ITEM 1.  CHANGES IN CONTROL OF REGISTRANT

     On October 6, 1998, Ocal, Inc., a Delaware corporation (the "Registrant"),
Thomas & Betts Corporation, a Tennessee corporation ("T&B"), Ocal Acquisition
Corp., a Delaware corporation and wholly-owned subsidiary of T&B ("Sub"), and
certain stockholders of the Registrant executed an Agreement and Plan of Merger
(the "Merger Agreement") relating to the acquisition of Registrant by T&B.
Pursuant to the Merger Agreement and subject to the terms and conditions set
forth therein, Sub will merge into Registrant (the "Merger"), whereupon
Registrant will become a wholly-owned subsidiary of T&B.  Under the Merger
Agreement, T&B's aggregate purchase price for Registrant is approximately $20.3
million in cash.

     At the Effective Time (as defined in the Merger Agreement) of the Merger,
each issued and outstanding share of Common Stock, par value $.001 per share, of
Registrant will be converted into the right to receive $3.54 in cash, subject to
reduction under certain circumstances if and to the extent Registrant's
stockholders' equity at the end of the month prior to the consummation of the
merger is less than Registrant's stockholders' equity at August 31, 1998.  The
Registrant does not believe, based on its current operating results, that there
will be any such purchase price reduction.  The Merger Agreement also provides
that the Registrant may terminate the Merger Agreement without consummating the
Merger if the amount of such purchase price reduction would exceed $1.5 million
(approximately $0.26 per share).  The foregoing per share amounts are based on
5,681,000 shares of Common Stock outstanding as of the date hereof.

     The Merger Agreement also contains voting provisions, pursuant to which,
among other things, Ilan Bender (Registrant's Chairman, Chief Executive Officer
and President), who individually and through certain entities controls
approximately 54% of Registrant's outstanding stock, has agreed to vote all
shares he controls in favor of the Merger.  Mr. Bender has also agreed to place
$450,000 of his personal proceeds from the Merger in a two-year escrow to
indemnify T&B for certain potential post-closing liabilities of the Registrant.
Mr. Bender will also provide consulting services to T&B for one year after the
consummation of the Merger for total payments of $100,000.

     The consummation of the Merger is subject to, among other things, (i)
approval by the stockholders of Registrant and (ii) expiration or termination of
applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976.  Registrant has not yet scheduled a date for its stockholders
meeting.

     A copy of the Merger Agreement is filed herewith as Exhibit 2.1.  The
foregoing descriptions are qualified in their entirety by reference to the full
text of such Exhibit.

     On October 7, 1998, the parties issued a joint press release announcing the
execution of the Merger Agreement.  A copy of the press release is attached as
Exhibit 99.1 hereto and the contents thereof are hereby incorporated herein by
reference.

     This Current Report on Form 8-K contains certain "forward-looking
statements" within the meaning of the Private Securities Litigation Reform Act
of 1995 which involve risks and uncertainties.  Actual results could differ
materially from those anticipated in these 

                                      -2-
<PAGE>
 
forward-looking statements as a result of certain factors, including, without
limitation, a failure of the Registrant's operating results to continue at
current levels, as well as the factors set forth in the Registrant's most recent
Annual Report on Form 10-K and other Securities and Exchange Commission filings.

                           -------------------------
                                        
          Section 3.1.  MANNER OF CONVERTING OCAL SHARES.  At the Effective 
          -----------   --------------------------------
Time, by 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.

<PAGE>
 
               (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 

                                       14
<PAGE>
 
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.

                    --------------------------------------
                                        
     In order to induce the Buying Parties to enter into and perform this
Agreement and to consummate the transactions contemplated hereby, Ocal makes the
following representations and warranties to the Buying Parties:

          SECTION 6.1.   CORPORATE MATTERS, ETC.
          -----------    -----------------------

               (a)  ORGANIZATION, POWER AND STANDING.  Each of Ocal and its
Subsidiaries are corporations duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization or incorporation,
and have all requisite corporate power and authority to enter into and perform
their obligations under this Agreement, to carry on the Business as currently
conducted, and to consummate the transactions contemplated hereby. Each of 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
                                                                       --------
6.1(a) contains a correct and complete list of each jurisdiction where Ocal 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

                                       19

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

made by Ocal, and to comply with State securities laws, no notices, reports or
other filings are required to be made by Ocal with, nor are any consents,
registrations, approvals, permits or authorizations required to be 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

Company, (iv) the imposition of any Lien upon or the forfeiture of any material
Asset (including, without limitation, any material Asset held under a

default under any Contractual Obligation of the Company, or the requirement that
any consent under or waiver of any Lease or other Contractual Obligation be

Material Adverse Effect.

               (d)  CAPITALIZATION.  The authorized capital stock of Ocal

          SECTION 6.2.  OCAL REPORTS

               (a)  SEC REPORTS.  Ocal has delivered or made available to T&B

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, 1998, and June
30, 1998, each in the form (including exhibits, annexes and any 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

any material transaction other than according to, the Ordinary Course of

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

                                       21
<PAGE>
 
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

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

which have had or resulted or are reasonably likely to have or result in any

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)

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

limitation, all amendments. There is no Contractual Obligation under which the
Company is liable as lessor with respect to any real property or Equipment.

     conditional use permits of the jurisdictions in which the Leased Property

                    (ii)   With respect to the Leased Properties, (A) the
     Company is in peaceful and undisturbed possession of the property under the
     applicable Property Lease, and (B) the Company has not received any written

     any Contractual Obligations that preclude or restrict the ability to use
     the premises for the purposes for, and in the manner in, which they are
     currently being used, or of any cancellation or termination under any
     option or right reserved to the lessor under the applicable Property Lease
     or any notice of default under the applicable Property Lease, with such

     Properties, (ii) any violation of any Permit, or (iii) any eminent domain,

     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.

                    (vi)   The Company has right of ingress to and egress from
     the Leased Properties adequate for the operations of the Company as
     currently conducted thereon.

                    (vii)  To the Company's knowledge, with respect to the
     Property Leases: (a) no event has occurred which (with the giving of notice
     or the passage 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

     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

     independent third parties.

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

considered in a proceeding at law or in equity).  To the Company's knowledge, no

continuing, and no event has occurred which with notice or lapse of time would

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

has never had, any self-insurance arrangements other than insurance deductibles.

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

               (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

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 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.

                                  ARTICLE VII

             REPRESENTATIONS AND WARRANTIES OF THE BUYING PARTIES
             ----------------------------------------------------
                                        
    In order to induce Ocal and each Major Securityholder to enter into and
perform this Agreement and to consummate the transactions contemplated hereby,
the Buying Parties, jointly and severally, represent and warrant to Ocal and the
Major Securityholders as follows:

       SECTION 7.1.  CORPORATE MATTERS.
       -----------   -----------------

          (a)  ORGANIZATION, POWER AND STANDING.  Each Buying Party is a
corporation duly organized, validly existing and in good standing under the laws
of Tennessee (in the case of T&B) and Delaware (in the case of Acquisition
Subsidiary) and has all requisite power and authority, corporate and otherwise,
to enter into this Agreement and all Closing Agreements to which it is a party
to carry out and perform its obligations hereunder and thereunder and to
consummate the transactions contemplated hereby and thereby. Each of T&B 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 could not reasonably be expected to
have a Material Adverse Effect on T&B and its Subsidiaries taken as a whole.

          (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
Preferred Stock, $.10 par value, none of which are outstanding. All of the
issued and outstanding capital stock of Acquisition Subsidiary is, and at the
Effective Time will be owned by T&B, and there are no other (i) shares of
capital stock or other voting security of Acquisition Subsidiary, (ii) Equity
Securities of Acquisition Subsidiary, and (iii) obligations of Acquisition
Subsidiary to issue, any capital stock, voting security or securities
convertible into or exchangeable for capital stock or voting securities of
Acquisition Subsidiary. Acquisition Subsidiary has not conducted any business
prior to the date hereof and has no, and prior to the Effective Time will have
no, assets, liabilities or obligations of any nature other than those incident
to its formation and pursuant to this Agreement and the Merger and other
transactions contemplated by this Agreement.

Closing Agreements to which it is or will be a party, and the transactions
contemplated hereby and thereby, have been or will be duly authorized, and this
Agreement and all Closing Agreements to which it is or will be a party have been
or will be duly executed and delivered by each Buying Party, and are Enforceable
against each Buying Party. Except for filings or notices under the Hart-Scott
Rodino Act and the Exchange Act as required by ARTICLE VIII and to comply with
                                               ------------
state securities laws, no approval, consent, waiver, authorization or other
order of, and no declaration, filing, registration, qualification or recording
with, any Governmental Authority or any other Person, including, without
limitation, any party to any Contractual Obligation of either Buying Party, is
required to be obtained or made by or on behalf of either Buying Party in
connection with the execution, delivery or performance of this Agreement and the
consummation of the transactions 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
performance of any obligation under any material Contractual Obligation of
either Buying Party, (iv) the imposition of any Lien upon or the forfeiture of
any material Asset of either Buying Party (including, without limitation, any
material Asset held under any Contractual Obligation of either Buying Party),
(v) a material breach of or a material default under any Contractual Obligation
of either Buying Party, or the requirement that any consent under or a waiver of
any Lease or other Contractual Obligation be obtained, except in the case of
items that could not reasonably be expected to have a Material 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
consummation of, or otherwise relates to, this Agreement, or any of 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.

       SECTION 7.5.  SUFFICIENT FUNDS.  Either T&B or the Acquisition
       -----------   ----------------                                  
Subsidiary has sufficient funds available (through existing credit arrangements
or otherwise) to acquire all of the Ocal Equity Securities outstanding pursuant
to the Merger and this Agreement and to pay all fees and expenses related to the
transactions contemplated by this Agreement for which T&B or the Acquisition
Subsidiary is responsible.

this Agreement, when taken as a whole, do not or will not contain any untrue
statement of a material fact relating to T&B or the Acquisition Subsidiary or
their Affiliates.  This Agreement (including, without limitation, the Exhibits
and Schedules hereto) does not, considered as a whole, omit to state a material
fact necessary in order to make the statements contained herein not misleading.

                       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
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, 

                                       38
<PAGE>
 
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

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
       -----------   ----------------------------------

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

Parties, or any of their representatives, including, without limitation, all
quarterly and monthly financial statements (if any) that become available prior

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 

                                       39
<PAGE>
 
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 (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.

The Parties shall each furnish the other with such information as either may
reasonably request to make such filings.  In the event that the Antitrust
Division brings suit seeking to prevent or restrain the transactions

       SECTION 8.8.  PREPARATION OF TRANSACTION BALANCE SHEET.
       ------------  ----------------------------------------   

          (a) Ocal shall cause Ernst & Young LLP to prepare, as soon as
practicable after the last day of the calendar month immediately preceding the
month in 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 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.

       -----------   ------------------------------------------------------    
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 

                                       44

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

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.

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

that there exists any other representation, warranty or covenant relating to the
same subject matter 

                                       54

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 Agreement
or another Schedule hereto reasonably apparent, such matter shall be deemed to
have been included in response to such other Section or Schedule,

would, 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 invalid or
unenforceable in any respect, it shall not invalidate, render unenforceable or
otherwise affect any other provision hereof.
