 THEY DECLARE THAT

  
 Recent developments in the gas market offer opportunities that advise the
execution at this time of the industrial plan of action established by Repsol YPF and La Caixa with respect to Gas Natural pursuant to the Agreement of January 11, 2000 and subsequent renewals. 
  
 To that end, they have reached an Agreement of industrial action that includes: 

 

	 	•	 	Integrated projects that include the upstream phase of gas liquefaction, exploration and production. 

  

	 	•	 	Midstream projects that include the trading, transportation, regasification and wholesale marketing of LNG (more than 0.5 bcm/year). 

  
 The Agreement involves, in the case of integrated projects, the mutual offer by either of the
Parties of an interest in the projects, which, if accepted, will be executed through the corresponding agreements, Repsol YPF leading the exploration and production operations. 
  

 [signed] 

 Translation 
  

 In midstream projects, the Parties shall pool their existing contracts and assets mutually, either through entrusting
the joint management and maximization thereof to a newly formed company, with 50% control, committing to carry out, through such company, the activities of trading, transportation, marketing and regasification, or through any other corporate or
contractual vehicle that will permit joint operation. 
  
 The Agreement guarantees
the supply to cover the commercialization of natural gas in markets where the Parties operate and, in particular, the Iberian, French and Italian markets, with respect to which Gas Natural maintains its responsibility and commitments. 
  
 In consideration of the foregoing, the Parties, mutually acknowledging each other’s
legal capacity, 
  
 AGREE 
  

	I.	INTEGRATED PROJECTS 

  
 FIRST 
 Option to participate in upstream projects 
  

	A.	Integrated or upstream projects are deemed to be those in which Repsol YPF or Gas Natural participate for the purpose of developing the activities of gas exploration, production and
liquefaction. 

  
 To that end, integrated or
upstream projects shall be deemed to be those in which manufactured natural gas is essentially intended to be liquefied in a third party plant or transported by gas pipeline to the European market. 
  

	B.	Repsol YPF and Gas Natural undertake to invite each other to participate in all upstream projects in which they participate or develop. In consideration of this undertaking,

  

	 	•	 	Both Parties shall make their best efforts so that the project structure does not hinder the other Party’s participation. 

  

	 	•	 	All business opportunities that arise shall be analyzed and developed through the teams of both Parties, signing the agreements specific to the applicable sector in each case, in
accordance with Clause SECOND. 

  

	C.	 Unless the circumstances of the project impose a shorter time period, the Party receiving the invitation (hereinafter the “Invited Party”) shall have a
period of two months to analyze the appropriateness of its participation and to communicate its decision. The invitation shall contain the available, specific and reasonable information to obtain a true and complete picture of the project. The
invitation shall be made as soon as the party developing the project first (hereinafter the “Developer”) has a formal invitation from the entity in charge of granting the 

  

 2 

 Translation 
  

	 	 
project to participate in the selection process or has available the initial feasibility studies of a new project, and in any case, must be carried out
before the Developer assumes any commitment or limitation vis-à-vis third parties, so that the preparation of the offer to third parties is made jointly. 

  

	D.	In any event, the Party invited to participate in an upstream project shall assume the required commitments of confidentiality and/or exclusivity. The right of the Parties to
participate in an Upstream Project shall, in all cases, be conditioned on the payment of expenses incurred by the Party invited to participate in the Project. 

  
 SECOND 
 Procedure for Participation
in Upstream Projects 
  

	A.	The participation of the Parties in each Upstream Project shall be documented by agreements corresponding to each project phase, utilizing a “Joint Study and Bidding
Agreement,” an “Assignment Agreement,” an “Area of Mutual Interest Agreement” and/or a “Participating Agreement” in the initial phases and a “Joint Operating Agreement” once the corresponding mining
rights are acquired in the customary terms of the petroleum industry, which shall contain the required specifications. 

  

	B.	The invited Party may acquire a participation in the project in the percentage it decides of the total participation of the Parties to the project in question. The maximum
percentage participation shall be 60% in the case of Repsol YPF and 40% in the case of Gas Natural. Unless agreed by the Parties, the participation percentages of each of the Parties shall be equal in each of the project phases. The Parties may
require that the Midstream Company cooperate in the development of the commercial part related to the negotiation of the LNG purchase agreements with third parties (partners or governments), for which the necessary mechanisms of coordination between
Upstream and Midstream shall be established. 

  

	C.	The Joint Operating Agreement (JOA) shall provide that: 

  

	 	•	 	Repsol YPF shall be the operator of all exploration and production projects, unless another petroleum company participates in the project; in this case, both Parties shall endeavor
to have Repsol YPF also be the operator. Gas Natural’s technical personnel may be included in the exploration and production projects in which it participates. 

  

	 	•	 	For the liquefaction phase, a joint venture company shall be formed that will build and operate the Plant. Repsol YPF shall be responsible for the development and construction of
the Plant. Repsol YPF shall designate the Plant Director and Gas Natural shall designate at least two persons directly below that management level. 

  

 3 

 Translation 
  

	 	•	 	In the exploration and production phases, Repsol YPF shall be the representative vis-à-vis third parties, and a representative of Gas Natural must always be present or duly
informed. Repsol YPF shall act in the best interest of the two Parties. In the liquefaction phase, the company in charge of development and construction of the Plant shall be the representative. 

  

	 	•	 	Certain decisions relevant to the JOA shall be adopted by resolution of both Parties – such as, but not limited to: i) approval of business plans or budgets, ii) assumption of
commitments, sales or acquisitions, or the issuance of guarantees above certain economic thresholds, iii) corporate changes or amendments to resolutions or to the profit contribution or distribution policy – as well as any others that involve
modification, waiver or settlement with respect to the rights of the Parties before third parties or which substantially affect the economic rights of the Parties in the business. Operating decisions shall be adopted by Repsol YPF acting always in
the best interest of both Parties. 

  

	II.	MIDSTREAM PROJECTS 

  
 THIRD 
 Midstream Company 
  

	A.	Repsol YPF and Gas Natural undertake to jointly develop the activities of trading, transportation, regasification and wholesale marketing of LNG or regasified LNG, although the
commitment of the Parties to acquire such gas shall be limited to the provisions of Clause FOURTH.b. To this effect, wholesale marketing shall be deemed to be the sale to customers whose annual consumption exceeds 0.5 bcm/year. Excluded from this
Agreement is the retail marketing worldwide and wholesale marketing of natural gas on the Iberian Peninsula, France and Italy. 

  

	B.	To that end, Repsol YPF and Gas Natural shall form a Spanish corporation (sociedad anónima), whose capital, name and other statutory rules shall be agreed
within the time frame provided in Clause Eighteenth.A (hereinafter “Midstream Company”). Said company shall operate under the trademark agreed by the Parties, in which both shall have a 50% participation and whose purpose shall be that
indicated in the preceding paragraph. 

  

	C.	 A basic objective of the Midstream Company, and with priority over any other, shall be the supply and transportation of LNG to the Spanish market in the most
favorable and timely market conditions. In particular, the Midstream Company shall give preference to the execution of all activities required to deal, in the times, form and conditions of the market, with the supply to Gas Natural of LNG intended
for all markets in which it carries 

  

 4 

 Translation 
  

	 	 
out its retail marketing activities, and especially, with respect to the Spanish market, and to customers with whom Repsol YPF has assumed a delivery
obligation. The Midstream Company undertakes to cooperate in the Integrated Projects for purposes of contributing its commercial experience and market knowledge in the form and manner agreed by the parties for each project.

  
 FOURTH 
 Activity of the Midstream Company 
  

	A.	The Midstream Company assumes the obligation of marketing all of the LNG produced by the Parties, and in return, the Parties assume the obligation to market, through the Midstream
Company, all the LNG they produce. In this type of operation, the Midstream Company shall apply a “net back” pricing system that shifts to the Upstream Project the best available market price, and shall collect a fee for its services.

  

	B.	Sales to the Parties 

  
 The Midstream Company assumes the obligation to cover up to 100% of the LNG needs of Gas Natural and Repsol YPF and in return, Gas Natural and Repsol YPF
undertake to preferentially channel their supply through the Midstream Company. 
  
 Any LNG purchase agreement to supply Gas Natural or Repsol YPF must be specifically approved by the applicable company. 
  
 The Midstream Company shall act as broker for the transactions and shall impose a fee for its management of same. The fee shall be established
periodically so as to ensure equity between contributions and benefits obtained by the shareholders. 
  

	C.	Trading Operations 

  
 On an accessory basis, once the principal purpose of supply to the Parties has been duly met, and with the vital purpose of maximizing the flexibility and
security of such supply, the Midstream Company may also market LNG or regasified LNG, through the purchase or sale to third parties, adopting in its own behalf the appropriate market positions and commitments. 
  

	D.	 To perform its duties, the new company shall manage the current LNG supply and sale agreements executed by the Parties. In these cases, the Midstream Company shall
act as broker of the transactions and impose the fee provided in section B above for handling same. All transactions 

  

 5 

 Translation 
  

	 	 
established by the Midstream Company with respect to these agreements must have the prior approval of the Party holding title to same, to whom the benefits
of the potential maximization of such agreements shall revert. 

  

	E.	The Midstream Company shall utilize the futures and derivatives markets to cover risks and obtain the maximum results from the LNG and natural gas purchase/sale transactions.
Notwithstanding, these transactions shall be subject to the rules and recommendations determined by its Board of Directors. 

  
 FIFTH 
 Fleet Management 
  

	A.	The Parties shall cede to the Midstream Company the management of LNG agreements that they have entered into and making maximum effectiveness of said LNG fleet, making, as
necessary, the timely appraisals of the assets and “time charter” agreements submitted by each Party for its management. 

  

	B.	Services to the Parties 

  
 Both partners shall use the Midstream Company to cover its LNG transportation needs, which it shall manage on the basis of rates at market prices, in
accordance with the publications defined by the parties. The Midstream Company shall also manage the transportation needs that either of the two Parties have acquired. 
  

	C.	Services to Third Parties 

  
 On an accessory basis, once the principal purpose of supply to the Parties has been duly met, and with the vital purpose of maximizing the flexibility and
security of such supply, the Midstream Company may provide services to third parties and will try to maximize its own profits by conveying to the customer a price such that it would be able to have an additional margin as a differential between pool
costs and service price. 
  

	D.	The Parties, although they maintain title to the assets and the “time charter” agreements which each Party submits to be managed, agree that the Midstream Company shall
withhold, as a management fee, the profits from the total maximizations it achieves with joint pool management. 

  

	E.	Both Parties shall consider, in the future, the convenience of having the Midstream Company assume in its own behalf the obtaining of new chartering policies.

  

 6 

 Translation 
  

 SIXTH 
 Regasification Capacity 
  

	A.	To carry out its activity, the Midstream Company must have its own regasification capacity. Such regasification capacity shall come from: 

  

	 	i)	currently available regasification plants, projects that each of the Parties are operating separately and future projects that the partners might undertake. Both Parties undertake
to analyze the joint development of the projects. The regasification capacity or capacity of installations that the Parties have on the Iberian Peninsula, France and Italy are excluded. 

  

	 	ii)	new regasification projects that, upon consideration of the Parties, the company itself may undertake. 

  

	B.	Gas Natural shall be responsible for the development and construction of the regasification plants which the Parties agree to undertake jointly, whether or not through the Midstream
Company, notwithstanding the participation of Repsol YPF’s technical personnel in the different projects. Gas Natural shall appoint the director of the regasification plants and Repsol YPF shall appoint at least two persons directly below that
management level. 

  

	C.	The Parties assume the obligation to cede the current available regasification capacity, by the methods indicated above and in market conditions, to the Midstream Company.

  

	D.	In the event that the Parties consider it more convenient not to develop the projects through the Midstream Company, the Parties undertake to offer each other a participation in the
currently available regasification plants and in any regasification projects they may undertake or could undertake in the future, except on the Iberian Peninsula, France and Italy. The Party holding title to the Plant or the project developer shall
retain a maximum of 50% participation and the groups and companies established to develop the regasification plants shall have bylaws or shareholder resolutions that contemplate the following: 

  

	 	•	 	In dealings with third parties, the Party holding title or developer of the Plant shall be the representative, and a representative of the other Party must also be present. The
representative shall act in the best interest of the two Parties. 

  

 7 

 Translation 
  

	 	•	 	Both Parties shall unanimously adopt certain relevant business decisions – such as, but not limited to: i) approval of business plans or budgets, ii) assumption of commitments,
sales or acquisitions, or the issuance of guarantees above certain economic thresholds, iii) corporate changes or amendments to resolutions or to the profit contribution or distribution policy – as well as any other that involve modification,
waiver or settlement with respect to the rights of the Parties before third parties or which substantially affect the economic rights of the Parties in the business. 

  
 SEVENTH

corporate services that it needs, in market conditions and upon approval by the Board of Directors of the Midstream Company within the general framework of the provision of such services. 

  

	C.	The Midstream Company shall be managed by a Board of Directors comprised of eight persons, four at the proposal of Repsol YPF and four at the proposal of Gas Natural.

assistance, if it considers it necessary, of an outside consultant – so as to ensure equity between contributions and benefits obtained by the shareholders. 

  

	III.	GENERAL PROVISIONS 

  
 EIGHTH 
 Assignment of Interest or Participations 
  

	A.	This Agreement of industrial action is entered into in view of the special technical and economic capacity of the Parties, and the execution of this Agreement involves a special
relationship of collaboration and trust. Therefore, both the participation in the Upstream Projects and the rights and obligations with respect to the Midstream activity, and in particular, the participation in the Midstream Company, may not be
assigned in whole or in part to third parties without the prior and express consent of the other Party. 

  

	B.	Given the scope of the Agreement, it will also not be possible to assign the position of the Parties to any of the companies of the group of which each of the signing Parties is
dominant, undertaking to maintain the Agreement at the level of the leading company in each group. 

  

	C.	In the event of a corporate transaction that affects the independence of one of the Parties, in such manner that it shifts control of one of the dominant companies executing this
Agreement, the other party shall have the right to initiate the liquidation of this Agreement in the manner provided in Clause TENTH.

 Translation 
  

 NINTH 
 Dispute
Resolution 
  

	A.	In Upstream Projects, the most relevant decisions shall be adopted unanimously by the Parties; in the Midstream Company, all decisions, except those of ordinary administration which
correspond to the Chief Executive Officer (Consejero Delegado) of the company, shall be adopted unanimously. 

  

	B.	In the event of shareholder block situations, relevant and substantive discrepancies with respect to management, or if the chief representatives of both Parties do not reach an
agreement pursuant to Clause ELEVENTH, either of the two Parties may demand that collaboration on all projects be terminated and the Midstream Company be dissolved. 

  

	C.	With respect to the Upstream Projects, the Parties shall maintain the existing participations at that moment in the various projects, but shall suspend the duty of offering each
other the acquisition of an interest in new Upstream Projects. 

  
 The Parties, in contemplating the regulations of each project, shall agree on the terms and fulfill the formal obligations to third parties for the exercise of their rights in [such project]. 
  

	D.	With respect to the Midstream Company, it shall be liquidated in accordance with the following criteria: 

  

	 	•	 	the company shall be appraised in consideration of its liquidation. 

  

	 	•	 	50% of the appraisal shall correspond to each Party. 

  

	 	•	 	In the distribution of assets, the guarantee of supply to the retail markets covered by Gas Natural, and in particular, the Spanish market, shall be given first priority. Second
priority shall be given to the supply obligations of Repsol YPF. In such cases, the specific contracts, assets and organization shall be assigned to Gas Natural and to Repsol YPF at the applicable market prices. In remaining cases, an equitable
distribution shall be carried out in market conditions, taking into consideration, as necessary, the initial contribution of assets to the company. 

  

	 	•	 	In the event that there is a difference in value between the two distributed asset packages, an effort will be made to make such difference as minor as possible, once the
distribution criteria in the preceding paragraph have been taken into account. The applicable Party shall pay to the other in cash the difference in value within a period of not more than one month. 

  

 10 

 Translation 
  

	 	•	 	In the event of discrepancy between the Parties with respect to the manner of appraising or distributing the assets, either of them may require that an independent third party
decide, definitively and without appeal, the values or distributions in dispute. In the absence of an agreement with respect to the designation of the independent expert, such expert shall be elected by the casting of lots from among the five major
international auditing firms, excluding those that provide auditing services to any of the Parties. 

  

	E.	If there exist Midstream Projects that the Parties have decided to develop jointly through vehicles other than the Midstream Company, these shall be liquidated, by analogy, in the
manner provided for the liquidation of the Midstream Company. 

  
 TENTH 
 Change of Control 
  

	A.	In the event of a corporate transaction that affects the independence of one of the Parties, in such a way that it shifts control of one of the dominant companies that have executed
this Agreement of industrial action, the Party not affected by the change shall have the right, by the simple fact of officially notifying the other Party to this effect, within a term of two months from the formalization of the change of control,
to either: 

  

	 	1.	Cease collaboration in the Upstream Projects and liquidate the Midstream Company, as well as potential Midstream Projects that the Parties have decided to develop jointly through
vehicles other than the Midstream Company, pursuant to paragraphs C, D and E of Clause NINTH. [or] 

  

	 	2.	Continue with this Agreement of industrial action and in such case, the scope thereof may be extended to all Upstream and Midstream projects of the entire corporate group to which
the company belongs that has taken control or has merged with the Party affected by the change. 

  
 ELEVENTH 
 Rules of Interpretation 
  
 This Agreement of industrial action and its subsequent development and execution must be interpreted in accordance with the rules of good
faith between the parties, equity between the mutual interests and complete equivalency between obligations.

 RISK FACTORS

  
 The World Energy Scenario 
  
 Prices for the sale and purchase of gas are generally benchmarked to the
price of crude oil and derived products. 
  
 Over the last two
years, both the price levels and volatility of crude oil have significantly increased. The average annual listed price of a barrel of Brent oil experienced a 49% increase between May 2004 and May 2005. 
  
 If Gas Natural is not able in the future to pass on such price increases to
consumers, its operating results may be adversely affected. 
  
 Regulation

  
 Gas Natural conducts its business in several countries of
the European Union, Africa and America, in sectors subject to regulation by governments and regulatory authorities. 
  
 Changes in law or regulation in the countries in which Gas Natural operates could therefore adversely affect it. Regulatory decisions concerning, for
example, whether licences or approvals to operate are renewed, whether market developments have been satisfactorily implemented, whether there has been any breach of the terms of a licence or approval, the level of permitted revenues for Gas
Natural’s businesses and proposed business development activities, could have an adverse impact on Gas Natural’s operating results, financial condition and the ability to develop those businesses in the future. 
  
 In the course of conducting its business in a strategic regulated sector, Gas
Natural has entered into agreements with governmental entities. Government entities usually grant long-term permits or licences and establish remuneration systems, so that market participants may recover investments made in their respective
countries. 
  
 Consequently the recovery of investments is
conditional upon the establishment and stability of legal and regulatory frameworks in such countries in the medium and long term. New social, political and economic policies may affect the stability of these frameworks, leading to unforeseen
consequences in the business plans of Gas Natural and may have adverse effects on Gas Natural’s operating results and its financial condition. 
  
 Additionally, the licences and permits required for business development entail the assumption and fulfilment of certain obligations which, if not met,
may result in the interruption of the licences and permits or the execution of future guarantees and deposits, as well as the imposition of surcharges not envisaged in the initial projects. 
  
 In particular, there is significant uncertainty as to the legal and
regulatory framework applicable to transport and distribution of natural gas in Argentina following the significant economic crisis experienced by such country in December 2001. Although negotiations with the Argentine Government in relation to a
new legal and regulatory framework have been on-going for a period of time, no assurances can be given that the new framework will be adopted or that such framework will not adversely affect Gas Natural’s results of operations and financial
condition. 
  
 Latin America 
  
 A significant part of Gas Natural’s activities are conducted in a
number of Latin American countries. The economies of the Latin American countries where Gas Natural operates have experienced significant volatility in recent decades, characterised in some cases by slow or negative growth, declining investment and
significant inflation. This volatility has resulted in fluctuations in the level of business activity and in the relative economic strength of various segments of the economies in which Gas Natural operates. The economies in such countries are, to
varying degrees, also influenced by economic and market conditions in other countries, particularly, negative developments in the economy or securities markets in other emerging markets. Negative conditions in these markets may adversely affect Gas
Natural’s results of operations and financial condition. 
  
 Operating
Risks 
  
 Gas Natural’s various business projects
require the efficient management of various assets under exploitation. 
  

 12 

 External factors may affect the execution, continuity and coordination of asset exploitation. It should
be noted that there are inherent risks in gas exploration and production, supply, distribution and transport and assets related to electricity generation such risks include risks relating to the environment and unforeseen changes in regulatory
frameworks. 
  
 Environmental Risks 
  
 Aspects of Gas Natural’s activities are inherently dangerous, such as
the operation and maintenance of electricity lines and the transmission and distribution of natural gas. Electricity and gas utilities also typically use and generate in their operations hazardous and potentially hazardous products and by-products.
In addition, there may be other aspects of Gas Natural’s operations that are not currently regarded or proved to have adverse effects but could become so, for example, the effects of electric and magnetic fields. Gas Natural is subject to laws
and regulations relating to pollution, the protection of the environment, and how Gas Natural uses and disposes of hazardous substances and waste materials. Gas Natural is also subject to laws and regulations governing health and safety matters,
protecting both the public and its employees. Any breach of these obligations, or even incidents relating to the environment or health and safety that do not amount to a breach, could adversely affect Gas Natural’s operating results, financial
condition and reputation. 
  
 Exchange Rate Volatility 
  
 A significant part of Gas Natural’s revenue from gas activities is
benchmarked to crude oil prices and derived products, which are quoted in U.S. dollars. 
  
 In addition, Gas Natural’s, business in countries such as Argentina, Brazil, Colombia and Mexico, operates in non-Euro currencies. 
  
 Exchange rate volatility of such currencies with respect to the Euro could have adverse effects on Gas Natural’s
financial position and operating results. 
  
 Risks Relating to Withholding

  
 Under Spanish law, income in respect of Notes issued by
Gas Natural Capital Markets, S.A. will be subject to withholding tax in Spain, currently at the rate of 15 per cent., in relation to payments to (a) individual Holders (as defined herein) who are resident in Spain; (b) Holders who
receive payments through a Tax Haven (as defined in Royal Decree 1080/1991, of 5 July, as amended from time to time); and (c) Holders in respect of whom the Guarantor does not receive such information (which may include a tax residence
certificate) concerning such Holder’s identity and tax residence as it may require in order to comply with Law 13/1985 (as defined in the Terms and Conditions of Notes Issued by Gas Natural Capital Markets, S.A.) and any implementing
legislation. Neither Gas Natural Capital Markets, S.A. nor the Guarantor will gross up payments in respect of any such withholding tax in any of the above cases (See “Terms and Conditions of Notes issued by Gas Natural Capital Markets,
S.A.– Taxation”). 
  
 If Notes end up being held by
Spanish corporate entities there is a risk the Spanish tax authorities may determine that the exemption from withholding tax currently applicable to payments of interest to Spanish corporate Noteholders (as described in “Taxation and Disclosure
of Information in Connection with Interest Payments – 2. Legal Entities with Tax Residency in Spain”), does not apply to such Notes. If such determination were made, Gas Natural Capital Markets, S.A. would be required to make a withholding
at the applicable rate, currently 15 per cent., on payments of interest under the Notes and no additional amounts will be payable by Gas Natural Capital Markets, S.A. or the Guarantor in such circumstances under “Terms and Conditions of
Notes issued by Gas Natural Capital Markets, S.A. – Taxation” paragraph (iii). 
  
 Risks Relating to Procedures for Collection of Noteholders’ Details 
  
 It is expected that Gas Natural Capital Markets, S.A., the Guarantor, the Agent, the common depositary for the Notes and the Clearing Systems will follow
certain procedures to facilitate the collection from Noteholders of the information referred to in paragraph (c) of “Risks Relating to Withholding” above. A summary of those procedures is set out in a schedule to the Agency Agreement
and should be read together with “Taxation and Disclosure of Noteholder Information in Connection with Interest Payments”. Such procedures may be revised from time to time in 

  

 13 

 
accordance with applicable Spanish laws and regulations, further clarification from the Spanish tax authorities regarding such laws and regulations and the
operational procedures of the Clearing Systems. While the Notes are represented by one or more global Notes, Noteholders must rely on such procedures in order to receive payments under the Notes free of any withholding, if applicable. Holders must
seek their own advice to ensure that they comply with all applicable procedures and to ensure the correct tax treatment of their Notes. None of Gas Natural Capital Markets, S.A., the Guarantor, the Arranger, the Dealers, the Paying Agents or the
Clearing Systems assume any responsibility therefor. 
  
 Risks Relating to the
Comisario 
  
 Under Spanish law, Gas Natural Capital Markets,
S.A. is required to appoint a commissioner (comisario) (the “Commissioner”) in relation to its Notes. The Commissioner owes certain obligations to the Syndicate of Holders (as described in the Agency Agreement – Schedule 3 Part B).
However, prospective investors should note that the Commissioner will be an individual appointed by Gas Natural Capital Markets, S.A. and that such individual may also be an employee or officer of Gas Natural Capital Markets, S.A. or the Guarantor.

  
 Risks Relating to the Insolvency Law 
  
 Law 22/2003 (Ley Concursal) dated 9 July 2003 (“Law
22/2003” or the “Insolvency Law”), which came into force on 1 September 2004, supersedes all pre-existing Spanish provisions which regulated the bankruptcy, insolvency (including suspension of payments) and any process affecting
creditors’ rights generally, including the ranking of credits in an insolvency. 
  
 Law 22/2003 provides, among other things, that: (i) any claim may become subordinated if it is not included in a company’s accounts or otherwise reported to the insolvency administrators within one month
from the last official publication of the court order declaring the insolvency, (ii) provisions in a contract granting one party the right to terminate on the other’s insolvency may not be enforceable, (iii) interest accrued and
unpaid until the commencement of the insolvency proceedings (concurso) shall become subordinated, and (iv) interest shall cease to accrue from the date of the declaration of insolvency. 
  
 Certain provisions of the Insolvency Law could affect the ranking of Notes
issued by Gas Natural Capital Markets, S.A. or claims relating to such Notes on an insolvency of Gas Natural Capital Markets, S.A. or claims relating to the guarantee of the Notes (whether issued by Gas Natural Finance B.V. or Gas Natural Capital
Markets, S.A.) on an insolvency of the Guarantor. In particular, there is uncertainty surrounding the interpretation of article 87.6 of the Insolvency Law, which may result in claims against Gas Natural Capital Markets, S.A. under the Notes being
re-classified as claims of creditors “specially related” to Gas Natural Capital Markets, S.A as defined in article 92 (5) of the Insolvency Law and become subordinated. However, even if such claims were so re-classified the payment
obligations of the Guarantor under the Guarantee would continue to be classified as ordinary debts in the event of an insolvency of the Guarantor. 
  
 From the entry into force of Law 22/2003, and in accordance with the insolvency procedures regulated therein, creditors whose rights arise from a Spanish
public document, including Noteholders, do not have a preference to enforce their rights and do not rank ahead of other creditors whose rights may arise from a document not so witnessed. 
  
 Risks relating to the tender offer over the shares of Endesa, S.A. 
  
 Potential Changes to the Group 
  
 On 5 September 2005, Gas Natural submitted for its approval by the Spanish Securities Market Commission (Comisión Nacional de Mercado de
Valores) and the relevant regulatory bodies, a tender offer over 100 per cent. of the share capital of Endesa, S.A. (“Endesa”), Spain’s largest electricity company (the “Tender Offer”), conditional upon its
acceptance by shareholders of Endesa, S.A. holding at least 75 per cent. of its share capital and upon the removal of existing limitations in the by-laws of Endesa Consideration for the Endesa shares will be a combination of new Gas Natural
shares and cash. 
  
 As at the date of this Base Prospectus, the
Tender Offer has been approved by the Spanish Energy Commission (Comisión Nacional de la Energía) with certain conditions accepted by Gas Natural and is being reviewed by the Spanish Securities Market Commission (Comisión
Nacional del 

  

 14 

 
Mercado de Valores) and the relevant competition authorities. Should the Tender Offer be approved by such authorities and be consummated, the
business, financial condition, results of operations of Gas Natural and its subsidiaries as a whole (the ‘‘Group’’) following the Tender Offer will substantially differ from the business, financial condition and results of
operations of Gas Natural and its subsidiaries as at the date of and as described in, this Base Prospectus. 
  
 In addition, Gas Natural has entered into a credit and guarantee facility amounting to A7,806 million to fund the cash element of the consideration for
the Tender Offer. As a result of the increase in the Group’s financial indebtedness Moody’s Investors Service Limited (‘‘Moody’s’’) announced that they have placed the Group’s long-term indebtedness on review
for possible downgrade and Standard & Poor’s Rating Services, a Division of the McGraw-Hill Companies (‘‘Standard & Poor’s’’) have placed the Group’s long-term indebtedness on creditwatch
negative, which may result in a lower rating for the long-term indebtedness rating of the Group. 
  
 Risks identified by Gas Natural relating to the Tender Offer 
  

	•	 	Upon completion of the Tender Offer, a significant portion of Gas Natural’s cash flow must be used to service debt obligations, which could have an adverse effect on Gas
Natural’s operating results and financial condition. 

  

	•	 	Regulatory authorities have imposed conditions and may impose additional conditions that could reduce the expected benefits of the combination and may adversely affect the business,
financial condition and results of operations of Gas Natural and its subsidiaries. 

  

	•	 	Gas Natural may be unable to complete anticipated divestitures of certain assets pursuant to the divestiture plan proposed to the Spanish regulatory and competition authorities in
order to secure approval for the Tender Offer. 	 

  

	•	 	Mandatory tender offers in Latin America following the Tender Offer, which may be required to be launched pursuant to local laws in the countries of some of Endesa’s
subsidiaries, may be more costly than expected. 	 

  

	•	 	Consummation of the Tender Offer may result in adverse tax consequences to the combined company resulting from a change of ownership of Endesa. 	 

  

	•	 	The integration of Gas Natural and Endesa may be difficult and expensive and may not result in the benefits that Gas Natural currently expects. 	 

  

	•	 	If Gas Natural is not able to successfully integrate the two companies, the combined company may lose customers. 	 

  

	•	 	Change of control provisions in Endesa’s agreements may be triggered upon Gas Natural’s acquisition of control of Endesa and may lead to adverse consequences, including
the loss of significant contractual rights and benefits, the termination of significant agreements or the need to renegotiate financing agreements. 	 

  

	•	 	Gas Natural has not been given the opportunity to conduct a due diligence review of the non-public records of Endesa nor has it been able to verify the reliability of public
information regarding Endesa. Therefore, Gas Natural may be subject to unknown liabilities of Endesa which may have an adverse effect on the profitability and results of operations of Gas Natural and its subsidiaries. 	 

  

	•	 	If the Tender Offer is successful, but some Endesa securities remain held by the public, the existence of these minority interests in Endesa following the Tender Offer may limit Gas
Natural’s ability to successfully integrate and manage the assets and operations of the combined businesses and, therefore, reduce benefits that it could otherwise achieve. 	 

  
 Risk Relating To The
Notes 
  
 There is no active trading
market for the Notes 
  
 Notes issued under the Programme
will be new securities which may not be widely distributed and for which there is currently no active trading market (unless in the case of any particular tranche, such Tranche is to be consolidated with and form a single series with an outstanding
Tranche of Notes). If the Notes are traded after their initial issuance, they may trade at a discount to their initial offering price, depending upon prevailing interest rates, the market for similar securities, general economic conditions and the
financial condition of the relevant Issuer and the Guarantor. Although applications have been made for the Notes issued under the Programme to be 

  

 15 

 
admitted to listing on the Official List of the FSA and to trading on the Gilt-Edged and Fixed Interest Market of the London Stock Exchange, there is no
assurance that such applications will be accepted, that any particular Tranche of Notes will be so admitted or that an active trading market will develop. Accordingly, there can be no assurance as to the development or liquidity of any trading
market for any particular Tranche of Notes. 
  
 The Notes may be redeemed prior to maturity 
  
 In the case of any particular Tranche of Notes the relevant Final Terms of which specify that the Notes are redeemable at the relevant Issuer’s option in certain other circumstances the relevant Issuer may choose to redeem the Notes at
times when prevailing interest rates may be relatively low. In such circumstances an investor may not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as that of the relevant Tranche of
Notes. 
  
 Because Notes in global form are held by or on behalf of
Euroclear and Clearstream, Luxembourg, investors will have to rely on their procedures for transfer, payment and communication with the relevant Issuer and/or the Guarantor 
  
 Notes issued under the Programme may be represented by one or more global Notes. Such global Notes will be deposited with a
common depositary for Euroclear and Clearstream, Luxembourg. Except in the circumstances described in the relevant global Note, investors will not be entitled to receive definitive Notes. Euroclear and Clearstream, Luxembourg will maintain records
of the beneficial interests in the global Notes. While the Notes are represented by one or more global Notes, investors will be able to trade their beneficial interests only through Euroclear and Clearstream, Luxembourg. 
  
 While the Notes are represented by one or more global Notes the relevant
Issuer and the Guarantor will discharge their payment obligations under the Notes by making payments to the common depositary for Euroclear and Clearstream, Luxembourg for distribution to their account holders. A holder of a beneficial interest in a
global Note must rely on the procedures of Euroclear and Clearstream, Luxembourg to receive payments under the relevant Notes. The Issuers and the Guarantor have no responsibility or liability for the records relating to, or payments made in respect
of, beneficial interests in the global Notes. 
  
 Holders of
beneficial interests in the global Notes will not have a direct right to vote in respect of the relevant Notes. Instead, such holders will be permitted to act only to the extent that they are enabled by Euroclear and Clearstream, Luxembourg to
appoint appropriate proxies. Similarly, holders of beneficial interests in the global Notes will not have a direct right under the global Notes to take enforcement action against the relevant Issuer or the Guarantor in the event of a default under
the relevant Notes but will have to rely upon their rights under the Deed of Covenant. 
  
 Risks Related to Denominations 
  
 Notes admitted
to trading on a regulated market or publicly offered may be issued in a minimum denomination of euro 50,000 or more (or, if the Notes are denominated in a currency other than euro, the equivalent amount in such currency or such higher amount) (the
“Minimum Denomination”). The applicable Final Terms may provide that, for so long as the Notes are represented by a Temporary Global Note or a Permanent Global Note and the relevant clearing system(s) so permit, the Notes may be
tradeable in minimum nominal amounts of the Minimum Denomination and integral multiples of an amount lower than the Minimum Denomination (the “Integral Multiple”) thereafter. However, if definitive Notes are required to be issued in
accordance with the terms of the Temporary Global Note or the Permanent Global Note, they will only be printed and issued in the Minimum Denomination. In these circumstances, a Noteholder holding Notes having a nominal amount which cannot be
represented by a definitive Note in the Minimum Denomination will not be able to receive a definitive Note in respect of such Notes and will not be able to receive interest or principal or be entitled to vote in respect of such Notes. 
  
 Risks related to Adoption of New Accounting Standards in 2005 
  
 The Guarantor must adopt new accounting standards in
2005 that will impact its financial reporting. 
  
 In
2004 the Guarantor prepared its financial statements in accordance with Spanish GAAP. Under current European Union law, listed EU companies have to apply from 1 January 2005 the International Financial Reporting Standards (IFRS) adopted by the
EU in preparing their consolidated financial statements. 
  

 16 

 Applying these standards to the Guarantor’s consolidated financial statements will imply a change in
the presentation of its financial information, since such financial statements prepared under IFRS will reflect classification differences between Spanish GAAP and IFRS, as well as include additional disclosure that is required under IFRS.
Additionally, there will be a change in the valuation of certain assets and liabilities. Regarding the former, at this moment it is not possible to determine the exact impact that this new regulation will have compared to Spanish GAAP, since new
pronouncements from the International Accounting Standards Board (IASB), or pronouncements that are not endorsed by the European Union (EU) prior to the preparation of the Guarantor’s 31 December 2005 consolidated financial statements, may
have an impact on the Guarantor’s financial statements. Therefore, the Guarantor may experience decreases or increases in its shareholders’ equity or its net income or net debt, each as calculated under IFRS, when it prepares its 2005
consolidated financial statements under IFRS. It cannot be assured that any decrease in shareholders’ equity or net income or increase in net debt would not have a material adverse effect on the Guarantor’s results of operations and
financial condition. 
  
 Risks related to the structure of a particular issue
of Notes 
  
 A wide range of Notes may be issued under the
Programme. A number of these Notes may have features which contain particular risks for potential investors. Set out below is a description of the most common such features: 
  
 Notes subject to optional redemption by the relevant Issuer 
  
 An optional redemption feature of Notes is likely to limit their market value. During any period when the relevant Issuer
may elect to redeem Notes, the market value of those Notes generally will not rise substantially above the price at which they can be redeemed. This also may be true prior to any redemption period. 
  
 The relevant Issuer may be expected to redeem Notes when their cost of
borrowing is lower than the interest rate on the Notes. At those times, an investor generally would not be able to reinvest the redemption proceeds at an effective interest rate as high as the interest rate on the Notes being redeemed and may only
be able to do so at a significantly lower rate. Potential investors should consider reinvestment risk in light of other investments available at that time. 
  
 Index Linked Notes and Dual Currency Notes 
  
 The relevant Issuer may issue Notes with principal or interest determined by reference to an index or formula, to changes in the prices of securities or
commodities, to movements in currency exchange rates or other factors (each, a “Relevant Factor”). In addition, the relevant Issuer may issue Notes with principal or interest payable in one or more currencies which may be different from
the currency in which the Notes are denominated. Potential investors should be aware that: 
  

	(i)	the market price of such Notes may be volatile; 

  

	(ii)	they may receive no interest; 

  

	(iii)	payment of principal or interest may occur at a different time or in a different currency than expected; 

  

	(iv)	they may lose all or a substantial portion of their principal; 

  

	(v)	a Relevant Factor may be subject to significant fluctuations that may not correlate with changes in interest rates, currencies or other indices; 

  

	(vi)	if a Relevant Factor is applied to Notes in conjunction with a multiplier greater than one or contains some other leverage factor, the effect of changes in the Relevant Factor on
principal or interest payable likely will be magnified; and 

  

	(vii)	the timing of changes in a Relevant Factor may affect the actual yield to investors, even if the average level is consistent with their expectations. In general, the earlier the
change in the Relevant Factor, the greater the effect on yield. 

  
 Partly-paid Notes 
  
 The Issuers may
issue Notes where the issue price is payable in more than one instalment. Failure to pay any subsequent instalment could result in an investor losing all of their investment. 
  

 17 

 Variable rate Notes with a multiplier or other leverage factor 
  
 Notes with variable interest rates can be volatile investments. If they are
structured to include multipliers or other leverage factors, or caps or floors, or any combination of those features or other similar related features, their market values may be even more volatile than those for securities that do not include those
features. 
  
 Inverse Floating Rate Notes 
  
 Inverse Floating Rate Notes have an interest rate equal to a fixed rate
minus a rate based upon a reference rate such as LIBOR. The market values of those Notes typically are more volatile than market values of other conventional floating rate debt securities based on the same reference rate (and with otherwise
comparable terms). Inverse Floating Rate Notes are more volatile because an increase in the reference rate not only decreases the interest rate of the Notes, but may also reflect an increase in prevailing interest rates, which further adversely
affects the market value of these Notes. 
  
 Fixed/Floating Rate Notes

  
 Fixed/Floating Rate Notes may bear interest at a rate
that the relevant Issuer may elect to convert from a fixed rate to a floating rate, or from a floating rate to a fixed rate. The relevant Issuer’s ability to convert the interest rate will affect the secondary market and the market value of the
Notes since such relevant Issuer may be expected to convert the rate when it is likely to produce a lower overall cost of borrowing. If the relevant Issuer converts from a fixed rate to a floating rate, the spread on the Fixed/Floating Rate Notes
may be less favourable than then prevailing spreads on comparable Floating Rate Notes tied to the same reference rate. In addition, the new floating rate at any time may be lower than the rates on other Notes. If the relevant Issuer convert from a
floating rate to a fixed rate, the fixed rate may be lower than then prevailing rates on its Notes. 
  
 Notes issued at a substantial discount or premium 
  
 The market values of securities issued at a substantial discount or premium from their principal amount tend to fluctuate more in relation to general
changes in interest rates than do prices for conventional interest-bearing securities. Generally, the longer the remaining term of the securities, the greater the price volatility as compared to conventional interest-bearing securities with
comparable maturities. 
  
 EU Savings Directive 
  
 Under EC Council Directive 2003/48/EC on the taxation of savings income,
Member States are required, from 1 July 2005, to provide to the tax authorities of another Member State details of payments of interest (or similar income) paid by a person within its jurisdiction to an individual resident in that other Member
State. However, for a transitional period, Belgium, Luxembourg and Austria are instead required (unless during that period they elect otherwise) to operate a withholding system in relation to such payments (the ending of such transitional period
being dependent upon the conclusion of certain other agreements relating to information exchange with certain other countries). A number of non-EU countries and territories including Switzerland have agreed to adopt similar measures (a withholding
system in the case of Switzerland) with effect from the same date. 
  
 If a payment were to be made or collected through a Member State which has opted for a withholding system and an amount of, or in respect of tax were to be withheld from that payment, neither the Issuers nor any Paying Agent nor any other
person would be obliged to pay additional amounts with respect to any Note as a result of the imposition of such withholding tax. If a withholding tax is imposed on payment made by a Paying Agent, the Issuers will be required to maintain a Paying
Agent in a Member State that will not be obliged to withhold or deduct tax pursuant to the Directive. 
  

 18 

 TERMS AND CONDITIONS OF NOTES 
 ISSUED BY GAS NATURAL FINANCE B.V. 
  
 The following is the text of the terms and conditions which, as supplemented, amended and/or replaced by the relevant Final Terms, will be endorsed on each Note in definitive form issued by Gas Natural Finance B.V.
under the Programme. The terms and conditions applicable to any Note in global form will differ from those terms and conditions which would apply to the Note were it in definitive form to the extent described in the Base Prospectus dated
17 November 2005 relating to the Notes, under “Form of the Notes”. 
  
 Gas Natural Finance B.V. and Gas Natural Capital Markets, S.A. have established a Euro Medium Term Note Programme (the “Programme”) for the issuance of up to Euro 2,000,000,000 in aggregate nominal amount of
Notes (the “Notes”) guaranteed by Gas Natural SDG, S.A. 
  
 Notes issued under the Programme are issued in series (each a “Series”) and each Series may comprise one or more tranches (each a “Tranche”) of Notes. Each Tranche is the subject of final terms (the “Final
Terms”) which supplements these terms and conditions (the “Conditions”). The terms and conditions applicable to any particular Tranche of Notes are these Conditions as supplemented, amended and/or replaced by the relevant Final Terms.
In the event of any inconsistency between these Conditions and the relevant Final Terms, the relevant Final Terms shall prevail. All subsequent references in these Conditions to “Notes” are to the Notes which are the subject of the
relevant Final Terms. The Notes are the subject of an amended and restated agency agreement dated 17 November 2005 (the “Agency Agreement”, which expression shall include any further amendments or supplements thereto) and made between
Gas Natural Finance B.V. (the “Issuer”), Gas Natural Capital Markets, S.A., Gas Natural SDG, S.A. as Guarantor (the “Guarantor”), Citibank, N.A. in its capacities as Agent (the “Agent”, which expression shall include
any successor to Citibank, N.A. in its capacity as such) and the Paying Agents named therein (the “Paying Agents”, which expression shall include the Agent and any substitute or additional Paying Agents appointed in accordance with the
Agency Agreement). The Notes, the Receipts and the Coupons (each as defined below) also have the benefit of a deed of covenant (the “Deed of Covenant”, which expression shall include any amendments or supplements thereto) dated
17 November 2005 executed by the Issuer in relation to the Notes. The Guarantor has, for the benefit of the holders of the Notes from time to time (the “Noteholders”), executed and delivered a Deed of Guarantee (the “Deed of
Guarantee”) dated 17 November 2005 under which it has guaranteed the due and punctual payment of all amounts due by the Issuer under the Notes and the Deed of Covenant as and when the same shall become due and payable. 
  
 Interest bearing definitive Notes (unless otherwise indicated in the
applicable Final Terms) have interest coupons (“Coupons”) and, if indicated in the applicable Final Terms, talons for further Coupons (“Talons”) attached on issue. Any reference herein to Coupons or coupons shall, unless the
context otherwise requires, be deemed to include a reference to Talons or talons. Definitive Notes repayable in instalments have receipts (“Receipts”) for the payment of the instalments of principal (other than the final instalment)
attached on issue. 
  
 Copies of the Deed of Covenant, the Agency
Agreement, the Deed of Guarantee and the Final Terms applicable to the Notes are available for inspection during normal business hours at the specified office of each of the Paying Agents save that any Final Terms relating to an unlisted Note of a
Series will only be available for inspection by a Noteholder holding one or more unlisted Notes of that Series and such Noteholder must produce evidence satisfactory to the relevant Paying Agent as to its identity. All persons from time to time
entitled to the benefit of obligations under any Notes are deemed to have notice of, and are entitled to the benefit of, all the provisions of the Deed of Covenant, the Agency Agreement, the Deed of Guarantee and the applicable Final Terms, which
are binding on them. 
  
 Words and expressions defined in the Deed
of Covenant, the Agency Agreement, the Deed of Guarantee or used in the applicable Final Terms shall have the same meanings where used in these Conditions unless the context otherwise requires or unless otherwise stated and provided that, in the
event of inconsistency, the applicable Final Terms will prevail. 
  
 1. Form,
Denomination and Title 
  
 The Notes are in bearer form and,
in the case of definitive Notes, serially numbered in the Specified Currency and the Specified Denomination(s), provided that in the case of any Notes which are to be admitted to trading on a regulated market within the European Economic Area or

  

 19 

 
offered to the public in a Member State of the European Economic Area in circumstances which require the publication of a prospectus under the Prospectus
Directive, the minimum Specified Denomination shall be euro 50,000 (or its equivalent in any other currency as at the date of issue of those Notes). Notes of one Specified Denomination may not be exchanged for Notes of another Specified
Denomination. 
  
 So long as the Notes are represented by a
Temporary Global Note or a Permanent Global Note and the relevant clearing system(s) so permit, the Notes shall be tradeable in minimum principal amounts of euro 50,000 and integral multiples of euro 1,000 thereafter (or, in each case, its
equivalent in the relevant currency of the Notes on the relevant date of issue). 
  
 Definitive Notes are issued with Coupons attached, unless they are Zero Coupon Notes in which case references to Coupons and Couponholders in these Conditions are not applicable. 
  
 Subject as set out below, title to the Notes, Receipts and Coupons will pass
by delivery. Subject as set out below, the Issuer, the Guarantor, and any Paying Agent may deem and treat (and no such person will be liable for so deeming and treating) the bearer of any Note, Receipt or Coupon as the absolute owner thereof
(whether or not overdue and notwithstanding any notice of ownership or writing thereon or notice of any previous loss or theft thereof) for all purposes but, in the case of any global Note, without prejudice to the provisions set out in the next
succeeding paragraph. 
  
 For so long as any of the Notes is
represented by a global Note, each person who is for the time being shown in the records of Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”) or of Clearstream Banking, société anonyme
(“Clearstream, Luxembourg”) as the holder of a particular nominal amount of Notes (in which regard any certificate or other document issued by Euroclear or Clearstream, Luxembourg as to the nominal amount of Notes standing to the account
of any person shall be conclusive and binding for all purposes save in the case of manifest error) shall be deemed to be the holder of such nominal amount of Notes for all purposes other than with respect to the payment of principal or interest on
the Notes, for which purpose the bearer of the relevant global Note shall be deemed to be the holder of such nominal amount of Notes in accordance with and subject to the terms of the relevant global Note (and the expressions “Noteholder”
and “holder of Notes” and related expressions shall be construed accordingly). Notes which are represented by a global Note will be transferable only in accordance with the rules and procedures for the time being of Euroclear or of
Clearstream, Luxembourg, as the case may be. 
  
 Any reference
herein to Euroclear and/or Clearstream, Luxembourg shall, whenever the context so permits, be deemed to include a reference to any additional or alternative clearance system approved by the Issuer, the Guarantor and the Agent. 
  
 2. Status of the Notes 
  
 The Notes and the relative Receipts and Coupons (if any) are direct, unconditional, unsubordinated and (subject to Condition
4) unsecured obligations of the Issuer ranking pari passu without any preference among themselves and (subject to any applicable statutory exceptions) at least pari passu with all other present and future unsecured and unsubordinated
obligations of the Issuer. 
  
 3. Status of the Deed of Guarantee

  
 Deed of Guarantee 
  
 The payment of principal and interest together with all other sums payable
by the Issuer in respect of the Notes has been unconditionally and irrevocably guaranteed by the Guarantor. The obligations of the Guarantor under the Deed of Guarantee constitute direct, unconditional, unsubordinated and (subject to Condition 4)
unsecured obligations of the Guarantor and (subject to any applicable statutory exceptions) rank pari passu with all other present and future outstanding, unsecured and unsubordinated obligations of the Guarantor. 
  
 In the event of insolvency (concurso) of the Guarantor, under Law 22/2003
(Ley Concursal) dated 9 July 2003 (“Law 22/2003”), claims under the Guarantee relating to Notes (unless they qualify by law as subordinated credits under Article 92 of Law 22/2003) will be ordinary credits (créditos ordinarios)
as defined in Law 22/2003. Ordinary credits rank below credits against the insolvency estate (créditos contra la masa) and credits with a privilege (créditos privilegiados). Ordinary credits rank above subordinated credits and the
rights of shareholders.

 5. Interest 
  

	(a)	Interest on Fixed Rate Notes 

  

	 	(i)	Each Fixed Interest Rate Note shall bear interest on its nominal amount (or, if it is a Partly Paid Note, the amount paid up) from, and including, the Interest Commencement Date
(which shall be the date of issue thereof or such other date as may be specified in the relevant Final Terms) in respect thereof at the rate per annum (expressed as a percentage) equal to the Fixed Rate(s) of Interest specified in the relevant Final
Terms and on the Maturity Date specified in the relevant Final Terms if that date does not fall on a Fixed Interest Date. 

  

	 	(ii)	The first payment of interest will be made on the Fixed Interest Date next following the Interest Commencement Date and, if the period between the Interest Commencement Date and the
first Fixed Interest Date is different from the periods between Fixed Interest Dates, will amount to the Initial Broken Amount specified in the relevant Final Terms. If the Maturity Date is not a Fixed Interest Date, interest from, and including,
the preceding Fixed Interest Date (or from the Interest Commencement Date, as the case may be) to, but excluding, the Maturity Date will amount to the Final Broken Amount specified in the relevant Final Terms. 

  
 If interest is required to be calculated for a period ending other than on a
Fixed Interest Date, such interest shall be calculated by applying the Rate of Interest to each Specified Denomination, multiplying such sum by the applicable Day Count Fraction, and rounding the resultant figure to the nearest sub-unit of the
relevant Specified Currency, half of any such sub-unit being rounded upwards or otherwise in accordance with applicable market convention. 
  
 If a Fixed Coupon Amount or a Broken Amount is specified in the applicable Final Terms, the amount of interest payable on each Fixed Interest Date will
amount to the Fixed Coupon Amount or, if applicable, the Broken Amount so specified. 
  

	 	(iii)	If interest is required to be calculated for a period of other than a full year, such interest shall be calculated: 

  

 22 

	 	(a)	if “Actual/Actual (ICMA)” is specified in the applicable Final Terms: 

  

	 	(i)	in the case of Notes where the number of days in the relevant period from (and including) the most recent Fixed Interest Date, or Interest Payment Date, as the case may be, (or, if
none, the Interest Commencement Date) to (but excluding) the relevant payment date (the “Accrual Period”) is equal to or shorter than the Determination Period during which the Accrual Period ends, the number of days in such Accrual Period
divided by the product of (1) the number of days in such Determination Period and (2) the number of Determination Dates (as specified in the applicable Final Terms) that would occur in one calendar year; or (ii) in the case of Notes
where the Accrual Period is longer than the Determination Period during which the Accrual Period ends, the sum of: 

  

	 	(1)	the number of days in such Accrual Period falling in the Determination Period in which the Accrual Period begins divided by the product of (x) the number of days in such
Determination Period and (y) the number of Determination Dates (as specified in the applicable Final Terms) that would occur in one calendar year; and 

  

	 	(2)	the number of days in such Accrual Period falling in the next Determination Period divided by the product of (x) the number of days in such Determination Period and
(y) the number of Determination Dates that would occur in one calendar year; and 

  

	 	(b)	if “30/360” is specified in the applicable Final Terms, the number of days in the period from and including the most recent Fixed Interest Date, or Interest Payment Date,
as the case may be, (or, if none, the Interest Commencement Date) to but excluding the relevant payment date (such number of days being calculated on the basis of 12 30-day months) divided by 360. 

  
 In these Conditions: 
  
 “Determination Period” means each period from (and including) a
Determination Date to but excluding the next Determination Date (including, where either the Interest Commencement Date or the final Fixed Interest Date is not a Determination Date, the period commencing on the first Determination Date prior to, and
ending on the first Determination Date falling after, such date); and 
  
 “sub-unit” means, with respect to any currency other than euro, the lowest amount of such currency that is available as legal tender in the country of such currency and, with respect to euro, means one cent. 
  

	(b)	Interest on Floating Rate Notes and Index Linked Notes 

  

	 	(i)	Interest Payment Dates 

  
 Each Floating Rate Note and Index Linked Note bears interest on its outstanding nominal amount from (and including) the Interest Commencement Date
specified in the applicable Final Terms and such interest will be payable in arrear on each interest payment date (each an “Interest Payment Date”) which (save as otherwise mentioned in these Conditions or the applicable Final Terms) falls
the number of months or other period specified as the Interest Period in the applicable Final Terms after the preceding Interest Payment Date or, in the case of the first Interest Payment Date, after the Interest Commencement Date. 
  
 If a business day convention is specified in the applicable Final Terms and
if any Interest Payment Date would otherwise fall on a day which is not a Business Day (as defined below), then, if the business day convention specified is: 
  

	 	(1)	 in any case where Interest Periods are specified in accordance with Condition 5(b)(i) above, the Floating Rate Convention, such Interest Payment Date shall be
postponed to the next day which is a Business Day unless it would thereby fall into the next calendar month, in which event (A) such Interest Payment Date shall be brought forward to the immediately preceding Business Day and (B) each
subsequent Interest Payment Date shall be the last Business Day in the month 

  

 23 

	 	 
which falls the number of months or other period specified as the Interest Period in the applicable Final Terms after the preceding applicable Interest
Payment Date occurred; or 

  

	 	(2)	the Following Business Day Convention, such Interest Payment Date shall be postponed to the next day which is a Business Day; or 

  

	 	(3)	the Modified Following Business Day Convention, such Interest Payment Date shall be postponed to the next day which is a Business Day unless it would thereby fall into the next
calendar month, in which event such Interest Payment Date shall be brought forward to the immediately preceding Business Day; or 

  

	 	(4)	the Preceding Business Day Convention, such Interest Payment Date shall be brought forward to the immediately preceding Business Day. 

  
 “Business Day” means (unless otherwise stated in the applicable
Final Terms) a day which is both: 
  

	 	(A)	a day (other than a Saturday or a Sunday) on which commercial banks and foreign exchange markets are open for business in London and Madrid and any Additional Business Centre
specified in the applicable final terms; and 

  

	 	(B)	either (1) in relation to Notes denominated in a Specified Currency other than euro, a day on which commercial banks and foreign exchange markets settle payments in the
principal financial centre of the country of the relevant Specified Currency (if other than London and which if the Specified Currency is Australian dollars shall be Melbourne) or (2) in relation to Notes denominated in euro, a day on which the
TARGET system (as defined in Condition 5(b)(iv)) is operating. 

  

	 	(ii)	Rate of Interest for Floating Rate Notes 

  
 The Rate of Interest payable from time to time in respect of Floating Rate Notes will be determined in the manner specified in the applicable Final Terms.

  

	 	(iii)	ISDA Determination for Floating Rate Notes 

  
 Where ISDA Determination is specified in the applicable Final Terms as the manner in which the Rate of Interest is to be determined, the Rate of Interest
for each Interest Period will be the relevant ISDA Rate plus or minus (as indicated in the applicable Final Terms) the Margin (if any). For the purposes of this sub-paragraph (iii), “ISDA Rate” for an Interest Period means a rate equal to
the Floating Rate that would be determined by the Agent or other person specified in the applicable Final Terms under an interest rate swap transaction if the Agent or that other person were acting as Calculation Agent for that swap transaction
under the terms of an agreement incorporating the ISDA Definitions and under which: 
  

	 	(A)	the Floating Rate Option is as specified in the applicable Final Terms; 

  

	 	(B)	the Designated Maturity is a period equal to that Interest Period; and 

  

	 	(C)	the relevant Reset Date is either (i) if the applicable Floating Rate Option is based on the London inter-bank offered rate (LIBOR) (or, in the case of Notes denominated or
payable in euro, the euro zone interbank market (EURIBOR)) for a currency, the first day of that Interest Period or (ii) in any other case, as specified in the applicable Final Terms. 

  
 For purposes of this sub-paragraph (iii), “Floating Rate”,
“Calculation Agent”, “Floating Rate Option”, “Designated Maturity” and “Reset Date” have the meanings given to those terms in the ISDA Definitions. 
  
 Where this sub-paragraph (iii) applies, in respect of each relevant
Interest Period, the Agent will be deemed to have discharged its obligations under paragraph (g) below in respect of the determination of the Rate of Interest if it has determined the Rate of Interest in respect of such Interest Period in the
manner provided in this sub-paragraph (iii). 
  

 24 

	 	(iv)	Screen Rate Determination for Floating Rate Notes 

  
 Where so specified in the applicable Final Terms, the Rate of Interest for each Interest Period will, subject as provided below, be either: 
  

	 	(A)	the offered quotation (if there is only one quotation on the Relevant Screen Page (as indicated in the applicable Final Terms)), expressed as a percentage rate per annum; or

  

	 	(B)	the arithmetic mean (rounded if necessary to the fourth decimal place, with 0.00005 being rounded upwards) of the offered quotations (expressed as a percentage rate per annum),

  
 for deposits in the Specified Currency for that
Interest Period which appears or appear, as the case may be, on the Relevant Screen Page as at 11.00 a.m. (London time or, where the Reference Rate is EURIBOR, Brussels time) on the Interest Determination Date in question plus or minus (as indicated
in the applicable Final Terms) the Margin (if any), all as determined by the Agent. If five or more such offered quotations are available on the Relevant Screen page, the highest (or, if there is more than one such highest quotation, one only of
such quotations) shall be disregarded by the Agent for the purpose of determining the arithmetic mean (rounded as provided above) of such offered quotations. 
  

If the Relevant Screen Page is not available or if, in the case of (A) above, no such quotation appears or, in the case of (B) above, fewer
than three of such offered quotations appear, in each case as at such time, the Agent shall request the principal London office of each of the Reference Banks (as defined below) or, in the case of the determination of EURIBOR, the principal office
of each of four EURIBOR Reference Banks (as defined below) to provide the Agent with its offered quotation (expressed as a percentage rate per annum) for deposits in the Specified Currency for the relevant Interest Period to leading banks in the
London inter-bank market (or, in the case of the determination of EURIBOR, where the Reference Rate of EURIBOR is used for Notes denominated or payable in euro, the euro zone interbank market) as at 11.00 a.m. (London time or, where the Reference
Rate is EURIBOR, Brussels time) on the Interest Determination Date in question. If two or more of the Reference Banks or, as the case may be, EURIBOR Reference Banks provide the Agent with such offered quotations, the Rate of Interest for such
Interest Period shall be the arithmetic mean (rounded as provided above) of such offered quotations plus or minus (as indicated in the applicable Final Terms) the Margin (if any), all as determined by the Agent. 
  
 If on any Interest Determination Date one only or none of the Reference
Banks or, as the case may be, EURIBOR Reference Banks, provides the Agent with such an offered quotation as provided above, the Rate of Interest for the relevant Interest Period shall be the rate per annum which the Agent determines as being the
arithmetic mean (rounded as provided above) of the rates, as communicated to (and at the request of) the Agent by the Reference Banks or, as the case may be, EURIBOR Reference Banks, or any two or more of them, at which such banks were offered, as
at 11.00 a.m. (London time or, where the Reference Rate is EURIBOR, Brussels time) on the relevant Interest Determination Date, deposits in the Specified Currency for the relevant Interest Period by leading banks in the London inter-bank market (or,
in the case of the determination of EURIBOR, where the Reference Rate of EURIBOR is used for Notes denominated or payable in euro, the euro zone interbank market) plus or minus (as indicated in the applicable Final Terms) the Margin (if any) or, if
fewer than two of the Reference Banks or, as the case may be, EURIBOR Reference Banks, provide the Agent with such offered rates, the offered rate for deposits in the Specified Currency for the relevant Interest Period, or the arithmetic mean
(rounded as provided above) of the offered rates for deposits in the Specified Currency for the relevant Interest Period, at which, on the relevant Interest Determination Date, any one or more banks (which bank or banks is or are suitable for such
purpose) informs the Agent it is quoting to leading banks in the London inter-bank market (or, in the case of the determination of EURIBOR, the euro zone interbank market) (or, as the case may be, the quotations of such bank or banks to the Agent)
plus or minus (as indicated in the applicable Final Terms) the Margin (if any), provided that, if the Rate of Interest cannot be determined in accordance with the foregoing provisions of this sub-paragraph (iv), the Rate of Interest shall be the sum
of 
  

 25 

 the Margin and the offered rate or (as the case may be) the arithmetic mean of the offered notes last
determined in relation to the Notes in respect of the preceding Interest Period. 
  
 In this Condition, the following expressions shall have the following meanings: 
  
 “Reference Banks” means, in the case of (A) above, those banks whose offered rate was used to determine such quotation when such quotation
last appeared on the Relevant Screen Page and, in the case of (B) above, those banks whose offered quotations last appeared on the Relevant Screen Page when no fewer than three such offered quotations appeared; “EURIBOR Reference
Bank” means a major bank operating in the Euro zone interbank market and “EURIBOR Reference Banks” shall be construed accordingly. 
  
 “TARGET system” means the Trans-European Automated Real-time Gross Settlement Express Transfer system. 
  
 If the Reference Rate from time to time in respect of Floating Rate Notes is
specified as being other than the London inter-bank offered rate (or, in the case of Notes denominated or payable in euro, the euro zone interbank market offered rate), the Rate of Interest in respect of such Notes will be determined as provided in
the applicable Final Terms. 
  

	 	(v)	Rate of Interest for Index Linked Notes 

  
 The Rate of Interest in respect of Index Linked Notes for each Interest Period shall be determined in the manner specified hereon otherwise as specified
in the applicable Final Terms and interest will accrue by reference to an Index or Formula as set out in the applicable Final Terms. 
  

	(c)	Dual Currency Notes 

  
 In the case of Dual Currency Notes, if the rate or amount of interest falls to be determined by reference to a Rate of Exchange, the rate or amount of
interest payable shall be determined in the manner specified in the applicable Final Terms. 
  

	(d)	Partly Paid Notes 

  
 In the case of Partly Paid Notes, interest will accrue as aforesaid on the paid-up nominal amount of such Notes and otherwise as specified in the
applicable Final Terms. 
  

	(e)	Accrual of Interest 

  
 Each Note (or in the case of the redemption of part only of a Note, that part only of such Note) will cease to bear interest (if any) from the due date
for its redemption unless, upon due presentation thereof, payment of principal is improperly withheld or refused. In such event, interest will continue to accrue thereon (as well after as before any demand or judgment) at the rate then applicable to
the principal amount of the Notes or such other rate as may be specified in the relevant Final Terms until the date on which, upon (except in the case of any payment where presentation and/or surrender of the relevant Note is not required as a
precondition of payment) due presentation of the relevant Note, the relevant payment is made or, if earlier (except in the case of any payment where presentation and/or surrender of the relevant Note is not required as a precondition of payment),
the seventh day after the date on which the Agent having received the funds required to make such payment, notice is given to the Noteholders in accordance with Condition 15 of that circumstance (except to the extent that there is failure in the
subsequent payment thereof to the relevant Noteholder). 
  

	(f)	Minimum and/or Maximum Rate of Interest 

  
 If the applicable Final Terms specifies a Minimum Rate of Interest for any Interest Period then, in the event that the Rate of Interest in respect of any
such Interest Period determined in accordance with the above provisions is less than such Minimum Rate of Interest, the Rate of Interest for such Interest Period shall be such Minimum Rate of Interest. If the applicable Final Terms specifies a
Maximum Rate of Interest for any Interest Period then, in the event that the Rate of Interest in respect of any such Interest Period determined in accordance with the above provisions is greater than such Maximum Rate of Interest, the Rate of
Interest for such Interest Period shall be such Maximum Rate of Interest. 
  

 26 

	(g)	Determination of Rate of Interest and Calculation of Interest Amount 

  
 The Agent will, at or as soon as practicable after each time at which the Rate of Interest is to be determined, determine
the Rate of Interest and calculate the amount of interest (the “Interest Amount”) payable in respect of any Notes in respect of each Specified Denomination for the relevant Interest Period. Each Interest Amount shall be calculated by
applying the Rate of Interest to each Specified Denomination multiplying such sum by the applicable Day Count Fraction, and rounding the resultant figure to the nearest sub-unit of the relevant Specified Currency, half of any such sub-unit being
rounded upwards or otherwise in accordance with applicable market convention. 
  
 “Day Count Fraction” means, in respect of the calculation of an amount of interest for any Interest Period, and unless any other basis is specified in the relevant Final Terms: 
  

	 	(i)	if “Actual/Actual (ICMA)” is specified in the applicable Final Terms, the relevant calculation in Condition 5(a)(iii)(a) applies, and if “Actual/365” or
“Actual/Actual” is specified in the applicable Final Terms, the actual number of days in the Interest Period divided by 365 (or, if any portion of that Interest Period falls in a leap year, the sum of (A) the actual number of days in
that portion of the Interest Period falling in a leap year divided by 366 and (B) the actual number of days in that portion of the Interest Period falling in a non-leap year divided by 365); 

  

	 	(ii)	if “Actual/365 (Fixed)” is specified in the applicable Final Terms, the actual number of days in the Interest Period divided by 365; 

  

	 	(iii)	if “Actual/365 (sterling)” is specified in the applicable Final Terms, the actual number of days in the Interest Period divided by 365 or, in the case of an Interest
Payment Date falling in a leap year, 366; 

  

	 	(iv)	if “Actual/360” is specified in the applicable Final Terms, the actual number of days in the Interest Period divided by 360; 

  

	 	(v)	if “30/360”, “360/360” or “Bond Basis” is specified in the applicable Final Terms, the number of days in the Interest Period divided by 360 (the number
of days to be calculated on the basis of a year of 360 days with 12 30-day months (unless (a) the last day of the Interest Period is the 31st day of a month but the first day of the Interest Period is a day other than the 30th or 31st day of a
month, in which case the month that includes that last day shall not be considered to be shortened to a 30-day month, or (b) the last day of the Interest Period is the last day of the month of February, in which case the month of February shall
not be considered to be lengthened to a 30-day month)); and 

  

	 	(vi)	if “30E/360” or “Eurobond Basis” is specified in the applicable Final Terms, the number of days in the Interest Period divided by 360 (the number of days to be
calculated on the basis of a year of 360 days with 12 30-day months, without regard to the date of the first day or last day of the Interest Period unless, in the case of an Interest Period ending on the Maturity Date, the Maturity Date is the last
day of the month of February, in which case the month of February shall not be considered to be lengthened to a 30-day month). 

  

	(h)	Notification of Rate of Interest and Interest Amount 

  
 The Agent will cause the Rate of Interest and each Interest Amount for each Interest Period and the relevant Interest Payment Date to be notified to the
Issuer, the Guarantor and to any listing authority, stock exchange and/or quotation system on which the relevant Notes are for the time being listed, traded and/or quoted, and to be published in accordance with Condition 15 as soon as possible after
their determination but in no event later than the fourth Business Day thereafter. Each Interest Amount and Interest Payment Date so notified may subsequently be amended (or appropriate alternative arrangements made by way of adjustment) without
notice in the event of an extension or shortening of the Interest Period. Any such amendment will be promptly notified to each listing authority, stock exchange and/or quotation system on which the relevant Notes are for the time being listed,
traded and/or quoted. 
  

	(i)	Certificates to be final 

  
 All certificates, communications, opinions, determinations, calculations, quotations and decisions given, expressed, made or obtained for the purposes of
the provisions of this paragraph 

  

 27 

 
(b) shall (in the absence of wilful default, bad faith or manifest error) be binding on the Issuer, the Guarantor, the Agent, the Paying Agents and all
Noteholders and (in the absence as aforesaid) no liability to the Issuer, the Guarantor or the Noteholders shall attach to the Agent in connection with the exercise or non-exercise by them of their powers, duties and discretions pursuant to such
provisions. 
  
 6. Redemption and Purchase 
  

	(a)	Redemption at Maturity 

  
 Unless previously redeemed or purchased and cancelled as specified below, each Note will be redeemed by the Issuer, failing which the Guarantor at its
Final Redemption Amount specified in, or determined in the manner specified in, the applicable Final Terms in the relevant Specified Currency on the Maturity Date specified in the applicable Final Terms (in the case of a Note other than a Floating
Rate Note) or on the Interest Payment Date falling in the Redemption Month specified in the applicable Final Terms (in the case of a Floating Rate Note). 
  

	(b)	Redemption for Tax Reasons 

  
 If, in relation to any Series of Notes (i) as a result of any change in the laws or regulations of The Netherlands or the Kingdom of Spain, as
applicable or of any political subdivision thereof or any authority or agency therein or thereof having power to tax or in the interpretation or administration of any such laws or regulations which becomes effective on or after the date of issue of
such Notes or any earlier date specified in the Final Terms the Issuer or the Guarantor, as applicable, would be required to pay additional amounts as provided in Condition 10 and (ii) such circumstances are evidenced by the delivery by the
Issuer or the Guarantor, as applicable, to the Agent of a certificate signed by four managing directors of the Issuer or two directors of the Guarantor, as applicable, stating that the said circumstances prevail and describing the facts leading
thereto and an opinion of independent legal advisers of recognised standing to the effect that such circumstances prevail, the Issuer may, at its option and having given no less than 30 nor more than 60 days’ notice (ending, in the case of
Notes which bear interest at a floating rate, on a day upon which interest is payable) to the Noteholders in accordance with Condition 15 (which notice shall be irrevocable), redeem all (but not some only) of the outstanding Notes comprising the
relevant Series at their early tax redemption amount (the “Early Redemption Amount Tax”) (which shall be their principal amount (or at such other Early Redemption Amount Tax) as may be specified in or determined in accordance with the
relevant Final Terms) less, in the case of any Instalment Note, the aggregate amount of all instalments that shall have become due and payable in respect of such Note prior to the date fixed for redemption under any other Condition (which amount, if
and to the extent not then paid, remains due and payable), together with accrued interest (if any) thereon Provided, however, that no such notice of redemption may be given earlier than 90 days (or, in the case of Notes which bear interest at a

applicable, would be obliged to pay such additional amounts were a payment in respect of the Notes then due. 
  

	(c)	Redemption at the Option of the Issuer 

  
 If a Call Option is specified in the applicable Final Terms, the Issuer may, having (unless otherwise specified in the applicable Final Terms) given not

the Optional Redemption Amount(s) specified in, or determined in the manner specified in, the applicable Final Terms together, if applicable, with interest accrued to (but excluding) the relevant Optional Redemption Date(s). In the event of a

part) such Note on the Optional Redemption Date and at the Optional Redemption Amount specified in, or determined in the manner specified in, the applicable Final Terms together, if applicable, with interest accrued to (but excluding) the relevant
Optional Redemption Date. 
  

	(e)	Early Redemption Amounts 

  
 For the purposes of paragraph (b) above and Condition 10, Zero Coupon Notes will be redeemed at an amount (the “Amortised Face Amount”)
equal to the sum of: 
  

	 	(A)	the Reference Price specified in the applicable Final Terms; and 

  

	 	(B)	the product of the Accrual Yield specified in the applicable Final Terms (compounded annually) being applied to the Reference Price from (and including) the Issue Date to (but
excluding) the date fixed for redemption or (as the case may be) the date upon which such Note becomes due and repayable, 

  
 or such other amount as is provided in the applicable Final Terms. 
  
 Where any calculation of an early redemption amount is to be made for a period which is not a whole number of years, the
calculation in respect of the period of less than a full year shall be made on the basis of a 360-day year consisting of 12 months of 30 days each and, in the case of an incomplete month, the number of days elapsed.

 The Issuer, the Guarantor or any Subsidiary of the Guarantor may at any time purchase Notes (together, in the case of definitive Notes, with all unmatured
Receipts and Coupons appertaining thereto) in any manner and at any price. In the case of a purchase by tender, such tender must be made available to all Noteholders alike. The Issuer, the Guarantor or any Subsidiary of the Guarantor will be
entitled to hold and deal with Notes so purchased as the Issuer, the Guarantor or the relevant Subsidiary of the Guarantor thinks fit. 
  

	(h)	Cancellation 

  
 All Notes which are redeemed in full will forthwith be cancelled and Notes which are purchased by or on behalf of the Issuer, the Guarantor or any
Subsidiary of the Guarantor may, at the election of the Issuer, be cancelled (together in each case with all unmatured Receipts and Coupons attached thereto or delivered therewith). Notes purchased by or on behalf of the Issuer, the Guarantor or any
Subsidiary of the Guarantor may not be reissued or resold other than to the Issuer, the Guarantor or any Subsidiary of the Guarantor. 
  

	(i)	Late Payment on Zero Coupon Notes 

  
 If the amount payable in respect of any Zero Coupon Note upon redemption of such Zero Coupon Note pursuant to paragraph (a), (b), (d) or
(e) above or upon its becoming due and repayable as provided in Condition 11 is improperly withheld or refused, the amount due and repayable in respect of such Zero Coupon Note shall be the amount calculated as provided in paragraph
(e) above as though the references therein to the date fixed for redemption or the date upon which the Zero Coupon Note becomes due and repayable were replaced by references to the date which is the earlier of: 
  

	 	(1)	the date on which all amounts due in respect of the Zero Coupon Note have been paid; and

 Subject as provided below: 
  

	 	(i)	payments in a currency other than euro will be made by transfer to an account in the relevant Specified Currency maintained by the payee with, or by a cheque in such Specified
Currency drawn on, a bank in the principal financial centre of the country of such Specified Currency; and 

  

	 	(ii)	payments in euro will be made by transfer to a euro account (or any other account to which euro may be credited or transferred) maintained by the payee with a bank in the principal
financial centre of any Participating Member State of the European Communities. 

  
 Payments will be subject in all cases to any fiscal or other laws and regulations applicable thereto in the place of payment, but without prejudice to the provisions of Condition 10. 
  
 In these Conditions: 
  
 “Euro zone” means the zone comprising the Member States of the
European Union which adopt or have adopted the euro as their lawful currency in accordance with the Treaty; 
  
 “Participating Member State” means a Member State of the European Communities which adopt or have adopted the euro as its lawful currency in
accordance with the Treaty; and 
  
 “Treaty” means the
Treaty establishing the European Communities, as amended. 
  

	(b)	Presentation of Notes, Receipts, Coupons and Talons 

  
 Payments of principal in respect of definitive Notes will (subject as provided below) be made in the manner provided in paragraph (a) above against
surrender of definitive Notes and payments of interest in respect of definitive Notes will (subject as provided below) be made as aforesaid against surrender of Coupons, in each case at the specified office of any Paying Agent outside the United
States. 
  
 Payments of instalments (if any) of principal, other
than the final instalment, will (subject as provided below) be made against presentation and surrender of the relevant Receipt. Each Receipt must be presented for payment of the relevant instalment together with the definitive Note to which it
appertains. Receipts presented without the definitive Notes to which they appertain do not constitute valid obligations of the Issuer. Upon the date on which any definitive Note becomes due and repayable, unmatured Receipts (if any) appertaining
thereto (whether or not attached) shall become void and no payment shall be made in respect thereof. 
  
 Fixed Rate Notes in definitive form (other than Dual Currency Notes or Index Linked Notes) should be presented for payment together with all unmatured
Coupons appertaining thereto (which expression shall for this purpose include Coupons falling to be issued on exchange of matured Talons) failing which the amount of any missing unmatured Coupon (or, in the case of payment not being made in full,
the same proportion of the amount of such missing unmatured Coupon as the sum so paid bears to the sum due) will be deducted from the sum due for payment. Each amount of principal so deducted will be paid in the manner mentioned above against
surrender of the relative missing Coupon at any time before the expiry of ten years after the Relevant Date (as defined in Condition 10) in respect of such principal (whether or not such Coupon would otherwise have become void under Condition 14)
or, if later, five years from the date on which such Coupon would otherwise have become due. Upon any Fixed Rate Note becoming due and repayable prior to its Maturity Date, all unmatured Talons (if any) appertaining thereto will become void and no
further Coupons will be issued in respect thereof. 
  
 Upon the
date on which any Floating Rate Note, Dual Currency Note or Indexed Note in definitive form becomes due and repayable, unmatured Coupons and Talons (if any) relating thereto (whether or not attached) shall become void and no payment or, as the case
may be, exchange for further Coupons shall be made in respect thereof. 
  
 If the due date for redemption of any definitive Note is not a Fixed Interest Date or an Interest Payment Date, interest (if any) accrued in respect of such Note from (and including) the preceding Fixed Interest Date or Interest Payment
Date or, as the case may be, the Interest Commencement Date shall be payable only against surrender of the relevant definitive Note. 
  

 30 

 Payments of principal and interest (if any) in respect of Notes represented by any global Note will
(subject as provided below) be made in the manner specified above in relation to definitive Notes and otherwise in the manner specified in the relevant global Note against presentation or surrender, as the case may be, of such global Note at the
specified office of the Agent. A record of each payment made against presentation or surrender of such global Note, distinguishing between any payment of principal and any payment of interest, will be made on such global Note by the Agent and such
record shall be prima facie evidence that the payment in question has been made. 
  
 The holder of the relevant global Note shall be the only person entitled to receive payments in respect of Notes represented by such global Note and the Issuer or, as the case may be, the Guarantor will be discharged
by payment to, or to the order of, the holder of such global Note in respect of each amount so paid. Each of the persons shown in the records of Euroclear or Clearstream, Luxembourg as the holder of a particular nominal amount of Notes must look
solely to Euroclear or Clearstream, Luxembourg, as the case may be, for his share of each payment so made by the Issuer or, as the case may be, the Guarantor to, or to the order of, the holder of the relevant global Note. No person other than the
holder of the relevant global Note shall have any claim against the Issuer or, as the case may be, the Guarantor in respect of any payments due on that global Note. 
  
 Payments of interest in respect of the Notes will be made at the specified office of a Paying Agent in the United States
(which expression, as used herein, means the United States of America (including the States and the District of Columbia, its territories, its possessions and other areas subject to its jurisdiction)) if: 
  

	 	(i)	the Issuer has appointed Paying Agents with specified offices outside the United States with the reasonable expectation that such Paying Agents would be able to make payment at such
specified offices outside the United States of the full amount of interest on the Notes in the manner provided above when due; 

  

	 	(ii)	payment of the full amount of such interest at such specified offices outside the United States is illegal or effectively precluded by exchange controls or other similar
restrictions; and 

  

	 	(iii)	such payment is then permitted under United States law without involving, in the opinion of the Issuer and the Guarantor, adverse tax consequences to the Issuer.

  

	(c)	Redenomination 

  
 Where Redenomination is specified in the applicable Final Terms as being applicable, the Issuer may, without the consent of the Noteholders or the holders
of related Receipts or Coupons on giving at least 30 days’ prior notice to the Noteholders in accordance with Condition 15, elect that, with effect from the Redenomination Date specified in the notice, the Notes shall be redenominated in euro.
The election will have effect as follows: 
  

	 	(i)	each Specified Denomination will be deemed to be denominated in such amount of euro as is equivalent to its denomination in the Specified Currency at the Established Rate, subject

	 	(ii)	after the Redenomination Date, all payments in respect of the Notes, the Receipts and the Coupons will be made solely in euro, including payments of interest in respect of periods
before the Redenomination Date, as though references in the Notes to the Specified Currency were to euro; and 

  

	 	(iii)	such changes shall be made to these Conditions as the Issuer may decide and as may be specified in the notice, to conform them to conventions then applicable to instruments
denominated in euro or to enable the Notes to be consolidated with one or more issues of other notes, whether or not originally denominated in the Specified Currency or euro. 

  

	(d)	Exchangeability 

  
 Where Exchangeability is specified in the applicable Final Terms as being applicable, the Issuer may without the consent of the Noteholders or the holders
of related Receipts or Coupons, on 

  

 31 

 
giving at least 30 days’ prior notice to the Noteholders in accordance with Condition 15, elect that, with effect from the Redenomination Date or such
later date for payment of interest under the Notes as it may specify in the notice, the Notes shall be exchangeable for Notes expressed to be denominated in euro in accordance with such arrangements as the Issuer may decide and as may be specified
in the notice, including arrangements under which Receipts and Coupons unmatured at the date so specified become void. 
  
 In this Condition, the following expressions have the following meanings: 
  
 “Established Rate” means the rate for conversion of the Specified Currency (including compliance with rules
relating to roundings in accordance with applicable European Community regulations) into euro established by the Council of the European Union pursuant to Article 109(4) of the Treaty;

until the next following Payment Day in the relevant place and shall not be entitled to further interest or other payment in respect of such delay. For these purposes, unless otherwise specified in the applicable Final Terms, “Payment Day”
means any day which is both: 
  

	 	(i)	a day (other than a Saturday or a Sunday) on which banks are open for business in

	 	(ii)	either (1) in relation to Notes denominated in a Specified Currency other than euro, a day on which commercial banks and foreign exchange markets settle payments in the
principal financial centre of the relevant Specified Currency (if other than London and which if the Specified Currency is Australian dollars shall be Melbourne) or (2) in relation to notes denominated in euro, a day on which the TARGET System
(as defined in Condition 5(b)(iv) is operating). 

  

	(f)	Interpretation of Principal and Interest 

  
 Any reference in these Conditions to principal in respect of the Notes shall be deemed to include, as applicable: 
  

	 	(i)	any additional amounts which may be payable with respect to principal under Condition 10; 

  

	 	(ii)	the Final Redemption Amount of the Notes; 

  

	 	(iii)	the Early Redemption Amount of the Notes; 

  

	 	(iv)	the Optional Redemption Amount(s) (if any) of the Notes; 

  

	 	(v)	in relation to Notes redeemable in instalments, the Instalment Amounts; and 

  

	 	(vi)	any premium and any other amounts which may be payable under or in respect of the Notes. 

  
 Any reference in these Conditions to interest in respect of the Notes shall be deemed to include, as applicable, any

 The Issuer and the Guarantor are entitled to vary or terminate the appointment of any Paying Agent and/or appoint additional or other Paying Agents and/or
approve any change in the specified office through which any Paying agent acts, provided that: 
  

	 	(i)	so long as the Notes are admitted to listing, trading and/or quotation by any listing authority, stock exchange and/or quotation system, there will at all times be a Paying Agent

 In addition, the Issuer and the Guarantor shall forthwith appoint a Paying Agent having a specified office in New York City in the circumstances described
in the final paragraph of Condition 7(b). Any variation, termination, appointment or change shall only take effect (other than in the case of insolvency, when it shall be of immediate effect) after not less than 30 nor more than 45 days’ prior
notice thereof shall have been given to the Noteholders in accordance with Condition 15 provided that no such variation, termination, appointment or change shall take effect (except in the case of insolvency) within 15 days before or after any Fixed
Interest Date or Interest Payment Date, as the case may be. 
  
 9. Exchange of
Talons 
  
 On and after the Fixed Interest Date or the
Interest Payment Date, as appropriate, on which the final Coupon comprised in any Coupon sheet matures, the Talon (if any) forming part of such Coupon sheet may be surrendered at the specified office of the Agent or any Paying Agent in exchange for
a further Coupon sheet including (if such further Coupon sheet does not include Coupons to (and including) the final date for the payment of interest due in respect of the Notes to which it appertains) a further Talon, subject to the provisions of
Condition 13. Each Talon shall, for the purposes of these Conditions, be deemed to mature on the Fixed Interest Date or the Interest Payment Date (as the case may be) on which the final Coupon comprised in the relative Coupon sheet matures.

  
 10. Taxation 
  
 All amounts payable (whether in respect of principal, redemption amount,
interest or otherwise) in respect of the Notes will be made free and clear of and without withholding or deduction for or on account of any present or future taxes, duties, assessments or governmental charges of whatever nature imposed or levied by
or on behalf of The Netherlands or the Kingdom of Spain, as the case may be, or any political subdivision thereof or any authority or agency therein or thereof having power to tax, unless the withholding or deduction of such taxes, duties,
assessments or governmental charges is required by law. In that event, the Issuer, failing which the Guarantor, will pay such additional amounts as may be necessary in order that the net amounts receivable by any Noteholder after such withholding or
deduction shall equal the respective amounts which would have been receivable by such Noteholder in the absence of such withholding or deduction; except that no such additional amounts shall be payable in relation to any payment in respect of any
Notes or Coupon: 
  

	 	(i)	to, or to a third party on behalf of, a Noteholder who is liable to such taxes, duties, assessments or governmental charges in respect of such Notes by reason of his having some
connection with The Netherlands or, as applicable, the Kingdom of Spain other than the mere holding of such Notes or Coupon; or 

  

	 	(ii)	presented for payment more than thirty days after the Relevant Date, except to the extent that the relevant Noteholder would have been entitled to such additional amounts on
presenting the same for payment on the expiry of such period of thirty days; or

	 	(v)	presented for payment by or on behalf of a Noteholder who would have been able to avoid such withholding or deduction by presenting the relevant Note or Coupon to another Paying
Agent in a member state of the European Union.

respectively shall be read and construed as references to The Netherlands or the Kingdom of Spain, as the case may be, and/or to such other jurisdiction. 
  
 Any reference in these Conditions to principal, redemption amount and/or interest in respect of the Notes shall be deemed also to refer to any additional
amounts which may be payable under this Condition 10.

appropriate, for communication by them to the Noteholders. Any such notice shall be deemed to have been given to the Noteholders on the seventh day after the day on which the said notice was given to Euroclear and/or Clearstream, Luxembourg, as
appropriate. 
  
 Notices to be given by any Noteholder shall be in
writing and given by lodging the same, together with the relative Note or Notes, with the Agent. Whilst any of the Notes are represented by a global Note, such notice may be given by any Noteholder to the Agent via Euroclear and/or Clearstream,
Luxembourg, as the case may be, in such manner as the Agent and Euroclear and/or Clearstream, Luxembourg, as the case may be, may approve for this purpose. 
  
 16. Further Issues 
  
 The Issuer shall be at liberty from time to time without the consent of the Noteholders to create and issue further notes ranking pari passu in all
respects (or in all respects save for the first payment of interest thereon) with the outstanding Notes and so that the same shall be consolidated and form a single series with the outstanding Notes.

substitute under this Condition 17); 

  

	 	(iii)	if the Substituted Debtor is resident for tax purposes in a territory (the “New Residence”) other than that in which the Issuer prior to such substitution was resident for
tax purposes (the “Former Residence”) the Documents contain an undertaking and/or such other provisions as may be necessary to ensure that each Noteholder of the Relevant Notes has the benefit of an undertaking in terms corresponding to

 18. Governing Law; Submission to Jurisdiction 

 
 The Agency Agreement, the Deed of Covenant, the Deed of Guarantee and the
Notes are governed by, and shall be construed in accordance with, English law. The Issuer and the Guarantor irrevocably agree for the benefit of the Noteholders that the courts of England shall have jurisdiction to hear and determine any suit,
action or proceedings, and to settle any disputes (together “Proceedings”), which may arise out of or in connection with the Agency Agreement, the Deed of Covenant, the Deed of Guarantee and the Notes and, for such purpose, irrevocably
submit to the jurisdiction of such courts. 
  
 The Issuer and the
Guarantor irrevocably and unconditionally waive and agree not to raise any objection which any of them may have now or subsequently to the laying of the venue of any Proceedings in the courts of England and any claim that any Proceedings have been
brought in an inconvenient forum and further irrevocably and unconditionally agree that a judgment in any Proceedings brought in the courts of England shall be conclusive and binding upon each of them and may be enforced in the courts of any other
jurisdiction. Nothing in this Condition shall limit any right to take Proceedings against the Issuer and/or the Guarantor in any other court of competent jurisdiction, nor shall the taking of Proceedings in one or more jurisdictions preclude the
taking of Proceedings in any other jurisdiction, whether concurrently or not. 
  
 The Issuer and the Guarantor irrevocably and unconditionally appoint Law Debenture Corporate Services Limited at Fifth Floor, 100 Wood Street, London EC2V 7EX as agent for service of process in England in respect of
any Proceedings and undertake that in the event of it ceasing so to act the Issuer and the Guarantor will forthwith appoint a further person as their agent for that purpose and notify the name and address of such person to the Agent and agree that,
failing such appointment within fifteen days, any Noteholder shall be entitled to appoint such a person by written notice addressed to the Issuer and the Guarantor and delivered to the Issuer and the Guarantor or to the specified office of the

 TERMS AND CONDITIONS OF NOTES 
 ISSUED BY GAS NATURAL CAPITAL MARKETS, S.A. 
  
 The following is the text of the terms and conditions which, as supplemented, amended and/or replaced by the relevant Final Terms, will be endorsed on
each Note in definitive form issued by Gas Natural Capital Markets, S.A. under the Programme. The terms and conditions applicable to any Note in global form will differ from those terms and conditions which would apply to the Note were it in
definitive form to the extent described in the Base Prospectus dated 17 November 2005 relating to the Notes, under “Form of the Notes”. 
  
 Gas Natural Finance B.V. and Gas Natural Capital Markets, S.A. have established a Euro Medium Term Note Programme (the “Programme”) for the
issuance of up to Euro 2,000,000,000 in aggregate nominal amount of Notes (the “Notes”) guaranteed by Gas Natural SDG, S.A. 
  
 Notes issued under the Programme are issued in series (each a “Series”) and each Series may comprise one or more tranches (each a
“Tranche”) of Notes. Each Tranche is the subject of final terms (the “Final Terms”) which supplements these terms and conditions (the “Conditions”). The terms and conditions applicable to any particular Tranche of Notes
are these Conditions as supplemented, amended and/or replaced by the relevant Final Terms. In the event of any inconsistency between these Conditions and the relevant Final Terms, the relevant Final Terms shall prevail. All subsequent references in
these Conditions to “Notes” are to the Notes which are the subject of the relevant Final Terms. The Notes are the subject of an amended and restated agency agreement dated 17 November 2005 (the “Agency Agreement”, which
expression shall include any further amendments or supplements thereto) and made between Gas Natural Finance B.V., Gas Natural Capital Markets, S.A. (the “Issuer”), Gas Natural SDG, S.A. as Guarantor (the “Guarantor”), Citibank,
N.A. in its capacities as Agent (the “Agent”, which expression shall include any successor to Citibank, N.A. in its capacity as such) and the Paying Agents named therein (the “Paying Agents”, which expression shall include the
Agent and any substitute or additional Paying Agents appointed in accordance with the Agency Agreement). The Notes, the Receipts and the Coupons (each as defined below) also have the benefit of a deed of covenant (the “Deed of Covenant”,
which expression shall include any amendments or supplements thereto) dated 17 November 2005 executed by the Issuer in relation to the Notes. The Guarantor has, for the benefit of the holders of the Notes from time to time (the
“Noteholders”), executed and delivered a Deed of Guarantee (the “Deed of Guarantee”) dated 17 November 2005 under which it has guaranteed the due and punctual payment of all amounts due by the Issuer under the Notes and the
Deed of Covenant as and when the same shall become due and payable. If so required by Spanish law, the Issuer will execute an escritura pública (“Public Deed”) before a Spanish Notary Public in relation to the Notes and will
register such Public Deed with the Mercantile Registry of Barcelona on or prior to the issue date of the Notes. The Public Deed contains, among other information, the terms and conditions of the Notes. 
  
 Interest bearing definitive Notes (unless otherwise indicated in the
applicable Final Terms) have interest coupons (“Coupons”) and, if indicated in the applicable Final Terms, talons for further Coupons (“Talons”) attached on issue. Any reference herein to Coupons or coupons shall, unless the
context otherwise requires, be deemed to include a reference to Talons or talons. Definitive Notes repayable in instalments have receipts (“Receipts”) for the payment of the instalments of principal (other than the final instalment)
attached on issue. 
  
 Copies of the Deed of Covenant, the Agency
Agreement, the Deed of Guarantee and the Final Terms applicable to the Notes are available for inspection during normal business hours at the specified office of each of the Paying Agents. All persons from time to time entitled to the benefit of
obligations under any Notes are deemed to have notice of, and are entitled to the benefit of, all the provisions of the Deed of Covenant, the Agency Agreement, the Deed of Guarantee and the applicable Final Terms, which are binding on them.

  
 Words and expressions defined in the Deed of Covenant, the
Agency Agreement, the Deed of Guarantee or used in the applicable Final Terms shall have the same meanings where used in these Conditions unless the context otherwise requires or unless otherwise stated and provided that, in the event of
inconsistency, the applicable Final Terms will prevail. 
  
 1. Form,
Denomination and Title 
  
 The Notes are in bearer form and,
in the case of definitive Notes, serially numbered in the Specified Currency and the Specified Denomination(s), provided that in the case of any Notes which 

  

 39 

 
are to be admitted to trading on a regulated market within the European Economic Area or offered to the public in a Member State of the European Economic
Area in circumstances which require the publication of a prospectus under the Prospectus Directive, the minimum Specified Denomination shall be euro 50,000 (or its equivalent in any other currency as at the date of issue of those Notes). Notes of
one Specified Denomination may not be exchanged for Notes of another Specified Denomination. 
  
 So long as the Notes are represented by a Temporary Global Note or a Permanent Global Note and the relevant clearing system(s) so permit, the Notes shall be tradeable in minimum principal amounts of euro 50,000 and
integral multiples of euro 1,000 thereafter (or, in each case, its equivalent in the relevant currency of the Notes on the relevant date of issue). 
  
 Definitive Notes are issued with Coupons attached, unless they are Zero Coupon Notes in which case references to Coupons and Couponholders in these
Conditions are not applicable. 
  
 Subject as set out below, title
to the Notes, Receipts and Coupons will pass by delivery. Subject as set out below, the Issuer, the Guarantor, and any Paying Agent may deem and treat (and no such person will be liable for so deeming and treating) the bearer of any Note, Receipt or
Coupon as the absolute owner thereof (whether or not overdue and notwithstanding any notice of ownership or writing thereon or notice of any previous loss or theft thereof) for all purposes but, in the case of any global Note, without prejudice to
the provisions set out in the next succeeding paragraph. 
  
 For
so long as any of the Notes is represented by a global Note, each person who is for the time being shown in the records of Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”) or of Clearstream Banking,
société anonyme (“Clearstream, Luxembourg”) as the holder of a particular nominal amount of Notes (in which regard any certificate or other document issued by Euroclear or Clearstream, Luxembourg as to the nominal
amount of Notes standing to the account of any person shall be conclusive and binding for all purposes save in the case of manifest error) shall be deemed to be the holder of such nominal amount of Notes for all purposes other than with respect to
the payment of principal or interest on the Notes, for which purpose the bearer of the relevant global Note shall be deemed to be the holder of such nominal amount of Notes in accordance with and subject to the terms of the relevant global Note (and
the expressions “Noteholder” and “holder of Notes” and related expressions shall be construed accordingly). Notes which are represented by a global Note will be transferable only in accordance with the rules and procedures for
the time being of Euroclear or of Clearstream, Luxembourg, as the case may be. 
  
 Any reference herein to Euroclear and/or Clearstream, Luxembourg shall, whenever the context so permits, be deemed to include a reference to any additional or alternative clearance system approved by the Issuer, the
Guarantor and the Agent. 
  
 2. Status of the Notes 
  
 The Notes and the relative Receipts and Coupons (if any) are direct,
unconditional, unsubordinated and (subject to Condition 4) unsecured obligations of the Issuer ranking pari passu without any preference among themselves and (subject to any applicable statutory exceptions) at least pari passu with all other
present and future unsecured and unsubordinated obligations of the Issuer. 
  
 Holders of Notes acknowledge that all Notes issued or to be issued by the Issuer under the Programme shall rank pari passu among themselves regardless of their respective issue date. By purchasing the Notes,
holders of the Notes expressly waive any priority that may apply to them pursuant to Article 288 of the Ley de Sociedades Anónimas (Spanish Companies Law) and, therefore, acknowledge that their rights under the Notes shall rank pari
passu with rights of holders of other Notes issued by the Issuer under the Programme. 
  
 In the event of insolvency (concurso) of the Issuer, under Law 22/2003 (Ley Concursal) dated 9 July 2003 (“Law 22/2003”), claims relating to Notes (unless they qualify by law as subordinated credits
under Article 92 of Law 22/2003) will be ordinary credits (créditos ordinarios) as defined in Law 22/2003. Ordinary credits rank below credits against the insolvency estate (créditos contra la masa) and credits with a privilege
(créditos privilegiados). Ordinary credits rank above subordinated credits and the rights of shareholders. 
  

 40 

 3. Status of the Deed of Guarantee 
  
 Deed of Guarantee 
  
 The payment of principal and interest together with all other sums payable by the Issuer in respect of the Notes has been unconditionally and irrevocably
guaranteed by the Guarantor. The obligations of the Guarantor under the Deed of Guarantee constitute direct, unconditional, unsubordinated and (subject to Condition 4) unsecured obligations of the Guarantor and (subject to any applicable statutory
exceptions) rank pari passu with all other present and future outstanding, unsecured and unsubordinated obligations of the Guarantor. 
  
 In the event of insolvency (concurso) of the Guarantor, under Law 22/2003, claims under the Guarantee relating to Notes (unless they qualify by law as
subordinated credits under Article 92 of Law 22/2003) will be ordinary credits (créditos ordinarios) as defined in Law 22/2003. Ordinary credits rank below credits against the insolvency estate (créditos contra la masa) and credits
with a privilege (créditos privilegiados). Ordinary credits rank above subordinated credits and the rights of shareholders.

 41 

	 	(B)	any Security Interest that does not fall within sub-paragraph (A) above and that secures Relevant Indebtedness which, when aggregated with Relevant Indebtedness secured by all

	 	(ii)	in relation to the Guarantor or any of its Subsidiaries:

 5. Interest 
  

	(a)	Interest on Fixed Rate Notes 

  

	 	(i)	Each Fixed Interest Rate Note shall bear interest on its nominal amount (or, if it is a Partly Paid Note, the amount paid up) from, and including, the Interest Commencement Date
(which shall be the date of issue thereof or such other date as may be specified in the relevant Final Terms) in respect thereof at the rate per annum (expressed as a percentage) equal to the Fixed Rate(s) of Interest specified in the relevant Final
Terms and on the Maturity Date specified in the relevant Final Terms if that date does not fall on a Fixed Interest Date. 

  

	 	(ii)	 The first payment of interest will be made on the Fixed Interest Date next following the Interest Commencement Date and, if the period between the Interest
Commencement Date and the first Fixed Interest Date is different from the periods between Fixed Interest Dates, will amount to the Initial Broken Amount specified in the relevant Final Terms. If the Maturity Date is not a Fixed Interest Date,
interest from, and including, the 

  

 42 

	 	 
preceding Fixed Interest Date (or from the Interest Commencement Date, as the case may be) to, but excluding, the Maturity Date will amount to the Final
Broken Amount specified in the relevant Final Terms. 

  
 If interest is required to be calculated for a period ending other than on a Fixed Interest Date, such interest shall be calculated by applying the Rate of Interest to each Specified Denomination, multiplying such sum by the applicable Day
Count Fraction, and rounding the resultant figure to the nearest sub-unit of the relevant Specified Currency, half of any such sub-unit being rounded upwards or otherwise in accordance with applicable market convention. 
  
 If a Fixed Coupon Amount or a Broken Amount is specified in the applicable
Final Terms, the amount of interest payable on each Fixed Interest Date will amount to the Fixed Coupon Amount or, if applicable, the Broken Amount so specified. 
  

	 	(iii)	If interest is required to be calculated for a period of other than a full year, such interest shall be calculated: 

  

	 	(a)	if “Actual/Actual (ICMA)” is specified in the applicable Final Terms: 

  

	 	(i)	in the case of Notes where the number of days in the relevant period from (and including) the most recent Fixed Interest Date, or interest Payment Date, as the case may be, (or, if
none, the Interest Commencement Date) to (but excluding) the relevant payment date (the “Accrual Period”) is equal to or shorter than the Determination Period during which the Accrual Period ends, the number of days in such Accrual Period
divided by the product of (1) the number of days in such Determination Period and (2) the number of Determination Dates (as specified in the applicable Final Terms) that would occur in one calendar year; or (ii) in the case of Notes
where the Accrual Period is longer than the Determination Period during which the Accrual Period ends, the sum of: 

  

	 	(1)	the number of days in such Accrual Period falling in the Determination Period in which the Accrual Period begins divided by the product of (x) the number of days in such
Determination Period and (y) the number of Determination Dates (as specified in the applicable Final Terms) that would occur in one calendar year; and 

  

	 	(2)	the number of days in such Accrual Period falling in the next Determination Period divided by the product of (x) the number of days in such Determination Period and
(y) the number of Determination Dates that would occur in one calendar year; and 

  

	 	(b)	if “30/360” is specified in the applicable Final Terms, the number of days in the period from and including the most recent Fixed Interest Date, or interest Payment Date,
as the case may be, (or, if none, the Interest Commencement Date) to but excluding the relevant payment date (such number of days being calculated on the basis of 12 30-day months) divided by 360. 

  
 In these Conditions: 
  
 “Determination Period” means each period from (and including) a
Determination Date to but excluding the next Determination Date (including, where either the Interest Commencement Date or the final Fixed Interest Date is not a Determination Date, the period commencing on the first Determination Date prior to, and
ending on the first Determination Date falling after, such date); and “sub-unit” means, with respect to any currency other than euro, the lowest amount of such currency that is available as legal tender in the country of such currency and,
with respect to euro, means one cent. 
  

	(b)	Interest on Floating Rate Notes and Index Linked Notes 

  

	 	(i)	Interest Payment Dates 

  
 Each Floating Rate Note and Index Linked Note bears interest on its outstanding nominal amount from (and including) the Interest Commencement Date
specified in the applicable Final Terms and such interest will be payable in arrear on each interest 

  

 43 

 
payment date (each an “Interest Payment Date”) which (save as otherwise mentioned in these Conditions or the applicable Final Terms) falls the
number of months or other period specified as the Interest Period in the applicable Final Terms after the preceding Interest Payment Date or, in the case of the first Interest Payment Date, after the Interest Commencement Date. 
  
 If a business day convention is specified in the applicable Final Terms and
if any Interest Payment Date would otherwise fall on a day which is not a Business Day (as defined below), then, if the business day convention specified is: 
  

	 	(1)	in any case where Interest Periods are specified in accordance with Condition 5(b)(i) above, the Floating Rate Convention, such Interest Payment Date shall be postponed to the next
day which is a Business Day unless it would thereby fall into the next calendar month, in which event (A) such Interest Payment Date shall be brought forward to the immediately preceding Business Day and (B) each subsequent Interest
Payment Date shall be the last Business Day in the month which falls the number of months or other period specified as the Interest Period in the applicable Final Terms after the preceding applicable Interest Payment Date occurred; or

  

	 	(2)	the Following Business Day Convention, such Interest Payment Date shall be postponed to the next day which is a Business Day; or 

  

	 	(3)	the Modified Following Business Day Convention, such Interest Payment Date shall be postponed to the next day which is a Business Day unless it would thereby fall into the next
calendar month, in which event such Interest Payment Date shall be brought forward to the immediately preceding Business Day; or 

  

	 	(4)	the Preceding Business Day Convention, such Interest Payment Date shall be brought forward to the immediately preceding Business Day. 

  
 “Business Day” means (unless otherwise stated in the applicable
Final Terms) a day which is both: 
  

	 	(A)	a day (other than a Saturday or a Sunday) on which commercial banks and foreign exchange markets are open for business in London and Madrid and any Additional Business Centre
specified in the applicable Final Terms; and 

  

	 	(B)	either (1) in relation to Notes denominated in a Specified Currency other than euro, a day on which commercial banks and foreign exchange markets settle payments in the
principal financial centre of the country of the relevant Specified Currency (if other than London and which if the Specified Currency is Australian dollars shall be Melbourne) or (2) in relation to Notes denominated in euro, a day on which the
TARGET system (as defined in Condition 5(b)(iv)) is operating. 

  

	 	(ii)	Rate of Interest for Floating Rate Notes 

  
 The Rate of Interest payable from time to time in respect of Floating Rate Notes will be determined in the manner specified in the applicable Final Terms.

  

	 	(iii)	ISDA Determination for Floating Rate Notes 

  
 Where ISDA Determination is specified in the applicable Final Terms as the manner in which the Rate of Interest is to be determined, the Rate of Interest
for each Interest Period will be the relevant ISDA Rate plus or minus (as indicated in the applicable Final Terms) the Margin (if any). For the purposes of this sub-paragraph (iii), “ISDA Rate” for an Interest Period means a rate equal to
the Floating Rate that would be determined by the Agent or other person specified in the applicable Final Terms under an interest rate swap transaction if the Agent or that other person were acting as Calculation Agent for that swap transaction
under the terms of an agreement incorporating the ISDA Definitions and under which: 
  

	 	(A)	the Floating Rate Option is as specified in the applicable Final Terms; 

  

	 	(B)	the Designated Maturity is a period equal to that Interest Period; and 

  

 44 

	 	(C)	the relevant Reset Date is either (i) if the applicable Floating Rate Option is based on the London inter-bank offered rate (LIBOR) (or, in the case of Notes denominated or
payable in euro, the euro zone interbank market (EURIBOR)) for a currency, the first day of that Interest Period or (ii) in any other case, as specified in the applicable Final Terms. 

  
 For purposes of this sub-paragraph (iii), “Floating Rate”,
“Calculation Agent”, “Floating Rate Option”, “Designated Maturity” and “Reset Date” have the meanings given to those terms in the ISDA Definitions. 
  
 Where this sub-paragraph (iii) applies, in respect of each relevant
Interest Period, the Agent will be deemed to have discharged its obligations under paragraph (g) below in respect of the determination of the Rate of Interest if it has determined the Rate of Interest in respect of such Interest Period in the
manner provided in this sub-paragraph (iii). 
  

	 	(iv)	Screen Rate Determination for Floating Rate Notes 

  
 Where so specified in the applicable Final Terms, the Rate of Interest for each Interest Period will, subject as provided below, be either: 
  

	 	(A)	the offered quotation (if there is only one quotation on the Relevant Screen Page (as indicated in the applicable Final Terms)), expressed as a percentage rate per annum; or

  

	 	(B)	the arithmetic mean (rounded if necessary to the fourth decimal place, with 0.00005 being rounded upwards) of the offered quotations (expressed as a percentage rate per annum),

  
 for deposits in the Specified Currency for that
Interest Period which appears or appear, as the case may be, on the Relevant Screen Page as at 11.00 a.m. (London time or, where the Reference Rate is EURIBOR, Brussels time) on the Interest Determination Date in question plus or minus (as indicated
in the applicable Final Terms) the Margin (if any), all as determined by the Agent. If five or more such offered quotations are available on the Relevant Screen page, the highest (or, if there is more than one such highest quotation, one only of
such quotations) shall be disregarded by the Agent for the purpose of determining the arithmetic mean (rounded as provided above) of such offered quotations. 
  

If the Relevant Screen Page is not available or if, in the case of (A) above, no such quotation appears or, in the case of (B) above, fewer
than three of such offered quotations appear, in each case as at such time, the Agent shall request the principal London office of each of the Reference Banks (as defined below) or, in the case of the determination of EURIBOR, the principal office
of each of four EURIBOR Reference Banks (as defined below) to provide the Agent with its offered quotation (expressed as a percentage rate per annum) for deposits in the Specified Currency for the relevant Interest Period to leading banks in the
London inter-bank market (or, in the case of the determination of EURIBOR, where the Reference Rate of EURIBOR is used for Notes denominated or payable in euro, the euro zone interbank market) as at 11.00 a.m. (London time or, where the Reference
Rate is EURIBOR, Brussels time) on the Interest Determination Date in question. If two or more of the Reference Banks or, as the case may be, EURIBOR Reference Banks provide the Agent with such offered quotations, the Rate of Interest for such
Interest Period shall be the arithmetic mean (rounded as provided above) of such offered quotations plus or minus (as indicated in the applicable Final Terms) the Margin (if any), all as determined by the Agent. 
  
 If on any Interest Determination Date one only or none of the Reference
Banks or, as the case may be, EURIBOR Reference Banks, provides the Agent with such an offered quotation as provided above, the Rate of Interest for the relevant Interest Period shall be the rate per annum which the Agent determines as being the
arithmetic mean (rounded as provided above) of the rates, as communicated to (and at the request of) the Agent by the Reference Banks or, as the case may be, EURIBOR Reference Banks, or any two or more of them, at which such banks were offered, as
at 11.00 a.m. (London time or, where the Reference Rate is EURIBOR, Brussels time) on the relevant Interest Determination Date, deposits in the Specified Currency for the relevant Interest Period by 

  

 45 

 
leading banks in the London inter-bank market (or, in the case of the determination of EURIBOR, where the Reference Rate of EURIBOR is used for Notes
denominated on payable in euro, the euro zone interbank market) plus or minus (as indicated in the applicable Final Terms) the Margin (if any) or, if fewer than two of the Reference Banks or, as the case may be, EURIBOR Reference Banks, provide the
Agent with such offered rates, the offered rate for deposits in the Specified Currency for the relevant Interest Period, or the arithmetic mean (rounded as provided above) of the offered rates for deposits in the Specified Currency for the relevant
Interest Period, at which, on the relevant Interest Determination Date, any one or more banks (which bank or banks is or are suitable for such purpose) informs the Agent it is quoting to leading banks in the London inter-bank market (or, in the case
of the determination of EURIBOR, the euro zone interbank market) (or, as the case may be, the quotations of such bank or banks to the Agent) plus or minus (as indicated in the applicable Final Terms) the Margin (if any), provided that, if the Rate
of Interest cannot be determined in accordance with the foregoing provisions of this sub-paragraph (iv), the Rate of Interest shall be the sum of the Margin and the offered rate or (as the case may be) the arithmetic mean of the offered Notes last
determined in relation to the Notes in respect of the preceding Interest Period.). 
  
 In this Condition, the following expressions shall have the following meanings: 
  
 “Reference Banks” means, in the case of (A) above, those banks whose offered rate was used to determine such quotation when such quotation
last appeared on the Relevant Screen Page and, in the case of (B) above, those banks whose offered quotations last appeared on the Relevant Screen Page when no fewer than three such offered quotations appeared; 
  
 “EURIBOR Reference Bank” means a major bank operating in the Euro
zone interbank market and “EURIBOR Reference Banks” shall be construed accordingly. 
  
 “TARGET system” means the Trans-European Automated Real-time Gross Settlement Express Transfer system. 
  

	 	(v)	Rate of Interest for Index Linked Notes 

  
 The Rate of Interest in respect of Index Linked Notes for each Interest Period shall be determined in the manner specified hereon otherwise as specified
in the applicable Final Terms and interest will accrue by reference to an Index or Formula as set out in the applicable Final Terms. 
  

	(c)	Dual Currency Notes 

  
 In the case of Dual Currency Notes, if the rate or amount of interest falls to be determined by reference to a Rate of Exchange, the rate or amount of
interest payable shall be determined in the manner specified in the applicable Final Terms. 
  

	(d)	Partly Paid Notes 

  
 In the case of Partly Paid Notes, interest will accrue as aforesaid on the paid-up nominal amount of such Notes and otherwise as specified in the
applicable Final Terms. 
  

	(e)	Accrual of Interest 

  
 Each Note (or in the case of the redemption of part only of a Note, that part only of such Note) will cease to bear interest (if any) from the due date
for its redemption unless, upon due presentation thereof, payment of principal is improperly withheld or refused. In such event, interest will continue to accrue thereon (as well after as before any demand or judgment) at the rate then applicable to
the principal amount of the Notes or such other rate as may be specified in the relevant Final Terms until the date on which, upon (except in the case of any payment where presentation and/or surrender of the relevant Note is not required as a
precondition of payment) due presentation of the relevant Note, the relevant payment is made or, if earlier (except in the case of any payment where presentation and/or surrender of the relevant Note is not required as a precondition of payment),
the seventh day after the date on which the Agent having received the funds required to make such payment, notice is given to the Noteholders in accordance with Condition 15 of that circumstance (except to the extent that there is failure in the
subsequent payment thereof to the relevant Noteholder). 
  

 46 

 If the Reference Rate from time to time in respect of Floating Rate Notes is specified as being other
than the London inter-bank offered rate (or, in the case of Notes denominated or payable in euro, the euro zone interbank market offered rate), the Rate of Interest in respect of such Notes will be determined as provided in the applicable Final
Terms. 
  

	(f)	Minimum and/or Maximum Rate of Interest 

  
 If the applicable Final Terms specifies a minimum Rate of Interest for any Interest Period then, in the event that the Rate of Interest in respect of any
such Interest Period determined in accordance with the above provisions is less than such Minimum Rate of Interest, the Rate of Interest for such Interest Period shall be such Minimum Rate of Interest. If the applicable Final Terms specifies a
Maximum Rate of Interest for any Interest Period then, in the event that the Rate of Interest in respect of any such Interest Period determined in accordance with the above provisions is greater than such Maximum Rate of Interest, the Rate of
Interest for such Interest Period shall be such Maximum Rate of Interest. 
  

	(g)	Determination of Rate of Interest and Calculation of Interest Amount 

  
 The Agent will, at or as soon as practicable after each time at which the Rate of Interest is to be determined, determine
the Rate of Interest and calculate the amount of interest (the “Interest Amount”) payable in respect of any Notes in respect of each Specified Denomination for the relevant Interest Period. Each Interest Amount shall be calculated by
applying the Rate of Interest to each Specified Denomination multiplying such sum by the applicable Day Count Fraction, and rounding the resultant figure to the nearest sub-unit of the relevant Specified Currency, half of any such sub-unit being
rounded upwards or otherwise in accordance with applicable market convention. 
  
 “Day Count Fraction” means, in respect of the calculation of an amount of interest for any Interest Period, and unless any other basis is specified in the relevant Final Terms: 
  

	 	(i)	if “Actual/Actual (ICMA)” is specified in the applicable Final Terms, the relevant calculation in Condition 5(a)(iii)(a) applies, and if “Actual/365” or
“Actual/Actual” is specified in the applicable Final Terms, the actual number of days in the Interest Period divided by 365 (or, if any portion of that Interest Period falls in a leap year, the sum of (A) the actual number of days in
that portion of the Interest Period falling in a leap year divided by 366 and (B) the actual number of days in that portion of the Interest Period falling in a non-leap year divided by 365); 

  

	 	(ii)	if “Actual/365 (Fixed)” is specified in the applicable Final Terms, the actual number of days in the Interest Period divided by 365; 

  

	 	(iii)	if “Actual/365 (sterling)” is specified in the applicable Final Terms, the actual number of days in the Interest Period divided by 365 or, in the case of an Interest
Payment Date falling in a leap year, 366; 

  

	 	(iv)	if “Actual/360” is specified in the applicable Final Terms, the actual number of days in the Interest Period divided by 360; 

  

	 	(v)	if “30/360”, “360/360” or “Bond Basis” is specified in the applicable Final Terms, the number of days in the Interest Period divided by 360 (the number
of days to be calculated on the basis of a year of 360 days with 12 30-day months (unless (a) the last day of the Interest Period is the 31st day of a month but the first day of the Interest Period is a day other than the 30th or 31st day of a
month, in which case the month that includes that last day shall not be considered to be shortened to a 30-day month, or (b) the last day of the Interest Period is the last day of the month of February, in which case the month of February shall
not be considered to be lengthened to a 30-day month)); and 

  

	 	(vi)	if “30E/360” or “Eurobond Basis” is specified in the applicable Final Terms, the number of days in the Interest Period divided by 360 (the number of days to be
calculated on the basis of a year of 360 days with 12 30-day months, without regard to the date of the first day or last day of the Interest Period unless, in the case of an Interest Period ending on the Maturity Date, the Maturity Date is the last
day of the month of February, in which case the month of February shall not be considered to be lengthened to a 30-day month). 

  

 47 

	(h)	Notification of Rate of Interest and Interest Amount 

  
 The Agent will cause the Rate of Interest and each Interest Amount for each Interest Period and the relevant Interest Payment Date to be notified to the
Issuer, the Guarantor and to any listing authority, stock exchange and/or quotation system on which the relevant Floating Rate Notes are for the time being listed, traded and/or quoted, and to be published in accordance with Condition 15 as soon as
possible after their determination but in no event later than the fourth Business Day thereafter. Each Interest Amount and Interest Payment Date so notified may subsequently be amended (or appropriate alternative arrangements made by way of
adjustment) without notice in the event of an extension or shortening of the Interest Period. Any such amendment will be promptly notified to each listing authority, stock exchange and/or quotation system on which the relevant Floating Rate Notes
are for the time being listed, traded and/or quoted. 
  

	(i)	Certificates to be final 

  
 All certificates, communications, opinions, determinations, calculations, quotations and decisions given, expressed, made or obtained for the purposes of
the provisions of this paragraph (b) shall (in the absence of wilful default, bad faith or manifest error) be binding on the Issuer, the Guarantor, the Agent, the Paying Agents and all Noteholders and (in the absence as aforesaid) no liability
to the Issuer, the Guarantor or the Noteholders shall attach to the Agent in connection with the exercise or non-exercise by them of their powers, duties and discretions pursuant to such provisions. 
  
 6. Redemption and Purchase 
  

	(a)	Redemption at Maturity 

  
 Unless previously redeemed or purchased and cancelled as specified below, each Note will be redeemed by the Issuer, failing which the Guarantor at its
Final Redemption Amount specified in, or determined in the manner specified in, the applicable Final Terms in the relevant Specified Currency on the Maturity Date specified in the applicable Final Terms (in the case of a Note other than a Floating
Rate Note) or on the Interest Payment Date falling in the Redemption Month specified in the applicable Final Terms (in the case of a Floating Rate Note). 
  

	(b)	Redemption for Tax Reasons 

  
 If, in relation to any Series of Notes (i) as a result of any change in the laws or regulations of the Kingdom of Spain or of any political
subdivision thereof or any authority or agency therein or thereof having power to tax or in the interpretation or administration of any such laws or regulations which becomes effective on or after the date of issue of such Notes or any earlier date
specified in the Final Terms the Issuer or the Guarantor, as applicable, would be required to pay additional amounts as provided in Condition 10 and (ii) such circumstances are evidenced by the delivery by the Issuer or the Guarantor, as
applicable, to the Agent of a certificate signed by a director of the Issuer or two directors of the Guarantor, as applicable, stating that the said circumstances prevail and describing the facts leading thereto and an opinion of independent legal
advisers of recognised standing to the effect that such circumstances prevail, the Issuer may, at its option and having given no less than 30 nor more than 60 days’ notice (ending, in the case of Notes which bear interest at a floating rate, on
a day upon which interest is payable) to the Noteholders in accordance with Condition 15 (which notice shall be irrevocable), redeem all (but not some only) of the outstanding Notes comprising the relevant Series at their early tax redemption amount
(the “Early Redemption Amount Tax”) (which shall be their principal amount (or at such other Early Redemption Amount Tax) as may be specified in or determined in accordance with the relevant Final Terms) less, in the case of any Instalment
Note, the aggregate amount of all instalments that shall have become due and payable in respect of such Note prior to the date fixed for redemption under any other Condition (which amount, if and to the extent not then paid, remains due and
payable), together with accrued interest (if any) thereon Provided, however, that no such notice of redemption may be given earlier than 90 days (or, in the case of Notes which bear interest at a floating rate a number of days which is equal to the
aggregate of the number of days falling within the then current interest period applicable to the Notes plus 60 days) prior to the earliest date on which the Issuer or the Guarantor, as applicable, would be obliged to pay such additional amounts
were a payment in respect of the Notes then due. 
  

 48 

	(c)	Redemption at the Option of the Issuer 

  
 If a Call Option specified in the applicable Final Terms, the Issuer may, having (unless otherwise specified in the applicable Final Terms) given not more
than 60 nor less than 30 days’ notice to the Agent and, in accordance with Condition 15, the Noteholders (which notice shall be irrevocable), redeem all or some only of the Notes then outstanding on the Optional Redemption Date(s) and at the
Optional Redemption Amount(s) specified in, or determined in the manner specified in, the applicable Final Terms together, if applicable, with interest accrued to (but excluding) the relevant Optional Redemption Date(s). In the event of a redemption
of some only of the Notes, such redemption must be of a nominal amount being the Minimum Redemption Amount or a Higher Redemption Amount, both as indicated in the applicable Final Terms, and shall be carried out in accordance with applicable Spanish
law requirements. In the case of a partial redemption of definitive Notes, the Notes to be redeemed will be selected individually by lot, subject to compliance with applicable law (including applicable Spanish law requirements) and the rules of each
listing authority, stock exchange and/or quotation system (if any) by which the Notes have then been admitted to listing, trading and/or quotation, not more than 60 days prior to the date fixed for redemption and a list of the Notes called for
redemption will be published in accordance with Condition 15 not less than 30 days prior to such date. In the case of a partial redemption of Notes which are represented by a global Note, the relevant Notes will be selected in accordance with the
rules of Euroclear and/or Clearstream, Luxembourg. 
  

	(d)	Redemption at the Option of the Noteholders 

  
 If a Put Option specified in the applicable Final Terms, upon any Noteholder giving to the Issuer and the Guarantor in accordance with Condition 15 not
more than 60 nor less than 30 days’ notice (which notice shall be irrevocable), the Issuer will, upon the expiry of such notice, redeem subject to, and in accordance with, the terms specified in the applicable Final Terms in whole (but not in
part) such Note on the Optional Redemption Date and at the Optional Redemption Amount specified in, or determined in the manner specified in, the applicable Final Terms together, if applicable, with interest accrued to (but excluding) the relevant
Optional Redemption Date. 
  

	(e)	Early Redemption Amounts 

  
 For the purposes of paragraph (b) above and Condition 10, Zero Coupon Notes will be redeemed at an amount (the “Amortised Face Amount”)
equal to the sum of: 
  

	 	(A)	the Reference Price specified in the applicable Final Terms; and 

  

	 	(B)	the product of the Accrual Yield specified in the applicable Final Terms (compounded annually) being applied to the Reference Price from (and including) the Issue Date to (but
excluding) the date fixed for redemption or (as the case may be) the date upon which such Note becomes due and repayable, 

  
 or such other amount as is provided in the applicable Final Terms. 
  
 Where any calculation of an early redemption amount is to be made for a period which is not a whole number of years, the
calculation in respect of the period of less than a full year shall be made on the basis of a 360-day year consisting of 12 months of 30 days each and, in the case of an incomplete month, the number of days elapsed. 
  

	(f)	Instalments 

  
 If the Notes are repayable in instalments, they will be repaid in the Instalment amounts and on the Instalment Date specified in the applicable Final
Terms. 
  

	(g)	Purchases 

  
 The Issuer, the Guarantor or any Subsidiary of the Guarantor may at any time purchase Notes (together, in the case of definitive Notes, with all unmatured
Receipts and Coupons appertaining thereto) in any manner and at any price. In the case of a purchase by tender, such tender must be made available to all Noteholders alike. The Issuer, the Guarantor or any Subsidiary of the Guarantor will be
entitled to hold and deal with Notes so purchased as the Issuer, the Guarantor or the relevant Subsidiary of the Guarantor thinks fit. 
  

 49 

	(h)	Cancellation 

  
 All Notes which are redeemed in full will forthwith be cancelled and Notes which are purchased by or on behalf of the Issuer, the Guarantor or any
Subsidiary of the Guarantor may, at the election of the Issuer, be cancelled (together in each case with all unmatured Receipts and Coupons attached thereto or delivered therewith). Notes purchased by or on behalf of the Issuer, the Guarantor or any
Subsidiary of the Guarantor may not be reissued or resold other than to the Issuer, the Guarantor or any Subsidiary of the Guarantor. 
  

	(i)	Late Payment on Zero Coupon Notes 

  
 If the amount payable in respect of any Zero Coupon Note upon redemption of such Zero Coupon Note pursuant to paragraph (a), (b), (d) or
(e) above or upon its becoming due and repayable as provided in Condition 11 is improperly withheld or refused, the amount due and repayable in respect of such Zero Coupon Note shall be the amount calculated as provided in paragraph
(e) above as though the references therein to the date fixed for redemption or the date upon which the Zero Coupon Note becomes due and repayable were replaced by references to the date which is the earlier of: 
  

	 	(1)	the date on which all amounts due in respect of the Zero Coupon Note have been paid; and 

  

	 	(2)	the date on which the full amount of the moneys payable has been received by the Agent and notice to that effect has been given in accordance with Condition 15.

  
 7. Payments 
  

	(a)	Method of Payment 

  
 Subject as provided below: 
  

	 	(i)	payments in a currency other than euro will be made by transfer to an account in the relevant Specified Currency maintained by the payee with, or by a cheque in such Specified
Currency drawn on, a bank in the principal financial centre of the country of such Specified Currency; and 

  

	 	(ii)	payments in euro will be made by transfer to a euro account (or any other account to which euro may be credited or transferred) maintained by the payee with a bank in the principal
financial centre of any Participating Member State of the European Communities. 

  
 Payments will be subject in all cases to any fiscal or other laws and regulations applicable thereto in the place of payment, but without prejudice to the provisions of Condition 10. 
  
 In these Conditions: 
  
 “Euro zone” means the zone comprising the Member States of the
European Union which adopt or have adopted the euro as their lawful currency in accordance with the Treaty; 
  
 “Participating Member State” means a Member State of the European Communities which adopt or have adopted the euro as its lawful currency in
accordance with the Treaty; and 
  
 “Treaty” means the
Treaty establishing the European Communities, as amended. 
  

	(b)	Presentation of Notes, Receipts, Coupons and Talons 

  
 Payments of principal in respect of definitive Notes will (subject as provided below) be made in the manner provided in paragraph (a) above against
surrender of definitive Notes and payments of interest in respect of definitive Notes will (subject as provided below) be made as aforesaid against surrender of Coupons, in each case at the specified office of any Paying Agent outside the United
States. 
  
 Payments of instalments (if any) of principal, other
than the final instalment, will (subject as provided below) be made against presentation and surrender of the relevant Receipt. Each Receipt must be presented for payment of the relevant instalment together with the definitive Note to which it
appertains. Receipts presented without the definitive Notes to which they appertain do not constitute valid obligations of the Issuer. Upon the date on which any definitive Note becomes due and repayable, unmatured Receipts (if any) appertaining
thereto (whether or not attached) shall become void and no payment shall be made in respect thereof. 
  

 50 

 Fixed Rate Notes in definitive form (other than Dual Currency Notes or Index Linked Notes) should be
presented for payment together with all unmatured Coupons appertaining thereto (which expression shall for this purpose include Coupons falling to be issued on exchange of matured Talons) failing which the amount of any missing unmatured Coupon (or,
in the case of payment not being made in full, the same proportion of the amount of such missing unmatured Coupon as the sum so paid bears to the sum due) will be deducted from the sum due for payment. Each amount of principal so deducted will be
paid in the manner mentioned above against surrender of the relative missing Coupon at any time before the expiry of ten years after the Relevant Date (as defined in Condition 10) in respect of such principal (whether or not such Coupon would
otherwise have become void under Condition 14) or, if later, five years from the date on which such Coupon would otherwise have become due. Upon any Fixed Rate Note becoming due and repayable prior to its Maturity Date, all unmatured Talons (if any)
appertaining thereto will become void and no further Coupons will be issued in respect thereof. 
  
 Upon the date on which any Floating Rate Note, Dual Currency Note or Indexed Note in definitive form becomes due and repayable, unmatured Coupons and
Talons (if any) relating thereto (whether or not attached) shall become void and no payment or, as the case may be, exchange for further Coupons shall be made in respect thereof. 
  
 If the due date for redemption of any definitive Note is not a Fixed Interest Date or an Interest Payment Date, interest (if
any) accrued in respect of such Note from (and including) the preceding Fixed Interest Date or Interest Payment Date or, as the case may be, the Interest Commencement Date shall be payable only against surrender of the relevant definitive Note.

  
 Payments of principal and interest (if any) in respect of
Notes represented by any global Note will (subject as provided below) be made in the manner specified above in relation to definitive Notes and otherwise in the manner specified in the relevant global Note against presentation or surrender, as the
case may be, of such global Note at the specified office of the Agent. A record of each payment made against presentation or surrender of such global Note, distinguishing between any payment of principal and any payment of interest, will be made on
such global Note by the Agent and such record shall be prima facie evidence that the payment in question has been made. 
  
 The holder of the relevant global Note shall be the only person entitled to receive payments in respect of Notes represented by such global Note and the
Issuer or, as the case may be, the Guarantor will be discharged by payment to, or to the order of, the holder of such global Note in respect of each amount so paid. Each of the persons shown in the records of Euroclear or Clearstream, Luxembourg as
the holder of a particular nominal amount of Notes must look solely to Euroclear or Clearstream, Luxembourg, as the case may be, for his share of each payment so made by the Issuer or, as the case may be, the Guarantor to, or to the order of, the
holder of the relevant global Note. No person other than the holder of the relevant global Note shall have any claim against the Issuer or, as the case may be, the Guarantor in respect of any payments due on that global Note. 
  
 Payments of interest in respect of the Notes will be made at the specified
office of a Paying Agent in the United States (which expression, as used herein, means the United States of America (including the States and the District of Columbia, its territories, its possessions and other areas subject to its jurisdiction))
if: 
  

	 	(i)	the Issuer has appointed Paying Agents with specified offices outside the United States with the reasonable expectation that such Paying Agents would be able to make payment at such
specified offices outside the United States of the full amount of interest on the Notes in the manner provided above when due; 

  

	 	(ii)	payment of the full amount of such interest at such specified offices outside the United States is illegal or effectively precluded by exchange controls or other similar
restrictions; and 

  

	 	(iii)	such payment is then permitted under United States law without involving, in the opinion of the Issuer and the Guarantor, adverse tax consequences to the Issuer.

  

	(c)	Redenomination 

  
 Where Redenomination is specified in the applicable Final Terms as being applicable, the Issuer may, without the consent of the Noteholders or the holders
of related Receipts or Coupons on giving at least 30 days’ prior notice to the Noteholders in accordance with Condition 15, elect 

  

 51 

 
that, with effect from the Redenomination Date specified in the notice, the Notes shall be redenominated in euro. The election will have effect as follows:

  

	 	(i)	each Specified Denomination will be deemed to be denominated in such amount of euro as is equivalent to its denomination in the Specified Currency at the Established Rate, subject
to such provisions (if any) as to rounding (and payments in respect of fractions consequent on rounding) as the Issuer may decide, and as may be specified in the notice; 

  

	 	(ii)	after the Redenomination Date, all payments in respect of the Notes, the Receipts and the Coupons will be made solely in euro, including payments of interest in respect of periods
before the Redenomination Date, as though references in the Notes to the Specified Currency were to euro; and 

  

	 	(iii)	such changes shall be made to these Conditions as the Issuer may decide and as may be specified in the notice, to conform them to conventions then applicable to instruments
denominated in euro or to enable the Notes to be consolidated with one or more issues of other notes, whether or not originally denominated in the Specified Currency or euro. 

  

	(d)	Exchangeability 

  
 Where Exchangeability is specified in the applicable Final Terms as being applicable, the Issuer may without the consent of the Noteholders or the holders
of related Receipts or Coupons, on giving at least 30 days’ prior notice to the Noteholders in accordance with Condition 15, elect that, with effect from the Redenomination Date or such later date for payment of interest under the Notes as it
may specify in the notice, the Notes shall be exchangeable for Notes expressed to be denominated in euro in accordance with such arrangements as the Issuer may decide and as may be specified in the notice, including arrangements under which Receipts
and Coupons unmatured at the date so specified become void. 
  
 In
this Condition, the following expressions have the following meanings: 
  
 “Established Rate” means the rate for conversion of the Specified Currency (including compliance with rules relating to roundings in accordance with applicable European Community regulations) into euro established by the Council
of the European Union pursuant to Article 109(4) of the Treaty; 
  
 “Redenomination Date” means any date for payment of interest under the Notes specified by the Issuer which falls on or after the date on which the country of the Specified Currency participates in European Economic and Monetary
Union pursuant to the Treaty. 
  

	(e)	Payment Day 

  
 If the date for payment of any amount in respect of any Note, Receipt or Coupon is not a Payment Day, the holder thereof shall not be entitled to payment
until the next following Payment Day in the relevant place and shall not be entitled to further interest or other payment in respect of such delay. For these purposes, unless otherwise specified in the applicable Final Terms, “Payment Day”
means any day which is both: 
  

	 	(i)	a day (other than a Saturday or a Sunday) on which banks are open for business in 

  

	 	(A)	the relevant place of presentation, London and Madrid: and 

  

	 	(B)	any Additional Financial Centre specified in the applicable Final Terms; and 

  

	 	(ii)	either (1) in relation to Notes denominated in a Specified Currency other than euro, a day on which commercial banks and foreign exchange markets settle payments in the
principal financial centre of the relevant Specified Currency (if other than London and which if the Specified Currency is Australian dollars shall be Melbourne) or (2) in relation to notes denominated in euro, a day on which the TARGET System
(as defined in Condition 5(b)(iv) is operating). 

  

	(f)	Interpretation of Principal and Interest 

  
 Any reference in these Conditions to principal in respect of the Notes shall be deemed to include, as applicable: 
  

	 	(i)	any additional amounts which may be payable with respect to principal under Condition 10; 

  

 52 

	 	(ii)	the Final Redemption Amount of the Notes; (iii) the Early Redemption Amount of the Notes; 

  

	 	(iv)	the Optional Redemption Amount(s) (if any) of the Notes; 

  

	 	(v)	in relation to Notes redeemable in instalments, the Instalment Amounts; and 

  

	 	(vi)	any premium and any other amounts which may be payable under or in respect of the Notes. 

  
 Any reference in these Conditions to interest in respect of the Notes shall be deemed to include, as applicable, any
additional amounts which may be payable with respect to interest under Condition 10. 
  
 8. Agent and Paying Agents 
  
 The names of the
initial Agent and the other initial Paying Agents and their initial specified offices are set out below. 
  
 The Issuer and the Guarantor are entitled to vary or terminate the appointment of any Paying Agent and/or appoint additional or other Paying Agents and/or
approve any change in the specified office through which any Paying Agent acts, provided that: 
  

	 	(i)	so long as the Notes are admitted to listing, trading and/or quotation by any listing authority, stock exchange and/or quotation system, there will at all times be a Paying Agent
with a specified office in such place as may be required by the rules and regulations of the relevant listing authority, stock exchange and/or quotation system; 

  

	 	(ii)	there will at all times be a Paying Agent with a specified office acting in continental Europe; 

  

	 	(iii)	there will at all times be an Agent; and 

  

	 	(iv)	each of the Issuer and the Guarantor will ensure that it maintains a Paying Agent in an EU Member State that will not be obliged to withhold or deduct tax pursuant to European
Council Directive 2003/48/EC or any other Directive implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000. 

  
 In addition, the Issuer and the Guarantor shall forthwith appoint a Paying Agent having a specified office in New York City in the circumstances described
in the final paragraph of Condition 7(b). Any variation, termination, appointment or change shall only take effect (other than in the case of insolvency, when it shall be of immediate effect) after not less than 30 nor more than 45 days’ prior
notice thereof shall have been given to the Noteholders in accordance with Condition 15 provided that no such variation, termination, appointment or change shall take effect (except in the case of insolvency) within 15 days before or after any Fixed
Interest Date or Interest Payment Date, as the case may be. 
  
 9. Exchange of
Talons 
  
 On and after the Fixed Interest Date or the
Interest Payment Date, as appropriate, on which the final Coupon comprised in any Coupon sheet matures, the Talon (if any) forming part of such Coupon sheet may be surrendered at the specified office of the Agent or any other Paying Agent in
exchange for a further Coupon sheet including (if such further Coupon sheet does not include Coupons to (and including) the final date for the payment of interest due in respect of the Notes to which it appertains) a further Talon, subject to the
provisions of Condition 13. Each Talon shall, for the purposes of these Conditions, be deemed to mature on the Fixed Interest Date or the Interest Payment Date (as the case may be) on which the final Coupon comprised in the relative Coupon sheet
matures. 
  
 10. Taxation 
  
 All amounts payable (whether in respect of principal, redemption amount,
interest or otherwise) in respect of the Notes will be made free and clear of and without withholding or deduction for or on account of any present or future taxes, duties, assessments or governmental charges of whatever nature imposed or levied by
or on behalf of the Kingdom of Spain or any political subdivision thereof or any authority or agency therein or thereof having power to tax, unless the withholding or deduction of such taxes, duties, assessments or governmental charges is 

  

 53 

 
required by law. In that event, the Issuer, failing which the Guarantor, will pay such additional amounts as may be necessary in order that the net amounts
receivable by any Noteholder after such withholding or deduction shall equal the respective amounts which would have been receivable by such Noteholder in the absence of such withholding or deduction; except that no such additional amounts shall be
payable in relation to any payment in respect of any Notes or Coupon: 
  

	 	(i)	to, or to a third party on behalf of, a Noteholder who is liable to such taxes, duties, assessments or governmental charges in respect of such Notes by reason of his having some
connection with the Kingdom of Spain other than the mere holding of such Notes or Coupon; or 

  

	 	(ii)	presented for payment more than thirty days after the Relevant Date, except to the extent that the relevant Noteholder would have been entitled to such additional amounts on
presenting the same for payment on the expiry of such period of thirty days; or 

  

	 	(iii)	where such withholding or deduction is imposed on a payment to an individual and is required to be made pursuant to European Union Directive 2003/48/EC or any other Directive
implementing the conclusions of the ECOFIN Council meeting of 26-27 November 2000 on the taxation of savings income or any law implementing or complying with, or introduced in order to conform to, such Directive; or 

  

	 	(iv)	presented for payment by or on behalf of a Noteholder who would have been able to avoid such withholding or deduction by presenting the relevant Note or Coupon to another Paying
Agent in a member state of the European Union; or 

  

	 	(v)	to, or to a third party on behalf of, a Noteholder in respect of whom the Issuer or the Guarantor does not receive such information (which may include a tax residence certificate)
concerning such Noteholder’s identity and tax residence as it may require in order to comply with Law 13/1985 and any implementing legislation; or 

  

	 	(vi)	to, or to a third party on behalf of, individuals resident for tax purposes in The Kingdom of Spain or a resident in a tax haven (as defined in Royal Decree 1080/1991 of
5 July, as amended from time to time); or 

  

	 	(vii)	to, or to a third party on behalf of, a Spanish-resident legal entity subject to Spanish corporation tax if the Spanish tax authorities determine that the Notes do not comply with
exemption requirements specified in the Reply to a Consultation of the Directorate General for Taxation (Dirección General de Tributos) dated 27 July 2004 and require a withholding to be made. 

  
 A list of the tax havens referred to in paragraph (vi) of this
Condition 10 as at 17 November 2005 is set out in the base prospectus relating to the Notes under “Taxation and Disclosure of Noteholder Information in Connection with Interest Payments – Taxation in Spain – Issues by Gas Natural

jurídico de los movimientos de capitales y de las transacciones económicas con el exterior y sobre determinadas medidas del blanqueo de capitales); and 
  
 “Relevant Date” means, in respect of any payment, the date on which such payment first becomes due and payable,
but if the full amount of the moneys payable has not been received by the Agent on or prior to such due date, it means the first date on which, the full amount of such moneys having been so received and being available for payment to Noteholders,

 12.
Syndicate of Noteholders 
  
 The Noteholders of the relevant
Series shall meet in accordance with the regulations governing the relevant Syndicate of Noteholders (the “Regulations”). The Regulations shall contain the rules governing the functioning of each Syndicate and the rules governing its
relationship with the Issuer and shall be attached to the relevant Public Deed (as defined in the introduction to these Conditions). Pro forma Regulations are included in the Agency Agreement. 
  
 A temporary Commissioner will be appointed for each Syndicate. Upon the
subscription of the Notes, the temporary Commissioner will call a general meeting of the Syndicate to ratify or oppose the acts of the temporary Commissioner, confirm his appointment or appoint a substitute and to ratify the Regulations. 

 
 Provisions for meetings of Syndicates of Noteholders will be contained in
the Regulations relating to the relevant Series and in the Agency Agreement. Such Regulations shall have effect as if incorporated herein. 
  
 The Issuer may, with the consent of the Fiscal Agent and the relevant Commissioner, but without the consent of the holders of the Notes of any Series or
Coupons, amend these Conditions and the Deed of Covenant insofar as they may apply to such Notes to correct a manifest error. Subject as aforesaid, no other modification may be made to these Conditions or the Deed of Covenant except with the
sanction of a resolution of the relevant Syndicate of Noteholders. 
  

 56 

 For the purposes of these Conditions, 
  

	 	(i)	“Commissioner” means the comisario as this term is defined under the Spanish Corporations Law (Ley de Sociedades Anónimas) of each Syndicate of Noteholders;
and 

  

	 	(ii)	“Syndicate of Noteholders” means the sindicato as this term is described under the Spanish Corporations law (Ley de Sociedades Anónimas).

  
 Noteholders shall, by virtue of purchasing
Notes, be deemed to have agreed to the appointment of the temporary Commissioner for the relevant Series named in the relevant Final Terms and to have become a member of the relevant Syndicate of Noteholders. 
  
 13. Replacement of Notes, Receipts, Coupons and Talons 
  
 Should any Note, Receipt, Coupon or Talon be lost, stolen, mutilated,
defaced or destroyed, it may be replaced at the specified office of the Agent in London (or such other place as may be notified to the Noteholders), subject to all applicable laws and listing authority, stock exchange and/or quotation system
requirements upon payment by the claimant of the expenses incurred in connection therewith and on such terms as to evidence and indemnity as the Issuer and the Guarantor may reasonably require. Mutilated or defaced Notes, Receipts, Coupons or Talons
must be surrendered before replacements will be issued. 
  
 14. Prescription

  
 The Notes, Receipts and Coupons will become void unless
presented for payment within a period of ten years (in the case of principal) and five years (in the case of interest) after the Relevant Date (as defined in Condition 10) therefor. 
  
 There shall not be included in any Coupon sheet issued on exchange of a Talon any Coupon the claim for payment in respect of
which would be void pursuant to this Condition 14 or Condition 7(b) or any Talon which would be void pursuant to Condition 7(b). 
  
 15. Notices 
  
 All notices regarding the Notes shall be valid if published in one or more leading English language daily newspapers with circulation in the United
Kingdom. It is expected that publication of notices will normally be made in the Financial Times in the United Kingdom. Any such notice shall be deemed to have been given on the date of the first publication. 
  
 Until such time as any definitive Notes are issued, there may, so long as the
global Note(s) is or are held in its or their entirety on behalf of Euroclear and/or Clearstream, Luxembourg, be substituted for such publication in such newspaper the delivery of the relevant notice to Euroclear and/or Clearstream, Luxembourg, as
appropriate, for communication by them to the Noteholders. Any such notice shall be deemed to have been given to the Noteholders on the seventh day after the day on which the said notice was given to Euroclear and/or Clearstream, Luxembourg, as
appropriate. 
  
 Notices to be given by any Noteholder shall be in
writing and given by lodging the same, together with the relative Note or Notes, with the Agent. Whilst any of the Notes are represented by a global Note, such notice may be given by any Noteholder to the Agent via Euroclear and/or Clearstream,
Luxembourg, as the case may be, in such manner as the Agent and Euroclear and/or Clearstream, Luxembourg, as the case may be, may approve for this purpose. 
  
 Copies of any notice given to any Noteholders will be also given to the Commissioner of the Syndicate of Noteholders of the relevant Series. 

 
 16. Further Issues 
  
 The Issuer shall be at liberty from time to time without the consent of the Noteholders to create and issue further notes
ranking pari passu in all respects (or in all respects save for the first payment of interest thereon) with the outstanding Notes and so that the same shall be consolidated and form a single series with the outstanding Notes.

substitute under this Condition 17); 

  

	 	(iii)	if the Substituted Debtor is resident for tax purposes in a territory (the “New Residence”) other than that in which the Issuer prior to such substitution was resident for
tax purposes (the “Former Residence”) the Documents contain an undertaking and/or such other provisions as may be necessary to ensure that each Noteholder of the Relevant Notes has the benefit of an undertaking in terms corresponding to
the provisions of Condition 10, with, where applicable, the substitution of references to the Former Residence with references to the New Residence; 

  

	 	(iv)	the Guarantor guarantees the obligations of the Substituted Debtor in relation to outstanding Relevant Notes; 

  

	 	(v)	the Substituted Debtor, the Issuer and the Guarantor have obtained all necessary governmental approvals and consents for such substitution and for the performance by the Substituted
Debtor of its obligations under the Documents and for the performance by the Guarantor of its obligations under the Guarantee as they relate to the obligations of the Substituted Debtor under the Documents; 

  

	 	(vi)	each stock exchange on which the Relevant Notes are listed shall have confirmed that, following the proposed substitution of the Substituted Debtor, the Relevant Notes will continue
to be listed on such stock exchange; 

  

	 	(vii)	a legal opinion shall have been delivered to the Commissioner and the Agent (from whom copies will be available) from lawyers of recognised standing in the country of incorporation
of the Substituted Debtor, confirming, as appropriate, that upon the substitution taking place (A) the requirements of this Condition 17, save as to the giving of notice to the Noteholders have been met and (B) the Notes, Coupons and
Talons are legal, valid and binding obligations of the Substituted Debtor enforceable in accordance with their terms; 

  

	 	(viii)	Moody’s Investors Service Limited and Standard and Poor’s Ratings Services, a Division of The McGraw-Hill Companies (or any other rating agency which has issued a rating
in connection with the Relevant Notes) shall have confirmed that following the proposed substitution of the Substituted Debtor, the credit rating of the Relevant Notes will not be adversely affected; and 

  

	 	(ix)	if applicable, the Substituted Debtor has appointed a process agent as its agent in England to receive service of process on its behalf in relation to any legal proceedings arising
out of or in connection with the Relevant Notes and any Coupons. 

  

	 	(b)	Upon the execution of the Documents and the delivery of the legal opinions, the Substituted Debtor shall succeed to, and be substituted for, and may exercise every right and power,
of the Issuer under the Relevant Notes and the Agency Agreement with the same effect as if the Substituted Debtor had been named as the Issuer herein, and the Issuer shall be released from its obligations under the Relevant Notes and under the
Agency Agreement. 

  

 58 

	 	(c)	After a substitution pursuant to Condition 17(a), the Substituted Debtor may, without the consent of any Noteholder, effect a further substitution. All the provisions specified in
Condition 17(a) and 17(b) shall apply mutatis mutandis, and references in these Conditions to the Issuer shall, where the context so requires, be deemed to be or include references to any such further Substituted Debtor.

  

	 	(d)	After a substitution pursuant to Condition 17(a) or 17(c) any Substituted Debtor may, without the consent of any Noteholder, reverse the substitution, mutatis mutandis.

  

	 	(e)	The Documents shall be delivered to, and kept by, the Agent. Copies of the Documents will be available free of charge at the specified office of each of the Agents.

  
 18. Governing Law; Submission to Jurisdiction 

 
 Save as described below the Agency Agreement, the Deed of Covenant, the
Deed of Guarantee and the Notes are governed by, and shall be construed in accordance with, English law. Conditions 2 and 3 and the provisions of Condition 12 relating to the appointment of the Commissioner and the Syndicate of Noteholders are
governed by, and shall be construed in accordance with, Spanish law. The Issuer and the Guarantor irrevocably agree for the benefit of the Noteholders that the courts of England shall have jurisdiction to hear and determine any suit, action or
proceedings, and to settle any disputes (together “Proceedings”), which may arise out of or in connection with the Agency Agreement, the Deed of Covenant, the Deed of Guarantee and the Notes and, for such purpose, irrevocably submit to the
jurisdiction of such courts. 
  
 The Issuer and the Guarantor
irrevocably and unconditionally waive and agree not to raise any objection which any of them may have now or subsequently to the laying of the venue of any Proceedings in the courts of England and any claim that any Proceedings have been brought in
an inconvenient forum and further irrevocably and unconditionally agree that a judgment in any Proceedings brought in the courts of England shall be conclusive and binding upon each of them and may be enforced in the courts of any other
jurisdiction. Nothing in this Condition shall limit any right to take Proceedings against the Issuer and/or the Guarantor in any other court of competent jurisdiction, nor shall the taking of Proceedings in one or more jurisdictions preclude the
taking of Proceedings in any other jurisdiction, whether concurrently or not. 
  
 The Issuer and the Guarantor irrevocably and unconditionally appoint Law Debenture Corporation at Fifth Floor, 100 Wood Street, London EC2V 7EX as agent for service of process in England in respect of any Proceedings
and undertake that in the event of it ceasing so to act the Issuer and the Guarantor will forthwith appoint a further person as their agent for that purpose and notify the name and address of such person to the Agent and agree that, failing such
appointment within fifteen days, any Noteholder shall be entitled to appoint such a person by written notice addressed to the Issuer and the Guarantor and delivered to the Issuer and the Guarantor or to the specified office of the Agent. Nothing
contained herein shall affect the right of any Noteholder to serve process in any other manner permitted by law. 
  
 19. Rights of Third Parties 
  
 No person shall have any right to enforce any term or condition of any Notes under the Contracts (Rights of Third Parties) Act 1999. 
  

 59 

 FORM OF THE NOTES 
  
 Each Tranche of Notes will be initially represented by a Temporary Global Note without receipts, interest coupons or talons,
which will be delivered to a common depositary for Euroclear, Clearstream, Luxembourg and/or any other relevant clearing system. Whilst any Note is represented by a Temporary Global Note, payments of principal and interest (if any) due prior to the
Exchange Date (as defined below) will be made against presentation of the Temporary Global Note only to the extent that certification (in a form to be provided) as required by U.S. Treasury regulations, has been received by Euroclear, Clearstream,
Luxembourg and/or any other relevant clearing system has given a like certification (based on the certifications it has received) to the Agent. 
  
 On and after the date (the “Exchange Date”) which is 40 days after the date on which any Temporary Global Note is issued, interests in such
Temporary Global Note will be exchanged (free of charge) either for interests in a Permanent Global Note without receipts, interest coupons or talons or for definitive Notes with, where applicable, receipts, interest coupons and talons attached (as
indicated in the applicable Final Terms) in each case against certification of beneficial ownership as described in the second sentence of the immediately preceding paragraph. Holders of interests in any Temporary Global Note shall not (unless, upon
due presentation of such Temporary Global Note for exchange (in whole but not in part only) for a Permanent Global Note or for delivery of definitive Notes, such exchange or delivery is improperly withheld or refused and such withholding or refusal
is continuing at the relevant payment date) be entitled to receive any payment in respect of the Notes represented by such Temporary Global Note which falls due on or after the Exchange Date or be entitled to exercise any option on a date after the
Exchange Date. 
  
 Payments of principal and interest (if any) on
a Permanent Global Note will be made through Euroclear, Clearstream, Luxembourg and/or any other relevant clearing system against presentation or surrender (as the case may be) of the Permanent Global Note without any requirement for certification.
Unless otherwise specified in the applicable Final Terms, a Permanent Global Note will be exchangeable (free of charge), in whole but not in part for definitive Notes with, where applicable, receipts, interest coupons and talons attached upon not
less than 60 days’ written notice to the Agent as described therein. Global Notes and definitive Notes will be issued pursuant to the Agency Agreement. 
  
 So long as the Notes are represented by a Temporary Global Note or a Permanent Global Note and the relevant clearing system(s) so permit, the Notes shall
be tradeable in minimum principal amounts of €50,000 and integral multiples of €1,000 thereafter or, in each case, its equivalent in the relevant currency of the Notes on the relevant date of issue. 
  
 The following legend will appear on all global Notes, definitive Notes,
receipts, interest coupons and talons: 
  
 “Any United States person who
holds this obligation will be subject to limitations under the United States income tax laws, including the limitations provided in Sections 165(j) and 1287(a) of the Internal Revenue Code.” 
  
 The sections referred to provide that holders who are United States persons
(as defined in the United States Revenue Code of 1986, as amended), with certain exceptions, will not be entitled to deduct any loss on Notes, receipts or interest coupons and will not be entitled to capital gains treatment of any gain on any sale,
disposition, redemption or payment of principal in respect of Notes, receipts or interest coupons. 
  
 A Note may be accelerated by the holder thereof in certain circumstances described in “Terms and Conditions of Notes issued by Gas Natural Finance
B.V. - Events of Default” and “Terms and Conditions of Notes issued by Gas Natural Capital Markets, S.A. - Events of Default”. In such circumstances, where any Note is still represented by a global Note and a holder of such Note so
represented and credited to his securities account with Euroclear or Clearstream, Luxembourg gives notice that it wishes to accelerate such Note, unless within a period of 15 days from the giving of such notice payment has been made in full of the
amount due in accordance with the terms of such global Note, such global Note will become void. At the same time, holders of interests in such global Note credited to their accounts with Euroclear or Clearstream, Luxembourg will become entitled to
proceed directly against the relevant Issuer on the basis of statements of account provided by Euroclear and Clearstream, Luxembourg, on and subject to the terms of a deed of covenant (the “Deed of Covenant”) dated 17 November 2005
executed by the relevant Issuer.

	2.2	As a separate, additional and continuing obligation, the Guarantor unconditionally and irrevocably undertakes with each Beneficiary that, should any amount referred to in Clause 2.1
not be recoverable from the Guarantor thereunder for any reason whatsoever (including, without limitation, by reason of any Note, any provision of any Note, the relevant Deed of Covenant or any provision thereof being or becoming void, unenforceable
or otherwise invalid under any applicable law) then, notwithstanding that the same may have been known to such Holder or Relevant Account Holder, the Guarantor will, as a sole, original and independent obligor, upon first written demand under Clause

perform and comply with the obligations expressed to be undertaken by it in the Conditions. 
  
 4. PRESERVATION OF RIGHTS 
  

	4.1	The obligations of the Guarantor herein contained shall be deemed to be undertaken as sole or principal debtor. 

  

	4.2	The obligations of the Guarantor herein contained shall constitute and be continuing obligations notwithstanding any settlement of account or other matters or things whatsoever and,

Note and the relevant Deed of Covenant until final repayment in full of all amounts owing by the relevant Issuer, and total satisfaction of all the actual and contingent obligations of such Issuer under such Note or such Deed of Covenant.

  

	4.3	Neither the obligations of the Guarantor herein contained nor the rights, powers and remedies conferred upon the Beneficiaries or any of them by this Deed of Guarantee or by law
shall be discharged, impaired or otherwise affected by: 

  

	 	(a)	the winding-up, liquidation or dissolution of the relevant Issuer, or analogous proceedings in any jurisdiction or any change in status, function, control or ownership of the

	4.4	Any settlement or discharge between the Guarantor and the Beneficiaries or any of them shall be conditional upon no payment to the Beneficiaries or any of them by the relevant
Issuer, or any other person on behalf of the relevant Issuer being avoided or reduced by virtue of any provisions or enactments relating to bankruptcy, insolvency or liquidation for the time being in force and, in the event of any such payment being
so avoided or reduced, the Beneficiaries shall each be entitled to recover the amount by which such payment is so avoided or reduced from the Guarantor subsequently as if such settlement or discharge had not occurred. 

  

	4.5	No Beneficiary shall be obliged before exercising any of the rights, powers or remedies conferred upon it by this Deed of Guarantee or by law: 

  

	 	(f)	to make any demand of the relevant Issuer other than the presentation of the relevant Note; or

to whom the benefit of the Guarantor’s obligations are given; and/or

 7. PROVISIONS SEVERABLE 
  
 Each of the provisions in this Deed of Guarantee shall be severable and distinct from the others and the illegality, invalidity or unenforceability of any
one or more provisions under the law of any jurisdiction shall not affect or impair the legality, validity or enforceability of any other provisions in that jurisdiction nor the legality, validity or enforceability of any provisions under the law of
any other jurisdiction. 
  
 8. CURRENCY INDEMNITY 
  
 If any sum due from the Guarantor under this Deed of Guarantee or any order
or judgment given or made in relation thereto has to be converted from the currency (the “first currency”) in which the same is payable under this Deed of Guarantee or such order or judgment into another currency (the
“second currency”) for the purpose of (a) making or filing a claim or proof against the Guarantor, (b) obtaining an order or judgment in any court or other tribunal or (c) enforcing any order or judgment given or made
in relation to this Deed of Guarantee, the Guarantor shall indemnify each Beneficiary on demand against any loss suffered as a result of any discrepancy between (i) the rate of exchange used for such purpose to convert the sum in question from
the first currency into the second currency and (ii) the rate or rates of exchange at which such Beneficiary may in the ordinary course of business purchase the first currency with the second currency upon receipt of a sum paid to it in
satisfaction, in whole or in part, of any such order, judgment, claim or proof. 
  
 This indemnity constitutes a separate and independent obligation of the Guarantor and shall give rise to a separate and independent cause of action. 
  
 9. NOTICES 
  
 Notices to the Guarantor will be deemed to be validly given if delivered at Av. Portal de l’Angel, 22,08002 Barcelona, Spain (or at such other
address and for such other attention as may have been notified to Holders in accordance with the Conditions) and will be deemed to have been validly given at the opening of business on the next day on which the Guarantor’s principal office is
open for business. 
  
 10. LAW AND JURISDICTION 
  

	10.1	Governing law 

  
 This Deed of Guarantee and all matters arising from or connected with it are governed by, and shall be construed in accordance with, English law.

  

	10.2	English courts 

  
 The courts of England have exclusive jurisdiction to settle any dispute (a “Dispute”), arising from or connected with this Deed of
Guarantee (including a dispute regarding the existence, validity or termination of this Deed of Guarantee) or the consequences of its nullity. 
  

	10.3	Appropriate forum 

  
 The Guarantor agrees that the courts of England are the most appropriate and convenient courts to settle any Dispute and, accordingly, that it will not
argue to the contrary. 
  

	10.4	Rights of the Beneficiaries to take proceedings outside England 

  
 Clause 10.2 (English courts) is for the benefit of the Beneficiaries only. As a result, nothing in this Clause 10 (Law and
jurisdiction) prevents the Beneficiaries from taking proceedings relating to a Dispute (“Proceedings”) in any other courts with jurisdiction. To the extent allowed by law, the Beneficiaries may take concurrent Proceedings in
any number of jurisdictions. 
  

 64 

	10.5	Process agent 

  
 The Guarantor agrees that the documents which start any Proceedings and any other documents required to be served in relation to those Proceedings may be
served on it by being delivered to Law Debenture Corporate Services Limited at Fifth Floor, 100 Wood Street, London EC2Y 7EX or, if different, its registered office for the time being or at any address of the Guarantor in Great Britain at which
process may be served on it in accordance with Part XXIII of the Companies Act 1985. If such person is not or ceases to be effectively appointed to accept service of process on behalf of the Guarantor, the Guarantor shall, on the written demand of
any Beneficiary addressed and delivered to the Guarantor appoint a further person in England to accept service of process on its behalf and, failing such appointment within 15 days, any Beneficiary shall be entitled to appoint such a person by
written notice addressed to the Guarantor and delivered to the Guarantor. Nothing in this paragraph shall affect the right of any Beneficiary to serve process in any other manner permitted by law. This clause applies to Proceedings in England and to
Proceedings elsewhere.

 DESCRIPTION OF GAS NATURAL SDG, S.A. 
  
 Incorporation and Status

Anónimas (Spanish companies law) as a Sociedad Anónima (limited liability company) registered in the Commercial Registry of Barcelona at Tome 22147, folio 147, Page B-33172. The registered office of Gas Natural is at Av.
Portal de l’Angel, 22 08002 Barcelona, Spain and the telephone number is +34 93 402 58 91. 
  
 Share Capital 
  
 Gas
Natural’s share capital is made up of 447,776,028 shares of euro 1 par value each, represented by book entries and forming a single class. The share capital of Gas Natural is euro 447,776,028 and is fully subscribed and paid up. 
  
 Historical background 
  
 Gas Natural is the parent company of the Gas Natural group (composed of Gas Natural SDG, S.A. and its consolidated
subsidiaries) (the “Group”). 
  
 The Group is the result
of a restructuring of the natural gas sector in Spain. In 1991 Catalana de Gas and Gas Madrid merged and acquired piped gas distribution assets of Repsol creating Gas Natural SDG, S.A. 
  
 The Group is an energy services multinational group focussing on the supply, distribution and commercialisation of natural
gas in Spain, Latin America and Italy, with almost 10 million customers. Since December 2000, the Group has been selling electricity in the liberalised electricity market and since March 2002, it has produced electricity in Spain. 

 
 Recent Developments 
  
 In 2004, the Group commenced natural gas production after being awarded, together with Repsol YPF in Algeria, a gas
prospecting project (Gassi Chergui) and an integrated liquefied natural gas project (Gassi Touil) which will enable it to have its own reserves for the first time. 
  
 In 2005 Gas Natural signed an agreement with Repsol YPF for the joint development of liquefied natural gas businesses
(“LNG”) by forming an LNG transport company. 
  
 In
April 2005, Gas Natural acquired Desarrollo de Energías Renovables (DERSA), which has a strong presence in the Spanish wind energy market and a substantial portfolio of wind farms under development. 
  
 In July 2005, Gas Natural commenced supplying gas in France and obtained its
first customers in that country. 
  
 In addition, Gas Natural is
developing its investment plan for the year 2005, focusing mainly on completing the construction of combined cycle units for the electricity business and extending the distribution grid of gas in Spain. 
  
 On 5 September 2005, Gas Natural submitted for its approval by the
Spanish Securities Market Commission (Comisión Nacional del Mercado de Valores) and the relevant regulatory bodies a tender offer over 100 per cent of the share capital of Endesa, Spain’s largest electricity company,
conditional upon its acceptance by shareholders of Endesa holding at least 75 per cent of its share capital and upon the removal of existing limitations in the by-laws of Endesa. 
  
 Consideration for the Endesa shares amounts to a total of €22,549 million and will be effected by a combination of new
Gas Natural shares and cash in a proportion of 65.5 per cent. and 34.5 per cent., respectively. Gas Natural has entered into a credit and guarantee facility amounting to €7,806 million to fund the cash element of the consideration for
the Tender Offer. As a result of the increase in the Group’s financial indebtedness Moody’ announced that they have placed the Group’s long-term indebtedness on review for possible downgrade and Standard & Poor’s have
placed the Group’s long-term indebtedness on creditwatch negative which may result in a lower rating for the long-term indebtedness rating for the Group. 
  

As at the date of this Base Prospectus, the Tender Offer has been approved by the Spanish Energy Commission (Comisión Nacional de la
Energía) with certain conditions accepted by Gas Natural and is currently in the authorisation process of the Spanish Securities Market Commission and the relevant competition authorities. 
  

 79 

 Business 
  
 The Group has almost half of its customers in Argentina, Brazil, Colombia and México. 
  
 The current generation programme of the Group includes 1,600 MW of rated output in combined cycles and 610 MW of wind power.

  
 The Group has 11 gas distribution companies in Spain, which
carry on their activities in 12 autonomous communities. In the liberalised market, the Group sells natural gas and electricity via Gas Natural Comercializadora and Gas Natural Services. 
  
 The Group is a majority shareholder in Metragaz and EMPL, which operate and maintain the Moroccan section of the
Maghreb-Europe gas pipeline, which links the Algerian deposits of Hassi R’Mel with the Iberian Peninsula. These companies also own several gas-related companies and other ancillary companies. 
  
 The following table sets out certain gas and electricity output information

shareholding. 
  
 Gas Natural Group businesses 
  
 Gas purchasing by the Group is based on a combination of (i) ensuring
supplies of natural gas to meet expected demand through a mixture of long-term and spot contracts and (ii) diversifying sources of supply to reduce dependence on specific markets. 
  
 The Group handles more than 380 TWh of gas under flexible conditions, a combination of NG and LNG, with 15 supply contracts
in Europe and 21 in America. 
  
 Gas distribution in Spain 
  
 The gas distribution business in Spain includes the remunerated gas
distribution activity, rated sales and secondary transport, together with non-remunerated distribution activities in Spain (for example, meter rentals, customer connections, etc.). The Group carries out this business through eleven regional
distributors: Gas Natural SDG, Gas Natural Cegas, Gas Natural Murcia, Gas Natural Andalucía, Gas Natural Castilla-La Mancha, Gas Natural Castilla y León, Gas Navarra, Gas Natural Rioja, Gas Natural Cantabria, Gas Galicia and Gas
Natural La Coruña. 
  
 For the year ended 31 December
2004, regulated gas sales in Spain, which covers rated gas distribution and marketing and Third Party Network Access services (TPA) totalled 127,065 GWh, 1% higher than in 2003. 
  
 Gas sales in the residential and industrial markets fell by 9.7% and 38.3% respectively in 2004, due to the progressive
transfer of customers to the liberalised market, both to the two Group marketing companies and other marketing companies, as a result of the total liberalisation of the market on 1 January 2003. 
  
 The distribution network grew by over 2,800 kilometres in 2004 to a total of
37,534 kilometres at 31 December 2004, an interannual growth of over 8%. 
  

 80 

 At 31 December 2004, the number of gas distribution customers in Spain reached 4.8 million, up
7.3% over the customer base at 31 December 2003. 
  
 Residential market

  
 The residential market comprises sales of natural gas to
households, commercial customers and small industries, primarily for heating homes and business premises, water heating, cooking and the operation of dryers, air conditioners and other appliances. Commercial customers are principally service
companies and entities in the public sector, including schools and hospitals, offices, shops, public buildings, hotels and restaurants. In the residential market, natural gas competes mainly with electricity, coal, fuel oil and liquid petroleum gas
(“LPG”). 
  
 Industrial market 
  
 The industrial market comprises sales to high-volume, industrial users. In
the industrial market, natural gas competes with heavy and light fuel oils, propane and gas oil. 
  
 Marketing and Sales 
  
 The Group’s Marketing and Sales business includes the marketing of natural gas in the deregulated market, as well as the sale of products and services for the home and small businesses. Gas Natural Comercializadora and Gas Natural
Servicios are responsible for these activities in the industrial and domestic-business markets, respectively. 
  
 Gas sales in the liberalised Spanish market rose to 192,574 GWh for the year ended 31 December 2004, an increase of 11.3% with respect to the year
ended 31 December 2003. Of these sales, 27,892 GWh were for combined-cycle electricity generation, 40% of which were for Group combined-cycles.

electricity in the liberalized market in Spain. Gas Natural Electricidad is responsible for the generation and buying and selling of electricity; Gas Natural Comercializadora and Gas Natural Servicios are responsible for sales and marketing in the
liberalised market; and La Energía deals principally with cogeneration. 
  
 Since full liberalisation of Spain’s gas and electricity markets on 1 January 2003, the Group has promoted gas and electricity supply to the residential market. 
  
 In 2004, gas sales in the liberalised market reached 4,457 GWh, an increase
of 47.4%, including sales in the liberalised residential market to over 200,000 electricity customers. 
  
 At 31 December 2004, Gas Natural Comercializadora had a share of approximately 6% of the liberalised electricity market. 
  
 The power generated and largely sold to the wholesale market in 2004 totalled
5,802 GWh, an increase of 43.5% with respect to the previous year. 
  
 Electricity generation combined cycles rose to 5,672 GWh. This power, measured in busbars represented a coverage ratio of the electricity sold by the Group of 119%. The percentage of equivalent hours operating at full load exceeded 83% in
2004. 
  

 81 

 Gas Natural has 1,600 MW of operational combined cycle power production capacity, another 2,000 MW under
construction (1,200 MW at Cartagena and 800 MW at Plana del Vent), and 1,200 MW pending the granting of the relevant permits (including the Malaga and Barcelona projects). 
  
 In April 2005, Gas Natural paid €272 million for 100% of the shares of Desarrollo de Energías Renovables
(DERSA). DERSA has facilities in seven of Spain’s autonomous regions, which total 470 MW (228 MW attributable) of wind plants in operation and 1,228 MW (1,051 MW attributable) in projects under development. 
  
 Gas Natural had over 600 MW of wind capacity in operation and over 1,200 MW
under development and a presence in nine autonomous regions: Cataluña, Aragón, Navarra, La Rioja, Cantabria, Galicia, Andalucía, Castilla y León and Castilla-La Mancha. 
  
 The move to wind power complements Gas Natural’s decision in 1999 to
commence power generation by developing combined cycle plants. In addition, Gas Natural is developing other generation projects based on cogeneration technology through the group company, La Energía, S.A. 
  
 On 21 January 2005, the Cabinet approved the final individual assignment
of greenhouse gas emission rights for 2005-2007; Gas Natural was assigned 14.12 Mtonne of CO2. 
  
 Gas trading and transportation 
  
 This business includes gas supplies for wholesale outside Spain, ocean transport management and operation of the Maghreb-Europe gas pipeline (which began operations on 1 November 1996). 
  
 The Group carries out these activities through Gas Natural Aprovisionamientos
and Sagane. Sagane [mainly participates in] Metragaz, and is responsible for operating the Moroccan branch of the Magreb-Europe gas pipeline. 
  
 International natural gas supplies rose to 36,033 GWh in 2004, an increase of 20.4% over 2003. 89.1% of gas sales were made to the Latin American market,
based on medium-term contracts and the rest were spot operations in the international markets. 
  
 In 2004, the total volume of gas transport activity in Morocco, via EMPL and Metragaz was 115,637 GWh, a growth of 13.6% with respect to 2003. Of this figure, 87,386 GWh was transported for the Group via Sagane, and
28,251 GWh for the Portuguese company, Transgas. 
  
 The
enlargement of the capacity of the Maghreb-Europe gas pipeline to 136,000 GWh was completed and has been in operation since January 2005, enabling the transport of gas under the new supply contract with Algeria. 
  
 The Maghreb-Europe pipeline links the Hassi R’Mel gas fields in Algeria
with the transmission network of Enagás and is an important component in Gas Natural’s strategy of supply source diversification. The pipeline has a total length of 1,390 Km, consisting of 530 Km in Algeria, 540 Km in Morocco, 45 Km of
underwater pipelines beneath the Straits of Gibraltar and 275 Km in Spain from the coast at Tarifa to Cordoba. 
  
 International 
  
 The
Group is currently present in five countries in Latin America: Argentina, through the distributor Gas Natural BAN; Colombia, through Gas Natural ESP; Brazil, through CEG, CEG Rio and Gas Natural SPS; Mexico, where it operates with Gas Natural
México; and Puerto Rico (US), where it manages Ecoeléctrica. 
  
 Gas business sales in Latin America, which covers gas sales and third party access to the network (TPA) totalled 155,346 GWh in 2004, an increase of 10.2% with respect to 2003. In 2004, there was an increase of 10.8%
in gas sales, mainly due to the strong increase in salesof power generation in Brazil, despite residential sales being affected by the higher winter temperatures in Argentina. During 2004, the consolidation of the natural gas market for the
automotive sector continued, recording an average growth of almost 16%. 
  
 During 2004, the distribution network increased by 2,916 kilometres and as of 31 December 2004 reached 54,120 kilometres, an interannual growth of almost 6%. 
  
 Gas distribution customers, totalled 4,505,000 at 31 December 2004. The Group gained 280,000 new customers in 2004.

  

 82 

 Argentina 
  
 This division mainly involves gas distribution in Argentina through Gas Natural BAN. 
  
 The Group supplies natural gas and TPA services to the area of Buenos Aires Norte. 
  
 Gas Natural BAN is currently 50.4% owned by Gas Natural. 
  
 Brazil 
  
 Gas Natural is present in Brazil through: Compañía Distribuidora de Gas do Rio de Janeiro (“CEG”),
54.2% owned by Gas Natural, and CEG Rio, S.A.(“CEG Rio”), 59.6% owned by Gas Natural, (which are distributors in Rio de Janeiro and its metropolitan area); and Gas Natural SPS created in April 2000, which became a wholly-owned subsidiary
of the Group, after obtaining the concession for the distribution of gas in the southern area of Sao Paulo. 
  
 On 16 July 2004, Gas Natural acquired Enron’s stakes in CEG and CEG Rio, thus increasing its stake in those companies to 54.2% and 72.0%,
respectively. These companies were fully consolidated as of 1 July 2004. 
  
 In July 2005, Petrobras exercised a call option in respect of 12.4% of the shares of CEG Rio. 
  
 Colombia 
  
 Gas Natural E.S.P., (the gas distributor in Santa Fe de Bogotá, the Department of Santander and in the Altiplano Cundiboyacense), is currently 59%
owned by Gas Natural. 
  
 México 
  
 The Group owns 87% of all distributors of natural gas for Mexico Distrito
Federal and the areas of Nuevo Laredo, Saltillo, Toluca, Monterrey Estado de Guanajato, Bajío Norte that include the states of Aguascalientes, San Luis Potosí and Zatapecas. 
  
 Puerto Rico 
  
 On 30 October 2003, Gas Natural completed the acquisition of Enron’s assets in Ecoeléctrica, which comprised a 540MW combined cycle plant
and a 115,000m3 regasification plant, both of which came into service in 2000. The acquisition includes an exclusive regasification contract. 
  
 Europe 
  
 This section refers to gas supply and distribution in Italy and France. 
  
 Italy 
  
 The Group distributes and markets natural gas in Italy. 
  
 In 2004, the Group acquired Brancato (1Q), Smedigas and Nettis (3Q). Prior to these acquisitions the Group supplied gas in Italy through Gas Natural
Vendita. 
  
 The Group markets and distributes gas in Italy
through Gas Natural Vendita and Gas Natural Distribuzione, respectively. In 2004 this business in Italy euros 31.4 million to the Group’s ebitda, 2.3% of the total, and included non-recurrent and high margin operations carried out during
the first quarter of the year. 
  
 Gas sales in the liberalised
and regulated Italian markets in 2004 totalled 9,827 GWh while distribution services (TPA) totalled 40 GWh. 
  
 During 2004, the Group acquired Grupo Brancato during the first quarter and Grupo Smedigas and Grupo Nettis during the third quarter. These acquisitions
enabled the Group to broaden its customer base in Italy, which reached 252,000, at 31 December 2004. The gas distribution network exceeded 3,500 kilometres at 31 December 2004. 
  
 In 2004, the Group applied for administrative authorisation to build two regasification plants in Italy. The aim of these
projects is to secure a means of introducing natural gas in Italy. The projects submitted by the Group would be located in Trieste, in the north and in Taranto, in the south of the Italian peninsula. Both projects are of similar characteristics and
would consist of two 150,000m3 tanks, with an annual regasification capacity of 8 bcm. 
  

 83 

 France 
  
 In 2005 the Group has commenced activities in France via Gas Natural Commercialisation, a company which operates in the liberalised natural gas market, to
take advantage of the liberalisation of this country’s energy market which commenced in January 2005. 
  
 Legislation in Spain 
  
 The New Gas Act 34/1998 as amended by the Royal Decree-Law 6/2000 (the “Act”) liberalised the natural gas market in accordance with applicable European directives. The new regulation establishes freedom of gas sales between
marketers and eligible consumers and a transitional regime of maximum prices for non-eligible consumers. Since 1 January 2003 all customers that are considered eligible, have the right to move to the non regulated market. 
  
 The Act requires Gas Natural to grant third party access (“TPA”) to
the pipeline necessary to supply eligible consumers. Access is granted in exchange for payments of fees to Gas Natural which are intended to provide an adequate rate of return on the investments incurred. TPA is regulated under the Royal Decree
949/2001 and the Order of 15 February 2002, which states certain grounds for denying access, such as endangering the service provided by the network, causing Enagás not to fulfil its “take-or-pay” obligations, or the absence of
reciprocity in the third party’s country of origin. 
  
 The
Act appoints Enagás as “Technical Manager of the gas system” and no Enagás shareholder may hold more than 5 per cent of the voting shares of Enagás by 31 December 2006 (amended by the Law 62/2003 of 30
December). 
  
 The Act states that the gas supplied currently by
Algeria through the Maghreb-Europe pipeline will be assigned preferentially to Enagás for supply to the regulated market. 
  
 Since 1 January 2003 a company (or more than one company from the same group) may only supply up to 70 per cent of gas consumption in Spain,
excluding gas consumed by that same group. 
  
 Regulated remuneration

  
 On 31 January 2005, in line with the framework
approved in February 2002 Ministerial Order ITC 102/2005 (“the Order”) was published, updating the remuneration for 2005 for regulated gas activities in Spain. 
  
 The Order assigns euro 996.0 million to the Group as remuneration for distribution in 2005, i.e. a 7.4% increase on
2004. This increase is due to projected growth in the Group’s activity in 2005, the regulator’s projection of the average inflation (IPH), and the fact that the efficiency factors remained unchanged. 
  
 The Order also regulated a specific remuneration system in distribution for
installations providing access to new population centres so as to ensure that gas supplies to these areas are economically viable. This remuneration is limited to one year and is dependent on proof that the related installations have been brought
into service. The amount of remuneration under this heading in 2005 has yet to be published. 
  
 The estimated amount of remuneration for regulated-rate supply in 2005 will be approximately 20% lower than in 2004 because (i) the number of residential customers expected to migrate to the liberalised market
exceeds the projected number of new regulated-rate customers; and (ii) the regulation also recognises a smaller amount of losses in the network at pressures under 4 bar, (which was cut from 2% to 1%). 
  
 With regard to secondary transportation, the historical remuneration has been
updated in line with 85% of the IPH, to €16.6 million. 
  
 The revenue for distribution in subsequent years will be obtained by updating the previous year’s figures for inflation subject to a 0.85 efficiency factor, and the growth in business (increase in customers and sales), affected by a
0.71 efficiency factor. 
  
 Research and Development 
  
 Gas Natural engages in research and development both independently and in
collaboration with other Spanish and international companies and bodies. 
  

 84 

 Gas Natural’s research and development focuses mainly on safety in the transportation of natural gas
and on ways of reducing its impact on the environment, the development of new technologies in the distribution of gas and the development of new applications for natural gas. 
  
 Environmental matters 
  
 Relative to other fuels, natural gas has a low environmental impact. It does not generate ash or solid waste or other by-products in its phases of
production. Unlike fossil fuels such as coal or petroleum derivatives, no sulphur oxides or solid particles are produced. Natural gas is free from any volatile organic compounds which pollute the atmosphere. The combustion of natural gas causes
relatively small emissions of natural nitrogen oxides as compared to other fuels. Carbon dioxide emissions through natural gas combustion are 40.0% to 50.0% lower than for coal and 25.0% to 30.0% lower than for fuel oil. 
  
 Since 2001, the Group has been involved in the Promotional Plan (whereby
buses in several Spanish cities run on compressed natural gas). 
  
 Insurance

  
 The Group maintains insurance, which provides cover
against a number of risks including property damage, fire, flood, third party liability and business interruption. 
  
 Employees 
  
 As at 31 December 2004 the Group had 6,697 employees.

 This information has been prepared in accordance with the following Spanish tax legislation in force at the date of this Base Prospectus: 
  

	 	(a)	of general application, Additional Provision two of Law 13/1985, of 25 May on investment ratios, own funds and information obligations of financial intermediaries, as amended
by Law 19/2003, of 4 July on legal rules governing foreign financial transactions and capital movements and various money laundering prevention measures, as well as Royal Decree 1778/2004, of 30 July establishing information obligations in

	 	(b)	for individuals with tax residency in Spain which are Individual Income Tax (IRPF) taxpayers, Royal Legislative Decree 3/2004, of 5 March promulgating the Consolidated Text of
the Individual Income Tax Law, and Royal Decree 1775/2004, of 30 July promulgating the Individual Income Tax Regulations, along with Law 19/1991, of 6 June on Wealth Tax and Law 29/1987, of 18 December on Inheritance and Gift Tax;

  

	 	(c)	for legal entities resident for tax purposes in Spain which are Corporation Tax taxpayers, Royal Legislative Decree 4/2004, of 5 March promulgating the Consolidated Text of the
Corporation Tax Law, Royal Decree 1777/2004, of 30 July promulgating the Corporation Tax Regulations, and Ministry Order of 22 December 1999; and 

  

	 	(d)	for individuals and entities who are not resident for tax purposes in Spain which are non-resident income tax taxpayers, Royal Legislative Decree 5/2004, of 5 March
promulgating the Consolidated Text of the Non-Resident Income Tax Law, and Royal Decree 1776/2004, of 30 July promulgating the Non-Resident Income Tax Regulations, along with Law 19/1991, of 6 June on Wealth Tax and Law 29/1987, of

such tax promulgated by Royal Legislative Decree 1/1993, of 24 September and exempt from Value Added Tax, in accordance with Law 37/ 1992, of 28 December regulating such tax. 
  

 88 

 1. Individuals with Tax Residency in Spain 
  

	1.1	Individual income tax (Impuesto sobre la Renta de las Personas Físicas) 

  
 Both interest periodically received and income deriving from the transfer, redemption or repayment of the Notes constitute a
return on investment obtained from the transfer of own capital to third parties in accordance with the provisions of Section 23.2 of the Individual Income Tax Law, and must be included in the general portion of the investor’s taxable
income. 
  
 Both types of income are subject to a withholding on
account at the rate of 15 per cent. 
  
 If the period during
which such income is generated exceeds two years a reduction of 40 per cent. will be applied, for the effect of both withholdings and inclusion in taxable income. 
  

	1.2	Wealth tax (Impuesto sobre el Patrimonio) 

  
 Individuals with tax residency in Spain under an obligation to pay Wealth Tax must take into account the amount of the Notes which they hold as at
31 December in each year, when calculating their wealth tax liabilities. 
  

	1.3	Inheritance and Gift tax (Impuesto sobre Sucesiones y Donaciones) 

  
 Individuals with tax residency in Spain who acquire ownership or other rights over any Notes by inheritance, gift or legacy
will be subject to inheritance and gift tax in accordance with the applicable regional or State rules. 
  
 2. Legal Entities with Tax Residency in Spain 
  

	2.1	Corporation tax (Impuesto sobre Sociedades) 

  
 Both interest periodically received and income deriving from the transfer, redemption or repayment of the Notes constitute a return on investments for tax
purposes obtained from the transfer to third parties of own capital and must be included in the profit and taxable income of legal entities with tax residency in Spain for corporation tax purposes in accordance with the rules for this tax.

  
 In accordance with Section 59.s) of the Corporation Tax
Regulations there is no obligation to make a withholding on income obtained by Spanish Corporation Tax taxpayers (which for the sake of clarity, include Spanish tax resident investment funds and Spanish tax resident pension funds) from financial
assets traded on organised markets in OECD countries. The Directorate General for Taxation (Dirección General de Tributos – “DGT”), on 27 July 2004, issued a reply to a consultation indicating that in the case of
issues made by entities resident in Spain, such as Gas Natural Capital Markets, S.A., in order to comply with such exemption the Notes shall have been placed outside Spain in another OECD country. So long as the Notes are placed outside Spain, Gas
Natural Capital Markets, S.A. will not make any withholding on interest payments to Spanish Corporation Tax taxpayers that submit the relevant details in accordance with “Disclosure of Noteholder Information in connection with Interest
Payments” below. However, if the Spanish tax authorities determine that the Notes have been placed in Spain, Gas Natural Capital Markets, S.A. will be bound by such determination and with immediate effect shall make the relevant withholding on
payments under the Notes and, in accordance with Condition 10 (Taxation) no additional amounts will be payable. 
  
 In order to implement the exemption from withholding, the procedures set out in the Order of 22 December 1999 will be followed. No reduction will be
applied. (See “Disclosure of Noteholder Information in Connection with Interest Payments” below). 
  

	2.2	Wealth tax (Impuesto sobre el Patrimonio) 

  
 Legal entities are not subject to wealth tax. 
  

	2.3	Inheritance and Gift Tax (Impuesto sobre Sucesiones y Donaciones) 

  
 Legal entities with tax residency in Spain which acquire ownership or other rights over the Notes by inheritance, gift or
legacy are not subject to Inheritance and Gift Tax and must include the market value of the Notes in their taxable income for Spanish Corporation Tax purposes. 
  

 89 

 3. Individuals and Legal Entities with no Tax Residency in Spain 
  

	3.1	Non-resident income tax (Impuesto sobre la Renta de no Residentes) 

  

	(a)	With permanent establishment in Spain 

  
 Ownership of the Notes by investors who are not resident for tax purposes in Spain will not in itself create the existence of a permanent establishment in
Spain. 
  
 If the Notes form part of the assets of a permanent
establishment in Spain of a person or legal entity who is not resident in Spain for tax purposes, the legal rules applicable to income deriving from such Notes are the same as those previously set out for Spanish Corporation Tax taxpayers.

  

	(b)	With no permanent establishment in Spain 

  
 Both interest payments periodically received and income deriving from the transfer, redemption or repayment of the Notes, obtained by individuals or
entities who have no tax residency in Spain, being Non-Resident Income Tax taxpayers with no permanent establishment in Spain, are exempt from such Non-Resident Income Tax on the same terms laid down for income from Public Debt. This exemption is
not applicable if such income is obtained through countries or territories classified as tax havens (being those included in Royal Decree 1080/1991, of 5 July), in which case such income will be subject to Non-Resident Income Tax in Spain at the
rate of 15 per cent. which Gas Natural Capital Markets, S.A. will withhold. 
  
 For the purposes of applying the aforementioned exemption from Non-Resident Income Tax, it is necessary to comply with certain information obligations relating to the identity of the Noteholders, in the manner
detailed under “Disclosure of Noteholder Information in Connection with Interest Payments” as laid down in section 12 of Royal Decree 2281/1998, as amended by Royal Decree 1778/2004. If these information obligations are not complied with
in the manner indicated Gas Natural Capital Markets, S.A. will apply a withholding of 15 per cent. and Gas Natural Capital Markets, S.A. will not, as a result, be under any obligations to pay additional amounts. 
  

	3.2	Wealth tax (Impuesto sobre el Patrimonio) 

  
 To the extent that income deriving from the Notes is exempt from Non-Resident Income Tax, individuals who do not have tax residency in Spain who hold such
Notes will be exempt from Wealth Tax. 
  
 Furthermore, individuals
resident in a country with which Spain has entered into a double tax treaty in relation to Wealth Tax will generally not be subject to Wealth Tax. 
  
 If the provisions of the foregoing two paragraphs do not apply, individuals who are not tax residents in Spain will be subject to Wealth Tax to the extent
that rights deriving from the Notes can be exercised in Spanish territory. 
  
 Non-resident legal entities are not subject to Wealth Tax. 
  

	3.3	Inheritance and Gift tax (Impuesto sobre Sucesiones y Donaciones) 

  
 Individuals who do not have tax residency in Spain who acquire ownership or other rights over the Notes by inheritance, gift
or legacy, and who reside in a country with which Spain has entered into a double tax treaty in relation to Inheritance and Gift Tax will be subject to the relevant double tax treaty. 
  
 If the provisions of the foregoing paragraph do not apply, such individuals will be subject to Inheritance and Gift Tax in
accordance with the applicable regional and state legislation. 
  
 Non-resident entities which acquire ownership or other rights over the Notes by inheritance, gift or legacy are not subject to nheritance and Gift Tax. They will be subject to Non-Resident Income Tax. If the entity is resident in a country
with which Spain has entered into a double tax treaty, the provisions of the treaty will apply. In general, treaties provide for the taxation of this type of income in the country of residence of the beneficiary.

 4. Tax Havens 
  
 Pursuant to Royal Decree 1080/1991, of 5 July the following are each considered to be a tax haven: 
  

					
	Principality of Andorra,	  	Channel Islands (Jersey and	  	Hashemite Kingdom of Jordan,
	Netherlands Antilles,	  	Guernsey),	  	Republic of Lebanon,
	Aruba,	  	Jamaica,	  	Republic of Liberia,
	Kingdom of Bahrain,	  	Republic of Malta,	  	Principality of Liechtenstein,
	Sultanate of Brunei,	  	Falkland Islands,	  	Grand Duchy of Luxembourg

	United Arab Emirates,	  	Marianas Islands,	  	received by the Companies
	Gibraltar,	  	Mauritius,	  	referred to in paragraph 1 of
	Hong-Kong,	  	Montserrat,	  	Protocol annexed Avoidance of
	The Island of Anguila,	  	Republic of Nauru,	  	Double Taxation Treaty, dated

	Grenada,	  	British Virgin Islands,	  	Republic of Singapore.
	Fiji Islands,	  	Virgin Islands (of the United States),	  	 

  
 If the aforementioned
countries and territories enter with Spain into an agreement for the exchange of information on tax matters or into a double taxation treaty which contains an exchange of information clause, they will no longer be regarded as a tax haven for Spanish
tax purposes as from the entry into force of such agreements/treaties. 
  
 Taxation in Spain – Payments under the Guarantee 
  
 On the basis that payments of principal and interest made by the Guarantor under the Deed of Guarantee should be characterised as an indemnity under Spanish law, such payments may be made free of withholding or deduction on account of any
Spanish tax. 
  
 However, although there is no precedent or
regulation on the matter, if the Spanish tax authorities take the view that the Guarantor has effectively assumed the obligations of the relevant Issuer under the Notes (whether contractually or by any other means) the following tax consequences may
derive: 
  

	 	(a)	in the case of unlisted Notes issued by Gas Natural Finance B.V., the Spanish Tax Authorities may attempt to impose withholding tax in Spain on any payments made by the Guarantor in
respect of interest on the Notes, unless the recipient is resident for tax purposes in a Member State of the European Union other than Spain and not acting through a territory considered as a tax haven pursuant to Spanish Law (currently as set out
in Royal Decree 1080/1991, of 5 July) nor through a permanent establishment in Spain or in a country outside the European Union, provided that such recipients provide to the Guarantor a tax residence certificate duly issued by the tax authorities of
the relevant country, each certificate being valid for a period of one year from the date of issue under Spanish law and therefore new certificates needing to be issued periodically; and 

  

	 	(b)	in the case of listed Notes issued by Gas Natural Finance B.V. and Notes issued by Gas Natural Capital Markets, S.A., the Spanish Tax Authorities may determine that payments made by
the Guarantor, relating to interest on the Notes, will be subject to the same tax rules set out above for payments made by Gas Natural Capital Markets, S.A. 

  
 Taxation in Spain – Disclosure of Noteholder Information in Connection with Interest Payments 
  
 The clearing systems are currently in discussions to harmonise the
procedure for the provision of information as required by Spanish laws and regulations. The following is a summary only and is subject to the outcome of the clearing systems’ discussions as well as to further clarification from the Spanish tax
authorities regarding such laws and regulations. Noteholders must seek their own advice to ensure that they comply with all procedures to ensure correct tax treatment of their Notes. None of the Issuers, the Guarantor, the Arranger, the Dealers, the

  

 91 

 Paying Agents or the clearing systems assume any responsibility therefor. Unlisted Notes issued by Gas Natural
Finance B.V. will not be subject to the reporting requirements established pursuant to the above legislation. 
  
 1. Legal Entities with tax residency in Spain subject to Spanish Corporation tax and permanent establishments in Spain of non-residents entities. 
  
 In the case of Notes issued by Gas Natural Capital Markets, S.A. and, in
accordance with procedures established in the Agency Agreement, the Agent must receive a list of those Noteholders that are Spanish Corporation Tax taxpayers specifying the name, address, Tax Identification Number, ISIN code of the Notes, number of
Notes held at each interest payment date, gross income and amount withheld, substantially in the form set out below. (See Annex III A below). 
  
 2. Individuals with tax residency in Spain 
  
 In the case of listed Notes issued by Gas Natural Capital Markets, S.A. and, in accordance with procedures established in the Agency Agreement, the Agent
must receive a list of those Noteholders that are Spanish resident individuals specifying the name, address, Tax Identification Number, ISIN code of the Notes, number of Notes held at each interest payment date, gross income and amount withheld,
substantially in the form set out below (See Annex III B below). 
  
 3.
Individuals and Legal Entities with no tax residency in Spain 
  
 The information obligations to be complied with in order to apply the exemption in connection with interest payments payable with Notes issued by Gas Natural Capital Markets, S.A. are those laid down in Section 12 of Royal Decree
2281/1998 (“Section 12”), as amended by Royal Decree 1778/2004, being the following: 
  
 In accordance with sub-section 1 of such Section 12, a return must be made to the Spanish tax authorities specifying the following information with
respect to the Notes: 
  

	 	(a)	the identity and country of residence of the recipient of the income. When the income is received on behalf of a third party, the identity and country of residence of that third
party; 

  

	 	(b)	the amount of income received; and 

  

	 	(c)	details of the Notes. 

  
 In accordance with sub-section 1 of such Section 12, for the purpose of preparing the return referred to in sub-section 3 of Section 12, the
following documentation must be obtained on each payment of income evidencing the identity and residency of each Noteholder: 
  

	 	(a)	if the non-resident Noteholder acts on its own account and is a central bank, other public institution or international organisation, a bank or credit institution or a financial
entity, including collective investment institutions, pension funds and insurance entities, resident in an OECD country or in a country with which Spain has entered into a double tax treaty subject to a specific administrative registration or
supervision scheme, the entity in question must certify its name and tax residency in the manner laid down in Annex I of the Order of 16 September 1991, promulgated pursuant to Royal Decree 1285/1991 (See Annex I below), of 2 August
establishing the procedure for the payment of interest on Book Entry State Debt (as defined therein) to non-residents who invest in Spain without the intervention of a permanent establishment; 

  

	 	(b)	in the case of transactions in which any of the entities indicated in the foregoing paragraph (a) acts as intermediary, the entity in question must, in accordance with the
information contained in its own records, certify the name and tax residency of each Noteholder in the manner laid down in Annex II of the Order of 16 September 1991 (See Annex II below); 

  

	 	(c)	 in the case of transactions which are channelled through a securities clearing and deposit entity recognised for these purposes by Spanish law or by that of another
OECD member country, the entity in question must, in accordance with the information 

  

 92 

	 	 
contained in its own records, certify the name and tax residency of each Noteholder in the manner laid down in Annex II of the Order of 16 September
1991 (See Annex II below); 

  

	 	(d)	in other cases, residency must be evidenced by submission of the residency certificate issued by the tax authorities of the State of residency of the holder. These certificates will
be valid for one year as from the date of issue. 

  
 In the case of Notes issued by Gas Natural Capital Markets, S.A. and in accordance with subsection 4 of Section 12, for the purpose of implementing the exemption provided for, the following procedure must be followed: on each interest
payment date Gas Natural Capital Markets, S.A. must transfer the net amount to the entities referred to in paragraph a), b) and c) resulting from applying the general withholding rate (currently 15 per cent.) to the gross interest. If the
certificates referred to are received prior to expiry of the payment period, Gas Natural Capital Markets, S.A. will pay the amounts withheld to the extent that the certificates provide the required information. 
  
 In order for a beneficial owner to benefit from an exemption from
withholding, the above documentation should be received by the Agent in accordance with the procedures established in the Agency Agreement, which may be inspected during normal business hours at the specified office of the Agent. 
  
 If the Agent does not receive complete documentation in respect of an
eligible Noteholder by the specified deadline, such Noteholder may obtain a quick refund of the full amount of withholding tax so withheld by ensuring that the documentation described above is received by the Agent no later than 10.00 a.m. (CET) on
the tenth calendar day of the month following the relevant interest payment date (or if such date is not a Business Day, the Business Day immediately preceding such date) (the “Quick Refund Deadline”). 
  
 Holders entitled to a refund but in respect of whom relevant documentation is
not received by the Agent on or before a Quick Refund Deadline may seek a full refund of withholding tax directly with the Spanish tax authorities. 
  
 Annexes I, II, IIIA and IIIB are set out below. 
  
 EU Savings Tax Directive 
  
 Under EC Council Directive 2003/48/EC on the taxation of savings income, each Member State is required, from 1 July 2005, to provide to the tax
authorities of another Member State details of payments of interest or other similar income paid by a person within its jurisdiction to, or collected by such a person for, an individual resident in that other Member State; however, for a
transitional period, Austria, Belgium and Luxembourg may instead apply a withholding system in relation to such payments, deducting tax at rates rising over time to 35%. The transitional period is to terminate at the end of the first full fiscal
year following agreement by certain non-EU countries to the exchange of information relating to such payments. 
  
 Also with effect from 1 July 2005, a number of non-EU countries, and certain dependent or associated territories of certain Member States, have
agreed to adopt similar measures (either provision of information or transitional withholding) in relation to payments made by a person within its jurisdiction to, or collected by such a person for, an individual resident in a Member State. In
addition, the Member States have entered into reciprocal provision of information or transitional withholding arrangements with certain of those dependent or associated territories in relation to payments made by a person in a Member State to, or
collected by such a person for, an individual resident in one of those territories.

 SUBSCRIPTION AND SALE 
  
 The Permanent Dealers have in an amended and restated programme agreement dated 17 November 2005 (the “Programme
Agreement”) agreed with each Issuer and the Guarantor a basis upon which they or any of them may from time to time agree to purchase Notes. Any such agreement will extend to those matters stated under “Form of the Notes”, “Form
of Final Terms” and “Terms and Conditions of Notes issued by Gas Natural Finance B.V.” and “Terms and Conditions of Notes issued by Gas Natural Capital Markets, S.A.” above. However, each Issuer has reserved the right to
sell Notes directly on its own behalf to Dealers that are not Permanent Dealers. The Notes may be resold at prevailing market prices, or at prices related thereto, at the time of such resale, as determined by the relevant Dealer. The Notes may also
be sold by each Issuer through the Dealers, acting as agents of the relevant Issuer. The Programme Agreement also provides for Notes to be issued in syndicated Tranches that are jointly and severally underwritten by two or more Dealers. 

 
 The relevant Issuer will pay each relevant Dealer a commission in respect
of Notes subscribed by it as separately agreed between them. Each Issuer has agreed to reimburse the Arranger for certain of its expenses incurred in connection with the establishment of the Programme. The commissions payable in respect of an issue
of Notes on a syndicated basis will be stated in the applicable Final Terms. 
  
 Each of the Issuers and the Guarantor has agreed to indemnify the Dealers against certain liabilities in connection with the offer and sale of the Notes. The Programme Agreement entitles the Dealers to terminate any
agreement that they make to subscribe Notes in certain circumstances prior to payment for such Notes being made to the relevant Issuer. 
  
 United States 
  
 The Notes have not been and will not be registered under the Securities Act and may not be offered, sold within the United States or to, or for the
account or benefit of, U.S. persons except in certain transactions exempt from the registration requirements of the Securities Act. 
  
 Each Dealer has represented and agreed and each further Dealer appointed under the Programme will be required to represent and agree that, except as
permitted by the Programme Agreement, it will not offer, sell or deliver Notes (i) as part of their distribution at any time and (ii) otherwise until 40 days after the completion of the distribution of all the Notes of the Tranche of which
such Notes are a part within the United States or to, or for the account or benefit of, U.S. persons and it will have sent to each dealer to which it sells Notes during the distribution compliance period a confirmation or other notice setting forth
the restrictions on offers and sales of the Notes within the United States or to, or for the account or benefit of, U.S. persons. Terms used in the preceding paragraphs and in this paragraph have the meanings given to them by Regulation S under the
Securities Act. 
  
 In addition, until 40 days after the
completion of the distribution of all Notes of the Tranche of which such Notes are a part, on offer or sale of Notes within the United States by any dealer (whether or not participating in the offering) may violate the registration requirements of
the Securities Act. 
  
 The Notes are subject to U.S. tax law
requirements and may not be offered, sold or delivered within the United States or its possessions or to a United States person, except in certain transactions permitted by U.S. tax regulations. Terms used in this paragraph have the meanings given
to them by the U.S. Internal Revenue Code and regulations thereunder. 
  
 Each issue of Index Linked Notes and Dual Currency Notes shall be subject to such additional U.S. selling restrictions as the relevant Issuer and the relevant Dealer or Dealers shall agree as a term of the issue and purchase of such Notes,
which additional selling restrictions shall be set out in the applicable Final Terms. Each relevant Dealer has agreed and each further Dealer appointed under the Programme will be required to agree that it will offer, sell or deliver such Notes only
in compliance with such additional U.S. selling restrictions. 
  
 European
Economic Area 
  
 In relation to each Member State of the
European Economic Area which has implemented the Prospectus Directive (each, a “Relevant Member State”), each Permanent Dealer has represented and agreed, and each further Dealer appointed under the programme will be required to represent

  

 98 

 and agree, that with effect from and including the date on which the Prospectus Directive is implemented in that Relevant
Member State (the “Relevant Implementation Date”) it has not made and will not make an offer of Notes to the public in that Relevant Member State prior to the publication of a prospectus in relation to the Notes which has been approved by
the competent authority in that Relevant Member State or, where appropriate, approved in another Relevant Member State and notified to the competent authority in that Relevant Member State, all in accordance with the Prospectus Directive, except
that it may, with effect from and including the Relevant Implementation Date, make an offer of Notes to the public in that Relevant Member State at any time:

	 	(c)	in any other circumstances which do not require the publication by the relevant Issuer of a prospectus pursuant to Article 3 of the Prospectus Directive. 

 
 For the purposes of this provision, the expression an “offer of Notes
to the public” in relation to any Notes in any Relevant Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Notes to be offered so as to enable an investor to decide to
purchase or subscribe the Notes, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression “Prospectus Directive” means Directive 2003/71/EC and includes any
relevant implementing measure in each Relevant Member State.

 Notes to the Financial Information of Gas Natural Capital Markets, S.A. at 31 October 2005 
  
 Note 1. General information 
  
 The objectives of the Company are to raise funds by issuing preference shares and other debt
financial instruments, in accordance with the Third Additional Requirement of the Law 19/2003 of 4 July, with the guarantee of Gas Natural SDG, S.A. 
  
 The registered office of the Company is Avda. Portal de  ́ lAngel 20-22, Barcelona, Spain. 
  
 Note 2. Basis of preparation 
  
 This financial information has
been prepared in accordance with International Financial Reporting Standards (“IFRS”) and interpretations of the International Financial Reporting Interpretations Committee (“IFRIC”) issued by the International Accounting
Standards Board. The financial information also applies IFRS 1, First-time Adoption of International Financial Reporting Standards (“IFRS 1”) as this financial information represents part of the period covered by the Company’s first
statutory financial statements being for the period from 23 May 2005 to 31 December 2005 and which will be the first statutory financial statements that will adopt IFRS, as adopted for use in the European Union. This financial information
does not constitute statutory financial statements. 
  
 IFRS 1 sets out the
procedures that the Company must follow when it adopts IFRS for the first time. Under IFRS 1 the Company is required to establish its IFRS accounting policies as at the balance sheet date to which its statutory financial statements have been drawn
up and, in general, apply those policies retrospectively to determine the IFRS opening balance sheet at its date of transition. In the case of the Company the date for establishing its IFRS accounting policies will be31December 2005 and its date of
transition is 23 May 2005, being its date of incorporation. Accordingly, the 31 December 2005 statutory financial statements will be the first statutory financial statements prepared by the Company in accordance with accounting standards
as adopted for use in the European Union. As such the 31 December 2005 statutory financial statements will take account of the extant requirements and options in IFRS, as adopted for use in the European Union, as they relate to those statutory
financial statements at that date. 
  
 For the purposes of this financial
information the Directors have used accounting policies as at 31 October 2005, being the date of the closing balance sheet in this financial information. Accordingly, this financial information has been prepared in accordance with those IFRS
standards and IFRIC interpretations issued and effective or issued and early adopted as at the time of preparing this financial information and which the Company expects to apply in its first statutory financial statements under IFRS, as adopted for
use in the European Union, for the period ended 31 December 2005. The IFRS standards and IFRIC interpretations that will be applicable at 31 December 2005, including those that will be applicable on an optional basis, are not known with
certainty at the time of preparing this financial information. 
  
 IFRS 1 provides
a number of optional exemptions to the general principle of retrospective application. At 31 October 2005 none of these exemptions are applicable to the Company. As the Company is a newly incorporated company and has not to date produced any
financial statements no reconciliation from Spanish GAAP to IFRS has been presented. 
  
 This financial information has been prepared under the historical cost convention. 
  
 The preparation of financial information in conformity with generally accepted accounting
principles requires the use of estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial information and the reported amounts of revenues and expenses during the reporting period. Although
these estimates are based on management’s best knowledge of the amount, event or actions, actual results may differ from those estimates. 
  
 Note 3. Accounting policies 
  
 The most significant accounting policies applied by the group in the preparation of this financial information are as follow 
  

	a.	Trade and non-trade debtors and creditors. Payables and receivables originating from operations, whether or not arising from the normal course of trade, are recorded at their
nominal value and are classified as short term or long term depending on whether or not these become due within one year fiscal. 

  
 Provisions for potential bad debts are made as considered appropriate. 
  

 105 

 Credit lines are shown at the amount actually drawn down. 
  

	b.	Corporate income tax. Corporate income tax expense is calculated base don the profit for the year before tax, increased or reduced by the permanent differences and deducting the
allowances and deductions to which the Company is entitled. 

  
 The Company pay taxes in the Regime of Consolidated Declaration since the year ended 2005. 
  

	c.	Income and expenses. Income and expenses are recorded on an accruals basis, i.e. in the period in which the income or expense deriving from the goods or services in question is
earned or incurred rather than the period in which the cash is actually received or disbursed. 

  
 However, out of prudence, the Company only records the profit realized at the year end, insofar as the foreseeable risks and losses that may arise are
recorded as soon as they are known. 
  
 Note 4. Cash and cash equivalent

  
 Cash and cash equivalents includes the credit balance with banks.

  
 Note 5. Shareholder’s equity 
  
 The amount of shareholder’s equity at 31 October 2005 is as follow: 
  

							
	 	  	 Amount at
 1.1.05

listing on the Official List and to trading on the Gilt-Edged and Fixed Interest Market of the London Stock Exchange, dealings will be permitted by the Gilt-Edged and Fixed Interest Market of the London Stock Exchange in accordance with the rules of
the FSA. Transactions will normally be effected for delivery on the third working day in London after the day of the transaction. However, Notes may be issued by Gas Natural Finance B.V. pursuant to the Programme which will not be admitted to
listing, trading and/or quotation by the FSA and/or London Stock Exchange or any other listing authority, stock exchange and/or quotation system or which will be admitted to listing, trading and/or quotation by such listing authority, stock exchange
and/or quotation system as the relevant Issuer and relevant Dealer(s) may agree (subject, in the case of Gas Natural Capital Markets, S.A., to the publication of a supplemental prospectus in relation to such Notes).
