NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying interim consolidated financial statements include the accounts of Arbinet-thexchange, Inc. (“Arbinet” or the “Company”) and its wholly-owned subsidiaries. All material intercompany accounts and transactions have been eliminated in consolidation. The accompanying interim consolidated financial statements of the Company have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), consistent in all material respects with those applied in the Company’s Annual Report on Form 10-K for the year ended December 31, 2006. Interim financial reporting does not include all of the information and footnotes required by GAAP for complete financial statements. The interim financial information is unaudited, but reflects all adjustments (consisting of normal, recurring adjustments) that are, in the opinion of management, necessary to provide a fair statement of results for the interim periods presented. Operating results for the three and six months ended June 30, 2007 are not necessarily indicative of the results that may be expected for the year ending December 31, 2007.

Reclassifications

Certain amounts in the comparative periods have been reclassified to conform to the current period’s presentation in the consolidated statements of operations and consolidated statements of cash flows. Amounts repaid under the SVB Non-Recourse Receivable Purchase Agreement are presented as “Payments to Silicon Valley Bank” in the accompanying statements of cash flows. Certain software and hardware maintenance costs were reclassified from “General and administrative” to “Operations and development” and “Sales and marketing”.

Effects of Recently Issued Accounting Pronouncements

FASB Statement No. 157: Fair Value Measurements

In September 2006, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”), which clarifies the definition of fair value, establishes a framework for measuring fair value and expands the disclosures on fair value measurements. SFAS 157 is effective for fiscal years beginning after November 15, 2007. We do not expect that SFAS 157 will have a significant impact on our consolidated results of operations, cash flows and financial position.

FASB Statement No. 159: The Fair Value Option for Financial Assets and Financial Liabilities

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS 159”), which allows measurement of specified financial instruments, warranty and insurance contracts at fair value on a contract-by-contract basis, with changes in fair value recognized in earnings in each period. SFAS 159 is effective as of the beginning of an entity’s first fiscal year beginning after November 15, 2007. We do not expect that SFAS 159 will have a significant impact on our consolidated results of operations, cash flows and financial position.

2. EARNINGS PER SHARE

Basic earnings per share are computed by dividing net income (loss) available for common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share are calculated based on the weighted average number of outstanding common shares plus the dilutive effect of stock options and warrants as if they were exercised. During a loss period, the effect of the potential exercise of stock options and warrants are not considered in the diluted earnings per share calculation since it would be antidilutive.

4

The following is a reconciliation of the basic weighted average number of common shares outstanding to diluted weighted average number of common and common share equivalent shares outstanding:

	June 30,
	2006	2007
Basic number of common shares outstanding	24,996,476	25,468,272
Dilutive effect of unvested restricted stock, restricted stock units, stock options and warrants	691,272	—
Dilutive number of common and common share equivalents	25,687,748	25,468,272

For the six months ended June 30, 2006 and June 30, 2007 outstanding stock options of 1,581,476 and 1,181,012, respectively, have been excluded from the above calculations because the effect on net income (loss) per share would have been antidilutive. For the six months ended June 30, 2006 and June 30, 2007 warrants of 6,250 and 1,439, respectively, have been excluded from the above calculations because the effect on net income per share would have been antidilutive.

3. INCOME TAXES

The Company recorded an income tax benefit of $1,882 and an income tax provision of $161,846 for the six months ended June 30, 2006 and 2007, respectively. The income tax provision in 2007 represents the statutory requirements for state taxes. The income tax benefit of $1,882 in 2006 was based upon the Company’s 2006 estimated effective annual tax rate of approximately (1)%. The difference between the federal statutory tax rate and the estimated effective tax rate in 2006 was primarily related to the expected utilization of certain of the Company’s net operating loss carryforwards and the impact of state taxes.

In 2006, FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes—an Interpretation of FASB Statement No. 109, Accounting for Income Taxes” (“FIN 48”). FIN 48 addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under FIN 48, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position should be measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. FIN 48 also provides guidance on derecognition, classification, interest and penalties on income taxes, accounting in interim periods and requires increased disclosures.

The Company adopted the provisions of FIN 48 effective January 1, 2007. As a result of the implementation of FIN 48, the Company identified an aggregate of $1,281,000 of unrecognized tax benefits, including related estimated interest and penalties, due to uncertain tax positions. Approximately $589,000 of these uncertain tax positions resulted in a reduction of deferred tax assets against which the Company had recorded a full tax valuation allowance on its balance sheet. The balance of the unrecognized tax benefits, amounting to $692,000, which includes interest and penalties, was recorded as an increase to accumulated deficit and an increase of $656,000 and $36,000 to “accrued and other current liabilities” and “other long-term liabilities”, respectively. While the Company believes that it has identified all reasonably identifiable exposures and that the reserve it has established for such exposures is appropriate under the circumstances, it is possible that additional exposures exist and that exposures will be settled at amounts different than the amounts reserved. It is also possible that changes in facts and circumstances could cause the Company to either materially increase or reduce the amount of our tax reserve.

As of January 1, 2007, after the implementation of FIN 48, the amount of unrecognized tax benefits is $1,160,000, of which, recognition of $692,000 would impact the Company’s effective tax rate. There were no material changes in this amount as of June 30, 2007.

The Company recognizes potential interest and penalties relating to income tax positions as a component of the provision for income taxes. As of January 1, 2007, the Company has recorded a liability for the payment of interest and penalties of $58,000 and $63,000, respectively.

5

The Company's U.S. subsidiaries join in the filing of a U.S. federal consolidated income tax return. The U.S. federal statute of limitations remains open for the years 2003 onward. The Company is no longer subject to federal, state or foreign income tax assessments for years prior to 2003. The Company is not currently under examination by the Internal Revenue Service. State income tax returns are generally subject to examination for a period of three to five years after filing of the respective return. The state impact of any federal changes remains subject to examination by various states for a period of up to one year after formal notification to the states. The Company is not currently under examination in any state jurisdictions. Foreign income tax returns are generally subject to examination for a period of three to six years after filing of the respective return. The Company is currently under examination in the United Kingdom for its 2004 and 2005 tax years.

Within the next twelve months, the Company expects to complete a formal study of changes in its ownership since the prior testing date which occurred in 2004. The Company’s total amount of unrecognized tax benefits may change. Depending on the outcome of this study, an estimate of the range of this reasonably possible change is from a decrease in the liability of $546,000 to no change. In the event that the Company’s income tax examination in the United Kingdom concludes within the next twelve months, the Company’s total amounts of unrecognized tax benefits, excluding related estimated interest and penalties, may change. Depending on the outcome of this examination, an estimate of the range of this reasonably possible change is from an increase of $408,000 to a decrease of $612,000 in deferred tax assets. The Company had recorded a full tax valuation allowance on its balance sheet and this item will have no impact on the statement of operations.

4. STOCKHOLDERS’ EQUITY

The table below summarizes the issued share activity for the Company’s common stock since December 31, 2006. Treasury shares held by the Company are included in these balances:

Balance as of December 31, 2006	25,851,493
Retirement of restricted stock	(31,308	)
Exercise of options	7,043
Balance as of June 30, 2007	25,827,228

On June 11, 2007, the Board of Directors of Arbinet authorized the repurchase of up to $15 million of the Company’s common stock at any time and from time to time (the “Repurchase Plan”). The share repurchases may be made at management’s discretion in the open market in compliance with applicable securities laws and other legal requirements and are subject to market conditions, share price, and other factors. The Repurchase Plan may be suspended or discontinued at any time. Shares of the Company’s common stock repurchased under the Repurchase Plan will be held in the Company’s treasury. As of June 30, 2007, the Company has repurchased 140,549 shares of its stock for $816,062.

5. RESTRUCTURING AND SEVERANCE CHARGES

Restructuring:During 2001 and 2002, the Company exited two separate facilities and accordingly recorded charges for the future lease obligations, net of estimated sub-lease income. The table below shows the amount of the charges and the cash payments related to those liabilities.

	($ in thousands)
Balance as of December 31, 2006	$	1,724
Cash payments		(245	)
Balance as of June 30, 2007	$	1,479

As of June 30, 2007, $0.5 million of the $1.5 million balance is recorded in accrued and other current liabilities and $1.0 million is recorded in other long-term liabilities.

Severance Charges: In June 2007, the Company recorded severance charges related to a resignation agreement entered into with our former Chief Executive Officer and a workforce reduction of certain employees in our Voice and Data Services segment. In accordance with SFAS No. 112 (“SFAS 112”), “Employers’ Accounting for Post-employment Benefits”, an amendment of FASB Statements No. 5 and 43, benefits were provided pursuant to a severance plan which used

6

a standard formula of paying benefits based upon tenure with the Company. The accounting for these severance costs has met the four requirements of SFAS 112 which are: (i) the Company’s obligation relating to employees’ rights to receive compensation for future absences is attributable to employees’ services already rendered; (ii) the obligation relates to rights that vest or accumulate; (iii) payment of the compensation is probable; and (iv) the amount can be reasonably estimated. All severance related obligations related to these charges will be paid by the end of the third quarter of 2007.

6. PROPERTY AND EQUIPMENT

During the quarter ended June 30, 2007 (the determination date), the Company decommissioned certain fixed assets located at its Exchange Delivery Point in London. Management is committed to selling this equipment and expects to recover the carrying amount, which is approximately $183,000 as of June 30, 2007. The Company believes these assets will be sold no later than the end of the second quarter of fiscal 2008. On the determination date, the Company determined that the plan of sale criteria in SFAS No, 144, “Accounting for the Impairment or Disposal of Long-Lived Assets,” had been met. The carrying value of this equipment that is held for sale is included in “prepaids and other current assets” as of June 30, 2007. The carrying amount of this equipment as of December 31, 2006 was approximately $397,000, which is included in “property and equipment, net”. Also included in “prepaids and other current assets” as of June 30, 2007 are approximately $128,000 of previously decommissioned fixed assets located at the Company’s Exchange Delivery Point in New York.

7. GOODWILL AND INTANGIBLES, NET

The balance of goodwill was $2,182,680 and $2,603,833 at December 31, 2006 and June 30, 2007, respectively. During the quarter ended March 31, 2007, in accordance with SFAS No. 141, “Business Combinations”, the Company completed the allocation of purchase price related to the acquisition of all of the outstanding common stock of Flowphonics Limited, now known as Broad Street Digital Limited (the “Broad Street Digital Acquisition”). The reallocation resulted in an increase in goodwill of $330,000 and a corresponding reduction in the amount allocated to identifiable intangible assets.

As of June 30, 2007, amounts attributable to the Digital Media segment were $385,000 of goodwill and $1,573,000 of intangible assets, net. The balance of the goodwill and intangible assets, net, are attributable to the Voice and Data Services segment.

8. SEGMENT REPORTING

In fiscal year 2007, we have two reportable segments, Voice and Data Services which is an electronic market for trading, routing and settling communications capacity and Digital Media which currently operates a license management platform for intellectual property rights and digital content distribution. In fiscal 2006, the Company operated in one business segment. We identified our segments in accordance with the provisions of SFAS No. 131, “Disclosures about Segments of an Enterprise and Related Information”, as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our Interim Chief Executive Officer or Chief Executive Officer. Our Company's reportable segments are strategic business units that offer different products and services. They are managed separately because each business requires different technology and marketing strategies.

We evaluate the performance of each reportable segment based on fee revenues and income (loss) from operations. Asset balances by reportable segment have not been included in the segment table below, as these are managed on a company-wide level and are not allocated to each segment for management reporting purposes.

9. COMMITMENTS AND CONTINGENCIES

Legal Proceedings

The litigation process is inherently uncertain, and we cannot guarantee that the outcomes of the following proceedings and lawsuits will be favorable for us or that they will not be material to our business, results of operations or financial position. However, the Company does not currently believe that these matters will have a material adverse effect on our business, results of operations or financial position.

World Access Proceeding

On March 18, 2003, World Access, Inc. f/k/a WAXS, Inc., WA Telcom Products Co., Inc., WorldxChange Communications, Inc., Facilicom International LLC and World Access Telecommunications Group, Inc. f/k/a Cherry Communications Incorporated d/b/a Resurgens Communications Group (collectively “the Debtors”), filed a lawsuit against us in the United States Bankruptcy Court for the Northern District of Illinois, Eastern Division. The Debtors had previously filed for bankruptcy under Chapter 11 of the United States Bankruptcy Code. The Debtors seek recovery of certain payments they made to us as a buyer on our exchange, which total approximately $855,000. The Debtors claim that such payments were preferential transfers under the Bankruptcy Code. The Debtors also seek costs and expenses, including attorneys’ fees and interest. We filed an answer to the complaint on April 18, 2003, denying the Debtors’ claims for relief and asserting several affirmative defenses. On August 12, 2003, we served discovery on the attorneys for World Access and its related entities. Shortly after we served our discovery, the bankruptcy judge entered an order stating that the cases of World Access and its related entities, which had been jointly administered, could not be substantively consolidated. Since then the majority of Debtors’ preference complaints in the case have been continued. In September 2004, the Debtors confirmed a Plan of Liquidation that created a trust to proceed with liquidating avoidance actions. The Trustee has been substituted as the Plaintiff in all avoidance actions. At a scheduling conference held on October 12, 2005, the Court set discovery cut-off dates that have been continued for cases where the Trustee seeks to recover in excess of $100,000, at the request of the Trustee. Plaintiff’s responses to certain discovery requests were due in November. The current discovery schedule designates August 13, 2007 as the deadline for all discovery. Based on the revised discovery plan and a statement from the Court at the scheduling conference, it does not appear that the Court will be ready to try any of the adversary proceedings before the fourth quarter of 2007.

Octane Proceeding

On May 27, 2003, we received a demand letter from counsel for Octane Capital Management and its affiliate, Octane Capital Fund I, L.P. (collectively “Octane”), demanding the right to purchase up to $2.8 million of our shares of Series E preferred stock on the same terms as originally set forth in a Securities Purchase Agreement dated as of July 3, 2001. Additionally, the letter demanded the right to convert Octane’s investment in shares of our Series D preferred stock into shares of Series D-1 preferred stock pursuant to the terms of such purchase agreement.

8

The Octane demand letter also alleged violations of Octane’s rights under a Second Amended and Restated Investors’ Rights Agreement dated as of March 7, 2000 (the “Investors’ Rights Agreement”), including, among other allegations, the allegation that Octane did not receive proper advance notice of the complete terms of our Series E preferred stock offering. Arbinet denies all of the allegations. On May 28, 2003, we sent notice to all stockholders, including Octane, indicating our plan to defend against these claims.

On September 1, 2004, after no contact with us for over a year, Octane contacted our representatives to renew its demand against us. We responded to Octane’s demand, denying all allegations of wrongdoing.

On December 10, 2004, we received a complaint filed that day by Octane and Amerindo Technology Growth Fund II Inc. (“ATGF”), another investor of the Company, in the United States District Court for the Southern District of New York, entitled Octane Capital Fund, L.L.P. et al. v. Arbinet-thexchange, Inc., Civil Action No. 04-CV-9759 (KMW). Octane and ATGF filed an amended complaint with the court on December 13, 2004, amending and replacing the December 10, 2004 complaint. The amended complaint alleged, among other things, that we breached terms of the Investors’ Rights Agreement by failing to give Octane and ATGF proper advance notice of the complete terms of our Series E preferred stock offering. The amended complaint sought money damages for both Octane and ATGF for the alleged breach of contract. On February 11, 2005, we filed our answer to the amended complaint, denying all liability, and filed counterclaims against Octane and ATGF for, among other claims, breach of the Investors’ Rights Agreement in connection with their conduct seeking additional shares of stock and other relief.

On May 9, 2005, the plaintiffs filed an unopposed motion to dismiss this case in federal court without prejudice for lack of subject matter jurisdiction. The court granted the plaintiffs’ motion on the same day. On November 4, 2005, Octane renewed the lawsuit by filing a substantially similar complaint in the Superior Court of New Jersey, Middlesex County, in an action entitled Octane Capital Fund I, L.P. v. Arbinet-thexchange, Inc., Docket No. MID-L-7990-05. Octane is the only plaintiff in the case. On October 3, 2006, we filed an answer denying all liability and asserting counterclaims against Octane for, among other reasons, breach of the Investors’ Rights Agreement in connection with Octane’s conduct seeking additional shares of stock and other relief. Octane filed its answer on October 27, 2006, denying all liability on our counterclaims.

On July 12, 2007, the parties entered into a Settlement Agreement and Release the impact of which has been recorded in the “Provision for Litigation” as of June 30, 2007. A voluntarily dismissal with prejudice was entered on July 24, 2007.

Mashinsky Series E Proceeding

On May 13, 2005, we received a letter from counsel representing Alex Mashinsky, our founder, former officer and a current director, together with a draft complaint and a draft press release, threatening to commence litigation in the Southern District of New York against us, as well as against Communications Ventures III, L.P., one of our stockholders, former director Anthony L. Craig, former director Roland A. Van der Meer, and our former President, Chief Executive Officer and director, J. Curt Hockemeier, if we do not agree to an “amicable settlement” with him. Mr. Mashinsky alleges breach of fiduciary duty, self-dealing, fraud, and breach of contract in connection with our Series E preferred stock offering consummated in 2001, asserting over $90 million in damages. According to his correspondence he “is prepared to discuss settlement of this matter at an amount representing a significant discount.” By letter dated May 31, 2005, the Company and other potential defendants responded to Mr. Mashinsky’s letter, denying any liability and describing potential counterclaims that would be asserted against Mr. Mashinsky should he pursue his claims.

On July 13, 2007, the Company entered into an agreement with Mr. Mashinsky in which he agreed, among other things, to release the Company from any claims relating to the Series E preferred stock offering, including, but not limited to, the allegations outlined in the May 13, 2005 letter. The impact of this agreement has been recorded in the “Provision for Litigation” as of June 30, 2007.

World-Link Proceeding

On December 15, 2005, Arbinet filed a patent infringement lawsuit against World-Link Telecom, Inc. in the U. S. District Court in the Eastern District of New York. Arbinet asserts that World-Link has infringed three of its U.S. patents relating to the trading of telecommunications capacity, namely, U.S. Patent Nos. 6,226,365; 6,442,258; and 6,542,588. By its Complaint, Arbinet seeks damages and injunctive relief.

World-Link filed its Answer and Counterclaims to the Complaint on January 23, 2006. By its Answer, World-Link denied Arbinet’s infringement allegations and asserted that the claims of the patents in suit are invalid. World-Link also

9

asserted a counterclaim for declaratory judgment that it did not infringe the patents in suit and that the patents in suit were invalid, and counterclaims for tortuous interference with contractual relations and monopolization or attempted monopolization under Section 2 of the Sherman Act.

On February 8, 2006, the parties attended an initial conference with the Magistrate Judge assigned to the case for the purposes of setting a schedule for the case. No case schedule has been issued yet. Discovery has begun in the case. The parties negotiated and the court entered a Protective Order to govern the treatment of the confidential and proprietary information of the parties during the case. On March 30, 2006, we served a set of discovery requests on counsel for World-Link. Shortly thereafter, World-Link served discovery requests on our counsel. World-Link responded to our discovery requests and produced documents to us on June 1, 2006. We responded to World-Link’s discovery requests on June 8, 2006 and produced documents to World-Link subsequently. On September 22, 2006, the Court issued an order referring the case to mediation. The parties exchanged settlement proposals during mediation and the mediation ended without an agreement. The parties exchanged proposed construction of patent claim terms on March 8, 2007, and were scheduled to serve opening briefs on claim construction on March 29, 2007. However, prior to the March 29 deadline, World-Link filed a motion for a proposed consent judgment, which proposal does not require an admission of infringement. Since such consent judgment would be meaningless, as it will allow World-Link to continue its infringing acts, Arbinet filed an opposition to this motion. On March 15, 2007, World-Link’s lead counsel filed a motion to withdraw as counsel citing Arbinet’s allegation of willful infringement, despite Arbinet’s offer to accommodate (and even though Arbinet’s original filed complaint alleges willful infringement). On March 21, 2007, World-Link filed a motion to stay discovery on the ground that the proposed consent judgment rendered further discovery unnecessary. Arbinet opposed the motion to stay discovery, as it needs to uncover certain facts surrounding World-Link’s infringement and the willfulness of such tortuous act. On April 3, 2007, Arbinet filed a motion to add other World-Link affiliates as defendants in this action. On the morning of April 5, 2007, the day of the scheduled status conference, World-Link submitted a letter stating that it has filed a voluntary petition under Chapter 11 of the Bankruptcy Code. At the April 5 status conference, World-Link’s bankruptcy counsel represented that the action is automatically stayed. Arbinet promptly served a new complaint on the World-Link affiliates later that day. On April 13, 2007, Arbinet submitted a letter to the Court contending that the bankruptcy proceeding initiated by World-Link does not automatically stay, among other things, Arbinet’s motion to add non-bankrupt World-Link affiliates in the pending World-Link action. On April 27, 2007, Arbinet filed, in the US Bankruptcy Court, District of New Jersey, where World-Link Telecom’s bankruptcy petition is pending, (i) a motion for an order determining that Section 362(a) of the Bankruptcy Code does not preclude the continued prosecution of an action for injunctive relief against post-petition patent infringement, and (ii) a motion for relief from stay, to the extent necessary, to allow the remainder of the action to proceed. On April 30, 2007, World-Link Telecom filed in the bankruptcy court a motion for an entry of an order authorizing World-Link Telecom to enter into a common interest agreement with its affiliated entities in defense of Arbinet’s patent infringement claims.

The parties have recently engaged in discussions to resolve this matter and have agreed to submit this matter to mediation if such discussions are unsuccessful.

CHVP Proceeding

On April 6, 2006, CHVP Founders Fund I, L.P. (“CHVP”) filed a lawsuit against us in the Supreme Court of the State of New York, County of New York. CHVP seeks damages of over $1.87 million related to the transfer, by our founder and current director, Alex Mashinsky, of three million shares of our common stock to CHVP. CHVP had previously been sued by Mr. Mashinsky regarding the same transfer of shares. CHVP claims that we interfered with its ability to sell the shares during a 90-day period from December 2004 to March 2005, and alleges claims for violation of the Uniform Commercial Code, conversion, and breach of contract. On May 22, 2006, we filed our Answer and Counterclaim denying liability, and asserting counterclaims against CHVP for a declaratory judgment that the transfer of Mr. Mashinsky’s shares to CHVP is void or voidable, that Arbinet did not improperly interfere with CHVP’s sale of Arbinet stock during the lock up period, and that Mr. Mashinsky’s shares were subject to a particular market stand-off restriction pursuant to operative agreements. In addition, we filed a Third Party Complaint against Mr. Mashinsky requesting the same declaratory judgment described above, and asserted claims for breach of contract, breach of implied covenant of good faith and fair dealing, negligence, indemnification, and common law contribution in connection with Mr. Mashinsky’s transfer of Arbinet shares to CHVP. As of May 11, 2007, the matter was settled between the parties the impact of which has been recorded in the “Provision for Litigation” as of June 30, 2007.

The action was dismissed with prejudice on May 29, 2007.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

We are a leading electronic market for trading, routing and settling communications capacity. Members of our exchange, consisting primarily of communications services providers, buy and sell voice calls and Internet capacity through our centralized, efficient and liquid marketplace. Communications services providers that do not use our exchange generally individually negotiate and buy access to the networks of other communications services providers to send voice calls and Internet capacity outside of their networks. We believe that we provide a cost-effective and efficient alternative to these direct connections. With a single interconnection to our exchange, members have access to all other members’ networks. Members place orders through our easy-to-use web-based interface. Sellers on the exchange post sell orders to offer voice calls and Internet capacity for specific destinations, or routes, at various prices. We independently assess the quality of these routes and include that information in the sell order. Buyers enter buy orders based on route quality and price and are matched to sell orders by our fully automated trading platform and our proprietary software. When a buyer’s order is matched to a seller’s order, the voice calls or Internet capacity are then routed through our state-of-the-art facilities. We invoice and process payments for our members’ transactions and manage the credit risk of buyers primarily through our credit management programs with third parties.

Revenue

We generate revenues from both the trading that members conduct on our exchange, which we refer to as trading revenues, and the fees we charge members for the ability to trade on our exchange, which we refer to as fee revenues. Our trading revenue represents the aggregate dollar value of the calls that are routed through our switches at prices agreed to by the buyer and seller of the capacity. For example, if a 10-minute call is originated in France and routed through our facilities to a destination in India for $0.11 per minute, we record $1.10 of trading revenue for the call. Under our AssuredAxcess product, we offer our members the ability to buy and sell minutes to specific markets at fixed rates. We may incur losses associated with this trading revenue. Historically, these losses have not been material to our operating results. Our system automatically records all traffic terminated through our switches.

We record trading revenues principally because:

• all traffic traded on our exchange is routed through one of our switches; and

• we are obligated to pay sellers for the minutes they sell on our exchange regardless of whether we ultimately collect from buyers.

Our fee revenues represent the following:

• usage fees for the number of minutes or megabytes that are routed through our switches and price improvement, which represents cost savings generated by our trading platform, which collectively comprised approximately 75% and 80% of fee revenues for the six months ended June 30, 2006 and 2007, respectively;

• a credit risk management fee, which is a charge for the credit management, clearing and settlement services we provide;

• a membership fee to join our exchange; and

• fees for additional services as utilized by our members for items such as premium service offerings and accelerated payment terms.

11

Costs and Expenses

Our cost of trading revenues consists of the cost of calls, which are routed through our switches at the price agreed to by both the buyer and seller of the capacity. Using the example above in the caption “Revenues”, we would record cost of trading revenues equal to $1.10, an amount that we would pay to the seller.

Operations and development expense consists of costs related to supporting our exchange, such as salaries, benefits, and related costs of engineering, technical support, product and software development and system support personnel, as well as facilities and interconnect costs. Sales and marketing consists of salaries, benefits, commissions, and related costs of sales and marketing personnel, trade shows and other marketing activities. General and administrative costs consist of salaries, benefits, and related costs of corporate, finance and administrative personnel, facilities costs, bad debt expense and outside service costs, such as legal and accounting fees.

Strategic Alternatives

On October 23, 2006, we announced that our Board of Directors formed a special committee of independent directors (the “Special Committee”) to explore a broad range of strategic alternatives to enhance shareholder value. These alternatives included, but were not limited to, a revised business plan, operating partnerships, joint ventures, strategic alliances, a recapitalization, and the sale or merger of the Company. Until Mr. Moore’s appointment as Interim Chief Executive Officer and President, the Special Committee was composed of Robert C. Atkinson, Michael J. Donahue, Roger H. Moore and Michael J. Ruane, each an independent director of Arbinet. Mr. Donahue serves as the Chairman of the Special Committee. The Special Committee retained Jefferies & Company, Inc. as its financial advisors and Goodwin Procter LLP as its legal counsel to assist it in its work. Mr. Moore resigned from the Special Committee on June 11, 2007 in connection with his appointment as Interim Chief Executive Officer and President.

On June 11, 2007, we announced that our Special Committee had completed its review of strategic alternatives. After an extensive analysis of a broad range of alternatives, the Board determined that the best alternative to maximize shareholder value in the near-term is to return cash to shareholders through a stock repurchase plan of up to $15 million. The Board will continue to evaluate additional options for capital allocation, including a possible expansion of the stock repurchase plan, as well as initiatives to strengthen the Company’s business.

Digital Media

In August 2006, we established a new subsidiary, Arbinet Digital Media Corporation, to explore and develop products and services to address the large and growing market opportunity presented by the exchange of digital media. In December 2006, the Company, through its wholly-owned subsidiary, Arbinet ETE Corporation, acquired all of the outstanding common stock of Flowphonics Limited, now known as Broad Street Digital Limited, a license management platform for intellectual property rights and digital content distribution. The purchase price was approximately $2.1 million, including transaction costs. Broad Street Digital’s rightsrouter platform enables music and video rights owners to manage, exchange, distribute, and receive payment for their content with many of the world’s major online and mobile retailers. This acquisition allows us to combine our exchange platform and business processes with Broad Street Digital’s patent-protected license management and digital content distribution platform to address the growing market for the management, exchange, distribution and settlement of digital media.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of our operations are based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires management to make estimates and judgments that affect the amounts reported for assets, liabilities, revenues, expenses and the disclosure of contingent liabilities. Our significant accounting policies are more fully described in Note 1 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2006.

Our critical accounting policies are those that we believe are both important to the portrayal of our financial condition and results of operations and often involve difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. Management evaluates these estimates, including those

12

related to bad debts, income taxes, long-lived assets, restructuring, contingencies and litigation on an ongoing basis. The estimates are based on historical experience and on various assumptions about the ultimate outcome of future events. Our actual results may differ from these estimates because we did not estimate correctly.

We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our consolidated financial statements:

Long-lived assets. We assess the impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying value may not be recoverable, in accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS 144”). Factors we consider important which could trigger an impairment review include the following:

• significant underperformance relative to expected historical or projected future operating results;

• significant changes in the manner of or use of the acquired assets or the strategy for our overall business; and

• significant industry, economic or competitive trends.

Income taxes. We have net deferred tax assets, reflecting net operating loss, or NOL, carryforwards and other deductible differences, which may reduce our taxable income in future years. These net deferred tax assets are offset by a valuation allowance resulting in no tax benefit being recognized related to these net deferred tax assets. We are required to periodically assess the realization of our deferred tax assets and changes in circumstances may require adjustments in future periods. The amount of net deferred tax assets actually realized could vary if there are differences in the timing or amount of future reversals of existing deferred tax liabilities or changes in the amounts of future taxable income. If it becomes more likely than not that we will recognize a future tax benefit from the deferred tax assets, we may need to reverse some or all of our valuation allowance. When evaluating the ability for the Company to record a net deferred tax asset, SFAS No. 109, “Accounting for Income Taxes,” requires us to consider all sources of taxable income as well as all available evidence to determine that it is more likely than not that we will be able to utilize this asset. At December 31, 2006 a full valuation allowance in the amount of $39.7 million has been recorded against net deferred tax assets since at that date, the Company was unable to conclude that it was more likely than not that it would realize those assets. We will continue to refine and monitor all available evidence during future periods in order to more fully evaluate the recoverability of the Company’s deferred tax assets.

On January 1, 2007 we adopted FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes—an Interpretation of FASB Statement No. 109, Accounting for Income Taxes” (“FIN 48”) to account for uncertain tax positions. FIN 48 requires that we recognize in our financial statements the impact of a tax position, if that position is more likely than not of being sustained on audit, based on the technical merits of the position. Included in the Company’s Consolidated Balance Sheet at June 30, 2007 is approximately $0.7 million of accrued and other current liabilities associated with uncertain tax positions in the various jurisdictions in which we conduct business.

The application of income tax law is inherently complex. Tax laws and regulations are voluminous and at times ambiguous, and interpretations of and guidance regarding income tax laws and regulations change over time. This requires us to make many subjective assumptions and judgments regarding our income tax exposures. Changes in our assumptions and judgments can materially affect our financial position, results of operations and cash flows.

Allowance for doubtful accounts. We maintain an allowance for doubtful accounts for estimated losses resulting from the failure of members on our exchange to make required payments. The amount of our allowance is based on our historical experience and an analysis of our outstanding accounts receivable balances. If the financial condition of our members deteriorates, resulting in additional risk in their ability to make payments to us, then additional allowances may be required, which would result in an additional expense in the period that this determination is made. While credit losses have historically been within our range of expectations and our reserves, we cannot guarantee that we will continue to experience the same level of doubtful accounts that we have in the past.

Goodwill and Other Intangible Assets. We follow the guidance of SFAS No. 142. “Goodwill and Other Intangible Assets,” which requires that purchased goodwill and certain indefinite-lived intangibles no longer be amortized but instead goodwill is subject to an annual assessment for impairment by applying a fair value approach. In assessing the recoverability of our goodwill and other intangibles, we must make assumptions regarding estimated future cash flows. If such assumptions change in the future, we may be required to record impairment charges for these assets.

13

Litigation reserves. The establishment of litigation reserves requires judgments concerning the ultimate outcome of pending litigation against the Company and its subsidiaries. These reserves are based on the application of SFAS No. 5, “Accounting for Contingencies,” (“SFAS 5”) which requires us to record a reserve if we believe an adverse outcome is probable and the amount of the probable loss is capable of reasonable estimation. In applying judgment, management utilizes, among other things, opinions and estimates obtained from outside legal counsel to apply the standards of SFAS 5. Accordingly, estimated amounts relating to certain litigation have met the criteria for the recognition of a liability under SFAS 5. Litigation by its nature is uncertain and the determination of whether any particular case involves a probable loss or the amount thereof requires the exercise of considerable judgment, which is applied as of a certain date. The required reserves may change in the future due to new matters, developments in existing matters or if we determine to change our strategy with respect to any particular matter.

Results of Operations

Comparison of Six months Ended June 30, 2006 and 2007

Trading revenues and cost of trading revenues

Trading revenues increased 7.8% from $233.4 million for the six months ended June 30, 2006 to $251.6 million for the six months ended June 30, 2007. The increase in trading revenues was due to an increase in the volume traded by our members principally due to an increase in the number of members on our exchange from 446 on June 30, 2006 to 908 on June 30, 2007. This increase in volume was partially offset by a lower average trade rate per minute. A total of 7.1 billion minutes were bought and sold on Arbinet’s exchange in the six months ended June 30, 2007, an increase of 19% from the 6.0 billion minutes for the six months ended June 30, 2006. This increase was due to 907.2 million completed calls in the six months ended June 30, 2007, representing a 33% increase over the 679.6 million completed calls for the six months ended June 30, 2006. These gains were partially offset by a decrease in the average call duration from 4.4 minutes per call on our exchange for the six months ended June 30, 2006 to 3.9 minutes per call for the six months ended June 30, 2007. The lower average call duration was primarily a result of a change in the mix of geographic markets and the mix of fixed versus mobile minutes traded on our exchange. The volatility in average call duration and mix of geographic markets is expected to continue in the future.

As a result of increases in trading revenues, cost of trading revenues increased 7.9% from $233.3 million for the six months ended June 30, 2006 to $251.8 million for the six months ended June 30, 2007.

Fee revenues

Fee revenues increased 8.6% from $23.2 million for the six months ended June 30, 2006 to $25.2 million for the six months ended June 30, 2007. Fee revenues increased as a result of a 19% increase in minutes traded on the exchange offset, in part, by lower pricing. Average fee revenue per minute was $0.0035 in the six months ended June 30, 2007 compared to $0.0039 in the six months ended June 30, 2006. Average fee revenue per minute declined principally due to the mix of minutes traded on the exchange. We may provide incentives to increase member trading on our exchange which, combined with changes in the mix of minutes traded, may lead to a decline in average fee revenue per minute in the future. Fee revenues from our Digital Media segment for the six months ended June 30, 2007 were not material.

Operations and development

Operations and development costs increased 20.9% from $8.7 million for the six months ended June 30, 2006 to $10.5 million for the six months ended June 30, 2007. This increase was principally the result of increased compensation-related expenses of $1.1 million. The increase in compensation-related expenses is principally the result of increased headcount to support our businesses. Operations and development expenses for the six months ended June 30, 2007 include $0.7 million from our Digital Media segment.

14

Sales and marketing

Sales and marketing expenses increased 24.3% from $3.8 million for the six months ended June 30, 2006 to $4.7 million for the six months ended June 30, 2007. This increase was principally the result of increased compensation-related expenses of $0.5 million; higher consulting fees of $0.1 million; and higher marketing-related expenses of $0.2 million. Sales and marketing expenses for the six months ended June 30, 2007 include $0.6 million from our Digital Media segment.

General and administrative

General and administrative expenses were $8.3 million for the six months ended June 30, 2006 and $8.5 million for the six months ended June 30, 2007 as decreased legal fees of $0.9 million were offset by higher compensation-related expenses of $0.5 million; increased consulting and accounting fees of $0.4 million and higher bad debt expense of $0.2 million. General and administrative expenses for the six months ended June 30, 2007 related to our Digital Media segment were not material.

Depreciation and amortization

Depreciation and amortization increased from $3.5 million for the six months ended June 30, 2006 to $4.2 million for the six months ended June 30, 2007. This increase was the result of depreciation expense relating to capital expenditures during 2007, 2006 and 2005 and amortization expense associated with the intangible assets related to the acquisition of Broad Street Digital Limited in December 2006. Depreciation and amortization expense for the six months ended June 30, 2007 include $0.2 million from our Digital Media segment.

Severance charges

During the six months ended June 30, 2007, we recognized a charge of approximately $1.0 million, representing severance charges related to a resignation agreement entered into with our former Chief Executive Officer and to a workforce reduction of certain employees in our Voice and Data segment.

Provision for Litigation

During the six months ended June 30, 2007, we recognized a charge of $1.9 million representing management’s estimate of potential loss exposure in certain litigation matters. During June 2006, we settled certain litigation for $93 thousand less than the amount previously accrued.

Interest and other income/expense

Interest income increased from $1.4 million for the six months ended June 30, 2006 to $1.5 million for the six months ended June 30, 2007. This increase was primarily due to a higher average rate of return on invested cash and marketable securities partially offset by lower average balances in 2007 versus 2006. Other income (expense), net includes late fees charged by the Company to its members, net gains resulting from foreign currency transactions and fees paid by the Company under its third-party credit arrangements.

Provision for income taxes/income tax benefit

The Company recorded an income tax benefit of $2 thousand and an income tax provision of $200 thousand for the six months ended June 30, 2006 and 2007, respectively. The income tax provision in 2007 represents the statutory requirements for state taxes. The income tax benefit of $2 thousand in 2006 was based upon the Company’s 2006 estimated effective annual tax rate of approximately (1)%. The difference between the federal statutory tax rate and the estimated effective tax rate in 2006 was primarily related to the expected utilization of certain of the Company’s net operating loss carryforwards and the impact of state taxes.

15

Discontinued operations

Management reevaluated the liability related to a discontinued operation from 1999 and determined that approximately $225 thousand was needed at June 30, 2006. Accordingly, $121 thousand, net of income tax of $4 thousand, was recognized as income from discontinued operations in the six months ended June 30, 2006.

Comparison of Three Months Ended June 30, 2006 and 2007

Trading revenues and cost of trading revenues

Trading revenues increased 5.5% from $115.8 million for the three months ended June 30, 2006 to $122.1 million for the three months ended June 30, 2007. The increase in trading revenues was due to an increase in the volume traded by our members principally due to an increase in the number of members on our exchange from 446 on June 30, 2006 to 908 on June 30, 2007. This increase in volume was partially offset by a lower average trade rate per minute. A total of 3.48 billion minutes were bought and sold on Arbinet’s exchange in the three months ended June 30, 2007, an increase of 17% from the 2.99 billion minutes for the three months ended June 30, 2006. This increase was due to 465.4 million completed calls in the three months ended June 30, 2007, representing a 39.6% increase over the 333.5 million completed calls for the three months ended June 30, 2006. These gains were partially offset by a decrease in the average call duration from 4.5 minutes per call on our exchange for the three months ended June 30, 2006 to 3.7 minutes per call for the three months ended June 30, 2007. The lower average call duration was primarily a result of a change in the mix of geographic markets and the mix of fixed versus mobile minutes traded on our exchange. The volatility in average call duration and mix of geographic markets is expected to continue in the future.

As a result of increases in trading revenues, cost of trading revenues increased 5.6% from $115.8 million for the three months ended June 30, 2006 to $122.2 million for the three months ended June 30, 2007.

Fee revenues

Fee revenues increased 9.1% from $11.5 million for the three months ended June 30, 2006 to $12.5 million for the three months ended June 30, 2007. Fee revenues increased as a result of a 17% increase in minutes traded on the exchange offset, in part, by lower pricing. Average fee revenue per minute was $0.0036 in the three months ended June 30, 2007 compared to $0.0038 in the three months ended June 30, 2006. Average fee revenue per minute declined principally due to the mix of minutes traded on the exchange. We may provide incentives to increase member trading on our exchange which combined with changes in the mix of minutes traded, may lead to a decline in average fee revenue per minute in the future. Fee revenues from our Digital Media segment for the three months ended June 30, 2007 were not material.

Operations and development

Operations and development costs increased 22.3% from $4.4 million for the three months ended June 30, 2006 to $5.4 million for the three months ended June 30, 2007. This increase was principally the result of increased compensation-related expenses of $0.6 million. Most of the increase in compensation-related expenses is the result of increased headcount to support our businesses. Operations and development expenses for the three months ended June 30, 2007 include $0.4 million from our Digital Media segment.

Sales and marketing

Sales and marketing expenses increased 21.8% from $2.0 million for the three months ended June 30, 2006 to $2.4 million for the three months ended June 30, 2007. This increase was principally the result of increased compensation-related expenses of $0.3 million and higher marketing-related expenses of $0.1 million. Sales and marketing expenses for the three months ended June 30, 2007 include $0.3 million from our Digital Media segment.

General and administrative

General and administrative expenses decreased 21.4% from $5.1 million for the three months ended June 30, 2006 to $4.0 million for the three months ended June 30, 2007. This decrease was principally attributable to a decrease in legal

16

fees of $1.7 million. Legal fees in the three months ended June 30, 2006 included amounts related to the proxy contest in connection with the election of two Class II Directors at our 2006 Annual Meeting of Stockholders. This decrease was partially offset by higher compensation-related expenses of $0.2 million; higher consulting and accounting fees of $0.2 million and higher bad debt expense of $0.2 million. General and administrative expenses for the three months ended June 30, 2007 related to our Digital Media segment were not material.

Depreciation and amortization

Depreciation and amortization increased from $1.7 million for the three months ended June 30, 2006 to $2.0 million for the three months ended June 30, 2007. This increase was the result of depreciation expense relating to capital expenditures during 2007 and 2006 and amortization expense associated with the intangible assets related to the acquisition of Broad Street Digital Limited in December 2006. Depreciation and amortization expense for the three months ended June 30, 2007 include $0.1 million from our Digital Media segment.

Severance charges

During the three months ended June 30, 2007, we recognized a charge of approximately $1.0 million, representing severance charges related to a resignation agreement entered into with our former Chief Executive Officer and to a workforce reduction of certain employees in our Voice and Data segment.

Provision for Litigation

During the three months ended June 30, 2007, we recognized a charge of $790 thousand representing management’s estimate of potential loss exposure in certain litigation matters. During June 2006, we settled certain litigation for $93 thousand less than the amount previously accrued.

Interest and other income/expense

Interest income decreased from $0.8 million for the three months ended June 30, 2006 to $0.7 million for the three months ended June 30, 2007. This increase was primarily due to lower average balances in 2007 versus 2006 partially offset by a higher average rate of return on invested cash and marketable securities. Other income (expense), net includes late fees charged by the Company to its members, net gains resulting from foreign currency transactions and fees paid by the Company under its third-party credit arrangements.

Provision for income taxes/income tax benefit

The Company recorded an income tax benefit of $14 thousand and an income tax provision of $76 thousand for the three months ended June 30, 2006 and 2007, respectively. The income tax provision in 2007 represents the statutory requirements for state taxes. The income tax benefit of $14 thousand in 2006 was based upon the Company’s 2006 estimated effective annual tax rate of approximately (1)%. The difference between the federal statutory tax rate and the estimated effective tax rate in 2006 was primarily related to the expected utilization of certain of the Company’s net operating loss carryforwards and the impact of state taxes.

Discontinued operations

Management reevaluated the liability related to a discontinued operation from 1999 and determined that approximately $225 thousand was needed at June 30, 2006. Accordingly, $121 thousand, net of income tax of $4 thousand, was recognized as income from discontinued operations in the three months ended June 30, 2006.

Liquidity and Capital Resources

Since the Company’s incorporation in 1996, our primary source of liquidity had been cash received through the sale and issuance of equity and debt securities. We received equity investments between April 1999 and May 2003 in an aggregate amount of approximately $125.0 million. Our principal liquidity requirements have been for working capital, capital expenditures and general corporate purposes. On December 21, 2004, we completed our initial public offering and raised net proceeds of approximately $66.6 million.

17

During the six months ended June 30, 2007, we made approximately $3.5 million of capital expenditures related primarily to the purchase of computer equipment and telecommunications switching equipment and amounts paid for software development which was capitalized. At June 30, 2007 we had cash and cash equivalents of $24.6 million and marketable securities of $27.2 million. We also are party to a $25.0 million lending facility with Silicon Valley Bank, (“SVB”), under which we can borrow against our accounts receivable and general corporate assets. As of June 30, 2007, we had the full $25.0 million available to us, as no amounts were outstanding under this facility. Our current credit facility with SVB expires on November 30, 2007. We believe that our current cash balances and cash flows from operating activities, should be sufficient for us to fund our current operations for the foreseeable future. To the extent we require additional capital to fund our working capital or capital expenditures, we intend to seek additional financing in the credit or capital markets, although we may be unsuccessful in obtaining financing on acceptable terms, if at all.

The following table sets forth components of our cash flows for the following periods:

	Six Months Ended June 30,
	2006			2007
	($ in thousands)
Net cash provided by (used in) operating activities	$	3,971		$	(1,451	)
Net cash used in investing activities		(6,583	)		(628	)
Net cash provided by (used in) financing activities		1,478			(6,474	)

Cash provided by (used in) operating activities

Cash used in operations for the six months ended June 30, 2007 was primarily attributable to a net loss of $4.4 million and cash used by the change in operating net assets of $2.0 million, partially offset by non-cash expenses including depreciation and amortization of $4.2 million. Cash provided by operating activities for the six months ended June 30, 2006 was primarily attributable to net income of $0.6 million and depreciation and amortization of $3.5 million.

Cash used in investing activities

Total capital expenditures for the six months ended June 30, 2007 were $3.5 million related primarily to the purchase of computer equipment and telecommunications switching equipment and amounts paid to third parties for software development which were capitalized. Total purchases of marketable securities and total proceeds from sales and maturities of marketable securities for the six months ended June 30, 2007 were $25.4 million and $28.2 million, respectively. Total capital expenditures for the six months ended June 30, 2006 were $2.1 million related primarily to the purchase of telecommunications switching equipment and amounts paid to third parties for software development which were capitalized. Total purchases of marketable securities and total proceeds from sales and maturities of marketable securities for the six months ended June 30, 2006 were $27.2 million and $22.7 million, respectively.

Cash used in financing activities

Cash used in financing activities for the six months ended June 30, 2007 was primarily attributable to the repayment of $5.5 million in advances from SVB under the Non-Recourse Receivable Purchase Agreement, the purchase of $0.9 million of treasury stock under the previously mentioned stock purchase plan and the repayment of approximately $0.1 million in debt. Cash used in financing activities for the six months ended June 30, 2006 was primarily attributable to the borrowing of $1.8 million in advances from SVB under the Non-Recourse Receivable Purchase Agreement and the repayment of approximately $0.5 million in debt.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements or relationships with unconsolidated entities or financial partnerships, such as entities often referred to as special purpose entities, which are typically established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

18

Credit Risk Management

We manage the invoicing, credit risk and settlement of all traffic traded on our exchange. Since we are obligated to pay the seller regardless of whether we ultimately collect from the buyer, we assume the credit risk associated with all traffic traded on our exchange. As part of managing the credit risk associated with buyers on our exchange, we have an integrated credit risk management program under which the following arrangements assist in the mitigation of this credit risk:

• Netting. We net our members’ buying and selling activity. This enables us to extend credit to members up to the amount they have sold in a given period. The netting also reduces the working capital requirements for our members and for us. For the six months ended June 30, 2007, 30% of our trading revenues were offset by selling activity.

• Credit risk assessment and underwriting. GMAC Commercial Finance LLC (“GMAC”) and SVB each provide us with credit risk assessment and credit underwriting services. Under the terms of our agreements, GMAC and SVB assume the credit risk of selected members so that they may purchase voice calls or Internet capacity on our exchange.

• Self underwriting. Members can self-finance a credit line with us by prepaying, posting a cash deposit or letter of credit or by placing money in escrow.

• CreditWatch system. We enter a credit line for each member into our CreditWatch system, which is comprised of the sum of the GMAC credit line, SVB credit line, selling activity, other cash collateral and internal credit. The CreditWatch system regularly monitors a member’s net trading balance and sends email alerts to each member who surpasses 50%, 75% and 90% of its available credit limit and is able to automatically suspend a member’s ability to buy as its net balance reaches its total credit line.

• Frequent settlement. We have two trading periods per month. Payments from buyers are due fifteen days after the end of each trading period. This frequent settlement reduces the amount outstanding from our buyers. The frequent clearing of trading balances, together with the ability to net buy and sell transactions, allows our members to trade large dollar volumes while minimizing the outstanding balance that needs to be underwritten by additional sources of credit.

We occasionally issue internal credit lines to our members based on our review of a member’s financial statements and payment history with us. Typically, these internal credit lines are in addition to the credit lines issued by our third party underwriters. We evaluate the credit risk, on a case-by-case basis, of each member who is not covered by our third-party credit arrangements, our netting policy, prepayments or other cash collateral. For the six months ended June 30, 2007, approximately 90% of our trading revenues were covered by our third party underwriters, netting, prepayments or other cash collateral, of which 44% were covered by our third party underwriters. However, our credit evaluations cannot fully determine whether buyers can or will pay us for capacity they purchase through our exchange. In the future, we may elect to increase the amount of internal credit we extend to customers we deem creditworthy in order to reduce our credit underwriting costs. If buyers fail to pay us for any reason and we have not been able or have elected not to secure credit risk protection with respect to these buyers, our business could be adversely affected. In the event that the creditworthiness of our buyers deteriorates, our credit providers and we may elect not to extend credit and consequently we may forego potential revenues that could materially affect our results of operations.

We have certain minimum annual payments due pursuant to the terms of our agreements with each of GMAC and SVB. Pursuant to the terms of our agreement with GMAC and pursuant to the terms of our purchase agreement with SVB, which terminates on November 30, 2007, we are required to make aggregate minimum annual payments of $370,000. Under the terms of our agreement with GMAC, either party has the right to terminate the agreement upon one hundred twenty (120) days prior written notice.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Foreign currency exposure

The financial position and results of operations of our U.K. subsidiary are measured using the British pound as the functional currency. The foreign currency fluctuations have not had a material effect on our operating results or financial condition. Our exposure is mitigated, in part, by the fact that we incur certain operating costs in the same foreign currencies in which fee revenues are denominated. The percentage of fee revenues denominated in British pounds was approximately 12% for the year ended December 31, 2006 and 12% for the six months ended June 30, 2007.

Interest rate exposure

We are exposed to interest rate fluctuations. We invest our cash in short-term interest bearing securities. Although our investments are available for sale, we generally hold such investments to maturity. Our investments are stated at fair value, with net unrealized gains or losses on the securities recorded as accumulated other comprehensive income (loss) in shareholders’ equity. Net unrealized gains and losses were not material at December 31, 2006 or June 30, 2007. The fair market value of our marketable securities could be adversely impacted due to a rise in interest rates, but we do not believe such impact would be material. Securities with longer maturities are subject to a greater interest rate risk than those with shorter maturities and at June 30, 2007 our portfolio maturity was relatively short in duration. Assuming an average investment level in short-term interest bearing securities of $40.0 million, a one-percentage point decrease in the applicable interest rate would result in a $400,000 decrease in interest income.

Under the terms of our credit agreement with SVB, our borrowings bear interest at the prime rate. Therefore, a one-percentage point increase in the prime rate would result in additional annualized interest expense of $10,000 assuming $1.0 million of borrowings. At December 31, 2006 and June 30, 2007, we had no outstanding borrowings under this agreement.

Item 4. Controls and Procedures.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, (the “Exchange Act”)) as of June 30, 2007. In designing and evaluating our disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applied its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on this evaluation, our principal executive officer and principal financial officer concluded that, as of June 30, 2007, our disclosure controls and procedures were (1) designed to ensure that material information relating to us, including our consolidated subsidiaries, is made known to our principal executive officer and principal financial officer by others within those entities, particularly during the period in which this report was being prepared, and (2) effective, in that they provide that information required to be disclosed by us in our reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Security and Exchange Commission’s rules and forms.

No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended June 30, 2007 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART 2. OTHER INFORMATION

Item 1. Legal Proceedings.

The litigation process is inherently uncertain, and we cannot guarantee that the outcomes of the following proceedings and lawsuits will be favorable for us or that they will not be material to our business, results of operations or financial position. However, the Company does not currently believe that these matters will have a material adverse effect on our business, results of operations or financial position.

World Access Proceeding

On March 18, 2003, World Access, Inc. f/k/a WAXS, Inc., WA Telcom Products Co., Inc., WorldxChange Communications, Inc., Facilicom International LLC and World Access Telecommunications Group, Inc. f/k/a Cherry Communications Incorporated d/b/a Resurgens Communications Group (collectively “the Debtors”), filed a lawsuit against us in the United States Bankruptcy Court for the Northern District of Illinois, Eastern Division. The Debtors had previously filed for bankruptcy under Chapter 11 of the United States Bankruptcy Code. The Debtors seek recovery of certain payments they made to us as a buyer on our exchange, which total approximately $855,000. The Debtors claim that such payments were preferential transfers under the Bankruptcy Code. The Debtors also seek costs and expenses, including attorneys’ fees and interest. We filed an answer to the complaint on April 18, 2003, denying the Debtors’ claims for relief and asserting several affirmative defenses. On August 12, 2003, we served discovery on the attorneys for World Access and its related entities. Shortly after we served our discovery, the bankruptcy judge entered an order stating that the cases of World Access and its related entities, which had been jointly administered, could not be substantively consolidated. Since then the majority of Debtors’ preference complaints in the case have been continued. In September 2004, the Debtors confirmed a Plan of Liquidation that created a trust to proceed with liquidating avoidance actions. The Trustee has been substituted as the Plaintiff in all avoidance actions. At a scheduling conference held on October 12, 2005, the Court set discovery cut-off dates that have been continued for cases where the Trustee seeks to recover in excess of $100,000, at the request of the Trustee. Plaintiff’s responses to certain discovery requests were due in November. The current discovery schedule designates August 13, 2007 as the deadline for all discovery. Based on the revised discovery plan and a statement from the Court at the scheduling conference, it does not appear that the Court will be ready to try any of the adversary proceedings before the fourth quarter of 2007.

Octane Proceeding

On May 27, 2003, we received a demand letter from counsel for Octane Capital Management and its affiliate, Octane Capital Fund I, L.P. (collectively “Octane”), demanding the right to purchase up to $2.8 million of our shares of Series E preferred stock on the same terms as originally set forth in a Securities Purchase Agreement dated as of July 3, 2001. Additionally, the letter demanded the right to convert Octane’s investment in shares of our Series D preferred stock into shares of Series D-1 preferred stock pursuant to the terms of such purchase agreement.

The Octane demand letter also alleged violations of Octane’s rights under a Second Amended and Restated Investors’ Rights Agreement dated as of March 7, 2000 (the “Investors’ Rights Agreement”), including, among other allegations, the allegation that Octane did not receive proper advance notice of the complete terms of our Series E preferred stock offering. Arbinet denies all of the allegations. On May 28, 2003, we sent notice to all stockholders, including Octane, indicating our plan to defend against these claims.

On September 1, 2004, after no contact with us for over a year, Octane contacted our representatives to renew its demand against us. We responded to Octane’s demand, denying all allegations of wrongdoing.

On December 10, 2004, we received a complaint filed that day by Octane and Amerindo Technology Growth Fund II Inc. (“ATGF”), another investor of the Company, in the United States District Court for the Southern District of New York, entitled Octane Capital Fund, L.L.P. et al. v. Arbinet-thexchange, Inc., Civil Action No. 04-CV-9759 (KMW). Octane and ATGF filed an amended complaint with the court on December 13, 2004, amending and replacing the December 10, 2004 complaint. The amended complaint alleged, among other things, that we breached terms of the Investors’ Rights Agreement by failing to give Octane and ATGF proper advance notice of the complete terms of our Series E preferred stock offering. The amended complaint sought money damages for both Octane and ATGF for the alleged breach of contract. On February 11, 2005, we filed our answer to the amended complaint, denying all liability, and filed counterclaims against Octane and ATGF for, among other claims, breach of the Investors’ Rights Agreement in connection with their conduct seeking additional shares of stock and other relief.

21

On May 9, 2005, the plaintiffs filed an unopposed motion to dismiss this case in federal court without prejudice for lack of subject matter jurisdiction. The court granted the plaintiffs’ motion on the same day. On November 4, 2005, Octane renewed the lawsuit by filing a substantially similar complaint in the Superior Court of New Jersey, Middlesex County, in an action entitled Octane Capital Fund I, L.P. v. Arbinet-thexchange, Inc., Docket No. MID-L-7990-05. Octane is the only plaintiff in the case. On October 3, 2006, we filed an answer denying all liability and asserting counterclaims against Octane for, among other reasons, breach of the Investors’ Rights Agreement in connection with Octane’s conduct seeking additional shares of stock and other relief. Octane filed its answer on October 27, 2006, denying all liability on our counterclaims.

On July 12, 2007, the parties entered into a Settlement Agreement and Release the impact of which has been recorded in the “Provision for Litigation” as of June 30, 2007. A voluntarily dismissal with prejudice was entered on July 24, 2007.

Mashinsky Series E Proceeding

On May 13, 2005, we received a letter from counsel representing Alex Mashinsky, our founder, former officer and a current director, together with a draft complaint and a draft press release, threatening to commence litigation in the Southern District of New York against us, as well as against Communications Ventures III, L.P., one of our stockholders, former director Anthony L. Craig, former director Roland A. Van der Meer, and our former President, Chief Executive Officer and director, J. Curt Hockemeier, if we do not agree to an “amicable settlement” with him. Mr. Mashinsky alleges breach of fiduciary duty, self-dealing, fraud, and breach of contract in connection with our Series E preferred stock offering consummated in 2001, asserting over $90 million in damages. According to his correspondence he “is prepared to discuss settlement of this matter at an amount representing a significant discount.” By letter dated May 31, 2005, the Company and other potential defendants responded to Mr. Mashinsky’s letter, denying any liability and describing potential counterclaims that would be asserted against Mr. Mashinsky should he pursue his claims.

On July 13, 2007, the Company entered into an agreement with Mr. Mashinsky in which he agreed, among other things, to release the Company from any claims relating to the Series E preferred stock offering, including, but not limited to, the allegations outlined in the May 13, 2005 letter. The impact of this agreement has been recorded in the “Provision for Litigation” as of June 30, 2007.

World-Link Proceeding

On December 15, 2005, Arbinet filed a patent infringement lawsuit against World-Link Telecom, Inc. in the U. S. District Court in the Eastern District of New York. Arbinet asserts that World-Link has infringed three of its U.S. patents relating to the trading of telecommunications capacity, namely, U.S. Patent Nos. 6,226,365; 6,442,258; and 6,542,588. By its Complaint, Arbinet seeks damages and injunctive relief.

World-Link filed its Answer and Counterclaims to the Complaint on January 23, 2006. By its Answer, World-Link denied Arbinet’s infringement allegations and asserted that the claims of the patents in suit are invalid. World-Link also asserted a counterclaim for declaratory judgment that it did not infringe the patents in suit and that the patents in suit were invalid, and counterclaims for tortuous interference with contractual relations and monopolization or attempted monopolization under Section 2 of the Sherman Act.

On February 8, 2006, the parties attended an initial conference with the Magistrate Judge assigned to the case for the purposes of setting a schedule for the case. No case schedule has been issued yet. Discovery has begun in the case. The parties negotiated and the court entered a Protective Order to govern the treatment of the confidential and proprietary information of the parties during the case. On March 30, 2006, we served a set of discovery requests on counsel for World-Link. Shortly thereafter, World-Link served discovery requests on our counsel. World-Link responded to our discovery requests and produced documents to us on June 1, 2006. We responded to World-Link’s discovery requests on June 8, 2006 and produced documents to World-Link subsequently. On September 22, 2006, the Court issued an order referring the case to mediation. The parties exchanged settlement proposals during mediation and the mediation ended without an agreement. The parties exchanged proposed construction of patent claim terms on March 8, 2007, and were scheduled to serve opening briefs on claim construction on March 29, 2007. However, prior to the March 29 deadline, World-Link filed a motion for a proposed consent judgment, which proposal does not require an admission of infringement. Since such consent judgment would be meaningless, as it will allow World-Link to continue its infringing acts, Arbinet filed an opposition to this motion.

22

On March 15, 2007, World-Link’s lead counsel filed a motion to withdraw as counsel citing Arbinet’s allegation of willful infringement, despite Arbinet’s offer to accommodate (and even though Arbinet’s original filed complaint alleges willful infringement). On March 21, 2007, World-Link filed a motion to stay discovery on the ground that the proposed consent judgment rendered further discovery unnecessary. Arbinet opposed the motion to stay discovery, as it needs to uncover certain facts surrounding World-Link’s infringement and the willfulness of such tortuous act. On April 3, 2007, Arbinet filed a motion to add other World-Link affiliates as defendants in this action. On the morning of April 5, 2007, the day of the scheduled status conference, World-Link submitted a letter stating that it has filed a voluntary petition under Chapter 11 of the Bankruptcy Code. At the April 5 status conference, World-Link’s bankruptcy counsel represented that the action is automatically stayed. Arbinet promptly served a new complaint on the World-Link affiliates later that day. On April 13, 2007, Arbinet submitted a letter to the Court contending that the bankruptcy proceeding initiated by World-Link does not automatically stay, among other things, Arbinet’s motion to add non-bankrupt World-Link affiliates in the pending World-Link action. On April 27, 2007, Arbinet filed, in the US Bankruptcy Court, District of New Jersey, where World-Link Telecom’s bankruptcy petition is pending, (i) a motion for an order determining that Section 362(a) of the Bankruptcy Code does not preclude the continued prosecution of an action for injunctive relief against post-petition patent infringement, and (ii) a motion for relief from stay, to the extent necessary, to allow the remainder of the action to proceed. On April 30, 2007, World-Link Telecom filed in the bankruptcy court a motion for an entry of an order authorizing World-Link Telecom to enter into a common interest agreement with its affiliated entities in defense of Arbinet’s patent infringement claims.

The parties have recently engaged in discussions to resolve this matter and have agreed to submit this matter to mediation if such discussions are unsuccessful.

CHVP Proceeding

On April 6, 2006, CHVP Founders Fund I, L.P. (“CHVP”) filed a lawsuit against us in the Supreme Court of the State of New York, County of New York. CHVP seeks damages of over $1.87 million related to the transfer, by our founder and current director, Alex Mashinsky, of three million shares of our common stock to CHVP. CHVP had previously been sued by Mr. Mashinsky regarding the same transfer of shares. CHVP claims that we interfered with its ability to sell the shares during a 90-day period from December 2004 to March 2005, and alleges claims for violation of the Uniform Commercial Code, conversion, and breach of contract. On May 22, 2006, we filed our Answer and Counterclaim denying liability, and asserting counterclaims against CHVP for a declaratory judgment that the transfer of Mr. Mashinsky’s shares to CHVP is void or voidable, that Arbinet did not improperly interfere with CHVP’s sale of Arbinet stock during the lock up period, and that Mr. Mashinsky’s shares were subject to a particular market stand-off restriction pursuant to operative agreements. In addition, we filed a Third Party Complaint against Mr. Mashinsky requesting the same declaratory judgment described above, and asserted claims for breach of contract, breach of implied covenant of good faith and fair dealing, negligence, indemnification, and common law contribution in connection with Mr. Mashinsky’s transfer of Arbinet shares to CHVP. As of May 11, 2007, the matter was settled between the parties the impact of which has been recorded in the “Provision for Litigation” as of June 30, 2007.

The action was dismissed with prejudice on May 29, 2007.

Item 1A Risk Factors

Recent changes in our senior management may be disruptive to our business.

On June 11, 2007, J. Curt Hockemeier, our former Chief Executive Officer and President, resigned. Roger H. Moore, one of our Directors, is serving as Interim Chief Executive Officer and President while the Board conducts a search for a permanent Chief Executive Officer. This change in our senior management may prove disruptive to our business and there may be uncertainty among our investors, members, employees, and others concerning our future direction and performance. Further, once we do obtain a permanent Chief Executive Officer, we cannot be certain how much time will be required to make the transition to new management, which may adversely affect our financial condition or disrupt our business. If we are unable to identify and retain an effective permanent Chief Executive Officer in a timely manner, or at all, our financial condition may be adversely affected.

Other than the changes stated above, there have been no material changes in the risk factors described in Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2006.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

(b) Use of Proceeds from Registered Securities

On December 21, 2004, we sold 4,233,849 shares of our common stock in connection with the closing of our initial public offering. The Registration Statement on Form S-1 (Reg. No. 333-117278) we filed to register our common stock in the offering was declared effective by the Securities and Exchange Commission on December 16, 2004.

After deducting expenses of the offering, we received net offering proceeds of approximately $66.6 million. We used approximately $15.2 million of our net proceeds to redeem the outstanding shares of our Series B and Series B-1 preferred stock and approximately $10.0 million to repay principal and interest outstanding under our credit facility with SVB. Approximately $40.0 million of the net proceeds of the offering have been invested in investment-grade marketable securities within the guidelines defined in our investment policy. Such funds remain invested in such securities as of June 30, 2007. The remaining proceeds have been used for working capital purposes. We regularly assess the specific uses and allocations for the remaining funds.

(c) The following table provides information as of and for the quarter ended June 30, 2007 regarding shares of the Company’s common stock that were repurchased under the Company’s stock repurchase program (the “Repurchase Plan”).
