                           Forward-looking statement

     Certain forward-looking statements contained in this brochure are subject
to risks and uncertainties. Forward-looking statements include, but are not
limited to, information concerning possible or assumed future results of
operations of ScottishPower and PacifiCorp, as well as statements preceded by,
followed by or that include the words "believes", "expects", "estimates",
"intends", "anticipates" or similar expressions. You should understand that
certain important factors (in addition to those discussed in this brochure and
in the Proxy Statement/Prospectus) could affect the future results of
ScottishPower and PacifiCorp and could cause those results to differ materially
from those expressed in our forward-looking statements.

                                  Risk factors

     ScottishPower's business is subject to regulation in the U.K., a general
description of which is set forth in ScottishPower's Annual Report on Form 20F.
It is expected that regulation will continue to have a material bearing on the
profitability and investment capability of ScottishPower. ScottishPower's
regulated monopoly businesses comprise electricity transmission and distribution
in ScottishPower and electricity distribution in Manweb (together representing
44% of the 1999 operating profit) and the water supply and waste water business
in Southern Water (representing 33% of ScottishPower's 1999 operating profit).
The regulatory price controls relating to these areas of ScottishPower's
business for the five year period commencing April 1, 2000 are currently being
reviewed by regulatory authorities in the U.K., as well as those relating to
supply and generation. ScottishPower believes that it has high standards of
operation and customer service. Nevertheless, ScottishPower is unable to judge
accurately the outcome of these reviews and there can be no assurance that they
will not materially affect profits. It is expected that all the results of these
reviews will be known by November 1999.

A rewarding future

The combined company, to be called ScottishPower, will have approximately 7
million customers and 23,500 employees worldwide. The headquarters will be in
Glasgow, Scotland, with U.S. headquarters in Portland, Oregon.

PacifiCorp will continue to operate as Utah Power and Pacific Power in its
retail service territories and will retain a strong corporate presence in Utah.


Vote for:

o    Financial strength

o    Improved operational performance

o    Enhanced customer service

o    A new management team with a proven track record of integrating
     acquisitions, improving operating efficiencies and delivering benefits to
     shareholders.



Anticipated benefits of a PacifiCorp/ScottishPower
combination

o    Value for your PacifiCorp shares: Based on stock prices at the time the
     merger was announced, the implied premium for PacifiCorp shareholders was
     26% over the market price of PacifiCorp Common Stock. You particularly
     should note that the extent of any premium at the time of the merger will
     depend on the market price of the PacifiCorp Common Stock and ScottishPower
     Ordinary Shares, which fluctuate on a daily basis.

o    ScottishPower has a proven track record of integrating businesses while
     improving their operating efficiency.

o    The merger creates an opportunity to own a stake in a larger,
     faster-growing and financially stronger company.

o    A capable partner, ScottishPower has gained significant experience
     operating utility businesses in a competitive energy market. This knowledge
     will aid PacifiCorp as the U.S. energy market undergoes similar changes.

o    The combined organization will focus on accelerating PacifiCorp's strategy
     to improve the performance of its western U.S. electricity business. This
     renewed focus, together with the application of best practices from both
     companies, should increase operating efficiencies with the goals of
     enhancing shareholder value and improving customer service.

o    ScottishPower's objective is to play an active role in the economic
     prosperity of PacifiCorp's service territory.



The transaction

o    Under the terms of the agreement, PacifiCorp will become a wholly-owned
     subsidiary of ScottishPower.

o    Each share of PacifiCorp Common Stock will be converted tax free into a
     right to receive either 0.58 American Depository Shares (ADSs) of
     ScottishPower or 2.32 ScottishPower Ordinary Shares. (Each ADS represents
     four ScottishPower Ordinary Shares).

o    Fractional shares will be paid in cash.

o    Current PacifiCorp shareholders will own approximately 36% of the combined
     company.

o    Dividends will be paid quarterly and financial reports will be published
     quarterly. Dividends on ADSs will be paid in U.S. dollars; dividends on
     ordinary shares will be paid in pounds sterling.

Questions and Answers


Why am I being requested to vote?

As a shareholder of PacifiCorp, you are being asked to approve a merger
agreement in which PacifiCorp will become an indirect, wholly-owned subsidiary
of ScottishPower. PacifiCorp will retain its current name in its service
territories and its headquarters will remain in Portland.


What will I receive in the merger?

Following the merger, each share of PacifiCorp Common Stock will be converted
into a right to receive either 0.58 American Depository Shares (ADSs) of
ScottishPower or 2.32 ScottishPower Ordinary Shares. (Each ADS represents four
ScottishPower Ordinary Shares). Fractional shares will be bought by
ScottishPower in cash (U.S. Dollars).


What value does this equate to for my shares of PacifiCorp Common Stock?

The number of shares you receive in the merger is fixed. However, the value you
receive will fluctuate based on changes in the market price of ScottishPower
stock until the completion date of the merger.


What is a ScottishPower ADS?

An ADS (which stands for American Depository Share) is a negotiable receipt for
stock in a foreign company. An ADS allows U.S. investors to buy and sell shares
in overseas companies without trading in foreign markets. ScottishPower ADSs are
quoted and traded on the New York Stock Exchange in U.S. dollars and dividends
are paid in U.S. dollars. Each ScottishPower ADS represents ownership of four
ScottishPower Ordinary Shares.


What is a ScottishPower Ordinary Share?

ScottishPower issues Ordinary Shares, which are the equivalent of Common Stock
for a U.S. company. ScottishPower Ordinary Shares are traded and quoted on the
London Stock Exchange in pounds sterling and dividends are paid in pounds
sterling.



How and when are dividends paid on the ScottishPower ADSs?

ScottishPower currently pays dividends twice a year. When the merger is
complete, ScottishPower will move to quarterly payments, which are expected to
be made in February, May, August and November of each year. Dividends on
ScottishPower ADSs will be paid in U.S. dollars and dividends on ScottishPower
Ordinary Shares will be paid in pounds sterling.


What will be the dividend level for the combined company?

ScottishPower's dividends for the fiscal year ended March 31, 1999, were 22.5
pence per Ordinary Share. This is equal to $0.84 for every 0.58 of a
ScottishPower ADS, which is equal to a converted share of PacifiCorp Common
Stock. ScottishPower is committed to its stated aim of achieving 7-8% real
dividend growth annually until the U.K. regulatory reviews which take effect
from April 1, 2000, while maintaining a prudent level of dividend cover. It is
ScottishPower's current aim to deliver real dividend growth thereafter and this
will be re-examined once the outcome of these regulatory reviews is known.


Should I vote in favor of the merger between PacifiCorp and ScottishPower?

Your board of directors has determined that the merger is in the best interests
of PacifiCorp and its shareholders, and recommends that you vote in favor of the
merger.
