                                     ------

ITEM 1.        BUSINESS

HEI
- ---

HEI was incorporated in 1981 under the laws of the State of Hawaii and is a
holding company with subsidiaries engaged in the electric utility, savings bank,
freight transportation and other businesses operating primarily in the State of
Hawaii, and in the pursuit of independent power and integrated energy services
projects in Asia and the Pacific. HEI's predecessor, HECO, was incorporated
under the laws of the Kingdom of Hawaii (now the State of Hawaii) on October 13,
1891. As a result of a 1983 corporate reorganization, HECO became an HEI
subsidiary and common shareholders of HECO became common shareholders of HEI.

HECO and its operating subsidiaries, MECO and HELCO, are regulated electric
public utilities providing the only electric public utility service on the
islands of Oahu, Maui, Lanai, Molokai and Hawaii. HECO also owns all the common
securities of HECO Capital Trust I and HECO Capital Trust II (Delaware statutory
business trusts), which were formed to effect the issuances of $50 million of
8.05% cumulative quarterly income preferred securities in March 1997 and $50
million of 7.30% cumulative quarterly income preferred securities in December
1998, respectively, for the benefit of HECO, MECO and HELCO.

Besides HECO, HEI also owns directly or indirectly the following subsidiaries:
HEIDI and its subsidiaries, HEIDI Real Estate Corp. (inactive company) and ASB,
and the subsidiaries of ASB; HTB and its subsidiary; HEIIC; PECS; HEIPC and its
subsidiaries; HEI District Cooling, Inc.; ProVision Technologies, Inc.; Hycap
Management, Inc. and its subsidiary; Hawaiian Electric Industries Capital Trust
I; Hawaiian Electric Industries Capital Trust II and III (inactive entities);
and MPC and its subsidiaries (discontinued operations).

ASB, acquired in 1988, was the third largest financial institution in the State
of Hawaii and had 68 retail branches as of December 31, 1998. On December 6,
1997, ASB acquired substantially all of the Hawaii deposits of Bank of America,
FSB (BoA), most of its Hawaii branches and certain of its Hawaii-based loans.
The acquisition increased ASB's assets by $1.8 billion and its deposits by $1.7
billion. In March 1998, ASB formed a wholly owned operating subsidiary, ASB
Realty Corporation, which elects to be taxed as a real estate investment trust.

HTB was acquired in 1986 and provides ship assist and charter towing services
and owns YB, a regulated intrastate public carrier of waterborne freight among
the Hawaiian Islands. HEIIC was formed 

                                       1
<PAGE>
 
in 1984 and is a passive investment company which primarily holds investments in
leveraged leases. PECS was formed in August 1994 and currently is a contract
services company providing limited support services in Hawaii. HEIPC was formed
in 1995 to pursue, directly or through its subsidiaries or affiliates,
independent power and integrated energy services projects in Asia and the
Pacific. HEI District Cooling, Inc. was formed in August 1998 to develop, build,
own, operate and/or maintain, either directly or indirectly, central chilled
water cooling system facilities, and other energy related products and services
for commercial and residential buildings. ProVision Technologies, Inc. was
formed in October 1998 to sell, install, operate and maintain on-site power
generation equipment and auxiliary appliances in Hawaii and the Pacific Rim.
Hycap Management, Inc., including its subsidiary HEI Preferred Funding, LP (a
limited partnership in which Hycap Management, Inc. is the sole general
partner), and Hawaiian Electric Industries Capital Trust I (a Delaware statutory
business trust in which HEI owns all the common securities) were formed to
effect the issuance of $100 million of 8.36% HEI-obligated trust preferred
securities in February 1997.

Electric utility
- ----------------

HECO and subsidiaries and service areas

HECO, MECO and HELCO are regulated operating electric public utilities engaged
in the production, purchase, transmission, distribution and sale of electricity
on the islands of Oahu; Maui, Lanai and Molokai; and Hawaii, respectively. HECO
was incorporated under the laws of the Kingdom of Hawaii (now State of Hawaii)
in 1891. HECO acquired MECO in 1968 and HELCO in 1970.

In 1998, the electric utilities' revenues and operating income amounted to
approximately 68% and 79%, respectively, of HEI's consolidated revenues and
operating income. For additional information about HECO, see HEI's MD&A, HEI's
Quantitative and Qualitative Disclosures About Market Risk and HEI's
Consolidated Financial Statements, incorporated herein by reference to pages 26
to 39, 39 to 41 and 42 to 65, respectively, in HEI's 1998 Annual Report to
Stockholders, and HECO's MD&A, HECO's Quantitative and Qualitative Disclosures
About Market Risk and HECO's consolidated financial statements incorporated by
reference to pages 3 to 10, 10 to 11 and 12 to 34, respectively, of HECO's 1998
Annual Report to Stockholder, portions of which are filed as HECO Exhibit 13.

The islands of Oahu, Maui, Lanai, Molokai and Hawaii have a combined population
currently estimated at 1,136,000, or approximately 95% of the population of the
State of Hawaii, and comprise a service area of 5,766 square miles. The
principal communities served include Honolulu (on Oahu), Wailuku and Kahului (on
Maui) and Hilo and Kona (on Hawaii). The service areas also include numerous
suburban communities, resorts, U.S. Armed Forces installations and agricultural
operations.

HECO, MECO and HELCO have nonexclusive franchises from the state covering
certain areas, which authorize them to construct, operate and maintain
facilities over and under public streets and sidewalks. HECO's franchise covers
the City & County of Honolulu, MECO's franchises cover the County of Maui and
the County of Kalawao, and HELCO's franchise covers the County of Hawaii. Each
of these franchises will continue in effect for an indefinite period of time
until forfeited, altered, amended or repealed.

HECO and its subsidiaries derived approximately 10% of their operating revenues
from the sale of electricity to various federal government agencies in 1998,
1997 and 1996.

One of HECO's larger customers, the Naval Base at Barbers Point, Oahu, is
expected to be closed in 1999 with redevelopment of the base occurring through
2020. Considering (1) that the base closure will necessitate relocation of
essential flight operations and support personnel to another base on Oahu and
(2) the Naval Air Station Barbers Point Community Redevelopment Plan, HECO
anticipates that the closure is likely to result in an overall increase in
demand for electricity over time.


On March 8, 1994, President Clinton signed an Executive Order which mandates
that each federal agency develop and implement a program with the intent of
reducing energy consumption by 30% by the year 2005 to the extent that these
measures are cost effective. The 30% reductions will be measured relative to the
agency's 1985 energy use. HECO is working with various federal government
agencies to implement demand-side management programs which will help them
achieve their energy reduction objectives. In November 1995, HECO and the U.S.
General Services Administration entered into a Basic Ordering Agreement under
which HECO will arrange for financing and installation of energy conservation
projects at federal facilities in Hawaii. Under the Basic Ordering Agreement,
HECO undertook an air conditioning upgrade project at the federal office
building in downtown Honolulu, which project was completed in 1997. In 1997 and
1998, HECO also performed and completed  design work for solar water heating in
this federal office building and further work on this project is awaiting
funding. HECO has another project to perform engineering work for the U.S.
Postal Service, which is expected to be completed in March 1999 after which HECO
will submit a proposal for construction of the project. HECO also signed an
umbrella Basic Ordering Agreement with the Department of Defense (DOD) in
October 1996. During 1998, eight energy audits were completed on U.S. Navy
facilities on Oahu. These audits have thus far resulted in HECO undertaking two
energy-saving projects for the Navy, both of which are in progress. Neither HEI
nor HECO management can predict with certainty the impact of President Clinton's
Executive Order on the Company's or consolidated HECO's future financial
condition, results of operations or liquidity.

Integrated resource planning and requirements for additional generating capacity

As a result of a proceeding initiated in January 1990, the Public Utilities
Commission of the State of Hawaii (PUC) issued an order in March 1992 (and
revised it in May 1992) requiring the energy utilities in Hawaii to develop
integrated resource plans (IRPs). The goal of integrated resource planning is
the 

                                       5
<PAGE>
 
identification of demand-side and supply-side resources and the integration
of these resources for meeting near- and long-term consumer energy needs in an
efficient and reliable manner at the lowest reasonable cost. In its May 1992
order, the PUC adopted a "framework," which established both the process and the
guidelines for developing IRPs. The PUC's framework directs that each plan cover
a 20-year planning horizon with a five-year program implementation schedule and
states that the planning cycle will be repeated every three years. Under the
framework, the PUC may approve, reject or require modifications of the
utilities' IRPs.

The framework also states that utilities are entitled to recover all appropriate
and reasonable integrated resource planning and implementation costs, including
the costs of planning and implementing demand-side management (DSM) programs.
Under appropriate circumstances, the utilities may recover net lost revenues
resulting from DSM programs and earn shareholder incentives. The PUC has
approved IRP cost recovery provisions for HECO, MECO and HELCO. Pursuant to the
cost recovery provisions, the electric utilities may recover through a surcharge
the costs for approved DSM programs (including DSM program lost margins and
shareholder incentives), and other IRP costs incurred by the utilities and
approved by the PUC, to the extent the costs are not included in their base
rates.

The utilities have characterized their proposed IRPs as planning strategies,
rather than fixed courses of action, and the resources ultimately added to their
systems may differ from those included in their 20-year plans. Under the IRP
framework, the utilities are required to submit annual evaluations of their
plans (including a revised five-year program implementation schedule) and to
submit new plans on a three-year cycle. Prior to proceeding with the DSM
programs, separate PUC approval proceedings must be completed, in which the PUC
further reviews the details of the proposed programs and the utilities'
proposals for the recovery of DSM program expenditures, net lost margins and
shareholder incentives.


HECO's IRP.  HECO filed its second IRP with the PUC in January 1998.  A schedule
for the proceeding has been approved by the PUC, and the parties to the
proceeding are scheduled to file individual statements of position on the
reasonableness of HECO's IRP plan in May 1999.  Following the filing of
statements of position, the parties will meet informally to attempt to reach a
stipulation on issues where there is agreement, and/or establish additional
procedural steps, as required. The second IRP identified changes in key
forecasts and assumptions since the development of HECO's initial IRP, which was
filed in July 1993, modified in January 1994 and approved by the PUC as modified
in its March 1995 final decision and order (D&O). HECO's second IRP includes IRP
strategy options related to the transition to a more competitive environment in
the electric utility industry. The IRP is a flexible resource strategy that
allows the utility to make major decisions regarding the incremental
implementation of program options for both supply-side and demand-side
resources, based on HECO's IRP objectives and the best information available at
the time decisions must be made.

On the supply side, HECO's second IRP focuses on the planning for the next
generating unit addition in the 2009 time frame--a 107-MW simple cycle diesel
fired combustion turbine, which would be part of a 318-MW diesel fired 2-on-1
combined-cycle unit. Phases 2 and 3 of the combined-cycle unit would be
installed in 2013 and 2016, respectively.  In addition, pursuant to HECO's
generation asset management program, all existing generation units are currently
planned to be operated (future environmental considerations permitting) beyond
the 20-year IRP planning period (1998-2017).

HECO's second IRP includes the continuation of five energy efficiency DSM
programs, which are designed to reduce the rate of increase in Oahu's energy
use, defer construction of new generating units, minimize the state's dependence
on oil, and achieve savings for utility customers who participate in the
programs. The DSM energy efficiency programs include incentives for customers to
install efficient lighting, refrigeration, water-heating and air-conditioning
equipment and industrial motors. The PUC issued its final D&Os approving all
five of HECO's original energy efficiency DSM programs in 1996, and HECO began
implementing these programs in the third quarter of 1996. HECO filed
applications with the PUC for a commercial and industrial (C&I) load management
program in June 1996, and a residential load control program in September 1997.
HECO expects that these two load management DSM programs will be reviewed in
concept by the PUC in conjunction with HECO's second IRP. HECO plans to continue
the planning and implementation of DSM load management and energy 

                                       6
<PAGE>
 
efficiency programs that are cost effective and also minimize rate impacts to
all customers over the long-term.

MECO's IRP.  The PUC issued its final D&O in MECO's IRP proceeding in May 1996.
MECO's 20-year IRP includes the continuation of four energy efficiency DSM
programs similar to those developed for HECO. The supply-side resources proposed
by MECO, as updated in its July 1998 annual evaluation, include installing
approximately 214 MW of additional generation through the year 2013 on the
island of Maui, including 58 MW of generation at its Maalaea power plant site in
three increments from 1998-2002, and approximately 6 MW through the year 2013 on
each of the islands of Lanai and Molokai. The first 20 MW increment at Maalaea
was completed in December 1998. The PUC approved MECO's DSM water heating
program in July 1996, and MECO's C&I DSM programs in September 1996. MECO began
DSM program implementation in late 1996. MECO's second IRP annual evaluation was
filed with the PUC in July 1998. In September 1999, MECO will file a second IRP
for the 20-year IRP planning period from 2000-2019.

HELCO's IRP.  HELCO filed its second IRP with the PUC in September 1998. In
March 1999, HELCO filed a supplement to its second IRP to update the status of
planned near-term generation additions. The development of a procedural schedule
for the PUC proceeding in which HELCO's second IRP will be considered is
scheduled for April 1999. The second IRP identified changes in key forecasts and
assumptions since the development of HELCO's initial IRP, which was filed in
October 1993, modified in June 1994 and approved by the PUC as modified in its
May 1996 final D&O. Similar to HECO, HELCO's second IRP includes IRP strategy
options related to the transition to a more competitive environment in the
electric utility industry. The IRP is a flexible resource strategy that allows
the utility to make major decisions regarding the incremental implementation of
program options for both supply-side and demand-side resources, based on HELCO's
IRP objectives and the best information available at the time decisions must be
made.

On the supply-side, HELCO's second IRP focuses on the planning for generating
unit additions after near-term additions. The near term supply-side resources
proposed in HELCO's IRP plan include installing 40 MW of generation at its
Keahole power plant site and proceeding with a 60 MW purchase power agreement
with Encogen Hawaii, L.P. (Encogen) (see "HELCO power situation" below.) HELCO's
20-year plan also includes completing a 58 MW diesel-fired dual-train combined-
cycle (DTCC) unit at Keahole in 2006 (by adding an 18 MW heat recovery steam
turbine generator), adding another diesel-fired DTCC unit at a new West Hawaii
site in phases in the 2009-2017 timeframe, undertaking transmission and
distribution efficiency improvement projects, and conducting alternate energy
and dispersed generation resource studies.  HELCO's second IRP includes the
continuation of four energy efficiency DSM programs similar to those developed
for HECO. HELCO received interim approval for its four DSM programs in October
1995 and final approval in September 1996. HELCO began implementing its DSM
programs in December 1995.

HELCO power situation

Background. In 1991, HELCO identified the need, beginning in 1994, for
- ----------                                                            
additional generation to provide for forecast load growth while maintaining a
satisfactory generation reserve margin, to address uncertainties about future
deliveries of power from existing firm power producers and to permit the
retirement of older generating units. Accordingly, HELCO proceeded with plans to
install at its Keahole power plant site two 20-MW combustion turbines (CT-4 and
CT-5), followed by an 18 MW heat recovery steam generator (ST-7), at which time
these units would be converted to a 58 MW DTCC unit. In January 1994, the PUC
approved expenditures for CT-4, which HELCO had planned to install in late 1994.

The timing of the installation of HELCO's phased DTCC unit at the Keahole power
plant site has been revised on several occasions due to delays in (a) obtaining
approval from the Hawaii Board of Land and Natural Resources (BLNR) of a
Conservation District Use Permit (CDUP) amendment and (b) obtaining from the
Department of Health of the State of Hawaii (DOH) and the U.S. Environmental
Protection Agency (EPA) a Prevention of Significant Deterioration/Covered Source
permit (PSD permit) for the 

                                       7
<PAGE>
 
Keahole power plant site. The delays are primarily attributable to lawsuits,
claims and petitions filed by independent power producers and other parties.
Subject to satisfactory resolution of the CDUP amendment, PSD permit and other
matters, HELCO's current plan continues to contemplate that CT-4 and CT-5 will
be added to its system. In December 1998, HECO deferred plans for ST-7 to
approximately 2006 or 2007, unless the Encogen facility (described below) is not
placed in service as planned, and removed ST-7 costs from construction work-in-
progress as described below.

CDUP amendment. On July 10, 1997, the Third Circuit Court of the State of Hawaii
- ---------------                                                                 
issued its Amended Findings of Fact, Conclusions of Law, Decision and Order
addressing HELCO's appeal of an order of the BLNR, along with other consolidated
civil cases relating to HELCO's application for a CDUP amendment. This decision
allows HELCO to use its Keahole property as requested in its application. An
amended order to the same effect was issued on August 18, 1997. Final judgments
have been entered in all of the consolidated cases. Appeals with respect to the
final judgments for certain of the cases have been filed with the Hawaii Supreme
Court. Motions filed with the Third Circuit Court to stay the effectiveness of
the judgments pending resolution of the appeals were denied in April and July
1998 (in response to a motion for reconsideration). In August 1998, the Hawaii
Supreme Court denied nonhearing motions for stay of final judgment pending
resolution of the appeals. Management believes that HELCO will ultimately
prevail on appeal and that the final judgments of the Third Circuit Court will
be upheld.

PSD permit. In November 1995, the EPA declined to sign HELCO's PSD permit for
- ----------                                                                   
the combined-cycle unit. HELCO revised its permit application and, in 1997, the
EPA approved a revised draft permit and the DOH issued a final PSD permit for
HELCO's DTCC unit. Nine appeals of the issuance of the permit were filed with
the EPA's Environmental Appeals Board (EAB) in December 1997.

On November 25, 1998, the EAB issued an Order Denying Review in Part and
Remanding in Part. The EAB denied appeals of the permit that were based on
challenges to (1) DOH's use of a netting analysis (with respect to nitrogen
oxide (NOx) emissions), (2) DOH's determination of Best Available Control
Technology (BACT) for control of sulfur dioxide emissions, and (3) certain
aspects of DOH's ambient air and source impact analysis. However, the EAB
concluded that DOH had not adequately responded to comments that had been made
during the public comment period that data relating to certain ambient air
concentrations were outdated or were measured at unrepresentative locations. The
EAB remanded the proceedings and directed DOH to reopen the permit for the
limited purpose of (1) providing an updated air quality impact report
incorporating current data on sulfur dioxide and particulate matter ambient
concentrations and (2) providing a sufficient explanation of why the carbon
monoxide and ozone data used to support the permit are reasonably
representative, or performing a new air quality analysis based on data shown to
be representative of the air quality in the area to be affected by the project.
The EAB directed DOH to accept and respond to public comments on DOH's decisions
with respect to these issues and ruled that any further appeals of its decision
would be limited to the issues addressed on remand.

On December 4, 1998, HELCO filed with the EAB a motion for reconsideration of
its November 25, 1998 Order, contending that the DOH adequately responded to
public comments about the air quality data used in the air permit application.
The Keahole Defense Coalition (KDC) and Kawaihae Cogeneration Partners (KCP)
also filed motions for reconsideration in December 1998. On March 8, 1999, the
EAB issued an Order denying the motions for reconsideration which had been filed
by HELCO, KDC and KCP.

As a result of the EAB's decision on November 25, 1998 and its denial of all
motions for reconsideration on March 8, 1999, there has been a further delay in
HELCO's construction of CT-4 and CT-5. The actual length of the delay will
depend on the actions needed to address the EAB's rulings, but is expected to
delay installation until 2000 or early 2001. Despite this additional delay,
HELCO believes that the PSD permit will eventually be obtained, and CT-4 and CT-
5 will be built. Although management believes it has acted prudently with
respect to this project, effective December 1, 1998, HELCO decided to
discontinue, for financial reporting purposes, the accrual of an Allowance For
Funds Used During Construction (AFUDC) on CT-4 and CT-5 (which would have been
approximately 

                                       8
<PAGE>
 
$0.4 million after tax per month). The length of the delays to date and
potential further delays were factors considered by management in its decision
to discontinue the accrual of AFUDC.

In 1998, HELCO determined that ST-7 would not be needed in the immediate future
and removed $0.8 million in costs accumulated against ST-7 from construction
work-in-progress, writing off $0.6 million and reclassifying $0.2 million in
costs to inventory.

Declaratory judgment actions. In February 1997, KDC and three individuals
- ----------------------------                                             
(Plaintiffs) filed a lawsuit in the Third Circuit Court of the State of Hawaii
against HELCO, the director of the DOH, and the BLNR, seeking declaratory
rulings with regard to five counts alleging that, with regard to the Keahole
project, one or more of the defendants had violated, or could not allow the
plant to operate without violating, the State Clean Air Act, the State Noise
Pollution Act, conditions of HELCO's conditional use permit, covenants of
HELCO's land patent and Hawaii administrative rules regarding standard
conditions applicable to land permits. The Complaint was amended in March of
1998 to add a sixth count, claiming that an amendment to a provision of the land
patent (relating to the conditions under which the State could repurchase the
land) is void and that the original provision should be reinstated. Cross
motions for summary judgment were denied without explanation by orders filed in
March 1998. The court subsequently granted Plaintiffs' motion to clarify the
issues involved in one count of the complaint, but HELCO does not believe that
the court's ruling on this motion or related findings are significant with
respect to the ultimate outcome of the case. In December 1998, the case was set
for jury trial in May 1999.

Based on the discovery and status conferences to date, HELCO believes that there
are few, if any, issues of fact requiring jury resolution. Accordingly, all
parties have filed motions or taken other actions related to the various counts
in the lawsuit with the objective of allowing the Court to resolve all purely
legal issues before the scheduled trial date.

The parties are pursuing an agreement stipulating to the facts relating to Count
I (Clean Air Act). On February 25, 1999, Plaintiffs filed a statement limiting
the scope of Counts III and IV. On January 22, 1999, Plaintiffs filed a Motion
for Reconsideration of the Court's March 1998 order denying its Motion for
Summary Judgment on Counts II (State Noise Pollution Act), III (violation of
CDUP) and IV (violation of land patent). HELCO also filed a Motion for
Reconsideration of the Court's March 1998 order denying its Motion for Summary
Judgment on Count II. A hearing on these matters was held on February 16, 1999.
At that hearing, DOH notified the Court and the parties of a change in its
interpretation of the noise rules promulgated under the State Noise Pollution
Act. The change in interpretation would adversely impact HELCO's Keahole plant
by applying the noise standard applicable to the emitter property (which DOH
claims to be 55 dba (daytime) and 45 dba (nighttime) standard) rather than the
previously-applied noise standard of the receptor properties in the surrounding
Agricultural Park (a 70 dba standard). The Court postponed the hearing until
February 25, 1999 in order to allow DOH to file its position in writing on
February 22, 1999.

In response to the new position announced by the DOH, on February 23, 1999 HELCO
filed a declaratory judgment action against DOH, alleging that the noise rules
were invalid on constitutional grounds. At the hearing on February 25, 1999, the
Court ordered that:  HELCO serve the complaint on DOH and the Director of
Health; HELCO stipulate to allow KDC and BLNR/DLNR to intervene in the new
lawsuit; HELCO file a Motion for Summary Judgment on the claims in the new
lawsuit by March 19, 1999; and the hearing on all legal issues relating to noise
matters be set for March 31, 1999. A draft order consolidating the new lawsuit
with the KDC lawsuit is being circulated, but Plaintiffs are opposing the
consolidation on the grounds that HELCO has not timely raised the claims alleged
in the new lawsuit. On March 2, 1999, HELCO filed in the KDC lawsuit a motion to
file a cross-claim against the Director of Health and a third-party complaint
against DOH, which motion is also set for hearing on March 31, 1999.

BLNR and DOH filed, and HELCO joined in, a motion for partial summary judgment
on Count VI (amendment of land patent), and Plaintiffs filed a cross-motion for
summary judgment on that Count. A hearing on these matters was held on March 5,
1999, with the Court taking the matters under advisement.

                                       9

Two additional cases were filed in 1998. In March 1998, Plaintiff Ratliff filed
a complaint for declaratory judgment against HELCO, the BLNR and the Department
of Land and Natural Resources of the State of Hawaii (DLNR). The complaint
alleges a violation of plaintiff's constitutional due process rights because the
land use conditions (if any) which apply to HELCO's use of the Keahole site were
determined administratively by the DLNR (through a letter issued to HELCO in
January 1998) rather than being decided by the BLNR in a contested case. Also
filed with the complaint was a motion to stay enforcement of the DLNR letter,
which motion was denied in April 1998. In May 1998, Waimana Enterprises, whose
subsidiary is a partner in KCP, filed a lawsuit in the Third Circuit Court of
the State of Hawaii, asking for a declaration that the January 1998 DLNR letter
is void and seeking an injunction to prevent HELCO from further construction
until the Court or the BLNR, at a public hearing, determines what conditions and
limitations apply and whether HELCO is in compliance with them. At a hearing on
February 8, 1999, the parties agreed, and the Court orally ordered, the
consolidation of the Ratliff lawsuit with the KDC lawsuit and the dismissal with
prejudice of the Waimana lawsuit. Ratliff filed a Motion for Summary Judgment
with regard to the claims in her lawsuit and BLNR and DOH, joined by HELCO, also
filed a Motion for Summary Judgment in that lawsuit. A hearing on those motions
was held on March 9, 1999, with the Court taking the matter under advisement.

HELCO intends to vigorously defend against the claims raised in these 1997 and
1998 cases and, based on the status of the cases to date, management believes
the final resolution of these cases will not prevent it from constructing CT-4
and CT-5 at Keahole.

IPP complaints. Two independent power producers (IPPs), KCP and Enserch
- --------------                                                         
Development Corporation (Enserch), filed separate complaints against HELCO with
the PUC in 1993 and 1994, respectively, alleging that they are entitled to power
purchase contracts to provide HELCO with additional capacity, which they claimed
would be a substitute for HELCO's planned 58 MW DTCC unit at Keahole.

In September 1995, the PUC allowed HELCO to continue to pursue construction of
and commit expenditures for the second combustion turbine (CT-5) and the steam
recovery generator (ST-7) for its planned DTCC unit, but stated in its order
that "no part of the project may be included in HELCO's rate base unless and
until the project is in fact installed, and is used and useful for utility
purposes." The PUC also ordered HELCO to continue negotiating with the IPPs and
held that the facility to be built (i.e., either HELCO's or one of the IPP's)
should be the one that can be most expeditiously put into service at "allowable
cost."

The current status of the IPPs' PUC complaints, and of a complaint filed by Hilo
Coast Power Company (HCPC) in April 1997, is as follows:

     Enserch complaint. On January 16, 1998, HELCO filed with the PUC an
     -----------------                                                  
     application for approval of a power purchase agreement for a 60 MW (net)
     facility and an interconnection agreement with Encogen, an Enserch
     affiliate, both dated October 22, 1997. The agreements were entered into
     following a settlement agreement between Enserch and HELCO and are subject
     to PUC approval. The parties to the proceeding include HELCO, Encogen and
     the Consumer Advocate. Motions to intervene filed by KCP, HCPC and one
     other IPP were denied by the PUC. KCP filed a notice of appeal, which was
     denied by the Hawaii Circuit Court of the First Circuit by written order
     filed on February 8, 1999. The Consumer Advocate filed a Statement of
     Position on December 11, 1998, in which it recommended that an evidentiary
     hearing be held, following additional discovery, to address its issues and
     concerns regarding the agreements. The parties signed an amendment to the
     power purchase agreement on January 14, 1999 which, in part, provides that
     either party may terminate the agreement if the PUC does not issue an order
     within eighteen (18) months (extended from twelve (12) months originally in
     the agreement) from the submission of the application. The PUC has
     established a schedule of proceedings in 1999 for approval of the
     agreement. The schedule provides the PUC with the opportunity to issue a
     decision within the amendment's six-month extension period, which ends on
     July 16, 1999.

     KCP complaint. In January 1996, the PUC ordered HELCO to continue in good
     -------------                                                            
     faith to negotiate a power purchase agreement with KCP. In May 1997, KCP
     filed a motion for unspecified "sanctions" against HELCO for allegedly
     failing to negotiate in good faith. In June 1997, KCP 

                                       10
<PAGE>
 
     filed a motion asking the PUC to designate KCP's facility as the next
     generating unit on the HELCO system and to determine the "allowable cost"
     which would be payable by HELCO to KCP. HELCO filed memoranda in opposition
     to KCP's motions. The PUC held an evidentiary hearing in August 1997. KCP
     filed two other motions, which HELCO opposed, to supplement the record. The
     PUC issued an Order in June 1998 which denied all of KCP's pending motions;
     provided rulings and/or guidance on certain avoided cost and contract
     issues; directed HELCO to prepare an updated avoided cost calculation that
     includes the Encogen agreement; and directed HELCO and KCP to resume
     contract negotiations. HELCO filed a motion for partial reconsideration
     with respect to one avoided cost issue. The PUC granted HELCO's motion and
     modified its order in July 1998. HELCO resumed negotiations with KCP in
     compliance with the Order, but no agreement has been reached.

     HCPC complaint. In April 1997, HCPC filed a complaint against HELCO with
     --------------                                                          
     the PUC, requesting an immediate hearing on HCPC's offer for a new 20-year
     power purchase contract for its existing facility, which is proposed to be
     expanded from 22 MW to 32 MW. HCPC's existing power purchase agreement is
     scheduled to terminate at the end of 1999. The PUC converted the HCPC
     complaint into a purchased power contract negotiation proceeding. HCPC
     submitted a new proposal in the proceeding in February 1998 for a 30-year
     contract. An evidentiary hearing, which was limited to three issues
     affecting the calculation of avoided costs, including which of HELCO's
     planned unit additions could be deferred or displaced by a new power
     purchase agreement (PPA) with HCPC, was held in April 1998. On November 25,
     1998, the PUC issued a Decision and Order in the HCPC complaint docket. The
     Decision and Order states that (1) "whether the next immediate unit is
     ultimately provided by Encogen at Hamakua or HELCO at Keahole, HCPC can
     negotiate to provide the increment of power following the next immediate
     unit", and "HELCO's sunk and parallel planning costs for CT-4 and CT-5 will
     not be part of the avoided cost calculation", and (2) the reconductoring of
     a transmission line to accept HCPC's proposed 32 MWs would be of system-
     wide benefit, and the cost would not be included in the avoided cost
     calculation. The decision also addressed a system-modeling issue, and
     required that the avoided cost calculation be based on the same assumptions
     used in the last (April 1998) avoided cost calculation. The PUC directed
     that HCPC and HELCO continue to negotiate a power purchase agreement and by
     February 1, 1999 submit to the PUC either a finalized agreement or reports
     informing the PUC of the matters preventing the finalization of an
     agreement. The parties entered into negotiations but have not yet finalized
     an agreement. Status reports were filed by HCPC on February 1, 1999 and by
     HELCO on February 2, 1999 (HELCO had received a one-day extension). In its
     status report, HELCO requested a hearing with respect to the pricing and
     avoided cost issues. On February 24, 1999, the PUC issued an Order
     reopening the docket to further assist HELCO and HCPC in negotiating an
     agreement and giving each party an opportunity to file supplemental
     memoranda by March 12, 1999. On March 8, 1999, HELCO filed a Motion for
     Partial Reconsideration of the Order, stating that it would waive its right
     to a hearing if it were allowed to present oral arguments to the PUC. The
     PUC granted HELCO's motion, and oral arguments have been scheduled for
     March 25, 1999.

Management cannot determine at this time whether the PUC will approve the
Encogen power purchase agreement or whether the negotiations with KCP or HCPC or
related PUC proceedings will result in the execution and/or PUC approval of a
power purchase agreement. Under HELCO's current estimate of generating capacity
requirements, there is a need for capacity in addition to the capacity which
might be provided by any one of the IPPs. Management cannot determine at this
time the impact on its plans with regard to the installation of units CT-4 and
CT-5 at the Keahole power plant site if power purchase contracts with two or
more of the IPPs were to be negotiated, approved by the PUC and implemented.

BLNR petition. On August 5, 1998, KDC filed with the BLNR a Petition for
- --------------                                                          
Declaratory Ruling under Section 91-8, Hawaii Revised Statutes. The petition
alleges that all conditions in Hawaii Administrative Rules 13-2-21 apply to
HELCO's default entitlement to use its Keahole site, that the letter issued to
HELCO by the DLNR in January 1998 was erroneous because it failed to incorporate
all conditions applicable to the existing permits, and that the DOH issued three
separate Notices of Violation (NOVs) 

                                       11
<PAGE>
 
to HELCO in 1992 and 1998 for violation of clean air rules, which NOVs
constitute violations under the existing permits and render such permits null
and void. The petition requests that the BLNR commence a contested case on the
petition; that the BLNR determine that HELCO has violated the terms of its
existing conditional use permits, causing such permits to be null and void; and
that the BLNR determine that HELCO has violated the conditions applicable to its
default entitlement, such that HELCO should be enjoined from using the Keahole
property under such default entitlement. The BLNR requested that each of the
parties submit statements of position on the issues and HELCO filed its
statement in October 1998. The last of the responsive submissions of the parties
was filed in December 1998. The matter has not yet been set before BLNR for a
determination of whether a hearing will be held.

Complaint and motion for temporary restraining order. On August 5, 1998, KDC
- -----------------------------------------------------                       
filed in the Third Circuit Court of the State of Hawaii a Complaint and Motion
for Temporary Restraining Order and Preliminary Mandatory Injunction against
HELCO and the Chief Engineer, Department of Public Works, County of Hawaii, and
on August 6, 1998, filed an amended complaint. The complaint and amended
complaint do not identify a cause of action, but allege that the City Engineer
issued eight building permits to HELCO for the expansion of the Keahole
Generating Station without requiring HELCO to obtain a final Covered Source
Permit as a precondition to construction on the belief that the DOH and the EPA
had authorized certain construction activities. The complaints call for the
suspension and revocation of the eight building permits and an injunction to
prevent further construction by HELCO. The motion calls for the Court to mandate
that the Chief Engineer suspend or revoke certain building permits for
structures, improvements and facilities which are directly or solely associated
with or which are of a permanent nature aimed at completing CT-4, CT-5 and ST-7
and enjoin HELCO from construction at Keahole while the permits are suspended or
revoked.

The Court issued a temporary restraining order in September 1998. However, HELCO
obtained eight new building permits and the old permits were voided. HELCO then
moved to dismiss the case for mootness and, on November 16, 1998, the Court
issued a minute order granting the motion to dismiss and denying plaintiff's
request for attorneys fees. The final order granting the motion to dismiss was
filed on December 24, 1998.

DOH Notice of Violation. In July 1998, the DOH issued a NOV to HELCO for items
- -----------------------                                                       
allegedly constituting unauthorized construction activity at the Keahole
Generating Station prior to receipt of an effective PSD permit for CT-4 and CT-
5. The NOV required HELCO to immediately halt construction activities on pipe
rack foundations, a retaining wall and an oil/water separator, and imposed a
fine of $48,800. HELCO complied with the stop work order on the designated items
and paid the fine.

EPA Notice of Violation. In September 1998, the EPA issued a NOV to HELCO
- -----------------------                                                  
stating that HELCO violated the Hawaii State Implementation Plan by commencing
construction activities at the Keahole generating station without first
obtaining a final air permit. By law, 30 days after the NOV, the EPA may issue
an Order requiring compliance with applicable laws, assessing penalties and/or
commencing a civil action seeking an injunction; however, no Order has yet been
issued. HELCO has put the EPA on notice that certain construction activities not
affected by the NOV are continuing, and has received approval to proceed with
certain construction activities. However, HELCO has halted work on other
construction activities at Keahole until further notice is provided or approval
is obtained from the EPA, or until the final air permit is received.

Costs incurred. If it becomes probable that CT-4 and/or CT-5 will not be
- --------------                                                          
installed, HELCO may be required to write-off a material portion of the costs
incurred in its efforts to put these units into service. As of December 31,
1998, HELCO's costs incurred in its efforts to put CT-4 and CT-5 into service
amounted to $74.9 million, including approximately $30.1 million for equipment
and material purchases, approximately $23.3 million for planning, engineering,
permitting, site development and other costs and approximately $21.5 million for
AFUDC accrued through November 30, 1998, after which HELCO stopped accruing
AFUDC (see discussion under "PSD Permit" above).

Contingency planning. In June 1995, HELCO filed with the PUC its generation
- --------------------                                                       
resource contingency plan detailing alternatives and mitigation measures to
address the delays that have occurred in obtaining

                                       12
<PAGE>
 
the permits necessary to construct its combined-cycle unit at Keahole. Actions
under the plan have helped HELCO maintain its reserve margin and reduce the risk
of near-term capacity shortages. In January 1996, the PUC opened a proceeding to
evaluate HELCO's contingency resource plan and HELCO's efforts to insure system
reliability. HELCO has filed reports with the PUC from time to time updating the
contingency plan and the status of implementing the plan. The most recent update
was filed on March 1, 1999. Due to the delays in adding new generation, and the
expiration of the HCPC power purchase contracts for 22 MW at the end of 1999,
HELCO's reserve margin (based on firm capacity without considering as-available
resources such as wind and run-of-the-river hydroelectric generators) in 2000
will be less than the margin called for by generation planning criteria until
new generation is added. The addition of new generation is not expected to occur
until April 2000, at the earliest. As a result, HELCO will have sufficient
generation to cover projected monthly system peak loads with units on scheduled
maintenance, but may not always have enough reserve margin to make up for the
unexpected outage of one of its largest generation units beginning in January
2000 until new generation is added.

Nonutility generation

The Company has supported state and federal energy policies which encourage the
development of alternate energy sources that reduce dependence on fuel oil.
Alternate energy sources range from wind, geothermal and hydroelectric power, to
energy produced by the burning of bagasse (sugarcane waste) and coal. Other
nonoil projects include purchased power arrangements with two IPPs, one
operating a generating unit burning municipal waste and the other a fluidized
bed unit burning coal.

HECO power purchase agreements.  HECO currently has three major power purchase
agreements. In March 1988, HECO entered into a power purchase agreement with AES
Barbers Point, Inc. (AES-BP, now known as AES Hawaii, Inc.), a Hawaii-based
cogeneration subsidiary of The AES Corporation (formerly known as Applied Energy
Services, Inc.) of Arlington, Virginia. The agreement with AES-BP, as amended in
August 1989, provides that, for a period of 30 years, HECO will purchase 180 MW
of firm capacity. The AES-BP 180-MW coal-fired cogeneration plant, which became
operational in September 1992, utilizes a "clean coal" technology. The facility
is designed to sell sufficient steam to be a "Qualifying Facility" under the
Public Utility Regulatory Policies Act of 1978 (PURPA).

In October 1988, HECO entered into an agreement with Kalaeloa Partners, L.P.
(Kalaeloa), a limited partnership whose sole general partner is an indirect,
wholly owned subsidiary of ASEA Brown Boveri, Inc. (ABB), which has guaranteed
certain of Kalaeloa's obligations and, through affiliates, has contracted to
design, build, operate and maintain the facility. The agreement with Kalaeloa,
as amended, provides that HECO will purchase 180 MW of firm capacity for a
period of 25 years beginning in May 1991. The Kalaeloa facility, which was
completed in the second quarter of 1991, is a combined-cycle operation,
consisting of two oil-fired combustion turbines burning low sulfur fuel oil
(LFSO) and a steam turbine which utilizes waste heat from the combustion
turbines. The facility is designed to sell sufficient steam to be a "Qualifying
Facility" under PURPA. As of February 28, 1997, the ownership of Kalaeloa was
restructured so that 1% is now owned by the ABB subsidiary as the general
partner and 99% is owned by Kalaeloa Investment Partners (KIP) as the limited
partner. KIP is a limited partnership comprised of  PSEG Hawaiian Management,
Inc. and PSEG Hawaiian Investment, Inc. (nonregulated affiliates of Public
Service Enterprise Group Incorporated) and Harbert Power Corporation. A second
phase of the February 28, 1997 transaction, which is still pending, would
transfer the general partner interest from the ABB subsidiary to an entity
affiliated with the owners of KIP. A modification of the existing ABB Guarantee
of Kalaeloa obligations may be part of the second phase. HECO must consent to
any changes in the ABB Guarantee.

HECO also entered into a power purchase contract in March 1986 and a firm
capacity amendment in April 1991 with the City and County of Honolulu, which
built a 64-MW refuse-fired plant (H-Power). The H-Power facility began to
provide firm energy in 1990 and currently supplies HECO with 46 MW of firm
capacity. The firm capacity amendment provides that HECO will purchase firm
capacity until mid-2015.

                                       13
<PAGE>
 
The PUC has approved and allowed rate recovery for the costs related to HECO's
three major power purchase agreements which provide a total of 406 MW of firm
capacity, representing 24% of HECO's total generating and firm purchased
capability on the island of Oahu as of December 31, 1998.

MECO and HELCO power purchase agreements.  As of December 31, 1998, MECO and
HELCO had power purchase agreements for 16 MW and 52 MW of firm capacity,
respectively, representing 6% and 24% of their respective total generating and
firm purchased capabilities.

MECO has a power purchase agreement with Hawaiian Commercial & Sugar Company
(HC&S) for 16 MW of firm capacity. In October 1998, MECO entered into a letter
agreement with HC&S which extended the power purchase agreement through December
31, 2001, and year-to-year thereafter, subject to termination on or after
January 1, 2002, on not less than two years prior written notice by either
party. On March 2, 1998, an HC&S unit failed and HC&S lost 10 MW of generating
capacity. HC&S is currently in negotiations to replace the unit, but the unit is
not expected to be in operation until the fourth quarter of 2000. HC&S, however,
is still able to meet its contract obligations to MECO.

HELCO has a 35 year power purchase agreement with Puna Geothermal Venture (PGV)
for 30 MW of firm capacity expiring on December 31, 2027. On February 12, 1996,
HELCO and PGV executed an amendment to the power purchase agreement for 5 MW of
firm capacity in addition to the 25 MW then being supplied. In August 1996, the
PUC approved the amendment and, in September 1996, PGV began supplying 5 MW of
additional firm power. Although PGV is contracted to provide 30 MW of firm
power, it is currently providing only 24.5 MW. Restoring firm capacity to the
contracted amount will require PGV to obtain the necessary permits and drill
additional production and reinjection wells. PGV had indicated to HELCO that it
is on schedule to restore its firm capacity to 30 MW by mid-1999.

In December 1994, at a time when the HCPC contract was for delivery of 18 MW,
HCPC filed a Chapter 11 bankruptcy petition. In July 1995, the bankruptcy court
approved an amended and restated power purchase agreement with HCPC for 22 MW of
firm capacity and the dismissal of HCPC from bankruptcy. That agreement will
terminate on December 31, 1999. HCPC is currently in negotiations with HELCO for
a possible power purchase agreement for 22 MW of firm capacity for two years and
32 MW of firm capacity over a period of 30 years. See the "HELCO power
situation" section above.

In October 1997, HELCO entered into an agreement with Encogen, a limited
partnership whose general partners are wholly owned special-purpose subsidiaries
of Enserch and Jones Capital Corporation. Enserch Corporation and J.A. Jones,
Inc., the parent companies of Enserch and Jones Capital Corporation,
respectively, have guaranteed certain of Encogen's obligations, and an affiliate
of Enserch will be contracted to operate and maintain the facility. The
agreement provides that HELCO will purchase 60 MW (net) of firm capacity for a
period of 30 years. The facility will consist of two oil-fired combustion
turbines and a steam turbine which utilizes waste heat from the combustion
turbines. The facility will be designed to sell sufficient steam to be a
"Qualifying Facility" under PURPA. HELCO submitted the agreement to the PUC for
approval in January 1998 and the PUC has established a schedule of proceedings
in 1999 for approval of the agreement. See "HELCO Power Situation" above.

Fuel oil usage and supply

All rate schedules of the Company's electric utility subsidiaries contain energy
cost adjustment clauses whereby the charges for electric energy (and
consequently the revenues of the electric utility subsidiaries generally)
automatically vary with changes in the weighted-average price paid for fuel oil
and certain components of purchased energy costs, and the relative amounts of
company-generated power and purchased power. Accordingly, under these clauses,
changes in fuel oil and certain purchased energy costs are passed on to
customers. In the December 30, 1997 D&O's approving HECO and its subsidiaries'
fuel supply contracts, the PUC noted that, in light of the length of the fuel
supply contracts and the relative stability of fuel prices, the need for the
continued use of energy cost adjustment clauses will be the subject of
investigation in a generic docket or in a future rate case. In their rate
increase applications based on 1999 test years, MECO and HELCO stated that they
believe that their energy cost adjustment clauses continue to be necessary. See
discussion below under "Rates" and the "Energy cost adjustment clauses" section
in HECO's MD&A.

                                       14
<PAGE>
 
HECO's steam power plants burn LSFO. HECO's combustion turbine peaking units
burn Number 2 diesel fuel (diesel). MECO's and HELCO's steam power plants burn
medium sulfur fuel oil (MSFO) and their combustion turbine and diesel engine
generating units burn diesel. The LSFO supplied to HECO is primarily derived
from Indonesian and other Far East crude oils processed in Hawaii refineries.
The MSFO supplied to MECO and HELCO is derived from U.S. domestic crude oil
processed in Hawaii refineries.

In December 1997, HECO executed new contracts for the purchase of LSFO and the
use of certain fuel distribution facilities with Chevron Products Company
(Chevron) and Tesoro Hawaii Corp. dba BHP Petroleum Americas Refining Inc.
(Tesoro). These fuel supply and facilities operations contracts have a term of
seven years commencing January 1, 1998. The PUC approved the contracts and
issued a final D&O in December 1997 that permits the inclusion of costs incurred
under these contracts in HECO's energy cost adjustment clause. HECO pays market-
related prices for fuel supplies purchased under these agreements.

HECO, MECO, HELCO and affiliates, HTB and YB, executed new joint fuel supply
contracts with Chevron and Tesoro for the purchase of diesel and MSFO supplies
and for the use of certain petroleum distribution facilities for a period of
seven years commencing January 1, 1998. The PUC subsequently approved these
contracts and issued a final D&O in December 1997 that permitted the electric
utilities to include fuel costs incurred under these contracts in their
respective energy cost adjustment clauses. The electric utilities and HTB and YB
pay market-related prices for diesel and MSFO supplied under these agreements.

The diesel supplies acquired by the Lanai Division of MECO are purchased under a
contract with a local Chevron-brand wholesaler, Lanai Oil Co., Inc., executed on
February 13, 1997. The PUC issued a final D&O approving the contract in June
1997. The original term of the contract, which provides for the delivery of fuel
to MECO's Lanai  power plants, expired December 31, 1997. The contract continues
under a provision for extension on an "evergreen" basis until an agreed formal
extension becomes effective upon approval by the PUC which is expected in 1999.

See the fuel oil commitments information set forth in the "Fuel contracts and
other purchase commitments" section in Note 12 to HECO's Consolidated Financial
Statements.

The following table sets forth the average cost of fuel oil used to generate
electricity in the years 1998, 1997 and 1996:

</TABLE>

The average per-unit cost of fuel oil consumed to generate electricity for HECO,
MECO and HELCO reflects a different volume mix of fuel types and grades. In
1998, over 99% of HECO's generation fuel consumption consisted of LSFO. The
balance of HECO's fuel consumption was diesel. Diesel made up approximately 74%
of MECO's and 34% of HELCO's fuel consumption. The remainder of the fuel
consumption of MECO and HELCO consisted of MSFO. In general, MSFO is the least
costly fuel, diesel is the most expensive fuel and the price of LSFO falls
between the two on a per-barrel basis. The prices of LSFO, MSFO and diesel
declined over the course of 1998 and averaged approximately 25% below the
respective price levels prevailing in 1997. 1997 prices in turn had been largely
unchanged relative to prices prevailing during 1996.

In December 1997, HELCO and MECO exercised an option to extend for two years
their existing contracts with Hawaiian Interisland Towing, Inc. (HITI) for the
shipment of MSFO and diesel supplies from their fuel supplier's facilities on
Oahu to storage locations on the islands of Hawaii and Maui, respectively. The
PUC had approved these contracts and issued a final order in June 1994 that
permitted HELCO and MECO to include the fuel transportation and related costs
incurred under the original 

                                       15
<PAGE>
 
contracts in their respective energy cost adjustment clauses. Freight rates
charged under the contracts are related to published indices for industrial
commodities prices and labor costs. These contracts each include options for one
additional two-year extension. HELCO and MECO own the fuel oil and diesel fuel
when it is purchased from Chevron or Tesoro. HITI never takes title for the fuel
oil or diesel fuel, but does have custody and control while the fuel is in
transit from Oahu. If there were an oil spill in transit, HITI is contractually
obligated to indemnify HELCO and/or MECO. HITI has $700 million of insurance
coverage for oil spills. State law provides a cap of $700 million on liability
for releases of heavy fuel oil transported by tank barge interisland. HELCO
and/or MECO may be liable for any clean-up and/or fines that HITI or its
insurance carrier does not cover.

The Company estimates that 76% of the net energy generated and purchased by HECO
and its subsidiaries in 1999 will be generated from the burning of oil.
Increases in fuel oil prices are passed on to customers through the electric
utility subsidiaries' energy cost adjustment clauses. Failure by the Company's
oil suppliers to provide fuel pursuant to the supply contracts and/or
substantial increases in fuel prices could adversely affect consolidated HECO's
and the Company's financial condition, results of operations and/or liquidity.
HECO, however, maintains an inventory of fuel oil in excess of one month's
supply. HELCO and MECO maintain approximately a one month's supply of fuel oil.

Rates

HECO, MECO and HELCO are subject to the regulatory jurisdiction of the PUC with
respect to rates, issuance of securities, accounting and certain other matters.
See "Regulation and other matters--Electric utility regulation."

All rate schedules of HECO and its subsidiaries contain energy cost adjustment
clauses as described previously. Under current law and practices, specific and
separate PUC approval is not required for each rate change pursuant to automatic
rate adjustment clauses previously approved by the PUC. Rate increases, other
than pursuant to such automatic adjustment clauses, require the prior approval
of the PUC after public and contested case hearings. PURPA requires the PUC to
periodically review the energy cost adjustment clauses of electric and gas
utilities in the state, and such clauses, as well as the rates charged by the
utilities generally, are subject to change.

See the "Regulation of electric utility rates,"  "Recent rate requests" and
"Energy cost adjustment clauses" sections in HECO's MD&A.

Recent rate requests
Hawaiian Electric Company, Inc.
- -------------------------------

 .  In December 1993, HECO filed a request to increase rates based on a 1995 test
year. HECO requested a 4.1% increase (as revised), or $28.2 million in annual
revenues, based on a 13.25% return on average common equity (ROACE).

In December 1995, HECO received a final D&O authorizing a 1.3%, or $9.1 million,
increase in annual revenues, based on a 1995 test year and an 11.4% ROACE. The
final D&O required a refund to customers because HECO had previously received
interim increases totaling $18.9 million on an annualized basis, or $9.8 million
more than the amount that was finally approved.

Hawaii Electric Light Company, Inc.
- -----------------------------------

 .  In March 1995, HELCO filed a request to increase rates based on a 1996 test
year. In February 1996, HELCO revised its requested increase to 6.2%, or $8.9
million in annual revenues, based on a 12.5% ROACE.

In March 1996, HELCO received an interim D&O authorizing a 4.8%, or $6.8
million, increase in annual revenues, based on an 11.65% ROACE.  In April 1997,
HELCO received a final D&O which made the interim increase final.

 .  In March 1998, HELCO filed a request to increase rates 11.5%, or $17.3
million in annual revenues, based on a 1999 test year and a 12.5% ROACE,
primarily to recover costs relating to (1) an agreement, which is subject to PUC
approval, to buy power from Encogen's 60 MW plant and (2) adding two 

                                       16
<PAGE>
 
combustion turbines (CT-4 and CT-5) at HELCO's Keahole power plant. Due to the
EAB's denial of HELCO's motion for reconsideration of the EAB's November 25,
1998 decision (see "HELCO power situation--PSD permits" above), HELCO's test
year 1999 rate increase application was withdrawn in March 1999. A new
application is expected to be filed closer to the time when the new generation
facilities are expected to be completed.

Maui Electric Company, Limited
- ------------------------------

 . In February 1995, MECO filed a request to increase rates based on a 1996 test
year. MECO's final requested increase was 3.8%, or $5.0 million in annual
revenues, based on an 11.5% ROACE.

In January 1996, MECO received an interim D&O authorizing an increase of 2.8%,
or $3.7 million in annual revenues, based on an 11.5% ROACE, effective February
1, 1996. In April 1997, MECO received a final D&O authorizing a 2.9%, or $3.9
million increase in annual revenues, $0.2 million more annually than the interim
increase and based on an 11.5% ROACE.

 .  In May 1996, MECO filed a request to increase rates 13%, or $18.9 million in
annual revenues, based on a 1997 test year and a 12.9% ROACE, primarily to
recover the costs related to the anticipated 1997 addition of new generating
unit M17. In November 1996, MECO filed a motion with the PUC to approve a
stipulation between MECO and the Consumer Advocate which would provide MECO with
an increase in annual revenues of $1.5 million, based on an 11.65% ROACE. In May
1997, the stipulated increase was revised to $1.3 million after considering the
final decision in the 1996 test year case. The primary reason for the
stipulation was a delay in the expected in-service date for MECO's generating
unit M17 until late 1998, because of delays in obtaining the necessary PSD
permit from the DOH/EPA. In December 1997, MECO received a final D&O authorizing
no additional increase in annual revenues, based on an 11.12% ROACE.

 .  In January 1998, MECO filed a request to increase rates by 15.3%, or $22.4
million in annual revenues, based on a 12.75% ROACE and a 1999 test year,
primarily to recover the costs related to the addition of generating unit M17 in
late 1998. In November 1998, MECO revised its requested increase to 11.9%, or
$16.4 million, in annual revenues, based on a 12.75% ROACE. In December 1998,
MECO received an interim D&O, effective January 1, 1999, authorizing an 8.5%, or
$11.7 million, increase in annual revenues (subject to refund with interest,
pending the final outcome of the case), based on a ROACE of 11.12%, which was
the ROACE authorized in MECO's prior rate case.

PUC Show Cause Order

In March 1997, the PUC issued a show cause order to HECO requesting information
to assist the PUC in determining if it should reduce HECO's rates and require
HECO to refund any excess earnings to its ratepayers. The PUC noted that for
1996 HECO recorded a ROACE of 11.93% and a simple average rate of return on rate
base (ROR) of 9.70%, which exceeded the 11.40% ROACE and 9.16% ROR determined to
be reasonable by the PUC in HECO's last rate case. HECO filed a motion to close
the proceeding in March 1998, based on the fact that the actual returns for
1997--a 10.26% ROACE and an 8.75% ROR--were below the returns the PUC found to
be fair and reasonable in the last rate proceeding. The Consumer Advocate filed
with the PUC a statement that it did not oppose HECO's request to close the
proceedings. In November 1998 the PUC issued an order that granted HECO's motion
and closed the docket. This proceeding did not affect HECO's electric rates.

Property Damage Reserve

See the "Property damage reserve" section in HECO's MD&A.

Competition

Legislation has been introduced in Congress that would restructure the electric
utility industry with a view toward increasing competition by, for example,
allowing customers to choose their generation supplier. In addition, the PUC
instituted a proceeding in December 1996 to identify and examine the issues
surrounding electric competition and to determine the impact of competition on
the electric utility infrastructure in Hawaii. See the "Competition" section in
HECO's MD&A. Management cannot predict 

                                       17
<PAGE>
 
what changes, if any, may result from these efforts or what impact, if any, they
may have on the Company's or consolidated HECO's financial condition, results of
operations or liquidity.

The PUC proceeding seeks to identify and examine the issues surrounding electric
competition and to determine the impact of competition on the electric utility
infrastructure in Hawaii. In its order, the PUC recognized that Hawaii's stand-
alone island energy systems are different from the interconnected systems of the
contiguous states, but also recognized the need to determine how to respond in
Hawaii to changes occurring in the industry. The PUC set forth a preliminary
enumeration of the issues, including feasible forms of competition, the
regulatory compact, public interest benefits, long-term integrated resource
planning, appropriate treatment of potential stranded costs and the
identification of the objectives and the establishment of a time frame for the
introduction of competition in the electric industry. There are 19 parties in
the proceeding including the Consumer Advocate, HECO, HELCO, MECO, Citizens
Utilities (which serves the island of Kauai), the Department of Business,
Economic Development, and Tourism of the State of Hawaii (DBEDT), the Counties
of Maui, Hawaii and Kauai, the Department of Defense (the DOD, HECO's largest
customer), various IPPs and others. Following a number of meetings, and the
submission and presentation to the collaborative group of preliminary statements
of positions (SOPs), the parties individually submitted final statements of
position that were compiled and sent to the PUC in October 1998.

The position of HECO and its subsidiaries is that retail competition is not
feasible in Hawaii. The conditions making electric industry restructuring
feasible elsewhere generally are not present in Hawaii. Among other
considerations, none of the island electric systems are interconnected, the
island electricity markets are relatively small and there are barriers to entry
by new generation suppliers. HECO and its subsidiaries propose to achieve some
of the benefits of competition through proposals for (1) competitive bidding for
new generation, (2) performance-based ratemaking (which would include an index-
based price cap, an earnings sharing mechanism, and a benchmark incentive plan)
and (3) innovative pricing provisions (including rate restructuring, expanded
time-of-use rates, customer migration rates such as standby charges, flexible
pricing to encourage economic development and to compete with customer
generation options, new service options and two-part rates incorporating real-
time pricing). HECO suggests in its SOP that these proposals be implemented
through applications for PUC approval in a series of separate proceedings to be
initiated by HECO in 1999 and 2000.

While the other parties' SOPs generally support competitive bidding for new
generation, there is no consensus as to whether or as to the extent Hawaii's
electricity markets should be restructured to introduce further competition. For
example, the Consumer Advocate agrees that full scale retail generation
competition is not now feasible in Hawaii, but proposes immediate rate
unbundling and customer education, followed by rulemaking proceedings (1) to
open transmission and distribution access on a limited basis (such as when new
generation is needed) and determine the degree of any stranded cost recovery
through nonbypassable access charges, (2) to permit conservation and energy
management services to be provided to retail customers on a competitive basis,
and (3) to implement competition for other customer services (metering and
billing), as determined to be appropriate. The DOD also recognizes that retail
generation competition is not now feasible, and proposes rate unbundling, the
establishment of cost-based rates, the offering of additional rate options,
performance-based ratemaking, and investigation of the unbundling and separate
pricing of customer services. DBEDT proposes (1) rate unbundling, (2)
competition for customer services and energy efficiency services, and (3) if
additional analysis by the PUC confirms the feasibility of retail generation
competition on Oahu, open transmission and distribution access for generators,
divestiture of generation and customer service functions by utilities, and the
formation of independent system operators (all targeted for 2002).

The PUC will determine what procedural steps, if any, will follow. No timetable
has been set for such a determination. It is also possible that parties may seek
legislative action on their proposals.

Savings bank--American Savings Bank, F.S.B.
- -------------------------------------------

General

ASB was granted a federal savings bank charter in January 1987. Prior to that
time, ASB had operated since 1925 as the Hawaii division of American Savings &
Loan Association of Salt Lake City, Utah. As of December 31, 1998, ASB was the
third largest financial institution in the State of Hawaii with total assets of
$5.7 billion and deposits of $3.9 billion.

HEI agreed with the Office of Thrift Supervision's (OTS) predecessor regulatory
agency that ASB's regulatory capital would be maintained at a level of at least
6% of ASB's total liabilities, or at such greater amount as may be required from
time to time by regulation. Under the agreement, HEI's obligation to contribute
additional capital was limited to a maximum aggregate amount of approximately
$65.1 million. At December 31, 1998, HEI's maximum obligation to contribute
additional capital has been reduced to approximately $28.3 million because of
additional capital contributions of $36.8 million by HEI to ASB since the
acquisition, exclusive of capital contributions made in connection with ASB's
acquisition of most of the Hawaii operations of BoA. ASB is subject to OTS
regulations on dividends and other distributions applicable to financial
institutions regulated by the OTS.

ASB's earnings depend primarily on its net interest income--the difference
between the interest income earned on interest-earning assets (loans receivable,
mortgage-backed securities and investments) and the interest expense incurred on
interest-bearing liabilities (deposit liabilities and borrowings, including
borrowings from the Federal Home Loan Bank (FHLB) of Seattle).

The Deposit Insurance Funds Act of 1996 authorized a one-time deposit-insurance
premium assessment by the Federal Deposit Insurance Corporation (FDIC) of 65.7
cents per $100 of deposits insured by the Savings Association Insurance Fund
(SAIF) and held as of March 31, 1995. ASB's assessment was $8.3 million after
tax and was accrued in September 1996. The assessment resulted in a reduction of
ASB's deposit-insurance premiums from 23 cents to 6.48 cents per $100 of
deposits, effective January 1, 1997. With the reduction in deposit-insurance
premiums, ASB's annual after-tax savings was approximately $2 million for 1997.

For additional information about ASB, including ASB's acquisition of most of the
Hawaii operations of BoA in December 1997, see the "Savings Bank" sections under
HEI's MD&A, HEI's Quantitative and Qualitative Disclosures About Market Risk and
Note 3 to HEI's Consolidated Financial Statements.

Asset/liability management

Interest rate sensitivity refers to the relationship between market interest
rates and net interest income resulting from the repricing of interest-earning
assets and interest-bearing liabilities. Interest rate risk arises when an
interest-earning asset matures or when its interest rate changes in a time frame
different from that of the supporting interest-bearing liability. Maintaining an
equilibrium between rate sensitive interest-earning assets and interest-bearing
liabilities will reduce some interest rate risk but it will not guarantee a
stable net interest spread because yields and rates may change simultaneously or
at different times and such changes may occur in differing increments. Market
rate fluctuations could materially 

                                       21
<PAGE>
 
affect the overall net interest spread even if interest-earning assets and
interest-bearing liabilities were perfectly matched. The difference between the
amounts of interest-earning assets and interest-bearing liabilities that reprice
during a given period is called "gap." An asset-sensitive position or "positive
gap" exists when more assets than liabilities reprice within a given period; a
liability-sensitive position or "negative gap" exists when more liabilities than
assets reprice within a given period. A positive gap generally produces more net
interest income in periods of rising interest rates and a negative gap generally
produces more net interest income in periods of falling interest rates.

As of December 31, 1998, the gap in the near term (0-6 months) was a negative
0.6% of total assets as compared to a cumulative one-year positive gap position
of 0.8% of total assets. The difference between the near-term and one-year
positive gap positions is primarily due to reduced amounts of repricing of
interest-bearing liabilities such as in short-term certificates of deposits and
other borrowings to support investment activities. The following table shows
ASB's interest rate sensitivity at December 31, 1998:

Other income

In addition to net interest income, ASB has various sources of other income,
including fee income from servicing loans, fees on deposit accounts, rental
income from premises and other income. Other income totaled approximately $29.2
million in 1998, $16.5 million in 1997 and $15.7 million in 1996. The increase
in other income during 1998 was primarily due to an increase in fee income from
deposits and other branch services.

Lending activities

General.  Loans and mortgage-backed securities of $4.9 billion represented 86.7%
of total assets at December 31, 1998, compared to $4.9 billion, or 88.3%, and
$3.3 billion, or 93.1%, at December 31, 1997 and 1996, respectively. ASB's net
loan and mortgage-backed securities portfolio increase in 1997 was primarily due
to the purchase of $0.9 billion of Hawaii-based BoA loans and the purchase of
$0.8 billion in mortgage-backed securities, primarily in anticipation of the BoA
acquisition. ASB's loan portfolio consists primarily of conventional residential
mortgage loans which are not insured by the Federal Housing Administration nor
guaranteed by the Veterans Administration.

(1)  Includes renegotiated loans.

Origination, purchase and sale of loans.  Generally, loans originated and
purchased by ASB are secured by real estate located in Hawaii. As of December
31, 1998, approximately $87.8 million of loans purchased from other lenders were
secured by properties located in the continental United States. For additional
information, including information concerning the geographic distribution of
ASB's mortgage-backed securities portfolio and the geographic concentration of
credit risk, see Note 14 to HEI's Consolidated Financial Statements.

The amount of loans originated during 1998, 1997, 1996, 1995 and 1994 were $631
million, $327 million, $498 million, $382 million and $523 million,
respectively. The demand for loans is primarily dependent on the Hawaii real
estate market and loan refinancing activity. The increases in loans originated
in 1998 from 1997 and in 1996 from 1995 were due primarily to higher
refinancings. The decreases in loans originated in 1997 from 1996 and in 1995
from 1994 were due in part to the slow Hawaii real estate market.

Residential mortgage lending.  ASB is permitted to lend up to 100% of the
appraised value of the real property securing a loan. Its general policy is to
require private mortgage insurance when the loan-to-value ratio of the property
exceeds 80% of the lower of the appraised value or purchase price at
origination. For nonowner-occupied residential properties, the loan-to-value
ratio may not exceed 90% of the lower of the appraised value or purchase price
at origination.

Construction and development lending.  ASB provides both fixed and adjustable
rate loans for the construction of one-to-four residential unit and commercial
properties. Construction and development financing generally involves a higher
degree of credit risk than long-term financing on improved, occupied real
estate. Accordingly, all construction and development loans are priced higher
than loans secured by completed structures. ASB's underwriting, monitoring and
disbursement practices with 

                                       26
<PAGE>
 
respect to construction and development financing are designed to ensure
sufficient funds are available to complete construction projects. As of December
31, 1998, 1997 and 1996, construction and development loans represented 1.1%,
1.0% and 1.5%, respectively, of ASB's gross loan portfolio. See "Loan portfolio
risk elements."

Multifamily residential and commercial real estate lending.  Permanent loans
secured by multifamily properties (generally apartment buildings), as well as
commercial and industrial properties (including office buildings, shopping
centers and warehouses), are originated by ASB for its own portfolio as well as
for participation with other lenders. In 1998, 1997 and 1996, loans on these
types of properties accounted for approximately 2.8%, 2.7% and 3.2%,
respectively, of ASB's total mortgage loan originations. The objective of
commercial real estate lending is to diversify ASB's loan portfolio to include
sound, income-producing properties.

Consumer lending.  ASB offers a variety of secured and unsecured consumer loans.
Loans secured by deposits are limited to 90% of the available account balance.
ASB also offers VISA cards, automobile loans, general purpose consumer loans,
second mortgage loans, home equity lines of credit, checking account overdraft
protection and unsecured lines of credit. In 1998, 1997 and 1996, loans of these
types accounted for approximately 3.1%, 9.0% and 8.0%, respectively, of ASB's
total loan originations. In 1998, consumer loan originations decreased primarily
due to the increased amount of first mortgage refinancings which caused less
demand for second mortgage loans and home equity lines of credit.

Corporate banking/commercial lending.  ASB is authorized to make both secured
and unsecured corporate banking loans to business entities. This lending
activity is designed to diversify ASB's asset structure, shorten maturities,
provide rate sensitivity to the loan portfolio and attract business checking
deposits. ASB acquired $56.9 million of corporate banking loans from BoA in 1997
and has developed a larger corporate banking department. As of December 31,
1998, 1997 and 1996, corporate banking loans represented 2.8%, 2.8% and 0.8%,
respectively, of ASB's total net loan portfolio.

Loan origination fee and servicing income.  In addition to interest earned on
loans, ASB receives income from servicing loans, for late payments and from
other related services. Servicing fees are received on loans originated and
subsequently sold by ASB through a securitization process and also on loans for
which ASB acts as collection agent on behalf of third-party purchasers. ASB
acquired the servicing rights for approximately $305 million of residential
loans from BoA in 1997.

ASB generally charges the borrower at loan settlement a loan origination fee
ranging from 2% to 3% of the amount borrowed. See the "Loan origination and
commitment fees" section in Note 1 to HEI's Consolidated Financial Statements.

Loan portfolio risk elements.  When a borrower fails to make a required payment
on a loan and does not cure the delinquency promptly, the loan is classified as
delinquent. If delinquencies are not cured promptly, ASB normally commences a
collection action, including foreclosure proceedings in the case of secured
loans. In a foreclosure action, the property securing the delinquent debt is
sold at a public auction in which ASB may participate as a bidder to protect its
interest. If ASB is the successful bidder, the property is classified in a real
estate owned account until it is sold. ASB's real estate acquired in settlement
of loans represented 0.10% of total assets at December 31, 1998 and 0.07% of
total assets at December 31, 1997 and 1996.

In addition to delinquent loans, other significant lending risk elements
include: (1) loans which accrue interest and are over 90 days past due as to
principal or interest, (2) loans accounted for on a nonaccrual basis (nonaccrual
loans), and (3) loans on which various concessions are made with respect to
interest rate, maturity, or other terms due to the inability of the borrower to
service the obligation under the original terms of the agreement (renegotiated
loans). ASB had no loans which were over 90 days past due on which interest was
being accrued as of the dates presented in the table below. The level of
nonaccrual and renegotiated loans represented 3.1%, 2.4%, 2.5%, 1.7% and 1.4%,
of ASB's total net

                                       27

loans outstanding at December 31, 1998, 1997, 1996, 1995 and 1994, respectively.

</TABLE>

ASB's policy generally is to place mortgage loans on a nonaccrual status
(interest accrual is suspended) when the loan becomes more than 90 days past due
or on an earlier basis when there is a reasonable doubt as to its
collectability. Loans on nonaccrual status amounted to $85.5 million (2.6% of
total loans), $71.8 million (2.3% of total loans), $47.1 million (2.3% of total
loans), $27.1 million (1.6% of total loans) and $23.8 million (1.3% of total
loans) at December 31, 1998, 1997, 1996, 1995 and 1994, respectively.

Since 1994, the increases in nonaccrual loans were a result of Hawaii's weak
economy. In 1996, the $20.0 million increase in nonaccrual loans was
attributable primarily to a single real estate developer with residential,
commercial real estate and commercial loans totaling approximately $16.5 million
that were restructured during 1996. In 1997, the $24.8 million increase in
nonaccrual loans included a $13.1 million increase in nonaccruing, smaller
balance residential loans and a $10.1 million increase in nonaccruing, income
property real estate loans. In 1998, the $13.7 million increase in nonaccrual
loans was primarily due to a $10.3 million increase in nonaccruing, smaller
balance residential loans.

In 1998, ASB renegotiated two income property loans which are currently making
timely monthly payments of principal and interest.

Allowance for loan losses.  The provision for loan losses is dependent upon
management's evaluation as to the amount required to maintain the allowance for
loan losses at a level considered appropriate in relation to the risk of future
losses inherent in the loan portfolio. While management attempts to use the best
information available to make evaluations, future adjustments may be necessary
as circumstances change and additional information becomes available.

</TABLE>

ASB's ratio of provisions for loan losses during the year to average loans
outstanding was 0.45%, 0.32%, 0.41%, 0.28% and 0.21% for the years ended
December 31, 1998, 1997, 1996, 1995 and 1994, respectively. In 1997, a
nonspecific allowance for loan losses amounting to approximately $6.4 million
was recorded in assigning acquisition cost to the loans receivable acquired from
BoA. In 1998, 1997, 1996 and 1995, to establish additional specific loss
allowances and in response to a rising trend of delinquencies caused by Hawaii's
weak economy, ASB increased its loss reserve by $9.8 million, $4.3 million, $6.3
million and  $4.1 million, respectively.

Investment activities

In recent years, ASB's investment portfolio consisted primarily of stock of the
FHLB of Seattle, federal agency obligations and mortgage-backed securities. In
response to the then increasing interest rate environment, management decided in
1994 to liquidate ASB's portfolio of securities held for trading and the
liquidation was completed in October 1994. ASB recognized a one-time gain on
sale of trading account securities in 1995 in accordance with implementation
guidance provided in a Financial Accounting Standards Board special report. ASB
did not maintain a portfolio of securities held for trading during 1996, 1997 or
1998.

ASB's investment portfolio, excluding mortgage-backed securities to be held-to-
maturity, consisted of a $43.0 million investment in U.S. Treasury securities
and a $68.6 million investment in FHLB stock as of December 31, 1998. Investment
in FHLB stock amounted to $63.5 million and $37.5 million as of December 31,
1997 and 1996, respectively. The weighted-average rate on investments during
1998, 1997 and 1996 was 6.23%, 7.57% and 7.80%, respectively. The amount that
ASB is required to invest in FHLB stock is determined by regulatory
requirements. See "Regulation and other matters--Savings bank regulation--
Federal Home Loan Bank System."

Deposits and other sources of funds

General.  Deposits traditionally have been the principal source of ASB's funds
for use in lending, meeting liquidity requirements and making investments. ASB
also derives funds from receipt of interest and principal on outstanding loans
receivable and mortgage-backed securities, borrowings from the FHLB of Seattle,
securities sold under agreements to repurchase and other sources. ASB borrows on
a short-term basis to compensate for seasonal or other reductions in deposit
flows. ASB also may borrow on a longer-term basis to support expanded lending or
investment activities. In the last few years, securities sold under agreements
to repurchase and advances from the FHLB have become significant sources of
funds as the demand for deposits has decreased. Using higher cost sources of
funds puts downward pressure on ASB's net interest income.

                                       29
<PAGE>
 
Deposits.  ASB's deposits are obtained primarily from residents of Hawaii. In
1998, ASB had average deposits of $3.9 billion, with a net savings outflow of
$174.1 million, excluding interest credited to deposit accounts, compared to a
net savings inflow in 1997 of $21.9 million, excluding $1.7 billion in deposits
assumed from BoA. In 1996, ASB had a net savings outflow of $152 million,
excluding interest credited to deposit accounts. The net savings outflows in
1998 and 1996 were partly due to competition from the equity market and
management's decision not to pursue high-priced certificates of deposits. In the
three years ended December 31, 1998, ASB had no deposits placed by or through a
broker.

The following table illustrates the distribution of ASB's average deposits and
average daily rates by type of deposit for the years indicated. Average balances
for a year have been calculated using the average of month-end balances during
the year, with the average balances for 1997 reflecting the effect of the
acquisition of most of BoA's Hawaii operations on December 6, 1997.

Borrowings.  ASB obtains advances from the FHLB of Seattle provided certain
standards related to creditworthiness have been met. Advances are secured under
a blanket pledge of the common stock ASB owns in the FHLB, mortgage-backed
securities and certain notes held by ASB and the mortgages securing them. FHLB
advances generally are available to meet seasonal and other withdrawals of
deposit accounts, to expand lending and to assist in the effort to improve asset
and liability management. FHLB advances are made pursuant to several different
credit programs offered from time to time by the FHLB of Seattle.

At December 31, 1998, 1997 and 1996, advances from the FHLB amounted to $806
million, $736 million and $684 million, respectively. The weighted-average rates
on the advances from the FHLB outstanding at December 31, 1998, 1997 and 1996
were 6.17%, 6.26% and 6.42%, respectively. The maximum amount outstanding at any
month-end during 1998, 1997 and 1996 was $831 million, $941 million and $691
million, respectively. Advances from the FHLB averaged $779 million, $701
million and $560 million during 1998, 1997 and 1996, respectively, and the
approximate weighted-average rate thereon was 6.25%, 6.32% and 6.49%,
respectively. During 1996, the increase in advances supported investment
activities as management decided not to pursue high-priced certificates of
deposits. During 1997, increased advances from the FHLB were needed to support
investment activities.  In anticipation of the BoA acquisition, ASB acquired
approximately $0.8 billion in mortgage-backed securities which were temporarily
funded in part by advances from the FHLB. During 1998, increased advances were
needed to support loan originations.

At December 31, 1998 and 1997, securities sold under agreements to repurchase
consisted of mortgage-backed securities sold to brokers/dealers under fixed-
coupon agreements. The agreements are treated as financings and the obligations
to repurchase securities sold are reflected as a liability in the consolidated
balance sheets. The dollar amount of securities underlying the agreements
remains in the asset accounts. At December 31, 1998, 1997 and 1996, the entire
outstanding amounts under these agreements of $515 million (including accrued
interest of $1.5 million), $375 million (including accrued interest of $0.9
million) and $480 million (including accrued interest of $1.6 million),
respectively, were to purchase identical securities. The weighted-average rates
on securities sold under agreements to repurchase outstanding at December 31,
1998, 1997 and 1996 were 5.36%, 5.71% and 5.50%, respectively. The maximum
amount outstanding at any month-end during 1998, 1997 and 1996 was $551 million,
$765 million and $480 million, respectively. Securities sold under agreements to
repurchase averaged $470 million, $560 million and $463 million during 1998,
1997 and 1996, respectively, and the approximate weighted-average interest rate
thereon was 5.53%, 5.58% and 5.65%, respectively. During 1997, increased
securities sold under agreements to repurchase were needed to temporarily fund
the purchase of mortgage-backed and investment securities in anticipation of the
BoA acquisition.

Other borrowings, as of December 31, 1998 and 1997, represented cash management
repurchase transactions. ASB sweeps selected commercial customers' excess
deposit balances into an overnight repurchase transaction.

The following table sets forth information concerning ASB's advances from FHLB
and other borrowings at the dates indicated:

Competition

The primary factors in competing for deposits are interest rates, the quality
and range of services offered, marketing, convenience of locations, hours and
perceptions of the institution's financial soundness and safety. Competition for
deposits comes primarily from other savings institutions, commercial banks,
credit unions, money market and mutual funds and other investment alternatives.
In Hawaii, there were 3 thrifts, 13 FDIC-insured banks and 113 credit unions at
September 30, 1998. Additional competition for deposits comes from various types
of corporate and government borrowers, including insurance companies. To meet
the competition, ASB offers a variety of savings and checking accounts at
competitive rates, convenient business hours, convenient branch locations with
interbranch deposit and withdrawal privileges at each branch and approximately
150 convenient automated teller machines. ASB also conducts advertising and
promotional campaigns.

The primary factors in competing for first mortgage and other loans are interest
rates, loan origination fees and the quality and range of lending services
offered. Competition for origination of first mortgage loans comes primarily
from other savings institutions, mortgage banking firms, commercial banks,
insurance companies and real estate investment trusts. ASB believes that it is
able to compete for such loans primarily through the interest rates and loan
fees it charges, the type of mortgage loan programs it offers and the efficiency
and quality of the services it provides its borrowers and the real estate
business community.

In recent years, there's been significant bank and thrift merger activity in
Hawaii. Management cannot predict the impact, if any, of these mergers on the
Company's future competitive position, results of operations, financial
condition or liquidity.

Credit Union Developments.  The 1934 Federal Credit Union Act states that credit
union membership "shall be limited to groups having a common bond of occupation
or association" or to groups in a well-defined geographical area. In 1982, the
National Credit Union Administration expanded its definition of "common bond" to
allow "multiple common bonds"--i.e., small businesses that lacked enough workers
to form their own credit unions were allowed to join existing credit unions, so
long as each group of employees had its own "bond." Government officials
estimate that rule allowed credit unions to add approximately 15 million people
to their membership rolls. In February 1998, the Supreme Court decided that this
expanded definition of "common bond" was impermissible, holding that the 1934
law required all members of a credit union to share a single common bond. In
August 1998, the Credit Union Membership Access Act became law, which, among
other things, amended the 1934 law to retroactively authorize credit union
membership based on multiple common bonds, as long as each of the relevant
groups has (with some exceptions) fewer than 3,000 members. The Credit Union
Membership Access Act also facilitates the ability of insured credit unions to
convert to mutual savings banks or savings associations, and requires that
insured credit unions meet capital standards similar to those enacted for banks
and thrifts in 1991.

In December 1998, the National Credit Union Administration voted to adopt final
rules to implement the Credit Union Membership Access Act. The new rules appear
to favor the creation of larger credit unions by facilitating the merger of
credit unions with fewer than 3,000 members. Several members of the House
Banking Committee criticized the new rules as disregarding Congressional intent
and indicated further legislation is possible. The American Bankers Association
has also filed a suit challenging the new rules. It is too early to evaluate
whether these developments will result in increased competition for ASB by
credit unions.

Freight transportation -- Hawaiian Tug & Barge Corp. and Young Brothers, Limited
- --------------------------------------------------------------------------------

General

HTB and its wholly owned subsidiary, YB, were acquired by HEI in 1986. A
substantial portion of the state's commodities are imported. HTB provides marine
transportation services in Hawaii and the Pacific area, including charter tug
and barge and harbor tug operations. YB, which is a regulated interisland cargo
carrier, transports general freight and containerized cargo by barge on a
regular schedule between all major ports in Hawaii. YB moved 3.6 million revenue
tons of cargo between the islands in 1998, compared to 3.5 million revenue tons
in 1997.

YB has a nonexclusive Certificate of Public Convenience and Necessity from the
PUC to operate as an intrastate common carrier by water. The Certificate will
remain in effect for an indefinite period unless suspended or terminated by the
PUC. YB encounters competition from, among others, interstate carriers and
unregulated contract carriers.

YB rates

YB generally must accept for transport all cargo offered. YB rates and charges
must be approved by the PUC and the PUC has broad discretion in its regulation
of the rates charged by YB.

See the "Other" section of HEI's MD&A for additional information about YB's rate
increases.

HEI Investment Corp.
- --------------------

HEIIC was incorporated in May 1984 primarily to make passive, tax-advantaged
investments in corporate securities and other long-term investments. HEIIC is
not an "investment company" under the Investment Company Act of 1940 and has no
direct employees.

HEIIC's long-term investments consist primarily of investments in leveraged
leases. HEIIC has a 15% ownership interest in an 818-MW coal-fired generating
unit in Georgia, which is subject to a leveraged 

                                       32
<PAGE>
 
lease agreement. In 1987, HEIIC purchased commercial buildings on leasehold
properties located in the continental United States, along with the related
lease rights and obligations. These leveraged, purchase-leaseback investments
included two major buildings housing operations of Hershey Foods in Pennsylvania
and six supermarkets leased to The Kroger Co. in various states. In 1995, HEIIC
sold one of the six supermarkets to the lessee pursuant to the provisions of the
leveraged lease agreement and recorded a net loss of $1.3 million on the sale.
No significant new investments are currently planned by HEIIC.

HEI Power Corp.
- ---------------

HEIPC was formed in March 1995 and its subsidiaries have been and will be formed
from time to time to pursue independent power and integrated energy services
projects in Asia and the Pacific (collectively, the HEIPC Group).

The HEIPC Group is actively pursuing other projects in Asia and the Pacific. The
success of any project undertaken by the HEIPC Group in foreign countries will
be dependent on many factors, including the economic, political, technological,
regulatory and logistical circumstances surrounding each project and the
location of the project. Due to political or regulatory actions or other
circumstances, projects may be delayed or even prohibited. There is no assurance
that any project undertaken by HEIPC will be successfully completed or that
HEIPC's investment in any such project will not be lost, in whole or in part.

For a discussion of the HEIPC Group, its operating losses, projects, investments
and commitments, see the "Other" section in HEI's MD&A and the "China project"
section of Note 17 to HEI's Consolidated Financial Statements.

Discontinued operations
- -----------------------

For information concerning the Company's discontinued property and casualty
insurance operations formerly conducted by HIG and its discontinued residential
real estate development business conducted by MPC and its subsidiaries, see Note
15 to HEI's Consolidated Financial Statements. Also see Item 3, "Legal
proceedings--Discontinued operations."

Regulation and other matters
- ----------------------------

Holding company regulation

HEI and HECO are holding companies within the meaning of the Public Utility
Holding Company Act of 1935 (1935 Act). However, under current rules and
regulations, they are exempt from the comprehensive regulation of the SEC under
the 1935 Act except for Section 9(a)(2) (relating to the acquisition of
securities of other public utility companies) through compliance with certain
annual filing requirements under the 1935 Act for holding companies which own
utility businesses that are intrastate in character. The exemption afforded HEI
and HECO may be revoked if the SEC finds that such exemption "may be detrimental
to the public interest or the interest of investors or consumers." HEI and HECO
may own or have interests in foreign utility operations without adversely
affecting this exemption so long as the requirements of other exemptions under
the 1935 Act are satisfied. HEI has obtained the PUC certification which is a
prerequisite to obtaining an exemption for foreign utility operations and to the
Company's maintenance of its exemption under the 1935 Act if it acquires such
ownership interests. In 1996, HEI filed with the SEC a Form U-57, "Notification
of Foreign Utility Company Status," on behalf of HEI Power Corp. Guam (for the
HEIPC Group's Guam project). In 1998, HEI filed two Forms U-57 on behalf of
Baotou Tianjiao Power Co., Ltd. (for the HEIPC Group's China project) and on
behalf of Cagayan Electric Power and Light Co., Inc. (for the HEIPC Group's
investment in the Philippines).

Legislation has been introduced in Congress in the past that would repeal the
1935 Act leaving the regulation of utility holding companies to be governed by
other federal and state laws. Management cannot predict if this legislation will
be enacted or the final form it might take.

HEI is subject to an agreement entered into with the PUC (the PUC Agreement)
when HECO became a wholly owned subsidiary of HEI. The PUC Agreement, among
other things, requires HEI to provide the 

                                       33
<PAGE>
 
PUC with periodic financial information and other reports concerning
intercompany transactions and other matters. It prohibits the electric utilities
from loaning funds to HEI or its nonutility subsidiaries and from redeeming
common stock of the electric utility subsidiaries without PUC approval. Further,
the PUC could limit the ability of the electric utility subsidiaries to pay
dividends on their common stock. See "Restrictions on dividends and other
distributions" and "Electric utility regulation" (regarding the PUC review of
the relationship between HEI and HECO).

As a result of the acquisition of ASB, HEI and HEIDI are subject to OTS
registration, supervision and reporting requirements as savings and loan holding
companies.

In the event the OTS has reasonable cause to believe that the continuation by
HEI or HEIDI of any activity constitutes a serious risk to the financial safety,
soundness, or stability of ASB, the OTS is authorized under the Home Owners'
Loan Act of 1933, as amended, to impose certain restrictions in the form of a
directive to HEI and any of its subsidiaries, or HEIDI and any of its
subsidiaries. Such possible restrictions include limiting (i) the payment of
dividends by ASB; (ii) transactions between ASB, HEI or HEIDI, and the
subsidiaries or affiliates of ASB, HEI or HEIDI; and (iii) the activities of ASB
that might create a serious risk that the liabilities of HEI and its other
affiliates, or HEIDI and its other affiliates, may be imposed on ASB.
Theoretically, this authority would allow the OTS to prohibit dividends, limit
affiliate transactions or otherwise restrict activities as a result of losses
suffered by HEI, HEIDI or their other subsidiaries, and thus conceivably may be
an indirect means of limiting affiliations between ASB and affiliates engaged in
nonfinancial activities. See "Restrictions on dividends and other
distributions."

OTS regulations also generally prohibit savings and loan holding companies and
their nonthrift subsidiaries from engaging in activities other than those which
are specifically enumerated in the regulations. Such restrictions, if applicable
to HEI and HEIDI, would significantly limit the kinds of activities in which HEI
and HEIDI and their subsidiaries may engage. However, the OTS regulations
provide for an exemption which is available to HEI and HEIDI if ASB satisfies
the qualified thrift lender (QTL) test discussed below. See "Savings bank
regulation--Qualified thrift lender test." ASB must continue to meet the
qualified thrift lender test in order to avoid restrictions on the activities of
HEI and HEIDI and their subsidiaries which could result in a need to divest ASB.
ASB met the QTL test at all times during 1998.

HEI and HEIDI are prohibited, directly or indirectly, or through one or more
subsidiaries, from (i) acquiring control of, or acquiring by merger or purchase
of assets, another insured institution or holding company thereof, without prior
written OTS approval; (ii) acquiring more than 5% of the voting shares of
another savings association or savings and loan holding company which is not a
subsidiary; or (iii) acquiring or retaining control of a savings association not
insured by the FDIC. No director or officer of HEI or HEIDI, or person
beneficially owning more than 25% of such holding company's voting shares, may,
except with the prior approval of the OTS, (a) also serve as director, officer,
or employee of any insured institution or (b) acquire control of any savings
association not a subsidiary of such holding company. On May 26, 1997, ASB
entered into a Purchase and Assumption Agreement with BoA to assume
substantially all of the Hawaii deposit liabilities of BoA and acquire most of
its Hawaii branches and certain of its Hawaii-based loans.  On October 29, 1997,
the OTS approved the transaction and the transaction closed effective December
6, 1997.

Restrictions on dividends and other distributions

HEI is a legal entity separate and distinct from its various subsidiaries. As a
holding company with no significant operations of its own, the principal sources
of its funds are dividends or other distributions from its operating
subsidiaries, borrowings and sales of equity. The rights of HEI and,
consequently, its creditors and shareholders, to participate in any distribution
of the assets of any of its subsidiaries is subject to the prior claims of the
creditors and preferred stockholders of such subsidiary, except to the extent
that claims of HEI in its capacity as a creditor are recognized.

The abilities of certain of HEI's subsidiaries to pay dividends or make other
distributions to HEI are subject to contractual and regulatory restrictions.
Under the PUC Agreement, in the event that the consolidated common stock equity
of the electric utility subsidiaries falls below 35% of total electric 

                                       34
<PAGE>
 
utility capitalization, the electric utility subsidiaries would be restricted,
unless they obtained PUC approval, in their payment of cash dividends to 80% of
the earnings available for the payment of dividends in the current fiscal year
and preceding five years, less the amount of dividends paid during that period.
The PUC Agreement also provides that the foregoing dividend restriction shall
not be construed to relinquish any right the PUC may have to review the dividend
policies of the electric utility subsidiaries. The consolidated common stock
equity of HEI's electric utility subsidiaries was 49% of their total
capitalization (including the current maturities of long-term debt and preferred
stock sinking fund requirements due within one year but excluding short-term
borrowings) as of December 31, 1998. As of December 31, 1998, HECO and its
subsidiaries had net assets of $787 million, of which approximately $433 million
were not available for transfer to HEI without regulatory approval.

The ability of ASB to make capital distributions to HEI and other affiliates is
restricted under federal law. Subject to a limited exception for stock
redemptions that do not result in any decrease in ASB's capital and would
improve ASB's financial condition, ASB is prohibited from declaring any
dividends, making any other capital distribution, or paying a management fee to
a controlling person if, following the distribution or payment, ASB would be
deemed to be undercapitalized, significantly undercapitalized or critically
undercapitalized. See "Savings bank regulation--Prompt corrective action."

As a Tier-1 institution (one that meets its capital requirements and has not
been notified by the OTS that it is in need of more than normal supervision),
ASB may make capital distributions in amounts up to one-half of ASB's surplus
capital ratio (the amount of its capital in excess of its capital requirement)
at the beginning of a calendar year, plus its year-to-date net income for that
calendar year. ASB, as a Tier-1 institution, may exceed the foregoing limits if
ASB provides a thirty-day advance notice to the OTS and receives no objection
within thirty days. However, even in the case of distributions within the
permissible limits, a thirty day advance notice to the OTS is required.

HEI and its subsidiaries are also subject to debt covenants, preferred stock
resolutions and the terms of guarantees that could limit their respective
abilities to pay dividends. The Company does not expect that the regulatory and
contractual restrictions applicable to HEI or its direct and indirect
subsidiaries will significantly affect the operations of HEI or its ability to
pay dividends on its common stock.

Electric utility regulation

The PUC regulates the rates, issuance of securities, accounting and certain
other aspects of the operations of HECO and its electric utility subsidiaries.
See the previous discussion under "Electric utility--Rates" and the "Regulation
of electric utility rates" and "Recent rate requests" sections in HECO's MD&A.

The PUC has ordered the electric utility subsidiaries to develop plans for the
integration of demand-side and supply-side resources available to meet consumer
energy needs efficiently, reliably and at the lowest reasonable cost. See the
previous discussion under "Electric utility--Integrated Resource Planning and
requirements for additional generating capacity."

In March 1995, the PUC opened a generic docket to investigate whether Hawaii
public utilities should be allowed to establish property damage reserves to
recover the cost of damage to their facilities and equipment caused by
catastrophic disasters, and in March 1998 decided that such reserves should not
be established. See "Property damage reserve" in HECO's MD&A. Management cannot
predict how the PUC might apportion the responsibility for restoration costs
with respect to any uninsured catastrophic losses that HECO or its subsidiaries
may incur in the future.

On December 30, 1996, the PUC issued an order instituting a proceeding to
identify and examine the issues surrounding electric competition and to
determine the impact of competition on the electric utility infrastructure in
Hawaii. See the previous discussion under "Electric utility--Competition."

On March 10, 1997, the PUC issued a show cause order to HECO requesting
information to assist the PUC in determining if it should reduce HECO's rates
and require HECO to refund any excess earnings to its ratepayers.  See the
previous discussion under "Electric utility--PUC Show Cause Order."

                                       35
<PAGE>
 
Any adverse decision or policy made or adopted by the PUC, or any prolonged
delay in rendering a decision, could have a material adverse effect on
consolidated HECO's and the Company's financial condition, results of operations
or liquidity.

Certain transactions between HEI's electric public utility subsidiaries (HECO,
MECO and HELCO) and HEI and affiliated interests, are subject to regulation by
the PUC. All contracts (including summaries of unwritten agreements), made on or
after July 1, 1988 of $300,000 or more in a calendar year for management,
supervisory, construction, engineering, accounting, legal, financial and similar
services and for the sale, lease or transfer of property between a public
utility and affiliated interests must be filed with the PUC to be effective, and
the PUC may issue cease and desist orders if such contracts are not filed. All
such affiliated contracts for capital expenditures (except for real property)
must be accompanied by comparative price quotations from two nonaffiliates,
unless the quotations cannot be obtained without substantial expense. Moreover,
all transfers of $300,000 or more of real property between a public utility and
affiliated interests require the prior approval of the PUC and proof that the
transfer is in the best interest of the public utility and its customers. If the
PUC, in its discretion, determines that an affiliated contract is unreasonable
or otherwise contrary to the public interest, the utility must either revise the
contract or risk disallowance of the payments for rate-making purposes. In rate-
making proceedings, a utility must also prove the reasonableness of payments
made to affiliated interests under any affiliated contract of $300,000 or more
by clear and convincing evidence. An "affiliated interest" is defined by statute
and includes officers and directors of a public utility, every person owning or
holding, directly or indirectly, 10% or more of the voting securities of a
public utility, and corporations which have in common with a public utility more
than one-third of the directors of that public utility.

In January 1993, to address community concerns expressed at the time, HECO
proposed that the PUC initiate a review of the relationship between HEI and HECO
and the effects of that relationship on the operations of HECO. The PUC opened a
docket and initiated such a review to determine whether the HEI-HECO
relationship, HEI's diversified activities, and HEI's policies, operations and
practices had resulted in or were having any negative effects on HECO, its
electric utility subsidiaries and ratepayers. In May 1994, the PUC selected a
consultant, Dennis Thomas and Associates, to perform the review. In early 1995,
Dennis Thomas and Associates issued its report (the Thomas report) to the PUC.
The Thomas report concluded that "on balance, diversification has not hurt
electric ratepayers." Other major findings were that (1) no utility assets have
been used to fund HEI's nonutility investments or operations, (2) management
processes within the electric utilities operate without interference from HEI
and (3) HECO's access to capital did not suffer as a result of HEI's involvement
in nonutility activities and that diversification did not permanently raise or
lower the cost of capital incorporated into the rates paid by HECO's utility
customers. The Thomas report also included a number of recommendations, most of
which the Company has implemented. In December 1996, the PUC issued an order
that adopted the Thomas report in its entirety, ordered HECO to continue to
provide the PUC with status reports on its compliance with the PUC agreement
(pursuant to which HEI became the holding company of HECO) and closed the
investigation and proceeding. The PUC has not required that the Company
implement all of the recommendations in the Thomas report. In the order, the PUC
also stated that it adopted the recommendation of the DOD that HECO, MECO and
HELCO present a comprehensive analysis of the impact that the holding company
structure and investments in nonutility subsidiaries have on a case-by-case
basis on the cost of capital to each utility in future rate cases and remove
such effects from the cost of capital. In its most recent rate increase
application filed in the first quarter of 1998, MECO provided an affidavit of a
consultant retained by Dennis Thomas and Associates for the review. The
consultant stated that "the methodology used to establish the allowed rate of
return for electric utility operations inherently avoids any bias which might be
introduced by HEI's diversified activities," and further stated that the
findings of the comprehensive review conducted for the Thomas report with
respect to the availability and cost of capital to HEI and its utility
subsidiaries would not be expected to be materially different from those adopted
by the PUC in December 1996. See also "Holding company regulation."

HECO and its subsidiaries are not subject to regulation by the Federal Energy
Regulatory Commission under the Federal Power Act, except under Sections 210
through 212 (added by Title II of PURPA and amended by the Energy Policy Act of
1992), which permit the Federal Energy Regulatory Commission to order electric
utilities to interconnect with qualifying cogenerators and small power
producers, and to wheel power to other electric utilities. Title I of PURPA,
which relates to retail regulatory policies for electric utilities, also applies
to HECO and its subsidiaries. Title VII of the Energy Policy Act of 1992, which
creates "exempt wholesale generators" (EWGs) as a category that is exempt from
the 1935 Act and which addresses transmission access, also applies to HECO and
its subsidiaries. The Company cannot predict the extent to which cogeneration,
EWGs or transmission access will reduce its electrical loads, reduce its current
and future generating and transmission capability requirements or affect its
financial condition, results of operations or liquidity.

Because they are located in the State of Hawaii, HECO and its subsidiaries are
exempt by statute from limitations set forth in the Powerplant and Industrial
Fuel Act of 1978 on the use of petroleum as a primary energy source.

Savings bank regulation

ASB, a federally chartered savings bank, and its holding companies are subject
to the regulatory supervision of the OTS and, in certain respects, the FDIC. In
addition, ASB must comply with Federal Reserve Board reserve requirements and
OTS liquidity requirements. See "Liquidity and capital resources--Savings bank"
in HEI's MD&A.

Deposit insurance coverage.  The Federal Deposit Insurance Act, as amended by
Federal Deposit Insurance Corporation Insurance Act of 1991 (FDICIA), and
regulations promulgated by the FDIC, govern insurance coverage of deposit
amounts. Generally, the deposits maintained by a depositor in an insured
institution are insured to $100,000, with the amount of all deposits held by a
depositor in the same capacity (even if held in separate accounts) aggregated
for purposes of applying the $100,000 limit. For example, all deposits held in a
depositor's individual capacity are aggregated with each other but not with
deposits maintained by such depositor and his or her spouse in a qualifying
joint account, these latter joint deposits being separately insured to an
aggregate of $100,000. Similarly, an individual's interest in deposits at the
same institution in any combination of certain retirement accounts and employee
benefit plans will be added together and insured up to $100,000 in the
aggregate.

In addition, institutions that are "well capitalized" under the FDIC's prompt
corrective action regulations are generally able to provide "pass-through"
insurance coverage (i.e., insurance coverage that passes through to each
owner/beneficiary of the applicable deposit) for the deposits of most employee
benefit plans (i.e., $100,000 per individual participating, not $100,000 per
plan). Consequently, the FDIC deposit insurance regulations require financial
institutions to provide employee benefit plan depositors information, not
otherwise available, on the institution's capital category and whether "pass-
through" deposit insurance is available. As of December 31, 1998, ASB was "well
capitalized."

Federal thrift charter.  The legislative outlook for continued existence of the
federal thrift charter and the flexibility afforded thrift holding companies is
uncertain. If federal thrift charters were eliminated by legislation and ASB
obtained a bank charter, and if the legislation did not include grandfathering
provisions, HEI and its subsidiaries might become subject to the restrictions on
the permissible activities of a bank holding company. This could require HEI to
divest its interest in ASB. In 1998, financial modernization legislation, which
would have continued the federal thrift charter but restricted the permissible
activities of non-grandfathered thrift holding companies, passed the House of
Representatives in May 1998 and was reported favorably by the Senate Committee
on Banking, Housing, and Urban Affairs, in September 1998, but ultimately was
not enacted.

The new Congress, which convened in January 1999, is considering legislation to
address several of the issues that would have been covered had the 1998
legislation been enacted. Senate and House committee hearings on this proposed
legislation were held in February 1999, and the issue of the federal thrift
charter was the subject of extensive testimony and sharply differing opinions
during these hearings. At this time it is uncertain whether or in what form any
of these legislative proposals might ultimately be 

                                       37
<PAGE>
 
adopted or the extent to which the business of HEI or ASB might be affected by
any legislation that may be adopted.

For a discussion of the disparity in the deposit insurance assessment rates and
Financing Corporation assessment rates that ASB and other thrifts have paid in
relation to the rates that most commercial banks have paid and the special
assessment made by the FDIC on ASB and other thrifts in 1996 to provide adequate
funding for the SAIF and thereby permit a reduction in deposit insurance
assessment rates for thrifts and potential federal legislation affecting
financial institutions, see "Deposit insurance premiums and regulatory
developments" in Note 3 to HEI's Consolidated Financial Statements and page 39
of HEI's MD&A.

Capital requirements.  Under the Financial Institutions Reform, Recovery, and
Enforcement Act of 1989 (FIRREA), the OTS has set three capital standards for
thrifts, each of which must be no less stringent than those applicable to
national banks. As of December 31, 1998, ASB was in compliance with all of the
minimum standards with a core capital ratio of 5.3% (compared to a 3%
requirement), a tangible capital ratio of 5.3% (compared to a 1.5% requirement)
and risk-based capital ratio of 12.7% (based on risk-based capital of $322.2
million, $118.3 million in excess of the 8% requirement).

On March 2, 1999, the OTS issued final rules (effective April 1, 1999) revising
its risk-based capital standards as part of the effort by the OTS, FDIC, the
Board of Governors of the Federal Reserve System and the Office of the
Comptroller of the Currency to implement the provisions of the Riegle Community
Development and Regulatory Improvement Act of 1994, which requires these
agencies to work together to make uniform their respective regulations and
guidelines implementing common statutory or supervisory policies. The March 2,
1999 OTS revisions affect the risk-based capital treatment of:  (1) construction
loans on presold residential properties; (2) junior liens on 1- to 4-family
residential properties; (3) investments in mutual funds; and (4) the core
capital leverage ratio for institutions which do not have a composite rating of
"1" under the Uniform Financial Institution Rating System (i.e., the CAMELS
rating system). Under the new rules, an institution with a composite rating of
"1" under the CAMELS rating system must maintain core capital in an amount equal
to at least 3% of adjusted total assets. All other institutions must maintain a
minimum core capital of 4% of adjusted total assets, and higher capital ratios
may be required if warranted by particular circumstances. Had the new rules been
in place at December 31, 1998, ASB would have met the minimum core capital
requirement of 4% of adjusted total assets.

Affiliate transactions.  Significant restrictions apply to certain transactions
between ASB and its affiliates, including HEI and its direct and indirect
subsidiaries. FIRREA significantly altered both the scope and substance of such
limitations on transactions with affiliates and provided for thrift affiliate
rules similar to, but more restrictive than, those applicable to banks. For
example, ASB is prohibited from making any loan or other extension of credit to
an entity affiliated with ASB unless the affiliate is engaged exclusively in
activities which the Federal Reserve Board has determined to be permissible for
bank holding companies. There are also various other restrictions which apply to
certain transactions between ASB and certain executive officers, directors and
insiders of ASB. ASB is also barred from making a purchase of or any investment
in securities issued by an affiliate, other than with respect to shares of a
subsidiary of ASB.

Financial Derivatives and Interest Rate Risk.  In 1996, the Board of Governors
of the Federal Reserve System, the FDIC and the Office of the Comptroller of the
Currency issued a joint agency policy statement to bankers to provide guidance
on sound practices for managing IRR. However, the OTS has elected not to pursue
a standardized policy towards interest rate risk and investment and derivatives
activities with the other federal banking regulators.

On December 1, 1998, the OTS issued final rules on financial derivatives,
effective January 1, 1999. The OTS views these final rules as consistent with,
although more detailed than, the 1996 joint policy statement. The purpose of
these rules is to update the OTS rules on financial derivatives, which had
remained virtually unchanged for over 15 years.  Most significantly, the new
rules address interest rate swaps, a derivative instrument commonly used by
thrifts to manage interest rate risk which was not addressed in the prior OTS
rules. Currently ASB does not use interest rate swaps to manage interest rate

                                       38
<PAGE>
 
risk. Generally speaking, the new rules permit thrifts to engage in transactions
involving financial derivatives to the extent these transactions are otherwise
authorized under applicable law and are safe and sound.

The new rules have required ASB to revise its internal procedures for handling
financial derivative transactions, including increased involvement of the ASB
board of directors in authorizing and monitoring financial derivative
transactions. ASB has not yet determined whether the internal procedures
required by the new rules will materially affect its ability to continue to
carry out the type of financial derivative transactions it had previously
conducted.

Concurrently with the issuance of the new rules of financial derivative
transactions, the OTS also adopted on December 1, 1998 Thrift Bulletin 13a (TB
13a) for purpose of providing guidance on the management of interest rate risks,
investment securities and derivatives activities. TB 13a also describes the
guidelines OTS examiners will use in assigning the "Sensitivity to Market Risk"
component rating under the Uniform Financial Institutions Rating System (i.e.,
the CAMELS rating system). TB 13a became effective on December 1, 1998, and
replaces several previous Thrift Bulletins dealing with interest rate risk and
securities activities.

TB 13a updates the OTS's minimum standards for thrift institutions' interest
rate risk management practices with regard to board-approved risk limits and
interest rate risk measurement systems, and makes several significant changes.
First, under TB 13a, institutions no longer set board-approved limits or provide
measurements for the plus and minus 400 basis point interest rate scenarios
prescribed by the original TB 13. TB 13a also changes the form in which those
limits should be expressed. Second, TB 13a provides guidance on how the OTS will
assess the prudence of an institution's risk limits. Third, TB 13a raises the
size threshold above which institutions should calculate their own estimates of
the interest rate sensitivity of Net Portfolio Value (NPV) from $500 million to
$1 billion in assets. Fourth, TB 13a specifies a set of desirable features that
an institution's risk measurement methodology should utilize. Finally, TB 13a
provides an extensive discussion of "sound practices" for interest rate risk
management.

TB 13a also contains guidance on thrifts' investment and derivatives activities
by describing the types of analysis institutions should perform prior to
purchasing securities or financial derivatives. TB13a also provides guidelines
on the use of certain types of securities and financial derivatives for purposes
other than reducing portfolio risk.

Finally, TB 13a provides detailed guidelines for implementing part of the Notice
announcing the revision of the CAMELS rating system, published by the Federal
Financial Institutions Examination Council. That publication announced revised
interagency policies that, among other things, established the Sensitivity to
Market Risk component rating (the "S" rating). TB 13a provides quantitative
guidelines for an initial assessment of an institution's level of interest rate
risk. Examiners have broad discretion in implementing those guidelines. It also
provides guidelines concerning the factors examiners consider in assessing the
quality of an institution's risk management systems and procedures.

Adoption of the final TB 13a requires ASB to revise certain aspects of its
internal procedures, including increased involvement of the ASB board of
directors in the process of managing interest rate risk. ASB does not believe,
however, that the adoption of the final TB 13a will materially affect the
policies it has applied to manage interest rate risk.

Supervision.  The adoption of FDICIA in 1991 subjected the banking and thrift
industries to heightened regulation and supervision. FDICIA made a number of
reforms addressing the safety and soundness of the deposit insurance system,
supervision of domestic and foreign depository institutions and improvement of
accounting standards. FDICIA also limited deposit insurance coverage,
implemented changes in consumer protection laws and called for least-cost
resolution and prompt corrective action with regard to troubled institutions.

Pursuant to FDICIA, the federal banking agencies promulgated regulations which
may affect the operations of ASB and its holding companies. Such regulations
address, for example, standards for 

                                       39
<PAGE>
 
safety and soundness, real estate lending, accounting and reporting,
transactions with affiliates, and loans to insiders.

Prompt corrective action.  FDICIA establishes a statutory framework that is
triggered by the capital level of a savings association and subjects it to
progressively more stringent restrictions and supervision as capital levels
decline. The OTS rules implement the system of prompt corrective action. In
particular, the rules define the relevant capital measures for the categories of
"well capitalized", "adequately capitalized", "undercapitalized", "significantly
undercapitalized" and "critically undercapitalized".

A savings association that is undercapitalized or significantly undercapitalized
is subject to additional mandatory supervisory actions and a number of
discretionary actions if the OTS determines that any of the actions is necessary
to resolve the problems of the association at the least possible long-term cost
to the SAIF. A savings association that is critically undercapitalized must be
placed in conservatorship or receivership within 90 days, unless the OTS and the
FDIC concur that other action would be more appropriate.

Interest rates.  FDIC regulations restrict the ability of financial institutions
that are not "well capitalized" to offer interest rates on deposits that are
significantly higher than the rates offered by competing institutions. As of
December 31, 1998, ASB was "well capitalized" and thus not subject to these
interest rate restrictions.

Qualified thrift lender test.  FDICIA amended the QTL test provisions of FIRREA
by reducing the percentage of assets thrifts must maintain in "qualified thrift
investments" from 70% to 65%, and changing the computation period to require
that the percentage be reached on a monthly average basis in nine out of the
previous 12 months. The 1997 Omnibus Appropriations Act expanded the types of
loans that constitute "qualified thrift investments" from the traditional
category of housing-related loans to include small business loans, education
loans, loans made through credit card accounts, as well as a basket of other
consumer loans and certain other types of assets not to exceed 20% of total
assets. Savings associations that fail to satisfy the QTL test by not holding
the required percentage of "qualified thrift investments" are subject to various
penalties, including limitations on their activities and restrictions on their
FHLB advances. Failure to satisfy the QTL test would also bring into operation
restrictions on the activities that may be engaged in by HEI, HEIDI and their
other subsidiaries and could effectively result in the required divestiture of
ASB. At all times during 1998, ASB was in compliance with the QTL test. See
"Holding company regulation."

Federal Home Loan Bank System.  ASB is a member of the FHLB System which
- --------------------------------                                        
consists of 12 regional FHLBs. The FHLB System provides a central credit
facility for member institutions. ASB, as a member of the FHLB of Seattle, is
required to own shares of capital stock in the FHLB of Seattle in an amount
equal to the greater of 1% of ASB's aggregate unpaid residential loan principal
at the beginning of each year, 0.3% of total assets or 5% of FHLB advances
outstanding. The FHLBs serve as the central liquidity facilities for savings
associations and resources of long-term funds for financing housing. Long-term
advances may only be made for the purpose of providing funds for financing
residential housing. Additionally, at such time as an advance is made or
renewed, it must be secured by collateral from one of the following categories:
(1) fully disbursed, whole first mortgages on improved residential property, or
securities representing a whole interest in such mortgages; (2) securities
issued, insured or guaranteed by the U.S. Government or any agency thereof; (3)
FHLB deposits; and (4) other real estate-related collateral that has a readily
ascertainable value and with respect to which a security interest can be
perfected. The aggregate amount of outstanding advances secured by such other
real estate-related collateral may not exceed 30% of the member's capital.

Community Reinvestment.  In 1977, Congress enacted the Community Reinvestment
Act (CRA) to ensure that banks and thrifts help meet the credit needs of their
communities, including low- and moderate-income areas, consistent with safe and
sound lending practices. The OTS will consider ASB's CRA record in evaluating an
application for a new deposit facility, including the establishment of a branch,
the relocation of a branch or office, or the acquisition of an interest in
another bank or thrift. ASB received a CRA rating of "outstanding" from the OTS
in December 1997.

                                       40
<PAGE>
 
Other laws.  ASB is subject to federal and state consumer protection laws which
affect lending activities, such as the Truth-in-Lending Law, the Truth in
Savings Act, the Equal Credit Opportunity Act, the Real Estate Settlement
Procedures Act and several federal and state financial privacy acts. These laws
may provide for substantial penalties in the event of noncompliance. Management
of ASB believes that its lending activities are in compliance with these laws
and regulations.

For a discussion of federal and state interstate branching legislation, see
"Liquidity and capital resources--Savings bank" in HEI's MD&A.

In August 1996, federal legislation was enacted that repeals the percentage of
taxable income method of tax accounting for bad debt reserves used by ASB and
other "large" thrift institutions. In place of this bad debt reserve method, ASB
is required to use the specific charge-off method used by most other businesses.
These rules are generally effective for taxable years beginning after 1995. The
related transaction rules eliminate the potential recapture of federal income
tax deductions arising from the bad debt reserve created prior to 1988. Only
post-1987 reserve net additions are subject to recapture into taxable income
ratably over a six-year period, beginning in 1997. As of December 31, 1996, ASB
had a deferred tax liability of approximately $4.8 million for its post-1987
reserve.

Pending legislation. For a discussion of potential federal legislation
addressing the merger of the Bank Insurance Fund and SAIF, thrift rechartering
and financial modernization, and possible adverse effects on HEI, see "Liquidity
and capital resources--Savings bank" in HEI's MD&A.

Freight transportation regulation

The PUC has broad authority in its regulation of the intrastate business and
operations of YB. See "Other--Freight transportation--Hawaiian Tug & Barge Corp.
and Young Brothers, Limited." In particular, the PUC has the authority to review
and modify YB's intrastate rates and charges under the Hawaii Water Carrier Act.
In all rate proceedings under such act, YB has the burden of proving the
reasonableness of expenditures, contracts, leases or other transactions. An
adverse decision or policy adopted by the PUC, or a delay in granting requested
rate or other relief, could have a material adverse effect on the financial
condition, results of operations or liquidity of YB.

Environmental regulation

HEI and its subsidiaries are subject to federal and state statutes and
governmental regulations pertaining to water quality, air quality and other
environmental factors.

Water quality controls. As part of the process of generating electricity, water
used for condenser cooling of the electric utility subsidiaries' steam electric
generating stations is discharged into ocean waters or into underground
injection wells. The subsidiaries are required periodically to obtain permits
from the DOH in order to be allowed to discharge the water, including obtaining
permit renewals for existing facilities and new permits for new facilities. The
electric utility subsidiaries must obtain National Pollutant Discharge
Elimination System permits from the DOH to allow wastewater and storm water
discharges into state waters for their coastal generating stations and
Underground Injection Control (UIC) permits for wastewater discharge to
underground injection wells for one MECO facility and several HELCO facilities.

The Federal Oil Pollution Act of 1990 (OPA) governs actual or threatened oil
releases in navigable U.S. waters (inland waters and up to three miles offshore)
and waters of the U.S.' exclusive economic zone (up to 200 miles to sea from the
shoreline). Responsible parties under OPA are jointly, severally and strictly
liable for oil removal costs incurred by the federal government or the state and
damages to natural resources and real or personal property. Responsible parties
include vessel owners and operators. OPA imposes fines and jail terms ranging in
severity depending on how the release was caused. OPA also requires that
responsible parties submit certificates of financial responsibility sufficient
to meet the responsible party's maximum limited liability. HTB complies with
this requirement through coverage with the Water Quality Insurance Syndicate and
YB qualifies as a self-insurer. The Coast Guard issued interim guidelines in
September 1992, which included the requirement that a spill response plan be
submitted by February 18, 1993, and be finalized by August 18, 1993. The EPA and
federal Department of Transportation also have similar requirements for
submission of spill response plans. The EPA issued 

                                       41
<PAGE>
 
its proposed rules and guidelines on this matter in February 1993 and finalized
its rules in July 1994. With HTB exiting the fuel transportation business at the
end of 1993, the Company's freight transportation operations subject the Company
to significantly lessened environmental risks. Although HTB's fuel and
lubricating oil and the other cargo carried in its barges may be accidentally
discharged into ocean waters causing a pollution hazard, the quantities carried
do not pose a major environmental hazard. HTB and YB employees are trained to
respond to oil or other spills that occur. HTB and YB filed spill response plans
in 1993, 1995 and 1996. The utilities filed preliminary spill response plans in
1993 for certain facilities. Revised Facility Spill Response Plans (FSRPs) and
additional FSRPs were filed in 1994 and 1995.

Due to a leak in the fuel transfer system, approximately 100 gallons of bunker
fuel oil were released to a HELCO Shipman facility drainage well system in
November 1996. The release was reported to state and county agencies in December
1996. Although the fuel oil was removed from the well system and the well system
was cleaned, oil continued to seep back into the well system from behind the
retaining walls until March 1997. Monitoring and removal of this residual oil
continued. In March 1997, HELCO received a letter from the DOH concurring with
the ongoing cleanup approach and stating that more aggressive cleanup measures
should be considered if oil seepage into the drainage wells worsens. Oil seepage
into the well system has not been observed since March 1997.

Due to leaks in two wastewater treatment system tanks, an estimated 2,000
gallons of boiler cleaning wastewater was released to a HELCO Hill facility
drainage well in January 1997. After confirming that the wastewater discharged
exhibited characteristics of a hazardous waste, notification was provided to
federal, state and county agencies. A post-release drainage well sample
collected indicated that well conditions were nonhazardous. The treatment tanks
were repaired, the drainage well cleaned and a semiannual well status check was
performed by a consultant with satisfactory results. The DOH issued a Notice of
Apparent Violation of the UIC permit in February 1997. The DOH has not taken any
follow-up action regarding this incident and management does not expect any
future follow-up action to be taken.

In April 1997, HECO, on behalf of HELCO, notified the DOH that it became aware
that industrial oily wastewater was discharging into HELCO's Waimea facility's
dry well system in noncompliance with the facility's UIC permit. The discharge
of oily wastewater was stopped and, in May 1997, a written incident report was
submitted to the DOH. The DOH issued a Notice of Apparent Violation. The well
was cleaned and in July 1997 a response was submitted to a DOH request for
information. The DOH performed a site inspection in September 1997 and, in
January 1998, the DOH issued an NOV imposing a civil penalty fine on HELCO of
$36,000, which HELCO paid in January 1998. The DOH then closed this case. In
January 1999, however, oil was re-discovered in the dry well and the DOH was
notified. The reappearance of oil in the well is believed to be related to
seepage of residual subsurface oil into the well due to heavy rainfall. The well
was cleaned out and is being monitored. A status report was submitted to the DOH
in February 1999.

Air quality controls. The generation stations of the utility subsidiaries
operate under air pollution control permits issued by the DOH and, in a limited
number of cases, by the EPA. The entire electric utility industry is affected by
the 1990 Amendments to the Clean Air Act. Hawaii utilities may be affected by
the air toxics provisions (Title III) when the Maximum Allowable Control
Technology (MACT) emission standards are proposed for generation units. Hawaii
utilities are affected by the operating permit provisions (Title V). On November
26, 1993, the DOH adopted implementing regulations which required submission of
permit applications during 1994 for existing sources. All applications were
filed in 1994 as required and supplementary information was filed in 1995,1996
and 1997. Results of further air quality analyses could trigger requirements to
mitigate emission impacts. Title V permits have been issued for Honolulu,
Maalaea, Lanai City, Miki Basin and Palaau Power Plants. Permits for other
plants are pending.

On November 1, 1989, the DOH issued an NOV to MECO indicating that Maalaea units
X-1 and X-2 had exceeded operating limitations of 12 hours per day at various
times in 1988. These incidents resulted from unscheduled unit outages and
resulted in no net increase in emissions by MECO. 

                                       42
<PAGE>
 
Subsequently, MECO took steps to preclude future violations. An application for
a permit modification was submitted to the EPA, revising the operating hour
limitation to annual rather than daily. Approval was received from the EPA in
July 1992. Units X-1 and X-2 continue to operate in compliance with the revised
permit.

Following a unit overhaul, emission compliance tests conducted for MECO's
Maalaea Unit 14 in late 1995 indicated that particulate emissions were in excess
of PSD permit limits. Corrective actions were taken and a retest in February
1996 confirmed that the unit returned to compliance with PSD permit limits. All
test reports were submitted to the DOH. By letter dated July 15, 1996, the DOH
indicated that an NOV will be issued for the past violations.

By letter dated January 31, 1997, the DOH invited MECO to meet to discuss
settlement of open matters. An agreement was reached with the DOH to resolve the
NOV issued for X-1 and X-2 operating hours during 1988 and any other air permit
violations which may have occurred from November 1, 1989 until November 1, 1996
(including past violations of Maalaea Unit 14 discussed in the previous
paragraph). MECO and the DOH executed a final consent order, dated August 10,
1998, disposing of the NOV. In accordance with the order, MECO will pay $100,000
over two years to the Hawaii Nature Center for funding environmental education
projects.

Initial source tests in December 1989 and subsequent retesting for HELCO's CT-2
generating unit indicated particulate emissions above permitted levels.
Following analysis, HECO (on behalf of HELCO) proposed in November 1990 that the
permitted particulate limit be increased. By letter dated April 13, 1992, the
EPA concurred that revision is warranted. The DOH issued an NOV on August 17,
1992 for the noncomplying emissions. HECO and HELCO worked with the DOH, the
manufacturer and a consultant to determine an appropriate new emission limit for
particulates as well as oxides of nitrogen. In accordance with discussions with
the DOH, CT-2 continues to operate pending issuance of a revised permit. On
January 20, 1998, the DOH issued an NOV to HELCO for noncomplying emissions from
March 16, 1993 through December 20, 1994 and from March 22, 1996 through
November 6, 1997. HELCO paid fines totaling $22,100 in the settlement of both
the 1992 and 1998 NOVs. Unit CT-2 is currently operating within all permit
limits by virtue of its having passed its November 1997 and November 1998 source
tests. The DOH has prepared a draft permit for CT-2 with revised limits for
emissions of particulates and nitrogen oxides and will be scheduling a public
hearing.

For other air permit issues relating to HELCO, see the previous discussion under
"HELCO power situation--PSD permit."

On July 16, 1997, the EPA adopted national ambient air quality standards for
certain particulate matter and the ozone. The new standards will not require
local pollution controls until 2004 for the ozone and 2005 for particulate
matter, with no compliance determinations until 2007 and 2008, respectively, and
with possible extensions. The eventual impact of these new standards on the
Company is not known at this time.

Hazardous waste and toxic substances controls. The operations of the electric
utility and freight transportation subsidiaries are subject to regulations
promulgated by the EPA to implement the provisions of the Resource Conservation
and Recovery Act (RCRA), the Superfund Amendments and Reauthorization Act and
the Toxic Substances Control Act. The DOH has been working towards obtaining
primacy to operate state-authorized RCRA (hazardous waste) programs. The DOH
finalized RCRA administrative rules in mid-June 1994, with the rules becoming
effective on June 18, 1994. The DOH's state contingency plan and the State of
Hawaii Environmental Response Law (ERL) rules were adopted in August 1995.

Whether on a federal or state level, RCRA provisions identify certain wastes as
hazardous and set forth measures that must be taken in the transportation,
storage, treatment and disposal of these wastes. Some of the wastes generated at
steam electric generating stations possess characteristics which make them
subject to these EPA regulations. Since October 1986, all HECO generating
stations have operated RCRA-exempt wastewater treatment units to treat
potentially regulated wastes from occasional boiler waterside and fireside
cleaning operations. Steam generating stations at MECO and HELCO also operate
similar RCRA-exempt wastewater management systems. In March 1990, the EPA
changed 

                                       43
<PAGE>
 
RCRA testing requirements used to characterize a waste as hazardous which
potentially affected the hazardous waste generating status of all facilities.
HECO's continuing program to recharacterize all HECO, MECO and HELCO
wastestreams has demonstrated the adequacy of the existing treatment systems and
identified other potential compliance requirements. Waste recharacterization
studies indicate that treatment facility wastestreams are nonhazardous and no
change in RCRA generator status is required.

RCRA underground storage tank (UST) regulations require all facilities with USTs
used to store petroleum products to comply with costly leak detection, spill
prevention and new tank standard retrofit requirements within a specified
compliance period based on tank age. On August 5, 1996, the EPA conducted an UST
Field Citation inspection at the Ward Avenue complex. During the inspection HECO
was cited for a minor infraction, which was immediately corrected. HECO received
an NOV and paid a nominal fine.

During 1998, the DOH conducted UST inspections at HELCO's Kona and Kanoelehua
operations centers (May 1998); MECO's Kahului T&D baseyard (June 1998); and
HECO's Waiau power plant (August 1998), Koolau Baseyard (August 1998) and Kahe
power plant (September 1998). Both HELCO facilities were found to be operating
in compliance with UST regulations. The DOH subsequently issued NOVs for alleged
deficiencies in compliance with UST requirements for MECO's and HECO's
facilities. MECO received an NOV in July 1998 for the Kahului baseyard. MECO
completed corrective measures and is currently preparing its certification of
compliance status with the assistance of HECO's Environmental Department. The
DOH issued NOVs to HECO for the Koolau and Kahe facilities in December 1998, and
for the Waiau facility in January 1999. Corrective measures were completed and
certifications of compliance status were submitted to the DOH for Koolau and
Kahe in January 1999, and Waiau in February 1999. Additional enforcement actions
by the DOH are not anticipated at this time. UST regulations required that all
UST systems comply with new tank standards by December 22, 1998 or be closed.
All HECO, HELCO and MECO USTs currently meet these standards and continue in
operation.

The Emergency Planning and Community Right-to-Know Act under Superfund
Amendments and Reauthorization Act Title III requires HECO, MECO and HELCO to
report hazardous chemicals present in their facilities in order to provide the
public with information on these chemicals so that emergency procedures can be
established to protect the public in the event of hazardous chemical releases.
All HECO, MECO and HELCO facilities are in compliance with applicable annual
reporting requirements to the State Emergency Planning Commission, the Local
Emergency Planning Committee and local fire departments. In September 1995, the
EPA published a notice of proposed rule making to expand the types of industries
required to file annual Toxic Release Inventory reports (i.e., to report
facility releases of toxic chemicals). The final rule, issued on May 1, 1997,
includes the steam electric category (effective January 1, 1998), which
previously was exempt from Toxic Release Inventory reporting requirements.
Facilities are implementing actions to comply with reporting requirements.
Release reports for 1998 must be filed with the EPA by July 1, 1999.

The Toxic Substances Control Act regulations specify procedures for the handling
and disposal of polychlorinated biphenyls (PCB), a compound found in transformer
and capacitor dielectric fluids. HECO and its subsidiaries have instituted
procedures to monitor compliance with these regulations. In addition, HECO has
implemented a program to identify and replace PCB transformers and capacitors in
the HECO system. All HECO, MECO and HELCO facilities are currently believed to
be in compliance with PCB regulations. In 1997, the EPA published the final rule
on the PCB disposal amendments. The rule provides flexibility in selecting
disposal technologies for PCB wastes and expands the list of available
decontamination procedures; provides less burdensome mechanisms for obtaining
EPA approval for a variety of activities; clarifies and/or modifies certain
provisions where implementation questions have arisen; modifies the requirements
regarding the use and disposal of PCB equipment; and addresses outstanding
issues associated with the notification and manifesting of PCB wastes and
changes in the operation of commercial storage facilities. This rule streamlines
procedures and focuses on self-implementing requirements and the elimination of
duplication. Some activities currently requiring PCB disposal approvals will no
longer require those approvals. The EPA believes that this rule 

                                       44
<PAGE>
 
will result in substantial cost savings to the regulated community while
protecting against unreasonable risk of injury to health and the environment
from exposure to PCBs.

By letter dated August 21, 1992, the EPA issued to MECO a notice of potential
liability and request for information relating to a federal Superfund closure
investigation at the North American Environmental, Inc. (NAE) storage facility
in Clearfield, Utah. The EPA identified MECO as a potentially responsible party
for three PCB capacitors originally contracted for disposal by Westinghouse.
Although Westinghouse has already disposed of the capacitors, MECO was obligated
to comply with the information requests attached to the EPA notice. A
preliminary response to the EPA's information request was submitted to the EPA
on October 5, 1992. MECO has since received confirmation from Westinghouse that
the three capacitors were removed from the NAE facility and incinerated at Aptus
(an EPA-approved facility in Kansas) on September 16, 1992. By letter dated
December 2, 1992, the EPA notified MECO that a draft Administrative Order on
Consent (AOC) for the cleanup of the NAE facility had been sent to potentially
responsible parties that have waste remaining at the NAE site and to parties
that have expressed a desire to participate in the cleanup. MECO did not receive
a draft AOC because the three PCB capacitors were removed from the NAE facility
and incinerated. By letter dated February 8, 1993, Westinghouse confirmed that
it would indemnify MECO pursuant to its contract for this matter. In early 1995,
the EPA issued an AOC to the Freeport Center and the Defense Logistics Agency
(DLA). The NAE site received EPA closure in 1996. All PCB wastes were removed
and disposed of in accordance with the Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA). Final determination on cost recovery
from other PRPs remains with Freeport Center and the DLA. To date, MECO has not
received correspondence from either party.

The ERL, as amended, governs releases of hazardous substances, including oil, in
areas within the state's jurisdiction. Responsible parties under the ERL are
jointly, severally and strictly liable for a release of a hazardous substance
into the environment. Responsible parties include owners or operators of a
facility where a hazardous substance comes to be located and any person who at
the time of disposal of the hazardous substance owned or operated any facility
at which such hazardous substance was disposed. The DOH issued final rules (or
State Contingency Plan) implementing the ERL on August 17, 1995. Potential
exposure to liability under the ERL/State Contingency Plan is associated with
the release of regulated substances, including oil, to the environment.

For information regarding the investigation of the Honolulu Harbor area, see
Note 17 to HEI's Consolidated Financial Statements and Note 12 to HECO's
Consolidated Financial Statements. The Technical Work Group anticipates that the
Phase I report will be completed by the end of April 1999. Phase I work
includes:  1) data assimilation, review and evaluation to characterize the
extent of subsurface contamination; 2) data gap analysis to determine additional
areas requiring investigation; and 3) conceptual site model development,
including an assessment of probable exposure pathways.

Both HTB and YB generate small quantities of hazardous wastes as a result of
operations and equipment maintenance activities and have contracted with a firm
to dispose of these wastes in compliance with the EPA regulations and the RCRA
provisions. YB, as a public carrier, also moves hazardous wastes and explosives
for customers. Employees are trained in the applicable handling methods to
assist in the safe movement of these cargoes. Both HTB and YB are subject to the
jurisdiction of the Coast Guard which monitors ocean activities to ensure
compliance with federal regulations.

ASB may be subject to the provisions of CERCLA and regulations promulgated
thereunder. CERCLA imposes liability for environmental cleanup costs on certain
categories of responsible parties, including the current owner and operator of a
facility and prior owners or operators who owned or operated the facility at the
time the hazardous substances were released or disposed. CERCLA exempts persons
whose ownership in a facility is held primarily to protect a security interest,
provided that they do not participate in the management of the facility.
Although there may be some risk of liability for ASB for environmental cleanup
costs, the Company believes the risk is not as great for ASB, which specializes
in residential lending, as it may be for other depository institutions which
have a larger portfolio of commercial loans.

nr  Not rated.

The above ratings are not recommendations to buy, sell or hold any securities;
such ratings may be subject to revision or withdrawal at any time by the rating
agencies; and each rating should be evaluated independently of any other rating.
These ratings reflect only the view of the applicable rating agency at the time
the ratings are issued, from whom an explanation of the significance of such
ratings may be obtained. There is no assurance that any such credit rating will
remain in effect for any given period of time or that such rating will not be
lowered, suspended or withdrawn entirely by the applicable rating agency if, in
such rating agency's judgment, circumstances so warrant. Any such lowering,
suspension or withdrawal of any rating may have an adverse effect on the market
price or marketability of HEI's and/or HECO's securities, which could increase
the cost of capital of HEI and HECO. Neither HEI nor HECO management can predict
future rating agency actions or their effects on the future cost of capital of
HEI or HECO.

The revenue bonds in the above table are issued by the Department of Budget and
Finance of the State of Hawaii for the benefit of HECO and its subsidiaries, but
the source of their repayment are the unsecured obligations of HECO and its
subsidiaries under loan agreements and notes issued to the Department, including
HECO's guarantees of its subsidiaries' obligations. The payment of principal and
interest due on several series of these revenue bonds are insured by MBIA
Insurance Corporation, and the ratings of those bonds are based on the ratings
of the obligations of the bond insurer rather than HECO.

In December 1998, following the issuance of an additional $50 million of trust
preferred securities, Moody's downgraded HECO's preferred stock rating from baa1
to baa2 citing "the more material layer of [trust preferred] securities in
[HECO's] capital structure, which could have a priority claim in bankruptcy over
the holders of preferred stock, as opposed to a fundamental change in [HECO's]
credit quality."

In February 1999, S&P announced a new single credit rating scale for all fixed
income obligations, including debt, hybrid securities and preferred stock. HEI-
obligated preferred securities of trust subsidiary were rated BBB- on the old
scale and are now rated BB+ on the new single scale. HECO-obligated preferred
securities of trust subsidiaries were rated BBB on the old scale and are now
rated BBB- on the new scale.

In February 1999, S&P also lowered the amount of equity credit accorded to
preferred stock and trust preferred securities, but it also indicated that this
is unlikely to affect the credit ratings of issuers because this was only one
factor taken into account to establish their credit ratings.

Research and development
- ------------------------

HECO and its subsidiaries expensed approximately $2.2 million, $2.3 million and
$2.1 million in 1998, 1997 and 1996, respectively, for research and development.
Contributions to the Electric Power Research Institute accounted for most of the
expenses. There were also expenses in the areas of energy conservation,
environmental and emissions controls, and expenses for studies relative to
technologies that are applicable to HECO, its subsidiaries and their customers.

Employee relations
- ------------------

At December 31, 1998, the Company had 3,722 full-time employees, compared with
3,672 at December 31, 1997. At December 31, 1998 and 1997, HEI had 49 and 50
full-time employees, respectively.

HECO

At December 31, 1998, HECO and its subsidiaries had 2,020 full-time employees,
compared with 2,115 at December 31, 1997.

In August 1998, HECO, MECO and HELCO employees represented by the International
Brotherhood of Electrical Workers, AFL-CIO, Local 1260, ratified new collective
bargaining agreements covering approximately 67% of the employees of HECO, MECO
and HELCO.  The new collective bargaining agreements (including benefit
agreements) cover a two-year period from November 1, 1998 through October 31,
2000. The main provisions of the agreements include noncompounded wage increases
of 1.5% effective May 1, 1999 and 2.0% effective January 1, 2000, and lump sum
payments of $350 or $500 per employee following ratification. The parties also
signed an agreement committing to work towards resolving issues in order to
succeed in a competitive environment and towards seeking improvements in
efficiency and service while lowering costs, including changes in work practices
and rules.

HTB

HTB and YB have a collective bargaining agreement with the Inlandboatmen's Union
of the Pacific  effective from July 26, 1998 through June 30, 2001, which was
ratified on August 1, 1998. The agreement provides for a 1.9% wage increase for
the first year, a 1.8% wage increase for the second year and a 2.4% wage
increase for the third year. The agreement covers all unionized employees of HTB
and YB employed on ocean, interisland, harbor tug operations and dispatchers. It
excludes journeyman craftsmen (covered in YB's contract with the International
Longshoremen's and Warehousemen's Union), office clerical employees,
professional and management employees, guards and watchmen.

YB has a collective bargaining agreement covering the period of July 1, 1996
through June 30, 1999 with the International Longshoremen's and Warehousemen's
Union, Hawaii Division, Local 142. The agreement provides for a 13.4% wage
increase over the three-year period. The agreement covers all regularly
scheduled employees, receiving and delivery clerks on the docks loading and
discharging vessels, all maintenance personnel, documentation clerks and
customer service representatives employed by YB in the state. The agreement
excludes confidential employees, professional employees, supervisory employees,
guards and other clerical personnel. Renegotiation of this agreement typically
follows completion of the West Coast (Pacific Maritime Association) and
Longshore Hawaii contracts and begins six to eight months after the expiration
of the agreement. During this period, the agreement has typically been extended
on a daily basis with at least 72 hours prior written notice of cancellation.

The net book value of branches and office facilities is approximately $49
million. Of this amount, $39 million represents the net book value of the land
and improvements for the branches and office facilities owned by ASB and $10
million represents the net book value of ASB's leasehold improvements. The
leases expire on various dates from April 1999 through November  2014 and 20 of
the leases have extension provisions.

See Note 15 to HEI's Consolidated Financial Statements, incorporated herein by
reference to pages 60 to 61 of HEI's 1998 Annual Report to Stockholders,
portions of which are filed herein as HEI Exhibit 13.

In December 1994, five insurance agencies, which had served as insurance agents
for the HIG Group, filed a complaint against HEI, HEIDI and others. The
complaint set forth several causes of action, including breach of contract and
piercing the corporate veil. The plaintiffs asked for relief from the
defendants, including compensatory damages for lost commissions, business and
profits, and punitive damages. In 1995, the First Circuit Court of the State of
Hawaii granted defendants' motion for summary judgment dismissing all claims.
Judgment was entered and plaintiffs appealed. In March 1999, the Supreme Court
of the State of Hawaii affirmed the summary judgment dismissing all claims.

ITEM 5.   MARKET FOR REGISTRANTS' COMMON EQUITY AND RELATED 
          STOCKHOLDER MATTERS

HEI:

The information required by this item is incorporated herein by reference to
pages 25, 60 and 65 (Note 13, "Regulatory restrictions on net assets" and Note
18, "Quarterly information (unaudited)" to HEI's Consolidated Financial
Statements) of HEI's 1998 Annual Report to Stockholders, portions of which are
filed as HEI Exhibit 13. Certain restrictions on dividends and other
distributions of HEI are described in this report under "Item 1. Business--
Regulation and other matters--Restrictions on dividends and other
distributions." The total number of holders of record of HEI common stock as of
March 12, 1999, was 19,280.

                                       51
<PAGE>
 
HEI has issued unregistered common stock during the past three years pursuant to
the HEI Nonemployee Director Stock Plan (the Director Plan), the HECO Utility
Group Team Incentive Plan and the HECO Utility Group Team Incentive Plan for
Bargaining Unit Employees (collectively, the Team Incentive Plan).  Under the
Director Plan, 60% of the annual retainer payable to nonemployee directors is
paid in HEI common stock.  Under the Team Incentive Plan, eligible employees of
HECO, MECO and HELCO receive awards of HEI common stock based on the attainment
of performance goals by the respective companies.

In 1996, 1997 and 1998, the Director Plan issued 4,836, 6,379 and 4,736 shares
of HEI common stock, respectively, in exchange for the retention of cash by HEI
that would otherwise have been paid to directors as retainers in the aggregate
amounts of $167,000, $213,000 and $192,000, respectively, and the Team Incentive
Plan issued 29,780, 42,743 and 9,006 shares of HEI common stock, respectively,
in exchange for cash received by HEI from the electric utility subsidiaries in
the aggregate amounts of $1.2 million, $1.5 million and $0.4 million,
respectively.  The shares issued under the Director Plan were not registered
since they did not involve a "sale" as defined under Section 2(3) of the
Securities Act of 1933, as amended.  Participation by nonemployee directors of
HEI in the Director Plan is mandatory and thus does not involve an investment
decision.  The shares issued under the Team Incentive Plan were not registered
because their initial sales to HECO, MECO and HELCO were exempt as transactions
not involving any public offering under Section 4(2) of the Securities Act of
1933, as amended, and because their subsequent award to eligible employees did
not involve a "sale," as defined in Section 2(3) of the Securities Act of 1933,
as amended.  Awards of HEI common stock under the Team Incentive Plan are made
to eligible employees on the basis of their attainment of performance goals
established by their respective companies and no cash or other tangible or
definable consideration is paid for the shares.

HECO:

The information required with respect to "Market information" and "holders" is
not applicable. Since the corporate restructuring on July 1, 1983, all the
common stock of HECO has been held solely by its parent, HEI, and is not
publicly traded.

The dividends declared and paid on HECO's common stock for the four quarters of
1998 and 1997 were as follows:

(1)  The HECO Named Executive Officers are eligible for an incentive award under
     the Company's annual Executive Incentive Compensation Plan (EICP). EICP
     bonus payouts are reflected as compensation for the year earned.
(2)  Covers perquisites of $107,412 for Mr. May for 1996 which he recognized as
     imputed income under the Internal Revenue Code, including $95,691 under the
     category club membership (representing once in a lifetime reimbursement of
     initiation fees of $50,000 grossed up for taxes, plus reimbursement of
     monthly dues not grossed up for taxes). Amounts for Mr. Oyer and Mr. Hirata
     represent above-market earnings on deferred compensation.

(4)  Long-Term Incentive Plan (LTIP) payouts are determined in the second
     quarter of each year for the three-year cycle ending on December 31 of the
     previous calendar year. If there is a payout, the amount is reflected as
     LTIP compensation in the table for the previous year (for Mr. May and Mr.
     Jezierny). In May 1997, LTIP payouts were made for the 1994-1996
     performance cycle and are reflected as LTIP compensation in the table for
     1996. In May 1998, no LTIP payouts were made for the 1995-1997 performance
     cycle because none of the minimum threshold levels was achieved. The
     determination of whether there will be a payout under the 1996-1998 LTIP
     will not be made until the second quarter of 1999.
(5)  Represents amounts accrued each year by the Company for certain death
     benefits provided to the named executive officers. Additional information

     Stockholders to be held on April 27, 1999.

Option grants in last fiscal year
- ---------------------------------

A stock option was granted in 1998 to only one of the HECO Named Executive
Officers, Mr. May. Additional information required under this item is
incorporated by reference on pages 14 to 15 of HEI's Definitive Proxy Statement,
prepared for the Annual Meeting of Stockholders to be held on April 27, 1999.

Aggregated option exercises and fiscal year-end option values
- -------------------------------------------------------------

The following table shows the stock options, including dividend equivalents,
exercised by the HECO Named Executive Officers in 1998. Also shown is the number
of unexercised options and the value of unexercised in the money options,
including dividend equivalents, at the end of 1998. Under the Stock Option and
Incentive Plan, dividend equivalents have been granted to all HECO Named
Executive Officers as part of their 1997 stock option grants, to Mr. May as part
of his 1998 and 1996 stock option grants, to Mr. Oyer as part of his 1988 stock
option grant and to Mr. Jezierny as part of his stock option grants for each of
the years 1990 through 1996.

Dividend equivalents permit a participant who exercises a stock option to obtain
at no additional cost, in addition to the option shares, the amount of dividends
declared on the number of shares of common stock with respect to which the
option is exercised during the period between the grant and the exercise of the
option. Dividend equivalents are computed as of each dividend record date
throughout the four-year vesting period (vesting in equal installments) which
begins on the date of grant, both with respect to the number of shares
underlying the option and with respect to the number of dividend equivalent
shares previously credited to the executive officer and not issued during the
period prior to the dividend record date.

Executive Management Compensation
- ---------------------------------

Changes to executive compensation for the HECO Named Executive Officers are
approved by the HEI Compensation Committee which is composed of five independent
nonemployee directors. All changes approved by the Committee concerning the HECO
Named Exceutive Officers are reviewed and approved by the HEI Board of Directors
as well as the HECO Board of Directors.

HECO Board of Directors
- -----------------------

Committees of the HECO Board
- ----------------------------

During 1998, the Board of Directors of HECO had only one standing committee, the
Audit Committee, which was comprised of three nonemployee directors: Diane J.
Plotts, Chairman, Anne M. Takabuki and Paul C. Yuen. The Audit Committee holds
such meetings as it deems advisable to review the financial operations of HECO.
In 1998, the Audit Committee held six meetings to review with management, the
internal auditor and HECO's independent auditors the activities of the internal
auditor, the results of the annual audit by the independent auditors and the
financial statements which are included in HECO's 1997 Annual Report to
Stockholder.

Remuneration of HECO Directors and attendance at meetings
- ---------------------------------------------------------

In 1998, Paul C. Yuen and Anne M. Takabuki were the only nonemployee directors
of HECO who were not also directors of HEI. They were each paid a retainer of
$20,000, 60% of which was distributed in the common stock of HEI pursuant to the
HEI Nonemployee Director Stock Plan and 40% of which was distributed in cash.
The number of shares of stock distributed was based on a share price of $40.44,
which is equal to the average high and low sales prices of HEI common stock on
May 1, 1998, with a cash payment made in lieu of any fractional share. The
nonemployee directors of HECO who were also nonemployee directors of HEI did not
receive a separate retainer from HECO. In addition, a fee of $700 was paid in
cash to each nonemployee director (including nonemployee directors of HECO who
are also nonemployee directors of HEI) for each Board and Committee meeting
attended by the director. The Chairman of the HECO Audit Committee was paid an
additional $100 for each Committee meeting 

                                       58
<PAGE>
 
attended. Employee members of the Board of Directors are not compensated for
attendance at any meeting of the Board or Committees of the Board.

In 1998, there were five regular bi-monthly meetings, one joint meeting and one
special joint meeting of the HECO Board of Directors. All incumbent directors
attended at least 75% of the combined total number of meetings of the Board and
the Committee on which they served.

                        HAWAIIAN ELECTRIC COMPANY, INC.

                           NOTICE TO SOLE STOCKHOLDER


       As required by Section 415-48.5 of the Hawaii Revised Statutes ("Section
415-48.5"), notice is hereby given that the Board of Directors of HAWAIIAN
ELECTRIC COMPANY, INC., a Hawaii corporation (the "Corporation") has proposed an
amendment to the Amended Articles of Incorporation of the Corporation which
would eliminate the personal liability of the directors of the Corporation in
certain actions brought by the stockholders or the Corporation. Section 415-48.5
grants Hawaii corporations the power to adopt such amendments. The form of the
proposed amendment is enclosed herewith.

       If adopted, the proposed amendment will eliminate the personal liability
of directors for monetary damages in actions brought by stockholders or the
Corporation for breach of fiduciary duty as a director. Under Section 415-48.5,
however, the personal liability of a director will not be eliminated or limited
for (i) any breach of the director's duty of loyalty to the Corporation or its
stockholders, (ii) any act or omission of the director not performed in good
faith, or which involves intentional misconduct or knowing violation of law, or
which constitutes a willful or reckless disregard of the director's fiduciary
duty, (iii) the director's willful or negligent violation of any provision of
the Hawaii Business Corporation Act (Chapter 415, Hawaii Revised Statutes)
regarding payment of dividends or stock purchase or redemption, or (iv) any
transaction from which the director received an improper benefit.

       Under Section 415-48.5, the proposed amendment must be adopted by the
affirmative vote of the holders of two-thirds of the shares represented at a
stockholders' meeting and having voting power; provided that the vote also
constitutes a majority of the shares having voting power.

       The Board of Directors believes that the adoption of the proposed
amendment will be an important step in inducing qualified persons to serve on
the Corporation's Board of Directors. In the absence of such a provision, it is
believed that many qualified persons will decline to serve because of the
liability exposure to which directors of publicly-held corporations are
subjected.

       If the proposed form of amendment is acceptable, please execute and
return to the Secretary of the Corporation the enclosed form of written consent
adopting the proposed amendment. If you have any questions on these matters,
please contact the President of the Corporation.

                                       Very truly yours,
                                       BOARD OF DIRECTORS

                        RESOLUTION OF BOARD OF DIRECTORS

                        HAWAIIAN ELECTRIC COMPANY, INC.

            Re:   Approving an Amendment to the Amended
                  Articles of Incorporation - Limiting
                  the Liability of Directors

                           Adopted - March 16, 1990
                           -------   --------------


            RESOLVED, that the Board of Directors of HAWAIIAN ELECTRIC COMPANY,

INC. hereby recommends to the sole stockholder of the corporation that, at the

1990 Annual Meeting, the sole stockholder of the corporation authorizes and

approves an amendment to the Amended Articles of Incorporation of the Company by

adding thereto a new Article, to be designated "XIII," and to read in its

entirety as follows:

                                 "ARTICLE XIII

            The personal liability of directors of the corporation for monetary
     damages shall be eliminated to the fullest extent permissible under Hawaii
     law, including, without limitation, to the fullest extent permissible under
     Section 415-48.5 of the Hawaii Revised Statutes, as may be amended from
     time to time.  No repeal or amendment of this Article directly or by
     adoption of an inconsistent provision of these Amended Articles of
     Incorporation will be effective with respect to the liability of a director
     for acts or omissions occurring prior to such repeal or amendment."

     Company, and Maui Electric Company, Limited, dated November 30, 1989, as
     Amended on November 1, 1990

This will confirm and document the Agreement between A&B Hawaii, Inc., through
its division, Hawaiian Commercial & Sugar Company ("HC&S") and Maui Electric
Company, Limited ("MECO") to extend the term of the Amended and Restated Power
Purchase Agreement Between HC&S and MECO (the "Power Purchase Agreement") as

1.  The Power Purchase Agreement shall remain in full force and effect through
    December 31, 2001, and from year to year thereafter; subject to termination
    on or after January 1, 2002, on not less than two (2) years' prior written
    notice by either party.

2.  All other terms and conditions of the Power Purchase Agreement shall remain
    unmodified for the extended term set forth above.

3.  To the extent that this Agreement to extend the Power Purchase Agreement
    requires the approval of the Public Utilities Commission ("PUC") of the
    State of Hawaii, it is expressly understood and agreed that the obligations
    of MECO and HC&S hereunder are contingent upon the continuing approval of
    the PUC.

If the foregoing meets with your approval, please execute the below
acknowledgment and return the original to me, retaining the duplicate original

the future.

              HAWAIIAN ELECTRIC INDUSTRIES RETIREMENT SAVINGS PLAN
              ----------------------------------------------------

     In accordance with Section 10.1 of the Hawaiian Electric Industries

Pension Investment Committee hereby amends the Plan as follows:

     1.  Section 1.7 is deleted in its entirety and is replaced by a new Section
1.7 to read as follows:

          "1.7  Compensation means all straight-time pay and commissions paid or
                ------------                                                    
          accrued during the Plan Year for services rendered to a Participating
          Employer.  Compensation shall include elective contributions made by a
          Participating Employer to this Plan or to a cafeteria plan that are
          excluded from the taxable income of the Employee under Sections
          402(e)(3) or 125 of the Code.  Compensation shall not include overtime

          Participating Employer to this Plan or any other employee benefit

          Special executive compensation is noncash compensation and
          nonqualified deferred compensation available only to a select group of
          management Employees. Compensation earned prior to an Eligible
          Employee becoming a Participant shall not be counted in determining
          contributions to the Plan. Compensation shall be limited to $160,000
          annually, as adjusted for increases in the cost of living in
          accordance with Sections 401(a)(17)(B) and 415(d) of the Code.

          year, without modification. ADP Compensation shall be limited to
          $160,000 annually, as adjusted for increases in the cost of living in
          accordance with Sections 401(a)(17)(B) and 415(d) of the Code.

          '415 Compensation' means the Employee's Box 1, W-2 earnings for the

          402(e)(3) or 125 of the Code."

     2.  Section 4.1(b)(6) is deleted in its entirety and is replaced by a new
Section 4.1(b)(6) to read as follows:

          "(6) For purposes of this Section 4.1, 'compensation' shall mean ADP
          Compensation."

     3.   Section 4.5(d)(2) is deleted in its entirety and is replaced by a new
