(1)  BASIS OF PRESENTATION

     The accompanying financial statements present the consolidated accounts of
Mobley Environmental Services, Inc. (the "Company") and its subsidiaries.  All
significant intercompany accounts and transactions have been eliminated.

     The unaudited consolidated financial statements reflect all adjustments
which are, in the opinion of management, of a normal and recurring nature and
necessary for a fair presentation of the consolidated financial position of the
Company as of June 30, 1998, and the consolidated results of operations and cash
flows for the periods presented herein.  Interim results are not necessarily
indicative of results for a full year.  The unaudited consolidated financial
statements should be read in conjunction with the consolidated financial
statements and notes thereto presented in the Company's Annual Report on Form
10-K for the year ended December 31, 1997.

     Management of the Company has made a number of estimates and assumptions
relating to the reporting of assets and liabilities and the disclosure of
contingent liabilities to prepare these financial statements in accordance with
generally accepted accounting principles.  Actual results could differ from
those estimates.

(2)  1997 ASSET SALES AND DISCONTINUED OPERATIONS

     During 1997, the Company sold substantially all of its operating assets in
two separate transactions.  The transactions and their impact on the Company's
consolidated financial statements are described in the following paragraphs.

     SALE OF WASTE MANAGEMENT SERVICES ASSETS AND DISCONTINUANCE OF BUSINESS
SEGMENT.  On May 29, 1997, the Company sold substantially all of the assets
related to its waste management services activities to United States Filter
Corporation ("USF").  As a result of that transaction, the Company received
$8,000,000 in shares of USF common stock (registered with the Securities and
Exchange Commission) in exchange for such assets, and can earn up to an
additional $4,000,000 in USF common stock based on the performance of the
business during the two years following its sale.  As of May 29, 1998,
approximately 20% of the earnout was achieved and 28,294 shares of U.S. Filter
stock was received for the first year of operations subsequent to closing the
sale.  The fair value of the 28,294 shares at June 30, 1998 was approximately
$794,000, which has been reported as a gain from discontinued operations for the
six month period ended June 30, 1998.  Additionally, USF assumed certain
liabilities (accounts payable and accrued expenses) as part of the transaction. 
The net assets which were the subject of this transaction have been removed from
the consolidated balance sheet as of December 31, 1997.  Such assets had a net
book value (net of assumed liabilities) of approximately $14,965,060.

     During the year ended December 31, 1996, the Company recorded a charge of
$7,621,000 (net of a deferred income tax benefit of $698,000), representing the
estimated loss on the disposal of the business segment, including certain
required capital expenditures prior to the sale amounting to approximately

portion of the sales price was considered (I.E., that portion which is
contingent on the future performance of the business was ignored).  Such loss
was recognized in the third quarter of 1996, when it was determined that a sale
of the assets was necessary given the Company's inability to secure acceptable
financing and concerns about its liquidity.  Prior to that time, the evaluation
of potential asset impairment had been made on a "going concern" basis and cash
flow projections for the segment supported the carrying values of the related
assets.  The Company estimated that it would incur additional operating losses
in this business segment, after the allocation of certain overhead and interest
costs, amounting to approximately $331,000 during the phase-out period from
October 1, 1996 to May 29, 1997.  A provision for such estimated net losses was
made during the year ended December 31, 1996.  The Company's waste management
services segment reported a net loss of approximately $405,000 during the period
from January 1, 1997 until May 29, 1997, the date of closing on the sale, which
was in excess of the amounts previously accrued.  The majority of the loss was
created by additional charges related to automobile liability insurance claims
and medical claims which were not included in the accruals established at
December 31, 1996.  

     On July 21, 1995, the Company acquired, pursuant to an asset purchase
agreement dated June 7, 1995, certain assets of a group of three affiliated
companies, including Romero Brothers Oil Exchange, Inc., Environmental Petroleum
Products Co./EPPCO, and Environmental Insight, Inc.  The asset purchase was
effectuated through a newly-formed, wholly-owned subsidiary of the Company, HTI
(Waste Management Services Segment).  The Romero brothers had the right to earn
shares in the Company based on the profitability of the acquired companies. 
This right was suspended due to the sale of the waste management services
segment.  In order to settle this obligation and to offer the Romero brothers an
incentive to remain with the business to maximize the Company's earnout, the
Company paid the Romero brothers approximately $115,000 in June 1998.  This
payment had not been accrued and was recorded as a loss from discontinued
operations.  In addition, the Romero brothers are to receive a percentage of the
Company's earnout with US Filter.  Approximately $72,500 is to be paid to the
Romero brothers during the third quarter of 1998 resulting from the earnout with
US Filter that was achieved as of May 29, 1998 for the first year of operations
subsequent to closing the sale of the waste management services segment.  The
payment has been accrued as of June 30, 1998 and is reported as a loss from
discontinued operations.  

     SALE OF OILFIELD SERVICES ASSETS AND DISCONTINUANCE OF BUSINESS SEGMENT. 
On January 20, 1997, the Company sold substantially all of the assets related to
its oilfield services business to Dawson Production Services, Inc. ("Dawson"). 
As a result of this transaction, the Company received approximately $4,917,000
and a subordinated note in the amount of $500,000, due in January 2002, in
exchange for such assets.  This note was paid in full during the fourth quarter
of 1998.  The assets which were the subject of the sale had a net book value,
based on historical cost adjusted for accumulated depreciation and amortization,
of approximately $2,354,000.  The results of operations associated with the
discontinued segment through the disposal date, after allocation of certain
overhead and interest costs, did not result in a loss.  The Company's oilfield
services segment generated net income of approximately $120,000 during the
period October 1, 1996 to January 20, 1997.  The Company recognized a gain upon
completion of the sale, after transaction costs of approximately $261,000,
amounting to approximately $2,802,000 in January 1997.

                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   JUNE 30, 1998
                                    (unaudited)
                                          

     Because of the outstanding contractual indemnification obligations of the
Company resulting from its business divestitures and in light of pending
litigation to which the Company is a party, the Company will remain in existence
and incur certain general and administrative expenses for the foreseeable future
but will have no operating assets.  Therefore, certain general and
administrative expenses and nonoperating income and expense have been accounted
for as continuing operations.  Future costs incurred in connection with these
indemnification obligations and litigation responsibilities will be reported as
part of the discontinued operations in which they originated or to which they
related.  The Company believes it is probable that it will continue to incur
certain costs associated with these legal matters and accordingly established an
accrual for estimated out-of-pocket expenses related to the ongoing
administrative management of such matters.  However, the Company is currently
unable to reasonably estimate its potential exposure for defending such matters,
any indemnity obligations resulting therefrom, and any corresponding insurance
reimbursement (note 7).

     The Company's two business segments, waste management services and oilfield
services, were accounted for as discontinued operations during 1997 and 1998,
and accordingly, their operations for the six months ended June 30, 1997 and
1998 have been segregated in the accompanying consolidated statements of
operations.  The revenues, operating costs and expenses, and income taxes for
the period ended June 30, 1997, has been reclassified for amounts associated
with the discontinued segments.  Due to the relative significance of the
Company's business segments to its operations as a whole, and in light of the
Company's decision in 1996 to divest itself of all of its operating assets, the
Company allocated certain general and administrative expenses to the business
segments for the six months ended June 30, 1997 in the accompanying consolidated
segments of operations.  General and administrative expenses attributable to
continuing operations were determined based upon an allocation of such costs
between the business segments and continuing operations.   Other income and
expense were recorded as continuing operations as such amounts are not
specifically attributable to either of the Company's business segments which
were disposed of.  Interest expense was allocated to the segments based on the
outstanding indebtedness attributable to each of the business segments.

     Operating results of the Company's waste management services segment for
the period ended June 30, 1997, were as follows (in thousands of dollars):

     At June 30, 1998, the Company has net operating loss carryforwards for
federal income tax purposes of approximately $6,000,000.  Such amounts are
available to offset future Federal taxable income, if any, through 2012 and
expire in the following years:  2009 - approximately $1,700,000; 2010 -
approximately $1,200,000; 2011 - approximately $2,200,000 and 2012 -
approximately $900,000.  

     Upon completion of the sale of the waste management services segment, the
$8,000,000 of USF common stock was sold.  Proceeds from this sale were used to
pay off existing long-term debt and current liabilities, and the remaining
proceeds were used to purchase investment grade fixed term securities.  These
investments are accounted for as investments available for sale.  As of December
31, 1997, approximately $825,000 in investments was held in escrow until May 29,
1998 to satisfy any indemnification obligations of the Company to U.S. Filter. 
As of May 29, 1998, approximately $500,000 were released from escrow.  In an
agreement dated September 25, 1998 with U.S. Filter, an additional $55,000 was
released from escrow, with all other funds being remitted to U.S. Filter.

     The Company had a credit agreement (the "Credit Agreement") that provided
up to $6,500,000 in available credit for the Company.  In connection with the
closing of the sale of the Company's oilfield services segment in January 1997,
the Company repaid $3,300,000 of outstanding indebtedness under the Credit

(5)  EARNINGS PER SHARE

     In February 1997, the Financial Accounting Standards Board issued SFAS 128,
EARNINGS PER SHARE.  SFAS 128 supersedes the earnings per share calculation
methods of APB 15, effective for annual and interim periods ending after
December 15, 1997.  In accordance with this standard, earnings per share ("EPS")
amounts presented on the Company's Consolidated Statements of Operations have
been calculated using the measurement provisions of SFAS 128.  Basic earnings
per share is computed based on earnings available to common shareholders and the
weighted average number of common shares outstanding.  The earnings per share
assuming dilution amounts presented are computed based on earnings available to
common shareholders and the weighted average number of common shares
outstanding, including shares assumed to be issued under the Company's 1995
Employee Restricted Stock Plan.  The implementation of SFAS 128 had no impact on
earnings per share.  

     The following data shows amounts used in computing earnings per share under
the provisions of SFAS 128:  (In thousands, except per share amounts and share
data).

(7)  COMMITMENTS AND CONTINGENCIES

     LETTERS OF CREDIT.  At June 30, 1998, letters of credit totaling
approximately $1,012,000 had been provided by the Company to its insurance
carrier in connection with its workers' compensation, general liability, and
auto liability insurance policies.  

     LITIGATION AND VARIOUS OTHER CLAIMS.  The Company continues to defend
various claims resulting from the operations of its former subsidiary,
Gibraltar, which was sold effective December 31, 1994.  As of October 2, 1998,
four such lawsuits were pending.  During the Company's ownership of Gibraltar,
Gibraltar engaged in the collection, transportation, analysis, treatment
management and disposal of various types of hazardous wastes.  In the actions
pending against the Company and/or Gibraltar, the plaintiffs complain of a
variety of acts by Gibraltar which allegedly occurred in the course of its
operations, including improper air emissions, nuisance odors, contamination of
water supplies, and repeated and continuing violations of environmental laws. 
In the various pending actions, plaintiffs assert similar theories as the
alleged basis for recovery, including negligence, nuisance, trespass, fraudulent
concealment, assault and battery, and intentional infliction of emotional
distress.  Likewise, the various plaintiffs in pending actions seek similar
types of damages, including loss of property value and compensatory and punitive
damages for personal injury and property damage for nuisance odors, physical
discomfort and impairment, interference with use and enjoyment of property,
medical expenses, mental anguish, and loss of earning capacity.  An additional
claimant seeks permanent closure of the facility and civil penalties as the
remedy for alleged violations by Gibraltar of environmental protection statutes
and endangerment to public health and the environment.  While all of the four
actions are technically pending, one case was dismissed by the trial judge for
plaintiff's failure to file expert reports as required by a case management
order.  This action has been appealed.  

     These matters raise difficult and complex factual and legal issues,
including but not limited to, the nature and amount of the Company's liability,
if any.  Although the Company is a defendant in some litigation, in other
matters the Company's potential liability arises from material contractual
indemnifications given by the Company to the purchaser of Gibraltar.  In
particular, in connection with the sale of Gibraltar, the Company made extensive
representations and warranties regarding Gibraltar.   The Company is required to
indemnify AEC for all losses resulting from breaches of representations and
warranties and pending or future claims or proceedings resulting from
circumstances existing prior to closing.  The terms of the stock purchase
agreement between AEC and the Company provided that such indemnification
obligations would extend through June 30, 1996 (or in the case of tax,
environmental and ERISA claims, through June 30, 1998).  However, the Company
and AEC have executed a Tolling Agreement dated July 30, 1997, pursuant to which
the statute of limitations period for certain potential claims by either party
against the other has been tolled from July 30, 1997 through July 30, 2000. 
These indemnifications may include the potential liability of former customers
of Gibraltar, approximately 50 of which have also become defendants in
litigation involving Gibraltar's operations.

                     NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                    (unaudited)
                                          

     The Company has been notified by its insurance carrier that it disputes the
Company's interpretation of its pollution liability insurance coverage and
policy limitations applicable to the foregoing claims.  While the Company is
vigorously pursuing a favorable resolution of this dispute, it is unable to
determine the likelihood of an unfavorable outcome at this time.

     The Company, based on consultation with its legal counsel, believes that 
it is probable that the Company will continue to incur certain costs 
associated with the foregoing matters and accordingly, in connection with the 
divestiture of Gibraltar in 1994, established an accrual for estimated 
out-of-pocket expenses related to the ongoing administrative management of 
such matters.  However, the Company is currently unable to reasonably 
estimate its potential exposure for defending such matters, any indemnity 
obligations resulting therefrom, and any corresponding insurance 
reimbursement.  As noted above, the litigation matters to which the Company 
is a party raise several difficult and complex factual and legal issues.  
More specifically: (i) while certain of the plaintiffs exhibit apparent 
physical injury and a variety of health problems, the requisite causal 
connection to Gibraltar's facilities or operations has not been established; 
(ii) certain of the cases involve literally hundreds of plaintiffs whose 
physical condition and medical history have not yet begun to be investigated; 
(iii) although the Company has experienced some degree of success recently in 
two separate jury trials, there is inherent uncertainty associated with jury 
trials in cases such as these which tend to have a strong emotional appeal; 
(iv) the extent of pollution liability insurance coverage available to the 
Company for potential indemnity exposure and defense costs is currently in 
dispute; (v) the Company's potential liability relating to defense cost 
claims of approximately 50 of Gibraltar's former customers who have also been 
named in the litigation (and who are represented by over 20 different law 
firms) is currently not determinable; and (vi) the indemnifications given to 
AEC in connection with the Gibraltar sale are comprehensive and subject to 
broad interpretation.  Accordingly, the Company has not made an accrual for 
losses, if any, which might result from these legal matters as such amounts 
or a range of amounts are not currently reasonably estimable.  The Company's 
future financial condition, results of operations, and liquidity could be 
materially adversely affected as the nature and scope of the Company's 
ultimate liability arising from Gibraltar's operations and sale become better 
defined.

     In January 1996, the Company was notified by the TNRCC that it was a 
potentially responsible party of the alleged release, during the early or 
mid-1980s, of hazardous substances at the McBay Oil and Gas State Superfund 
Site located near Grapeland, Texas.  During 1997, the Company entered into a 
contractual remediation plan for this site and paid the contract amount.  
Such plan did not have a material affect on the consolidated financial 
statements. However, completion of the remediation and final resolution of 
the matter is subject to approval of the TNRCC.  

     There are various other routine claims and legal actions pending and 
threatened against the Company which are incidental to the Company's business 
and have arisen in the ordinary course of its business related to services, 
contracts, employment, and other matters.  Where applicable, the Company has 
recorded accruals for estimated potential damages and expenses associated 
with such matters.  While the final outcome of these matters cannot be 
predicted with certainty, management upon consultation with legal counsel, 
and considering the Company's limited continuing activities, believes that 
financial obligations of the Company arising from such claims could have a 
material adverse effect on its consolidated financial condition, results of 
operations, or liquidity.

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

GENERAL

     Prior to May 29, 1997, the Company's business involved providing diverse 
environmental and field-related services to industrial, governmental, and 
commercial markets, specializing in the collection, transportation, 
treatment, recycling and management of a wide variety of non-hazardous liquid 
hydrocarbons, oil filters, absorbents and related materials.  Additionally, 
prior to January 20, 1997, through its oilfield services segment, the Company 
provided services for managing liquids used or produced during the life cycle 
of oil and gas wells.

     The following discussion is designed to assist in the understanding of the
Company's financial condition as of June 30, 1998, as well as the Company's
operating results for the six-month period ended June 30, 1998.  Certain
material events affecting the business of the Company are discussed in Item 1 of
this report.  The Notes to Consolidated Financial Statements contain additional
information that should be read in conjunction with this discussion.  

1997 ASSET SALES, DISCONTINUED OPERATIONS AND RESTRUCTURING CHARGES

     On January 20, 1997 and May 29, 1997, the Company completed transactions
pursuant to which it sold substantially all of its operating assets in two
separate transactions (see Note 2 of Notes to Consolidated Financial
Statements).  Because of these sales, results of operations of the Company's two
business segments for the six months ended June 30, 1997 and 1998, have been
accounted for as discontinued operations in the accompanying consolidated
financial statements.  The transactions and their impact on the consolidated
financial statements are described in the following paragraphs.  

     SALE OF WASTE MANAGEMENT SERVICES ASSETS & DISCONTINUANCE OF BUSINESS
SEGMENT.  On May 29, 1997, the Company sold substantially all of the assets
related to its waste management services activities to United States Filter
Corporation ("USF").  As a result of that transaction, the Company received $8.0
million in shares of USF common stock (registered with the Securities and
Exchange Commission) in exchange for such assets, and can earn up to an
additional $4.0 million in USF common stock based on the performance of the
business during the two years following its sale.  As of May 29, 1998,
approximately 20% of the earnout was achieved and 28,294 shares of U.S. Filter
stock was received for the first year of operations subsequent to closing the
sale.  The fair value of the 28,294 shares at June 30, 1998 was approximately
$794,000, which has been reported as a gain from discontinued operations for the
six month period ended June 30, 1998.  Additionally, USF assumed certain
liabilities (accounts payable and accrued expenses) as part of the transaction. 
The net assets which were the subject of this transaction have been removed from
the consolidated balance sheet as of December 31, 1997.  Such assets had a net
book value (net of assumed liabilities) of approximately $14,965,060.  

     During the year ended December 31, 1996, the Company recorded a charge of
$7,621,000 (net of a deferred income tax benefit of $698,000), representing the
estimated loss on the disposal of the business segment including certain
required capital expenditures prior to the sale.  In determining the estimated
loss on disposal, only the $8.0 million guaranteed portion of the sales price
was considered (i.e., that portion which is contingent on the future performance
of the business was ignored).  The Company estimated that it would incur
additional operating losses in this business segment after the allocation of
certain overhead and interest costs, amounting to approximately $331,000 during
the phase-out period from October 1, 1996 to May 1997.  A provision for such
estimated net losses was made during the year ended December 31, 1996.  The
Company's waste management services segment reported a net loss of approximately
$405,000 during the period from January 1, 1997 until May 29,  

                                         13

1997, the date of closing on the sale, which was in excess of the amounts
previously accrued.  The majority of the loss was created by additional charges
related to automobile liability insurance claims and medical claims which were
not included in the accruals established at December 31, 1996.  

     On July 21, 1995, the Company acquired, pursuant to an asset purchase
agreement dated June 7, 1995, certain assets of a group of three affiliated
companies, including Romero Brothers Oil Exchange, Inc., Environmental Petroleum
Products Co./EPPCO, and Environmental Insight, Inc.  The asset purchase was
effectuated through a newly-formed, wholly-owned subsidiary of the Company, HTI
(Waste Management Services Segment).  The Romero brothers had the right to earn
shares in the Company based on the profitability of the acquired companies. 
This right was suspended due to the sale of the waste management services
segment.  In order to settle this obligation and to offer the Romero brothers an
incentive to remain with the business to maximize the Company's earnout, the
Company paid the Romero brothers approximately $115,000 in June 1998.  This
payment had not been accrued and was recorded as a loss from discontinued
operations.  In addition, the Romero brothers are to receive a percentage of the
Company's earnout with US Filter.  Approximately $72,500 is to be paid to the
Romero brothers during the third quarter of 1998 resulting from the earnout with
US Filter that was achieved as of May 29, 1998 for the first year of operations
subsequent to closing the sale of the waste management services segment.  The
payment has been accrued as of June 30, 1998 and is reported as a loss from
discontinued operations.  

     SALE OF OILFIELD SERVICES ASSETS AND DISCONTINUANCE OF BUSINESS SEGMENT. 
On January 20, 1997, the Company sold substantially all of the assets related to
its oilfield services business to Dawson Production Services, Inc. ("Dawson"). 
As a result of that transaction, the Company received approximately $4,917,000
and a subordinated note in the amount of $500,000 due in January 2002 in
exchange for such assets.  This note was paid in full during the fourth quarter
of 1998.  The assets which were the subject of the sale had a net book value,
based on historical cost adjusted for accumulated depreciation and amortization,
of approximately $2,354,000.  The results of operations associated with the
discontinued segment through the disposal date, after allocation of certain
overhead and interest costs, did not result in a loss.  The Company recognized a
gain upon completion of the sale, after transaction costs of approximately
$261,000, amounting to approximately $2,802,000 in January 1997.

RESULTS OF OPERATIONS

     General and administrative expenses amounted to $206,000 and $164,000 for
the three months ended June 30, 1998 and 1997, respectively, and $365,000 and
$322,000 for the six months ended June 30, 1998 and 1997, respectively.  These
costs represent the ongoing administrative costs of the Company after disposing
all of its operating assets.  Interest income of $102,000 and $180,000 was
earned in the three month and six month period ended June 30, 1998,
respectively, on the investments available for sale and note receivable.  There
was no significant interest income earned for the three month and six month
period ended June 30, 1997 because the investment securities were not received
until May 29, 1997 as a result of the sale of the waste management services
business segment.  In addition, a gain on the sale of US Filter shares in the
amount of $531,000 was recorded in the second quarter of 1997 when substantially
all of the US Filter stock was sold.  

     Income from discontinued operations amounted to $2,397,000 for the six
month period ended June 30, 1997.  The $607,000 in income from discontinued
operations for the three month and six month period ended June 30, 1998 is
comprised of the $794,000 in US Filter stock received and approximately $115,000
cash paid and $72,500 to be paid to the Romero brothers resulting from the sale
of the waste management services segment.   

                                      14

CAPITAL RESOURCES AND LIQUIDITY

     All of the $8.0 million in U.S. Filter common stock received at the time of
the closing of the sale of its waste management services assets has been sold. 
Cash from the USF stock sale, along with the proceeds from the sale of the
oilfield services assets, resulted in net proceeds totaling approximately $8.2
million after repayment of the outstanding bank indebtedness and transaction
expenses.  Such net proceeds were used to fund the current liabilities retained
by the Company following the sales, with the remaining surplus cash deployed in
investment securities. General and administrative expenses incurred for the six
month period ended June 30, 1998 were $365,000.  The Company anticipates that
ongoing general and administrative expenses will be approximately $540,000
annually, exclusive of any litigation costs, and expects earnings from
investments to partially offset such costs. The amounts described herein are
approximate and based on the Company's current estimates.  Furthermore, there
can be no assurance that such amounts will actually be realized.

     In addition to the aforementioned proceeds, under the terms of the asset 
purchase agreement with U.S. Filter, the Company may receive up to $4.0 
million in USF common stock during the two-year period following the sale 
based on the performance of the hydrocarbon recycling business.  As of May 
29, 1998, approximately 20% of the earnout was achieved and 28,294 shares of 
U.S. Filter stock was received for the first year of operations subsequent to 
closing the sale.  The fair value of the 28,294 shares at June 30, 1998 was 
approximately $794,000, which has been reported as a gain from discontinued 
operations for the six month period ended June 30, 1998.  Additionally, in 
connection with the sale of the oilfield services business, the Company 
received a $500,000 subordinated note receivable from Dawson, bearing 
interest at 8.5%, which matures on January 4, 2002.  This note was paid in 
full during the fourth quarter of 1998.  

     In connection with the sale of assets to U.S. Filter, 10% of the proceeds
of such transaction (approximately $825,000) were required to be maintained in
escrow for a period of one year from the closing of the transaction to satisfy
indemnification obligations of the Company to U.S. Filter.  On May 29, 1998,
approximately $500,000 were released from escrow and paid to the Company.  In an
agreement dated September 25, 1998 with U.S. Filter, an additional $55,000 was
released from escrow and paid to the Company with all other funds being remitted
to U.S. Filter.  

     Because of its indemnification obligations related to the sale of
Gibraltar, as well as potential indemnity obligations with respect to the asset
sales to USF and Dawson, and in light of the ongoing litigation (described in
the Company's Annual Report on Form 10-K for the year ended December 31, 1997),
the Company, based on consultation with legal counsel, does not currently
anticipate making a distribution to its stockholders in the foreseeable future. 
As circumstances change or additional information with respect to the extent of
the Company's potential indemnity obligations becomes available, the Board of
Directors will continue to evaluate various uses of the Company's funds.  The
Company has no plans to conduct any kind of operating business at any time in
the future.
