                              CONVERSION OF SHARES
 
     2.1  Conversion of Company Stock. At the Effective Time, by virtue of the
Merger and without any action required on the part of Index, the Company, the
Merger Sub or any holder of capital stock of any of them:
 
          (a) Subject to the limitations contained herein, each outstanding
     share of Sepco Class A Common Stock will be converted into the right to
     receive 16 shares of Index Common Stock. Each outstanding share of Sepco
     Class B Common Stock will be converted into the right to receive 18.1232
     shares of Index Common Stock. Further, each outstanding share of Sepco
     Class A Convertible Preferred Stock will be converted into the right to
     receive one share of Index Series B Convertible Preferred Stock. Finally,
     each outstanding share of Sepco Preferred Stock will be converted into the
     right to receive one share of Index Series A Preferred Stock. The Sepco
     Preferred Stock, Sepco Class A Convertible Preferred Stock, Sepco Class A
     Common Stock and Sepco Class B Common Stock shall be collectively referred
     to as "Company Stock"). The Index Common Stock, Index Series A Preferred

          (b) All shares of common stock of the Merger Sub issued and

     cease to be outstanding.

an outstanding certificate or certificates representing the Company Stock shall

issued to the holder of such certificate(s) a new certificate representing
shares of Index Stock in accordance with Section 2.1, less any amount required
to be withheld under applicable federal, state or local tax requirements, and
the surrendered certificate(s) shall be cancelled. Until so surrendered and

shares of Index Stock in accordance with Section 2.1, without interest and less
any tax withholding.
 
     2.3  Fractional Shares. No fractional shares of Company Common Stock shall
be issued in the Merger. In lieu thereof, all fractional shares of Company

entitled to receive as a result of the Merger shall be automatically converted
into the right to receive an amount of cash to be determined by multiplying
$0.58 by the fraction of a share of Company Common Stock to which such holder
would otherwise have been entitled. Further, all fractional shares of Company
Common Stock that a holder of Sepco Class B Common Stock would otherwise be
entitled to receive as a result of the Merger shall be automatically converted
into the right to receive an amount of cash to be determined by multiplying
$0.58 by the fraction of a share of Company Common Stock to which such holder
would otherwise be entitled. Fractional shares of Company Convertible Preferred
Stock and Company Preferred Stock, if any, will be issued in the Merger to the
holders of Sepco Class A Convertible Preferred Stock and Sepco Preferred Stock,
respectively.
 
     2.4  Dissenting Shares. Each share of Company Stock issued and outstanding
immediately prior to the Effective Time not voted in favor of the Merger, the
holder of which has given written notice of the exercise of dissenter's rights
and has perfected such rights as required by the TBCA is herein called a
"Dissenting Share." Dissenting Shares shall not be converted into or represent
the right to receive shares of Index Stock pursuant to this Section 2 and shall
be entitled only to such rights as are available to such holder pursuant to the
TBCA,
 
                                        2
   7
 
unless the holder thereof shall have withdrawn or forfeited his dissenter's
rights. Each holder of Dissenting Shares shall be entitled to receive the value
of such Dissenting Shares held by him in accordance with the applicable
provisions of the TBCA. Index will promptly pay to any holder of Dissenting
Shares such amount as such holder shall be entitled to receive in accordance
with the applicable provisions of the TBCA. If any holder of Dissenting Shares
shall effectively withdraw or forfeit his dissenter's rights under the TBCA,
such Dissenting Shares shall be converted into the right to receive shares of
Index Stock in accordance with this Section 2.

     4.10  Undisclosed Liabilities. The Company has no material liability or
obligation of any nature whatsoever, either direct or indirect, matured or

caused to be filed all returns, reports or similar statements (including any

                                        6
   11
 
including, without limitation, all information returns, claims for refunds,
amended returns and declarations of estimated tax (collectively, the "Tax
Returns"). For the purpose of this Agreement, "tax" shall include any federal,
state, local or foreign income, gross receipts, windfall profits, severance,
property, production, sales, use, license, excise, franchise, employment,
payroll, withholding, alternative or add-on minimum, ad valorem, transfer, stamp
or environmental tax, or any other tax or similar assessment or charge, together
with any interest or penalty, addition to tax or additional amount imposed by
any governmental authority. The Company has paid in full or fully reserved
against in the Financial Statements all taxes, interest, penalties, assessments
and deficiencies due or claimed to be due by it to foreign, federal, state or
local taxing authorities. All Tax Returns are complete and accurate and disclose
all taxes required to be paid. The income Tax Returns filed by the Company are
not being, to the knowledge of the Company, examined by the Internal Revenue
Service (the "IRS") or other applicable taxing authorities for any period,
except as set out in the Registration Statement. All taxes or estimates thereof
that are due as of December 31, 1995, or are claimed or asserted by any taxing
authority to be due as of such date, have been (a) timely and appropriately paid
so as to avoid penalties for underpayment or (b) accrued for on the balance
sheet as of December 31, 1995, as contained in the Financial Statements. Except
for amounts not yet due and payable, all tax liabilities to which the properties
of the Company may be subject have been paid and discharged. The provisions for
income and other taxes payable reflected in the Financial Statements make
adequate provision for all then accrued and unpaid taxes of the Company. There
are no tax liens on any property of the Company, nor are there any pending or
threatened examinations, actions, suits, investigations, audits, assessments or
tax claims asserted. The Company has not been granted any extensions of
limitation periods applicable to tax claims. Except jurisdictions in which the
Company filed Tax Returns, no claim has been made by a taxing authority that the
Company is or may be subject to taxation by that jurisdiction. All copies of Tax
Returns delivered to Index by the Company are true and correct, and any and all
notices from foreign, federal, state and local taxing authorities, tax
examination reports and statements of deficiencies assessed against or agreed to
by the Company have been made available to Index. The Company is not a party to,
or bound by, any tax indemnity, tax sharing or tax allocation agreement. The
Company is not a member of an "affiliated group," as defined in Section 1504(a)
of the Code and is not the owner of an interest in a partnership, joint venture,
trust, limited liability company or other entity or organization. All positions
taken on federal Tax Returns that could give rise to a penalty for substantial
understatement pursuant to Section 6662(d) of the Code have been disclosed on
such Tax Returns. The Company has not agreed to and is not required to make any
adjustment pursuant to Section 481(a) of the Code (or any predecessor provision)
by reason of any change in any accounting method. The Company has no application
pending with any taxing authority requesting permission for any changes in any
accounting method, and the IRS has not proposed any such adjustment or change in
accounting method. The Company is not subject to any limitation under Section
382 or Section 383 of the Code.
 
     Index shall have sole control over any contest relating to federal, state,
local, or foreign tax assessments or proposed assessments against the Company.
Index shall promptly notify the Company of any audit or examination of the books
and records of the Company undertaken by the tax authorities, any tax
assessments or proposed assessments or any extension of the statute of
limitations applicable to any Tax Returns of the Company relating to any taxable
year or periods ending on or prior to the Closing Date and shall provide the
Company with periodic reports regarding the status of such audit or examination.
The Company shall be entitled to participate in (but not control) any such
contest at its sole cost. Index shall not settle or otherwise compromise any
such contest in a manner which results in liability to the Company under this
Agreement without the written consent of the Company, which consent shall not be
unreasonably withheld.
 
     4.12  Books and Records. The books and records of the Company fairly
reflect the transactions to which the Company is a party or by which its
properties are bound.
 
     4.13  Questionable Payments. The Company nor any employee, agent or
representative of either of them has, directly or indirectly, made any bribes,
kickbacks, illegal payments or illegal political contributions using Company
funds or made any payments from the Company's funds to governmental officials
for improper purposes or made any illegal payments from the Company's funds to
obtain or retain business.

        each of the foregoing has been or may hereafter be amended from time to
        time.

        "hazardous waste" as defined by the RCRA, and regulations promulgated
        thereunder; (B) any "hazardous substance" as defined by CERCLA, and
        regulations promulgated thereunder; (C) any "toxic pollutant" as defined
        in the Federal Water Pollution Prevention and Control Act, as amended,

        and any regulations thereunder; (D) any "hazardous air pollutant" as
        defined in the Air Pollution Prevention and Control Act, as amended, 42
        U.S.C. 7401 et seq. (commonly known as "CAA" for "Clear Air Act") and

        operations of the Company's business.
 
          Notwithstanding the foregoing, if any Environmental Law is amended so
     as to broaden the meaning of any term defined in it, such broader meaning
     shall apply subsequent to the effective date of such amendment. Where a
     defined term in this Agreement derives its meaning from a statutory
     reference, for the purposes of this Agreement any regulatory definition
     promulgated pursuant to the applicable statute shall be deemed to be
     applicable to the extent its definition is broader than the statutory
     reference and any reference or citation to a statute or regulation shall be
     deemed to include any amendments to that statute or regulation and judicial
     and administrative interpretations of it. To the extent that any state laws
     or regulations establish a meaning for a term defined in this Agreement
     through reference to a federal Environmental Law that is broader than the
     meaning specified in such federal Environmental Law, such broader meaning
     set forth in the state Environmental Law shall apply. Any specific
     references to a law shall include any amendments to it promulgated from
     time to time.

        the Company to be in violation of any requirements of Environmental
