties, including the timely availability of new products and other risks detailed in the company's prospectus and report Form 10-Q for the quarte4
