Additional risks and uncertainties not currently known to us or that we currently deem not to be material also may impair our business operations.

CAUTIONARY INFORMATION REGARDING
FORWARD-LOOKING STATEMENTS
 
Certain statements made in this prospectus that are not statements of historical or current facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements may involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from historical results or from any future results expressed or implied by such forward-looking statements.
 
In addition to statements that explicitly describe such risks and uncertainties, you are urged to consider statements in future or conditional tenses or that include terms such as “believes,” “belief,” “expects,” “intends,” “anticipates” or “plans” to be uncertain and forward-looking. Forward-looking statements may include comments as to our beliefs and expectations as to future events and trends affecting our business. Forward-looking statements are based upon our current expectations concerning future events and trends and are necessarily subject to uncertainties, many of which are outside of our control. The factors incorporated by reference under the heading “Risk Factors” above and those described in our other SEC reports, as well as other factors, could cause actual results to differ materially from those reflected or predicted in forward-looking statements.
 
Any forward-looking statements are based on our beliefs and assumptions, using information currently available to us. We assume no obligation, and do not intend, to update these forward-looking statements.
 
If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, actual results may vary materially from those reflected in or suggested by forward-looking statements. Any forward-looking statement you read in this prospectus reflects our views with respect to future events and is subject to these and other risks, uncertainties and assumptions relating to our operations, results of operations, growth strategy and liquidity. All subsequent written and oral forward-looking statements attributable to us or individuals acting on our behalf are expressly qualified in their entirety by this paragraph. You should specifically consider the factors identified or referred to in this prospectus and our other SEC reports, including our Annual Report on Form 10-K for the year ended December 31, 2006, as amended by Form 10-K/A, and our Quarterly Report on Form 10-Q for the quarter ended June 30, 2007, which could cause actual results to differ from those referred to in forward-looking statements.

THE OFFERING
 
On June 19, 2007, we sold 1,250,000 shares of our common stock to the selling stockholders in a private placement transaction. We received $20,562,500 in net proceeds from the sale after deducting $1,312,500 in commissions paid to the placement agents for these shares. We issued these shares in reliance on the exemption from registration provided by Regulation D under the Securities Act of 1933. We issued the shares without general solicitation or advertising. The purchasers were a limited number of accredited investors with access to all relevant information necessary to evaluate the investment, and who represented to us that the shares were being acquired for investment for their own account.
 
Under the terms of the purchase agreements under which these shares were issued and a related registration rights agreement, we agreed to use commercially reasonable efforts to file a registration statement covering the resale of the shares within 90 calendar days after June 19, 2007 and to use our reasonable efforts to cause that registration statement to be declared effective. We also agreed to prepare and file any amendments that are necessary to keep the registration statement current and effective for a period ending the earlier of (i) June 19, 2009; (ii) the date on which the selling stockholders may sell the shares covered by this prospectus without restriction by the volume limitations of Rule 144(e) under the Securities Act of 1933; or (iii) such time as all of the shares covered by this prospectus have been sold (A) pursuant to a registration statement, (B) to or through a broker, dealer or underwriter in a public distribution or a public securities transaction, or (C) in a transaction exempt from the registration and prospectus delivery requirements under Section 4(1) of the Securities Act so that all transfer restrictions and restrictive legends, if any, are removed upon the consummation of such sale.
 
USE OF PROCEEDS

  •  broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;
 
  •  a combination of any such methods of sale; and
 
  •  any other method permitted pursuant to applicable law.
 
The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the shares of common stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus.
 
In connection with the sale of our common stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our common stock short and deliver these securities to close out their short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).
 
The aggregate proceeds to the selling stockholders from the sale of the common stock offered by them will be the price at which they sell the common stock less discounts or commissions, if any. Each of the selling stockholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase by a third party of common stock to be sold by the selling stockholders directly or through agents. We will not receive any of the proceeds from this offering.
 
The selling stockholders also may resell all or a portion of the shares in open market transactions in reliance upon Rule 144 under the Securities Act of 1933, provided that they meet the criteria and conform to the requirements of that rule.
 
The selling stockholders and any broker-dealers that act in connection with the sale of securities registered pursuant to this prospectus may be deemed to be “underwriters” within the meaning of Section 2(11) of the Securities Act, and any commissions received by such broker-dealers and any profit on the resale of the securities sold by them while acting as principals may be deemed to be underwriting discounts or commissions under the Securities Act. Each selling stockholder has represented and warranted to the company that it does not have any agreement or understanding, directly or indirectly, with any Person to distribute shares.
 
To the extent required, the shares of our common stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealers or underwriters, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.
 
In order to comply with the securities laws of some states, if applicable, the common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the common stock may not be sold unless it has been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.
 
We have advised the selling stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the selling stockholders and their affiliates. Regulation M’s prohibition on purchases may include purchases to cover short positions by the

selling stockholders, and a selling stockholder’s failure to cover a short position at a lender’s request and subsequent purchases by the lender in the open market of shares to cover such short positions, may be deemed to constitute an inducement to buy shares, which is prohibited by Regulation M.
 
We will make copies of this prospectus (as it may be supplemented or amended from time to time) available to the selling stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act. The selling stockholders may indemnify any broker-dealer that participates in transactions involving the sale of the shares against certain liabilities, including liabilities arising under the Securities Act.
 
We have advised the selling stockholders that if a particular offer of shares is to be made on terms constituting a material change from the information described under a final prospectus, then, to the extent required, a supplement to the final prospectus must be distributed setting forth the terms and related information as required.
 
We have agreed to indemnify the selling stockholders against liabilities, including liabilities under the Securities Act and state securities laws, relating to the registration of the shares offered by this prospectus.
 
DESCRIPTION OF CAPITAL STOCK
 
Our authorized capital stock consists of 60,000,000 shares of common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share.
 
As of July 31, 2007, we had the following equity securities outstanding:
 
  •  22,142,123 million shares of common stock;
 
  •  no shares of preferred stock; and
 
  •  1,102,225 options to purchase a like number of shares of common stock.
 
The following description of our capital stock does not purport to be complete and is subject to and qualified by our Certificate of Incorporation, as amended, and by our Amended and Restated By-Laws, and by the applicable provisions of Delaware law.
 
Common Stock
 
Our common stock is traded on The Nasdaq Global Market under the symbol “TDSC.” Holders of our common stock are entitled to one vote for each share on all matters voted upon by our stockholders, including the election of directors, and do not have cumulative voting rights.
 
Subject to the rights of holders of any then outstanding shares of our preferred stock, our common stockholders are entitled to receive ratably any dividends out of assets legally available therefor as our Board of Directors may from time to time determine. We do not currently pay dividends on our common stock. For a description of our dividend policy, please refer to Item 5, “Market for Our Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities” in our Annual Report on Form 10-K, as amended by Form 10-K/A, for the year ended December 31, 2006 which has been incorporated by reference in this prospectus. Holders of our common stock are entitled to share ratably in our net assets upon our dissolution or liquidation, after payment or provision for all liabilities and any pari passu or preferential liquidation rights of our preferred stock then outstanding.
 
Holders of our common stock have no preemptive rights to purchase shares of our stock. The shares of our common stock are not subject to any redemption provisions and are not convertible into any other shares of our capital stock. All outstanding shares of our common stock are fully paid and nonassessable. The rights, preferences and privileges of holders of our common stock are subject to those of the holders of preferred stock, and will be subject to those of the holders of any shares of our preferred stock we may issue in the future.

Preferred Stock
 
The Board of Directors may, from time to time, authorize the issuance of one or more classes or series of preferred stock without stockholder approval up to the maximum of 5,000,000 shares of preferred stock that are authorized. Subject to the provisions of our Certificate of Incorporation, as amended, and limitations prescribed by law, the Board of Directors is authorized to adopt resolutions to issue shares, establish the number of shares, change the number of shares constituting any series and provide or change the voting powers, designations, preferences and relative rights, qualifications, limitations or restrictions on shares of our preferred stock, including dividend rights, terms of redemption, conversion rights and liquidation preferences, in each case without any action or vote by the stockholders. We have no current intention to issue any additional series or classes of preferred stock.
 
Although we have no current intention to take any such action, one of the effects of the Board of Directors’ right to designate and issue preferred stock without stockholder approval may be to enable the Board of Directors to discourage an attempt to obtain control of the company by means of a tender offer, proxy contest, merger or otherwise. Further, although we have no current intention to take any such action, the issuance of preferred stock may adversely affect the rights of our common stockholders by, among other things:
 
  •  restricting dividends on the common stock;
 
  •  diluting the voting power of the common stock;
 
  •  impairing the liquidation rights of the common stock; or
 
  •  delaying or preventing a change in control without further action by the stockholders.
 
Options
 
As of July 31, 2007, options covering a total of 1,102,225 shares of common stock were outstanding. Of such amount, options to purchase approximately 34,166 shares remained unvested and were not exercisable as of such date. The remaining stock options become exercisable prior to the end of 2007.
 
LEGAL MATTERS
 
The validity of the issuance of the shares of common stock offered hereby will be passed upon for us by Robert M. Grace, Jr., our Vice President, General Counsel and Secretary. As of July 31, 2007, Mr. Grace beneficially owned 40,112 shares of our common stock and also beneficially owned options to purchase an additional 40,000 shares of our common stock.

Item 14.   Indemnification of Directors and Officers.
 
Section 145 of the Delaware General Corporation Law authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers in terms sufficiently broad to permit such indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act of 1933.
 
As permitted by the Delaware General Corporation Law, our Certificate of Incorporation, as amended, includes a provision that eliminates the personal liability of our directors for monetary damages for breach of fiduciary duty as a director, except for liability:
 
  •  for any breach of the director’s duty of loyalty to us or our stockholders;
 
  •  for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law;
 
  •  under section 174 of the Delaware General Corporation law regarding unlawful dividends and stock purchases; or
 
  •  for any transaction for which the director derived an improper personal benefit.
 
As permitted by the Delaware General Corporation Law, our Amended and Restated By-Laws provide that:
 
  •  with respect to any action or proceeding not brought by us, we have the power to indemnify any person who was or is a party or is threatened to be made a party to any action or proceeding if that person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of our company, and with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful;
 
  •  with respect to any action or proceeding brought by us, we have the power to indemnify any person who was or is a party or is threatened to be made a party to any action or proceeding if that person acted in good faith and in a manner that he or she reasonably believed to be in or not opposed to the best interests of our company; provided, however, that no indemnification shall be made in respect of any claim, issue or matter as to which that person is adjudged to be liable to us, unless, and only to the extent that, the court determines that the person is fairly and reasonably entitled to indemnity;
 
  •  to the extent that a director, officer, employee or agent of our company has been successful on the merits or otherwise in defense of any action or proceeding, he or she shall be indemnified against expenses incurred by him or her;
 
  •  expenses incurred in defending a civil or criminal action or proceeding shall be paid by us in advance of the final disposition of the action or proceeding upon receipt of an undertaking by or on behalf of


II-1


Table of Contents

  the director, officer, employee or agent to repay that amount if it is ultimately determined that he or she is not entitled to indemnification; and
 
  •  the rights conferred in the Amended and Restated By-Laws are not exclusive.
 
We have entered into indemnification agreements with certain of our directors to give these directors additional contractual assurances regarding the scope of the indemnification set forth in our amended Certificate of Incorporation and to provide additional procedural protections. At present, there is no pending litigation or proceeding involving any of our directors, officers or employees regarding which indemnification is sought, nor are we aware of any threatened litigation that may result in claims for indemnification.
 
Item 15.   Recent Sales of Unregistered Securities
 
In the past three years we have sold securities in the transactions described below that were not registered under the Securities Act.
 
On July 20, 2007, $14,845,000 aggregate principal amount of our 6% Convertible Subordinated Debentures were converted into 1,458,266 shares of our common stock in connection with the conditional call for redemption of those Debentures that we issued on June 21, 2007. The holders of the other $7,759,000 aggregate principal amount of these debentures had previously exercised their conversion rights with respect to the Debentures. The total number of shares of common stock issued in connection with the conversion of all the Debentures was 2,230,273 shares. The Debentures were originally sold to such holders in private transactions in November and December 2003. These shares of common stock were issued in reliance on the exemption from registration provided by Section 3(a)(9) of the Securities Act of 1933 for any security exchanged by an issuer with its existing security holders exclusively where no commission or other remuneration is paid or given directly or indirectly for soliciting such exchange.
 
On June 19, 2007, we sold the 1,250,000 shares of our common stock that are covered by this registration statement through placement agents, Canaccord Adams Inc. and Johnson Rice & Company LLC, to accredited investors in a private placement transaction. In connection with the offering the placement agents were paid aggregate commissions of $1,312,500. Under the terms of the purchase agreements entered into in connection with this sale we agreed to use commercially reasonable efforts to file a registration statement covering the shares within 90 calendar days after the closing date, use commercially reasonable efforts to cause that registration statement to become effective, and thereafter to prepare and file such amendments as to keep that registration statement current and effective for a period ending the earlier of (i) the second anniversary of the closing date; (ii) the date on which the purchasers may sell the shares covered by this registration statement held by them without restriction by the volume limitations of Rule 144(e) under the Securities Act; or (iii) such time as all of the shares covered by this registration statement have been sold (A) pursuant to a registration statement, (B) to or through a broker, dealer or underwriter in a public distribution or a public securities transaction, or (C) in a transaction exempt from the registration and prospectus delivery requirements of the Securities Act under Section 4(1) thereof so that all transfer restrictions and restrictive legends with respect thereto, if any, are removed upon the consummation of such sale. We received $20,562,500 of net proceeds from these sales. The transaction was exempt from the registration requirements of the Securities Act of 1933 pursuant to Section 4(2) of the Securities Act or Regulation D promulgated thereunder, as such sales were made without general solicitation or advertising, and each purchaser was an accredited investor with access to all relevant information necessary to evaluate the investment and whom represented to us that the securities we being acquired for investment for their own account.
 
On June 8, 2006 all of the outstanding shares of our Series B Convertible Preferred Stock were converted into shares of our common stock in connection with a conditional call for redemption that we issued on May 8, 2006. As a result we issued 2,639,772 shares of common stock to the holders of the Preferred Stock. This Preferred Stock was originally sold to such holders in a private transaction in May 2003. These shares of common stock, as well as shares of common stock issued upon previous conversions, were issued in reliance on the exemption from registration provided by Section 3(a)(9) of the Securities Act of 1933 for any security exchanged by an issuer with its existing security holders exclusively where no commission or other remuneration is paid or given directly or indirectly for soliciting such exchange.

Table of Contents

On December 30, 2004, $9,900,000 aggregate principal amount of our 7% Convertible Subordinated Debentures were converted into 824,979 shares of our common stock in connection with a conditional call for redemption of these Debentures that we issued on December 2, 2004. The holders of the other $100,000 aggregate principal amount of these debentures had previously exercised their conversion rights with respect to the Debentures during the fourth quarter of 2004. The total number of shares of common stock issued in connection with the conversion of all the Debentures was 833,312 shares. The Debentures were originally sold to such holders in a private transaction in December 2001. These shares of common stock were issued in reliance on the exemption from registration provided by Section 3(a)(9) of the Securities Act of 1933 for any security exchanged by an issuer with its existing security holders exclusively where no commission or other remuneration is paid or given directly or indirectly for soliciting such exchange.
 
Item 16.   Exhibits and Financial Statement Schedules.
 
(a) Exhibits.  A list of exhibits filed with this registration statement on Form S-1 is set forth on the Exhibit Index and is incorporated in this Item 16(a) by reference.
 
(b) Financial Statement Schedules.  Other financial statement schedules are omitted because the information called for is not required or is shown either in our consolidated financial statements or the notes thereto, which are incorporated by reference to the SEC filings listed above.
 
Item 17.   Undertakings.
 
The undersigned registrant hereby undertakes:
 
(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement; (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information in the registration statement. Notwithstanding the foregoing, any increase or decrease in the amount of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in amount and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
 
(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and
 
(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
 
(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described in Item 14 above, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
