      The Shareholders acknowledge and recognize that due to current liquidity
      issues at SEFL and ESS and disputes with LBK (i) the capital structure of

<PAGE>

      Company and/or its subsidiaries, (ii) the terms and conditions of its loan

      third parties to give effect to the restructuring (the "Restructuring").
      For purposes of this Agreement a sale of the assets or stock of SEFL
      and/or ESS are not part of a Restructuring. In recognition that EIC has
      committed to fund a disproportionate share of the cash requirements of
      SEFL and ESS for the remainder of 2003 and in order to facilitate a
      successful Restructuring, which is in the best interest of the Company,
      USE and EIC agree that:

      a) EIC shall assume the lead role in the Restructuring and as such subject
      to Sections 1.3 and 1.9 hereof shall be primarily authorized to and
      responsible for formulating and negotiating with relevant counterparties
      the terms and conditions of such Restructuring, provided that the terms
      and conditions of the Restructuring, proposed by EIC (i) are from the
      standpoint of the Shareholders reasonably prudent under the circumstances,
      and (ii) do not provide any direct or indirect economic benefit to any
      Shareholder or their affiliate other than economic benefits which are
      disclosed to all shareholders and which will be allocated amongst the
      shareholders in accordance with section 1.10 hereof.

      b) EIC shall keep USE fully informed on a contemporaneous basis of all
      developments in the Restructuring and shall provide USE with all
      correspondence and draft and final documentation respecting the
      Restructuring. EIC shall not execute any binding documentation regarding
      the Restructuring without providing USE with complete and accurate copies
      of

                                       6
<PAGE>

      such documentation in advance in order to afford USE a meaningful
      opportunity to review such documentation and discuss such documentation
      with EIC and the Company's advisors.

9.    Section l.4(a)(i) of the Shareholders' Agreement is hereby amended by
      deleting the word "six" and replacing it with the word "five".

10.   Section 1.9(e) of the Shareholder Agreement is amended by deleting the
      unnumbered paragraph and replacing it with the following: then the
      shareholder whose directors voted in favor of the capital call may fund
      additional Priority Shareholder Loans, which shall not exceed the
      Company's, or ESS and its subsidiaries' cash requirements to achieve their
      purposes, as reasonably determined from time to time by the Company based
      on reasonable line item budgets provided to the Shareholders by the
      Company and/or ESS which shall bear an interest rate of STIBOR 90 + 200bp
      per annum compounded quarterly and which shall be paid from the Company's
      cash in accordance with the Distribution Priorities as defined herein. In
      the event of a funding pursuant to the immediately preceding sentence, the
      Company shall issue new Ordinary Shares to the Shareholder supplying the
      funding at a subscription price of 1 Euro per share in accordance with the
      dilution mechanism immediately below (the "Dilution Mechanism").

                                       7
<PAGE>

      Dilution Mechanism

      The Company shall issue 1,893 Ordinary Shares at a subscription price of
      Euro 1 per share for every SEK 1 million of additional Priority
      Shareholder Loans to the Company funded pursuant to this Section 1.9(e).

      The shareholder whose directors voted against the capital call referred to
      above shall irrevocably undertake to vote all of its shares in the Company
      and direct its nominee directors to vote in favor of an resolution
      required to give effect to the provisions contained in this paragraph
      1.9(e). For purposes of this section 1.9 the Company's "purposes" shall
      not include the payment of principal and interest due on Shareholder Loans
      and or Priority Shareholder Loans.

11.   A new subparagraph 1.9(f) is hereby added which states as follows:

      Notwithstanding anything to the contrary herein, EIC shall fund the cash
      requirements of the Company and ESS AB through December 31, 2003 ("2003
      Cash Requirements") under the following terms and conditions:

      i) EIC shall fund all 2003 Cash Requirements up to MSEK 28 as Priority
      Shareholder Loans in accordance with Section 1.9(e) above and in
      consideration of EIC's commitment to make such funding, the Company shall
      issue EIC 52'998 Ordinary Shares at a subscription price of Euro 1 per
      share.

      ii) EIC will consider additional funding of all 2003 Cash Requirements in
      excess of MSEK 28 as a Priority Shareholder Loan in accordance with
      Section 1.9(e) above and upon such funding, the Company shall issue EIC
      additional

                                       8
<PAGE>

      Ordinary Shares of Euro 1 per share in accordance with the Dilution
      Mechanism. For the avoidance of doubt, this does not constitute a
      commitment by EIC.

11.   Section 1.10 is hereby replaced with the following paragraph:

      1.10 Distribution Priorities. The parties shall, subject to applicable law
      disburse the cash of the Company as follows:

                  1.    Payment of services extended by third parties (including
                        amount others audit, tax and accounting services) and
                        taxes.

                  2.    Payment of scheduled interest and principal under the
                        Lantbrukskredit loan.

                  3.    Payment of scheduled interest and principal under any
                        other 3rd party loan.

                  4.    Payment of accrued interest under the Priority
                        Shareholder Loans pro-rata to the respective amounts
                        extended by the shareholders. In case of certain
                        Priority Shareholder Loans have been lent to ESS AB
                        and/or its subsidiaries, the Company shall instruct ESS
                        AB to make such payment.
