Exhibit 10(f)-3 EASTERN To: Barclays Bank Plc, as Agent under the Guarantee and Indemnity referred to below. Copied The Banks and the Participants referred to below and, where applicable, their respective successors and permitted assigns. 11 March 1999 Dear Sirs EASTERN MERCHANT PROPERTIES LIMITED ("EMPL") - -------------------------------------------- RENT FACTORING TRANSACTION (THE "RFI") DATED 28TH OCTOBER 1996 - -------------------------------------------------------------- 1. INTRODUCTION We refer to the Consent Letter dated 17th July 1998 addressed by us to Barclays Bank Plc in relation to the Guarantee and Indemnity dated 28th October 1996 (as amended and restated) relating to the RFT, in which the consent of the Banks (as defined in the Guarantee and Indemnity) and the Participants (as defined in the Deed of Assignment of Rents dated 28th October 1996 relating to the RFT) to certain changes to the terms of the Guarantee and Indemnity was requested. As used in this letter, the expression "Guarantee and Indemnity" means the above Guarantee and Indemnity as amended and restated to date, including by the above Consent Letter. By this letter, we request certain amendments to be made to the Guarantee and Indemnity. 2. BACKGROUND (a) The Consent Letter, as approved by the Banks and the Participants, made certain amendments to the Guarantee and Indemnity, including the insertion of two new financial covenants, a minimum net worth covenant and a gearing limit. For the purposes of both covenants, a new definition - "Adjusted Consolidated Tangible Net Worth" - was introduced and for the purposes of the gearing limit a new definition of "Total Consolidated Net Borrowings" was also introduced. Unfortunately, in this process two errors were made: (i) Paragraph (g) of the definition of Adjusted Consolidated Tangible Net Worth should have given rise to a deduction in respect of "any indebtedness OWED by (i) The Energy Group PLC (now called Energy Holdings (Number 3) Limited), (ii) a TU Company (as defined) or (iii) Texas Utilities Company or any company, partnership or person of which a TU Company is a diret or indirect Subsidiary Undertaking [as defined] or any other direct or indirect Subsidiary Undertaking of any such company, partnership or person, in each case to any member of the Group (as defined)". A typgraphical error was made by using the word "owned" instead of the word "owed" highlighted above. (ii) For the purposes of the gearing limit, the expression "Total Consolidated Net Borrowings" was introduced, defined as the aggregate principal amount of all Borrowings (as already defined) of the Group less Cash (as defined). This new definition thus worked in part off an existing definition (Borrowings) but erred in doing so without qualification. This is because Borrowings as already defined included, as a deemed Borrowing under paragraph (g) of the definition, all premium payable by EMPL to National Power Plc under the National Power headlease. Whilst this was appropriate where the expression Borrowings was used in the cross default clause (Clause 17.1(f)), it was not appropriate in the context of the new gearing covenant, given in particular the nature of the National Power headlease as an operating lease. The inclusion of lease premium as a deemed Borrowing was also inappropriate where that term was used in the context of the original borrowing restrictions (Clauses 4.1(t) and 5(d), which have now been deleted by the above Consent Letter) and the definition of Consolidated Interest, used in the interest cover covenant in Clause 4.1(q), particularly as that covenant already made specific provision for a portion of the rents payable by Eastern Merchant Generation Limited to EMPL under the Lease to be treated as interest. (b) In the past 12 months, Eastern has taken a number of significant steps towards its objective of creating an integrated pan-European energy porfolio. . Purchase of 5% shareholding in Hidroelectrica del Cantabrico (fourth largest electricity company in Spain), and establishing of a joint venture energy trading and risk management company with them to operate in the deregulating Iberian market. . Purchase of the rights to output from two hydro power stations in Norway over a 55 year period, and formation of joint venture energy retail and trading company to operate in the Nord Pool area (Norway, Sweden and Finland). Eastern's JV partner is Lunds Energi, one of the top ten energy retailers in Sweden. . Formation of Compass Energy, a joint venture with Energie Noord West of Holland to retail gas in the deregulating Dutch market. . Establishment of development offices in Madrid, Frankfurt, Stockholm, Prague and Warsaw, to be followed by Paris and Milan. The purchases in Spain and Norway have added some L180 million of additional borrowing to the balance sheet of Eastern Group, although the process to replace a significant portion of this amount with non recourse borrowing is well advanced. At the same time, Eastern's Net Assets have been depleted by the upstreaming of dividends to service the debt introduced by the acquisition of Eastern by Texas Utilities Company. The combination of additional borrowing and reduced cash reserves has pushed Eastern close to the existing 150% gearing ceiling, which will constrain Eastern's ability to make further significant investments until non recourse refinancing creates further headroom. Additional headroom for expansion is included in the revised and restructured facility for Eastern's UK parent TXU Eastern Holdings Limited, that is currently in syndication. The proposed amendment is intended to create a similar effect under this Facility. An increase in the maximum permitted gearing limit to 200%, would enable Eastern to provide the initial finance for new investments, either from cash or short term borrowings, and create time for the arrangement of longer term non recourse refinancing. To address the concern of lenders towards fruther depletion of Net Assets, Eastern offers to increase the minimum Net Worth requirement to L1,000,000,000. 3.
