The Chiu M. Chan Family Trust is a trust governed by the laws of Texas. The address for the Chiu M. Chan Family Trust is 323 Wood Loop St., Houston, Texas 77015. The purpose of the Chiu M. Chan Family Trust is to hold and manage certain assets received from the Estate of Chiu M. Chan, pursuant to the instructions provided in the Last Will & Testament of Chiu M. Chan dated December 11, 1992 and First Codicil thereto dated March 16, 1998 which were admitted to probate on July 5, 2012 in Cause No. 413,798 in Probate Court No. 3 of Harris County, Texas (the “Last Will & Testament”). Ms. Chan is the sole trustee of the Chiu M. Chan Family Trust.

During the last five years, no Reporting Person has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). In addition, during the last five years, no Reporting Person has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding been subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration.

Ella Y. T. C. Chan beneficially owns 4,199,160 shares of Common Stock. 1,610,205 of these shares of Common Stock were acquired by Ms. Chan in July 1992 through the use of her personal funds. The remaining 2,588,955 shares of Common Stock were transferred to her on May 21, 2013 in respect of her community property interest in the Estate of Chiu M. Chan.

The Chiu M. Chan Family Trust acquired 4,199,160 shares of Common Stock on May 21, 2013 pursuant to the distribution from the Estate of Chiu M. Chan.

Item 4. Purpose of Transaction.

Ella Y. T. C. Chan acquired her 4,199,160 shares of Common Stock in July 1992 and May 21, 2013 for investment purposes.

The Chiu M. Chan Family Trust acquired 4,199,160 shares of Common Stock on May 21, 2013 to hold and manage certain assets received from the Estate of Chiu M. Chan, pursuant to the instructions provided in the Last Will & Testament.

On December 18, 2015, Dr. Eric K. Chan and CEMEKC, Inc. (“CEMEKC” and collectively with Dr. Chan, the “Other Group Members”) together with the Reporting Persons commenced a tender offer. Dr. Chan is the sole owner, officer and director of the CEMEKC and the Chief Executive Officer, President and sole director of the Company. He is the son of Ella Y. T. C. Chan. The tender offer is disclosed in a Tender Offer Statement and Rule 13e-3 Transaction Statement filed under cover of Schedule TO by the Other Group Members and the Reporting Persons (collectively, the “Offeror”) with the United States Securities and Exchange Commission (the “SEC”) on December 18, 2015 (the “Schedule TO”). The Offeror filed amendments to the Schedule TO with the SEC on January 4, 2016, January 8, 2016, January 21, 2016, January 25, 2016 and February 8, 2016. The Offeror sought to acquire all of the issued and outstanding shares of Common Stock that they do not already own, for $0.10 per share, net to the seller in cash, without interest, less any applicable withholding taxes (the “Offer Price”), upon the terms and subject to the conditions set forth in the Offer to Purchase and related Letter of Transmittal dated December 18, 2015 (both of which are included in the Schedule TO), which, collectively with any amendments or supplements thereto, are referred to as the “Offer.” If upon completion of the Offer the Offeror owned at least 90% of the outstanding shares of Common Stock, on that basis they would have been entitled to acquire the remaining shares of Common Stock by way of a “short-form” merger at the same per share cash price paid in the Offer. The Offer, as extended, expired on February 5, 2016. CEMEKC accepted for payment all 587,539 shares of Common Stock that were validly tendered in the Offer, and payment for such shares will be made promptly in accordance with the terms of the Offer.

As the number of shares of Common Stock validly tendered and accepted for payment in the Offer did not reach or exceed 90% of the shares outstanding immediately prior to the expiration of the Offer, CEMEKC cannot and will not effect the short-form merger. Therefore, as was discussed in the Offer, the Company’s current management, under the general direction of the current Board of the Company, will continue to manage the Company as an ongoing business.

The Reporting Persons together with the Other Group Members may engage in other transactions for the purposes of purchasing all the outstanding shares of Common Stock not already owned by them in the future. In particular they may consider:

engaging in open-market or privately-negotiated purchases of shares of Common Stock to increase their aggregate beneficial ownership to at least 90% of the then-outstanding Common Stock and then effecting a “short-form” merger pursuant to the Nevada Revised Statutes 92A;

proposing that CEMEKC and the Company enter into a merger agreement, which would require the approval of the Company’s Board (of which Dr. Chan is the sole member) and the vote of the shares of Common Stock in favor of the merger agreement; or

keeping outstanding the public minority interest in the Company, in which case the public stockholders of the Company would, absent a sale by them in the public markets, retain their shares of Common Stock.

The Reporting Persons together with the Other Group Members may constitute a group under the meaning of Rule 13d-5 of the Securities Exchange Act of 1934, as amended, because of their collective actions in connection with the Offer.

Nothing contained in this Schedule 13D shall be construed as an admission that any of the Reporting Persons is the beneficial owner of any Other Group Members’ Common Stock and each Reporting Person expressly disclaims the beneficial ownership of the Common Stock owned by the Other Group Members.

Except as disclosed in this Item 4, none of the Reporting Persons have any other current plans or proposals which relate to or would result in any of the events described in clauses (a) through (j) of the instructions to Item 4 of Schedule 13D. The Reporting Persons, however, will take such actions with respect to its investments in the Company as deemed appropriate in light of existing circumstances from time to time and reserve the right to acquire or dispose of securities of the Company, or to formulate other purposes, plans or proposals in the future depending on market conditions or other factors.

Item 5. Interest in Securities of the Issuer.

All information relating to percentage ownership of the Company’s Common Stock set forth in this Schedule 13D is as of the date hereof, based upon the 13,601,624 shares of Common Stock reported by the Company to be issued and outstanding as of January 11, 2016 in its Form 10-Q filed with the Securities and Exchange Commission on January 14, 2016.

As of the date of this Schedule 13D, the Reporting Persons and the Other Group Members own an aggregate of 9,435,670 shares of Common Stock, which constitutes 68.12% of the Common Stock. Such shares include options to acquire 250,000 shares of Common Stock, which are currently exercisable, held by Dr. Chan.

(b) Each of the Reporting Persons and the Other Group Members has the sole power to vote or direct the vote, and the sole power to dispose or to direct the disposition of, all the shares of Common Stock beneficially owned by such Reporting Person or Other Group Member.

(c) Except for CEMEKC’s purchase of the 587,539 shares of Common Stock that were validly tendered in the Offer described in Item 4 above, none of the Reporting Persons or Other Group Members effected any transactions in Common Stock during the past 60 days.

(d) Ms. Chan and the Chiu M. Chan Family Trust each have the power to receive or power to direct the receipt of dividends from, or proceeds from the sale of, the shares of Common Stock held in the Chiu M. Chan Family Trust.

(e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.
