Dear Fellow Stockholder:
 
  You are cordially invited to attend a Special Meeting of Stockholders (the
"Special Meeting") of Ocal, Inc., a Delaware corporation (the "Company") to be
held on Tuesday, January 5, 1999, at 8:00 a.m. local time at the Airtel Plaza
Hotel, 7277 Valjean Avenue, Van Nuys, California 91406. At the Special Meeting,
you will be asked to approve the Merger (as defined below) and approve and
adopt the Agreement and Plan of Merger dated as of October 6, 1998 (the "Merger
Agreement"), among Thomas & Betts Corporation, a Tennessee corporation ("T&B"),
Ocal Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of
T&B ("Merger Sub"), the Company, and certain stockholders of the Company,
pursuant to which Merger Sub will be merged with and into the Company and the
Company, as the surviving corporation of the Merger, will become a wholly-owned
subsidiary of T&B (the "Merger"). If the Merger is consummated, each share of
the Company's common stock, par value $0.001 per share, will be converted in
the Merger into the right to receive $3.54 in cash, subject to adjustment under
certain circumstances as described in the enclosed Proxy Statement.
 
  The Company's financial advisor, Houlihan Lokey Howard & Zukin Financial
Advisors, Inc., has rendered an opinion to the effect that, as of the date of
its opinion and based upon the reasoning described therein, the consideration
to be received by the Company's stockholders in the Merger is fair to the
Company's stockholders from a financial point of view.
 
  THE BOARD OF DIRECTORS OF THE COMPANY BELIEVES THE PROPOSED MERGER IS
ADVISABLE AND IN THE BEST INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS AND
RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE MERGER AND APPROVAL AND ADOPTION
OF THE MERGER AGREEMENT.
 
  For the Merger to be consummated, holders of a majority of the outstanding
shares of Common Stock must vote in person or by proxy to approve the Merger
and to approve and adopt the Merger Agreement at the Special Meeting. I have
agreed to vote my shares, and shares that I control held by my family
partnership, in favor of the Merger and the Merger Agreement. Since these
shares represent 54% of the outstanding Common Stock, if such shares are so
voted, the Merger will be approved and the Merger Agreement will be approved
and adopted without any action on the part of any other stockholder of the
Company.
 
  The enclosed Proxy Statement contains detailed information concerning the
terms and conditions to the Merger and the reasons your Board of Directors has
determined to submit it for your approval. Please read and carefully consider
the information presented in the Proxy Statement and complete, date, sign and
return the enclosed proxy card in the accompanying prepaid envelope.
 
                                        Sincerely,
                                        
                                        /s/ Ilan Bender

                              PROXY STATEMENT FOR
                        SPECIAL MEETING OF STOCKHOLDERS
 
                               ----------------
 
                          TO BE HELD JANUARY 5, 1999
 
  This Proxy Statement ("Proxy Statement") is being furnished to the
stockholders of Ocal, Inc., a Delaware corporation (the "Company"), in
connection with the solicitation of proxies by the Board of Directors from
holders of outstanding shares of common stock, $0.001 par value, of the
Company (the "Common Stock") for use at the Special Meeting of Stockholders
(including any adjournments or postponements thereof, the "Special Meeting"),
to be held at 8:00 a.m. local time on Tuesday, January 5, 1999, at the Airtel
Plaza Hotel, 7277 Valjean Avenue, Van Nuys, California 91406.
 
  At the Special Meeting, holders of Common Stock (the "Stockholders") will
consider and vote upon a proposal to approve the Merger (as defined below) and
approve and adopt the Agreement and Plan of Merger dated as of October 6, 1998
(the "Merger Agreement"), among Thomas & Betts Corporation, a Tennessee
corporation ("T&B"), Ocal Acquisition Corp., a Delaware corporation and
wholly-owned subsidiary of T&B ("Merger Sub"), the Company, and certain
Stockholders of the Company, pursuant to which (i) Merger Sub will be merged
with and into the Company and the Company, as the surviving corporation of the
Merger, will become a wholly-owned subsidiary of T&B (the "Merger"), and (ii)
each share of Common Stock that is outstanding at the effective time of the
Merger (other than shares of Common Stock as to which dissenters' rights, if
any, are perfected) will be converted into the right to receive $3.54 in cash
subject to adjustment under certain circumstances (on an aggregate basis, the
"Merger Consideration;" on a per share basis, the "Per Share Merger
Consideration"). See "The Merger Agreement--Merger Consideration Adjustment."
 
  Consummation of the Merger is conditioned upon, among other things, approval
of the Merger and approval and adoption of the Merger Agreement by the
requisite vote of the Stockholders, the receipt of certain consents and the
expiration or termination of certain waiting provisions under the Hart-Scott-
Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act"). The
Special Meeting may be postponed or adjourned under certain circumstances.
There can be no assurance that the conditions to the Merger will be satisfied
or, where permissible, waived or that the Merger will be consummated. For
further information concerning the terms and conditions of the Merger, see
"The Merger" and "The Merger Agreement."
 
  A copy of the Merger Agreement is included in this Proxy Statement as Annex
A and is incorporated herein by reference. The summaries of the portions of
the Merger Agreement set forth in this Proxy Statement do not purport to be
complete and are subject to, and qualified in their entirety by reference to,
the text of the Merger Agreement.
 
  For the Merger to be consummated, holders of a majority of the outstanding
shares of Common Stock must vote in person or by proxy to approve the Merger
and approve and adopt the Merger Agreement at the Special Meeting. Ilan
Bender, the Chairman of the Board of Directors, Chief Executive Officer and
President of the Company, who beneficially holds, on behalf of himself and a
family partnership over which he has voting control, approximately 54% of the
outstanding shares of Common Stock, has agreed to vote his shares in favor of
the Merger and the Merger Agreement. Therefore, the holder of shares of Common
Stock sufficient to approve the Merger and approve and adopt the Merger
Agreement has agreed to vote for the approval of the Merger and the approval
and adoption of the Merger Agreement and, if such shares are so voted, the
Merger will be approved and the Merger Agreement will be approved and adopted
without any action on the part of any other Stockholder. For further
information concerning the terms and conditions of this agreement, see "The
Merger Agreement."

Inc., financial advisor to the Company ("Houlihan Lokey"), as to the fairness
from a financial point of view of the Merger Consideration to be received by

perfecting appraisal rights. See "The Merger--Specific Rights of Dissenting
Stockholders" and Annex C hereto.

the Merger has been approved and the Merger Agreement approved and adopted,
abstentions and broker non-votes will be treated as votes against the proposal.
See "Voting and Proxies."
 
  The Majority Stockholder. Under the terms of the Merger Agreement, Mr.
Bender, who beneficially holds, on behalf of himself and a family partnership
over which he has voting control, approximately 54% of the outstanding shares
of Common Stock, has agreed to vote his shares in favor of approval of the
Merger and approval and adoption of the Merger Agreement at the Special
Meeting. Therefore, assuming such shares are so voted, the Merger will be
approved and the Merger Agreement will be approved and adopted without any
action on the part of any other Stockholder. See "The Merger Agreement--The
Majority Stockholder."
 
RECOMMENDATION OF THE BOARD OF DIRECTORS
 
  The Board of Directors of the Company (the "Board of Directors" or the
"Board") has unanimously approved the Merger and approved and adopted the
Merger Agreement and determined that the Merger is in the best interests of the
Company and its Stockholders. Therefore, the Board of Directors recommends that
the Stockholders vote FOR approval of the Merger and approval and adoption of
the Merger Agreement. See "The Merger--Background of the Merger" and "--The
Company's Reasons for the Merger with T&B; Recommendation of the Board."
 
OPINION OF THE COMPANY'S FINANCIAL ADVISOR
 
  The Company's financial advisor, Houlihan Lokey, has delivered its written
opinion to the Board stating that the merger consideration to be received by
the Stockholders in the Merger is fair from a financial point of view to such
holders. The full text of the written opinion of Houlihan Lokey, which sets
forth information with respect to assumptions made, matters considered and
limitations on the review undertaken in connection with the opinion, is
included in this Proxy Statement as Annex B. Stockholders are urged to, and
should, read such opinion in its entirety. See "The Merger--Opinion of the
Company's Financial Advisor."
 
THE MERGER AND THE MERGER AGREEMENT
 
  Merger Consideration and Merger Consideration Adjustment. Pursuant to the
Merger Agreement, each share of Common Stock issued and outstanding at the
Effective Time (other than shares as to which dissenters' rights are perfected)
will be converted automatically into the right to receive the Per Share Merger
Consideration, which will consist of approximately $3.54 in cash. This figure
is subject to reduction under certain circumstances if and to the extent that
the Company's consolidated stockholders' equity at the end of the month
immediately preceding the month in which the Special Meeting is scheduled to
occur (as set forth in an unaudited balance sheet of the Company as of such
date to be prepared by the Company's independent auditors) is less than
$15,029,000, which was the Company's consolidated stockholders' equity on
August 31, 1998.
 
                                       6
<PAGE>
 
 
  For purposes of adjustment to the Per Share Merger Consideration, there shall
be added to the Company's consolidated stockholders' equity (a) the amount of
the Company's total expenditures (including, without limitation, materials,
labor and overhead) between December 31, 1997 and the date of the unaudited
balance sheet on the construction and repair of machinery and equipment used in
the Company's business that had not been previously capitalized, (b) the fair
market value of inventory held by, but not recorded on the books of, the
Company that was either produced by competitors of the Company or rejected by
the Company's customers, and (c) the total amount of the fees and expenses
incurred through the date of the unaudited balance sheet by the Company in
connection with the Merger, the Merger Agreement and the transactions
contemplated thereby but not to exceed $400,000.
 
  The Company does not believe, based on its current operating results, that
there will be any such reduction in the Merger Consideration. In addition, the
Merger Agreement provides that the Company may terminate the Merger Agreement
without consummating the Merger if the amount of any such reduction in the
Merger Consideration would exceed $1.5 million (approximately $0.26 per share).
See "The Merger--General" and "The Merger Agreement--Merger Consideration
Adjustment."
 
  Treatment of Outstanding Options. All options (both vested and unvested) to
acquire Common Stock granted under the Company's 1995 Stock Option Plan (the
"Option Plan") shall be converted upon the Effective Time into the right to
receive from T&B cash equal to (x) the number of shares of Common Stock
receivable upon exercise of such option multiplied by (y) the excess of the Per
Share Merger Consideration over the per share exercise price of the Common
Stock underlying the option. Every director and officer of the Company (other
than Mr. Bender) holds options under the Option Plan. There are outstanding
options to purchase 155,500 shares of Common Stock under the Option Plan, each
at an exercise price of $2.375. See "The Merger--Interests of Certain Persons
in the Merger."
 
  Effective Time of Merger; Payment for the Common Stock. If the Merger is
approved and the Merger Agreement is approved and adopted by the Stockholders,
the Merger will become effective (the "Effective Time") upon the filing of the
certificate of merger with the Secretary of State of the State of Delaware. It
is anticipated that, subject to the satisfaction or waiver, if permissible, of
the conditions set forth in the Merger Agreement, such filing will be made
promptly after each of the conditions precedent to the consummation to the
Merger have been satisfied or waived.
 
  As promptly as practicable following the Effective Time, an exchange agent to
be designated by T&B in accordance with the Merger Agreement (the "Exchange
Agent") will forward to the holders of certificates formerly evidencing shares
of Common Stock ("Certificates") detailed instructions with regard to the
surrender of such Certificates and a letter of transmittal to accompany any
surrendered Certificates. Payment will be made to such former holders of shares
of Common Stock as promptly as practicable following receipt by the Exchange
Agent of Certificates and other required documents. No interest will be paid or
accrued on the cash payable upon the surrender of Certificates.
 
  STOCK CERTIFICATES SHOULD NOT BE SENT WITH THE ENCLOSED PROXY CARD. IF THE
MERGER IS CONSUMMATED, STOCKHOLDERS WILL BE FURNISHED INSTRUCTIONS FOR
EXCHANGING THEIR SHARES OF COMMON STOCK FOR CASH.
 
  Conditions to the Merger; Regulatory Approvals. The obligations of the
Company, Merger Sub and T&B to consummate the Merger are subject to the
satisfaction or waiver of certain conditions contained in the Merger Agreement,
including obtaining requisite Stockholder approval and the expiration or
termination of the waiting period applicable to the consummation of the Merger
under the HSR Act. On October 29, 1998, the Company and T&B received notice of
the early termination of the waiting period under the HSR Act. Before the
Merger can be consummated, the Company and T&B must have obtained all material
consents and approvals required under certain contracts. In addition, T&B's and
Merger Sub's obligations to consummate the Merger
 
                                       7
<PAGE>
 
are conditioned on Mr. Bender's delivery, in the event that the aggregate
amount of dissenting shares exceeds 20% of the total number of outstanding
shares of Common Stock at the Effective Time, of an agreement obligating him to
reimburse T&B for amounts paid in excess of the Merger Consideration, if any,
in respect of the dissenting shares exceeding 20% of the outstanding shares.
See "The Merger Agreement--Conditions to the Merger" and "--Regulatory
Approvals."
 
  No Solicitation Of Business Combination Proposals; Breakup Fee. The Merger
Agreement prohibits, subject to certain exceptions, Mr. Bender and the Company
and its subsidiaries, officers, employees, representatives and other agents
from directly or indirectly soliciting, initiating or entering into discussions
or transactions or contractual obligations with, or otherwise encouraging third
parties concerning, the acquisition of the Company or its assets. In certain
cases, T&B will have the right to receive a payment of $600,000 (the "Breakup
Fee") if (i) T&B terminates the Merger Agreement after the Company withdraws
its recommendation of the Merger Agreement or the Merger or (ii) the Company's
Board terminates the Merger Agreement in connection with its review of an
unsolicited business combination proposal from a third party which the Board
has determined may be more favorable to Stockholders. See "The Merger
Agreement--No Solicitation of Business Combination Proposals."
 
  Termination. The Merger Agreement may be terminated and the Merger abandoned
prior to the Effective Time, notwithstanding the approval by the Stockholders
at the Special Meeting in certain circumstances, including (i) by mutual
written consent of the parties, (ii) the failure to cure a material breach of a
representation, warranty or covenant within specified time periods, (iii) the
failure of closing conditions to be satisfied by March 31, 1999, (iv) by either
party under certain circumstances, including, among other things, (a) the
Merger has not been consummated by March 31, 1999 (provided that the right to
terminate is not available to any party whose failure to perform any of its
obligations under the Merger Agreement is the cause of or results in the
failure of the Merger to be consummated by March 31, 1999), (b) if, at a
Special Meeting duly convened therefor and finally adjourned, approval of the
holders of the Common Stock of the Merger Agreement and the Merger shall not
have been obtained or (c) if any governmental authority shall have issued a
governmental order or taken any other action permanently enjoining, restraining
or otherwise prohibiting the consummation of the Merger or any of the other
transactions contemplated by the Merger Agreement and such governmental order
or other action shall have become final and nonappealable, (v) by T&B if the
Board of Directors withdraws its recommendation of the Merger Agreement or the
Merger or resolves to do so, in which case the Company must pay T&B the Breakup
Fee, (vi) by the Company if, after receiving an unsolicited proposal for a
business combination, the Board of Directors determines in good faith that such
proposal may be more favorable to the Stockholders than the Merger, provided
that the Company pays T&B the Breakup Fee, or (vii) by the Company if the
adjustments to the purchase price would reduce the aggregate purchase price by
more than $1.5 million. See "The Merger Agreement--Termination."
 
  In the event of termination of the Merger Agreement, the Merger Agreement
shall terminate without any liability or obligations of any party to any other
party, except for (i) T&B's or Merger Sub's ongoing obligations to maintain the
confidentiality of confidential information of the Company, (ii) the Company's
obligation to pay the Breakup Fee under certain circumstances, and (iii) any
liability of a party for a willful breach of the Merger Agreement prior to
termination.
 
  Fees And Expenses. Except for the Company's obligation to pay the Breakup Fee
under certain circumstances, each party to the Merger Agreement will bear its
own costs and expenses incurred in connection with the Merger Agreement and the
consummation of the transactions contemplated thereby (whether or not the
Merger is consummated). See "The Merger Agreement--Termination."
 
  Source and Amount of Funds. If the Merger is consummated, the funds required
to consummate the Merger are expected to be obtained from T&B's cash on hand
and through T&B's existing credit facilities.

INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  Upon the consummation of the Merger, Mr. Bender and T&B will also enter into
an Independent Consulting Agreement which, among other things, provides that
Mr. Bender will be paid $100,000 to act as a consultant for T&B following the
Effective Time for a period of one year (unless extended by express written
agreement of T&B and Mr. Bender). See "The Merger--Interests of Certain Persons
in the Merger."
 
  Under the Merger Agreement, T&B has agreed to guarantee the repayment of
certain loans made to the Company by Mr. Bender and Carlos V. Espinosa, a
director and Vice President of the Company. T&B would only be required to make
payments under the guarantees if the Company did not make payments of principal
or interest on such loans as scheduled. See "The Merger--Interests of Certain
Persons in the Merger."
 
ILAN BENDER'S ESCROW AND NON-COMPETITION COMMITMENT
 
  In connection with the consummation of the Merger, Mr. Bender and a family
partnership which Mr. Bender controls have agreed to place in escrow a portion
of their personal proceeds from the Merger in order to indemnify T&B for losses
related to certain environmental remediation costs. See "The Merger--Ilan
Bender's Escrow and Non-Competition Commitment."
 
ACCOUNTING TREATMENT
 
  The Merger will be treated as a "purchase" for accounting purposes.
 
CERTAIN TAX CONSEQUENCES OF THE MERGER
 
  The receipt of cash for shares of Common Stock in the Merger will be a
taxable transaction for federal income tax purposes and may also be a taxable
transaction under applicable state, local, foreign or other tax laws.
Stockholders are urged to consult their own tax advisors as to the particular
tax consequences of the Merger, including the applicability and effect of
state, local, foreign and other taxes. See "Certain Tax Consequences to
Stockholders."
 
APPRAISAL RIGHTS FOR DISSENTING STOCKHOLDERS
 
  Under Delaware law, Stockholders who follow the required procedures are
entitled to appraisal rights in connection with the Merger. See "The Merger--
Specific Rights of Dissenting Stockholders."
 
MARKET PRICES
 
  Shares of Common Stock are listed and traded on the Nasdaq National Market.
On October 6, 1998, the date preceding public announcement of the execution of
the Merger Agreement, the closing sales price of a share of Common Stock on the
Nasdaq National Market was $1.75. On December 4, 1998, the latest practicable
trading day before the printing of this Proxy Statement, the closing sales
price of a share of Common Stock on the Nasdaq National Market was $3.281.

                              VOTING AND PROXIES
 
  This Proxy Statement is being furnished to Stockholders in connection with
the solicitation of proxies by or on behalf of the Board of Directors for use
at the Special Meeting.
 
RECORD DATE; SOLICITATION OF PROXIES
 
  The close of business on December 4, 1998 has been fixed as the Record Date
for the determination of Stockholders entitled to notice of, and to vote at,
the Special Meeting. As of Record Date, 5,681,000 shares of Common Stock, held
by 48 holders of record, were issued and outstanding and entitled to vote at
the Special Meeting. Holders of shares of Common Stock, or their legal
representatives, are entitled to one vote at the Special Meeting for each
share of Common Stock held of record by them at the Record Date.
 
  In addition to the solicitation of proxies by use of the mails, proxies may
also be solicited by the Company and its directors, officers and employees
(who will receive no additional compensation therefor) by telephone, telegram,
facsimile transmission and other electronic communication methods or personal
interview. The Company will reimburse banks, brokerage houses, custodians and
other fiduciaries who hold shares of Common Stock in their name or custody, or
in the name of nominees for others, for their out-of-pocket expenses incurred
in forwarding copies of the proxy materials to those persons for whom they
hold such shares. The Company will bear the costs of the Special Meeting and
of soliciting proxies therefor.
 
VOTING OF PROXIES; VOTE REQUIRED
 
  A majority of the outstanding shares of Common Stock entitled to vote as of
the Record Date, represented in person or by proxy, is required for a quorum
at the Special Meeting. The affirmative vote of a majority of the outstanding
shares of Common Stock as of the Record Date is required for approval of the
Merger and approval and adoption of the Merger Agreement. Abstentions may be
specified with respect to the approval and adoption of the Merger Agreement
and will be counted as present for the purpose of determining the existence of
a quorum but will have the effect of a negative vote due to the requirement of
affirmative votes described in the preceding sentence.
 
  Under the terms of the Merger Agreement, Mr. Bender, who beneficially holds,
on behalf of himself and a family partnership over which he has voting
control, approximately 54% of the outstanding shares of Common Stock, has
agreed to vote his shares in favor of approval of the Merger and approval and
adoption of the Merger Agreement at the Special Meeting. Therefore, assuming
such shares are so voted, the Merger will be approved and the Merger Agreement
will be approved and adopted without any action on the part of any other
Stockholder. See "The Merger Agreement--The Majority Stockholder."
 
  Shares of Common Stock which are represented by properly executed proxies,
unless such proxies shall have previously been properly revoked, will be voted
in accordance with the instructions indicated in such proxies. If no contrary
instructions (including votes against or abstentions) are indicated, such
shares will be voted FOR approval of the Merger and approval and adoption of
the Merger Agreement, and in the discretion of the persons named in the proxy
as proxy appointee as to any other matter which may properly come before the
Special Meeting.
 
  While brokers who hold shares of Common Stock in "street name" have the
authority to vote on certain items when they have not received instructions
from beneficial owners, brokers will not be entitled to vote on the Merger
Agreement absent instructions. Shares of Common Stock held by brokers who do
not receive instructions but which are reported as "instructions withheld"
will be treated as present, in person or by proxy, at the Special Meeting and
counted as present for quorum purposes. A failure by a broker to vote will
have the effect of a negative vote on the approval of the Merger and approval
and adoption of the Merger Agreement.
 
  It is not expected that any matters other than those referred to in this
Proxy Statement will be brought before the Special Meeting. If, however, other
matters are properly presented, including, among other things, a motion
 
                                      10
<PAGE>
 
to adjourn or postpone the Special Meeting to another time and/or place for
the purpose of, among other things, soliciting additional proxies in favor of
approval of the Merger and approval and adoption of the Merger Agreement, one
or more of the persons named as proxy appointees will vote in accordance with
their best judgment on such matters and consistent with the voting rights of
such shares as provided by the Company's By-Laws and the DGCL; provided,
however, that no proxy that is voted or is treated as voted against approval
of the Merger and approval and adoption of the Merger Agreement will be voted
in favor of any adjournment or postponement for the purpose of soliciting
additional proxies. At any subsequent reconvening of the Special Meeting, all
proxies will be voted in the same manner as such proxies would have been voted
at the original convening of the Special Meeting, except for proxies that have
been effectively revoked prior to such reconvened meeting. The grant of a
proxy will also confer discretionary authority on the persons named in the
proxy to vote in accordance with their best judgment on matters incident to
the conduct of the Special Meeting.
 
  Any Stockholder may revoke a proxy at any time before it is voted by filing
with the Secretary of the Company, at the executive offices of the Company, an
instrument revoking the proxy or by returning a duly executed proxy bearing a
later date, or by attending the Special Meeting and voting in person. Any such
filing should be sent to 14538 Keswick Street, Van Nuys, California 91405,
Attention: Secretary. Attendance at the Special Meeting will not by itself
constitute revocation of a proxy.
 
  As promptly as practicable following the Effective Time, the Exchange Agent
will forward to the holders of Certificates formerly evidencing shares of
Common Stock detailed instructions with regard to the surrender of such
Certificates and a letter of transmittal to accompany any surrendered
Certificates. Payment will be made to such former holders of shares of Common
Stock as promptly as practicable following receipt by the Exchange Agent of
Certificates and other required documents. No interest will be paid or accrued
on the cash payable upon the surrender of Certificates.
 
  STOCK CERTIFICATES SHOULD NOT BE SENT WITH THE ENCLOSED PROXY CARD. IF THE
MERGER IS CONSUMMATED, STOCKHOLDERS WILL BE FURNISHED INSTRUCTIONS FOR
EXCHANGING THEIR SHARES OF COMMON STOCK FOR CASH.

                                  THE MERGER
 
  The following information with respect to the Merger is qualified in its
entirety by reference to the complete text of the Merger Agreement, a copy of
which is included in this Proxy Statement as Annex A. The following
information includes a summary of the material terms of the Merger Agreement,
which sets forth the terms and conditions upon which the Merger is to be
effected. If the Merger is approved and the Merger Agreement is approved and
adopted by the requisite vote of Stockholders at the Special Meeting, and all
other conditions to the obligations of the parties thereto are satisfied or
waived, the Merger will be consummated and Merger Sub will merge with and into
the Company at the Effective Time. The Company will be the surviving
corporation (the "Surviving Corporation") in the Merger, but will become a
wholly-owned subsidiary of T&B. STOCKHOLDERS ARE URGED TO READ THE MERGER
AGREEMENT IN ITS ENTIRETY FOR A MORE COMPLETE DESCRIPTION OF THE MERGER.
 
GENERAL
 
  Pursuant to the Merger Agreement, each share of Common Stock issued and
outstanding at the Effective Time (other than shares as to which dissenters'
rights are perfected) will be converted automatically into the right to
receive the Per Share Merger Consideration, which will consist of $3.54 in
cash, subject to reduction under certain circumstances if and to the extent
that the Company's consolidated stockholders' equity at the end of the month
immediately preceding the month in which the Special Meeting is scheduled to
occur (as set forth in an unaudited balance sheet of the Company as of such
date to be prepared by the Company's independent auditors) is less than
$15,029,000, which was the Company's consolidated stockholders' equity on
August 31, 1998. As a result of the Merger, holders of shares of Common Stock
will cease to have an equity interest in, or possess any rights as
Stockholders of, the Surviving Corporation. See "The Merger Agreement--Merger
Consideration Adjustment."
 
  A majority of the outstanding shares of Common Stock entitled to vote,
represented in person or by proxy, is required for a quorum at the Special
Meeting. The affirmative vote of the holders of a majority of the outstanding
shares of Common Stock as of the Record Date is required to approve the Merger
and approve and adopt the Merger Agreement. For purposes of determining
whether the Merger has been approved and the Merger Agreement approved and
adopted, abstentions and broker non-votes will be treated as votes against the
proposal.
 
  Under the terms of the Merger Agreement, Mr. Bender, who beneficially holds,
on behalf of himself and a family partnership over which he has voting
control, approximately 54% of the outstanding shares of Common Stock, has
agreed to vote his shares in favor of approval of the Merger and approval and
adoption of the Merger Agreement at the Special Meeting. Therefore, assuming
such shares are so voted, the Merger will be approved and the Merger Agreement
will be approved and adopted without any action on the part of any other
Stockholder. See "The Merger Agreement--The Majority Stockholder."
 
BACKGROUND OF THE MERGER
 
  During the past four years, the Company has made numerous overtures to
Robroy Industries, Inc. ("Robroy"), another manufacturer of PVC-coated steel
conduit and fittings, in an effort to purchase Robroy's Conduit Division.
During the same period, the Company has made numerous overtures to Permacote
Industries, also a manufacturer of PVC-coated conduit and fittings, in an
effort to purchase Permacote. In response to each of these overtures, both
Permacote and Robroy advised the Company that they were not willing to sell
their conduit businesses to the Company.
 
  On March 24, 1998, T&B, through one of its outside business advisors, sent a
letter to the Company expressing a possible interest in acquiring the Company.
 
                                      12
<PAGE>
 
  In or around early April 1998, Robroy orally communicated a possible
interest in acquiring the Company for $15 million cash (equating to
approximately $2.63 per share of the Company's Common Stock). The Company
advised Robroy that the Company would not be willing to do a transaction at
that price.
 
  On April 30, 1998, three T&B executives visited the Company's manufacturing
facility in Mobile, Alabama. The three T&B executives advised the Company
that, if T&B were interested in acquiring the Company, T&B would send a
written offer to the Company.
 
  In or around the middle of May, 1998, Robroy orally communicated a possible
interest in acquiring the Company for $17.1 million cash (equating to
approximately $2.99 per share of the Company's Common Stock). The Company
advised Robroy that the Company would not be willing to do a transaction at
that price.
 
  On May 27, 1998, T&B provided the Company with a letter expressing a
possible interest in acquiring the Company for $15 million of T&B's Common
Stock (equating to approximately $2.63 per share of the Company's Common
Stock). The Company advised T&B that the Company would not be willing to do a
transaction at that price.
 
  On May 28, 1998, T&B orally communicated to the Company that, if T&B elected
to acquire the Company, T&B would be willing to increase its purchase price
for the Company from $15 million of T&B's Common Stock (equating to
approximately $2.63 per share of the Company's Common Stock) to an amount of
T&B's Common Stock equal to $17.8 million plus the increase in the Company's
stockholders' equity between December 31, 1997 and the closing date of such
transaction. Assuming a closing date of around September 30, 1998, the Company
anticipated that T&B's purchase price, after taking into account the increase
in stockholders' equity, would be an amount of T&B's Common Stock equal to
approximately $18.9 million (equating to approximately $3.30 per share of the
Company's Common Stock).
 
  On June 2, 1998, the Company signed a non-binding letter agreement with T&B
granting T&B a 45-day exclusive right to conduct due diligence and negotiate
with the Company concerning an acquisition (the "T&B Letter Agreement"). The
T&B Letter Agreement also contained a non-binding proposal for T&B to acquire
the Company for an amount of T&B's Common Stock equal to $17.8 million plus
the increase in the Company's stockholders' equity between December 31, 1997
and the closing date of such transaction. As described above, the Company
anticipated that this would equate to approximately $18.9 million (equating to
approximately $3.30 per share of the Company's Common Stock). The closing
market price of the Company's Common Stock on June 2, 1998 was $2.563 per
share.
 
  On June 4, 1998, prior to the commencement of T&B's due diligence, the
Company sent a letter to T&B concerning certain accounting adjustments that
the Company expected to be added to the Company's closing stockholders' equity
for purposes of determining T&B's purchase price.
 
  On June 5, 1998, Robroy sent to the Company an unsolicited letter expressing
interest in acquiring the Company for a total of $21.45 million cash, $20.0
million of which would be payable to the Company's Stockholders (equating to
approximately $3.49 per share of the Company's Common Stock), and $1.45
million of which would be paid over five years to Mr. Bender and other
executives of the Company in exchange for executing five-year non-competition
agreements. Robroy also indicated in its letter that its purchase price was
based upon the Company's March 31, 1998 balance sheet. Robroy also indicated
in its letter that Robroy would require that a portion of its purchase price
(unspecified) be placed in escrow to cover existing and potential
environmental problems, defective or obsolete inventory, and claims and
liabilities arising from pre-closing events and circumstances. Because the
exclusivity provisions of the T&B Letter Agreement precluded the Company from
discussing a transaction with a third party at that time, the Company
indicated to Robroy that the Company would respond to Robroy's proposal after
August 14, 1998, the date of the Company's next scheduled Board meeting.
 
                                      13
<PAGE>
 
  During June and July of 1998, representatives of T&B engaged in due
diligence investigations of the Company's business and properties, including
environmental testing at the Company's Mobile property by T&B's environmental
consultant.
 
  On June 30, 1998, T&B received a report from its environmental consultant
indicating that contamination was present at the Company's Mobile property and
suggesting that remediation costs could approximate $3.4 million. After
receipt of the preliminary report, T&B informed the Company that, in light of
the potential environmental problems at the Company's Mobile property, T&B
would only proceed with its acquisition of the Company if the Company agreed
to a $3.4 million downward adjustment of T&B's purchase price or if the
Company could provide T&B with an alternative solution to the environmental
problem that was satisfactory to T&B. The Company believed that the
remediation estimates of T&B's consultant were excessive. The Company
proceeded to hire its own environmental consultant to make an independent
determination of the extent of any environmental problem and the cost of
remediation.
 
  During the remainder of July 1998, the Company's environmental consultant
reviewed the findings of T&B's environmental consultant and conducted its own
environmental investigation. During that time, T&B and the Company held
various discussions in which T&B indicated that it might require that a
portion of the purchase price for the Company be placed in escrow to cover
potential environmental liabilities at Mobile. Also during that time, the
respective attorneys for the Company and T&B began negotiating the terms of a
definitive merger agreement.
 
  On July 17, 1998, the exclusivity period under the T&B Letter Agreement
expired. At that time, T&B's environmental concerns remained and T&B was still
not willing to consummate a transaction without a $3.4 million downward
adjustment in T&B's purchase price. The Company contacted Robroy to pursue
discussions concerning the possible acquisition of the Company by Robroy.
 
  In a letter dated July 24, 1998, T&B requested that the Company extend the
exclusivity period under the T&B Letter Agreement until August 24, 1998.
 
  On July 26, 1998, Mr. Bender and Peter McIlroy II, the Chairman of the
Board, Chief Executive Officer and President of Robroy, met at JFK Airport in
New York, accompanied by their respective attorneys, to discuss a possible
acquisition of the Company by Robroy. At that meeting, the Company advised
Robroy that the Company had received a proposal from a Fortune 500 company
which, at the time, was lower than the current Robroy proposal, but which
could change at any time. The Company further pointed out to Robroy that
Robroy suffered from a disadvantage that the Fortune 500 company did not
suffer from. The Company advised Robroy that the disadvantage was that a
transaction with Robroy could suffer antitrust-related regulatory delays or
other impediments since Robroy was a competitor of the Company whereas the
Fortune 500 company was not. In order to expedite antitrust review, the
Company and Robroy decided to prepare and file as soon as possible pre-merger
notification forms under the HSR Act concerning a transaction between the
Company and Robroy. Other issues discussed at the meeting included the
purchase price and certain concerns Robroy had regarding the Company's
inventory. With respect to Robroy's request for non-competition agreements
from certain of the Company's key employees, Mr. Bender advised Robroy that,
while he could not speak for the other key employees of the Company, he would
provide Robroy with the requested non-competition agreement without any
additional compensation. Mr. Bender requested that Robroy pay all of the money
that Robroy proposed paying to Mr. Bender for the non-competition agreement to
all of the Company's Stockholders instead in order to increase the purchase
price of their stock.
 
  On July 28, 1998, attorneys for the Company informed T&B that the Company
had received a higher offer from Robroy and therefore could not extend T&B's
exclusivity, which had expired prior to T&B's request for an extension. They
indicated to T&B that the Company was going to permit Robroy to conduct its
due diligence review. During that conversation, the Company's attorneys also
indicated that the Company would not enter into a transaction with T&B unless
T&B dropped its request for an environmental escrow relating to what T&B
believed was a $3.4 million environmental issue. Over the next week, there
were numerous follow-up conversations between the Company and T&B on these
issues.

  On August 5, 1998, the Company's environmental consultant issued its site
assessment report in which it informed the Company that, if remediation was
required, its estimate of the cost of implementing the potential remediation
technologies for soil and ground water was approximately $200,000 to $450,000
to be incurred over approximately a two-year period, instead of the $3.4
million estimated by T&B's environmental consultant. The Company's consultant
also recommended that the Alabama Department of Environmental Management be
notified. The written report of the Company's environmental consultant was
delivered to the Company on August 5, 1998, and to T&B on August 7, 1998.
 
  On August 13, 1998, in connection with the HSR Act filings, the Company and
Robroy signed a non-binding letter outlining the basic terms of a possible
transaction structure and identifying certain significant issues (including
purchase price) that would need to be agreed upon. On that date, the Company
and Robroy also signed a confidentiality agreement in order to enable Robroy
to commence its due diligence investigation of the Company. The Company and
Robroy filed their respective pre-merger notification forms with the Federal
Trade Commission and the Department of Justice on August 14, 1998.
 
  During mid- and late-August, 1998, the Company provided Robroy with due
diligence materials, including the environmental report issued by the
Company's consultant concerning the Mobile property. At the same time, the
Company continued to negotiate separate definitive merger agreements with T&B
and Robroy. During this period, T&B changed its proposal to an all-cash
transaction. T&B had still not committed to a specific purchase price, and T&B
requested that $1.0 million of Mr. Bender's personal proceeds from the sale of
the Company be placed in escrow for an unspecified period of time to indemnify
T&B for any breaches of representations and warranties generally. During this
period, T&B had not consented to the accounting adjustments for purposes of
determining the purchase price that the Company advised T&B the Company was
expecting in the letter that the Company sent to T&B on June 4, 1998, and T&B
continued to express concerns regarding potential environmental liabilities at
the Mobile property.
 
  On August 21, 1998, Robroy verbally communicated to the Company that, on
account of potential environmental liabilities at the Company's Mobile
facility, Robroy was lowering its proposed total purchase price by $450,000,
to $21.0 million. Of this amount, Robroy proposed that $19.8 million would be
paid to the Company's Stockholders in cash (equating to approximately $3.46
per share of the Company's Common Stock), and $1.2 million would be paid to
Mr. Bender and other executives of the Company in exchange for five-year non-
competition agreements. Robroy also requested that it be allowed to conduct
additional testing at the Mobile property to assess further the extent of any
environmental contamination. The Company continued to take the position with
Robroy that a $450,000 adjustment for the environmental issue was too high.
 
  On September 4, 1998, Mr. Bender met with T&B executives at T&B's
headquarters in Memphis, Tennessee to discuss various operational and business
issues relating to a T&B acquisition of the Company.
 
  On September 10, 1998, the Company's Board engaged Houlihan Lokey to advise
it regarding the fairness, from a financial point of view, of either a Robroy
or T&B transaction to the Company's Stockholders.
 
  On September 11, 1998, the Company delivered to T&B financial projections
indicating a projected increase in the Company's stockholders' equity between
December 31, 1997 and November 30, 1998 of approximately $1.4 million, which
would result in a purchase price payable by T&B of approximately $19.2
million, before the accounting adjustments requested by the Company, and
approximately $20.12 million if the Company was given credit for all such
accounting adjustments (which the Company estimated at $918,000).
 
  On September 13, 1998, 30 days after the Company and Robroy filed their pre-
merger notification forms, the waiting period under the HSR Act with respect
to Robroy's acquisition of the Company expired.
 
  On September 14, 1998, the Company delivered to Robroy similar projections,
and requested that Robroy raise its purchase price by the amount of any
increase in the Company's stockholders' equity between March 31,
 
                                      15
<PAGE>
 
1998 and closing, projected to be approximately $1 million, since Robroy
indicated in its June 5, 1998 letter that its purchase price was based upon
the Company's March 31, 1998 balance sheet. Robroy responded by stating the
reference to its offer being based upon the Company's March 31, 1998 balance
sheet was intended to provide a downward adjustment in price if the Company's
balance sheet worsened, but not an upward adjustment in price if the Company's
balance sheet improved. Throughout these discussions, Robroy reiterated that
its proposed purchase price would remain at $19.8 million for the Company's
Stockholders and $1.2 million allocable to non-competition agreements.
Throughout these discussions, Mr. Bender reiterated to Robroy that he would
execute the requested non-competition agreement without any additional
consideration and that Robroy should instead pay the $500,000 that Robroy
proposed to pay him for his non-competition agreement to the
Company's Stockholders.
 
  On September 16, 1998, Robroy insisted for the first time that, before
signing a definitive merger agreement, it be permitted to conduct a walk-
through of the Company's Mobile facility in order to conduct a physical
inspection of the Company's inventory for valuation purposes. Robroy indicated
that, to the extent the inventory review revealed problems with the inventory
as determined by Robroy, it would downward adjust its purchase price for the
Company. The Company attempted to address Robroy's concern by providing Robroy
with a written report which contained a detailed breakdown of all of the
Company's inventory. Notwithstanding the written report, Robroy advised the
Company that Robroy would not sign a definitive merger agreement before
conducting a walk-through of the Company's Mobile facility in order to conduct
a physical inspection of the Company's inventory for valuation purposes,
reserving the right to downward adjust its purchase price for the Company
following the walk-through.
 
  Between September 17, 1998 and September 30, 1998, the Company continued to
negotiate separate definitive merger agreements with T&B and Robroy. The
Company continued to be concerned that if Robroy inspected the Company's
Mobile facility but ultimately did not consummate a transaction with the
Company, Robroy might acquire information concerning the Company's inventory,
processes and technology which would place the Company at a competitive
disadvantage. Due to these concerns, the Company suggested to Robroy various
alternatives to such an inspection, including, among other things, permitting
Robroy's outside accountants to conduct a physical inventory at the Mobile
facility. Robroy rejected all of these suggestions, while continuing to insist
on Robroy's inspection of the Company's Mobile facility. In a further effort
to resolve the impasse over this issue, the Company proposed for Robroy to
deposit the sum of $1 million into an escrow which Robroy would forfeit to the
Company if, after Robroy's inspection of the Company's Mobile facility, Robroy
refused to consummate a transaction at Robroy's proposed purchase price.
Robroy also rejected that proposal. Discussions between the Company and Robroy
also focused on various proposed purchase price adjustments, including
handling the environmental issue through an escrow of $450,000, which was in
addition to Robroy's proposed purchase price.
 
  During a conversation held on September 24, 1998, Mr. Bender asked Mr.
McIlroy to provide the Company with Robroy's highest offer, and Mr. McIlroy
responded that Robroy would not increase its proposed price.
 
  On September 25, 1998, Robroy proposed that, in lieu of any environmental
escrow, the price payable to the Company's Stockholders be reduced by $300,000
to $19.9 million (equating to approximately $3.47 per share of the Company's
Common Stock).
 
  On September 30, 1998, Robroy advised the Company that, prior to executing
any binding agreement, the Company would be required to provide Robroy with
certain information regarding the Company's sales, costs and inventory which
the Company viewed as competitively sensitive and which the Company previously
advised Robroy would not be made available to Robroy until after Robroy
executed a binding agreement.
 
  On September 25, 1998, the Company, T&B and their respective attorneys held
a conference call in which the Company informed T&B of the higher Robroy offer
and the material terms thereof and asked T&B to raise its offer. T&B responded
that it would need several days to evaluate the Company's request. The Company
asked
 
                                      16
<PAGE>
 
that T&B respond prior to October 1, 1998, which was when the Company's Board
had scheduled a meeting to review the discussions with T&B and Robroy. Between
September 25 and 28, 1998, the Company, T&B and their representatives held
various follow-up calls in which valuation issues were discussed.
 
  On September 29, 1998, T&B delivered to the Company a revised proposal in
which T&B increased its proposed purchase price to $20.3 million in cash
(equating to approximately $3.54 per share of the Company's Common Stock).
 
  On October 1, 1998, the Company's Board held a special meeting to discuss
the status and terms of the respective proposed merger agreements with T&B and
Robroy. The Board took note of the significant contingencies associated with
the Robroy proposal, including the continuing risks of non-consummation (and
the attendant harm to the Company's business from a failed transaction with a
competitor) due to possible antitrust-related impediments, and Robroy's
demands for a pre-signing physical inventory at the Company's Mobile facility
and pre-signing review of certain competitively sensitive documents--demands
which effectively left Robroy's proposal subject to a possible downward
adjustment in purchase price or withdrawal altogether. The Board determined
that, in order for it to consider further a transaction with Robroy in view of
the existing T&B proposal, Robroy would need to increase its proposed purchase
price, eliminate any further contingencies to executing a binding agreement,
and take into account the risks to the Company of the possible antitrust-
related regulatory impediments so that the Board could evaluate the two
proposals on a comparable basis.
 
  At the Board's instructions, after the Board meeting on October 1, 1998, Mr.
Bender and the Company's attorneys notified Robroy's attorneys that the
Fortune 500 company had raised its offer and it was now higher than Robroy's
proposal and that, in order to proceed on a basis that the Company's Board
would view favorably, Robroy must submit to the Company its highest and best
offer which had to include an increased purchase price, an elimination of any
further contingencies to executing a binding agreement (including the pre-
signing physical inventory and review of competitively sensitive documents),
and take into account the risks to the Company of the possible antitrust-
related impediments. Robroy was asked to submit its revised proposal in
writing by the close of business on October 2, 1998. Robroy's attorneys
advised the Company that they understood what Robroy needed to do in order for
the Company's Board to review Robroy's revised proposal favorably but that
they were not optimistic that Robroy would meet the Board's conditions in
light of their importance to Robroy.
 
  On October 2, 1998, Robroy sent a response letter to the Company proposing
to increase the transaction consideration to $21.95 million, $21.7 million
(equating to approximately $3.78 per share of the Company's Common Stock) of
which would be payable to the Company's Stockholders and $250,000 of which
would be payable to Mr. Bender over five years for a non-competition
agreement. The proposal also required that $450,000 of the consideration
payable to the Company's Stockholders be held in a two-year escrow to cover
certain environmental liabilities at the Company's Mobile facility. In the
letter, Robroy continued to insist on a pre-signing physical inventory at the
Mobile facility and, while Robroy indicated a willingness to narrow its
request to review competitively sensitive documents, it did not withdraw that
demand. The letter also contained a requirement that the Company execute and
deliver, no later than the close of business on October 6, 1998 (prior to
Robroy's physical inventory review, document review and the execution of a
definitive acquisition agreement), a binding commitment to pay Robroy a
breakup fee of $500,000 in the event that discussions terminated under certain
circumstances.
 
  On October 5, 1998, Mr. Bender met with various T&B executives at T&B's
Memphis headquarters to discuss certain operational and customer issues that
would need to be addressed following the execution of a binding agreement. At
that meeting, Mr. Bender informed T&B that Robroy had raised its offer and
asked T&B to raise its offer in response. T&B advised Mr. Bender that it was
unwilling to raise its price any further.
 
  On October 6, 1998, the Company's Board held a special meeting to review
Robroy's revised proposal and T&B's revised definitive merger agreement. In
evaluating Robroy's proposal, the Board noted that Robroy's proposed purchase
price for the Company's Stockholders was $21.7 million (not counting the
$450,000 environmental escrow), versus the $20.3 million offered by T&B. On
the other hand, the Board noted that, unlike T&B, which was prepared to enter
into a definitive and binding agreement immediately, Robroy had not yet
 
                                      17
<PAGE>
 
committed to enter into a definitive binding agreement and would not do so
unless and until Robroy conducted a physical inspection of the Company's
inventory at the Company's Mobile facility and Robroy reviewed certain of the
Company's competitively sensitive information. In addition, the Board viewed
as inappropriate Robroy's request for a $500,000 breakup fee prior to Robroy
having signed a definitive and binding agreement. The Board believed that the
Company would suffer significant competitive harm if Robroy was allowed to
conduct a physical inspection of the Company's inventory at the Company's
Mobile facility and review certain of the Company's competitively sensitive
information and subsequently not enter into a definitive and binding agreement
to consummate a transaction with the Company or subsequently reduce Robroy's
proposed purchase price. The Board also believed that, due to the
contingencies in Robroy's proposal, it was uncertain that Robroy would
ultimately enter into a definitive and binding agreement with the Company at
Robroy's proposed price, or at any price acceptable to the Company. The Board
also noted the possible antitrust-related impediments to consummating a
transaction with Robroy. In addition, Mr. Bender indicated that, under the
current terms, conditions and contingencies still outstanding with Robroy's
proposal, he would not be willing to execute the shareholder voting agreement
that Robroy was requiring him to execute as part of any definitive and binding
agreement. The Board concluded that entering into the Merger Agreement with
T&B, which provided for Per Share Merger Consideration of approximately 102%
greater than the Company's closing stock price on such date and well above
Houlihan Lokey's valuation of the Company in its fairness opinion, was the
best strategy for maximizing the value of the Company for its Stockholders.
 
  At the October 6, 1998 Board meeting, Houlihan Lokey delivered its opinion
that the T&B proposal was fair to the Company's Stockholders from a financial
point of view. At the October 6, 1998 Board meeting, the Company's Board voted
unanimously to approve the Merger Agreement with T&B. Following the October 6,
1998 Board meeting, the Company advised T&B that it was accepting the T&B
offer and both T&B and the Company executed the Merger Agreement.
 
THE COMPANY'S REASONS FOR THE MERGER WITH T&B; RECOMMENDATION OF THE BOARD
 
  On October 6, 1998, the Company's Board, by unanimous vote, approved the
Merger Agreement and the transactions contemplated thereby (including the
Merger) as being in the best interests of the Company and its Stockholders and
decided to recommend adoption of the Merger Agreement and the transactions
contemplated thereby to the Stockholders. In reaching these conclusions, the
Board considered, among others, the following factors:
 
 .  The value to the Company's Stockholders of the continuation of the Company
   as an independent entity versus a strategic combination with T&B pursuant
   to the Merger. Due to increased competition from other types of electrical
   conduit in the market, it has been more difficult for manufacturers of PVC
   coated rigid steel conduit, elbows, and fittings, including the Company, to
   increase sales. As a result, the Company has experienced significant
   pressure on its unit prices, net sales and gross margins. The Company's net
   sales were $24.9 million, $25.0 million and $24.3 million during the fiscal
   years ended December 31, 1995, 1996 and 1997, respectively. The Company's
   gross margins declined from $8.2 million (33.1% of net sales) during 1995
   to $6.7 million (27.4% of net sales) during 1997. The Board believes these
   competitive pressures will continue. The Board also believes that, in order
   to maximize Stockholder value, the Company most likely would be required to
   either diversify its product offerings through acquisitions or pursue a
   sale of the Company. The Board determined that it was in the best interests
   of the Company's Stockholders to afford Stockholders the immediate
   opportunity to maximize the value of their investment pursuant to the
   Merger, rather than pursuing a more uncertain path of long-term growth
   through acquisitions.
 
 .  A comparison of the historical market prices of the Company's Common Stock
   with the Per Share Merger Consideration. Based on the closing market prices
   of Common Stock on October 6, 1998 (the last trading day immediately prior
   to the public announcement of the Merger), the value of the Per Share
   Merger Consideration that would have been received by the Company's
   Stockholders in exchange for their Common Stock pursuant to the Merger if
   it had occurred on such date would have represented a premium of 102% above
   the then-current market price of the Common Stock. The Per Share Merger
   consideration to
 
                                      18
<PAGE>
 
   be paid to the Stockholders also exceeds the highest closing market price
   that the Common Stock has achieved at any time after June 4, 1997 and
   before the date of the first public announcement of the Merger.
 
 .  A limited number of other potential purchasers of the Company. The Board
   believes that, due to slow growth in demand for PVC-coated rigid steel
   conduit and the competitive pressures from other types of conduit, there is
   a limited number of potential purchasers of the Company. The Board
   determined that, if the Company did not consummate a transaction with T&B
   or Robroy, it might not be possible to locate another potential acquiror
   for an extended period of time. The Board noted that, prior to the
   Company's discussions with T&B and Robroy during 1998, the Company had not
   been approached by a serious interested purchaser since 1994.
 
 .  The terms and conditions of the Merger Agreement and related matters,
   including the Per Share Merger Consideration, closing conditions,
   termination rights, termination fees, and the cash-out of the Company's
   stock options, all of which were the product of arms' length negotiations
   in which the Company was assisted by its counsel, Irell & Manella LLP.
 
 .  A comparison of the terms and conditions of the Merger Agreement with those
   contained in Robroy's proposal. The Board also considered the significant
   contingencies and conditions associated with the Robroy proposal, and the
   attendant harm to the Company that would result if a Robroy transaction was
   not consummated. The Board also considered the risks to the Company of the
   possible antitrust-related regulatory impediments of a transaction with
   Robroy. The Board also noted the support that Mr. Bender, who directly and
   through a controlled entity controls 54% of the outstanding shares of the
   Company's Common Stock, demonstrated for the Merger through his willingness
   to agree to vote such shares in favor of the adoption of the Merger
   Agreement. The Board also noted that the terms and conditions of
   Mr. Bender's voting agreement, which is contained in the Merger Agreement,
   significantly enhances the likelihood of the consummation of the Merger.
 
 .  The financial analyses presented by Houlihan Lokey, as well as the written
   opinion of Houlihan Lokey to the effect that, based upon and subject to
   various considerations set forth in such opinion, as of October 6, 1998,
   the Per Share Merger Consideration pursuant to the Merger Agreement is fair
   to the holders of Common Stock from a financial point of view. See "Opinion
   of the Company's Financial Advisor."
 
  The foregoing discussion of the information and factors considered by the
Board is not intended to be exhaustive, but includes all material factors
considered by the Board. In reaching its determination to approve the Merger
Agreement and the transactions contemplated thereby, the Board did not assign
any relative or specific weights to the various factors considered by it nor
did it specifically characterize any factor as positive or negative (except as
described above), and individual directors may have given different weights to
different factors and may have viewed certain factors more positively or
negatively than others.
 
  For the reasons described above, the Board unanimously recommends that the
holders of the Company's Common Stock vote FOR approval of the Merger
Agreement.
 
OPINION OF THE COMPANY'S FINANCIAL ADVISOR
 
  The Company engaged Houlihan Lokey to render an opinion to the Board as to
whether the consideration to be received by the Stockholders of the Company in
connection with the Merger is fair to them from a financial point of view.
Houlihan Lokey is a nationally recognized investment banking firm that is
continually engaged in providing financial advisory services in connection
with mergers and acquisitions, leveraged buyouts, business valuations for a
variety of regulatory and planning purposes, recapitalizations, financial
restructurings, and private placements of debt and equity securities. Houlihan
Lokey has no material prior relationship with the Company or its affiliates.
Houlihan Lokey has been retained by T&B's legal counsel on T&B's behalf in
connection with a matter unrelated to the Merger.
 
  Houlihan Lokey was first contacted by the Company on or about June 5, 1998
and was retained pursuant to a retainer agreement dated September 10, 1998 to
act as financial advisor to the Board. As compensation to Houlihan Lokey for
its services in connection with the Merger, the Company has agreed to pay
Houlihan Lokey
 
                                      19
<PAGE>
 
a fee of $60,000 plus reasonable out of pocket expenses. No portion of
Houlihan Lokey's fees were contingent upon the successful completion of the
Merger. The Company has also agreed to indemnify Houlihan Lokey and related
persons against certain liabilities, including liabilities under Federal
securities laws, arising out of the engagement of Houlihan Lokey, and to
reimburse Houlihan Lokey for certain expenses.
 
  Houlihan Lokey did not, and was not requested by the Company, to make any
recommendations as to the form or amount of consideration to be paid to the
Company's stockholders in connection with the Merger. In arriving at its
opinion, Houlihan Lokey made its determination as to the fairness, from a
financial point of view, of the consideration to be received by the
stockholders of the Company in connection with the Merger on the basis of the
analyses described below. No restrictions or limitations were imposed by the
Company upon Houlihan Lokey with respect to its investigation made or the
procedures followed by Houlihan Lokey in rendering its opinion.
 
  At the special meeting of the Board held on October 6, 1998, Houlihan Lokey
rendered its oral opinion, and subsequently confirmed such opinion in writing
on the same date (the "Fairness Opinion"). A copy of the Fairness Opinion,
which sets forth the assumptions made, the matters considered and certain
limitations on the scope of review undertaken by Houlihan Lokey, is attached
to this Proxy Statement as Annex B. The summary of the Fairness Opinion set
forth in this Proxy Statement is qualified in its entirety by reference to the
full text of the Fairness Opinion attached hereto as Annex B.
 
  In arriving at its opinion, Houlihan Lokey made such reviews, analyses and
inquiries as it deemed necessary and appropriate under the circumstances.
Among other things, Houlihan Lokey (i) reviewed the Company's audited
financial statements for the five fiscal years ended December 31, 1997 and
unaudited financial statements for the quarters ended June 30, 1998, March 31,
1998 and June 30, 1997; (ii) reviewed the Company's unaudited internal
consolidated financial statements for the eight month period ended August 31,
1998, which the Company's management has identified as being the most
currently available financial statements available as of the date of the
valuation date; (iii) met with certain members of the senior management of the
Company to discuss the operations, financial condition, future prospects and
projected operations and historical performance of the Company; (iv) visited
the Company's manufacturing plant in Mobile on September 17, 1998; (v)
reviewed projections prepared by the Company's management with respect to the
Company for the years ending December 31, 1998 and December 31, 1999 (see "--
Certain Financial Projections of the Company"); (vi) reviewed the historical
market prices and trading volume for the Company's publicly trades securities;
(vii) reviewed certain other publicly available financial data for certain
companies we deemed comparable to the Company, and publicly available prices
and premiums paid in other transactions that we considered similar to the
Transaction; (viii) reviewed the September 30, 1998 draft of the Agreement and
Plan of Merger among Thomas & Betts Corporation, Ocal Acquisition Corp., the
Company and certain Stockholders of the Company; (ix) reviewed the September
29, 1998 draft of the proposed Agreement and Plan of Merger among the Company,
Robroy Industries, Inc. and Excelsior Acquisition, Inc.; (x) reviewed a letter
dated October 2, 1998 conveying a revised proposal from Robroy Industries,
Inc. and; (xi) conducted such other studies, analyses, and inquiries as
Houlihan Lokey has deemed appropriate.
 
  Houlihan Lokey used three methodologies to assess the fairness of the Merger
from a financial point of view. Each methodology provided an estimate as to
the value of the Company.
 
  One methodology, the COMPARABLE MARKET MULTIPLE APPROACH, considered the
capitalization multiples for certain income and cash flows of a peer group of
companies and then applied selected capitalization multiples based on a
comparative financial analysis of the Company and the peer group of companies.
Four peer groups of companies were selected. First, companies that manufacture
steel pipes and tubes were reviewed. Four companies were determined to be the
most representative for comparative purposes: Lone Star Technologies, Maverick
Tube Corporation, Synalloy Corporation and Webco Industries Inc. Second,
companies that manufacture electrical products for industrial use were
analyzed, because they have a similar customer base to the Company. Three
companies were chosen for comparative purposes: Aztec Manufacturing, Lamson
and Sessions Co. and Woodhead Industries. Next, the two interested purchasers
of Ocal were included, namely, Robroy and T&B. And finally, manufacturing
firms which had experienced little or no growth in the last three to five
years were
 
                                      20
<PAGE>
 
considered, because the Company's revenues and margins have generally been
flat or declining recently. Houlihan Lokey identified five publicly traded
manufacturers that fell into this low growth category: Armstrong World
Industries, Defiance Corporation, Farrel Corporation, Minnesota Mining and
Manufacturing Corporation and National Standard Company.
 
  Houlihan Lokey then compared the operational results of the Company to the
operational results of the comparable public companies. For each of the
comparable public companies, Houlihan Lokey analyzed, among other things:
market value of equity; interest-bearing debt; revenues; cash flow; earnings;
earnings before interest, taxes depreciation and amortization ("EBITDA"); and
earnings before interest and taxes ("EBIT").
 
  Houlihan Lokey then made a determination of the relative risks associated
with the business of the Company versus the businesses of the comparable
public companies, and made a determination as to the appropriate multiples to
apply to the operating results of the Company. Such comparative analyses
formed the basis for Houlihan Lokey's selection of multiples for the Company
as discussed below.
 
  With respect to profitability, as measured by EBIT and EBITDA, the Company
is generally less profitable than the comparable companies. The Company also
has had lower growth in revenues and EBITDA than the comparable companies
taken as a group. Additionally, because of pricing pressure, increasing costs,
and the potential for substitute products, the Company's sales and margins are
expected to remain flat or decline in the future. The Company is also smaller
(based on market capitalization) than all of the comparable companies.
Further, the Company has not historically paid any dividends. Therefore,
Houlihan Lokey determined that the selected multiples to apply to the
operating results of the Company should be lower than the median multiples of
the comparable companies.
 
  Multiples of the latest twelve months results ("LTM") and of the forecasted
next fiscal year results ("NFY") were used. Total invested capital ("TIC")
multiples as well as price multiples were used. Total invested capital is
defined as the book value of a company's debt and preferred equity (so long as
book value is not materially different from market value) plus the market
value of the company's equity. Price multiples are based on the total stock
market value of a company's equity. The comparable companies had TIC to LTM
revenue multiples with a mean of .6 and median of .5. Houlihan Lokey
determined a TIC to LTM revenue multiple of .4 to .5 to be reasonable for the
Company. The comparable companies had TIC to LTM EBITDA multiples with a mean
of 5.2 and median of 5.3 and TIC to NFY EBITDA multiples with a mean of 5.2
and median of 4.7. Houlihan Lokey determined a TIC to LTM EBITDA multiple with
a range of 3.5 to 4.0 and a TIC to NFY EBITDA multiple with a range of 3.5 to
4.0 to be reasonable for the Company. The comparable companies had TIC to LTM
EBIT multiples with a mean of 8.3 and median of 8.7 and TIC to NFY EBIT
multiples with a mean of 7.4 and median of 6.4. Houlihan Lokey determined a
TIC to LTM EBIT multiple with a range of 5.0 to 6.0 and a TIC to NFY EBIT
multiple with a range of 4.5 to 5.0 to be reasonable for the Company. The
comparable companies had price to LTM cash flow multiples with a mean of 5.4
and median of 5.5 and price to NFY cash flow multiples with a mean of 6.0 and
median of 5.5. Houlihan Lokey determined a price to LTM cash flow multiple
with a range of 4.5 to 5.0 and a price to NFY cash flow multiple with a range
of 4.5 to 5.0 to be reasonable for the Company. The comparable companies had
price to LTM earnings multiples with a mean of 11.2 and median of 11.5 and
price to NFY earnings multiples with a mean of 10.9 and median of 8.9.
Houlihan Lokey determined a price to LTM earnings multiple with a range of 7.0
to 8.0 and a price to NFY earnings multiple with a range of 6.0 to 7.0 to be
reasonable for the Company.
 
  To arrive at estimates of the Company's value, the selected multiples were
multiplied by the appropriate income and earnings streams. The Company's debt
was subtracted from the results of the TIC/revenues, TIC/EBITDA and TIC/EBIT
indications to arrive at an estimate of its equity value. The comparable
market multiple approach yielded marketable minority values (i.e., the value
of the entire Company without giving effect to any premium attributable to any
control element) with a median of approximately $8.3 to $9.7 million
(approximately $1.48 to $1.72 per share).
 
  The second approach that was used was the DISCOUNTED CASH FLOW APPROACH. An
abbreviated discounted cash flow analysis called the Gordon Growth model was
used to estimate of the value of the Company. The
 
                                      21
<PAGE>
 
Gordon Growth model is a perpetuity model which uses free cash flow as its
basis. This "normalized" cash flow figure incorporates expectations of the
level of cash investment (i.e., net capital expenditures and working capital)
required to maintain the Company in the future, as well as the return on
investment that the Company can be expected to sustain. Houlihan Lokey
analyzed and adjusted the forecasted financial information provided by Company
management for 1999 to determine the level of normalized cash flows. The
normalized cash flow figure was then capitalized as a perpetuity by a risk
adjusted discount rate, adjusted for some level of growth which can be
expected into perpetuity. The discount rate was determined based upon the
discount rates for the comparable companies and the risk associated with
achieving the forecast. The following is a representation of the perpetuity
method formula:
 
- --------------------------------------------------------------------------------
<TABLE>
<CAPTION>
                        T = CF\\n\\ / (WACC--G)
                        -----------------------
           <S>       <C> <C>
           Where T    = Terminal value
           CF\\n\\    = Normalized cash flow
              WACC    = Weighted-average cost of capital
              G       = Growth rate in perpetuity
</TABLE>
- ------------------------------------------------------------------------------- 
 
  After Houlihan Lokey's analysis of the Company and the comparable companies,
discount rates of 13 to 15 percent for the weighted average cost of capital
("WACC") and perpetual growth rates of 2 to 4 percent were considered
reasonable for the Company. The Company's debt was then subtracted from the
results of the Gordon Growth model to arrive at an estimate of its equity
value. The discounted cash flow approach yielded a marketable minority value
of approximately $8.2 million.
 
  Houlihan Lokey considered the value results from the discounted cash flow
and comparable market multiple approaches and concluded that a marketable
minority equity value of $8.3 to $9.6 million was reasonable for the Company.
A control premium of 30% was then added to the marketable minority value to
reach a control value of equity of $10.79 to $12.48 million. The control
premium was based upon the control premiums paid in all industries for the
period July 1, 1997 to June 30, 1998 and for the quarter ended June 30, 1998
as reported in Houlihan Lokey's CONTROL PREMIUM STUDY. During the twelve
months ended June 30, 1998, the control premiums had a mean of 36.1% and a
median of 30.9%. During the quarter ended June 30, 1998, the control premiums
had a mean of 35.1% and a median of 30.0%. Houlihan Lokey considered a control
premium of 30% to be reasonable for the Company, especially in light of the
excess cash adjustment that was made to the equity value, as described below.
 
  Houlihan Lokey analyzed the Company's working capital and, after discussions
with Company management, determined that the Company had approximately $3 to
$4 million of excess cash beyond what would be required for normal operations
of the company. This excess cash was then added to the value of the equity of
$10.79 to $12.48 million to reach a total control value of equity of $13.79 to
$16.48 million (approximately $2.43 to $2.89 per share).
 
  The third methodology involved an analysis of the Company's CURRENT MARKET
CAPITALIZATION. Although the Company's stock is not currently followed by any
Wall Street analysts, it does have institutional ownership of approximately
15% of its stock. Additionally, approximately .7% of its public float trades
on an average daily basis compared to an average of .33% for the comparable
companies. Therefore, Houlihan Lokey has concluded that the Company's stock
price is reflective of the Company's value. As of October 6, 1998, the
Company's stock was trading at $1.75 per share. With approximately 5.7 million
shares outstanding, the Company's market capitalization as of October 6, 1998
was approximately $9.98 million. Additionally, as discussed above, Houlihan
Lokey analyzed the Company's excess cash position, and determined that the
Company had $3 to $4 million of excess cash. Minority positions, such as is
represented by the Company's public stock, cannot control or liquidate non-
operating assets such as excess cash, and the Company has not paid dividends
in the past. Therefore the market price of such stock would significantly
discount the full value of the excess cash. In reconciling the value derived
from the comparable market multiple and discounted cash flow approaches
described above to the Company's public stock price, Houlihan Lokey found that
the market was in effect discounting the excess cash by approximately 50% due
to its minority position. Houlihan Lokey believes that this is not an
unreasonable
 
                                      22
<PAGE>
 
discount. On this basis the Company's current market capitalization correlates
with the results of the other two approaches.
 
  In each of the aforementioned analyses, the estimate of the value of the
Company was not greater than the Merger Consideration offered, leading
Houlihan Lokey to conclude that the consideration to be received by the
stockholders of the Company in connection with the Merger is fair to them from
a financial point of view.
 
  The aforementioned analyses required studies of the overall market, economic
and industry conditions under which the Company operates, and the Company's
operating results. Research into, and consideration of, these conditions were
incorporated into the analyses.
 
  The Fairness Opinion is based on the business, economic, market and other
conditions as they existed as of October 6, 1998. In rendering the Fairness
Opinion, Houlihan Lokey relied upon and assumed, without independent
verification, the accuracy, completeness and fairness of all of the financial
information and other information reviewed by Houlihan Lokey for purposes of
the Fairness Opinion, and that the financial results and projections provided
to Houlihan Lokey by the Company have been reasonably prepared and reflect the
best current available estimates of the financial results, condition, and
prospects of the Company. Houlihan Lokey did not independently verify the
accuracy or completeness of the information supplied to it with respect to the
Company and does not assume responsibility for it. Except as set forth above,
Houlihan Lokey did not make any physical inspection or independent appraisal
of the specific properties, assets or liabilities of the Company.
 
  The preparation of a fairness opinion is a complex analytical process
involving various determinations as to the most appropriate and relevant
methods of financial analysis and application of those methods to the
particular circumstances and is therefore not readily susceptible to summary
description. In arriving at the Fairness Opinion, Houlihan Lokey did not
attribute any particular weight to any analysis or factor considered by it,
but rather made qualitative judgments as to the significance and relevance of
each analysis and factor. Accordingly, Houlihan Lokey believes its analyses
and the summary set forth herein must be considered as a whole and that
selecting portions of its analyses, without considering all analyses, or
portions of this summary, without considering all factors and analyses, could
create an incomplete view of the processes underlying the analyses set forth
in the Fairness Opinion. In its analyses, Houlihan Lokey made numerous
assumptions with respect to the Company, industry performance, general
business, economic, market and financial conditions and other matters, many of
which are beyond the control of the Company. The estimates contained in such
analyses are not necessarily indicative of actual values or predictive of
future results or values, which may be more or less favorable than suggested
by such analyses. Additionally, analyses relating to the value of businesses
or securities do not purport to be appraisals or to reflect the prices at
which businesses or securities actually may be sold. Accordingly, such
analyses and estimates are inherently subject to substantial uncertainty.
 
CERTAIN FINANCIAL PROJECTIONS OF THE COMPANY
 
  The Company does not as a matter of course make public forecasts or
projections as to its future financial performance. Since, however,
projections were prepared for and provided to Houlikan Lokey in connection
with its services as financial advisor to the Company (see "The Merger --
Opinion of the Company's Financial Advisor"), a summary of such projections is
included herein. The projections have been included in this Proxy Statement
for the limited purpose of giving the Company's Stockholders access to
financial projections reviewed by Houlihan Lokey for purposes of the Fairness
Opinion.
 
  THE PROJECTIONS SET FORTH BELOW WERE NOT PREPARED WITH A VIEW TO PUBLIC
DISCLOSURE OR IN COMPLIANCE WITH PUBLISHED GUIDELINES OF THE SECURITIES AND
EXCHANGE COMMISSION REGARDING PROJECTIONS OR THE GUIDELINES ESTABLISHED BY THE
AMERICAN INSTITUTE OF CERTIFIED PUBLIC ACCOUNTANTS REGARDING PROJECTIONS.
 
  The projections, while presented with numerical specificity, are forward-
looking statements that are based on myriad estimates and assumptions,
including, but not limited to, those listed below, which involve judgments
with respect to, among other things, industry performance, future economic and
competitive conditions, inflation
 
                                      23
<PAGE>
 
rates and future business conditions. While the Company believes that these
estimates and assumptions are reasonable, these estimates and assumptions may
not be realized and are inherently subject to significant business, economic
and competitive uncertainties, all of which are difficult to predict and many
of which are beyond the control of the Company. Therefore, there can be no
assurance that the projections set forth below will prove to be reliable
estimates of probable future performance. It is quite likely that actual
results will vary materially from these estimates. In light of the
uncertainties inherent in projections of any kind, the inclusion of
projections herein should not be regarded as a representation by any party
that the estimated results will be realized or that the Company considers them
to be a reliable prediction of future events, and the projections should not
be relied upon as such. The projections were not prepared in accordance with
generally accepted accounting principles and were not audited or reviewed by
any independent accounting firm, nor did any independent accounting firm
perform any other services with respect thereto and none of the Company, or
T&B, or their respective affiliates or representatives, or any other person,
assumes any responsibility for the validity, accuracy, reasonableness or
completeness of such projections. The Company does not intend to update or
otherwise revise the projections to reflect circumstances existing after the
date when made or to reflect the occurrence of future events even in the event
that any or all of the estimates and assumptions underlying the projections
are shown to be in error.
 
  The Company prepared and furnished to Houlihan Lokey projections for the
years ending December 31, 1998 and December 31, 1999.

  Subject to the qualifications and limitations stated above, the information
presented herein was based, in part, on the following estimates and
assumptions.
 
  1. It was assumed that in 1999 there would be a 3% increase in revenues from
projected 1998 revenues.
 
  2. It was assumed that in 1999 the Company would be able to achieve savings
of approximately $450,000 in manufacturing costs due to the planned deployment
of new manufacturing equipment containing new technological processes. These
new processes include a newly automated urethane paint process which would
allow the Company to produce finished goods more efficiently, resulting in
savings in pipe costs, reduced need to recover pipe from scrap materials,
reduced need for fittings and reduced labor costs. The new processes also
include a new saw soon to be implemented in the Company's Alabama factory.
 
  3. It was assumed that in 1999 the Company would experience an increase in
selling, general and administrative expenses of $160,000 relating to increased
sales commissions and cost of living salary increases.
 
ACCOUNTING TREATMENT
 
  The Merger will be treated as a "purchase" for accounting purposes.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  Treatment of Outstanding Options. On October 6, 1998, the Board of
Directors, in accordance with the recommendation of the Company's Stock Option
Committee, accelerated the vesting of all issued and outstanding options
granted under the Option Plan. Such options shall be converted upon the
Effective Time into the right to receive from T&B cash equal to (x) the number
of shares of Common Stock receivable upon exercise of such option multiplied
by (y) the excess of the Per Share Merger Consideration over the per share
exercise price of the Common Stock underlying the option. Each director and
executive officer of the Company (other than Mr. Bender) holds options under
the Option Plan. There are outstanding options to purchase 155,500 shares of
Common Stock under the Option Plan, each at an exercise price of $2.375.
 
                                      24
<PAGE>
 
  Independent Consulting Agreement. In connection with the consummation of the
Merger, Mr. Bender will enter into an Independent Consulting Agreement which,
among other things, provides that Mr. Bender will be paid $100,000 to act as a
consultant for T&B following the Effective Time for a period of one year
(unless extended by written agreement by T&B and Mr. Bender).
 
  Guaranties. Under the Merger Agreement, T&B has agreed to guarantee the
repayment of certain loans made to the Company by Mr. Bender and Carlos V.
Espinosa, a director and Vice President of the Company. T&B would only be
required to make payments under the guarantees if the Company did not make
payments of principal or interest on such loans as scheduled.
 
ILAN BENDER'S ESCROW AND NON-COMPETITION COMMITMENT
 
  In connection with the consummation of the Merger, Mr. Bender will enter
into a Securityholders Agreement with T&B whereby Mr. Bender will place in
escrow $450,000 of his personal proceeds from the Merger. The amounts held in
the escrow will be used to indemnify T&B against losses arising from certain
post-closing environmental remediation costs at the Company's Mobile
manufacturing facility.
 
  The Securityholders Agreement also contains confidentiality and non-
competition provisions. According to its terms, Mr. Bender agrees that for a
period of five years following the date of the closing he will, among other
things, not (i) disclose or use certain confidential information concerning
the Company without the prior written consent of T&B or (ii) engage in the
business of manufacturing, marketing or selling the products that are
manufactured, marketed or distributed by the Company as of the Effective Date.
 
EXCHANGE PROCEDURES
 
  At or prior to the Effective Time, T&B will designate a bank or trust
company (with the Company's prior written approval) to serve as the Exchange
Agent for the shares of Common Stock. At the Effective Time, T&B will deposit,
or cause to be deposited, with the Exchange Agent for the benefit of the
holders of Certificates, cash in an amount that equals the aggregate Merger
Consideration.
 
  Promptly after the Effective Time, the Surviving Corporation will instruct
the Exchange Agent to mail to each record holder of outstanding Certificates
as of the Effective Time a form of letter of transmittal and instructions for
use in effecting the surrender of the Certificates for payment of the Merger
Consideration. Delivery shall be effected, and risk of loss and title to the
Certificate shall pass, only upon proper delivery of the Certificates to the
Exchange Agent.
 
  Upon the surrender to the Exchange Agent of a duly executed letter of
transmittal and one or more Certificates, the holder of the Certificate(s)
shall be entitled to receive only the Merger Consideration and the
Certificate(s) shall be cancelled. If payment (or any portion thereof) is to
be made to a person other than the person in whose name the Certificate
surrendered is registered, the surrendered Certificate must be properly
endorsed in accordance with the instructions on the letter of transmittal and
the person surrendering the Certificate(s) must pay to the Exchange Agent any
transfer or other taxes required by reason of the payment to a person other
than the registered holder of such surrendered Certificate(s) or establish to
the satisfaction of the Exchange Agent that such tax has been paid or is not
applicable. No interest will be paid or accrued on the cash payable upon the
surrender of Certificates.
 
SPECIFIC RIGHTS OF DISSENTING STOCKHOLDERS
 
  If the Merger is consummated, holders of shares of Common Stock are entitled
to appraisal rights under Section 262 of the Delaware General Corporation Law
("Section 262"), provided that they comply with the conditions established by
Section 262.
 
 
                                      25
<PAGE>
 
  Section 262 is reprinted in its entirety as Annex C to this Proxy Statement.
The following discussion is not a complete statement of the law relating to
appraisal rights and is qualified in its entirety by reference to Annex C.
This discussion and Annex C should be reviewed carefully by any Stockholder
who wishes to exercise statutory appraisal rights or who wishes to preserve
the right to do so, as failure to comply with the procedures set forth herein
or therein will result in the loss of appraisal rights.
 
  A record holder of shares of Common Stock who makes the demand described
below with respect to such shares, who continuously is the record holder of
such shares through the Effective Time, who otherwise complies with the
statutory requirements of Section 262 and who neither votes in favor of the
Merger nor consents thereto in writing will be entitled to an appraisal by the
Delaware Court of Chancery (the "Delaware Court") of the fair value of his or
her shares of Common Stock. All references in this summary of appraisal rights
to a "Stockholder" or "holders of shares of Common Stock" are to the record
holder or holders of shares of Common Stock. Except as set forth herein,
Stockholders of the Company will not be entitled to appraisal rights in
connection with the Merger.
 
  Under Section 262, where a merger is to be submitted for approval at a
meeting of stockholders, such as the Special Meeting, not less than 20 days
prior to the meeting a constituent corporation must notify each of the holders
of its stock for whom appraisal rights are available that such appraisal
rights are available and include in each such notice a copy of Section 262.
This Proxy Statement shall constitute such notice to the record holders of
Common Stock.
 
  Holders of shares of Common Stock who desire to exercise their appraisal
rights must not vote in favor of the Merger and must deliver a separate
written demand for appraisal to the Company prior to the vote by the
Stockholders of the Company on the Merger. A demand for appraisal must be
executed by or on behalf of the Stockholder of record and must reasonably
inform the Company of the identity of the Stockholder of record and that such
Stockholder intends thereby to demand appraisal of the Common Stock. A proxy
or vote against the Merger will not by itself constitute such a demand. Within
ten days after the Effective Time, the Company must provide notice of the
Effective Time to all Stockholders who have complied with Section 262 and have
not voted in favor of or consented to the Merger.
 
  A Stockholder who elects to exercise appraisal rights should mail or deliver
his or her written demand to the Company at 14538 Keswick Street, Van Nuys,
California 91405, Attention: Secretary.
 
  A person having a beneficial interest in shares of Common Stock that are
held of record in the name of another person, such as a broker, fiduciary,
depositary or other nominee, must act promptly to cause the record holder to
follow the steps summarized herein properly and in a timely manner to perfect
appraisal rights. If the shares of Common Stock are owned of record by a
person other than the beneficial owner, including a broker, fiduciary (such as
a trustee, guardian or custodian), depositary or other nominee, such demand
must be executed by or for the record owner. If the shares of Common Stock are
owned of record by more than one person, as in a joint tenancy or tenancy in
common, such demand must be executed by or for all joint owners. An authorized
agent, including an agent for two or more joint owners, may execute the demand
for appraisal for a Stockholder of record; however, the agent must identify
the record owner and expressly disclose the fact that, in exercising the
demand, such person is acting as agent for the record owner. If a Stockholder
holds shares of Common Stock through a broker who in turn holds the shares
through a central securities depository nominee such as Cede & Co., a demand
for appraisal of such shares must be made by or on behalf of the depository
nominee and must identify the depository nominee as record holder.
 
  A record holder, such as a broker, fiduciary, depositary or other nominee,
who holds shares of Common Stock as a nominee for others, may exercise
appraisal rights with respect to the shares held for all or less than all
beneficial owners of shares as to which such person is the record owner. In
such case, the written demand must set forth the number of shares covered by
such demand. Where the number of shares is not expressly stated, the demand
will be presumed to cover all shares of Common Stock outstanding in the name
of such record owner.
 
 
                                      26
<PAGE>
 
  Within 120 days after the Effective Time, either the Company or any
Stockholder who has complied with the required conditions of Section 262 may
file a petition in the Delaware Court, with a copy served on the Company in
the case of a petition filed by a Stockholder, demanding a determination of
the fair value of the shares of all dissenting Stockholders. There is no
present intent on the part of the Company to file an appraisal petition and
Stockholders seeking to exercise appraisal rights should not assume that the
Company will file such a petition or that the Company will initiate any
negotiations with respect to the fair value of such shares. Accordingly,
holders of Common Stock who desire to have their shares appraised should
initiate any petitions necessary for the perfection of their appraisal rights
within the time periods and in the manner prescribed in Section 262. Within
120 days after the Effective Time, any Stockholder who has theretofore
complied with the applicable provisions of Section 262 will be entitled, upon
written request, to receive from the Company a statement setting forth the
aggregate number of shares of Common Stock not voting in favor of the Merger
and with respect to which demands for appraisal were received by the Company
and the number of holders of such shares. Such statement must be mailed within
10 days after the written request therefor has been received by the Company or
within 10 days after expiration of the period for delivery of demands as
prescribed in Section 262, whichever is later.
 
  If a petition for an appraisal is timely filed, at the hearing on such
petition, the Delaware Court will determine which Stockholders are entitled to
appraisal rights. The Delaware Court may require the Stockholders who have
demanded an appraisal for their shares and who hold Common Stock represented
by certificates to submit their certificates of Common Stock to the Register
in Chancery for notation thereon of the pendency of the appraisal proceedings;
and if any Stockholder fails to comply with such direction, the Delaware Court
may dismiss the proceedings as to such Stockholder. Where proceedings are not
dismissed, the Delaware Court will appraise the shares of Common Stock owned
by such Stockholders, determining the fair value of such shares exclusive of
any element of value arising from the accomplishment or expectation of the
Merger, together with a fair rate of interest, if any, to be paid upon the
amount determined to be the fair value.
 
  Although the Company believes that the Merger Consideration is fair, no
representation is made as to the outcome of the appraisal of fair value as
determined by the Delaware Court and Stockholders should recognize that such
an appraisal could result in a determination of a value higher or lower than,
or the same as, the Merger Consideration. Moreover, the Company does not
anticipate offering more than the Merger Consideration to any Stockholder
exercising appraisal rights and reserves the right to assert, in any appraisal
proceeding, that, for purposes of Section 262, the "fair value" of a share of
Common Stock is less than the Merger Consideration. In determining "fair
value," the Delaware Court is required to take into account all relevant
factors. In Weinberger v. UOP, Inc., the Delaware Supreme Court discussed the
            -----------------------
factors that could be considered in determining fair value in an appraisal
proceeding, stating that "proof of value by any techniques or methods which
are generally considered acceptable in the financial community and otherwise
admissible in court" should be considered and that "[f]air price obviously
requires consideration of all relevant factors involving the value of a
company." The Delaware Supreme Court has stated that in making this
determination of fair value the court must consider market value, asset value,
dividends, earnings prospects, the nature of the enterprise and any other
facts which could be ascertained as of the date of the merger which throw any
light on future prospects of the merged corporation. Section 262 provides that
fair value is to be "exclusive of any element of value arising from the
accomplishment or expectation of the merger." In Cede & Co. v. Technicolor,
                                                 --------------------------
Inc., the Delaware Supreme Court stated that such exclusion is a "narrow
- ----
exclusion [that] does not encompass known elements of value," but which rather
applies only to the speculative elements of value arising from such
accomplishment or expectation. In Weinberger, the Delaware Supreme Court
                                  ----------
construed Section 262 to mean that "elements of future value, including the
nature of the enterprise, which are known or susceptible of proof as of the
date of the merger and not the product of speculation, may be considered." In
addition, Delaware courts have decided that the statutory appraisal remedy,
depending on the factual circumstances, may or may not be a stockholder's
exclusive remedy in connection with transactions such as the merger.
 
  Holders of shares of Common Stock considering seeking appraisal should
recognize that the fair value of their shares determined under Section 262
could be more than, the same as or less than the consideration they are
entitled to receive pursuant to the Merger Agreement if they do not seek
appraisal of their shares. The cost
 
                                      27
<PAGE>
 
of the appraisal proceeding may be determined by the Delaware Court and taxed
against the parties as the Delaware Court deems equitable in the
circumstances. However, costs do not include attorneys' and expert witness
fees. Each dissenting stockholder is responsible for his or her attorneys' and
expert witness expenses, although, upon application of a dissenting
stockholder of the Company, the Delaware Court may order that all or a portion
of the expenses incurred by any dissenting stockholder in connection with the
appraisal proceeding, including without limitation, reasonable attorneys' fees
and the fees and expenses of experts, be charged pro rata against the value of
all shares of stock entitled to appraisal.
 
  Any holder of shares of Common Stock who has duly demanded appraisal in
compliance with Section 262 will not, after the Effective Time, be entitled to
vote for any purpose any shares subject to such demand or to receive payment
of dividends or other distributions on such shares, except for dividends or
distributions payable to stockholders of record at a date prior to the
Effective Time.
 
  At any time within 60 days after the Effective Time, any Stockholder will
have the right to withdraw such demand for appraisal and to accept the terms
offered in the Merger; after this period, the Stockholder may withdraw such
demand for appraisal only with the consent of the Company. If no petition for
appraisal is filed with the Delaware Court within 120 days after the Effective
Time, Stockholders' rights to appraisal shall cease, and all holders of shares
of Common Stock will be entitled to receive the Merger Consideration offered
pursuant to the Merger Agreement. Because the Company has no obligation to
file such a petition, and the Company has no present intention to do so, any
holder of shares of Common Stock who desires such a petition to be filed is
advised to file it on a timely basis. Any Stockholder may withdraw such
Stockholder's demand for appraisal by delivering to the Company a written
withdrawal of his or her demand for appraisal and acceptance of the Merger
Consideration, except (i) that any such attempt to withdraw made more than 60
days after the Effective Time will require written approval of the Company and
(ii) that no appraisal proceeding in the Delaware Court shall be dismissed as
to any Stockholder without the approval of the Delaware Court, and such
approval may be conditioned upon such terms as the Delaware Court deems just.
 
BUSINESS OF T&B
 
  T&B designs, manufactures and markets, on a global basis, electrical and
electronic connectors and components with manufacturing facilities and
marketing activities in North America, Europe and the Far East. T&B's products
are sold worldwide through electrical, electronic and HVAC distributors, mass
merchandisers, catalogs and home centers, and directly to OEM markets. T&B
operates in three business segments--Electrical, OEMs and Communications.
Electrical construction and maintenance components are sold primarily in North
America, and manufactured and assembled at facilities located in the United
States, Puerto Rico, Canada and Mexico. Electronics components are sold in
North America, Europe and Asia, and manufactured at facilities in the United
States, Europe, Mexico, Japan and Singapore. Other products and components--
principally heaters, heating and ventilation systems, components for
transmission and distribution of electric power, transmission poles and

T&B's business worldwide. T&B was established in 1898 as a sales agency for
electrical wires and raceways and was incorporated in New Jersey in 1917 and
reincorporated in Tennessee in May 1996. In 1997, T&B's net sales and net
earnings were $2.1 billion and $155 million, respectively.
 
SOURCE AND AMOUNT OF FUNDS
 
  If the Merger is consummated, the funds required to consummate the Merger
are expected to be obtained from T&B's cash on hand and through T&B's existing
credit facilities.

                             THE MERGER AGREEMENT
 
  The following is a summary of material terms of the Merger Agreement, a copy
of which is included in this Proxy Statement as Annex A. The material terms of
the Merger Agreement are summarized below, but such summary is not a complete
description of the terms and conditions thereof and is qualified in its
entirety by reference to the Merger Agreement. Stockholders are urged to
review the Merger Agreement carefully.
 
GENERAL
 
  Pursuant to the Merger Agreement, at the Effective Time, Merger Sub will
merge with and into the Company and the separate corporate existence of Merger
Sub will thereupon cease, with the Company remaining as the Surviving
Corporation and becoming a wholly-owned subsidiary of T&B.
 
  As a result of the Merger, at the Effective Time, each share of Common Stock
issued and outstanding immediately prior to the Effective Time (other than
shares as to which dissenters' rights, if any, are perfected) will be
converted into and represent the right to receive the Per Share Merger
Consideration, which consists of $3.54 in cash subject to adjustment in
certain circumstances. See "--Merger Consideration Adjustment." In the Merger,
each share of capital stock of Merger Sub issued and outstanding immediately
prior to the Effective Time will be converted into and become one fully paid
and nonassessable share of common stock of the Surviving Corporation. Upon
consummation of the Merger, the registration of the Common Stock under the
Exchange Act will be terminated, and the Common Stock will cease to be
reported and listed on The Nasdaq National Market.
 
MERGER CONSIDERATION ADJUSTMENT
 
  The Merger Agreement contemplates the Per Share Merger Consideration to be
approximately $3.54 in cash. This figure is subject to reduction under certain
circumstances if and to the extent that the Company's consolidated
stockholders' equity at the end of the month immediately preceding the month
in which the Special Meeting is scheduled to occur is less than $15,029,000,
which was the Company's consolidated stockholders' equity on August 31, 1998.
 
  For purposes of the Merger Consideration adjustment, there shall be added to
the Company's consolidated stockholders' equity (a) the amount of the
Company's total expenditures (including, without limitation, materials, labor
and overhead) between December 31, 1997 and the date of the unaudited balance
sheet on the construction and repair of machinery and equipment used in the
Company's business that had not been previously capitalized, (b) the fair
market value of inventory held by, but not recorded on the books of, the
Company that was either produced by competitors of the Company or rejected by
the Company's customers, and (c) the total amount of the fees and expenses
incurred through the date of the unaudited balance sheet by the Company in
connection with the Merger, the Merger Agreement and the transactions
contemplated thereby but not to exceed $400,000.
 
  The Company does not believe, based on its current operating results, that
there will be any such reduction in the Merger Consideration. In addition, the
Merger Agreement provides that the Company may terminate the Merger Agreement
without consummating the Merger if the amount of any such reduction in the
Merger Consideration would exceed $1.5 million (approximately $0.26 per
share).
 
TREATMENT OF STOCK OPTIONS
 
  All options (both vested and unvested) to acquire Common Stock granted under
the Option Plan shall be converted upon the Effective Time into the right to
receive from T&B cash equal to (x) the number of shares of Common Stock
receivable upon exercise of such option multiplied by (y) the excess of the
Per Share Merger Consideration over the per share exercise price of the Common
Stock underlying the option. Every director and officer of the Company (other
than Mr. Bender) holds options under the Option Plan. There are outstanding
options to purchase 155,500 shares of Common Stock under the Option Plan, each
at an exercise price of $2.375.
 
                                      29

REPRESENTATIONS AND WARRANTIES; COVENANTS
 
  The Merger Agreement contains various customary representations and
warranties made by the Company relating to its capital structure, operations,
financial condition, properties and other matters including its authority to
enter into the Merger Agreement and to consummate the Merger. Mr. Bender also
made certain representations and warranties relating to the ownership of his
shares of Common Stock. T&B also made customary representations and
warranties. None of the representations made by the Company or T&B in the
Merger Agreement will survive the Effective Time.
 
  The Company has agreed that from the date of the Merger Agreement until the
Effective Time, the Company will conduct its operations in accordance with its
ordinary course of business and will use its commercially reasonable efforts
to maintain the value of the business as a going concern and the relationships
of the Company with customers, distributors, suppliers, vendors, employees,
agents, governmental authorities and others. The Company has agreed to pay
accounts payable when due and maintain inventory levels, all in accordance
with prudent business practice and the ordinary course of business. The
Company has agreed that, prior to the Effective Time, without the prior
written consent of T&B, the Company will not: (a) amend its Certificate of
Incorporation or By-laws; (b) enter into any transactions otherwise than on an
arms' length basis or any transaction with Mr. Bender or any other affiliate
of the Company; (c) pay any compensation other than in the ordinary course of
business or increase compensation of any officer or employee other than
increases in compensation for employees as may be made in the ordinary course
of business; (d) make any distributions or payments in respect of the
Company's equity securities or debt of the Company held by affiliates (other
than regularly scheduled payments of interest and principal on such debt); (e)
allow any material permit or license to lapse or terminate or fail to renew
any material permit in accordance with prudent business practice; (f) enter
into, amend, extend, terminate or permit any renewal notice period to lapse
with respect to property leases, any other lease or any other contractual
obligation that contains either consideration to be given or performed by the
Company of a value exceeding $50,000 (except (i) to the extent otherwise
required by the Merger Agreement and (ii) contractual obligations involving
sales of goods in the ordinary course of business); or (g) enter into any
contractual obligation to take any of the foregoing action.
 
  Each of the parties to the Merger Agreement has agreed to use its reasonable
best efforts to take, or cause to be taken, all actions necessary, proper or
advisable to consummate the Merger.
 
NO SOLICITATION OF BUSINESS COMBINATION PROPOSALS
 
  The Company has agreed that it will not, and will not permit any of its
subsidiaries, employees, representatives or other agents of the Company to,
directly or indirectly, solicit, initiate or enter into discussions or
transactions or contractual obligations with or encourage or provide any
information to any person (other than T&B) concerning any Business Combination
(as defined below). The Company will notify T&B immediately upon becoming
aware that any third party has made any proposal, offer, inquiry or contact
with respect to any such transaction. Notwithstanding the foregoing, the Board
of Directors may authorize the Company to furnish information to, enter into
discussions or negotiations with, or enter into an agreement with respect to a
Business Combination Proposal (as defined below) with, any third party in
connection with an unsolicited proposal in writing by such third party for a
Business Combination with the Company received by the Board of Directors after
the date of the Merger Agreement, if, and only to the extent that, (a) the
Board of Directors, after consultation with its independent legal and
financial advisors and taking into consideration the advice of such advisors,
determines in good faith that such unsolicited proposal may be more favorable
to the Stockholders than the transactions contemplated by the Merger
Agreement, and (b) prior to furnishing such information to, or entering into
discussions or negotiations with, such third party, the Company (i) gives T&B
as promptly as practicable prior written notice of the material terms of such
proposal in reasonable detail and of the Company's intention to furnish such
information or begin such discussions, and (ii) receives from such third party
an executed confidentiality agreement.
 
 
                                      30
<PAGE>
 
  A proposal for a Business Combination that follows the procedure and
satisfies the criteria set forth above is deemed to be a "BUSINESS COMBINATION
PROPOSAL". "BUSINESS COMBINATION" means any of the following involving the
Company: (1) any merger, consolidation, share exchange, business combination
or other similar transaction (other than the Merger); (2) any sale, lease,
exchange, transfer or other disposition (other than a pledge or mortgage) of
25% or more of the assets of the Company, in a single transaction or series of
transactions; or (3) the acquisition by a person or any "group" (as such term
is defined under Section 13(d) of the Securities and Exchange Act of 1934, as
amended, and the rules and regulations thereunder) of beneficial ownership of
33% or more of the shares of the Common Stock, whether by tender offer,
exchange offer or otherwise.
 
REGULATORY APPROVALS
 
  The Merger is subject to the requirements of the HSR Act and the rules and
regulations promulgated thereunder, which provide that certain transactions
may not be consummated until required information and materials have been
furnished to the Antitrust Division of the Department of Justice (the
"Antitrust Division") and the Federal Trade Commission (the "FTC") and certain
waiting periods have expired or been terminated. On October 15, 1998, the
Company and T&B each filed notification and report forms under the HSR Act
with the FTC and the Antitrust Division. On October 29, 1998, the Company and
T&B received notice of the early termination of the waiting period under the
HSR Act.
 
CONDITIONS TO THE MERGER
 
  The obligations of the Company, T&B and Merger Sub to effect the Merger are
subject to the satisfaction of a number of conditions, including among others:
(a) the termination or expiration of the applicable waiting period under the
HSR Act; (b) the receipt of all mutual consents from governmental authorities
required in connection with the consummation of the Merger; (c) the receipt of
consents under certain of the Company's specified contracts required in order
to permit the parties to consummate the Merger and the transactions
contemplated thereby; (d) the approval and adoption of the Merger Agreement by
the affirmative vote of the holders of a majority of the issued and
outstanding shares of Common Stock; and (e) the absence of any statute, rule
or regulation, or order by a court, arbitrator or governmental body, agency or
official, which restrains or prohibits the consummation of the Merger.
 
  In addition, each party's obligation to effect the Merger is subject to the
satisfaction of the following additional conditions: (a) the accuracy of the
representations and warranties made by the other party as of the closing (with
certain exceptions), except where the failure to be true or correct relates to
matters which could not reasonably be expected to have a material adverse
effect (within the meaning of such phrase under the Merger Agreement) on such
other party (provided, however, that in the case of representations and
warranties made by the Company, if the inaccuracy relates to a matter which
could reasonably be expected to have a material adverse effect on the
Surviving Corporation and such effect is reflected in the transaction balance
sheet used to compute the purchase price adjustment, if any, then T&B shall be
deemed to have waived this condition); (b) the performance in all material
aspects by the other party of its covenants; and (c) if the aggregate amount
of dissenting shares exceeds 20% of the total number of outstanding shares of
Common Stock at the Effective Time, Mr. Bender shall have elected to, and
shall have executed and delivered an agreement obligating him to pay or
reimburse T&B an amount equal to (i) that number of dissenting shares
(exclusive of any shares as to which appraisal rights are not perfected or are
lost, or withdrawn) which is greater than 20% of the outstanding shares
multiplied by (ii) the excess (if any) of the amount per share that holders of
dissenting shares received as a result of the appraisal proceedings or any
settlement thereof over the Per Share Merger Consideration, in a form
reasonably acceptable to T&B.
 
  If there is a material amendment to the Merger Agreement, including, without
limitation, a material change in the type of consideration to be delivered to
the Stockholders or a material change in the method used to determine the
purchase price, or a waiver of a material condition to the Company's
obligation to consummate the Merger, the Company will send to the Stockholders
a supplement to this Proxy Statement in advance of the Special Meeting.
 
                                      31

TERMINATION AND BREAKUP FEE
 
  The Merger Agreement may be terminated and the Merger abandoned prior to the
Effective Time, notwithstanding the approval by the Stockholders at the
Special Meeting, (a) by mutual written consent of the parties at any time
prior to the consummation of the Merger, (b) by T&B or Merger Sub (i) if the
Merger shall not have been consummated on or before March 31, 1999 by reason
of the failure of any condition to T&B's or Merger Sub's obligation to
consummate the Merger, or (ii) if the Company or Mr. Bender has failed to cure
within twenty (20) business days after receiving written notice any material

Merger Agreement (provided that if the Company or Mr. Bender is pursuing a
cure in good faith, such period for cure shall be extended until March 31,
1999); except, that such right to terminate the Merger Agreement under clauses
(b)(i) and (b)(ii) is not available if T&B or Merger Sub is in material breach
of any representation, warranty, covenant or agreement contained in the Merger
Agreement; or (iii) if the Board of Directors withdraws its recommendation of
the Merger Agreement or the Merger or shall have resolved to do so
("Recommendation Withdrawal"); (c) by the Company (i) if the Merger shall not
have been consummated on or before March 31, 1999 by reason of the failure of
any condition to the Company's obligation to consummate the Merger; (ii) if
T&B has failed to cure within twenty (20) business days after receiving
written notice any material breach of any representation, warranty, covenant
or agreement contained in the Merger Agreement (provided that if T&B is
pursuing a cure in good faith, such period for cure shall be extended until
March 31, 1999); except, that such right to terminate the Merger Agreement
under clauses (c)(i) and (c)(ii) is not available if the Company is in
material breach of any representation, warranty, covenant or agreement
contained in the Merger Agreement; (iii) if the Company (1) receives an
unsolicited business combination proposal from a third party, (2) determines
in good faith, after consultation with its independent legal and financial
advisors and taking into consideration the advice of such advisors, that such
business combination proposal may be more favorable to the Stockholders than
the transactions contemplated by the Merger Agreement, (3) before entering
into discussions with or furnishing information to the third party, gives T&B
as promptly as practicable prior written notice of the material terms of such
business combination proposal in reasonable detail and of the Company's
intention to furnish information or begin discussions, (4) receives from the
third party an executed confidentiality agreement, and (5) pays the Breakup
Fee of $600,000; or (iv) there would be a reduction in the aggregate Merger
Consideration (based on changes in the Company's consolidated stockholders'
equity) of more than $1,500,000; or (d) by either T&B or Merger Sub, or by Mr.
Bender or the Company, (i) if the Merger shall not have been consummated by
March 31, 1999; except that the right to terminate the Merger Agreement
pursuant to this clause (d)(i) will not be available to any party whose
failure to perform any of its obligations under the Merger Agreement is the
cause of or results in the failure of the Merger to be consummated by March
31, 1999; (ii) if, at the Special Meeting, approval of the holders of Common
Stock of the Merger Agreement and the Merger shall not have been obtained; or
(iii) if any governmental authority shall have issued a governmental order or
taken any other action permanently enjoining, restraining or otherwise
prohibiting the consummation of the Merger or any of the other transactions
contemplated by the Merger Agreement and such governmental order or other
action shall have become final and nonappealable.
 
  If T&B terminates the Merger Agreement because of a Recommendation
Withdrawal pursuant to clause (b)(iii) above or if the Company terminates the
Merger Agreement after receiving a proposal from a third party and complying
with the requirements described in clause (c)(iii) above, the Company must pay
T&B the Breakup Fee in immediately available funds equal to $600,000. The
Company must provide T&B prompt written notice of the aforementioned events.
 
  In the event of termination of the Merger Agreement, the Merger Agreement
shall terminate without any liability or obligations of any party to any other
party, except for (i) T&B's or Merger Sub's ongoing obligations to maintain
the confidentiality of confidential information of the Company, (ii) the
Company's obligation to pay the Breakup Fee under certain circumstances, and
(iii) any liability of a party for a willful breach of the Merger Agreement
prior to termination.

THE MAJORITY STOCKHOLDER
 
  Pursuant to the Merger Agreement, Mr. Bender, who beneficially holds, on
behalf of himself and Bender Realty, Ltd., a family partnership over which he
has voting control, approximately 54% of the outstanding shares of Common
Stock, has agreed to vote his shares in favor of the Merger and the Merger
Agreement. Mr. Bender's voting obligations will terminate if (i) the Board of
the Directors of the Company withdraws its recommendation of the Merger or the
Merger Agreement or (ii) the Merger Agreement is terminated for any reason.
 
  In connection with the consummation of the Merger, Mr. Bender and Bender
Realty, Ltd. will enter into a Securityholders Agreement with T&B whereby Mr.
Bender and Bender Realty, Ltd. will place in escrow $450,000 of their personal
proceeds from the Merger. The amounts held in the escrow will be used to
indemnify T&B against losses arising from certain post-closing environmental
remediation costs at the Company's Mobile manufacturing facility. See "The
Merger--Ilan Bender's Escrow and Non-Competition Commitment."
 
  In connection with the consummation of the Merger, Mr. Bender will enter
into an Independent Consulting Agreement which, among other things, provides
that Mr. Bender will be paid $100,000 to act as a consultant for T&B following
the Effective Time for a period of one year (unless extended by written
agreement by T&B and Mr. Bender). See "The Merger--Interests of Certain
Persons in the Merger."

                   CERTAIN TAX CONSEQUENCES TO STOCKHOLDERS
 
  The following discussion summarizes the material federal income tax
consequences of the Merger to Stockholders. The discussion does not purport to
consider all aspects of federal income taxation which may be relevant to a
Stockholder, and the tax treatment of a Stockholder may vary according to the
Stockholder's situation. Certain Stockholders (including insurance companies,
tax-exempt organizations, financial institutions, broker-dealers, foreign
corporations and persons who are not citizens or residents of the United
States) may be subject to special rules not discussed below. In addition, the
discussion does not consider the effect of any foreign, state or local tax
laws. The discussion assumes that Stockholders hold their Common Stock as
"capital assets" (generally property held for investment) within the meaning
of Section 1221 of the Internal Revenue Code of 1986, as amended (the "Code").
Finally, Stockholders should be aware that the conclusions set forth in the
following discussions could be affected by future legislation, case law, or
administrative interpretations, which could be applicable to Stockholders.
 
  The receipt of cash in exchange for Common Stock pursuant to the Merger will
be a taxable transaction for U.S. federal income tax purposes and may also be
a taxable transaction under applicable state, local and foreign tax laws. A
Stockholder will generally recognize gain or loss for U.S. federal income tax
purposes in an amount equal to the difference between such Stockholder's
adjusted tax basis in such Stockholder's Common Stock and the cash received by
such Stockholder. Such gain or loss will be a capital gain or loss if such
Common Stock is held as a capital asset.
 
  A gain or loss will be a long-term capital gain or loss with respect to
Common Stock held for more than 12 months at the Effective Time of the Merger.
In the case of individuals, the maximum long-term capital gains tax rate is
20% (and could be lower, depending on the taxpayer's tax bracket). Any capital
gain on Common Stock held for 12 months or less at the Effective Time will be
short term capital gain, which is taxed at rates up to 39.6%. In the case of
corporate Stockholders, capital gains and capital losses continue to be
classified as long-term if the holding period exceeds one year.
 
  In the case of individuals, capital losses are allowed only to the extent of
capital gains plus the lesser of (i) $3,000 ($1,500 in the case of a married
individual filing a separate tax return) or (ii) the excess of losses over
such gains. Generally, excess capital losses of individual taxpayers may be
carried forward indefinitely and used each year, subject to the limitation
described in the preceding sentence until the loss is exhausted. In the case
of corporate Stockholders, capital losses are allowed only to the extent of
capital gains. Generally, a corporation may carry its excess capital loss back
three years or forward five years, subject to certain provisions of the Code.
 
  The receipt of the Merger Consideration may be subject, under certain
circumstances, to "backup withholding" at a 31% rate. This withholding
generally applies only if the Stockholder (i) fails to furnish his or her
social security or other taxpayer identification number ("TIN") within a
reasonable time after the request therefor, (ii) furnishes an incorrect TIN,
(iii) is notified by the Internal Revenue Service that he or she has failed to
report properly interest or dividends, or (iv) fails, under certain
circumstances, to provide a certified statement, signed under penalty of
perjury, that the TIN provided is the correct number and that he or she is not
subject to backup withholding. Amounts paid as backup withholding (but not any
applicable penalties) are creditable against a Stockholder's federal income
tax liability.
 
  The foregoing discussion may not apply to Stockholders who acquire their
Common Stock pursuant to the exercise of employee stock options or other
compensation arrangements with the Company, who hold their Common Stock as
part of a straddle or other hedging transaction or who are otherwise subject
to special tax treatment. EACH STOCKHOLDER IS URGED TO CONSULT HIS, HER OR ITS
TAX ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES OF THE MERGER, INCLUDING THE
EFFECTS OF APPLICABLE STATE, LOCAL OR OTHER TAX LAWS.

                                   BUSINESS
 
GENERAL
 
  The Company is a leading domestic manufacturer of PVC coated rigid steel
conduit ("PVC-coated conduit"), elbows, and fittings. The Company's products
are primarily used in the new construction and maintenance of plants operating
in highly corrosive environments which require the highest level of protection
of electrical wiring systems against corrosion and physical damage, such as
sewage treatment, water treatment, electric power, oil refining, chemical and
pharmaceutical, pulp and paper, and food processing plants.
 
INDUSTRY OVERVIEW
 
  Market Demand. The demand for conduit stems from the need to comply with
building codes in the United States which require protection for electrical
wiring systems. Alternative forms of protection include PVC-coated conduit,
rigid steel conduit ("RSC"), plastic conduit, aluminum conduit, cable tray
(metal or fiberglass trays in which wire is laid, but not enclosed), pre-wired
armored cable integrating the functions of electrical wire and conduit into
one system, thinner-walled versions of metal conduit called intermediate
metallic conduit ("IMC") and electrical metallic tubing ("EMT"). Of the
various commercially available forms of protection for electrical wiring
systems, PVC-coated conduit is the most expensive. It is also the most durable
in corrosive environments due to the combination of the corrosion protection
of PVC coating and galvanizing with the physical protection of steel pipe.
Although alternative products generally have an initial product and
installation cost advantage over PVC-coated conduit, the Company's PVC-coated
conduit compares favorably on a life-cycle cost basis in corrosive
environments.
 
  Sales and Distribution in the Electrical Industry. The sales and
distribution structure in the electrical industry consists of independent
sales representatives, distributors, electrical contractors, end users and
project engineers. End users include industrial companies such as
International Paper Company, OxyChem, Weyerhaeuser Company, and Merck &
Company, Inc. When an end user is planning to build a new plant, it hires an
engineering firm to design, among other things, the infrastructure and
electrical system for the plant. The end user will then hire an electrical
contractor through a bidding process. Each bidding electrical contractor
generally requests one or more distributors to price the components needed to
construct the electrical system, and the distributors bid for the contractor's
order. In the electrical industry, substantially all sales of conduit, elbows,
fittings and related products are made by the manufacturer to the distributor,
who in turn sells the products to the contractor or end user.
 
BUSINESS STRATEGY
 
  The Company's business strategy is designed to increase penetration of its
traditional corrosive environment market while expanding into other markets
where the life-cycle cost and additional features of its products provide a
cost-effective solution to customer needs. The Company seeks to implement this
strategy based upon the following strengths:
 
  Industry Leadership. The Company believes it is a leading manufacturer of
PVC-coated conduit, elbows, and fittings. In terms of sales volume, management
believes the Company's total sales of $24.3 million for the year ended
December 31, 1997 place it among the two largest domestic manufacturers of
PVC-coated conduit in the industry.
 
  Marketing Focus. The Company focuses its marketing on engineers and end
users to educate them regarding the technological advantages and long-term
savings of PVC-coated conduit as compared to alternative conduit products, and
to illustrate the features of the Company's products which its competitors do
not provide. The Company's goal is to have PVC-coated conduit generally, and
where possible, the features of the Company's products in particular,
specified by engineers and end users in engineering designs for particular
projects.
 
  Leadership in Product Quality. The Company's products have protection
features which its competitors do not provide. The Company believes it is the
only manufacturer of conduit that hot dip galvanizes its own
 
                                      35

conduit after threading, increasing the corrosion protection and life of
electrical conduit systems. In addition, the Company double coats its fittings
with both blue urethane and PVC, providing additional protection unavailable
elsewhere in the industry.
 
  Low-Cost, Proprietary Manufacturing. Management believes the Company's
proprietary manufacturing technology used in its equipment and processes
allows it to be one of the lowest-cost producers in the industry. Much of the
machinery used in the Company's manufacturing process was designed and
constructed by company personnel with minimal capital investment, labor, and
material costs. The Company galvanizes its own pipe, and purchases
ungalvanized pipe in large volumes, which often enables the Company to
negotiate advantageous purchase prices. In addition, the Company compounds its
own PVC, primer, and urethane, which allows the Company to provide these
features at a lower cost than its competitors.
 
  Comprehensive Customer Service. The Company provides a broad range of
customer support services, including assistance from senior Company employees
with respect to installation and maintenance of conduit, free installation
training, and a toll-free installation hotline.
 
PRODUCTS
 
  The Company sells and manufactures a full line of PVC-coated conduit,
elbows, fittings, RSC, PVC-coated aluminum conduit and uncoated conduit
elbows, all of which range in diameter from 1/20 to 60, as well as
installation tools. The following is a more detailed description of the
product lines the Company offers:
 
  Rigid Steel Conduit is the heaviest wall conduit in use in the world and
provides the highest level of physical protection commercially available for
electrical systems. It can be used underground, in concrete, and wherever a
high level of physical protection of electrical wiring is required. The
Company believes it is the only manufacturer producing this conduit that hot
dip galvanizes the threads together with the rest of the pipe, a process
developed by the Company. The RSC manufactured by the Company is threaded at
both ends, is 109 in length, and overall wall thicknesses range from .1090 to
 .2800. The Company is one of the few suppliers of 60 diameter RSC and PVC-
coated conduit made from domestically produced steel pipe. Some of Ocal's
customers for this product need domestically produced 60 conduit in order to
comply with the requirements of projects funded by the federal government. All
federally-funded or federally-aided projects must comply with the Buy American
Act, which requires that more than 50% of the total cost of a given product's
components be attributable to components mined, produced, or manufactured in
the United States.
 
  PVC-Coated Rigid Steel Conduit is RSC coated with .040 inches ("40 mils") of
bonded PVC on the exterior of the pipe and 2 mils of blue urethane on the
interior. It is used in environments that are too corrosive to use RSC, but
where the physical protection offered by RSC is required or prudent.
 
  PVC-Coated Aluminum Conduit is aluminum pipe coated with 40 mils of bonded
PVC on the exterior of the pipe and 2 mils of blue urethane on the interior.
It is used in environments where lighter weight conduit is required.
 
  Conduit Elbows are short lengths of curved RSC or PVC-coated conduit, bent
to 90, 60, 45, or 30 degrees and threaded at both ends. Various radiuses are
available.
 
  PVC-Coated Fittings and Accessories include couplings (which have PVC
sleeves to seal the connection), liquidtight connectors, conduit bodies, beam
clamps, pulling elbows, nipples, and strut channel accessories. The Company's
fittings are coated with blue urethane on the inside and both blue urethane
and PVC on the outside, which provides added protection. The ability to bond
PVC to blue urethane is achieved through a proprietary process developed by
the Company. All of the accessories are PVC-coated and provide a complete
corrosion protection solution for the Company's end users.
 
  Installation Tools offered by the Company include electric benders used for
bending PVC-coated conduit of 1/20 to 20 , threaders for 1/20 to 40 conduit,
hickeys to bend 1/20 to 10 PVC-coated conduit, impact sockets, wrenches and
other tools to assist in the installation of its conduit.

MARKETING, DISTRIBUTION AND CUSTOMER SERVICE
 
  In-House Marketing. The Company established an in-house marketing group in
1993 with individuals experienced in sales and marketing in the electrical
industry. The group currently consists of three individuals. The Company
specifically focuses marketing efforts at the project engineer and end user
level, educating them as to the technological advantages and lower life-cycle
cost of the Company's PVC-coated conduit as compared to alternative conduit
products.
 
  Independent Sales Agents. In addition to education of engineers and
contractors so that Ocal products will be specified, the Company's marketing
group works hand-in-hand with independent regional sales agents. The Company
markets and sells its products to approximately 700 distributors or chains of
distributors through approximately 35 independent regional sales agents
throughout the United States and Canada. Shipments to customers outside of the
United States and Canada are done through an international sales agent
experienced in the exportation of electrical materials. Independent sales
agents are the functional equivalent of a manufacturer's internal sales force
in other industries. The agents market the Company's products to distributors
and handle the purchase orders from the distributors. Some agents warehouse
the Company's products, which can expedite delivery since inventory is stored
at various locations throughout the United States. Sales agents do not market
the Company's products exclusively, but they do not sell products which are in
direct competition with the Company's products. Sales agents receive
commissions, with higher commissions paid to those agents that warehouse the
Company's products at their facilities.
 
  The Company permits the return of products within certain time limits and
under certain conditions subject to a restocking charge. The Company warrants
all of its products from defect for six years.
 
  Customer Service. Another key aspect of the Company's marketing is the
customer support services it provides. Senior management and other Company
employees are available to answer questions from contractors, end users and
engineers regarding installation procedures, maintenance, product applications
and other technical areas. The Company offers free training on proper
installation of its products, sells a variety of installation tools designed
to assist in the installation of its products, and has established a toll-free
installation hotline.
 
CUSTOMERS
 
  The Company's four largest customers are multiple location distributors.
These customers are comprised of chains of individual distributors who make
independent purchasing decisions. In 1997, sales to one customer represented
10.2% of the Company's net sales. During 1996, sales to any individual
customer did not exceed 10% of the Company's net sales. During 1995, there
were two individual customers that represented 15.3% and 11.4%, respectively,
of the Company's net sales. Management believes that the loss of any one of
these distributors would not have a material adverse effect on the Company.
 
BACKLOG AND SEASONALITY
 
  The Company's business is characterized by short-term order and shipment
schedules rather than volume purchase contracts. After a distributor sends a
purchase order to the Company, the product is typically shipped within 10 to
15 days. Accordingly, the Company does not consider backlog at any given date
to be indicative of future sales. The short term delivery requirements and the
nature of the Company's business preclude any significant backlog. The
Company's business is not seasonal.
 
MANUFACTURING
 
  Raw Materials and Suppliers. The Company's principal raw materials are
carbon steel pipes which it obtains from a number of domestic primary steel
pipe producers, conduit fittings, plastics and chemicals for coating, and zinc
for galvanizing. Because the Company galvanizes its own pipe, it can purchase
pipe directly from a number of steel pipe manufacturers. Wherever practical,
vendor purchases are made in large volumes to maximize volume discounts and
optimize payment terms. The Company believes that the market is extremely
competitive, and that its relationship with suppliers is good.
 
                                      37
<PAGE>
 
COMPETITION
 
  The Company's principal competitors in the PVC-coated conduit business are
Robroy and Perma-Cote Industries. Robroy is a diversified business and has
greater financial resources than the Company. The Company faces substantial
competition in its RSC business from large, established companies such as
Allied Tube & Conduit Company, Wheatland Tube Company, the LTV Corporation,
and Western Tube, all of which have greater financial and managerial resources
than the Company. These competitors also produce IMC and EMT. Companies which
produce alternative conduit products include Easco Aluminum, Inc. and VAW of
America, Inc. in aluminum conduit; Certain Teed Incorporated and Carlon in
plastic conduit; T.J. Cope, B-Line Systems, Inc. and Enduro Fiberglass Systems
in cable tray; and AFC Cable Systems and Alflex Corporation in armored cable.
 
  With respect to PVC-coated conduit, RSC, IMC, and EMT, as well as
alternative conduit products, the Company competes based upon product
performance, quality, availability of product, speed of delivery, customer
support, and price. The Company believes it is competitive with respect to
each of these factors and that its principal competitive advantages are
product performance, quality, and price.
 
EMPLOYEES
 
  As of December 31, 1997, the Company employed 159 people, comprised of 142
in manufacturing, 14 in administration, and 3 in marketing and sales. All of
these were full-time employees. None of the Company's employees is represented
by labor unions and the Company believes that its relations with its employees
are good.
 
PROPERTIES
 
  The Company leases its corporate office and manufacturing plant. The Company
believes that its facilities are adequately maintained, in good operating
condition, and adequate for the Company's present needs.
 
  The Company's principal executive office is located in Van Nuys, California,
consisting of approximately 3,000 square feet of office space, which the
Company leases from a partnership in which the Company's majority stockholder
is the general partner, at an annual rental of $36,000 per year. The lease for
this property expires on December 31, 1998.
 
  The Company's 300,000 square foot manufacturing facility is located in
Mobile and contains a building of approximately 100,000 square feet on the
property. The lease contains certain rent escalation clauses and provides the
Company with an option to extend the lease through December 31, 2002.
 
LEGAL PROCEEDINGS
 
  The Company is currently the subject of proceedings before the Alabama
Department of Environmental Management ("ADEM") and the U.S. Environmental
Protection Agency ("USEPA") relating to certain environmental matters. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Environmental Contingencies."
 
  The Company is a party to various lawsuits arising in the ordinary course of
business. The Company does not believe that the outcome of any of these
lawsuits will have a material adverse effect on the Company's business or
financial condition.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
  This proxy statement contains "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995 which involve
risks and uncertainties. Such "forward-looking statements" include, among
other things, the projections found under the heading "Certain Financial
Projections of the Company." The actual results of the Company could differ
materially from those anticipated in these forward-looking statements as a
result of certain factors, including, without limitation, competitive
pressures on product pricing, potential delays in implementing planned
reductions in material and factory labor costs, competition from other
manufacturers of PVC-coated conduit and from manufacturers of alternative
conduit products, nominal growth in the Company's industry, dependence on key
personnel, control by the Company's majority stockholder, cyclicality of plant
expansion activities by the Company's end users, as well as the factors set
forth in the Company's 1997 Annual Report on Form 10-K, under the caption
"Risk Factors" in the Company's IPO Prospectus filed with the Securities and
Exchange Commission pursuant to Rule 424(b) on March 12, 1996, and in the
Company's other SEC filings.
 
OVERVIEW
 
  On March 18, 1996, the Company completed an initial public offering ("IPO")
of its stock. Prior to the IPO, the Company's operations were conducted by a
number of affiliated companies formed at various times in the past. The most
significant of these operating entities elected to be taxed as S corporations
under the provisions of the Internal Revenue Code. Pursuant to such elections,
stockholders of these companies included their proportionate share of the
taxable income of these companies in their personal tax returns and the
operating results of these companies reflected no provision for federal taxes.
Stockholders' compensation expense for 1995 includes amounts distributed to
these stockholders to facilitate the payment of their personal income taxes.
 
  Occidental Coating Company ("Occidental"), a California corporation, was
incorporated on December 15, 1965 to manufacture and sell PVC-coated conduit
and fittings. On November 30, 1987, OCAL, Incorporated, an Alabama corporation
("Ocal Alabama"), was formed in Mobile, Alabama initially as a place for the
importation and distribution of conduit manufactured in Costa Rica by an
affiliate of Occidental. In 1988, the California and Costa Rica plants were
consolidated and relocated to Mobile, Alabama, when the Company determined
that the advantages of manufacturing in Costa Rica could not be fully
realized. On August 1, 1993, the operations of Occidental and Ocal Alabama
were consolidated through the acquisition by Ocal Alabama of substantially all
of the assets and liabilities of Occidental at net book value. On August 24,
1995, the Company was incorporated in Delaware under the name Ocal, Inc.
 
  On March 18, 1996, all of the outstanding capital stock of Ocal Alabama,
Occidental, Ocal Data Company ("Ocal Data"), and Ocal Transport Co. ("Ocal
Transport") was acquired by the Company through capital contributions by the
respective stockholders of such companies in exchange for an aggregate of
3,250,000 shares of the Company's Common Stock (the "Reorganization"). As part
of this Reorganization, Ocal Alabama declared a $4,600,000 distribution to its
former stockholders, which represented estimated undistributed S corporation
retained earnings. Of this distribution, $1,600,000 was paid by the Company in
cash in March 1996 and the remainder of the distribution was in the form of
$3,000,000 of interest-bearing notes payable. Upon completion of the final tax
return for Ocal Alabama, an additional $300,000 distribution was declared and
paid in cash to the former stockholders in February 1997. In September of
1997, $1,500,000 principal amount of the notes was repaid in cash and at June
30, 1998, $1,500,000 principal amount of the notes (which is due on March 18,
1999) remained outstanding.
 
RESULTS OF OPERATIONS
 
 
 NINE MONTHS ENDED SEPTEMBER 30, 1998 COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 1997
 
  Net sales. The Company's net sales for the nine months ended September 30,
1998 were $19,155,000, which represented an increase of $821,000 (4.5%)
compared to net sales in the same period of 1997. The increase in net sales
was due to an increase in volume shipments of approximately 6%, with average
selling prices, including the effects of price concessions on opening orders,
down approximately 2% from the year-ago period.

  Gross margin. The Company's gross margin for the nine months ended September
30, 1998 was $5,270,000, which represented an increase of $144,000 (2.8%)
compared to the gross margin for the same period of 1997. The Company's gross
margin as a percentage of sales decreased to 27.5% for the first nine months
of 1998 from 28.0% in the same period of the prior year, primarily due to
competitive pricing. Material costs as a percentage of sales were up just
slightly (0.8% of sales) during the nine months ended September 30, 1998
compared to the year-ago period, due to certain non-recurring reductions in
the cost of materials used in the production process that were achieved in the
third quarter, which substantially offset earlier material price increases.
 
  Selling, general and administrative ("SG&A"). SG&A expenses for the nine
months ended September 30, 1998 were $3,581,000, which represented an increase
of $282,000 (8.5%) compared to the same period of 1997. As a percentage of net
sales, SG&A expenses were 18.7% for the nine months ended September 30, 1998
compared to 18.0% for the same period of 1997. The increase was due primarily
to higher legal and professional fees, which included third quarter 1998
expenses of approximately $78,000 related to the Merger, and second quarter
1998 expenses of approximately $50,000 related to the settlement of a lawsuit.
In addition, during the first nine months of 1997, the Company received
approximately $80,000 in insurance refunds relating to legal expenses incurred
during 1996. Furthermore, sales commissions for the nine months ended
September 30, 1998 were higher than the same period of the prior year due to
the higher level of sales.
 
  Interest expense. Interest expense for the nine months ended September 30,
1998 was $86,000, which represented a decrease of $69,000 (44.5%) compared to
the same period of 1997. The decrease was due to the repayment of $1,500,000
principal amount of notes payable due to former stockholders of Ocal Alabama
on September 18, 1997.
 
  Interest income. Interest income for the nine months ended September 30,
1998 was $154,000, which represented a decrease of $38,000 (19.8%) compared to
the same period of 1997. The decrease was due to lower average investment
balances, resulting from the repayment of $1,500,000 principal amount of notes
payable due to former stockholders of Ocal Alabama on September 18, 1997.
 
  Income tax expense. The Company's effective income tax rate for the nine
months ended September 30, 1998 was 35.4%, compared to 37.0% in the same
period of the prior year. The decrease was due to a lower effective state
income tax rate in 1998.
 
  Net income. Net income for the nine months ended September 30, 1998 was
$1,135,000, which represented a decrease of $40,000 (3.4%) compared to the
same period of the prior year. The decrease was due primarily to increased
selling, general and administrative expenses, partially offset by an increase
in gross margin and reductions in interest and income tax expenses.
 
 YEAR ENDED DECEMBER 31, 1997 COMPARED TO YEAR ENDED DECEMBER 31, 1996
 
  Net Sales. The Company's net sales for 1997 were $24,279,000, which
represented a decrease of $721,000 (2.9%) compared to net sales of the prior
year. The decrease in net sales was due primarily to a general slowdown in the
Company's industry, which has caused an increase in the competitive nature of
the pricing. Average selling prices of Company products decreased by
approximately 3% from 1996 to 1997. Unit shipment volumes were approximately
the same in 1997 as in 1996, with decreases of approximately 5% in pipe
volumes being offset by equivalent increases in the volumes of fittings. Sales
volume was also impacted by major end user and project activity. Net sales to
a major end user decreased from approximately $1,100,000 in 1996 to $400,000
in 1997, a decrease of $700,000. While the end user continued to do business
with the Company, it had fewer plant expansions in 1997 than in 1996.
 
  Gross Margin. The Company's gross margin for 1997 was $6,651,000, which
represented a decrease of $1,208,000 (15.4%) compared to gross margin of the
prior year. The Company's gross margin as a percentage of sales decreased to
27.4% in 1997 from 31.4% in 1996 due to a combination of a 3% decrease in
average selling prices due to competition, and increased factory labor costs.
At the beginning of the second quarter of 1997, the Company implemented wage
increases of approximately 20% for factory personnel in order to remain
 
                                      41
<PAGE>
 
competitive with wages paid by other local employers and to help reduce
employee turnover. As part of the Company's strategy to maintain and increase
its market share, the Company reduced prices in competitive situations.
 
  Selling, General and Administrative. SG&A expenses for 1997 were $3,988,000,
which represented a decrease of $39,000 (1.0%) compared to SG&A expenses of
the prior year. As a percentage of net sales, SG&A expenses were 16.4% in 1997
compared to 16.1% in 1996. The net decrease in expenses from 1997 to 1996 was
due to a reduction in legal expenses, partially offset by higher sales and
administrative salaries and expenses associated with the Company's first
annual report. During 1997, the Company received a one-time insurance refund
of approximately $80,000 relating to legal expenses incurred in 1996. Without
this refund, SG&A expenses would have been 16.8% of sales in 1997.
 
  Stockholders' Compensation. Stockholders' compensation expenses for 1997
were $347,000, which represented an increase of $34,000 (10.9%) compared to
the prior year. During the second quarter of 1997, the Company's Compensation
Committee approved salary increases to these former stockholders of Ocal
Alabama.
 
  Interest Expense. Interest expense for 1997 was $184,000, which represented
a decrease of $74,000 (28.7%) compared to the prior year. During 1996, the
Company had outstanding bank debt until its IPO. During 1997, the Company had
no outstanding bank debt and also paid off the current portion ($1,500,000) of
notes payable to former stockholders of Ocal Alabama on September 18, 1997.
 
  Interest Income. Interest income for 1997 was $243,000, which represented a
decrease of $32,000 (11.7%) compared to the prior year. During the fourth
quarter of 1996, the Company decided to invest excess cash in federally tax-
free instruments, which had a lower pre-tax yield than taxable investments
which were made during the second and third quarters of 1996.
 
  Income Tax Expense. Income tax expense for 1997 was $867,000, which
represented a decrease of $313,000 (26.5%) compared to the prior year,
primarily due to reduced income before income taxes. The Company's effective
income tax rate increased to 36.5% for 1997 compared to 33.4% for 1996. In the
first quarter of 1996, prior to the Company's Reorganization and IPO, Ocal
Alabama and Ocal Data were taxed as S corporations under the provisions of the
Internal Revenue Code, and accordingly, no provision was made for federal
income taxes for these operations. Subsequent to that date, the Company and
all of its subsidiaries became C corporations subject to state and federal
income taxes at statutory rates.
 
  Net Income. Net income for 1997 of $1,508,000 decreased by $848,000 (36.0%)
compared to net income for the prior year. The decrease was due primarily to
reduced gross margin, partially offset by lower income taxes.
 
 YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
  Net Sales. The Company's net sales for 1996 were $25,000,000, which
represented an increase of $115,000 (0.5%) compared to sales of the prior
year. Although unit volumes in 1996 increased compared to 1995, there was an
offsetting decline in selling prices due to competitive product pricing. The
Company lost an account which represented approximately 4% of 1995 sales
during 1996, and replaced the lost sales by obtaining new customers with
aggressive product pricing.
 
  Gross Margin. The Company's gross margin for 1996 was $7,859,000, which
represented a decrease of $381,000 (4.6%) compared to gross margin of the
prior year. The Company's gross margin as a percentage of sales decreased to
31.4% in 1996 from 33.1% in 1995 due to competitive pricing pressures on the
Company's net sales, as well as increased costs of raw materials.
 
  Selling, General and Administrative. SG&A expenses for 1996 were $4,027,000,
which represented an increase of $82,000 (2.1%) compared to SG&A expenses of
the prior year. The increase was due to certain
 
                                      42
<PAGE>
 
expenses associated with being a public company, such as public relations
costs and directors and officers liability insurance, as well as increased
expenses of the in-house marketing group. Overall SG&A expenses as a
percentage of net sales increased to 16.1% in 1996 from 15.9% in the prior
year.
 
  Stockholders' Compensation. Stockholders' compensation expenses for 1996
were $313,000, which represented a decrease of $2,493,000 (88.8%) compared to
expenses of the prior year. The decrease was due to a reduction in salaries
and bonuses paid to those stockholders in 1996. As described in the Overview
section above, the 1995 expense includes amounts to facilitate the payment by
these stockholders of their personal income taxes, mainly attributable to S
corporation income on their personal tax returns.
 
  Interest Expense. Interest expense for 1996 was $258,000, a reduction of
$128,000 (33.2%) compared to the prior year. The reduction was due to the
repayment of bank debt with a portion of the cash proceeds from the Company's
IPO.
 
  Interest Income. Interest income for 1996 was $275,000, earned from excess
cash proceeds available after the Company's IPO. In 1995, all excess cash from
operations was used to pay down the Company's bank debt, and therefore, no
interest income was recognized.
 
  Income Tax Expense. Income tax expense for 1996 was $1,180,000 (an effective
rate of 33.4%) compared to $22,000 for the prior year. Prior to the Company's
Reorganization and IPO, Ocal Alabama and Ocal Data were taxed as S
corporations under the provisions of the Internal Revenue Code, and
accordingly, no provision was made for federal income taxes for these
operations. Subsequent to that date, the Company and all of its subsidiaries
became C corporations subject to state and federal income taxes at statutory
rates.
 
  Net Income. Net income for 1996 was $2,356,000, which represented an
increase of $1,275,000 (117.9%) compared to the prior year. The increase was
due primarily to reduced stockholders' compensation expense, partially offset
by an increased provision for income taxes.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  At September 30, 1998, the Company's debt totaled $1,757,000, which
consisted of $1,500,000 in notes payable to former stockholders of Ocal
Alabama and $257,000 of notes payable to the Company's major stockholder.
These notes are due on March 18, 1999.
 
  The Company has a revolving bank line of credit, which provides for maximum
borrowings of $6,500,000 (subject to certain specified percentages of the
Company's accounts receivable and inventories). Interest is payable, at the
Company's option, at either the bank's prime interest rate or LIBOR plus 2.0%.
At September 30, 1998, the Company had $22,000 outstanding under a standby
letter of credit, and no borrowings outstanding under the bank line of credit.
The amount of unused credit available under the bank line of credit, based
upon the Company's collateral at September 30, 1998, was $5,182,000.
 
  The Company believes that, in the event the Merger is not consummated, cash
provided by operating activities, existing cash and cash equivalents, and
available credit will be sufficient to fund future operating and capital cash
needs for at least the next 12 to 18 months.
 
  At September 30, 1998, working capital was $13,267,000, compared to
$14,170,000 at December 31, 1997, a decrease of $903,000 (6.4%). The decrease
resulted from the reclassification of $1,757,000 principal amount of long-term
notes payable to former stockholders of Ocal Alabama and the Company's major
stockholder, which are now due in the current period, and reductions in
inventory and prepaid expenses of $615,000, offset by an increase of $988,000
in accounts receivable, and an increase in cash (net of increases in accounts
payable and accrued liabilities) of $524,000. The Company's days sales
outstanding in receivables has increased from approximately 49 days at
December 31, 1997 to approximately 52 days at September 30, 1998.
 
                                      43
<PAGE>
 
  The Company generated net cash from operating activities of $2,350,000 for
the nine months ended September 30, 1998, compared to $1,174,000 in the same
period of 1997. The primary sources of operating cash for the nine months
ended September 30, 1998 were the Company's net income, increases in accounts
payable and accrued expenses and a reduction in inventory, partially offset by
an increase in accounts receivable. During the comparable period of 1997, the
primary sources of operating cash were the Company's net income and increases
in accounts payable and accrued expenses, offset by increases in inventory,
accounts receivable and prepaid income taxes.
 
  Net cash used in investing activities consists of capital expenditures of
$553,000 for the nine months ended September 30, 1998, compared to $447,000 in
the same period of 1997. The capital expenditures for both periods were for
upgrading and expansion of the Company's manufacturing equipment to further
automate production processes.
 
  Net cash used by financing activities was $48,000 for the nine months ended
September 30, 1998, compared to $1,861,000 in the same period of 1997. During
the first quarter of 1998, the Company repurchased 20,000 shares of treasury
stock at a cost of $48,000 under the Company's stock repurchase program. The
Company's Board of Directors suspended the stock repurchase program during the
second quarter of 1998. During the nine months ended September 30,1997, the
Company repaid $1,500,000 principal amount of notes payable to former
stockholders of Ocal Alabama which matured on September 18, 1997, paid
$300,000 of previously undistributed S corporation earnings after the
finalization of Ocal Alabama's March 18, 1996 tax return in February of 1997,
and repurchased 20,000 shares of its common stock at a cost of $61,000.
 
ENVIRONMENTAL CONTINGENCIES
 
  During preliminary environmental testing conducted on T&B's behalf in
connection with its acquisition of the Company, certain contaminants were
discovered in and about the soils, surface water and ground water at the
Company's Mobile plant. A review of Company records indicated that these
materials should not be present as a result of Company processes, and the
contaminants may possibly have migrated onto Company property from off-site
property or as a result of operations of predecessor owners or operators.
Following the discovery of these materials, the Company engaged an
environmental consulting firm to perform environmental investigations at the
Mobile plant to further determine the scope of the problem. The matter has
been reported to ADEM, and ADEM has required the Company to provide an
assessment plan for further environmental investigations. ADEM has granted the
Company an extension to December 15, 1998 for submitting the assessment plan.
ADEM will then review the plan and determine whether any corrective actions
will be required.
 
  In a meeting between the Company's environmental consulting firm and ADEM
held on September 3, 1998, ADEM indicated that there would be no requirement
to address any of the on-site soil contamination. The Company believes, based
upon the opinion of the consulting firm, that ADEM is unlikely to require
active remediation of the ground water, and that ADEM will probably require
only monitoring of any surface or ground water. However, in the event that
ADEM were to require active remediation of the ground water at the Company's
Mobile facility, the estimated cost to the Company of implementing the
remediation would be approximately $200,000 to $400,000 incurred over a two to
three year period, based on the estimates provided to the Company by its
environmental consulting firm. Any remediation costs would be funded out of
cash and cash equivalents.
 
  By letter dated October 14, 1998, USEPA issued a general notice letter to
Occidental, a subsidiary of the Company, with respect to the Casmalia Disposal
Site in Santa Barbara County, California ("Casmalia"). This letter notified
Occidental that it was considered by USEPA to be a potentially responsible
party with respect to Casmalia by virtue of the fact that it allegedly
generated hazardous waste that was disposed of at the site. The letter further
advised that Occidental was considered a "de minimis" generator, and that de
minimis generators could expect to settle their liability with respect to
Casmalia for a payment in the range of $75,000 to $750,000. USEPA anticipates
that the proposed settlement will be offered to the de minimis generators
during the fourth
 
                                      44
<PAGE>
 
quarter of 1998, after which such generators will have sixty (60) days to
review and approve the offer. The Company is currently reviewing the validity
of the claim and believes, based on conversations with USEPA, that it will be
able to settle near the lower end of the range (i.e., approximately $120,000).
Although the settlement costs could be significant in relation to the
Company's results of operations in the period in which they are incurred, they
are not expected to have a material adverse effect on the Company's liquidity
or consolidated financial position. The Company will pay any settlement costs
out of cash and cash equivalents.
 
IMPACT OF THE YEAR 2000
 
  The Company is aware of the widely publicized problems associated with
computer systems as they relate to the year 2000 (the "Year 2000 Problem").
Many existing computer hardware systems and software applications, and
embedded computer chips and software in machinery and equipment use only two
digits to identify a year in the date field, without considering the impact of
the upcoming change in the century. As a result, such systems, applications
and devices could fail or create erroneous results unless corrected so that
they can correctly process data related to the year 2000 and beyond.
 
  During the second half of 1997, the Company conducted a review of its
information technology ("IT") and non-IT systems to identify those areas that
could be affected by the Year 2000 Problem. The Company's findings in
connection with that review, and its remedial and testing efforts relating to
the Year 2000 Problem, are as follows:
 
  IT Systems. The Company's IT systems are composed of a network of personal
computers. Most of the operating system and applications software applications
used by the Company are recent versions of popular vendor supported,
commercially available products, all of which are represented by their vendors
to be Year 2000 compliant. Although the Company uses custom software to handle
financial, order entry and inventory management functions, this software was
modified by the Company's computer consultant in late 1997 to ensure that it
would be Year 2000 compliant.
 
  During 1998, the Company conducted various tests of the operability and
interoperability of all business applications as well as all operating system
software in a full simulation of the Year 2000. The Company reset the system
clock for various dates and tested the processing of date information before
and after December 31, 1999, as well as the processing of the Year 2000 as a
leap year. These tests were completed successfully.
 
  Non-IT Systems. The Company identified all of the machinery and equipment
used in its manufacturing processes that contain embedded computer chips and
software. The Company determined that none of this machinery and equipment
contained date-sensitive applications and that the Year 2000 Problem was not a
relevant concern in this area.
 
  Customers and Suppliers. The Company has not, and does not intend to, survey
its customers and suppliers as to the state of their Year 2000 readiness.
However, the Company's sales representatives are the only third parties who
interface with the Company's computer systems, and such communications are
limited to the transmission to the Company of order information in non-date
sensitive format. In addition, because the Company's customer base is highly
diversified (no customer accounts for more than 5% of the Company's sales),
and customer orders could be placed by phone or facsimile without significant
inconvenience, the Company does not believe that the failure of customers to
be Year 2000 compliant poses a significant operational risk to the Company.
Likewise, the Company generally places orders for pipes and fittings (the
Company's principal raw materials) in bulk and significantly in advance, and
such orders are customarily placed via telephone. Therefore, the Company does
not believe that the failure of its suppliers to be Year 2000 compliant poses
a significant operational risk to the Company.
 
  The Company's review and remedial and testing activities relating to the
Year 2000 Problem, all of which have been completed, were conducted by Company
personnel and by the Company's computer consultants under existing service
contracts. Therefore, the Company has not been required to make out-of-pocket
expenditures in order to address the Year 2000 Problem.
 
                                      45
<PAGE>
 
  Although the Company at present does not believe that the Year 2000 Problem
poses a significant operational risk to the Company, there can be no assurance
that, under certain "worst-case" scenarios, the Company will not be materially
and adversely affected by disruptions caused by the Year 2000 Problem. These
scenarios could include general disruptions in national or regional
transportation infrastructures, or prolonged disruptions at a large number of
customers or suppliers (whether caused by failures in their computer systems
or by external disruptions). It is impossible for the Company to predict the
likelihood of such worst-case scenarios at the present time. The Company will
continue to monitor these scenarios and, in the event the Company determines
there is a significant risk that any of these scenarios could occur, will
develop appropriate contingency plans and procedures in an attempt to minimize
the effects of such a scenario.
 
  To the extent applicable, the foregoing statements are subject to the Year
2000 Information and Readiness Disclosure Act (the "Readiness Act") and are to
be regarded as year 2000 readiness disclosure' as that term is defined in the
Readiness Act. In the case of a dispute with the Company's suppliers or
customers, the Readiness Act may reduce the Company's liability or otherwise
affect a potential claimant's legal rights regarding the use or content of any
such statements.

                        REPORT OF INDEPENDENT AUDITORS
 
To the Stockholders and Board of Directors of Ocal, Inc.
 
  We have audited the accompanying consolidated balance sheets of Ocal, Inc.
as of December 31, 1997 and 1996, and the related consolidated statements of
income, stockholders' equity, and cash flows for each of the three years in
the period ended December 31, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Ocal, Inc. as
of December 31, 1997 and 1996, and the consolidated results of its operations
and its cash flows for each of the three years in the period ended December
31, 1997, in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  (A) Basis of Presentation: Concurrent with the closing of the Company's
initial public offering of common stock on March 18, 1996 (Note 4), all of the
outstanding capital stock of OCAL, Incorporated ("Ocal Alabama"), Occidental
Coating Company ("Occidental"), Ocal Data Company ("Ocal Data"), and Ocal
Transport Co. ("Ocal Transport") was acquired by the Company through capital
contributions by their respective prior stockholders in exchange for an
aggregate of 3,250,000 shares of the Company's common stock (the
"Reorganization"). The Company's Chairman, CEO and President was the sole or
majority stockholder of each of the contributed companies and is the 53.8%
stockholder of the Company as of December 31, 1997.
 
  The accounts of Ocal Alabama, Occidental, Ocal Data and Ocal Transport are
included in the accompanying consolidated financial statements of the Company
on their historical basis. The stockholders' equity section of the
consolidated financial statements for prior periods has been retroactively
restated from that reported in the Registration Statement and Prospectus
related to the Company's initial public offering to reflect the Company's
capital structure and the Reorganization with the common stock of these
entities classified as paid-in capital.
 
  All significant intercompany accounts and transactions have been eliminated
in consolidation.
 
  (B) Description of Business: The Company manufactures PVC-coated rigid steel
conduit, elbows and fittings which are sold principally in the United States
to distributors who resell the products for ultimate use principally in new
construction or as replacement parts.
 
  (C) Use of Estimates in the Preparation of Financial Statements: The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting period.
Actual results could differ from those estimates.
 
  (D) Cash and Cash Equivalents: At December 31, 1997, cash equivalents
include highly liquid investments of approximately $4,200,000 invested
primarily in tax-exempt municipal securities and high-grade commercial paper.
These investments are stated at cost which approximates fair value. The
Company considers all highly liquid instruments purchased with a remaining
maturity of three months or less to be cash equivalents.
 
  (E) Inventories: Inventories are stated at the lower of cost (first-in,
first-out method) or market and consist of the following (amounts in
thousands):

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
  (G) Revenue Recognition: The Company recognizes revenue from product sales
to customers upon shipment. The Company warrants its products against defects
for six years and has policies permitting customers to return products under
certain circumstances. In addition, certain of the Company's distributors and
agents are entitled to rebates upon attaining specified sales levels. A
provision has been made for the estimated amount of product returns and
rebates that may occur under these programs.
 
  (H) Income Taxes: The Company accounts for income taxes under Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS
109). SFAS 109 is an asset and liability approach that requires the
recognition of deferred tax assets and liabilities for the expected future tax
consequences of events that have been recognized in the Company's financial
statements or tax returns. In estimating future tax consequences, SFAS 109
generally considers all expected future events other than enactments of
changes in the tax law or rates.
 
  Prior to the Reorganization, Ocal Alabama had elected to be taxed as an S
corporation under the provisions of the Internal Revenue Code. Under those
provisions, Ocal Alabama did not pay federal or state corporate income taxes
on its taxable income. Instead, the stockholders were liable for federal and
state income taxes on Ocal Alabama's taxable income. The State of California
adopted the provisions of the S corporation election but charged a franchise
tax at the corporate level. In connection with the Company's initial public
offering, Ocal Alabama's Subchapter S election was terminated, and
accordingly, the Company then became subject to federal and state income
taxes. For information purposes, the pro forma financial information (see Note
3) includes pro forma amounts for the income taxes that would have been
recorded as if all of the Company's income during the pro forma periods
presented were taxed at C corporation rates.
 
  (I) Fair Value of Financial Instruments: The carrying values of the
Company's financial instruments, which consist of cash and cash equivalents
and notes payable--stockholders, approximate their fair values.
 
  (J) Reclassifications: Certain previously reported amounts have been
reclassified to conform to the current period presentation.
 
  (K) New Accounting Standard: In 1997, the Financial Accounting Standards
Board issued Statement No. 128, "Earnings per Share," which replaced the
calculation of primary and fully diluted earnings per share with basic and
diluted earnings per share. Unlike primary earnings per share, basic earnings
per share excludes any dilutive effects of options, warrants and convertible
securities. Diluted earnings per share is very similar to the previously
reported fully diluted earnings per share. All earnings per share amounts
presented have been recalculated to comply with Statement 128's requirements,
which did not change amounts previously reported. The effect of adopting
Statement 128 was not material.
 
  (L) Results of Operations: The results of operations for the six months
ended June 30, 1998 are not necessarily indicative of the results of
operations that may be expected for the full year ending December 31, 1998.

</TABLE>
 
  For additional disclosures regarding the stock options and warrants, see
Note 8. All options and warrants were excluded from the computation of diluted
earnings per share because the exercise prices for both the options and
warrants were greater than the average market price of the common shares
during the relevant periods, and therefore, the effect would be antidilutive.
 
3. PRO FORMA FINANCIAL INFORMATION (UNAUDITED)
 
  The pro forma financial information is prepared on a basis consistent with
pro forma information disclosed in the Registration Statement and Prospectus
related to the Company's initial public offering. The pro forma financial
information includes adjustments (i) to reduce stockholders' compensation
expense, relating to salaries and bonuses paid to certain stockholders, by
$2,493,000 for the year ended December 31, 1995, and (ii) to provide for
related income taxes as if all of the Company's income during the pro forma
periods presented were taxed at C corporation rates based upon pro forma
income before income taxes. Reconciliations between historical and pro forma
results of operations follow (in thousands except per share amounts):

6. REVOLVING BANK LINE OF CREDIT
 
  The Company has a revolving bank line of credit with SouthTrust Bank,
National Association that expires July 31, 2000 and provides for maximum
borrowings of $6,500,000 (subject to certain specified percentages of the
Company's accounts receivable and inventories). The related credit agreement
requires the maintenance of certain financial ratios and tangible net worth
amounts and provides for various restrictions, including limitations on
capital expenditures, additional indebtedness, salaries of certain officers of
the Company, and payment of dividends by the Company. Interest on borrowings
outstanding under the bank line is based, at the Company's option, on the
London Interbank Offered Rate ("LIBOR") or the bank's prime rate (8.5% at
December 31, 1997). At December 31, 1997, the annual interest rate based on
the LIBOR pricing option was LIBOR plus 2.0%, and the annual interest rate
based on the prime rate was prime. At December 31, 1997, there were no
borrowings outstanding under the bank line of credit, and the amount of unused
credit available, based upon the Company's collateral, was $4,861,000.
 
  At September 30, 1998, the Company had $22,000 outstanding under a standby
letter of credit, and no borrowings outstanding under the bank line of credit.
The amount of unused credit available under the bank line of credit, based
upon the Company's collateral at September 30, 1998, was $5,182,000.

  As part of the Reorganization on March 18, 1996, Ocal Alabama declared a
distribution to its then stockholders in an amount of $4,600,000, which was an
estimate of all of its undistributed S corporation retained earnings as of
that date. The distribution by the Company on Ocal Alabama's behalf was paid
as follows:
 
    (i) $1,600,000 was paid in cash on March 25, 1996; and
 
    (ii) $3,000,000 in notes payable were issued to the stockholders of Ocal
  Alabama, bearing interest at the rate of 6.5% per annum. On September 18,
  1997, $1,500,000 principal amount of the notes were repaid in cash, and the
  remaining $1,500,000 principal amount of the notes are payable on March 18,
  1999.
 
  The amount of undistributed S corporation retained earnings as of March 18,
1996 was finalized as $4,900,000 after Ocal Alabama's income tax return for
the period from January 1, 1996 through March 18, 1996 was completed. The
additional $300,000 of undistributed S corporation retained earnings,
classified as a distribution payable to stockholders, was paid in cash to
former stockholders in February 1997 and reflected in current liabilities at
December 31, 1996.
 
 Other
 
  The Company's corporate office is leased (at an annual rent of $36,000) from
a partnership in which the Company's majority stockholder is the general
partner, and the lease expires on December 31, 1998.

8. CAPITAL STOCK
 
 Preferred Stock
 
  The Company's Board of Directors is authorized to issue up to 5,000,000
shares of preferred stock, in series, to fix dividend rates, conversion
rights, voting rights, terms of redemption, liquidation preferences, and to
increase or decrease the number of shares in any series. No preferred stock is
currently outstanding, and the Company has no present plans to issue any
preferred stock. Specific rights granted to future holders of preferred stock
could be used to restrict the Company's ability to merge with, or sell its
assets to, a third party. The ability of the Board of Directors to issue
preferred stock could discourage, delay or prevent a takeover of the Company,
thereby preserving control of the Company by the current stockholders.
 
 Stock Options
 
  In August 1995, the Board of Directors adopted, and the stockholders of the
Company approved, the Ocal, Inc. 1995 Stock Option Plan (the "Plan"). The Plan
provides for the award of incentive stock options to employees and the award
of non-qualified stock options to employees, independent contractors,
directors and consultants. The Company reserved 400,000 shares of Common Stock
under the Plan. Options to purchase Common Stock are generally conditioned
upon continued employment or service to the Company, expire from five to ten
years after the grant date, and become exercisable commencing with the first
anniversary date of the grant. Stock options under the Plan are granted at
prices not less than the fair market value on the date of the grant.
 
  There were no options outstanding prior to the Company's initial public
offering on March 18, 1996. The following is a summary of stock option
activity under the Plan:

  The 155,500 options outstanding at December 31, 1997 have a weighted average

  On February 17, 1998, the Stock Option Committee of the Company's Board of
Directors passed a resolution to cancel all of the outstanding options under
the Plan and replace them with new option grants, effective February 18, 1998.
The new options expire ten years after the grant date, maintain the original
vesting schedule of the options they replace, and have an exercise price of
$2.375 per share.

 Pro Forma Fair Value Disclosures
 
  The Company accounts for its stock options using the intrinsic value method
prescribed in Accounting Principles Board Opinion No. 25 (APB 25), "Accounting
for Stock Issued to Employees", and related Interpretations. Accordingly, no
compensation expense related to these plans has been recognized in the
Company's financial statements. The table below sets out the pro forma amounts
of net income and net income per share that would have resulted if the Company
accounted for its stock options under the fair value recognition provisions of
SFAS No. 123, "Accounting for Stock-Based Compensation" and excludes the
effects of the above-mentioned cancellation and replacement of options (in
thousands except per share amounts):

  For purposes of pro forma disclosures, the estimated fair value of the
options is amortized over the options' vesting periods. The fair value of each
option grant is estimated on the date of grant using the Black-Scholes option-
pricing model with the following assumptions:
 
<TABLE>
<CAPTION>
                                                        1997           1996

     <S>                                           <C>            <C>
     Expected dividend yield......................          0.00%          0.00%
     Expected stock price volatility..............          43.0%          46.4%
     Risk-free interest rate......................          5.70%          6.70%
     Expected life of options.....................        5 years        5 years
     Vesting assumption........................... 33.3% per year 33.3% per year
</TABLE>
 
  The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options. The Company's stock options have
characteristics significantly different from those of traded options such as
vesting restrictions and extremely limited transferability. In addition, the
assumptions used in option valuation models are highly subjective,
particularly the expected stock price volatility of the underlying stock.
Because changes in these subjective input assumptions can materially affect
the fair value estimate, in management's opinion, the existing models do not
provide a reliable single measure of the fair value of its stock options.
 
  Pro forma net income and earnings per share are the same as reported amounts
prior to 1996, as no stock options were granted until the initial public
offering on March 18, 1996. Because options generally vest over three years
and new option grants are generally made each year, the pro forma amounts
shown above may not be representative of the pro forma effect on reported net
income in future years.
 
 Warrants
 
  At December 31, 1997, warrants to purchase up to 220,000 shares of Common
Stock were outstanding. These warrants were issued to underwriters in
connection with the Company's initial public offering, and are exercisable for
a period of four years commencing March 18, 1997 at an exercise price of $6.50
per share.

9. INCOME TAXES
 
  Through March 18, 1996, the date of the Reorganization and the Company's
initial public offering, Ocal Alabama and Ocal Data had elected to be taxed as
S corporations under the provisions of the Internal Revenue Code. Pursuant to
such elections, stockholders of these companies included their proportionate
share of the taxable income of these companies in their personal tax returns.
Accordingly, no provision for federal income taxes was required or provided
for the operations of Ocal Alabama and Ocal Data through March 18, 1996. The
State of California adopted the provisions of the S corporation election but
charged a franchise tax at the corporate level. As of March 18, 1996, as a
result of the Reorganization, the Company and all of its subsidiaries became C
corporations subject to state and federal income taxes at statutory rates.
Such income taxes are provided on the results of operations in the
accompanying consolidated statements of income for the year ended December 31,
1997 and the period from March 18, 1996 through December 31, 1996.
 
  The components of the provision for income taxes are as follows (amounts in

9. INCOME TAXES (CONTINUED)
 
  Deferred income taxes reflect the net tax effects of temporary differences
between the reported amounts of certain assets and liabilities in the
Company's financial statements and the amounts used for income tax purposes.
Significant components of the Company's deferred tax assets and liabilities
are as follows:

10. STOCKHOLDERS' COMPENSATION
 
  Stockholders' compensation in 1995 includes amounts distributed to former
stockholders of Ocal Alabama to facilitate the payment of their personal
income taxes which include the taxable income of Ocal Alabama for those years
as a result of its election of S corporation status.
 
11. LEASE COMMITMENTS
 
  The Company leases its manufacturing facilities under an agreement expiring
on December 31, 2001. The lease for the manufacturing facilities contains
certain rent escalation clauses based upon changes in the Consumer Price Index
and provides the Company with an option to extend the lease through December
31, 2002. The Company's majority stockholder has personally guaranteed the
lease obligation for the manufacturing facilities. The Company's corporate
office is leased from a partnership in which the Company's majority
stockholder is the general partner (see Note 7), and the expiration date of
that lease is December 31, 1998. The Company also leases autos under various
agreements expiring in 2000. Future minimum lease payments under noncancelable
operating leases as of December 31, 1997 are as follows (amounts in
thousands):

  Included in rent expense are amounts paid to a partnership for rental of the
Company's corporate office in the amounts indicated in Note 7.
 
12. CONCENTRATION OF CREDIT RISK AND MAJOR CUSTOMERS
 
  Financial instruments that potentially subject the Company to concentrations
of credit risk consist primarily of cash equivalents and trade receivables.
The Company places its cash equivalents with high credit quality institutions.
 
  The primary users of the Company's products are electrical contractors and
large industrial companies that obtain such products through a group of
approximately 700 distributors and resellers who purchase the products
directly from the Company. Credit is extended to these distributors and
resellers based upon an evaluation of the customer's financial condition, and
collateral is generally not required. Management does not believe significant
credit risk exists at December 31, 1997.
 
  The Company's four largest customers are multiple location distributors.
These customers are comprised of chains of individual distributors who make
independent purchasing decisions. In 1997, sales to one customer represented
10.2% of the Company's net sales. During 1996, sales to any individual
customer did not exceed 10% of the Company's net sales. During 1995, there
were two individual customers that represented 15.3% and 11.4%, respectively,
of the Company's net sales. Management believes that the loss of any of these
distributors would not have a material adverse effect on the Company.
 
13. COMMITMENTS AND CONTINGENCIES
 
  The Company is a party to various lawsuits arising in the ordinary course of
business. The Company does not believe that the outcome of any of these
lawsuits will have a material adverse effect on the Company's business or
financial condition.

</TABLE>
 
  The pro forma financial information is prepared on a basis consistent with
pro forma information appearing in the Registration Statement and Prospectus
related to the Company's initial public offering. The pro forma financial
information includes an adjustment to provide related income taxes as if all
of the Company's income prior to the IPO had been taxed at C corporation rates
based upon income before income taxes. The above earnings per share amounts
have been recalculated to comply with Statement of Financial Accounting
Standards No. 128, "Earnings per Share," which did not change amounts
previously reported.
 
15. EVENTS SUBSEQUENT TO SEPTEMBER 30, 1998 (UNAUDITED)
 
  On October 7, 1998, the Company announced that it has entered into a
definitive acquisition agreement under which it will be acquired by Thomas &
Betts Corporation. This acquisition is subject to approval by the Company's
stockholders and to review under the Hart-Scott-Rodino Act.
 
  By letter dated October 14, 1998, the United States Environmental Protection
Agency ("USEPA") issued a general notice letter to Occidental, a subsidiary of
the Company, with respect to the Casmalia Disposal Site in Santa Barbara
County, California ("Casmalia"). This letter notified Occidental that it was
considered by USEPA to be a potentially responsible party with respect to
Casmalia by virtue of the fact that it allegedly generated hazardous waste
that was disposed of at the site. The letter further advised that Occidental
was considered a "de minimis" generator, and that de minimis generators could
expect to settle their liability with respect to Casmalia for a payment in the
range of $75,000 to $750,000. USEPA anticipates that the proposed settlement
will be offered to the de minimis generators during the fourth quarter of
1998, after which such generators will have sixty (60) days to review and
approve the offer. The Company is currently reviewing the validity of the
claim and, based on conversations with USEPA, believes that it will be able to
settle near the lower end of the range (i.e., approximately $120,000).
Although the settlement costs could be significant in relation to the
Company's results of operations in the period in which they are incurred, they
are not expected to have a material adverse effect on the Company's liquidity
or consolidated financial position.

virtue of the Merger and without any action on the part of the holders
thereof, the outstanding shares of Ocal Common Stock (other than Dissenting
Shares) shall be canceled and converted in the manner set forth below.
 
    (a) Ocal Common Stock. At the Effective Time, each outstanding share of
  Ocal Common Stock (other than Dissenting Shares) shall be converted into
  the right to receive from T&B (i) the Merger Consideration divided by (ii)
  the total number of shares of Ocal Common Stock outstanding immediately
  prior to the Effective Time ("Per Share Merger Consideration"). Each
  Certificate (a "Certificate") formerly representing any of such shares of
  Ocal Common Stock shall thereafter represent only the right to the Per
  Share Merger Consideration, multiplied by the number of shares of Ocal
  Common Stock represented by that Certificate.
 
    (b) Ocal Options. Each Ocal Option outstanding at the Effective Time
  shall be converted into the right to receive from T&B cash equal to (x) the
  number of shares of Ocal Common Stock receivable upon exercise of such
  option multiplied by (y) the excess of the Per Share Merger Consideration
  over the consideration payable upon such exercise per share of Ocal Common
  Stock to be received (such sum in the aggregate, the "Option Pay-out").
 
    (c) Treasury Stock. Each share of Ocal Common Stock that is held in the
  Ocal treasury immediately prior to the Effective Time (if any) shall be
  canceled and retired and all rights in respect thereof shall cease to
  exist, without any conversion thereof or payment of any consideration
  therefor.
 
    (d) Acquisition Subsidiary. At the Effective Time, each share of Common
  Stock, $.10 par value, of the Acquisition Subsidiary issued and outstanding
  immediately prior to the Effective Time shall be converted into one share
  of Common Stock of the Surviving Corporation.
 
    (e) Merger Consideration. The "Merger Consideration" shall mean (i)
  $20,300,000, (ii) less the Option Pay-Out, and (iii) less the Deficit
  Amount as reflected on the Transaction Balance Sheet, if any.

  Section 3.2. Exchange of Certificates for Cash.
 
  (a) Exchange Agent. At the Effective Time, T&B shall deposit, or shall cause
to be deposited, with an exchange agent selected by T&B with Ocal's prior
written approval, which shall not be unreasonably withheld (the "Exchange
Agent"), for the benefit of the holders of Ocal Common Stock, the Merger
Consideration in exchange for outstanding shares of Ocal Common Stock upon due
surrender of the Certificates (or affidavits of loss in lieu thereof) pursuant
to the provisions of this Article III (the "Exchange Fund").
 
  (b) Exchange Procedures. Promptly after the Effective Time (but in no event
more than five (5) business days thereafter), the Surviving Corporation shall
cause the Exchange Agent to mail to each holder of record of shares of Ocal
Common Stock (other than holders of Dissenting Shares) (i) a letter of
transmittal specifying that delivery shall be effected, and risk of loss and
title to the Certificates shall pass, only upon delivery of the Certificates
(or affidavits of loss in lieu thereof) to the Exchange Agent, such letter of
transmittal to be in such form and have such other provisions as T&B and Ocal
may reasonably agree, and (ii) instructions for use in effecting the surrender
of the Certificates in exchange for the Per Share Merger Consideration.
Subject to Section 3.3, upon surrender of a Certificate for cancellation to
the Exchange Agent together with such letter of transmittal, duly executed,
the holder of such Certificate shall receive in exchange therefor the Per
Share Merger Consideration. No interest will be paid or accrued on any amount
payable upon due surrender of the Certificates. In the event of a transfer of
ownership of shares of Ocal Common Stock that is not registered in the
transfer records of Ocal, a check for the Per Share Merger Consideration upon
due surrender of the Certificate may be issued and/or paid to such a
transferee of the Certificate formerly representing such shares of Ocal Common
Stock if presented to the Exchange Agent, accompanied by all documents
required to evidence and effect such transfer and to evidence that any
applicable stock transfer taxes have been paid.
 
  (c) Transfers. After the Effective Time, there shall be no transfers on the
stock transfer books of Ocal of the shares of Ocal Common Stock that were
outstanding immediately prior to the Effective Time.
 
  (d) Termination of Exchange Fund. Any portion of the Exchange Fund that
remains unclaimed by the holders of Ocal Common Stock for 180 days after the
Effective Time shall be paid to T&B. Any holders of Ocal Common Stock who have
not theretofore complied with this Article III shall thereafter look only to
T&B for payment of the Per Share Merger Consideration issuable pursuant to
Section 3.1 and Section 3.2 upon due surrender of their Certificates (or
affidavits of loss in lieu thereof), in each case, without any interest
thereon. Notwithstanding the foregoing, none of T&B, the Surviving
Corporation, the Exchange Agent or any other Person shall be liable to any
former holder of shares of Ocal Common Stock for any amount properly delivered
to a public official pursuant to applicable abandoned property, escheat or
similar laws.
 
  (e) Lost, Stolen or Destroyed Certificates. In the event any Certificate
shall have been lost, stolen or destroyed, upon the making of an affidavit of
that fact by the Person claiming such Certificate to be lost, stolen or
destroyed and, if required by T&B, the posting by such Person of a bond in
customary amount as indemnity against any claim that may be made against it
with respect to such Certificate, the Exchange Agent will issue in exchange
for such lost, stolen or destroyed Certificate the Per Share Merger
Consideration upon due surrender of and deliverable in respect of the Shares
represented by such Certificate pursuant to this Agreement.
 
  Section 3.3. Dissenting Shares. Notwithstanding anything to the contrary in
this Agreement, shares of Ocal Common Stock outstanding immediately prior to
the Effective Date and held by a stockholder who has not voted in favor of the
Merger or consented thereto in writing and who has demanded appraisal rights
for such shares of Ocal Common Stock in accordance with the provisions of
(S)262 of the DGCL ("Dissenting Shares") shall not be converted into the right
to receive any consideration that may be distributable in the Merger, unless
such stockholder fails to perfect or withdraws or otherwise loses his or her
right to appraisal. If, after the Effective Time, such holder fails to perfect
or withdraws or loses his or her right to appraisal, such shares shall be
treated as if they had been converted as of the Effective Time into a right to
receive the Per Share Merger Consideration provided herein with respect to his
or her shares of Ocal Common Stock, without interest thereon.

Ocal and its Subsidiaries is qualified or licensed to do business as a foreign
corporation in every jurisdiction where the character of the property owned,
leased or operated by it or the nature of the Business as currently conducted
by it makes such qualification or licensing necessary, except where its
failure to be so qualified or licensed and in good standing has not and will
not have a Company Material Adverse Effect.
 
  Ocal has delivered to the Buying Parties a complete and correct copy of the
Charters and by-laws of Ocal and its Subsidiaries, each as amended to date.
Ocal's Charter and by-laws so delivered are in full force and effect. Schedule

and its Subsidiaries are organized and qualified to do business.
 
  The Board of Directors of Ocal has [UNANIMOUSLY] approved this Agreement and
the Merger and other transactions contemplated hereby and has received the
opinion of its financial advisors, Houlihan, Lokey, Howard and Zukin, to the
effect that the Merger Consideration is fair to the holders of Ocal Common
Stock from a financial point of view, a copy of which opinion has been
delivered to T&B.
 
  (b) Authorization and Enforceability. Subject only to the requirement that
this Agreement be approved by the holders of the Ocal Common Stock pursuant to
the Legal Requirements of the DGCL, this Agreement and the consummation of the
transactions contemplated hereby have been duly authorized, and this Agreement
has been duly executed and delivered by Ocal and is Enforceable against Ocal.
Upon such vote and approval, this Agreement will be duly authorized, executed
and delivered by, and Enforceable against Ocal. Other than the filings and/or

obtained by Ocal from any Governmental Authority in connection with the
execution and delivery of this Agreement by Ocal and the consummation by Ocal
of the Merger and the other transactions contemplated hereby, except those
that the failure to make or obtain are not, individually or in the aggregate,
reasonably likely to have a Company Material Adverse Effect or prevent
material delay or materially impair the ability of Ocal to consummate the
transactions contemplated by this Agreement.
 
  (c) Non-Contravention. Neither the execution, delivery or performance of
this Agreement nor the consummation of any of the transactions contemplated
hereby (including, without limitation, the consummation of the Merger) does or
will constitute, result in or give rise to (i) a breach or violation of or
default under any Legal Requirement applicable to Ocal and its Subsidiaries,
(ii) a breach of or a default under any Charter or By-Law provision of Ocal
and its Subsidiaries, (iii) the acceleration of the time for performance of

15,000,000 shares of Ocal Common Stock, of which 5,681,000 shares were

any shares of capital stock or other Equity Securities of Ocal.
 
  Section 6.2. Ocal Reports
 
  (a) SEC Reports. Ocal has delivered or made available to T&B each
registration statement, report, proxy statement or information statement
prepared by it since December 31, 1997 (the "Audit Date"), including
(i) Ocal's Annual Report on Form 10-K for the year ended December 31, 1997 and
(ii) Ocal's Quarterly Reports on Form 10-Q for the periods ended March 31,

amendments thereto) filed with the Securities and Exchange Commission (the
"SEC") (collectively, including any such reports filed subsequent to the date
hereof, the "Ocal Reports"). As of their respective dates, the Ocal Reports
did not, and any Ocal Reports filed with the SEC subsequent to the date hereof
will not, contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the
statements made therein, in light of the circumstances in which they were
made, not misleading. Each of the consolidated balance sheets included in or
incorporated by reference into the Ocal Reports (including the related notes
and schedules) fairly presents, or will fairly present, the consolidated
financial position of the Ocal and its Subsidiaries as of its date and each of
the consolidated statements of income, shareholders' equity and cash flows
included in or incorporated by reference into the Ocal Reports (including any
related notes and schedules) fairly presents, or will fairly present, the
results of operations, as the case may be, of Ocal and its Subsidiaries for
the periods set forth therein (subject, in the case of unaudited statements,
to notes and normal year-end adjustments) in each case in accordance with
Generally Accepted Accounting Principles consistently applied during the
periods involved, except as may be noted therein.

  (b) Absence of Certain Changes. Except as disclosed in the Ocal Reports
filed prior to the date hereof or as set forth on Schedule 6.2(b), since the
Audit Date, Ocal has conducted its Business only in, and has not engaged in
any material transaction other than according to, the Ordinary Course of
Business and there has not been (i) as of the date hereof, any change in the
financial condition, properties, business or results of operations of Ocal and
its Subsidiaries or any development or combination of developments affecting
Ocal of which the Company has knowledge, except those changes, developments or
combinations of developments that, individually or in the aggregate, are not
reasonably likely to have a Company Material Adverse Effect; (ii) any material
damage, destruction or other casualty loss with respect to any material asset
or property owned, leased or otherwise used by Ocal or any of its
Subsidiaries, whether or not covered by insurance; (iii) any declaration,
setting aside or payment of any dividend or other distribution in respect of
the capital stock of Ocal, except for dividends or other distributions on its
capital stock publicly announced prior to the date hereof; or (iv) any change
by Ocal in accounting principles, practices or methods. Since the Audit Date,
except as provided for herein or as disclosed in the Ocal Reports filed prior
to the date hereof or on Schedule 6.2(b), there has not been any increase in
the compensation payable or that could become payable by Ocal or any of its
Subsidiaries to officers or any amendment of any of the Compensation and
Benefit Plans (as defined below) other than increases or amendments in the
Ordinary Course of Business.
 
  Section 6.3. Liabilities. Except as set forth on Schedule 6.3, after giving
effect to the Closing hereunder and the consummation of the transactions
contemplated hereby, the Company will not have any Liabilities which have had
or resulted or are reasonably likely to have or result in any Company Material
Adverse Effect, other than Liabilities (a) to the extent set forth on the
unaudited consolidated balance sheet of Ocal and its Subsidiaries as of June
30, 1998, (the "Interim Balance Sheet") and the notes thereto; or (b) incurred
in usual amounts since the date of the Interim Balance Sheet in the Ordinary
Course of Business; or (c) except as disclosed in the Ocal Reports.
 
  Section 6.4. Assets.
 
  (a) Title to Assets. The Company has good and marketable title to, or, in
the case of property held under lease or other Contractual Obligation, a valid
and Enforceable right to use under an Enforceable Lease or License, all of its
properties, rights and assets, whether real, personal or intellectual and
whether tangible or intangible collectively, (the "Assets"), including,
without limitation, all properties, rights and assets reflected in the audited
consolidated balance sheet of Ocal and its Subsidiaries as of December 31,
1997 (the "Audited Balance Sheet") or in the Interim Balance Sheet (except as
sold or otherwise disposed of since the date of the Audited Balance Sheet and
the Interim Balance Sheet, respectively) with only such exceptions as could
not reasonably be expected to have a Company Material Adverse Effect. The
Assets (including, without limitation, the Equipment, the Intangibles and the
Contracts) are sufficient to permit Ocal and its Subsidiaries to conduct the
Business as currently being conducted with only such exceptions as could not
reasonably be expected to have a Company Material Adverse Effect. Except as
set forth on Schedule 6.4(a), all of the Company's Assets are located at the
Leased Properties.
 
  (b) Equipment. All of the tangible personal property other than inventory
included in the Assets and material to the operation of the Company's Business
(the "Equipment") is in good working order, operating condition and state of
repair, ordinary wear and tear and routine downtime for maintenance excepted,
and except for failures to be in good working order, operating condition or
state of repair that could not reasonably be expected to have a Company
Material Adverse Effect. Schedule 6.4(b) lists each lease or other Contractual
Obligation (including all amendments) under which any Equipment having a cost
or aggregate capital lease obligations in excess of $25,000 is held or used by
the Company (the "Leases"). The Company has delivered to T&B true and complete
copies of each Lease and any and all other material Contractual Obligations
relating to any of the Leases, in each case as in effect on the date hereof
and (except as otherwise required by this Agreement) as it will be in effect
at the Closing, including, without limitation, all amendments. There is no
Contractual Obligation under which the Company is liable as lessor with
respect to any real property or Equipment. Schedule 6.4(b) lists the addresses
of each other location, if any, at which is located any Equipment or
inventory.

    (i) The Company has not received any written notice that the use of the
  Leased Property by the Company fails to comply with any applicable Legal
  Requirements, including, to the knowledge of the Company, applicable zoning

  option or right reserved to the lessor under the applicable Property Lease
  or any notice of default under the applicable Property Lease, with such
  exceptions in each of the foregoing clauses (A) and (B) that could not
  reasonably be expected to result in any Company Material Adverse Effect.
 
    (iii) The Company has not received any written notice and has no
  knowledge of (i) any violation of any Legal Requirement, including, without
  limitation, zoning restrictions and ordinances, health, building, life,
  safety and fire codes and ordinances and Environmental Laws, affecting the
  Leased Properties, (ii) any violation of any Permit, or (iii) any eminent
  domain, condemnation or similar proceeding pending or threatened, or any
  decree or order relating thereto, which could reasonably be expected to
  materially affect the current or proposed use of the Leased Properties, or
  any building or improvement by the Company, in each case, that could
  reasonably be expected to have a Company Material Adverse Effect.
 
    (iv) No consent is required under the Property Leases in connection with
  the transactions contemplated by this Agreement.
 
    (v) The Company has not received any written notice of, nor does the
  Company have any knowledge of, any material destruction, damage or casualty

    (vii) To the Company's knowledge, with respect to the Property Leases:

  of time or both), would impair any right of the Company to exercise and
  obtain the benefit of any options contained in the Property Leases; (b)
  there is no default or basis for acceleration, repossession or termination
  under any of the Property Leases, nor has any event occurred which (with
  the giving of notice or the passage of time or both) would constitute a
  default or result in or permit the repossession, acceleration of any
  obligation under, or termination of, any of the Property Leases; and (c)
  the Company has not received any notice of any default under any ground
  lease, prime lease, mortgage or deed of trust of any lessor, any prime
  lessor or with respect to the Leased Properties which could ultimately
  result in a repossession under or termination of any of the Property Leases
  or impair any right of the Company under any of the Property Leases.
 
    (viii) There is no tenant improvement work in progress or remaining
  incomplete under the Property Leases or any construction ongoing or
  remaining incomplete with respect to the Leased Properties with a value in
  excess of $100,000 in the aggregate.
 
    (ix) All necessary services including water, electric, telephone and gas
  utility services and storm drainage facilities are currently available to
  the Leased Properties and are adequate for the present use of the Leased
  Properties by the Company, and are provided by independent third parties.

  Section 6.5. Intellectual Property Rights. Schedule 6.5 lists and identifies
the following items included in Intangibles: all trade and product names;
patents, patent applications, trademarks, service marks, and registered
copyrights (including registrations and applications). Schedule 6.5 also
identifies each Contractual Obligation (including all amendments) under which
any material Intangible is held or used by the Company in the conduct of the
Business or otherwise (the "Licenses"). Except as disclosed on Schedule 6.5,
all material Intangibles are owned solely by the Company or licensed to it
under a non-cancelable License not requiring payment of any further royalty or
fee. There is no Contractual Obligation under which the Company is liable as
licensor with respect to any Intangibles and the Company has not granted
licenses to any third party with respect to any of the Intangibles. Except for
matters that could not reasonably be expected to have a Company Material
Adverse Effect, the manufacture, use or sale by the Company of any products in
the Business and use by the Company of the Intangibles as currently used does
not infringe and has not infringed upon, in any material respect, any rights
of any third party, and, to the knowledge of the Company, no activity of any
third party infringes upon the rights of the Company with respect to any of
the Intangibles. No Action alleging or relating to any such infringement
against the rights of the Company, or by the Company against any third parties
is currently pending or, to the knowledge of the Company, threatened.
 
  Section 6.6. Accounts. Schedule 6.6 identifies each bank account or similar
account for the deposit of cash or securities maintained by or on behalf of

authority with respect to such account).

                                     A-17
<PAGE>
 
  (v) settlement of claims, (vi) merger, consolidation or other business
  combination, or (vii) any series or group of related transactions or events
  of a type specified in subclauses (i) through (vi);
 
    (h) All contracts with any Governmental Authority and all Contractual
  Obligations with distributors, suppliers, vendors, customers, or other
  purchasers or suppliers of goods or services, including, without

  The Company has heretofore delivered to T&B a true, correct and complete
copy (or, in the case of oral contracts or arrangements, an accurate written
summary) of each of the Contractual Obligations listed on Schedule 6.7, each
as in effect on the date hereof and (except as otherwise required by this
Agreement) as it will be in effect at the Closing, including, without
limitation, all amendments (such Contractual Obligations, together with the
Property Leases, the Leases, Licenses, and Insurance Policies, but excluding
the Existing Plans, being referred to herein collectively as the "Contracts").
To the Company's knowledge, each Contract is, and after giving effect to the
Closing hereunder and the consummation of the transactions contemplated hereby
will be, Enforceable by the Company against each Person (other than the
Company) party thereto, except: (i) as otherwise required by the terms of this
Agreement, (ii) for such failures to be so enforceable as do not and will not
have a Company Material Adverse Effect and (iii) as such enforceability may be
limited by (A) bankruptcy, insolvency, reorganization or other similar laws
affecting creditors' rights generally and (B) general principles of equity
(whether considered in a proceeding at law or in equity). To the Company's
knowledge, no breach or default by the Company under any of the Contracts has
occurred and is continuing, and no event has occurred which with notice or
lapse of time would constitute such a breach or default or permit termination,
modification or acceleration by any other Person under any of the Contracts,
except in each such case as has not had and will not have a Company Material
Adverse Effect. No breach or default by any other Person under any of the
Contracts has occurred and is continuing, and no default has occurred which
with notice or lapse of time would constitute such a breach or default or
permit termination, modification or acceleration by the Company under any of
the Contracts, except in each such case as has not had and will not have a
Company Material Adverse Effect.
 
  Section 6.8. Insurance. All material properties owned or used by the Company
are covered by valid and currently effective insurance policies issued in
favor of the Company in amounts which are customary in the place in which such
properties are located for companies operating similar businesses and
operations. All insurance policies in coverage amounts required under the
Property Leases and the Leases are in force under valid and currently
effective insurance policies. In the event of any Loss or claim resulting in
any insurance recovery related to the Company or the Business, the amount of
any such recovery related to the Company or the Business will be paid to the
Company. Ocal has previously delivered to the Buying Parties a summary of all
policies or binders of insurance by which the Company (or any risk of the
Business) is insured (the "Insurance Policies"). The Company has paid all
premiums due under such policies, and the Company is not in default with
respect to its obligations under any of such policies. The Company does not
have, and has never had, any self-insurance arrangements other than insurance
deductibles.
 
  Section 6.9. Transactions with Affiliates. Except for the matters described
in the Ocal Reports or as set forth on Schedule 6.9 (the "Affiliate
Relationships"), no Affiliate of the Company is an owner, officer, director,
employee, or consultant of any, competitor, customer, distributor, supplier or
vendor of the Company, or is party to any Contractual Obligation with the
Company. There are no Intangibles which are material to the operation of the
Business, or other proprietary or confidential knowledge, that any such
Affiliate (other than the Company) owns or licenses or otherwise has the right
to use which are used in the Business.

  Section 6.13. Employee Benefit Plans.
 
  (a) Schedule 6.13 lists all Employee Plans to which the Company contributes
or is obligated to contribute, or under which the Company has or may have any
material liability (each an "Existing Plan"). For purposes of this Agreement,
the term "Employee Plan" means any single employer, multiple employer, or
multiemployer plan, program, agreement, policy or arrangement (each, a
"plan"), whether or not reduced to writing, that is: (i) a welfare benefit
plan within the meaning of Section 3(1) of ERISA (a "Welfare Plan"); (ii) a
pension benefit plan within the meaning of Section 3(2) of ERISA (a "Pension
Plan"); (iii) a stock bonus, stock purchase, stock option, restricted stock,
stock appreciation right or similar equity-based plan; or (iv) any other
deferred-compensation, retirement, welfare-benefit, bonus, incentive or
fringe-benefit plan. With respect to each Existing Plan, the Company has
provided or made available to T&B accurate, current and complete copies of
each of the following: (1) where the plan has been reduced to writing, the
plan document together with all amendments; (2) where the plan has not been
reduced to writing, a written summary of all material plan terms; (3) where
applicable, copies of any trust agreements, custodial agreements, insurance
policies, administration agreements and similar agreements, and investment
management or investment advisory agreements; (4) copies of any summary plan
descriptions, employee handbooks or similar employee communications; (5) in

and any related correspondence, including a copy of the request for such
determination; (6) in the case of any funding arrangement intended to qualify

entity that is or at any time previously was, a member of the same Controlled
Group as the Company has ever maintained or been required to contribute to any
Employee Plan subject to Title IV of ERISA.
 
  (c) Each Existing Plan maintained with respect to employees or former
employees (or their beneficiaries) of the Company that is intended to be
qualified under Section 401(a) of the Code has been determined by the IRS to
be so qualified. Each Existing Plan, including any associated trust or fund,
has been administered in all material respects in accordance with its terms
and with all applicable Legal Requirements, and nothing has occurred with
respect to any Existing Plan that has subjected or could subject the Company
to a liability in any material amount under Section 502 of ERISA or Chapter 43
of Subtitle D or Section 6652 of the Code, or that has subjected or could
subject any participant in or beneficiary of an Existing Plan to a tax in any
material amount under Section 4974 of the Code, other than liabilities which
have been paid in full.

transmission of employee contributions) on account of each Existing Plan for

lawsuits, claims or other controversies relating to an Existing Plan, other
than claims for information or benefits in the normal course.
 
  (f) The Company does not maintain any Employee Plan which provides severance
benefits; and except as set forth on Schedule 6.13, the Company does not have
an obligation to provide severance to any employees in the event of
termination of employment. Other than as required under Section 601 et seq. of
ERISA, no Existing Plan that is a Welfare Plan maintained with respect to
employees (or their beneficiaries) of the Company provides benefits or
coverage following retirement or other termination of employment. Each welfare
benefit trust or fund that constitutes or is associated with an Existing Plan
and that is intended to be exempt from federal income tax
 
                                     A-21

under Section 501(c)(9) of the Code is so exempt. No event has occurred that
could result in a loss of any deduction to the Company under Section 162(m) of
the Code.
 
  (g) No provision of any Existing Plan would result in any limitation on the
ability of the Company, or any Buying Party to terminate the plan that is not
otherwise set forth on Schedule 6.13.

on the part of the Company (or, after the Closing, either Buying Party) either
at the present or at any future time (excepting Liability or Losses predicated
upon unforeseen changes in the law) (including, without limitation, any
obligation to conduct any remedial or monitoring work) under any Environmental
Laws or otherwise resulting from or relating to the handling, storage, use,
transportation or disposal of any Hazardous Substance by or on behalf of the

corporation in every jurisdiction where the character of the property owned,
leased or operated by it or the nature of the business as currently conducted

  (b) Capitalization of Acquisition Subsidiary. The authorized capital stock
of Acquisition Subsidiary consists of 900 shares of Common Stock, $.10 par
value, all of which are validly issued and outstanding, and 100 shares of

contemplated hereby by either Buying Party, except for items which shall have
been obtained or made and shall be in full force and effect at the Closing.
 
  Section 7.3. Non-Contravention. Neither the execution, delivery or
performance of this Agreement nor the consummation of the transactions
contemplated hereby (including, without limitation, the consummation of the
Merger) does or will constitute, result in or give rise to (i) a breach or
violation of or default under any Legal Requirement applicable to T&B and its
Subsidiaries, (ii) a breach of or a default under any Charter or By-Laws
provision of either Buying Party, (iii) the acceleration of the time for

Adverse Effect on T&B and its Subsidiaries as a whole.
 
  Section 7.4. Litigation. There is no Action pending or (to the knowledge of
the Buying Parties) threatened, nor (to the knowledge of the Buying Parties)
any basis therefor, which seeks rescission of, seeks to enjoin the

transactions contemplated hereby. No Governmental Order has been issued which
has had or will have a Material Adverse Effect on the ability of either Buying
Party to perform its obligations under this Agreement.

                                 ARTICLE VIII
 
                       CERTAIN AGREEMENTS OF THE PARTIES
 
  Section 8.1. No Solicitation of Other Offers. The Major Securityholders will
not, and will use their reasonable best efforts to cause Ocal and all of their
and its Affiliates and all of their and its respective employees,
representatives and agents not to, and Ocal will not, directly or indirectly,
solicit or initiate or enter into discussions or transactions or Contractual
Obligations with or encourage or provide any information to any Person (other
than the Buying Parties, and their designees) concerning any Business
Combination. The Major Securityholders will, and will use their reasonable
best efforts to cause Ocal to, and Ocal will notify the Buying
 
                                     A-25
<PAGE>
 
Parties immediately upon becoming aware that any Person has made any proposal,
offer, inquiry, or contact with respect to any such transaction, which notice
shall include the identity of all relevant parties and the content of such
communication. The covenants contained in this Section 8.1 shall expire and be
of no further force and effect upon and after any termination of this
Agreement pursuant to Section 12.1. Nothing contained in this Section 8.1
shall prohibit the Ocal Board of Directors from authorizing Ocal to furnish
information to, enter into discussions or negotiations with, or enter into an
agreement with respect to a Business Combination Proposal with, any Person in
connection with an unsolicited proposal in writing by such Person for a
Business Combination with Ocal received by the Ocal Board of Directors after
the date of the Agreement, if, and only to the extent that, (a) the Ocal Board
of Directors, after consultation with its independent legal and financial
advisors and taking into consideration the advice of such advisors, determines
in good faith that such unsolicited proposal may be more favorable to the
holders of Ocal Common Stock than the transactions contemplated by this
Agreement, and (b) prior to furnishing such information to, or entering into
discussions or negotiations with, such Person, Ocal (i) gives the Buying
Parties as promptly as practicable prior written notice of the material terms
of such proposal in reasonable detail and of Ocal's intention to furnish such
information or begin such discussions, and (ii) receives from such Person an
executed confidentiality agreement on substantially the terms as those
contained in Section 8.3 hereof. For purposes of this Agreement, a proposal
for a Business Combination that follows the procedure and satisfies the
criteria set forth above in subdivision (a) as well as subdivisions (b)(i) and
(ii) of this Section is deemed to be a "Business Combination Proposal". As
used herein, the term "Business Combination" shall mean any of the following
involving Ocal: (1) any merger, consolidation, share exchange, business
combination or other similar transaction (other than the Merger); (2) any
sale, lease, exchange, transfer or other disposition (other than a pledge or
mortgage) of 25% or more of the assets of Ocal, in a single transaction or
series of transactions; or (3) the acquisition by a Person or any "group" (as
such term is defined under Section 13(d) of the Securities and Exchange Act of
1934, as amended, and the rules and regulations thereunder) of beneficial
ownership of 33% or more of the shares of the Ocal Common Stock, whether by
tender offer, exchange offer or otherwise.
 
  Section 8.2. Access to Premises and Information. At all times prior to the
Closing, Ocal will, and the Major Securityholders will use their reasonable
best efforts to cause the Company to, during normal business hours and after
reasonable advance notice, permit the Buying Parties and their
representatives, to have full access to their premises, documents, books and
records and to make copies of such financial and operating data and other
information with respect to the Company as the Buying Parties or any of their
representatives shall reasonably request. In addition, the Company and the
Major Securityholders shall cause the Company's management to be available to
the Buying Parties at such times, and from time to time, as the Buying Parties
may reasonably request in connection with the Merger and their review of the
Business. The Company and the Major Securityholders will cause to be delivered
such additional information and copies of documents, books and records
relating to the Company, or the Business as may be reasonably requested by the
Buying Parties, or any of their representatives, including, without
limitation, all quarterly and monthly financial statements (if any) that
become available prior to the Closing.
 
  Section 8.3. Confidentiality Covenant of the Buying Parties. Each of the
Buying Parties will not, and will not permit any of its respective
representatives to, without the prior written consent of Ocal, disclose any
confidential information relating to the Company or the Major Securityholders
furnished to the Buying Parties by or on behalf of the Company or the Major
Securityholders, or use any such information for any purpose otherwise than in
evaluating the Company in connection with the transactions contemplated
hereby; provided, however, that (i) such information may be disclosed to any
of the representatives of the Buying Parties who have a need to know such
information in connection with the transactions contemplated hereby (who shall
be instructed to keep such information confidential in accordance with the
terms of this Section 8.3) and (ii) the information subject to the foregoing
provisions of this sentence shall be deemed not to include any information
known generally in the industry (other than as a result of disclosure in
violation hereof) or any information received by the Buying Parties or any of
its representatives from a third party not bound by a duty of confidentiality
to the Company. In addition, confidential information may be disclosed if
required by legal process or by operation of applicable law; provided,
however, that (i) the disclosing Person shall first promptly
 
                                     A-26
<PAGE>
 
(and, if practicable under the circumstances, prior to disclosure) advise and
consult with the Company and its counsel concerning the information proposed
to be disclosed, (ii) the Company shall have the right to seek an appropriate
protective order or other remedy concerning the confidential information
proposed to be disclosed and the disclosing Person will cooperate with the
Company to obtain such protective order, and (iii) in the event that such
protective order or other remedy is not obtained by the Company within a
reasonable time, the disclosing Person will disclose only that portion of the
confidential information which the disclosing Person is legally required to
disclose, and the disclosing Person will use its best efforts to obtain
assurances that confidential treatment will be accorded to such information.
In the event of any termination of this Agreement pursuant to Article XII,
each of the Buying Parties and their respective representatives will return or
destroy all copies of any written materials in their possession furnished by
or on behalf of the Major Securityholders or the Company, and shall remain
bound by the provisions of this Section. The foregoing provisions of this
Section 8.3 shall (i) supersede all prior confidentiality obligations of the
Buying Parties, (ii) terminate with respect to confidential information
relating to the Company upon the consummation of the Closing and (iii) not
prohibit any retention of records or disclosure required by law or made in
connection with the enforcement of any right or remedy relating to this
Agreement or the transactions contemplated hereby.
 
  Section 8.4. Operation of Business in the Ordinary Course. On and prior to
the Closing Date, except as otherwise required by this Agreement, the Company
will, and the Major Securityholders will cause the Company to, conduct the
Business only in the Ordinary Course of Business and use their respective
commercially reasonable efforts to maintain the value of the Business as a
going concern and the relationships of the Company with customers,
distributors, suppliers, vendors, employees, agents, Governmental Authorities
and others. Without limiting the generality of the foregoing, on and prior to
the Closing Date, the Company shall, and the Major Securityholders shall cause
the Company to, except as may otherwise be consented to in writing by the
Buying Parties, pay accounts payable when due and maintain inventory levels,
all in accordance with prudent business practice and the Ordinary Course of
Business; and the Company will not, and the Major Securityholders will cause

adverse decision or action of the FTC or the Antitrust Division or terminate
this Agreement without further liability or obligation to the Parties.

to such demands. Prior to the Closing, the Major Securityholders and Ocal
shall not, except with the written consent of the Buying Parties, make any

Meeting, contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary in order to make the

which the Special Meeting (or any adjournments or postponements thereof) is
scheduled to occur, an unaudited consolidated balance sheet of Ocal and its
Subsidiaries as of the last day of such month (the "Transaction Balance
Sheet"). For purposes of the Transaction Balance Sheet, there shall be added
to the consolidated stockholders' equity of Ocal and its Subsidiaries (a) the
amount of the Company's total expenditures (including, without limitation,
materials, labor and overhead) between December 31, 1997 and the date of the
Transaction Balance Sheet on the construction and repair of machinery and
equipment used in the Company's Business that had not been previously
capitalized, (b) the fair market value of inventory held by, but not recorded
on the books of, the Company that was either produced by competitors of the
Company or rejected by the Company's customers, and (c) the total amount of
the fees and expenses incurred through the date of the Transaction Balance
Sheet by the Company in connection with the Merger, this Agreement and the
transactions contemplated hereby and thereby but not to exceed $400,000
("Transaction Costs"). The Parties agree that the consolidated stockholders'
equity of Ocal and its Subsidiaries shall not be reduced on account of
inventory that was "specially purchased" and recorded on the Company's books
at standard cost.
 
  (b) T&B and its accountants shall have the right to observe all steps taken
by Ocal and Ernst & Young LLP in connection with the preparation of the
Transaction Balance Sheet and to review all work papers and procedures
relating thereto.
 
  (c) The Transaction Balance Sheet shall identify the "Deficit Amount"
referred to in Section 3.1(e), if any. The "Deficit Amount" shall be zero
unless the amount of the consolidated stockholders' equity on the
 
                                     A-29
<PAGE>
 
Transaction Balance Sheet is less than $15,029,000, in which case the Deficit
Amount shall be difference between $15,029,000 and the consolidated
stockholders' equity on the Transaction Balance Sheet.
 
  Section 8.9. Directors' and Officers' Insurance and Indemnification. T&B
shall, and shall cause the Surviving Corporation to, indemnify each person who
is now, or has been at any time prior to the date hereof, an employee, agent,
director or officer of Ocal or of any of its Subsidiaries, successors and
assigns (individually an "Indemnified Party" and collectively the "Indemnified
Parties"), to the fullest extent required or permitted by law, or any
agreement with Ocal in effect immediately prior to the execution of this
Agreement, with respect to any claim, liability, loss, damage, judgment, fine,
penalty, amount paid in settlement or compromise, cost or expense, including
reasonable fees and expenses of legal counsel (whenever asserted or claimed)
("Indemnified Liability"), based in whole or in part on, or arising in whole
or in part out of, any matter, state of affairs or occurrence existing or
occurring at or prior to the Effective Time whether commenced, asserted or
claimed before or after the Effective Time, including liability arising under
the Securities Act of 1933, as amended, the Exchange Act, or state law. T&B
shall, and shall cause the Surviving Corporation to, maintain in effect for
not less than six years after the Effective Time (a) the current policies of
directors' and officers' liability insurance maintained by Ocal and its
Subsidiaries on the date hereof (provided that T&B may substitute therefor
policies having at least the same coverage, a comparably rated issuer and
containing terms and conditions which are no less advantageous to the persons
currently covered by such policies as insured) with respect to matters
existing or occurring at or prior to the Effective Time; and (b) the currently
existing provisions of Ocal's Certificate of Incorporation and By-laws
regarding the indemnification of directors and officers. T&B shall, and shall
cause the Surviving Corporation to pay in advance all expenses (including fees
and expenses of counsel) that may be incurred by an Indemnified Party in
successfully enforcing the indemnity or other obligations under this
Section 8.9. The rights under this Section 8.9 are in addition to rights that
an Indemnified Party may have under the Charter, By-laws, other similar
organizational documents of Ocal or any of its Subsidiaries or the DGCL. The
rights under this Section 8.9 are contingent upon the occurrence of, and will
survive consummation of, the Merger and are expressly intended to benefit each
Indemnified Party.
 
  Section 8.10. Expenses of Transaction. Except as set forth in Section 12.2,
all fees and expenses incurred in connection with the Merger, this Agreement
and the transactions contemplated hereby and thereby will be paid by the Party
incurring such fees or expenses, whether or not the Merger is consummated. The
Parties acknowledge that the Major Securityholders will bear and pay their
fees and expenses which are unique to their position as majority stockholders
of Ocal.
 
  Section 8.11. Further Assurances. Each Party, upon the request from time to
time of any other Party hereto after the Closing, and without further
consideration, will do each and every act and thing as may be reasonably
necessary or reasonably requested to consummate the transactions contemplated
hereby in an orderly fashion. In the event that a lease, contract or license
does not expressly permit the Company to maintain its rights and obligations
thereunder after the Closing Date, or the Company has not obtained the
necessary written consents under any specific lease, contract or license prior
to the Closing Date, the Major Securityholders shall cooperate with T&B and
the Company in any reasonable arrangement not requiring any out-of-pocket
expense by the Major Securityholders (unless reimbursed by T&B) designed to
provide the Company with the material benefits to have been received by the
Company if the consent or approval had been obtained.

entire agreement among the parties hereto pertaining to the subject matter
hereof and supersedes all prior agreements, understandings, negotiations and
discussions, whether oral or written, of the parties with respect to such
subject matter. No waiver of any provision of this Agreement shall be deemed

by the Buying Parties, by the Buying Parties, (ii) in the case of a waiver by
the Major Securityholders, by the Major Securityholders and (iii) in the case
of a waiver by Ocal, by Ocal.

modify this Agreement except in such manner as may be agreed upon by a written
instrument: (i) in the case of any amendment prior to the Closing, executed by
each Buying Party, Ocal and Major Securityholders who hold a majority of the

hereto intend that each representation, warranty and covenant contained herein
shall have independent significance. If any Party has breached any
representation, warranty or covenant contained herein in any respect, the fact

that such Party is in breach of the first representation, warranty or
covenant.

description of any item, matter or document in any Schedule hereto nor the
furnishing or availability for review of any document shall be construed to
modify, qualify or disclose an exception to any representation or warranty of
any Party made herein or in connection herewith, except to the extent that
such representation or warranty specifically refers to such Schedule and such
modification, qualification or exception is described in such Schedule;
provided, however, that with respect to any matter that is clearly disclosed
in any Section of this Agreement or in any Schedule hereto in such a way as to
make its relevance to the information called for by another Section of this

deemed to have been included in response to such other Section or Schedule,

under applicable law, be invalid or unenforceable in any respect, such
provision shall (to the extent permitted under applicable law) be construed by
modifying or limiting it so as to be valid and enforceable to the maximum
extent compatible with, and possible under, applicable law. The provisions
hereof are severable, and in the event any provision hereof should be held

this Agreement shall be binding upon and shall inure to the benefit of the
Parties hereto and their respective transferees, successors and assigns (each

party hereto for all purposes hereof); provided, however, this Agreement may
only be assigned by a Party with the written consent of the other Parties.

October 6, 1998
 
To the Board of Directors
OCAL, Inc.
 
Dear Sirs:
 
  We understand that OCAL, Inc. ("OCAL" or the "Company") will enter into an
Agreement and Plan of Merger with Thomas & Betts Corporation, pursuant to
which the stockholders of OCAL (the "Stockholders") will receive an aggregate
consideration of approximately $20.3 million for their equity interest in
OCAL. Such transaction and all related transactions are referred to
collectively herein as the "Transaction."
 
  You have requested our opinion (the "Opinion") as to the matters set forth
below. The Opinion does not address the Company's underlying business decision
to effect the Transaction. We have not been requested to, and did not, solicit
third party indications of interest in acquiring all or any part of the
Company. Furthermore, at your request, we have not negotiated the Transaction
or advised you with respect to alternatives to it.
 
  In connection with this Opinion, we have made such reviews, analyses and
inquiries as we have deemed necessary and appropriate under the circumstances.
Among other things, we have:
 
 .  reviewed the Company's audited financial statements for the five fiscal
   years ended December 31, 1997 and unaudited financial statements for the
   quarters ended June 30, 1998, March 31, 1998 and June 30, 1997;
 
 .  reviewed the company's unaudited internal consolidated financial statements
   for the eight month period ended August 31, 1998, which the Company's
   management has identified as being the most current financial statements
   available as of the valuation date;
 
 .  met with certain members of the senior management of the Company to discuss
   the operations, financial condition, future prospects and projected
   operations and historical performance of the Company;
 
 .  visited the Company's production plant in Mobile, Alabama on September 17,
   1998;
 
 .  reviewed projections prepared by the Company's management with respect to
   the Company for the years ended December 31, 1998 and December 31, 1999;
 
 .  reviewed the historical market prices and trading volume for the Company's
   publicly traded securities;
 
 .  reviewed certain other publicly available financial data for certain
   companies we deem comparable to the Company, and publicly available prices
   and premiums paid in other transactions that we considered similar to the
   Transaction;
 
 .  reviewed a draft of the Agreement and Plan of Merger among Thomas & Betts
   Corporation, OCAL Acquisition Corp., OCAL, Inc. and certain Stockholders of
   OCAL, Inc., dated September 30, 1998;
 
 .  reviewed a draft of the Agreement and Plan of Merger among the Company,
   Robroy Industries, Inc. and Excelsior Acquisition, Inc., dated September
   29, 1998;
 
 .  reviewed a letter dated October 2, 1998 conveying a revised proposal from
   Robroy Industries, Inc.; and
 
 .  conducted such other studies, analyses, and inquiries as we have deemed
   appropriate.

To The Board of Directors
OCAL, Inc.
October 6, 1998
 
  We have relied upon and assumed, without independent verification, that the
financial forecasts and projections provided to us have been reasonably
prepared and reflect the best currently available estimates of the future
financial results and condition of the Company, and that there has been no
material change in the assets, financial condition, business or prospects of
the Company since the date of the most recent financial statements made
available to us.
  We have not independently verified the accuracy and completeness of the
information supplied to us with respect to the Company and do not assume any
responsibility with respect to it. Except as described above, we have not made
any physical inspection or independent appraisal of any of the properties or
assets of the Company. Our opinion is necessarily based on business, economic,
market and other conditions as they exist and can be evaluated by us at the
date of this letter.
 
  Based upon the foregoing, and in reliance thereon, it is our opinion that
the consideration to be received by the Stockholders of the Company in
connection with the Transaction is fair to them from a financial point of
view.
 
  This Opinion is furnished for your benefit and may not be relied upon by any
other person without our express, prior written consent. Houlihan Lokey
consents to any references to, description of and inclusion of, the text of
this Opinion in a proxy statement to be filed with the Securities and Exchange
Commission and delivered to the Company's Stockholders in connection with the
Transaction. This Opinion is delivered to each recipient subject to the
conditions, scope of engagement, limitations and understandings set forth in
this Opinion and our engagement letter, and subject to the understanding that
the obligations of Houlihan Lokey in the Transaction are solely corporate
obligations, and no officer, director, employee, agent, shareholder or
controlling person of Houlihan Lokey shall be subjected to any personal
liability whatsoever to any person, nor will any such claim be asserted by or
on behalf of you or your affiliates.

  262 APPRAISAL RIGHTS.--(a) Any stockholder of a corporation of this State
who holds shares of stock on the date of the making of a demand pursuant to
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation,
who has otherwise complied with subsection (d) of this section and who has
neither voted in favor of the merger or consolidation nor consented thereto in
writing pursuant to (S)228 of this title shall be entitled to an appraisal by
the Court of Chancery of the fair value of the stockholder's shares of stock
under the circumstances described in subsections (b) and (c) of this section.
As used in this section, the word "stockholder" means a holder of record of
stock in a stock corporation and also a member of record of a nonstock
corporation; the words "stock" and "share" mean and include what is ordinarily
meant by those words and also membership or membership interest of a member of
a nonstock corporation; and the words "depository receipt" mean a receipt or
other instrument issued by a depository representing an interest in one or
more shares, or fractions thereof, solely of stock of a corporation, which
stock is deposited with the depository.
 
  (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to
be effected pursuant to (S)251 (other than a merger effected pursuant to
(S)251 (g) of this title), (S)252, (S)254, (S)257, (S)258, (S)263 or (S)264 of
this title:
 
    (1) Provided, however, that no appraisal rights under this section shall
  be available for the shares of any class or series of stock, which stock,
  or depository receipts in respect thereof, at the record date fixed to
  determine the stockholders entitled to receive notice of and to vote at the
  meeting of stockholders to act upon the agreement of merger or
  consolidation, were either (i) listed on a national securities exchange or
  designated as a national market system security on an interdealer quotation
  system by the National Association of Securities Dealers, Inc. or (ii) held
  of record by more than 2,000 holders; and further provided that no
  appraisal rights shall be available for any shares of stock of the
  constituent corporation surviving a merger if the merger did not require
  for its approval the vote of the stockholders of the surviving corporation
  as provided in subsection (f) of (S)251 of this title.
 
    (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
  under this section shall be available for the shares of any class or series
  of stock of a constituent corporation if the holders thereof are required
  by the terms of an agreement of merger or consolidation pursuant to
  (S)(S)251, 252, 254, 257, 258, 263 and 264 of this title to accept for such
  stock anything except:
 
      a. Shares of stock of the corporation surviving or resulting from
    such merger or consolidation, or depository receipts in respect
    thereof;
 
      b. Shares of stock of any other corporation, or depository receipts
    in respect thereof, which shares of stock (or depository receipts in
    respect thereof) or depository receipts at the effective date of the
    merger or consolidation will be either listed on a national securities
    exchange or designated as a national market system security on an
    interdealer quotation system by the National Association of Securities
    Dealers, Inc. or held of record by more than 2,000 holders;
 
      c. Cash in lieu of fractional shares or fractional depository
    receipts described in the foregoing subparagraphs a. and b. of this
    paragraph; or
 
      d. Any combination of the shares of stock, depository receipts and
    cash in lieu of fractional shares or fractional depository receipts
    described in the foregoing subparagraphs a., b. and c. of this
    paragraph.
 
    (3) In the event all of the stock of a subsidiary Delaware corporation
  party to a merger effected under (S)253 of this title is not owned by the
  parent corporation immediately prior to the merger, appraisal rights shall
  be available for the shares of the subsidiary Delaware corporation.
 
                                      C-1

  (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets
of the corporation. If the certificate of incorporation contains such a
provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.
 
  (d) Appraisal rights shall be perfected as follows:
 
    (1) If a proposed merger or consolidation for which appraisal rights are
  provided under this section is to be submitted for approval at a meeting of
  stockholders, the corporation, not less than 20 days prior to the meeting,
  shall notify each of its stockholders who was such on the record date for
  such meeting with respect to shares for which appraisal rights are
  available pursuant to subsection (b) or (c) hereof that appraisal rights
  are available for any or all of the shares of the constituent corporations,
  and shall include in such notice a copy of this section. Each stockholder
  electing to demand the appraisal of his shares shall deliver to the
  corporation, before the taking of the vote on the merger or consolidation,
  a written demand for appraisal of his shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of his shares. A proxy or vote against the merger or
  consolidation shall not constitute such a demand. A stockholder electing to
  take such action must do so by a separate written demand as herein
  provided. Within 10 days after the effective date of such merger or
  consolidation, the surviving or resulting corporation shall notify each
  stockholder of each constituent corporation who has complied with this
  subsection and has not voted in favor of or consented to the merger or
  consolidation of the date that the merger or consolidation has become
  effective; or
 
    (2) If the merger or consolidation was approved pursuant to (S)228 or
  (S)253 of this title, each constituent corporation, either before the
  effective date of the merger or consolidation or within ten days
  thereafter, shall notify each of the holders of any class or series of
  stock of such constituent corporation who are entitled to appraisal rights
  of the approval of the merger or consolidation and that appraisal rights
  are available for any or all shares of such class or series of stock of
  such constituent corporation, and shall include in such notice a copy of
  this section; provided that, if the notice is given on or after the
  effective date of the merger or consolidation, such notice shall be given
  by the surviving or resulting corporation to all such holders of any class
  or series of stock of a constituent corporation that are entitled to
  appraisal rights. Such notice may, and, if given on or after the effective
  date of the merger or consolidation, shall, also notify such stockholders
  of the effective date of the merger or consolidation. Any stockholder
  entitled to appraisal rights may, within 20 days after the date of mailing
  of such notice, demand in writing from the surviving or resulting
  corporation the appraisal of such holder's shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of such holder's shares. If such notice did not notify
  stockholders of the effective date of the merger or consolidation, either
  (i) each such constituent corporation shall send a second notice before the
  effective date of the merger or consolidation notifying each of the holders
  of any class or series of stock of such constituent corporation that are
  entitled to appraisal rights of the effective date of the merger or
  consolidation or (ii) the surviving or resulting corporation shall send
  such a second notice to all such holders on or within 10 days after such
  effective date; provided, however, that if such second notice is sent more
  than 20 days following the sending of the first notice, such second notice
  need only be sent to each stockholder who is entitled to appraisal rights
  and who has demanded appraisal of such holder's shares in accordance with
  this subsection. An affidavit of the secretary or assistant secretary or of
  the transfer agent of the corporation that is required to give either
  notice that such notice has been given shall, in the absence of fraud, be
  prima facie evidence of the facts stated therein. For purposes of
  determining the stockholders entitled to receive either notice, each
  constituent corporation may fix, in advance, a record date that shall be
  not more than 10 days prior to the date the notice is given, provided, that
  if the notice is given on or after the effective date of the merger or
  consolidation, the record date shall be such effective date. If no record
  date is fixed and the notice is given prior to the effective date, the
  record date shall be the close of business on the day next preceding the
  day on which the notice is given.
 
                                      C-2

  (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied
with subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholders. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger
or consolidation, any stockholder shall have the right to withdraw his demand
for appraisal and to accept the terms offered upon the merger or
consolidation. Within 120 days after the effective date of the merger or
consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which
demands for appraisal have been received and the aggregate number of holders
of such shares. Such written statement shall be mailed to the stockholder
within 10 days after his written request for such a statement is received by
the surviving or resulting corporation or within 10 days after expiration of
the period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.
 
  (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.
 
  (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled
to appraisal rights. The Court may require the stockholders who have demanded
an appraisal for their shares and who hold stock represented by certificates
to submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as
to such stockholder.
 
  (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court
may, in its discretion, permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on
the list filed by the surviving or resulting corporation pursuant to
subsection (f) of this section and who has submitted his certificates of stock
to the Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that he is not entitled to
appraisal rights under this section.
 
  (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and the case of holders of
shares represented by certificates upon the surrender to the corporation of
the certificates representing such stock. The Court's decree may be enforced
as other decrees in the Court of
 
                                      C-3
<PAGE>
 
Chancery may be enforced, whether such surviving or resulting corporation be a
corporation of this State or of any state.
 
  (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
  (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection
(d) of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation);
provided, however, that if no petition for an appraisal shall be filed within
the time provided in subsection (e) of this section, or if such stockholder
shall deliver to the surviving or resulting corporation a written withdrawal
of his demand for an appraisal and an acceptance of the merger or
consolidation, either within 60 days after the effective date of the merger or
consolidation as provided in subsection (e) of this section or thereafter with
the written approval of the corporation, then the right of such stockholder to
an appraisal shall cease. Notwithstanding the foregoing, no appraisal
proceeding in the Court of Chancery shall be dismissed as to any stockholder
without the approval of the Court, and such approval may be conditioned upon
such terms as the Court deems just.
 
  (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.
