NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   NATURE OF OPERATIONS.  Southwest Gas Corporation (the Company) is
comprised of two segments:  Natural gas operations (Southwest or the natural
gas operations segment) and construction services.  Southwest purchases,
transports, and distributes natural gas to customers in portions of Arizona,
Nevada, and California.  Natural gas sales are seasonal, peaking during the
winter months.  Variability in weather from normal temperatures can materially
impact results of operations.  Northern Pipeline Construction Co. (Northern or
the construction services segment), a wholly owned subsidiary, is a full-
service underground piping contractor which provides utility companies with
trenching and installation, replacement, and maintenance services for energy
distribution systems.

   DISCONTINUED OPERATIONS.  In July 1996, the Company completed the sale of
the assets and liabilities of PriMerit Bank (the Bank) to Norwest Corporation. 
The results of operations of the Bank are shown as discontinued operations in
the accompanying financial statements.

   BASIS OF PRESENTATION.  The consolidated financial statements included
herein have been prepared by the Company, without audit, pursuant to the rules
and regulations of the Securities and Exchange Commission.  Certain
information and footnote disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to such rules and regulations.  The preparation
of the consolidated financial statements requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the
reporting period.  Actual results could differ from those estimates.  In the
opinion of management, all adjustments, consisting of normal recurring items
and estimates necessary for a fair presentation of the results for the interim
periods, have been made.  It is suggested that these consolidated financial
statements be read in conjunction with the financial statements and the notes
thereto included in the Company's 1996 Annual Report to Shareholders, which is
incorporated by reference into the Form 10-K, and 1997 quarterly reports on
Form 10-Q.

   INTERCOMPANY TRANSACTIONS.  During the nine months ended September 30,
1997, the construction services segment recognized $26 million of revenues
generated from contracts with Southwest.  At September 30, 1997, accounts
receivable for these services was $3.1 million.  The accounts receivable
balance, revenues, and associated profits are included in the consolidated
financial statements of the Company and were not eliminated during
consolidation.  Statement of Financial Accounting Standards (SFAS) No. 71,
"Accounting for the Effects of Certain Types of Regulation," provides that
intercompany profits on sales to regulated affiliates should not be eliminated
in consolidation if the sales price is reasonable and if future revenues

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS

The Company is principally engaged in the business of purchasing,
transporting, and distributing natural gas.  Southwest is the largest
distributor in Arizona, selling and transporting natural gas in most of
southern, central, and northwestern Arizona, including the Phoenix and Tucson
metropolitan areas.  Southwest is also the largest distributor and transporter
of natural gas in Nevada, and serves the Las Vegas metropolitan area and
northern Nevada.  In addition, Southwest distributes and transports natural
gas in portions of California, including the Lake Tahoe area in northern
California and high desert and mountain areas in San Bernardino County.

Southwest purchases, transports, and distributes natural gas to approximately
1,124,000 residential, commercial, industrial and other customers, of which
58 percent are located in Arizona, 32 percent are in Nevada, and 10 percent
are in California.  During the twelve months ended September 30, 1997,
Southwest earned 55 percent of operating margin in Arizona, 35 percent in
Nevada, and 10 percent in California.  During this same period, Southwest
earned 62 percent of operating margin from residential customers, 23 percent
from commercial customers, and 15 percent from industrial and other customers. 
These patterns are consistent with prior years and are expected to continue.

Northern is a full-service underground piping contractor which provides
utility companies with trenching and installation, replacement, and
maintenance services for energy distribution systems.

CAPITAL RESOURCES AND LIQUIDITY

The capital requirements and resources of the Company generally are determined
independently for the natural gas operations and construction services
segments.  Each business activity is generally responsible for securing its
own financing sources.  The capital requirements and resources of the
construction services segment are not material to the overall capital
requirements and resources of the Company.

Southwest continues to experience significant population growth throughout its
service territories.  This growth has required large amounts of capital to
finance the investment in infrastructure, in the form of new transmission and
distribution plant, to satisfy consumer demand.  Southwest estimates
construction expenditures during the three-year period ending
December 31, 1999 will be approximately $468 million.  During the three-year
period, cash flow from operating activities (net of dividends) is estimated to
fund approximately one-half of the gas operations total construction
expenditures.  A portion of the construction expenditure funding will be
provided by $30 million of funds held in trust, at December 31, 1996, from the
issuance of industrial development revenue bonds (IDRB).  The remaining cash
requirements are expected to be provided by external financing sources.  The
timing, types, and amounts of these additional external financings will be
dependent on a number of factors, including conditions in the capital markets,
timing and amounts of rate relief, and growth levels in Southwest service
areas.  These external financings may include the issuance of both debt and
equity securities, bank and other short-term borrowings, and other forms of
financing.  Due to the significant size of the current construction program,
differences between estimated and actual results are expected to occur. 
Actual events, and the timing of those events, frequently do not occur as
expected, and can impact, favorably or unfavorably, anticipated cash flows.

For the twelve months ended September 30, 1997, natural gas construction
expenditures totaled $184 million.  Approximately 78 percent of these
expenditures represents new construction and the balance represents costs
associated with routine replacement of existing transmission, distribution and
general plant.  Financing for recent construction expenditures and for other
corporate purposes was provided primarily by the issuances of medium-term
notes in January, February, June and September 1997 totaling $100 million and
a $16 million issuance of commercial paper in February 1997.

Cash flows from operating activities during the nine and twelve months ended
September 30, 1997 were negatively affected by increases in the cost of gas
during the fourth quarter of 1996 and first quarter of 1997.  Higher gas costs
coupled with refunds to customers of previously overcollected amounts shifted
the deferred purchased gas cost balance from a $39.6 million payable, at
September 30, 1996, to a $64.8 million receivable, at September 30, 1997, a
$104 million change.  Southwest must first obtain regulatory approval before
changing the rates it charges for recovery of gas costs. 

The increase in the cost of gas resulted from several factors including
reduced natural gas storage supplies nationwide following colder-than-normal
temperatures in the East and Midwest during the winter heating season of
1995/1996.  Domestic storage supplies were not fully replenished during the
summer months of 1996 because natural gas prices did not fall as much as
expected, and companies were shifting to "just-in-time" delivery practices in
lieu of storage.  Reduced availability coupled with increased weather-related
demand for supplies during the winter heating season of 1996/1997 were the
primary reasons for the increased cost of natural gas.  These increases not
only impacted Southwest, but local gas distribution companies throughout the
country.

Southwest intends to file for recovery of the accumulated balances in all
applicable rate jurisdictions.  In  January 1997, Southwest submitted a
purchased gas cost adjustment (PGA) filing with the Public Utilities
Commission of Nevada (PUCN). In April 1997, the filing was amended.  In
September 1997, annual increases of $10.1 million, or 9 percent, in the
southern Nevada rate jurisdiction and $6 million, or 14 percent, in the
northern Nevada rate jurisdiction were granted effective September 1997.  In
approving the increase, the PUCN indicated the PGA mechanism may need to be
replaced with one that includes a price incentive mechanism.  The Company had
recommended during the hearing  process that the PUCN adopt such a mechanism.

In June 1997, Southwest submitted an additional PGA filing with the PUCN. 
This annual PGA filing addressed the increased costs of natural gas since the
beginning of 1997 as well as the recovery of costs previously deferred.  In
September 1997, the filing was amended to reflect changes necessary as a
result of the September 1997 order on the previous PGA filing.  If approved as
amended, the filing would result in annual increases, above the revenue levels
approved in the previous PGA order, of $23.1 million, or 18 percent, in the
southern Nevada rate jurisdiction and $8.4 million, or 17 percent, in the
northern Nevada rate jurisdiction.  Hearings on this filing commenced in 
October 1997 and are ongoing.  A final decision is expected from the PUCN 
prior to year-end. 

In September 1997, Southwest submitted a PGA filing with the California Public
Utilities Commission (CPUC) to increase rates annually by $10 million, or 19
percent, in the southern California rate jurisdiction.  The rates are expected
to become effective by December 1997.

year.  Natural gas operations results declined $0.01 per share.  See separate
discussion at RESULTS OF NATURAL GAS OPERATIONS for changes as they relate to
gas operations.  Construction services results declined $0.02 per share from
the previous period primarily resulting from lower-than-anticipated revenues. 
Revenues declined 15 percent due to project cancellations and curtailments in
portions of California, Washington, Missouri, and Kansas.  Northern has
reorganized and closed offices in some of these areas and is pursuing new
contracts in other areas to improve profitability.  Average shares
outstanding increased 672,000 shares between years primarily resulting from
continuing issuances under the Company Dividend Reinvestment and Stock

per share were $0.01 during the current period.  In the prior period,
construction services contributed $0.08 per share, however, those results
excluded the months of January through April 1996 which are typically loss
months.  In addition, the decline was a result of various project
cancellations and curtailments.  To improve profitability, Northern is
pursuing new contracts and has reorganized and closed some offices.  Average
shares outstanding increased 1.4 million shares between years primarily due to
a 1.4 million share issuance in April 1996 to acquire Northern and issuances
under the Company Dividend Reinvestment and Stock Purchase Plan.

For the purposes of computing the ratios of earnings to fixed charges,
earnings are defined as the sum of pretax income from continuing operations
plus fixed charges.  Fixed charges consist of all interest expense including
capitalized interest, one-third of rent expense (which approximates the
interest component of such expense), preferred securities distributions and
amortized debt costs.

Contribution from natural gas operations declined $515,000 compared to the
third quarter of 1996.  The decline was principally the result of higher
operating and financing expenses incurred as a result of the expansion and
upgrading of the gas system to accommodate continued customer growth,
partially offset by an improvement in margin.

Operating margin increased $5 million, or eight percent, in the third quarter
of 1997 when compared to the third quarter of 1996.  The operating margin
improvement was primarily the result of customer growth and general rate
relief granted in Arizona jurisdictions effective September 1997.  Southwest
added approximately 60,000 customers during the past twelve months, a six
percent increase. 

Operations and maintenance expenses increased $1.2 million, or two percent,
reflecting general increases in labor, purchased goods and services.  

Depreciation expense and general taxes increased $1.9 million, or eight
percent, as a result of construction activities.  Average gas plant in service
increased $178 million, or 11 percent, as compared to the third quarter of
1996.  The increase reflects ongoing capital expenditures for the upgrade of
existing operating facilities and the expansion of the system to accommodate
continued customer growth.

Financing costs increased $2.4 million, or 16 percent, over the prior period. 
This increase is primarily attributed to higher short-term borrowings
outstanding during the current quarter and an increase in long-term debt
reflecting $100 million of medium-term note issuances during 1997.  The
increase in short-term debt reflects the need for short-term financing to
cover higher gas costs experienced during the fourth quarter of 1996 and first
quarter of 1997.

Contribution to consolidated net loss improved $6.8 million compared to the
nine months ended September 1996.  The improvement was the result of an
increase in operating margin, offset somewhat by higher operating and
financing expenses.

Operating margin increased $27.1 million, or 11 percent, during the nine
months ended September 1997 compared to the same period in 1996 due primarily
to continued customer growth throughout the Southwest service areas, general
rate relief granted in Nevada jurisdictions effective July 1996, and more
favorable weather conditions during the first quarter of 1997 relative to the
first quarter of 1996.

Operations and maintenance expenses increased $3.6 million, or two percent,
reflecting increases in labor and maintenance costs along with incremental
operating expenses associated with providing service to the growing Southwest
customer base.

Depreciation expense and general taxes increased $5.4 million, or eight
percent, resulting from an increase in average gas plant in service of $167
million, or ten percent.  This increase reflects capital expenditures for the
upgrade of existing operating facilities and the expansion of the system to
accommodate new customers being added to the system.

Financing costs increased $5.9 million, or 14 percent, during the nine months
ended September 1997, over the comparative prior period.  Average total debt
outstanding during the period increased due to the financing of construction
expenditures and working capital needs and included higher short-term debt,
the issuance of medium-term notes during 1997, and the drawdown of IDRB funds
held in trust.

                                                  ==========    ==========

Contribution to consolidated net income increased $13 million compared
to the corresponding twelve-month period ended September 1996.  The
increase was the result of an improvement in operating margin, offset
somewhat by higher operating and financing expenses.

Operating margin increased $44.9 million due to customer growth, rate
relief, and improved, but warmer-than-normal, weather conditions. 
Southwest billed an average of 61,000 more customers per month than
during the previous twelve-month period which contributed approximately
$10 million of additional margin.  General rate relief, primarily
related to Nevada jurisdictions, contributed $15 million incrementally
to operating margin.  Weather-related variances between periods
resulted in a $20 million increase in operating margin from weather-
sensitive customers.  On a weather-normalized basis, operating margin
would have been approximately $12 million greater than actually
reported for the twelve months ended September 30, 1997 and $32 million
higher in the previous period. 

Operations and maintenance expenses increased $9.7 million, or five
percent, reflecting increases in labor and maintenance costs along with
incremental operating expenses associated with providing service to the
steadily growing Southwest customer base.

Depreciation expense and general taxes increased $6.6 million, or seven
percent, as a result of construction activities.  Average gas plant in
service for the current twelve-month period increased $162 million, or
ten percent, compared to the corresponding period a year ago.  This was
attributed to the upgrade of existing operating facilities and the
expansion of the system to accommodate customer growth.  

Financing costs increased $6.3 million, or 11 percent, during the
twelve months ended September 30, 1997 over the comparative prior
period.  Average total debt outstanding during the period increased due
to the financing of construction expenditures and working capital needs
and included higher short-term debt, the issuance of medium-term notes
during 1997, and the drawdown of IDRB funds held in trust. 
Additionally, the current year reflects the full annual cost of the 
$60 million preferred securities issued in October 1995.

RATES AND REGULATORY PROCEEDINGS

  ARIZONA

In November 1996, Southwest filed a general rate application with the
Arizona Corporation Commission (ACC) seeking approval to increase
revenues by $49.3 million annually for both of its Arizona rate
jurisdictions.  Southwest was seeking rate relief for increased
operating costs, changes in financing costs, and improvements and
additions to the distribution system.  In  August 1997, the ACC
approved a settlement of the general rate case providing the Company
with a $32 million general rate increase effective September 1, 1997. 
The settlement achieved a number of favorable rate design improvements
and tariff restructuring changes including consolidation of the
southern and central Arizona rate jurisdictions for ratemaking purposes 
and better matching of rates with the costs of serving various customer 
classes.  The timing of the increase is important to the Company because 
it provides the benefit of having new rates in place before the start of 
the 1997/1998 winter heating season.

  FERC

In July 1996, Paiute Pipeline Company, a wholly owned subsidiary of the
Company, filed a general rate case with the Federal Energy Regulatory
Commission (FERC) seeking approval to increase revenues by $6.9 million
annually.  Paiute is seeking rate relief for increased costs associated
with transmission system additions and improvements, higher
depreciation rates, operating cost increases including labor, and an
increase in the allowed rate of return.  Interim rates reflecting the
increased revenues became effective in January 1997, subject to refund
until a final order is issued.  In June 1997, a settlement agreement was
filed with the FERC which, if approved, would authorize a $3.2 million general 
rate increase effectve January 1997.  An order approving the settlement 
agreement was issued in October 1997 and is expected to become final in 
November 1997.  Paiute has accrued a liability to customers for the difference
between the rates collected since January 1997 and the estimated amount of rate 
relief to ultimately be granted.  Refunds for this difference will be made to 
customers within 60 days of the effective date.

  CALIFORNIA

NORTHERN CALIFORNIA EXPANSION PROJECT.  In 1995, Southwest initiated a
multi-year, three-phase construction project to expand its northern
California service territory and extend service into Truckee,
California.  (See Note 8 of the Notes to Consolidated Financial
Statements of the 1996 Annual Report to Shareholders, incorporated by
reference into the Form 10-K, for additional background information.) 
In July 1997, Southwest filed an application requesting authorization
from the California Public Utilities Commission (CPUC) to modify the
terms and conditions of the certificate of public convenience and
necessity granted by the CPUC in 1995.

In the new application, Southwest is requesting that the cost cap of
$29.1 million, originally approved by the CPUC, be increased to $46.8
million; that the scope of Phase III construction be revised to include
2,900 of the initially proposed 4,200 customers; and that Southwest be
permitted to collect contributions or advances from customer applicants
desiring service in the expansion area who were not identified to
receive service during the expansion phases as modified within the new
application.  Southwest has proposed to recover the incremental costs
above the original cost cap on a dollar-for-dollar basis through a
surcharge mechanism.  In August 1997, the Office of Ratepayer Advocates filed 
a protest to the Southwest application indicating that the terms of 
the original agreement should be adhered to. In September, a hearing was 
held to discuss the filing and related protest.  Southwest has until 
December 1997, to file additional comments related to the protest.  
Management expects the CPUC to issue a final decision during the first 
quarter of 1998.            

                                       13<PAGE>
                                         
<PAGE>
For 1997, construction work on this project has been limited to the
installation of services and meters off existing mains for
approximately 900 additional customers at a cost of approximately 
$1 million.  Phase III, if approved as modified in the July 1997
application, would be completed during the 1998 and 1999 construction
seasons with construction expenditures estimated at $11 million.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In February 1997, the Financial Accounting Standards Board issued two
new accounting pronouncements. Statement of Financial Accounting
Standards (SFAS) No. 128, "Earnings per Share," establishes standards
for computing and presenting earnings per share (EPS).  This statement
replaces the presentation of primary EPS with basic EPS and fully
diluted EPS with diluted EPS.  It also requires the presentation of
basic and diluted EPS on the face of the income statement for all
entities with complex capital structures and requires a reconciliation
of the numerator and denominator of the basic EPS computation to the
numerator and denominator of the diluted EPS computation. This
statement becomes effective December 31, 1997.  The Company has
reviewed the requirements of SFAS No. 128 and does not anticipate any
material changes in EPS amounts previously reported.

The second pronouncement issued was SFAS No. 129, "Disclosure of
Information about Capital Structure."  SFAS No. 129 reaffirms standards
for disclosing information about an entity's capital structure.  The
statement becomes effective December 31, 1997.  The disclosure
requirements of this standard are not anticipated to significantly
change current reporting practices of the Company.

In June 1997, the Financial Accounting Standards Board issued two new
accounting pronouncements.  SFAS No. 130, "Reporting Comprehensive
Income," establishes standards for reporting and displaying
comprehensive income and its components in a full set of general-
purpose financial statements.  The components are required to be
reported in a financial statement that is displayed with the same
prominence as other financial statements.  This statement becomes
effective January 1, 1998.  The Company has reviewed the requirements
of SFAS No. 130 and does not expect any material change to its current
financial statement presentation format.

The second pronouncement issued was SFAS No. 131, "Disclosures about
Segments of an Enterprise and Related Information."  SFAS No. 131
establishes standards for the way that public business enterprises
report information about operating segments in annual financial
statements and requires that those enterprises report selected
information about operating segments in interim financial reports
issued to shareholders.  The statement becomes effective for 1998
annual financial statements.  The disclosure requirements of this
statement are not expected to significantly change current reporting
practices of the Company.

(14), as the Board of Directors or the shareholders by amendment of these
Bylaws may establish, provided, however, that a reduction in the authorized
number of directors shall not remove any director prior to the expiration of
his term of office, and provided further that the shareholders may, pursuant
to law, establish a different and definite number of directors or different
maximum and minimum numbers of directors by amendment of the Articles of
Incorporation or by a duly adopted amendment to these Bylaws. A majority of
the prescribed number of directors shall be necessary to constitute a quorum
for the trans- action of business. At a meeting at which a quorum is present,
every decision or act of a majority of the directors present made or done when
duly assembled shall be valid as the act of the Board of Directors, provided
that a minority of the directors, in the absence of a quorum, may adjourn from

remaining directors, though they be less than a quorum, and each director so
elected shall hold office until his successor is qualified following the
election at the next annual meeting of the shareholders or at any special
meeting of shareholders duly called for that purpose prior to such annual
meeting. A vacancy shall be deemed to exist in case the shareholders (or the
Board of Directors, within the provisions of Section 1 of this Article III)
shall increase the authorized number of directors, but shall fail, for a
period of thirty days from the effective date of such increase, to elect the
additional directors so provided for, or in case the shareholders fail at any
time to elect the full number of authorized directors. When one or more of the
                     
                                       3<PAGE>

directors shall give notice to the Board of Directors of his or their
resignation from said Board, effective at a future date, the Board of
Directors shall have the power to fill such vacancy or vacancies to take

SECTION 8.  NOTICE OF REGULAR AND SPECIAL MEETINGS OF THE DIRECTORS 

No notice shall be required to be given of any regular meeting of the Board of
Directors, but each director shall take notice thereof. Notice of each special
meeting of the Board of Directors shall be given to each of the directors by
mailing to each of them a copy of such notice at least five days prior to the
time affixed for such meeting to the address of such director as shown on the
books of the corporation. If his address does not appear on the books of the
corporation, then such notice shall be addressed to him at the principal
office of the corporation.  

SECTION 9.  WAIVER OF NOTICE

When all the directors of the corporation are present at any meeting of the
Board of Directors, however called or noticed, and sign a written consent
thereto on the record of such meeting, or if the majority of the directors are
present, and if those not present sign in writing a waiver of notice of such

meeting, whether prior to or after the holding of such meeting, which waiver
shall be filed with the Secretary of the corporation, the transactions of such
meeting are as valid as if had at a meeting regularly called and noticed.   

SECTION 10.  ACTION BY UNANIMOUS CONSENT OF DIRECTORS

Any action required or permitted to be taken by the Board of Directors may be
taken without a meeting if all members of the Board shall individually or
collectively consent in writing to such action. Such written consent or
consents shall be filed with the minutes of the proceedings of the Board, and
such action by written consent shall have the same force and effect as if
approved or taken at a regular meeting duly held. Any certificate or other
document which relates to action so taken shall state that the action was
taken by unanimous written consent of the Board of Directors without a
meeting, and that these Bylaws authorize the directors to so act.  

SECTION 11.  TELEPHONIC PARTICIPATION IN MEETINGS

Members of the Board may participate in a meeting through use of conference
telephone or similar communications equipment, so long as all members
participating in such meeting can hear one another. Participation in a meeting

SECTION 1.  Directors shall be reimbursed for their expenses, and shall be

fix by resolution. Nothing herein con- tained shall be construed to preclude

                                 ARTICLE VIII

                               INDEMNIFICATION

SECTION 1.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

Each person who was or is a party or is threatened to be made a party to or is
involved in any threatened, pending or completed action, suit or proceeding,
formal or informal, whether brought in the name of the corporation or
otherwise and whether of a civil, criminal, administrative or investigative
nature (hereinafter a "proceeding"), by reason of the fact that he or she, or
a person of whom he or she is the legal representative, is or was a director
or officer of the corporation or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation
or of a partnership, joint venture, trust or other enterprise, including
service with respect to employee benefit plans, whether the basis of such
proceeding is an alleged action or inaction in an official capacity or in any
other capacity while serving as a director or officer, shall, subject to the
terms of any agreement between the corporation and such person, be indemnified
and held harmless by the corporation to the fullest extent permissible under
California law and the corporation's Articles of Incorporation, against all
costs, charges, expenses, liabilities and losses (including attorneys' fees,
judgments, fines, ERISA excise tax or penalties and amounts paid or to be paid
in settlement) reasonably incurred or suffered by such person in connection
therewith, and such indemnification shall continue as to a person who has
ceased to be a director or officer and shall inure to the benefit of his or
her heirs, executors and administrators; provided, however, that (a) the
corporation shall indemnify any such person seeking indemnification in
connection with a proceeding (or part thereof) initiated by such person only
if such proceeding (or part thereof) was authorized by the Board of the
corporation, (b) the corporation shall indemnify such person seeking
indemnification in connection with a proceeding (or part thereof) other than a
proceeding by or in the name of the corporation to procure a judgment in its
favor only if any settlement of such a proceeding is approved in writing by
the corporation, and (c) that no such person shall be indemnified (i) except
to the extent that the aggregate of losses to be indemnified exceeds the
amount of such losses for which the director or officer is paid pursuant to
any directors' and officers' liability insurance policy maintained by the
corporation; (ii) on account of any suit in which judgment is rendered against

                                       7<PAGE>
<PAGE>                                       
                                       
such person for an accounting of profits made from the purchase or sale by
such person of securities of the corporation pursuant to the provisions of
Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto or
similar provisions of any federal, state or local statutory law; (iii) if a
court of competent jurisdiction finally determines that any indemnification
hereunder is unlawful; (iv) for acts or omissions involving intentional
misconduct or knowing and culpable violation of law; (v) for acts or omissions
that the director or officer believes to be contrary to the best interests of
the corporation or its shareholders or that involve the absence of good faith
on the part of the director or officer; (vi) for any transaction for which the
director or officer derived an improper personal benefit; (vii) for acts or
omissions that show a reckless disregard for the director's or officer's duty
to the corporation or its shareholders in circumstances in which the director
or officer was aware, or should have been aware, in the ordinary course of
performing his or her duties, of a risk of serious injury to the corporation
or its shareholders; (viii) for acts or omissions that constitute an unexcused
pattern of inattention that amounts to an abdication of the director's or
officer's duties to the corporation or its shareholders; (ix) for costs,
charges, expenses, liabilities and losses arising under Section 310 or 316 of
the General Corporation Law of California (the "Law"); and (x) as to
circumstances in which indemnity is expressly prohibited by Section 317 of the
Law. The right to indemnification conferred in this Article shall be a
contract right and shall include the right to be paid by the corporation
expenses incurred in defending any proceeding in advance of its final
disposition; provided, however, that if the Law requires the payment of such
expenses incurred by a director or officer in his or her capacity as a
director or officer (and not in any other capacity in which service was or is
rendered by such person while a director or officer, including, without
limitation, service to an employee benefit plan) in advance of the final
disposition of a proceeding, such advances shall be made only upon delivery to
the corporation of an undertaking, by or on behalf of such director or
officer, to repay all amounts to the corporation if it shall be ultimately
determined that such person is not entitled to be indemnified.

SECTION 2.  INDEMNIFICATION OF EMPLOYEES AND AGENTS  

A person who was or is a party or is threatened to be made a party to or is
involved in any proceedings by reason of the fact that he or she is or was an
employee or agent of the corporation or is or was serving at the request of
the corporation as an employee or agent of another enterprise, including
service with respect to employee benefit plans, whether the basis of such
action is an alleged action or inaction in an official capacity or in any
other capacity while serving as an employee or agent, may, subject to the
terms of any agreement between the corporation and such person, be indemnified
and held harmless by the corporation to the fullest extent permitted by
California law and the corporation's Articles of Incorporation, against all
costs, charges, expenses, liabilities and losses (including attorneys' fees,
judgments, fines, ERISA excise taxes or penalties and amounts paid or to be
paid in settlement), reasonably incurred or suffered by such person in
connection therewith.  The immediately preceding sentence is not intended to
be and shall not be considered to confer a contract right on any employee or
agent (other than directors and officers) of the corporation.

SECTION 3.  RIGHT OF DIRECTORS AND OFFICERS TO BRING SUIT

If a claim under Section 1 of this Article is not paid in full by the
corporation within 30 days after a written claim has been received by the
corporation, the claimant may at any time thereafter bring suit against the
corporation to recover the unpaid amount of the claim and, if successful in
whole or in part, the claimant shall also be entitled to be paid the expense
of prosecuting such claim. Neither the failure of the corporation (including
its Board, independent legal counsel, or its shareholders) to have made a
determination prior to the commencement of such action that indemnification of
the claimant is permissible in the circumstances because he or she has met the
applicable standard of conduct, if any, nor an actual determination by the
corporation (including its Board, independent legal counsel, or its
shareholders) that the claimant has not met the applicable standard of
conduct, shall be a defense to the action or create a presumption for the
purpose of an action that the claimant has not met the applicable standard of
conduct.

SECTION 4.  SUCCESSFUL DEFENSE

Notwithstanding any other provision of this Article, to the extent that a
director or officer has been successful on the merits or otherwise (including
the dismissal of an action without prejudice or the settlement of a proceeding
or action without admission of liability) in defense of any proceeding
referred to in Section 1 or in defense of any claim, issue or matter therein,
he or she shall be indemnified against expenses (including attorneys' fees)
actually and reasonably incurred in connection therewith.  

SECTION 5.  NON-EXCLUSIVITY OF RIGHTS

The right to indemnification provided by this Article shall not be exclusive
of any other right which any person may have or hereafter acquire under any
statute, bylaw, agreement, vote of shareholders or disinterested directors or
otherwise.

SECTION 6.  INSURANCE

The corporation may maintain insurance, at its expense, to protect itself and
any director, officer, employee or agent of the corporation or another
corporation, partnership, joint venture, trust or other enterprise against any
expense, liability or loss, whether or not the corporation would have the
power to indemnify such person against such expense, liability or loss under
the law.  

SECTION 7.  EXPENSES AS A WITNESS

To the extent that any director, officer, employee or agent of the corporation
is by reason of such position, or a position with another entity at the

                                       9<PAGE>
                                       
<PAGE>

request of the corporation, a witness in any action, suit or proceeding, he or
she shall be indemnified against all costs and expenses actually and
reasonably incurred by him or her on his or her behalf in connection
therewith.

SECTION 8.  INDEMNITY AGREEMENTS

The corporation may enter into agreements with any director, officer, employee
or agent of the corporation providing for indemnification to the fullest
extent permissible under the law and the corporation's Articles of
Incorporation.

SECTION 9.  SEPARABILITY

Each and every paragraph, sentence, term and provision of this Article is
separate and distinct so that if any paragraph, sentence, term or provision
hereof shall be held to be invalid or unenforceable for any reason, such
invalidity or unenforceability shall not affect the validity or
unenforceability of any other paragraph, sentence, term or provision hereof.
To the extent required, any paragraph, sentence, term or provision of this
Article may be modified by a court of competent jurisdiction to preserve its
validity and to provide the claimant with, subject to the limitations set
forth in this Article and any agreement between the corporation and claimant,
the broadest possible indemnification permitted under applicable law.

SECTION 10.  EFFECT OF REPEAL OR MODIFICATION

Any repeal or modification of this Article shall not adversely affect any
right of indemnification of a director or officer existing at the time of such
repeal or modification with respect to any action or omission occurring prior
to such repeal or modification."

                                  ARTICLE IX

Officer) shall act in his place and perform his duties; if the President or
next most senior officer is unable to perform such duties, then the vice
presidents, in such sequence as the Board of Directors may specify, shall act.
If all the foregoing shall be unable to act, the senior officer among them
shall appoint some other person in whom shall be vested, for the time being,

absence) over all meetings of the shareholders and directors;

2.  Sign in behalf of the corporation contracts and other instruments in
writing within the scope of his authority or if, when, and as directed so to
do by the Board of Directors, but nothing herein shall limit the power of the
Board of Directors to authorize such contracts and other instruments in
writing to be signed by any other officer or person or limit the power of the
Chief Executive Officer to delegate his authority in any such matter to
another officer or other officers of the corporation. The Chief Executive
Officer or any other officer specified by the Board of Directors may sign

required to be done by him, may with like effect be given or served or done by
or under the direction of an Assistant Secretary;  
 
3.  The Secretary shall discharge such other duties as pertain to his office
or which may be prescribed by the Board of Directors.
