2.05

Maximum Number of Shares of TSLU Common Stock to be Issued; Effect on Outstanding Securities of Chembio, Merger Sub

.  The consideration to be paid by TSLU in connection with the Merger shall be the Merger Consideration. On the terms and subject to the conditions of this Agreement, as of the Effective Time, by virtue of the Merger and without any action on the part of TSLU or Merger Sub, Chembio or the holder of any shares of Chembio Common Stock or Chembio Options, the following shall occur:

(a)

Conversion of Chembio Common Stock.  At the Effective Time, each share of Chembio Common Stock issued and outstanding immediately prior to the Effective Time (other than any shares of Chembio Common Stock to be canceled pursuant to Section 2.05(c) and any Dissenting Shares (as defined and provided in Section 2.06)) will be canceled and extinguished and be converted automatically into the right to receive that number of shares of TSLU Common Stock equal to the Exchange Ratio.

(b)

Fractional Shares.  No fractional shares of TSLU Common Stock shall be issued pursuant to the Merger, but in lieu thereof, the number shares of TSLU Common Stock to be received by each holder of Chembio Common Stock who would otherwise be entitled to a fraction of a share of TSLU Common Stock (after aggregating all fractional shares of TSLU Common Stock to be received by such holder) shall be rounded up or down to the nearest whole share.

Cancellation of TSLU-Owned and Chembio-Owned Stock.  Each share of Chembio Common Stock owned by TSLU or Chembio or any Subsidiary of TSLU or Chembio immediately prior to the Effective Time shall be automatically canceled and extinguished without any conversion thereof and without any further action on the part of TSLU, Merger Sub or Chembio.

(d)

Capital Stock of Merger Sub.  Each share of Merger Sub Common Stock, par value $0.001 per share, that is issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of Common Stock, par value $0.001 per share of the Surviving Corporation.  From and after the Effective Time, each share certificate of Merger Sub theretofore evidencing ownership of any such shares shall continue to evidence ownership of such shares of Common Stock of the Surviving Corporation.

(e)

Chembio Stock Options.  At the Effective Time, Chembio’s 1999 Stock Option Plan (the “Chembio Stock Option Plan”) and all Chembio Options then outstanding under Chembio Stock Option Plan shall be assumed by TSLU (each such Chembio Option an “Assumed Option” and collectively the “Assumed Options”).  At the Effective Time, the Chembio Stock Option Plan shall be renamed the TSLU Stock Option Plan.  Each Assumed Option shall continue to have, and be subject to, the same terms and conditions under the TSLU Stock Option Plan as set forth in the Chembio Stock Option Plan  as in effect immediately prior to the Effective Time, except that (i) each Assumed Option will be exercisable for TSLU Common Stock based on the Option Exchange Amount; and (ii) the per share exercise price for the shares of TSLU Common Stock issuable upon exercise of each Assumed Option will be equal to the quotient obtained by dividing (x) the exercise price per share of Chembio Common Stock at which such Assumed Option was exercisable immediately prior to the Effective Time, by (y) the Exchange Ratio, rounded up to the nearest whole cent.  It is the intention of the parties that the Assumed Options continue to qualify, to the maximum extent possible, following the Effective Time as incentive stock options as defined in Section 422 of the Internal Revenue Code to the extent such options qualified as incentive options prior to the Effective Time.  To evidence the assumption of the Assumed Options by TSLU, TSLU will issue to each holder of an Assumed Option a replacement TSLU Stock Option Plan stock award agreement.

(g)

 Adjustments to Exchange Ratio and Option Exchange Amounts.  The Exchange Ratio and the Option Exchange Amounts shall be equitably adjusted to reflect fully the effect of any stock split, reverse split, stock combination, stock dividend (including any dividend or distribution of securities convertible into TSLU Common Stock or Chembio Common Stock), reorganization, reclassification, recapitalization or other like change with respect to TSLU Common Stock or Chembio Common Stock occurring after the date hereof and prior to the Effective Time.

2.06 Dissenting Shares.

         (a) Notwithstanding anything in this Agreement to the contrary, shares of Chembio Common Stock that are issued and outstanding immediately prior to the Effective Time and the holders of which demand and perfect their Appraisal Rights for such shares in the time and manner provided under DGCL and, as of the time provided under DGCL, have neither effectively withdrawn nor lost their rights to such appraisal and payment under DGCL (the "Dissenting Shares") shall not be converted into or represent a right to receive the Merger Consideration, but shall, by virtue of the Merger, be entitled to only such rights as are granted by the DGCL; provided, however, that if such holder shall have failed to perfect or shall have effectively withdrawn or lost his Appraisal Rights under the DGCL, such holder's shares of Chembio Common Stock shall thereupon be deemed to have been converted, at the Effective Time, as described in Section 2.05(a), into the right to receive the applicable Merger Consideration set forth in such provisions, without any interest thereon.

         (b) Chembio shall give TSLU (1) prompt notice of any demands for appraisal pursuant to DGCL received by Chembio, withdrawals of such demands, and any other instruments served pursuant to the DGCL and received by Chembio and (2) the opportunity to direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. Chembio shall not, except with the prior written consent of TSLU or as otherwise required by applicable law, make any payment with respect to any such demands for appraisal or offer to settle or settle any such demands.

         (c) Mailing of Notices. Promptly following the Effective Time, Chembio shall mail to each holder of record of Chembio Shares, as of the record date fixed by Chembio's board of directors who did not execute a Stockholders' Consent, the notices of the Merger and of the Appraisal Rights available to such Chembio stockholders as provided by the DGCL.

Exchange Procedures.

TSLU Common Stock. On the Closing Date, TSLU shall deposit with the Exchange Agent, for exchange in accordance with this Article 2, the Merger Consideration.

(b)

Exchange Procedures.  As soon as practicable after the Effective Time, the Surviving Corporation shall cause to be mailed to each holder of record of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Chembio Common Stock (the “Certificates”) and which shares were converted into shares of TSLU Common Stock, (i) a letter of transmittal in customary form (which shall specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent and shall be in such form and have such other provisions as TSLU may reasonably specify) and (ii) instructions for use in effecting the surrender of the Certificates in exchange for certificates representing shares of TSLU Common Stock.  Upon surrender of a Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by TSLU, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, the holder of such Certificate shall be entitled to receive in exchange therefor a certificate representing the number of whole shares of TSLU Common Stock, and the Certificate so surrendered shall be canceled. Until surrendered, each outstanding Certificate that, prior to the Effective Time, represented shares of Chembio Common Stock will be deemed from and after the Effective Time, for all corporate purposes, other than the payment of dividends, to evidence the ownership of the amount of cash and the number of full shares of TSLU Common Stock into which such shares of Chembio Common Stock shall have been so converted.

(c)

Distributions With Respect to Unexchanged Shares of Chembio Common Stock.  No dividends or other distributions with respect to TSLU Common Stock declared or made after the Effective Time and with a record date after the Effective Time will be paid to the holder of any unsurrendered Certificate with respect to the shares of TSLU Common Stock represented thereby until the holder of record of such Certificate shall surrender such Certificate to the Exchange Agent in accordance with Section 2.07(b).  Subject to applicable Law, following surrender of any such Certificate, there shall be paid to the record holder of the certificates representing whole shares of TSLU Common Stock issued in exchange therefor, without interest, at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such whole shares of TSLU Common Stock.

(e)

Transfers of Ownership.  If any certificate for shares of TSLU Common Stock is to be issued pursuant to the Merger in a name other than that in which the Certificate surrendered in exchange therefor is registered, it will be a condition of the issuance thereof that the Certificate so surrendered will be properly endorsed and otherwise in proper form for transfer and that the person requesting such exchange will have paid to TSLU or any agent designated by it any transfer or other taxes required by reason of the issuance of a certificate for shares of TSLU Common Stock in any name other than that of the registered holder of the Certificate surrendered, or established to the satisfaction of TSLU or any agent designated by it that such tax has been paid or is not payable.

2.08

No Further Ownership Rights in Chembio Common Stock

.  All shares of TSLU Common Stock issued upon the surrender for exchange of shares of Chembio Common Stock in accordance with the terms hereof (including any cash paid in respect of fractional shares thereof) shall be deemed to have been issued in full satisfaction of all rights pertaining to such shares of Chembio Common Stock, and there shall be no further registration of transfers on the records of Chembio of shares of Chembio Common Stock which were outstanding immediately prior to the Effective Time.  If, after the Effective Time, Certificates are presented to the Surviving Corporation for any reason, they shall be canceled and exchanged as provided in this Article 2.

2.09

Lost, Stolen or Destroyed Certificates

.  In the event any Certificates shall have been lost, stolen or destroyed, the Exchange Agent shall issue certificates representing such shares of TSLU Common Stock in exchange for such lost, stolen or destroyed Certificates, upon the making of an affidavit of that fact by the holder thereof; provided, however, that TSLU or the Exchange Agent may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed Certificates to provide an indemnity or deliver a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against TSLU or the Exchange Agent with respect to the Certificates alleged to have been lost, stolen or destroyed.

2.10

Taking of Necessary Action; Further Action

.  If, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement or to vest the Surviving Corporation with full right, title and possession to all assets, property, rights, privileges, powers and franchises of Chembio, the officers and directors of the Surviving Corporation shall be fully authorized to take, and shall take all such lawful and necessary action.
