PART I



|ITEM 1. | DESCRIPTION OF BUSINESS
|------- | -----------------------

LIQUIDATION, WINDING UP AND DISSOLUTION

On August 6, 2003, our board of directors approved, subject to stockholder approval at our 2003 Annual Meeting of Stockholders, the liquidation and
dissolution of Turnstone Systems, Inc. pursuant to a plan of complete liquidation and dissolution. The holders of a majority of our outstanding shares approved the plan of complete liquidation and dissolution on November 11, 2003. The key
features of the plan are (1) file a certificate of dissolution with the Secretary of State of the State of Delaware; (2) cease conducting normal business operations, except as may be required to wind up our business affairs;
(3) attempt to convert all of our remaining assets into cash or cash equivalents in an orderly fashion; (4) pay or attempt to adequately provide for the payment of all of our known obligations and liabilities; and (5) distribute pro
rata in one or more liquidating distributions all of our remaining assets to our stockholders as of the applicable record date.

In connection with the
adoption of the plan and the anticipated liquidation, we adopted the liquidation basis of accounting effective November 11, 2003, whereby assets are valued at their estimated net realizable cash values and liabilities are stated at their
estimated settlement amounts. Uncertainties as to the precise net value of our non-cash assets, and the ultimate amount of our liabilities make it impracticable to predict the aggregate net value that may ultimately be distributable to stockholders.
Claims, liabilities and future expenses for operations will continue to be incurred with execution of the plan. These costs will reduce the amount of net assets available for ultimate distribution to stockholders. Although we do not believe that a
precise estimate of those expenses can currently be made, we believe that available cash will be adequate to provide for our obligations, liabilities, operating costs and claims, and to make cash distributions to stockholders. If available cash is
not adequate to provide for our obligations, liabilities, operating costs and claims, estimated future distributions of cash to our stockholders will be reduced.

We filed our certificate of dissolution with the Secretary of State of the State of Delaware effective December 4, 2003. Pursuant to Delaware law, Turnstone Systems, Inc. will continue in existence until at least December 4, 2006.
During this period, we are not permitted to continue our business as a going concern.

At the close of business on December 4, 2003, we closed our
stock transfer books, discontinued recording transfers of our common stock, and our common stock was de-listed from the Nasdaq National Market. Any future distributions we make will be made solely to the stockholders of record as of the close of
business on December 4, 2003. We have sought and will continue to attempt to seek relief from the Securities and Exchange Commission from the reporting requirements under the Exchange Act, but to date we have not been successful in obtaining
relief.

Since we were de-listed from the Nasdaq National Market and closed our stock records on December 4, 2003, our shares have continued to trade
in the Over the Counter Markets pink sheets. From time to time, trading volume in our shares has been relatively high, and our shares have traded at prices in excess of the highest price we have estimated for potential liquidation
distributions. Traders in our shares are cautioned that our shares are highly speculative, and we cannot predict with any accuracy when, or if, additional liquidation distributions will be made.

In June 2004, our board of directors approved a partial liquidating cash distribution of approximately $10.8 million, or $0.17 per common share, to our stockholders of
record as of December 4, 2003. The distribution was completed on July 8, 2004. At the end of June 2004, we also terminated the employment of Albert Y. Liu, General Counsel & Director of Human Resources, and Eric S. Yeaman, Chief
Executive Officer and Chief Financial Officer, our two remaining employees, and concurrently entered into consulting agreements with each of them to continue ongoing management of our liquidation. Compensation under these consulting agreements is
based on actual hours of service at a fixed hourly rate of $125. The agreements do not provide for minimum retainer payments or termination fees.

As of
December 31, 2006, we had one outstanding litigation matter remaining related to our initial public offering of common stock in 2000. In 2005 the district court had preliminarily approved a proposed settlement of the matter that we believe
would not have

required any cash contribution from us, and therefore would have allowed us to make a final liquidating distribution at the end of 2006. However, in December
2006 and prior to the proposed settlement being finalized, a federal appeals court decertified the IPO class action at the request of the defendant underwriters, which resulted in the proposed settlement being stayed until the plaintiffs
appeal of such decision is completed. We are uncertain as to the timing of the appeal process and whether the proposed settlement would remain available if the appeal is denied and the class action remains decertified. We are currently evaluating
whether it is in the best interest of stockholders for us to make a final distribution prior to the resolution of the IPO litigation matter, or whether it is best to wait until the matter is resolved with finality before making our final
distribution. For a more detailed discussion of this litigation matter, please see the section entitled IPO Litigation under Item 3  Legal Proceedings.

Based on our projections of operating expenses and liquidation costs as of December 31, 2006, we estimate that the amount of future liquidating distributions will be approximately $0.016 per common share. The
actual amount available for distribution, if any, could be substantially less if we incur unexpected or greater than expected expenses related to the IPO litigation matter or if we discover additional liabilities or claims or incur other unexpected
or greater than expected expenses.

We may at some point determine that the continued liquidation of Turnstone may be more efficiently handled by retaining
a third party liquidator to manage the liquidation process.

COMPANY INFORMATION

We were formerly a provider of hardware and software products that enabled local exchange carriers to deploy and maintain copper local loop services. Our products included copper loop management and testing systems,
signal splitters and remote line switching and service verification platforms.

We were incorporated in Delaware in January 1998. Our principal executive
offices are located at 7650 Marathon Drive, Suite A, Livermore, California 94550, and our telephone number is (408) 907-1400.

EMPLOYEES

As of February 1, 2007, we had no full-time employees.

RISK FACTORS

In addition to other information in this Form 10-KSB, the following risk factors should be carefully considered in evaluating us and our liquidation and
dissolution because such factors may have a significant impact on the execution of our plan of dissolution and the timing and amount of liquidating distributions, if any, to our stockholders. As a result of the risk factors set forth below and
elsewhere in this Form 10-KSB, and the risks discussed in our other Securities and Exchange Commission filings, actual results could differ materially from those projected in any forward-looking statements.

We cannot assure you of the exact amount or timing of any future distribution to our stockholders under the plan of dissolution.

The liquidation and dissolution process is subject to numerous uncertainties and may not result in any remaining capital for future distribution to our
stockholders. The precise nature, amount and timing of any future distribution to our stockholders will depend on and could be delayed by, among other things, the resolution of the outstanding IPO litigation matter, sales of our non-cash assets,
claim settlements with creditors, resolution of outstanding litigation matters, and unexpected or greater than expected expenses. Furthermore, we cannot provide any assurances that we will actually make additional distributions. The estimates we
have provided are based on currently available information, and actual payments, if any, could be substantially less than the amount we have estimated. Any amounts to be distributed to our stockholders may be less than the price or prices at which
our common stock has recently traded or may trade in the future.

Our common stock is continuing to trade even though we are in the process of liquidation and liquidating
distributions, if any, may be below any trading price.

Until December 4, 2003, when our certificate of dissolution became
effective and we voluntarily de-listed our common stock and closed our transfer books, our common stock was traded on the Nasdaq National Market under the symbol "TSTN." Since the de-listing, our common stock has been trading in the Over the Counter
Market's "pink sheets" under the symbol "TSTN.PK." It has been trading under "due-bill" contractual obligations between the seller and purchaser of the stock, who negotiate and rely on themselves with respect to the allocation of stockholder
proceeds arising from ownership of the shares. No assignments or transfers of our common stock were recorded or will be recorded after December 4, 2003. Trading in our stock is highly speculative and the market for our stock is highly illiquid.
The only value associated with our shares is the right to receive further distributions as part of the liquidation process. Because of the difficulty in estimating the amount and timing of the liquidating distributions, and due to the other risk
factors discussed herein, our common stock may be subject to significant volatility and may trade above the amount of any liquidating distribution that is made.

We may not be able to settle all of our obligations to creditors and resolve all of our outstanding litigation.

If we do not settle all of
our obligations to creditors and resolve all of our outstanding litigation, we may be prevented from completing our plan of dissolution. Our obligations to creditors may include, among other things, long-term contractual obligations to certain
customers, including certain product warranties, and contractual obligations to certain of our vendors. Our outstanding litigation includes federal securities class action litigation and litigation arising out of our ordinary course of business. As
part of the wind down process, we will attempt to settle our obligations with our creditors and resolve all of the outstanding litigation. In particular, we had reached a tentative settlement of the federal securities class action lawsuit related to
our initial public offering that we believe would have required no cash contribution from us. The proposed settlement was stayed in December 2006 as a result of the decertification of the class action lawsuit by a federal appeals court, which is
being appealed. We are uncertain about the timing of the appeal process and whether the proposed settlement would remain available if the class action remains decertified after appeal. Plaintiffs in the class action lawsuit have claimed damages in
the hundreds of millions of dollars. Our inability to reach settlement with our creditors and resolve outstanding litigation could delay or even prevent us from completing the plan of dissolution. Moreover, amounts required to settle our obligations
to creditors and resolve any outstanding litigation will reduce the amount of remaining capital available for future distribution to stockholders.

We
will continue to incur claims, liabilities and expenses that will reduce the amount available for distribution out of the liquidation to stockholders.

Claims, liabilities and expenses incurred during the wind down process, such as legal, accounting and consulting fees and miscellaneous office expenses, will reduce the amount of assets available for future
distribution out of the liquidation to stockholders. If available cash and amounts received on the sale of non-cash assets are not adequate to provide for our obligations, liabilities, expenses and claims, we may not be able to distribute out of the
liquidation meaningful cash, or any cash at all, to our stockholders.

Distribution of assets out of the liquidation, if any, to our stockholders could
be delayed.

We are currently unable to predict the precise timing of any liquidating distributions. The timing of such distributions
will depend on and could be delayed by, among other things, the resolution of the outstanding IPO litigation matter, the timing of sales of our non-cash assets, claim settlements with creditors and the settlement of any other outstanding litigation
matters. Additionally, a creditor could seek an injunction against the making of such distributions to our stockholders on the ground that the amounts to be distributed were needed to provide for the payment of our liabilities and expenses. Any
action of this type could delay or substantially diminish the amount available for such distribution to our stockholders.

##### Table of Contents

If we fail to create an adequate contingency reserve for payment of our expenses and liabilities, each stockholder
could be held liable for payment to our creditors of his or her pro rata share of amounts owed to creditors in excess of the contingency reserve, up to the amount actually distributed to such stockholder.

We filed our certificate of dissolution with the Secretary of State of the State of Delaware effective December 4, 2003. Pursuant to the Delaware
General Corporation Law, we will continue to exist for three years after the certificate of dissolution is filed or for such longer period as the Delaware Court of Chancery shall direct, for the purpose of prosecuting and defending suits against us
and enabling us gradually to close our business, to dispose of our property, to discharge our liabilities and to distribute to our stockholders any remaining assets. Under the Delaware General Corporation Law, in the event we fail to create during
this three-year period an adequate contingency reserve for payment of our expenses and liabilities, each stockholder could be held liable for payment to our creditors of such stockholders pro rata share of amounts owed to creditors in excess
of the contingency reserve, up to the amount actually distributed to such stockholder.

Although the liability of any stockholder is
limited to the amounts previously received by such stockholder from us (and from any liquidating trust or trusts) in the dissolution, this means that a stockholder could be required to return all distributions previously made to such stockholder and
receive nothing from us under the plan of dissolution. Moreover, in the event a stockholder has paid taxes on amounts previously received, a repayment of all or a portion of such amount could result in a stockholder incurring a net tax cost if the
stockholders repayment of an amount previously distributed does not cause a commensurate reduction in taxes payable. While we will endeavor to make adequate reserves for all known, contingent, and unknown liabilities, there is no guarantee
that the reserves established by us will be adequate to cover all such expenses and liabilities.

We will continue to incur the expenses of complying
with public company reporting requirements.

We have an obligation to continue to comply with the applicable reporting requirements of
the Securities Exchange Act of 1934, as amended, referred to as the Exchange Act, even though compliance with such reporting requirements is economically burdensome. We have sought and will continue to attempt to seek relief from the
Securities and Exchange Commission from the reporting requirements under the Exchange Act, but to date we have not been successful in obtaining relief. We anticipate that, if such relief were granted, we would continue to file current reports on
Form 8-K to disclose material events relating to our liquidation and dissolution along with any other reports that the Securities and Exchange Commission might require. However, the Securities and Exchange Commission may not grant any such relief,
and we do not anticipate we will be successful in obtaining relief while active trading of our shares is continuing.

Our board of directors may at any
time turn management of the liquidation of Turnstone Systems over to a third party, and some or all of our directors may resign from our board at that time.

Our board of directors may at any time turn our management over to a third party to complete the liquidation of our remaining assets and distribute the available proceeds to our stockholders, and some or all of our
directors may resign from our board at that time. Our board of directors currently consists of Eric S. Yeaman, our Chief Executive Officer and Chief Financial Officer, and Albert Y. Liu, our General Counsel and Director of Human Resources, who are
overseeing our liquidation on a consulting basis. If management is turned over to a third party and all of our directors resign from our board, the third party would have sole control over the liquidation process, including the sale or distribution
of any remaining assets.

If we are deemed to be an investment company, we may be subject to substantial regulation that would cause us to incur
additional expenses and reduce the amount of assets available for distribution.

If we invest our cash and/or cash equivalents in
investment securities, we may be subject to regulation under the Investment Company Act of 1940. If we are deemed to be an investment company under the Investment Company Act because of our investment securities holdings, we must register as an
investment company under the Investment Company Act. As a registered investment company, we would be subject to the further regulatory oversight of the Division of Investment Management of the Securities and Exchange Commission, and our activities
would be subject to substantial regulation under the Investment Company Act. Compliance with these regulations would cause us to incur additional expenses, which would reduce the amount of assets available for distribution to our stockholders. To
avoid these compliance costs, we intend to invest our cash proceeds in money market funds and government securities, which are exempt from the Investment Company Act but which currently provide a very modest return.

Because our products have been deployed in complex environments, they may have errors or defects that are found only
after they have been fully deployed, which could result in liability claims against us.

Because our products are designed to provide
critical services in large and complex networks, if errors, defects or failures are discovered in our products, we may be exposed to significant legal claims. Any claims, with or without merit, could increase our expenses and reduce assets available
for distribution in liquidation. Although we maintain product liability insurance covering some damages arising from implementation and use of our products, our insurance may not fully cover claims brought against us. Liability claims could require
us to spend significant time and money in litigation or to pay significant damages.

Our products incorporate numerous component parts
designed and manufactured by third parties. We cannot assure you that these third-party parts are free of defects or errors. Given the complex nature of our products and our dependence on a large number of highly intricate third-party component
parts, our products may contain defects or errors not detectable during our quality assurance and testing procedures. Any such defects or errors could result in legal claims against us.

|ITEM 3. | LEGAL PROCEEDINGS
|------- | -----------------

We dispute, but cannot assure you that we will be
successful in our defense of, the outstanding lawsuit against us described below. If we are unsuccessful, the lawsuit could have a material adverse effect on our financial condition and on the amount of assets available for distribution to
stockholders. Even if we are successful in defending against these claims, the litigation could result in substantial costs.

IPO
Litigation

On November 9, 2001, Arthur Mendoza filed a securities class action lawsuit in the United States District Court for the Southern
District of New York alleging claims against us, certain of our current and former officers and directors, and the underwriters of our initial public offering of stock as well as our secondary offering of stock. The complaint is purportedly brought
on behalf of a class of individuals who purchased common stock in our initial public offering and our secondary stock offering between January 31 and December 6, 2000. The complaint alleges generally that the prospectuses under which such
securities were sold contained false and misleading statements with respect to discounts and commissions received by the underwriters. The case has been coordinated for pre-trial purposes with over 300 cases raising the same or similar issues
and also currently pending in the Southern District of New York. On April 18, 2002, Michael Szymanowski was appointed lead plaintiff in the action. On April 22, 2002, an amended complaint was filed. On July 1, 2002, the underwriter
defendants filed an omnibus motion to dismiss. On July 15, 2002, we, collectively with the other issuer defendants, also filed an omnibus motion to dismiss. The lead plaintiff filed an opposition to the underwriters motion to dismiss on
August 15, 2002 and to the issuers motion to dismiss on August 27, 2002. The underwriters reply to the opposition was filed on September 13, 2002, and our reply to the opposition was filed on September 27, 2002. On
February 19, 2003, the district court issued an order denying the motions to dismiss with respect to substantially all of the plaintiffs claims, including those against us. In February 2005, the district court granted preliminary approval
for a proposed settlement and release of claims against the issuer defendants, including Turnstone. In April, June and October 2006, the district court judge met with the issuer defendants and their insurance companies to review the fairness of the
proposed settlement. In December 2006, as a result of an appeal by the underwriter defendants, the second circuit court of appeals issued a decision to decertify the class action. As a result, the district court has stayed the proposed settlement
pending plaintiffs appeal of the decertification decision. Plaintiffs in this class action lawsuit have claimed damages in the hundreds of millions of dollars. If the settlement does not occur, and litigation against us continues, we believe
we have meritorious defenses and intend to defend the case vigorously.

In June 2004, our board of directors approved a liquidating cash distribution of approximately
$10.8 million, or $0.17 per common share, to our stockholders of record as of December 4, 2003. The distribution was completed on July 8, 2004. All future distributions will be liquidating distributions. The actual amount and timing of
future liquidating distributions, if any, cannot be predicted at this time. At present, we estimate that total future liquidating distributions will be approximately $0.016 per share.

EQUITY COMPENSATION PLANS

The information required by this Item regarding securities reserved for issuance
under equity compensation plans is incorporated by reference to the information set forth in Item 11 of this Annual Report on Form 10-KSB.



|ITEM 6. | MANAGEMENTS DISCUSSION AND ANALYSIS OR PLAN OF OPERATION
|------- | ---------------------------------------------------------

OVERVIEW

On August 6, 2003, our board of directors approved, subject to stockholder ratification at our 2003 Annual Meeting of Stockholders, a special cash
distribution to stockholders of $2.77 per common share or such lesser amount as the board of directors might later determine to be appropriate. The board of directors also approved, subject to stockholder approval at our 2003 Annual Meeting of
Stockholders, the liquidation and dissolution of Turnstone Systems, Inc. pursuant to a plan of complete liquidation and dissolution.

The special cash
distribution was ratified by a majority of the shares present at the Annual Meeting on November 11, 2003. Following the Annual Meeting, our board of directors approved a special distribution of $2.77 per common share payable on
November 28, 2003 to our stockholders of record as of November 21, 2003. The special cash distribution to stockholders, totaling $175.7 million, was paid on November 28, 2003.

On November 11, 2003, the holders of a majority of our outstanding shares approved the plan of dissolution. The key features of the plan are (1) file a
certificate of dissolution with the Secretary of State of the State of Delaware; (2) cease conducting normal business operations, except as may be required to wind up our business affairs; (3) attempt to convert all of our remaining assets
into cash or cash equivalents in an orderly fashion; (4) pay or attempt to adequately provide for the payment of all of our known obligations and liabilities; and (5) distribute pro rata in one or more liquidating distributions all of our
remaining assets to our stockholders as of the applicable record date.

##### Table of Contents

We filed our certificate of dissolution with the Secretary of State of the State of Delaware effective December 4,
2003. Pursuant to Delaware law, Turnstone Systems, Inc. will continue in existence until at least December 4, 2006. During this period, we will continue to convert our estimated net assets to cash for future distribution to our stockholders. We
are not permitted to continue our business as a going concern.

At the close of business on December 4, 2003, we closed our stock transfer books,
discontinued recording transfers of our common stock, and our common stock was de-listed from the Nasdaq National Market. Any future distributions we make will be made solely to our stockholders of record as of the close of business on
December 4, 2003.

In June 2004, our board of directors approved a liquidating cash distribution of approximately $10.8 million, or $0.17 per common
share, to our stockholders of record as of December 4, 2003. The distribution was completed on July 8, 2004. At the end of June 2004, we also terminated the employment of Albert Y. Liu, General Counsel & Director of Human
Resources, and Eric S. Yeaman, Chief Executive Officer and Chief Financial Officer, our two remaining employees, and concurrently entered into consulting agreements with each of them to continue ongoing management of our liquidation. Compensation
under these consulting agreements is based on actual hours of service at a fixed hourly rate of $125. The agreements do not provide for minimum retainer payments or termination fees.

As of December 31, 2006, we had one outstanding litigation matter remaining related to our initial public offering of common stock in 2000. In 2005 the district court had approved a preliminary settlement of the
matter that we believe would not have required any cash contribution from us, and therefore would have allowed us to make a final liquidating distribution at the end of 2006. However, in December 2006 and prior to the proposed settlement being
finalized, a federal appeals court decertified the IPO class action at the request of the defendant underwriters, which resulted in the proposed settlement being stayed until the plaintiffs appeal of such decision is completed. We are
uncertain as to the timing of the appeal process and whether the proposed settlement will remain available if the appeal is denied and the class action remains decertified. We are currently evaluating whether it is in the best interest of
stockholders for us to make a final distribution prior to the resolution of the IPO litigation matter, or whether it is best to wait until the matter is resolved with finality before making our final distribution. For a more detailed discussion of
this litigation matter, please see the section entitled IPO Litigation under Item 3  Legal Proceedings.

Based on our
projections of operating expenses and liquidation costs as of December 31, 2006, we estimate that the amount of future liquidating distributions will be approximately $0.016 per common share. The actual amount available for distribution, if
any, could be substantially less if we incur unexpected or greater than expected expenses related to the IPO litigation matter or if we discover additional liabilities or claims or incur unexpected or greater than expected expenses.

Prior to the decision to dissolve Turnstone Systems, Inc., we were a provider of hardware and software products that enabled local exchange carriers to deploy and
maintain copper local loop services. Our products included copper loop management and testing systems, signal splitters and remote line switching and service verification platforms.

CRITICAL ACCOUNTING ESTIMATES

In connection with the adoption of the plan of dissolution and the anticipated liquidation,
we adopted the liquidation basis of accounting effective November 11, 2003, whereby assets are valued at their estimated net realizable cash values and liabilities are stated at their estimated settlement amounts. The preparation of
consolidated financial statements using the liquidation basis of accounting requires us to make assumptions, judgments and estimates that can have a significant impact on our reported net assets in liquidation. We base our assumptions, judgments and
estimates on the most recent information available and various other factors that we believe to be reasonable under the circumstances. Actual results could differ materially from these estimates under different assumptions or conditions. On a
regular basis we evaluate our assumptions, judgments and estimates and make changes accordingly. We believe that the assumptions, judgments and estimates involved in accounting for estimated costs to be incurred during liquidation have the greatest
potential impact on our consolidated financial statements.

##### Table of Contents

Estimated Costs to be Incurred During Liquidation

Under the liquidation basis of accounting, we accrue for the remaining costs to be incurred during liquidation, including consulting fees for Eric S. Yeaman and Albert Y. Liu, fees of professional service providers
and miscellaneous other costs, partially offset by estimated future interest earnings. Such remaining costs were estimated at $85,000 at December 31, 2006. Our estimates are based on assumptions regarding our ability to settle outstanding
obligations to creditors, resolve outstanding litigation, successfully petition the Securities and Exchange Commission for relief from public company reporting requirements, and the timing of distributions to stockholders. If there are delays, or we
are not successful, in achieving these objectives, actual costs incurred during liquidation may increase, reducing net assets available in liquidation.

##### Table of Contents

LIQUIDITY AND CAPITAL RESOURCES

As of December 31, 2006, net assets in liquidation totaled $1,053,000, consisting of $1,138,000 in cash and cash equivalents partially offset by $85,000 of estimated costs to be incurred during liquidation. We expect to use our capital
resources to execute our complete plan of liquidation and dissolution, settle existing claims against the company, including existing litigation and other current liabilities and accrued expenses, and to make liquidating distributions to
stockholders. Capital resources available for liquidating distributions to stockholders may vary if we incur greater than estimated operating expenses associated with executing the plan of complete liquidation and dissolution, actual settlement
costs for existing claims against the company vary from estimates, or if there are existing, but unknown claims made against us in the future. At December 31, 2006, our cash and cash equivalents were held primarily in money market funds. We
expect to continue to hold our cash and cash equivalents primarily in money market funds while we execute the plan of dissolution.

We do not have any
long-term debt, lease or purchase obligations at December 31, 2006.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Turnstone Systems, Inc.

We have audited the accompanying
consolidated statement of net assets in liquidation of Turnstone Systems, Inc. and subsidiaries as of December 31, 2006, and the related consolidated statements of changes in net assets in liquidation for each of the years in the two-year period
ended December 31, 2006. These consolidated financial statements are the responsibility of the Companys management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits.

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

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the net
assets in liquidation of Turnstone Systems, Inc. and subsidiaries as of December 31, 2006 and the changes in their net assets in liquidation for each of the years in the two-year period ended December 31, 2006, in conformity with U.S. generally
accepted accounting principles.

TURNSTONE SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



|1. | Description Of Business
|-- | -----------------------

On August 6, 2003, the Board of Directors of
Turnstone Systems, Inc. (the Company) approved, subject to the approval by stockholders, a plan to liquidate and dissolve the Company (the Plan). The Plan was approved by a majority of the Companys stockholders on
November 11, 2003. The key features of the Plan are (1) file a Certificate of Dissolution with the Secretary of State of the State of Delaware; (2) cease conducting normal business operations, except as may be required to wind up the
Companys business affairs; (3) attempt to convert all of the Companys remaining assets into cash or cash equivalents in an orderly fashion; (4) pay or attempt to adequately provide for the payment of all of the Companys
known obligations and liabilities; and (5) distribute pro rata in one or more liquidating distributions all of the Companys remaining assets to its stockholders as of the applicable record date.

The Company formerly developed and marketed products that enable local exchange carriers to rapidly deploy and efficiently maintain copper local loop services.



|2. | Significant Accounting Policies
|-- | -------------------------------

Basis Of Presentation

As a result of the stockholders approval of the Plan and the imminent nature of the liquidation, the Company adopted the liquidation basis of accounting
effective November 11, 2003. This basis of accounting is considered appropriate when, among other things, liquidation of a company is probable and the net realizable value of assets are reasonably determinable. Under this basis of accounting,
assets are valued at their estimated net realizable values and liabilities are stated at their estimated settlement amounts.

Use of Estimates

The preparation of consolidated financial statements in conformity with generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported results of operations during the reporting period. Actual results
could differ from those estimates.

Cash and Cash Equivalents

The Company considers all highly liquid investments purchased with an original maturity of less than three months at the date of purchase to be cash equivalents. Cash equivalents at December 31, 2006 consisted primarily of money market
funds.



|3. | Litigation
|-- | ----------

IPO Litigation

On November 9, 2001, Arthur Mendoza filed a securities class action lawsuit in the United States District Court for the Southern District of New York alleging claims
against the Company, certain of its current and former officers and directors, and the underwriters of the Companys initial public offering of stock as well as the Companys secondary offering of stock. The complaint is purportedly
brought on behalf of a class of individuals who purchased common stock in the Companys initial public offering and secondary stock offering between January 31 and December 6, 2000. The complaint alleges generally that the
prospectuses under which such securities were sold contained false and misleading statements with respect to discounts and commissions received by the underwriters. The case has been coordinated for pre-trial purposes with over 300 cases
raising the same or similar issues and also currently pending in the Southern District of New York. On April 18, 2002, Michael Szymanowski was appointed lead plaintiff in the action. On April 22, 2002, an amended complaint was filed. On
July 1, 2002, the underwriter defendants filed an omnibus motion to dismiss. On July 15, 2002, the Company, collectively with the other issuer defendants, also filed an omnibus motion to dismiss. The lead plaintiff filed an opposition to
the underwriters motion to dismiss on August 15, 2002 and to the issuers motion to dismiss on August 27, 2002. The underwriters reply to the opposition was filed on September 13, 2002, and the Companys reply to
the opposition was filed on September 27, 2002. On February 19, 2003, the district court



17



---

##### Table of Contents

issued an order denying the motions to dismiss with respect to substantially all of the plaintiffs claims, including those against us. In February
2005, the district court granted preliminary approval for a proposed settlement and release of claims against the issuer defendants, including Turnstone. In April, June and October 2006, the district court judge met with the issuer defendants and
their insurance companies to review the fairness of the proposed settlement. In December 2006, as a result of an appeal by the underwriter defendants, the second circuit court of appeals issued a decision to decertify the class action. As a result,
the district court has stayed the proposed settlement pending plaintiffs appeal of the decertification decision. Plaintiffs in this class action lawsuit have claimed damages in the hundreds of millions of dollars. If the settlement does not
occur, and litigation against the Company continues, the Company believes it has meritorious defenses and intends to defend the case vigorously. The Company does not estimate that there will be future costs associated with this case and has not
included costs associated with this case in estimated litigation settlement costs at December 31, 2006.

|ITEM 8A(T). |  | CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures
as of the end of the period covered by this Annual Report on Form 10-KSB. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Companys disclosure controls and procedures are effective to ensure
that information we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules
and forms.

Our significant personnel reductions during 2003 have affected the overall control environment. As of December 31, 2006, there are no
employees of the company. One consultant, Eric S. Yeaman, is the Chief Executive Officer and Chief Financial Officer. However, management does not believe that these personnel reductions have had a significant impact on the effectiveness of the
design and operation of the Companys disclosure controls and procedures.

Changes in Internal Controls Over Financial Reporting

There has been no change in our internal controls over financial reporting that occurred during the period covered by this Annual Report on Form 10-KSB
that has materially affected or is reasonably likely to materially affect, our internal controls over financial reporting.

##### Table of Contents

BOARD OF DIRECTORS

Prior to our 2003 Annual Meeting, our certificate of incorporation divided our board of directors into three classes. Each class consisted of one-third of the total number of directors. All directors in a given class served contemporaneous
three-year terms. At our 2003 Annual Meeting, our stockholders approved the amendment of our certificate of incorporation to eliminate the classification of our board of directors.

During the period from January 1, 2003 to December 2, 2003, our board of directors consisted of six members. On December 2, 2003, all of
the then existing directors except for Mr. John K. Peters resigned from the board and Messrs. Liu and Yeaman, our executive officers, were appointed to the board of directors. In June 2004, Mr. Peters resigned from the board.
Directors are elected for a one-year term so that the term of all directors expires each year. A director serves for the designated term and until his or her respective successor is elected or appointed, or until the director's death, resignation or
removal. Stockholders are not entitled to cumulative voting in the election of directors.

BOARD COMMITTEES AND MEETINGS

During fiscal 2006, our board of directors did not hold any meetings.

We established an audit committee in October 1999. The audit committee reviews our internal accounting procedures and consults with and reviews the services provided by our independent accountants. There is no
specified term for committee members. During fiscal 2004, Mr. Peters served as the sole member of our audit committee until his resignation in June 2004. Since then, our board of directors has acted as the audit committee. Our board of
directors has determined that Mr. Yeaman is an audit committee financial expert. Mr. Yeaman is not an independent director, as that term is used in Item 7(d)(3)(iv) of Schedule 14A under the Securities and Exchange Act.
The audit committee did not meet in fiscal 2006.

LEGAL PROCEEDINGS

Certain of our current and former directors and officers have been named as co-defendants in legal proceedings against us. See Certain Relationships and Related Transactions below for information regarding
these specific legal proceedings and our indemnity obligations.

COMPLIANCE WITH SECTION 16(A) OF THE EXCHANGE ACT

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires that our officers and directors and persons who own more than 10% of a
registered class of our equity securities file reports of ownership on Form 3 and changes in ownership on Forms 4 or 5 with the Securities and Exchange Commission. These officers, directors, and 10% stockholders are also required by SEC rules to
furnish us with copies of all Section 16(a) reports they file. Based solely on our review of the copies of forms we have received, or written representations from certain reporting persons, we believe that all of our executive officers and
directors have complied with all applicable filing requirements for the fiscal year ended December 31, 2006.

CODE OF ETHICS

We have adopted a financial code of ethics that applies to our principal executive officer, principal financial officer, principal accounting officer and
all of our employees. You may request a free copy of our financial code of ethics, which is one of several policies within our code of business conduct, by sending your request together with a self-addressed, postage-paid, envelope to Turnstone

OPTION GRANTS IN LAST FISCAL YEAR

We did not grant any
stock options to our executives and employees during the fiscal year ended December 31, 2006. All of our option plans were terminated on December 4, 2003, when our certificate of dissolution became effective with the office of the
Secretary of State of the State of Delaware. Therefore, there are no options outstanding or exercisable as of December 31, 2006.

AGGREGATE OPTION
EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION VALUES

As all of our options plans were terminated on December 4, 2003, there
were no option exercises in fiscal 2006.

DIRECTOR COMPENSATION

In June 2004, we entered into consulting agreements with Albert Y. Liu and Eric S. Yeaman to continue ongoing management of our liquidation, including service as our board of directors. Compensation under these
consulting agreements is based on actual hours of service at a fixed hourly rate of $125. The agreements do not provide for minimum retainer payments or termination fees.

EMPLOYMENT AGREEMENTS AND CHANGE IN CONTROL ARRANGEMENTS

In October 2003, we entered into an employment agreement with each
of Messrs. Liu and Yeaman. The employment agreement provided that in the event we terminate the officers employment without cause, the officer will be entitled to receive a severance payment equal to six months of his annual base salary. At
the end of June 2004, we terminated the employment of Messrs. Liu and Yeaman, and concurrently entered into consulting agreements with each of them to continue ongoing management of our liquidation. Compensation under these consulting agreements is
based on actual hours of service at a fixed hourly rate of $125. The agreements do not provide for minimum retainer payments or termination fees.



|ITEM 11. | SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS
|-------- | ----------------------------------------------------------------------------------------------

The following table sets forth certain information with respect to beneficial ownership of our common stock as of February 1, 2006, by: (i) each
person who is known by us to own beneficially more than five percent of our common stock, (ii) each of our named

##### Table of Contents

executive officers, (iii) each of our directors, and (iv) all directors and named executive officers as a group. Except as indicated in the
footnotes to this table, the persons named in the table have sole voting and investment power with respect to all shares of common stock shown as beneficially owned by them, subject to community property laws where applicable.

Beneficial ownership is determined based on the rules of the Securities and Exchange Commission. The column entitled Number of Shares Beneficially
Owned excludes the number of shares of common stock subject to options held by that person that are currently exercisable or that will become exercisable within 60 days after the record date. The number of shares subject to options that each
beneficial owner has the right to acquire within 60 days of the record date is listed separately under the column entitled Number of Shares Underlying Options Beneficially Owned. These shares are not deemed outstanding for purposes of
computing the percentage ownership of any other person. Unless otherwise indicated in the footnotes, these stockholders have sole voting or investment power with respect to all shares, subject to applicable community property laws. The number and
percentage of shares beneficially owned are based on 63,417,130 shares outstanding as of February 1, 2007.

|ITEM 12. | CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE
|-------- | -------------------------------------------------------------------------

In addition to the indemnification provisions contained in our certificate of incorporation and bylaws, we have entered into separate indemnification agreements with each of our directors. These agreements require us,
among other things, to indemnify such director against expenses (including attorneys fees), judgments, fines and settlements paid by such individual in connection with any action, suit or proceeding arising out of such individuals status
or service as our director or officer (other than such liabilities arising from willful misconduct or conduct that is knowingly fraudulent or deliberately dishonest) and to advance expenses incurred by such individual in connection with any
proceeding against such individual with respect to which such individual may be entitled to indemnification by us. We have been named as defendants in a class action lawsuit generally referred to as IPO Allocation claims relating to our
initial public offering in January 2000. Certain of our current and former officers and directors have been named as co-defendants in this class action lawsuit and we may be required to indemnify these persons in connection with the lawsuit.

During fiscal 2006, there has not been, nor is there currently proposed, any transaction or series of similar transactions to which we
were or are to be a party, in which the amount involved in the transaction exceeds $60,000 and in which any director, executive officer or holder of more than 5% of our capital stock had or will have a direct or indirect material interest, other
than compensation arrangements which are otherwise described under "Executive Compensation  Employment Agreements and Change in Control Agreements."

|ITEM 14. | PRINCIPAL ACCOUNTANT FEES AND SERVICES
|-------- | --------------------------------------

The following
table sets forth the aggregate fees billed to us by KPMG LLP, independent accountants, for professional services rendered for the fiscal years ended December 31, 2006 and December 31, 2005.



|                   |  |             |        |             |   |

|All Other Fees     |  |             |       |             |   |      
|                   |  |             |        |             |   |       
|                   |  |            
|Total Fees         |  | $           | 58,000 |             | $ | 58,000
|                   |  |             |        |             |   |       

Audit Fees. Consists of fees billed for professional services rendered for the audit of our
consolidated financial statements and review of the interim consolidated financial statements included in our quarterly reports and services that are normally provided by KPMG LLP in connection with statutory and regulatory filings or engagements,
and attest services, except those not required by statute or regulation.

Audit-Related Fees. Consists of fees billed for assurance
and related services that are reasonably related to the performance of the audit or review of our consolidated financial statements and are not reported under Audit Fees. KPMG did not bill us for any such services in fiscal 2006 or 2005.

Tax Fees. Consists of fees billed for professional services for tax compliance, tax advice and tax planning. In fiscal 2005 and
2006 KPMG LLP provided U.S. tax compliance and consultation services.

All Other Fees. KPMG LLP did not bill us for any other fees.

The Audit Committee considered and determined that the provision of the services other than the services described under Audit
Fee and Audit-Related Fees is compatible with maintaining the independence of the independent auditors.

POLICY ON AUDIT COMMITTEE
PRE-APPROVAL OF AUDIT AND PERMISSIBLE NON-AUDIT SERVICES OF INDEPENDENT AUDITORS

The Audit Committees policy is to pre-approve all
audit and audit-related services provided by the independent auditors. These services may include audit services, audit-related services, tax services and other services. The independent auditors are required to periodically report to the Audit
Committee regarding the extent of services provided by the independent auditors in accordance with such pre-approval. In fiscal years 2006 and 2005, all fees identified above under the captions Audit Fees, and Tax Fees that
were billed by KPMG LLP were approved by the Audit Committee in accordance with SEC requirements.
