ITEM 1.    BUSINESS

General Description of the Company's Business

         W. R. Berkley Corporation (the "Company"), a Delaware corporation, is
an insurance holding company, which through its subsidiaries, presently operates
in all segments of the property casualty insurance business: regional property
casualty insurance; reinsurance (conducted through Signet Star Holdings, Inc.);
specialty lines of insurance (including excess and surplus lines and commercial
transportation); alternative markets (including the management of alternative
insurance market mechanisms); and international (conducted through Berkley
International, LLC). The Company was founded on the concept that a group of
autonomous regional and specialty insurance entities could compete effectively
in selected markets within a very large industry. Decentralized control allows
each subsidiary to respond to local or specialty market conditions while
capitalizing on the effectiveness of centralized investment and reinsurance
management, and actuarial, financial and legal staff support.

         The Company's regional insurance operations are conducted primarily in
the Midwestern, Southern and Northeastern sections of the United States.
Reinsurance, specialty insurance and alternative markets operations are
conducted nationwide. Presently, international operations are conducted
primarily in Argentina and the Philippines.


         Net premiums written, as reported on a generally accepted accounting
principles ("GAAP") basis, by the Company's five major insurance industry
segments for the five years ended December 31, 1997 were as follows:

treaty and a facultative basis. Signet Star Holdings, Inc. (Signet Star),
through its subsidiary Signet Star Reinsurance Company, includes the results of

For financial segment reporting purposes the results of the alternative market

         The largest business unit in terms of personnel and premiums written,
this division of Signet Star is committed exclusively to the broker market
segment of the treaty reinsurance industry. It functions as a traditional
reinsurer in specialty and standard reinsurance lines.

Facultative ReSources, Inc.

         Facultative ReSources, Inc. ("Fac Re") specializes in individual
certificate and program facultative business. Fac Re's highly experienced
underwriters seek to offset the underwriting and pricing cycles in the
underlying insurance business by developing risk management solutions and
through superior risk selection. Fac Re develops its business through brokers
and on a direct basis where the client does not choose to use an intermediary.

The Fidelity and Surety Division

         The Fidelity and Surety Division ("F&S") operates as a lead reinsurer
in a niche market of the United States property casualty industry where its
highly specialized knowledge and expertise are essential to meet the needs of
Fidelity and Surety primary writers. Business is marketed principally through
brokers as well as directly to clients not served by intermediaries.

The Latin American and Caribbean Division

lines of property and casualty treaty business and is developing a book of niche
business.

Gemini Insurance Company

         Gemini is an excess and surplus lines insurance company created to
provide Signet Star with primary issuing carrier capability and thereby generate

primary business that it then cedes back to itself. Gemini provides Signet Star
with a controlled source of new business. It operates as an authorized insurance
company in the State of Delaware and will operate nationwide, as necessary legal
and regulatory requirements are met, as an approved excess and surplus lines
carrier.

         The Company's specialty lines of insurance consist primarily of excess
and surplus lines ("E & S"), commercial transportation, professional liability,
directors and officers liability and surety. Specialty lines also included the
results of the Company's reinsurance operations through June 30, 1993 (see:
"Other information about the Company's business").

Admiral Insurance Company

         The majority of the Company's E & S insurance business is conducted by
Admiral Insurance Company ("Admiral"). Admiral specializes in general liability
coverages, including products liability and professional liability. Admiral
insures risks requiring specialized treatment not available in the conventional
market, with coverage designed to meet the specific needs of the insured.
Business is received from wholesale brokers via retail agents, whose clients are
the insureds. E & S carriers operate on a non-admitted basis in the states where
they write business. They are generally free from rate regulation and policy
form requirements. Admiral's business is obtained on a nationwide basis from
approximately 190 non-exclusive brokers, who do not have the authority to commit
the Company, and who are compensated on a commission basis. Admiral also writes
directors and officers liability insurance through operations conducted by
Monitor Liability Managers, Inc., an underwriting manager established by the
Company. Admiral is rated A++ by A.M. Best. Admiral's statutory surplus and
statutory net premiums written as of December 31, 1997 and for the year then
ended were $218,917,000 and $72,103,000, respectively.

Carolina Casualty Insurance Company

         The Company's commercial transportation operations are primarily
conducted by Carolina Casualty Insurance Company ("Carolina"). Carolina writes
liability, physical damage and cargo insurance for the transportation industry,
concentrating on long-haul trucking companies. Municipal bus lines, charter
buses and school buses also make up a substantial part of Carolina's book of
business. Carolina's business is obtained nationwide from approximately 120
agents and brokers who are compensated on a commission basis. In June 1995,
Carolina began writing surety bonds through operations conducted by Monitor
Surety Managers, Inc., an

Carolina's statutory surplus and statutory net premiums written as of December
31, 1997 and for the year then ended were $66,004,000 and $50,550,000,
respectively.

Nautilus Insurance Company

         Nautilus Insurance Company ("Nautilus") was established in 1985 to
insure E & S risks which involve a lower degree of expected severity than those
covered by Admiral. Nautilus obtains its business nationwide from approximately
135 non-exclusive general agents, some of which also provide business to
Admiral. A substantial portion of Nautilus' business is written on a binding
authority basis, subject to certain contractual limitations. Nautilus is rated A
by A.M. Best. Nautilus's statutory surplus and statutory net premiums written as
of December 31, 1997 and for the year then ended were $68,092,000 at
$45,494,000, respectively. Great Divide Insurance Company ("Great Divide"), a

lines, on an admitted basis.

Loss and Loss Adjustment Expense Reserves

         In the property casualty industry, it is not unusual for significant
periods of time, ranging up to several years or more, to elapse between the
occurrence of an insured loss, the report of the loss to the insurer and the
insurer's payment of that loss. To recognize liabilities for unpaid losses,
insurers establish reserves, which is a balance sheet account representing
estimates of future amounts needed to pay claims and related expenses with
respect to insured events which have occurred. The Company's loss reserves
reflect current estimates of the ultimate cost of closing outstanding claims;
other than its Excess Workers Compensation business, as discussed below, the
Company does not discount its reserves to estimated present value for financial
reporting purposes.

         In general, when a claim is reported, claims personnel establish a
"case reserve" for the estimated amount of the ultimate payment. The estimate
represents an informed judgment based on general reserving practices and
reflects the experience and knowledge of the claims personnel regarding the
nature and value of the specific type of claim. Reserves are also established on
an aggregate basis which provide for losses incurred but not yet reported to the
insurer, potential inadequacy of case reserves, the estimated expenses of
settling claims, including legal and other fees and general expenses of
administering the claims adjustment process ("LAE"), and a provision for
potentially uncollectible reinsurance. Each insurance subsidiary's net retention
for each line of insurance is taken into consideration in the computation of
ultimate losses.

         In examining reserve adequacy, historical data is reviewed and
consideration is given to such factors as legal developments, changes in social
attitudes and economic conditions, including the effects of inflation. The
actuarial process relies on the basic assumption that


                                       14
   15
past experience, judgmentally adjusted for the effects of current developments
and anticipated trends, is an appropriate basis for predicting future events.
Reserve amounts are necessarily based on management's informed estimates and
judgments using data currently available. As additional experience and other
data become available and are reviewed, these estimates and judgments are
revised, resulting in increases or decreases to reserves for insured events of
prior years. The reserving process implicitly recognizes the impact of inflation
and other factors affecting loss costs by taking into account changes in
historic claim patterns and perceived trends. There is no precise method to
evaluate the impact of any specific factor on the adequacy of reserves, because
the ultimate cost of closing claims is influenced by numerous factors.

         While the methods for establishing the reserves are well tested over
time, some of the major assumptions about anticipated loss emergence patterns
are subject to fluctuation. In particular, high levels of jury verdicts against
insurers, as well as judicial decisions which "re-formulate" policies to expand
their coverage to previously unforeseen theories of liability, including those
regarding pollution and other environmental exposures, have produced
unanticipated claims and increased the difficulty of estimating the loss and
loss adjustment expense reserves provided by the Company. With respect to year
2000 claims exposure for our insurance and reinsurance subsidiaries, to date,
no significant losses have arisen. However, due to the potential judicial
decisions which re-formulate policies to expand their coverage to previously
unforeseen theories of liabilities which may produce unanticipated claims, at
this point in time, the estimation of any potential year 2000 liabilities is
not determinable.


         Due to the nature of EWC business and the long period of time over
which losses are paid in this line of business, the Company discounts its
liabilities for EWC losses and loss expenses. Discounting liabilities for losses
and loss expenses gives recognition to the time value of money set aside to pay
claims in the future and is intended to appropriately match losses and loss
expenses to income earned on investment securities supporting the liabilities.
The expected losses and loss expense payout pattern subject to discounting was
derived from Midwest's loss payout experience and is supplemented with data
compiled by insurance companies writing workers' compensation on an
excess-of-loss basis. The expected payout pattern has a very long duration
because it reflects the nature of losses which generally penetrate self-insured
retention limits contained in EWC policies. The Company has limited the expected
payout duration to 30 years in order to introduce an additional level of
conservatism into the discounting process. These liabilities have been
discounted using "risk-free" discount rates determined by reference to the U.S.
Treasury yield curve weighted for EWC premium volume to reflect the seasonality
of the anticipated duration of losses associated with such coverages. The
average discount rate for accident years 1997, 1996 and 1995 and prior was
approximately 5.98%, 5.90% and 5.80%, respectively. The aggregate net discount,
after reflecting the effects of ceded reinsurance, is $189,600,000, $172,415,000
and $152,235,000 at December 31, 1997, 1996 and 1995, respectively.

         To date, known pollution and environmental claims at the Company's
insurance company subsidiaries have not had a material impact on the Company's
operations. Environmental claims have not materially impacted the Company
because these subsidiaries generally did not insure the larger industrial
companies which are subject to significant environmental exposures.

         The Company's net reserves for losses and loss adjustment expenses
relating to pollution and environmental claims were $33.1 million and $35.2
million at December 31, 1997 and 1996, respectively. The Company's gross
reserves for losses and loss adjustment expenses relating to pollution and
environmental claims were $68.4 million and $71.9 million at December 31, 1997
and 1996, respectively. Net incurred losses and loss expenses for reported
pollution and environmental claims were approximately $0.1 million, $6.9 million
and $8.0 million in 1997, 1996 and 1995, respectively. Net paid losses and loss
expenses has averaged approximately $3 million for each of the last three years.
The estimation of these liabilities is subject to significantly greater than
normal variation and uncertainty because it is difficult to make a reasonable
actuarial estimate of these liabilities due to the absence of a generally
accepted actuarial methodology for these exposures and the potential affect of
significant unresolved legal matters, including coverage issues as well as the
cost of litigating the legal issues. Additionally, the determination of ultimate
damages and the final allocation of such damages to financially responsible
parties is highly uncertain.

(1)      Claims occurring during the current year is net of discount of
         $29,783,000, 28,885,000 and $708,000 for the years ended December 31,
         1997, 1996 and 1995, respectively.

(2)      For statutory purposes, Midwest uses a discount rate of 3.0% as
         permitted by the Department of Insurance of the State of Ohio. For GAAP
         purposes, Midwest uses a discount rate based on the U. S. Treasury
         yield curve weighted for the expected payout period, as described
         above.

         The following table presents the development of net reserves for 1986
through 1997. The top line of the table shows the estimated reserves for unpaid
losses and loss expenses recorded at the balance sheet date for each of the
indicated years. This represents the estimated amount of losses and loss
expenses for claims arising in all prior years that are unpaid at the balance
sheet date, including losses that had been incurred but not yet reported to the
Company. The upper portion of the table shows the re-estimated amount of the
previously recorded reserves based on experience as of the end of each
succeeding year. The estimate changes as more information becomes known about
the frequency and severity of claims for individual years.

         The "cumulative redundancy (deficiency)" represents the aggregate
change in the estimates over all prior years. For example, the 1986 reserves
have developed a $47 million deficiency over ten years. That amount has been
reflected in income over the ten years. The impact on the results of operations
of the past three years of changes in reserve estimates is shown in the
reconciliation tables above.

         It should be noted that the table presents a "run off" of balance sheet
reserves, rather than accident or policy year loss development. Therefore, each
amount in the table includes the effects of changes in reserves for all prior
years. For example, assume a claim that occurred in 1987 is reserved for $2,000
as of December 31, 1987. Assuming this claim was settled for $2,300 in 1997, the
$300 deficiency would appear as a deficiency in each year from 1987 through
1996.

Regulation

         The Company's insurance subsidiaries are subject to varying degrees of
regulation and supervision in the jurisdictions in which they do business, under
statutes which delegate regulatory, supervisory and administrative powers to
state insurance commissioners. This regulation relates to such matters as the
standards of solvency which must be met and maintained; the licensing of
insurers and their agents; the nature of and limitations on investments;
deposits of securities for the benefit of policyholders; approval of policy
forms and premium rates; periodic examination of the affairs of insurance
companies; annual and other reports required to be filed on the financial
condition of insurers or for other purposes; establishment and maintenance of
reserves for unearned premiums and losses; and requirements regarding numerous
other matters. In general, the Company's regional property casualty subsidiaries
as well as Carolina, Great Divide and Midwest must file all rates for personal
and commercial insurance with the insurance department of each state in which
they operate. The Company's E&S and reinsurance subsidiaries generally operate
free of rate and form regulation.

         In addition to regulatory supervision of its insurance subsidiaries,
the Company is subject to state statutes governing insurance holding company
systems. Typically, such statutes require the Company periodically to file
information with the state insurance commissioner, including information
concerning its capital structure, ownership, financial condition and general
business operations. Under the terms of applicable state statutes, any person or
entity desiring to purchase more than a specified percentage (commonly 10%) of
the Company's outstanding voting securities would be required to obtain
regulatory approval of the purchase. Under Florida law, which is applicable to
the Company due to its ownership of Carolina, a Florida domiciled insurer, the
acquisition of more than 5% of the Company's capital stock must receive
regulatory approval. Further, state insurance statutes typically place
limitations on the amount of dividends or other distributions payable by
insurance companies in order to protect their solvency. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations -
Liquidity and Capital Resources."

         During the past several years, various regulatory and legislative
bodies adopted or proposed new laws or regulations to deal with the cyclical
nature of the insurance industry, catastrophic events and their effects on
shortage of capacity and pricing. These regulations, which have not had a
material impact on the Company's operations, include (i) the creation of "market
assistance plans" under which insurers are induced to provide certain coverages,
(ii) restrictions on the ability of insurers to cancel certain policies in
mid-term, (iii) advance notice requirements or limitations imposed for certain
policy non-renewals and (iv) limitations upon or decreases in rates permitted to
be charged. The passage of Proposition 103 in the State of California did not
have a material adverse impact on the Company's operations because the Company's
subsidiaries operate in that State primarily on a non-admitted basis. The
non-admitted market in California, however, has been subjected to increased
levels of regulation. Admiral and Nautilus, both of which derive significant
premiums from California, may be adversely impacted by increased regulation
which causes business to remain in the admitted market.

         Various state and federal organizations, including Congressional
committees and the National Association of Insurance Commissioners ("NAIC"),
have been conducting investigations into various aspects of the insurance
business. The NAIC has adopted risk based capital ("RBC") requirements that
require insurance companies to calculate and report information under a
risk-based formula which measures statutory capital and surplus needs based on a
regulatory definition of risk in a company's mix of products and its balance
sheet. The implementation of RBC did not effect the operations of the Company's
insurance subsidiaries since all of its subsidiaries have an RBC amount above
the authorized control level RBC, as defined by the NAIC. Federal legislation is
being considered which would either abolish or limit the current exemption of
the insurance industry from portions of the antitrust laws, impose direct
federal oversight or federal solvency standards. No assurance can be given that
future legislative or regulatory changes resulting from such activity will not
adversely affect the Company's insurance subsidiaries.

         The Company's insurance subsidiaries are also subject to assessment by
state guaranty funds when an insurer in that jurisdiction has been judicially
declared insolvent and insufficient funds are available from the liquidated
company to pay policyholders and claimants. The protection afforded under a
state's guaranty fund to policyholders of the insolvent insurer varies from
state to state. Generally, all licensed property casualty insurers are
considered to be members of the fund, and assessments are based upon their pro
rata share of direct written premiums. The NAIC Model Post-Assessment Guaranty
Fund Act, which many states have adopted, limits assessments to an insurer to 2%
of its subject premium and permits recoupment of assessments through rate
setting. Likewise, several states (or underwriting organizations of which the
Company's insurance subsidiaries are required to be members) have limited
assessment authority with regard to deficits in certain lines of business. To
date, assessments have not had a material adverse impact on operations.

         The Company receives funds from its insurance subsidiaries in the form
of dividends and fees for certain management services. Annual dividends in
excess of maximum amounts prescribed by state statutes ("extraordinary
dividends") may not be paid without the approval of the insurance commissioner
of the state in which an insurance subsidiary is domiciled. The NAIC has
proposed and certain states have adopted legislation that lowers the threshold
amount for determining what constitutes an extraordinary dividend. Such
legislative changes could make it more difficult for insurance subsidiaries to
pay dividends to their parents. Similarly, the NAIC has proposed a new model
investment law that may affect the statutory carrying values of certain
investments; however, the final outcome of that proposal is not certain, nor is
it possible to predict what impact the proposal will have on the Company or
whether the proposal will be adopted in the foreseeable future.

Tax Law Changes

         There were no tax law changes in 1997 that significantly affected the
Company.

Competition

         The property casualty insurance and reinsurance business is
competitive, with over 2,000 insurance companies transacting business in the
United States. The Company competes directly with a large number of these
companies. The Company's strategy in this highly fragmented industry is to seek
specialized areas or geographic regions where its insurance subsidiaries can
gain a competitive advantage by responding quickly to changing market
conditions. Each of the Company's subsidiaries establishes its own pricing
practices. Such practices are based upon a Company-wide philosophy to price
products with the general intent of making an underwriting profit. Competition
in the industry generally changes with profitability.

         The regional property casualty subsidiaries compete with mutual and
other regional stock companies as well as national carriers. Direct writers of
property casualty insurance compete with the regional subsidiaries by writing
insurance through their salaried employees, generally at a lower cost than
through independent agents such as those used by the Company.

         Signet Star's competition comes from domestic and foreign reinsurers,
some of which have greater financial resources than Signet Star who place their
business either on a direct basis or through the broker market.

         The E & S area is a highly specialized segment of the insurance
industry. Admiral and Nautilus compete with other E & S carriers, some of which
are larger and have greater resources than Admiral and Nautilus. Under certain
market conditions, standard carriers may compete for the types of business
written by Admiral and Nautilus. In addition, there are regional and specialty
carriers competing with Admiral and Nautilus when they underwrite business in
their regions or specialties.

         Carolina and Great Divide's competition comes mainly from other
specialty transportation insurers and large national multi-line companies.

         Midwest's competition comes from insurance and reinsurance companies,
some of which have greater financial resource than Midwest. Most of theses
carriers write specific EWC


                                       19
   20
coverage, do not offer aggregate EWC coverage and tend to focus on risks larger
than those targeted by Midwest. In addition, Midwest competes with other
specialty EWC insurers.

         The Insurance Services Operations face competition from several large
nationally known service organizations as well as local competitors. The
International Operations compete with native insurance operations both large and
small, which maybe related to government entities, as well as with branch or
local subsidiaries of multi-national companies.

Employees

         As of March 2, 1998, the Company employed 4,046 persons. Of this
number, the Company's subsidiaries employed 3,999 persons, of whom 2,283 were
executive and administrative personnel and 1,716 were clerical personnel. The
Company employed the remaining 47 persons in its parent company and investment
operations, of whom 38 were executive and administrative personnel and 9 were
clerical personnel.

Other information about the Company's business:

         The Company maintains an ongoing interest in acquiring additional
companies and developing new insurance entities, products and packages as
opportunities arise. In addition, the insurance subsidiaries develop new
coverages or lines of business to meet the needs of insureds.

         Seasonal weather variations affect the severity and frequency of losses
sustained by the insurance and reinsurance subsidiaries. Although the effect on
the Company's business of such natural catastrophes as tornadoes, hurricanes,
hailstorms and earthquakes is mitigated by reinsurance, they nevertheless can
have a significant impact on the results of any one reporting period.

         The Company has no customer which accounts for 10 percent or more of
its consolidated revenues.

         Compliance by the Company and its subsidiaries with federal, state and
local provisions which have been enacted or adopted regulating the discharge of
materials into the environment, or otherwise relating to protection of the
environment, has not had a material effect upon the capital expenditures,
earnings or competitive position of the Company.

         The Company currently does not engage in material operations in foreign
countries nor is a material portion of its revenues presently derived from
customers in foreign countries. In 1995, the Company entered into a joint
venture to acquire insurance and insurance related operations outside the United
States (see "International Operations"). However, the Company's insurance
subsidiaries regularly purchase a portion of their catastrophe reinsurance
coverage from foreign reinsurers, including syndicate members of Lloyd's of
London. While Queen's Island is domiciled in Bermuda, to date its business has
exclusively been reinsurance of its domestic affiliates.

         On July 1, 1993, the Company exchanged all the stock of Signet
Reinsurance Company ("Signet") for 60% of the stock of Signet Star, a newly
formed holding company. Signet Star simultaneously acquired all the stock of
North Star Reinsurance Company ("North Star Reinsurance") from General Re in
exchange for 40% of the stock of Signet Star and senior and convertible notes.
In connection with the formation of Signet Star, North Star Reinsurance entered
into a Retrocessional Agreement (the "Retrocessional Agreement") with General
Reinsurance Corporation ("GRC"), pursuant to which North Star Reinsurance
reinsured its respective liabilities and assigned its respective rights and
obligations arising from any insurance or reinsurance contracts written prior to
January 1, 1993 with and to GRC.

         On December 31, 1995, the Company purchased General Re's interest in
Signet Star by issuing to General Re 458,667 shares of Series B Cumulative
Redeemable Preferred Stock of the Company having an aggregate liquidation
preference of $68,800,000, which was redeemed in 1997. In addition, the Company
guaranteed a senior subordinated promissory note of Signet Star which was issued
to General Re in exchange for the convertible note which General Re held. As
part


                                       20
   21
of this transaction, Signet Star sold to General Re Signet Star Reinsurance
Company and renamed Signet Reinsurance Company, Signet Star Reinsurance Company.

         In connection with the 1995 acquisition of the remaining 40% interest
in Signet Star, North Star Reinsurance was sold to General Re and all business
written subsequent to July 1, 1993 was novated to Signet Star. As a result,
business written by North Star Reinsurance prior to January 1, 1993, which had
been retroceded to General Re, is no longer reflected in the Company's financial
statements. The only effect on the Company's financial statements resulting from
this aspect of the transaction is that the Company's reserves for losses and
loss expenses is reduced by $735,144,000 and "due from reinsurers" is reduced by
the same amount. This aspect of the transaction does not effect the Company's
cash flow, equity or statements of operations.

ITEM 2. PROPERTIES

         The Company and its subsidiaries own or lease office buildings or
office space suitable to conduct their operations. Such owned property is as

         In addition, the Company and its subsidiaries lease office facilities
in various other cities under leases with varying terms and expiration dates.

ITEM 3. LEGAL PROCEEDINGS

         Claims under insurance policies written by the Company's insurance
subsidiaries are investigated and settled either by claims adjusters employed by
them, by their independent agents or by independent adjusters. Each subsidiary
employs a staff of claims adjusters at its home office and at some regional
offices. Some independent agents may have the authority to settle small claims.
Independent claims adjusting firms are used to assist in handling various claims
in areas where insurance volume does not warrant the maintenance of a staff
adjuster. If a claim or loss cannot be settled and results in litigation, the
subsidiary generally retains outside counsel.

         At present, neither the Company nor any of its subsidiaries is engaged
in any litigation known to the Company which is expected to have a material
adverse effect upon the Company's business. As is common with property casualty
insurance companies, the Company's subsidiaries are regularly engaged in the
defense of claims arising out of the conduct of the insurance business.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         No matters were submitted during the fourth quarter of 1997 to a vote

             Note to Condensed Financial Statements (Parent Company)


         The accompanying condensed financial statements should be read in
conjunction with the notes to consolidated financial statements included
elsewhere herein. Reclassifications have been made in the 1996 and 1995
financial statements as originally reported to conform them to the presentation
of the 1997 financial statements.

         The Company files a consolidated federal tax return with the results of
its domestic insurance subsidiaries included on a statutory basis. Under present
Company policy, Federal income taxes payable by (or refundable to) subsidiary
companies on a separate-return basis are paid to (or refunded by) W. R. Berkley
Corporation, and the Company pays the tax due on a consolidated return basis.

         Included in fixed maturities available for sale and invested cash is
$113,207,000 and 3,221,000, respectively, of securities placed in a trust which
will be used to service the remaining outstanding shares of the Series A
Preferred Stock. The Company expects that the proceeds of the trust will be
utilized to redeem the Series A Preferred Stock.
