ITEM 2. TENDER OFFER OF THE BIDDER.
 
    This statement relates to the tender offer by Varlen Corporation, a Delaware
corporation ("Varlen") and  its wholly-owned subsidiary,  BAS, Inc., a  Virginia
corporation (the "Purchaser"), disclosed in a Tender Offer Statement on Schedule
14D-1,  dated  June 20,  1996 (the  "Schedule  14D-1"), to  purchase all  of the
outstanding shares (the "Shares") of Common  Stock at $16.125 per share, net  to
the  seller in  cash, without any  interest, upon  the terms and  subject to the
conditions set forth in the Offer to  Purchase, dated June 20, 1996 (the  "Offer
to  Purchase"),  and  the  related  Letter  of  Transmittal  (collectively,  the
"Offer"), copies of which are filed herewith as Exhibits A and B,  respectively,
and incorporated herein by reference.

June 15, 1996 (the  "Acquisition Agreement"), by and  among the Company,  Varlen
and  the  Purchaser,  a  copy  of  which is  filed  herewith  as  Exhibit  C and
incorporated herein by reference, and  a Shareholder Tender Agreement, dated  as

Time"),  each share of Common Stock then  outstanding (other than shares held by
Varlen, the Purchaser,  or any other  subsidiary of Varlen,  and shares held  by
shareholders  who exercise their dissenters' rights,  if any, in accordance with
the Virginia Stock Corporation Act (the  "Virginia Act") will be converted  into
the right to receive $16.125 in cash, without any interest.
 
    Based  on  information in  the Offer  to  Purchase, the  principal executive
offices of Varlen and the Purchaser are located at 55 Shuman Boulevard, P.O. Box
3089, Naperville, Illinois 60566-7089, telephone (708) 420-0400.
 
ITEM 3. IDENTITY AND BACKGROUND.
 
    (A) NAME AND ADDRESS OF  THE COMPANY. The name  and address of the  Company,
which  is the person  filing this Statement, is  set forth in  Item 1 above. All
information contained  in this  Statement or  incorporated herein  by  reference
concerning  the Purchaser, Varlen or their affiliates, or actions or events with
respect to any of them, was  provided by the Purchaser or Varlen,  respectively,
and the Company takes no responsibility for such information.
 
    (B)  MATERIAL CONTRACTS. Each material  contract, agreement, arrangement and
understanding or actual or  potential conflict of  interest between the  Company
and/or  its affiliates and  (i) its executive  officers, directors or affiliates
and (ii) Varlen, its executive  officers, directors or affiliates, is  described
below.
 
        (B) (1) CERTAIN CONTRACTS. Effective March 22, 1996, the Company entered
into  change in control agreements (the "Agreements") with Needham B. Whitfield,
J. Craig Rice, Jacob M. Feichtner, Howard J. Bush and Donald E. Fitzsimmons (the
executive officers named in the Company's proxy statement for the Annual Meeting
of Shareholders)  and certain  other executives  and employees.  The  Agreements
provide that termination compensation will be paid if the executive's employment
is  terminated by the Company  within two years after  a Change in Control other
than for "cause"  (as defined in  the Agreements) or  upon the death,  permanent
disability  or  retirement of  the executive,  or  if the  executive voluntarily
terminates his  employment for  "good reason"  (as defined  in the  Agreements).
Change  in Control is defined generally to  include (i) acquisition of more than
20% of the Company's  voting stock, (ii) certain  changes in the composition  of
its Board of Directors,

(iii)  shareholder approval of  certain business combinations  or asset sales in
which the Company's historic shareholders hold less than 50% of the resulting or
purchasing  company  or  (iv)  shareholder   approval  of  the  liquidation   or
dissolution  of the Company. Termination compensation consists of a cash payment
equal to a multiple (generally  one, two or three  times) of the highest  annual
rate  of base  salary paid to  the executive  in effect for  the 12-month period
immediately prior to the executive's termination of employment ("Base  Salary").
The  multiple is  one times Base  Salary for Messrs.  Whitfield and Fitzsimmons,
three times Base Salary for  Mr. Rice, two times Base  Salary for Mr. Bush,  and
the number of years from date of termination to age 62 times Base Salary for Mr.
Feichtner  (who is  now age  59). In  addition, the  Agreements provide  for the
continuation of certain  medical, life and  disability benefits. The  Agreements
supersede employment agreements between the Company and certain executives which
were previously in place.
 
    The  Company's Executive Retirement Incentive  Plan, as amended and restated
effective March 22, 1996 (the  "Executive Plan"), provides a monthly  retirement
benefit  for  life  to  those  executives  selected  for  participation  by  the
Compensation Committee of the Board of Directors  equal to the excess of (i)  3%
of  the executive's  remuneration multiplied  by his years  of service  (up to a
maximum of 20 years), over (ii) the  value of benefits payable to the  executive
by  the company  retirement plan  and the  executive's Social  Security benefit.
Messrs.  Whitfield,  Rice,  Feichtner,  Bush  and  Fitzsimmons  are  among   the
executives  participating in the  Executive Plan. In order  to receive a benefit
under the Executive Plan, the executive must have at least five years of vesting
service and must retire after attaining age  55 but no later than the first  day
of  the calendar quarter coinciding with or next following his attaining age 62.
The Executive  Plan  provides  for  benefit  payment  options  and  spousal  and
beneficiary  rights  and payments  in  the event  of  the executive's  death. No
benefits are payable under  the Executive Plan to  any executive who  terminates
employment  before attaining age 55 or who  does not retire during the available
retirement window period.  In addition,  benefits under the  Executive Plan  are
forfeited  if  a  retired  executive competes  with  the  Company  under certain
circumstances.
 
    The Company  has  established a  grantor  trust to  accumulate  the  amounts
anticipated to be needed to pay benefits under the Executive Plan. Assets of the
trust  are considered general assets of the Company and are subject to claims of
the Company's creditors. The Company is  obligated to make contributions to  the
trust  annually in an amount equal to  its reported annual financial expense for
the Executive Plan, as adjusted for trust earnings and expenses. In addition, in
the event there  is a  Change in  Control (as  defined in  the Agreements),  the
Company  is obligated to contribute an amount  to the trust within 90 days equal
to the Executive Plan's unfunded actuarial liability at that time.
 
    The Executive  Plan  provides  additional benefits  for  Messrs.  Feichtner,
Fitzsimmons,  and Rice  in the event  there is  a Change in  Control. First, the
Executive Plan may not  be amended to cause  Messrs. Feichtner, Fitzsimmons,  or
Rice  to cease  to be participants.  Secondly, if Mr.  Feichtner's employment is
terminated within two years after  the Change in Control  and on or before  June
30, 1999, by the Company without cause or by Mr. Feichtner for good reason, then
his  benefit  under the  Executive  Plan will  be  calculated as  though  he had
continued to work to  June 30, 1999,  and his benefit  under the Executive  Plan
will  not be reduced for early payment before  age 62 and will include an amount
equal to the amount of any reduction to his benefit under the Company retirement
plan for early payment. Thirdly, if either Messrs. Fitzsimmons or Rice ceases to
be employed before age  62 (including before age  55), respectively, he will  be
fully  vested in his benefit under the Executive Plan, he may start drawing that
benefit at age 55 or his later termination, his beneficiary will be entitled  to
his  death benefit regardless  of his vesting service  or his termination before
age 55, and the prohibition on competition with the Company will be waived if he
resigns for good reason (other than the right to voluntarily terminate during  a
30 day period after the first anniversary of the Change in Control). As of March
8,  1996, the ages  of each such  executive officer were  as follows: Needham B.
Whitfield - 59, J. Craig Rice - 48, Jacob M. Feichtner - 58, Howard J. Bush - 42
and Donald E. Fitzsimmons - 54.
 
    The Company's estimate  of the  total amount of  all payments  which may  be
payable  upon a Change in Control under the Agreements and the Executive Plan is
$3,435,000.
 
                                       2

    The Company also provides long-term incentive compensation for executives of
the Company (and other Company employees) through the grant of stock options and
restricted stock under the Company's 1988  Stock Option Plan (the "Stock  Option
Plan")  and  1987 Restricted  Stock Plan  (the  "Restricted Stock  Plan"). Stock
options under the  Stock Option Plan  are granted to  executive officers at  the
fair  market  value of  the Common  Stock  on the  date of  grant. Historically,
options have typically been  granted with a five-year  period of exercise and  a
three-year  vesting schedule. However, options granted after July 1994 have been
granted with a ten-year  period of exercise and  are fully exercisable one  year
after the date of grant. Shares of restricted stock granted under the Restricted
Stock  Plan typically  vest over a  four-year period.  As of June  14, 1996, the
Company had outstanding: (1) options to purchase 442,000 shares of Common  Stock
heretofore  granted under the  Company's 1988 Stock  Option Plan ("Options") and
like number of shares reserved for  issuance upon the exercise thereof, and  (2)
62,576  shares  of  Common Stock  heretofore  granted under  the  Company's 1987
Restricted Stock Plan ("Restricted Shares"). Effective March 22, 1996, the Stock
Option Plan  and the  Restricted Stock  Plan were  amended to  provide that  the
events which would constitute a "change in control" under such plans will be the
same  as  the  events which  would  constitute  a Change  in  Control  under the
Agreements. Thus, upon a Change in Control, outstanding Options would be  freely
exercisable and any restrictions on Restricted Shares would lapse.
 
    Under  the Acquisition Agreement, the Company will, to the extent necessary,
adjust the terms of all outstanding Options and all Restricted Shares to provide
for (a)  cancellation of  the Options,  not later  than immediately  before  the
Effective  Time in  exchange for cash  payment equal  to the product  of (i) the
total number of Shares  subject to the  Option and (ii) the  excess, if any,  of
$16.125  (or any such higher price  per Share as may be  paid in the Offer) over
the exercise  price per  Share subject  to such  Option; and  (b)  cancellation,
effective  as  of  the  Effective Time,  of  each  Restricted  Share outstanding
immediately prior to the Merger in exchange  for a payment equal to the  product
of  (i) the  total number  of Restricted  Shares and  (ii) $16.125  (or any such
higher price per Share as may be paid in the Offer).
 
    (B)(2) THE ACQUISITION AGREEMENT AND  THE SHAREHOLDER TENDER AGREEMENT.  The
following  is a summary  of certain provisions of  the Acquisition Agreement and
the Shareholder Tender Agreement and is  qualified in its entirety by  reference
to  the Acquisition  Agreement and the  Shareholder Tender  Agreement, copies of
which are filed herewith as Exhibits C and D, respectively.
 
    THE ACQUISITION AGREEMENT.
 
    THE OFFER AND  MERGER.  The  Acquisition Agreement provides  for the  public
announcement  of the Offer  within one business day  after the execution thereof
and for the  commencement of the  Offer as  promptly as practicable,  but in  no
event  later  than  five  business days,  after  such  public  announcement. The
obligation and right of Purchaser to accept  for payment and pay for any  Shares
tendered  pursuant  to  the Offer  is  subject  to satisfaction  of  the Minimum
Condition (as defined in the Offer  to Purchase), the expiration or  termination
of  all waiting  periods under  the HSR Act  and the  other conditions described
below under "Certain Conditions." The Purchaser expressly reserves the right  to
waive  any such condition, to increase the  price per Share payable in the Offer
and to make any other changes in the terms and conditions of the Offer; provided
that the Purchaser has agreed that it will not (i) decrease the price payable in
the Offer, (ii) change  the form of  consideration payable in  the Offer or  the
Merger,  (iii) increase the Minimum  Condition, or (iv) amend  any other term of
the Offer (including the conditions described under "Certain Conditions"  below)
in a manner materially adverse to the holders of Shares.
 
    The  Acquisition Agreement provides  that, as soon  as practicable following
consummation of the Offer and the satisfaction or waiver of certain  conditions,
the  Purchaser will be merged  into the Company, with  the Company surviving the
Merger. Pursuant to the Merger, each  outstanding Share (other than Shares  held
by  Varlen, the Purchaser, or any direct or indirect subsidiary of Varlen or the
Purchaser, and  Shares  with  respect  to which  dissenter's  rights  under  the
Virginia Act are properly exercised) will be converted into the right to receive
$16.125 in cash, without any interest. Following
 
                                       3

the  Merger, the Company will be a wholly owned subsidiary of Varlen. The Merger
is subject to the satisfaction of various conditions, including approval by  the
Company's shareholders if required under the Virginia Act.
 
    In  the Acquisition Agreement the Company has represented and warranted that
its Board of  Directors has approved  the Offer and  the Merger and  recommended
acceptance of the Offer by holders of Shares and approval of the Merger (if such
approval  is required by the Virginia Act) by holders of Shares. The Company has
further represented and warranted that its Board of Directors (all of whom,  the
Company's counsel has opined to Varlen, are "disinterested directors" within the
meaning  of the Virginia Act with respect to Varlen and the Purchaser) has taken
certain actions  in order  to  exempt Varlen,  the Purchaser,  their  respective
direct  and  indirect  subsidiaries and  the  Offer,  the Merger  and  the other
transactions contemplated by the Acquisition Agreement from the restrictions and
other provisions of: (A)  Article 14 (AFFILIATED  TRANSACTIONS) of the  Virginia
Act,  in the manner  provided by Section 13.1-727.B.1(iv)  which (absent such an
exemption   or   similar    board   action)    generally   prohibits    mergers,
recapitalizations,  share exchanges, asset sales  and other transactions between
certain Virginia  corporations  and holders  of  10%  or more  of  their  voting
securities   ("interested  shareholders")  unless  approved  by  a  majority  of
"disinterested directors"  and/or holders  of  two-thirds of  the  corporation's
shares  excluding those of the interested shareholder; (B) Article 14.1 (CONTROL
SHARE ACQUISITIONS) of  the Virginia  Act, which  (absent such  an exemption  or
similar board action) generally denies voting rights to certain acquirers of 20%
of  more  of  the outstanding  voting  power  of a  public  Virginia corporation
("acquiring persons") unless  granted by a  majority of the  shares entitled  to
vote  in the election of  directors of the corporation  other than those held by
acquiring persons  and certain  corporate insiders;  and (C)  Article I  of  the
Articles  of Incorporation,  as amended  of the  Company (the  "Charter"), which
(absent such  an  exemption or  similar  board action)  generally  requires  the
affirmative  vote of holders of 75% of the  Shares in order to approve a merger,
consolidation and certain other business combinations between the Company and  a
beneficial  owner of  10% or more  of its Shares.  The Company and  its Board of
Directors have agreed to take such other actions necessary or appropriate at the
request of Varlen or the Purchaser  to: (1) exempt Varlen, the Purchaser,  their
respective direct and indirect subsidiaries, the Offer, the Merger and the other
transactions  contemplated by the  Acquisition Agreement from  the provisions of
any takeover,  affiliated  transactions,  business  combination,  control  share
acquisition  or other provision of (i) law  or regulation of the Commonwealth of
Virginia or any department or  agency thereof or (ii)  the Charter or Bylaws  of
the  Company,  and (2)  maintain the  shareholder vote  required to  approve the
Merger at the two-thirds level.
 
    COVENANTS OF THE COMPANY.  Under the Acquisition Agreement, the Company  has
agreed  that, except as Previously Disclosed (as hereinafter defined) and unless
Varlen or the Purchaser otherwise agree in writing, prior to the Effective  Time
or  such earlier time as designees of the Purchaser constitute a majority of the
Board of Directors of the Company:

officers,  employees,  investment  bankers,  representatives  or  agents  shall,
directly or indirectly, make, solicit, initiate or encourage the initiation  of,
any  inquiries or  proposals from,  or provide  any confidential  information or
participate in any discussions or  negotiations with, or otherwise cooperate  in
any  way with  or assist,  any person (other  than Varlen  and its subsidiaries,
those third parties  previously disclosed in  writing by the  Company to  Varlen
prior to the execution of the Acquisition Agreement ("Previously Disclosed") and
their  respective directors, officers, employees, investment bankers, commercial
banks, representatives and agents)  concerning any merger, consolidation,  other
business  combination,  recapitalization,  liquidation  or  dissolution  or  any
purchase or other acquisition or sale or other disposition of assets (other than
in the ordinary course of business) or shares of capital stock of the Company or
any of its  subsidiaries or  any similar  transaction involving  the Company  or
(except  as Previously Disclosed)  any subsidiary or division  of the Company or
any subsidiary;  PROVIDED,  HOWEVER,  that  (i) the  Company  or  its  Board  of
Directors  shall not be  prohibited from taking and  disclosing to the Company's
shareholders a position  contemplated by  Rule 14d-9 or  Rule 14e-2  promulgated
under  the Exchange Act, and (ii) in the event that the Company shall receive an
unsolicited proposal from a third party  which the Company's Board of  Directors
determines,  based on the advice of  its legal counsel and independent financial
advisor, is capable of  consummating such transaction,  for the acquisition  for
cash  of  all  the outstanding  Shares  on  terms that  the  Company's  Board of
Directors determines, based on the advice of its financial advisor (the  receipt
of   which   advice  shall   be   confirmed  in   writing   to  Varlen   by  the
 
                                       5

Company), are economically  superior to those  of the Offer  and the Merger  and
which  in the written opinion  of legal counsel to  the Company (the delivery of
which shall be  confirmed in writing  to Varlen  by such counsel)  a failure  to
consider  by the Board  of Directors of  the Company would  create a substantial
risk of  violating  their fiduciary  duties  to shareholders,  the  Company  may
provide information to such third party to the same extent that such information
has  been provided to the Purchaser and Varlen. The Company must promptly advise
Varlen of, and communicate to Varlen the terms of, any such inquiry or  proposal
the Company may receive.
 
    CONFIDENTIALITY AND STANDSTILL AGREEMENTS.  Under the Acquisition Agreement,
the  Company  has  agreed  to  use  its  reasonable  best  efforts  to  obtain a
confidential information, non-disclosure, non-use and standstill agreement  from
any  third party with  or for whom the  Company or any  subsidiary has taken any
action or  received  any  proposal not  prohibited  under  the  non-solicitation
provisions  of the Acquisition Agreement. The Company also agreed not to consent
to the termination or amendment of the confidential information,  non-disclosure
or  non-use provisions  of any  agreement with a  third party  without the prior
written consent  of Varlen  or the  Purchaser, and  to use  its reasonable  best
efforts  to take  all actions necessary  or proper to  enforce strict compliance
with such provisions.
 
    STOCK INCENTIVE  PLANS.   Under the  Acquisition Agreement,  the Company  is
required  to  adjust the  terms  of all  outstanding  employee stock  options to
purchase Shares  granted under  any stock  option plan  of the  Company and  all
restricted Shares granted under any restricted stock plan to cancel such options
and restricted shares. Not later than immediately prior to the Merger, each such
option  and restricted Share shall become  fully exercisable or unrestricted, as
the case may be, and vested. The  Company has agreed to use its reasonable  best
efforts  to cancel each  option outstanding not later  than immediately prior to
the Merger in exchange for a cash payment equal to the product of (i) the  total
number  of Shares subject to the option and  (ii) the excess, if any, of $16.125
(or any such  higher price  per Share  as may  be paid  in the  Offer) over  the
exercise  price per Share subject to such option. The Company has also agreed to
use its reasonable best efforts to cancel each restricted Share outstanding  not
later than immediately prior to the Merger in exchange for $16.125. In addition,
the Board of Directors has agreed to take appropriate action with respect to the
Company's  Employee Stock Savings Plan (the "Savings Plan") to provide that: (i)
until the earlier  to occur  of the  Effective Time  or any  termination of  the
Acquisition  Agreement, participants in the Savings Plan will not be eligible to
receive matching Shares on any Shares  purchased by such participants after  the
date  the  Acquisition Agreement,  and (ii)  any rights  of participants  in the
Savings Plan to receive matching Shares from  the Company as of the date of  the
Acquisition  Agreement accrued as a result of Shares purchased prior to the date
of the Acquisition Agreement shall be  cancelled in exchange for a payment,  not
later than immediately prior to the Effective Time, from the Company (subject to
any  applicable withholding taxes) in cash equal to the product of (x) the total
number of such accrued  matching Shares and (y)  $16.125. Under the  Acquisition
Agreement,  any other  plan providing  for the  issuance or  grant of  any other
interest in respect of the capital stock of the Company or any subsidiary  shall
terminate as of the consummation of the Merger.
 
    DESIGNATION OF DIRECTORS.  The Acquisition Agreement provides that, promptly
upon  the acceptance for payment  of and payment by  the Purchaser in accordance
with the  Offer  for  Shares  constituting  50%  or  more  of  all  Shares  then
outstanding  in accordance with the Offer, and from time to time thereafter, the
Purchaser will be entitled to designate such number of directors, rounded up  to
the next whole number, on the Board of Directors of the Company as will give the
Purchaser representation on the Board of Directors equal to at least that number
of  directors which equals the  product of the total  number of directors on the
Board of Directors multiplied  by the percentage that  such number of Shares  so
accepted  for payment and paid for or owned  by Varlen or the Purchaser bears to
the total number of  Shares outstanding; PROVIDED,  HOWEVER, that the  Purchaser
shall have the right (in its discretion) to designate a number of directors less
than such product; AND PROVIDED FURTHER, HOWEVER, that at all times prior to the
Merger  there shall  be at least  two members of  the Board of  Directors of the
Company selected by  current members  of such  Board. Subject  to the  preceding
sentence, upon the Purchaser's purchase of the Shares pursuant to the Offer, the
Purchaser will have sufficient voting
 
                                       6

power to remove the entire Board of Directors of the Company and replace it with
the  Purchaser's nominees. In the Acquisition  Agreement, the Company has agreed
to take all action necessary to cause the Purchaser's designees to be elected to
the Company's  Board of  Directors (including  mailing to  the shareholders  the
information  required  by  Section 14(f)  of  the  Exchange Act  and  Rule 14f-1
promulgated thereunder) and  to use  its reasonable  best efforts  to cause  the
resignation  of  such  directors, and/  or  an  increase in  the  number  of its
directors, as may be directed by Varlen and required to implement the foregoing.
 
    SHAREHOLDERS MEETING.  The Merger is subject to the satisfaction of  various
conditions,  including, among other things, approval  by the shareholders of the
Company if required under the Virginia Act. If the Purchaser acquires the number
of Shares required to satisfy the Minimum Condition, it will control  two-thirds
of  the outstanding Shares on a  fully diluted basis. Accordingly, the Purchaser
would have  sufficient  voting power  to  approve the  Merger  at a  meeting  of
shareholders  to vote thereon. In the event that as a result of the Offer Varlen
owns 90% or more of  the outstanding Shares, the  Purchaser and Varlen would  be
able  to effect the Merger  pursuant to the short  form merger provisions of the
Virginia Act without  any action by  any other shareholder  of the Company,  but
subject  to the requirements of the Virginia  Act that a copy of the Acquisition
Agreement be mailed  to shareholders  and to the  applicable dissenter's  rights
provisions of the Virginia Act.
 
    In connection with the Merger, the Company has agreed that it shall take all
action  necessary,  in accordance  with  the Virginia  Act  and its  charter and
bylaws, to convene a meeting of  its shareholders as promptly as practicable  to
consider and vote upon the Merger (if and to the extent required by the Virginia
Act),  and to not take any action which  would result in the affirmative vote of
shareholders required for approval of the  Merger to be greater than  two-thirds
of the votes entitled to be cast. Unless in the written opinion of legal counsel
to the Company (the delivery of which shall be confirmed in writing to Varlen by
such  counsel) any of the  following actions would create  a substantial risk of
violating the fiduciary duties of the Board of Directors to the shareholders  of
the  Company, the  Company has  also agreed: (i)  that the  proxy or information
statement with respect  to any meeting  of the Company's  shareholders or  other
corporate  action to  approve the  Acquisition Agreement  and the  Merger, shall
contain the recommendation of  the Board of Directors  that the shareholders  of
the  Company vote to adopt and approve the Merger and the Acquisition Agreement,
and (ii) if proxies are solicited, to use its reasonable best efforts to solicit
from its shareholders proxies in favor of such adoption and approval and to take
all other action necessary or, in the reasonable judgment of Varlen, helpful  to
secure  the vote  or consent  of shareholders  required by  the Virginia  Act to
effect the Merger. At such meeting  of the shareholders of the Company,  Varlen,
the  Purchaser and their direct  and indirect subsidiaries will  vote all of the
Shares then owned by any of them in favor of the Merger.
 
    CONFIDENTIALITY.  Under the Acquisition Agreement, Varlen and the  Purchaser
have   agreed  to,   and  to  cause   their  officers,   employees,  agents  and
representatives to, keep confidential, unless compelled to disclose by  judicial
or  administrative  process or  by other  requirements  of law,  all non-public,
confidential or proprietary information provided  by the Company (except to  the
extent  that such information can be shown  to have been (i) previously known by
Varlen or the Purchaser, (ii) in the public domain through no fault of Varlen or
the Purchaser, or (iii)  later lawfully acquired by  Varlen from other  sources)
and will not release or disclose such information to any other person.
 
    INDEMNIFICATION  AND INSURANCE.  The Acquisition Agreement provides that the
Charter or Bylaws of the Company, after the Merger (the "Surviving Corporation")
shall contain provisions no less favorable with respect to indemnification  than
those  that are set forth in the Company's Charter and Bylaws, as amended to the
date the Acquisition Agreement, which provisions may not be amended, repealed or
otherwise modified for a period  of five years after  the Effective Time in  any
manner  that would adversely affect the  rights thereunder of individuals who on
or prior to the Effective Time were directors, officers, employees or agents  of
the  Company  (the  "Indemnified  Parties"). Varlen  shall  cause  the Surviving
Corporation to fulfill such indemnification  obligations. Varlen also agreed  to
use  its reasonable best efforts  to cause to be  maintained in effect for three
years from the Effective Time the current policy (or successor policies) of  the
directors' and officers' liability insurance maintained
 
                                       7

by the Company with respect to matters occurring prior to the Effective Time, to
the  extent available; PROVIDED, HOWEVER, that  Varlen is not required to expend
more than an amount per  year equal to 150% of  current annual premiums paid  by
the Company to maintain or procure insurance coverage pursuant hereto.
 
    REPRESENTATIONS  AND WARRANTIES.  The Acquisition Agreement contains various
customary representations  and  warranties  of the  parties  thereto,  including
representations  by  Varlen  and  the Purchaser  as  to  their  organization and
qualification, authority  relative  to the  Acquisition  Agreement,  compliance,
financing,  and brokers and finders,  and by the Company  as to its organization
and qualification, capitalization, capitalization of its subsidiaries, authority
relative to the Acquisition Agreement, lack of conflicts, filing of reports  and
financial  statements,  litigation, employee  benefit  plans, taxes,  absence of
certain changes, brokers and finders, liabilities, contracts, board actions, and
cash and cash equivalents.
 
    TERMINATION.  The Acquisition Agreement may be terminated at any time  prior
to the Effective Time, whether prior to or after approval by the shareholders of
the Company:
 
           (A)
           by  mutual written consent  of the Boards of  Directors of Varlen and
           the Company;
 
           (B)
           by  either  the  Company  or   Varlen  if  any  court  of   competent
           jurisdiction  or other governmental body  shall have issued an order,
    decree or ruling or taken any  other action (which order, decree, ruling  or
    other  action the parties hereto shall  use their reasonable best efforts to
    lift),  in  each  case,  permanently  restraining,  enjoining  or  otherwise
    prohibiting  the Offer or the Merger and such order, decree, ruling or other
    action shall have become final and non-appealable;
 
           (C)
           by the Company, if the Offer shall have been terminated, or the Offer
           shall have expired,  without the  purchase of  any Shares  thereunder
    within  two business days thereof and  such non-purchase shall not have been
    due to a failure to satisfy any of the conditions of the Offer described  in
    Section  13 of  this Offer  to Purchase; PROVIDED  that the  Company may not
    terminate the Acquisition  Agreement if  the Company  is in  breach of  such
    agreement;
 
           (D)
           by  the Company, if the Effective Time  shall not have occurred on or
           before December 31, 1996 due to a failure of any of the conditions to
    the obligations of  the Company  to effect the  Merger as  described in  the
    Acquisition  Agreement;  PROVIDED that  the  Company may  not  terminate the
    Agreement if  the Company's  failure  to fulfill  any obligation  under  the
    Acquisition  Agreement has been the cause of, or resulted in, in whole or in
    part, the failure of the Effective Time to occur on or before such date;
 
           (E)
           by the Company, if: (1)  any corporation, partnership, person,  other
           entity  or group (as defined in Section 13(d)(3) of the Exchange Act)
    other than Varlen or the Purchaser  or any of their respective  subsidiaries
    or  affiliates  (a  "Qualified  Person") shall  have  commenced  (within the
    meaning of Rule 14d-2 under  the Exchange Act) a  cash tender offer for  any
    and  all Shares at a price at or in  excess of $16.125 per Share, or (2) any
    Qualified Person shall have  made a bona fide  written proposal involving  a
    merger  or consolidation of the Company or the acquisition of all the Shares
    or all or a substantial portion of  its assets which would result in a  cash
    distribution  to shareholders of the Company  in excess of $16.125 per Share
    (any such proposal described in subclause (1) or (2) being referred to as  a
    "Qualified  Proposal"), and the Board of Directors of the Company shall have
    been advised in a writing by its legal counsel (the delivery of which advice
    shall have been confirmed in writing  to Varlen by such counsel) that  there
    would  be  a substantial  risk of  liability for  breach of  their fiduciary
    obligations to shareholders if they failed to recommend such offer or accept
    such Qualified  Proposal;  PROVIDED,  HOWEVER,  that  the  Company  may  not
    terminate  the  Acquisition  Agreement:  (i) until  the  expiration  of five
    business days after notice of such Qualified Proposal has been delivered  to
    Varlen,  or (ii) unless otherwise consented to  in writing by Varlen, if any
    such offer or Qualified Proposal is made in  breach of, or as a result of  a
    breach of its non-solicitation obligation described herein;
 
                                       8

           (F)
           by  either of Varlen or the Purchaser, if due to a failure to satisfy
           any of the conditions  of the Offer described  in Section 13 of  this
    Offer to Purchase: (i) Varlen or any of its subsidiaries or affiliates shall
    not  have commenced the Offer,  or shall have terminated  the Offer, or (ii)
    the Offer shall have expired without  the purchase of any Shares  thereunder
    within  two business days thereof, or (iii) Varlen shall have determined not
    to proceed with the Merger; PROVIDED  that neither Varlen nor the  Purchaser
    may terminate the Acquisition Agreement if either Varlen or the Purchaser is
    in material breach of such agreement;
 
           (G)
           by either of Varlen or the Purchaser, if the Effective Time shall not
           have  occurred on or before December 31, 1996 due to a failure of any
    of the conditions to the obligations  of Varlen and the Purchaser to  effect
    the  Merger described  in the  Acquisition Agreement;  PROVIDED that neither
    Varlen nor the Purchaser may terminate the Acquisition Agreement if Varlen's
    or the  Purchaser's failure  to fulfill  any material  obligation under  the
    Acquisition  Agreement has been the cause of, or resulted in, in whole or in
    part, the failure of the Effective Time to occur on or before such date; or
 
           (H)
           by either of  Varlen or the  Purchaser, if prior  to the purchase  of
           Shares  in the  Offer, the  Board of  Directors of  the Company shall
    have: (1)  withdrawn, or  modified in  a  manner adverse  to Varlen  or  the
    Purchaser,  its approval or recommendation of the Offer or the Merger or any
    of its  other  actions  taken  in accordance  with  the  provisions  of  the
    Acquisition  Agreement summarized in the third paragraph of "The Acquisition
    Agreement -- The Offer and Merger" hereinabove, (2) taken any of the actions
    referred to in  the third  paragraph of  "The Acquisition  Agreement --  The
    Offer  and Merger"  hereinabove for  the benefit  of any  person (other than
    Varlen, the  Purchaser  or any  of  their respective  subsidiaries)  or  any
    transaction  (other than the Offer and Merger), or (3) resolved to do any of
    the foregoing.
 
    TERMINATION FEE.  If the Acquisition Agreement is terminated by the  Company
pursuant to the provision described in clause (E) of  "The Acquisition Agreement
- --  Termination"  above or  if  the Acquisition  Agreement  and/or the  Offer is
terminated by Varlen or the Purchaser by reason of a failure of any condition to
the Offer described in (i) paragraphs (a),  (b) or (g) as set forth below  under
"Certain  Conditions,"  (ii) paragraph  (c) as  set  forth below  under "Certain
Conditions," (but only  if due,  in whole  or in  part, to  any (x)  act of  the
Company  or  any affiliate  thereof,  or (y)  other  occurrence, event,  fact or
circumstance not beyond the control of the Company or any affiliate thereof), or
(iii)  clause  (vi)  of  paragraph  (c)  as  set  forth  below  under   "Certain
Conditions,"  the  Company has  agreed to  pay  to Varlen  a termination  fee of
$6,500,000 plus an amount  sufficient to reimburse  Varlen and its  subsidiaries
for  all fees, costs  and expenses relating to  the transactions contemplated by
the  Acquisition  Agreement,  the  financing  contemplated  by  the  Acquisition
Agreement  and the transactions contemplated  thereby (PROVIDED that the Company
shall not be  obligated to reimburse  Varlen or its  subsidiaries for more  than
$2,000,000 of such fees, costs and expenses).
 
    In the event of the termination of the Acquisition Agreement, it will become
null and void and have no effect without any liability on the part of any party,
except  that provisions relating to the termination fee, expenses of the parties
and confidentiality  of  information  will  survive  any  such  termination  and
provided  that a party will not be relieved from liability for any breach of the
Acquisition Agreement.
 
    COSTS AND  EXPENSES.   The  Acquisition Agreement  provides that  except  as
provided  above  under "Termination  Fee," all  costs  and expenses  incurred in
connection with the transactions contemplated by the Acquisition Agreement shall
be paid by the party incurring such costs and expenses.
 
    DISSENTER'S RIGHTS.  No dissenter's rights are available in connection  with
the Offer. Holders of Shares may be entitled to dissenter's rights in connection
with  the Merger if, at the record date with respect to the meeting at which the
Acquisition Agreement and the  Merger will be  acted upon, certain  requirements
are satisfied.
 
    Section  13.1-730  of the  Virginia  Act (as  effective  from July  1, 1996)
provides that no dissenter's rights are available for the shares of any class or
series of stock which, at the record date fixed to
 
                                       9

determine the shareholders  entitled to  receive notice of  and to  vote at  the
meeting of shareholders to act upon the agreement or plan of merger, were either
(i)  listed on a national securities exchange  or on the National Association of
Securities Dealers Automated Quotation System or (ii) held of record by at least
2,000 shareholders, unless, among other things,  in either case (i) the  holders
of such class or series of shares are required by the terms of such agreement or
plan  to accept for such shares anything  except cash or (ii) the transaction to
be voted on  is an  "affiliated transaction"  that has  not been  approved by  a
majority of "disinterested directors." See Section 15.
 
    If the conditions of Section 13.1-730 of the Virginia Act are not met and if
the  Merger or  a similar  business combination  is consummated,  the holders of
Shares not purchased pursuant to the Offer would have certain rights to  dissent
and  demand to be paid the "fair value"  of their Shares under the Virginia Act.
Under the  Virginia  Act, dissenting  shareholders  who comply  with  applicable
statutory  procedures would be  entitled to payment  of the "fair  value" of the
Shares as  to which  dissenter's rights  are  properly claimed  as of  the  time
immediately before the effectuation of the Merger (excluding any appreciation or
depreciation  in  anticipation of  the Merger,  unless  such exclusion  would be
inequitable). In the first instance, the "fair value" estimation is made by  the
corporation.  Dissatisfied dissenters may  then notify the  corporation of their
own "fair value" estimation. If the corporation and the dissatisfied shareholder
cannot settle on the amount owed, the shareholder will ultimately be entitled to
a judicial determination of "fair value." Any such judicial determination of the
"fair value" of the Shares could be  based upon considerations other than or  in
addition  to the  price paid in  the Offer and  the market value  of the Shares,
including asset  values,  the investment  value  of  the Shares  and  any  other
valuation  considerations generally  accepted in  the investment  community. The
"fair value" of the Shares  so determined could be more  or less than the  price
per Share to be paid pursuant to the Offer and the Merger.
 
    THE  FOREGOING SUMMARY  OF THE  RIGHTS OF  DISSENTING SHAREHOLDERS  DOES NOT
PURPORT TO  BE COMPLETE.  THE EXERCISE  AND PRESERVATION  OF DISSENTER'S  RIGHTS
REQUIRE STRICT ADHERENCE TO THE APPLICABLE PROVISIONS OF THE VIRGINIA ACT.
 
    SHAREHOLDER TENDER AGREEMENT.
 
    SUMMARY.    Simultaneously  with entering  into  the  Acquisition Agreement,
Varlen entered  into a  Shareholder Tender  Agreement (the  "Shareholder  Tender
Agreement")   with  certain   shareholders  of   the  Company   (the  "Tendering
Shareholders"), including  Needham B.  Whitfield, Chairman  and Chief  Executive
Officer of the Company, Anne Whitfield Kenny (whose husband, John C. Kenny, is a
director  of the Company),  and certain members  (and trusts for  the benefit of
members) of their families. Pursuant  to the Shareholder Tender Agreement,  each
Tendering  Shareholder has agreed to tender pursuant to the Offer and before the
Expiration Date  all of  the Shares  owned  of record  or beneficially  by  such
Tendering  Shareholder on the date of the Shareholder Tender Agreement, together
with any  Shares  acquired  by  any such  Tendering  Shareholder  prior  to  the
termination  of the  Shareholder Tender  Agreement. As  of the  date hereof, the
Tendering Shareholders beneficially own 2,108,343 Shares, or approximately 20.7%
of all outstanding Shares.
 
    The Shareholder Tender  Agreement provides that  each Tendering  Shareholder
will tender its Shares pursuant to the Offer before the Expiration Date and will
not  withdraw any  Shares so  tendered without  Varlen's prior  written consent;
PROVIDED, HOWEVER,  that each  Tendering Shareholder  may: (i)  refrain from  so
tendering its Shares, and may withdraw any Shares previously so tendered, if and
for  so long as there shall have been commenced and not terminated a cash tender
offer by any person  or "group" (other  than Varlen or the  Purchaser or any  of
their  respective subsidiaries or affiliates) for any  and all Shares at a price
in excess of $16.125 per share (a "Superior Offer"); and (ii) tender its  Shares
pursuant  to such  Superior Offer;  AND PROVIDED  FURTHER, HOWEVER,  that in the
event that (x)  any such Superior  Offer shall have  expired or been  terminated
without purchase of such Tendering Shareholder's Shares, and (y) the Offer shall
then be in effect, then such Tendering Shareholder shall again be subject to the
foregoing provisions.
 
                                       10

    Notwithstanding  the foregoing, the Shareholder  Tender Agreement permits up
to 50,000  of  the Tendering  Shareholders'  Shares  (in the  aggregate)  to  be
contributed to one or more charitable organizations and, if and to the extent so
contributed,  such Shares will  not be required  to be tendered  pursuant to the
Offer.
 
    OTHER AGREEMENTS.  During the term of the Shareholder Tender Agreement,  and
except  as  otherwise provided  therein  or with  the  prior written  consent of
Varlen, each Tendering Shareholder may not (i) sell, pledge or otherwise dispose
of any of its Shares, (ii) deposit its Shares into a voting trust or enter  into
a  voting agreement or arrangement with respect  to such Shares, (iii) grant any
proxy, power-of-attorney  or other  authorization  in or  with respect  to  such
Shares,  or  (iv)  enter  into  any contract,  option  or  other  arrangement or
undertaking with respect to the direct or indirect sale, assignment, transfer or
other disposition of such Shares.
 
    The Shareholder  Tender Agreement  requires  each Tendering  Shareholder  to
abide  by  the  terms  of the  non-solicitation  provisions  of  the Acquisition
Agreement summarized in "The Acquisition Agreement -- Non-Solicitation"  section
set forth above in this Section 11.
 
    TERMINATION.    The Shareholder  Tender  Agreement will  terminate  upon the
earlier to occur of: (i) the termination of the Acquisition Agreement (if  any),
and (ii) the Effective Date.
 
CERTAIN CONDITIONS.
 
    Notwithstanding  any  other provision  of the  Acquisition Agreement  or the
Offer, and  except as  expressly  limited below,  the  Purchaser: shall  not  be
required  to commence or continue the Offer;  or accept for payment, purchase or
pay for  any Shares  tendered;  may postpone  the  acceptance for  payment,  the
purchase  of,  and/or payment  for,  Shares; and/or  may  amend (subject  to the
restrictions  contained  in  Section  1.1  of  the  Acquisition  Agreement,)  or
terminate  the Offer; if: (1) there shall not have been validly tendered and not
withdrawn prior  to  the expiration  of  the Offer  a  number of  Shares  which,
together  with  the  Shares  beneficially owned  by  the  Purchaser  and Varlen,
represents two-thirds of the total voting  power of all shares of capital  stock
of  the Company outstanding on a fully  diluted basis, or (2) any waiting period
under the Hart-Scott-Rodino Antitrust Improvement Act of 1976, as amended  ("HSR
Act"),  applicable to the purchase of the Shares pursuant to the Offer shall not
have expired or been terminated,  or (3) at any time  on or after June 1,  1996,
and  prior to the time of payment for any such Shares (whether or not any Shares
have theretofore been accepted for payment  or paid for pursuant to the  Offer),
any  of the  following events  (each, an "Event")  shall have  occurred (each of
paragraphs (a) through (h) providing a separate and independent condition to the
Purchaser's obligations pursuant to the Offer):
 
    (a)the Company shall have authorized, recommended or proposed, or shall have
       announced an intention to authorize, recommend or propose, or shall  have
entered into an agreement or agreement in principle with respect to, any merger,

dissolution, or any purchase or other  acquisition or sale or other  disposition
of  assets (other than in the ordinary  course of business) or shares of capital
stock of the  Company or  any of its  Subsidiaries, or  any similar  transaction
involving  the  Company or  any Subsidiary  or  division of  the Company  or any
Subsidiary (other than the  Merger and as Previously  Disclosed with respect  to
certain  subsidiaries)  (the  foregoing  being  collectively  referred  to  as a
"Business Combination"),  any  material change  in  its capitalization,  or  any
release  or relinquishment of any  material contract or other  rights not in the
ordinary course of business; or

which,  in the sole judgment of the  Purchaser, in any such case, and regardless
of the circumstances  (including any  action or  inaction by  the Purchaser  and
Varlen)  giving rise to any such condition,  make it inadvisable to proceed with
acceptance for payment or purchase of or  payment for any Shares tendered or  to
proceed with the Merger.

action or inaction by Varlen or the Purchaser, or may be waived by Varlen or the
Purchaser in whole  at any  time or  in part  from time  to time  in their  sole
discretion.  The failure by Varlen or the  Purchaser at any time to exercise any
of the foregoing rights shall not be deemed a waiver of any such right and  each
such  right shall be deemed an ongoing right and may be asserted at any time and
from time to time. Any determination  by Varlen or the Purchaser concerning  any
Event shall be final and binding upon all parties.
 
    In  addition, under the Acquisition Agreement  the obligations of Varlen and
the Purchaser to consummate and effect  the Merger are subject to the  condition
that  the Company shall not have received  demands for payment of the fair value
of Shares (pursuant to Article 15 (Dissenter's Rights) of the Virginia Act) with
respect to more than 5% of the outstanding Shares.
 
    In addition, notwithstanding  anything to  the contrary  in the  Acquisition
Agreement,  the obligations of the Purchaser  to accept for payment, purchase or
pay for  any  Shares  tendered  shall  also be  subject  to  the  expiration  or
termination  of all waiting periods under the HSR Act that are applicable to the
purchase of Shares pursuant to the Offer and the Acquisition Agreement.
 
ITEM 4. THE SOLICITATION OR RECOMMENDATION
 
    (A)  RECOMMENDATION  OF  THE  BOARD.   The  Company's  Board  of   Directors
unanimously  has determined that the Offer and the Merger are fair to and in the
best interests  of the  shareholders of  the Company,  has approved  the  Merger
Agreement,  the Offer and the Merger and recommends that all shareholders of the
Company accept the Offer and tender all of their Shares pursuant to the Offer.
 
    (B) BACKGROUND; REASONS FOR BOARD'S RECOMMENDATION.
 
    On December 11, 1995,  at Varlen's request, two  senior officers of  Varlen,
Richard  L. Wellek, President and Chief  Executive Officer, and Raymond A. Jean,
Executive Vice  President and  Chief Operating  Officer, visited  the  Company's
facilities  in Petersburg, Virginia and met  with Needham B. Whitfield, Chairman
of the  Board  of  the Company  and  Chief  Executive Officer,  J.  Craig  Rice,
President   and   Chief   Operating   Officer,   and   Howard   J.   Bush,  Vice
President--Marketing. After a presentation by
 
                                       13

Mr. Bush of  the Company's markets  and businesses, the  Varlen executives  were
given  a  tour  of  the  manufacturing  facilities,  and  afterwards  a  general
discussion ensued. The Varlen executives pointed to a variety of changes in  the
railroad  markets domestically  and internationally,  and proposed  that a large
supplier, with a wide variety of products important to the rail industry,  would
be  better  positioned  to  deal  with  these  changing  conditions.  The Varlen
executives asked  the Company  if they  would be  interested in  combining  with
Varlen  to form such a supplier. The  Company's executives agreed to think about
the proposition, and to have further discussions with Varlen.
 
    At its regular monthly meeting on December 15, 1995, the Company's Board  of
Directors was advised of the Varlen visit and its interest.
 
    On  January 25, 1996, Mr. Wellek,  together with George W. Hoffman, Railroad
Group Vice President for Varlen, returned to Petersburg and resumed  discussions
with  Messrs. Whitfield,  Rice, and Bush.  A number of  marketing synergies were
identified between the two  companies, and both parties  agreed to explore  each
other's operations in greater depth.
 
    At  its regular monthly meeting on January  26, 1996, the Company's Board of
Directors was advised of the Varlen visit and its continuing interest.
 
    On February  20, 1996,  Messrs  Whitfield, Rice  and Bush  visited  Keystone
Industries,  Inc.  in Camp  Hill, Pennsylvania.  Keystone  is a  manufacturer of
railroad equipment components and a wholly  owned subsidiary of Varlen. After  a
tour  of  the  facilities,  further discussions  about  operations  and railroad
markets were conducted with Messrs. Wellek and Hoffman.
 
    On February 21, 1996, Messrs. Whitfield  and Rice accompanied Mr. Wellek  to
Vassar,  Michigan to tour two automotive parts plants of a Varlen subsidiary and
meet local  managers  of  these  operations.  Business  philosophies,  marketing
strategies, organizational culture and operating methods were discussed.
 
    On  March 11,  1996, Mr.  Wellek visited Messrs.  Whitfield and  Rice at the
Company's administrative headquarters in Midlothian, Virginia to discuss whether
there was  enough  fit between  the  two companies  to  explore in  earnest  the
possibility  of a  business combination.  The two  companies agreed  to continue
discussions.
 
    On March 20,  1996, Messrs.  Wellek and  Jean met  Mr. Rice  and Keith  Poe,
Executive  Vice  President of  Quality  Bearing Service  ("QBS"),  the Company's
wholly owned reconditioning subsidiary, in  Little Rock, Arkansas to tour  QBS's
newest reconditioning plant and discuss the reconditioning operations.
 
    On March 21, 1996, Messrs. Wellek and Jean, who were in Louisville, Kentucky
for  an annual truck  show, made a  brief tour of  QBS's reconditioning plant in
Louisville.
 
    At its regular  monthly meeting on  March 22, 1996,  the Company's Board  of
Directors  was advised of  the continuing Varlen  visits and discussions between
the two companies, and the process  the Company intended to follow with  respect
to these discussions was discussed in more detail.
 
    On  March  27,  1996, Varlen  signed  a confidentiality  agreement  with the
Company providing for the transfer  of confidential information to Varlen  about
the  Company's operations and financial results, and holding Varlen subject to a
standstill provision in  the event  Varlen wished  to use  this information  for
purposes of, among other things, making a public tender for the Company shares.
 
    On  April 3, 1996,  Richard A. Nunemaker, Vice  President, Finance and Chief
Financial Officer  of  Varlen,  met  with Jacob  M.  Feichtner,  Executive  Vice
President  and  Chief Financial  Officer  of the  Company  and Mr.  Whitfield to
determine what  financial and  operating data  was available  and to  begin  his
inquiries.
 
                                       14

    On  April  10, 1996,  Messrs. Wellek,  Jean,  Hoffman, Thomas  Robinson, and
others visited the Company's facilities in Petersburg to conduct an  engineering
review  of  the Company's  new  bearing developments  and  its development  of a
one-way clutch for the automotive market. Mr. Rice and several of the  Company's
engineers were involved in the discussions.
 
    On  April  11, 1996,  Messrs. Wellek,  Jean, Hoffman  and Robinson  met with
Messrs. Rice, Whitfield, and James W.  Benz, President of Rail Link, a  contract
switching subsidiary wholly owned by the Company. A variety of railroad industry
and international sales issues were discussed.
 
    On  April 15,  1996, Vicki L.  Casmere, Vice President,  General Counsel and
Secretary of Varlen, met with the  Company's counsel in Richmond and later  with
Messrs.  Feichtner and  Whitfield in Midlothian  to conduct a  general review of
legal matters related to the Company's operations.
 
    At its regular  monthly meeting on  April 18, 1996,  the Company's Board  of
Directors  was brought  up to  date on  the discussions  with Varlen.  The Board
determined that the Company would require the services of a financial advisor to
guide the Board and express an opinion on fairness of whatever consideration and
terms were offered.
 
    On May  7, 1996,  Mr. Wellek  met with  Messrs. Whitfield  and Rice  at  the
Company's Midlothian headquarters to review the status of Varlen's inquiries and
to  advise the Company's  executives that Varlen wished  to acquire the Company,
assuming the contract terms, timing and price were satisfactory to both parties.
There was a  general discussion as  to how  this process might  proceed and  Mr.
Wellek indicated the possible price range of a Varlen offer.
 
    A  Special Meeting of the Company's Board of Directors was called on May 13,
1996. The details of the meeting with Mr. Wellek were reported to the Board, who
determined to engage  the investment  banking firm of  Wheat, First  Securities,
Inc.  ("Wheat")  of Richmond,  Virginia  to serve  as  financial advisor  to the
Company.
 
    Wheat immediately proceeded to conduct a preliminary evaluation of potential
price ranges of comparable and hypothetical transactions. At the Company Board's
regular monthly meeting on  May 24, 1996, the  Company's senior management  made
presentations  on the markets and prospects for the Company's various businesses
and why a  combination with Varlen  would be  in the strategic  interest of  the
company.   This  was  followed  by   Wheat's  presentation  of  its  preliminary
evaluation. Based on the discussions  that followed, the Board directed  Messrs.
Whitfield and Rice to pursue serious negotiations with Varlen as to price, terms
and how such a combination might be effected.
 
    On  May 29, 1996, Messrs. Whitfield and  Rice met with Messrs. Wellek, Jean,
Nunemaker, Robinson  and Ms.  Casmere at  Varlen's headquarters  in  Naperville,
Illinois  Mr.  Whitfield  reported  the  Company  Board's  response  to Varlen's
proposal and asked for definitive terms.
 
    On May  31, 1996,  Mr. Wellek  called Mr.  Whitfield and  informed him  that
Varlen  wished  to make  a cash  tender offer  for the  Shares and  assuming the
Company would cooperate by entering into an acquisition agreement, Varlen  would
submit  a proposed draft of  the agreement. Mr. Wellek  indicated that the final
price offered would depend on the terms of the agreement.
 
    On June  11, 1996,  Mr. Wellek  and  Ms. Casmere  of Varlen,  together  with
Varlen's outside counsel, met with Messrs. Whitfield and Rice of the Company and
its  counsel, and negotiated the basic terms subject to approval of both boards.
Negotiations continued  over the  period  from June  11  to June  14  concerning
certain additional terms.
 
    On  June 13, 1996, the Varlen Board  of Directors met and approved the terms
of the offer  and the  agreements between  the two  companies. Mr.  Bush of  the
Company  was in attendance at the beginning  of the meeting, made a presentation
on the Company's railroad bearing markets  and answered questions by the  Varlen
directors.
 
    At a Special Meeting on June 15, 1996, the Company's Board of Directors met.
Wheat  advised  the  board,  based  on  various  analyses  and  subject  to  the
limitations set forth in its written opinion, that the
 
                                       15

consideration was fair to the Company's  shareholders from a financial point  of
view,  and the Board,  after discussion, approved  the Acquisition Agreement and
agreed to recommend Varlen's offer to the Company's shareholders.
 
    During  the  process  of  its  discussions  with  Varlen,  the  Company  had
conversations  with several other parties who  expressed some degree of interest
in a business combination. A confidentiality agreement was entered into with one
party and information shared. However, no proposals were made by any other party
and based  on the  timing and  substance of  the Varlen  offer and  advice  from
management  concerning the  nature of  discussions that  had occurred  with such
parties  and  from  its  advisor  that  the  company  was  unlikely  to  receive
substantially  higher offers,  the Company's Board  decided to  proceed with the
Varlen negotiations and enter into an agreement recommending the Varlen offer.
 
    The negotiations culminated in the  execution of the Acquisition  Agreement,
and the Shareholder Tender Agreement on Saturday, June 15, 1996. On Monday, June
17,  1996,  Varlen and  the Company,  in  a joint  press release,  announced its
intention to commence the Offer.
 
                                   * * * * *
 
    In approving  the Acquisition  Agreement and  the transactions  contemplated
thereby,  and recommending that all shareholders tender their Shares pursuant to
the Offer, the Board of Directors considered a number of factors, including:
 
       (i) the financial  and other  terms  of the  Offer,  the Merger  and  the
           Acquisition Agreement;
 
       (ii)that the $16.125 per Share tender offer price represents a premium of
           approximately  32% over the closing price of the Shares on the NASDAQ
    National Market System ("NMS") on June  14, 1996, the last full trading  day
    prior  to  the  public  announcement of  the  execution  of  the Acquisition
    Agreement;
 
       (iii)
           recent trading prices of  the Shares on the  NMS, including the  fact
           that  the Shares have not traded at or above the $16.125 tender offer
    price in more than fifteen (15) years;
 
       (iv)the written opinion of Wheat delivered to the Board on June 15, 1996,
           to the effect that, as  of that date, and  based upon its review  and
    analysis and subject to the limitations set forth therein, the consideration
    to  be received by the  holders of the Shares pursuant  to the Offer and the
    Merger as  contemplated  in  the  Acquisition  Agreement  is  fair,  from  a
    financial  point of view, to such holders.  The full text of Wheat's written
    opinion, which sets  forth, among  other things,  assumptions made,  matters
    considered  and limitations on the review  undertaken, is attached hereto as
    Exhibit J and is incorporated herein by reference. Shareholders are urged to
    read the opinion in its entirety. Wheat's opinion is directed to the  Board,
    addresses  only the fairness of the  consideration to be received by holders
    of the Shares  from a  financial point  of view  and does  not constitute  a
    recommendation  to  any shareholder  as to  whether such  shareholder should
    accept the Offer and tender its Shares;
 
       (v) the  view  of  the  Board  of  Directors,  based  in  part  upon  the
           presentations of management and of Wheat to the Board of Directors on
    May  24 and again on  June 15, 1996, regarding  the likelihood of a superior
    offer arising;
 
       (vi)the  continuing  consolidation  in  the  rail  industry,  encouraging
           consolidation among suppliers, as well, to compete effectively;
 
       (vii)
           the  Company's long-term and short-term  prospects and capital needs,
           especially in  light  of  the developing  market  for  the  Company's
    automotive one-way clutch products;
 
       (viii)
            the provisions of the Acquisition Agreement, including the provision
           allowing  the Company to respond  to unsolicited inquiries concerning
    an acquisition of the Company, and  the provisions which permit the  Company
    to terminate the Acquisition Agreement upon payment to
 
                                       16

    Purchaser  of a break-up fee  in the amount set  forth in the description of
    the Acquisition Agreement set forth in  Item 3(b)(2), in the event that  the
    Board   of  Directors   determines  to  withdraw   its  recommendation  that
    shareholders accept the Offer based on the Board of Directors' determination
    that such action  is necessary  to comply  with its  fiduciary duties  under
    applicable law;
 
       (ix)the  fact  that Varlen's  and the  Purchaser's obligations  under the
           Offer were not subject to any financing condition;
 
       (x) the familiarity of the Board of Directors with the business,  results
           of  operations, properties and financial condition of the Company and
    the nature of the industry in which it operates; and
 
       (xi)the Board of Directors' belief that the transactions contemplated  by
           the  Acquisition Agreement would result  in relatively few changes to
    the Company's  operations and  customer relationships,  and that  employment
    opportunities  within the combined companies would offer growth and security
    to the Company's employees.
 
    The foregoing discussion of the information and factors considered and given
weight by the Board of  Directors is not intended to  be exhaustive. In view  of
the  variety  of factors  considered in  connection with  its evaluation  of the
Acquisition Agreement and  the Offer,  the Board of  Directors did  not find  it
practicable  to, and did  not, quantify or otherwise  assign relative weights to
the specific  factors considered  in reaching  its determination.  In  addition,
individual members of the Board of Directors may have given different weights to
different factors.
 
ITEM 5. PERSONS RETAINED, EMPLOYED OR TO BE COMPENSATED.
 
    Pursuant to an engagement letter dated May 31, 1996, between the Company and
Wheat,  the  Company retained  Wheat to  render  certain financial  advisory and
investment banking  services  to  the  Company in  connection  with  a  possible
business  combination. Pursuant  to this  engagement, one  of the  services that
Wheat agreed to provide was a written opinion to the Board of the Company as  to
the  fairness  of  the consideration,  to  be  received by  shareholders  of the
Company, from a financial point of view in connection with the proposed sale  of
the  Company to Varlen. Pursuant to the Engagement Letter, the Company agreed to
pay Wheat a fee of $50,000 after the delivery of an oral opinion to the Board by
Wheat as to the fairness of the consideration to received in the transaction  by
the Company's shareholders, from a financial point of view; an additional fee of
$150,000  at the time  the opinion is included  in a proxy  statement or a 14D-9
recommendation to the shareholders; and an additional $150,000 payable upon  the
closing  of the transaction. In addition,  the Company agreed to reimburse Wheat
for reasonable out-of-pocket expenses incurred (including reasonable legal  fees
and expenses) in performing its services under the Engagement Letter, whether or
not  the transaction is consummated or  the engagement terminates or expires. In
addition, the Company has agreed to indemnify Wheat and certain related  persons
against  certain liabilities  related to  or arising  out of  Wheat's engagement
under the Engagement Letter.
 
    In the ordinary course of business,  Wheat and its affiliates may trade  the
equity  securities of the Company for their  own account and for the accounts of
customers and, accordingly, may  at any time  hold a long  or short position  in
such  securities.  Wheat  has  in  the  past  provided  financial  advisory  and
investment banking services to the Company for which services they have received
customary fees.
 
    Wheat is  a nationally  recognized investment  banking firm  engaged in  the
evaluation  of businesses  and their securities  in connection  with mergers and
acquisitions, negotiated primary and secondary underwritings, private placements
and valuations for corporate and other  purposes. The Company selected Wheat  as
its  financial  advisor based  upon  its familiarity  with  the Company  and the
industry  in  which  the  Company  operates  and  its  experience,  ability  and
reputation with respect to mergers and acquisitions.
 
                                       17

    Except  as disclosed herein or in the Offer to Purchase, neither the Company
nor any  person acting  on its  behalf currently  intends to  employ, retain  or
compensate any other person to make solicitations or recommendations to security
holders on its behalf concerning the Offer or the Merger.
 
ITEM 6. RECENT TRANSACTIONS AND INTENT WITH RESPECT TO SECURITIES.
 
    (a)  SHARE TRANSACTIONS IN LAST 60 DAYS. Except for exercises of outstanding
options, during the past 60 days,  no transactions in shares have been  effected
