                  In the course of the discussions  between  representatives  of
the Parent and the Company,  certain projections of future operating performance
of the Company  were  furnished  to Parent's  representatives.  The  projections
indicated (i) estimated  revenues of the Company of $591 million for 1999;  (ii)
estimated  net income of the Company of 21.1 million for 1999;  (iii)  estimated
earnings per share for the Company of $.96 for 1999 and (iv) estimated EBITDA of
the Company of 72.4 million in 1999.

                  These  projections  were not  prepared  with a view to  public
disclosure  or compliance  with  published  guidelines of the  Commission or the
guidelines established by the American Institute of Certified Public Accountants
regarding  projections,  and are included in this Offer to Purchase only because
they were  provided to Parent.  Neither the Parent,  the  Purchaser,  nor any of
their respective  advisors assumes any  responsibility for the accuracy of these
projections.  While presented with numerical specificity,  these projections are
based upon a variety of assumptions (including,  without limitation, the sale of
APG Lime and the sale of Ameri-Forge  during 1999) relating to the businesses of
the Company (on a stand alone  basis)  which may not be realized and are subject
to significant  uncertainties  and  contingencies,  many of which are beyond the
control of the Company.  There can be no assurance that the projections  will be
realized, and actual results may vary materially from those shown.

                  The  discussion  set  forth  in  Section  10 of the  Offer  to
Purchase is hereby amended and supplemented as follows:

                  The  Purchaser  estimates  that the total  amount of funds now
required to acquire Shares pursuant to the Offer,  as supplemented  and amended,
to pay all related costs and expenses,  will be approximately $231 million.  See
"Fees and Expenses" in Section 16 of the Offer to Purchase.  The Purchaser plans
to obtain the necessary funds through capital  contributions or advances made by
the Parent.

                  6. MISCELLANEOUS. The Parent and the Purchaser have filed with
the SEC  amendments to the Schedule  14D-1 pursuant to Rule 14d-3 of the General
Rules and  Regulations  under the Securities  Exchange Act,  furnishing  certain
additional  information  with  respect  to  the  Offer,  and  may  file  further
amendments thereto.  The Schedule 14D-1, and any amendments  thereto,  including
exhibits,  may be inspected at, and copies may be obtained from, the same places
and in the same  manner  as set  forth in  Section  8 of the  Offer to  Purchase
(except that they will not be available at the regional offices of the SEC).

                  Except as modified by this Supplement,  the terms set forth in
the Offer to Purchase and the related Letters of Transmittal  remain  applicable
in all respects to the Offer and this  Supplement  should be read in conjunction
with the Offer to Purchase and the related Letters of Transmittal.

WITH THE OFFER TO PURCHASE.  Although such BLUE Letter of Transmittal  indicates
that the Offer will  expire at 12:00  midnight,  New York City time,  on Friday,
January 15, 1999, stockholders will be able to tender (or withdraw) their
Shares  pursuant  to the Offer  until  12:00  midnight,  New York City time,  on

DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF
DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY

accepted and no fractional Shares will be purchased. By execution of this Letter
of Transmittal (or a facsimile  hereof),  all tendering  stockholders  waive any
right to receive any notice of the acceptance of their Shares for payment.

                  3.  Inadequate  Space.  If the  space  provided  herein  under
"Description of Shares  Tendered" is inadequate,  the Certificate  numbers,  the
number  of  Shares  evidenced  by such  Certificates  and the  number  of Shares
tendered should be listed on a separate schedule and attached hereto.

                  4. Partial Tenders. (Not applicable to stockholders who tender
by  book-entry  transfer.)  If  fewer  than  all  the  Shares  evidenced  by any
Certificate delivered to the Depositary herewith are to be tendered hereby, fill

more persons, all such persons must sign this Letter of Transmittal.

                  If any of the Shares  tendered  hereby are  registered  in the
names of different holders, it will be necessary to complete, sign and submit as
many separate  Letters of  Transmittal as there are different  registrations  of
such Certificates.

                  If this  Letter of  Transmittal  is  signed by the  registered
holder(s) of the Shares  tendered  hereby,  no  endorsements  of Certificates or
separate  stock  powers  are  required,  unless  payment  is to be made  to,  or
Certificates evidencing Shares not tendered or not purchased are to be issued in
the name of, a person other than the  registered  holder(s),  in which case, the
Certificate(s)  evidencing  the  Shares  tendered  hereby  must be  endorsed  or
accompanied  by appropriate  stock powers,  in either case signed exactly as the
name(s) of the registered holder(s) appear(s) on such Certificate(s). Signatures
on such  Certificate(s)  and stock  powers  must be  guaranteed  by an  Eligible

power   is   signed   by   a   trustee,   executor,   administrator,   guardian,
attorney-in-fact, officer of a corporation or other person acting in a fiduciary
or  representative  capacity,  such person should so indicate when signing,  and
proper evidence  satisfactory to Purchaser of such person's  authority so to act
must be submitted.

                  6. Stock Transfer Taxes.  Except as otherwise provided in this
Instruction  6,  Purchaser will pay all stock transfer taxes with respect to the
sale and  transfer of any Shares to it or its order  pursuant to the Offer.  If,
however,

<PAGE>
payment  of the  purchase  price of any  Shares  purchased  is to be made to, or
Certificate(s)  evidencing Shares not tendered or not purchased are to be issued
in the name of, a person other than the registered holder(s),  the amount of any
stock transfer taxes (whether  imposed on the registered  holder(s),  such other
person or  otherwise)  payable on account of the  transfer to such other  person
will be  deducted  from the  purchase  price of such  Shares  purchased,  unless
evidence  satisfactory  to Purchaser of the payment of such taxes,  or exemption
therefrom,  is submitted.  Except as provided in this Instruction 6, it will not
be  necessary  for  transfer  tax  stamps to be  affixed  to the  Certificate(s)
evidencing the Shares tendered hereby.

                  7. Special Payment and Delivery  Instructions.  If a check for
the  purchase  price  of  any  Shares  tendered  hereby  is  to  be  issued,  or
Certificate(s) evidencing Shares not tendered or not purchased are to be issued,

Transmittal  or if such check or any such  Certificate  is to be sent to someone
other than the person(s)  signing this Letter of Transmittal or to the person(s)
signing this Letter of  Transmittal  but at an address  other than that shown in
the box entitled "Description of Shares Tendered," the appropriate boxes on this
Letter of Transmittal  must be completed.  Shares  tendered hereby by book-entry
transfer  may request  that  Shares not  purchased  be credited to such  account
maintained at the Book-Entry Transfer Facility as such stockholder may designate
in the box entitled "Special Payment  Instructions" on the reverse hereof. If no
such  instructions  are given, all such Shares not purchased will be returned by
crediting the account at the  Book-Entry  Transfer  Facility as the account from
which such Shares were delivered.

                  8. Requests for Assistance or Additional Copies.  Requests for
assistance  may be  directed to the  Information  Agent at its address and phone
number  set  forth  herein.  Additional  copies of the  Offer to  Purchase,  the
Supplement, the revised GOLD Letter of Transmittal, the revised GREY  Notice of
Guaranteed   Delivery  and  the   Guidelines  for   Certification   of  Taxpayer
Identification   Number  on  Substitute  Form  W-9  may  be  obtained  from  the
Information Agent or from brokers, dealers, commercial banks or trust companies.

                  9. Substitute Form W-9. Each tendering stockholder is required
to provide the Depositary with a correct Taxpayer  Identification Number ("TIN")
on the Substitute Form W-9 which is provided under  "Important Tax  Information"
below, and to certify,  under penalties of perjury,  that such number is correct
and that such stockholder is not subject to backup withholding of federal income
tax. If a  tendering  stockholder  has been  notified  by the  Internal  Revenue
Service that such stockholder is subject to backup withholding, such stockholder
must cross out item (2) of the  Certification  box of the  Substitute  Form W-9,
unless such  stockholder has since been notified by the Internal Revenue Service
that such  stockholder  is no longer subject to backup  withholding.  Failure to
provide the  information  on the  Substitute  Form W-9 may subject the tendering
stockholder to 31% federal income tax withholding on the payment of the purchase
price  of  all  Shares  purchased  from  such  stockholder.   If  the  tendering
stockholder  has not been  issued a TIN and has  applied  for one or  intends to
apply for one in the near future, such stockholder should write "Applied For" in
the space  provided for the TIN in Part I of the  Substitute  Form W-9, and sign
and date the Substitute  Form W-9. If "Applied For" is written in Part I and the
Depositary  is not  provided  with a TIN  within 60 days,  the  Depositary  will
withhold 31% on all payments of the purchase price to such  stockholder  until a
TIN is provided to the Depositary.

                  10.   Lost,   Destroyed   or  Stolen   Certificates.   If  any
Certificate(s)  representing  Shares has been  lost,  destroyed  or stolen,  the
stockholder should promptly notify the Depositary.  The stockholder will then be
instructed  as to the  steps  that  must  be  taken  in  order  to  replace  the
Certificate(s).  This  Letter of  Transmittal  and related  documents  cannot be
processed until the procedures for replacing lost or destroyed Certificates have
been followed.

                  IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE HEREOF),
PROPERLY COMPLETED AND DULY EXECUTED, WITH ANY REQUIRED SIGNATURE GUARANTEES, OR
AN AGENT'S  MESSAGE  (TOGETHER WITH  CERTIFICATES  FOR SHARES OR CONFIRMATION OF
BOOK-ENTRY  TRANSFER AND ALL OTHER  REQUIRED  DOCUMENTS)  OR, IF  APPLICABLE,  A
PROPERLY  COMPLETED  AND DULY  EXECUTED  NOTICE OF  GUARANTEED  DELIVERY MUST BE
RECEIVED BY THE DEPOSITARY PRIOR TO THE EXPIRATION DATE.

                            IMPORTANT TAX INFORMATION

                  Under the federal income tax law, a stockholder whose tendered
Shares are accepted for payment is required by law to provide the Depositary (as
payer) with such stockholder's correct TIN on Substitute Form W-9 below. If such
stockholder  is an individual,  the TIN is such  stockholder's  social  security
number.  If the Depositary is not provided with the correct TIN, the stockholder
may be subject to a $50 penalty  imposed by the  Internal  Revenue  Service.  In
addition,  payments  that are made to such  stockholder  with  respect to Shares
purchased pursuant to the Offer may be subject to backup withholding of 31%.

                  Certain   stockholders    (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 as an exempt recipient, such individual must submit a statement,  signed
under penalties of perjury,  attesting to such individual's exempt status. Forms
of such  statements  can be  obtained  from  the  Depositary.  See the  enclosed
Guidelines for  Certification  of Taxpayer  Identification  Number on Substitute
Form W-9 for additional instructions.

                  If backup  withholding  applies with respect to a stockholder,
the  Depositary  is  required  to  withhold  31% of any  payments  made  to such
stockholder.  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.

PURPOSE OF SUBSTITUTE FORM W-9

                  To prevent  backup  withholding on payments that are made to a
stockholder  with  respect  to  Shares  purchased  pursuant  to the  Offer,  the
stockholder is required to notify the Depositary of such  stockholder's  correct
TIN by  completing  the form  below  certifying  (a) that  the TIN  provided  on
Substitute Form W-9 is correct (or that such stockholder is awaiting a TIN), and
(b) that (i) such  stockholder  has not been  notified by the  Internal  Revenue
Service that such stockholder is subject to backup  withholding as a result of a
failure to report all interest or dividends or (ii) the Internal Revenue Service
has notified such  stockholder  that such  stockholder  is no longer  subject to
backup withholding.

WHAT NUMBER TO GIVE THE DEPOSITARY

                  The  stockholder is required to give the Depositary the social
security  number or employer  identification  number of the record holder of the
Shares  tendered  hereby.  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.  If the tendering  stockholder  has not been issued a
TIN and has  applied  for a number or  intends to apply for a number in the near
future, the stockholder should write "Applied For" in the space provided for the
TIN in Part I, and sign and date the  Substitute  Form W-9. If "Applied  For" is
written in Part I and the  Depositary is not provided with a TIN within 60 days,
the  Depositary  will withhold 31% of all payments of the purchase price to such
stockholder until a TIN is provided to the Depositary.
