                                     ANNEX A
                           DESCRIPTION OF TRANSACTIONS

            SUT Acquisition Corp. ("SUT"), a wholly owned subsidiary of Superior
TeleCom Inc. ("Superior"), will purchase up to 22,562,135 shares of the common
stock of Essex International, $.01 par value per share (the "Common Stock"),
pursuant to a tender offer for such shares of Common Stock commenced on or about
October 28, 1998 (the "Offer"), as such Offer is further described in the Offer
to Purchase dated October 28, 1998 (the "Offer to Purchase"), a copy of which is
annexed hereto. The Offer is being made pursuant to an Agreement and Plan of
Merger dated as of October 21, 1998, by and among Superior, SUT and Essex
International, whereby subsequent to the purchase of the Common Stock pursuant
to the Offer, SUT will be merged with and into Essex International, and Essex
International will continue as the surviving corporation and become a wholly
owned subsidiary of Superior (the "Merger"), as such Merger is further described
in the Offer to Purchase.

            The total amount of funds required by SUT to consummate the Offer
and the Merger (including the refinancing of certain indebtedness of Superior
and Essex International) and to pay related fees and expenses is estimated to be
approximately $1.30 billion. SUT will obtain all of such funds from Superior.
Superior currently intends to provide such funds from loans available pursuant
to a (i) Senior Secured Credit Facility (the "Senior Credit Facility") to be
entered into by Superior/Essex Corp., a newly formed Delaware corporation and
wholly-owned subsidiary of Superior ("SEC"), Essex Group, Inc., a Michigan
corporation and a subsidiary of Essex International ("Essex Group"), certain
subsidiaries of Superior and Essex as guarantors, various lenders, Merrill Lynch
& Co., as documentation agent ("Merrill"), Fleet National Bank, as syndication
agent ("Fleet"), and Bankers Trust Company, as administrative agent ("Bankers
Trust") and (ii) Senior Subordinated Credit Facility (the "Subordinated Credit
Facility") to be entered into by SEC, certain subsidiaries of Superior
(including Essex International and Essex Group) as guarantors, various lenders
and Bankers Trust. Superior has received a commitment letter dated October 21,
1998 (the "Commitment Letter") in which Bankers Trust has agreed, subject to
certain conditions, to provide the credit facilities in an aggregate amount of
up to $1.45 billion in order to finance the acquisition of Essex International,
to refinance certain existing indebtedness of Superior and Essex International,
to pay related fees and expenses and to provide for the working capital
requirements of Superior or its subsidiaries (including Essex International).

            The following is a summary of the anticipated material terms and
conditions of the approximately $1.15 billion Senior Credit Facility and is
subject to the detailed provisions of the loan agreement and various related
documents to be negotiated and entered into in connection with the Senior Credit
Facility:

            o The Senior Credit Facility will be comprised of two tranches of
      term loans and a revolving credit facility. Interest on amounts
      outstanding under the Senior Credit Facility will be based upon either (i)
      the Federal Reserve reported certificate of deposit rate, Bankers Trust's
      prime lending rate or an adjusted certificate of deposit rate or (ii) the
      Euro rate

<PAGE>

      plus, in each case, an applicable margin, a variable component which, in
      certain circumstances, will be subject to adjustment based on the leverage
      ratio maintained by SEC. SEC and Essex Group will also pay Bankers Trust
      underwriting and administrative fees, reimburse certain expenses and
      provide certain indemnities. The two tranches of term loans will have five
      and one-half and seven year terms, and the revolving credit facility will
      have a five and one-half year term. Each of the term loans will require
      periodic mandatory amortization payments.

            o The obligations of each of SEC and Essex Group under the Senior
      Credit Facility will be unconditionally guaranteed by the other party and
      their respective obligations will be guaranteed by certain of their
      respective subsidiaries. The indebtedness incurred under the Senior Credit
      Facility will also be secured by a first priority lien on substantially
      all the assets of SEC, Essex Group and their subsidiaries.

            o SEC, Essex Group and certain of their respective subsidiaries will
      be subject to certain customary affirmative and negative covenants under
      the Senior Credit Facility, including, without limitation, covenants that
      restrict, subject to specified exceptions, (i) the incurrence of
      additional indebtedness and other obligations, (ii) mergers and
      acquisitions, (iii) asset sales, (iv) the granting of liens, (v)
      prepayment or repurchase of other indebtedness, (vi) engaging in
      transactions with affiliates, (vii) capital expenditures, (viii) the
      making of investments and (ix) dividends and other payments with respect
      to equity interests.

            Concurrently with the closing of the Senior Credit Facility, SEC
will also enter into the $200,000,000 Subordinated Credit Facility. The
following is a summary of the anticipated material terms and conditions of the
Subordinated Credit Facility and is subject to the detailed provisions of the
loan agreement and various related documents to be negotiated and entered into
in connection with the Subordinated Credit Facility:

            o The Subordinated Credit Facility will be a general unsecured
      obligation of Superior which will rank pari passu in right of payment with
      all future senior subordinated indebtedness and senior to all other
      subordinated indebtedness. The Subordinated Credit Facility will be
      guaranteed by certain subsidiaries of Superior (including Essex), on a
      joint and several basis. The Subordinated Credit Facility will mature in
      2006 and will be redeemable at the option of SEC at any time after
      closing. Upon a change of control (as defined in the Subordinated Credit
      Facility), SEC will be required to offer to repurchase the Subordinated
      Credit Facility indebtedness at a purchase price equal to 101% of the
      principal amount thereof, plus accrued interest thereon to the date of
      repurchase. Mandatory prepayments will required from: (i) the net proceeds
      from issuances of debt and (ii) the net proceeds from equity issuances
      with customary exceptions to be agreed upon, in each case to the extent
      not required to repay senior indebtedness (i.e., the Senior Credit
      Facility). Proceeds of the Subordinated Credit Facility will be used to
      finance the Offer, to refinance certain existing indebtedness of SEC and
      Essex International and to pay related fees and expenses.


                                       2

            o Interest on the Subordinated Credit Facility will be payable
      quarterly. For the first six months after the borrowing date, interest
      will be based upon LIBOR plus 4.25% and if LIBOR rate loans are not
      available, the alternate base rate (the higher of prime or 1/2 of 1% over
      the Federal Funds Rate) plus 3.25%. Upon the six month anniversary of the
      borrowing date, interest will be based upon LIBOR plus 4.50% and if LIBOR
      rate loans are not available, the alternate base rate plus 3.50%. Upon the
      12 month anniversary of the borrowing date, interest will be based upon
      LIBOR plus 5.00% and if LIBOR rate loans are not available, the alternate
      base rate plus 4.00%. After the interest rate increase on the 12 month
      anniversary of the borrowing date, the interest rate will increase by
      0.25% per quarter, but the maximum interest rate will be LIBOR plus 5.50%
      and if LIBOR rate loans are not available, the alternate base rate plus
      4.50%.

            o The Subordinated Credit Facility will contain a cross-acceleration
      to the Senior Credit Facility and will also contain covenants limiting the
      ability of SEC and its subsidiaries (including Essex International) to,
      among other things, pay dividends or make other restricted payments, make
      investments, incur additional indebtedness, permit liens, enter into any
      consolidation, merger, conveyance or lease transactions, make asset sales,
      enter into transactions with affiliates and engage in unrelated lines of
      business.

            Subsequent to the transactions described above, Essex may be merged
with or into either Superior or any subsidiary of Superior (the "Post-Closing
Merger"). In connection with the Merger, The Alpine Group, Inc., a Delaware
corporation that owns 50.1% of Superior, will receive a $10,000,000 fee in
respect of financial advisory services rendered to Superior in connection with
the acquisition of Essex International. The transactions described above (the
"Transactions") are more particularly described in the Offer to Purchase, a copy
of which is attached hereto.
