"We are pleased to report our sixth consecutive quarter of record financial results for our options exchange business segment," said David Krell, ISE's President and Chief Executive Officer. "Our exceptional growth has been fueled by the increasing demand for our equity options and index options products which are integral components of investors' risk management and profit enhancement strategies. Our successful track record in developing and launching new and innovative products, for institutional and retail investors alike, has strengthened our leadership position in the options industry," said Krell.

"On July 27, 2007, our stockholders overwhelmingly approved our merger with Eurex. Once we have secured the remaining regulatory approvals required to finalize the merger, we will then join forces and leverage the strengths of both organizations to develop new and innovative products and expand our global footprint," concluded Krell.

"The management teams of both organizations are excited about the growth opportunities that will result from our pending merger," said Gary Katz, ISE's Chief Operating Officer. "We look forward to jointly building a global organization that is the industry leader across multiple asset classes. Our shared values and entrepreneurial cultures bode well for the future success of our company. We are very anxious to get started on realizing the opportunities that we have identified as we begin our partnership with Eurex."

Second Quarter Results - Options Exchange

Income Statement

Revenues

Transaction fee revenues increased to $46.4 million from $40.7 million last year due to continued strong growth in trading volumes. Average daily trading volume increased to 2.9 million contracts from 2.4 million contracts last year. Other member fees increased to $7.1 million from $6.3 million in the same period last year due to an increase in connectivity fees which are charged to market makers based on quote capacity usage. Market data revenues increased to $4.4 million from $4.1 million in the prior year quarter due to our increased pro-rata share of OPRA revenues, based on our higher market share of trades, as well as increased OPRA profitability.

Cost of Revenues, Gross Margin

Cost of revenues for the second quarter decreased to $2.8 million from $6.0 million in the prior year quarter due to a decrease in licensing fees. Gross margin increased to $55.2 million from $45.1 million in the second quarter of 2006.

Expenses

Total expenses for the second quarter of 2007 increased to $28.5 million from $22.2 million in the second quarter of 2006. Included in our options exchange segment are corporate overhead costs, including merger related advisory expenses of $2.1 million.

Total direct expenses increased to $26.4 million from $22.1 million in the same period last year. Compensation and benefits expenses increased to $13.7 million from $11.4 million in the second quarter last year due to higher incentive compensation expenses resulting from increased profitability and increased headcount. Technology and communications expenses increased to $4.3 million from $3.7 million due to increased capacity costs attributable to increased quoting activity and enhancements for our trading system. Professional fees increased to $1.8 million from $1.4 million due to higher legal costs.

Depreciation and amortization increased to $2.7 million from $1.8 million primarily due to a $0.9 million, or $0.01 per diluted share (net of tax), asset impairment charge related to our decision to suspend operations of the Longitude trading platform. We suspended conducting auctions on the Longitude platform in June, and we are evaluating the prospects of new products that lend themselves to the pari-mutuel principles that form the core of our Alternative Markets business.

Other expenses increased to $1.9 million from $1.5 million last year principally due to settlement of a state tax audit.

Income, Margins and Taxes

Pre-tax income for the second quarter of 2007 increased to $29.7 million from $ 24.7 million last year. Interest and investment income increased to $3.1 million from $1.5 million primarily due to interest income from higher cash balances.

Our pre-tax margin for the options exchange segment of our business in the second quarter was 53.8%. Our proforma pre-tax margin was 57.7%, after adjusting for expenses related to our pending merger with Eurex.

Our tax rate increased to 46.5% from 44.1% in the second quarter of 2006 due to non-deductible merger related costs.

Net income for the second quarter increased to $15.9 million from $13.8 million in the prior year quarter.

Excluding costs related to the pending merger with Eurex, proforma pre-tax income in the options segment of our business increased to $31.9 million and net income increased to $18.0 million.

Year-to-Date Results

For the first six months of 2007, average daily volume of equity and index options increased to 2.8 million contracts traded as compared to 2.4 million equity and index options contracts traded in the prior year. Revenues in the options segment increased to $113.9 million from $98.7 million last year. Gross margin increased to $105.6 million from $86.7 million and year-to-date pre-tax margin was 56.1%. Net income increased to $32.6 million from $26.7 million and earnings per share on a fully diluted basis were $0.81 as compared to $0.68 last year.

(1) Represents single counted contract volume. For example, a
 transaction of 500 contracts on our exchange is counted as a single
 500 contract transaction for purposes of calculating our volumes,
 even though we may receive transaction fees from parties on both
 sides of the transaction, one side of a transaction, or in some
 cases, neither side of a transaction.

(2) Our market share is calculated based on the number of contracts
 executed on our exchange as a percentage of total industry contract
 volume.

(3) Represents each side of a buy or sell transaction. For example, a
 transaction of 500 contracts on our exchange is counted as two sides
 of 500 contracts, representing a buy and a sell transaction. We
 generally do not charge our members for executing non-broker-dealer
 customer orders on our exchange except for options on our premium
 products as well as options for listings in our Second Market.

(4) Represents our market share of total U.S. industry equity and
 index trading for members trading on our exchange based on contract
 trading volume.

(5) Average transaction fee per side is calculated by dividing our
 transaction fees by the total number of sides executed on our
 exchange. We generally do not charge our members for executing non-
 broker-dealer customer orders on our exchange except for options on
 our premium products as well as options for listings in our Second
 Market. Comparing our average transaction fee per side to our average
 transaction fee per revenue side reflects the negative effect of our
 fee waivers or reductions on our revenues, on a per side basis.

(6) Average cost of transaction fee per side is calculated by
 subtracting cost of revenues from transaction fees, which we refer to
 as net transaction fees, and dividing the result by the total number
 of sides executed on our exchange.

(7) Our average transaction fee per revenue side reflects the
 transaction fee we charge to our market participants per our publicly
 available pricing schedules. These schedules were part of rule
 proposals that became effective upon filing pursuant to Section
 19(b)(3)(A) of the Securities Exchange Act of 1934, as amended (the
 "Exchange Act"). The Securities and Exchange Commission may abrogate
 such rule proposals within 60 days of filing if it determines that
 such action is necessary or appropriate in the public interest, for
 the protection of investors or otherwise in furtherance of the
 purposes of the Exchange Act.

(8) Members can have several contracts per trade. Trades represent the
 number of trades cleared through The Option Clearing Corporation, or
 the OCC. Market data revenue is generated on a per trade basis, not
 on a contract basis.

(9) By "issues" we mean the number of securities underlying our
 options. We trade multiple options series on each underlying
 security.

(10) Excludes full-time equivalent employees of ISE Stock Exchange,
 LLC, beginning April 2006.
    Segment Information

    We operate two segments:

    --  An Options Exchange business segment which includes our
        options trading business as well as Alternative Markets
        platform, corporate overhead costs related to public company
        matters and corporate wide strategic initiatives.

    --  A Stock Exchange business segment which includes trading in
        equity securities. Pursuant to the terms of our agreement with
        the strategic investors of the ISE Stock Exchange and in
        accordance with U.S. GAAP, we are the primary beneficiary of
        the ISE Stock Exchange and consolidated its financial results.
        We exercise a majority of the voting interest of the ISE Stock
        Exchange; however, beginning April 2006 all losses have been
        allocated solely to the minority owners. Consolidation of the
        ISE Stock Exchange does not currently have any effect on our
        net results of operations and will not until it generates net
        profits. Therefore, consolidation increases our revenues and
        expenses to reflect 100% of the ISE Stock Exchange's results;
        however, these revenues and expenses are offset
        dollar-for-dollar by minority interest since we are not
        required to recognize any of its losses.

Non-GAAP Reconciliation

In an effort to provide additional information regarding our results as determined by GAAP, we also disclose certain non-GAAP information which we believe provides useful and meaningful information. Our management reviews this non-GAAP financial measurement when evaluating our financial performance and results of operations; therefore, we believe it is useful to provide information with respect to these non-GAAP measurements so as to share this perspective of management. Non-GAAP measurements do not have any standardized meaning and are therefore unlikely to be comparable to similar measures presented by other companies. These non-GAAP financial measures should be considered in the context with our GAAP results.

We have disclosed our net income amounts excluding certain non-operating charges. These non-operating charges relate to advisory expenses incurred in connection with our pending merger with Eurex. Management excludes these costs when measuring our financial performance as they do not relate to our core business of operating a multi-asset class exchange. Management believes presenting our results excluding these costs provides a clearer measure of our results and performance.

ISE's alternative markets business currently consists of an events market trading platform known as Longitude. Longitude's patented and proprietary technology provides a unique parimutuel structure for derivatives auctions which results in greater trading and pricing flexibility for market participants.
