                 VARLEN ENTERS INTO DEFINITIVE AGREEMENT TO BUY
                 BRENCO THROUGH $165 MILLION CASH TENDER OFFER
 
  MERGER WOULD CREATE PREEMINENT RAILROAD EQUIPMENT MANUFACTURER WITHIN VARLEN
 
    NAPERVILLE,  Ill.,  June 17,  1996 --  Varlen Corporation  (NASDAQ:VRLN) and
Brenco, Incorporated (NASDAQ:BREN) of the Richmond, Va. area, today announced  a
definitive  agreement for  Varlen to  buy Brenco in  a $165  million cash tender
offer, creating  within Varlen  a preeminent  global manufacturer  of  precision
engineered  railroad products that  is well-positioned to  capitalize on growing
international interest in American freight railroad technologies.
 
    The merger would  transform Varlen  into a company  with approximately  $500
million  in 1997 annual sales and  3,200 employees with manufacturing facilities
in 13 states, as  well as Germany and  France, and would substantially  increase
railroad  products revenue. The acquisition is anticipated  to add up to 7 cents
per share to fiscal 1996 earnings based on a late July closing.
 
    "Varlen and  Brenco are  a great  strategic fit,"  said Richard  L.  Wellek,
Varlen's  president and chief  executive officer. "Varlen  has enjoyed excellent
long-term growth on  the strength  of our current  businesses. This  combination
will  help us grow faster in our railroad and automotive markets. This continues
our corporate focus on  manufacturing highly-engineered transportation  products
and  analytical instruments, maintaining niche  market leadership, and expanding
our international presence."
 
    Terms of the agreement approved by  both boards of directors include  prompt
commencement,  through a wholly-owned Varlen subsidiary,  of a tender offer at a
price of $16 1/8 for each outstanding  share of Brenco common stock. The  tender
offer  requires that Varlen  will be able  to obtain at  least two-thirds of the
shares at the expiration of the offer, which is scheduled to remain open for  20
business  days. An offer to purchase containing  all of the terms and conditions
will be  mailed to  Brenco shareholders  in  the next  few days.  The  agreement
contemplates  that  shares not  tendered  would be  acquired  at the  same price
through a  merger. Brenco  has approximately  10.2 million  shares  outstanding.
Persons  related to Brenco's founding family  -- including Needham B. Whitfield,
Brenco's chairman, and his sister Anne Whitfield Kenny -- control  approximately
20  percent of the stock and have signed a separate shareholder tender agreement
with Varlen.
 
    "At a premium  of 32% over  the closing  price for Brenco  shares Friday,  I
believe  Varlen's  offer will  be well  received  by Brenco  shareholders," said
Brenco's chairman and chief  executive officer, Needham  B. Whitfield. "We  feel
very  comfortable  entrusting  Brenco's  dedicated  employees  and  position  of
leadership in the railroad bearing market  to a company of Varlen's caliber  and
reputation.  The cultures of the two  companies are extremely compatible. Varlen
understands our markets -- both in the automotive and in the railroad industries
- -- and  supports  our market  strategies  of continual  product  innovation  and
outstanding  customer service. Most important for our future, Varlen is prepared
to invest in our plans for growth."
 
    After the merger, Brenco would continue to be based in the Richmond area and
would become a wholly-owned subsidiary of Varlen. J. Craig Rice would remain  as
Brenco president.

    Varlen  has been  a manufacturer  of railroad  products since  its founding.
Wellek said potential synergies between  the two companies should create  future
growth  opportunities in railroad  equipment. "We will have  a stronger and more
diverse family of products for the railroad industry, as well as the ability  to
leverage greater sales overseas," he said.
 
    Brenco  is  a  leading  manufacturer and  re-conditioner  of  tapered roller
bearings for freight  cars, for both  the domestic and  overseas markets.  Other
Varlen subsidiaries make railcar shock control devices, outlet gates, locomotive
products and track fastening devices.
 
    Varlen,  headquartered in Naperville, Illinois, is a leading manufacturer of
precision engineered transportation products and analytical instruments for  the
railroad,  heavy-duty truck  and trailer,  automotive and  petroleum industries.
Varlen's customers include  Freightliner, PACCAR, General  Motors, Chrysler  and
TTX. The company had 1995 annual sales of $387 million.
