2.  Earnings per Common Share

Subsequent to the issuance of the Company's 1999 consolidated financial
statements, the Company's management determined that for purposes of the
calculation of earnings per common share, the exchangeable non-voting shares of
LaSalle Re are not considered to be outstanding common shares of the Company. As
a result, earnings per common share and earnings per common share - assuming
dilution have been restated from the amounts previously reported. The
exchangeable non-voting shares have been removed from the calculation of
weighted average number of common shares but the dilutive effect has been
included in the adjusted weighted average number of common shares outstanding.

The following earnings per Common Share have been disclosed in accordance with
the requirements of SFAS 128:

antidilutive effect on losses per Common Share.

As of March 31, 2000, the Company had 1,022,514 options outstanding and had
granted 340,872 stock appreciation rights.  As of March 31, 1999, the Company
had 1,086,114 options outstanding and had granted 340,872 stock appreciation
rights.

              Management's Discussion and Analysis of Operations
                            and Financial Condition
--------------------------------------------------------------------------------

The following is a discussion and analysis of the Company's results of
operations for the three months and six months ended March 31, 2000 and 1999 and
financial condition as of March 31, 2000 and September 30, 1999. This discussion
and analysis should be read in conjunction with the attached unaudited
consolidated financial statements and notes thereto of the Company and the
audited consolidated financial statements and notes thereto contained in the
Company's Annual Report on Form 10-K for the fiscal year ended September 30,
1999.

General

The Company primarily writes property catastrophe reinsurance on a worldwide
basis through its subsidiary, LaSalle Re. Property catastrophe reinsurance
contracts cover unpredictable events such as hurricanes, windstorms, hailstorms,
earthquakes, fires, industrial explosions, freezes, riots, floods and other man-
made or natural disasters. Therefore, there can be significant volatility in the
Company's results from fiscal quarter to quarter and fiscal year to year.
Through LaSalle Re Capital, the Company also provides capital support to
selected Lloyd's syndicates which individually write the following lines of
business: direct and facultative property insurance; marine reinsurance; and
professional indemnity, directors and officers insurance and bankers blanket
bond business. Due to the nature of the business written by the Company, the
financial data included herein is not necessarily indicative of the results of
operations or financial condition of the Company in the future.

On December 19, 1999, the Company announced that it had entered into a
definitive agreement to combine with Trenwick Group Inc., with shareholders of
each company to receive shares in a new Bermuda holding company to be named
Trenwick Group Ltd.  This transaction is expected to be completed late in the
second quarter or early in the third quarter of calendar 2000.

Results of Operations - for the three months ended March 31, 2000 and 1999

Gross premiums written for the quarter ended March 31, 2000 were $65.2 million
compared to $88.6 million for the quarter ended March 31, 1999, a decrease of
$23.4 million or 26.4%.

The Company's property catastrophe book experienced a reduction in gross
premiums written of $20.2 million for the quarter ended March 31, 2000 compared
to the quarter ended March 31, 1999.  Of this reduction, approximately $15.0
million related to reduced premium writings on international pro rata treaties.
This reduction is consistent with the Company's plan of placing an emphasis on
accessing clients directly rather than through pro rata  catastrophe contracts,
which have a less efficient cost structure. In addition, the Company experienced
a reduction in its international direct business of approximately $6.0 million.
This related to renewal business which incepted in the first calendar quarter of
1999 and was renewed primarily on a fifteen month basis to avoid Year 2000
issues. Most of this premium will now be up for renewal in the second calendar
quarter of 2000.

For the quarter ended March 31, 2000, gross premiums written in lines of
business other than property catastrophe totaled $9.9 million compared to $11.6
million for the quarter

ended March 31, 1999. The decrease is principally reflective of reduced marine
exposures with a significant pro rata marine treaty written in 1999 not
available for renewal in 2000.

Gross premiums written by LaSalle Re Capital were comparable at $6.8 million for
the quarter ended March 31, 2000 and $6.0 million for the quarter ended March
31, 1999.

During the quarter ended March 31, 2000, the Company experienced negative
premium adjustments of $1.1 million compared to positive premium adjustments of
$3.6 million for the quarter ended March 31, 1999. These adjustments are
primarily due to the revision of premium estimates on pro rata property
catastrophe contracts following the receipt of updated information from cedents.
In addition, the Company recorded an increase in the level of reinstatement
premiums of $1.6 million due to increased loss activity.

Premiums ceded for the quarter ended March 31, 2000 were consistent with the
level for the quarter ended March 31, 1999 at $16.7 million compared to $16.5
million, respectively.

Net premiums written for the quarter ended March 31, 2000 were $48.5 million
compared to $72.2 million for the quarter ended March 31, 1999.

Net premiums earned for the quarter ended March 31, 2000 were $27.2 million
compared to $38.1 million for the same quarter in 1999. The decrease of $10.9
million or  28.6% was principally caused by two factors: a reduction in gross
premiums written from calendar year 1999 to calendar year 2000 and an increase
in the level of ceded premiums amortized. For the quarter ended March 31, 2000,
ceded premiums amortized were $7.2 million compared to $2.5 million for the
quarter ended March 31, 1999.

Net investment income remained consistent at $8.9 million for the quarter ended
March 31, 2000 compared with $8.8 million for the quarter ended March 31, 1999.
Annualized investment income as a percentage of the average market value of
invested assets was 6.3% for the quarter ended March 31, 2000 compared to 5.8%
for the quarter ended March 31, 1999.

Net realized losses on investments were $2.2 million during the quarter ended
March 31, 2000 compared with net realized losses of $0.6 million during the
quarter ended March 31, 1999. The losses in the quarter ended March 31, 2000
related primarily to the sale of longer maturity government agency bonds, a
policy designed to protect the total returns on the portfolio.

The following table sets forth the Company's combined ratios for the quarters
March 31, 2000 and 1999:

                                     March 31, 2000       March 31, 1999
                              -------------------------------------------------
Loss and loss expense ratio             160.0%                 131.9%
Expense ratio                            30.4%                  22.9%

--------------------------------------------------------------------------------

Losses and loss expenses incurred represent losses paid and reserves established
in respect of specific losses and loss expenses reported by cedents and expected
loss development and additions to incurred-but-not-reported loss reserves.

The Company incurred net losses and loss expenses of $43.5 million during the
quarter ended March 31, 2000 compared with $50.2 million during the quarter
ended March 31, 1999. The Company reserved $15.0 million for losses relating to
events that occurred during the quarter, these included the Arkansas storms in
January 2000.  Other significant movements in incurred net losses include an
increase of $17.5 million relating to Storm Martin that hit France in late 1999.
This follows an increase in the market estimate of the loss. The Company has
estimated the size of the market loss at $3.6 billion, an increase of 200% from
early 2000.  This magnitude of loss assumes full limit losses on all French
specific contracts and a conservative reserve for non-specific contracts. Also,
following notification from a syndicate supported by LaSalle Re Capital, during
the quarter ended March 31, 2000; the Company has recorded $7.4 million for loss
reserves. These losses relate to a particular program that was underwritten by
the syndicate in 1997 through to 1999. The loss reserves recorded by the Company
represent the potential full liability for losses from this program. In
addition, the Company has strengthened it's loss reserves for the Danish storm
which occurred in early December 1999, by $5.5 million following evidence of an
increase in the market loss.

During the quarter ended March 31, 1999, the Company incurred losses on the
tornadoes that hit the mid-western states of the United States in January 1999.
In addition to these claims and the establishment of reserves for other events
that occurred during the quarter but had not been reported, the Company
strengthened prior year reserves. During the quarter ended March 31, 1999, the
Company recorded approximately $14 million of additional case reserves for large
losses reported during the quarter and an additional $20 million of incurred-
but-not-reported loss reserves, following a review of the assumptions used in
setting incurred-but-not-reported loss reserves.

The expense ratio includes underwriting expenses and operational expenses.
Underwriting expenses include brokerage, commissions, excise taxes and other
costs related to underwriting reinsurance contracts.

Underwriting expenses as a percentage of net earned premiums were 18.7% for the
quarter ended March 31, 2000 compared to 16.6% for the quarter ended March 31,
1999. The increase in the ratio of 2.1% was due to the increased amount of
amortized ceded reinsurance that reduced net premiums earned. For the quarter
ended March 31, 2000 underwriting expenses as a percentage of gross premiums
earned were 14.8% compared to 15.5% for the quarter ended March 31, 1999.

Operational expenses were $3.2 million for the quarter ended March 31, 2000
compared to $2.4 million for the quarter ended March 31, 1999. As a percentage
of net premiums earned, operational expenses were 11.7% during the quarter ended
March 31, 2000 compared to 6.3% for the quarter ended March 31, 1999. The
increase in operational expenses of $0.8 million was principally due to an
increase in the level of executive compensation booked in connection with an
outstanding grant of stock appreciation rights. During the quarter ended March
31, 2000, the Company had a credit of $0.2

million in respect of stock appreciation rights compared to a credit of $0.6
million during the quarter ended March 31, 1999.

Corporate expenses were $0.5 million for the quarter ended March 31, 2000. These
expenses related primarily to the business combination agreement with Trenwick
Group Inc. For the quarter ended March 31, 1999 corporate expenses were $0.2
million and related to the preparation and filing of a registration statement
for an offering of preferred shares which was subsequently withdrawn prior to
becoming effective.

Interest expense remained consistent at $0.3 million for the quarter ended March
31, 2000 compared with $0.4 million in the quarter ended March 31, 1999.
Interest expense included financing charges associated with the deposit portion
of LaSalle Re's ceded reinsurance contract and other interest expenses related
to the ongoing commitment fees payable on the Company's credit facility. As at
March 31, 2000, there were no borrowings under this facility.

The Company's loss per share, both basic and diluted, was $0.99 for the quarter
ended March 31, 2000 compared to a loss per share of $0.76 for the quarter ended
March 31, 1999.

Results of Operations - for the six months ended March 31, 2000 and 1999

Gross premiums written for the six months ended March 31, 2000 were $75.5
million compared to $100.4 million for the six months ended March 31, 1999, a
decrease of $24.9 million or 24.8%.

The Company's property catastrophe book experienced a reduction in gross
premiums written of $19.9 million for the six months ended March 31, 2000
compared to the six months ended March 31, 1999. Of this reduction approximately
$15.0 million related to reduced premium writings on international pro rata
treaties. This reduction is consistent with the Company's plan of placing an
emphasis on accessing clients directly rather than through pro rata catastrophe
contracts, which have a less efficient cost structure. In addition, the Company
experienced a reduction in its international direct business of approximately
$6.0 million. This related to renewal business which incepted in the first
calendar quarter of 1999 and was renewed primarily on a fifteen month basis to
avoid Year 2000 issues. Most of this premium will now be up for renewal in the
second calendar quarter of 2000.

For the six months ended March 31, 2000, gross premiums written in lines of
business, other than property catastrophe, totaled $8.9 million compared to
$16.9 million for the six months ended March 31, 1999. The decrease is
principally a function of contracts not available for renewal, due to
cancellation or writings on a multi-year basis.

Gross premiums written by LaSalle Re Capital were comparable at $10.1 million
for the six months ended March 31, 2000 and $9.5 million for the six months
ended March 31, 1999.

During the six months ended March 31, 2000, the Company experienced premium
adjustments of $1.9 million compared to $5.3 million for the six months ended
March 31, 1999. These adjustments are primarily due to the revision of premium
estimates on pro rata property catastrophe contracts following the receipt of
updated information from cedents. In addition, the Company recorded an increase
in the level of reinstatement premiums of $4.4 million due to increased loss
activity.

Premiums ceded for the six months ended March 31, 2000 were consistent with the
level in the six months ended March 31, 1999 at $17.6 million and $17.4 million
respectively.

As a result of the above, net premiums written for the six months ended March
31, 2000 were $57.9 million compared to $83.0 million for the six months ended
March 31, 1999.

Net premiums earned for the six months ended March 31, 2000 were $57.6 million
compared to $73.2 million for the same period in 1999. The decrease of $15.6
million or 21.3% was principally caused by two factors: a reduction in gross
premiums written from calendar year 1999 to calendar year 2000 and an increase
in the level of ceded premiums amortized. Ceded premiums amortized were $14.3
million for the six months ended March 31, 2000 compared to $5.2 million for the
six months ended March 31, 1999.

Net investment income increased 4.2% to $17.5 million for the six months ended
March 31, 2000 from $16.8 million for the six months ended March 31, 1999.
Annualized investment income as a percentage of the average market value of
invested assets was 6.0% for the six months ended March 31, 2000 compared to
5.5% for the six months ended March 31, 1999.

Net realized losses on investments were $2.2 million during the six months ended
March 31, 2000, compared to net realized gains of $1.6 million for the six
months ended March 31, 1999. Both the losses and gains, in the six months ended
March 31, 2000 and March 31, 1999, were made pursuant to a policy designed to
protect the total returns on the portfolio.

ended March 31, 2000 and 1999:

Losses and loss expenses incurred represent losses paid and reserves established
in respect of specific losses and loss expenses reported by cedents and expected
loss development and additions to incurred-but-not-reported loss reserves.

The Company incurred net losses and loss expenses of $90.2 million during the
six months ended March 31, 2000 compared with $80.8 million during the six
months ended March 31, 1999. Of the losses incurred for the six months ended
March 31, 2000, a significant portion related to two storms which struck
northwest Europe, including France

and Germany, on December 26 and 27, 1999. The Company has booked expected net
losses of $23.6 million for Storm Lothar and $23.1 million for Storm Martin.
This is based on the Company's estimate of the market loss for the two storms at
$9.0 billion. This magnitude of loss assumes full limit losses on all French
specific contracts and a conservative reserve for non-specific contracts. In
addition, the Company established $12.5 million of loss reserves for a
significant storm that hit Denmark on December 3, 1999. Following notification
from a syndicate supported by LaSalle Re Capital, the Company has recorded $7.4
million for loss reserves. These losses relate to a particular program that was
underwritten by the syndicate in 1997 through to 1999. The loss reserves
recorded by the Company represent the potential full liability for losses from
this program. The remaining $23.6 million principally related to smaller losses
and the establishment of reserves for other events that occurred during the six
months but which have not yet been reported.

During the six months ended March 31, 1999, the Company provided additional
reserves on tornadoes that hit the mid-western states of the United States in
January 1999 and also reserved for other events that occurred during the six
months but had not yet been reported.  These losses and loss reserves amounted
to approximately $30.8 million. In addition to these claims, the Company
strengthened prior year reserves.  Additional loss reserves were established for
Hurricane Georges which occurred in September 1998.  Also, approximately $14
million of additional case reserves for large losses and an additional $20
million of incurred-but-not-reported loss reserves, following a review of the
assumptions used in setting incurred-but-not-reported loss reserves, were
recorded.

The expense ratio includes underwriting expenses and operational expenses.
Underwriting expenses include brokerage, commissions, excise taxes and other
costs related to underwriting reinsurance contracts.

Underwriting expenses as a percentage of net earned premiums were 20.6% for the
six months ended March 31, 2000 compared to 16.4% for the six months ended March
31, 1999. The increase in the ratio of 4.2% was principally due to the increased
amount of amortized ceded reinsurance that reduced net premiums earned. For the
six months ended March 31, 2000 underwriting expenses as a percentage of gross
premiums earned were 16.6% compared to 15.3% for the quarter ended March 31,
1999. This increase was principally due to an increase in the provision accrued
for profit commission with respect to one specific contract.

Operational expenses were $6.8 million for the six months ended March 31, 2000,
compared to $4.8 million for the six months ended March 31, 1999. As a
percentage of net premiums earned, operational expenses were 11.8% during the
six months ended March 31, 2000 and 6.6% for the six months ended March 31,
1999. The increase in operational expenses of $2.0 million was principally due
to an increase in the level of executive compensation booked in connection with
an outstanding grant of stock appreciation rights. During the six months ended
March 31, 1999, the Company recorded a credit of $1.5 million in respect of
these stock appreciation rights, compared with insignificant movement in the six
months ended March 31, 2000.

Corporate expenses were $1.8 million for the six months ended March 31, 2000 and
related primarily to the business combination agreement with Trenwick Group Inc.
For the six months ended March 31, 1999, corporate expenses were $0.3 million
and related to the preparation and filing of a registration statement for an
offering of preferred shares which was subsequently withdrawn prior to becoming
effective.

Interest expense was $0.7 million during the six months ended March 31, 2000
compared with $0.9 million during the six months ended March 31, 1999. Interest
expense included financing charges associated with the deposit portion of
LaSalle Re's ceded reinsurance contract and other interest expenses related to
the ongoing commitment fees payable on the Company's credit facility. As at
March 31, 1999, there were no borrowings under this facility.

The Company's loss per share, both basic and diluted, was $2.05 for the six
months ended March 31, 2000 compared to a loss of $0.51 for the six months ended
March 31, 1999.


Liquidity and Capital Resources

As a holding company, the Company's assets consist primarily of all of the
outstanding voting stock of LaSalle Re.  The Company's cash flows depend
primarily on dividends and other permitted payments from LaSalle Re and its
subsidiaries.

LaSalle Re's sources of funds consist of net premiums written, investment income
and proceeds from sales and redemptions of investments.  Cash is used primarily
to pay losses and loss expenses, brokerage, commissions, excise taxes,
administrative expenses and dividends.  Under the Insurance Act, 1978,
amendments thereto and related regulations of Bermuda (the "Insurance Act"),
LaSalle Re is prohibited from paying dividends of more than 25% of its opening
statutory capital and surplus unless it files an affidavit stating that it will
continue to meet the required solvency margin and minimum liquidity ratio
requirements and from declaring or paying any dividends without the approval of
the Bermuda Minister of Finance if it failed to meet its required margins in the
previous fiscal year.  The Insurance Act also requires LaSalle Re to maintain a
minimum solvency margin and minimum liquidity ratio and prohibits dividends,
which would result in a breach of these requirements.  In addition, LaSalle Re
is prohibited under the Insurance Act from reducing its total opening statutory
capital by more than 15% without the approval of the Minister of Finance.
LaSalle Re currently meets these requirements. The payment of dividends by
LaSalle Re is also subject to the rights of holders of the Exchangeable Non-
Voting Shares to receive a pro rata share of any dividend and to LaSalle Re's
need to maintain shareholders' equity adequate to support the level of its
insurance operations.

Operating activities provided net cash of $27.9 million for the six months ended
March 31, 2000 and $8.0 million for the six months ended March 31, 1999.  Cash
flows from operations in future years may differ substantially from net income.
Cash flows are affected by loss payments, which, due to the nature of the
reinsurance coverage provided by LaSalle Re, are generally expected to comprise
large loss payments on a

limited number of claims and can therefore fluctuate significantly from year to
year. The irregular timing of these large loss payments can create significant
variations in operating cash flows between periods. LaSalle Re funds such
payments from cash flows from operations and sales of investments.

As a result of the potential for large loss payments, LaSalle Re maintains a
substantial portion of its assets in cash and investments.  As of March 31,
2000, 74.2% of its total assets were held in cash and investments.  To further
mitigate the uncertainty surrounding the amount and timing of potential
liabilities and to minimize interest rate risk, LaSalle Re maintains a short
average duration for its investment portfolio.  The modified average duration of
the portfolio was 2.8 years at March 31, 2000.  At March 31, 2000, the fair
value of the Company's total investment portfolio, including cash, was $576.7
million.

At March 31, 2000, 76.8% of the securities held in the Company's investment
portfolio were fixed-income securities rated "AA" or better and 95.9% were
fixed-income securities rated "A" or better by S&P or Moody's. No single
investment comprised more than 5% of the overall portfolio. As at March 31,
2000, issuers from the Far East and Asia represented 1.5% of the investment
portfolio. These securities had a market value of $8.4 million and an aggregate
unrealized loss of $0.1 million. All of these securities had a credit rating of
AAA as assigned by S&P or Moody's, as at March 31, 2000.

The Company has adopted the Statement of Financial Accounting Standard No. 115
("SFAS 115") to account for its marketable securities with all of the Company's
investments classified as "available for sale".  Under this classification,
investments are recorded at fair market value and any unrealized gains or losses
are reported as "Accumulated other comprehensive income", a separate component
of shareholders' equity. In accordance with SFAS No. 130 "Reporting of
Comprehensive Income", the movement in unrealized gains or losses on these
investments are disclosed as part of other comprehensive income. The unrealized
loss on the investment portfolio, net of amounts attributable to minority
interest, was $6.6 million at March 31, 2000 compared to a loss of $4.1 million
at September 30, 1999.

Reinsurance balances receivable were $107.2 million at March 31, 2000 compared
to $93.2 million at September 30, 1999. Included within reinsurance balances
receivable at March 31, 2000 was $54.1 million that related to the business
written by LaSalle Re Capital, compared to $46.0 million as at September 30,
1999. Given the three-year accounting methodology utilized by Lloyd's, these
receivable balances will only start to be received by the Company during the
later part of 2000.

Prepaid reinsurance premiums increased from $17.3 million as at September 30,
1999 to $20.6 million as at March 31, 2000, following continued reinsurance
purchases. At March 31, 2000, the Company had $13.8 million of losses
recoverable from reinsurers compared to $9.1 million at September 30, 1999.

Other assets decreased from $37.6 million as at September 30, 1999 to $33.6
million as at March 31, 2000. This was primarily caused by a reduction in the
value of the asset carried in respect of the multi year reinsurance contract due
to the part receipt of no claims bonuses and reduced coverage for the 2000 year.

--------------------------------------------------------------------------------

At March 31, 2000, reserves for unpaid losses and loss expenses were $212.5
million compared to $146.6 million at September 30, 1999. During the six months
ended March 31, 2000, the Company established significant reserves for the
storms that hit northwest Europe. At March 31, 2000 the Company had recorded
loss reserves of $28.6 million in respect of the business underwritten by
LaSalle Re Capital compared with $18.7 million at September 30, 1999. Given the
three-year accounting methodology, these loss reserves will only start to be
paid by the Company during the later part of 2000.

Other liabilities increased from $37.3 million as at September 30, 1999 to $54.3
million as at March 31, 2000. The increase of $17.0 million was primarily due to
liabilities established for the multi-year excess of loss reinsurance program
and other reinsurance protections.

On March 1, 2000, the Company paid a dividend of $.5469 per share to holders of
record of Series A preferred shares on January 28, 2000.  As of March 31, 2000
dividends due but not yet paid on the Series A preferred shares amounted to $0.5
million.

In accordance with the terms of certain reinsurance contracts, the Company
posted letters of credit in the aggregate amount of $21.5 million as of March
31, 2000 compared to $21.3 million as of September 30, 1999 to support
outstanding loss reserves.  In connection with LaSalle Re Capital's support of
three Lloyd's syndicates, with effect from January 1, 1997 the Company posted
letters of credit in the aggregate amount of $15.6 million (equivalent to
(Pounds)9.8 million). In addition, in connection with a swap agreement, the
Company has posted a letter of credit of $3.0 million.  All letters of credit
are secured by a lien on the Company's investment portfolio equal to 115% of the
amount of the outstanding letters of credit.

The Company has in place a $100 million committed line of credit from a
syndicate of banks.  The proceeds from the credit facility may only be used to
buy preferred shares of LaSalle Re that, in turn, may use the proceeds of such
purchase to meet current cash requirements.  The facility matures December 1,
2000, and is secured by a pledge ("legal mortgage") of all the capital stock of
LaSalle Re held by the Company, including any preferred shares that may be
issued by LaSalle Re to the Company.  The line of credit contains various
covenants, including limitations on incurring additional indebtedness;
restrictions on the sale or lease of assets not in the ordinary course of
business; maintenance of a ratio of consolidated total debt to consolidated
tangible net worth of no more than 0.40 to 1.00; maintenance of tangible net
worth at the end of each fiscal year of the greater of $300 million or 70% of
net premiums written; maintenance of statutory capital of LaSalle Re of at least
$400 million; and maintenance of a ratio of net premiums written to statutory
capital at the end of any fiscal quarter for the four fiscal quarters then ended
of no more than 1.00 to 1.00 in each case.  The Company may pay dividends and
make other restricted payments so long as, after giving effect to such
restricted payments, no event of default has occurred. Dividends and restricted
payments are limited to 50% of consolidated net income for its immediately
preceding fiscal year less amounts paid on the Series A preferred shares.  In
order for the Company to pay dividends in excess of 50% of consolidated net
income, the Company

would have to renegotiate certain terms of its credit facility. As of March 31,
2000, there were no outstanding borrowings under the credit facility.

The Company's financial condition and results of operations are influenced by
both internal and external forces. Loss payments, investment returns and
premiums may be impacted by changing rates of inflation and other economic
conditions. Cash flows from operations and the liquidity of its investment
portfolio are, in the Company's opinion, adequate to meet the Company's expected
cash requirements over the next 12 months.

In June 1998, the Financial Accounting Standards Board issued SFAS No. 133
"Accounting for Derivative Instruments and Hedging Activities".  This statement
is effective for all fiscal quarters of fiscal years beginning after June 15,
2000.  Given the limited number of transactions currently entered into by the
Company that are covered by the Statement, the Company does not anticipate any
significant changes to its current financial reporting.

Quantitative and Qualitative Disclosure about Market Risk

The Company made disclosure relating to its market risks in the Form 10-K for
the year ended September 30, 1999. The Company believes there have been no
material changes with respect to its market risks during the six months ended
March 31, 2000.
