This Proxy Statement and the GOLD proxy card are first being furnished to stockholders on or about [November     , 2010].

Each of the Nominees has consented to being named in this Proxy Statement and, if elected, to serve as a director.

OUR NOMINEES ARE COMMITTED TO ACTING IN THE BEST INTERESTS OF ALL STOCKHOLDERS. WE BELIEVE THAT ALL STOCKHOLDER ASPIRATIONS TO CREATE VALUE CAN BEST BE ACHIEVED THROUGH THE ELECTION OF OUR NOMINEES. ACCORDINGLY, THE PARTICIPANTS URGE YOU TO VOTE FOR OUR

NOMINEES, BERNHARD BRUSCHA, FREDERICK G. THIEL, AND HOSHI PRINTER, AS DIRECTORS.

THIS SOLICITATION IS BEING MADE BY THE PARTICIPANTS AND NOT ON BEHALF OF THE BOARD OF DIRECTORS OF THE COMPANY.

According to the preliminary proxy statement of Lantronix (“Lantronix’s Proxy Statement”) filed with the Securities and Exchange Commission, or SEC, on October 7, 2010, holders of record of Lantronix’s voting securities as of the close of business on October 26, 2010 (the “Record Date”) are entitled to notice of, and to attend and to vote at, the Annual Meeting and any adjournments or postponements thereof.

PROPOSAL ONE

ELECTION OF DIRECTORS

The Company’s Board of Directors currently consists of nine (9) members. The terms of all nine directors will expire at the Annual Meeting. On August 19, 2010, we delivered a letter to Lantronix, notifying Lantronix that we, as Lantronix’s largest stockholder, intend to nominate the following three (3) Nominees for election as directors at the Annual Meeting: Bernhard Bruscha, Frederick G. Thiel and Hoshi Printer. Each Nominee, if elected, would serve a one-year term and hold office until the 2011 annual meeting of stockholders and until a successor has been duly elected and qualified. Background information about each of the Nominees is set forth below. According to Lantronix’s Proxy Statement, the Board of Directors of Lantronix intends to nominate six (6) incumbent candidates for election as directors at the Annual Meeting. You should refer to Lantronix’s Proxy Statement for the names, backgrounds, qualifications and other information concerning Lantronix’s nominees.

VOTE FOR OUR NOMINEES BY USING THE ENCLOSED GOLD PROXY TO VOTE TODAY—BY TELEPHONE, BY INTERNET, OR BY MARKING, SIGNING, DATING AND RETURNING THE GOLD PROXY CARD IN THE POSTAGE-PAID ENVELOPE PROVIDED TO YOU.

This proxy statement is soliciting proxies to elect Bernhard Bruscha, Frederick G. Thiel and Hoshi Printer. Under applicable proxy rules, given the size of the Board and the number of persons nominated by us and Lantronix, we are required either to solicit proxies for our three Nominees, or to solicit proxies for our three Nominees and all six of Lantronix’s nominees. Because we do not endorse the nomination of certain Lantronix nominees, we are not seeking authority to vote for, and WILL NOT exercise any authority to vote for, Lantronix’s nominees. You may also withhold authority with respect to any Nominee by writing the name of that nominee on the enclosed GOLD proxy card.

Background Information with respect to TL Investment’s Nominees

The following information sets forth the name, age, business address, present principal occupation and employment, and material occupations for at least the past five years, for each of our three Nominees. Please see Annexes A and B for additional information about our Nominees’ beneficial ownership and purchases and sales of shares of Lantronix Common Stock during the past two years, respectively.

Bernhard Bruscha, 57, has been a member of the Company’s Board of Directors since August 2007. Mr. Bruscha served as Chairman of the Company’s Board of Directors from June 1989 to May 2002, and has been the Company’s largest stockholder, with beneficial ownership of approximately [38.3]% of its outstanding Common Stock as of the Record Date. Mr. Bruscha started his career in the 1970s, as one of three founding partners in a computer networking software company and for more than 20 years has successfully founded, grown and sold or merged several technology and other companies. Since May 2002, Mr. Bruscha has served as Chairman of the Supervisory Board of transtec AG, a computer systems manufacturer and direct computer reseller and also is an active designer of software systems. Mr. Bruscha is also Managing Director of TL Investment GmbH and Managing Director of technovest alpha Gmbh

- 3 -

located in Tübingen, Germany. Mr. Bruscha is not on the board of any public company or any company registered as an investment company under the Investment Company Act of 1940. Three international customers of the Company, transtec AG, barix AG and Lynx IT-Systeme GmbH (previously known as Triple Stor GmbH), are related parties of Lantronix due to common ownership by Mr. Bruscha, accounting for approximately 1% and 2% of the Company’s net revenues for the 2010 and 2009 fiscal years, respectively, according to Lantronix’s Proxy Statement. Mr. Bruscha’s business address is Biesingerstrasse 27, Tuebingen 72070, Germany.

As reflected in the biographical information summarized above, Mr. Bruscha has extensive business, managerial, executive and leadership experience in the technology industry, having founded several technology distribution and hardware companies. In addition, Mr. Bruscha is a current director of Lantronix and, as the sole owner and one of two managing directors of TL Investment (Lantronix’s largest and longest-term stockholder), Mr. Bruscha is committed to maximizing long-term value for all Lantronix stockholders. For these reasons, TL Investment believes that Mr. Bruscha has the requisite set of skills and experience to continue to serve as a valuable member of the Board of Directors of the Company.

Frederick G. Thiel, 50, has been a Managing Partner of Triton Pacific Capital Partners LLC, a private equity firm investing in lower- to mid-market privately held companies in North America, since 2007. Before that, Mr. Thiel was a self-employed business consultant from 2005 to 2006. Mr. Thiel has over 20 years of experience managing software and technology companies. Prior to joining Triton Pacific, Mr. Thiel had been CEO of several companies including GameSpy Industries, a leader in on-line media, and Lantronix from April 1998 to May 2002. Mr. Thiel is not on the board of any public company or any company registered as an investment company under the Investment Company Act of 1940. Mr. Thiel attended the Stockholm School of Economics, and is fluent in English, Spanish, Swedish and French. Mr. Thiel’s business address is 10877 Wilshire Blvd., 12th Floor, Los Angeles, CA 90024.

As reflected in the biographical information summarized above, Mr. Thiel has extensive business, managerial, executive, financial and leadership experience in the software and technology industries. As the former President and Chief Executive Officer of Lantronix, as well as a former member of the Board of Directors of Lantronix, Mr. Thiel is uniquely suited to help the Board of Directors manage Lantronix’s strategic initiatives and leverage its assets into an effective growth strategy. Given his impressive and substantial skills and experience, TL Investment believes that Mr. Thiel would be a tremendous addition to the Company’s Board of Directors.

Hoshi Printer, 68, has four decades of relevant general and financial management experience, including serving as chief financial officer for several successful technology companies including Autobytel, one of the largest online automotive marketplaces, Peerless Systems Corporation, an industry leader in embedded imaging systems, Neuron Data, developers of high-end, client-server, object- and web-oriented tools, Soane Technologies, an ophthalmic and bioscience business, and Catalytica, developers of pioneering environmental technology. Mr. Printer spent a significant portion of the beginning of his career at Xerox Corporation, the world’s leading enterprise for business process and document management, where he spent a total of 17 years, the last six of which he served as Vice President of Finance for a large division of Xerox. Mr. Printer has participated in three initial public offerings and has substantial

- 4 -

experience in the financial management of public companies. Since 2005, Mr. Printer has been a Chief Financial Officer consultant, including with Private Access, Inc., a technology company, from January 2010 to the present, with Trustin Technology LLC, a supply chain management solution provider, from April 2007 through February 2008, with Avamar Technologies, Inc., a provider of enterprise data protection software, from January 2006 through January 2007, and with Path 1 Network Technologies, a leader in the evolution of broadcast television over IP and now a division of IP Video Networks, Inc., from May 2005 through October 2005. Mr. Printer was also engaged in business development with Tatum, LLC, a human capital solutions provider, from April 2008 through December 2009. Mr. Printer was president of the Software Council of Southern California in 2003-2004, and has been a board member of the Forum for Corporate Directors for the last four years. Mr. Printer holds B.S. degrees in both Mechanical and Electrical Engineering, an M.S. degree in Industrial Engineering, and an M.B.A. from the Stanford Business School. Mr. Printer is not on the board of any public company or any company registered as an investment company under the Investment Company Act of 1940. Mr. Printer’s business address is 15 Classico Dr., Newport Coast, CA 92657.

As reflected in the biographical information summarized above, Mr. Printer has extensive business, managerial, executive, financial and leadership experience in multiple industries, including the technology industry. Mr. Printer has extensive financial and accounting experience and would be considered an “audit committee financial expert” as such term is defined under applicable rules of the SEC. Given his impressive and substantial skills and experience, TL Investment believes that Mr. Printer would also be a tremendous addition to the Company’s Board of Directors.

Independence of Nominees

Under Nasdaq Listing Rules, the Company’s Board of Directors determines whether a director is deemed to be independent under the standards adopted by Nasdaq. The Nasdaq Listing Rules and associated interpretations provide for certain relationships which would automatically disqualify a director from being deemed independent by the Board of Directors. In addition, the Board of Directors has the discretion to determine whether any director has a relationship which would interfere with the exercise of independent judgment in carrying out the responsibilities of that director, even if such relationship was not specifically enumerated under the Nasdaq Listing Rules.

The Company’s Board of Directors has historically determined, in its discretion, that Mr. Bruscha is not considered independent under the independence requirements of The NASDAQ Stock Market, Inc. and the independence standards applicable to Lantronix under paragraph (a)(1) of Item 407 of Regulation S-K under the Securities Exchange Act of 1934, as amended.

As previously reported by the Company in certain of its filings with the SEC, in 2001, the Company loaned Mr. Thiel approximately $3,040,645 in aggregate principal amount, primarily related to the payment of taxes on stock options exercised by Mr. Thiel. The notes evidencing this indebtedness are secured by shares of common stock held by Mr. Thiel, and bear interest at rates ranging from 5.19% to 7.50% per annum. Principal and any unpaid interest are due upon any transfer or disposition of the shares of common stock securing the notes. Otherwise, there is no stated maturity date of the notes. As of the Record Date, Mr. Thiel’s total debt outstanding to Lantronix, including accrued interest, was $            . Accordingly, it is possible that Lantronix’s Board of Directors, as constituted following the Annual Meeting, could conclude, in its discretion, that Mr. Thiel’s outstanding indebtedness to the Company would interfere with Mr. Thiel’s exercise of independent judgment in carrying out his responsibilities as a director of Lantronix, and therefore, would not consider Mr. Thiel independent under applicable Nasdaq Listing Rules.

Mr. Printer would not be barred from being considered independent under the independence requirements of The NASDAQ Stock Market, Inc. and the independence standards

- 5 -

applicable to Lantronix under paragraph (a)(1) of Item 407 of Regulation S-K under the Securities Exchange Act of 1934, as amended.

WE STRONGLY URGE YOU TO VOTE FOR THE ELECTION OF BERNHARD BRUSCHA, FREDERICK G. THIEL AND HOSHI PRINTER BY MARKING, SIGNING, DATING AND RETURNING THE ENCLOSED GOLD PROXY CARD IN THE POSTAGE PAID ENVELOPE PROVIDED TO YOU WITH THIS PROXY STATEMENT OR BY USING THE GOLD PROXY CARD TO VOTE BY TELEPHONE OR INTERNET. IF YOU HAVE SIGNED THE GOLD PROXY CARD AND NO MARKING IS MADE, YOU WILL BE DEEMED TO HAVE GIVEN A DIRECTION TO VOTE ALL THE SHARES REPRESENTED BY THE GOLD PROXY CARD FOR THE ELECTION OF BERNHARD BRUSCHA, FREDERICK G. THIEL AND HOSHI PRINTER.

OTHER MATTERS TO BE CONSIDERED AT THE ANNUAL MEETING

According to Lantronix’s Proxy Statement, Lantronix is soliciting proxies with respect to three proposals other than the election of directors. Please refer to Lantronix’s Proxy Statement for a detailed discussion of these proposals. For your convenience, these proposals are outlined briefly below. IF YOU HAVE SIGNED THE GOLD PROXY CARD AND NO MARKING IS MADE, YOU WILL BE DEEMED TO HAVE GIVEN A DIRECTION TO VOTE ALL OF THE SHARES REPRESENTED BY YOUR GOLD PROXY CARD (I) FOR PROPOSALS [    ] BELOW, AND (II) AGAINST PROPOSALS [    ] BELOW.

PROPOSAL TWO

APPROVAL OF LANTRONIX’S 2010 STOCK INCENTIVE PLAN

According to Lantronix’s Proxy Statement, the Company will also solicit proxies with respect to a proposal for the stockholders to approve Lantronix’s 2010 Stock Incentive Plan. Please refer to Lantronix’s Proxy Statement for a discussion of such proposal. The Participants intend to vote, and recommend that you vote, [    ] this proposal.

PROPOSAL THREE

APPROVAL OF AMENDMENT OF LANTRONIX’S CERTIFICATE OF

INCORPORATION REDUCING THE NUMBER OF AUTHORIZED COMMON SHARES

According to Lantronix’s Proxy Statement, the Company will also solicit proxies with respect to a proposal for the stockholders to approve an amendment to the Company’s Certificate of Incorporation reducing the number of common shares authorized from 200,000,000 to 100,000,000. Please refer to Lantronix’s Proxy Statement for a discussion of such proposal. The Participants intend to vote, and recommend that you vote, [    ] this proposal.

PROPOSAL FOUR

RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

- 6 -

According to Lantronix’s Proxy Statement, the stockholders will be asked to vote to ratify the selection of McGladrey & Pullen, LLP as the Company’s independent registered public accountants for the fiscal year ending June 30, 2011. Please refer to Lantronix’s Proxy Statement for a discussion of such proposal. The Participants intend to vote, and recommend that you vote, [    ] this proposal.

OTHER PROPOSALS

The Participants know of no other business to be presented at the Annual Meeting. If any other matters should properly come before the Annual Meeting, it is intended that the persons named on the enclosed GOLD proxy card will vote that proxy on such other matters in accordance with their judgment.

VOTING PROCEDURES

According to Lantronix’s Proxy Statement, the Bylaws and applicable law, holders of shares of Lantronix’s Common Stock, at the close of business on the Record Date are entitled to notice of, and to vote at, the Annual Meeting. Each share of Common Stock outstanding on the Record Date is entitled to one vote on each matter presented at the Annual Meeting.

Quorum

According to Lantronix’s Proxy Statement, the Bylaws and applicable law, the required quorum for the transaction of business at the Annual Meeting is a majority of the shares of Common Stock outstanding on the Record Date and entitled to vote at the Annual Meeting, present in person or represented by proxy. Abstentions and broker non-votes are each included in the determination of the number of shares present and voting for the purpose of determining whether a quorum is present.

Abstentions

When an eligible voter attends the Annual Meeting but decides not to vote, his or her decision not to vote is called an “abstention.” Properly executed proxy cards that are marked “abstain” or “withhold authority” on any proposal will be treated as abstentions for that proposal. Abstention shares will be treated as not voting for purposes of determining the outcome on any proposal for which the minimum vote required for approval of the proposal is a plurality of the votes actually cast. Abstention shares will have the same effect as votes against a proposal if the minimum vote required for approval of the proposal is a majority (or some other percentage) of (i) the shares present and entitled to vote, or (ii) all shares outstanding and entitled to vote.

Broker Non-Votes

Broker non-votes occur when shares held by a broker for a beneficial owner are not voted with respect to a particular proposal because (i) the broker does not receive voting instructions from the beneficial owner, and (ii) the broker lacks discretionary authority to vote the shares. Broker non-votes will not be treated as shares present and entitled to vote for purposes of any matter requiring the affirmative vote of a majority or other proportion of the shares present and entitled to vote (even though the same shares may be considered present for quorum purposes

- 7 -

and may be entitled to vote on other matters). Thus, a broker non-vote will not affect the outcome of the voting on a proposal the passage of which requires the affirmative vote of a plurality (or a majority or some other percentage) of (i) the votes cast or (ii) the voting power present and entitled to vote on that proposal. Broker non-votes will have the same effect as a vote against a proposal the passage of which requires an affirmative vote of the holders of a majority (or some other percentage) of the shares outstanding as of the Record Date.

Vote Required

Proposal One: Directors are elected by a plurality of the votes cast by the holders of Lantronix’s Common Stock at a meeting at which a quorum is present. Plurality means that the individuals who receive the largest number of votes cast are elected as directors, up to the maximum number of directors to be chosen at the meeting. Consequently, any shares not voted (whether by abstention, broker non-vote or otherwise) will have no impact on the election of directors.

Proposal Two: The approval of Lantronix’s 2010 Stock Incentive Plan requires the affirmative approval of a majority of the shares present in person or represented by proxy and entitled to vote at the Annual Meeting. Consequently, abstentions will be treated as votes against this proposal. Broker non-votes will not be treated as shares present and entitled to vote, and therefore broker non-votes will have no effect on the outcome of this proposal.

Proposal Three: The approval of Lantronix’s amendment to its Certificate of Incorporation to reduce the number of authorized shares of Common Stock requires the affirmative approval of a majority of the shares of the Company’s common stock outstanding on the Record Date. Consequently, any shares not voted (whether by abstention, broker non-vote or otherwise) will have the effect of a vote against this proposal.

Proposal Four: The proposal to ratify the selection of McGladrey & Pullen, LLP as the Company’s independent registered public accountants for the fiscal year ending June 30, 2011 requires the affirmative approval of a majority of the shares present in person or represented by proxy and entitled to vote at the Annual Meeting. Consequently, abstentions will be treated as votes against this proposal. Because the ratification of the independent registered public accounting firm is a discretionary matter, broker non-votes will not result for this proposal.

How to Vote

As explained in the detailed instructions on your GOLD proxy card, there are four ways you may vote. You may:

1. Sign, date and return the enclosed GOLD proxy card in the enclosed postage-paid envelope. We recommend that you vote on the GOLD proxy card even if you plan to attend the Annual Meeting;

• submitting a properly executed, subsequently dated GOLD proxy card that will revoke all prior proxy cards, including any Company proxy cards which you may have submitted to Lantronix;

• instructing us by telephone or via the Internet as to how you would like your shares voted (instructions are on your GOLD proxy card);

• attending the Annual Meeting and withdrawing his or her proxy by voting in person (although attendance at the Annual Meeting will not in and of itself constitute revocation of a proxy); or

• delivering written notice of revocation either to TL Investment c/o D.F. King & Co., Inc., 48 Wall Street, 22^nd Floor, New York, NY 10005, or the Corporate Secretary of Lantronix.

IF YOU PREVIOUSLY SIGNED AND RETURNED A WHITE PROXY CARD TO LANTRONIX, WE URGE YOU TO REVOKE IT BY (1) MARKING, SIGNING, DATING AND RETURNING THE GOLD PROXY CARD, (2) INSTRUCTING US BY TELEPHONE OR VIA THE INTERNET AS TO HOW YOU WOULD LIKE YOUR SHARES VOTED WITH RESPECT TO THE GOLD PROXY CARD, (3) ATTENDING THE ANNUAL MEETING AND VOTING IN PERSON OR (4) DELIVERING A WRITTEN NOTICE OF REVOCATION TO TL INVESTMENT OR TO THE CORPORATE SECRETARY OF LANTRONIX.

COST AND METHOD OF SOLICITATION

We have retained D.F. King & Co., Inc. (“D.F. King”) to conduct the solicitation, for which D.F. King is to receive a fee not to exceed $35,000, plus reimbursement for its reasonable out-of-pocket expenses. TL Investment has agreed to indemnify D.F. King against certain liabilities and expenses, including certain liabilities under the federal securities laws. Insofar as indemnification for liabilities arising under the federal securities laws may be permitted to D.F. King pursuant to the foregoing provisions, we have been informed, that in the opinion of the SEC, such indemnification is against public policy and may therefore be unenforceable. Proxies may be solicited by mail, courier services, Internet, advertising, telephone or telecopier or in person. It is anticipated that D.F. King will employ up to five persons to solicit proxies from Lantronix stockholders for the Annual Meeting. The total expenditures in furtherance of, or in connection with, the solicitation of proxies is approximately [$            ] to date, and is estimated to be [$            ] in total.

Proxies may also be solicited by TL Investment and the other Participants (including the Nominees). Banks, brokerage houses, and other custodians, nominees, and fiduciaries will be requested to forward our solicitation material to their customers for whom they hold shares and

- 10 -

the TL Investment will reimburse them for their reasonable out-of-pocket expenses. Our proxy materials are available on the following web site: www.LTRXshareholders.com.

The entire expense of preparing, assembling, printing, and mailing this proxy statement and related materials and the cost of soliciting proxies will be borne by TL Investment. TL Investment does not intend to seek reimbursement for the costs and expenses associated with the proxy solicitation in the event that any of the Nominees are elected to the Board of Directors of Lantronix.
