Stock Purchase Agreement  Sale of
PacifiCorp



On May 23, 2005, a Stock Purchase Agreement
was entered into between the Company, PacifiCorp Holdings, Inc. (PHI) and MidAmerican Energy Holdings Company (MidAmerican). Pursuant to the Stock Purchase Agreement, PHI has agreed to (and the Company has agreed to cause PHI
to) sell, and MidAmerican has agreed to buy, all of the common stock of PacifiCorp, subject to certain conditions (the Sale).



The total proceeds to be paid to PHI in consideration for the transfer of the common stock is to be satisfied



---

by a cash payment on closing of the Sale of US$5,109,500,000 plus an amount equal to the aggregate amount of capital contributions made by the Company to
PacifiCorp in respect of the financial year 2006/07. MidAmerican will assume net debt on closing, expected to be approximately US$4.3 billion. In addition, PHI has agreed to make annual payments of US$4.0 million to MidAmerican on each anniversary
of the date of closing for a period of twenty-five years in respect of certain non-regulated businesses currently reported as part of the PacifiCorp segment in the Companys group financial reports, which were not included in the Sale.



Closing of the Sale is subject to approval by holders of the
Companys ordinary shares and American depositary shares (the Shareholders). The Stock Purchase Agreement may be terminated by MidAmerican if the approval of the Shareholders is not received on or before September 1, 2005.



Closing of the Sale is also conditional on, among other
things:



| | (i) | all necessary final consents and approvals of, and filings with, the Department of Justice or the Federal Trade Commission, the Federal Energy Regulatory Commission, the Securities
and Exchange Commission, the Nuclear Regulatory Commission and the Federal Communications Commission and any other necessary governmental or regulatory authority having been obtained or made without a material adverse effect on PacifiCorp arising
therefrom;
| | --- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (ii) | all necessary final consents and approvals of, and filings with, the applicable state public utility commissions in Oregon, Utah, Washington, Wyoming, California and Idaho having
been obtained without terms or conditions that have a meaningful adverse effect on the business or prospects of PacifiCorp (unless MidAmerican otherwise approves), where meaningful adverse effect is deemed to be equivalent to a material
adverse effect on an entity otherwise identical to PacifiCorp but having only 25% of its business, properties, assets, liabilities, financial condition, revenues, net income, results of operations and prospects;
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | other necessary consents or approvals having been obtained (except where failure to obtain them would not have a material adverse effect on the ability of the parties, or any of
them, to consummate the Sale, PacifiCorp, or where MidAmerican elects not to require such consents to be obtained);
| | ----- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | no material adverse effect with respect to PacifiCorp and no facts or circumstances which would or reasonably could, when taken together with any breaches or violations of the
representations, warranties, covenants or agreements of the Company or PHI, result in a material adverse effect having occurred. For these purposes, certain general weather, economic or financial conditions shall not be taken into account;
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) | the representations and warranties of the parties to the Stock Purchase Agreement remaining true and correct in all respects, subject to certain provisions as to materiality and
certain other exceptions, as of the closing date or, in the case of representations and warranties made as of an earlier specified date, on such date;
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (vi) | the parties performing their covenants and obligations under the agreement in all material respects (other than in respect of the transfer of the common stock in PacifiCorp, which
shall be performed and complied with in all respects);
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (vii) | expiry or termination of any waiting period under antitrust legislation in the United States; and
| | ----- | -------------------------------------------------------------------------------------------------



| | (viii) | no competent court or governmental or regulatory authority having enacted or issued any law or order which prohibits or has the effect of prohibiting the Sale.
| | ------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------



Certain of the conditions may be waived by the
Company or by MidAmerican. If certain of the conditions are not fulfilled at closing, the Company may (but shall not be required to) make such payments to PacifiCorp to cure such breach, provided (in MidAmericans reasonable judgment) such
payment cures such breach.



Under the Stock Purchase
Agreement, the Company and PHI have agreed to invest additional cash capital contributions in PacifiCorp prior to closing. Pursuant to these arrangements, the Company has agreed to invest US$500 million during the 2005/06 financial year without
additional compensation from MidAmerican. In addition, the Company has agreed to make further investments during the 2006/07 financial year of up to US$525 million, contributed quarterly, although the Company will be fully compensated on closing for
any such payments made.



---

Under the terms of the Stock Purchase Agreement, the Company and PHI have agreed to cause PacifiCorp to
conduct its business in the ordinary course consistent with past business practice, including retaining the services of PacifiCorps key officers and employees. The Company and PHI have agreed to certain restrictions on the conduct of the
PacifiCorp business predominantly consistent with PacifiCorps business plan and budget prior to closing including (among other things) restrictions relating to capital expenditures, mergers, acquisitions, sales of assets, the incurrence or
guarantee of any indebtedness or the adoption, amendment or termination of any employee benefit plan and entry into contracts with members of the Scottish Power plc group, regulatory matters and the construction or acquisition of generating,
transmission or delivery capacity. A joint executive committee comprised of representatives of the Company and MidAmerican has been established with the objective of facilitating and achieving closing of the Sale and integration, strategy planning
and developing recommendations concerning the business operations of PacifiCorp prior to closing. Nothing in the Stock Purchase Agreement gives MidAmerican the right to control or direct PacifiCorps operations prior to closing, pending which
each of the Company, PHI and PacifiCorp shall exercise, consistent with the Stock Purchase Agreement, complete control and supervision over its operations.



The Company and PHI have also agreed that PacifiCorp and its subsidiaries will only pay dividends or make distributions prior to closing in a manner
consistent with an approved budget namely, the payment to the Company of US$215 million by way of dividend during the 2005/06 financial year, and US$242 million by way of dividend during the 2006/07 financial year, any such amounts to be payable
quarterly but if closing occurs during a quarter, the dividend in relation to that quarter to accrue pro rata on a daily basis.



Under the Stock Purchase Agreement, the Company has agreed that neither it nor any of its subsidiaries or affiliates nor their respective representatives
shall initiate, solicit or encourage any enquiries, proposal or offer with respect to PacifiCorp or engage in negotiations concerning, or provide any confidential information to any person relating to any such proposal. Prior to Shareholder
approval, the board of directors of the Company (Directors) may engage in negotiations concerning, or provide any confidential information to any person or group that makes an unsolicited bona fide alternative proposal for PacifiCorp
subject to certain additional conditions and if and only to the extent required by the Directors fiduciary duties. The Company and PHI have also agreed that for so long as the Stock Purchase Agreement remains in effect, neither of them will
enter any agreement with any person which provides for or in any way facilitates an alternative proposal regarding PacifiCorp.



Under the Stock Purchase Agreement, as of closing, companies in the retained Scottish Power plc group shall cease to be participating employers in the
PacifiCorp employee benefit plans. The Company has agreed to assume all liabilities accrued by present or former employees of the retained continuing group (or former employees of the Centralia businesses that were sold by PacifiCorp)
(Transferred Individuals) to the extent such liabilities have not already been funded by the Scottish Power plc group.



The Stock Purchase Agreement also provides for the transfer of various assets between the existing PacifiCorp employee benefit plans to new plans to be
established by the Company in respect of the Transferred Individuals.



The Company has agreed to establish a defined benefit pension plan for the Transferred Individuals and to transfer assets from the PacifiCorp retirement plan in the amount required by law in respect of the Transferred Individuals to the new
plan as soon as practicable after closing. The Company has also agreed to transfer in kind the accounts of the Transferred Individuals under PacifiCorps employee savings and stock ownership plan to a new group savings plan on or before
closing. On or prior to closing, the Company shall also cause the transfer in kind of an amount equal to the fair market value of the assets of the proportion of the funded accounts of the plans attributable to the Transferred Individuals from the
PacifiCorp post-retirement welfare plans to newly established plans.



The Stock Purchase Agreement may be terminated prior to closing, whether before or after Shareholder approval, in certain circumstances including:



| | (i) | by mutual agreement of the Company and MidAmerican;
| | --- | ---------------------------------------------------



---

| | (ii) | by a party if the Sale has not been completed by May 23, 2006 and the failure to complete was not caused by a breach of the representations, warranties and covenants of that party
in the Stock Purchase Agreement. If federal or state approvals have not been obtained by May 23, 2006, the term of the Stock Purchase Agreement may be extended to February 17, 2007 at the election of either the Company or MidAmerican, provided the
other conditions to closing have been fulfilled (or are capable of being fulfilled);
| | ---- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | by MidAmerican where the Shareholders do not approve the Sale on or before September 1, 2005 or by either party where the Shareholders do not approve the Sale on a vote actually
held at a Shareholder meeting;
| | ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iv) | by a party if there has been a material breach of the representations, warranties or covenants of the other party where the effect of such breaches in the aggregate would have a
material adverse effect on PacifiCorp or the ability of the parties to consummate the Sale;
| | ---- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (v) | by MidAmerican where the Board of the Company or PHI withdraws, adversely modifies, or fails to reaffirm, its recommendation of the Sale or shall have recommended or taken no
position with respect to an alternative proposal for PacifiCorp;
| | --- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (vi) | by either party where any competent court or governmental or regulatory authority has enacted or issued any law or final order which prohibits the Sale; and
| | ---- | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (vii) | in the further circumstances described in the final paragraph under break fee arrangements outlined below.
| | ----- | ------------------------------------------------------------------------------------------------------------



The Company and MidAmerican have agreed to certain break fee arrangements.
Under the Stock Purchase Agreement, the Company has agreed to pay MidAmerican a break fee of US$10 million if, prior to Shareholders approving the Sale, an alternative proposal relating to PacifiCorp or a proposal for the acquisition of control of
the Company is made or announced, is rejected by the Company, and the Shareholders do not subsequently approve the Sale at the relevant Shareholders meeting or, in any event, on or before September 1, 2005 and the agreement with MidAmerican is
terminated as a result.



If the break fee becomes payable (or
in the case of (a) below, would otherwise become payable), then its amount is increased to (a) US$100 million (in total) if the Companys Board instead of rejecting such proposal, recommends or takes no position with respect to it, withdraws,
adversely modifies or fails to reaffirm its recommendation of the Sale and (b) US$250 million (in total) if, within a year of the agreement with MidAmerican terminating, the Company enters into an agreement with respect to or consummates an
alternative proposal relating to PacifiCorp or any person announces a firm intention to make an offer to acquire control of the Company. The maximum aggregate amount that could be payable by the Company in break fees is US$250 million.



If the Stock Purchase Agreement is terminated as a result of Shareholders
not approving the Sale at the relevant Shareholders meeting or, in any event, by September 1, 2005, in circumstances where none of the break fees described above is payable, then the Company shall pay MidAmerican an amount equal to US$10
million.



A break fee of US$250 million is payable by
MidAmerican to the Company if the Company terminates the Agreement as a result of MidAmerican agreeing to or announcing a proposal to acquire certain competing utility and energy assets if the same directly or indirectly results in the failure to
satisfy certain regulatory conditions to the Sale and/or creates or imposes additional conditionality or costs which result in MidAmerican choosing not to complete or to terminate the Agreement.



Under the Stock Purchase Agreement, the Company and PHI have given, jointly
and severally, certain representations and warranties, including warranties of the type usual for a transaction of this nature, concerning their power and ability to enter into the agreement, details of the common stock that is the subject of the
Sale, regulatory and legal matters, liabilities and obligations, accounts and financial matters, taxation, pensions, employees, environmental matters, intellectual property matters, insurance, trading and the assets of PacifiCorp.



The Company has also given an indemnity in respect of certain matters
including losses arising from any breach or inaccuracy (whether or not material) of any of the representations or warranties or any failure to perform or



---

observe any term, covenant or provision of the agreement, and in relation to certain liabilities (i) not reflected in the Companys financial statements
or (ii) resulting from certain employee incentive arrangements or changes to the employee benefit plans. The liability of the Company under the indemnity is subject to the limitations set our below.



The liability of the Company for claims under the indemnity in respect of
breaches of covenants and certain representations and warranties is capped at 50% of the Sale price.



The liability of the Company for claims under the indemnity in respect of breach or inaccuracy of certain other representations and warranties (including
breaches of representations and warranties given in relation to the details of the common stock in PacifiCorp, the good standing and corporate power and authority of PacifiCorp and its subsidiaries to carry on their business and that certain events
have not occurred with respect to PacifiCorp) is unlimited.



Other than in respect of breaches of certain representations and warranties (including those referred to in the paragraph above), MidAmerican has agreed not to claim under the indemnity for breach of warranty unless the cumulative aggregate
amount of its losses exceeds US$50 million (in which case the Company shall be liable only for the amount of such losses in excess of US$25 million). Losses below US$10,000 shall be disregarded entirely other than in respect of breaches of certain
specified warranties, covenants and conditions.



MidAmerican
shall not be entitled to be indemnified for losses arising from breach or inaccuracy of the representations and warranties of the Company or PHI if such breach or inaccuracy resulted from (i) the effects of transactions expressly permitted under
certain pre-completion covenants or (ii) consent or approval of any governmental or regulatory authority, where the actions taken by PacifiCorp were approved by MidAmerican or the joint executive committee.



MidAmerican has agreed not to claim under the indemnity for losses arising
from breaches of any term, provision or covenant (other than in certain circumstances including breach of the pre-closing covenants relating to cash capital contributions and dividends outlined above) unless the cumulative aggregate amount of such
losses exceeds US$7.5 million.



The representations,
warranties and covenants given by the Company and PHI will last for one year from the date of closing, other than those given in respect of taxation (which survive for the applicable statutory periods), employee benefits and environmental matters
(which survive until the third anniversary of closing) and certain other specified matters (including the agreement for sale and purchase of the common stock in PacifiCorp, the good standing and corporate power and authority of PacifiCorp and its
subsidiaries to carry on their business, the pre-closing covenants relating to cash capital contributions and dividends outlined above and the employee benefits arrangements summarized above) and covenants or agreements which have been willfully
breached, each of which will survive indefinitely.



MidAmerican has given certain representations and warranties to the Company including warranties in respect of its authority to enter into the agreement and the sufficiency of its financing arrangements, which shall (other than in respect
of certain warranties) survive for one year from the date of closing. The Company has the benefit of an indemnity from MidAmerican in respect of losses arising from breach of these warranties and representations, subject to similar limitations to
