Item 2. Acquisition or Disposition of Assets.

On January 6, 2000 (the "KT Closing Date"), pursuant to the terms
of an Agreement and Plan of Merger (the "Merger Agreement"), dated as of
the 17th day of November, 1999, as amended, by and among KT Holding
Company, a Delaware corporation ("Parent"), KT Acquisition I Corp., a
Delaware corporation ("SubKT"), AH Acquisition I L.L.C., a Delaware limited
liability company ("SubAH"), Knight/Trimark Group, Inc., a Delaware
corporation ("KT"), Arbitrade Holdings LLC, a Delaware limited liability
company ("AH") and Tarmachan Capital Management, Inc., Tarmachan Capital
Co., Deephaven Inc., Gildor Trading, Inc., Irvin Kessler, Efraim Gildor,
Peter Hajas, Merrill Ferguson and Mark Lyons (together, the "Members"), KT
reorganized into a holding company structure as further described below.
Separately, on January 12, 2000 (the "AH Closing Date"), pursuant to the
terms of the Merger Agreement, Parent acquired from the Members all of the
outstanding Class B membership interests of AH (the "AH Membership
Interests").

AH is a technologically advanced options market maker and asset
manager, with operations in the U.S. and Europe.

Parent, a newly formed holding company (which was originally
named KT Holding Company but upon completion of the transactions assumed
the name Knight/Trimark Group, Inc. while KT assumed the name
Knight/Trimark, Inc.), formed two Delaware merger subsidiaries to undertake
two separate transactions. One of such subsidiaries, SubKT, was merged
with and into KT on the KT Closing Date (the "KT Merger"), while the
second, SubAH, was merged with and into AH on the AH Closing Date (the "AH
Merger"), with the result that each of KT and AH became wholly owned
subsidiaries of Parent.

The KT Merger was undertaken in the form of a holding company
reorganization pursuant to the terms of Section 251(g) of the Delaware
General Corporation Law. Such a reorganization did not require stockholder
approval and resulted in the automatic exchange of shares of Class A Common
Stock, par value $.01 per share, of KT for shares of Class A Common Stock,
par value $.01 per share, of Parent, on a one-for-one basis. Following the
closing of the KT Merger, the directors and officers of KT immediately
prior to such closing hold the same offices with Parent. As a result of
the KT Merger, KT is no longer a public company (but is rather a wholly
owned subsidiary of Parent) and Parent replaced KT as the NASDAQ-listed
publicly-owned company.

In accordance with Delaware law, certificates that previously
represented shares of Class A Common Stock of KT are automatically and
without exchange deemed to represent shares of Class A Common Stock of
Parent. The Class A Common Stock of Parent is listed on the Nasdaq
National Market under the symbol "NITE".

Pursuant to the terms of Rule 12g-3(a) under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), the Class A Common
Stock, par value $.01 per share, of Parent, as successor issuer to KT,
shall be deemed registered under Section 12(g) of the Exchange Act.

Separately, the AH Merger resulted in AH becoming a wholly owned
subsidiary of Parent. The Members received 10,505,001 shares of newly-
issued Class A Common Stock of Parent in exchange for all outstanding Class
B membership interests in AH, such shares of Class A Common Stock
representing approximately 8.6% of the outstanding stock of Parent. The
number of shares received by the Members was calculated based on an
exchange ratio which was determined through arms-length negotiation.

The foregoing description of the Merger Agreement contained in
this Form 8-K is a brief summary of the provisions thereof but does not
purport to be complete. This summary is qualified in its entirety by
reference to the Merger Agreement, a copy of which is attached hereto as an
exhibit and incorporated herein by reference.

Item 7(a). Consolidated Financial Statements of Business Acquired

Report of Independent Auditors

The Members
Arbitrade Holdings LLC

We have audited the accompanying consolidated statements of financial
condition of Arbitrade Holdings LLC and subsidiaries as of September 30,
1999 and December 31, 1998, and the related consolidated statements of
operations, members' equity and cash flows for the nine months ended
September 30, 1999 and the years ended December 31, 1998 and 1997. These
financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements
based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by management as well as evaluating the
overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Arbitrade
Holdings LLC and subsidiaries at September 30, 1999 and December 31, 1998,
and the consolidated results of their operations and their cash flows for
the nine months ended September 30, 1999 and the years ended December 31,
1998 and 1997, in conformity with generally accepted accounting principles.

Arbitrade Holdings LLC and Subsidiaries

Notes to Consolidated Financial Statements

1. Organization and Basis of Presentation

Arbitrade Holdings LLC ("Holdings"), a holding company formed on January 1,
1998, is a Delaware limited liability company whose principal wholly-owned
subsidiaries include Arbitrade, L.L.C. (formerly "NU Twins LLC"),
Laboratory for Computerized Trading LLC ("LCT"), Arbitrade U.K. Ltd.,
Deephaven Capital Management LLC, Deephaven Capital LLC and Deephaven
Investment Advisers LLC. Arbitrade, L.L.C. operates as a market maker in
options and trader in equities, debt instruments and related exchange-
traded derivatives. Arbitrade, L.L.C. is a registered broker-dealer with
the Securities and Exchange Commission. Arbitrade U.K. Ltd. is a market
maker in options and trader in equities and exchange-traded derivatives,
trading on most major exchanges in Europe. LCT provides the technology
support and development for Arbitrade, L.L.C., Arbitrade U.K. Ltd., and the
Company's asset management business. Deephaven Capital Management LLC,
Deephaven Capital LLC and Deephaven Investment Advisers LLC operate as
investment managers and sponsors for a series of limited partnerships,
offshore corporations and limited liability companies.

As of January 1, 1998, the LLC interests of Arbitrade, L.L.C. and LCT were
exchanged for LLC interests in Holdings. In addition, Deephaven Capital
Management LLC and Deephaven Capital LLC were formed as operating
subsidiaries of Holdings to continue the business previously done through
Tarmachan Capital Management and Tarmachan Capital Co. (collectively, the
"Tarmachan S corporations"), respectively. The assets and liabilities of
the Tarmachan S corporations as of January 1, 1998, including the
agreements to manage the assets of the private investment funds which had a
carrying value of zero, were exchanged for LLC interests in Holdings. All
assets and liabilities contributed in the formation of Holdings retained
their then current carrying values due to the common ownership of the
businesses before and after the formation of Holdings.

Arbitrade U.K. Ltd. began trading operations on February 1, 1998 to carry
on the business previously done by Kessler Asher Derivatives Gmbh ("Gmbh").
As of January 1, 1998, Gmbh and its parent, Kessler Asher International
L.P., were wholly owned by Holdings. The net assets of Gmbh and Kessler
Asher International L.P. as of February 1, 1998 were transferred to
Arbitrade U.K. Ltd. as a capital contribution from Holdings. After the
transfer, Gmbh and Kessler Asher International L.P. were liquidated.

As of February 1, 1998, Deephaven Investment Advisers LLC was formed to
serve as the investment manager and sponsor for a new group of private
investment funds.

The consolidated financial statements as of and for the nine months ended
September 30, 1999 and the year ended December 31, 1998 include the
accounts of Holdings and its wholly-owned subsidiaries (collectively, "the
Company"). The combined financial statements for the year ended December
31, 1997 consist of the following predecessor companies of the Company, all
under common control: NU Twins LLC, LCT, Tarmachan S corporations and Gmbh.
The financial statements for all periods presented are presented in U.S.
dollars. All significant intercompany balances and transactions have been
eliminated. Certain items presented in prior year financial statements have
been reclassified to conform with current year presentation.

2. Summary of Significant Accounting Policies

USE OF ESTIMATES

Generally accepted accounting principles require management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosures of contingent assets and liabilities at the
date of the consolidated financial statements and the reported amounts of
revenues and expenses during the reporting periods. Actual results could
differ from those estimates.

SECURITIES OWNED AND SECURITIES SOLD, NOT YET PURCHASED

Securities owned and securities sold, not yet purchased are valued at
market value based on quoted market prices. Unrealized gains and losses are
reflected in principal transactions in the consolidated statements of
operations. Securities sold, not yet purchased represent obligations of the
Company to purchase the securities at prevailing market prices. The
ultimate gains or losses realized are dependent upon the prices at which
these securities are purchased to settle the obligation under the sales
commitments. Securities transactions are recorded on the trade date.
Receivables and payables relating to trades pending settlement are included
in receivables from clearing brokers and payables to clearing brokers in
the consolidated statements of financial condition.

INVESTMENTS IN PRIVATE INVESTMENT FUNDS

Investments in a series of limited partnerships, offshore corporations and
limited liability companies (collectively, "private investment funds") are
accounted for using the equity method, under which the Company's share of
net income or loss is reflected in income as earned and distributions
received, if any, are reductions of the investments.

OTHER INVESTMENTS

Other investments consist primarily of securities offered in private
placements. These securities are valued as estimated in good faith by
management in the absence of readily ascertainable market values. In
valuing the investments, management takes into consideration factors such
as the length of time since the investment was made, the financial
condition and operating results of the issuer, recent sales prices of the
issuer's securities, and the proportion of the issuer's securities owned.
Because of the inherent uncertainty of valuation, those estimated values
may differ significantly from the values that would have been used had a
ready market for the investments existed.

FUTURES TRANSACTIONS

Futures and options on futures contracts are valued at market value based
on exchange settlement prices. Unrealized gains and losses on futures and
options on futures contracts are reflected in net trading revenue in the
consolidated statements of operations.

RESALE AND REPURCHASE AGREEMENTS

Securities purchased under agreements to resell ("resale agreements") and
securities sold under agreements to repurchase ("repurchase agreements")
are accounted for as collateralized financing transactions and are recorded
at their contracted resale or repurchase amounts plus accrued interest.
Counterparties are major financial institutions. The Company's policy is to
take possession or control of securities with a market value in excess of
the principal amount loaned, plus accrued interest, in order to
collateralize securities purchased under agreements to resell. The Company
monitors the market value of the underlying securities which collateralize
the related receivable on resale agreements, including accrued interest,
and requests additional collateral when deemed appropriate. Similarly, the
Company is required to provide securities to counterparties in order to
collateralize securities sold under agreements to repurchase.

PROPERTY, LEASEHOLD IMPROVEMENTS AND EQUIPMENT

Property, leasehold improvements and equipment are recorded at cost.
Property and equipment is depreciated over their estimated useful lives
using the straight-line method. Leasehold improvements are amortized over
the respective lease term using the straight-line method. At September 30,
1999 and December 31, 1998, accumulated depreciation totaled $3,453,383 and
$2,125,486, respectively.

INTANGIBLES

Intangibles are being amortized on a straight-line basis over 15 years.

FOREIGN CURRENCIES

Assets and liabilities in foreign currencies are translated into U.S.
dollars using current exchange rates at the date of the consolidated
statements of financial condition. Revenues and expenses are translated at
average rates during the periods. The functional currency of the Company's
wholly-owned foreign subsidiary is the U.S. dollar. The foreign exchange
gains and losses resulting from these transactions are included in other
operating expenses in the consolidated statements of operations.

INCOME TAXES

No provision has been made for U.S. federal and state income taxes as the
taxable income or loss of the Company is included in the respective income
tax returns of the members. A provision has been made for applicable
foreign income taxes.

FAIR VALUE OF FINANCIAL INSTRUMENTS

All of the Company's financial instruments are carried at fair value or
amounts approximating fair value.

COMPREHENSIVE INCOME

The Company has adopted Statement of Financial Accounting Standards
("SFAS")
No. 130, Reporting Comprehensive Income, that requires companies to report
all changes in equity during a period, except those resulting from
investments by owners and distributions to owners. The Company has not
presented a consolidated statement of comprehensive income because it does
not have any items of "other comprehensive income."

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1997, the Financial Accounting Standards Board (FASB) issued SFAS
No. 131, Disclosures about Segments of an Enterprise and Related
Information, effective for fiscal years beginning after December 15, 1997.
SFAS No. 131 requires the disclosure of financial and descriptive
information about reportable operating segments. Operating segments are
components of an enterprise about which financial information is available
and is evaluated regularly in deciding how to allocate resources and assess
performance. SFAS No. 131 also requires the disclosure of profit or loss,
certain specific revenue and expense items, and assets of all operating
segments, with reconciliations of amounts presented in the financial
statements. SFAS No. 131 also requires the disclosure of how the operating
segments were determined, the products and services provided by the
segments, differences between measurements used in reporting segment
information and those used in the financial statements, and changes in the
measurement of segment amounts from period to period. The Company adopted
SFAS No. 131 in 1998.

In March 1998, the American Institute of Certified Public Accountants (the
"AICPA") issued Statement of Position 98-1, Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use ("SOP 98-1"). This
statement requires that certain costs of computer software developed or
obtained for internal use be capitalized and amortized over the useful life
of the related software. SOP 98-1 is effective for financial statements for
fiscal years beginning after December 15, 1998. The Company adopted SOP 98-
1 as of January 1, 1999. Prior to the Company's adoption of SOP 98-1, the
Company expensed its costs of developing computer software and capitalized
the costs of computer software acquired from third parties. The effect of
adopting SOP 98-1 was to increase net income for the nine months ended
September 30, 1999 by $1,461,000.

In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. The new rules establish standards
requiring that all derivative financial instruments be recognized and
measured at fair value regardless of the purpose or intent for holding
them. SFAS No. 133 also reduces certain previously required quantitative
disclosures relating to derivative financial instruments held or issued for
trading purposes. The Company adopted SFAS No. 133 in 1998 and the adoption
did not have a significant impact on the Company's consolidated financial
statements.

under which it borrows on a revolving basis. The borrowing is
collateralized with substantially all assets of the Company. Interest is
variable based on prime plus one percent per annum and payable monthly. The
Company pays a one half percent per annum commitment fee on the unused
portion of the facility. The unused portion of the facility and interest
rate at September 30, 1999 were $2,732,172 and 9.25%, respectively, and

Deephaven Capital Management LLC, Deephaven Capital LLC and
Deephaven Investment Advisers LLC are the investment managers and sponsors
of private investment funds that engage in various trading strategies
involving equities, debt instruments and derivatives. The Company owns
interests in these private investment funds. Several members of Holdings
also own interests in these private investment funds. Summary financial
information for these private investment funds at September 30, 1999 and
December 31, 1998, and for the nine and twelve months then ended,
respectively, was as follows:

1999 1998
---------------------------------

Total assets $1,562,814,952 $1,490,887,848
Total liabilities 1,214,703,275 1,162,742,176

The Company's pro rata share of net income from the above private
investment funds for the year ended December 31, 1997 was $364,147. These
amounts are included in other income in the consolidated statements of
operations.

The Company earns income from these private investment funds consisting of
management and incentive fees, as provided for in each respective
investment fund agreement. The Company earned fees of $14,909,013 for the
nine months ended September 30, 1999, $6,134,265, for the year ended
December 31, 1998 and $7,389,188 for the year ended December 31, 1997.

6. Acquisition of Specialist Operations

Effective July 21, 1999, the Company acquired the partnership interests of
Gargoyle Specialists L.P. ("Gargoyle") for an aggregate purchase price of
$9,567,609. Gargoyle was a member of the American Stock Exchange and
operated as a specialist in options on this exchange. The excess purchase
price over fair value of net assets acquired of $6,567,609 has been
reflected as intangibles in the consolidated statements of financial
condition. The operations of Gargoyle are conducted in Arbitrade, L.L.C.
and Gargoyle was dissolved as of the date of acquisition.

The following unaudited pro forma operating results of the Company assume
that the Gargoyle acquisition had occurred at the beginning of each period
presented. In addition to combining the historical results of operations
of the two companies, the unaudited pro forma results include adjustments
for the estimated effect of purchase accounting on the Company's results.

Nine months ended Year ended December 31
(in millions) September 30, 1999 1998 1997

Net revenues $ 70.8 $ 63.8 $ 50.3
Net income 40.0 35.9 29.1

The unaudited pro forma information may not be indicative of the results
that actually would have occurred if the combination had been in effect on
the dates indicated or which may be obtained in the future.

7. Related Party Transactions

Members of Holdings may receive loans from Holdings. These loans, which are
payable on demand, are charged interest based on 6% per annum of the loan
amount. Interest income on these loans is included in other income in the
consolidated statements of operations and amounted to $638,865 for the nine
months ended September 30, 1999, $527,827 for the year ended December 31,
1998 and $0 for the year ended December 31, 1997.

Certain personnel and administrative expenses incurred by the investment
managers of the private investment funds are charged to the funds. Such
expenses totaled $1,160,313 for the nine months ended September 30, 1999,
and $2,450,702 and $1,633,765 for the years ended December 31, 1998 and
1997, respectively.

8. Regulatory Matters

Arbitrade, L.L.C. is subject to the Securities and Exchange Commission's
("SEC") Uniform Net Capital Rule ("Rule 15c3-1"), which requires the
maintenance of minimum net capital. Arbitrade, L.L.C. has elected to
compute net capital using the alternative method, permitted by the Rule,
which requires that Arbitrade, L.L.C. maintain minimum net capital, as
defined, equal to $250,000. At September 30, 1999, Arbitrade, L.L.C. had
net capital and net capital requirements of approximately $9,529,000 and
$250,000, respectively.

Arbitrade U.K. Ltd. is also subject to capital adequacy requirements of the
Securities and Futures Authority Limited in the United Kingdom. As of
September 30, 1999, Arbitrade U.K. Ltd. was in compliance with its capital
adequacy requirements.

Advances, dividend payments and other equity distributions from regulated
subsidiaries may be restricted by the regulations of various regulatory
agencies. These restrictions may limit the amounts that these subsidiaries
pay as dividends or advances to Holdings.

9. Commitments and Contingencies

The Company rents office space under leases containing operating expense
escalation clauses. The Company's principal lease is cancelable upon 90
days' written notice. At September 30, 1999, future non-cancelable minimum
commitments under leases with remaining terms exceeding one year were as
follows:

Three months ended December 31, 1999 $ 168,761
2000 664,727
2001 453,726
2002 374,935
2003 323,557
2004 307,539
Thereafter 396,359
-----------
$2,689,604
===========

Rent expense for the nine months ended September 30, 1999 was $354,436 and
for the years ended December 31, 1998 and 1997 was $300,947 and $257,366,
respectively.

In 1999, the Company purchased Class A and Class B membership units in the
International Securities Exchange LLC (ISE) for an aggregate purchase price
of $22,500,000. The Company has paid $375,000, with the balance to be paid
based on and contingent upon trades executed on the ISE. The ISE is not
currently operational and there is no definitive date set for the
commencement of its operations.

Although the Company is a defendant in legal proceedings arising out of the
normal course of business, there are no legal proceedings which, in the
opinion of management and counsel, would have a material impact on the
Company's consolidated financial statements.

10. Employee Benefit Plan

The Company sponsors a 401(k) profit sharing plan (the "Plan") in which
substantially all of its employees are eligible to participate. Under the
terms of the Plan, the Company is required to make annual contributions to
the Plan equal to 50% of the contributions made by its employees, up to
certain limitations. The total expense with respect to the Plan for the
nine months ended September 30, 1999 and the years ended December 31, 1998
and 1997 was $150,000, $71,000 and $0, respectively.

11. Members' Equity

At September 30, 1999, December 31, 1998 and January 1, 1998 there were
1,000 Class A units of membership interests ("working interests")
outstanding. At September 30, 1999, December 31, 1998 and January 1, 1998
there were 55,000,000, 33,899,432 and 42,374,289 Class B units of
membership interests ("capital interests") outstanding, respectively. Both
classes have voting rights and share in the allocation of net income or
loss of the Company, as defined in the LLC Operating Agreement. Only Class
B units represent ownership in the equity of the Company.

As of December 31, 1998, one member terminated his interest in the Company
and redeemed his Class B capital interests. This redemption, totaling
$8,474,857, is included in accrued expenses and other liabilities at
December 31, 1998 in the consolidated statements of financial condition.

Effective January 1, 1999, a total of 15,950,000 Class B units of
membership interests were issued to three new members and an additional
5,150,568 Class B units of membership interests were issued to two existing
members. At September 30, 1999, a receivable from one new member and two
existing members for $6,843,941 to purchase Class B units of membership
interests has been netted in members' equity in the consolidated statements
of financial condition. As of December 20, 1999, $279,474 of the receivable
remained unpaid.

12. Derivative Financial Instruments

Derivative contracts are financial instruments whose value is based upon an
underlying asset, index, reference rate or a combination of these factors.
The Company uses derivative financial instruments as part of its market-
making and trading business and its overall risk management process. These
financial instruments, which generally include exchange-traded options,
options on futures and futures contracts, expose the Company to varying
degrees of market and credit risk. The Company records its derivative
trading activities at market value and unrealized gains and losses are
recognized currently.

13. Agreements with Clearing Brokers

The Company has clearing agreements with three clearing brokers. The
Company earns interest income and/or incurs interest expense on
substantially all balances due from/to these clearing brokers. At September
30, 1999 and December 31, 1998, substantially all of the Company's
securities owned, securities sold, not yet purchased and
receivables/payables from/to clearing brokers are amounts held by or due
from/to these clearing brokers.

14. Business Segment and Geographic Information

The Company has two reportable segments: market making and trading, and
asset management. The market making and trading segment includes the
operations of Arbitrade, L.L.C., Arbitrade U.K Ltd. and Gmbh, and includes
market making in options and trading in equities, debt instruments and
related exchange-traded derivatives. The asset management segment includes
the operations of Deephaven Capital Management LLC, Deephaven Capital LLC
and Deephaven Investment Advisers LLC (or its predecessor entities) and
consists of investment management operations and sponsorships for a series
of private investment funds.

The Company evaluates performance and allocates resources based on profit
from operations before income taxes. The accounting policies of the
reportable segments are the same as those described in the summary of
significant accounting policies. The Company's revenues, net revenues,
income (loss) before income taxes and assets by segment are summarized

15. Subsequent Events

On November 17, 1999, the Company signed a definitive agreement to merge
with Knight/Trimark Group, Inc. The transaction is subject to regulatory
approval and is expected to close in early 2000.

16. Year 2000 Readiness Disclosure (Unaudited)

Like other financial and business organizations worldwide, the Company
could be adversely affected if computer systems on which the Company
relies, which primarily include those used by the Company and its service
providers, are unable to correctly process date-related information on and
after January 1, 2000. This risk is commonly called the Year 2000 Issue.
Failure to successfully address the Year 2000 Issue could result in
interruptions to, and other material adverse effects on, the Company's
business and operations. The Company has commenced a review of the Year
2000 Issue as it may affect its business and is taking steps it believes
are reasonably designed to address the Year 2000 Issue, although there can
be no assurances that these steps will be sufficient. In addition, there
can be no assurances that the Year 2000 Issue will not have an adverse
effect on the companies whose securities are held by the Company or on
global markets or economies generally.

Item 7(b). Unaudited Pro Forma Condensed Combined Financial Statement
Information

The following unaudited Pro Forma Condensed Combined Statement of
Financial Condition and unaudited Pro Forma Condensed Combined Statements
of Operations ("Pro Forma Condensed Combined Financial Statement
Information") are based upon the historical consolidated financial
statements of Knight/Trimark Group, Inc. ("Knight/Trimark") and Arbitrade
Holdings LLC ("Arbitrade").

The historical information for Knight/Trimark included in the Unaudited
Pro Forma Condensed Combined Statement of Financial Condition as of
September 30, 1999 and the Unaudited Pro Forma Condensed Combined Statement
of Operations for the nine months ended September 30, 1999 is derived from
the unaudited consolidated financial statements of Knight/Trimark which, in
the opinion of management, have been prepared on the same basis as the
audited consolidated financial statements of Knight/Trimark for the years
ended December 31, 1998 and 1997, and contain all adjustments, consisting
only of normal recurring adjustments, necessary for a fair presentation of
the results of operations for such period. The historical information for
Knight/Trimark included in the Unaudited Pro Forma Condensed Combined
Statements of Operations for the years ended December 31, 1998 and 1997
have been derived from the audited consolidated financial statements of
Knight/Trimark for the years ended December 31, 1998 and 1997, which
statements are not included in this Form 8-K.

The historical information for Arbitrade included in the Unaudited Pro
Forma Condensed Combined Statement of Financial Condition as of September
30, 1999 and the Unaudited Pro Forma Condensed Combined Statements of
Operations for the nine months ended September 30, 1999 and for the years
ended December 31, 1998 and 1997 have been derived from the audited
consolidated financial statements of Arbitrade for such periods, which
statements are included elsewhere in this Form 8-K.

The unaudited Pro Forma Condensed Combined Statement of Financial
Condition as of September 30, 1999 gives pro forma effect to the merger of
a wholly owned subsidiary of Knight/Trimark with and into Arbitrade (the
"Merger") and the issuance of 10,505,001 shares of Knight/Trimark class A
common stock to the holders of the outstanding class B membership interests
of Arbitrade as if such transactions occurred as of September 30, 1999.
The Merger will be accounted for as a pooling of interests.

The unaudited Pro Forma Condensed Combined Statements of Operations for
the nine months ended September 30, 1999 and for the years ended December
31, 1998 and 1997 give pro forma effect to the Merger as if it occurred as
of January 1, 1997.

The unaudited Pro Forma Condensed Combined Financial Statement
Information and accompanying notes should be read in conjunction with the
historical consolidated financial statements of Knight/Trimark and
Arbitrade. The unaudited Pro Forma Condensed Combined Financial Statement
Information presented is not necessarily indicative of the results of
operations that might have occurred had the Merger actually taken place as
of the dates specified, or that may be expected to occur in the future.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements

1. BASIS OF PREPARATION

As permitted by the rules and regulations of the Securities and Exchange
Commission, the Unaudited Pro Forma Condensed Combined Statement of
Financial Condition and Unaudited Pro Forma Condensed Combined Statements
of Operations are presented on a condensed basis.

2. PRO FORMA ADJUSTMENTS

(a) Stockholders' Equity / Members' Equity - Adjustments to reflect the
issuance of 10,505,001 shares of Knight/Trimark class A common stock in the
Merger, and the estimated distributions payable to members of Arbitrade
from undistributed income of Arbitrade in accordance with Arbitrade's
annual distribution policy as if September 30, 1999 was the end of
Arbitrade's fiscal period.

(b) Compensation and Benefits for Arbitrade's Members - As Arbitrade has
operated historically as a limited liability company ("LLC"), compensation
and benefits to Arbitrade's members ("Members' Compensation") was accounted
for as distributions of members' equity rather than as compensation
expense. As a result, the historical compensation expense and income
before income taxes of Arbitrade for the periods presented did not reflect
Members' Compensation.

In connection with the closing of the Merger, each of Arbitrade's members
signed an employment agreement with Arbitrade, which will become effective
as of the closing date of the Merger. Such employment agreements entitle
Arbitrade's members to annual compensation that includes a base salary and
participation in Arbitrade's sub-pool of the Knight/Trimark Profit-Pool
Incentive Plan. Arbitrade's sub-pool will equal 15% of the before-tax
profits earned by Arbitrade during each fiscal quarter, and will be
allocated on a quarterly basis by the executive officers of Arbitrade.

Accordingly, Knight/Trimark has estimated the historical compensation
expense for Arbitrade's members for the periods presented based on the
employment agreements with Arbitrade's members discussed above. As a
result, pro forma compensation and benefits expense of $6,705,707,
$5,096,915 and $4,646,837 has been recorded on the Unaudited Pro Forma

Condensed Combined Statements of Operations for the nine months ended
September 30, 1999 and for the years ended December 31, 1998 and 1997,
respectively.

(c) Pro Forma Provision for Income Taxes - As Arbitrade has operated as an
LLC since inception, the historical results for all periods presented have
been adjusted to reflect a pro forma provision for income taxes at an
effective tax rate of 42.5% for Arbitrade. Prior to its initial public
offering in July 1998, Knight/Trimark also operated as an LLC.
Accordingly, the historical statement of operations for the years ended
December 1997 and 1998 reflect a pro forma provision for income taxes as if
Knight/Trimark was a taxable entity for all periods presented.

(d) Pro Forma Basic and Diluted Average Common Shares Outstanding -
Adjustments to the shares used in the basic and diluted earnings per share
calculations for the periods presented to reflect the Knight/Trimark class
A common stock that would have been issued in exchange for outstanding
class B membership interests of Arbitrade based on the exchange ratio
applicable upon the closing of the Merger.

ARTICLE II
EFFECT OF THE MERGERS ON THE EQUITY SECURITIES OF
KT AND AH; CERTIFICATES

Section 2.1 Effect on KT Stock and SubKT Stock. As of the KT
Effective Time, by virtue of the KT Merger and without any action on the
part of SubKT, KT or the holders of any securities of SubKT or KT:

(a) Cancellation of Treasury Stock. Each share of KT Class A
Common Stock that is owned directly by KT (but not including any such
shares owned by employee benefit or pension plans) shall automatically be
cancelled and retired and shall cease to exist, and no consideration shall
be delivered in exchange therefor.

(b) Conversion of KT Class A Common Stock. Each issued and
outstanding share of KT Class A Common Stock (other than shares to be
cancelled in accordance with Section 2.1(a)) shall be converted into one
(the "KT Merger Exchange Ratio") validly issued, fully paid and
nonassessable share of Parent Common Stock (such consideration being
referred to herein as the "KT Merger Consideration"). As of the KT
Effective Time, all such shares of KT Class A Common Stock shall no longer
be outstanding and shall automatically be cancelled and retired and shall
cease to exist, and each certificate or certificates which immediately
prior to the Effective Time represented outstanding shares of KT Class A
Common Stock (the "KT Certificates") shall cease to represent such shares
of KT Class A Common Stock and instead shall be deemed to be certificates
("Parent Certificates") representing the number of whole shares of Parent
Common Stock into which such shares have been converted.

(c) Conversion of Common Stock of SubKT. Each issued and
outstanding share of common stock, par value $.01 per share, of SubKT shall
be converted into one validly issued, fully paid and nonassessable share of
common stock of Surviving Corporation.

(d) Cancellation of Parent Common Stock Owned by KT. Each share
of Parent Common Stock that is owned by KT immediately prior to the KT
Effective Time shall automatically be cancelled and retired and shall cease
to exist, and no consideration shall be delivered in exchange therefor.

Section 2.2 Effect on AH Membership Units and SubAH Membership
Interests. As of the AH Effective Time, by virtue of the AH Merger and
without any action on the part of SubAH, AH or the holders of any
securities of SubAH or AH:

(a) Cancellation of Unissued Interests. Each unissued AH
Membership Unit shall automatically be cancelled and retired and shall
cease to exist, and no consideration shall be delivered in exchange
therefor.

(b) Conversion of AH Membership Units. Subject to Section
2.3(e), each issued and outstanding AH Membership Unit set forth in Section
3.2(a)(i) of the AH Disclosure Schedule (as hereinafter defined in Article
III) (other than membership units to be cancelled in accordance with
Section 2.2(a)) shall be converted into such fraction (the "AH Merger
Exchange Ratio") of a validly issued, fully paid and nonassessable share of
Parent Common Stock (such consideration being referred to herein as the "AH
Merger Consideration," and, collectively with the KT Merger Consideration,
the "Merger Consideration") as determined in accordance with the next
sentence. The AH Merger Exchange Ratio shall be determined as follows: (i)
if the Average Price (as defined below) is greater than or equal to
$23.450, but less than or equal to $35.175, then the AH Merger Exchange
Ratio will be the quotient determined by dividing 6.727 by the Average
Price; (ii) if the Average Price is less than $23.450, then the AH Merger
Exchange Ratio will be 0.287; and (iii) if the Average Price is greater
than $35.175, then the AH Merger Exchange Ratio will be 0.191. "Average
Price" means the average (rounded to the nearest 1/10,000) of the closing
prices on The Nasdaq Stock Market's National Market (the "NMS") as reported
in The Wall Street Journal (national edition) (or if not reported thereby,
any other authoritative source), of the KT Class A Common Stock for the ten
consecutive trading days ending on the third trading day immediately prior
to the KT Effective Time. In determining the AH Merger Exchange Ratio
pursuant to clause (i) as provided above, the final number will be rounded
to three decimal places, rounding up from 0.0005. Notwithstanding anything
elsewhere herein to the contrary, the aggregate number of shares of Parent
Common Stock to be issued to each holder of AH Membership Units shall be
rounded to the nearest whole number of shares. As of the AH Effective
Time, all such AH Membership Units shall no longer be outstanding and shall
automatically be cancelled and retired and shall cease to exist, and each
holder of an AH Membership Unit immediately prior to the AH Effective Time
shall cease to have any rights with respect thereto, except the right to
receive Parent Certificates.

(c) Cancellation of AH Class A Membership Units. Each issued
and outstanding class A membership unit of AH (the "Class A Membership
Units"), shall automatically be cancelled and retired and shall cease to
exist, and no consideration shall be delivered in exchange therefor.

(d) Conversion of Membership Interests of SubAH. Each issued
and outstanding membership interest of SubAH shall be converted into one
validly issued, fully paid and nonassessable membership interest of the
Surviving LLC.

Section 2.3 Exchange of Certificates.

(a) No Surrender of KT Certificates. Until thereafter
surrendered for transfer or exchange in the ordinary course, each
outstanding stock certificate that, immediately prior to the KT Effective
Time, evidenced shares of KT Class A Common Stock shall be deemed and
treated for all corporate purposes to evidence the ownership of the number
of shares of Parent Common Stock into which such shares of KT Class A
Common Stock were converted pursuant to the provisions of Section 2.1(b).

(b) Exchange Agent. As of the AH Effective Time, Parent shall
enter into an agreement with such bank or trust company as may be
designated by KT (the "Exchange Agent"), which shall provide that Parent
shall deposit with the Exchange Agent as of the AH Effective Time, for the
benefit of the holders of AH Membership Units, for exchange in accordance
with this Article II, through the Exchange Agent, Parent Certificates
representing the number of whole shares of Parent Common Stock issuable
pursuant to Section 2.2(b) in exchange for outstanding AH Membership Units.

(c) Exchange Procedures. At the AH Effective Time and subject
to the provisions of Section 2.3(g) below, each holder of AH Membership
Units whose AH Membership Units were converted into AH Merger Consideration
pursuant to Section 2.2(b) hereof shall receive from the Exchange Agent a
Parent Certificate representing that number of whole shares of Parent
Common Stock which such holder has the right to receive pursuant to the
provisions of Section 2.2(b) hereof; provided, that each such holder shall
execute an acknowledgment, in form and substance reasonably satisfactory to
Parent, stating that receipt of such Parent Certificate by such holder
shall be deemed in full satisfaction of the obligations of Parent to such
holder under Article II. Until surrendered for exchange as contemplated by
this Section 2.3, each AH Membership Unit shall be deemed at any time after
the AH Effective Time to represent only the right to receive upon such
surrender, Parent Certificates representing the number of whole shares of
Parent Common Stock into which the AH Membership Units have been converted.

(d) No Further Ownership Rights in AH Membership Units. All
shares of Parent Common Stock issued upon the surrender for exchange of AH
Membership Units in accordance with the terms of this Article II shall be
deemed to have been issued in full satisfaction of all rights pertaining to
the AH Membership Units, and there shall be no further registration of
transfers on the transfer books of the Surviving LLC of the AH Membership
Units which were outstanding immediately prior to the AH Effective Time.
If, after the AH Effective Time, AH Membership Units are presented to the
Surviving LLC or the Exchange Agent for any reason, they shall be cancelled
and exchanged as provided in this Article II, except as otherwise provided
by Law.

(e) No Fractional Shares. No Parent Certificates or scrip
representing fractional shares of Parent Common Stock shall be issued upon
the surrender for exchange of AH Membership Units, no dividend or
distribution of Parent shall relate to such fractional share interests, and
such fractional share interests will not entitle the owner thereof to vote
or to any rights of a stockholder of Parent.

(f) No Liability. None of Parent, KT, AH or the Exchange Agent
shall be liable to any person in respect of any shares of Parent Common
Stock (or dividends or distributions with respect thereto), in each case
delivered to a public official pursuant to any applicable abandoned
property, escheat or similar Law.

(g) Escrow Indemnity Agreement. Each of the Members hereby
agrees to cause the Exchange Agent (by written instruction and such other
actions reasonably requested by the Exchange Agent and the Escrow Agent) to
deposit, at the AH Closing, with an escrow agent reasonably acceptable to
Parent and AH (the "Escrow Agent"), on behalf of the Members, a number of
shares of Parent Common Stock equal to 10% of the aggregate number of
shares of Parent Common Stock issuable to the Members pursuant to Section
2.2 hereof (the "Escrow Shares"), which Escrow Shares shall be held in an
escrow account in accordance with the terms of an escrow agreement between
the Members, Parent and the Escrow Agent, substantially in the form
attached as Exhibit C hereto (the "Escrow Indemnity Agreement"). The
obligations of each of the Members to cause the deposit of shares of Parent
Common Stock as Escrow Shares shall be pro rata to the number of shares of
Parent Common Stock to which such Member (directly or through any
affiliated entity) is entitled as a result of the AH Merger. The Escrow
Shares will secure the obligations of the Members pursuant to Article VIII.

ARTICLE III
REPRESENTATIONS AND WARRANTIES OF AH AND THE MEMBERS

Except as set forth in the disclosure schedule delivered by AH
prior to the execution of this Agreement (the "AH Disclosure Schedule")
making reference to the particular section or subsection of this Agreement
to which an exception is being taken, AH and each of the Members hereby
represent and warrant, jointly and severally, to KT, as of the date hereof
and as of the AH Closing Date, as follows:

Section 3.1 Organization, Qualification, Etc.

(a) AH is a limited liability company duly organized, validly
existing and in good standing (or other equivalent status) under the laws
of the jurisdiction of its organization and has the limited liability
company power and authority to own, operate and lease all of its properties
and assets and to carry on its business as it is now being conducted or
presently proposed to be conducted and is duly qualified to do business and
is in good standing (or other equivalent status) in each jurisdiction in
which the ownership, operation or leasing of its properties or assets or
the conduct of its business requires such qualification, except for
jurisdictions in which the failure to be so qualified or in good standing
(or other equivalent status) could not reasonably be expected, individually
or in the aggregate, to have a Material Adverse Effect on AH. As used in
this Agreement, any reference to any state of facts, event, change or
effect having a "Material Adverse Effect" on or with respect to AH, means
such state of facts, event, change or effect that, individually or in the
aggregate, has had or could reasonably be expected to have a material
adverse effect on the business, assets, results of operations or condition
(financial or otherwise) of AH and its Subsidiaries (as hereinafter
defined), taken as a whole (except for any state of facts, event, change or
effect (i) relating to general economic conditions in the geographic areas
in which AH and its Subsidiaries operate or invest or (ii) similarly
affecting persons in the industries in which AH and its Subsidiaries
operate), or that could reasonably be expected to materially impair the
ability of AH or any of the Members to perform its respective obligations
under this Agreement or consummate the Mergers and the other transactions
contemplated hereby. AH has made available to KT true, complete and
correct copies of AH's Certificate of Formation and Amended and Restated
Operating Agreement (the "AH Organizational Documents"), which AH

Subsidiaries is the record owner of each such registration and application.

conduct its business in order to accommodate a third party's Intellectual
Property rights.

(f) AH has taken commercially reasonable actions (which the

incorrect results when processing, calculating, comparing, sequencing,
displaying, storing, providing, and/or receiving (i) date-related data into

other benefits plan, any of the benefits of which will be increased, or the
vesting of the benefits of which will be accelerated, by the occurrence of

Section 3.18 Real Property. Neither AH nor any of its
Subsidiaries owns any fee interest in real estate. Except as set forth in

any party thereunder). Assuming the due authorization, execution and
delivery by the other parties thereto, each AH Real Property Lease
constitutes the valid and legally binding obligation of AH or the relevant
Subsidiary, enforceable in accordance with its terms, subject to
bankruptcy, insolvency, reorganization, moratorium or other laws now or
hereafter in effect relating to creditors' rights generally or to general
principles of equity, and is in full force and effect. All material
amounts payable by AH and its Subsidiaries as tenants under each AH Real
Property Lease are current, and no termination event or condition or

except (i) Taxes and general and special assessments not in default and
payable without penalty and interest, (ii) Encumbrances under applicable

the Investment Company Act, and, accordingly, neither AH nor any of its
Subsidiaries is required to be registered under the Investment Company Act.

Section 3.20 Brokers. Except as set forth in Section 3.20 of
the AH Disclosure Schedule, no broker, finder or investment banker is
entitled to any brokerage, finder's or other fee or commission in

a complete and correct copy of all agreements between AH or any of the

administrative services and other services agreements, if any, and
organizational and offering documents, pertaining to each of the Private
Funds (i) have been made available to KT and (ii) are in full force and
effect. Such offering materials did not, at the respective dates thereof,
or at any time at which such materials were distributed or made available
to investors or prospective investors, contain any untrue statement of a
material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading. Except for the
Private Funds, neither AH nor any of its Subsidiaries is affiliated with,
or otherwise provides investment advisory or other Investment Management
Services to, any person.

(b) Each of the Private Funds is duly organized, validly
existing and in good standing in the jurisdiction in which it is organized
and has all requisite power and authority to conduct its business in the

business of investing and reinvesting in securities and, in the case of the

Governmental Entity for any taxable period (whether or not shown on any
Private Fund Tax Return) have been timely paid in full or are being
contested in good faith by appropriate proceedings. With respect to each
Private Fund, there are no liabilities for Taxes which have not been paid
in prior periods or for which an adequate reserve for such liability does
not exist. To the knowledge of AH, no deficiencies for any Taxes have been

Statements"), in each case, for the current and the past three fiscal years
or such shorter period since inception. Each of the Investment Fund
Financial Statements (including all notes and schedules contained therein
or annexed thereto) has been prepared in accordance with GAAP consistently
applied with past practices, and each of the Non-Investment Fund Financial
Statements (including all notes and schedules contained therein or annexed
thereto) has been prepared on a basis consistent with the accounting
principles used in the preparation of the Investment Fund Financial
Statements. Each of the Private Fund Financial Statements (including all
notes and schedules contained therein or annexed thereto) is consistent
with the books and records of the applicable Private Fund, and fairly
presents the assets, liabilities and financial condition, the results of
operations and cash flows of the applicable Private Fund as of the dates
and for the years and periods indicated. The Private Fund Financial
Statements reflect and disclose all material changes in accounting
principles and practices adopted by the applicable Private Fund during the
periods covered by each Private Fund Financial Statement. The books of
account of each of the Private Funds fairly reflect their respective
transactions.

(e) There are no consent judgments or regulatory orders on, or
with regard to, any of the Private Funds. Since inception, each of the
Private Funds has been excluded from the definition of an investment
company under the Investment Company Act by virtue of the respective
exemptions thereto set forth in Section 3.21(e) of the AH Disclosure
Schedule and, except as could not reasonably be expected, individually or

and restrictions, to the extent applicable and in effect at the time such
investments were held.

investigation at law or in equity pending or, to the knowledge of AH,

As of their respective dates, such reports and proxy statements

of the SEC Reports contains any untrue statement of a material fact or

books and records of KT and its Subsidiaries, and fairly present in all

limitations or waiting periods in effect under comparable Employee Benefit
Plans have not been satisfied as of the Effective Time, (ii) provide each
AH Employee with credit for any co-payments and deductibles paid prior to

which provide for grants of equity-based awards shall be amended or
converted into a similar instrument of Parent, in each case with such
adjustments to the terms of such KT Awards as are appropriate to preserve
the value inherent in such KT Awards with no detrimental effects on the
holders thereof. The other terms of each KT Award, and the plans or
agreements under which they were issued, shall continue to apply in
accordance with their terms, including any provisions providing for
acceleration of vesting or payment. With respect to any restricted stock

shares of Parent Common Stock on a basis consistent with the transactions
contemplated by this Agreement. At or prior to the KT Effective Time,
Parent shall take all corporate action necessary to reserve for issuance a

Effective Time, Parent shall either (i) file one or more registration
statements on Form S-1, Form S-3 or Form S-8, as the case may be (or any
successor or other appropriate forms), or (ii) take such action as is
required under Rule 414 under the Securities Act (or any successor
provision) to permit Parent to succeed to the existing registration
statement on Form S-8 of KT, in each case, with respect to the Parent
Common Stock subject to such KT Stock Options, and shall maintain the
effectiveness of such registration statements and the current status of the
prospectus or prospectuses contained therein, for so long as such KT Stock
Options remain outstanding.

conditions herein provided, AH and KT shall (a) promptly make all filings

efforts to cooperate with one another in (i) determining whether any

governmental or regulatory bodies or authorities of federal, state, local
and foreign jurisdictions in connection with the execution and delivery of

Members, on the one hand, and KT, on the other hand, shall promptly notify

delay the transactions contemplated hereby or which could reasonably be
expected to dilute the benefits to Parent and KT of the transactions
contemplated hereby, in each case other than the transactions contemplated
by this Agreement.

with any parties conducted heretofore with respect to any possible Takeover

policy (the "AH Policy") covering those persons who are currently covered
by the AH Policy (a copy of which has been heretofore delivered to Parent
and KT); provided, however, that in no event shall Parent be required to
expend in any one year an amount in excess of 150% of the annual premiums
currently paid by AH for such insurance, and, provided, further, that if
the annual premiums of such insurance coverage exceed such amount, Parent
shall be obligated to obtain a policy with the greatest coverage available
for a cost not exceeding such amount; and provided, further, that Parent
may meet its obligations under this paragraph by covering the above people
under Parent's or one of its Significant Subsidiaries' insurance policy or
policies on the terms described above.

(c) Parent agrees that all rights to exculpation and
indemnification for acts or omissions occurring prior to the KT Effective
Time now existing in favor of the current or former directors or officers
of KT (the "KT Indemnified Parties") as provided in its charter or bylaws
or in any agreement shall survive the KT Merger and shall continue in full
force and effect in accordance with their terms. For six years from the KT
Effective Time, Parent shall indemnify the KT Indemnified Parties to the
same extent as such KT Indemnified Parties are entitled to indemnification
pursuant to the preceding sentence.

(d) For three years from the KT Effective Time, Parent shall
maintain in effect KT's current directors' and officers' liability
insurance policy (the "KT Policy"), covering those persons who are covered
by the KT Policy (a copy of which has been heretofore delivered to Parent
and AH); provided, however, that in no event shall Parent be required to
expend in any one year an amount in excess of 150% of the annual premiums
to be paid by KT for such insurance, and, provided, further, that if the
annual premiums of such insurance coverage exceed such amount, Parent shall
be obligated to obtain a policy with the greatest coverage available for a
cost not exceeding such amount; and provided, further, that Parent may meet
its obligations under this paragraph by covering the above people under
Parent's or one of its Significant Subsidiaries' insurance policy or
policies on the terms described above.

Section 5.13 Section 16(b). KT and Parent shall take all steps
reasonably necessary to cause the transactions contemplated hereby and any
other dispositions of equity securities of KT (including derivative
securities) or acquisitions of Parent equity securities (including
derivative securities) in connection with this Agreement by each individual
who (a) is a director or officer of KT or (b) at the KT Effective Time,
will become a director or officer of Parent, to be exempt under Rule 16b-3
promulgated under the Exchange Act.

Section 5.14 Members' Non-Compete.

(a) Each of the Members acknowledges that the covenants in this
Section 5.14 are an essential element of the Mergers and a fundamental
inducement to Parent to enter into this Agreement. Moreover, each of the
Members acknowledges that the business of AH or KT is or can be conducted
in any location throughout the United States, Europe or anywhere else in
the world.

(b) Without the express prior written consent of Parent, none of
the Members shall, at any time during the five-year period immediately
following the AH Closing Date, directly or indirectly, engage in, or
otherwise directly or indirectly be employed by or act as a consultant or
lender to, or be a director, officer, principal, agent, stockholder,
member, owner or partner of, or permit his name to be used in connection
with the activities of, or be related to or otherwise affiliated in any
manner with, any other business or organization anywhere in the world which
competes, directly or indirectly, with the business of AH or KT; provided,
that the foregoing shall not prohibit (i) the Members from, individually or
collectively, owning as a passive investment 5% or less of the equity of
any publicly-traded entity or (ii) each Member from providing investment
consulting services to such Member and the members of his family (and
employing up to five individuals in trading activities related thereto), in
the case of clause (ii), to the extent that such provision or employment
does not violate or interfere with any obligations of such Member to Parent
or any of its Subsidiaries.

(c) If it is ever held that the restriction placed on any Member
by this Section 5.14 is too onerous and is not necessary for the protection
of the other party or parties hereto, each party to this Agreement agrees
that any court of competent jurisdiction may impose lesser restrictions
which such court may consider to be necessary or appropriate to properly
protect the other party of parties hereto.

Section 5.15 Non-Solicitation of Employees.

(a) Each of the Members acknowledges that the covenants in this
Section 5.15 are an essential element of the Mergers and a fundamental
inducement to Parent to enter into this Agreement.

(b) From and after the date hereof, none of the Members shall,
without the express prior written consent of Parent, for a period of five
(5) years from the AH Closing Date, directly or indirectly solicit,
encourage, entice or induce any person who is an employee or consultant of
AH or any of its Subsidiaries at or subsequent to the date hereof, to
terminate his or her employment or consultancy with Parent or any of its
Subsidiaries or directly or indirectly hire or employ any person who is an
employee or consultant of AH or any of the Subsidiaries at the date hereof
or who become an employee or consultant of AH or any of the Subsidiaries
after the date hereof; provided, that the foregoing shall not in any manner
restrict managerial determinations regarding employment matters by Members
who are then employees of Parent or any of its Subsidiaries.

(c) If it is ever held that the restriction placed on any Member
by this Section 5.15 is too onerous and is not necessary for the protection
of the other party or parties hereto, each party to this Agreement agrees
that any court of competent jurisdiction may impose lesser restrictions
which such court may consider to be necessary or appropriate to properly
protect the other party or parties hereto.

Section 5.16 Pooling Letters. Each of AH and KT will use its
reasonable best efforts to cause its respective independent public
accountants to deliver a customary "pooling-of-interests" letter, dated as
of the AH Closing Date.

Section 5.17 Resale Registration. Upon written request by the
Members, Parent shall use its reasonable best efforts to cause to become
effective, as soon as reasonably practicable after receipt of such request
(but in no event prior to the expiration of the Pooling Period (as defined
in the Affiliate Letter)), one shelf registration statement on Form S-3 for
the purpose of permitting resale (in accordance with the methods of
distribution reasonably requested by the Members) of up to 2,500,000 shares
of Parent Common Stock received pursuant hereto by the Members (to be
allocated pro rata among the Members or pursuant to such other allocation
agreed upon by the Members). The effectiveness of the Registration
Statement shall be maintained for so long as is necessary after the
Effective Time in order to permit such resales by the relevant Members, but
in no event beyond the first anniversary of the AH Effective Time. The
obligations of Parent to cause or maintain the effectiveness of such
registration statement and the ability of the relevant Members to execute
any transaction pursuant to such registration statement shall be subject to
reasonable delay if the Board of Directors and/or President of Parent
reasonably and in good faith determines that such effectiveness would (i)
require the disclosure of material information that the Company has a bona
fide business purpose for preserving as confidential or (ii) materially
interfere in a pending material transaction involving Parent and/or its
Subsidiaries.

terminated at any time prior to the AH Effective Time:

(a) by the mutual written consent of AH and KT;

(b) by either KT or AH if the AH Effective Time shall not have
occurred on or before September 30, 2000; provided, that the party seeking

breached in any material respect its obligations under this Agreement in
any manner that shall have proximately contributed to the failure to

(c) by either KT or AH if (i) a statute, rule, regulation or

States federal or state governmental body prohibiting the consummation of
the Mergers substantially on the terms contemplated hereby or (ii) an
order, decree, ruling or injunction shall have been entered by a United

(e) by AH, if there shall have been a material breach by KT of
any of its representations, warranties, covenants or agreements contained

6.2(b) would not be satisfied, and such breach (if curable) shall not have
been cured within 30 days after notice thereof shall have been received by
KT; or

(f) by KT, if there shall have been a material breach by AH or
any of the Members of their respective representations, warranties,

conditions set forth in Section 6.3(a) or 6.3(b) would not be satisfied,
and such breach (if curable) shall not have been cured within 30 days after
notice thereof shall have been received by AH.

Section 7.2 Effect of Termination. In the event of termination
of this Agreement pursuant to Section 7.1, this Agreement shall terminate
(except for the provisions of the penultimate sentence of Section 5.2 and
Sections 7.3 and 9.1), and there shall be no other liability on the part of
KT, on the one hand, and AH and the Members, on the other hand, to the
other except liability arising out of a wilful and material breach of this
Agreement or as provided for in the Confidentiality Agreement.

Section 7.3 Termination Fee.

(a) In the event that (i) this Agreement is terminated by KT
pursuant to Section 7.1(d), or (ii) this Agreement is terminated by KT
pursuant to Section 7.1(f) as a result of any wilful and material breach by
AH or any of its Subsidiaries or any Member of any representation,
warranty, covenant or agreement set forth in this Agreement, then AH and
the Members, jointly and severally, shall be obligated to promptly pay to
KT a fee equal to $10.0 million; provided, that if within twelve (12)
months after the date this Agreement is terminated under circumstances
described in clause (i) or (ii) above, AH, any of its Subsidiaries, any of
the Members or any of their respective affiliates enters into any letter of
intent, agreement in principle, acquisition agreement or other agreement
related to any Takeover Proposal or a Takeover Proposal is consummated with
any third party, then AH and the Members, jointly and severally, shall be
obligated to pay to KT an additional fee equal to $40.0 million (either
such fee, the "Termination Fee"), in each case payable by wire transfer of
same day funds. AH and the Members expressly acknowledge that the
agreements contained in this Section 7.3(a) are an integral part of the
transactions contemplated by this Agreement, and that, without these
agreements, KT would not enter into this Agreement; accordingly, if AH and
the Members fail promptly to pay the Termination Fee, and, in order to
obtain such payment, KT commences a suit which results in a judgment
against AH and/or the Members for the Termination Fee, AH and the Members
expressly shall be obligated, jointly and severally, to pay to KT its costs
and expenses (including attorneys' fees and expenses) in connection with
such suit, together with interest on the amount of the Termination Fee at
the prime rate of Citibank N.A. in effect on the date such payment was

agreement set forth in this Agreement, then KT shall be obligated to
promptly pay to AH a fee equal to $10.0 million (the "KT Termination Fee"),
payable by wire transfer of same day funds. KT expressly acknowledges that
the agreements contained in this Section 7.3(b) are an integral part of the
transactions contemplated by this Agreement, and that, without these
agreements, AH would not enter into this Agreement; accordingly, if KT
fails promptly to pay the KT Termination Fee, and, in order to obtain such
payment, AH commences a suit which results in a judgment against KT for the
KT Termination Fee, KT expressly shall be obligated to pay to AH its costs
and expenses (including attorneys' fees and expenses) in connection with
such suit, together with interest on the amount of the KT Termination Fee
at the prime rate of Citibank N.A. in effect on the date such payment was
required to be made.

(c) The payment of any fee pursuant to this Section 7.3 shall be
made to an account designated in writing by the party entitled to receive
such fee.

Section 7.4 Amendment or Supplement. At any time prior to the

of any other party contained herein or in any document delivered pursuant
hereto; or

(c) subject to the proviso of Section 7.4, waive compliance with
any of the agreements or conditions of the other party contained herein.

Notwithstanding the foregoing no failure or delay by any party in
exercising any right hereunder shall operate as a waiver thereof nor shall
any single or partial exercise thereof preclude any other or further
exercise thereof or the exercise of any other right hereunder. Any
agreement on the part of a party hereto to any such extension or waiver
shall be valid only if set forth in an instrument in writing signed on
behalf of such party.

ARTICLE VIII
INDEMNIFICATION

Section 8.1 Indemnification by the Members. Subject to Section
8.3 below and the terms of the Escrow Indemnity Agreement, each of the
Members shall jointly and severally indemnify Parent and its Subsidiaries
and their respective successors and permitted assigns and their respective
officers, directors, employees, agents and affiliates (other than the
Members and their affiliates) (collectively, the "Parent Indemnified
Parties") from and against and shall reimburse the same for and in respect
of any and all losses, reasonable costs, fines, liabilities, claims,
penalties, damages and reasonable expenses (including all legal fees and
expenses) of any nature or kind (collectively "Losses") which may be
claimed or assessed against any of them or to which any of them may be
subject, in connection with any and all claims, suits or asserted Losses
which are related to the inaccuracy or incompleteness of any representation
or warranty made by AH or any of the Members that is contained in or made
pursuant to Article III of this Agreement, any breach of any agreement or
covenant of AH or any of the Members contained in this Agreement, or any
claim of any former member of AH arising out of this Agreement and any
agreements executed in connection herewith and the transactions
contemplated hereby and thereby. Notwithstanding the preceding sentence,
the Members shall not be obligated under this Article VIII to indemnify the
Parent Indemnified Parties in respect of trading losses resulting from the
ordinary course of business trading activities.

Section 8.2 Indemnification Procedures.

(a) Notice. A party entitled to indemnification under this
Article VIII (an "Indemnified Party") agrees to give each party obligated
to provide indemnification pursuant to this Article VIII (an "Indemnifying
Party") prompt written notice (the "Claim Notice") of any claim, assertion,
event, condition or proceeding by or in respect of any third party (each, a
"Third Party Claim") of which it has knowledge concerning any liability or
damage as to which it may request indemnification hereunder. The Claim
Notice shall describe in reasonable detail the nature of the claim,
including an estimate, if practicable, of the amount of Losses that have
been or may be suffered or incurred by the Indemnified Party attributable
to such claim and the basis of the Indemnified Party's request for
indemnification under this Agreement.

(b) Conduct of Defense. An Indemnifying Party shall have the
right, upon written notice to the Indemnified Party (the "Defense Notice")
within ten business days of its receipt from the Indemnified Party of the
Claim Notice, to conduct at its expense the defense against such Third
Party Claim in its own name, or, if necessary, in the name of the
Indemnified Party. When the Indemnifying Party assumes the defense, the
Indemnified Party shall have the right to reasonably approve the defense
counsel and no such claim may be compromised or settled without the express
prior written consent of the Indemnified Party; provided, however, that in
any case in which the Indemnified Party withholds consent to any such
proposed compromise or settlement, thereafter the maximum liability of the
Indemnifying Party under this Article VIII to such Indemnified Party with
respect to the relevant Third Party Claim shall not exceed the amounts set
forth in such proposed compromise or settlement. In the event that the
Indemnifying Party does deliver a Defense Notice and thereby elects to
conduct the defense of such Third Party Claim, the Indemnified Party will
cooperate with and make available to the Indemnifying Party such
assistance, personnel, witnesses and materials as the Indemnifying Party
may reasonably request. Regardless of which party defends such Third Party
Claim, the other party shall have the right at its expense to participate
in the defense assisted by counsel of its own choosing. In the event that
the Indemnifying Party shall fail to give the Defense Notice within the
time prescribed by Section 8.2(b), the Indemnified Party shall have the
sole right to conduct such defense and the Indemnified Party may pay,
compromise or defend such claim or proceeding at the Indemnifying Party's
expense. In the event any Indemnified Party should have a claim against
any Indemnifying Party hereunder which does not involve a Third Party
Claim, the Indemnified Party shall promptly transmit to the Indemnifying
Party a written notice describing in reasonable detail the nature of the
claim and the basis of the Indemnified Party's request for indemnification
under this Agreement.

Section 8.3 Limitations on Indemnification. Any liabilities of
the Members pursuant to this Article VIII shall be satisfied pursuant to
the terms of the Escrow Indemnity Agreement, which shall be the exclusive
remedy available for satisfaction of any obligation of the Members pursuant
to this Article VIII. Notwithstanding anything to the contrary in the
charter, bylaws, other organizational documents, agreements (including,
without limitation, the New Employment Agreements), insurance policies
(including, without limitation, any directors' and officers' liability or
other similar insurance policy) or other instruments of Parent or any of
its Subsidiaries, no Member (or any of their respective affiliates) shall
have any right to indemnification or other recovery thereunder or otherwise
(whether as an officer, member, director, stockholder or in any other
capacity) from Parent or any of its Subsidiaries with respect to any matter
to the extent that the Members are liable, or would be liable but for the
limitations on indemnification and limitations on survival of
representations, warranties, covenants and agreements contained herein, to
any of the Parent Indemnified Parties under this Article VIII with respect
to such matter. The Members shall not be obligated to indemnify any of the
Parent Indemnified Parties pursuant to this Article VIII until the
aggregate Losses suffered by the Parent Indemnified Parties exceed $1.0
million, except to the extent that such Losses result from a wilful breach
of a representation, warranty, agreement or covenant of AH or any of the
Members; provided, however, that if at any time the aggregate Losses exceed
$1.0 million, the Members shall be obligated to indemnify the relevant
Parent Indemnified Parties for the full amount of such Losses in excess of
$500,000.

Section 8.4 Survival of Representations, Warranties and
Covenants. The representations and warranties of AH and the Members
contained in Article III hereof shall survive until the first anniversary
of the AH Effective Time (the "Expiration Date"), and no party may seek
indemnification under this Article VIII with respect to a breach of such a
representation or warranty after the Expiration Date. Notwithstanding
anything to the contrary contained herein, all representations and
warranties made by AH and the Members pursuant to Article III of this
Agreement, and the liability with respect thereto, shall not terminate with
respect to any claim, whether or not fixed as to liability or liquidated as
to amount, with respect to which such party has been given written notice
stating the nature of the claim prior to the date on which such
representation or warranty expires. The parties' respective covenants and
agreements contained in this Agreement or in any certificate, schedule,
list, exhibit, agreement, document or other writing delivered pursuant
hereto or in connection with the transactions contemplated hereby shall
survive indefinitely unless otherwise set forth herein or therein;
provided, however, that no party may seek indemnification under this
Article VIII with respect to any breach of such a covenant or agreement
after the Expiration Date, except with respect to any claim, whether or not
fixed as to liability or liquidated as to amount, with respect to which
such party has given written notice stating the nature of the claim prior
to the Expiration Date. Notwithstanding anything to the contrary in this
Agreement, (a) no investigation by a party shall affect the
representations, warranties, covenants and agreements of the other parties
under this Agreement or in any certificate, schedule, list, exhibit,
agreement, document or other writing delivered pursuant hereto or in
connection with the transactions contemplated hereby furnished or to be
furnished to the other parties and (b) such representations, warranties,
covenants and agreements shall not be affected or deemed waived by reason
of the consummation of the Mergers or of the fact that the other party or
parties knew or should have known that any of the same is or might be
inaccurate in any respect.

ARTICLE IX

or that the venue thereof may not be appropriate or that this Agreement or
any such document may not be enforced in or by such courts, and the parties
hereto irrevocably agree that all claims with respect to such action or

such parties and over the subject matter of such dispute and agree that
mailing of process or other papers in connection with any such action or
proceeding in the manner provided in Section 9.4 or in such other manner as

including, without limitation, specific performance, without bond or other
security being required.

Subsidiaries. Reference in this Agreement to the "knowledge" of KT shall
refer to the knowledge of each of the members of senior management of KT
and its Subsidiaries.

requires a Subsidiary of AH or a Private Fund to take any action, that
requirement shall be deemed to include an undertaking on the part of AH to
cause that Subsidiary or Private Fund to take that action. Whenever this
Agreement requires a Subsidiary of KT to take any action, that requirement
