Ladies and Gentlemen:
 
    The undersigned hereby  tenders to  BAS, Inc., a  Virginia corporation  (the
"Purchaser")  and a  wholly owned subsidiary  of Varlen  Corporation, a Delaware
corporation ("Varlen"), the  above-described shares of  Common Stock, par  value
$1.00  per share (the "Shares"), of Brenco, Incorporated, a Virginia corporation
(the "Company"), pursuant to the  Purchaser's offer to purchase all  outstanding
Shares  at a price of $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  in this Letter  of
Transmittal (which together constitute the "Offer"), receipt of which are hereby
acknowledged.  The undersigned understands that the Purchaser reserves the right
to transfer or assign, in whole or from  time to time in part, to Varlen or  one
or  more of its other direct or  indirect wholly owned subsidiaries the right to
purchase all or any portion of the Shares tendered pursuant to the Offer.
 
    Subject to,  and  effective upon,  acceptance  for payment  for  the  Shares
tendered  herewith in accordance with the terms and subject to the conditions of
the Offer, the undersigned hereby sells, assigns, and transfers to, or upon  the
order  of, the Purchaser all right, title and  interest in and to all the Shares
that are  being  tendered  hereby  (and  any and  all  other  Shares  and  other
securities  and  property issued  or  issuable or  distributed  or distributable
(other than the Company's regular quarterly  dividend of not more than $.07  per
Share) in respect thereof on or after June 15, 1996 and prior to the transfer to
the  name of  the Purchaser  or nominee  or transferee  of the  Purchaser on the
Company's stock transfer records of the Shares tendered herewith  (collectively,
a  "Distribution")), and irrevocably constitutes and appoints the Depositary the
true and lawful agent  and attorney-in-fact of the  undersigned with respect  to
such  Shares (and any Distribution) with  full power of substitution (such power
of attorney being deemed  to be an irrevocable  power coupled with an  interest)
to: (i) deliver certificates for such Shares (and any Distribution), or transfer
ownership  of such Shares (and any Distribution) on the account books maintained
by  a  Book-Entry  Transfer  Facility,  together  in  any  such  case  with  all
accompanying evidences of transfer and authenticity, to or upon the order of the
Purchaser,  upon receipt by  the Depositary, as the  undersigned's agent, of the
purchase price (adjusted, if appropriate, as provided in the Offer to Purchase);
(ii) present such Shares (and any Distribution) for transfer on the books of the
Company; and (iii)  receive all benefits  and otherwise exercise  all rights  of
beneficial  ownership of such  Shares (and any  Distribution), all in accordance
with the terms and subject to the conditions of the Offer.
 
    The undersigned hereby irrevocably appoints the Purchaser, its officers  and
its  designees,  and each  of  them, the  attorneys-in-fact  and proxies  of the
undersigned, each with full  power of substitution, to  exercise all voting  and
other rights of the undersigned in such manner as each such attorney-in-fact and
proxy  or the substitute  for any such  attorney-in-fact and proxy  shall in the
sole discretion of each such attorney-in-fact and proxy or his substitutes  deem
proper,  and otherwise act (including pursuant  to written consent) with respect
to all of  the Shares  tendered hereby (and  any Distribution)  which have  been
accepted  for payment by the  Purchaser prior to the time  of such vote or other
action and  which  the  undersigned  is  entitled to  vote  at  any  meeting  of
shareholders  (whether  annual  or  special  and  whether  or  not  an adjourned
meeting), or consent in lieu  of any such meeting,  or otherwise. THIS PROXY  IS
IRREVOCABLE AND COUPLED WITH AN INTEREST AND IS GRANTED IN CONSIDERATION OF, AND
IS  EFFECTIVE UPON, THE ACCEPTANCE  FOR PAYMENT OF SUCH  SHARES BY THE PURCHASER

IN ACCORDANCE WITH  THE TERMS OF  THE OFFER. SUCH  ACCEPTANCE FOR PAYMENT  SHALL
REVOKE,  WITHOUT FURTHER ACTION, ANY OTHER POWER OF ATTORNEY AND/ OR PROXY GIVEN
BY  THE  UNDERSIGNED  AT  ANY  TIME  WITH  RESPECT  TO  SUCH  SHARES  (AND   ANY
DISTRIBUTION)  AND NO SUBSEQUENT POWER OF ATTORNEY OR PROXY MAY BE GIVEN (AND IF
GIVEN WILL  NOT BE  EFFECTIVE)  WITH RESPECT  THERETO  BY THE  UNDERSIGNED.  The
undersigned  understands  that the  Purchaser  expressly reserves  the  right to
require that, in order for Shares  to be validly tendered, immediately upon  the
Purchaser's  acceptance for payment  of such Shares  (and any Distribution), the
Purchaser is able to exercise  full voting rights and  other rights of a  record
and  beneficial holder thereof, including rights in respect of acting by written
consent with respect  to such  Shares (and any  Distribution) or  voting at  any
meeting of shareholders.
 
    The undersigned hereby represents and warrants that: (i) the undersigned has
full  power  and  authority to  tender,  sell,  assign and  transfer  the Shares
tendered hereby (and any Distribution) and  (ii) when the same are accepted  for
payment  by  the  Purchaser, the  Purchaser  will acquire  good,  marketable and
unencumbered title thereto, free and  clear of all liens, restrictions,  charges
and  encumbrances and  the same will  not be  subject to any  adverse claim. The
undersigned, upon request,  will execute  and deliver  any additional  documents
deemed  by the Depositary, the Purchaser or  Varlen to be necessary or desirable
to complete the sale, assignment and transfer of the Shares tendered hereby (and
any Distribution).  In  addition,  the  undersigned  shall  promptly  remit  and
transfer  to the Depositary  for the account  of the Purchaser  the whole of any
dividend (other than the Company's regular  quarterly dividend of not more  than
$.07  per  Share),  distribution,  interest  payment  or  right  issued  to  the
undersigned on or after June 15, 1996, in respect of the Shares tendered hereby,
accompanied by appropriate documentation  of transfer. Pending such  remittance,
the  Purchaser shall be  entitled to all  rights and privileges  as owner of any
such dividend,  distribution, interest  payment or  right and  may withhold  the
entire  purchase price  or deduct  from the purchase  price the  amount or value
thereof, as determined by the Purchaser in its sole discretion.
 
    All authority herein conferred or agreed  to be conferred in this Letter  of
Transmittal shall not be affected by, and shall survive, the death or incapacity
of  the undersigned,  and any obligation  of the undersigned  hereunder shall be
binding upon the successors, assigns, heirs, executors, administrators and legal
representatives of the undersigned. Except as  stated in the Offer to  Purchase,
this tender is irrevocable.
 
    The undersigned understands that the tender of Shares pursuant to any of the
procedures  described  in  Section  4  of  the  Offer  to  Purchase  and  in the
instructions hereto will  constitute the tendering  shareholder's acceptance  of
the  terms and conditions of  the Offer, as well  as the tendering shareholder's
representation and  warranty  that  such  shareholder has  the  full  power  and
authority  to tender and  assign the Shares tendered  (and any Distribution), as
specified in this Letter of Transmittal. The Purchaser's acceptance for  payment
of  Shares pursuant to the Offer will constitute a binding agreement between the
tendering shareholder  and the  Purchaser  upon the  terms  and subject  to  the
conditions of the Offer.
 
    Unless  otherwise  indicated  herein under  "Special  Payment Instructions,"
please issue the check for the purchase price and/or any certificates for Shares
not tendered  or  accepted  for  payment in  the  name(s)  of  the  undersigned.

please mail the check for the purchase price and/or return any certificates  for
Shares  not tendered  or accepted  for payment  (and accompanying  documents, as

accepted for payment  in the name(s)  of, and deliver  said check and/or  return
such  certificates  to,  the person  or  persons so  indicated.  The undersigned
recognizes that the Purchaser has no obligation pursuant to the Special  Payment
Instructions  to  transfer any  Shares from  the name  of the  registered holder
thereof if  the Purchaser  does not  accept for  payment any  of the  Shares  so
tendered.

 Identification Number within sixty (60) days.

                                  INSTRUCTIONS
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
    1.   GUARANTEE OF  SIGNATURES.  No  signature guarantee is  required on this
Letter of  Transmittal  (a) if  this  Letter of  Transmittal  is signed  by  the
registered  holder(s) (which term, for purposes  of this document, shall include
any participant  in a  Book-Entry  Transfer Facility  whose  name appears  on  a
security  position listing as the owner  of Shares) of Shares tendered herewith,
unless such holder(s)  has completed  either the box  entitled "Special  Payment
Instructions"  or the box entitled "Special Delivery Instructions" above, or (b)
if such Shares are tendered for the account  of a firm which is a bank,  broker,
dealer,  credit union, savings association or other  entity which is a member in
good standing of a recognized Medallion Signature Guarantee Program (each of the
foregoing being referred to as an  "Eligible Institution"). In all other  cases,
all  signatures on this Letter of Transmittal  must be guaranteed by an Eligible
Institution. See Instruction 5 of this Letter of Transmittal.
 
    2.  REQUIREMENTS OF TENDER.  This  Letter of Transmittal is to be  completed
by  shareholders either if certificates are  to be forwarded herewith or, unless
an Agent's  Message is  utilized, if  tenders are  to be  made pursuant  to  the
procedure  for tender by book-entry transfer set forth in Section 4 of the Offer
to Purchase.  Certificates  for  tendered  Shares,  or  timely  confirmation  (a
"Book-Entry  Confirmation") of  a book-entry  transfer of  such Shares  into the
Depositary's account at a Book-Entry Transfer  Facility, as well as this  Letter
of  Transmittal (or  a facsimile hereof),  properly completed  and duly executed
with any required signature guarantees, or an Agent's Message in connection with
a book-entry  transfer, and  any  other documents  required  by this  Letter  of
Transmittal,  must be  received by  the Depositary at  one of  its addresses set
forth on the front page  of this Letter of  Transmittal prior to the  Expiration
Date.  Shareholders  whose certificates  are  not immediately  available  or who
cannot deliver  their  certificates and  all  other required  documents  to  the
Depositary prior to the Expiration Date or who cannot complete the procedure for
delivery  by book-entry transfer  on a timely  basis may tender  their Shares by
properly completing and duly executing a Notice of Guaranteed Delivery  pursuant
to  the guaranteed  delivery procedure set  forth in  Section 4 of  the Offer to
Purchase. Pursuant to such procedure: (i) such tender must be made by or through
an Eligible Institution; (ii) a properly  completed and duly executed Notice  of
Guaranteed  Delivery, substantially in the form made available by the Purchaser,
must be received by the Depositary prior  to the Expiration Date; and (iii)  the
certificates (or a Book-Entry Confirmation) representing all tendered Shares, in
proper  form for transfer, in each case  together with the Letter of Transmittal
(or a facsimile thereof), properly completed and duly executed with any required
signature guarantees  (or, in  the case  of a  book-entry delivery,  an  Agent's
Message) and any other documents required by this Letter of Transmittal, must be
received  by  the Depositary  within  three National  Association  of Securities
Dealers, Inc. Automated  Quotation System ("NASDAQ  System") trading days  after
the date of execution of such Notice of Guaranteed Delivery. If certificates are
forwarded  separately to the Depositary, a  properly completed and duly executed
Letter of Transmittal must accompany each such delivery.
 
    THE METHOD OF  DELIVERY OF CERTIFICATES  FOR SHARES AND  ALL OTHER  REQUIRED
DOCUMENTS,  INCLUDING DELIVERY THROUGH  ANY BOOK-ENTRY TRANSFER  FACILITY, IS AT
THE OPTION AND RISK OF THE  TENDERING SHAREHOLDER. DELIVERY WILL BE DEEMED  MADE
ONLY  WHEN  ACTUALLY  RECEIVED  BY  THE  DEPOSITARY.  IF  DELIVERY  IS  BY MAIL,
REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY INSURED, IS RECOMMENDED.
IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.
 
    No alternative, conditional or contingent  tenders will be accepted, and  no
fractional  Shares will be purchased (unless you are tendering all of the Shares
you own). All tendering shareholders, by execution of this Letter of Transmittal
(or a facsimile hereof), waive any right to receive any notice of the acceptance
of their Shares for payment.
 
    3.   INADEQUATE SPACE.   If  the space  provided herein  is inadequate,  the
certificate  number(s)  and/or  the  number of  Shares  and  any  other required
information should be listed on a separate signed schedule attached hereto.
 
    4.   PARTIAL  TENDERS.    (NOT APPLICABLE  TO  SHAREHOLDERS  WHO  TENDER  BY
BOOK-ENTRY  TRANSFER.)  If  fewer  than  all  of  the  Shares  evidenced  by any
certificate delivered to the Depositary are  to be tendered, fill in the  number
of  Shares  which are  to  be tendered  in the  box  entitled "Number  of Shares
Tendered." In such  a case, new  Share certificate(s) for  the Shares that  were
evidenced  by your old Share certificate(s), but  were not tendered by you, will
be sent to you (unless otherwise provided in the appropriate box on this  Letter
of  Transmittal) as  soon as practicable  after the Expiration  Date. All Shares
represented by certificates delivered to the  Depositary will be deemed to  have
been tendered unless otherwise indicated.
 
    5.   SIGNATURES ON LETTER OF TRANSMITTAL, STOCK POWERS AND ENDORSEMENTS.  If
this Letter of Transmittal is signed  by the registered holder(s) of the  Shares
tendered hereby, the signature(s) must correspond with the name(s) as written on
the  face of  the certificate(s) without  alteration, enlargement  or any change
whatsoever.
 
    If any of  the Shares tendered  hereby are owned  of record by  two or  more
joint owners, all such owners must sign this Letter of Transmittal.
 
    If  any of the tendered Shares are  registered in different names on several
certificates, it will be necessary to complete, sign and submit as many separate
Letters of Transmittal as there are different registrations of certificates.
 
    If this Letter of Transmittal or any certificates or stock powers are signed
by trustees, executors,  administrators, guardians, attorneys-in-fact,  officers
of corporations or others acting in a fiduciary or representative capacity, such
persons should so indicate when signing, and proper evidence satisfactory to the
Purchaser of their authority so to act must be submitted.
 
    If  this Letter of Transmittal is signed  by the registered holder(s) of the
Shares listed  and  transmitted  hereby,  no  endorsements  of  certificates  or
separate  stock  powers  are  required  unless  payment  is  to  be  made  to or
certificates for Shares not tendered  or not purchased are  to be issued in  the
name  of  a  person other  than  the  registered holder(s).  Signatures  on such
certificates or stock powers must be guaranteed by an Eligible Institution.
 
    If this  Letter  of  Transmittal  is  signed by  a  person  other  than  the
registered  holder(s) of the  certificate(s) listed, the  certificate(s) must be
endorsed or  accompanied by  appropriate  stock powers,  in either  case  signed
exactly  as the name(s) of the registered holder(s) appear on the certificate(s)
for such  Shares.  Signatures on  such  certificates  or stock  powers  must  be
guaranteed by an Eligible Institution.
 
    6.   STOCK TRANSFER TAXES.  Except as otherwise provided in this Instruction
6, the Purchaser  will pay or  cause to be  paid any stock  transfer taxes  with
respect  to the transfer and sale  of Shares to it or  its order pursuant to the
Offer. If, however, payment of

the purchase  price is  to  be made  to, or  if  certificate(s) for  Shares  not
tendered or accepted for payment are to be registered in the name of, any person
other than the registered holder(s), if a transfer tax is imposed for any reason
other than the sale or transfer of Shares to Purchaser pursuant to the Offer, or
if  tendered certificate(s) are registered in the  name of any person other than
the person(s)  signing this  Letter  of Transmittal,  the  amount of  any  stock
transfer  taxes (whether  imposed on  the registered  holder(s) or  such person)
payable on account  of the transfer  to such  person will be  deducted from  the
purchase  price unless satisfactory evidence of the  payment of such taxes or an
exemption therefrom, is submitted.
 
    Except as otherwise provided in this Instruction 6, it will not be necessary
for transfer  tax stamps  to be  affixed to  the certificate(s)  listed in  this
Letter of Transmittal.
 
    7.    SPECIAL PAYMENT  AND  DELIVERY INSTRUCTIONS.    If the  check  for the
purchase price  of any  Shares purchased  is to  be issued,  or any  Shares  not
tendered or not purchased are to be returned, in the name of a person other than
the  person(s)  signing this  Letter  of Transmittal,  or  if the  check  or any
certificates for  Shares not  tendered or  not  purchased are  to be  mailed  to
someone  other than the person(s)  signing this Letter of  Transmittal or to the
person(s) signing this Letter of Transmittal at an address other than that shown
above, the appropriate boxes on this Letter of Transmittal should be  completed.
Shareholders tendering Shares by book-entry transfer may request that Shares not
purchased  be  credited  to  such  account at  any  of  the  Book-Entry Transfer
Facilities  as   such  shareholder   may   designate  under   "Special   Payment
Instructions."  If no such instructions are given, any such Shares not purchased
will be returned by crediting the account at the Book-Entry Transfer  Facilities
designated above.
 
    8.   IRREGULARITIES.   All  questions as  to the  form of  documents and the
validity, eligibility (including time of receipt) and acceptance for payment  of
any  tender  of  Shares  will  be  determined  by  the  Purchaser,  in  its sole
discretion, which  determination  shall  be final  and  binding.  The  Purchaser
reserves the absolute right to reject any or all tenders of Shares determined by
it  not to be  in proper form  or the acceptance  for payment of  or payment for
tenders of  Shares which  may, in  the opinion  of the  Purchaser's counsel,  be
unlawful.  The Purchaser also reserves the absolute right to waive any defect or
irregularity in any tender of Shares. No tender of Shares will be deemed to have
been properly made until  all defects and  irregularities relating thereto  have
been cured or waived. The Purchaser's interpretation of the terms and conditions
of  the Offer in this  regard will be final and  binding. None of the Purchaser,
the Dealer Manager, the  Depositary, the Information Agent  or any other  person
will  be under any  duty to give  notification of any  defect or irregularity in
tenders or incur any liability for failure to give any such notification.
 
    9.  31% BACKUP WITHHOLDING; SUBSTITUTE FORM W-9.  Under U.S. Federal  income
tax  law,  a  shareholder whose  tendered  Shares  are accepted  for  payment is
required to provide the Depositary with a correct Taxpayer Identification Number
("TIN"),  generally  the  shareholder's  social  security  or  federal  employer
identification  number, on  Substitute Form  W-9 below.  Failure to  provide the
information on the form may subject the tendering shareholder or other payee  to
a  $50 penalty. In addition, payments that are made to such shareholder or other
payee with respect to Shares purchased pursuant  to the Offer may be subject  to
31% federal income tax withholding on the payment of the purchase price.
 
    Certain  shareholders (including, among others, all corporations and certain
foreign individuals) are not subject  to these backup withholding and  reporting
requirements.  In order for a foreign individual to qualify an exempt recipient,
the shareholder  must submit  a Form  W-8, signed  under penalties  of  perjury,
attesting  that individual's exempt status. A Form  W-8 can be obtained from the
Depositary.  See  the  enclosed   "Guidelines  for  Certification  of   Taxpayer
Identification Number on Substitute Form W-9" for additional instructions.
 
    Backup  withholding is not  an additional tax. Rather,  the tax liability of
persons subject  to backup  withholding will  be reduced  by the  amount of  tax
withheld.  If withholding results  in an overpayment  of taxes, a  refund may be
obtained from the Internal Revenue Service.
 
    To prevent backup  withholding on payments  that are made  to a  shareholder
with  respect  to Shares  purchased pursuant  to the  Offer, the  shareholder is
required  to  notify  the  Depositary  of  such  shareholder's  correct  TIN  by
completing  the Substitute Form W-9 certifying (i)  that the TIN provided on the
Substitute Form W-9 is correct (or that such shareholder is awaiting a TIN)  and
(ii)  that (a) such  shareholder has not  been notified by  the Internal Revenue
Service that such shareholder is subject to backup withholding as a result of  a
failure  to report all interest or dividends or (b) the Internal Revenue Service
has notified such  shareholder that  such shareholder  is no  longer subject  to
backup withholding.
 
    The box in part 3 of the Substitute Form W-9 may be checked if the tendering
shareholder  has not been issued a  TIN and has applied for  a TIN or intends to
apply for  a TIN  in the  near future.  If the  box in  Part 3  is checked,  the
shareholder  or  other  payee must  also  complete the  Certificate  of Awaiting
Taxpayer  Identification   Number  in   order  to   avoid  backup   withholding.
Notwithstanding  that  the box  in  part 3  is  checked and  the  Certificate of
Awaiting Taxpayer  Identification Number  is completed,  if the  shareholder  or
other  payee does not provide a properly  certified TIN to the Depositary within
60 days, the Depositary will withhold 31% of all payments made prior to the time
a properly certified TIN is provided to the Depositary.
 
    The shareholder  is required  to  give the  Depositary the  social  security
number or employer identification number of the record owner of the Shares or of
the  last transferee appearing on the transfers attached to, or endorsed on, the
Shares. If the Shares are in  more than one name or are  not in the name of  the
actual  owner, consult  the enclosed  "Guidelines for  Certification of Taxpayer
Identification Number on Substitute Form  W-9" for additional guidance on  which
number to report.

    11.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any certificate  evidencing
Shares  has  been lost,  destroyed or  stolen,  the shareholder  should promptly
notify Wachovia  Bank of  North Carolina,  N.A., Winston  Salem, North  Carolina
27102-3001, Attention: Darrell V. Milton at (919) 770-4994. The shareholder will

certificate.  This  Letter  of  Transmittal  and  related  documents  cannot  be
