▇▇▇▇▇▇▇, ▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

The undersigned purchaser (the “Purchaser”) hereby agrees to purchase from PreCheck Health Services, Inc., a Florida corporation (the “Company”), the Company’s 8% promissory note due December 31, 2020 (the “Note,” and, together the other notes of like tenor issues pursuant to note purchase agreements, the “Notes”) in the amount set forth on the signature page of this Agreement at a purchase price equal to the principal amount of the Note. The Notes shall be in substantially the form of Exhibit A to this Agreement. The Company is offering up to $270,000 principal amount of Notes; however, there is no minimum principal amount of Notes which must be sold. The Company may, in its sole discretion and without notice to the Purchaser, increase the principal amount of Notes being offered. The Notes will be sold in the minimum principal amount of $100,000; however, the Company may, in its sole discretion, accept subscriptions for an investment of less than $100,000. Payment of the Notes will be secured by a pledge in the stock of ▇▇▇ Practice Management, Inc., a Texas corporation doing business as ▇▇▇ Consulting, Inc. (“▇▇▇”) pursuant to a pledge agreement, to be executed contemporaneously with the acquisition by the Company of the stock of ▇▇▇ pursuant to a stock purchase agreement dated July 17, 2019 between the Company and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, as amended by an amendment dated December 19, 2019 (the “▇▇▇ Agreement”). The security interest in the stock of ▇▇▇ will be pari passu with the security interest to be held by the stockholders of ▇▇▇ in the $250,000 Notes to be issued to the stockholders of ▇▇▇ pursuant to the ▇▇▇ Agreement.

1. The Purchaser shall pay the Purchase Price by wire transfer in accordance with instructions by the Company contemporaneously with the execution of this Agreement.

2. The Company represents and warrants to the Purchaser as follows:

(a) The Company is a corporation organized, validly existing and in good standing under the laws of the State of Florida, has all requisite power and authority to own and operate its properties and assets and to carry on its business as presently and proposed to be conducted. The Company has not failed to qualify to transact business as a foreign corporation in any jurisdiction where the failure to be so qualified would materially and adversely affect the business, properties, prospects or financial conditions of the Company (a “Material Adverse Effect”).

(b) This Agreement and the Notes have been authorized by board of directors of the Company and, when executed by the Company and the Purchaser, will constitute the valid and binding agreements of the Company, enforceable in accordance with their respective terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium, liquidation, fraudulent conveyance and other similar laws relating to, or affecting generally, the enforcement of creditors’ rights and remedies and except that remedies that the grant equitable relief are in the discretion of the court.

(c) The execution, delivery and performance by the Company of this Agreement and the consummation of the transactions contemplated hereby will not, with or without the passage of time or giving of notice, result in any such material violation or default or result in the creation of any material lien, charge or encumbrance upon any asses of the Company or the suspension, revocation, impairment, forfeiture or nonrenewal of any material permit, license, authorization or approval applicable to the Company, its business or operations, or any of its assets or properties.

(d) There is no action, suit, proceeding or investigation pending or, to the Company’s knowledge, currently threatened against the Company that questions the validity of this Agreement or the Notes or the right of the Company to enter into this Agreement, to issue the Notes or to consummate the transactions contemplated hereby, or that could reasonably be expected to result, if determined adversely to the Company, in a Material Adverse Effect. The Company is not a party to, or to the Company’s knowledge named in, any order, writ, injunction, judgment or decree of any court, government agency or instrumentality.

(e) Subject in part to the truth and accuracy of the Purchaser’s representations set forth in this Agreement, the offer, sale and issuance of the Notes as contemplated by this Agreement are exempt from the registration requirements of the Securities Act, and neither the Company nor any authorized agent acting on its behalf will take any action hereafter that would cause the loss of such exemption.

(f) The Company has provided the Purchaser with all the information reasonably available to the Company that the Purchaser has requested for deciding whether to purchase the Notes. The Purchaser acknowledges that the Company’s filings under the Securities Act and the Securities Exchange Act of 1934 are available to the public through the Securities and Exchange Commission’s ▇▇▇▇▇ system.

(g) Neither the Company nor any of its executive officers, directors, 10% of greater equity holders (nor any other Company-related person covered by the applicable statute) is subject to any of the “bad actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the Securities Act or disclosure requirements of Rule 506(e).

(h) No broker, finder or investment banker is entitled to any brokerage, finder’s or other fee or commission in connection with the transactions contemplated by this Agreement based upon arrangements made by or on behalf of the Company.

3. The Purchaser hereby represents, warrants, covenants and agrees as follows:

(a) The Purchaser understands that the offer and sale of the Notes is being made only by means of this Agreement. The Purchaser understands that the Company has not authorized the use of, and the Purchaser confirms that he is not relying upon, any other information, written or oral, other than material contained in this Agreement. The Purchaser is aware that the purchase of the Notes involves a high degree of risk and that the Purchaser may sustain, and has the financial ability to sustain, the loss of his entire investment. The Purchaser understands that the Company is operating at a loss, and can give no assurance that the Company will ever be profitable, and the Company will need additional financing both to enable it to pay the Notes when they become due and for its operations, and the failure of the Company to raise additional funds when required is likely to have a material adverse effect upon its business and its ability to pay the Notes and to continue in business, and any financing may result in dilution to the Company’s stockholders. In purchasing the Note, the Purchaser is not relying upon any projections, forecasts or any statements of any kind relating to future revenue, earnings, operations or cash flow. The Purchase understands that the Company is using the proceeds from the sale of the loan to fund the initial payment due for the purchase of ▇▇▇ pursuant to the ▇▇▇ Agreement and for expenses relating to a proposed financing by the Company. The Purchaser understands that in the event that that Company is not able to sell all of the $270,000 principal amount of Notes offered, the Company may not have sufficient funds for its immediate cash requirement or to acquire ▇▇▇. The Company will require the completion of its proposed financing to pay a note to the stockholders of ▇▇▇ and to operate its business and the Company can give no assurance that the financing will be completed. The Purchaser understands that, in the event that the Company does not consummate the acquisition of ▇▇▇, the Notes will be unsecured. The Purchaser understands that ▇▇▇ does not have audited financial statements.

(b) In connection with its purchase of the Notes, the Purchaser understands that the Company’s business is subject to numerous risks, including the risk that the Company may not be able to sell all of the Notes offered and complete a financing which will be necessary to enable the Company to pay the Note as well as the note in the amount of $250,000 to be issued to the stockholders of ▇▇▇ and to provide the Company funds to pay its bank financing which is due in May 2020, as well as funds for its operations as well as the risk that the Company may not consummate the acquisition of ▇▇▇. The Company can give no assurance that it will be able to raise the necessary funding. The Purchaser is familiar with the medical equipment business and the significant risks involved in entering into such a business, and the Purchaser has the ability to evaluate the risks inherent in the purchase of debt securities issued by the Company.

(c) The Purchaser understands that there is no minimum offering and, accordingly, it is possible that the Company may not sell any Notes other than those previously sold, if any, and the Notes purchased by the Purchaser. The failure of the Company to sell all of the Notes offered may impair its ability to make the acquisition of ▇▇▇ and to develop its business and operations.

(d) The Purchaser is an accredited investor and the information set forth in the Accredited Investor Questionnaire, which is set forth as Exhibit B, is true and correct.

(e) The Purchaser is a sophisticated investor, with significant prior investment experience, including investment in early stage companies. The Purchaser is knowledgeable about investment considerations in unregistered and restricted securities and securities issued by early-stage development companies. The Purchaser has a sufficient net worth to sustain a loss of his entire investment in the Company and recognizes the possibility that he may sustain the loss of his entire investment. The Purchaser’s overall commitment to investments which are not readily marketable is not excessive in view of the Purchaser’s net worth and financial circumstances and the purchase of the Notes will not cause such commitment to become excessive. The investment is a suitable investment for the Purchaser. The Purchaser has engaged its own counsel, accountants and investment advisors to the extent that the Purchaser deems it necessary. The Company has given no assurance that it will be able to raise funds prior to the maturity date of the Note, and its failure to do so may impair its ability to pay the principal amount of the Notes at maturity as well as its ability to develop its business.

(f) The Purchaser is acquiring the Notes for investment and not with a view to the sale or distribution thereof, for the Purchaser’s own account and not on behalf of others; has not granted any other person any interest or participation in or right or option to purchase all or any portion of the Notes.

(g) The Purchaser will not transfer any Notes except in compliance with all applicable federal and state securities laws and regulations, and, in such connection, the Company may request an opinion of counsel reasonably acceptable to it as to the availability of any exemption.

(h) If the Purchaser is a citizen or resident of any country other than the United States, the Purchaser has taken such steps as he deems necessary to satisfy itself that the purchase of the Noes by the Purchase is not in violation of the laws of such country.

(i) The Purchaser represents and warrants that no broker or finder was involved directly or indirectly in connection with the Purchaser’s purchase of the Notes pursuant to this Agreement. The Purchaser shall indemnify the Company and hold it harmless from and against any manner of loss, liability, damage or expense, including fees and expenses of counsel, resulting from a breach of the Purchaser’s warranty contained in this Section 3(i).

(j) The Purchaser has a pre-existing relationship with the Company and its management (“preexisting relationship”). A preexisting relationship includes any relationship consisting of personal or business contacts of a nature to enable an issuer to evaluate a prospective investor’s sophistication, financial circumstances, and ability to understand the nature and risks related to an investment in the issuer.

(k) The Purchaser acknowledges and agrees that the Company will refuse to register any transfer of the Notes that is not made pursuant to an available exemption from the registration requirements of the Securities Act and in accordance with applicable state securities laws.

(l) The funds used to pay the Purchase Price were not and are not directly or indirectly derived from activities that contravene (i) United States federal, state, or international laws and regulations, including anti-money laundering laws and regulations or (ii) anti-money laundering and similar laws and regulations of the country in which the Purchaser is a citizen or resident. United States federal regulations and Executive Orders administered by Office of Foreign Assets Control (“OFAC”) prohibit, among other things, the engagement in transactions with, and the provision of services to, certain foreign countries, territories, entities and individuals. The lists of OFAC prohibited countries, territories, persons and entities can be found on the OFAC website at ▇▇▇▇://▇▇▇.▇▇▇▇▇.▇▇▇/▇▇▇▇. In addition, the programs administered by OFAC (the “OFAC Programs”) prohibit dealing with individuals or entities in certain countries regardless of whether such individuals or entities appear on the OFAC lists.

(m) To the best of the Purchaser’s knowledge, none of: (i) the Purchaser; (ii) any person controlling or controlled by the Purchaser; (iii) any person having a beneficial interest in the Purchaser; or (iv) any person for whom the Purchaser is acting as agent or nominee in connection with the purchase of the Notes:
